RESUMEN
BACKGROUND: Although attending to spiritual and religious needs is part of high quality care of pediatric cancer patients, oncology clinicians may not understand the role of the chaplain, resulting in underutilization of resources and failure to fully integrate the chaplain into the clinical team. We provide a description of what the chaplain does in the care of pediatric oncology patients. METHODS: We conducted a qualitative content analysis of chaplain chart notes over a one-year period on the pediatric oncology service at a freestanding children's hospital. Using criteria designed to capture multiple potential factors in chaplain referral, we selected 30 patients for thematic analysis. RESULTS: In 2016, 166 pediatric patients were diagnosed with cancer and received ongoing care at our institution. From the 30 patients selected, 230 chaplain encounters were documented in the medical chart. Three major themes emerged. (1) The chaplains provided a rich description of spiritual and psychosocial aspects of the patient and family's experience; (2) chaplains provided diverse interventions, both religious and secular in nature; and (3) chaplains provided care within a longitudinal relationship. All three themes depend on the empathic listening by a chaplain. CONCLUSIONS: The chaplains' observations about patient and family beliefs, experiences, and emotional/spiritual states have the potential to inform the interdisciplinary care of the patient. Chaplain documentation provides insight into how spiritual care interventions and close relationships may promote patient and family well-being. In future work, we will explore how to give voice to their insights in caring for pediatric oncology patients.

Conservation of exploited species requires an understanding of both genetic diversity and the dominant structuring forces, particularly near range limits, where climatic variation can drive rapid expansions or contractions of geographic range. Here, we examine population structure and landscape associations in Atlantic salmon (Salmo salar) across a heterogeneous landscape near the northern range limit in Labrador, Canada. Analysis of two amplicon-based data sets containing 101 microsatellites and 376 single nucleotide polymorphisms (SNPs) from 35 locations revealed clear differentiation between populations spawning in rivers flowing into a large marine embayment (Lake Melville) compared to coastal populations. The mechanisms influencing the differentiation of embayment populations were investigated using both multivariate and machine-learning landscape genetic approaches. We identified temperature as the strongest correlate with genetic structure, particularly warm temperature extremes and wider annual temperature ranges. The genomic basis of this divergence was further explored using a subset of locations (n = 17) and a 220K SNP array. SNPs associated with spatial structuring and temperature mapped to a diverse set of genes and molecular pathways, including regulation of gene expression, immune response, and cell development and differentiation. The results spanning molecular marker types and both novel and established methods clearly show climate-associated, fine-scale population structure across an environmental gradient in Atlantic salmon near its range limit in North America, highlighting valuable approaches for predicting population responses to climate change and managing species sustainability.

When females prefer mates with rare phenotypes, sexual selection can maintain rather than deplete genetic variation. However, there is no consensus on why this widespread and frequently observed preference might evolve and persist. We examine the fitness consequences of female preference for rare male color patterns in a natural population of Trinidadian guppies, using a pedigree that spans 10 generations. We demonstrate (i) a rare male reproductive advantage, (ii) that females that mate with rare males gain an indirect fitness advantage through the mating success of their sons, and (iii) the fitness benefit that females accrue through their "sexy sons" evaporates for their grandsons as their phenotype becomes common. Counter to prevailing theory, we show that female preference can be maintained through indirect selection.

CONTEXT: Although religion and spirituality are important to surrogate decision makers, little is known about the role of religion in decision making regarding life-sustaining treatments. OBJECTIVES: To determine the relationships between dimensions of religion and spirituality and medical treatment decisions made by surrogates. METHODS: This prospective observational study enrolled patient/surrogate dyads from three hospitals in one metropolitan area. Eligible patients were 65 years or older and admitted to the medicine or medical intensive care services. Baseline surveys between hospital days 2 and 10 assessed seven dimensions of religion and spirituality. Chart reviews of the electronic medical record and regional health information exchange six months after enrollment identified the use of life-sustaining treatments and hospice for patients who died. RESULTS: There were 291 patient/surrogate dyads. When adjusting for other religious dimensions, demographic, and illness factors, only surrogates' belief in miracles was significantly associated with a lower surrogate preference for do-not-resuscitate status (adjusted odds ratio [aOR] 0.39; 95% CI 0.19, 0.78). Among patients who died, higher surrogate intrinsic religiosity was associated with lower patient receipt of life-sustaining treatments within the last 30 days (aOR 0.66; 95% CI 0.45, 0.97). Belief in miracles (aOR 0.30; 95% CI 0.10, 0.96) and higher intrinsic religiosity (aOR 0.70; 95% CI 0.53, 0.93) were associated with lower hospice utilization. CONCLUSION: Few religious variables are associated with end-of-life preferences or treatment. Belief in miracles and intrinsic religiosity may affect treatment and should be identified and explored with surrogates by trained chaplains or other clinicians with appropriate training.

BACKGROUND: Critically ill adult patients who face medical decisions often delegate others to make important decisions. Those who are authorized to make such decisions are typically family members, friends, or legally authorized representatives, often referred to as surrogates. Making medical decisions on behalf of others produces emotional distress. Spirituality and/or religion provide significant assistance to cope with this distress. We designed this study to assess the role of surrogates' spirituality and religion (S/R) coping resources during and after making medical decisions on behalf of critically ill patients. The study's aim was to understand the role that S/R resources play in coping with the lived experiences and challenges of being a surrogate. METHODS: Semistructured interviews were conducted with 46 surrogates by trained interviewers. These were audio-recorded and transcribed by research staff. Three investigators conducted a thematic analysis of the transcribed interviews. The codes from inter-rater findings were analyzed, and comparisons were made to ensure consistency. RESULTS: The majority (67%) of surrogates endorsed belief in God and a personal practice of religion. Five themes emerged in this study. Personal prayer was demonstrated as the most important coping resource among surrogates who were religious. Trusting in God to be in charge or to provide guidance was also commonly expressed. Supportive relationships from family, friends, and coworkers emerged as a coping resource for all surrogates. Religious and nonreligious surrogates endorsed coping strategies such as painting, coloring, silent reflection, music, recreation, and reading. Some surrogates also shared personal experiences that were transformative as they cared for their ill patients. CONCLUSION: We conclude that surrogates use several S/R and other resources to cope with stress when making decisions for critically ill adult patients. The coping resources identified in this study may guide professional chaplains and other care providers to design a patient-based and outcome-oriented intervention to reduce surrogate stress, improve communication, increase patient and surrogate satisfaction, and increase surrogate integration in patient care. We recommend ensuring that surrogates have S/R resources actively engaged in making medical decisions. Chaplains should be involved before, during, and after medical decision making to assess and address surrogate stress. An interventional research-design project to assess the effect of spiritual care on surrogate coping before, during, and after medical decision making is also recommended.

There are only limited treatments currently available for Motor Neurone Disease, each with modest benefits. However, there is a large amount of research and drug discovery currently underway worldwide. The New Zealand Motor Neurone Disease Registry was established in 2017 to facilitate participation in research and clinical trials, and to aid researchers in planning and recruitment. The NZ MND Registry is an opt in patient registry which collects demographic, contact and clinical data for those who choose to enrol. We report anonymised aggregated data from the first year's enrolment. 12th July 2018, there were 142 participants enrolled in the NZ MND Registry. Participant sex distribution reflects the demographics reported worldwide, but ethnicity is divergent from what is seen in New Zealand overall, with an over-representation of people who identify as New Zealand European. 85.5% of participants are diagnosed with sporadic MND and 6.1% with familial MND. The remainder were participants who have not been diagnosed but have a family history, or positive genetic test for a MND-causing mutation. Levels of disability are reported using ALSFRS-R scores, and show that the majority of participants are within the higher range of the scale. The registry has facilitated entry of patients into three studies to date. The establishment of the NZ MND Registry illustrates a swift launch of a rare disease patient registry. The role of patient registries is an ever changing one, but with clear utility at every point of along the pathway to drug discovery.

In the Intensive Care Unit (ICU), family members experience psychological and spiritual distress as they cope with fear, grief, and medical decisions for patients. The study team developed and pilot tested a semistructured chaplain intervention that included proactive contact and spiritual assessment, interventions, and documentation. An interdisciplinary team developed the intervention, the Spiritual Care Assessment and Intervention (SCAI) Framework. Three chaplains delivered the intervention to surrogates in two ICUs. There were 25 of 73 eligible patient/surrogate dyads enrolled. Surrogates had a mean age of 57.6, were 84% female and 32% African American. The majority (84%) were Protestant. All received at least one chaplain visit and 19 received three visits. All agreed they felt supported by the chaplains, and qualitative comments showed spiritual and emotional support were valued. A semistructured spiritual care intervention for ICU surrogates is feasible and acceptable. Future work is needed to demonstrate the intervention improves outcomes for surrogates and patients.

Individual assignment and genetic mixture analysis are commonly utilized in contemporary wildlife and fisheries management. Although microsatellite loci provide unparalleled numbers of alleles per locus, their use in assignment applications is increasingly limited. However, next-generation sequencing, in conjunction with novel bioinformatic tools, allows large numbers of microsatellite loci to be simultaneously genotyped, presenting new opportunities for individual assignment and genetic mixture analysis. Here, we scanned the published Atlantic salmon genome to identify 706 microsatellite loci, from which we developed a final panel of 101 microsatellites distributed across the genome (average 3.4 loci per chromosome). Using samples from 35 Atlantic salmon populations (n = 1,485 individuals) from coastal Labrador, Canada, a region characterized by low levels of differentiation in this species, this panel identified 844 alleles (average of 8.4 alleles per locus). Simulation-based evaluations of assignment and mixture identification accuracy revealed unprecedented resolution, clearly identifying 26 rivers or groups of rivers spanning 500 km of coastline. This baseline was used to examine the stock composition of 696 individuals harvested in the Labrador Atlantic salmon fishery and revealed that coastal fisheries largely targeted regional groups (<300 km). This work suggests that the development and application of large sequenced microsatellite panels presents great potential for stock resolution in Atlantic salmon and more broadly in other exploited anadromous and marine species.
RESUMEN
megasat is software that enables genotyping of microsatellite loci using next-generation sequencing data. Microsatellites are amplified in large multiplexes, and then sequenced in pooled amplicons. megasat reads sequence files and automatically scores microsatellite genotypes. It uses fuzzy matches to allow for sequencing errors and applies decision rules to account for amplification artefacts, including nontarget amplification products, replication slippage during PCR (amplification stutter) and differential amplification of alleles. An important feature of megasat is the generation of histograms of the length-frequency distributions of amplification products for each locus and each individual. These histograms, analogous to electropherograms traditionally used to score microsatellite genotypes, enable rapid evaluation and editing of automatically scored genotypes. megasat is written in Perl, runs on Windows, Mac OS X and Linux systems, and includes a simple graphical user interface. We demonstrate megasat using data from guppy, Poecilia reticulata. We genotype 1024 guppies at 43 microsatellites per run on an Illumina MiSeq sequencer. We evaluated the accuracy of automatically called genotypes using two methods, based on pedigree and repeat genotyping data, and obtained estimates of mean genotyping error rates of 0.021 and 0.012. In both estimates, three loci accounted for a disproportionate fraction of genotyping errors; conversely, 26 loci were scored with 0-1 detected error (error rate ≤0.007). Our results show that with appropriate selection of loci, automated genotyping of microsatellite loci can be achieved with very high throughput, low genotyping error and very low genotyping costs.
