The coronavirus disease 2019 (COVID-19) pandemic has caused enormous psychological impact worldwide. We conducted a systematic review and meta-analysis on the psychological and mental impact of COVID-19 among healthcare workers, the general population, and patients with higher COVID-19 risk published between 1 Nov 2019 to 25 May 2020. We conducted literature research using Embase, PubMed, Google scholar and WHO COVID-19 databases. Among the initial search of 9207 studies, 62 studies with 162,639 participants from 17 countries were included in the review. The pooled prevalence of anxiety and depression was 33% (95% confidence interval: 28%-38%) and 28% (23%-32%), respectively. The prevalence of anxiety and depression was the highest among patients with pre-existing conditions and COVID-19 infection (56% [39%-73%] and 55% [48%-62%]), and it was similar between healthcare workers and the general public. Studies from China, Italy, Turkey, Spain and Iran reported higher-than-pooled prevalence among healthcare workers and the general public. Common risk factors included being women, being nurses, having lower socioeconomic status, having high risks of contracting COVID-19, and social isolation. Protective factors included having sufficient medical resources, up-to-date and accurate information, and taking precautionary measures. In conclusion, psychological interventions targeting high-risk populations with heavy psychological distress are in urgent need.

The psychological and mental impact of coronavirus disease 2019 (COVID-19) on medical staff and general public - A systematic review and meta-analysis.

Objective We conducted a systematic review and meta-analysis to estimate the pooled prevalence of depression, anxiety, insomnia, PTSD, and Psychological distress (PD) related to COVID-19 among affected populations. Methods We searched articles in Medline, Embase, APA PsycInfo, CINAHL, Scopus, and Web of Science. Random-effects meta-analyses on the proportions of individuals with symptoms of depression, anxiety, insomnia, PTSD, and PD were generated and between-group differences for gender, healthcare workers (HCWs), and regions where studies were conducted. Results A total of 2189 articles were screened, 136 full-text articles were assessed for eligibility. Fifty-five peer-reviewed studies met inclusion criteria for the meta-analysis (N=189,159). The prevalence of depression (k=46) was 15.97% (95%CI, 13.24-19.13). The prevalence of anxiety (k=54) was 15.15% (95%CI, 12.29-18.54). The prevalence of insomnia (k=14) was 23.87% (95%CI, 15.74-34.48). The prevalence of PTSD (k=13) was 21.94% (95%CI, 9.37-43.31). Finally, the prevalence of psychological distress (k=19) was 13.29% (95%CI, 8.80-19.57). Between-group differences were only found in HCWs (z=2.69, p Conclusions Findings suggest that the short-term mental health consequences of COVID-19 are equally high across affected countries, and across gender. However, reports of insomnia are significantly higher among HCWs than the general population.

The consequences of refractory epilepsy and its treatment

Objective The definition of drug-resistant epilepsy (DRE) affects case identification and treatment, and impacts prevalence or incidence estimates and health burden estimation in epidemiology. The objective of this systematic review is to evaluate the consistency between definitions of DRE in the literature and the official definition in the International League Against Epilepsy (ILAE) guidelines, and to estimate the incidence, prevalence, and risk factors for DRE. Methods MEDLINE and EMBASE were searched for observational studies of DRE published between January 1980 and July 2015. The definitions of DRE in these studies were compared with the definition in the ILAE guidelines. Random-effect model meta-analyses were used to generate pooled estimates of prevalence or incidence and pooled odds ratios of the association with risk factors. Results Thirty-five studies met inclusion criteria, including 13 080 epilepsy patients and 3941 patients with DRE. The definition of DRE varied widely across studies, with only 12% meeting the requirements of the ILAE definition. The pooled prevalence proportion of DRE among epilepsy patients was 0.30 (95% confidence interval [CI] 0.19-0.42), and the pooled incidence proportion was 0.15 (95% CI 0.11-0.19). Age at onset, symptomatic epilepsy, abnormal neuroimaging findings, abnormal electroencephalography results, history of mental retardation, neuropsychiatric disorders, febrile seizure, and status epilepticus increased risk for DRE. Significance There are limited high-quality data available on DRE. Lack of consistency in definitions limits the ability to obtain robust estimates on the burden of DRE. More data based on the ILAE definition from well-designed epidemiologic studies are needed to generate accurate and reliable results.

The epidemiology of drug-resistant epilepsy: A systematic review and meta-analysis.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) outbreak has escalated the burden of psychological distress. We aimed to evaluate factors associated with psychological distress among the predominantly general population during the COVID-19 pandemic. METHODS: We searched PubMed, EMBASE, Scopus, Cochrane Library, PsycINFO, and World Health Organization COVID-19 databases (Dec 2019-15 July 2020). We included cross-sectional studies that reported factors associated with psychological distress during the COVID-19 pandemic. Primary outcomes were self-reported symptoms of anxiety and depression. Random-effects models were used to pool odds ratios (OR) and 95% confidence intervals (CI). The protocol was registered in PROSPERO (#CRD42020186735). FINDINGS: We included 68 studies comprising 288,830 participants from 19 countries. The prevalence of anxiety and depression was 33% (95% CI: 28%-39%) and 30% (26%-36%). Women versus men (OR: 1.48 [95% CI: 1.29-1.71; I2 = 90.8%]), younger versus older (< versus ≥35 years) adults (1.20 [1.13-1.26]; I2 = 91.7%), living in rural versus urban areas (1.13 [1.00-1.29]; I2 = 82.9%), lower versus higher socioeconomic status (e.g. lower versus higher income: 1.45 [1.24-1.69; I2 = 82.3%]) were associated with higher anxiety odds. These factors (except for residential area) were also associated with higher depression odds. Furthermore, higher COVID-19 infection risk (suspected/confirmed cases, living in hard-hit areas, having pre-existing physical or mental conditions) and longer media exposure were associated with higher odds of anxiety and depression. INTERPRETATION: One in three adults in the predominantly general population have COVID-19 related psychological distress. Concerted efforts are urgently needed for interventions in high-risk populations to reduce urban-rural, socioeconomic and gender disparities in COVID-19 related psychological distress.

Factors associated with psychological distress during the coronavirus disease 2019 (COVID-19) pandemic on the predominantly general population: A systematic review and meta-analysis.

It has been suggested that uncontrolled epilepsy might not necessarily equate to drug resistance when antiepileptic drugs (AEDs) are used at relatively low doses, a practice frequently observed in rural areas of China. To assess the clinical benefits of further drug manipulation in this situation, we prospectively followed up the outcomes of patients with uncontrolled epilepsy while taking relatively low doses of AEDs. The study included patients aged 16 years and older with uncontrolled epilepsy and who were receiving at least one AED at a dosage below 50% of the World Health Organization (WHO) defined daily dose (DDD) (50% DDD) (Group 1). Patients with drug-resistant epilepsy were included for comparison (Group 2). Both groups were followed-up for at least 2 years. Seizure outcomes after further drug manipulations were recorded at the last follow-up. A total of 197 patients (55.3% male) were included in Group 1 and 32 (46.9% male) in Group 2; their mean duration of follow-up was 28.85 ± 1.90 and 30.91 ± 2.04 months, respectively. At the last follow-up, 16.8% (33/197) of patients in Group 1 had become seizure-free compared with none in Group 2 (p < 0.001). Seventeen of 93 (18.3%) patients in Group 1 became seizure free after increasing the dosage of baseline AED(s) alone. Only 5.5% (3/55) of patients who had failed to respond to an AED at ≥50% DDD at baseline became seizure free compared with 21.1% (30/142) who did not have such a history (p = 0.001). The number of AEDs taken at a dosage below 50% DDD at baseline was not associated with seizure outcome. Uncontrolled epilepsy could become controlled in a substantial proportion of patients by dose increase alone, particularly if there is no history of drug failure at ≥50% DDD.

Anti-Caspr2 encephalitis coexisting with neurosyphilis: a rare case report.

Objectives To extend the symptomatic spectrum of acute neurologic syndrome associated with dopamine-2 receptor (D2R) antibodies. Methods A 13-year-old adolescent boy was admitted to the Neurology Department with abnormal jaw movements. The initial evaluation included laboratory examinations of blood, chest radiography, brain MRI, EEG, and neuropsychologic tests. Serum and CSF samples were collected for immunologic studies. The clinical outcome of the patient was followed up for 18 months after the first hospitalization. Results Paroxysmal jaw clonus, blepharospasm, and sialorrhea were observed in the patient with a history of Tourette syndrome and obsessive–compulsive disease and with an acute neurologic syndrome associated with D2R antibodies. The symptoms responded to IV methylprednisolone (IVMP), relapsed twice during prednisone reduction, and, finally, improved after the combined treatment of IVMP and IV immunoglobulin. Discussion Recognizing paroxysmal jaw clonus (possibly with blepharospasm and sialorrhea) and considering the relationship between these episodes and D2R antibodies will be helpful in the early diagnosis and treatment of immune neurologic syndromes.

Relapsing and Immune-Responsive Paroxysmal Jaw Clonus With Blepharospasm and Sialorrhea Associated With D2R Autoantibodies

Background: The high prevalence of nonsuicidal self-injury (NSSI) in youths demonstrates a substantial population-level burden on society. NSSI is often associated with emotional and social skill deficits. To date, several studies have aimed to identify the underlying neural mechanism of those deficits in NSSI by using functional magnetic resonance imaging (fMRI). However, their conclusions display poor consistency. Objective: We aimed to conduct a meta-analysis using activation likelihood estimation (ALE) for fMRI data based on emotional and cognitive tasks to clarify the underlying neural processing deficits of NSSI. Methods: We searched for MRI studies of NSSI in the PubMed, Cochrane, and Embase databases. We identified significant foci for the included studies and conducted two ALE meta-analyses as follows: (i) activation for the NSSI contrast healthy control group and (ii) deactivation for the NSSI contrast healthy controls. Considering the diverse sex composition of study participants and possible bias from one large sample study, we conducted sensitivity analyses for the meta-analysis. Results: Nine studies comprising 359 participants were included, and the results demonstrated substantial activation in NSSI patients compared with healthy controls in two clusters located in the right medial frontal gyrus extending to the rostral anterior cingulate and the left inferior frontal gyrus extending to the insula. Conclusions: The results suggest that individuals with NSSI show brain activity alterations that underpin their core symptoms, including poor emotional regulation and reward processing deficits. Our findings provide new insights into the neural mechanism of NSSI, which may serve as functional biomarkers for developing effective diagnosis and therapeutic interventions for these patients.
