RESUMO

Improving equity in women's health requires gender-specific and empowering approaches. However, health programs often disempower women by adopting a 'one-size-fits-all' approach that emphasizes diet, exercise and weight loss over other important aspects like sleep and mental wellbeing. This article reports on the design of Next Level Health (NLH), a program that aims to empower women through developing a wide range of health behaviors to support their holistic wellbeing. NLH is grounded by ethics, theory and evidence to support women to make achievable, sustainable changes that are relevant to their everyday lives. Women utilized the NLH framework to develop an integrative health routine across six domains: physical activity, sleep, nutrition, eating behavior, self-care and stress management. The framework guided them to set small, incremental goals that were adaptive to their needs and built from their existing circumstances. Participants reflected on their progress with a facilitator during monthly meetings, accessed a social media support page and received monthly text messages. Health programs remain an essential approach to improving women's health alongside community- and policy-level strategies. The development of NLH exemplifies how evidence may partner with modern health promotion values to inform relevant and ethical program design for women.


In western societies, health programs often focus on weight loss through exercise and diet to promote women's health. Such approaches disempower women by undervaluing important factors affecting their health like stress and sleep and narrow their scope for 'health success'. This article reports on the development of Next Level Health (NLH) that aims to help women gain greater health-related control by broadening their approach to health. The program is designed to support women to set small, achievable goals across six domains (physical activity, sleep, nutrition, eating behavior, self-care, and stress management) toward developing positive and sustainable health behaviors. Although women work with a facilitator each month to set goals, they are ultimately in control of formulating their health plans and their progression through NLH. Women can support each other by joining a community of other NLH participants through a social media group. NLH offers a novel program that is responsive to women's individual health needs and broadens their potential for health success.

RESUMO

BACKGROUND: Firefighters have occupational and environmental exposures to per- and polyfluoroalkyl substances (PFAS). The goal of this study was to compare serum PFAS concentrations across multiple United States fire departments to National Health and Nutrition Examination Survey (NHANES) participants. METHODS: Nine serum PFAS were compared in 290 firefighters from four municipal fire departments (coded A-D) and three NHANES participants matched to each firefighter on sex, ethnicity, age, and PFAS collection year. Only Departments A and C had sufficient women study participants (25 and six, respectively) to compare with NHANES. RESULTS: In male firefighters compared with NHANES, geometric mean perfluorohexane sulfonate (PFHxS) was elevated in Departments A-C, sum of branched perfluoromethylheptane sulfonate isomers (Sm-PFOS) was elevated in all four departments, linear perfluorooctane sulfonate (n-PFOS) was elevated in Departments B and C, linear perfluorooctanoate (n-PFOA) was elevated in Departments B-D, and perfluorononanoate (PFNA) was elevated in Departments B-D, but lower in A. In male firefighters compared with NHANES, perfluoroundecanoate (PFUnDA) was more frequently detected in Departments B and D, and 2-(N-methyl-perfluorooctane sulfonamido) acetate (MeFOSAA) was less frequently detected in Departments B-D. In female firefighters compared with NHANES, PFHxS and Sm-PFOS concentrations were elevated in Departments A and C. Other PFAS concentrations were elevated and/or reduced in only one department or not significantly different from NHANES in any department. CONCLUSIONS: Serum PFHxS, Sm-PFOS, n-PFOS, n-PFOA, and PFNA concentrations were increased in at least two of four fire departments in comparison to NHANES.

RESUMO

Purpose: Head and neck (HN) radiotherapy (RT) is complex, involving multiple target and organ at risk (OAR) structures delineated by the radiation oncologist. Site-agnostic peer review after RT plan completion is often inadequate for thorough review of these structures. In-depth review of RT contours is critical to maintain high-quality RT and optimal patient outcomes. Materials and Methods: In August 2020, the HN RT Quality Assurance Conference, a weekly teleconference that included at least one radiation oncology HN specialist, was activated at our institution. Targets and OARs were reviewed in detail prior to RT plan creation. A parallel implementation study recorded patient factors and outcomes of these reviews. A major change was any modification to the high-dose planning target volume (PTV) or the prescription dose/fractionation; a minor change was modification to the intermediate-dose PTV, low-dose PTV, or any OAR. We analysed the results of consecutive RT contour review in the first 20 months since its initiation. Results: A total of 208 patients treated by 8 providers were reviewed: 86·5% from the primary tertiary care hospital and 13·5% from regional practices. A major change was recommended in 14·4% and implemented in 25 of 30 cases (83·3%). A minor change was recommended in 17·3% and implemented in 32 of 36 cases (88·9%). A survey of participants found that all (n = 11) strongly agreed or agreed that the conference was useful. Conclusion: Dedicated review of RT targets/OARs with a HN subspecialist is associated with substantial rates of suggested and implemented modifications to the contours.

RESUMO

PURPOSE: To correlate changes in urinary patient-reported outcomes including the International Prostate Symptom Score (IPSS), acute urinary retention and urethral stricture with urethral dose in those treated with low dose rate (LDR) prostate brachytherapy. MATERIALS AND METHODS: Patients treated with prostate LDR between 2012 and 2019 (n=117) completed IPSS urinary symptom assessments prior to treatment and at each follow-up. CT simulation was obtained with urinary catheter 1-month post-implant for dosimetric analysis. 113 patients with pre- and ≥1 post-LDR IPSS score available were analyzed. Urethral dosimetric parameters including U75, U100, U125, U150 and U200 were abstracted from post-implant dosimetry and assessed for association with urinary toxicity using bivariate logistic regression and Spearman correlation. Outcomes included clinically significant change (CSC, defined as 4 or more points or 25% rise above baseline) in IPSS score at 6 and 12 months, acute urinary retention (AUR), and urethral stricture (US). RESULTS: 89 (79%) patients were treated with LDR monotherapy (145 Gy) and 24 (21%) with LDR boost (110 Gy) with external beam radiation therapy. Twenty (18%) had baseline IPSS ≥15. Median IPSS scores were: baseline 6 (3-12; n=113), 1-month 17 (10-25; n=110), 6 months 12 (7-18; n=77), 1 year 8 (5-14; n=52). CSC-6 was observed in 59 (77%), CSC-12 in 26 (50%), AUR in 12 (11%), and US in 4 (4%). No association was identified between urethral dose parameters and CSC-6, CSC-12, AUR, or US. No correlation between urethral dose and IPSS at 6- and 12-months was identified. The IPSS ≥15 group exhibited lower rates of CSC-12 (13% v. 57%, p=0.05) but not CSC-6 (55% v. 80%, p=0.12). CONCLUSIONS: We did not find a relationship between urethral dose and IPSS elevation, AUR or US. We did identify a significantly lower change in IPSS at 12 months for those with baseline IPSS ≥15 compared to those with low baseline scores.

RESUMO

PURPOSE: Fiscal distress or "financial toxicity," in which patients experience challenges in paying for treatment, are becoming dominant problems for patients with cancer because of burgeoning health care costs and strategies implemented by health insurance payers to reduce their level of expenditure. We report the structure and function of the first Financial Toxicity Tumor Board (FTTB). Modeled on the concept of a conventional multidisciplinary tumor board, FTTB functions as a multidisciplinary conference providing broad problem-solving approaches to financial toxicity. METHODS: The FTTB, with participation from physicians, nurses, financial counselors, nurse navigators, social workers, and administrators, meets monthly and is focused on financial toxicity and financial worry experienced by patients with cancer. It is linked to a Patient Assistance Program for oncologic pharmaceutical agents as this domain constitutes a critical area of financial toxicity for many patients. RESULTS: In the first years of function, more than $55-$60 million of personal expenditure has been avoided for 1,749 and 1,819 patients, respectively, as well as more than $1.3 million copay assistance provided for financially challenged patients. Problems addressed have included payer impediments, underinsurance, complexities of certification, coding or billing issues, and inadequate internal standard operating procedures. CONCLUSION: A focus on proactive management of financial toxicity through the function of multidisciplinary FTTBs substantially ameliorates this burgeoning international problem. This concept is presented early as it may be leveraged readily in other centers.

RESUMO

BACKGROUND AND PURPOSE: Among patients undergoing serial neck CTs, we have observed variability in the appearance of the pharyngolaryngeal venous plexus, which comprises the postcricoid and posterior pharyngeal venous plexuses. We hypothesize changes in plexus appearance from therapeutic neck irradiation. The purposes of this study are to describe the CT appearance of the pharyngolaryngeal venous plexus among 2 groups undergoing serial neck CTs-patients with radiation therapy-treated laryngeal cancer and patients with medically treated lymphoma-and to assess for changes in plexus appearance attributable to radiation therapy. MATERIALS AND METHODS: For this retrospective study of 98 patients (49 in each group), 448 contrast-enhanced neck CTs (222 laryngeal cancer; 226 lymphoma) were assessed. When visible, the plexus anteroposterior diameter was measured, and morphology was categorized. RESULTS: At least 1 plexus component was identified in 36/49 patients with laryngeal cancer and 37/49 patients with lymphoma. There were no statistically significant differences in plexus visibility between the 2 groups. Median anteroposterior diameter was 2.1 mm for the postcricoid venous plexus and 1.6 mm for the posterior pharyngeal venous plexus. The most common morphology was "bilobed" for the postcricoid venous plexus and "linear" for the posterior pharyngeal venous plexus. The pharyngolaryngeal venous plexus and its components were commonly identifiable only on follow-up imaging. CONCLUSIONS: Head and neck radiologists should be familiar with the typical location and variable appearance of the pharyngolaryngeal plexus components so as not to mistake them for neoplasm. Observed variability in plexus appearance is not attributable to radiation therapy.

RESUMO

BACKGROUND: Previous studies have suggested improved efficiency and patient outcomes with 125I seed compared with hookwire localization (HWL) in breast-conserving surgery, but high-level evidence of superior surgical outcomes is lacking. The aim of this multicentre pragmatic RCT was to compare re-excision and positive margin rates after localization using 125I seed or hookwire in women with non-palpable breast cancer. METHODS: Between September 2013 and March 2018, women with non-palpable breast cancer eligible for breast-conserving surgery were assigned randomly to preoperative localization using 125I seeds or hookwires. Randomization was stratified by lesion type (pure ductal carcinoma in situ (DCIS) or other) and study site. Primary endpoints were rates of re-excision and margin positivity. Secondary endpoints were resection volumes and weights. RESULTS: A total of 690 women were randomized at eight sites; 659 women remained after withdrawal (125I seed, 327; HWL, 332). Mean age was 60.3 years in the 125I seed group and 60.7 years in the HWL group, with no difference between the groups in preoperative lesion size (mean 13.2 mm). Lesions were pure DCIS in 25.9 per cent. The most common radiological lesion types were masses (46.9 per cent) and calcifications (28.2 per cent). The localization modality was ultrasonography in 65.5 per cent and mammography in 33.7 per cent. The re-excision rate after 125I seed localization was significantly lower than for HWL (13.9 versus 18.9 per cent respectively; P = 0.019). There were no significant differences in positive margin rates, or in specimen weights and volumes. CONCLUSION: Re-excision rates after breast-conserving surgery were significantly lower after 125I seed localization compared with HWL.

RESUMO

PURPOSE: This multicenter service evaluation explores the efficacy and tolerability of brivaracetam (BRV) in an unselected, consecutive population in 'real-life' clinical settings. METHOD: We retrospectively collected data from patient records at 11 UK hospitals and epilepsy centers. Consecutive patients prescribed BRV with at least 3 months of follow-up (FU) were included. Apart from reporting effectiveness and tolerability of BRV across the whole cohort, we compared treatment outcomes depending on previous levetiracetam use (LEV+ versus LEV-), comorbid learning disability (LD+ versus LD-), and epilepsy syndrome (focal versus generalized epilepsy). RESULTS: Two hundred and ninety patients (46% male, median age: 38 years, range: 15 to 77) with ≥3 months of FU were included. The median duration of BRV exposure was 12 months (range: 1 day to 72 months). Overall BRV retention was 71.1%. While 56.1% of patients improved in terms of seizure frequency category (daily, weekly, monthly, yearly seizures), 23.1% did not improve on this measure and 20.8% deteriorated. In terms of seizure frequency, 21% of patients experienced a ≥50% reduction, with 7.0% of all patients becoming seizure-free. Treatment-emergent adverse events (AEs) were reported by 107 (36.9%) patients, but there were no serious AEs. The commonest AEs were sedation/fatigue (18.3%), mood changes (9.0%), and irritability/aggression (4.8%). There were no significant differences in drug retention, seizure frequency outcomes, or AEs between the LEV+ and LEV- subgroups, or between patients with generalized or focal epilepsies. Although 15.5% of patients in the LD+ group achieved a ≥50% reduction, this rate was lower than in the LD- group. CONCLUSIONS: This 'real-life' evaluation suggests that reductions in seizure frequency can be achieved with BRV in patients with highly refractory epilepsy. Brivaracetam may be a useful treatment option in patients who have previously failed to respond to or tolerate LEV, those with LD, or (off-label) those with generalized epilepsies.

RESUMO

AIMS: To evaluate focal high dose rate (HDR) brachytherapy in locally recurrent prostate cancer. MATERIALS AND METHODS: Patients with biochemical relapse after non-surgical primary treatment for localised prostate cancer were selected after a negative screen for metastatic disease. Template mapping biopsies combined with multiparametric magnetic resonance imaging were used to identify the location of the tumour and the focal clinical target volume. The planning aim dose prescription was 19 Gy. Outcome measures were biochemical relapse-free survival and toxicity using International Prostate Symptom Score and Common Terminology Criteria for Adverse Events (version 4.0) scores. RESULTS: Between March 2013 and December 2018, 50 patients underwent salvage HDR brachytherapy. The median follow-up was 21 months (range 1-53). Biochemical progression-free survival at 2 and 3 years was 63% and 46%, respectively. On multivariate analysis, only prostate-specific antigen nadir ≤0.5 ng/ml post-salvage (P = 0.03, hazard ratio 0.04) was associated with biochemical progression-free survival. Relapse was associated with distant metastases in 11/13 patients in whom this was investigated. Late grade 3 genitourinary toxicities were gross haematuria (three patients), severe lower urinary tract symptoms (two patients), erectile dysfunction (one patient) and urethral stricture requiring surgery (four patients). No acute and late grade 4 or 5 genitourinary and no grade 3 or higher gastrointestinal toxicities were recorded. CONCLUSIONS: Focal salvage HDR monotherapy achieves biochemical control in 46% of patients at 3 years with acceptable toxicity rates in selected patients. Biochemical relapse was related to a post-salvage prostate-specific antigen nadir of ≥0.5 ng/ml. Long-term outcomes are needed to assess the impact on the natural history of prostate cancer in these patients.

RESUMO

SETTING A free, national smoking cessation service for adults based on behavioural and pharmaceutical support in Wales, UK. OBJECTIVE To establish whether the Fagerström score at the assessment session could be used to predict subsequent treatment attendance. Non-attendance affects the individual's health and the efficiency of the service. DESIGN Anonymised data from 39 967 Stop Smoking Wales assessment session attendees were assessed using logistic regression. The outcome variable was subsequent attendance/non-attendance for at least one treatment session. Fagerström scores were grouped into 'very low' (0-2), 'low' (3-4), 'medium' (5) and 'high' (6-10). RESULTS People with medium (OR 1.15, 95%CI 1.08-1.24) or low Fagerström scores (OR 1.07, 95%CI 1.00-1.14) were more likely to attend treatment sessions than people with very low (OR 1.03, 95%CI 0.94-1.12) or high (baseline) Fagerström scores. The final model comprised nine other statistically significant covariates: current age, sex, residential deprivation level, number of previous quit attempts, type of appointment (group or one-to-one), time of appointment, appointment season, time spent waiting for an appointment and distance from home to the clinic. CONCLUSION The Fagerström score at the assessment session could be used to identify smokers at an increased risk of not attending subsequent treatment. Further research is required to evaluate the impact of targeting those with the highest and lowest Fagerström scores at the assessment session upon treatment attendance. .

RESUMO

Terrestrial plants have contributed massively to the development of modern oncologic drugs. Despite the wide acceptance of Mauritian endemic flowering plants in traditional medicine, scientific evidence of their chemotherapeutic potential is lacking. This study aimed to evaluate the in vitro tumor cytotoxicity of leaf extracts from five Mauritian endemic medicinal plants, namely Acalypha integrifolia Willd (Euphorbiaceae), Labourdonnaisia glauca Bojer (Sapotaceae), Dombeya acutangula Cav. subsp. rosea Friedmann (Malvaceae), Gaertnera psychotrioides (DC.) Baker (Rubiaceae), and Eugenia tinifolia Lam (Myrtaceae). The cytotoxicities of the extracts were determined against six human cancer cell lines, including cervical adenocarcinoma, colorectal carcinoma, oesophageal adenocarcinoma, and oesophageal squamous cell carcinoma. The potent extracts were further investigated using cell cycle analysis and reverse phase protein array (RPPA) analysis. The antioxidant properties and polyphenolic profile of the potent extracts were also evaluated. Gas chromatography mass spectrometry (GC-MS) analyses revealed the presence of (+)-catechin and gallocatechin in E. tinifolia and L. glauca, while gallic acid was detected in A. integrifolia. L. glauca, A. integrifolia, and E. tinifolia were highly selective towards human oesophageal squamous cell carcinoma (KYSE-30) cells. L. glauca and E. tinifolia arrested KYSE- 30 cells in the G2/M phase, in a concentration-dependent manner. RPPA analysis indicated that the extracts may partly exert their tumor growth-inhibitory activity by upregulating the intracellular level of 5'AMP-activated kinase (AMPK). The findings highlight the potent antiproliferative activity of three Mauritian endemic leaf extracts against oesophageal squamous cell carcinoma and calls for further investigation into their chemotherapeutic application.
