Quality of glycaemic control in ambulatory diabetics at the out-patient clinic of Kenyatta National Hospital, Nairobi

Background: Treatment of diabetes mellitus is based on the evidence that lowering blood glucose as close to normal range as possible is a primary strategy for reducing or preventing complications or early mortality from diabetes. This suggests poorer glycaemic control would be associated with excess of diabetes-related morbidity and mortality. This presumption is suspected to reach high proportions in developing countries where endemic poverty abets poor glycaemic control. There is no study published on Kenyan patients with diabetes mellitus about their glycaemic control as an audit of diabetes care. Objective: To determine the glycaemic control of ambulatory diabetic patients. Design: Cross-sectional study on each clinic day of a randomly selected sample of both type I and 2 diabetic patients. Setting: Kenyatta National Hospital. Methods: Over a period of six months, January 1998 to June 1998. During routine diabetes care in the clinic, mid morning random blood sugar and glycated haemoglobin (HbAI c)were obtained. Results: A total of 305 diabetic patients were included, 52.8% were females and 47.2% were males. 58.3% were on Oral Hypoglycaemic Agent (OHA) only, 22.3% on insulin only; 9.2% on OHA and insulin and 4.6% on diet only. 39.5% had mean HbAlc £ 8% while 60.5% had HbAlc ³ 8%. Patients on diet-only therapy had the best mean HbAlc=7.04% while patients on OHA-only had the worst mean HbAlc=9.06%. This difference was significant (p=0.01). The former group, likely, had better endogenous insulin production. The influence of age, gender and duration of diabetes on the level of glycaemic control observed did not attain statistically significant proportions. Conclusion: The majority of ambulatory diabetic patients attending the out-patient diabetic clinic had poor glycaemic control. The group with the poorest level of glycaemic control were on OHA-only, while best control was observed amongst patients on diet-only, because of possible fair endogenous insulin production. Poor glycaemic control was presumed to be due to sub-optimal medication and deteriorating diabetes. There is need to empower patients with knowledge and resources to enhance their individual participation in diabetes self-care. Diabetes care providers and facilities also need capacity building to improve care of patients with diabetes. East African Medical Journal Vol.80(8) 2003: 406-41

Cost-efficient evaluation of ambulance services for community critical care transport needs in Machakos County, Kenya

Background: Machakos County is one of the 47 counties in Kenya. In the current study performance of ambulance services were measured using indicators such as response time, on-scene time, clients’ satisfaction and cost-efficiency (technical).Objectives: To determine the cost-efficient ambulance services appropriate for community critical care transport needs in Machakos County.Design: Descriptive cross sectional study.Setting: Machakos County (Emergencies Services Department)Subjects: Publically financed ambulancesResults: Machakos has seventy Basic Life Support (BLS) ambulances distributed among the 69 administrative locations (wards). A total of 12,674 victims were transported to different tares of hospital and referrals between March 2014 to May 2015. Victims requiring emergency obstetric care (EMOC) accounted for 24.7% of victims transported, road traffic accidents victims10.3% and the least were rape victims at 0.03%. The annual operational cost was Kshs. 70,328,627 (USD 717,639.05). Expenditure profiles indicated that staff wages accounted for 49% of total operational cost,overheads costs accounted for 33.5%, while office rent accounted for 1.36%. The mean unit cost per kilometer was Kshs. 30.9 (USD 0.32) and cost per victim transported by an ambulance was Kshs. 6,504 (USD 66.37). Key demand factors were social cultural and health seeking behaviours of residents. The supply barriers were transport costs, operational costs and in-efficient signage on roads for direction. The mean cost-efficiency (technical) of Machakos ambulance transport services was 90.6% (C.I 82.7% - 98.2%).Conclusion: Machakos County Government ambulance services was technically efficient operating

Determination of Caffeine Content in Non-Alcoholic Beverages and Energy Drinks Using Hplc-Uv Method.

The purpose of this study was to determine the amount of caffeine in non-alcoholic energy drinks and prepared teas using reverse phase HPLC. Caffeine was extracted from 19 different types of non-alcoholic beverages and prepared teas sampled from supermarkets in Nairobi Central Business District, Kenya. These were analyzed alongside a caffeine standard of 99 % purity by use of HPLC-UV detector at the wavelength of 272nm, Supelco HS C18 column 25 cm x 4.6 cm x 5 μm, oven temperature of 40 oC, mobile phase 80:20 (v/v) of methanol: water and mobile phase flow rate of 1.5mL/min. For quantitation purposes, serial dilution of the caffeine standard gave correlation coefficient (r) of 0.9993 and the retention time of 2.11±0.03 minute. Percentage recovery of caffeine from the column ranged from 89.78 to 105.59%. Limits of detection and quantitation were found to be 0.279 and 0.931 μg/mL respectively. It was found that Burn®, XL energy drink® and Red Bull® had the highest amount of caffeine. It was however noted that though most of the non-alcoholic beverages had high caffeine content they had no label claim. Key Words: Reverse Phase High Performance Liquid chromatography (HPLC), Ultra violet visible (UV/VIS), caffeine, non-alcoholic beverage

The birds of Uaso Narok Forest Reserve, Central Kenya

The birds of the Uaso Narok Forest, Central Kenya, were surveyed between June 2008 and April 2009. We recorded 161 species representing 49 families in total. Of these species, 34 were representative of the Afrotropical Highland Biome, representing 51% of all Kenyan species of this biome; two species were representative of the Somali-Masai biome. In addition to the Lesser Kestrel Falco naumanni (listed as Vulnerable in the IUCN Red List), there were 27 species of regional conservation concern. Breeding activity was recorded for 39 species, while a new population of Black-billed Weaver Ploceus melanogaster was discovered here, thus extending the species’ known range. The main human activities recorded in this forest included firewood collection, illegal logging and charcoal burning. This survey revealed that Uaso Narok Forest is important for the conservation of Kenya’s montane forest avifauna and deserves immediate official protection, as well as further biological research

Regional Initiatives in Support of Surveillance in East Africa: The East Africa Integrated Disease Surveillance Network (EAIDSNet) Experience.

The East African Integrated Disease Surveillance Network (EAIDSNet) was formed in response to a growing frequency of cross-border malaria outbreaks in the 1990s and a growing recognition that fragmented disease interventions, coupled with weak laboratory capacity, were making it difficult to respond in a timely manner to the outbreaks of malaria and other infectious diseases. The East Africa Community (EAC) partner states, with financial support from the Rockefeller Foundation, established EAIDSNet in 2000 to develop and strengthen the communication channels necessary for integrated cross-border disease surveillance and control efforts. The objective of this paper is to review the regional EAIDSNet initiative and highlight achievements and challenges in its implementation. Major accomplishments of EAIDSNet include influencing the establishment of a Department of Health within the EAC Secretariat to support a regional health agenda; successfully completing a regional field simulation exercise in pandemic influenza preparedness; and piloting a web-based portal for linking animal and human health disease surveillance. The strategic direction of EAIDSNet was shaped, in part, by lessons learned following a visit to the more established Mekong Basin Disease Surveillance (MBDS) regional network. Looking to the future, EAIDSNet is collaborating with the East, Central and Southern Africa Health Community (ECSA-HC), EAC partner states, and the World Health Organization to implement the World Bank-funded East Africa Public Health Laboratory Networking Project (EAPHLNP). The network has also begun lobbying East African countries for funding to support EAIDSNet activities

High prevalence of <i>Rickettsia africae</i> variants in <i>Amblyomma variegatum</i> ticks from domestic mammals in rural western Kenya: implications for human health

Tick-borne spotted fever group (SFG) rickettsioses are emerging human diseases caused by obligate intracellular Gram-negative bacteria of the genus Rickettsia. Despite being important causes of systemic febrile illnesses in travelers returning from sub-Saharan Africa, little is known about the reservoir hosts of these pathogens. We conducted surveys for rickettsiae in domestic animals and ticks in a rural setting in western Kenya. Of the 100 serum specimens tested from each species of domestic ruminant 43% of goats, 23% of sheep, and 1% of cattle had immunoglobulin G (IgG) antibodies to the SFG rickettsiae. None of these sera were positive for IgG against typhus group rickettsiae. We detected Rickettsia africae–genotype DNA in 92.6% of adult Amblyomma variegatum ticks collected from domestic ruminants, but found no evidence of the pathogen in blood specimens from cattle, goats, or sheep. Sequencing of a subset of 21 rickettsia-positive ticks revealed R. africae variants in 95.2% (20/21) of ticks tested. Our findings show a high prevalence of R. africae variants in A. variegatum ticks in western Kenya, which may represent a low disease risk for humans. This may provide a possible explanation for the lack of African tick-bite fever cases among febrile patients in Kenya

Nutritional Status of Adolescent and Adult PLWHA on Anti-Retroviral Treatment, Attending Various Comprehensive Care Centres in Nairobi County, Kenya

Background: Maintaining nutritional needs of People Living with HIV and AIDS (PLWHA) who are on Anti-Retroviral Treatment (ART) helps to strengthen their immune system and optimize response to medical treatment. The main objective of this study was to assess the nutritional status PLWHA on ART and the associated factors. Methodology: This was a cross-sectional study where 454 adolescent and adult PLWHA on ART were randomly selected and consent obtained to join the study. Structured interviewer-administered questionnaires were used to gather data on their socio-economic characteristics, the types of food consumed in the last 24 hours and their Body Mass Index. The data was organized and analysed using SPSS version 17.0. Variables were categorized and Chi-square statistical test used to assess association where a p-value of less than or equal to 0.05 was considered statistically significant. Results: A total of 454 PLWHA were recruited into the study and 180 (39.6%) were males while 274 (60.4%) were females giving a Male: Female ratio of 1: 1.5. Over three quarters (77%) had attained secondary education and above. The main sources of income were employment (48.5%) and business (44.9%). The types of foods consumed were beans and beef for body building (proteins); Ugali (maize meal) and rice for energy (Carbohydrates); kales and cabbages (vegetables), bananas and pineapples (fruits) as protective foods. Over half (51.1%) were overweight/obese. Sources of income and the monthly earnings were significantly associated with the overweight/obesity. Conclusion: The PLWHAs’ sources of income and monthly earnings had statistical significance on their nutritional status (BMI) of being over-weight/obese. However, other factors such as: ART’s ability to decrease resting-energy expenditure and basal metabolic rate resulting in replenishment of muscle bulk and hence weight gain; or intentional over-eating to avoid the stigmatized weight loss which is often “associated” with being HIV positive may have had a part to play. Keywords: PLWHA; ART; Nutritional status (BMI); food groups and consumption; food availability, affordability and use

Intermittent preventive treatment and bed nets uptake among pregnant women in Kenya

Background: Malaria in pregnancy is a preventable disease which results in poor pregnancy outcomes. The use of intermittent preventive treatment in pregnancy (IPTp) and long-lasting insecticide treated nets (LLINs) have been shown to reduce maternal malaria episodes.Objectives: To describe i) The proportion receiving first and second dose (IPTp1 and 2) in malaria endemic zones, ii) proportion receiving IPTp 1 and 2 stratified by coast and lake endemic zones iii) proportion receiving LLINs, stratified by coastal and lake endemic zones.Design: A retrospective descriptive study.Setting: Lake and Coast region malaria endemic zones.Subjects: Pregnant women.Results: IPTp2 dose during an ANC revisit fell by 29% between 2012 and 2015, with 76% receiving an IPTp2 in 2012 and only 47% receiving it in 2015. More pregnant women in Coastal endemic areas received IPTp2 compared to Lake, with 88% versus 73% in 2012, and 53% versus 44% in 2015, respectively.There was steady increase in bed net usage from 69% and 54% in 2012 to 96% and 95% in 2015 for lake and coast endemic zones respectively. The uptake of LLINs was 15% higher in the lake region compared to the coastal endemic region in 2012 and significantly declined over the five years to 6%, 7% and 1% in 2013, 2014 and 2015, respectively.Conclusion: Our study found that there has been a significant decline from 2012 through 2015, in the number of pregnant women in Kenya receiving recommended malaria prophylaxis in the regions of highest malaria burden. However, the coverage of LLIN has consistently improved over the same period

Adherence to Anti-Retroviral Treatment and Factors Associated with Optimal Adherence among Adolescent and Adult PLWHA Attending Comprehensive Care Centres in Selected Hospitals in Nairobi County

Background: Anti-retroviral therapy (ART) has saved many lives from imminent deaths among PLWHA. However, the success is pegged on optimal (&gt;95%) adherence to the ART by the PLWHA. The main objective of this study was to determine the ART adherence level by the PLWHA and the factors associated with the adherence.Methods: This was a cross sectional descriptive study on 454 PLWHA, attending Comprehensive Care Centres (CCCs) in selected hospitals in Nairobi County. A structured questionnaire was used to collect data. The Data was analysed using SPSS version 17.0. Results: There were 180 (39.6%) males and 274 (60.4%) females in the study. Majority (53.3%) PLWHA were aged between 40 and 49 years. Only 265 (58.4%) had optimal adherence to ART and duration on the ART was found to be significantly associated with optimal adherence to ART drugs.Conclusion: Optimal adherence was far below the recommended (&gt;95%) mark and duration on  ART was found to be significantly associated with optimal adherence. That is, the shorter the time one had been on ART, the more the chances of being more adherent. Most PLWHA blamed forgetfulness as the main reason for their failure to take the ART drugs as required. Since Anti-Retroviral Treatment is a lifelong process, targeted counselling including reminders (ringing of a bell in the phone) and formation of groups for calling each other for remembrance would suffice.
