Admission levels of asymmetric and symmetric dimethylarginine predict long-term outcome in patients with community-acquired pneumonia

During infection, there is an activation of the L-arginine-nitric-oxide pathway, with a shift from nitric oxide synthesis to a degradation of L-arginine to its metabolites, asymmetric and symmetric dimethylarginine (ADMA and SDMA). However, the prognostic implications for short-term or long-term survival remains unclear. We investigated the association of L-arginine, ADMA, and SDMA with adverse clinical outcomes in a well-defined cohort of patients with community-acquired pneumonia (CAP).; We measured L-arginine, ADMA, and SDMA in 268 CAP patients from a Swiss multicenter trial by mass spectrometry and used Cox regression models to investigate associations between blood marker levels and disease severity as well as mortality over a period of 6 years.; Six-year mortality was 44.8%. Admission levels of ADMA and SDMA (μmol/L) were correlated with CAP severity as assessed by the pneumonia severity index (r = 0.32, p < 0.001 and r = 0.56, p < 0.001 for ADMA and SDMA, respectively) and higher in 6-year non-survivors versus survivors (median 0.62 vs. 0.48; p < 0.001 and 1.01 vs. 0.85; p < 0.001 for ADMA and SDMA, respectively). Both ADMA and SDMA were significantly associated with long-term mortality (hazard ratios [HR] 4.44 [95% confidence intervals (CI) 1.84 to 10.74] and 2.81 [95% CI 1.45 to 5.48], respectively). The effects were no longer significant after multivariate adjustment for age and comorbidities. No association of L-arginine with severity and outcome was found.; Both ADMA and SDMA show a severity-dependent increase in patients with CAP and are strongly associated with mortality. This association is mainly explained by age and comorbidities.; ISRCTN95122877 . Registered 31 July 2006

Clinical information in drug package inserts in India

Background: It is widely recognized that accurate and reliable product information is essential for the safe and effective use of medications. Pharmaceutical companies are the primary source of most drug information, including package inserts. Package inserts are printed leaflets accompanying marketed drug products and contain information approved by the regulatory agencies. Studies on package inserts in India, in 1996, had shown that crucial information was often missing and they lacked uniformity. Aim: To assess the presentation and completeness of clinically important information provided in the currently available package inserts in India. Materials and Methods: Package inserts accompanying allopathic drug products marketed by pharmaceutical companies in India were collected. These package inserts were analyzed for the content of clinically important information in various sections. Statistical Analysis: The results were expressed as absolute numbers and percentages. Results: Preliminary analyses revealed that most package inserts did contain information under headings, such as, therapeutic indications, contraindications, undesirable effects, etc., listed in the Drugs and Cosmetics Rules 1945. The findings indicated considerable improvement in package inserts since 1996. However, on critical evaluation it was revealed that clinically important information was not well presented and was often incomplete. Information with regard to pediatric and geriatric use was present in only 44% and 13% of the package inserts, respectively. Only five of the inserts had information on the most frequent adverse drug reactions associated with the drug. Also, information on interactions and overdosage was often missing. Conclusion: Although the package inserts appear to have improved over the past decade there is still a definite need to further refine the clinical information contained, to minimize the risks to patients. This could be brought about by self-regulation on the part of the industry as well as by updating the relevant guidelines in line with those of developed countries

Efficacy of Google Form–based MCQ tests for formative assessment in medical biochemistry education

BACKGROUND: Biochemistry, being a vast and complex subject, can be challenging for Phase I MBBS students to comprehend and retain. Embracing rapidly evolving technology can facilitate a more accessible learning experience. In this study, we investigated the effectiveness of using Google Form–based multiple-choice question (MCQ) tests as a formative assessment tool after each biochemistry lecture series. The aim was to assess the improvement and gather feedback of Phase I MBBS students on the utility of this assessment tool. MATERIALS AND METHODS: This educational prospective longitudinal study was conducted by the Department of Biochemistry at a university-affiliated medical college and tertiary care hospital. The study included 150 Phase I MBBS students as participants. Google Form–based MCQ tests were implemented as educational interventions after each lecture series during the study period. The study compared the internal assessment (IA) MCQ marks of students before and after the implementation of the intervention. In addition, feedback questionnaires were collected from the students. RESULTS: There was a significant improvement in students’ scores between the first IA (mean ± standard deviation [SD], 8.16 ± 3.08) and second IA (mean ± SD, 17.64 ± 2.02) (P < 0.0001). According to students’ feedback, 149 out of 150 (99.3%) students found the use of Google Form–based MCQ tests as a formative assessment tool in the teaching–learning process to be highly beneficial and motivated them to engage in their biochemistry studies. CONCLUSION: With the shift toward competency-based medical education (CBME) in India, it is crucial for educators to embrace novel teaching–learning and evaluation approaches. Our study highlighted the efficacy of employing Google Form–based MCQ tests in enhancing students’ comprehension of the biochemistry subject, evaluating their scores and improving the overall quality of learning. Through this mode of assessment, teachers were able to provide targeted feedback on areas that required improvement, thereby enhancing the learning experience
