Objective: To evaluate the treatment outcome of second line drugs used in directly observed treatment, short-course (DOTS)-Plus regimen under Revised National Tuberculosis Control Program (RNTCP).
Materials And Methods: A prospective, observational study was carried out on multidrug resistant tuberculosis (MDR-TB) patients enrolled for DOTS-Plus regimen at TB and Chest Disease Department from January to December 2009. Demographic details, symptoms, sputum examination and adverse drug reactions were recorded in a case record form. Patients were followed up for 24 months. The data were analysed by Fisher's exact test and paired student's 't' test.
Results: Out of 130 patients, 51 (39%) were cured, 7 (5%) completed the treatment, 25 (19%) died, 30 (23%) defaulted and 17 (13%) failure. A significant increase in body weight (P < 0.0001) was observed at the end of the 24 months. Out of 89 patients with sputum culture conversion, majority (73) turned negative within first 3 months. Female gender (P < 0.05), conversion of sputum culture from positive to negative (P < 0.0001), and radiological improvement (P < 0.0001) were found to be positive predictors of a successful treatment outcome. While smoking habit (P < 0.05) and alcohol consumption (P < 0.05) were negative predictors of successful treatment outcome. Thirty five (26%) patients developed ADRs that required withdrawal of causal drug. The most common ADR was joint pain due to pyrazinamide (11) followed by neurological and psychiatric disturbances due to cycloserine (9).
Conclusion: The treatment outcome of standardized regimen in MDR-TB patients was low. The long duration of treatment and defaulters are major challenges for a successful outcome.

Introduction: Lorecivivint (LOR), a CDC-like kinase/dual-specificity tyrosine kinase (CLK/DYRK) inhibitor thought to modulate inflammatory and Wnt pathways, is being developed as a potential intra-articular knee osteoarthritis (OA) treatment. The objective of this trial was to evaluate long-term safety of LOR within an observational extension of two phase 2 trials.
Methods: This 60-month, observational extension study (NCT02951026) of a 12-month phase 2a trial (NCT02536833) and 6-month phase 2b trial (NCT03122860) was administratively closed after 36 months as data inferences became limited.
Adjunctive PCSK9 Inhibitor Evolocumab in the Prevention of Early Neurological Deterioration in Non-cardiogenic Acute Ischemic Stroke: A Multicenter, Prospective, Randomized, Open-Label, Clinical Trial.

Background: Early neurological deterioration (END) is associated with a poor prognosis in acute ischemic stroke (AIS). Effectively lowering low-density lipoprotein cholesterol (LDL-C) can improve the stability of atherosclerotic plaque and reduce post-stroke inflammation, which may be an effective means to lower the incidence of END. The objective of this study was to determine the preventive effects of evolocumab on END in patients with non-cardiogenic AIS.

Background: Patients with rectal cancer often experience adverse effects on urinary, sexual, and digestive functions. Despite recognised impacts and available treatments, they are not fully integrated into follow-up protocols, thereby hindering appropriate interventions. The aim of the study was to discern the activities conducted in our routine clinical practice outside of clinical trials.

In recent years, large amounts of researches showed that pulmonary embolism (PE) has become a common disease, and PE remains a clinical challenge because of its high mortality, high disability, high missed and high misdiagnosed rates. To address this, we employed an artificial intelligence-based machine learning algorithm (MLA) to construct a robust predictive model for PE. We retrospectively analyzed 1480 suspected PE patients hospitalized in West China Hospital of Sichuan University between May 2015 and April 2020.

Background: Due to improved treatment options, more SMA patients reach childbearing age. Currently, limited data on pregnant SMA patients is available, especially in relation to disease-modifying therapies (DMT). This case report helps to elucidate new approaches for future guidelines in the management of pregnancy and SMA.
