Five years of advances in electrochemical analysis of protein biomarkers in lung cancer: a systematic review.

Lung cancer is the leading cause of cancer death in both men and women. It represents a public health problem that must be addressed through the early detection of specific biomarkers and effective treatment. To address this critical issue, it is imperative to implement effective methodologies for specific biomarker detection of lung cancer in real clinical samples. Electrochemical methods, including microfluidic devices and biosensors, can obtain robust results that reduce time, cost, and assay complexity. This comprehensive review will explore specific studies, methodologies, and detection limits and contribute to the depth of the discussion, making it a valuable resource for researchers and clinicians interested in lung cancer diagnosis.

Determinants of medical prescriptions for COPD care: an analysis of the EPOCONSUL clinical audit.

Purpose: Current COPD management recommendations indicate that pharmacological treatment can be stepped up or down, but there are no recommendations on how to make this adjustment. We aimed to describe pharmacological prescriptions during a routine clinical visit for COPD and study the determinants of changing therapy. Methods: EPOCONSUL is a Spanish nationwide observational cross-sectional clinical audit with prospective case recruitment including 4,508 COPD patients from outpatient respiratory clinics for a period of 12 months (May 2014-May 2015). Prescription patterns were examined in 4,448 cases and changes analyzed in stepwise backward, binomial, multivariate, logistic regression models. Results: Patterns of prescription of inhaled therapy groups were no treatment prescribed, 124 (2.8%) cases; one or two long-acting bronchodilators (LABDs) alone, 1,502 (34.6%) cases; LABD with inhaled corticosteroids (ICSs), 389 (8.6%) cases; and triple therapy cases, 2,428 (53.9%) cases. Incorrect prescriptions of inhaled therapies were observed in 261 (5.9%) cases. After the clinical visit was audited, 3,494 (77.5%) cases did not modify their therapeutic prescription, 307 (6.8%) cases had a step up, 238 (5.3%) cases had a change for a similar scheme, 182 (4.1%) cases had a step down, and 227 (5.1%) cases had other nonspecified change. Stepping-up strategies were associated with clinical presentation (chronic bronchitis, asthma-like symptoms, and exacerbations), a positive bronchodilator test, and specific inhaled medication groups. Stepping down was associated with lung function impairment, ICS containing regimens, and nonexacerbator phenotype. Conclusion: The EPOCONSUL study shows a comprehensive evaluation of pharmacological treatments in COPD care, highlighting strengths and weaknesses, to help us understand how physicians use available drugs.

Management of COPD in End-of-Life Care by Spanish Pulmonologists.

Chronic obstructive pulmonary disease is progressive and in its advanced stage is associated with major disability. Previous studies suggest that patients with this disease receive little palliative care, even in very advanced stages. Given this, our objectives were to describe the clinical practice of Spanish pulmonologists in the care of patients with end-stage chronic obstructive pulmonary disease, to identify potential barriers to implementing palliative care in these patients and to correlate these responses with doctor's years of experience. A link to an online survey was sent to pulmonologists on (a) symptom management, (b) structure of their department and collaboration with other services, (c) specialized medical training in palliative care, (d) communication with patients and their families, and (e) limiting barriers identified in the management of these patients. A total of 387 responses were received. The majority used opioids to treat dyspnea (52.9%) or pain (54.2%) and many treated anxiety/depression (41%). Around half of the respondents had no established routines in their departments to offer palliative care to patients with chronic obstructive pulmonary disease. There was little communication with end-of-life patients and their families on disease course, mainly associated with a lack of medical training (83% of cases) and changes in patient wishes regarding care through the disease course (81%). In our setting, communication with end-of-life patients with chronic obstructive pulmonary disease is poor. The key challenges identified are insufficient medical training and changing desires of patients. No substantial differences in attitude were found as a function of experience.

Effect of inhaled corticosteroids on salival composition: a cross-sectional study in patients with bronchial asthma.

BACKGROUND: To date, no evidence exists in the literature as to the effects of inhaled corticosteroids (ICs) on salivary composition in patients with bronchial asthma. OBJECTIVE: The aim of this study was to assess the effect of ICs on salival composition. METHODS: Adult patients attending an outpatient respiratory clinic who were classified into two groups (controls and patients with bronchial asthma receiving ICs), were recruited in this cross-sectional study. For each participant, data of clinical records, baseline history of asthma, and regular IC dose were recorded. A sample of stimulated saliva was collected and processed for investigation of mucin 5B (MUC5B), lipoxygenase (LPO), total antioxidant capacity, and 8-hydroxydeoxyguanosine (8-OHdG) levels. RESULTS: Overall, 103 patients (49 controls and 54 patients receiving regular treatment with ICs) were recruited. No differences in comorbidities or smoking habits were observed. Patients treated with high-doses of ICs showed lower levels of salival MUC5B compared with those treated with medium IC doses or those not treated with ICs (1.60 vs. 2.20 vs. 2.53 ng/mL; p = 0.042). CONCLUSION: In patients with asthma, treatment with high-doses of ICs is associated with reduced levels of salivary MUC5B. This effect can explain some of the effects of ICs on oral health.
