Methodology: This was a retrospective cohort study. HIV-infected children on ART aged less than 15 years were divided into two groups Group 1 (G1) comprising children who started ART prior 2 years and Group (G2) those put on treatment thereafter. Main Measures: Percentage of children with growth retardation measured by Height for Age (H/A) and Weight for Age (W/A) Results: In total, we included 90 subjects. The median age was 10 years with a slight female predominance (51.2%). Most children were asymptomatic at the time of the study (96.6%), compliant with treatment (81%), 54.8% of children were on cotrimoxazole, 33% knew their status. At initiation, underweight was predominant in group 1 compared to group 2 (52% versus 29.5%;p = 0.015). Conversely, stunted growth predominated in G2 compared to G1 but without significant difference (38% versus 50%;p = 0.147). At the time of our study (median age of 10 years), catch-up height and weight predominated in G1 compared to G2;only a small proportion remained below −2SD (4% versus 18.2%;p = 0.015 and 9% versus 29.5%;p = 0.006 respectively for underweight and stunted growth). Conclusion and Global Health Implications: Growth retardation was common at ART initiation. Catch-up in height was more evident in the early treatment group. Initiation of ART before the age of 2 years rather influences children’s height than weight. The result of this study further emphasizes the need of early ART and closed clinical monitoring to better assess the impact of ART in areas with high rates of undernutrition.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

This intervention aimed to improve the knowledge, attitudes, and practices of mothers on food safety in the peri-urban areas of Bobo-Dioulasso in Burkina Faso. Methods: A total of 243 mothers of children under 5 years in the peri-urban of Bobo-Dioulasso were administered the FAO questionnaire for food safety knowledge, attitudes, and practices assessment during two cross-sectional surveys, before and after the intervention, in January and October 2017. The intervention included two components consisting of a theoretical phase (counselling and discussion) and cooking demonstrations implemented for ten months. To account for the before-and-after design of the study, the McNemar’s test was used to assess the effect of the intervention on food safety KAP of mothers of children under 5 years. Results: The mean age of mothers was 29 ± 6.2 years and 50.6% of them were between 20 and 29 years old. One for knowledge (cooking thoroughly with, p-value = 0.0001) and another for attitudes (perceived benefits of reheating leftovers before eating them, p-value = 0.0001), significantly increased after the intervention. In terms of food safety practices, all the indicators (cleaning of dirty surfaces, plates and utensils and storage of perishable foods) significantly increased (all p = 0.0001 Conclusion: This study provided some evidence of an effective nutrition education intervention for improving maternal KAP on food safety for their child’s feeding.展开更多

In order to improve performance, and the quality of care, and to identify common pathologies in the surgical department, we undertook a retrospective study on surgical activities from January 2009 to December 2010. At the end of this study, out of 474 men and 187 women (equal sex ratio 2.53);we were able to determine the frequency of surgical pathologies. Farmers, housewives and pupils/students were the most represented with 25.9% respectively;20% and 13.3%. The most frequently observed pathologies were wall hernia (44.8%), prostate adenoma (12%) and acute appendicitis (10.5%). The average length of hospitalization was 3.43 days. Infectious complications affected 25 patients (3.8% of cases) and a death rate of 0.45% (i.e. 3 patients). The average cost of care was 53,500 FCFA. Indeed, the reality of surgical practice in health centers was not the same because of the level of skills of practicing surgeons.展开更多

文摘In 1993,the World Bank released a global report on the efficacy of health promotion,introducing the disability-adjusted life years(DALY)as a novel indicator.The DALY,a composite metric incorporating temporal and qualitative data,is grounded in preferences regarding disability status.This review delineates the algorithm used to calculate the value of the proposed DALY synthetic indicator and elucidates key methodological challenges associated with its application.In contrast to the quality-adjusted life years approach,derived from multi-attribute utility theory,the DALY stands as an independent synthetic indicator that adopts the assumptions of the Time Trade Off utility technique to define Disability Weights.Claiming to rely on no mathematical or economic theory,DALY users appear to have exempted themselves from verifying whether this indicator meets the classical properties required of all indicators,notably content validity,reliability,specificity,and sensitivity.The DALY concept emerged primarily to facilitate comparisons of the health impacts of various diseases globally within the framework of the Global Burden of Disease initiative,leading to numerous publications in international literature.Despite widespread adoption,the DALY synthetic indicator has prompted significant methodological concerns since its inception,manifesting in inconsistent and non-reproducible results.Given the substantial diffusion of the DALY indicator and its critical role in health impact assessments,a reassessment is warranted.This reconsideration is imperative for enhancing the robustness and reliability of public health decisionmaking processes.

文摘Objective: To study the effects of starting antiretroviral treatment (ART) prior the age of two years on the growth (height and weight) of HIV-infected children. Methodology: This was a retrospective cohort study. HIV-infected children on ART aged less than 15 years were divided into two groups Group 1 (G1) comprising children who started ART prior 2 years and Group (G2) those put on treatment thereafter. Main Measures: Percentage of children with growth retardation measured by Height for Age (H/A) and Weight for Age (W/A) Results: In total, we included 90 subjects. The median age was 10 years with a slight female predominance (51.2%). Most children were asymptomatic at the time of the study (96.6%), compliant with treatment (81%), 54.8% of children were on cotrimoxazole, 33% knew their status. At initiation, underweight was predominant in group 1 compared to group 2 (52% versus 29.5%;p = 0.015). Conversely, stunted growth predominated in G2 compared to G1 but without significant difference (38% versus 50%;p = 0.147). At the time of our study (median age of 10 years), catch-up height and weight predominated in G1 compared to G2;only a small proportion remained below −2SD (4% versus 18.2%;p = 0.015 and 9% versus 29.5%;p = 0.006 respectively for underweight and stunted growth). Conclusion and Global Health Implications: Growth retardation was common at ART initiation. Catch-up in height was more evident in the early treatment group. Initiation of ART before the age of 2 years rather influences children’s height than weight. The result of this study further emphasizes the need of early ART and closed clinical monitoring to better assess the impact of ART in areas with high rates of undernutrition.

文摘This study investigated the effects of planting duration(1,5,10 and 15 years)on soil properties,bacterial community diversity,and function in the rhizosphere of Zanthoxylum bungeanum.We employed Illumina highthroughput sequencing and PICRUSt2 functional prediction to analyze the structure and functional potential of rhizosphere soil bacterial communities.The Mantel test and redundancy analysis were used to identify physicochemical factors influencing bacterial community structure and function.The results indicated significant differences in rhizosphere soil physicochemical properties across planting years:the content of organic matter,alkaline hydrolyzable nitrogen in the soil,as well as the activity of invertase,urease,and alkaline phosphatase initially increased and then decreased,while available potassium,Olsen-phosphorus content,and peroxidase activity continued to increase.However,bacterial alpha diversity(Chao1 and Shannon indices)and the number of amplicon sequence variants increased continuously with planting duration.Principal coordinate analysis and Adonis tests revealed that the planting year significantly influenced the bacterial community structure(p<0.05).The phyla Proteobacteria,Actinobacteria,Acidobacteriota and Chloroflexi collectively constituted 56.7%to 71.2%of the relative abundance,representing the dominant taxa.PICRUSt2 predictions indicated key functional categories(cellular processes,metabolism,genetic information processing,and environmental information processing)each exceeding 10%relative abundance.BugBase analysis revealed a progressive increase in aerobic and oxidative stress-tolerant bacteria and a decrease in anaerobic and potentially pathogenic bacteria.Differential indicator species analysis identified Firmicutes,Planctomycetes,Methylomirabilota and Actinobacteriota as key discriminators for the 1-,5-,10-and 15-year stages,respectively.Organic matter,alkaline phosphatase,soil pH,and available phosphorus were the primary physicochemical drivers of bacterial communities.Notably,soil organic matter significantly influenced both the community structure(p<0.05)and predictedmetabolic functions(p<0.05).In conclusion,prolonged planting duration significantly enhanced rhizosphere microbial diversity and functional gene abundance in Z.bungeanumwhile driving the structural succession of bacterial communities dominated by Proteobacteria,Actinobacteria,Acidobacteriota,and Chloroflexi.This ecological shift,characterized by increased aerobic/oxidative-stress taxa and decreased anaerobic/pathogenic bacteria,was primarily regulated by soil organic matter,a key driver shaping both community structure and metabolic functions,ultimately improving soil microecological health.

文摘BACKGROUND Physical inactivity is a significant yet underappreciated risk factor for cardiovascular disease(CVD),particularly among older adults.The aim of this study was to analyze the global burden of CVD attributable to physical inactivity in individuals aged 70 years and older from 1990 to 2021 using the Global Burden of Disease data.METHODS We assessed trends in disability-adjusted life years(DALYs)and deaths,decomposed changes into population growth,aging,and epidemiological factors,and examined health inequalities across sociodemographic index(SDI)regions.RESULTS From 1990 to 2021,a substantial rise in DALYs was observed,especially in low and middle SDI regions,with a 120.06% increase in the low SDI region,but a 23.10% decline in the high SDI region.Decomposition analysis identified population aging and growth as primary drivers for the burden,contributing 66.39% and 83.56% to the increase in middle and low SDI regions,respectively.By contrast,epidemiological improvements alleviated burden in the high SDI region(54.91%).Gender disparities persisted,with women experiencing a higher burden.Inequality analysis indicated a shift in CVD burden towards the low SDI region,with declining concentration indices for DALYs(-0.03 to-0.13)and deaths(-0.07 to-0.15).The Bayesian age-period-cohort projections suggest continued increases in DALYs and deaths through 2050,with women disproportionately affected.CONCLUSIONS These findings highlight the urgent need for targeted interventions promoting physical activity,improving healthcare access,and implementing region-specific prevention strategies.

文摘This study analyzed case and prescription data of children aged 12 to 18 years diagnosed with influenza A from the outpatient and emergency departments at the Women and Children’s Hospital of Ningbo University during the influenza epidemic period between February and April 2023.Patients were categorized into two groups based on their medication:the Baloxavir Marboxil group(196 cases)and the Oseltamivir group(126 cases).SPSS Statistics 24.0 software was utilized to compare variables between the two groups,including age,sex,weight,first visit department,number of visits,average prescription cost per patient,drug varieties used,hospitalization rate,and the combined medication usage,to evaluate the relative advantages and disadvantages of the two treatments.The results indicated that the number of visits in the Baloxavir Marboxil group was significantly lower than in the Oseltamivir group,whereas the average prescription cost per patient was higher(P<0.05).There were no significant differences between the two groups regarding age,sex,weight,first visit department,number of drug types used,hospitalization rate,or combined medication usage(P>0.05).When comparing the use of single-class combined drugs,only the quantity of antiviral drugs differed significantly(P<0.05).The Oseltamivir group required more adjuvant treatment with both Chinese and Western antiviral medications.The distribution of the number of combined drug types was concentrated around three and two types in both groups(Baloxavir Marboxil group:41.34%and 39.66%;Oseltamivir group:44.54%and 36.97%).This study highlighted that the new drug,Baloxavir Marboxil,offered certain therapeutic benefits over Oseltamivir in treating influenza among children aged 12 to 18 years,including advantages in single-dose administration,oral compliance,and specific treatment outcomes.The higher unit cost associated with Baloxavir Marboxil might be a factor for further consideration.These findings provided a new reference point for the clinical selection of anti-influenza medications.

文摘The existence of an intensifying shift in the East Asian summer monsoon(EASM)since~2000 years ago that differs from the decreasing trend of Northern Hemisphere summer insolation remains controversial.Therefore,we compared and synthesized stalagmiteδ^(18)O records from eastern China to clarify the EASM trend during this period.A total of 30 caveδ^(18)O records that did not consistently indicate a depleted trend during 2-0 ka.Rather,they included increasing(14 caves),decreasing(8 caves),and non-significant(8 caves)trends.The spatially interpolated trends of caveδ^(18)O suggested spatial differences among three subregions:North China(NC),decreasing trend(5 caves);Central-East China/Yangtze River Valley(CEC),increasing trend(17 caves);South China(SC),decreasing trend(8 caves).The caveδ^(18)O evidence supports spatial differences in precipitation in eastern China that have been substantially demonstrated by observations and model simulations.The decreasingδ^(18)O anomaly from NC and SC was associated with the decreasing sea surface temperature over Pacific Decadal Oscillation region and increasing South Oscillation Index.The increasing CECδ^(18)O anomaly was linked to southward Intertropical Convergence Zone shift and decreasing solar irradiance.Consequently,EASM circulation is jointly forced by external and internal factors at various timescales.

文摘The historical movements of relative sea level(RSL)reflect the geomorphological dynamics around coastal regions in the past,and reconstructing the RSL curve contributes to the prediction of future RSL movements.On the basis of the sediment sequence and optical stimulated luminescence(OSL)dating data of three boreholes in the Yellow River Delta(YRD),the positions of paleo-coastlines and the movements of RSL in the last 2000 years were reconstructed.The main results are as follows:1)the YRD coast transformed from a tide-dominated silty coast to a wave-dominated sandy coast and back to a tide-dominated silty coast in the last 2000 years.2)The sand layers consisting of shell fragments indicated the locations of the coastline in 1855 AD,893 AD,and 40 BC,and their top elevations were close to the mean high water level in the corresponding years.3)The mean sea level elevation in 79 BC,1019 AD,and 1800 AD relative to the modern sea level was -4.52,-4.52,and-2.92 m,respectively.4)The RSL was almost stagnant during 79 BC-1019 AD,rose slowly during 1019-1800 AD due to the reverse change of global climate from the Little Ice Age to the Medieval Warm Period,and rose significantly after 1800 AD due to the warm period.5)The movement of RSL controlled the surface slope of YRD,which was a slope of approximately 0.022‰ at 893 AD,an inverted slope of 0.144‰ at 1855 AD,and a slope of 0.075‰ recently.These findings indicate that the modern YRD is far from being abandoned in the future,providing a historical geomorphological basis for the management of the Yellow River Estuary.

文摘Objective:Children below 14 years of age are highly vulnerable to dengue infection and are at a greater risk of developing severe dengue illness.This study aimed to investigate the trends in the burden of dengue fever among children below 14 years of age in China from 1990 to 2021 and to project the disease burden from 2022 to 2035.Methods:Based on the datasets derived from the Global Burden of Disease Study 2021,the following data were collected from dengue-affected children aged ≤14 years in China from 1990 to 2021:number and rate of incident dengue cases,number of prevalent dengue cases,number of deaths due to dengue,and disability-adjusted life years(DALYs) lost due to dengue.The trends in disease burden were examined based on average annual percent change(AAPC) and annual percent change,and the burdens were proj ected from 2022 to 2035 by using a Bayesian age-period-cohort model.Results:The incidence and prevalence of dengue fever were increased in children aged ≤ 14 years in China from1990 to 2021(AAPC=5.42 % and 5.44 %,respectively,P <0.001),while the mortality and DALYs rates were reduced(AAPC=-8.21 % and-7.55 %,respectively,P <0.001).The burden was comparable between genders,with numerically lower incidence and prevalence in boys than in girls.The lowest incidence and prevalence and the highest mortality and DALYs rates were observed in children aged <5 years.The incidence and prevalence rates were projected to increase from 2022 to 2035;in contrast,the mortality and DALYs rates were projected to decrease during this period.Conclusions:Although the mortality and DALYs rates of dengue fever decreased significantly in children aged0-14 years in China from 1990 to 2021,the incidence and prevalence increased remarkably.Enhanced surveillance and ample health education programs and preventive interventions are recommended for targeting this high-risk population.
文摘Objectives:The increasing number of elderly patients with severe aortic valve stenosis undergoing transcatheter aortic valve replacement(TAVR)has prompted concerns regarding their clinical outcomes compared with the younger population.This study evaluated the outcomes of TAVR on the basis of age group(<80 or≥80 years)amongVietnamese patients with severe aortic valve stenosis at intermediate surgical risk.Methods:From March 2017 to December 2022,21 patients≥80 years of age and 69 patients<80 years of age under-went TAVI at a single center.Clinical characteristics,procedures,and outcomes at 30 days and 1 year were compared with the Valve Academic Research Consortium(VARC-2)criteria.Results:Patients≥80 years of age had a higher prevalence of comorbidities but no significant differences in other clinical characteristics and procedures.No statistically significant differences were observed in procedural mortality(4.8%vs.0.0%,P=0.233),30-day mortality(5.0%vs.1.5%,P=0.405),and 1-year mortality(11.8%vs.3.7%,P=0.241)between age groups.Major endpoints at specified time points also showed no significant differences.Conclusions:TAVR in patients with aortic stenosis at intermediate surgical risk has similar clinical outcomes at 30 days and 1 year,according to VARC-2 criteria,with no statistically significant age-associated differences(≥80 vs.<80 years).However,further studies with larger patient populations are needed to better understand the effects of age on TAVI outcomes in patients with similar characteristics.
文摘Objective This study aimed to determine the current epidemiological status of PLWHA aged≥50 years in China from 2018 to 2021.It also aimed to recommend targeted interventions for the prevention and treatment of HIV/AIDS in elderly patients.Methods Data on newly reported cases of PLWHA,aged≥50 years in China from 2018 to 2021,were collected using the CRIMS.Trend tests and spatial analyses were also conducted.Results Between 2018 and 2021,237,724 HIV/AIDS cases were reported among patients aged≥50 years in China.The main transmission route was heterosexual transmission(91.24%).Commercial heterosexual transmission(CHC)was the primary mode of transmission among males,while non-marital non-CHC([NMNCHC];60.59%)was the prevalent route in women.The proportion of patients with CHC decreased over time(Z=67.716,P<0.01),while that of patients with NMNCHC increased(Z=153.05,P<0.01).The sex ratio varied among the different modes of infection,and it peaked at 17.65 for CHC.The spatial analysis indicated spatial clustering,and the high-high clustering areas were mainly distributed in the southwestern and central-southern provinces.Conclusion In China,PLWHA,aged≥50 years,were predominantly infected through heterosexual transmission.The primary modes of infection were CHC and NMNCHC.There were variations in the sex ratio among different age groups,infected through various sexual behaviors.HIV/AIDS cases exhibited spatial clustering.Based on these results,the expansion of HIV testing,treatment,and integrated behavioral interventions in high-risk populations is recommended to enhance disease detection in key regions.

文摘BACKGROUND The incidence and mortality rate of colorectal cancer progressively increase with age and become particularly prominent after the age of 50 years.Therefore,the population that is≥50 years in age requires long-term and regular colonoscopies.Uncomfortable bowel preparation is the main reason preventing patients from undergoing regular colonoscopies.The standard bowel preparation regimen of 4-L polyethylene glycol(PEG)is effective but poorly tolerated.AIM To investigate an effective and comfortable bowel preparation regimen for hospitalized patients≥50 years in age.METHODS Patients were randomly assigned to group 1(2-L PEG+30-mL lactulose+a lowresidue diet)or group 2(4-L PEG).Adequate bowel preparation was defined as a Boston bowel preparation scale(BBPS)score of≥6,with a score of≥2 for each segment.Non-inferiority was prespecified with a margin of 10%.Additionally,the degree of comfort was assessed based on the comfort questionnaire.RESULTS The proportion of patients with a BBPS score of≥6 in group 1 was not significantly different from that in group 2,as demonstrated by intention-to-treat(91.2%vs 91.0%,P=0.953)and per-protocol(91.8%vs 91.0%,P=0.802)analyses.Furthermore,in patients≥75 years in age,the proportion of BBPS scores of≥6 in group 1 was not significantly different from that in group 2(90.9%vs 97.0%,P=0.716).Group 1 had higher comfort scores(8.85±1.162 vs 7.59±1.735,P<0.001),longer sleep duration(6.86±1.204 h vs 5.80±1.730 h,P<0.001),and fewer awakenings(1.42±1.183 vs 2.04±1.835,P=0.026)than group 2.CONCLUSION For hospitalized patients≥50 years in age,the bowel preparation regimen comprising 2-L PEG+30-mL lactulose+a low-residue diet produced a cleanse that was as effective as the 4-L PEG regimen and even provided better comfort.
文摘Background: Our study aimed to examine cardiovascular mortality within the working-age population, exploring epidemiological, clinical, and paraclinical features, complications, and identifying etiological factors linked to mortality. 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.
文摘Background: This study assessed the effect of a nutrition education intervention. This intervention aimed to improve the knowledge, attitudes, and practices of mothers on food safety in the peri-urban areas of Bobo-Dioulasso in Burkina Faso. Methods: A total of 243 mothers of children under 5 years in the peri-urban of Bobo-Dioulasso were administered the FAO questionnaire for food safety knowledge, attitudes, and practices assessment during two cross-sectional surveys, before and after the intervention, in January and October 2017. The intervention included two components consisting of a theoretical phase (counselling and discussion) and cooking demonstrations implemented for ten months. To account for the before-and-after design of the study, the McNemar’s test was used to assess the effect of the intervention on food safety KAP of mothers of children under 5 years. Results: The mean age of mothers was 29 ± 6.2 years and 50.6% of them were between 20 and 29 years old. One for knowledge (cooking thoroughly with, p-value = 0.0001) and another for attitudes (perceived benefits of reheating leftovers before eating them, p-value = 0.0001), significantly increased after the intervention. In terms of food safety practices, all the indicators (cleaning of dirty surfaces, plates and utensils and storage of perishable foods) significantly increased (all p = 0.0001 Conclusion: This study provided some evidence of an effective nutrition education intervention for improving maternal KAP on food safety for their child’s feeding.
文摘The objectives of this work were to evaluate the surgical activities carried out in the general surgery department of the Reference Health Center of Commune I of Bamako, to describe the sociodemographic characteristics of the operated patients, to determine the main pathologies encountered and to evaluate qualitatively the result of the treatment. In order to improve performance, and the quality of care, and to identify common pathologies in the surgical department, we undertook a retrospective study on surgical activities from January 2009 to December 2010. At the end of this study, out of 474 men and 187 women (equal sex ratio 2.53);we were able to determine the frequency of surgical pathologies. Farmers, housewives and pupils/students were the most represented with 25.9% respectively;20% and 13.3%. The most frequently observed pathologies were wall hernia (44.8%), prostate adenoma (12%) and acute appendicitis (10.5%). The average length of hospitalization was 3.43 days. Infectious complications affected 25 patients (3.8% of cases) and a death rate of 0.45% (i.e. 3 patients). The average cost of care was 53,500 FCFA. Indeed, the reality of surgical practice in health centers was not the same because of the level of skills of practicing surgeons.

文摘The Ground Cover Rice Production System(GCRPS)has considerable potential for securing rice production in hilly areas.However,its impact on yields and nitrogen(N)fates remains uncertain under varying rainfall conditions.A two-year field experiment(2021–2022)was conducted in Ziyang,Sichuan Province,located in the hilly areas of Southwest China.The experiment included two cultivation methods:conventional flooding paddy(Paddy,W1)and GCRPS(W2).These methods were combined with three N management practices:N1(no-N fertilizer),N2(135 kg/hm^(2)urea as a base fertilizer in both W1 and W2),and N3(135 kg/hm^(2)urea with split application for W1 and 67.5 kg/hm^(2)urea and chicken manure separately for W2).The WHCNS(Soil Water Heat Carbon Nitrogen Simulator)model was calibrated and validated to simulate ponding water depth,soil water storage,soil mineral N content,leaf area index,aboveground dry matter,crop N uptake,and rice yield.Subsequently,this model was used to simulate the responses of rice yield and N fates to GCRPS under different types of precipitation years using meteorological data from 1980 to 2018.The results indicated that the WHCNS model performed well in simulating crop growth and N fates for both Paddy and GCRPS.Compared with Paddy,GCRPS reduced N leaching(35.1%–54.9%),ammonia volatilization(0.7%–13.6%),N runoff(71.1%–83.5%),denitrification(3.8%–6.7%),and total N loss(33.8%–56.9%)for all precipitation year types.However,GCRPS reduced crop N uptake and yield during wet years,while increasing crop N uptake and yield during dry and normal years.Fertilizer application reduced the stability and sustainability of rice yield in wet years,but increased the stability and sustainability of rice yield in dry and normal years.In conclusion,GCRPS is more suitable for normal and dry years in the study region,leading to increased rice yield and reduced N loss.
