RESUMO

Background: Preliminary evidence suggests that classic psychedelics may be effective in the treatment of some psychiatric disorders, yet little remains known about their effects on health behavior and physical health. Objectives: The purpose of this study was to investigate associations of lifetime classic psychedelic use and psychological insight during one's most insightful classic psychedelic experience with health behavior and physical health. Methods: Using data representative of the US population with regard to sex, age, and ethnicity (N = 2822), this study examined associations of lifetime classic psychedelic use and psychological insight with health behavior and physical health. Results: Lifetime classic psychedelic use was associated with more healthy tobacco-related and diet-related behavior (ß = 0.05 and 0.09, respectively). Among lifetime classic psychedelic users (n = 613), greater Psychological Insight Questionnaire (PIQ) total scale, PIQ Avoidance and Maladaptive Patterns (AMP) subscale, and PIQ Goals and Adaptive Patterns (GAP) subscale scores were each associated with higher odds of more healthy exercise-related behavior [adjusted odds ratios (aOR) (95% confidence interval, CI = 1.38 (1.13-1.68), 1.38 (1.13-1.68), and 1.32 (1.10-1.60), respectively] and higher odds of having a healthy body mass index (BMI) [aOR (95% CI) = 1.32 (1.07-1.63), 1.36 (1.10-1.69), and 1.23 (1.01-1.50), respectively], and greater GAP subscale scores were associated with more healthy diet-related behavior (ß = 0.10). All PIQ scales were positively associated with some health behavior improvements (overall, diet, exercise) attributed to respondents' most insightful classic psychedelic experience (ß = 0.42, 0.18, and 0.17; ß = 0.40, 0.19, and 0.17; and ß = 0.40, 0.15, and 0.15, respectively), but only PIQ total scale and AMP subscale scores were positively associated with alcohol-related health behavior improvements (ß = 0.13 and 0.16, respectively). Conclusion: Although these results cannot demonstrate causality, they suggest that psychological insight during a classic psychedelic experience may lead to positive health behavior change and better physical health in some domains, in particular in those related to weight management.

RESUMO

INTRODUCTION: To date, there are limited real-world studies published on the use of infliximab-dyyb, a biosimilar to reference product (RP) infliximab approved for the treatment of moderate to severe inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC) in North America. This study examined utilization patterns and the effects of infliximab-dyyb on clinical outcomes, patient-reported outcomes (PROs), and healthcare resource use (HCRU) in IBD patients in a real-world setting. METHODS: In this prospective, observational study, adult IBD patients in the US and Canada were recruited to initiate treatment with infliximab-dyyb and followed for 12 months. Patients included biologic-naïve users of infliximab-dyyb and patients switching from RP infliximab or other biologics to infliximab-dyyb. Partial Mayo (pMAYO) and Harvey Bradshaw Index (HBI) scores measured clinical outcomes for the UC and CD cohorts, respectively. Key PRO measures included the SIBDQ, EQ-VAS, and psychological outcomes. In addition, work productivity, HCRU, and adverse events (AEs) were assessed. RESULTS: A total of 67 CD and 48 UC patients were enrolled (51% female; mean age 44 years; 87% Caucasian; mean BMI 27.9). Thirty-nine patients were biologic-naïve, 57 switched from RP infliximab, and 19 switched from other biologics. Among UC biologic-naïve users, pMAYO decreased from 5.67 to 1.09 (p < 0.0001) and the remission rate increased from 5.6 to 90.9% (p = 0.0015). For UC patients switching from RP infliximab, pMAYO decreased from 1.38 to 0.29 (p = 0.0103). For CD biologic-naïve users, HBI scores and remission rates did not significantly change. The scores on all the PROs significantly improved from baseline to 12 months. A total of 22 AEs occurred consistent with the known AE profile for infliximab. CONCLUSIONS: Clinical outcomes among biologic-naïve users of infliximab-dyyb improved for UC and were maintained for CD patients. Biologic-naïve users of infliximab-dyyb showed significant improvements in PROs. Patients switching from RP infliximab to infliximab-dyyb maintained their clinical outcomes and PROs.

RESUMO

BACKGROUND: Invasive mucormycosis (IM) is a rare and often life-threatening fungal infection, for which clinical and epidemiological understanding is lacking. Electronic health record (EHR) data can be utilized to elucidate large populations of patients with IM to address this unmet need. This study aimed to descriptively assess data on patients with IM using the Optum® EHR dataset. METHODS: US patient data from the Optum® deidentified EHR dataset (2007-2019) were analyzed to identify patients with IM. Patients with hematologic malignancies (HM), at high risk of IM, were selected and sorted by IM diagnosis (ICD9 117.7; ICD10 B46). Demographics, comorbidities/other diagnoses, and treatments were analyzed in patients with IM. RESULTS: In total, 1133 patients with HM and IM were identified. Most were between 40 and 64 years of age, Caucasian, and from the Midwest. Essential primary hypertension (50.31%) was the most common comorbidity. Of the 1133 patients, only 33.72% were prescribed an antifungal treatment. The most common antifungal treatments were fluconazole (24.27%) and posaconazole (16.33%), which may have been prophylactic, and any AmB (15.62%). CONCLUSIONS: A large population of patients with IM were identified, highlighting the potential of analyzing EHR data to investigate epidemiology, diagnosis, and the treatment of apparently rare diseases.

RESUMO

INTRODUCTION: Fear of cancer recurrence (FCR) is a common condition among cancer survivors that can lead to significant levels of distress, anxiety and depression. Online mindfulness programmes may provide the mechanism to support cancer survivors manage FCR and distress, and improve people's well-being over the short, medium and long term. The primary aim of this study is to determine the potential efficacy of MindOnLine, a 9 session mindfulness-based programme for survivors of breast, prostate and colorectal cancer. A formal economic programme will also be conducted. METHODS AND ANALYSIS: A single-blind randomised controlled trial to determine the efficacy and cost-efficacy of a MindOnLine programme for cancer survivors. A total of 400 people living with cancer will be recruited via online advertisements on social media platforms, peak consumer advocacy groups or through outpatient services at healthcare providers across Victoria, Australia. People will be randomly allocated to either the MindOnLine programme (n=200) or waitlist control (n=200). Participant assessments will occur at baseline, at 9 weeks and 9-month follow-up. The primary outcome is change in Fear of Recurrence Index Score total score between baseline and 9 weeks; secondary outcomes are changes in depression and anxiety, quality of life and mindfulness. The economic analysis comprises a cost-consequences analysis where all outcomes will be compared with costs. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Peter MacCallum Cancer Centre (20-53) and Deakin University (2020-284). All participants will be required to provide written informed consent. Findings will be disseminated in peer reviewed journals and among key stakeholder organisations including hospitals, cancer and community organisations and Government. If successful the project will be rolled out nationally with a formal implementation plan. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (12620000645954); Pre-results.

RESUMO

INTRODUCTION: Diagnosis and treatment of invasive mold infections (IMI) can be challenging and IMI is a significant source of morbidity and mortality. Invasive aspergillosis (IA) and invasive mucormycosis (IM) are two of the most common mold infections. A better understanding of patient comorbidities and risk factors that predispose IMI may help clinicians to refine the difficult diagnostic and treatment process. METHODS: A systematic literature review (SLR) was conducted (January 2008-October 2019) for studies reporting comorbidities/risk factors of patients with IA or IM (Phase I), followed by an analysis on the Optum® US EHR database of prominent risk factor cohorts based on SLR findings and expert opinion (Phase II). From the four identified patient cohorts: 1) patients undergoing solid organ transplant (SOT) and patients with 2) hematologic cancers, 3) diabetes, or 4) lung disease, rates of IA, IM, or concurrent IA and IM; patient comorbidities; and Charlson Comorbidity Index (CCI) scores were reported. RESULTS: The SLR included 88 studies, and 46 were used to select comorbidities/risk factors cohorts in IA and IM patients. The most important comorbidities/risk factors in IA and IM patients were diabetes, lung disease, hematological malignances, and SOT. In the Optum database (N=101,340,454 patients), IA rates were highest in lung transplant (10.81%) patients and IM rates were highest in intestine transplant (0.83%) patients, lung transplant (0.43%), and hematopoietic stem cell transplant (0.49%). CCI scores were elevated in all mold infection groups compared to the total Optum cohort. CONCLUSION: The current study describes patient comorbidity and risk factors associated with IA and IM. These data can be used to refine clinical decision-making regarding when to suspect mold infections. Future research should focus on identifying whether patients respond differently to various antifungal treatments to determine if strategic recommendations should be made for certain patient groups.

RESUMO

ABSTRACT Background: Early antibiotic switch and early discharge protocols have not been widely studied in Latin America. Our objective was to describe real-world treatment patterns, resource use, and estimate opportunities for early switch from intravenous to oral antibiotics and early discharge for patients hospitalized with methicillin-resistant Staphylococcus aureus complicated skin and soft-tissue infections. Materials/methods: This retrospective medical chart review recruited 72 physicians from Brazil to collect data from patients hospitalized with documented methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections between May 2013 and May 2015, and discharged alive by June 2015. Data collected included clinical characteristics and outcomes, hospital length of stay, methicillin-resistant Staphylococcus aureus-targeted intravenous and oral antibiotic use, and early switch and early discharge eligibility using literature-based and expert-validated criteria. Results: A total of 199 patient charts were reviewed, of which 196 (98.5%) were prescribed methicillin-resistant Staphylococcus aureus -active therapy. Only four patients were switched from intravenous to oral antibiotics while hospitalized. The mean length of methicillin-resistant Staphylococcus aureus-active treatment was 14.7 (standard deviation, 10.1) days, with 14.6 (standard deviation, 10.1) total days of intravenous therapy. The mean length of hospital stay was 22.2 (standard deviation, 23.0) days. The most frequent initial methicillin-resistant Staphylococcus aureus-active therapies were intravenous vancomycin (58.2%), intravenous clindamycin (19.9%), and intravenous daptomycin (6.6%). Thirty-one patients (15.6%) were discharged with methicillin-resistant Staphylococcus aureus -active antibiotics of which 80.6% received oral antibiotics. Sixty-two patients (31.2%) met early switch criteria and potentially could have discontinued intravenous therapy 6.8 (standard deviation, 7.8) days sooner, and 65 patients (32.7%) met early discharge criteria and potentially could have been discharged 5.3 (standard deviation, 7.0) days sooner. Conclusions: Only 2% of patients were switched from intravenous to oral antibiotics in our study while almost one-third were early switch eligible. Additionally, one-third of hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections were early discharge eligible indicating opportunity for reducing intravenous therapy and days of hospital stay. These results provide insight into possible benefits of implementation of early switch/early discharge protocols in Brazil.

RESUMO

PURPOSE: This study assessed the feasibility and acceptability of an online mindfulness-based intervention (MBI) for people diagnosed with melanoma. The potential benefit of the MBI on fear of cancer recurrence (FCR), worry, rumination, perceived stress and trait mindfulness was also explored. METHODS: Participants who have completed treatment for stage 2c or 3 melanoma were recruited from an outpatient clinic and randomly allocated to either the online MBI (intervention) or usual care (control). The 6-week online MBI comprised short videos, daily guided meditations and automated email reminders. Participants were asked to complete questionnaires at baseline and at 6-week post-randomisation. Study feasibility and acceptability were assessed through recruitment rates, retention and participant feedback. Clinical and psychosocial outcomes were compared between groups using linear mixed models. RESULTS: Sixty-nine (58%) eligible participants were randomised (46 in the intervention; 23 in the control group); mean age was 53.4 (SD 13.1); 54% were female. Study completion rate across both arms was 80%. The intervention was found helpful by 72% of the 32 respondents. The intervention significantly reduced the severity of FCR compared to the control group (mean difference = - 2.55; 95% CI - 4.43, - 0.67; p = 0.008). There was no difference between the intervention and control groups on any of the outcome measures. CONCLUSIONS: This online MBI was feasible and acceptable by people at high risk of melanoma recurrence. It significantly reduced FCR severity in this sample. Patients valued accessing the program at their own pace and convenience. This self-guided intervention has the potential to help survivors cope with emotional difficulties. An adequately powered randomised controlled trial to test study findings is warranted.

RESUMO

BACKGROUND: People with a melanoma diagnosis are at risk of recurrence, developing a new primary or experiencing disease progression. Previous studies have suggested that fear of a cancer recurrence is clinically relevant in this group of patients and, if not addressed, can lead to distress. Mindfulness-based interventions have been shown to alleviate symptoms of anxiety and depression among various groups of cancer patients. Online mindfulness-based interventions have the potential to reach people unable to attend face-to-face interventions due to limitations such as cancer-related illness, transportation or time constraints. This study aims to (1) examine whether individuals with a melanoma diagnosis are willing to participate and adhere to a 6-week online mindfulness-based intervention and (2) explore potential benefits of the program on fear of cancer recurrence, worries, rumination, perceived stress and trait mindfulness to inform the design of a clinical trial. METHODS/DESIGN: This is a single-site randomised controlled trial of a feasibility study. Seventy-five participants with stage 2c or 3 melanoma will be recruited from a melanoma outpatient clinic and randomised (2:1) either to an online mindfulness-based program (intervention) or to usual care (control). The intervention is a 6-week program specifically developed for this study. It consists of videos describing the concept of mindfulness, short daily guided meditation practices (5-10 min), automated meditation reminders and instructions for applying mindfulness in daily life to enhance wellbeing. All participants will complete questionnaires at baseline and at 6-week post-randomisation. Participants in the control group will be given access to the online program at the end of the study. Primary outcomes are overall recruitment; retention; extent of questionnaire completion; and usability and acceptability of, and adherence to, the program. The secondary outcomes are fear of cancer recurrence, worries, rumination, perceived stress and trait mindfulness measured using validated instruments. DISCUSSION: This feasibility study will evaluate participants' satisfaction with the program and identify barriers to recruitment and adherence. The recruitment and data collection process will highlight methodological aspects to address in the planning of a larger scale study assessing the impact of an online mindfulness-based intervention on fear of cancer recurrence and wellbeing.

RESUMO

AIM: To explore the knowledge, attitudes, and practices associated with meditation among people with melanoma and investigate the relationship between perceived stress, trait mindfulness, and meditation. Factors associated with interest to participate in an online meditation program were also explored. METHODS: A survey-based cross-sectional study of 291 patients attending a melanoma outpatient clinic assessed knowledge of meditation, attitudes toward meditation using Determinants of Meditation Practice Inventory (DMPI), and meditation experience. Perceived stress and trait mindfulness were measured using the Perceived Stressed Scale and Cognitive and Affective Mindfulness Scale, respectively. RESULTS: Participants who had tried meditation (43%) were likely to be younger, female, and have completed higher education or be employed. Perceived stress score was higher among women, younger participants, and those treated in the past year but did not differ by melanoma stage. Participants reported a good understanding of the potential benefits of meditation, but even among people with meditation experience, common misconceptions prevailed. The main barrier to meditation was a perceived lack of knowledge about meditation . Higher DMPI scores were associated with lower education, moderate to low access to service centers, or living in disadvantaged neighborhoods . Participants practicing meditation that involved self-reflection reported less stress and higher trait mindfulness compared with participants practicing another type of meditation. People interested in participating in an online meditation-based program reported higher perceived stress than those not interested. CONCLUSION: A meditation-based intervention teaching self-reflective practices, targeted at people with melanoma, may have the potential to assist them with managing their stress.

RESUMO

BACKGROUND: Antifungal prophylaxis is a promising strategy for reducing invasive fungal infections (IFIs) in allogeneic hematopoietic cell transplant (alloHCT) recipients, but the optimum prophylactic agent is unknown. We used mixed treatment comparison (MTC) meta-analysis to compare clinical trials examining the use of oral antifungals for prophylaxis in alloHCT recipients, with the goal of informing medical decision-making. METHODS: Randomized controlled trials (RCTs) of fluconazole, itraconazole, posaconazole, and voriconazole for primary antifungal prophylaxis were identified through a systematic literature review. Outcomes of interest (incidence of IFI/invasive aspergillosis/invasive candidiasis, all-cause mortality, and use of other antifungals) were extracted from eligible RCTs and incorporated into a Bayesian hierarchical random-effects MTC. RESULTS: Five eligible RCTs, randomizing 2147 patients in total, were included. Relative to fluconazole, prophylaxis with itraconazole (odds ratio [OR]: 0.52; interquartile range [IQR]: 0.35-0.76), posaconazole (OR: 0.56; IQR: 0.32-0.99), and voriconazole (OR: 0.46; IQR: 0.28-0.73) reduced incidence of overall proven/probable IFI. Posaconazole (OR: 0.31; IQR: 0.17-0.58) and voriconazole (OR: 0.33; IQR: 0.17-0.58) prophylaxis reduced proven/probable invasive aspergillosis more than itraconazole (OR: 0.68; IQR: 0.42-1.12). All-cause mortality was similar across all mould-active agents. CONCLUSION: As expected, mould-active azoles prevented IFIs, particularly invasive aspergillosis, more effectively than fluconazole in alloHCT recipients. The paucity of comparative efficacy data suggests that other factors such as long-term tolerability, availability of intravenous formulations, local IFI epidemiology, and drug costs may need to form the basis for selection among the mould-active azoles.

RESUMO

OBJECTIVE: To measure right and left ventricular function in neonates with congenital diaphragmatic hernia (CDH) and persistent pulmonary hypertension of the newborn (PPHN) before and after surgical repair. METHODS: Ten newborns with CDH and PPHN before and after surgical repair and 24 normal newborns underwent Doppler echocardiographic measurements of the systolic time intervals (STI) and the index of myocardial performance (IMP) or Tei Index to assess pulmonary hypertension and ventricular function, respectively. RESULTS: In newborns with CDH and PPHN before surgical repair, STI pre-ejection time/ejection time ratio and pre-ejection time/acceleration time ratio (0.39 ± 0.19 and 1.22 ± 0.6) were significantly prolonged when compared to newborns with CDH and PPHN after surgical repair (0.21 ± 0.05 and 0.80 ± 0.2) and normal newborns (0.20 ± 0.04 and 0.59 ± 0.2), respectively (all p < 0.001). Left IMP and right IMP were also significantly prolonged in newborns with CDH and PPHN before surgery (0.38 ± 0.16 and 0.53 ± 0.25) when compared to newborns with CDH and PPHN after surgery (0.30 ± 0.07 and 0.28 ± 0.13) and normal newborns (0.26 ± 0.09 and 0.20 ± 0.10), respectively (p < 0.05, left IMP) and (p < 0.001, right IMP). CONCLUSIONS: Significant pulmonary hypertension and abnormal left and right ventricular function were found in newborns with CDH and PPHN before surgical repair when compared to the newborns with CDH and PPHN after surgical repair and normal newborns. The STI and the IMP or Tei index can accurately estimate the consequences of pulmonary hypertension and left and right ventricular function in neonates with CDH and PPHN, which may affect management in these critically ill neonates.

RESUMO

1,3-Ketoesters and 1,3-diketones react with fluorine gas, using Durham multichannel modular microreactor technology, on a preparatively useful scale. High conversions and yields of monofluorinated products were obtained. A consideration of the mechanism of fluorination of dicarbonyl systems provides a rationale of the scope and limitations of the use of microreactor technology for such direct fluorination processes. We conclude that it is especially appropriate for the fluorination of diketones and ketoesters that exist mainly in the enol form at equilibrium and/or undergo rapid keto-enol interconversion. A one-stage route to fluoroketones from ketoesters was achieved by allowing the crude product mixture obtained from the fluorination of the ketoesters to stand for a period of time before reaction work-up.

RESUMO

Versatile and conveniently operated microreactor devices, suitable for long term chemical synthesis for both laboratory and industrial use, are described. Direct fluorination of ethyl acetoacetate by fluorine gas is used as a model reaction to illustrate the successful application of reactors having either 9, 18 or 30 microchannels, with all channels supplied from single reagent sources, to provide significant quantities of fluorinated products. Convenient reactor maintenance, simple design, versatility and the enhanced safety features of using such modular microreactor devices, make these systems appropriate for synthesis on the large scale.

RESUMO

OBJECTIVE: The objective was to estimate the role of abdominal radiographs in the management of the patient with gastrointestinal dysfunction in the early postoperative period following intra-abdominal gynecologic surgery. METHODS: Hospital records were reviewed for 84 patients from the gynecologic oncology service having a clinical diagnosis of either ileus or bowel obstruction immediately after intra-abdominal gynecologic surgery. Patient history, clinical signs and symptoms, findings of plain radiographs, and clinical course were studied to determine whether plain abdominal radiographs were useful in the management of these patients. RESULTS: At least one set of abdominal X-rays was obtained for 56 (66.7%) patients, of which 24 (42.9%) were considered radiographically diagnostic. A lower preoperative American Society of Anesthesiologists (ASA) physical status score correlated with a greater likelihood of having abdominal films (P = 0.005). No single clinical finding correlated with either the decision to obtain films or X-ray diagnosis of ileus or bowel obstruction. Use of any nonsurgical treatment modality was not significantly different for patients who had films versus those who did not. Mean length of hospital stay was significantly prolonged for patients who had abdominal X-rays. Seven patients were subjected to reoperation; however, no association was found between X-ray diagnosis of ileus or bowel obstruction and the need for reoperation. CONCLUSION: Plain abdominal radiographs have little clinical utility in the evaluation of patients with gastrointestinal dysfunction in the early postoperative period following intra-abdominal gynecologic surgery. Diagnostic studies such as CT scanning or a GI contrast study may be more helpful in the management of these patients.

RESUMO

The aim of this prospective study was to evaluate the association of peripheral B-type natriuretic peptide (BNP) levels with clinical symptoms and central hemodynamic and echocardiographic measures in cardiac transplantation. BNP reflects ventricular wall stress and correlates with severity of heart failure. No previous investigation has comprehensively assessed the rapid bedside BNP assay for predicting hemodynamic measures of cardiac allograft function in heart transplantation. We evaluated BNP levels using a rapid point-of-care assay in 87 stable cardiac transplant recipients who had 237 consecutive measurements along with endomyocardial biopsy, right-sided cardiac catheterization, and echocardiography. Using median tendencies, 2 groups were identified: the low BNP group (n = 116, BNP <150 pg/ml) and the high BNP group (n = 121, BNP >/=150 pg/ml). The high BNP group had increased right atrial pressures, higher pulmonary artery systolic pressures, pulmonary capillary wedge pressures, and lower cardiac index. Besides hemodynamic variables, the presence of right ventricular dysfunction (p = 0.05) and significant tricuspid regurgitation (p = 0.003) were associated with higher BNP levels. Independent predictors of BNP levels on multivariate analysis included elevated pulmonary capillary wedge pressure, lower cardiac index, and symptoms of dyspnea and fatigue. This initial investigation establishes the accuracy of a point-of-care BNP assay in predicting cardiopulmonary hemodynamic aberrations despite preserved left ventricular systolic function in heart transplant recipients. Rapid bedside BNP analysis may provide a noninvasive surrogate method for the comprehensive assessment of cardiac allograft function and hemodynamics in heart transplantation.
