Strategies to mitigate bias are discussed and recommended. We introduce what we believe can be a powerful teaching tool periodic "bias and racism rounds" in teaching hospitals, in which real patient interactions are reviewed critically to identify opportunities to reduce bias and racism and to attenuate the impact of bias and racism on patient outcomes. Gastroesophageal reflux disease is a common comorbidity in idiopathic pulmonary fibrosis (IPF) and may contribute to its progression. Anti-acid therapy, such as proton pump inhibitors (PPIs), has been considered as a potential treatment option for IPF. The evidence for this treatment comes from several observational studies affected by time-related bias. Is use of PPIs in patients with IPF associated with a reduction in all-cause mortality, respiratory-related mortality, and respiratory-related hospitalization? We used the UK Clinical Practice Research Datalink to identify a cohort of patients diagnosed with IPF between 2003 and 2016. The prevalent new-user cohort design was used to match patients initiating PPIs with non-users using time-conditional propensity scores, with follow-up until death or end of observation. Cox models were used to estimate hazard ratios (HR) and 95%CIs of death and of a respiratory-related hospitalization, correcting for informative censoring by inverse probability weighting.elated biases affecting previous studies. PPIs may not be as beneficial in treating IPF as suggested by some studies and conditionally recommended in treatment guidelines. Vasodilatory shock refractory to catecholamine vasopressors and arginine vasopressin is highly morbid and responsible for significant mortality. Synthetic angiotensin II is a potent vasoconstrictor that may be suitable for use in these patients. What is the safety and effectiveness of angiotensin II and what variables are associated with a favorable hemodynamic response? We performed a multicenter, retrospective study at five tertiary medical centers in the United States. The primary end point of hemodynamic responsiveness to angiotensin II was defined as attainment of mean arterial pressure (MAP) of≥ 65mmHg with a stable or reduced total vasopressor dosage 3h after drug initiation. Of 270 included patients, 181 (67%) demonstrated hemodynamic responsiveness to angiotensin II. Responders showed a greater increase in MAP (+10.3mmHg vs+1.6mmHg, P< .001) and reduction in vasopressor dosage (-0.20 μg/kg/min vs+0.04 μg/kg/min; P< .001) compared with nonresponders at 3 h. Variables associated with favoiotensin II. Patients who responded to angiotensin II experienced reduced mortality. Benralizumab is an IL5-receptor monoclonal antibody licensed for the treatment of severe eosinophilic asthma (SEA). It has demonstrated efficacy in clinical trials in reducing asthma exacerbation rates and maintenance oral corticosteroids (mOCSs). What is the real-world effectiveness of benralizumab and what baseline characteristics are associated with response to therapy? We assessed outcomes in all SEA patients who began benralizumab treatment at our specialist center. At each dosing visit, exacerbation history, mOCS dose, spirometry, and Asthma Control Questionnaire (ACQ6) and Mini-Asthma Quality of Life Questionnaire (mAQLQ) scores were recorded. Response to treatment was defined as a reduction of≥ 50%in annualized exacerbation rate (AER) or in mOCS dose after 48weeks of treatment. Super response was defined as zero exacerbations and no mOCSs for asthma. One hundred thirty patients were included in the analysis. At 48weeks, a 72.8%reduction in AER was noted, from 4.92 ± 3.35 per year in the year pved in 5 of 18 patients. In a large real-world SEA cohort, benralizumab led to significant improvements in all clinical outcome measures. A lack of response was seen in a minority of patients and should be a focus for future investigation.In a large real-world SEA cohort, benralizumab led to significant improvements in all clinical outcome measures.

Participation in life roles is a critical patient-centered health outcome associated with morbidity and mortality in older adults, but it is not measured routinely in people with COPD. We aimed to validate a participation measure, the Late Life Disability Instrument (LLDI), in people with COPD. To what extent does the LLDI demonstrate test-retest measurement error and reliability, internal consistency, construct and face validity, and floor or ceiling effects when applied to people with COPD? In this cross-sectional study, LLDI scores were compared with scores on measures of theoretically related constructs and between groups based on symptom severity, prognosis, and frailty. A subsample (n= 36) completed the LLDI a second time over the phone within one week. Participants and health-care professionals were asked about the relevance, comprehensiveness, and comprehensibility of the LLDI. Floor and ceiling effects were explored, and the internal consistency (Cronbach's α) of the LLDI was calculated. Ninend face validity in people with COPD.

A lobectomy is the standard of care for most patients with operable lung cancer and accounts for 60% to 70% of lung resection. The chest radiograph may appear normal after a lobectomy, particularly in uncomplicated cases. However, lobectomy usually involves leaving surgical staples at the bronchial stump and causes various changes in the intra- and extrapulmonary thoracic structures on plain radiographs. These changes may differ according to the resected lobe. We retrospectively evaluated the plain radiographic appearances of the postlobectomy chest, free of postoperative complications or recurrent/metastatic lung cancer. AM580 On the basis of our observations, the changes that occur in pulmonary and extrapulmonary anatomy can differ according to the resected lobe. Recognition of these changes will make it easier to identify which lobe has been removed surgically.
