ABSTRACT
Neurological symptomatology is a crucial component of neurological expertise. The committee for fostering board-certified neurologists in the Japanese Society of Neurology (JSN) has hosted an educational activity for residents before the board examination, "The seminar for fostering board-certified neurologists" since 2004. In particular, the autumn seminar has been characterized by small group hands-on of neurological examinations and the evaluations of higher brain function. Besides this, hands-on seminar of neurological examinations by regional branches has been promoted by the JSN. In the Kanto Ko-shin-etsu branch, "The first hands-on seminar of neurological examinations" started in 2023 after a 3-year-suspension due to COVID-19. The most important educational activities in neuromuscular electrodiagnosis (EDx) is the "Neuromuscular diagnostics seminar" hosted since 2004 by the Japanese Society of Clinical Neurophysiology (JSCN). The majority of tutors and participants are neurologists. This seminar is also characterized by small-group, hands-on workshops. We have also run the overseas seminar, "Tokyo Super EMG hands-on," since 2013. These have undoubtedly contributed to enhancing the level of neuromuscular electrodiagnosis not only in Japan but also in other Asian countries. I have conducted studies on neurological symptomatology and neuromuscular electrodiagnosis, which are directly linked to enhancing clinical practice of neurologists through educational activities such as review articles or lectures. Due to the fact that symptomatology is crucial in neurological expertise, neurology is a basic specialty around the world except in Japan. In 2018, the JSN decided to aim to make neurology a basic specialty and continues to make efforts to attain this goal.Copyright © 2023 Japanese Society of Neurology and John Wiley & Sons Australia, Ltd.
ABSTRACT
Cognitive dysfunction is one of the manifestations of the neurological complications in coronavirus infection. In this article, we have collected material on the state of cognitive functions after suffering a coronavirus infection with aspects of possible pathogenetic mechanisms and a discussion on the prospects for treatment and rehabilitation. The COVID-19 pandemic, having manifested itself in December 2019, remains one of the most controversial topics in the world to the day. The growing number of reports about damage to the nervous system during coronavirus infection suggests that the virus is neurotropic. In the clinical picture of the disease, less attention is paid to such symptoms as severe weakness, fatigue, memory impairment. At the same time, it is this symptomatology that most often accompanies patients in the postcovid period and significantly reduces their quality of life, thereby making it difficult to adapt to social and work activities. The search was conducted for literatures published within the period from 2020 to the third quarter of 2021, domestic and foreign sources from the Web of Science, PubMed databases were analysed. The search queries were the following ones: "COVID-19", "cognitive impairment", "postcovid syndrome".Copyright © 2022, Krasnoyarsk State Medical University. All rights reserved.
ABSTRACT
In 2019, a new coronavirus (COVID-19) was discovered in Wuhan, China, which soon spread all over the world. The main hallmark of the disease includes fever, diarrhea, vomiting, and dry cough with dyspnea in half of the patients and acute respiratory distress syndrome (ARDS). Currently, no definitive treatment or prevention therapy exists for COVID-19 but scientists and researchers all over the world are relentlessly working to understand COVID-19 to discover novel therapeutic tools and vaccines. Today, photodynamic therapy (PDT) has been investigated as a noninvasive therapy for the treatment of this pandemic and was able to increase the healing process with the help of appropriate photosensitizers by targeting the pathogen inside the patient's body.
ABSTRACT
PurposeThis research aims to analyse the variables related to the purchase intention of COVID-19 rapid tests in Monterrey, Mexico's metropolitan area.Design/methodology/approach The chosen method was probit regression. The results show that purchase intention depends on the consumer's perceived value and the perception of having a potential contagion and/or presenting symptoms related to the virus. Regarding limitations, the sampling method used in this investigation is a nonprobabilistic convenience approach delivered through a digital platform, which may not be the first option in other contexts.FindingsThe findings indicate that the probability of the purchase intention of rapid COVID tests increases when consumers perceive symptoms of the disease and when they have higher education or are female rather than concerning price or income, as suggested by classical demand theory.Research limitations/implicationsProbabilistic sampling was impossible due to the difficulty of collecting surveys during the COVID-19 pandemic. Instead, a nonprobabilistic sample of a representative random selection of different zip codes from the responses received was considered.Originality/valueThe originality of the paper is its contribution to consumer behaviour during the COVID-19 pandemic in a Latin American context.
ABSTRACT
OBJECTIVE: To determine levels of postpartum depression symptoms and possible relevant predictors, such as death anxiety, health anxiety, and coronavirus-related anxiety. DESIGN: Cross-sectional web-based survey using quantitative methods. SETTING: Exclusively online recruiting via social media and unpaid cross-posting conducted during the third wave of the COVID-19 pandemic in Romania. PARTICIPANTS: Women were eligible to take part in the study if they were mothers over the age of 18 and had a baby aged between 4 weeks - 12 months of age; 1024 women were included in the final sample. MEASUREMENTS AND FINDINGS: Health anxiety, death anxiety, coronavirus-related anxiety, and postpartum depression symptoms were measured using validated instruments. Current depression symptomatology was 67.6%, 26.7% scored above the cut-off for high health anxiety, 1% for coronavirus-related anxiety, and 62.7% for death anxiety. Significant predictors for depressive symptomatology were breastfeeding, history of depression, family income, number of children, health anxiety, death anxiety, and coronavirus anxiety. Further, hierarchical multiple regression analysis indicated that death anxiety, health anxiety, and coronavirus anxiety predicted postpartum depression symptoms over and above socio-demographic factors. KEY CONCLUSIONS: Supported by previous studies, our results suggest that postpartum depression symptomatology levels during the COVID-19 pandemic are high and that they are predicted by health and death anxiety, which are also increased during the pandemic. IMPLICATION FOR PRACTICE: The findings provide information to identify the risk for depression symptoms in postpartum mothers during acute public health situations.
ABSTRACT
It seems that things are calming down with SARS-Cov-2, as there are no longer daily reports and notes of findings of new variants and subvariants of the virus, as well as clinical changes in symptomatology, hospitalizations, severity, and deaths due to COVID-19. We do not know how we should guard against viral infection during the impending endemic phase of the disease, knowing the complex health problems of prolonged COVID if we contract the virus. In this article we describe the latest known coronavirus mutations, how they affect certain organs and systems, the advantage of a better response to infection in people with healthy lifestyle, the rebound of symptomatology, reinfections at the time of the vaccine, prolonged COVID, excess mortality of physicians who attended the first waves without vaccine, and some news and knowledge about COVID in the pregnant woman and her fetus and newborn;the future of the newborn born to a mother with COVID remains unknown. In the COVID endemic, should we continue to protect ourselves? How?Copyright © Peruvian Society of Obstetrics and Gynecology. All Rights Reserved.
ABSTRACT
The problem of the incidence of new coronavirus infection in childhood is becoming increasingly important. At the same time, questions arise regarding the peculiarities of the pathogenesis of COVID-19 in children. The aim of the research was to study the clinical and immunological features of COVID-19 in children hospitalized with a severe course of the disease. Material and methods. We examined 53 children from 0 to 15 years old, hospitalized with suspected new coronavirus infection at Children's Clinical Hospital No. 3 in Novosibirsk from October to December 2020. Determination of specific IgM and IgG antibodies to SARS-CoV-2 antigens in serum blood was carried out using the ELISA method. SARS-CoV-2 virus RNA in nasopharyngeal and oropharyngeal swabs was determined using commercial kits for PCR diagnostics. A z-test was used to compare relative numbers. The significance level was taken equal to 5% (p=0.05). Results and discussion. All examined children hospitalized with suspected COVID-19, regardless of the duration of the disease, had specific IgG antibodies to SARS-CoV-2 antigens, which confirms earlier contact with the new coronavirus in relation to the time of the examination. In 63.6% of cases, specific IgM antibodies of the class to SARS-CoV-2 were detected in the blood serum, in 6% of cases the result was doubtful. IgM antibodies were not detected in blood serum in 30.3% of patients. The results obtained for the determination of IgG and IgM antibodies to SARS-CoV-2 antigens may reflect the atypical nature of seroconversion in COVID-19. An extremely diverse clinical symptomatology was revealed, including, in addition to catarrhal syndrome and intoxication syndrome, abdominal, meningeal, and articular syndromes. In 24.3% of children, polymorphic exanthema was detected, which may be a manifestation of the systemic nature of damage to the vascular wall. Conclusion. With serologically confirmed SARS-CoV-2 etiology of the infectious process in the examined children, an extremely diverse clinical symptomatology was revealed, which, most likely, may be associated with multiple organ damage.Copyright © Transplantologiya.

ABSTRACT
Objective: To analyze the characteristics of traditional Chinese medicine (TCM) syndromes of patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) omicron variant in a shelter hospital in Shanghai. Methods: A total of 621 patients infected with SARS-CoV-2 omicron variant from Apr. 4 to May 24, 2022 in a shelter hospital in Shanghai were enrolled. The data of the patients, including the general information and common clinical syndromes (such as fever, headache, stuffy nose, runny nose, cough, and sputum), were collected on admission by TCM syndrome electronic scale, and core syndrome characteristics were analyzed base on the proportion of each symptom. The syndromes were divided according to the symptom score of patients, and the differences of disease course among the syndromes were compared. Results: The proportion of patients aged 30 to 49 years old was the highest among 621 patients infected with omicron variant (49.76%, 309/621). The most prominent symptoms were cough and expectoration, accounting for 62.32% (387/621) and 68.12% (423/621), respectively. The more common symptoms included sore throat, stuffy nose, runny nose, fatigue, muscle pain, and headache. White sputum was mostly seen in the expectoration and clear mucus was mostly seen in runny nose. According to the clinical symptoms, the core syndrome characteristic of patients infected with omicron variant was cold epidemic constraint in the lung featuring dampness and toxins. The main syndrome was plague invading the defensive exterior, accounting for 40.10% (249/621). The second and third ones were heat toxin attacking the lung syndrome (29.95%, 186/621) and dampness obstructing (17.55%, 109/621), while the least common syndrome was deficiency of qi and yin (7.73%, 48/621). The course of qi and yin deficiency was longer than the other 3 syndromes (P < 0.05). Conclusion: The core TCM syndrome characteristic of patients infected with SARS-CoV-2 omicron variant is cold epidemic constraint in the lung featuring dampness and toxins. The main syndrome is plague invading the defensive exterior. The pattern tends to convert into qi and yin deficiency along the long course.
ABSTRACT
The novel coronavirus SARS-CoV-2, which emerged in late 2019, has since spread around the world and infected hundreds of millions of people with coronavirus disease 2019 (COVID-19). While this viral species was unknown prior to January 2020, its similarity to other coronaviruses that infect humans has allowed for rapid insight into the mechanisms that it uses to infect human hosts, as well as the ways in which the human immune system can respond. Here, we contextualize SARS-CoV-2 among other coronaviruses and identify what is known and what can be inferred about its behavior once inside a human host. Because the genomic content of coronaviruses, which specifies the virus's structure, is highly conserved, early genomic analysis provided a significant head start in predicting viral pathogenesis and in understanding potential differences among variants. The pathogenesis of the virus offers insights into symptomatology, transmission, and individual susceptibility. Additionally, prior research into interactions between the human immune system and coronaviruses has identified how these viruses can evade the immune system's protective mechanisms. We also explore systems-level research into the regulatory and proteomic effects of SARS-CoV-2 infection and the immune response. Understanding the structure and behavior of the virus serves to contextualize the many facets of the COVID-19 pandemic and can influence efforts to control the virus and treat the disease. IMPORTANCE COVID-19 involves a number of organ systems and can present with a wide range of symptoms. From how the virus infects cells to how it spreads between people, the available research suggests that these patterns are very similar to those seen in the closely related viruses SARS-CoV-1 and possibly Middle East respiratory syndrome-related CoV (MERS-CoV). Understanding the pathogenesis of the SARS-CoV-2 virus also contextualizes how the different biological systems affected by COVID-19 connect. Exploring the structure, phylogeny, and pathogenesis of the virus therefore helps to guide interpretation of the broader impacts of the virus on the human body and on human populations. For this reason, an in-depth exploration of viral mechanisms is critical to a robust understanding of SARS-CoV-2 and, potentially, future emergent human CoVs (HCoVs).Copyright © 2021 Rando et al.
ABSTRACT
Background: At least 10% of SARS-CoV-2 infected patients suffer from persistent symptoms for >12 weeks, known as post-COVID-19 condition (PCC) or Long Covid. Reported symptomatology is diverse with >200 physical and neurological debilitating symptoms. Here, we analyzed pro-inflammatory cytokine levels as a potential mechanism underlying persistent symptomatology. Method(s): Clinical data and samples used belong to the KING cohort extension, which includes clinically well characterized PCC (N=358, 59 persistent symptoms evaluated), COVID-19 recovered and uninfected subjects. We used Gower distances to calculate symptom's similarity between PCC and Ward's hierarchical clustering method to identify different symptom patterns among PCC patients. Cytokine levels of randomly selected PCC, recovered and uninfected subjects (N=193) were measured on plasma samples collected >6 months after acute infection using the 30-Plex Panel for Luminex. Mann- Whitney t-test was used to compare PCC vs recovered groups and Kruskal-Wallis t-test for >2 groups comparisons (PCC vs recovered vs Uninfected and within PCC clusters). FDR correction was applied for statistical significance (p-adj). Result(s): Hierarchical clustering identified 5 different PCC clusters according to their symptomatology, where PCC3 and PCC5 clusters showed higher prevalence of women ( >80%) and more persistent symptoms, while acute COVID-19 was mild in >80% of the patients. We selected 91 PCC (belonging to each cluster), 57 recovered and 45 uninfected subjects for cytokine profiling (Table 1). 13 soluble markers were significantly elevated (IL-1beta, Eotaxin, MIP-1beta, MCP-1, IL-15, IL-5, HGF, IFN-alpha, IL-1RA, IL-7, MIG, IL-4 and IL-8) in PCC and recovered groups compared to uninfected subjects (all p-adj< 0.04). In addition, PCC subjects tended towards higher levels of IL-1RA compared to recovered group (padj= 0.071). Within PCC clusters, FGF-basic and RANTES were elevated while IL-2 and MIG were decreased in PCC3 and PCC5 compared to the other PCC clusters (all p-adj< 0.04). TNF-alpha, IP-10, G-CSF and MIP-1alpha were decreased in PCC3 and PCC5 not reaching statistical significance (all p-adj=0.07). Conclusion(s): Some cytokines remained altered in all SARS-CoV-2 infected subjects independently of persistent symptoms after 6 months from acute infection. Differences between PCC and recovered individuals are limited after correction. Importantly, PCC cytokine profiles showed differences between clusters, which suggests different PCC subsyndromes with distinct etiology. Subjects Characteristics (Table Presented).
ABSTRACT
Background: Over 600 million of COVID-19 cases have been reported. A remarkable fragment of these cases are reinfections, which are mostly explained by the genomic variability of the SARS-CoV-2 variants. However, little is known about other factors fostering these reinfections. Method(s): We recorded clinical and demographic data from subjects (N=3303, March 2020 - March 2022) with at least 2 PCR+ events separated by >=90 days, analyzed by the Microbiology Department, Northern Metropolitan Clinical Laboratory from Germans Trias i Pujol Hospital (Spain). Data collected included: age, sex, comorbidities, adjusted morbidity group (GMA), hospitalization, symptomatology, NAAT (PCR, TMA) tests, antigen tests, serology, and vaccination. Temporal data was encoded using Python, and demographic characterization was performed under R. Result(s): We identified 2344 cases of confirmed reinfections, where the 2 PCR+ events were separated by >=90 days and a negative test was obtained between episodes. 72.2% of reinfected subjects were females with a median age of 45 IQR [28-63] years. Age density analysis showed three peaks at 24, 45, and 85 years, probably mostly composed of young people, who usually are less cautious, healthcare workers, and people living in nursing homes, respectively, being all of them groups prone to be tested. Regarding health status, 86.2% of participants had at least one chronic condition, with 40.5% of patients having chronic conditions in >=4 systems based on GMA assessment. Interestingly, 75.2% of reinfected subjects < 26 years had at least one chronic condition. 121 (4.2%) participants were hospitalized during a COVID-19 episode, highlighting 8.3% (N=10) of them hospitalized during the reinfection (half of them vaccinated before hospitalization), and 5% (N=6) of them during both infections. The severity of the second infection may be caused by a diminished acquired immunity after the first infection. Time between reinfections density analysis provided three peaks at ~200, ~400, and ~600 days, corresponding with time between waves. A decrease of reinfections was observed between 40 and 100 days after vaccination, which would be the period of highest protection against reinfection. Conclusion(s): SARS-CoV-2 reinfections are more prevalent among women. Importantly, people with an undermined health status, independently of age, are more sensitive to reinfections, but in most of the cases no hospitalization was required. Finally, vaccination seems to have a short protective effect on reinfection.
ABSTRACT
Introduction/Aim: Significant long-term effects on both symptomatology and respiratory function have been recognised in adult populations after COVID-19 infection, termed 'Long COVID'. These have caused loss of productivity and increased need for healthcare services. This study aimed to measure symptoms and lung function in children and adolescents after acute COVID-19 infection Methods: Between June 1 and 31 October 2021 there were 144 children admitted to hospital across the Sydney Children's Hospital Network, Australia. Of these, 63 children were referred to the respiratory clinic with symptoms of ongoing cough, shortness of breath and fatigue, 3-6 months post COVID infection. 20 of these children performed reliable lung function. For these children, body plethysmography and double diffusion testing were performed within 3-6 months of their infection. The Liverpool respiratory questionnaire and PROMIS paediatric sleep questionnaires were also administered. Result(s): Of the 20 patients tested, 7 had COVID pneumonitis requiring hospitalisation during the acute illness. 6 of the 20 patients had significant persistent symptoms as measured by the Liverpool respiratory questionnaire, while none of the children had any significant sleep symptoms. All children had preserved spirometry within normal limits. Of note, 2 children with persistent respiratory symptoms had DLNO/DLCO ratio >1.15, suggesting pulmonary vascular disease. The same two children who had elevated DLNO / DLCO had high ventilator equivalents on CPET testing suggesting increased physiological dead space ventilation. Despite this, their peak aerobic capacity was within normal limits. There were no significant differences between the alpha and delta cohorts or between children treated at home vs those requiring hospitalisation during their infection. Conclusion(s): COVID-19 may cause long-lasting effects in children. In this cohort, all children maintained spirometry results within normal limits despite significant symptoms impacting daily activities. Double diffusion testing may shed some light on lung changes leading to persistent symptomatology after COVID infection.
ABSTRACT
Purpose: To investigate the knowledge of pathology and prevention of the novel coronavirus (COVID-19), attitude towards clinical practice, and adherence to standard precautions among clinical physiotherapists during the pandemic. Material(s) and Method(s): A snowballing method was used to recruit physiotherapists (across 53 countries) who responded to a newly designed and validated survey on the participants&amp;amp;amp;amp;#x2019;demographics, knowledge of COVID-19, attitude, practices, and standard precaution adherence during the pandemic. Data were analysed using descriptive statistics, Cronbach&amp;amp;amp;amp;#x2019;s Alpha, Pearson&amp;amp;amp;amp;#x2019;s correlation, and ANOVA. Result(s): All participants (n = 2550, 100%) were knowledgeable on COVID-19 symptomatology. However, only (n = 312, 12.2%) were actively involved in the management of confirmed cases. The percentage score of participants&amp;amp;amp;amp;#x2019;knowledge regarding COVID-19 pathology, and prevention, their attitude, and adherence to standard precautions averaged 77.73 &amp;amp;amp;amp;#xb1;10.11, 89.70 &amp;amp;amp;amp;#xb1;9.26, 77.44 &amp;amp;amp;amp;#xb1;7.04, and 61.59 &amp;amp;amp;amp;#xb1;16.63, respectively. Knowledge about COVID-19 pathology differed significantly across demographic variables (p &amp;amp;amp;amp;#x003C;0.001, &amp;amp;amp;amp;#x220;2 &amp;amp;amp;amp;#x2264;0.07). Most participants (n = 1936, 75.9%) reported an inadequate supply of personal protective equipment (PPE). Conclusion(s): Participants had good knowledge of COVID-19 pathology and a positive attitude towards safe clinical practice. However, adherence to standard precautions was suboptimal due to inadequate infectious disease training and PPE supply.Copyright © 2021 Informa UK Limited, trading as Taylor &amp;amp;amp;amp;#x0026;Francis Group.
ABSTRACT
To determine prevelance of ENT symptoms in COVID 19 positive patients. A cross sectional study was performed at SRTR GMC AMBAJOGAI, a tertiary care hospital amongst the patients admitted in COVID 19 isolation ward with a positive RT-PCR report. Amongst the included 180 patients, 112 patients had one or more ENT related symptoms that included throat pain (47.2%), loss of smell (55.5%), loss of taste (58.8%) and hearing loss (54.44%) along with generalized COVID 19 symptoms. ENT symptoms can be considered as biomarkers for early diagnosis of Covid-19 patients ensuring faster treatment and isolation allowing better containment of the disease.
ABSTRACT
The research aimed to investigate the first nationwide lockdown's psychological impact (March-May 2020) on children with neurodevelopmental disorders, as well as the onset of symptomatology stress-related according to the parents.Method: An online survey has been spread on social networks for one month (July 2020) ad-dressed to parents of children with neurodevelopmental disorders. The study included 443 Italian parents, especially from Lombardy, Tuscany, Lazio and Piedmont.Results: Parents reported children's difficulties in distance learning (61,2%). Children suspended specialized interventions (62,5%). A great number of parents reported the onset of symptoms in their children: attention problems, concentration difficulties, irritability, sleep disorders and anxiety. Specifically, half of the parents revealed symptoms' worsening of children's disorder (54,4%).Conclusions: The lockdown period have had a great psychological impact on children and adolescents with neurodevelopmental disorders and a worsening of their clinical status.
ABSTRACT
Online psychological interventions (OPI) are evidence-based programs that provide mental health treatment over the internet. Meta-analytic data suggests that OPI's effectively treat emotional symptomatology. RNT-focused ACT consider psychological inflexibility and RNT as trans-diagnostic process that significantly predict emotional symptomatology. The present study analyzed the effect of a self-help OPI which contents have previously shown content validity, user feasibility and effectivity. This is an open trial design with repeated measures of emotional symptomatology and behavioral change processes. Bayesian analysis of variance for repeated measures was conducted with JASP for each variable, Bayes Factors (BF10) determined how much the evidence favored OPI effect. Effect sizes, reliable and significant change and moderation analyses were also conducted. 18 cisgender women around 30 years old mostly heterosexual, single and unemployed finished the OPI. There is decisive evidence for OPI effect on emotional symptomatology and behavioral change processes (experiential avoidance, cognitive fusion and RNT). There is also anecdotal evidence for the moderating role of the number of hierarchical RNT triggers ( private events), their type and intimate partner relationship distress as well as anecdotal evidence against the moderating role of being a psychologist. Results need to be considered in the context of the study limitations and future research should explore the program's feasibility and effect in other populations and cultures. However, the program is feasible and efficacious for the treatment of emotional symptomatology at least for young cisgender women in Colombia.
ABSTRACT
Background: Coronavirus disease-2019 (COVID-19) has caused a pandemic that has recently affected every aspect of life. Fortunately, many vaccines with high safety and efficacy profiles were developed timely to face this pandemic. In a very short time, billions of people were vaccinated. In the meantime, a wide range of neurological syndromes are being reported. Guillain-Barre syndrome (GBS) which is a rare immune-mediated post-infectious peripheral neuropathy was reported after both the COVID-19 infection itself and many types of its vaccines. Method(s): We are reporting a case of post-AstraZeneca vaccine GBS and reviewing the literature of all reported post-COVID-19 vaccines GBS till July 2021. Result(s): 29 adult patients were reported. Of them 58.6% were males. Their mean age is 58.2 years. The median time to clinical onset after vaccine administration was 13.2 days. 86.2% of patients had their symptoms following immunization with the 1st dose of AstraZeneca vector-based covid vaccine. Facial palsy was the most predominant single symptom in 75.8% of patients. Conclusion(s): Guillain-Barre syndrome is a well-recognized but still rare adverse event following vaccination against COVID-19. Although preliminary data incriminates viral vector-based vaccines more than the other types, active post-vaccination surveillance and more powerful statistics are mandatory to reach a solid conclusion regarding the presence of a causal relation.Copyright © 2022
ABSTRACT
Background: The impact of COVID-19 on mental health has been continuously reported, especially among healthcare workers. In the literature, anxiety and depressive symptoms are not uncommon in infected individuals. However, there is little data on these psychological events in healthcare professionals. Objective(s): To determine the prevalence and associated factors of anxiety and depressive symptoms in healthcare workers infected by COVID-19. Method(s): This is a cross-sectional study conducted among healthcare workers at Farhat Hached University Hospital infected by COVID 19. A self-administered questionnaire was used to collect data on the socio-professional and medical characteristics of the participants. Anxiety and depressive symptoms were assessed by the Hospital Anxiety and Depression Scale (HAD-S). Result(s): A total of 477 confirmed COVID-19 in healthcare workers were included in this study (85.9%). The mean age of the participants was 39.9 +/-10.8 years. Women represented 78.2%. The majority of the infected participants were nurses (32.1%). The paucisymptomatic form of the disease was the most frequent (73.8%). After returning to work, 62.7% of the participants retained residual symptoms and 15.5% experienced stigma reactions from their colleagues. The overall prevalence of anxiety and depressive symptoms were 25.4% and 19.1%, respectively. These identified problems were significantly interrelated. Furthermore, residual symptoms and duration of confinement predicted anxiety symptomatology, while female gender and symptomatic clinical form of COVID-19 were significantly associated with depressive symptomatology. Conclusion(s): The psychological events of COVID-19 are frequent among healthcare workers. Thus, systematic screening and early management of psychological disorders are necessary to preserve the human resources of the health sector.
ABSTRACT
Background: Cardiovascular complications are rapidly emerging as a major threat in COVID-19 infection. Nonetheless, the mechanisms underlying the disproportionate effect of SARS-CoV-2 infection on patients with cardiovascular comorbidities remain incompletely understood. Purpose(s): To assess whether COVID-19 infection has an adverse clinical outcome at medium-term follow-up. Method(s): A case-control study was performed. Cases were subjects who were diagnosed with COVID-19 infection following nasopharyhngeal swabbing. Controls were age- and gender-matched subjects who were not found to be infected with COVID-19 following swabbing and were negative on testing for COVID-19 IgG antibodies. All participants were submitted a standardised questionnaire regarding past medical history. Baseline blood investigations were taken including N-terminal pro-B-type natriuretic peptide (NT-proBNP) and troponin levels. High-sensitivity C-reactive protein (hsCRP) was taken as marker of inflammation and von Willebrand factor (vWF) was taken as marker of endothelial dysfunction. Result(s): 270 subjects were recruited, comprising 174 cases and 96 controls. Of the latter, 21 were found to be COVID-19 IgG positive and were excluded from the analysis. Hence, the study cohort comprised 174 cases and 75 controls. The mean age of the participants was 46.1+/-13.8 years. The median follow-up was of 173.5 days (IQR 129-193.25 days). There was no statistically significant difference in the baseline demographics between cases and controls with regards age, gender as well as cardiovascular risk factors and underlying medical conditions. Regarding symptomatology at follow-up, there was a statistically significant difference between the groups in deterioration in general condition (p<0.001), shortness of breath (SOB) (p=0.008), fatigue (p=0.044), arthralgia (p<0.001), abnormal taste (p<0.001) and anosmia (p<0.001), all being more frequent in subjects with prior COVID-19 infection. At follow-up, the blood investigations showed that only hsCRP was statistically significantly higher in the cases as compared to the controls (p=0.03, Figure 1). Correlation analysis consequently revealed a negative correlation in both troponin (p=0.013, r=-0.19) and vWF levels (p=0.026, r=-0.169) with time. Finally, the association between the cases experiencing dyspnoea and the blood investigations at follow-up was assessed. Multivariate analysis revealed that COVID-19 positive cases experiencing dyspnoea have significantly higher white cell count (WCC) (OR 1.22, 95% CI 1.02-1.46, p=0.029) and troponin levels (OR 1.15, 95% CI 1.02-1.29, p=0.015) and lower haemoglobin levels at follow-up (OR 0.66, 95% CI 0.5-0.86, p<0.002), Figure 2. Conclusion(s): Patients previously infected with COVID-19 have persistent symptomatology at medium-term follow-up. The role of troponin, together with markers of inflammation and endothelial dysfunction at long-term follow-up merit further investigation. (Figure Presented) .
