Background: Irritable bowel syndrome (IBS) and functional dyspepsia (FD) are common disorders of gut-brain interaction (DGBI). The Rome IV criteria are the gold standard for research when diagnosing DGBI. However, bothersomeness, or the degree to which symptoms are distressing or disruptive to a person's daily life, is a potential treatment-seeking motivator that is not assessed by the Rome criteria.

Article Synopsis
  • Organophosphates (OP) are harmful chemicals used in agriculture and warfare, creating a need for effective detection methods that work quickly and are cost-effective, especially for detecting contamination in liquid samples.
  • Current detection methods are only useful in the short term and fail to address long-term contamination risks, highlighting the need for real-time monitoring of OPs in water and soil.
  • This study introduces a transistor-based sensor called MNChem, capable of ultra-sensitive, quantitative detection of diethyl cyanophosphonate (DCNP) in small liquid samples, achieving a detection limit of 100 fg/mL and a wide dynamic range, suggesting it’s suitable for on-site environmental analysis.*

October 2024

Department of Psychology, Faculty of Humanities and Social Sciences, Ben-Gurion University of the Negev, Be'er Sheva, Israel.

Article Synopsis
  • - Identified four distinct clusters of adults with bipolar disorder (BD) based on BD symptoms and perceived cognitive errors, with a hypothesis suggesting that more symptoms and cognitive errors correlate with lower psychological well-being.
  • - The study involved 281 adults aged 19-81, revealing that those with more cognitive failures reported higher levels of both depression and hypo/mania symptoms, leading to lower self-efficacy and life satisfaction.
  • - Contrary to previous research, age differences in cognitive loss were not significant across the clusters, indicating that perceived cognitive errors negatively impact psychological well-being regardless of the participant's age.

Predictive modeling of medication adherence in post myocardial infarction patients: a bayesian approach using beta-regression.

Eur J Prev Cardiol

October 2024

Department of Clinical Biochemistry and Pharmacology Faculty of Health Sciences, Ben-Gurion University of the Negev, PO Box 653, Beer-Sheva 8410501, Israel.

Aims: Predicting medication adherence in post myocardial infarction (MI) patients has the potential to improve patient outcomes. Most adherence prediction models dichotomize adherence metrics and status. This study aims to develop medication adherence prediction models that avoid dichotomizing adherence metrics and to test whether a simplified model including only 90-days adherence data would perform similarly to a full multivariable model.

Article Synopsis
  • The study aimed to evaluate the risk of seizures in patients with Giant Cell Arteritis (GCA) compared to matched controls in Israel.
  • A total of 8,103 GCA patients and 32,412 controls were analyzed, showing that GCA patients had a higher incidence of seizures (15.92 cases per 10,000 person-years) than controls (9.62 per 10,000).
  • The findings indicate that GCA patients have a significantly increased risk of seizures, which is likely related to the inflammatory state associated with GCA, rather than pre-existing conditions like stroke.

October 2024

Department of Chemistry, Ben-Gurion University of the Negev, Beer Sheva 84105, Israel.

Time crystals, a unique nonequilibrium quantum phenomenon with promising applications in current quantum technologies, mark a significant advance in quantum mechanics. Although traditionally studied in atom-cavity and optical lattice systems, pursuing alternative nanoscale platforms for time crystals is crucial. Here we theoretically predict discrete time crystals in a periodically driven molecular magnet array, modeled by a spin-S Heisenberg Hamiltonian with significant quadratic anisotropy, taken with realistic and experimentally relevant physical parameters.

Reconfiguring two shortest paths in a graph means modifying one shortest path to the other by changing one vertex at a time so that all the intermediate paths are also shortest paths. This problem has several natural applications, namely: (a) repaving road networks, (b) rerouting data packets in a synchronous multiprocessing setting, (c) the shipping container stowage problem, and (d) the train marshalling problem. When modelled as graph problems, (a) is the most general case while (b), (c), (d) are restrictions to different graph classes.

Article Synopsis
  • Atypical face perception in individuals with autism has been linked to social challenges, with debates ongoing about whether these deficits are due to perception issues or lack of experiential refinement.
  • A study involving autistic and non-autistic participants revealed that autistic individuals showed less distinction in processing own- and other-race faces, using only the most recently seen faces instead of forming a broader internal representation.
  • These findings suggest that the way autistic individuals process faces differs fundamentally from non-autistics, which may explain their difficulties in face recognition and social interactions.

The variety of possible benzene isomers may provide a fundamental basis for understanding structural and reactivity patterns in organic chemistry. However, the vast majority of these isomers remain unsynthesized, while most of the experimentally known species are only moderately stable. Consequently, there is a high probability that the theoretically proposed isomers would also be barely metastable, a factor that must be taken into account if their creation in the laboratory is sought.
