Cross-Sectional Analysis of Attitudes Towards Bariatric Surgery Tourism of Patients Attending a Weight Management Program: A Qualitative Study

Introduction: The upward trend of seeking bariatric surgery tourism will only grow with the globalization of medical care. We aim to describe the experiences participants of a supervised weight loss program in relation to their pursuit of bariatric tourism. Methods: Semi-structured interviews with an unbiased questionnaire were conducted to obtain a profound understanding of the current Irish bariatric surgery recruitment program and bariatric patients’ perception of it. Results: Analysis of interview data yielded 5 themes. Each theme was elaborated further with selected quotes from the coding process. Participants were asked to suggest potential solutions to current bariatric surgery and tourism support concerns in Ireland. Authors’ recommendations based on a literature review and the analysis of the interview transcripts are also provided. Conclusion: Any patients with morbid obesity and many years of attempted weight loss should receive a bariatric procedure to alleviate not only weight-related metabolic co-morbidities, but also the associated psychiatric burden. The currently available eligibility criteria and the lack of resources render an ideal surgical intervention inaccessible to many. Efforts must be made to scrutinize the efficacy of the existing criteria and the availability of resources. Alternatively, a bariatric tourism scheme that allows uninterrupted patient care should be developed

Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM
