Project description:BACKGROUND:Asymptomatic bacteriuria in pregnancy (ASBP) is associated with adverse pregnancy outcomes such as pyelonephritis, preterm or low birth weight delivery if untreated. The aim of this study was to determine the prevalence of asymptomatic bacteriuria, the isolated bacterial agents, and their antibiotic sensitivity patterns in pregnant women attending antenatal care at Mbale Hospital. METHODS:This was a cross sectional study in which 587 pregnant women with no symptoms and signs of urinary tract infection were recruited from January to March 2019. Mid-stream clean catch urine samples were collected from the women using sterile containers. The urine samples were cultured using standard laboratory methods. The bacterial colonies were identified and antibiotic sensitivity was done using disc diffusion method. Chi squared tests and logistic regression were done to identify factors associated with asymptomatic bacteriuria. A p value < 0.05 was considered statistically significant. RESULTS:Out of the 587 pregnant women, 22 (3.75%) tested positive for asymptomatic bacteriuria. Women aged 20-24 years were less likely to have ASBP when compared to women aged less than 20 years (AOR = 0.14, 95%CI 0.02-0.95, P = 0.004). The most common isolates in descending order were E. coli (n = 13, 46.4%) and S.aureus (n = 9, 32.1%). Among the gram negative isolates, the highest sensitivity was to gentamycin (82.4%) and imipenem (82.4%). The gram positive isolates were sensitive to gentamycin (90.9%) followed by imipenem (81.8%). All the isolates were resistant to sulphamethoxazole with trimethoprim (100%). Multidrug resistance was 82.4% among gram negative isolates and 72.4% among the gram positive isolates. CONCLUSION:There was high resistance to the most commonly used antibiotics. There is need to do urine culture and sensitivity from women with ASBP so as to reduce the associated complications.

Project description:BackgroundAsymptomatic bacteriuria (ASB) is defined as the presence of bacteria in urine without having signs and symptoms. The aim of this meta-analysis was to estimate the overall prevalence of asymptomatic bacteriuria among Iranian pregnant women.MethodsMajor national and international databases were searched up to November 2015, including Scientific Information Database, MagIran, Web of Science, Medline, Scopus, Science Direct and Ovid. The checklist of the STROBE statement was used for evaluating the quality of reporting. The extracted data were analyzed and the results were reported using a random-effects model with 95% confidence interval (CI).ResultsFrom 3709 obtained studies, 20 included in the meta-analysis, which involved 15108 pregnant women. The overall prevalence of ASB was 0.13 (95% CI: 0.09, 0.17). The prevalence of ASB in the northern and southern regions of Iran was 0.13 (95% CI: 0.09, 0.18) and 0.11 (95% CI: 0.05, 0.16), respectively.ConclusionPrevalence of ASB among Iranian pregnant women is considerable. Due to the complications of ASB for pregnant women and their children, preventative planning and control of ASB among pregnant women in Iran is necessary.

Project description:BackgroundAsymptomatic bacteriuria and pyuria in healthy women often trigger inappropriate antimicrobial treatment, but there is a paucity of data on their prevalence and persistence.MethodsTo evaluate the prevalence and persistence of asymptomatic bacteriuria and pyuria in women at high risk of recurrent urinary tract infection, we conducted an observational cohort study in 104 healthy premenopausal women with a history of recurrent urinary tract infection with daily assessments of bacteriuria, pyuria, and urinary symptoms over a 3-month period.ResultsThe mean age of participants was 22 years, and 74% were white. Asymptomatic bacteriuria events (urine cultures with colony count ≥105 CFU/mL of a uropathogen on days with no symptomatic urinary tract infection diagnosed) occurred in 45 (45%) women on 159 (2.5%) of 6283 days. Asymptomatic bacteriuria events were most commonly caused by Escherichia coli, which was present on 1.4% of days, with a median duration of 1 day (range, 1-10). Pyuria occurred in 70 (78%) of 90 evaluable participants on at least 1 day and 25% of all days on which no symptomatic urinary tract infection was diagnosed. The positive predictive value of pyuria for E. coli asymptomatic bacteriuria was 4%.ConclusionsIn this population of healthy women at high risk of recurrent urinary tract infection, asymptomatic bacteriuria is uncommon and, when present, rarely lasts more than 2 days. Pyuria, on the other hand, is common but infrequently associated with bacteriuria or symptoms. These data strongly support recommendations not to screen for or treat asymptomatic bacteriuria or pyuria in healthy, nonpregnant women.

Project description:BackgroundDifferent physiologic changes that occur during pregnancy, such as Hydroureter, dilatation of the renal pelvis, glycosuria and aminoaciduria, and low urine production predispose pregnant women for ascending urinary tract infection. Globally, 2% to 15% of the pregnant women have urinary tract infection without specific symptoms. Therefore, this study aimed to estimate the prevalence of asymptomatic bacteriuria (ABU) in pregnant women in Africa.MethodsSystematic search of published studies done on PubMed, EMBASE, Web of Science, SCOPUS, PsychInfo, CINAHL, and google scholar for gray literature. All published observational studies until October 30, 2020 were included. This meta-analysis follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Quality of studies was assessed by modified Newcastle-Ottawa Scale (NOS). Meta-analysis was carried out using a random-effects method with the double arcsine transformation approach using the STATA™ Version 14 software. Trim and fill analysis was done to correct presence of significant publication bias. The study protocol is prospectively registered on PROSPERO, registration number CRD42020212601.FindingsFrom 3393 obtained studies, 48 studies from 12 African countries involving 15, 664 pregnant women included in this Meta-analysis. The overall pooled prevalence of asymptomatic bacteriuria among pregnant women in Africa after correction for publication bias by trim and fill analysis was found to be 11.1% (95% CI: 7.8, 14.4). The most common bacterial isolates involved in the etiology of ABU was Escherichia coli with pooled prevalence 33.4% (95% CI: 27.3 - 39.4).InterpretationAsymptomatic bacteriuria is substantial among pregnant women in Africa. Therefore, all pregnant women should be tested for the presence of asymptomatic bacteriuria. A screening program must be based not only on the incidence but also on a cost-efficacy evaluation and a microbiological evaluation.FundingThere was no funding source for this study.

Project description:Background:Asymptomatic bacteriuria is one of the major risk factors for the development of urinary tract infections during pregnancy which accounts for about 70% of the cases. However, there is no guideline which recommends routine screening of pregnant women for asymptomatic bacteriuria in most of developing countries including Ethiopia. Thus, the aim of this study was to determine the magnitude, associated factors, and antimicrobial susceptibility pattern of asymptomatic bacteriuria among pregnant women. Methods:A cross-sectional study was conducted from March to April 2019. Data were collected through face-to-face interview and analyzed using Statistical Package for Social Science version 22. A test of association was performed using logistic regression and P value less than 0.05 was considered statistically significant. Results:The overall prevalence of asymptomatic bacteriuria was 19.9%. Direction of wiping after genital wash, postcoital urination, and catheterization were factors significantly associated with asymptomatic bacteriuria. Most of the isolated Gram positive were highly sensitive to Ceftriaxone (90.9%). Coagulase-negative staphylococci showed higher sensitivity to Augmentin (75.0) and Ceftriaxone (87.5%), whereas they showed resistance to Clindamycin (68.7%) and Ampicillin (62.5%). Gram-negative bacteria isolates showed higher sensitivity to Ceftriaxone (88.2%), Gentamycin (67.5%), and Augmentin (64.7%), while they showed resistance to Ampicillin (70.5%) and Clindamycin (50.0%). Conclusion:The overall prevalence of asymptomatic bacteriuria among pregnant women in this study was high. Direction of wiping after genital wash, catheterization, and postcoital urination increases the odds of asymptomatic bacteriuria. Therefore, health education on the predisposing factors is strongly recommended.

Project description:Introduction Asymptomatic bacteriuria (ASB) is the presence of bacteria in significant quantity in the absence of signs and symptoms of urinary tract infection (UTI). ASB, if it occurs during pregnancy, can cause serious complications both among fetus and pregnant women. Objective The aim of this study was to determine the prevalence of ASB, its associated factors, and antimicrobial susceptibility profile of bacterial isolates among pregnant women. Methods A cross-sectional study was conducted from July to September 2019 among 290 pregnant women at Saint Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia. Clean-catch midstream urine specimens were collected using sterile containers and cultured on MacConkey agar and sheep blood agar to isolate bacteria. Socio-demographic and obstetric data were collected using a structured questionnaire. Data were analyzed by SPSS version 22. The association between ASB and risk factors was assessed using logistic regressions. A p-value??0.05 was considered as a cut point to determine the significant association. Results From 290 study participants, 16.9% with 95 CI [13.1, 21.5] were positive for ASB. The predominant bacteria were Escherichia coli (43%) and Staphylococcus aureus (20%). Majority of E. coli (91.0%) were susceptible to nitrofurantoin and gentamycin; most of them were resistant to amoxicillin (86.4%) and cotrimoxazole (77.7%). The proportion of multi-drug resistance (MDR) isolates was 57.1%. Previous infection with UTI, previous history of catheterization, and natural abortion were significantly associated with ASB. Conclusion In the study area, ASB is prevalent in the study area indicating the importance of screening of ASB and possible treatment to prevent its consequences.

Project description:Aim:The study was conducted to assess the prevalence of high-risk pregnancy (HRP) cases among pregnant women visiting the Prabhakar Kore Hospital (PKH) at Belagavi, Karnataka for antenatal care (ANC) and determination of the level of risk in the identified cases. Materials & Methods:Data were collected as a part of a screening procedure of a nutrition supplement clinical trial on pregnant women [Study title: Maternal DHA Supplementation and offspring Neurodevelopment in India (DHANI)]. ANC case records including detailed notes on medical and obstetric history, physical examination, laboratory investigations of pregnant women with ? 20 weeks of gestational age were screened for known risk factors. Results:A total of 11,686 new cases were registered for ANC between June 2016 through August 2017. Of these, 3379 (<20 weeks gestation) were screened out of 428 pregnant women, 12.6% pregnant women were found to be at risk, 40.2% (n=172) fell in the high-risk category. Most commonly reported risk factors were thyroid disorders (27.3%, hypothyroidism 17.3%; hyperthyroidism 10%), gestational diabetes (16.1%), bad obstetric history (12.6%) and anaemia (10.7%). Conclusion:Early identification of these at-risk mothers through a simple, practical, reliable and customized risk scoring schedule can ensure interventions either to control the risk causing factor or delivery of timely and appropriate care as and when needed. Clinical Significance:Considering the disproportionate burden that high risk pregnancies pose on higher mortality rates and compromised quality of life for the cases which survive, early identification of these high risk cases (12.6% identified in this study) can have a significant impact on maternal and child health. The population negatively affected by at-risk pregnancies is only expected to increase in the near future in light of the rising trend of its known risk factors such as high blood pressure, diabetes, or being HIV-positive.

Project description:Many studies have been undertaken in Nigeria on maxillofacial trauma. However, only a few have considered both the skeletal and soft tissue injuries (in general) involving all the aspects of the maxillofacial region or considered other etiological sources of trauma apart from road traffic crashes. Fewer still have reviewed the outcome of management of facial injuries in our low-resource environment. This study sets out to examine the recent trends in both the clinical and epidemiological patterns of all facial injuries from all causes seen in a low-resource practice of a developing country. It also assessed the in-hospital treatment outcomes, and the levels of the patients' satisfaction with treatment received in this setting. Over a 12-month period, the clinical records of consecutive patients who were evaluated and treated for maxillofacial injuries in our unit were prospectively acquired, entered into predesigned forms and subsequently analyzed. There were 259 patients (79.5% males) during the study period. The mean age was 32.21( ± 16.588) years. Overall, motor bike crashes, 42.1%, were the commonest source of these traumas; and armed robbery was the commonest form (69.0%) of assault. Mandibular fractures were the commonest maxillofacial fractures (37.8%) whereas head injury had the highest frequency among the associated injuries (71.4%). Closed reduction and immobilization was deployed in 88.0% of those who had treatment and majority was satisfied with the esthetic outcome of the treatment received. Mean length of hospital stay was 12.6 ( ± 4.423) days. Maxillofacial trauma poses a significant socioeconomic burden on affected individuals in this study population. This is made worse by the presence of associated injuries in the other body systems. More local studies on the outcome of management of maxillofacial trauma will improve the available literature in this region.

Project description:BackgroundAsymptomatic bacteriuria is a bacterial infection of the urine without any of the typical symptoms that are associated with a urinary infection, and occurs in 2% to 15% of pregnancies. If left untreated, up to 30% of mothers will develop acute pyelonephritis. Asymptomatic bacteriuria has been associated with low birthweight and preterm birth. This is an update of a review last published in 2015.ObjectivesTo assess the effect of antibiotic treatment for asymptomatic bacteriuria on the development of pyelonephritis and the risk of low birthweight and preterm birth.Search methodsFor this update, we searched the Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) on 4 November 2018, and reference lists of retrieved studies.Selection criteriaRandomised controlled trials (RCT) comparing antibiotic treatment with placebo or no treatment in pregnant women with asymptomatic bacteriuria found on antenatal screening. Trials using a cluster-RCT design and quasi-RCTs were eligible for inclusion, as were trials published in abstract or letter form, but cross-over studies were not.Data collection and analysisTwo review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked for accuracy. We assessed the quality of the evidence using the GRADE approach.Main resultsWe included 15 studies, involving over 2000 women. Antibiotic treatment compared with placebo or no treatment may reduce the incidence of pyelonephritis (average risk ratio (RR) 0.24, 95% confidence interval (CI) 0.13 to 0.41; 12 studies, 2017 women; low-certainty evidence). Antibiotic treatment may be associated with a reduction in the incidence of preterm birth (RR 0.34, 95% CI 0.13 to 0.88; 3 studies, 327 women; low-certainty evidence), and low birthweight babies (average RR 0.64, 95% CI 0.45 to 0.93; 6 studies, 1437 babies; low-certainty evidence). There may be a reduction in persistent bacteriuria at the time of delivery (average RR 0.30, 95% CI 0.18 to 0.53; 4 studies; 596 women), but the results were inconclusive for serious adverse neonatal outcomes (average RR 0.64, 95% CI 0.23 to 1.79, 3 studies; 549 babies). There were very limited data on which to estimate the effect of antibiotics on other infant outcomes, and maternal adverse effects were rarely described. Overall, we judged only one trial at low risk of bias across all domains; the other 14 studies were assessed as high or unclear risk of bias. Many studies lacked an adequate description of methods, and we could only judge the risk of bias as unclear, but in most studies, we assessed at least one domain at high risk of bias. We assessed the quality of the evidence for the three primary outcomes with GRADE software, and found low-certainty evidence for pyelonephritis, preterm birth, and birthweight less than 2500 g.Authors' conclusionsAntibiotic treatment may be effective in reducing the risk of pyelonephritis in pregnancy, but our confidence in the effect estimate is limited given the low certainty of the evidence. There may be a reduction in preterm birth and low birthweight with antibiotic treatment, consistent with theories about the role of infection in adverse pregnancy outcomes, but again, the confidence in the effect is limited given the low certainty of the evidence. Research implications identified in this review include the need for an up-to-date cost-effectiveness evaluation of diagnostic algorithms, and more evidence to learn whether there is a low-risk group of women who are unlikely to benefit from treatment of asymptomatic bacteriuria.

Project description:BACKGROUND:The diagnosis of urinary tract infections (UTIs) in institutionalized older adults is often based on vague symptoms and a positive culture. The high prevalence of asymptomatic bacteriuria (ABU), which cannot be easily discriminated from an acute infection in this population, is frequently neglected, leading to a vast over-prescription of antibiotics. This study aimed to identify subpopulations predisposed to transient or long-term ABU. METHODS:Residents in a long-term care facility were screened for ABU. Mid-stream urine samples were collected during two sampling rounds, separated by 10 weeks, each consisting of an initial and a confirmative follow-up sample. RESULTS:ABU occurred in approximately 40% of the participants and was mostly caused by Escherichia coli. Long-term ABU (> 3 months) was found in 30% of the subjects. The frailest women with urinary incontinence and dementia had drastically increased rates of ABU and especially long-term ABU. ABU was best predicted by a scale describing the functional independence of older adults. CONCLUSIONS:Institutionalized women with incontinence have ABU prevalence rates of about 80% and are often persistent carriers. Such prevalence rates should be considered in clinical decision making as they devalue the meaning of a positive urine culture as a criterion to diagnose UTIs. Diagnostic strategies are urgently needed to avoid antibiotic overuse and to identify patients at risk to develop upper UTI.
