In clinical environments, nursing students experience a range of stressors that can affect their health, learning, and quality of patient care. This study aimed to develop a Nursing Students' Perceptions of Clinical Stressors Scale (NSPCSS) and to evaluate its psychometric properties.

This exploratory, sequential mixed-method study was conducted in 2 phases. In the qualitative (item generation) phase, NSPCSS items were generated using the data collected from semi-structured interviews and a literature review. In the quantitative (psychometric evaluation) phase, face, content, construct, convergent, and discriminant validity and reliability of the scale were tested. To evaluate construct validity, exploratory and confirmatory factor analyses were performed on the data collected from 430 nursing students. Reliability was also assessed through internal consistency and composite reliability.

In this study, 6 factors were extracted from 30 itemes through exploratory factor analysis (1) instructor's limited competence in clinical environments, (2) inappropriate clinical environment, (3) inadequate knowledge and skills, (4) inefficient education in clinical planning, (5) instructor's inappropriate conduct, and (6) concerns about the characteristics of nursing career. These factors accounted for 58.8% of the total variance. The results of the confirmatory factor analysis suggested the goodness-of-fit indices was acceptable. selleck Furthermore, the internal consistency and composite reliability indices of all factors were greater than 0.7.

The NSPCSS is a valid and reliable instrument for assessing clinical stressors among nursing students.

Technology advancement has rising in the past decade and brought several innovations and improvements. In dentistry, this advances provided more comfortable and quick procedures to both the patient and the dental surgeon, generating less predictability in the final result. Several techniques has been developed for the preparation of surgical guides aiming at the optimization of surgical procedures. The present study aimed to evaluate the reproducibility and precision of two types of surgical guides obtained using 3D printing and milling methods.

A virtual model was developed that allowed the virtual design of milled (n = 10) or 3D printed (n = 10) surgical guides. The surgical guides were digitally oriented and overlapped on the virtual model. For the milling guides, the Sirona Dentsply system was used, while the 3D printing guides were produced using EnvisionTEC's Perfactory P4K Life Series 3D printer and E-Guide Tint, a biocompatible Class I certified material. The precision and trueness of each group during overlap were assessed. The data were analyzed with GraphPad software using the Kolmogorov-Smirnov test for normality and Student's t test for the variables.

The Kolmogorov-Smirnov test showed a normal distribution of the data. Comparisons between groups showed no statistically significant differences for trueness (p = 0.529) or precision (p = 0.3021). However, a significant difference was observed in the standard deviation of mismatches regarding accuracy from the master model (p < 0.0001).

Within the limits of this study, surgical guides fabricated by milling or prototyped processes achieved similar results.

Protein-peptide interactions play a fundamental role in a wide variety of biological processes, such as cell signaling, regulatory networks, immune responses, and enzyme inhibition. Peptides are characterized by low toxicity and small interface areas; therefore, they are good targets for therapeutic strategies, rational drug planning and protein inhibition. Approximately 10% of the ethical pharmaceutical market is protein/peptide-based. Furthermore, it is estimated that 40% of protein interactions are mediated by peptides. Despite the fast increase in the volume of biological data, particularly on sequences and structures, there remains a lack of broad and comprehensive protein-peptide databases and tools that allow the retrieval, characterization and understanding of protein-peptide recognition and consequently support peptide design.

We introduce Propedia, a comprehensive and up-to-date database with a web interface that permits clustering, searching and visualizing of protein-peptide complexes accordinis a database and tool to support structure-based rational design of peptides for special purposes. Protein-peptide interactions can be useful to predict, classifying and scoring complexes or for designing new molecules as well. Propedia is up-to-date as a ready-to-use webserver with a friendly and resourceful interface and is available at https//bioinfo.dcc.ufmg.br/propedia.

Syria has experienced war since 2011, leaving over 80% under the poverty line and millions displaced. War and its retaliations have significantly impacted the mental health of Syrians. This study evaluates the post-traumatic stress disorder (PTSD), and the severity of the mental distress caused by war and other factors such as low social support. This study also evaluates other variables and compares the findings with those of multiple studies on Syria and refugees.

This is a cross-sectional study that included people who lived in Syria in different governorates. Online surveys were distributed into multiple online groups and includedthe Kessler 10 (K10) scalewhich screens for anxiety and depression, the Screen for Posttraumatic Stress Symptoms (SPTSS) tool, the Multidimensional Scale of Perceived Social Support, and questionnaires ondemographic and war-related factors.

Our study included 1951 participants, of which, 527 (27.0%) were males and 1538 (78.8%) between the age of 19 and 25. Among participants, 44% had likely severe mental disorder, 27% had both likely severe mental disorder and full PTSD symptoms, 36.
