Multinomial Regression Analysis

The causes of the broad spectrum of severity in COVID-19 are unknown. A protective effect through humoral immunity from previous infections by viruses of the SARS-CoV-2 family could explain a mild form of this disease. This study aimed to address whether the presence of antibodies against human seasonal coronaviruses (HCoVs) could prevent severe manifestations of COVID-19. A cross-sectional study was carried out in 165 participants. The presence of pre-existent antibodies against the seasonal HCoV-OC43, HCoV-HKU1, HCoV-229E, and HCoV-NL63 were detected. From all of the seasonal HCoVs studied, it was only found that being seropositive to HCoV-229E presented an association (p = 0.012) with developing mild clinical symptoms of COVID-19 or being asymptomatic. Multinomial regression analysis showed that being seropositive to HCoV-229E is associated with mild or moderate clinical symptoms for COVID-19. Statistical analysis also showed that being female is associated with being asymptomatic for SARS-CoV-2 infection or developing mild COVID-19. A subgroup analysis taking only seropositive to HCoV-229E revealed that females are more likely to develop asymptomatic SARS-CoV-2 infection (OR = 27.242, 95% CI 2.092–354.706, p = 0.012). Our results suggest that previous infections by HCoV-229E could prevent more serious clinical manifestations of COVID-19, but these are not the only variables that influence this event.

Abstract In developed and developing countries, most cases of acute gastroenteritis in children are caused by viruses, and rotaviruses are known as the leading cause. The aim of our study was to estimate the main circulating serotypes of rotavirus before the introduction of routine immunisation in Latvia, and to search for their possible correlation with clinical symptoms and circulating genotypes. A cross-sectional study was carried out among children who had been hospitalised in the Children’s Clinical University Hospital from April 2013 to December 2015. Genotyping was done for 462 stool samples. Among G/P combinations, the most predominant genotypes were G4P[8] (61.3%), G9P[8] (12.4%) and G2P[4] (10.0%) in children of age < 5 years, G4P[8] (45.5%), G2P[4] (18.2%), G9P[8], G3P[8], and G1P[8] (9.1%) in children of age > 5 years. There was a statistically significant correlation (p < 0.05) between clinical signs (vomiting, dehydration, chronic diseases) and G1P[8] and G8P[8] genotypes. Infants infected with genotype G4P[4] had a statistically significant negative correlation with severity of acute gastroenteritis episodes (p < 0.05). We detected nine different rotavirus G genotypes, and two different P genotypes. G4P[8], G9P[8], and G2P[8] were predominant. We observed correlation between the dominant genotypes and clinical manifestations of rotavirus infection.

Background: The cytology and the support of clinical symptoms, biochemistry for diagnosis of the cases of effusions are very important. Objectives: - To describe some of clinical symptoms and biochemistry of effusions. - To compare the results between cytology and biochemistry by the causes of pleural, peritoneal fluids. Material & Method: A cross-sectional study to describe all of 47 patients with pleural, peritoneal effusions examinated by cytology in the Hospital of Hue University of Medicine and Pharmacy from April 2013 to January 2014. Results: In 47 cases with effusions, pleural effusion accounting for 55.32%, following peritoneal effusions 29.79% and 14.89% with both of them. The most common symptoms in patients with pleural effusions were diminished or absent tactile fremitus, dull percussion, diminished or absent breath sounds (100%), in patients with peritoneal effusions was ascites (95.24%). 100% cases with pleural effusions, 50% cases with peritoneal effusions and 80% cases with pleural and peritoneal effusions were exudates. The percentage of malignant cells in patients with pleural effusions was 26.92%, in peritoneal effusions was 28.57%, in pleural and peritoneal effusions was 42.86%. The percentage of detecting the malignant cells in patients with suspected cancer in the first test was 57.14%, in the second was 9.53% and 33.33% undetectable. Most of cases which had malignant cells and inflammatory were exudates, all of the cases which had a few cells were transudates. Besides, 7.5% cases which had high neutrophil leukocytes were transudates. Conclusion: Cytology should be carry out adding to the clinical examinations and biochemistry tests to have an exact diagnosis, especially for the malignant ones. For the case with suspected cancer, we should repeat cytology test one more time to increase the ability to detect malignant cells.

Background: Hyponatremia is associated with unfavorable outcomes in many cases. The mainstay of hyponatremia treatment depends on its symptoms and etiology. However, etiologies, clinical manifestations, and factors associated with severe symptomatic hyponatremia have been rarely reported. Objective: To analyze and report etiologies, clinical manifestations, and factors associated with severe symptomatic hyponatremia. Materials and Methods: In the present cross-sectional study, the authors enrolled hospitalized patients with hyponatremia who had consulted a nephrologist between October 1, 2017, and October 31, 2018. Their baseline characteristics and clinical manifestations were recorded. Etiologies were confirmed by the attending nephrology staff. Factors associated with severe symptomatic hyponatremia were evaluated using logistic regression analysis. Results: One hundred patients were included in this study. The syndrome of inappropriate antidiuresis (SIAD), hypovolemia, and hydrochlorothiazide use were the leading hyponatremia etiologies. Hyponatremia etiologies differed between patients with community-acquired hyponatremia (n=50) and those with hospital-associated hyponatremia (n=50). Patients with communityacquired hyponatremia were older, presented with a higher frequency of severe symptomatic hyponatremia, and showed lower SNa-levels. Low SNa-levels were significantly associated with severe symptomatic hyponatremia (p=0.014). Conclusion: Hyponatremia remains an important health problem. SIAD, hypovolemia, and hydrochlorothiazide use are among the leading etiologies of hyponatremia. Low SNa-levels are associated with severe symptomatic hyponatremia; thus, physicians should pay close attention to low SNa-levels in hospitalized patients.

Background: COVID-19 has spread globally with remarkable speed, and currently, there is limited data available exploring any aspect of the intersection between HIV and SARSCoV- 2 co-infection. Objective: To estimate the prevalence of clinical symptoms associated with COVID-19 among people living with HIV (PLWH) in Tehran, Iran. Design: Cross-sectional study. Methods: A total of 200 PLWH were recruited through the positive club via sampling, and completed the symptom-based questionnaire for COVID-19, which was delivered by trained peers. Results: Of 200 participants, respiratory symptoms, including cough, sputum, and shortness of breath, were the most prevalent among participants, but only one person developed symptoms collectively suggested COVID-19 and sought treatments. Conclusions: It appears that existing infection with HIV or receiving antiretroviral treatment (ART) might reduce the susceptibility to the infection with SARS-CoV-2 or decrease the severity of the infection acquired. Further research is needed to understand causal mechanisms.

Abstract Individuals providing unpaid care of assistance to family members and friends (e.g. informal caregivers), may have been uniquely impacted by the COVID-19 pandemic. Research is needed to examine the pandemic’s effect on informal caregivers’ caregiving intensity and burden. Therefore, this cross-sectional study was conducted to explore self-reported changes in caregiver intensity (CI) and caregiver burden (CB) due to the pandemic to identify factors associated with changes in responsibilities and burdens. In June 2020, informal caregivers providing care to someone aged 50+ (n=835) reported their current and pre-pandemic caregiving intensity and burden. Data were collected via Amazon’s Mechanical Turk. Chi-square tests were used to examine bivariate associations between pandemic time (pre vs. post) differences in CI and CB. Multinomial regression was used to assess multivariate predictors of changes to CI and CB due to COVID-19. Results showed a significant U-shaped association between initial CB and CB change due to COVID-19. Higher levels of initial CB were associated with both a significant decrease in CB during COVID-19 (OR 1.33, 95%CI 1.06-1.67), and a significant increase in CB during COVID-19 (OR 1.22, 95%CI 1.05-1.43). There were no significant associations between initial CB and changes in CI due to COVID-19, although older caregivers were more likely to experience a decrease in CB due to caregiving (OR 1.02, 95%CI 1.00-1.05). These mixed results suggest that caregivers with high initial CB experienced the most extreme changes to CB due to COVID-19. Future planned analyses will focus on understanding the potential drivers behind these unexpected results.
