Abstract
Objective
There are more than one million children and adolescents living with type 1 diabetes mellitus, and their number is steadily increasing. Diabetes affects oral health through numerous channels, including hyposalivation, immune suppression, and the inflammatory effect of glycation end-products. However, patients with type 1 diabetes must follow a strict sugar free diet that is proven to be carioprotective. Therefore, the aim of this systematic review and meta-analysis is to investigate whether children with type 1 diabetes have a difference in Decayed, Missing, Filled Teeth index (DMFT), salivary function, and periodontal status than children without diabetes, with an emphasis on glycemic control.

Materials and Methods
PubMed, Embase and Cochrane libraries were screened for articles, using predefined search keys without any language or date restrictions. Two independent authors performed the selection procedure, extracted data from the eligible articles, carried out a manual search of the reference lists, and assessed the risk of bias using the Newcastle-Ottawa scale. Meta-analysis was performed in R using the random-effects model. Effect sizes were mean differences; subgroup analysis was performed on glycemic control.

Results
33 studies satisfied the eligibility criteria. 22 studies did not show a significant difference regarding the DMFT index between the diabetes and non-diabetes groups; six studies found that children living with diabetes had higher DMFT scores, compared to five studies that found significantly lower scores. Meta-analysis found no statistically significant differences in plaque, gingival, and calculus indexes, however it found significant differences in pooled DMFT indexes, and salivary flow rate. Subgroup analysis on glycemic control using DMFT values found significant differences in children with good and poor glycemic control with results of 0.26 (CI95%=-0.50; 1.03) and 1.46 (CI95%=0.57; 2.35), respectively.

Conclusions
Children with poor glycemic control face higher risk of developing caries compared to good control and non-diabetes children. Regular dental check-ups and strict control of glycemic levels are highly advised for children living with type 1 diabetes, further emphasizing the importance of cooperation between dentists and diabetologists.

Published: June 2024

Abstract
Background
Mothers usually have the primary role in raising children and developing health-related behaviors. This study aims to evaluate the relationship between dental anxiety and oral hygiene status of mothers and children’s dental anxiety and gingival health.

Methods
The study included 305 children, aged 4–12 years, who came to the dentist for the first time and their mothers. All the demographic and oral hygiene information were collected through a questionnaire. The dental anxiety of the mothers and children was assessed using the Modified Dental Anxiety Scale (MDAS) and Venham Picture Test (VPT), respectively. The oral examination of the mother and children was performed, and their PI, GI, and DMFT scores were recorded.

Results
While the correlation between MDAS and VPT was positive and strong in children aged 8–12, it was positive but weak in the 4–7 age group. A significant relationship was detected between the mother’s PI, GI, DMFT, and the child’s VPT score. According to the mothers’ dental anxiety, there were no statistically significant differences in PI, GI, and dmft values in children aged between 4 to 7. A moderately positive and statistically significant relationship between maternal dental anxiety and children’s DMFT was identified in children aged 8–12.

Conclusions
Children’s dental anxiety was significantly influenced by maternal dental anxiety, post-treatment complications experienced by the mother, and the oral health status of the mother.

Abstract
Background
Chronic pain affects over 100 million Americans, with a disproportionately high number being Veterans. Chronic pain is often difficult to treat and responds variably to medications, with many providing minimal relief or having adverse side effects that preclude use. Cannabidiol (CBD) has emerged as a potential treatment for chronic pain, yet research in this area remains limited, with few studies examining CBD’s analgesic potential. Because Veterans have a high need for improved pain care, we designed a clinical trial to investigate CBD’s effectiveness in managing chronic pain symptoms among Veterans. We aim to determine whether CBD oral solution compared to placebo study medication is associated with greater improvement in the Patient Global Impression of Change (PGIC).

Methods
We designed a randomized, double-blind, placebo-controlled, pragmatic clinical trial with 468 participants. Participants will be randomly assigned in a 1:1 ratio to receive either placebo or a CBD oral solution over a 4-week period. The trial is remote via a smartphone app and by shipping study materials, including study medication, to participants. We will compare the difference in PGIC between the CBD and placebo group after four weeks and impacts on secondary outcomes (e.g., pain severity, pain interference, anxiety, suicide ideation, and sleep disturbance).

Discussion
Once complete, this trial will be among the largest to date investigating the efficacy of CBD for chronic pain. Findings from this clinical trial will contribute to a greater knowledge of CBD’s analgesic potential and guide further research. Given the relative availability of CBD, our findings will help elucidate the potential of an accessible option for helping to manage chronic pain among Veterans.

This protocol is registered at clinicaltrials.gov under study number NCT06213233.
Medical-informed machine learning: integrating prior knowledge into medical decision systems
Authors: Sirocchi Christel , Bogliolo Alessandro , Montagna Sara 
Published: June 2024

Abstract
Background
Clinical medicine offers a promising arena for applying Machine Learning (ML) models. However, despite numerous studies employing ML in medical data analysis, only a fraction have impacted clinical care. This article underscores the importance of utilising ML in medical data analysis, recognising that ML alone may not adequately capture the full complexity of clinical data, thereby advocating for the integration of medical domain knowledge in ML.

Methods
The study conducts a comprehensive review of prior efforts in integrating medical knowledge into ML and maps these integration strategies onto the phases of the ML pipeline, encompassing data pre-processing, feature engineering, model training, and output evaluation. The study further explores the significance and impact of such integration through a case study on diabetes prediction. Here, clinical knowledge, encompassing rules, causal networks, intervals, and formulas, is integrated at each stage of the ML pipeline, resulting in a spectrum of integrated models.

Results
The findings highlight the benefits of integration in terms of accuracy, interpretability, data efficiency, and adherence to clinical guidelines. In several cases, integrated models outperformed purely data-driven approaches, underscoring the potential for domain knowledge to enhance ML models through improved generalisation. In other cases, the integration was instrumental in enhancing model interpretability and ensuring conformity with established clinical guidelines. Notably, knowledge integration also proved effective in maintaining performance under limited data scenarios.

Conclusions
By illustrating various integration strategies through a clinical case study, this work provides guidance to inspire and facilitate future integration efforts. Furthermore, the study identifies the need to refine domain knowledge representation and fine-tune its contribution to the ML model as the two main challenges to integration and aims to stimulate further research in this direction.
The role of Empathy in the relationship between emotional support and caring behavior towards patients among intern nursing students
Authors: Atta Mohamed Hussein Ramadan , Hammad Heba Abdel-Hamid , Elzohairy Nadia Waheed 
Published: June 2024

Abstract
Background
The empathic relationship between nursing students and patients allows them to understand and address caring behavior for patients. Appropriate emotional support equips them to overcome the complexities and difficulties inherent in patient care. This support cultivates resilience and self-awareness, enabling students to manage their emotions effectively and establish meaningful connections and caring with their patients.

Objectives
To investigate the role of empathy in the association between emotional support and caring behavior toward patients among intern nursing students at Alexandria and Damanhur University.

Subjects
The study subjects were 200 intern nursing students in their internship years of 2022–2023, randomly selected from an equal sample size from Alexandria and Damanhur University, Egypt.

Tools
A questionnaire of social information& academics from students, the Toronto Empathy Questionnaire, the Caring Dimension Inventory, and the Multidimensional Scale of Perceived Social Support are used to collect participants’ data.

Results
Empathy was associated with caring behavior and emotional support among nursing students (P < 0.001), and higher levels of empathy indicated increased levels of caring behavior and emotional support. The caring behavior significantly increased when intern nursing students received more emotional support and among those who were not working in private hospitals (p < 0.001,&p = 0.023 respectively). Empathy acts as a mediating role in the relationship between emotional support and caring behavior.

Implications
Implementing strategies to assist interns in navigating challenges and promoting a culture of support can facilitate the cultivation of caring behaviors. Shedding light on the interconnectedness of empathy, emotional support, and caring behavior can inform the design of interventions to strengthen empathy as a pathway to improving patient outcomes.

Conclusion
Empathy is a mediating factor in the relationship between emotional support and caring behavior. This suggests that interventions promoting empathy may serve as a pathway to enhancing caring behavior among nursing students and strategies for improving patient care outcomes by strengthening empathy skills among healthcare professionals.
Dietary choline intake in European and non-european populations: current status and future trends—a narrative review
Authors: Zuk Ewelina , Nikrandt Grzegorz , Chmurzynska Agata 
Published: June 2024

Abstract
Background
Choline is a nutrient necessary for the proper functioning of the body with a multidimensional impact on human health. However, comprehensive studies evaluating the dietary intake of choline are limited. The aim of this narrative review is to analyze current trends in choline intake in European and non-European populations. The secondary aim was to discuss possible future choline trends.

Methods
The search strategy involved a systematic approach to identifying relevant literature that met specific inclusion criteria. Observational studies and randomized clinical trials were searched for in PubMed and Scopus databases from January 2016 to April 2024. This review includes the characteristics of study groups, sample sizes, methods used to assess choline intake and time period, databases used to determine intake, choline intakes, and the main sources of choline in the diet. The review considered all population groups for which information on choline intake was collected.

Results
In most studies performed in Europe after 2015 choline intake did not exceed 80% of the AI standard value. The mean choline intake for adults in different European countries were 310 mg/day, while the highest value was reported for Polish men at 519 mg/day. In non-European countries, mean choline intakes were 293 mg/day and above. The main reported sources of choline in the diet are products of animal origin, mainly eggs and meat. The available data describing the potential intake of these products in the EU in the future predict an increase in egg intake by another 8% compared to 2008–2019 and a decrease in meat intake by about 2 kg per capita from 2018 to 2030.

Conclusions
In the last decade, choline intake among adults has been insufficient, both in Europe and outside it. In each population group, including pregnant women, choline intake has been lower than recommended. Future choline intake may depend on trends in meat and egg consumption, but also on the rapidly growing market of plant-based products. However, the possible changes in the intake of the main sources of choline may lead to either no change or a slight increase in overall choline intake.

Published: June 2024

Abstract
Background
Needle and syringe programs (NSP) are effective harm-reduction strategies against HIV and hepatitis C. Although skin, soft tissue, and vascular infections (SSTVI) are the most common morbidities in people who inject drugs (PWID), the extent to which NSP are clinically and cost-effective in relation to SSTVI in PWID remains unclear. The objective of this study was to model the clinical- and cost-effectiveness of NSP with respect to treatment of SSTVI in PWID.

Methods
We performed a model-based, economic evaluation comparing a scenario with NSP to a scenario without NSP. We developed a microsimulation model to generate two cohorts of 100,000 individuals corresponding to each NSP scenario and estimated quality-adjusted life-years (QALY) and cost (in 2022 Canadian dollars) over a 5-year time horizon (1.5% per annum for costs and outcomes). To assess the clinical effectiveness of NSP, we conducted survival analysis that accounted for the recurrent use of health care services for treating SSTVI and SSTVI mortality in the presence of competing risks.

Results
The incremental cost-effectiveness ratio associated with NSP was $70,278 per QALY, with incremental cost and QALY gains corresponding to $1207 and 0.017 QALY, respectively. Under the scenario with NSP, there were 788 fewer SSTVI deaths per 100,000 PWID, corresponding to 24% lower relative hazard of mortality from SSTVI (hazard ratio [HR] = 0.76; 95% confidence interval [CI] = 0.72–0.80). Health service utilization over the 5-year period remained lower under the scenario with NSP (outpatient: 66,511 vs. 86,879; emergency department: 9920 vs. 12,922; inpatient: 4282 vs. 5596). Relatedly, having NSP was associated with a modest reduction in the relative hazard of recurrent outpatient visits (HR = 0.96; 95% CI = 0.95–0.97) for purulent SSTVI as well as outpatient (HR = 0.88; 95% CI = 0.87–0.88) and emergency department visits (HR = 0.98; 95% CI = 0.97–0.99) for non-purulent SSTVI.

Conclusions
Both the individuals and the healthcare system benefit from NSP through lower risk of SSTVI mortality and prevention of recurrent outpatient and emergency department visits to treat SSTVI. The microsimulation framework provides insights into clinical and economic implications of NSP, which can serve as valuable evidence that can aid decision-making in expansion of NSP services.
piRNA associates with immune diseases
Authors: Jiang Mingye , Hong Xiaoning , Gao Yunfei , Kho Alvin T. , Tantisira Kelan G. , Li Jiang 
Published: June 2024

AbstractPIWI-interacting RNA (piRNA) is the most abundant small non-coding RNA in animal cells, typically 26–31 nucleotides in length and it binds with PIWI proteins, a subfamily of Argonaute proteins. Initially discovered in germ cells, piRNA is well known for its role in silencing transposons and maintaining genome integrity. However, piRNA is also present in somatic cells as well as in extracellular vesicles and exosomes. While piRNA has been extensively studied in various diseases, particular cancer, its function in immune diseases remains unclear. In this review, we summarize current research on piRNA in immune diseases. We first introduce the basic characteristics, biogenesis and functions of piRNA. Then, we review the association of piRNA with different types of immune diseases, including autoimmune diseases, immunodeficiency diseases, infectious diseases, and other immune-related diseases. piRNA is considered a promising biomarker for diseases, highlighting the need for further research into its potential mechanisms in disease pathogenesis.

Published: June 2024

Abstract
Background
Maintaining static balance is relevant and common in everyday life and it depends on a correct intersegmental coordination. A change or reduction in postural capacity has been linked to increased risk of falls. People with Parkinson’s disease (pwPD) experience motor symptoms affecting the maintenance of a stable posture. The aim of the study is to understand the intersegmental changes in postural sway and to apply a trend change analysis to uncover different movement strategies between pwPD and healthy adults.

Methods
In total, 61 healthy participants, 40 young (YO), 21 old participants (OP), and 29 pwPD (13 during medication off, PDoff; 23 during medication on, PDon) were included. Participants stood quietly for 10 s as part of the Short Physical Performance Battery. Inertial measurement units (IMU) at the head, sternum, and lumbar region were used to extract postural parameters and a trend change analysis (TCA) was performed to compare between groups.

Objective
This study aims to explore the potential application of TCA for the assessment of postural stability using IMUs, and secondly, to employ this analysis within the context of neurological diseases, specifically Parkinson’s disease.

Results
Comparison of sensors locations revealed significant differences between head, sternum and pelvis for almost all parameters and cohorts. When comparing PDon and PDoff, the TCA revealed differences that were not seen by any other parameter.

Conclusions
While all parameters could differentiate between sensor locations, no group differences could be uncovered except for the TCA that allowed to distinguish between the PD on/off. The potential of the TCA to assess disease progression, response to treatment or even the prodromal PD phase should be explored in future studies.

Trial registration
The research procedure was approved by the ethical committee of the Medical Faculty of Kiel University (D438/18). The study is registered in the German Clinical Trials Register (DRKS00022998).

Published: June 2024

Abstract
Background
There is limited data on the 2-year outcomes of transapical transcatheter edge-to-edge repair (TA-TEER) using the ValveClamp in patients with severe primary mitral regurgitation (MR) and its impact on myocardial deformation.

Methods
From July 2018 to March 2021, 53 patients with symptomatic severe primary MR underwent TA-TEER were enrolled. The endpoint was the composite of all-cause mortality, recurrent 3 + or 4 + MR, or need for mitral surgery.

Results
Among the 53 patients who had successfully ValveClamp implantation, 8(15.1%) reached the composite endpoint. Significant improvement in left ventricular (LV) end-diastolic volume, pulmonary artery systolic pressure, NYHA functional class, and MR severity were observed (P < 0.05 for all). Univariate Cox’s regression analysis revealed that LV end-diastolic volume index, LV end-systolic volume index, left atrial volume index, and pulmonary artery systolic pressure were associated with adverse events (P < 0.05 for all). On multivariate Cox regression analysis, left atrial volume index was independently associated with the endpoint (hazard ratio, 1.049; 95% CI, 1.009–1.091; P < 0.001) after adjustment for above echocardiographic parameters. LV global longitudinal strain and apical longitudinal strain in global and regional segments decreased at 30 days, but showed a recovery at 2 years with no significant difference compared to the baseline.

Conclusion
TA-TEER using the ValveClamp presented favorable safety and efficacy at 2-year. Myocardial deformation impairment was observed at 30 days post-procedure, but did not persist at 2 years.
