Background: The consequences of severe acute respiratory syndrome corona virus 2 on mother and fetus remain unknown due to a lack of robust evidence from prospective studies.
Purpose: This study evaluated the effect of coronavirus disease 2019 (COVID-19) on neonatal outcomes and the scope of vertical transmission.
Methods: This ambispective observational study enrolled pregnant women with COVID-19 in North India from April 1 to August 31, 2020 to evaluate neonatal outcomes and the risk of vertical transmission.
Results: A total of 44 neonates born to 41 COVID-19-positive mothers were evaluated. Among them, 28 patients (68.3%) (2 sets of twins) were delivered within 7 days of testing positive for COVID-19, 23 patients (56%) (2 sets of twins) were delivered by cesarean section; 13 newborns (29.5%) had low birth weight; 7 (15.9%) were preterm; and 6 (13.6%) required neonatal intensive care unit admission, reflecting an increased incidence of cesarean delivery and low birth weight but zero neonatal mortality. Samples of cord blood, placental membrane, vaginal fluid, amniotic fluid, peritoneal fluid (in case of cesarean section), and breast milk for COVID-19 reverse transcription-polymerase chain reaction tested negative in 22 prospective delivery cases. Nasopharyngeal swabs of 2 newborns tested positive for COVID-19: one at 24 hours and the other on day 4 of life. In the former case, biological samples were not collected as the mother was asymptomatic and her COVID-19 report was available postdelivery; hence, the source of infection remained inconclusive. In the latter case, all samples tested negative, ruling out the possibility of vertical transmission. All neonates remained asymptomatic on follow-up.
Conclusion: COVID-19 does not have direct adverse effects on the fetus per se. The possibility of vertical transmission is almost negligible, although results from larger trials are required to confirm our findings.

Faced with the increased frequency of zoonotic spillover in recent decades, emerging vector-borne diseases from nonhuman primates pose a significant threat to global public health. Understanding transmission dynamics driven by arthropod vectors between wildlife populations is critical for surveillance, modeling, and mitigation. Elevated canopy-level sampling is a valuable approach for elucidating vector behavior and sylvatic transmission.

Three-dimensional vertically stacked memory is more cost-effective than two-dimensional stacked memory. Vertically stacked memory using ferroelectric materials has great potential not only in high-density memory but also in neuromorphic fields because it secures low voltage and fast operation speed. This paper presents the implementation of a ferroelectric capacitor comprising a vertical two-layer stacked structure composed of a titanium nitride (TiN)/aluminum-doped hafnium oxide/TiN configuration.

Background: Retesting for HIV during pregnancy, labor, and postpartum is crucial for identifying new infections and ensuring timely interventions to prevent mother-to-child transmission (PMTCT). Uganda's national guidelines recommend that pregnant women be retested in the 3rd trimester or during labor/delivery. However, limited information exists regarding adherence to these guidelines, which may affect the effectiveness of PMTCT efforts.

The global strategy to #EndAIDS is underpinned by a call to end all inequities and to ensure no-one is left behind; but inequities continue, and people are still being left behind. Despite the advances seen in some populations and in some geographical areas, with ongoing high rates of HIV vertical transmission, ending HIV for pregnant and breastfeeding women and their children must be prioritised urgently. Focused on Asia and the Pacific, the region with the second largest number of people with HIV, in this viewpoint we highlight the heterogenous nature of global and regional success in eliminating vertical transmission of HIV.

Streptococcus suis (S. suis) is a major pathogen for pigs, causing large economic losses to the swine industry. Moreover, this bacterium has a zoonotic potential, being capable of infecting humans in close contact with pigs or, less frequently, through contact with pork products.
