RESUMO
BACKGROUND: Group psychotherapy for older adults with generalised anxiety disorder is an under-researched area. AIM: This report describes a mixed method evaluation of the acceptability and feasibility of an Overcoming Worry Group. METHOD: The Overcoming Worry Group was a novel adaptation of a cognitive behavioural therapy protocol targeting intolerance-of-uncertainty for generalised anxiety disorder, tailored for delivery to older adults in a group setting (n = 13). RESULTS: The adapted protocol was found to be acceptable and feasible, and treatment outcomes observed were encouraging. CONCLUSIONS: This proof-of-concept study provides evidence for an Overcoming Worry Group as an acceptable and feasible group treatment for older adults with generalised anxiety disorder.

The evidence base for treatment of bipolar affective disorder (BD) demands the evaluation of new psychotherapies in order to broaden patient choice. This study reports on the feasibility, safety, helpfulness and effectiveness of cognitive analytic therapy (CAT). In a pilot randomized controlled trial, BD patients in remission were randomized to either receiving 24 sessions of CAT (n = 9) or treatment as usual (n = 9) and were assessed in terms of symptoms, functioning and service usage over time. In the CAT arm no adverse events occurred, 8/9 completed treatment, 5/8 attended all 24 sessions and 2/8 were categorized as recovered. The most common helpful event during CAT was recognition of patterns in mood variability, with helpfulness themes changing according to phase of therapy. No major differences were found when comparing the arms over time in terms of service usage or psychometric outcomes. The study suggests that conducting further research into the effectiveness of CAT in treating BD is warranted and guidance regarding future trials is provided. Copyright © 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Treating BD with CAT appears feasible and safe. Retaining fidelity to the reformulation, recognition and revision structure of CAT appears useful. Participants stated that across the phases of CAT, focussing on patterns of mood variability was consistently helpful.

OBJECTIVE: Generalized anxiety disorder (GAD) is a common disorder in older adults producing functional impairment, and psychotherapy is the preferred treatment option. Meta-analytic methods sought to determine the efficacy of outpatient cognitive behavioral therapy (CBT) with respect to the hallmark feature of GAD-uncontrolled and excessive worry. In order to optimize clinical applicability, variables associated with GAD treatment outcomes were also examined. METHODS: Systematic search of relevant databases and iterative searches of references from articles retrieved. All studies were required to have been a randomized control trial (RCT), to have used the Penn State Worry Questionnaire (PSWQ) or its abbreviated version (PSWQ-A) as an outcome measure, and to have conducted CBT with outpatient older adults. Fourteen RCTs (N = 985) were suitable and random-effects meta-analyses and univariate meta-regressions were conducted. RESULTS: At the end of treatment, and at 6-month follow-up, significant treatment effects favoring CBT were found in comparison to a waitlist or treatment-as-usual. When CBT was compared with active controls, a small nonsignificant treatment advantage was found for CBT at the end of treatment, with equivalence of outcomes at follow-up. Treatment effect size of CBT for GAD was significantly associated with attrition rates and depression outcomes. CONCLUSIONS: CBT is more helpful than having no treatment for GAD in later life. Nevertheless, whether CBT shows long-term durability, or is superior to other commonly available treatments (such as supportive psychotherapy), remains to be tested. The relationship between treatment effects for GAD and depression following CBT warrants further research.

For a single species, human kinship organization is both remarkably diverse and strikingly organized. Kinship terminology is the structured vocabulary used to classify, refer to, and address relatives and family. Diversity in kinship terminology has been analyzed by anthropologists for over 150 years, although recurrent patterning across cultures remains incompletely explained. Despite the wealth of kinship data in the anthropological record, comparative studies of kinship terminology are hindered by data accessibility. Here we present Kinbank, a new database of 210,903 kinterms from a global sample of 1,229 spoken languages. Using open-access and transparent data provenance, Kinbank offers an extensible resource for kinship terminology, enabling researchers to explore the rich diversity of human family organization and to test longstanding hypotheses about the origins and drivers of recurrent patterns. We illustrate our contribution with two examples. We demonstrate strong gender bias in the phonological structure of parent terms across 1,022 languages, and we show that there is no evidence for a coevolutionary relationship between cross-cousin marriage and bifurcate-merging terminology in Bantu languages. Analysing kinship data is notoriously challenging; Kinbank aims to eliminate data accessibility issues from that challenge and provide a platform to build an interdisciplinary understanding of kinship.

Zika virus (ZIKV) cases continue to be reported, and no vaccine or specific antiviral agent has been approved for the prevention or treatment of infection. Though ZIKV is primarily transmitted by mosquitos, cases of sexual transmission and prolonged viral RNA presence in semen have been reported. In this observational study, we report the mucosal responses to sub-cutaneous and mucosal ZIKV exposure in cynomolgus macaques during acute and late chronic infection. Subcutaneous challenge induced a decrease in the growth factor VEGF in colorectal and cervicovaginal tissues 100 days post-challenge, in contrast to the observed increase in these tissues following vaginal infection. This different pattern was not observed in the uterus, where VEGF was upregulated independently of the challenge route. Vaginal challenge induced a pro-inflammatory profile in all mucosal tissues during late chronic infection. Similar responses were already observed during acute infection in a vaginal tissue explant model of ex vivo challenge. Non-productive and productive infection 100 days post-in vivo vaginal challenge induced distinct proteomic profiles which were characterized by further VEGF increase and IL-10 decrease in non-infected animals. Ex vivo challenge of mucosal explants revealed tissue-specific modulation of cytokine levels during the acute phase of infection. Mucosal cytokine profiles could represent biosignatures of persistent ZIKV infection.
RESUMO
SARS-CoV-2 exhibits a diverse host species range with variable outcomes, enabling differential host susceptibility studies to assess suitability for pre-clinical countermeasure and pathogenesis studies. Baseline virological, molecular and pathological outcomes were determined among multiple species-one Old World non-human primate (NHP) species (cynomolgus macaques), two New World NHP species (red-bellied tamarins; common marmosets) and Syrian hamsters-following single-dose, atraumatic intranasal administration of SARS-CoV-2/Victoria-01. After serial sacrifice 2, 10 and 28-days post-infection (dpi), hamsters and cynomolgus macaques displayed differential virus biodistribution across respiratory, gastrointestinal and cardiovascular systems. Uniquely, New World tamarins, unlike marmosets, exhibited high levels of acute upper airway infection, infectious virus recovery associated with mild lung pathology representing a host previously unrecognized as susceptible to SARS-CoV-2. Across all species, lung pathology was identified post-clearance of virus shedding (antigen/RNA), with an association of virus particles within replication organelles in lung sections analysed by electron microscopy. Disrupted cell ultrastructure and lung architecture, including abnormal morphology of mitochondria 10-28 dpi, represented on-going pathophysiological consequences of SARS-CoV-2 in predominantly asymptomatic hosts. Infection kinetics and host pathology comparators using standardized methodologies enables model selection to bridge differential outcomes within upper and lower respiratory tracts and elucidate longer-term consequences of asymptomatic SARS-CoV-2 infection.

Zika virus (ZIKV) causes neurological complications in susceptible individuals, highlighted in the recent South American epidemic. Natural ZIKV infection elicits host responses capable of preventing subsequent re-infection, raising expectations for effective vaccination. Defining protective immune correlates will inform viral intervention strategies, particularly vaccine development. Non-human primate (NHP) species are susceptible to ZIKV and represent models for vaccine development. The protective efficacy of a human anti-ZIKV convalescent plasma pool (16/320-14) developed as a candidate reference material for a WHO International Standard was evaluated in macaques. Convalescent plasma administered to four cynomolgus macaques (Macaca fascicularis) intra-peritoneally 24 hrs prior to sub-cutaneous challenge with 103 pfu ZIKVPRVABC59 protected against detectable infection, with absence of detectable ZIKV RNA in blood and lymphoid tissues. Passively immunised anti-ZIKV immunoglobulin administered prior to time of challenge remained present only at very low levels 42 days post-challenge. Absence of de novo antibody responses in passively immunised macaques indicate sterilising immunity compared with naïve challenge controls that exhibited active ZIKV-specific IgM and IgG responses post-challenge. Demonstration that the presence of convalescent anti-ZIKV at levels of 400 IU/mL neutralising antibody protects against virus challenge provides a scientific framework for development of anti-ZIKV vaccines and facilitates regulatory approval.
RESUMO
South American Zika virus (ZIKV) recently emerged as a novel human pathogen, linked with neurological disorders. However, comparative ZIKV infectivity studies in New World primates are lacking. Two members of the Callitrichidae family, common marmosets (Callithrix jacchus) and red-bellied tamarins (Saguinus labiatus), were highly susceptible to sub-cutaneous challenge with the Puerto Rico-origin ZIKVPRVABC59 strain. Both exhibited rapid, high, acute viraemia with early neuroinvasion (3 days) in peripheral and central nervous tissue. ZIKV RNA levels in blood and tissues were significantly higher in New World hosts compared to Old World species (Macaca mulatta, Macaca fascicularis). Tamarins and rhesus macaques exhibited loss of zonal occludens-1 (ZO-1) staining, indicative of a compromised blood-brain barrier 3 days post-ZIKV exposure. Early, widespread dissemination across multiple anatomical sites distant to the inoculation site preceded extensive ZIKV persistence after 100 days in New and Old World lineages, especially lymphoid, neurological and reproductive sites. Prolonged persistence in brain tissue has implications for otherwise resolved human ZIKV infection. High susceptibility of distinct New World species underscores possible establishment of ZIKV sylvatic cycles in primates indigenous to ZIKV endemic regions. Tamarins and marmosets represent viable New World models for ZIKV pathogenesis and therapeutic intervention studies, including vaccines, with contemporary strains.

AIM: This paper is a report of a study to develop a social outreach model of care, including the role of a link worker in developing collaborative care pathways, for marginalized groups with tuberculosis. BACKGROUND: Social risk factors such as homelessness and substance misuse are associated with poor treatment outcomes. Models of interprofessional practice to address the health and social care of patients are needed to improve outcomes. METHODS: A process evaluation involving a prospective cohort study of 100 patients and interviews with eight agencies involved in their care was conducted in London between January 2003 and April 2005. Outcome measures included a profile of patient need to guide service development; referrals to care providers; goal attainment; social improvement and treatment outcomes; and agencies' views on the benefits of link working. FINDINGS: The median age of the sample was 32.4 years and 62% were males. Reasons for referral to the link worker included housing need (56%); welfare benefits (42%); immigration (29%) and clinical management issues (28%). One-third of the patients were referred to other agencies. Goals, as agreed in the care plan, were attained totally or partially for 88% (59/67) of patients and 78% of patients successfully completed treatment. Barriers to attaining goals included service criteria which excluded some groups of patients and, in some cases, a patient's inability to follow a course of action. CONCLUSION: Link workers can mitigate some of the social risk factors that complicate the treatment of tuberculosis by enabling integrated health and social care.

BACKGROUND: Narrative reformulation (NR) is a component of cognitive analytic therapy (CAT) that is assumed to increase client engagement and improve clinical outcomes. This study set out to test these claims. METHODS: A single-blind randomized and controlled dismantling trial investigated treatment outcomes for moderate to severely depressed patients receiving CAT in Primary Care. Ninety-five participants were randomized to either full-CAT (nâ¯=â¯52) or CAT minus narrative reformulation (CAT-NR, nâ¯=â¯43). Treatment duration in both arms was 8-sessions and was matched apart from the omission of the NR in the CAT-NR arm. The primary outcome measure was the Patient Health Questionnaire (PHQ-9), with secondary outcome measures of anxiety, functioning, helpfulness and the therapeutic alliance. Outcomes were assessed at screening, every treatment session and at 8-weeks follow-up. RESULTS: Growth curve modelling found that NR did not enhance the efficacy of CAT for depression. There were no significant differences between groups in terms of attendance, adverse events, anxiety, functioning, helpfulness or therapeutic alliance. There were large within-group effect sizes (d+â¯>â¯1.5), as CAT with or without NR produced significant reductions in depression (pâ¯<â¯.01). LIMITATIONS: The primary outcome were assessed via self-report and the follow-up period was brief. CONCLUSIONS: These results suggest that NR may be redundant when treating depression with CAT. Whilst a brief 8-session version of the CAT model appears suitable for treating depression in Primary Care, further research regarding the need for NR is indicated.

Background and aims This review appraises the progression and status of the evidence base for the treatment of compulsive buying disorder (CBD), in order to highlight what currently works and to prompt useful future research. Methods Online databases ISI Web of Knowledge, PsycINFO, and PubMed via Ovid were searched at two time points. Two quality checklists and an established model of therapy evaluation (hourglass model) evaluated the quality and progression of both psychotherapy and pharmacotherapy treatments for CBD. Uncontrolled effect sizes were calculated and meta-regression analyses were performed regarding treatment duration. Results A total of 29 articles met the inclusion criteria, which were divided into psychotherapy (n = 17) and pharmacotherapy treatments (n = 12). Of the 29 studies, only 5 studies have been tested under conditions of high methodological quality. Both forms of treatment had been evaluated in a haphazard manner across the stages of the hourglass model. Although large effects were demonstrated for group psychotherapy and pharmacotherapy, such evidence of effectiveness was undermined by poor study quality and risk of publication bias. Long-term CBD treatment was associated with improved outcome with pharmacotherapy, but not when delivering psychotherapy. Discussion Group psychotherapy currently appears the most promising treatment option for CBD. Poor methodological control and sporadic evaluation of specific treatments have slowed the generation of a convincing evidence base for CBD treatment. Defining the active ingredients of effective CBD treatment is a key research goal.
