The Bishop score (BS) is the gold standard method to assess cervical status, but it is not flawless, leading to unnecessary interventions. Transperineal ultrasound measurements have been compared with the BS in predicting successful IOL. Yet the results are inconsistent. Aim: This study aimed to compare transperineal ultrasound measurements and a simplified BS in predicting IOL outcomes at Ahmadu Bello University Teaching Hospital (ABUTH) Zaria. Settings and Design: This was a cross-sectional comparative observational study conducted at the labor wards of ABUTH. Materials and Methods: It was conducted among women for IOL at 37–42 weeks between June 2019 and February 2020. Ninety-Seven women were recruited. Each woman, had a transperineal ultrasound cervical length (TPUS-CL) and fetal head perineum distance (FHPD) measured. This was followed by a simplified BS assessment. Statistical Analysis Used: Relevant Data obtained was entered and analyzed using SPSS version 23. The significance level was considered at P < 0.05. Results: The diagnostic accuracy of TPUS-CL (area under the curve (AUC) =0.604, P = 0.084) was better than the simplified BS (AUC = 0.551, P = 0.402). FHPD (P = 0.067, CI = 0.983–1.661) was superior to fetal station (P = 0.832, CI = 0.599–1.890) in predicting the outcome of IOL. The favorable cut-off values for TPUS-CL, FHPD, and BS in our study were ≤ 3 cm, ≤5 cm, and 5 respectively. It demonstrated that TPUS-CL (P = 0.005, AUC = O.750) and FHPD (P = 0.017, AUC = 0.711) are better than simplified BS in predicting success among Primigravidas. Conclusion: TPUS-CL and FHPD measurements are better than the simplified BS in predicting IOL outcome in primigravidae.","PeriodicalId":19224,"journal":{"name":"Nigerian Journal of Basic and Clinical Sciences","volume":"37 1","pages":"171 - 176"},"PeriodicalIF":0.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139365000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: This study aimed to find the magnitude, distribution, socio-demographic, and other factors associated with hemodialysis in Jigawa state, Northwest Nigeria. Materials and Methods: It was a retrospective multicenter analysis of secondary data from hemodialysis centers of the randomly selected public hospitals in northwest Nigeria. Statistical Analysis: Data were analyzed using IBM SPSS Statistics for Windows, version 22.0, with statistical significance set at P ≤ 0.05. Results: A total of 1,329 patients were enrolled for dialysis in Kano and Jigawa states, between 2019 and 2022, out of which more than one-third (509, 38.3%) were from Jigawa state. Dutse, Jahun, Gumel, and Hadejia local government areas (LGAs) of Jigawa state had 86 (16.8%), 64 (12.6%), 48 (9.4%), and 44 (8.6%) respectively. The respondent's ages ranged from 1 − 100 years with a median age of 48 (interquartile range [IQR] = 31, 60) years. Chronic kidney disease (CKD) was found among 403 (79.2%) patients, acute on chronic kidney disease (AOCCKD) in 87 (17.1%) patients, and acute kidney injury (AKI) in 19 (3.7%) patients. The major risk factors identified were hypertension, diabetes, and chronic glomerulonephritis (CGN) among 329 (64.6%), 69 (13.6%), and 66 (13.0%) patients, respectively. Hypertension was a significantly higher risk factor among patients from Jigawa state compared with other states (46.8%, P < 0.001), hypertensives from Jigawa state were twice more likely to develop kidney disease requiring hemodialysis (adjusted odds ratio [aOR] = 2.2, 95% confidence interval [CI] = 1.7–2.8) compared with non-hypertensive etiologies. Conclusion: The burden of kidney diseases requiring hemodialysis in Jigawa state is high, with hypertension and diabetes being the major risk factors for hemodialysis. The government and other stakeholders should develop strategies for early identification and proper management of the risk factors.","PeriodicalId":19224,"journal":{"name":"Nigerian Journal of Basic and Clinical Sciences","volume":"7 1","pages":"118 - 124"},"PeriodicalIF":0.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139365340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: To determine the incidence, timing of diagnosis, and possible risk factors for wound infection in low-risk cesarean sections. Settings and Design: A prospective cross-sectional study conducted among consenting women undergoing low-risk cesarean sections, defined as the absence of established risk factors for post-operative wound infection. Materials and Methods: Participants' sociodemographic and obstetric characteristics were documented in a structured proforma. The primary outcome measure was the incidence and timing of wound infection. Secondary outcome measures were the incidences of endometritis and febrile morbidity. The data were analyzed using SPSS version 21 and Windows WINPEPI. Results: The incidence of wound infection was 11.2% (19); endometritis—20.6% (35); febrile morbidity—4.1% (7).

Premarital counseling (PMC) programs to reduce the burden of hemoglobinopathies have been successfully implemented in Muslim predominant countries with similar religious and cultural practices to northern Nigeria. Religious leaders have a significant role to play in the success of PMC in northern Nigeria. Aims: To assess the knowledge and perception of premarital genetic counseling for sickle cell disease (SCD) among religious leaders in a culturally and religiously sensitive environment. Settings and Design: A cross-sectional (pre and post) study was conducted during the premarital screening workshop for SCD on July 20th, 2019, at Bayero University Kano, northwest Nigeria. Materials and Methods: Convenient sampling method was used to identify and invite 126 Islamic clerics through the CICID (Centre for Islamic Civilization and Interfaith Dialogue) at Bayero University Kano, to a premarital screening workshop for SCD. Self-administered semi-structured pre-and posttest questionnaires were used to collect data from the participants. Aminu Kano Teaching Hospital Human Health Research and Ethics Committee approved this study. Statistical Analysis Used: Statistical analyses were performed with R version 4.0.2. The data were summarized using descriptive statistics and presented as mean ± standard deviation (SD), median and interquartile range (IQR), and percentages as appropriate. Wilcoxon test for score comparison of pre-and posttest was used with a significance level of 0.05. Results: A total of 97 religious' leaders with a mean age ± SD of 44.7 ± 12.7 completed both pre-and posttests. The male-to-female ratio was 5:1.
