Dietary habits in patients with fibromyalgia: a cross-sectional study.

Objectives: To the scarce information on dietary habits in fibromyalgia (FM), it is added that there are no comparative studies with other rheumatic diseases. The objective of this study was to characterise the dietary habits of patients with FM by comparing, for the first time, with healthy controls (HC) and rheumatoid arthritis (RA).

Methods: This cross-sectional, observational study was based on data obtained from the Dietfibrom project for FM and from the IMID Consortium for RA and HC.

Characterization of Burnout Among Spanish Family Physicians Treating Fibromyalgia Patients: The EPIFFAC Study.

Objective: Burnout among physicians has increased, affecting not only doctors but also the quality of patient care. Treating challenging disorders, such as fibromyalgia, may increase the risk of feeling burned out. Health care of fibromyalgia patients is increasingly being assigned to family physicians.

Belief in a Just World and Emotional Intelligence in Subjective Well-Being of Cancer Patients.

The study of coping strategies has provided valuable insights about the process of helping cancer patients adapt to their disease. However, new approaches must be explored to increase the knowledge of this adjustment. In this study, we will analyze the relationship between patients' psychological well-being and quality of life and less well-studied constructs such as the belief in a just world (BJW) and emotional intelligence (EI).

Relationship Between Using Clinical Practice Guidelines for Pain Treatment and Physicians' Training and Attitudes Toward Patients and the Effects on Patient Care.

Aims: To determine the use of clinical practice guidelines (CPGs) for chronic pain (CP) management; analyze the effects of training in pain and the attitudes of physicians toward pain and CP patients on the adherence to these CPGs; and assess the impact of adherence to CPGs on patient care.

Method: This was a cross-sectional study in a sample of physicians involved in CP patient management. Information on the use of CPGs for CP management, their training in pain, and their attitudes toward pain, patients, and patient care was collected.

Factors Influencing Cognitive Impairment in Neuropathic and Musculoskeletal Pain and Fibromyalgia.

Objective: To assess cognitive performance of chronic pain (CP) patients diagnosed with three types of pain-neuropathic pain (NP), musculoskeletal (MSK), and fibromyalgia (FM)-and to analyze the factors influencing cognitive difficulties in each group.

Methods: Two hundred fifty-four CP patients-104 NP, 99 MSK, 51 FM-and 72 pain-free subjects were included in the study. The "Test Your Memory" (TYM) scale was used to assess cognitive performance.

Nationwide cross-sectional study of the impact of chronic pain on an individual's employment: relationship with the family and the social support.

Objectives: To determine the prevalence and the factors related to sick leave and job loss among individuals suffering from chronic pain (CP), and to analyse specifically the effect of family and social support on the individual's employment.

Design: Observational cross-sectional study.

Setting: Data were collected using structured computer-assisted telephone interviews between February and June 2011.

Use and satisfaction with the Healthcare System of the chronic pain patients in Spain: results from a nationwide study.

Objective: To analyze the use of healthcare resources by chronic pain (CP) patients in Spain and their satisfaction with them.

Research Design And Methods: A nationwide, cross-sectional study was carried out on a representative sample of 1957 Spanish adults. A telephone survey was conducted with the aim of analyzing the prevalence of CP, the characteristics and consequences of pain, the use of healthcare resources and patients' satisfaction with them.

A review of chronic pain impact on patients, their social environment and the health care system.

Chronic pain (CP) seriously affects the patient's daily activities and quality of life, but few studies on CP have considered its effects on the patient's social and family environment. In this work, through a review of the literature, we assessed several aspects of how CP influences the patient's daily activities and quality of life, as well as its repercussions in the workplace, and on the family and social environment. Finally, the consequences of pain on the health care system are discussed.

Generalized Estimating Equations (GEE) to handle missing data and time-dependent variables in longitudinal studies: an application to assess the evolution of Health Related Quality of Life in coronary patients.

Objectives: to analyse the evolution of Health Related Quality of Life (HRQL) in coronary patients (CP) and to identify predictive factors influencing this evolution in a situation with missing data and time-dependent variables.

Design: prospective study with repeated measures.

Setting And Participants: a total of 175 CP were included.

Simple generalized estimating equations (GEEs) and weighted generalized estimating equations (WGEEs) in longitudinal studies with dropouts: guidelines and implementation in R.

Missing data are a common problem in clinical and epidemiological research, especially in longitudinal studies. Despite many methodological advances in recent decades, many papers on clinical trials and epidemiological studies do not report using principled statistical methods to accommodate missing data or use ineffective or inappropriate techniques. Two refined techniques are presented here: generalized estimating equations (GEEs) and weighted generalized estimating equations (WGEEs).

Methods and Instruments to Evaluate Cognitive Function in Chronic Pain Patients: A Systematic Review.

Objective: We aimed to systematically review the methods and instruments used to evaluate cognitive function in chronic pain (CP) patients.

Methods: A sensitive search strategy was designed using five databases. Based on the objectives and methodology, we selected cross-sectional studies on adults with chronic non-cancer pain in which cognitive function was assessed using validated instruments.

A nationwide study of chronic pain prevalence in the general spanish population: identifying clinical subgroups through cluster analysis.

Objective: This study aims to assess the prevalence of chronic pain, its characteristics, and its impact on the general Spanish population. Also, to establish chronic pain patient subgroups according to the characteristics of pain and to identify variables specifically associated with each subgroup.

Design: Telephone-based, cross-sectional nationwide study.

The impact of chronic pain: the perspective of patients, relatives, and caregivers.

To assess the impact of chronic pain on the family environment from the patient's, relative's and caregiver's perspective, we undertook cross-sectional study on a representative sample of Spanish adults who suffered pain at least 4 days a week for ≥3 months and on relatives and caregivers of patients that fulfilled these criteria. The characteristics of pain and the perception of its impact on the family environment were assessed, using logistic regression models to reveal the variables associated with the impact of pain on the family. From a total of 1,957 subjects, 325 experienced chronic pain and 34.
