Method: Levels of Serum-CRP concentrations were deter-mined in 60 patients with pulmonary tuberculosis, 30 healthy volunteers and patients in follow-up after completion of antitubercular treatment (DOTS therapy). Results: Serum-CRP levels were found to be significantly higher in smear-positive group as compared with the follow-up patients and smear-negative control group. The values were 43.65 ± 23.68, 9.88 ± 5.23 and 4.04 ± 3.85 mg/L respectively (P Conclusion: Serum-CRP levels are significantly correlated with disease severity in patients with active pulmonary tuberculosis. Thus these findings from the present study would certainly add new criteria for early diagnosis of TB, which may lead to development of new strategies to treat TB.展开更多

Comprehension of Malaria risks is important to ensure compliance to prevention methods and treatment by the pregnant women and hence optimizes the pregnancy outcomes. The study was conducted in 2012 at three health facilities, Queen Elizabeth Central Hospital, Ndirande health Centre and St. Joseph Mission Hospital in Malawi. The study design was descriptive and utilized quantitative data collection and analysis methods on a random sample of 316 antenatal mothers. The study targeted antenatal mothers who were aged between 15 and 49 years, in the gestation period of 28 to 36 weeks and able to converse in English or vernacular language. A structured questionnaire was used to collect data which were analyzed using SPSS version 16.0. Most of the participants (79.4%, n = 251) knew the risk factors of malaria during pregnancy but very few (18.4%, n = 58) knew about intermittent prevention treatment despite taking SP as prescribed. The motivation factors for taking SP were husband support and the desire to protect their babies and themselves from Malaria. Although the comprehension of the intermittent prevention treatment among the women was low, the women were motivated to adhere to the treatment when instructed by the healthcare workers due to the desire for good health for themselves and their unborn babies. Husbands were the most significant other that motivated the pregnant women to adhere to treatment. Results show that there is a need for healthcare workers to facilitate comprehension of intermittent prevention treatment among pregnant mothers.展开更多
Several related substances were detected at trace level in (2R)-2,3-dihydro-2-methyl-6-nitro-2-[[4-[4-[4-(trifluoromethoxy)phenoxy]-1-piperidinyl] phenoxy] methyl]imidazo[2, 1-b]oxazole drug substance by a newly devel...Several related substances were detected at trace level in (2R)-2,3-dihydro-2-methyl-6-nitro-2-[[4-[4-[4-(trifluoromethoxy)phenoxy]-1-piperidinyl] phenoxy] methyl]imidazo[2, 1-b]oxazole drug substance by a newly developed high-performance liquid chromatography method. All related substances were characterized rapidly but some impurities were found to be intermediates. Proposed structures were further confirmed by characterization using NMR, FT-IR, and HRMS techniques. Based on the spectroscopic data;unknown related sub-stances were characterized as 1-(Methylsulfonyl)-4-[4-(trifluoromethoxy) phenoxy]piperidine;4-{4-[4-(Tri-fluoromethoxy)-phenoxy]piperidin-1-yl}phenol and 4-{4-[4-(trifluoromethoxy)phenoxy]piperidin-1-yl}phenyl methane sulfonate;4-Bromophenyl methane sulfonate, Ethyl 3,6-dihydro-1(2H)-pyridine carboxylate, (2S)-3-(4-Bromophenoxy)-2-hydroxy-2-methylpropyl methane sulfonate, (2S)-3-(4-Bromophenoxy)-2-methylpropane-1,2-diyldimethane-sulfonate, (2S)-2-Methyl-3-(4-{4-[4-(trifluoromethoxy) phenoxy]-piperidin-1-yl} phenoxy)-propane-1,2-diyldimethane sulfonate, (S)-3-(4-Bromophenoxy)-2-methyl-propane-1,2-diol and corresponding Enantiomer, (2R)-2-[(4-Bromo-phenoxy)methyl]-2-methyloxirane and (2R)-2-[(4-bromophenoxy)methyl]-2-methyl-6-nitro-2,3-dihydroimidazo[2,1-b][1,3]oxazole. A possible mechanism for the formation of these related substances is also proposed.展开更多

The project generated promising results in policy development, strengthening of TB control systems, patient treatment success,funds management, and the introduction of legislation. In light of the global TB epidemic and control environment, it is useful to review the TB control priorities of the project, summarize the achievements and experiences around its implementation.展开更多
