OBJECTIVE To offer a reference for the treatment of Mycobacterium iranicum infection by analyzing the diagnosis and management of a single case alongside literature-reported cases. METHODS Through case report and literature reviews, this study synthesized the clinical features, therapeutic regimens, and patient outcomes of those infected with M. iranicum. RESULTS In the single case documented in this report, subsequent to clinical pharmacists’ involvement in the consultation, the patient was prescribed a therapeutic regimen comprising levofloxacin (0.5 g, qd, ivgtt)+Clarithromycin sustained-release tablets (1 000 mg, qd, po) + Ethambutol tablets (0.75 g, qd, po). The patient exhibited clinical improvement and was discharged after treatment. This article integrated 12 published studies, encompassing 13 patients (7 male and 6 female), of whom 69.23% were aged ≥50 years. Patients infected with M. iranicum exhibited non-specific clinical manifestations and imaging features, with pulmonary infection as the primary presentation. Antimicrobial susceptibility test revealed that M. iranicum was susceptible to multiple agents, including amikacin, clarithromycin, linezolid, and ethambutol. The three-drug combination therapy was the most frequently employed regimen. In terms of clinical outcomes, there were 9 cases (69.23%) of clinical cure, 3 cases (23.08%) of bacteriological negativity conversion, and 1 case (7.69%) of treatment failure. CONCLUSIONS For M. iranicum infection, a triple-drug therapeutic regimen consisting of three agents with distinct mechanisms of action selected from amikacin, clarithromycin, moxifloxacin, levofloxacin, minocycline, ethambutol, and other relevant drugs may represent a relatively optimal strategy.

Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.

Objective:To study the application of conicity index (CI),body mass index (BMI),waist-to-hip ratio (WHR) and body fat ratio (BFR) in abdominal obesity in maintenance hemodialysis (MHD) patients. Methods The patients who received dialysis treatment in the hemodialysis center of the Third Affiliated Hospital of Chongqing Medical University from September to December 2023 were selected by fixed-point cluster sampling,and the age,dialysis age,height,weight,biochemical examination indexes and other information of the study subjects were collected,and the body composition analysis was performed using InBody S10 and the visceral fat area was used as the basis for the determination of abdominal obesity. The applications of body mass index,body fat ratio,waist-to-hip ratio and conicity index in predicting abdominal obesity in MHD patients were compared. Results A total of 151 patients were enrolled,including 65 patients with abdominal obesity MHD and 86 patients with non-abdominal obesity MHD. The results showed that there were significant differences in gender,weight,BMI,visceral fat area,body fat ratio,waist-to-hip ratio,conicity index and the prevalence of diabetes between patients with abdominal obesity and non-abdominal obesity (all P<0.05). The consistency test results showed that the consistency between using BMI,body fat percentage,and waist hip ratio to determine abdominal obesity with visceral fat area method was weak,with the conicity index Kappa coefficient having the largest value (P<0.05).The analysis of receiver operating characteristic (ROC) curve showed that the area under the ROC curve of conicity index was the highest,0.765,indicating the highest diagnostic efficacy (P<0.05) in MHD patients. Conclusion Conicity index,body mass index,waist-to-hip ratio and body fat ratio can be used in the diagnosis of abdominal obesity in MHD patients,among which the conicity index is more effective.

Objective China is among the 30 countries with a high burden of tuberculosis(TB)worldwide,and TB remains a public health concern.Kashgar Prefecture in the southern Xinjiang Autonomous Region is considered as one of the highest TB burden regions in China.However,molecular epidemiological studies of Kashgar are lacking. Methods A population-based retrospective study was conducted using whole-genome sequencing(WGS)to determine the characteristics of drug resistance and the transmission patterns. Results A total of 1,668 isolates collected in 2020 were classified into lineages 2(46.0%),3(27.5%),and 4(26.5%).The drug resistance rates revealed by WGS showed that the top three drugs in terms of the resistance rate were isoniazid(7.4%,124/1,668),streptomycin(6.0%,100/1,668),and rifampicin(3.3%,55/1,668).The rate of rifampicin resistance was 1.8%(23/1,290)in the new cases and 9.4%(32/340)in the previously treated cases.Known resistance mutations were detected more frequently in lineage 2 strains than in lineage 3 or 4 strains,respectively:18.6%vs.8.7 or 9%,P<0.001.The estimated proportion of recent transmissions was 25.9%(432/1,668).Multivariate logistic analyses indicated that sex,age,occupation,lineage,and drug resistance were the risk factors for recent transmission.Despite the low rate of drug resistance,drug-resistant strains had a higher risk of recent transmission than the susceptible strains(adjusted odds ratio,1.414;95%CI,1.023-1.954;P = 0.036).Among all patients with drug-resistant tuberculosis(DR-TB),78.4%(171/218)were attributed to the transmission of DR-TB strains. Conclusion Our results suggest that drug-resistant strains are more transmissible than susceptible strains and that transmission is the major driving force of the current DR-TB epidemic in Kashgar.

Objective Studies on the relationship between iodine,vitamin A(VA),and vitamin D(VD)and thyroid function are limited.This study aimed to analyze iodine and thyroid-stimulating hormone(TSH)status and their possible relationships with VA,VD,and other factors in postpartum women. Methods A total of 1,311 mothers(896 lactating and 415 non-lactating)from Hebei,Zhejiang,and Guangxi provinces were included in this study.The urinary iodine concentration(UIC),TSH,VA,and VD were measured. Results The median UIC of total and lactating participants were 142.00 μg/L and 139.95 μg/L,respectively.The median TSH,VA,and VD levels in all the participants were 1.89 mIU/L,0.44 μg/mL,and 24.04 ng/mL,respectively.No differences in the UIC were found between lactating and non-lactating mothers.UIC and TSH levels were significantly different among the three provinces.The rural UIC was higher than the urban UIC.Obese mothers had a higher UIC and a higher prevalence of excessive TSH.Higher UICs and TSHs levels were observed in both the VD deficiency and insufficiency groups than in the VD-sufficient group.After adjustment,no linear correlation was observed between UIC and VA/VD.No interaction was found between vitamins A/D and UIC on TSH levels. Conclusion The mothers in the present study had no iodine deficiency.Region,area type,BMI,and VD may be related to the iodine status or TSH levels.

Background::Acute pulmonary embolism (APE) is a fatal cardiovascular disease, yet missed diagnosis and misdiagnosis often occur due to non-specific symptoms and signs. A simple, objective technique will help clinicians make a quick and precise diagnosis. In population studies, machine learning (ML) plays a critical role in characterizing cardiovascular risks, predicting outcomes, and identifying biomarkers. This work sought to develop an ML model for helping APE diagnosis and compare it against current clinical probability assessment models.Methods::This is a single-center retrospective study. Patients with suspected APE were continuously enrolled and randomly divided into two groups including training and testing sets. A total of 8 ML models, including random forest (RF), Na?ve Bayes, decision tree, K-nearest neighbors, logistic regression, multi-layer perceptron, support vector machine, and gradient boosting decision tree were developed based on the training set to diagnose APE. Thereafter, the model with the best diagnostic performance was selected and evaluated against the current clinical assessment strategies, including the Wells score, revised Geneva score, and Years algorithm. Eventually, the ML model was internally validated to assess the diagnostic performance using receiver operating characteristic (ROC) analysis.Results::The ML models were constructed using eight clinical features, including D-dimer, cardiac troponin T (cTNT), arterial oxygen saturation, heart rate, chest pain, lower limb pain, hemoptysis, and chronic heart failure. Among eight ML models, the RF model achieved the best performance with the highest area under the curve (AUC) (AUC = 0.774). Compared to the current clinical assessment strategies, the RF model outperformed the Wells score ( P = 0.030) and was not inferior to any other clinical probability assessment strategy. The AUC of the RF model for diagnosing APE onset in internal validation set was 0.726. Conclusions::Based on RF algorithm, a novel prediction model was finally constructed for APE diagnosis. When compared to the current clinical assessment strategies, the RF model achieved better diagnostic efficacy and accuracy. Therefore, the ML algorithm can be a useful tool in assisting with the diagnosis of APE.
