An Orai1 gain-of-function tubular aggregate myopathy mouse model phenocopies key features of the human disease.

Tubular aggregate myopathy (TAM) is a heritable myopathy primarily characterized by progressive muscle weakness, elevated levels of creatine kinase (CK), hypocalcemia, exercise intolerance, and the presence of tubular aggregates (TAs). Here, we generated a knock-in mouse model based on a human gain-of-function mutation which results in a severe, early-onset form of TAM, by inducing a glycine-to-serine point mutation in the ORAI1 pore (Orai1 or GS mice). By 8 months of age, GS mice exhibited significant muscle weakness, exercise intolerance, elevated CK levels, hypocalcemia, and robust TA presence.

Safeguarding nurses' mental health: The critical role of psychosocial safety climate in mitigating relational stressors and exhaustion.

Burnout among nurses is a pervasive concern in healthcare, with profound implications for patient care and nurse well-being. While research has highlighted the detrimental effects of burnout on many aspects of nursing, including patient safety and quality of care, the underlying mechanisms driving burnout warrant further investigation. In this cross-sectional study, we surveyed 196 nurses from diverse Italian hospitals using an online questionnaire via Qualtrics.

Risk of Recurrent Venous Thromboembolism in Patients with Cancer: An Individual Patient Data Meta-analysis and Development of a Prediction Model.

Background:  About 7% of patients with cancer-associated venous thromboembolism (CAT) develop a recurrence during anticoagulant treatment. Identification of high-risk patients may help guide treatment decisions.

Aim:  To identify clinical predictors and develop a prediction model for on-treatment recurrent CAT.

Brimonidine Eye Drops within the Reach of Children: A Possible Foe.

Brimonidine, a selective alpha-2 adrenergic agonist used for the treatment of open-angle glaucoma, has been shown to cause neurological side effects such as unresponsiveness, lethargy, hypoventilation, and stupor, mimicking opioid toxicity. We report one case of transient encephalopathy in a toddler, in whom accidental brimonidine toxicity was suspected and then confirmed by a toxicology study. The healthy 8-month-old girl was taken to the pediatric ER since she was drowsy and hypotonic with miosis.

Hypoxic Functional Regulation Pathways in the GI Tract: Focus on the HIF-1α and Microbiota's Crosstalk.

Hypoxia is an essential gastrointestinal (GI) tract phenomenon that influences both physiologic and pathologic states. Hypoxia-inducible factors (HIFs), the primary drivers of cell adaptation to low-oxygen environments, have been identified as critical regulators of gut homeostasis: directly, through the induction of different proteins linked to intestinal barrier stabilization (ie, adherent proteins, tight junctions, mucins, integrins, intestinal trefoil factor, and adenosine); and indirectly, through the regulation of several immune cell types and the modulation of autophagy and inflammatory processes. Furthermore, hypoxia and HIF-related sensing pathways influence the delicate relationship existing between bacteria and mammalian host cells.

Pre-TAVI imaging: an Italian survey by the CT PRotocol optimization (CT-PRO) group.

Purpose: The purpose of this survey was to evaluate the current state-of-art of pre-TAVI imaging in a large radiological professional community.

Methods: Between December 2022 and January 2023 all members of the Italian Society of Medical and Interventional Radiology (SIRM) were invited by the CT PRotocol Optimization group (CT-PRO group) to complete an online 24-item questionnaire about pre-TAVI imaging.

Results: 557 SIRM members participated in the survey.

Improved Quantum-Classical Treatment of N-N Inelastic Collisions: Effect of the Potentials and Complete Rate Coefficient Data Sets.

In this study, complete (, including all vibrational quantum numbers in an N vibrational ladder) data sets of vibration-to-vibration and vibration-to-translation rate coefficients for N-N collisions are explicitly computed along with transport properties (shear and bulk viscosity, thermal conductivity, and self-diffusion) in the temperature range 100-9000 K. To reach this goal, we improved a mixed quantum-classical (MQC) dynamics approach by lifting the constraint of a Morse treatment of the vibrational wave function and intramolecular potential and permitting the use of more realistic and flexible representations. The new formulation has also allowed us to separately analyze the role of intra- and intermolecular potentials on the calculated rates and properties.

Hypoglycemia in Children: Major Endocrine-Metabolic Causes and Novel Therapeutic Perspectives.

Hypoglycemia is due to defects in the metabolic systems involved in the transition from the fed to the fasting state or in the hormone control of these systems. In children, hypoglycemia is considered a metabolic-endocrine emergency, because it may lead to brain injury, permanent neurological sequelae and, in rare cases, death. Symptoms are nonspecific, particularly in infants and young children.

Neonatal cortical activity organizes into transient network states that are affected by vigilance states and brain injury.

Early neurodevelopment is critically dependent on the structure and dynamics of spontaneous neuronal activity; however, the natural organization of newborn cortical networks is poorly understood. Recent adult studies suggest that spontaneous cortical activity exhibits discrete network states with physiological correlates. Here, we studied newborn cortical activity during sleep using hidden Markov modeling to determine the presence of such discrete neonatal cortical states (NCS) in 107 newborn infants, with 47 of them presenting with a perinatal brain injury.

Quantitative measures of the resting EEG in stroke: a systematic review on clinical correlation and prognostic value.

Object: Quantitative electroencephalography (qEEG) has shown promising results as a predictor of clinical impairment in stroke. We systematically reviewed published papers that focus on qEEG metrics in the resting EEG of patients with mono-hemispheric stroke, to summarize current knowledge and pave the way for future research.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched the literature for papers that fitted our inclusion criteria.

EEG-Meta-Microstates: Towards a More Objective Use of Resting-State EEG Microstate Findings Across Studies.

Over the last decade, EEG resting-state microstate analysis has evolved from a niche existence to a widely used and well-accepted methodology. The rapidly increasing body of empirical findings started to yield overarching patterns of associations of biological and psychological states and traits with specific microstate classes. However, currently, this cross-referencing among apparently similar microstate classes of different studies is typically done by "eyeballing" of printed template maps by the individual authors, lacking a systematic procedure.

Do social media interventions increase vaccine uptake?

Introduction: The Italian mass COVID-19 vaccination campaign has included children aged 5-11 years as part of the target population since December 2021. One of the biggest challenges to vaccine uptake was vaccine hesitancy among parents and children's caregivers. Primary care pediatricians (PCPs), as the first point of contact between the National Health Service (NHS) and parents/caretakers, initiated various communication strategies to tackle this hesitancy.

Potential Relationship between Poor Oral Hygiene and MRONJ: An Observational Retrospective Study.

Medication-related osteonecrosis of the jaw (MRONJ) is a drug-related side effect linked but not limited to antiresorptive and antiangiogenic molecules. It recognizes several triggers in dental procedures, such as surgery, endodontic treatments, and root planing, but also prosthesis decubitus or with a spontaneous onset. Although there are many reports about the onset of this pathology, oral hygiene status is mainly described as a consequence of MRONJ.

Framing doctor-managers' resilience during Covid-19 pandemic: A descriptive analysis from the Italian NHS.

With the aim of providing evidence about doctor-managers' resilience during the Covid-19 pandemic, this study analyzes the characteristics of 114 doctor-managers operating within the Italian National Health Service (NHS). During the emergency, doctor-managers had to show adaptive capacities to deal with unexpected situations and develop new paradigms, procedures, and quick responses to patients' needs. This is in line with resilience, and in this perspective, it is crucial to investigate resilience determinants.

Ecological contexts associated with early childhood curiosity: Neighborhood safety, home and parenting quality, and socioeconomic status.

Introduction: Curiosity is an important social-emotional process underlying early learning. Our previous work found a positive association between higher curiosity and higher academic achievement at kindergarten, with a greater magnitude of benefit for children with socioeconomic disadvantage. Because characteristics of the early caregiving and physical environment impact the processes that underlie early learning, we sought to examine early environmental experiences associated with early childhood curiosity, in hopes of identifying modifiable contexts that may promote its expression.

New Biological and Chemical Evidences of Two Lamiaceae Species ( and subsp. ): In Vitro, In Silico and Ex Vivo Approaches.

In this study, the methanolic and infusion extracts of two species, and subsp. , were tested for their chemical composition and biological abilities (antioxidant, enzyme inhibitory and anti-inflammatory effects). The extracts yielded total phenolic and flavonoid contents in the range of 83.

Normalized compression distance to measure cortico-muscular synchronization.

The neuronal functional connectivity is a complex and non-stationary phenomenon creating dynamic networks synchronization determining the brain states and needed to produce tasks. Here, as a measure that quantifies the synchronization between the neuronal electrical activity of two brain regions, we used the normalized compression distance (NCD), which is the length of the compressed file constituted by the concatenated two signals, normalized by the length of the two compressed files including each single signal. To test the NCD sensitivity to physiological properties, we used NCD to measure the cortico-muscular synchronization, a well-known mechanism to control movements, in 15 healthy volunteers during a weak handgrip.

Urinary and Daily Assumption of Polyphenols and Hip-Fracture Risk: Results from the InCHIANTI Study.

A high polyphenol intake has been associated with higher bone-mineral density. In contrast, we recently demonstrated that the urinary levels of these micronutrients were associated with the long-term accelerated deterioration of the bone. To expand on the health consequences of these findings, we assessed the association between urinary level and dietary intake of polyphenols and the 9-year risk of hip fractures in the InCHIANTI study cohort.

EFFICACY OF 67% SODIUM BICARBONATE TOOTHPASTE FOR PLAQUE AND GINGIVITIS CONTROL: A SYSTEMATIC REVIEW AND META-ANALYSIS.

Objective: Previous studies demonstrated a dose-dependent efficacy of sodium bicarbonate when added to dentifrices for the mechanical control of dental biofilm. The present systematic review and meta-analysis aimed to evaluate the efficacy of a 67% sodium bicarbonate-based toothpaste for gingival health parameters improvement in subjects with gingivitis.

Materials And Methods: An electronic search on MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL), was performed using a combination of keywords, followed by a hand search on pertinent Journals.

A graph convolutional neural network for the automated detection of seizures in the neonatal EEG.

Background And Objective: Neonatal seizures are the most common clinical presentation of neurological conditions and can have adverse effects on the neurodevelopment of the neonatal brain. Visual detection of these events from continuous EEG recordings is a laborious and time-consuming task. We propose a novel algorithm for the automated detection of neonatal seizures.

Hemispheric functional segregation facilitates target detection during sustained visuospatial attention.

Visuospatial attention is strongly lateralized, with the right hemisphere commonly exhibiting stronger activation and connectivity patterns than the left hemisphere during attentive processes. However, whether such asymmetry influences inter-hemispheric information transfer and behavioral performance is not known. Here we used a region of interest (ROI) and network-based approach to determine steady-state fMRI functional connectivity (FC) in the whole cerebral cortex during a leftward/rightward covert visuospatial attention task.

EEG spectral exponent as a synthetic index for the longitudinal assessment of stroke recovery.

Objective: Quantitative Electroencephalography (qEEG) can capture changes in brain activity following stroke. qEEG metrics traditionally focus on oscillatory activity, however recent findings highlight the importance of aperiodic (power-law) structure in characterizing pathological brain states. We assessed neurophysiological alterations and recovery after mono-hemispheric stroke by means of the Spectral Exponent (SE), a metric that reflects EEG slowing and quantifies the power-law decay of the EEG Power Spectral Density (PSD).

Possible notochordal chordoma in a fossil fish from the Late Cretaceous of Lebanon.

Objective: To describe a case of an expansive endocavitary lesion at the level of the caudal tract of the vertebral column of a juvenile fish (Pycnodont) from the Late Cretaceous (Cenomanian) of Lebanon (Hjoula).

Materials: The specimen is part of the Paleontological Collection of the University Museum of Chieti, Italy, Inventory Number P #23752.

Methods: The specimen was observed macroscopically, as well as under the stereo-microscope (Leica Wild M 8); aspersion with ethanol and razing light were used to improve the observations and to take micro-photos.

Perception is associated with the brain's metabolic response to sensory stimulation.

Processing of incoming sensory stimulation triggers an increase of cerebral perfusion and blood oxygenation (neurovascular response) as well as an alteration of the metabolic neurochemical profile (neurometabolic response). Here, we show in human primary visual cortex (V1) that perceived and unperceived isoluminant chromatic flickering stimuli designed to have similar neurovascular responses as measured by blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI) have markedly different neurometabolic responses as measured by proton functional magnetic resonance spectroscopy (1H-fMRS). In particular, a significant regional buildup of lactate, an index of aerobic glycolysis, and glutamate, an index of malate-aspartate shuttle, occurred in V1 only when the flickering was perceived, without any relation with other behavioral or physiological variables.

Impaired Intracellular Ca Dynamics, M-Band and Sarcomere Fragility in Skeletal Muscles of Obscurin KO Mice.

Obscurin is a giant sarcomeric protein expressed in striated muscles known to establish several interactions with other proteins of the sarcomere, but also with proteins of the sarcoplasmic reticulum and costameres. Here, we report experiments aiming to better understand the contribution of obscurin to skeletal muscle fibers, starting with a detailed characterization of the diaphragm muscle function, which we previously reported to be the most affected muscle in obscurin () KO mice. Twitch and tetanus tension were not significantly different in the diaphragm of WT and KO mice, while the time to peak (TTP) and half relaxation time (HRT) were prolonged.
