Short term survival of premature infants admitted to the new born unit at Moi Teaching and Referral Hospital, Kenya
Background: Short and long term survival rates of premature infants have been well documented in developed countries. However, there are few data in low resource settings describing the survival of preterm infants. Data on short term survival rates of preterm infants may inform clinicians in a resource limited setting when counseling families on expected outcomes of care.Objective: To determine survival to hospital discharge of preterm infants in a public tertiary hospital in Kenya.Design: Prospective hospital cohort study design was used.Setting: Moi Teaching and Referral Hospital New Born Unit, Kenya.Participants: Premature Infants and their mothersInterventions: No study specific interventions were performed. We prospectively evaluated survival from admission until discharge from the hospital of 175 premature infants admitted to the newborn unit at Moi Teaching and Referral Hospital, a tertiary public hospital, between December 2012 and August 2013. We determined the overall survival rate and gestational age and birth weight category survival rates.Main outcome measures and Analysis: Death or discharge was the main outcomes of interest. Cox Proportional Hazards model was used to determine factors associated with survival and Kaplan-Meier survival curves drawn.Results: Of the 175 infants, 53.1% were female, mean birth weight was 1342g (± 355.5) and 37% were born before arrival. There were 15.4% neonates born less than 28 weeks, 30.9% aged 28- 31 weeks and 53.7% above 32-37 weeks. The overall survival to hospital discharge was 60.6% (95% CI 0.53-0.68). The survival rate was 29.6% for infants born less than 28 weeks’ gestation, 50% for those born at 28-31 weeks and 75.5% for those born at or above 32 weeks. Gestation age of ≥ 32 weeks (HR 0.39, 95% CI 0.18-0.8), birth weight >1000g (HR 0.27, 95% CI 0.20-0.78) and maternal antenatal care attendance (HR 0.52, 95% CI 0.3-0.9) were associated with better survival. Caesarian section delivery was associated with increased risk of death (HR 4.26, 95% CI 1.88-9.66). Most of deaths (81%) occurred within the first seven days.Conclusions: Sixty percent of premature infants admitted to MTRH new born unit survived to hospital discharge. The survival limit defined as the gestation at which a prematurely born infant has a 50% chance of survival was at the gestational age category of 28-32 weeks
Adapting health behavior measurement tools for cross-cultural use
Background: Addressing health disparities in the global community requires awareness of how cultural differences in beliefs, traditions, norms, and values shape health problems and behaviors.
Review: This paper reviews methods of assessing health behaviors, how these assessments may be affected by cross-cultural differences, and methods of adaptation of health behaviors across cultures. We describe the methods used in appropriate translation processes and pilot-testing for health behavior assessment tools. We also discuss ways to limit literacy demands and incorporate qualitative interviews
Pediatric assent for a study of antiretroviral therapy dosing for children in western Kenya: a case study in international research collaboration
Multinational collaborators in health research face particular ethical challenges when conducting studies involving vulnerable populations such as children. We use an example from our first attempt to implement pediatric assent in the context of a longstanding research and clinical partnership between Kenyan and American medical schools to highlight the ethical and procedural issues related to pediatric assent that must be considered for multinational, pediatric studies. We consider relevant domestic, professional, and international guidelines for assent in pediatric research subjects, and we discuss the particular ethical challenges related to pediatric assent in the Kenyan context. Finally, we propose a way forward for approaching pediatric assent within our collaborative research program in Kenya that may apply to other multinational research partnerships.Fogarty International Center at the National Institutes of Health [R25TW006070];

Research Brief 08-02-HNP
Preliminary evidence suggests that improved nutrition early in human immunodeficiency virus (HIV) infection may delay progression to acquired immunodeficiency syndrome (AIDS) and delay the initiation or improve the effectiveness of antiretroviral drug therapy (ART). The scientific community has evolved in its appreciation of the value of food as an integral component of comprehensive care for individuals with HIV infection and AIDS. It is now well recognized that those who are food insecure and malnourished are more likely to fail drug treatment regimens. Body mass index (BMI) < 18 at the initiation of ART is strongly predictive of death. In addition, weight loss during the first four weeks of ART is also associated with death. A higher BMI is protective and is associated with better responses with ART. Patient response to nutrition intervention, however, may be confounded by the stage of HIV progression and other infections. That is, those who are in the earlier stages of the disease may respond better to aggressive nutrition intervention. The HIV Nutrition Project (HNP), "Increasing Animal Source Foods in Diets of HIV-infected Kenyan Women and Their Children," will evaluate the effect of protein quality and micronutrients found in meat on the health and nutritional well-being of women living with HIV in rural Kenya and the health and development of their children. By means of a randomized nutrition feeding intervention, researchers will study if the inclusion of meat added as an ingredient to a biscuit, when compared to soy or wheat, will best protect the immune system and prevent severe infection, prevent the loss of body mass and enhance the quality of life. These women are not yet receiving antiretroviral drugs and therefore not yet experiencing metabolic inefficiencies associated with AIDS.This publication was made possible through support provided by the Office of Agriculture, Bureau of Economic Growth, Agriculture and Trade, under Grant No. PCE-G-00-98-00036-00 to University of California, Davis.

Many of the 28 million people with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) estimated to be living in sub-Saharan Africa also suffer from malnutrition. Reproductive-aged women, their infants and young children are among the most vulnerable to malnutrition and progression of HIV to AIDS. As seen in eastern and southern Africa, mortality is increased in the malnourished. The HIV Nutrition Project (HNP) researchers will be evaluating the effect of protein quality and micronutrients found in meat on the health and nutritional well-being of women living with HIV in rural Kenya and the health and development of their children. By means of a randomized nutrition feeding intervention, the study will determine if meat in the diets of HIV-infected women and their children (1) protects the immune system and prevents severe infection, (2) prevents the loss of lean body mass, enhancing the quality of life among these drug naive women and enabling women to carry out their activities of daily living, and (3) supports the growth and development of their vulnerable children when compared to those given supplements with the same amount of energy, but with either soya or wheat protein. The intervention food with beef protein provides significantly more vitamin B12, lysine and bio-available iron and zinc when compared to the soya and wheat supplements. Deficiencies of these nutrients may hasten HIV disease progression.This publication was made possible through support provided by the Office of Agriculture, Bureau of Economic Growth, Agriculture and Trade, under Grant No. PCE-G-00-98-00036-00 to University of California, Davis.

In sub-Saharan Africa, an estimated 28 million people are living with the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). In 2001, Moi University in Eldoret, Kenya joined with Kenya’s second national referral hospital, Moi Teaching and Referral Hospital (MTRH) and Indiana University (IU) to establish the Academic Model Providing Access To Healthcare (AMPATH). AMPATH’s missions were to (1) provide high-quality patient care; (2) educate patients and health care providers; and (3) establish a laboratory for clinical research in HIV/AIDS (http://medicine.iupui.edu/kenya/hiv.aids.html). Leveraging the power of an academic medical partnership, AMPATH has quickly become one of the largest and most comprehensive HIV/AIDS control systems in sub-Saharan Africa, providing a comprehensive system of care that has been described as a model of sustainable development (Tobias, 2006). Delivery of services occurs in the public sector through hospitals and health centers run by Kenya’s Ministry of Health. AMPATH currently implements prevention activities that touch the lives of millions of persons in a wide geographic area. The research arm of AMPATH, created to facilitate and manage the international research agenda being generated by Kenyan and US faculty, includes the Global Livestock CRSP’s HIV Nutrition Project (HNP), “Increasing Animal Source Foods in Diets of HIV-infected Kenyan Women and Their Children,” which is a collaborative initiative between AMPATH and faculty from Moi University, Indiana University and the University of California, Los Angeles.This publication was made possible through support provided by the Office of Agriculture, Bureau of Economic Growth, Agriculture and Trade, under Grant No. PCE-G-00-98-00036-00 to University of California, Davis.

A qualitative assessment of barriers to antiretroviral therapy adherence among adolescents in western Kenya
Antiretroviral therapy (ART) requires nearly perfect adherence to be effective. This study aims to identify key factors identified by HIV-infected adolescents on ART as contributing to medication adherence in western Kenya. Using a qualitative study design, three adolescent focus groups discussions were conducted at an urban and rural clinic site in western Kenya. The study population included HIV-infected adolescents receiving ART through the USAID-AMPATH HIV care system. A trained facilitator conducted groups in Kiswahili using a semi-structured interview guide probing multiple aspects of experience of taking medicines. Transcribed focus group dialogues were analyzed using constant comparison, progressive coding, and triangulation. The adolescents described a context of negative societal beliefs about HIV, necessitating a lifestyle of secrecy and minimizing the information shared about HIV or ART. Assessing and addressing adolescents' fears and behaviors regarding medication secrecy and disclosure may enable more accurate monitoring of adherence and development of intervention strategies
Validation of a Short Adherence Questionnaire for Children Living with HIV on Antiretroviral Therapy in Kenya
Background:There are few validated tools to measure adherence for children living with HIV. We identified questionnaire items for caregivers of Kenyan children aged <15 years living with HIV.Methods:Caregiver?child dyads were followed for 6 months. At monthly visits, the child?s HIV provider administered a 10-item questionnaire to the caregiver. Children were given electronic dose monitors (Medication Event Monitoring Systems [MEMS]). Correlation between questionnaire items and dichotomized MEMS adherence (≥90% doses taken versus <90%) was investigated using logistic regression models.Results:In 95 caregiver?child dyads, mean age of children (40% female) was 8.3 years. Items associated with higher odds of MEMS adherence in multivariable analysis included the father giving the child medication, being enrolled in a nutrition program, and the caregiver reporting no difficulties giving the child medication.Conclusion:Providers typically ask about missed doses, but asking about caregiver responsibilities and difficulties in giving the child medication may better detect suboptimal adherence
Morbidity and nutrition status of rural drug-naïve Kenyan women living with HIV
This paper describes morbidity in a group of HIV-positive drug-naïve rural women in western Kenya. A total of 226 drug-naïve HIV-positive women were evaluated for baseline morbidity, immune function, and anthropometry before a food-based nutrition intervention. Kenyan nurses visited women in their homes and conducted semi-structured interviews regarding symptoms and physical signs experienced at the time of the visit and during the previous week and physical inspection. Blood and urine samples were examined for determination of immune function (CD4, CD8, and total lymphocyte counts), anaemia, malaria, and pregnancy status. Intradermal skin testing with tuberculin (PPD), candida, and tetanus toxoid antigens was also performed to evaluate cell-mediated immunity. Anthropometry was measured, and body mass index (BMI) was calculated. Seventy-six per cent of the women reported being sick on the day of the interview or within the previous week. Illnesses considered serious were reported by 13.7% of women. The most frequent morbidity episodes reported were upper respiratory tract infections (13.3%), suspected malaria (5.85%), skeletal pain (4.87%), and stomach pain (4.42%). The most common morbidity signs on physical inspection were respiratory symptoms, most commonly rhinorrhea and coughing. Confirmed malaria and severe diarrhea were significantly associated with a higher BMI
The Vulnerabilities of Orphaned Children Participating in Research: A Critical Review and Factors for Consideration for Participation in Biomedical and Behavioral Research
Orphans are a subpopulation with a unique set of additional vulnerabilities. Increasing focus on children’s rights, pediatric global health, and pediatric research makes it imperative to recognize and address unique vulnerabilities of orphaned children. This paper describes the unique vulnerabilities of the orphaned pediatric population and offers a structured set of factors that require consideration when including orphans in biomedical research. Pediatric orphans are particularly vulnerable due to decreased economic resources, psychosocial instability, increased risk of abuse, and delayed/decreased access to healthcare. These vulnerabilities are significant. By carefully considering each issue in a population in a culturally specific and study-specific manner, researchers can make valuable contributions to the overall health and well-being of this uniquely vulnerable population
