Tracking cryptic SARS-CoV-2 hospital outbreak through quasispecies analysis.

Background: Since the beginning of the pandemic, contact tracing has been one of the most relevant issues to understand SARS-CoV-2 transmission dynamics and, in this context, the analysis of quasispecies may turn out to be a useful tool for outbreak investigations. Analysis of the intra-host single nucleotide variants (iSNVs) found in the nsp2, ORF3, and ORF7 genes of SARS-CoV-2 was conducted in order to correctly identify virus transmission chain among patients hospitalized in Brescia Civic Hospital.

Methods: During the period between August and October 2023, 13 nasopharyngeal specimens, collected from patients admitted to Brescia Civic Hospital, were tested for SARS-CoV-2 positivity and molecularly characterized.

Is it still autism? The increasing broadening of the autism spectrum.

Clinical significance of a broad autism phenotype (BAP) seems to be increasingly supported by growing reports of high prevalence of subthreshold autism spectrum disorder (sASD) or autistic traits (AT) in various demographic samples, particularly in individuals with psychiatric conditions. We question this increasing extension of the autism spectrum and its potential negative consequences for clinical services, research, cultural attitudes, and resource allocation, as well as alternative explanations of what is currently attributed to sASD and AT. In modern psychiatry the diagnostic threshold is paramount and associated with a significant impairment of functioning, implying that symptom specificity is more relevant than sensitivity.

Identification of Specific microRNAs in Adipose Tissue Affected by Lipedema.

Lipedema is a chronic disorder affecting women with a 10% incidence worldwide. It is often confused with obesity. This study was undertaken to study microRNAs in lipedema tissue assessed by direct hybridization using the robust n-counter flex DX CE-IVD platform.

Eating and feeding disorders in adults with intellectual developmental disorder with and without autism spectrum disorder.

Background: The present observational cross-sectional study aimed at investigating the prevalence of feeding and eating disorders (FEEDs) in adults with intellectual disability (ID)/intellectual developmental disorder (IDD) with or without autism spectrum disorder (ASD) and specific problem behaviours (PBs).

Methods: Two hundred six adults with ID/IDD consecutively attending residential and rehabilitative facilities, 59.2% of which had co-occurring ASD, were assessed for presence of FEEDs by a structured interview specifically developed for the study and Diagnostic Manual - Intellectual Disability criteria.

Autism and psychopathology - prevalence, identification, and symptoms equivalence: study protocol.

Objective: Despite increasing evidence of high psychopathological vulnerability in people with Autism Spectrum Disorder (ASD) and/or Intellectual disability (ID), comprehensive data on prevalence and presentation of psychiatric disorders (PD) in people with significant cognitive and communication impairment are lacking. The extent to which PD can present with behavioral/observable symptoms and include Problem Behaviors (PB) has also been scarcely evaluated through population-based studies. The paper presents the protocol of a cross-sectional study aimed at filling these gaps, referred to a large multicentric Italian population-based sample of adolescents and adults.
