ABSTRACT

OBJECTIVE: We designed a simplified total arch reconstruction (s-TAR) technique which could be performed under mild hypothermia (30-32 °C) with distal aortic perfusion. This study aimed to compare its efficacy of organ protection with the conventional total arch reconstruction (c-TAR).

METHODS: We reviewed the clinical data of 195 patients who had ascending aortic aneurysm with extended aortic arch dilation and underwent simultaneous ascending aorta replacement and TAR procedure between January 2018 and December 2022 in our center. 105 received c-TAR under moderate hypothermia (25-28 °C) with circulatory arrest (c-TAR group); rest 90 received s-TAR under mild hypothermia (30-32 °C) with distal aortic perfusion (s-TAR group).

RESULTS: The s-TAR group demonstrated shorter CPB time, cross-clamp time and lower body circulatory arrest time compared with the c-TAR group. The 30-day mortality was 2.9% for the c-TAR group and 1.1% for the s-TAR group (P = 0.043). The mean duration of mechanical ventilation was shorter in the s-TAR group. Paraplegia was observed in 4 of 105 patients (3.8%) in the c-TAR group, while no such events were observed in the s-TAR group. The incidence of temporary neurologic dysfunction was significantly higher in the c-TAR group. The incidence of permanent neurologic dysfunction also showed a tendency to be higher in the c-TAR group, without statistical significance. Furthermore, the incidence of reoperation for bleeding were significantly lower in the s-TAR group. The rate of postoperative hepatic dysfunction and all grades of AKI was remarkably lower in the s-TAR group. The 3-year survival rate was 95.6% in the s-TAR group and 91.4% in the c-TAR group.

CONCLUSIONS: s-TAR under mild hypothermia (30-32℃) with distal aortic perfusion is associated with lower mortality and morbidity, offering better neurological and visceral organ protection compared with c-TAR.

ABSTRACT

BACKGROUND: Breast cancer is the most commonly diagnosed cancer in women worldwide, and underlying mechanistic pathways associated with breast cancer-specific and non-breast cancer-related deaths are of importance. Emerging evidence suggests a role of oxysterols, derivates of cholesterol, in multiple chronic diseases including breast cancer and coronary artery diseases. However, associations between oxysterols and survival have been minimally studied in women diagnosed with breast cancer. In this large breast cancer patient cohort, we evaluated associations between a panel of circulating oxysterols and mortality and recurrence outcomes.

METHODS: Concentrations of 13 circulating oxysterols representing different pathways of cholesterol metabolism were quantified using liquid-chromatography mass-spectrometry. Associations between baseline levels of oxysterols and cause-specific mortality outcomes and recurrence following a breast cancer diagnosis were assessed in 2282 women from the MARIE study over a median follow-up time of 11 years. We calculated hazard ratios (HR) and 95% confidence intervals (CI) using multivariable Cox proportional hazard models and competing risks models.

RESULTS: We observed no associations for circulating oxysterols and breast cancer-specific outcomes. Higher levels of six oxysterols were associated with an increased risk of cardiovascular disease death, including 24S-hydroxycholesterol (alternative bile acid pathway, HR_log2 = 1.73 (1.02, 2.93)), lanosterol (cholesterol biosynthesis pathway, HR_log2 = 1.95 (1.34, 2.83)), 7-ketocholesterol (HR_log2 = 1.26 (1.03, 1.55)), 5α,6α-epoxycholesterol (HR_log2 = 1.34 (1.02-1.77)), and 5a,6β-dihydroxycholestanol (HR_log2 = 1.34 (1.03, 1.76)). After adjusting for multiple comparisons, none of the associations were statistically significant.

CONCLUSION: We provide first evidence on a range of circulating oxysterols and mortality following a breast cancer diagnosis, contributing to a better understanding of associations between different pathways of cholesterol metabolism and prognosis in women with a breast cancer diagnosis. The findings of this study suggest circulating oxysterols may be associated with cardiovascular mortality among women diagnosed with breast cancer. Further studies are needed to evaluate these oxysterols as potential markers of risk for cardiovascular mortality among women with a breast cancer diagnosis as well as their clinical potential.

ABSTRACT

BACKGROUND: Pulmonary carcinoid is a rare diagnosis with surgery remaining the standard treatment of choice. However, resection may impact patients’ daily activities due to decreased lung volume reserve and postoperative pain. Our study aims to compare the impact of different types of surgical resection on the post-operative quality of life with the application of a strict peri-operative pulmonary care program.

METHODS: Patients who underwent surgery for bronchopulmonary carcinoid tumors in a tertiary cancer center between August, 2017 and March, 2020 were identified and demographic data was collected. Patients were contacted via phone for the qualitative and quantitative assessment of pain and quality of life, utilizing the Arabic version of Short-form McGill Pain Questionnaire and Activity of Daily Living (ADL) instrument respectively. Lung reserve was assessed before and after surgery. Statistical analysis used Chi-Square for categorical variables and ANOVA for continuous variables.

RESULTS: A total of 16 patients underwent different type of resection. The majority were male (n = 10; 63%) with a mean age of 44 years (19-81). Most common clinical stage was stage I (n = 12, 75%) with typical carcinoid features recorded in more than half of the cases (n = 11, 69%). Almost all patients underwent surgical excision (n = 15, 94%) with negative resection margin and no major post-operative complications. Bilobectomy was the most frequent procedure (n = 6, 40%) and video-assisted thoracoscopic surgery (VATS) was utilized in 8 patients (50%). Expected changes were recorded in pre- and postoperative pulmonary function test with an average drop of 10 in FEV1 and 14 mL/min/mmHg in DLCO. The majority of patients (n = 15, 94%) were totally independent doing daily activities. Mild intermittent pain was found in 7 patients (44%) who scored an average intensity of 1.6 out of 10.

CONCLUSIONS: Excellent long-term outcomes can be achieved following surgical resection of pulmonary carcinoid tumors with little to no effect on patients’ lung function and quality of life in regard to performance status and post-operative pain when a good peri-operative pulmonary, physical rehabilitation, and pain management programs are adopted and strictly implemented.

ABSTRACT

BACKGROUND: In dentistry, nosocomial infection poses a great challenge to clinicians. The microbial contamination of water in dental unit waterlines (DUWLs) is ubiquitous. Such infected DUWLs can transmit oral microbes in the form of aerosols. Previous studies have suggested treating DUWLs with various disinfectants to reduce cross-contamination. The literature lacks a comparative evaluation of the effect of the use of 0.2% chlorhexidine (CHX) and 0.1% sodium hypochlorite (NaOCl) in DUWLs on aerosolized bacteria generated during dental procedures.

OBJECTIVE: To compare the effect of NaOCl and CHX in DUWLs on aerosolized bacteria generated during restorative and endodontic procedures.

MATERIALS AND METHODS: A total of 132 patients were equally divided into three groups (n = 44 in each group) according to the content of DUWL as follows. Group I-0.1% NaOCl Group II-0.2% CHX Group III-distilled water (Positive control) One-way ANOVA was performed and the Kruskal-Wallis test was used for intergroup comparison.

RESULTS: For the restorative procedure, inter-group comparison of mean colony-forming units (CFU) scores showed a statistically significant difference between the groups (p – .001) with the score of group 3 higher than group 2 followed by group 1. For the endodontics, an inter-group comparison of CFU scores showed a statistically significant difference between the groups (p – .003) with the mean score in group 1 being the lowest and group 3 being the highest.

CONCLUSION: The addition of NaOCl or CHX in DUWLs shows an effective reduction in aerosolized bacteria compared to distilled water.

ABSTRACT

BACKGROUND: Efforts to reduce emergency department (ED) volumes often target frequent users. We examined transitions in care across ED, hospital, and community settings, and in-hospital death, for high system users (HSUs) compared to controls.

METHODS: Population-based databases provided ED visits and hospitalizations in Alberta and Ontario, Canada. The retrospective cohort included the top 10% of all the ED users during 2015/2016 (termed HSUs) and a random sample of controls (4 per each HSU) from the bottom 90% per province. Rates of transitions among ED, hospitalization, community settings, and in-hospital mortality were adjusted for sociodemographic and ED variables in a multistate statistical model.

RESULTS: There were 2,684,924 patients and 579,230 (21.6%) were HSUs. Patient characteristics associated with shorter community to ED transition times for HSUs included Alberta residence (ratio of hazard ratio [RHR] = 1.11, 95% confidence interval [CI] 1.11,1.12), living in areas in the lower income quintile (RHR = 1.06, 95%CI 1.06,1.06), and Ontario residents without a primary health care provider (RHR = 1.13, 95%CI 1.13,1.14). Once at the ED, characteristics associated with shorter ED to hospital transition times for HSUs included higher acuity (e.g., RHR = 1.70, 95% CI 1.61, 1.81 for emergent), and for many diagnoses including chest pain (RHR = 1.71, 95%CI 1.65,1.76) and gastrointestinal (RHR = 1.66, 95%CI 1.62,1.71). Once admitted to hospital, HSUs did not necessarily have longer stays except for conditions such as chest pain (RHR = 0.90, 95% CI 0.86, 0.95). HSUs had shorter times to death in the ED if they presented for cancer (RHR = 2.51), congestive heart failure (RHR = 1.93), myocardial infarction (RHR = 1.53), and stroke (RHR = 1.84), and shorter times to death in-hospital if they presented with cancer (RHR = 1.29).

CONCLUSIONS: Differences between HSUs and controls in predictors of transitions among care settings were identified. Co-morbidities and limitations in access to primary care are associated with more rapid transitions from community to ED and hospital among HSUs. Interventions targeting these challenges may better serve patients across health systems..

ABSTRACT

BACKGROUND: Demonstrating safety and efficacy of new medical treatments requires clinical trials but clinical trials are costly and may not provide value proportionate to their costs. As most health systems have limited resources, it is therefore important to identify the trials with the highest value. Tools exist to assess elements of a clinical trial such as statistical validity but are not wholistic in their valuation of a clinical trial. This study aims to develop a measure of clinical trials value and provide an online tool for clinical trial prioritisation.

METHODS: A search of the academic and grey literature and stakeholder consultation was undertaken to identify a set of criteria to aid clinical trial valuation using multi-criteria decision analysis. Swing weighting and ranking exercises were used to calculate appropriate weights of each of the included criteria and to estimate the partial-value function for each underlying metric. The set of criteria and their respective weights were applied to the results of six different clinical trials to calculate their value.

RESULTS: Seven criteria were identified: ‘unmet need’, ‘size of target population’, ‘eligible participants can access the trial’, ‘patient outcomes’, ‘total trial cost’, ‘academic impact’ and ‘use of trial results’. The survey had 80 complete sets of responses (51% response rate). A trial designed to address an ‘Unmet Need’ was most commonly ranked as the most important with a weight of 24.4%, followed by trials demonstrating improved ‘Patient Outcomes’ with a weight of 21.2%. The value calculated for each trial allowed for their clear delineation and thus a final value ranking for each of the six trials.

CONCLUSION: We confirmed that the use of the decision tool for valuing clinical trials is feasible and that the results are face valid based on the evaluation of six trials. A proof-of-concept applying this tool to a larger set of trials with an external validation is currently underway.

ABSTRACT

OBJECTIVE: To explore the different menstrual and pubertal abnormalities in adolescent females with systemic autoimmune rheumatic diseases (ARD).

METHODS: The study included adolescent girls aged 13-18 years with juvenile idiopathic arthritis (JIA), juvenile systemic lupus erythematosus (JSLE), and juvenile dermatomyositis (JDM) classified according to their international classification criteria. Data were collected from our patients’ files and interpreted with respect to the demographic, clinical, disease assessment parameters, medications used, and the hormonal profile. The aspects of puberty and menstruation were assessed by a gynaecologist with ultrasound evaluation as well. The girls were classified according to their menstrual pattern into those with regular cycles versus abnormal ones. The subgroups were compared and significant variables entered into a logistic regression model to detect the independent predictors.

RESULTS: Twenty-one girls with JSLE were included, besides 23 JIA and 8 JDM cases. Ten patients with JSLE (47.6%) had menstrual abnormalities, whereas only four JIA (17.4%) and 1 JDM girls had these alterations without significant difference between the three groups. The median of the SLICC/ACR damage index was statistically higher in JSLE with abnormal menstrual cycles, similarly were the cumulative steroid dose and puberty onset. No difference was observed between JIA or JDM subgroups concerning the disease parameters, hormonal profile, ultrasound assessment or the treatment lines. The most significant predictor for menstrual abnormalities in JSLE was the SLICC/ACR damage index.

CONCLUSION: Menstrual abnormalities is a common disturbance among adolescent girls with ARDs. The SLICC/ACR damage index is the main determinant for menstrual abnormalities rather than the cumulative steroid use or disease duration in JSLE.

ABSTRACT

BACKGROUND: Absenteeism is consistently higher in public than in private organizations, as is the use of part-time employment. The aim of this study is to identify whether there is a relationship between part-time work and sickness absence at the organizational level.

METHODS: The data is a six-year panel for the full population of Norwegian municipalities (N = 422), linking objective register data on both part-time employment and sickness absence. Using OLS regression with fixed effects for municipality and time, we estimate the statistical effects of the municipalities’ use of part-time work on sickness absence.

RESULTS: The bivariate correlation between percentage position at the municipal level and percentage sickness absence is positive and significant (Pearson’s r = .25, sig LE 0.01). When controlling for fixed effects for municipality and time, as well as municipality economy, municipality size, ratio of female employees in the municipality and characteristics of the general population, the multivariate regression coefficient is still positive but insignificant (coefficient = 1.56, robust standard error = 1.31).

CONCLUSIONS: The main findings are that the organizations’ use of part-time work is unrelated to sickness absence indicating that organizations with extensive use of part-time work do not experience higher levels of absenteeism than those having less extensive use of part-time employees.

ABSTRACT

BACKGROUND: Poor body image is prevalent among adolescents and associated with several negative outcomes for their physical and psychological health. There is a pressing need to address this growing public health concern, yet there are few evidence-informed universal programmes for older adolescents that address contemporary body image concerns (i.e., social media). BodyKind is a four lesson, school-based, teacher led, universal body image programme that incorporates empirically supported principles of cognitive dissonance, self-compassion, compassion for others and social activism, to support positive body image development. Building on previous pilot trials in the USA, this paper outlines the protocol for a cluster randomised control trial (cRCT) and implementation evaluation of the BodyKind programme which was culturally adapted for the Irish cultural context.

METHODS: We aim to recruit 600 students aged 15-17 years in Transition Year (4^th year) across 26 second-level schools in Ireland. Using minimisation, schools will be randomly assigned to receive BodyKind (intervention condition, n=300) or classes as usual (waitlist control, n=300). Teachers in intervention groups will receive training and deliver the programme to students over four weeks, at a rate of one lesson per week. Primary outcomes of body appreciation, body dissatisfaction and psychological wellbeing and secondary outcomes of self-compassion, compassion for others, body ideal internalisation, social justice motives and appearance-based social media use will be assessed at pre-, post- and 2 month follow up. Mediation and moderation analyses will be conducted to identify how and for whom the intervention works best. An implementation evaluation will assess the quality of programme implementation across schools and how this may influence intervention outcomes. Waitlist control schools will receive the programme after the 2-month follow up.

CONCLUSION: This study will be the first to implement a cRCT and an implementation evaluation to assess the impact of this multicomponent school-based body image programme designed to support healthy body image development. If shown to be effective, BodyKind will have the potential to improve adolescent body image and wellbeing and inform efforts to implement sustainable and scalable programmes in schools.

TRIAL REGISTRATION: The trial was retrospectively registered on 10/10/2023 on ClinicalTrials.gov NCT06076993 .

ABSTRACT

BACKGROUND: South Korea has already become a multicultural society due to immigration, marriage, and employment of foreigners, and the use of medical institutions by foreigners is increasing. In order to establish a therapeutic rapport relationship with foreigners, it is necessary to study multicultural acceptance. This study aimed to examine and identify the factors influencing the degree of multicultural acceptance of Korean nursing students.

METHODS: This study used a cross-sectional descriptive design. Study participants included 147 nursing students at University in Seoul or Gyeonggi-do, South Korea. Data included demographics, multicultural acceptance, cultural empathy, and multicultural attitude. Data were collected from March to June 2021. Data was analyzed using linear regression model in SPSS PC + version 23.0 statistical software program.

RESULTS: The adjusted R-squared representing the explanatory power of the model was 72.5%. The strongest predictor was cultural empathy (β = 0.55, P < 0.001), followed by multicultural attitude (β = 0.26, P = 0.001), residential area where they lived for the past 5 years (β = 0.19, P = 0.001), accessibility to multicultural internet and media (β = 0.17, P = 0.003), whether they have foreign friends (β = 0.16, P = 0.003), and multicultural education experience (β = 0.02, P = 0.002).

CONCLUSION: This study suggests that to improve the degree of multicultural acceptance of Korean nursing students, their cultural empathy and multicultural attitude should be strengthened. Nurses need to pay attention the influencing factors to improve the multicultural acceptance of Korean nursing students.
