    This report summarises findings from a project funded by the Home Office Perpetrator fund, which explored the characteristics, needs, and outcomes of those engaging with Domestic Abuse Perpetrator Programmes (DAPPs) within England and Wales between 2018 and 2021. Research suggests that the aetiology of domestic violence and abuse (DVA), including intimate partner violence (IPV), is complex, and that traditional feminist explanations of these behaviours may be inadequate in isolation. Moreover, whilst several DAPPs are available and accessible within England and Wales, current evaluative research suggests that their efficacy may be limited (potentially as a function of their construction around feminist, rather than vulnerability-based approaches). The current project sought to utilise data from 1,060 DAPP service users to better understand their characteristics, needs, and outcomes, to help inform discourse around current efficacy of DAPPs within England and Wales. Analysis was conducted on three themes of variables: demographic characteristics/abuse context, programme characteristics, and outcomes. Descriptive statistics revealed a client profile high in need, for example in relation to ACEs, mental health issues, and substance use. Several questions were also raised in relation to the type of data collected (for example, what was meant by ‘voluntary’ versus ‘mandatory’ attendance). Interestingly, both client and caseworker ratings indicated that, on average, programmes were also not hugely effective across several measures, and that few variables predicted strongly predicted outcomes. However, other meaningful relationships did emerge, for example between demographic/context variables (i.e., risk level and type of abuse). Taken together, results suggest that DAPPs in England and Wales aren’t currently reaching maximum efficacy in helping to facilitate behavioural change in DVA perpetrators, and that the data currently gathered by such programmes may require revision. This is discussed in relation to the structure and theoretical approach of the programmes included in this dataset

    Background Previous evidence indicates that adjuvant, short-course androgen deprivation therapy (ADT) improves metastasis-free survival when given with primary radiotherapy for intermediate-risk and high-risk localised prostate cancer. However, the value of ADT with postoperative radiotherapy after radical prostatectomy is unclear. Methods RADICALS-HD was an international randomised controlled trial to test the efficacy of ADT used in combination with postoperative radiotherapy for prostate cancer. Key eligibility criteria were indication for radiotherapy after radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to radiotherapy alone (no ADT) or radiotherapy with 6 months of ADT (short-course ADT), using monthly subcutaneous gonadotropin-releasing hormone analogue injections, daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as distant metastasis arising from prostate cancer or death from any cause. Standard survival analysis methods were used, accounting for randomisation stratification factors. The trial had 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 80% to 86% (hazard ratio [HR] 0·67). Analyses followed the intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov, NCT00541047. Findings Between Nov 22, 2007, and June 29, 2015, 1480 patients (median age 66 years [IQR 61–69]) were randomly assigned to receive no ADT (n=737) or short-course ADT (n=743) in addition to postoperative radiotherapy at 121 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 9·0 years (IQR 7·1–10·1), metastasis-free survival events were reported for 268 participants (142 in the no ADT group and 126 in the short-course ADT group; HR 0·886 [95% CI 0·688–1·140], p=0·35). 10-year metastasis-free survival was 79·2% (95% CI 75·4–82·5) in the no ADT group and 80·4% (76·6–83·6) in the short-course ADT group. Toxicity of grade 3 or higher was reported for 121 (17%) of 737 participants in the no ADT group and 100 (14%) of 743 in the short-course ADT group (p=0·15), with no treatment-related deaths. Interpretation Metastatic disease is uncommon following postoperative bed radiotherapy after radical prostatectomy. Adding 6 months of ADT to this radiotherapy did not improve metastasis-free survival compared with no ADT. These findings do not support the use of short-course ADT with postoperative radiotherapy in this patient population

    Duration of androgen deprivation therapy with postoperative radiotherapy for prostate cancer: a comparison of long-course versus short-course androgen deprivation therapy in the RADICALS-HD randomised trial

    Background Previous evidence supports androgen deprivation therapy (ADT) with primary radiotherapy as initial treatment for intermediate-risk and high-risk localised prostate cancer. However, the use and optimal duration of ADT with postoperative radiotherapy after radical prostatectomy remains uncertain. Methods RADICALS-HD was a randomised controlled trial of ADT duration within the RADICALS protocol. Here, we report on the comparison of short-course versus long-course ADT. Key eligibility criteria were indication for radiotherapy after previous radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to add 6 months of ADT (short-course ADT) or 24 months of ADT (long-course ADT) to radiotherapy, using subcutaneous gonadotrophin-releasing hormone analogue (monthly in the short-course ADT group and 3-monthly in the long-course ADT group), daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as metastasis arising from prostate cancer or death from any cause. The comparison had more than 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 75% to 81% (hazard ratio [HR] 0·72). Standard time-to-event analyses were used. Analyses followed intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov , NCT00541047 . Findings Between Jan 30, 2008, and July 7, 2015, 1523 patients (median age 65 years, IQR 60–69) were randomly assigned to receive short-course ADT (n=761) or long-course ADT (n=762) in addition to postoperative radiotherapy at 138 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 8·9 years (7·0–10·0), 313 metastasis-free survival events were reported overall (174 in the short-course ADT group and 139 in the long-course ADT group; HR 0·773 [95% CI 0·612–0·975]; p=0·029). 10-year metastasis-free survival was 71·9% (95% CI 67·6–75·7) in the short-course ADT group and 78·1% (74·2–81·5) in the long-course ADT group. Toxicity of grade 3 or higher was reported for 105 (14%) of 753 participants in the short-course ADT group and 142 (19%) of 757 participants in the long-course ADT group (p=0·025), with no treatment-related deaths. Interpretation Compared with adding 6 months of ADT, adding 24 months of ADT improved metastasis-free survival in people receiving postoperative radiotherapy. For individuals who can accept the additional duration of adverse effects, long-course ADT should be offered with postoperative radiotherapy.

    São apresentadas as características anatômicas da artéria coróidea anterior (AChA), encontradas nas dissecações de 100 hemisférios cerebrais de cadáveres humanos, realizadas sob microscópio cirúrgico. Foi encontrada uma AChA por hemisfério cerebral, 98% originando-se da artéria carótida interna (ACI) 2,4mm distai à origem da artéria comunicante posterior (ACoP) e 4,7mm proximal à bifurcação da ACI. Em 29% dos hemisférios havia ramos perfurantes emergindo da porção comunicante da ACI. A média do calibre da AChA foi 0,9mm na sua porção cisternal e 0,7mm na porção plexal. Os ramos mais freqüentes da porção cisterna da AChA foram para o trato óptico, pedúnculo cerebral, uncus e corpo geniculado lateral. Foram observadas anastomoses de ramos da AChA com ramos da artéria cerebral posterior, ACoP, artéria cerebral média e ACI. Os resultados são comparados àqueles da literatura
