The effects of flow settings during high-flow nasal cannula oxygen therapy for neonates and young children.

Background: During neonatal and paediatric high-flow nasal cannula therapy, optimising the flow setting is crucial for favourable physiological and clinical outcomes. However, considerable variability exists in clinical practice regarding initial flows and subsequent adjustments for these patients. Our review aimed to summarise the impact of various flows during high-flow nasal cannula treatment in neonates and children.

Efficacy and safety of established and off-label ADHD drug therapies for cognitive impairment or attention-deficit hyperactivity disorder symptoms in bipolar disorder: A systematic review by the ISBD Targeting Cognition Task Force.

Background: Abnormalities in dopamine and norepinephrine signaling are implicated in cognitive impairments in bipolar disorder (BD) and attention-deficit hyperactivity disorder (ADHD). This systematic review by the ISBD Targeting Cognition Task Force therefore aimed to investigate the possible benefits on cognition and/or ADHD symptoms and safety of established and off-label ADHD therapies in BD.

Methods: We included studies of ADHD medications in BD patients, which involved cognitive and/or safety measures.

The neuroprotective and neuroplastic potential of glutamatergic therapeutic drugs in bipolar disorder.

The monoamine hypothesis has dominated research on the pathophysiology of mood disorders as well as the development of therapeutic drugs by over half a century. Nowadays a change of perspective is taking place. The glutamate system is increasingly implicated in the pathophysiology of mood disorders.

Laparoscopic surgery: A randomised controlled trial comparing intraoperative hemodynamic parameters and arterial-blood gas changes at two different pneumoperitoneal pressure values.

Background: The benefits of laparoscopic surgery are well known. However, clinic and metabolic consequences of pneumoperitoneum, achieved by insufflation of gas carbon dioxide, are still debated. Cardiovascular system suffering due to the compression of intra-abdominal venous structures can cause life-threatening complications.

Observing and modeling long-term persistence of P. noctiluca in coupled complementary marine systems (Southern Tyrrhenian Sea and Messina Strait).

In the Mediterranean Sea, the Strait of Messina (MS) is a very peculiar area, connecting highly different regions and representing a privileged observatory for an early comprehension and assessment of ecosystems shifts. It is hypothesized that the outbreaks observed near the coast of many sites in the Mediterranean Sea may be the result of transport of permanent populations of P. noctiluca in pelagic waters to the coast, caused by specific hydrodynamic conditions.

High-Flow Nasal Cannula Reduces Effort of Breathing But Not Consistently via Positive End-Expiratory Pressure.

Background: High-flow nasal cannula (HFNC) therapy reduces the effort of breathing in patients with bronchiolitis, but the mechanisms are not understood. Theorized mechanisms include dead space washout and positive end-expiratory pressure (PEEP) application.

Research Question: What are the mechanisms of action of HFNC therapy in patients with bronchiolitis?

Study Design And Methods: Prospective, single-center study of children 3 years of age or younger with bronchiolitis from January 2020 through March 2021.

Tracheobronchial Foreign Body Aspiration Diagnosed with Electrical Impedance Tomography.

Background: Foreign body aspiration (FBA) in children has a high morbidity, and early diagnosis is the key for preventing acute and chronic respiratory complications. To diagnose FBA, commonly used imaging modalities have limited negative predictive value, and rigid bronchoscopy remains as the gold standard. We present a case where the diagnosis of FBA was made in a novel way with electrical impedance tomography (EIT).

Evaluating endophenotypes for bipolar disorder.

Background: Phenotypic heterogeneity is a major impediment to the elucidation of the neurobiology and genetics of bipolar disorder. Endophenotype could help in reducing heterogeneity by defining biological traits that are more direct expressions of gene effects. The aim of this review is to examine the recent literature on clinical, epidemiological, neurobiological, and genetic findings and to select and evaluate candidate endophenotypes for bipolar disorder.

Ecological assessment of anthropogenic impact in marine ecosystems: The case of Bagnoli Bay.

Pollutants alter marine systems, interfering with provisioning of ecosystem services; understanding their interaction with ecological communities is therefore critical to inform environmental management. Here we propose a joint compositional- and interaction-based analysis for ecological status assessment and apply it on the benthic communities of the Bagnoli Bay. We found that contamination differentially affects the communities' composition in the bay, with prokaryotes influenced only by depth, and benthos not following the environmental gradient at all.

The Otranto Channel (South Adriatic Sea), a hot-spot area of plankton biodiversity: pelagic polychaetes.

Composition, density and specimen sizes of pelagic polychaete assemblages were analyzed in the Southern Adriatic Sea. The study was based on finely stratified vertical (0-1100 m) and spatial sampling (17 stations) representing spring conditions. Holoplanktonic polychaetes were distributed in both neritic and pelagic waters, although the highest densities were observed along the Otranto Channel.

Neuropsychological Performance in Alcohol Dependent Patients: A One-Year Longitudinal Study.

Objective: Despite several studies that have highlighted the harmful effects of alcohol consumption on cognitive functions it remains unclear whether certain brain areas are more sensitive than others are or whether alcohol causes widespread cognitive deficit. Moreover, the role of continued abstinence has yet to be clarified regarding the quality of recovery on the different cognitive domains. The aim of this 1-year longitudinal study was to evaluate the recovery of cognitive deficits in the medium (6 months) and long term (12 months) after the interruption of drinking.

A meta-analysis of cognitive performance in melancholic versus non-melancholic unipolar depression.

Background: Recently there is increasing recognition of cognitive dysfunction as a core feature of Major Depressive Disorder (MDD). The goal of the current meta-analysis was to review and examine in detail the specific features of cognitive dysfunction in Melancholic (MEL) versus Non-Melancholic (NMEL) MDD.

Methods: An electronic literature search was performed to find studies comparing cognitive performance in MEL versus NMEL.

Pharmacological treatments in alcohol use disorders: state of art and new perspectives.

The main focus of this narrative review is to present and discuss the most relevant clinical data about the pharmacological therapy for alcohol use disorders. By using PubMed we conducted a review of the clinical literature on drugs related to alcohol use disorders. All data are presented following the three phases of treatment: a) from withdrawal to abstinence; b) abstinence and relapse prevention; c) reduction of alcohol consumption.

Clinical insights by the presence of bipolar disorder in pseudohypoparathyroidism type 1A.

Pseudohypoparathyroidism type 1A and its association with bipolar disorder (BD) have never been reported so far. We report a new case with both clinical entities and discuss the potential pathophysiological mechanisms of this association (protein kinase A hypoactivation, parathyroid hormone, hypocalcemia, protein kinase C activation, vitamin D deficiency). In this patient, the correction of the underlying calcium and vitamin D deficiencies leads to a better BD outcome and lower dosage of psychopharmacological agents.

Topiramate in Alcohol Use Disorders: Review and Update.

To date, a limited number of pharmacological agents exist to treat alcohol use disorders (AUDs), and there is growing interest in new therapeutic tools. In this framework, topiramate may represent a useful treatment option, although its use is not yet approved for AUDs. The main focus of this review is to discuss all the existing data supporting the use of topiramate in AUDs, with an emphasis on the most recent and relevant clinical implications.

Co-occurrence of alcohol use disorder and behavioral addictions: relevance of impulsivity and craving.

Purpose: The aims of the study were to evaluate the occurrence of behavioral addictions (BAs) in alcohol use disorder (AUD) subjects and to investigate the role of impulsivity, personality dimensions and craving.

Methods: 95 AUD outpatients (DSM-5) and 140 homogeneous controls were assessed with diagnostic criteria and specific tests for gambling disorder, compulsive buying, sexual, internet and physical exercise addictions, as well as with the Barratt Impulsiveness Scale (BIS-11) and Temperamental and Character Inventory-Revised (TCI-R). The Obsessive Compulsive Drinking Scale (OCDS) and Visual Analogue Scale for craving (VASc) were also administered to the AUD sample.

Cognitive markers of psychotic unipolar depression: a meta-analytic study.

Background: The goal of the current meta-analysis was to review and examine in detail the features of cognitive performance in psychotic (MDDP) versus non-psychotic (MDD) major depressive disorder.

Methods: An electronic literature search was performed to find studies comparing cognitive performance in MDDP versus MDD. A meta-analysis of broad cognitive domains (processing speed, reasoning/problem solving, verbal learning, visual learning, attention/working memory) and individual cognitive tasks was conducted on all included studies (n=12).

Low-dose topiramate in alcohol dependence: a single-blind, placebo-controlled study.

Introduction: Topiramate (TOP) and anticonvulsants in general are considered safe and effective drugs for the treatment of alcohol dependence, even though TOP-induced adverse events are quite common, especially for high initial doses or if titration to 300 mg/d is too rapid. The aim of the present study was to assess the efficacy and tolerability profile of low-dose TOP for relapse prevention.

Methods: After detoxification, 52 patients were randomized into 2 groups as follows: 26 patients received 100 mg of TOP (oral, twice daily), titrated over 2 weeks, and 26 patients received placebo (PLA).

Imaging studies on dopamine transporter and depression: a review of literature and suggestions for future research.

We review the conflicting results from imaging studies of dopamine transporter availability in depressed patients and also discuss the heterogeneity of the variables involved. Major depression includes diverse clinical manifestations and in recent years there has been an increasing interest in the identification of homogeneous phenotypes and different clinical subtypes of depression, e.g.

A possible new option for migraine management: agomelatine.

Background: Migraine is a primary headache disorder characterized by recurrent episodes of headache associated with gastrointestinal, neurologic, and autonomic symptoms. Some evidence in literature suggests that the melatonergic system possibly plays an important role in the pathogenesis of migraine. Few studies have been performed on the use of melatonin as an antimigraine agent.
