The mystery of COVID-19 reinfections: A global systematic review and meta-analysis

Background: As the COVID-19 pandemic rages on, reports on disparities in vaccine roll out alongside COVID-19 reinfection have been emerging. We conducted a systematic review to assess the determinants and disease spectrum of COVID-19 reinfection.Materials and methods: A comprehensive search covering relevant databases was conducted for observational studies reporting Polymerase Chain Reaction (PCR) confirmed infection and reinfection cases. A quality assessment tool developed by the National Institute of Health (NIH) for the assessment of case series was utilized. Meta-analyses were performed using RevMan 5.3 for pooled proportions of findings in first infection and reinfection with a 95% confidence interval (CI).Results: Eighty-one studies reporting 577 cases were included from 22 countries. The mean age of patients was 46.2 ± 18.9 years and 179 (31.0%) cases of comorbidities were reported. The average time duration between first infection and reinfection was 63.6 ± 48.9 days. During first infection and reinfection, fever was the most common symptom (41.4% and 36.4%, respectively) whilst anti-viral therapy was the most common treatment regimen administered (44.5% and 43.0%, respectively). Comparable odds of symptomatic presentation and management were reported for the two infections. However, a higher Intensive Care Unit (ICU) admission rate was observed in reinfection compared to first infection (10 vs 3). Ten deaths were reported with respiratory failure being the most common cause of death (7/10 deaths).Conclusion: Our findings support immunization practices given increased ICU admissions and mortality in reinfections. Our cohort serves as a guide for clinicians and authorities in devising an optimal strategy for controlling the pandemic. (249 words)

Acceptance of COVID-19 vaccine in Pakistan: A nationwide cross-sectional study

Introduction: The coronavirus disease 2019 (COVID-19) vaccine is available across various countries worldwide, with public-private partnerships ensuring all individuals are vaccinated through a phased approach. Irrespective of the geographical spread, several myths pertaining to the COVID-19 vaccine have stemmed, ultimately limiting the national administration of vaccines and rollouts. This study assessed the acceptance of the COVID-19 vaccine among the general public in Pakistan.Methods: A pre-validated questionnaire was administered from January 2021 to February 2021 to assess the public attitude and acceptance of the COVID-19 vaccine. Logistic regression analyses were run to identify factors associated with the acceptance among the population.Results: A total of 936 responses were elicited, where 15% perceived their risk of being infected at 20-30% with an overall 70% agreeing to be vaccinated if recommended. Multivariate analysis identified higher acceptance in the male gender, healthcare workers, and students. Of all, 66% respondents chose healthcare workers and public officials, whereas 15.6% chose scientific literature, and 12.9% chose social media as the most reliable source of COVID-19 information.Conclusion: Given the relatively greater trust in healthcare providers for information regarding COVID-19, healthcare workers ought to be on the frontline for vaccine campaigns and public outreach efforts, with governmental efforts in addition to the promotion of scientific materials for population-level understanding

Prevalence of multi drug resistant organism in ICU burns patients at tertiary care hospital

Burns carries a high risk of mortality and morbidity. This with increased chances of drug-resistant infections makes the management complicated. Hence this study was conducted to find out the prevalence of multi-drug resistant organisms (MDRO) in burns patients admitted to the intensive care unit at a tertiary care hospital. A 2-year retrospective study was conducted where burn patients reporting MDRO were included. Statistical analysis was performed using SPSS version 26 where a p-value \u3c0.05 was considered statistically significant. Out of 97 patients, tissue cultures of 65 patients revealed the presence of MDRO in 27 (27.8%) patients. A male predominance (17, 63.0%) was noted with a mean age of 29.0-year-old. Fire burn (15, 55.6%) was reported to be the most common cause of burn with an average of 29.9% of Total Body Surface Area (TBSA) involved. MDR Pseudomonas aeruginosa was the commonest organism reported in 12 (44%) patients. The average length of stay (LOS) was noted to be 11.3 days with a mortality rate of 48.1% (Overall, in all MDRO\u27S infections). Patients who reported MDRO showed a tendency for longer hospitalization with a higher risk of mortality as the TBSA increased. However, in presence of other factors in burns like higher TBSA, inhalation injury and lack of advanced skin substitute these mortality figures, and their association can be debated. Lastly, the implementation of control measures, as basic as hand hygiene, should be partaken to reduce the burden of MDR infections

Who is at a higher risk? A brief review of recent evidence on comorbidities in children infected with COVID-19

COVID-19 has affected both adults and children with variable presentations and disease severity. Children can present with mild symptoms of fever, cough and shortness of breath, and rapidly progress to severe pneumonia, requiring mechanical ventilation. This population includes children who are younger than one year and older adolescents who have an underlying comorbidity-specifically immunosuppression or prior cardio-respiratory infections. In this review, we discuss the determinants of severe disease among the paediatric patients- primarily asthma, immune-status, obesity and multisystem inflammatory syndrome in children (MIS-C). Asthma and underlying lung pathologies can be a strong predictor (~20% prevalence) for development of severe COVID-19 infection, irrespective of age. However, as compared to asthma, a higher mortality rate was reported in immune-compromised patients. With a weakened immune system, immunosuppressed individuals were 1.55 times and immunocompromised patients 3.29 times more vulnerable to developing severer COVID-19 disease. Similarly, evidence suggests that a BMI of greater than 35 kg/m2 renders individuals more susceptible to developing COVID-19-related complications. This observation is based on the negative impacts obesity has on pulmonary functions and in downplaying the immune system. Furthermore, a possible association of COVID-19 and MIS-C has been reported by multiple studies across the globe but it needs further studies to strengthen its stance due to the scarcity of data when compared with the other determinants discussed in this article. Authors recommend researchers directing attention on synthesizing the evolving evidence to fill the knowledge void in the paediatric population, which will better enable paediatricians to make informed decisions

Health and Immune Boosting Techniques of General Adult Pakistani Population- A KAP Study

Objective: To discover Pakistani adult population’s perception about their general health, immune status and knowledge regarding immunity, and to highlight their efforts to improve it. Method: The knowledge-attitude-practice study was conducted from January to May 2021, after approval ethics review committee of the Islamic International Medical College, Rawalpindi, Pakistan, and comprised individuals of either gender from the community aged 18 years or more and not suffering from any physical disability or mental illness. Data was collected using a pre-tested, self-administered questionnaire that was disseminated through online platforms. The collected data was analysed using SPSS 25. Results: All the 455(100%) individuals approached responded to the questionnaire. The mean age of the subjects was the mean age was 22.6±7.579 years. There were 256(56.3%) female respondents, 283(62.2%) were aged 20-21 years, and 359(78.9%) hailed for the Sindh province. Most participants perceived their general health as ‘good’ 197(43.3%). The immune system function was reported ‘good’ by 200(44%), and the perception of general knowledge of immunity was reported ‘good’ by 189(41.5%) subjects. Inverse relationships were identified between stress levels and self-perceived health, and between receiving effective homeopathic treatment and ‘very good’ self-perceived immune status (p<0.05). People willing to take non-obligatory vaccines had a positive opinion about their self-perceived knowledge on immunity that produced a direct relationship (p<0.05). Conclusion: The findings provide a framework of practices that should be promoted to improve health status of adult population in Pakistan.

Residual symptoms and the quality of life in individuals recovered from COVID-19 infection: A survey from Pakistan

Background: There remains scarcity of literature regarding the patient\u27s health status post-COVID-19 infection. This study analyzes the prevalence of residual symptoms and quality of life (QoL) after COVID-19. Methods: An anonymous online survey was administrated in Pakistan from November 2020 to April 2021 in COVID-19 survivors. The questionnaire used the 12-Item Short Form Health Survey (SF-12) to assess mental and physical QoL. Multivariate linear regression was used to explore factors associated with mental and physical QoL scores. Results: A total of 331 COVID-19 survivors participated in our survey. Around 42.0% of the cohort reported within 1-3 months of diagnosis of COVID-19. The common residual symptoms were body aches (39.9%), low mood (32.6%), and cough (30.2%). Better physical QoL was associated with being male (adjusted beta: 3.328) and having no residual symptoms (6.955). However, suffering from nausea/vomiting during initial COVID-19 infection (-4.026), being admitted to the ICU during COVID-19 infection (-9.164), and suffering from residual body aches (-5.209) and low mood (-2.959) was associated with poorer QoL. Better mental QoL was associated with being asymptomatic during initial COVID-19 infection (6.149) and post-COVID (6.685), while experiencing low mood post-COVID was associated with poorer mental QoL (-8.253 [-10.914, -5.592]). Conclusion: Despite presumed recovery from COVID-19, patients still face a wide range of residual symptoms months after initial infection, which contributes towards poorer QoL. Healthcare professionals must remain alert to the long-lasting effects of COVID-19 infection and aim to address them appropriately to improve patients\u27 QoL

A global systematic review and meta-analysis on the emerging evidence on risk factors, clinical characteristics, and prognosis of multisystem inflammatory syndrome in adults (MIS-A)

Background: The multisystem inflammatory syndrome in adults (MIS-A) has emerged, similar to those in children associated with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) [multisystem inflammatory syndrome in children (MIS-C)]. This review aimed to analyze the risk factors, clinical course, and prognosis of MIS-A. Methods: A comprehensive literature search was conducted using several databases for cases reporting MIS-A from 1 December 2019 till 9 September 2021. The case definitions used to identify potential cases were those recommended by the World Health Organization, Center for Disease Control, and individual country/physician classification. The meta-analysis was performed using Comprehensive Meta-Analysis (CMA) 2.2.027 and Review Manager (RevMan) 5.4.1, employing 95% confidence intervals (CI). Results: Seventy studies were assessed for full-text eligibility, out of which 37 were included. The mean age of the study population was 32.52±10.29 years. The most common symptoms were fever (89.8%, 95% CI: 77.7-95.7%) and diarrhea (49%, 95% CI: 35.4-62.7%). Ventricular tachycardia (57.1%, 95% CI: 43.1-70.1%) was the most common electro-cardiac abnormality. The most common inflammatory marker was elevated C-reactive protein (89.8%, 95% CI: 77.7-95.7%). Abnormal echocardiogram was the most common imaging test result (commonly, ventricular dysfunction and arrhythmias), while steroids were the most administered treatment. Severe cases had a higher need for vasopressor and inotropic support and antibiotic therapy compared to the non-severe cases. One death was reported due to cardiovascular failure. Conclusion: Our collated findings will help clinicians identify the typical presenting symptoms and optimal management of MIS-A. Further research is required to understand the long-term prognosis and the correlation between coronavirus disease 2019 (COVID-19) and MIS-A to understand its pathogenesis and clinical spectru
