Background: The current pandemic of COVID-19 impacted the psychological wellbeing of populations globally. Objectives: We aimed to examine the extent and identify factors associated with psychological distress, fear of COVID-19 and coping. Methods: We conducted a cross-sectional study across 17 countries during Jun-2020 to Jan-2021. Levels of psychological distress (Kessler Psychological Distress Scale), fear of COVID-19 (Fear of COVID-19 Scale), and coping (Brief Resilient Coping Scale) were assessed. Results: A total of 8,559 people participated; mean age (±SD) was 33(±13) years, 64% were females and 40% self-identified as frontline workers. More than two-thirds (69%) experienced moderate-to-very high levels of psychological distress, which was 46% in Thailand and 91% in Egypt. A quarter (24%) had high levels of fear of COVID-19, which was as low as 9% in Libya and as high as 38% in Bangladesh. More than half (57%) exhibited medium to high resilient coping; the lowest prevalence (3%) was reported in Australia and the highest (72%) in Syria. Being female (AOR 1.31 [95% CIs 1.09-1.57]), perceived distress due to change of employment status (1.56 [1.29-1.90]), comorbidity with mental health conditions (3.02 [1.20-7.60]) were associated with higher levels of psychological distress and fear. Doctors had higher psychological distress (1.43 [1.04-1.97]), but low levels of fear of COVID-19 (0.55 [0.41-0.76]); nurses had medium to high resilient coping (1.30 [1.03-1.65]). Conclusions: The extent of psychological distress, fear of COVID-19 and coping varied by country; however, we identified few higher risk groups who were more vulnerable than others. There is an urgent need to prioritise health and well-being of those people through well-designed intervention that may need to be tailored to meet country specific requirements.

COVID-19 is a severe respiratory disease caused by the newly identified human coronavirus (HCoV) Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The virus was discovered in December 2019, and in March 2020, the disease was declared a global pandemic by the World Health Organization (WHO) due to a high number of cases. Although SARS-CoV-2 primarily affects the respiratory system, several studies have reported neurological complications in COVID-19 patients. Headache, dizziness, loss of taste and smell, encephalitis, encephalopathy, and cerebrovascular diseases are the most common neurological complications that are associated with COVID-19. In addition, seizures, neuromuscular junctions’ disorders, and Guillain–Barré syndrome were reported as complications of COVID-19, as well as neurodegenerative and demyelinating disorders. However, the management of these conditions remains a challenge. In this review, we discuss the prevalence, pathogenesis, and mechanisms of these neurological sequelae that are secondary to SARS-CoV-2 infection. We aim to update neurologists and healthcare workers on the possible neurological complications associated with COVID-19 and the management of these disease conditions.

Purpose: To establish the first comprehensive and standardized set of vagus nerve (VN) sonographic reference values across all the published studies that can be used to standardize and guide clinical practice and research. Methods: This systematic review includes all possible available data from a total of 27 studies and 21 of them were included in the meta-analysis having a total of 864 participants. Results: The overall mean cross-sectional area ranged from 2.29 to 2.76 mm² for the right VN and from 1.83 to 2.23 mm² for the left VN with 95% confidence interval. Sonographic reference values of VN at common carotid artery bifurcation, thyroid gland, and cartilage as well as other anatomic landmarks were provided. Conclusions: The mean cross-sectional area of the right VN of 2.53 mm² and the left one of 2.03 mm² can be considered as sonographic reference values in healthy adults. This review provides these reference values to be considered in the further sonographic evaluation of VNs.

Inclusion body myositis (IBM) is a slowly progressive muscle weakness of distal and proximal muscles, which is diagnosed by clinical and histopathological criteria. Imaging biomarkers are inconsistently used and do not follow international standardized criteria. We conducted a systematic review and meta-analysis to investigate the diagnostic value of muscle ultrasound (US) in IBM compared to healthy controls. A systematic search of PubMed/MEDLINE, Scopus and Web of Science was performed. Articles reporting the use of muscle ultrasound in IBM, and published in peer-reviewed journals until 11 September 2021, were included in our study. Seven studies were included, with a total of 108 IBM and 171 healthy controls. Echogenicity between IBM and healthy controls, which was assessed by three studies, demonstrated a significant mean difference in the flexor digitorum profundus (FDP) muscle, which had a grey scale value (GSV) of 36.55 (95% CI, 28.65–44.45, p < 0.001), and in the gastrocnemius (GC), which had a GSV of 27.90 (95% CI 16.32–39.48, p < 0.001). Muscle thickness in the FDP showed no significant difference between the groups. The pooled sensitivity and specificity of US in the differentiation between IBM and the controls were 82% and 98%, respectively, and the area under the curve was 0.612. IBM is a rare disease, which is reflected in the low numbers of patients included in each of the studies and thus there was high heterogeneity in the results. Nevertheless, the selected studies conclusively demonstrated significant differences in echogenicity of the FDP and GC in IBM, compared to controls. Further high-quality studies, using standardized operating procedures, are needed to implement muscle ultrasound in the diagnostic criteria.

Background: The definition of minor ischemic stroke (MIS) is a topic of debate, however, the most accepted definition is a stroke with National Institutes of Health Stroke Scale (NIHSS) ≤ 5. Intravenous thrombolysis (IVT) is a crucial treatment option for acute ischemic stroke (AIS) including: alteplase, recombinant human tissue-type plasminogen activator (r-tPA), and the recently approved tenecteplase. However, there is a debate regarding its safety and efficacy. Therefore, our objective was to determine the safety and efficacy of IVT in treating minor stroke patients (NIHSS ≤ 5). Methods: Using the search strategy assigned which was based on three keywords: “mild” or “minor”, “stroke”, and “intravenous thrombolysis”, we searched for eligible articles on PubMed, Web of Science, Embase, and Scopus from inception till 10th January 2024. We conducted this meta-analysis using the random effect model to account for the heterogeneity among the studies. For the dichotomous variables, we calculated the odds ratio (OR) from the event and total of these variables. While for the continuous variables, we calculated the mean difference (MD) of these variables. Pooling of OR for the occurrence of events was also conducted. Results: A total of 21 articles with 93,057 patients with MIS were included. The mean age of the participants ranged from 62.3 to 79.6. Most of the included patients had comorbidities such as hypertension, diabetes, previous stroke, smoking, atrial fibrillation, and hyperlipidemia. Of these, 10,850 received IVT while 82,207 did not. The use of IVT was statistically significant associated with 90-day modified Rankin score (mRs) 0–1 when compared with control with OR of 1.67 (95%CI: 1.46, 1.91, p < 0.00001) and was statistically significantly associated with improvement of NIHSS on discharge with OR of 2.19 (95%CI: 1.56, 3.08, p < 0.00001). In terms of safety outcomes, IVT has proven a safe profile, as there was no significant difference in intracranial hemorrhage (ICH) and mortality rates between the IVT and control groups with OR of 1.75 (95CI: 0.95, 3.23, p = 0.07) and 0.93 (95%CI: 0.77, 1.11, p = 0.41), respectively. Conclusion: Although some studies have not found any benefits of IVT in MIS patients, a substantial body of literature strongly endorses IVT as an effective and safe treatment for MIS. IVT has been shown to improve the mRs and NIHSS scores at the 90-day mark without an increased risk of ICH or mortality.
