ABSTRACT
Intraventricular hemorrhage (IVH) is one of the medical issues that preterm infants are susceptible to as a result of their difficulty adjusting to life outside the womb. It is bleeding into the ventricular system from the germinal matrix, a highly cellular and vascular tissue that is only seen in preterm newborns and ruptures easily. The study aims to assess the magnitude and associated factors of IVH in preterm neonates. Methods: A hospital-based cross-sectional study was conducted at Tibebe Ghion Specialized Hospital (TGSH) from 14 March 2022 to 15 August 2022. The neonatal referral form, the mother's medical file, an in-person interview with the mother, and bedside cranial sonography were used to collect clinical data. After data were entered into Epi Info and exported to Scientific Program for Social Science (SPSS), analysis was carried out using binary and multivariable logistic regression. Results: The overall magnitude of IVH in preterm newborns among preterm neonates admitted to TGSH was 53 (27.04%) (95% CI: 20.9-32.2%). In the multivariable logistic regression analysis, a birth weight of between 1500 and 2000 g (OR: 0.38, 95% CI: 0.18-0.79) were negative, and those neonates with gestational age between 28 and 32 weeks (OR: 2.14, 95% CI: 1.04-4.41) were positively associated with the occurrence of IVH. Conclusion: The study discovered that the magnitude of IVH is slightly higher than that of prior studies done in different parts of the world, and those neonates delivered at early gestational ages and those with very low birth weight have a higher incidence of IVH. Both guardians and health providers should give more attention to those neonates born at an early gestational age and with small birth weight.
ABSTRACT
Background: Globally, women with disabilities have two times higher chance of suffering from violence compared to their non-disabled peers due to double discrimination. However, there is little evidence that quantifies the situation in this segment of the population by considering disability-related factors which make this group more vulnerable to gender-based violence in Ethiopia. Objective: To assess the prevalence of gender-based violence and its associated factors among women with disabilities in Jimma town, southwest Ethiopia, 2020. Methods: A community based cross-sectional study was conducted among a total of 308 women with disabilities. Bivariate and multivariable logistic regression analyses were carried out to identify factors associated with gender-based violence. The significance of the association was decided by using the 95% confidence interval of AOR at a p-value of <0.05 in the multivariable analysis. Results: The lifetime prevalence of gender-based violence among women with disabilities was found to be 73.1, while 46.1% had experienced it during the last 12 months. Gender-based violence in the past 12 months was significantly associated with non-schooling (AOR=5.10; 95% CI, 1.51, 17.14), being in age group of 20-34 (AOR=3.5; 95% CI, 1.74, 7.30), having visual impairment (AOR=3.1; 95% CI, 1.27, 7.54), having hearing impairment (AOR=3.0; 95% CI, 1.36, 6.89), alcohol use behavior (AOR=4.1; 95% CI, 1.74, 9.55), and perceived stigma and discrimination (AOR=4.2; 95% CI, 2.44, 7.39). Conclusion: Prevalence of gender-based violence among women with disabilities was found to be high in the study area. Educational status, age, type of disability, alcohol use behavior, and perceived stigma and discrimination were independent predictors of gender-based violence. Measures have to be taken to curb the problem by taking integrated interventions like enrolling girls in school and targeted health education towards identified factors by considering the heterogeneity of disabilities.
ABSTRACT
The need for sensors that measure the acetone content of exhaled breath for diabetes severity has recently increased. Clinical researchers have reported less than 0.8 ppm acetone concentration in the exhaled breath of an average individual, while that for a diabetic patient is higher than 1.8 ppm. This work reports the development of two sets of evanescent wave-based fiber optic sensor coated with SnO2 thin film and bilayer of SnO2/MoS2 to detect different acetone concentrations (0-250 ppm). In each set, we have studied the effect of clad thickness (chemical etch time 5min, 10 min, 15 min, 25 min, 40 min, and complete clad removal) to optimize the clad thickness for a better response. In Set 1, SnO2 thin film was used as the sensing layer, while in Set 2 a bilayer of SnO2 thin film/ MoS2 was used. Enhanced sensor response of ~23.5% is observed in the Set 2 probe with a response and recovery time of ~14 s/~17 s. A SnO2/MoS2-coated sensor prototype is developed using LEDs of different wavelength and intensity detector; its potential to detect different concentrations of acetone is tested. X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Ultraviolet (UV) Spectroscopy, and Ellipsometry were used to study the structural, morphological and optical properties of the sensing layers. The present study indicates that the SnO2/MoS2-coated sensor has the potential to create a handheld sensor system for monitoring diabetes.
