Cell-to-cell heterogeneity drives host-virus coexistence in a bloom-forming alga.

Algal blooms drive global biogeochemical cycles of key nutrients and serve as hotspots for biological interactions in the ocean. The massive blooms of the cosmopolitan coccolithophore Emiliania huxleyi are often infected by the lytic E. huxleyi virus, which is a major mortality agent triggering bloom demise.

Recommendations for Providing Medication Adherence Support After Pediatric Hematopoietic Stem Cell Transplant: Caregivers' Lived Experience.

Medication adherence is challenging after pediatric hematopoietic stem cell transplant (HCT), particularly after hospital discharge. Post-HCT medication adherence is important to manage morbidity and mortality risk. Designing interventions that are effective and acceptable to caregivers is key to improving post-HCT medication adherence.

Pediatric Hematopoietic Stem Cell Transplant Medication Adherence Facilitators and Strategies: A Qualitative Study.

Objective: Taking medications as prescribed after hematopoietic stem cell transplant (HCT) is key for ensuring children's survival; however, suboptimal medication adherence is common. Development of evidence-based interventions to improve medication adherence post-HCT is contingent upon understanding what adherence facilitators (i.e.

Molecular characterization of thioester-containing proteins in and their differential gene expression upon exposure.

Schistosomiasis is a disease caused by trematode parasites of the genus that affects approximately 200 million people worldwide. Schistosomiasis has been a persistent problem in endemic areas as there is no vaccine available, currently used anti-helmintic medications do not prevent reinfection, and most concerning, drug resistance has been documented in laboratory and field isolates. Thus, alternative approaches to curtail this human disease are warranted.

Caregivers' Experience of Medication Adherence Barriers during Pediatric Hematopoietic Stem Cell Transplant: A Qualitative Study.

Objective: Medications are critical for reducing morbidity and mortality risk in pediatric hematopoietic stem cell transplant (HCT). Nonetheless, medication adherence is suboptimal in this population. Identifying and managing barriers to medication management (i.

Family Adjustment to Pediatric Hematopoietic Stem Cell Transplant During COVID-19.

Objective: The COVID-19 pandemic has been difficult for families across the world due to fears about infection risk, increased social isolation, and significant changes in family roles and routines. Families with a child undergoing pediatric hematopoietic stem cell transplant (HCT) may be at even greater risk for poor adjustment during COVID-19 given their child's increased risk for infection. The purpose of the current study was to qualitatively examine the impact of COVID-19 on family adjustment during pediatric HCT to inform clinical care.

Mobile health use predicts self-efficacy and self-management in adolescents with sickle cell disease.

Sickle cell disease (SCD) is associated with significant health challenges that often worsen during adolescence. Living with SCD requires a substantial amount of self-management and mobile health (mHealth) holds considerable promise for assessing and changing behaviors to improve health outcomes. We integrated a mobile app as an adjunct to a group intervention (SCThrive) and hypothesized that more engagement with the mHealth app would increase self-management and self-efficacy for adolescents and young adults (AYA) with SCD.

Gender Differences in Grant Submissions across Science and Engineering Fields at the NSF.

There has been great growth in women's participation in the US academic doctoral workforce, but underrepresentation remains in all science and engineering fields, especially at high academic ranks. We obtained estimates of the numbers of professorial women and men in fields likely to seek funding from the National Science Foundation and aligned those numbers with each of six research directorates to investigate temporal trends in submission patterns. We found that women are as likely to be funded as men, but the percentage of women submitting proposals was less than expected in every field but engineering.

The impact of pediatric hematopoietic stem cell transplant timing and psychosocial factors on family and caregiver adjustment.

Background: The impact of pediatric hematopoietic stem cell transplant (HCT) on family functioning varies, but little is known about how the timing of HCT in children's treatment course contributes to this variability. This study examines how preexisting child, sibling, and family problems, the length of time between diagnosis to HCT, and children's age at HCT are associated with family and caregiver functioning.

Procedure: Caregivers (n = 140) of children (≤18 years old) scheduled to undergo their first HCT completed the Psychological Assessment Tool-HCT and the Impact on Family Scale.

Implementation of the Psychosocial Standards for Caregiver Mental Health Within a Pediatric Hematology/Oncology Program.

The assessment of mental health needs and access to appropriate interventions for parents and caregivers is one of 15 evidence-based standards for the psychosocial care of children with cancer and their families. The objectives of this paper are to describe one program's approach to meeting this standard in oncologic, hematologic, and immunologic populations and outline key ethical, regulatory, and logistical considerations in providing mental health services to caregivers in a pediatric medical setting. A description of the Caregiver Mental Health Program (CMHP) is provided along with a case example to illustrate key considerations, including multiple family members needing care, access to psychiatric services, scope of treatment, confidentiality and privacy, and logistics.

A psychosocial clinical care pathway for pediatric hematopoietic stem cell transplantation.

Objective: Currently, no evidence-based psychosocial clinical care pathways (PCCP) exist to triage psychosocial risk levels and guide delivery of psychosocial care to youth receiving a hematopoietic stem cell transplantation (HCT) and their families. The purpose of this paper is to describe the use of qualitative research methodologies to develop PCCP in pediatric HCT consistent with the Standards for Psychosocial Care developed for children with cancer.

Methods: We previously used qualitative methodologies to interview parents to identify four principles to inform the development of PCCPs.

Implementing monitoring triggers and matching of triggered and control sites in the TEMPER study: a description and evaluation of a triggered monitoring management system.

Background: Triggered monitoring in clinical trials is a risk-based monitoring approach where triggers (centrally monitored, predefined key risk and performance indicators) drive the extent, timing, and frequency of monitoring visits. The TEMPER study used a prospective, matched-pair design to evaluate the use of a triggered monitoring strategy, comparing findings from triggered monitoring visits with those from matched control sites. To facilitate this study, we developed a bespoke risk-based monitoring system: the TEMPER Management System.

Screening for Family Psychosocial Risk in Pediatric Hematopoietic Stem Cell Transplantation with the Psychosocial Assessment Tool.

Family psychosocial risk screening is an important initial step in delivering evidence-based care in hematopoietic stem cell transplantation (HCT). Establishing an evidence-based screening approach that is acceptable, reliable, and valid is an essential step in psychosocial care delivery. This is a 3-institution multimethod study.

Triggered or routine site monitoring visits for randomised controlled trials: results of TEMPER, a prospective, matched-pair study.

Background/aims: In multi-site clinical trials, where trial data and conduct are scrutinised centrally with pre-specified triggers for visits to sites, targeted monitoring may be an efficient way to prioritise on-site monitoring. This approach is widely used in academic trials, but has never been formally evaluated.

Methods: TEMPER assessed the ability of targeted monitoring, as used in three ongoing phase III randomised multi-site oncology trials, to distinguish sites at which higher and lower rates of protocol and/or Good Clinical Practice violations would be found during site visits.

Earlier Pediatric Psychology Consultation Predicts Lower Stem Cell Transplantation Hospital Costs.

Objective: The purpose of this study was to examine the hypothesis that earlier time to psychology consultation would predict lower costs for the initial stem cell transplant (SCT) hospitalization among patients receiving care at a children's hospital.

Methods: A retrospective medical record review identified 75 patients (ages 0-32 years) with one or more visits by a licensed clinical psychologist during the initial SCT hospitalization from 2010 to 2014. Demographic and clinical variables were obtained from the electronic medical record and hospitalization costs were obtained from patient billing records.

Development and evaluation of iManage: A self-management app co-designed by adolescents with sickle cell disease.

Background: Adolescents and young adults (AYAs) with sickle cell disease (SCD) are a vulnerable population with high risk of morbidity that could be decreased with effective self-management. Previous research suggests that mobile applications (apps) may facilitate AYA engagement in health-promoting behaviors. The objectives of this study were: (i) describe Internet access and use in AYA with SCD; (ii) identify barriers for self-management in this population; (iii) collaborate with AYA to co-design a mobile app that would minimize barriers; and (iv) evaluate the feasibility and acceptability of the app.

Implementation of a Process for Initial Transcranial Doppler Ultrasonography in Children With Sickle Cell Anemia.

Stroke, a devastating complication of sickle cell anemia (SCA), can cause irreversible brain injury with physical and cognitive deficits. Transcranial Doppler ultrasonography (TCD) is a non-invasive tool for identifying children with SCA at highest risk of stroke. National guidelines recommend that TCD screening begin at age 2 years, yet there is research to suggest less than half of young children undergo screening.
