Study Design: Population-based cohort study.
Objectives: To determine non-modifiable and modifiable risk indicators of acute length of hospital stay (LOHS) after traumatic spinal cord injury (TSCI).
Setting: Government-funded hospitals within the City of Cape Town, South Africa.
Methods: Newly injured survivors of TSCI during a 1 year period were prospectively included. Non-modifiable (e.g., demographic factors and clinical characteristics) and modifiable risk indicators (e.g., clinical processes, timing of surgery, secondary complications) of prolonged LOHS (31 days) were determined using univariate and multivariable logistic regression analyses.
Results: Of the total population-based cohort of 145 individuals, 139 (96%) had valid LOHS data and were included in the analyses. Significant univariate non-modifiable risk indicators of LOHS were age, complete injury and vertebral injury, whereas modifiable risk indicators were delayed spinal surgery (>72 h) and the occurrence of any secondary complications, as well as specifically pressure ulcers, pneumonia and urinary tract infection. In the final multivariable model showing good fit and acceptable discrimination (AUC = 0.86), older age (OR: 1.04, 95% CI: 1.00-1.07), vertebral injury (OR: 3.18, 95% CI: 1.07-9.44), pneumonia (OR: 8.40, 95% CI: 2.76-25.55) and pressure ulcers (OR: 7.16, 95% CI: 2.54-20.22) remained significant independent factors. Only injury completeness was insignificant in the final model.
Conclusions: Our findings shed light on the need of developing prevention programs for secondary complications to improve the quality and efficiency of acute SCI care in South Africa.

Association between gestational age and severe maternal morbidity in preterm delivery: A nationwide population-based cohort study.
Int J Gynaecol Obstet

Department of Obstetrics and Gynecology, Nord Hospital, APHM, Chemin Des Bourrely, Marseille, France.
Objective: This study investigates whether early gestational age (GA) at delivery is associated with an increased risk for severe maternal morbidity (SMM) in women with preterm delivery.
Methods: This retrospective national cohort study based on the Programme de Médicalisation des Systèmes d'Information database included mothers who gave birth between 22 and 37 weeks in metropolitan France in 2019 (in utero deaths and medical terminations of pregnancies were excluded). SMM was defined as a composite criterion consisting of the occurrence of at least one of the following events: death, severe preeclampsia, obstetric surgical complications, severe maternal diseases, and admission to the intensive care unit.
Effect of serotonin receptor gene variants on substance use disorders.

Department of Anatomy, College of Medicine, King Khalid University, Abha, Saudi Arabia.
Background: Substance use disorders are multifaceted conditions influenced by both genetic and environmental factors. Serotonergic pathways are known to be involved in substance use disorder susceptibility, with genetic markers within serotonin receptor genes identified as potential risk factors.
Methods: To further explore this relationship, we conducted a study to investigate the association between several polymorphisms in five serotonin receptor genes (, , ) and substance use disorders (SUD) in Jordanian males by sequencing genotypes in 496 SUD patients and 496 healthy controls.

Department of Gastroenterology, Peking Union Medical College Hospital, Beijing, China.
Objective: To investigate the prevalence of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC), and the impact of comorbidity of AIH, PBC, and PSC on hospitalization burden in patients with inflammatory bowel disease (IBD).
Methods: Inpatients admitted to Peking Union Medical College Hospital from January 1, 1998 to December 31, 2021 were included. Odds ratio (OR) and the corresponding 95% confidence interval (CI) were calculated to compare the risk of AIH, PBC, and PSC between IBD and non-IBD patients.

In a number of causes of Parkinson's disease (PD), occupation is periodically mentioned as a possible risk factor. However, a look at the complex impact of external factors on people of certain professions and the expansion of the area of risk factors in a rapidly changing world leads to the emergence of new studies. There is an assumption that the risk of developing PD is increased in doctors due to long-term exposure to stress.

Chronic cerebral ischemia (CCI) is one of the most common forms of cerebrovascular disease, which affects a significant number of patients, often leading to disability, cognitive impairment and dementia. The analysis of modern data on the pathogenesis and risk factors for the development of CCI, as well as on the mechanisms of action of Mexidol on various links in the pathogenesis of CCI. A systematic search was conducted in the PubMed, MEDLINE and Google Scholar databases, on Russian and English-language sites with open access publications on the problem of CCI and on the drug Mexidol in the period from 2014 to 2024.
