COVID-19: booster(s) vs. hospitalization and Intensive Care Unit admission

OBJECTIVE

As the pandemic continues, different vaccine protocols have been implemented to maintain the protection of vaccines and to provide protection against new variants. The aim of this study was to assess hospitalized patients' vaccination status and document the efficacy of boosters.

PATIENTS AND METHODS

The patients that were hospitalized due to COVID-19 were enrolled from 28 hospitals in Turkey for five months from September 2021. 5,331 confirmed COVID-19 patients from collaborating centers were randomly enrolled to understand/estimate the distribution of vaccination status in hospitalized patients and to compare the efficacy of vaccination/booster protocols.

RESULTS

2,779 men and 2,552 women of which 2,408 (45.2%) were admitted to Intensive Care Units participated in this study. It was found that the highest risk reduction for all age groups was found in groups that received 4 doses. Four doses of vaccination for every 3.7 people under 50 years of age, for every 5.7 people in the 50-64 age group, and for every 4.3 people over 65 years of age will prevent 1 patient from being admitted to intensive care. Regardless of the type of vaccine, it was found that the risk of ICU hospitalization decreased in those who were vaccinated compared to those who were not vaccinated. Regardless of the type of vaccine, the ICU risk was found to decrease 1.25-fold in those who received 1 or 2 doses of vaccine, 1.18-fold in those who received 3 doses, and 3.26-fold in those who received 4 doses.

CONCLUSIONS

The results suggested that the addition of a fourth dose is more effective in preventing intensive unit care even in disadvantaged groups.

A case of fever of unknown origin: necrotizing sarcoid granulomatosis

Necrotizing sarcoid granulomatosis is a rare type of vasculitis; its etiology and pathogenesis are still unknown. The disease primarily affects the lungs, although extra-pulmonary involvement has been reported. The typical symptoms are cough, chest pain, dyspnea, and weight loss; high temperatures have been reported in rare cases. We present the case of a 65-year-old woman who was diagnosed with lymph node tuberculosis, for which she received treatment for six months. The patient experienced no improvement in her symptoms, which included fever, weakness and dyspnea. A re-evaluation of previously collected thoracoscopic biopsy material revealed compatibility with necrotizing sarcoid granulomatosis.

Role of smoke-free legislation on emergency department admissions for smoking-related diseases in Kocaeli, Turkey

Legislation banning smoking in all indoor public places was introduced in Turkey in July 2009. The aim of this study was to evaluate the role of smoke-free legislation on the number of emergency department admissions for smoking-related diseases in Kocaeli city. A retrospective analysis was made of hospital records from the first 6 months of 2009 and 2010 (before and after legislation). Total admissions for smoking-related diseases were 83 089 in 2009 and 64 314 in 2010, a 22.6% decrease. Time-series analysis showed that the decreases were significant for bronchitis and lower respiratory tract infections. Emergency admissions for chronic obstructive pulmonary disease, myocardial infarction and allergic rhinitis were lower but not significantly so. The number of patients admitted with asthma showed a non-significant increase. Smoke-free legislation might have important short-term effects on emergency department admissions, but further studies are needed in order to evaluate the long-term effects of legislation on smoking-related diseases.
