ABSTRACT
Introduction: The COVID-19 pandemic had a significant impact on the mental health of health care workers (HCWs). Aim: This study investigated the mental health of HCWs working in Leicester, UK during COVID-19. Settings: Two hospital trusts in Leicester, UK. Methods: An online survey was sent to HCWs in two trusts in July 2020. The Generalized Anxiety Disorder-7 scale (GAD-7) and the Patient Health Questionnaire-9 scale (PHQ-9) were used to measure the prevalence rates of anxiety and depression. The Perceived Stress Scale-14 (PSS-14) was used to measure levels of perceived stress. Other questions were used to identify the prevalence of increased alcohol intake and possible risk factors. Statistical Analysis Used: Chi-square test, independent sample t-test, ANOVA, and logistic regression. Results: A total of 1009 HCWs completed the survey. Using a cutoff score of 5 (mild symptoms), for both GAD-7 and PHQ-9, 80.2% of participants had at least one condition and 71.5% had both. Using the cutoff score of 10 (moderate/severe symptoms), 27.2% had at least one condition and 27.25% had both conditions. In addition, 37.5% of those who did not report pre-existing mental health conditions now have at least one condition. About 33.6% of participants reported an increase in alcohol consumption. A number of risk factors were identified: having less social support, not feeling supported at work, and poor pre-existing mental health. Conclusions: The pandemic had a significant impact on mental health of HCWs. Health organizations need to monitor and address these emerging effects.
ABSTRACT
BACKGROUND: We diagnosed various cases of rhino-orbital-cerebral- COVID-associated Mucormycosis (ROCM-CAM) during India's second wave of COVID-19. This helped formulate novel suggestions for improving laboratory output, applicable anywhere in the world. METHOD: To diagnose ROCM-CAM by microbiological methods, we used direct microscopy and conventional culture on various clinical samples within the shortest turn-around time. DESIGN: Prospective single-center observational study Participants: patients with ROCM-CAM Results: Of 113 suspected cases of ROCM-CAM during May 2021, direct microscopy and culture could confirm the disease in 87.61% and 44.25% of patients, respectively. The highest pathogen isolation was seen from maxillary bone fragments, FESS-guided biopsy from pterygopalatine fossae, nasal turbinates and nasal mucosal biopsy. Direct microscopy could diagnose the disease in almost 40% of patients within 24 hours and 60% within two days. Conventional cultures yielded Rhizopus spp. (86%) as the commonest fungal pathogen followed by Mucor spp. (12%) within 7 days. Deep tissue biopsies are more useful for rapid diagnosis than superficial specimens. Routine fungal cultures can supplement case detection and help prognosticate survivors. CONCLUSION: The management of ROCM is a surgical emergency. The diagnosis of the condition must therefore be prompt and precise. Despite ongoing antifungal therapy, nasal mucosal tissue, FESSguided, and intra-operative tissue biopsies showed the pathogen's highest diagnostic yield. The diagnostic index improved further when multiple (4-5) high-quality specimens were collected. Nasal swabs and crusts, among the most commonly requested specimens worldwide, were found to have an overall low diagnostic potential.
ABSTRACT
The ongoing COVID-19 pandemic highlights the need to tackle viral variants, expand the number of antigens, and assess diverse delivery systems for vaccines against emerging viruses. In the present study, a DNA vaccine candidate was generated by combining in tandem envelope protein domain III (EDIII) of dengue virus serotypes 1-4 and a dengue virus (DENV)-2 non-structural protein 1 (NS1) protein-coding region. Each domain was designed as a serotype-specific consensus coding sequence derived from different genotypes based on the whole genome sequencing of clinical isolates in India and complemented with data from Africa. This sequence was further optimized for protein expression. In silico structural analysis of the EDIII consensus sequence revealed that epitopes are structurally conserved and immunogenic. The vaccination of mice with this construct induced pan-serotype neutralizing antibodies and antigen-specific T cell responses. Assaying intracellular interferon (IFN)-γ staining, immunoglobulin IgG2(a/c)/IgG1 ratios, and immune gene profiling suggests a strong Th1-dominant immune response. Finally, the passive transfer of immune sera protected AG129 mice challenged with a virulent, non-mouse-adapted DENV-2 strain. Our findings collectively suggest an alternative strategy for dengue vaccine design by offering a novel vaccine candidate with a possible broad-spectrum protection and a successful clinical translation either as a stand alone or in a mix and match strategy.
