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...
Abstract Mycobacterium tuberculosis, a Gram-positive bacterium of great clinical relevance, is a lethal pathogen owing to its complex physiological characteristics and development of drug resistance. Several molecular genetic tools have been developed in the past few decades to study this microorganism. These tools have been instrumental in understanding how M. tuberculosis became a successful pathogen. Advanced molecular genetic tools have played a significant role in exploring the complex ...
Abstract Covid-19 was first reported in Wuhan China but has now spread globally with overwhelming impacts on human health and health systems. The disease is caused by the SARs-Cov-2 which is related to the SARs-Cov-1 that causes SARs. There is evidence suggesting that the virus originated from the Rhinolophilid bats and has subsequently undergone recombination to allow for a natural selection for a human host and it is thought that the recombination might have occurred either prior or upon i...
Abstract Background: We implemented a longitudinal study to determine the incidence of Brucella infection in cattle, camels, sheep and goats that were being raised in a pastoral area in Isiolo County, Kenya. An initial cross-sectional survey was implemented to identify unexposed animals for follow up; that survey used 141 camels, 216 cattle, 208 sheep and 161 goats. Sera from these animals were screened for Brucella spp. using the Rose Bengal Plate test (RBPT), a modiied RBPT, and an indirec...
Abstract Zoonotic diseases, such as brucellosis, Q fever and Rift Valley fever (RVF) caused by Brucella spp., Coxiella burnetii and RVF virus, respectively, can have devastating effects on human, livestock, and wildlife health and cause economic hardship due to morbidity and mortality in livestock. Coinfection with multiple pathogens can lead to more severe disease outcomes and altered transmission dynamics. These three pathogens can alter host immune responses likely leading to increased mo...
Abstract Brucellosis, caused by several species of the genus Brucella, is a zoonotic disease that afects humans and animal species worldwide. Information on the Brucella species circulating in diferent hosts in Kenya is largely unknown, thus limiting the adoption of targeted control strategies. This study was conducted in multi‑host livestock populations in Kenya to detect the circulating Brucella species and assess evidence of host–pathogen associations. Serum samples were collected fro...
Abstract/Overview This paper critically reviews the outcomes of internationally-funded interventions aimed at climate change adaptation and vulnerability reduction. It highlights how some interventions inadvertently reinforce, redistribute or create new sources of vulnerability. Four mechanisms drive these maladaptive outcomes: (i)shallow understanding of the vulnerability context; (ii) inequitable stakeholder participationin both design and implementation; (iii) a retrofitting of adaptat...
Abstract/Overview Substance and drug use is one of the emerging public health problems among the youth in Kenya. Moreover, it is associated with a myriad of medical effects including psychiatric problems, organ failures in addition to lethargy, decreased academic performance and risk of contracting sexually transmitted infections. Although substance and drug use has been associated with these problems, the magnitude of substance and drug use and its predictors has not been investigated in...
