Comparison of teachers' voice disorders before and during COVID-19 pandemic.

<b> Aim:</b> The aim of the study was to analyze the impact of the COVID-19 pandemic and the related change of the teaching mode from stationary to distance learning on the severity of voice-related ailments among teachers. </br></br> <b> Materials and methods:</b> A questionnaire survey of teachers was conducted to assess voice disorders during stationary and remote work using the Vocal Tract Discomfort (VTDs) scale and Numeric Rating Scale (NRS), and the respondents' subjective feelings were assessed. Demographic and environmental factors associated with voice work were examined. Data on sickness absence, which were obtained from the "Health Needs Maps 2020" Ministry of Health's, were also analyzed. Responses were subjected to statistical analysis. A P-value level below 0.05 was considered statistically significant. </br></br> <b>Results:</b> 128 teachers participated in the survey. The overall assessment of voice disorders using VTDs and NRS scales showed no statistically significant differences for complaints between stationary and remote work. Detailed analysis revealed more se-vere voice disorders in teachers working more than 6 months remotely (P = 0.049) and having more than 20 lessons per week (P = 0.012). Subjective assessment confirmed a significantly lower percentage of teachers reporting voice disorders when wor-king remotely compared to stationary (P = 0.043). This resulted in less sickness absence and a 40% decrease in sick leave related to voice disorders in 2020 compared to 2019. </br></br> <b>Conclusions:</b> During the remote learning period of the COVID-19 pandemic, teachers reported lower severity of voice disor-ders and this influenced the reduction of sickness absences. There were no statistically significant differences in voice complaints as assessed by VTDs and NRS scales for both teaching modes. Several factors affecting the severity of vocal tract disorders were identified - the number of class hours per week (>20) for stationary teaching and a long period of remote teaching (>6 months).

Implementation of Telemedicine in Indonesian Urology Practice During COVID-19 Pandemic: a National Survey.

BACKGROUND: The pandemic of COVID-19 is nowhere from over, which pushes us to adapt to it.  Social distancing rules were applied to restrict the people and prevent virus transmission. Despite these restrictions, the patient's care should not be compromised. Doctors are encouraged to technologically improve themselves to get used to the utilization of telemedicine. METHODS: We conducted an online survey of urology specialists and urology residents throughout the country. The survey was accompanied by the Indonesian Urological Association, and the survey was opened for one month and sent by email to all members of the association. RESULTS: A total of 50 urologists and 182 urology residents participated. Almost half (48%) currently do not have facilities to hold a telemedicine practice in their institution, and 14% reported inadequate facilities. The majority reveals that the barrier to conducting this method was due to insufficient facility. Other issues like insurance coverage and patient's interest in telemedicine, the risk of patient's data leak, and the urologist's lack of interest in telemedicine might also be challenging. Despite some doubts, in sum, more than half have thought that telemedicine would keep utilized although the pandemic is resolved. CONCLUSIONS: We are currently learning the novel telemedicine implementation and some challenges still need to be resolved. Starting from the regulation and legal protection fundamentally, and the health insurance coverage needs to be determined. After all, the low interest in adopting this method has become the greatest barrier.

Arrhythmogenesis and COVID-19.

The ongoing coronavirus infection-2019 (COVID-19) global pandemic has had devastating impacts on the global population since 2019. Cardiac complications are a well-documented sequala of COVID-19, with exposed patients experiencing complications such as myocardial infarction, myocarditis, and arrythmias. This article aims to review prominent literature regarding COVID-19 and its link with arrhythmias, as well as to discuss some of the possible mechanisms by which arrhythmogenesis may occur in patients with COVID-19.

Neurologic manifestations associated with COVID-19: a multicentre registry.

OBJECTIVES: To provide an overview of the spectrum, characteristics and outcomes of neurologic manifestations associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: We conducted a single-centre retrospective study during the French coronavirus disease 2019 (COVID-19) epidemic in March-April 2020. All COVID-19 patients with de novo neurologic manifestations were eligible. RESULTS: We included 222 COVID-19 patients with neurologic manifestations from 46 centres in France. Median (interquartile range, IQR) age was 65 (53-72) years and 136 patients (61.3%) were male. COVID-19 was severe or critical in 102 patients (45.2%). The most common neurologic diseases were COVID-19-associated encephalopathy (67/222, 30.2%), acute ischaemic cerebrovascular syndrome (57/222, 25.7%), encephalitis (21/222, 9.5%) and Guillain-Barré syndrome (15/222, 6.8%). Neurologic manifestations appeared after the first COVID-19 symptoms with a median (IQR) delay of 6 (3-8) days in COVID-19-associated encephalopathy, 7 (5-10) days in encephalitis, 12 (7-18) days in acute ischaemic cerebrovascular syndrome and 18 (15-28) days in Guillain-Barré syndrome. Brain imaging was performed in 192 patients (86.5%), including 157 magnetic resonance imaging (70.7%). Among patients with acute ischaemic cerebrovascular syndrome, 13 (22.8%) of 57 had multiterritory ischaemic strokes, with large vessel thrombosis in 16 (28.1%) of 57. Brain magnetic resonance imaging of encephalitis patients showed heterogeneous acute nonvascular lesions in 14 (66.7%) of 21. Cerebrospinal fluid of 97 patients (43.7%) was analysed, with pleocytosis found in 18 patients (18.6%) and a positive SARS-CoV-2 PCR result in two patients with encephalitis. The median (IQR) follow-up was 24 (17-34) days with a high short-term mortality rate (28/222, 12.6%). CONCLUSIONS: Clinical spectrum and outcomes of neurologic manifestations associated with SARS-CoV-2 infection were broad and heterogeneous, suggesting different underlying pathogenic processes.

Guidelines for Urological Surgeries in the COVID-19 Pandemic: Is it Time for Revision?

In this correspondence the authors try to show that guidelines and recommendations including what was published by EAU rapid reaction group must be further updated and tailored according to different epidemiologic data in different countries. The authors assign the countries worldwide in three categories. First category comprises countries that experience the secondary surges smoother than the first one. The second category include countries with stronger or -merging and rising-secondary surges and the third category encompasses countries with successful initial response and secondary stronger but still more controllable surges. Authors proclaim that after passing the first baffling impact we find out that postponement strategies preached in many of these scout treatises are no more suitable at least for the countries delineated in the second category and can culminate in performance of procedures in worse. The authors proffer Iranian Urology Association COVID-19 Taskforce Pamphlet(IUA-CTP) as a paragonic document mentioning it's the time we must recognise the wide variability of the situation in different regions and any advisory position must consider this huge variance in epidemiologic profile.

Implications of Frailty in COVID-19.

As the global coronavirus disease-19 (COVID-19) pandemic caused by severe acute respiratory distress syndrome coronavirus 2 continues to cause higher mortality and hospitalization rates among older adults, strategies such as frailty screening have been suggested for resource allocation and clinical management. Frailty is a physiologic condition characterized by a decreased reserve to stressors and is associated with disability, hospitalization, and death. Measuring frailty can be a useful tool to determine the risk and prognosis of COVID-19 patients in the acute setting, and to provide higher quality of care for vulnerable individuals in the outpatient setting. A literature review was conducted to examine current research regarding frailty and COVID-19. Frailty can inform holistic care of COVID-19 patients, and further investigation is needed to elucidate how measuring frailty should guide treatment and prevention of COVID-19.

SARS-CoV-2 Impairs Vision.

OBJECTIVES: Affection of the central nervous system and the eyes is increasingly recognized as manifestations of a SARS-CoV-2 infection (COVID-19). This review aims at summarizing and discussing recent advances concerning causes and locations of impaired vision because of an infection with SARS-CoV-2. METHODS: On a literature search through PubMed and ScholarOne, all available publications about COVID-19 patients with impaired vision were retrieved. RESULTS: Visual impairment in SARS-CoV-2-infected patients may be due to infection of lacrimal glands (dacryoadenitis), conjunctivitis, tonic pupils, vitritis, central retinal artery/venous occlusion, retinitis, retinal bleeding, panuveitis, anterior ischemic optic neuropathy, optic nerve stroke, optic neuritis, optic perineuritis, or occipital ischemic stroke. Visual impairment may be the initial manifestation of SARS-CoV-2. CONCLUSIONS: This mini review shows that impaired vision may be the initial manifestation of COVID-19, that all sections of the visual tract may be affected and causative for visual impairment in COVID-19 patients, and that SARS-CoV-2 manifests along the visual tract with ischemia, focal infection, and immunological reactions.

Popular health surveillance in traditional fishing communities and the ecology of knowledges in the fight against COVID-19. / Vigilância popular da saúde nas comunidades pesqueiras tradicionais e ecologia dos saberes no enfrentamento à COVID-19.

Considering the public health emergency of international importance caused by COVID-19, artisanal fishing workers, engaging in a dialogue with Brazilian leaders and scholars, created an Observatory on the impacts of this pandemic on fishing communities in March 2020. The purpose of this article is to analyze the experience of popular surveillance of fishermen and fisherwomen's health through daily reports produced at the Observatory. It is a monitoring process that allowed broadening the recognition of the diversity of vulnerable populations' ways of life that intertwine health, environment and work. The study used a qualitative, horizontal and emancipatory methodology and sought approaches to the practice of the ecology of knowledges, with the following results: shared construction of information and knowledges based on heterogeneous social experiences; practice of collective ombudsman with the appreciation of knowledges built in social struggles); joint assessment of public health inequities, territorial conflicts, and environmental, structural, and institutional racism; guidance of social leaders and fundraising through public notices. Thus, the dynamics and horizontality of learning based on solidarity and social emancipation from inter-knowledge are revealed.

Diante da emergência em saúde pública de importância internacional provocada pela COVID-19, trabalhadores da pesca artesanal, em diálogo com lideranças e acadêmicos brasileiros criaram, em março de 2020, um Observatório sobre os impactos dessa pandemia em comunidades pesqueiras. O objetivo deste artigo é analisar a experiência de vigilância popular da saúde de pescadores e pescadoras através de boletins diários produzidos no Observatório. Trata-se de um processo de monitoramento que possibilitou ampliar o reconhecimento da diversidade de modos de vida das populações vulneráveis que entrelaça saúde, ambiente e trabalho. O estudo utilizou metodologia qualitativa, horizontal e emancipatória e buscou aproximações à prática da ecologia dos saberes, tendo como resultados: construção compartilhada de informações e conhecimentos com base em experiências sociais heterogêneas; prática da ouvidoria coletiva com a valorização de saberes construídos nas lutas sociais; avaliação conjunta de iniquidades em saúde pública, conflitos territoriais e racismo ambiental, estrutural e institucional; orientação das lideranças sociais e captação de recursos através de editais públicos. Revela-se, assim, dinamicidade e horizontalidade de aprendizados com base na solidariedade e emancipação social a partir do interconhecimento.

COVID-19 and the liver: overview.

On 12 March 2020, the WHO declared that the coronavirus disease 2019 (COVID-19) constitutes a pandemic. Cases of liver damage or dysfunction (mainly characterized by moderately elevated serum aspartate aminotransferase levels) have been reported among patients with COVID-19. However, it is currently uncertain whether the COVID-19 related liver damage/dysfunction is due mainly to the viral infection by itself or other coexisting conditions, such as the use of potentially hepatotoxic medications and the coexistence of systemic inflammatory response, respiratory distress syndrome-induced hypoxia, and multiple organ dysfunction. Individuals at high risk for severe COVID-19 are typical of older age and/or present with comorbid conditions such as diabetes, cardiovascular disease, and hypertension. This is also the same profile for those at increased risk for unrecognized underlying liver disease, especially nonalcoholic fatty liver disease. This could make them more susceptible to liver injury from the virus, medications used in supportive management, or hypoxia. So the aim of this review was to illustrate the clinical implications of COVID-19 on the liver in healthy and diseased states as well as the implications of common liver disorders on the outcome of COVID-19.

COVID-19 in South Korea.

A novel coronavirus (severe acute respiratory syndrome-CoV-2) that initially originated from Wuhan, China, in December 2019 has already caused a pandemic. While this novel coronavirus disease (COVID-19) frequently induces mild diseases, it has also generated severe diseases among certain populations, including older-aged individuals with underlying diseases, such as cardiovascular disease and diabetes. As of 31 March 2020, a total of 9786 confirmed cases with COVID-19 have been reported in South Korea. South Korea has the highest diagnostic rate for COVID-19, which has been the major contributor in overcoming this outbreak. We are trying to reduce the reproduction number of COVID-19 to less than one and eventually succeed in controlling this outbreak using methods such as contact tracing, quarantine, testing, isolation, social distancing and school closure. This report aimed to describe the current situation of COVID-19 in South Korea and our response to this outbreak.

How Governor Directives Changed Health Workforce Flexibility in Response to the COVID-19 Pandemic.

OBJECTIVES: In times of heightened population health needs, the health workforce must respond quickly and efficiently, especially at the state level. We examined state governors' executive orders related to 2 key health workforce flexibility issues, scope of practice (SOP) and licensing, in response to the COVID-19 pandemic. METHODS: We conducted an in-depth document review of state governors' executive orders introduced in 2020 in all 50 states and the District of Columbia. We conducted a thematic content analysis of the executive order language using an inductive process and then categorized executive orders by profession (advanced practice registered nurses, physician assistants, and pharmacists) and degree of flexibility granted; for licensing, we indicated yes or no for easing or waiving cross-state regulatory barriers. RESULTS: We identified executive orders in 36 states containing explicit directives addressing SOP or out-of-state licensing, with those in 20 states easing regulatory barriers pertaining to both workforce issues. Seventeen states issued executive orders expanding SOP for advanced practice nurses and physician assistants, most commonly by completely waiving physician practice agreements, while those in 9 states expanded pharmacist SOP. Executive orders in 31 states and the District of Columbia eased or waived out-of-state licensing regulatory barriers, usually for all health care professionals. CONCLUSION: Governor directives issued through executive orders played an important role in expanding health workforce flexibility in the first year of the pandemic, especially in states with restrictive practice regulations prior to COVID-19. Future research should examine what effects these temporary flexibilities may have had on patient and practice outcomes or on permanent efforts to relax practice restrictions for health care professionals.

Development and validation of a prediction model based on comorbidities to estimate the risk of in-hospital death in patients with COVID-19.

Background: Most existing prognostic models of COVID-19 require imaging manifestations and laboratory results as predictors, which are only available in the post-hospitalization period. Therefore, we aimed to develop and validate a prognostic model to assess the in-hospital death risk in COVID-19 patients using routinely available predictors at hospital admission. Methods: We conducted a retrospective cohort study of patients with COVID-19 using the Healthcare Cost and Utilization Project State Inpatient Database in 2020. Patients hospitalized in Eastern United States (Florida, Michigan, Kentucky, and Maryland) were included in the training set, and those hospitalized in Western United States (Nevada) were included in the validation set. Discrimination, calibration, and clinical utility were evaluated to assess the model's performance. Results: A total of 17 954 in-hospital deaths occurred in the training set (n = 168 137), and 1,352 in-hospital deaths occurred in the validation set (n = 12 577). The final prediction model included 15 variables readily available at hospital admission, including age, sex, and 13 comorbidities. This prediction model showed moderate discrimination with an area under the curve (AUC) of 0.726 (95% confidence interval [CI]: 0.722-0.729) and good calibration (Brier score = 0.090, slope = 1, intercept = 0) in the training set; a similar predictive ability was observed in the validation set. Conclusion: An easy-to-use prognostic model based on predictors readily available at hospital admission was developed and validated for the early identification of COVID-19 patients with a high risk of in-hospital death. This model can be a clinical decision-support tool to triage patients and optimize resource allocation.

Spatial heterogeneity and infection patterns on epidemic transmission disclosed by a combined contact-dependent dynamics and compartmental model.

Epidemics, such as COVID-19, have caused significant harm to human society worldwide. A better understanding of epidemic transmission dynamics can contribute to more efficient prevention and control measures. Compartmental models, which assume homogeneous mixing of the population, have been widely used in the study of epidemic transmission dynamics, while agent-based models rely on a network definition for individuals. In this study, we developed a real-scale contact-dependent dynamic (CDD) model and combined it with the traditional susceptible-exposed-infectious-recovered (SEIR) compartment model. By considering individual random movement and disease spread, our simulations using the CDD-SEIR model reveal that the distribution of agent types in the community exhibits spatial heterogeneity. The estimated basic reproduction number R0 depends on group mobility, increasing logarithmically in strongly heterogeneous cases and saturating in weakly heterogeneous conditions. Notably, R0 is approximately independent of virus virulence when group mobility is low. We also show that transmission through small amounts of long-term contact is possible due to short-term contact patterns. The dependence of R0 on environment and individual movement patterns implies that reduced contact time and vaccination policies can significantly reduce the virus transmission capacity in situations where the virus is highly transmissible (i.e., R0 is relatively large). This work provides new insights into how individual movement patterns affect virus spreading and how to protect people more efficiently.

Effects of media exposure on PTSD symptoms in college students during the COVID-19 outbreak.

Objective: We aimed to investigate the influence of media on college students' mental health during the COVID-19 pandemic. Methods: After the COVID-19 outbreak, we used cross-sectional surveys through online questionnaires to investigate the mental health of college students in lockdown at home. We identified the influencing factors of PTSD symptoms using the Chi-Square test and ordinal logistic regression analysis. Results: In 10,989 valid questionnaires, 9,906 college students with no PTSD symptoms, 947 college students with subclinical PTSD symptoms (1-3 items), and 136 college students with four or more PTSD symptoms were screened out. The results showed that media content impacted the mental health of college students in lockdown at home. Positive media content was negatively correlated with PTSD symptoms among college students. PTSD symptoms were not associated with sources of information. Moreover, College students with PTSD symptoms would reduce their willingness to learn and could not complete online learning efficiently. Conclusion: PTSD symptoms are related to media exposure and excessive information involvement of COVID-19 in college students, which influences the willingness to attend online classes.
