Background: Hypoparathyroidism (HypoPT) is a rare endocrine disorder that requires close evaluation and follow up during pregnancy to minimize maternal and fetal complications. The primary objectives of this study are to evaluate the use of rhPTH (1-84) during pregnancy by analyzing data from the PARADIGHM disease registry, and to compare maternal and neonatal outcomes among patients who continued PTH therapy during pregnancy versus those on conventional therapy (CT). Methods: We performed a retrospective analysis of data in the PARADIGHM registry. Maternal and neonatal outcomes in women treated with rhPTH (1-84) were compared to women who received CT. Results: We analyzed 39 pregnancies of 32 women. Of those, 4 women (6 pregnancies) used rhPTH (1-84) either before or during pregnancy and 28 women (33 pregnancies) continued CT during pregnancy. The mean (SD) maternal age at enrollment was 31.7 (5.6) years. Postsurgical HypoPT was the most common etiology (68.8%). The mean gestational age at delivery was 36 (2.4) weeks (PTH-treated) vs 38.3 (3.3) weeks (CT) (p=0.162). Preterm delivery rates were higher in the PTH-treated group (50% vs. 27%, p=0.591), but this was not statistically significant. Two women had pre-eclampsia, one in each group (PTH-treated and CT). In the PTH-treated group, one pregnancy resulted in a stillbirth, and one infant was born with congenital anomalies (16.7% each). Conclusions: The safety of rhPTH (1-84) use in pregnancy cannot be determined at this time. The PTH-treated group exhibited trends towards higher rates of preterm delivery, but the rates of stillbirth, and congenital anomalies were low and comparable in both groups of women. Larger studies are necessary to determine the optimal approach to manage women with HypoPT during pregnancy. Presentation: Sunday, July 13, 2025

Goals: This study aimed to assess perspectives and practices among expert gastroenterologists regarding the screening, diagnosis, and management of BE. Background: Significant variability in the management of Barrett’s esophagus (BE) persists among physicians despite the development and dissemination of several clinical practice guidelines. Study: An online survey was conducted with 38 expert gastroenterologists specializing in BE management. The 38-question survey evaluated demographics, medical management, and attitudes toward endoscopic treatment, with responses analyzed for trends and variations. Results: Of the 38 experts, 34 (89%) responded. Respondents were primarily male (85%), with 82% affiliated with academic hospitals and 53% clinically focused on BE. Half discussed BE risks during initial consultations for gastroesophageal reflux disease (GERD). Most (61.8%) agreed BE should be considered in women with chronic GERD, and 88.2% regularly used narrow-band imaging (NBI). However, 44% were neutral or disagreed with diagnosing BE based solely on community gastroenterologist biopsies, and acceptance of Wide-Area Transepithelial Sampling with 3D Analysis (WATS-3D) for Barrett’s esophagus diagnosis and surveillance was limited. Fifty-three percent recommended ablation for nondysplastic BE. Fifty-two percent recommended indefinite daily PPI therapy after complete eradication of intestinal metaplasia (CEIM), regardless of symptoms. When encountering cardia intestinal metaplasia after endoscopic eradication, 38% recommended ablation, while 47% continued surveillance. Conclusion: This study highlights substantial variations in the management of BE among expert gastroenterologists, despite the existence of updated guidelines. Identifying these discrepancies is crucial for optimizing care. Further efforts are needed to standardize practices and enhance the implementation of evidence-based guidelines in clinical settings.

Abstract Objective To evaluate available evidence for the efficacy and safety of topical analgesics for neuropathic pain and to offer treatment guidance. Methods An expert panel searched PubMed (Medline) and reference lists of published articles for available literature assessing 8 categories of topical analgesics used to treat various neuropathic pain conditions. The panel rated the level of analgesic efficacy evidence for each treatment and considered safety, ease of use, and cost. The degree of consensus on the recommendations among the panelists was measured. Results There was strong evidence and high consensus that capsaicin 8% is effective for diabetic peripheral neuropathy and postherpetic neuralgia and that lidocaine is effective for postherpetic neuralgia. There was strong evidence and moderate consensus that capsaicin 8% could be effective for HIV-induced neuropathy. There was moderate evidence and high consensus that lidocaine is likely effective for diabetic peripheral neuropathy, idiopathic neuropathy, and postsurgical neuropathy and that capsaicin 8% might be effective for chemotherapy-induced peripheral neuropathy and complex regional pain syndrome. Evidence was weak for other topical medications, though the panel strongly agreed that antidepressants might help with postherpetic neuralgia, complex regional pain syndrome, postsurgical neuropathy, and post-traumatic neuropathy; that nonsteroidal anti-inflammatory drugs could help with postsurgical neuropathy; and that gabapentin might benefit vulvodynia. There was less agreement about whether antidepressants might benefit diabetic peripheral neuropathy, chemotherapy-induced peripheral neuropathy, and vulvodynia and whether capsaicin 8% could be effective for postsurgical neuropathy. Conclusions Recommendations were based on a survey and grading of existing literature and, when strong evidence was lacking, the collective clinical expertise of panelists.

Abstract Objective The objective of this study is to characterize contemporary surgical management practices and factors influencing surgical decision‐making in the management of Lennox–Gastaut Syndrome (LGS) across pediatric epilepsy centers in the United States. Methods A 45‐item cross‐sectional survey was developed and distributed to Pediatric Epilepsy Research Consortium centers. Domains included institutional demographics, surgical evaluation timing and goals, presurgical workup, procedural utilization and outcomes, and barriers to surgery. Descriptive statistics and thematic analysis were performed. Results Thirty‐two pediatric epilepsy centers participated (38% response), the majority comprising pediatric epileptologists at Level 4 National Association of Epilepsy Centers. Most centers (66%) considered surgery after failure of 3–4 antiseizure medications. Presurgical workup typically included brain magnetic resonance imaging (MRI), long‐term electroencephalography (EEG) monitoring, and neuropsychological assessment, while use of functional imaging, magnetoencephalography, and intracranial EEG varied considerably. All centers offered vagus nerve stimulation and corpus callosotomy; 80%–90% offered resection, hemispherectomy, responsive neurostimulation (RNS); 60%–65% offered deep brain stimulation (DBS) and laser ablation. Among centers offering RNS, half targeted thalamic structures exclusively, and the remainder targeted cortical or combined cortical‐thalamic structures; the centromedian nucleus was the preferred thalamic target for RNS and DBS. Surgical decision‐making was influenced by patient characteristics, procedural considerations, and systemic factors. Seizure frequency, family preference, and multidisciplinary input were highly rated across all interventions. Etiology was critical for resection and hemispherectomy, while financial constraints, insurance barriers, and the need for future neuroimaging impacted neuromodulation selection. Scenario‐specific trends included less frequent consideration of DBS and RNS in children under five years, less use of hemispherectomy in older children, preference for corpus callosotomy in children with predominantly drop seizures, and procedural selection based on MRI findings. Significance Substantial variability exists in the surgical management of LGS. These findings highlight critical opportunities to harmonize practices, reduce disparities, and guide comparative effectiveness research to optimize outcomes. Plain Language Summary Lennox–Gastaut Syndrome (LGS) is a severe form of epilepsy that may require surgery when medications are not effective. This study found that surgical care for LGS varies widely across pediatric epilepsy centers in the United States, including when surgery is recommended, how patients are evaluated, and which procedures are available. Newer approaches such as brain stimulation are being used more often, although access remains inconsistent. These findings highlight the need for clearer treatment pathways to ensure that children with LGS have equitable access to the best possible care.

Importance Multiparametric magnetic resonance imaging (MRI), with or without prostate biopsy, has become the standard of care for diagnosing clinically significant prostate cancer. Resource capacity limits widespread adoption. Biparametric MRI, which omits the gadolinium contrast sequence, is a shorter and cheaper alternative offering time-saving capacity gains for health systems globally. Objective To assess whether biparametric MRI is noninferior to multiparametric MRI for diagnosis of clinically significant prostate cancer. Design, Setting, and Participants A prospective, multicenter, within-patient, noninferiority trial of biopsy-naive men from 22 centers (12 countries) with clinical suspicion of prostate cancer (elevated prostate-specific antigen [PSA] level and/or abnormal digital rectal examination findings) from April 2022 to September 2023, with the last follow-up conducted on December 3, 2024. Interventions Participants underwent multiparametric MRI, comprising T2-weighted, diffusion-weighted, and dynamic contrast–enhanced (DCE) sequences. Radiologists reported abbreviated biparametric MRI first (T2-weighted and diffusion-weighted), blinded to the DCE sequence. After unblinding, radiologists reported the full multiparametric MRI. Patients underwent a targeted biopsy with or without systematic biopsy if either biparametric MRI or multiparametric MRI was suggestive of clinically significant prostate cancer. Main outcomes and measures The primary outcome was the proportion of men with clinically significant prostate cancer. Secondary outcomes included the proportion of men with clinically insignificant cancer. The noninferiority margin was 5%. Results Of 555 men recruited, 490 were included for primary outcome analysis. Median age was 65 (IQR, 59-70) years and median PSA level was 5.6 (IQR, 4.4-8.0) ng/mL. The proportion of patients with abnormal digital rectal examination findings was 12.7%. Biparametric MRI was noninferior to multiparametric MRI, detecting clinically significant prostate cancer in 143 of 490 men (29.2%), compared with 145 of 490 men (29.6%) (difference, −0.4 [95% CI, −1.2 to 0.4] percentage points; P = .50). Biparametric MRI detected clinically insignificant cancer in 45 of 490 men (9.2%), compared with 47 of 490 men (9.6%) with the use of multiparametric MRI (difference, −0.4 [95% CI, −1.2 to 0.4] percentage points). Central quality control demonstrated that 99% of scans were of adequate diagnostic quality. Conclusion and relevance In men with suspected prostate cancer, provided image quality is adequate, an abbreviated biparametric MRI scan, with or without targeted biopsy, could become the new standard of care for prostate cancer diagnosis. With approximately 4 million prostate MRIs performed globally annually, adopting biparametric MRI could substantially increase scanner throughput and reduce costs worldwide.

Background: The Centers for Medicare & Medicaid Services (CMS) Merit-based Incentive Payment System (MIPS) has undergone numerous changes to promote care for patients at high social risk. However, the effect of these changes on surgeon MIPS performance and caseload selection remains unclear. Thus, the purpose of this study was to evaluate how orthopaedic surgeon MIPS scores, demographics, practice characteristics, and patient populations varied on the basis of patient social risk in 2017 compared with 2021. Methods: CMS data were utilized to examine U.S. orthopaedic surgeons. Surgeons were placed into social-risk quintiles on the basis of the proportion of their patients who were dually eligible for Medicare and Medicaid, with the highest quintile representing the highest social risk. Demographics, practice location characteristics, patient data, and MIPS performance were assessed for the years 2017 and 2021. Differences between social-risk quintiles were assessed utilizing chi-square, Student t, and Wilcoxon signed-rank tests and multivariable logistic regression. Results: In 2017, surgeons with caseloads at the highest, compared with the lowest, social risk had lower MIPS performance scores (mean [and standard deviation], 66.0 ± 37.6 versus 70.1 ± 33.5; p < 0.001). However, in 2021, orthopaedic surgeons with caseloads at the highest, compared with the lowest, social risk had significantly higher MIPS performance scores (mean, 88.7 ± 16.9 versus 81.5 ± 18.3; p < 0.001). In terms of demographics, in 2021, orthopaedic surgeons with caseloads at the highest, compared with the lowest, social risk were more often women (9.2% versus 3.6%; p < 0.001), more often had a DO degree (11.2% versus 6.6%; p < 0.001), more recently graduated from medical school (mean, 23.0 ± 12.9 versus 25.7 ± 10.9 years; p < 0.001), and worked in areas with higher Distressed Communities Index (DCI) distress scores (mean, 56.9 ± 27.3 versus 35.1 ± 25.2; p < 0.001). Similar findings were present in 2017. Conclusions: The addition of the Complex Patient Bonus to the MIPS in 2020 may have reduced performance inequities in MIPS scoring for surgeons with caseloads at high social risk. However, the demographics and practice patterns of the orthopaedic surgeons caring for populations at the highest social risk remained consistent between years. Level of Evidence: Prognostic Level III . See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT Bipolar disorder’s (BD) clinical heterogeneity has an unresolved genetic basis. We meta-analyzed genome-wide association studies (GWAS) of 16 BD subphenotypes in 226,032 individuals from 57 cohorts (38,022 cases); 10 advanced to multivariate and multi-trait analyses. Four factors (compulsive, psychotic, dysregulated, internalizing) explained 82.8% of shared genetic variance. BD1 and BD2 loaded on distinct factors despite a high genetic correlation; 87.0% of common-factor loci were significant in neither subtype. Unipolar mania aligned with psychosis over internalizing, and was distinguishable from BD1, and rapid cycling showed heritable cross-domain liability. We identified 356 risk loci, 158 novel, including the first univariate-GWAS associations for psychosis, unipolar mania, rapid cycling and schizoaffective disorder—and 249 credible genes (89 high-confidence), 12 with approved-drug or clinical-phase annotations. Cell-type association showed a midbrain dopaminergic–GABAergic gradient along the psychotic factor. BD’s genetic architecture appears hierarchical—a general liability resolving into dimensions of course and comorbidity beyond diagnostic subtypes.

Study Design This study is part of the AO Spine Metastatic Tumor Research and Outcomes Network [MTRON], an international multicenter prospective observational registry including patients with spinal metastases. Objectives This study aims to elucidate the incidence of surgical complications, their risk factors and consequent effects on survival outcomes, hospital length of stay, and overall health-related quality of life (HRQOL) parameters in a large cohort of patients affected by spinal metastases who were surgically treated. Methods Available data from February 2017 to July 2023 were analyzed. The primary outcome of this study was the evaluation of the incidence of intraoperative and postoperative adverse events (AEs). The secondary outcomes included the assessment of risk factors for surgery-related AEs and the impact of AEs on survival, length of hospital stay and quality of life. Results Among the 1267 patients analyzed, 6.9% experienced intraoperative AEs and 19.3% experienced at least 1 postoperative AE. Several factors resulted to be associated to the occurrence of postoperative AEs: age, smoking habit, poor Eastern Cooperative Oncology Group (ECOG) Performance status, previous radiation therapy at the index target, duration of surgery, number of instrumented levels, simultaneous anterior and posterior approach, presence of metastases at other sites, multiple spinal metastases. Postoperative AEs were associated with reduced survival rates, increased hospital length of stay and poorer HRQOL outcomes, particularly in domains such as neurological function and mental health. In general, surgery substantially improves HRQOL across multiple domains, with these benefits persisting over time despite the occurrence of AEs. However, patients with preoperative risk factors, including comorbidities, smoking, neurological impairment, and prior radiation therapy, experienced less improvement. Conclusions The negative impact of AEs on overall survival and HRQOL could be associated with the presence of some preoperative parameters of frailty that are detected as risk factors for AEs occurrence. This finding emphasizes the need for personalized preoperative assessments and optimized perioperative care strategies.
