Neocortical somatostatin neuron diversity in cognition and learning.

Somatostatin-expressing (SST) neurons are a major class of electrophysiologically and morphologically distinct inhibitory cells in the mammalian neocortex. Transcriptomic data suggest that this class can be divided into multiple subtypes that are correlated with morpho-electric properties. At the same time, availability of transgenic tools to identify and record from SST neurons in awake, behaving mice has stimulated insights about their response properties and computational function.

Long-lasting, subtype-specific regulation of somatostatin interneurons during sensory learning.

Somatostatin (SST)-expressing inhibitory neurons are a major class of neocortical γ-amino butyric acid (GABA) neurons, where morphological, electrophysiological, and transcriptomic analyses indicate more than a dozen different subtypes. However, whether this diversity is related to specific roles in cortical computations and plasticity remains unclear. Here we identify learning-dependent, subtype-specific plasticity in layer 2/3 SST neurons of the mouse somatosensory cortex.

Survival rates and extra-regional migration patterns of children and adolescents with cancer in Italy: The 30-year experience of the Italian Association of Pediatric Hematology and Oncology (AIEOP) with the Italian hospital-based registry of pediatric cancer (Mod. 1.01).

Since the 1970s, Italian pediatric oncologists have collaborated through the Italian Association for Pediatric Hematology Oncology (AIEOP) network using a common centralized system for the registration of childhood cancer, known as Model 1.01 (Mod. 1.

HEAR SCORE: A Proposal to Use Only Anamnestic and EKG Data to Evaluate Patients with Very Low Risk Chest Pain.

Purpose: Chest pain in a common symptom in patients attending Emergency Department worldwide and can be related to an extensive variety of disorders, so it represents a diagnostic and logistic challenge for Emergency physicians. The aim of this study is to identify a subgroup of patients with a low pre-test probability of major adverse cardiac events, for which there is no need of troponin testing, to avoid potential harm from false-positive testing and long length stay in ED.

Patients And Methods: We retrospectively analyzed data of patients that attended ED of Siena complaining chest pain from January 2019 to August 2021.

Quantitative Fluorescence Analysis Reveals Dendrite-Specific Thalamocortical Plasticity in L5 Pyramidal Neurons during Learning.

High-throughput anatomic data can stimulate and constrain new hypotheses about how neural circuits change in response to experience. Here, we use fluorescence-based reagents for presynaptic and postsynaptic labeling to monitor changes in thalamocortical synapses onto different compartments of layer 5 (L5) pyramidal (Pyr) neurons in somatosensory (barrel) cortex from mixed-sex mice during whisker-dependent learning (Audette et al., 2019).

Effectiveness of homologous and heterologous booster doses for an inactivated SARS-CoV-2 vaccine: a large-scale prospective cohort study.

Background: Several countries have authorised or begun using a booster vaccine dose against COVID-19. Policy makers urgently need evidence of the effectiveness of additional vaccine doses and its clinical spectrum for individuals with complete primary immunisation schedules, particularly in countries where the primary schedule used inactivated SARS-CoV-2 vaccines.

Methods: Using individual-level data, we evaluated a prospective, observational, national-level cohort of individuals (aged ≥16 years) affiliated with the Fondo Nacional de Salud insurance programme in Chile, to assess the effectiveness of CoronaVac (Sinovac Biotech), AZD1222 (Oxford-AstraZeneca), or BNT162b2 (Pfizer-BioNTech) vaccine boosters in individuals who had completed a primary immunisation schedule with CoronaVac, compared with unvaccinated individuals.

Sex differences in implicit processing of allocentric relationships between objects and location in a Simon task.

Simon tasks reveal implicit processing conflicts that arise when the abstract coding of stimulus position is incongruent with coding for location of the output response. Participants were tested with two versions of a Simon task in a counterbalanced order to examine a potential female bias for attending to object characteristics versus object location. Both tasks used a triangle pointing to the left or right.

An application of the Toronto Childhood Cancer Stage Guidelines in three population-based cancer registries: The case of central nervous tumors.

Background: Cancer stage is a determinant of survival of childhood central nervous system (CNS) cancers and could help the interpretation of survival variability among countries. Consensus guidelines to stage childhood malignancies in population cancer registries ("Toronto Childhood Cancer Stage Guidelines") have been recently proposed with the goal of data comparability. Indeed, stage is not systematically recorded in all registries and, when it is, different classification systems are used.

Evolving Services for Adolescents with Cancer in Italy: Access to Pediatric Oncology Centers and Dedicated Projects.

To describe how the provision of services for adolescents with cancer has evolved in Italy, the study evaluated access to pediatric oncology centers affiliated to the national cooperative group Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP), and the development of dedicated local projects. We calculated the observed/expected (O/E) ratio of adolescent patients (15-19 years old) admitted to AIEOP centers during the years 2013-2017. Observed cases were obtained from the AIEOP database (model 1.

Association between maternal education and survival after childhood cancer.

Background: Several nonbiological factors, including socioeconomic status indicators and other family characteristics, influence survival from childhood cancers. Our study explores the association between parental education and childhood cancer survival.

Methods: The specialized Childhood Cancer Registry of the Piedmont region in Italy provided data on all the cases (aged 0-14) diagnosed with cancer in the period 1976-2011 who resided in the city of Turin (capital of the Piedmont region) at least once since 1971.

Sex related biases for attending to object color versus object position are reflected in reaction time and accuracy.

Processing of visual features related to objects and space relations occurs within separate cortical streams that interact with selective attention. Such separation has implications for cognitive development because the perception of 'what' and 'where' provide a neural foundation for the development of aspects of higher cognition. Thus, a small attentional bias in early development for attending to one aspect over the other might influence subsequent higher cognitive processing in tasks involving object recognition and space relations.

Comment on Piscitelli et al. Hospitalizations in Pediatric and Adult Patients for All Cancer Type in Italy: The EPIKIT Study under the E.U. COHEIRS Project on Environment and Health. Int. J. Environ. Res. Public Health 2017, 14, 495.

In the "Epikit study" [1], P. Piscitelli with 27 co-authors from 20 scientific institutions estimated the absolute number of hospital admissions for newly diagnosed cancer in people aged 0-19 in Italian provinces and regions in 2007-2011.[.

Adolescents with Cancer in Italy: Improving Access to National Cooperative Pediatric Oncology Group (AIEOP) Centers.

This analysis compared the numbers of patients treated at Italian pediatric oncology group (Associazione Italiana Ematologia Oncologia Pediatrica [AIEOP]) centers with the numbers of cases predicted according to the population-based registry. It considered 32,431 patients registered in the AIEOP database (1989-2012). The ratio of observed (O) to expected (E) cases was 0.

The economic burden of caregiving on families of children and adolescents with cancer: a population-based assessment.

Background: Childhood cancer represents a relevant economic burden on families. The preferred tool to investigate family expenditure is the retrospective questionnaire, which is subject to recall errors and selection bias. Therefore, in the present study the economic burden of caregiving on families of children and adolescents (0-19 years of age) with cancer was analysed using administrative data as an alternative to retrospective questionnaires.

Life after childhood cancer: marriage and offspring in adult long-term survivors--a population-based study in the Piedmont region, Italy.

The majority of childhood cancer cases survive to adulthood. We describe the experience of marriage and reproduction as indicators of quality of life, in a population-based cohort of adult long-term survivors after early cancer reported to the Childhood Cancer Registry of Piedmont. The study included 1237 survivors with a malignant neoplasm diagnosed during 1967-2000 when aged 0-14 years, who attained age 18 years.

Extracranial and intracranial vertebral artery dissection: long-term clinical and duplex sonographic follow-up.

Purpose: To determine the value of color Doppler sonography (CDUS) in the diagnosis and follow-up of patients with extracranial and intracranial vertebral artery (VA) dissection.

Method: Thirty-three patients aged 42 +/- 12 years with 40 VADS confirmed via digital subtraction angiography (DSA) (n = 37) and magnetic resonance angiography (MRA) (n = 3) were included in the study. All patients were investigated with extracranial CDUS and transcranial CDUS (TCCDUS) over a mean +/- SD follow-up period of 42 +/- 24 months and occurrence of new ischemic symptoms was assessed.

Absence of gravity-dependent modulation of straight sinus flow velocity in healthy humans.

The influence of whole-body positions on the cerebral blood flow in normal subjects is unclear. Blood flow in cerebral veins and sinuses is continuous, pulsatile and proportional to cerebral blood flow. We examined young healthy volunteers to evaluate peak mean flow velocity (vm) in the straight sinus (SS) assessed by transcranial Doppler sonography in predefined variations of the whole-body pitch position relative to gravity in the presence of a normal (normocarbia) and an impaired (hypercarbia) cerebral autoregulation.

Analysis of nonresponse in the assessment of health-related quality of life of childhood cancer survivors.

The aim of this study was to compare the characteristics of respondents and nonrespondents in a survey of childhood cancer survivors recorded in the Childhood Cancer Registry of Piedmont and their current primary care general practitioners. Eligible subjects were identified from the Childhood Cancer Registry of Piedmont and the referring general practitioners were traced through the National Health Service. A postal questionnaire was sent both to childhood cancer survivors and to their general practitioners.

Avoided deaths as an indicator of improvement of childhood cancer treatment.

The aim of this study was to estimate how many deaths have been avoided because of the substantial improvement in childhood cancer survival both in Piedmont (2769 incident cases) and in Italy during 1970-1999. For each time period of diagnosis, the number of avoided deaths within 5 years after diagnosis was estimated as the difference between the observed number of deaths and the number of deaths that would have been observed if the patients had experienced the same mortality as in the reference period of 1970-1974. The national estimate of the number of avoided deaths was calculated by applying Piedmont cumulative mortality to the expected number of incident cases in Italy.

Mortality from cancer and other causes in parents of children with cancer: a population-based study in Piedmont, Italy.

This population-based study (the largest on this issue conducted in Southern Europe) has examined mortality among the parents of 2622 children diagnosed with cancer in Piedmont during 1967-1994. Parents were followed up from the date of the index child's birth until the end of 2000, yielding a total of 118 090.7 person-years of observation.

Health-related quality of life of long-term childhood cancer survivors: a population-based study from the Childhood Cancer Registry of Piedmont, Italy.

Aim Of The Study: To determine the Health Related Quality of Life (HRQL) in a population-based cohort of long-term survivors of childhood cancer in Piedmont, northwestern Italy.

Patients And Methods: During 2003, a 15-item Health Utilities Index questionnaire was mailed to 1005 5-year survivors, identified from the population-based Childhood Cancer Registry of Piedmont, to derive scores for overall HRQL and for eight single attributes of health. Score differences were estimated as adjusted prevalence odds ratios.
