RESUMO

BACKGROUND: Complicated grief involves the experience of grief-related symptoms at a time, and severity, beyond which could be considered adaptive, while persistent complex bereavement disorder (PCBD) has been identified as a condition that requires further study in the typical population. The aims of this study are to (1) explore the symptoms of complicated grief associated with parental bereavement as self-reported by adults with intellectual disabilities (IDs) who have experienced a parental bereavement and (2) conduct an initial examination of how the existing criteria for PCBD apply to this group. METHODS: This study uses a comparative group design, assessing self and staff (proxy) reports for a group of parentally bereaved individuals and a matched group of non-bereaved individuals using the Complicated Grief Questionnaire - ID Self-Report. Participants were 46 individuals with ID, 30 (65%) of whom who had experienced a parental bereavement within the previous 2 years. The age range was 23-67 years (mean = 43.8; SD = 10.3). RESULTS: The results highlight the presence of a range of symptoms of complicated grief in individuals' self-reports, although there was some evidence that separation distress-related symptoms were more apparent. An analysis of individual symptoms showed patterns of higher reports among the bereaved group as would be expected. Comparing staff and self-reports, key criteria showed higher levels in self-reports among the bereaved group. CONCLUSIONS: This study has demonstrated the capacity of people with ID to self-report personal experience of symptoms of complicated grief, when appropriate and accessible assessment tools are used. Some symptoms were more evident among bereaved individuals (compared with non-bereaved participants), and they tended to be from separation distress criteria. This may indicate the relevance of these symptoms for people with ID and question the existing criteria for PCBD in this population, which may have clinical implications for supporting people with ID experiencing a more complicated bereavement response.

RESUMO

How has evolution led to the variation in behavioural phenotypes (personalities) in a population? Knowledge of whether personality is heritable, and to what degree it is influenced by the social environment, is crucial to understanding its evolutionary significance, yet few estimates are available from natural populations. We tracked three behavioural traits during different life-history stages in a pedigreed population of wild house sparrows. Using a quantitative genetic approach, we demonstrated heritability in adult exploration, and in nestling activity after accounting for fixed effects, but not in adult boldness. We did not detect maternal effects on any traits, but we did detect a social brood effect on nestling activity. Boldness, exploration and nestling activity in this population did not form a behavioural syndrome, suggesting that selection could act independently on these behavioural traits in this species, although we found no consistent support for phenotypic selection on these traits. Our work shows that repeatable behaviours can vary in their heritability and that social context influences personality traits. Future efforts could separate whether personality traits differ in heritability because they have served specific functional roles in the evolution of the phenotype or because our concept of personality and the stability of behaviour needs to be revised.

RESUMO

Understanding how species have replaced each other in the past is important to predicting future species turnover. While past species replacement is difficult to detect after the fact, the process may be inferred from present-day distribution patterns. Species with abutting ranges sometimes show a characteristic distribution pattern, where a section of one species range is enveloped by that of the other. Such an enclave could indicate past species replacement: when a species is partly supplanted by a competitor, but a population endures locally while the invading species moves around and past it, an enclave forms. If the two species hybridize and backcross, the receding species is predicted to leave genetic traces within the expanding one under a scenario of species replacement. By screening dozens of genes in hybridizing crested newts, we uncover genetic remnants of the ancestral species, now inhabiting an enclave, in the range of the surrounding invading species. This independent genetic evidence supports the past distribution dynamics we predicted from the enclave. We suggest that enclaves provide a valuable tool in understanding historical species replacement, which is important because a major conservation concern arising from anthropogenic climate change is increased species replacement in the future.

RESUMO

Multiple Sclerosis (MS) is a neurological condition driven in part by immune cells from the peripheral circulation, the targets for current successful therapies. The autoimmune and MS risk gene ZMIZ1 is underexpressed in blood in people with MS. We show that, from three independent sets of transcriptomic data, expression of ZMIZ1 is tightly correlated with that of hundreds of other genes. Further we show expression is partially heritable (heritability 0.26), relatively stable over time, predominantly in plasmacytoid dendritic cells and non-classical monocytes, and that levels of ZMIZ1 protein expression are reduced in MS. ZMIZ1 gene expression is increased in response to calcipotriol (1,25 Vitamin D3) (p < 0.0003) and associated with Epstein Barr Virus (EBV) EBNA-1 antibody titre (p < 0.004). MS therapies fingolimod and dimethyl fumarate altered blood ZMIZ1 gene expression compared to untreated MS. The phenotype indicates susceptibility to MS, and may correspond with clinical response and represent a novel clinical target.

RESUMO

Reproductive success is associated with age in many taxa, increasing in early life followed by reproductive senescence. In socially monogamous but genetically polygamous species, this generates the interesting possibility of differential trajectories of within-pair and extra-pair siring success with age in males. We investigate these relationships simultaneously using within-individual analyses with 13 years of data from an insular house sparrow (Passer domesticus) population. As expected, we found that both within- and extra-pair paternity success increased with age, followed by a senescence-like decline. However, the age trajectories of within- and extra-pair paternity successes differed significantly, with the extra-pair paternity success increasing faster, although not significantly, in early life, and showing a delayed decline by 1.5 years on average later in life compared to within-pair paternity success. These different trajectories indicate that the two alternative mating tactics should have age-dependent pay-offs. Males may partition their reproductive effort between within- and extra-pair matings depending on their current age to reap the maximal combined benefit from both strategies. The interplay between these mating strategies and age-specific mortality may explain the variation in rates of extra-pair paternity observed within and between species.

RESUMO

In socially monogamous species, individuals can use extra-pair paternity and offspring sex allocation as adaptive strategies to ameliorate costs of genetic incompatibility with their partner. Previous studies on domesticated Gouldian finches (Erythrura gouldiae) demonstrated a genetic incompatibility between head colour morphs, the effects of which are more severe in female offspring. Domesticated females use differential sex allocation, and extra-pair paternity with males of compatible head colour, to reduce fitness costs associated with incompatibility in mixed-morph pairings. However, laboratory studies are an oversimplification of the complex ecological factors experienced in the wild and may only reflect the biology of a domesticated species. This study aimed to examine the patterns of parentage and sex ratio bias with respect to colour pairing combinations in a wild population of the Gouldian finch. We utilized a novel PCR assay that allowed us to genotype the morph of offspring before the morph phenotype develops and to explore bias in morph paternity and selection at the nest. Contrary to previous findings in the laboratory, we found no effect of pairing combinations on patterns of extra-pair paternity, offspring sex ratio or selection on morphs in nestlings. In the wild, the effect of morph incompatibility is likely much smaller, or absent, than was observed in the domesticated birds. Furthermore, the previously studied domesticated population is genetically differentiated from the wild population, consistent with the effects of domestication. It is possible that the domestication process fostered the emergence (or enhancement) of incompatibility between colour morphs previously demonstrated in the laboratory.

RESUMO

The aim of this multinational retrospective cohort study, conducted at academic and community oncology centres, was to describe real-world treatment patterns for patients with a confirmed diagnosis of advanced/metastatic (stage IIIB/IV) non-small cell lung cancer (NSCLC) who initiated first-line systemic therapy from January 2011 through June 2014. The study included 1265 patients in Italy, Spain, Germany, Australia, Korea, Taiwan and Brazil. The proportion of patients with squamous versus non-squamous NSCLC was approximately 20% versus 75%, and associated patient demographic characteristics were similar in all countries, excepting race. Patients with squamous NSCLC were predominantly male and current/ex-smokers. Biomarker tests were performed for the majority of patients with non-squamous NSCLC, ranging from 54% (Brazil) to 91% in Taiwan, where, of those tested, 68% with non-squamous NSCLC had positive epidermal growth factor receptor (EGFR)-mutation status; in other countries the EGFR-positive percentages ranged from 17% (Spain/Brazil) to 40% (Korea). Platinum-based regimens were the most common first-line therapy in all countries except Taiwan, where gefitinib was the most common first-line agent. Median overall survival ranged from 9.3 months (Brazil) to 25.5 months (Taiwan). The diagnostic and treatment patterns recorded in this study were heterogeneous but largely in line with NSCLC guidelines during the study period.

RESUMO

Chronic hepatitis C is associated with health-related quality of life and cognitive impairments, even in mild disease. Recent evidence demonstrating hepatitis C virus (HCV) neurotropism has strengthened a neuropathophysiological hypothesis. However, sample heterogeneity confounds study outcomes. A uniquely homogeneous cohort of Irish women, following an iatrogenic HCV outbreak, offers a rare opportunity to control for HCV chronicity and the virus' purported impact on quality of life and cognition. A multi site, three-group, cross-sectional design was employed. Noncirrhotic, iatrogenically infected women, developing either acute or chronic infection, were recruited from prospective tertiary-care liver clinics and the community. Well-matched healthy controls were also recruited. All participants completed a psychosocial survey and were invited to undergo a comprehensive neuropsychological test battery. Significantly distressed psychosocial symptom profiles were observed in those with an iatrogenic HCV exposure history, which was independent of viral chronicity. Chronic and cleared HCV cohorts were not differentiated from each other. Two distinct subgroups, demarcated along 'impaired' vs 'nonimpaired' quality-of-life reports, were clearly identified and logistic regression analysis identified depressed mood and cognitive fatigue, rather than viral status, as statistically significant predictors of group membership. Compared with matched controls, significant cognitive impairments were not observed in either HCV cohort. Our findings provide strong evidence of nonviral factors accounting for quality of life impairment in chronic HCV and they also appear to question existing reports of cognitive dysfunction in mild disease. Depressed mood and cognitive fatigue appear to be critical psychosocial mediators of reduced quality-of-life and we hypothesize that metabolite abnormalities reported in HCV samples may also be confounded by these factors, given the associated literature.

RESUMO

Colour polymorphism is known to facilitate speciation but the genetic basis of animal pigmentation and how colour polymorphisms contribute to speciation is poorly understood. Restricted recombination may promote linkage disequilibrium between the colour locus and incompatibility genes. Genomic rearrangement and the position of relevant loci within a chromosome are important factors that influence the frequency of recombination. Therefore, it is important to know the position of the colour locus, gene order and recombination landscape of the chromosome to understand the mechanism that generates incompatibilities between morphs. Recent studies showed remarkable pre- and postzygotic incompatibilities between sympatric colour morphs of the Gouldian finch (Erythrura gouldiae), in which head feather colour is genetically determined by a single sex-linked locus, Red. We constructed a genetic map for the Z chromosome of the Gouldian finch (male-specific map distance=131 cM), using 618 captive-bred birds and 34 microsatellite markers, to investigate the extent of inter- and intraspecific genomic rearrangements and variation in recombination rate within the Z chromosome. We refined the location of the Red locus to a ~7.2-cM interval in a region with a moderate recombination rate but outside the least-recombining, putative centromeric region. There was no evidence of chromosome-wide genomic rearrangements between the chromosomes carrying the red or black alleles with the current marker resolution. This work will contribute to identifying the causal gene, which will in turn enable alternative explanations for the association between incompatibility and colouration, such as fine-scale linkage disequilibrium, genomic rearrangements and pleiotropy, to be tested.

RESUMO

BACKGROUND AND PURPOSE: Early relapse outcomes in long-term stable patients switching from interferon ß/glatiramer acetate (IFNß/GA) to oral therapy are unknown. OBJECTIVE: The objective of this study was to compare early relapse and progression in multiple sclerosis (MS) patients switching to oral therapy following a period of stable disease on IFNß/GA, relative to a propensity-matched comparator of patients remaining on IFNß/GA. METHODS: The MSBase cohort study is a global, longitudinal registry for MS. Time to first 6-month relapse in previously stable MS patients switching from platform injectables ('switchers') to oral agents were compared with propensity-matched patients remaining on IFNß/GA ('stayers') using a Cox marginal model. RESULTS: Three-hundred and ninety-six switchers were successfully matched to 396 stayers on a 1:1 basis. There was no difference in the proportion of patients recording at least one relapse in the first 1-6 months by treatment arm (7.3% switchers, 6.6% stayers; P = 0.675). The mean annualized relapse rate (P = 0.493) and the rate of first 6-month relapse by treatment arm (hazard ratio 1.22, 95% confidence interval 0.70, 2.11) were also comparable. There was no difference in the rate of disability progression by treatment arm (hazard ratio 1.43, 95% confidence interval 0.63, 3.26). CONCLUSION: This is the first study to compare early relapse switch probability in the period immediately following switch to oral treatment in a population previously stable on injectable therapy. There was no evidence of disease reactivation within the first 6 months of switching to oral therapy.

RESUMO

OBJECTIVE: To evaluate the effectiveness and safety of an ultra-low-cost uterine balloon tamponade package (ESM-UBT™) for facility-based management of uncontrolled postpartum haemorrhage (PPH) in Kenya, Sierra Leone, Senegal, and Nepal. DESIGN: Prospective multi-centre case series. SETTING: Facilities in resource-scarce areas of Kenya, Sierra Leone, Nepal, and Senegal. POPULATION: Women with uncontrolled postpartum haemorrhage in 307 facilities across the four countries. METHODS: A standardised ESM-UBT package was implemented in 307 facilities over 29 months (1 September 2012 to 1 February 2015). Data were collected via a multi-pronged approach including data card completion, chart reviews, and provider interviews. Beginning in August 2014, women who had previously undergone UBT placement were sought and queried regarding potential complications associated with UBT use. MAIN OUTCOME MEASURES: All-cause survival, survival from PPH, and post-UBT use complications (surgery, hospitalisation, antibiotics for pelvic infection) associated with UBT use. RESULTS: 201 UBTs were placed for uncontrolled vaginal haemorrhage refractory to all other interventions. In all, 38% (71/188) of women were either unconscious or confused at the time of UBT insertion. All-cause survival was 95% (190/201). However, 98% (160/163) of women survived uncontrolled PPH if delivery occurred at an ESM-UBT online facility. One (1/151) potential UBT-associated complication (postpartum endometritis) was identified and two improvised UBTs were placed in women with a ruptured uterus. CONCLUSIONS: These pilot data suggest that the ESM-UBT package is a clinically promising and safe method to arrest uncontrolled postpartum haemorrhage and save women's lives. The UBT was successfully placed by all levels of facility-based providers. Future studies are needed to further evaluate the effectiveness of ESM-UBT in low-resource settings. TWEETABLE ABSTRACT: Evidence for ESM-UBT as a clinically promising and safe method to arrest uncontrolled PPH and save women's lives.

RESUMO

Treatment of metastatic soft tissue sarcoma (mSTS) commonly includes multiple lines of chemotherapy, until a decline in performance status precludes further treatment. The primary objective of this study was to describe the lifetime healthcare resource utilisation and cost among mSTS patients with favourable response to chemotherapy. SABINE was a multi-centre (n = 25), multi-country (n = 9) retrospective chart review study of mSTS patients with favourable response to chemotherapy following 4 cycles. Healthcare resource utilisation was collected from first line until death or end of follow-up. Costs were analysed by health states (defined by treatment line, chemotherapy use and disease progression) and estimated by multiplying the mean weekly cost per health state by the expected number of weeks spent in each health state. Expected per-patient lifetime medical cost was €65 616 (95% CI: €51 454-€85 003); comprised of IV chemotherapy (31.7%), inpatient care (24.8%), concomitant medication (11.0%), oral chemotherapy (8.9%), outpatient visits (8.8%), radiotherapy (6.3%), hospice (4.0%), imaging (3.7%) and laboratory (0.7%). Weekly costs were 280-330% higher during chemotherapy treatment periods than off-chemotherapy, especially after disease progression. Per-patient costs were highest in the USA and lowest in the Netherlands and UK. The economic burden of mSTS is considerable and the amount of resources devoted to its treatment varies across countries.

RESUMO

Health-related quality of life (HRQoL) assessment is recognized as an important outcome in the evaluation of different therapeutic regimens for persons with haemophilia. The Canadian Haemophilia Outcomes-Kids' Life Assessment Tool (CHO-KLAT) is a disease-specific measure of HRQoL for 4 to 18-year-old boys with haemophilia. The purpose of this study was to extend this disease-specific, child-centric, outcome measure for use in international clinical trials. We adapted the North American English CHO-KLAT version for use in five countries: France, Germany, the Netherlands, Spain and the United Kingdom (UK). The process included four stages: (i) translation; (ii) cognitive debriefing; (iii) validity assessment relative to the PedsQL (generic) and the Haemo-QoL (disease-specific) and (iv) assessment of inter and intra-rater reliability. Cognitive debriefing was performed in 57 boys (mean age 11.4 years), validation was performed in 144 boys (mean age 11.0 years) and reliability was assessed for a subgroup of 64 boys (mean age 12.0 years). Parents also participated. The mean scores reported by the boys were high: CHO-KLAT 77.0 (SD = 11.2); PedsQL 83.8 (SD = 11.9) and Haemo-QoL 79.6 (SD = 11.5). Correlations between the CHO-KLAT and PedsQL ranged from 0.63 in Germany to 0.39 in the Netherlands and Spain. Test-retest reliability (concordance) for child self-report was 0.67. Child-parent concordance was slightly lower at 0.57. The CHO-KLAT has been fully culturally adapted and validated for use in five different languages and cultures (in England, the Netherlands, France, Germany and Spain) where treatment is readily available either on demand or as prophylaxis.

RESUMO

Clinical networks have potential to increase elective surgical workload for benign conditions in non-cancer centres. The aims of this study were to determine outcomes for elective laparoscopic cholecystectomy in our unit and to evaluate early experience in managing benign surgical workload referred from the tertiary centre within our clinical network. An analysis of cholecystectomies performed at Mayo General Hospital was conducted (2003-2013). A review of elective procedures more recently referred from Galway University Hospital (GUH) waiting lists was also conducted. 1937 consecutive cholecystectomies were performed with an overall laparoscopic conversion rate of 1.7% (33/1875). The total major complication rate was 0.93% (18/1937). 151 selected procedures originating from GUH have been performed since December 2013 without adverse events. Laparoscopic cholecystectomy can be performed in significant volume in the general hospital environment. This and other appropriate benign surgical procedures may be performed outside of tertiary units according to network agreements.

RESUMO

A field-based assessment was conducted to assess maternal and newborn health-care services, perinatal and newborn outcomes and associated risk factors at Bint Al-Huda Maternal and Newborn Teaching Hospital, a large referral hospital in southern Iraq. The multi-method approach used interviews, discussions, observation and review of perinatal and newborn outcome data. There is limited assessment of maternal vital signs, labour pattern, fetal response, and complications during pregnancy and labour. Perinatal and neonatal mortality rates are 27.4/1000 births and 30.9/1000 live births respectively. Associated neonatal mortality factors were gestational age < 37 weeks, male sex, birth weight < 2.5 kg, maternal age > 35 years, rural maternal residence and vaginal delivery. Improving birth outcomes in southern Iraq requires evidence-based clinical guidelines, additional supplies and equipment, quality improvement initiatives and in-service training.

RESUMO

Extra-group paternity (EGP) occurs commonly among group-living mammals and plays an important role in mating systems and the dynamics of sexual selection; however, socio-ecological and genetic correlates of EGP have been underexplored. We use 23 years of demographic and genetic data from a high-density European badger (Meles meles) population, to investigate the relationship between the rate of EGP in litters and mate availability, mate incompatibility and mate quality (heterozygosity). Relatedness between within-group assigned mothers and candidate fathers had a negative quadratic effect on EGP, whereas the number of neighbouring-group candidate fathers had a linear positive effect. We detected no effect of mean or maximum heterozygosity of within-group candidate fathers on EGP. Consequently, EGP was associated primarily with mate availability, subject to within-group genetic effects, potentially to mitigate mate incompatibility and inbreeding. In badgers, cryptic female choice, facilitated by superfecundation, superfoetation and delayed implantation, prevents males from monopolizing within-group females. This resonates with a meta-analysis in group-living mammals, which proposed that higher rates of EGP occur when within-group males cannot monopolize within-group females. In contrast to the positive meta-analytic association, however, we found that EGP associated negatively with the number of within-group assigned mothers and the number of within-group candidate fathers; potentially a strategy to counter within-group males committing infanticide. The relationship between the rate of EGP and socio-ecological or genetic factors can therefore be intricate, and the potential for cryptic female choice must be accounted for in comparative studies.

RESUMO

Although the phylogeography of European mammals has been extensively investigated since the 1990s, many studies were limited in terms of sampling distribution, the number of molecular markers used and the analytical techniques employed, frequently leading to incomplete postglacial recolonisation scenarios. The broad-scale genetic structure of the European badger (Meles meles) is of interest as it may result from historic restriction to glacial refugia and/or recent anthropogenic impact. However, previous studies were based mostly on samples from western Europe, making it difficult to draw robust conclusions about the location of refugia, patterns of postglacial expansion and recent demography. In the present study, continent-wide sampling and analyses with multiple markers provided evidence for two glacial refugia (Iberia and southeast Europe) that contributed to the genetic variation observed in badgers in Europe today. Approximate Bayesian computation provided support for a colonisation of Scandinavia from both Iberian and southeastern refugia. In the whole of Europe, we observed a decline in genetic diversity with increasing latitude, suggesting that the reduced diversity in the peripheral populations resulted from a postglacial expansion processes. Although MSVAR v.1.3 also provided evidence for recent genetic bottlenecks in some of these peripheral populations, the simulations performed to estimate the method's power to correctly infer the past demography of our empirical populations suggested that the timing and severity of bottlenecks could not be established with certainty. We urge caution against trying to relate demographic declines inferred using MSVAR with particular historic or climatological events.

RESUMO

There is an increased trend towards the use of drug and enteric coated sugar spheres for controlled oral delivery of active pharmaceutical ingredients (API). This trend is driven by increased efficacy and ease of formulation of different dosage levels. However, difficulties exist in determining the thickness of drug and enteric coatings in a time efficient manner during manufacture, quality assurance and stability testing. The thickness of the coating determines the dosage of the API and the thickness of the enteric coating determines the release rate of the drug in the gastro-intestinal tract. Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS) offers a rapid new approach to characterising the enteric coating thickness and the raw materials used in their manufacture. BARDS applications are based on reproducible changes in the compressibility of a solvent during dissolution which is monitored acoustically due to associated changes in the speed of sound in solution. It is demonstrated how core delivery sugar spheres have unique acoustic spectra attributable to the mean size distribution of the spheres. A steady state acoustic lag time is associated with the disintegration of the enteric coating, in basic solution. This lag time can be manipulated by varying the concentration of the base which affects the rate at which the coating dissolves. It is anticipated that the thickness/loading of the spheres can be estimated from the lag time.

RESUMO

The present study endeavored to calculate a conservative estimate of both incidence- and prevalence-based costs of nonepileptic attack disorder (NEAD) in Ireland by applying previously identified prevalence figures to Irish population figures. Variables related to the economic cost of NEAD were identified based on a retrospective chart review of patients diagnosed with NEAD at Beaumont Hospital, Dublin. The annual cost per patient of undiagnosed NEAD was calculated as €20,995.30. The combined cost of diagnosis and psychological treatment of NEAD was estimated at €8728. Although it is difficult to determine precise economic costings, early diagnosis and intervention would result in a significant economic saving to the exchequer, a reduction in hospital waiting-list times, and a better prognosis for patients.

RESUMO

BACKGROUND: Managing multiple sclerosis (MS) in people of reproductive age can be challenging as treatment decisions often need to balance efficacy, safety to reproductive health and an understanding of reproductive intentions. There has been limited examination of how family planning (FP) is approached in people with MS (pwMS) in Australia. This study aimed to explore the experiences and perspectives of Australian MS clinical specialists on managing FP in the context of MS. METHODS: We conducted one-on-one semi-structured interviews with nine neurologists and ten MS nurses across Australia who regularly provide care to pwMS of reproductive age. Interview topics examined current approaches to managing FP, availability of FP resources, and opportunities for improvement. Interview recordings were transcribed verbatim and analysed thematically. RESULTS: Two main themes emerged. First, 'inconsistent approaches in providing family planning', where neurologists and MS nurses recognised FP provision as essential but revealed differences in the content, timing and extent of FP discussions; conflicts between reproductive considerations and DMT prescriptions according to teratogenic risk; and variable implementation of interdisciplinary approaches. Second, 'barriers in providing family planning' emerged which included a lack of local information resources on FP, lack of contemporary data on safety of DMTs, and a range of patient and professional factors, including time constraints. CONCLUSION: MS clinical specialists saw FP as an essential part of the care of their patients and expressed a need for information and service provision consistency in order to improve FP and reproductive care to pwMS.
