ABSTRACT Purpose Abnormal restrictions at myofascial interfaces are a key factor in chronic low back pain (CLBP) with myofascial pain syndrome (MPS), but no established imaging method exists for quantitative assessment. This pilot study evaluated the clinical feasibility of MR elastography (MRE)‐based slip interface imaging (SII) for visualizing myofascial mobility in CLBP‐MPS patients versus age−/sex‐/BMI‐matched healthy participants. A new SII biomarker, maximal normalized displacement discontinuity (), was introduced, and the previously developed normalized octahedral shear strain (NOSS) map was used for comparison. Preliminary assessments of vibration‐frequency effects, repeatability, and group differences in inter‐muscular mobility were conducted. Methods MRE was conducted at 30, 60, and 90 Hz to compare with NOSS for visualizing inter‐muscular slip interfaces at the quadratus lumborum‐erector spinae (QL‐ES) and erector spinae‐multifidus (ES‐M) muscle boundaries at L3‐L4. Repeatability of and NOSS was assessed at 30 Hz (identified as the best‐performing frequency) using within‐subject coefficients of variation and a linear mixed‐effects model from within‐ and between‐day scans. Clinical feasibility was then assessed via Wilcoxon rank‐sum tests in six CLBP‐MPS patients and matched controls. Results at 30 Hz exhibited superior delineation of slip interfaces compared to higher frequencies and NOSS. demonstrated significantly lower variation and better repeatability than NOSS. Healthy participants showed continuous, well‐defined slip interfaces, whereas CLBP‐MPS patients displayed disrupted interfaces with significant mobility reduction at L4 ES‐M. Conclusion SII with lower vibration frequency and map enhances visualization of lower back myofascial mobility and shows potential for assessing differences between healthy individuals and CLBP‐MPS patients.

Background: There is a lack of data regarding the current state of lactation accommodations at continuing medical education (CME) events to guide best practice recommendations. Objective: To evaluate CME attendee attitudes, experiences, and preferences as it pertains to lactation support accommodations at CME events. Design: A cross-sectional study utilizing an electronic-based survey. Methods: Surveys were administered electronically to attendees of seven CME courses from August 2022 to October 2023, and de-identified data were collected to a secure database. Attitudes regarding lactation accommodations, personal preferences for lactation accommodations, and experiences with lactation at CME events were analyzed. Results: Of the 337 survey respondents, 169 had personal experience with lactation and 47 had experience with lactation at a CME course within the past 10 years. The majority of respondents agreed that lactation accommodations should be a priority ( n = 264, 83%) and are a medical need ( n = 285, 89%). Of those with recent experience lactating at a CME course, only 19% ( n = 9) indicated adequate lactation accommodations were provided. Due to inadequate accommodations, 77% ( n = 36) of respondents experienced decreased participation in the CME course content, 70% ( n = 33) claimed fewer hours of CME credit, and 74% ( n = 35) experienced decreased satisfaction in the CME course. Preferences for lactation accommodations included proximity to the meeting, audio–visual streaming of content, privacy, security, and signage supporting lactation in addition to an adequate designated space with access to an electrical plug and water supply. Conclusions: The current state of lactation accommodations at CME courses is inadequate and contributes to inequitable experiences for lactating participants. Course participants are supportive of lactating healthcare professionals at CME courses and recognize lactation accommodations as a priority. Further work is needed to inform and institute changes to lactation accommodations for healthcare professionals.

Abstract Introduction: Cystic fibrosis (CF) is a genetic disorder characterized by defective chloride ion transport, leading to thick mucus production, chronic respiratory infections, and other multisystem involvement. Although CF is often diagnosed in childhood, the condition can be missed or misdiagnosed in adults. Description of Case: We present the case of a 60-year-old male from India who was diagnosed with CF after a prolonged period of sinopulmonary symptoms. He initially presented in 2014. His medical history was pertinent for asthma, and multiple episodes of clinically and radiographically confirmed pneumonia and polypoid sinusitis requiring IV antibiotics and sinus surgery. He carried a prior diagnosis of allergic bronchopulmonary aspergillosis treated with itraconazole and steroids, as well as elevated IgE levels. His CT chest was notable for extensive bronchiectasis, bronchial wall thickening, and mucus plugging of both lungs. He had no known family history of CF. Sweat chloride testing was in the intermediate range (44, 47 mmol/L; normal <30 mmol/L, intermediate 30 to 59 mmol/L, abnormal >59 mmol/L). Given high suspicion for CF, cystic fibrosis transmembrane conductance regulator (CFTR) full gene analysis was pursued. Sequence analysis and multiplex ligation-dependent probe amplification of the CFTR gene detected heterozygous sequence changes c.1717-2A>T, classified as likely deleterious, and c.1367T>C (p.V456A), variant of uncertain significance. He was thus initially diagnosed as a CF carrier. He re-presented in 2024 with decline in pulmonary function testing and continued sinopulmonary infections. Genetic testing results from 2014 were re-analyzed. Between initial presentation and present, his V456A variant was upgraded to pathogenic. He met diagnostic criteria for CF with two pathogenic CFTR variants, a repeated intermediate sweat chloride (47 mmol/L) suggestive of CFTR protein dysfunction, and disease that could be attributed to CFTR dysfunction. He subsequently started TRIKAFTA® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) and airway clearance therapy. Discussion: The diagnosis of CF in adults can be challenging, particularly in individuals without a known family history, intermediate sweat chloride testing, and with inconclusive genetic testing. Our understanding of CF in Asian populations is limited. CF is suspected to be underreported in patients with Southeast Asian ancestry in part due to genetic heterogeneity. The interpretation of certain genetic variants can evolve over time. A variant of unknown significance may later be reclassified as pathogenic, revealing its true role in disease development. This highlights the critical importance of regularly re-evaluating genetic test results.

Objective: Multicancer Detection (MCD) tests, such as the GRAIL Galleri, offer a novel approach to cancer screening by detecting cancer-specific methylation patterns in cell-free DNA through a single blood sample. This study evaluated an 18-month implementation of MCD testing in a tertiary ambulatory internal medicine clinic. Patients and Methods: Between June 2022 and November 2023, 2244 asymptomatic (without symptoms attributed to cancer) patients underwent MCD testing. The study focused on operational workflows, patient and physician education, and diagnostic follow-up of positive results. Standardized materials, including electronic health record (EHR) workflows, FAQs, and diagnostic pathways, were developed to facilitate implementation. Challenges included managing false positives, patient anxiety, costs, and ethical considerations. Results: Of the 2244 patients tested, 17 (0.76%) had positive results, and 15 underwent further diagnostic evaluation. Cancer was confirmed in 11 (73.3%) patients, including cases of breast, colon, esophageal, lymphoma, ovarian, and pancreatic cancers. Four patients had no identifiable malignancy despite comprehensive work-up. Conclusions: MCD testing is feasible in routine clinical workflows, with 73% of positive cases yielding cancer diagnoses. While promising, further research is required to assess long-term outcomes, cost-effectiveness, and optimal implementation strategies of cancer interception in broader healthcare settings.

Objectives: To identify patient characteristics, health concerns, and barriers to care based on overweight or obesity. Methods: A 50-question anonymous survey was administered to patients. Data were compared by body mass index (BMI). Results: Among 3976 distributed surveys, 899 were returned and 682 were analyzed. Most respondents were women (60%), White (94%), and married/partnered (65%) and had some college education (80%). Younger and unmarried persons had higher BMI ( P < .001). Concern for quality of life ( P < .001) and importance of lifestyle changes ( P = .006) increased with BMI, but confidence in making changes decreased as BMI increased ( P < .001). Perceived good health decreased with increasing BMI ( P < .001), whereas depression and other comorbid conditions increased. Self-esteem decreased and stigma increased with higher BMI (both P < .001). Weight discussions with clinicians ( P < .001) and belief that clinicians should be involved in weight management ( P = .002) increased with BMI, yet self-perception of being judged by clinicians also increased ( P < .001). As BMI increased, delays in seeking health care increased ( P < .001). Conclusions: This survey study highlights perceived health concerns and barriers to care among persons with overweight and obesity. With higher BMI, self-esteem decreased, and stigma, self-perception of poor health, perception of being judged by clinicians, and delay in seeking medical care increased.

Background and Objectives: Proteomics encompasses the exploration of protein composition, regulation, function, and pathways. Its influence spans diverse clinical fields and holds promise in addressing various women’s health conditions, including cancers, osteoporosis, and cardiovascular disorders. However, no comprehensive summary of proteomics and menopausal health exists. Our objective was to summarize proteomic profiles associated with diseases and disorders in peri- and postmenopausal women. Materials and Methods: We conducted a comprehensive search of databases including PubMed, Google Scholar, the Cochrane database, Elsevier, and ScienceDirect until 2022. A total of 253 studies were identified, and 41 studies met the inclusion criteria to identify data of interest. These included the study design, disease, and proteomics/proteins of significance, as described by the authors. Results: The 41 studies covered diverse areas, including bone disorders (10 studies), cardiovascular diseases (5 studies), oncological malignancies (10 studies), and various conditions, such as obesity, nonalcoholic liver disease, the effects of hormone replacement therapy, and neurological diseases (16 studies). The results of our study indicate that proteomic profiles correlate with heart disease in peri- and postmenopausal women, with distinct sex differences. Furthermore, proteomic profiles significantly differ between women with and without osteoporosis. Additionally, patients with breast, ovarian, and endometrial cancer exhibit notable variations in proteomic profiles compared to those without these conditions. Conclusions: Proteomics has the potential to enhance risk assessment and disease monitoring in peri- and postmenopausal women. By analyzing unique protein profiles, clinicians can identify individuals with heightened susceptibility to specific diseases or those already affected by established conditions. This review suggests that there is sufficient preliminary data related to proteomics in peri- and postmenopausal women for early identification of cardiovascular disease, osteoporosis, and cancers, disease monitoring, and tailoring individualized therapies. Rigorous validation studies involving large populations are essential before drawing definitive conclusions regarding the clinical applicability of proteomic findings.

Background Before the COVID-19 pandemic began, medical staff and academic department workers reported increasing levels of stress and burnout because of strain on the health care system. The COVID-19 pandemic exacerbated this strain and introduced several novel stressors, which included transitioning to remote work. Safe and scalable strategies are needed to help health care workers cope with these stressors. Aromatherapy may help address this need. Objectives To assess the effect of 2 aromatherapy interventions (essential oil blends termed STILL and FOCUS) on perceived mental/psychological health parameters for academic department workers working from home during the COVID-19 pandemic. Methods Participants were advised to use STILL for 5 days (Monday through Friday). After a 2-day washout period (Saturday and Sunday), participants were instructed to use FOCUS for 5 days (Monday through Friday). Participants completed a visual analog scale survey evaluating restlessness, fatigue, anxiety, stress, happiness, energy, relaxation, calmness, and well-being before and after each of the 2 intervention periods. Results Twenty academic department remote workers participated in the study. Mental/psychological health surveys were completed by 6 participants before and after using STILL and by 10 before and after using FOCUS. Five participants answered all survey questions before and after both interventions. Although mean (SD) perceived stress scores improved after both the STILL (4.3 [2.3] vs 1.8 [1.7], P = .03) and FOCUS (2.9 [2.3] vs 1.5 [1.4], P = .02) interventions, this improvement was not statistically significant after Bonferroni correction (adjusted α = .006). Most participants (73.3%) reported that participating in the study was worthwhile, and 81.3% indicated that they would recommend aromatherapy to others. Conclusions The STILL and FOCUS aromatherapy interventions did not significantly improve mental/psychological health parameters for remote academic department workers, although perceived stress was marginally improved and participants reported a perceived benefit from using aromatherapy.

Objective: The purpose of this feasibility pilot study was to evaluate safety and adherence of a wearable brain sensing wellness device designed to reduce stress among healthcare professionals (HCP). Methods: A total of 40 HCP were invited to participate in an open-label pilot study. Participants were asked to use a brain sensing wearable device (MUSE-S™) on a daily basis to reduce their stress, for a total of 90 days. Total study participation duration was 180 days. Study enrollment began in August 2021 and ended December 2021. The exploratory outcomes included stress, depression, sleep, burn-out, resilience, quality of life, and cognition. Results: Among the 40 HCP in study, the majority were female (85%), white (87.5%) and with an average age of 41.3 ± 11.0 years (SD). Participants used the wearable device an average of 23.8 times over a 30-day period with a mean duration of 5.8 min with each use. Study results demonstrate the positive impact of guided mindfulness using the wearable device MUSE-S™ and its accompanying application (APP). A statistically significant improvement was found for a reduction in stress ( P < .001) and improvement in resilience ( P = .02), quality of life ( P = .003), and cognition ( P < .001). The majority (91.9%) of the participants indicated they felt more relaxed after using the device, and 73% indicated they would continue to use this device at end-of-study. No adverse effects were reported. Conclusion: Study results show that 3 to 10 min of guided meditation during work hours through the use of a brain sensing wearable device is safe and acceptable, with associated health benefits for HCP.

Abstract BACKGROUND Uncertainty remains over the relationship between blood pressure (BP) variability (BPV), measured in hospital settings, and clinical outcomes following acute ischemic stroke (AIS). We examined the association between within-person systolic blood pressure (SBP) variability (SBPV) during hospitalization and readmission-free survival, all-cause readmission, or all-cause mortality 1 year after AIS. METHODS In a cohort of 862 consecutive patients (age [mean ± SD] 75 ± 15 years, 55% women) with AIS (2005–2018, follow-up through 2019), we measured SBPV as quartiles of standard deviations (SD) and coefficient of variation (CV) from a median of 16 SBP readings obtained throughout hospitalization. RESULTS In the cumulative cohort, the measured SD and CV of SBP in mmHg were 16 ± 6 and 10 ± 5, respectively. The hazard ratios (HR) for readmission-free survival between the highest vs. lowest quartiles were 1.44 (95% confidence interval [CI] 1.04–1.81) for SD and 1.29 (95% CI 0.94–1.78) for CV after adjustment for demographics and comorbidities. Similarly, incident readmission or mortality remained consistent between the highest vs. lowest quartiles of SD and CV (readmission: HR 1.29 [95% CI 0.90–1.78] for SD, HR 1.29 [95% CI 0.94–1.78] for CV; mortality: HR 1.15 [95% CI 0.71–1.87] for SD, HR 0.86 [95% CI 0.55–1.36] for CV). CONCULSIONS In patients with first AIS, SBPV measured as quartiles of SD or CV based on multiple readings throughout hospitalization has no independent prognostic implications for the readmission-free survival, readmission, or mortality. This underscores the importance of overall patient care rather than a specific focus on BP parameters during hospitalization for AIS.

Pain is the most frequently encountered symptom by patients with fibromyalgia (FM). Dietary supplements (DSs) in particular have a proven impact as a possible adjunctive therapy for symptom management in FM. However, there is currently no conclusive review outlining the evidence for DSs in pain management in FM. This study aims to assess currently available studies evaluating the use of DSs for pain relief in FM. Randomized controlled trials regarding the use of DSs on adult FM patients were included for evidence synthesis. Study results indicated that DSs significantly relieved pain in FM (SMD 1.23; 95% CI 0.02–2.43, P = 0.046) but did not improve quality of life (QoL) (SMD 0.73; 95% CI −0.07–1.53, P = 0.075) in the data. Adverse events of DSs varied from mild to severe, with the most common being gastrointestinal symptoms and androgenic side effects in 5.7% and 3.9% of patients, respectively. More well-designed RCTs are required in the future. The protocol for this review has been published on PROSPERO (CRD42020149941).
