Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
The current pandemic of coronavirus disease 2019 (COVID-19) that led to an unprecedented crisis with significant health, social, and economic repercussions presented more serious concerns for those living with some chronic conditions such as epilepsy. This study was aimed to find out impact of the COVID-19 pandemic on management of epilepsy. A cross-sectional study was conducted through telephone interviews, targeting 213 caregivers of pediatric patients with epilepsy, belonging to underserved areas of Faisalabad, Punjab, Pakistan. A simple questionnaire was designed to record the responses of participants relevant to the direct and indirect effects of COVID-19 pandemic and their knowledge about possible ways that can be accessed for the management of epilepsy during an ongoing pandemic. The current study, which holds 77% of the respondents from rural areas and 23% from urban settings, showed that partial measures of lockdown taken to stop or slow the spread of COVID-19 resulted in adverse economic and health outcomes in the said population including cancelation of follow-up visits, worsening of seizures, job loss, burden of antiepileptic drugs (AEDs) costs, and discontinuation of medicines. Furthermore, knowledge about alternative ways to access health facilities was found very poor among caregivers. Income sources of poor people disrupted by lockdown can lead to unintentional nonadherence to medication, which is a clear picture of inequitable distribution of resources. This study highlights the major issues faced by the caregivers during this ongoing pandemic of COVID-19.
Objective: The objective of this study is to assess the stress levels of Pakistani dental students through an established stress assessment tool during lockdown for COVID-19 pandemic. Materials and methods: A cross-sectional quantitative study using a self-administered, voluntarily filled online questionnaire was conducted on undergraduate dental students from first to fourth (Final) years of dental institutes across Pakistan, accredited by the Pakistan Medical & Dental Council (PMDC). Study questionnaire contained questions on demographic details; gender, province of college, province of residence and perceived stress scale of 10 questions. It also contained questions about the presence of any symptoms relevant to a particular type of stress. i.e. emotional stress, physical (body related) stress, behavioral stress and cognitive stress. Descriptive statistics were calculated for gender, residence of participants, location of institutes, levels of stress and symptoms signifying a particular stress type. Multiple variables of each stress type were compared with categories of perceived stress scores using chi square test. Results: 706 dental students responded. 53.5% were going through high stress levels, 43.4% were going through moderate stress levels while 2.9% were having low stress levels. Majority of the participants with moderate and high stress levels were from institutions located in provinces with increased number of COVID-19 positive cases. Among moderate and highly stressed participants, more than 68% were females. A significant number of dental students reported symptoms pertaining to emotional, physical, cognitive and behavioral stress due to the COVID-19 disease. Conclusion: Majority of Pakistani dental students are suffering from moderate to high stress levels specially in provinces with a higher number of COVID-19 affected reported cases. There are considerable effects on emotional, physical, cognitive and behavioral states of Pakistani dental students due to the spread of this disease.
