Gastric cancer (GC) is one of the most common deadly cancers in the world. Although patient genomic data have identified AT-rich interaction domain 1A (ARID1A), a key chromatin remodeling complex subunit, as the second most frequently mutated gene after TP53, its in vivo role and relationship to TP53 in gastric tumorigenesis remains unclear. Establishing a novel mouse model that reflects the ARID1A heterozygous mutations found in the majority of human GC cases, we demonstrated that Arid1a heterozygosity facilitates tumor progression through a global loss of enhancers and subsequent suppression of the p53 and apoptosis pathways. Moreover, mouse genetic and single-cell analyses demonstrated that the homozygous deletion of Arid1a confers a competitive disadvantage through the activation of the p53 pathway, highlighting its distinct dosage-dependent roles. Eeyarestatin 1 purchase Using this unique vulnerability of Arid1a mutated GC cells, our combined treatment with the epigenetic inhibitor, TP064, and the p53 agonist, Nutlin-3, inhibited growth of Arid1a heterozygous tumor organoids, providing a novel therapeutic option for GC.Familial Alzheimer's disease (FAD)-linked mutations in the APP gene occur either within the Aβ-coding region or immediately proximal and are located in exons 16 and 17, which encode Aβ peptides. We have identified an extremely rare, partially penetrant, single nucleotide variant (SNV), rs145081708, in APP that corresponds to a Ser198Pro substitution in exon 5. We now report that in stably transfected cells, expression of APP harboring the S198P mutation (APPS198P) leads to elevated production of Aβ peptides by an unconventional mechanism in which the folding and exit of APPS198P from the endoplasmic reticulum is accelerated. More importantly, coexpression of APP S198P and the FAD-linked PS1ΔE9 variant in the brains of male and female transgenic mice leads to elevated steady-state Aβ peptide levels and acceleration of Aβ deposition compared with age- and gender-matched mice expressing APP and PS1ΔE9. This is the first AD-linked mutation in APP present outside of exons 16 and 17 that enhances Aβ production and deposition.
A low proportion of bystanders in Slovenia are willing to provide resuscitation to people experiencing cardiac arrest. We measured knowledge acquired after cardiopulmonary resuscitation training among Slovenian children in the final three grades of primary school.
This pre- and post-test cohort study included 566 schoolchildren aged 12-15 years. From April to May 2018, we administered a 15-item questionnaire to children in 15 primary schools, to assess the effects of theoretical and practical cardiopulmonary resuscitation training on their knowledge of cardiopulmonary resuscitation at 1-2 months after training. Data were processed using univariate, bivariate, and multivariate analyses.
A significantly greater level of post-training knowledge was noted in all three equally sized school grade groups (p=0.001). The youngest group (mean age 12.5 years) exhibited the greatest increase in knowledge, with test scores increasing by an average 2.65 (range 0-15) points. Age (p=0.001), body mass index (p=0.037), f12.5 years (seventh graders). Early, compulsory resuscitation training might reduce social barriers to performing resuscitation, which may eventually translate into better post-cardiac arrest outcomes.
Persons with ID most often have incomplete, contradictory and imprecise knowledge of sexuality and sexual intercourse itself. They are not provided with sufficient information on their own body and sexuality, and are often discouraged from and sanctioned for trying to sexually express themselves. Sexual abuse due to low sexual assertiveness is also common.
The principal aim of this study was to establish the presence or absence of sexual activity in adults with ID residing in institutional housing, as well as the level and structure of their knowledge of sexuality, their sexual assertiveness and preparedness to react in a sexually dangerous situation.
The sample consisted of 100 participants with ID residing in institutional housing. The instruments used included the General Sexual Knowledge Questionnaire, What-if test and Hulbert index of sexual assertiveness. Comparative statistics included coefficient of linear correlation and multiple regression analysis.
The results showed that 82% of the participants are sexually active. Most participants admitted to sometimes having sexual intercourse against their wishes as well as to having difficulty asserting themselves. Their knowledge of pregnancy, contraception and sexually transmitted diseases was very low. Female participants and those that reported having sexual intercourse had more sexual knowledge and were also more sexually assertive.
Knowledge of sexuality and sexual assertiveness of persons with ID residing in institutional housing is very low. Additional information on sexuality is necessary, as well as support in learning to express their own desires and to deal with unwanted sexual activity.

Future nurses should possess the knowledge and competences necessary to ensure patient safety. However, little evidence is available on the way in which students learn patient safety-related principles over time. This study explored the progress of a cohort of Italian undergraduate nursing students as they acquired patient safety knowledge and competences from time of enrolment to graduation.
A longitudinal study carried out between 2015 and 2018 enrolled a cohort of 90 nursing students from two Italian Bachelor of Nursing Science Degree Courses at the Udine University, Italy. The students were followed-up on an annual basis and data collection was performed three times at the end of the 1st, 2nd and 3rd years. The validated Italian version of the Professional Education in Patient Safety Survey tool was used to collect data.
At the end of the 1st year, students reported an average 4.19 out of 5 patient safety knowledge acquired in classrooms (CI 95%, 4.11-4.28), which was stable at the end of the 2nd (4.
