Outcomes With Postrecurrence Systemic Therapy Following Adjuvant Checkpoint Inhibitor Treatment for Resected Melanoma in CheckMate 238.

Purpose: In phase III CheckMate 238, adjuvant nivolumab significantly improved recurrence-free survival compared with ipilimumab in patients with resected stage IIIB-C/IV melanoma without a significant difference in overall survival (OS). Here, we investigate progression-free survival (PFS) and OS after postrecurrence systemic therapy.

Patients And Methods: Patients 15 years or older with resected stage IIIB-C/IV melanoma were stratified by stage and tumor PD-L1 status and randomly assigned to receive nivolumab 3 mg/kg every 2 weeks, or ipilimumab 10 mg/kg every 3 weeks for four doses and then every 12 weeks for 1 year or until disease recurrence, unacceptable toxicity, or withdrawal of consent.

Plain language summary of the CheckMate 76K study results: nivolumab given after stage 2B/2C melanoma is removed by surgery.

What Is This Summary About?: In this article, we summarize results from the ongoing phase 3 CheckMate 76K clinical study published online in in October 2023. The study goal was to learn whether nivolumab works as an adjuvant therapy (that is, helps to keep cancer from coming back when it is given after surgery) for stage 2 melanoma (skin cancer) that has not spread to other parts of the body. Nivolumab is an immunotherapy that activates a person's immune system so it can destroy cancer cells.

Adjuvant nivolumab in resected stage IIB/C melanoma: primary results from the randomized, phase 3 CheckMate 76K trial.

Patients with resected stage IIB/C melanoma have high recurrence risk, similar to those with resected stage IIIA/B disease. The phase 3, double-blind CheckMate 76K trial assessed 790 patients with resected stage IIB/C melanoma randomized 2:1 (stratified by tumor category) to nivolumab 480 mg or placebo every 4 weeks for 12 months. The primary endpoint was investigator-assessed recurrence-free survival (RFS).

BRCA mutation carriers suffering from ovarian cancer as a model for treatment decision in higher lines - Place for platinum reinduction.

Context: Ovarian carcinoma is a malignancy with the highest mortality among gynecological cancers. Mutations in BRCA1/2 genes are believed to be a favorable prognostic factor and that, in general, the biological behavior of ovarian cancer in BRCA-positive individuals differs from others. However, some clinically relevant issues (i.

Prevalence of myocardial injury in patients after acute ischaemic stroke according to standard criteria.

This study examined the prevalence of acute and chronic myocardial injury according to standard criteria in patients after acute ischaemic stroke (AIS) and its relation to stroke severity and short-term prognosis. Between August 2020 and August 2022, 217 consecutive patients with AIS were enrolled. Plasma levels of high-sensitive cardiac troponin I (hs-cTnI) were measured in blood samples obtained at the time of admission and 24 and 48 h later.

A Telemedicine System Intervention for Patients With Type 1 Diabetes: Pilot Feasibility Crossover Intervention Study.

Background: Today's diabetes-oriented telemedicine systems can gather and analyze many parameters like blood glucose levels, carbohydrate intake, insulin doses, and physical activity levels (steps). Information collected can be presented to patients in a variety of graphical outputs. Despite the availability of several technical means, a large percentage of patients do not reach the goals established in their diabetes treatment.

Adjuvant Nivolumab versus Ipilimumab in Resected Stage III/IV Melanoma: 5-Year Efficacy and Biomarker Results from CheckMate 238.

Purpose: In the phase III CheckMate 238 study, adjuvant nivolumab significantly improved recurrence-free survival (RFS) and distant metastasis-free survival versus ipilimumab in patients with resected stage IIIB-C or stage IV melanoma, with benefit sustained at 4 years. We report updated 5-year efficacy and biomarker findings.

Patients And Methods: Patients with resected stage IIIB-C/IV melanoma were stratified by stage and baseline programmed death cell ligand 1 (PD-L1) expression and received nivolumab 3 mg/kg every 2 weeks or ipilimumab 10 mg/kg every 3 weeks for four doses and then every 12 weeks, both intravenously for 1 year until disease recurrence, unacceptable toxicity, or withdrawal of consent.

Segmental Versus Partial Portomesenteric Resection in Pancreatectomy for Pancreatic Cancer.

Introduction: Portomesenteric vein resections are a well-established part of pancreatectomies for advanced tumors that invade the portomesenteric axis. There are two main types of portomesenteric resections: partial resections, where only part of the venous wall is removed and segmental resection, where the full circumference of the wall is removed. The aim of this study is to compare short-term and long-term outcomes between these two techniques.

Adjuvant nivolumab versus ipilimumab (CheckMate 238 trial): Reassessment of 4-year efficacy outcomes in patients with stage III melanoma per AJCC-8 staging criteria.

Purpose: Nivolumab was approved as adjuvant therapy for melanoma based on data from CheckMate 238, which enrolled patients per American Joint Committee on Cancer version 7 (AJCC-7) criteria. Here, we analyse long-term outcomes per AJCC-8 staging criteria compared with AJCC-7 results to inform clinical decisions for patients diagnosed per AJCC-8.

Patients And Methods: In a double-blind, phase 3 trial (NCT02388906), patients aged ≥15 years with resected, histologically confirmed AJCC-7 stage IIIB, IIIC, or IV melanoma were randomised to receive nivolumab 3 mg/kg every 2 weeks or ipilimumab 10 mg/kg every 3 weeks for 4 doses and then every 12 weeks, both intravenously ≤1 year.

Protocol for faecal microbiota transplantation in irritable bowel syndrome: the MISCEAT study - a randomised, double-blind cross-over study using mixed microbiota from healthy donors.

Introduction: Several studies have demonstrated dysbiosis in irritable bowel syndrome (IBS). Therefore, faecal microbiota transplantation, whose effect and safety have been proven in infections, may hold promise in other conditions, including IBS. Our study will examine the effectiveness of stool transfer with artificially increased microbial diversity in IBS treatment.

SARS-CoV-2 vaccination in the context of original antigenic sin.

Immunological memory is the ability of the adaptive immune system to ensure a persistent protective effect after immunization. However, it can also be a limitation to building a sufficient level of protective antibodies specific to new mutations of the virus. It is imperative to bear this phenomenon (called "original antigenic sin") in mind and make every effort to overcome its inherent pitfalls when updating current and designing new vaccines.

Background: Previously, findings from CheckMate 238, a double-blind, phase 3 adjuvant trial in patients with resected stage IIIB-C or stage IV melanoma, showed significant improvements in recurrence-free survival and distant metastasis-free survival with nivolumab versus ipilimumab. This report provides updated 4-year efficacy, initial overall survival, and late-emergent safety results.

Methods: This multicentre, double-blind, randomised, controlled, phase 3 trial was done in 130 academic centres, community hospitals, and cancer centres across 25 countries.

Botulinum Toxin for Chronic Lateral Epicondylitis (LE).

Lateral epicondylitis is a common disease in orthopaedic practice. Although the majority of cases do not become chronic, patients who do not respond to the initial treatment may suffer from pain in the long term and effective treatment is challenging. The off-label use of botulinum toxin is one of the common potential indications for the substance in orthopaedics and traumatology.

Background: The SafeTy Events in VIsmodEgib study (STEVIE, ClinicalTrials.gov, NCT01367665), assessed safety and efficacy of vismodegib-a first-in-class Hedgehog pathway inhibitor demonstrating clinical benefit in advanced basal cell carcinoma (BCC)-in a patient population representative of clinical practice. Primary analysis data are presented.

New and current preventive treatment options in actinic keratosis.

Actinic keratosis (AK) is a characteristic skin lesion on skin areas of subjects with mainly phototype I and phototype II, or with specific genetic factors and who are exposed to prolonged ultraviolet radiation. AK may be considered a precursor of in situ squamous cell carcinoma (SCC), a type of non-melanoma skin cancer (NMSC). However, it is still not possible to predict which AK lesions will develop into SCC.

The exercise-regulated myokine chitinase-3-like protein 1 stimulates human myocyte proliferation.

Aim: Chitinase-3-like protein 1 (CHI3L1) is involved in tissue remodelling and inflammatory processes. Plasma levels are elevated in patients with insulin resistance and T2DM. We recently showed that CHI3L1 and its receptor protease-activated receptor 2 (PAR-2) are expressed in skeletal muscle.

Epinephrine-stimulated glycogen breakdown activates glycogen synthase and increases insulin-stimulated glucose uptake in epitrochlearis muscles.

Epinephrine increases glycogen synthase (GS) phosphorylation and decreases GS activity but also stimulates glycogen breakdown, and low glycogen content normally activates GS. To test the hypothesis that glycogen content directly regulates GS phosphorylation, glycogen breakdown was stimulated in condition with decreased GS activation. Saline or epinephrine (0.
