Background: Various studies have reported culture conversion at two months as a predictor of successful treatment outcome in multidrug-resistant tuberculosis (MDR-TB).
Objectives: The present study was conducted with the aim to evaluate the rate and predictors of culture conversion at two months in MDR-TB patients.
Methods: All confirmed pulmonary MDR-TB patients enrolled for treatment at Lady Reading Hospital Peshawar, Pakistan from 1 January to 31 December 2012 and met the inclusion criteria were reviewed retrospectively. Rate and predictors of culture conversion at two months were evaluated.
Results: Eighty seven (53.4%) out of 163 patients achieved culture conversion at two months. In a multivariate analysis lung cavitation at baseline chest X-ray (P = 0.006, OR = 0.349), resistance to ofloxacin (P = 0.041, OR = 0.193) and streptomycin (P = 0.017, OR = 0.295) had statistically significant (P<0.05) negative association with culture conversion at two months.
Conclusion: A reasonable proportion of patients achieved culture conversion at two months. Factors negatively associated with culture conversion at two months can be easily identified either before diagnosis or early in the course of MDR-TB treatment. This may help in better care of individual patients by identifying them early and treating them vigorously.

Background: Higher than standard doses of rifampicin could improve the treatment outcome of drug-susceptible tuberculosis without compromising the safety of patients.
Methods: We performed a systematic review of prospective clinical studies including adults with pulmonary and extrapulmonary TB receiving rifampicin doses above 10mg/kg/day. We extracted the data on overall adverse events (AE), hepatic AE, sputum culture conversion (SCC) at week 8, recurrence, mortality, and pharmacokinetics.

Background: In the face of increasing Mild Cognitive Impairment(MCI) and Dementia rates among aging populations, understanding the factors shaping the non‐normal cognitive decline is crucial. Leveraging the Clinical Dementia Rating (CDR) data, this study has a dual focus. (1) It utilizes CDR to aid early MCI diagnosis by investigating factors contributing to transition from Questionable‐ to Low‐ AD.

Background: Regional distribution of neurofibrillary tangles consisting of hyperphosphorylated tau correlates strongly with the progression of Alzheimer’s disease (AD). Misfolded proteopathic tau templates the conversion of naive tau into a pathological state in a prion‐like fashion, which underlies the spreading of tau pathology in the brain. Whether hyperphosphorylation triggers tau aggregation or hyperphosphorylation occurs after aggregation is under much debate.

The conversion of organic matter to methane through anaerobic digestion (AD) process can be enhanced by different materials. However, literature reports show inconsistent results on the effect of materials in different AD systems. In this study, we evaluated the influence of the inoculum's activity on methane production (MP) efficiency in the presence of different materials (activated carbon (AC), magnetite (Mag), and zeolite (Zeo)).

The favorable impacts of Bacillus coagulans or Yeast culture on broiler production performance and immune function have been acknowledged. However, the effects of the combined of them (BcYc) on the broilers remained unknown. Thus, the current research aimed to assess the effects of BcYc (at dosages of 0, 200, 300, and 400 mg/kg) on growth performance, plasma biochemical indices, antioxidant capacity, and intestinal morphology and microbial composition in broilers.
