RESUMEN

BACKGROUND: To implement a goal-directed fluid therapy (GDFT) protocol using crystalloids in hip revision arthroplasty surgery within a quality management project at a tertiary hospital using a monocentric, prospective observational study. METHODS: Adult patients scheduled for elective hip revision arthroplasty surgery were screened for inclusion in this prospective study. Intraoperatively stroke volume (SV) was optimized within a previously published protocol using uncalibrated pulse contour analysis and balanced crystalloids. Quality of perioperative GDFT was assessed by protocol adherence, SV increase as well as the rate of perioperative complications. Findings were then compared to two different historical groups of a former trial: one receiving GDFT with colloids (prospective colloid group) and one standard fluid therapy (retrospective control group) throughout surgery. Statistical analysis constitutes exploratory data analyses and results are expressed as median with 25th and 75th percentiles, absolute and relative frequencies, and complication rates are further given with 95% confidence intervals for proportions using the normal approximation without continuity correction. RESULTS: Sixty-six patients underwent GDFT using balanced crystalloids and were compared to 130 patients with GDFT using balanced colloids and 130 controls without GDFT fluid resuscitation. There was a comparable increase in SV (crystalloids: 65 (54-74 ml; colloids: 67.5 (60-75.25 ml) and total volume infused (crystalloids: 2575 (2000-4210) ml; colloids: 2435 (1760-3480) ml; and controls: 2210 (1658-3000) ml). Overall perioperative complications rates were similar (42.4% (95%CI 30.3-55.2%) for crystalloids and 49.2% (95%CI 40.4-58.1%) for colloids and lower compared to controls: 66.9% (95%CI 58.1-74.9)). Interestingly, a reduced number of hemorrhagic complications was observed within crystalloids: 30% (95%CI 19.6-42.9); colloids: 43% (95%CI 34.4-52.0); and controls: 62% (95%CI 52.6-69.9). There were no differences in the rate of admission to the post-anesthesia care unit or intensive care unit as well as the length of stay. CONCLUSIONS: Perioperative fluid management using a GDFT protocol with crystalloids in hip revision arthroplasty surgery was successfully implemented in daily clinical routine. Perioperative complications rates were reduced compared to a previous management without GDFT and comparable when using colloids. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01753050.

RESUMEN

To examine long-term effects of early intervention services (EIS) for first-episode psychosis, we compared Heinrichs-Carpenter Quality of Life (QLS) and Positive and Negative Syndrome Scale (PANSS) scores and inpatient hospitalization days over 5 years with data from the site-randomized RAISE-ETP trial that compared the EIS NAVIGATE (17 sites; 223 participants) and community care (CC) (17 sites; 181 participants). Inclusion criteria were: age 15-40 years; DSM-IV diagnoses of schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, or psychotic disorder not otherwise specified; first psychotic episode; antipsychotic medication taken for ≤6 months. NAVIGATE-randomized participants could receive NAVIGATE from their study entry date until NAVIGATE ended when the last-enrolled NAVIGATE participant completed 2 years of treatment. Assessments occurred every 6 months. 61% of participants had assessments conducted ≥2 years; 31% at 5 years. Median follow-up length was CC 30 months and NAVIGATE 38 months. Primary analyses assumed data were not-missing-at-random (NMAR); sensitivity analyses assumed data were missing-at-random (MAR). MAR analyses found no significant treatment-by-time interactions for QLS or PANSS. NMAR analyses revealed that NAVIGATE was associated with a 13.14 (95%CI:6.92,19.37) unit QLS and 7.73 (95%CI:2.98,12.47) unit PANSS better improvement and 2.53 (95%CI:0.59,4.47) fewer inpatient days than CC (all comparisons significant). QLS and PANSS effect sizes were 0.856 and 0.70. NAVIGATE opportunity length (mean 33.8 (SD = 5.1) months) was not associated (P = .72) with QLS outcome; duration of untreated psychosis did not moderate (P = .32) differential QLS outcome. While conclusions are limited by the low rate of five-year follow-up, the data support long-term benefit of NAVIGATE compared to community care.

RESUMEN

Integrated Coping Awareness Therapy (I-CAT) is an intervention that targets stress reactivity in first-episode psychosis (FEP). This study extends prior outcome research on I-CAT by examining predictors of online daily diary completion among 38 young adults with FEP and treatment group differences in diary ratings. We found no significant predictors of daily diary completion rate and no effect of treatment condition on diary ratings. These results are consistent with Halverson et al. (2021) and suggest that diaries are a valuable method of data collection in FEP.

RESUMEN

Individuals with schizophrenia spectrum disorders (SSD) are at heightened risk for exposure to stressful life events which can lead to increased sensitivity to stress and a dysregulated stress response, which are in turn associated with poor long-term functioning. Stress reactivity is thus a promising treatment target in the early stages of SSD. Integrated-Coping Awareness Therapy (I-CAT) is a manualized intervention integrating mindfulness and positive psychology to target a dysregulated stress response in SSD. The current study is a preliminary randomized-controlled trial (RCT) comparing I-CAT (n = 18) with treatment as usual (TAU; n = 18) in individuals in the early stages of SSD. I-CAT was hypothesized to be more effective than TAU on primary outcomes: increasing positive emotions, decreasing negative emotions, reducing stress, and improving functioning and quality of life; and secondary outcomes: reducing symptoms, increasing mindfulness, and improving overall well-being. Excellent therapy attendance rates, low study attrition, and positive participant feedback demonstrated that I-CAT was a feasible and well-tolerated psychosocial intervention. Results suggest I-CAT led to greater reduction in symptoms (i.e., overall, negative, and disorganized symptoms), increased observational mindfulness, increased endorsement of a sense of purpose in life, and preservation of work abilities and school social functioning compared with TAU. Future work should replicate and extend these findings in a larger-scale RCT.

RESUMEN

INTRODUCTION: Diminished motivation (e.g., low drive, curiosity, and engagement in activities) is associated with robust impairment in psychosocial functioning in schizophrenia, yet even the most effective evidence-based interventions rarely effect meaningful change in motivation. Individual Resiliency Training (IRT) is a psychosocial treatment for individuals following a first episode of psychosis, supporting motivation through recovery goal setting and pursuit. The extent to which such an approach might improve motivation over time is unknown. METHOD: We tested the impact of exposure to IRT modules focused on goal setting and attainment on motivation and functional outcomes among participants in the Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP). In the sample of 404 individuals with a first episode of psychosis receiving treatment across 34 community sites, we ran mixed-effect models with group (exposed to four or more goal-focused IRT sessions vs. Community Care (CC)), time (baseline, six- and 12-month follow-up), and the group-by-time interaction as predictors of motivation, role and social functioning. We also ran these analyses with those exposed to three or fewer goal-focused IRT sessions compared to CC. RESULTS: Controlling for gender, ethnicity, baseline cognition, and total number of outpatient mental health visits, exposure to four or more goal-focused IRT sessions was associated with greater improvements in motivation and role functioning compared to CC; effects were not observed for social functioning. Participants receiving three or fewer goal-focused IRT sessions did not differ from those in CC in these outcomes. Further, sensitivity analysis showed that general exposure to IRT was not associated with differential outcomes. CONCLUSIONS: Findings suggest that sufficient focus on recovery goal setting and support in psychosocial intervention for first-episode psychosis may have specific impact on motivation.

RESUMEN

Background: Acute secondary peritonitis is afflicted with a high morbidity and mortality. Intensive care therapy, antibiotics and surgical procedures are mandatory. Continuous negative pressure therapy (cNPT) seems to be beneficial but it is unclear which patients will benefit most from this procedures.Methods: We performed a prospective observational trial including all patients that needed to undergo an exploratory laparotomy for the suspicion of acute secondary peritonitis and were treated with cNPT in one year.Results: Thirty nine patients fitted the criteria. Median hospitalization length was 40 days. The vacuum therapy treatment was applied for a median of 4 days. The subgroup analysis between patients, who received the cNPT-dressing for one time (Group A) and patients, in whom the cNPT was continued after first relaparotomy (Group B) showed no differences concerning patients' characteristics. The Mannheimer Peritonitis Index (MPI) during the first operation was significantly correlated with the number of dressing changes (Spearman's rho 0.518, p = .002).Conclusions: Fast acting in acute secondary peritonitis for elimination of the source, abdominal lavage, derivation of the exsudat and interdisciplinary treatment is the treatment of choice. The MPI could be beneficial for the decision process of using cNPT.

RESUMEN

BACKGROUND: Almost 40% of stroke patients have a poor outcome at 3 months after the index event. Predictors for stroke outcome in the early acute phase may help to tailor stroke treatment. Infection and inflammation are considered to influence stroke outcome. METHODS: In a prospective multicenter study in Germany and Spain, including 486 patients with acute ischemic stroke, we used multivariable regression analysis to investigate the association of poor outcome with monocytic HLA-DR (mHLA-DR) expression, interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor alpha (TNF-alpha) and lipopolysaccharide-binding protein (LBP) as markers for immunodepression, inflammation and infection. Outcome was assessed at 3 months after stroke via a structured telephone interview using the modified Rankin Scale (mRS). Poor outcome was defined as a mRS score of 3 or higher which included death. Furthermore, a time-to-event analysis for death within 3 months was performed. RESULTS: Three-month outcome data was available for 391 patients. Female sex, older age, diabetes mellitus, atrial fibrillation, stroke-associated pneumonia (SAP) and higher National Institute of Health Stroke Scale (NIHSS) score as well as lower mHLA-DR levels, higher IL-6 and LBP-levels at day 1 were associated with poor outcome at 3 months in bivariate analysis. Furthermore, multivariable analysis revealed that lower mHLA-DR expression was associated with poor outcome. Female sex, older age, atrial fibrillation, SAP, higher NIHSS score, lower mHLA-DR expression and higher IL-6 levels were associated with shorter survival time in bivariate analysis. In multivariable analysis, SAP and higher IL-6 levels on day 1 were associated with shorter survival time. CONCLUSIONS: SAP, lower mHLA-DR-expression and higher IL-6 levels on day one are associated with poor outcome and shorter survival time at 3 months after stroke onset.

RESUMEN

The NAVIGATE program was developed for the Recovery After Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study, which compared NAVIGATE to usual Community Care in a cluster randomized design involving 34 sites and 404 patients. This article describes the approach to training and implementing the NAVIGATE program at the 17 sites (including 134 practitioners) randomized to provide it, and to evaluating the fidelity of service delivery to the NAVIGATE model. Fidelity was evaluated to five different components of the program, all of which were standardized in manuals in advance of implementation. The components included four interventions (Individualized Resiliency Training, Family Education Program, Supported Employment and Education, Personalized Medication Management) and the overall organization (staffing and structure) of the NAVIGATE team. Most of the sites demonstrated acceptable or higher levels of fidelity in their implementation of the four interventions and the organization of the program, with all 17 sites demonstrating at least acceptable overall fidelity to the NAVIGATE program. The results indicate that the NAVIGATE program can be implemented with good fidelity to the treatment model in a diverse array of community mental health care settings serving persons with a first episode psychosis.

RESUMEN

INTRODUCTION: Technology-delivered healthcare interventions may enhance dissemination of evidence-based treatments in low-resource areas. These interventions may be accessed 'on-demand,' including after hours. Patients with schizophrenia do engage with technological aids but when/how they would utilize these tools is not known. METHODS: We conducted a large, prospective, ten-site, longitudinal study of four technology-assisted interventions for patients with schizophrenia spectrum disorders within 60 days of psychiatric hospital discharge, a high risk period. One tool employed was a smartphone intervention called 'FOCUS,' which could be used by patients as needed, providing help in five content areas: medications, mood, social, sleep and voices. Each login was date- and time-stamped as occurring during normal clinic hours, or 'off-hours,' and the pattern of use described. RESULTS: 347 of 368 patients utilized FOCUS during the 6-month study. There were a total of 75,447 FOCUS logins; 35,739 (47.4%) were self-initiated and 38,139 (50.6%) were off-hours. 18,450 of the logins during off-hours were self-initiated (24.5%). No differences in average usage per month were found based on race/ethnicity. A subset of 'high utilizers' (n = 152, 43.8%) self-initiated use of all five FOCUS modules both on- and off-hours. They tended to be women, >35 years old, and had a high school diploma or greater. CONCLUSION: Most patients with schizophrenia spectrum disorders recently discharged from the hospital utilized a smartphone intervention targeted to address troublesome residual symptoms. One quarter of the total smartphone utilization was self-initiated off-hours, indicating the potential utility of this tool to extend support for patients during periods of elevated risk.

RESUMEN

BACKGROUND: Evidence-based approaches and early intervention have improved the long-term prognosis of individuals with schizophrenia. However, little is known about the therapeutic processes involved in individual therapy in first-episode psychosis. A comprehensive psychosocial/psychiatric programme for this population, NAVIGATE, includes an individual therapy component, individual resiliency training (IRT). Fidelity of clinicians' adherence to the IRT protocol has been collected to ensure proper implementation of this manual-based intervention. These data can provide insight into the elements of the therapeutic process in this intervention. MATERIALS AND METHODS: To achieve this goal, we first examined the factor structure of the IRT fidelity scale with exploratory factor analysis. Second, we explored the relationships among the IRT fidelity ratings with clinician years of experience and years of education, as well as client's baseline symptom severity and duration of untreated psychosis. RESULTS AND CONCLUSIONS: Results supported a 2-factor structure of the IRT fidelity scale. Correlations between clinician years of education and fidelity ratings were statistically significant.

RESUMEN

This qualitative study assessed the experiences of assertive community treatment (ACT) team members regarding the integration of physical and mental health self-management for persons with serious mental illness. Three focus groups elicited information from participants concerning barriers, strategies, and recommendations. Findings from inductive analyses revealed six overarching themes: (1) collaboration with primary care, (2) improvements in engagement, (3) team-focused roles, (4) education and training, (5) recommendations for system level barriers, and (6) systems collaboration. Participant recommendations suggest that ACT teams are well positioned to integrate mental and physical health treatment, but further research is needed to support integrated care.

RESUMEN

Recovery-oriented practices that promote client-centered care, collaboration, and functional outcome have been recommended to improve treatment engagement, especially for individuals with serious mental illness (SMI). Psychological well-being (PWB) is related to recovery and refers to experiencing purpose and meaning in life through realizing one's potential. The recently completed Recovery After an Initial Schizophrenia Episode Early Treatment Program (RAISE ETP) study sought to improve quality of life, functional outcome, and well-being in individuals with first episode psychosis (FEP). Therefore, the primary aims of the present analysis were: 1) to examine the impact of treatment on PWB and mental health recovery trajectories, 2) to examine the impact of duration of untreated psychosis (DUP) on these outcomes, and 3) to examine the relationships among these outcomes and quality of life. Multilevel modeling was used given the nested data structure. Results revealed that PWB and mental health recovery improved over the course of the 2-year treatment; there were no significant treatment differences. In addition, DUP was associated with the Positive Relationships and Environmental Mastery dimensions of PWB. Finally, PWB, mental health recovery, and quality of life were all significantly correlated at baseline while controlling for depressive symptoms. Overall, the findings indicate that PWB and mental health recovery can improve in FEP, are related to yet distinct from quality of life, and that DUP may play a role in certain facets of these constructs.

RESUMEN

OBJECTIVE: Assertive community treatment (ACT) is one of the few evidence-based practices for adults with severe mental illness. Interest has slowly waned for ACT implementation. Yet ACT remains an appealing services platform to achieve the triple aim of health care reform (improved health outcomes, reduced cost, and improved satisfaction) through integration of primary care and behavioral health services. This review highlights the evidence for ACT to improve general medical outcomes, reduce treatment costs, and increase access to treatment. METHODS: Using a comprehensive list of relevant search terms, the authors performed a systematic literature database search for articles published through November 2015, resulting in ten articles for inclusion. RESULTS: No studies reported on clinical outcomes of general medical comorbidities or on mortality of ACT clients. Half of the studies reporting utilization (three of six) found a decrease in emergency room usage, and three of four studies identified an increase in outpatient primary care visits. Most studies found no increase in overall medical care costs. Of the few studies reporting on quality of life, most found mild to moderate improvements. CONCLUSIONS: To date, rigorous scientific examination of the effect of ACT on the general health of the populations it serves has not been undertaken. Given ACT's similarity to emerging chronic illness medical management models, the approach seems like a natural fit for improving general medical outcomes of persons with severe mental illnesses. More research is needed that investigates the current effect of ACT teams on general medical outcomes, treatment costs, and access to care.

RESUMEN

BACKGROUND AND PURPOSE: Elevated heart rate (HR) is associated with worse outcomes in patients with cardiovascular disease. Its predictive value in acute stroke patients is less well established. We investigated the effects of HR on admission in acute ischaemic stroke patients. METHODS: Using the Virtual International Stroke Trials Archive (VISTA) database, the association between HR in acute stroke patients without atrial fibrillation and the pre-defined composite end-point of (recurrent) ischaemic stroke, transient ischaemic attack (TIA), myocardial infarction (MI) and vascular death within 90 days was analysed. Pre-defined secondary outcomes were the composite end-point components and any death, decompensated heart failure and degree of functional dependence according to the modified Rankin Scale after 90 days. HR was analysed as a categorical variable (quartiles). RESULTS: In all, 5606 patients were available for analysis (mean National Institutes of Health Stroke Scale 13; mean age 67 years; mean HR 77 bpm; 44% female) amongst whom the composite end-point occurred in 620 patients (11.1%). Higher HR was not associated with the composite end-point. The frequencies of secondary outcomes were 3.2% recurrent stroke (n = 179), 0.6% TIA (n = 35), 1.8% MI (n = 100), 6.8% vascular death (n = 384), 15.0% any death (n = 841) and 2.2% decompensated heart failure (n = 124). Patients in the highest quartile (HR> 86 bpm) were at increased risk for any death [adjusted hazard ratio (95% confidence interval) 1.40 (1.11-1.75)], decompensated heart failure [adjusted hazard ratio 2.20 (1.11-4.37)] and worse modified Rankin Scale [adjusted odds ratio 1.29 (1.14-1.52)]. CONCLUSIONS: In acute stroke patients, higher HR (>86 bpm) is linked to mortality, heart failure and higher degree of dependence after 90 days but not to recurrent stroke, TIA or MI.

RESUMEN

BACKGROUND: Tissue hypoxia is a cardinal feature of inflammatory diseases and modulates monocyte function. Nitric oxide is a crucial component of the immune cell response. This study explored the metabolism of the endogenous inhibitor of nitric oxide production asymmetric dimethylarginine(ADMA) by monocyte dimethylarginine dimethylaminohydrolase 2(DDAH2), and the role of this pathway in the regulation of the cellular response and the local environment during hypoxia. METHODS: Peritoneal macrophages were isolated from a macrophage-specific DDAH2 knockout mouse that we developed and compared with appropriate controls. Cells were exposed to 3% oxygen followed by reoxygenation at 21%. Healthy volunteers underwent an 8 h exposure to normobaric hypoxia with an inspired oxygen percentage of 12%. Peripheral blood mononuclear cells were isolated from blood samples taken before and at the end of this exposure. RESULTS: Intracellular nitrate plus nitrite(NOx) concentration was higher in wild-type murine monocytes after hypoxia and reoxygenation than in normoxia-treated cells (mean(SD) 13·2(2·4) vs 8·1(1·7) pmols/mg protein, p = 0·009). DDAH2 protein was 4·5-fold (SD 1·3) higher than in control cells (p = 0·03). This increase led to a 24% reduction in ADMA concentration, 0·33(0.04) pmols/mg to 0·24(0·03), p = 0·002). DDAH2-deficient murine monocytes demonstrated no increase in nitric oxide production after hypoxic challenge. These findings were recapitulated in a human observational study. Mean plasma NOx concentration was elevated after hypoxic exposure (3·6(1.8)µM vs 6·4(3·2), p = 0·01), which was associated with a reduction in intracellular ADMA in paired samples from 3·6(0.27) pmols/mg protein to 3·15(0·3) (p < 0·01). This finding was associated with a 1·9-fold(0·6) increase in DDAH2 expression over baseline(p = 0·03). DISCUSSION: This study shows that in both human and murine models of acute hypoxia, increased DDAH2 expression mediates a reduction in intracellular ADMA concentration which in turn leads to elevated nitric oxide concentrations both within the cell and in the local environment. Cells deficient in DDAH2 were unable to mount this response.

RESUMEN

OBJECTIVE: The primary aim of this study was to compare the impact of NAVIGATE, a comprehensive, multidisciplinary, team-based treatment approach for first-episode psychosis designed for implementation in the U.S. health care system, with community care on quality of life. METHOD: Thirty-four clinics in 21 states were randomly assigned to NAVIGATE or community care. Diagnosis, duration of untreated psychosis, and clinical outcomes were assessed via live, two-way video by remote, centralized raters masked to study design and treatment. Participants (mean age, 23) with schizophrenia and related disorders and ≤6 months of antipsychotic treatment (N=404) were enrolled and followed for ≥2 years. The primary outcome was the total score of the Heinrichs-Carpenter Quality of Life Scale, a measure that includes sense of purpose, motivation, emotional and social interactions, role functioning, and engagement in regular activities. RESULTS: The 223 recipients of NAVIGATE remained in treatment longer, experienced greater improvement in quality of life and psychopathology, and experienced greater involvement in work and school compared with 181 participants in community care. The median duration of untreated psychosis was 74 weeks. NAVIGATE participants with duration of untreated psychosis of <74 weeks had greater improvement in quality of life and psychopathology compared with those with longer duration of untreated psychosis and those in community care. Rates of hospitalization were relatively low compared with other first-episode psychosis clinical trials and did not differ between groups. CONCLUSIONS: Comprehensive care for first-episode psychosis can be implemented in U.S. community clinics and improves functional and clinical outcomes. Effects are more pronounced for those with shorter duration of untreated psychosis.

RESUMEN

A preponderance of females develop autoimmune disease, including juvenile idiopathic arthritis (JIA), yet the reason for this bias remains elusive. Evidence suggests that genetic risk of disease may be influenced by sex. PTPN22 rs2476601 is associated with JIA and numerous other autoimmune diseases, and has been reported to show female-specific association with type 1 diabetes. We performed main effect and sex-stratified association analyses to determine whether a sex-specific association exists in JIA. As expected, rs2476601 was associated with JIA in our discovery (413 cases and 690 controls) and replication (1008 cases and 9284 controls) samples. Discovery sample sex-stratified analyses demonstrated an association specifically in females (odds ratio (OR)=2.35, 95% confidence interval (CI)=1.52-3.63, P=0.00011) but not males (OR=0.91, 95% CI=0.52-1.60, P=0.75). This was similarly observed in the replication sample. There was evidence for genotype-by-sex interaction (Pinteraction=0.009). The association between rs2476601 and JIA appears restricted to females, partly accounting for the predominance of females with this disease.

RESUMEN

This mixed-methods pilot study examined the feasibility, acceptability, and impact of a web-based gratitude exercise (the 'Three Good Things' exercise (TGT)) among 23 adults in outpatient treatment for alcohol use disorder (AUD). Participants were randomized to TGT or a placebo condition. The intervention was feasible with high rates of completion. Participants found TGT acceptable and welcomed the structure of daily emails; however, they found it difficult at times and discontinued TGT when the study ended. Participants associated TGT with gratitude, although there were no observed changes in grateful disposition over time. TGT had a significant effect on decreasing negative affect and increasing unactivated (e.g., feeling calm, at ease) positive affect, although there were no differences between groups at the 8 week follow up. Qualitative results converged on quantitative findings that TGT was convenient, feasible, and acceptable, and additionally suggested that TGT was beneficial for engendering positive cognitions and reinforcing recovery.
