Published: January 2024

Abstract
Background
Mechanical power (MP) is the total energy released into the entire respiratory system per minute which mainly comprises three components: elastic static power, Elastic dynamic power and resistive power. However, the energy to overcome resistance to the gas flow is not the key factor in causing lung injury, but the elastic power (EP) which generates the baseline stretch of the lung fibers and overcomes respiratory system elastance may be closely related to the ARDS severity. Thus, this study aimed to investigate whether EP is superior to other ventilator variables for predicting the severity of lung injury in ARDS patients.

Methods
We retrieved patient data from the Medical Information Mart for Intensive Care III (MIMIC-III) database. The retrieved data involved adults (≥ 18 years) diagnosed with ARDS and subjected to invasive mechanical ventilation for ≥ 48 h. We employed univariate and multivariate logistic regression analyses to investigate the correlation between EP and development of moderate-severe ARDS. Furthermore, we utilized restricted cubic spline models to assess whether there is a linear association between EP and incidence of moderate-severe ARDS. In addition, we employed a stratified linear regression model and likelihood ratio test in subgroups to identify potential modifications and interactions.

Results
Moderate-severe ARDS occurred in 73.4% (296/403) of the patients analyzed. EP and MP were significantly associated with moderate-severe ARDS (odds ratio [OR] 1.21, 95% confidence interval [CI] 1.15–1.28, p < 0.001; and OR 1.15, 95%CI 1.11–1.20, p < 0.001; respectively), but EP showed a higher area-under-curve (95%CI 0.72–0.82, p < 0.001) than plateau pressure, driving pressure, and static lung compliance in predicting ARDS severity. The optimal cutoff value for EP was 14.6 J/min with a sensitivity of 75% and specificity of 66%. Quartile analysis revealed that the relationship between EP and ARDS severity remained robust and reliable in subgroup analysis.

Conclusion
EP is a good ventilator variable associated with ARDS severity and can be used for grading ARDS severity. Close monitoring of EP is advised in patients undergoing mechanical ventilation. Additional experimental trials are needed to investigate whether adjusting ventilator variables according to EP can yield significant improvements in clinical outcomes.

Authors: Gu Yanqiong , Zhang Xunyi , Wang Ruixue , Wei Yingying , Peng Hao , Wang Kai , Li Han , Ji Yazhong 
Published: January 2024

Abstract
Background
Female fertility declines with increased maternal age, and this decline is even more rapid after the age of 35 years. Follicular fluid (FF) is a crucial microenvironment that plays a significant role in the development of oocytes, permits intercellular communication, and provides the oocytes with nutrition. Exosomes have emerged as being important cell communication mediators that are linked to age-related physiological and pathological conditions. However, the metabolomic profiling of FF derived exosomes from advanced age females are still lacking.

Methods
The individuals who were involved in this study were separated into two different groups: young age with a normal ovarian reserve and advanced age. The samples were analysed by using gas chromatography–time of flight mass spectrometry (GC–TOFMS) analysis. The altered metabolites were analysed by using Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis to identify the functions and pathways that were involved.

Results
Our data showed that metabolites in exosomes from FF were different between women of young age and women of advanced age. The set of 17 FF exosomal metabolites (P ≤ 0.05) may be biomarkers to differentiate between the two groups. Most of these differentially expressed metabolites in FF were closely involved in the regulation of oocyte number and hormone levels.

Conclusions
In this study, we identified differences in the metabolites of exosomes from FF between women of young age and women of advanced age. These different metabolites were tightly related to oocyte count and hormone levels. Importantly, these findings elucidate the metabolites of the FF exosomes and provide a better understanding of the nutritional profiles of the follicles with age.

Authors: Wang Yali , Li Shuchun , Jin Min , Xue Yunxing , Wang Dongjin , Zhou Qing 
Published: January 2024

Abstract
Background
Right-side aortic arch concomitant with Kommerell’s diverticulum (KD) is a rare and complex ailment, and there is no consensus on the optimal strategy to deal with this congenital anomaly. We retrospectively analyzed and summary of the cases treated in our center with individual treatment methods for different situations.

Methods
Between September 2018 and December 2021, 10 patients experienced surgical therapy at our institution who presented with a Kommerell’s diverticulum arising from an aberrant subclavian artery from the right-side aortic arch. Four main surgical techniques were applied to those patients: 1. total arch replacement with frozen elephant trunk implantation (n = 2); 2. hybrid procedure combining open arch repair and endovascular intervention (n = 1); 3. total endovascular repair using thoracic endovascular aortic repair (TEVAR) with or without left subclavian artery (LSCA) revascularization (n = 6); 4. direct repair underwent endoaneurysmorrhaphy. Clinical characteristics and outcomes were collected.

Results
The mean age of these 10 patients was 56.5 years (range 29–79 years) and only 1 woman. The pathology includes aortic dissection (n = 6) and aneurysm (n = 4). The mean diverticulum size was 41.4 [24.2–56.8] mm. There were no in-hospital deaths, and the median hospital stay was 22 [15–43] days. During the follow-up period (21.4 months, 1–44 months), one died of an unknown cause and one died of esophageal fistula. Two patients underwent second-stage endovascular intervention for distal lesion. And none of the patients had endoleak during the follow-up period.

Conclusions
Each of the procedures we have mentioned here has its advantages and disadvantages; individualized treatment should meet the appropriate indications. A single-branched stent graft is feasible and effective in the treatment of aortic disease combined with Kommerell’s diverticulum.

Published: January 2024

Abstract
Background
Clopidogrel is a widely prescribed prodrug that requires activation via specific pharmacogenes to exert its anti-platelet function. Genetic variations in the genes encoding its transporter, metabolizing enzymes, and target receptor lead to variability in its activation and platelet inhibition and, consequently, its efficacy. This variability increases the risk of secondary cardiovascular events, and therefore, some variations have been utilized as genetic biomarkers when prescribing clopidogrel.

Methods
Our study examined clopidogrel-related genes (CYP2C19, ABCB1, PON1, and P2Y12R) in a cohort of 298 healthy Emiratis individuals. The study used whole exome sequencing (WES) data to comprehensively analyze pertinent variations of these genes, including their minor allele frequencies, haplotype distribution, and their resulting phenotypes.

Results
Our data shows that approximately 37% (n = 119) of the cohort are likely to benefit from the use of alternative anti-platelet drugs due to their classification as intermediate or poor CYP2C19 metabolizers. Additionally, more than 50% of the studied cohort exhibited variants in ABCB1, PON1, and P2YR12 genes, potentially influencing clopidogrel’s transport, enzymatic clearance, and receptor performance.

Conclusions
Recognizing these alleles and genotype frequencies may explain the clinical differences in medication response across different ethnicities and predict adverse events. Our findings underscore the need to consider genetic variations in prescribing clopidogrel, with potential implications for implementing personalized anti-platelet therapy among Emiratis based on their genetic profiles.
Fenofibrate alleviates NAFLD by enhancing the PPARα/PGC-1α signaling pathway coupling mitochondrial function
Authors: Wang Xuemei , Wang Jieying , Ying Cao , Xing Yuan , Su Xuan , Men Ke 
Published: January 2024

Abstract
Background
To comprehend the influences of fenofibrate on hepatic lipid accumulation and mitochondrial function-related signaling pathways in mice with non-alcoholic fatty liver disease (NAFLD) secondary to high-fat diets together with free fatty acids-influenced HepG2 cells model.

Materials and methods
A random allocation of male 6-week C57BL/6J mice into three groups was done, including controls, model (14 weeks of a high-fat diet), and fenofibrate [similar to the model one with administered 0.04 g/(kg.d) fenofibrate by gavage at 11 weeks for 4 weeks] groups, which contained 10 mice each. This study verified NAFLD pathogenesis via mitochondrial functions in hepatic pathological abnormalities, liver index and weight, body weight, serum biochemical indexes, oxidative stress indicators, mitochondrial function indexes, and related signaling pathways. The effect of fenofibrate intervention was investigated in NAFLD model mice. In vitro, four groups based on HepG2 cells were generated, including controls, the FFA model (1.5 mmol/L FFA incubation for 24 h), LV-PGC-1α intervention (similar to the FFA model one after PPARGC1A lentivirus transfection), and LV control intervention (similar to the FFA model one after negative control lentivirus transfection) groups. The study investigated the mechanism of PGC-1α related to lipid decomposition and mitochondrial biosynthesis by Oil red O staining, colorimetry and western blot.

Results
In vivo experiments, a high-fat diet achieved remarkable changes regarding liver weight, liver index, serum biochemical indicators, oxidative stress indicators, liver pathological changes, mitochondrial function indicators, and body weight of the NAFLD model mice while fenofibrate improved the objective indicators. In the HepG2 cells model, the lipid accumulation increased significantly within the FFA model group, together with aggravated hepatocytic damage and boosted oxidative stress levels. Moreover, FFA induced excessive mitosis into fragmented in mitochondrial morphology, ATP content in cells decreased, mtDNA replication fold decreased, the expression of lipid decomposition protein PPARα reduced, mitochondrial biosynthesis related protein PGC-1α, NRF-1 and TFAM decreased. PGC-1α overexpression inhibited lipid deposition by improving mitochondrial biosynthesis and lipid decomposition.

Conclusion
Fenofibrate up-regulated PPARα/PGC-1α signaling pathway, promoted mitochondrial β-oxidation, reduced oxidative stress damage and lipid accumulation of liver. PGC-1α overexpression enhanced mitochondrial biosynthesis and ATP production, and reduced HepG2 intracellular accumulation of lipids and oxidative stress.
Lactadherin immunoblockade in small extracellular vesicles inhibits sEV-mediated increase of pro-metastatic capacities
Authors: Durán-Jara Eduardo , del Campo Matías , Gutiérrez Valentina , Wichmann Ignacio , Trigo César , Ezquer Marcelo , Lobos-González Lorena 
Published: January 2024

Abstract
Background
Tumor-derived small extracellular vesicles (sEVs) can promote tumorigenic and metastatic capacities in less aggressive recipient cells mainly through the biomolecules in their cargo. However, despite recent advances, the specific molecules orchestrating these changes are not completely defined. Lactadherin is a secreted glycoprotein typically found in the milk fat globule membrane. Its overexpression has been associated with increased tumorigenesis and metastasis in breast cancer (BC) and other tumors. However, neither its presence in sEVs secreted by BC cells, nor its role in sEV-mediated intercellular communication have been described. The present study focused on the role of lactadherin-containing sEVs from metastatic MDA-MB-231 triple-negative BC (TNBC) cells (sEV-MDA231) in the promotion of pro-metastatic capacities in non-tumorigenic and non-metastatic recipient cells in vitro, as well as their pro-metastatic role in a murine model of peritoneal carcinomatosis.

Results
We show that lactadherin is present in sEVs secreted by BC cells and it is higher in sEV-MDA231 compared with the other BC cell-secreted sEVs measured through ELISA. Incubation of non-metastatic recipient cells with sEV-MDA231 increases their migration and, to some extent, their tumoroid formation capacity but not their anchorage-independent growth. Remarkably, lactadherin blockade in sEV-MDA231 results in a significant decrease of those sEV-mediated changes in vitro. Similarly, intraperitoneally treatment of mice with MDA-MB-231 BC cells and sEV-MDA231 greatly increase the formation of malignant ascites and tumor micronodules, effects that were significantly inhibited when lactadherin was previously blocked in those sEV-MDA231.

Conclusions
As to our knowledge, our study provides the first evidence on the role of lactadherin in metastatic BC cell-secreted sEVs as promoter of: (i) metastatic capacities in less aggressive recipient cells, and ii) the formation of malignant ascites and metastatic tumor nodules. These results increase our understanding on the role of lactadherin in sEVs as promoter of metastatic capacities which can be used as a therapeutic option for BC and other malignancies.
Motives for Caffeine Consumption Questionnaire (MCCQ): validity and reliability of Turkish version
Authors: Küçükkasap Tuğba , Uslu Burcu 
Published: January 2024

Abstract
Objectives
The aims of this study are to make the Turkish validity and reliability of the scale that explain why caffeine intake. Additionally, it is crucial to highlight that the adaptation of the scale involved a confirmatory factor analysis (CFA) to validate its structure and the need for this adaptation in the Turkish context.

Materials and methods
The study was carried out with a total of 200 university students, comprised of 93.5% female and 6.5% male participants, with a mean age of 21.74 ± 6.15 years who were actively studying in the faculties of the universities who accepted to participate voluntarily in the study were included. The Turkish version of the Motives for Caffeine Consumption Questionnaire (MCCQ) scale and the MCCQ was used as the data collection tools. To evaluate the statistical analysis findings, the margin of error was taken as 5%. The entire application was carried out with the R-project software. CFA was used to test the adaptation of the MCCQ scale from English to Turkish.

Results
The alpha internal consistency coefficient for the whole scale was calculated as 0.959. Just like the original scale, the Turkish version shows a six-factor structure: habit, alertness, mood, social, taste, and symptom management. In MCCQ-TR, it showed a low level of positive correlation with Yale Food Addiction Scale (YFAS). For the final scale with 23 items and 6 sub-dimensions, it was determined that the fit indices were at an acceptable level, and the internal consistency was highly reliable for all sub-dimensions and the total scale.

Conclusions
It has been determined that the Turkish version of the MCCQ is a valid and reliable measurement tool to operationalize the motives of caffeine consumption and to reveal possible differences in the motives regarding gender, age, and the type of caffeinated products consumed. The use of CFA in adapting the scale ensures the robustness of the structural validity in the Turkish context, making this adaptation a valuable contribution to the field.
Avoiding adverse events in interventional radiology – a systematic review on the instruments
Authors: Blum Sophia Freya Ulrike , Hoffmann Ralf-Thorsten 
Published: January 2024

Abstract
Background
Avoiding AEs is a pivotal fundament for high patient safety in an efficient interventional radiology (IR) department. Although IR procedures are considered to have a lower risk than their surgical alternatives, they account for one third of all radiological adverse events (AEs) and in general, the number of AEs is increasing. Thus, measures to prevent AEs in IR are of interest.

Methods
A systematic literature search was conducted via handsearch and Ovid. A structured data extraction was performed with all included studies and their quality of evidence was evaluated. Finally, data were aggregated for further statistical analysis.

Results
After screening 1,899 records, 25 full-text publications were screened for eligibility. Nine studies were included in the review. Of those, four studies investigated in simulator training, one in team training, three in checklists, and one in team time-out. Eight were monocenter studies, and five were conducted in a non-clinical context. Study quality was low. Aggregation and analysis of data was only possible for the studies about checklists with an overall reduction of the median error per procedure from 0.35 to 0.06, observed in a total of 20,399 and 58,963 procedures, respectively.

Conclusion
The evidence on the instruments to avoid AEs in IR is low. Further research should be conducted to elaborate the most powerful safety tools to improve patient outcomes in IR by avoiding AEs.
Beyond pediatrics: noninvasive spinal neuromodulation improves motor function in an adult with cerebral palsy
Authors: Sachdeva Rahul , Girshin Kristin , Shirkhani Yousef , Gad Parag 
Published: January 2024

AbstractRegaining motor function in individuals with cerebral palsy (CP) has been predominantly studied in children, resulting in an underrepresentation of adults in research efforts. We tested the efficacy of noninvasive spinal neuromodulation with neurorehabilitation (Spinal Cord Innovation in Pediatrics; SCiP™ therapy). A 60-year-old CP participant underwent 8 weeks of SCiP™ therapy, resulting in significant motor recovery measured by 14.2-points increase in gross motor function measure (GMFM-88) score, ~ three times the Minimal Clinically Important Difference (MCID) of 5-points. This represented gains in kneeling, sitting, and walking functions. The improvement in GMFM-88 score was maintained above the MCID at the follow up visit (10.3 points above the baseline), twenty weeks following the last therapy session, indicating a persistent effect of the therapy. Our preliminary findings support the therapeutic promise of SCiP™ therapy for enhancing motor function in CP adults. Broader investigations are needed to establish its wider applicability.
Analysis of social media compliance with cannabis advertising regulations: evidence from recreational dispensaries in Illinois 1-year post-legalization
Authors: Marinello Samantha , Valek Rebecca , Powell Lisa M. 
Published: January 2024

Abstract
Background
In the USA, an increasing number of states have legalized commercial recreational cannabis markets, allowing a private industry to sell cannabis to those 21 and older at retail locations known as dispensaries. Research on tobacco and alcohol suggests this new industry will use aggressive marketing tactics to attract new users and promote greater intensity of use. Of concern is that cannabis company advertising campaigns may be appealing to youth, promote false or misleading health claims, and disproportionately target low-income and minority communities. In this study, we evaluated recreational cannabis dispensary compliance with advertising regulations on social media in the state of Illinois.

Methods
Primary data were collected from a census of recreational dispensary Facebook and Twitter business pages during the first year of recreational sales in 2020. A quantitative content analysis was conducted to systematically analyze the data; a codebook that detailed a protocol for classifying posts was developed prior to the analysis using advertising regulations outlined in the Illinois Cannabis Regulation and Tax Act. Violations of advertising regulations were organized into three categories: advertisements that may be appealing to youth (< 21 years old), advertisements that make health claims, and other advertising violations. The data were analyzed cross-sectionally and longitudinally. Additionally, differences in compliance were assessed by dispensary and neighborhood characteristics.

Results
The results of the analysis revealed substantial and persistent non-compliance throughout the entire study period. Overall, nearly one third of posts had at least one violation and approximately one in ten posts met the criteria for appealing to youth or contained health claims. The majority of posts with health claims included health claims that were not qualifying conditions for medical cannabis access in the state of Illinois. No differences in compliance by neighborhood and dispensary characteristics were found.

Conclusions
The findings from this study suggest that systematic monitoring and enforcement is needed to ensure compliance with advertising regulations.
Comparison of perceptions in Canada and USA regarding cannabis and edibles
Authors: Music Janet , Sterling Brian , Charlebois Sylvain , Goedhart Christine 
Published: January 2024

Abstract
Background
Canada took a national approach to recreational cannabis that resulted in official legalization on October 17, 2018. In the United States (US), the approach has been more piecemeal, with individual states passing their own laws regulating adult use. The objective of this study was to compare the two jurisdictions.

Methods
Two exploratory, quantitative surveys were administered in May of 2021 in both Canada and the US. One thousand forty-seven Canadian and 1037 US residents (age 19 and older) were surveyed on approaches to and attendant regulations of consumer cannabis. Tests of significance were performed to analyze differences between two groups.

Results
No statistically significant differences exist between the two countries in terms of cannabis legalization acceptance. Usage rates among adults was similar with 45% of Canadians and 42% of Americans confirming they consume cannabis. Respondents maintain that they intend to increase their usage, with edibles attracting a rising level of interest from consumers.

Conclusions
Results suggest that public policy in both Canada and the USA needs to change to reflect rapidly evolving acceptance of cannabis products in North America to realize potential economic returns.
