Dimensionamento das armaduras de compressão em chapas de concreto armado

This paper presents a method to design membrane elements of concrete with orthogonal mesh of reinforcement which are subject to compressive stress. Design methods, in general, define how to quantify the reinforcement necessary to support the tension stress and verify if the compression in concrete is within the strength limit. In case the compression in membrane is excessive, it is possible to use reinforcements subject to compression. However, there is not much information in the literature about how to design reinforcement for these cases. For that, this paper presents a procedure which uses the model based on Baumann's [1] criteria. The strength limits used herein are those recommended by CEB [3], however, a model is proposed in which this limit varies according to the tensile strain which occur perpendicular to compression. This resistance model is based on concepts proposed by Vecchio e Collins [2]

A systematic review and meta-analysis were conducted to examine the cross-cultural correlates of self-stigma among individuals with schizophrenia spectrum disorders

Evaluation of non-exudative microcystoid macular abnormalities secondary to retinal vein occlusion.

PurposeWe aimed to investigate non-exudative microcystoid macular abnormalities for visual and anatomical outcome in patients with retinal vein occlusion (RVO) with and without glaucomatous optic neuropathy (GON).MethodsMedical records of 124 eyes (105 patients) with RVO were reviewed and analyzed. Eyes demonstrating microcystoid macular abnormalities were divided into 2 groups, those with evidence of glaucoma (group A) and those without glaucoma (group B). Best-corrected visual acuity (BCVA), the prevalence and number of microcystoid macular abnormalities, and number of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections were compared at baseline and follow-up.ResultsSeventy-one out of 105 eyes (67.6%) with RVO displayed microcystoid macular abnormalities. Thirty-eight out of 71 eyes (53.5%) presented with concomitant glaucoma (group A), while the remaining 33 eyes (42.6%) had no history of glaucoma (group B). At the end of the follow-up period, mean BCVA was worse in group A versus group B (20/80 versus 20/40, respectively; p = .003). The mean number of anti-VEGF injections was 10.1 ± 9.2 in group A versus 5.9 ± 6.9 in group B (p = .03).ConclusionEyes with RVO and concomitant glaucoma exhibited a significantly higher number of microcystoid macular abnormalities and worse BCVA versus eyes with RVO without glaucoma

Transdiagnostic cognitive biases in psychiatric disorders: A systematic review and network meta-analysis

Psychiatric disorders are characterized by cognitive deficits, which have been proposed as a transdiagnostic feature of psychopathology (“C” factor). Similarly, cognitive biases (e.g., in attention, memory, and interpretation) represent common tendencies in information processing that are often associated with psychiatric symptoms. However, the question remains whether cognitive biases are also transdiagnostic or are specific to certain psychiatric disorders/symptoms. The current systematic review (osf.io/znf4q) sought to address whether the proposed “C” factor of transdiagnostic cognitive dysfunction in psychopathology can be extended to cognitive biases. Overall, 31 studies comprising 4401 participants (2536 patients, 1865 non-clinical controls) across 21 diagnostic categories met inclusion criteria, assessing 19 cognitive biases with most studies focusing on interpretation (k = 22) and attention (k = 11) biases, with only 2 assessing memory biases. Traditional meta-analyses found a moderate effect size (g = 0.32) for more severe cognitive biases in all patients relative to non-clinical controls, as well as small but significant associations between interpretation biases and transdiagnostic symptom categories (general psychopathology: r = .20, emotion dysfunction: r = 0.17, psychotic symptoms: r = 0.25). Network meta-analyses revealed significant patient versus control differences on attention and interpretation biases across diagnoses, as well as significant differences between diagnoses, with highest severity in panic disorder for attention biases and obsessive-compulsive disorder for interpretation biases. The current findings support a big “C” interpretation of transdiagnostic cognitive dysfunction in psychiatric disorders, extending the concept to cognitive biases and transdiagnostic symptom dimensions. They also suggest that while the presence of cognitive biases is transdiagnostic, bias severity differs across diagnoses, as in traditional neurocognitive deficits

An intersectional perspective on the sociodemographic and clinical factors influencing the status of Not in Education, Employment, or Training (NEET) in patients with first-episode psychosis (FEP)

Following the onset of a First Episode of Psychosis (FEP), the rate of individuals Not in Education, Employment, or Training (NEET) appears to drastically increase. Sociodemographic and clinical factors were reported to be associated with NEET status in FEP patients. This study examined how these sociodemographic and clinical factors were linked to NEET status in FEP patients independently and from an intersectional perspective. It was hypothesized that NEET status in FEP patients would be described by the intersection between at least two predictor variables. Secondary analyses were conducted on files of participants recruited from a local FEP clinic. Univariate logistic regression and Chi-squared Automatic Interaction Detection (CHAID) analyses were performed on a total of 440 participants with FEP. Univariate logistic regressions indicated that age (p = .03), socioeconomic status (p < .001), and negative symptom severity (p < .001) were significant independent predictors of NEET. CHAID analyses suggested an intersectional pattern of negative symptom severity and socioeconomic status in differentiating between FEP patients with NEET versus non-NEET status. The applicability and generalizability of results from this study were enhanced by the large and representative sample as well as the use of benchmark quantitative intersectionality research methods. Future intersectionality research on NEET with a clinical population is needed to validate and expand the current results by including more sociodemographic variables

Degenerative Peripheral Retinoschisis: Observations From Ultra-Widefield Fundus Imaging.

BACKGROUND AND OBJECTIVE: To describe the ultra-widefield (UWF) imaging characteristics of patients with degenerative peripheral retinoschisis (DPR) using Optomap technology. PATIENTS AND METHODS: In this multicenter, retrospective, noncomparative, consecutive case series, eligible patients underwent detailed retinal examination including indirect ophthalmoscopy. UWF fundus imaging, including color fundus photography, autofluorescence, and angiography, was performed using standardized protocols and findings were recorded and reviewed and analyzed. RESULTS: A total of 35 patients (58 eyes) with DPR were identified who underwent 55 sessions of UWF imaging. Mean age was 65 years, and the inferotemporal quadrant was most commonly affected (74% of eyes). Of these patients, 31 underwent fluorescein angiography and 90% of these studies illustrated abnormalities in the area affected by the schisis. The most common finding was retinal vascular leakage originating from the deep capillary plexus observed in 29 eyes (93.5%). CONCLUSIONS: UWF imaging enables a more detailed identification of the clinical features associated with DPR and provides simple, practical, and noninvasive tools to monitor progression of disease. The breadth of retinal vascular complications identified with fluorescein angiography may suggest an important vascular component associated with the pathogenesis of this entity.
