Abstract Globally, dental caries has affected nearly 100% of adult teeth. Dental caries is caused when microbial biofilm converts free sugar contained in such foods and drinks into acid which corrodes the tooth structure. In Kenya, the prevalence is 34%. This high prevalence has led to the negative impact associated with the disease. Therefore, this study’s main aim was to determine the prevalence of dental caries among adult patients in Bungoma County, Kenya. This study was conducted in B...
Abstract/Overview Large reductions in malaria transmission and mortality have been achieved over the last decade, and this has mainly been attributed to the scale-up of long-lasting insecticidal bed nets and indoor residual spraying with insecticides. Despite these gains considerable residual, spatially heterogeneous, transmission remains. To reduce transmission in these foci, researchers need to consider the local demographical, environmental and social context, and design an appropriate...
Abstract/Overview Health in low and middle income countries is on one hand characterized by a high burden associated with preventable communicable diseases and on the other hand considered to be under-documented due to improper basic health and demographic record-keeping. health and demographic surveillance systems (HDSSs) have provided researchers, policy makers and governments with data about local population dynamics and health related information. In order for an HDSS to deliver high ...
Abstract Background and objectives: Kigelia africana is a medicinal plant growing naturally in many parts of Africa. In Kenya, a water concoction of the plant is used to treat breast and prostate cancers. Laboratory data on its anti-cancer activity and active principles is limited, hence no scientific rationale for its medicinal use. This study reports on in-vitro toxic activities of dichloromethane and methanol extracts of the plant against human breast cancer cells and phytochemical screen...
Abstract A cross-sectional study was carried out to determine foot-and-mouth disease (FMD) seroprevalence and identify risk factors of exposure among cattle herds raised in three zones with different types of land use and progressively distant from the Maasai Mara National Reserve (MMNR) boundary. We selected five villages purposively; two in zone 1 (area < 20 km from the MMNR), another two in zone 2 (area between 20−40 km away from the MMNR) and one in zone 3 (area > 40 km away from the...
Abstract High risk human Papillomavirus (HPV) infections ultimately cause cervical cancer. Human Immunodefi ciency Virus (HIV) infected women often present with multiple high-risk HPV infections and are thus at a higher risk of developing cervical cancer. However, information on the circulating high-risk HPV genotypes in Kenya in both HIV-infected and HIV-uninfected women is still scanty. This study is aimed at determining the phylogeny and the HPV genotypes in women with respect to their H...
Abstract The prevalence of Human Herpes Virus type 8 (HHV-8), Human Immunodeficiency virus (HIV), and syphilis is high in Sub- Saharan Africa. Studies on HHV-8 in Kenya are few and data on its coinfection with HIV and syphilis scanty. This crosssectional study among female sex workers (FSWs) in Malindi, Kenya, aimed to determine the prevalence of HHV-8, HIV, and syphilis mono/coinfections and identify associated risk factors. A total of 268 FSWs consented and were administered a structured q...
Abstract Diabetes mellitus is a disease of antiquity with worrying global incidence and prevalence. Conventional management and/or treatment interventions have been hampered by drawbacks like high costs, inaccessibility, likelihood of potential adverse and toxic effects among others. Use of antidiabetic phytodrugs has been on the rise, particularly in the developing countries, perhaps due to cost implications and accessibility advantages. In this study, an aqueous leaf extract of the medicin...
Abstract OBJECTIVE: Developing countries are undergoing an epidemiologic transition accompanied by increasing burden of cardiovascular disease (CVD) linked to urbanization and lifestyle modifications. Metabolic syndrome is a cluster of CVD risk factors whose extent in Kenya remains unknown. The aim of this study was to determine the prevalence of metabolic syndrome and factors associated with its occurrence among an urban population in Kenya. RESEARCH DESIGN AND METHODS: This was a household...
Abstract There is limited data on comparative disposition to cervical cancer among HPV infected women in Kenya. We aimed to determine the distribution of HPV infection, cervical abnormalities and infections commonly reported on cervical pap smears among both HIV positive and HIV negative women attending a reproductive health clinic at the largest national hospital in Kenya. A total of 187 women aged 18 to 50 years attending the reproductive clinic at Kenyatta National Referral Hospital in Na...
Abstract Currently no published data addressing the burden of Human Immunodeficiency Virus (HIV) and Hepatitis B Virus (HBV) co-infection among injecting drug users (IDUs) in Kenya exists. These two viruses share similar routes of transmission, with illicit drug use by injection being the major route of infection. Injecting drug use is a rapidly growing problem in coastal towns of Kenya and the problem is aggravated by sex tourism.This study aimed at determining the prevalence of HBV in HIV ...
Abstract Abstract: Background: Malaria is one of the major causes of morbidity and mortality in Kenya. The diseases displays varying degrees of endemicity in different regions in the country, however the knowledge, attitudes and practices of communities about the disease prevention and control measures are in many cases not in tandem. Objective: To assess the level of knowledge, attitudes and practices of the communities towards malaria prevention and control options. Methodology: A cross se...
Abstract Salinity in the climate sensitive tropical endorheic crater lake Oloidien (Great African Rift Valley, Kenya) decreased from hyposaline to subsaline conditions during the period 2010–2015. The change in salinity was accompanied by a pronounced change in planktonic life forms—from blooms of the cyanobacterium Arthrospira supporting tens of thousands of Lesser Flamingos to highly diverse communities of cyanobacteria and algae which do not sustain the consumer birds. Besides the wel...
Abstract Background Information about HBV sero-markers, infection stages and genotypes in HIV-1 infected and uninfected injection and non-injection drug users (IDUs) in Kenya remains elusive. Methods A cross-sectional study examining HBV sero-marker, infection stages and genotypes was conducted among HIV-1 infected and uninfected, respectively, IDUs (n = 157 and n = 214) and non-IDUs (n = 139 and n = 48), and HIV-1 uninfected non-drug using controls (n = 194) from coastal...
Abstract Background: Anopheles gambiae is the main carrier for parasites that cause malaria and filariasis as well as viruses that cause yellow fever, dengue fever, dengue haemorrhagic fever, chikungunya and encephalitis. Culex quinqefasciatus on the other hand is the main vector for parasites that cause filariasis and the virus that cause encephalitis. Insecticide use to control these vectors has led to the development of mosquito resistance, environmental pollution, and undesirable effects...
