The Myth of Mild: Severe Exacerbations in Mild Asthma: An Underappreciated, but Preventable Problem.
Asthma is a common, chronic inflammatory airway disease, characterised by unpredictable episodes of worsening symptoms, or exacerbations. Causes of asthma exacerbations include viral infections, exposure to allergen and air pollution, all of which increase the underlying inflammation that typifies asthma. Most (50-75%) patients are classed as having mild asthma, with symptoms that can be readily controlled with available inhaled medications. ⋯ This commentary highlights the fact that even patients with well-controlled mild asthma are at risk of severe, potentially life-threatening exacerbations, similar to those in patients with moderate or severe asthma, and therefore 'mild asthma', is a misnomer. The commentary describes the case history of a patient with mild asthma to illustrate how increasing use of SABA alone can worsen and prolong exacerbations when they occur. The author goes on to describe how the management of this patient's exacerbation could have been improved, and provides up-to-date advice on broader aspects of the management of mild asthma and exacerbations, supported by the recent changes to the GINA recommendations.

ReviewEstimation of the Prevalence of Progressive Fibrosing Interstitial Lung Diseases: Systematic Literature Review and Data from a Physician Survey.
Some patients with interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis exhibit a progressive clinical phenotype. These chronic progressive fibrosing ILDs have a variety of underlying diseases, and their prevalence is currently unknown. Here we carry out the first systematic review of literature on the prevalence of fibrosing ILDs and progressive fibrosing ILDs using data from physician surveys to estimate frequency of progression among different ILDs. ⋯ In total, 13-40% of ILDs were estimated to develop a progressive fibrosing phenotype, with overall prevalence estimates for progressive fibrosing ILDs of 2.2-20.0 per 100,000 in Europe and 28.0 per 100,000 in the USA. Prevalence estimates for individual progressive fibrosing ILDs varied up to 16.7 per 100,000 people. These conditions represent a sizeable fraction of chronic respiratory disorders and have a high unmet need.

Observational StudyReal-World, Non-Interventional, Retrospective Study (SAMPLE) of Tolvaptan in Patients with Hyponatraemia Secondary to the Syndrome of Inappropriate Antidiuretic Hormone Secretion.
The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common cause of hyponatraemia in hospital inpatients. We present data on treatment setting, patient characteristics, and outcomes for patients treated with tolvaptan for SIADH across a range of real-world settings in Germany and Spain. ⋯ NCT02545101.

Randomized Controlled TrialPharmacokinetics, Safety and Tolerability of Once-Weekly Subcutaneous Semaglutide in Healthy Chinese Subjects: A Double-Blind, Phase 1, Randomized Controlled Trial.
Once-weekly (OW) subcutaneous (s.c.) semaglutide is an injectable glucagon-like peptide-1 (GLP-1) analogue approved for the treatment of type 2 diabetes. This trial was designed to assess the pharmacokinetics, safety and tolerability of OW s.c. semaglutide in healthy Chinese subjects. ⋯ The pharmacokinetics, safety and tolerability of OW s.c. semaglutide in healthy Chinese subjects were consistent with previous clinical pharmacology trials of OW s.c. semaglutide in other populations. The results suggest that no dose adjustment is necessary for semaglutide in Chinese patients with T2D.

ReviewClinical Challenges in the Management of Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative Metastatic Breast Cancer: A Literature Review.
Endocrine therapy (ET) is integral to the treatment of hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC). Aromatase inhibitors (AIs; e.g., anastrozole, letrozole, exemestane), selective estrogen receptor modulators (e.g., tamoxifen), and the selective estrogen receptor degrader, fulvestrant, inhibit tumor cell proliferation by targeting ER signaling. However, the efficacy of ET could be limited by intrinsic and acquired resistance mechanisms, which has prompted the development of targeted agents and combination strategies. ⋯ Recently, the combination of fulvestrant with alpelisib in phosphatidylinositol-4,5-bisphosphate 3-kinase (PIK3CA) mutated HR+, HER2- MBC following progression on or after ET was approved, based on the SOLAR-1 study. However, the optimal sequencing of treatments is unknown, especially following disease progression on a CDK4/6 inhibitor. This review aims to provide practical guidance for the management of HR+, HER2- MBC based on available data and the utility of genomic biomarkers, including germline breast cancer genes 1 and 2 (BRCA1/2) mutations, and somatic estrogen receptor alpha gene (ESR1), HER2, and PIK3CA mutations.
