IntroductionIt is estimated that about 11–35% of pregnant women are colonized with Group B streptococcus. Intrapartum antibiotic prophylaxis (IAP) is the primary intervention to decrease the risk of infecting babies born to GBS colonized mothers.MethodsA total of 5,996 pregnant women, who received the Taiwanese universal GBS screening program from 2012 to 2020, were included in this study that investigated GBS colonization, antimicrobial resistance rates and their neonatal incidence of invasive GBS infection.ResultsThe average GBS colonization rate was 18.5%. Older age groups had higher colonization rates than younger age groups. Compared to Taiwanese, immigrant women from Indonesia had a greater positive rate. GBS isolated from Vietnamese women had significant greater resistance to clindamycin relative to Taiwanese women. Rates of resistance to erythromycin increase from 35.5% to 45.5% over the 9 years of measurements. The incidence of invasive GBS disease was about 0.6/1,000 (4/6,204) live births during the study.ConclusionsAlthough relatively low incidence of invasive GBS diseases was observed after implementation of IAP, the colonization of GBS remains high and antimicrobial resistance of GBS is increasing. An effective GBS vaccine holds promise to be a solution for these issues.  相似文献

BackgroundPregnancy is a key step for human''s reproduction and continuity of generation. Pregnant women are among at risk groups for the infection of soil-transmitted helminths (STHs). STHs are highly prevalent in low- and middle-income countries due to the deprived environmental sanitation and personal hygiene. Eating soil (geophagia) is also commonly practiced by pregnant women, particularly in developing countries. The aim of this study was to determine the prevalence of STHs and geophagia, and to assess associated factors among pregnant women in Jimma, Southwest Ethiopia.MethodsA cross sectional study was conducted among 407 pregnant women attending antenatal care (ANC) at different health facilities located in Jimma Town. Data related to sociodemographic and geophagia practice was collected using a structured questionnaire and STH infections status was determined by using McMaster technique.ResultsA total of 407 pregnant women were included in this study. The overall prevalence of any STHs was 19.7% (80/407). Ascaris lumbricoides was the most prevalent 45(56.2%), followed by Trichuris trichiura 19(23.8%) and hookworms 12(15%). There were 4(5%) of double infection with A. lumbricoides and T. trichiura. Overall, 71 (17.4%) of the pregnant women responded to practice geophagia. STHs infection was significantly higher among geophagic pregnant women (p<0.01) and pregnant women who practiced geophagia were 3 times more likely (OR 2.9, 95% CI 1.3–4.2) to have the STHs compared to non-geophagic. Out of those who claimed soil eating habits, 59.1% preferred reddish soil type. Geophagia practice was significantly higher during the third trimester as compared to first and second (p<0.05).ConclusionGeophagia is a risky behavior and this study showed a significant association of geophagia practice with STH infections, although the causal relation could not be established.  相似文献

Past studies have mainly investigated the association of serotype-specific capsular IgG in the mother and risk reduction of invasive Group B Streptococcus (GBS) in their young infants. The efficiency of transplacental transfer of IgG could be affected by multiple maternal factors. Hence, investigation of infant serum GBS anti-capsular IgG and risk reduction for invasive GBS disease may be more robust and generalizable. In a matched case-control study, infant serum serotype-specific capsular polysaccharide Ia and III IgG concentrations were analyzed in infants with invasive GBS cases and healthy controls born to women with recto-vaginal colonization by the homotypic serotype. Using Bayesian modeling, an antibody concentration of 2.5 µg/mL and 1 µg/mL predicted a 90% reduced risk of invasive disease for serotype Ia and III, respectively. These data contribute to the possible licensure of a GBS polysaccharide-protein conjugate vaccine, targeted at pregnant women, based on serological correlates of protection against invasive GBS disease.  相似文献

The objective of this article is to determine whether racial/ethnic disparities exist in screening for group B streptococcus (GBS) colonization among pregnant women. A retrospective cohort study of deliveries at a single institution was conducted. The primary outcome was the availability of GBS culture data at the time of delivery; the primary predictor was maternal race/ethnicity. Analyses were stratified by the time periods before and after the CDC recommendations for universal screening for GBS. Among 16,333 deliveries, 60.4% of the population was screened for GBS but screening rates varied markedly by year of delivery. Black women had a lower odds of having available GBS data (AOR 0.81 [0.69, 0.95]) but this disparity was limited to the period of time before universal screening was recommended. Prior to the recommendation for universal screening for GBS, racial/ethnic disparities existed in rates of screening among pregnant women delivering at term. These differences were reduced after 2002, suggesting that uniform policies regarding obstetrical care may be effective in eliminating disparities in obstetrical care and outcomes.  相似文献

In the United States, group B streptococcus (GBS) is the leading cause of serious bacterial infections in newborns. In 1996, consensus guidelines for use of intrapartum antibiotic prophylaxis (IAP) to prevent perinatal GBS disease recommended either of two methods for identifying candidates for chemoprophylaxis: 1) late prenatal culture-based screening for GBS colonization or 2) monitoring of women intrapartum for particular risk factors associated with early-onset GBS disease. Evidence that culture-based screening was substantially more effective than the risk-based approach led to revised guidelines in 2002 recommending late prenatal GBS screening for all pregnant women. Although methods for isolation and identification of GBS from prenatal specimens remained the same as those recommended in 1996, the 2002 guidelines recommended that laboratories perform antimicrobial susceptibility testing on prenatal GBS isolates from women at high risk for penicillin anaphylaxis and clarified that laboratories should report the presence of any GBS in urine specimens from pregnant women. To assess laboratory adherence to recommendations in the 2002 guidelines, CDC's Active Bacterial Core surveillance (ABCs)/Emerging Infections Program Network surveyed clinical laboratories about prenatal culture-processing practices in 2003. This report summarizes the results of that survey, which indicated that, although adherence to GBS isolation procedures was high, opportunities exist to improve implementation of recommendations related to antimicrobial susceptibility testing and GBS bacteriuria.  相似文献

BackgroundAbnormal blood glucose level is one of the most frequently encountered problems in children with severe illnesses. However, its magnitude and outcome have rarely been determined in Ethiopia. We aimed to determine the magnitude, associated factors and outcome of dysglycemia in critically ill children admitted to Jimma Medical Center.MethodsProspective longitudinal study was conducted on children aged 28 days to 14 years admitted with critical illnesses at the different units of the Department of Pediatrics and Child Health of Jimma Medical Center, Southwest Ethiopia, from June to August 2019. Data were collected by trained medical personnel using structured questionnaire and analyzed using Statistical Package for Social Sciences (SPSS) windows version 20.0. Dysglycemia was considered whenever the child had a random blood sugar >150mg/dl or <45mg/dl.ResultDysglycemia was seen at admission in 139/481, 28.9% children; 24 (5.0%) had hypoglycemia whereas 115 (23.9%) had hyperglycemia. The factors associated with dysglycemia at admission were severe acute malnutrition (p=002, AOR=3.09, CI=1.18,7.77), impaired mental status (p=0.003, AOR=4.63, CI=1.68, 12.71), place of residence (p=0.01, AOR=1.85, CI=1.15–2.96) and presence of diarrhea on date of admission. Among the children who had dysglycemia at admission, 16/139, 11.5% died.ConclusionDysglycemia is a common problem in critically ill children in the setting. Blood glucose level should be determined for all critically ill children, and routine empirical administration of dextrose should be minimized since most of the children with dysglycemia had hyperglycemia than hypoglycemia.  相似文献

ABSTRACT

Introduction: About 22% of pregnant women are anemic in Ethiopia, but there is a large variation across the country. Hence, the aim of this study identifies the prevalence of anemia and associated factors among pregnant women attending prenatal appointments in Dembia District, northwest Ethiopia.Methods and materials: A facility-based, cross-sectional study was conducted among 713 pregnant women. A multi-stage, stratified sampling technique was used to select the study participants. A structured and pretested questionnaire, laboratory data, and chart review were used to collect data. Bivariate and multivariate logistic regression analyses were used to identify factors associated with anemia in pregnant women.Results: Prevalence of anemia was 32.4% with a majority of these having moderate anemia. Type of health center being rural/urban health center, water sources, days since fasting, 4 weeks of iron supplementation, craving unusual foods, mid-upper arm circumference scores, and decision power were significant predictors of anemia.Conclusion: The present study suggests anemia among pregnant women attending prenatal in Dembia district was high. Working to enhance adherence to iron supplementation and partner involvement for joint decision-making is recommended to avert prenatal anemia. Health-care providers and programmers are advised to pay special attention to rural and fasting pregnant mothers.

Background  

Group B streptococcus (GBS), which asymptomatically colonises the vaginal and rectal areas of women, is the leading cause of septicemia, meningitis and pneumonia in neonates. In Tanzania no studies have been done on GBS colonisation of pregnant women and neonates. This study was conducted in Dar es Salaam, Tanzania to determine the prevalence of GBS colonisation among pregnant women, the neonatal colonisation rate and the antimicrobial susceptibility, thus providing essential information to formulate a policy for treatment and prevention regarding perinatal GBS diseases.  相似文献

BackgroundSuicide is a serious cause of mortality worldwide and the single most common cause of death in the prison population. Studies on suicidal ideation and attempt among prison people in Ethiopia are limited. Therefore, the objective of this study was to assess the prevalence and associated factors of suicidal ideation and attempt among prisoners in Debre Markos Correctional Center, northwest, Ethiopia, 2019.MethodAn institution-based cross-sectional study was conducted using the simple random sampling technique; a total of 640 participants was recruited. Suicidal ideation and attempts were assessed using the suicidality module of the World Mental Health (WMH) survey initiative version of the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI).ResultsThe prevalence of suicidal ideation and attempt were 21.9% and 13.1% with 95% CI (18.40, 25.20) and (10.60, 15.80) respectively. The study revealed that female sex (AOR=2.60, 95%CI: 1.39, 8.20) and family history of mental illness (AOR=2.08, 95%CI: 1.11, 3.90) were significantly associated with both suicidal ideation and attempt. Whereas divorced/widowed (AOR=3.67, 95%CI: 2.05, 6.58), common mental disorder (AOR=1.98, 95%CI: 1.25, 3.16) and poor social support (AOR=2.68, 95%CI: 1.42, 5.06) were statistically associated with suicidal ideation, and previous incarceration (AOR=2.38, 95%CI: 1.20, 5.16) was significantly associated with a suicide attempt.ConclusionThe result shows that the prevalence of suicidal ideation and attempt were serious problems among prisoners. As a result, inmate people need greater attention and interventions for suicidal behaviors.  相似文献

BackgroundMedical students often experience chronic stress. Self-esteem is one of the most important factors in the process of psychosocial growth and has remarkable effect on thoughts, feelings, values, and goals. The aim of this study was to assess the prevalence and associated factors of low self-esteem (LSE) and mental distress among Medical Students of Jimma University.MethodThis cross-sectional study was conducted in Jimma University from June to July, 2018. Self-esteem was measured with Rosenberg self-esteem scale. Self-administered Short form with General Health Questionnaire was used to assess presence of mental distress.ResultOut of 422 students enrolled to the study, 279 (66.1%) were male, and 413 (97.9 %) were 18 to 25 years of age. The prevalence of LSE and mental distress were 19.0%, and 19.7 %, respectively. Students who had LSE had 5 times higher risk of having mental distress, AOR= 5.1 (95% CI, 2.9–8.9). Moreover, female students had higher risk of developing mental distress (AOR=1.9, 95% CI, 1.1–3.3). Students who had poor social support were 4.3 times at higher risk of developing LSE, AOR=4.3 (95% CI, 1.9–9.8). Those who reported to have poor academic performance were also more likely to have LSE AOR= 3.7 (95% CI, 1.3–10.0).ConclusionOne in five medical students had LSE and it is strongly associated with metal distress. Female students were at higher risk of mental distress. Preventive, curative and rehabilitative mental health services should be available for medical students with particular attention to those with poor social support.  相似文献

Objective

Group B Streptococcus (GBS) causes significant infant morbidity and mortality. Promising GBS vaccines are currently in clinical trials. Because GBS vaccines would be the first to specifically target pregnant women, we sought to assess acceptability of a hypothetical GBS vaccine.

Study design

We performed an internet survey among currently pregnant or recently delivered women receiving care at one of 9 Ob/Gyn practices in Colorado. Vaccine acceptability was assessed using questions based on constructs from the Health Belief Model. Multivariable analyses assessed the characteristics associated with GBS vaccine acceptability during the current/recent pregnancy.

Results

The response rate was 50% (n = 231). While 78% agreed that a GBS vaccine would be a good way to protect newborns, 90% and 83% agreed, respectively, that they worried generally about the safety and effectiveness of new vaccines. Moreover, 39% believed it is generally dangerous for pregnant women to get vaccines. Seventy nine percent ‘definitely’ or ‘probably’ would have gotten a GBS vaccine in their most recent pregnancy if available. The most influential factors associated with this outcome were a strong belief in the vaccine's benefits (adjusted odds ratio [AOR] 6.37, 95% confidence interval [CI] 2.01–20.16), and low perceived barriers to vaccination (AOR 0.11, 95% CI (0.03–0.37)).

Conclusion

A GBS vaccine may be acceptable to pregnant women but would benefit from strong provider support and education about the risks and consequences of GBS infection and the benefits to vaccination.  相似文献

BackgroundThe emergence and spread of antimicrobial resistance (AMR) among uropathogens is increasing, especially in resource limited settings due to a number of reasons. The production of Extended Spectrum β-Lactamase (ESBL) by some strains of E. coli and methicillin resistant Staphylococcus species, limits the choice of antimicrobials in the treatment of urinary tract infection (UTI) globally. However, little is known about the type of uropathogenes and their current AMR profile among pregnant women in Hargeisa, Somaliland.MethodsClean-catch mid-stream urine samples were collected and processed for bacteriological culture and antimicrobial sensitivity testing (AST). Ceftazidime (30µg) and Cefotaxime (30µg) disks were used for ESBL screening as per CLSI guideline and each ESBL screening positive isolate were phenotypically confirmed by a combination disk test.ResultsAmong 376 study participants, 79 (21.0%) had significant bacteriuria (SBU). Majority at 58(73.4%) of the isolates were Gram-negative. The most predominant isolate was E.coli, 36(45.6%) followed by K. pneumonea 16(20.3%) and S. aureus at 9(11.4 %). The proportion of ESBL producing isolates was 25(32.9%). Gram-negatives showed high level resistance to ampicillin, amoxicillin, cefotaxime, and cephalexin at 87%, 85%, 57%, and 52%, respectively. Previous history of UTI, monthly income, educational status and having dysuria were significantly associated with SBU (p<0.05).ConclusionRelatively high prevalence of uropathogens and an increased level of drug resistance were documented. Therefore, continued surveillance on the type of uropathogens and their AMR pattern is needed to ensure appropriate recommendations for the rational empirical treatment of UTI and for policy input.  相似文献

BackgroundMaternal immunisation is an important strategy to reduce neonatal mortality and morbidity. New maternal vaccines such as Respiratory Syncytial Virus (RSV) and Group B streptococcus (GBS) are in development and/or clinical trials. However, little is known about pregnant women’s knowledge about these diseases.MethodsWomen attending antenatal clinics in Melbourne, Australia were invited to complete a questionnaire collecting demographic information, past vaccination history, understanding of risk of GBS and RSV disease in pregnancy and likelihood to accept these theoretical vaccines in the future.Findings495 women (48% born outside of Australia, from 48 different countries) completed the questionnaire. A large number of women had never heard of GBS (63%) or RSV (83%). Women over 35 years, born in Australia and women who had more than one child were more likely to have heard of GBS or RSV (p < 0.001). Women who had received influenza or pertussis vaccine in pregnancy were more likely to accept a RSV or GBS vaccine (p < 0.001).ConclusionsThis study has shown that knowledge of GBS and RSV is poor. However, when provided with information about the two diseases, acceptance of a hypothetical vaccine for both diseases was high. This study highlights the enormous amount of work that needs to be done in educating pregnant women about the seriousness of these two diseases if a future vaccine is ever to be accepted and high coverage achieved among the target population.  相似文献

BackgroundThe prevalence of diabetes and its associated complications rising in Ethiopia ranged from 2.0%–6.5%, the primary cause of morbidity and mortality with consequential economic impact. This study aimed to assess the prevalence and risk factors of dyslipidemia among diabetes follow-up patients.MethodsInstitution-based cross-sectional study was conducted at Debre Berhan Referral Hospital from January to March 2020 in 347 Adult type 2 diabetes follow-up patients using a convenient sampling technique. Data were collected by interviews and entered using Epi-data 4.2 and analyzed using SPSS version 25. Factors having a p-value < 0.25 in the bi-variable logistic regression model were entered into a multivariable logistic regression model. Statistical Significance was declared at a p-value ≤ of 0.05.ResultsThe prevalence of dyslipidemia among type 2 diabetes patients in this study was 59 %. Significantly associated variables were being female [AOR 2.6 (95% CI 1.2–3.2), P = 0.011], smoking history [AOR 4.1 (95% CI 2–6.8), P = 0.001], Being overweight [AOR 3.5 (95% CI 1.6–7.8), P = 0.002], Being obese [AOR 4.8 (95% CI 1.7–13), P = 0.002].ConclusionPrevalence of dyslipidemia was high among diabetic patients, which accounts for 59%. Being female, smoking history, being overweight, and being obese were determinants of dyslipidemia. Patients with poor glycemic control need additional lipid-lowering therapies to prevent secondary Atherosclerotic vascular complications.  相似文献
