ABSTRACT This study assessed the level of agreement of perceived improvements among pediatric patients with chronic pain and their parents following an interdisciplinary pain management program. This is a retrospective chart review of a heterogeneous group of pediatric patients with chronic pain who completed an interdisciplinary pain management program (IPMP) and their parents ( N = 172 pairs). The IPMP took place in an outpatient pain management center affiliated with an academic rehabilitation hospital. The outcome measures included the Multidimensional Patient Impression of Change (MPIC) and the MPIC parent version were administered post‐treatment. The levels of agreement on the MPIC were analyzed between child and parent using the free‐marginal kappa statistic. The majority of both the parents and the children evaluated the patients to be much or very much improved in six of the eight domains assessed. The levels of agreement in the ratings were fair to moderate among the patient–parent dyads. Parents endorsed significantly higher levels of improved overall pain and mood than their child did, whereas the patients reported greater levels of improved ability to cope with pain than their parents did. Both the patients and their parents reported high levels of perceived improvement following the IPMP. However, there were some differences in their ratings of improvements in overall pain, mood, and ability to cope with pain. Given that some of the perceptions were discrepant, it is recommended that feedback be obtained from the patient and their parent.

Abstract Introduction Screening individuals with latent tuberculosis infection (LTBI) from regions with varying TB endemicity is critical for global TB control. Immune responses to TB differ due to variations in exposure, immune adaptations, and environmental factors. This study evaluated antigen-specific immune responses in untreated LTBI individuals from low- and high-TB-endemic settings. Methods Peripheral blood mononuclear cells from untreated LTBI individuals from low-endemic (USA) and high-TB-endemic settings (Mexico) were stimulated with PPD, MTB300, ESAT-6/CFP-10 (RD1) peptides, mycobacterial glycopeptidolipids (GPL), and controls. We compare flow cytometric immune responses of T-cell intracellular cytokines and activation markers using non-parametric statistical methods. Results We studied age-matched, untreated LTBI individuals who tested IGRA(+)/TST(+) from low-TB-endemic (n = 18) and 18 healthcare workers from a high-TB-endemic settings. IGRA results showed no statistical differences across groups. The frequency of CD3+CD8+IFN-γ+HLA-DR+ and total CD3+TNF-α+ T cells after RD1 stimulation was significantly higher in the high-TB-endemic group (P < 0.05). Additionally, we observed significant increased frequencies in CD3/CD4+TNF-α+HLA-DR+ and CD8+TNF-α+HLA-DR+ T cells stimulated by GPL in the same group, probably associated with nontuberculous mycobacteria (NTM) exposures. Our findings suggest possible recent TB and NTM exposures in healthcare workers from a high-TB-endemic setting, resulted in increased antigen-specific adaptive TNF-α and IFN-γ producing T cells, which are important for pathogen control and immunity. Conclusion We found significant differences in antigen-specific cell immunity, including HLA-DR activated T-cells, a marker of recent antigen encounter, in individuals from a high-TB-endemic settings. These findings underscore the importance of settings-specific immune biomarkers for improving LTBI diagnostics, clinical management, and vaccination trials.

Background: Itraconazole is the preferred antifungal agent for mild to moderate histoplasmosis and step-down therapy following amphotericin B treatment. Although hydroxy-itraconazole, a major metabolite of itraconazole, displays antifungal activity comparable with that of the parent compound, its role in therapeutic drug monitoring targets for histoplasmosis remains uncertain. Methods: The objective was to compare clinical outcomes and adverse events using itraconazole parent-compound concentrations alone versus combined itraconazole and hydroxy-itraconazole concentrations in patients treated for histoplasmosis. This retrospective cohort study included adults with probable or proven histoplasmosis who received itraconazole and had at least 1 documented serum concentration. The primary outcome was clinical response across 3 groups: (1) parent (itraconazole parent-compound concentration >1.0 mcg/mL), (2) combined (parent-compound concentration <1.0 mcg/mL with combined itraconazole plus hydroxy-itraconazole >1.0 mcg/mL), and (3) subtherapeutic (failure to reach either threshold). Treatment response and adverse events were analyzed using the Fisher exact test. Results: Among 108 patients (parent, n = 40; combined, n = 40; subtherapeutic, n = 28), response rates differed across groups (parent (95%); combined (90%); subtherapeutic (67.9%); P = 0.006). There was no difference between the parent and combined groups. Adverse events did not differ, although drug discontinuation occurred more frequently in the subtherapeutic group (parent (5%); combined (20%); subtherapeutic (25%); P = 0.04). Conclusions: Patients who failed to achieve either an itraconazole concentration >1 mcg/mL or a combined itraconazole plus hydroxy-itraconazole concentration >1 mcg/mL had lower response rates. Similar outcomes among patients achieving the itraconazole target alone and those achieving the combined target suggest that hydroxy-itraconazole concentrations may contribute to therapeutic drug monitoring targets in histoplasmosis.

Background: Rural communities face worsening surgical access because of hospital closures and workforce shortages. Although osteopathic physicians have historically practiced in rural settings, their contribution to the contemporary rural surgical workforce remains poorly defined. Study Design: Cross-sectional analysis of 74,404 US attending surgeons across seven specialties using the 2023 Centers for Medicare & Medicaid Services Doctors and Clinicians database. Practice addresses were linked to 2020 Rural-Urban Commuting Area codes, Area Deprivation Index quintiles, and census tract population density. Rural practice (mean Rural-Urban Commuting Area score ≥4) was modeled using multivariable logistic regression adjusted for specialty, graduation cohort, sex, Census division, and state urbanization, with state-clustered standard errors. Results: Rural practice was more common among DO than MD surgeons (18.3% vs 9.7%; risk difference, 8.6 percentage points; 95% CI, 7.6–9.6). Across all specialties, DO surgeons practiced in more socioeconomically deprived communities. After adjustment, DO surgeons had twice the odds of rural practice compared with MD surgeons (OR, 2.05; 95% CI, 1.85–2.28). Rural areas had 13.8 surgeons per 100,000 residents versus 23.6 per 100,000 in metropolitan areas. Surgeons graduating in 2010 or later had approximately half the odds of rural practice compared with those graduating in 1979 or earlier (adjusted OR, 0.48; 95% CI, 0.42–0.56). Conclusions: Osteopathic surgeons disproportionately practice in rural and socioeconomically disadvantaged communities, identifying an important workforce component for maintaining rural surgical access. The declining likelihood of rural practice among more recent training cohorts raises concerns regarding the future rural surgical workforce.

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.

Abstract Background There is limited data on immune checkpoint inhibitor (ICI) use in patients with non-small cell lung cancer (NSCLC) and known pericardial effusions. Methods This international multi-center observational retrospective study included patients with advanced NSCLC with or without pericardial effusions receiving ICIs. Immune-related adverse events (irAEs) were graded per CTCAE v5.0. Overall survival (OS) and progression-free survival (PFS) were estimated by the Kaplan-Meier method. Cox proportional hazards multivariable models assessed the association between survival outcomes and clinicopathologic variables, and an inverse probability of treatment weighting (IPTW) model compared outcomes between the two groups. Results A total of 1248 patients with advanced NSCLC treated with ICIs across 13 institutions were included. Of these, 85 patients (6.8%) had pre-existing pericardial effusions. Compared to controls, patients with pericardial effusions were younger (median age 63 vs 67 years, P = .007), diagnosed more frequently with PD-L1 positive tumors (96% vs 76%, P &lt; .001), and had a higher median number of baseline metastatic sites (3 vs 1, P &lt; .001). IrAEs were similar between both groups (42% vs 38%), and no cardiac irAEs occurred in patients with pericardial effusions. PFS (median 5.6 vs 4.6 months, P = .3) and OS (median 10.2 vs 14.7 months, P = .50) were not statistically different between patients with pericardial effusions and the controls, respectively. In both multivariable and IPTW models, pericardial effusions were not associated with PFS or OS. Conclusions Among patients with NSCLC and pre-existing pericardial effusions, ICIs demonstrate meaningful clinical benefit similar to those without effusions, with no new cardiac or severe toxicities.
