Objectives: To evaluate serum neutrophil gelatinase-associated lipocalin (NGAL) concentrations of pregnant women complicated with coronavirus disease 2019 (COVID-19) and investigate its diagnostic value for the severity of COVID-19.
Methods: Of the 46 pregnant women with COVID-19 included in the study, we further classified these women into 2 subgroups: the non-severe COVID-19 group (n=25) and the severe COVID-19 group (n=21).
Results: Neutrophil gelatinase-associated lipocalin plasma concentrations were significantly higher in pregnant women complicated with severe COVID-19 (90 [53.1-207.7] ng/ml) compared to those from pregnant women with non-severe COVID-19 (51.8 [39.6-70.3] ng/ml) and healthy pregnant women (44.3 [32.2-54.1] ng/ml, <0.001). Also, at a cutoff value of 72 ng/ml, NGAL predicted severe COVID-19 with a sensitivity rate of 57% and a specificity rate of 84%. Serum NGAL level (adjusted hazard ratio [aHR]=1.020, 95% confidence interval [CI]= [1.006-1.035], =0.007), and D-dimer level (aHR=2.371, 95% CI= [1.085-5.181], =0.030) were the variables that were revealed to be significantly associated with the disease severity.
Conclusion: We demonstrated that NGAL was highly associated with COVID-19 severity. We consider that NGAL might be a useful biomarker to diagnose the disease severity in patients with COVID-19.

No study has examined the association between dietary insulin load (DIL) and insulin index (DII) with developing gestational diabetes mellitus (GDM) during pregnancy. This study aimed to investigate the association between DIL and DII and risk of GDM in a group of pregnant women in Iran. In this prospective cohort study, 812 pregnant in their first trimester were recruited and followed.

The quality of prenatal care for women during pregnancy, in terms of monitoring somatic development, is generally high. The study aims to evaluate the psychosocial situation (well being) of pregnant women during a physiological pregnancy. The care of psychosocial issues of pregnant women is not systematic and often does not occur at all.

Background: In low-income countries, women with disabilities face numerous challenges in accessing sexual and reproductive health services and experience high unintended pregnancy rates and adverse pregnancy outcomes, with 42% of cases ending in abortion. However, little is known about unintended pregnancy among women with disabilities in Ethiopia. Therefore, this study aimed to assess the prevalence of unintended pregnancy and associated factors among women with disabilities in the Central Regional State of Ethiopia.

Objective This study aimed to investigate whether the amount of blood loss during delivery in patients with low-lying placenta is affected by the planned mode of delivery, internal os distance, and warning bleeding. Materials and methods We conducted a single-center retrospective study encompassing women with singleton pregnancies diagnosed with low-lying placenta between January 2012 and December 2021. Data for maternal demographic details and pregnancy outcomes were extracted from the institution's records.

Alpha-1 antitrypsin deficiency (AATD) is an inherited condition characterized by reduced plasma levels of alpha-1 antitrypsin (AAT), often leading to pulmonary diseases primarily emphysema and/or chronic obstructive pulmonary disease (COPD), but also bronchiectasis, bronchial asthma, or other less common disorders. Early diagnosis enables AAT augmentation therapy, which has proven to be effective in slowing down functional decline and improving survival rates. This article presents two cases of pregnant women with rare allelic variants of AATD who received AAT augmentation therapy, exploring the limited evidence on its safety during pregnancy and the potential role of decreased serum AAT levels in pregnancy-related complications.
