OBJECTIVES: This retrospective study, conducted in Turin, Italy, between January 2021 and February 2023, investigates the impact of seasonal heatwaves on emergency department (ED) admissions for mental disorders. METHODS: Through the analysis of data from 2,854 patients, this research found a significant link between the occurrence of heatwaves, especially from June to August, and an elevated rate of ED admissions for psychiatric conditions. RESULTS: The data indicate a clear seasonal pattern, with admissions peaking during the hot months and diminishing in the colder months...

BACKGROUND: Hemangiomas are aberrant proliferations of blood vessels and the most frequent benign pediatric soft tissue tumors. Although they are common, genital localization is rare. This study aimed to assist doctors in the diagnosis, management, and treatment of pediatric vulvovaginal hemangiomas by conducting a review of the literature. METHODS: We conducted a literature review including papers published between August 2009 and May 2023. RESULTS: While most hemangiomas are usually indolent and resolve with time, in some cases, especially cervicovaginal and uterine ones, they might present with severe symptoms like heavy bleeding and need further instrumental investigation for diagnosis, like CT or MRI...

A case of post-neurosurgical ventriculitis caused by a KPC-producing Klebsiella pneumoniae (KPC-Kp) with a ceftazidime/avibactam-resistant, meropenem-susceptible phenotype is reported. The patient had a concomitant bloodstream infection with a wild-type KPC-Kp with a ceftazidime/avibactam-susceptible, meropenem-resistant phenotype. Prolonged treatment with intravenous fosfomycin and meropenem/vaborbactam achieved clinical success. Therapeutic drug monitoring performed during the first days of treatment showed for the first time that vaborbactam efficiently penetrates cerebrospinal fluid...

BACKGROUND: Atrial high-rate episodes (AHRE) are frequent in patients with cardiac implantable electronic devices. A decrease in device-detected P-wave amplitude may be an indicator of periods of increased risk of AHRE. OBJECTIVE: To assess the association between P-wave amplitude and AHRE incidence. METHODS: Remote monitoring data from 2,579 patients with no history of atrial fibrillation (23% pacemakers, 77% implantable cardioverter-defibrillators [ICDs] of which 40% providing cardiac resynchronization therapy [CRT]) were used to calculate the mean P-wave amplitude during 1 month after implantation...

Antipsychotic drugs (APDs) are the primary pharmacological treatment for schizophrenia, a complex disorder characterized by altered neuronal connectivity. Atypical or second-generation antipsychotics, such as Risperidone (RSP) and Clozapine (CZP) predominantly block dopaminergic D2 and serotonin receptor 2A (5-HT2A) neurotransmission. Both compounds also exhibit affinity for the 5-HT7R, with RSP acting as an antagonist and CZP as an inverse agonist. Our study aimed to determine whether RSP and CZP can influence neuronal morphology through a 5-HT7R-mediated mechanism...

The overall low-quality evidence concerning the clinical benefits of different antibiotic regimens for the treatment of infective endocarditis (IE), which has made it difficult to strongly support or reject any regimen of antibiotic therapy, has led to a discrepancy between the available guidelines and clinical practice. In this complex scenario, very recently published guidelines have attempted to fill this gap. Indeed, in recent years several antimicrobials have entered the market, including ceftobiprole, ceftaroline, and the long-acting lipoglycopeptides dalbavancin and oritavancin...

Autosomal dominant pathogenic mutations in Leucine-rich repeat kinase 2 (LRRK2) cause Parkinson's disease (PD). The most common mutation, G2019S-LRRK2, increases the kinase activity of LRRK2 causing hyper-phosphorylation of its substrates. One of these substrates, Rab10, is phosphorylated at a conserved Thr73 residue (pRab10), and is one of the most abundant LRRK2 Rab GTPases expressed in various tissues. The involvement of Rab10 in neurodegenerative disease, including both PD and Alzheimer's disease makes pinpointing the cellular and subcellular localization of Rab10 and pRab10 in the brain an important step in understanding its functional role, and how post-translational modifications could impact function...

Infectious endocarditis is a severe condition still characterized by a high morbidity and mortality rate. An early diagnosis may positively impact the outcome, so we need our diagnostic tools to match with the ever-changing epidemiologic and microbiologic landscape of infectious diseases. We read with great interest the update to the Modified Duke Criteria for the diagnosis of Infectious Endocarditis recently proposed by the International Society for Cardiovascular Infectious Diseases and decided to propose the addition of Erysipelothrix rhusiopathiae to the list of typical microorganisms causing Endocarditis...

INTRODUCTION AND AIMS: Bipolar disorder (BD) is a severe and recurring mental illness associated with a significant personal and social burden. It has been recently hypothesized that increased levels of pro-inflammatory cytokines and cortisol, which is also associated with a reduced expression of the brain-derived neurotrophic factor (BDNF), may influence affective recurrences in BD. Our study aims to: 1) assess changes in the levels of peripheral cytokines, BDNF and salivary cortisol during acute and euthymic phases of bipolar disorder, compared to that of a sample oh healthy controls; 2) evaluate whether these changes represent a biosignature for the different phases of the illness...

In the brain microRNAs (miRNAs) are believed to play a role in orchestrating synaptic plasticity at a higher-level by acting as an additional mechanism of translational regulation, alongside the mRNAs/polysome system. Despite extensive research, our understanding of the specific contribution of individual miRNA to the function of dopaminergic neurons (DAn) remains limited. By performing a dopaminergic-specific miRNA screening, we have identified miR-218 as a critical regulator of DAn activity in male and female mice...

BACKGROUND: In recent years, several interesting case reports have been published which describe the possible role of SARS-CoV-2 infection or vaccination in the etiopathogenesis of Lipschütz ulcer. Our aim is to analyze this association and provide a rapid algorithm that is of support to gynecologists and dermatologists both in the diagnosis and in setting up the therapy. To do so, in this paper, we describe an interesting case of acute vulvar ulcer triggered by SARS-CoV-2 infection and review the related literature...

In Parkinson's disease (PD), post-mortem studies in affected brain regions have demonstrated a decline in mitochondrial number and function. This combined with many studies in cell and animal models suggest that mitochondrial dysfunction is central to PD pathology. We and others have shown that the mitochondrial protein deacetylase, SIRT3 has neurorestorative effects in PD models. In this study, to determine whether there is a link between PD pathology and SIRT3, we analysed SIRT3 levels in human subjects with PD, and compared to age-matched controls...

We assessed the outcome of administration of empiric radioactive iodine (RAI) therapy to patients with differentiated thyroid cancer (DTC), in a propensity-score-matched cohort of patients with biochemical incomplete response (BIR) and without evidence of structural disease. We retrospectively evaluated 820 DTC patients without distant metastases, who underwent total thyroidectomy followed by RAI therapy, with available BIR at 12 months and follow-up evaluations. The patients were categorized according to the administration of empiric therapy (ET)...

BACKGROUND: Accurate and timely assessment of pathology specimens is critical for patient care and oncologic management. This study aimed to determine whether a standardized mastectomy diagram would facilitate communication among surgeons and pathologists and improve pathologic processing. METHODS: A prospective quality improvement study was conducted over a continuous 12-month period. During the first 6 months, usual pathologic processing of mastectomy specimens was performed per standard department protocol...

The key intermediate in the synthesis of dorzolamide, (4 S ,6 S )-methyl-5,6-dihydro-4 H -thieno[2,3- b ]thiopyran-4-ol-7,7-dioxide, can be obtained in the diastereoisomerically pure form in two straightforward steps starting from diastereoisomeric mixtures of cis / trans -(6 S )-6-methyl-5,6-dihydro-4 H -thieno[2,3- b ]thiopyran-4-yl acetate, regardless of their ratio. The reaction of crucial importance in this scheme is a remarkably stereoselective solvolysis of the acetate ester in an acetone/phosphate buffer mixture as the solvent system...
