Human papillomavirus vaccination acceptance and hesitancy in South Africa: Research and policy agenda

Cervical cancer is responsible for one-quarter of a million deaths per year worldwide. In South Africa (SA), cervical cancer is the leading cause of cancer deaths among women aged 15 - 44 years. Human papillomavirus (HPV) vaccines provide a safe and highly effective means to reduce the burden of cervical cancer. The World Health Organization initiated a plan for the elimination of cervical cancer; the programme’s success relies on the introduction and high uptake of HPV vaccines globally. SA introduced a school-based HPV vaccination programme in 2014, but uptake is not as high as expected. Suboptimal HPV vaccination coverage may result from various factors, including vaccine hesitancy. Vaccine-hesitant parents may delay or refuse HPV vaccination for their daughters. Tailored interventions are needed to address this. However, knowledge regarding vaccine hesitancy and policies to address this hesitancy in SA are currently limited. While SA has taken commendable steps in cervical cancer prevention by implementing and financing the HPV vaccination programme, it is imperative that there are clear policies in place to help strengthen the programme. These policies need to clarify areas of uncertainty that may lead to mistrust, and pre-empt factors that will cause hesitancy. Equally important is that local research should be conducted to better understand HPV vaccination hesitancy and other determinants of uptake to further inform and shape national policies

First candidates for γ vibrational bands built on the [505] 11/2− neutron orbital in odd-A Dy isotopes:

Rotational structures have been measured using the Jurogam II and GAMMASPHERE arrays at low spin following the 155Gd(α,2n)157Dy and 148Nd(12C,5n)155Dy reactions at 25 and 65 MeV, respectively. We report high-K bands, which are conjectured to be the first candidates of a Kπ=2+γ vibrational band, built on the [505]11/2− neutron orbital, in both odd-A155,157Dy isotopes. The coupling of the first excited K=0+ states or the so-called β vibrational bands at 661 and 676 keV in 154Dy and 156Dy to the [505]11/2− orbital, to produce a Kπ=11/2− band, was not observed in both 155Dy and 157Dy, respectively. The implication of these findings on the interpretation of the first excited 0+ states in the core nuclei 154Dy and 156Dy are also discussed

South African Paediatric Surgical Outcomes Study : a 14-day prospective, observational cohort study of paediatric surgical patients

BACKGROUND : Children comprise a large proportion of the population in sub-Saharan Africa. The burden of paediatric surgical disease exceeds available resources in Africa, potentially increasing morbidity and mortality. There are few prospective paediatric perioperative outcomes studies, especially in low- and middle-income countries (LMICs). METHODS : We conducted a 14-day multicentre, prospective, observational cohort study of paediatric patients (aged <16 yrs) undergoing surgery in 43 government-funded hospitals in South Africa. The primary outcome was the incidence of in-hospital postoperative complications. RESULTS : We recruited 2024 patients at 43 hospitals. The overall incidence of postoperative complications was 9.7% [95% confidence interval (CI): 8.4–11.0]. The most common postoperative complications were infective (7.3%; 95% CI: 6.2–8.4%). In-hospital mortality rate was 1.1% (95% CI: 0.6–1.5), of which nine of the deaths (41%) were in ASA physical status 1 and 2 patients. The preoperative risk factors independently associated with postoperative complications were ASA physcial status, urgency of surgery, severity of surgery, and an infective indication for surgery. CONCLUSIONS : The risk factors, frequency, and type of complications after paediatric surgery differ between LMICs and high-income countries. The in-hospital mortality is 10 times greater than in high-income countries. These findings should be used to develop strategies to improve paediatric surgical outcomes in LMICs, and support the need for larger prospective, observational paediatric surgical outcomes research in LMICs.

Work on Spoken (Multimodal) Language Corpora in South Africa

This paper describes past, ongoing and planned work on the collection and transcription of spoken language samples for all the South African official languages and as part of this the training of researchers in corpus linguistic research skills. More specifically the work has involved (and still involves) establishing an international corpus linguistic network linked to a network hub at a UNISA website and the development of research tools, a corpus research guide and workbook for multimodal communication and spoken language corpus research. As an example of the work we are doing and hope to do more of in the future, we present a small pilot study of the influence of English and Afrikaans on the 100 most frequent words in spoken Xhosa as this is evidenced in the corpus of spoken interaction we have gathered so far. Other planned work, besides work on spoken language phenomena, involves comparison of spoken and written language and work on communicative body movements (gestures) and their relation to speech
