Introduction: Understanding of the patient-perceived symptom burden of small cell lung cancer (SCLC) is limited. The objective of this study was to explore patients' experiences with SCLC, identify which treatment-/disease-related symptoms have the greatest impact on their well-being, and gain caregiver perspectives.

Methods: A noninterventional, cross-sectional, multimodal, mixed methods study was conducted from April-June 2021. Adult patients with SCLC and unpaid caregivers were eligible to participate. Patients' experiences, captured via 5-day video diaries and follow-up interviews, were scored 1-10 on how bothersome the patients perceived each symptom/symptomatic adverse event. Patients indicated if they believed a symptom was disease or treatment related. Caregivers participated in an online community board.

Results: The study included nine patients (five with extensive-stage [ES] disease, four with limited-stage [LS] disease) and nine caregivers. Except for one patient/caregiver pairing, patients and caregivers were unmatched. The most common impactful symptoms in patients with ES-SCLC were shortness of breath, fatigue, coughing, chest pain, and nausea/vomiting; in LS-SCLC, these were fatigue and shortness of breath. Among patients with ES disease, SCLC had a high impact on physical (leisure/hobbies, work, sleep, ability to do household chores and errands/responsibilities outside home), social (family dynamics, extrafamilial social interaction), and emotional (mental health) aspects. Patients with LS-SCLC faced the long-term physical effects of treatment, financial implications, and emotional toll of an uncertain prognosis. SCLC had a high personal and psychologic burden among caregivers, whose duties consumed much of their time. Caregivers observed similar symptoms and impacts of SCLC as those reported by patients.

Conclusions: This study provides valuable insight into patient- and caregiver-perceived burden of SCLC and can inform the design of prospective studies. Clinicians should seek to understand patients' opinions and priorities before making treatment decisions.

Introduction: Previous studies in 2018 and 2022 have suggested increasing inpatient burden of pneumothorax and widespread variation in management. Local trends have never been elucidated. Northumbria Healthcare NHS Foundation Trust (NHCT) has a well-established pleural service, serving just over 600,000. Thus, we set up a local retrospective study to look at trends in pneumothorax presentation, management strategies, length of stay, and recurrence.

Methods: A coding search for 'pneumothorax' was performed for all patients attending NHCT between 2010 and 2020 was performed with local Caldicott approval. A total of 1840 notes were analysed to exclude iatrogenic, traumatic, and paediatric events. After excluding those cases, 580 remained for further analysis, consisting of 183 primary pneumothoraces (PSP) and 397 secondary pneumothoraces (SSP).

Results: Median age for PSP was 26.5 years (IQR 17) with 69% male, and for SSP 68 years (IQR 11.5), 62% male; 23.5% of PSP and 8.6% of SSP were never smokers. The proportion of smokers and ex-smokers has not really changed over time: > 65% every year have been smokers or ex-smokers. Yearly pneumothorax incidence shows a downward trend for PSP but upwards for SSP. Median length of stay (LoS) for PSP was 2 days (IQR 2), and SSP 5 days (IQR 8), with a clear downward trend. From 2010 to 2015 > 50% PSP were managed with drain, but in 2019-2020 at least 50% managed conservatively, with a significant reduction in aspiration. Trends of recurrence for PSP are increasing, whereas for SSP is decreasing. Seventy-six (20 PSP, 56 SSP) went for surgery at the index time with 5.3% recurrence (20% recurrence in those without surgery).

Conclusions: This is the first known analysis of pneumothorax trends in a large trust in the northeast of England. The data in this study have certain limitations, including the lack of information on the size of pneumothorax and frailty indicators that may influence the decision for conservative management. Additionally, there is a reliance on clinical coding, which can introduce potential inaccuracies, and not all patient notes were accessible for analysis. Updated larger datasets should help elucidate trends better.

Patients with coronavirus disease 2019 (COVID-19) usually suffer from post-acute sequelae of coronavirus disease 2019 (PASC). Pulmonary fibrosis (PF) has the most significant long-term impact on patients' respiratory health, called post-COVID-19 pulmonary fibrosis (PC19-PF). PC19- PF can be caused by acute respiratory distress syndrome (ARDS) or pneumonia due to COVID-19. The risk factors of PC19-PF, such as older age, chronic comorbidities, the use of mechanical ventilation during the acute phase, and female sex, should be considered. Individuals with COVID-19 pneumonia symptoms lasting at least 12 weeks following diagnosis, including cough, dyspnea, exertional dyspnea, and poor saturation, accounted for nearly all disease occurrences. PC19-PF is characterized by persistent fibrotic tomographic sequelae associated with functional impairment throughout follow-up. Thus, clinical examination, radiology, pulmonary function tests, and pathological findings should be done to diagnose PC19-PF patients. PFT indicated persistent limitations in diffusion capacity and restrictive physiology, despite the absence of previous testing and inconsistency in the timeliness of assessments following acute illness. It has been hypothesized that PC19-PF patients may benefit from idiopathic pulmonary fibrosis treatment to prevent continued infection-related disorders, enhance the healing phase, and manage fibroproliferative processes. Immunomodulatory agents might reduce inflammation and the length of mechanical ventilation during the acute phase of COVID-19 infection, and the risk of the PC19-PF stage. Pulmonary rehabilitation, incorporating exercise training, physical education, and behavioral modifications, can improve the physical and psychological conditions of patients with PC19-PF.

Systemic corticosteroids (CSs), a keystone in pulmonology, are drugs with strong antiinflammatory activity. They are cheap, easily available, and accessible, but with common and serious side effects. Moreover, the use of exogenous CSs may suppress the hypothalamic-pituitary-adrenal (HPA) axis, predisposing to adrenal insufficiency. Safe CS treatment is a challenge of pharmacological research. This narrative review examined the indications of CSs in some respiratory diseases, analyzing what types, dosages, and length of treatment are required as the dosage and duration of CS treatments need to be minimized. Chronic maintenance treatments with CSs are associated with poor prognosis, but they are still prescribed in patients with severe asthma, Chronic obstructive pulmonary disease (COPD), and interstitial lung diseases. When CS discontinuation is not possible, all efforts should be made to achieve clinically meaningful reductions. Guidelines suggest the use of methylprednisolone at a dose of 20-40 mg/day or equivalent for up to 10 days in subjects with COVID-19 pneumonia (but not other respiratory viral diseases) and respiratory failure, exacerbations of asthma, and COPD. Some guidelines suggest that CS treatment shorter than 10-14 days can be abruptly stopped, strictly monitoring subjects with unexplained symptoms after CS withdrawal, who should promptly be tested for adrenal insufficiency (AI) and eventually treated. CSs are often used in severe community-acquired pneumonia associated with markedly increased serum inflammation markers, in acute respiratory distress syndrome (ARDS), in septic shock unresponsive to hydro-saline replenishment and vasopressors, and acute exacerbations of interstitial lung diseases. As these cases often require higher doses and longer duration of CS treatment, CS tapering should be gradual and, when useful, supported by an evaluation of HPA axis function.

Introduction: Suboptimal adherence to inhaled asthma therapy is associated with poor clinical outcomes. Digital companion paired inhaler devices record medication use and provide reminders, thereby improving treatment adherence and asthma outcomes. This analysis assessed the impact of indacaterol/glycopyrronium/mometasone furoate (IND/GLY/MF) Breezhaler^® digital companion on medication adherence and symptom control in adults with asthma from Germany.

Methods: This retrospective analysis included adults (≥ 18 years) with asthma and prescribed Breezhaler digital companion. Assessments included: mean medication adherence (number of puffs taken/prescribed × 100) and change in Asthma Control Test (ACT) scores [well controlled (≥ 20), not well controlled (15-20) and poorly controlled (≤ 15)] at 1 month after the first ACT (second ACT). The percent of patients with ≥ 80% medication adherence (days 16-30 and 76-90) and the change in ACT (baseline and ≥ 30 days) were analysed.

Results: Of the 163 patients with 90 days data, ≥ 80% medication adherence was achieved in 82.8% and 72.4% of patients at months 1 and 3, respectively. Change in asthma control was examined in ~ 60% (n = 97) of patients who completed ≥ 2 ACTs through the application. At baseline, 33.0% of patients were well controlled and 53.6% were well controlled at second ACT. Furthermore, 43.3% patients reported very poor control at baseline which decreased to 22.7% at second ACT.

Conclusion: The use of IND/GLY/MF (Breezhaler) with a digital companion (sensor + application) may be associated with improved symptom control and high level of controller medication adherence in patients with asthma.

Over the past 22 years, annual GOLD Reports have documented important changes in guidance and recommendations for uniformly treating patients with chronic obstructive pulmonary disease (COPD) with the goal of improving outcomes in patients suffering from this condition. The most recent GOLD Report, released in 2023, shows continued refinement in several areas, including more precise definitions of COPD and exacerbations of COPD, a new set of parameters to assess exacerbation severity, an updated COPD assessment tool, updated guidelines for initial and follow-up treatment, new information regarding the association between pharmacological triple therapy and reduction in mortality, and new discussions of inhaler device choice and adherence to COPD medications. Whereas we do not address all of the new or updated material in GOLD's 2023 Report, we summarize key changes in GOLD's recommendations regarding inhalation therapy for stable COPD and frame these changes in the context of previous GOLD recommendations.

Introduction: GINA guidelines recommend increasing the dose of inhaled corticosteroids (ICS) as a step-up option for patients with inadequately controlled asthma at GINA step 4 [inadequately controlled asthma on medium-dose ICS/long-acting beta-2 agonist (LABA)]. The aim of this study was to compare the efficacy and safety of long-acting muscarinic antagonists (LAMA) add-on to medium-dose ICS/LABA in patients at GINA 2022 step 4.

Methods: This post hoc analysis of the IRIDIUM study evaluated the change from baseline in trough forced expiratory volume (FEV₁ ) in patients receiving medium-dose MF/IND/GLY versus high-dose MF/IND and high-dose FLU/SAL at Week 26. Other outcomes included improvement in lung functions [peak expiratory flow (PEF), forced vital capacity (FVC), forced expiratory flow between 25% and 75% of the FVC (FEF)_25-75%)], asthma control [Asthma Control Questionnaire (ACQ-7)], responder analysis (≥ 0.5 unit improvement in ACQ-7), and reduction in asthma exacerbations at Weeks 26 and 52.

Results: A total of 1930 patients were included in this analysis. Medium-dose MF/IND/GLY improved trough FEV₁ versus high-dose MF/IND (Δ 41 mL; 95% CI - 7-90) and high-dose FLU/SAL (Δ 88 mL; 95% CI 39-137) at Week 26 which were sustained until Week 52. Exacerbation rates were 16% lower with medium-dose MF/IND/GLY versus high-dose MF/IND for all (mild, moderate, and severe) exacerbations and 21-30% lower versus high-dose FLU/SAL for all (mild, moderate, and severe), moderate or severe, and severe exacerbations over 52 weeks. Further improvements in other lung functions were observed with medium-dose MF/IND/GLY. No new safety signals were identified.

Conclusion: Medium-dose MF/IND/GLY improved lung function and reduced asthma exacerbations compared to high-dose ICS/LABA and may be an undervalued option in patients at GINA 2022 step 4.

Obesity is a major comorbidity for the development and worsening of asthma. It is associated with increased disease incidence, reduced response to inhaled and systemic steroids, increased asthma exacerbations, and poor disease control. Over the past two decades, we have learned that there are clinical asthma phenotypes associated with obesity, which have unique immune, inflammatory, and metabolic disease mechanisms. The objectives of this review are to provide a brief overview of the associations and gaps between these chronic inflammatory diseases and the role that traditional therapies have on treating patients with obesity-related asthma, and to describe new clinical research of therapeutic developments targeting mechanisms that are more specific to this patient population.
