Observational Study
Association between serum vitamin D, uric acid, C-reactive protein, and disease severity in ulcerative colitis: A retrospective study.
Ulcerative colitis (UC) is an inflammatory disease of the intestinal mucosa, and immunodeficiency is the main cause. Vitamin D (VD) has been shown to regulate many immune diseases, and studies have found that the level of uric acid (UA) and C-reactive protein (CRP) may also affect the severity of UC. This study aimed to investigate the correlation between VD levels and disease severity in UC patients. ⋯ Gender affects serum UA, CRP, and disease severity. Males have significantly higher serum UA and CRP levels than females, while disease severity is generally lower than that of females. However, the mechanism of abnormal serum vitamin and trace element levels in UC patients remains to be further studied.

Observational Study
Is detrusor underactivity the urodynamic characteristic of long-COVID in patients with benign prostate hyperplasia?
Although coronavirus disease 19 (COVID-19) was reported to involve with multiple organs, COVID-19 reports focusing on urinary system mostly evaluated the association between lower urinary tract symptoms and COVID-19 using questionnaire score. In this study, sonography video urodynamic studies was first conducted to explore the effects of COVID-19 on contractility of bladder detrusor of patients with benign prostate hyperplasia (BPH). Clinical data was respectively reviewed and compared between BPH patients with previous COVID-19 infection (COVID-19 group) and without previous COVID-19 (non-COVID-19 group). ⋯ Post-voiding residual urine was found to have a linear correlation with detrusor contractility in COVID-19 group. It was suggested that COVID-19 infection would further exacerbate impairment of detrusor previously resulted from bladder outlet obstruction in BPH patients. DU may be a urodynamic characteristic of long-COVID.

Metagenomic next-generation sequencing (mNGS) is a new high-throughput sequencing method that may have great importance in early diagnosis and clinical management of sepsis. This study aimed to detect the difference between mNGS and comprehensive routine microbiological test (CMT), and to explore the diagnostic efficacy of mNGS in septic patients. This study retrospectively analyzed 150 sepsis patients who were admitted to the intensive care units of 4 hospitals in Southwest China from October 1, 2018, to October 1, 2021, and underwent both blood mNGS and CMT. ⋯ Bronchoalveolar lavage fluid constituted 58.7%, blood 56.0%, with other specimens including pleural fluid at 29.3%, pus at 19.3%, swabs at 9.3%, cerebrospinal fluid at 8.7%, tissue at 6.0%, and bone marrow at 5.3%. mNGS demonstrated a diagnostic accuracy of 56.0% for sepsis, with a sensitivity of 84.4%, specificity of 26.0%, a positive predictive value of 54.6%, a negative predictive value of 61.3%. Metagenomic testing enables the rapid and early identification of infectious pathogens in sepsis patients, especially fungi and viruses. The study found that mNGS has high sensitivity in diagnosing sepsis patients, particularly for fungal and viral infections. mNGS technology is beneficial for critically ill sepsis patients.

Case Reports
Bilateral carotid and vertebral rete mirabile with aneurysm misdiagnosed as Moyamoya disease: A case report.
Rete mirabile (RM) is rare in humans, normally existing in lower mammalian arteries. To study its clinical and imaging features, we report an extremely rare case that occurred in humans and review the literature. ⋯ RM involving in both anterior and posterior circulation is an extremely rare clinical abnormality of cerebrovascular morphology. The radiologists and clinicians should deepen their awareness of the specific CTA feature of RM. When individual CTA examination is insufficient, the utility of digital subtraction angiography is crucial for making a clear diagnosis.

Higher erythrocytes in cerebrospinal fluid on the first and seventh postoperative day: Associated with poor outcome in aneurysmal subarachnoid hemorrhage patients.
Aneurysmal subarachnoid hemorrhage is an acute cerebrovascular disease with high disability and mortality. We intended to explore the association between levels of erythrocytes in cerebrospinal fluid at different times of hemorrhage and the outcome of patients. One retrospective study including 216 patients with aneurysmal subarachnoid hemorrhage undergoing surgeries in the First Affiliated Hospital of Yangtze University from January 2020 to July 2023 was carried. ⋯ The multivariable logistic regression analysis results showed that erythrocytes in cerebrospinal fluid on the 1st postoperative day (≥177 × 103/µL) and on the 7th postoperative day (≥53.5 × 103/µL) were possibly associated with poor outcome in aneurysmal subarachnoid hemorrhage patients. Treatment with tranexamic acid and continuous lumbar drainage did not result in a decrease of erythrocytes in cerebrospinal fluid. Higher erythrocytes in cerebrospinal fluid on the 1st and 7th postoperative days were associated with poor outcome in aneurysmal subarachnoid hemorrhage patients.
