Evaluation of SARS-CoV-2 antibody persistence and viral spread in stool: a long-term care experience before COVID-19 vaccination.

BACKGROUND: Due to elderly residents, nursing homes/assisted living facilities were the most affected places in COVID-19 pandemic. Besides symptomatic patients, asymptomatic patients were detected during routine screening. AIM: This study aims to determine the factors that affect antibody response and viral shedding in stool samples after natural exposure to the virus in residents and staff who recovered from COVID-19 before the vaccine was available. METHODS: This prospective cross-sectional study was conducted at the nation's highest-capacity Residential and Nursing Home. Blood samples were collected between December 15, 2020 and January 15, 2021 from participating residents and staff for anti-SARS-CoV-2 antibody testing. Stool samples were obtained for SARS-CoV-2 PCR testing 2 months after COVID-19. The Social Sciences (SPSS) program version 15.0 was used for statistical analysis. The Mann-Whitney U test compared SARS-CoV-2 antibody concentration between two groups. RESULTS: Four hundred sixty-four (52.3%) residents and 424 (47.7%) staff participated. Entirely 259 (29.2%) participants were anti-SARS-CoV-2 IgG (+) and 255 (28.7%) were SARS-CoV-2 PCR (+). Both antibody and PCR positivity was detected in 196 (76.9%). In PCR (-) group, 63 (10.0%) participants were SARS-CoV-2 IgG (+). Antibody titers were found highest in SARS-CoV-2 PCR (+) male residents. SARS-CoV-2 IgG titers were significantly high in SARS-CoV-2 PCR (+) and hospitalized participants regardless of age. Stool samples were obtained from 61(23.9%) participants and were found negative. CONCLUSION: A durable SARS-CoV-2 IgG antibody response was monitored at least 9 months after the participants were diagnosed with COVID-19. SARS-CoV-2 antibody positivity was detected 76.9% in PCR (+) and 10.0% in PCR (-) participants. Knowing the duration of detectable antibodies is an important finding for developing disease prevention and public health strategies.

Prevalence of Gastrointestinal Symptoms and Clinical Outcomes in Hospitalized Coronavirus Disease 2019 Patients: A Single-Center Study from Turkey.

BACKGROUND: In patients with coronavirus disease 2019, the gastrointestinal symptoms have been reported increasingly in addition to the respiratory system symptoms. The studies show that the prevalence of gastrointestinal system symptoms and how the gastrointestinal system contributes to the severity and prognosis of the disease is still not clear. This study aims to find the prevalence of gastrointestinal symptoms and the correlation between the gastrointestinal symptoms and the clinical results in hospitalized patients diagnosed with coronavirus disease 2019. METHODS: This study retrospectively analyzes patients diagnosed with coronavirus disease 2019 and hospitalized in the pandemic unit between March 2020 and August 2020 and compares their demographic and clinical characteristics, laboratory and radiologic findings, coronavirus disease 2019 treatments received, the clinical course of the disease, and the gastrointestinal symptoms. RESULTS: In our study, we included 322 patients diagnosed with coronavirus disease 2019 and hospitalized; 39 patients (12.1%) were admitted to the hospital with at least one gastrointestinal symptom (nausea and vomiting, diarrhea, abdominal pain, and the loss of taste). Nausea and vomiting are the most common gastrointestinal symptoms with a prevalence of 7.1%, followed by diarrhea with 2.8%, the loss of taste with 2.2%, and abdominal pain with 1.5%. The mean age and D-dimer levels of the patients showing gastrointestinal symptoms were lower than those who did not have any gastrointestinal symptoms. We did not find a significant correlation between the presence of the gastrointestinal symptoms and the severity of the disease, treatment received, risk of acute respiratory distress syndrome and septic shock, admission to the intensive care unit, the need for mechanical ventilation, the mortality rate or the length of hospitalization in the medical floor or the intensive care unit. CONCLUSION: In this study, we observed that 12.1% of coronavirus disease 2019 patients apply to the hospital due to gastrointestinal symptoms. Furthermore, the gastrointestinal symptoms do not seem to affect the severity and the course of the disease, it is important to identify coronavirus disease 2019 patients showing unusual symptoms such as the gastrointestinal symptoms at an early stage to protect healthcare professionals from infection risk.

Facing the Pandemic: Burnout in Physicians in Turkey.

OBJECTIVE: During the COVID-19 pandemic, physicians have been working for long hours, with the fear of contracting the disease and infecting their families. Therefore, there are great concerns about the mental health of physicians. In this research, we aimed to reveal the factors that affect the burnout among physicians working during the pandemic. MATERIAL AND METHODS: This is a cross-sectional study involving physicians working during the pandemic in health institutions that admit COVID-19 patients. A questionnaire form consisting of the "Sociodemographic Data Form" and the "Maslach Burnout Inventory (MBI)" was used. The questionnaire was sent to the contact numbers of physicians via the internet. The target population was reached through the communication groups of the Turkish Thoracic Society and other professional associations, the communication groups of health institutions, and also through personal correspondence. Burnout was evaluated with the scores of each participant from the 3 subscales of Emotional Exhaustion (EE), Depersonalization (DP), and Lack of Accomplishment (LA). RESULTS: Of the 1177 physicians who participated in the survey, 893 answered the survey completely. Females comprised 56.70% (n = 506) of the respondents, and the mean age was 38.63 (±11.65). The residents (41%, n = 366) and specialists (31%, n = 277) made up the majority of the physicians. Eighty-six percent (n = 768) of the physicians had difficulty in obtaining personal protective equipment (PPE). It was determined that 81.7% (n = 730) of the 893 physicians were actively working in pandemic units (outpatient clinics, emergencies, inpatient clinics, intensive care units), and burnout was significantly higher in these physicians (P < .01). After excluding other confounding factors by regression analysis, their Maslach total scores and EE scores were found to be significantly high (P = .001). CONCLUSION: Working in pandemic units and facing difficulty in accessing PPE are identified as the most important risk factors for burnout. Hence, we can say that working with PPE, and with the managers' discretion and support, the physicians' burnout can be prevented.

Lung Cancer Management in COVID-19 Pandemic.

In studies published in China, lung cancer patients were identified as the greatest risk group during the COVID-19 pandemic due to their diseases and immunosuppressive treatments. Poor prognosis is anticipated if COVID-19 pneumonia is detected in lung cancer patients. Oncology associations and specialists from countries such as China and Italy have published suggestions that allow patients to experience the pandemic with minimal harm. It is recommended that patients stay in their homes and not visit the hospital. This may mean postponing treatments, switching to oral form of treatments that must continue, and extending the intervals between IV treatments or reducing the number of cycles. When surgery is required, neoadjuvant chemotherapies are preferred. It is difficult to differentiate the symptoms or radiological images of the lung cancer patient with COVID 19 pneumonia vs cancer progression or treatment-related complications. Therefore, careful examination is key. In this article, we have compiled recommendations for the management of lung cancer during the COVID 19 pandemic.
