We report a rare case of biliary aplasia in an infant who presented with persistent jaundice and elevated direct bilirubin despite having cholic stools. Imaging confirmed the absence of extrahepatic bile ducts, consistent with biliary atresia. Intraoperatively, there was a complete absence of an extrahepatic biliary tree consistent with biliary hypoplasia. We identified a cryptogenic hepatic plate directly fused to the right portal vein on further dissection. Despite the atypical anatomy, a modified Kasai portoenterostomy was successfully performed. The patient showed progressive clinical improvement with complete resolution of jaundice and normalisation of liver function tests over the following months. This case underscores a rare anatomical variant that can still permit a favourable outcome with a timely Kasai procedure. To our knowledge, this is one of the few documented cases of hepatic plate–portal vein fusion in biliary atresia.

Abstract Background Completing adjuvant chemotherapy and reducing toxicities are critical for maximizing survival after a colon cancer diagnosis. Sex, as a biological variable, may affect colon cancer chemotherapy completion, toxicities, and survival differently. Methods From a National Cancer Institute–sponsored trial conducted among patients with stage III colon cancer (Cancer and Leukemia Group B (Alliance)/Southwest Oncology Group 80702), we included 2201 patients receiving the standard adjuvant chemotherapy regimen of fluorouracil, leucovorin, and oxaliplatin. We calculated relative dose intensity to indicate chemotherapy completion and considered reduced relative dose intensity (values <85%) as a clinically significant deviation from standard fluorouracil, leucovorin, and oxaliplatin. Using National Cancer Institute’s Common Terminology Criteria for Adverse Events, we defined severe adverse events (grade ≥3) as the occurrence of any following event, including neutrophil count decrease, nausea, platelet count decrease, hypertension, peripheral neuropathy, diarrhea, fatigue, gastritis, creatinine level increase, gastric ulcer, myocardial ischemia, and cerebral ischemia. The primary survival outcome was disease-free survival (time from enrollment to colon cancer recurrence or death from any cause), and secondary survival outcomes were recurrence-free and overall survival. Results Compared with men, women were at statistically significantly higher risks of experiencing reduced relative dose intensity (adjusted odds ratio = 1.59, 95% CI = 1.29 to 1.96; P < .001) and severe advance events (adjusted odds ratio = 1.72, 95% CI = 1.41 to 2.11; P < .001). Yet, women had statistically significantly better disease-free survival (adjusted hazard ratio = 0.72, 95% CI = 0.59 to 0.87; P < .001) as well as better recurrence-free and overall survival. Conclusions Our findings suggested that women with colon cancer are more likely to have worse chemotherapy completion rates and more severe adverse events, but they have better survival. Sex as a biological variable warrants further consideration in chemotherapy administration and survivorship management after colon cancer diagnosis.

ABSTRACT Background Up to 20% of patients with antineutrophil cytoplasmic antibody–associated vasculitis (AAV) and kidney involvement progress to end-stage kidney disease (ESKD) despite therapy. The role of monoclonal gammopathy (MG) in disease progression in patients with AAV is not well understood. Methods We conducted a retrospective study to identify patients diagnosed with AAV and renal involvement who had undergone monoclonal protein testing between November 1999 and December 2023. A total of 167 patients were included in the renal survival analysis and were categorized into monoclonal positive (n = 34) and monoclonal negative (n = 133) groups. For the mortality analysis, we expanded the cohort to include an additional 26 patients who were dialysis-dependent at baseline and remained on dialysis throughout follow-up, resulting in a total of 193 patients. We performed multivariate Cox analysis to identify predictors of adverse renal events [>40% decline in estimated glomerular filtration rate (eGFR) or ESKD (eGFR <15 mL/min/1.73 m², need for dialysis or transplantation)] and mortality. Results Median age of the cohort was 68 (58.5–74.5) years, with 50.8% males, 65.8% MPO positive, and 64.6% receiving rituximab as induction therapy. After adjusting for baseline proteinuria, sclerotic Berden class and induction therapy, MG was associated with adverse renal events [hazard ratio (HR) 3.29 (95% confidence interval 1.12–9.68), P = .03]. MG at baseline was not associated with mortality [HR 1.65 (0.87–3.12), P = .12], however patients with persistent MG at 6 months had higher mortality compared with those without MG or those whose MG was not sustained [HR 3.95 (1.10–14.21), P = .035]. Conclusions Patients with AAV and renal involvement who have MG are at significantly increased risk of adverse renal events even after adjusting for factors such as eGFR and degree of chronicity (known predictors of poor renal outcome). The exact mechanism by which MG portends poor outcomes is poorly understood, and additional research is required.

Abstract Background Breast cancer (BC) survivors frequently experience sleep disturbances, which may persist for many years after treatment. This study aimed to describe trends in sleep-related symptoms over time and identify factors that may be associated with sleep disturbances in BC survivors. Patients and Methods Adult patients from the Mayo Clinic Breast Disease Registry were surveyed annually for up to 7 years post-diagnosis. Sleep disturbance severity was assessed using numeric rating scales for difficulty falling and staying asleep. Data from 3354 unique patients were analyzed, excluding those with metastatic disease or recurrence. Univariable and multivariable analyses were performed at the 1-year survey timepoint to evaluate disease and patient-related factors that were associated with increased sleep-related symptoms, and these factors were also assessed in relationship to sleep-related symptoms over time. Results In multivariable analyses, more trouble falling asleep was associated with financial insecurity, higher clinical stage, more cigarettes smoked per day, and less weekly exercise. More trouble staying asleep was associated with older age, race, advanced education, financial insecurity, and higher clinical stage. Over time, there was a nonsignificant trend toward increased trouble falling asleep and fluctuations in trouble staying asleep. Higher clinical stage and receipt of radiotherapy were associated with decreased severity in trouble falling asleep over time, while more cigarettes smoked per day was linked to increased severity in trouble staying asleep. Conclusions These findings highlight the complex interplay of clinical, lifestyle, and demographic factors in sleep disturbances among BC survivors, underscoring the need for tailored sleep management strategies.

Abstract Background Unresectable hepatocellular carcinoma (uHCC) is a leading cause of cancer death. FDA-approved first-line systemic therapies include atezolizumab/bevacizumab (atezo/bev) and durvalumab/tremelimumab (durva/treme); however, there is a lack of comparative data. Methods We reviewed outcomes of patients with uHCC who initiated atezo/bev or durva/treme between 2017 and 2024, across six institutions. Overall survival (OS) and time to treatment discontinuation (TTD) were analyzed using the Kaplan–Meier and Cox models, adjusting for baseline characteristics. Results Four hundred fifty-two uHCC pts were included. Median age: 68 years; 77% male; 81% white. Most common etiologies were viral hepatitis (38.9%) and metabolic dysfunction-associated steatohepatitis (19.5%). Disease progression was the primary reason for treatment discontinuation, atezo/bev (56%) and durva/treme (42%). Outcomes were not statistically significant (median OS [month, m]: 14.0 vs 14.6 [P = .66]; median TTD [m]: 4.9 vs 3.9 [P = .42] for atezo/bev vs durva/treme). Outcomes were significantly different between Child-Pugh classes (CP: A, B7, B8/9, C) respectively, median OS(m): 19.0, 6.1, 5.1, 2.0 (P < .001); median TTD(m): 6.1, 2.3, 3.0, 1.3 (P < .001). Conclusions In this real-world study of uHCC, no significant difference in clinical outcomes was observed between atezo/bev and durva/treme in the first-line setting. CP scores were a key prognostic variable with both regimens.

Background Telestroke emergency department (ED) workflow emulates that of in-person care, yet limitations of the virtual interaction may require accommodations. The optimal sequence of non-contrast head CT, cerebral CT angiogram, and decision to infuse IV thrombolytic is not defined for telestroke. Methods In this twenty-two-hospital multicenter retrospective study between 1/1/2024-12/31/2024, we characterized timing of ED CT angiograms, either bundled with the non-contrast head CT or non-bundled and performed after the IV-thrombolytic decision. The primary outcome was effect of bundling on door to needle time (DTN) when directed by telestroke. Timing of CT scans was determined by time stamps of scout images. Results In total, 5704 patients were included, with a median age of 65 years (Interquartile range, IQR 58-77) and NIHSS 8 (IQR 6-13). There were 4518 patients in the bundled group (n = 12 hospitals), with time from non-contrast CT to CTA of median 2 min (IQR 0-6 min; vs non-bundled (n = 10 hospitals): 7, 4-15 min; P = .0001). DTN was not statistically different between the groups, bundled vs not: median 47 min (IQR, 35-62 min) vs 54 min (IQR, 41-67 min, P = .21). Door in door out (DIDO) times also were unchanged (169, 117-254 vs 175, 123-247 min; P = .56). These findings, although showing no statistical difference, may have significance for clinical workflows and were consistent with the results of validation analyses conducted on individual patients. Conclusions Bundling non-contrast head CT with the CT angiogram before thrombolytic decision did not delay DTN times, trended to clinically improve times, and may be relevant for telestroke ED workflows.

Abstract Importance The addition of agents targeting critical signal mediators of cancer cell proliferation such as cyclin-dependent kinases (CDK) potentiates the efficacy of platinum chemotherapy. Objective To determine the safety and efficacy of palbociclib combined with cisplatin (cis) or carboplatin (carbo) in advanced solid malignancies Design Enrollment on dose escalation (part I) proceeded using the Bayesian adaptive design Escalation with Overdose Control (EWOC). Setting Single institution investigator initiated trial. Participants Patients with any advanced cancer after at least one prior therapy were enrolled on dose escalation to determine recommended phase II doses (RP2D). Expansion cohorts were then opened for pancreaticobiliary tract cancers. Intervention Escalating doses of palbociclib in combination with different doses of cisplatin or carboplatin. Main Outcomes and Measures Primary endpoint was objective response rate (ORR). Secondary endpoints included safety, overall survival (OS), and progression-free survival (PFS). Results We enrolled 39 patients on dose escalation (part I) and 32 additional patients on dose expansion (part II). RP2D of palbociclib 100 mg on Day 2-22 + Cisplatin (cis) 60 mg/m2 IV on Day 1 Q4W (Arm A); and palbociclib 75 mg on Day 2-22 + Carboplatin (carbo) AUC 6 IV on Day 1 Q4W (Arm B). ORR for Part I were 12.5% (Arm A) and 25% (Arm B). Median PFS and OS for dose expansion were 2.1 and 4.9 months, respectively. For PDAC, mPFS was 1.9 months (95% CI: 1.7, 2.4), and OS was 3.7 months (95% CI: 2.7, 5.7). Most common treatment-related adverse events (TRAEs—all grade %): Arm A—neutropenia (66%), thrombocytopenia (26%), nausea, fatigue, and anemia (20% each); Arm B—neutropenia (64.7%), thrombocytopenia (53%), and anemia (29%). There were no grade 4-5 TRAEs. Conclusions and Relevance The combination of palbociclib with cisplatin or carboplatin had an acceptable safety profile and clinical responses in some treatment refractory advanced cancers. There was no objective response, but about half of PDAC patients had disease stabilization. Additional efforts are needed to exploit CDK abnormalities in these patients.

ABSTRACT Traumatic brain injury (TBI), particularly among military personnel, poses significant challenges in acute management and long-term outcomes. Difficult-to-diagnose autoregulatory and inflammatory changes lead to neurocognitive impairment, anxiety, sleep disturbance, and chronic pain. To optimize readiness and test therapeutics for both diagnostic and future TBI treatments, this feasibility study introduces a novel wearable multimodal platform that integrates photoplethysmography and infra-red (IR) sensing from a camera and a wearable sensor to detect vital signs and then leverages machine learning (ML) to predict the need for acute treatment. This prospective observational study involving 28 healthy volunteers simulated a triage emergency room workflow to test sensor accuracy and mobile app functionality. The wearable device demonstrated high accuracy in pulse rate (mean error 7.3%) and oxygen saturation (mean error −1.2%) compared to standard-of-care devices. Camera-based pulse and respiratory rate, and wearable pulse, oxygen, and temperature sensing were tested in a mock triage setting to simulate activation of light-based treatment upon detection of physiological changes of concern after acute TBI. Preliminary ML models to predict hypotension and pain based on retrospective data achieved 98.4% and 93% accuracy but showed limitations in prospective real-time applications. This study provided insights to prepare for future iterations that will integrate near-IR spectroscopy to detect cerebral oximetry, and quantum dot light-emitting diodes to activate light-based treatment (photobiomodulation) from within a wearable head dressing. The findings underscore the potential of this platform to bridge critical gaps in acute TBI care through early detection and future therapeutic intervention. Further development is needed to address environmental challenges, improve accuracy across diverse populations, and refine the device for real-time clinical use. This innovative approach has the potential to revolutionize TBI care by bridging current gaps in diagnostic and therapeutic management.
