Summary: This study investigated the association between the composition of the vaginal microbiota and the activation and regulation of the complement system during pregnancy and labor. The results showed that the dominant Lactobacillus species in the vaginal microbiota were correlated with complement activation, and the abundance of different bacteria varied during pregnancy and labor. The findings indicate that the bacterial composition of the vaginal microbiota may play a role in the local activation and regulation of complement-mediated inflammation during pregnancy.

Summary: A study found that elevated levels of 60 and 70-KDa extracellular heat shock proteins (eHsp) and decreased levels of eHsp-27 in the first trimester are associated with the development of preeclampsia (PE). These findings suggest that first-trimester eHsp levels may serve as early biomarkers for predicting PE.

Summary: The study identified furin as a key player in promoting uterine activation for labor at term. Inhibition of furin activity suppressed contraction in smooth muscle cells and affected the expression of various proteins related to labor. Additionally, TWEAK was found to be a potential substrate for furin regulation of parturition initiation.

Summary: The complement system plays a crucial role in host defense and immunity during pregnancy. Imbalanced complement activation and regulation are associated with complications like preeclampsia. Inhibiting the terminal complement pathway, possibly through C5 blockade, may be an effective strategy for treating these complications.

Summary: Preeclampsia is a significant cause of maternal and perinatal morbidity and mortality worldwide. Its pathogenesis is associated with an excessive maternal inflammatory response and complement activation. Elevated levels of Willebrand factor antigen and decreased ADAMTS-13 activity are related to the progression and diagnosis of the disease.

Summary: S100 proteins bind Ca2+ and regulate signaling pathways, their increased expression levels are associated with various diseases. S100 proteins can be found in high levels in serum and body fluids in pathological states, making them potential diagnostic markers. In addition, S100 protein expression is related to pregnancy and may play a role in embryo/fetus formation.

Summary: Parturition signals the end of immune tolerance in pregnancy. The activation of placental inflammasome differs in terms of mode of delivery and neonatal sex. Assessing placental inflammasome activation may identify babies who have been exposed to aberrant inflammation at birth.

Summary: The study found that levels of adipsin, C5a, and sENG were significantly increased in the plasma of pregnant women with preeclampsia before delivery. In healthy pregnant women, levels of adipsin, C5a, and sENG increased from the third trimester and remained stable postpartum, but C3a levels increased in the second trimester and remained stable afterward.

Summary: The dosage and timing of aspirin initiation are crucial for reducing the risk of preeclampsia. Initiating a dosage of >100 mg of aspirin daily before 16 weeks' gestation seems to be the most effective approach. Randomized control trials are needed to evaluate the safety and efficacy of different aspirin dosages available in the United States.

Summary: This study proposes the use of pregnancy-specific reference intervals (RIs) to interpret investigations during pregnancy, with the aim to improve diagnostic accuracy by using gestational age-specific RIs. By mapping the trajectory of platelets in pregnant women, it is found that platelets below the 3rd centile in early pregnancy can accurately predict thrombocytopaenia at term.

Summary: Despite progress in fighting infectious diseases, human adenoviruses (HAdVs) that cause eye infections still pose a significant threat. Conventional diagnostic methods suffer from various issues, and this study presents a novel nanobased immunosensing technique for rapid HAdV detection. The developed assay is simple, reliable, and cost-effective, with a detection limit of 10(2) pfu/mL in less than 2 minutes. It offers a visual color change as a means of detection, demonstrating high specificity and potential as a point-of-care testing device for low-resource settings.

Summary: This retrospective cohort study analyzed E6, E7, and L1 gene mutations in cervical specimens collected from Saudi women positive for HPV16 or HPV18 infection. The study found that HPV16 and HPV18 lineages in these specimens were predominantly from Europe. Certain mutations in the E6 and E7 genes of HPV16 were associated with cervical cancer progression and low risk, respectively. Other specific HPV16 and HPV18 mutations were associated with increased risk of cancer, progression, viral load, and age. These findings have important implications for the design of molecular diagnostic tests and vaccination strategies for the Saudi population.

Summary: This study identified mutations in the nucleocapsid protein of SARS-CoV-2 and their association with patient characteristics. Among the identified mutations, R203K was the most common and was associated with reduced risk of ICU admission and death. On the other hand, D63G, R203M, and D377Y were associated with increased risk of ICU admission. The findings highlight the importance of monitoring nucleocapsid protein mutations in understanding viral infection and disease severity.

Summary: The aim of this study was to assess the impact of Omicron subvariants on the mortality of transplant recipients. Our findings revealed that the mortality rate of transplant patients infected with Omicron variants was higher in our cohort compared to other centers, as a limited number of patients received booster vaccines. Optimizing booster vaccination is the most efficient way to improve the mortality of COVID-19 in transplant recipients.

Summary: This study evaluated the efficacy and safety of the combination therapy of casirivimab and imdevimab in patients hospitalized with COVID-19. The results showed that this combination therapy reduced the 28-day mortality rate in patients without detectable antibodies to SARS-CoV-2 infection at baseline, but not in those with detectable antibodies.
