Beth Rowley

September 27, 2020

Supporting artists during lockdown

   

If your spine tingled to the introductory music to the BBC drama Strike (click here) you’re a Beth Rowley fan. She comes from my birthtown, Bristol, and has released two albums. I think she’s right up there with Adele and Amy Winehouse. But it was through Strike that I discovered her. Normally I’d have played her on Spotify and checked if she ever performed near Nottingham. But she won’t be touring now.

Until streaming came along, musicians used to make most of their money from LP & CD sales. Then live performance took over, surely a good thing.  Now that has stopped we need to go back to buying CDs. Her latest Gota Fria is £11.99 on Amazon, and an extra 95p on her own website. I love Amazon but they are doing well out of lockdown. I still have a job and less to spend my money on, so the latter it was (click here).

It’s a wonderful record. Time to buy Little Dreamer.

OASI care bundle evaluation project

September 23, 2020

A well-conducted study, but an unclear result

I admit it. I was sceptical. A stepped wedge (type of cluster) trial evaluating a “care bundle” (leaflets, a manoevre called the “Finnish grip”, 60o episiotomy & routine rectal examination) with, at best, a shaky evidence base (click here & here), evaluated by researchers who clearly already believed in it, and driven by two political organisations (RCM & RCOG) whose leaders felt that “something must be done” and were claiming success even before it started (2016 links no longer available). When the project ended, and more press releases announced success (2018 links not available), without any results appearing for over two years, I feared the worst; sample size changes, centres excluded for “low compliance”, participants disappearing from analysis groups, outcome switching, statistical shenanigans.

The “Finnish grip” is a bit odd too. Although mentioned on the Care Bundle website (click here), it doesn’t appear in the protocol or trial registry – I did a word search. Both call the 3rd element “Manual perineal protection”. The “Finnish grip” is mentioned, but not described, in the main trial report, and the references cited as sources (click here and here) describe it as “a technique for guiding the head through the introitus by gripping the baby’s chin with a flexed middle finger of the other hand”. They both refer to (Pirhonen et al 1998 click here) as the original source. In 1998 Jouko Pirhonen was a trainee in Lund, Sweden, and he is now a professor in Oslo, Norway. But Pirhonen is a Finnish name, and his co-authors included three obstetricians (no midwives) from Finland. They wrote:

“The delivery assistant presses the baby’s head with her left hand to control the speed of crowning through the vaginal introitus. Simultaneously, using the thumb and index finger of the right hand to support the perineum while the flexed middle finger is used to take a grip on the baby’s chin. When a good grip has been achieved, the woman is asked to stop pushing, to breathe rapidly, while the midwife slowly helps baby’s head through the vaginal introitus. When most of the head is out, the perineal ring is pushed under the baby’s chin.”

This is anatomically impossible, unless the flexed middle finger enters the rectum – surely they don’t mean that! – and even then it would be a stretch to reach the chin. Something probably got lost in translation. In practice it’s likely that midwives using the Care Bundle controlled delivery of the head by perineal pressure and discouraging maternal pushing.

I confess I feared the whole study would shed more heat than light on the topic, and together with a colleague, Hannah Dahlen, wrote a grumbling opinion piece (click here).

But the results are in (click here or gurol-urganci), together with a qualitative study of the implementation process (click here or bidwell), and I’m eating my words.

The study was registered (click here), and the protocol published (click here). Registration was a bit late 22/09/2017 – the project ran from 1 October 2016 and 31 March 2018 – but that’s made clear in the paper, and the protocol had been publicly available since January 2017. There’s no reason to believe either was written after peeking at the data.

Four regions, each containing a mixture of different size and type of birth unit were studied over the same 18-month period, with routine data collected all through. Only four randomised units is rather few, but unavoidable due to funding contraints.

Regions were randomised to have the care bundle taught and implemented sequentially over months 4-6, 7-9, 10-12 or 13-15 respectively. These transition periods were excluded from analysis. This left four 3, 6, 9 or 12-month duration baseline phases, and four same duration evaluation phases to compare. The Consort flow diagram, for some reason relegated to supplementary material* (click here), shows the design nicely. Exclusions were all for objective reasons, Caesarean, multiple or still-birth and did not alter over the trial.

All women having a singleton vaginal birth were included and the size of the before and after groups was approximately equal (baseline 27,668, evaluation 27,932). This is reassuring. Differential rates of Caesarean birth, baseline 12,807 (31.6%) v evaluation 12,472 (31.3%), had not muddied the waters.

The primary, indeed the only, endpoint was OASI (obsteric anal sphincter injury) as recorded on the hospital routine database, and the primary analysis was done after statistical adjustment for a range of potentially relevant factors. Here are the relevant methods as reported in the paper.

“We used multi-level logistic regression to estimate adjusted odds ratios (aOR) […]. The regression model included a linear term for calendar time […] a random effect to account for clustering at both region and unit levels and individual case-mix factors (maternal age, ethnicity, body mass index, parity, mode of birth and birthweight).”

And here they are as planned in the protocol.

“We will use logistic mixed effects regression to model the log odds of sustaining an OASI, with a fixed effect for each step and a random effect to account for clustering at the unit level. The model will include a linear secular trend and also adjust for risk factors for OASI (maternal age, BMI, ethnicity, mode of delivery, episiotomy, birthweight, prolonged labour, and shoulder dystocia).”

Perfect. The planned analysis was done.

And the result. The recorded OASI rate decreased from 911/27,668 (3.3%) baseline phase to 817/27392 (3.0%) evaluation phase (aOR 0.80, 95% CI 0.65–0.98) p=0.03.

But what does it mean? Did manual perineal protection prevent 94 women suffering OASI? Did the 60o episiotomy do the trick? Did a few women read the leaflet and, fearful of OASI, choose Caesarean? Or a mixture of all three? Or was the difference in the “diagnosis” of OASI?

The original research, which had inspired the trial, had shown a much larger increase in recorded OASI from 1.8% in 2000 to 5.9% in 2011 (click here). The authors of that study, who included many of the current trial authors, had concluded that “improved recognition of tears following the implementation of a standardised classification of perineal tears was the most likely explanation”. They were surely correct. Diagnosing OASI is not easy. It can be both over and underdiagnosed. An effect size of 0.3% in an endpoint which can vary by 4.1% due “improved recognition” must be susceptible to ascertainment bias.

And this was an “open” trial. Staff may not have realised they were in the baseline phase but they certainly knew about the implementation and evaluation phases. This is from the qualitative study report (click here or bidwell).

“Many participants spoke about a well advertised launch, which created a lot of ‘noise’ and got the project off to a good start: ‘Yes, we had a launch day at the unit….on that day they had many sessions talking about it. We had the models.….they had pictures of how you would give an episiotomy, things like that, to add to this…There was quite a lot of noise about this. (Midwife)'”

“Many talked about the positive and passionate way with which the champions delivered the training. ‘She [the champion] was like a hound! …. if you weren’t trained and you were on her list, she would hunt you down….She would come in early to catch people on night shifts and stuff……If you have somebody like that who is passionate about the training and gets the training done, then I think that’s what makes it better. (Obstetrician)'”

How did midwives and doctors in the midst of such a campaign classify borderline cases?

Consider, for example, a woman with suspected OASI transferred to the operating theatre for repair, who when reviewed under good light by a senior staff member was found to have an intact sphincter? Would the theatre staff recode the planned operation to “repair of episiotomy”? In the baseline phase they might not even have realised the diagnosis had changed. But in the implementation and evaluation phases, with champions “hounding” everyone, the coding surely would be altered. Of course the effect might also have gone in the other direction. Routine rectal examination might have increased diagnosis. We just don’t know.

These doubts matter because the underlying evidence base for each component of the bundle is so weak. Well designed individually randomised trials do not support manual perineal protection (click here), there have been no trials of 60o angle episiotomy, and rectal examination after normal birth in the absence of a tear makes no sense (click here).

We can all support information giving, avoiding midline episiotomies and doing rectal examinations in the presence of tears. But the debate over manual perineal protection, extremely lateral episiotomy, and routine rectal examination even after normal birth with an intact perineum, will surely continue.

An improved martini

September 4, 2020

Not a better recipe, but a better technique – freezing water in the glass

Last week, dipping into Kingsley Amis’s Everyday Drinking (click here) on holiday, I came across this under “the Dry Martini”.

“A couple of hours before the party get your glasses together. They should be on the small side – the second half of a too large martini will have become too warm by the time the average drinker gets to it – and have some sort of stem or base to prevent the hand-imparting warmth. […] Fill each with water and put in the refrigerator.”

I read it as “put in the freezer”. As Amis says.

“It is more important that a cold drink should be as cold as possible than that it should be as concentrated as possible.”

I should have realised that in Amis’s day the freezer section of a domestic fridge would barely hold a tray of ice; no chance even a small martini glass. But I’ve got a modern monster freezer, so undaunted I made my martini. Freezing the water in the glass in emulation, and using a modern vermouth, Regal Rogue – Daringly Dry (click here), to annoy him. Click here for the video. It worked a treat.

    

Only afterwards did I realise he’d never meant “freeze the ice in the glass”. He wrote.

“While the jug is standing, empty the water out of the glasses and drop a bit of lemon rind in each.”

Nor, from a brief google search, does anyone else. People add ice cubes, sometimes large ones to avoid the over-dilution problem, but never my technique.  I offer it to the world.

Jim Thornton

6 September update

I was wrong, or rather right first time. Amis did advocate freezing water in the glass, albeit ten years later. My volume is a compendium of three books; On Drink (1974), Everyday Drinking (1983) and How’s Your Glass? (1985). The quotations were from On Drink. By the time of Everyday Drinking he must have got a larger freezer. He writes.

“The best Dry Martini known to man is the one I make myself. In the cold part of the refrigerator I have a bottle of gin and a small wineglass, half full of water that has been allowed to freeze.”

“When the hour strikes I half fill the remaining space with gin, flick in a few drops of vermouth and add a couple of cocktail onions, the small white hard kind. Now that is a drink.”

Oh well. Nothing new.

Lockdown cocktails

July 13, 2020

Drinking – not paddling – down the Loire

Our small gang have been walking the Camino de Santiago (click here or here), and more recently canoeing the Loire (click here or here). When lockdown put paid to our 2020 trip from Blois to Saumur we met up on Zoom instead, and inspired by Stanley Tucci (click here and here), drank cocktails. Here they are; some with a poem.

Hemingway’s daiquiri (click here).

Philip Larkin’s gin & tonic (click here).

A “No”groni (click here).

A conventional Negroni under adverse conditions (click here).

James Bond’s Vesper martini (click here).

The Gilles Villeneuve martini (click here).

A Radish Walked into a Bar (click here)

The Kingsley Amis martini (click here).

Forgive the rough edges. Filmed on different phones, and once made you’ve gotta drink it, so a second take wouldn’t help.

We also drank appropriate wine from the brothers Yapp, but no videos of that. First day sweet Vouvray (click here), 2nd a dry one (click here), 3rd Bourgueil (click here), 4th Saint-Nicolas-de-Bourgueil (click here) and 5th Saumur (click here). Forgotten the others, but to end with, we popped open a fizz (click here). All more expensive than our usual riverbank plonk, but I guess we’d saved on the ferry crossing.

Wild swimming in the river Trent.

June 6, 2020

Downstream of Nottingham

One of my projects for the 2020 lock-down summer has been to swim the best spots. If you don’t mind disclaimer forms, safety briefings, and signing in and out [1], there’s a dedicated centre on Colwick Park lake (click here). But that’s not for me. For swimming spots in the gravel pits click here.

These swims are for privateers. All, bar Farndon, are on the left, northern, bank. I’ll try to remedy that in any updates. Update 16 June – Cromwell.

Stoke Bardolph

Right in front of the Ferry Boat pub, two or three slipways and landing stages provide easy access. Great spot. Crowded on sunny days.

  

It’s also about 100 yards upstream of the discharge from Severn Trent’s, state of the art, Stoke Bardolph treatment plant! Ideal if you’re nervous of pollution.

Gunthorpe

Park in front of the Unicorn Hotel, and swim off the metal boat ramp next to the water ski club.

      

Don’t forget Gunthorpe gravel pit. Some fishermen claim swimming is prohibited there, so be discreet. Walk under the road bridge for about 1/2 mile, and turn right immediately after footbridge. Lots of easy access and a lovely stony bed. Magical.

 

Hoveringham

On sunny days the parking along the river bank road gets full early, but the bank is stony and access easy. Any slight smell is from muck-spreading on the surrounding fields, not the river. Another good spot.

Hazleford

One of my favourites. The metal slipway at the end of the road provides easy access, albeit slippery. The car park is private and locked, but there’s plenty of space on the road. The boat moorings leave a sheltered area near the slipway for those who are nervous of venturing into midstream.

If the slipway’s crowded try upstream, along the river path, past the moorings and caravan park. Plenty of the fishing pegs have good access. I swam by the Km 23 mark.

Downstream is less good. Although there’s plenty of access points below the weir, the water tends to be frothy.

   

Fiskerton

Park about 1/4 mile downstream of the Bromley Arms and walk upstream. The problem here is the high river wall. Don’t even think of jumping! Some pontoons are barred off, and they all have “private mooring” signs, but no-one has ever objected to me using one of the open ones. Getting back on is tricky. Swim round to the river wall – shallow stony bed – and step back on with your dignity intact.

        

Peg 18 below Fiskerton

Park as above and walk downstream. Nottingham Piscatorial Society have marked their fishing pegs with numbers set in the grass. Peg 18 is obscured but it’s the best spot. If you avoid the fishing season, usually quiet enough for a skinny dip.

 

Farndon

From the roundabout at the south end of Newark bypass, take the B166, the old Fosse Way to Farndon. Turn right, then left, initially following signs to Farndon marina. Then ignore the 2nd right to Farndon marina and follow signs to The Waterfront. Sandy ramp. Lovely.

North Muskham

Down Ferry Lane to the Muskham Ferry pub, and swim off the slipway. Slightly muddy, but nothing to trouble a wild swimmer.

  

Cromwell

A farm track, signed as a footpath, from Cromwell village, crosses the A1 as a single track road to the lock. Plenty of parking at the sign which says “no parking or boat launching at the lock”. Upstream of the lock, by two brick barbeques, a ramp leads to a pontoon with steps into the water at each end. Perfect.

           

Carlton-on-Trent

Head for the Church, and Ferry Lane. The road to the river, Perry Lane, is full of “no access to river” signs so I parked back up in the village. In fact there is parking. Two possible swim spots. Upstream of the commercial wharf, access looks easy via stony muddy banks, but I was nervous of a metal detectorist on the opposite bank.

The wharf itself has a ladder down to the water, but it’s high and muddy and my courage failed again. About 1/4 mile downstream is best. Stony and a bit muddy, but a good gap in the nettles. The opposite bank also looked inviting.

Carlton is downstream of Cromwell weir, so right at the tidal limit. But it’s on the outside of the bend so you’re straight into fast flow. I kept station, but only just. If you got carried downstream, you’d end up clambering out through nettle beds.

   

I’ve never swum below Carlton. There must be good spots but I doubt they beat the ones above.

Footnote

  1.  One of the annoyances of river swimming is people banging on about the risks. Learn to swim and avoid the river in spate or near weirs. Weil’s disease is rare; only about 30 recreational cases, and less than one death, per year in the UK. Given the number of people coming into contact with river water, the drive to the riverbank is probably more risky, but avoid swimming with an open cut. Gastroenteritis is less of a risk for older swimmers who don’t wear wet suits; we don’t stay in so long, have developed antibodies and are wise enough not to swallow.

Covid-19 in Pregnancy; scientific studies

May 15, 2020

Primary clinical sources. Updated 14th April

In roughly reverse order. Updated regularly. Click here for ripe-tomato.org’s Covid-19 in pregnancy navigation page.  Curated by Jim Thornton, Keelin O’Donoghue & Kate Walker.

Ongoing update rules. Studies added in the order in which we find them. Study numbers never change. Inadvertent duplicates deleted. Each study report contains a link to original report, pdf, and full citation. Country, state and city recorded only once for ease of counting.  From February 1st 2021 we will selectively report laboratory studies of stored specimens such as sera and placentae. Such studies are important, but unless they also purport to report original clinical data, there is less need to note duplicate reporting.

Occasional [important] studies include early series, reliable registries, high-quality therapeutic trials in pregnancy (none yet), or basic science

Study 310 – 86 pregnant women treated with remdesivir

Of the first 86 pregnant, or recently pregnant, women with severe Covid-19 (O2 satuation <=94%), treated with compassionate use remdesivir (all outside a trial) between March 21, & April 22nd 2020, 63 were admitted to ICU, 45 required ventilation and one ECMO (click here or ciaa1466). One woman died. At 28-day follow-up seven women were still being ventilated (appendix Fig 2 ciaa1466_suppl_supplementary_materials_1 (1)).  Among 45 deliveries there was one 17 weeks miscarriage but otherwise no babies died. Four women were treated in Spain, two in Switzerland and one each in Italy and the UK. The rest were from the United States. Many have presumably been included in other reports.

Study 281 – First report from the US PRIORITY Study 

The PRIORITY study collected self-reported cases of Covid-19 in pregnancy. In this report they describe the outcomes of 179 infants born to mothers who had tested positive and 84 who tested negative. 82% of the former group and 63% of the latter had symptoms (click here or ciaa1411). 44 babies were admitted to NICU, and two were infected. Although not explicitly stated there appear to have been no stillbirths or neonatal deaths. Births occurred at over 100 hospitals across the US so it is likely that many will have been included in other US reports.

Study 271 – 86 “extra” maternal deaths during pandemic in Mexico

These authors used publicly available goverment statisitics (click here) to estimate the excess maternal deaths from Covid-19 in Mexico in 2020 (click here or Excess_Maternal_Deaths_Associated_With_Coronavirus.97254). The predicted maternal mortality ratio was 29.5 per 100,000 live births, and so far in 2020 the actual ratio is 42.4. The excess was entirely confined to respiratory disease. Overall 86 “extra” deaths have ocurred. In comparison the 168 deaths officially reported as due to respiratory disease are made up of 109 deaths due to confirmed COVID-19, 34 for which COVID-19 needs to be confirmed, and 25 due to other respiratory diseases.

One mother with severe disease recovered. Another required ECMO and remains on ventilatory support at a tertiary centre three months following delivery at 30 weeks. All neonates were isolated, and one tested positive but was asymptomatic. No babies died. All authors were affiliated with McGovern Medical School at The University of Texas.

Three babies were stillborn. This is the first report from the Spanish “Obs Covid registry” which includes 77 hospitals. The patients are therefore likely to include some from previous Spanish series, namely studies 53, 125, 151, 158, 165, 185, 191, 196, 235, and 266.

Study 263b – 66 cases (plus one maternal death) from Tehran, Iran

Of 66 women with Covid-19 treated between March 1 to Sep 1, 2020, four were admitted to ICU but none required ventilation (click here or taaa158). Two women aborted, 43 delivered, and 21 pregnancies are ongoing. No baby outcomes are reported directly, although one baby tested positive. No women in the series died. However in the discusssion section it is mentioned that in February 2020, a 22-year-old pregnant woman with COVID-19 at 37 weeks had died in the same hospital. It is not clear if she had been included in studies 23, 66 or 67. The women were cared for in Arash Women’s Hospital, which has also reported a set of triplets of which one was infected with SARS-CoV-2 and survived, and the other two who were negative died, (case 5 in study 250).

Ten women died with SARS-CoV-2 between 01/03/2020 and 31/05/2020, seven directly due to Covid-19, one cause not determined, and two due to unrelated causes (click here or Ref.-201-MBRRACE-UK-maternal-COVID-19-Report-FINAL (002)).  Six further women died by suicide or domestic violence, conceivably related to lockdown, over the same period. They overlap with those in studies 29, 52, 68, 92, 107, 126 & 200.

Study 254 – Breast milk testing in 18 affected women from the USA

Eighteen women with SARS-CoV-2, 17 symptomatic, had multiple breast milk samples tested (click here or jama_chambers_2020_ld_200087_1597789061.40481). One sample had detectable SARS-CoV-2 RNA, but no replication-competent virus was detectable in any sample, including the sample that tested positive for viral RNA. The samples were collected from woman anywhere in the United States so may include cases previously reported. Citation: Chambers C, Krogstad P, Bertrand K, et al.

Study 253 – Case report from China

A woman with Covid-19 was delivered at 35 weeks gestation by caesarean section (click here or 1-s2.0-S1876034120304391-main). The baby was not infected. From author affiliations the unnamed hospital was probably Chongqing Three Gorges Central Hospital (grid.477128.f) which has not previously reported cases.

Study 252a – Case report from Italy

An asymptomatic woman with SARS-CoV-2 underwent Caesarean for breech at 38 weeks gestation (click here or medicina-56-00306-v2). The baby was asymptomatic and tested negative. Swabs from the amniotic surface of the placenta were positive. The hospital was IRCCS Ospedale Policlinico San Martino, Genoa, which has not previously reported cases.

Study 252 – 49 new cases from Italy

These 49 women with SARS-CoV-2 in pregnancy were collected between 10–26 April (click here or 10.1080@14767058.2020.1788532).  No outcomes reported. The unnamed hospitals in Milan and the six provinces of Lombardy (Brescia, Como, Lecco, Monza, Pavia, and Sondrio) were probably Sacco (Milan), Mangiagalli (Milan), S. Gerardo MBBM Foundation (Monza), Papa Giovanni XXIII (Bergamo), and San Matteo (Pavia) and the hospitals of Padua, Florence, Lecco, Trento, Modena, Seriate and Piacenza. However the recruitment period was later than that in studies 33, 64 & 117, so these patients have not been previously reported.

Seven mothers were admitted to ITU, and 2 intubated, but none died. Two babies were stillborn and five tested positive. There were no neonatal deaths. These patients likely overlap with those in studies 32, 64, 76, 79, 109, 114, 188 and 197. They probably do not overlap with those in study 195.

Study 245 – 141 cases from India

Out of 141 women with Covid-19 in pregnancy there were 3 abortions, one ectopic pregnancy and 3 maternal deaths (click here or Nayak 13224_2020_Article_1335). There were 3 stillbirths and 3 babies tested positive.

Study 244 – 125 cases from Turkey

Of 125 pregnant women with Covid-19 (click here or Oncel2020_Article), 7 mothers required ventilation and 5 died. Four babies tested positive and one (who tested negative) died. The babies were cared for in 34 unnamed neonatal intensive care units. From author affiliations these probably include İzmir (3 centres), İstanbul (6 centres), Rize (1 centre), Ankara (4 centres) and Kocaeli (1 centre).

Study 235 – 125 anti-SARS-CoV-2 sero-positive women from Spain

Of 874 pregnant women attending first trimester screening (n=372) or delivery (n=502) from April 14 to May 5, 2020, 125 were positive for anti-SARS-CoV-2 IgG, IgM, or IgA. 54/372 in first trimester, and 71/502 in 3rd trimester (click here or PIIS0140673620317141 & supplementary material mmc1). Three women required oxygen therapy, but none critical care. No baby outcomes reported. Women were cared for in Hospital Sant Joan de Déu, Hospital Clínic, and Sant Pau all in Barcelona.

Of 675 pregnant women admitted for delivery and tested for SARS-CoV-2, 70 were positive, of whom 55 were asymptomatic on presentation (click here or 1471-0528.16403). Three mothers were hypoxic, one was admitted to ITU but none required ventilation. No mothers died. There was one stillbirth to a mother with asymptomatic Covid-19 and other pathology. 73 babies were born, 71 were tested and all were negative. The three hospitals, were Weill Cornell Medical Center, Queens, and Lower Manhattan Hospital. The cases may therefore also have been included in studies 160, 216 and 230. However, they were probably not included in the other NY Presbyterian series namely studies 14, 27, 41, 95, 96 and 136.

Study 233 – case report from Morocco

A woman contracted Covid-19 at 31 weeks gestation, required oxygen therapy and went into premature labour. A Caesarean was performed for fetal distress (click here or 8852816). The mother recovered. The baby tested negative but had severe birth asphyxia and died age 5 days. The mother was cared for at University Hospital of Mohammed VI, Marrakech, which has not previously reported cases. This is the first report from Morocco.

Study 232 – 44 cases from US

Of 44 pregnant or recently postpartum women with COVID-19, 5 had severe disease and 2 required ventilation (click here or ijgo.13333). All mothers survived. Of 11 babies born, 9 tested negative and 2 declined testing. All survived. 31 pregnancies are ongoing. The majority of patients belonged to racial [sic] or ethnic minority groups.

Study 231 – 19 placentas from USA

2/19 placentas of affected pregnancies tested positive for SARS-CoV-2 by in-situ hybrization (click here or s41379-020-0639-4). There were no specific pathologic features compared with 262 control placentas. One fetus was stillborn at 22 weeks and not tested. There were two sets of twins. All liveborn babies survived, and only one tested positive. From the case codes in Table 2 it appears that 10 pregnancies had been cared for at Massachusetts General Hospital, 4 at Brigham and Women’s Hospital & 5 at Beth Israel Deaconess Medical Center, Boston. Some have therefore probably been reported in studies 129 & 142Citation: Hecht, J.L., Quade, B., Deshpande, V. et al. SARS-CoV-2 can infect the placenta and is not associated with specific placental histopathology: a series of 19 placentas from COVID-19-positive mothers. Mod Pathol (2020). https://doi.org/10.1038/s41379-020-0639-4

2/53 placentas from affected pregnancies contained a SARS-CoV-2 viral signal by in-situ hybridization (click here or Zhang, Placenta, AJOGMFM). One baby tested positive, the other negative. Both were asymptomatic. There were no specific histological differences between 74 placentas from SARS-CoV-2 positive pregnancies and 290 controls. The authors are affiliated with the New York Presbyterian, Brooklyn Methodist, Weill Cornell group of hospitals so the clinical aspects of the cases have probably been reported before.  Citation: Zhang P, Heyman T, Salafia C, Dygulska B, Lederman S, Detection of SARS-CoV-2 in placentas with pathology and vertical transmission, American Journal of Obstetrics & Gynecology MFM (2020), doi:  https://doi.org/10.1016/j.ajogmf.2020.100197.

8 August update – studies 225 to 229 added

Study 229 – Some assisted reproduction pregnancies during the pandemic in France.

The authors report 88, or possibly 104, women (numbers are unclear) who conceived by assisted reproduction between December 2019 & March 2020, and were still pregnant after the first reported case of Covid-19 in France on 12th February. Ten had symptoms related to Covid-19, none severe or requiring intensive care (click here or PIIS0301211520304929). Five of the ten were tested and two were positive. 15 women miscarried although their Covid-19 status was not reported. From author affiliations the unnamed centre was probably the Reproductive Biology UnitAntoine Béclère Hospital, Clamart. These cases may therefore feature in studies 150, 157, 184 & 217. The pregnancies were unlikely to have been sufficiently far advanced to have featured in studies 48 & 187.

Study 228 – case report from USA

A pregnant woman contracted severe Covid-19 requiring ventilation at 32 weeks (click here or Ching Case Rep RespMed). She was delivered by Caesarean section for suspected placenta praevia and recovered. The baby required intubation and ventilation for 48 hours but tested negative. The ultimate baby outcome is not reported. The hospital is unnamed but the authors’ affiliation with San Joaquin Critical Care Medical Group, suggests that it was San Joaquin General Hospital in Stockton, California which has not previously reported cases.

Study 227 – case report from USA

A woman with mild Covid-19 gave birth to a male infant vaginally at term (click here or HSU jmv.26386). She recovered. The baby breast fed, tested negative and was fine. The virus was demonstrated in the placenta by immuno-histochemistry using a  SARS-CoV-2 nucleocapsid-specific monoclonal antibody. Mother and baby were cared for at University of Missouri Women and Children’s Hospital Columbia, Missouri, which has not previously reported cases. The clinical details of case 69 differ.

Study 226 – 3 cases treated with remdesivir from USA

Three pregnant women with Covid-19 were treated with remdesivir outside a clinical trial (click here or PIIS0002937820308292). One developed “transaminitis” – I think the authors mean raised liver transaminase. The pre-print is missing a table – which the authors attributed to the remdesivir. That woman later developed intrahepatic cholestasis of pregnancy and delivered normally. The other pregnancies are ongoing. The acknowledgements suggest that the unnamed hospital is Lucile Packard Children’s Hospital at Stanford, California. Although one author is shared with study 115 from another unnamed Stanford hospital, the clinical details differ. These cases have probably not previously been reported.

Study 225 – over 600 cases (412 births) in India

Nair hospital, Mumbai, a dedicated Covid-19 facility, has cared for over 600 pregnant women with the disease (click here or ijgo.13338). There have been 412 births including seven pairs of twins and one set of triplets. No mothers died of Covid-19 directly, although four died of other causes. No baby outcomes reported. The first two cases had originally been cared for elsewhere, and also previously denied admission at four private hospitals, the latter a feature of news reports from India (click here). Two health care workers contracted COVID-19. Nair Hospital has not previously reported cases. The case reported in study 58 was from New Delhi.

Study 213 – 89 cases from Brazil

Of 89 women with Covid-19 cared for in a single institution between March 12 & May 25, 2020, the details of five who experienced a fetal death are reported (click here or 1-s2.0-S2214911220300734-main). No details of the other cases, and no explicit maternal outcomes are reported, but enough details are given for it to be implied that the mothers survived. From author affiliations the unnamed hospital is probably Hospital e Maternidade Santa Joana, São Paulo. Apart from study 194 which was from a different city, all previous reports of Covid-19 in pregnancy from Brazil (studies 66, 138, 182 & 201) have been of maternal deaths. These cases have therefore probably not previously been reported.

Study 212 – 2 cases from China

There were only two pregnant women with Covid-19 in Yichang city between January 20 & April 9, 2020 (click here or Coronavirus_disease_2019__COVID_19__in_pregnancy_.126). Both mothers and both babies survived. Neither baby was infected. The hospital was Yichang Central People’s Hospital. On GRID.ac this disambiguates as Peking University People’s Hospital grid.411634.5 which is probably an error. Yichang city is in Western Hubei province about 200 km west of Wuhan, and about 1000 km south of Peking/Beijing. Yichang city was a centre in study 57, so these two cases were probably included in that series, Citation: Zheng, Tingting; Guo, Jianqiang; He, Wencong; Wang, Hao; Yu, Huiling; Ye, Hong.

One twin was stillborn and the other died soon after birth. Amniotic fluid and placental tissue tested positive for SARS-CoV-2. From author affiliations this was probably Sint-Trudo Hospital in Sint-Truiden, which has not previous reported cases. Citation: Pulinx, B., Kieffer, D., Michiels, I. et al.

Study 192 – Case report from Zhongshan, in Guangdong Province, China.

A mother with Covid-19 at 35 weeks gestation suffered from a cytokine storm, and required both ventilation and ECMO (click here or Wang 1-s2.0-S0002937820307286-main). She survived, but the baby died. As the authors note this case was included in Study 3. The hospital, mother’s age, gestational age and baby outcome all suggest she is also the same woman as in studies 57 and 81.

Study 191 – 27 cases from Spain

This preprint reports 27 pregnant women with COVID-19 of whom seven developed some features of HELLP syndrome (click here or 2020.07.10.20133801v1.full). The details are difficult to interpret but I think 12 delivered, 5 by Caesarean, and no mothers or babies died. The patients were cared for in two unnamed hospitals which from author affiliations were probably Hospital de la Santa Creu i Sant Pau and Hospital Sant Joan de Deu, both in Barcelona. These hospitals have not previously reported cases under their own names. However, the patients may have been included in the Spanish Covi-Preg registry study 151.

Study 188 – Four, possibly five, cases from Italy

Four pregnant women with Covid-19 and a further woman who had possible pneumonia one day after delivering twins and two months later had SARS-CoV-2 IgG antibodies, are reported (click here or 10.1080@14767058.2020.1791817) All mothers and babies survived although one of the four definite Covid-19 mothers developed Guillain-Barré syndrome and remains in hospital. All patients were cared for Bolognini Hospital which is a “spoke center” for COVID 19 in pregnancy in Seriate, Bergamo in Lombardy. It is thus likely that they were included in studies 32, 64 & 117.

Study 187 – Case report of neonatal infection from France

A woman contracted Covid-19 at 35 weeks, required Caesarean for fetal distress, and recovered with supportive treatment (click here or s41467-020-17436-6). The baby was initially well but developed neurological symptoms on day 3. Maternal nasopharynx (NP), blood, placental, vaginal and amniotic samples were all positive for SARS-CoV-2. Baby blood and rectal samples, as well as NP samples on days 1, 3 and 18, were also positive. The baby recovered with supportive treatment. From author affiliations the hospital was Antoine Béclère, Paris. Although not cited, this is case two in study 48. The papers share two authors, Alexandra J Vivanti & Alexandra Benachi, from the same hospital, and all reported maternal and baby characteristics, as well as all the mother’s blood values on the day of birth, are identical.

The fetuses of two pregnant women with Covid-19 developed transient skin oedema at 21 and 25 weeks gestation (click here or Fetal_Transient_Skin_Edema_in_Two_Pregnant_Women.97307). One mother, cared for at Vall d’Hebron University Hospital in Barcelona, had severe disease requiring ventilation. The other, hospital not stated, had mild disease only. Amniotic fluid was negative for SARS-CoV-2 in both cases. Both resolved and the pregnancies are ongoing. The Barcelona case at least was probably included in study 140.

Study 184 – 100 cases from France

One hundred pregnant women with Covid-19 were treated in four Paris hospitals between March 12 & April 13, 2020 (click here). Ten were admitted to ICU of whom 9 required intubation. There were no stillbirths or miscarriages, but one neonatal death due to prematurity. All neonates were tested for SARS-CoV-2. One was positive but did not show signs of respiratory illness. The hospitals were Antoine Béclère, Clamart; Bicêtre Hospital, Le Kremlin Bicêtre; Louis-Mourier, Colombes; and Centre Hospitalier Sud Francilien, Evry. They therefore include one of the cases in study 48, are included in study 150 and probably also overlap with those in study 157.

Study 161 – 54 cases from France

Of 54 pregnant women with confirmed (n=38) or suspected (n=16) COVID-19 in pregnancy treated at Strasbourg University Hospital from March 1 to April 3, there was one miscarriage, 21 live births (12 vaginal, 9 cesarean), and 32 ongoing pregnancies (click here or PIIS0002937820306396). Five women were admitted to ICU, three required mechanical ventilation and one ECMO. No mothers died, although at the time of writing the woman on ECMO remained on it. All babies tested negative & none died. Strasbourg doctors co-authored the GROG report, so these cases are probably included in study 150.

18 June update – studies 157-160 added

Study 160 – 241 cases from USA

Of 241 pregnant women with laboratory-confirmed SARSCoV-2 infection who gave birth between March 13 & April 12, there were 245 live births to 241 women (6 sets of twins), & 2 stillbirths (click here or Characteristics_and_Outcomes_of_241_Births_to.97310). 17 women were admitted to ITU and 9 intubated. No mothers died, although one woman remained intubated at time of writing. 27% of neonates were admitted to NICU. Of liveborns with SARS-CoV-2 test results 236/230 tested negative. No further neonatal outcomes reported. The five hospitals were “Montefiore Medical Center; Mount Sinai Health System, including Mount Sinai Hospital and Mount Sinai West; its affiliate, NYC Health and Hospitals- Elmhurst Hospital; NY-Presbyterian Hospital- Columbia University; and NY University Langone Health, including NYU Langone Hospitals, Manhattan campus, and NYU Langone Hospitals-Brooklyn”. These cases therefore likely overlap with studies 14, 27, 41, 49, 83, 85, 86, 95, 95, 119, 135, 136, & 152. They probably do not overlap with women in studies 61, 113, 118, 122 & 134, which included women cared for in different centres. Women in Study 99 are unclear.

Study 151 – 82 cases from Spain

Of 82 women with singleton pregnancies and Covid-19, who delivered within 14 days of disease onset, collected from from 96 maternity hospitals, 9 were admitted to ICU and 7 ventilated (click here or jama_martnezperez_2020_ld_200062). Five babies tested positive. No mothers or babies died. The hospitals are not named but author affiliations include Puerta de Hierro University Hospital, 12 Octubre University Hospital, & Gregorio Marañon University Hospital, all three from Madrid.

Study 150 – 617 cases from France

Thirty three maternity units from the “Groupe de Recherche en Obstétrique et Gynécologie (GROG)” treated 617 pregnant women with COVID-19 between March 1 & April 14 (click here or GIlles France JOG HR). Eighty three women required nasal oxygen, a further 10 non-invasive ventilation, a further 29 mechanical ventilation and a further six, ECMO.  One woman died. There were 5 miscarriages and 7 stillbirths among the 181 pregnancies which had ended. Among the 190 live births (7 twins & 1 set of triplets) there was one neonatal death. Two babies tested positive. The 33 maternity units (including 24 tertiary referral centers) are not named, although 19 can be guessed from the author affiliations.

6 June update – study 149 added

Study 149 – 73 cases, 8 severe, from USA

Of 73 pregnant women with COVID-19, 31 were admitted, of whom 8 visited ICU. Of these 6 needed intubation, and 1 ECMO (click here or 1-s2.0-S2589933320300951-main). 7 of the 8 ICU cases were delivered by Caesarean and one remains undelivered.  All babies were isolated and fed artificial or donor milk. All tested negative. All mothers were discharged from intensive care. No babies died but four remain in hospital. No details given of the non ICU cases. The “network’s two largest hospitals” in which the patients were treated are not named. The authors are affiliated with three large hospitals in New Jersey  Hackensack University Medical Center, University Hospital (Newark, New Jersey) and Hackensack Meridian Jersey Shore University Medical Center. The patients are therefore probably different from those reported in Studies 86, and 111.

Study 148 – 29th May ICNARC report

The 29th May ICNARC update (click here or ICNARC COVID-19 report 2020-05-29.pdf) contains 23 currently, and 34 recently, pregnant women critically ill with Covid-19. Of these 10 and 20 respectively had received advanced respiratory support.

Study 147 – 223 cases from the Netherlands

The 5th June  update of NethOSS (click here), accessed 4 June 2020, contains the following. 6/210 women with brief additional details were admitted to intensive care. One mother died. 66 women have given birth, 25 by Caesarean. 142 pregnancies are ongoing. No baby has died. No babies were infected. Citation: See Studies 42, 46, 120, & 141. Available here.

Two pregnant women with Covid-19 were delivered by Caesarean at term, one miscarried at 7 weeks and five pregnancies are ongoing (click here or jum.15367).  One delivered baby tested negative. No details are reported of the other. All mothers recovered. The tertiary hospital is not named, but from author affiliations is probably Sehit Prof Dr Ilhan Varank Sancaktepe Training & Research Hospital, Istanbul. These case are therefore unlikely to overlap with those in Studies 31 and 145. Citation: Yassa M, Birol P, Mutlu AM, Tekin AB, Sandal K, Tug N.

Twelve women with COVID-19 were admitted for delivery between February 26th & to April 3rd 2020 (click here or kja-20204). Four birthed vaginally and 8 by Caesarean. Two babies were stillborn. All patients were cared for at Daegu Fatimal Hospital, (see Study 22 cited in paper). Although there is no explicit statement about whether the patient in Study 22 was included, the clinical details (age and gestation) differ, so it is likely that all 12  have not previously been reported.  Citation: Jeongmin Oh, Eunju Kim, Hyunkyum Kim, Sang-Ah Lee, Kyeong Hee Lee, Mi Hyae Yu, Jihyun An.

Study 140 – 42 cases from Spain

Forty two pregnant women with Covid-19 between March 13 & April 10 (click here or 1471-0528.16339). Eight required admission to ICU of whom 6 developed some features of pre-eclampsia, 4 requiring Caesarean, one of which was due to HELLP syndrome. No maternal or baby outcomes are reported but it is implied “after recovery from severe pneumonia, hypertensive therapy was no longer required in all cases” that all women recovered. The “tertiary care” hospital is not named but from author affiliations is likely to be Hospital Universitari Vall d’Hebron, Universitat Autònoma de Barcelona. If so, these cases have not been previously reported.

May 6th update – study 79 (HT Shakila Thangaratinam) & studies 80 & 81 added.

Study 81 – Case report from China

A 31 year old woman developed Covid-19 at 35 weeks gestation (click here, or ijgo.13189). The mother’s condition deteriorated rapidly, requiring ventilation, and later ECMO. The baby was delivered by emergency caesarean but died within two hours. The mother survived. This is the second pregnant woman requiring ECMO reported from China. Zhongshan People’s Hospital disambiguates as grid.476868.3 and no patients from Zhongshan have previously been reported, not in Study 3, nor in studies 55 or 57. This case is therefore likely original. Citation: Li J, Wang Y, Zeng Y, Song T, Pan X, Jia M, He F, Hou L, Li B, He S, Chen D. Critically ill pregnant patient with COVID-19 and neonatal death within two hours of birth. Int J Gynaecol Obstet. 2020 May 5. doi: 10.1002/ijgo.13189.

Revised comment 7 May. The city of Zhongshan is in the province of Guangdong. Study 3, which initially mentioned “patient 6”, a 31 year old woman at 34 weeks on ECMO, whose baby had died, included one patient from Guangdong. Study 57 described a 32-year-old woman at 35 weeks from Zhongshan, Guangdong whose baby had died soon after birth. At the time of the report that woman had been weaned off ECMO but remained an inpatient. Despite the minor inconsistencies in maternal and gestational ages, it is likely that all three reports refer to the same woman. If so there has only been one pregnant woman with Covid-19, treated with ECMO, and reported from China. She survived.

Study 57. 116 cases from 25 hospitals in China

This preprint from Am J Obstet Gynecol (click here) includes 116 mothers with Covid-19 (65 lab confirmed, 51 clinically diagnosed), of whom 8 had severe disease. None died. 99 mothers had delivered 100 babies (one set of twins) of whom one died. This paper claims to be an “an expanded series that have included 33 published cases.16,18-20”. Their reference 16 is our Study 1, ref 18 is our Study 38 and ref 19 is our Study 6a.  Their reference 20 is as follows:  “Lei D, Wang C, Li C, et al. Clinical characteristics of COVID-19 in pregnancy: analysis of nine cases. Chin J Perinat Med 2020,23:doi: 10.3760/cma.j.cn113903-20200216-00117.” Although cited in a number of reviews we have so far been unable to find the original source. Update 18 December – see Study 511

The patients were collected from 25 hospitals within and outside Hubei province, between January 20 and March 24, 2020. Three recruiting hospitals, all from Wuhan, listed in the supplementary material, overlap with those in study 55 (appendix table s1). These are Zhongnan Hospital of Wuhan univerisity, the Central Hospital of Wuhan, and Tongi Hospital, all multiple reporters of Covid-19 in pregnancy. Thus it is likely that, in addition to the studies cited, this series overlaps considerably with Study 55. Not added to running totals. The patient requiring ECMO came from Zhongshan, Guangdong. She is probably the same woman reported as treated with ECMO from the city in Study 3. She survived.

16 April update. Studies 44 & 45 added. HT @Belinda_J_Lowe for study 45. We’ve also done some housekeeping today. Study 13 probably overlaps with study 1, so S13 has been removed from running totals. Study 3 includes 13 patients from multiple centres, both in and outside Hubei province, who may overlap with other studies. 12 mothers (3 undelivered) and 9 babies therefore removed from the running total. Only S3, case 6, woman on ECMO & baby stillborn & preterm, does not appear to have been reported elsewhere, so remains in the running totals.

These 33 women with Covid-19 delivered infants at the New York–Presbyterian Allen Hospital and Columbia University Irving Medical Center between March 22 & April 4, 2020 (click here). They presumably include the 18 women with Covid-19 previously reported as having delivered in the same two hospitals (Studies 14 & 27), as well as some of the women who were at the time undelivered in those two series.

Out of 41 pregnant women from the Maternal and Child Health Hospital of Hubei Province, with typical Covid-19 infection on lung CT, 16 were SARS-CoV-2 positive, 17 negative and 8 not tested. Nineteen were inpatients for delivery, and the rest outpatients from 22 weeks onwards.

However the series probably includes the 16 cases also reported from Remnin in Chinese (study 6a), which included the same number, three, preterm patients, all also delivered by Caesarean. They may also overlap with study 10; both studies mention two doctors delivered by Caesarean in Renmin. The obstetrican on study 36, Bi-heng Cheng, is shared with study 6a.

They were identified by searching the national database of 81,026 laboratory-confirmed cases up to March 13 using the same methods as in a study of infants age 1 month to one year reported in JAMA (click here but not listed in this blog post). It seems likely that they overlap with the three infected neonates reported earlier in JAMA (study 12), the case report in Clinical Infectious Diseases (study 11) or the infected neonate reported in Lancet Inf Dis (study 15).

6 April update. No new scientific reports today. But obstetricians & midwives will enjoy reading the first newspaper report of a Covid-19 pregnancy and birth in France. Case 10 here. Better written and more detailed than many scientific reports.

5 April update. Study 26 added. The first report of puerperal Covid-19. Not added to running totals.

Study 26. The first case report of puerperal COVID-19, China

This baby developed COVID-19 symptoms at age 10 days and was admitted to Wuhan Children’s Hospital age 17 days on February 5, 2020.  Click here for the article in Chinese. What follows is based on Google translate. Both parents are reported to have had Covid-19 symptoms from three days before admission, i. e. day 14 after birth. This is therefore not a case of COVID infection in pregnancy or at birth, and therefore excluded from the running totals. However, the mother had puerperal Covid-19 and is, I believe, the first such case reported. The baby recovered and by implication, albeit not stated explicitly, so did the parents. The first author Zeng Lingkong shares a name with the first author of the series of 33 neonatal cases reported in JAMA Paediatrics, Study 8., but this is clearly not one of the three infected babies reported in that paper.

Click here or who-china-joint-mission-on-covid-19-final-report for full text including annexes. (For Chinese version click here or who-china-joint-mission-on-covid-19-final-report chinese version. Annexe 6, page 32 of English version: “As opposed to Influenza A(H1N1)pdm09, pregnant women do not appear to be at higher risk of severe disease. In an investigation of 147 pregnant women (64 confirmed, 82 suspected and 1 asymptomatic), 8% had severe disease and 1% were critical.” Neither raw numbers, a citation, nor any further details are given. Assuming the percentages are of all 147, this would imply 12 women with severe disease, and one or two who were critical. In view of the high possibility of double counting – cases notified to the WHO team are likely to have also got reported elsewhere – I’ve left these out of the running total. Citation: Report of the WHO-China Joint Mission on Coronavirus Disease 2019 (COVID-19) 16-24 February 2020. Report submitted 28 February 2020

3 April update Studies 23 & 24 added. Study 23 is judged unreliable for reasons given below, and study 24 included no pregnancies. Neither have been included in the running totals.

Study 24. No SARS-COV-2 in vaginas of non-pregnant women with severe Covid-19

Although not a study of pregnancy, this report of ten women with confirmed severe COVID-19 pneumonia in Tongji Zhongfa Hospital, Wuhan, China (click here or ciaa375) is reassuring for vaginal birth. None were positive for SARS-CoV-2 by RT-PCR assay in vaginal fluid. Citation: Lin Qiu, Xia Liu, Meng Xiao, Jing Xie, Wei Cao, Zhengyin Liu, Abraham Morse, Yuhua Xie, Taisheng Li, Lan Zhu. SARS-CoV-2 is not detectable in the vaginal fluid of women with severe COVID-19 infection. Clinical Infectious Diseases, ciaa375,  https://doi.org/10.1093/cid/ciaa375

Study 23. Three cases from Iran

This review (click here, full text here) from researchers in both Tehran and Shiraz, includes a report of the births of three infants from infected mothers, apparently not previously reported. The authors’ source was this Iranian ministry website (click here). All three babies were uninfected and survived, but two of the three mothers developed acute respiratory distress syndrome (ARDS) after delivery and died; presumably related to their Covid-19 infection.

Comment by Jim. Although these cases are reported in a scientific journal, the source is a website. The authors do not claim to have treated either the women nor the babies. The women are said to have delivered in Mazandaran and Zanjan provinces. None of the authors give these provinces as their address.  A google translation of the link provided reveals a report of a single case of a woman with COVID-19 who delivered at 36 weeks in Babol. Mother and baby doing well. Again none of the article authors came from Babol. It seems likely that the source of these three cases is the website alone. We have therefore excluded them from our running totals.

1 April update

Study 6a added (details below).

30th March update

Study 17. Five from China

Two Caesarean and three vaginal births delivered in the Maternal and Child Hospital of Hubei Province, Tongji Medical College grid.412793.a (click here). Or siyu chen.  All mothers recovered. All babies well. According to Wikipaedia the MCH of HP is the 10th clinical college/hospital associated with Tongji Medical College. It is distinct from both Union hospital and Tongji hospital. These five births are therefore additional to those in the various Union Hospital reports, and to those in study 15. Citation: Chen S, Liao E, Shao Y. Clinical analysis of pregnant women with 2019 novel coronavirus pneumonia. J Med Virol. 2020 Mar 28. doi: 10.1002/jmv.25789. [Epub ahead of print] 

Study 16. Three non-cases from Shenzhen 2nd People’s Hospital.

Shenzen, a city of 13 million had had 420 confirmed cases of Covid-19, the second highest number outside Hubei, up to March 11th. Despite an annual birth rate in the city of 188,000, the 2nd People’s Hospital saw no COVID-19 infected pregnant women. Instead they report three suspected cases who, after barrier nursing, and in one case surgery for an ectopic pregnancy, were later confirmed negative.

29th March – 3rd update

Study 15. Seven cases from China

These seven cases (click here) delivered at Tongji Hospital, Tongji Medical College grid.412793.a, Huazhong University of Science and Technology, Wuhan, between Jan 1 and Feb 8, 2020. All mothers had mild Covid-19 disease and all were delivered around term by Caesarean section. One baby (Patient 1) tested positive for Covid-19 by throat PCR at 36 hours and was transferred to Wuhan Children’s hospital. His mother’s age, gravidity, parity, lack of direct contact with Hunan seafood market and history of hypothyroidism all suggest this is the same mother/infant dyad as in report 11. Note however the reported birthweights differ 3250g v 3205g. No babies had any clinical symptoms and all (including the transferred one) were discharged home well. Wikipedia lists ten different hospitals/clinical colleges affiliated with Tongji Medical College in Wuhan. The 1st clinical college is called Wuhan Union Hospital. The 2nd clinical college is called Wuhan Tongji Hospital. This series is therefore unlikely to overlap with the various case series from Union Hospital Tongji.

29th March update. Four more primary reports including ten more cases. All previously unreported.

Study 13. Cord blood serology from six babies in China

Six cases reported in JAMA (click here). All births by Caesarean in Zhongnan Hospital, Wuhan. All mothers mild disease. All babies asymptomatic. Since they were born in a different hospital these are probably additional to the other 33 Wuhan neonates reported in JAMA. Revision 16 April: These are from the same hospital as study 1 and may overlap. Therefore removed from running totals.  Citation: Hui Zeng, Chen Xu, Junli Fan, Yueting Tang, Qiaoling Deng, Wei Zhang, Xinghua Long. Antibodies in Infants Born to Mothers With COVID-19 Pneumonia. JAMA. Published online March 26, 2020. doi:10.1001/jama.2020.4861

Study 12. Case report from China

Case report in JAMA of baby, born at Renmin Hospital, Wuhan, by Caesarean, 23 days after mother developed Covid-19, had IgM antibodies detected in cord blood (click here). This is additional to the two Remnin cases below, because the clinical details differ substantially. Citation: Lan Dong, Jinhua Tian, Songming He, Chuchao Zhu, Jian Wang, Chen Liu, Jing Yang. Possible Vertical Transmission of SARS-CoV-2 From an Infected Mother to Her Newborn. JAMA. Published online March 26, 2020. doi:10.1001/jama.2020.4621

Study 11. Caesarean birth & neonatal infection, China

Case report (click here) of a baby born by Caesarean to an infected mother at Wuhan Tongji Hospital.  The baby was separated from the mother at birth but became infected (pharyngeal PCR at 36 hours). Both mother and baby recovered. I believe this case report is additional to the 33 Wuhan neonatal cases reported in JAMA, because the details (e.g. birth weight) do not align. This is therefore the fourth infected baby born by Caesarean.

Clinical Infectious Diseases, ciaa225, https://doi.org/10.1093/cid/ciaa225

Study 10. Two cases from Renmin Hospital, Wuhan, China

Two pregnant doctors with Covid-19 both delivered by Caesarean at term (click here). Also remnin two cases.  Babies separated and not infected. Probably additional to the 33 JAMA Wuhan neonates because neither neonate was transferred to Wuhan Children’s Hospital. Citation: Cuifang Fan, Di Lei, Congcong Fang, Chunyan Li, Ming Wang, Yuling Liu, Yan Bao, Yanmei Sun, Jinfa Huang, Yuping Guo, Ying Yu, Suqing Wang Perinatal Transmission of COVID-19 Associated SARS-CoV-2: Should We Worry?  Clinical Infectious Diseases, ciaa226, https://doi.org/10.1093/cid/ciaa226

28 March 2020 update. Three more more primary scientific reports.

Study 9. A Caesarean birth from China

This case report is in Chinese but has an English abstract. Click here. It’s from the First Affiliated Hospital, College of Medicine, Zhejiang University School of Medicine, Hangzhou. There appears to be no overlap of the authors with the Zhejiang Caesarean below, so this may be a new case. The Caesarean is reported as being “successful” which presumably means both mother and baby survived. Citation: Kang X, Zhang R, He H, Yao Y, Zheng Y, Wen X, Zhu S. Anesthesia management in cesarean section for a patient with coronavirus disease 2019. Zhejiang Da Xue Xue Bao Yi Xue Ban. 2020 May 25;49(1):0. Chinese. PMID: 32207592   

12 June reconsideration. The hospitals in S9 & S4 are both First Affiliated Hospital Zhejiang University grid.452661.2.  The full Chinese text of S9 seems to be no longer available so not possible to compare clinical details. Assume this is same case as that in S4.

Study 8. The 33 neonatal cases from China

A series of 33 neonates born to mothers who had Covid-19. All from Wuhan Children’s Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan. Reported in JAMA here. It seems possible that some or all of these infants are also included in the other Union Hospital Tongji series below.  Of the 26 neonates delivered by Caesarean three became infected. One born at 30 weeks and 2 days developed RDS, pneumonia and suspected sepsis, and required non-invasive ventilation. The authors speculate that some of his problems were related to prematurity rather than COVID-19. The other two neonates were healthy. All three survived. By inference, although this is not specifically stated in the paper, none of the seven infant born vaginally became infected.  Citation: Lingkong Zeng, Shiwen Xia, Wenhao Yuan, Kai Yan, Feifan Xiao, Jianbo Shao, Wenhao Zhou, Neonatal Early-Onset Infection With SARS-CoV-2 in 33 Neonates Born to Mothers With COVID-19 in Wuhan, China. JAMA Pediatr. Published online March 26, 2020. doi:10.1001/jamapediatrics.2020.0878

Study 7. The Quingdao case, China

This appears to be the first pregnancy case from  that city. Click here. The mother developed Covid-19 at 30 weeks but recovered and was discharged. At the time the report was written the pregnancy was ongoing. Citation: Rong Wen, Yue Sun, Quan-Sheng Xing A patient with SARS-CoV-2 infection during pregnancy in Qingdao, China Journal of Microbiology, Immunology and Infection Available online 10 March 2020 https://doi.org/10.1016/j.jmii.2020.03.004

22 March 2020 estimate. Assuming all the Union Hospital Tongji cases overlap, i.e. that Tongji has reported only 15 in total, there have been 38 published cases (39 babies) of Covid-19 infection in pregnancy. There have been no reports in the scientific literature of any maternal deaths, and all neonates have survived and not been infected. Four neonates remain undelivered.

Note 22 March 2020.  David A Schwarz (click here) in a review in Arch Pathol (preprint available March 21st) also makes the total 38 published cases.  However he includes a series published only in Chinese (his reference 17) Zhang I, Jiang Y, Wei M, Cheng BH, Zhou XC, Li J, et al. 湖北地区新型冠状病毒肺炎流行期间孕妇的 384 妊娠结局分析 [Analysis of the Pregnancy Outcomes in Pregnant Women With COVID-19 in Hubei Province]. Zhonghua Fu Chan Ke Za Zhi . 2020;55(0), E009. Available from: http://rs.yiigle.com/yufabiao/1184338.htm (accessed and translated 12 March 2020).  He reports this as including 16 cases.  For the moment I’ve not included this Hubei series, (but see Study 6a added 1 April).

Study 6a. 16 cases from Remnin, China

The cases included by David Schwarz on March 21 (see note above). English abstract (click here). Full text in Chinese here. Google translate used. The authors come from Remnin Hospital, but the paper reports that all 16 women were delivered by Caesarean at the Eastern Hospital of Wuhan University People’s Hospital.  Therefore assume no duplicates.

Study 6. The 15 Union hospital Tongji cases, China

A series of 15 pregnant women, of whom 11 had delivered and four remained undelivered from Union Hospital, Tongji Medical College, click here.

Study 3. The Sun Yat Sen series from China (withdrawn)

These 13 cases were reported from the First Affiliated Hospital of Sun Yat-sen University, Guangzhou 510080, Province. Guangdong. (click here). Also pre-publication text 10.1016@j.jinf.2020.02.028). They included 3 patients from Zhejiang, 3 from other cities of Hubei and 1 each from Fujian, Shanxi, Beijing, Guangdong, Jiangxi, Heilongjiang and Anhui.   No infected neonates but one mother seriously ill on ECMO.  16 April update. Since patients in this series came from multiple centres, both in and outside Hubei province, they are likely to overlap with other studies. 12 mothers (3 undelivered) and 9 babies have therefore been removed from the running total. However case 6, where the woman was reported to be on ECMO and the baby stillborn, does not appear to have been reported elsewhere, so remains in the running totals.

The risk of dying from Covid-19 in pregnancy

May 3, 2020

Update 2 November. This post was written when there were few reliable estimates. This is no longer the case. For the WHO best estimate click here.

For the facts click here.  This is my interpretation.

It’s not zero, 13/73 (18%) of pregnant women with Covid-19, whose cases made it into the newspapers, died (click here). But this must be an overestimate. Covid may not have caused all the deaths, and there will be selective reporting.

In the scientific papers 16/367 (4%) of women died (click here). These data should be more reliable, in that we can can be confident, at least for the women reported in detail from Iran (S67 & S70), that Covid-19 caused the deaths. The other 7 cases from Brazil and Mexico (S66) include less detail, and some were identified only from newspaper reports, so the cause of death must be in some doubt. There is also a more serious problem. All the deaths were reported in studies of maternal death due to Covid-19. Mothers who survived in the relevant regions were not reported. This must also be an overestimate.

Restricting analysis to the the larger series probably gives a better estimate. In Wuhan 0/109, Netherlands 0/91, Lombardy 0/42, NY Presbyterian/Columbia 0/33 mothers died. In total that’s zero deaths out of 275 pregnant women with Covid-19.

But the death rate can’t be zero. Some women really did die, and many mothers in the larger series were seriously ill and nearly died. In the Whuhan series (S55 here) 9/109 pregnant women had severe disease (hypoxaemia) although only one required ventilation. In the Netherlands 5/91 (S41, here), Lombardy 7/42 (S32 here), & NY Presbyterian/Columbia 2/33 (S41 here), needed intensive care. That’s 14/166 (8%) in total. There have been other reports of pregnant women who were seriously ill (S69, S50, S28, S19, S3 here).

Mortality for non-pregnant people, age 16-49, with Covid-19, who needed intensive care is 24% (ICNARC).  If pregnant women on intensive care had the same mortality, this would correspond to a 2% overall mortality. Not zero. But significantly lower than the biased newspaper rate of 18% or the biased “all scientific reports” rate of 4%.

A two percent maternal mortality rate from Covid-19 is my best guess.

Let’s put this in context. 98% of women who develop Covid-19 in pregnancy will survive. But the background risk of mothers dying in pregnancy these days is only 0.01%. This means the risk of a mother dying, if she gets Covid-19, may be 200 times greater than the background risk in pregnancy.

Covid-19 is a serious disease. Don’t underestimate it.
