Published: April 2020

Abstract
Background
Predicting the possibility of severe effects of global warming on animals is important for understanding the ecological consequences of climate change on ecosystem. Spring is the season during which birds have to physiologically prepare for the subsequent breeding period, and unusual spring temperature rising probably becomes a heat stress to the birds which have adapted to the low spring temperature. Therefore, it is necessary to understand the physiological effect of spring warming on the temperate birds.

Methods
Using the activities of blood anti-oxidative enzymes (SOD, CAT, GPx) and the concentrations of serum immunogloblins (IgA, IgY, IgM) as indicators, we compared the anti-oxidative and immune functions of Asian Short-toed Larks (Calandrella cheleensis) captured between 10 and 15 March, 2015 and housed under conditions of 21 °C and 16 °C.

Results
The SOD activities of birds in 21 °C group were significantly lower than those in 16 °C group on all the treatment days. The CAT activities of the birds in 21 °C group were significantly lower than those in 16 °C group on the 1st, 5th, 13th, 17 treatment days. The GPx activities of the birds in 21 °C group were signifthicantly lower than those in 16 °C group on the 1st, 13th and 17th, but significantly higher on the 21st treatment day. The IgA, IgY and IgM concentrations of birds in 21 °C group were significantly lower than those in 16 °C group on all the treatment days.

Conclusions
This study shows that spring temperature rising negatively influences antioxibative and humoral immune functions, which indicates that spring climate warming might reduce the fitness of the temperate passerine birds which have adapted to the low spring temperature.

Abstract
Purpose
Microperimetry (MP) allows for measurement of retinal sensitivity at precise locations and is now commonly employed as a clinical trial endpoint. Test–retest reliability is important when evaluating treatment effects in patients with geographic atrophy (GA). This study aimed to determine the test–retest variability of MP in patients with moderate to severe GA using the MAIA MP device.

Methods
In this prospective study, patients with a confirmed diagnosis of foveal-involving GA were enrolled. Participants performed three MP assessments of a selected eye over two visits with the Macular Integrity Assessment (MAIA) 2 instrument (Centervue, Padova, Italy) utilizing a wide 30° grid, consisting of 93 stimuli (Goldmann III) using a 4-2 representation strategy, encompassing the entire area of GA and beyond. Mean retinal sensitivity (MS) was expressed as an average threshold value (dB) for the entire field tested. Coefficients of Repeatability at a 95% level (CoR95) were calculated for Point Wise Sensitivity (PWS). Fixation stability (FS) was assessed by evaluating the area of an elliptical representation encompassing 95% of the cloud of fixation points (CFP) dataset generated by the MAIA MP, known as the bivariate contour ellipse area (BCEA).

Results
A total of 8 subjects were enrolled (21 tests), with six subjects completing 3 MP assessments. BCVA in these patients ranged from 20/100 to 20/800. The mean area of GA was 18.7 ± 12.3 mm2. The average time to complete one MP assessment was 13 min 9 s and mean BCEA@95% was 38.5 ± 19.3°2. The MS was 14.3 ± 4.5 dB. No significant increase in MS was noted between testing pairs 1&2 and 2&3. The preferred retinal locus was maintained in the same quadrant on successive tests. The mean CoR95 for PWS were similar for testing pairs 1&2 (± 3.50 dB) and 2&3 (± 3.40).

Conclusion
Microperimetry using a wide grid can be reliably performed in a reasonable amount of time in patients with moderate and severe vision loss secondary to GA. There was no learning effect seen between sequential assessments when analyzing MS or PWS. A change of approximately 4 dB in PWS provides a threshold for considering a true change in this patient cohort.
Childlessness and low fertility in context: evidence from a multilevel analysis on 20 European countries
Authors: Brini Elisa 
Published: April 2020

AbstractLow fertility and childlessness have been largely interpreted as being driven by the same mechanisms, although they may be qualitatively different phenomena. The present article discusses this assumption and studies determinants of childlessness by comparing them with determinants of low fertility. Drawing on micro-level data from the European Labour Force Survey (2005–2010) and macro-level data from external data sources, it enters the debate on the micro- and macro-determinants of fertility and childlessness by analysing women who live with or without children when they are 35–39 years old. By means of a series of multilevel models, it discusses the moderating role of the institutional and normative context in the link between individual characteristics and childlessness, and it analyses the extent to which micro- and macro-level determinants of childlessness differ from factors associated with low-fertility. The results indicate that the macro-level factors associated with individual childlessness are similar to those identified in the literature on low fertility. However, interesting differences emerge in how reconciliation and family support policies relate on childlessness and low-fertility across different groups of women. Overall, these findings highlight the importance to study childlessness as a phenomenon on its own, distinguishing its determinants from determinants of (low) fertility.

Published: April 2020

Abstract
Background
Recent reviews of the use and application of implementation frameworks in implementation efforts highlight the limited use of frameworks, despite the value in doing so. As such, this article aims to provide recommendations to enhance the application of implementation frameworks, for implementation researchers, intermediaries, and practitioners.

Discussion
Ideally, an implementation framework, or multiple frameworks should be used prior to and throughout an implementation effort. This includes both in implementation science research studies and in real-world implementation projects. To guide this application, outlined are ten recommendations for using implementation frameworks across the implementation process. The recommendations have been written in the rough chronological order of an implementation effort; however, we understand these may vary depending on the project or context: (1) select a suitable framework(s), (2) establish and maintain community stakeholder engagement and partnerships, (3) define issue and develop research or evaluation questions and hypotheses, (4) develop an implementation mechanistic process model or logic model, (5) select research and evaluation methods (6) determine implementation factors/determinants, (7) select and tailor, or develop, implementation strategy(s), (8) specify implementation outcomes and evaluate implementation, (9) use a framework(s) at micro level to conduct and tailor implementation, and (10) write the proposal and report. Ideally, a framework(s) would be applied to each of the recommendations. For this article, we begin by discussing each recommendation within the context of frameworks broadly, followed by specific examples using the Exploration, Preparation, Implementation, Sustainment (EPIS) framework.

Summary
The use of conceptual and theoretical frameworks provides a foundation from which generalizable implementation knowledge can be advanced. On the contrary, superficial use of frameworks hinders being able to use, learn from, and work sequentially to progress the field. Following the provided ten recommendations, we hope to assist researchers, intermediaries, and practitioners to improve the use of implementation science frameworks.
Barriers and strategies for implementing community-based interventions with minority elders: positive minds-strong bodies

Published: April 2020

Abstract
Background
By 2040, one out of three older adults in the USA are expected to belong to a racial/ethnic minority group. This population has an increased risk of mental and physical disability with significant barriers to access care. Community-based organizations (CBOs) often provide programming to serve minority and immigrant elders. Limited resources and other barriers such as lack of trained staff make it difficult to implement evidence-based interventions (EBIs) in CBOs for long-term adoption. Yet little is known about what factors can facilitate adoption of EBIs in CBOs serving minority elders.

Methods
Positive-Minds–Strong Bodies (PM-SB), an evidence-based intervention offered in four languages, aims to reduce mental and physical disability for minority and immigrant elders through the efforts of community health workers and exercise trainers. The intervention consists of cognitive behavior therapy and exercise training sessions delivered over 6 months. During a recent clinical trial of this intervention, we elicited feedback from CBO staff to determine how best to facilitate the implementation and long-term sustainability of PM-SB within their agencies. We surveyed 30 CBO staff members, held four focus groups, and conducted 20 in-depth interviews to examine staff perspectives and to reveal factors or changes needed to facilitate long-term adoption in prospective CBOs.

Results
Participants reported that staff motivation and implementation could be improved through the following changes: increasing patient compensation for treatment sessions, decreasing levels of organizational accountability, and reducing staff demands embedded in the intervention. Although most staff perceived that PM-SB improved their agency’s ability to address the health and well-being of elders, capacity-building strategies such as a “train-the-trainer” initiative were identified as priorities to address staff turnover for sustainability. Adapting the intervention to get financial reimbursement also emerged as vital.

Conclusions
Augmenting financial incentives, streamlining procedures, and simplifying staff accountability were suggested strategies for facilitating the transition from a disability prevention clinical trial in minority and immigrant elders to a scalable implementation in routine services at CBOs.

Regional analysis of UK primary care prescribing and adult service referrals for young people with attention-deficit hyperactivity disorder: from little to very little
Authors: Cortese Samuele 
Published: April 2020

Summary
Drawing on data from the Clinical Practice Research Datalink, Price et al reported UK regional variations in primary care prescribing and referral rates to adult mental health services for young people with attention-deficit hyperactivity disorder (ADHD) in transition from child and adolescent mental health services. Overall, considering that around 65% of young adults with childhood ADHD present with impairing ADHD symptoms and up to 90% of individuals with ADHD may benefit from ADHD medications, the study by Price et al shows that the rate of appropriate treatment for youngsters in the transition period varies from low to very low across the UK. As such, there is a continuous need for education and training for patients, their families, mental health professionals and commissioners, to eradicate the misconception that, in the majority of the cases, ADHD remits during adolescence and to support the devolvement of appropriate services for the evidence-based management of adult ADHD across the UK.

PURPOSE: The expansion of learning health care systems (LHSs) promises to bolster research and quality improvement endeavors. Stewards of patient data have a duty to respect the preferences of the patients from whom, and for whom, these data are being collected and consolidated. METHODS: We conducted democratic deliberations with a diverse sample of 217 patients treated at 4 sites to assess views about LHSs, using the example of CancerLinQ, a real-world LHS, to stimulate discussion. In small group discussions, participants deliberated about different policies for how to provide information and to seek consent regarding the inclusion of patient data. These discussions were recorded, transcribed, and de-identified for thematic analysis. RESULTS: Of participants, 67% were female, 61% were non-Hispanic Whites, and the mean age was 60 years. Patients' opinions about sharing their data illuminated 2 spectra: trust/distrust and individualism/collectivism. Positions on these spectra influenced the weight placed on 3 priorities: promoting societal altruism, ensuring respect for persons, and protecting themselves. In turn, consideration of these priorities seemed to inform preferences regarding patient choices and system transparency. Most advocated for a policy whereby patients would receive notification and have the opportunity to opt out of including their medical records in the LHS. Participants reasoned that such a policy would balance personal protections and societal welfare. CONCLUSION: System transparency and patient choice are vital if patients are to feel respected and to trust LHS endeavors. Those responsible for LHS implementation should ensure that all patients receive an explanation of their options, together with standardized, understandable, comprehensive materials.

PURPOSE BRCA1 or BRCA2 loss of function results in homologous recombination deficiency (HRD), which is targetable by poly (ADP-ribose) polymerase (PARP) inhibitors and other DNA-damaging agents. In cancers associated with germline BRCA1/2 alterations ( BRCA1/2-associated cancers: breast, ovarian, pancreatic, prostate), BRCA1/2 alterations result in HRD and are biomarkers for PARP inhibitor use. In other (non– BRCA1/2-associated) cancer types, the association between BRCA1/2 alteration and HRD is less clear. METHODS A total of 234,154 tumor samples were sequenced by hybrid capture-based comprehensive genomic profiling. Somatic, germline, and zygosity status was determined computationally. BRCA1/2 alterations were classified as predicted germline/somatic and biallelic/monoallelic. Genome-wide loss of heterozygosity (gLOH) was evaluated as a marker of HRD. RESULTS BRCA1/2 alterations were observed at a 4.7% frequency. BRCA1/2 mutations were predicted germline in 57.4% of BRCA1/2-associated and 37.2% of non– BRCA1/2-associated cancers. The fraction of BRCA1/2-altered cases that were biallelic was 68.7%, with a higher biallelic fraction in BRCA1/2-associated (89.9%) versus non– BRCA1/2-associated cancers (43.6%). Differences in tissue distribution of biallelic BRCA1 versus BRCA2 alterations were noted, including a higher rate of biallelic BRCA2 alteration in prostate cancer. Biallelic BRCA1/2 alteration was observed at a 3.2% frequency ( BRCA1/2-associated cancers, 8.9%; non– BRCA1/2-associated cancers, 1.3%) and > 1% frequency in at least 13 cancer types. Across cancer types, biallelic BRCA1/2 alteration was associated with increased gLOH versus monoallelic or wild-type BRCA1/2; predicted germline or somatic mutations were both associated with elevated gLOH. CONCLUSION Biallelic BRCA1/2 alterations were associated with elevated gLOH in diverse cancer types, including those not traditionally associated with BRCA1/2 cancer syndromes. Biomarker development for PARP inhibitors should integrate methods to distinguish biallelic from monoallelic BRCA1/2 status, and biallelic BRCA1/2 alteration should be broadly evaluated across cancer types as a biomarker for underlying HRD and PARP inhibitor sensitivity.
Terahertz plasma wave localization and velocity control in tapered double-layer graphene heterostructure
Authors: Morozov Mikhail Yu. , Popov Vyacheslav V. 
Published: April 2020

Abstract
Terahertz plasma wave (plasmon) localization and velocity control in tapered heterostructure (taper) with double-layer graphene were numerically studied. We employ a simple rigorous theoretical model to find out the plasmon localization length and energy velocity values along the tapered structure. It is shown that the plasmon decelerates while moving from the taper apex and the deceleration process is accompanied with increase of the plasmon wave localization. While moving along the structure from the taper apex, the plasmon energy velocity as well as the plasmon localization length can become nearly an order of magnitude smaller as compared to the values near the taper apex.
ACTH Infusion Impairs Baroreflex Sensitivity—Implications for Cardiovascular Hypoglycemia-Associated Autonomic Failure

Published: April 2020

AbstractContextHypoglycemia attenuates cardiovascular homeostatic autonomic control. This attenuation, known as the cardiovascular component of hypoglycemia-associated autonomic failure (HAAF), is characterized most notably by decreased baroreflex sensitivity (BRS) that begins during hypoglycemia and persists until at least the next day, despite return to euglycemia. Understanding the mechanisms underlying this reduction in BRS is important because BRS attenuation is associated with increased morbidity and mortality.ObjectiveThe objective of this work is to investigate the role of the adrenocorticotropin (ACTH)-adrenal axis in decreasing BRS. We tested the hypothesis that infusion of ACTH 1–24 (cosyntropin), as compared to placebo, would acutely suppress BRS, and that this decrease in BRS would be present the next day.DesignA double-blind, placebo-controlled, random-order, cross-over study was conducted.SettingThis study took place in a clinical research center.ParticipantsParticipants included healthy men and women.InterventionsInterventions included an intravenous infusion of cosyntropin (70 μg/hour for 2.5 hours in the morning and again in the early afternoon) vs normal saline placebo.Main Outcome MeasuresOutcome measures included BRS during and 16 hours after cosyntropin vs placebo infusions.ResultsCosyntropin infusion attenuated BRS (mm Hg/ms) as compared to placebo (baseline 17.8 ± 1.38 vs 17.0 ± 2.07; during 14.4 ± 1.43 vs 17.3 ± 1.65; and next day 14.8 ± 1.42 vs 18.9 ± 2.04; P &lt; .05, time by treatment, analysis of variance). BRS was decreased during the final 30 minutes of the morning cosyntropin infusion as compared to baseline (P &lt; .01) and remained suppressed the next day (16 hours after afternoon infusion) (P &lt; .025). Placebo infusion did not significantly change BRS. Corrected QT interval was not affected.ConclusionsACTH attenuates BRS, raising the possibility that hypoglycemia-induced increases in ACTH may contribute to the cardiovascular component of HAAF.
Family carers’ perspectives of the Alzheimer Café in Ireland

Published: April 2020

Background:The Alzheimer Café is a psychosocial intervention shown to have benefits for family carers of people with dementia. Family carers of people with dementia experience a period of change across all aspects of their lives following a diagnosis of dementia, requiring the development of new skills and tools to navigate these new landscapes. The objective of this research is to investigate family carers’ perspectives of the Alzheimer Café in Ireland, and to explore how attendance may translate into broader benefits in their lives. This paper will also provide an overview of Alzheimer Café models, which exist internationally.Methods:This is a qualitative study using semi-structured interviews with nine family carers of people with dementia who were currently attending or have previously attended an Alzheimer Café in the preceding six months. The research was conducted in three Alzheimer Café sites in Ireland. Data analysis was conducted using Braun and Clarke’s six step framework for thematic analysis.Results:Community, atmosphere, activity and information were described as core features of the Alzheimer Café in Ireland for family carers. The Alzheimer Café was shown to provide a social outlet which facilitated relationship building within care dyads as well as with other attendees. Several information avenues were identified including broad overviews from guest speakers, attendees’ shared experiences, and specific advice from healthcare professionals.Conclusion:The Alzheimer Café offers strong personal support to family carers of people with dementia. It can also help to build family carers’ capacity to manage new social, environmental and cultural challenges associated with dementia. While it is important the Alzheimer Café is enjoyable, has useful information and is supportive, it is equally important that these features generate sustained improvements for family carers external to the Alzheimer Café.
