Introduction In a subset of chronic obstructive pulmonary disease (COPD)patients the course of the disease is complicated by a severe acute exacerbations (AECOPD) that may require hospitalization, at which time negative outcomes may occur up to 30 days after discharge. Several predictors of negative outcomes have been documented.Areas covered We considered five negative outcomes related to patients hospitalized with AECOPD treatment failure, non-invasive mechanical ventilation (NIMV) failure, prolonged length of hospital stay (LHS), short-term mortality (≤ 90 days from admission and including the in-hospital mortality), and early readmission (≤30 days from discharge). Possible therapeutic and preventive strategies to improve these outcomes are outlined and discussed.Expert opinion Several strategies have been proposed to improve outcomes. Among these, steroid or antibiotic use may reduce the risks of treatment failure or of prolonged hospital stay. We note that operator-related factors may influence the outcome of NIMV. However, little has been documented about the short-term mortality or early readmission rates. In general, few interventions consistently improve negative outcomes and prognosis of AECOPD.Introduction Allogeneic hematopoietic stem cell transplantation (HSCT) remains the cornerstone of curative approach to myelofibrosis (MF), although it is burdened by not negligible toxicity and mortality.Areas covered In this review, authors discuss the status-of-the-art of HSCT in MF, emphasizing the current limits and the areas for improvement. We interrogated public databases for papers published in the last 30&nbsp;years.Expert opinion The therapeutic landscape of MF has been revolutionized after the approval of JAK inhibitor ruxolitinib, which showed impressive efficacy in reducing splenomegaly and ameliorating symptoms and quality of life. Unfortunately, the disease-modifying activity of ruxolitinib is modest, with most patients ultimately dying due to disease progression. Identification of potential candidates to HSCT is critical in order to balance risks and expected benefits, and should rely on risk scores specifically developed to such purpose. The use of ruxolitinib as bridge to HSCT might increase the proportion of patients ultimately able to undergo the procedure and possibly improve their outcome, and represents an important area of research. Since MF is a disease of middle age, further improvements should aim to reduce toxicity of the HSCT procedure and expand the use of alternative, particularly haploidentical, donors.Introduction Anemia is a common extraintestinal complication of Crohn's disease (CD) mainly caused by iron deficiency, that affects the quality of life in CD patients. Elucidation of the etiology and pathology of iron-deficiency anemia (IDA) and anemia of chronic diseases (ACD) has developed in recent years. Common biochemical parameters of iron status are insufficient for assessment of patients with anemia and CD. Thus, novel iron indices are required for accurate assessment in IDA patients with CD. Oral iron supplementation for IDA treatment is common and is associated with minor gastrointestinal side effects. Intravenous substitution improves safety profiles but may be not tolerable in some patients. Fortunately, additional therapies for anemia of active CD have emerged in recent years.Area covered Here, we propose the review article on the link among anemia, iron deficiency, and Crohn's disease. We discuss the current diagnosis and therapy of anemia and iron deficiency in CD and propose the new directions for future research.Expert commentary Exploring pathogeneses and treatments of anemia and iron deficiency in Crohn's disease will develop potential tools for early diagnosis and effective treatment of anemia in CD patients, and improve their life quality.Introduction Hidradenitis suppurativa (HS) is a chronic skin disorder characterized by inflammatory nodules, abscesses, and fistulae. Patients tend to present in young adulthood and are predominantly female. The pathogenesis of HS involves apopilosebaceous gland follicle occlusion and affected areas often occur where this type of gland predominates. Treatment selection depends on HS severity, which is included in different scoring systems. In recent years, biological therapies have been evaluated and used with increasing frequency in moderate-to-severe HS disease.Areas covered This review focuses on biological therapies for HS as assessed in case reports, case series, and clinical trials. The efficacy, hidradenitis suppurativa scoring systems, and long-term results of these therapies are discussed depending on the studies' endpoints.Expert opinion Adalimumab is currently the only FDA-approved HS biological therapy. Some patients do not experience treatment efficacy with adalimumab at 40 mg/week, which may result in increasing the dose or seeking other treatments. Infliximab is the next line of HS treatment with demonstrated efficacy. Other biological therapies being studied have demonstrated efficacy in small patient groups, but lack study power. Further studies may provide answers to seeking treatment options for patients who fail to improve on current standard HS treatment.Introduction Severe alcohol-associated hepatitis (sAH) portends high morbidity and mortality and there are no effective therapies for those ineligible or unresponsive to corticosteroids. Early liver transplantation (LT) defined as transplantation without a mandated period of sobriety, for sAH, is being increasingly considered as a rescue therapy.Areas covered PubMed and manual searches were combined and last performed on 28 October 2019. Key search terms were 'alcoholic hepatitis', 'abstinence', 'alcohol relapse', and 'liver transplantation'. Terms were combined within each database. General reviews and references from published trials were also used.Expert opinion Early LT is indicated in highly selected patients with sAH. While long-term data are sparse, 1 and 3-year survival post-transplantation are excellent and comparable to other liver diseases. [https://www.selleckchem.com/products/gm6001.html Selleckchem Ilomastat] Alcohol relapse is uncommon but approaches 10-25% at 3&nbsp;years and if use is heavy and/or sustained leads to reduced survival. Thus, for continued application of transplantation for this indication, there is a need to further refine selection criteria and to optimize management of alcohol use disorder (AUD) in the transplant setting.
