There are few UK data on the prevalence and clustering of risky behaviours in ethnically diverse adolescents.

To investigate the prevalence of reported alcohol use, smoking and vaping, and explore whether these behaviours are associated with increased numbers of sexual partners.

Questionnaire survey of 'Test n Treat' chlamydia screening trial participants.

Sexually active students attending six London technical colleges completed confidential questionnaires and provided genitourinary samples.

The median age of the 509 participants was 17years (IQR 16-18), 47% were male, 50% were of black ethnicity, 55% reported ≥2 sexual partners in the past year (67% of males and 45% of females) and 6.2% had chlamydia infection and 0.6% gonorrhoea. Almost half (48%) reported getting drunk in the past month, 33% smoked cigarettes and 7% had ever vaped. A larger percentage of students with ≥2 sexual partners than 0-1 partners reported getting drunk in the past month (53.7%, 144/268% versus 42.2% 94/223, adjusted prevalence ratio 1.33, 95% confidence interval 1.11-1.61) and smoking cigarettes (36.6%, 100/273% versus 30.2%, 67/222, 1.34 (1.05-1.70)). By contrast, multiple sexual partners were not associated with vaping or chlamydia infection, but numbers were small.

We found high prevalences of risky behaviour and an association between multiple sexual partners and smoking and/or getting drunk. Findings support the introduction of compulsory sex and relationship education in UK secondary schools, including information about the adverse effects of alcohol and smoking.

This prospective pilot study was conducted to evaluate the outcome of a commercially available corneal stroma substitute, Acellular Porcine Corneal Stroma (APCS), in dogs undergoing penetrating keratoplasty (PK) to restore corneal integrity after having deep ulcers.

Five dogs (1 eye in each dog) underwent a PK using APCS (BioCorneaVet™) as a graft. The surgical procedure and peri- and postoperative treatment were standardized. All cases required a minimum 6months follow-up. Ease of keratoprosthetic tissue handling, graft survival, anterior chamber stability, corneal opacity, neovascularization and re-epithelialization were noted. Presence of secondary uveitis was investigated.

BioCorneaVet™ was easy to handle and, at all-time points, provided adequate tectonic support. Graft survival was achieved in all 5 cases. A minimum follow-up period of 10months was available for the five eyes (22months maximum). Degree and area of corneal graft opacity progressively improved resulting in minimal to moderate loss of transparency in all cases but one, where it was severe. Neovascularization degree was most severe 0.5-1month after surgery and fully resolved 4-6months post-surgery. Re-epithelialization was complete in the majority of grafts in 1month. Secondary uveitis was not detected at any time in 4 of 5 dogs.

BioCorneaVet™ seems to be an effective graft for PK in the dog. In this case series, APCS was convenient to handle during surgery and provided excellent tectonic support. The material showed good tissue biocompatibility and resulted in the majority of cases in minimal to moderate graft opacity, that ameliorates with time.

Most existing research on the family context of psychosis focuses on the 'burden' of caring for people experiencing psychosis. This research is the first to ask young people experiencing early psychosis to 'map' and describe their experiences and understandings of their family relationships, and how they have related to their psychosis and recovery.

The research took an inductive, multimodal hermeneutic-phenomenological approach (Boden, Larkin & Iyer, 2019, Qual. Res. Psychology, 16, 218-236; Boden & Larkin, 2020, A handbook of visual methods in psychology, 358-375).

Ten young adults (18-23), under the care of early intervention in psychosis services in the UK, participated in an innovative relational mapping interview (Boden, Larkin & Iyer, 2018), which invited participants to draw a subjective 'map' of their important relationships. This visual methodology enables subtle, complex, ambivalent, and ambiguous aspects of the participants' experiences to be explored.

Findings explore the parte sense of their family dynamics and how this impacts on their recovery. Attachment-based and relationally oriented interventions that increase trust and openness, and reduce feelings of burdensomeness are likely to support family functioning as well as individual recovery.Recent discoveries show that fungi can take up environmental RNA, which can then silence fungal genes through environmental RNA interference. This discovery prompted the development of Spray-Induced Gene Silencing (SIGS) for plant disease management. In this study, we aimed to determine the efficacy of SIGS across a variety of eukaryotic microbes. We first examined the efficiency of RNA uptake in multiple pathogenic and non-pathogenic fungi, and an oomycete pathogen. We observed efficient double-stranded RNA (dsRNA) uptake in the fungal plant pathogens Botrytis cinerea, Sclerotinia sclerotiorum, Rhizoctonia solani, Aspergillus niger and Verticillium dahliae, but no uptake in Colletotrichum gloeosporioides, and weak uptake in a beneficial fungus, Trichoderma virens. For the oomycete plant pathogen, Phytophthora infestans, RNA uptake was limited and varied across different cell types and developmental stages. Topical application of dsRNA targeting virulence-related genes in pathogens with high RNA uptake efficiency significantly inhibited plant disease symptoms, whereas the application of dsRNA in pathogens with low RNA uptake efficiency did not suppress infection. Our results have revealed that dsRNA uptake efficiencies vary across eukaryotic microbe species and cell types. The success of SIGS for plant disease management can largely be determined by the pathogen's RNA uptake efficiency.
