We aim to determine the frequency of uncontrolled hypertension in hypertensive patients followed up as an outpatient at the campus university hospital of Lome (Togo) and to search for the associated factors. Methodology: The study was cross-sectional, descriptive and analytical, carried out from February (2022) to August 2022 in 260 hypertensive patients aged 22 years old, followed up (on an) as an outpatient for at least 3 months at the Lome University Hospital campus. A univariate then multivariate analysis were conducted in order to highlight the most common factors significantly linked to uncontrolled. Results: The mean age of hypertensives was 56.4 ± 12.7 years, the sex ratio (M/F) was 0.59. Prevalence of uncontrolled blood pressure was 42%. Associated Factors to poor blood pressure control in our study were age > 60 years (OR = 1.6 CI [1.17 - 2.50]), low socio-economic level (OR = 2.2 CI [1.96 - 4.33]), high cardiovascular risk level (OR = 3.1 CI [2.18 - 4.52]), non-adherence to regular blood pressure monitoring (OR = 3.3 CI [2.21 - 5.55]), low compliance to treatment (OR = 4.1 CI [2.33 - 6.76]) and a chronic renal failure (OR = 2.1 CI [1.21 - 3.10]). Conclusion: Nearly half of the hypertensives in our study had poorly controlled blood pressure by antihypertensive treatment medication. The factors of this poor control were age > 60 years, low socio-economic level, high or very high level of cardiovascular risk, low compliance to treatment, and renal failure.展开更多

It accounts for 6 to 8% of incident cases of end-stage chronic renal disease (ESRD) in developed countries. The aim of this study is to describe the predictive factors for the development of end-stage chronic kidney disease (CKD) in the course of this disease. Material and Methods: This is a retrospective, descriptive, and analytical study including 300 cases of ADPKD collected at the Nephrology Department of Ibn-Sina Hospital in Rabat over a period of 30 years (1993 to 2023). Included in the study are all patients with ADPKD meeting the ultrasound diagnostic criteria. The analysis focused on demographic, clinical, paraclinical, evolutionary data, as well as prognostic factors associated with renal function deterioration. Results: The mean age of patients at diagnosis is 51.53 +/− 17 years [16 - 93] with a male predominance. The median serum creatinine at diagnosis is 15.5 mg/l [10 - 34]. 21% of patients had ESRD (eGFR 300 mg/24h (21%). The most common cystic complication is hemorrhage (12.3%). 21.3% of patients had hepatorenal polycystic disease. In adjusted analysis, the predictive risk factors for the occurrence of ESRD were smoking (p = 0.019), anemia (p Conclusion: ADPKD can progress insidiously to ESRD. Identification and early treatment of predictive factors for poor renal prognosis could contribute to a better outcome for this disease.展开更多

There is a lack of evidence in literature though for what happens to such kidneys, in the long run, particularly those which are poorly functioning.AIM To assess the long-term outcomes of ureteric reimplantation in poorly functioning kidneys in children with unilateral primary VUR.METHODS Children with unilateral primary VUR and a relative renal function of less than 35% who underwent open or laparoscopic ureteric reimplantation between January 2005 and January 2017 were included in the study. Patients who had a follow up of less than five years were excluded. Preoperative evaluation consisted of a voiding cystourethrogram and Dimercaptosuccinic acid(DMSA) scan. In the follow-up period, patients underwent a diuretic scan at 6 weeks and 6 months.Follow up ultrasound was done for change in grade of hydronephrosis and retrovesical ureteric diameter. Subsequent follow up was done at 6 monthly intervals with evaluation for proteinuria and hypertension and any recurrent urinary tract infection(UTI). For assessment of cortical function, DMSA was repeated annually for 5 years after surgery. A paired-samples t-test was used to test the mean difference of DMSA between pre-post observations.RESULTS During this period, 36 children underwent ureteric reimplantation for unilateral primary VUR. After excluding those with insufficient follow-up, 31 were included in the analysis. Most of the patients were males(n = 26/31, 83.8%). Patient’s age(mean ± SD, range) was 5.21 ± 3.71, 1-18 years. The grades of VUR were grade Ⅱ(1patient), grade Ⅲ(8 patients), grade Ⅳ(10 patients), and grade Ⅴ(12 patients). The pre and postoperative DMSA was 24.064 ± 12.02 and 24.06 ± 10.93, which was almost the same(statistically equal, paired-samples t-test: P = 0.873). The median(range) follow-up duration was 82(60-120)mo. One patient had persistent reflux after surgery(preoperative: grade Ⅳ, postoperative: grade Ⅲ), and the very same patient developed recurrent UTI. The difference in the preoperative and postoperative DRF was less than 10% in 29 patients. In one patient, the DRF decreased by 17%(22% to 05%) while in another patient, the DRF increased by 12%(25% to 37%) after surgery. None of the patients had an increase in scarring after surgery. 15% of patients were hypertensive before surgery and all of them continued to be hypertensive after surgery while none developed hypertension after surgery. None of the patients had significant proteinuria(> 150 mg/d) during the follow-up period.CONCLUSION Children with unilateral primary VUR and poorly functioning kidney maintain the renal function over the long term in most cases. Hypertension and proteinuria do not progress over time in these patients.展开更多

文摘The present study aimed to evaluate the hygiene practices and the quality of meat sold in butcheries in the city of Nampula,Mozambique.Of the twelve butcheries in the city,only seven participated in the study,which was divided into four categories:hygienic conditions of buildings and facilities,equipment,furniture and utensils,good handling practices for handlers,and microbiological quality of meat products.Results showed that most of the butcheries(71%)had poor hygiene conditions,such as walls with cracks and holes and lack of washbasins in the production area.In addition,the majority(71%)of butcheries used a reusable dirty cloth to clean equipment and utensils,and only 43%had a cold room or refrigerated chamber for meat conservation.Regarding personal hygiene,100%of the handlers washed and changed their clothes daily,but 71%did not properly wash their hands before handling food.Microbiological analysis revealed that 86%of the cutting tables swabs and 43%of the hand blades had E.coli counts above 4 Log,and the presence of Salmonella was observed in 71%of meat samples.Overall,the study highlights the need for improvement in hygiene practices and the quality of meat sold in butcheries in Nampula.
文摘目的分析介入取栓治疗急性缺血性脑卒中(acute ischemic stroke,AIS)预后不良的临床特征及风险因素。方法回顾性分析172例AIS病例资料,均行介入取栓治疗。术后随访3个月,预后情况根据改良Rankin量表(modified Rankin scale,mRS)分为预后不良组(mRS 3~5分)69例和预后良好组(mRS 0~2分)103例。通过单因素及多因素Logistic分析,研究AIS患者介入取栓治疗预后不良的临床特征及风险因素。结果术后随访3个月,预后不良组69例,发生率40.12%。与预后良好组比较,预后不良组年龄>60岁比例更高,发病至入院时间、术前美国国立卫生院卒中量表(national institute of health stroke scale,NIHSS)评分、术前Alberta急性脑卒中分级早期CT(Alberta stroke program early CT,ASPECT)评分、取栓次数、入院时血糖水平、入院时同型半胱氨酸(Hcy)水平更高(均P<0.05)。多因素Logistic分析结果显示:AIS介入取栓治疗预后不良的危险因素包括发病至入院时间延长、术前NIHSS评分、术前ASPECT评分、入院时血糖水平升高(OR分别为1.813、1.990、1.782、2.335,均P<0.05)。结论AIS患者介入取栓治疗预后不良的危险因素包括发病至入院时间延长,NIHSS评分、ASPECT评分、血糖水平升高,可据此筛选具备低风险因素的患者进行干预,针对性制定预防措施,进而改善患者预后。
