In low-income countries, renal dysfunction (RD) contributes to about 34% mortality in under-five children with severe acute malnutrition. This study aimed to determine the impacts of severe acute malnutrition on the kidney among the admitted under-five children. Methods: In this prospective longitudinal observational study, a total of 190 children aged 6 to 59 months were enrolled from Iringa and Dodoma tertiary hospitals. Socio-demographic, clinical and laboratory data were collected using a structured questionnaire. Estimated Glomerular Filtration Rate (eGFR) and urine albumin creatinine ratio (uACR) were used to determine RD. Data analysis was done using SPSS version 26 and statistical significance was assumed for factors with p-value Results: Out of 190 children with severe acute malnutrition, 36 (19%) had renal dysfunction. Factors associated with RD in malnourished children were the history of local herbs used within one week (AOR = 5.85, 95% CI [1.41, 24.319], p = 0.0152), Acute watery diarrhea with severe dehydration (AOR = 2.15, 95% CI [1.033, 4.711], p = 0.0166), and positive urine leukocytes (AOR = 19.91, 95% CI [4.09, 96.989], p = 0.0002). At three months of follow up, out of 36 children with RD, 20 (55.56%) attained full recovery, while 4 (11.11%) developed chronic kidney disease (CKD). Children with RD had prolonged hospital stays for more than 14 days with a mean 12.25 ± 5.00 days compared to those with no RD with a mean 6.29 ± 1.68 days (p Conclusion: Renal dysfunction is common among children with severe acute malnutrition. It is associated with prolonged hospital stays and increased mortality. Further studies which can determine the burden of RD in children with severe acute malnutrition as compared to those with no severe acute malnutrition are needed.展开更多

The large amount of excavation unloading of the soil below is also easy to induce the uneven settlement deformation of the existing structure above, affecting the safety of driving. Based on the shield tunnel project between Caoqiao Station and Lize Business District Station of Beijing Metro, this paper restores the construction site by constructing the finite element numerical model of the project area, calculates and analyzes the deformation and stress of the existing railway structure before and after the construction of the tunnel, and determines the safety impact of the new structure on the existing railway. The results show that the shield tunnel undercrossing construction will cause the “concave” settlement of the railway subgrade above. Under the condition of grouting reinforcement, the “concave” settlement curve is slower and the distribution range is wider. With the advancement of the construction step, the settlement deformation of the subgrade gradually increases. When the tunnel approaches and passes directly below the subgrade, the settlement deformation curve of the subgrade changes from slow to steep. After the tunnel passes away, the curve changes from steep to slow, and the deformation of the subgrade reaches the maximum after the tunnel is connected. Under the grouting condition, the maximum settlement deformation of the subgrade is 2.08 mm, which is about 45% of the settlement deformation of the subgrade under the non-grouting condition. The ground grouting reinforcement can effectively control the subgrade settlement, and the field monitoring verifies the rationality of the calculation results. After the tunnel passes underneath, the most unfavorable section of the existing railway frame bridge is located at the top plate of the structure, and the maximum crack width is 0.178 mm. After grouting reinforcement, the stress environment of the structure is improved, the crack width generated by the structure is smaller, the reinforcement area required for calculation is less, and the structural safety meets the requirements.展开更多

Methods: We conducted a descriptive and analytical retrospective study from September 2019 to August 2022 at the General Hospital Idrissa POUYE in Dakar, we reviewed all the medical records of patients from 15 to 60 years old who died while admitted in the cardiology department. Data collected were socioeconomic status, clinical history, type of cardiovascular disaese, length of hospitalization, circumstances and timing of death. The data were analyzed with R. Studio version 2022.12.0 + 353 and Excel 2019, with a P-value Results: The study included 73 patients, indicating a specific mortality rate of 8.8% and a proportional mortality of 39%. Predominantly male (sex ratio 1.2), the average age was 44. Key cardiovascular risk factors identified were sedentarism (76.7%), hypertension (28.8%), and smoking (21.9%). The leading cause for consultation was dyspnea (72.6%). Notable findings included a majority of patients presenting with general condition deterioration (90%) and cardiovascular collapse upon admission (23.3%). Physical exam revealed signs of heart failure in 63%. Echocardiography showed left ventricular ejection fraction impairment (81%) and pulmonary hypertension (78%). Immediate causes of death were primarily cardiogenic shock (45.2%) and septic shock (37%). The analytical study indicates that the data most closely associated with mortality were age, socio-economic level, ischemic heart disease (p = 0.034), rheumatic valvulopathies, pulmonary embolism (p = 0.034), hypertension (HTA) (p = 0.009), smoking (p = 0.011), diabetes (p = 0.011), dyslipidemias, prolonged bedrest (p = 0.001), morbid obesity (p = 0.001), and COVID-19 infection (p = 0.017). Conclusion: The prevalence of ischemic heart diseases, pulmonary embolisms, and valvulopathies in premature mortality statistics underscores the need for enhanced cardiovascular prevention efforts.展开更多

Children living in orphanages tend to be neglected and may be malnourished and they’re at risk of losing their full potential, with consequences to the child, nation and worldwide. Despite the nutritional concerns raised globally and in neighboring countries among these children, there exists an inadequate body of information about orphans’ nutritional status and feeding practices in Tanzania. This study aimed to assess the nutritional status, feeding practices and factors contributing to malnutrition among children aged 6 - 59 months in Arusha region orphanages, Tanzania. Study Objective: To assess the nutritional status, feeding practices and factors contributing to undernutrition among children aged 6 - 59 months in Arusha region orphanages, Tanzania. Methodology: This was an institution-based cross-sectional study conducted in selected orphanage Centre in the Arusha region. A representative sample size of 216 children aged 6 - 59 months in Arusha orphanages was selected to participate in the study. Multistaging sampling was used to select the study participants. Interviewer-administered questionnaires and anthropometric measurements were used during data collection. The data collected were entered, processed, and analyzed;continuous variables were summarized by use of mean and Standard deviation, while categorical variables were summarized by use of frequency, percentages and figures. Multivariable logistic regression was used to estimate the Odds Ratio with 95% CI and measure the strength of association between the outcomes with respect to selected independent variables. Variables with a p-value of less than 0.05 were considered statistically significant. Results: A total of 216 children from the orphanage Centre were involved in this study. Prevalence of Stunting, underweight and wasting among orphan children were 23.60%, 15.30% and 9.30%. The proportions of MDD and MMF were 89% and 99%. Children being on medication for any kind of illness during the survey (AOR: 7.9;95% CI: 1.95, 31.78), unmarried caregivers (AOR: 1.9;95% CI: 1.32, 10.86), fever 2 weeks before the survey (AOR: 2.9;95% CI: 1.09, 9.24) and orphanage Centre with more than 30 children (AOR: 1.8;95% CI: 1.08, 6.86) were found to be associated with undernutrition. Conclusion: In Arusha orphanages, the prevalence of stunting, underweight, and wasting among children exceeded WHO standards. Despite adequate feeding practices, the child’s illness, the number of children in the orphanage, and the marital status of caregivers were factors influencing the nutritional status of the orphans.展开更多
