Published: December 2023

Abstract
Background
CD147, a transmembrane glycoprotein, has been implicated in various cancer-related processes but its role in breast cancer remains poorly understood. Herein, we investigated the expression of CD147 in different breast cancer cell lines and explored its functional roles, including migration, invasion, drug resistance and modulation of key proteins associated with cancer progression.

Methods
The expression of CD147 was assessed in MCF-10 A, BT549, MDA-MB-231 and MCF-7 breast cancer cell lines using qRT-PCR and Western blotting, following which lyposome transfections were performed, leading overexpression of CD147 in BT549 cells and knockdown of CD147 in MCF-7 cells. Scratch assays and Transwell invasion and were performed to evaluate the cells’ migration and invasion abilities. Sensitivity to 5-FU was determined via CCK-8 assays, and the expression of Snail1, E-cadherin, Vimentin, MMP-9 and the MAPK/ERK pathway were analyzed by qRT-PCR and Western blotting.

Results
Compared with normal beast epithelial cells, CD147 was highly expressed in all breast cancer cell lines, with the highest overexpression observed in MCF-7 cells and the lowest overexpression observed in BT549 cells. Overexpression of CD147 in BT549 cells increased, migration, invasion, viability and resistance to 5-FU of BT549 cells, while CD147 knockdown in MCF-7 cells reduced these properties of MCF-7 cells. Furthermore, CD147 influenced the expression of Snail1, Vimentin, E-cadherin, and MMP-9, suggesting its involvement in epithelial-mesenchymal transition (EMT) regulation. The MAPK/ERK pathway was activated by CD147 in BT549 cells, as indicated by increased p-MEK/MEK ratio and p-ERK/ERK ratio. In contrast, CD147 silencing in MCF-7 cells resulted in reduced p-MEK/MEK ratio and p-ERK/ERK ratio.

Conclusion
In summary, our findings suggest CD147 as a potential therapeutic target in breast cancer treatment, particularly in cases where drug resistance and metastasis are concerns, worthy of further explorations.

Abstract
Background
The transition to motherhood is characterized by physical, psychological, social, and relational changes. Quality of life (QoL) changes substantially during this transition. Higher QoL is associated with social support, essential for coping with the challenges and changes of becoming a mother. An early universal home visiting program (New Families) is developed to strengthen and support families. The study aims to evaluate the impact of New Families on first-time mothers’ QoL and to investigate the association between their QoL, social support, and selected possible predictive factors.

Methods
A prospective non-randomized controlled study with parallel group design. Child Health Services in five city districts of Oslo were matched in intervention and control groups. First-time mothers were allocated based on the residential area and assessed at pregnancy week 28 (N = 228), six weeks postpartum (N = 184), and three months postpartum (N = 167). Measures of the World Health Organization Quality of Life brief, Perinatal Infant Care Social Support Scale, and background variables were collected from October 2018 to June 2020. Multivariate linear regression models were applied to examine intervention impact and assess associations.

Results
Our data did not reveal a significant association between New Families intervention and the QoL levels of first-time mothers at three months postpartum. Thus, we analyzed the whole sample together. Emotional support was significantly associated with higher QoL levels in the physical health (B = 0.19, 95%CI [0.04 to 0.34]) and social relationships (B = 0.40, 95%CI [0.20 to 0.60]) domains. Appraisal support was significantly associated with higher QoL levels in the psychological (B = 0.34, 95%CI [0.18 to 0.50]) and environment (B = 0.33, 95%CI [0.19 to 0.48]) domains. QoL levels in pregnancy were significantly associated with QoL levels postpartum, showing small to medium effect size (ES = 0.30 to 0.55), depending on the domain.

Conclusions
Further research, including qualitative interviews, could provide more insights into the impact of New Families on QoL. A positive association between QoL levels in pregnancy and postpartum suggests that postnatal interventions targeting improved QoL could potentially improve postpartum QoL. Emotional and appraisal support seems beneficial for first-time mothers’ QoL and could be provided and facilitated by public health nurses.

The association between mechanical temporal summation, state anxiety at baseline, and persistent low back pain: a 12-month prospective cohort study
Authors: Dietrich Nicole , Luomajoki Hannu , Hotz-Boendermaker Sabina 
Published: December 2023

Abstract
Background
Persons with acute low back pain (LBP) have a good prognosis for regaining function, while pain often persists. Neurobiological and psychosocial factors are recognized to amplify pain responses, as reported for central sensitization. This study investigated the combination of mechanical temporal summation (TS) chosen to characterize central sensitization and state anxiety representing a psychological factor and their association with persistent pain.

Methods
A longitudinal prospective cohort study including 176 participants aged between 18 and 65 with acute LBP was performed. The following independent variables were analyzed at baseline: The mechanical TS at the lower back, of whom the Wind-up ratio (WUR) was calculated, and the state anxiety level measured with the State and Trait Anxiety Inventory (STAI-S). The outcome pain intensity was assessed at baseline and 2,3,6 and 12 months after the onset of acute LBP with the Numeric Rating Scale 0–10 (NRS). Linear mixed models (LMM) were used to analyze the association of the independent variables with pain intensity over time.

Results
The mean baseline WUR was 1.3 (SD 0.6) for the right and 1.5 (SD 1.0) for the left side. STAI-S revealed a mean score of 43.1 (SD 5.2). Pain intensity was, on average, 5.4 points (SD 1.6) on the NRS and decreased over one year to a mean of 2.2 (SD 2.4). After one year, 56% of the participants still experienced pain. The LMM revealed a considerable variation, as seen in large confidence intervals. Therefore, associations of the independent variables (WUR and STAI-S) with the course of the outcome pain intensity over one year were not established.

Conclusion
This investigation did not reveal an association of mechanical TS and state anxiety at baseline with pain intensity during the one-year measurement period. Pain persistence, mediated by central sensitization, is a complex mechanism that single mechanical TS and state anxiety cannot capture.
Both gastrocnemius aponeurosis flaps and semitendinosus tendon grafts are effective in the treatment of chronic Achilles tendon ruptures – a systematic review

Published: December 2023

Abstract
Introduction
A chronic Achilles tendon rupture (ATR) is defined as an ATR that has been left untreated for more than four weeks following rupture. This systematic review aims to summarize the outcomes of chronic ATR treated using either a gastrocnemius aponeurosis flap or semitendinosus tendon graft.

Methods
A systematic search was conducted in three databases (PubMed, Scopus and Cochrane), for studies describing outcomes after surgical treatment of chronic ATR using gastrocnemius aponeurosis flaps or semitendinosus tendon grafts with more than 10 patients included. The studies were assessed for quality and risk of bias using the Methodological Items used to assess risk of bias in Non-Randomized Studies (MINORS).

Results
Out of the 818 studies identified with the initial search, a total of 36 studies with 763 individual patients were included in this systematic review. Gastrocnemius aponeurosis flap was used in 21 and semitendinosus tendon graft was used in 13 of the studies. The mean (SD) postoperative Achilles tendon Total Rupture Score (ATRS) for patients treated with a gastrocnemius aponeurosis flap was 83 (14) points and the mean (SD) American Orthopaedic Foot and Ankle Score (AOFAS) was 96 (1.7) points compared with ATRS 88 (6.9) points and AOFAS 92 (5.6) points for patients treated with a semitendinosus tendon graft. The included studies generally had low-quality according to MINORS, with a median of 8 (range 2–13) for all studies.

Conclusion
Both gastrocnemius aponeurosis flaps and semitendinosus tendon grafts give acceptable results with minimal complications and are valid methods for treating chronic ATR. The main difference is more wound healing complications in patients treated with a gastrocnemius aponeurosis flap and more sural nerve injuries in patients treated with a semitendinosus grafts. The current literature on the subject is of mainly low quality and the absence of a patient-related outcome measure validated for chronic ATR makes comparisons between studies difficult.

Minimal pre-operative leg length discrepancy as a risk factor of post-operative leg length discrepancy after total hip arthroplasty: a retrospective study of patients with non-traumatic osteonecrosis of the femoral head
Authors: Kim Hong Seok , Lee Han Jin , Yoo Jeong Joon 
Published: December 2023

Abstract
Background
Leg length discrepancy (LLD) is one of the troublesome complications of total hip arthroplasty (THA). Previously, several risk factors have been suggested, but they were subjected to their inherent limitations. By controlling confounding variables, we hypothesized that known risk factors be re-evaluated and novel ones be discovered. This study aimed to analyze the independent risk factors for LLD after primary THA in patients with non-traumatic osteonecrosis of the femoral head (ONFH).

Methods
We retrospectively reviewed patients with non-traumatic ONFH who underwent unilateral THA between 2014 and 2021. All patients were operated by one senior surgeon using a single implant. Demographic data, surgical parameters, and radiological findings (pre-operative LLD, Dorr classification, and femoral neck resection) were analyzed to identify the risk factors of ≥ 5 mm post-operative LLD based on radiological measurement and to calculate odds ratios by logistic regression analysis. Post hoc power analysis demonstrated that the number of analyzed patients was sufficient with 80% power.

Results
One hundred and eighty-six patients were analyzed, including 96 females, with a mean age of 58.8 years at the time of initial THA. The average post-operative LLD was 1.2 ± 2.9 mm in the control group and 9.7 ± 3.2 mm in the LLD group, respectively. The LLD group tended to have minimal pre-operative LLD than the control group (-3.2 ± 5.1 mm vs. -7.9 ± 5.8 mm p = 2.38 × 10− 8). No significant difference was found between the groups in age, gender, body mass index, femoral cortical index, and implant size.

Conclusion
Mild pre-operative LLD is associated with an increased risk of post-operative LLD after primary THA in patients with ONFH. Thus, surgeons should recognize pre-operative LLD to achieve an optimal outcome and must inform patients about the risk of developing LLD.

Published: December 2023

Abstract
Introduction
Pelvic Organ Prolapse is the descent of one or more of the anterior vaginal wall, posterior vaginal wall, the uterus, or the apex of the vagina. Surgical intervention addresses both anatomical defect and associated symptoms. The landscape of prolapse surgery has been evolving constantly over years. Emerging evidences either support or challenge existing surgical treatment options, making urogynecology a dynamic field. In Ethiopia, the surgical management of pelvic organ prolapse has transitioned from abdominal to vaginal hysterectomy, supplemented later by McCall’s culdoplasty. Disparities exist in the national uniformity of surgical approaches, linked to the establishment of Urogynecology centers in certain institutions.

Objectives
This study was done to assess the surgical management practice of Ethiopian gynecologists on pelvic organ prolapse.

Methods
A cross-sectional study encompassing all Gynecologists in Ethiopia took place between January to June 2021. Information was gathered through online Google forms crafted in English. Subsequently, the collected data underwent verification, coding, and entry into Epi info 7 before being exported to SPSS version 22 software for descriptive statistical analysis.

Results
We reached 280 gynecologists out of the 450 practicing in the Ethiopia making 62% response rate. Anterior colporrhaphy (98.6%), vaginal hysterectomy with McCall’s cul-do-plasty (51.8%), and Posterior colporrhaphy (97.5%) were the most commonly performed surgical procedures for anterior vaginal wall prolapse, apical prolapse (uterine/cervical), and posterior vaginal wall prolapse respectively. Only 3.2% and 0.7% of the gynecologists conducted abdominal and vaginal paravaginal repair for anterior vaginal wall prolapse. Sacrospinous ligament fixation and sacrocolpopexy for apical prolapse were carried out by 32.9% and 9.3% of the gynecologists respectively. Site-specific posterior repair for posterior vaginal wall prolapse was performed only by 23.9% of the gynecologists. The main reasons mentioned not to perform paravaginal repair, sacrocolpopexy, sacrospinous ligament fixation, and site-specific posterior repair were lack of skill and lack of appropriate materials.

Conclusion and recommendation
Most gynecologists in Ethiopian continue to perform vaginal hysterectomy and colporrhaphy procedures for treatment of pelvic organ prolapse due primarily to lack of skill and appropriate materials to perform the alternative procedures. Implementing short term training on alternative surgical treatment options of pelvic organ prolapse with provision of suitable materials and increasing the number of urogynecologists in the country in the long run holds the potential to enhance the standard of care of women with the condition.

Published: December 2023

Abstract
Introduction
Liver X Receptor (LXR) agonists could attenuate the development of atherosclerosis but bring excess lipid accumulation in the liver. Danlou Recipe was believed to be a benefit for improving the lipid profile. Thus, it is unclear whether Danlou Recipe could attenuate hyperlipidemia without excess lipid accumulated in the liver of mice. This study aimed to clarify if Danlou Recipe could alleviate the progression of hyperlipidemia in mice without extra lipids accumulated in the liver.

Methods
Male murine macrophage RAW264.7 cells and murine peritoneal macrophages were used for the in vitro experiments. Cellular cholesterol efflux was determined using the fluorescent cholesterol labeling method. Those genes involved in lipid metabolism were evaluated by qRT‐PCR and western blotting respectively. In vivo, a mouse model of hyperlipidemia induced by P407 was used to figure out the effect of Danlou Recipe on reverse cholesterol transport (RCT) and hyperlipidemia. Ethanol extract of Danlou tablet (EEDL) was prepared by extracting the whole powder of Danlou Prescription from ethanol, and the chemical composition was analyzed by ultra-performance liquid chromatography (UPLC).

Results
EEDL inhibits the formation of RAW264.7 macrophage-derived foam cells, and promotes ABCA1/apoA1 conducted cholesterol efflux in RAW264.7 macrophages and mouse peritoneal macrophages. In the P407-induced hyperlipidemia mouse model, oral administration of EEDL can promote RCT in vivo and improve fatty liver induced by a high-fat diet. Consistent with the findings in vitro, EEDL promotes RCT by upregulating the LXR activities.

Conclusion
Our results demonstrate that EEDL has the potential for targeting RCT/LXR in the treatment of lipid metabolism disorders to be developed as a safe and effective therapy.
Knowledge and perceived competence with sexual and gender minority healthcare topics among medical students and medical school faculty
Authors: Rhodes Allison , Barbati Zachary , Tybor David , Louis Joshua St. 
Published: December 2023

Abstract
Background
Despite changes in social attitudes in the United States over the last decade, sexual and gender minority (SGM) individuals continue to face significant health disparities, driven partly by disproportionately higher rates of self-reported discrimination and harassment when seeking healthcare. Historically, physicians have received little to no required training on how to provide sensitive, competent care to SGM patients, and continue to demonstrate poor competency with SGM topics despite calls for increased education and published guidelines to promote competency. The present study aimed to investigate competency with SGM topics among both faculty and medical students at one institution.

Methods
The authors distributed an anonymous online survey (2020–2021) to medical students and student-facing faculty at one allopathic medical school in the United States. The objective of the study was to evaluate knowledge, clinical skills, and self-reported competence with SGM topics.

Results
Of survey respondents, 223 medical students and 111 faculty were included in final analysis. On average, medical students were significantly more likely to answer General Knowledge questions correctly (97.2%) compared to faculty (89.9%). There were no significant differences in responses to Clinical Knowledge questions between medical students and faculty. however medical students were significantly more likely to report competence with eliciting a thorough sexual history, and faculty were significantly more likely to report receiving adequate clinical training and supervision to work with lesbian, gay, and bisexual patients.

Conclusions
Medical students demonstrated significantly higher general knowledge about SGM topics compared to faculty. Medical students and faculty demonstrated similarly low average clinical knowledge, with percent correct 65.6% for students and 62.7% for faculty. Despite significant differences in general knowledge and low clinical knowledge, medical students and faculty self-reported similar levels of competence with these topics. This indicates insufficient curricular preparation to achieve the AAMC competencies necessary to care for SGM patients.

Published: December 2023

Abstract
Background
The accuracy of electrocardiogram (ECG) interpretation by doctors are affected by the available clinical information. However, having a complete set of clinical details before making a diagnosis is very difficult in the clinical setting especially in the early stages of the admission process. Therefore, we developed an artificial intelligence-assisted ECG diagnostic system (AI-ECG) using natural language processing to provide screened key clinical information during ECG interpretation.

Methods
Doctors with varying levels of training were asked to make diagnoses from 50 ECGs using a common ECG diagnosis system that does not contain clinical information. After a two-week-blanking period, the same set of ECGs was reinterpreted by the same doctors with AI-ECG containing clinical information. Two cardiologists independently provided diagnostic criteria for 50 ECGs, and discrepancies were resolved by consensus or, if necessary, by a third cardiologist. The accuracy of ECG interpretation was assessed, with each response scored as correct/partially correct = 1 or incorrect = 0.

Results
The mean accuracy of ECG interpretation was 30.2% and 36.2% with the common ECG system and AI-ECG system, respectively. Compared to the unaided ECG system, the accuracy of interpretation was significantly improved with the AI-ECG system (P for paired t-test = 0.002). For senior doctors, no improvement was found in ECG interpretation accuracy, while an AI-ECG system was associated with 27% higher mean scores (24.3 ± 9.4% vs. 30.9 ± 10.6%, P = 0.005) for junior doctors.

Conclusion
Intelligently screened key clinical information could improve the accuracy of ECG interpretation by doctors, especially for junior doctors.
Spiritual care competency and its relationship with clinical self-efficacy in nursing students
Authors: Sahebi Zahra , Barkhordari-Sharifabad Maasoumeh 
Published: December 2023

Abstract
Background
Spiritual care occupies a special place in holistic care and improving the quality of services provided to patients. The component of clinical self-efficacy is recognized as a prerequisite for clinical capacity and competency. The current study determined the level of spiritual care competency and its relationship with clinical self-efficacy in nursing students.

Methods
This cross-sectional study was conducted on 194 nursing students studying in medical sciences universities in Yazd, Iran, who were selected by convenient sampling. Data collection tools were a spiritual care competency scale and nursing students’ clinical self-efficacy questionnaire. The gleaned data were analyzed by SPSS20 using descriptive and inferential statistics.

Results
The mean scores of spiritual care competency and clinical self-efficacy of students were 70.29 ± 9.58 and 102.40 ± 21.57, respectively. The results of Pearson’s correlation coefficient test showed that clinical self-efficacy had a positive significant correlation with spiritual care competency (p = 0.04, r = 0.14). The mean score of spiritual care competency was higher in female students (71.10 ± 9.81) than male students (67.50 ± 8.23) with a statistically significant difference (p < 0.05). The regression test results suggested that clinical self-efficacy can be considered as a predictor of spiritual care competency.

Conclusion
The results revealed that spiritual care competency in nursing students was at an average level, and the higher the level of clinical self-efficacy is, the more developed the spiritual care competency will be. Thus, nursing educators and health system managers should pay special attention to improving the clinical self-efficacy of nursing students to develop their spiritual care competency.
