The role of miRNAs in the pathogenesis and therapeutic resistance of endometrial cancer: a spotlight on the convergence of signaling pathways.

Endometrial cancer (EC) is the 2nd common cancer in females after breast cancer. Besides, it's the most common among gynecological cancers. Several epigenetic factors such as miRNAs have been reported to affect EC aspects including initiation, progression, angiogenesis, and resistance to therapy. miRNAs could regulate the expression of various genes involved in EC pathogenesis. This effect is attributed to miRNAs' effects in proliferation, apoptosis, cell cycle, angiogenesis, invasion, and metastasis. miRNAs also influence crucial EC-related mechanistic pathways such as JAK/STAT axis, EGFR, TGF-ß signaling, and P53. Beside pathogenesis, miRNAs also have the potential to affect EC response to treatments including radio and chemotherapy. Thus, this review aims to illustrate the link between miRNAs and EC; focusing on the effects of miRNAs on EC signaling pathways.

Psychometric evaluation of the Depression Anxiety Stress Scale 8 among women with chronic non-cancer pelvic pain.

Psychiatric comorbidity and abusive experiences in chronic pelvic pain (CPP) conditions may prolong disease course. This study investigated the psychometrics of the Depression Anxiety Stress Scale 8 (DASS-8) among women with CPP (N = 214, mean age = 33.3 ± 12.4 years). The DASS-8 expressed excellent fit, invariance across age groups and menopausal status, good know-group validity (differentiating women with psychiatric comorbidity from those without comorbidity: U = 2018.0, p = 0.001), discriminant validity (HTMT ratios < 0.85), excellent reliability (alpha = 0.90), adequate predictive and convergent validity indicated by strong correlation with the DASS-21 (r = 0.94) and high values of item-total correlations (r = 0.884 to 0.893). In two-step cluster analysis, the DASS-8 classified women into low- and high-distress clusters (n = 141 and 73), with significantly higher levels of distress, pain severity and duration, and physical symptoms in cluster 2. The DASS-8 positively correlated with pain severity/duration, subjective symptoms of depression/anxiety, experiences of sexual assault, fatigue, headache severity, and collateral physical symptoms (e.g., dizziness, bloating, fatigue etc.) at the same level expressed by the parent scale and the DASS-12, or even greater. Accordingly, distress may represent a target for early identification of psychiatric comorbidity, CPP severity, experiences of sexual assault, and collateral physical complaints. Therefore, the DASS-8 is a useful brief measure, which may detect mental distress symptoms among women with CPP.

Psychometric evaluation of the depression anxiety stress scale 8-items (DASS-8)/DASS-12/DASS-21 among family caregivers of patients with dementia.

Patients with dementia express a set of problematic and deteriorating symptoms, along with self-care dependency. Over time, the mental health of family caregivers of persons with dementia may be affected, putting them at a high risk for psychopathology, which may be associated with endangered wellbeing of people with dementia. This cross-sectional instrumental design study examined the psychometric properties of the Depression Anxiety Stress Scale 8-items (DASS-8), DASS-12, and DASS-21 in a convenient sample of 571 caregivers from northern Italy and southern Switzerland (mean age = 53 years, SD = 12, range = 24-89 years). A bifactor structure of the three measures had the best fit; some items of the DASS-12/DASS-21 failed to load on their domain-specific factors. The three-factor structure was invariant across various groups (e.g., gender and education), expressed adequate reliability and convergent validity, and had strong positive correlation with the three-item UCLA Loneliness Scale (UCLALS3). Distress scores did not differ among carers of different types of dementia (Alzheimer's disease vs. other types, e.g., vascular dementia). However, distress scores were significantly high among female individuals, adult children caregivers, those caring for dependent patients, and those who received help with care. For 54.9 and 38.8% of the latter, care was provided by relatives and health professionals, respectively. Since the DASS-8 expresses adequate psychometrics comparable with the DASS-21, it may be used as a brief measure of distress in this population.

Are programmed cell death protein-1 and Angiopoietins-2 effective biomarkers for detection the severity of psoriatic patients?

BACKGROUND: Early detection of psoriasis is still an open discussion. Psoriatic lesions are characterized by red/scaly plaques affecting different body-sites. OBJECTIVES: To evaluate the levels of programmed cell death protein-1(PD-1) and Angiopoietins-2(Ang-2) in serum, lesional, and perilesional of psoriatic patients and correlate them with controls and disease severity. SUBJECTS AND METHODS: Serum samples were obtained from 40 participants subdivided equally into psoriatic and healthy controls, 4 mm punch_biopsy equally from lesional and perilesional skin of individuals. PD-1/ANG-2 ELISA kits were used for determining the serum and tissue levels among groups. RESULTS: Serum and tissue levels of PD-1 and Ang-2 were overexpressed in psoriatic patients compared with controls. There was a statistical difference between patients and controls in level of PD-1(serum and tissue) with p-value 0.006 and 0.0001, respectively. There was a statistical difference between both groups for ANG-2(serum and tissue) with p-value 0.03 and 0.0001, respectively. There were positive correlations between PASI score and PD-1 in tissue (r = 0.467, p = 0.038). Also, positive correlation between the level of PD-1 in serum and tissue (r = 0.369, p = 0.019), the serum levels of PD-1 and ANG-2 (r = 0.78, p > 0.0001), PD-1 and Ang-2 in tissue (r = 0.583,p = 0.0001) were detected. CONCLUSION: PD-1 and ANG-2 can be highly recommended to determine the severity of psoriasis.
