Introduction: Urinary tract infection is one of the most frequent public health problems in the world and concerns all ages. Objective: To describe the epidemiological, clinical and biological profile of urinary tract infection in the internal medicine unit of the Fousseyni Daou hospital in Kayes. Methodology: It was a descriptive and cross-sectional study with retrospective data collection which took place from January 1 to December 31, 2020 at the Internal Medicine Unit of the Fousseyni Daou Hospital in Kayes. It covered all outpatients and hospitalized patients presenting with a urinary tract infection during the study period. Results: We identified 79 cases of urinary tract infection out of 145 requests for ECBU, that is a positivity rate of 53.10% and out of a total of 1883 admissions that is a hospital prevalence of 4.19%. The age groups of 36 to 45 years and 46 to 55 years were more represented in 28 cases (35.44%) and 25 cases (31.64%) with an average age of 45 years ± 10. The female sex was predominant, 42 cases (53.16%) with a sex ratio of 0.88. Housewives were more represented 28 cases (34.44%). The majority of patients resided in rural areas 49 cases (62.03%). The history was dominated by the following pathologies: hypertension 48.10%, diabetes 36.70% and gastropathy 30.37%. The main clinical manifestations were: Urinary burning 67 cases (84.81%), Dysuria 65 cases (82.27%), Pelvic pain 59 cases (74.68%), Fever 57 cases (72.15%). The epidemiological profile of the isolated strains was dominated by enterobacteriaceae, followed by gram-positive cocci and gram-negative bacilli. The main bacteria responsible for urinary tract infections in order of frequency: Escherichia coli (45.56%), Klebsiella pneumoniae (11.39%), Pseudomonas aeruginosa (8.86%), Staphylococcus aureus (7.59%), Streptococcus sp (6.33%), Enterobacter cloacae (3.79%), Acinetobacter sp (3.79%). The study of the susceptibility and resistance profiles of the isolated strains showed significant sensitivity of enterobacteriaceae to colistin and resistance to amoxicillin and to the amoxicillin + clavulanic acid combination. Conclusion: Urinary tract infections are a major public health problem since they are responsible for significant morbidity and mortality and a high cost of care. Knowledge of the epidemiological-clinical and bacteriological profile of these infections is essential for efficient management.

Analysis of clinical characteristics and risk factors between elderly patients with severe and nonsevere Omicron variant infection

BACKGROUND Coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),has led to millions of confirmed cases and deaths worldwide.Elderly patients are at high risk of developing and dying from COVID-19 due to advanced age,decreased immune function,intense inflammatory response,and comorbidities.Shanghai has experienced a wave of infection with Omicron,a new variant of SARS-CoV-2,since March 2022.There is a pressing need to identify clinical features and risk factors for disease progression among elderly patients with Omicron infection to provide solid evidence for clinical policy-makers,public health officials,researchers,and the general public.AIM To investigate clinical characteristic differences and risk factors between elderly patients with severe and nonsevere Omicron SARS-CoV-2 variant infection.METHODS A total of 328 elderly patients with COVID-19 admitted to the Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 2022 to June 2022 were enrolled and divided into a severe group(82 patients)and a nonsevere group(246 patients)according to the diagnosis and treatment protocol of COVID-19(version 7).The clinical data and laboratory results of both groups were collected and compared.A chi-square test,t test,Mann-Whitney U test,hierarchical log-rank test,univariate and multivariate logistic regression,and hierarchical analyses were used to determine significant differences.RESULTS The severe group was older(84 vs 74 years,P<0.001),included more males(57.3%vs 43.9%,P=0.037),had a lower vaccination rate(P<0.001),and had a higher proportion of comorbidities,including chronic respiratory disease(P=0.001),cerebral infarction(P<0.001),chronic kidney disease(P=0.002),and neurodegenerative disease(P<0.001),than the nonsevere group.In addition,severe disease patients had a higher inflammatory index(P<0.001),greater need for symptomatic treatment(P<0.001),longer hospital stay(P=0.011),extended viral shedding time(P=0.014),and higher mortality than nonsevere disease patients(P<0.001).No difference was observed in the application of Paxlovid in the severe and nonsevere groups(P=0.817).Oxygen saturation,cerebral infarction,and D-dimer were predictive factors for developing severe disease in patients with COVID-19,with D-dimer having an excellent role(area under the curve:90.1%,95%CI:86.1-94.0%).In addition,D-dimer was a risk factor for developing severe COVID-19 according to multivariate stratified analysis.CONCLUSION The clinical course of severe COVID-19 is complex,with a higher need for symptomatic treatment.D-dimer is a suitable biomarker for identifying patients at risk for developing severe COVID-19.

Peripheral T-lymphocyte subpopulations in different clinical stages of chronic HBV infection correlate with HBV load

AIM: To characterize the peripheral T-cell subpopulation profiles and their correlation with hepatitis B virus (HBV) replication in different clinical stages of chronic HBV infection.METHODS: A total of 422 patients with chronic HBV infection were enrolled in this study. The patients were divided into three stages: immune-tolerant stage, immune active stage, and immune-inactive carrier stage. Composition of peripheral T-cell subpopulations was determined by flow cytometry. HBV markers were detected by enzyme-linked immunosorbent assay. SerumHBV DNA load was assessed by quantitative real-time polymerase chain reaction.RESULTS: CD8+ T-cells were significantly higher in patients at the immune-tolerant stage than in patients at the immune-active and -inactive carrier stages (36.87 ± 7.58 vs 34.37 ± 9.07, 36.87 ± 7.58 vs 28.09 ± 5.64, P < 0.001). The peripheral blood in patients at the immune-tolerant and immune active stages contained more CD8+ T-cells than CD4+ T-cells (36.87 ± 7.58 vs 30.23 ± 6.35, 34.37 ± 9.07 vs 30.92 ± 7.40, P < 0.01), whereas the peripheral blood in patients at the immune-inactive carrier stage and in normal controls contained less CD8+ T-cells than CD4+ T-cells (28.09 ± 5.64 vs 36.85 ± 6.06, 24.02 ± 4.35 vs 38.94 ± 3.39, P < 0.01). ANOVA linear trend test showed that CD8+ T-cells were signif icantly increased in patients with a high viral load (39.41 ± 7.36, 33.83 ± 7.50, 31.81 ± 5.95 and 26.89 ± 5.71, P < 0.001), while CD4+ T-cells were signif icantly increased in patients with a low HBV DNA load (37.45 ± 6.14, 33.33 ± 5.61, 31.58 ± 6.99 and 27.56 ± 5.49, P < 0.001). Multiple regression analysis displayed that log copies of HBV DNA still maintained its highly signif icant coefficients for T-cell subpopulations, and was the strongest predictors for variations in CD3+, CD4+ and CD8+ cells and CD4+/CD8+ ratio after adjustment for age at HBV-infection, maternal HBV-infection status, presence of hepatitis B e antigen and HBV mutation.CONCLUSION: Differences in peripheral T-cell subpopulation profi les can be found in different clinical stages of chronic HBV infection. T-cell impairment is signifi cantly associated with HBV load.

An Analysis of Clinical Characters of Inpatients with Infection in the Department of Endocrinology

Objective:To analyze the clinical characters of 812 inpatients with infection in the Department of Endocrinology.Methods:Retrospective exhibition of these patients'clinical characters included undergoing diseases,infectious organs,history illness,blood glucose and glycosylated hemoglobin(HbA1C),biochemical indicators,pathogens training description and results,medical imagines,antibiotic utilization,length of stay and hospital costs,final diagnosis and situations.Results:Non-diabetic patients accounted for 176(21.67%),who were the cases of untreated well hyperthyroidism,mainly suffered with respiratory tract infection.Diabetic patients accounted for 636(78.33%).In the type2 diabetes patients 376(59.12)suffered with urinary tract infection.192(30.19%)suffered with respiratory system infection,124(19.50%)were accompanied with diabetic foot infection,which had 74(59.67%)patients with HbA1C>9.0%.Statistical comparisons showed that the days of antibiotic use and average length of stay in hospital per capita in patients with HbA1C≥8%were more than ones with HbA1C<8%in those with diabetic infections(P<0.01).The days of antibiotic use per capita in patients with HbA1C>9%were more than ones with HbA1C<7%in those with diabetic foot infections(P<0.01).Conclusion:Endocrine diseases lack rigid and effective long-term control,which may result in the complications involved with urinary tract,respiratory tract and infections in other organs.The time of hospitalization per capita and the duration of antibiotic use rise are longer in diabetic patients with poor blood sugar control and diabetic foot infection.

Assessing the Effectiveness of Montelukast Sodium in Managing Pulmonary Infections in Lung Cancer Patients

Objective:To investigate the efficacy of montelukast sodium in the treatment of lung cancer patients with pulmonary infections.Methods:A total of 330 patients diagnosed with lung cancer and pulmonary infection,who were admitted to the First Affiliated Hospital of Xi’an Medical University from 2020 to 2022,were selected as research subjects.They were randomly divided into two groups:a control group receiving conventional treatment and an observation group receiving conventional treatment combined with montelukast sodium.Each group consisted of 165 cases.The time required for clinical symptom improvement,the resolution of lung infection signs,and the levels of serum inflammatory factors before and after treatment were compared between the two groups.Results:The observation group exhibited significantly faster improvement in clinical symptoms compared to the control group(P<0.001).ELISA assays were conducted to detect the expression levels of IL-1β,IL-6,IL-8,and TNF-αin the serum of both groups at 1 week and 2 weeks into the treatment.The results indicated that,as the treatment progressed,the observation group displayed significantly lower levels of the four serum inflammatory factors compared to the control group(P<0.001).Conclusion:Montelukast sodium demonstrates efficacy in the treatment of patients with lung cancer complicated by pulmonary infections.These findings suggest its potential for further verification and clinical application.

Correlates of Hepatitis B Virus Infection among Antenatal Clinic Attendees of Volta Regional Hospital, Ho, Volta Region, Ghana

Hepatitis B virus (HBV) infection remains a global health problem. With about 380 million chronic carriers of the HBV virus, there are over two million global deaths annually. Ghana is among the high endemic countries in Africa, with HBV prevalence ranging from 4.8% to 12.3% in the general population, 10.8% to 12.7% in blood donors and about 10.6% in antenatal clinic (ANC) attendees. The main objectives of this study were to test how socioeconomic factors, risky behaviors, knowledge and awareness of HBV infection correlate with actual HBV status among antenatal clinic attendees and to determine the predictors of HBV testing among ANC attendees. The study employed random sampling technique to sample 500 pregnant women, at mothers’ clinic of Volta Regional Hospital, Ho, Ghana. A structured questionnaire was used to collect information on socio-demographic characteristics, Hepatitis B status, possible risk factors, awareness and knowledge levels of HBV infection. Cross tabulation and the chi-square (χ2) statistic were used to determine statistical independence or association of study variables. Kruskal-Wallis test was applied to test for the differences in HBV knowledge scores across HBV status and levels of HBV awareness;and the binomial regression model was used to determine the predictors of HBV testing among ANC attendees. It is evident that age, religion, ethnicity, educational level, blood transfusion, number of blood transfusions, gravidity, parity, awareness of HBV and monthly income were associated with HBV status. Results of the Binomial Logistic Regression model indicate that Age (p = 0.03), Education level (p = 0.04), Religion (p = 0.04), Ethnicity (p = 0.00) and Blood transfusion (p = 0.04) were significant (p 0.05) predictors of HBV testing. Knowledge of HBV status enables patients to seek early treatment, facilitates referral for social support and counseling. We recommend that the Ministry of Health should carry effective education on HBV and its prevention for women of child-bearing age.

The clinical characteristics and risk factors for necrotizing soft tissue infection in children

Importance:Necrotizing soft tissue infection(NSTI)is a serious infectious disease.However,the early clinical manifestations and indicators of NSTI in children are still unclear.Objective:The purpose of this study was to analyze the clinical characteristics and risk factors of NSTI in pediatric patients.Methods:A total of 127 children with skin and soft tissue infection(SSTI)were treated at our hospital and divided into two groups:the NSTI group and the non-NSTI group,based on their discharge diagnosis from January 2011 to December 2022.Then,we collected and analyzed the clinical characteristics and risk factors of all patients,including sex and age,disease inducement,admission temperature,local skin manifestations,infection site,the presence of sepsis,bacterial culture,and laboratory indicators.Results:In our study,there was a statistical difference in the age distribution and disease inducement between NSTI and non-NSTI groups.The occurrence of local skin manifestations(blisters/bullae and ecchymosis)and the presence of sepsis significantly increased in the NSTI group compared to the non-NSTI group.Additionally,only the platelet count on laboratory tests was statistically different between the NSTI and non-NSTI groups.Finally,the logistic regression analysis suggested that local skin manifestations such as blisters/bullae,and ecchymosis,as well as the presence of sepsis,were identified as risk factors for NSTI.Interpretation:Children with SSTI and skin manifestations such as blisters/bullae,ecchymosis,and the presence of sepsis are at a higher risk of developing NSTI.These symptoms serve as useful indicators for early detection of NSTI.

Clinical analysis of patients with deep sternal wound infection-induced sepsis:a retrospective cohort study

Background:This study aimed to summarize the clinical characteristics of patients with deep sternal wound infection-induced sepsis after median sternotomy and improve the treatment outcomes of infection-related sepsis.Methods:A retrospective cohort study was conducted on 21 patients with deep sternal wound infection-induced sepsis after median sternotomy who were admitted to the Department of Critical Care.The clinical manifestations,laboratory test results,infection control,and organ and nutritional support of the patients were summarized,and the follow-up data were obtained.Results:The primary symptoms of deep sternal wound infection-induced sepsis included dyspnea,high fever,chills,and altered state of consciousness.Laboratory test results revealed increased inflammatory markers and decreased oxygenation index.Renal and liver function injury were observed in 8 and 4 patients,respectively;18 and 12 patients demonstrated elevated D-dimer and N-terminal Pro B type natriuretic peptide levels,respectively.Of the 8 patients whose wound secretions tested positive for bacteria,Acinetobacter baumannii and Staphylococcus aureus infections were present in 6 and 2 patients,respectively.One of the 6 patients whose blood cultures tested positive for bacteria demonstrated Candida albicans infection.Fifteen patients received ventilator-assisted ventilation and 2 patients received renal replacement therapy.Of all the 21 patients,17 were cured,2 died,and 2 were discharged.Conclusion:Postmedian sternotomy sepsis attributed to a deep sternal wound infection usually results from a preexisting condition.The most prominent clinical manifestation is dyspnea,which is sometimes accompanied by the impairment of organ function.Infection prevention,proper nutrition support,and maintenance of healthy organ function are the cornerstones for successful treatment outcomes.

Investigation of the Clinical Diagnostic Significance of the T-Cell Test for Tuberculosis combined with Erythrocyte Sedimentation Test in Pulmonary Tuberculosis

Objective:To investigate the clinical diagnostic significance of peripheral blood T-cell test(T-spot test)for tuberculosis(TB)infection combined with erythrocyte sedimentation rate(ESR)in pulmonary TB.Methods:41 patients with a clinical diagnosis of TB during hospitalization from January 2020 to April 2023 in our hospital were selected as the experimental group,and 45 patients without TB(bronchopneumonia patients)were selected as the control group.The diagnostic specificity,sensitivity,and accuracy of the T-spot TB test,ESR test,and the combined test of the two were calculated respectively.Results:The sensitivity,specificity,and accuracy of the T-spot TB test combined with ESR for the diagnosis of TB in the experimental group were significantly higher than the individual results of the T-spot TB test and ESR test alone(P<0.05).Conclusion:The T-spot TB test combined with the ESR test for TB diagnosis has greater clinical value than carrying out the tests individually.

Influence of chronic HBV infection on superimposed acute hepatitis E

AIM:To investigate the influence of chronic hepatitis B virus(HBV)infection[based on the status of hepatitis B e antigen(HBeAg),HBV DNA,and cirrhosis]on superimposed acute hepatitis E.METHODS:A total of 294 patients were recruited from the Department of Infectious Diseases of the Third Affiliated Hospital,Sun Yat-sen University,from January 2003 to January 2012.The patients were classified into two groups:an HBV+hepatitis E virus(HEV)group(a group with chronic HBV infection that was superinfected with acute hepatitis E,n=118)and an HEV group(a group with acute hepatitis E,n=176).We retrospectively analyzed and compared the clinical features of the two groups.Statistical analyses were performed using theχ2test or Fisher’s exact test for categorical variables and the Student’s t test forcontinuous variables.A P value<0.05 was considered statistically significant.RESULTS:The peak values of prothrombin time,serum total bilirubin,and Model for End-Stage Liver Disease scores were significantly higher in the HBV+HEV group.More patients in the HBV+HEV group had complications(39.8%vs 16.5%,P=0.000)and developed liver failure(35.6%vs 8.5%,P=0.000).Additionally,the mortality of the HBV+HEV group was significantly higher(20.3%vs 7.4%,P=0.002).Further analysis of the HBV+HEV group showed that there were no significant differences in complication occurrence,liver failure incidence,or mortality between patients with different HBeAg and HBV DNA statuses.However,in patients with underlying cirrhosis,complication occurrence and liver failure incidence significantly increased.In total,12.7%of the patients in the HBV+HEV group received anti-HBV treatment,but this therapy failed to reduce mortality in patients who developed liver failure.CONCLUSION:The presence of underlying cirrhosis in chronic HBV infection results in more severe clinical outcomes with superimposed acute hepatitis E.AntiHBV treatment cannot improve the prognosis of liver failure caused by HBV-HEV superinfection.

Efficacy of different antibiotics in treatment of children with respiratory mycoplasma infection

BACKGROUND Respiratory infections in children are common pediatric diseases caused by pathogens that invade the respiratory system.Children are considerably susceptible to Mycoplasma pneumoniae infection.There has been widespread clinical attention on treatment strategies for this disease.AIM To analyze the clinical efficacy of different antibiotics in treating pediatric respiratory mycoplasma infections.METHODS We included 106 children with a confirmed diagnosis of respiratory mycoplasma infection who were admitted to our hospital from April 2017 to July 2019 and grouped them using a random number table.Among them,53 children each received clarithromycin or erythromycin.The clinical efficacy of both drugs was evaluated and compared.We performed the multiplex polymerase chain reaction(MP-PCR)test and determined the MP-PCR negative rate in children after the end of the treatment course.We compared the incidence of toxic and side effects,including nausea,diarrhea,and abdominal pain;further,we recorded the length of hospitalization,antipyretic time,and drug costs.Additionally,we evaluated and compared the compliance of the children during treatment.RESULTS The erythromycin group showed a significantly higher total effective rate of clinical treatment than the clarithromycin group.MP-PCR test results showed that the clarithromycin group had a significantly higher MP-PCR negative rate than the erythromycin group.Moreover,children in the clarithromycin group had shorter fever time,shorter hospital stays,and lower drug costs than those in the erythromycin group.The clarithromycin group had a significantly higher overall drug adherence rate than the erythromycin group.The incidence of toxic and side effects was significantly lower in the clarithromycin group than in the erythromycin group(P<0.05).CONCLUSION Our findings indicate that clarithromycin has various advantages over erythromycin,including higher application safety,stronger mycoplasma clearance,and higher medication compliance in children;therefore,it can be actively promoted.

Infected aortic and iliac aneurysms:Clinical manifestations in the emergency departments of two hospitals in southern Taiwan,China

BACKGROUND: Accurate diagnosis of infected aortic and iliac aneurysms is often delayed, hampering timely treatment and potentially resulting in a fatal consequence. The aim of this study was to discover useful clinical features that can help physicians to identify these patients.METHODS: We reviewed the discharge notes from two hospitals and identifi ed all patients who had a diagnosis of infected aneurysms of the thoracoabdominal aorta and iliac arteries between July 2009 and December 2013. Eighteen patients, aged from 41 to 93, were reviewed. Only 6 patients were diagnosed accurately in their fi rst visit to our ED.RESULTS: Most patients had at least one underlying illness, and it took 1 to 30(9.9±6.5) days for physicians to diagnose their infected aneurysm. Localized pain and fever were the two most commonly presented symptoms. The majority(92%) of isolated microorganisms were gram-negative bacilli, including Salmonella spp, Klebsiella pneumoniae, and Escherichia coli. Two of the 3 patients who underwent non-operative therapy died, and all of the patients who underwent a combination of medical and operative therapies survived.CONCLUSION: We suggest that physicians liberally use computed tomography scans on patients with unknown causes of pain and inflammatory processes. A combination of surgical and medical treatments is indicated for all patients with infected aortic and iliac aneurysms.

Novel mechanism of hepatobiliary system damage and immunoglobulin G4 elevation caused by Clonorchis sinensis infection

Clonorchis sinensis infection is still a major public health problem.It is estimated that more than 15 million people worldwide are infected,especially in Northeast China,Taiwan,South Korea,and North Vietnam.The detection of Clonorchis sinensis eggs in feces and bile is still the only gold standard for the diagnosis of Clonorchis sinensis infection,and new detection methods are needed to improve the detection rate.After Clonorchis sinensis invades the human body,it mainly parasitizes the hepatobiliary tract.Therefore,it is closely related to hepatobiliary diseases such as cholangitis,bile duct stones,liver fibrosis,and cholangiocarcinoma.The increase in immunoglobulin G4(IgG4)caused by Clonorchis sinensis infection is rare and there are few reports about the relevant mechanism.It may be related to the inflammatory factors interleukin(IL)-4,IL-10,and IL-13 produced by human phagocytes,T cells,B cells,and other immune cells in the process of resisting the invasion of Clonorchis sinensis.However,this finding still needs further clarification and confirmation.This article reviews the epidemiology,clinical manifestations,serology,imaging,pathogenic mechanism,and control measures of Clonorchis sinensis infection to help establish the diagnostic process for Clonorchis sinensis.We report novel mechanisms of IgG4 elevation due to Clonorchis sinensis infection to provide more experience and a theoretical basis for clinical diagnosis and treatment of this infection.

Aspirin plus Pseudoephedrine (Aspirin Complex) for the Treatment of Symptoms of Upper Respiratory Tract Infection

Upper respiratory tract infections or common colds are a multi-symptom disease which is usually symptomatically treated with fixed dose multi-active ingredient medicinal products which are commonly used as non-prescription and over the counter. However, the active ingredients combined require a particular and clinically sound justification. Analgesics and decongestant can be combined to treat simultaneously the prominent symptoms cold-related pain (e.g. headache, muscle aches and pains), fever, inflammationand nasal/sinus congestion. This overview provides a summary of the evidence supporting the combination of acetylsalicylic acid (aspirin) and pseudoephedrine available in the common cold product Aspirin? Complex.
