Published: March 2023

In this paper, a research on theoretical analysis and finite element simulation of the damping sandwich composite plate with fixed support condition is carried out, and the dynamic characteristics of composite plates are explored by modal experiments. The vibration equilibrium equation of damping sandwich composite plate with fixed support condition is derived by combining first-order shear deformation theory, variational principle, and Hamilton principle. A set of modal basis functions satisfying the fixed support condition are established. The analytical solution is obtained via Galerkin weighted residual theory. The influence of structural parameters on the free vibration characteristics of the sandwich composite plates is investigated based on the mutual verification of theoretical calculation, numerical simulation, and modal test results. When the damping layer (0.2 mm) is located on the surface of the skin (2 mm), the first-order mode frequency and first-order loss factor are 196.66 Hz and 0.01, respectively. When the damping layer is in the neutral layer, the first-order mode frequency and first-order loss factor are 189.99 Hz and 0.14, respectively. Compared with the damping layer in the skin, the first-order mode frequency is reduced by 3.39%, while the first-order loss factor is 14 times higher. The results show that the damping performance of the structure is optimal when the damping layer is located in the neutral layer, and the structural stiffness is higher when the damping layer is close to the skin. The work provides theoretical guidance for the development and application of lightweight composite structures with large damping and high stiffness.

Published: March 2023

Cotton, polyester, and polyethylene terephthalate are the most common types of polymers that produce huge wastes. The circularity of these post-consumer (PC) waste faces operational problems during processing. In this innovative research, the relationship between circularity, surface characterization, mechanical and tribological testing of fiber reinforced (cotton, polyester), and particulate (polyethylene terephthalate) composites is explored for industrial pilot production. Cutting model can control the size of fibers during grinding. The fiber reinforced composites (FRCs) with 10% (by weight) fiber loadings are found as operational candidates for structural, automotive, and medical applications due to suitable tensile strength (26–29 MPa), percentage of extension (10%) and abrasive wear (3 × 10−6 mm3/Nm). An increase in fiber content produces micro-defects like asperities, rough areas, voids, cracks, and pits in recycled composites. Therefore, the particulate and FRCs with 40% (by weight) fiber loadings become hard and brittle. However, these composites (especially with 40% wt. fiber loadings) exhibit reasonable elastic modulus (1526–2751 MPa) and abrasive wear (6.5 × 10−6 mm3/Nm). The ductile to brittle transition effect has appeared in all composites (with 30% wt. fiber content) due to continuous fiber addition, micro-defects creation and dual phase presence. In conclusion, natural and synthetic PC wastes can be utilized for sustainable processing of commercial polymer composites. Moreover, injection molding, polymer characterization, tensile testing, abrasion evaluation, and regression analysis can be introduced for the transformation of open-loop into closed-loop manufacturing.

Background: Postpartum Family Planning (PPFP), which aims to prevent high risk unintended and closely spaced pregnancies during the first year following childbirth, is one of the highest impact interventions to avoid increased risk of premature birth, low birth weight, fetal and neonatal death, and adverse maternal health outcomes. This study aimed to assess the combined effect of a package of interventions on the use and quality of PPFP services at Y12HMC, Addis Ababa Ethiopia. Method: Cross-sectional study design was conducted to evaluate the effect of the package of chosen interventions: creating a private counseling space near the postpartum ward and providing training for health care providers on the WHO decision tool kit and Long Acting Contraceptive Methods (LACM). Interviews were conducted with 470 women (235 before and 235 after the intervention). Frequency tables and graphs were used to describe the study variables and statistical significance between pre and post intervention indicators was declared at P value <.05 Results: From 470 participants, 421 respondents participated which makes response rate of 90%. The majority of the participants were in the age category 20 to 29 years, married/lived together, completed at least primary education and had more than one child both at baseline and post intervention. The proportion of women who chose PPFP increased from 55.8% at baseline to 69% after the intervention. The most preferred contraceptive method was implant. The overall service satisfaction level of the study participants was 95.4% post intervention, significantly higher than at baseline (78%, P < .05). Providers indicated that clients are satisfied with the service and that the institutional structure is appropriate for delivering integrated services following the intervention. Conclusion: This study demonstrated that quality improvement interventions like creating a private counseling space and providing training using WHO decision tool kit can achieve significant improvement on satisfaction of clients and PPFP uptake

Published: March 2023

Objective: To measure changes in micronutrient adequacy and diet quality in healthcare and university employees who underwent a 10-week teaching kitchen program. Methods: Thirty-eight healthcare and university employees participated in a 10-week teaching kitchen program. Twenty-seven completed self-administered, 24-hour dietary recalls to measure dietary intake at baseline and 3-months. Micronutrient adequacy and diet quality was assessed using Dietary Reference Intakes (DRIs) and the Healthy Eating Index (HEI). Results: Seventy percent of participants were classified as low or moderate micronutrient adequacy at baseline. The proportion of participants with high micronutrient adequacy increased from 30% to 48% at 3-month follow-up. Total HEI and most HEI components increased at follow-up; with a statistically significant increase in seafood/plant protein score ( P = .007). Conclusions and Implications for Practice: Our results suggest an inadequacy in micronutrient intake in university and healthcare employees and that teaching kitchens may help improve micronutrient adequacy and diet quality.

Published: March 2023

Background: To our knowledge, no nationwide epidemiological study of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) has been conducted. Objective: We examined the epidemiology and clinical features of MOGAD in Japan. Methods: We distributed questionnaires on the clinical characteristics of patients with MOGAD to neurology, pediatric-neurology, and neuro-ophthalmology facilities throughout Japan. Results: In total, 887 patients were identified. The estimated number of total and newly diagnosed MOGAD patients was 1,695 [95% confidence interval (CI): 1483–1907] and 487 (95% CI: 414–560), respectively. The estimated prevalence and incidence were 1.34/100,000 (95% CI: 1.18–1.51) and 0.39/100,000 (95% CI: 0.32–0.44), respectively. The median age at onset was 28 years (range: 0–84 years). At onset, optic neuritis was present in approximately 40% of patients, irrespective of the onset age. Acute disseminated encephalomyelitis was more frequent in younger patients, whereas brainstem encephalitis, encephalitis, and myelitis were more frequent in elderly patients. Immunotherapy was highly effective. Conclusion: The prevalence and incidence rates of MOGAD in Japan are similar to those in other countries. Notable characteristics such as the preferential occurrence of acute disseminated encephalomyelitis in children exist; however, general characteristics including symptoms and treatment response are common irrespective of the onset age.

Published: March 2023

Background Exercise positively affects multiple sclerosis (MS) symptoms, physiological systems, and potentially cognition. However, an uninvestigated “window of opportunity” exists for exercise therapy early in the disease. Objective This study presents secondary analyses from the Early Multiple Sclerosis Exercise Study, and aims to investigate the efficacy of exercise on physical function, cognition, and patient-reported measures of disease and fatigue impact early in the disease course of MS. Methods This randomized controlled trial (n = 84, time since diagnosis <2 years) included 48 weeks of aerobic exercise or an active control condition (health education) and between-group changes are based on repeated measurement mixed regression models. Physical function tests included measures of aerobic fitness, walking (6-minute walk, Timed 25-foot walk, Six-spot step test), and upper-limb dexterity. Tests of processing speed and memory evaluated cognition. The questionnaires Multiple Sclerosis Impact Scale and Modified Fatigue Impact Scale assessed perception of disease and fatigue impact. Results Following early exercise aerobic fitness showed superior between-group physiological adaptations (4.0 [1.7; 6.3] ml O2/min/kg; large effect size [ES = 0.90]). No other outcomes showed significant between-group differences, yet all measures of walking and upper-limb function showed small-to-medium effect sizes in favor of exercise (ES = 0.19−0.58). Overall disability status as well as cognition were unaffected by exercise, whereas perception of disease and fatigue impact were reduced in both groups. Conclusion In early MS, 48 weeks of supervised aerobic exercise seem to positively modify physical function, but not cognitive function. Perception of disease and fatigue impact may be modifiable by exercise in early MS. Trial registration: Clinicaltrials.gov (identifier: NCT03322761).

Background Herd immunity against measles is essential to interrupt measles transmission, and this can only be attained by reaching at least 95% coverage for each of the 2 doses of measles vaccine provided in infancy and early childhood age group. It is important to provide everyone with 2 doses of the measles vaccine in order to effectively safeguard the population. Despite this, little is known about the second dosage of the measles vaccine utilization status and the factors that affect it. Therefore, this study aimed to assess second dose of measles vaccination utilization and its associated factors among children aged 24–35 months in Jabitehnan district, 2020. Methods A community-based cross-sectional study design was conducted at Jabitehnan District, Northwest Ethiopia, from September 1st, 2020 to October 1st, 2020. Systematic random sampling technique was used to select 845 mothers/caregivers who had children aged 24–35 months. Both bi-variable and multivariable logistic regression was fitted to identify the determinant factors of second dose measles vaccination utilization. Finally, the statistical significant variables were declared by using 95% CI and P value less than .05 in the multivariable logistic regression analysis. The Hosmer and Lemeshow test was used to check the model’s fit to the data, and the variance inflation factor was used to assess multi-collinearity. Results The overall second dose of measles vaccination utilization was 48.1%, (95% CI: 44.7-51.6). Mothers with primary school education (AOR = 1.91, 95% CI: 1.15-3.17), information about MCV2 (AOR = 6.53, 95% CI: 4.22-10.08), distance from vaccination site (AOR = 3.56, 95% CI: 2.46-5.14), knowledge about immunization (AOR = 1.935, 95% CI: 1.29-2.90), and favorable attitude about immunization (AOR = 5.19, 95% CI: 3.25-8.29) were significantly associated factors with second dose of measles vaccination utilization. Conclusion Second dose measles vaccination utilization in the district was lower than the national target. Maternal education, distances from vaccination site, information about MCV2, and knowledge about immunization were significantly associated variables with second dose measles vaccination utilization. Therefore, in order to increase the utilization of the second dose of the measles vaccine, improved health education and service expansion to difficult-to-reach areas are required.

Published: March 2023

Background Thoracic aortic aneurysm (TAA) is a serious vascular disease causing the death of elder people. Accumulating studies have reported that circular RNAs (circRNAs) are implicated in the regulation of aortic aneurysms. However, the role of circ_0000595 in the progression of TAA is still unclear. Methods Quantitative real-time PCR (qRT-PCR) and western blotting were implemented to assess circ_0000595, microRNA (miR)-582-3p, guanine nucleotide-binding protein alpha subunit (ADAM10), PCNA, Bax, and Bcl-2 expression. The proliferation of vascular smooth muscle cells was determined using cell counting kit 8 (CCK-8) and 5-ethynyl-2-deoxyuridine (EdU). Cell apoptosis was measured using flow cytometry, and caspase-3 activity was analyzed using a commercial kit. After bioinformatics analysis, the interaction between miR-582-3p and circ_0000595 or ADAM10 was validated using a dual-luciferase reporter and RNA immunoprecipitation. Results As compared with controls, TAA tissues and CoCl2-induced VSMCs displayed high expression of circ_0000595 and ADAM10, and low expression of miR-582-3p. CoCl2 treatment evidently suppressed VSMC proliferation and promoted VSMCs apoptosis, and these impacts were reverted by circ_0000595 knockdown. Circ_0000595 acted as a molecular sponge for miR-582-3p, and circ_0000595 silencing-mediated influences in CoCl2-induced VSMCs were overturned by miR-582-3p inhibitor. ADAM10 was confirmed as a target gene of miR-582-3p, and miR-582-3p overexpression-induced influence was almost restored by overexpressed ADAM10 in CoCl2-induced VSMCs. Besides, circ_0000595 contributed to ADAM10 protein expression by sponging miR-582-3p. Conclusion Our data verified that circ_0000595 silencing might attenuate CoCl2-mediated impacts in VSMCs by regulating the miR-582-3p/ADAM10 axis, providing new potential roads for treating TAA.
Examining arts and creativity in later life and its impact on older people’s health and wellbeing: a systematic review of the evidence
Authors: McQuade L , O’Sullivan R 
Published: March 2023

Aim: There is a growing recognition of the contribution that participation in group-based arts and creativity interventions makes to our health and wellbeing. Despite this acknowledgement, more empirical investigation is required to more fully understand its impact. The aim of this mixed-method systematic review was to develop a better understanding of the evidence on the impact of arts and creativity on older people’s physical and psychological health and wellbeing. Method: Extensive searches of 14 electronic bibliographic databases were carried out using predefined search criteria for the period 2013–2020. Ninety-three studies were included within the review and appraised using the Mixed Methods Appraisal Tool (MMAT). Results: Dance was the most common form of arts identified within studies, followed by music and singing. Dance was associated with improved balance, lower body physical strength, flexibility, and aerobic fitness in older adults. Promising evidence showed that music and singing on a regular basis were associated with improved cognitive function, quality of life, affective states and a sense of wellbeing in older adults. Preliminary evidence showed that visual and creative arts were associated with reduced feelings of loneliness, improved sense of community and social connectedness. Initial evidence showed that theatre and drama were associated with emotional wellbeing; however, more evidence is required in this area. Conclusion: The evidence shows that participation in group-based arts and creativity can have positive physical, mental, and social health impacts for older adults, ageing and for population health. These findings support the importance of participation in the arts for older adults, especially for the promotion of positive health and for the prevention, or mitigation, of ill health in later life for both public health and the arts and creativity agenda.

Published: March 2023

Purpose: A common question faced by clinicians is when a child may return to sport after treatment for a pediatric forearm fracture. There are few published recommendations and fewer supported by evidence. The aims of this study were to summarize existing published recommendation for return to sport after pediatric forearm fractures and to conduct a survey to determine usual clinical recommendations. Methods: A scoping review was performed on Ovid MEDLINE, Cochrane Central Register of Controlled Trials, Embase, Scopus, and Google Scholar in accordance with the Joanna Briggs Institute guidelines. In addition, 64 orthopedic surgeons were anonymously surveyed asking for recommendations regarding return to sport after pediatric forearm fractures. Participants were to assume children were 9 years old and played a sport with an average risk of forearm injury. Results: Twenty-two publications for return to sport were retrieved. Children with distal radius buckle fractures safely commonly returned to sport by 4 weeks after initial injury, while survey respondents recommended over 6 weeks. Survey respondents valued fracture stability the highest when making return to sport recommendations. Children with simple, metaphyseal, single-bone fractures were usually allowed to return to sport at 8–10 weeks post-injury. Diaphyseal and complete fractures were prescribed longer return to sport intervals. Australian respondents also prescribed longer return to sport intervals. Conclusion: Children with distal radius buckle fractures may return to sport by 4 weeks after initial injury, sooner than recommended. Published recommendations remain limited for other fractures. However, our survey suggests children with simple, metaphyseal, single-bone fractures may return to sport at 8–10 weeks. Children with diaphyseal and complete fractures should abstain from sport for longer than metaphyseal and greenstick fractures, respectively. Level of evidence: level V

Background: The Stanford Youth Diabetes Coaching Program (SYDCP) is an evidence-based program led by health care professionals to teach healthy youth who then coach family members with diabetes or other chronic conditions. This purpose of this study is to evaluate a Community Health Worker (CHW)-led implementation of the SYDCP for low-income Latinx students from underserved agricultural communities. Method: CHWs were trained and virtually led 10 training sessions virtually during the COVID-19 for Latinx students who were recruited from high schools in agricultural regions of Washington state. Feasibility measures include recruitment, retention, class attendance, and successful coaching of a family member or friend. Acceptability was measured by responses on the post-training survey. Effectiveness was evaluated by pre-post changes in measures used in prior studies of the SYDCP such as level of activation and diabetes knowledge. Results: Thirty-four students were recruited, 28 completed the training and 23 returned both pre- and post-surveys. Over 80% of students attended 7 or more classes. All met with a family or friend and 74% met with them weekly. Approximately 80% of the students rated the program’s usefulness as “very good” or “excellent.” Pre-post increases in diabetes knowledge, nutrition-related behaviors, resilience, and activation were significant and similar to those observed in prior published studies of the SYDCP. Conclusions: Findings support the feasibility, acceptability, and effectiveness of a CHW-led implementation of the SYDCP in underserved Latinx communities using a virtual remote model.

Published: March 2023

Only a few researchers have used qualitative methods to explore Latinx students' experiences and testimonials with their high school counselors. These studies, conducted more than 10 years ago, found that Latinx students reported negative experiences with high school counselors, such as low academic expectations and lack of availability. In the current study, we interviewed eight Latinx college students from the southern United States to learn about their experiences with their high school counselors. The following five themes emerged from interpretative phenomenological analysis of the data: (a) high academic expectations, (b) advisement, (c) lack of availability and accessibility, (d) no social or emotional support, and (e) limited career development. Two crucial implications from this study are that school counselors need to be engaged in all activities aligned with the American School Counselor Association guidelines and should remind Latinx students regularly about school counselors’ essential roles and responsibilities in academic, career, and social/emotional development. We discuss additional implications.
