Abstract	Background: Domestic violence (DV) worsened during COVID-19 and Family Justice Centers (FJCs) were, even more so than before, a critical part of providing services to DV victims. This study characterizes the clinical and sociodemographic features of the clients that come to the Ventura County FJC (VCFJC) and examines the effect of COVID-19, thus informing awareness of services available to victims of DV. Methods: This was a retrospective cohort study utilizing the VCFJC database from 2019 to 2021. All client data normally collected was studied. A comparison of pre-COVID and post-COVID data was also conducted. Results: There were 3488 client entries. Clients were mostly female (79% [2755]; n = 3488), aged 25-40 (31.73% [1106]; n = 3448), white/Caucasian (44.42% [1531]; n = 3448) or Hispanic/Latinx (42.41% [1462]; n = 3448). Clients most often requested restraining orders (72.41% [2496]; n = 3448), and most commonly reported DV [physical] (47.90% [1651]; n = 3448). Most health-insured clients were covered by MediCal (45.06% [1231]; n = 2732). Pre- and post-COVID analysis showed the highest increases in DV [physical] (odds ratio = 1.26, Discussion: In serving clients affected by DV, FJCs are an important service for health care providers to be aware of. Post-COVID, clients reported DV and stalking/harassment at much higher percentages, which is consistent with national studies on the pandemic. The most alarming finding was the steep decrease in Initial Service Requests.

Abstract	Background: Intentional injuries are the second leading cause of death in the U.S. between the ages of 1 and 44. Each traumatic event is approached best with a multiagency and multidisciplinary approach. Family Justice Centers (FJCs) are structured as one-stop centers for victims of all forms of violence to provide services. Objective: The purpose of this study is to describe trauma patients evaluated in an FJC and determine the effect of the referrals on injury-related hospital recidivism. Method: This is a cross-sectional descriptive study of traumatically injured patients that were evaluated in an adult level II trauma center for 3 years and were referred to Ventura County's FJC. Results: There were 415 trauma admissions for intentional injuries, which accounted for 10.4% of the total trauma-related hospital admissions. Of these patients, 203 (49%) were evaluated in Ventura County's FJC. The remaining 212 (51%) had an open judicial case, thus, were not processed through the FJC due to conflict of interest. The mechanisms of injuries of patients that were evaluated at the FJC (N = 203) were mostly assaults (83%). Majority of the patients were of the Hispanic race (70%), males (69%), English speaking (77%), and aged 18-59 (84%). 573 individual services were provided to these patients. The patients evaluated through the FJC (N = 203) had zero recidivism, while those with open cases had a 1% recidivism rate (P = NS). Conclusion: By collaborating with FJCs, trauma center outcomes contribute to a pathway for healing and may prevent future acts of intentional injuries.

Abstract	How can public policy best deal with infectious disease? In answering this question, scholarship on the optimal control of infectious disease adopts the model of a benevolent social planner who maximizes social welfare. This approach, which treats the social health planner as a unitary "public health brain" standing outside of society, removes the policymaking process from economic analysis. This paper opens the black box of the social health planner by extending the tools of economics to the policymaking process itself. We explore the nature of the economic problem facing policymakers and the epistemic constraints they face in trying to solve that problem. Additionally, we analyze the incentives facing policymakers in their efforts to address infectious diseases and consider how they affect the design and implementation of public health policy. Finally, we consider how unanticipated system effects emerge due to interventions in complex systems, and how these effects can undermine well-intentioned efforts to improve human welfare. We illustrate the various dynamics of the political economy of state responses to infectious disease by drawing on a range of examples from the COVID-19 pandemic.

Abstract	Background: Efforts to maintain sinus rhythm in patients with persistent atrial fibrillation (PsAF) remain challenging, with suboptimal long-term outcomes. Methods: All patients undergoing convergent PsAF ablation at our centre were retrospectively analysed. The Atricure Epi-Sense® system was used to perform surgical radiofrequency ablation of the LA posterior wall followed by endocardial ablation. Results: A total of 24 patients underwent convergent PsAF ablation, and 21 (84%) of them were male with a median age of 63. Twelve (50%) patients were obese. In total, 71% of patients had a severely dilated left atrium, and the majority (63%) had preserved left ventricular function. All were longstanding persistent. Eighteen (75%) patients had an AF duration of >2 years. There were no endocardial procedure complications. At 36 months, all patients were alive with no new stroke/transient ischaemic attack (TIA). Freedom from documented AF at 3, 6, 12, 18, 24, and 36 months was 83%, 78%, 74%, 74%, 74%, and 61%, respectively. There were no major surgical complications, with five minor complications recorded comprising minor wound infection, pericarditic pain, and hernia. Conclusions: Our data suggest that convergent AF ablation is effective with excellent immediate and long-term safety outcomes in a real-world cohort of patients with a significant duration of AF and evidence of established atrial remodelling. Convergent AF ablation appears to offer a safe and effective option for those who are unlikely to benefit from existing therapeutic strategies for maintaining sinus rhythm, and further evaluation of this exciting technique is warranted. Our cohort is unique within the published literature both in terms of length of follow-up and very low rate of adverse events.

Abstract	Introduction: Polycystic ovary syndrome (PCOS) seems to be associated with increased ovarian sympathetic nerve activity and in rodent models of PCOS reducing the sympathetic drive to the ovary, through denervation or neuromodulation, improves ovulation rate. We hypothesised that sympathetic nerves work with gonadotropins to promote development and survival of small antral follicles to develop a polycystic ovary phenotype. Methods: Using a clinically realistic ovine model we showed a rich sympathetic innervation to the normal ovary and reinnervation after ovarian transplantation. Using needlepoint diathermy to the nerve plexus in the ovarian vascular pedicle we were able to denervate the ovary resulting in reduced intraovarian noradrenaline and tyrosine hydroxylase immunostained sympathetic nerves. We developed an acute polycystic ovary (PCO) model using gonadotrophin releasing hormone (GnRH) agonist followed infusion of follicle stimulating hormone (FSH) with increased pulsatile luteinising hormone (LH). This resulted in increased numbers of smaller antral follicles in the ovary when compared to FSH infusion suggesting a polycystic ovary. Results: Denervation had no effect of the survival or numbers of follicles in the acute PCO model and did not impact on ovulation, follicular and luteal hormone profiles in a normal cycle. Discussion: Although the ovary is richly inervated we did not find evidence for a role of sympathetic nerves in ovarian function or small follicle growth and survival.

Abstract	We examined the learning curve of Motec total wrist arthroplasty (TWA) of six experienced surgeons in their first 30 cases. Three times more complications/revisions were encountered in the first half of the study compared with the second half. Motec TWA surgery should be concentrated in a smaller number of centres performing higher volumes.

Abstract	The aim of this study was to analyse the short- and medium-term complications of the Motec total wrist arthroplasty (TWA). Identifying exact modes of failure and their causes should allow surgeons to avoid or mitigate these risks in the future. Retrospective analysis of prospectively collected data from six hand surgeons at five international centres provided details of 171 Motec TWAs. The mean follow-up was 5.8 years (range 18 months to 12 years). There were 33 (19%) complications within our cohort, with a revision rate of 8.2% (14 revisions). There was no difference in complication rates between metal-on-metal and metal-on-polymer articulations. Failure of osseointegration was the most common complication. Problems with soft tissue balancing, implant impingement related osteolysis, bony impingement and metacarpal fracture were found to be other preventable causes of failure in this series. Elimination of these preventable complications will improve survival rates for this implant.

Abstract	Background: Contemporary models of non-suicidal self-injury (NSSI) suggest that emotional vulnerabilities, negative self-schemas, and beliefs about NSSI work together to differentiate students who self-injure from those who do not. However, it is unclear how these mechanisms are differentially related among students with and without a history of NSSI. Considering this, we used a network analysis approach to explore how students with and without a history of NSSI vary in processing their emotional experiences in relation to their self-concepts and beliefs about NSSI. Method: A sample of 480 university students (M Results: A network comparison test revealed that students with a history of NSSI perceived themselves to have difficulties regulating particularly intense, unwanted negative emotions. In light of this, students with a history of NSSI expected some benefits of NSSI (e.g., emotion regulation) regardless of potential barriers (e.g., pain). Conversely, for students without a history of NSSI, expecting NSSI to have aversive outcomes was tied to expecting NSSI to have few benefits. Limitations: The cross-sectional design limits inferences to be made about the network structures. Conclusions: Students with and without a history of NSSI appear to differ in their cognitive processing of negative emotions and strategies used to deal with these emotions.
