Malariometric indices from Iganga, Uganda: baseline characterization in preparation of GMZ2 vaccine trial

Background: Malaria still remains the leading cause of childhood morbidity and mortality in Uganda. Interventions like malaria vaccines which reduce the malaria burden are needed in malaria endemic communities. There is need to establish baseline characteristics in vaccine trial study sites. This study determined the following baseline malariometric indices: spleen rates, bed net use, malaria parasitaemia and malaria episodes in an inception cohort of children aged 12 – 60 months in Iganga district, Uganda. Methods: In a longitudinal cohort study, 748 children were enrolled with 397 in an active follow up arm and 351 in a passive arm. The children in the two arms were followed for 6 months to determine the incidence of malaria episodes. Results: The overall baseline spleen rate was 8.2% (61/748) among the study participants. Of the households surveyed, about 36% reported using bed nets and almost 30% of the users had insecticide-treated nets. 274 (36.6%) of the study participants had a history of fever in the past 24 hrs at the time of the baseline survey. All participants had a peripheral blood smear for malaria parasites done at enrollment with 76.8% having the asexual form of malaria parasites. The malaria episodes per child per year were 1.5 and 0.79 in the active and passive follow up arms respectively. Conclusions: There is a high prevalence of malaria asexual parasitaemia in children below five years. The bed net usage still remains low among this population. These baseline malariometric indices have important implication for malaria control interventions

Population level usage of health services, and HIV testing and care, prior to decentralization of antiretroviral therapy in Agago District in rural Northern Uganda: Additional Files

A study protocol developed to investigate health service usage, particularly HIV testing and care, in 2/6 parishes of the Lapono sub-county of northern Uganda, prior to introduction of AntiRetroviral Therapy (ART) services in Lira Kato Health Centre (a local lower-level health centre III). The protocol consists of household and individual questionnaires which were administered to members of each household. These captured individual demographic and health-related information on adults (aged 15–59 years) and socioeconomic data on children living in each household. The protocol was approved by the Joint Clinical Research Centre/Research Ethical Committee (JCRC/REC), Uganda National Council for Science and Technology (UNCST) and Office of the President of the Republic of Uganda

Prevalence and types of cognitive impairment among patients with stroke attending a referral hospital in Uganda

Background Cognitive impairment is associated with short and long term adverse outcomes in stroke patients that may impair functional recovery during their rehabilitative process.Aims This study determined the prevalence, grades and demographic factors associated with cognitive impairment among patients with stroke attending Mulago National Referral Hospital in Uganda, a teaching hospital for Makerere University College of Health Sciences.Methods This was a cross-sectional descriptive study conducted from Mulago National Referral Hospital between June 2006 and March 2007. Eighty five patients with stroke confirmed by brain computed tomography scan, consenting either by themselves or by their guardians, were consecutively recruited from the Medical wards, Neurology clinic and the Physiotherapy department. A standardized questionnaire was interviewer administered, to obtain demographic and clinical data, and the Mini-Mental State Examination instrument was used to screen and grade cognitive impairment.Results Of the 85 patients evaluated, 70 (82.4%) had infarct and 15 (17.6%) hemorrhagic stroke. Fifty-four (63%, 95% confidence interval (CI): 53 - 73) had cognitive impairment; of which 23 (27%) and 14 (16%) had mild and moderate cognitive impairment respectively accounting for 43% of the cognitively impaired but with no dementia, and 17 (20%) had severe cognitive impairment (dementia). The only socio-demographic factor associated with cognitive impairment was age . 40 years (odds ratio (OR) 4, 95% CI 1.2 - 13.4, P = 0.024). Conclusions The prevalence of cognitive impairment among patients with stroke is high. Increasing age is significantly associated with cognitive impairment. There is need for neurocognitive assessment programs among stroke patients and the introduction of rehabilitation services should target to maximize their functional recovery

Next generation catalogues: an analysis of user search strategies and behavior

The movement from online catalogues to search and discovery systems has not addressed the goals of true resource discoverability. While catalogue user studies have focused on user search and discovery processes and experiences, and construction and manipulation of search queries, little insight is given to how searchers interact with search features of next generation catalogues. Better understanding of user experiences can help guide informed decisions when selecting and implementing new systems. In this study, fourteen graduate students completed a set of information seeking tasks using UIUC's VuFind installation. Observations of these interactions elicited insight into both search feature use and user understanding of the function of features. Participants used the basic search option for most searches. This is because users understand that basic search draws from a deep index that always gives results regardless of search terms; and because it is convenient, appearing at every level of the search, thus reducing effort and shortening search time. Participants rarely used advanced search but selected it as a secondary alternative, especially when searching for local library or print collections. Participants understand an online catalogue as a list of library holdings that provides access to local print collections; and offers options for refining voluminous result sets. Participants frequently used author, title, subject, keywords; and citation, search within, print, save, e-mailing, fulltext download that offered clear alternatives to searching and search reformulation respectively. Such features are familiar to users from past search experiences and puts them in control of the system. Participants understand the function of VuFind features based on their perception and preference that: VuFind will give relevant and current information because of the large collection size at UIUC; because of their prior experiences with quick, minimal effort search reformulation strategies; and VuFind‘s large result sets, presented in systematic and logical order. The evidence confirms that information tasks guide and shape the way searchers select and use system features. Participant search processes change during and after using a specific system. Alternatives to improve the design of more robust search features are proposed

Health service delay among pulmonary tuberculosis patients presenting to a National Referral Hospital, Kampala, Uganda: a cross sectional study

Introduction: Delay in the diagnosis of pulmonary tuberculosis (PTB) is common in many countries in Sub-Saharan Africa. Timely diagnosis of active tuberculosis is crucial in minimizing morbidity and mortality in the community as well as nosocomial transmission in health care facilities. This study aimed at determining factors associated with health service delay in the diagnosis and initiation of treatment among new PTB patients presenting to the National Referral Hospital-Mulago.Methods: This was a cross-sectional study among eligible new PTB patients presenting at the National referral TB treatment center Mulago hospital, between March to May 2009. The patients were consecutively recruited and interviewed using a semi-structured questionnaire to assess socio- demographic and health service factors. Multivariate logistic regression using odds ratios and 95% confidence intervals was done.Results: Two hundred and sixty six newly diagnosed PTB patients were enrolled, of which 65.4% experienced health systems delay. The median health service delay was 9days (IQR=8-19). Factors associated with health service delay were: 1n-patient (OR= 4.68, 95% CI: 1.91-11.45), secondary as highest level of education attained (OR= 3.56, 95% CI: 1.18-10.74), primary as highest level of education attained (OR= 6.70, 95% CI: 2.13-21.02), presence of fever (OR= 3.28, 95% CI: 1.05-10.79), and patient delay at health facility (OR= 5.01, 95% CI: 1.33-18.9). Conclusion: The study found a significant proportion of Health service delay among pulmonary tuberculosis patients presenting at the referral hospital. Being an in-patient and having fever as a symptom of tuberculosis needs further attention in order to have timely diagnosis. There is need for awareness on TB especially that most of the TB symptoms present like other febrile illnesses such as malaria and needs consideration when patients present to a health facility.Key words: Tuberculosis, health service delay, treatment delay, diagnostic delay, pulmonary tuberculosi

E Nakimuli-Mpungu1,2,3, B Mutamba2,3, S Nshemerirwe2,3, MS Kiwuwa4, S Musisi21Mental Health Department, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, USA; 2Department of Psychiatry, Makerere College of Health Sciences, School of Medicine, Kampala; 3Butabika National Referral Mental Hospital, Ministry of Health, Kampala; 4Clinical Epidemiology Unit, Makerere College of Health Sciences, School of Medicine, Kampala, UgandaIntroduction: Understanding factors affecting the time to recovery from acute mania is critical in the management of manic syndromes. The aim of this study was to determine the effect of HIV infection on time to recovery from acute mania.Methods: We performed a retrospective study in which medical charts of individuals who were treated for acute mania were reviewed. Survival analysis with Cox regression models were used to compare time to recovery from an acute manic episode between human immunodeficiency virus (HIV)-positive individuals and HIV-negative individuals.Results: Median survival time was one week for HIV-positive individuals and more than four weeks for HIV-negative individuals (Χ2 = 18.4, P value = 0.000). HIV infection was the only marginally significant independent predictor of survival probability on the acute admission ward (hazards ratio 2.87, P = 0.06).Conclusion: Acute mania in HIV-infected persons responds faster to psychotropic drugs compared with that in HIV-negative persons.Keywords: HIV-related mania, bipolar disorder, HIV infection, Uganda, immunodeficiency viru

Prevalence of suicidal ideation and attempt: associations with psychiatric disorders and HIV/AIDS in post-conflict Northern Uganda.

BACKGROUND: Research on the prevalence of suicidal ideation, attempt, and cormorbid psychiatric disorders in post-conflict areas is still limited. AIM: We explored the prevalence of suicidal ideation, attempt, associated psychiatric disorders and HIV/AIDS in post-conflict Northern Uganda, an area that experienced civil strife for over two decades. METHODS: A total of 2400 respondents (aged 18 and above) and randomly selected in three districts (Gulu, Amuru and Nwoya), were interviewed. Multivariable logistic regression was used to assess for associations between suicidality (suicidal ideation and attempt) and psychiatric cormorbidities. RESULTS: The prevalence of suicidal ideation and attempt were 12.1 % and 6.2 % respectively. Suicidality was significantly (P<0.001) higher among respondents with major depressive disorder (adjusted Odds Ratio (OR) = 9.5; 95%CI= 7.4, 12.1) and post-traumatic stress disorder (adjusted OR =2.4; 95%CI= 1.6, 3.6). Men had lower odds of ideating or attempting suicide compared to women (adjusted OR = 0.55; 95%CI: 0.38, 0.82). CONCLUSION: The prevalence rate of suicide ideation and attempt indicate a major public health problem in post-conflict Northern Uganda. Effective public mental health programs that that target both suicidality and psychiatric co-morbodities will be vital. Special attention should be given to women in post conflict Northern Uganda
