[Determination of anthropometric measurements in obstructive sleep apnea syndrome in Turkish population]. / Türk popülasyonunda obstrüktif uyku apne sendromunda rol oynayan antropometrik ölçümlerin belirlenmesi.

INTRODUCTION: In this study, we aimed to determine the values of anthropometric measurements and rates used in the evaluation of obstructive sleep apnea syndrome (OSAS) in our country. MATERIALS AND METHODS: Twenty accredited sleep centers in thirteen provinces participated in this multicenter prospective study. OSAS symptoms and polysomnographic examination and apnea-hypopnea index (AHI) ≥ 5 cases OSAS study group; patients with AHI < 5 and STOP-Bang < 2 were included as control group. Demographic characteristics (age, sex, body mass index-BMI) and anthropometric measurements (neck, waist and hip circumference, waist/hip ratio) of the subjects were recorded. RESULT: The study included 2684 patients (81.3% OSAS) with a mean age of 50.50 ± 0.21 years from 20 centers. The cases were taken from six geographical regions of the country (Mediterranean, Eastern Anatolia, Aegean, Central Anatolia, Black Sea and Marmara Region). Demographic characteristics and anthropometric measurements; age, neck, waist, hip circumference and waist/ hip ratios and BMI characteristics when compared with the control group; when compared according to regions, age, neck, waist, hip circumference and waist/hip ratios were found to be statistically different (p< 0.001, p< 0.001, p< 0.05, respectively). When compared by sex, age, neck and hip circumference, waist/hip ratio, height, weight and BMI characteristics were statistically different (p< 0.001, respectively). Neck circumference and waist/hip ratio were respectively 42.58 ± 0.10 cm, 0.99 ± 0.002, 39.24 ± 0.16 cm, 0.93 ± 0.004 were found in women. CONCLUSIONS: The neck circumference was lower than the standard value in men, but higher in women. The waist/hip ratio was above the ideal measurements in both men and women. In this context, the determination of the country values will allow the identification of patients with the possibility of OSAS and referral to sleep centers for polysomnography.

The Role of Pneumococcal Pneumonia among Community-Acquired Pneumonia in Adult Turkish Population: TurkCAP Study.

OBJECTIVE: To evaluate the rate of pneumococcal pneumonia (PP) among patients with community-acquired pneumonia (CAP) in Turkey and to investigate and compare features of PP and non-PP CAP patients. MATERIAL AND METHODS: This multicenter, non-interventional, prospective, observational study included adult CAP patients (age ≥ 18 years). Diagnosis of PP was based on the presence of at least 1 positive laboratory test result for Streptococcus pneumoniae (blood culture or sputum culture or urinary antigen test [UAT]) in patients with radiographic findings of pneumonia. RESULTS: Four hundred sixty-five patients were diagnosed with CAP, of whom 59 (12.7%) had PP. The most common comorbidity was chronic obstructive pulmonary disease (30.1%). The mean age, smoking history, presence of chronic neurological disease, and CURB-65 score were significantly higher in PP patients, when compared to non-PP patients. In PP patients, 84.8% were diagnosed based ony on the UAT. The overall rate of PP patients among CAP was calculated as 22.8% considering the UAT sensitivity ratio of 63% (95% confidence interval: 45-81). The rate of intensive care treatment was higher in PP patients (P = .007). While no PP patients were vaccinated for pneumococcus, 3.8% of the non-PP patients were vaccinated (P = .235). Antibiotic use in the preceding 48 hours was higher in the non-PP group than in the PP group (31.8% vs. 11.1%, P = .002). The CURB-65 score and the rate of patients requiring inpatient treatment according to this score were higher in the PP group. CONCLUSION: The facts that PP patients were older and required intensive care treatment more frequently as compared to non-PP patients underline the burden of PP.

The Prevalence of Asthma-COPD Overlap (ACO) Among Patients with Asthma.

OBJECTIVES: Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) is defined as a persistent airflow limitation with features of both asthma and COPD. However, in Turkey, there are limited data about ACO. The aims of the present study were to determine the prevalence of ACO among patients with asthma, to compare the clinical characteristics of patients with ACO and asthma, and to determine the threshold values for the diagnosis of ACO. MATERIALS AND METHODS: The study group comprised 338 patients admitted to the outpatient clinics between 2010 and 2017 and who had undergone at least three pulmonary function tests within the last 2 years. Patients aged >40 years with a smoking history of >10 pack-years or biomass exposure, with at least three features of both diseases, and with reversible and persistent airflow limitation were diagnosed with ACO. The study is a retrospective study so we did not get informed concent. RESULTS: Asthma-chronic obstructive pulmonary disease overlap was diagnosed in 40 (11.8%) patients. Patients with ACO had fewer allergic comorbidities, worse spirometric parameters, and required higher doses of inhaled corticosteroids than patients with asthma only (p<0.05). No significant differences were observed between the groups regarding survival or number of hospitalizations and attacks (p>0.05). Threshold values were determined as age ≥57.5 years, smoking history ≥14 pack-years, and diagnosis at age ≥40.5 years. CONCLUSION: The frequency of ACO was observed to be very high in patients with asthma. In patients >57.5 years old, with a smoking history of >14.5 pack-years, and diagnosed with asthma at >40.5 years old, the probability of ACO diagnosis increases.
