ABSTRACT

O presente texto tem o objetivo de explanar ações desempenhadas por psicólogas(os) trabalhadoras(es) dos Centros de Referência Especializados de Assistência Social (Creas), em situações de violência intrafamiliar, identificadas a partir do estude empírico realizado por mim, psicóloga pesquisadora, também trabalhadora de um Creas. Participaram da pesquisa doze psicólogas(os), trabalhadoras(es) destes centros, em sete municípios do interior do Rio Grande do Sul, onde foram realizadas, presencialmente, as entrevistas. A análise dos dados apontou para uma compreensão metodológica a partir de três dimensões já apontadas na bibliografia, sendo elas: a) Acolhida Inicial, que demonstra que esses profissionais geralmente iniciam suas práticas com uma família ou indivíduo indo ao encontro destes, buscando a vinculação dos mesmos com o serviço; b) Acompanhamento Especializado, onde essas(es) trabalhadoras(es) desenvolvem suas práticas com diversidade e criatividade, a partir de visitas domiciliares, trabalhos com grupos, indivíduos ou famílias, geralmente em conjunto com outros profissionais, principalmente assistentes sociais; c) Articulação com a Rede, onde se identificou um importante movimento para o trabalho em conjunto com outros serviços disponíveis no território. Por fim, as considerações finais indicam que ainda há um caminho a ser trilhado com relação à definição das práticas dos psicólogos no Creas. Porém, há muito que se falar a respeito de práticas que já estão ocorrendo. Assim, tornam-se relevantes as pesquisas acadêmicas nesse contexto, pois ao inserir os profissionais psicólogos trabalhadores da política, eles podem promover uma articulação entre a produção do fazer cotidiano e a reflexão teórica e acadêmica sustentada pelas pesquisas.(AU)


This study aims to explore the activities developed by psychologists from the Centros de Referência de Atenção Especializada (CREAS - Brazilian Specialized Social Assistance Reference Centers), regarding situations of intrafamily violence identified by me, the author, a research psychologist and, CREAS worker. Participants include 12 psychologists who work on such centers from 7 cities in the countryside of Rio Grande do Sul, Brazil, where the interviews were conducted in person. The data analysis pointed toward a methodological comprehension based on 3 dimensions that have already been mentioned in the literature: the Initial Approach, which shows that these workers usually initiate their practices with a family or an individual by going after them, seeking bond development with the service. The Specialized Follow-up, in which these workers develop their practices with diversity and creativity, through home visits and activities with group, family or individual, often with other workers, such as social assistance workers. And the Network Articulation, in which a significant movement toward working with the public services available on each territory is identified. Finally, there is still a path to be taken regarding the definition of psychological practices on CREAS, however, there is much to be noticed of what has already been occurring. Thus, academic research on such context is relevant since the inclusion of psychologists who work in this policy may promote an articulation between daily activity and the theoretical and academic reflection, supported by the research.(AU)


Este texto tuvo por objetivo explicar las acciones desarrolladas por psicólogas/os trabajadoras/es en los "Centros de Referência Especializados de Assistência Social" (CREAS) (Centros de Referencia Especializados en Asistencia Social), respecto a las situaciones de violencia intrafamiliar, identificadas por un estudio empírico hecho por una psicóloga-investigadora que actúa en un CREAS. Participaron 12 psicólogas/os que trabajan en estos centros, en siete ciudades del interior de Rio Grande do Sul (Brasil), donde se llevó a cabo las entrevistas en persona. El análisis de datos apuntó a una comprensión metodológica de tres dimensiones ya destacadas en la bibliografía: la Acogida Inicial, que enseña que estos profesionales generalmente empiezan sus prácticas con una familia o individuo buscando el encuentro para la promoción de la vinculación con el servicio; El Seguimiento Especializado, en el que desarrollan sus prácticas con diversidad y creatividad desde visitas domiciliarias, trabajos con grupos, individuos o familias, generalmente junto a otros profesionales, sobre todo con trabajadores sociales; y Articulación con la Red de Servicios, en la cual se identificó un importante movimiento para el trabajo con otros servicios disponibles en el territorio. Por fin, se observa que todavía hay un camino por recorrer en relación a la definición de las prácticas de psicólogos en CREAS, aunque hay mucho que decir respecto a las prácticas que ya están ocurriendo. Así, se vuelven relevantes las investigaciones académicas en ese contexto por introducir a los profesionales psicólogos trabajadores de la política, las cuales pueden promover una articulación entre la producción del hacer cotidiano y la reflexión teórica y académica sustentada por las investigaciones.(AU)

ABSTRACT

A utilização de procedimentos estatísticos é de fundamental importância para a interpretação apropriada de um conjunto de dados. Desta forma, a baixa aderência do teste aos dados selecionados pode levar a conclusões inadequadas. Portanto, a escolha do teste paramétrico e não paramétrico para dados pareados deve levar em conta a normalidade dos dados. Com isso, aplicar o coeficiente de correlação de Pearson (teste paramétrico) em dados não paramétricos aumenta as chances de associações espúrias (por acaso ou erro sistemático), as quais resultam em erro do Tipo I. Entendendo que as vezes o pensamento do jovem pesquisador e também de editores de periódicos científicos serão guiados por resultados positivos. É comum a possibilidade de editores selecionarem artigos para publicação tendo como base o valor de p <0,05. Contudo, também seria importante selecionar os artigos levando em consideração os cumprimentos dos pressupostos para a utilização de testes paramétricos e não-paramétricos. Com isso, objetivo do presente estudo foi abordar os dois testes de coeficiente de correlação de Pearson e Spearman e sugerir recomendações para praticantes de estatística na área de Ciências da Saúde para a utilização segura e adequada dos dados antes da publicação.(AU)


The use of statistical procedures is of fundamental importance for the proper interpretation of data analysis. In this way, the low adherence of the test to the selected data can lead to inadequate conclusions. Therefore, the choice of parametric and non-parametric tests for paired data should take into account the normality of the data. Therefore, applying the Pearson correlation coefficient (non-parametric test) in non-parametric data increases the chances of spurious associations (by chance or systematic error), which result in a Type I error. Knowing that young researcher and editors of scientific journals might be guided by positive results. It is common for editors to select articles for publication based on p < 0.05 value. However, it would also be important to select papers taking into account the fulfillment of the assumptions for the use of parametric and non-parametric tests. Thus, the aim of the present study was to address the two Pearson and Spearman correlation coefficient tests and to suggest recommendations for practitioners of statistics in the area of Health Sciences for the safe and adequate use of data prior publication.(AU)

ABSTRACT

PURPOSE: We determined whether elevated serum alkaline phosphatase (ALP) was related to prevalence, location, type, length, and recurrence of pterygium in a population from the Republic of Korea.METHODS: A nationwide cross-sectional dataset, the Korean National Health and Nutrition Examination Survey (2008–2011), was used in this study. All participants were > 30 years of age and underwent the ALP test and ophthalmic evaluation (n = 22,359). One-way analysis of variance, the chi-square test, and Fisher's exact test were used to compare characteristics and outcomes among participants. Multivariable logistic regression was used to examine the possible associations between serum ALP levels and various types of pterygium. Data were adjusted for known risk factors for development of pterygium and ALP elevation (age, sex, residence, sunlight exposure, drinking, smoking, hypertension, diabetes, BMI, AST, ALT, vitamin D, and HDL).RESULTS: The overall prevalence of pterygium was 8.1%, and participants with pterygium had higher levels of serum ALP (p < 0.001). Participants with higher serum ALP had a significantly higher prevalence of all types of pterygium than those in the lower serum ALP quartiles. After adjusting for potential confounding factors, multivariate logistic regression analysis revealed that ALP was associated with the prevalence of pterygium (odds ratio [OR], 1.001; p = 0.038). Trend analysis between the OR and ALP quartiles revealed a linear trend in overall prevalence and in the intermediate type of pterygium. Subgroup analysis revealed a stronger correlation in participants > 50 years of age. One-way analysis of variance revealed an association between the size of pterygium and serum ALP quartile levels. Serum ALP was not associated with recurrence of pterygium.CONCLUSIONS: Increased serum ALP was associated with the prevalence and size of pterygium.

ABSTRACT

Post-transcriptional regulations of mRNA transcripts such as alternative splicing and alternative polyadenylation can affect the expression of genes without changing the transcript levels. Recent studies have demonstrated that these post-transcriptional events can have significant physiological impacts on various biological systems and play important roles in the pathogenesis of a number of diseases, including cancers. Nevertheless, how cellular signaling pathways control these post-transcriptional processes in cells are not very well explored in the field yet. The mammalian target of rapamycin complex 1 (mTORC1) pathway plays a key role in sensing cellular nutrient and energy status and regulating the proliferation and growth of cells by controlling various anabolic and catabolic processes. Dysregulation of mTORC1 pathway can tip the metabolic balance of cells and is associated with a number of pathological conditions, including various types of cancers, diabetes, and cardiovascular diseases. Numerous reports have shown that mTORC1 controls its downstream pathways through translational and/or transcriptional regulation of the expression of key downstream effectors. And, recent studies have also shown that mTORC1 can control downstream pathways via post-transcriptional regulations. In this review, we will discuss the roles of post-transcriptional processes in gene expression regulations and how mTORC1-mediated post-transcriptional regulations contribute to cellular physiological changes. We highlight post-transcriptional regulation as an additional layer of gene expression control by mTORC1 to steer cellular biology. These emphasize the importance of studying post-transcriptional events in transcriptome datasets for gaining a fuller understanding of gene expression regulations in the biological systems of interest.

ABSTRACT

OBJECTIVE: To investigate pathologic discrepancies between colposcopy-directed biopsy (CDB) of the cervix and loop electrosurgical excision procedure (LEEP) in women with cytologic high-grade squamous intraepithelial lesions (HSILs).METHODS: We retrospectively identified 297 patients who underwent both CDB and LEEP for HSILs in cervical cytology between 2015 and 2018, and compared their pathologic results. Considering the LEEP to be the gold standard, we evaluated the diagnostic performance of CDB for identifying cervical intraepithelial neoplasia (CIN) grades 2 and 3, adenocarcinoma in situ, and cancer (HSIL+). We also performed age subgroup analyses.RESULTS: Among the study population, 90.9% (270/297) had pathologic HSIL+ using the LEEP. The diagnostic performance of CDB for identifying HSIL+ was as follows: sensitivity, 87.8%; specificity, 59.3%; balanced accuracy, 73.6%; positive predictive value, 95.6%; and negative predictive value, 32.7%. Thirty-three false negative cases of CDB included CIN2,3 (n=29) and cervical cancer (n=4). The pathologic HSIL+ rate in patients with HSIL− by CDB was 67.3% (33/49). CDB exhibited a significant difference in the diagnosis of HSIL+ compared to LEEP in all patients (p<0.001). In age subgroup analyses, age groups <35 years and 35–50 years showed good agreement with the entire data set (p=0.496 and p=0.406, respectively), while age group ≥50 years did not (p=0.036).CONCLUSION: A significant pathologic discrepancy was observed between CDB and LEEP results in women with cytologic HSILs. The diagnostic inaccuracy of CDB increased in those ≥50 years of age.

ABSTRACT

BACKGROUND: Atopic dermatitis (AD) is recognized as a common inflammatory skin disease and frequently occurred in Asian and Black individuals.OBJECTIVE: Since the limitation of dataset associated with human severe AD, this study aimed to screen potential novel biomarkers involved in mild AD.METHODS: Expression profile data (GSE75890) were obtained from the database of Gene Expression Omnibus. Using limma package, the differentially expressed genes (DEGs) between samples from AD and healthy control were selected. Furthermore, function analysis was conducted. Meanwhile, the protein-protein interaction (PPI) network and transcription factor (TF)-miRNA-target regulatory network were constructed. And quantitative real-time polymerase chain reaction (qRT-PCR) was used to validate the expressions patterns of key genes.RESULTS: In total, 285 DEGs including 214 upregulated and 71 downregulated genes were identified between samples from two groups. The upregulated DEGs were mainly involved in nine pathways, such as hematopoietic cell lineage, pertussis, p53 signaling pathway, staphylococcus aureus infection, and cell cycle, while tight junction was the only pathway enriched by the downregulated DEGs. Cyclin B (CCNB)1, CCNB2, cyclin A (CCNA)2, C-X-C motif chemokine ligand (CXCL)10, and CXCL9 were key nodes in PPI network. The TF-miRNA-target gene regulatory network focused on miRNAs such as miR-106b, miR-106a, and miR-17, TFs such as nuclear factor kappa B subunit 1, RELA proto-oncogene, Sp1 transcription factor, and genes such as matrix metallopeptidase 9, peroxisome proliferator activated receptor gamma , and serpin family E member 1. Moreover, the upregulation of these genes, including CCNB1, CCNB2, CCNA2, CXCL10, and CXCL9 were confirmed by qRT-PCR.CONCLUSION: CCNB1, CCNB2, CCNA2, and CXCL9 might be novel markers of mild AD. miR-106b and miR-17 may involve in regulation of immune response in AD patients.

ABSTRACT

Although microscopic analysis of tissue slides has been the basis for disease diagnosis for decades, intra- and inter-observer variabilities remain issues to be resolved. The recent introduction of digital scanners has allowed for using deep learning in the analysis of tissue images because many whole slide images (WSIs) are accessible to researchers. In the present study, we investigated the possibility of a deep learning-based, fully automated, computer-aided diagnosis system with WSIs from a stomach adenocarcinoma dataset. Three different convolutional neural network architectures were tested to determine the better architecture for tissue classifier. Each network was trained to classify small tissue patches into normal or tumor. Based on the patch-level classification, tumor probability heatmaps can be overlaid on tissue images. We observed three different tissue patterns, including clear normal, clear tumor and ambiguous cases. We suggest that longer inspection time can be assigned to ambiguous cases compared to clear normal cases, increasing the accuracy and efficiency of histopathologic diagnosis by pre-evaluating the status of the WSIs. When the classifier was tested with completely different WSI dataset, the performance was not optimal because of the different tissue preparation quality. By including a small amount of data from the new dataset for training, the performance for the new dataset was much enhanced. These results indicated that WSI dataset should include tissues prepared from many different preparation conditions to construct a generalized tissue classifier. Thus, multi-national/multi-center dataset should be built for the application of deep learning in the real world medical practice.

ABSTRACT

PURPOSE: To investigate the relationship between thyroid abnormality and dry eye syndrome (DES) in a nationally representative Korean population. METHODS: A population-based prospective cross-sectional study was conducted, using the thyroid abnormality data set of the Korean National Health and Nutrition Examination Survey, 2010 – 2012. A total of 16,966 Korean participants with DES were enrolled in the study. RESULTS: The DES patients were predominantly women, non-smokers and non-drinkers, living in urban regions, with a low income and body mass index (BMI), and with a higher percentage of hypertension, hyperlipidemia, thyroid abnormalities, thyroid diseases, and thyroid cancers. After adjusting for all significant variables, thyroid abnormality (odds ratio [OR], 1.93; 95% confidence interval [CI], 1.43–2.61), thyroid disease (OR, 1.85; 95% CI, 1.37–2.52), and thyroid cancer (OR, 2.45; 95% CI, 1.06–5.67) were significantly associated with DES. There was also a significant association between DES and thyroid abnormalities (OR, 2.02; 95% CI, 1.47–2.76), thyroid diseases (OR, 1.93; 95% CI, 1.41–2.65), and thyroid cancer (OR, 2.62; 95% CI, 1.06–6.62) in the female group, but there was no significant association in the male group. CONCLUSIONS: Thyroid abnormalities, thyroid diseases, and thyroid cancers were associated with DES in a nationally representative Korean population. Close evaluation of thyroid abnormalities is therefore needed when treating female patients.

ABSTRACT

OBJECTIVE: To examine whether bone mineral density (BMD) is causally associated with osteoarthritis (OA). METHODS: We performed a two-sample Mendelian randomization (MR) analysis using the inverse-variance weighting (IVW), weighted median, and MR-Egger regression methods. We used publicly available summary statistics datasets of a genome-wide association study (GWAS) on femur neck (FN) BMD of individuals of European ancestry as the exposure and a GWAS for non-cancer illness code self-reported: OA from the individuals included in the UK Biobank as the outcome. RESULTS: We selected 21 independent single-nucleotide polymorphisms with genome-wide significance (p<5.00E-08) from GWAS on FN BMD as the instrumental variables. The IVW method (beta=0.010, standard error [SE]=0.003, p=0.002) and the weighted median approach (beta=0.011, SE=0.004, p=0.006) yielded evidence of a causal association between FN BMD and OA. However, the MR-Egger analysis showed no causal association between FN BMD and OA (beta=0.005, SE=0.017, p=0.753). Since MR-Egger regression suffers from a lack of power and a susceptibility to weak instrument bias, the MR analysis results may support a causal association between FN BMD and OA. CONCLUSION: The results of MR analysis by IVW and weighted median, but not MR-Egger regression indicate that FN BMD is likely to be causally associated with an increased risk of OA incidence The current findings may provide an opportunity to elucidate the underlying mechanisms of the effects of BMD on the OA incidence.

ABSTRACT

OBJECTIVE: This study aimed to examine whether rheumatoid arthritis (RA) is causally associated with type 2 diabetes (T2D). METHODS: We performed a two-sample Mendelian randomization (MR) analysis using the inverse-variance weighted (IVW), weighted median, and MR-Egger regression methods. We used the publicly available summary statistics datasets from a genome-wide association studies (GWAS) meta-analysis of 5,539 autoantibody-positive individuals with RA and 20,169 controls of European descent, and a GWAS dataset of 10,247 individuals with T2D and 53,924 controls, overwhelmingly of European descent as outcomes. RESULTS: We selected 10 single-nucleotide polymorphisms from GWAS data on RA as instrumental variables to improve the inference. The IVW method supported a causal association between RA and T2D (β=0.044, standard error [SE]=0.022, p=0.047). The MR-Egger analysis showed a causal association between RA and T2D (β=0.093, SE=0.033, p=0.023). In addition, the weighted median approach supported a causal association between RA and T2D (β=0.056, SE=0.025, p=0.028). The association between RA and T2D was consistently observed using IVW, MR Egger, and weighted median methods. Cochran's Q test indicated no evidence of heterogeneity between instrumental variable estimates based on individual variants and MR-Egger regression revealed that directional pleiotropy was unlikely to have biased the results (intercept=−0.030; p=0.101). CONCLUSION: MR analysis supports that RA may be causally associated with an increased risk of T2D.

ABSTRACT

OBJECTIVES: To identify simultaneous behavioral changes in alcohol consumption, smoking, and weight using a fixed-effect model and to characterize their associations with disease status. METHODS: This study included 7 000 529 individuals who participated in the national biennial health-screening program every 2 years from 2009 to 2016 and were aged 40 or more. We reconstructed the data into an individual-level panel dataset with 4 waves. We used a fixed-effect model for smoking, heavy alcohol drinking, and overweight. The independent variables were sex, age, lifestyle factors, insurance contribution, employment status, and disease status. RESULTS: Becoming a high-risk drinker and losing weight were associated with initiation or resumption of smoking. Initiation or resumption of smoking and weight gain were associated with non-high-risk drinkers becoming high-risk drinkers. Smoking cessation and becoming a high-risk drinker were associated with normal-weight participants becoming overweight. Participants with newly acquired diabetes mellitus, ischemic heart disease, stroke, and cancer tended to stop smoking, discontinue high-risk drinking, and return to a normal weight. CONCLUSIONS: These results obtained using a large-scale population-based database documented interactions among lifestyle factors over time.

ABSTRACT

OBJECTIVES: Stillbirth is a common adverse pregnancy outcome that represents a distressing and traumatic event for women and their partners. The aim of this study was to identify factors associated with stillbirth in ever-pregnant women in Nepal. METHODS: This study utilized the individual women's dataset from the Nepal Demographic and Health Survey, conducted in 2016. The dependent variable of interest was whether women had at least 1 stillbirth during their lifetime. The associations between independent variables and the dependent variable of the study were analyzed using a multiple logistic regression model. RESULTS: Among 8918 ever-pregnant women aged 15-49 years, 488 had experienced at least 1 stillbirth during their lifetime, representing 5.5% of the total. After adjusting each factor for the confounding effects of other factors, maternal age, maternal education, place of residence, and sub-region remained significantly associated with having experienced stillbirth. CONCLUSIONS: Stillbirth continues to be a major problem among women, especially those with higher maternal age, those who are illiterate, and residents of certain geographical regions. To minimize stillbirth in Nepal, plans and policies should be focused on women with low education levels and residents of rural areas, especially in the western mountain and far-western hill regions.
