Mobile healthcare simulation units: a narrative review.

For healthcare professionals working and living in geographical isolation, there are few opportunities to maintain skills and knowledge, and to update themselves with recent advances in care compared to their citydwelling peers. It is known that within a short period and limited practice, clinical skills erode. A mobile healthcare simulation unit provides high-quality, technologicallyenhanced, convenient, and affordable training for healthcare professionals under expert supervision in any remote setting. The current narrative review was planned to summarise the outcomes and challenges related to developing and effectively utilising mobile healthcare simulation units as experienced globally. A literature search was performed on PubMed, Google Scholar and Cochrane databases for relevant articles published between 2000 and 2020, which resulted in 18 articles that were shortlisted and three major themes. The identification of common strengths, weaknesses and challenges will be a starting point for those engaged in planning and operating such a centre in any location.

PakSurg: The first trainee-lead model for multicenter surgical research collaboration in Pakistan.

We describe creation and piloting of the PakSurg Collaborative, devised via integration of existing trainee-led collaborative models in the United Kingdom with the resource-limited surgical care in Pakistan. This is the first trainee-lead surgical research collaborative in Pakistan, established by the student-lead Surgery Interest Group from the Aga Khan University. The project involved creation of a model that included a steering committee comprising of five teams which worked in conjunction with collaborators from multiple hospitals. To facilitate this collaboration, a comprehensive and cost-efficient study management pathway was developed. The PakSurg Collaborative has the potential to deliver methodologically robust, high-quality, multicenter surgical evidence from Pakistan. This nationally representative data could inform evidence-based surgical guidelines, potentially translating into improved outcomes for patients undergoing surgery.

A Review of Coronaviruses Associated With Kawasaki Disease: Possible Implications for Pathogenesis of the Multisystem Inflammatory Syndrome Associated With COVID-19.

Multisystem Inflammatory Syndrome in Children (MIS-C), representing a new entity in the spectrum of manifestations of COVID-19, bears symptomatic resemblance with Kawasaki Disease (KD). This review explores the possible associations between KD and the human coronaviruses and discusses the pathophysiological similarities between KD and MIS-C and proposes implications for the pathogenesis of MIS-C in COVID-19. Since 2005, when a case-control study demonstrated the association of a strain of human coronavirus with KD, several studies have provided evidence regarding the association of different strains of the human coronaviruses with KD. Thus, the emergence of the KD-like disease MIS-C in COVID-19 may not be an unprecedented phenomenon. KD and MIS-C share a range of similarities in pathophysiology and possibly even genetics. Both share features of a cytokine storm, leading to a systemic inflammatory response and oxidative stress that may cause vasculitis and precipitate multi-organ failure. Moreover, antibody-dependent enhancement, a phenomenon demonstrated in previous coronaviruses, and the possible superantigenic behavior of SARS-CoV-2, possibly may also contribute toward the pathogenesis of MIS-C. Lastly, there is some evidence of complement-mediated microvascular injury in COVID-19, as well as of endotheliitis. Genetics may also represent a possible link between MIS-C and KD, with variations in FcγRII and IL-6 genes potentially increasing susceptibility to both conditions. Early detection and treatment are essential for the management of MIS-C in COVID-19. By highlighting the potential pathophysiological mechanisms that contribute to MIS-C, our review holds important implications for diagnostics, management, and further research of this rare manifestation of COVID-19.

Low-cost peer-taught virtual research workshops for medical students in Pakistan: a creative, scalable, and sustainable solution for student research.

BACKGROUND: Pakistan has not been a major contributor to medical research, mainly because of the lack of learning opportunities to medical students. With the increase in online learning systems during COVID-19, research related skills can be taught to medical students via low-cost peer taught virtual research workshops. AIM OF THE STUDY: To assess the effectiveness of a comprehensive low-cost peer-taught virtual research workshops amongst medical students in Pakistan. METHODS: This quasi-experimental study assessed the effectiveness of five virtual research workshops (RWs) in improving core research skills. RWs for medical students from across Pakistan were conducted over Zoom by medical students (peer-teachers) at the Aga Khan University, Pakistan, with minimal associated costs. The content of the workshops included types of research, ethical approval and research protocols, data collection and analysis, manuscript writing, and improving networking skills for research. Improvement was assessed via pre-and post-quizzes for each RW, self-efficacy scores across 16 domains, and feedback forms. Minimum criteria for completion of the RW series was attending at least 4/5 RWs and filling the post-RW series feedback form. A 6-month post-RW series follow-up survey was also emailed to the participants. RESULTS: Four hundred medical students from 36 (/117; 30.8%) different medical colleges in Pakistan were enrolled in the RWs. However, only 307/400 (76.75%) medical students met the minimum requirement for completion of the RW series. 56.4% of the participants belonged to the pre-clinical years while the rest were currently to clinical years. The cohort demonstrated significant improvement in pre-and post-quiz scores for all 5 RWs (p <  0.001) with the greatest improvement in Data Collection and Analysis (+ 34.65%), and in self-efficacy scores across all domains (p <  0.001). 166/307 (54.1%) participants responded to the 6 months post-RWs follow-up survey. Compared to pre-RWs, Research involvement increased from 40.4 to 62.8% (p <  0.001) while proportion of participants with peer-reviewed publications increased from 8.4 to 15.8% (p = 0.043). CONCLUSION: Virtual RWs allow for a wide outreach while effectively improving research-related knowledge and skills, with minimal associated costs. In lower-middle-income countries, virtual RWs are a creative and cost-effective use of web-based technologies to facilitate medical students to contribute to the local and global healthcare research community.

Case Study of Pediatric Cerebral Sinus Venous Thrombosis Center of a Low Middle-Income Country.

Pediatric cerebral venous sinus thrombosis (CVST) is rare but a potentially fatal disease requiring its understanding in local setting. In this study, we observed the clinical course, management, and outcome of pediatric patients with sinus thrombosis in a tertiary care center at Pakistan. Patients between age 0 to 18 years of both genders diagnosed with sinus thrombosis during 2011 to 2020 were included. Data was collected through in-house computerized system and SPSS version 19 was used for analysis. Of 143492 pediatric admissions, 32 (21 males and 11 females) patients with a median (IQR) age of 4.5 years (0-16) had CVST. This is equivalent to 18.5 CVST events per million pediatric admissions. Adolescents were mostly affected, and the overall mortality was 7%. Primary underlying disorders were infections (59%), hematological neoplasms (12.5%), thrombotic thrombocytopenic purpura (3%) and antiphospholipid syndrome (3%). Activated protein C resistance (44%) was the most common inherited thrombophilia. Twenty-one (66%) patients were anemic with a mean (±SD) hemoglobin of 9.0 g/dL (±2.3). Regression analysis showed a positive association of anemia with multiple sinus involvement (P-value 0.009) but not with duration of symptoms (P-value 0.344), hospital stay (P-value 0.466), age (P-value 0.863) or gender (P-value 0.542) of the patients. SARS-COV2 was negative in patients during 2020. Adolescents were primarily affected by sinus thrombosis and infections was the predominant risk factor for all age groups, with a low all-cause mortality. A high index of clinical suspicion is required for prompt diagnosis and intervention.

Intraoperative hypothermia in patients undergoing Total knee arthroplasty: a cross-sectional study from a developing country.

BACKGROUND: Intraoperative hypothermia is associated with various risk factors, morbidity, and mortality in patients undergoing total knee arthroplasty (TKA), increasing the emotional and financial burden on patients. This study aimed to identify risk factors of intraoperative hypothermia in patients undergoing TKA. MATERIALS AND METHODS: All adult patients (⩾18 years) who underwent TKA from January 2016 to December 2017 at a tertiary-care hospital in Pakistan were included in this retrospective, cross-sectional study. Temperature < 36 °C was defined as hypothermia. RESULTS: The study included 286 patients (77.6% female) with a mean age of 61.4 ± 10.4 years. The overall proportion of intraoperative hypothermia was 26.6%. Of the total patients, 66.1% underwent bilateral TKA whereas 33.9% underwent unilateral TKA. 73.8% of the patients were ASA Level 2. Only 13.3% of patients had postoperative hypothermia. CONCLUSION: Intraoperative hypothermia was significantly associated with age, bilateral procedure, ASA level and postoperative hypothermia in patients undergoing TKA. The surgeon and the operative team should be aware of the risk factors and the adverse outcomes associated with intraoperative hypothermia, especially in resource constrained settings to plan preventive strategies. TRIAL REGISTRATION: This study was retrospectively registered on ClinicalTrials.gov on 3rd October 2020. The registration ID is NCT04575246 .

Risk Assessment and Outcome of Venous Thromboembolism in Pediatric Population in an Academic Care Center of a Low-Middle Income Country.

Venous thromboembolism (VTE) is a recognized complication of hospital stay in young patients in many developed countries, but such an information is largely unavailable from a low middle-income country (LMIC). This study aimed at identifying the frequency, risk factors, treatment options and outcome of deep venous thrombosis/pulmonary embolism (DVT/PE) in pediatric population in a tertiary care center from a LMIC. International classification of disease, ninth revision (ICD-9) was used to identify VTE in patients aged 0-18 years during January 2011 to September 2019. In-house computerized system was used to collect data for demographics, clinical and laboratory details. SPSS version 19 was used to analyzed data. The study was approved by Institutional ethical review committee (3872-Pat-ERC-15). During the study period, 134617 pediatric patients were hospitalized, DVT/PE was observed in 77 unique patients (47 males and 30 females) with a median (IQR) age of 14 (5-16) years equivalent to 5.9 VTE events /10,000 hospital admissions. Malignancy, community acquired infections and autoimmune diseases were the predominant risk factors (75%) in adolescent age-group while surgery for congenital heart anomalies was the primary reason (71%) in infants. Overall, lower extremity thrombosis was the most frequent (51%) followed by pulmonary embolism (25%). and upper extremity thrombosis (24%). Enoxaparin and unfractionated heparin were mainly used to treat VTE and all-cause mortality was 13% in the cohort studied. We observed substantial VTE events in pediatric patients during their hospital stay in a tertiary care center of a low-middle income country.

Student-led surgical research network: Enhancing medical student research opportunities.

The current paper was planned to describe a student-led surgical research network established by the Research Division of the Surgery Interest Group at the Aga Khan University, Karachi. The project involved the creation of a collaborative network to provide opportunities to medical students to work with faculty on research projects. Over 25 students were directly connected with faculty and research mentors to work on research projects in the surgical specialty of their choice. The initiative of establishing a student-led surgical research network was successfully implemented and provided medical students with novel research opportunities by helping bridge the gap between the students and the faculty.

Peer-taught virtual research workshops for surgical residents: Protocol for a novel and sustainable solution to improving surgical research in Pakistan.

OBJECTIVE: To generate a protocol describing the methodology for a study assessing the effectiveness of a comprehensive series of peer-taught online research workshops for surgical residents across Pakistan in terms of improving research-related knowledge and skills, and long-term research involvement and output. METHODS: The quasi-experimental study will consist of a series of six online research workshops conducted over Zoom for surgical residents across Pakistan. An online sign-up form will be circulated on social media to current surgical residents throughout Pakistan. Curricular content covered in the workshops will be developed in collaboration with experienced research faculty at the Departments of Surgery and Community Health Sciences at the Aga Khan University Hospital, Karachi. Facilitators of the workshops will be current surgical residents with a solid track record of research involvement at the hospital. Improvement in research-related knowledge and skills will be assessed through pre- and post-tests for each workshop. A post-series feedback form will assess satisfaction with the organisation, content relevance, peer-teaching and online delivery of the workshops. Long-term research involvement and output will be assessed by follow-up surveys at 6 months and 1 year post-workshop. All data-collection will be done via Google Forms. For ethical purposes, informed consent will be taken from participants prior to enrolment; data will be collected using a unique identifier number to maintain anonymity; and the only incentive provided to participants will be a Certificate of Completion for the research workshop series. RESULTS: We expect that surgical trainees participating in the series of six research workshops will demonstrate a highly significant percentage improvement (p<0.001) in the pre- and post-tests for each of the six core research competencies taught. On post-series feedback, we expect the majority of participants (>80%) to rate the overall organisation, effectiveness of online mode of instruction, and relevance to surgical training of the workshops as excellent/good. We also expect that most participants (>80%) would strongly agree/agree that peer-education is an effective model of teaching in research workshops. Finally, we expect statistically significant improvement (p<0.05) in research involvement and output in terms of publications as assessed in the 6 months and 1year post-workshop follow-up surveys. CONCLUSIONS: In light of the ever-growing need for academic surgeons in Pakistan, this research protocol details a comprehensive strategy for research capacity-building among surgical trainees across the country. By equipping trainees with the knowledge and skills to conduct high-quality research, virtual research workshops provide a novel, grassroots-level and sustainable solution for addressing the surgical research crisis in Pakistan.

Progression of Acute Kidney Injury to Chronic Kidney Disease in Sepsis Survivors: 1-Year Follow-Up Study.

BACKGROUND: Despite the fact that septic acute kidney injury (AKI) is considered to be reversible, it can result in permanent kidney damage. Unfortunately, there is a scarcity of long-term follow-up studies highlighting progression to chronic kidney disease (CKD) in sepsis survivors. To address this issue, we conducted this study to assess the development of CKD in sepsis patients with AKI, and to identify risk factors associated with its development. METHODS: This retrospective cohort study evaluated medical records of patients admitted at the Aga Khan University Hospital between January-December 2017 with the diagnosis of sepsis and subsequent development of acute kidney injury (AKI). One-year follow-up data was then analyzed to determine whether the AKI resolved or progressed to chronic kidney disease. RESULTS: 1636 sepsis patients were admitted during the study period, out of which 996 (61%) met the inclusion criteria. 612 (61%) developed AKI during the admission. Mortality rate in the AKI group was 44% (n = 272). After 1 year, 47 (19%) patients eventually went on to develop CKD and 81% (n = 195) recovered fully. Risk factors for development of CKD were age ≥ 60 years (p = <0.001), diabetes (p = <0.001), hypertension (p = 0.001) and history of ischemic heart disease (p = <0.001). CONCLUSION: Mortality rates in sepsis are alarmingly high and even those patients who manage to survive are at risk of developing permanent organ dysfunction. Our study revealed that almost one fifth of all septic AKI survivors went on to develop chronic kidney disease within 1 year, even when AKI was not severe. We recommend that clinicians focus on early recovery of renal function, irrespective of AKI severity, and ensure robust follow-up monitoring to reduce long term morbidity and mortality associated with this devastating illness.
