RESUMEN

OBJECTIVE: To examine the effect of esketamine nasal spray (ESK) plus newly initiated oral antidepressant (OAD) versus OAD plus placebo nasal spray (PBO) on the association between Montgomery-Åsberg Depression Rating Scale (MADRS) and 9-item Patient Health Questionnaire (PHQ-9) scores in adults with treatment-resistant depression (TRD). METHODS: Data from TRANSFORM-1 and TRANSFORM-2 (two similarly designed, randomized, active-controlled TRD studies) and SUSTAIN-1 (relapse prevention study) were analyzed. Group differences for mean changes in PHQ-9 total score from baseline were compared using analysis of covariance. Associations between MADRS and PHQ-9 total scores from TRANSFORM-1/TRANSFORM-2 were assessed using simple parametric, nonparametric, and multiple regression models. RESULTS: In TRANSFORM-1/TRANSFORM-2 (ESK + OAD, n = 343; OAD + PBO, n = 222), baseline PHQ-9 mean scores were 20.4 for ESK + OAD and 20.6 for OAD + PBO (severe depression). At day 28, significant group differences were observed in least squares mean change (SE) in PHQ-9 scores from baseline (-12.8 [0.46] vs -10.3 [0.53], P < .001) and in clinically substantial change in PHQ-9 scores (≥6 points; 77.1% vs 64%, P < .001) in ESK + OAD and OAD + PBO groups, respectively. A nonlinear relationship between MADRS and PHQ-9 was observed; total scores demonstrated increased correlation over time. In SUSTAIN-1, 57.3% of patients receiving ESK + OAD (n = 89) versus 44.2% receiving OAD + PBO (n = 86) retained remission status (PHQ-9 score ≤4) at maintenance treatment end point (P = .044). CONCLUSIONS: In adults with TRD, ESK + OAD significantly improved severity of depressive symptoms, and more patients achieved clinically meaningful changes in depressive symptoms based on PHQ-9, versus OAD + PBO. PHQ-9 outcomes were consistent with those of clinician-rated MADRS. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02417064, NCT02418585, NCT02493868.

RESUMEN

Recent event-related potential (ERP) studies in language comprehension converge in finding anticipatory negativities preceding words or word segments that can be pre-activated based on either sentence contexts or phonological cues. We review these findings from different paradigms in the light of evidence from other cognitive domains in which slow negative potentials have long been associated with anticipatory processes and discuss their potential underlying mechanisms. We propose that this family of anticipatory negativities captures common mechanisms associated with the pre-activation of linguistic information both within words and within sentences. Future studies could utilize these anticipatory negativities in combination with other, well-established ERPs, to simultaneously track prediction-related processes emerging at different time intervals (before and after the perception of pre-activated input) and with distinct time courses (shorter-lived and longer-lived cognitive operations).

RESUMEN

AIM: To provide a comprehensive and more representative national data on the disease, especially on treatment options and outcomes, and to determine access of retinoblastoma patients from Luzon, Visayas and Mindanao to eye care, and determine if access is associated with delay in consultation, staging and outcomes. METHODS: Cohort study of retinoblastoma patients seen in eleven institutions located in the three major areas of the Philippines namely Luzon, Vizayas and Mindanao from 2010-2020. RESULTS: Totally 636 patients, involving 821 eyes, were included. Majority (57%) were from Luzon and were seen in institutions in Luzon (72%). Annually, 58±10 new cases were seen with 71% having unilateral disease. Median delay of consultation remained long at 9 (3, 17)mo, longest in patients with unilateral disease (P<0.02) and those from the Visayas (P<0.003). Based on the International Retinoblastoma Staging System, only 35% of patients had Stage 1 while 47% already had extraocular disease. Enucleation was the most common treatment received by 484 patients while intravenous chemotherapy was received by 469. There were 250 (39%) patients alive, 195 (31%) dead, 85 (13%) abandoned, 17 (3%) refused and 89 (14%) with no data. CONCLUSION: This study presents the largest cohort of retinoblastoma patients in the Philippines in terms of patients' and participating institutions' number and geographical location and type of institution (private and public). It also presents more comprehensive data on the treatments used and outcomes (survival, globe salvage, and vision retention rates). Delay in consultation was still long among patients leading to advanced disease stage and lower survival rate. Despite increasing capacity to diagnose and manage retinoblastoma in the country, the delay of consultation remains long primarily due to accessibility issues to eye care institutions especially in the Visayas and financial concerns. The delay was still significant that overall survival rate remain low.

RESUMEN

BACKGROUND: Treatment-resistant depression (TRD) is a chronic illness requiring long-term treatment. Esketamine nasal spray (ESK) has been studied in several long-term trials of patients with TRD, including SUSTAIN-1 (NCT02493868) and SUSTAIN-3 (NCT02782104). This subgroup analysis of SUSTAIN-3 evaluated patients with TRD who received a second induction (IND) and maintenance treatment with ESK plus oral antidepressant (AD) after a relapse in SUSTAIN-1. METHODS: Patients aged 18-64 years who achieved stable remission or response with ESK and subsequently relapsed after randomization to continue ESK or switch to placebo nasal spray (PBO) in SUSTAIN-1 and entered the IND phase of SUSTAIN-3 were included in this interim analysis. Response (≥50% improvement in total score from baseline for Montgomery-Åsberg Depression Rating Scale [MADRS] and Patient Health Questionnaire 9-item [PHQ-9]), remission (MADRS score ≤12; PHQ-9 total score <5), changes in depression rating scores (measured as mean change from baseline), and safety were evaluated (incidence of treatment-emergent and serious adverse events [AE]). RESULTS: Of the 96 eligible patients who entered IND in SUSTAIN-3, 32 (33.3%) were taking ESK+AD at the time of relapse in SUSTAIN-1 and 64 (66.7%) were taking AD+PBO. Substantial improvements in depressive symptoms were observed over the second IND phase in both groups and were maintained over the optimization/maintenance (OP/M) phase. MADRS response rates following a second IND were 71.9% and 73.4% for previously relapsed (PR) ESK+AD and PR-AD+PBO, respectively; remission rates were 62.5% and 60.9%, respectively. During the IND and OP/M phases, 58.3% and 83.3% of patients experienced a treatment-emergent AE, respectively. No patients discontinued due to an AE during the second IND. CONCLUSIONS: Patients with TRD benefitted from receiving a second IND and maintenance treatment with ESK and no new safety signals were identified.

RESUMEN

PURPOSE: The purpose of this study was to examine the effects of psychological capital on the relationship between physical violence and mental health issues of nurses and personal care assistants (PCAs) working in aged care using the job demands-resources theory. METHODOLOGY: Data were collected from 254 nurses and PCAs of the Australian Nursing Midwifery Federation located in Victoria, Australia. The study takes a quantitative approach and tests the hypotheses through regression analyses. FINDINGS: The results indicate that experiencing physical violence increases levels of stress, depression, and anxiety. This, in turn, increases nurses' and PCAs' intention to leave. However, increased psychological capital can assist nurses and PCAs in dealing with physical violence. RESEARCH IMPLICATIONS: The study acknowledges that physical violence is a factor in nurses' intention to leave. The significant finding is that psychological capital plays a protective role in ameliorating the negative impact of physical violence on individual well-being and intentions to leave. We note, however, that this is a cross-section study, and more longitudinal research needs to be undertaken. PRACTICAL IMPLICATIONS: There are clear implications for managers to create a supportive organization that cultivates hope, self-efficacy, and resilience, thereby increasing psychological capital. Leadership development programs could build a supportive foundation for nurses to seek support and build resilience. Job construction should be focused on protecting nurses from risk by utilizing manageable workloads to limit stress, depression, and anxiety. ORIGINALITY: Our study extends research on retention of these skilled and important health care workers in a demanding environment that has largely been absent from the literature. Specifically, physical violence is often considered part of nursing work, but its impact on mental health, well-being, and intention to leave are underexplored in this sector, as well as the effectiveness of specific measures that bolster the negative impact of physical violence on nurses.

RESUMEN

INTRODUCTION: Treatment resistant depression (TRD) is one of the most pressing issues in mental healthcare in LatAm. However, clinical data and outcomes of standard of care (SOC) are scarce. The present study reported on the Treatment-Resistant Depression in America Latina (TRAL) project 1-year follow-up of patients under SOC assessing clinical presentation and outcomes. MATERIALS AND METHODS: 420 patients with clinical diagnoses of TRD from Argentina, Brazil, Colombia and Mexico were included in a 1-year follow-up to assess clinical outcomes of depression (MADRS) and suicidality (C-SSRS), as well as evolution of clinical symptoms of depression. Patients were assessed every 3 months and longitudinal comparison was performed based on change from baseline to each visit and end of study (12 months). Socio demographic characterization was also performed. RESULTS: Most patients were female (80.9%), married (42.5%) or single (34.4%), with at least 10 years of formal education (71%). MDD diagnosis was set at 37.29 (SD=14.00) years, and MDD duration was 11.11 years (SD=10.34). After 1-year of SOC, 79.1% of the patients were still symptomatic, and 40% of the patients displayed moderate/severe depression. Only 44.1% of the patients achieved a response (≥50% improvement in MADRS), and 60% of the sample failed to achieve remission. Suicidal ideation was reported by more than half of the patients at the end of study. CONCLUSIONS: Depression and suicidality symptoms after a 1-year of SOC is of great concern. Better therapeutic options are needed to tackle this debilitating and burdensome disease.

RESUMEN

This study examines social determinants impacting the health and wellbeing of Aboriginal and Torres Strait Islander men in Australia. Social determinants prevent many men from thriving in community environments which also impacts on their social, work and family lives. We examine the impact on men's health and identify how men who participate in Men's Sheds/groups engage in learning about health interventions. Our study extends the work of Percival et al. and their Indigenous health promotion model. A qualitative case study approach conducted 'gatherings' and 'yarning circles' (focus groups) with men from urban, regional and remote areas of the country. We argue that men's groups can serve as a central intervention to support men to build their confidence to learn about health and wellbeing and how to thrive through activities in community life. Findings support health interventions delivered through training and mentoring around various health and other services, healthy eating, sport and fathering programmes (to name a few) to enhance awareness and men's vitality for learning. There are implications for our healthcare system to better understand the conditions of Aboriginal men's health and support these vulnerable groups. Our study proposes men's groups as culturally safe environments to promote and deliver central health promotion interventions that support men to thrive in all facets of their lives.

RESUMEN

To compare the effectiveness at ten years of follow-up of radical prostatectomy, brachytherapy and external radiotherapy, in terms of overall survival, prostate cancer-specific mortality and biochemical recurrence. Cohort of men diagnosed with localized prostate cancer (T1/T2 and low/intermediate risk) from ten Spanish hospitals, followed for 10 years. The treatment selection was decided jointly by patients and physicians. Of 704 participants, 192 were treated with open radical retropubic prostatectomy, 317 with 125I brachytherapy alone, and 195 with 3D external beam radiation. We evaluated overall survival, prostate cancer-specific mortality, and biochemical recurrence. Kaplan-Meier estimators were plotted, and Cox proportional-hazards regression models were constructed to estimate hazard ratios (HR), adjusted by propensity scores. Of the 704 participants, 542 patients were alive ten years after treatment, and a total of 13 patients have been lost during follow-up. After adjusting by propensity score and Gleason score, brachytherapy and external radiotherapy were not associated with decreased 10-year overall survival (aHR = 1.36, p = 0.292 and aHR = 1.44, p = 0.222), but presented higher biochemical recurrence (aHR = 1.93, p = 0.004 and aHR = 2.56, p < 0.001) than radical prostatectomy at ten years of follow-up. Higher prostate cancer-specific mortality was also observed in external radiotherapy (aHR = 9.37, p = 0.015). Novel long-term results are provided on the effectiveness of brachytherapy to control localized prostate cancer ten years after treatment, compared to radical prostatectomy and external radiotherapy, presenting high overall survival, similarly to radical prostatectomy, but higher risk of biochemical progression. These findings provide valuable information to facilitate shared clinical decision-making.Study identifier at ClinicalTrials.gov: NCT01492751.

RESUMEN

OBJECTIVE: Derive and confirm factor structure of the Montgomery-Åsberg Depression Rating Scale (MADRS) in patients with treatment-resistant depression (TRD) and evaluate how the factors evident at baseline change over 4 weeks of esketamine treatment. METHODS: Two similarly-designed, short-term TRANSFORM trials randomized adults to esketamine or matching placebo nasal spray, each with a newly-initiated oral antidepressant, for 4 weeks (TRANSFORM-1: N = 342 patients; TRANSFORM-2: N = 223 patients). The factor structure of MADRS item scores at baseline was determined by exploratory factor analysis in TRANSFORM-2 and corroborated by confirmatory factor analysis in TRANSFORM-1. Change in MADRS factor scores from baseline (day 1) to the end of the 28-day double-blind treatment phase of TRANSFORM-2 was analyzed using a mixed-effects model for repeated measures (MMRM). RESULTS: Three factors were identified based on analysis of MADRS items: Factor 1 labeled affective and anhedonic symptoms (apparent sadness, reported sadness, lassitude, inability to feel), Factor 2 labeled anxiety and vegetative symptoms (inner tension, reduced sleep, reduced appetite, concentration difficulties), and Factor 3 labeled hopelessness (pessimistic thoughts, suicidal thoughts). The three-factor structure observed in TRANSFORM-2 was verified in TRANSFORM-1. Treatment benefit at 24 h with esketamine versus placebo was observed on all 3 factors and continued throughout the 4-week double-blind treatment period. CONCLUSIONS: A three-factor structure for MADRS appears to generalize to TRD. All three factors improved over 4 weeks of treatment with esketamine nasal spray.

RESUMEN

Alpha and beta power decreases have been associated with prediction in a variety of cognitive domains. Recent studies in sentence comprehension have also reported alpha and/or beta power decreases preceding contextually predictable words, albeit with remarkable spatiotemporal variability across reports. To contribute to the understanding of the mechanisms underlying this phenomenon, and the sources of variability, the present study explored to what extent these prediction-related alpha and beta power decreases might be common across different modalities of comprehension. To address this, we re-analysed the data of two EEG experiments that employed the same materials in written and in spoken comprehension. Sentence contexts were weakly or strongly constraining about a sentence-final word, which was presented after a 1 s delay, either matching or mismatching the expectation. In written comprehension, alpha power (8-12 Hz) decreased before final words appearing in strongly (relative to weakly) constraining contexts, in line with previous reports. Furthermore, a similar oscillatory phenomenon was evidenced in spoken comprehension, although with relevant spatiotemporal differences. Altogether, the findings agree with the involvement of both modality-specific and general-domain mechanisms in the elicitation of prediction-related alpha power decreases in sentence comprehension. Specifically, we propose that this phenomenon might partly reflect richer and more precise information representation when linguistic contexts afford prediction.

RESUMEN

Treatment-Resistant Depression (TRD) prevalence varies considerable between regions and epidemiology of TRD in Argentina is lacking. Based on the Treatment-Resistant Depression in America Latina (TRAL) study, epidemiology and burden of TRD in MDD patients from Argentina is reported in this paper. A sample of adult MDD patients (n=396) from 5 sites in Argentina, with clinical diagnosis were included. Patients with psychosis, schizophrenia, bipolar disorder, schizoaffective disorder, dementia, with severe chemical dependence or currently participating in another clinical trial were excluded. Patient reported outcomes and clinical assessment scales were used as outcomes. The prevalence of TRD in MDD patients in Argentina is 33.2%, based on TRAL data. Patients in TRD are older compared to those without TRD, and was more evident in married/consensual union MDD patients. Higher suicidality, greater comorbidity based on MINI, and worse scores in MADRS and PHQ-9 were identified in TRD patients. The prevalence identified in TRAL study for Argentina is substantial comparing with other Latin American countries and worldwide prevalence. TRD represents a disproportional burden to society, and efforts should be placed on reducing the burden of MDD and TRD in Argentina by improving early diagnosis, therapeutic management and ensuring that all patients have better access to mental healthcare.

RESUMEN

Background: A large proportion of patients with major depressive disorder (MDD) have treatment-resistant depression (TRD). The TRAL study examines the impact of TRD on suicidality and health-related quality of life (HRQoL) among MDD patients in 4 Latin American countries. Methods: In this multicenter, prospective, observational study, MDD patients were recruited from 33 sites in Mexico, Colombia, Brazil, and Argentina. Patients were assessed for TRD, defined as failure to respond to ≥2 antidepressant medications of adequate dose and duration. Other assessments included current disease status, Mini International Neuropsychiatric Interview (MINI), Columbia-Suicide Severity Rating Scale (C-SSRS), 5 Level EQ-5D (EQ-5D-5L), Patient Health Questionnaire-9 (PHQ-9), and Sheehan Disability Scale (SDS). Results: 1,475 MDD patients were included in the analysis (mean age, 45.6 years; 78% women), and 429 met criteria for TRD. Thoughts of suicide and suicide attempts were more common among TRD patients (38.7%) compared with non-TRD patients (24.9%; P < 0.0001), according to the current disease status questionnaire. The C-SSRS showed that lifetime suicidal behavior was significantly more common among TRD patients than non-TRD patients (13.8 vs. 10.0%; P = 0.0384). Compared with non-TRD patients, TRD patients showed significantly greater adverse impacts on QoL (EQ-5D-5L), more severe depression (PHQ-9), and greater functional impairment (SDS). Conclusion: TRD patients in clinical sites from Mexico, Colombia, Brazil, and Argentina were more likely to experience suicidality and negative effects on HRQoL than non-TRD patients.

RESUMEN

OBJECTIVES: This study aimed to develop mapping algorithms from the Expanded Prostate Cancer Index Composite (EPIC) and the Short-Form (SF) Health Surveys to the Patient-Oriented Prostate Utility Scale (PORPUS), an econometric instrument specifically developed for patients with prostate cancer. METHODS: Data were drawn from 2 cohorts concurrently administering PORPUS, EPIC-50, and SF-36v2. The development cohort included patients who had received a diagnosis of localized or locally advanced prostate cancer from 2017 to 2019. The validation cohort included men who had received a diagnosis of localized prostate cancer from 2014 to 2016. Linear regression models were constructed with ln(1 - PORPUS utility) as the dependent variable and scores from the original and brief versions of the EPIC and SF as independent variables. The predictive capacity of mapping models constructed with all possible combinations of these 2 instruments was assessed through the proportion of variance explained (R2) and the agreement between predicted and observed values. Validation was based on the comparison between estimated and observed utility values in the validation cohort. RESULTS: Models constructed with EPIC-50 with and without SF yielded the highest predictive capacity (R2 = 0.884, 0.871, and 0.842) in comparison with models constructed with EPIC-26 (R2 = 0.844, 0.827, and 0.776). The intraclass correlation coefficient was excellent in the 4 models (>0.9) with EPIC and SF. In the validation cohort, predicted PORPUS utilities were slightly higher than those observed, but differences were not statistically significant. CONCLUSIONS: Mapping algorithms from both the original and the abbreviated versions of the EPIC and the SF Health Surveys allow estimating PORPUS utilities for economic evaluations with cost-utility analyses in patients with prostate cancer.

RESUMEN

Approximately one-third of patients with major depressive disorder (MDD) have treatment-resistant depression (TRD). The TRAL study will evaluate the prevalence and impact of TRD among patients with MDD in four Latin American countries. In this multicenter, prospective, observational study, patients with MDD were recruited from 33 reference sites in Mexico, Colombia, Brazil, and Argentina. Patients were assessed for TRD, defined as failure to respond to ≥ 2 antidepressant medications of adequate dose and duration. Demographics, previous/current treatments, depressive symptoms, functioning, healthcare resource utilization, and work impairment were also collected and evaluated using descriptive statistics, chi-square test, Fisher exact test, t-test for independent samples, or the Mann-Whitney nonparametric test, as appropriate. 1475 patients with MDD were included in the analysis (mean age, 45.6 years; 78% women); 89% were receiving relevant psychiatric treatment. 429 patients met criteria for TRD, and a numerically higher proportion of patients with TRD was present in public versus private sites of care (31% vs 27%). The mean Montgomery-Asberg Depression Rating Scale score was 25.0 among all MDD patients and was significantly higher for patients with TRD versus non-TRD (29.4 vs 23.3; P < 0.0001). Patients with TRD, versus those with non-TRD, were significantly more likely to be older, have a longer disease duration, have more comorbidities, be symptomatic, have a higher median number of psychiatric consultations, and report greater work impairment. Patients with TRD have a disproportionate burden of disease compared to those with non-TRD. Appropriate treatment for TRD is a substantial unmet need in Latin America. https://www.ClinicalTrials.gov identifier NCT03207282, 07/02/2017.

RESUMEN

The endangered Galapagos sea lion (GSL, Zalophus wollebaeki) exhibits a range of foraging strategies utilising various dive types including benthic, epipelagic and mesopelagic dives. In the present study, potential prey captures (PPC), prey energy consumption and energy expenditure in lactating adult female GSLs (n = 9) were examined to determine their foraging efficiency relative to the foraging strategy used. Individuals displayed four dive types: (a) epipelagic (<100 m; EP); or (b) mesopelagic (>100 m; MP) with a characteristic V-shape or U-shape diving profile; and (c) shallow benthic (<100 m; SB) or (d) deep benthic (>100 m; DB) with square or flat-bottom dive profiles. These dive types varied in the number of PPC, assumed prey types, and the energy expended. Prey items and their energetic value were assumed from previous GSL diet studies in combination with common habitat and depth ranges of the prey. In comparison to pelagic dives occurring at similar depths, when diving benthically, GSLs had both higher prey energy consumption and foraging energy expenditure whereas PPC rate was lower. Foraging efficiency varied across dive types, with benthic dives being more profitable than pelagic dives. Three foraging trip strategies were identified and varied relative to prey energy consumed, energy expended, and dive behaviour. Foraging efficiency did not significantly vary among the foraging trip strategies suggesting that, while individuals may diverge into different foraging habitats, they are optimal within them. These findings indicate that these three strategies will have different sensitivities to habitat-specific fluctuations due to environmental change.

RESUMEN

Cognitive deficits are common in Parkinson's disease (PD), with some PD patients meeting criteria for mild cognitive impairment (MCI). An unaddressed question is whether linguistic prediction is preserved in PD. This ability is nowadays deemed crucial for achieving fast and efficient comprehension, and it may be negatively impacted by cognitive deterioration in PD. To fill this gap of knowledge, we used event-related potentials (ERPs) to evaluate mechanisms of linguistic prediction in a sample of PD patients (on dopamine compensation) with and without MCI. To this end, participants read sentence contexts that were predictive or not about a sentence-final word. The final word appeared after one sec, matching or mismatching the prediction. The introduction of the interval allowed to capture neural responses both before and after sentence-final words, reflecting semantic anticipation and semantic processing. PD patients with normal cognition (N = 58) showed ERP responses comparable to those of matched controls. Specifically, in predictive contexts, a slow negative potential developed prior to sentence-final words, reflecting semantic anticipation. Later, expected words elicited reduced N400 responses (compared to unexpected words), indicating facilitated semantic processing. PD patients with MCI (N = 20) showed, in addition, a prolongation of the N400 congruency effect (compared to matched PD patients without MCI), indicating that further cognitive decline impacts semantic processing. Finally, lower verbal fluency scores correlated with prolonged N400 congruency effects and with reduced pre-word differences in all PD patients (N = 78). This relevantly points to a role of deficits in temporal-dependent mechanisms in PD, besides prototypical frontal dysfunction, in altered semantic anticipation and semantic processing during sentence comprehension.

RESUMEN

Workplace health promotion (WHP) and the general wellbeing of workers in the Australian workforce should be a priority for all management. Our study argues that management support for workers with an intellectual disability (WWID) can make a difference to their health promotion and ultimately their participation in the workforce. We adopt a qualitative approach, through semi-structured interviews with 22 managers, across various organizations, to examine their perspectives around the WHP of WWID. We integrate the key values of WHP; rights for health, empowerment for health and participation for health (Spencer, Corbin and Miedema, Sustainable development goals for health promotion: a critical frame analysis, Health Promot Int 2019;34:847-58) into the four phases of WHP interventions; needs assessment, planning, implementation and evaluation (Bortz and Döring, Research Methods and Evaluation for Human and Social Scientists, Heidelberg: Springer, 2006) and examine management perspectives (setting-based approach) on WHP of WWID. Where this integration had taken place, we found some evidence of managers adopting more flexible, innovative and creative approaches to supporting the health promotion of WWID. This integration seemed to drive continuous improvement for WWID health promotion at the workplace. We also found evidence that some organizations, such an exemplar film company, even over deliver in terms of supporting WWID needs by encouraging their capabilities in film making interventions, whilst others are more direct in their support by matching skills to routine jobs. Our approach demonstrates that incorporating key WHP values into the four-phase WHP framework is critical for the effective health promotion of WWID.

RESUMEN

PURPOSE: Long-term comparative effectiveness research on localized prostate cancer treatments is scarce, and evidence is lacking especially for brachytherapy. The aim of this study was to assess the long-term impact of the side effects of radical prostatectomy, brachytherapy, and external radiation therapy on patients with localized prostate cancer at 10 years, using propensity score analyses. METHODS AND MATERIALS: This was a prospective observational study of a cohort of men who received a diagnosis of clinically localized prostate cancer (clinical stage T1 or T2, low and intermediate risk group) and were treated with radical prostatectomy (n = 139), brachytherapy (n = 317), or external radiation therapy (n = 194). Treatment decisions were jointly made by patients and physicians. Patient-reported outcome (PRO) evaluation included the Expanded Prostate Cancer Index Composite and Short Form-36, administered centrally by telephone interviews before and annually after treatment. The Expanded Prostate Cancer Index Composite covers urinary, bowel, sexual, and hormonal domains. To assess PRO changes over time, while accounting for correlation among repeated measures, generalized estimating equation models adjusted by propensity scores were constructed. RESULTS: The PRO completion rate at 10 years was 85.8%. Generalized estimating equation models showed that the pattern of radical prostatectomy side effects, with substantial urinary incontinence and sexual dysfunction, remained until 10 years after treatment (standard deviation [SD], -1.1 and -1.3, respectively). Brachytherapy produced late deterioration in urinary continence (SD, -0.4) and sexual function (SD, -0.9) that appeared midterm, but the differences from radical prostatectomy remained statistically significant at 10 years (P < .001 after adjusting by propensity score). External radiation therapy showed similar results to brachytherapy, but with bowel bother (SD, -0.3). CONCLUSIONS: Although late deterioration in radiation therapy groups attenuated differences from radical prostatectomy, relevant PRO differences still remained after 10 years. Our findings support that brachytherapy is the treatment option that causes the least impact on PROs; it is therefore an alternative to be considered when making evidence-based decisions on localized prostate cancer treatment.

RESUMEN

Objetivos: A epidemiologia da depressão resistente ao tratamento (DRT) varia mundialmente, mas é incerta na América Latina. Este artigo relata a epidemiologia e o ônus da DRT em pacientes com transtorno depressivo maior (TDM) no Brasil, no estudo observacional multinacional, multicêntrico, de DRT na América Latina (TRAL). Métodos: Trezentos e noventa e seis pacientes adultos com TDM (tratados ou não) no Brasil, com diagnóstico de TDM usando o Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) e confirmado por MINI Entrevista Neuropsiquiátrica Internacional v7.0.2, foram incluídos em 10 centros. Os pacientes forneceram consentimento e concluíram as avaliações. Os critérios de exclusão incluíram pacientes com psicose, esquizofrenia, transtorno bipolar, transtorno esquizoafetivo, demência, transtorno de uso de substância ou participação atual em outro estudo. A MADRS foi usada para gravidade da doença. Escalas de depressão e instrumentos classificados pelos pacientes foram usados para medir os resultados. Resultados: A prevalência de DRT em pacientes com TDM na América Latina corresponde a 29,1% (IC 95% [26,8%; 31,4%]), embora no Brasil corresponda a 40,4% (IC 95%: 35,6%-45,2%), a mais alta no estudo TRAL. Os pacientes com DRT são mais velhos e apresentam maior proporção de divórcios e menor nível educacional, com pontuação mais alta na Escala de Classificação da Depressão de Montgomery-Asberg (MADRS), comparados a pacientes sem DRT. Os custos de saúde foram maiores em pacientes com DRT, com menor qualidade de vida e maiores custos de saúde e comprometimento laboral. Conclusões: Estes achados confirmam que a DRT apresenta alta prevalência no Brasil, consistentemente com estudos anteriores sobre transtornos depressivos. Globalmente, os pacientes com DRT apresentam maior ônus da doença, sugerindo a necessidade de melhorar os cuidados para pacientes com DRT no Brasil


Objectives: Treatment-resistant depression (TRD) epidemiology varies worldwide, but uncertain in Latin America (LatAm). This paper reports on the epidemiology and burden of TRD in major depressive disorder (MDD) patients in Brazil from the TRD in America Latina (TRAL) multicenter, multinational, observational study. Methods: 396 adult patients (treated or untreated) with MDD diagnosis in Brazil using Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) and confirmed by MINI International Neuropsychiatric Interview v7.0.2 were consecutively enrolled from 10 clinical sites in Brazil. Patients provided consent and complete assessments. Exclusion criteria included patients with psychosis, schizophrenia, bipolar disorder, schizoaffective disorder, dementia, with substance use disorder or currently participating in another clinical trial. Montgomery-Asberg Depression Rating Scale (MADRS) was used for disease severity. Depression scales and patient rated instruments were used to measure outcomes. Results: The prevalence of TRD in MDD patients in LatAm is 29.1% (95%CI [26.8%; 31.4%]), though the values for Brazil are 40.4% (95%CI: 35.6%-45.2%), the highest in the TRAL study. TRD patients are older, have higher proportion of divorce and lower education, with higher MADRS score compared to non-TRD patients. Healthcare costs were higher in TRD patients, with lower quality of life (QoL) and higher work impairment and healthcare costs. Conclusions: Present findings confirms that TRD is highly prevalent in Brazil, which is consistent with previous studies concerning depressive disorders. Globally, TRD patients experience higher burden of the disease. These findings suggest the need to improve care among TRD patients in Brazil

RESUMEN

OBJECTIVE: We studied an unusual case of global aphasia (GA) occurring after brain tumor removal and remitting one-month after surgery. After recovering, the patient reported on her experience during the episode, which suggested a partial preservation of language abilities (such as semantic processing) and the presence of inner speech (IS) despite a failure in overt speech production. Thus, we explored the role of IS and preserved language functions in the acute phase and investigated the neuroanatomical underpinnings of this severe breakdown in language processing. METHOD: A neuropsychological and language assessment tapping into language production, comprehension, attention and working memory was carried out both before and three months after surgery. In the acute stage a simplified protocol was tailored to assess the limited language abilities and further explore patient's performance on different semantic tasks. The neuroanatomical dimension of these abrupt changes was provided by perioperative structural neuroimaging. RESULTS: Language and neuropsychological performance were normal/close to normal both before and three months after surgery. In the acute stage, the patient presented severe difficulties with comprehension, production and repetition, whereas she was able to correctly perform tasks that requested conceptual analysis and non-verbal operations. After recovering, the patient reported that she had been able to internally formulate her thoughts despite her overt phonological errors during the episode. Structural neuroimaging revealed that an extra-axial blood collection affected the middle frontal areas during the acute stage and that the white matter circuitry was left-lateralized before surgery. CONCLUSIONS: We deemed that the global aphasia episode was produced by a combination of the post-operative extra-axial blood collection directly impacting left middle frontal areas and a left-lateralization of the arcuate and/or uncinated fasciculi before surgery. Additionally, we advocate for a comprehensive evaluation of linguistic function that includes the assessment of IS and non-expressive language functions in similar cases.
