Published: December 2023

Abstract
Background
The deer antler, a remarkable mammalian appendage, has a growth rate surpassing that of any other known osseous organ. Emerging evidence indicates that circRNA and MAPK1 play critical roles in chondrocytes. Thus, exploration of their functions in antler chondrocytes will help us to understand the mechanism regulating the rapid antler growth.

Methods
qRT-PCR, western blot, and immunohistochemistry were used to assess the expression of mRNAs and proteins. CCK-8, EdU, Cell migration, ALP activity detection, and ALP staining examined the effects of MAPK1 in antler chondrocytes. FISH, RIP, and luciferase assays were performed to evaluate the interactions among circRNA3634/MAPK1 and miR-124486-5. RIP and RAP assays proved the binding interaction between circRNA3634 and RBPs. Me-RIP was used to determine the m6A methylation modification of circRNA3634.

Results
This study revealed high MAPK1 expression in antler cartilage tissue. Overexpression of MAPK1 promoted the proliferation, migration, and differentiation of antler chondrocytes and increased the expression of MAPK3, RAF1, MEK1, RUNX2, and SOX9. The silencing of MAPK1 had the opposite effect. CircRNA3634 was found to act as a molecular sponge for miR-124486-5, leading to increased MAPK1 expression and enhanced proliferation and migration of antler chondrocytes through competitive miR-124486-5 binding. We discovered that METTL3 mediates m6A modification near the splicing site of circRNA3634 and is involved in the proliferation and differentiation of antler chondrocytes. The m6A reader YTHDC1 facilitated the nuclear export of circRNA3634 in an m6A-dependent manner. Our results indicate that m6A-modified circRNA3634 promotes the proliferation of antler chondrocytes by targeting MAPK1 and show that the nuclear export of circRNA3634 is related to the expression of YTHDC1, suggesting that circRNA3634 could represent a critical regeneration marker for the antler.

Conclusions
Our results revealed a novel m6A-modified circRNA3634 promoted the proliferation and differentiation of antler chondrocytes by regulating MAPK1. The nuclear export of circRNA3634 was related to the expression of YTHDC1.

Published: December 2023

Abstract
Background
This study explores the age, growth, and energy storage of Triplophysa rosa, a troglobitic cavefish. A total of 102 wild T. rosa specimens were collected in Wulong County, Chongqing, China, between 2018 and 2022, with otoliths used for age determination.

Results
The earliest mature individuals were determined to be 4.8 years old, while the maximum ages for females and males were estimated at 15.8 years and 12.2 years, respectively. The length (L, cm)-weight (W, g) relationship was found to be the same for both sexes, following the eq. W = 0.0046 L3.03. Von Bertalanffy growth models were applied to the total length-at-age data, resulting in an asymptotic length of 23.4 cm and a K-parameter of 0.060 year−1. The body content of protein, ash, and glycogen did not show a significant correlation with the total length of T. rosa. However, both lipid and energy content exhibited a significant increase with total length. The lipid content ranged from 40.5 to 167.1 mg g−1, while the energy content ranged from 4.50 to 11.39 kJ g−1, indicating high storage features of T. rosa.

Conclusions
The results affirm that T. rosa exhibits life traits conducive to its population dynamics in cave conditions, characterized by slow growth, small size, and high lipid energy storage.

Authors: Seo Myong-Won , Eum Youngseob , Jung Hyun Chul 
Published: December 2023

Abstract
Purpose
Physical activity (PA) is a modifiable factor in preventing/treating cardiometabolic disease. However, no studies have yet compared specific moderate-to-vigorous PA (MVPA) domains with the risk of metabolic syndrome (MetS) in detail. Here, the present study was conducted to examine the impact of different MVPA domains (leisure-time PA (LTPA) vs. occupational PA (OPA) vs. total MVPA) on the risk of MetS in Korean adults. Materials and methods: Data from the 2014 to 2021 Korea National Health and Nutrition Examination Survey were analyzed (N = 31,558). MetS was defined according to the criteria by revised NCEP/ATP-III. The domain-specific MVPA was assessed using the K-GPAQ. The LTPA and OPA status were classified into four categories: (1) 0 min/week, (2) 1 to 149 min/week, (3) 150 to 299 min/week, and 4) ≥ 300 min/week. In addition, the present study calculated total MVPA as a sum of OPA and LTPA and further classified it into six groups; (1) 0 min/week, (2) 1 to 149 min/week, (3) 150 to 299 min/week, (4) 300 to 449 min/week, (5) 450 to 599 min/week, 6) ≥ 600 min/week. Results: The ≥ 300 min/week and the 150 to 299 min/week of LTPA showed better outcomes in cardiometabolic disease risk factors and surrogate markers of insulin resistance compared with the 0 min/week of LTPA regardless of adiposity status. Risk of MetS in ≥ 300 min/week of LTPA was lower than in 0 min/week, 1 to 149 min/week, and 150 to 299. In addition, LTPA was significantly associated with a risk of the MetS in a curvilinear dose-response curve, however, no significant effects of a non-linear relationship between OPA and risk of the MetS. Conclusions: Our findings showed that LTPA was associated with a risk of MetS with a dose-response curve, whereas no significant non-linear effects were found between OPA and the risk of MetS. Therefore, the MVPA domain is an independent factor of the risk of MetS.
Investigation of grief and posttraumatic growth related to patient loss in pediatric intensive care nurses: a cross-sectional study
Authors: Turgut Meral , Yıldız Hatice 
Published: December 2023

Abstract
Background and aim
Pediatric Intensive Care Units (PICUs) are clinical settings where patient loss is frequently experienced. A sense of professional grief and posttraumatic growth in nurses who have experienced patient loss has a significant impact on psychological and physical health, work satisfaction, turnover rates, as well as on personal and professional relations, and employee loyalty. The aim of this study was to investigate grief and posttraumatic growth in PICU nurses and to examine related factors.

Methods
The study is of cross-sectional design and was conducted with 200 nurses who were working in 87 PICU’s around Turkey during the period March 30 - June 30, 2021. Data were collected with a Descriptive Information Form, the Texas Revised Inventory of Grief (TRIG), the Posttraumatic Growth Inventory (PTGI), and an open-ended question asking for suggestions as to how nurses can cope with loss. Online questionnaires were used in the data collection. Descriptive statistics, the student t-test, one-way analysis of variance, and post-hoc tests were employed in the analysis of the data.

Results
The nurses’ mean scores were 49.425 ± 10.868 on TRIG and 61.450 ± 24.934 on PTGI. A negative weak correlation was found between the intensity of the nurses’ grief and their posttraumatic growth (r = 0.144, p = 0.041). Receiving training on dealing with a patient’s terminal stage (t=-2.688, p = 0.001), feeling comfortable about providing the patient’s care (t = 2.624, p = 0.009) and providing the family with emotional support during patient care (t = 1.979, p = 0.049), and the presence of supporting health professionals reduced levels of grief (t = 2.797, p = 0.000). Being a woman (t = 3.299, p = 0.001), willingness to work in the unit (t=-3.219, p = 0.002), and being given enough time to accept the loss (t = 3.986, p = 0.000) were correlated with higher levels of posttraumatic growth. The nurses most commonly wanted more time allotted to recuperate after a loss (n = 35) and professional support (n = 22).

Conclusions
Nurses experience a moderate sense of grief after a patient’s loss. As levels of grief decrease, posttraumatic growth increases. Healthcare administrators and future researchers can benefit from these findings when planning supportive interventions to help nurses cope with their feelings of grief and achieve posttraumatic growth.

Strengths and limitations
A limitation of the study is that it was conducted only with nurses who were Association members.
Are physicians creating a barrier to pre-conception care access? A qualitative study exploring patients’ experiences and perspectives around pre-conception care
Authors: AlWatban Lemmese , Alamer Ebtihal 
Published: December 2023

Abstract
Background
The pre-conception period is an unmissable opportunity to introduce preventive measures before pregnancy to improve maternal and fetal outcomes. Despite the global pre-conception initiatives and the 2030 Saudi national vision to promote maternal, fetal health and safety, various barriers still exist. This study focuses on exploring pre-conception care extensively from the patients’ perspectives and their experience in accessing this type of care in the primary care setting.

Methods
A qualitative study using interpretive thematic analysis was used to explore patients’ perspectives, and experiences in accessing pre-conception care in the city of Riyadh from January 2019 to January 2020. A semi-structured interview guide and field notes were used to collect data. A step wise interpretive and iterative process was used for data analysis and thematic extraction. Theme saturation was achieved by the eleventh interview.

Results
The participants’ perspectives were influenced by their cultural beliefs, understanding of pre-conception, and their prevised barriers to approaching physicians. Three main themes emerged: A) Acceptance of pre-conception care; was heavily influenced by how they understood and defined per-conception care. B) Pre-conception health seeking behavior; demonstrated a clear disconnect between the patient and the physician. C) Expectation from health services; to raise awareness about pre-conception care and push physicians to initiate the conversation with their patients.

Conclusions
An appreciable gap in the patient-physician relationship was revealed as a source of inconsistency in accessing pre-conception care. Physicians are encouraged to take the first step in demonstrating to their patients both the importance of pre-conception care and their intent to offer respectful, empathetic, and culturally appropriate care.

Published: December 2023

Abstract
Background
Individuals seen in Primary Care with behavioral health concerns who decline behavioral health treatment may benefit from the support of peers (consumers in recovery from behavioral health concerns employed to support other consumers). Whole Health STEPS is a new intervention for Veterans in Primary Care with behavioral health concerns which combines essential elements of peers’ role and the Whole Health model using a stepped-care design. We incorporated stakeholder feedback in the Whole Health STEPS design to improve fit with Veterans, peers, and primary care settings.

Methods
We conducted semi-structured qualitative interviews with VA staff using questions derived from the Consolidated Framework for Implementation Research (CFIR). Participants were recruited via a maximum variation strategy across a national sample and interviewed between January 2021-April 2021. The analytic design was a rapid qualitative analysis. Interviews addressed design decisions and potential barriers and facilitators to future implementation. Then, we made adaptations to Whole Health STEPS and catalogued changes using the Framework for Adaptations and Modifications-Enhanced (FRAME). A VA peer conducted the interviews, participated in analyses, assisted with design modifications, and co-wrote this paper.

Results
Sixteen staff members from 9 VA primary care peer programs participated (8 peers and 8 supervisors/administrators). Feedback themes included: capitalizing on peer skills (e.g., navigation), ensuring patient-centered and flexible design, and making it easy and efficient (e.g., reducing session length). Understanding the structure of primary care peers’ roles and their interactions with other programs helped us identify role conflicts (e.g., overlap with Whole Health Coaches and Health Behavior Coordinators), which led to design modifications to carve out a unique role for Whole Health STEPS. Staff also made recommendations about marketing materials and training tools to support Whole Health STEPS roll out.

Conclusions
Feedback from frontline staff, including peers, in the design process was crucial to identifying essential modifications that would not have been possible after initial trials without re-evaluating efficacy due to the extent of the changes. Whole Health STEPS was adapted to fit within a range of program structures, emphasize peers’ unique contributions, and streamline delivery. Lessons learned can be applied to other interventions.
Exosomal miR-182 derived from bone marrow mesenchymal stem cells drives carfilzomib resistance of multiple myeloma cells by targeting SOX6
Authors: Long Shifeng , Long Shengping , He Honglei , Luo Liang , Liu Mei , Ding Ting 
Published: December 2023

Abstract
Background
Multiple myeloma (MM) is a common hematological malignancy. Drug resistance remains to be a major clinical challenge in MM therapy. In this study, we aim to investigate the functional roles of bone marrow mesenchymal stem cells (BMSC)-derived exosomal miR-182 on the carfilzomib resistance of MM and its underlying mechanism.

Methods
qRT-PCR and Western blot methods were utilized to confirm the gene or protein expressions. CCK-8 and transwell assays were performed to measure the capabilities of proliferation, migration, and invasion. The molecular interactions were validated through ChIP and Dual luciferase assay.

Results
Our findings indicated that miR-182 expression was upregulated in serum, BMSCs and BMSC-derived exosomes from MM patients. Hypoxia-inducible factor-1α (HIF-1α), a key transcriptional factor in tumor microenvironment, could boost miR-182 expression by directly binding to its promoter, thus favoring exosomal secretion. Moreover, exosomal miR-182 from BMSCs could be transferred to MM cells and was able to promote malignant proliferation, metastasis, and invasion, as well as decrease the sensitivity of MM cells against carfilzomib. Additionally, SOX6 was identified as a downstream target of miR-182 in MM cells, and its expression was negatively regulated by miR-182. Rescue experiments proved that loss of SOX6 in MM cells dramatically reversed the promoting roles of BMSC-secreted exosomal miR-182 on proliferation, metastasis, and carfilzomib resistance in MM cells.

Conclusion
Collectively, our findings indicated that exosomal miR-182 derived from BMSCs contributed to the metastasis and carfilzomib resistance of MM cells by targeting SOX6. This study sheds light on the pathogenesis of the BMSC-derived exosome containing miR-182 in the malignant behaviors of MM cells and carfzomib resistance.
ACTN1 promotes HNSCC tumorigenesis and cisplatin resistance by enhancing MYH9-dependent degradation of GSK-3β and integrin β1-mediated phosphorylation of FAK
Authors: Cui Li , Lu Ye , Zheng Jiarong , Guo Bing , Zhao Xinyuan 
Published: December 2023

Abstract
Background
Head and neck squamous cell carcinoma (HNSCC) is one of the most common malignant tumors globally. Understanding the molecular basis of tumor progression and drug resistance can offer innovative strategies to enhance clinical outcomes for HNSCC patients.

Methods
The cytoskeletal remodeling genes associated with cisplatin resistance were screened using a PCR array. The role of alpha-actinin 1 (ACTN1) in modulating cisplatin resistance and tumorigenesis in HNSCC was evaluated both in vitro and in vivo. Co-immunoprecipitation (Co-IP), IP-mass spectrometry (MS), western blotting, dual-luciferase assay, and bioinformatics analysis were performed to elucidate the underlying mechanisms involved.

Results
Our study identifies ACTN1 as a crucial contributor to cisplatin resistance and tumorigenesis in HNSCC, as evidenced across cellular, animal, and patient-derived xenograft models. From a clinical perspective, overexpression of ACTN1 significantly correlates with a suboptimal response to neoadjuvant chemotherapy and reduced overall survival in HNSCC patients. Mechanistically, ACTN1 predominantly activates β-catenin-mediated signaling by promoting the interaction between myosin heavy chain 9 (MYH9) and GSK-3β, leading to the ubiquitin-dependent degradation of GSK-3β. ACTN1 also interacts with integrin β1, subsequently activating the FAK/PI3K/AKT pathway, providing an additional avenue for the activation of β-catenin signaling. Our study also unveils that the β-catenin/c-Myc axis transcriptionally regulates ACTN1, thereby creating a positive feedback loop promoting HNSCC tumorigenesis and drug resistance.

Conclusions
These insights underscore the novel mechanisms that highlight ACTN1's pivotal role in driving HNSCC progression and resistance to chemotherapy, suggesting ACTN1 as a promising therapeutic target in HNSCC management.
“Calling for help: I need you to listen” - A qualitative study of callers’ experience of calls to the emergency medical communication centre
Authors: Spjeldnæs Trine Berglie , Nilsen Kristine A. Vik , Myrmel Lars , Sørnes Jan-Oddvar , Brattebø Guttorm 
Published: December 2023

Abstract
Background
The Emergency Medical Communications Center (EMCC) is essential in emergencies and often represents the public’s first encounter with the healthcare system. Previous research has mainly focused on the dispatcher’s perspective. Therefore, there is a lack of insight into the callers’ perspectives, the attainment of which may contribute significantly to improving the quality of this vital public service. Most calls are now made from mobile phones, opening up novel approaches for obtaining caller feedback using tools such as short-message services (SMS). Thus, this study aims to obtain a better understanding of callers’ actual experiences and how they perceived their interaction with the EMCC.

Methods
A combination of quantitative and qualitative study methods was used. An SMS survey was sent to the mobile phone numbers of everyone who had contacted 113 during the last months. This was followed by 31 semi-structured interviews with people either satisfied or dissatisfied. Thematic analysis was used to investigate the interviews.

Results
We received 1680 (35%) responses to the SMS survey, sent to 4807 unique numbers. Most respondents (88%) were satisfied, evaluating their experience as 5 or 6 on a six-point scale, whereas 5% answered with 1 or 2. The interviews revealed that callers were in distress before calling 113. By actively listening and taking the caller seriously, and affirming that it was the right choice to call the emergency number, the EMCC make callers experience a feeling of help and satisfaction, regardless of whether an ambulance was dispatched to their location.
If callers did not feel taken seriously or listened to, they were less satisfied. A negative experience may lead to a higher distress threshold and an adjusted strategy before the caller makes contact 113 next time. Callers with positive experiences expressed more trust in the healthcare systems.

Conclusions
For the callers, the most important was being taken seriously and listened to. Additionally, they welcomed that dispatchers express empathy and affirm that callers made the right choice to call EMCC, as this positively affects communication with callers. The 113 calls aimed to cooperate in finding a solution to the caller’s problem.
The factor structure of the Motivated Strategies for Learning Questionnaire (MSLQ): new methodological approaches and evidence
Authors: de Araujo Jhonys , Gomes Cristiano Mauro Assis , Jelihovschi Enio Galinkin 
Published: December 2023

Abstract
Background
The area of self-regulated learning integrates the fields of metacognition and self-regulation and assumes that the student is an active processor of information capable of self-regulating his learning by putting together the cognitive, metacognitive, and motivational components. The Motivated Strategies for Learning Questionnaire (MSLQ) is a benchmark for the measurement of self-regulated learning. However, the field of study does not show adequate evidence of its structural validity. The vast majority of studies involving this question present serious methodological mistakes, compromising the evidence of validity.

Objective
Our study investigates the structural validity of MSLQ including all 15 scales and corrects relevant mistakes in the previous studies.

Method
We tested different models through item confirmatory factor analysis in a convenience sample of 670 college students (M = 22.8 years, SD = 5.2) from a public Brazilian university in the technological area. The models with the ML, MLR, MLM and WLMSV estimators.

Results
Only WLSMV produced models with acceptable fit. The final model has a bi-factor structure with a general factor (self-regulated learning), 15 components as first-order factors, and four broad components as second-order factors. Twelve first-order components, all second-order components and the general factor had acceptable reliability. The components’ elaboration, intrinsic goal orientation and metacognitive self-regulation, did not show acceptable reliability, in terms of McDonald’s omega.

Conclusion
Considering the worldwide importance of the MSLQ, we do not recommend the use of the measurement of these components for clinical practice and psychoeducational diagnosis until new studies show that this low reliability only occurs in our sample. Our study shows new evidence, correcting many previous methodological mistakes and producing initial evidence favorable to the factor structure of the MSLQ.
Mental health effects of the COVID-19 pandemic on children and young adults: empirical analysis of the past, present and the way forward
Authors: Gupta Mayank 
Published: December 2023

Summary
The SARS-CoV-2 virus and its variants have had and are having serious implications for the mental health of the public. The critical limitations in the published literature for children, adolescents and young adults raise doubts about their clinical utility and overall generalisability. Amidst these gaps in knowledge, a twin study (Rimfeld et al) addresses several of these issues in relation to heritable individual differences and responses to environmental stressors. Besides calculating genetic correlation, the longitudinal study also compares symptoms at four different time points during the pandemic. These findings reflect a counterintuitive understanding of the role of resilience in the mental health of young adults in the UK. Unlike prior studies, this study focuses on methodological designs and underscores the applications of accurate statistical measures in observing these complex phenomena.
