Successful paediatric HIV treatment in rural primary care in Africa

<p>Objective: Clinical outcomes of HIV-infected children on antiretroviral treatment (ART) in a decentralised, nurse/counsellor-led programme.</p> <p>Design: Clinical cohort.</p> <p>Setting: KwaZulu-Natal, South Africa.</p> <p>Patients: HIV-infected children aged <= 15 years on ART, June 2004-2008.</p> <p>Main outcome measures: Survival according to baseline characteristics including age, WHO clinical stage, haemoglobin and CD4%, was assessed in Kaplan-Meier analyses. Hazard ratios for mortality were estimated using Cox proportional hazards regression and changes in laboratory parameters and weight-for-age z scores after 6-12 months' treatment were calculated.</p> <p>Results: 477 HIV-infected children began ART at a median age of 74 months (range 4-180), median CD4 count (CD4%) of 433 cells/mm(3) (17%) and median HIV viral load of log 4.2 copies/ml; 105 (22%) were on treatment for tuberculosis and 317 (76.6%) were WHO stage 3/4. There were significant increases after ART initiation in CD4% (17% vs 22%; p<0.001), haemoglobin (9.9 vs 11.7 g/l; p <= 0.001) and albumin (30 vs 36 g/l; p <= 0.001). 32 (6.7%) children died over 732 child-years of follow-up (43.7 deaths/1000 child-years; 95% CI 32.7 to 58.2), 17 (53.1%) within 90 days of treatment initiation; median age of death was 84 (IQR 10-181) months. Children with baseline haemoglobin <= 8 g/l were more likely to die (adjusted HR 4.5; 95% CI 1.6 to 12.3), as were those aged <18 months compared with >60 months (adjusted HR 3.2; 95% CI 1.2 to 9.1).</p> <p>Conclusions Good clinical outcomes in HIV-infected children on ART are possible in a rural, decentralised service. Few young children are on ART, highlighting the urgent need to identify HIV-exposed infants.</p&gt

Perception of University Managers on the Influence of Organizational Structure on Quality of Management in Public and Private Universities in Kenya

Quality of institutional management is arguably a major determinant of organizational performance.  The role of managers and the activities and tasks they perform as aided by the organizational structure could lead to the effective and efficient implementation of organizational objectives and goals.  This study was undertaken to establish the perception of university managers on the influence of organizational structure on the quality of institutional management of universities in Kenya.  The study design was descriptive research. Purposive sampling procedure was used in selecting the universities.  Random stratification sampling was used to administer the questionnaire to the managers in the universities.  Positive responses were received from 137 managers from a target of 263 giving a 62.6%  response rate.  The response from university managers showed an average positive response rate at 60%.  There was a statistically significant difference at (p<0.05) on the perception of managers in the public and private universities on the influence of organizational structure on the dimension of customer satisfaction. The organizational structures in the private universities were found to be more customer centric than those of public universities. Private universities management practices emphasized concern for customer needs.  This translated into provision of quality services and products in order to meet customers’ expectations for their satisfaction and retention.  .

Knowledge, attitudes and practices of infertile couples on male participation in infertility management at the Kenyatta National Hospital

Objective: To determine knowledge, attitudes and practices of infertile couples on male involvement in the management of infertility.Design: Hospital based cross-sectional study.Setting: Kenyatta National Hospital, Nairobi, Kenya.Subjects: One hundred sixty three infertile couples attending the gynaecological and infertility clinics at the Kenyatta National Hospital.Main outcome measures: Knowledge, attitudes and practices of infertile couples on male participation in infertility management.Results: A total of 163 infertile couples(with only 34 men accompanying their wives in this study period) were recruited into the study. Sixty nine point nine percent(114) of the women who participated in this study were ever accompanied to the clinic by their spouses, but only 20.9%(34) were accompanied during the study period. Couple awareness on male participation in infertility was 61.8% by the men and 67.5% by the women but they all agreed that it would improve the care given. The male partners who came to the clinic were more involved in the care of their partners, in terms of paying hospital bills, having investigations performed on them, participating in the decision making process and accepting treatment (p<0.05). On multiple logistic regression, it was found that male partners of accompanied women were paying the medical bills (p value = 0.017, OR=3.0[1.2-7.4]), being investigated (p-value=0.011, OR=3.1[1.3-7.5]), helping decide the treatment the partner receives (p-value = 0.04, OR=2.5[1.0-5.9]) and accepting treatment if found to have a problem (p-value=0.005, OR=4.0[1.5-10.5]).Conclusion: Male participation in infertility management was low 34(20.9%) and structures need to be put in place to improve male partner participation in infertility management

Mandrax use, sexual risk, and opportunities for pre-exposure prophylaxis among out-of-school adolescent girls and young women in Cape Town, South Africa

Background. In South Africa (SA), adolescent girls and young women (AGYW) aged 15 - 24 years account for nearly 25% of all new HIV infections in the country. The intersection of substance use and sexual risk continues to drive the HIV epidemic among AGYW. For example, methaqualone, also known as Mandrax, has sedative effects that may affect women’s ability to negotiate condom use during sex, refuse sex without a condom, or consent to sex, thereby increasing their risk for HIV. Consequently, it is critical to understand how Mandrax use affects HIV risk among AGYW and to assess awareness of and willingness to use biomedical HIV prevention methods, such as pre-exposure prophylaxis (PrEP), among AGYW who use Mandrax.Objectives. To examine the role of Mandrax use in sexual behaviours and investigate the extent to which AGYW who use Mandrax are aware of and willing to initiate PrEP.Methods. Data for this report were derived from baseline and 6-month follow-up data provided by 500 AGYW participating in a cluster-randomised trial assessing the efficacy of a young woman-focused intervention to reduce substance use and HIV risk. AGYW who self-identified as black African or coloured, reported using substances, reported condomless sex in the past 3 months, and had discontinued school early were recruited from 24 community clusters across Cape Town, SA. Following consent/assent, participants provided biological specimens to test for recent drug use (including Mandrax) and completed the self-report questionnaire.Results. Logistic regression analysis revealed that the AGYW who had a positive test result for Mandrax use were less likely to use a condom with their main partner (p=0.01), and almost three times more likely to use alcohol and/or other drugs before or during their last act of sexual intercourse (p<0.001), compared with the AGYW who had a negative Mandrax test result. Mandrax use was not significantly related to PrEP awareness (p>0.10) or willingness to use PrEP (p>0.10), but 70% of AGYW who used Mandrax were willing to initiate PrEP.Conclusion. The study findings highlight how Mandrax use may contribute to HIV risk among SA AGYW. Key decision-makers should consider incorporating substance use prevention efforts into existing HIV reduction programmes and equip youth-friendly clinics with the resources to identify AGYW who use Mandrax and offer them PrEP

Substance use and depressive and anxiety symptoms among out-of-school adolescent girls and young women in Cape Town, South Africa

Background. There is a high prevalence of substance use among youth in South Africa (SA), and adolescent girls and young women (AGYW) experience high rates of depression and anxiety. Substance use behaviours and mental health are associated with other public health problems among AGYW such as HIV and unintended pregnancy. Therefore, understanding the relationship between substance use and mental health is imperative to improve AGYW’s health.Objectives. To examine the association between heavy drinking, marijuana, methamphetamine and methaqualone (Mandrax) use and depressive and anxiety symptoms among AGYW aged 16 - 19 years who have dropped out of school in Cape Town, SA.Methods. Data for this report come from the baseline data of 500 participants of an ongoing cluster-randomised trial assessing the efficacy of a young woman-focused intervention to reduce substance use and HIV risk. After AGYW consented/assented to participate, they completed a urine drug screen and a baseline questionnaire.Results. Logistic and negative binomial regressions, controlling for clustering at the neighbourhood level, revealed that frequency of depressive symptoms was significantly and positively related to a positive drug screen for Mandrax (β=0.07; p=0.03). All other associations between the frequency of depressive symptoms and substance use were not statistically significant (ps>0.05). The associations between frequency of anxiety symptoms and substance use were not statistically significant (ps>0.05).Conclusions. Our findings highlight the need to address substance use, especially Mandrax use and its associated risk, and depression in an integrated, youth-friendly setting

Validating child vaccination status in a demographic surveillance system using data from a clinical cohort study: evidence from rural South Africa

<p><b>Background:</b> Childhood vaccination coverage can be estimated from a range of sources. This study aims to validate vaccination data from a longitudinal population-based demographic surveillance system (DSS) against data from a clinical cohort study.</p> <p><b>Methods:</b> The sample includes 821 children in the Vertical Transmission cohort Study (VTS), who were born between December 2001 and April 2005, and were matched to the Africa Centre DSS, in northern KwaZulu-Natal. Vaccination information in the surveillance was collected retrospectively, using standardized questionnaires during bi-annual household visits, when the child was 12 to 23 months of age. DSS vaccination information was based on extraction from a vaccination card or, if the card was not available, on maternal recall. In the VTS, vaccination data was collected at scheduled maternal and child clinic visits when a study nurse administered child vaccinations. We estimated the sensitivity of the surveillance in detecting vaccinations conducted as part of the VTS during these clinic visits.</p> <p><b>Results:</b> Vaccination data in matched children in the DSS was based on the vaccination card in about two-thirds of the cases and on maternal recall in about one-third. The sensitivity of the vaccination variables in the surveillance was high for all vaccines based on either information from a South African Road-to-Health (RTH) card (0.94-0.97) or maternal recall (0.94-0.98). Addition of maternal recall to the RTH card information had little effect on the sensitivity of the surveillance variable (0.95-0.97). The estimates of sensitivity did not vary significantly, when we stratified the analyses by maternal antenatal HIV status. Addition of maternal recall of vaccination status of the child to the RTH card information significantly increased the proportion of children known to be vaccinated across all vaccines in the DSS.</p> <p><b>Conclusion:</b> Maternal recall performs well in identifying vaccinated children aged 12-23 months (both in HIV-infected and HIV-uninfected mothers), with sensitivity similar to information extracted from vaccination cards. Information based on both maternal recall and vaccination cards should be used if the aim is to use surveillance data to identify children who received a vaccination.</p&gt

Efficacy of combination therapy using extracts of Aloe secundiflora Eng L and Callistemon citrinus William C. in Leishmania major infected BALB/c mice

Background: Leishmania major causes cutaneous leishmaniasis which leads to painful skin sores in humans. In the current study, efficacy of combination therapy of A. secundiflora and C. citrinus against L. major infected mice treated intra-peritoneally and orally was studied. Pentostam administered intra-peritoneally and phosphate buffered saline intra-peritoneally and orally were used as a controls.Objective: To determine the efficacy of combined therapy of C. citrinus and A. secundiflora extracts in Leishmania major infected BALB/c mice.Design: Experimental-Laboratory based studySetting: Kenya Medical Research Institute (Leishmania Department)Subjects: Eight weeks Male BALB/c MiceResults: The minimum inhibitory concentration (MICs) of aqueous extracts of A. secundiflora (A), and C. citrinus (B) were 2 mg/ml and 5 mg/ml respectively while the IC50 for the same extracts were 467.09μg/ml and 457.88μg/ml respectively. The combination of these extracts at ratio (1:1) supported minimal growth of L. major promastigotes and had IC50 of 58.45μg/ml as compared to MICs of 12.50μg/ml for Pentostam. The combination therapy had Infection rate (IR) of 19% and MI of 52.81% compared to Pentostam (IR=21% and MI=11.64%). The combination therapy reduced the footpad lesion size significantly (P < 0.05) just like the Pentostam control drug and no significant nitric oxide was stimulated. The oral and intra-peritoneal combination treatment reduced spleen amastigotes in mice by 73.46% and 78.12% corresponding to total LDUs of 10.87±0.64 and 8.96±0.82 respectively compared to Pentostam at 94.58% and LDU of 2.22±0.13. The difference between efficacy of Pentostam and that of combined extracts was almost significant (t= 2.653, P= 0.057).Conclusion: The combination therapy was active against L. major parasite, reduced lesion size significantly and did not prevent visceralisation but reduced spleen parasite load significantly
