The aim was to study knowledge of cardiovascular risk factors among residents of Dakar. Patients and Methods: This was a descriptive cross-sectional study. Our investigations were recruited over a six-month period (October 17, 2021 to March 21, 2022). Results: Two hundred and twenty-six (226) patients were enrolled. The mean age was 45.9 years. The under-40 age group was the most represented with 37.2%. There were 129 men (57.1%), giving a male/female sex ratio of 1.33. The highest level was represented by 159 people (70.4%). Those who responded (heart disease) were in the majority (38.1%). Hypertension was the most common CVD for 101 people (44.7%). One hundred and ninety (190) people (84%) knew the risk factors for CVD. Good knowledge of risk factors concerned 103 people (54.2%). Obesity was the best-known risk factor in 156 cases (69%). The media was the most important source of information for 121 people (53.5%). Hypertensives were the most represented with 8.4%. One hundred and thirty (130) people (57.5%) had previously paid attention to these FDRCVs. Awareness campaigns were the most effective means of communication for 170 cases (75.2%). Sixteen (16) people (35.6%) were taking antihypertensive medication. Walking was the most popular physical activity for 102 people (45%). People with a balanced diet were in the majority, with 174 respondents (77.0%). Conclusion: NCDs are a major cause of morbidity and mortality. It is essential to develop and implement a prevention and management program.展开更多

Although street foods can provide nutritious and affordable ready-to-eat meals for city dwellers, their health risks can outweigh the benefits. A cross-sectional study was conducted in the Bamako district, focusing on street food vendors near schools, universities, extensive markets, administrative centers, and major roads. We aimed to sample fifty (50) sellers per municipality, making 300 sellers for the Bamako district. We developed a survey sheet to collect data, and six teams rotated between the municipalities each month. Before starting the collection, the teams were provided administrative papers approved by the municipal authority. The survey revealed three types of sales sites: fixed (65%), semi-fixed (30%), and mobile (4.40%). The proportion of sellers was 26.8%, 23.2%, 19.7%, and 4.2% in municipalities III, IV, and I. In municipalities I, II, III, IV, and VI, respectively, 92%, 95.70%, 93%, 87.2%, and 100% of the sellers were female. The age distribution of sellers was 65.63%, 46.81%, 40.82%, 38.30%, 36.17%, 36%, and 32% in the 25-34 and 35 - 44 age groups. Illiteracy rates were 59.20%, 61.70%, 55.30%, 75%, and 56% in municipalities I, II, III, IV, and VI, respectively. The study identified two categories of sellers: 48.3% in type 1 and 51.7% in type 2. The first category comprised 154 sellers, and the second 165 sellers. The survey found that 66.00%, 56.00%, 48.90%, 44.90%, 38.30%, and 34.40% of municipal V, VI, III, I, II, and IV sales sites were open-air. In municipality I, 63.30% of the sites were under hangars, while in municipalities II and IV, the corresponding percentages were 51.10% and 59.40%, respectively. Moreover, 46.00%, 31.90%, 31.30%, 30.60%, and 27.70% of the sites in municipalities VI, II, IV, I, and III were located next to gutters. In conclusion, this study identified several factors that could compromise the quality of street foods sold in the six municipalities of Bamako.展开更多

This complex and multifactorial disease poses a significant challenge to dairy camel farming, particularly in Somalia. The studys objective was to determine the prevalence of mastitis and the risk factors associated with it among lactating camels on dairy farms in Benadir, Somalia. To achieve this, a cross-sectional study was conducted from May to September 2022 in the Benadir region of Somalia. A total of 96 lactating camels underwent examination using the California Mastitis Test (CMT) to identify clinical and subclinical mastitis cases. Additionally, a questionnaire survey was conducted among 20 farm employees/owners to gather information on hygiene practices, parity, lactation stage, tick infestation, and the presence of udder/teat lesions. Data regarding parity and lactation stage were obtained through owner interviews. The data collected on specifically designed forms were recorded and entered into a Microsoft Excel spreadsheet for analysis using SPSS version 20 statistical software, ensuring a comprehensive and reliable analysis of the data. The studys findings revealed a significant prevalence of camel mastitis, with 34.4% (33/96) of lactating camels affected and clinical and subclinical cases constituting 5.2% and 29.2%, respectively. Quarter-level prevalence was 46.3%, with clinical and subclinical mastitis at 4.7% and 41.6%, respectively. The study also identified significant associations (P < 0.05) among risk factors such as stage of lactation, parity, and age, indicating a higher susceptibility to mastitis in older camels during early lactation compared to those in late lactation and younger camels. These findings underscore the crucial role of inadequate hygienic conditions on camel farms and udder tick infestations in driving the elevated prevalence of mastitis, highlighting the need for improved management practices in dairy farming in Benadir, Somalia. Effective interventions, including improved management practices and extension services, are essential to reduce the burden of mastitis in dairy camels.展开更多

Garoua city is the headquarters of the North Region of Cameroon, where the HBV prevalence is among the highest of the country. The aim of this study was to determine the prevalence of HBsAg carriage and associated factors among persons incarcerated in the Garoua Central Prison. Methods: It was a cross-sectional study conducted from July 1 to July 31, 2023 at the Garoua Central prison. We included all prisoners willing to participate in the study and who gave their verbal consent. We collected data using a pre-established data entry form and we used rapid test for blood screening for HBV surface antigen (HBs Ag) with ELISA confirmation. Data were analyzed using the R<sup>®</sup> software for Windows. After the univariate analysis, we selected associated variables to HBV infection with p-value p-value was set at 5%. Results: We included 1389 prisoners out of which 97.6% were male. The median age (IQR) of the study population was 28 (23 - 35) years. The median (IQR) duration of incarceration was 12 (6 - 26) months and the mean (±sd) number of incarcerations was 1.24 (±0.6). HBV prevalence was estimated at 14.8% (95% CI: 13.0 - 16.7). Upon uni- and multivariate analysis, no risk factor was significantly associated with viral hepatitis B infection in our study population. Conclusion: The prevalence of Hepatitis B was high in the Garoua Central Prison, but there were no additional risk factors for HBV infection. There is a need to include the Garoua Central Prison and by the way other prisons in the country in the chronic viral hepatitis care program.展开更多

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

However, protective factors associated with depression among pregnant Japanese women during the pandemic have not been reported. Purpose: The present study investigated the risk and protective factors associated with depression and anxiety among pregnant women during the COVID-19 pandemic. Methods: An online questionnaire was administered to 157 pregnant women between October 2022 and May 2023 at two general hospitals in Japan. The Japanese versions of the Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 (GAD-7) were used to assess symptoms of depression and anxiety. The χ<sup>2</sup> test or Fisher’s exact test and multivariate logistic regression model were used to examine factors associated with depression and anxiety among pregnant women. Results: Overall, 47.1% and 35.7% of the pregnant women reported depressive and anxiety symptoms, respectively. A “history of mental illness” was a risk factor for depression and anxiety among pregnant women during the COVID-19 pandemic. Additionally, unmarried status was a risk factor for anxiety among pregnant women, whereas outdoor and indoor exercises were protective factors against depression and anxiety, respectively. Conclusions: Exercise may have protected pregnant women from depression and anxiety during the COVID-19 pandemic. Encouraging exercise may help maintain the mental health of pregnant women who do not have exercise restrictions.展开更多

The general objective was to determine the epidemiological aspects of obesity, overweight and associated risk factors in a semi-urban environment. Patients and Methods: This was a cross-sectional, descriptive study conducted on November 28 and 29, 2023 in Sébikotane. It focused on volunteers for screening for chronic non-communicable diseases. Epidemiological and clinical data were evaluated. Results: One hundred and twenty-nine cases of obesity were recorded (28%). Two hundred and eighty-two cases were overweight or obese (61.3%). The mean age was 49.55 years, with a standard deviation of 12.41 years. The age group [40 - 49 years] was the most representative, with 85 cases (30.1%), and the majority were female, with 264 cases (93.6%). Primary education was the most common, with 75 cases (46.3%). Grade 1 obesity concerned ninety-seven cases (75.2%), and diabetes was present in thirty cases (23%). Hypertension was present in ninety-five cases (33.7%). Obesity was more marked in the age group [40 - 49 years] with 45 cases (36%). Conclusion: Obesity and overweight are a major cause of morbidity and mortality. The development and implementation of a prevention and management program is essential.展开更多

Many people with hypertension have poorly controlled blood pressure and up to half of the adults with hypertension are unaware of their hypertensive status due to factors that bother on poor management and poor screening approaches. The implication is that people who have poor access to healthcare especially those in the rural communities are at increased risk of cardiovascular complications and all-cause mortality. Unfortunately, not much has been done to ascertain the burden of undiagnosed hypertension and associated risk factors in rural communities in Nigeria. Methods: We conducted a community-based cross-sectional study in a rural community in Imo State, Nigeria, on burden of undiagnosed hypertension with participants recruited via a multi-stage sampling method. An interviewer-administered questionnaire was used, and standardized instruments were applied to obtain, process and analyze the data. Tests of association between the independent variables and outcome were conducted using logistic regression. P-value of Results: A total of 380 adults participated in the study. The mean age was 44.2 years. The prevalence of undiagnosed hypertension was 35.8%. Logistic regression revealed that age, with the respondents in the age groups 26 - 35 years (OR = 10.647, 1.910 - 59.345, p-value = 0.007), 36 - 45 (OR = 3.680, 1.263 - 10.723, p-value = 0.017), 46 - 55 years (OR = 2.737, 1.114 - 6.727, p-value = 0.039), 56 - 65 years old (OR = 3.384, 1.610 - 7.115, p-value = 0.001);and being married (OR = 3.846, 1.118 - 13.233, p-value = 0.033), were independent risk factors for undiagnosed hypertension. Conclusion: The prevalence of undiagnosed hypertension in the rural population of South-East Nigeria is high. Younger age (26 - 35 years) had the highest odds of risk for occurrence of hypertension. Also being married was identified as a risk factor for undiagnosed hypertension.展开更多

However, this condition is increasingly observed in immunocompetent subjects. The aim of this study was to determine the endoscopic prevalence, clinical characteristics and risk factors for the occurrence of oesophageal mycosis in our department. Patients and Method: This was a prospective cross-sectional study of all patients who underwent oeso-gastroduodenal fibroscopy during the period from 1<sup>st </sup>January to 31<sup>st</sup> December 2022, i.e. one year, at the digestive endoscopy unit of the hepato-gastroenterology department of the Donka CHU national hospital in Conakry. All patients found to have oesophageal mycosis by FOGD were included. The endoscopy was performed using appropriate equipment: A Fujinon 4400 video endoscopy column;Three Fujinon EG 590 video gastroscopes;A hoover;Data were collected using a pre-established survey form and analysed using Epi info software version 6.0.4;Pearson’s Chi2 test as a test of independence and the exact 5% threshold ficher test. Results: Out of 1343 upper gastrointestinal endoscopies performed, 107 cases of oesophageal mycosis were found, representing a prevalence of 7.96%. The mean age was 40 years, with a male predominance of 55.42%. The sex ratio M/F was 1.24. The 45 and over age group was the most affected, with a prevalence of 40.43%, followed by the [35 - 45] age group, with a prevalence of 22.43%. Clinical symptoms were dominated by epigastralgia in 74.76% of cases, followed by odynophagia in 37.38% of cases, nausea and vomiting in 28.03% of cases, and pyrosis in 26.16% of cases. Oesophageal mycosis without oesophagitis was the most common endoscopic finding in 70% of cases. The main associated endoscopic lesions were erythemato-erosive and congestive gastropathy in 28.03% of cases, peptic oesophagitis (9.34%) and gastric ulcer (5.60%). The main risk factors found were positive HIV serology in 39.25% of cases, and diabetes in 24.30% of cases, with a statistically significant relationship of 0.02 and 0.01 respectively. Conclusion: Oesophageal mycosis is the most common opportunistic infection in patients with impaired cellular immunity. The prevalence of oesophageal mycosis in our series was 7.96%. This study enabled us to identify the main risk factors for the occurrence of oesophageal mycosis. Our country needs to step up its programme to combat and prevent immunodeficiency diseases, particularly HIV and diabetes.展开更多

Dispersal affects community dynamics and vegetation response to global change. The process of seed disposal is influenced by wind, which plays a crucial role in determining the distance and probability of seed dispersal. Existing models of seed dispersal consider wind direction but fail to incorporate wind intensity. In this paper, a novel seed disposal model was proposed in this paper, incorporating wind intensity based on relevant references. According to various climatic conditions, including temperate, arid, and tropical regions, three specific regions were selected to establish a wind dispersal model that accurately reflects the density function distribution of dispersal distance. Additionally, dandelions growth is influenced by a multitude of factors, encompassing temperature, humidity, climate, and various environmental variables that necessitate meticulous consideration. Based on Factor Analysis model, which completely considers temperature, precipitation, solar radiation, wind, and land carrying capacity, a conclusion is presented, indicating that the growth of seeds is primarily influenced by plant attributes and climate conditions, with the former exerting a relatively stronger impact. Subsequently, the remaining two plants were chosen based on seed weight, yielding consistent conclusion.展开更多

But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.展开更多

Although the deaths of neonates have reduced world over up to 3.6 million counts, Chilenje General Hospital continues to register significant numbers of neonatal sepsis. This study aimed at investigating the factors associated with neonatal sepsis at Chilenje General Hospital in Lusaka, Zambia. Methods: An institution based cross-sectional study design was conducted at Chilenje General Hospital. Data were collected by the use of a researcher designed questionnaire and analysed using SPSS version 25. Frequencies were used for descriptive analysis while bivariate analysis was used to establish association among risk factors and outcome variables. Variables with significant association at 5% level were further subjected to multivariate analysis at α ≤ 0.05. Results: The study showed that out of 156 neonates, 40.4% (63/156) developed neonatal sepsis. Maternal factors that projected the incidence of sepsis amongst neonates were distance to nearest health facility [AOR: 6.3 (95% CI: 1.8 - 21.3), p = 0.003], occupation [AOR: 5.8 (95% CI: 1.2 - 27.6), p = 0.026], number of antenatal visits [AOR: 6.3 (95% CI: 1.9 - 21.6), p = 0.003], number of vaginal examinations [AOR: 10.8 (95% CI: 2.8 - 42), p = 0.001], and pregnancy induced hypertension [AOR: 5.4 (95% CI: 1.4 - 20), p = 0.013]. Neonatal risk factor which projected the incidence of sepsis was Neonate’s age [AOR: 18.8 (95% CI: 4.9 - 72.5), p = 0.000]. Conclusions: The chance of developing neonatal sepsis was strongly correlated with both mother and child variables, according to the study. In order to lower the chance of the neonate acquiring sepsis, encouraging maternal antenatal care use would assist to detect risk factors during prenatal, perinatal and postnatal care and apply the proper therapies.展开更多

However, the nervous system is faced with a neurotropic virus that evolves chronically, sometimes creating neurological disorders directly or indirectly linked to stigmatization or therapeutic effects. Objective: to determine the prevalence of depression associated with suicidal risk (SR) and identify associated factors. Patients and method: This was a prospective descriptive and analytical study from January 1 to November 30, 2022, including all HIV-positive patients receiving or not receiving antiretroviral therapy. The study took place in the infectious diseases department of Brazzaville University Hospital. This department has an inpatient capacity of 36 beds, and an outpatient capacity of 25 patients per day, three times a week. This is the largest center for PVVIH in Brazzaville. The Patient Heath Questionnaire 9 (PHQ-9) was used to assess the degree of depression and suicidal risk. Therapeutic adherence was assessed using the Morisky questionnaire. Data were analyzed using SPSS version 23 software. Qualitative variables were expressed as numbers and percentages, and quantitative variables as means and standard deviations. Statistical tests were used according to their applicability criteria. For all tests, the significance threshold was set at 0.05. Results: A total of 150 patients were consulted, constituting the sample size. The prevalence of depression and suicidal risk was 32%. These patients had an average age of 42.83 ± 10.24 years, were female (n = 101;67.3%), Christian (n = 97;64%), single (n = 68;45.3%). Stigmatization (n = 75;50%) was the reason for attempted suicide. HIV was perceived as treatable (n = 103;68.7%), unlucky (n = 62;41.3%). Patients were WHO stage 1 (n = 105;70%). RS was present in 47 cases (31.3%). Factors associated with depression and suicidal risk were age (p = 0.000), residence (p = 0.028), suicide attempt (p = 0.000), desire to procreate (p = 0.000) and ARV (antiretrovirals) side effects (p Conclusion: The prevalence of depression and suicidal risk was high, in line with stigma and socio-economic conditions. The associated factors were in line with those identified in the literature. Mental health needs to be integrated into the overall care of people living with HIV.展开更多

文摘BACKGROUND Intensive care unit-acquired weakness(ICU-AW)is a common complication that significantly impacts the patient's recovery process,even leading to adverse outcomes.Currently,there is a lack of effective preventive measures.AIM To identify significant risk factors for ICU-AW through iterative machine learning techniques and offer recommendations for its prevention and treatment.METHODS Patients were categorized into ICU-AW and non-ICU-AW groups on the 14th day post-ICU admission.Relevant data from the initial 14 d of ICU stay,such as age,comorbidities,sedative dosage,vasopressor dosage,duration of mechanical ventilation,length of ICU stay,and rehabilitation therapy,were gathered.The relationships between these variables and ICU-AW were examined.Utilizing iterative machine learning techniques,a multilayer perceptron neural network model was developed,and its predictive performance for ICU-AW was assessed using the receiver operating characteristic curve.RESULTS Within the ICU-AW group,age,duration of mechanical ventilation,lorazepam dosage,adrenaline dosage,and length of ICU stay were significantly higher than in the non-ICU-AW group.Additionally,sepsis,multiple organ dysfunction syndrome,hypoalbuminemia,acute heart failure,respiratory failure,acute kidney injury,anemia,stress-related gastrointestinal bleeding,shock,hypertension,coronary artery disease,malignant tumors,and rehabilitation therapy ratios were significantly higher in the ICU-AW group,demonstrating statistical significance.The most influential factors contributing to ICU-AW were identified as the length of ICU stay(100.0%)and the duration of mechanical ventilation(54.9%).The neural network model predicted ICU-AW with an area under the curve of 0.941,sensitivity of 92.2%,and specificity of 82.7%.CONCLUSION The main factors influencing ICU-AW are the length of ICU stay and the duration of mechanical ventilation.A primary preventive strategy,when feasible,involves minimizing both ICU stay and mechanical ventilation duration.
文摘Approximately 20%of colorectal cancer(CRC)patients present with metastasis at diagnosis.Among Stage I-III CRC patients who undergo surgical resection,18%typically suffer from distal metastasis within the first three years following initial treatment.The median survival duration after the diagnosis of metastatic CRC(mCRC)is only 9 mo.mCRC is traditionally considered to be an advanced stage malignancy or is thought to be caused by incomplete resection of tumor tissue,allowing cancer cells to spread from primary to distant organs;however,increa-sing evidence suggests that the mCRC process can begin early in tumor development.CRC patients present with high heterogeneity and diverse cancer phenotypes that are classified on the basis of molecular and morphological alterations.Different genomic and nongenomic events can induce subclone diversity,which leads to cancer and metastasis.Throughout the course of mCRC,metastatic cascades are associated with invasive cancer cell migration through the circulatory system,extravasation,distal seeding,dormancy,and reactivation,with each step requiring specific molecular functions.However,cancer cells presenting neoantigens can be recognized and eliminated by the immune system.In this review,we explain the biological factors that drive CRC metastasis,namely,genomic instability,epigenetic instability,the metastatic cascade,the cancer-immunity cycle,and external lifestyle factors.Despite remarkable progress in CRC research,the role of molecular classification in therapeutic intervention remains unclear.This review shows the driving factors of mCRC which may help in identifying potential candidate biomarkers that can improve the diagnosis and early detection of mCRC cases.
文摘BACKGROUND Recently,research has linked Helicobacter pylori(H.pylori)stomach infection to colonic inflammation,mediated by toxin production,potentially impacting colorectal cancer occurrence.AIM To investigate the risk factors for post-colon polyp surgery,H.pylori infection,and its correlation with pathologic type.METHODS Eighty patients who underwent colon polypectomy in our hospital between January 2019 and January 2023 were retrospectively chosen.They were then randomly split into modeling(n=56)and model validation(n=24)sets using R.The modeling cohort was divided into an H.pylori-infected group(n=37)and an H.pylori-uninfected group(n=19).Binary logistic regression analysis was used to analyze the factors influencing the occurrence of H.pylori infection after colon polyp surgery.A roadmap prediction model was established and validated.Finally,the correlation between the different pathological types of colon polyps and the occurrence of H.pylori infection was analyzed after colon polyp surgery.RESULTS Univariate results showed that age,body mass index(BMI),literacy,alcohol consumption,polyp pathology type,high-risk adenomas,and heavy diet were all influential factors in the development of H.pylori infection after intestinal polypectomy.Binary multifactorial logistic regression analysis showed that age,BMI,and type of polyp pathology were independent predictors of the occurrence of H.pylori infection after intestinal polypectomy.The area under the receiver operating characteristic curve was 0.969[95%confidence interval(95%CI):0.928–1.000]and 0.898(95%CI:0.773–1.000)in the modeling and validation sets,respectively.The slope of the calibration curve of the graph was close to 1,and the goodness-of-fit test was P>0.05 in the two sets.The decision analysis curve showed a high rate of return in both sets.The results of the correlation analysis between different pathological types and the occurrence of H.pylori infection after colon polyp surgery showed that hyperplastic polyps,inflammatory polyps,and the occurrence of H.pylori infection were not significantly correlated.In contrast,adenomatous polyps showed a significant positive correlation with the occurrence of H.pylori infection.CONCLUSION Age,BMI,and polyps of the adenomatous type were independent predictors of H.pylori infection after intestinal polypectomy.Moreover,the further constructed column-line graph prediction model of H.pylori infection after intestinal polypectomy showed good predictive ability.
文摘Objective:This study aimed to identify predictive factors for percutaneous nephrolithotomy(PCNL)bleeding risks.With better risk stratification,bleeding in high-risk patient can be anticipated and facilitates early identification.Methods:A prospective observational study of PCNL performed at our institution was done.All adults with radio-opaque renal stones planned for PCNL were included except those with coagulopathy,planned for additional procedures.Factors including gender,co-morbidities,body mass index,stone burden,puncture site,tract dilatation size,operative position,surgeon's seniority,and operative duration were studied using stepwise multivariate regression analysis to identify the predictive factors associated with higher estimated hemoglobin(Hb)deficiency.Results:Overall,4.86%patients(n=7)received packed cells transfusion.The mean estimated Hb deficiency was 1.3(range 0-6.5)g/dL and the median was 1.0 g/dL.Stepwise multivariate regression analysis revealed that absence of hypertension(p=0.024),puncture site(p=0.027),and operative duration(p=0.023)were significantly associated with higher estimated Hb deficiency.However,the effect sizes are rather small with partial eta-squared of 0.037,0.066,and 0.038,respectively.Observed power obtained was 0.621,0.722,and 0.625,respectively.Other factors studied did not correlate with Hb difference.Conclusion:Hypertension,puncture site,and operative duration have significant impact on estimated Hb deficiency during PCNL.However,the effect size is rather small despite adequate study power obtained.Nonetheless,operative position(supine or prone),puncture number,or tract dilatation size did not correlate with Hb difference.The mainstay of reducing bleeding in PCNL is still meticulous operative technique.Our study findings also suggest that PCNL can be safely done by urology trainees under supervision in suitably selected patient,without increasing risk of bleeding.

文摘BACKGROUND Duodenal cancer is one of the most common subtypes of small intestinal cancer,and distant metastasis(DM)in this type of cancer still leads to poor prognosis.Although nomograms have recently been used in tumor areas,no studies have focused on the diagnostic and prognostic evaluation of DM in patients with primary duodenal cancer.AIM To develop and evaluate nomograms for predicting the risk of DM and person-alized prognosis in patients with duodenal cancer.METHODS Data on duodenal cancer patients diagnosed between 2010 and 2019 were extracted from the Surveillance,Epidemiology,and End Results database.Univariate and multivariate logistic regression analyses were used to identify independent risk factors for DM in patients with duodenal cancer,and univariate and multivariate Cox proportional hazards regression analyses were used to determine independent prognostic factors in duodenal cancer patients with DM.Two novel nomograms were established,and the results were evaluated by receiver operating characteristic(ROC)curves,calibration curves,and decision curve analysis(DCA).RESULTS A total of 2603 patients with duodenal cancer were included,of whom 457 cases(17.56%)had DM at the time of diagnosis.Logistic analysis revealed independent risk factors for DM in duodenal cancer patients,including gender,grade,tumor size,T stage,and N stage(P<0.05).Univariate and multivariate COX analyses further identified independent prognostic factors for duodenal cancer patients with DM,including age,histological type,T stage,tumor grade,tumor size,bone metastasis,chemotherapy,and surgery(P<0.05).The accuracy of the nomograms was validated in the training set,validation set,and expanded testing set using ROC curves,calibration curves,and DCA curves.The results of Kaplan-Meier survival curves(P<0.001)indicated that both nomograms accurately predicted the occurrence and prognosis of DM in patients with duodenal cancer.CONCLUSION The two nomograms are expected as effective tools for predicting DM risk in duodenal cancer patients and offering personalized prognosis predictions for those with DM,potentially enhancing clinical decision-making.
文摘Introduction: Non-communicable diseases constitute a major public health problem, due to their morbi-mortality. The aim was to study knowledge of cardiovascular risk factors among residents of Dakar. Patients and Methods: This was a descriptive cross-sectional study. Our investigations were recruited over a six-month period (October 17, 2021 to March 21, 2022). Results: Two hundred and twenty-six (226) patients were enrolled. The mean age was 45.9 years. The under-40 age group was the most represented with 37.2%. There were 129 men (57.1%), giving a male/female sex ratio of 1.33. The highest level was represented by 159 people (70.4%). Those who responded (heart disease) were in the majority (38.1%). Hypertension was the most common CVD for 101 people (44.7%). One hundred and ninety (190) people (84%) knew the risk factors for CVD. Good knowledge of risk factors concerned 103 people (54.2%). Obesity was the best-known risk factor in 156 cases (69%). The media was the most important source of information for 121 people (53.5%). Hypertensives were the most represented with 8.4%. One hundred and thirty (130) people (57.5%) had previously paid attention to these FDRCVs. Awareness campaigns were the most effective means of communication for 170 cases (75.2%). Sixteen (16) people (35.6%) were taking antihypertensive medication. Walking was the most popular physical activity for 102 people (45%). People with a balanced diet were in the majority, with 174 respondents (77.0%). Conclusion: NCDs are a major cause of morbidity and mortality. It is essential to develop and implement a prevention and management program.
文摘The World Health Organization states that foodborne diseases are a worldwide public health issue. Although street foods can provide nutritious and affordable ready-to-eat meals for city dwellers, their health risks can outweigh the benefits. A cross-sectional study was conducted in the Bamako district, focusing on street food vendors near schools, universities, extensive markets, administrative centers, and major roads. We aimed to sample fifty (50) sellers per municipality, making 300 sellers for the Bamako district. We developed a survey sheet to collect data, and six teams rotated between the municipalities each month. Before starting the collection, the teams were provided administrative papers approved by the municipal authority. The survey revealed three types of sales sites: fixed (65%), semi-fixed (30%), and mobile (4.40%). The proportion of sellers was 26.8%, 23.2%, 19.7%, and 4.2% in municipalities III, IV, and I. In municipalities I, II, III, IV, and VI, respectively, 92%, 95.70%, 93%, 87.2%, and 100% of the sellers were female. The age distribution of sellers was 65.63%, 46.81%, 40.82%, 38.30%, 36.17%, 36%, and 32% in the 25-34 and 35 - 44 age groups. Illiteracy rates were 59.20%, 61.70%, 55.30%, 75%, and 56% in municipalities I, II, III, IV, and VI, respectively. The study identified two categories of sellers: 48.3% in type 1 and 51.7% in type 2. The first category comprised 154 sellers, and the second 165 sellers. The survey found that 66.00%, 56.00%, 48.90%, 44.90%, 38.30%, and 34.40% of municipal V, VI, III, I, II, and IV sales sites were open-air. In municipality I, 63.30% of the sites were under hangars, while in municipalities II and IV, the corresponding percentages were 51.10% and 59.40%, respectively. Moreover, 46.00%, 31.90%, 31.30%, 30.60%, and 27.70% of the sites in municipalities VI, II, IV, I, and III were located next to gutters. In conclusion, this study identified several factors that could compromise the quality of street foods sold in the six municipalities of Bamako.
文摘The study took a comprehensive approach to understanding mastitis in lactating camels, a disease that significantly impacts milk quantity and quality. This complex and multifactorial disease poses a significant challenge to dairy camel farming, particularly in Somalia. The studys objective was to determine the prevalence of mastitis and the risk factors associated with it among lactating camels on dairy farms in Benadir, Somalia. To achieve this, a cross-sectional study was conducted from May to September 2022 in the Benadir region of Somalia. A total of 96 lactating camels underwent examination using the California Mastitis Test (CMT) to identify clinical and subclinical mastitis cases. Additionally, a questionnaire survey was conducted among 20 farm employees/owners to gather information on hygiene practices, parity, lactation stage, tick infestation, and the presence of udder/teat lesions. Data regarding parity and lactation stage were obtained through owner interviews. The data collected on specifically designed forms were recorded and entered into a Microsoft Excel spreadsheet for analysis using SPSS version 20 statistical software, ensuring a comprehensive and reliable analysis of the data. The studys findings revealed a significant prevalence of camel mastitis, with 34.4% (33/96) of lactating camels affected and clinical and subclinical cases constituting 5.2% and 29.2%, respectively. Quarter-level prevalence was 46.3%, with clinical and subclinical mastitis at 4.7% and 41.6%, respectively. The study also identified significant associations (P < 0.05) among risk factors such as stage of lactation, parity, and age, indicating a higher susceptibility to mastitis in older camels during early lactation compared to those in late lactation and younger camels. These findings underscore the crucial role of inadequate hygienic conditions on camel farms and udder tick infestations in driving the elevated prevalence of mastitis, highlighting the need for improved management practices in dairy farming in Benadir, Somalia. Effective interventions, including improved management practices and extension services, are essential to reduce the burden of mastitis in dairy camels.
文摘Introduction: Hepatitis B virus (HBV) infection is a major public health problem in Cameroon. Garoua city is the headquarters of the North Region of Cameroon, where the HBV prevalence is among the highest of the country. The aim of this study was to determine the prevalence of HBsAg carriage and associated factors among persons incarcerated in the Garoua Central Prison. Methods: It was a cross-sectional study conducted from July 1 to July 31, 2023 at the Garoua Central prison. We included all prisoners willing to participate in the study and who gave their verbal consent. We collected data using a pre-established data entry form and we used rapid test for blood screening for HBV surface antigen (HBs Ag) with ELISA confirmation. Data were analyzed using the R<sup>®</sup> software for Windows. After the univariate analysis, we selected associated variables to HBV infection with p-value p-value was set at 5%. Results: We included 1389 prisoners out of which 97.6% were male. The median age (IQR) of the study population was 28 (23 - 35) years. The median (IQR) duration of incarceration was 12 (6 - 26) months and the mean (±sd) number of incarcerations was 1.24 (±0.6). HBV prevalence was estimated at 14.8% (95% CI: 13.0 - 16.7). Upon uni- and multivariate analysis, no risk factor was significantly associated with viral hepatitis B infection in our study population. Conclusion: The prevalence of Hepatitis B was high in the Garoua Central Prison, but there were no additional risk factors for HBV infection. There is a need to include the Garoua Central Prison and by the way other prisons in the country in the chronic viral hepatitis care program.
文摘Introduction: Hypertension is a real public health issue and its control is very difficult. 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.
文摘Background: The coronavirus disease (COVID-19) pandemic has impacted perinatal women’s mental health. However, protective factors associated with depression among pregnant Japanese women during the pandemic have not been reported. Purpose: The present study investigated the risk and protective factors associated with depression and anxiety among pregnant women during the COVID-19 pandemic. Methods: An online questionnaire was administered to 157 pregnant women between October 2022 and May 2023 at two general hospitals in Japan. The Japanese versions of the Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 (GAD-7) were used to assess symptoms of depression and anxiety. The χ<sup>2</sup> test or Fisher’s exact test and multivariate logistic regression model were used to examine factors associated with depression and anxiety among pregnant women. Results: Overall, 47.1% and 35.7% of the pregnant women reported depressive and anxiety symptoms, respectively. A “history of mental illness” was a risk factor for depression and anxiety among pregnant women during the COVID-19 pandemic. Additionally, unmarried status was a risk factor for anxiety among pregnant women, whereas outdoor and indoor exercises were protective factors against depression and anxiety, respectively. Conclusions: Exercise may have protected pregnant women from depression and anxiety during the COVID-19 pandemic. Encouraging exercise may help maintain the mental health of pregnant women who do not have exercise restrictions.
文摘Introduction: Obesity and overweight are a public health problem. The general objective was to determine the epidemiological aspects of obesity, overweight and associated risk factors in a semi-urban environment. Patients and Methods: This was a cross-sectional, descriptive study conducted on November 28 and 29, 2023 in Sébikotane. It focused on volunteers for screening for chronic non-communicable diseases. Epidemiological and clinical data were evaluated. Results: One hundred and twenty-nine cases of obesity were recorded (28%). Two hundred and eighty-two cases were overweight or obese (61.3%). The mean age was 49.55 years, with a standard deviation of 12.41 years. The age group [40 - 49 years] was the most representative, with 85 cases (30.1%), and the majority were female, with 264 cases (93.6%). Primary education was the most common, with 75 cases (46.3%). Grade 1 obesity concerned ninety-seven cases (75.2%), and diabetes was present in thirty cases (23%). Hypertension was present in ninety-five cases (33.7%). Obesity was more marked in the age group [40 - 49 years] with 45 cases (36%). Conclusion: Obesity and overweight are a major cause of morbidity and mortality. The development and implementation of a prevention and management program is essential.
文摘Background: Cardiovascular diseases are the leading cause of death globally and hypertension is a major contributor to this burden. Many people with hypertension have poorly controlled blood pressure and up to half of the adults with hypertension are unaware of their hypertensive status due to factors that bother on poor management and poor screening approaches. The implication is that people who have poor access to healthcare especially those in the rural communities are at increased risk of cardiovascular complications and all-cause mortality. Unfortunately, not much has been done to ascertain the burden of undiagnosed hypertension and associated risk factors in rural communities in Nigeria. Methods: We conducted a community-based cross-sectional study in a rural community in Imo State, Nigeria, on burden of undiagnosed hypertension with participants recruited via a multi-stage sampling method. An interviewer-administered questionnaire was used, and standardized instruments were applied to obtain, process and analyze the data. Tests of association between the independent variables and outcome were conducted using logistic regression. P-value of Results: A total of 380 adults participated in the study. The mean age was 44.2 years. The prevalence of undiagnosed hypertension was 35.8%. Logistic regression revealed that age, with the respondents in the age groups 26 - 35 years (OR = 10.647, 1.910 - 59.345, p-value = 0.007), 36 - 45 (OR = 3.680, 1.263 - 10.723, p-value = 0.017), 46 - 55 years (OR = 2.737, 1.114 - 6.727, p-value = 0.039), 56 - 65 years old (OR = 3.384, 1.610 - 7.115, p-value = 0.001);and being married (OR = 3.846, 1.118 - 13.233, p-value = 0.033), were independent risk factors for undiagnosed hypertension. Conclusion: The prevalence of undiagnosed hypertension in the rural population of South-East Nigeria is high. Younger age (26 - 35 years) had the highest odds of risk for occurrence of hypertension. Also being married was identified as a risk factor for undiagnosed hypertension.
文摘Introduction: Oesophageal mycosis (OM) is one of the most common opportunistic infections in patients infected with HIV (Human Immunodeficiency Virus). However, this condition is increasingly observed in immunocompetent subjects. The aim of this study was to determine the endoscopic prevalence, clinical characteristics and risk factors for the occurrence of oesophageal mycosis in our department. Patients and Method: This was a prospective cross-sectional study of all patients who underwent oeso-gastroduodenal fibroscopy during the period from 1<sup>st </sup>January to 31<sup>st</sup> December 2022, i.e. one year, at the digestive endoscopy unit of the hepato-gastroenterology department of the Donka CHU national hospital in Conakry. All patients found to have oesophageal mycosis by FOGD were included. The endoscopy was performed using appropriate equipment: A Fujinon 4400 video endoscopy column;Three Fujinon EG 590 video gastroscopes;A hoover;Data were collected using a pre-established survey form and analysed using Epi info software version 6.0.4;Pearson’s Chi2 test as a test of independence and the exact 5% threshold ficher test. Results: Out of 1343 upper gastrointestinal endoscopies performed, 107 cases of oesophageal mycosis were found, representing a prevalence of 7.96%. The mean age was 40 years, with a male predominance of 55.42%. The sex ratio M/F was 1.24. The 45 and over age group was the most affected, with a prevalence of 40.43%, followed by the [35 - 45] age group, with a prevalence of 22.43%. Clinical symptoms were dominated by epigastralgia in 74.76% of cases, followed by odynophagia in 37.38% of cases, nausea and vomiting in 28.03% of cases, and pyrosis in 26.16% of cases. Oesophageal mycosis without oesophagitis was the most common endoscopic finding in 70% of cases. The main associated endoscopic lesions were erythemato-erosive and congestive gastropathy in 28.03% of cases, peptic oesophagitis (9.34%) and gastric ulcer (5.60%). The main risk factors found were positive HIV serology in 39.25% of cases, and diabetes in 24.30% of cases, with a statistically significant relationship of 0.02 and 0.01 respectively. Conclusion: Oesophageal mycosis is the most common opportunistic infection in patients with impaired cellular immunity. The prevalence of oesophageal mycosis in our series was 7.96%. This study enabled us to identify the main risk factors for the occurrence of oesophageal mycosis. Our country needs to step up its programme to combat and prevent immunodeficiency diseases, particularly HIV and diabetes.
文摘A weed is a plant that thrives in areas of human disturbance, such as gardens, fields, pastures, waysides, and waste places where it is not intentionally cultivated. Dispersal affects community dynamics and vegetation response to global change. The process of seed disposal is influenced by wind, which plays a crucial role in determining the distance and probability of seed dispersal. Existing models of seed dispersal consider wind direction but fail to incorporate wind intensity. In this paper, a novel seed disposal model was proposed in this paper, incorporating wind intensity based on relevant references. According to various climatic conditions, including temperate, arid, and tropical regions, three specific regions were selected to establish a wind dispersal model that accurately reflects the density function distribution of dispersal distance. Additionally, dandelions growth is influenced by a multitude of factors, encompassing temperature, humidity, climate, and various environmental variables that necessitate meticulous consideration. Based on Factor Analysis model, which completely considers temperature, precipitation, solar radiation, wind, and land carrying capacity, a conclusion is presented, indicating that the growth of seeds is primarily influenced by plant attributes and climate conditions, with the former exerting a relatively stronger impact. Subsequently, the remaining two plants were chosen based on seed weight, yielding consistent conclusion.
文摘Background: Tenofovir (TFV) is widely used to treat patients with hepatitis B virus (HBV) infection. But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.
文摘Background: Neonatal sepsis is known to result in 26% of mortalities in children below the age of five worldwide, countries in Sub-Saharan African recording the highest deaths. Although the deaths of neonates have reduced world over up to 3.6 million counts, Chilenje General Hospital continues to register significant numbers of neonatal sepsis. This study aimed at investigating the factors associated with neonatal sepsis at Chilenje General Hospital in Lusaka, Zambia. Methods: An institution based cross-sectional study design was conducted at Chilenje General Hospital. Data were collected by the use of a researcher designed questionnaire and analysed using SPSS version 25. Frequencies were used for descriptive analysis while bivariate analysis was used to establish association among risk factors and outcome variables. Variables with significant association at 5% level were further subjected to multivariate analysis at α ≤ 0.05. Results: The study showed that out of 156 neonates, 40.4% (63/156) developed neonatal sepsis. Maternal factors that projected the incidence of sepsis amongst neonates were distance to nearest health facility [AOR: 6.3 (95% CI: 1.8 - 21.3), p = 0.003], occupation [AOR: 5.8 (95% CI: 1.2 - 27.6), p = 0.026], number of antenatal visits [AOR: 6.3 (95% CI: 1.9 - 21.6), p = 0.003], number of vaginal examinations [AOR: 10.8 (95% CI: 2.8 - 42), p = 0.001], and pregnancy induced hypertension [AOR: 5.4 (95% CI: 1.4 - 20), p = 0.013]. Neonatal risk factor which projected the incidence of sepsis was Neonate’s age [AOR: 18.8 (95% CI: 4.9 - 72.5), p = 0.000]. Conclusions: The chance of developing neonatal sepsis was strongly correlated with both mother and child variables, according to the study. In order to lower the chance of the neonate acquiring sepsis, encouraging maternal antenatal care use would assist to detect risk factors during prenatal, perinatal and postnatal care and apply the proper therapies.
文摘Introduction: Highly active antiretroviral tritherapies have improved the quality of life of people living with HIV (PVVIH) and extended their life expectancy. However, the nervous system is faced with a neurotropic virus that evolves chronically, sometimes creating neurological disorders directly or indirectly linked to stigmatization or therapeutic effects. Objective: to determine the prevalence of depression associated with suicidal risk (SR) and identify associated factors. Patients and method: This was a prospective descriptive and analytical study from January 1 to November 30, 2022, including all HIV-positive patients receiving or not receiving antiretroviral therapy. The study took place in the infectious diseases department of Brazzaville University Hospital. This department has an inpatient capacity of 36 beds, and an outpatient capacity of 25 patients per day, three times a week. This is the largest center for PVVIH in Brazzaville. The Patient Heath Questionnaire 9 (PHQ-9) was used to assess the degree of depression and suicidal risk. Therapeutic adherence was assessed using the Morisky questionnaire. Data were analyzed using SPSS version 23 software. Qualitative variables were expressed as numbers and percentages, and quantitative variables as means and standard deviations. Statistical tests were used according to their applicability criteria. For all tests, the significance threshold was set at 0.05. Results: A total of 150 patients were consulted, constituting the sample size. The prevalence of depression and suicidal risk was 32%. These patients had an average age of 42.83 ± 10.24 years, were female (n = 101;67.3%), Christian (n = 97;64%), single (n = 68;45.3%). Stigmatization (n = 75;50%) was the reason for attempted suicide. HIV was perceived as treatable (n = 103;68.7%), unlucky (n = 62;41.3%). Patients were WHO stage 1 (n = 105;70%). RS was present in 47 cases (31.3%). Factors associated with depression and suicidal risk were age (p = 0.000), residence (p = 0.028), suicide attempt (p = 0.000), desire to procreate (p = 0.000) and ARV (antiretrovirals) side effects (p Conclusion: The prevalence of depression and suicidal risk was high, in line with stigma and socio-economic conditions. The associated factors were in line with those identified in the literature. Mental health needs to be integrated into the overall care of people living with HIV.
