COVID-19 in the working environment and its consequences on the health of workers

ABSTRACT This study showed the consequences of the new Coronavirus in the working environment and its effects on workers’ health. SARS-CoV-2 has a high transmission level through exhaled droplets, affecting organs such as the lungs, heart, liver, kidneys, and brain. Productive and social activities were interrupted, but many continued to operate due to market pressure. Health professionals are among the most exposed, but activities requiring many people in the same environment are at substantial risk of exposure to Coronavirus. Work can favor and accelerate the destruction caused by the virus. Inadequate economic and social policies contributed to the deterioration of the health crisis, increasing the economic and social crisis, marked by the loss of jobs and increased work instability. Control and prevention measures are required to reduce risk, but they should consider the nature of relationships in the work and social environment. Social isolation, hand hygiene, and masks are recommended measures, besides Personal Protective Equipment and collective measures for workers. The impact of the pandemic marks every worker involved. Several stressors arise or deteriorate, psychologically affecting many employees. Returning to work with adequate planning requires safety to minimize risks and protect workers.

Covid-19 no ambiente de trabalho e suas consequências à saúde dos trabalhadores

RESUMO Este trabalho apresentou as consequências do novo coronavírus no ambiente de trabalho e reflexos na saúde do trabalhador. O Sars-CoV-2 possui elevado nível de transmissão pelas gotículas exaladas, afetando órgãos como pulmões, coração, fígado, rins e cérebro. Atividades produtivas e sociais foram interrompidas, mas muitas seguiram operando por pressão do mercado. Profissionais da saúde estão entre os mais expostos, porém atividades que exigem grande número de pessoas no mesmo ambiente se encontram sob risco elevado de exposição ao novo coronavírus. O trabalho pode favorecer e acelerar a destruição causada pelo vírus. Políticas econômicas e sociais inadequadas contribuíram para agravamento da crise sanitária, aumentando a crise econômica e social, marcada pela perda de postos de trabalho e aumento da precarização do trabalho. Controles e medidas de prevenção são necessários para a redução de risco, mas precisam contemplar a natureza das relações no ambiente de trabalho e sociais. Isolamento social, higienização das mãos e uso de máscaras são providências recomendadas, além de Equipamentos de Proteção Individual e medidas coletivas para trabalhadores. O impacto da pandemia marca cada trabalhador envolvido, diversos estressores surgem ou se agravam, afetando psicologicamente muitos funcionários. O retorno ao trabalho com planejamento adequado requer segurança para minimizar riscos e proteger os trabalhadores.

Nurses' Perceptions of Oral Health Care Provision After the COVID-19 Lockdown

OBJECTIVE

This study aimed to investigate nurses' perceptions of oral health care provision to inpatients in Japanese hospitals and the infection control measures taken by them after the coronavirus disease 2019 (COVID-19) lockdown to promote collaborative oral health care.

METHOD

The participants were 1037 nurses working in inpatient wards at 4 hospitals in Fukuoka Prefecture, Japan. Data were collected through a questionnaire survey approximately 6 months after the first COVID-19 lockdown.

RESULTS

More than 90% of the 734 nurses participating in this study positively perceived the preventive effect of oral health care on aspiration pneumonia, ventilator-associated pneumonia, and viral infection. However, approximately half of them had negative perceptions about their knowledge and confidence regarding the control of COVID-19 with oral health care provision, and 84.7% expected to be provided with the necessary information by oral health professionals. Further, 537 nurses (73.2%) provided oral health care to their patients; 9 nurses (1.7%) responded that those patients who received oral health care decreased after the lockdown; and 12 (2.4%) responded that they could no longer collaborate with oral health professionals because of the lockdown. Additionally, 41.7% of them used neither protective glasses nor face shields even after the lockdown began.

CONCLUSIONS

This study showed that almost all the nurses perceived the benefcial effect of oral health care for the prevention of viral infection and pneumonia. However, some nurses perceived that their oral health care provision and collaborative oral health care were negatively affected. It also showed that most nurses' knowledge, confidence, and use of infection control measures were insufficient. The results indicate that oral health professionals should support nurses in providing oral health care by providing them with information on COVID-19 infection control measures to prevent infection transmission.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2): a Systemic Infection

To date, seven identified coronaviruses (CoVs) have been found to infect humans; of these, three highly pathogenic variants have emerged in the 21st century. The newest member of this group, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first detected at the end of 2019 in Hubei province, China. Since then, this novel coronavirus has spread worldwide, causing a pandemic; the respiratory disease caused by the virus is called coronavirus disease 2019 (COVID-19). The clinical presentation ranges from asymptomatic to mild respiratory tract infections and influenza-like illness to severe disease with accompanying lung injury, multiorgan failure, and death. Although the lungs are believed to be the site at which SARS-CoV-2 replicates, infected patients often report other symptoms, suggesting the involvement of the gastrointestinal tract, heart, cardiovascular system, kidneys, and other organs; therefore, the following question arises: is COVID-19 a respiratory or systemic disease? This review aims to summarize existing data on the replication of SARS-CoV-2 in different tissues in both patients and ex vivo models.

Potential Interaction Between SARS-CoV-2 and Thyroid: A Review

The novel coronavirus disease 2019 (COVID-19) produced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is sweeping the world in a very short time. Although much has been learned about the clinical course, prognostic inflammatory markers, and disease complications of COVID-19, the potential interaction between SARS-CoV-2 and the thyroid is poorly understood. In contrast to SARS-CoV-1, limited available evidence indicates there is no pathological evidence of thyroid injury caused by SARS-CoV-2. However, subacute thyroiditis caused by SARS-CoV-2 has been reported for the first time. Thyroid dysfunction is common in patients with COVID-19 infection. By contrast, certain thyroid diseases may have a negative impact on the prevention and control of COVID-19. In addition, some anti-COVID-19 agents may cause thyroid injury or affect its metabolism. COVID-19 and thyroid disease may mutually aggravate the disease burden. Patients with SARS-CoV-2 infection should not ignore the effect on thyroid function, especially when there are obvious related symptoms. In addition, patients with thyroid diseases should follow specific management principles during the epidemic period.
