RESUMEN

Primary B-cell immunodeficiencies are risk factors for the generation of vaccine-derived polioviruses. We report immunodeficiency-associated vaccine-derived poliovirus serotype 3 in an 11-week-old boy with X-linked agammaglobulinemia. Unique characteristics of this case include early age of presentation, high viral evolutionary rate, and the child's perinatal exposure to human immunodeficiency virus.

RESUMEN

BACKGROUND: Isoniazid resistant tuberculosis is the most prevalent type of resistance in Swaziland and over two-thirds of the isoniazid resistant tuberculosis patients are tuberculosis and human immunodeficiency virus co-infected. The study aimed to determine risk factors associated with isoniazid resistant tuberculosis among human immunodeficiency virus positive patients in Swaziland. METHODS: This was a case-control study conducted in nine healthcare facilities across Swaziland. Cases were patients with isoniazid resistant tuberculosis (including 78 patients with isoniazid mono-resistant tuberculosis, 42 with polydrug-resistant tuberculosis, and 77 with multidrug-resistant tuberculosis). Controls were presumed drug-susceptible tuberculosis patients (n = 203). Multinomial logistic regression was used to determine related factors. RESULTS: The median time lag from diagnosis to tuberculosis treatment initiation was 50 days for isoniazid mono or poly drug-resistant tuberculosis, 17 days for multidrug-resistant tuberculosis compared to 1 day for drug-susceptible tuberculosis patients. History of previous tuberculosis treatment was positively associated with either isoniazid mono or poly drug-resistant tuberculosis (OR = 7.91, 95% CI: 4.14-15.11) and multidrug-resistant tuberculosis (OR = 12.20, 95% CI: 6.07-24.54). Isoniazid mono or poly resistant tuberculosis patients were more likely to be from rural areas (OR = 2.05, 95% CI: 1.23-3.32) and current heavy alcohol drinkers compared to the drug-susceptible tuberculosis group. Multi drug-resistant tuberculosis patients were more likely to be non-adherent to tuberculosis treatment compared to drug-susceptible tuberculosis group (OR = 3.01, 95% CI: 1.56-5.82). CONCLUSION: To prevent and control isoniazid resistant tuberculosis among HIV-positive patients in Swaziland, the tuberculosis program should strengthen the use of rapid diagnostic tests, detect resistance early, promptly initiate supervised tuberculosis treatment and decentralize quality tuberculosis services to the rural areas. Adherence to tuberculosis treatment should be improved.

RESUMEN

AIMS AND OBJECTIVES: This article reports on diet variability in the Dogon Country (Mali) through a bio-archeological study of pre-Dogon and early Dogon human remains (7th century to 19th century AD) from collective burial caves in the Bandiagara Escarpment. MATERIALS AND METHODS: Two hundred and twenty crania from collections curated in Leiden, Paris, and Bamako were studied for dental diseases. In a subset of teeth (n = 175), δ13 C and δ15 N were measured in bulk dentine samples. RESULTS: δ13 C and δ15 N values vary widely (-15.4 to -6.0‰ for δ13 C, 6.0-14.8‰ for δ15 N, n = 175), and indicate diets dominated by C4 -based foods with a focus on plants; animal products played a minor role. There are significant differences between the δ13 C values from older (pre-Dogon) and younger (Dogon) periods. Frequencies of caries, antemortem tooth loss, and abscesses increase significantly through time. Individuals from northern caves have more positive δ13 C and δ15 N values than southern ones. DISCUSSION AND CONCLUSIONS: The temporal shifts are probably due to progressive diversification of foods, consistent with archeological evidence showing the addition of rice and vegetables to pearl millet. The geographical disparity is explained by a combination of climatic, environmental, and cultural factors. Last, intersite differences imply that different communities (or subsections thereof) disposed of their dead in different caves. Based on a large sample extending over a wider area and longer time frame than previous work, our study shows that diets in the Dogon Country were neither uniform nor continuous through time, as previously proposed. Our results attest to a complex history of settlement and foodways.

RESUMEN

OBJECTIVE: To explore risk factors for sexual violence in childhood in a nationally representative sample of females aged 13 to 24 years in Swaziland. METHODS: During a household survey respondents were asked to report any experiences of sexual violence before the age of 18 years. The association between childhood sexual violence and several potential demographic and social risk factors was explored through bivariate and multivariate logistic regression. FINDINGS: Participants totalled 1244. Compared with respondents who had been close to their biological mothers as children, those who had not been close to her had higher odds of having experienced sexual violence (crude odds ratio, COR: 1.89; 95% CI: 1.14-3.14), as did those who had had no relationship with her at all (COR: 1.93; 95% CI: 1.34-2.80). In addition, greater odds of childhood sexual violence were noted among respondents who were not attending school at the time of the survey (COR: 2.26; 95% CI: 1.70-3.01); who were emotionally abused as children (COR: 2.04; 95% CI: 1.50-2.79); and who knew of another child who had been sexually assaulted (COR: 1.77; 95% CI: 1.31-2.40) or was having sex with a teacher (COR: 2.07; 95% CI: 1.59-2.69). Childhood sexual violence was positively associated with the number of people the respondent had lived with at any one time (COR: 1.03; 95% CI: 1.01-1.06). CONCLUSION: Inadequate supervision or guidance and an unstable environment put girls at risk of sexual violence. Greater educational opportunities and an improved mother-daughter relationship could help prevent it.

RESUMEN

BACKGROUND: In April 2014, a national school-based human papillomavirus (HPV) vaccination program was rolled out in South Africa, targeting Grade 4 girls aged ≥9 years. A bivalent HPV vaccine with a 2-dose (6 months apart) schedule was used. At the request of the National Department of Health (NDoH), we conducted an external assessment of the first-dose phase of the vaccination program to evaluate program coverage and vaccine safety and identify factors that influenced implementation. METHODS: We based our cross-sectional and mixed-methods approach on a process evaluation framework, which included a review of key planning and implementation documents and monitoring data; observation at vaccination sites; key informant interviews (N=34); and an assessment of media coverage and content related to the campaign.Findings: There was overall success in key measures of coverage and safety. Over 350,000 Grade 4 girls were vaccinated in more than 16,000 public schools across South Africa, which translated to 94.6% of schools reached and 86.6% of age-eligible learners vaccinated. No major adverse events following immunization were detected. We attributed the campaign's successes to careful planning and coordination and strong leadership from the NDoH. The primary challenges we identified were related to obtaining informed consent, vulnerabilities in cold chain capacity, and onsite management of minor adverse events. While campaign planners anticipated and prepared for some negative media coverage, they did not expect the use of social media for spreading misinformation about HPV vaccination. CONCLUSIONS: The first phase of the national school-based HPV vaccination campaign was successfully implemented at scale in this setting. Future implementation will require improvement in the storage and monitoring of vaccine doses, better communication of role expectations to all stakeholders, and streamlined consent processes to ensure program sustainability.

RESUMEN

During the past two decades, immunisation has saved millions of lives and prevented countless illnesses and disabilities in South Africa(SA). However, vaccine-preventable diseases are still a threat. A vaccine-preventable disease that might lead to a 1- or 2-week illness in anadult, could prove deadly for infants, children or elderly people. Vaccination protects oneself and one's family. For example, adults are themost common source of pertussis (whooping cough) infection in infants, which can be deadly for the latter. This article demonstrates thecommitment of the SA government to immunisation, highlights key milestones of the Expanded Programme on Immunisation (EPI) anddispels the myth that the EPI in SA is in shambles.
