Targeted precision cryotherapy for acne vulgaris.

BACKGROUND: Acne vulgaris poses a significant dermatological challenge, necessitating alternative treatments due to limitations and side effects associated with current therapies. This pilot clinical trial investigated the feasibility and efficacy of precision cryotherapy for acne vulgaris. METHODS: A total of 20 volunteers underwent targeted precision cryotherapy using a carbon dioxide-based device. Treatment outcomes were assessed using various parameters, including Investigator Global Assessment (IGA) score, acne lesion count, erythema index (EI), global evaluation score, and participant satisfaction. Safety monitoring included adverse event reporting and physical examination. RESULTS: Precision cryotherapy demonstrated a significant reduction (90.25%) in the acne lesion count by week 4, with clinical improvement indicated by IGA score reduction (p < 0.001). The EI showed notable improvements at weeks 1, 2, and 4. The global evaluation score demonstrated a 75%-100% clinical improvement at Visit 4. Participants reported high satisfaction (6.75 ± 0.79) with the procedure. No adverse event or discomfort was reported. CONCLUSION: Precision cryotherapy effectively improved acne lesions, which was safe and satisfactory for participants. These findings suggest its potential as an alternative therapeutic modality, especially for populations with limited treatment options. Further research is needed to validate the results and explore underlying mechanisms.

Feasibility and Acceptability Study of a Culturally Adapted Web-Based Intervention to Reduce Suicidal Ideation for Syrian Asylum Seekers and Refugees in the United Kingdom: Protocol for a Mixed Methods Study.

BACKGROUND: The war in Syria has displaced over 6.8 million people, more than any other conflict since the Second World War. As a result, Syrian asylum seekers and refugees have experienced several life-changing events, resulting in high rates of anxiety, depression, posttraumatic stress disorder, and suicidal ideation (SI). To address the treatment gap and reduce the burden of help-seeking, a web-based intervention to reduce SI developed for general populations was culturally adapted for and with Syrian asylum seekers and refugees in the United Kingdom. The study revealed the importance of understanding their lived experience with migration and the acculturative process in providing treatment for SI. This study will now assess the feasibility and acceptability of the culturally adapted intervention for this population. OBJECTIVE: The first phase of the study will include recruiting participants and delivering the web-based intervention (1) to assess the feasibility of meeting recruitment goals and recruitment rates and (2) to assess the feasibility of outcome measures. The second phase of the study will include one-to-one semistructured interviews (1) to assess the suitability of the culturally adapted intervention in terms of recruitment and adherence rates and barriers and facilitators to engagement and (2) to assess the acceptability of the intervention in terms of its cultural relevance and appropriateness. METHODS: This is a protocol for a single-group, noncontrolled, mixed methods feasibility and acceptability study of a culturally adapted web-based intervention to reduce SI for Syrian asylum seekers and refugees in the United Kingdom. The study will assess the feasibility of recruitment goals, recruitment rates, adherence rates, and outcome measures using individual participant tracking forms, which will be analyzed quantitatively. The suitability and acceptability of the intervention will be assessed using one-to-one semistructured interviews with 12 participants who completed the intervention, which will be analyzed qualitatively. RESULTS: Recruitment began in February 2024 and will run until 30 participants are recruited to the study or until the end of July 2024. Thus far, 19 participants have provided informed consent, 16 were eligible and enrolled, and 12 have completed a postintervention interview. No data have been analyzed. The study, including the write-up period, is expected to end in December 2024. CONCLUSIONS: Despite experiencing several stressors related to forced displacement and high rates of mental health issues, access to treatment is still limited for Syrian asylum seekers and refugees in the United Kingdom. To address the treatment gap and reduce the burden of help-seeking, a web-based intervention to reduce SI was culturally adapted in collaboration with Syrian asylum seekers and refugees in the United Kingdom. This study will now assess the feasibility and acceptability of the intervention and culturally appropriate recruitment strategies.

Image directed redesign of bladder cancer treatment pathways: the BladderPath RCT.

Background: Transurethral resection of bladder tumour has been the mainstay of bladder cancer staging for > 60 years. Staging inaccuracies are commonplace, leading to delayed treatment of muscle-invasive bladder cancer. Multiparametric magnetic resonance imaging offers rapid, accurate and non-invasive staging of muscle-invasive bladder cancer, potentially reducing delays to radical treatment. Objectives: To assess the feasibility and efficacy of the introducing multiparametric magnetic resonance imaging ahead of transurethral resection of bladder tumour in the staging of suspected muscle-invasive bladder cancer. Design: Open-label, multistage randomised controlled study in three parts: feasibility, intermediate and final clinical stages. The COVID pandemic prevented completion of the final stage. Setting: Fifteen UK hospitals. Participants: Newly diagnosed bladder cancer patients of age ≥ 18 years. Interventions: Participants were randomised to Pathway 1 or 2 following visual assessment of the suspicion of non-muscle-invasive bladder cancer or muscle-invasive bladder cancer at the time of outpatient cystoscopy, based upon a 5-point Likert scale: Likert 1-2 tumours considered probable non-muscle-invasive bladder cancer; Likert 3-5 possible muscle-invasive bladder cancer. In Pathway 1, all participants underwent transurethral resection of bladder tumour. In Pathway 2, probable non-muscle-invasive bladder cancer participants underwent transurethral resection of bladder tumour, and possible muscle-invasive bladder cancer participants underwent initial multiparametric magnetic resonance imaging. Subsequent therapy was determined by the treating team and could include transurethral resection of bladder tumour. Main outcome measures: Feasibility stage: proportion with possible muscle-invasive bladder cancer randomised to Pathway 2 which correctly followed the protocol. Intermediate stage: time to correct treatment for muscle-invasive bladder cancer. Results: Between 31 May 2018 and 31 December 2021, of 638 patients approached, 143 participants were randomised; 52.1% were deemed as possible muscle-invasive bladder cancer and 47.9% probable non-muscle-invasive bladder cancer. Feasibility stage: 36/39 [92% (95% confidence interval 79 to 98%)] muscle-invasive bladder cancer participants followed the correct treatment by pathway. Intermediate stage: median time to correct treatment was 98 (95% confidence interval 72 to 125) days for Pathway 1 versus 53 (95% confidence interval 20 to 89) days for Pathway 2 [hazard ratio 2.9 (95% confidence interval 1.0 to 8.1)], p = 0.040. Median time to correct treatment for all participants was 37 days for Pathway 1 and 25 days for Pathway 2 [hazard ratio 1.4 (95% confidence interval 0.9 to 2.0)]. Limitations: For participants who underwent chemotherapy, radiotherapy or palliation for multiparametric magnetic resonance imaging-diagnosed stage T2 or higher disease, it was impossible to conclusively know whether these were correct treatments due to the absence of histopathologically confirmed muscle invasion, this being confirmed radiologically in these cases. All patients had histological confirmation of their cancers. Due to the COVID-19 pandemic, we were unable to realise the final stage. Conclusion: The multiparametric magnetic resonance imaging-directed pathway led to a substantial 45-day reduction in time to correct treatment for muscle-invasive bladder cancer, without detriment to non-muscle-invasive bladder cancer participants. Consideration should be given to the incorporation of multiparametric magnetic resonance imaging ahead of transurethral resection of bladder tumour into the standard pathway for all patients with suspected muscle-invasive bladder cancer. The improved decision-making accelerated time to treatment, even though many patients subsequently needed transurethral resection of bladder tumour. A proportion of patients can avoid transurethral resection of bladder tumour completely, reducing costs and morbidity, given the much lower cost of magnetic resonance imaging and biopsy compared to transurethral resection of bladder tumour. Future work: Further work to cross-correlate with the recently developed Vesical Imaging-Reporting and Data System will improve accuracy and aid dissemination. Longer follow-up to examine the effect of the pathway on outcomes is also required. Incorporation of liquid deoxyribonucleic acid-based biomarkers may further improve the quality of decision-making and should also be investigated further.

The BladderPath trial explored how to accelerate diagnosis and avoid unnecessary surgery for patients with bladder cancer which had grown into the muscle wall of the bladder, referred to as muscle-invasive bladder cancer. Following initial outpatient diagnosis, bladder cancer patients currently undergo inpatient or day-case surgical tumour removal using a telescope (transurethral resection of bladder tumour). This surgery is fundamental to the treatment of early bladder cancer (non-muscle-invasive). However, for muscle-invasive disease, the main role of transurethral resection of bladder tumour is to confirm that the tumour has grown into the bladder muscle, and this is often inaccurate; the actual correct treatment for muscle-invasive bladder cancer patients should include chemotherapy, radiotherapy and/or bladder removal. For these patients, having transurethral resection of bladder tumour may delay this correct treatment and impact survival. Additionally, for patients determined to need palliative care due to advanced disease, the transurethral resection of bladder tumour may represent over-treatment. A magnetic resonance imaging scan with contrast agent (called multiparametric magnetic resonance imaging) gives a clearer picture of the bladder than normal scans, allowing distinction between invasive and non-invasive tumours. The BladderPath trial investigated adding multiparametric magnetic resonance imaging for patients with suspected muscle-invasive bladder cancer and the effect on treatment times. Subsequent therapy could include transurethral resection of bladder tumour if clinically determined as necessary by the treating team. Trial participants were randomly allocated either to the standard pathway (Pathway 1: all underwent transurethral resection of bladder tumour) or to a new pathway (Pathway 2). In Pathway 2, urologists conducting the initial outpatient diagnostic bladder inspections used a scale to assess whether tumours appeared to be either probably non-muscle-invasive or possibly muscle-invasive. Participants whose tumours appeared possibly muscle-invasive had initial multiparametric magnetic resonance imaging as their next investigation instead of transurethral resection of bladder tumour. We then compared the duration of time from initial diagnosis to receiving the correct treatment for participants in each pathway. Of the 143 participants, 75 (52.1%) were diagnosed as possibly muscle invasive. In Pathway 1, the duration for half of the participants in the group to have received their correct treatment for muscle-invasive bladder cancer was 98 days, which reduced to 53 days in Pathway 2. Furthermore, the duration for half of all the participants in the two groups to have received their correct treatment was 37 days for Pathway 1 and 31 days for Pathway 2. In summary, use of initial multiparametric magnetic resonance imaging in suspected muscle-invasive bladder cancer participants substantially reduced the time to correct treatment (surgery, radiotherapy, chemotherapy or instigation of palliative care) and avoided unnecessary surgery. There was no negative impact on participants with non-invasive disease. Adopting multiparametric magnetic resonance imaging into the pathway ahead of transurethral resection of bladder tumour for patients with suspected muscle-invasive bladder cancer is recommended.

Thoracoscopic three-port single versus multiple intercostal for radical resection of esophageal cancer: a retrospective analysis.

BACKGROUND: The purpose of this retrospective study was to compare the safety and feasibility of single-intercostal totally minimally invasive Ivor Lewis esophagectomy (MIIE) with those of multiple-intercostal MIIE. METHODS: Between January 2016 and December 2022, clinical data were collected for 528 patients who successfully underwent totally minimally invasive esophagectomy. Among these patients, 294 underwent MIIE, with 200 undergoing the single-intercostal approach and 94 undergoing the multiple-intercostal approach. Propensity score matching (PSM) was applied to the cohort of 294 patients. Subsequently, perioperative outcomes and other pertinent clinical data were analyzed retrospectively. RESULTS: A total of 294 patients were subjected to PSM, and 89 groups of patient data (178 persons in total) were well balanced and included in the follow-up statistics. Compared to the multiple intercostal group, the single intercostal group had a shorter operative time (280 min vs. 310 min; p < 0.05). Moreover, there was no significant difference in the incidence of major perioperative complications (p > 0.05). The total number of lymph nodes sampled (25.30 vs. 27.55, p > 0.05) and recurrent laryngeal nerve lymph nodes sampled on the both sides (p > 0.05) did not significantly differ. The single intercostal group had lower postoperative long-term usage of morphine (0,0-60 vs. 20,20-130; p < 0.01), total temporary addition (10,0-30 vs. 20,20-40; p < 0.01) and temporary usage in the first 3 days after surgery (0,0-15 vs. 10,10-20; p < 0.01) than did the multicostal group.There were no significant differences in age, sex, tumor location or extent of lymphadenectomy or in the clinical factors between the single-intercostal group (p > 0.05). CONCLUSIONS: Both techniques can be used for the treatment of esophageal cancer. Compared to multiple intercostal MIIE, the feasibility of which has been proven internationally, the single intercostal technique can also be applied to patients of different age groups and sexes and with different tumor locations. It can provide surgeons with an additional surgical option. TRIAL REGISTRATION: This study was retrospectively registered by the Ethics Committee of the Second Affiliated Hospital of Zhejiang University School of Medicine, and written informed consent was exempted from ethical review. The registration number was 20,230,326. The date of registration was 2023.03.26.

Radiomics of multi-parametric MRI for the prediction of lung metastasis in soft-tissue sarcoma: a feasibility study.

PURPOSE: To investigate the value of multi-parametric MRI-based radiomics for preoperative prediction of lung metastases from soft tissue sarcoma (STS). METHODS: In total, 122 patients with clinicopathologically confirmed STS who underwent pretreatment T1-weighted contrast-enhanced (T1-CE) and T2-weighted fat-suppressed (T2FS) MRI scans were enrolled between Jul. 2017 and Mar. 2021. Radiomics signatures were established by calculating and selecting radiomics features from the two sequences. Clinical independent predictors were evaluated by statistical analysis. The radiomics nomogram was constructed from margin and radiomics features by multivariable logistic regression. Finally, the study used receiver operating characteristic (ROC) and calibration curves to evaluate performance of radiomics models. Decision curve analyses (DCA) were performed to evaluate clinical usefulness of the models. RESULTS: The margin was considered as an independent predictor (p < 0.05). A total of 4 MRI features were selected and used to develop the radiomics signature. By incorporating the margin and radiomics signature, the developed nomogram showed the best prediction performance in the training (AUCs, margin vs. radiomics signature vs. nomogram, 0.609 vs. 0.909 vs. 0.910) and validation (AUCs, margin vs. radiomics signature vs. nomogram, 0.666 vs. 0.841 vs. 0.894) cohorts. DCA indicated potential usefulness of the nomogram model. CONCLUSIONS: This feasibility study evaluated predictive values of multi-parametric MRI for the prediction of lung metastasis, and proposed a nomogram model to potentially facilitate the individualized treatment decision-making for STSs.

Feasibility of in-home monitoring for people with glaucoma: the I-TRAC mixed-methods study.

Background: Glaucoma is a chronic disease of the optic nerve and a leading cause of severe visual loss in the UK. Once patients have been diagnosed, they need regular monitoring at hospital eye services. Recent advances in technology mean patients with glaucoma can now monitor their disease at home. This could be more convenient for patients and potentially reduce costs and increase capacity for the NHS. However, it is uncertain whether self-monitoring would be acceptable or possible for patients with glaucoma. Objectives: The objectives were to: identify which patients are most appropriate for home monitoring; understand views of key stakeholders (patients, clinicians, researchers) on whether home glaucoma monitoring is feasible and acceptable; develop a conceptual framework for the economic evaluation of home glaucoma monitoring; and explore the need for and provide evidence on the design of a future study to evaluate the clinical and cost-effectiveness of digital technologies for home monitoring of glaucoma. Design: In-home Tracking of glaucoma: Reliability, Acceptability, and Cost (I-TRAC) was a multiphase mixed-methods feasibility study with key components informed by theoretical and conceptual frameworks. Setting: Expert glaucoma specialists in the UK recruited through professional glaucoma societies; study site staff and patient participants recruited through three UK hospital eye services (England, Scotland, Northern Ireland); and UK research teams recruited though existing networks. Intervention: Home tonometer that measures intraocular pressure and a tablet computer with a visual function application. Patients were asked to use the technology weekly for 12 weeks. Results: Forty-two patients were recruited. Retention and completion of follow-up procedures was successful, with 95% (n = 40) completing the 3-month follow-up clinic visits. Adherence to the interventions was generally high [adherence to both devices (i.e. ≥ 80% adherence) was 55%]. Overall, patients and healthcare professionals were cautiously optimistic about the acceptability of digital technologies for home monitoring of patients with glaucoma. While most clinicians were supportive of the potential advantages glaucoma home monitoring could offer, concerns about the technologies (e.g. reliability and potential to miss disease progression) and how they would fit into routine care need to be addressed. Additionally, clarity is required on defining the ideal population for this intervention. Plans for how to evaluate value for money in a future study were also identified. However, the study also highlighted several unknowns relating to core components of a future evaluative study that require addressing before progression to a definitive effectiveness trial. Limitations: The main limitation relates to our sample and its generalisability, for example, the over-representation of educated persons of white ethnicity who were generally experienced with technology and research motivated. Conclusions: The In-home Tracking of glaucoma: Reliability, Acceptability, and Cost study has demonstrated 'cautious optimism' when considering patients' and healthcare professionals' views on the acceptability of digital technologies for home monitoring of patients with glaucoma. However, the study also highlighted several unknowns relating to the research question and design of a future evaluative study that require addressing before progression to a randomised controlled trial. Future work: Further research is required to determine the appropriate population (i.e. low vs. high risk of progression) and further refine the intervention components and delivery for planning of future evaluation studies.

The In-home Tracking of glaucoma: Reliability, Acceptability, and Cost study explored whether glaucoma patients who would normally be monitored in hospital could do some monitoring themselves at home, and whether self-monitoring at home would be acceptable or possible for them. We delivered In-home Tracking of glaucoma: Reliability, Acceptability, and Cost in four phases by: Surveying expert glaucoma specialists to understand which patients would benefit most from home monitoring. Providing glaucoma patients with an iPad tablet and a device which measures eye pressure to use once a week for 3 months. The patients who participated and the clinical staff delivering the study were interviewed about their experiences. Interviewing researchers with experience of running large studies testing digital technologies to monitor patients' health at home to understand challenges. Reviewing other researchers' work and comparing it with ours to help us understand whether home monitoring of glaucoma could be good value for money. Overall, patients and healthcare professionals were cautiously optimistic about the digital technologies for home monitoring of glaucoma. Most patient participants were able to use the technologies, and half told us they preferred home monitoring. Most clinicians recognised the potential advantages of glaucoma home monitoring but had concerns about the technologies (specifically reliability and the risk of missing disease progression) and how they would fit into routine care. Plans for how to evaluate value for money in a future study were identified. The study did not aim to identify whether the digital technology was better than what happens currently; a different study design with many more patients would be required to answer that question. The study did identify several important questions to answer before designing a future larger study; for example, how to ensure diverse patient participation. These questions should be the focus of future research in this area.

Extraperitoneal single-port robot-assisted radical prostatectomy: Short-term outcomes and technique description.

PURPOSE: We evaluated the feasibility, safety, and learning curve of extraperitoneal single-port robot-assisted radical prostatectomy (SP-RARP) and introduced innovative surgical techniques to maintain the instrument positions during the procedures. MATERIALS AND METHODS: A cohort of 100 patients underwent extraperitoneal SP-RARP at our institution from December 2021 to April 2023. The procedures were performed by an experienced urology surgeon utilizing two surgical techniques for dissecting the posterior aspect of the prostate-"changing instrument roles" and "using camera inversion"-to prevent positional shifts between the camera and instruments. RESULTS: The mean operation time for SP-RARP was 93.58 minutes, and the mean console time was 65.16 minutes. The mean estimated blood loss during the procedures was 109.30 mL. No cases necessitated conversion to multi-port robot, laparoscopy, or open surgery, and there were no major complications during the hospital stay or in the short-term follow-up. Early outcomes of post-radical prostatectomy indicated a biochemical recurrence rate of 4.0% over a mean follow-up duration of 6.40 months, with continence and potency recovery rates of 92.3% and 55.8%, respectively. Analysis of the learning curve showed no significant differences in operation time, console time, and positive surgical margin rates between the initial and latter 50 cases. CONCLUSIONS: Extraperitoneal SP-RARP is a feasible and safe option for the treatment of localized prostate cancer in skilled hands. Continued accrual of cases is essential for future comparisons of SP-RARP with multiport approaches.

Implementation of health-promoting retail initiatives in the Healthier Choices in Supermarkets Study-qualitative perspectives from a feasibility study.

BACKGROUND: Improving food environments like supermarkets has the potential to affect customers' health positively. Scholars suggest researchers and retailers collaborate closely on implementing and testing such health-promoting interventions, but knowledge of the implementation of such interventions is limited. We explore the implementation of four health-promoting food retail initiatives selected and developed by a partnership between a research institution, a large retail group, and a non-governmental organisation. METHODS: The four initiatives included downsizing of bags for pick'n' mix sweets and soda bottles at the check-out registers, shelf tags promoting healthier breakfast cereal options, and replacing a complimentary bun with a banana offered to children. The initiatives were implemented for 6 weeks (or longer if the store manager allowed it) in one store in Copenhagen, Denmark. Data were collected through observations, informal interviews with customers, and semi-structured interviews with retailers. We conducted a thematic analysis of transcripts and field notes inspired by process evaluation concepts and included quantitative summaries of selected data. RESULTS: Two out of four initiatives were not implemented as intended. The implementation was delayed due to delivery issues, which also resulted in soda bottles not being downsized as intended. The maintenance of the shelf tags decreased over time. Retailers expressed different levels of acceptability towards the initiatives, with a preference for the complimentary banana for children. This was also the only initiative noticed by customers with both positive and negative responses. Barriers and facilitators of implementation fell into three themes: Health is not the number one priority, general capacity of retailers, and influence of customers and other stakeholders on store operation. CONCLUSIONS: The retailers' interests, priorities, and general capacity influenced the initiative implementation. Retailers' acceptability of the initiatives was mixed despite their involvement in the pre-intervention phase. Our study also suggests that customer responses towards health-promoting initiatives, as well as cooperation with suppliers and manufacturers in the development phase, may be determining to successful implementation. Future studies should explore strategies to facilitate implementation, which can be applied prior to and during the intervention.

Special-form radial collateral artery perforator flaps for the reconstruction of complex hand defects.

BACKGROUND: The reconstruction of complex wounds of the hand still has challenges in achieving aesthetic, functional and sensory recovery. We presented our experience of using the polyfoliate and chimeric radial collateral artery perforator flaps (RCAPF) to repair complex hand defects, aiming to explore the feasibility of special-form RCAPFs in hand coverage and enhance the comprehension of their respective indications. METHODS: From June 2014 to March 2021, 26 cases (19 males and 7 females, mean 44.4 years) underwent defect and sensation reconstruction of their hands with special-form RCAPFs, which manifested as multiple adjacent or irregular single wounds and composite tissue defects complicated with a degree of nerve injury. The clinical effects of the free RCAPFs were evaluated by integrating the postoperative and long-term follow-up outcomes of all cases. RESULTS: Altogether 8 polyfoliate flaps, 17 chimeric flaps and 1 polyfoliate-chimeric flap were harvested. Of them, 23 flaps survived uneventfully in one stage. Venous congestion occurred in 3 cases, two of which survived through vascular exploration and another one was finally repaired by the contralateral RCAPF. The follow-up results showed that the appearance of both the recipient and donor sites mostly recovered satisfactory. All the bone flaps properly healed. The BMRC sensory evaluation results of all skin flaps were S4 in 8 flaps, S3 in 18 flaps, and S2 in 9 flaps. CONCLUSIONS: The free RCAPFs can be designed in various forms with a reliable blood supply, contributing to reconstructing simple and multiple wounds of the hand with or without bone defects and dead space.

[Feasibility and safety study of building a friendly management model for elderly critically ill patients based on geriatric intensive care unit: a prospective controlled study].

OBJECTIVE: To explore the feasibility and safety of integrating the geriatric intensive care unit (GICU) into the friendly management model of the elderly critically ill patients. METHODS: A prospective controlled study was conducted. Patients with elderly critically ill admitted to the GICU and the general intensive care unit (ICU) of Jintan First People's Hospital of Changzhou from December 2021 to May 2023 were enrolled. Patients in the ICU group received the traditional intensive care and nursing mode. In addition to the ICU group basic medical care measures, the patients in the GICU group were treated with friendly management models such as flexible visitation, diagnosis and treatment environment optimization, caring diagnosis and treatment, and family participation in hospice care according to their condition assessment. The gender, age, main diagnosis, and acute physiology and chronic health evaluation II (APACHE II) at admission were recorded and compared between the two groups. During the treatment period, the incidence of nosocomial infection, unplanned extubation, falling out of bed/fall, unexpected readmission to ICU/GICU, and ICU/GICU mortality, the incidence of post-intensive care syndrome (PICS), the satisfaction rate of patients/families with medical care, and the satisfaction rate of patients/families with diagnosis and treatment environment were recorded and compared between the two groups. RESULTS: According to the admission criteria for ICU and GICU, as well as the willingness of the patients and/or their families, a total of 59 patients were finally included in the ICU group, and 48 patients were enrolled in the GICU group. There were no significantly differences in gender, age, main diagnosis and APACHE II score between the two groups, and there were comparability. There were no significantly differences in the incidence of adverse events such as nosocomial infection [13.6% (8/59) vs. 12.5% (6/48)], unplanned extubation [5.1% (3/59) vs. 6.2% (3/48)], falling out of bed/fall [3.4% (2/59) vs. 0% (0/48)], unexpected readmission to ICU/GICU [8.5% (5/59) vs. 10.4% (5/48)], and ICU/GICU mortality [6.8% (4/59) vs. 6.2 (3/48)] between the ICU group and GICU group (all P > 0.05). Compared with the ICU group, the incidence of PICS in GICU group was significantly lower [8.3% (4/48) vs. 25.4% (15/59), P < 0.05], the satisfaction rate of patients/families with medical care [89.6% (43/48) vs. 74.6% (44/59)] and satisfaction rate of patients/families with diagnosis and treatment environment [87.5% (42/48) vs. 67.8% (40/59)] were significantly increased (both P < 0.05). CONCLUSIONS: The use GICU as a friendly management model for elderly critically ill patients is feasible and safe, and it is worthy of further exploration and research.

Feasibility and Acceptability of Antenatal Hepatitis C Screening: A Pilot Study.

Introduction: Hepatitis C virus (HCV) is not currently included in the United Kingdom routine antenatal screening program, but the latest guidelines from the Centers for Disease Control and Prevention, American Association for the Study of Liver Diseases, and Infectious Diseases Society of America recommend HCV screening for all pregnant women during each pregnancy. The aim of this study was to collect qualitative data on the feasibility and acceptability of antenatal HCV screening in pregnant women at the time of routine antenatal screening at 12 weeks, to estimate patient knowledge about HCV and identify the prevalence of HCV infection in antenatal women. Methods: This was a pilot study targeting a single hospital-based antenatal clinic in Birmingham, initially conducted for eight weeks with a further extension of the study period to enhance recruitment to meet the feasibility target of 500 patients. Data collected included demographic and epidemiological details. Pregnant women attending the antenatal unit were given information regarding HCV and antenatal screening for HCV prior to their initial antenatal visit. During the antenatal visit, research nurses provided further information about the study and HCV infection. Consent was obtained for taking part in the study and testing for HCV using blood samples taken at the same time as other routine antenatal screening blood tests. All women who agreed to participate in the study were asked to complete an acceptability and knowledge questionnaire. All women had HCV antibody testing as the primary screening assay. The test result was communicated in writing to the women and their general practitioner. Confirmatory positive antibody tests were followed up with quantitative HCV PCR and genotype analysis. The outcomes of testing were no evidence of HCV infection and evidence of past HCV infection or current HCV infection. Results: Five hundred and forty-nine women were approached in the antenatal clinic; 30 women refused consent while 29 women were excluded from the study (blood tests not performed after consenting, age less than 18 years, and consent form lost). Four hundred and ninety women were included in the study. The median age of the study population was 29 years (range, 18-46). Knowledge about blood-borne viruses was limited; 75% of women had some understanding about antenatal hepatitis B (HBV) and human immunodeficiency virus (HIV) testing. Previous awareness about hepatitis C was reported by 55%. Ninety-one percent of women found the information they were given about hepatitis C helpful. Ninety-six percent of the women included in this study found the counselling they received about HCV useful and felt that the delivery of this information was carried out in an acceptable manner. Once given information about HCV, 99% felt that universal screening for HCV should be implemented. HCV antibody was negative in 489 women. One patient with a positive HCV antibody (prevalence: 0.2%) had a negative HCV PCR. Conclusion: Routine antenatal screening for HCV is not currently recommended in the UK. Our study suggests that antenatal HCV screening would be both feasible and acceptable to most pregnant women attending antenatal clinics. Though the awareness of HCV was low, with appropriate counselling and communication, 99% of pregnant women were in favor of antenatal screening for HCV. Antenatal screening would identify HCV-positive mothers and allow follow-up of their infants so that any infected mothers and infants could be offered effective curative therapy and prevent the progression of liver disease. The inclusion of HCV antenatal screening would complete the blood-borne virus profile and enhance the WHO target to eliminate HCV in the UK.

Untutored learning curve for endoscopic submucosal dissection in New Zealand.

INTRODUCTION: Endoscopic submucosal dissection (ESD) is a specialised endoscopic technique in the treatment of large pre-cancerous and early cancerous gastrointestinal lesions that avoids the need for surgical resections. The objective of this study was to assess the feasibility, efficacy and safety of learning ESD in an untutored approach in a prevalence-based setting within New Zealand. METHODS: Over a 4-year period, 80 ESD procedures were performed at a single tertiary centre within New Zealand. We retrospectively reviewed basic demographics of the patients, along with successful en bloc resection rates, dissection speeds, histological diagnoses (including margin assessments) and complications. RESULTS: We captured 80 procedures. Within this database we achieved an en bloc resection of 88.7% (71 out of 80 cases) and an R0 resection of 72.5% (58 out of 80 cases). The international benchmark for dissection speed of 9cm2/h was achieved within the first block of 20 cases and was maintained throughout. There was a perforation rate of 6.25% (five patients), with one patient (1.25%) requiring emergency surgery for a rectal perforation. CONCLUSIONS: Our study shows it is feasible and safe to learn ESD within a low-volume tertiary centre within New Zealand via a prevalence-based approached. The majority of patients were able to have en bloc resection and a R0 resection. Our intent is that this data be used to help design a more formalised training process for learning ESD within a New Zealand setting.

Evaluation of a digital therapy programme for the treatment of primary arterial hypertension: eXPLORE - study protocol for a fully decentralised randomised controlled feasibility study.

INTRODUCTION: Hypertension is a major cause of premature death worldwide as it is an important risk factor for coronary artery disease, myocardial infarction, heart failure and stroke. Although an estimated 1.3 billion adults suffer from hypertension, less than half of them are diagnosed correctly and therefore receive sufficient treatment. Furthermore, only one fifth of those treated reach the therapy target of normotension. This significant deficit underlines the need for new therapy concepts to improve long-term health outcomes. Several studies have shown positive effects of digital health programmes in the disease management of ambulatory, long-term hypertension treatment. More research is needed to explore the abilities of digital health programmes as an innovative pathway in ambulatory healthcare.The eXPLORE study aims to evaluate the feasibility of a clinical trial on the impact of a supplementary digital therapy programme for the treatment of primary arterial hypertension. METHODS AND ANALYSES: The eXPLORE study collects data in the setting of a prospective randomised controlled trial to evaluate methodological feasibility for larger-scaled follow-up research. The study compares a digital therapy programme using a smartphone application that is based on functions and algorithms creating tasks and recommendations based on individual health data to standard care for the treatment of primary arterial hypertension. The study period is 180 days, with a 90-day in-life phase followed by a 90-day follow-up phase. Baseline and follow-up data (3 months, 6 months follow-up) of all participants included is collected via questionnaire surveys as well as self-administered blood pressure monitoring. Patient inclusion, initial data acquisition and follow-up were carried out in an innovative remote setting. The study was initiated in November 2022 and is currently ongoing. Study outcome measures are changes in mean blood pressure, health literacy and self-sufficient health behaviour. ETHICS AND DISSEMINATION: The eXPLORE study is carried out in accordance with all applicable legal regulations. Cost-effectiveness is assured by continuous evaluation and documentation over the course of the study. All health-relevant data from the eXPLORE study will be provided for analyses and publication to the investigators of LMU Hospital. The study was approved by the local ethics committee of LMU Munich (project nr.: 22-0115). TRIAL REGISTRATION: NCT05580068. PROTOCOL VERSION: 1.5, 28.08.2023.

Investigating the impact of multidisciplinary prehabilitation on deconditioning in patients eligible for haematopoietic allogenic stem cell transplantation: protocol for a feasibility trial.

BACKGROUND: Assessing multidisciplinary prehabilitation strategies becomes crucial to pre-emptively counter the physical, psychological and social negative impacts experienced during an allogenic haematopoietic stem cell transplant (allo-HSCT) among acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) patients. Current evidence is restricted to studies during induction chemotherapy, omitting rehabilitation interventions and predominantly using exercise-only approaches without a multidisciplinary framework. The aim of this study is to investigate the feasibility, safety and preliminary efficacy of multidisciplinary prehabilitation in adults offered allo-HSCT. METHODS AND ANALYSIS: This 8-week single-group pre-post feasibility study aims to pilot a multidisciplinary prehabilitation intervention for participants undergoing allo-HSCT, with a focus on feasibility and safety. Participants, aged 18 or older, diagnosed with AML or MDS, and offered allo-HSCT, will be recruited between June 2023 and July 2024. The multidisciplinary prehabilitation intervention, conducted by the cancer allied health team at the Royal Adelaide Hospital, includes exercise physiology, physiotherapy, dietetics, social work, occupational therapy and psychology interventions. Consistent with a multidisciplinary treatment approach, each component is tailored to address different aspects of patient care, and adherence calculations will assess patient engagement and compliance. In addition, participants will continue to receive usual care from cancer allied health staff. The primary outcome of the study is to assess the feasibility of a multidisciplinary prehabilitation intervention by evaluating intervention uptake, retention, adherence, acceptability and safety. Secondary outcomes are leg strength, upper-body strength, aerobic fitness, falls risk, anthropometry, nutritional status, quality of life, anxiety, depression, self-efficacy for coping with cancer and distress. ETHICS AND DISSEMINATION: Ethics approval for this study has been provided by the Central Adelaide Local Health Network (HREC 2022/HRE00284). Recruitment for the study commenced in June 2023 and will continue until July 2024. The methods have been designed and are reported according to the SPIRIT and CONSORT-pilot study checklist.

Exploring the feasibility and acceptability of community paramedicine programs in achieving vaccination equity: a qualitative study.

BACKGROUND: Mobile Integrated Health-Community Paramedicine (MIH-CP) is a novel approach that may reduce the rural-urban disparity in vaccination uptake in the United States. MIH-CP providers, as physician extenders, offer clinical follow-up and wrap-around services in homes and communities, uniquely positioning them as trusted messengers and vaccine providers. This study explores stakeholder perspectives on feasibility and acceptability of community paramedicine vaccination programs. METHODS: We conducted semi-structured qualitative interviews with leaders of paramedicine agencies with MIH-CP, without MIH-CP, and state/regional leaders in Indiana. Interviews were audio recorded, transcribed verbatim, and analyzed using content analysis. RESULTS: We interviewed 24 individuals who represented EMS organizations with MIH-CP programs (MIH-CP; n = 10), EMS organizations without MIH-CP programs (non-MIH-CP; n = 9), and state/regional administrators (SRA; n = 5). Overall, the sample included professionals with an average of 19.6 years in the field (range: 1-42 years). Approximately 75% (n = 14) were male, and all identified as non-Hispanic white. MIH-CPs reported they initiated a vaccine program to reach underserved areas, operating as a health department extension. Some MIH-CPs integrated existing services, such as food banks, with vaccine clinics, while other MIH-CPs focused on providing vaccinations as standalone initiatives. Key barriers to vaccination program initiation included funding and vaccinations being a low priority for MIH-CP programs. However, participants reported support for vaccine programs, particularly as they provided an opportunity to alleviate health disparities and improve community health. MIH-CPs reported low vaccine hesitancy in the community when community paramedics administered vaccines. Non-CP agencies expressed interest in launching vaccine programs if there is clear guidance, sustainable funding, and adequate personnel. CONCLUSIONS: Our study provides important context on the feasibility and acceptability of implementing an MIH-CP program. Findings offer valuable insights into reducing health disparities seen in vaccine uptake through community paramedics, a novel and innovative approach to reduce health disparities in rural communities.

Comparing 3D imaging devices for the measurement of cutaneous neurofibromas in patients with Neurofibromatosis Type 1.

BACKGROUND: Cutaneous neurofibromas (cNFs) are a major cause of disfigurement in patients with Neurofibromatosis Type 1 (NF1). However, clinical trials investigating cNF treatments lack standardised outcome measures to objectively evaluate changes in cNF size and appearance. 3D imaging has been proposed as an objective standardised outcome measure however various systems exist with different features that affect useability in clinical settings. The aim of this study was to compare the accuracy, precision, feasibility, reliability and accessibility of three imaging systems. MATERIALS AND METHODS: We compared the Vectra-H1, LifeViz-Micro and Cherry-Imaging systems. A total of 58 cNFs from 13 participants with NF1 were selected for imaging and analysis. The primary endpoint was accuracy as measured by comparison of measurements between imaging systems. Secondary endpoints included reliability between two operators, precision as measured with the average coefficient of variation, feasibility as determined by time to capture and analyse an image and accessibility as determined by cost. RESULTS: There was no significant difference in accuracy between the three devices for length or surface area measurements (p > 0.05), and reliability and precision were similar. Volume measurements demonstrated the most variability compared to other measurements; LifeViz-Micro demonstrated the least measurement variability for surface area and image capture and analysis were fastest with LifeViz-Micro. LifeViz-Micro was better for imaging smaller number of cNFs (1-3), Vectra-H1 better for larger areas and Cherry for uneven surfaces. CONCLUSIONS: All systems demonstrated excellent reliability but possess distinct advantages and limitations. Surface area is the most consistent and reliable parameter for measuring cNF size in clinical trials.

Eye-Rubbing Detection Using a Smartwatch: A Feasibility Study Demonstrated High Accuracy With Machine Learning.

Purpose: In this work, we present a new machine learning method based on the transformer neural network to detect eye rubbing using a smartwatch in a real-life setting. In ophthalmology, the accurate detection and prevention of eye rubbing could reduce incidence and progression of ectasic disorders, such as keratoconus, and to prevent blindness. Methods: Our approach leverages the state-of-the-art capabilities of the transformer network, widely recognized for its success in the field of natural language processing (NLP). We evaluate our method against several baselines using a newly collected dataset, which consist of data from smartwatch sensors associated with various hand-face interactions. Results: The current algorithm achieves an eye-rubbing detection accuracy greater than 80% with minimal (20 minutes) and up to 97% with moderate (3 hours) user-specific fine-tuning. Conclusions: This research contributes to advancing eye-rubbing detection and establishes the groundwork for further studies in hand-face interactions monitoring using smartwatches. Translational Relevance: This experiment is a proof-of-concept that eye-rubbing detection is effectively detectable and distinguishable from other similar hand gestures, solely through a wrist-worn device and could lead to further studies and patient education in keratoconus management.

Place of telemedicine in the organization of emergency care: feasibility and benefits.

INTRODUCTION: Telemedicine encompasses all medical practices that allow patients to be remotely cared for through new information and communication technologies. This study aims to assess the remote management of patients consulting emergency services and not requiring in-hospital care during both pre-pandemic and pandemic periods of COVID-19. METHODS: This was a prospective, randomized, controlled study. The telemedicine group received follow-up at home after emergency room discharge according to a predefined protocol, with telephone calls on days 2, 7, 15, and 30. The control group received standard care without regular telephone follow-up (only a call on day 30). The study was conducted with patients consulting the emergency department of FarhatHached Hospital in Sousse. Patient inclusion occurred between November 1, 2019, and April 30, 2020. The primary outcome measures were the re-consultation rate and treatment adherence. The secondary outcome measure was patient satisfaction.SPSS version 23.0 for Windows was used for data analysis. Descriptive statistics calculated frequencies, percentages, means, standard deviations, medians, and range. Analytical study involved Student's t-test and Pearson chi-square test for mean and frequency comparisons, respectively. Significance threshold (p) for all tests was set at 0.05. RESULTS: A total of 400 patients were included. The average age of patients was 40 years. Both groups were comparable in terms of demographics and clinical characteristics. Diagnoses included mainly benign infectious diseases, trauma, mild decompensations of chronic conditions (asthma, COPD, heart failure), and suspected COVID cases. Patients in the telemedicine group tended to reconsult less in the month following their initial emergency room visit (14% versus 26.5%) (p = 0.004). There was a significant difference in treatment adherence between the telemedicine group and the control group (97.5% versus 92%; p = 0.014). The satisfaction with telemedicine was higher than satisfaction with regard to an in-person consultation at the emergency department (90% versus 37.5%). CONCLUSION: It is necessary to implement telemedicine in Tunisia, especially in emergency services. It ensures better remote patient care by reducing re-consultation rates, increasing treatment adherence, and improving patient satisfaction.

Reduced port laparoscopic rectopexy for full-thickness rectal prolapse.

BACKGROUND: Laparoscopic rectopexy is an established treatment option for full-thickness rectal prolapse. Recently, reduced port surgery (RPS) has emerged as a novel concept, offering reduced postoperative pain and improved cosmetic outcomes compared with conventional multiport surgery (MPS). This study aimed to evaluate the feasibility and safety of RPS for full-thickness rectal prolapse. METHODS: From October 2012 to December 2018, 37 patients (MPS: 10 cases, RPS: 27 cases) underwent laparoscopic rectopexy for full-thickness rectal prolapse. Laparoscopic posterior mesh rectopexy (Wells procedure) is the standard technique for full-thickness rectal prolapse at our hospital. RPS was performed using a multi-channel access device, with an additional 12-mm right-hand port. Short-term outcomes were retrospectively compared between MPS and RPS. RESULTS: No significant differences were observed between MPS and RPS in the median operative time, the median blood loss volume, the postoperative complication rates, and median hospital stay duration after surgery. CONCLUSION: Reduced port laparoscopic posterior mesh rectopexy may serve as an effective therapeutic option for full-thickness rectal prolapse. However, to establish the superiority of RPS over MPS, a prospective, randomized, controlled trial is warranted.
