Age-related macular degeneration (AMD) is one of the leading causes of irreversible blindness in the developed world. Antivascular endothelial growth factor therapy has transformed the management and outcome of neovascular AMD (nAMD), although the need for repeated intravitreal injections-even lifelong-and the related complications, high drug costs, frequent clinic visits and repeated imaging have resulted in an enormous burden both to healthcare systems and patients. The application of gene therapy approaches for sustained delivery of a range of antiangiogenic proteins has the promise of helping to address these aforementioned challenges. A number of early phase clinical trials of gene therapy in nAMD have provided encouraging results, with many more ongoing or anticipated. There remain significant areas of controversy, including regarding the optimal treatment targets, routes of administration and potential safety concerns. In this review we aim to provide an update of the current status of gene therapy for nAMD and briefly discuss future prospects. © Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY.

Our aim is to characterise body mass index (BMI)-associated pathological changes in the osteochondral unit and determine if obesity is the major causal antecedent of early joint replacement in patients with OA. METHODS We analysed the correlation between BMI and the age at which patients undergo total knee replacement (TKR) in 41 023 patients from the Australian Orthopaedic Association National Joint Replacement Registry. We then investigated the effect of BMI on pathological changes of the tibia plateau of knee joint in a representative subset of the registry. RESULTS 57.58% of patients in Australia who had TKR were obese. Patients with overweight, obese class I & II or obese class III received a TKR 1.89, 4.48 and 8.08 years earlier than patients with normal weight, respectively. Microscopic examination revealed that horizontal fissuring at the osteochondral interface was the major pathological feature of obesity-related OA. The frequency of horizontal fissure was strongly associated with increased BMI in the predominant compartment. An increase in one unit of BMI (1 kg/m2) increased the odds of horizontal fissures by 14.7%. 84.4% of the horizontal fissures were attributable to obesity. AXL1717 Reduced cartilage degradation and alteration of subchondral bone microstructure were also associated with increased BMI. CONCLUSIONS The key pathological feature in OA patients with obesity is horizontal fissuring at the osteochondral unit interface. Obesity is strongly associated with a younger age of first TKR, which may be a result of horizontal fissures. © Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY-NC.

This systematic review with meta-analyses synthesises results from free living interventions targeting reductions in sedentary behaviour alone or combined with increases in physical activity. METHODS Six electronic databases were searched up to August 2019 for sedentary behaviour interventions in adults lasting for ≥7 days publishing cardiometabolic biomarker outcomes covering body anthropometry, blood pressure, glucose and lipid metabolism, and inflammation (54 studies). The pooled effectiveness of intervention net of control on 15 biomarker outcomes was evaluated using random effects meta-analyses in the studies with control groups not providing other relevant interventions (33 studies; 6-25 interventions analysed). RESULTS Interventions between 2 weeks and 0.05) were also small, and beneficial in direction except for fat-free mass (≈ 0.0 kg). Heterogeneity ranged widely (I2=0.0-72.9). CONCLUSIONS Our review of interventions targeting sedentary behaviour reductions alone, or combined with increases in physical activity, found evidence of effectiveness for improving some cardiometabolic risk biomarkers to a small degree. There was insufficient evidence to evaluate inflammation or vascular function. Key limitations to the underlying evidence base include a paucity of high-quality studies, interventions lasting for ≥12 months, sensitive biomarkers and clinical study populations (eg, type 2 diabetes).

Evidence suggests that large-scale infrastructure and built-environment initiatives to promote cycling are likely to be necessary but not sufficient to maximise cycling participation. Smaller-scale initiatives that can be implemented by organisations (eg, employers) and groups (eg, community groups) are therefore also important, but the full range of feasible activities to promote cycling is not known. We aimed to scope the literature and map organisational, social and individual level activities to increase cycling. METHODS Design Scoping review following an established five-stage process.Eligibility criteria Studies or publicly available reports describing cycling promotion initiatives deemed feasible for organisations or groups to implement.Sources of evidence and selection (i) online databases (Ovid (Medline), Ovid (Embase), SportDISCUS (Ebscohost), ProQuest, Web of Science), (ii) existing systematic reviews, (iii) expert stakeholder consultation. RESULTS We extracted data from 129 studies and reports, from 20 different countries, identifying 145 cycling promotion initiatives. From these initiatives we identified 484 actions within 93 action types within 33 action categories under the nine intervention functions described by Michie et al. Environmental restructuring (micro-level), enablement, education and persuasion were the functions with the most action types, while coercion, modelling and restriction had the fewest action types. CONCLUSION This is the first comprehensive map to summarise the broad range of action types feasible for implementation within organisation/group-based cycling promotion initiatives. The map will be a critical tool for communities, employers, practitioners and researchers in designing interventions to increase cycling. © Author(s) (or their employer(s)) 2020.

Coadministration of opioids and benzodiazepines is a risk factor for overdose. Few studies have evaluated leveraging pharmacists to address opioid-benzodiazepine coprescribing. Our aim was to develop and test a role for pharmacists as opioid stewards, to reduce opioid and benzodiazepine doses in coprescribed patients. We conducted Plan-Do-Study-Act cycles between November 2017 and May 2018 across two primary care centre clinics. A third clinic acted as a control. Our intervention included a pharmacist (1) identifying patients through medical record queries; (2) developing care plans; (3) discussing recommendations with physicians and (4) discussing implementing recommendations. We refined the intervention according to patient and physician feedback. At the intervention clinics, the number of patients with pharmacist developed care plans increased from less than 20% at baseline to over 60% postintervention. There was also a fourfold increase in thiazepine coprescribing. © Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY-NC. No commercial re-use. See rights and permissions.

In 2016, a self-referral system was introduced to the abortion service in Edinburgh, Scotland, as an option for women. Women could telephone a dedicated phone line during office hours and speak to an administrative assistant working in the abortion service who provided them the next available appointment to be seen in the service. This study aimed to evaluate a self-referral service to abortion by investigating its impact on women's experiences of the referral process. METHODOLOGY 21 semistructured interviews of women attending a specialist abortion service in Edinburgh, Scotland, were conducted. Interviews were transcribed verbatim and thematically analysed. The interviews focused on women's experience of the referral process. RESULTS Three main themes arose from the interviews, including reasons for choosing self-referral, experience of self-referral and challenges to using self-referral. Reasons for choosing self-referral were related to convenience, privacy and autonomy. Women found the experience of self-referral to be pleasant, non-judgemental and patient-centred, and self-referral prepared them for the appointment at the specialist abortion service. However, some women felt rushed, and self-referral made them anxious to attend the appointment. Challenges were difficulty with getting through on telephone lines, varying levels of support required for different individuals and awareness about the option of self-referral. CONCLUSION Women valued the option of self-referral. Women felt that the service should be expanded to increase availability,and promoted to women more widely within the community . © Author(s) (or their employer(s)) 2020. No commercial re-use.

However, their presence during the early steps of human liver carcinogenesis remains unknown. We thus aimed to determine whether TLS are induced in preneoplastic/early hepatic lesions, and if they are associated with a particular immune profile. EXPERIMENTAL DESIGN A series of 127 early hepatic lesions (EHL) (low/high grade dysplastic nodules, early HCC and small and progressed HCC) was included in the study. TLS were investigated by pathological reviewing. Densities of immune cells were assessed using immunohistochemistry. A subset of lesions was microdissected and gene expression profiling was performed with a custom Nanostring panel. RESULTS Compared to surrounding cirrhotic nodules, EHL of all stages displayed increased densities of T cells, B cells and dendritic cells. link2 Immature Tertiary lymphoid structures (TLS) were identified in 24% of EHL. Gene expression profiling identified a subset of EHL with elevated mRNA levels of various cytokines involved in immune cells recruitment and TLS induction. This subgroup of EHL also showed overexpression of genes related to T and B cells activation and antigen presentation as well as those related to immunosuppression and immune exhaustion. link3 CONCLUSIONS Local immune activation occurs in the very early steps of liver carcinogenesis, however it may not be fully efficient and paradoxically favor immune evasion and progression to full-blown HCC. These results have implications for the development of anti-HCC chemo-preventive strategies in cirrhotic patients. Copyright ©2020, American Association for Cancer Research.
