We conducted an audit of patients’ hospital records from a STIs clinic at Monkey Bay community hospital in Mangochi District (Malawi) covering a period from January 2019 to June 2019 (18 months). Data was tabulated in excel and analyses were made based on sex, age, male circumcision status, pregnancy and the pattern of STIs diagnosed within the chosen study period. A total number of 659 clients presented at STI clinic of Monkey Bay community hospital between January 2018 and June 2019. Out these clients, 409 (62%) were females and 250 (38%) were males. Most of the patients were in the age range of 25 years or above (447, 68%). Majority of the patients were HIV negative (523, 79%). Out of the 250 males, 113 (45%) were circumcised. Among female patients 56 of the 409 (14%) were pregnant. The most common presentations for all cases put together were lower abdominal pain (253, 38%), then urethral discharge (189, 29%), abnormal vaginal discharge (141, 21%), genital ulcer disease (64, 10%), in that order. Syphilis, genital warts, inguinal bubo and scrotal swelling were less common. The most common presentation in males was urethral discharge (178, 71%), while in females it was lower abdominal pain (214, 52%). Our audit showed that in Mangochi (Malawi) sexually transmitted diseases of various types are more common among young adults, females and uncircumcised men. There was no much difference in the percentage of STI’s between HIV positive and HIV negative people. These results point to an alarmingly high level of risky sexual behaviors among sexually active age groups in this part of Malawi, a country which still has one of the highest HIV prevalence in sub-Saharan Africa. This calls for continued and better research and control for transmission of STIs in the district.展开更多

Mediator-less two chamber H-type MFCs were prepared using rumen fluid as anode inocula to convert finely ground pine tree (Avicel) at 2% (w/v) to electricity.

Supplementation of Doraji roots powder to MFC anode chamber increased power generation and CO2 production. Over the 10d experimental period, power density normalized to anode surface area were between 17.0 and 37.7 with average of 32.5 mW/m2 in Doraji MFCs, and between 16.8 and 19.8 with average of 18.2 mW/m2 in control group. CO2 production increased and methane to CO2 ratio decreased in Doraji root treatment comparing to control group.
