In our study, we developed a ViT model using a diverse set of stained renal histopathology images to evaluate its effectiveness in classifying renal pathology. A total of 1861 whole slide images (WSI) stained with HE, MASSON, PAS, and PASM were collected from 635 patients.

We employed the classic ViT model from the Timm library, utilizing images sized 384 × 384 pixels with 16 × 16 pixel patches, to train the classification model. A comparative analysis was conducted to evaluate the performance of the ViT model against traditional convolutional neural network (CNN) models. The results indicated that the ViT model demonstrated superior recognition ability (accuracy: 0.96-0.99). Furthermore, we visualized the identification process of the ViT models to investigate potentially significant pathological ultrastructures.

A random-effect meta-analysis model was computed to estimate the pooled results. The heterogeneity of the studies was assessed using I&lt;sup&gt;2&lt;/sup&gt; and Cochran's Q.

The subgroup analysis showed the highest prevalence of urolithiasis was found in Mauritian, 28.1% (95%CI 24.5, 31.7), followed by Ethiopia 18.1%, and the lowest was in Eritrea, 1.0%. A sensitivity analysis using the random-effects model found no influential study on the pooled prevalence of urolithiasis.

Although hospital mortality was comparable to that of the control group, long-term mortality remained high. The serum albumin concentration and Charlson Comorbidity Index score emerged as robust predictors of long-term mortality, highlighting the importance of comprehensive risk assessment in this population. The lack of an association between acute kidney injury and mortality suggests the need for further research to understand the complex interplay of factors influencing outcomes in this patient population.</p>","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":"25 1","pages":"336"},"PeriodicalIF":2.2,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11463142/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142387913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This multiple drug use can lead to several drug-related problems including adverse drug events, hospital admissions, poor medication adherence, harmful drug interactions, inadequate therapeutic outcomes, and death. Despite these challenges, there is a notable lack of studies on the extent of multiple drug use and its determinants among patients with chronic kidney disease in Ethiopia. This study aims to assess the magnitude of multiple drug use and identify the determinants of vulnerability among patients with chronic kidney disease in Ethiopia.</p><p><strong>Method: </strong>A hospital-based cross-sectional study was conducted among patients with chronic kidney disease. Eligible participants were selected using a simple random sampling technique. Frequency and percentage calculations were performed for categorical variables, while means and standard deviations were used for continuous variables. The chi-square test and t-test were used to compare the proportions and means, respectively. Binary logistic regression was used to identify the determinants of multiple drug use, with statistical significance determined by a p-value of less than 0.05 and a 95% confidence interval.
