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.

OBJECTIVE The Centers for Medicare & Medicaid Services (CMS) requires a low C-peptide level for insulin pump coverage unless the individual is β-cell autoantibody positive, which precludes coverage of automated insulin delivery (AID) systems for many people with type 2 diabetes. RESEARCH DESIGN AND METHODS In the Randomized Trial Evaluating the Efficacy and Safety of Control-IQ+ Technology in Adults With Type 2 Diabetes Using Basal-Bolus Insulin Therapy study evaluating the t:slim X2 insulin pump with Control-IQ+ technology, adults with insulin-treated type 2 diabetes were categorized into high C-peptide (n = 195) and low C-peptide (n = 59) groups based on CMS criteria. RESULTS In the AID group, mean HbA1c decreased from baseline by 0.8%, which was significantly greater than in the control group with both high (P < 0.001) and low (P = 0.02) C-peptide levels. Results were similar in participants ≥65 years old. CONCLUSIONS The benefit of AID is present with high and low C-peptide levels. Thus, requiring a low C-peptide level as a prerequisite for AID therapy is not warranted.

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.

Abstract May-Thurner physiology (MTP) can lead to various congestion syndromes due to compression of the left common iliac vein (LCIV) by the right common iliac artery (RCIA). This compression may result in venous reflux through the lumbar vein, leading to congestion of the spinal epidural venous plexus (EVP), which could contribute to refractory headaches. This case report details the clinical course of a patient with severe refractory new daily persistent headache associated with MTP who underwent ascending lumbar vein (ALV) embolization. The patient is a 59-year-old female with a 3-year history of daily persistent headache which failed multiple migraine prevention therapies and minimally invasive procedures. Imaging studies revealed significant LCIV compression by the RCIA, retrograde ALV flow, and EVP congestion. The patient underwent ALV embolization, resulting in significant symptomatic relief. At the 22-month follow-up, headache severity reduced by 80%, with the patient no longer requiring routine headache medications. Additionally, treatment of associated pelvic congestion syndrome through gonadal vein embolization resolved longstanding associated pelvic pain and pressure. This case highlights the role of venous congestion in refractory headache syndromes and underscores the potential of targeted venous interventions, such as embolization, in their management. The findings expand on emerging evidence linking venous compression syndromes to headache pathophysiology and support exploring interventional strategies as viable treatment options for selected patients. Further research is needed to validate these findings and establish evidence-based guidelines for clinical practice.

Abstract Uterine fibroids (leiomyomas) and adenomyosis are among the most common benign gynecological conditions affecting women of reproductive age. These disorders are frequently associated with abnormal uterine bleeding, pelvic pain, pressure symptoms on adjacent pelvic organs, and potential infertility. The incidence of fibroids increases as women enter their third and fourth decades of life. In parallel, recent trends in delayed childbearing have further emphasized the need for fertility‐preserving treatment options. Notably, fibroids have a higher prevalence in African‐American women, highlighting a significant disparity in health needs compared to white women. Historically, hysterectomy and myomectomy were considered definitive treatments. However, these procedures carry inherent surgical risks, longer recovery periods, and, in the case of hysterectomy, a complete loss of reproductive potential. Consequently, there is increasing demand for uterus‐sparing, minimally invasive alternatives that provide effective symptom control with lower morbidity and preservation of fertility. Among the evolving treatment options, three image‐guided, minimally invasive therapies have gained particular attention: Uterine Artery Embolization (UAE), Radiofrequency Ablation (RFA), and High‐Intensity Focused Ultrasound (HIFU). Uterine Artery Embolization (UAE), also known as uterine fibroid embolization (UFE), is a well‐established endovascular procedure in which embolic agents are introduced via catheterization of the uterine arteries, inducing ischemia and infarction of fibroids. Performed under conscious sedation or regional anesthesia, UAE has demonstrated significant reductions in fibroid volume and symptom relief in over 80% of appropriately selected patients. All image‐guided techniques are especially beneficial for women who desire uterine preservation, have contraindications to surgery, or wish to avoid major operative interventions. In comparison with UAE, Radiofrequency Ablation (RFA) uses targeted thermal energy to induce coagulative necrosis within fibroid tissue. This approach can be delivered via laparoscopic, transcervical, or transvaginal routes, depending on the platform. The Sonata® System integrates intrauterine ultrasound guidance with energy delivery, enabling precise fibroid targeting with minimal myometrial damage. RFA is associated with shorter recovery and less intraoperative blood loss, though it is more suitable for smaller or fewer fibroids and may be less ideal for extensive disease. Together, these advancements reflect a paradigm shift in fibroid management—driven by demographic trends, racial disparities, patient preferences, and technological innovations—toward evidence‐based, uterus‐preserving therapies tailored to individual patient needs. This article discusses details of each technique including the procedure, benefits and complications and also the impact on particular situations such as pregnancy. Some key points common to each technique are also mentioned.

ABSTRACT Human papillomavirus (HPV) is comprised of >200 genotypes and has an ~8 kb, circular, double-stranded DNA genome. Transmission of HPV occurs through skin-to-skin contact and infection of squamous epithelial cells of cutaneous and mucosal surfaces. HPV genotypes are categorized as low- or high-risk (hrHPV) based on oncogenic potential. There are approximately 14 types of hrHPV that can cause several types of cancer, including HPV-associated oropharyngeal squamous cell carcinoma (HPV(+)OPSCC). Detection of HPV(+)OPSCC is traditionally accomplished using p16 immunohistochemistry (IHC) and HPV-specific testing, either DNA or RNA in situ hybridization (ISH) staining or DNA-based PCR of suspected tumor biopsy tissue. More recently, platelet-poor plasma (PPP) samples from patients with HPV(+)OPSCC have proven useful for detection and quantitation of fragments of HPV circulating tumor DNA (ctDNA). ctDNA has been shown to be useful in determining treatment response and monitoring for disease recurrence. In this study, a novel droplet digital PCR assay (ddPCR) was developed and validated for the detection and quantitation of ctDNA from 5 hrHPV genotypes in PPP. Analytical sensitivity ranged from 7.71 to 19.45 fragments of HPV ctDNA per milliliter of PPP across five hrHPV genotypes. In patients with confirmed primary or recurrent HPV(+)OPSCC or HPV(-)OPSCC, testing of corresponding PPP samples ( n = 32) by ddPCR demonstrated 90.63% (29/32) overall agreement with p16/HPV-ISH biopsy results. Compared with reference ddPCR assays performed at outside laboratories, our ddPCR assay yielded 90% (9/10) overall agreement. This assay may provide clinicians with a tool for monitoring HPV ctDNA prior to, during, and after treatment of an HPV-associated cancer. IMPORTANCE At least 14 genotypes of human papillomavirus (HPV) have been identified to have high oncogenic potential. While molecular diagnostic testing for HPV is widely available for liquid cytologic cervical samples, testing is limited for other sample types, including liquid biopsy samples, such as platelet-poor plasma (PPP). With the rising incidence of HPV-associated oropharyngeal squamous cell carcinoma (HPV(+)OPSCC), laboratory testing is an essential part of patient diagnosis, management, and surveillance. Here, we summarize the development and analytical performance validation of a multiplexed, droplet digital PCR (ddPCR) assay for the detection and quantitation of HPV circulating tumor DNA (ctDNA) in PPP. This assay may provide clinicians with a tool to address minimal residual disease for patients with an HPV-associated cancer.

Abstract Background and Aims In the VICTOR trial (NCT05093933), vericiguat was neutral for the primary composite endpoint of cardiovascular death or hospitalization for heart failure (HF). VICTOR was powered to independently assess cardiovascular death. This study reports detailed analysis on the effects of vericiguat on mortality. Methods VICTOR, a double-blind, placebo-controlled, randomized trial, enrolled 6105 ambulatory patients with HF and reduced ejection fraction (HFrEF) without recent worsening and randomized them to vericiguat or placebo. The main outcome for this analysis was the pre-specified secondary endpoint of cardiovascular death. All-cause death, sudden cardiac death, and death related to HF were also assessed. Results Over a median of 19.7 months (inter-quartile range 14.6–25.4), cardiovascular deaths occurred in 292 patients (5.7 deaths per 100 patient-years) and 346 patients (6.8 deaths per 100 patient-years) in the vericiguat and placebo groups, respectively (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.71–0.97; P = .020). Risk of death from any cause was lower with vericiguat vs placebo (377 [7.3 deaths per 100 patient-years] vs 440 [8.6 deaths per 100 patient-years]; HR 0.84, 95% CI 0.74–0.97; P = .015). Sudden cardiac death and HF-related deaths were lower with vericiguat vs placebo (1.6 vs 2.2 events per 100 patient-years; HR 0.75, 95% CI 0.56–0.99; P = .042 and 1.7 vs 2.4 events per 100 patient-years; HR 0.71, 95% CI 0.54–0.94; P = .016, respectively). Lower mortality rates were consistent across subgroups including baseline therapy. Consistent cardiovascular and all-cause mortality benefit was seen across baseline N-terminal pro-B-type natriuretic peptide levels. Conclusions In ambulatory well-treated participants with HFrEF, vericiguat was associated with clinically meaningful reductions in the key secondary outcome of cardiovascular death, as well as all-cause mortality.

Background: Transfusion has a persistent low risk of transfusion-transmitted infection and transfusion-associated graft- versus -host disease that may be addressed using pathogen reduction. The Red Cell Pathogen Inactivation (ReCePI) trial tested whether amustaline/glutathione pathogen-reduced red cells are noninferior to conventional transfusions for support of acute surgical blood loss. Methods: A phase 3, double-blinded, noninferiority trial randomized cardiac or thoracic–aorta surgery patients with increased risk of red cell transfusion to receive pathogen-reduced or conventional red cells during and for 7 days postsurgery. The primary endpoint was the proportion of patients with acute kidney injury (AKI), which is defined as an increase from baseline of greater than or equal to 0.3 mg/dl serum creatinine within 48 h of surgery. Noninferiority was claimed if the upper bound 95% CI of the treatment difference was less than half (50%) of the observed conventional arm incidence. Adverse events and treatment-emergent red cell antibodies were assessed for 28 and 75 days, respectively. Results: A total of 581 subjects were randomized, and 321 (55%) were transfused with study red cells. Transfused subjects in both arms had similar baseline demographics, medical histories, hemoglobin levels, and surgical procedures. Hemoglobin day 3 nadir levels (8.6 g/dl [7.8 to 9.2] in the pathogen-reduced arm; 8.4 g/dl [7.8 to 9.3] in the conventional arm; P = 0.52) were comparable. Incidence of AKI by 48 h was 46 of 157 (29.3%) in the pathogen-reduced arm and 45 of 161 (28.0%) in the conventional arm (treatment difference, 0.7%; 95% CI, −8.9 to 10.4%; noninferiority margin, 14.0%; P = 0.001 for noninferiority). AKI within 7 days by Kidney Disease Improving Global Outcomes staging criteria was not different (59 of 159 [37.1%] in the pathogen-reduced arm; 55 of 162 [34.0%] in the conventional arm; P = 0.53), but stage III was more common in the pathogen-reduced arm (pathogen-reduced arm, 15 of 159 [9.4%]; conventional arm, 7 of 162 [4.3%]; P = 0.075). Of 159 pathogen-reduced red cell recipients, 5 (3.1%) developed specific, low-titer antibodies without evidence of hemolysis. Conclusions: The incidence of AKI in recipients of pathogen-reduced red cells was noninferior to conventional red cell transfusion. Treatment-emergent antibodies were uncommon and not clinically significant.
