Carbamazepine (CBZ) intoxication is an important issue in acute poisonings practice. Pathological reflexes, central breathing depression and cardiac disturbances are the characteristic features of carbamazepine poisoning. The clinical picture is variable and does not always correlate with CBZ serum concentration. Controlled-release formulations of CBZ have a delay of over 48h between the time of ingestion and peak serum CBZ concentrations. Peristalsis paralysis makes the extracorporeal elimination a treatment of choice in this case. Unfortunately, the effectiveness of this procedure is not clearly established -the results are often contradictory which makes it difficult to set standards for elimination treatment. In this research we report 2 cases of controlled-release CBZ poisonings. Deterioration in the clinical state characterized mainly by central breathing depression appeared after 51 hrs (patient I) and 74 hrs (patient II) from CBZ ingestion. Charcoal hemoperfusion (HP) improved patients clinical state. During the HP procedure the mean CBZ plasma half-life (T(1/2)) was 6.67 h and 12.66 h. Those values were a few times lower then those measured after the cessation of HP. The mean charcoal column clearances (with blood flow 180 ml/min) were 77.2 and 108.9 ml/min. CBZ pharmacokinetics makes the drug move rapidly between the compartments during the HP. This movement may cause a reduction in CBZ concentrations in receptors' vicinity. Probably this mechanism accounts for the improvement of the patients' clinical state despite low kinetic values of the procedure.

Polylactic Acid Micro/Nanoplastic Exposure Induces Male Reproductive Toxicity by Disrupting Spermatogenesis and Mitochondrial Dysfunction in Mice.

Department of Urology, Peking University First Hospital, Beijing 100034, China.
Although considered an "eco-friendly" biodegradable plastic, polylactic acid (PLA) microplastic (PLA-MP) poses a growing concern for human health, yet its effects on male reproductive function remain underexplored. This study investigated the reproductive toxicity of PLA in male mice and its potential mechanisms. To this end, our in vivo and in vitro experiments demonstrated that after degradation in the digestive system, a significant number of PLA-MP-derived nanoparticles could penetrate the blood-testis barrier (BTB) and localize within the spermatogenic microenvironment.

Background: With the increasing implementation of patient online record access (ORA), various approaches to access to minors' electronic health records have been adopted globally. In Sweden, the current regulatory framework restricts ORA for minors and their guardians when the minor is aged between 13 and 15 years. Families of adolescents with complex health care needs often desire health information to manage their child's care and involve them in their care.

Vaccine Study Center, Northern California Division of Research, Kaiser Permanente, Oakland, CA, United States.
Background: Real-world COVID-19 vaccine effectiveness (VE) studies are investigating exposures of increasing complexity accounting for time since vaccination. These studies require methods that adjust for the confounding that arises when morbidities and demographics are associated with vaccination and the risk of outcome events. Methods based on propensity scores (PS) are well-suited to this when the exposure is dichotomous, but present challenges when the exposure is multinomial.

Background: Evidence-based digital therapeutics represent a new treatment modality in mental health, potentially providing cost-efficient, accessible means of augmenting existing treatments for chronic mental illnesses. CT-155/BI 3972080 is a prescription digital therapeutic under development as an adjunct to standard of care treatments for patients 18 years of age and older with experiential negative symptoms (ENS) of schizophrenia. Individual components of CT-155/BI 3972080 are designed based on the underlying principles of face-to-face treatment.

Background: Congenital heart disease (CHD) is a birth defect of the heart that requires long-term care and often leads to additional health complications. Effective educational strategies are essential for improving health literacy and care outcomes. Despite affecting around 40,000 children annually in the United States, there is a gap in understanding children's health literacy, parental educational burdens, and the efficiency of health care providers in delivering education.
