Article Abstract
Excessive oxidative stress resulting from hyperoxia or hypoxia is a recognized risk factor for diseases of prematurity. However, the role of the hypoxia-related pathway in the development of these diseases has not been well studied. Therefore, this study aimed to investigate the association between four functional single nucleotide polymorphisms (SNPs) in the hypoxia-related pathway, and the development of complications of prematurity in relation to perinatal hypoxia. A total of 334 newborns born before or on the 32nd week of gestation were included in the study. The SNPs studied were rs11549465 and rs11549467, rs2010963, and rs833061. The findings suggest that the rs11549465T allele is an independent protective factor against necrotizing enterocolitis (NEC), but may increase the risk of diffuse white matter injury (DWMI) in newborns exposed to hypoxia at birth and long-term oxygen supplementation. In addition, the rs11549467A allele was found to be an independent protective factor against respiratory distress syndrome (RDS). No significant associations with SNPs were observed. These findings indicate the potential involvement of the hypoxia-inducible pathway in the pathogenesis of complications of prematurity. Studies with larger sample sizes are needed to confirm these results and explore their clinical implications.

Background: Mood swings are associated with an elevated risk of preterm birth. However, the causal relationships between them still remain unclear.
Methods: We performed a two-sample Mendelian randomization (MR) analysis to clarify the association between mood swings and preterm birth.
Management of preterm premature rupture of membranes: Antimicrobial stewardship and novel therapeutic strategies.

Department of Obstetrics and Gynecology, The First Affiliated Hospital of Jinan University, Guangzhou, Guangdong Province, China.
Purpose: Preterm premature rupture of membranes (PPROM) is a major contributor to preterm birth and is associated with increased risks of maternal and neonatal complications. The aim of this review is to summarize current antibiotic strategies and explore emerging adjunctive therapies, including probiotics, amnioinfusion, and fetal membrane repair, to improve the management of PPROM.
Methods: Relevant literature on antibiotic therapy for PPROM and emerging treatment strategies was systematically retrieved from PubMed.

Objective: Endometriosis is a chronic gynaecological condition affecting reproductive-aged women. It has been associated with infertility and potential risks for adverse pregnancy outcomes, although population-level evidence remains limited.
Methods: This retrospective cohort study, including 147,950 pregnant women aged 20-45 years, used nationwide population-based data to compare the outcomes between women with (n = 11,400) and without (n = 136,550) endometriosis between 2000 and 2021.

Background: Acute upper gastrointestinal bleeding (AUGIB) is a critical medical emergency and is a common cause of illness and death in individuals with liver cirrhosis.
Objective: The point of this study was to check how well the albumin-to-bilirubin ratio (ALBI) and model for end-stage liver disease (MELD) scores could predict how these patients would do in the future.
Methods: The Imam Khomeini Hospital gastroenterology department conducted a retrospective examination.
Sudden Death Caused by Bilateral Diaphragmatic Eventration in Myotonic Dystrophy Type 1.

Myotonic dystrophy type 1, or dystrophia myotonica type 1 (DM1), is a multisystem disorder inherited in an autosomal dominant manner. It is caused by a CTG tri-nucleotide expansion in the 3'-untranslated region (3'-UTR) of the dystrophia myotonia protein kinase (DMPK) gene. Core clinical features include progressive skeletal muscle weakness, myotonia, and systemic complications, with premature mortality most often due to respiratory or cardiac dysfunction.
