Ageing and COPD affect different domains of nutritional status: the ECCE study

2010

Chronic obstructive pulmonary disease (COPD) and ageing may contribute to malnutrition. We aimed to explore whether COPD and ageing determine malnutrition in different manners. 460 stable COPD outpatients (376 males and 84 females) from the Extrapulmonary Consequences of COPD in the Elderly (ECCE) study database were investigated (age 75.0±5.9 yrs; forced expiratory volume in 1 s 54.7±18.3% predicted). Nutritional status was evaluated using the Mini Nutritional Assessment® (MNA) questionnaire. From the MNA, three scores exploring the domains of the nutritional status were calculated: body composition, energy intake and body functionality scores.

Association between reduced bronchodilatory effect of deep inspiration and loss of alveolar attachments.

2005

Abstract Background We have previously shown that the bronchodilatory effect of deep inspiration is attenuated in individuals with COPD. This study was designed to investigate whether the impairment in this effect is associated with loss of alveolar attachments. Methods We measured deep inspiration (DI)-induced bronchodilation in 15 individuals with and without COPD (67 ± 2.2 yrs of age, mean ± SEM) undergoing lobar resection for peripheral pulmonary nodule. Prior to surgery, we measured TLCO and determined the bronchodilatory effect of deep inspiration after constricting the airways with methacholine. The number of destroyed alveolar attachments, as well as airway wall area and airway smoo…

Sex differences in obstructive sleep apnoea.

2019

Obstructive sleep apnoea (OSA) and obstructive sleep apnoea/hypopnoea syndrome (OSAHS) have long been considered predominantly male-related conditions. The clinical presentation of sleep disordered breathing in females differs from males and can vary with age and physiological status,e.g.menopause and pregnancy. Overall, females appear to be more symptomatic, with lower apnoea–hypopnoea index scores compared to males. Furthermore, they appear to have more prolonged partial upper airway obstruction, and may report insomnia as a symptom of OSAHS more frequently. As a consequence of these differences in clinical presentation, females with sleep disordered breathing are often underdiagnosed and…

Sleep HERMES: a European training project for respiratory sleep medicine

2011

The clinical characterisation and description of the obstructive sleep apnoea/hypopnoea syndrome (OSAHS) and related syndromes have been revealed by several epidemiological studies conducted in the late 20th and 21st centuries. These highly prevalent syndromes affect about 9% of middle-aged males and 4% of females. These syndromes have serious medical and social consequences, such as cardiovascular or metabolic diseases and even premature death. Consequently, respiratory sleep medicine has evolved and progressed rapidly within the sleep medicine field over the last decades. New diagnostic and therapeutic techniques appeared in response to an increasing number of patients and clinical interv…

Tracheostomy in patients with long-term mechanical ventilation: a survey.

2010

Summary Background Tracheostomy is increasingly performed in intensive care units (ICU), with many patients transferred to respiratory ICU (RICU). Indications/timing for closing tracheostomy are discussed. Aim and Method We report results of a one-year survey evaluating: 1) clinical characteristics, types of tracheostomy, complications in patients admitted to Italian RICU in 2006; 2) clinical criteria and systems for performing decannulation, and outcome of patients undergoing tracheostomy (number decannulated; number non-decannulated/non-ventilated; number non-decannulated/ventilated; dead/lost patients). Results 22/32 RICUs replied. There were 846 admissions of 719 patients (Mean age 64,3…

Introducing a core curriculum for respiratory sleep practitioners

2015

Abstract: The background and purpose of the HERMES (Harmonising Education in Respiratory Medicine for European Specialists) initiative has been discussed at length in previous articles [1–3]. This article aims to provide more detailed and specific insight into the process and methodology of the Sleep HERMES Task Force in developing a core curriculum in respiratory sleep medicine.

Bronchial responsiveness and airway inflammation in trained subjects [9]

The Importance of Phenotyping Bronchiectasis.

2016

Bronchiectasis is considered to be one of the most heterogeneous respiratory diseases due to both multiple etiological conditions and variable clinical manifestations. This huge heterogeneity is one of the main reasons for disease complexity, and thus, there is a need to identify clinical phenotypes which have specific therapeutic and follow-up indications as in other respiratory diseases [i.e. chronic obstructive pulmonary disease (COPD) or asthma]. Unfortunately, identifying phenotypes of bronchiectasis is not an easy task, and so far, attempts to link aetiology to clinical severity have failed.

Clinical implications of airway hyper-responsiveness in COPD

2006

COPD represents one of the leading causes of mortality in the general population. This study aimed at evaluating the relationship between airway hyperresponsiveness (AHR) and COPD and its relevance for clinical practice. We performed a MEDLINE search that yielded a total of 1919 articles. Eligible studies were defined as articles that addressed specific aspects of AHR in COPD, such as prevalence, pathogenesis, or prognosis. AHR appears to be present in at least one out of two individuals with COPD. The occurrence of AHR in COPD is influenced by multiple mechanisms, among which impairment of factors that oppose airway narrowing plays an important role. The main determinants of AHR are reduct…

An Official American Thoracic Society Workshop Report: Evaluation and Management of Asthma in the Elderly.

2016

Asthma in the elderly (>65 yr old) is common and associated with higher morbidity and mortality than asthma in younger patients. The poor outcomes in this group are due, in part, to underdiagnosis and undertreatment. There are a variety of factors related to aging itself that affect the presentation of asthma in the elderly and influence diagnosis and management. Structural changes in the aging lung superimposed on structural changes due to asthma itself can worsen the disease and physiologic function. Changes in the aging immune system influence the cellular composition and function in asthmatic airways. These processes and differences from younger individuals with asthma are not well u…
