Use of patient portals to disclose STI test histories to sex partners among U.S. men who have sex with men: A call for research and guidance.

Background: This study investigates the use of patient portals for disclosing sexually transmitted infection (STI) test result histories to sexual partners among men who have sex with men (MSM) in the United States.

Methods: Using data from the 2022-2023 American Men's Internet Survey, this cross-sectional analysis examined demographic, behavioral, and healthcare-related factors associated with MSM's utilization of patient portals for sharing STI test results. Participants ( = 2601) were surveyed on portal use, STI testing frequency, and partner disclosure practices.

Association between homelessness and PrEP uptake among men who have sex with men: Results from the American Men's Internet Survey, 2017-2021.

Background: Gay, bisexual, and other men who have sex with men (GBMSM) are disproportionately affected by housing insecurity across the US. This study examined the association between homelessness and uptake of pre-exposure prophylaxis (PrEP) for HIV prevention among GBMSM in the United States and investigated the modifying effect of injection drug use.

Methods: 47,750 cisgender GBMSM who participated in the American Men's Internet Survey from 2017 to 2021 and who self-reported not living with HIV were included in this secondary, cross-sectional analysis.

Potential gains in PrEP coverage and effect on racial disparities following introduction of on-demand and long-acting injectable PrEP: Preferences of men who have sex with men in the United States, 2021-2022.

Introduction: There are persistent race- and ethnicity-based disparities in HIV incidence among gay and bisexual men who have sex with men (GBMSM) in the United States, partially driven by inequities in distribution of pre-exposure prophylaxis (PrEP). We assessed how additional modalities of PrEP beyond daily oral might affect uptake of PrEP and ongoing disparities in HIV incidence in the US.

Methods: In an online survey of GBMSM in the US, we presented participants with descriptions of each PrEP modality.

As the demand for more efficient and sustainable processes grows, better catalysts are needed. Understanding the working principles of catalysts is key, and over the last 50 years, surface-enhanced Raman Spectroscopy (SERS) has become essential.

Rethinking cutoff values for the South Oaks Gambling Screen: Sex-specific insights and DSM-5 severity adjustments in Gambling Disorder assessment.

Background And Aims: The South Oaks Gambling Screen (SOGS) is a commonly used tool for screening potential gambling problems. The SOGS score has been found to be correlated with the DSM-5 criteria for Gambling Disorder (GD). However, one of its main limitations is the high rate of false positives.

A Self-Applied Psychological Treatment for Gambling-Related Problems via The Internet: A Pilot, Feasibility Study.

The main purpose of this study was to evaluate the feasibility of an online psychological intervention for individuals with gambling-related problems, supported by ecological momentary assessments and interventions (EMAs and EMIs), along with weekly phone-calls, before conducting a randomized controlled trial. Participants were required to complete 3 of the 8 modules of the program based on cognitive-behavioral therapy (CBT) and extensions and innovations of CBT. The study measured the outcomes of feasibility (i.

Network analysis of DSM-5 criteria for gambling disorder: considering sex differences in a large clinical sample.

Background: The fifth version of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) and its revised version (DSM-5-TR) propose severity levels for gambling disorder (GD) based on the number of criteria met. However, this taxonomy has some limitations. We aimed to assess the centrality of each criterion and its relationship by conducting a network analysis while considering sex differences.

Eating disorders and obesity: bridging clinical, neurobiological, and therapeutic perspectives.

Eating disorders (EDs) and obesity are complex health conditions sharing various risk and maintenance factors, intensified in cases of comorbidity. This review explores the similarities and connections between these conditions, examining different facets from a multidisciplinary perspective, among them comorbidities, metabolic and psychological factors, neurobiological aspects, and management and therapy implications. We aim to investigate the common characteristics and complexities of weight and EDs and explore their interrelationships in individuals who experience both.

Association between endocrine and neuropsychological endophenotypes and gambling disorder severity.

Background: Neurobiological characteristics have been identified regarding the severity of gambling disorder (GD). The aims of this study were: (1) to examine, through a path analysis, whether there was a relationship between neuroendocrine features, potentially mediational GD variables, and GD severity, and (2) to associate neuroendocrine variables, with GD severity-related variables according to gambling preferences.

Methods: The sample included 297 outpatients with GD.

Confining calcium oxalate crystal growth in a carbonated apatite-coated microfluidic channel to better understand the role of Randall's plaque in kidney stone formation.

Effective prevention of recurrent kidney stone disease requires the understanding of the mechanisms of its formation. Numerous observations have demonstrated that a large number of pathological calcium oxalate kidney stones develop on an apatitic calcium phosphate deposit, known as Randall's plaque. In an attempt to understand the role of the inorganic hydroxyapatite phase in the formation and habits of calcium oxalates, we confined their growth under dynamic physicochemical and flow conditions in a reversible microfluidic channel coated with hydroxyapatite.

Critical transitions in the Amazon forest system.

The possibility that the Amazon forest system could soon reach a tipping point, inducing large-scale collapse, has raised global concern. For 65 million years, Amazonian forests remained relatively resilient to climatic variability. Now, the region is increasingly exposed to unprecedented stress from warming temperatures, extreme droughts, deforestation and fires, even in central and remote parts of the system.

Electrochemical Tip-Enhanced Raman Spectroscopy for the Elucidation of Complex Electrochemical Reactions.

Tip-enhanced Raman spectroscopy (TERS) is an emerging nanospectroscopy technique whose implementation in situ/, namely, in the liquid phase and under electrochemical polarization (EC-TERS), remains challenging. The investigation of electrochemical processes at the nanoscale, in real time and over wide potential windows can be of particular interest but tedious when using EC-STM-TERS. This approach was successfully applied to the investigation of a well-established but yet complex system (a thiolated nitrobenzene derivative 4-NBM) whose reduction mechanism involves various multistep reaction paths, most likely pH-dependent.

Familiarity Processing through Faces and Names: Insights from Multivoxel Pattern Analysis.

The way our brain processes personal familiarity is still debatable. We used searchlight multivoxel pattern analysis (MVPA) to identify areas where local fMRI patterns could contribute to familiarity detection for both faces and name categories. Significantly, we identified cortical areas in frontal, temporal, cingulate, and insular areas, where it is possible to accurately cross-classify familiar stimuli from one category using a classifier trained with the stimulus from the other (i.

Plasma concentration of leptin is related to food addiction in gambling disorder: Clinical and neuropsychological implications.

Background: Data implicate overlaps in neurobiological pathways involved in appetite regulation and addictive disorders. Despite different neuroendocrine measures having been associated with both gambling disorder (GD) and food addiction (FA), how appetite-regulating hormones may relate to the co-occurrence of both entities remain incompletely understood.

Aims: To compare plasma concentrations of ghrelin, leptin, adiponectin, and liver-expressed antimicrobial peptide 2 (LEAP-2) between patients with GD, with and without FA, and to explore the association between circulating hormonal concentrations and neuropsychological and clinical features in individuals with GD and FA.

Cluster analysis in gambling disorder based on sociodemographic, neuropsychological, and neuroendocrine features regulating energy homeostasis.

Background: The heterogeneity of gambling disorder (GD) has led to the identification of different subtypes, mostly including phenotypic features, with distinctive implications on the GD severity and treatment outcome. However, clustering analyses based on potential endophenotypic features, such as neuropsychological and neuroendocrine factors, are scarce so far.

Aims: This study firstly aimed to identify empirical clusters in individuals with GD based on sociodemographic (i.

Anandamide and 2-arachidonoylglycerol baseline plasma concentrations and their clinical correlate in gambling disorder.

Introduction: Different components of the endocannabinoid (eCB) system such as their most well-known endogenous ligands, anandamide (AEA) and 2-arachidonoylglycerol (2-AG), have been implicated in brain reward pathways. While shared neurobiological substrates have been described among addiction-related disorders, information regarding the role of this system in behavioral addictions such as gambling disorder (GD) is scarce.

Aims: Fasting plasma concentrations of AEA and 2-AG were analyzed in individuals with GD at baseline, compared with healthy control subjects (HC).

Impulsivity and compulsivity in gambling disorder and bulimic spectrum eating disorders: Analysis of neuropsychological profiles and sex differences.

Background: Gambling disorder (GD) and bulimic spectrum eating disorders (BSDs) not only share numerous psychopathological, neurobiological, and comorbidity features but also are distinguished by the presence of inappropriate behaviours related to impulsivity and compulsivity. This study aimed to emphasise the differences and similarities in the main impulsivity and compulsivity features between GD and BSD patients, and to analyse the potential influence of sex in these domains.

Methods: Using self-reported and neurocognitive measures, we assessed different impulsive-compulsive components in a sample of 218 female and male patients (59 with BSD and 159 with GD) and 150 healthy controls.

Cognitive flexibility and DSM-5 severity criteria for eating disorders: assessing drive for thinness and duration of illness as alternative severity variables.

Background: The severity criteria for eating disorders (EDs) proposed in the DSM-5 have been established without sufficient empirical support. Drive for thinness (DT) and duration of illness have been proposed as two alternative severity measures, however their empirical evidence is also limited. To date, no research has assessed the validity of current eating disorder (ED) severity criteria regarding cognitive flexibility factors.

Ketamine subcutaneous continuous infusion for non-cancer neuropathic pain at home: a case report.

Objective: Ketamine is a drug that can effectively treat neuropathic pain by blocking the N-methyl-D-aspartate receptor. It has been studied as a supplement to opioids for cancer pain, but its effectiveness for non-cancer pain is still limited. However, despite its usefulness in managing refractory pain, ketamine is not commonly used for home-based palliative care.

[Stuttering in Children: Review and Referral Criteria].

Stuttering is a speech fluency disorder, in which people know perfectly well the message they want to convey, even though their speech is characterized by changes in rhythm, repetitions, prolongations, pauses and blocks, and may also be associated with states of anxiety or emotional tension. Up to one in every six children, typically between two and five years old, experience a period of transitory speech disfluency, with usual spontaneous recovery before reaching school age, with a prevalence rate of stuttering of up to 1% of the adult population, and a higher incidence rate in males (4:1). In Portugal, it is estimated that stuttering affects around 100 thousand people, acquiring importance due to its frequency and association with lower self-esteem, anxiety and social isolation, with negative impact on people's ability to communicate and on their well-being and social interactions.

Applying psycho-behavioural phenotyping in obesity characterization.

Individual differences in obesity, beyond being explained by metabolic and medical complications, are understood by alterations in eating behaviour which underlie psychological processes. From this psychological perspective, studies have identified several potential characteristic features at the psycho-behavioural level that could additionally explain the maintenance of chronic excess weight or the unsuccessful results of current treatments. To date, despite the growing evidence, the heterogeneity of the psychological evidence associated with obesity has made it challenging to generate consensus on whether these psycho-behavioural phenotypes can be a complement to improve outcomes of existing interventions.

Nitrogen management in farming systems under the use of agricultural wastes and circular economy.

Population growth leads to an increase in the demand for energy, water, and food as cities grow and urbanize. However, the Earth's limited resources are unable to meet these rising demands. Modern farming practices increase productivity, but waste resources and consume too much energy.

Gambling disorder duration and cognitive behavioural therapy outcome considering gambling preference and sex.

Gambling Disorder (GD) is a behavioural addiction that leads to high level of clinical distress and, in general, it is characterized by enduring symptomatology that presents high rates of chronicity. However, there is high variability of illness duration among patients who seek treatment for GD. Previous studies reported mixed results about the relevance of illness duration in GD treatment outcome.

Are Signals Regulating Energy Homeostasis Related to Neuropsychological and Clinical Features of Gambling Disorder? A Case-Control Study.

Gambling disorder (GD) is a modestly prevalent and severe condition for which neurobiology is not yet fully understood. Although alterations in signals involved in energy homeostasis have been studied in substance use disorders, they have yet to be examined in detail in GD. The aims of the present study were to compare different endocrine and neuropsychological factors between individuals with GD and healthy controls (HC) and to explore endocrine interactions with neuropsychological and clinical variables.
