RESUMO

BACKGROUND: Natural hazards are increasing in frequency and intensity due to climate change. Many of these natural disasters cannot be prevented; what may be reduced is the extent of the risk and negative impact on people and property. Research indicates that the 2019-2020 bushfires in Australia (also known as the "Black Summer Bushfires") resulted in significant psychological distress among Australians both directly and indirectly exposed to the fires. Previous intervention research suggests that communities impacted by natural hazards (eg, earthquakes, hurricanes, and floods) can benefit from interventions that integrate mental health and social support components within disaster preparedness frameworks. Research suggests that disaster-affected communities often prefer the support of community leaders, local services, and preexisting relationships over external supports, highlighting that community-based interventions, where knowledge stays within the local community, are highly beneficial. The Community-Based Disaster Mental Health Intervention (CBDMHI) is an evidence-based approach that aims to increase disaster preparedness, resilience, social cohesion, and social support (disaster-related help-seeking), and decrease mental health symptoms, such as depression and anxiety. OBJECTIVE: This research aims to gain insight into rural Australian's recovery needs post natural hazards, and to enhance community resilience in advance of future fires. Specifically, this research aims to adapt the CBDMHI for the rural Australian context and for bushfires and second, to assess the acceptability and feasibility of the adapted CBDMHI in a rural Australian community. METHODS: Phase 1 consists of qualitative interviews (individual or dyads) with members of the target bushfire-affected rural community. Analysis of these data will include identifying themes related to disaster preparedness, social cohesion, and mental health, which will inform the adaptation. An initial consultation phase is a key component of the adaptation process and, therefore, phase 2 will involve additional discussion with key stakeholders and members of the community to further guide adaptation of the CBDMHI to specific community needs, building on phase 1 inputs. Phase 3 includes identifying and training local community leaders in the adapted intervention. Following this, leaders will co-deliver the intervention. The acceptability and feasibility of the adapted CBDMHI within the community will be evaluated by questionnaires and semistructured interviews. Effectiveness will be evaluated by quantifying psychological distress, resilience, community cohesion, psychological preparedness, and help-seeking intentions. RESULTS: This study has received institutional review board approval and commenced phase 1 recruitment in October 2022. CONCLUSIONS: The study will identify if the adapted CBDMHI is viable and acceptable within a village in the Northern Tablelands of New South Wales, Australia. These findings will inform future scale-up in the broader rural Australian context. If this intervention is well received, the CBDMHI may be valuable for future disaster recovery and preparedness efforts in rural Australia. These findings may inform future scale-up in the broader rural Australian context. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/53454.

RESUMO

BACKGROUND: High-risk alcohol consumption among young adults frequently occurs in the presence of peers who are also drinking. A high-risk drinking situation may consist of particular social network members who have a primary association with drinking. Fine-grained approaches such as ecological momentary assessment (EMA) are growing in popularity for studying real-time social influence, but studies using these approaches exclusively rely on participant self-report. Passive indicators of peer presence using Bluetooth-based technology to detect real-time interactions have the potential to assist in the development of just-in-time interventions. OBJECTIVE: This study seeks to examine the feasibility and acceptability of using a Bluetooth-based sensor and smartphone app to measure social contact in real-world drinking situations. METHODS: Young adults (N=20) who drink heavily and report social drinking will be recruited from the community to participate in a 3-week EMA study. Using a social network interview, index participants will identify and recruit 3 of their friends to carry a Bluetooth beacon. Participants will complete a series of EMA reports on their own personal Android devices including random reports; morning reports; first-drink reports; and signal-contingent reports, which are triggered following the detection of a beacon carried by a peer participant. EMA will assess alcohol use and characteristics of the social environment, including who is nearby and who is drinking. For items about peer proximity and peer drinking, a customized peer list will be presented to participants. Feedback about the study protocol will be ascertained through weekly contact with both index and peer participants, followed by a qualitative interview at the end of the study. We will examine the feasibility and acceptability of recruitment, enrollment of participants and peers, and retention. Feasibility will be determined using indexes of eligibility, enrollment, and recruitment. Acceptability will be determined through participant enrollment and retention, protocol compliance, and participant-reported measures of acceptability. Feasibility and acceptability for peer participants will be informed by enrollment rates, latency to enrollment, compliance with carrying the beacon, and self-reported reasons for compliance or noncompliance with beacon procedures. Finally, EMA data about peer proximity and peer drinking will support the validity of the peer selection process. RESULTS: Participant recruitment began in February 2023, and enrollment was completed in December 2023. Results will be reported in 2025. CONCLUSIONS: The protocol allows us to examine the feasibility and acceptability of a Bluetooth-based sensor for the detection of social contact between index participants and their friends, including social interactions during real-world drinking situations. Data from this study will inform just-in-time adaptive interventions seeking to address drinking in the natural environment by providing personalized feedback about a high-risk social context and alerting an individual that they are in a potentially unsafe situation.

RESUMO

OBJECTIVE: A feasibility study to test the proposed methodology for a larger randomised control trial was conducted, investigating the comparative effectiveness of the two types of pressure management support surfaces with regards to healing pressure injuries (PI). A secondary objective was to provide insights into the user acceptability of the two types of pressure management support surfaces. METHOD: A randomised control feasibility study was conducted in a community health setting in Canberra, Australia. Patients aged ≥65 years with an existing Stage 2 PI who slept in a bed were eligible. Participants were randomised to either the active mattress group or the reactive mattress group for use on their bed. All participants received standard wound care by community nursing staff and were provided an air-flotation cushion for use when not in bed. Photographs were taken and used for blind assessment of wound healing. Secondary information was gathered through a survey regarding user acceptability of the support surfaces and changes in habits regarding PI prevention strategies. RESULTS: In total, five patients were recruited, with one passing away prior to mattress allocation. Results were inconclusive with regards to comparative effectiveness and user acceptability due to the small sample size; however, secondary data indicated an increasing implementation of PI prevention strategies. CONCLUSION: This study confirmed the need for further high quality research comparing reactive and active pressure mattresses. Trends indicate the importance of including education on PI prevention strategies to promote changes in behaviour. Changes to the proposed methodology will be made to increase recruitment in the primary study.

RESUMO

Conventionally, soil cadmium (Cd) measurements in the laboratory are expensive and time-consuming, involving complex processes of sample preparation and chemical analysis. This study aimed to identify the feasibility of using sensor data of visible near-infrared reflectance (Vis-NIR) spectroscopy and portable X-ray fluorescence spectrometry (PXRF) to estimate regional soil Cd concentration in a time- and cost-saving manner. The sensor data of Vis-NIR and PXRF, and Cd concentrations of 128 surface soils from Yunnan Province, China, were measured. Outer-product analysis (OPA) was used for synthesizing the sensor data and Granger-Ramanathan averaging (GRA) was applied to fuse the model results. Artificial neural network (ANN) models were built using Vis-NIR data, PXRF data, and OPA data, respectively. Results showed that: (1) ANN model based on PXRF data performed better than that based on Vis-NIR data for soil Cd estimation; (2) Fusion methods of both OPA and GRA had higher predictive power (R2) = 0.89, ratios of performance to interquartile range (RPIQ) = 4.14, and lower root mean squared error (RMSE) = 0.06, in ANN model based on OPA fusion; R2 = 0.88, RMSE = 0.06, and RPIQ = 3.53 in GRA model) than those based on either Vis-NIR data or PXRF data. In conclusion, there exists a great potential for the combination of OPA fusion and ANN to estimate soil Cd concentration rapidly and accurately.

RESUMO

BACKGROUND: This study aimed to investigate the safety and feasibility of indocyanine green near-infrared fluorescence (ICG-NIR) fluorescence-guided video-endoscopic inguinal lymphadenectomy (VEIL) for rectal cancer with inguinal lymph node metastasis (ILNM). METHODS: A retrospective analysis was conducted on 11 patients with rectal cancer who underwent ICG-NIR fluorescence-guided VEIL, assessing various parameters such as operation time, intraoperative bleeding, number of harvested lymph nodes, intraoperative and postoperative complications, and follow-up. RESULTS: Regarding surgical procedures for ILNM, unilateral surgery was performed in 7 cases (54.5%) and bilateral surgery in 4 cases (45.5%). Among these 15 ICG-NIR-guided VEIL surgeries in 11 patients, positive fluorescence visualization was achieved in 13 operations (86.7%). The median estimated blood loss was 10 ml, and the median operation time was 90 min. One case (6.7%) required conversion to open surgery. The median duration of the drain tube was 12 days, and the median length of postoperative hospital stay was 20 days. Postoperative complications were observed, including incisional infection in 2 cases (18.2%), lymphatic leakage in 5 cases (45.5%), urinary infection in 1 case (9.1%), and pneumonia in 3 cases (27.3%). Complications such as skin necrosis, lower limb venous thrombosis, lower limb swelling, or impaired movement were observed during the postoperative follow-up period. No cases of primary lesion, groin, or pelvic lymph node recurrence were observed. CONCLUSION: ICG-NIR fluorescence-guided VEIL is a safe and feasible surgical treatment for rectal cancer with ILNM. ICG fluorescence guidance holds promise as a more personalized and precise approach for VEIL in rectal cancer surgery.

RESUMO

BACKGROUND: No single technique of remnant pancreas reconstruction after pancreaticoduodenectomy (PD) has been demonstrated to be superior to the others in the prevention of post-operative pancreatic fistula (POPF), and the accumulation of surgical experience is closely related to the quality of this anastomosis. The aim of the current study was to evaluate the feasibility and patient outcomes of a simplified technique involving a single-layer continuous pancreaticojejunostomy (PJA) with Falciform ligament reinforcement that can be used with all types of pancreases. METHODS: A single-centre and single-surgeon study was performed. One hundred consecutive patients undergoing pancreatic resection with subsequent PJA using a novel technique performed by a single surgeon were included in the study. Patient demographics, pre-operative treatments, risk factors for POPF, and post-operative morbidity and mortality and long-term patient outcome were prospectively recorded and reported. RESULTS: From March 2018 to March 2022, 59 male and 41 female patients were included. 91 patients underwent PD for malignancy with 32 receiving neoadjuvant treatment. 59 patients were classified as intermediate/high risk for POPF according to validated fistula prediction models. There were 12 POPF Type B and 2 POPF Type C. The overall morbidity rate was 16% with no 90-day mortality. 3 patients underwent reoperation. The median length of hospitalisation was 12.6 days and 82% of eligible patients commenced and completed adjuvant chemotherapy. CONCLUSION: Single-layer continuous dunking PJA with Falciform ligament reinforcement is a simplified and feasible method for PJA with a low associated complication rate.

RESUMO

PURPOSE: The aim of this prospective study was to evaluate the tolerance and feasibility of using virtual reality headsets with patients during interventional radiology procedures. MATERIAL AND METHOD: In this single-center prospective study, the use of a virtual reality headset in addition to the usual analgesic and anxiolytic treatment was proposed to all patients presenting in the interventional radiology department from December 2020 to June 2022. Exclusion criteria were as follows: (1) patients with whom it was not possible to communicate (2) epileptic patients, (3) non-verbal patients, and (4) pregnant women. The main objective was to evaluate the safety of the procedure by screening complications during and after the procedure. The second objective was to evaluate feasibility, as defined by the number of patients using the helmet until the end of the procedure. Effectiveness (patient's self-evaluation of pain and anxiety), comfort, satisfaction, emotions felt, sense of security, and feeling of immersion were also evaluated. Caregivers completed a feedback questionnaire. RESULTS: Virtual reality headsets were offered to 100 patients, 9 of whom declined. Procedures were achieved in 93.5% of cases: 6/91 patients removed the headset before the end of the procedure. There were minor adverse events in 2/85 (2.3%) procedures (discomfort and nausea) and no major adverse events. 93.9% of patients found an overall benefit, and 90.2% would recommend virtual reality to another patient. 94.4% of caregivers were satisfied with the virtual reality equipment. The mean pain level was 2.5 ± 2.7 before the procedure, 3.3 ± 2.5 during the procedure, and 1.6 ± 2.7 after the procedure. Mean anxiety scores were 4.6 ± 2.9 before the procedure, 3.1 ± 2.7 during the procedure, and 1.1 ± 1.9 after the procedure. CONCLUSION: The use of virtual reality technology as a complement to traditional therapy for procedures under local anesthesia is feasible and safe in interventional radiology and can be beneficial for pain and anxiety management.

RESUMO

OBJECTIVE: We aimed to evaluate the feasibility and utility of an unsupervised testing mechanism, in which participants pick up a swab kit, self-test (unsupervised) and return the kit to an on-campus drop box, as compared with supervised self-testing at staffed locations. DESIGN: University SARS-CoV-2 testing cohort. SETTING: Husky Coronavirus Testing provided voluntary SARS-CoV-2 testing at a university in Seattle, USA. OUTCOME MEASURES: We computed descriptive statistics to describe the characteristics of the study sample. Adjusted logistic regression implemented via generalised estimating equations was used to estimate the odds of a self-swab being conducted through unsupervised versus supervised testing mechanisms by participant characteristics, including year of study enrolment, pre-Omicron versus post-Omicron time period, age, sex, race, ethnicity, affiliation and symptom status. RESULTS: From September 2021 to July 2022, we received 92 499 supervised and 26 800 unsupervised self-swabs. Among swabs received by the laboratory, the overall error rate for supervised versus unsupervised swabs was 0.3% vs 4%, although this declined to 2% for unsupervised swabs by the spring of the academic year. Results were returned for 92 407 supervised (5% positive) and 25 836 unsupervised (4%) swabs from 26 359 participants. The majority were students (79%), 61% were female and most identified as white (49%) or Asian (34%). The use of unsupervised testing increased during the Omicron wave when testing demand was high and stayed constant in spring 2022 even when testing demand fell. We estimated the odds of using unsupervised versus supervised testing to be significantly greater among those <25 years of age (p<0.001), for Hispanic versus non-Hispanic individuals (OR 1.2, 95% CI 1.0 to 1.3, p=0.01) and lower among individuals symptomatic versus asymptomatic or presymptomatic (0.9, 95% CI 0.8 to 0.9, p<0.001). CONCLUSIONS: Unsupervised swab collection permitted increased testing when demand was high, allowed for access to a broader proportion of the university community and was not associated with a substantial increase in testing errors.

RESUMO

OBJECTIVE: This study aimed to investigate the feasibility, safety, and efficacy of the neuroendoscopy-assisted entire-process visualization technique (NEAEVT) of ventricular puncture for external ventricular drainage. METHODS: Eighty-eight patients with cerebral hemorrhage who underwent unilateral ventricular puncture for external ventricular drainage in our hospital from June 2021 to June 2023 were analyzed. Patients were grouped according to puncture technique: NEAEVT (30 patients), freehand (30 patients), and laser-navigation-assisted (28 patients). Operation time, drainage tube placement, and catheter-related hemorrhage incidence were compared between the groups. RESULTS: Mean operation time significantly differed between the freehand, NEAEVT, and laser-assisted groups (17.07, 18.37, and 34.04 min, respectively; P <0.0001). The position of the drainage tube was optimal or adequate in all patients of the NEAEVT group; optimal/adequate positioning was achieved in 80% of the freehand group. No catheter-related hemorrhage occurred in the NEAEVT group. Three freehand group patients and 2 laser-assisted group patients experienced catheter-related hemorrhage. CONCLUSION: The NEAEVT of ventricular puncture is accurate and achieves ventricular drainage without significantly increasing surgical trauma, operation time, or incidence of hemorrhage.

RESUMO

The sequential extraction routes of biogenic materials from sewage sludge (SS) were investigated. Physical methods (ultrasound, heating) and chemical methods (sodium hydroxide, sodium carbonate) were used to extract extracellular polymeric substances (EPS) and alginate-like extracellular polymers (ALEs) from SS. The residues after extraction were further subjected to physical methods (heating) and chemical methods (sulfuric acid, sodium hydroxide) for protein extraction. A comparison was made between sequential extraction routes and direct extraction of biomaterials from sludge in terms of extraction quantity, material properties, and applicability. The results showed that sequential extraction of biomaterials is feasible. The highest extraction quantities were obtained when using sodium carbonate for EPS and ALE extraction and sodium hydroxide for protein, reaching 449.80 mg/gVSS, 109.78 mg/gVSS, and 5447.08 mg/L, respectively. Sequential extraction procedures facilitate the extraction of biomaterials. Finally, suitable extraction methods for different application scenarios were analyzed.

RESUMO

Effective communication about cancer diagnosis and prognosis in sub-Saharan African oncology settings is often challenged by the cancer-related shame and stigma patients and families experience. Enhancing empathic communication between health care providers, including physicians and nurses, and oncology patients and their families can not only reduce cancer stigma but also improve patient engagement, treatment satisfaction, and quality of life. To reduce lung cancer stigma, we adapted an evidence-based empathic communication skills training intervention to reduce patients' experience of stigma in Nigeria and conducted a pilot study examining the feasibility and acceptability of the empathic communication skills training. Thirty health care providers, recruited from University College Hospital, Ibadan, and Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, participated in a 2.25-hour didactic and experiential training session. Participant surveys were completed before and after the training. Overall, participants reported highly favorable training evaluations, with at least 85% of health care providers agreeing or strongly agreeing to survey items assessing training relevance, novelty, clarity, and facilitator effectiveness. Self-efficacy to communicate empathically with patients increased significantly from before-training (Mean [SD] = 3.93 [0.28]) to after-training (Mean [SD] = 4.55 [0.15]; t29 = 3.51, P < .05). Significant improvements were observed in health care provider reports of empathy toward lung cancer survivors and attitude toward lung cancer care as well as significant reductions in lung cancer blame were noted. The empathic communication skills training was feasible, well received by oncology clinicians in Nigeria, and demonstrated improvements in health care provider-reported outcomes from before- to after-training.

RESUMO

BACKGROUND: Post-operative atrial fibrillation (POAF) occurs in up to 40% of patients following coronary artery bypass grafting (CABG) and is associated with a higher risk of stroke and mortality. This study investigates how POAF may be mitigated by epicardial placement of aseptically processed human placental membrane allografts (HPMAs) before pericardial closure in CABG surgery. This study was conducted as a pilot feasibility study to collect preliminary for a forthcoming multi-center randomized controlled trial. METHODS: This retrospective observational study of patients undergoing CABG surgery excluded patients with pre-operative heart failure, chronic kidney disease, or a history of atrial fibrillation. The "treatment" group (n = 24) had three HPMAs placed epicardially following cardiopulmonary bypass decannulation but before partial pericardial approximation and chest closure. The only difference in clinical protocol for the control group (n = 54) was that they did not receive HPMA. RESULTS: HPMA-treated patients saw a significant, greater than four-fold reduction in POAF incidence compared to controls (35.2-8.3%, p = 0.0136). Univariate analysis demonstrated that HPMA treatment was associated with an 83% reduction in POAF (OR = 0.17, p = 0.0248). Multivariable analysis yielded similar results (OR = 0.07, p = 0.0156) after controlling for other covariates. Overall length of stay (LOS) between groups was similar, but ICU LOS trended lower with HPMA treatment (p = 0.0677). Post-operative inotrope and vasopressor requirements were similar among groups. There was no new-onset post-operative heart failure, stroke, or death reported up to thirty days in either group. CONCLUSIONS: Epicardial HPMA placement can be a simple intervention at the end of CABG surgery that may provide a new approach to reduce post-operative atrial fibrillation by modulating local inflammation, possibly reducing ICU and hospital stay, and ultimately improving patient outcomes.

RESUMO

Background: The gait analysis method that has been used in clinical practice to date is an optical tracking system (OTS) using a marker, but a markerless gait analysis (MGA) system is being developed because of the expensive cost and complicated examination of the OTS. To apply this MGA clinically, a comparative study of the MGA and OTS methods is necessary. The purpose of this study was to evaluate the compatibility between the OTS and the MGA methods and to evaluate the usefulness of the MGA system in actual clinical settings. Methods: From March 2021 to August 2021, 14 patients underwent gait analysis using the OTS and MGA system, and the spatiotemporal parameters and kinematic results obtained by the 2 methods were compared. To evaluate the practicality of the MGA system in an actual clinical setting, MGA was performed on 14 symptomatic children with idiopathic toe walking, who had been treated with a corrective cast, and the pre-cast and post-cast results were compared. For the OTS, the Motion Analysis Eagle system was used, and for MGA, DH Walk was used. Results: The spatiotemporal parameters showed no significant difference between the OTS and MGA system. The joint angle graphs of the kinematics along the sagittal plane showed similar shapes as a whole, with particularly high correlations in the hip and knee (pelvis: 29.4%, hip joint: 96.7%, knee joint: 94.9%, and ankle joint: 68.5%). A quantified comparison using the CORrelation and Analysis (CORA) score also showed high similarity between the 2 methods. The MGA results of pre-cast application and post-cast removal for children with idiopathic toe walking showed a statistically significant improvement in ankle dorsiflexion after treatment (p < 0.001). Conclusions: MGA showed a good correlation with the conventional OTS in terms of spatiotemporal parameters and kinematics. We demonstrated that ankle sagittal kinematics improved after treatment by corrective cast in children with idiopathic toe walking using the MGA method. Thus, after the improvement of a few limitations, the MGA system may soon be able to be clinically applied.

RESUMO

OBJECTIVE: The purpose of this proof-of-concept pilot study was to test the initial feasibility and limited efficacy of ArtSpective™ for perinatal substance use (PSU), a novel, arts-based intervention designed to decrease stigmatizing attitudes toward PSU. METHODS: Using a pre-post mixed methods quasi-experimental design, ArtSpective™ for PSU was pilot tested for proof of concept among a convenience sample of 11 undergraduate and graduate students with experience in maternal-infant nursing from a Midwestern U.S. nursing school. As a proof-of-concept pilot study, we evaluated feasibility (acceptability, demand, and implementation) and limited efficacy. Participants completed presurveys and postsurveys that included satisfaction items, demographic items, and an adapted version of the Attitudes About Drug Use in Pregnancy Scale and participated in a focus group. Focus group data were analyzed using constant comparative methods, and survey data were analyzed using descriptive statistics and Wilcoxon signed rank tests. RESULTS: Participants reported high demand and satisfaction with the intervention and provided recommendations to improve scalability. ArtSpective™ demonstrated significant improvement in stigma toward PSU (pre vs. post: p = .003; d = .633). CONCLUSION: ArtSpective™ for PSU demonstrated initial feasibility and limited efficacy for improving nurse attitudes toward PSU. Efforts are needed to further test this novel intervention, adapt it to augment existing educational interventions, and improve its scalability.

RESUMO

BACKGROUND: A growing number of older adults (ages 65+) live with Type 1 diabetes. Simultaneously, technologies such as continuous glucose monitoring (CGM) have become standard of care. There is thus a need to understand better the complex dynamics that promote use of CGM (and other care innovations) over time in this age group. Our aim was to adapt methods from systems thinking, specifically a participatory approach to system dynamics modeling called group model building (GMB), to model the complex experiences that may underlie different trajectories of CGM use among this population. Herein, we report on the feasibility, strengths, and limitations of this methodology. METHODS: We conducted a series of GMB workshops and validation interviews to collect data in the form of questionnaires, diagrams, and recordings of group discussion. Data were integrated into a conceptual diagram of the "system" of factors associated with uptake and use of CGM over time. We evaluate the feasibility of each aspect of the study, including the teaching of systems thinking to older adult participants. We collected participant feedback on positive aspects of their experiences and areas for improvement. RESULTS: We completed nine GMB workshops with older adults and their caregivers (N = 33). Each three-hour in-person workshop comprised: (1) questionnaires; (2) the GMB session, including both didactic components and structured activities; and (3) a brief focus group discussion. Within the GMB session, individual drawing activities proved to be the most challenging for participants, while group activities and discussion of relevant dynamics over time for illustrative (i.e., realistic but not real) patients yielded rich engagement and sufficient information for system diagramming. Study participants liked the opportunity to share experiences with peers, learning and enhancing their knowledge, peer support, age-specific discussions, the workshop pace and structure, and the systems thinking framework. Participants gave mixed feedback on the workshop duration. CONCLUSIONS: The study demonstrates preliminary feasibility, acceptability, and the value of GMB for engaging older adults about key determinants of complex health behaviors over time. To our knowledge, few studies have extended participatory systems science methods to older adult stakeholders. Future studies may utilize this methodology to inform novel approaches for supporting health across the lifespan.

RESUMO

BACKGROUND: BERT models have seen widespread use on unstructured text within the clinical domain. However, little to no research has been conducted into classifying unstructured clinical notes on the basis of patient lifestyle indicators, especially in Dutch. This article aims to test the feasibility of deep BERT models on the task of patient lifestyle classification, as well as introducing an experimental framework that is easily reproducible in future research. METHODS: This study makes use of unstructured general patient text data from HagaZiekenhuis, a large hospital in The Netherlands. Over 148 000 notes were provided to us, which were each automatically labelled on the basis of the respective patients' smoking, alcohol usage and drug usage statuses. In this paper we test feasibility of automatically assigning labels, and justify it using hand-labelled input. Ultimately, we compare macro F1-scores of string matching, SGD and several BERT models on the task of classifying smoking, alcohol and drug usage. We test Dutch BERT models and English models with translated input. RESULTS: We find that our further pre-trained MedRoBERTa.nl-HAGA model outperformed every other model on smoking (0.93) and drug usage (0.77). Interestingly, our ClinicalBERT model that was merely fine-tuned on translated text performed best on the alcohol task (0.80). In t-SNE visualisations, we show our MedRoBERTa.nl-HAGA model is the best model to differentiate between classes in the embedding space, explaining its superior classification performance. CONCLUSIONS: We suggest MedRoBERTa.nl-HAGA to be used as a baseline in future research on Dutch free text patient lifestyle classification. We furthermore strongly suggest further exploring the application of translation to input text in non-English clinical BERT research, as we only translated a subset of the full set and yet achieved very promising results.

RESUMO

INTRODUCTION: Patients with proctocolectomy and ileal pouch-anal anastomosis (PC-IPAA) face unique challenges in managing prostate cancer due to their hostile abdomens and heightened small bowel mucosa radiosensitivity. In such cases, external beam radiation therapy (EBRT) is contraindicated, and while brachytherapy provides a safer option, its oncologic effectiveness is limited. The Single-Port Transvesical Robot-Assisted Radical Prostatectomy (SP TV-RARP) offers promise by avoiding the peritoneal cavity. Our study aims to evaluate its feasibility and outcomes in patients with PC-IPAA. METHODS: A retrospective evaluation was done on patients with PC-IPAA who had undergone SP TV-RARP from June 2020 to June 2023 at a high-volume center. Outcomes and clinicopathologic variables were analyzed. RESULTS: Eighteen patients underwent SP TV-RARP without experiencing any complications. The median hospital stay was 5.7 h, with 89% of cases discharged without opioids. Foley catheters were removed in an average of 5.5 days. Immediate urinary continence was seen in 39% of the patients, rising to 76 and 86% at 6- and 12-month follow-ups. Half of the cohort had non-organ confined disease on final pathology. Two patients with ISUP GG3 and GG4 exhibited detectable PSA post-surgery and required systemic therapy; both had SVI, multifocal ECE, and large cribriform pattern. Positive surgical margins were found in 44% of cases, mostly Gleason pattern 3, unifocal, and limited. After 11.1 months of follow-up, no pouch failure or additional BCR cases were found. CONCLUSION: Patients with PC-IPAA often exhibit aggressive prostate cancer features and may derive the greatest benefit from surgical interventions, particularly given that radiation therapy is contraindicated. SP TV-RARP is a safe option for this group, reducing the risk of bowel complications and promoting faster recovery.

RESUMO

BACKGROUND: Chronic pain affects tens of millions of US adults and continues to rise in prevalence. Nonpharmacologic behavioral pain treatments are greatly needed and yet are often inaccessible, particularly in settings where medication prescribing is prioritized. OBJECTIVE: This study aims to test the feasibility of a live-instructor, web-based 1-session pain relief skills class in an underserved and potentially at-risk population: people with chronic pain prescribed methadone or buprenorphine either solely for pain or for comorbid opioid use disorder (OUD). METHODS: This is a national, prospective, single-arm, uncontrolled feasibility trial. The trial is untethered from medical care; to enhance participants' willingness to join the study, no medical records or drug-monitoring records are accessed. At least 45 participants will be recruited from outpatient pain clinics and from an existing research database of individuals who have chronic pain and are taking methadone or buprenorphine. Patient-reported measures will be collected at 6 time points (baseline, immediately post treatment, 2 weeks, and months 1-3) via a web-based platform, paper, or phone formats to include individuals with limited internet or computer access and low literacy skills. At baseline, participants complete demographic questions and 13 study measures (Treatment Expectations, Body Pain Map, Medication Use, Pain Catastrophizing Scale [PCS], Patient-Reported Outcomes Measurement Information System [PROMIS] Measures, and Opioid Craving Scale). Immediately post treatment, a treatment satisfaction and acceptability measure is administered on a 0 (very dissatisfied) to 10 (completely satisfied) scale, with 3 of these items being the primary outcome (perceived usefulness, participant satisfaction, and likelihood of using the skills). At each remaining time point, the participants complete all study measures minus treatment expectations and satisfaction. Participants who do not have current OUD will be assessed for historical OUD, with presence of OUD (yes or no), and history of OUD (yes or no) reported separately. Feasibility threshold is set as an overall group treatment satisfaction rating of 8 of 10. In-depth qualitative interviews will be conducted with about 10 participants to obtain additional data on patient perceptions, satisfactions, needs, and wants. To assess preliminary efficacy, we will examine changes in pain catastrophizing, pain intensity, pain bothersomeness, sleep disturbance, pain interference, depression, anxiety, physical function, global impression of change, and opioid craving at 1 month post treatment. RESULTS: This project opened to enrollment in September 2021 and completed the recruitment in October 2023. The data collection was completed in February 2024. Results are expected to be published in late 2024. CONCLUSIONS: Results from this trial will inform the feasibility and preliminary efficacy of Empowered Relief in this population and will inform the design of a future randomized controlled trial testing web-based Empowered Relief in chronic pain and comorbid OUD.

RESUMO

BACKGROUND AND OBJECTIVES: Current practice in clinical neurophysiology is limited to short recordings with conventional EEG (days) that fail to capture a range of brain (dys)functions at longer timescales (months). The future ability to optimally manage chronic brain disorders, such as epilepsy, hinges upon finding methods to monitor electrical brain activity in daily life. We developed a device for full-head subscalp EEG (Epios) and tested here the feasibility to safely insert the electrode leads beneath the scalp by a minimally invasive technique (primary outcome). As secondary outcome, we verified the noninferiority of subscalp EEG in measuring physiologic brain oscillations and pathologic discharges compared with scalp EEG, the established standard of care. METHODS: Eight participants with pharmacoresistant epilepsy undergoing intracranial EEG received in the same surgery subscalp electrodes tunneled between the scalp and the skull with custom-made tools. Postoperative safety was monitored on an inpatient ward for up to 9 days. Sleep-wake, ictal, and interictal EEG signals from subscalp, scalp, and intracranial electrodes were compared quantitatively using windowed multitaper transforms and spectral coherence. Noninferiority was tested for pairs of neighboring subscalp and scalp electrodes with a Bland-Altman analysis for measurement bias and calculation of the interclass correlation coefficient (ICC). RESULTS: As primary outcome, up to 28 subscalp electrodes could be safely placed over the entire head through 1-cm scalp incisions in a ∼1-hour procedure. Five of 10 observed perioperative adverse events were linked to the investigational procedure, but none were serious, and all resolved. As a secondary outcome, subscalp electrodes advantageously recorded EEG percutaneously without requiring any maintenance and were noninferior to scalp electrodes for measuring (1) variably strong, stage-specific brain oscillations (alpha in wake, delta, sigma, and beta in sleep) and (2) interictal spikes peak-potentials and ictal signals coherent with seizure propagation in different brain regions (ICC >0.8 and absence of bias). DISCUSSION: Recording full-head subscalp EEG for localization and monitoring purposes is feasible up to 9 days in humans using minimally invasive techniques and noninferior to the current standard of care. A longer prospective ambulatory study of the full system will be necessary to establish the safety and utility of this innovative approach.

RESUMO

BACKGROUND: Smartbands can be used to detect cigarette smoking and deliver real time smoking interventions. Brief mindfulness interventions have been found to reduce smoking. OBJECTIVE: This single arm feasibility trial used a smartband to detect smoking and deliver brief mindfulness exercises. METHODS: Daily smokers who were motivated to reduce their smoking wore a smartband for 60 days. For 21 days, the smartband monitored, detected and notified the user of smoking in real time. After 21 days, a 'mindful smoking' exercise was triggered by detected smoking. After 28 days, a 'RAIN' (recognize, allow, investigate, nonidentify) exercise was delivered to predicted smoking. Participants received mindfulness exercises by text message and online mindfulness training. Feasibility measures included treatment fidelity, adherence and acceptability. RESULTS: Participants (N=155) were 54% female, 76% white non-Hispanic, and treatment starters (n=115) were analyzed. Treatment fidelity cutoffs were met, including for detecting smoking and delivering mindfulness exercises. Adherence was mixed, including moderate smartband use and low completion of mindfulness exercises. Acceptability was mixed, including high helpfulness ratings and mixed user experiences data. Retention of treatment starters was high (81.9%). CONCLUSIONS: Findings demonstrate the feasibility of using a smartband to track smoking and deliver quit smoking interventions contingent on smoking.
