The Influence of Sex-role Self-Concept on Academic Performance among Secondary School Students in Kenya

The study examined the influence of sex-role selfconcept on academic performance among students in coeducational secondary schools in Siaya District The sample comprised 154 boys and 89 girls in Form 3 Bem s Sex-role Inventory BSRI was used to collect data on masculinity and femininity while students academic scores were obtained from school records Linear Regression analysis revealed that sex-role self-concept predicts academic performance Sex-role self-concept also explained significant variance in academic scores The results further showed significant difference between the academic mean scores of androgynous masculine feminine and undifferentiated students However the androgynous students had better academic mean score than the other students The results support the view that sex-role self-concept is a predictor of achievement than gende

Effect of Informal Settlements on Water Quality

ABSTRACT Businesses and other informal settlements have said to be the key of polluters of the Kabuthi River. The population pollutes streams of water, especially Kabuthi River by disposing waste into the rivers. This makes the water unsafe for domestic use by the big slums populations that has to buy water for drinking, cooking, washing clothes and feeding animals yet there is a stream that passes by their homes. The settlements include Gachui, Kwanjiku, Mutuini, Kirigu,Mutego and Waithaka among others. The study was also set out to establish the key polluters of Kabuthi River by investigating the activities the river and other mentioned informal settlements where the stream passes. To make this study possible both primary and secondary data were used. Primary data sources included field observations and 150 questionnaires completed by the residents. A total of 16 villages around the streams were selected where interviews were conducted and questionnaires filled through random sampling. Three water samples were taken from River Kabuthi at 1Km interval and tested in the laboratory. Two other waste water samples results were borrowed from study on slaughter houses located in the areas along which the stream flows to establish whether they too contributed to the pollution of urban streams. Data analysis and presentation was undertaken using both general qualitative and quantitative methods. The analysis of samples was undertaken in the Environmental Health Engineering Laboratory at University of Nairobi with additional help by Davis and Shirtliff

Effects of Croton menyharthii and Uvariodendron kirkii extracts on ovarian corpora lutea and reproductive hormones.

Uvariodendron kirkii and Croton menyharthii are traditionally used as fertility regulators in Kenya. The rapidly increasing population has put a strain on the limited resources and poses serious challenge to national planning. The aim of the study was to validate the traditional claims by investigating the effect of root bark extract of both plants on reproductive hormones and ovarian structures. Twenty five mature normocyclic female winstar rats were used. Group 1 consisted of 5 animals that acted as control. Group 2 and 3 with 5 animals each; received 500 and 800mg/Kg Croton menyharthii respectively on alternative days for 28 days through intra- abdominal gavage. Group 4 and 5 were treated in a similar manner but received Uvariodendron kirkii aqueous extract. Serum was harvested from all animals on 28th day and hormone levels determined. Left ovaries were harvested and processed for histomorphology. Both Croton menyharthii and Uvariodendron kirkii caused a significant increase of progesterone in a dose dependent manner. Croton menyharthii extracts caused a degeneration of corpora lutea. At 800mg/kg Croton menyharthii caused a significant increase in corpora lutea numbers but a decline in size. Uvariodendron kirkii caused hypertrophy and a significant increase in corpora lutea numbers. Enhanced/ hypertrophied corpora lutea possibly led to high levels of progesterone seen, interfered with the implantation window due to disrupted hormonal milieu thereby leading to compromised fertility and implantation index. The study validates the traditional use of the plant in fertility regulation. We suggest further investigation on these potential plants to address the call for novel contraceptive drugs

Paediatric and obstetric outcomes at a faith-based hospital during the 100-day public sector physician strike in Kenya

Published reviews of national physician strikes have shown a reduction in patient mortality. From 5 December 2016 until 14 March 2017, Kenyan physicians in the public sector went on strike leaving only private (not-for-profit and for-profit) hospitals able to offer physician care. We report on our experience at AIC-Kijabe Hospital, a not-for-profit, faith-based Kenyan hospital, before, during and after the 100-day strike was completed by examining patient admissions and deaths in the time periods before, during and after the strike. The volume of patients increased and exceeded the hospital's ability to respond to needs. There were substantial increases in sick newborn admissions during this time frame and an additional ward was opened to respond to this need. Increased need occurred across all services but staffing and space limited ability to respond to increased demand. There were increases in deaths during the strike period across the paediatric medical, newborn, paediatric surgical and obstetric units with an OR (95% CI) of death of 3.9 (95% CI 2.3 to 6.4), 4.1 (95% CI 2.4 to 7.1), 7.9 (95% CI 3.2 to 20) and 3.2 (95% CI 0.39 to 27), respectively. Increased mortality across paediatric and obstetrical services at AIC-Kijabe Hospital correlated with the crippling of healthcare delivery in the public sector during the national physicians' strike in Kenya

Plasma proteomic signatures of enteric permeability among hospitalized and community children in Kenya and Pakistan

We aimed to establish if enteric permeability was associated with similar biological processes in children recovering from hospitalization and relatively healthy children in the community. Extreme gradient boosted models predicting the lactulose-rhamnose ratio (LRR), a biomarker of enteric permeability, using 7,500 plasma proteins and 34 fecal biomarkers of enteric infection among 89 hospitalized and 60 community children aged 2–23 months were built. The R2 values were calculated in test sets. The models performed better among community children (R2: 0.27 [min-max: 0.19, 0.53]) than hospitalized children (R2: 0.07 [min-max: 0.03, 0.11]). In the community, LRR was associated with biomarkers of humoral antimicrobial and cellular lipopolysaccharide responses and inversely associated with anti-inflammatory and innate immunological responses. Among hospitalized children, the selected biomarkers had few shared functions. This suggests enteric permeability among community children was associated with a host response to pathogens, but this association was not observed among hospitalized children

Exploring the influence of postnatal depression on neonatal care practices among mothers in Western Kenya: A qualitative study

Background: Postnatal depression (PND) is associated with adverse infant neurodevelopmental outcomes. Evidence is limited on how PND influences neonatal (<28 days old) outcomes in low- and middle-income countries, such as Kenya, which bear the global burden of neonatal morbidity and mortality. Objectives: To explore how PND influences neonatal feeding and care practices among women in the early postnatal period in rural Western Kenya. Design: A cross-sectional study. Methods: Semi-structured interviews were conducted at 2-weeks postpartum among mothers of newborn infants identified <72 h old from the postnatal wards and clinics across five health facilities in Kisumu County of Western Kenya. They were all screened for features suggestive of postnatal depression using the Edinburgh Postnatal Depression Scale. Results: Twenty-four mothers were interviewed, 13 of whom had features suggestive of PND. All mothers experienced health or socio-economic adversities in the perinatal period, including traumatic deliveries, financial constraints, and challenging relationships with partners/other family members. Feeding difficulties due to perceived insufficient breastmilk were a particular challenge for mothers with features of PND, who were more likely to introduce complementary feeds. Maternal health-seeking decisions were influenced by high financial cost, long waiting times and poor interactions with health care providers that induced stress and fear among mothers. Maternal caregiving capacity was influenced by her ability to juggle other household duties, which was difficult for mothers with features suggestive of PND. Support from friends and relatives positively impacted maternal mood and caregiving ability. Conclusion: Mothers experienced many stress-inducing events in the perinatal period which potentially exacerbated features of PND in the immediate postnatal period. Women with features of PND were particularly vulnerable to these stressors that influenced infant caregiving practices. Addressing the socio-economic challenges and health system gaps that include scale up of compassionate and respectful care for women during pregnancy and childbirth, as well as early screening and intervention of PND, through enhanced referral pathways between health facilities and community support structures, could mitigate against the impact of PND on neonatal caregiving

Assessment of the Ecological Health of Afrotropical Rivers Using Fish Assemblages: A Case Study of Selected Rivers in the Lake Victoria Basin, Kenya

Streams and rivers are globally threatened ecosystems because of increasing levels of exploitation, habitat degradation and other anthropogenic pressures. In the Lake Victoria Basin (LVB) in East Africa, these threats are mostly caused by unsustainable land use; however, the monitoring of ecological integrity of river systems has been hampered by a lack of locally developed indices. This study assessed the health of four rivers (Nzoia, Nyando, Sondu–Miriu and Mara) on the Kenyan side of the LVB using physicochemical water quality parameters and a fish-based index of biotic integrity (IBI). Fish tolerance ranking was derived from principal component analysis of water quality parameters, and the concept of niche breadth (NB). The relationship between fish species and water quality parameters was examined with canonical correspondence analysis, whereas community metrics and stressors were evaluated through Pearson network correlation analysis. Fish species richness, trophic structures, taxonomic composition and species tolerance were used to generate the metrics for fish-based IBI. NB showed that most of the fish species were moderately tolerant to poor water. Moderately tolerant and intolerant fish species were negatively correlated with a high level of organic loading in the Mara River. Fish-based IBI scores for the rivers ranged from 26 to 34, with Sondu–Miriu scoring the lowest. Our results show that the cumulative effect of stressors can adequately rank fish species tolerance according to the disturbance gradients and further develop regional metrics to assess river health. Despite the fact that fish communities are declining, continual management and enforcement of environmental regulations are important, with conservation and management of headwaters and low-order streams being essential while they are still species rich

Impact of a two-way short message service (SMS) to support maternally administered childhood mid-upper arm circumference monitoring and expand malnutrition screening in Kenya: the Mama Aweza trial protocol

Introduction Over 52 million children under 5 years of age become wasted each year, but only 17% of these children receive treatment. Novel methods to identify and deliver treatment to malnourished children are necessary to achieve the sustainable development goals target for child health. Mobile health (mHealth) programmes may provide an opportunity to rapidly identify malnourished children in the community and link them to care.Methods and analysis This randomised controlled trial will recruit 1200 children aged 6–12 months at routine vaccine appointments in Migori and Homa Bay Counties, Kenya. Caregiver–infant dyads will be randomised to either a maternally administered malnutrition monitoring system (MAMMS) or standard of care (SOC). Study staff will train all caregivers to measure their child’s mid-upper arm circumference (MUAC). Caregivers in the MAMMS arm will be given two colour coded and graduated insertion MUAC tapes and be enrolled in a mHealth system that sends weekly short message service (SMS) messages prompting caregivers to measure and report their child’s MUAC by SMS. Caregivers in the SOC arm will receive routine monitoring by community health volunteers coupled with a quarterly visit from study staff to ensure adequate screening coverage. The primary outcome is identification of childhood malnutrition, defined as MUAC &lt;12.5 cm, in the MAMMS arm compared with the SOC arm. Secondary outcomes will assess the accuracy of maternal versus health worker MUAC measurements and determinants of acute malnutrition among children 6–18 months of age. Finally, we will explore the acceptability, fidelity and feasibility of implementing the MAMMS within existing nutrition programmes.Ethics and dissemination The study was approved by review boards at the University of Washington and the Kenya Medical Research Institute. A data and safety monitoring board has been convened, and the results of the trial will be published in peer-reviewed scientific journals, presented at appropriate conferences and to key stakeholders.Trial registration number NCT03967015; Pre-results
