Cryptosporidiosis is a diarrheal disease caused by the parasite resulting in over 100,000 deaths annually. Here, we present a structure-activity relationship study of the benzoic acid position (R) of pyrazolo[3,4-]pyrimidine lead SLU-2815 (), an inhibitor of parasite phosphodiesterase PDE1, resulting in the discovery of benzoxaborole SLU-10906 () as a benzoic acid bioisostere. Benzoxaborole is 10-fold more potent than against the parasite in a cell-based infection model (EC = 0.

Article Synopsis
  • FSHD is a muscle-wasting disease caused by the misexpression of the DUX4 transcription factor, leading to progressive muscle weakness starting from facial and shoulder muscles and eventually affecting the lower limbs.
  • The study utilized siRNAs to investigate the role of SIX family transcription factors in regulating DUX4 expression in patient-derived FSHD muscle cells, revealing that SIX1, SIX2, and SIX4 are essential for DUX4 induction during muscle differentiation.
  • Additionally, the research indicated that DUX4 actually downregulates SIX RNA levels, suggesting a negative feedback loop in the regulation of these transcription factors in FSHD contexts.

Facioscapulohumeral muscular dystrophy (FSHD) is a degenerative muscle disease caused by loss of epigenetic silencing and ectopic reactivation of the embryonic double homeobox protein 4 gene (DUX4) in skeletal muscle. The p38 MAP kinase inhibitor losmapimod is currently being tested in FSHD clinical trials due to the finding that p38 inhibition suppresses DUX4 expression in preclinical models. However, the role of p38 in regulating DUX4 at different myogenic stages has not been investigated.

Background And Objective: Hyperkalemia (HK) is an electrolyte disturbance in the concentration of potassium ions (K), whose risk increases in patients with chronic kidney disease (CKD) or heart failure (HF) and/or in patients being treated with renin-angiotensin-aldosterone system inhibitors (RAASi). The new oral K chelators offer a safe and effective treatment to maintain normokalemia in these patients. The objective of the analysis is to estimate the cost-effectiveness of sodium zirconium cyclosilicate (SZC) for the treatment of chronic HK in patients with CKD or HF versus standard treatment (calcium polystyrene sulfonate and lifestyle modifications) from the perspective of the Spanish National Health System.

This work reports the synthesis of FeO (FeO) microparticles using the Pechini method and their use to remove microplastics from tap water. The analysis by electronic microscopy revealed that the FeO microparticles (FeMicroPs) have a porous structure and are formed by interconnected grains with sizes of 80-120 nm. In addition, the X-ray diffraction analysis pointed out that the FeMicroPs are composed of γ- FeO and α- FeO phases.

We show that the planar, charged black hole in asymptotically anti-de Sitter spacetime, dual to the strongly coupled quark-gluon plasma thermal state of large N, SU(N), N=4 super Yang-Mills at finite chemical potential undergoes a third-order phase transition in the grand canonical ensemble to a hairy black hole of type IIB supergravity. The hairy phase is another strongly coupled fluid with a conformal equation of state and can be interpreted as another kind of quark-gluon plasma. This new quark-gluon plasma has less entropy and, therefore, seems to characterize some form of smooth hadronization.

Article Synopsis
  • Follicular lymphoma (FL) is the most common slow-growing non-Hodgkin lymphoma in the U.S. and Europe, but there's limited data from Latin America, particularly Chile.
  • The study involved 722 Chilean patients diagnosed with FL from 2000 to 2019, revealing a median diagnosis age of 62, with many patients presenting advanced disease and a significant number affected by bone marrow involvement.
  • Key findings show that adding rituximab to chemotherapy improves overall survival and response rate, while experiencing POD24 (progression of disease within 24 months) indicates much poorer survival outcomes.

Article Synopsis
  • The study aimed to determine if the initial tumor burden detected at biopsy could indicate the presence of adverse features after radical prostatectomy in patients with ISUP 1 prostate cancer.
  • Conducted across six centers, the research involved analyzing biopsy results where a high tumor burden was defined as having 20% or more positive cores.
  • Results showed no significant correlation between tumor burden at biopsy and the occurrence of adverse features at radical prostatectomy, suggesting this measurement should not be used to exclude patients from active surveillance.

Article Synopsis
  • Deep Learning (DL) methods are increasingly used for supervised learning but face challenges with missing data in datasets.
  • The authors introduce a novel DL architecture that can handle both ignorable and non-ignorable missing data during training, specifically addressing missing not at random (MNAR) situations.
  • Their approach is validated through simulations and a case study on the Bank Marketing dataset, showing that it outperforms existing methods in predicting client subscriptions based on incomplete phone survey data.

We describe in detail a twofold proposal for the creation, organization and sequential development of two bodies responsible for evaluating the efficiency of health technologies and policies in Spain and its possible design. It would constitute a key element in the process of re-organising the National Health System. The first, which could be adopted immediately, would be called the Office for the Evaluation of the Efficiency of Medicines, would be attached to the Spanish Agency for Medicines and Medical Devices as a functionally independent body and limited to evaluating the efficiency of medicines.

Microplastics, particles under 5 mm, pervade aquatic environments, notably in Tarragona's coastal region (NE Iberian Peninsula), hosting a major plastic production complex. To investigate weathering and yellowness impact on plastic pellets toxicity, sea-urchin embryo tests were conducted with pellets from three locations-near the source and at increasing distances. Strikingly, distant samples showed toxicity to invertebrate early stages, contrasting with innocuous results near the production site.

In recent years, research has highlighted the association between increased adipose tissue surrounding the human heart and elevated susceptibility to cardiovascular diseases such as atrial fibrillation and coronary heart disease. However, the manual segmentation of these fat deposits has not been widely implemented in clinical practice due to the substantial workload it entails for medical professionals and the associated costs. Consequently, the demand for more precise and time-efficient quantitative analysis has driven the emergence of novel computational methods for fat segmentation.

State prescription drug monitoring programs (PDMPs) use proprietary, predictive software platforms that deploy algorithms to determine whether a patient is at risk for drug misuse, drug diversion, doctor shopping, or substance use disorder (SUD). Clinical overreliance on PDMP algorithm-generated information and risk scores motivates clinicians to refuse to treat-or to inappropriately treat-vulnerable people based on actual, perceived, or past SUDs, chronic pain conditions, or other disabilities. This essay provides a framework for challenging PDMP algorithmic discrimination as disability discrimination under federal antidiscrimination laws, including a new proposed rule interpreting section 1557 of the Affordable Care Act.
