Rebranding of Predatory Journals and Conferences: Understanding Its Implication and Prevention Strategy.

Academic conference participation and publications serve as a litmus test to evaluate researchers irrespective of their scientific discipline. Predatory or fake conferences and journals exploit this issue and rebrand themselves through multiple methods. This paper serves to introduce rebranding as one of the features adopted by predatory journals and conferences and formulate some important measures that could be taken by academic libraries, researchers, and publishers to address this issue.

Thoracic Kyphosis on Chest CT Scans Is Associated With Incident Vertebral Fractures in Smokers.

Greater kyphosis angles lead to increased loading on vertebral bodies in computational models. However, results about the relationship between severity of kyphosis and incident vertebral fracture (VF) risk have been conflicting. Therefore, the aim of this study was to evaluate associations between 1) prevalent VFs and severity of kyphosis, and 2) severity of kyphosis and incident VF risk in smokers with or without chronic obstructive pulmonary disease (COPD).

High Imminent Vertebral Fracture Risk in Subjects With COPD With a Prevalent or Incident Vertebral Fracture.

Subjects with chronic obstructive pulmonary disease (COPD) have an increased risk of vertebral fractures (VFs); however, VF incidence is largely unknown. Therefore, the aim of our study was to determine the incidence of new and/or worsening VF in subjects with COPD. Smokers and subjects with COPD (GOLD II-IV) from the ECLIPSE study with complete set of chest CT scans (baseline and 1- and 3-year follow-up) to evaluate vertebrae T down to L were included.

Physical activity patterns and clusters in 1001 patients with COPD.

We described physical activity measures and hourly patterns in patients with chronic obstructive pulmonary disease (COPD) after stratification for generic and COPD-specific characteristics and, based on multiple physical activity measures, we identified clusters of patients. In total, 1001 patients with COPD (65% men; age, 67 years; forced expiratory volume in the first second [FEV], 49% predicted) were studied cross-sectionally. Demographics, anthropometrics, lung function and clinical data were assessed.

Perioperative respiratory care in obese patients undergoing bariatric surgery: Implications for clinical practice.

Obesity is an increasing problem worldwide. The number of people with obesity doubled since the 1980's to affect an estimated 671 million people worldwide. Obese patients in general have an altered respiratory physiology and can have an impaired lung function, which leads to an increased risk of developing pulmonary complications during anaesthesia and after bariatric surgery (approximately 8%).

Comparative analysis of respiratory muscle strength before and after bariatric surgery using 5 different predictive equations.

Study Objective: Obesity has detrimental effects on general health and respiratory function. This study aimed to evaluate respiratory muscle strength in the morbidly obese population, before and after bariatric surgery, and to compare these estimates with the predictive values using different mathematical equations available.

Design: Prospective cohort study.

Preoperative exercise therapy in lung surgery patients: A systematic review.

Objectives: The impact of postoperative complications after lung surgery for cancer is substantial, with the increasing age of patients and the presence of comorbidities. This systematic review summarises the effects of Preoperative Exercise Therapy (PET) in patients scheduled for lung surgery on aerobic capacity, physical fitness, postoperative complications, length of hospital stay, quality of life and recovery.

Methods: A systematic search on PET prior to lung surgery was conducted.

Effects of bariatric surgery on inspiratory muscle strength.

Background: The respiratory function is affected by obesity due to an increased deposition of fat on the chest wall. The objective of this study was to investigate the strength of the inspiratory respiratory muscles of obese individuals and the possible influence of bariatric surgery on it by measuring the maximum inspiratory pressure (MIP).

Methods: Patients referred to a bariatric centre between the 3rd of October 2011 and the 3rd of May 2012 were screened preoperatively by a multidisciplinary team.

Identifying Physical Activity Profiles in COPD Patients Using Topic Models.

With the growing amount of physical activity (PA) measures, the need for methods and algorithms that automatically analyze and interpret unannotated data increases. In this paper, PA is seen as a combination of multimodal constructs that can cooccur in different ways and proportions during the day. The design of a methodology able to integrate and analyze them is discussed, and its operation is illustrated by applying it to a dataset comprising data from COPD patients and healthy subjects acquired in daily life.

Fracture prevention in COPD patients; a clinical 5-step approach.

Although osteoporosis and its related fractures are common in patients with COPD, patients at high risk of fracture are poorly identified, and consequently, undertreated. Since there are no fracture prevention guidelines available that focus on COPD patients, we developed a clinical approach to improve the identification and treatment of COPD patients at high risk of fracture. We organised a round-table discussion with 8 clinical experts in the field of COPD and fracture prevention in the Netherlands in December 2013.

Six-minute walk distance in patients with chronic obstructive pulmonary disease: Which reference equations should we use?

The use of different 6-min walk distance (6MWD) reference equations probably results in different predicted 6MWD reference values. We wished to investigate the impact of several 6MWD reference equations for adults in patients with chronic obstructive pulmonary disease (COPD) and factors accountable for different 6MWD% predicted values. Twenty-two 6MWD reference equations were applied to a data set of 2757 patients with COPD.

Should I stay or should I go home? A latent class analysis of a discrete choice experiment on hospital-at-home.

Objectives: This study aimed 1) to quantify the strength of patient preferences for different aspects of early assisted discharge in The Netherlands for patients who were admitted with a chronic obstructive pulmonary disease exacerbation and 2) to illustrate the benefits of latent class modeling of discrete choice data. This technique is rarely used in health economics.

Methods: Respondents made multiple choices between hospital treatment as usual (7 days) and two combinations of hospital admission (3 days) followed by treatment at home.

Characteristics and determinants of endurance cycle ergometry and six-minute walk distance in patients with COPD.

Background: Exercise tolerance can be assessed by the cycle endurance test (CET) and six-minute walk test (6MWT) in patients with Chronic Obstructive Pulmonary Disease (COPD). We sought to investigate the characteristics of functional exercise performance and determinants of the CET and 6MWT in a large clinical cohort of COPD patients.

Methods: A dataset of 2053 COPD patients (43% female, age: 66.

Informal caregiver strain, preference and satisfaction in hospital-at-home and usual hospital care for COPD exacerbations: results of a randomised controlled trial.

Background: Informal caregivers play an important role in hospital-at-home schemes. However they may increase their burden, especially chronic diseases, like COPD. In the absence of clear differences in effectiveness and cost-effectiveness between hospital-at-home and usual hospital care, informal caregiver preferences play an important role.

Associations between COPD related manifestations: a cross-sectional study.

Background: Cardiovascular disease, osteoporosis and emphysema are associated with COPD. Associations between these factors and whether they predict all-cause mortality in COPD patients are not well understood. Therefore, we examined associations between markers of cardiovascular disease (coronary artery calcification [CAC], thoracic aortic calcification [TAC] and arterial stiffness), bone density (bone attenuation of the thoracic vertebrae), emphysema (PI-950 and 15th percentile) and all-cause mortality in a COPD cohort.

Osteoporosis in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is being regarded as a heterogeneous disease with clinically significant pulmonary and extrapulmonary manifestations, such as emphysema, cardiovascular disease and osteoporosis. Osteoporosis is characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to enhanced bone fragility and, consequently, an increased risk of fracture. Fractures resulting from osteoporosis might contribute to increased morbidity and mortality, particularly in COPD patients.

Cost-effectiveness of early assisted discharge for COPD exacerbations in The Netherlands.

Objectives: Hospital admissions for exacerbations of chronic obstructive pulmonary disease are the main cost drivers of the disease. An alternative is to treat suitable patients at home instead of in the hospital. This article reports on the cost-effectiveness and cost-utility of early assisted discharge in The Netherlands.

Patient preference and satisfaction in hospital-at-home and usual hospital care for COPD exacerbations: results of a randomised controlled trial.

Background: In the absence of clear differences in effectiveness and cost-effectiveness between hospital-at-home schemes and usual hospital care, patient preference plays an important role. This study investigates patient preference for treatment place, associated factors and patient satisfaction with a community-based hospital-at-home scheme for COPD exacerbations.

Methods: The study is part of a larger randomised controlled trial.

Bone stiffness and failure load are related with clinical parameters in men with chronic obstructive pulmonary disease.

Osteoporosis is frequently seen in patients with chronic obstructive pulmonary disease (COPD). Because research on bone structure and bone strength in COPD patients is limited, the objectives of this pilot study were as follows: (1) to compare bone structure, stiffness, and failure load, measured at the peripheral skeleton, between men with and without COPD after stratification for areal bone mineral density (aBMD); and (2) to relate clinical parameters with bone stiffness and failure load in men with COPD. We included 30 men with COPD (normal aBMD, n = 18; osteoporosis, n = 12) and 17 men without COPD (normal aBMD, n = 9; osteoporosis, n = 8).

CT-measured bone attenuation in patients with chronic obstructive pulmonary disease: relation to clinical features and outcomes.

Osteoporosis is highly prevalent in chronic obstructive pulmonary disease (COPD) patients and has been related to several clinical features. However, most studies have been in relatively small COPD cohorts. Therefore, the objectives of this study were to compare bone attenuation measured on low-dose chest computed tomography (CT) between COPD subjects and smoker and nonsmoker controls, and to relate bone attenuation to clinical parameters, inflammatory biomarkers, and outcomes in a large, well-characterized COPD cohort.

Early assisted discharge with generic community nursing for chronic obstructive pulmonary disease exacerbations: results of a randomised controlled trial.

Objectives: To determine the effectiveness of early assisted discharge for chronic obstructive pulmonary disease (COPD) exacerbations, with home care provided by generic community nurses, compared with usual hospital care.

Design: Prospective, randomised controlled and multicentre trial with 3-month follow-up.

Setting: Five hospitals and three home care organisations in the Netherlands.

Care delivery pathways for Chronic Obstructive Pulmonary Disease in England and the Netherlands: a comparative study.

Introduction: A remarkable difference in care delivery pathways for Chronic Obstructive Pulmonary Disease (COPD) is the presence of hospital-at-home for COPD exacerbations in England and its absence in the Netherlands. The objective of this paper is to explain this difference.

Methods: Descriptive COPD statistics and care delivery pathways on all care levels within the institutional context, followed by a comparison of care delivery pathways and an explanation of the difference with regard to hospital-at-home.

Bone attenuation on routine chest CT correlates with bone mineral density on DXA in patients with COPD.

Chronic obstructive pulmonary disease (COPD), although primarily a disease of the lungs, is associated with extrapulmonary effects such as muscle weakness and osteoporosis. Fractures owing to osteoporosis cause significant morbidity and mortality, particularly in patients with COPD. To prevent osteoporotic fractures, it is important to diagnose osteoporosis in an early stage and to start anti-osteoporotic therapy in at-risk patients.

Vitamin D status is associated with bone mineral density and functional exercise capacity in patients with chronic obstructive pulmonary disease.

Background: Chronic obstructive pulmonary disease (COPD) is associated with several extrapulmonary effects that contribute to the severity of the disease. Vitamin D is suggested to play a role in COPD and its related extrapulmonary effects.

Aims: To determine the prevalence of vitamin D deficiency and its relation with bone density, muscle strength, and exercise capacity in patients with COPD.
