A student driven WBA model was introduced and perception evaluation of this teaching method was done subsequently by taking feedback from the faculty as well as the postgraduate trainees (PGs) of a residency program. Methods Descriptive mixed method study was conducted. A WBA program was designed for PGs in Chemical Pathology on MOODLE and forms utilized were Case-based discussion (CBD), Direct Observation of Practical Skills (DOPS) and Evaluation of clinical events (ECE). Consented assessors and PGs were trained on WBA through a workshop. Pretest and post-test to assess PGs knowledge before and after WBA were conducted. Every time a WBA form was filled, perception of PGs and assessors towards WBA, time taken to conduct single WBA and feedback were recorded. Faculty and PGs qualitative feedback on perception of WBA was taken via intervi...

The heterogeneous disease itself and its complex treatment leads to various bone-affecting complications that make breast cancer patients more vulnerable to bone fractures. Vitamin D deficiency among these women worsens the condition and promotes breast cancer growth. Thus, the purpose of the study was to assess serum levels of 25-hydroxyvitamin D (25OHD) and bone markers in women suffering from breast cancer. Serum levels of 25OHD, alkaline phosphatase (ALP), bone specific ALP, calcium (Ca), phosphorus (P), magnesium (Mg), albumin (Alb) and beta carboxyl terminal collagen crosslink (β-CTx) were analyzed in 201 histological diagnosed patient volunteers from breast cancer clinic. Vitamin D insufficiency was present among the total study population and deficiency was particularly observed among women with metastases. These patients had significantly increased serum levels of β-CTx and bone specific ALP w...

The purpose of this study was to validate the performance of Corona-Score in a cohort of Pakistani patients pursuing care for suspected infection. Methods After seeking institution's ethical committee exemption, results of serum lactate dehydrogenase (LDH), C-reactive protein (CRP), ferritin, absolute lymphocyte and neutrophil counts, chest x-ray findings and demographics of suspected COVID-19 cases with respiratory symptoms were recouped from electronic medical record. The pre-validated score as proposed by Kurstjens S et al., was calculated. The subjects were divided into SARS-CoV-2 positive and negative on the basis of reverse transcription-polymerase chain reaction (RT-PCR) findings. Median and interquartile range (IQR) was calculated for the score in the two groups and the difference was assessed using the independent sample median test. Receiver o...

At our institute, grand rounds in the Department of Surgery include an original research presentation by residents. The publication of the research work acts as a measure of its success. In this study we analyzed the outcome of this activity and review factors affecting their progression to publication. We conducted a retrospective review of a prospectively maintained database of all presentations made at the Surgical Grand Round at a University Hospital from January 2001 to December 2010. Presentations with incomplete follow up records were excluded from analysis. A Publication-Presentation Index (PPI) was used to evaluate outcomes of SGRs and to study factors influencing outcomes. Differences in PPI in each category were calculated using the chi square test. Total of 470 presentations were made. Majority presented retrospective studies (73%). Majority of the presentations were made by junior residents (year 1-3, 62%). Following presentation, 279 (59.4%) studies were presented at a national conference, 80 (17%) were presented at an international forum while only 99 (21.1%) studies were published. Mean presentation to publication time was 34.8 months. Study design, level of resident, section of surgery, sample size and national/international presentation were associated with conversion to a publication (all p < 0.05). Overall PPI was 0.32. Randomized controlled trials had the highest PPI (0.67). The proportion of SGR presentations converted into national/international presentations and/or publications was found to be low. The PPI has a potential to be used as a tool to study the association of presentation to publication.
