Effects of body mass index on mortality in elderly patients with hip fractures.
Hip fractures remain a substantial health concern, particularly among elderly individuals with osteoporosis, leading to high global mortality rates. This study aimed to analyze the association between body mass index (BMI) and postoperative mortality in patients who underwent surgery for hip fractures. A total of 680 patients treated at a single institution between January 2018 and December 2022 were included. ⋯ Underweight status, male sex, higher CCI, and general anesthesia were significantly associated with 1-year and in-hospital mortality. Notably, underweight individuals exhibited a higher risk of mortality than normal-weight individuals, and female patients had lower mortality rates. This study underscores the importance of considering BMI, along with other demographic and clinical factors, in predicting postoperative mortality among patients with hip fractures, aiding the development of tailored management strategies to improve outcomes and reduce complications in this vulnerable patient population.

Nocardiosis is an unusual infection caused by aerobic gram-positive bacteria in the genus Nocardia. Infections resulting from Nocardia species are frequent in immunosuppressive patients. Weakened immune systems caused by human immunodeficiency virus infection, diabetes, cancer, and other conditions such as chronic lung disease, renal failure, etc, are the main risk factors for nocardiosis. Central nervous system (CNS) nocardiosis has been reported to represent ~2% of all and to be present in 15% to 50% of patients with systemic infection. The patient in our case had an isolated CNS nocardiosis caused by Nocardia terpenica infection, a rare reclassified Nocardia pathogen of CNS nocardiosis. ⋯ In this case, the clinical, radiological, and microbiological findings highlight the importance of suspecting Nocardia as the potential pathogen in patients with central nervous system inflammation of doubted immune incompetence. In addition, next-generation sequencing as an effective test is also highly recommended for suspicious CNS infection patients to perform a rapid diagnosis and treatment.

Case Reports
A acute pontine infarction with one-and-a-half syndrome as the manifestation: A case report.
Sudden ocular dyskinesia is usually associated with ophthalmic diseases and rarely with cerebrovascular diseases. This is a rare case of a patient with a sudden onset of ocular dyskinesia due to occlusion of the anterior inferior cerebellar artery and the spiral modiolar artery. This article describes eye movement disorders associated with cerebrovascular disease, aiming to improve our understanding of cerebrovascular diseases and improve the ability of early diagnosis and differential diagnosis. ⋯ Eye movement disorders are sometimes an early warning sign of impending vertebrobasilar ischemic stroke. Patients with acute ischemic stroke who have early detection of oculomotor disturbances should be promptly imaged, as missed diagnosis may lead to serious consequences or even death. It provided us with a new diagnostic idea.

Influence of male body mass index on semen analysis parameters and in vitro fertilization outcomes.
Concurrent global increase of prevalence of obesity and male fertility implies link between overweight and obesity with male subfertility. This hypothesis is supported by numerous population-based epidemiological studies. Increase in body mass index (BMI) is associated with poor sperm quality in fertile, and more noticeable in infertile men. ⋯ The number and proportion of good quality embryos is significantly lower in overweight and obese study groups compared to normal weight and underweight groups (2.89, 2.91, 2.42, and 2.36, respectively, P = .041). The differences in other IVF outcomes: total number of embryos (3.61, 3.74, 3.21, and 3.37, respectively) and clinical pregnancy rates (41.26%, 43.09%, 42.78%, and 39.95%, respectively) between study groups were not significant (P > .05). BMI does not significantly affect semen analysis parameters, but a higher BMI is associated with a lower number and proportion of good quality embryos in IVF outcomes.

Observational Study
Predicting septic shock in obstructive pyelonephritis associated with ureteral stones: A retrospective study.
To identify the best combination of potential predictors of septic shock in patients with obstructive acute pyelonephritis associated with ureteral stones (OAPN-US) according to Sepsis-3 criteria. Patients who underwent percutaneous nephrostomy (PCN) with OAPN-US were retrospectively evaluated. Recursive feature elimination (RFE) was applied to patients with and without septic shock to identify factors associated with the prediction of progression to septic shock. ⋯ Of the 3 variables, PCT had the highest Gini importance score, indicating that it was the most influential factor. Clinical characteristics were different between the SS and the NSS groups. In patients with OAPN-US, the combination of PCT, ALC, and INR was an excellent predictor of septic shock.
