Bone quality is altered mainly by osteoporosis, which is treated with modulators of bone quality. Knowledge of their mechanisms of action is crucial to understand their effects on bone quality. The goal of our study was to compare the action of alendronate (ALN) and strontium ranelate (SrRan) on the determinants of bone quality. The investigation was performed on over 60 paired human iliac biopsies. Paired samples correspond to biopsies obtained from the same patient, one before treatment (baseline) and one after 12 months of treatment, in postmenopausal women with osteoporosis. Vibrational spectroscopy (Raman and FTIRM) and nanoindentation were used to evaluate the effect of both drugs on bone quality at the ultrastructural level. Outcomes measured by vibrational spectroscopy and nanoindentation are sensitive to bone age. New bone packets are distinguished from old bone packets. Thus, the effect of bone age is distinguished from the treatment effect. Both drugs modify the mineral and organic composition in n SrRan have differential effects on bone quality in relation to their mechanism of action.Treatment with Dextromethorphan/Quinidine (DM/Q) has demonstrated benefit on pseudobulbar affect and bulbar function in amyotrophic lateral sclerosis (ALS). The aim of this study was to assess whether DM/Q could provide long-term improvement in bulbar function and thereby prolong noninvasive respiratory management in ALS.

This prospective, case-cohort study, recruited ALS patients with bulbar dysfunction. Subjects included were compared with cross-matched historical controls. Cases received DM/Q (20/10mg twice daily) during one-year follow-up; bulbar dysfunction was evaluated with the Norris scale bulbar subscore (NBS) and bulbar subscale of AlSFRS-R (ALSFRSb).

In total, 21 cases and 20 controls were enrolled, of whom noninvasive respiratory muscle assistance failed in 6 (28.5%) patients in the DM/Q group, compared with 4 patients (20.0%) in the control group (p=0.645). Time from study onset to failure of respiratory muscle aids was 5.50+1.31 months in the DM/Q group and 5.20+1.15 months in the control group (p=0.663). The adjusted OR for the effect of treatment on failure of noninvasive respiratory muscle aids was 2.12 (95%CI 0.23-33.79, p=0.592). In the DM/Q group an impairment in scores was found in NBS (F=19.26, p=0.000) and ALSFRS-Rb (F=12.71, p=0.001) across different months of the study.

Treatment with DM/Q in ALS is unable to prolong noninvasive respiratory management, and moreover, has no effect on long-term deterioration of bulbar function. Notwithstanding the results on bulbar function, DM/Q was found to improve pseudobulbar affect during one-year follow-up.

Acute exacerbation (AE) of interstitial lung disease (ILD) is an acute respiratory deterioration of unknown etiology, associated with high mortality. Currently, bronchoalveolar lavage (BAL) has been no longer required for the diagnosis of AE-ILD; however, the clinical utility of BAL fluid (BALF) cellular analysis in AE-ILD remains unclear.

A retrospective study of 71 patients who underwent BAL at our institution between 2005 and 2019 and were diagnosed with AE-ILD was conducted. We performed BALF cellular analysis and evaluated its prognostic significance.

There were 26 patients with AE of idiopathic pulmonary fibrosis (IPF) and 45 with AE of non-IPF, including idiopathic interstitial pneumonias/non-IPF (n=22), ILD associated with collagen tissue disease (n=20) and fibrotic hypersensitivity pneumonia (n=3). All patients were treated with high-dose corticosteroids, and the 90-day mortality after AE was 31%. Most patients showed a high percentage of lymphocytes and/or neutrophils in BALF regardless of the underlying ILD. There was a significant negative correlation between BALF neutrophils and the PaO

ratio, and patients with UIP pattern or diffuse AE pattern on HRCT had a significantly higher percentage of BALF neutrophils than those with other patterns. Multivariate analysis revealed that lower and higher percentage of lymphocytes and neutrophils, respectively, in BALF were independent poor prognostic factors for 90-day survival. BALF lymphocyte and neutrophil count ≥25% and <20%, respectively, predicted favorable survival after AE.

Cellular analysis of BALF in AE-ILD is a potential biomarker for predicting prognosis after AE.

Most patients suffer from respiratory disease which progresses to the severe acute respiratory syndrome, termed as SARS-CoV-2 pneumonia. A systemic inflammatory response occurs in SARS-CoV-2 pneumonia severely ill patients, The inflammation process if uncontrolled has a detrimental effect, and the release of cytokines play an important role leading to lung fibrosis. Radiation therapy used in low doses has an anti-inflammatory and immunomodulatory effect. Its low cost, wider availability, and decreased risk of acute side effects can reduce the burden on the health care system.

Rehabilitation after acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is beneficial, but its feasibility is questionable. Feasibility is potentiated by stakeholder involvement during program development. https://www.selleckchem.com/products/baxdrostat.html We aimed to explore the perspectives of various stakeholders towards an innovative rapid access rehabilitation (RAR) program for patients immediately following hospitalization for an AECOPD.

Semi-structured interviews were conducted with patients recently hospitalized for AECOPD, healthcare professionals (HCP) and policymakers providing care for such patients. Thematic analysis was performed.

Three patients (1 female; 62-89 years; GOLD D), ten HCP (3 females, 31-71 years) and three policymakers (3 females, 38-55 years) participated. Patients, HCP and policymakers shared similar visions for the development of a RAR program. Five main themes and ten subthemes were identified. They comprised Pre-RAR aspects (Management properties, Eligibility), RAR program (Outcomes, Structure, Components), RAR optimization (Referral, Uptake), Partnership (Collaboration, Dedicated Coordinator) and COVID-19 (Adaptations).
