These findings suggest that HCN4 play a main role in seizure and identify a cAMP-dependent seizure mechanism in TSC and FCDII. Furthermore, the unique expression of HCN4 exclusively in FCM neurons suggests that gene therapy targeting HCN4 might be effective in reducing seizures in FCDII or TSC.Many chemotherapeutic drugs produce double-strand breaks (DSB) on cancer cell DNA, thereby inducing cell death. However, the DNA damage response (DDR) enables cancer cells to overcome DNA damage and escape cell death, often leading to therapeutic resistance and unsuccessful outcomes. It is therefore important to develop inhibitors that target DDR proteins to render cancer cells hypersensitive to DNA damage. Here, we investigated the applicability of PFI-3, a recently developed bromodomain inhibitor specifically targeting the SWI/SNF chromatin remodeler that functions to promote DSB repair, in cancer treatment. We verified that PFI-3 effectively blocks chromatin binding of its target bromodomains and dissociates the corresponding SWI/SNF proteins from chromatin. We then found that, while having little toxicity as a single agent, PFI-3 synergistically sensitizes several human cancer cell lines to DNA damage induced by chemotherapeutic drugs such as doxorubicin. This PFI-3 activity occurs only for the cancer cells that require SWI/SNF for DNA repair. Our mechanism studies show that PFI-3 exerts the DNA damage-sensitizing effect by directly blocking SWI/SNF's chromatin binding, which leads to defects in DSB repair and aberrations in damage checkpoints, eventually resulting in increase of cell death primarily via necrosis and senescence. This work therefore demonstrates the activity of PFI-3 to sensitize cancer cells to DNA damage and its mechanism of action via SWI/SNF targeting, providing an experimental rationale for developing PFI-3 as a sensitizing agent in cancer chemotherapy. IMPLICATIONS This study, revealing the activity of PFI-3 to sensitize cancer cells to chemotherapeutic drugs, provides an experimental rationale for developing this bromodomain inhibitor as a sensitizing agent in cancer chemotherapy. With improvements in survival rates in newborns with congenital heart defects (CHDs), focus has now shifted toward enhancing neurodevelopmental outcomes across their life span. To systematically review the prevalence and extent of motor difficulties in infants, children, and adolescents with CHD requiring open-heart surgery. Data sources included Embase, Medline and the Cumulative Index to Nursing and Allied Health Literature. Original studies published between 1997 and 2019 examining gross and/or fine motor skills in children born with a CHD requiring open-heart surgery were selected. The prevalence of motor impairments and mean scores on standardized motor assessments were extracted. Findings were grouped in 5 categories on the basis of the age of the children. Forty-six original studies were included in this systematic review. The prevalence of mild to severe motor impairments (scores <-1 SD below normative data or controls) across childhood ranged from 12.3% to 68.6%, and prevalence ranged from 0% to 60.0% for severe motor impairments (<-2 SDs). Although our results suggest that the overall prevalence of motor impairments <-1 SD remains rather constant across childhood and adolescence, severe motor impairments (<-2 SDs) appear to be more prevalent in younger children. Variability in sampling and methodology between the reviewed studies is the most important limitation of this review. The results of this review highlight that infants with CHD have an increased risk of motor impairments across infancy, childhood, and adolescence. These findings stress the importance of systematic screening or evaluation of motor skills across childhood and adolescence in children with CHD.The results of this review highlight that infants with CHD have an increased risk of motor impairments across infancy, childhood, and adolescence.

Preterm infants are at risk for hypothermia in the delivery room (DR). Hypothermia and community hospital delivery are factors associated with increased morbidities and mortality in preterm infants. Community hospital providers have less experience with preterm deliveries and thermoregulation methods in the DR. Community hospital DR providers in Indiana completed a cognitive test evaluating preterm infant DR management. A simulation-based team assessment was evaluated by using a scoring tool. After debriefing, the simulation performance was repeated and rescored. Afterward, providers completed a cognitive knowledge posttest. Eleven to eighteen months later, sites were revisited with cognitive knowledge and team simulated scenarios reassessed. Twenty-five community hospitals with >400 multidisciplinary providers participated in the initial study visit. Average pre- and posttest scores were 48.8% and 94.1% respectively ( value <.001). Participants performed an average of 22.8 of 36 scoring items d often and efficiently, critical to resuscitation because delays in thermoregulation can significantly adversely affect outcomes.As the number of living pediatric solid organ transplant (SOT) recipients continues to grow, there is an increased likelihood that primary care providers (PCPs) will encounter pediatric SOT recipients in their practices. In addition, as end-stage organ failure is replaced with chronic medical conditions in transplant recipients, there is a need for a comprehensive approach to their management. PCPs can significantly enhance the care of immunosuppressed hosts by advising parents of safety considerations and avoiding adverse drug interactions. Together with subspecialty providers, PCPs are responsible for ensuring that appropriate vaccinations are given and can play an important role in the diagnosis of infections. Through early recognition of rejection and posttransplant complications, PCPs can minimize morbidity. Growth and development can be optimized through frequent assessments and timely referrals. buy VB124 Adherence to immunosuppressive regimens can be greatly improved through reinforcement at every encounter, particularly among adolescents.
