Actinomycetota From Macroalgae as Rich Source for Natural Products Discovery Revealed Through Culture-Dependent and -Independent Approaches.

Actinomycetota are unrivalled producers of bioactive natural products, with strains living in association with macroalgae representing a prolific-yet largely unexplored-source of specialised chemicals. In this work, we have investigated the bioactive potential of Actinomycetota from macroalgae through culture-dependent and -independent approaches. A bioprospecting pipeline was applied to a collection of 380 actinobacterial strains, recovered from two macroalgae species collected in the Portuguese northern shore-Codium tomentosum and Chondrus crispus-in order to explore their ability to produce antibacterial, antifungal, anticancer and lipid-reducing compounds.

Exploring the genetic contribution in obesity: An overview of dopaminergic system genes.

Obesity is a widespread global health concern that affects a significant portion of the population and is associated with reduced quality of life, morbidity, and mortality. It is considered a pandemic, with its prevalence constantly rising in Western countries. As a result, numerous studies have focused on understanding the elements that contribute to obesity.

Spinal Cord Stimulator Complication Rates: A Single-Institution, 22-Year Study (1999-2021).

Background: Since the initial introduction in 1967 of spinal cord stimulation (SCS) in the field of neuromodulation, SCS has been utilized to treat a multitude of chronic pain disorders refractory to both conservative and surgical management. Although efficacious when indicated, SCS has associated risks.

Objectives: The goals of this study are to explore the trend of rates of SCS complications in 2 approximately equally sized cohorts (1999-2015 and 2016-2021) within a single institution over a 22-year period.

Analysis of functionality, pain and quality of life after surgically treated ankle fractures in active and inactive individuals.

Although the ankle is often involved in low energy trauma, high-energy trauma may occur, being this considered more serious and more common of affecting young and active men. The purpose of the present study was to evaluate and compare the functionality, pain and quality of life of active and inactive adult individuals whose ankle fracture was surgically treated. Seventy-six patients split into two groups (active, n = 58 X inactive, n = 18), of the men (active, n = 38; inactive, n = 9) and women (active, n = 20; inactive, n = 9) gender participated in this prospective study.

Determination of Inhibitory Effect of PKM2 Enzyme and Antitumoral Activity of Novel Coumarin-Naphthoquinone Hybrids.

Background: Oral squamous cell carcinoma (OSCC) represents the primary form of oral cancer, posing a significant global health threat. The existing chemotherapy options are accompanied by notable side effects impacting patient treatment adherence. Consequently, the exploration and development of novel substances with enhanced anticancer effects and fewer side effects have become pivotal in the realms of biological and chemical science.

Artificial Intelligence and Virtual Reality in Headache Disorder Diagnosis, Classification, and Management.

Purpose Of Review: This review provides an overview of the current and future role of artificial intelligence (AI) and virtual reality (VR) in addressing the complexities inherent to the diagnosis, classification, and management of headache disorders.

Recent Findings: Through machine learning and natural language processing approaches, AI offers unprecedented opportunities to identify patterns within complex and voluminous datasets, including brain imaging data. This technology has demonstrated promise in optimizing diagnostic approaches to headache disorders and automating their classification, an attribute particularly beneficial for non-specialist providers.

Silica-Poly(Vinyl Alcohol) Composite Aerogel: A Promising Electrolyte for Solid-State Sodium Batteries.

The transition from fossil fuels is in part limited by our inability to store energy at different scales. Batteries are therefore in high demand, and we need them to store more energy, be more reliable, durable and have less social and environmental impact. Silica-poly(vinyl alcohol) (PVA) composite aerogels doped with sodium perchlorate were synthesized as novel electrolytes for potential application in solid-state sodium batteries.

Intrathecal Morphine for Cardiac Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Cardiac surgeries often result in significant postoperative pain, leading to considerable use of opioids for pain management. However, excessive opioid use can lead to undesirable side effects and chronic opioid use. This systematic review and meta-analysis aimed to evaluate whether preoperative intrathecal morphine could reduce postoperative opioid consumption in patients undergoing cardiac surgery requiring sternotomy.

CSCE-cadherin immunohistochemistry panel predicts poor prognosis in oral squamous cell carcinoma.

Identifying marker combinations for robust prognostic validation in primary tumour compartments remains challenging. We aimed to assess the prognostic significance of CSC markers (ALDH1, CD44, p75NTR, BMI-1) and E-cadherin biomarkers in OSCC. We analysed 94 primary OSCC and 67 metastatic lymph node samples, including central and invasive tumour fronts (ITF), along with clinicopathological data.

Literature Review: Mechanism, Indications, and Clinical Efficacy of Peripheral Nerve Stimulators in Lower Extremity Pain.

Purpose Of Review: Lower extremity pain is deemed by Center for Disease Control and Prevention (CDC) to be a significant source of chronic pain in adults. If not appropriately managed, patients are subjected to risks of prolonged musculoskeletal dysfunction, disruption to quality of life, and elevated healthcare expenditures. Peripheral nerve stimulation (PNS) has shown great potential in recent years demonstrating efficacy in multiple diagnoses ranging from acute post-surgical pain to complex regional pain syndrome (CRPS).

Scoping Review: The Role of Psychedelics in the Management of Chronic Pain.

Introduction: Amid a lack of effective chronic pain treatments, psychedelics have gained attention as a potential solution, although their Schedule 1 classification poses challenges. Psychedelics, such as lysergic acid diethylamide (LSD) and psilocybin, have gained popularity as alternatives and adjuncts for chronic pain treatment. Studies suggest that they may modulate pain processing through agonism primarily at the serotonin receptor, 5-HT.

Stroke frequency, associated factors, and clinical features in primary systemic vasculitis: a multicentric observational study.

Methods: This is a multicenter observational retrospective international study (16 countries, 63 sites) that included patients with cervical artery dissection without major trauma.

Deep Learning-Based Extraction of Biomarkers for the Prediction of the Functional Outcome of Ischemic Stroke Patients.

Accurately predicting functional outcomes in stroke patients remains challenging yet clinically relevant. While brain CTs provide prognostic information, their practical value for outcome prediction is unclear. We analyzed a multi-center cohort of 743 ischemic stroke patients (<72 h onset), including their admission brain NCCT and CTA scans as well as their clinical data.

Stroke and Recent Myocardial Infarction, Reduced Left Ventricular Ejection Fraction, Left Ventricular Thrombus, and Wall Motion Abnormalities.

Purpose Of Review: To review the evidence regarding stroke and recent myocardial infarction (MI), reduced left ventricular ejection fraction, left ventricular thrombus (LVT), and wall motion abnormalities (WMA).

Recent Findings: The risk of ischemic stroke associated with acute MI has been greatly reduced with reperfusion treatments that improved myocardium salvage. Acute ischemic stroke is an uncommon complication of diagnostic coronary angiography and percutaneous coronary intervention.
