RESUMEN
BACKGROUND: Expanded termination of pregnancy (TOP) was regulated in Ireland in December 2018 and services began within the Irish healthcare system in January 2019. METHODS: An audit was performed of all attendances at a newly established TOP clinic, for pregnancies <12 weeks, over a twelve month period. RESULTS: Sixty-six women were seen in the clinic; 13 underwent medical TOP, 22 underwent surgical TOP, 2 miscarriages, 20 retained products following termination in primary care and 3 were beyond the 12 week limit. CONCLUSIONS: In an age where TOP clinics are under threat, we have demonstrated the successful successfully introduction safe and effective person centred termination services within primary and secondary care. This requires a focus on women's health with timely care can provided by dedicated nurse specialists and clinicians.

INTRODUCTION: Community-academic partnerships (CAPs) aim to improve neighborhood population health. Though measuring the impact of partnership activities at a population level can be difficult, evaluating indicators of wellbeing may increase understanding of how communities benefit from CAPs. This study examined child health indicators over time in two low-income, predominantly Black/African American and Hispanic communities where partnerships between an academic child development center and community coalitions were formed with the intention of improving child well-being. METHODS: Trends in three child wellbeing indicators (graduation rates, kindergarten readiness, and proportion of youth in school and/or employed) were compared between two CAP communities and several neighboring comparison communities. Data between 2011 and 2017 were analyzed to calculate percent change from baseline and mapped using ArcGIS to visualize trends by zip code. Proportions of youth meeting benchmarks were also determined. RESULTS: Kindergarten readiness and high-school graduation rates improved in CAP communities but not in geographically proximal and socioeconomically similar comparison communities. No improvements were found in the proportion of youth in school or employed. DISCUSSION: This study revealed population-level indicators improved over time in CAP communities. Because community-level child health and wellbeing are influenced by many factors, this correlation is not proof of a causal relationship. Assessing population level indicators can nonetheless provide insight into the benefit of CAPs, and the commitment to monitoring such outcomes can itself advance how academic and community partners plan activities and set long-term goals.

This roadmap on Nanotechnology for Catalysis and Solar Energy Conversion focuses on the application of nanotechnology in addressing the current challenges of energy conversion: 'high efficiency, stability, safety, and the potential for low-cost/scalable manufacturing' to quote from the contributed article by Nathan Lewis. This roadmap focuses on solar-to-fuel conversion, solar water splitting, solar photovoltaics and bio-catalysis. It includes dye-sensitized solar cells (DSSCs), perovskite solar cells, and organic photovoltaics. Smart engineering of colloidal quantum materials and nanostructured electrodes will improve solar-to-fuel conversion efficiency, as described in the articles by Waiskopf and Banin and Meyer. Semiconductor nanoparticles will also improve solar energy conversion efficiency, as discussed by Boschloo et al in their article on DSSCs. Perovskite solar cells have advanced rapidly in recent years, including new ideas on 2D and 3D hybrid halide perovskites, as described by Spanopoulos et al 'Next generation' solar cells using multiple exciton generation (MEG) from hot carriers, described in the article by Nozik and Beard, could lead to remarkable improvement in photovoltaic efficiency by using quantization effects in semiconductor nanostructures (quantum dots, wires or wells). These challenges will not be met without simultaneous improvement in nanoscale characterization methods. Terahertz spectroscopy, discussed in the article by Milot et al is one example of a method that is overcoming the difficulties associated with nanoscale materials characterization by avoiding electrical contacts to nanoparticles, allowing characterization during device operation, and enabling characterization of a single nanoparticle. Besides experimental advances, computational science is also meeting the challenges of nanomaterials synthesis. The article by Kohlstedt and Schatz discusses the computational frameworks being used to predict structure-property relationships in materials and devices, including machine learning methods, with an emphasis on organic photovoltaics. The contribution by Megarity and Armstrong presents the 'electrochemical leaf' for improvements in electrochemistry and beyond. In addition, biohybrid approaches can take advantage of efficient and specific enzyme catalysts. These articles present the nanoscience and technology at the forefront of renewable energy development that will have significant benefits to society.
RESUMEN
The crystal structure of the Escherichia coli O2-sensitive C19G [NiFe]-hydrogenase-1 variant shows that the mutation results in a novel FeS cluster, proximal to the Ni-Fe active site. While the proximal cluster of the native O2-tolerant enzyme can transfer two electrons to that site, EPR spectroscopy shows that the modified cluster can transfer only one electron, this shortfall coinciding with O2 sensitivity. Computational studies on electron transfer help to explain how the structural and redox properties of the novel FeS cluster modulate the observed phenotype.

We describe an approach to generating and verifying well-defined redox states in metalloprotein single crystals by combining electrochemical control with synchrotron infrared microspectroscopic imaging. For NiFe hydrogenase 1 from Escherichia coli we demonstrate fully reversible and uniform electrochemical reduction from the oxidised inactive to the fully reduced state, and temporally resolve steps during this reduction.

Objective: To summarize compensation results from the 2015 Society of Pediatric Psychology (SPP) Workforce Survey and identify factors related to compensation of pediatric psychologists. Methods: All full members of SPP ( n = 1,314) received the online Workforce Survey; 404 (32%) were returned with usable data. The survey assessed salary, benefits, and other income sources. The relationship between demographic and employment-related factors and overall compensation was explored. Results: Academic rank, level of administrative responsibility, and cost of living index of employment location were associated with compensation. Compensation did not vary by gender; however, women were disproportionately represented at the assistant and associate professor level. Conclusions: Compensation of pediatric psychologists is related to multiple factors. Longitudinal administration of the Workforce Survey is needed to determine changes in compensation and career advancement for this profession over time. Strategies to increase the response rate of future Workforce Surveys are discussed.

OBJECTIVE: This study was conducted to determine the relationship of frontal lobe cortical thickness and basal ganglia volumes to measures of cognition in adults with sickle cell anemia (SCA). METHODS: Participants included 120 adults with SCA with no history of neurologic dysfunction and 33 healthy controls (HCs). Participants were enrolled at 12 medical center sites, and raters were blinded to diagnostic group. We hypothesized that individuals with SCA would exhibit reductions in frontal lobe cortex thickness and reduced basal ganglia and thalamus volumes compared with HCs and that these structural brain abnormalities would be associated with measures of cognitive functioning (Wechsler Adult Intelligence Scale, 3rd edition). RESULTS: After adjusting for age, sex, education level, and intracranial volume, participants with SCA exhibited thinner frontal lobe cortex (t = -2.99, p = 0.003) and reduced basal ganglia and thalamus volumes compared with HCs (t = -3.95, p < 0.001). Reduced volume of the basal ganglia and thalamus was significantly associated with lower Performance IQ (model estimate = 3.75, p = 0.004) as well as lower Perceptual Organization (model estimate = 1.44, p = 0.007) and Working Memory scores (model estimate = 1.37, p = 0.015). Frontal lobe cortex thickness was not significantly associated with any cognitive measures. CONCLUSIONS: Our findings suggest that basal ganglia and thalamus abnormalities may represent a particularly salient contributor to cognitive dysfunction in adults with SCA.

Clinicians and researchers need tools for accurate early assessment of children's acute stress reactions and acute stress disorder (ASD). There is a particular need for independently validated Spanish-language measures. The current study reports on 2 measures of child acute stress (a self-report checklist and a semistructured interview), describing the development of the Spanish version of each measure and psychometric evaluation of both the Spanish and English versions. Children between the ages of 8 to 17 years who had experienced a recent traumatic event completed study measures in Spanish (n = 225) or in English (n = 254). Results provide support for reliability (internal consistency of the measures in both languages ranged from .83 to .89; cross-language reliability of the checklist was .93) and for convergent validity (with later PTSD symptoms, and with concurrent anxiety symptoms). Comparing checklist and interview results revealed a strong association between severity scores within the Spanish and English samples. Differences between the checklist and interview in evaluating the presence of ASD appear to be linked to different content coverage for dissociation symptoms. Future studies should further assess the impact of differing assessment modes, content coverage, and the use of these measures in children with diverse types of acute trauma exposure in English- and Spanish-speaking children.

PURPOSE: Assess the intellectual and academic outcomes as well as risk factors associated with treatment for average-risk medulloblastoma in childhood using 23.4 Gy of craniospinal radiotherapy plus adjuvant chemotherapy. METHODS: From an overall sample of 379 enrolled in the parent study (COG A9961), 110 patients received a total of 192 assessments over more than 5 years with standardized IQ and academic achievement tests. Random coefficient models of the various outcomes were developed that incorporated covariates including chemotherapy regimen, age at diagnosis, sex, initial Full Scale IQ, and mutism. RESULTS: Participants in this study were found to be comparable to the overall sample in all demographic, disease, and treatment factors, except there were more gross total resections in the subsample undergoing intellectual and academic assessment. Major findings include significant decline in both intellectual and academic domains over time that were greater in children who were younger at diagnosis and had higher initial intelligence test scores. Children with mutism were at higher risk for initial effects on intelligence. No effects of sex were found. CONCLUSION: These results show progressive decline over several years post-treatment in standardized intellectual and academic scores. Despite recent improvements in therapies for these children, most notably a decrease dose of craniospinal radiation, they remain at risk. The pursuit of less toxic treatments, particularly for younger children, should continue. Neuropsychological surveillance should be routine at centers treating children with brain tumors.

BACKGROUND: Neurocognitive impairment occurs in children and adults with sickle cell anemia, but little is known about neurodevelopment in very young children. We examined the neurodevelopmental status of infants participating in the Pediatric Hydroxyurea Phase III Clinical Trial (Baby Hug) to determine relationships with age, cerebral blood flow velocity, and hemoglobin concentration. METHODS: Standardized measures of infant neurodevelopment were administered to 193 infants with hemoglobin SS or hemoglobin S-ß(0) thalassemia between 7 and 18 months of age at the time of their baseline evaluation. Associations between neurodevelopmental scores and age, family income, parent education, hemoglobin concentration, and transcranial Doppler velocity were examined. RESULTS: Mean functioning on the baseline neurodevelopment scales was in the average range. There were no mental development scores <70 (impaired); 22 children had scores in the clinically significant range, 11 with impaired psychomotor scores and 11 with problematic behavior rating scores. Significantly poorer performance was observed with older age at baseline. Behavior rating scores were an average of 2.82 percentile points lower per month of age, with similar patterns observed with parent report using adaptive behavior scales. Parent-reported functional abilities and hemoglobin were negatively associated with higher transcranial Doppler velocities. CONCLUSIONS: Whereas overall functioning was in the normal range, behavioral and adaptive function was poorer with older age, even in this very young group of children. Explanatory mechanisms for this association between poorer developmental function and older age need to be identified.

Youth infected with HIV at birth often have sleep disturbances, neurocognitive deficits, and abnormal psychosocial function which are associated with and possibly resulted from elevated blood cytokine levels that may lead to a decreased quality of life. To identify molecular pathways that might be associated with these disorders, we evaluated 38 HIV-infected and 35 uninfected subjects over 18-months for intracellular cytokine levels, sleep patterns and duration of sleep, and neurodevelopmental abilities. HIV infection was significantly associated with alterations of intracellular pro-inflammatory cytokines (TNF-α, IFN-γ, IL-12), sleep factors (total time asleep and daytime sleep patterns), and neurocognitive factors (parent and patient reported problems with socio-emotional, behavioral, and executive functions; working memory-mental fatigue; verbal memory; and sustained concentration and vigilance. By better defining the relationships between HIV infection, sleep disturbances, and poor psychosocial behavior and neurocognition, it may be possible to provide targeted pharmacologic and procedural interventions to improve these debilitating conditions.

PURPOSE: Cancer and its treatments can impair cognitive function, especially memory, leading to diminished quality of life. Prevalence studies of cancer treatment-related memory impairment have not been conducted in the adult-onset cancer population. METHODS: To determine the prevalence of self-reported memory (SRM) problems in people with and without a history of cancer, we analyzed data from a large, nationally representative sample of the civilian, noninstitutionalized US population. Participants answered the yes-or-no question, "Are you limited in any way because of difficulty remembering or because you experience periods of confusion?" Age, sex, race/ethnicity, education, poverty, and general health were controlled. RESULTS: The sample (N = 9,819) consisted of 4,862 men and 4,957 women age 40 years and older. There were 1,938 blacks, 5,552 whites, 1,998 Hispanics, and 331 participants categorized as other race/multiracial. Of these, 1,305 reported a history of cancer; 8,514 did not. Memory problems were self-reported more often by participants with a history of cancer (14%) than by those without (8%). Having had cancer was independently associated with SRM impairment (adjusted odds ratio, 1.4; 95% CI, 1.08 to 1.83). Other predictors of memory impairment were age, lower education, lower income, and poorer general health (P < .01 for all). Participants with cancer had a 40% greater likelihood of reporting memory problems relative to those without cancer. CONCLUSION: Cancer history independently predicted SRM impairment. Prevalence of SRM impairment in people with a history of cancer/cancer treatment is substantial and increasing. Health care providers should assess and be ready to treat memory impairment in patients with a history of cancer.
