Exploring factors influencing COVID-19 severity: a matched case-control study.

Objective: COVID-19, first identified in December 2019, quickly became a global pandemic and remains a significant public health concern. Robust data is rare, especially in pregnant women. The symptoms of this disease range from mild to severe respiratory distress syndrome and mortality.

Synthesis and Characterization of a Hercynite-Supported Copper(II) Complex Based on 1,10-Phenanthroline-5,6-dione and Acetylacetone Building Blocks and Its Catalytic Application in Annulation Reactions.

In the present work, a novel Cu(II) complex containing 10-phenanthroline-5,6-dione (phen-dione) and acetylacetone (acac) was prepared via solid-phase synthesis on silica-modified hercynite magnetic nanoparticles (MNPs). The resulting structure underwent thorough structural analysis using diverse instrumental techniques. The catalytic potential of the synthesized Cu(II) complex was successfully demonstrated in the synthesis of 2-amino-3-cyano-4-chromenes.

Comparison of three umbilical entry sites for intraperitoneal access by the direct trocar insertion technique: a randomized pilot study.

Objective: The most effective methods and entry sites for laparoscopic surgery remain a subject of ongoing investigation and discussion. The purpose of the study was to analyze and compare three umbilical entry sites for intraperitoneal access using the direct trocar insertion technique.

Material And Methods: A randomized pilot study was conducted between March 2021 and January 2023, involving women eligible for laparoscopic gynecological surgery.

Neuropelveology for Endometriosis Management: A Systematic Review and Multilevel Meta-Analysis.

: Despite the availability of treatments such as surgery and hormonal therapy, women with endometriosis often endure chronic problems. This review aims to evaluate the effectiveness and safety of neuropelveology. : In a systematic review with a meta-analysis, we searched three electronic databases: MEDLINE (PubMed), Scopus, Embase, and Web of Science (WOS).

LHHW/RSM reaction rate modeling for Co-Mn/SiO nanocatalyst in Fishcher-Tropsch synthesis.

This study aims to assess the kinetics of Fischer-Tropsch (FT) reaction over the cobalt-manganese nanoparticles supported by silica oxide. Nanoparticles were synthesized by the thermal decomposition method using "[Co(NH)CO]MnO" complex and characterized by XRD, TEM, and BET techniques. The kinetics of the process were evaluated using a combination of Langmuir-Hinshelwood-Hougen-Watson (LHHW) and response surface methodology.
