Published: July 2024

Abstract
Background
Due to the exclusion of pregnant and lactating people from most clinical trials, there is an incomplete understanding of the risks and benefits of medication use in these populations and therapeutic decision-making is often conducted without adequate evidence. To change this paradigm, it is imperative to understand the perspectives of pregnant and lactating individuals concerning their participation in clinical trials.

Objectives
To describe attitudes, perceptions, barriers, and preferences of pregnant and postpartum people in the United States (US) regarding participation in clinical trials and to identify factors influencing participation.

Methods
In November 2022, individuals aged ≥ 18 residing in the US who self-identified as pregnant or pregnant within the last 12 months were invited to complete an online survey about their perspectives regarding clinical trial participation. The survey included questions about demographic characteristics, health history, behaviors, and willingness to participate in clinical trials while pregnant and/or lactating. Multivariable logistic regression models were fit to identify predictors of clinical trial participation.

Results
Among the 654 respondents, 34.8% and 40.9% reported being likely or extremely likely to participate in a clinical trial for a new medication while pregnant or lactating, respectively; and 24.5% and 41.7% for a new vaccine while pregnant or lactating, respectively. Higher educational attainment (≥ Bachelor’s degree) was associated with greater likelihood of clinical trial participation in pregnancy (odds ratio (OR) = 1.50, 95% Confidence Interval (CI): 1.01, 2.25 for medications; OR = 2.00, 95% CI: 1.28, 3.12 for vaccines). Chronic medical conditions were associated with a greater likelihood of participation in clinical trials for vaccines during lactation (OR = 1.59, 95% CI: 1.07, 2.36). The most cited motivator for participation in a clinical trial while pregnant or lactating was anticipated personal medical benefit (85.8% and 75.6%, respectively), while the primary deterrent was possible risk to the fetus or baby (97.9% and 97.2%, respectively).

Conclusions
Willingness of a US sample to participate in clinical trials while pregnant or lactating varied by demographics and health status, with safety to the fetus being a nearly universal concern. These findings have implications for enhancing inclusion of pregnant and lactating people in clinical research and developing effective and equitable recruitment strategies.

Abstract
Background
Sex trafficking victims often have touchpoints with salons for waxing, styling, and other body modification services required by traffickers. Recently, some states have administered laws requiring salon professionals to receive intimate partner violence (IPV)-related training, with even fewer states mandating training on identifying sex trafficking. This study aimed to understand how salon professionals have witnessed evidence of violence, including IPV and sex trafficking, in the workplace and to explore the differences in their approach to each type of victim.

Methods
In-depth interviews were conducted with salon professionals (N = 10) and law enforcement professionals/policymakers (N = 5). Content and thematic analysis techniques were used.

Results
Salon professionals typically identified potential violence through signs such as bruises, odd behavior, and client disclosures, prompting them to engage in cautious conversations. Yet, few were trained to identify and intervene. Often, they responded to suspected violence by talking with the client, sharing concerns with salon leadership, directly intervening on the client’s behalf, or contacting the police. Law enforcement and salon professionals had suggestions about improving salon professionals’ recognition of and response to violence, including training on victim-focused resources, creating a safe environment, and building relationships with law enforcement. They also suggested strengthening community partnerships to increase resource advocacy and reporting.

Conclusions
One-on-one salon services may provide a unique opportunity to intervene and identify victims of violence, especially when empowered through additional training and collaborative partnerships with community-oriented policing initiates. Implementing training and community-based initiatives could aid salon professionals in gaining greater confidence in knowing what to do when serving a client who is a victim of IPV or sex trafficking.
MALAT1 predicts the prognosis of severe community-acquired pneumonia in pediatric patients
Authors: Yang Mei , Xuan Aili , Liu Qian , Zhu Guoji 
Published: July 2024

Abstract
Background
To evaluate the role of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in the prognosis of severe community-acquired pneumonia (CAP) in children.

Methods
According to the median MALAT1 value of 3.2 at baseline, 93 pediatric patients with severe CAP were divided into low (n = 46, median MALAT1 level = 1.9) or high (n = 47, median MALAT1 level = 4.5) MALAT1 groups. Another 93 age-, gender-, and body mass index (BMI)-matched healthy individuals were included in the control group using the propensity-score matching (PSM) method. A multivariate Cox proportional hazards model was used to explore the association of MALAT1 level with the 28-day mortality after controlling for potential confounding factors.

Results
The MALAT1 expressions were significantly higher in the patients with severe CAP compared with those in the healthy controls (3.2 vs. 0.9, P < 0.01). The receiver operating characteristic (ROC) analysis showed that the area under the curve (AUC) was 0.927 when the cut-off value of MALAT1 was 1.5. Moreover, the MALAT1 expressions were substantially lower in survivals than non-survivals (3.8 vs. 2.6, P < 0.01), and the multivariate Cox regression analysis indicated a positive association between MALAT1 levels and mortality risk (HR = 3.32; 95% CI: 1.05–10.47; P = 0.04).

Conclusion
MALAT1 might be a promising marker for predicting the prognosis of severe CAP in pediatric patients.

Published: July 2024

Abstract
Objective
Acute acromioclavicular (AC) joint dislocation is a common orthopedic injury that can significantly impair shoulder function and reduce quality of life. Effective treatment methods are essential to restore function and alleviate pain. To investigate the short-term clinical efficacy of the minimally invasive closed-loop double endobutton fixation assisted by orthopaedic surgery robot positioning system (TiRobot) in the treatment of AC joint dislocation, and to evaluate its feasibility and safety.

Methods
The clinical data of 19 patients with AC joint dislocation who underwent treatment with closed-loop double Endobutton fixation assisted by TiRobot between May 2020 and December 2022 were retrospectively analyzed. Visual Analog Scale (VAS) pain scores, the Constant Murley Score (CMS), and shoulder abduction range of motion were assessed and compared preoperatively and at the last follow-up. Computed tomography (CT) parameters of the acromioclavicular joint, including acromioclavicular distance (ACD), the distance between the upper and lower Endobutton (DED), the horizontal distance between the anterior edge of the distal clavicle and the anterior edge of the acromion (DACC), the diameter of the clavicular tunnel (DCT), and coracoid tunnel diameter (DC), were compared at 2 days, and 1 month after surgery, as well as at the last follow-up, along with the evaluation of intraoperative and postoperative complications.

Results
The postoperative VAS, CMS, and shoulder-abduction range of motion were significantly improved compared with the preoperative (all, P<0.05). The statistical analysis showed no significant difference in the CT image parameters of the acromioclavicular joint at 2 days and 1 month after surgery(all, P>0.05). Comparisons of DCT and DC revealed statistically significant differences between the last follow-up and 1 month after surgery (P<0.05), and no statistically significant difference was found in ACD, DED, and DACC(all, P>0.05). There were no complications such as infection or vascular or neurological damage, no cases of rostral or clavicle fractures, loss of reduction, heterotopic ossification, shoulder stiffness, and no loosening or breaking of internal fixations.

Conclusion
Closed-loop double endobutton internal fixation assisted by TiRobot is an ideal method for the treatment of acute acromioclavicular (AC) joint dislocation. This method has the advantages of relatively simple operation, more accurate localization of bone tunnel during operation, less surgical trauma, and good recovery of shoulder function.
Association between flavonoids intake and dental caries in children and adolescents: a cross-sectional study from the NHANES database
Authors: Fan Jianing , Liu Siqi , Zhang Qian , Qiao Li , Chu Qingsong 
Published: July 2024

Abstract
Background
Worldwide, dental caries is a bacterial biofilm-mediated condition with a high morbidity in children and adolescents. Flavonoids are a class of active natural products with antibacterial and anti-inflammatory effect. In vivo and in vitro studies have shown that they can promote tooth mineralization and reduce inflammation. However, the association of flavonoids intake and dental caries in children and adolescents remain unclear.

Aim
This study was to evaluated the association of flavonoid and its subclass intake and dental caries in children and adolescents.

Methods
Data of participants aged 2-17 years were extracted from the National Health and Nutrition Examination Survey (NHANES) database (2017-2018). Dental caries was measured via the decayed or filled surfaces in primary teeth or permanent teeth (dfs/DFS) index. The weighted univariable and multivariable logistic regression models were utilized to explore the association of flavonoids intake with dental caries in children and adolescents, with odds ratios (ORs) with 95% confidence intervals (CIs). Subgroups analyses based on age, and overweight/obesity were further assessed the association. Subgroup analysis were further performed to explore whether the association between subclasses of anthocyanidins and catechins with dental caries was robust stratified by age and individual with overweight/obesity.

Results
Among totally 1,818 children and adolescents, 786 (43.2%) had dental caries. High intake of anthocyanidins (OR=0.69, 95%CI: 0.52-0.92) and catechins (OR=0.64, 95%CI: 0.44-0.92) were associated with lower odds of dental caries. Similar results were discovered in individuals aged ≥6 years (anthocyanidins, OR=0.62, 95%CI: 0.43-0.90; catechins, OR=0.62, 95%CI: 0.40-0.96), and without overweight/obesity (anthocyanidins, OR=0.58, 95%CI: 0.37-0.90; catechins, OR=0.51, 95%CI: 0.31-0.84). Further investigation found that high intake of cyanidin, petunidin, malvidin, peonidin, (+)-Catechin, (-)-Epigallocatechin, and (-)-epicatechin were associated with lower odds of dental caries in children and adolescents.

Conclusion
High intake of anthocyanidins and catechins were associated with lower odds of dental caries in children and adolescents and are a promising intervention to be further explored in children and adolescents.

Published: July 2024

Abstract
Objective
To develop a novel mandibular advancement device (MAD) with high comfort, good compliance, and bidirectional fine-tuning capability for patients with obstructive sleep apnea hypopnea syndrome (OSAHS), and to evaluate the therapeutic efficacy of the new MAD.

Methods
The MAD, featuring upper and lower dental splints with a fine-tuning mechanism for mandibular adjustment, incorporates improved design elements such as partial dental coverage, shortened baffles, and memory resin lining. The novel MAD was used to treat 30 OSAHS patients in the study, comparing pre- and post-treatment scores on the Epworth Sleepiness Scale (ESS), the Apnea-Hypopnea Index (AHI), and the lowest oxygen saturation (LSO2).

Results
The novel MAD reduced size and side effects, enhancing comfort. All patients complied well, using it for an average of 95% over 30 days and ≥ 5 h nightly. After treatment, significant improvements were observed in ESS, AHI, and LSO2 (P < 0.05).

Conclusions
This novel bidirectional adjustable MAD provides high comfort and compliance, improving treatment precision. It is an effective choice for mild to moderate OSAHS patients and an alternative for those intolerant to CPAP or averse to surgery.
Influence of various fabrication techniques and porcelain firing on the accuracy of metal-ceramic crowns
Authors: Usta Kutlu İlknur , Hayran Yeliz 
Published: July 2024

Abstract
Background
The fit of a metal-ceramic restoration is essential to its long-term durability. Regarding marginal and internal fit, there is not enough information about the technologies used in the production of metal-ceramic restorations. The aim of this in vitro study is to compare, both before and after porcelain firing, the marginal, axial, axio-occlusal, and occlusal fit of metal-ceramic restorations manufactured using casting, additive or subtractive computer-aided design, and computer-aided manufacturing techniques (CAD/CAM).

Methods
CAD/CAM were used to create 50 prepared maxillary first molar-shaped Co-Cr die models, which were randomly divided into 5 groups (n = 10). Cobalt-chrome copings were produced by casting (C), hard metal milling (HM), soft metal milling (SM), selective laser melting (SLM), and selective laser sintering (SLS) techniques. Before and after porcelain firing, discrepancies of the copings were measured using the silicone replica technique. The data obtained by measurements with a stereomicroscope at x80 magnification were analyzed statistically in the SPSS program. The ROBUST three-way analysis of variance (ANOVA) method was used to compare the discrepancy values.

Results
There were statistically significant differences among fabrication methods (P < .001). The HM method showed the highest discrepancy (90.1 μm), and the C (63 μm) method showed the lowest discrepancy in terms of the die model- crown fit. The C, SLS, and SM methods (63 μm; 61.6 μm; 67.7 μm) were statistically similar (P > .001). The highest discrepancy was observed on the occlusal area (87.1 μm), and the lowest discrepancy was observed on the axial area (47.7 μm) of the coping. Porcelain firing had a decrease in the discrepancy values (P = .001).

Conclusion
All CAD/CAM techniques are appropriate for clinical use; selective laser sintering and soft milling can be the more recommended methods for the compatibility of metal-porcelain restorations, as they have lower discrepancy values than the SLM and HM methods.

Published: July 2024

Abstract
Background
During the COVID-19 pandemic, the way in which end-of-life care was provided, underwent a lot of changes and therefor different domains of end-of-life care were impacted. The aim of this study is to describe whether health care providers considered end-of-life care (in medical, nursing, psychosocial and spiritual care) limited by the pandemic through the first 18 months of the COVID-19 pandemic, and examine associations with COVID-19 related circumstances of care (e.g. visit restrictions) and health care providers’ characteristics.

Methods
A longitudinal survey study among healthcare providers from different healthcare settings who provided end-of-life care during the pandemic’s first 18 months. Data of four time periods were analyzed using descriptive statistics and Generalized Estimating Equation.

Results
Of the respondents (n = 302) the majority had a nursing background (71.8%) and most worked in a hospital (30.3%). Especially in the first wave end-of-life care in all aspects was limited according to a substantial part of health care providers (between 29.7 and 57.7%). Psychosocial and spiritual care were more limited than medical and nursing care during all time periods. Care being limited according to health care providers was associated with visit restrictions, shortness of personal protective equipment or restrictions in caring for the deceased and decreased over time.

Conclusion
The COVID-19 pandemic impacted different aspects of end-of-life care throughout the pandemic’s first 18 months. Over the course of the pandemic health care providers seemed to have invented ways to adjust their work in order to minimize the effect of limiting measures. More involvement of health care providers in decision-making may improve the prioritization of measures to deal with crisis situations in care. These reflections highlight priorities during crises and the role healthcare providers could play in maintaining good end-of-life care. This remains relevant in new health crises, where care may differ from what is considered good quality of care.

Published: July 2024

Abstract
Background
Moringa oleifera is a highly nutritious plant widely used in traditional medicine.

Results
The aroma constituents present in the fresh flowers of M. oleifera versus the hydrodistilled oil and hexane extract were studied using GC-MS. Aldehydes were the major class detected in the fresh flowers (64.75%) with E-2-hexenal being the predominant component constituting > 50%. Alkane hydrocarbons, monoterpenes, and aldehydes constituted > 50% of the hydrodistilled oil, while alkane hydrocarbons exclusively constitute up to 65.48% of the hexane extract with heptacosane being the major component (46.2%). The cytotoxicity of the hexane extract was assessed on RAW 264.7 macrophages using the MTT assay which revealed no significant cytotoxicity at concentrations of 1 µg/mL and displayed IC50 value at 398.53 µg/mL as compared to celecoxib (anti-inflammatory drug) with IC50 value at 274.55 µg/ml. The hexane extract of Moringa flowers displayed good anti-inflammatory activity through suppression of NO, IL-6, and TNF-α in lipopolysaccharide-induced RAW 264.7 macrophages. The total phenolic and flavonoid content in the hexane extract was found to be 12.51 ± 0.28 mg GAE/g extract and 0.16 ± 0.01 mg RuE/g extract, respectively. It displayed moderate antioxidant activity as indicated by the in vitro DPPH, ABTS, CUPRAC, FRAP, and phosphomolybdenum (PBA) assays. No metal chelating properties were observed for the extract. The enzyme inhibitory potential of the hexane extract was evaluated on acetyl- and butyrylcholinesterases (for neuroprotective assessment), α-amylase and α-glucosidase (for antihyperglycemic assessment), and tyrosinase (for dermoprotective assessment) revealing promising results on cholinesterases, tyrosinase, and α-glucosidase.

Conclusion
Our findings suggested that M. oleifera leaves can be considered as a multidirectional ingredient for preparing functional applications.

Published: July 2024

Abstract
Background
Allied health assistants (AHAs) support allied health professionals (AHPs) to meet workforce demands in modern healthcare systems. In an Australian context historically, AHAs have been sub-optimally utilised. Prior research has identified that AHAs and AHPs working in health, disability and aged care sectors, and the Vocational Education and Training (VET) industry, may benefit from access to resources to support the optimisation of the AHA workforce. As a part of a Victorian department of health funded project, several resources were developed in line with workforce recommendations for use in each of the above sectors. Recommendations and resources covered the broad areas of pre-employment training, workforce planning and governance, consumer-centred therapy and supports, recruitment and induction and workplace training and development. This study aimed to evaluate the engagement with these newly designed resources to support optimisation of AHAs in the Victorian context.

Methods
Semi-structured interviews were conducted to evaluate engagement with resources, from the perspective of AHAs, AHPs and allied health leaders (AHLs) in the health, aged care or disability sectors, and educators and managers of allied health assistance training. Thematic analysis was conducted using team-based framework analysis.

Results
Thematic framework analysis of the interview data identified four themes; Why participants accessed the resources; How participants engaged with the resources; What (if any) changes in practice occurred as a result of engaging with the resources in a participant’s local context, How did participants envision the resources being utilised for AHA workforce optimisation in the future. Responses were mapped to the AHA workforce career pathway at the career preparation, career development and career trajectory tiers.

Conclusions
Appetite for AHA workforce development and optimal utilisation is evident across Victoria, Australia. Readily accessible resources that inform AHA role and scope of practice, delegation practice, or improve the ability for an AHA to state their own development needs, were identified as useful by participants. The potential for these resources to assist in the optimal utilisation and development of AHA workforces across the career continuum differs according to the role, sector and geographical location of the resource user. Further study is needed to investigate the transferability of these resources to national and global contexts.
