Brucellosis is a serious public health problem worldwide and can affect any organ system. Due to brucellosis's variable clinical presentation, ranging from subclinical to fully symptomatic, and limited available information, it poses a diagnostic challenge. In this study, we reported a case series of patients with diverse presentations. In addition, we briefly described the pathophysiology and mechanisms of Brucella in the body. These case presentations will be valuable in increasing the awareness of physicians. A prompt diagnosis is crucial, as detecting some clues of the infection in its early stages can help avoid misdiagnoses.

Background: As metabolic dysfunction-associated steatotic liver disease (MASLD) management extends into primary care, little is known about patterns of specialty referral for affected patients. We determined the proportion of primary care patients with MASLD that received a gastroenterology (GI) consultation and compared advanced fibrosis risk between patients with and without a referral.
Methods: This retrospective study of electronic health record data from a primary care clinic included patients with MASLD, no competing chronic liver disease diagnoses, and no history of cirrhosis. Referral to GI for evaluation and management (E/M) any time after MASLD ascertainment was the outcome. Fibrosis-4 Index (FIB-4) scores were calculated, categorized by advanced fibrosis risk, and compared by receipt of a GI E/M referral. Logistic regression models were developed to determine the association of FIB-4 risk with receipt of a GI referral.
Results: The cohort included 652 patients of which 12% had FIB-4 scores (≥2.67) at high-risk for advanced fibrosis. Overall, 31% of cohort patients received a GI referral for E/M. There was no difference in the proportion of patients with high (12% vs. 12%, p=0.952) risk FIB-4 scores by receipt of a GI E/M referral. In adjusted logistic regression models, high-risk FIB-4 scores (OR 1.01; 95% CI 0.59 - 1.71) were not associated with receipt of a referral.
Conclusions: Only 30% of patients in this primary care MASLD cohort received a GI E/M referral during the study period, and those patients with a referral did not differ by FIB-4 advanced fibrosis risk.

Background: Despite the high incidence of sarcopenia in systemic sclerosis (SSc) patients, there is currently limited evidence on their outcomes.
Objectives: Our study aimed to determine clinical courses, outcomes, and identify factors associated with mortality in the SSc patients with sarcopenia.
Methods: A historical cohort study was conducted in 180 adult SSc patients diagnosed with sarcopenia according to the criteria of Asian Working Group for Sarcopenia 2019, who were attending the Scleroderma Clinic at Khon Kaen University between July 2019 and November 2021.
Results: Forty-one were diagnosed with sarcopenia. A total of 443.8 persons-year, the respective mortality rate for SSc patients with and without sarcopenia was 5.05 and 5.22 per 100-person-years, showing no statistical difference (p = 0.58). Sarcopenia was not a significant mortality risk in SSc patients with a hazard ratio (HR) of 1.34, 95 % CI 0.48-3.75. The survival rate from the baseline evaluation of sarcopenia to the last follow-up of the patients with sarcopenia at 6-, 12-, 18-, and 24-months were 97.6 %, 95.1 %, 92.7 %, and 87.8 %. Hospitalization was the sole factor significantly associated with the mortality risk, with a HR of 14.21 (95 % CI 2.36-85.60). Sarcopenia itself did not appear to be a significant predictor of disease progression, it did contribute significantly to the progression of salt and pepper skin (p=0.01).
Conclusions: The mortality rate of SSc patients with sarcopenia increased after a 2-year follow-up but no difference from non-sarcopenic patients. Once these patients required hospitalization, the mortality risk increased by over 10 times. Further long-term follow-up in a large cohort is suggested.

Background: The purpose was to explore the correlation between refeeding hypophosphatemia and delirium and analyze the related factors in critically ill patients.
Methods: We conducted a retrospective review of critically ill patients admitted to Nanjing Drum Tower Hospital between September 2019 and March 2021. The patients were divided into delirium and nondelirium groups. Demographic data, underlying diseases, laboratory findings, comorbidities, nutritional intake and overall prognosis were collected and analyzed.
Results: In total, 162 patients were included and divided into delirium (n=54) and nondelirium (n=108) groups. Serum phosphorus levels in the two groups decreased significantly in the first three days (P1, P2, P3) after nutrient intake compared with baseline before nutrient intake (Ppre). P1 and P2 were significantly lower in the delirium group compared to the nondelirium group. The maximum blood phosphorus reduction (Pmax) in the first three days after nutrient intake was significantly higher in the delirium group than in the nondelirium group. The time of Pmax in the delirium group was on the first day after nutrient intake. Multivariable logistic regression analysis identified starting route of nutrition and P1< 0.845 mmol/L as the independent predictors of delirium development in critically ill patients.
Conclusion: The incidence of delirium in critically ill patients is high and associated with refeeding hypophosphatemia. Delirium may occur with serum phosphorus levels less than 0.845 mmol/L on the first day.

Chronic Obstructive Pulmonary Disease (COPD) is a complex pulmonary condition characterized by chronic airflow limitation. Within the spectrum of COPD, distinct overlap conditions exist, including Asthma-COPD Overlap (ACO), COPD-Obstructive Sleep Apnea (COPD-OSA), Combined Pulmonary Fibrosis and Emphysema (CPFE), and Bronchiectasis-COPD Overlap (BCO). This review provides a comprehensive overview of the clinical and therapeutic implications of these conditions, highlighting the differences in complications compared with COPD alone in addition to the diagnostic challenges of identifying these conditions. Therapeutically tailored approaches are necessary for COPD overlap conditions considering the unique complications that may arise. Optimal pharmacological management, disease-specific interventions, and comprehensive patient-centered care are crucial components of treatment strategies. This review provides insights for healthcare professionals by enhancing their understanding and management of these conditions. This emphasizes the importance of accurate diagnosis and individualized treatment plans, considering the specific complications associated with each COPD overlap condition.

Background: Whether Astragalus membranaceus is an effective drug in treatment of ulcerative colitis (UC) and how it exhibit activity effect on UC is unclear.
Methods: TCMSP, GeneCards, String, and DAVID database were used to screening target genes construct PPI network and performed for GO and KEGG pathway enrichment analysis respectively. Molecular docking and animal experiment were performed. The body weight and disease activity index (DAI) of mice were recorded. ELISA kits were used to detect the levels of CAT, SOD, MDA and IL-6, IL-10, TNF-α in the blood of mice. Western blot kits were utilized to measured the expressions of MAPK14, RB1, MAPK1, JUN, ATK1, and IL2 proteins.
Results: The active components of Astragalus membranaceus mainly including 7-O-methylisomucronulatol, quercetin, kaempferol, formononetin and isrhamnetin. Astragalus membranaceus may inhibited the expression of TNF-α, IL-6, MDA, and promoted the expression of CAT, SOD, IL-10. The expression levels of MAPK14, RB1, MAPK1, JUN and ATK1 proteins were significantly decreased while IL2 protein increased administrated with Astragalus membranaceus.
Conclusions: Astragalus membranaceus is an effective drug in treatment of UC according to related to above targets that may exhibits the anti-UC effect via its antioxidant pathway and regulating the balance of pro-inflammatory and anti-inflammatory factors.
背景:黄芪是治疗溃疡性结肠炎(UC)的有效药物吗?黄芪是否是治疗溃疡性结肠炎(UC)的有效药物及其对UC的活性作用尚不清楚:方法:利用 TCMSP、GeneCards、String 和 DAVID 数据库筛选构建 PPI 网络的靶基因,并分别进行 GO 和 KEGG 通路富集分析。进行了分子对接和动物实验。记录小鼠的体重和疾病活动指数(DAI)。用 ELISA 试剂盒检测小鼠血液中 CAT、SOD、MDA 和 IL-6、IL-10、TNF-α 的水平。用Western印迹试剂盒检测MAPK14、RB1、MAPK1、JUN、ATK1和IL2蛋白的表达:结果:黄芪的有效成分主要包括7-O-甲基异黄芪醇、槲皮素、山柰醇、甲萘素和异鼠李素。黄芪可抑制 TNF-α、IL-6、MDA 的表达,促进 CAT、SOD、IL-10 的表达。服用黄芪后,MAPK14、RB1、MAPK1、JUN和ATK1蛋白的表达水平明显下降,而IL2蛋白的表达水平上升:根据上述靶点,黄芪是一种治疗UC的有效药物,可通过其抗氧化途径和调节促炎因子与抗炎因子的平衡发挥抗UC作用。
