[Psychedelics in psychiatry: an open debate].

The application of psychedelics in psychiatry and psychotherapy is increasingly the subject of scientific evaluation and discussion in national and international professional and general society, and, internationally, has already been partly applied in the clinical setting. The manuscript provides a basic description of the state of the art regarding evidence and clinical issues; law, ethics and economics are addressed; therapeutic qualification of potential users and a potentially clinical embedding in psychiatry are discussed, taking into consideration current challenges. Thus, the discussion will cover the circumstances under which the application of psychedelics might have a potential to broaden the spectrum of treatments in certain psychiatric conditions, particularly in the context of chronicity and treatment resistance to current methods.

Cannabinoids and the heart-a psychiatrist's perspective.

The partial legalization of cannabis in Germany in 2024 will affect both medical and recreational use of cannabis. Tetrahydrocannabinol (THC), the main psychoactive component of the cannabis plant, influences heart rate and blood pressure through the endocannabinoid system. Acute and chronic use can pose cardiovascular risks.

The short-term postoperative pain and impact upon quality of life of pulpotomy and root canal treatment, in teeth with symptoms of irreversible pulpitis: A randomized controlled clinical trial.

Background: Few studies focus upon patient-reported outcomes in endodontics.

Aim: To determine whether full pulpotomy offers a less painful, improved health-related quality of life (HRQoL) compared with root canal treatment (RCT) in cases of irreversible pulpitis (IP) in the 7 days after the treatment.

Methodology: One hundred sixty-eight participants presenting with symptoms of IP were randomized to either pulpotomy (n = 86) or RCT (n = 82).

Tooth loss and depression in Chilean participants of the National Health Survey 2016-2017: Oral and social functions mediation analysis.

Background: Previous studies have indicated the association between poor oral health and depression in adults. This study evaluated oral and social functions contribution to the association between tooth loss and depressive symptoms in Chilean individuals.

Methods: We used data from the Chilean National Health Survey.

Assessment of Bacterial Load and Post-Endodontic Pain after One-Visit Root Canal Treatment Using Two Types of Endodontic Access Openings: A Randomized Controlled Clinical Trial.

The need for controlling bacteria and pain during root canal therapy is undeniable. This clinical trial aimed to assess whether there is a difference in colony-forming unit (CFU) reduction after instrumentation and post-endodontic pain after root canal treatment (RCT) using a traditional endodontic cavity (TEC) versus a conservative endodontic cavity (CEC). This clinical study was conducted on 89 patients designated for a single-visit RCT.

Sex Differences in Adult Incarceration After Pediatric Traumatic Brain Injury.

Pediatric traumatic brain injury (pTBI) is a major risk factor associated with adulthood incarceration. Most research into the link between pTBI and adulthood incarceration has focused on incarcerated males, who comprise the vast majority of incarcerated adults, particularly in industrialized nations. In this review, we sought to identify sex-related differences in the incidence and pathophysiology of pTBI and subsequent risk of adulthood incarceration.

Treatment success in cats with chronic enteropathy is associated with a decrease in fecal calprotectin concentrations.

Feline chronic enteropathies (FCE) are challenging to diagnose and monitor for progression and response to treatment. Fecal calprotectin might be a useful non-invasive marker to evaluate clinical endpoints of therapeutic monitoring in FCE. We evaluated fecal calprotectin concentrations in cats with FCE before and after initiation of treatment comprised of immunomodulation and/or dietary intervention.

A qualitative analysis of patient and caregiver experiences with myelomeningocele through online discussion boards.

Purpose: Patients and caregivers impacted by myelomeningocele (MMC) use online discussion board forums to create community and share information and concerns about this complex medical condition. We aim to identify the primary concerns expressed on these forums with the goal of understanding gaps in care that may merit investment of resources to improve care received by this population.

Methods: Anonymous posts from online MMC discussion boards were compiled using internet search engines.

Patient and caregiver perceptions of Chiari malformation: a qualitative analysis of online discussion boards.

Objective: Patients and their caregivers utilize online discussion board forums as a means to seek and exchange information about their or a loved one's condition. It is important for providers to be aware of such concerns and experiences. The goal of this study was to identify the primary concerns expressed on these discussion boards regarding Chiari malformation type I (CM) and to help guide clinicians in understanding patient challenges in the treatment of CM.

Neurofeedback for alcohol addiction: Changes in resting state network activity.

Alcohol dependence continues to be a major global burden despite significant research progress and treatment development. The aim of this study was to investigate whether neurofeedback training can alter resting state fMRI activity in brain regions that play a crucial role in addiction disorders in patients with alcohol dependence. For this purpose, a total of 52 patients were recruited for the present study, randomized, and divided into an active and a sham group.

MRI analysis of neurodevelopmental anatomy in myelomeningocele: prenatal vs postnatal repair.

Objective: Compared with postnatal repair, prenatal myelomeningocele (MMC) repair is associated with improved motor function and decreased need for cerebrospinal fluid (CSF) diversion. It is unknown how prenatal surgery alters neuroanatomical structures identifiable on magnetic resonance imaging (MRI). The purpose of this study was to use MRI to compare neurodevelopmental anatomy in patients undergoing fetal MMC repair compared with those undergoing postnatal repair.

Helmet Therapy for the Management of Deformational Plagiocephaly in Pediatric Patients with Shunted Hydrocephalus.

Objective: To evaluate the safety and efficacy of helmet therapy for deformational plagiocephaly in patients with shunted hydrocephalus.

Design: Retrospective chart review.

Setting: Institutional, tertiary-care hospital.

Postnatal meningeal CSF transport is primarily mediated by the arachnoid and pia maters and is not altered after intraventricular hemorrhage-posthemorrhagic hydrocephalus.

Background: CSF has long been accepted to circulate throughout the subarachnoid space, which lies between the arachnoid and pia maters of the meninges. How the CSF interacts with the cellular components of the developing postnatal meninges including the dura, arachnoid, and pia of both the meninges at the surface of the brain and the intracranial meninges, prior to its eventual efflux from the cranium and spine, is less understood. Here, we characterize small and large CSF solute distribution patterns along the intracranial and surface meninges in neonatal rodents and compare our findings to meningeal CSF solute distribution in a rodent model of intraventricular hemorrhage-posthemorrhagic hydrocephalus.

SH2 domain protein E and ABL signaling regulate blood vessel size.

Blood vessels in different vascular beds vary in size, which is essential for their function and fluid flow along the vascular network. Molecular mechanisms involved in the formation of a vascular lumen of appropriate size, or tubulogenesis, are still only partially understood. Src homology 2 domain containing E (She) protein was previously identified in a screen for proteins that interact with Abelson (Abl)-kinase.

Elucidating the Morphogenic and Signaling Roles of Defined Growth Factors Controlling Human Endothelial Cell Lumen Formation Versus Sprouting Behavior.

Five growth factors [ie, insulin, fibroblast growth factor-2 (FGF-2), stem cell factor, IL-3, and stromal-derived factor 1α] in combination are necessary for human endothelial cells (ECs) to undergo tube morphogenesis, a process requiring both lumen formation and sprouting behavior. This study investigated why these factors are required by subdividing the factors into 4 separate groups: insulin-only, insulin and FGF-2, no FGF-2 (all factors but without FGF-2), and all factors. The study found that the insulin-only condition failed to support EC morphogenesis or survival, the insulin and FGF-2 condition supported primarily EC lumen formation, and the no FGF-2 condition supported EC sprouting behavior.

Meningeal CSF transport is primarily mediated by the arachnoid and pia maters during development.

Background: The recent characterization of the glymphatic system and meningeal lymphatics has re-emphasized the role of the meninges in facilitating CSF transport and clearance. Here, we characterize small and large CSF solute distribution patterns along the intracranial and surface meninges in neonatal rodents and compare our findings to a rodent model of intraventricular hemorrhage-posthemorrhagic hydrocephalus. We also examine CSF interactions with the tela choroidea and its pial invaginations into the choroid plexuses of the lateral, third, and fourth ventricles.

Orientation, electronic decoupling and band dispersion of heptacene on modified and nanopatterned copper surfaces.

The adsorption of heptacene (7 A) on Cu(110) and Cu(110)-(2 × 1)-O was studied with scanning tunneling microscopy, photoemission orbital tomography and density functional calculations to reveal the influence of surface passivation on the molecular geometry and electronic states. We found that the charge transfer into the 7 A molecules on Cu(110) is completely suppressed for the oxygen-modified Cu surface. The molecules are aligned along the Cu-O rows and uncharged.

Fecal Calprotectin Concentrations in Cats with Chronic Enteropathies.

Diagnosis of feline chronic inflammatory enteropathies (CIE) and the differentiation from small cell intestinal lymphoma (SCL) can be challenging. Intestinally expressed calprotectin (S100A8/A9 protein complex) appears to be part of the complex pathogenesis of feline chronic enteropathies (FCE). Fecal calprotectin is a non-invasive biomarker for intestinal inflammation in humans and dogs but has not yet been evaluated in cats.

SH2 domain protein E (SHE) and ABL signaling regulate blood vessel size.

Blood vessels in different vascular beds vary in lumen diameter, which is essential for their function and fluid flow along the vascular network. Molecular mechanisms involved in the formation of a vascular lumen of appropriate size, or tubulogenesis, are still only partially understood. protein was previously identified in a screen for proteins that interact with Abelson (Abl)-kinase.

Unemployment and Substance Use: An Updated Review of Studies from North America and Europe.

Since the industrial revolution, the relationship between unemployment and psychiatric disorders has been a subject of high interest. Currently, regarding the correlation between unemployment and substance-use disorders (SUDs), only older, often isolated and fragmented research results are available in the literature. This review was based on an extensive literature search of the European and North American literature in most relevant databases for "unemployment" and "substance use" related to "drugs", "alcohol", "nicotine", and "tobacco" between November 2022 and January 2023, according to the PRISMA (Preferred Reporting Items for Systematic review and Meta-Analysis) guidelines.

A self-etch bonding system with potential to eliminate selective etching and resist proteolytic degradation.

Objectives: Bonded restorations using self-etch (SE) systems exhibit a limited lifespan due to their susceptibility to hydrolytic, enzymatic or fatigue degradation and poor performance on enamel. This study was conducted to develop and assess the performance of a two-step SE system using a functional monomer bis[2-(methacryloyloxy)ethyl]phosphate (BMEP) and demonstrate a strategy to enhance stability of bonded resin composite restorations to both enamel and dentine.

Methods: A two-step SE system was formulated with a primer containing BMEP, with an adhesive with or without BMEP, and compared to a commercial 10-MDP-containing system, Clearfil SE Bond 2 (CFSE).

A Residual Marker of Cognitive Reserve Is Associated with Resting-State Intrinsic Functional Connectivity Along the Alzheimer's Disease Continuum.

Background: Cognitive reserve (CR) explains inter-individual differences in the impact of the neurodegenerative burden on cognitive functioning. A residual model was proposed to estimate CR more accurately than previous measures. However, associations between residual CR markers (CRM) and functional connectivity (FC) remain unexplored.
