Manual wheelchair training approaches and intended training outcomes for adults who are new to wheelchair use: A scoping review.

Wheelchair training is pivotal for safety, independence, and occupational engagement in the community, yet adults coming into wheelchair use often receive insufficient or untailored training. This research aimed to understand the range and type of manual wheelchair training approaches that exist for adults commencing wheelchair use. A systematic scoping review involved searching eight electronic databases and grey literature up to September 2023. Papers relating to manual wheelchair training for adults and their caregivers were included for data extraction. Eighty-seven articles were included in this review. The International Classification of Functioning (ICF) was used to organise and analyse data related to intended training outcomes. Consumer consultation was not included in this review; however, the outcomes suggest that involving consumers in future wheelchair training research is critical to assure community participation outcomes. Data were extracted from 87 papers. Manual wheelchair training was delivered across diverse contexts encompassing varied support structures, trainer backgrounds, and technology and was commonly directed towards wheelchair users with spinal cord injury. Intended training outcomes most frequently mapped to the activity and participation component of the ICF (n= 39), followed by personal factors (n= 27), body structures and functions (n= 18), and environmental factors (n= 3), with limited focus on longer term occupational engagement outcomes. Most existing manual wheelchair training focussed on the acquisition of individual wheelchair skill and may not facilitate generalised and long-term occupational participation outcomes. Further exploration into the contexts that support occupational engagement, particularly for older adults with progressive conditions, is required to support service provision. We looked at what manual wheelchair training approaches exist for adults who need to use a manual wheelchair and what training helps people to do/achieve. We did a scoping review that looked at literature about manual wheelchair training programs for adult wheelchair users. We found 87 research papers and training programs that we included in our review. We recorded and analysed information from all the papers about the wheelchair training programs and outcomes for people who do these programs. We found that manual wheelchair training can be done in structured or ad hoc ways, can have different amounts of training, can be provided face-to-face or online, and can be given by different allied health professionals and other wheelchair users. Most training programs had short-term outcomes like learning manual wheelchair skills, being able to use the wheelchair properly, and feeling confident about using a wheelchair. Some had longer term outcomes about being able to use the manual wheelchair in everyday activities. Most people who did the training programs that we looked at in this review were manual wheelchair users with spinal cord injury. Because not many wheelchair programs have been tried with people who do not have a spinal cord injury, it is hard for occupational therapists to make recommendations about training for other people who use a manual wheelchair. Manual wheelchair training that is done in the community and made to meet the needs of individuals may help people with using their wheelchair for their everyday activities and participate in their community.

Retail company voluntary arrangements: A dubious remedy?

AbstractDespite much debate on Company Voluntary Arrangements (CVA) among UK retailers, understanding of retail CVAs remains limited. There is continuing uncertainty about the uptake of CVAs, what aspects lead to successful outcomes and whether CVAs can be viewed as a remedy for struggling UK retailers. To address these questions, we developed and analysed a novel and detailed dataset of Companies House records for the population of retailers' CVAs between mid‐2012 and early 2021. We find that CVAs, despite detrimental impacts on other actors (landlords and suppliers), can be a useful tool for some retailers in adjusting to the new market conditions. The uptake of CVAs among retailers is stable, though not among large retailers. Retail CVAs help to avoid immediate business failure, but we found limited evidence of the success and efficient longer term outcome of the procedure, suggesting that alternative methods could be considered. The success and efficiency of CVA do not seem to depend on the size of the business, but there are variations in both the uptake and efficiency of CVAs across retail sub‐sectors. This suggests that a range of mechanisms are required to cater to the different needs across retail categories. Despite the market challenges, CVAs are not prolonged on average. However, longer duration CVAs seem to have a lower chance of succeeding and of being efficient implying that CVA cannot remedy fundamental business issues. Finally, we observed differences related to who oversees the procedure, suggesting that greater emphasis should be put on upskilling and selection of insolvency practitioners.

Outcomes after endovascular revascularization for chronic limb-threatening ischemia from the only Vascular Quality Initiative (VQI) center in Asia

ObjectiveThis study compares chronic limb-threatening ischemia disease characteristics and endovascular revascularization outcomes in a multi-ethnic Asian cohort vs their North American counterparts. MethodsThe Society for Vascular Surgery Vascular Quality Initiative (VQI) registry database from the first and currently the only VQI center in Asia was reviewed to identify patients with chronic limb-threatening ischemia who underwent endovascular revascularization between July 2019 and April 2024. Standardized VQI reporting variables were compared against benchmarks derived from all participating centers in North America. ResultsA total of 2862 endovascular revascularization procedures from our center were benchmarked against 129,347 procedures from 406 North American centers. Our cohort had a higher burden of comorbidities (diabetes mellitus, end-stage renal disease, cardiac disease) and presented with more advanced Wound, Ischemia, and foot Infection stages. Our patients had more heavily calcified and longer (14.8 cm vs 6.0 cm) diseased vessels with higher prevalence of multi-level (87% vs 54.6%), infrapopliteal (52.6% vs 38.9%), and inframalleolar (9.6% vs 2.4%) disease. Rates of technical success (92.7% vs 93%) and symptom improvement (39.1% vs 40.4%) were comparable between cohorts. However, 1-year mortality rates (28.9% vs 25.1%) and major amputation rates (13.3% vs 7.8%) were significantly higher. ConclusionsShort-term outcomes of technical success and symptom relief in our center were comparable to benchmarked North American outcomes despite having a cohort with more diseased vessels, higher Wound, Ischemia, and foot Infection stages, and more comorbidities. However, this cohort fared worse in longer term outcomes of 1-year mortality and major amputation rates. Further studies are required to elucidate the causes to improve these outcomes.

Long term outcome of IgE-mediated cow's milk allergy and risk factors for persistence

Resolution rates of IgE-mediated cow's milk allergy (IgE-CMA) by age 5 years, and risk factors for its persistence were previously described. To extend follow-up until the end of adolescence. An extension study of 23 of 54 patients diagnosed with IgE-CMA from a population-based study of 13,019 newborns, who remained allergic at age 5 years. Patients were examined at age 17 and their history reviewed. Resolution was determined by regular milk consumption without adverse reactions, or a negative oral food challenge (OFC). Allergy was defined by a recent objective reaction to milk and a positive skin prick test (SPT), or by sensitization ≥95% PPV to milk. Risk factors for persistence at age 17 were examined in the entire cohort. Of the 23 patients followed, 8/23 (35%) had spontaneous resolution, and 15 had persistent IgE-CMA. Overall, 39 (72.2%) of the 54 patients initially diagnosed with IgE-CMA had spontaneous resolution by age 17. Risk factors for IgE-CMA persistence at age 17 years included SPT >6 mm at time of diagnosis (p=0.03), no cow's milk formula feeding in the nursery (p=0.008), and wheezing on diagnostic OFC/initial reaction to milk (p=0.04). Seven patients experienced objective reactions after age 5 years. These patients had more wheezing (p=0.045) or anaphylaxis (p=0.02) on diagnostic OFC/initial reaction and more current asthma (p=0.007). Significant rate of spontaneous resolution of IgE-CMA still occurs beyond age 5 and few patients with IgE-CMA, mostly asthmatics, experience objective reactions by early adulthood. This should be considered in the treatment approach of IgE-CMA patients.

Single institution review of operative management of giant omphalocele

PurposeOperative management of giant omphalocele that cannot be closed primarily varies based on several factors, and there is little data to guide choice of operative approach and how this impacts long-term outcomes. We aimed to characterize whether surgical approach – staged closure during the neonatal period, or delayed closure – affects outcomes. MethodsWe conducted a retrospective review of children treated for giant omphalocele who did not undergo primary closure at Children's Hospital Colorado from 2010–2022. We included patients with giant omphalocele who underwent treatment at the study site. Data collected included patient characteristics, clinical course, and outcomes. Comparisons were made based on type of closure, delayed versus staged. ResultsWe identified 24 patients; 6 delayed and 16 staged. 2 patients died prior to closure. Delayed and staged groups did not differ regarding demographics. Infants undergoing staged repair tended to have more total hospital and total ventilator days, and more post-closure ventral hernia requiring repair; short-term outcomes were otherwise comparable. There was no difference between groups in long-term outcomes, including neurodevelopmental milestones and mortality. ConclusionsLong term outcomes are equivalent between staged repair and delayed repair of giant omphalocele. However, staged repair may be associated with more ventilator days, total hospital days and higher risk of ventral hernia.

Outcomes and Complications of Image-Guided Percutaneous Tumour Ablation for Hepatocellular Carcinoma at the Irish National Liver Transplant Centre.

Background: Image-guided tumour ablation is a minimally invasive treatment for early stage hepatocellular carcinoma (HCC). Our study reviews the complications and long term outcomes in patients treated at a tertiary referral centre. Methods: Retrospective study. All patients with HCC who underwent microwave ablation (MWA) or radiofrequency ablation (RFA) from 1st January 2014 to 31st December 2022 were identified. Treatment response of target lesion, complications, and survival were recorded. Results: One hundred seventy ablations were performed in 118 patients; 70% MWA, 30% RFA. Median radiological follow-up 21 months (range 3-107). Follow-up imaging was reported using LI-RADS and mRECIST. At first follow-up imaging, 94 patients had complete response (primary efficacy rate 80.3%) while 19.7% (n = 23) had residual disease. Fifteen of these had repeat ablation; 10 had complete response (secondary efficacy rate 85.6%). By end of study duration, 70.5% (n = 79) achieved sustained local complete response from single ablation without documented recurrence. 14.3% (n = 16) required more than one ablation of target lesion. Overall, 84.8% (n = 95) demonstrated long term local complete response to ablation. Complication occurred in 5.9% (n = 10); 40.0% Grade I, 40.0% Grade II, 10.0% Grade III, 10.0% Grade IV as per the CIRSE Classification. 1-, 3-, and 5-year overall survival (OS) rate was 97%, 68%, and 61% respectively. Mean OS was 5.3 years (median 4.7). No difference in OS (P = .7) or local progression free survival (P = .5) between patients treated with MWA versus RFA. Conclusion: This study demonstrates excellent long-term response to TA, with acceptable complication profile. No difference in survival between RFA versus MWA.

18F-FDG PET/CT biomarkers as predictors of long term outcomes and survival rates in patients with high risk malignant pulmonary masses/nodules treated with stereotactic ablative radiotherapy.

Stereotactic ablative body radiotherapy (SABR) is a standard treatment option for patients with malignant pulmonary masses (including primary and metastatic lesions) who are unfit for surgery or who are medically operable but refuse surgery. Flourine-18 flurodeoxyglucose positron emission tomography (18F-FDG PET) volumetric metabolic parameters, i.e., metabolic tumour volume (MTV) and total lesion glycolysis (TLG) play an important role in assessing the biological characteristics of some tumours and its role as potential prognostic factors has also been introduced. The aim of this retrospective study is to assess the value of baseline metabolic volumetric parameters as prognostic imaging biomarkers in patients with pulmonary masses/nodules treated with SABR. 70 patients were included in this retrospective study (39 male and 31 female, age range 47-91years, mean 76years). Standardized uptake value (SUVmax), SUVmean, MTV and TLG for all the patients were calculated on baseline 18F-FDG PET/CT. Patient outcome was divided into 3 categories free of disease, stable disease and disease progression. There was no significant statistical difference in the SUVmax and SUVmean in all the three categories. Mean SUVmax ranges from 7.13 to 8.08 with its highest value in the stable disease and lowest value in the progressive disease categories. Similarly, the average SUVmean was 4.9 in the free of disease category and 4.68 in the progressive disease category. MTV and TLG were low in the free of disease and the highest in progressive disease. MTV increased from 2.25 cm3 in free of disease category to 3.23 cm3 and 7.29 cm3 in stable disease and progressive disease, respectively. TLG has increased from 11.7 in the disease-free survival category to 18.77 and 40.39 in the stable and progressive disease, respectively. Patients with low MTV had longer overall survival (OS) than patients with high MTV (37months versus 27months, p value = 0. 0018). In addition, OS was longer in patients with low TLG (36months versus 24months, p value = 0.016). TLG and MTV are more useful than SUVmax and SUVmean for predicting outcome, OS and progression-free survival (PFS) in patients receiving SABR. The TLG and MTV measurement on 18F-FDG PET imaging may be routinely recommended in baseline 18F-FDG PET/CT prior to SABR.

Bridging the gap — Establishing a dental-oncology service in a cancer centre

Dental disease remains the most common non-communicable disease worldwide. It predisposes patients to significant morbidities following bone modifying agents or radiation therapy to the head and neck. Preventative dental regimes effectively reduce the risk of both medication-related osteonecrosis of the jaw (MRONJ) and osteoradionecrosis (ORN) in these patients. Co-ordination of routine dental care as a component of mainstream oncology treatment optimises long term outcomes for oncology patients. This case series offers insights into patient, institutional and social difficulties that challenge the dental-oncology interface. These obstacles and subsequent resolutions experienced whilst establishing a dental-oncology service in a cancer centre highlight the importance of effective multidisciplinary lead care for oncology patients. It reinforces the need for structured, supported dental pathways for these oncology patients.

Long term outcomes in patients with advanced intrahepatic cholangiocarcinoma treated with hepatic arterial infusion chemotherapy.

Hepatic artery infusion (HAI) of chemotherapy has demonstrated disease control and suggested improvement in overall survival (OS) in intrahepatic cholangiocarcinoma (IHC). We report herein the long-term results and role of molecular alterations of a phase II clinical trial of HAI chemotherapy plus systemic chemotherapy, with a retrospective cohort of patients treated with HAI at Memorial Sloan Kettering Cancer Center. This secondary analysis of a single-institution, phase 2 trial and retrospective cohort of unresectable IHC treated with HAI floxuridine (FUDR) plus systemic gemcitabine and oxaliplatin. The primary aim was to assess long-term oncologic outcomes. A subset underwent tissue-based genomic sequencing, and molecular alterations were correlated with progression-free survival (PFS) and OS. Thirty-eight patients were treated on trial with a median follow up of 76.9 months. Median PFS was 11.8 months (95% CI11-15.1). The median OS was 26.8 months (95% CI20.9-40.6). The 1-, 2- and 5-year OS rate was 89.5%, 55%, and 21% respectively. Nine (24%) received HAI with mitomycin C post FUDR progression with an objective response rate of 44% and a median PFS of 3.93 (2.33-NR) months. One-hundred and seventy patients not treated on the clinical trial were included in a retrospective analysis. Median PFS and OS was 7.93 (95%CI: 7.27-10.07) and 22.5 (95%CI : 19.5-28.3) months, respectively. Alterations in the TP53 and cell-cycle pathway had a worse PFS to HAI based therapy compared to wildtype disease. In locally advanced IHC, HAI with FUDR in combination with systemic therapy can offer long term durable disease control. Molecular alterations may predict for response.

Short- and long- term outcomes of mechanical thrombectomy in acute ischemic stroke patients with chronic kidney disease.

Chronic kidney disease (CKD) is a risk factor of acute ischemic stroke (AIS). Outcomes of treatment with mechanical thrombectomy (MT) in patients with CKD seem to be poorer than in the general population. Long‑term follow‑up studies are lacking. Our aim was to asses short- and long‑term outcomes (up to 365 days after stroke) in MT‑treated AIS patients with concomitant CKD. The study included all AIS patients treated with MT at the Comprehensive Stroke Center in Kraków, Poland, from 2019 to 2021. The patients were divided into the CKD group (best glomerular filtration rate [GFR] during hospitalization <60 ml/min/1.73 m2 or diagnosed CKD) and the controls. In‑hospital, 90‑day, and 365‑day mortality and rate of good functional outcomes (defined as modified Rankin Scale ≤2) were compared between the CKD patients and controls as well as between patients with CKD stages 1-3 (GFR ≥30 ml/min/1.73 m2) and 4-5 (GFR <30 ml/min/1.73 m2). Factors associated with the abovementioned outcomes were identified using univariable logistic regression analyses and then added to multivariable analyses. The CKD patients had higher 90- and 365‑day mortality and lower 90- and 365‑day good functional outcome rates than the controls. The patients with CKD stage 4-5 had significantly higher in‑hospital, 90‑day, and 365‑day mortality than the patients with CKD stage 1-3. Neither CKD nor its late stages (4-5) were independently associated with short- and long‑term mortality and functional outcomes of MT. MT outcomes in CKD patients are worse, especially in advanced stages of the disease, but CKD is not independently associated with poor prognosis. CKD alone should not be a contraindication for MT in otherwise eligible patients, although patients with impaired kidney function require more careful postprocedural monitoring.

The evolution of evidence-based methods of acute myocardial infarction treatment: is there any reason for optimism in recent years?

The article briefly describes the stages of creating the main methods of acute myocardial infarction (MI) and its complications treatment. It is noted that currently existing clinical guidelines (CG) were formed at the end of the first decade of the XXI century; since then there have been no principal changes in the CG due to the lack of fundamentally new approaches to the acute MI treatment, its immediate and long-term outcomes. Compliance with the current CG has significantly reduced hospital mortality in acute MI and improved long-term outcomes. However, today, despite compliance with the CG, the absolute hospital mortality rates for acute MI remain quite high, and the long-term prognosis of patients’ lives is very unfavorable. A number of major randomized clinical trials that ended in 2023-2024 and studied fundamentally new approaches to the treatment of acute MI and its long–term outcomes are analyzed. It is noted that none of these studies gave a positive result. A new study with beta-blockers, which proved its positive effect on the mortality of patients with acute MI in the 80s of the twentieth century, gave negative results. This may indicate that a number of acute MI treatment methods, the effectiveness of which was proven several decades ago, have now lost their significance. It is concluded that despite compliance with modern CG, the residual risk of death after acute MI remains quite high. It is necessary to develop principally new methods of treating this disease.

Short Term Outcomes of a Prospective Registry in Popliteal and Infrapopliteal Endovascular Interventions for Chronic Limb Threatening Ischaemia

The prevalence of chronic limb threatening ischaemia (CLTI) is increasing worldwide, resulting in the need for more patients undergoing revascularisation, especially for below the knee pathology. Nevertheless, prospective data on below the knee endovascular interventions are lacking. The aim of the study was to provide large scale, real world data on procedural and short term outcomes of popliteal and infrapopliteal endovascular interventions in patients with CLTI. This study is an analysis of the first 1 000 interventions of the Dutch Chronic Lower Limb-Threatening Ischemia Registry (THRILLER). It includes all patients with CLTI undergoing popliteal or infrapopliteal endovascular revascularisation in seven hospitals in the Netherlands. The primary outcomes were limb salvage and amputation free survival (AFS) at three months estimated with the Kaplan-Meier method. Secondary outcomes were procedural complications and primary patency. Between February 2021 and July 2023, 1 000 endovascular procedures were performed in 840 patients (947 limbs), treating 486 popliteal and 1 209 tibial lesions. Wound, Ischemia, and foot Infection (WIfI) stages 1 - 4 were present in 16.8%, 17.2%, 25.4%, and 40.6% of the limbs, respectively. Technical success was hampered by arterial perforation, acute thrombosis, and distal embolisation in 8.7%, 1.0%, and 2.3% of the interventions, respectively. Limb salvage was 100.0%, 96.9%, 94.9%, and 86.1% (p < .001), whereas AFS was 96.9%, 93.2%, 86.6%, and 76.4% for WIfI stages 1 - 4 at three months (p < .001), respectively. Primary patency at the 6 - 8 week visit was 86.4% for popliteal and 74.3% for tibial lesions, respectively. THRILLER presents a large prospective database on outcomes of CLTI endovascular interventions. Popliteal and infrapopliteal endovascular revascularisation for CLTI is safe. Interventions with initial technical success have high rates of limb salvage and survival at three months. The WIfI classification provides a reliable instrument to predict limb salvage and AFS independently at three months.

Prevention and Reduction of Anxiety in Autistic Preschoolers Through an Autism-Specific Parent-Mediated Intervention: A Pilot Randomised Controlled Trial Evaluating Short and Longer Term Outcomes.

Anxiety is a common co-occurring condition for autistic preschoolers. Whilst there has been extensive research evaluating anxiety prevention/reduction interventions for neurotypical preschoolers, such research is limited for autistic children. Fifty-seven parents of autistic 4-5-year olds, with varying levels of anxiety, participated in a randomised controlled trial of an autism-specific, parent-mediated intervention (CLK-CUES) to prevent or reduce anxiety in autistic preschoolers. Baseline, short-term (post-intervention) and longer term (12 months follow-up) assessments included child anxiety (ASC-ASD-P and PAS-R), intolerance of uncertainty, and parent well-being. (Trial registration ACTRN12620001322921). There were no reports of harmful effects of the intervention or trial. Linear mixed models show a significant group x time interaction for ASC-ASD-P Total score and the Uncertainty subscale with medium and large effect sizes. Post-hoc analyses show a significant decline for only the intervention group in anxiety (specifically, anxiety around uncertainty) from pre-post intervention, maintained at one year follow-up. There was no change on the PAS-R or other ASC-ASD-P subscales. CLK-CUES shows promise as a way to prevent and reduce anxiety in young autistic children, specifically anxiety related to uncertainty. Trials with larger samples are warranted. Findings also highlight the importance of using measures designed for autistic children.

Sleep state-dependent development of resting state functional connectivity during the preterm period.

The brains of preterm infants exhibit altered functional connectivity (FC) networks, but the potential variation in sleep states and the impact of breathing patterns on FC networks are unclear. This study explores the evolution of resting-state FC from preterm to term, focusing on breathing patterns and distinguishing between active sleep and quiet sleep. We recruited 63 preterm infants and 44 healthy-term infants and performed simultaneous electroencephalography and functional near-infrared spectroscopy. FC was calculated using oxy- and deoxyhemoglobin signals across eight channels. First, FC was compared between periodic breathing (PB) and non-PB segments. Then sleep state-dependent FC development was explored. FC was compared between active sleep and quiet sleep segments and between preterm infants at term and term-born infants in each sleep state. Finally, associations between FC at term, clinical characteristics, and neurodevelopmental outcomes in late infancy were assessed in preterm infants. In total, 148 records from preterm infants and 44 from term-born infants were analyzed. PB inflated FC values. After excluding PB segments, FC was found to be elevated during active sleep compared to quiet sleep, particularly in connections involving occipital regions. Preterm infants had significantly higher FC in both sleep states compared to term-born infants. Furthermore, stronger FC in specific connections during active sleep at term was associated with unfavorable neurodevelopment in preterm infants. Sleep states play a critical role in FC development and preterm infants show observable changes in FC.
