Abstract
Background
Current literature reports a gap between development of effective interventions to promote physical activity and the systematic uptake into real-world settings. Factors relating to implementation and scale-up of physical activity interventions have been examined, however the perspectives of multiple stakeholders from different domains are not well researched. The purpose of this study was to examine the perceived factors related to physical activity intervention implementation and scale-up in different domains from different stakeholders on the island of Ireland.

Methods
Practitioners, researchers, funders and policy makers in Ireland were invited to take part in a semi-structured interview exploring factors related to the implementation and scale-up of eleven different physical activity interventions. A thematic analysis was conducted to identify factors related to the implementation and scale-up of the included interventions. The data collection and analysis were guided by the Consolidated Framework for Implementation Research.

Results
Thirty-eight participants took part in the interviews which identified factors related to 1) intervention planning and practical considerations; 2) organisational structures, staffing and resources related to delivery; 3) reflection, evaluation and updating of the intervention; and 4) practical consideration related to scale-up. Furthermore, participants referred to the ongoing commitment, engagement, and support needed throughout the implementation process.

Conclusions
Future research and practice needs to consider how different factors are experienced at different implementation stages and by the different stakeholder groups involved. The findings highlight multiple inter-related factors that influence the implementation and scale-up of physical activity interventions, but also identifies many strategies that can be utilised to aid future successes.

Abstract
Background
Increasing evidence suggests that patients with Parkinson's disease (PD) present with peripheral autonomic dysfunction (AutD) that even precedes motor deficits, through which α-synuclein can spread to the central nervous system. However, the pathological mechanisms underlying AutD in prodromal PD remain unclear. Here, we investigated the role of α-synuclein and its interplay with the activation of Schwann cells (SCs) of the vagus nerve in AutD.

Methods
Rats were subjected to injection with adeno-associated viruses containing the human mutated A53T gene (AAV-A53T) or an empty vector into the left cervical vagus nerve and evaluated for gastrointestinal symptoms, locomotor functions, intestinal blood flow, and nerve electrophysiology. Further, we examined the impact of α-synucleinopathy on vagus nerves, SCs, and central nervous system neurons using electron microscopy, immunofluorescence, immunohistochemistry, and western blot. Finally, the role of Toll-like receptor 2 (TLR2) in regulating the neuroinflammation in the vagus nerve via MyD88 and NF-κB pathway was determined using genetic knockdown.

Results
We found that rats injected with AAV-A53T in the vagus nerve exhibited prominent signs of AutD, preceding the onset of motor deficits and central dopaminergic abnormalities by at least 3 months, which could serve as a model for prodromal PD. In addition, reduced intestinal blood flow and decreased nerve conduction velocity were identified in AAV-A53T-injected rats, accompanied by disrupted myelin sheaths and swollen SCs in the vagus nerve. Furthermore, our data demonstrated that p-α-synuclein was deposited in SCs but not in axons, activating the TLR2/MyD88/NF-κB signaling pathway and leading to neuroinflammatory responses. In contrast, silencing the TLR2 gene not only reduced inflammatory cytokine expression but also ameliorated vagal demyelination and secondary axonal loss, consequently improving autonomic function in rats.

Conclusions
These observations suggest that overexpression of α-synuclein in the vagus nerve can induce symptoms of AutD in prodromal PD, and provide support for a deeper understanding of the pathological mechanisms underlying AutD and the emergence of effective therapeutic strategies for PD.

Published: February 2023

AbstractThoracic aortic pseudoaneurysm caused by Brucella melitensis is extremely rare with extremely few cases reported to date. Herein, we present the case of a 65 year-old man with a huge pseudoaneurysm of the proximal descending thoracic aorta, involving the left subclavian artery and distal arch. Surgery was performed to replace the proximal descending aorta with a self-made bovine pericardial duct and the left subclavian artery with a 10 mm artificial vessel under deep hypothermic circulatory arrest; the patient recovered uneventfully. However, continued follow-up is required for long-term results.

Published: February 2023

Abstract
Background
Family members of patients with eating disorders, especially their mothers, experience heavy caregiving burdens associated with supporting the patient. We predict that increasing caregivers’ support will have a positive effect on their active listening attitudes, mental health, loneliness, and self-efficacy. This study aimed to investigate differences in mothers’ active listening attitudes, mental health, loneliness, and self-efficacy improvements between mothers who did and did not experience increased perceived social support.

Main body
Participants were mothers of patients with eating disorders. Questionnaires for this cohort study were sent to the participants’ homes at three time points (baseline, 9 months, and 18 months). The Japanese version of the Social Provision Scale (SPS-10) was used to evaluate social support, the Active Listening Attitude Scale (ALAS) for listening attitude, the UCLA Loneliness Scale (ULS) for loneliness, the General Self-Efficacy Scale (GSES) for self-efficacy, the Beck Depression Inventory (BDI-II) for depression symptoms, and the K6 for psychological distress. An unpaired t-test was used to determine whether participants’ status differed between the groups that did and did not experience increased perceived social support. The mean age of the participants was 55.1 ± 6.7 (mean ± SD) years. The duration of their children’s eating disorders was 7.6 ± 5.5 years. The degree of improvement for each variable (active listening attitude, loneliness, self-efficacy, depressive symptoms, and mental health) was the difference in each score (ALAS, ULS, GSES, BDI-II, and K6) from T1 to T3. The degree of improvement in active listening attitude and loneliness was significantly greater in the improved social support group than in the non-improved social support group (p < 0.002 and p < 0.012, respectively).

Conclusions
Our findings indicate that increasing mothers’ perceptions of social support will be associated with improving their active listening attitudes and loneliness.

AbstractBackgroundThis study aimed to analyze all the patients who contacted the hospital’s pediatric poison control center (PPCC) for exposure to ibuprofen and acetaminophen, in order to assess the incidence of any adverse reactions.MethodsWe retrospectively reported the clinical data of children who accessed the PPCC of the Bambino Gesù Children’s Hospital, IRCCS, Rome, from January 1, 2018 to September 30, 2022 due to wrong, accidental or intentional intake of inappropriate doses of acetaminophen and/or ibuprofen. In addition, we compared patients according to the intake of one of the two drugs and reported the trimestral distribution of cases during the study period.ResultsA total of 351 patients accessed the PPCC during the study period. The median age was 3.0 years. Most patients were females (57.8%). The most common reason for inappropriate oral intake of paracetamol or ibuprofen was a wrong use or an accidental intake (78.6%), with a fifth of patients taking the drug with suicidal intent (21.1%). According to the PPCC evaluation, most patients were not intoxicated (70.4%). Hospitalization was required for 30.5% of patients. Adverse reactions were reported in 10.5% of cases, with a similar incidence in patients who took paracetamol or ibuprofen. Nausea and vomiting were the most commonly reported adverse reactions. A higher frequency of moderate intoxication was found in patients who took paracetamol compared to ibuprofen (p = 0.001). The likelihood of intoxication was also higher in the paracetamol cohort. A spike of cases was registered at the end of 2021.ConclusionsWe analyze exposures to the two most commonly used pediatric molecules, paracetamol and ibuprofen, to assess the frequency of adverse reactions. We demonstrated that these relatively “safe” drugs may be associated with intoxications and adverse reactions when inappropriately administered.

Abstract
Background
Eradication of Helicobacter pylori provides the most effective treatment for gastroduodenal diseases caused by H. pylori infection. Clarithromycin, a member of the macrolide family, still remains the most important antibiotic used in H. pylori eradication treatment. But the increasing prevalence of clarithromycin resistant H. pylori strains due to point mutations in the V region of the 23S rRNA, poses a great threat in treating the ailing patients. So, we aimed for PCR-mediated rapid detection of the point mutation at 2143 position of 23S rRNA gene in H. pylori that is relevant to clarithromycin resistance from culture and simultaneously from biopsy specimens to avoid the empirical treatment.

Results
Newly developed PCR assay using DNA of pure culture detected point mutation in 23S rRNA gene in 21 (8.04%) of 261 clinical strains tested. The agar dilution method showed that all these 21 strains were resistant to clarithromycin indicating the perfect match of the PCR based results. Additionally, the sequencing study also identified the A to G mutation at 2143 position in 23S rRNA gene of the resistant strains only. Consequently, the newly developed Nested-ASP-PCR dealing directly with 50 biopsy specimens demonstrated 100% sensitivity and specificity with the findings of agar dilution method taken as Gold standard. Bioinformatics based analysis such as accessibility analysis and dot plot clearly stated that the base pairing probability has increased due to mutation. Computational studies revealed that the point mutation confers more stability in secondary structure due to conversion of loop to stem. Furthermore, interaction studies showed binding affinity of the CLR to the mutant type is weaker than that to the wild type.

Conclusion
This assay outlines a rapid, sensitive and simple approach to identify point mutation that confers clarithromycin resistance as well as clarithromycin sensitive strains, providing rapid initiation of effective antibiotic treatment. Additionally, it is simple to adopt for hospital based diagnostic laboratories to evaluate the degree of regional clarithromycin resistance from biopsy specimens itself. Furthermore, in silico studies provide evidence or a signal that the prevalence of clarithromycin resistance may rise in the near future as a result of this point mutation.

Abstract
Background
Fetal growth restriction (FGR) is associated with deficits in the developing brain, including neurovascular unit (NVU) dysfunction. Endothelial colony forming cells (ECFC) can mediate improved vascular stability, and have demonstrated potential to enhance vascular development and protection. This investigation examined whether ECFCs from human umbilical cord blood (UCB) enhanced NVU development in FGR and appropriate for gestational age (AGA) fetal sheep.

Methods
Twin-bearing ewes had surgery performed at 88–90 days’ gestation, inducing FGR in one fetus. At 113 days, ECFCs (1 × 107 cells) cultured from human UCB were administered intravenously to fetal sheep in utero. At 127 days, ewes and their fetuses were euthanised, fetal brains collected, and NVU components analysed by immunohistochemistry.

Results
Twenty-four fetal lambs, arranged in four groups: AGA (n = 7), FGR (n = 5), AGA + ECFC (n = 6), and FGR + ECFC (n = 6), were included in analyses. FGR resulted in lower body weight than AGA (P = 0.002) with higher brain/body weight ratio (P = 0.003). ECFC treatment was associated with increased vascular density throughout the brain in both AGA + ECFC and FGR + ECFC groups, as well as increased vascular–astrocyte coverage and VEGF expression in the cortex (P = 0.003, P = 0.0006, respectively) and in the subcortical white matter (P = 0.01, P = 0.0002, respectively) when compared with the untreated groups.

Conclusions
ECFC administration enhanced development of NVU components in both the AGA and FGR fetal brain. Further investigation is required to assess how to optimise the enhanced angiogenic capabilities of ECFCs to provide a therapeutic strategy to protect the developing NVU against vulnerabilities associated with FGR.

Background The COVID-19 pandemic placed considerable strain on the healthcare system, leading to the re-allocation of resources and implementation of new practice guidelines. The objective of this study is to assess the impact of COVID-19 guideline modifications on head and neck cancer (HNC) care at two tertiary care centers in Canada. Methods A retrospective cohort study was conducted. HNC patients seen at two tertiary care centers before and after the onset of the COVID-19 pandemic (pre-pandemic: July 1st, 2019, to February 29th, 2020; pandemic: March 1st, 2020, to October 31st, 2020) were included. The pre-pandemic and pandemic cohorts were compared according to patient and tumor characteristics, duration of HNC workup, and treatment type and duration. Mean differences in cancer care wait times, including time to diagnosis, tumor board, and treatment as well as total treatment package time and postoperative hospital stay were compared between cohorts. Univariate and multivariate analyses were used to compare characteristics and outcomes between cohorts. Results Pre-pandemic (n = 132) and pandemic (n = 133) patients did not differ significantly in sex, age, habits, or tumor characteristics. The percentage of patients who received surgery only, chemo/radiotherapy (CXRT) only, and surgery plus adjuvant CXRT did not differ significantly between cohorts. Pandemic patients experienced a significant time reduction compared to pre-pandemic patients with regards to the date first seen by a HNC service until start of treatment ([Formula: see text] [Formula: see text]  = 48.7 and 76.6 days respectively; p = .0001), the date first seen by a HNC service until first presentation at tumor board ([Formula: see text] [Formula: see text]  = 25.1 and 38 days respectively; p = .001), mean total package time for patients who received surgery only ([Formula: see text] [Formula: see text]  = 3.7 and 9.0 days respectively; p = .017), and mean total package time for patients who received surgery plus adjuvant CXRT ([Formula: see text] [Formula: see text]  = 80.2 and 112.7 days respectively; p = .035). Conclusion The time to treatment was significantly reduced during the COVID-19 pandemic as compared to pre-pandemic. This transparent model of patient-centered operative-room prioritization can serve as a model for improving resource allocation and efficiency of HNC care during emergency and non-emergency scenarios.

AbstractIntroductionPremenstrual syndrome (PMS) is a common condition that affects social and psychological well-being of women. The risk of PMS is higher among obese women. The aim of this study was to identify the factors that influence the severity of PMS in women with central obesity.Materials and methodsThis cross-sectional study was performed on 30–50 year-old women with abdominal obesity (waist circumference > 80 cm). The following data were collected: demographic data, anthropometric measurements, premenstrual symptoms screening tools, semi-quantitative food frequency questionnaire, 42-item depression, anxiety, and stress questionnaire (DASS-42), as well as serum vitamin D, and renal function tests.ResultsA total of 139 women (mean age of 41.40 ± 7.39 years old) participated in the study. The prevalence of mild, moderate and severe premenstrual symptoms was 38.7% (55/142), 31.7% (45/142) and 27.5% (39/142), respectively. There was no significant difference between the groups in terms of anthropometric measurements and energy-adjusted nutrient intakes (p > 0.05). There was a significant relationship between moderate PMS and energy-adjusted saturated fatty acid (SFA) (p = .018, OR = .010 and 95% CI for OR: < .001 and .452), and energy-adjusted riboflavin (p = .042, OR = .005, 95% CI for OR: < .001 and .821), and between severe PMS and age (p = .034, OR = .906, 95% CI for OR: .826 and .993), and energy-adjusted monounsaturated fatty acid (MUFA) intake (p = .041, OR = 23.789, 95% CI for OR: 1.138 and 497.294).ConclusionHigh intakes of MUFA and younger age were associated with a greater severity of PMS, while riboflavin intake was associated with reduced PMS severity.

Abstract

Introduction
Personalized disease management informed by quantitative risk prediction has the potential to improve patient care and outcomes. The integration of risk prediction into clinical workflow should be informed by the experiences and preferences of stakeholders, and the impact of such integration should be evaluated in prospective comparative studies.
The objectives of the IMplementing Predictive Analytics towards efficient chronic obstructive pulmonary disease (COPD) treatments (IMPACT) study are to integrate an exacerbation risk prediction tool into routine care and to determine its impact on prescription appropriateness (primary outcome), medication adherence, quality of life, exacerbation rates, and sex and gender disparities in COPD care (secondary outcomes).

Methods
IMPACT will be conducted in two phases. Phase 1 will include the systematic and user-centered development of two decision support tools: (1) a decision tool for pulmonologists called the ACCEPT decision intervention (ADI), which combines risk prediction from the previously developed Acute COPD Exacerbation Prediction Tool with treatment algorithms recommended by the Canadian Thoracic Society’s COPD pharmacotherapy guidelines, and (2) an information pamphlet for COPD patients (patient tool), tailored to their prescribed medication, clinical needs, and lung function. In phase 2, we will conduct a stepped-wedge cluster randomized controlled trial in two outpatient respiratory clinics to evaluate the impact of the decision support tools on quality of care and patient outcomes. Clusters will be practicing pulmonologists (n ≥ 24), who will progressively switch to the intervention over 18 months. At the end of the study, a qualitative process evaluation will be carried out to determine the barriers and enablers of uptake of the tools.

Discussion
The IMPACT study coincides with a planned harmonization of electronic health record systems across tertiary care centers in British Columbia, Canada. The harmonization of these systems combined with IMPACT’s implementation-oriented design and partnership with stakeholders will facilitate integration of the tools into routine care, if the results of the proposed study reveal positive association with improvement in the process and outcomes of clinical care. The process evaluation at the end of the trial will inform subsequent design iterations before largescale implementation.
