TL;DR: Giving continuous oral propranolol treatment is effective in preventing recurrent upper gastrointestinal bleeding in patients with non-cirrhotic portal fibrosis.
Abstract: Fifty patients with non-cirrhotic portal fibrosis who were admitted to hospital because of upper gastrointestinal bleeding were randomly assigned to treatment with either oral propranolol given in doses that reduced the resting pulse rate by 25% (25 patients) or with a placebo (25 patients). One year after the start of the study 20 patients in the propranolol group and five patients in the placebo group were free from recurrent gastrointestinal bleeding (p less than 0.0001). Giving continuous oral propranolol treatment is therefore effective in preventing recurrent upper gastrointestinal bleeding in patients with non-cirrhotic portal fibrosis.

TL;DR: It was concluded that long-term addition of sewage sludge/effluent to soil at Pension farm had increased the concentration of Zn and Cu in top soil to levels that pose environmental concern and the consumption of leafy vegetables produced on these soils pose a health risk to poor communities that reside around the study site, especially children, through possible Zn toxicity.
Abstract: The use of sewage sludge and effluent as a source of nutrients and water for crop production is increasing worldwide. A study was conducted in 2001 at Pension farm (near Harare) to determine the effect of long term (>30 yrs) application of sewage sludge and effluent on Zn and Cu accumulation in top soil, uptake of these metals by lettuce (Lactuca sativa L.) and mustard rape (Brassica juncea L.), and dry matter yield. Application of sewage sludge/effluent significantly (p < 0.001) increased total Zn (13.7–1563.9 mg kg−1) and Cu (2.5–133.3 mg kg−1) in the top soil (0–20 cm depth) compared to the control. Sewage sludge/effluent addition significantly (p < 0.001) increased Zn uptake by both test crops, while Cu uptake was significant in the first crop of lettuce and the second crop of mustard rape. Based on the dietary patterns of poor urban households in Zimbabwe, the maximum possible intake of Cu will only constitute 40% the Maximum Daily Intake (MDI). The toxicological implications for Zn will how...

TL;DR: The significant association between abortion history and seropositivity observed in this study illustrates the potential economic significance of Brucella in cattle in this area and further epidemiological studies of the disease in wildlife, livestock, and humans in the study area are of great importance.
Abstract: A cross-sectional study was conducted to determine the seroprevalence of bovine brucellosis in communal cattle and wildlife at a wildlife–livestock interface in the southeast lowveld of Zimbabwe, part of the Great Limpopo Transfrontier Conservation Area. RBT and c-Elisa were used in serial for detection of antibodies against Brucella spp. Between July 2007 and October 2009, a total of 1,158 cattle were tested and the overall seroprevalence of brucellosis was 9.9%. A total of 97 wild animals (African buffaloes (n = 47), impala (n = 33), kudu (n = 16), and giraffe (n = 1)) were tested and only one animal (giraffe) was seropositive for brucellosis (1.03%). Brucella seroprevalence showed an increasing trend with age, with adult cattle (>6 years) recording the highest seroprevalence (11.1%), but the differences were not statistically significant. Similarly, female cattle recorded a relatively higher seroprevalence (10.8%) compared to males (7.9%), but the difference was not significant. However, a significant (P < 0.001) association between Brucella seropositivity and abortion history was recorded in female cattle. Similarly, Brucella seropositivity was significantly (P < 0.01) associated with a history of grazing in the park for female cattle. Overall, from the interface area, cattle with a history of grazing in the park recorded a significantly (P < 0.01) higher Brucella seroprevalence (13.5%) compared to those with no history of grazing in the park (4.9%). The significant association between abortion history and seropositivity observed in this study illustrates the potential economic significance of Brucella in cattle in this area. Hence, public awareness and further epidemiological studies of the disease in wildlife, livestock, and humans in the study area are of great importance.

TL;DR: The Ngezi Group in the Belingwe greenstone belt has been interpreted as continental basalts extruded onto, or oceanic crust obducted onto, a succession of stable-shelf sedimentary rocks that nonconformably overlie continental basement.
Abstract: Volcanic rocks of the Ngezi Group in the Belingwe greenstone belt have been interpreted as continental basalts extruded onto, or oceanic crust obducted onto, a succession of stable-shelf sedimentary rocks that nonconformably overlie continental basement. The volcanic succession locally contains quartzose sandstones, and the stratigraphy is unlike ocean crust. Primary volcanic and sedimentary structures indicate a shallow-subaqueous to subaerial origin. All structural features are compatible with later refolding of an autochthonous successon; there is no structural manifestation of obduction. These criteria refute an oceanic setting for the volcanic rocks; rather, they are consistent with an ensialic origin for the Ngezi Group.

TL;DR: In eastern Zimbabwe programmes need to provide greater access to circumcision services and the design and implementation of associated demand creation activities and HTC services need to consider how to increase reductions in partner numbers or increased condom use.
