Prevalence of constipation among children referred to gastroenterology clinic with chronic abdominal pain at Kenyatta National Hospital
Background: Chronic abdominal pain is one of the most common presenting complaints to primary care providers and paediatricians. Studies in developed countries have shown that constipation is one of the most common diagnoses in children presenting with chronic abdominal pain.Objectives: To determine the prevalence of constipation in children 4-13 years presenting with chronic abdominal pain and to describe the pharmacological and non-pharmacological management of children with constipation at Kenyatta National Hospital.Design: A cross-sectional hospital based study.Setting: Paediatric Gastroenterology Clinic, Kenyatta National Hospital.Subjects: children aged 4 to 13 years attending the paediatric gastroenterology clinic at Kenyatta National Hospital between July to December 2014.Results: A total of 84 children with chronic abdominal pain were seen, 47 (55.95%) were girls and the median age was nine years. The prevalence of constipation in children with chronic abdominal pain with two or more Rome III criteria was 69 out of 84 (82%, 95%CI: 72%95%), out of which there were 37(53.62%) females and 32(46.3%) males. The difference among the boys and girls was not statistically significant. Pharmacological management was more commonly used than non-pharmacological management. The most common medication given to children with constipation was lactulose given to 63 (91.3%) of the children. The non-pharmacological management of constipation was education and dietary advice 53(76.8%), while behaviour change advice was given to 28 (40.6 %).Conclusion: The prevalence of constipation in children with chronic abdominal pain was 82%. Pharmacological management was more commonly used than non pharmacological
Chronic Ileocecal Intussusception Secondary to Non-Hodgkins Lymphoma
Chronic intussusception is a distinct clinical entity which is unfortunately poorly recognized due to its atypical presentation. A 5½ year old female patient presented with a 5 month history of abdominal pain associated with occasional vomiting, anorexia and progressive weight loss. 5 days prior to admission she developed loose, non-mucoid, non-blood stained stool associated with refusal to feed and irritability. Systemic examination, an abdominal ultrasound and abdominal radiograph were non-contributory.During treatment for malnutrition and dehydration she was noted to clinically improve, however, 6 days post-admission she developed abdominal pain, a palpable sausage-shaped abdominal mass, and currant-jelly stool. Emergency laparotomy revealed an ileocecal intussusception with oedematous nonviable, aperistaltic terminal ileum and mobile cecum, a cecal mass and mesenteric lymphadenopathy was found. We performed a right hemicolectomy with an ileocolic anastomosis and mesenteric lymph node sampling. Histology results revealed the cecal mass as a lymphoproliferative neoplasm with a diagnostic consideration of intermediate to large cell Non-Hodgkins Lymphoma; and reactive hyperplasia of mesenteric lymph nodes. There is need for a highindex of suspicion in children with non-specific abdominal symptoms for which no cause can be found. Further, all suspicious masses should haveimmunohistological histological evaluation.Key Words: Chronic Ileocecal Intussusception, Non Hodgkins Lymphom
Language Attitudes and Kiswahili Language Learning in Primary Schools in Kenya
Kiswahili and English are two important languages taught and examined at the national level in Kenya’s education system. Students’ academic performance in the subjects keeps varying in national examinations. Different from English, however, poor performance in Kiswahili is more often associated with negative attitudes. Nevertheless, empirical validations have in most cases, not been established. The present study explores pupils’ attitudes toward Kiswahili in the context of second language learning in Siaya County of Kenya. The study is anchored on the assumption that although language attitudes play a big role in second language learning and development, primary school pupils have often been neglected in the investigation of language attitudes despite the fact that Kiswahili language learning and teaching begins at that level. A sample size of 360 class eight pupils randomly picked from 18 primary schools of Siaya County participated in the survey. Data collection was by use of attitude questionnaires and, analysed by mixed method approach.  Results showed that primary school pupils had positive attitudes towards Kiswahili. The attitudes were due to the communicative and integrative functions of Kiswahili. Pupils however indicated that English remained instrumental to their academic and future pursuits.  Consequently, Kiswahili was not accorded the same weight as English, which in turn influenced negatively Kiswahili language learning. The study calls for creation of awareness about the instrumental value of Kiswahili language to learners. This be done, from the early stages of their academic development. Moreover, it recommends that the culture of using grammatical language by learners be encouraged, as much as it is possible.  This will serve to improve their Kiswahili language skills and contribute to good performance.

Genotyping for point mutations in selected codons of pfcrt and pfmdr-1 genes of Plasmodium falciparum among patients with uncomplicated malaria in Mbita district Kenya.
Background Malaria remains a leading cause of morbidity and mortality in Kenya, especially in young children and pregnant women. Due to widespread resistance of Plasmodium falciparum to drugs such as Chloroquine (CQ) and Sulfurdoxine-Pyrthamine (SP), Artemisisnin Combination Therapy (ACT) was adopted in Africa as a means of improving treatment efficacy and slowing the spread of resistance. The development of drug resistance by the parasites for the various malaria drug regimens that have been in use before has been attributed to point mutations within the parasite genome. Therefore this study investigated the prevalence of point mutations in selected codons of the pfcrt and pfmdr-1 genes of Plasmodium falciparum. It is however unclear whether ACT will be effective in preventing the selection of resistant parasites in Africa, where parasite transmission rates are generally much higher with parts of Asia and Africa already reporting a reduction in sensitivity to ACT. Methods The dot-blot/probe hybridization technique was used to identify point mutations in codons 74, 75 and 76 of the pfcrt gene and codons 1034, 1042 and 1246 of the pfmdr-1 gene in Mbita a malaria holoendemic site in Kenya. In the pfcrt gene, 76T mutation was found to be in 91 (79.83% CI 63.1-88.5) of 114 samples while the, the wild type allele 76K was present in 23 (20.17% CI 9.0-22.0) samples. Codons 1246 showed allelic variation with 1246D the wild type allele being 72.8% (CI 52.0-89.1). This was a significant increase in the 76K allele (p=0.001) in comparison to the year 2005 where prevalence of 76K was 6%.  Conclusion There’s an expansion of the wild-type allele 76K of the pfcrt gene and no significant difference in the 1246D allele of the pfmdr1 gene, moreover the prevalence of 76T allele is still high in Mbita hence it’s beneficial to continue using AL as treatment for uncomplicated malaria.

Investigating the dynamics of resilience and greenhouse gas performance of pastoral cattle systems in southern Ethiopia
Context: Pastoral and agro-pastoral (PAP) systems in East Africa face a range of challenges including increased climate variability. Various measures have been proposed to improve the resilience of pastoral/agro-pastoral (PAP) systems to drought. However, identifying the most effective measure for a given system and location is complicated, and tools are required to appraise measures on a consistent basis.Objective: This paper develops a model of a PAP system and uses it to assess the effects of four measures (Index-based livestock insurance, IBLI; Commercial destocking with an early warning system, EWS; Rangeland restoration, RR; Fodder planting, FP) on the resilience of the PAP system. It also quantifies the greenhouse gas (GHG) effects of the measures, thereby identifying potential trade-offs and synergies between the policy objectives of resilience and climate smart agriculture (CSA).Methods: A dynamic model of the Borena pastoral cattle system was developed to undertake the analysis. At its core is a herd model that calculates the changes in cattle population over time. Feed availability and drought occurrence affect fertility and mortality rates, which in turn determine the population and (meat and milk) production. A suite of indicators covering the three dimensions of CSA (increasing productivity, enhancing resilience and reducing GHG emissions) were developed, and used to compare the situation with and without measures.Results and discussions: Destocking with an early warning system provides the biggest increases (relative to the no measure situation) in production and profit, due to the way it changes the herd size and structure. It maintains a larger herd than any of the other measures, and a greater proportion of the herd are adult females. Fodder planting and rangeland restoration provide moderate increases in production and profit. Index-based livestock insurance provides a moderate increase in protein production, but has no effect on profit, as it is designed to reduce risk rather than increase productivity or profit, at least in the short term.All of the measures increase the total emissions relative to the no measure scenario. In terms of the three dimensions of climate-smart agriculture, IBLI leads to some improvements in productivity and resilience but leads to large increases in total emissions, and modest increases in emissions intensity (EI). EWS leads to large increases in productivity and resilience. However, it also leads to large increases in total emissions and a mixed effect on EI. FP and RR improve productivity and increase total emissions, while having little effect on EI or resilience.Significance: This paper illustrates the way in which systems dynamic model can be used to appraise measures designed to improve resilience. The result identify potential synergies and tensions between the goals of resilience and climate smart agriculture, and raises the question of whether fully climate-smart goals are viable in these systems
Medication diaries do not improve outcomes with highly active antiretroviral therapy in Kenyan children: a randomized clinical trial
<p>Abstract</p> <p>Background</p> <p>As highly active antiretroviral therapy (HAART) becomes increasingly available to African children, it is important to evaluate simple and feasible methods of improving adherence in order to maximize benefits of therapy.</p> <p>Methods</p> <p>HIV-1-infected children initiating World Health Organization non-nucleoside reverse transcriptase-inhibitor-containing first-line HAART regimens were randomized to use medication diaries plus counselling, or counselling only (the control arm of the study). The diaries were completed daily by caregivers of children randomized to the diary and counselling arm for nine months. HIV-1 RNA, CD4+ T cell count, and z-scores for weight-for-age, height-for-age and weight-for-height were measured at a baseline and every three to six months. Self-reported adherence was assessed by questionnaires for nine months.</p> <p>Results</p> <p>Ninety HIV-1-infected children initiated HAART, and were followed for a median of 15 months (interquartile range: 2–21). Mean CD4 percentage was 17.2% in the diary arm versus 16.3% in the control arm at six months (p = 0.92), and 17.6% versus 18.9% at 15 months (p = 0.36). Virologic response with HIV-1 RNA of <100 copies/ml at nine months was similar between the two arms (50% for the diary arm and 36% for the control, p = 0.83). The weight-for-age, height-for-age and weight-for-height at three, nine and 15 months after HAART initiation were similar between arms. A trend towards lower self-reported adherence was observed in the diary versus the control arm (85% versus 92%, p = 0.08).</p> <p>Conclusion</p> <p>Medication diaries did not improve clinical and virologic response to HAART over a 15-month period. Children had good adherence and clinical response without additional interventions. This suggests that paediatric HAART with conventional counselling can be a successful approach. Further studies on targeted approaches for non-adherent children will be important.</p
Association between thrombocytes count and Plasmodium falcipurum infection among children under five years attending Kombewa Sub-County Hospital
Malaria is a leading cause of morbidity and mortality especially among children, expectant women and continues to be a global health burden. Haematological changes mark some of the most common complications in malaria as they play a major role in malaria pathology. Thrombocytes in particular, have been shown to bind infected erythrocytes and kill intracellular malaria parasites thereby indicating a protective function of platelets in the early stages. However, the mechanism that leads to low thrombocytes count in malaria infected individuals is not clear. Understanding the mechanism of platelet reduction during pathogenesis of malaria infection will be fundamental in malaria severity classification, monitoring of platelet count during infection and prompt initiation of anti-malarial therapy. In trying to understand these facts, this study sort to establish the association between platelet count and P. falciparum infection amongst children less than five years. This was a retrospective case-control study, n=549. Children below the age of five years that attending Kombewa Sub -County Hospital were recruited. Study participants were identified using the inclusion criteria and followed horizontally to retrieve platelet count from complete blood count results. The respective malaria blood film reads were then recorded, stratified to give case and control from which random sampling was done. Chi-square test and Tukey’s multiple comparison tests from Graph pad prism 5 were used in the analysis. The odds of exposure to low platelet count were then established with a confidence level of 95%. We found significant difference between the cases and controls in regard to parasite density (Chi square=157.5, p value <0.05), mean parasite density in controls =2042.1/?l compared to cases= 142880/?l. The odds of cases being exposed to malaria was 12 times more than controls (OR=12.382, 95%). We also found no variation in thrombocytes counts in relation to gender, children with thrombocytopenia were having higher parasite density, parasite density as a result of P.falciparum infection is not dependent on gender and children that suffered malarial infection were twelve times likely to develop thrombocytopenia. Further studies are then recommended to establish the effects of incorporation of platelet aggregation inhibitors such as aspirin in malaria treatment.Key Words: Plasmodium falciparum, thrombocytopenia, infectio
Evaluation of a two-way SMS messaging strategy to reduce neonatal mortality: rationale, design and methods of the Mobile WACh NEO randomised controlled trial in Kenya
Abstract: Introduction Globally, approximately half of the estimated 6.3 million under-5 deaths occur in the neonatal period (within the first 28 days of life). Kenya ranks among countries with the highest number of neonatal deaths, at 20 per 1000 live births. Improved identification and management of neonates with potentially life-threatening illness is critical to meet the WHO’s target of ≤12 neonatal deaths per 1000 live births by 2035. We developed an interactive (two-way) short messaging service (SMS) communication intervention, Mobile Solutions for Neonatal Health (Mobile women’s and children’s health (WACh) NEO), focused on the perinatal period. Mobile WACh NEO sends automated tailored SMS messages to mothers during pregnancy and up to 6 weeks post partum. Messages employ the Information-Motivation-Behaviour Skills framework to promote (1) maternal implementation of essential newborn care (ENC, including early, exclusive breast feeding, cord care and thermal care), (2) maternal identification of neonatal danger signs and care-seeking, and (3) maternal social support and self-efficacy. Participants can also send SMS to the study nurse, enabling on-demand remote support.
Methods and analysis We describe a two-arm unblinded randomised controlled trial of the Mobile WACh NEO intervention. We will enrol 5000 pregnant women in the third trimester of pregnancy at 4 facilities in Kenya and randomise them 1:1 to receive interactive SMS or no SMS (control), and conduct follow-up visits at 2 and 6 weeks post partum. Neonatal mortality will be compared between arms as the primary outcome. Secondary outcomes include care-seeking, practice of ENC and psychosocial health. Exploratory analysis will investigate associations between maternal mental health, practice of ENC, care-seeking and SMS engagement.
Ethics and dissemination This study received ethical approval from the University of Washington (STUDY00006395), Women and Infants Hospital (1755292-1) and Kenyatta National Hospital/University of Nairobi (P310/04/2019). All participants will provide written informed consent. Findings will be published in peer-reviewed journals and international conferences
Comparison of least absolute shrinkage and selection operator and maximum likelihood estimators to establish determinants of immunization in Trans - Nzoia County
The client factors that influence under-five child guardian compliance to the immunization schedule are interlinked based on household characteristics,
socioeconomic status, and maternal health practices. An incentive to motivate the mothers to prioritize their child’s health practices especially on vaccination, works perfectly towards the achievement of full immunization
coverage. A randomly sampled study carried out within Weonia Location–Trans Nzoia County in March 2014 with target population of under-five children showed the vital role an incentive innovation plays towards immunization coverage. Multinomial logistic regression model was used to analyze the determinant of partial or none-immunized and the parameters estimated using the maximum likelihood estimator (MLE) and the shrinkage estimator-Least Absolute Shrinkage and Selection Operator (LASSO). The
shrinkage estimator method gave a sparse model that was easy to interpret and increased the estimated predictability accuracy. Maternal health practices and access to a motivating intervention are significant factors that ensure a guardian’s compliance to their child immunization
