This study was carried out in order to assess the sensitivity and specificity of visual inspection after acetic acid staining (VIA) using Papanicolaou smear as the gold standard screening method for cervical premalignant lesion. Two hundred and twenty (220) consecutive and consenting women ages 20 -70 years, attending Federal Medical Centre, Ido-Ekiti, Ekiti State, were recruited. Relevant data were collected using interviewer-administered semi-structured questionnaires. In conclusion, the prevalence of pre-malignant lesion of cervical cancer is high in this study. It is therefore recommended that awareness of cervical cancer and its screening should be improved through health education campaigns. VIA can serve as an alternative to Papanicolaou smear in resource-limited countries, since it has high level of specificity and sensitivity as Papanicolaou smear.

Leptospirosis is a zoonotic neglected tropical disease with a worldwide distribution caused by the pathogenic spirochetes of the genus Leptospira. Despite being a widespread disease in tropical regions, it has never been considered in the routine diagnostic panel for febrile patients. This study determined seropositivity and factors associated with Leptospira antibodies among febrile adult patients in Mwanza, Tanzania. The cross-sectional study involving 296 febrile patients attending different outpatient clinics in Mwanza region was conducted between May and July 2019. Detection of Leptospira serovars antibodies was done using a microscopic agglutination test (MAT). Descriptive analysis was done using STATA version 13. The median age of the febrile patients was 32 (IQR: 24–45 years). Out of 296 patients, 36 (12.16%, 95%CI: 8–15) were seropositive for Leptospira antibodies. Common circulating serovars were Sokoine 28 (9.45%), followed by Lora 12 (4.05%) and Grippotyphosa 2 (0.67%). In the multivariable logistic regression analysis, the odds of being Leptospira seropositive were significantly higher with increased age (aOR: 1.03, 95%CI 1.00–1.07, p = 0.03). About one tenth of febrile patients in Mwanza were seropositive for Leptospira antibodies and this was significantly associated with age. With the decline of malaria fever in endemic areas, other causes of febrile illness like Leptospiral spp. should be considered in the routine diagnostic panel for febrile patients.

This study was conducted to investigate the rate of soil respiration from a recovering forest of the tropics and its relationship with changes in environmental factorsafter years of deforestation. Soil respiration measurement was conducted using the continuous open flow chamber technique connected to a multi gashandling unit and infrared gas analyser, while the forest biomass and soil properties were quantified using the Kjeldahl method and Walkley-black wet oxidation technique. The average means soil respiration rate were 341.23, 383.07, 340.30, 308.12, 286.07, 256
