Assessing victim risk in cases of violent crime
Purpose: There is a body of evidence that suggests a range of psychosocial characteristics demarcate certain adults to be at an elevated risk for victimisation. To this end, the aim of the current study was to examine consistency between one police force, and a corresponding victim support service based in England, in their assessment of level of risk faced by victims of violent crime.
Methodology: This study explored matched data on 869 adult victims of violent crime gathered from these two key services in Preston, namely Lancashire Constabulary and Victim Support, from which a sub-group of comparable ‘domestic violence’ cases (n=211) were selected for further examination.
Findings: Data analyses revealed methodological inconsistencies in the assessment of victimisation resulting in discrepancies for recorded levels of risk in domestic violence cases across these two agencies.
Practical implications: These findings provide a compelling argument for developing a more uniformed approach to victim assessment and indicate a significant training need.
Value: This paper highlights areas of good practice and forwards several recommendations for improved practice that emphasises the integration of empirical research conducted by psychologists to boost the validity and reliability of risk assessment approaches and tools used
Repeat Victimisation, Retraumatisation and Victim Vulnerability
Abstract: This study explores the contribution that traumatic experiences and psychological post-traumatic stress symptoms make to predicting subsequent revictimisation in a sample of violent crime victims. In addition, the timing of first trauma exposure was also explored. Fifty-four adult victims (27 male and 27 female) of police recorded violent crime were interviewed and their traumatic exposure history, trauma symptomology, age at first trauma exposure as well as psychological and psychosocial functioning were assessed. These victims were followed longitudinally and subsequent revictimisation between six and twelve months post index victimisation measured. A greater number of types of trauma exposure was related lower emotional stability, higher trauma symptomology and revictimisation. Those victims with childhood traumatic exposure reported more trauma symptomology exposure than those without prior exposure. The implications for law enforcement and victim services are discussed

CD24 signalling through macrophage Siglec-10 is a target for cancer immunotherapy.
Ovarian cancer and triple-negative breast cancer are among the most lethal diseases affecting women, with few targeted therapies and high rates of metastasis. Cancer cells are capable of evading clearance by macrophages through the overexpression of anti-phagocytic surface proteins called 'don't eat me' signals-including CD471, programmed cell death ligand 1 (PD-L1)2 and the beta-2 microglobulin subunit of the major histocompatibility class I complex (B2M)3. Monoclonal antibodies that antagonize the interaction of 'don't eat me' signals with their macrophage-expressed receptors have demonstrated therapeutic potential in several cancers4,5. However, variability in the magnitude and durability of the response to these agents has suggested the presence of additional, as yet unknown 'don't eat me' signals. Here we show that CD24 can be the dominant innate immune checkpoint in ovarian cancer and breast cancer, and is a promising target for cancer immunotherapy. We demonstrate a role for tumour-expressed CD24 in promoting immune evasion through its interaction with the inhibitory receptor sialic-acid-binding Ig-like lectin 10 (Siglec-10), which is expressed by tumour-associated macrophages. We find that many tumours overexpress CD24 and that tumour-associated macrophages express high levels of Siglec-10. Genetic ablation of either CD24 or Siglec-10, as well as blockade of the CD24-Siglec-10 interaction using monoclonal antibodies, robustly augment the phagocytosis of all CD24-expressing human tumours that we tested. Genetic ablation and therapeutic blockade of CD24 resulted in a macrophage-dependent reduction of tumour growth in vivo and an increase in survival time. These data reveal CD24 as a highly expressed, anti-phagocytic signal in several cancers and demonstrate the therapeutic potential for CD24 blockade in cancer immunotherapy
Predictors of engagement with support services in a sample of UK victims of violent crime.
Research suggests that engagement with support services after criminal victimisation is low. With this in mind, this study investigated predictors of engagement with Victim Support, in a sample of victims of violent crime. All violent crimes recorded by Lancashire Constabulary for two postcode areas (PR1 and PR2), who were referred to Victim Support (Preston) between April 2013 and September 2013 (n=869) were assessed, with a follow-up undertaken in 2014. Two percent of victims booked or attended a face-to-face meeting with Victim Support, and just over one fifth engaged over the telephone on at least one occasion across a range of support options at the initial data collection point. Engagement with Victim Support was not significantly related to future victimisation. When revictimisation since the first data collection period was inspected against demographic and crime-related variables, previous victimisation, regardless of the type of crime experienced, was the strongest predictor of being victimised again. This was despite the fact that such victims were more likely to be identified as high risk, and actively engaged with Victim Support at the initial time of victimisation. Suggestions for further research are made in light of the changes generally to victim services in the UK

Enhancing the student learning experience through memes
Meme-making is an effective method for engaging students and enhancing the learning environment. Memes are a social media cultural phenomenon that the majority of those in Higher Education are exposed to on an almost daily occurrence. This research examined the use of meme-making within the forensic sciences to allow students to reflect on their knowledge. Students studying modules in forensic science across six universities in the UK and USA participated in the study. At the end of a teaching session, students produced a meme (using Meme Generator) to reflect on what they had learned; memes were then shared with the class anonymously via Padlet. This allowed all class members to see and engage with the memes created. At the end of the activity students were anonymously surveyed on their experience using Microsoft Forms and analysis of the results were undertaken using SPSS software.Meme-making was found to be an inclusive learning activity with no limitations, including age (part-time, distance learning and visually impaired students were not part of the study parameters). Results showed that not only did students find the practice fun, but it also helped with the retention of the class content suggesting that the meme-making process is an effective way to enhance the learning environment while engaging students.Student feedback suggests that to maximise participation the educator should stress reflection and learning as the key purpose of generating a meme, rather than being witty or entertaining. The forensic science educator should be mindful of selecting appropriate subject matter for this often-humorous activity
The effectiveness of manual stretching in the treatment of plantar heel pain: a systematic review
Background: Plantar heel pain is a commonly occurring foot complaint. Stretching is frequently utilised as a treatment, yet a systematic review focusing only on its effectiveness has not been published. This review aimed to assess the effectiveness of stretching on pain and function in people with plantar heel pain. Methods: Medline, EMBASE, CINAHL, AMED, and The Cochrane Library were searched from inception to July 2010. Studies fulfilling the inclusion criteria were independently assessed, and their quality evaluated using the modified PEDro scale. Results: Six studies including 365 symptomatic participants were included. Two compared stretching with a control, one study compared stretching to an alternative intervention, one study compared stretching to both alternative and control interventions, and two compared different stretching techniques and durations. Quality rating on the modified Pedro scale varied from two to eight out of a maximum of ten points. The methodologies and interventions varied significantly between studies, making meta-analysis inappropriate. Most participants improved over the course of the studies, but when stretching was compared to alternative or control interventions, the changes only reached statistical significance in one study that used a combination of calf muscle stretches and plantar fascia stretches in their stretching programme. Another study comparing different stretching techniques, showed a statistically significant reduction in some aspects of pain in favour of plantar fascia stretching over calf stretches in the short term. Conclusions: There were too few studies to assess whether stretching is effective compared to control or other interventions, for either pain or function. However, there is some evidence that plantar fascia stretching may be more effective than Achilles tendon stretching alone in the short-term. Appropriately powered randomised controlled trials, utilizing validated outcome measures, blinded assessors and long-term follow up are needed to assess the efficacy of stretching
Typical 22q11.2 deletion syndrome appears to confer a reduced risk of schwannoma
Purpose: The LZTR1 gene has been associated with schwannomatosis tumor predisposition and is located in a region that is deleted in the great majority (89%) of patients with 22q11.2 deletion syndrome (22q11.2DS). Since it is known that approximately 1 in 500 people in the general population will develop a sporadic schwannoma and there are no reports of the occurrence of schwannoma in 22q11.2DS, we investigated whether whole-gene deletion of LZTR1 occurs in schwannomatosis and assessed the risk of schwannoma in 22q11.2DS. Methods: We assessed the genetic testing results for LZTR1-associated schwannomatosis and the clinical phenotypes of patients with 22q11.2DS. Results: There were no reports of schwannoma in over 1,500 patients with 22q11.2DS. In addition, no patients meeting clinical diagnostic criteria for schwannomatosis had a whole-gene deletion in LZTR1. Only 1 patient in 110 with an apparently sporadic vestibular schwannoma had a constitutional whole-gene deletion of LZTR1. Conclusion: People with a large 22q11.2 deletion may have a reduced risk of developing a schwannoma compared to the general population
