The burden experienced by family caregivers of patients with epilepsy attending the government psychiatric hospital, Kaduna, Nigeria

BACKGROUND: Caring for patients with chronic medical and psychiatric disorders is associated with significant burden. However little is known about the burden experience by caregivers of patients with epilepsy in Nigeria. The objective of this study, therefore, was to assess the level and correlates of burden among caregivers of patients with epilepsy. METHODS: It was a cross-sectional study carried out among 231 eligible caregivers of patients with epilepsy attending the psychiatric clinic of government psychiatric hospital in Kaduna, Northern Nigeria. Socio demographic/clinical characteristics of patients and sociodemographic characteristics of caregivers were recorded, and the Zarit Burden Interview administered to caregivers to assess their experience of burden. RESULTS: The mean age of the caregivers was 43.6 ±9.5 years, 52.4% lived outside Kaduna and the mean seizure-free period for the patients was 26.4 ±36.5 weeks. One hundred and twenty (51.9%) caregivers had high burden. High burden was significantly associated with patients aged less than20 years, patient’s unemployment, long duration of epilepsy, short seizure-free period, family history of epilepsy and living outside Kaduna (p valu

Investigating Users’ IT Adaptation Behaviors: A Case of a Computerized Work System

IS research has shown that successful IT implementation projects rely on the extent to which IT users respond and adapt to the new technology and the changes the new technology comes with. Although the phenomenon of user IT adaptation has been studied previously in IS literature our understating of user IT adaptation is still limited. Drawing on the Coping Model of User Adaptation (CMUA) and the Approach vs. Avoidance model of coping, this study seeks to investigate how different user adaptation efforts evolve over time and subsequently influence IT use outcomes. Using a qualitative case study approach, 68 interviews were conducted at a medical center in Iran after the implementation of a Work System Computerization project. Our results indicate that emotions have a great influence on IT users’ adaptation efforts. Also, users’ IT appraisal might not necessarily happen in sequence as suggested by existing literature. Finally, our findings highlight the theoretical importance of preserving the distinction between approach- and avoidance-oriented emotion-focused adaptation efforts in exploring how emotion-focused efforts may influence system usage

Spatiotemporal Variation and Health Risk Assessment of Selected Polycyclic Aromatic Hydrocarbons and Pesticides in Ogun River, Lagos, Nigeria

Studying the spatiotemporal distribution and health risks associated with polycyclic aromatic hydrocarbons and pesticides in a river is crucial for understanding the impacts of these contaminants on human health. Hence, the objective of this paper was to investigate the spatiotemporal variation and health risk assessment of selected polycyclic aromatic hydrocarbons and pesticides in Ogun River, Lagos, Nigeria. The water samples were analyzed using gas chromatography coupled with MSD model 5977A. The results show a diverse distribution of PAHs across the sites, with Naphthalene and Acenaphthylene being the most frequently detected, having significantly higher concentrations in the dry season than in the rainy season. There was a significant difference in the mean amounts of pesticides at site 1 compared to other sites.  While some pesticides recorded higher mean values in the rainy season, others had higher mean values in the dry season. Similar to PAHs, most pesticides had higher mean values in year 1 than in year 2. Most of the pesticides and PAHs posed significant non-cancer risks (HQ > 1) through oral exposure, except Glyphosate and Imidacloprid at all the sites; and Acenaphthene and Anthracene at site 4. There was also a significant health risk through dermal exposure to Heptachlor and Dichlorvos at S4 and Aldrin at S1. The cancer risk through oral exposure to all the detected carcinogenic pollutants is significant (CR >1×10-4), except Lindane at S4, which was within the acceptable range. Benzo[a]anthracene and Benzo[a]pyrene posed significant cancer risk through dermal exposure at S3 and heptachlor at S1. The study indicated that the observed spatial and temporal variations are different for specific pollutants. There is a high probability of adverse carcinogenic and non-carcinogenic risks for people who rely on the river for various purposes

Comparative studies on the structure of an upland African stream ecosystem

Upland stream systems have been extensively investigated in Europe, North America and Australasia and many of the central ideas concerning their function are based on these systems. One central paradigm, the river continuum concept is ultimately derived from those North American streams whose catchments remain forested with native vegetation. Streams of the tropics may or may not fit the model. They have been little studied. The Amani Nature Reserve in the East Usambara Mountains of north-eastern Tanzania offers an opportunity to bring these naturally forested systems to the attention of the ecological community. This article describes a comparison made between two lengths of the River Dodwe in this area. The work was carried out by a group of postgraduate students from eighteen European and African countries with advice from five staff members, as part of a course organised by the Tropical Biology Association. Rigorous efforts were made to standardise techniques, in a situation where equipment and laboratory facilities were very basic, through a management structure and deliberate allocation of work to specialists in each area.The article offers a summary of invertebrate communities found in the stream and its biomass. Crabs seem to be the key organism in both sections of the streams

Comparison of respondent-reported and sensor-recorded latrine utilization measures in rural Bangladesh: a cross-sectional study.

Background: Health improvements realized through sanitation are likely achieved through high levels of facilities utilization by all household members. However, measurements of sanitation often rely on either the presence of latrines, which does not guarantee use, or respondent-reported utilization of sanitation facilities, which is prone to response bias. Overstatement of sanitation metrics limits the accuracy of program outcome measures, and has implications for the interpretation of related health impact data. Methods: We conducted a cross-sectional study of 213 households in 14 village water, sanitation and hygiene committee clusters throughout rural Bangladesh and used a combined data- and relationship-scale approach to assess agreement between respondent-reported latrine utilization and sensor-recorded measurement. Results: Four-day household-level respondent-reported defecation averaged 28 events (inter-quartile range [IQR] 20-40), while sensor-recorded defecation averaged 17 events (IQR 11-29). Comparative analyses suggest moderately high accuracy (bias correction factor=0.84), but imprecision in the data (broad scatter of data, Pearson's r=0.35) and thus only weak concordance between measures (ρc=0.29 [95% BCa CI 0.15 to 0.43]). Conclusions: Respondent-reported latrine utilization data should be interpreted with caution, as evidence suggests use is exaggerated. Coupling reported utilization data with objective measures of use may aid in the estimation of latrine use

Prenatal household air pollutant exposure is associated with reduced size and gestational age at birth among a cohort of Ghanaian infants.

BACKGROUND: Low birth weight and prematurity are important risk factors for death and disability, and may be affected by prenatal exposure to household air pollution (HAP). METHODS: We investigate associations between maternal exposure to carbon monoxide (CO) during pregnancy and birth outcomes (birth weight, birth length, head circumference, gestational age, low birth weight, small for gestational age, and preterm birth) among 1288 live-born infants in the Ghana Randomized Air Pollution and Health Study (GRAPHS). We evaluate whether evidence of malaria during pregnancy, as determined by placental histopathology, modifies these associations. RESULTS: We observed effects of CO on birth weight, birth length, and gestational age that were modified by placental malarial status. Among infants from pregnancies without evidence of placental malaria, each 1 ppm increase in CO was associated with reduced birth weight (-53.4 g [95% CI: -84.8, -21.9 g]), birth length (-0.3 cm [-0.6, -0.1 cm]), gestational age (-1.0 days [-1.8, -0.2 days]), and weight-for-age Z score (-0.08 standard deviations [-0.16, -0.01 standard deviations]). These associations were not observed in pregnancies with evidence of placental malaria. Each 1 ppm increase in maternal exposure to CO was associated with elevated odds of low birth weight (LBW, OR 1.14 [0.97, 1.33]) and small for gestational age (SGA, OR 1.14 [0.98, 1.32]) among all infants. CONCLUSIONS: Even modest reductions in exposure to HAP among pregnant women could yield substantial public health benefits, underscoring a need for interventions to effectively reduce exposure. Adverse associations with HAP were discernible only among those without evidence of placental malaria, a key driver of impaired fetal growth in this malaria-endemic area

A cluster randomised trial of cookstove interventions to improve infant health in Ghana.

INTRODUCTION: Household air pollution from solid fuel combustion for cooking and heating is a leading cause of childhood morbidity and mortality worldwide. We hypothesised that clean cooking interventions delivered during pregnancy would improve child health. METHODS: We conducted a cluster randomised trial in rural Ghana to test whether providing pregnant women liquefied petroleum gas (LPG) cookstoves or improved biomass cookstoves would reduce personal carbon monoxide and fine particulate pollution exposure, increase birth weight and reduce physician-assessed severe pneumonia in the first 12 months of life, compared with control participants who continued to cook with traditional stoves. Primary analyses were intention-to-treat. The trial was registered with ClinicalTrials.gov and follow-up is complete. RESULTS: Enrolment began on 14 April 2014, and ended on 20 August 2015. We enrolled 1414 pregnant women; 361 in the LPG arm, 527 in the improved biomass cookstove arm and 526 controls. We saw no improvement in birth weight (the difference in mean birth weight for LPG arm births was 29 g lighter (95% CI -113 to 56, p=0.51) and for improved biomass arm births was 9 g heavier (95% CI -64 to 82, p=0.81), compared with control newborns) nor severe child pneumonia (the rate ratio for pneumonia in the LPG arm was 0.98 (95% CI 0.58 to 1.70; p=0.95) and for the improved biomass arm was 1.21 (95% CI 0.78 to 1.90; p=0.52), compared with the control arm). Air pollution exposures in the LPG arm remained above WHO health-based targets (LPG median particulate matter less than 2.5 microns in diameter (PM2.5) 45 µg/m³; IQR 32-65 vs control median PM2.5 67 µg/m³, IQR 46-97). CONCLUSIONS: Neither prenatally-introduced LPG nor improved biomass cookstoves improved birth weight or reduced severe pneumonia risk in the first 12 months of life. We hypothesise that this is due to lower-than-expected exposure reductions in the intervention arms. TRIAL REGISTRATION NUMBER: NCT01335490

Domestic Violence, Intrahousehold Bargaining and Child Health Development in Ghana

I explore a unique exogenous instrument to examine how the intra-familial position of women influence health outcomes of their children using micro data from Ghana Demographic and Health Survey, 2008. Using the 2 SLS-IV estimation technique, I build a model of household bargaining and child health development with perceptions of women regarding wife-beating and marital rape in the existence of domestic violence laws, in Ghana. Even though the initial OLS estimates suggest that women’s participation in decisions regarding purchases of household consumption goods help to improve child health outcomes, the IV estimates reveal that the presence of endogeneity underestimates the impact of women’s bargaining power on child health outcomes. Our Hausman test for endogeneity also confirms that health development of children is mediated through domestic violence laws, which protect women from physical and sexual abuse in the household

Twelve-month observational study of children with cancer in 41 countries during the COVID-19 pandemic

Introduction Childhood cancer is a leading cause of death. It is unclear whether the COVID-19 pandemic has impacted childhood cancer mortality. In this study, we aimed to establish all-cause mortality rates for childhood cancers during the COVID-19 pandemic and determine the factors associated with mortality. Methods Prospective cohort study in 109 institutions in 41 countries. Inclusion criteria: children <18 years who were newly diagnosed with or undergoing active treatment for acute lymphoblastic leukaemia, non-Hodgkin's lymphoma, Hodgkin lymphoma, retinoblastoma, Wilms tumour, glioma, osteosarcoma, Ewing sarcoma, rhabdomyosarcoma, medulloblastoma and neuroblastoma. Of 2327 cases, 2118 patients were included in the study. The primary outcome measure was all-cause mortality at 30 days, 90 days and 12 months. Results All-cause mortality was 3.4% (n=71/2084) at 30-day follow-up, 5.7% (n=113/1969) at 90-day follow-up and 13.0% (n=206/1581) at 12-month follow-up. The median time from diagnosis to multidisciplinary team (MDT) plan was longest in low-income countries (7 days, IQR 3-11). Multivariable analysis revealed several factors associated with 12-month mortality, including low-income (OR 6.99 (95% CI 2.49 to 19.68); p<0.001), lower middle income (OR 3.32 (95% CI 1.96 to 5.61); p<0.001) and upper middle income (OR 3.49 (95% CI 2.02 to 6.03); p<0.001) country status and chemotherapy (OR 0.55 (95% CI 0.36 to 0.86); p=0.008) and immunotherapy (OR 0.27 (95% CI 0.08 to 0.91); p=0.035) within 30 days from MDT plan. Multivariable analysis revealed laboratory-confirmed SARS-CoV-2 infection (OR 5.33 (95% CI 1.19 to 23.84); p=0.029) was associated with 30-day mortality. Conclusions Children with cancer are more likely to die within 30 days if infected with SARS-CoV-2. However, timely treatment reduced odds of death. This report provides crucial information to balance the benefits of providing anticancer therapy against the risks of SARS-CoV-2 infection in children with cancer
