COVID-19-Related Stigma and Mental Health of Children and Adolescents During Pandemic.

This cross-sectional study aimed to evaluate depression and anxiety symptoms of the children/grandchildren of COVID-19 patients, children/grandchildren of healthcare workers who have not infected COVID-19, and children/grandchildren of the control group. Parent and children's perception about COVID-19-related stigma is also investigated and compared between groups. The perception about COVID-19-related stigma between different age and gender groups among children also investigated and compared. The mental health of the 71 participants aged 6-18 years was evaluated via a telemedicine-based semi-structured interview between March and April 2020. Children's Depression Inventory (CDI), the Screen for Child Anxiety-Related Emotional Disorders (SCARED), and COVID-19-Related Stigma Form were administered to the participants. A significant negative correlation was found between age and separation anxiety disorder (p = .005) and a significant positive correlation was found between age and generalized anxiety disorder (p = .035) in the SCARED-Child report. Generalized anxiety disorder was found to be higher in females compared to males. A significant difference was found between the groups of parents in the COVID-19-Related Stigma Form. Patients infected with COVID-19, healthcare workers, and the control group have different perceptions about COVID-19-related stigma. The age of the children have an impact on stigma perceptions. Anxiety symptoms of children affected by age and gender. Future studies are recommended to determine the other factors associated with perceptions about COVID-19-related stigma among children and parents.

Clinical Outcome of PCR-Negative COVID-19 Patients: A Retrospective Study.

OBJECTIVE: To evaluate the clinical features and outcomes of patients who were admitted with a diagnosis of coronavirus disease 2019 (COVID-19) but who were not confirmed with polymerase chain reaction (PCR) positivity. MATERIAL AND METHODS: This is a retrospective analysis of all patients admitted to two tertiary care centers between March 15 and May 15, 2020, with a diagnosis of COVID-19. From a common database prepared for COVID-19, we retrieved the relevant data and compared the clinical findings and outcomes of PCR-positive patients with those of PCR-negative cases who had been diagnosed on the basis of typical clinical and radiographic findings. RESULTS: A total of 349 patients were included in the analysis, of which 126 (36.1%) were PCR-negative. PCR-negative patients were younger (54.6 ± 20.8 vs. 60.8 ± 18.9 years, P = .009) but were similar to PCR-positive patients in terms of demographics, comorbidities, and presenting symptoms. They had higher lymphocyte counts (1519 ± 868 vs. 1331 ± 737/mm3, P = .02) and less frequently presented with bilateral radiographic findings (68.3% vs. 79.4%, P = .046) than PCR-positive patients. Besides, they had less severe disease and better clinical outcomes regarding admission to the intensive care unit (9.6% vs. 20.6%, P = .023), oxygen therapy (21.4% vs. 43.5%, P < .001), ventilatory support (3.2% vs. 11.2%, P = .03) and length of hospital stay (5.0 ± 5.0 vs. 9.7 ± 5.9 days, P < .001). CONCLUSION: This study confirms that about one-third of the COVID-19 patients are PCR-negative and diagnosed based on clinical and radiographic findings. These patients have a more favorable clinical course, shorter hospital stays, and are less frequently admitted to the intensive care unit.

Plasma and bronchoalveolar lavage fluid levels of endothelin-1 in patients with chronic obstructive pulmonary disease and pulmonary hypertension.

BACKGROUND: Secondary pulmonary hypertension (PH) and cor pulmonale are the major clinical cardiovascular complications affecting prognosis in patients with chronic obstructive pulmonary disease (COPD). It is also known that endothelin-1 (ET-1) is a potent vasoconstrictor peptide produced by the pulmonary vascular endothelium, and ET-1 may be implicated in the pathogenesis of PH. OBJECTIVES: The purpose of this study was to investigate the presence of ET-1 in patients with COPD and to assess the correlation of ET-1 levels in the plasma and bronchoalveolar lavage (BAL) fluid (BALF) in COPD patients with or without PH. METHODS: Twenty-two patients with COPD and 15 healthy controls were enrolled in the study. Peripheral venous blood samples were collected in all patients and controls. BAL was obtained in COPD patients, and ET-1 levels were measured by radioimmunoassay in all plasma and BALF samples. RESULTS: Plasma ET-1 levels were 2.46 +/- 0.55 and 1.70 +/- 0.42 pmol/dl in patients with COPD and controls, respectively (p < 0.0001). Sixteen of the 22 patients with COPD (73%) had PH established by echocardiography. The ET-1 level in these patients amounted to 2.59 +/- 0.50 pmol/dl, and it was 2.10 +/- 0.54 pmol/dl in 6 patients with COPD without PH. In COPD patients with and without PH, BALF ET-1 levels were 0.19 +/- 0.08 and 0.24 +/- 0.01 pmol/dl, respectively (p > 0.05). CONCLUSIONS: These results suggest that ET-1 is detectable in both the peripheral blood and BALF of COPD patients, but the levels do not statistically differ between patients with and without PH.
