The present study sought to investigate the associations between workplace bullying and personal burnout both directly and indirectly via work-life conflict. Furthermore, the moderating role of gender in these relations was examined. Traditional research on stress at work focuses on the role of dimensions related to job tasks, demands, and organizational support in influencing the risks for stress-related problems in employees. At the same time, other experiences at work may reduce employees' well-being, such as workplace bullying and family life. Specifically, considering the detrimental role of work-life conflict, it is possible to hypothesize that it would exacerbate workplace bullying's harmful effects on employees' health. Moreover, since previous studies have reported mixed or inconsistent results when considering gender differences with the above-mentioned dimensions, it seems worth investigating the role of employee gender in representing (and response to) the bullying experiences. Building on these cture, especially concerning a less studied occupation, namely school principals, shedding a new light on their work experiences. Furthermore, the present study offers interesting implications for trainings on principal's skills and professional identity.The paper describes the mechanical properties, determined on the basis of a tensile strength test of a composite material based on glass-fiber reinforced polyamide and obtained by Selective Laser Sintering-SLS. The material used is PA 3200 GF. Thin walled samples with non-standard nominal thicknesses of 1, 1.4 and 1.8 mm, manufactured in three printing directions X, Y and Z, were used. The description included the impact of printing direction on the geometry of the obtained samples and tensile strength as well as the dependency of tensile strength on the sample thickness. The results can be useful for design engineers and process engineers designing thin-walled components produced with SLS. Thin samples were obtained with a considerable deviation spread of the actual dimension from the nominal one. It was found that the tensile strength of thin samples is much lower than those of standard cross-sections, which should be taken into account in the design of thin-walled elements.

Endoscopic management of common bile duct stones (CBDS) is standard; however, various techniques are performed via the papilla, and the best procedure in terms of both efficacy and safety has not been determined.

Endoscopic procedures were classified into five categories according to endoscopic sphincterotomy (EST) and balloon dilation (BD) (1) EST, (2) endoscopic papillary BD (≤10 mm) (EPBD), (3) EST followed by BD (≤10 mm) (ESBD), (4) endoscopic papillary large BD (≥12 mm) (EPLBD), and (5) EST followed by large BD (≥12 mm) (ESLBD). We performed a literature review of prospective and retrospective studies to compare efficacy and adverse events (AEs). Each procedure was associated with different efficacy and AE profiles.

In total, 19 prospective and seven retrospective studies with a total of 3930 patients were included in this study. For EST, the complete stone removal rate at the first session, rate of mechanical lithotripsy (ML), and rate of overall AEs in EST were superior to EPBD, but a higher rate of bleeding was found for EST. Based on one retrospective study, complete stone removal rate at the first session, rate of ML, and rate of overall AEs were superior for ESBD vs. EST, and the rate of bleeding for the former was also lower. Complete stone removal rate at the first session and rate of ML for ESLBD were superior to those for EST, with no significant difference in rate of AEs. For EST vs. EPLBD, complete stone removal rate at the first session and rate of ML were superior for the latter. For EPLBD vs. ESLBD, the efficacy and safety were similar.

ESBD is considered the best procedure for the management of small CBDS, but strong evidence is lacking. For large CBDS, both ESLBD and EPLBD are similar.

ESBD is considered the best procedure for the management of small CBDS, but strong evidence is lacking. For large CBDS, both ESLBD and EPLBD are similar.Obesity-associated low-grade inflammation favors weight gain, whereas systemic infection frequently leads to anorexia. Thus, inflammatory signals can either induce positive or negative energy balance. In this study, we used whole-cell patch-clamp to investigate the acute effects of three important proinflammatory cytokines, tumor necrosis factor α (TNF-α), interleukin-6, and interleukin-1β (IL-1β) on the membrane excitability of agouti-related peptide (AgRP)- or proopiomelanocortin (POMC)-producing neurons. We found that both TNF-α and IL-1β acutely inhibited the activity of 35-42% of AgRP-producing neurons, whereas very few POMC neurons were depolarized by TNF-α. Interleukin-6 induced no acute changes in the activity of AgRP or POMC neurons. Our findings indicate that the effect of TNF-α and IL-1β, especially on the activity of AgRP-producing neurons, may contribute to inflammation-induced anorexia observed during acute inflammatory conditions.Multiple Sclerosis (MS) is a progressive neurodegenerative disease that affects more than 2 million people worldwide. Increasing knowledge about MS in different populations has advanced our understanding of disease epidemiology and variation in the natural history of MS among White and minority populations. In addition to differences in incidence, African American (AA) and Hispanic patients have greater disease burden and disability in earlier stages of disease compared to White patients. To further characterize MS in AA and Hispanic populations, we conducted a retrospective chart analysis of 112 patients treated at an MS center in Houston, Texas. Here, we describe similarities and differences in clinical presentation, MRI findings, treatment regimens, disability progression, and relapse rate. While we found several similarities between the groups regarding mean age, disability severity, and degree of brain atrophy at diagnosis, we also describe a few divergences. Interestingly, we found that patients who were evaluated by a neurologist at symptom onset had significantly decreased odds of greater disability [defined as Expanded Disability Status Scale (EDSS) > 4.5] at last presentation compared to patients who were not evaluated by a neurologist (OR 0.04, 95% CI 0.16-0.9). We also found that active smokers had significantly increased odds of greater disability both at diagnosis and at last clinical encounter compared to nonsmokers (OR 2.44, 95% CI 1.10-7.10, OR= 2.44, 95% CI 1.35-6.12, p = 0.01, respectively). Additionally, we observed significant differences in treatment adherence between groups. Assessment of the degree of brain atrophy and progression over time, along with an enumeration of T1, T2, and gadolinium-enhancing brain lesions, did not reveal differences across groups.The diagnosis of intracranial meningiomas as incidental findings is increasing by growing availability of MRI diagnostics. However, the psychological distress of patients with incidental meningiomas under a wait-and-watch strategy is unknown. Therefore, we aimed to compare the psychosocial situation of meningioma patients under wait-and-watch to patients after complete resection to bridge this gap. The inclusion criteria for the prospective monocenter study were either an incidental meningioma under a wait-and-watch strategy or no neurologic deficits after complete resection. Sociodemographic, clinical, and health-related quality of life and clinical data were assessed. Psychosocial factors were measured by the Distress Thermometer (DT), Hospital Anxiety and Depression Scale (HADS), Brief Fatigue Inventory (BFI), and the Short Form (SF-36). A total of 62 patients were included (n = 51 female, mean age 61 (SD 13) years). According to HADS, the prevalence of anxiety was 45% in the postoperative and 42% in the wait-and-watch group (p = 0.60), and depression was 61% and 87%, respectively (p = 0.005). In total, 43% of patients under wait-and-watch and 37% of patients in the postoperative group scored ≥6 on the DT scale. SF-36 scores were similar in all categories except general health (p = 0.005) and physical component aggregate score (43.7 (13.6) vs. 50.5 (9.5), (p = 0.03), both lower in the wait-and-watch group. Multivariate analysis revealed the wait-and-watch strategy was associated with a 4.26-fold higher risk of a pathological depression score based on HADS (p = 0.03). This study demonstrates a high prevalence of psychological distress in meningioma patients. Further evaluation is necessary to identify the patients in need of psychooncological support.The objective of this paper was twofold. First, we estimated consumer preferences for an Italian cheese (Provolone Valpadana) with respect to several attributes and levels, such as price, origin certification, production system, 'free from' labelling, and brand. Second, we identified consumer clusters with similar preferences for various cheese characteristics. Preferences were estimated using the conjoint analysis method. Then, a cluster analysis was used to classify consumers into different (three) clusters followed by a market simulation. In all three clusters, the attribute most preferred by Italian consumers was the brand of the cheese consumers preferred to purchase Provolone cheese having the lowest price, produced by Auricchio, bearing a European Union (EU) quality certification, produced organically, and non-lactose-free. The results of our study provide helpful information to food companies for better segmenting their market and targeting their consumers, as well as effectively promoting their products using brands, certifications as organic and lactose-free. This study contributes to the literature on consumer preference for the EU labelling scheme (voluntary and mandatory). To our knowledge, this is the first study to investigate this combination of multiple labels displayed on the front of Italian cheese packaging.A recent study of the ischemic stroke described the roles played by miRNAs in the downregulation of specific cell-cycle gene expression and it is thought to require the development of biomarkers for the prognostic of ischemic stroke. Here, we hypothesized that four miRNA polymorphisms (miR-10a, miR-27a, miR-34b/c, and miR-300) may affect stroke susceptibility and mortality. Blood samples were collected from 530 patients and 403 controls. Amlexanox research buy Genetic polymorphisms were detected by polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis and real-time PCR. We found that the miR-300 rs12894467 TC genotype and the dominant model (AOR 2.069, p-value 0.017; AOR 1.931, p-value 0.027) were significantly associated with an increased risk for the ischemic stroke subtype. In Cox proportional hazard regression models, the miR-10a rs3809783 A>T and miR-34b/c rs4938723 T>C polymorphisms were associated with the mortality rates among ischemic stroke patients. We found that a miR-300 polymorphism was associated with increased ischemic stroke susceptibility among the Korean population. Additionally, polymorphisms in miR-10a and miR-34b/c were associated with the increased or decreased mortality of ischemic stroke patients. This study marks the first report of an association between ischemic stroke and miRNA polymorphisms (miR-10aA>T, miR-27aT>C, miR-34b/cT>C, and miR-300T>C) in the Korean population.
