A Phase 3 Trial of Seladelpar in Primary Biliary Cholangitis.

BACKGROUND: Effective treatments for patients with primary biliary cholangitis are limited. Seladelpar, a peroxisome proliferator-activated receptor delta agonist, has potential benefits. METHODS: In this phase 3, 12-month, double-blind, placebo-controlled trial, we randomly assigned (in a 2:1 ratio) patients who had had an inadequate response to or who had a history of unacceptable side effects with ursodeoxycholic acid to receive oral seladelpar at a dose of 10 mg daily or placebo. The primary end point was a biochemical response, which was defined as an alkaline phosphatase level less than 1.67 times the upper limit of the normal range, with a decrease of 15% or more from baseline, and a normal total bilirubin level at month 12. Key secondary end points were normalization of the alkaline phosphatase level at month 12 and a change in the score on the pruritus numerical rating scale (range, 0 [no itch] to 10 [worst itch imaginable]) from baseline to month 6 among patients with a baseline score of at least 4 (indicating moderate-to-severe pruritus). RESULTS: Of the 193 patients who underwent randomization and treatment, 93.8% received ursodeoxycholic acid as standard-of-care background therapy. A greater percentage of the patients in the seladelpar group than in the placebo group had a biochemical response (61.7% vs. 20.0%; difference, 41.7 percentage points; 95% confidence interval [CI], 27.7 to 53.4, P<0.001). Normalization of the alkaline phosphatase level also occurred in a greater percentage of patients who received seladelpar than of those who received placebo (25.0% vs. 0%; difference, 25.0 percentage points; 95% CI, 18.3 to 33.2, P<0.001). Seladelpar resulted in a greater reduction in the score on the pruritus numerical rating scale than placebo (least-squares mean change from baseline, -3.2 vs. -1.7; least-squares mean difference, -1.5; 95% CI, -2.5 to -0.5, P = 0.005). Adverse events were reported in 86.7% of the patients in the seladelpar group and in 84.6% in the placebo group, and serious adverse events in 7.0% and 6.2%, respectively. CONCLUSIONS: In this trial involving patients with primary biliary cholangitis, the percentage of patients who had a biochemical response and alkaline phosphatase normalization was significantly greater with seladelpar than with placebo. Seladelpar also significantly reduced pruritus among patients who had moderate-to-severe pruritus at baseline. The incidence and severity of adverse events were similar in the two groups.

Weight loss and cardiovascular disease risk outcomes of semaglutide: a one-year multicentered study.

BACKGROUND/OBJECTIVE: There are limited real-world studies assessing semaglutide weight loss and associated comorbidity and metabolic outcomes over periods ≥ 6 months. We aim to assess weight loss, metabolic, and cardiovascular outcomes of 12 months of semaglutide. SUBJECT/METHODS: We conducted a multicentered retrospective cohort study on semaglutide use. We included patients with a body-mass index (BMI) ≥ 27 kg/m2 who were prescribed weekly semaglutide subcutaneous injections. We excluded patients with bariatric surgeries, taking other anti-obesity medications, and with active malignancy or pregnancy. A total of 1023 patients had semaglutide prescription for obesity. INTERVENTION/METHODS: We assessed weight loss outcomes of subcutaneous semaglutide for 12 months. The primary endpoint was total body weight loss percentage (TBWL%) at 12 months. Secondary endpoints included proportion of patients achieving ≥5%, ≥10%, ≥15%, and ≥20% weight loss, and improvements in metabolic, cardiovascular, and comorbidities after 12 months of follow-up. RESULTS: We included 304 patients (73% female, 93% White, mean age 48.8 [12.4] years, BMI 40.9 [9.6] kg/m2) in the analysis. Patients achieved a TBWL of 13.4 (8.0)% at 12 months (p < 0.001 from baseline). Patients without T2DM achieved a TBWL of 16.9 (6.9)% compared to 9.9 (8.4)% in patients without T2DM at 12 months on the higher doses of semaglutide (p < 0.001 from baseline). In this cohort, 81% achieved ≥5%, 64% achieved ≥10%, 41% achieved ≥15%, and 22% achieved ≥20% TBWL at 12 months. Patients with overweight or obesity experienced significant improvements in metabolic, lipid profile, blood pressure, liver function tests, and cardiovascular disease risk outcomes. CONCLUSIONS: Semaglutide demonstrated notable improvement in obesity, metabolic, and cardiovascular disease risk outcomes in a clinical setting.

The Efficacy of the SinHumo App Combined With a Psychological Treatment to Quit Smoking: A Randomized Clinical Trial.

INTRODUCTION: This study assessed the efficacy of the SinHumo App combined with a cognitive-behavioral smoking cessation treatment on 12-month follow-up abstinence, compared with the same smoking cessation treatment and a control App. AIMS AND METHODS: A sample of 288 treatment-seeking people who smoke were randomized: SinHumo App plus smoking cessation treatment (n = 140) and control App plus smoking cessation treatment (n = 148). The primary outcome was 7-day point prevalence abstinence (PPA) at the 12-month follow-up. Secondary outcomes were abstinence rates at the end of the intervention and 3- and 6-month follow-ups, cigarette per day (CPD) reduction over the 12-month follow-up, intervention engagement, and satisfaction. RESULTS: Intention-to-treat analyses showed nonsignificant differences in self-reported 7-day PPA at the 12-month follow-up (37.1 and 42.6%, respectively; OR = 0.80). No significant differences were found in abstinence at the end of the treatment (68.6 vs. 62.8%) nor on 7-day PPA at 3- (35.7 vs. 45.9%) and 6-month (35.0 vs. 41.2%) follow-up. Complete case and multiple imputation analyses yielded similar results for abstinence outcomes. A significant reduction in CPD across the 12-month follow-up in the subsample of participants who smoked was observed, but nonsignificant differences between conditions were found. Higher engagement with the SinHumo App was a significant predictor of 12-month abstinence. Satisfaction with the intervention was high and similar in both groups. CONCLUSIONS: High abstinence rates over the 12-month follow-up and satisfaction were found in both conditions. The inclusion of the SinHumo App did not improve abstinence rates in the intervention. IMPLICATIONS: Scarce research has examined the long-term efficacy of smoking cessation treatments, including Apps, to support the quitting process. The present randomized controlled trial contributes to the existing literature about including information and communication technologies in behavior change interventions. The development of effective smoking cessation apps and information and communication technologies-based interventions is crucial for reducing the prevalence of smoking, as these interventions have the potential to reach a large number of people who smoke and reduce access-related barriers to treatment.

Measurement properties of the Foot Function Index (FFI) questionnaire: A systematic review.

OBJECTIVE: Large numbers of people are subject to alterations and pathologies in the foot. To quantify how these problems of foot function affect the quality of life, clinicians and researchers have developed measures such as the Foot Function Index (FFI). Our aim is to determine the methodological quality of the FFI including adaptations to other languages. DATA SOURCES: The studies considered in this review were extracted from the PubMed, Embase and CINAHL databases. The inclusion criteria were followed: (1) studies of patients with no previous foot or ankle pathology and aged over 18 years; (2) based on English-language patient-reported outcome measures that assess foot function; (3) the patient-reported outcome measures should present measurement properties based on COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria. REVIEW METHODS: The systematic review was conducted following the COSMIN criteria to establish the methodological quality of the original FFI, together with its variants and adaptations. The last search was carried out in May 2024. RESULTS: Of the 1994 studies obtained in the preliminary search, 20 were eligible for inclusion in the final analysis. These results are the validations and cross-cultural adaptations to the following languages: the original FFI has cross-cultural adaptation in 13 languages and the FFI-Revised Short Form has been adapted and validated for use in 2 languages. CONCLUSION: In terms of methodological quality, the FFI-Revised Short Form questionnaire is a valuable instrument for evaluating ankle and foot function and could usefully be expanded to be available in more languages.

"Sustaining the burden". A qualitative study on the emotional impact and social functioning of family caregivers of patients with psychosis.

Evidence shows that caring for a family member with a psychotic disorder generates a significant emotional impact and repercussions on social functioning. However, this caregiving experience can be influenced by cultural factors. The aim of this study is to explore the experience and perception of a group of family caregivers of patients with psychotic disorders of different durations regarding the emotional and social functioning repercussions of caregiving on them in Andalusia. Three focus groups (28 participants) were conducted. Data were subject to a thematic analysis. Three themes emerged from the data: 1) Emotional invasion; 2) Disruption in the caregiver's life project; and 3) Changes in the family system. Participants reported experiencing sadness, fear, overwhelm, hopelessness, and uncertainty. Caregivers' accounts reflected an interruption of their daily tasks, as well as the need to reformulate plans or goals outside the family life that require long-term commitment, such as professional development or even their residence. The narratives indicated an impact on all roles within the family system, particularly for the mother. The results are consistent with existing research. Healthcare professionals and programs should take into account the costs associated with caregiving in order to minimize them, given the impact it has on both the patient's and the caregivers' health.

Personal relationships during and after an initial psychotic episode. First-person experiences.

BACKGROUND: Psychosis is often associated with loneliness, the absence of a confidant and a perceived lack of social support. In addition, the social isolation and solitude experienced can aggravate internalised stigma, depressive symptoms and/or suicidal tendencies, and worsen the course of the disorder. AIM: This study explores the experiences and perceptions of persons with psychosis concerning how their interpersonal relationships have evolved from the earliest symptoms of the disorder to its subsequent clinical stabilisation. METHOD: A qualitative content analysis was performed of the findings from five focus groups and six in-depth interviews (36 participants). RESULTS: In the prodrome and initial symptoms stage, five themes were coded: social withdrawal, loss of friends, loss of personal skills, communication difficulties and breakdown of life project. During the recovery phase, four themes were coded: family support, partner support, loneliness and the desire for more close relationships. Finally, during the clinical stabilisation phase, three themes were coded: the recovery of interpersonal relationships, including with peers; reconstruction of the life project and increased interpersonal sensitivity. CONCLUSIONS: These findings highlight the impact that psychosis can have on social life and show that recovery is also related to the development of maeningful interpersonal relationships.

Non-random interactions within and across guilds shape the potential to coexist in multi-trophic ecological communities.

Theory posits that the persistence of species in ecological communities is shaped by their interactions within and across trophic guilds. However, we lack empirical evaluations of how the structure, strength and sign of biotic interactions drive the potential to coexist in diverse multi-trophic communities. Here, we model community feasibility domains, a theoretically informed measure of multi-species coexistence probability, from grassland communities comprising more than 45 species on average from three trophic guilds (plants, pollinators and herbivores). Contrary to our hypothesis, increasing community complexity, measured either as the number of guilds or community richness, did not decrease community feasibility. Rather, we observed that high degrees of species self-regulation and niche partitioning allow for maintaining larger levels of community feasibility and higher species persistence in more diverse communities. Our results show that biotic interactions within and across guilds are not random in nature and both structures significantly contribute to maintaining multi-trophic diversity.

Low Incidence of Pulmonary Aspiration During Upper Endoscopy in Patients Prescribed a Glucagon-Like Peptide 1 Receptor Agonist.

Glucagon-like peptide 1 (GLP-1) receptor agonists have transformed the treatment of type 2 diabetes and obesity. These agents have been associated with varying degrees of delay in gastric emptying, and a significant proportion of patients experience digestive side effects.1 There have been previous case reports of gastric retention of food and pulmonary aspiration during upper gastrointestinal (GI) endoscopy in the setting of GLP-1 receptor agonist use2; however, the cumulative incidence has not been previously explored.

Efficacy of Antiobesity Medications in Patients With Celiac Disease on a Gluten-free Diet: A Retrospective Matched Cohort Study.

GOALS: We aim to describe the weight loss outcomes of patients with celiac disease (CeD) taking antiobesity medications (AOMs) and compare it with the weight loss outcomes of patients without CeD taking AOMs. BACKGROUND: Increasing rates of obesity and obesity-associated comorbidities have been previously reported in patients with CeD on a gluten-free diet. The effectiveness of AOMs in this population has not been previously described. METHODS: In our retrospective cohort study, we matched 39 patients with treated CeD to 78 patients without CeD based on sex and AOM. We assessed the weight loss outcomes at 3, 6, and 12 months after starting the AOM in both cohorts and analyzed if there was a differential response when comparing by type of AOM [injectable glucagon-like peptide 1 (GLP-1) receptor agonists vs. oral non-GLP-1 AOMs]. RESULTS: Both cohorts had similar baseline demographic and anthropometric characteristics. At 12 months, the CeD cohort had a nonsignificantly inferior total body weight loss percentage compared with the cohort without CeD (6.5% vs. 9.5%, P=0.13). The CeD cohort had a similar proportion of patients achieving a total body weight loss percentage of ≥5% than the cohort without CeD (72.7% vs. 72.1%, P=1.00). No significant difference was observed when comparing the weight loss outcomes of injectables (GLP-1 receptor agonists) to oral AOMs. The proportion of patients reporting side effects was similar for both groups, regardless of the type of AOM. CONCLUSION: Patients with CeD taking AOMs had similar weight loss outcomes to patients without CeD. Hence, AOMs can be a safe and effective therapy for weight management in patients with CeD.

Effect of caloric intake and macronutrient composition on intestinal cholesterol absorption and bile acids in patients with obesity.

Obesity is associated with alterations in cholesterol and bile acid (BA) metabolism. However, the interaction among dietary intake, cholesterol absorption, and BA metabolism in patients with obesity remains unclear. We conducted a 4-wk nutritional intervention nonrandomized clinical trial with three different sequential diets for a week in the following order: regular diet (RD); high calorie, high-fat diet (HCHF), washout period on RD; and low-calorie, low-fat diet (LCLF). We provided participants with meal replacements during HCHF and LCLF diets. A total of 16 participants completed the study [n = 8 normal weight (NW); n = 8 with obesity (OB)]. Overall, there was a significant increase in intestinal cholesterol uptake when changing from RD to HCHF and a reduction in intestinal cholesterol uptake from HCHF to LCLF. When analyzing by BMI groups, these findings were similar in patients with NW (RD to HCHF: P < 0.007; HCHF to LCLF: P = 0.02); however, in patients with obesity, the change in intestinal cholesterol uptake was only observed when changing from RD to HCHF (P = 0.006). There was no correlation between cholesterol absorption and fecal bile acids or other markers of BA metabolism in all patients or the subgroups. Dietary caloric content had a significant effect on cholesterol absorption, however, this effect is blunted in patients with obesity. These data are consistent with the impaired effect of a low-fat diet on cholesterol absorption in obesity.NEW & NOTEWORTHY We show how switching from a regular diet to an HCHF increases cholesterol absorption in patients with normal weight and obesity. The decrease in cholesterol absorption from an HCHF to an LCLF, on the other hand, was only seen in normal-weight controls, underlining the importance of body weight in this regulation. In addition, changes in caloric and fat content had an immediate and direct effect on hepatic bile acid production.

Association between CYP metabolizer phenotypes and selective serotonin reuptake inhibitors induced weight gain: a retrospective cohort study.

BACKGROUND: Prescription medications such as selective serotonin reuptake inhibitors (SSRIs), commonly used to treat depression, are associated with weight gain. The role of pharmacogenomics in predicting SSRI-induced weight gain is unclear. METHODS: In this retrospective cohort study from participants in the Mayo Clinic RIGHT study who were prescribed citalopram, paroxetine, sertraline, or fluoxetine, our aim was to evaluate the association of metabolizer phenotype and total body weight after 6 months of SSRIs initiation. We evaluated the metabolizer phenotypes (poor/intermediate, normal, and rapid/ultra-rapid) of the cytochromes P450 enzymes genes: CYP2C9, CYP2C19, and CYP2D6 known to influence the metabolism of SSRI medications: CYP2C19 for citalopram, CYP2D6 for paroxetine, CYP2D6 and CYP2C19 for sertraline, and CYP2D6 and CYP2C9 fluoxetine. In addition, we assessed the association of metabolizer phenotype and total body weight change at six months following SSRI prescription using parametric analysis of covariance adjusted for baseline body weight and multivariate regression models. RESULTS: CYP2C19 poor/intermediate metabolizers prescribed citalopram gained significantly more weight than normal or rapid/ultra-rapid metabolizers at 6 months (TBWG %: 2.6 [95% CI 1.3-4.1] vs. 0.4 [95% CI -0.5 - 1.3] vs. -0.1 [-95% CI -1.5-1.1]; p = 0.001). No significant differences in weight outcomes at six months of treatment with paroxetine, sertraline, or fluoxetine were observed by metabolizer status. CONCLUSIONS: Weight gain observed with citalopram may be mediated by CYP2C19 metabolizer status.

Sex as an independent variable in the measurement of satiation: a retrospective cohort study.

BACKGROUND: Satiation is a key component of food intake regulation as it brings an eating episode to an end. The effect of sex on satiation measurement has not been characterized. OBJECTIVE: To assess the effects of biological variables on satiation. DESIGN: Retrospective cohort study. We included 959 participants (mean age 39 [SD 12] years; 70.7% female, and BMI 33 kg/m2 [8]) who had measurements of satiation with a nutrient-drink test to assess volume to fullness (VTF) and maximum tolerated volume (MTV), and/or an ad libitum meal test to assess calories consumed to fullness (CTF). We performed univariate and multiple regression analyses to estimate the contribution of sex to VTF, MTV, and CTF, compared to other biological variables, such as age, weight, height, BMI, waist-to-hip circumference (W/H), and lean mass percentage (LM%), that are known to affect these parameters. RESULTS: Females had higher BMI, W/H, and LM%. VTF, MTV, and CTF were lower in females: 704 [323] vs. 783 [328] mL, p = 0.001; 1226 [384] vs. 1419 [410] mL, p < 0.001; and 871 [291] vs. 1086 [326] kcal, p < 0.001; respectively. Sex was a strong and independent predictor of VTF, MTF and CTF: parameter estimate [PE] = -80.8, p = 0.006; PE = -124.2, p = 0.0007; and PE = -110, p = 0.001; respectively. CONCLUSIONS: Sex has a strong effect on satiation measured by VTF, MTV, and CTF, even after adjusting for other biological factors known to affect these parameters. Females seem to integrate intra-meal inhibition signals to consume fewer calories unrelated to body size or composition. CLINICAL TRIAL REGISTRATION: None.

Precision Medicine and Obesity.

Obesity is a chronic, relapsing, and multifactorial disease, with a rising prevalence and an associated high economic burden. Achieving successful and sustained weight loss outcomes with current interventions is challenging. This is due, at least in part, to the disease's heterogenous pathophysiology that is yet to be completely understood. Technological advances and greater capabilities for the extraction and storage of information have facilitated the application of precision medicine. Several precision medicine initiatives have been proposed to improve obesity outcomes. Most of these initiatives are based on -omics technologies. Although the data generated from these technologies have led to developing hypotheses that may explain the underpinnings of obesity, their applicability to the clinical practice is yet to be determined. There are other initiatives that have identified quantitative or qualitative physiologic traits that can be targeted and that could have a more immediate clinical impact. This review aims to provide a perspective of current initiatives for precision medicine for obesity.

Study protocol: a randomised, controlled trial of a nurse navigator program for the management of hepatitis C virus in patients with severe mental disorder.

BACKGROUND: To evaluate the impact of a nurse navigation program on treatment adherence and resolution of hepatitis C infection in patients with severe mental disorder. METHODS: An open, randomized, controlled trial with blinded outcome assessment. The intervention group will engage in a nurse navigation program designed by mental health nurses. The program involves active screening for patients with severe mental disorder. The patients and caregivers included in the program will receive information, training, support and guidance throughout the treatment and recovery process, which involves different healthcare professionals and units. The control group will receive the standard of care, which includes follow-up by a family physician, referral to the hepatologist, serological testing, new referral to the hepatologist, onset of treatment, and follow-up. Multidisciplinary care will be provided along a coordinated and seamless clinical pathway led by a nurse navigator. The primary endpoints are total recovery (hepatitis C cure) and treatment adherence. Occurrence of symptoms of schizophrenia and health-related quality of life will be also recorded. Follow-up of patients will be performed three and six months after the administration of antiviral treatment. The study was authorised by the Ethics Committee of Malaga in December 2021. Funding was approved in March 2021. DISCUSSION: If this intervention is proven to be effective in improving treatment access and adherence, it will represent a step forward in addressing a chronic health issue that is 16 times more prevalent in the population with severe mental disease. Finally, this intervention may lead to the detection of undertreated HCV infection in this population of patients. TRIAL REGISTRATION: This protocol has been registered in ClinicalTrials.gov with identifier code NCT04891445 on May 18, 2021.

Use of the ADAPTE method to develop a clinical guideline for the improvement of psychoses and schizophrenia care: Example of involvement and participation of patients and family caregivers.

INTRODUCTION: The aim of this study is to analyse different ways of participation during the development of a clinical guideline to improve the early detection of psychosis and to deploy a comprehensive treatment plan to improve prognosis and social integration. MATERIALS AND METHOD: The clinical guideline was developed using the ADAPTE method with the participation of 40 authors and 80 external reviewers. The process was divided into three major phases: set up, adaptation and finalization. During adaptation and completion, a total of 44 patients and 18 family caregivers were involved. RESULTS AND CONCLUSIONS: The different roles assumed by the patients and their family caregivers were described, depending on the panel in which they participated, with diverse grades of complexity: a user as author, integration of the results of qualitative research with the participation of local users and family caregivers, 13 users as individual external reviewers and the participation of users and caregiver organizations in the external review. In the guideline, contributions from patients during the qualitative research were included in an innovative way, placing them just behind the recommendations. On the other hand, the results of the family caregivers' study were included in a specific area of uncertainty. Further, the expressed point of view was considered as the collective demands of users and family caregivers' organizations in the cost-benefit analysis made by the organizing committee. There were diverse ways to conduct direct patient participation during the guideline development, ensuring that their individual experiences contributed significantly to the final version.

Should cyclosporine be useful in renal transplant recipients affected by SARS-CoV-2?

Minimization of immunosuppression and administration of antiretrovirals have been recommended for kidney transplant recipients (KTRs) with coronavirus disease 2019 (COVID-19). However, outcomes remain poor. Given the likely benefit of cyclosporine because of its antiviral and immunomodulatory effect, we have been using it as a strategy in KTRs diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We studied 29 kidney transplant recipients (KTRs) who were admitted to our institution with COVID-19 between March 15and April, 24, 2020. Mycophenolate and/or mammalian target of rapamycin inhibitors (mTORi) were discontinued in all patients. Two therapeutic strategies were compared: Group 1, minimization of calcineurin inhibitors (N = 6); and Group 2, cyclosporine-based therapy (N = 23), with 15 patients switched from tacrolimus. Hydroxychloroquine was considered in both strategies but antivirals in none. Six patients died after respiratory distress (20.6%). Five required mechanical ventilation (17.2%), and 3 could be weaned. Nineteen patients had an uneventful recovery (65.5%). In group 1, 3 of 6 patients died (50%) and 1 of 6 required invasive mechanical ventilation (16.7%). In group 2, 3 of 23 patients died (12.5%). Renal function did not deteriorate and signs of rejection were not observed in any patient on the second treatment regime. In conclusion, immunosuppressant treatment based on cyclosporine could be safe and effective for KTRs diagnosed with COVID-19.

Sensor-based systems for early detection of dementia (SENDA): a study protocol for a prospective cohort sequential study.

BACKGROUND: Dementia and cognitive decline are serious social and economic burdens. An increase in the population of older people, as well as longer lifespans mean that numbers of dementia cases are exponentially rising. Neuropathological changes associated with dementia are thought to appear before the clinical manifestation of cognitive symptoms, i.e., memory impairments. Further, some older adults (OA) experience cognitive decline before it can be objectively diagnosed. For optimal care of these patients, it is necessary to detect cognitive decline and dementia at an early stage. In this vein, motor, sensory, and neurophysiological declines could be promising factors if found to be present before the onset of cognitive impairment. Hence, the objective of the SENDA study is to develop a multi-dimensional sensor-based instrument that allows early detection of cognitive decline or dementia in OA with the help of cognitive, sensory, motor, and neurophysiological parameters before its clinical manifestation. METHODS/DESIGN: In the cohort sequential study, participants are assigned to one of three study groups depending on their cognitive status: 1. cognitively healthy individuals (CHI), 2. subjectively cognitively impaired persons (SCI), or 3. (possible) mildly cognitively impaired persons (pMCI, MCI). All groups take part in the same cognitive (e.g., executive function tests), motor (e.g., gait analyses, balance tests), sensory (e.g., vibration perception threshold test, proprioception tests), and neurophysiological (e.g., electroencephalograms) measurements. Depending on the time at which participants are included into the study, all measurements are repeated up to four times in intervals of 8 months within 3 years to identify associations with cognitive changes over time. DISCUSSION: This study aims to detect possible motor, sensory, neurophysiological, and cognitive predictors to develop an early screening tool for dementia and its pre-stages in OA. Thus, affected persons could receive optimal health care at an earlier time point to maintain their health resources. TRIAL STATUS: The study is ongoing. The recruitment of participants will be continued until May 2020.

Drivers of the Decision to Biopsy and Follow-Up of Small Suspicious Thyroid Nodules.

OBJECTIVE: In 2015, the updated American Thyroid Association (ATA) guidelines recommended observation for suspicious subcentimeter thyroid nodules, based on their indolent course. We aimed to evaluate the frequency of biopsy in suspicious thyroid nodules since the introduction of these guidelines, including factors contributing to clinical decision-making in a tertiary care center. METHODS: We conducted a retrospective study of patients in the Mayo Clinic, Rochester, Minnesota, with new, subcentimeter suspicious thyroid nodules (by report or by sonographic features) between March, 2015, and November, 2017, not previously biopsied. RESULTS: We identified 141 nodules in 129 patients: mean age 58.1±14.1 years, 74% female, 87% Caucasian. The frequency of biopsy in suspicious thyroid nodules was 39%. Ultrasound features that were the strongest predictors for biopsy on multivariate analysis included: nodule volume (odds ratio [OR] 37.3 [7.5-188.7]), radiology recommendation for biopsy (OR 2.6 [1.8-3.9]) and radiology report of the nodule as "suspicious" (OR 2.1 [1.4-3.2]). Patient's age and degree of comorbidities did not change the likelihood for biopsy, nor did it vary by clinician type or how the nodule was initially found (incidentally or not incidentally). Among 86 nodules that were not biopsied, 41% had no specific follow-up recommendations. CONCLUSION: One third of suspicious thyroid nodules underwent biopsy since the release of updated ATA guidelines. Factors driving thyroid biopsy seem to be associated with nodule characteristics but not with patient factors including age and comorbidities. Further studies and development of decision aides may be helpful in providing individualized approaches for suspicious thyroid nodules. ABBREVIATIONS: ATA = American Thyroid Association; OR = odds ratio.

Development of a guideline for the treatment of generalized anxiety disorder with the ADAPTE method.

OBJECTIVE: The aim was to develop a clinical guideline for managing generalised anxiety disorder in Primary Health Care and Mental Health, using guideline adaptation methods. DESIGN: A clinical guideline was developed, following the methods of the ADAPTE group, and implemented in a Primary Health Care District and in Mental Health Services in Spain. SETTING: Regional University Hospital of Málaga and District of Primary Health Care Málaga-Guadalhorce (Spain). PARTICIPANTS: The participants were family physicians, psychiatrists and clinical psychologists. The phases of the process included definition of clinical scenarios, literature search and guidelines appraisal, elaboration of recommendations, conducting focus groups with users diagnosed with generalised anxiety disorder, linking the testimonials of users with recommendations, external review and implementation by multifaceted interventions. RESULTS: The final release included 49 Recommendations, of which 47 are from the 2011 NICE guidance for GAD and 2 of the 2011 NICE guideline for common mental disorder. Finally, seven recommendations needed to be adapted to the Spanish health care context, and three recommendations were excluded. CONCLUSIONS: A guideline aimed to improve the quality and effectiveness of the care provided to people with generalised anxiety disorder has been released. The use of adaptation methods has simplified the use of resources and time. This guideline and the process designed for its implementation constitute a suitable collection of resources for the improvement on detection and treatment of GAD in primary health care. Adaptation methods play a key role in the knowledge translation continuum.
