The COVID-19 pandemic has brought countries’ health services into sharp focus. It was drawn to our group’s attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.

Aim: Obstructive sleep apnea syndrome (OSAS) is a chronic and incapacitating disease that often requires lifelong care. This study aimed to evaluate the thiol/disulfide homeostasis in patients with OSAS, to compare the thiol/disulfide levels with the control group and to investigate their relationship with the severity of the disease. Material and methods: Patients who were admitted to the department of chest diseases, and diagnosed with OSAS using polysomnographic analysis (n = 186) and 144 patients who underwent polysomnography due to some reasons but ruled out of having OSAS were included in the study. Serum total thiol (TT), native thiol (SH), and disulfide thiol (SS) levels were measured from the participants; SS/SH, SS/TT, and SH/TT percent ratios were calculated and compared between the patient and control groups. Results: The mean (±SD) age of the patients and control participants was 52.0 ± 11.5 years and 44.9 ± 13.2 years, respectively. Compared to the control group, patients with OSAS had significantly lower SH (239.3 ± 56.3 μmol/L vs. 258.6 ± 65.3μmol/L, t = 2.70, p =.007) and TT levels (273.2 ± 60.1 μmol/L vs. 292.9 ± 67.5μmol/L, t = 2.64, p=.010). Age (OR = 1.04), serum albumin (OR = 12.67), ischemia-modified albumin (IMA) (OR = 0.12), SH (OR = 0.81), and TT (OR = 1.17) were independent predictors of OSAS. Conclusions: These results support the idea that decreased ST and TT levels are related to increased oxidative stress. On the other hand, impaired thiol balance may play a significant role in the pathogenesis of OSAS.

Objectives: We aimed to investigate the effect of kinesiotaping (KT) on the respiratory parameters as measured by spirometry and depression in the chronic obstructive pulmonary disease (COPD) patients. Methods: In this prospective, randomized, controlled, single-blind study 42 male patients with COPD diagnosis were randomized into two groups. In Group1 (n = 21) routine COPD medical treatment plus kinesiotaping and in Group2 (n = 21) only routine COPD medical treatment was given. KT was changed on every fifth day (for a total of three times and 15 days). The patients were assessed using Visual Analog Scale (VAS) for difficulty experienced by the patients during respiration, respiratory function test (RFT), modified medical research council (mMRC) dyspnea scale and beck depression inventory (BDI). The data were obtained before treatment and posttreatment. Results: In Group 1; statistically significant improvement was found in all parameters except for FVC and FVC % following treatment compared to pretreatment values. Comparison of the difference scores (the amount of recovery between posttreatment and pretreatment) of the two groups showed significantly superior improvement in Group1 for all parameters except for FVC, FVC % and FEV1% following the treatment (p < .05). Conclusions: The results of this study showed that supplementary kinesiotaping improved respiratory function and depression significantly compared to only routine medical treatment in COPD patients who were in stable condition.

Immigration increases physical, mental, and social health problems. Emergency departments constitute resources that refugees can easily access and where they frequently present. Physicians from every specialty (chest diseases, thoracic surgery, internal diseases, etc.) may be consulted if needed. We aimed to compare demographic data and clinical characteristics of Syrian refugees and Turkish citizens in our emergency department. This study was an observational cross-sectional study. It included patients who presented to the Adult Emergency Department between April 1 and July 1, 2018. The patients were grouped into Syrian refugee and Turkish citizen groups. Patient age, gender, International Statistical Classification of Disease and Related Health Problems (ICD-10) diagnostic codes, and judicial case status were recorded from physician–patient outpatient clinic data records. Disease diagnoses and judicial cases were statistically compared between the two groups. A total of 30,749 patients presented to the emergency department during the study period. Of these, 999 were Syrian refugees. The mean ages of the Syrian refugees and Turkish citizens were significantly different. There were also differences between the two groups in the top five diagnostic codes (M79–Soft tissue disorders, J39–Other disorders of the upper respiratory tract; R51–Headache; R10–Abdominal and pelvic pain; M54–Dorsalgia). A comparison of the judicial cases also revealed a difference in mean age between the groups. Fewer specific disease diagnoses were identified among Syrian refugees. This may be explained by difficulties related to language barriers between the refugees and healthcare personnel.
