Purpose: To evaluate organ-specific response to [Lu]DOTATATE Peptide Receptor Radionuclide Therapy (PRRT) in patients with small intestine neuroendocrine tumor (SiNET) through [Ga]DOTATOC PET/CT, and to analyze tumor uptake and functional volume variations at different metastatic sites in relation to disease progression during clinical follow-up after treatment.

Methods: A retrospective analysis was conducted on 33 metastatic patients. PET/CT were performed pre-treatment (PET0), mid-treatment after two PRRT cycles (PET2), and post-treatment (PET4).

Early and Long-Term Outcomes of Patients With Acute Coronary Syndrome Who Underwent Percutaneous Coronary Intervention to the Left Main Coronary Artery.

Patients who underwent percutaneous coronary intervention (PCI) to the left main (LM) coronary artery in the setting of acute coronary syndrome (ACS) were not adequately studied in the era of modern PCI. We investigated early and long-term outcomes of these patients, especially those with a true LM bifurcation stenosis. The Left Main Intervention in Acute Coronary Syndrome (LIMACS) is a multicenter registry that enrolled patients who underwent PCI to unprotected LM disease in the setting of ACS using a drug-eluting stent.

Early palliative care and overall survival in patients with metastatic upper gastrointestinal cancers (EPIC): a multicentre, open-label, randomised controlled phase 3 trial.

Background: Early palliative care (EPC) leads to an improvement in quality of life and an unexpected survival benefit compared with oncological care for patients with metastatic lung cancer. The Early Palliative Integrated Care (EPIC) is aimed at examining whether EPC can improve overall survival in patients with metastatic upper gastrointestinal cancer.

Methods: We performed a multicentre, open-label, randomised phase-3 trial.

Acceptability, tolerability and safety of the BRIGhTMIND trial: Connectivity-guided intermittent theta-burst stimulation versus F3- repetitive transcranial magnetic stimulation for treatment-resistant depression.

Background: The BRIGhTMIND study was a double-blind RCT comparing repetitive transcranial magnetic stimulation at a standard simulation site (the "F3" location given by the International 10-20 system, F3-rTMS) versus connectivity-guided intermittent theta burst stimulation (cgiTBS) for treatment-resistant depression. This present study reports the acceptability, safety, and tolerability of F3-rTMS versus cgiTBS.

Methods: The present study used quantitative and qualitative methods.

Olaparib as maintenance therapy in non resectable pancreatic adenocarcinoma associated with homologous recombination deficiency profile: A French retrospective multicentric AGEO real-world study.

Background: Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis. The POLO trial showed that olaparib (PARP inhibitor) improved progression-free survival (PFS) but not overall survival (OS), when used as maintenance therapy after ≥ 16 weeks of disease control with first-line platinum-based chemotherapy in patients with germline (g) BRCA 1 or 2 pathogenic variants (PV) metastatic PDAC. However, real-world data on the effectiveness of olaparib are missing.

Rationale and Design of the COPERNIC Trial: A Study of On-treatment ctDNA Changes in Chemo-refractory Colorectal Cancer Patients.

Background: Evidence suggests that ctDNA may be a reliable biomarker to monitor metastatic colorectal cancer (CRC) evolution. Nevertheless, evidence on the potential of liquid biopsy in this setting is still low quality, mostly consisting of retrospective studies.

Methods: COPERNIC is an international, multicenter clinical trial.

Mass spectrometry identifies tau C-terminal phosphorylation cluster during neuronal hyperexcitation.

Tau is a microtubule-associated protein implicated in Alzheimer's disease (AD) and other neurodegenerative disorders termed tauopathies. Pathological, aggregated forms of tau form neurofibrillary tangles (NFTs), impairing its ability to stabilize microtubules and promoting neurotoxicity. Indeed, NFTs correlate with neuronal loss and cognitive impairment.

Dual Coronary Artery Thrombosis: An Unforeseen Angiographic Encounter.

Acute myocardial infarction (AMI) frequently involves single-vessel coronary artery disease, but simultaneous thrombosis in multiple coronary arteries is a rare and challenging clinical scenario. We report the case of a 42-year-old Southeast Asian male with a six-month history of hypertension controlled by a single antihypertensive agent, presenting to the emergency department with central chest pain radiating to the back. The initial electrocardiography (ECG) showed ST elevation in the inferior leads.

Development and validation of AI-assisted transcriptomic signatures to personalize adjuvant chemotherapy in patients with pancreatic ductal adenocarcinoma.

Background: After surgical resection of pancreatic ductal adenocarcinoma (PDAC), patients are predominantly treated with adjuvant chemotherapy, commonly consisting of gemcitabine (GEM)-based regimens or the modified FOLFIRINOX (mFFX) regimen. While mFFX regimen has been shown to be more effective than GEM-based regimens, it is also associated with higher toxicity. Current treatment decisions are based on patient performance status rather than on the molecular characteristics of the tumor.

Impact of papain on the treatment of raw diluted dromedary semen.

A variety of parameters, including liquefaction and semen viscosity, affect the sperm's ability to travel and reach the egg for fertilization and conception. Given that the details behind the viscosity of the semen in male camels have not yet been fully clarified, the purpose of this study was to ascertain how the addition of papain affected the viscosity of fresh diluted camel semen. The study examined semen samples derived from camels that had distinct viscosities.

Tricuspid valve and right-heart chamber remodelling in elderly subjects with secondary tricuspid regurgitation.

Background: The prevalence of secondary tricuspid regurgitation (TR) increases with ageing, but the exact mechanisms and the pattern of tricuspid valve (TV) remodelling are yet to be defined. This knowledge is needed to guide patient selection for the evolving therapeutic options. We sought to explore the prevalence and predictors of secondary TR in the elderly, as well as the associated pattern of right-heart chamber and TV remodelling.

Low concentrations of soybean lecithin nanoparticles had a positive impact on Holstein bulls' cryopreserved semen.

Spermatozoa can experience negative changes when subjected to freezing and thawing, including lowered motility, viability and acrosome response. Herein, the effects of different concentrations of soybean lecithin nanoparticles on cryopreserved Holstein bull semen were examined. Semen was collected, cryopreserved and utilized for sperm kinetic parameter analysis following dilution, equilibration and thawing with 0.

Acute Triple Coronary Artery Occlusion Leading to Cardiogenic Shock and Cardiac Arrest Emphasizing the Role of Mechanical Circulatory Support (Escalate before It's Too Late).

We report a case of cardiac arrest in a 38-year-old male with no past medical history who presented as a case of ST-segment elevation myocardial infarction, and coronary angiography showed triple coronary artery thrombosis complicated with cardiogenic shock (CS) that warrants starting on inotropic support and insertion of intra-aortic balloon pump. CS diagnosis with a high likelihood of deterioration was established based on hemodynamics assessment; hence, an early prompt decision for escalation of mechanical circulatory support to Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) was made, which helped to prevent the patient's further deterioration and organ damage. The patient had uneventful VA-ECMO decannulation and was transferred to the ward and discharged after 28 days in stable condition on oral medical therapy and was following up regularly in the cardiology clinic.

Ten-year Durability, Hemodynamic Performance, and Clinical Outcomes after Transcatheter Aortic Valve Implantation Using a Self-expanding Device.

Introduction: The expansion of transcatheter aortic valve implantation (TAVI) to low-risk and younger patients has increased the relevance of the long-term durability of transcatheter heart valves (THV). The present study aims to assess the 10-year durability, hemodynamic performance, and clinical outcomes after TAVI using the CoreValve system.

Methods: An analysis from a prospective registry with predefined clinical and echocardiographic follow-up included 302 patients who underwent TAVI with the CoreValve system between 2007 and 2015.

The study also aimed to determine which bacteria were most commonly implicated in the development of the disease.

Extrapulmonary tuberculosis presenting as hemorrhagic pleuro-pericardial effusions with pericardial mass.

Key Clinical Message: Tuberculosis (TB) pericarditis, while uncommon, should be considered in patients with pericardial masses and effusion. Timely recognition and treatment with anti-TB medications are crucial for a successful outcome.

Abstract: TB pericarditis presenting as a pericardial mass is an unusual and rare manifestation of this disease.

A multicenter study evaluating efficacy of immune checkpoint inhibitors in advanced non-colorectal digestive cancers with microsatellite instability.

Background: One randomized phase III trial comparing chemotherapy (CT) with immune checkpoint inhibitors (ICI) has demonstrated significant efficacy of ICI in deficient DNA mismatch repair system/microsatellite instability-high (dMMR/MSI-H) metastatic colorectal cancer. However, few studies have compared ICI with CT in other advanced dMMR/MSI-H digestive tumors.

Methods: In this multicenter study, we included patients with advanced dMMR/MSI-H non-colorectal digestive tumors treated with chemotherapy and/or ICIs.

Assessment of suitability for percutaneous mitral commissurotomy: a contemporary review of key anatomical criteria and predictive models.

The immediate result of percutaneous balloon mitral commissurotomy is largely determined by the anatomy of the mitral valve complex. Several scores and models have been developed to assess anatomical suitability for percutaneous balloon mitral commissurotomy. Although none has an optimal predictive power, these models look at the valvular apparatus from different perspectives bearing the potential for a complementary role.

Connectivity-guided intermittent theta burst versus repetitive transcranial magnetic stimulation for treatment-resistant depression: a randomized controlled trial.

Disruption in reciprocal connectivity between the right anterior insula and the left dorsolateral prefrontal cortex is associated with depression and may be a target for neuromodulation. In a five-center, parallel, double-blind, randomized controlled trial we personalized resting-state functional magnetic resonance imaging neuronavigated connectivity-guided intermittent theta burst stimulation (cgiTBS) at a site based on effective connectivity from the right anterior insula to the left dorsolateral prefrontal cortex. We tested its efficacy in reducing the primary outcome depression symptoms measured by the GRID Hamilton Depression Rating Scale 17-item over 8, 16 and 26 weeks, compared with structural magnetic resonance imaging (MRI) neuronavigated repetitive transcranial magnetic stimulation (rTMS) delivered at the standard stimulation site (F3) in patients with 'treatment-resistant depression'.
