RESUMO

Bariatric surgery is associated with changing food preferences, but it is not known whether these changes differ by type of operation or are associated with weight loss. The current study presents validation results for a new 27-item scale, Bariatric Surgical Alterations in Tolerability, Enjoyment and Cravings in the Diet (BSATED). This scale measured enjoyment, craving, and intolerance changes for nine food and beverage categories common to dietary habits in the Southern California region of the U.S. one year following bariatric surgery in the Bariatric Experience Long Term (BELONG) study. Validation of BSATED was done using exploratory factor analyses, construct validity with other conceptually related survey instruments, and criterion validity using hypothesized differences for operation type and percent total weight loss (%TWL) at 12-18 months after surgery. Participants (n = 999) were 86% female, 41% non-Hispanic White, with a mean age of 43.1 ± 11.3 years and a body mass index (BMI) of 43.4 ± 6.8 kg/m2 at the time of surgery. Participants reported less enjoyment and craving for high-fat meats (62%), grains (54%), candy and other desserts (e.g. candy bars, chocolate, ice cream) (52%), and sweet baked goods (48%) 12 months after surgery. These changes were more common among participants undergoing Roux-en-Y gastric bypass (RYGB) compared to those receiving sleeve gastrectomy (SG). Participants who reported decreased enjoyment and craving for foods and beverages that post-bariatric patients are counseled to reduce or avoid had greater %TWL at 12-18 months following surgery (p < .001 and p = .003 respectively). The foods and beverages in BSATED that post-bariatric patients are counseled to reduce or avoid could be used to understand how changes in enjoyment, craving and tolerability of these foods/beverages contribute to weight loss following surgery.

RESUMO

The aim of this study was to determine the prevalence and incidence of Systemic Lupus Erythematosus (SLE) in Tucumán, Argentina. METHODS: The study included inpatient and outpatient charts from four public hospitals and private practice rheumatology clinics, all of them members of the Tucumán Rheumatology Society. Patients older than 16 years with diagnosis of SLE between January 2005 and December 2012 were included. Prevalence and annual incidence were calculated as the number of cases per 100.000 inhabitants during the period 2005 to 2012. RESULTS: Three hundred fifty-three patients were identified. The mean age at diagnosis was 30.5 ± 11.7 years, 93.5% women, 83% mestizos. Prevalence was 24.3 cases/100.000 inhabitants (CI 95% 22.6-28.8) and age-adjusted (≥16 years) of 34.9 cases/100.000 inhabitants (CI 95% 32.8-41.1). The annual incidence in 2005 was 1.8 cases/100.000 inhabitants (95% CI 1-2.9) and 2012 of 4.2 cases/100.000 inhabitants (95% CI 2.9-5.8). Mortality was 9.1%, with infections being the most frequent cause (14/32). CONCLUSION: The prevalence of SLE in the province of Tucumán was 34.9 cases/100.000 inhabitants.

RESUMO

BACKGROUND/OBJECTIVES: Cirrhosis associated immune dysfunction has been proposed to switch from a pro-inflammatory phenotype in stable cirrhosis to an immunodeficient one in patients with decompensated cirrhosis and acute-on-chronic liver failure. The aim of the present study was to compare serum cytokine levels between healthy patients, stable cirrhosis, and decompensated cirrhotic patients with and without development of acute-on-chronic liver failure (ACLF); and to explore whether any of the measured cytokines is associated with cirrhosis severity and prognosis in ACLF patients. METHODS: Patients were enrolled from October 2013 to May 2014 in two hospitals located in Buenos Aires. Cirrhotic patients with an acute decompensating event were enrolled accordingly to the development of ACLF defined by the CANONIC study group. There were two control groups: healthy subjects (n=14) and stable cirrhotic patients (n=14). Demographic, clinical and biochemical data were obtained. Seventeen cytokines were measured using Bio-Plex Pro Human Cytokine 17-plex Assay. RESULTS: Of the 49 decompensated cirrhotic patients enrolled, 18 (36.7%) developed ACLF. Leukocyte count, MELD score at admission, Clif-SOFA at admission and day 7 were significantly higher in the ACLF group (p=0.046, p<0.001, p<0.001, p<0.001 respectively) as well as short-term mortality (p<0.001) compared to stable and decompensated cirrhotic patients. In comparison with healthy controls, stable cirrhotic and decompensated cirrhotic patients showed increased levels of pro-inflammatory and anti-inflammatory cytokines: IL-6, IL-7, IL-8, IL-10, IL 12, and TNF-α. Decompensated cirrhotic patients with the development of ACLF showed a significant decrease of IL-7, IL-10, IL-12, TNF-α, MCP-1 and IFN-γ, but a sustained response of IL-6 and IL-8. When evaluating cirrhosis severity, IL-6 and IL-8 correlated positively with MELD score, whereas only IL-6 correlated positively with Clif-SOFA score at day 7; IL-2 correlated negatively with Clif-SOFA at admission. In comparison with all scores, leukocyte count showed positive correlation and IFN-γ negative correlation with disease severity. When evaluating survival, only MELD and Clif-SOFA scores had a significant association with mortality. CONCLUSIONS: Pro-inflammatory cytokines and chemo-attractant elements are increased in cirrhosis in comparison with healthy subjects, and display higher values concomitantly with cirrhosis progression. However, in acute-on-chronic liver failure an opposite cytokine pattern that can be resumed as a combination of immune paresis and excessive inflammatory response was observed. Several pro-inflammatory cytokines (IL-2, IL-6, IL-8 and IFN-γ) showed correlation with disease severity; their utility as prognostic biomarkers needs to be further studied.

RESUMO

BACKGROUND AND AIMS: Entecavir (ETV) is effective and safe in patients with chronic hepatitis B in the short term, but its long term efficacy and safety has not been established. MATERIAL AND METHODS: We evaluated HBV DNA clearance, HBeAg/antiHBe and HBsAg/antiHBs seroconversion rates in HBeAg-positive and negative NUC naïve HBV patients treated with ETV for more than 6 months, and predictors of response. RESULTS: A hundred and sixty nine consecutive patients were treated with ETV for a median of 181 weeks. 61% were HBeAg positive, 23% were cirrhotics, and mean HBV-DNA levels were 6,88 ± 1,74 log10 IU/mL. Overall, 156 (92%) patients became HBV DNA undetectable, 92 (88%) HBeAg positive and 64 (98%) HBeAg negative patients. Seventy four (71%) patients cleared HBeAg after a median of 48 weeks of treatment, 23 (14%) patients cleared HBsAg (19 HBeAg positive and 4 HBeAg negative, p 0.025) after a median of 96 weeks of treatment, and 22 (13%) patients developed protective titers of anti-HBs. At the end of the study, 35 (20%) patients had discontinued therapy: 33 HBeAg positive and 2 HBeAg negative; 9 of them (26%) developed virological relapse after a median of 48 weeks of stopping treatment. None of the patients had primary non response and one patient developed breakthrough. Two patients developed HCC, three underwent liver transplantation and 3 deaths were attributable to liver-related events. No serious adverse events were reported. CONCLUSION: Long term ETV treatment showed high virological response rates, and a favorable safety profile for NUC-naive HBeAg-positive and negative patients treated in clinical practice.

RESUMO

BACKGROUND: Analyzing trajectories of weight loss may address how particular groups of patients respond to metabolic and bariatric surgery. OBJECTIVES: The Bariatric Experience Long Term (BELONG) study was designed to use a theoretical model to examine determinants of weight loss and recurrence. SETTING: Large integrated health system in Southern California with 11 surgical practices and 23 surgeons. METHODS: A total of n = 1338 patients who had metabolic and bariatric surgery were surveyed before surgery to measure factors related to median percent total weight loss (%TWL) over 5 years. Longitudinal weight data were available for n = 1024 (76.5% of the sample). Data were analyzed using latent growth mixture models (GMM) to estimate trajectories of weight change separately for gastric sleeve and bypass operations. These trajectories were then described using relevant variables from the baseline survey. RESULTS: For both gastric sleeve (n = 733) and bypass (n = 291) operations, 3 latent trajectories of median %TWL were found corresponding to most, moderate, and least %TWL. Sleeve trajectories were distinguished by body mass index at surgery and geocoded environmental factors. Bypass trajectories varied by self-reported and geocoded environmental factors, comorbidity burden, race, experiential avoidance, and weight control strategies. CONCLUSIONS: Future research should examine the role of the built and perceived environment in surgical weight loss. Bariatric practices should focus less on the presurgical period for predictors of long-term weight loss and begin efforts to monitor real-time patient-reported outcomes to help tailor intervention strategies for patients who either do not lose an expected amount of weight or who begin to experience weight recurrence.

RESUMO

INTRODUCTION. High activity antiretroviral therapy (HAART) has allowed people infected with human immunodeficiency virus (HIV) to live longer. In the course of time, hepatocellular carcinoma (HCC) began to be found in these patients. Investigations have suggested that, as it has been described for other tumors, HIV infection raises the risk of developing HCC. However, convincing evidence is still required. Our aim was to quantify the incidence of HCC in hepatitis C cirrhotic patients with and without human immunodeficiency virus infection in the HAART era. MATERIAL AND METHOds. This prospective cohort study was conducted in hepatitis C cirrhotic patients with and without HIV co-infection, between june 1, 1999 and May 21, 2010. Ultrasound screening for HCC was performed every 6 to 12 months to all the patients until January 15, 2011. Incidence rate and cumulative incidence (Kaplan-Meier) were calculated. RESULTS. One hundred and forty eight patients (69 hepatitis C virus mono-infected and 79 HIV/hepatitis C virus co-infected) were followed for a median time of 43 months, with a total follow-up of 555 person-years (324 for co-infected and 231 for mono-infected patients). Twelve patients developed HCC (5 co-infected and 7 mono-infected). The incidence of HCC in co-infected patients and mono-infected patients was 1.54 (95% confidence interval = 0.5 to 3.6) and 3.03 (95% confidence interval = 1.22 to 6.23) cases per 100 person-year respectively (log-rank p = 0.3225). CONCLUSION. In the HAART era, HIV co-infection is not associated with a higher incidence of HCC in hepatitis C cirrhotic patients.

RESUMO

AIMS: To assess the current situation of the inspection validation of prescriptions (IVP) in Spain since the introduction of the electronic procedure (EP) from the healthcare professionals' perspective. DESIGN: Observational, cross sectional study, in two phases; combining qualitative and quantitative techniques. SETTING: Primary Care (PC), Secondary Care (SC) and the health care management sector. PARTICIPANTS: Primary care physicians (PCPs), endocrinologists, medical inspectors, pharmacists and health Authorities of Autonomous Communities (AACC). METHOD: Semi-structured surveys and Computer Assisted Telephone Interviewing. RESULTS: The IVP presents three modalities in Spain: manual, electronics and electronics linked to electronic prescription. The participants of the same level of management perceive in a similar way the purpose of the IVP, and there exist differences between the different levels of interviewed managers. Differences exist in the situation of EP between AACC. It is more implemented in primary care (PC) than in specialized (63% vs 37%), with similar degree in urban and rural areas. Six of 17 AACC presented a public access to the corresponding legislation. CONCLUSION: The IVP is perceived as a tool for the economic control in expenditure on drugs and as additional administrative load in PC. The rhythm of implementation of EP differs between AACC as well as the access to the regulation.

RESUMO

OBJECTIVE: This study examined the association between individual- and neighborhood-level sociodemographic factors and surgical weight loss at 1 year (short term) and 3 years (long term). METHODS: Data were obtained from the baseline survey of the BELONG (Bariatric Experience Long Term) prospective longitudinal cohort study. Individual-level self-reported data on sex, race and ethnicity, education, and household income were obtained by survey. Data from the 2010 US Census were used to calculate area Neighborhood Deprivation Index score and median value of owner-occupied housing units at the census tract level. RESULTS: Patients (N = 1341) had a mean age of 43.4 (SD 11.3) years, were mostly female (86%), were mostly Black or Hispanic (52%), had some college education (83%), and had annual household incomes ≥$51,000 (55%). Percentage total weight loss was 25.8% (SD 9.0%) at year 1 and 22.2% (SD 10.5%) at year 3. Race and ethnicity and age were significant predictors of weight loss at 1 and 3 years with a small effect of self-reported household income at year 1. There were no significant associations between census tract-level Neighborhood Deprivation Index score or value of owner-occupied housing units and weight loss at either time point. CONCLUSIONS: Health systems could improve the chances of weight-loss maintenance after surgery by addressing factors related to racial and ethnic disparities and to income disparities.

RESUMO

Background: Liver fibrosis is a leading cause of morbimortality in people with HIV/hepatitis C virus (HCV). Natural killer (NK) cells are linked with amelioration of liver fibrosis; however, NK cells from individuals coinfected with HIV/HCV with cirrhosis display impaired functionality and high PD-1 expression. Here, we aimed to study PD-1, TIGIT, and Tim3 as potential exhaustion markers in NK cells from persons coinfected with HIV/HCV with mild and advanced liver fibrosis. We also evaluated the role of PD-1 expression on NK cells after HCV clearance by direct-acting antivirals (DAAs). Methods: Peripheral blood mononuclear cells were isolated from individuals coinfected with HIV/HCV (N = 54; METAVIR F0/F1, n = 27; F4, evaluated by transient elastography, n = 27). In 26 participants, samples were collected before, at the end of, and 12 months after successful DAA treatment. The frequency, immunophenotype (PD-1, TIGIT, and Tim3 expression), and degranulation capacity (CD107a assay) of NK cells were determined by flow cytometry. Results: Unlike PD-1, Tim3 and TIGIT were comparably expressed between persons with mild and advanced fibrosis. Degranulation capacity was diminished in NK/TIGIT+ cells in both fibrosis stages, while NK/PD-1+ cells showed a lower CD107a expression in cirrhotic cases. Twelve months after DAA treatment, those with advanced fibrosis showed an improved NK cell frequency and reduced NK/PD-1+ cell frequency but no changes in CD107a expression. In individuals with mild fibrosis, neither PD-1 nor NK cell frequency was modified, although the percentage of NK/CD107a+ cells was improved at 12 months posttreatment. Conclusions: Although DAA improved exhaustion and frequency of NK cells in cirrhotic cases, functionality was reverted only in mild liver fibrosis, remarking the importance of an early DAA treatment.

RESUMO

PURPOSE: Weight loss surgery is an effective, long-term treatment for severe obesity but individual response to surgery varies widely. The purpose of this study was to test a comprehensive theoretical model of factors that may be correlated with the greatest surgical weight loss at 1-3 years following surgery. Such a model would help determine what predictive factors to measure when patients are preparing for surgery that may ensure the best weight outcomes. MATERIALS AND METHODS: The Bariatric Experience Long Term (BELONG) study collected self-reported and medical record-based baseline information as correlates of 1- and 3-year % total weight loss (TWL) in n = 1341 patients. Multiple linear regression was used to determine the associations between 120 baseline variables and %TWL. RESULTS: Participants were 43.4 ± 11.3 years old, Hispanic or Black (52%; n = 699), women (86%; n = 1149), and partnered (72%; n = 965) and had annual incomes of ≥ $51,000 (60%; n = 803). A total of 1006 (75%) had 3-year follow-up weight. Regression models accounted for 10.1% of the variance in %TWL at 1-year and 13.6% at 3 years. Only bariatric operation accounted for a clinically meaningful difference (~ 5%) in %TWL at 1-year. At 3 years after surgery, only bariatric operation, Black race, and BMI ≥ 50 kg/m2 were associated with clinically meaningful differences in %TWL. CONCLUSIONS: Our findings combined with many others support a move away from extensive screening and selection of patients at the time of surgery to a focus on improving access to this treatment.

RESUMO

Background: Cardiovascular (CV) diseases remain a leading and costly cause of death globally. Patients with previous CV events are at high risk of recurrence. Secondary prevention therapies improve CV risk factor control and reduce disease costs. Objectives: To assess the cost-effectiveness of a CV polypill strategy (CNIC-Polypill) compared with the loose combination of monocomponents to improve the control of CV risk factors in patients with previous coronary heart disease or stroke. Methods: A Markov model cost-utility analysis was developed using 4 health states, SMART risk equation, and 3-month cycles for year 1 and annual cycles thereafter, over a lifetime horizon from the perspective of the National Health System in Portugal (base case). The NEPTUNO study, Portuguese registries, mortality tables, official reports, and the literature were consulted to define effectiveness, epidemiological costs, and utility data. Outcomes were costs (estimated in 2020 euros) per life-year (LY) and quality-adjusted LY (QALY) gained. A 4% discount rate was applied. Alternative scenarios and one-way and probabilistic sensitivity analyses tested the consistency and robustness of results. Results: The CNIC-Polypill strategy in secondary prevention provides more LY and QALY, at a higher cost, than monocomponents. The incremental cost-utility ratio is €1557/QALY gained. Assuming a willingness-to-pay threshold of €30 000/QALY gained, there is a 79.7% and a 44.4% probability of the CNIC-Polypill being cost-effective and cost-saving, respectively, compared with the loose combination of monocomponents. Results remain consistent in the alternative scenarios and robust in the sensitivity analyses. Discussion: The model reflects increments in the number of years patients would live and in quality of life with the CNIC-Polypill. The clinical effectiveness of the CNIC-Polypill strategy initially demonstrated in the NEPTUNO study has been recently corroborated in the SECURE trial. The incremental cost of the CNIC-Polypill strategy emerges slightly above the comparator, but willingness-to-pay estimates and sensitivity analyses indicate that the CNIC-Polypill strategy is consistently cost-effective compared with monocomponents and remains within acceptable affordability margins. Conclusion: The CNIC-Polypill is a cost-effective secondary prevention strategy. In patients with histories of coronary heart disease or stroke, the CNIC-Polypill more effectively controls CV risk factors compared with monocomponents.

RESUMO

OBJECTIVE: This study examined the association of weight loss following bariatric surgery with self-reported sleep quality after accounting for other sleep-related factors. METHODS: Participants were from the Bariatric Experience Long Term (BELONG) study. Participants completed a survey up to 6 months before surgery and approximately 1 year after surgery. The Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality. One-year percentage total weight loss (%TWL) was determined from electronic medical records. Covariates included demographics, Charlson Comorbidity Index, geocoded variables to assess neighborhood quality, and physical activity. The authors assessed the association between %TWL at 1 year and PSQI component scores with separate cumulative logit models. RESULTS: There were 997 participants in the analytic cohort. Participants were 86.2% women, 37.0% Hispanic, and 13.7% Black adults. Mean one-year %TWL was 26.3 (SD 8.7). Each 1% increase in %TWL was associated with a 3% better daytime dysfunction score (odds ratio = 1.03; 95% CI: 1.02-1.05) and a 2% better sleep quality score (odds ratio = 1.02; 95% CI: 1.00-1.03). No significant differences were found for the other PSQI components. CONCLUSIONS: Weight loss from bariatric surgery was associated with better self-reported sleep at 1 year. For people undergoing bariatric surgery, there may be an added benefit of better sleep.

RESUMO

PURPOSE: The Bariatric Experience Long Term (BELONG) prospective study cohort was created to address limitations in the literature regarding the relationship between surgical weight loss and psychosocial, health, behaviour and environmental factors. The BELONG cohort is unique because it contains 70% gastric sleeve and 64% patients with non-white race/ethnicity and was developed with strong stakeholder engagement including patients and providers. PARTICIPANTS: The BELONG cohort study included 1975 patients preparing to have bariatric surgery who completed a baseline survey in a large integrated health system in Southern California. Patients were primarily women (84%), either black or Hispanic (59%), with a body mass index (BMI) of 45.1±7.4 kg/m2, age 43.3±11.5 years old, and 32% had at least one comorbidity. FINDINGS TO DATE: A total of 5552 patients were approached before surgery between February 2016 and May 2017, and 1975 (42%) completed a baseline survey. A total of 1203 (73%) patients completed the year 1 and 1033 (74%) patients completed the year 3 postoperative survey. Of these survey respondents, 1341 at baseline, 999 at year 1, and 951 at year 3 were included in the analyses of all survey and weight outcome data. A total of 803 (60% of eligible patients) had survey data for all time points. Data collected were self-reported constructs to support the proposed theoretical model. Height, weight and BMI were abstracted from the electronic medical record to obtain the main outcomes of the study: weight loss and regain. FUTURE PLANS: We will collect self-reported constructs and obtain height, weight and BMI from the electronic medical record 5 years after bariatric surgery between April 2022 and January 2023. We will also collect patient experiences using focus groups of 8-12 patients each throughout 2022.

RESUMO

OBJECTIVE: To appraise economic evaluations of health technologies that included quality-adjusted life-years (QALYs) as an outcome measure conducted over the past 20 years in Spain. METHODS: A systematic review of the literature was conducted. Economic evaluations that included QALYs as an outcome measure, conducted in Spain and published between January 1990 and December 2009 were identified. Primary and gray literature sources were reviewed. RESULTS: A total of 60 articles and 4 health technology assessment reports were included. Key findings were 1) the vast majority of articles (77.1%) referred to therapeutic interventions; 2) 63.2% dealt with pharmaceutical products and much fewer with preventive strategies, medical devices, or diagnostic interventions; 3) most evaluations referred to cardiovascular- (19.8%), respiratory- (16.3%), and cancer- (13.0%) related processes; 4) 80.3% were based on a theoretical model, most commonly Markov models (71.4%); 5) 67.3% adopted the National Health System perspective; 6) information on the methods used to describe the health states was given in 45.1% of studies; 7) 40.3% used the EuroQoL-5D to elicit preferences, whereas 66.1% gave no details on the methods applied to determine patients' choices; 8) it was possible to state who completed the questionnaires in only 17.7% of studies; 9) 77.1% of the interventions assessed were below the €30,000/QALY suggested affordable threshold in Spain. CONCLUSIONS: An increasing number of economic evaluations using QALYs had been conducted. Most of them relied on theoretical models. Several methodological issues remain unsolved. Great disparity exists regarding the reporting of the methods used to determine health states and utility values.

RESUMO

BACKGROUND: Despite the wide use of the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC) in a clinical setting to assess agitated patients, a validation study to evaluate its psychometric properties was missing. METHODS: Data from the observational NATURA study were used. This research describes trends in the use of treatments in patients with acute psychotic episodes and agitation seen in emergency departments. Exploratory principal component factor analysis was performed. Spearman's correlation and regression analyses (linear regression model) as well as equipercentile linking of Clinical Global Impression of Severity (CGI-S), Agitation and Calmness Evaluation Scale (ACES) and PANSS-EC items were conducted to examine the scale's diagnostic validity. Furthermore, reliability (Cronbach's alpha) and responsiveness were evaluated. RESULTS: Factor analysis resulted in one factor being retained according to eigenvalue ≥1. At admission, the PANSS-EC and CGI-S were found to be linearly related, with an average increase of 3.4 points (p < 0.001) on the PANSS-EC for each additional CGI-S point. The PANSS-EC and ACES were found to be linearly and inversely related, with an average decrease of 5.5 points (p < 0.001) on the PANSS-EC for each additional point. The equipercentile method shows the poor sensitivity of the ACES scale. Cronbach's alpha was 0.86 and effect size was 1.44. CONCLUSIONS: The factorial analyses confirm the unifactorial structure of the PANSS-EC subscale. The PANSS-EC showed a strong linear correlation with rating scales such as CGI-S and ACES. PANSS-EC has also shown an excellent capacity to detect real changes in agitated patients.

RESUMO

PURPOSE: Bariatric surgery is the most effective treatment for severe obesity, but currently, only 1-2% of all eligible patients undergo surgery each year. This study examined which factors were associated with a patient receiving bariatric surgery after referral in a real-world healthcare setting. MATERIALS AND METHODS: The current study used the baseline survey and electronic medical record (EMR) data from the Bariatric Experience Long Term (BELONG) study (n = 1975). Predictors of who did (n = 1680) and who did not (n = 295) have surgery were analyzed using multivariate logistic regression. RESULTS: Participants (n = 1975; 42.4% response rate) were primarily women (84%) and either non-Hispanic Black or Hispanic (60%). In the fully adjusted multivariate model, the strongest predictors of having surgery were being a woman (OR = 3.17; 95% CI = 2.15, 4.68; p < .001) and losing at least 5% of their body weight in the year before surgery (OR = 3.16; 95% CI = 2.28, 4.38; p < .001). The strongest predictors of not having surgery were a ≥ BMI 50 kg/m2 (OR = .39; 95% CI = .27, .56; p < .001) and having a higher physical comorbidity burden (OR = .84; 95% CI = .75, .94; p = .004). CONCLUSIONS: Practices such as 5-10% total weight loss before surgery and selection of patients with safer operative risk profiles (younger with lower comorbidity burden) may inadvertently contribute to under-utilization of bariatric surgery among some demographic subpopulations who could most benefit from this intervention.

RESUMO

BACKGROUND AND AIM: Having decision making capacity is central to the exercise of autonomy in mental health care. The objective of this scoping review is to summarize the evidence on the capacity of people with schizophrenia or bipolar disorder to make decisions about their treatment in real life to support medical practice. METHODS: Systematic search of observational studies on the assessment of capacity of patients with schizophrenia, psychosis, or bipolar disorder to make healthcare and treatment-related decisions, conducted in any clinical setting published up to January 31, 2020 was performed. Free text searches and medical subject headings in English were combined in PubMed, Scopus, CINAHL, and PsycInfo. Publications were selected as per inclusion and exclusion criteria. The Newcastle-Ottawa Scale for observational studies was used to assess the quality of publications. RESULTS: Thirty publications were reviewed. According to the Newcastle-Ottawa Scale criteria, the publications reviewed were good quality. Findings showed that more than 70% of schizophrenia and schizoaffective disorder outpatients understood treatment options at the point of making decisions about their illness and healthcare. Patients treated voluntarily had considerably better scores for decisional capacity than those treated involuntarily. The burden of psychiatric symptoms could compromise decisional capacity temporarily. Decision-making capacity improved over time from admission to discharge from hospital, and with treatment among psychiatry inpatients. Schizophrenia and bipolar disorder patients could be as competent as nonpsychiatric individuals in making decisions about their treatments in everyday life. CONCLUSIONS: This scoping review provides a body of evidence for healthcare professionals in need of assessing the capacity of schizophrenia and bipolar disorder patients for autonomously decide about their treatments. Decisional capacity judgements should consider variations in capacity over time and be based on the type of decision to be made, the severity of symptoms, and the specific phase of the mental disorder.

RESUMO

BACKGROUND: Diabetes and prediabetes are chronic conditions that affect over 40% of the US adult population combined. Regular physical activity can benefit people with diabetes through improved glucose control and can reduce the conversion of prediabetes to diabetes. Studies are needed in settings where people with these conditions can be identified and provided the skills and support to increase physical activity. The primary care setting meets this need, but there are insufficient high-quality trials to recommend this approach be broadly implemented. METHODS: We conducted a randomized, 24-week pilot study in Southern California to assess the feasibility of using information technology systems available in primary care for identifying potential participants, test methods for obtaining physical activity clearance, conducting mail-based assessments, and delivering telephone-based motivational interviewing to increase physical activity. Eligibility criteria included age between 18 and 74 years, diabetes or prediabetes, and physically inactive based on a clinical assessment tool. At baseline and follow-up, physical activity was assessed by a 7-day accelerometry, cardiometabolic risk factors were collected from electronic medical records, and psychosocial factors were assessed from validated questionnaires administered through a mail survey. Participants were block randomized into intervention or usual care. Staff collecting outcome data were blinded to group assignment. Analysis of covariance was used to assess the difference at follow-up between the intervention and usual care, adjusting for baseline. RESULTS: A total of 67 participants were randomized. Follow-up mail assessments were completed by 53 participants. Of 224 potential intervention calls, 194 were completed (87%). Psychosocial measures significantly improved in four of the five factors for physical activity motivation relative to participants in the usual care arm. The more internally focused factors for exercise self-regulation and outcome expectancies scores were significantly greater for participants in intervention compared with usual care. Moderate to vigorous physical activity improved in intervention participants relative to usual care, but the difference was not statistically significant. No adverse events were noted. CONCLUSIONS: The objectives of this pilot study were met. If a fully powered trial is successful, primary care settings with "behind-the-scenes" information technology support may be appropriate to increase physical activity among patients with prediabetes and diabetes.

RESUMO

Since 1990, a wide range of palliative care services has been implemented throughout the Catalan Health Care System. In 2005, 21,400 patients received palliative care; 59% had cancer (79.4% of all cancer patients) and 41% had other noncancer diagnoses (25.0%-56.5% of all noncancer patients). Today, more than 95% of Catalonia is covered by palliative care services. Fourteen districts have comprehensive palliative care networks. A total of 140 full-time physicians work in 183 specialty programs, including 63 palliative care units (with a total of 552 beds), 34 hospital consult teams, 70 home care teams, 16 outpatient clinics, and specialized pediatric and HIV/AIDS consult teams. Opioid consumption increased from 3.5mg per capita in 1989 to 21 mg per capita population in 2004. The cost of the specialist palliative care network is more than 40 million Euros annually. However, the cost efficiency is striking. Due to the radical change in the use of acute and emergency beds, the project saves the Catalan Health Care System an estimated 48 million Euros annually, a net savings of 8 million Euros annually. Additional preliminary data suggest that symptom control and patient/family satisfaction are both improved by these services.
