Abstract

Precise manipulation of catalyst structure at atomic level holds the key to regulating the catalyst performance. Herein, we show that single Cr atom doping in In2O3 can modulate the In-O bond with significantly improved performance in CO2 hydrogenation to methanol. A “distance effect” concept is proposed to interpret the function of Cr doping, wherein Cr stimulates the directly coordinated oxygen to form Cr and In confined oxygen vacancy (Ov) active sites for the enhancement of CO2 activation and lowering the energy barrier for the HCOO* to H2COO* transformation (the rate-determining step). In addition, Cr assists in maintaining the structure stability and inhibits the over-reduction of In2O3 through the tethering of nearby oxygen atoms. The Cr-In2O3 catalyst exhibits a CO2 conversion of 9.4% and CH3OH selectivity of 92.0% under the reaction conditions of 250°C, 5 MPa, and 3000 mL·gcat−1·h− 1, along with a remarkable stability over 500 h on-stream testing. This study demonstrates a new paradigm for the modulation of In-O bonds in In2O3-based catalysts to break the trade-off between the reactivity and stability of the CO2 hydrogenation reaction.
Health Perceptions and Practices of a Telewellness Fitness Program: Exploratory Case Study
Authors: Ahumada-Newhart Veronica , Wood Taffeta , Satake Noriko , Marcin James P 
Published: September 2024

Abstract

Background
During the COVID-19 pandemic, many people lacked access to group fitness opportunities due to elevated risk of infection, lockdown, and closure of exercise facilities. Additionally, many people experienced higher than average rates of mental health burden (eg, anxiety and stress). To help address these needs, an existing in-person community exercise class, taught by a faculty member from an academic medical center, transitioned to an online synchronous (OS) physical fitness class via the Zoom (Zoom Video Communications) videoconferencing platform. As such, the instructor advertised the OS fitness classes through an existing email list of community members and university faculty, staff, students, or alumni email listservs. This telewellness intervention sought to create a sense of community, build social support, and promote physical and mental wellness during the COVID-19 pandemic.

Objective
Our aim was to determine the perceived mental and physical health benefits of attending an OS fitness class for community members, including health care workers. We also assessed the use and functionality of related technologies necessary for delivering and attending the fitness classes.

Methods
An online survey questionnaire was created and tested to collect quantitative and qualitative data for an exploratory study. Data were collected to evaluate the fitness class, motivation, perceived health benefits, and related technologies. A convenience sample of people who had participated in the OS fitness classes was recruited for this study via an emailed recruitment flyer.

Results
A total of 51 participants accessed and completed the survey questionnaire. Survey participants consisted of 28 of 51 (55%) with a university affiliation, 17 of 51 (33%) with no university affiliation, and 6 of 51 (12%) who declined to state. The largest group of participants reporting full-time employment (18/51, 35%) also reported university affiliation with the academic medical center. In this group, 13 of 51 (25%) participants reported full-time employment, university affiliation, and doctoral degrees. High overall exercise class satisfaction was observed in the survey responses (mean 4.0, SD 1). Data analyses revealed significant perceived value of both mental and physical health benefits as motivating factors for participating in the OS fitness class. Challenges were identified as not being able to receive individual feedback from the instructor and the inability of some participants to see if they were in sync with the rest of the class.

Conclusions
Results provide preliminary support for the use of online videoconferencing fitness platforms to promote wellness and facilitate group exercise in the community during times of high infection risk. Future studies should continue to explore perceived benefits, mental and physical wellness, best practices, and the design of related technologies.

Published: September 2024

Abstract

Background
Chemsex prevalence is still not well known, and both the lack of homogeneity and cultural component of chemsex practices are usually overlooked.

Objective
This study aims to estimate the proportion of sexual minority men (SMM) engaging in chemsex sessions, while understanding the cultural dimension of chemsex, and to analyze distinct session typologies with potential risk differences and the sociodemographic factors associated with engaging in them.

Methods
A total of 5711 SMM residing throughout Spain participated in an anonymous web-based survey that assessed chemsex session engagement and characteristics, drug use, and sociodemographic variables. We measured the association of sociodemographic factors with engaging in chemsex sessions by calculating adjusted prevalence ratios, using multivariate Poisson regression analysis. Chemsex typologies were analyzed using latent class analysis, and sociodemographic factors were associated with the different risk classes.

Results
Our results determined that 21.1% (1205/5711; 95% CI 20.0%‐22.1%) of SMM engaged in chemsex sessions during their lifetime. Participating in sessions was significantly associated with being a migrant, not having a comfortable financial situation, openly living their sexuality, residing in bigger municipalities, older age, using steroids, and living with HIV (adjusted prevalence ratio: range 1.17-2.01; all P values <.05). Three typologies of sessions with different risks were identified with latent class analysis, with 23.2% of SMM engaging in sessions taking part in higher-risk ones, which was associated with younger age, using steroids, living in bigger municipalities, openly living their sexuality, and living with HIV, compared to SMM engaging in lower-risk sessions (odds ratio: range 2.75-4.99).

Conclusions
Chemsex is relatively common among SMM in Spain, but it is important to differentiate typologies of sessions with varying risks, and the proportion of SMM engaging in high-risk sessions is low. Chemsex is highly associated with sociodemographic factors. Chemsex should be prioritized in public health programs, which should consider the different forms of sessions with their varying risks and prevalence, while also considering the cultural dimension inherent to chemsex.

Abstract

Background
This study aimed to evaluate the safety and efficacy of emergency and prophylactic uterine artery embolization (UAE) in our clinical practice, including technical success, clinical success, and associated complications.

Patients and methods
In this retrospective study, we analyzed 64 women who underwent emergency (n =18) and prophylactic (n = 46) UAE. Indications for emergency UAE included postpartum hemorrhage or severe hemorrhage during pregnancy termination, while prophylactic UAE was performed prior to surgical removal of retained products of conception (RPOC), delivery with abnormal placental implantation, or pregnancy termination (cervical pregnancy or fetal anomalies accompanied by abnormal placental implantation). Technical success of UAE was defined as complete exclusion of the vascular lesion and contrast stasis on the final angiogram, while clinical success was defined as cessation of bleeding after UAE Termination without a hysterectomy.

Results
The overall clinical success of UAE in our study was 97% (62/64). All embolization procedures were technically and clinically successful in the prophylactic group without life-threatening hemorrhages or hysterectomies (100% success rate, 46/46). However, while 100% technical success was similarly attained in the emergency group, bleeding was successfully controlled in 89% of cases (16/18). In two patients with significant blood loss (over 2000 mL), embolization failed to achieve hemostasis, resulting in persistent bleeding and subsequent hysterectomy.

Conclusions
UAE is a safe and effective procedure for managing primary postpartum hemorrhage or severe hemorrhage during pregnancy termination and for decreasing the risk of severe hemorrhage during surgical removal of RPOC, delivery with abnormal placental implantation, or pregnancy
Laser speckle contrast imaging of perfusion in oncological clinical applications: a literature review
Authors: Hren Rok , Brezar Simona Kranjc , Marhl Urban , Sersa Gregor 
Published: September 2024

Abstract

Background
Laser speckle coherence imaging (LSCI) is an emerging imaging modality that enables noninvasive visualization and assessment of tissue perfusion and microcirculation. In this article, we evaluated LSCI in imaging perfusion in clinical oncology through a systematic review of the literature.

Methods
The inclusion criterion for the literature search in PubMed, Web of Science and Scopus electronic databases was the use of LSCI in clinical oncology, meaning that all animal, phantom, ex vivo, experimental, research and development, and purely methodological studies were excluded.

Results
Thirty-six articles met the inclusion criteria. The anatomic locations of the neoplasms in the selected articles were brain (5 articles), breasts (2 articles), endocrine glands (4 articles), skin (12 articles), and the gastrointestinal tract (13 articles).

Conclusions
While LSCI is emerging as an appealing imaging modality, it is crucial for more clinical sites to initiate clinical trials. A lack of standardized protocols and interpretation guidelines are posing the most significant challenge.

Published: September 2024

Abstract

Background
To evaluate the role of the novel quantitative imaging biomarker (QIB) SUVX% of 18F-FDG uptake extracted from early 18F-FDG-PET/CT scan at 4 weeks for the detection of immune-related adverse events (rAE) in a cohort of patients with metastatic melanoma (mM) patients receiving immune-checkpoint inhibitors (ICI).

Patients and methods
In this prospective non-interventional, one-centre clinical study, patients with mM, receiving ICI treatment, were regularly followed by 18F-FDG PET/CT. Patients were scanned at baseline, early point at week four (W4), week sixteen (W16) and week thirty-two (W32) after ICI initiation. A convolutional neural network (CNN) was used to segment three organs: lung, bowel, thyroid. QIB of irAE - SUVX% - was analyzed within the target organs and correlated with the clinical irAE status. Area under the receiver-operating characteristic curve (AUROC) was used to quantify irAE detection performance.

Results
A total of 242 18F-FDG PET/CT images of 71 mM patients were prospectively collected and analysed. The early W4 scan showed improved detection only for the thyroid gland compared to W32 scan (p=0.047). The AUROC for detection of irAE in the three target organs was highest when SUVX% was extracted from W16 scan and was 0.76 for lung, 0.53 for bowel and 0.81 for thyroid. SUVX% extracted from W4 scan did not improve detection of irAE compared to W16 scan (lung: p = 0.54, bowel: p = 0.75, thyroid: p = 0.3, DeLong test), as well as compared to W32 scan in lungs (p = 0.32) and bowel (p = 0.3).

Conclusions
Early time point 18F-FDG PET/CT at W4 did not lead to statistically significant earlier detection of irAE. However, organ 18F-FDG uptake as quantified by SUVX% proved to be a consistent QIB of irAE. To better assess the role of 18F-FDG PET/CT in irAE detection, the time evolution of 18F-FDG PET/CT quantifiable inflammation would be of essence, only achievable in multi centric studies.
Subdiaphragmatic activity-related artifacts in myocardial perfusion scintigraphy
Authors: Strok Anja , Salobir Barbara Guzic , Stalc Monika , Zaletel Katja 
Published: September 2024

Abstract

Background
Myocardial perfusion imaging (MPI) with single photon emission computed tomography is an established non-invasive technique for assessing myocardial ischemia. This method involves the intravenous administration of a radiopharmaceutical that accumulates in the heart muscle proportional to regional blood flow. However, image quality and diagnostic accuracy can be compromised by various technical and patient-related factors, including high non-specific radiopharmaceutical uptake in abdominal organs such as the stomach, intestines, liver, and gall-bladder, leading to subdiaphragmatic artifacts. These artifacts are particularly problematic for evaluating inferior wall perfusion and often necessitate repeated imaging, which decreases gamma camera availability and prolongs imaging times.

Conclusions
Despite numerous investigated techniques to reduce interfering gastrointestinal activity, results have been inconsistent, and current MPI guidelines provide scant information on effective procedures to mitigate this issue. Based on our experience, some possible approaches to reducing artifacts include choosing stress testing with an exercise stress test, when possible, late imaging, fluid intake, and consuming carbonated water immediately before imaging.

OBJECTIVES: The primary objective was to compare sensory processing measures in people attending specialist orthopaedic consultation for management of persistent shoulder pain with control participants. The secondary objective was to compare the groups’ sociodemographic, clinical, general health and lifestyle, and psychological characteristics. DESIGN: Observational cross-sectional. METHODS: Participants with shoulder pain for ≥3 months, who attended a public hospital orthopaedic department (n = 119), and community participants without shoulder pain (n = 44) underwent a standardized quantitative sensory testing protocol, measuring pressure pain threshold, temporal summation, and conditioned pain modulation. Sociodemographic, clinical, general health and lifestyle, and psychological characteristics were also collected. RESULTS: Participants with shoulder pain had significantly lower pressure pain thresholds at all sites (ie, local and widespread mechanical hyperalgesia) and significantly decreased conditioned pain modulation effect (ie, descending inhibition of nociception) than control participants. There was no significant difference between groups for temporal summation. Participants with shoulder pain had decreased general health and function, less healthy lifestyles, and poorer psychological health compared with controls. CONCLUSION: People referred to specialist orthopaedic care for management of persistent shoulder pain had clinical signs of altered sensory processing and poor health outcomes.

Книга во многом является новаторской, потому что тема церковного суда остается мало разработанной в отечественной историографии. Это связано с совершенно разными факторами: с отсутствием и неполнотой источниковой базы для раннего периода, с краткостью бесцензурного периода в истории РПЦ, позволяющего изучать историю синодального времени, с отсутствием доступа исследователей к церковным архивам советского периода, с длительным отсутствием интереса к данной тематике в советской историографии.
The book is innovative in many ways, because the topic of church courts remains poorly developed in Russian historiography. This is due to completely different factors: the absence and incompleteness of the source base for the early period, the brevity of the uncensored period in the history of the Russian Orthodox Church, which allows one to study the history of the synodal period, the lack of access for researchers to church archives of the Soviet period, and the long-term lack of interest in this topic in Soviet historiography.
