However, the diagnostic capacity of waist–hip ratio (WHR), conicity index (CI), and abdominal volume index (AVI) to predict visceral obesity in patients with type 2 diabetes remains unclear. This study was designed to evaluate the performance of WHR, CI, and AVI in predicting visceral fat among patients with type 2 diabetes in Ho municipality. Methods A hospital-based cross-sectional survey involved 221 patients with type 2 diabetes. A questionnaire was designed to collect data on demography and other relevant variables. Anthropometric measurements were obtained using standard methods. Visceral fat was measured using bioelectrical impedance analysis (BIA). The diagnostic performance of WHR, CI, and AVI in predicting visceral fat was evaluated based on receiver operating characteristics (ROC) curve analyses. Pearson correlation analysis was used to determine the relationship between adiposity indices and visceral fat. Results Among men, the optimal threshold for AVI, >15.56, demonstrated the highest sensitivity, 87.5% and specificity, 80.71% compared to CI and WHR while among women, the optimal cutoff value for AVI, >18.49, produced the highest sensitivity, 77.05% and specificity, 85.29%. Likewise, AVI showed a better discriminatory ability in the diagnosis of visceral fat (AUC: 0.89; p < 0.001) compared to CI (AUC: 0.68; p < 0.003), and WHR (AUC: 0.73; p < 0.001) in men and AUC: 0.89; p < 0.001 compared to CI (AUC: 0.62; p < 0.023), and WHR (AUC: 0.59; p < 0.066) in women. Similarly, the strongest positive correlation was observed between visceral fat and AVI after adjustment for age (male r = 0.787, p < 0.01; female r = 0.770, p < 0.01). Conclusion AVI appeared to have outperformed CI and WHR in the diagnosis of visceral fat. Therefore, it could be a better predictive tool for visceral obesity among patients with type 2 diabetes in low-resource settings.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45982070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the GCTs exhibit a typical epiphyseal location that shows a tendency for significant bone destruction and local recurrence. We aimed to assess the functional and oncological outcomes of GCT patients treated with bone grafting and cementation with or without gel foam. Materials and methods This prospective study included 40 patients presented at El Hadara University Hospital with GCT of bone around the knee from January 2017 to January 2022 treated by bone graft and cementation. Twenty cases were treated with gel foam (Group I) and 20 cases were treated without gel foam (Group II) through random allocation without selection. Recurrence was assessed as progressive lysis of 5 mm at the bone cement interface. Functional outcomes were assessed using the musculoskeletal tumor society score (MSTS) after a period of minimum 30 months. Results In Group I, 18 patients (90%) had excellent results (range 24 and 30) according to MSTS and two patients (10%) had good results (range 18 and 23), while in Group II, 16 patients (80%) had excellent results and four patients (20%) had good results. No patients were graded as having fair or poor results. Twenty patients (100%) had satisfactory results, and no patients (0%) had unsatisfactory results. The overall recurrence rate was about 15%. Conclusion Reconstruction of GCT of bone with sandwich technique offers good option as joint preserving surgery. Most of the patients get benefit in terms of better quality of life and good function regardless of age and gender. Subchondral bone grafting reduces the effect of heat on articular cartilage, but longer follow-up is required. There is no benefit of gel foam addition in terms of function or oncological outcome.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49090540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tuberculosis (TB) is one of those communicable diseases caused by the bacillus Mycobacterium tuberculosis which can be transmitted through droplet nuclei while coughing, sneezing, shouting, or singing. Infection with tuberculosis negatively affects the productive segment of the economy, resulting in a reduction in national productivity. The World Health Organization (WHO) recommended early case detection, accurate diagnosis, and standardized treatment as a means to prevent new infections. In Ethiopia, detecting TB cases early, diagnosing, and treating these cases as per the guideline has been practiced for years through the Directly Observed Treatment Short-course (DOTS) program which was started in 1997. Various researches on TB treatment outcomes and their predictors have been done in Ethiopia. However, almost all of the findings vary from each other even though the country has a standardized definition of the outcomes and data aggregation tools. Moreover, none of the findings and reports showed the magnitude of successful TB treatment outcomes in the study area. Objective: This research was intended to assess the prevalence of successful TB treatment outcomes among patients enrolled in a DOTS program in the east Gojjam zone, northwest Ethiopia. Result: Eighty six percent (86%) of all cases enrolled in the DOTS program were successfully treated in the East Gojjam zone, and sex, place of residence, educational status, smear result during entry to the DOTS program, and HIV test result were factors significantly affecting successful TB treatment outcomes in the study area. Conclusion and Recommendation: The magnitude of successful TB treatment outcome of this study is low compared to the national strategic plan. It is advisable to work on the identified factors to positively affect successful TB treatment outcomes in the study area.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49569914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods In a prospective cohort study, 1228 prediabetic patients were followed from 2003 until 2019 and longitudinal data on lipid indices (CHOL: cholesterol; HDL: high-density lipoprotein; LDL: low-density lipoprotein; TG: triglyceride) and fasting blood sugar (FBS) were recorded. The latent class growth model (LCGM) was used to estimate growth trajectories and to determine distinct subgroups (latent class) with a similar trajectory for lipid profile and FBS over time. The incidence of T2DM in extracted latent classes was compared. Results Finally, 946 people with complete data were included in statistical analysis. Two latent classes were identified based on the change in FBS including high-risk and low-risk classes (class size: 5.2% vs. 94.8%) with T2DM incidence rates 100% and 35.9%, respectively (P < 0.001). Two distinct subgroups were identified based on changes in lipid profile. Latent classes with abnormal TG, CHOL, HDL, and LDL included 18.8%, 21.8%, 38.8%, and 24% of study participants, respectively. The incidence rates of T2DM and remaining prediabetic in abnormal TG latent class were 57.2% and 30.8%, and in abnormal HDL latent class were 41.5% and 31.7% were significantly different from normal latent classes (P < 0.001). While in the extracted latent classes based on CHOL and LDL the incidence rates were not statistically significant differences (P > 0.05). Conclusions We identified two subgroups with high and low risk of future T2DM based on the changes in FBS and lipid profile by applying LCGM. The incidence of T2DM in extracted latent classes was significantly different. LCGM is a reliable approach for predicting the risk of T2DM incidence based on trajectories of risk factors.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48433297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study sought to determine the regular use of LLIN, factors associated with the usage and the effect of regular LLIN utilization on the development of malaria among under-five children. Methods This was a hospital-based cross-sectional observation study. We enrolled consecutive caregivers with their children aged 6 to 59 months who presented with fever in the absence of a localizing sign. A structured questionnaire was used to obtain information about the level of utilization of LLIN. Malaria parasitemia was detected using the P. falciparum rapid diagnostic test kit and/or microscopic examination of blood. Results A total of 303 children/caregivers pair was studied. The mother’s mean (SD) age was 37.17 (6.75) years, while the children was 24.36 (16.63) months. The majority (183; 60.4%) of the children were male. Parental awareness of LLIN was high (96.7%), LLIN ownership was 72.3%, however, only 119 (39.3%) were regular user of LLIN. Factors significantly associated with regular LLIN use were younger age, parental awareness, ownership of LLIN, source of acquisition of LLIN and permanently hanging the LLIN on sleeping space (p = 0.031, 0.010, 0.000, 0.006 and 0.000 respectively). Using binary logistic regression, the child’s age, source of LLIN and hanging the LLIN permanently on the bed remained statistically significant to the regular use of LLIN (p = 0.046, 0.035 and 0.000 respectively). The frequency of malaria was significantly higher among the children who did not use and those who uses LLIN irregularly (97.1% versus 32.9%, p = 0.000).

They often lead to early termination of the HD session affecting dialysis adequacy and patient overall health. The aim of the study was to create an artificial intelligence model and to assess its performance in the prediction of the occurrence of intradialytic clinical events. Methods We studied 6000 HD sessions performed for 215 ESRD patients, recording many predictors that included: patient, machine, and environmental factors. These data were collected within 24 weeks, including 12 weeks in the COVID 19 era and were used to develop and train an artificial neural network model (ANN) to predict the occurrence of intradialytic clinical events such as: hypotension, headache, hypertension, cramps, chest pain, nausea, vomiting, and dyspnea. Findings Our ANN model showed mean precision and recall of 96% and AUC of 99.3% in binary ANN to predict occurrence of an intradialytic complication (event or no event), while the accuracy of the categorical ANN in predicting the type of event was 82%. We found that heart rate changes, mean systolic pressure, ultrafiltration rate, dialyzate sodium, meal, urea reduction ratio, room humidity and dialysis session duration most strongly influence occurrence of an intradialytic complication.
