Role of radiomics as a predictor of disease recurrence in ovarian cancer: a systematic review.

Ovarian cancer is associated with high cancer-related mortality rate attributed to late-stage diagnosis, limited treatment options, and frequent disease recurrence. As a result, careful patient selection is important especially in setting of radical surgery. Radiomics is an emerging field in medical imaging, which may help provide vital prognostic evaluation and help patient selection for radical treatment strategies.

Oral medicine considerations for the older patient.

With the proportion of the world population aged over 60 years expected to nearly double to 22% by 2050, health care professionals are faced with the challenge of ensuring they are ready to address this demographic shift. As people age, they are more likely to develop comorbidities which have implications for their oral health. The effects of polypharmacy used to address these underlying health problems can also influence the oral health of older-aged patients.

Background: There is increasing evidence of immune dysregulation and neuroinflammation occurring in schizophrenia. The aim of this study is to combine studies on routine CSF parameters, as well as cytokines and inflammatory proteins, in individuals with schizophrenia spectrum disorders.

Methods: CSF parameters were summated and inverse variance meta-analyses using a random effects model were performed comparing mean difference or odds ratios.

Barriers and enablers to achieving clinical procedure competency-based outcomes in a national paediatric training/residency program-a multi-centered qualitative study.

Background: In 2018, the Royal College of Physicians of Ireland revised its paediatric training program to a competency-based medical education (CBME) training/residency curriculum. This included a requirement to achieve competence in a number of core procedural skills to progress within the program. Internationally, simulation-based medical education (SBME) is gaining interest as an effective teaching pedagogy for training procedural skill competency.

Drug-Drug Interaction Studies of Esmethadone (REL-1017) Involving CYP3A4- and CYP2D6-Mediated Metabolism.

Background And Objective: Esmethadone (dextromethadone; d-methadone; S-methadone (+)-methadone; REL-1017) is the opioid inactive dextro-isomer of racemic methadone. Esmethadone is a low potency N-methyl-D-aspartate (NMDA) receptor channel blocker with higher affinity for GluN2D subtypes. Esmethadone showed robust, rapid, and sustained antidepressant effects in patients with major depressive disorder (MDD) with inadequate response to ongoing serotonergic antidepressant treatment.

Unusual presentation of pyostomatitis vegetans and its management.

A man in his early 50s was referred to the oral medicine clinic regarding a 6-month history of ulceration affecting the palate and gingivae. Intra-oral examination revealed multiple friable pustules on a background of erythema affecting the gingival sulci and 'snail-track' like ulceration affecting the palate. Histopathological analysis of the gingivae revealed features in keeping with a diagnosis of pyostomatitis vegetans (PV).

Addressing child and adolescent obesity management in Ireland: identifying facilitators and barriers in clinical practice.

Background: Ireland's Model of Care for the Management of Overweight and Obesity outlines a plan for treating adolescent and child obesity (CO). However, engagement with key stakeholders is required to support its implementation and improve health services.

Aim: This study aims to map the perceived barriers and facilitators related to CO management across healthcare settings, professional disciplines, and regions in the Republic of Ireland (ROI).

The novel uncompetitive NMDA receptor antagonist esmethadone (REL-1017) has no meaningful abuse potential in recreational drug users.

Esmethadone (REL-1017) is the opioid-inactive dextro-isomer of methadone and a low-affinity, low-potency uncompetitive NMDA receptor antagonist. In a Phase 2, randomized, double-blind, placebo-controlled trial, esmethadone showed rapid, robust, and sustained antidepressant effects. Two studies were conducted to evaluate the abuse potential of esmethadone.

Esmethadone-HCl (REL-1017): a promising rapid antidepressant.

This review article presents select recent studies that form the basis for the development of esmethadone into a potential new drug. Esmethadone is a promising member of the pharmacological class of uncompetitive N-methyl-D-aspartate receptor (NMDAR) antagonists that have shown efficacy for major depressive disorder (MDD) and other diseases and disorders, such as Alzheimer's dementia and pseudobulbar affect. The other drugs in the novel class of NMDAR antagonists with therapeutic uses that are discussed for comparative purposes in this review are esketamine, ketamine, dextromethorphan, and memantine.

Guidelines for treating child and adolescent obesity: A systematic review.

Obesity is a chronic disease that compromises the physical and mental health of an increasing proportion of children globally. In high-income countries, prevalence of paediatric obesity is increasing faster in those from marginalised populations such as low-income households, suggesting the disease as one that is largely systemic. Appropriate treatment should be prioritised in these settings to prevent the development of complications and co-morbidities and manage those that already exist.
