Published: August 2024

This study develops an impermeable and flexible sheet for food packaging using aluminium foil and jute web. A hot melt sheet is used for laminating foil with a jute web. A simple manufacturing process has been suggested. The effect of different process parameters has been studied and optimized. The optimized calendaring temperature (top/bottom), pressure, and speed are 150/120°C, 15 kPa, and 1 m/min, respectively. Preheating and three consecutive runs show higher tenacity. This hybrid sheet uses around 88% or 78% jute (by weight) in one and both side laminated sheets, respectively. The failure mechanism shows the role of fibre-to-foil bonding. The developed fabric is lighter and more cost-effective than jute woven laminated fabric. The packet from hybrid fabric is sufficiently strong and pliable with excellent barrier properties to use as a hygienic sheet for food packaging.

Published: August 2024

In order to address the problem of transition slip between the cylindrical segment and the ellipsoidal head segment of the carbon/carbon composite crucible preform with asymmetrical structure during the winding process, a winding pattern combining geodesic and non-geodesic is presented innovatively. Firstly, the formulae for the winding angle and the winding central rotation angle of the crucible cylindrical segment and the ellipsoidal head segment are established, and the fourth-order Runge-Kutta numerical method is employed for parametrical design. The two-tangent point winding path is determined by analyzing the effect of the cylindrical segment’s winding pitch, different ellipsoidal head segment heights, and slip coefficient on the winding angle. Secondly, the needle disk winding method is proposed to address the slight winding angle at the open end of the cylinder, making it easier to hang the yarn. Finally, the experiment on dry yarn winding of 3k carbon fiber (linear density: 198 g/km) is carried out. The results indicate that the relative error rate between the actual winding angle and the theoretical design angle differs by no more than 1.66%, demonstrating that carbon fibers can be stably and uniformly wound onto the surface of the carbon/carbon composite crucible preform. Compared to the traditional manual winding method, the winding pattern enhances winding efficiency, ensures carbon fibers’ uniformity and structural stability, and provides a new technological approach to producing high-performance composite materials.

Background Deep venous outflow (VO) may be an important surrogate marker of collateral blood flow in acute ischemic stroke patients with a large vessel occlusion (AIS-LVO). Researchers have yet to determine the relationship between deep VO status in late-window patients and imaging measures of collaterals, which are key in preserving tissue. Materials and Methods We performed a multicenter retrospective cohort study on a subset of DEFUSE 3 patients recruited across 38 centers between May 2016 and May 2017 who underwent successful thrombectomy revascularization. Internal cerebral vein opacification was scored on a scale of 0–2. This metric was added to the cortical vein opacification score to derive the comprehensive VO (CVO) score from 0 to 8. Patients were stratified by favorable (ICV+) and unfavorable (ICV−) ICV scores, and similarly CVO+ and CVO−. Analyses comparing outcomes were primarily conducted by Mann–Whitney U and χ2 tests. Results Forty-five patients from DEFUSE 3 were scored and dichotomized into CVO+, CVO−, ICV+, and ICV− categories, with comparable demographics. Hypoperfusion intensity ratio, a marker of tissue level collaterals, was significantly worse in the ICV− and CVO− groups (p = 0.005). ICV− alone was also associated with a larger perfusion lesion (138 ml vs 87 ml; p = 0.023). No significant differences were noted in functional and safety outcomes. Conclusions Impaired deep venous drainage alone may be a marker of poor tissue level collaterals and a greater degree of affected tissue in AIS-LVO patients presenting in the late-window who subsequently undergo successful revascularization.

Purpose: The British Orthopaedic Association Standards for Trauma-4 includes pediatric Gustilo–Anderson type I upper limb open fractures and recommends surgical debridement as the preferred method of treatment. The reported incidence of fracture-related infection is low in patients with this injury pattern and the evidence supporting debridement is therefore weak. The aim of this systematic review is to compare infection rates between non-operative management and operative debridement in children with Gustilo I upper limb fractures who did not require surgical fixation. Methods: A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eligibility criteria included patients <18 years with Gustilo–Anderson type I upper limb fractures managed with either antibiotics alone or with operative debridement. Patients in whom the fracture was stabilized were excluded, and the Risk Of Bias In Non-randomized Studies—of Interventions tool was used to evaluate bias. Results: Eleven, predominantly retrospective studies were identified, involving 537 patients with fractures including 466 forearm, 70 wrist, and one humerus. A non-operative management strategy was used in 293 patients with one superficial infection (0.3%). Operative debridement was used in 244 patients with one superficial infection (0.4%). Conclusion: The optimal management of Gustilo–Anderson type I pediatric upper limb fractures is unclear. Based on the current evidence base, surgical debridement does not appear to reduce the rate of infection. The decision to manage these injuries aggressively should therefore be individualized to consider patient age, mechanism, and clinical extent of injury. Level of evidence: level II.

Published: August 2024

Objective As the world faces an aging population, the complexities of care management become increasingly pronounced. While technological solutions hold promise in addressing the dynamic demands of care, many nuances are to be considered in the design and implementation of active and assisted living technologies (AAL) for older adult care. This qualitative study, set in southern Spain, is positioned at the crossroads of healthcare challenges, as seen by the different actors involved in the care process and the technological solutions developed in response to these challenges. By investigating the complex landscape of caregiving and by examining the experiences and challenges faced by caregivers, healthcare professionals, and older adults, we aim to guide the development of vision-based AAL technologies that are responsive to the genuine needs of older adults and those requiring care. Methods A qualitative research methodology was used in the study. In total15 in-depth interviews and five focus groups were conducted with a diverse group of stakeholders involved in the process of care provision and reception. Results While the results demonstrate that there is a readiness for technological solutions, concerns over privacy and trust highlight the need for a carefully integrated, human-centric approach to technology in caregiving. Conclusion This research serves as a compass, guiding future discussions on the intersection of aging, technology, and care, with the ultimate goal of transforming caregiving into a collaborative and enriching journey for all stakeholders involved.

Introduction An estimated one billion people globally are currently suffering from hypertension. Prevention and management of hypertension are suboptimal especially in low- and middle-income countries leading to increased complications and deaths. With increased mobile phone coverage globally, this study aims to review mobile health technologies used for the prevention and management of hypertension. Methods We conducted a literature search on electronic databases using identified keywords involving “hypertension”, “mobile health technology” and their synonyms. Snowballing technique was also used. Papers were screened at two levels by independent reviewers. The targets were studies published in peer-reviewed journals reporting mobile health interventions for hypertension prevention and management. Only primary research studies published in English from January 2017 to April 2024 were included. Google Forms were used to extract the data along with other characteristics, and selected articles were categorised into: mobile application, web-based solutions, and Short Message Service (SMS) and other offline solutions. Result The search yielded 184 articles, and 44 studies were included in the review. Most (n = 26) were randomised control trials. Twenty-two studies (22) focused only on mobile applications solutions, 12 on SMS and other offline mHealth, 5 web-based solutions, and 5 combined more than one type of mobile health technology. The United States of America had the majority of studies (n = 17), with 6 studies from other American countries, 11 from Asia and nine from Europe, while only one from Africa. A total of 36 studies reported that mobile health technology significantly improved hypertension care through reduced blood pressure, improved adherence to follow-up visits and medications, and lifestyle changes. SMS and offline mHealth strategies have also demonstrated effectiveness in promoting self-management and reducing racial disparities in hypertension care. Conclusion Mobile health technology has the potential to play a significant role in the prevention and management of hypertension. However, there is a need for mobile health solutions for hypertension prevention and management in African countries and other developing countries. Integrating mHealth into primary healthcare delivery would also go a long way in strengthening patient care and reducing the burden on healthcare systems.
Monitoring muscle activity in pediatric SCI: Insights from sensorized rocking chairs and machine-learning
Authors: George Johnathan J , Behrman Andrea L , Roussel Thomas J 
Published: August 2024

Introduction: Activity-based therapy is effective at improving trunk control in children with spinal cord injury. A prototype sensorized rocking chair was developed and confirmed as an activity that activates trunk muscles. This study uses data collected from the chair to predict muscle use during rocking. Methods: The prototype rocking chair included sensors to detect forces, accelerations, as well child and chair movement. Children with spinal cord injury and typically developing children (2–12 years), recruited under an approved IRB protocol, were observed rocking while sensor and electromyography data were collected from arm, leg, and trunk muscles. Features from sensor data were used to predict muscle activation using multiple linear regression, regression learning, and neural network modeling. Correlation analysis examined individual sensor contributions to predictions. Results: Neural network models outperformed regression models. Multiple linear regression predictions significantly correlated ( p < 0.05) with targets for four of eleven children with SCI, while decision tree regression predictions correlated for five children. Neural network predictions correlated for all children. Conclusions: Embedded sensors capture useful information about muscle activation, and machine learning techniques can be used to inform therapists. Further work is warranted to refine prediction models and to investigate how well results can be generalized.

Study Design Systematic Review and meta-analysis. Objective To conduct an updated systematic review and meta-analysis of complications associated with different anterior fusion techniques/approaches and adjuvant resources (i.e., computed tomography angiography (CTA), rhBMP-2, and access surgeons). Methods A systematic review was conducted from 1/1/2014-4/1/2024 for studies evaluating the incidence of complications associated with anterior lumbar procedures. Comparisons of complications were made between surgical approach, use of CTA, rhBMP-2, and access surgeons. Meta-analyses were conducted using a generalized linear mixed model. Results 54 studies were included in the final analysis with 8066 patients and an average follow-up of 31.2 months. The overall complication rate associated with anterior lumbar surgery was 13.1%, including an intraoperative complication rate of 3.8%, postoperative complication rate of 7.4%, infection rate of 1.5%, and reoperation rate of 1.7%. Forest plot analysis showed no significant difference in overall complication rates between open and mini-open techniques, although mini-open techniques were associated with lower overall reoperation rates. The use of CTA was associated with an increase in intraoperative and overall complications, and the use of an access surgeon was associated with a decreased risk of reoperation. The use of rhBMP-2 was not associated with overall complication risk. Conclusions While anterior lumbar surgery provides numerous benefits, surgeons and patients alike should be aware of the complication and safety profile prior to surgery. High quality studies are warranted to help elucidate the true benefit of certain techniques and adjuvant resources in reducing complications.

Published: August 2024

Background: The effectiveness of nonsurgical treatment of patellar tendinopathy is questioned due to the conflicting results of placebo-controlled randomized controlled trials (RCTs) in which placebo arms often show impressive results. Purpose: To quantify the magnitude of placebo effect of the different nonsurgical treatments of patellar tendinopathy. We also evaluated the influence of patients and treatments characteristics on the response to the placebo. Study Design: Systematic review; Level of evidence, 1. Methods: We searched PubMed, Web of Science, Embase, Scopus, Cochrane Library, and gray literature databases on May 10, 2023, with no time limitation. RCTs on nonoperative treatment of patellar tendinopathy, including a placebo control arm reporting the evolution of symptoms after placebo administration, were included. A single-arm meta-analysis was performed with the Victorian Institute of Sport Assessment-Patella (VISA-P) at mid-term follow-up (3-6 months) as the primary outcome. The VISA-P score at short-term (1-3 months) and long-term (6-12 months) follow-ups, as well as visual analog scale (VAS) for pain at all 3 time points were also analyzed. A subanalysis based on the type of placebo and a meta-regression were conducted to look for potential determinants of the placebo effect. Risk of bias and level of evidence were also analyzed using the revised tool for risk of bias in randomized trials and Grading of Recommendations Assessment, Development and Evaluation. Results: In total, 14 studies (251 patients) were included. VISA-P score at mid-term follow-up (3-6 months) showed statistically significant improvements of 13 of 100 points ( P = .001). The change at short-term follow-up (1-3 months) was not statistically significant, whereas at long-term follow-up (6-12 months) it was 27 of 100 points ( P < .001). Regarding VAS, results were statistically significant only at mid-term (MD = −1.5/10; P = .02) and long-term (MD = −3.2/10; P < .001) follow-ups. The meta-regression showed positive correlations between the response to placebo and the follow-up length ( P < .001) and the effect size in the experimental group ( P = .006). The level of evidence was moderate for mid- and long-term results and low for short-term results. Conclusion: The placebo effect for nonsurgical treatments of patellar tendinopathy is long-lasting (up to 12 months) and statistically and clinically significant. It has a perceived and true component and differs among treatments. The duration of follow-up and the effect size of experimental groups correlate with the magnitude of the placebo component, underlining the importance of RCTs to determine the effectiveness of new treatments of patellar tendinopathy.
Facilitators, Barriers, Conditions, and Recommendations of Pediatric Nurses Reassigned to Adult Care During COVID-19 Pandemic: A Mixed Methods Study
Authors: Pestana-Santos Marcia , Catlin Anita , Mendes Joana 
Published: August 2024

Aims: To describe the conditions, facilitators, barriers, and recommendations of pediatric nurses reassigned to adult care during the COVID-19 pandemic. Background: During COVID-19 pandemic, nurses who were certified, received advanced education, and with years of experience in their fields were asked to, or mandated to, care for adult patients, often with COVID-19 and in intensive care units. Introduction: Nurses struggled with this transition worldwide. Literature searches reflected no guidance in specialty reassignment during a pandemic. Methods: International, mixed method, convergent study using GRAMMS Mixed Methods framework. Two instruments disseminated internationally during 2021 on Survey Monkey© in three languages: (1) Researcher-developed, validated, feelings, beliefs, circumstances, and recommendations survey, (2) Medical-surgical skills survey from Canadian Association of Schools of Nursing. Integrated quantitative and qualitative design for investigatory depth. Analysis using SocialSciences calculator© and Narrative Inquiry methodology. Meleis's Transitions theory provided framework. Results: A total of 122 nurses from 12 countries responded. Sixty-four percent of pediatric nurses reported they were mandated to work with adults with no choice; 64% received no preparation for change in specialty. Respondents reported suffering, absence of training to care for adults, lack of COVID-19 related skills such as care of ventilated patient, proning, mental health support, palliative care, or comforting families of the dying. Ninety-two percent recommended improvement, advising advance planning for transition in assignments, making transitions smoother, and diminishing number of transitions. National and international policies on floating supported the participants’ recommendations. Discussion: Study reports challenges experienced by nurses reassigned outside of their specialties without training or preparation and offers critical recommendations to ensure both nurse and patient safety during future disasters or pandemics. Conclusion/Implications Nursing and Health Policy: Planning for quality nursing care during transitions between specialties is possible. Staff nurses must be included, trained, and prepared. Literature on floating provides solid background for moving nurses between specialties.

Objective Binge drinking and heavy alcohol use are highly prevalent among college students. During the COVID-19 pandemic, due to lockdown restrictions and other challenges, many college students were burdened with loneliness, which can contribute to chronic stress, and substance use. The current study explores the association between loneliness and various levels of alcohol use among college students in the rural, underserved region of Central Appalachia, USA. Methods Data were collected from a regional sample (n = 320) of college age adults, age 18-25 in the Central Appalachian region. The UCLA-3 item Loneliness Scale (UCLA-3) was used in the study to evaluate loneliness. Logistic regression analysis was conducted to assess the association between levels of loneliness and three separate outcomes, including past year binge drinking, past year heavy alcohol use, and past year weekly alcohol use. Results Overall, 25.5% of the participants reported severe loneliness, 33.6% reported moderate, and 40.9% reported low levels of loneliness. Results of the adjusted models revealed that severe loneliness was associated with higher odds of heavy alcohol use (AOR = 1.89, 95% CI [1.02, 3.50]) and binge drinking (AOR = 2.96, 95% CI [1.16, 7.51]), and not associated with weekly alcohol use. Conclusion The study found that higher levels of loneliness were linked to both binged drinking and heavy alcohol use. Further efforts for counseling and treatment among college students who are burdened with severe loneliness should be considered. The chronic stress associated with severe loneliness needs to be further addressed, particularly among emerging adults.
