Risk factors for tuberculosis smear non-conversion in Eden district, Western Cape, South Africa, 2007-2013 : a retrospective cohort study

BACKGROUND : Tuberculosis (TB) continues to be a major global health problem. While progress has been made to improve TB cure rates, South Africa’s 76 % smear-positive pulmonary TB (PTB) case cure rate remains below the WHO target of 85 %. We report on the trends of TB smear non-conversion and their predictors at the end of an intensive phase of treatment, and how this impacted on treatment outcomes of smear-positive PTB cases in Eden District, Western Cape Province, South Africa. METHODS : Routinely collected, retrospective data of smear-positive PTB cases from the electronic TB register in Eden District between 2007 and 2013 was extracted. Non-conversion was defined as persistent sputum smear-positive PTB cases at the end of the two or three month intensive phase of treatment. Chi-square test for linear trend and simple linear regression analysis were used to analyse the change in percentages and slope of TB smear non-conversion rates over time. Risk factors for TB non-conversion, and their impact on treatment outcomes, were evaluated using logistic regression models. RESULTS : Of 12,742 total smear-positive PTB cases included in our study, 12.8 % (n = 1627) did not sputum smear convert; 13.3 % (1411 of 10,574) of new cases and 9.9 % (216 of 2168) of re-treatment cases. Although not statistically significant in either new or re-treatment cases, between 2007 and 2013, smear non-conversion decreased from 16.4 to 12.7 % (slope = −0.60; 95 % CI: −1.49 to 0.29; p = 0.142) in new cases, and from 11.3 to 10.8 % in re-treatment cases (slope = −0.29; 95 % CI: −1.06 to 0.48; p = 0.376). Male gender, HIV co-infection and a >2+ acid fast bacilli (AFB) smear grading at the start of TB treatment were independent risk factors for non-conversion (p < 0.001). Age was a risk factor for non-conversion in new cases, but not for re-treatment cases. Non-conversion was also associated with unsuccessful treatment outcomes (p < 0.01), including treatment default and treatment failure. CONCLUSIONS : Smear-positive PTB cases, especially men and those with identified risk factors for non-conversion, should be closely monitored throughout their treatment period. The South African TB control program should invest in patient adherence counselling and education to mitigate TB non-conversion risk factors, and to improve conversion and TB cure rates.This study was supported by PEPFAR funding through CDC South Africa and Foundation for Professional Development.http://www.biomedcentral.com/bmcinfectdis/hb2016School of Health Systems and Public Health (SHSPH

Establishment of a cancer surveillance programme : the South African experience

Cancer is projected to become a leading cause of morbidity and mortality in low-income and middle-income countries in the future. However, cancer incidence in South Africa is largely under-reported because of a lack of nationwide cancer surveillance networks. We describe present cancer surveillance activities in South Africa, and use the International Agency for Research on Cancer framework to propose the development of four population-based cancer registries in South Africa. These registries will represent the ethnic and geographical diversity of the country. We also provide an update on a cancer surveillance pilot programme in the Ekurhuleni Metropolitan District, and the successes and challenges in the implementation of the IARC framework in a local context. We examine the development of a comprehensive cancer surveillance system in a middle-income country, which might serve to assist other countries in establishing population-based cancer registries in a resource-constrained environment.http://www.journals.elsevier.com/the-lancet-oncology2016-08-31hb2016School of Health Systems and Public Health (SHSPH

A pilot study assessing the impact of a fortified supplementary food on the health and well-being of crèche children and adult TB patients in South Africa.

The South African population faces many of the global concerns relating to micronutrient deficiency and the impact this has on health and well-being. Moreover, there is a high prevalence of HIV infection, compounded by a high level of co-infection with TB.This pilot study evaluates the impact of a fortified supplementary food on the health and well-being of a cohort of crèche children, aged 3 to 6, and adult TB patients drawn from the Presidential Node of Alexandra, Johannesburg, South Africa. A further aim of this study was to evaluate the sensitivity and validity of non-invasive indicators of nutritional status in a field-based population sample.The investigational product, e'Pap, is supported by extensive anecdotal evidence that whole grain cereals with food-style nutrients constitute an effective supplementary food for those suffering from the effects of food insecurity, poor health and well-being, and coping with TB and HIV infection.The results indicate a beneficial effect of e'Pap for both study populations, and particularly for adult TB patients, whose baseline data reflected severe food insecurity and malnutrition in the majority of cases. There is evidence to suggest statistically significant improvements in key micronutrient levels, well-being and energy, hand-grip strength, the Bioelectrical Impedance Analysis (BIA) Illness Marker, and certain clinical indicators. Although Body Mass Index (BMI) and Mid Upper Arm Circumference (MUAC) are frequently used as standard measures to evaluate the efficacy of nutritional interventions, these indicators were not sufficiently sensitive in this study. Nor does weight gain necessarily indicate improved nutritional status. Hand-grip strength, lean body mass, and the BIA Illness Marker seem to be more useful indicators of change in nutritional status

Assessment of adolescent and youth friendly services in primary healthcare facilities in two provinces in South Africa

Abstract Background Health services for adolescents are increasingly recognised as a priority in low- and middle-income countries (LMICs). The Adolescent and Youth Friendly Service (AYFS) approach has been promoted in South Africa by the National Department of Health and partners, as a means of standardising the quality of adolescent health services in the country. The objective of this paper is to detail the evaluation of AYFS against defined standards to inform initiatives for strengthening these services. Methods A cross-sectional assessment of AYFS was carried out in 14 healthcare facilities in a sub-district of Gauteng Province and 16 in a sub-district in North West Province, South Africa. Data on adolescent care and service management systems were collected through interviews with healthcare providers, non-clinical staff and document review. Responses were scored using a tool based on national and World Health Organisation criteria for ten AYFS standards. Results Mean scores for the ten standards showed substantial variation across facilities in the two sub-Districts, with Gauteng Province scoring lower than the North West for 9 standards. The sub-district median for Gauteng was 38% and the North West 48%. In both provinces standards related to the general service delivery, such as Standards 4 and 5, scored above 75%. Assessment of services specifically addressing sexual, reproductive and mental health (Standard 3) showed that almost all these services were scored above 50%. Exploration of services related to psycho-social and physical assessments (Standard 8) demonstrated differences in the healthcare facilities’ management of adolescents’ presenting complaints and their comprehensive management including psycho-social status and risk profile. Additionally, none of the facilities in either sub-district was able to meet the minimum criteria for the five standards required for AYFS recognition. Conclusion Facilities had the essential components for general service delivery in place, but adolescent-specific service provision was lacking. AYFS is a government priority, but additional support for facilities is needed to achieve the agreed standards. Meeting these standards could make a major contribution to securing adolescents’ health, especially in preventing unintended pregnancies and HIV as well as improving psycho-social management
