Teachers' perceptions of their students' academic skills can affect students' achievement and may be influenced by unrelated student characteristics such as socioeconomic status (SES). In this ad hoc randomized controlled trial, teachers (n = 28) were randomly assigned to receive training on using assessment to guide literacy instruction, Assessment-to-Instruction (A2i), or on Math PALS (control). Teachers rated students' (n = 446) academic competence. A2i teachers' ratings did not vary by SES, and their ratings correlated more strongly with students' literacy and mathematics assessment scores compared with those of the control teachers. Control teachers generally underestimated lower SES students' academic competence; underestimation was greater at more affluent schools. Teachers' ratings of students' academic competence predicted reading and mathematics outcomes. Thoughtful use of assessments to guide instruction appeared to improve the precision of teachers' ratings of students' academic competence, improve student outcomes, and reduce potential teacher biases about children from higher-poverty families.Quantitative phase imaging (QPI) is a valuable label-free modality that has gained significant interest due to its wide potentials, from basic biology to clinical applications. Most existing QPI systems measure microscopic objects via interferometry or nonlinear iterative phase reconstructions from intensity measurements. However, all imaging systems compromise spatial resolution for the field of view and vice versa, i.e., suffer from a limited space bandwidth product. Current solutions to this problem involve computational phase retrieval algorithms, which are time-consuming and often suffer from convergence problems. In this article, we presented synthetic aperture interference light (SAIL) microscopy as a solution for high-resolution, wide field of view QPI. The proposed approach employs low-coherence interferometry to directly measure the optical phase delay under different illumination angles and produces large space-bandwidth product label-free imaging. find more We validate the performance of SAIL on standard samples and illustrate the biomedical applications on various specimens pathology slides, entire insects, and dynamic live cells in large cultures. The reconstructed images have a synthetic numeric aperture of 0.45 and a field of view of 2.6 × 2.6 mm2. Due to its direct measurement of the phase information, SAIL microscopy does not require long computational time, eliminates data redundancy, and always converges.The Streptomyces sp. VKM Ac-2618D strain has been identified, and its morphological and physiological features have been studied in relation to the production of the immunosuppressant tacrolimus. The phenotypic variability of the strain was analyzed, and a dissociant with a high level of tacrolimus production was selected. Based on a comprehensive study of morphological, physiological, and chemotaxonomic properties and on phylogenetic analysis, the strain was named Streptomyces tsukubensis VKM Ac-2618D. The strain genome contains the full version of the tacrolimus biosynthetic gene cluster. The advantages of fed-batch cultivation mode for tacrolimus biosynthesis are shown. The results broaden the understanding of the characteristics of polyketide biosynthesis and can be used in the development of technology for tacrolimus production.Real-time reverse-transcription polymerase chain reaction (RT-PCR) is currently the most popular method for early COVID-19 diagnostics. However, loop-mediated isothermal amplification (LAMP) is superior to real-time RT-PCR in rapidity and simplicity, since it does not require expensive laboratory equipment and trained personnel. LAMP-based diagnostic kits for COVID-19 testing already exist, but corresponding tests are not yet widely available. The method has great potential for mass application. Here, we discuss the technical and methodological aspects of its widespread adoption.The vertices of two specific eigenvectors, obtained from a novel linear eigenvalue problem, describe two curves on the surface of an N-dimensional unit hypersphere. N denotes the number of degrees of freedom in the framework of structural analysis by the Finite Element Method. The radii of curvature of these two curves are 0 and 1. They correlate with pure stretching and pure bending, respectively, of structures. The two coefficient matrices of the eigenvalue problem are the tangent stiffness matrix at the load level considered and the one at the onset of loading. The goals of this paper are to report on the numerical verification of the aforesaid geometric-mechanical synergism and to summarize current attempts of its extension to combinations of stretching and bending of structures.
This study developed and validated three questionnaires addressed to the accrediting bodies of the CME system, the providers and the end-users to investigate facilitating factors, barriers and achieved results. Facilitating factors, barriers and achieved results were then described, and the predictors of the achieved result were identified.

Multiphase and multi-method study.

The developed questionnaires show evidence of validity and reliability. 8098 healthcare professionals, 10 accrediting bodies and 206 providers were enrolled to the study. The facilitating factors show the greater predictive capacity in explaining the variance of the perceptions of achieved results in all three groups.

The common perspectives of the participants guided the creating of a framework aimed to provide guidance for strengthening facilitating factors regarding the activities of accrediting bodies, providers, and end-users of CME education.

During the SARS-CoV-2 pandemic, this device proved useful in emergency medical service for the early assessment of respiratory distress, allowing the appropriate care level to be determined for each patient. 25 cases of covid-19 positive patients in the province of Arezzo were analyzed; POCT blood gas analysis made it possible to evaluate and treat at home about half of the patients (52%) and to admit the others directly to the most appropriate ward. However, some critical issues were found; the limited sample size suggest further research to assess the actual impact of this technology.Mutational oncology is becoming a fundamental element of diagnostic-therapeutic care pathways and requires new organizational models that allow for the aggregation of administrative, clinical and biomolecular data. From the experience of the Periplo Foundation in measuring the diagnostic and therapeutic care pathways (DTCP) indicators of almost 20 thousand women with breast cancer in five Italian regions, which showed the difficulty of measuring the efficiency of diagnostic-therapeutic care pathways based on the data available in the existing databases, the Foundation hopes for the creation of digital environments built with the aim of showing the greater/lesser efficiency of the health system.From "one-size-fits-all medicine" to stratified and precision medicine, to network oncology the paradigm shift in therapeutic approaches in oncology is requiring new care and governance models. Molecular tumor board, network analysis, real-world evidence only through new tools that do not reduce the complexity of the challenges will it be possible to introduce innovation into the healthcare system.The transition from the traditional to the mutational model in oncology represents a crucial change, not only from the nosological point of view, since - unlike the traditional one - the new approach is no longer strictly linked to anatomical localization and histology, but also from the point of view of adaptation of the health and regulatory systems to the new paradigm. Agnostic oncology therefore represents a challenge for the evolution of the entire path of the drug, not only for its clinical development, but also concerning the diagnostic-therapeutic and regulatory approach to be followed for the authorization and evaluation of these drugs.In the oncology, the construction, implementation and evaluation of the care pathway must consider the integration of the "histological approach" with the "mutational" one, focused on the identification of specific molecular alterations to which the so-called "agnostic drugs" are targeted. To investigate this issue, a specific Working Group of the MaCroScopio Project (observatory on chronicity) was held in which the leading Italian experts in the oncology and regulatory field participated. From their articles, collected in this dossier, it clearly emerges the need of appropriate tools to manage the intrinsic complexity of the new mutational model and the challenges posed by agnostic drugs; among these Molecular Tumor Board, care pathway and Real-World Data. All this, to promote, for new oncological drugs, the transition from the classic study of the "place in therapy" to the "place in pathway", aimed to build the clinical, regulatory and institutional bases on which mutational oncology is based and make it a reality for all patients who need it.
In Italy, the monoclonal antibodies nivolumab and pembrolizumab are subjected to the AIFA monitoring registries for the indication "advanced melanoma (unresectable or metastatic) in adults". These two drugs have the same eligibility criteria, and they are indicated until failure due to progression or toxicity; both of these drugs have also undergone dosage changes from pro/kg to flat dose. In this observational study, also based on clinical eligibility parameters, we wanted to investigate the rwTTD, definitive and temporary suspensions, as well as dose modifications.

We enrolled patients who started a treatment with nivolumab or pembrolizumab and were admitted to the Regina Elena National Cancer Institute in the period between 01/01/2016 and 31/12/2018. Treatments were followed up to 31/01/2021. Data were collected from the AIFA monitoring registries and from local therapy monitoring databases. We used the Kaplan-Meier method to estimate rwTTD, and the differences between sample subgroups were evaluated uhat it is therefore important to manage toxicities and then resume treatment, whenever possible. In patients who switched to a flat dose, there was an evident increase in the dose administered, especially for pembrolizumab.
Patients who temporarily stopped the treatment had a median rwTTD that is three times higher than patients who stopped permanently and had at least 45 days of therapy. Other studies suggest that patients who had immunological response and side effects, then had better PFS and OS than those without side effects. It is confirmed that it is therefore important to manage toxicities and then resume treatment, whenever possible. In patients who switched to a flat dose, there was an evident increase in the dose administered, especially for pembrolizumab.
