Abstract Background The trauma mortality rate is higher in the elderly compared with younger patients. Ageing is associated with physiological changes in multiple systems and correlated with frailty. Frailty is a risk factor for mortality in elderly trauma patients. We aim to provide evidence-based guidelines for the management of geriatric trauma patients to improve it and reduce futile procedures. Methods Six working groups of expert acute care and trauma surgeons reviewed extensively the literature according to the topic and the PICO question assigned. Statements and recommendations were assessed according to the GRADE methodology and approved by a consensus of experts in the field at the 10th international congress of the WSES in 2023. Results The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage, including drug history, frailty assessment, nutritional status, and early activation of trauma protocol to improve outcomes. Acute trauma pain in the elderly has to be managed in a multimodal analgesic approach, to avoid side effects of opioid use. Antibiotic prophylaxis is recommended in penetrating (abdominal, thoracic) trauma, in severely burned and in open fractures elderly patients to decrease septic complications. Antibiotics are not recommended in blunt trauma in the absence of signs of sepsis and septic shock. Venous thromboembolism prophylaxis with LMWH or UFH should be administrated as soon as possible in high and moderate-risk elderly trauma patients according to the renal function, weight of the patient and bleeding risk. A palliative care team should be involved as soon as possible to discuss the end of life in a multidisciplinary approach considering the patient’s directives, family feelings and representatives' desires, and all decisions should be shared. Conclusions The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage based on assessing frailty and early activation of trauma protocol to improve outcomes. Geriatric Intensive Care Units are needed to care for elderly and frail trauma patients in a multidisciplinary approach to decrease mortality and improve outcomes. Graphical abstract

Abstract Scalar field theories with quartic interactions are of central interest in the study of second-order phase transitions. For three-dimensional theories, numerous studies make use of the fixed-dimensional perturbative computation of [B. Nickel, D. Meiron, and G. Baker Jr, Compilation of 2-pt and 4-pt graphs for continuous spin model, University of Guelph report (1977)], unfortunately left unpublished. We independently verify the results of Nickel et al., and we extend the computation to the eighth order in the coupling constant. The results of our calculations, together with the tools developed, are made available in Phi4tools, a user-friendly package that allows displaying the information about the individual Feynman diagrams, including the numerical values for the diagrams for zero, two, and four-point functions. We also provide the perturbative series up to order eight for the renormalization-group functions for the O(N) and cubic anisotropic models.

Abstract Background Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann’s procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P

Abstract Functional trade-offs can affect patterns of morphological and ecological evolution as well as the magnitude of morphological changes through evolutionary time. Using morpho-functional landscape modelling on the cranium of 132 carnivore species, we focused on the macroevolutionary effects of the trade-off between bite force and bite velocity. Here, we show that rates of evolution in form (morphology) are decoupled from rates of evolution in function. Further, we found theoretical morphologies optimising for velocity to be more diverse, while a much smaller phenotypic space was occupied by shapes optimising force. This pattern of differential representation of different functions in theoretical morphological space was highly correlated with patterns of actual morphological disparity. We hypothesise that many-to-one mapping of cranium shape on function may prevent the detection of direct relationships between form and function. As comparatively only few morphologies optimise bite force, species optimising this function may be less abundant because they are less likely to evolve. This, in turn, may explain why certain clades are less variable than others. Given the ubiquity of functional trade-offs in biological systems, these patterns may be general and may help to explain the unevenness of morphological and functional diversity across the tree of life.

Abstract Background The COVID-19 pandemic has increased the incidence of ventilator-associated pneumonia (VAP) among critically ill patients. However, a comparison of VAP incidence in COVID-19 and non-COVID-19 cohorts, particularly in a context with a high prevalence of multidrug-resistant (MDR) organisms, is lacking. Material and Methods We conducted a single-center, mixed prospective and retrospective cohort study comparing COVID-19 patients admitted to the intensive care unit (ICU) of the “Città della Salute e della Scienza” University Hospital in Turin, Italy, between March 2020 and December 2021 (COVID-19 group), with a historical cohort of ICU patients admitted between June 2016 and March 2018 (NON-COVID-19 group). The primary objective was to define the incidence of VAP in both cohorts. Secondary objectives were to evaluate the microbial cause, resistance patters, risk factors and impact on 28 days, ICU and in-hospital mortality, duration of ICU stay, and duration of hospitalization). Results We found a significantly higher incidence of VAP (51.9% - n = 125) among the 241 COVID-19 patients compared to that observed (31.2% - n = 78) among the 252 NON-COVID-19 patients. The median SOFA score was significantly lower in the COVID-19 group (9, Interquartile range, IQR: 7–11 vs. 10, IQR: 8–13, p

Abstract Background Lithium stands as the gold standard in treating bipolar disorders (BD). Despite numerous clinical factors being associated with a favorable response to lithium, comprehensive studies examining the collective influence of clinical variables alongside psychopathological dimensions are lacking. Our study aims to enhance comprehension of lithium response in individuals with BD by integrating clinical variables with psychopathological traits and early adverse events. Methods We assessed 201 patients with BD for clinical characteristics, childhood trauma, temperament traits, impulsivity, and aggression. Lithium response was evaluated using the gold standard Alda scale, and predictors of lithium response were estimated through a multivariate model. Results On the total sample, 61 (30.3%) patients were lithium responders according to the Alda scale. Comparatively, lithium responders, in contrast to non-responders, demonstrated a higher prevalence of the mania-depression-interval (MDI) cycle, a more frequent diagnosis of BD type I, and reported an earlier age of onset. They also exhibited less lifetime substance abuse, emotional, physical, and sexual abuse, while scoring higher on hyperthymic and irritable temperament scales. In multivariate analyses, only the MDI cycle (OR,3.47; 95%CI,1.61–7.50) hyperthymic (OR,1.20; 95%CI,1.02–1.41) and irritable temperament (OR,1.28; 95%CI,1.08–1.52) persisted as significant predictors of a positive response to lithium treatment, while emotional (OR,0.87; 95%CI,0.76–0.98) and physical abuse (OR,0.83; 95%CI,0.70–0.98) were predictors of non-response. Conclusions In evaluating lithium response in BD, our study highlights the importance of considering clinical variables alongside temperament and childhood adversities. The assessment of hyperthymic and irritable temperament, emotional and physical abuse together with the type of cycle is of particular importance. Furthermore, our findings underscore the significance of systematically assessing the type of cycle in patients with BD through the use of life charts.

Abstract The African buffalo, Syncerus caffer, is a key species in African ecosystems. Like other large herbivores, it plays a fundamental role in its habitat acting as an ecosystem engineer. Over the last few centuries, African buffalo populations have declined because of range contraction and demographic decline caused by direct or indirect human activities. In Mozambique, historically home to large buffalo herds, the combined effect of colonialism and subsequent civil wars has created a critical situation that urgently needs to be addressed. In this study, we focused on the analysis of genetic diversity of Syncerus caffer caffer populations from six areas of Mozambique. Using genome-wide SNPs obtained from ddRAD sequencing, we examined the population structure across the country, estimated gene flow between areas under conservation management, including national reserves, and assessed the inbreeding coefficients. Our results indicate that all studied populations of Syncerus caffer caffer are genetically depauperate, with a high level of inbreeding. Moreover, buffaloes in Mozambique present a significant population differentiation between southern and central areas. We found an unexpected genotype in the Gorongosa National Park, where buffaloes experienced a dramatic population size reduction, that shares a common ancestry with southern populations of Catuane and Namaacha. This could suggest the past occurrence of a connection between southern and central Mozambique and that the observed population structuring could reflect recent events of anthropogenic origin. All the populations analysed showed high levels of homozygosity, likely due to extensive inbreeding over the last few decades, which could have increased the frequency of recessive deleterious alleles. Improving the resilience of Syncerus caffer caffer in Mozambique is essential for preserving the ecosystem integrity. The most viable approach appears to be facilitating translocations and re-establishing connectivity between isolated herds. However, our results also highlight the importance of assessing intraspecific genetic diversity when considering interventions aimed at enhancing population viability such as selecting suitable source populations.

Objective: To present the surgical technique and outcomes of robotic ureteral reimplantation in ileal conduit (IC) and neobladder (NB) in patients with prior minimally-invasive radical cystectomy and intracorporeal urinary diversion, who developed benign uretero-ileal anastomotic strictures. Patients and surgical procedure: We report on a multiinstitutional cohort of 10 patients (7 IC, 3 NB) who had 12 uretero-ileal strictures (8 unilateral, 2 bilateral) causing hydronephrosis and renal function deterioration, who underwent robotic uretero-ileal reimplantation in referral centers for robotic surgery between 2016 and 2022. Median age was 67.5 years (Interquartile range [IQR]: 66–69). The stricture was diagnosed at a median of 6 months (IQR 5–10) from the initial surgery. All unilateral strictures were on the left side. Two patients received unsuccessful endoscopic dilatation before the reconstructive surgery. All patients underwent nephrostomy placement prior to the reconstructive procedure. Robotic uretero-ileal reanastomosis started with adhesiolysis, followed by the identification of the ureters and urinary diversion, facilitated by the use of intracavitary saline or ICG. When dissecting the ureters, a „no touch” technique was used, in order to minimize devascularization and ischemia. Localization of the ureteral stricture was critical. The excision of the entire ischemic segment was performed until signs indicative of adequate tissue trophism were found. At the same time, consideration was given to spare sufficient length of the ureteral stumps to allow for a tension-free anastomosis. Direct anastomosis using monofilament resorbable suture, with insertion of mono J or double J stent was performed with both ileal conduit and neobladder. Bricker technique was used in case of unilateral stricture. Results: The median operative time for robotic uretero-ileal reanastomosis was 152 min (IQR 120–180) and the median blood loss was 50 ml (IQR 40–70). No intraoperative complications occurred according to the ICARUS criteria. Median length of hospital stay was 4.5 days (IQR 3–6). Two Clavien-DIndo II (20 %) postoperative complications were registered (urinary tract infection and acute kidney injury). No patients required readmission or reoperation. The mean length of ureteral catheterization for reimplantation in IC was 20.7 days (± 4.29). For patients with NB, the mean ureteral and urethral catheterization times were 54.3 days (± 22.8) and 19.3 days (± 11.08), respectively. The ureteral stents were removed in all patients. At a median of 16 months follow-up (range 6–36 months), 2 patients (one IC and one NB, respectively) had persistent hydronephrosis. Conclusion: In patients requiring surgery for benign ureteral strictures following cystectomy, robotic surgery allows for safe and efficient ureteral reimplantation in urinary diversion.

Mobile robotic technologies are emerging in agriculture in recent years, driven by labor shortages, the need of precision farm management, and the improvement of farmers' quality of life. Mobile robotic technologies, both aerial and ground, have been considered as one of the most important and promising solutions to address agricultural challenges. Nevertheless, the implementation rate in farms is still low. The aim of this study was to evaluate the performance of a mobile agricultural ground robot to assess its possible implementation in the farm environment. The mobility performances as well as the energy consumption of the mobile robot were evaluated considering different interaction systems (teleoperated, autonomous driving) and application areas (weeding, tilling). The results show that the forward speed of the tested mobile robot is affected by the towed load, up to 230 kg, and that the robot could be driven continuously for 2 h in the field without decreasing its performances at a maximum speed between 0.71–0.77 m s-1. The autonomy of the tested robot is limited, but this is mainly due to the battery technology used. The mobile robot effectively tow implements for weeding and tilling operations managing grass with a single pass (40 % weed removal) and improving soil bulk density. The average energy consumption across the different settings was about 1.43 kWh for each hour of use. Moreover, although the RTK-GNSS autonomous navigation used was a low-cost system, the results showed a good accuracy, which allowed the mobile robot to navigate autonomously in the 2 m inter-row of the vineyard. Finally, the working capacity of the mobile robots, considering the implements used, is on average 0.29 ha h-1. This study provides further evidence for the possible use of ground mobile robot in agriculture to carry out autonomous or semi-autonomous operations.

Objective: Since adalimumab approval in childhood chronic non-infectious uveitis (cNIU), the prognosis has been dramatically changed, but the 25 % failed to achieve inactivity. There is not accordance if it is better to switch to another anti-TNF or to swap to another category of biologic. Thus, we aim to summarize evidence regarding the best treatment of cNIU refractory to the first anti-TNF. Methods: A systematic literature review and meta-analysis, according to PRISMA Guidelines, was performed(Jan2000-Aug2023). Studies investigating the efficacy of treatment in cNIU refractory to the first anti-TNF were considered for inclusion. The primary outcome was the improvement of intraocular inflammation according to SUN. A combined estimation of the proportion of children responding to switch or swap and for each drug was performed. Results: 23 articles were eligible, reporting 150 children of whom 109 switched anti-TNF (45 adalimumab, 49 infliximab, 9 golimumab) and 41 swapped to another biologics (31 abatacept, 8 tocilizumab and 1 rituximab). The proportion of responding children was 46 %(95 % CI 23-70) for switch and 38 %(95 % CI 8-73) for swap (χ20.02, p = 0.86). Instead analysing for each drug, the proportion of responding children was the 24 %(95 % CI 2-55) for adalimumab, 43 %(95 % CI 2-80) for abatacept, 79 %(95 % CI 61-93) for infliximab, 56 %(95 % CI 14-95) for golimumab and 96 %(95 % CI 58-100) for tocilizumab. We evaluated a superiority of tocilizumab and infliximab compared to the other drugs(χ2 27.5 p

ABSTRACTAlthough the role of the intestinal microbiota in the pathogenesis of inflammatory bowel disease (IBD) is beyond debate, attempts to verify the causative role of IBD-associated dysbiosis have been limited to reports of promoting the disease in genetically susceptible mice or in chemically induced colitis. We aimed to further test the host response to fecal microbiome transplantation (FMT) from Crohn’s disease patients on mucosal homeostasis in ex-germ-free (xGF) mice. We characterized and transferred fecal microbiota from healthy patients and patients with defined Crohn’s ileocolitis (CD_L3) to germ-free mice and analyzed the resulting microbial and mucosal homeostasis by 16S profiling, shotgun metagenomics, histology, immunofluorescence (IF) and RNAseq analysis. We observed a markedly reduced engraftment of CD_L3 microbiome compared to healthy control microbiota. FMT from CD_L3 patients did not lead to ileitis but resulted in colitis with features consistent with CD: a discontinued pattern of colitis, more proximal colonic localization, enlarged isolated lymphoid follicles and/or tertiary lymphoid organ neogenesis, and a transcriptomic pattern consistent with epithelial reprograming and promotion of the Paneth cell-like signature in the proximal colon and immune dysregulation characteristic of CD. The observed inflammatory response was associated with persistently increased abundance of Ruminococcus gnavus, Erysipelatoclostridium ramosum, Faecalimonas umbilicate, Blautia hominis, Clostridium butyricum, and C. paraputrificum and unexpected growth of toxigenic C. difficile, which was below the detection level in the community used for inoculation. Our study provides the first evidence that the transfer of a dysbiotic community from CD patients can lead to spontaneous inflammatory changes in the colon of xGF mice and identifies a signature microbial community capable of promoting colonization of pathogenic and conditionally pathogenic bacteria.

IntroductionResearch to date has focused on the associations between spelling and (i) its precursors (phonological information processing and language) and (ii) socioeconomic status and bilingualism. Studies have also indicated that bilingualism and parental education are associated with spelling precursors. Whereas these associations have previously been analyzed individually, this study proposes a mediation model in which the effects of socioeconomic status and bilingualism on spelling are mediated by phonological information processing and language skills.MethodsA total of 1,012 German-speaking first graders attending primary schools in Austria were assessed at the beginning of the first grade on their phonological information processing and language abilities, and their spelling abilities were tested again at the end of the first grade. Subsequently, a structural equation modeling approach was employed to evaluate the mediation model.ResultsIn line with the mediation hypothesis, the results show indirect effects of parental education (as a measure of socioeconomic status) on spelling via language and phonological information processing. In addition to mediation, we also found a direct effect of SES on spelling performances. For bilingualism, the results support full mediation as an indirect effect via language abilities. Notably, we found no effect of bilingual status on phonological information processing.DiscussionThis study highlights the ongoing need for systematic oral language training for bilingual children and children from low-SES backgrounds that starts in preschool and continues throughout primary school. Moreover, given the predictive effect of phonological awareness on spelling achievement, phonological awareness should be part of the training for preschool and school-aged children.

Abstract Pharmacogenomic Polygenic Risk Scores (PRS) have emerged as a tool to address the polygenic nature of pharmacogenetic phenotypes, increasing the potential to predict drug response. Most pharmacogenomic PRS have been extrapolated from disease‐associated variants identified by genome wide association studies (GWAS), although some have begun to utilize genetic variants from pharmacogenomic GWAS. As pharmacogenomic PRS hold the promise of enabling precision medicine, including stratified treatment approaches, it is important to assess the opportunities and challenges presented by the current data. This assessment will help determine how pharmacogenomic PRS can be advanced and transitioned into clinical use. In this review, we present a summary of recent evidence, evaluate the current status, and identify several challenges that have impeded the progress of pharmacogenomic PRS. These challenges include the reliance on extrapolations from disease genetics and limitations inherent to pharmacogenomics research such as low sample sizes, phenotyping inconsistencies, among others. We finally propose recommendations to overcome the challenges and facilitate the clinical implementation. These recommendations include standardizing methodologies for phenotyping, enhancing collaborative efforts, developing new statistical methods to capitalize on drug‐specific genetic associations for PRS construction. Additional recommendations include enhancing the infrastructure that can integrate genomic data with clinical predictors, along with implementing user‐friendly clinical decision tools, and patient education. Ethical and regulatory considerations should address issues related to patient privacy, informed consent and safe use of PRS. Despite these challenges, ongoing research and large‐scale collaboration is likely to advance the field and realize the potential of pharmacogenomic PRS.

Major depressive disorder (MDD) is a heterogeneous syndrome, associated with different levels of severity and impairment on the personal functioning for each patient. Classification systems in psychiatry, including ICD-11 and DSM-5, are used by clinicians in order to simplify the complexity of clinical manifestations. In particular, the DSM-5 introduced specifiers, subtypes, severity ratings, and cross-cutting symptom assessments allowing clinicians to better describe the specific clinical features of each patient. However, the use of DSM-5 specifiers for major depressive disorder in ordinary clinical practice is quite heterogeneous.The present study, using a Delphi method, aims to evaluate the consensus of a representative group of expert psychiatrists on a series of statements regarding the clinical utility and relevance of DSM-5 specifiers for major depressive disorder in ordinary clinical practice. Experts reached an almost perfect agreement on statements related to the use and clinical utility of DSM-5 specifiers in ordinary clinical practice. In particular, a complete consensus was found regarding the clinical utility for ordinary clinical practice of using DSM-5 specifiers. The use of specifiers is considered a first step toward a “dimensional” approach to the diagnosis of mental disorders.

Abstract Background Health‐related quality of life (HRQL) is an important goal for patients with major depressive disorder (MDD), but whether antidepressants improve HRQL in these patients is unclear. Here, we describe the real‐world effects of trazodone once‐a‐day (TzOAD) and selective serotonin reuptake inhibitor (SSRI) treatments on HRQL and functioning in adults with MDD. Methods This 8‐week prospective, observational, open‐label, multicenter study was conducted in adults with moderate or severe MDD for whom TzOAD or SSRI were prescribed as monotherapy. The primary outcome was life enjoyment and satisfaction assessed via the patient‐reported Quality‐of‐Life Enjoyment and Satisfaction Questionnaire Short Form (Q‐LES‐Q‐SF) from baseline to week 8. Secondary outcomes included change in Q‐LES‐Q‐SF from baseline to weeks 1 and 2; severity of depressive symptoms using the Montgomery Åsberg Depression Rating Scale (MADRS) and sleep disturbance via the PROMIS SF‐SD 8b questionnaire at weeks 1, 2, and 8; and overall functioning via the Sheehan Disability Scale (SDS), hedonic capacity using the Snaith–Hamilton Pleasure Scale (SHAPS), and cognitive dysfunction using the Perceived Deficits Questionnaire (PDQ‐5) at baseline and week 8. Results The study included 208 adults with MDD (mean [SD] age = 50.2 [14.3] years; 68.6% female; 98.4% White). Life enjoyment and satisfaction improved from baseline to week 8 for both treatment groups: Q‐LES‐Q‐SF mean (SD) scores were 27.5 (20.4) for the SSRI group and 39.0 (22.1) for the TzOAD group. Depressive symptoms and sleep disturbances also reduced from baseline to week 8: MADRS (SSRI, −15.7 [8.3]; TzOAD, −21.0 [9.8]); PROMIS SF‐SD 8b (SSRI, −9.9 [12.6]; TzOAD, −22.0 [12.6]). Mean change scores in Q‐LES‐Q‐SF, MADRS, and PROMIS SF‐SD 8b improved as early as week 1 in both groups. Mean scores also improved from baseline to week 8 on SDS (SSRI, −9.2 [7.4]; TzOAD, −14.3 [7.5]), SHAPS (SSRI, −6.6 [4.3]; TzOAD, −8.3 [4.4]), and PDQ‐5 (SSRI, −5.8 [4.5]; TzOAD, −7.7 [5.0]). Conclusions In adults with MDD who received TzOAD or SSRIs, overall and individual HQRL domains improved rapidly and in parallel with improvements in depressive symptoms, with a slightly greater improvement observed in the TzOAD group.

IntroductionThis study comprehensively compared laparoscopic liver resection (LLR) to open liver resection (OLR) in treating colorectal cancer liver metastasis (CRLM).MethodsA systematic review of relevant literature was conducted to assess a range of crucial surgical and oncological outcomes.ResultsFindings indicate that minimally invasive surgery (MIS) did not significantly prolong the duration of surgery compared to open liver resection and notably demonstrated lower blood transfusion rates and reduced intraoperative blood loss. While some studies favored MIS for its lower complication rates, others did not establish a statistically significant difference. One study identified a lower post-operative mortality rate in the MIS group. Furthermore, MIS consistently correlated with shorter hospital stays, indicative of expedited post-operative recovery. Concerning oncological outcomes, while certain meta-analyses reported a lower rate of cancer recurrence in the MIS group, others found no significant disparity. Overall survival and disease-free survival remained comparable between the MIS and open liver resection groups.ConclusionThe analysis emphasizes the potential advantages of LLR in terms of surgical outcomes and aligns with existing literature findings in this field.Systematic review registration[website], identifier [registration number].

IntroductionExcessive daytime sleepiness (EDS) is a common and debilitating symptom in both forms of myotonic dystrophy (DM), significantly impacting patients’ quality of life. The review focuses on the purpose of examining the current understanding of EDS in these conditions, the difficulty in correctly accessing it, the recent findings related to its etiology and prevalence, and a summary of potential therapeutic implications.MethodsWe conducted a comprehensive search through PubMed, selecting studies that provided significant insights into the mechanisms, prevalence, and management of EDS in DM1 and DM2.Results and discussionEDS is highly prevalent in both DM1 and DM2. Polysomnographic studies have revealed prominent dysregulation of REM sleep in DM1, suggesting a possible narcoleptic-like phenotype and alterations in NREM sleep that contributes to daytime sleepiness. Other factors have been proposed to explain EDS in DM1, including dysregulation of the sleep-wake circadian rhythm through nocturnal actigraphy analysis. The central origin of EDS is increasingly delineated supported by serotonin and orexin pathways dysfunction, and recent neuroradiological findings showing that in DM1 hippocampus volume was positively correlated with self-reported fatigue and somnolence. Sleep-disordered breathing and respiratory dysfunctions are prevalent in DM, their direct correlation with EDS remains complex and inconclusive, but respiratory evaluation should be recommended if obstructive sleep apneas or respiratory muscle dysfunctions are suspected. Drug interventions, such as modafinil and mexiletine, have shown promise in managing excessive daytime sleepiness and reducing myotonia without significant cardiac conduction effects. Enhancing EDS management in myotonic dystrophy is key to improving overall patient well-being.

Chest pain is one of the most prevalent causes of Emergency Department (ED) admission and could be a presenting symptom of Acute Coronary Syndrome (ACS). The aim of this review was to provide an overview of the research about troponin and its limitations and new biomarkers used in patients with cardiovascular diseases, with a special focus on soluble Suppression of Tumorigenicity 2 (sST2) and Soluble Urokinase Plasminogen Activator Receptor (suPAR). In January 2024, a PubMed and Reviews in Cardiovascular Medicine (RCM) search was carried out to identify all relevant papers in the past five years. 80 articles were included in the final review. ssT2 and suPAR are involved in both acute and chronic cardiovascular disease and can predict the risk of adverse events. sST2 and suPAR are promising biomarkers that, in combination with troponin, could help in the management of patients with chest pain in the ED. Further studies are needed to validate their role in management of ACS in this specific setting.

BackgroundImage and Performance-Enhancing Drugs (IPEDs) can enhance mental and physical capabilities and impact one’s overall health. Initially confined in sport environments, IPEDs use has become increasingly widespread in a high-performing society. The present study was aimed at profiling IPEDs use during the COVID-19 lockdown among an international sample of young adults.MethodsA cross-sectional observational study was carried out in eight countries (United Kingdom, Italy, Lithuania, Hungary, Portugal, Spain, Brazil, and Japan) between April and May 2020. The survey questionnaire included validated measurements such as Exercise Addiction Inventory (EAI), Appearance Anxiety Inventory (AAI), and Self-Compassion Scale (SCS) as well as questions about the type of IPEDs, purchasing methods and socio-demographic information.ResultsA total of 736 IPEDs users were included in the survey. Their mean age was 33.05 years (±SD = 10.06), and 64.2% were female participants. Overall, 6.8% were found at risk of exercise addiction (EAI >24), 27.6% presented high levels of appearance anxiety, and 24.9% revealed low levels of emotional regulation’s self-compassion. Most participants (55.6%) purchased IPEDs through pharmacies/specialized shops, while 41.3% purchased IPEDs on the Internet. Online IPEDs buyers were mainly men who had higher scores on the Exercise Addiction Inventory. One or more IPEDs classifiable as “potentially risky” were used by 66.3% of the sample. Users of “potentially risky IPEDs” were younger and primarily men. They showed higher scores both on the Exercise Addiction Inventory and Appearance Anxiety Inventory.ConclusionThis study profiled users of IPEDs when the most restrictive COVID-19 lockdown policies were implemented in all the participating countries. More targeted post-COVID 19 prevention strategies should be implemented according to the emerged socio-demographic and psychopathological traits and cross-cultural differences emerged. Longitudinal studies will also be needed to determine the long-term effect of the COVID-19 lockdown on IPEDs consumption.
