Which factors are associated with acquired weakness in the ICU? An overview of systematic reviews and meta-analyses.

Rationale: Intensive care unit-acquired weakness (ICUAW) is common in critically ill patients, characterized by muscle weakness and physical function loss. Determining risk factors for ICUAW poses challenges due to variations in assessment methods and limited generalizability of results from specific populations, the existing literature on these risk factors lacks a clear and comprehensive synthesis.

Objective: This overview aimed to synthesize risk factors for ICUAW, categorizing its modifiable and nonmodifiable factors.

Epidemiology of supplemental oxygen in patients with pulmonary hypertension.

Background And Objective: Patients with pulmonary hypertension (PH) may present with hypoxaemia at rest or during daily activities. There is no epidemiological data on the prescription of long-term oxygen therapy (LTOT) in patients with PH. The study sought to analyse the prevalence and incidence of LTOT prescription among patients with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) in Spain and to determine predictors for this prescription.

Pulmonary vascular disease in chronic lung diseases: cause or comorbidity?

Purpose Of Review: To provide timely and relevant insights into the complex relationship between pulmonary vascular disease (PVD) and chronic lung disease (CLD), focusing on the causative and consequential dynamics between these conditions.

Recent Findings: There are shared pathogenic mechanisms between pulmonary arterial hypertension (PAH) and group 3 pulmonary hypertension, including altered expression of mediators and growth factors implicated in both conditions. Factors such as hypoxia, hypoxemia, and hypercapnia also contribute to pulmonary vascular remodelling and endothelial dysfunction.

Which Sit-to-Stand Test Best Differentiates Functional Capacity in Older People?

The sit-to-stand test provides insight into age-related functional capacity; however, there are various variants of sit-to-stand, and we do not know which of these better discriminates against age-related functional capacity. Our study aimed to compare the age-related functional capacity in older people by evaluating sit-to-stand power variants, using young individuals as a reference. A cross-sectional study was conducted in 102 adults (57 women) aged 60-80 and 105 adults (54 women) aged 20-30.

Virtual assessment and management of chronic cough: A scoping review.

Background: Chronic cough is a frequent reason for seeking consultation with primary care providers. The recent widespread adoption of virtual care offers a promising alternative that can be used to optimize the assessment and management of this condition. The objective of this review was to map and identify the strategies used to assess and/or manage chronic cough virtually, and to explore their impact on cough severity and patient satisfaction with virtual care.

Only half of the authors of overviews of exercise-related interventions use some strategy to manage overlapping primary studies-a metaresearch study.

Objectives: The conduct of systematic reviews (SRs) and overviews share several similarities. However, because the unit of analysis for overviews is the SRs, there are some unique challenges. One of the most critical issues to manage when conducting an overview is the overlap of data across the primary studies included in the SRs.

Six-minute walking distance and desaturation-distance ratio in allogeneic stem cell transplantation.

Background: Most patients with haematological malignancies who undergo allogeneic haematopoietic stem cell transplant (HSCT) receive chemotherapy before the transplant to control the disease. Certain chemotherapy drugs can cause lung toxicity. Conversely, in patients with chronic respiratory conditions, the 6-min walking test (6MWT) and the desaturation-distance ratio (DDR) have demonstrated prognostic significance.

Inspiratory muscle training in patients with obesity: a systematic review and meta-analysis.

Introduction: Obesity is a chronic medical condition that affects, among others, the cardiovascular and respiratory systems. Interventions for its treatment focus on sustained weight reduction and general health improvement, leaving respiratory management aside. Our objective was to determine the effects of inspiratory muscle training (IMT) in patients with obesity.

Interrater Reliability of the Spanish (Colombia) Version of the Post-COVID-19 Functional Status Scale.

Background: COVID-19 has been one of the most critical public health challenges of recent decades. This disease develops severely in one in five patients, and approximately 5% require admission to a critical care unit. Due to the impact of the sequelae, the Post-COVID-19 Functional Status Scale (PCFS) was developed.

Pulmonary rehabilitation in sarcoidosis: A systematic review and meta-analysis.

Background: Exercise intolerance, muscle weakness, dyspnoea, and fatigue are frequent complications in symptomatic sarcoidosis patients. Pulmonary rehabilitation improves exercise capacity, symptoms, and quality of life in patients with chronic respiratory diseases. Our objective was to systematically determine the effects of pulmonary rehabilitation in patients with sarcoidosis.

Maximal Respiratory Pressure Reference Equations in Healthy Adults and Cut-off Points for Defining Respiratory Muscle Weakness.

Introduction: Maximal inspiratory and expiratory pressures (PImax/PEmax) reference equations obtained in healthy people are needed to correctly interpret respiratory muscle strength. Currently, no clear cut-off points defining respiratory muscle weakness are available. We aimed to establish sex-specific reference equations for PImax/PEmax in a large sample of healthy adults and to objectively determine cut-off points for respiratory muscle weakness.

Management of Pulmonary Hypertension Associated with Chronic Lung Disease.

Pulmonary hypertension (PH) is a common complication of chronic lung diseases, particularly in chronic obstructive pulmonary disease (COPD) and interstitial lung diseases (ILD) and especially in advanced disease. It is associated with greater mortality and worse clinical course. Given the high prevalence of some respiratory disorders and because lung parenchymal abnormalities might be present in other PH groups, the appropriate diagnosis of PH associated with respiratory disease represents a clinical challenge.

Exploring long COVID condition in Latin America: Its impact on patients' activities and associated healthcare use.

Background: Studies exploring long COVID condition (LCC) in low- and middle-income countries are scarce. Further characterization of LCC patients experiencing activity limitations and their associated healthcare use is needed. This study aimed to describe LCC patients' characteristics, its impact on activities, and associated healthcare use in Latin America (LATAM).

Effects on Sleep Quality of Physical Exercise Programs in Older Adults: A Systematic Review and Meta-Analysis.

Background: Given the beneficial effects of exercise in different populations and the close relationship between healthy ageing and sleep quality, our objective was to determine if physical exercise delivered through a structured program improves sleep quality in older adults.

Methods: Embase, PubMed/MEDLINE, Web of Science, and Cochrane Register of Clinical Trials (CENTRAL) were searched to 15 January 2023. Studies that applied physical exercise programs in older adults were reviewed.

Strategies used to manage overlap of primary study data by exercise-related overviews: protocol for a systematic methodological review.

Introduction: One of the most conflicting methodological issues when conducting an overview is the overlap of primary studies across systematic reviews (SRs). Overlap in the pooled effect estimates across SRs may lead to overly precise effect estimates in the overview. SRs that focus on exercise-related interventions are often included in overviews aimed at grouping and determining the effectiveness of various interventions for managing specific health conditions.
