Studies are showing that pulmonary rehabilitation (PR) increases diaphragmatic excursion by decreasing hyperinflation in patients with chronic obstructive pulmonary disease (COPD). However, there is a lack of knowledge about its effects on the diaphragm thickness (dt) and contractility. This study aims to evaluate the dt and contractility before and after PR in patients with COPD. ⋯ A total of 34 patients with a mean age and FEV1 61.05 ± 8.22 years and 57.9 ± 20.4% predicted respectively showed improvements in exercise capacity and some items of PFT and SGRQ. Diaphragmatic thickness at the end of the expiration also significantly improved regardless of the disease severity and was positively correlated with functional performance. The 6-weeks of PR didn't result in a significant difference in diaphragm contractility.

JAK2V617F mutation is expressed in almost all polycthemia vera (PV), 55% of essential thrombocythemia (ET), and 65% of primary myelofibrosis (PMF) patients. Studies investigating phenotypic effects of JAK2V617F mutation on Philadelphianegative myeloproliferative neoplasms (Ph-negative MPNs) have reported controversial results. This study aims to determine the impact of JAK2V617F mutation on clinical phenotype and outcome in Ph-negative MPNs. ⋯ In PV patients, JAK2V617F mutation was associated with higher rate in females, lower hemoglobin (Hgb) level, higher leukocyte and platelet count and higher prevalence of thrombosis (p = 0.008, p = 0.018, p = 0.001, p = 0.001, and p = 0.035, respectively). In ET patients, JAK2V617F mutation was associated with higher Hgb and hematocrit (Hct) levels and lower platelet count (p = 0.001, p = 0.001, and p = 0.001, respectively). JAK2V617F-negative ET patients showed a trend towards higher rate of leukemic transformation (p = 0.061). JAK2V617F mutation-positive PMF patients had higher leukocyte count, greater spleen size and showed a trend towards higher Hgb level (p = 0.019, p = 0.042, and p = 0.056, respectively). Among PMF patients with JAK2V617F mutation, the rate of female patients was lower (p = 0.001). Overall survival (OS) in Dynamic International Prognostic Scoring System (DIPSS) - plus high risk PMF patients was shorter compared to the other risk groups (p = 0.001). Leukemia-free survival (LFS) was shorter in DIPSS - plus high risk PMF patients than the other risk groups (p = 0.005). In the entire cohort of Ph-negative MPN patients, JAK2V617F mutation was associated with higher leukocyte count, higher Hgb and Hct levels and lower platelet count, higher frequency of phlebotomies, a trend towards older age, a trend towards greater spleen size, a trend towards a higher prevalence of risk factors for cardiovascular diseases and thrombosis (p = 0.001, p = 0.005, p = 0.001, p = 0.003, p = 0.004, p =0.052, p = 0.056, p = 0.052, and p = 0.059, respectively).

This study aimed to develop the Nausea and Vomiting Thermometer Scale (NVTS) in children with cancer. ⋯ The scale-level content validity index was .94, which was coherent. As a result of the ROC analysis, the cut-off point was determined as three points. The NVTS showed good reliability, with an intra-class correlation coefficient of .99. In the linear regression analysis, a model was created for chemotherapy drugs, nausea and vomiting type, vomiting status, and the number of children with cancer who vomited explained 44.9% of their nausea and vomiting status. The results of the Bland-Altman analysis showed that the correlation coefficient between the differences and the means was insignificant.

Fine-needle non-aspiration cytology (FNNAC) is an easy-to-apply, minimally invasive diagnostic method that contributes to the diagnosis and staging of lung cancer. FNNAC can be performed from peripheral lymph nodes as well as in peripheral lung lesions. This study aimed to evaluate the contribution of FNNAC performed from peripheral lesions or lymph nodes to diagnosis in patients with pulmonary malignant lesions. ⋯ The mean age of 56 patients, two female (3.6%) and 54 male (96.4%), was 63.9 ± 9.1 (38-80) years. FNNAC was performed from the peripheral lymph node in 48 patients, the peripheral pulmonary lesion in four, and the accompanying chest wall lesion in four. While true positivity was present in 42 patients, two patients had true negativity, and 12 had false negativity. In five of the 12 cases reported as false negative, the collected material was evaluated as insufficient, while the malignant diagnoses of the remaining seven cases were confirmed by other diagnostic methods. The diagnostic success of FNNAC was determined as 78.57% (95% CI: 65.56-88.41). FNNAC was more successful in diagnosis when performed from the peripheral lymph node compared to the peripheral pulmonary lesion (p=0.033).

A high D-dimer level may indicate the risk of coagulopathy and mortality in COVID-19 patients. T hromboelastography (TEG) is a test that evaluates clot formation and fibrinolysis in real-time, unlike routine coagulation tests. The study aimed to investigate the coagulation process with TEG in patients diagnosed with COVID-19. ⋯ D-dimer and fibrinogen levels of the HDG were higher than those of the LDG (550 vs. 90 ng/mL, p < 0.001; 521 vs. 269 mg/ dL, p < 0.001, respectively). In TEG analysis, HDG's R and K values were lower than LDG, and HDG's Angle, MA, and CI values were higher than LDG (p = 0.037; p < 0.001; p < 0.001; p < 0.001; p < 0.001, respectively). ROC curve analysis suggested that the optimum TEG parameters cut-off points for thrombosis risk were as below: for K was ≤2.1 min, for R was ≤6.1 min, for Angle was >62°, MA was 60.4 mm.
