Background and Aims: Probe-based confocal endomicroscopy (pCLE) allows real-time microscopic visualization of the intestinal mucosa surface layers. Despite remission achieved through anti-tumor necrosis factor or vedolizumab therapy, anomalies in the intestinal epithelial barrier are observed in inflammatory bowel disease (IBD) patients. Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors., Methods: The study involved 84 patients, 40 with IBD under biologic therapy for over 6 months and in endoscopic remission, and 44 without IBD or irritable bowel syndrome (IBS) undergoing colorectal screening colonoscopy. White light endoscopy and probe-based confocal laser endomicroscopy were performed in the ileum, right colon, transverse colon, left colon, and rectum. Demographic, clinical, biological, and morphological factors were examined., Results: pCLE revealed abnormalities in both non-IBD individuals and those with IBD in endoscopic remission, such as fluorescein leakage, blood vessel dilatation, and hypervascularization across all segments, as well as epithelial gaps in the ileum, and crypt dilatation in the colon. Comparing the two groups, IBD patients exhibited slightly more gaps in the ileum, increased fluorescein leakage in the transverse colon, and fewer vessel dilatation in the transverse colon. Abnormalities were more frequent in cases of hypertension (p = 0.03), dyslipidemia (p = 0.02), female gender (p = 0.02), selective serotonin reuptake inhibitor (p = 0.03), and family history of IBD (p = 0.04) or colorectal cancer (p = 0.03)., Conclusion: Confocal endomicroscopy abnormalities are present in both non-IBD individuals undergoing colorectal cancer screening colonoscopy as in those with IBD in endoscopic remission. Further research is needed to understand the pathophysiological mechanisms of these abnormalities and their clinical impact., (© 2025 The Author(s).

Purpose: To assess the influence of operator, tool, dental loupes, and tooth position on enamel loss and composite remnants after removal of composite attachments (CA) for orthodontic clear aligners. Procedure duration was also analyzed., Materials and Methods: Eight maxillary resin dental arches with four natural teeth were placed in the right posterior sector in dental simulators, and CA was realized. The dental arches were randomly distributed according to three experimental factors: operator (junior, senior), tool (tungsten carbide bur and silicone polisher, only silicone polishers), and use of dental loupes. Dental arches were scanned with 3D profilometry before and after CA removal to measure enamel surface height variation (ESHV), particularly enamel loss in the CA area. Digital microscopy was used to detect composite remnants., Results: The mean enamel loss was -22.7 ± 29.4 µm (range -132 to 0 µm). It was not significantly influenced by experimental factors or tooth position. Composite remnants were found in 34.4% of teeth, significantly more in senior than in junior operators (p = 0.038). They were more frequent with silicone polishers than with tungsten carbide burs (p = 0.0005) and were reduced using dental loupes (p = 0.0090). Junior operators worked faster than senior operators (p = 0.031), but the latter were quicker when using the dental loupes (p = 0.012)., Conclusion: Aligner CA removal induces enamel damage or leaves composite remnants on its surface. The presence of composite remnants is influenced by the type of tool and can be reduced by using dental loupes, which also lowers working time.

Background: Blood pressure (BP) control in haemodialysis (HD) patients is essential. Peri-dialytic BP levels do not accurately diagnose hypertension or predict the cardiovascular (CV) mortality., Methods: In this study, we recruited 43 adult patients who had been on chronic HD for ≥3 months. Seven-day home BP monitoring (HBPM) (values of Day1 discarded) and 44-h interdialytic ambulatory BP monitoring (iABPM) were performed. Pre- and post-dialysis BP levels were measured during the 6 dialysis sessions prior to iABPM. A 6-year follow-up was carried out to assess all-cause and CV mortality., Results: In patients considered as normotensive in pre-dialysis ( n  = 17), masked hypertension was found in 24% and 29% on the basis of iABPM and HBPM, respectively. Conversely, among hypertensive patients in pre-dialysis ( n  = 26), 'white-coat' hypertension was noted in 23% either by iABPM or HBPM. After a 6-year follow-up, 25 patients were deceased including 6 patients from CV causes. Day-time systolic BP measured by iABPM was associated with all-cause mortality in an adjusted model for age and gender ( p  = 0.045)., Conclusion: In chronic HD patients, 44-h iABPM and 6-day HBPM show a reliable concordance and help to re-classify ∼25% of cases miscategorised based on pre-dialysis measurements. Day-time systolic BP levels using iABPM were significantly associated with 6-year all-cause mortality.

Over the last 30 years, group-IV semiconductors have been intensely investigated in the quest for a fundamental direct bandgap semiconductor that could yield the last missing piece of the Si Photonics toolbox: a continuous-wave Si-based laser. Along this path, it has been demonstrated that the electronic band structure of the GeSn/SiGeSn heterostructures can be tuned into a direct bandgap quantum structure providing optical gain for lasing. In this paper, we present a versatile electrically pumped, continuous-wave laser emitting at a near-infrared wavelength of 2.32 µm with a low threshold current of 4 mA. It is based on a 6-periods SiGeSn/GeSn multiple quantum-well heterostructure. Operation of the micro-disk laser at liquid nitrogen temperature is possible by changing to pulsed operation and reducing the heat load. The demonstration of a continuous-wave, electrically pumped, all-group-IV laser is a major breakthrough towards a complete group-IV photonics technology platform., Competing Interests: Competing interests: The authors declare no competing interests., (© 2024.

Background: Mesenchymal stromal cells (MSC) have immunomodulatory and hematopoiesis-supporting properties that could potentially benefit hematopoietic stem cell (HSC) engraftment and decrease the incidence and/or severity of graft-versus-host disease (GVHD)., Methods: Based on our previous pilot study, we established a multicenter, prospective, randomized, double-blind trial evaluating the efficacy of co-infusing third-party MSC (1.5-3 × 10 6 /kg) versus placebo on the day of HSC transplantation (HCT) to prevent GVHD in recipients of HLA-mismatched unrelated donors after reduced-intensity conditioning., Results: The study planned to include 120 patients to improve 1-year overall survival (OS) from 55 to 77% but was stopped after 9 years for low recruitment (n = 38). One-year OS was 74% in the MSC group and 80% in the placebo group. In multivariate analysis, the incidence of grade II-IV acute GVHD was significantly lower in patients receiving MSC (HR 0.332, 95% CI 0.124-0.890, p = 0.0284). No difference was observed in the incidences of chronic GVHD, infection or relapse, overall or progression-free survival at 1 year or long-term, or hematopoietic and immune reconstitution., Conclusions: Despite premature study closure, the suggested beneficial effect of MSC co-transplantation for the prevention of acute GVHD in HLA-mismatched HCT warrants further investigation., Competing Interests: Declarations. Ethics approval and consent to participate: The protocol “Co-transplantation of mesenchymal stem cells and HLA-mismatched allogeneic hematopoietic cells after nonmyeloablative conditioning: a phase II randomized double-blind study” was approved centrally by the “Comité d’Ethique Hospitalo-Facultaire Universitaire de Liège” on 6 July 2010 (file 2010/16) as well as by the ethics committees of all participating centers and the study was conducted in accordance with the Declaration of Helsinki. Before participating in the study, all patients (or their legal representatives if minors) signed an informed consent form. Consent for publication: Not applicable.

This retrospective study including 93 patients who presented a new diagnosis of lung cancer at the University Hospital of Liege between January 2023 and April 2023 analyzed the prevalence of smoking cessation following the diagnosis announcement. It was also investigated whether certain factors influenced this rate (stage, histology, type of treatment received, tobacco monitoring,…) and whether the impact of this smoking cessation influenced the progression of the disease and the response to oncological treatments. The results show that 34.8 % of active smokers at diagnosis experienced smoking cessation at 6 months and 32.6 % at 1 year. This success rate of more than 30 % at 1 year is considerably higher than the success rates observed in individuals who attempt to obtain smoking cessation spontaneously and independently, outside of a cancer diagnosis (3-5 %). However, it remains low if one consider that smoking cessation is an important factor for increasing the survival rate for this type of cancer. It should be noted that, among the 51 smokers still active, 42 (82.4 %) did not consult a tobacco specialist. Smoking cessation support should in fact be offered to patients diagnosed with lung cancer more systematically and as early as possible in order to optimize the effectiveness of treatments and to increase the chances of survival.

Introduction: Artificial Intelligence (AI) is increasingly being integrated into anesthesiology to enhance patient safety, improve efficiency, and streamline various aspects of practice., Objective: This study aims to evaluate whether AI-generated images accurately depict the demographic racial and ethnic diversity observed in the Anesthesia workforce and to identify inherent social biases in these images., Methods: This cross-sectional analysis was conducted from January to February 2024. Demographic data were collected from the American Society of Anesthesiologists (ASA) and the European Society of Anesthesiology and Intensive Care (ESAIC). Two AI text-to-image models, ChatGPT DALL-E 2 and Midjourney, generated images of anesthesiologists across various subspecialties. Three independent reviewers assessed and categorized each image based on sex, race/ethnicity, age, and emotional traits., Results: A total of 1,200 images were analyzed. We found significant discrepancies between AI-generated images and actual demographic data. The models predominantly portrayed anesthesiologists as White, with ChatGPT DALL-E2 at 64.2% and Midjourney at 83.0%. Moreover, male gender was highly associated with White ethnicity by ChatGPT DALL-E2 (79.1%) and with non-White ethnicity by Midjourney (87%). Age distribution also varied significantly, with younger anesthesiologists underrepresented. The analysis also revealed predominant traits such as "masculine, ""attractive, "and "trustworthy" across various subspecialties., Conclusion: AI models exhibited notable biases in gender, race/ethnicity, and age representation, failing to reflect the actual diversity within the anesthesiologist workforce. These biases highlight the need for more diverse training datasets and strategies to mitigate bias in AI-generated images to ensure accurate and inclusive representations in the medical field., Competing Interests: OB received funding from the Harold Amos Medical Faculty Development Program and participated as an investigator for the clinical trial OLIVER from Medtronic®.

Background: Hyperglycemia and type 2 diabetes mellitus (T2DM) pose a significant risk for cardiovascular diseases and associated complications in individuals with hyperlipidemia. Statin therapy, effective in reducing cholesterol and cardiovascular risks, paradoxically increases incident T2DM risk due to its adverse impact on glucose homeostasis. Therefore, there is a pressing need for safe, and effective adjunctive or alternative therapies to manage hyperglycemia in hyperlipidemic individuals. There is growing body of pharmacological evidence suggesting that Amla and Olive extract supplementation can be beneficial in managing hyperglycemia in individuals with hyperlipidemia., Objective: The present study aimed to assess for the first time the potential synergistic antihyperglycemic effects of a daily co-supplementation of 1,000 mg Amla fruit and 50 mg Olive fruit standardized extracts (Cholesfytol NG ® ) over a 2-months period in hyperlipidemic adults with T2DM or prediabetes., Methods: This retrospective cross-sectional observational study analyzed treatment outcomes in 191 hyperlipidemic adults under the care of their physicians at 57 General Practitioner clinics in Belgium during real-life clinical practice between March 19, 2020, and January 31, 2022. These participants received Cholesfytol NG ® as supplementary therapy to improve their metabolic health. The supplement was prescribed in an open-label, non-randomized manner, tailored to each participant's need., Results: After 2-months of Cholesfytol NG ® supplementation, participants showed significant reductions in glycemia levels: in the T2DM group, levels decreased by 42.7 ± 17.9 mg/dL (27.9%, p  < 0.0001), and in the prediabetic group, by 2.26 ± 11.5 mg/dL (4.7%, p  = 0.0020). Conversely, no significant change was observed in participants with normal baseline glycemia (1.55 ± 10.3 mg/dL, p  = 0.088). Overall, glycemia levels decreased from 96.4 ± 18.2 mg/dL to 94.0 ± 13.5 mg/dL (mean decrease of 2.4 ± 14.5 mg/dL, p  < 0.0001). The supplement was well tolerated and no side-effects, serious adverse events, or treatment-emergent effects were reported., Conclusion: The findings of this real-life clinical study highlight the potential synergistic antihyperglycemic effects of co-supplementation with Amla and Olive fruit extracts in managing hyperglycemia, particularly in individuals with hyperlipidemia. These results suggest that this botanical combination may help mitigate risks associated with hyperglycemia and cardiovascular disease in hyperlipidemic population., Clinical Trial Registration: ClinicalTrials.gov, NCT06187298., Competing Interests: IJ and YD were employed by Laboratoire Tilman, Baillonville, Belgium.

Background: Mentorship is crucial to career advancement, medical education, and psychosocial support, especially for women and minorities. Although anesthesia mentoring programs have shown promise, there are no survey data regarding mentor-mentee relationship dynamics. This study aimed to explore the dynamics of the anesthesia mentor/mentee relationship., Methods: A open cross-sectional web-based survey was distributed by the European Society of Anesthesiology and Intensive Care and European Society of Regional Anesthesia to European anesthesiologists. Participation was anonymous and consent was obtained. The study evaluated responses relating to preferences, facilitators, and barriers to mentorship relationships along with sociodemographic information., Results: In total, 543 anesthesiologists responded to the survey, and 406 (111 mentees, 49 mentors, 193 both, 53 neither) responded to questions regarding mentorship. 184 anesthesiologists identified as woman and 22 as other genders (non-binary, transgender, gender-fluid, and self-described gender). Moreover, 250 anesthesiologists identified as white. Both mentors and mentees indicated that personal compatibility was the most important factor for successful mentorship. Barriers to mentorship included time consumption and perceived lack of interest from the mentor and mentee. Both mentors and mentees benefited from this relationship. The former reported feeling helpful, and the latter supported the development of clinical skills. The mentors indicated that their participation was important for protecting against burnout/exhaustion and impostor syndrome. Participants reported a preference for mentorship programs organized at the departmental level, offered at the start of the anesthesiology education curricula. Women were more likely to feel a 'lack of interest' in mentoring them as a barrier (OR = 2.49, P = 0.033). Gender was a barrier for mentors of other genders (OR = 23.9, P = 0.0027) and ethnicity (OR = 48.0, P = 0.0023). White mentees found gender (OR = 0.14, P = 0.021) and ethnicity (OR = 0.11, P = 0.048) to be less important barriers to successful mentorship relationship., Conclusion: When possible, programs should prioritize matching mentors and mentees based on personal compatibility and experience in the mentee's area of interest. Addressing the perceived lack of interest in mentoring is essential for promoting diversity, equality, and inclusion within anesthesiology, as well as and uplifting women and minorities., Trial Registration: Clinicaltrials.gov identifier: NCT05968339, First posted (01/08/2023)., (© 2024.

Resilience, the ability to bounce back from difficult events, is critical for an individual to negotiate stressors and adversity. Despite being widely studied, little is known about the processes involved in the development of resilience. The goal of the studies are to investigate the relationship between motivation orientation, emotional intelligence, cognitive appraisals, and psychological resilience. Two studies, using self-report questionnaires were conducted with employed young adults also enrolled in post-secondary studies (pre- and during the pandemic) to test the tenability of our proposed models. Study 1 and Study 2 showed that emotional intelligence and challenge appraisals were mediators of autonomous motivation and resilience. Study 2 revealed statistically significant differences in mean scores of autonomous motivation and emotional intelligence between non-pandemic students and pandemic students. Based on the findings, it is suggested that autonomous motivation, emotional intelligence, and challenge appraisals are important aptitudes for the development of resilience. Furthermore, findings suggest that social isolation caused by the pandemic may have affected levels of emotional intelligence. Ultimately, the research expands the literature on both self-determination theory and resilience by offering a unique multiple mediation model for predicting the development of resilience within the employed undergraduate population., (© 2024 The Authors.

Background and Aims: In 2009, the Institute of Medicine (IOM) issued recommendations for gestational weight gain (GWG) based on body mass index (BMI). Several studies have challenged those recommendations for women with obesity, considering them too liberal and advising more limited weight gain - or even weight loss - during pregnancy to improve maternal and neonatal outcomes. Our aim was to study how gestational weight gain in women with obesity impacted maternal and fetal complications in the Belgian population. We did this by comparing the results from two groups of patients with obesity: those who met the 2009 IOM standards and those who satisfied the stricter recommendations suggested by other authors., Materials and Methods: This is a retrospective cohort study using data collected at the Centre d'Epidémiologie Périnatale (CEpiP) from obese (BMI ≥ 30 kg/m 2 ) pregnant women with live singleton deliveries between 2010 and 2019 in Wallonia-Brussels Federation (n = 65,314)., Results: Compared to obese patients whose GWG satisfied the IOM standards, those with GWG meeting the stricter recommendations had lower rates of gestational hypertension (7.1 % vs. 10.1 %; p = 0.0059), cesarean section (22.1 % vs. 26.3 %; p = 0.0074), and macrosomia (12.0 % vs. 17.7 %; p < 0.0001). There was no significant difference in the rate of preterm delivery (6.9 % vs 5.8 %; p = 0.12) or small-for-gestational-age births (7.2 % vs. 6.2 %; p = 0.16)., Conclusion: Gestational weight gain below that currently recommended by the IOM appears beneficial to the health of mothers with obesity and their children. These data, from our population, further challenge the standards proposed since 2009., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Introduction: Attention to work addiction risk is growing; however, more studies are needed to explore the possible impact of work addiction risk on various aspects of employees' work and life domains. Although several studies have considered the antecedents or consequences of work addiction risk, this study particularly focuses on sleep quality as a potential explanatory underlying mechanism in the relation between work addition risk and three outcome variables including stress at home, stress at work and well-being., Method: The data was collected using an online platform and participants consisted of 188 French employees who were selected using simple random sampling method. Participants responded to the survey including the Work Addiction Risk Test (WART), stress at work, well-being, and sleep quality. The data was analyzed using JASP and SPSS-26 programs., Results: The results revealed that there are significant positive relationships between work addiction risk and both stress at home and at work and negative relationships between work addiction risk and both sleep quality and well-being. In addition, the analyses of the mediation paths suggest the significant mediation role of sleep quality for the link between work addition risk and stress at work as well as the link between work addiction risk and well-being., Discussion: Given the verified mediating role of sleep quality in the relationship between work addiction, stress and wellbeing, it is recommended that organizations and companies pay particular attention to their employees' sleep quality., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Charkhabi, Firoozabadi, Seidel, Habibi Asgarabad, De Paola and Dutheil.)

Background: Diabetes has a protective effect on abdominal aortic aneurysms (AAAs); however, there are contrasting reports on the impact of diabetes on endovascular aortic repair (EVAR) outcomes, endoleaks (ELs) being the major negative outcome. The present study characterizes ELs and their outcomes in AAA patients, diabetic or not. Methods: This single-center, retrospective, comparative study was carried out on 324 AAA patients who underwent elective EVARs between 2007 and 2016 at the University Hospital of Liège (Belgium). The primary endpoint was the incidence and effect of ELs on the evolution of the aneurysmal sac; the secondary endpoints were surgical reintervention and mortality rate. Diabetic and non-diabetic patients were compared with respect to various risk factors by logistic regression, while a Cox regression was used to analyze survival. Results: In AAA patients meeting the inclusion criteria (n = 248), 23% were diabetic. EL incidence was comparable ( p = 0.74) in diabetic (38.7%) vs. non-diabetic (43.9%) patients. EL risk factors were age (HR = 1.04, p = 0.014) and fibrate intake (HR = 3.12, p = 0.043). A significant association was observed between ELs and aneurysm sac enlargement ( p < 0.001), regardless of group ( p = 0.46). Aneurysm sac regression per month for non-diabetic patients was -0.24 ± 0.013, while for diabetics it was -0.18 ± 0.027 ( p = 0.059). Dyslipidemia (HR = 3.01, p = 0.0060) and sulfonylureas (HR = 8.43, p = 0.043) were associated with shorter EL duration, while diabetes (HR = 0.080, p = 0.038) and beta blockers (HR = 0.46, p = 0.036) were associated with longer EL duration. The likelihood of reoperation decreased with more recent surgery (OR = 0.90, p = 0.040), regardless of diabetic status. All-cause mortality was higher for the non-diabetic group (45.5% vs. 26.3%, p = 0.0096). Conclusions: Endoleak occurrence is a known risk factor for sac expansion. In diabetic patients, endoleaks lasted longer, and regression of the aneurysm sac tended to be slower. The number and type of reintervention was not related to the diabetic status of AAA patients, but overall survival was higher in patients with diabetes.

The world's oceans are challenged by climate change linked warming with typically highly populated coastal areas being particularly susceptible to these effects. Many studies of climate change on the marine environment use large, short-term temperature manipulations that neglect factors such as long-term adaptation and seasonal cycles. In this study, a Baltic Sea 'heated' bay influenced by thermal discharge since the 1970s from a nuclear reactor (in relation to an unaffected nearby 'control' bay) was used to investigate how elevated temperature impacts surface water microbial communities and activities. 16S rRNA gene amplicon based microbial diversity and population structure showed no difference in alpha diversity in surface water microbial communities, while the beta diversity showed a dissimilarity between the bays. Amplicon sequencing variant relative abundances between the bays showed statistically higher values for, e.g., Ilumatobacteraceae and Burkholderiaceae in the heated and control bays, respectively. RNA transcript-derived activities followed a similar pattern in alpha and beta diversity with no effect on Shannon's H diversity but a significant difference in the beta diversity between the bays. The RNA data further showed more elevated transcript counts assigned to stress related genes in the heated bay that included heat shock protein genes dnaKJ , the co-chaperonin groS , and the nucleotide exchange factor heat shock protein grpE . The RNA data also showed elevated oxidative phosphorylation transcripts in the heated (e.g., atpHG ) compared to control (e.g., atpAEFB ) bay. Furthermore, genes related to photosynthesis had generally higher transcript numbers in the control bay, such as photosystem I ( psaAC ) and II genes ( psbABCEH ). These increased stress gene responses in the heated bay will likely have additional cascading effects on marine carbon cycling and ecosystem services., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Seidel, Broman, Ståhle, Bergström, Forsman, Hylander, Ketzer and Dopson.)

Background: Identifying remission is of high importance in rheumatoid arthritis (RA) because remission is associated with less structural progression. We investigated the efficacy of a new optical imaging device, HandScan, to identify RA remission, as defined by ultrasound (US)., Methods: 61 RA patients were included. Disease activity was evaluated by clinical assessment and US, using gray-scale (GS) and Power Doppler (PD). HandScan determined unitary optical spectral transmission (OST) values for wrists, metacarpophalangeal and proximal interphalangeal joints. At the patient level, three composite HandScan (HS) scores were calculated: total HS score; disease activity score OST (DAS-OST) and DAS-OST without patient global assessment (PtGA). Using ROC curves, we determined HS cut-offs to identify US-defined remission., Results: At the joint level, unitary OST values significantly correlated with GS synovitis [odds ratio (OR) 2.43, p < 0.0001] and PD positivity (OR 3.72, p = 0.0002 ). At the patient level, total HS score and DAS-OST were significantly associated with all gray-scale US (GSUS) and power doppler US (PDUS) parameters evaluated (synovitis number and grade, synovial thickness, PD grade) (p < 0.05). The cut-off to identify US-defined remission at the joint level was of 0.92, giving an 81% sensitivity and a 96% positive predictive value (PPV). At the patient level, ROC-curves failed to identify a robust cut-off for the total HS score, but did identify a cut-off (3.68) for DAS-OST to identify US-defined remission, but with lower sensitivity (75%), specificity (56%) and PPV (67%)., Conclusions: HandScan is a non-invasive optical imaging technique providing OST values that correlate with GSUS and PDUS parameters. In addition, HandScan is able to reliably identify US-defined remission in RA at the joint level, with a good sensitivity and high PPV. At the patient level, HandScan DAS-OST can also determine US remission (while total HS score failed to do so), but with lower performance., (© 2024. The Author(s).)

Due to connectivity and automation trends, the medical device industry is experiencing increased demand for safety and security mechanisms. Anomaly detection has proven to be a valuable approach for ensuring safety and security in other industries, such as automotive or IT. Medical devices must operate across a wide range of values due to variations in patient anthropometric data, making anomaly detection based on a simple threshold for signal deviations impractical. For example, surgical robots directly contacting the patient's tissue require precise sensor data. However, since the deformation of the patient's body during interaction or movement is highly dependent on body mass, it is impossible to define a single threshold for implausible sensor data that applies to all patients. This also involves statistical methods, such as Z-score, that consider standard deviation. Even pure machine learning algorithms cannot be expected to provide the required accuracy simply due to the lack of available training data. This paper proposes using hybrid filters by combining dynamic system models based on expert knowledge and data-based models for anomaly detection in an operating room scenario. This approach can improve detection performance and explainability while reducing the computing resources needed on embedded devices, enabling a distributed approach to anomaly detection.

Background: While the efficacy of tofacitinib to induce and maintain clinical and endoscopic remission is well established in ulcerative colitis (UC), little is known about its efficacy to induce histological remission., Methods: We conducted a retrospective multicentric cohort study. UC patients ≥ 16 years treated by tofacitinib in whom histological activity has been evaluated before and after induction were eligible. The primary endpoint was the histological remission at the end of induction, assessed by the Nancy index and the epithelial neutrophilic infiltrate., Results: A total of 42 patients with UC (93% previously exposed to an anti-TNF and 81% to vedolizumab) were included between July 2018 and April 2022 and were followed for a median duration of 84 weeks [IQR, 35-134]. At the end of induction period (whether prolonged or not), 19% and 24% of patients achieved histological remission, using the Nancy index and the epithelial neutrophilic infiltrate, respectively. Survival without tofacitinib discontinuation was significantly longer in patients without epithelial neutrophilic infiltrate at the end of induction (whether prolonged or not) compared with patients with epithelial neutrophilic infiltrate (p = 0.036)., Conclusion: Tofacitinib induced histological remission in one fifth to one quarter of patients with UC who have previously failed anti-TNF or/and vedolizumab after induction (whether prolonged or not)., Competing Interests: Conflict of interests S Vieujean lecture and/or consulting fees from Abbvie, Ferring, Janssen, Takeda.

Climate change related warming is a serious environmental problem attributed to anthropogenic activities, causing ocean water temperatures to rise in the coastal marine ecosystem since the last century. This particularly affects benthic microbial communities, which are crucial for biogeochemical cycles. While bacterial communities have received considerable scientific attention, the benthic eukaryotic community response to climate change remains relatively overlooked. In this study, sediments were sampled from a heated (average 5°C increase over the whole year for over 50 years) and a control (contemporary conditions) Baltic Sea bay during four different seasons across a year. RNA transcript counts were then used to investigate eukaryotic community changes under long-term warming. The composition of active species in the heated and control bay sediment eukaryotic communities differed, which was mainly attributed to salinity and temperature. The family level RNA transcript alpha diversity in the heated bay was higher during May but lower in November, compared with the control bay, suggesting altered seasonal activity patterns and dynamics. In addition, structures of the active eukaryotic communities varied between the two bays during the same season. Hence, this study revealed that long-term warming can change seasonality in eukaryotic diversity patterns. Relative abundances and transcript expression comparisons between bays suggested that some taxa that now have lower mRNA transcripts numbers could be favored by future warming. Furthermore, long-term warming can lead to a more active metabolism in these communities throughout the year, such as higher transcript numbers associated with diatom energy production and protein synthesis in the heated bay during winter. In all, these data can help predict how future global warming will affect the ecology and metabolism of eukaryotic community in coastal sediments., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Li, Nilsson, Seidel, Ketzer, Forsman, Dopson and Hylander.)

Background: The inactive dephosphorylated and uncarboxylated form of the matrix Gla protein (dp-ucMGP) has been shown to be increased in plasma of inflammatory bowel disease (IBD) patients. Our aim was to assess if the plasmatic level of dp-ucMGP could reflect disease endoscopic activity, presence of strictures and cumulative structural bowel damage in Crohn's disease (CD) patients., Methods: The plasmatic level of dp-ucMGP was measured in a monocentric cohort of prospectively recruited patients. The analysis was done by chemiluminescent immunoassay on blood samples collected the day of a planned ileocolonoscopy. In addition to classical clinical data (gender, age, body mass index (BMI), disease duration, current treatment), endoscopic data (disease location, Crohn's Disease Endoscopic Index of Severity (CDEIS), mucosal healing (MH), presence of 9 CD lesion types) and biological markers (faecal calprotectin and C-reactive protein (CRP)) were collected. The association between dp-ucMGP level and Lémann index was also investigated. Univariate linear regression was used to investigate the relationship between dp-ucMGP level and different parameters collected., Results: A total of 82 ileocolonoscopies and dp-ucMGP assays were performed in 75 CD patients (45 females; 37 ileocolonic, 19 ileal and 19 colonic diseases) between October 2012 and November 2019. A total of 24 patients (29.3%) showed MH. The dp-ucMGP levels were not associated with MH, CDEIS, faecal calprotectin or CRP levels. Plasmatic dp-ucMGP levels increased significantly with age ( p  = 0.0032), disease duration ( p  = 0.0033), corticosteroids use ( p  = 0.019) and tended to increase in patients with intestinal strictures ( p  = 0.086) but not with the Lémann index., Conclusion: The significant increase of plasmatic dp-ucMGP levels with age, disease duration and the trend observed in patients with non-ulcerated strictures may suggest that this extracellular matrix protein could be a marker of tissue remodelling and physiological ageing of the gut.

Purpose: To assess two types of abutment materials routinely used in daily practice-direct polymethyl methacrylate (PMMA) and a zirconia-on-Ti-base abutment-and their effects on peri-implant soft tissues and bone remodeling in a minipig model., Materials and Methods: A total of 40 implants were placed in five minipigs in a single-stage surgery. Four different types of abutment materials (n = 10 per group) were used: (1) titanium (control); (2) zirconia (control); (3) PMMA (test 1); and (4) Ti-base (zirconia bonded to a titanium framework; test 2). After 3 months of healing, the samples were collected and subjected to nondecalcified histology. The soft tissue dimensions (sulcus, junctional epithelium, and connective tissue attachment) were assessed on each abutment mesially and distally, and the distance from the implant margin to the first bone-to-implant contact (BIC) was measured., Results: No statistically significant differences were found among the four groups regarding soft tissue dimensions (P = .21), and a long junctional epithelium (mean: 4.1 mm) and a short connective tissue attachment (mean: 0.3 mm) were found in the majority of abutments. In some samples, the junctional epithelium extended all the way to the bone level. The measured peri-implant bone remodeling was similar in all four groups (P = .25)., Conclusions: The present findings indicate that both direct PMMA and zirconia-on-Ti-base abutments seem to allow soft tissue integration similar to that of titanium and zirconia abutments. However, clinical studies are warranted to either confirm or refute the observed findings and to further investigate the influence of different materials on mucointegration.

Background: Hyperlipidemia is associated with a higher rate of cardiovascular, cerebrovascular, and peripheral vascular disease. Conventional drugs such as statins are effective in controlling hyperlipidemia; however, they are associated with various side effects, especially myalgia. Nutraceutical lipid-lowering interventions are becoming increasingly popular, particularly among patients who are intolerant or refractory to statins. Substantial preclinical and clinical evidence suggests that extracts of amla, walnut, and olive, and red yeast rice (RYR) powder possess significant antihyperlipidemic effects. Aims: This study aimed to evaluate the efficacy, safety, and patient satisfaction of a combined supplementation of standardized dry extracts of amla fruit (500 mg), walnut leaves (50 mg), olive fruit (25 mg), and RYR powder (33.6 mg) (Cholesfytol NG®) in hypercholesterolemic patients. Methods: This was a real-life setting , retrospective, observational, single-arm, non-randomized study in hypercholesterolemic patients (total cholesterol (TC) ≥ 200 mg/dL or low-density lipoprotein-cholesterol (LDL-C) ≥ 130 mg/dL), enrolled at 57 general practitioner (GP) surgeries in Belgium from March 2020 to January 2022. These patients received a GP-prescribed daily single dosage of two oral tablets of Cholesfytol NG® supplementation for 2 months to overcome their hypercholesterolemia in the absence of a conventional lipid-lowering drug (n = 208) or with a lipid-lowering drug (n = 13). At 2-month follow-up, the lipid profile was re-evaluated, alongside a patient's questionnaire on treatment general satisfaction and willingness to pursue supplementation. Results: After supplementation, TC decreased by 15%, LDL-C by 19%, non-high-density lipoprotein-cholesterol (non-HDL-C) by 20% (all p < 0.0001), triglycerides (TG) by 9% ( p = 0.0028) (-18.4%, p = 0.0042, in patients with baseline TG > 180 mg/dL, n = 58), and remnant cholesterol (RC) by 12% ( p = 0.0001). These changes were unaffected by statin intolerance status in patients who received Cholesfytol NG® alongside statin. The supplement was well tolerated by all patients, and no serious adverse events or supplement-emergent effects were reported. Most patients were satisfied with the supplementation and wanted to pursue the nutraceutical. Conclusion: According to the results of this study, a combined supplementation of amla, walnut, and olive extracts, and RYR powder exerts a significant antihyperlipidemic effect, leading to a decrease in circulatory LDL-C and RC levels in patients with hypercholesterolemia. The supplementation bears excellent safety and tolerability, and is rated as satisfactory and pursuable, even among patients with statin intolerance.

Background: Randomised controlled trials have shown that benralizumab, an anti-interleukin-5 receptor monoclonal antibody, reduces exacerbations and oral corticosteroid dose and improves asthma control and lung function in severe eosinophilic asthma. The aim of this study was to confirm results of randomised controlled trials in real life in a population of 73 patients with severe eosinophilic asthma treated with benralizumab for at least 12 months., Methods: Patients underwent careful monitoring of asthma exacerbations, exhaled nitric oxide fraction, lung function, asthma control and quality of life questionnaire responses and sputum induction, and gave a blood sample at baseline, after 6 months and then every year., Results: We found significant reductions in exacerbations (by 92%, p<0.0001) and oral corticosteroid dose (by 83%, p<0.001) after 6 months that were maintained over time, with 78% of patients able to stop oral corticosteroid therapy. Patients improved their Asthma Control Test (ACT) score (from 11.7±5.1 to 16.9±5.35, p<0.0001), Asthma Control Questionnaire (ACQ) score (from 2.88±1.26 to 1.77±1.32, p<0.0001) and Asthma Quality of Life Questionnaire score (+1.04, p<0.0001) at 6 months and this was maintained during follow-up. Only 35% and 43% of patients reached asthma control according to an ACT score ≥20 and ACQ score <1.5, respectively. We observed stable post-bronchodilation lung function over time and a significant reduction in sputum eosinophil count, with 85% of patients exhibiting sputum eosinophil counts <3% after 6 months (p<0.01) with no effect on exhaled nitric oxide fraction., Conclusion: In our real-life study, we confirm the results published in randomised controlled trials showing a sharp reduction in exacerbations and oral corticosteroid therapy, an improvement in asthma control and quality of life, and a dramatic reduction in sputum eosinophil count., Competing Interests: Conflict of interest: F.

Background and Objective: The aim of this retrospective cohort study is to evaluate the impact of assisted reproductive treatment (ART) on adverse maternal outcomes and the rate of hospitalization in maternal intensive care (MIC) in a tertiary university center in Liege, Belgium. Materials and Methods: This is a retrospective cohort study comparing two groups, 6557 patients who achieved pregnancy spontaneously and 330 patients who achieved pregnancy after ART, between January 2020 and December 2022. These patients were followed in the academic obstetrics department of Citadelle Hospital, Liège. The database of the ART center was compared with the database of the delivery unit to determine the cohort of patients who conceived after ART. Adverse maternal outcomes and MIC hospitalization rates were compared with between spontaneous pregnancies and ART groups. ART groups were also compared with each other. Results: The rate of hospitalization in maternal intensive care for patients who achieved pregnancy spontaneously was 12.1%, compared to 17.3% after ART. Comparing the rate of pre-eclampsia, 3.5% of spontaneous pregnancies were complicated by pre-eclampsia, while after ART, 10.9% of patients developed this complication during pregnancy. This rate was higher after IVF (12%) compared to intrauterine insemination and particularly after frozen embryo transfer (FET) in artificial cycle (17.9%). The birthweight of newborns after ART was also analyzed. A significant difference was obtained when comparing fresh embryo transfer with FET. Conclusions: Our study confirmed that FET in artificial cycle is a risk factor for pre-eclampsia and that fresh embryo transfer is associated with a higher rate of newborns with a lower percentile of birthweight. Our data showed that the rate of MIC hospitalization was significantly higher after ART but did not differ between groups.

Importance: Pseudomonas aeruginosa is an important pathogen often associated with hospital-acquired infections and chronic lung infections in people with cystic fibrosis. P. aeruginosa possesses a wide array of intrinsic and adaptive mechanisms of antibiotic resistance, and the regulation of these mechanisms is complex. Label-free quantitative proteomics is a powerful tool to compare susceptible and resistant strains of bacteria and their responses to antibiotic treatments. Here we compare the proteomes of three isolates of P. aeruginosa with different antibiotic resistance profiles in response to five challenge conditions. We uncover unique and shared proteome changes for the widely used laboratory strain PAO1 and two isolates of the Liverpool epidemic strain of P. aeruginosa , LESlike1 and LESB58. Our data set provides insight into antibiotic resistance in clinically relevant Pseudomonas isolates and highlights proteins, including those with uncharacterized functions, which can be further investigated for their role in adaptive responses to antibiotic treatments., Competing Interests: The authors declare no conflict of interest.
