Behaviour change interventions for physical activity in adults with chronic obstructive pulmonary disease; A systematic review and meta-analysis.

Background: Physical activity in adults with COPD is poor, but behaviour change interventions could help improve activity. This systematic review aims to examine behaviour change interventions to promote physical activity and health outcomes for adults with COPD.

Methods: Eight databases were searched from inception until April 2023: Web of Science, CENTRAL, MEDLINE, EMBASE, APA PsychINFO, CINAHL, PROSPERO, Cochrane Airways Trials Register.

Behaviour change and physical activity interventions for physical activity engagement in community dwelling adults with chronic obstructive pulmonary disease: protocol for a systematic review.

Chronic obstructive pulmonary disease (COPD) is a complex respiratory disease and the third leading cause of death worldwide. Pulmonary rehabilitation is recognised as the gold standard of care in the management of COPD, however engagement with pulmonary rehabilitation is low and maintenance of a physically active lifestyle in community dwelling adults with COPD is poor. Supporting positive behaviour change in people with COPD could help to increase their engagement with physical activity.

Fluctuating hypercalcaemia caused by cavitary pulmonary infection.

Hypercalcaemia occurs in many granulomatous diseases. Among them, sarcoidosis and tuberculosis are the most common causes. Other causes include berylliosis, coccidioidomycosis, histoplasmosis, Crohn's disease, silicone-induced granulomas, cat-scratch disease, Wegener's granulomatosis and pneumonia.

Bilateral Chylothorax Secondary to Retrosternal Goitre: a Case Report and Review of the Literature.

Unlabelled: Chylothorax is characterized by an accumulation of lymphatic fluid in the pleural cavity due to damage to the thoracic duct. The aetiology can be traumatic or non-traumatic. Goitre is a rare cause of chylothorax with only eight cases previously described in the literature including only one case causing a bilateral chylothorax.

Biomarkers to identify ILD and predict lung function decline in scleroderma lung disease or idiopathic pulmonary fibrosis.

Background: SSc-ILD and IPF demonstrate significant morbidity and mortality. Predicting disease progression is challenging in both diseases.

Objectives: We sought a serum biomarker that could identify patients with SSc-ILD or IPF and prospectively predict short-term decline in lung function in these patients.

Empyema thoracis from an inhaled peanut.

A 77-year-old man with a history of pulmonary sarcoidosis was referred with persistent cough and reduced air entry on auscultation of the right lung base. He was an ex-smoker with a 40-pack-year history and his general practitioner was concerned about the possibility of bronchogenic carcinoma. A chest radiograph showed a right-sided pleural effusion with right mid-zone airspace opacification.

Holy Saturday asthma.

A 61-year-old man complained of cough and dyspnoea after exposure to colophony-containing solder fumes at work. A histamine challenge test confirmed airway hyper-responsiveness, and colophony-challenge demonstrated a 16.7% drop in peak expiratory flow rate (PEFR), supporting a diagnosis of colophony-induced occupational asthma.

Rare causes of persistent wheeze that mimic poorly controlled asthma.

Upper airway obstruction can present with stridor or expiratory or inspiratory wheeze and is commonly misdiagnosed as asthma. As asthma is common, such cases can remain hidden among patients with lower airway obstruction who attend primary care or respiratory clinics. We describe four causes of upper airway obstruction (paradoxical vocal cord movement, subglottic stenosis, retrosternal goitre and double aortic arch) which were misdiagnosed as 'poorly controlled asthma'.

A case series of patients on chemotherapy with dyspnoea and pulmonary infiltrates.

Clinicians often assume that patients who develop pulmonary symptoms and radiographic infiltrates while receiving cytotoxic chemotherapy have opportunistic pulmonary infection or chemotherapy-related interstitial lung disease. We describe two cases of rare complications of commonly used chemotherapeutic agents (gemcitabine-induced eosinophilic pneumonia and rituximab-induced hypersensitivity pneumonitis) that vindicate this assumption but a third case of scleroderma-associated interstitial lung disease that became clinically manifest in a patient who was receiving chemotherapy. The latter case highlights the need for vigilance for other causes of interstitial lung disease in patients receiving chemotherapy.

Sorafenib-induced tuberculosis reactivation.

Background: Sorafenib is a multikinase inhibitor with an established role in treating renal cell carcinoma and hepatocellular carcinoma. In vivo studies have demonstrated sorafenib's inhibitory effects on various immune cells and cytokines which are essential to the maintenance of latency of granulomas in patients with latent tuberculosis infection.

Case Report: A 74-year-old male with clear cell renal cell carcinoma with pulmonary metastases was treated with sorafenib to good effect.

Effects of budesonide and formoterol on allergen-induced airway responses, inflammation, and airway remodeling in asthma.

Background: Combining inhaled corticosteroids with long-acting beta(2)-agonists results in improved asthma symptom control and fewer asthma exacerbations compared with those seen after inhaled corticosteroids alone. However, there are limited data as to whether these beneficial effects are due to enhanced anti-inflammatory actions or whether such combination therapies affect airway remodeling in patients with asthma.

Objective: We sought to determine the effects of inhaled budesonide/formoterol combination therapy versus inhaled budesonide alone or inhaled placebo on allergen-induced airway responses, airway inflammation, and airway remodeling.

Immunosuppressant-responsive idiopathic lymphocytic pleuritis.

Lymphocyte-dominant pleural inflammation is seen in tuberculous, malignant and immune-mediated pleural disease. We describe two male patients who presented with chest pain and dyspnoea, in whom radiological and histological investigations showed idiopathic lymphocytic pleuritis that responded to immunosuppressive therapy with corticosteroids and/or azathioprine. Corticosteroid-responsive pleuritis has been described in association with many conditions, but little is known of idiopathic lymphocytic pleuritis.

The role of substance P in inflammatory disease.

The diffuse neuroendocrine system consists of specialised endocrine cells and peptidergic nerves and is present in all organs of the body. Substance P (SP) is secreted by nerves and inflammatory cells such as macrophages, eosinophils, lymphocytes, and dendritic cells and acts by binding to the neurokinin-1 receptor (NK-1R). SP has proinflammatory effects in immune and epithelial cells and participates in inflammatory diseases of the respiratory, gastrointestinal, and musculoskeletal systems.

Airways obstruction in survivors of thoracoplasty: reversibility is greater in non-smokers.

Objective: Before the advent of antituberculous chemotherapy, thoracoplasty (TPL) was the definitive form of therapy for cavitary pulmonary tuberculosis. This study aimed to characterize the late functional sequelae of TPL, and to establish the degree of reversibility of any consequent airway obstruction.

Methodology: Pulmonary function was studied in 21 long-term (mean 35 years) survivors of TPL between the years 1990-2001.

Upregulation of neurokinin-1 receptor expression in the lungs of patients with sarcoidosis.

Substance P (SP) is a proinflammatory neuropeptide that is secreted by sensory nerves and inflammatory cells. Increased levels of SP are found in sarcoid bronchoalveolar lavage fluid. SP acts by binding to the neurokinin-1 receptor and increases secretion of tumor necrosis factor-alpha in many cell types.
