Heart Rate Variability as a Potential Predictor of Response to Intranasal Esketamine in Patients with Treatment-Resistant Depression: A Preliminary Report.

Esketamine has received approval as a nasal spray (ESK-NS) for treatment-resistant depression (TRD) and evidence from real-world investigations has confirmed the effectiveness of ESK-NS, albeit with interindividual differences in response. Heart rate variability (HRV), defined as the fluctuation in time interval between consecutive heartbeats, can be used to measure autonomic dysfunction in psychiatric disorders and its role has been investigated in diagnosis and prognosis of depression. This preliminary report aims to evaluate HRV parameters and their association with treatment outcome in 18 patients (55.

Investigating the Effectiveness of Brexpiprazole in Subjects with Schizophrenia Spectrum Illness and Co-Occurring Substance Use Disorder: A Prospective, Multicentric, Real-World Study.

Background: Dual disorders (DDs) involve the coexistence of a substance use disorder (SUD) with another mental illness, often from the psychotic and affective categories. They are quite common in clinical practice and present significant challenges for both diagnosis and treatment. This study explores the effectiveness of brexpiprazole, a third-generation antipsychotic, in an Italian sample of individuals diagnosed with schizophrenia spectrum disorder and a comorbid SUD.

Substance use disorders in adults with attention-deficit/hyperactivity disorder: The role of affective temperament.

Objective: Substance Use Disorders (SUD) are common in adults with Attention-Deficit/Hyperactivity Disorder (ADHD). Although predictors of SUD in this population are relevant for prevention and treatment, they need further clarification. Affective temperaments potentially associated with SUD in adult ADHD patients were explored.

The Patient's Perspective on the Effects of Intranasal Esketamine in Treatment-Resistant Depression.

The effectiveness of the esketamine nasal spray (ESK-NS) for treatment-resistant depression (TRD) has been confirmed by real-world studies. Available evidence derived from clinician-rated assessments might differ from patients' perceptions about the helpfulness of treatments. We aimed to verify the effect of ESK-NS from patients' view in 25 TRD patients (56% males, 55.

Predictors of polysubstance use in patients with severe alcohol use disorder: the role of reward craving.

Background: Different craving typologies (i.e., reward, relief, obsessive) have been identified in alcohol use disorder (AUD) but have been less investigated in specific populations like AUD patients with polysubstance use (PSU).

Reduction in Cognitive Symptoms Following Intranasal Esketamine Administration in Patients With Chronic Treatment-resistant Depression: A 12-Week Case Series.

Background: Cognitive symptoms are a core feature of depressive disorders, interfere with full functional recovery and are prominent in patients with treatment-resistant depression (TRD), particularly in severe chronic cases. Intranasal (IN) esketamine was recently approved for the treatment of TRD; however, its effects on cognitive symptoms are unclear. In this article, we describe cognitive changes in 8 patients with chronic TRD who were treated with IN administration of esketamine.

Adaptation of the binding domain of S-layer protein as a molecular tag for affinity chromatography development.

Introduction: The S-layer proteins are a class of self-assembling proteins that form bi-dimensional lattices named S-Layer on the cell surface of bacteria and archaea. The protein SlpA, which is the major constituent of the S-layer, contains in its C-terminus region (SlpA), a protein domain (named here as SLAP) responsible for the association of SlpA to the bacterial surface. SLAP was adapted for the development of a novel affinity chromatography method: the SLAP-based affinity chromatography (SAC).

Effect of affective temperament on illness characteristics of subjects with bipolar disorder and major depressive disorder.

Background: Affective temperaments represent the stable, biologically determined substrates of mood disorders. The relationship between affective temperaments and bipolar disorder (BD) or major depressive disorder (MDD) has been described. However, the strength of such relationship should be tested while considering other factors influencing the diagnosis of BD/MDD.

Physical and cognitive correlates, inflammatory levels, and treatment response in post-COVID-19 first-onset vs. recurrent depressive episodes.

Psychiatric symptoms have been frequently reported in patients affected by COVID-19, both as new occurring and recurrences of pre-existing diseases. Depressive symptoms are estimated to affect at least 30% of patients following infection, with specific physical and cognitive features and relevant immune-inflammatory alterations. This study aimed to retrospectively characterize post-COVID-19 first-onset and recurrent major depressive episodes (MDE) and to evaluate the effects of antidepressants on physical and cognitive correlates of depression, in addition to mood, anxiety, and underlying inflammatory status.

Update on Pharmacological Treatment for Comorbid Major Depressive and Alcohol Use Disorders: The Role of Extended-release Trazodone.

Background: Major Depressive Disorder (MDD) and Alcohol Use Disorder (AUD) are major public health concerns because of their high prevalence and clinical and functional severity. MDD and AUD commonly co-occur, but effective therapeutic approaches for comorbidity are still scarce. Available evidence on selective serotonin reuptake inhibitors and tricyclic antidepressants held mixed results, and further pharmacological categories have been less investigated.

Vortioxetine improves physical and cognitive symptoms in patients with post-COVID-19 major depressive episodes.

Major Depressive Episodes (MDE) following COVID-19 are frequent, can have a characteristic clinical picture, and are associated with immune-inflammatory changes. Vortioxetine is known to improve physical and cognitive performance in patients with depression and shows anti-inflammatory and anti-oxidative activities. This study aimed to retrospectively evaluate the effects of vortioxetine after 1 and 3 months of treatment in 80 patients (44.

Reversible adhesion by type IV pili leads to formation of permanent localized clusters.

The formation of long-lived, multicellular clusters is a fundamental step in the physiopathology of many disease-causing bacteria. Experiments on abiotic surfaces suggest that bacterial colonization, including initial cluster formation, requires (1) irreversible adhesion, (2) cell proliferation, and (3) a phenotypic transition. However, here we show that on infection of a polarized MDCK epithelium, (PA) forms long-lived - i.

Trait-Related Impulsivity, Affective Temperaments and Mood Disorders: Results from a Real-World Multicentric Study.

Trait-related impulsiveness is highly prevalent in patients with mood disorders, being associated with negative outcomes. The predictive role of affective temperaments on trait-related impulsivity is still understudied. The aim of the present study is to investigate the relationship between impulsivity and affective temperaments in a sample of euthymic patients with mood disorders.

Evaluating Craving in Alcohol Use Disorder: Psychometric Characteristics of the Craving Typology Questionnaire-15 (CTQ-15).

Aims: The Craving Typology Questionnaire (CTQ) is a psychometric instrument used to assess alcohol craving in normal controls and subjects with alcohol use disorder (AUD). It allows a dimensional self-rating assessment of craving according to a three-pathway psychobiological model of craving distinguishing craving into a reward, relief and obsessive component. The aim of the present study is to evaluate psychometric properties of the CTQ-15, a revised version of CTQ with 15 items.

Impulsivity and alexithymia predict early versus subsequent relapse in patients with alcohol use disorder: A 1-year longitudinal study.

Introduction: Longitudinal psychopathological predictors of relapse in alcohol use disorder are unclear.

Methods: Relapses, sociodemographic and psychopathological risk factors were assessed in 171 alcohol use disorder outpatients within a 1-year follow up. Impulsivity and alexithymia were evaluated using the Barratt Impulsiveness Scale and the Toronto Alexithymia Scale, respectively.

Evaluation of qualitative and quantitative taste alterations in COVID-19.

A large percentage of coronavirus disease 2019 (COVID-19) patients have taste dysfunction. Interleukin 6 (IL-6) levels in mild and moderate COVID-19 patients with the type (quantitative or qualitative) of taste disorders were compared in this observational study. The 208 COVID-19 patients (118 men and 90 women) revealing only taste dysfunctions as prodromic symptoms were classified as mild and moderate patients.

Effect of Water Stress on Physiological and Morphological Leaf Traits: A Comparison among the Three Widely-Spread Invasive Alien Species , and .

Invasive alien species (IAS) are a problem, especially in drought-prone environments such as the Mediterranean Basin where the exacerbation of the already severe conditions could constrain the native species acclimatation degree, creating new opportunities for IAS. Climate change may drive IAS expansions, even if different IAS can vary in their acclimatation response. Thus, it is important to obtain a broader insight of how the different IAS face abiotic stress.

Daily Temperature Effect on Seedling Growth Dynamic of Three Invasive Alien Species.

A greater relative growth rate (RGR) is positively correlated with a species' ability to deploy a larger leaf area either due to a greater total number of leaves (LN) in the canopy or due to an average size of individual leaves (LA). This study aimed to analyze and compare, (1) the temporal (i.e.

Cerebral edema in acute stroke: Effect of thrombolytic treatment.

Cerebral edema (CED) is a common complication of ischemic stroke in Intensive Care Unit. Although frequently observed in patients undergoing intravenous thrombolytic (IVT) treatment, the pathogenic role of recombinant tissue plasminogen activator (rtPA) in CED induction has not yet been definitively clarified. The aim of our study is to verify the relationship between CED and rtPA in patients affected by acute ischemic stroke, without reperfusion signs, evaluating the CED growth rate in the first week after stroke onset.

Development of a Salmonella-based oral vaccine to control intestinal colonization of Shiga-toxin-producing Escherichia coli (STEC) in animals.

Shiga-toxin-producing Escherichia coli (STEC) is an important food-borne pathogen that causes hemorrhagic colitis and hemolytic uremic syndrome (HUS) in humans. Since no vaccines are available and antibiotic treatment is not recommended because promotes the appearance of HUS symptoms, the control of STEC intestinal colonization in cows, which is an important environmental reservoir, is crucial to control this zoonosis. Here, we evaluated the adaptation of an attenuated strain of Salmonella enterica serovar Typhimurium (ΔaroA mutant) as a vaccine platform for preventing STEC intestinal colonization that was studied in a mouse model.
