RESUMO

OBJECTIVE: Patient-reported outcome measures, while valuable, may not correlate with diagnostic test results. To better understand this potential discrepancy, our objective was to determine whether psychological health is an effect modifier of the association between patient-reported allergy outcome scores and allergy test results. STUDY DESIGN: Prospective outcomes study. SETTING: Tertiary care hospital and community-based clinic. METHODS: This study included 600 patients at least 18 years of age who presented for symptoms related to allergic rhinitis and completed the related sinonasal outcome test (SNOT), which includes validated nasal, allergy, and psychological domains. Stratified analyses of odds ratios and Spearman correlation coefficients were utilized to assess for effect modification by psychological status. RESULTS: Worse patient-reported allergic rhinitis symptoms were significantly associated with positive allergy test results (odds ratio [OR] 1.69, 95% confidence interval [CI] 1.22-2.34, P = .002) in patients with better psychological health. In contrast, there was no association in patients with worse psychological health (OR 1.06, 95% CI 0.36-3.10, P = .92). These findings were corroborated by assessments of correlation: allergy domain scores were positively correlated with allergy testing scores (Spearman rho 0.18, 95% CI 0.10-0.25, P < .001) in patients with better psychological health, while there was no correlation in patients with worse psychological health (-0.02, 95% CI -0.16-0.12, P = .77). CONCLUSIONS: Psychological status was an effect modifier of the association between allergy domain and allergy testing data. When assessing the relationship between subjective measures, such as sinonasal validated instruments, and objective measures, such as allergy test results, accounting for effect modifiers such as psychological state can provide clinical and research-related insights.

RESUMO

OBJECTIVE: To describe the development of a web-based data collection tool to track the management and outcomes of uveal melanoma patients. DESIGN: Description of a clinical registry. PARTICIPANTS: Patients with uveal melanoma. METHODS: A panel of expert ocular oncologists, with input from other relevant specialties and individuals with expertise in registry development, collaborated to formulate a minimum data set to be collected to track patient centred, real-world outcomes in uveal melanoma. This data set was used to create the Fight Tumour Blindness! (FTB!) registry within Save Sight Registries. RESULTS: The data set to be collected includes patient demographics and medical history, baseline visit, follow-up visit including tumour treatment, metastatic staging and surveillance, pathology, and patient-reported questionnaires. The inbuilt mechanisms to ensure efficient and complete data collection are described. CONCLUSIONS: The FTB! registry can be used to monitor outcomes for patients with uveal melanoma. It allows benchmarking of outcomes and comparisons between different clinics and countries.

RESUMO

AIM: To examine the level of adherence to best-practice guidelines of interprofessional teams with acute care nurse practitioners (ACNPs) compared to interprofessional teams without ACNPs. DESIGN: A retrospective observational study was conducted in 2023. METHOD: A retrospective cohort was created including 280 patients who underwent a coronary artery bypass graft and/or a valve repair and hospitalised in a cardiac surgery unit of a university affiliated hospital in Québec (Canada) between 1 January 2019 to 31 January 2020. The level of adherence to best-practice guidelines was measured from a composite score in percentage. The composite score was created from a newly developed tool including 99 items across six categories (patient information, pharmacotherapy, laboratory tests, post-operative assessment, patient and interprofessional teams' characteristics). Multivariate linear and logistic regression models were computed to examine the effect of interprofessional teams with ACNPs on the level of adherence to best-practice guidelines. RESULTS: Most of the patients of the cohort were male and underwent a coronary artery bypass graft procedure. Patients under the care of interprofessional teams with ACNP were 1.72 times more likely to reach a level of adherence higher than 80% compared to interprofessional teams without ACNPs and were 2.29 times more likely to be within the highest quartile of the scores for the level of adherence to best-practice guidelines of the cohort. IMPACT: This study provides empirical data supporting the benefits of ACNP practice for patients, interprofessional teams and healthcare organisations. RELEVANCE FOR PRACTICE: Our findings identify the important contributions of interprofessional teams that include ACNPs using a validated instrument, as well as their contribution to the delivery of high quality patient care. REPORTING METHOD: This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement: Guidelines for reporting observational studies guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMO

OBJECTIVES: To develop and assess the validity of a novel allergy-specific domain for the 22-item sino-nasal outcomes test (SNOT-22), to provide a new tool that efficiently quantifies the impact of allergic rhinitis (AR) concurrent with chronic rhinosinusitis. STUDY DESIGN: Prospective validation study. SETTING: Tertiary care hospital and community-based clinic. METHODS: Proposed items were developed based on clinician and patient input, and further assessed via factor analysis and for internal consistency (n = 1987). Items were then additionally assessed for convergent and discriminant validity (n = 415), applying data from concurrent completions of the Nasal Obstruction and Septoplasty Effectiveness Scale (NOSE), Mini-Rhinoconjunctivitis Quality-of-Life Questionnaire (MiniRQLQ), and validated global health assessments. Assessments of intra-rater reliability, responsiveness to change, and qualitative input were also performed. RESULTS: Factor analysis demonstrated that proposed allergy items mapped to a single domain. Items were internally consistent (Cronbach α: 0.80 within domain, 0.91 within all SNOT). In assessments of convergent validity, domain scores were associated with MiniRQLQ (Spearman's ρ: 0.46, 95% confidence interval [CI]: 0.30-0.59) and NOSE scores (0.36, 95% CI: 0.27-0.44). The novel items also discriminated among clinical states: a 1-point increase in domain score was associated with an 8.32 (95% CI: 5.43-12.75) increase in the odds of prompting a visit for allergy-related symptoms and a 1.52 (95% CI: 1.13-2.05) increase in the odds of positive allergy testing. Intra-rater reliability was substantial (Cohen's κ: 0.8, 95% CI: 0.8-0.9), and responsiveness to change was demonstrated (mean difference: -0.6, 95% CI: -0.8 to -0.4). CONCLUSIONS: This novel domain is a valid, efficient measure of AR alongside rhinosinusitis.

RESUMO

PURPOSE: To investigate clinical manifestations and prognoses in pediatric patients (≤12 years old) with ocular melanoma. METHODS: This was a retrospective, multicenter cohort study with individual participant data (IPD) meta-analysis pooling available published cases, and unpublished cases from an international collaboration of seven ocular oncology centers. RESULTS: There were 133 eyes of 133 pediatric patients with choroidal or ciliary body (n = 66 [50%]), iris (n = 33 [25%]), conjunctival (n = 26 [19%]), and eyelid (n = 8 [6%]) melanoma. Overall, the mean patient age at presentation was 7 years (median, 8; range, 1-12 years), with 63 males (49%). The mean age by tumor site was 6.50 ± 3.90, 7.44 ± 3.57, 9.12 ± 2.61, and 5.63 ± 2.38 years, for choroid/ciliary body, iris, conjunctiva, and eyelid melanoma, respectively (P = 0.001). Association with ocular melanocytosis was seen in 15%, 11%, 4%, and 0%, respectively (P = 0.01). Frequency of ocular melanoma family history did not vary by tumor site (7%, 17%, 9% and 12%, resp. [P = 0.26]). After mean follow-up of 74, 85, 50, and 105 months (P = 0.65), metastasis was seen in 12%, 9%, 19%, and 13% of choroid/ciliary body, iris, conjunctiva, and eyelid melanoma, respectively. Death was reported in 5%, 3%, 8%, and 0%, respectively, with survival analysis indicating higher mortality in choroidal/ciliary body and conjunctival melanoma patients. CONCLUSIONS: Ocular melanoma in the pediatric population is rare, with unique clinical features and outcomes. Iris melanoma accounts for about one-third of pediatric uveal melanoma cases.

RESUMO

Uveal melanoma (UM) is the principal type of intraocular malignancy in adults. Up to 50% of UM patients develop metastatic disease with very poor survival. There are few drugs available to treat the primary or metastatic UM. This study was undertaken to evaluate the anti-cancer effect of lapatinib and corroborate the potential of HER2 inhibition in the treatment of UM. The anti-UM activity of lapatinib was assessed using cell viability, cell death and cell cycle analysis, and its anti-metastatic actions were evaluated using would healing, invasion and colony formation assays. Immunoblotting was used to substantiate the actions of lapatinib on apoptotic and HER2 signaling. The anti-UM activity of lapatinib was further evaluated in a UM xenograft mouse model. Lapatinib decreased the viability of four UM cell lines (IC50: 3.67-6.53 µM). The antiproliferative activity of lapatinib was corroborated in three primary cell lines isolated from UM patient tumors. In UM cell lines, lapatinib promoted apoptosis and cell cycle arrest, and strongly inhibited cell migration, invasion and reproductive cell growth. Lapatinib dysregulated HER2-AKT/ERK/PI3K signalling leading to the altered expression of apoptotic factors and cell cycle mediators in UM cell lines. Importantly, lapatinib suppressed tumourigenesis in mice carrying UM cell xenografts. Together the present findings are consistent with the assertion that HER2 is a viable therapeutic target in UM. Lapatinib is active in primary and metastatic UM as a clinically approved HER2 inhibitor. The activity of lapatinib in UM patients could be evaluated in future clinical trials.

RESUMO

BACKGROUND: The combination of pembrolizumab, an anti-PD-1 antibody, and lenvatinib, an antiangiogenic multikinase inhibitor, shows synergistic activity in preclinical and clinical studies in solid tumours. We assessed the clinical activity of this combination therapy in patients with pleural mesothelioma who progressed after platinum-pemetrexed chemotherapy. METHODS: In this single-arm, single-centre, phase 2 study, done at the Netherlands Cancer Institute in Amsterdam, The Netherlands, eligible patients (aged ≥18 years) with pleural mesothelioma with an Eastern Cooperative Oncology Group performance status of 0-1, progression after chemotherapy (no previous immunotherapy), and measurable disease according to the modified Response Evaluation Criteria In Solid Tumours (mRECIST) for mesothelioma version 1.1. Patients received 200 mg intravenous pembrolizumab once every 3 weeks plus 20 mg oral lenvatinib once per day for up to 2 years or until disease progression, development of unacceptable toxicity, or withdrawal of consent. The primary endpoint was objective response rate identified by a local investigator according to mRECIST version 1.1. This trial is registered with ClinicalTrials.gov, NCT04287829, and is recruiting for the second cohort. FINDINGS: Between March 5, 2021, and Jan 31, 2022, 42 patients were screened, of whom 38 were included in the primary endpoint and safety analyses (median age 71 years [IQR 65-75], 33 [87%] male and five [13%] female) . At data cutoff (Jan 31, 2023), with a median follow-up of 17·7 months (IQR 13·8-19·4), 22 (58%; 95% CI 41-74) of 38 patients had an objective response. The independent review showed an objective response in 17 (45%; 95% CI 29-62) of 38 patients. Serious treatment-related adverse events occurred in ten (26%) patients, including one treatment-related death due to myocardial infarction. The most common treatment-related grade 3 or worse adverse events were hypertension (eight patients [21%]) and anorexia and lymphopenia (both four patients [11%]). In 29 (76%) of 38 patients, at least one dose reduction or discontinuation of lenvatinib was required. INTERPRETATION: Pembrolizumab plus lenvatinib showed promising anti-tumour activity in patients with pleural mesothelioma with considerable toxicity, similar to that in previous studies. Available evidence from the literature suggests a high starting dose of lenvatinib for optimal anti-tumour activity. This, however, demands a high standard of supportive care. The combination therapy of pembrolizumab and lenvatinib warrants further investigation in pleural mesothelioma. FUNDING: Merck Sharp & Dohme.

RESUMO

Many patients (20%-30%) experience suboptimal weight loss (WL) after bariatric surgery (BS), and unrealistic preoperative WL expectations may be a contributing factor. This study aimed to describe the nature of patients' general expectations of BS during the pre-surgical period, and how patients determined whether their expectations and WL goals (WLGs) were realistic. The extent to which patients' expectations and WLGs were met and/or changed during the post-surgical period was also assessed. Semi-structured interviews were conducted with 15 preoperative patients recruited approximately 6-months before surgery. Focus groups were also conducted with 14 post-operative patients recruited approximately 6-months after surgery. Interviews and focus groups were audio-recorded, transcribed verbatim and analysed using qualitative content analysis. Preoperative patients reported expectations that BS would positively impact physical and psychological health, social relationships, as well as quality of care. Preoperative patients perceived that they and their health care professionals had unrealistically high expectations of WL. Post-operative patients reported being generally satisfied with the outcomes of surgery, even though many did not reach their expected WL. Finally, most post-operative patients reported changing their expectations from pre- to post-surgery. This study provides data that may help inform the development of preoperative interventions focusing on helping patients set realistic expectations for WL and related outcomes, which could better prepare patients for the challenges they will face after surgery.

RESUMO

BACKGROUND: Acute care nurse practitioners (ACNPs) in postoperative cardiac surgery settings provide significant benefits to patients and organizations. Recent studies have suggested that ACNPs increase the level of adherence to best-practice guidelines by interprofessional teams. It is however, unknown whether interprofessional teams with ACNP are associated with higher levels of adherence to best-practice guidelines compared to interprofessional teams without ACNPs. Furthermore, no extraction tool is available to measure the level of adherence to best-practice guidelines by interprofessional teams in postoperative cardiac surgery settings. This project aims to measure and examine the level of adherence to best-practice guidelines of interprofessional teams with and without ACNPs in a postoperative cardiac surgery setting in Québec, Canada. METHODS: A retrospective observational study will be conducted of 300 patients hospitalized between January 1, 2019 and January 31, 2020 in a postoperative cardiac surgery unit in Québec, Canada. Data will be collected from patient health records and electronic databases. An extraction tool will be developed based on systematic review of the literature, and will include best-practice guidelines and confounding variables related to patient and interprofessional teams' characteristics. Content and criterion validation, and a pilot-test will be conducted for the development of the tool. A multivariate linear regression model will be developed and adjusted for confounding variables to examine the association between interprofessional teams with and without ACNPs, and level of adherence to best-practice guidelines by those teams. DISCUSSION: This project represents the first study to measure and examine the level of adherence to best-practice guidelines by interprofessional teams with and without ACNPs in a postoperative cardiac surgery setting. The findings of this project will generate empirical data focusing on the contribution of ACNPs within interprofessional teams, and ultimately enhance the delivery of high quality and evidence-based care for patients and families.

RESUMO

INTRODUCTION: The protein Klotho (KL) was first discovered in KL-deficient mice, which developed a syndrome similar to premature aging in humans. Since then, KL has been implicated in multiple molecular signaling pathways and diseases. KL has been shown to have anti-aging, healthspan and lifespan extending, cognitive enhancing, anti-oxidative, anti-inflammatory, and anti-tumor properties. KL levels decrease with age and in many diseases. Therefore, it has been of great interest to develop a KL-boosting or restoring drug, or to supplement endogenous Klotho with exogenous Klotho genetic material or recombinant Klotho protein, and to use KL levels in the body as a marker for the efficacy of such drugs and as a biomarker for the diagnosis and management of diseases. OBJECTIVE: The goal of this study was to provide a comprehensive review of KL levels across age groups in individuals who are healthy or have certain health conditions, using four sources: blood, cerebrospinal fluid, urine, and whole biopsy/necropsy tissue. By doing so, baseline KL levels can be identified across the lifespan, in the absence or presence of disease. In turn, these findings can be used to guide the development of future KL-based therapeutics and biomarkers, which will heavily rely on an individual's baseline KL range to be efficacious. METHODS: A total of 65 studies were collected primarily using the PubMed database. Research articles that were published up to April 2022 were included. Statistical analysis was conducted using RStudio. RESULTS: Mean and median blood KL levels in healthy individuals, mean blood KL levels in individuals with renal conditions, and mean blood KL levels in individuals with metabolic or endocrine conditions were shown to decrease with age. Similarly, CSF KL levels in patients with AD also declined compared with age-matched controls. CONCLUSIONS: The present study confirms the trend that KL levels in blood decrease with age in humans, among those who are healthy, and even further among those with renal and endocrine/metabolic illnesses. Further, by drawing this trend from multiple published works, we were able to provide a general idea of baseline KL ranges, specifically in blood in these populations. These data add to the current knowledge on normal KL levels in the body and how they change with time and in disease, and can potentially support efforts to create KL-based treatments and screening tools to better manage aging, renal, and metabolic/endocrine diseases.

RESUMO

OBJECTIVES: Uveal melanoma (UM) is the most common primary intraocular tumour in adults. UM has a poor overall prognosis and ~50% of patients progress to metastatic disease that has a median survival of 5.2 months. There are currently no proven pharmacological treatments for primary or metastatic UM. Research efforts continue to seek new agents. Many natural compounds have shown promising anti-UM activity in in-vitro and/or in-vivo studies. This review summarises the current findings for natural compounds that may be potentially useful in treating UM. KEY FINDINGS: Literature suggests that natural compounds, such as pristimerin, picropodophyllin, oridonin, zeaxanthin, withaferin and FR-900359, may be promising candidate compounds to treat UM. Most of these compounds have demonstrated satisfactory efficacy in inhibiting in-vitro UM cell growth. SUMMARY: The evidence regarding the anti-UM effects of natural compounds is mainly limited to in-vitro studies; to date, only a small number of these agents have been evaluated in vivo. The molecular mechanisms underpinning the anti-UM properties of these compounds remain largely undefined. Further studies are required to evaluate the in-vivo anticancer activity, appropriate dosage regimen and safety of natural compounds that could be developed for use in UM.

RESUMO

Purpose: Familial adenomatous polyposis (FAP) has an almost 100% colorectal cancer risk warranting early detection in gene carriers. This study presents congenital hypertrophy of the retinal pigment epithelium (CHRPE) as a highly specific phenotypical marker for FAP that can be used in screening at-risk individuals. Screening recommendations including morphological subclassification were formulated with supporting literature. Methods: A systematic literature review with a comprehensive search strategy was conducted using online databases. Manual searches of bibliographies and reference lists were also performed. Studies meeting inclusion criteria were graded with respect to their hierarchy of evidence and strength of recommendations according to the National Health and Medical Research Council (NHMRC) guidelines of Australia. Results: Almost 4500 participants were analysed across 28 included studies. The mean specificity of CHRPE as a phenotypical screening marker of FAP was 89% (standard deviation (SD); 14) with a mean sensitivity of 79% (SD; 8). The mean prevalence of CHRPE amongst FAP participants; at-risk participants were found to be 76% (SD; 24) and 37% (SD; 21) respectively. Bilateralism and multiple lesion number ≥3 are features highly specific for FAP. Conclusion: CHRPE was found to be a non-invasive, rapid, early phenotypical screening marker of FAP. Clinical recognition further allows increased gene analysis efficiency. The absence of CHRPE alone cannot exclude FAP. Our screening recommendations provide guidance to clinicians on evidence based CHRPE assessment. We would advocate inclusion of ocular examinations as part of a three-pronged approach, along with endoscopy and genetic testing, for efficient, timely FAP assessment in at-risk individuals.

RESUMO

PURPOSE: BAP1 germline mutation can promote risk of uveal melanoma and mesothelioma. In this study, we report a patient with BAP1 germline mutation and uveal melanoma who developed a rare form of mesothelioma in the peritoneum. METHOD: Case report. RESULTS: A 55-year-old white man noted blurred vision in the left eye. Examination revealed superotemporal episcleral sentinel vessels and a dark brown iris mass suspicious for melanoma, with angle invasion and involvement of the ciliochoroidal region. The tumor measured 14 mm in diameter and 10.3 mm in thickness. A diagnosis of iridociliochoroidal melanoma was rendered and plaque radiotherapy applied. Genetic testing revealed BAP1 germline mutation. At 3.5-year follow-up, tumor control was achieved, but radiation-related complications led to enucleation. At 5.5-year follow-up, incidental findings by laparoscopy revealed multiple peritoneal tumors, histopathologically proven to be malignant peritoneal mesothelioma. Lung evaluation was normal, and there was no melanoma-related or mesothelioma-related metastasis. Likewise, magnetic resonance imaging of the abdomen showed no evidence of hepatic metastasis. CONCLUSION: BAP1 tumor predisposition syndrome can promote risk of uveal melanoma and malignant peritoneal mesothelioma. Cancer screening for these malignancies is warranted.

RESUMO

BACKGROUND: Prognostic cytological and molecular features of uveal melanoma have been well researched and are essential in management. Samples can be obtained in vivo through fine needle aspirate biopsy, vitrector cutter, forceps or post-enucleation for off-site testing. This study aims to examine cytological and chromosome microarray yields of these samples. METHODS: A retrospective cohort analysis of 119 uveal melanoma biopsies submitted to our laboratory. Samples included those taken in vivo (n = 57) and post-enucleation (n = 62). Patient and tumour features were collected including age, sex, primary tumour location, basal diameter and tumour height. Prognostic outcomes measured include cell morphology, chromosomal status and immunohistochemistry. RESULTS: Post-enucleation biopsies accounted for just over half of our samples (52%). Post-enucleation samples had a more successful genetic yield than in vivo biopsies (77% vs. 50%, p = 0.04) though there was no difference for cytological yields. There was no difference in cytological or microarray yields between instruments. The vitrector biopsy group had the smallest tumour thickness (5 mm vs. 10 mm [fine-needle aspirate biopsy], p = 0.003). There was a strong correlation between monosomy 3, BAP1 aberrancy and epithelioid cell type in post-enucleation samples (Tb  = 0.742, p = 0.005). However, epithelioid morphology was not associated with either monosomy 3 (p = 0.07) or BAP1 aberrancy (p = 0.24) for in vivo biopsies. CONCLUSIONS: All three biopsy instruments provide similar cytological yields as post-enucleation sampling, although post-enucleation samples had a more successful chromosome microarray yield. Epithelioid cytomorphology alone is insufficient for prognostication in in vivo biopsies, immunohistochemistry would be a useful surrogate test.

RESUMO

BACKGROUND: Empirical findings have shown significant and non-significant effects of advanced practice nursing roles within postoperative cardiac settings. The inconsistencies of the current literature preclude the identification of a significant effect of advanced practice nursing roles on patient and organizational outcomes. OBJECTIVE: 1) identify patient and organizational outcomes of advanced practice nursing roles in postoperative cardiac surgery and 2) synthesize the evidence of current roles of advanced practice nurses in postoperative cardiac surgery to provide the best quality of care for patients. METHOD: A systematic review of randomized controlled trials was conducted in six electronic databases, including Medline, CINHAL, Embase, Cochrane Database, Joanna Briggs Database and Web of Science, and the grey literature. Randomized controlled trials published after 1999 were included if they examined advanced practice nursing roles and recruited patients who underwent cardiac surgery. The study selection was performed by two independent reviewers, and consensus was achieved with a third reviewer. Data extraction was conducted by one reviewer and revised by a second reviewer. The methodological quality of the included studies was assessed with the Evidence Project risk of bias tool by two independent reviewers and revised by a third reviewer. A narrative synthesis of the available evidence was completed. No meta-analysis technique was attempted because of the high heterogeneity of the included studies. RESULTS: Among 4,448 retrieved papers, ten randomized controlled trials and three secondary analyses were included in this review. The methodological quality of the included studies was moderate. All studies included a comparison group and the majority of the studies collected data using a blinded researcher. However, all studies were based on small sample sizes and failed to randomly recruit participants. Five studies implemented nurse practitioner roles and five studies implemented clinical nurse specialist roles. The advanced practice nursing care included health condition management, lifestyle promotion and coping strategies with patients. A total of 22 outcomes were identified, including 13 patient outcomes (e.g., depressive symptoms) and nine organizational outcomes (e.g., rehospitalization after discharge). Each outcome was examined in one to five studies. All of the included outcomes were associated with inconsistent findings. CONCLUSION: The findings from existing literature remain inconsistent. The high risk of bias and the small sample sizes could potentially explain the non-significant findings. Avenues for future research should focus on the development of methodologically high-quality studies with larger sample sizes to enhance our understanding of the effectiveness of advanced practice nursing roles.

RESUMO

The elastic-plastic properties of mesoscale electrodeposited LIGA Ni alloy specimens are investigated as a function of specimen size, strain rate, and material composition. Two material compositions are studied: a high-strength fine-grained Ni-Fe alloy and a high-ductility coarse-grained Ni-Co alloy. The specimens have thicknesses of approximately 200 µm and gauge widths ranging from 75 µm to 700 µm. Tensile tests are conducted at strain rates of 0.001/s and 1/s using tabletop loading apparatuses and digital image correlation (DIC) for strain measurement. For each test condition, the apparent Young's modulus, yield strength, ultimate tensile strength, and strain hardening exponent and strength coefficient are extracted from the tensile tests. The true strains to failure are also assessed from fractography. Size, rate, and composition effects are discussed. For most properties, the statistical scatter represented by the standard deviation exceeds the measurement uncertainty; the notable exceptions to these observations are the apparent Young's modulus and yield strength, where large measurement uncertainties are ascribed to common experimental factors and material microplasticity.

RESUMO

Metabolic and bariatric surgery (MBS) yields unprecedented clinical outcomes, though variability is high in weight change and health benefits. Behavioral weight management (BWM) interventions may optimize MBS outcomes. However, there is a lack of an evidence base to inform their use in practice, particularly regarding optimal delivery timing. This paper evaluated the efficacy of BWM conducted pre- versus post- versus pre- and post-MBS. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and included pre- and/or post-operative BWM interventions in adults reporting anthropometric and/or body composition data. Thirty-six studies (2,919 participants) were included. Post-operative BWM yielded greater decreases in weight (standardized mean difference [SMD] = -0.41; 95% confidence interval [CI]: -0.766 to -0.049, p < 0.05; I2 = 93.5%) and body mass index (SMD = -0.60; 95% CI: -0.913 to -0.289, p < 0.001; I2 = 87.8%) relative to comparators. There was no effect of BWM delivered pre- or joint pre- and post-operatively. The risk of selection and performance bias was generally high. Delivering BWM after MBS appears to confer the most benefits on weight, though there was high variability in study characteristics and risk of bias across trials. This provides insight into the type of support that should be considered post-operatively.

RESUMO

PURPOSE: To determine the association between vitreoretinal lymphoma and systemic lymphoma (SL). METHODS: Single-center retrospective review of medical records. RESULTS: Of 95 patients with vitreoretinal lymphoma, 18 (19%) had associated SL (SL group) and 77 (81%) were not associated with SL (no SL group). The most common sites of SL were skin (n = 5), testis (n = 2), liver and breast (n = 2), and others (n = 9). A comparison (SL group vs. [vs.] no SL group) revealed no difference in demographic or ocular findings at initial visit. In the SL group, SL occurred before the onset of ocular symptoms in 14 (78%) patients with mean interval of 86 months (median 61, range 5-286 months) or after ocular symptoms in 4 (22%) patients with mean interval of 19 months (median 12, range 7-44 months). A comparison revealed no difference in overall frequency of pre-existing or eventual central nervous SL (50% vs. 53%, P = 0.99); however, the SL group demonstrated central nervous SL more often after onset of ocular symptoms (78% vs. 17%, P = 0.001). A comparison found no difference in treatment methods, response of vitreoretinal lymphoma to treatment, final visual outcome, or death rate. CONCLUSION: We found 19% of patients with vitreoretinal lymphoma demonstrate related SL, and there was no difference in demographics, clinical features, or response to treatment, compared to those not associated with SL.

RESUMO

BACKGROUND/PURPOSE: To report the largest case series to date of uveitis occurring in association with immunomodulatory therapy for malignant melanoma. METHODS: A retrospective multicenter case review. Twenty-two patients with uveitis occurring in association with either immunotherapy or targeted immune therapy for malignant melanoma were identified. RESULTS: Of 22 patients, 11 had anterior uveitis in isolation. The remainder showed a variety of clinical features including panuveitis, ocular hypotony, papillitis, cystoid macular edema, and melanoma-associated retinopathy. Most patients responded well to treatment. CONCLUSION: We report the largest case series to date of patients with uveitis secondary to drug treatment for malignant melanoma. These cases are likely to increase in number in the future as newer immunomodulatory therapies for cancers are developed and the indications for these drugs increase. A dilemma arises when patients respond well to these drugs but develop vision-threatening side effects.

RESUMO

PURPOSE: To describe the outcome of ultra-low-dose (boom-boom) radiotherapy for choroidal lymphoma. METHODS: Retrospective series of three consecutive patients with biopsy-proven choroidal lymphoma treated with ultra-low-dose radiotherapy. RESULTS: The three patients (two male, one female) of mean age 70 years (range, 64-74 years) demonstrated presenting visual acuity in the affected eye between 20/40 and 20/50. The choroidal lymphoma was unilateral in all cases and presented with multifocal yellow patchy choroidal infiltration, located in all four quadrants and measuring mean 2.9 mm (range, 1.9-4.0 mm) in thickness by ultrasonography. Anterior epibulbar extension of 5 mm diameter was noted in one case. By enhanced depth imaging optical coherence tomography, the choroidal infiltration demonstrated classic undulating appearance (n = 3), with subretinal fluid (n = 2) and intraretinal edema (n = 1). There was no systemic lymphoma in any case. Biopsy was performed in all three cases and was diagnostic (n = 1) or suggestive (n = 2) of B-cell lymphoma. Management involved ultra-low-dose radiotherapy (4 Gy delivered in two fractions, "boom-boom"). On follow-up (mean = 14 months, range = 6-24 months), complete tumor regression on ophthalmoscopy was documented in all three cases, with enhanced depth imaging optical coherence tomography and ultrasonography demonstrating evidence of lymphoma resolution and visual acuity improvement to 20/25-20/40. There were no radiation complications. CONCLUSION: In this small case series, ultra-low-dose (boom-boom) radiotherapy was effective for choroidal lymphoma with favorable response and minimal side effects.
