Psychological Connection to the Gay Community and Negative Self-Appraisals in Middle-Aged and Older Men Who Have Sex with Men: The Mediating Effects of Fitness Engagement.

J Gerontol B Psychol Sci Soc Sci 2021 May 4. Epub 2021 May 4.

Department of Medicine, Division of General Internal Medicine, Georgetown University.

Objectives: Connections to the gay community may elicit negative self-appraisals among men who have sex with men (MSM), which may be exacerbated for people with HIV (PWH). Fitness engagement may mediate self-appraisals by maintaining or improving appearance and health. We hypothesized that gay community connections would be positively related to negative self-appraisal and explored whether this association would be mediated by fitness engagement and moderated by HIV status.

A multi-state occupancy model to non-invasively monitor visible signs of wildlife health with camera traps that accounts for image quality.

J Anim Ecol 2021 May 3. Epub 2021 May 3.

Department of Conservation and Science, Lincoln Park Zoo, Chicago, Illinois, 60614, USA.

Camera traps are an increasingly popular tool to monitor wildlife distributions. However, traditional analytical approaches to camera trap data are difficult to apply to visible wildlife characteristics in single images, such as infection status. Several parasites produce visible signs of infection that could be sampled via camera traps. Read More

iRFP (near-infrared fluorescent protein) imaging of subcutaneous and deep tissue tumours in mice highlights differences between imaging platforms.

Cancer Cell Int 2021 May 3;21(1):247. Epub 2021 May 3.

Tumour Suppressors Group, CRUK Manchester Institute, University of Manchester, Alderley Park, Manchester, SK10 4TG, UK.

Background: In vivo imaging using fluorescence is used in cancer biology for the detection, measurement and monitoring of tumours. This can be achieved with the expression of fluorescent proteins such as iRFP, which emits light at a wavelength less attenuated in biological tissues compared to light emitted by other fluorescent proteins such as GFP or RFP. Imaging platforms capable of detecting fluorescent tumours in small animals have been developed but studies comparing the performance of these platforms are scarce. Read More

Study protocol of the LARK (TROG 17.03) clinical trial: a phase II trial investigating the dosimetric impact of Liver Ablative Radiotherapy using Kilovoltage intrafraction monitoring.

BMC Cancer 2021 May 3;21(1):494. Epub 2021 May 3.

ACRF Image X Institute, Sydney, NSW, Australia.

Background: Stereotactic Ablative Body Radiotherapy (SABR) is a non-invasive treatment which allows delivery of an ablative radiation dose with high accuracy and precision. SABR is an established treatment for both primary and secondary liver malignancies, and technological advances have improved its efficacy and safety. Respiratory motion management to reduce tumour motion and image guidance to achieve targeting accuracy are crucial elements of liver SABR. Read More

Self-compassion and dissonance-based interventions for body image distress in young adult women.

Body Image 2021 Apr 30;38:191-200. Epub 2021 Apr 30.

Emory University, Department of Psychology, 36 Eagle Row, Atlanta, GA, 30322, USA. Electronic address:

Self-compassion interventions have been suggested as a potentially more acceptable way to address body image distress compared to interventions that emphasize challenging (often firmly entrenched) thin-ideals. In the current randomized controlled trial, young adult women endorsing body image concerns were randomized to a self-compassion (SC) intervention consisting of one in-person session plus one week of self-guided practice (n = 50), a similarly-structured dissonance-based (DB) intervention (n = 50), or a waitlist (WL) control (n = 51). Both brief interventions were acceptable and were more effective than WL. Read More

The Extrastriate Body Area and identity processing: An fMRI guided TMS study.

Physiol Rep 2021 Apr;9(8):e14711

Aix Marseille Univ, CNRS, ISM, Marseille, France.

The extrastriate body area (EBA) is a body-selective focal region located in the lateral occipito-temporal cortex that responds strongly to images of human bodies and body parts in comparison with other classes of stimuli. Whether EBA contributes also to the body recognition of self versus others remains in debate. We investigated whether EBA contributes to self-other distinction and whether there might be a hemispheric-side specificity to that contribution using double-pulse transcranial magnetic stimulation (TMS) in right-handed participants.

In recent years, there has been enormous interest in applying artificial intelligence (AI) to radiology. Although some of this interest may have been driven by exaggerated expectations that the technology can outperform radiologists in some tasks, there is a growing body of evidence that illustrates its limitations in medical imaging. The true potential of the technique probably lies somewhere in the middle, and AI will ultimately play a key role in medical imaging in the future. Read More

Zooming into cosmetic procedures during the COVID-19 pandemic: The provider's perspective.

Int J Womens Dermatol 2021 Mar 12;7(2):213-216. Epub 2021 Jan 12.

Massachusetts General Hospital, Department of Dermatology, Boston, MA, United States.

The COVID-19 pandemic has seen a massive shift toward virtual living, with video-conferencing now a primary means of communication for both work and social events. Individuals are finding themselves staring at their own video reflection, often for hours a day, scrutinizing a distorted image on screen and developing a negative self-perception. This survey study of over 100 board-certified dermatologists across the country elucidates a new problem of Zoom dysmorphia, where patients seek cosmetic procedures to improve their distorted appearance on video-conferencing calls.

The Use of Deep Learning and VR Technology in Film and Television Production From the Perspective of Audience Psychology.

Front Psychol 2021 18;12:634993. Epub 2021 Mar 18.

College of Business, Gachon University, Seoul, South Korea.

As the development of artificial intelligence (AI) technology, the deep-learning (DL)-based Virtual Reality (VR) technology, and DL technology are applied in human-computer interaction (HCI), and their impacts on modern film and TV works production and audience psychology are analyzed. In film and TV production, audiences have a higher demand for the verisimilitude and immersion of the works, especially in film production. Based on this, a 2D image recognition system for human body motions and a 3D recognition system for human body motions based on the convolutional neural network (CNN) algorithm of DL are proposed, and an analysis framework is established.

Bidirectional Mapping of Brain MRI and PET With 3D Reversible GAN for the Diagnosis of Alzheimer's Disease.

Front Neurosci 2021 9;15:646013. Epub 2021 Apr 9.

Combining multi-modality data for brain disease diagnosis such as Alzheimer's disease (AD) commonly leads to improved performance than those using a single modality. However, it is still challenging to train a multi-modality model since it is difficult in clinical practice to obtain complete data that includes all modality data. Generally speaking, it is difficult to obtain both magnetic resonance images (MRI) and positron emission tomography (PET) images of a single patient. Read More

"Pretty hurts": Acceptance of hegemonic feminine beauty ideals and reduced sexual well-being among Black women.

Body Image 2021 Apr 29;38:181-190. Epub 2021 Apr 29.

Department of Psychology, Macalester College, 1600 Grand Avenue, Saint Paul, MN, 55105, USA. Electronic address:

Although women are expected to idealize and achieve hegemonic feminine beauty standards such as being slender and lighter skinned, few studies have examined how women's investment in achieving these restrictive feminine appearance ideals may influence their sexual attitudes and behaviors. Even less is known about Black women. We surveyed 640 Black college women to test hypotheses that endorsement of hegemonic beauty ideals would be positively associated with four dimensions of negative sexual affect (sexual guilt, shame, emotional distancing, and self-consciousness) and negatively associated with two dimensions of sexual agency (sexual assertiveness and satisfaction).

Invest Radiol 2021 Jun;56(6):401-408

From the Biomedical Image Analysis Group, Department of Computing, Imperial College London, London, UK.

Purpose: The aims of this study were to train and evaluate deep learning models for automated segmentation of abdominal organs in whole-body magnetic resonance (MR) images from the UK Biobank (UKBB) and German National Cohort (GNC) MR imaging studies and to make these models available to the scientific community for analysis of these data sets.
