Non-pharmacological Management in Palliative Care for Patients With Advanced COPD

Pulmonary rehabilitation: A cohort study assessing the effectiveness of a multi-professional nutrition intervention

BACKGROUND

Limited benefit of pulmonary exercise rehabilitation has been associated with fulfilment of energy and protein requirements.

OBJECTIVES

The aim was to enhance dietary intake towards requirements and to maintain changes after a pulmonary rehabilitation program.

METHODS

This single arm intervention study included multidisciplinary focus on nutrition and three sessions of individual dietary counselling during a 10-week pulmonary exercise rehabilitation in five municipalities centers. Data were collected at baseline (P0), at the end of intervention (P1) and for two municipalities at three months post intervention (P2).

RESULTS

Of the 111 included participants, (mean age 70.8 (±9)) 99 (89%) completed the rehabilitation including the three individual dietary counselling's. A very large variation in body composition including body mass index and exercise abilities was found. Protein intake improved from 64 (±22 g) (P0) to 88 (±25 g) (P1) (p < 0.001) and energy intake from 1676 (±505 kcal) (P0) to 1941 (±553 kcal) (p < 0.001) (P1) and Muscle Mass Index increased from 10.6 (±3.2) (P0) to 10.9 (±3.2) (P1) (p = 0.007); number of 30 s chair stand test improved from 10.9 (±2.8) repetitions (P0) to 14.1 (±4.3) repetitions (P1) (p < 0.001), distance in six-minut walking test improved from 377.2 (±131.2 m) (P0) to 404.1 (±128.6 m) (P1) (p < 0.001). Two municipalities completed the three months follow-up. For those, dietary improvements remained stable, including protein intake.

CONCLUSION

Including three sessions of dietary counselling in a multi-professional effort was associated with improved individualized dietary intake, as well as physical function. Benefits remained almost unchanged after three months. Improvements in function could not be fully explained by improved intakes.

Exploring the Prevalence of Respiratory Failure in Adults Presenting With Acute Exacerbations of Chronic Obstructive Pulmonary Disease

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) poses a significant global health burden and is a leading cause of morbidity and mortality. Acute exacerbations of COPD often lead to respiratory failure, necessitating a thorough understanding of its prevalence. This study aimed to investigate the prevalence of respiratory failure among adult patients experiencing acute exacerbations of COPD.

MATERIALS AND METHODS

A descriptive, cross-sectional study was conducted over a span of seven months at the internal medicine department of Hayatabad Medical Complex, Peshawar. A total of 255 adult patients with acute exacerbations of COPD were included, and their demographic data, as well as arterial blood gas (ABG) analysis results, were collected. The prevalence of respiratory failure was defined by specific arterial blood gas criteria.

RESULTS

The study revealed a notable prevalence of respiratory failure (41.18%) among COPD patients presenting with acute exacerbations. Factors such as older age and male gender were identified as being associated with a heightened risk of respiratory failure.

CONCLUSION

In conclusion, acute exacerbations of COPD predominantly affect middle-aged males (65.5%), with the 51-60 age group being the most impacted. Respiratory failure was present in over 41% of cases. ABG analysis indicated significant acid-base imbalances, hypoxemia, and hypercapnia, with compensatory chronic respiratory acidosis. These findings highlight the need for targeted interventions to manage and prevent COPD exacerbations, especially in middle-aged men.

Management of Refractory Chronic Obstructive Pulmonary Disease: A Review

Chronic obstructive pulmonary disease (COPD) is a common condition with an estimated prevalence of 12% in adults over the age of 30 years worldwide. COPD is a leading cause of morbidity and mortality globally, with a substantial economic and social burden. There are an estimated 3 million deaths annually due to COPD. However, most of the patients with COPD respond to routine interventions like bronchodilator therapy, assessing supplemental oxygen needs, smoking cessation, vaccinations, and pulmonary rehabilitation. There is a significant number of patients who unfortunately progress to have persistent symptoms despite these interventions. Refractory COPD is not yet formally defined. Patients with severe persistent symptoms or exacerbations despite appropriate care can be considered to have refractory COPD. Managing refractory COPD needs a multidimensional approach. In this review article, we will discuss essential interventions like ensuring adequate inhaler techniques, exploring the need for non-invasive ventilatory support, use of chronic antibiotics and phosphodiesterase inhibitors to advanced therapies like bronchoscopic lung volume reduction surgery, and the upcoming role of anti-IL5 agents in managing patients with refractory COPD. We will also discuss non-pharmacologic interventions like psycho-social support and nutritional support. We will conclude by discussing the palliative care aspect of managing patients with refractory COPD. Through this review article, we aim to better the approach to managing patients with refractory COPD and discuss new upcoming therapies.

Bridging knowledge gaps: a bibliometric analysis of non-invasive ventilation in palliative care studies

BACKGROUND

Despite being a useful strategy for providing respiratory support to patients with advanced or terminal illnesses, non-invasive ventilation (NIV) requires in-depth investigation in several key aspects.

OBJECTIVES

This bibliometric analysis seeks to comprehensively examine the existing research on the subject. Its goal is to uncover valuable insights that can inform the prediction trajectory of studies, guide the implementation of corrective measures, and contribute to the improvement of research networks.

METHODS

A comprehensive review of literature on NIV in the context of palliative care was conducted using the Web of Science core collection online database. The search utilized the key terms "non-invasive ventilation" and "palliative care" to identify the most relevant articles. All data were gathered on November 7, 2023. Relevant information from documents meeting the specified criteria was extracted, and Journal Citation Reports™ 2022 (Clarivate Analytics) served as the data source. The analysis employed literature analysis and knowledge visualization tools, specifically CiteScope (version 6.2.R4) and VOSviewer (version 1.6.20).

RESULTS

A dataset with bibliometric findings from 192 items was analyzed. We found a consistent upward of the scientific output trend over time. Guidelines on amyotrophic lateral sclerosis management received the highest number of citations. Most documents were published in top-ranked journals. Less than one-third of the documents pertain to clinical studies, especially retrospective analyses (25%). Key topics such as "decision making", and "communication" were less addressed.

CONCLUSIONS

Given the substantial clinical implications, further high-quality studies on this subject are recommended. Encouraging international collaborations is needed. Despite the growing volume of documents in the field, this bibliometric analysis indicates a decline in collaborative networks.
