COVID-19 related maternal mortality cases in associated with Delta and Omicron waves and the role of lung ultrasound.

Objective: To present coronavirus disease-2019 (COVID-19) related maternal mortality in relation to Delta and Omicron waves and to investigate the role of lung ultrasound (LUS) in estimating mortality. Materials and Methods: This retrospective cohort study was conducted in the obstetrics and gynecology clinic of a tertiary pandemic hospital between March 2020 and January 2022. The hospitalized pregnant women with COVID-19 diagnosis and maternal deaths were studied in relation with Delta and Omicron waves. The relationship between LUS scores of hospitalized patients and maternal mortality was explored. Results: Thousand and sixty-five pregnant women were hospitalized because of COVID-19 infection. Fifty-one (4.79%) of these patients had critical sickness, 96 (9.01%) of them had severe illness, 62 (5.82%) of them were admitted to the intensive care unit and 28 (2.63%) of all hospitalized pregnant women had died. Of the 1.065 patients, 783 (73.5%) were hospitalized before the Delta wave and the maternal mortality rate was 1.28% (10/783), 243 (22.8%) were hospitalized during the Delta wave and the maternal mortality rate was 7% (17/243) [relative risk (RR)=5.478, 95% confidence interval (CI) (2.54-11.8), z=4.342, p<0.001]. During the Omicron wave 39 (3.66%) patients were hospitalized and the maternal mortality rate was 2.56% (1/39). Maternal mortality rates, according to LUS scores, were 0.37% (1/273) for LUS 0, 0.72% (2/277) for LUS 1, 2.58% (10/387) for LUS 2 and 11.72% (15/128) for LUS 3 respectively (LUS 3 vs. others; maternal mortality: RR=8.447, 95% CI (4.11-17.34), z=5.814, p<0.0001). There were no vaccinated patients in the study cohort. Conclusion: The maternal mortality rate was relatively high, particularly during the Delta wave at our referral center. The Delta wave, delayed vaccination and vaccine hesitancy of pregnant women might have important roles in maternal mortality. Higher LUS scores should warn clinicians of an increased risk of maternal death.

Outcomes of universal SARS-CoV-2 testing program in pregnant women admitted to hospital and the adjuvant role of lung ultrasound in screening: a prospective cohort study.

BACKGROUND: The emerging evidence for the asymptomatic carriers of SARS-CoV-2 infection emphasized the critical need for universal screening of pregnant women. OBJECTIVES: This study aimed to present the prevalence of overall and asymptomatic SARS-CoV-2 infection rates in pregnant women admitted to the hospital, and assess the diagnostic accuracy of maternal symptoms and lung ultrasound (LUS) findings in detecting the infection. PATIENTS AND METHODS: This prospective cohort study was conducted at a single tertiary center in Istanbul, Turkey, for a month period starting from 27 April 2020. Women with a confirmed pregnancy regardless of the gestational week admitted to the obstetric unit with any indication were consecutively underwent LUS and PCR testing for SARS-CoV-2. RESULTS: A total of 296 patients were included for the final analysis. The universal screening strategy diagnosed 23 pregnant women (7.77%) with SARS-CoV-2 infection. The rate of symptomatic and asymptomatic patients diagnosed with SARS-CoV-2 was found as 3.72% (n = 11) and 4.05% (n = 12), respectively. Four of nine women who underwent a second testing for SARS-CoV-2 upon abnormal LUS findings were found positive eventually (17.4%, n = 4/23). The asymptomatic pregnant women with LUS score of 1 and those with normal LUS findings were considered as likely to be normal. Symptomatic patients with LUS score of 1 and those with score of 2 or 3 were considered as abnormal. On a secondary diagnostic performance analysis, the positive predictive value and the sensitivity were found as 44% and 47.8% for the triage based on maternal symptoms and, 82.3% and 60.9% for the triage based on LUS, respectively. CONCLUSION: A one-month trial period of universal testing for SARS-CoV-2 infection with RT-PCR in pregnant women who admitted to the hospital showed an overall and asymptomatic infection diagnose rate of 7.77% and 4%, respectively. Using lung ultrasound was found more predictive in detecting the infection than the use of symptomatology solely.

Anxiety levels and obsessive compulsion symptoms of pregnant women during the COVID-19 pandemic.

OBJECTIVE: Reliable data regarding maternal mental well-being during the Severe Acute Respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic are scarce. This study aimed to assess the state/trait anxiety and obsessive-compulsive symptoms of pregnant women and compare those with the non-pregnant population using patient-reported validated outcome measures. MATERIALS AND METHODS: This prospective case-control study was conducted at a tertiary 'Coronavirus Pandemic Hospital' in Istanbul, Turkey in April, 2020. Pregnant and non-pregnant women were consecutively allocated to two groups regardless of gestational age. The primary outcome was to identify the anxiety levels and obsessive-compulsive symptoms of pregnant women during the SARS-CoV-2 pandemic using the State-Trait Anxiety inventory (STAI) and Maudsley Obsessive-Compulsive inventory (MOCI), respectively. RESULTS: Two hundred three pregnant women and 101 non-pregnant women were included. The mean STAI-S questionnaire score of pregnant and nonpregnant women was 41.96±9.15 and 46.62±12, respectively (p=0.001). The overall incidence of STAI >40 in pregnant and non-pregnant women was 62.6% and 73.3%, respectively. The mean total score of MOCI was 17.9±6.7 and 15±6.6 in pregnant and non-pregnant women, respectively. The overall incidence of 30-item-MOCI ≥13.1 in pregnant and non-pregnant women was 61.6% (125/203) and 30.7% (31/103), respectively (p<0.001). CONCLUSION: State anxiety and obsessive-compulsive symptoms in pregnant women were found increased during the current SARS-CoV-2 pandemic. Pregnant women showed more favourable anxiety levels compared with non-pregnant women. These findings can be used to improve the coping skills of pregnant women during the pandemic, to prepare for the post-pandemic period, and to deal with the long-term mental health impact of COVID-19.
