Received cradling bias during the first year of life: A retrospective study on children with typical and atypical development
A population-level left cradling bias exists whereby 60-90% of mothers hold their infants on the left side. This left biased positioning
appears to be mutually beneficial to both the mother and the baby’s brain organization for processing of socio-emotional stimuli. Previous research connected cradling asymmetries and Autism Spectrum Disorders (ASD), entailing impairment in socio- communicative relationships and characterized by an early hypo-lateralization of brain functions. In this explorative study, we aimed to provide a contribution to the retrospective investigations by looking for early behavioral markers of neurodevelopmental disorders such as ASD. We hypothesized that an atypical trajectory in maternal cradling might be one of the possible signs of an interference in mother-infant socio-emotional communication, and thus of potential neurodevelopmental dysfunctions. To this aim, we examined photos depicting mother-child early cradling interactions by consulting family albums of 27 children later diagnosed with autism and 63 typically developing children. As regards the first half of the first year of life, no differences were shown between maternal cradling-side preferences in typical and ASD groups, both exhibiting the left-cradling bias in the 0-3 months period, but not in the 3-6 months period. However, our results show dissimilar patterns of cradling preferences during the second half of the first year of life. In particular, the absence of left-cradling shown in typical mothers was not observed in ASD mothers, who exhibited a significant left-cradling bias in the 6-12 months age group. This difference might reflect the fact that mother-infant relationship involving children later diagnosed with ASD might remain “basic” because mothers experience a lack of social activity in such children. Alternatively, it may reflect the overstimulation in which mothers try to engage infants in response to their lack of responsiveness and social initiative. However, further investigations are needed both to distinguish between these two possibilities and to define the role of early typical and reversed cradling experiences on neurodevelopment

History of mammography: analysis of breast imaging diagnostic achievements over the last century
Breast cancer is the most common forms of cancer and a leading cause of mortality in women. Early and correct diagnosis is, therefore, essential to save lives. The development of diagnostic imaging applied to the breast has been impressive in recent years and the most used diagnostic test in the world is mammography, a low-dose X-ray technique used for imaging the breast. In the first half of the 20th century, the diagnosis was in practice only clinical, with consequent diagnostic delay and an unfavorable prognosis in the short term. The rise of organized mammography screening has led to a remarkable reduction in mortality through the early detection of breast malignancies. This historical review aims to offer a complete panorama of the development of mammography and breast imaging during the last century. Through this study, we want to understand the foundations of the pillar of radiology applied to the breast through to the most modern applications such as contrast-enhanced mammography (CEM), artificial intelligence, and radiomics. Understanding the history of the development of diagnostic imaging applied to the breast can help us understand how to better direct our efforts toward an increasingly personalized and effective diagnostic approach. The ultimate goal of imaging applied to the detection of breast malignancies should be to reduce mortality from this type of disease as much as possible. With this paper, we want to provide detailed documentation of the main steps in the evolution of breast imaging for the diagnosis of breast neoplasms; we also want to open up new scenarios where the possible current and future applications of imaging are aimed at being more precise and personalized
Optimal finite-time heat engines under constrained control
This is the final version. Available on open access from the American Physical Society via the DOI in this recordWe optimize finite-time stochastic heat engines with a periodically scaled Hamiltonian under experimentally motivated constraints on the bath temperature
T and the scaling parameter λ. We present a general geometric proof that maximum-efficiency protocols for T and λ are piecewise constant, alternating between the maximum and minimum allowed values. When λ is restricted to a small range and the system is close to equilibrium at the ends of the isotherms, a similar argument shows that this protocol also maximizes output power. These results are valid for arbitrary dynamics. We illustrate them for an overdamped Brownian heat engine, which can experimentally be realized using optical tweezers with stiffness λ.China Scholarship CouncilFundational Questions InstituteCaixa FoundationGovernment of SpainFundacio CellexFundacio Mir-PuigGeneralitat de Catalunya (CERCA)Engineering and Physical Sciences Research Council (EPSRC)Royal SocietySwiss National Science FoundationHumboldt foundationCzech Science Foundatio
Thermodynamics and optimal protocols of multidimensional quadratic Brownian systems
This is the final version. Available on open access from IOP Publishing via the DOI in this recordData availability statement;
All data that support the findings of this study are included within the article (and any supplementary files).We characterize finite-time thermodynamic processes of multidimensional quadratic overdamped systems. Analytic expressions are provided for heat, work, and dissipation for any evolution of the system covariance matrix. The Bures-Wasserstein metric between covariance matrices naturally emerges as the local quantifier of dissipation. General principles of how to apply these geometric tools to identify optimal protocols are discussed. Focusing on the relevant slow-driving limit, we show how these results can be used to analyze cases in which the experimental control over the system is partial.Humboldt FoundationCzech Science Foundation'la Caixa' FoundationGovernment of SpainSevero OchoaFundacio CellexFundacio Mir-PuigGeneralitat de CatalunyaFundational Questions Institute FundEngineering and Physical Sciences Research Council (EPSRC)China Scholarship CouncilSwiss National Science Foundatio
Radiological Features of Male Breast Neoplasms: How to Improve the Management of a Rare Disease
The primary aim of our study was to assess the main mammographic and ultrasonographic features of invasive male breast malignancies. The secondary aim was to evaluate whether a specific radiological presentation would be associated with a worse receptor profile. Radiological images (mammography and/or ultrasound) of all patients who underwent surgery for male invasive breast cancer in our institution between 2008 and 2023 were retrospectively analyzed by two breast radiologists in consensus. All significant features of radiological presentation known in the literature were re-evaluated. Fifty-six patients were selected. The mean age at surgery of patients was 69 years (range: 35-81); in 82% of cases (46 patients), the histologic outcome was invasive ductal carcinoma. A total of 28 out of 56 (50%) patients had preoperative mammography; in 9/28 cases (32%), we found a mass with microcalcifications on mammography. The mass presented high density in 25 out of 28 patients (89%); the mass showed irregular margins in 15/28 (54%) cases. A total of 46 out of 56 patients had preoperative ultrasounds. The lesion showed a solid mass in 41/46 (89%) cases. In 5/46 patients (11%), the lesion was a mass with a mixed (partly liquid-partly solid) structure. We did not find any statistically significant correlation between major types of radiological presentation and tumor receptor arrangement. Knowledge of the main radiologic presentation patterns of malignant male breast neoplasm can help better manage this type of disease, which is rare but whose incidence is increasing
Increasing burden, younger age at onset and worst metabolic control in migrant than in Italian children with type 1 diabetes: an emerging problem in pediatric clinics.
To assess burden and clinical features of type 1 diabetes in migrant with respect to Italian children. Prevalent children with type 1 diabetes were identified through a multicenter study, including 46 pediatric outpatients diabetic clinics. A nested case-control study was also performed, comparing features at diabetes onset and after 1 year of insulin treatment in 84 migrants and 75 Italian children with onset in 2011, matched for age and sex. Out of 7,812 children cared for by pediatric diabetologists, 761 (10%) were migrant and 548 of them were born in Italy. Age at diagnosis was lower in migrants born in Italy (5.1 years, interquartile range (IQR) 2.2-7.7) than in those born in their original countries (7.8 years, IQR 5.3-10.3) and in Italians (9.8 years, IQR 5.9-13.0, p < 0.001). At diabetes onset, migrants had lower frequencies of positivities of markers of β-cell autoimmunity (96 vs. 99.5%, p < 0.01), higher values of weight loss (11 vs. 7%, p < 0.01), HbA1c (70 vs. 58 mmol/mol, p < 0.001), and insulin requirement (0.70 ± 0.03 vs. 0.63 ± 0.10 UI/kg/die, p = 0.05) and lower levels of 25-OH vitamin D3 (15.0 ± 2.8 vs. 20.8 ± 1.3, p = 0.03). Moreover, they experienced higher frequencies of hospitalizations during the first year of disease (19.2 vs. 2.7%, p < 0.001). Burden of type 1 diabetes in migrant children is increasing in Italy, with younger age at onset and different clinical features than in Italian children. Higher hospitalization rates and poorer glycemic control over the first year underline that approach to diabetes care in migrants needs to be improved
Cyclic Guanidines as Efficient Organocatalysts for the Synthesis of Polyurethanes
A systematic survey of basic/nucleophilic organocatalysts for the polyaddition in bulk of polyols, PEG-600, and PTMO-650, to isophorone diisocyanate (IPDI) has been performed. Guanidines were shown to be very efficient catalysts for the urethane linkage formation. Bicyclic penta-alkylated guanidines such as MTBD led to polyurethane molecular weight and dispersity that are in the range of those observed with tin-based catalysts such as DBTDL. Tetra-alkylated guanidine such as TBD was shown to be a weaker catalyst as compared to pentaalkylated guanidines, as a result of its high reactivity toward isocyanate, resulting in the formation of a less nucleophilic urea. Although the mechanism has not yet been firmly established, these experiments suggest that a nucleophilic-catalysis mechanism, involving the attack of one of the nitrogen of the guanidine onto the unsaturated system of the isocyanate, should not be totally ruled out with such strong Bronsted base catalysts
