Parathyroid tumors are the second most common endocrine neoplasia after thyroid neoplasia. They are mostly associated with impaired parathormone (PTH) synthesis and release determining the metabolic and clinical condition of primary hyperparathyroidism (PHPT). PHPT is the third most prevalent endocrine disorder, mainly affecting postmenopausal women. selleck compound Parathyroid benign tumors, both adenomas of a single gland or hyperplasia involving all the glands, are the main histotypes, occurring in more than 95% of PHPT cases. The differential diagnosis between benign and malignant parathyroid lesions is a challenge for clinicians. It relies on histologic features, which display significant overlap between the histotypes with different clinical outcomes. Parathyroid adenomas and hyperplasia have been considered so far as a unique monoclonal/polyclonal entity, while accumulating evidence suggest great heterogeneity. Intratumor parathyroid heterogeneity involves tumor cell type, as well as tumor cell function, in terms of PTH synthesis and secretion, and of expression patterns of membrane and nuclear receptors (calcium sensing receptor, vitamin D receptor, α-klotho receptor and others). Intratumor heterogeneity can also interfere with cell molecular biology, in regard to clonality, oncosuppressor gene expression (such as MEN1 and HRPT2/CDC73), transcription factors (GCM2, TBX1) and microRNA expression. Such heterogeneity is likely involved in the phenotypic variability of the parathyroid tumors, and it should be considered in the clinical management, though at present target therapies are not available, with the exception of the calcium sensing receptor agonists.Purpose Bariatric surgery (BS) is considered the most effective treatment for severe obesity. Nevertheless, long-term studies have identified some concerning issues, such as increased postoperative rates of suicide and substance use disorders. Some investigators have postulated that these postoperative issues might result from differences in psychological characteristics between patients with obesity seeking BS and those seeking non-surgical (medical) care. The aim of this study was to explore the psychological differences between patients seeking BS and those seeking non-surgical care. Methods 151 patients seeking BS (BS group) and 95 patients seeking medical care (non-surgery group) completed questionnaires measuring depression, anxiety, self-esteem, body dissatisfaction, hopelessness and weight-loss expectations (WLE). Results There were no differences between the BS and non-surgery groups in depression, anxiety or self-esteem. Body dissatisfaction and WLE were greater in the BS group than in the non-surgery group. Contrary to our hypothesis, the non-surgery group showed higher levels of hopelessness than the BS group. Correlation analyses revealed very similar associations between psychological characteristics for both groups. Hierarchical regression and moderation analyses identified self-esteem as the factor most predictive of hopelessness in both groups. Conclusions We found few differences in psychological characteristics between groups. The lower level of hopelessness in the BS group might be seen as a form of protection leading up to surgery but may result from the patient's view of BS as their "last best hope". Further studies are needed to understand the evolution of these psychological characteristics after surgery and their possible effects on postoperative outcomes. Level of evidence Level III, case-control analytic studies.Purpose The purpose of this study was to examine the influence of mother-daughter communication about their bodies on adolescent girls' and mothers' body shame. Methods The Actor-Partner Interdependence Model was utilized to estimate relationships between individuals' body surveillance and their own body shame (actor effect), individuals' body surveillance and the other member's body shame (partner effect), and negative body talk and both members' body shame (relationship effect) in a sample of 100 mother-daughter dyads. Results For both mothers and daughters, individuals who had higher body surveillance reported higher body shame. Negative body talk emerged as a significant moderator girls with higher body surveillance experienced greater body shame when they engaged in more negative body talk with their mothers. Conclusion The findings highlight the need for clinicians to address mothers' own surveillance and body shame, as well as negative body talk between mothers and daughters, in interventions that seek to reduce the impact of objectification on body shame in adolescents. Level of evidence Level V, cross-sectional descriptive study.Taking as a starting point that the only proving method in mathematics is logic, as, for example, is used in the logical setup of the paper (arguments, i.e., premises leading to conclusions, logical inferences), we describe a new tool for analysis and validation of publications in the field of bioinformatics. In striking contrast to the abundance of statistical programs and packages available to bioinformatics researchers, no such logical tool is available to them. Therefore the creation of such a tool is necessary; a form of expert system that may do the following procedures Evaluate papers giving a score of logical consistency and completeness (i.e., how many conclusions were investigated in comparison to all possible conclusions based on the set of premises used by the researchers). Help researchers and academics better plan their protocols by automating the process of analysis of the premises given. Be able to locate and analyze arguments directly from the text of the scientific paper, from certain parts of it (e.g., the "conclusions" section, or even from the whole text, based on advanced AI algorithms). Provide a new standard for future publications in any form and, later, in any scientific field.Background The European Health Risk Assessment Network on Electromagnetic Fields Exposure (EFHRAN) reported in 2012 "Children and adolescents represent the first generation of Europeans to be exposed to diffuse EMF since their conception and birth, thus, they are expected to be more sensitive to these fields." On the other hand, the body's physiologic processes are regulated by the autonomic nervous system (ANS) in a way that warrants further elucidation. Objective Age and duration of exposure are investigated for modifying the variance of the reported effects of mobile/cellular phone call (CPC) on ANS indexed, herein, by the heart rate variability (HRV). Method Five studies targeted to 124 healthy subjects (aged 15.3-28.4 years (24.3 ± 5.2), who have been recorded in supine position before and/or sham versus real exposure (to a CPC lasting 5-32 minutes), are included in this meta-analysis. Age and duration of a CPC are evaluated as predictors in two separate meta-regressions. Results The meta-analysis identified a heterogeneity I2 = 63.
