Sternal cleft is a rare congenital anomaly and very few cases have been described especially in Africa. This is a case of an isolated superior sternal cleft in a term neonate in Western Kenya
Primacy of effective communication and its influence on adherence to artemether-lumefantrine treatment for children under five years of age: a qualitative study.
BACKGROUND\ud
\ud
Prompt access to artemesinin-combination therapy (ACT) is not adequate unless the drug is taken according to treatment guidelines. Adherence to the treatment schedule is important to preserve efficacy of the drug. Although some community based studies have reported fairly high levels of adherence, data on factors influencing adherence to artemether-lumefantrine (AL) treatment schedule remain inadequate. This study was carried-out to explore the provider's instructions to caretakers, caretakers' understanding of the instructions and how that understanding was likely to influence their practice with regard to adhering to AL treatment schedule.\ud
\ud
METHODS\ud
\ud
A qualitative study was conducted in five villages in Kilosa district, Tanzania. In-depth interviews were held with providers that included prescribers and dispensers; and caretakers whose children had just received AL treatment. Information was collected on providers' instructions to caretakers regarding dose timing and how to administer AL; and caretakers' understanding of providers' instructions.\ud
\ud
RESULTS\ud
\ud
Mismatch was found on providers' instructions as regards to dose timing. Some providers' (dogmatists) instructions were based on strict hourly schedule (conventional) which was likely to lead to administering some doses in awkward hours and completing treatment several hours before the scheduled time. Other providers (pragmatists) based their instruction on the existing circumstances (contextual) which was likely to lead to delays in administering the initial dose with serious treatment outcomes. Findings suggest that, the national treatment guidelines do not provide explicit information on how to address the various scenarios found in the field. A communication gap was also noted in which some important instructions on how to administer the doses were sometimes not provided or were given with false reasons.\ud
\ud
CONCLUSIONS\ud
\ud
There is need for a review of the national malaria treatment guidelines to address local context. In the review, emphasis should be put on on-the-job training to address practical problems faced by providers in the course of their work. Further research is needed to determine the implication of completing AL treatment prior to scheduled time
Higgs Production and at a Future Muon-Ion Collider
We investigate the production of Higgs bosons in neutral- and charged-current
interactions at a future Muon-Ion Collider (MuIC) with emphasis on decay. In particular, we focus on the leading production
mechanisms and explore the impact of a range of Parton Distribution Function
(PDF) scenarios, with emphasis on the role of heavy intrinsic quark flavor. We
emphasize estimates of non-resonant di-charm background production and explore
the impact of this background on a possible future measurement of at a future Muon-Ion Collider facility.Comment: 40 pages,38 figure

The role of networks in opportunity identification: a focus on African transnational entrepreneurs
There is a growing body of work which highlights the importance of Transnational Entrepreneurs (TEs) as catalysts for economic development in both their home and host countries. However, their opportunity identification predispositions are less understood. Thus, this study explores the nature and practices of TEs of African origin and it also focuses on how they identify viable business opportunities in their host countries. In addition, the study defines the role networks play in assisting them to achieve their business objectives. Through its application of social network constructs for data collection and analysis, this study contributes to the ongoing discourse on TEs. Specifically, it provides new insights into the way TEs of African origin living in the UK identify and exploit business opportunities. Its key findings indicate that the human capital of TEs (in particular their host country work experience), active search, and their use of family and kinship networks underpins the way they identify opportunities in a foreign country. However, perhaps the most remarkable finding of this study is that, while TEs employ both formal and informal network ties in their host countries, they seem to rely exclusively on their informal networks in their home countries
Nutritional status of children admitted for diarrhoeal diseases in a referral hospital in western Kenya
Objectives: To determine the prevalence of malnutrition among children admitted with acute diarrhoea disease at Moi Teaching and Referral Hospital and to establish the effect of malnutrition on duration of hospital stay.
Design: Prospective observational study.
Setting: Paediatric wards of Moi Teaching and Referral Hospital, Eldoret, Kenya
Subjects: A total of 191 children aged 6 and 59 months admitted with acute diarrhoea disease, without chronic co-morbidities or visible severe malnutrition, were systematically enrolled into the study between November 2011 and March 2012.
Outcome Measures: Nutritional status based on WHO WHZ scores taken at admission and duration of hospital stay.
Results:The mean age was 13.2 months with a male to female sex ratio of 1.16:1. Of all the children seen with acute diarrhoeal diseases, 43.9% had acute malnutrition (
Conclusion: Routine anthrometry including weight for height identifies more children with malnutrition in acute diarrhoeal diseases. Presence of malnutrition did not affect duration of hospital stay
Malaria Parasitaemia among Febrile Children Infected with Human Immunodeficiency Virus in the Context of Prophylactic Cotrimoxazole as Standard of Care: A Cross- Sectional Survey in Western Kenya
Objective: To document the prevalence of malaria parasitaemia among the HIV infected febrile children in a malaria endemic area. Design: A cross-sectional study. Setting: An ambulatory paediatric HIV clinic in Western Kenya, between November 2011 and December 2012. Subjects: A total of 245 febrile HIV infected children aged less than 14 years attending the HIV clinic in the Webuye level IV hospital were included in the study. A systematic sampling method was used. Main outcomes: A blood sample was taken for malaria parasite testing. Presence or absence of malaria parasites was documented. Clinical and socio-demographic characteristics of the participants were also recorded. Results: A total of 245 participants were recruited mean age being 5.53 years. Malaria prevalence was 81.9%. Most participants (97%) were on cotrimoxazole prophylaxis. Some of the factors found to be positively associated with malaria parasitaemia were; male sex, care taker category (parent), WHO stage 3 and 4 of HIV disease, and a high absolute CD4 count. However, only the caretaker association was statistically significant. Conclusion: The frequency of malaria parasitaemia among febrile HIV infected children is still high regardless of the high cotrimoxazole prophylaxis uptake. It is also noted that there is a shift in the age group of fever among children toward the older age group. This implies that policies may need to be relooked at to include the older age group in the aggressive malaria prevention measures to avoid losing on the already made gains
Measuring Morbidity Associated with Urinary Schistosomiasis: Assessing Levels of Excreted Urine Albumin and Urinary Tract Pathologies
Urinary schistosomiasis is a debilitating disease caused by a parasitic worm that dwells in the blood vessels, particularly those surrounding the human bladder wall. Although not directly associated with high patient mortality, this disease is linked to both short-term morbidity, e.g. visible blood in urine (acute), as well as long-term sequelae, e.g. urinary tract pathologies (chronic). Numerous control programmes based upon chemotherapy have been implemented in sub-Saharan Africa in an attempt to reduce the burden of disease inflicted, particularly in children. Although there are rapid tests to assess the prevalence of acute manifestations of disease (i.e. blood in urine), namely urine-reagent strips, monitoring of chronic manifestations (i.e. urinary tract pathologies) is still rather laborious, time-consuming and requires specialised equipment, e.g. portable ultrasonography, as well as highly trained staff. This study has attempted to evaluate associations between albuminuria (albumin in urine, a new application for the HemoCue photometer) and urinary tract pathologies, and consequently assess this new biochemical marker as a potential rapid proxy of chronic disease sequelae typical in children in areas where urinary schistosomiasis is of public health importance
Industry expertise, information leakage, and the choice of M&A advisors
This paper examines the impacts of M&A advisors’ industry expertise on firms’ choice of advisors in mergers and acquisitions. We show that an investment bank's expertise in merger parties’ industries increases its likelihood of being chosen as an advisor, especially when the acquisition is more complex, and when a firm in M&A has less information about the merger counterparty. However, due to the concerns about information leakage to industry rivals through M&A advisors, acquirers are reluctant to share advisors with rival firms in the same industry, and they are more likely to switch to new advisors if their former advisors have advisory relationship with their industry rivals. In addition, we document that advisors with more industry expertise earn higher advisory fees and increase the likelihood of deal completion.Chang acknowledges financial support from Rega Capital Management Limited and Academic Research Fund Tier 1 provided by Ministry of Education (Singapore).

Precision Global Determination of the Decay Rate
We perform the first global fit to inclusive measurements
using a model-independent treatment of the nonperturbative -quark
distribution function, with next-to-next-to-leading logarithmic resummation and
fixed-order contributions. The normalization of the
decay rate, given by , is sensitive to physics beyond the Standard Model (SM). We
determine , in good
agreement with the SM prediction, and the -quark mass .
Our results suggest that the uncertainties in the extracted
rate have been underestimated by up to a factor of two, leaving more room for
beyond-SM contributions.Comment: 21 pages, 8 figure
A single FLOTAC is more sensitive than triplicate Kato-Katz for the diagnosis of low-intensity soil-transmitted helminth infections
Accurate diagnostic tools are pivotal for patient management and surveillance of helminth control programmes, particularly in the current era of preventive chemotherapy. Three consecutive stool samples were obtained from 279 schoolchildren from Zanzibar, an island where anthelminthic drugs have been administered on a large scale for more than a decade. All stool samples were examined with the Kato-Katz method. Additionally, one sample per child was preserved in sodium acetate-acetic acid-formalin solution, and examined with the FLOTAC technique. Considering the pooled results of both methods as diagnostic ‘gold' standard, the observed prevalences of Trichuris trichiura, hookworm and Ascaris lumbricoides were 63.4, 35.8 and 22.9%, respectively. The sensitivity of examining a single stool sample by FLOTAC for diagnosing T. trichiura, hookworm and A. lumbricoides was 88.7, 83.0 and 82.8%, respectively. Lower sensitivities were observed for Kato-Katz even after examining three stool samples: 71.8, 46.0 and 70.3%, respectively. Kato-Katz revealed considerably higher infection intensities than FLOTAC. The κ agreement between a single FLOTAC and triplicate Kato-Katz was 0.63 for diagnosing A. lumbricoides and 0.50 for T. trichiura, but only 0.30 for hookworm. The high sensitivity of FLOTAC holds promise for patient management, monitoring soil-transmitted helminth transmission and endpoint(s) of control at the population leve
