Objectives Long-term symptoms following infection with acute respiratory syndrome coronavirus-2 (SARS-CoV-2), termed post-acute sequelae of SARS-CoV-2 infection (PASC) or Long COVID (LC), persist beyond 90 days and may impact at least 10% of patients with acute infection. The exact cause of LC remains unknown, but several theories include persistent viral particles, immune dysfunction, and autonomic nervous system (ANS) imbalance, particularly involving the vagus nerve. Given the role of the vagus nerve in inflammation regulation, vagal nerve stimulation (VNS) is being explored as a treatment option. The present study aimed to evaluate the feasibility, safety, and exploratory effects of a handheld external transcutaneous cervical non-invasive VNS (tcVNS) on the primary endpoint of Post-COVID Functional Status (PCFS) grade, alongside secondary outcomes such as LC-related fatigue and other symptoms. Methods Participants from our Post COVID Care Clinic were randomized into treatment (tcVNS treatments two minutes, three times a day) and control (no VNS) groups for a study period of 12 weeks. Participants completed validated questionnaires, PET-CT scans, and inflammatory cytokines at baseline and 12 weeks. Results All randomized patients (8 tcVNS, 10 control) completed the 12-week study. Participants randomized to tcVNS were observed to have improvements in PHQ-9, PROMIS-F, and COMPASS-31 when compared to controls, but these differences were not statistically significant. Cortisol and DHEA were also observed to increase less in the tcVNS group when compared to the control group, but these changes were also not statistically significant. Conclusions tcVNS was well tolerated and may be a promising therapeutic approach for LC, a chronic disease with no approved treatments and very low rates of complete recovery.

Purpose While the clinical utility for Point-of-Care Ultrasound (POCUS) is well-established through its use in clinical practice to enhance diagnostic accuracy, expedite care, and improve patient interactions/communication, its impact on patient experience in outpatient consultative settings remains largely underexplored. We sought to evaluate patients’ experience and satisfaction by incorporating POCUS use during outpatient consultations. Methods In this prospective, cross-sectional survey study conducted in a consultative outpatient internal medicine practice, a continuous sample of 100 patients undergoing POCUS during routine medical evaluations participated. We assessed patient perspectives using a survey that was adapted from validated instruments. The following items were evaluated using the anonymized survey: the extent of patient understanding, the integration of POCUS into the consultation, its impact on patient-doctor communication, perceived quality of care, and overall patient experience. Results Most respondents felt better informed about their health (88%), more thoroughly examined (94%), and reported improved confidence in their physician’s assessment (92%) after the POCUS exam. In addition, POCUS was perceived as a natural part of the consultation (95%) and minimally burdensome (93%). Overall, 96% of study respondents agreed that POCUS improved their quality of care, and 98% described their experience as positive or very positive. Open-ended comments emphasized the immediacy of results, enhanced communication, and cost-effectiveness of the POCUS experience. Conclusion Incorporating POCUS in this environment improved patients’ perceptions of their physician, clinic, and overall care. These findings support the broader adoption of POCUS in similar clinical settings and its potential impact on healthcare delivery and patient satisfaction.

Abstract Objective: Weight gain and vasomotor symptoms (VMS) are common complaints in midlife women going through the menopause transition. A selective serotonin 2C (5-HT2C) receptor agonist, lorcaserin, which was previously approved by the Food and Drug Administration for weight loss, has unreported observational evidence suggesting improvement in VMS with its use. The goal of this pilot study was to evaluate the efficacy of lorcaserin for weight loss and management of VMS in overweight midlife women. Methods: This was a 24-week open label pilot study of 20 overweight midlife women, aged 45-60 years, who were experiencing severe VMS. Participants received lorcaserin at the standard dose of 10 mg twice daily for 12 weeks, followed by 12 weeks of observation off the drug. The primary outcomes were changes in weight and subjectively reported VMS. Results: At the end of 12 weeks, mean change in weight was −2.4 kg (90% CI, −3.2 to −1.7, P < 0.001). However, the participants returned to the baseline weight at 24 weeks. Participants also reported significant subjective improvement in VMS, with a mean ± SD change in self-reported hot flash frequency from baseline to week 12 of −5.4 ± 3.9 (decrease of 1.4 standard deviations). There was a rapid increase in the frequency of VMS within 2 weeks of discontinuation of lorcaserin with a tendency to approach the baseline frequency of VMS. Conclusions: In addition to its weight loss-inducing effect, 5-HT2C receptor modulation may have an additional beneficial effect on VMS in midlife women. A treatment option that targets both weight and VMS in midlife women is attractive. Video Summary: http://links.lww.com/MENO/A622.
