Background: The study aims to evaluate the postoperative outcomes of hiatal hernia repair with cruroplasty alone compared to the addition of fundoplication. We theorize that previously reported inferiority with crural-only repairs resulted from a lack of real-time feedback regarding the effectiveness of the repair. EndoFLIP TM allows for intraoperative assessment of the gastroesophageal junction. We predict equivalent postoperative outcomes will be achieved between hiatal hernia repairs performed by cruroplasty alone and with fundoplication when the final distensibility index (DI) is similar. Methods: This retrospective cohort review includes patients who underwent hiatal hernia repair with intraoperative EndoFLIP TM between 2020 and 2022. Propensity score-matching was utilized to identify cruroplasty alone and fundoplication patients with a final DI within 0.5 mm 2 /mmHg of one another. Postoperative development of dysphagia, reflux, or hernia recurrence were primary outcomes of interest. Results: Forty-two patients were included in the analysis. While the cruroplasty-alone cohort had an increased age at the time of surgery, 50% more redo repairs, and a slightly higher BMI, there were no significant preoperative or intraoperative differences between groups. Overall, the median duration of follow-up was 111 (IQR 213) days. During that time, there were no differences in the development of postoperative reflux or dysphagia between cohorts ( P = .228 and P = .451, respectively). Kaplan-Meier curve analysis did not demonstrate a significant difference in time-to-event for either outcome. There were 3 radiographic recurrences, with 2 occurring after fundoplication ( P = .000). Conclusions: This is the first study to utilize intraoperative EndoFLIP TM to determine the need for fundoplication during hiatal hernia repair. The results demonstrate no additional short-term benefit from fundoplication performance. These findings argue against routine fundoplication when an acceptable DI can be achieved after cruroplasty. Further research is needed to validate these results.

Immune checkpoint inhibitors (ICIs) have transformed cancer therapy but are associated with immune-related adverse events, including ICI–associated acute kidney injury (ICI-AKI). ICI-AKI presents diagnostic and management challenges and can influence decisions regarding immunosuppression and ICI rechallenge, with important implications for both kidney and cancer outcomes. An international, multidisciplinary panel convened at the 34th Acute Disease Quality Initiative (ADQI) consensus conference in September 2024. Systematic literature searches of PubMed were conducted to identify studies on the epidemiology, mechanisms, diagnosis, management, rechallenge, and outcomes of ICI-AKI. The meeting followed the established ADQI process and used a modified Delphi method to achieve consensus. Evidence was reviewed and appraised by workgroups, and consensus statements were developed through structured discussion and voting. Observational data suggest that AKI occurs in up to 20% of patients receiving ICIs, with ICI-AKI accounting for approximately 2%–5% of cases. Acute tubulointerstitial nephritis is the most common lesion, observed in 80%–90% of biopsies, although glomerular diseases are increasingly recognized. No clinical features reliably distinguish ICI-AKI from other causes of AKI, and kidney biopsy remains the diagnostic gold standard. Emerging urinary, circulating, and imaging biomarkers show promise but are not yet ready for routine clinical use. Early glucocorticoid initiation (within 3 days of ICI-AKI diagnosis versus >3 days after diagnosis) is associated with higher rates of kidney recovery, although optimal dosing and duration remain uncertain. Recurrent ICI-AKI occurs in fewer than 20% of patients undergoing ICI rechallenge. Management of high-risk populations, including kidney transplant recipients and patients with autoimmune disease or advanced CKD, requires individualized, multidisciplinary decision-making. ICI-AKI is an important and potentially reversible complication of cancer immunotherapy; these consensus statements provide a framework for diagnosis and management, support cautious ICI rechallenge in selected patients, and identify priorities for future research.

The total number of total hip arthroplasties performed each year is expected to increase significantly over the coming decades. As a result, an increasing number of young patients are undergoing total hip arthroplasty while similarly, a growing subset of active elderly patients desire to return to sports or high-impact activity after surgery. Patients are typically provided restrictions and activities to avoid following surgery. For these patients, there is no clear consensus or guidelines regarding whether they should limit their activity level postoperatively and in particular, if returning to high-impact exercise increases their risk of complications and subsequent revision surgery. This article will discuss the most common complications after total hip arthroplasty and whether patients who return to sports or a high-impact activity after surgery may be more predisposed to these complications in comparison to their more sedentary peers.

Abstract Background Existing formal feedback systems in graduate medical education often rely heavily on intangible Likert Scales linked to ACGME milestones as an end-of-rotation summative assessment. However, more frequent, actionable, formative feedback based on observations is essential to personal growth. Objective To evaluate the impact of changing from a milestone-based evaluation form to a brief narrative-based feedback form in a Pulmonary Disease and Critical Care Medicine (PCCM) fellowship as an exploratory pilot project. Our aim was to describe change in perception of feedback quality and the impact on Clinical Competency Committee (CCC) decisions. Methods We compared the quality of written rotation feedback before and after implementing a shorter feedback form on January 1, 2024 for 15 PCCM fellows at a single large academic institution using the Quality of Assessment for Learning (QuAL) score, (July 2023-December 2023 compared to January 2024-July 2024), fellow pre- and post-surveys (December 2023 and June 2024) and a CCC focus group (June 2024). Results Overall QuAL score improved significantly after narrative-based feedback form implementation (2.71 pre [n = 75] vs 3.70 post [n = 85], p < 0.001). Surveys had 13/14 (92.8%) fellows respond pre-intervention and 8/14 (57.1%) post-intervention. There was significant improvement in the number of fellows indicating they could identify new learning goals based on written feedback after implementation of the new form (23.1% pre vs 75.0% post, p = 0.03). The CCC focus group with 5 of 8 eligible faculty participating described milestone decisions were better supported by more detailed narratives. Conclusions Implementing a brief narrative-based form improved feedback quality and the number of trainees able to create learning goals. The CCC identified that the new form provided better details to support milestone recommendations.

Urinary urea is a key biomarker for tracking protein oxidation and nitrogen balance. A persistent analytical limitation is that conventional total-nitrogen assays do not deconvolute urinary urea from urinary ammonia, and direct measurement still requires capital-intensive clinical analyzers. Here, we implement and independently validate two cost-effective methods that resolve urinary urea by pairing the presence and absence of urease: Method 1 is a urease-coupled potentiometric assay using an ammonium ion-selective electrode (ISE method); Method 2 is a microplate Berthelot–salicylate colorimetric assay employing a repurposed consumer-grade aquarium ammonia test kit (API®) (API method). Each method was validated against the Roche Cobas C311 clinical analyzer (ISE for urinary ammonia and API for urinary urea) in healthy adult volunteers (n = 10 each), and API–ISE were then compared head-to-head for urinary urea. ISE vs. Cobas yielded R2 = 0.967, slope 95% CI [0.867, 1.173], and Bland–Altman bias of −1.02 mM (95% LoA [−7.40, +5.36] mM). API vs. Cobas yielded R2 = 0.973, slope 95% CI [0.790, 1.039], and bias of −1.55 mM (95% LoA [−11.56, +8.46] mM). API–ISE urinary urea comparison confirmed mutual agreement (R2 = 0.9976, slope 95% CI [0.946, 1.024]; bias of +3.47 mM; 95% LoA [−14.60, +21.53] mM), with mean recoveries near 100% (API: 100.7 ± 2.9%; ISE: 100.6 ± 5.4%; 20–350 mM). Both methods agreed with the clinical analyzer, supporting their potential for decentralized, resource-limited testing; clinical and point-of-care validations are needed.

Abstract Background: Glioma diagnosed during pregnancy and pregnancy following glioma treatment present complex management challenges. The safety of glioma treatment during pregnancy is not well established. The ability to counsel patients on timing of conception after treatment remains limited. The aim of this study was to review our institution’s experience with glioma during and before pregnancy. Methods: In this single-institution study, we retrospectively identified patients diagnosed with glioma during or prior to pregnancy and reviewed treatment course and maternal and neonatal outcomes. Results: Twenty-one female patients were included in our study. Glioma diagnoses included 12 high-grade tumors and 9 low-grade tumors. Cohort A consisted of 8 patients who presented with glioma during pregnancy, of which, 7 underwent glioma treatment during pregnancy. All pregnancies in cohort A were without significant maternal complications and resulted in delivery of a healthy neonate. Cohort B consisted of 13 patients who experienced pregnancy after a prior diagnosis of glioma, totaling 23 pregnancies. Antepartum course was complicated by seizure in three pregnancies. Functionally inconsequential anatomic abnormalities in childhood offspring of cohort B occurred in 5 (27.8%) of the pregnancies. Four of the offspring with anatomic abnormalities had exposure to TMZ prior to conception. Conclusions: In this retrospective series, diagnosis of glioma before or during pregnancy was associated with generally favorable maternal, fetal and childhood outcomes. We observed a higher-than-expected rate of anatomic abnormalities in the post-diagnosis cohort, though none carried meaningful functional consequences. These findings add to the limited literature exploring maternal and fetal outcomes in patients with glioma.

Abstract Oxidative phosphorylation (OXPHOS) is a central function and a key indicator of mitochondrial fitness, yet studies in human tissue remain limited. Inclusion body myositis (IBM) is a progressive myopathy that lies at the intersection of aging, inflammation and mitochondrial dysfunction. We aimed to perform a comprehensive profiling of mitochondrial respiration in muscle tissue from patients with IBM. A wide battery of complementary approaches from RNA level to high-resolution respirometry on permeabilized muscle fibers was employed. The relationship between mitochondrial respiration, mitochondrial content, mitochondrial DNA (mtDNA) abnormalities and mitophagy was examined, along with the correlation with various clinical parameters to determine their clinical relevance. The study included a total of 67 patients with IBM and 45 controls. On high resolution respirometry of permeabilized muscle fibers, IBM samples exhibited reduced maximal mitochondrial respiration per tissue weight in State 3 (high substrates, high ADP) and uncoupled state with decreased coupling efficiency and higher leak control ratios. When adjusting for citrate synthase reflecting mitochondrial content, male patients had decreased State 3 intrinsic respiration, whereas female patients had greater intrinsic respiration under leak states. Complex I activity was decreased mainly in female patients, in whom complex II control ratio positively correlated with disease duration and severity. IBM was further associated with decreased RNA levels of all complexes, and lower protein expression of complex I, III, IV and V, likely related to the lower mtDNA content seen in IBM samples. Regarding the production of reactive oxygen species, IBM samples exhibited lower maximal H2O2 emission, accompanied by a higher total antioxidant capacity that positively correlated with disease duration in female patients. Lastly, correlation analyses suggested that impaired mitochondrial respiration, altered mitophagy, and reduced mtDNA content are interconnected in IBM and maybe of clinical significance. IBM is characterized by multifaceted, clinically relevant impairments in mitochondrial respiration. Future studies should further explore underlying pathomechanisms and the variation of mitochondrial respiration by disease stage.
