Determinants of Conception and Adverse Pregnancy Outcomes in Women with Endometriosis: A Longitudinal Study

Endometriosis, affecting approximately 10% of reproductive-aged women globally, poses significant challenges, including chronic pelvic pain, dysmenorrhea, and infertility. In low- and middle-income countries like India, accessibility to affordable infertility care remains a concern. This multicenter prospective cohort study, conducted across six tertiary care hospitals in India from 2017 to 2022, aims to explore the natural progression of conception and pregnancy outcomes in women with endometriosis. Of the 257 participants, 19.1% conceived during the study, revealing significant geographic and income-based variations (p < 0.001, p = 0.01). Dysmenorrhea (p < 0.001) and dyspareunia (p=0.027) were correlated with conception, while no such associations were found with chronic pelvic pain or menstrual factors. Lesion type, number, and severity showed no conclusive link with conception. Natural conception occurred in 70% of cases, with an average post-surgery conception time of 282.1 days. Live birth rate was 85.7%, while complications included placenta previa (16.4%), preeclampsia (4.1%), and preterm births (4.1%). This study, one of the first in India on endometriosis-related fertility progression, emphasizes the need for comprehensive understanding and management of conception and pregnancy outcomes. Considering India's substantial endometriosis burden, the study recommends prioritizing larger multicenter investigations for a better understanding and effective strategies for infertility management.

Prioritizing the Health and Well-Being of the Indigenous Communities in India

The International Day of the World's Indigenous Peoples and the Tribal Pride Day hold significant importance in India, home to 106 million indigenous individuals. There are 705 recognized Scheduled Tribes (STs) in India that enrich the nation's cultural fabric but experience disproportionately high morbidity and mortality. Historical injustice, geographic isolation, and cultural diversity deeply influence ST health causing disparities between indigenous and non-indigenous health indicators. To meet Sustainable Development Goals, India established the Ministry of Tribal Affairs and implemented various health initiatives. However, climate change, deforestation, limited education and employment opportunities, poverty, and under-representation pose a challenge. Empowerment, inclusive policies, community-specific targets, resource allocation, technology utilization, and multi-sectoral collaboration are vital for indigenous health. Achieving health equity for indigenous communities is a global commitment and moral imperative. By addressing historical wrongs, and working holistically, we must ensure that indigenous communities in India and beyond enjoy improved health and well-being.

Increased risk of early-onset preeclampsia in pregnant women with COVID-19

OBJECTIVE

To estimate incidence, risk of early and late-onset preeclampsia (PE) and understand their relationship with severity of COVID-19.

METHODS

Pregnant women with COVID-19 (n = 1929) were enrolled from 1 April 2020 to 24 February 2022. Primary outcome measure was incidence and risk of early onset PE in women with COVID-19.

RESULTS

The incidence of early and late-onset PE was 11.4% and 5.6%. Moderate to severe COVID-19 was associated with eight times higher risk of early onset PE [aOR = 8.13 (1.56-42.46), p = 0.0129] compared to asymptomatic group.

CONCLUSIONS

Risk of early onset PE was higher in pregnant women with symptomatic COVID-19 as compared to asymptomatic women.

Empowering Health care Systems and Communities for Snakebite Envenoming Control in India

Snakebite envenoming (SBE) is a global health challenge, predominantly affecting economically disadvantaged regions. India contributes significantly to global snakebite mortality. Since 2013, the Indian Council of Medical Research (ICMR) has spearheaded efforts to combat SBE. A multi-sectoral engagement in the snakebite research projects and inputs from communities, traditional healers, and the health system have led to the creation of an Information Education and Communication (IEC) material suite, including management flowchart, information booklets, posters, and brochures, all available in local languages. These resources were broadly disseminated in high-burden regions in Maharashtra and Odisha, resulting in an approximately 10% increase in case reporting within a year. This holistic approach, engaging diverse stakeholders and addressing multiple facets of SBE, offers promise for alleviating the snakebite burden, not only in India but also in other low- and middle-income countries across South Asia, Africa, and South America, holding potential for broader positive global impact.

Different impact of COVID-19 on symptomatic pregnant and postpartum women in low-income countries and low- and middle-income countries

The adverse outcomes of COVID‐19 among pregnant women have been pronounced in the low‐income countries compared with low‐ and middle‐income countries.

Dysregulated serum and seminal plasma levels of surfactant protein D and MCP-1 in men with genital tract infection/inflammation

PROBLEM

Surfactant protein D (SP-D), a multimeric collectin expressed by testicular mucosal epithelia and is positively regulated by testosterone. It exerts antimicrobial effects, modulates inflammation and rescued spermatogenesis in a murine model. Various cytokines and chemokines, including MCP-1, play a key role in regulating the inflammation in rat and human testis. The study aimed to investigate the role of SP-D and involvement of chemokines and cytokines in the male infertility associated with urogenital infections or inflammation.

METHOD OF STUDY

The cross-sectional study evaluated levels of SP-D, testosterone, estradiol and the cytokines/chemokines including MCP-1 in the serum and semen samples of fertile and infertile Indian men with and without urogenital infections/inflammation (n = 76).

RESULTS

Both fertile and infertile males with urogenital infection/inflammation had significantly lower levels of SP-D and higher levels of the chemokine, Monocyte chemoattractant protein 1 (MCP-1) in the serum and seminal plasma. Seminal plasma of these males exhibited significantly higher proportion of proteolytically degraded forms of SP-D. The serum SP-D levels positively correlated with testosterone/estradiol (TE) ratio. There was no significant correlation between the SP-D levels in seminal plasma and sperm count/motility. With a significant area under the Receiver Operating Characteristic curves, the serum and seminal plasma SP-D levels exhibited significant potential to predict infertility with high sensitivity and specificity in men with genital infections/inflammation.

CONCLUSIONS

The circulating and seminal plasma SP-D levels were decreased in men with urogenital infection and inflammation. This could be due to their engagement at the site of infection, dysregulated expression owing to the altered hormonal profile and increased proteolytic degradation.

Endometriosis and inflammatory immune responses: Indian experience

Endometriosis is a public health disorder affecting ∼ 247 million women globally and ∼ 42 million women in India. Women with endometriosis suffer from dysmenorrhea, chronic pelvic pain, dyspareunia, dyschezia, fatigue, depression, and infertility leading to significant socioeconomic impact and morbidity. The etiology of endometriosis is not understood well even after 100 years of research. Currently, there is no permanent cure for endometriosis. The inflammatory immune response is one of the important features of etiopathogenesis of endometriosis and therefore understanding the inflammatory immune response would lead to a better understanding of this enigmatic disorder and may also lead to biomarker discovery for diagnosis of endometriosis. We investigated the autoimmune etiology of endometriosis in the Indian population. Using the proteomics approach, anti-endometrial antibodies (AEAs) were detected in Indian women with endometriosis [anti-endometrial antibodies - tropomyosin 3 (TPM3), stomatin-like protein2 (SLP-2), and tropomodulin 3 (TMOD3)]. The studies on AEAs provided a better understanding of autoimmune mechanisms in endometriosis. All three subtypes of endometriosis; superficial peritoneal, ovarian endometrioma, and deep infiltrating endometriosis were reported in Indian women. In this review, we discuss our experiences of the inflammatory immune response, autoimmunity, comorbidities, and clinical phenotypes in women with endometriosis in India.

Clinical presentation, pregnancy complications, and outcomes of pregnant women with COVID-19 during the Omicron-dominant third wave in Mumbai, India

OBJECTIVE

To study clinical presentation, disease severity, pregnancy complications, and maternal outcomes in women affected with coronavirus disease 2019 (COVID-19) during the third wave compared with the first and second waves of COVID-19.

METHODS

A retrospective, observational cohort study was conducted among 2058 pregnant and postpartum women with COVID-19 admitted during three wave periods at a tertiary care COVID-19-dedicated hospital.

RESULTS

The number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) -infected pregnant and postpartum women with symptoms of COVID-19 was four times higher during the third wave compared with the first (odds ratio [OR] 4.6, 95% confidence interval [CI] 3.5-6.0, P < 0.001). There was a significantly lower proportion of pregnant and postpartum women with moderate to severe COVID-19 during the third wave (0.6%, 2/318) compared with those during the first wave (2.4%, 27/1143, P < 0.001) and second wave (14.4%, 86/597, P < 0.001). The intensive care/high dependency unit admissions during the third wave were significantly lower (2.5%, 8/318) than during the second wave (14.7%, 88/597; OR 0.2, 95% CI 0.1-0.3, P < 0.001) but similar to the first wave (2.4%, 27/1143).

CONCLUSIONS

Decreased severity of COVID-19, reduced maternal mortality, and morbidity were reported in the third wave compared with the first wave and second wave of COVID-19 in the Mumbai Metropolitan Region, India.

TRIAL REGISTRATION

Clinical characteristics and surgical management of endometriosis-associated infertility: A multicenter prospective cohort study

OBJECTIVE

To study clinical, surgical characteristics and the relationship between endometriosis lesion types and conception rate after surgery in infertile women with endometriosis.

METHODS

A prospective, multicenter cohort of 204 women (age 20-35 years) with endometriosis was followed up post-surgery between November 2017 and February 2020 at three tertiary-care hospitals.

RESULTS

Based on the severity of endometriosis lesion type, deep infiltrating endometriosis (DIE) (81/204, 39.7%) was the most common lesion; followed by ovarian endometriosis (OMA) (64/204, 31.4%), and superficial peritoneal endometriosis (SUP) (59/204, 28.9%). Endometriosis patients had a single lesion type (94/204, 46.1%), two lesion types (77/204, 37.7%), or three lesion types (33/204, 16.2%) with significant differences between regions (P < 0.001). Around 40% (37/95) of obese women had SUP (P = 0.003) whereas 78% (14/18) of underweight women had DIE (P < 0.001). Significant differences in mean Endometriosis Fertility Index scores between endometriosis lesion types and patients with one, two, and three types of lesions were observed (P < 0.001). The majority (22/32, 68.8%) of the women conceived naturally after the surgery. Half (16/32; 50%) of the women with a single lesion type conceived after the surgery; of which most (13/16, 81.2%) had SUP, followed by OMA (2/16, 12.5%), and DIE (1/16, 6.3%).

CONCLUSION

Women with SUP and only one type of endometriotic lesion were more likely to conceive post-surgery.

Increased spontaneous preterm births during the second wave of the coronavirus disease 2019 pandemic in India

OBJECTIVE

To compare spontaneous preterm birth (SPTB) and iatrogenic preterm birth (IPTB) rates during both waves of the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

Retrospective analysis of the PregCovid registry of pregnant women with COVID-19 was performed at a dedicated COVID-19 hospital in Mumbai, India. The data of 1630 women were analyzed for this study between April 4, 2020 and July 4, 2021. Prepandemic data were analyzed and compared with pandemic data. Main outcome measure was spontaneous preterm birth rate.

RESULTS

Preterm deliveries were higher during the second wave (46/329; 14%) compared with the first wave (82/807; 10.2%) of the COVID-19 pandemic (P = 0.065). Higher SPTBs were reported during the second wave than the first wave (12.5% versus 8.3%) (P = 0.03) as well as the prepandemic period (12.5% versus 10.5%) (P = 0.286). IPTBs were significantly lower in the pandemic period than in the prepandemic period (1.8 versus 3.3) (P = 0.012).

CONCLUSION

In Mumbai, India, we found an unusual change in SPTBs during the 6 months of the second wave of COVID-19 compared with the previous 10 months of the first wave of pandemic and 1 year of prepandemic.

Protocol for a prospective, hospital-based registry of pregnant women with SARS-CoV-2 infection in India: PregCovid Registry study

INTRODUCTION

Pregnant women are at increased risk of contracting COVID-19 due to several factors and therefore require special attention. However, the consequences of the COVID-19 pandemic on pregnant women and their newborns remain uncharted. The PregCovid registry aims to document the impact of SARS-CoV-2 infection on pregnant, postpartum women and their newborns. The aim of the registry is also to determine mother-to-child transmission of SARS-CoV-2 infection in India.

METHODS AND ANALYSIS

PregCovid is a hospital-based registry for capturing information of pregnant, postpartum women with COVID-19 and their newborns in India. Medical case records of pregnant and postpartum women with a laboratory-confirmed diagnosis of COVID-19 will be captured in real-time using an online electronic patient record software. The data analysis will be carried out for symptoms, the severity of COVID-19, pregnancy complications, maternal morbidity and mortality, neonatal complications, mother-to-child transmission, etc. Data analysis will be carried out for different waves of the COVID-19 pandemic for rapid response and developing strategies well in advance to manage pregnant women infected with SARS-CoV-2. The evidence generated from the registry will be regularly shared with the appropriate authorities for policy decisions. Thus, the registry data may be useful for planning the strategies for better management of pregnant women with COVID-19.

ETHICS AND DISSEMINATION

The study has been approved by the Institutional Ethics Committees of all the participating study sites under the Medical Education and Drugs Department, Government of Maharashtra, Topiwala National Medical College & BYL Nair Charitable Hospital, Mumbai and ICMR-National Institute for Research in Reproductive and Child Health, Mumbai, India. The results from this study will be disseminated with local, state, and national health authorities, collaborators and the general population on the study website (https://pregcovid.com) as well as dissemination through scientific meetings and publications.

Outcomes in neonates born to mothers with COVID-19 during the second wave in India

COVID-19 pandemic has affected all age groups globally including pregnant women and their neonates. The aim of the study was to understand outcomes in neonates of mothers with COVID-19 during the first and second waves of COVID-19 pandemic. A retrospective analysis of 2524 neonates born to SARS-CoV-2-infected mothers was conducted during the first wave (n = 1782) and second wave (n = 742) of the COVID-19 pandemic at five study sites of the PregCovid registry in Maharashtra, India. A significant difference was noted in preterm birth, which was higher in the second wave (15.0%, 111/742) compared to the first wave (7.8%, 139/1782) (P < 0.001). The proportion of neonates requiring NICU admission was significantly higher in the second wave (19.0%, 141/742) as compared to that in the first wave (14.8%, 264/1782) (P < 0.05). On comparing regional differences, significantly higher neonatal complications were reported from Mumbai metropolitan region (P < 0.05). During the second wave of COVID-19, birth asphyxia and prematurity were 3.8- and 2.1-fold higher respectively (P < 0.001). Neonatal resuscitation at birth was significantly higher in second wave (3.4%, 25/742 vs 1.8%, 32/1782) (P < 0.05). The prevalence of SARS-CoV-2 infection in neonates was comparable (4.2% vs 4.6%) with no significant difference between the two waves.

CONCLUSION

Higher incidence of adverse outcomes in neonates born to SARS-CoV-2-infected mothers in the second wave of COVID-19 as compared to the first wave.

TRIAL REGISTRATION

PregCovid study is registered with the Clinical Trial Registry of India (CTRI/2020/05/025423, Registered on 28/05/2020).

WHAT IS KNOWN

• The second wave of COVID-19 was more lethal to pregnant women than the first wave. Newborns are at risk of developing complications.

WHAT IS NEW

• Birth asphyxia, prematurity, and neonatal resuscitation at birth were significantly higher in the second wave as compared to those in the first wave of the COVID-19 pandemic in India.

Genetics of Male Infertility - Present and Future: A Narrative Review

Infertility affects 8%–12% of couples worldwide with a male factor contributing to nearly 50% of couples either as a primary or contributing cause. Several genetic factors that include single-gene and multiple-gene defects associated with male infertility were reported in the past two decades. However, the etiology remains ambiguous in a majority of infertile men (~40%). The objective of this narrative review is to provide an update on the genetic factors associated with idiopathic male infertility and male reproductive system abnormalities identified in the last two decades. We performed a thorough literature search in online databases from January 2000 to July 2021. We observed a total of 13 genes associated with nonobstructive azoospermia due to maturation/meiotic arrest. Several studies that reported novel genes associated with multiple morphological abnormalities of the sperm flagella are also discussed in this review. ADGRG2, PANK2, SCNN1B, and CA12 genes are observed in non-CFTR-related vas aplasia. The genomic analysis should be quickly implemented in clinical practice as the detection of gene abnormalities in different male infertility phenotypes will facilitate genetic counseling.

Pregnancy Outcomes and Maternal Complications During the Second Wave of Coronavirus Disease 2019 (COVID-19) in India

Rates of severe coronavirus disease 2019 (COVID-19), intensive care unit admission, and maternal mortality increased among pregnant and postpartum women admitted for COVID-19 in the second wave compared with the first wave in India.

Differential impact of COVID-19 in pregnant women from high-income countries and low- to middle-income countries: A systematic review and meta-analysis

BACKGROUND

SARS-CoV-2 has infected a large number of pregnant women.

OBJECTIVE

To compare clinical, perinatal outcomes of women with COVID-19 from high-income countries (HICs) and low- to middle-income countries (LMICs).

SEARCH STRATEGY

Online databases were searched.

SELECTION CRITERIA

Original studies on pregnant women with COVID-19 were included.

DATA COLLECTION AND ANALYSIS

Information on clinical presentation, co-morbidities, pregnancy outcomes, neonatal outcomes, and SARS-CoV-2 infection in neonates was extracted.

MAIN RESULTS

The pooled estimate of SARS-CoV-2 positive neonates is 3.7%. Symptomatic presentations are less common in LMICs compared to HICs (odds ratio [OR] 0.38). Diabetes (OR 0.5), hypertension (OR 0.5), and asthma (OR 0.14) are commonly reported from HICs; hypothyroidism (OR 2.2), anemia (OR 3.2), and co-infections (OR 6.0) are commonly reported in LMICs. The overall risk of adverse pregnancy outcomes is higher in LMICs compared to HICs (OR 2.4). Abortion (OR 6.2), stillbirths (OR 2.0), and maternal death (OR 7.8) are more common in LMICs. Preterm births and premature rupture of membranes are comparable in both groups. Neonatal deaths (OR 3.7), pneumonia (OR 7.5), and neonatal SARS-CoV-2 infection (OR 1.8) are commonly reported in LMICs.

CONCLUSIONS

In LMICs, pregnant women and neonates are more vulnerable to adverse outcomes due to COVID-19. PROSPERO registration no: CRD42020198743.

Protocol for a case-control study investigating the clinical phenotypes and genetic regulation of endometriosis in Indian women: the ECGRI study

INTRODUCTION

Endometriosis is one of the common, gynaecological disorders associated with chronic pelvic pain and subfertility affecting ~10% of reproductive age women. The clinical presentation, etiopathogenesis of endometriosis subtypes and associated risk factors are largely unknown. Genome-Wide Association (GWA) Studies (GWAS) provide strong evidence for the role of genetic risk factors contributing to endometriosis. However, no studies have investigated the association of the GWAS-identified single-nucleotide polymorphism (SNPs) with endometriosis risk in the Indian population; therefore, one-sixth of the world's population is not represented in the global genome consortiums on endometriosis. The Endometriosis Clinical and Genetic Research in India (ECGRI) study aims to broaden our understanding of the clinical phenotypes and genetic risks associated with endometriosis.

METHODS AND ANALYSIS

ECGRI is a large-scale, multisite, case-control study of 2000 endometriosis cases and 2000 hospital controls to be recruited over 4 years at 15 collaborating study sites across India covering representative Indian population from east,north-east, north, central, west and southern geographical zones of India. We will use the World Endometriosis Research Foundation Endometriosis Phenome and Biobanking Harmonisation Project (WERF-EPHect) data collection instruments for capturing information on clinical, epidemiological, lifestyle, environmental and surgical factors. WERF-EPHect standard operating procedures will be followed for the collection, processing and storage of biological samples. The principal analyses will be for main outcome measures of the incidence of endometriosis, disease subtypes and disease severity determined from the clinical data. This will be followed by GWAS within and across ethnic groups.

ETHICS AND DISSEMINATION

The study is approved by the Institutional Ethics Committee of Indian Council of Medical Research-National Institute for Research in Reproductive Health and all participating study sites. The study is also approved by the Health Ministry Screening Committee of the Government of India. The results from this study will be actively disseminated through discussions with endometriosis patient groups, conference presentations and published manuscripts.

Clinical Characteristics, Management, and Short-Term Outcome of Neonates Born to Mothers with COVID-19 in a Tertiary Care Hospital in India

INTRODUCTION

We describe the clinical characteristics, management, and short-term outcomes of SARS-CoV-2 neonates born to mothers with COVID-19 in a tertiary care hospital in Mumbai, India.

METHODS

The study is a retrospective analysis of 524 neonates born to mothers with COVID-19 admitted from 14th April 2020 to 31st July 2020.

RESULTS

SARS-CoV-2 infection was detected in 6.3% of the newborns of the mothers with COVID-19. No significant differences were observed between maturity at gestation, birth weight and sex of SARS-CoV-2 infected and noninfected newborns. The risk of sepsis was 4.09 [95% confidence interval (95% CI) 1.28-13.00] fold higher in the neonates with SARS-CoV-2 as compared to the noninfected group (p = 0.031). Poor feeding was significantly more common among SARS-CoV-2 infected neonates (12.1%) as compared to the noninfected neonates (2.7%) (p = 0.017). There was a total of 13 neonatal deaths, of which 3 deaths occurred in SARS-CoV-2 infected neonates (9%) while 10 (2.04%) in the SAR-CoV-2 negative group. The risk of neonatal death was higher in SARS-CoV-2 infected newborns [odds ratio (OR) 4.8; 95% CI 1.25-18.36].

CONCLUSION

Neonatal SARS-CoV-2 infection is observed in almost 6% of neonates born to mothers with perinatal COVID-19. There is a higher risk of adverse outcomes such as neonatal sepsis and death in the SARS-CoV-2 infected as compared to the noninfected neonates.

Clinical characteristics, outcomes, & mortality in pregnant women with COVID-19 in Maharashtra, India: Results from PregCovid registry

Background & objectives

The PregCovid registry was established to document the clinical presentations, pregnancy outcomes and mortality of pregnant and post-partum women with COVID-19.

Methods

The PregCovid registry prospectively collects information in near-real time on pregnant and post-partum women with a laboratory-confirmed diagnosis of SARS-CoV-2 from 19 medical colleges across the State of Maharashtra, India. Data of 4203 pregnant women collected during the first wave of the COVID-19 pandemic (March 2020-January 2021) was analyzed.

Results

There were 3213 live births, 77 miscarriages and 834 undelivered pregnancies. The proportion of pregnancy/foetal loss including stillbirths was six per cent. Five hundred and thirty-four women (13%) were symptomatic, of which 382 (72%) had mild, 112 (21%) had moderate, and 40 (7.5%) had severe disease. The most common complication was preterm delivery (528, 16.3%) and hypertensive disorders in pregnancy (328, 10.1%). A total of 158 (3.8%) pregnant and post-partum women required intensive care, of which 152 (96%) were due to COVID-19 related complications. The overall case fatality rate (CFR) in pregnant and post-partum women with COVID-19 was 0.8 per cent (34/4203). Higher CFR was observed in Pune (9/853, 1.1%), Marathwada (4/351, 1.1%) regions as compared to Vidarbha (9/1155, 0.8%), Mumbai Metropolitan (11/1684, 0.7%), and Khandesh (1/160, 0.6%) regions. Comorbidities of anaemia, tuberculosis and diabetes mellitus were associated with maternal deaths.

Interpretation & conclusions

The study demonstrates the adverse outcomes including severe COVID-19 disease, pregnancy loss and maternal death in women with COVID-19 in Maharashtra, India.

Clinical presentations, pregnancy complications, and maternal outcomes in pregnant women with COVID-19 and tuberculosis: A retrospective cohort study

Pregnant women with symptomatic COVID‐19 should also be tested for TB in countries with a high burden of TB. The infrastructure of the TB Program can be utilized for the control of COVID‐19, and vice versa.

Co-infection of malaria and early clearance of SARS-CoV-2 in healthcare workers

Healthcare workers (HCWs) are at higher risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Information regarding co-infection of SARS-CoV-2 with vector-borne diseases (malaria and dengue) is crucial especially for the countries wherein malaria and dengue are endemic. The objective was to study the prevalence, demographic, clinical presentations among HCWs with coronavirus disease 2019 (COVID-19) and to compare the viral clearance in HCWs with COVID-19 and co-infection of malaria and dengue. This retrospective study was conducted at a dedicated COVID-19 hospital, BYL Nair Charitable Hospital (NH), Mumbai, India April 6th-October 31st 2020. The SARS-CoV-2 infection in HCWs was confirmed by reverse transcription-plymerase chain reaction. Out of 491 HCWs infected with SARS-CoV-2, analysis of viral clearance was carried out in 467 HCWs over seven month periods, The prevalence of SARS-CoV-2 infection in HCWs was 13% (491 out of 3711). Out of the HCWs with COVID-19, prevalence of SARS-CoV-2 infection was higher among security guards (25%) with 1% mortality. The co-infection of malaria or dengue was reported in 31 HCWs (6.3%). The mean duration of virus clearance was longer (12 days) in symptomatic HCWs as compared to asymptomatic (8 days, p < .005). The recovery of SARS-CoV-2 infection in HCWs was faster (mean 8 days) with co-infection of malaria than without malaria (p < .005). We recommend universal testing of HCWs, to optimize staffing levels during the current pandemic as HCWs are the most precious resource. There is a need to effectively implement standard protocols for prevention of vector-borne diseases, especially in the hospital settings.

Delirium in a pregnant woman with SARS-CoV-2 infection in India

• There is limited information on impact of COVID-19 on mental health of pregnant women. • Management of delirium in a 30-weeks pregnant woman with COVID-19 was challenging. • Training of obstetricians for managing the psychiatric emergencies is required especially in low resource settings.

Clinical Presentation of Cases with SARS-CoV-2 Reinfection/ Reactivation

BACKGROUND

Reinfection/reactivation of SARS-CoV-2 has been a matter of great interest from the immunological and vaccine perspective. However, little is known about the clinical presentation of such reinfection/reactivation. We report a case series of 9 COVID-19 patients having experienced two clinically- and/or virologically-confirmed episodes of COVID-19.

METHODS

Epidemiological and clinical characteristics of 9 healthcare workers (HCWs) with two episodes of SARS-CoV-2 are described.

RESULTS

The incidence of reinfection/reactivation amongst the HCWs was 2% (9 out of 491) with an average remission period of 66 days (range 43-78 days). Amongst the cases of reinfection 4/9 were asymptomatic in first episode were symptomatic in second episode. There is negative correlation between numbers of days the patients took to become SARS-CoV-2 negative by RT-CPR and/or clinically recover in the first episode and the second episode irrespective for the time spent in remission.

CONCLUSION

Shorter durations of SARS-COV-2 infection in the first episode are associated with longer time to recovery in the second episode in patients with re-infection/reactivation.

Impact of SARS-CoV-2 on multiple gestation pregnancy

Objective

To assess clinical presentations, pregnancy complications, and maternal and neonatal outcomes among women with multiple gestation pregnancy (MGP) and confirmed SARS‐CoV‐2 (COVID‐19) infection and to compare the data with a pre‐pandemic period.

Methods

A retrospective study at a dedicated COVID‐19 Hospital in Mumbai, India. Data were obtained from the PregCovid Registry of pregnant and postpartum women with PCR‐confirmed SARS‐CoV‐2 infection from April to September, 2020. Data were also compared with a cohort of women with MGP attending the hospital pre‐pandemic (n = 63).

Results

Data from 879 women (singleton pregnancy, n = 859; MGP, n = 20) with COVID‐19 were assessed. The twinning rate was 34.2 per 1000 births. As compared with singleton pregnancies, a higher proportion of women with MGP and Covid‐19 delivered preterm (P = 0.001). Spontaneous abortions were also higher in the MGP group than in the singleton group (P = 0.055). The incidence of pre‐eclampsia/eclampsia was higher in the COVID‐19 MGP group than in both the COVID‐19 singleton (41.6% vs. 7.9%) and pre‐pandemic MGP (50.0% vs. 12.7%) groups.

Conclusion

There was a higher risk of pre‐eclampsia among women with MGP and COVID‐19. Women with MGP and COVID‐19 infection should receive special attention with a multidisciplinary approach to both maternal and neonatal care during the pandemic.

SARS‐CoV‐2 infection was found to be associated with increased risk of pre‐eclampsia and premature rapture of membranes among pregnant women with multiple gestation.

Co-infection of malaria and dengue in pregnant women with SARS-CoV-2

Physicians and obstetricians should be vigilant so that they can swiftly identify co‐infections of malaria and dengue in pregnant women with COVID‐19.

Differential proteomics leads to identification of domain-specific epididymal sperm proteins

The alteration in the protein signatures of the testicular sperm during its epididymal sojourn makes it functionally competent for successful fertilization. The present study was undertaken to identify the proteins acquired on its 2 domains, that is, the head and the flagellum, during the epididymal transit using a differential proteomics approach. Testicular sperm proteome was compared with cauda epididymal sperm proteome in rat. The protein spots exclusively present in the cauda epididymal sperm proteome were searched in the cauda sperm head proteome and the cauda sperm flagella proteome, and a total of 335 spots were found by alignment and auto-matching of the gels, of which 140 could be identified by mass spectrometry. Database search revealed that of these 9 proteins were novels. Gene Ontology annotation revealed that the identified proteins were distributed across different cellular components and were primarily involved in metabolic processes. The study also provides information on the localization of these proteins on the sperm domains, which indirectly gives a clue about its putative function. Validation of 3 proteins, namely MMSDH, NDUFS1, and UQCRC2, using antibodies very elegantly demonstrates that the strategy has been very effective. This comprehensive data of domain-specific epididymal sperm proteins will be useful in development of newer targets for posttesticular contraception and diagnostic markers for infertility.
