OBJECTIVE: The aim of the present study was to identify the risk factors for severe maternal outcomes (SMO) of women with suspected or confirmed infections using the data from the WHO global maternal sepsis study (GLOSS).
METHODS: We conducted a secondary analysis of the GLOSS cohort study, which involved pregnant or recently pregnant women with suspected or confirmed infection around 713 health facilities in 52 low- and middle-income countries, and high-income countries. A nested case-control study was conducted within the GLOSS cohort. Cases included infection-related maternal deaths or near misses, while controls represented non-SMO. Logistic mixed models, adjusting for country variations, were employed. Using univariate analysis, we calculated crude odds ratios (crude OR) and their 95% confidence interval (95% CI). Variables were identified with less than 16% missing data, and P values less than 0.20 were used to perform the multivariate logistic model multilevel.
RESULTS: A total of 2558 women were included in the analysis. As for the cases, 134 patients were found in the pregnant in labor or not in labor group and 246 patients in the postpartum or postabortion group. Pregnant women with prior childbirths faced a 64% increased risk of SMO. Ante- or intrapartum hemorrhage increased risk by 4.45 times, while trauma during pregnancy increased it by 4.81 times. Pre-existing medical conditions elevated risk five-fold, while hospital-acquired infections increased it by 53%. Secondary infections raised risk six-fold. Postpartum/postabortion women with prior childbirths had a 45% elevated risk, and pre-existing medical conditions raised it by 2.84 times. Hospital-acquired infections increased risk by 93%. Postpartum hemorrhage increased risk approximately five-fold, while abortion-related bleeding doubled it. Previous cesarean, abortion, and stillbirth also elevated risk.
CONCLUSIONS: Key risk factors for SMO include prior childbirths, hemorrhage, trauma, pre-existing conditions, and hospital-acquired or secondary infections. Implementing effective alert systems and targeted interventions is essential to mitigate these risks and improve maternal health outcomes, especially in resource-limited settings.

Pre-eclampsia and eclampsia are the second leading causes of maternal mortality and morbidity. It also results in high perinatal mortality and morbidity. Since eclampsia is preceded by preeclampsia and shows the progression of the disease, they share the same pathogenesis and determining factors. The purpose of this study was to determine determinants of preeclampsia, since it is essential for its prevention and/or its associated consequences. An unmatched case-control study was conducted from September 1-30, 2023 among women who gave birth from June 1, 2020, to August 31, 2023, at Hiwot Fana Comprehensive Specialized University Hospital. Women who had preeclampsia were considered cases, while those without were controls. The sample size was calculated using EPI Info version 7 for a case-control study using the following assumptions: 95% confidence interval, power of 80%, case-to-control ratio of 1:2, and 5% non-response rate were 305. Data was collected using Google Form, and analyzed using SPSS version 26. Variables that had a p-value of < 0.05 on multivariable logistic regression were considered statistically significant, and their association was explained using an odds ratio at a 95% confidence interval. A total of 300 women (100 cases and 200 controls) with a mean age of 24.4 years were included in the study. Rural residence (AOR 2.04, 95% CI 1.10-3.76), age less than 20 years (AOR 3.04, 95% CI 1.58-5.85), history of hypertensive disorders of pregnancy (AOR 5.52, 95% CI 1.76-17.33), and no antenatal care (AOR 2.38, 95% CI 1.19-4.75) were found to be the determinants of preeclampsia. We found that living in a rural areas, previous history of preeclampsia, no antenatal care, and < 20 years of age were significantly associated with preeclampsia. In addition to previous preeclampsia, younger and rural resident pregnant women should be given attention in preeclampsia screening and prevention.

BACKGROUND: The severity and treatment response of acne, melasma, and rosacea may be influenced by various currently unclear internal and external factors. This study aimed to provide evidence to the influencing factors for the mentioned conditions through a real-world case-control study.
METHODS: An online survey consisting of 60 questions was implemented, collecting information on demographics, socioeconomics, genetic factors, lifestyle habits, environmental exposures, and skin care behaviors. Then we constructed univariate and multivariate logistic regressions. Furthermore, we analyzed the dose-response relationship between exposure and outcome.
RESULTS: A total of 399 individuals, including 94 acne patients, 107 melasma patients, and 91 rosacea patients were included. Acne and melasma were positively correlated with screen time (acne: odds ratio [OR]: 2.24, 95% confidence interval [CI]: 1.25-4.02; melasma: OR: 1.59, 95% CI: 1.09-2.31), while exercise exerted a protective effect on both acne (OR: 0.31, 95% CI: 0.13-0.77) and melasma (OR: 0.42, 95% CI: 0.22-0.80) in a dose-response relationship. In addition, males were associated with an elevated risk of acne (OR: 6.62, 95% CI: 1.01-43.26). Aging (OR: 1.15, 95% CI: 1.07-1.24) and irregular bowel movements (OR: 2.99, 95% CI: 1.11-8.08) were independent risk factors for melasma. Rosacea was positively associated with BMI (OR: 1.17, 95% CI: 1.01-1.35).
CONCLUSIONS: In our study, we highlighted exercise as an independent protective factor for both acne and melasma in a dose-response trend. Inversely, extended use of electronic equipment was independently associated with higher risks of acne and melasma. Rosacea, however, was more likely to be related with BMI.

OBJECTIVE: Orofacial clefts (OFCs) are some of the most common congenital anomalies worldwide. The aim of this case-control study was to evaluate the association of OFCs with selected maternal characteristics.
METHODS: Data on isolated non-syndromic cases of OFCs were extracted from the population-based registry of congenital anomalies of Tuscany. A sample of live-born infants without any congenital anomaly was used as the control group. We investigated the association with sex and some maternal characteristics: age, body mass index, smoking, and education. Adjusted odds ratios (OR) were calculated using a logistic regression model. Analyses were performed for the total OFCs and separately for cleft lip (CL) and cleft palate (CP).
RESULTS: Data on 219 cases and 37,988 controls were analyzed. A higher proportion of males (57.9%) was observed, particularly for CL. A decreasing trend among the maternal age classes was observed (OR:0.81 (95%CI 0.70-0.94)). Underweight mothers had a higher prevalence of OFCs, in particular for CL (OR:1.88 (95%CI 1.08-3.26)).
CONCLUSIONS: We found an association of OFCs with lower maternal age. The association with maternal age remains controversial and further epidemiological evidence is needed through multicenter studies. We observed that CL was more common in underweight mothers, suggesting actions of primary prevention.

BACKGROUND: Acne vulgaris is a very common inflammatory skin disease that significantly impacts the quality of life of affected individuals. Previous studies have indicated that individuals with acne vulgaris often have low levels of zinc, selenium, and vitamin D. However, these three nutrients have rarely been collectively examined in a single study. The objective of this study was to compare serum levels of zinc, selenium, and vitamin D in patients with acne vulgaris in comparison to a control group.
METHODS: This case-control study included 100 adult patients with acne vulgaris attending a dermatology clinic, in 2020. A group of 100 patients without acne vulgaris attending the same clinics were evaluated as controls. Participants\' sociodemographic characteristics, including age, sex, occupation, alcohol consumption, and tobacco smoking were recorded. In addition, anthropometric indices, such as weight and height, were measured and the body mass index (BMI) was calculated accordingly. Acne severity was determined using Tutakne and Chari\'s grading system. Serum zinc, selenium, and vitamin D levels were evaluated in peripheral blood samples of all the participants.
RESULTS: Acne patients and controls were comparable regarding age, sex, weight, height, BMI, occupation, alcohol consumption, and tobacco smoking (p > 0.05). Serum zinc, selenium, and vitamin D levels were all significantly lower in acne patients than in controls (p < 0.001). Furthermore, the frequency of abnormal zinc and vitamin D levels was significantly higher in acne patients (p = 0.002 and p = 0.001, respectively), but there was no significant difference between the two groups regarding abnormal serum selenium levels (p = 0.228). Also, serum zinc, selenium, and vitamin D levels lower levels in patients with grade 4 acne compared to other disease severity grades (p < 0.001).
CONCLUSIONS: Patients with acne vulgaris have lower levels of serum zinc, selenium, and vitamin D compared to the control group. Additionally, there is a correlation between the severity of the disease and lower levels of these nutrients.

BACKGROUND: The major burden of cervical cancer occurs in low- and middle-income countries. In Ghana, it is the second most common cancer among women. Infection with high-risk human papilloma virus (HPV) has been established as the cause of cervical cancer. As such, it is important to identify risk factors that may affect progression from HPV infection to cancer.
OBJECTIVE: We assessed the risk factors assocaited with cervical cancer in Ghana.
METHODS: To identify the risk factors for cervical cancer, we conducted an unmatched case-control study in two hospitals in Ghana where most cervical cancer cases are diagnosed. Women with histologically confirmed cervical cancer were the cases, whereas women without cancer seeking care at the two hospitals were controls. A structured questionnaire was administered to the women, after which cervical samples were sent for HPV deoxyribonucleic acid (DNA) testing.
RESULTS: Overall, 206 cases and 230 controls were recruited. After adjusting for possible confounders, women with the highest educational level had a significantly lower risk of cervical cancer than those with no or little formal education. Parity was a major risk factor (odd ratio [OR] for five or more children = 7.9; 95% CI: 2.3-27.6), with risk increasing with increasing parity (p for trend <0.001). Women reporting the use of a homemade sanitary towel during menstruation also had an increased risk of cervical cancer compared with women who used a pad (OR: 7.3; 95% CI: 2.5-22.0).
CONCLUSIONS: In this Ghanaian population, high parity and poor personal hygienic conditions were the main contributing factors to the risk of cervical cancer after adjustment for the presence of high-risk HPV genotypes.

UNASSIGNED: Early identification of new residual risk factors for coronary heart disease (CHD) is warranted. In this study, we aim to investigate the association between the serine concentration, an important amino acid in one-carbon metabolism, and CHD in Chinese hospitalized patients.
UNASSIGNED: This case-control study included 428 case-control pairs comprising patients with CHD with a maximum coronary artery stenosis degree of >70% and controls with stenosis of <30%. The individuals were matched by age, sex, and date of coronary angiography at Peking University First Hospital from January 1, 2016, to December 31, 2019. Conditional logistic regression was used to investigate the associations between the serine concentration and CHD.
UNASSIGNED: Patients with CHD were aged 63.48 ± 10.38 years, and 43.73% were male. Compared with controls, patients with CHD had a slightly lower serine concentration (13.35 ± 4.20 vs 13.77 ± 4.08 μg/mL), but the difference was not significant. In the multivariable conditional logistic regression analysis, for every 1 μg/mL increase in serine concentration, the odds of CHD decreased by 6% (95% confidence interval [CI] 0.90-0.99; P = 0.010). Patients with a serine concentration of ≥13.41 μg/mL had a lower CHD risk than those with a serine concentration of <13.41 μg/mL (odds ratio [OR] 0.57, 95% CI 0.39-0.84; P = 0.004). Subgroup analyses showed that sex interacted with the relationship between serine concentration and CHD (P interaction = 0.039), which was more significant in males (OR 0.93, 95% CI 0.87-0.98; P = 0.013) than in females.
UNASSIGNED: This study observed an inverse association between the serine concentration and CHD prevalence in Chinese hospitalized patients, which revealed that serine might play a protective role in CHD.

OBJECTIVE: Risk factors for pelvic floor disorders (PFDs) are not well understood in lower resource settings. The objective of this study is to determine the risk factors associated with stress urinary incontinence (SUI), urge urinary incontinence (UUI), and pelvic organ prolapse (POP) among women of reproductive age in rural Nepal.
METHODS: This is a case-control study nested within a community-based cross-sectional survey of parous women of reproductive age with PFDs in the Sarlahi District of Nepal. The presence of PFDs was confirmed by clinical assessment. Detailed sociodemographic information and histories were captured.
RESULTS: We examined 406 women; the mean (SD, range) age was 32.7 (8.5, 16-49) years, mean BMI (SD) was 19.7 (3.3) kg/m2, and median (range) number of pregnancies was 4 (1-11). Two hundred and three women (50.0%) had either SUI or UUI, 85 (17.8%) had both SUI and UUI, and 71 (17.5%) had POP at or beyond the hymen. After controlling for other variables significant on bivariate analysis, age (adjusted odds ratio [aOR] 1.06 [95% CI 1.03-1.09]), illiteracy (aOR 2.24 [95% CI 1.04-4.80]), and presence of upper gastrointestinal issues (aOR 3.30, [95% CI 1.77-6.16]) were independently associated with SUI/UUI. Age (aOR 1.05 [95% CI 1.02-1.09]), bispinous diameter (aOR 2.88 ([95% CI 1.11-7.47]), and subpubic angle (aOR 2.78 [95% CI 1.55-5.03]) were independently associated with POP.
CONCLUSIONS: Risk factors for PFDs in a homogenous community of parous women of reproductive age in rural Nepal are similar to those found in parous women in higher income countries.

A variety of factors can predispose newborns to have a low Apgar score after delivery. Identification of the determinants of low Apgar scores is an important first step to take to apply the necessary precautions. This study aimed to identify the determinants of low fifth-minute Apgar score after a Cesarean section. An institutional-based case-control study was conducted among mothers who deliver their newborns by Cesarean section in Nigist Eleni Mohammed Memorial Comprehensive Specialized Hospital, Ethiopia, from July 1, 2022, to September 30, 2022. Data were collected from 70 cases and 140 controls using a semi-structured checklist. A systematic random sampling technique was used to select both charts of mothers with cases and controls. Charts of mothers with newborns Apgar score less than 7 were considered as cases; whereas a similar group of charts of mothers with newborns with fifth-minute Apgar score greater than or equal to 7 were categorized as control. Descriptive statistics and bivariable and multivariable binary logistic regression analyses were conducted to describe the mothers and newborns and identify determinants of the fifth-minute low Apgar score, respectively. Adjusted odds ratios (AOR) with their respective 95% confidence interval (CI) were used to declare the determinant factors, and the statistical significance was set at P < 0.05. In total, 140 controls and 70 cases of mothers charts were enrolled in this study. The Mean ± SD age of mothers of cases and controls were 26.9 ± 4.9 and 27.06 ± 4.1 years, respectively. General anaesthesia (AOR = 4.2; 95% CI: 1.9 ‒ 9.3), rural residence (AOR = 3.7, 95% CI, 1.7‒8.1), low birth weight (AOR = 3.2, 95% CI, 1.3‒7.8), and emergency Cesarean section (AOR = 2.6; 95% CI: 1.2 ‒ 5.8) were identified determinant factors of low fifth minute Apgar score. A fifth-minute low Apgar score was significantly associated with newborns delivered through emergency Cesarean section, low birth weight, rural residence, and delivered from mothers who had undergone Cesarean section under general anaesthesia.

OBJECTIVE: This study was undertaken to validate a set of candidate biomarkers of seizure susceptibility in a retrospective, multisite case-control study, and to determine the robustness of these biomarkers derived from routinely collected electroencephalography (EEG) within a large cohort (both epilepsy and common alternative conditions such as nonepileptic attack disorder).
METHODS: The database consisted of 814 EEG recordings from 648 subjects, collected from eight National Health Service sites across the UK. Clinically noncontributory EEG recordings were identified by an experienced clinical scientist (N = 281; 152 alternative conditions, 129 epilepsy). Eight computational markers (spectral [n = 2], network-based [n = 4], and model-based [n = 2]) were calculated within each recording. Ensemble-based classifiers were developed using a two-tier cross-validation approach. We used standard regression methods to assess whether potential confounding variables (e.g., age, gender, treatment status, comorbidity) impacted model performance.
RESULTS: We found levels of balanced accuracy of 68% across the cohort with clinically noncontributory normal EEGs (sensitivity =61%, specificity =75%, positive predictive value =55%, negative predictive value =79%, diagnostic odds ratio =4.64, area under receiver operated characteristics curve =.72). Group level analysis found no evidence suggesting any of the potential confounding variables significantly impacted the overall performance.
CONCLUSIONS: These results provide evidence that the set of biomarkers could provide additional value to clinical decision-making, providing the foundation for a decision support tool that could reduce diagnostic delay and misdiagnosis rates. Future work should therefore assess the change in diagnostic yield and time to diagnosis when utilizing these biomarkers in carefully designed prospective studies.
