5 ± 2.6 years were included. No significant differences were found between groups regarding lung function, asthma control, quality of life, and functional tests. Ventilatory equivalent for oxygen consumption at ventilatory threshold (P = .025; η p 2  = 0.083), peak oxygen consumption (P = .008; η p 2  = 0.116) and test duration (P = .014; η p 2  = 0.1) presented greater improvements in the IG. In addition, improvements were observed in leg press (P  less then  .001; η p 2  = 0.36), hamstring curl (P = .001; η p 2  = 0.217), high row (P = .003; η p 2  = .167), low row (P = .009; η p 2  = 0.128) and quadriceps leg extension (P = .015; η p 2  = 0.108) in the IG. CONCLUSION Combined exercise training (resistance and aerobic) improved cardiorespiratory fitness and muscle strength in children and adolescents with controlled asthma and exercise symptoms. © 2020 Wiley Periodicals, Inc.OBJECTIVE To study impulse oscillometry (IOS) indices of peripheral airway function and FeNO as predictors of future loss of asthma control in preschool children. METHODS Patients aged 3 to 6 years who were actively being treated for asthma and children without asthma were enrolled in the study. Participants had no change in medication on visit 1 and returned for a follow-up visit within 8 to 12 weeks. At the first visit, nursing assessment, symptom history, IOS analysis, FeNO, and physician evaluation were repeated. RESULTS Fifty-one (64.6%) subjects had lost asthma control (UC-Group) and 28 (35.4%) subjects had maintained asthma control (C-Group) at their follow-up visit. Thirty-two children without asthma were enrolled in the study as a normal control group (N-Group). R5, R5-20, AX, and Z5 values were all significantly higher in subjects whose symptoms remained uncontrolled compared with those in the controlled asthma group (P  less then  .01) and also significantly higher than those in the normal control group (P  less then  .01). FeNO showed no significant difference between the UC-Group and C-Group (P = .399). Four indices-R5, R5-20, AX, and Z5-had an estimated area under the curve (AUC) of greater than 0.8 and were thus easily able to distinguish the UC-Group from the C-Group. CONCLUSIONS AX had the highest overall AUC (0.884) of the investigated parameters, and the optimal cut-off point of 37.435 cm H2 O/L was able to predict future loss of asthma control in preschool children. © 2020 Wiley Periodicals, Inc.Cellular homeostasis requires tight coordination between nucleus and mitochondria, organelles that each possesses their own genomes. Disrupted mitonuclear communication has been found to be implicated in many aging processes. However, little is known about mitonuclear signaling regulator in sarcopenia which is a major contributor to the risk of poor health-related quality of life, disability, and premature death in older people. High-temperature requirement protein A2 (HtrA2/Omi) is a mitochondrial protease and plays an important role in mitochondrial proteostasis. HtrA2mnd2(-/-) mice harboring protease-deficient HtrA2/Omi Ser276Cys missense mutants exhibit premature aging phenotype. Additionally, HtrA2/Omi has been established as a signaling regulator in nervous system and tumors. We therefore asked whether HtrA2/Omi participates in mitonuclear signaling regulation in muscle degeneration. Using motor functional, histological, and molecular biological methods, we characterized the phenotype of HtrA2mnd2(-/-) peroxisome proliferator-activated receptor γ coactivator 1α. These results reveal that loss of HtrA2/Omi protease activity induces mitonuclear imbalance via differential regulation of mitochondrial biogenesis in sarcopenia. The novel mechanistic insights may be of importance in developing new therapeutic strategies for sarcopenia. © 2020 International Union of Biochemistry and Molecular Biology.Low blood pressure is common in patients with heart failure and reduced ejection fraction (HFrEF). While spontaneous hypotension predicts risk in HFrEF, there is only limited evidence regarding the relationship between hypotension observed during heart failure (HF) drug titration and outcome. Nevertheless, hypotension (especially orthostatic hypotension) is an important factor limiting the titration of HFrEF treatments in routine practice. In patients with signs of shock and/or severe congestion, hospitalization is advised. However, in the very frequent cases of non-severe and asymptomatic hypotension observed while taking drugs with a class I indication in HFrEF, European and US guidelines recommend maintaining the same drug dosage. In instances of symptomatic or severe persistent hypotension (systolic blood pressure  less then  90 mmHg), it is recommended to first decrease blood pressure reducing drugs not indicated in HFrEF as well as the loop diuretic dose in the absence of associated signs of congestion. Unless the management of hypotension appears urgent, a HF specialist should then be sought rather than stopping or decreasing drugs with a class I indication in HFrEF. selleck kinase inhibitor If symptoms or severe hypotension persist, no recommendations exist. Our HF group reviewed available evidence and proposes certain steps to follow in such situations in order to improve the pharmacological management of these patients. © 2020 The Authors.

The Papanicolaou Society of Cytopathology (PSC) has already outlined a categorical system for reporting respiratory cytology. Though each category has a known malignancy risk, their inter observer reproducibility have not been well documented. This study was directed towards establishing the reproducibility of this categorical system in diagnosing pulmonary lesions. METHOD One hundred and one consecutive cytology specimens obtained by CT-guided FNA from lung lesions were independently reviewed by 3 experienced cytopathologists, who allotted each case to 1 of 6 PSC categories. Statistical analysis for percent overall agreement was done using Fleiss' Kappa. RESULT Percent overall agreement was 71.29% and free marginal kappa was 0.66. On combining categories "suspicious" and "malignant" percent overall agreement was 79.54% and free marginal kappa was 0.74. CONCLUSION There was substantial agreement among the observers as regards reproducibility of categories which can improve if we combine certain categories, especially "suspicious" and "malignant.
