Reduction of social interaction and increase of defensive behavioral attitude was associated with older groups of age. In this study, two subgroups of subjects with a steeper cortisol secretion (slope significant non-zero), and flatter cortisol secretion (slope no significant non-zero) were detected. Noticeable, we detected and association between measurements of cortisol secretion from subjects with a flatter cortisol dynamic range and behavioral defensive and inhibition of social interaction indexes.

These findings suggested chronical dysregulation of HPA axis as a result of perseverative cognitive perception of unsafety environment which may be precedent to cognitive impairment in the population.

Evidence suggests that psychosocial factors are associated with cognitive health in older adults; however, associations of psychosocial factors with cognition remain largely unexamined in middle-aged and older Hispanics/Latinos.

To examine the cross-sectional associations of psychosocial factors with cognitive function among middle-aged and older Hispanics/Latinos living in the US.

Baseline (2008-2011) data from the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (n = 2,818; ages 45-74) were used to examine the associations of each psychosocial factor with global cognition (GC), verbal learning, verbal memory, verbal fluency, and processing speed independent of age, sex, education, Hispanic/Latino background, income, language, and depressive symptoms. Psychosocial variables included intrapersonal factors (ethnic identity, optimism, and purpose in life), interpersonal factors (family cohesion, familism, social network embeddedness, and social support), and social stressors strongly associated with cognitive health among middle-aged and older Hispanics/Latinos. We also highlight that intrapersonal factors, interpersonal factors, and social stressors have differential relationships with individual cognitive tests.Mitochondria perform many essential cellular functions including energy production, calcium homeostasis, transduction of metabolic and stress signals, and mediating cell survival and death. Maintaining viable populations of mitochondria is therefore critical for normal cell function. The selective disposal of damaged mitochondria, by a pathway known as mitophagy, plays a key role in preserving mitochondrial integrity and quality. Mitophagy reduces the formation of reactive oxygen species and is considered as a protective cellular process. Mitochondrial dysfunction and deficits of mitophagy have important roles in aging and especially in neurodegenerative disorders such as Alzheimer’s disease (AD). Targeting mitophagy pathways has been suggested to have potential therapeutic effects against AD. In this review, we aim to briefly discuss the emerging concepts on mitophagy, molecular regulation of the mitophagy process, current mitophagy detection methods, and mitophagy dysfunction in AD. Finally, we will also briefly examine the stimulation of mitophagy as an approach for attenuating neurodegeneration in AD.

Coronavirus disease 2019 (COVID-19) can cause acute respiratory distress Syndrome (ARDS).

This single centre cross-section study aimed to grade the severity of pneumonia by bed-side lung ultrasound (LUS).

A scoring system discriminates 5 levels of lung opacities A-lines (0 points),≥3 B-Line (1 point), coalescent B-Lines (2 points), marked pleural disruptions (3 points), consolidations (4 points). LUS (convex 1-5 MHz probe) was performed at 6 defined regions for each hemithorax either in supine or prone position. A lung aeration score (LAS, maximum 4 points) was allocated for each patient by calculating the arithmetic mean of the examined lung areas. Score levels were correlated with ventilation parameters and laboratory markers.

LAS of 20 patients with ARDS reached from 2.58 to 3.83 and was highest in the lateral right lobe (Mean 3.67). Ferritin levels (Mean 1885μg/l; r = 0.467; p = 0.051) showed moderate correlation in spearman roh calculation. PaCO2 level (Mean 46.75 mmHg; r = 0.632; p = 0.005) correlated significantly with LAS, while duration of ventilation, Horovitz-Index, CRP, LDH and IL-6 did not.

The proposed LAS describes severity of lung opacities in COVID-19 patients and correlates with CO2 retention in patients with ARDS.

So, detection of molecular biomarkers that help in monitoring the disease, evaluating the prognosis of the patients, and their response to therapy is needed. In this study, we investigated the expression and the prognostic significance of SATB-1 and ERBB2 mRNA and protein by quantitative RT-PCR and immunohistochemical analysis in urothelial bladder cancer cases and the surrounding normal bladder tissue. The correlations between the expression of both markers and the clinicopathological parameters were performed with further analysis of the correlation between the expression of SATB-1 and ERBB2. Terfenadine nmr Compared to control, the expression of SATB-1 and ERBB2 mRNA and protein in cancer tissues were significantly up-regulated (p less then 0.05). Also, a positive correlation between both markers was found (r= 0.53, p less then 0.001). Moreover, elevated levels of both markers were significantly associated with the stage, lymph node involvement at both mRNA and protein levels (p less then 0.001). In conclusion, there is a clinical significance of SATB-1 and ERBB2 as potential biomarkers for predicting bladder cancer patients of aggressive behavior and poor prognosis.

Adolescent idiopathic scoliosis screening still needs a considerable implementation, particularly throughout a school-based assessment protocol.

This study aims to evaluate the effectiveness of clinical examinations currently in use for the diagnosis of adolescent idiopathic scoliosis, through a survey carried out in secondary schools to standardize a screening protocol that could be generalized.

In their classrooms, the adolescents underwent an idiopathic scoliosis screening through three examinations Adam’s test, axial trunk rotation (ATR) and plumb line. In case of single positivity to one of the three examinations, a column X-ray examination was recommended.

The sensitivity and diagnostic specificity of Adam’s test or ATR were 56.3% and 92.7%, respectively. The positivity to at least one between ATR or plumb line showed that sensitivity was higher than specificity 91.3% versus 80.8%; the positivity to at least one between Adams’s test or plumb line showed a sensitivity of 95.2% and a specificity of 81.
