School engagement, school climate and youth externalizing behaviors: direct and indirect effects of parenting practices.

This research aimed to explore the direct and indirect effects of students' school engagement, school climate and parenting practices on youth's externalizing behaviors. A quantitative methodology with a sample of 183 Portuguese students, aged between 11 and 16 years old, was used. The main results suggested negative associations between externalizing behaviors and higher levels of school engagement and positive school climate.

"ZARPAR"-Educational Program for Cognitive and Behavioral Development: Results of an Experiment to Evaluate Its Impact on Antisocial and Pro-Social Behavior.

Using an experimental design and a multi-measure and multi-informant approach, the current study sought to evaluate the impact of the early developmental prevention program "ZARPAR"-an intervention designed as a social and cognitive skills training program, that seeks to promote children's behavioral adjustment. A sample of elementary school children (experimental group  = 37; control group  = 66), attending Portuguese schools, was assessed before and 6 months after the intervention on the program's key-dimensions: behavioral problems, social skills, and executive functioning. Based on parent and teacher reports, the results largely suggested that the intervention had no effect or, for some dimensions, even the existence of negative outcomes.

Development and Investigation of PEDOT:PSS Composition Coated Fabrics Intended for Microwave Shielding and Absorption.

This study presents the investigation of the electromagnetic properties and resistance performance of electrically conductive fabrics coated with composition containing the conjugated polymer system poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT:PSS). The developed fabrics were intended for electromagnetic radiation (EMR) shielding in microwave range and for absorbing microwaves in radar operating range, so as to act as radar absorbing materials (RAM). The measurements of reflection and transmission of the developed fabrics were performed in a frequency range of 2-18 GHz, which covers the defined frequencies relevant to the application.

The new SARS-CoV-2 pandemic is an example of an international public health emergency, which is associated with considerable social and economic challenges. At the healthcare level there is the risk that nosocomial outbreaks can be local amplifiers. Adequate infection control practices are of critical importance, which include proper use of personal protective equipment.

Multiplex sequencing for EZH2, CD79B, and MYD88 mutations using archival cytospin preparations from B-cell non-Hodgkin lymphoma aspirates previously tested for MYC rearrangement and IGH/BCL2 translocation.

Background: Gene rearrangements and specific translocations define some B-cell non-Hodgkin lymphoma (NHL) subtypes. Genome-wide mutational studies have revealed recurrent point mutations with prognostic implications. The goals of this study were to evaluate the feasibility of applying a multiplex mutation assay to archival cytospin preparations (CPs) and to investigate the rate of EZH2, CD79B, and MYD88 mutations in B-cell NHL samples previously tested for MYC rearrangement and/or IGH/BCL-2 translocation.

Human papilloma virus genome is rare in North American non-small cell lung carcinoma patients.

The reported prevalence for presence of human papillomavirus (HPV) genome in lung cancer varies across the world, and limited data are available for North America. P16 immunostaining is used as a surrogate marker for the presence of HPV in cervical and head and neck cancers. In non-small cell lung carcinoma (NSCLC), the association between P16 protein overexpression and HPV remains unclear.

FISH assay development for the detection of p16/CDKN2A deletion in malignant pleural mesothelioma.

Aims: To develop a fluorescence in-situ hybridisation (FISH) assay for detecting p16/CDKN2A deletion on paraffin tissue sections for use as an ancillary test to distinguish reactive from malignant mesothelial proliferations.

Method: Dual-colour FISH for p16/CDKN2A and chromosome 9 (CEP-9) was performed on 11 benign mesothelial proliferations and 54 malignant pleural mesothelioma (MPM) cases to establish cut-off values for p16/CDKN2A deletion. A third MYC probe was used to verify cases showing homozygous deletion.

The role of fine-needle aspiration in the diagnosis of thyroid lymphoma: a retrospective study of nine cases and review of published series.

Aims: To review the clinicopathological, cytomorphological and immunophenotyping data from new cases and published series of thyroid lymphoma diagnosed by fine-needle aspiration (FNA), in order to identify useful diagnostic features.

Methods: Cases from 1988 to 2009 with an FNA diagnosis of thyroid lymphoma were selected from hospital records. An electronic MEDLINE and EMBASE search retrieved published series from 1980 to 2009.

Penile metastasis of urothelial carcinoma diagnosed by fine-needle aspiration.

Penile neoplasms are rare and can be primary or represent metastasis or local recurrence. The most common primary cancer of the penis is squamous cell carcinoma, accounting for 95% of all cancers. In spite of the rich vascularity of the organ, penile metastases are uncommon.

The association of p16(INK4A) and fragile histidine triad gene expression and cervical lesions.

Objective: This cross-sectional study was intended to assess the association between immunohistochemical analysis of p16 and fragile histidine triad (FHIT) and the presence of precancerous cervical lesions.

Materials And Methods: Women seen at Pérola Byington Hospital, São Paulo, Brazil, with histologically confirmed cervicitis (n = 31), cervical intraepithelial neoplasia (CIN) 1 (n = 30), CIN 2,3 (n = 30), and cervical cancer (n = 7) had also cervical material collected for liquid-based cytology, human papillomavirus Hybrid Capture 2 (HC2) test, and p16 and FHIT immunohistochemical reactions.

Results: p16 and FHIT reactions were scored as the following: <1%, 1% to 5%, >5% to 25%, and >25%.

Comparison between endoscopic brush cytology performed before and after biliary stricture dilation for cancer detection.

Background: Confirmation of malignancy within biliary strictures is endoscopically challenging. Dilation of strictures has been reported to enhance cytological diagnosis.

Aim: To compare brush cytology results before and after biliary stricture dilation.

Fine-needle aspiration cytology in the diagnosis of superficial lymphadenopathy: a 5-year Brazilian experience.

To determine the accuracy of fine-needle aspiration (FNA) in the diagnostic assessment of lymphadenopathies, a retrospective study was conducted on 627 cases of FNA of the lymph nodes performed at Department of Pathology, UNIFESP (Federal University of São Paulo), between 1997 and 2001. Cytology results were compared to the results of biopsies if available. The cytological diagnosis was unsatisfactory in 14.

Immunocytochemical expression of p16INK4A and Ki-67 in cytologically negative and equivocal pap smears positive for oncogenic human papillomavirus.

This study was designed to analyze the cross-sectional comparison of the p16 and Ki-67 immunocytochemical expression in negative and equivocal (atypical squamous cells of undetermined significance (ASC-US)) liquid-based cytology (LBC) samples testing positive for high-risk human papillomavirus (HPV) types with HC2 assay or polymerase-chain reaction (PCR). A series of 199 consecutive LBC specimens derived from the same number of women participating in the ongoing Latin American Screening Study at Leonor Mendes de Barros Hospital, Sao Paulo, were analyzed using immunocytochemistry for expression of p16 and Ki-67 in negative and equivocal LBC samples testing positive for high-risk HPV types with hybrid capture II test (HC2) or PCR. All patients with at least one test positive (cytology, PCR, and/or HC2) were followed each 6 months for 3 years.

[Survival of patients with malignant biliary stricture based on endoscopic brushing and on bilirubinemia].

Background: Pancreatic cancer and cholangiocarcinoma are the main causes of malignant biliary stricture. Both types of cancers have dismal survival rates, and treatment has little or no effect on prolonging the patients lives. Prognostic definition at initial endoscopic retrograde cholangiopancreatography is important to choose the most suitable management.
