Assessing The Roles Of Community Based Service Providers And Healthcare Workers In The Prevention Of Relapse Among Tb Infected Patients In Namibia

ABSTRACT Background: Mycobacterium Tuberculosis commonly referred to as (TB) is still one of the major health concerns, with high prevalence globally as well as in Namibia. While significant progress has been achieved in the prevention and treatment services of TB in the country, including use of community-based service providers and community-based health workers, the number of relapse cases remained high. The study aimed at assessing the role of Community Based Service Providers in the prev...

Prevalence And Molecular Characterisation Of Group B Streptococcus In Pregnant Women From Hospitals In Ohangwena And Oshikoto Regions Of Namibia

ABSTRACT BACKGROUND Group B streptococcus (GBS) naturally colonises the lower gastrointestinal and female genitourinary tract. It poses a great risk of morbidity and mortality to infants born to colonised mothers. It is highly implicated in maternal infections such as endometritis and chorioamnionitis as well as neonatal infections such as pneumonia, meningitis and septicaemia. It also causes stillbirths and miscarriages in colonised women. Group B streptococcus infection in neonates is class...

Effects Of Air Pollution On Tomato Plants (Lycopersicon Esculentum) Grown Along Waiyaki Highway In Nairobi County, Kenya

ABSTRACT Vehicle exhaust fumes emission, as one of leading major source among smoke producing air pollutants, was examined in this study. Nairobi, a mega-city with increasingly high levels of air pollution was studied with special emphasis on one of its roads, Waiyaki Highway. Objectives were to find if there is air pollution, air pollution effects growth and stress of plants. This road was investigated to gain scientific understanding of the effects of vehicle fumes on plants. Hotspots (ICEA...

Assessment Of The Effects Of Land Use Methods Contributing To Watershed Degradation In Makueni County

ABSTRACT Land use changes, rapid population growth, poverty, climate change variability and lack of livelihoods diversification aggravate watershed degradation through inappropriate land use methods resulting to water scarcity, land and water pollution, and governance issues. Soil erosion and siltation has led to land denudation, habitat loss and farm lands losing their soil fertility and compromising food security. The main objective of the study was to find out how land use methods influenc...

Effects Of Physico-Chemical Parameters Of Water On Tilapia (Oreochromis Niloticus) Growth In Earthen Ponds In Teso North Sub County, Busia County, Kenya.

ABSTRACT Global, regional and national production of Nile Tilapia (Oreochromis niloticus) has faced challenges of low yields and lack of crucial culture information. Farmers in Teso North Sub County recorded lower yields than expected in 2009 despite having been provided with inputs. Factors responsible for the low production had not been established and water quality was suspected to be among them. The purpose of this study was to assess the effects of water quality on the growth of Nile Til...

Ecological Risk Assessment, Uptake Pattern Analysis And Depuration Studies Of Heavy Metals Using Selected Fish Species And Cultured Gill Epithelial Cells

Abstract Aquatic pollution by heavy metals remains a recurrent problem globally due to their persistence, toxicity and ability to accumulate in biological systems. This study investigated the pollution trend, ecological and public health risks associated with heavy metal pollution in the Lagos Lagoon as well as pattern of interaction among heavy metals that can be exploited for remediation of exposed aquatic organisms. Heavy metal content in surface water, sediment and biota were analyzed us...

An Assessment Of Socio-Economic Factors Influencing Electronic Waste Management In Kisumu Central Business District, Kisumu City, Kenya.

ABSTRACT The ever increasing levels of electronic waste (e-waste) and limited capacities for disposal and recycling have worsened e-waste management considering only 10% of e-waste is properly managed globally. In developed countries, e-waste management is guided by extended producer responsibility frameworks that ensure e-waste collection and recycling through consumer participation whereas, in Asia and Africa e-waste is managed through inefficient solid waste systems resulting to degradatio...

Effect Of Pesticides Use On Honeybee (Apis Mellifera L.) Mortality And Honey Production In Transmara West Sub-County, Narok County, Kenya

ABSTRACT The honeybee (Apis mellifera L.) produces honey and cross pollinates plants for improved socioeconomic wellbeing. However its colony populations globally and locally have been declining. In Transmara West Sub-county, hive colonization and honey yields have been low, which is due to the decline in honeybee population believed to be caused by pesticides use and pests attack. Although their relative contributions are unknown, Beekeepers suspect pesticides use hold a key role in colony p...

Assessment Of Dust Exposure And Risk Of Chronic Respiratory Diseases Among Stone Corrie Quarry Workers In Namibia, 2018

ABSTRACT Quarry mining produces substantial dust amounts bearing an adverse effect on human health in several ways, mainly the respiratory system. Even though employers are obligated to protect their employees from occupational hazards, the quarry mining industry in Namibia has failed to honour that obligation. This study investigated quarry workers and the surrounding community’s exposure to dust as well as their risk of getting chronic respiratory diseases in the Erongo region of Namibia....

Impact Of Diabetes On The Treatment Of Tb Patients In Khomas Region, Namibia

ABSTRACT Introduction Tuberculosis and diabetes mellitus are public health challenges globally. The World Health Organization (WHO) Global report on diabetes reiterated that diabetes is a well-known risk factor for tuberculosis (TB) and that diabetes is associated with poor tuberculosis treatment outcomes, while tuberculosis is linked with deteriorating glycemic control. Namibia is among the top 30 high TB burden countries in the world (WHO, 2016) and added to that is the increasing prevalenc...
