Associations of medicine use and ejection fraction with the coexistence of frailty and sarcopenia in a sample of heart failure outpatients: a cross-sectional study.

BACKGROUND: Frailty and sarcopenia have been extensively studied in heart failure (HF) patients, but their coexistence is unknown. The aim of this work is to describe the coexistence of these conditions in a sample of HF outpatients and its association with the use of medication and left-ventricular ejection fraction. METHODS: Participants in this cross-sectional study were recruited from a HF outpatients' clinic in northern Portugal. Frailty phenotype was assessed according to Fried et al. Sarcopenia was evaluated according to the revised consensus of the European Working Group on Sarcopenia in Older People. RESULTS: A total of 136 HF outpatients (33.8% women, median age 59 years) integrated this study. Frailty and sarcopenia accounted for 15.4% and 18.4% of the sample, respectively. Coexistence of frailty and sarcopenia was found in 8.1% of the participants, while 17.6% had only one of the conditions. In multivariable analysis (n = 132), increasing age (OR = 1.13;95%CI = 1.06,1.20), being a woman (OR = 65.65;95%CI = 13.50, 319.15), having heart failure with preserved ejection fraction (HFpEF) (OR = 5.61; 95%CI = 1.22, 25.76), and using antidepressants (OR = 11.05; 95%CI = 2.50, 48.82), anticoagulants (OR = 6.11; 95%CI = 1.69, 22.07), furosemide (OR = 3.95; 95%CI = 1.07, 14.55), and acetylsalicylic acid (OR = 5.01; 95%CI = 1.10, 22.90) were associated with increased likelihood of having coexistence of frailty and sarcopenia, while using statins showed the inverse effect (OR = 0.06; 95%CI = 0.01, 0.30). CONCLUSIONS: The relatively low frequency of coexistence of frailty and sarcopenia signifies that each of these two conditions still deserve individual attention from health professionals in their clinical practice and should be screened separately. Being a woman, older age, having HFpEF, using anticoagulants, antidepressants, loop diuretics and acetylsalicylic acid, and not using statins, were associated with having concomitant frailty and sarcopenia. These patients can potentially benefit from interventions that impact their quality of life such as nutritional and mental health interventions and exercise training.

Socioeconomic Inequalities and Predictors of Cardiac Rehabilitation Referral: Real-World Evidence.

OBJECTIVE: The aim of the study is to identify factors associated with cardiac rehabilitation referral after an acute coronary syndrome at a university hospital. DESIGN: We analyzed 2814 hospitalizations due to acute coronary syndrome between 2017 and 2019 in Centro Hospitalar São João. The hospital's morbidity database was used to retrieve patient information. Cardiac rehabilitation referral and participation were identified from administrative databases and clinical records. Socioeconomic data were obtained from municipality of residence-level data rather than patient-specific data. RESULTS: Of 2814 hospitalizations, 72% (2028 cases) were eligible for cardiac rehabilitation. Mean age was 65.2 ± 13.4 yrs; 72% men, 33% diabetic, 57.1% hypertensive, and 63.6% dyslipidemic. Cardiac rehabilitation referral rate was low, at 18.8%, with 42 (11.0%) not attending cardiac rehabilitation and 39 (10.2%) dropping out. Females (odds ratio = 0.72 [95% confidence interval = 0.52-1.00]), older patients (odds ratio = 0.57 [0.42-0.77]; 55-64 vs. <55 yrs), and those coming from lower-income municipalities (odds ratio = 0.53 [0.41-0.69], below median vs. above median) with lower education level (odds ratio = 0.70 [0.54-0.92]; ≤4 vs. >4 yrs) were less likely to be referred to cardiac rehabilitation. CONCLUSIONS: There is a need for new strategies to promote cardiac rehabilitation in disadvantaged groups, as sex, age, and socioeconomic inequities in access to cardiac rehabilitation remain unresolved.

Statins are associated with reduced likelihood of sarcopenia in a sample of heart failure outpatients: a cross-sectional study.

BACKGROUND: Sarcopenia is prevalent in heart failure (HF) patients, contributing to its poor prognosis. Statin use is postulated as a probable risk for developing sarcopenia, but little is known regarding this association in HF patients. This work aims at classifying and characterising sarcopenia and at describing the association of statin use with sarcopenia in a sample of Portuguese HF outpatients. METHODS: In this cross-sectional study, a sample of 136 HF patients (median age: 59 years, 33.8% women) was recruited from an HF outpatients' clinic of a University Hospital in Portugal. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People 2. Clinical, nutritional, and dietary data were collected. RESULTS: A total of 25 (18.4%) individuals were categorised as sarcopenic, ranging from 12.2% in younger (< 65 years) participants vs. 30.4% in older ones and from 3.3% in men vs. 47.8% in women. Severe sarcopenia accounted for 7.4% of the sample and sarcopenic obesity was identified in 5.1% of the individuals. A total of 65.4% of the participants were statin users. In multivariable analysis (n = 132, 25 sarcopenic), the use of statins was inversely associated with sarcopenia (OR = 0.03; 95% CI = 0.01, 0.30). Each additional age year was associated with a 9% increase in the likelihood of being sarcopenic (OR = 1.09; 95% CI = 1.01, 1.17), and each Kg.m-2 increment in body mass index was associated with a 21% decrease in the likelihood of sarcopenia (OR = 0.79; 95% CI = 0.65, 0.96). The daily use of five or more medicines was also directly associated with sarcopenia (OR = 26.87; 95% CI = 2.01, 359.26). On the other hand, being a man and being physically active were inversely associated with sarcopenia (OR = 0.01; 95% CI = 0.00, 0.07 and OR = 0.09; 95% CI = 0.01, 0.65, respectively). CONCLUSIONS: Contrary to what was expected, patients medicated with statins were less likely to be sarcopenic. Although this finding deserves further research, we hypothesise that this might be related to the pleiotropic effects of statins on endothelial function, contributing to better neuromuscular fitness.

Time-trends and predictors of interhospital transfers and 30-day rehospitalizations after acute coronary syndrome from 2000-2015.

AIMS: Assess trends and factors associated with interhospital transfers (IHT) and 30-day acute coronary syndrome (ACS) rehospitalizations in a national administrative database of patients admitted with an ACS between 2000-2015. METHODS AND RESULTS: Cohort study of patients hospitalized with ACS from 2000 to 2015, using a validated linkage algorithm to identify and link patient-level sequential hospitalizations occurring within 30 days from first admission (considering all hospitalizations within the 30-day timeframe as belonging to the same ACS episode of care-ACS-EC). From 212,481 ACS-EC, 42,670 (20.1%) had more than one hospitalization. ACS-EC hospitalization rates decreased throughout the study period (2000: 207.7/100.000 person-years to 2015: 185,8/100,000 person-years, p for trend <0.05). Proportion of IHT increased from 10.5% in 2000 to 20.1% in 2015 compared to a reduction in both planned and unplanned 30-day ACS rehospitalization from 9.0% in 2000 to 2.7% in 2015. After adjusting for patient and first admission hospital's characteristics, compared to 2000-2003, in 2012-2015 the odds of IHT increased by 3.81 (95%CI: 3.65-3.98); the odds of unplanned and planned 30-day ACS rehospitalization decreased by 0.36 (95%CI: 0.33; 0.39) and 0.47 (95%CI: 0.43; 0.53), respectively. Female sex, older age and the presence and severity of comorbidities were associated with lower likelihood of being transferred or having a planned 30-day ACS rehospitalization. Unplanned 30-day ACS rehospitalization was more likely in patients with higher comorbidity burden. CONCLUSION: IHT and 30-day ACS rehospitalization reflect coronary referral network efficiency and access to specialized treatment. Identifying factors associated with higher likelihood of IHT and 30-day ACS rehospitalization may allow heightened surveillance and interventions to reduce rehospitalizations and inequities in access to specialized treatment.

Frailty phenotype and associated nutritional factors in a sample of Portuguese outpatients with heart failure.

BACKGROUND AND AIM: Frailty phenotype (FP) is very common in heart failure (HF) and both syndromes worsen one another. The aim of this study is to first describe FP in a sample of Portuguese patients with HF, and to analyse its association with nutritional and clinical statuses, namely, muscle mass, obesity and functional class. METHODS AND RESULTS: In this cross-sectional study, a sample of 136 outpatients with HF (24-81 years, 33.8% women) were randomly selected from the appointments' listings of a HF and Transplant clinic in a Portuguese University Hospital. FP was assessed according to Fried et al. muscle mass was estimated from the mid-upper arm muscle circumference; weight status was assessed using the body mass index; HF functional classes were registered. The association between participants' characteristics and FP categories was analysed using logistic ordinal regression. The frequency of pre-frailty and frailty is 57.4% and 15.4%, respectively. Within frail individuals, 52.4% were under the age of 65. In multivariable analysis, frailty was positively associated with age 70 or older (OR = 3.44) and obesity (OR = 2.66), and negatively associated with muscle mass (OR = 0.77) and HF functional classes I (OR = 0.14) or II (OR = 0.29). CONCLUSION: Muscle mass seems to be an important predictor of frailty in patients with HF and should be taken into account when designing intervention plans that allow for reverting or modifying frailty and pre-frailty. Younger patients should be monitored for the presence and evolution of FP.

Clinical ABCDE rule for early melanoma detection.

BACKGROUND: The ABCDE rule systematizes warning signs for malignant melanoma (MM). OBJECTIVES: To evaluate whether the ABCDE signs are associated with early detection of MM. MATERIALS & METHODS: Based on a retrospective study over 11.5 years, we assessed whether ABCDE signs are associated with early diagnosis of MM. RESULTS: In total, 144 MM were included; 52 (36.1%) in situ and 92 (63.9%) invasive lesions. For 23.6%, the MM were first suspected by an individual other than a dermatologist. The "E sign" was significantly less frequent among in situ lesions (32.7% versus 50.0%; p = 0.044). Based on adjusted analyses, the probability of MM being first suspected by a non-dermatologist consistently increased with the number of ABCDE signs of the lesion, ranging from 8% for a neoplasm with no ABCDE signs to 32% for a lesion with five signs (OR = 1.6; 95% CI: 1.2-2.2; p = 0.004). CONCLUSION: A higher number of ABCDE signs were associated with a greater chance of MM being first suspected by a non-dermatologist, but not in situ MM diagnosis. Relying on the ABCDE rule alone might result in missing early MM lesions.

Pain as a risk factor for suicidal behavior in older adults: A systematic review.

OBJECTIVE: The objective of this systematic review was to examine whether pain is a risk factor for suicidal behavior (suicide ideation, suicide attempts or suicide) in older adults. MATERIAL AND METHODS: An extensive search was conducted on the following databases: MEDLINE, ISI Web of Knowledge, Scopus and PsycARTICLES. Search terms used were "pain", "suicid*" and "elderly". Studies that assessed the relation between pain and suicidal behavior among people aged ≥60 years were included. Two reviewers independently screened the abstracts and applied selection criteria in the full-text of all included articles. RESULTS: Results from 38 original research articles were included and reviewed. Moderate/severe pain increased the risk of suicide ideation from OR = 1.13 (95 %CI = 1.02-1.25) to OR = 2.7 (95 %CI = 1.1-7.0). The influence in suicide attempts ranged between OR = 1.92 (95 %CI 1.17-3.15) and 3.63-fold for extreme pain; and one article reported that the risk of a successful suicide was 4.07-fold higher in pain suffering patients. In most studies, this relation was maintained, even after controlling for other risk factors. Arthritis, back/neck problems and headaches were associated with higher risks of suicidal behavior. Pain was also a stronger predictor for suicide in men (OR = 9.9; 95 %CI = 6.0-16.4) than in women (OR = 3.3; 95 %CI = 1.4-7.7). CONCLUSION: Our results suggest the existence of a relationship between pain and suicidal behavior in older adults. This information may be extremely relevant to inform suicide prevention strategies.

Diagnostic performance of optical coherence tomography angiography in glaucoma: a systematic review and meta-analysis.

BACKGROUND: Compared with current imaging methods, the diagnostic performance and the advantages and limitations of optical coherence tomography angiography (OCTA) remain unclear. We performed a systematic review and meta-analysis of studies investigating vessel density (VD) in patients with glaucoma using OCTA. METHODS: We conducted a literature search on PubMed, Scopus, Web of Science, ISI Conference Proceedings and Google Scholar, along with a manual search, from January 2006 to March 2018. We included prospective studies that used OCTA to compare the VD in glaucomatous eyes with healthy control eyes. RESULTS: Of 3045 screened articles, 24 were included in a broad characterisation and 18 in the meta-analysis. We observed a statistically significant reduction in the mean peripapillary VD (MPVD) in glaucoma (MPVD: 57.53%, 95% CI 52.60 to 62.46, p< 0.001) compared with controls (MPVD: 65.47%, 95% CI 59.82 to 71.11; standardised mean difference [SMD], -1.41, 95% CI -1.62 to -1.20, p< 0.001) for 888 glaucomatous and 475 healthy eyes, and also in the mean-whole optic nerve image VD (SMD, -9.63, 95% CI -10.22 to -9.03, p<0.001), mean inside-disc VD (SMD, - 9.51, 95% CI -12.66 to -6.36, p<0.05) and mean parafoveal VD (SMD, -3.92, 95% CI -4.73 to -3.12, p<0.001). Subgroup analyses revealed a significant difference in the MPVD across glaucoma subtypes and OCTA devices. CONCLUSION: This suggests the diagnostic utility of OCTA in detecting glaucomatous eyes; however, further longitudinal prospective studies are welcomed to characterise vascular changes in glaucoma.

Effectiveness of Opioids for Chronic Noncancer Pain: A Two-Year Multicenter, Prospective Cohort Study With Propensity Score Matching.

Opioid use in chronic non cancer pain (CNCP) is still controversial regarding their effectiveness and safety. We conducted a 2-year prospective cohort study in 4 multidisciplinary chronic pain clinics to assess long-term opioid effectiveness in CNCP patients. All adult CNCP patients consecutively admitted to their first consultation were recruited. Demographic and clinical data were collected, and propensity score matching was used to adjust for differences between opioid users and nonusers. The Brief Pain Inventory and the Short version of Treatment Outcomes in Pain Survey were used to measure pain outcomes and quality of life. A total of 529 subjects were matched and included in our analysis. Rate of prescription opioid use was 59.7% at baseline, which increased to 70.3% over 2 years, of which 42.7% of the prescriptions were for strong opioids. Opioid users reported no improvement regarding pain symptoms, physical function, emotional function, and social/familiar disability. Opioid users reported higher satisfaction with care and outcomes at 1 year of follow-up, but at 2 years, they only reported improvement in satisfaction with outcomes. Opioids have shown limited effectiveness in long-term CNCP management, as opioid users presented no improvements regarding functional outcomes and quality of life. These findings emphasize the need for proper selection and outcome assessment of CNCP patients prescribed opioids. PERSPECTIVE: This study adds important additional evidence concerning the controversial use of opioids in CNCP management. Opioid users presented no improvement regarding pain relief, functional outcomes and quality of life over 2 years of follow-up. Therefore, our results support and highlight the limited effectiveness of opioids in long-term CNCP management.

A [Glyco]biomarker that Predicts Failure to Standard Therapy in Ulcerative Colitis Patients.

BACKGROUND AND AIMS: There is a clinical need to identify biomarkers able to select patients who are most likely to develop aggressive/complicated disease, for early selection for appropriate therapy. Changes in the glycosylation profile of intestinal lymphocytic infiltrate were previously demonstrated to regulate T cell activity, being associated with disease severity in ulcerative colitis [UC] patients. We interrogated whether this heterogeneous expression of branched N-glycans in intestinal inflammatory infiltrate predicts therapy response early in disease course. METHODS: The expression levels of the branched N-glycans in colonic biopsies collected around time of diagnosis from a well-characterised cohort of 131 UC patients were correlated with response to standard therapy. Receiver operating characteristic analysis and specificity/sensitivity were determined. RESULTS: Branched N-glycans levels around time of diagnosis predict non-response to conventional therapy with 75% specificity. Moreover, high levels of branched N-glycans predict 78% of UC patients who will display a favourable disease course [exclusively under 5-aminosalicylate therapy for more than 5 years of disease]. The best predictive performance was observed in severe UC patients with Mayo endoscopic subscore 3 and in those that were naïve to therapy. Multivariable analysis revealed that low levels of branched N-glycans and high levels of C-reactive protein [CRP] around time of diagnosis act as independent predictors of non-response to standard therapy. A powerful effect of the combined use of the branched N-glycans and CRP was observed. CONCLUSIONS: Our results reveal a potential [glyco]biomarker that predicts, early in the disease course, patients who will fail to respond to standard therapy, benefiting thereby from other therapeutic strategies such as biologics.

A Two-Year Prospective Multicenter Study of Opioid Therapy for Chronic Noncancer Pain: Prescription Trends and Predictors.

OBJECTIVES: Opioid use in chronic pain has increased worldwide in recent years. The aims of this study were to describe the trends and patterns of opioid therapy over two years of follow-up in a cohort of chronic noncancer pain (CNCP) patients and to assess predictors of long-term opioid use and clinical outcomes. METHODS: A prospective cohort study with two years of follow-up was undertaken in four multidisciplinary chronic pain clinics. Demographic data, pain characteristics, and opioid prescriptions were recorded at baseline, three, six, 12, and 24 months. RESULTS: Six hundred seventy-four CNCP patients were recruited. The prevalence of opioid prescriptions at baseline was 59.6% (N = 402), and 13% (N = 86) were strong opioid prescriptions. At 24 months, opioid prescription prevalence was as high as 74.3% (N = 501), and strong opioid prescription was 31% (N = 207). Most opioid users (71%, N = 479) maintained their prescription during the two years of follow-up. Our opioid discontinuation was very low (1%, N = 5). Opioid users reported higher severity and interference pain scores, both at baseline and after two years of follow-up. Opioid use was independently associated with continuous pain, pain location in the lower limbs, and higher pain interference scores. CONCLUSIONS: This study describes a pattern of increasing opioid prescription in chronic pain patients. Despite the limited improvement of clinical outcomes, most patients keep their long-term opioid prescriptions. Our results underscore the need for changes in clinical practice and further research into the effectiveness and safety of chronic opioid therapy for CNPC.

Incidence and Health Related Quality of Life of Opioid-Induced Constipation in Chronic Noncancer Pain Patients: A Prospective Multicentre Cohort Study.

BACKGROUND: High rates of opioid use for chronic noncancer pain (CNCP) have been reported worldwide, despite its association with adverse events, inappropriate use, and limited analgesic effect. Opioid-induced constipation (OIC) is the most prevalent and disabling adverse effect associated with opioid therapy. Our aim was to assess the incidence, health related quality of life (HRQOL), and disability in OIC patients. METHODS: A prospective cohort study was performed, with 6 months of follow-up, of adult CNCP patients consecutively admitted in 4 multidisciplinary pain clinics (MPC). Demographic and clinical data have been collected. Brief Pain Inventory (BPI) and Short version of Treatment Outcomes in Pain Survey (S-TOPS) were used to measure functional outcomes and HRQOL. OIC was assessed using Bowel Function Index (BFI). RESULTS: 694 patients were recruited. OIC prevalence at baseline was 25.8%. At 6 months, OIC incidence was 24.8%. Female gender (OR = 1.65, p = 0.039), opioid therapy (OR 1.65, p = 0.026), and interference pain score on BPI (OR 1.10, p = 0.009) were identified as OIC independent predictors. OIC patients presented higher disability and pain interference and severity scores. OIC patients reported less satisfaction with outcome (p = 0.038). DISCUSSION: Constipation is a common adverse event among opioid users with major functional and quality of life impairment. These findings emphasise the need of OIC adequate assessment and management.

Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) System for Outcome Prediction in Elderly Patients Undergoing Major Vascular Surgery.

OBJECTIVE: POSSUM system is widely used and validated for 30-day mortality and morbidity prediction. The aim of this study was to evaluate the performance of five POSSUM's equations (POSSUM, P-POSSUM, V-POSSUM, V-POSSUM physiology and V-POSSUM Cambridge) on predicting 30-day mortality and morbidity in elderly patients undergoing major elective vascular surgery. DESIGN: A retrospective longitudinal cohort study. SETTING: A study conducted at an University Hospital. PARTICIPANTS: 208 elderly patients (≥ 60 years) undergoing major elective vascular surgery. MEASUREMENTS: Data collected from the clinical files included patient's characteristics, diagnosis, surgery, comorbidities, parameters from POSSUM score, 30, 60 and 90-day mortality and 30-day morbidity. POSSUM system's goodness-of-fit for predicting mortality and morbidity was assessed by Hosmer-Lemeshow test (H-L T) and Standardized Mortality/Morbidity Ratio (SMR) and discriminative ability by the area under the ROC curves (ROC-AUC). Patients' average age was 70.8 years, 81% males. INTERVENTIONS: None. MAIN RESULTS: The overall 30-day mortality rate was 2.97% (n=6) and 30-day morbidity was 29.2% (n=59). POSSUM, P-POSSUM, V-POSSUM, V-POSSUM physiology and V-POSSUM Cambridge equation predicted an overall of 29.1, 4.43, 15.3, 21.9 and 13.5 deaths, respectively. POSSUM morbidity equation predicted 105.0 complications. H-LT p-values were 0.001, 0.164, 0.208, 0.011, 0.331 and <0.001, respectively. SMRs and 95% confidence interval (CI) were 0.21[0.04-0.37], 1.35[0.27-2.44], 0.39[0.08-0.71], 0.27[0.06-0.49], 0.44[0.09-0.80] and 0.56[0.42-0.71], respectively. ROC-AUC and 95% CI were 0.72[0.49-0.95], 0.72[0.49-0.95], 0.73[0.51-0.94], 0.69[0.50-0.89], 0.72[0.52-0.92] and 0.71[0.63-0.79], respectively. CONCLUSIONS: P-POSSUM had the best performance predicting 30-day mortality. All the other overestimated 30-day mortality. Prediction of morbidity was inadequate. POSSUM scoring models may not be robust tools for risk prediction in elderly patients undergoing major elective vascular surgery and need further calibration and discrimination.

Cost of asthma in children: A nationwide, population-based, cost-of-illness study.

BACKGROUND: Childhood asthma is very prevalent and costs can be high, especially in severe disease. This study aimed to estimate the cost of asthma in Portuguese children and the variations by level of asthma control. METHODS: A nationwide, population- and prevalence-based cost-of-illness study with a societal perspective was conducted. We measured direct and indirect costs using a bottom-up approach and a human capital method, respectively, for 208 children (<18 years), from two national repositories. Generalized linear modelling for analysis of asthma costs' determinants and sensitivity analysis to assess uncertainty were performed. RESULTS: The mean annualized asthma cost per child was €929.35 (95% CI, 809.65-1061.11): €698.65 (95% CI, 600.88-798.27) for direct costs and €230.70 (95% CI, 197.36-263.81) for indirect costs. Extrapolations for the Portuguese children amounted to €161 410 007.61 (95% CI, 140 620 769.55-184 293 968.55) for total costs. Direct costs represent 75.2% with the costliest domain (51.1% of total costs) being the healthcare service use: 20.7% for scheduled medical visits and 30.4% for acute asthma care-non-scheduled medical visits (7.9%, €12 766 203.20), emergency department visits (11.7%, €18 932 464.80) and hospitalizations (10.8%, €17 406 946.00). Children with partly controlled and uncontrolled asthma had higher mean costs per year (adjusted coefficients: 1.46 [95% CI, 1.12-1.90] and 2.25 [95% CI, 1.56-3.24], respectively). CONCLUSIONS: Costs of childhood asthma are high (0.9% of the healthcare expenditures in Portugal). Direct costs represented three-fourth of total costs, mainly related to the use of healthcare services for acute asthma care. Policies and interventions to improve asthma control and reduce acute use of healthcare services have the potential to reduce asthma costs.

The Portuguese long version of the Copenhagen Psychosocial Questionnaire II (COPSOQ II) - a validation study.

BACKGROUND: Psychosocial risks are now widely recognised as one of the biggest challenges for occupational safety and health (OSH) and a major public health concern. The aim of this paper is to investigate the Portuguese long version of the Copenhagen Psychosocial Questionnaire II (COPSOQ II), in order to analyse the psychometric properties of the instrument and to validate it. METHODS: The Portuguese COPSOQ II was issued to a total of 745 Portuguese employees from both private and public organisations across several economic sectors at a baseline and then 2 weeks later. Methodological quality appraisal was based on COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) recommendations. An analysis of the psychometric properties of the long version of COPSOQ II (internal consistency, intraclass correlation coefficient, floor and ceiling effects, response rate, missing values, mean and standard deviation, exploratory factor analysis) was performed to determine the validity and reliability of the instrument. RESULTS: The COPSOQ II had a response rate of 60.6% (test) and a follow-up response rate of 59.5% (retest). In general, a Cronbach's alpha of the COPSOQ scales (test and retest) was above the conventional threshold of 0.70. The test-retest reliability estimated by the intraclass correlation coefficient (ICC) showed a higher reliability for most of the scales, above the conventional 0.7, except for eight scales. The proportion of the missing values was less than 1.3%, except for two scales. The average scores and standard deviations showed similar results to the original Danish study, except for eight scales. All of the scales had low floor and ceiling effects, with one exception. Overall, the exploratory factor analysis presented good results in 27 scales assuming a reflective measurement model. The hypothesized factor structure under a reflective model was not supported in 14 scales and for some but not all of these scales the explanation may be a formative measurement model. CONCLUSION: The Portuguese long version of COPSOQ II is a reliable and valid instrument for assessing psychosocial risks in the workplace. Although the results are good for most of the scales, there are those that should be evaluated in greater depth in future studies. This instrument may contribute to the promotion of a healthy working environment and workforce, providing clear benefits for companies and employees.

Physical activity and exercise for erectile dysfunction: systematic review and meta-analysis.

BACKGROUND: A growing body of evidence suggests that physical activity and exercise may improve erectile function. OBJECTIVE: To conduct a systematic review and meta-analysis evaluating the effects of physical activity modalities and exercise on erectile function in erectile dysfunction trials. METHODS: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. We searched 6 electronic databases between January 1990 and July 2016 and hand-searched reference lists for randomised controlled trials. Only patients with a diagnosis of erectile dysfunction were included. The mean differences between intervention and control groups were calculated for meta-analysis. RESULTS: 7 studies were eligible, including 478 participants allocated to aerobic, pelvic or combined exercise interventions. Follow-up ranged from 8 weeks to 2 years. The risk of bias in the trials was deemed moderate to high mainly due to impossible blinding of patients and personnel, as well as questionable blinding of outcome assessors. Random-effects meta-analyses were performed. Pooled data showed a statistically significant improvement in erectile function score (mean difference 3.85, 95% CI 2.33 to 5.37). A benefit was still demonstrable after a sensitivity analysis because the mean difference in International Index of Erectile Function (IIEF) score ranged from 3.39 (95% CI 1.92 to 4.87) to 4.28 (95% CI 2.54 to 6.02). A benefit was also detected in short-term and long-term interventions as well as in trials evaluating physical activity and exercise alone or in addition to usual care. CONCLUSIONS: The present study suggests that physical activity and exercise interventions improve patient-reported erectile dysfunction, particularly aerobic exercise with moderate-to-vigorous intensity.

A population-based nationwide cross-sectional study on preventive health services utilization in Portugal--what services (and frequencies) are deemed necessary by patients?

BACKGROUND: Most of the strategies to induce a more rational use of preventive health services are oriented to the medical side of the doctor-patient relationship. However, the consultation model has changed, and patients now have a more important role in medical consultation. The aim of this study was to assess which healthcare services are deemed necessary, and with what frequency, by adults from the general Portuguese population. DESIGN: Population-based nationwide cross-sectional study Setting: Portuguese population Participants: One thousand Portuguese adults, surveyed by computer-assisted telephone interviewing and selected by a stratified cluster sampling design. MEASUREMENTS: Proportions and population prevalence estimates were determined for each healthcare service, taking into account whether respondents considered them necessary, and with what frequency. RESULTS: Respondent ages ranged between 18 and 97 years, and 520 of 1000 (52%) respondents were women. Among Portuguese adults, 99.2% (95% confidence interval (CI): 98.5 to 99.6) believe that they should undergo general routine blood and urine tests, to be repeated every 12.0 months on average (95% CI: 11.4 to 12.6); 87.4% (95% CI: 85.3 to 89.3) of the respondents reported having actually performed these tests. Of the 15 services surveyed, 14 were considered periodically necessary by more than 60% of respondents. Among the respondents, 37.7% (95% CI: 34.5 to 41.1) reported using healthcare services by their own initiative. CONCLUSIONS: The majority of Portuguese adults believe that they should utilize a great number of healthcare services, on a nearly annual basis; most actually follow this schedule. Our findings indicate a tendency towards the overuse of resources. Adequate patient-oriented strategies regarding the use of medical tests and preventive interventions--with appropriate information and discussion of risks and harms--are urgently needed, and crucial for achieving a more rational use of healthcare services and for preventing the consequences of over-testing.

Control of Allergic Rhinitis and Asthma Test (CARAT) can be used to assess individual patients over time.

BACKGROUND: The Control of Allergic Rhinitis and Asthma Test (CARAT10) has been proposed as the first tool to implement the Allergic Rhinitis and its Impact on Asthma initiative guidelines in clinical practice. To serve this purpose, it must have adequate properties to assess the control of an individual over time. This study aimed to prospectively assess the test-retest reliability, responsiveness and longitudinal validity of CARAT10. METHODS: Adults with asthma and allergic rhinitis were enrolled at 4 outpatient clinics of Portuguese central hospitals. At each of the two visits, 4 to 6 weeks apart, patients filled out CARAT10 and additional questionnaires, followed by a medical evaluation blinded to the questionnaires' answers. RESULTS: From the 62 patients included, 51 patients completely filled out CARAT10 at both visits. The test-retest reliability, computed as an intra-class correlation coefficient, was 0.82. Regarding responsiveness, a significant change (p = 0.002) of CARAT10 score in clinically unstable patients was observed (95%CI -5.08; -1.31) and the Guyatt's responsiveness index was 1.54. As for the longitudinal validity assessment, the correlation coefficients of the changes of CARAT10 scores with those of ACQ5 and symptoms VAS ranged from 0.49 to 0.65, while with the physician assessment of control they ranged from 0.31 to 0.41. CONCLUSION: CARAT10 has good test-retest reliability, responsiveness and longitudinal validity. It can be used to assess control of allergic rhinitis and asthma, both to compare groups in clinical studies and to evaluate individual patients in clinical practice.

Control of allergic rhinitis and asthma test--a formal approach to the development of a measuring tool.

BACKGROUND: The concurrent management of allergic rhinitis and asthma (ARA) has been recommended by Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines. However, a tool capable of assessing simultaneously the control of upper and lower airways diseases is lacking. AIM: To describe the studies conducted to design the control of ARA test (CARAT) questionnaire. METHODS: We performed a literature review to generate a list of potentially important items for the assessment of control of ARA. A formal consensus development process, that used an innovative web-based application, was designed - 111 experts in ARA and 60 patients participated. At the final consensus meeting, 25 primary and secondary care physicians formulated the questions and response options. A qualitative feasibility study (n = 31 patients) was conducted to evaluate the comprehensibility of the questionnaire while testing two different designs. RESULTS: Thirty-four potentially important items were identified. All the steps of the consensus process were completed in 2.5 months. The opinions of experts and patients lead to the formulation of 17 questions. At the feasibility study the instructions and wording problems were corrected and a semi-tabular format was chosen. CONCLUSION: A tool to measure the control of allergic rhinitis and asthma was developed using a comprehensive set of methodological steps ensuring the design quality and the face and content validity. Additional validation studies to assess the psychometric properties of the questionnaire have started.

Validation study of the Camberwell Assessment of Need for the Elderly (CANE) in Portugal.

BACKGROUND: The Camberwell Assessment of Need for the Elderly (CANE) is widely used for multidimensional evaluation of older people with mental health problems. The aim of this study was to evaluate reliability and validity of a Portuguese version of CANE. METHOD: A cross-sectional multicenter study was designed using a convenience sample of elderly mental health services' users. CANE was compared with EASYCare, GHQ12, MMSE, Barthel Index and GDS15 to assess criterion and construct validity. Inter-rater and test-retest reliability were also assessed. RESULTS: 79 patients (76% female), with mean age of 74 (+/- 6.6) years were included. Most patients lived at home with a family caregiver, generally female. Only 32% had no carer. Dementia was the commonest psychiatric diagnosis (61%) and somatic comorbidity was very prevalent (85%). Kappa values (kappa) for inter-rater item reliability ranged from 0.72 to 1.00 (mean values: 0.96 patient, 0.93 carer, 0.90 staff). The intraclass correlation coefficient (ICC) for total scores ranged from 0.95 to 0.98.For test-retest item reliability, the mean kappa value was: 0.80 patient, 0.77 carer, 0.81 staff. ICC for total scores ranged from 0.82 to 0.92. Given the absence of a gold standard, criterion validity was assessed by comparing CANE with EASYCare (rs 0.460; p < or = 0.01), GDS (rs 0.615; p < or = 0.01), GHQ (rs 0.581; p < or = 0.01) and Barthel Index (rs-0.435; p < or = 0.01). Overall, inter-item and item-total correlations for CANE and item comparison with other measures indicated reasonable construct validity. CONCLUSION: The psychometric proprieties of CANE seem to be consistently good, in accordance with other studies. Robust results on ecological, face, content, criterion and construct validity, as well as good reliability, were achieved. This version is a promising tool for research and practical use in Portuguese old age settings.
