GRADE-ADOLOPMENT of clinical practice guideline for postmenopausal osteoporosis management-a Pakistani context.

Unlabelled: Due to its high prevalence, we aimed to create postmenopausal osteoporosis clinical practice guideline via GRADE-ADOLOPMENT for Pakistan. We recommend a higher dose (2000-4000 IU) of vitamin D for osteoporotic patients who are old, have malabsorption, or are obese. The guideline will help standardize care provision and improve health care outcomes for osteoporosis.

Evaluation of CSF kappa free light chains for the diagnosis of multiple sclerosis (MS): a comparison with oligoclonal bands (OCB) detection via isoelectric focusing (IEF) coupled with immunoblotting.

This study was done to evaluate the diagnostic accuracy of cerebrospinal fluid kappa free light chain (KFLC) for diagnosis of multiple sclerosis, against isoelectrofocusing (IEF) to detect oligoclonal bands (OCB) as gold standard. 64 cases were divided into positive and negative based on the OCB results. Diagnostic accuracy was calculated for the 1 mg/L cut-off.

Publication dynamics: what can be done to eliminate barriers to publishing full manuscripts by the postgraduate trainees of a low-middle income country?

Objectives: This study aimed to determine the publication rate of free paper abstracts presented by the postgraduate (PG) trainees and determine the reasons for non-publication. A mixed methods study was conducted. PG trainees presenting free papers at the at the Pakistan Society of Chemical Pathologist conferences from 2012 to 2018 were included.

Development of a virtual classroom for pre-analytical phase of laboratory medicine for undergraduate medical students using the Delphi technique.

Background: Amongst the pre-analytical, analytical, and post-analytical phase of laboratory testing, pre-analytical phase is the most error-prone. Knowledge gaps in understanding of pre-analytical factors are identified in the clinical years amongst undergraduate students due to lack of formal teaching modules on the pre-analytical phase. This study was conducted to seek experts' consensus in Clinical Chemistry on learning objectives and contents using the Delphi technique with an aim to develop an asynchronous virtual classroom for teaching pre-analytical factors of laboratory testing.

Development and validation of standard and real patient gallstone library using Fourier transform infra-red spectroscopy.

Background: Analysis of the constituents of gallstones using various spectroscopic techniques assists in identification of the pathogenesis of gallstones. In the current study, using Fourier Transform Infra-Red (FTIR) Spectroscopy, a Gallstone Standard Library (GSL) and a Gallstone Real Patients' Library (GRPL) were developed and validated for gallstone composition analysis.

Methods: The study was conducted at the Department of Pathology & Laboratory Medicine, Aga Khan University, Pakistan.

Ups and Downs of COVID-19: Can We Predict the Future? Local Analysis with Google Trends for Forecasting the Burden of COVID-19 in Pakistan.

Background: We aim to study the utility of Google Trends search history data for demonstrating if a correlation may exist between web-based information and actual coronavirus disease 2019 (COVID-19) cases, as well as if such data can be used to forecast patterns of disease spikes.

Patients & Methods: Weekly data of COVID-19 cases in Pakistan was retrieved from online COVID-19 data banks for a period of 60 weeks. Search history related to COVID-19, coronavirus and the most common symptoms of disease was retrieved from Google Trends during the same period.

Effect of physical activity and vitamin D compared with vitamin D alone on muscle strength, back flexibility and aerobic activity in patients with chronic kidney disease: A comparative study from Pakistan.

Background And Objectives: To compare the differences in musculoskeletal health with vitamin D alone in comparison with vitamin D with physical activity (PA) among chronic kidney disease (CKD) patients.

Methods And Study Design: An open labeled, randomized, controlled trial was conducted at two tertiary care centers in Pakistan. Patients with CKD stage 2-4 and vitamin D deficiency (<20 ng/mL) were recruited in the trial.

SARS-CoV-2 vaccine response in CAR T-cell therapy recipients: A systematic review and preliminary observations.

Evolving data suggest that SARS-CoV-2 vaccine responses are blunted in allogeneic hematopoeitic cell transplant (HCT) recipients. Responses to the vaccine in chimeric antigen receptor T-cell (CAR-T) therapy are unknown and are likely to be even more diminished. We manually searched vital databases and identified 5 studies that have so far reported COVID-19 vaccine response in a total of 70 CAR-T recipients.

Role of Gut Microbiome in COVID-19: An Insight Into Pathogenesis and Therapeutic Potential.

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulted in an unprecedented global crisis. Although primarily a respiratory illness, dysregulated immune responses may lead to multi-organ dysfunction. Prior data showed that the resident microbial communities of gastrointestinal and respiratory tracts act as modulators of local and systemic inflammatory activity (the gut-lung axis).

State of the CAR-T: Risk of Infections with Chimeric Antigen Receptor T-Cell Therapy and Determinants of SARS-CoV-2 Vaccine Responses.

Chimeric antigen receptor T cell (CAR-T) therapy has shown unprecedented response rates in patients with relapsed/refractory (R/R) hematologic malignancies. Although CAR-T therapy gives hope to heavily pretreated patients, the rapid commercialization and cumulative immunosuppression of this therapy predispose patients to infections for a prolonged period. CAR-T therapy poses distinctive short- and long-term toxicities and infection risks among patients who receive CAR T-cells after multiple prior treatments, often including hematopoietic cell transplantation.

Herpetic optic perineuritis presenting as classic abducens nerve palsy.

Optic perineuritis is a rare manifestation of herpes zoster ophthalmicus (HZO). Relative afferent pupillary defect (RAPD) is an important early clue to an impending nerve involvement, and robust clinical examination allows early detection of such rare metachronous manifestation of cutaneous HZ and institution of timely management for such sight-threatening conditions.

Small Centers with Big Ventures: Autologous Stem Cell Transplantation Survival Data.

We present the first-ever autologous stem cell transplantation (ASCT) outcome data from a secondary-care healthcare facility. Albeit exact details of patient and disease characteristics and co-morbidity scores for all patients are not available, the engraftment and survival data is very similar to those published from large tertiary-care cancer centres, both regionally and internationally. Transplant Related Mortality (TRM) of 3.

Pegylated Filgrastim Versus Filgrastim for Stem Cell Mobilization in Multiple Myeloma After Novel Agent Induction.

Background: The current standard of care for transplant-eligible myeloma patients is novel agent-based induction, followed by high-dose chemotherapy and autologous stem cell rescue. Chemo-mobilization of peripheral blood CD34 stem cells (PBSCs) with pegylated filgrastim (pegfilgrastim), a sustained-duration formulation of filgrastim, has been used as an alternative to filgrastim in several studies involving heterogeneous cohorts of lymphoma and multiple myeloma (MM) patients and shown to be equivalent in PBSC yield and cost-effectiveness. The present study focused on the efficacy of pegfilgrastim in PBSC mobilization compared with filgrastim exclusively after novel agent-based induction in a homogeneous group of MM patients.

Development and Pilot Testing of an Objective Structured Clinical Examination for Obstructive Sleep Apnea.

Objective Our aim was (1) to develop an objective structured clinical examination (OSCE) for obstructive sleep apnea (OSA) and (2) to test the reliability and evaluate the feasibility of this OSCE while assessing residents' clinical skills in multiple core competencies via the standardized patient methodology. Study Design Development of assessment tool. Setting Johns Hopkins Medicine Simulation Center.

Is tocilizumab a potential therapeutic option for refractory unicentric Castleman disease?

Castleman disease is a rare lymphoproliferative disorder with 2 distinctly defined clinical forms. While multicentric Castleman disease (UCD) poses a potential therapeutic challenge, unicentric variant has historically been considered curable with surgical resection. Hence, little is known to guide management of patients with UCD, refractory to surgical resection and combination chemotherapy.
