Obesity is an increasing health challenge and is recognized as a breast cancer risk factor. Although obesity-related breast cancer mechanisms are not fully understood, this association has been linked to impaired hormone secretion by the dysfunctional obese adipose tissue (hyperplasic and hypertrophic adipocytes). Among these hormones, altered production of androgens and adipokines is observed, and both, are independently associated with breast cancer development. In this review, we describe and comment on the relationships reported between these factors and breast cancer, focusing on the biological associations that have helped to unveil the mechanisms by which signaling from androgens and adipokines modifies the behavior of mammary epithelial cells. Furthermore, we discuss the potential crosstalk between the two most abundant adipokines produced by the adipose tissue (adiponectin and leptin) and the androgen receptor, an emerging marker in breast cancer. The identification and understanding of interactions among adipokines and the androgen receptor in cancer cells are necessary to guide the development of new therapeutic approaches in order to prevent and cure obesity and breast cancer.This study aimed to evaluate the prevalence of burnout syndrome in a sample of residents from different specialties, to determine the influence of work-related factors on the development of burnout, and to examine the mediating role of burnout in the relation between such work factors and perceived errors in clinical practice. A total of 237 Spanish residents participated (Mage = 28.87, SD = 3.84; 73.8% females). The Maslach Burnout Inventory and an ad hoc questionnaire were administered to assess burnout and work-related factors. Comparison analyses and mediational models were conducted. Half of the residents reported high levels of burnout (48.9%). Burnout was significantly associated with perceived errors in clinical practice. Significant differences were found between residents with lower and higher burnout levels, showing that those with higher burnout were less satisfied with the working conditions. find more Burnout mediated the associations between adjustment of responsibility, support among residents, satisfaction with teaching and rotations, general satisfaction, and perceived errors in the clinical practice. Adjusted levels of responsibility and workload, enhanced supervision, and more social support from colleagues predict lower levels of burnout, which may result in fewer errors in clinical practice. Consequently, such work-related factors should be taken into account as a preventive strategy for burnout and errors in the clinical practice so adequate patient care, good mental health of future specialists, and, therefore, higher quality of public health care can be ensured.In the present study, we report the development of poly (vinyl alcohol) (PVA) and chitosan oligosaccharide (COS)-based novel blend films. The concentration of COS was varied between 2.5-10.0 wt% within the films. The inclusion of COS added a brown hue to the films. FTIR spectroscopy revealed that the extent of intermolecular hydrogen bonding was most prominent in the film that contained 5.0 wt% of COS. The diffractograms showed that COS altered the degree of crystallinity of the films in a composition-dependent manner. As evident from the thermal analysis, COS content profoundly impacted the evaporation of water molecules from the composite films. Stress relaxation studies demonstrated that the blend films exhibited more mechanical stability as compared to the control film. The impedance profiles indicated the capacitive-dominant behavior of the prepared films. Ciprofloxacin HCl-loaded films showed excellent antimicrobial activity against Escherichia coli and Bacillus cereus. The prepared films were observed to be biocompatible. Hence, the prepared PVA/COS-based blend films may be explored for drug delivery applications.To evaluate the relative efficacy of novel retinoblastoma treatments, eye classification-specific success rates for current standard-of-care intravenous chemotherapy regimens must be known. This meta-analysis included studies if (1) patients received intravenous chemotherapy for retinoblastoma, (2) globe salvage data was reported, (3) only intravenous chemoreduction (with/without local consolidation) was used. The outcome measure was globe salvage success without need for salvage radiotherapy, subdivided by disease classification and chemotherapy regimen. Data from 27 studies (1483 eyes) were pooled. By Reese-Ellsworth classification, globe salvage rates were 85% (95%CI73-92%) for Group I, 78% (95%CI70-85%) for Group II, 68% (95%CI56-78%) for Group III, 47% (95%CI34-60%) for Group IV, and 35% (95%CI26-45%) for Group V (Va 35% [95%CI21-54%]; Vb 42% [95%CI29-56%]; those without sub-classification 31% [95%CI19-47%]). By International Classification, globe salvage rates were 93% (95%CI80-97%) for Group A, 83% (95%CI73-89%) for Group B, 73% (95%CI54-86%) for Group C, 40% (95%CI31-51%) for Group D, and 19% (95%CI5-50%) for Group E. Standard carboplatin-etoposide-vincristine out-performed two-drug regimens (odds ratio (OR) = 1.9 (95%CI1.3-3.0) for Groups I-IV and OR = 2.1 (95%CI1.3-3.4) for Group V; p = 0.002 for each). For eyes with diffuse vitreous seeds (Vb), an enhanced regimen out-performed standard chemotherapy (OR = 2.4 [95%CI1.3-4.7]; p = 0.004). In conclusion, two-drug regimens were less effective for all eyes, whereas enhanced regimens were more effective for eyes with vitreous seeds. Novel therapies can now be compared to these baseline globe salvage rates.The homeostasis of trace elements were observed to contribute to certain diabetic outcomes. This cross-sectional study determined the differences and associations between serum levels of copper (Cu), iron (Fe) and zinc (Zn) in Saudi patients with and without type 2 diabetes mellitus (T2DM) as well as those with prediabetes. Anthropometrics were measured, and fasting blood samples were collected from 119 patients with T2DM (aged 41-64 years), 95 non-T2DM (aged 27-55 years) and 80 with prediabetes (aged 35-57 years). Circulating trace minerals were determined using an inductively coupled plasma-mass spectrometer. Serum levels of Cu and Fe were significantly lower in T2DM than non-T2DM (adjusted p-values less then 0.001). There was no difference in the Zn levels of the T2DM and non-T2DM groups. The serum Cu levels were significantly lower in the prediabetes group than the non-T2DM group (p less then 0.05). The serum levels of Cu, Fe and Zn were inversely associated with circulating glucose in the T2DM and prediabetes subjects (p-values less then 0.
