Cervical Cancer (CC) is the number one cancer among women in sub-Saharan Africa. Although CC is preventable, most women in developing countries do not have access to screening. This cross-sectional study was conducted to determine the prevalence and risk factors for cervical lesions using visual inspection with acetic acid (VIA) among 112 HIV positive and 161 negative women aged 18–69 years. The presence of cervical lesions was greater among HIV positive (22.9%) than HIV negative women (5.7%; p < 0.0001). In logistic models, the risk of cervical lesions among HIV positive women was 5.24 times higher when adjusted by age (OR 5.24, CI 2.31–11.88), and 4.06 times higher in a full model (OR 4.06, CI 1.61–10.25), than among HIV negative women. In the age-adjusted model women who had ≥2 lifetime sexual partners were 3 times more likely (OR 3.00, CI 1.02–8.85) to have cervical lesions compared to women with one lifetime partner and the odds of cervical lesions among women with a history of STIs were 2.16 greater (OR 2.16, CI 1.04–4.50) than among women with no previous STI. In the fully adjusted model women who had a previous cervical exam were 2.5 times more likely (OR 2.53, CI 1.06–6.05) to have cervical lesions than women who had not. The high prevalence of HIV infection and the strong association between HIV and cervical lesions highlight the need for substantial scale-up of cervical screening to decrease the rate of CC in Swaziland.

Background: In addition to governmental regulation and scientific advancements, the World Health Organization requires extensive review of local opinions before initiating clinical trials of xenotransplantation (XTx). The purpose of this study was to assess the attitudes of health care providers and patients regarding XTx.Methods: An anonymous Likert-scale survey regarding attitudes toward XTx was distributed to pre- and post-kidney transplant patients, nephrologists, transplant surgeons, and nurses (“providers”). Patient and provider responses were described and compared. Regression analysis using patients’ responses was performed to identify factors associated with XTx acceptance.Results: Eighty percent (32/40) of providers and 69% (113/163) of patients were agreeable to clinical XTx if the risks and results were likely to be similar to kidney allotransplantation (P<0.05). Kidney providers rated the influence of religious beliefs in medical decisions (45% versus 15%) and genetic engineering (43% versus 25%) as being more important than did patients (P<0.05). A small proportion in both groups (<15%) reported concerns about (1) potential personality changes, (2) how others would interact, (3) a perception of being “less human,” or (4) morals or ethics. Logistic regression found that the odds of patients accepting XTx were greater if they had no religious concerns (OR, 25.10; 95% CI, 2.59 to 243.00), but acceptance was less likely if they were not willing to use XTx as a bridge to allotransplantation (OR, 0.18; 95% CI, 0.51 to 0.70).Conclusions: (1) If outcomes were similar to allotransplantation, XTx support was strong among both providers and patients; (2) providers overestimated the influence of religious beliefs and genetic engineering on patient medical decisions, although religious beliefs are associated with XTx acceptance; (3) XTx use as a bridge to allotransplant was associated with XTx acceptance; and (4) psychosocial concerns were low for either group. Future studies among other communities are warranted to assess if similar attitudes exist.

Aflatoxins are produced by the fungi Aspergillus flavus and Aspergillus parasiticus and are common food contaminants in tropical developing countries. Extensive aflatoxin consumption has been shown to be highly associated with liver disease. A case-control study was conducted to determine the association between aflatoxin and liver disease in Kumasi, Ghana. A questionnaire was administered to examine socio-demographic characteristics and food storage and consumption practices, and urine samples were collected to measure levels of the aflatoxin metabolite (AFM₁). Two hundred and seventy-six people participated in the study; 38 had liver disease (cases), 136 had neither hepatitis B/C nor liver disease (negative controls), and 102 were hepatitis B/C positive without liver cancer (positive controls). A much higher percent of participants in each group was male (76% of cases, 88% of negative controls and 65% of positive controls). Multivariate analysis showed that age was a significant predictor for being a case when cases were compared to negative controls. The odds of being a case was 70% less for participants aged 25–34 years (odds ratios (OR) 0.30; 95% confidence interval (CI) 0.10–0.88) compared to those ≥45 years. For cases; Akans were seven times more likely to have AFM₁ levels below the median when compared to other ethnic groups (OR 7; CI 1.41–34.68). When cases were compared to positive controls, they were 2.29 times more likely to report awareness of aflatoxin contamination of groundnuts (95% CI 1.06–4.91). Cases were also two times more likely to report awareness of aflatoxin contamination of maize than all controls combined (95% CI 1.02–4.11). However, most cases reported that aflatoxin contamination does not cause sickness in humans. This shows that there is awareness of aflatoxin contamination without proper understanding of the serious potential adverse health impacts among these study participants. These findings indicate that educational interventions that stress the harmful health effects of aflatoxin in food, with an emphasis on the higher risk for males, are urgently needed. The reasons for lower aflatoxin levels among Akans need to be determined, and the findings used to design interventions that benefit other ethnic groups in the society.
