Context. We carried out a long-term campaign spanning 17 year to obtain high-precision radial velocities (RVs) with the HARPS spectrograph for a large sample of evolved stars in open clusters.
Aims. The aim of this work is to search for planets around evolved stars, with a special focus on stars more massive than 2 M⊙ in light of previous findings that show a drop in planet occurrence around stars above this mass.
Methods. We used kima – a package for Bayesian modelling of RV and activity data with Gaussian process capability and Nested sampling for model comparison – to find the Keplerian orbits most capable of explaining the periodic signals observed in RV data, which have semiamplitudes of between 75 and 500 m s−1. We also studied the variation of stellar activity indicators and photometry in order to discard stellar signals mimicking the presence of planets.
Results. We present a planet candidate in the open cluster NGC 3680 that orbits the 1.64 M⊙ star No. 41. The planet has a minimum mass of 5.13 MJ and a period of 1155 days. We also present periodic and large-amplitude RV signals of probable stellar origin in two more massive stars (5.84 and 3.05 M⊙ in the clusters NGC 2345 and NGC 3532). Finally, using new data, we revise the RV signals of the three stars analysed in our previous paper. We confirm the stellar origin of the signals observed in NGC 2423 No. 3 and NGC 4349 No. 127. On the other hand, the new data collected for IC4651 No. 9122 (1.79 M⊙) seem to support the presence of a bona fide planet of 6.22 MJ at a period of 744 days, although more data will be needed to discard a possible correlation with the CCF-FWHM.
Conclusions. The targets presented in this work showcase the difficulties in interpreting RV data for evolved massive stars. The use of several activity indicators (CCF-FWHM, CCF-BIS, Hα), photometry, and long-term observations (covering several orbital and stellar rotational periods) is required to discern the true nature of the signals. However, in some cases, all this information is insufficient, and the inclusion of additional data – such as the determination of magnetic field variability or RV points in the near-infrared – will be necessary to identify the nature of the discovered signals.

Context.The Doppler shift predicted by general relativity for light escaping a gravitational potential has been observed on Earth as well as in the direction of various stars and galaxy clusters at optical wavelengths.Aims.Observing the gravitational redshift in the X-ray band within galaxy clusters could provide information on their properties and, in particular, their gravitational potential. We present a feasibility study of such a measurement, using the capabilities of the next-generation European X-ray observatoryAthena.Methods.We used a simple generalized Navarro–Frenk–White potential model along with aβ-model for the density of baryonic matter, which sets the emission to provide an estimation of the observed redshift in the simplest of cases. We generated mock observations with theAthenaX-ray Integral Field Unit (X-IFU) for a nearby massive cluster, while seeking to recover the gravitational redshift along with other properties of the toy model cluster.Results.We investigated the observability of the gravitational redshift in an idealized test case of a nearby massive cluster with theAthenaX-IFU instrument, as well as its use in probing the properties of the potential well. We were also able to constrain the mass to a ∼20% level of precision and the cosmological redshift to less than ∼1%, within a simplified and idealized observational framework. More refined simulations accounting for further effects such as the internal gas motions and the actual shape of the potential well are required to fully investigate the feasibility of measuring the gravitational redshift for a single target or statistically over a sample of galaxy clusters.
Estimation of Colloid Osmotic Pressure During Hemodilutional Cardiopulmonary Bypass
Authors: Beshere George A. , Camerlengo Leon J. , Dearing James P. 
Published: September 2023

Patients undergoing cardiopulmonary bypass (CPB) using hemodilution are subjected to large reductions in colloid osmotic pressure (COP). The purpose of this investigation was to determine the course of COP during CPB and to compare these values to critical ranges for COP as cited in the literature.
The prime consisted of a mixture of the crystalloid (Lactated Ringer’s) and a variety of colloids. Samples were taken of the prime, and blood drawn prior to, during, and after CPB. The COP of each sample was measured, and also estimated by three (3) different techniques.
During CPB, patient’s COP were reduced by 30–60%, placing them within the published critical ranges for COP. Since patients did not suffer the predicted consequences of large reductions in COP, it is apparent the previously accepted critical ranges for COP must be re-evaluated for the CPB patient.
In the process of this investigation, a simple pumpside method for COP estimations was developed.

Abstract
Background and study aims Because of concerns about peri-procedural adverse events (AEs), guidelines recommend anesthetist-managed sedation (AMS) for long and complex endoscopic procedures. The safety and efficacy of physician-administered balanced sedation (PA-BS) for endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (LNPCPs) ≥20 mm is unknown.
Patients and methods We compared PA-BS with AMS in a retrospective study of prospectively collected data from consecutive patients referred for management of LNPCPs (NCT01368289; NCT02000141). A per-patient propensity analysis was performed following a 1:2 nearest-neighbor (Greedy-type) match, based on age, gender, Charlson comorbidity index, and lesion size. The primary outcome was any peri-procedural AE, which included hypotension, hypertension, tachycardia, bradycardia, hypoxia, and new arrhythmia. Secondary outcomes were unplanned admissions, 28-day re-presentation, technical success, and recurrence.
Results Between January 2016 and June 2020, 700 patients
underwent EMR for LNPCPs, of whom 638 received PA-BS. Among them, the median age was 70 years
(interquartile range [IQR] 62–76 years), size 35 mm (IQR 25–45 mm), and duration 35 minutes
(IQR 25–60 minutes). Peri-procedural AEs occurred in 149 (23.4%), most commonly bradycardia
(116; 18.2%). Only five (0.8%) required an unplanned sedation-related admission due to AEs (2
hypotension, 1 arrhythmia, 1 bradycardia, 1 hypoxia), with a median inpatient stay of 1 day
(IQR 1–3 days). After propensity-score matching, there were no differences between PA-BS and
AMS in peri-procedural AEs, unplanned admissions, 28-day re-presentation rates, technical
success or recurrence.
Conclusions Physician-administered balanced sedation for the EMR of LNPCPs is safe. Peri-procedural AEs are infrequent, transient, rarely require admission (<1%), and are experienced in similar frequencies to those receiving anesthetist-managed sedation.

Abstract
Background and study aims Gut infection is common during acute COVID-19, and persistent SARS-CoV-2 gut infection has been reported months after the initial infection, potentially linked to long-COVID syndrome. This study tested the incidence of persistent gut infection in patients with a history of COVID-19 undergoing endoscopic examination.
Patients and methods Endoscopic biopsies were prospectively collected from patients with previous COVID-19 infection undergoing upper or lower gastrointestinal endoscopy (UGE or LGE). Immunohistochemistry was used to detect the presence of persistent SARS-CoV-2 nucleocapsid proteins.
Results A total of 166 UGEs and 83 LGE were analyzed. No significant differences were observed between patients with positive and negative immunostaining regarding the number of previous COVID-19 infections, time since the last infection, symptoms, or vaccination status. The incidence of positive immunostaining was significantly higher in UGE biopsies than in LGE biopsies (37.34% vs. 16.87%, P=0.002). Smokers showed a significantly higher incidence of positive immunostaining in the overall cohort and UGE and LGE subgroups (P <0.001). Diabetic patients exhibited a significantly higher incidence in the overall cohort (P=0.002) and UGE subgroup (P=0.022), with a similar trend observed in the LGE subgroup (P=0.055).
Conclusions Gut mucosal tissues can act as a long-term reservoir for SARS-CoV-2, retaining viral particles for months following the primary COVID-19 infection. Smokers and individuals with diabetes may be at an increased risk of persistent viral gut infection. These findings provide insights into the dynamics of SARS-CoV-2 infection in the gut and have implications for further research.

Abstract
Introduction The Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale was developed to evaluate the safety, efficiency, and overall pharyngeal swallowing performance in patients with dysphagia (DIGESTs, DIGESTe, and DIGESTt, respectively). Although various types of swallowing dysfunction are encountered in children with esophageal atresia (EA), oropharyngeal dysphagia poses risk for aspiration. Therefore, a retrospective study was performed to evaluate the safety and efficacy of swallowing by using DIGEST score in children with EA.
Patients and Methods Thirty-nine EA patients were included. The demographic features, respiratory problems, results, and outcomes of surgical treatment were evaluated from medical records. The videofluoroscopic swallowing evaluation investigated for both airway protection and bolus residuals at the level of vallecula, posterior pharyngeal wall, and pyriform sinus at liquid and pudding consistencies. The penetration and aspiration scale (PAS) was used to define penetration and aspiration severity, and DIGEST was used to evaluate DIGESTs, DIGESTe, and DIGESTt.
Results The median age of the patients were 13 months (7–39 months), and male-to-female ratio was 25:14. Sixty-seven percent of patients were type-C EA and 61% of them has associated anomalies; 38% of patients had aspiration (PAS = 6–8) in liquids and 10% in pudding consistency. Life-threatening/profound swallowing dysfunction in DIGESTe (DIGEST = 4) was seen in 13% (n = 5) of patients; 40% of EA patients showed severe problems in DIGESTt.
Conclusion DIGEST is a valid and reliable tool to define the efficacy and safety of swallowing in children with EA.

Published: September 2023

AbstractBone microarchitecture has several clinical implications over and above estimating bone strength. Computed tomography (CT) analysis mainly uses high-resolution peripheral quantitative CT and micro-CT, research imaging techniques, most often limited to peripheral skeleton assessment. Ultra-high-resolution (UHR) CT and photon-counting detector CT, two commercially available techniques, provide images that can approach the spatial resolution of the trabeculae, bringing bone microarchitecture analysis into clinical practice and improving depiction of bone vascularization, tumor matrix, and cortical and periosteal bone. This review presents bone microarchitecture anatomy, principles of analysis, reference measurements, and an update on the performance and potential clinical applications of these new CT techniques. We also share our clinical experience and technical considerations using an UHR-CT device.
Bone in Anorexia
Authors: Miquel Anne , Bousson Valérie 
Published: September 2023

AbstractAnorexia nervosa is a feeding disorder involving intentional weight loss. Restricted dietary intake leads to disturbed bone metabolism due to various factors, notably endocrine, that affect bone microarchitecture and incur risk of fracture. Mild to moderate anorexia shows a paradoxical increase in bone marrow adipose tissue, whereas severe forms show gelatinous transformation known as serous atrophy of bone marrow (SABM). Imaging assessment of the mineralized and adipose components uses several techniques: dual-energy X-ray absorptiometry, computed tomography, chemical shift magnetic resonance imaging (MRI), and single-voxel MR spectroscopy. SABM induces MRI bone signal disturbances that can be hard to interpret and may hinder visualization of the fracture line.

Published: September 2023

AbstractWe discuss several variants of the metaphyseal and diaphyseal bone surfaces that may be misleading in clinical practice. They include metaphyseal stripes, spiculated metaphyseal cortex, cortical desmoid, laminated lateral supracondylar ridge, cortical vascular canals, variations in shape or lucency of normal tuberosities, cortical thickening of normal ridges, and well-organized undulated hyperostosis at the proximal phalanges.

Published: September 2023

AbstractThe periosteum is a membrane that covers almost all bones in the body. It is a living structure but attracts little attention unless it reacts excessively. We highlight the important points in the anatomy, histology, and physiology of the periosteum, the stimuli and various aspects of periosteal reaction, and the main conditions underlying periosteal reaction.

Published: September 2023

AbstractAlthough the prevalence of Paget's disease has decreased over the past 20 years, incidental discovery on imaging is not unusual. The challenge is to establish the diagnosis, especially in unusual forms that may be mistaken for metastases. This review describes the typical imaging features of Paget's disease and some rare presentations that may be more difficult to recognize.

Published: September 2023

AbstractConsidering the importance of defining the minimum number of axons between recipient and donor branches, that is, the definition of histological compatibility in distal neurotizations for the success of the procedure and the surgeon's freedom to choose individualized strategies for each patient, this systematic review was conducted to find out the most recent studies on the subject. The objective of this systematic review was to determine the importance of the number of axons and the relationship between axon counts in the donor and recipient nerves in the success of nerve transfer. A literature review was performed on five international databases: Web of Science, Scopus, Wiley (Cochrane Database), Embase, and PubMed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed (2020 version), a guide designed to guide the elaboration of systematic literature reviews. One hundred and fifty-seven studies were found, and 23 were selected based on the eligibility criteria. The articles presented were conclusive in determining the importance of the number of axons in the success of nerve transfer. Still, the relationship between the number of axons in the donor and recipient nerves seems more relevant in the success of transfers and is not always explored by the authors. The review of the articles has provided compelling evidence that the number of axons is a critical determinant of the success of nerve transfer procedures. However, the relationship between the number of axons in the donor nerve and that in the recipient nerve appears to be even more crucial for successful transfers, a factor that is not always adequately explored by authors in the existing literature.

Published: September 2023

Preterm birth is a major cause of neonatal morbidity and mortality, but its etiology and risk factors are poorly understood. We undertook a scoping review to illustrate the breadth of risk factors for preterm birth that have been reported in the literature. We conducted a search in the PubMed database for articles published in the previous 5 years. We determined eligibility for this scoping review by screening titles and abstracts, followed by full-text review. We extracted odds ratios and other measures of association for each identified risk factor in the articles. A total of 2,509 unique articles were identified from the search, of which 314 were eligible for inclusion in our final analyses. We summarized risk factors and their relative impacts in the following categories: Activity, Psychological, Medical History, Toxicology, Genetics, and Vaginal Microbiome. Many risk factors for preterm birth have been reported. It is challenging to synthesize findings given the multitude of isolated risk factors that have been studied, inconsistent definitions of risk factors and outcomes, and use of different covariates in analyses. Novel methods of analyzing large datasets may promote a more comprehensive understanding of the etiology of preterm birth and ability to predict the outcome.

Published: September 2023

Abstract
Objective This article characterizes perspectives of ophthalmologists involved in the residency selection process regarding the potential impact of preference signaling on the ophthalmology residency match.
Methods An anonymous online questionnaire generated from SurveyMonkey was approved by the Association of University Professors of Ophthalmology (AUPO) Data Resource Committee for distribution to 391 individuals from the AUPO Departmental Chairs, Program Directors, and Directors of Medical Student Education email listservs in August 2022.
Results A total of 96 (24.6%) ophthalmology faculty completed the questionnaire. The majority (n = 76, 79.2%) agreed or strongly agreed that preference signaling should be implemented in the ophthalmology residency application system. Most respondents agreed or strongly agreed that preference signaling will allow for more holistic reviews of applications (n = 55, 57.3%), agreed or strongly agreed that it will benefit applicants who do not have connections to home programs or faculty that can reach out to desired programs (n = 81, 84.4%), and agreed or strongly agreed that it will improve the distribution of interviews to applicants (n = 76, 79.2%). Participants agreed or strongly agreed that applicants who have signaled interest in their program will receive preference when offering interviews (n = 59, 61.5%), and those signals will be used as a tiebreaker for similar applications (n = 75, 78.1%). The majority of participants believed that the ideal number of preference signals' applicants should be given three to four signals (n = 35, 36.0%) or five to six signals (n = 29, 30.2%).
Conclusion A majority of ophthalmology faculty surveyed support the integration of preference signaling into the ophthalmology residency match.

Published: September 2023

AbstractIntimate partner violence (IPV) gained global notoriety as a preventable public health menace affecting 30% of women worldwide. The IPV which is implicated as a significant cause of premature mortality and morbidity worldwide, increased during the SARS-CoV-2 pandemic. The purpose of this study is to synthesize evidence regarding the impact of the SARS-CoV-2 pandemic on the incidence of IPV in Africa, occurring between 1st January, 2020 to 31st December, 2022. Using the Tricco et al. (2018) procedure, a thorough literature search was done in PubMed, Cochrane Library, ScienceDirect, Dimensions, Taylor and Francis, Chicago Journals, Emerald Insight, JSTOR, Google Scholar, and MedRxiv. Consistent with the inclusion and exclusion protocols, 10 peer-reviewed articles were eligible and used for this review. We report that : (i) the SARS-CoV-2 pandemic escalated the vulnerabilities of people to economic hardship, resulting in the increased incidence of IPV between 2020 and 2022 in Africa, (ii) psychological/emotional abuse was the most prevalent form of IPV suffered by victims, (iii) mental health conditions were the most reported effects of IPV on victims. The prevalence of IPV could undermine the achievement of the sustainable development goals (SDG)s 2.2, 4, 5.2, 11.7, and 16 by Africa, limiting the continent’s quest to achieve full eradication of all types of violence against women. This study appears to be the first to review the literature on how the SARS-CoV-2 pandemic influenced the incidence of IPV in Africa. We recommend that governments provide women with financial support using social support schemes, create sustainable livelihood opportunities for women, and intensify public sensitisation and education about IPV and available help-seeking opportunities. We recommend a study into the structures available for dealing with IPV in Africa.
