Ferroptosis is a newly identified and novel form of cell death, which is characterized by an iron- and reactive oxygen species (ROS)-dependent manner. Potential utility of ferroptotic cell death has been recently proposed for cancer treatment. Meanwhile, ROS generation and apoptosis are inherently consequent to cell apoptosis and dysfunction during islet cell preparation and transplantation. Whether ferroptosis induction is a regulator for cell viability and function in human pancreatic islet-cell clusters (ICCs) derived from pancreatic progenitor cells (PPCs) remains elusive. We thus sought to induce ferroptosis in our established cell culture system of human PPCs/ICCs, examine the effects of ferroptosis on ICCs, and explore the potential regulatory pathways involved. Our results showed that ICCs were prone to the use of ferroptosis-inducing and inhibiting agents under our culture conditions. Erastin, a ferroptosis inducer, was found to trigger ferroptosis in ICCs, without the apparent detection of other types of cell death involved, such as apoptosis and autophagy. BP1102 In corroboration, the use of ferroptosis inhibitor, ferrostatin-1 (Fer-1), was found to enhance the cell viability of ICCs and prevent them from ferroptosis as well as improve its function. Mechanistically, the erastin-induced ferroptosis in ICCs was probably mediated via activation of JNK/P38/MAPK pathways and upregulation of NOX4 expression. Together, our findings may provide a scientific basis of ferroptosis inhibition as a potential for the amelioration of ICC survival and functionality during islet transplantation in diabetic patients.Background Anticoagulants continue to pose high risk of harm to patients despite the discovery of novel direct-acting oral anticoagulant agents that require less monitoring than warfarin. Objective To evaluate patients' knowledge about their oral anticoagulants and the potential role for community pharmacists in optimising safety. Setting Community pharmacies in England. Methods An online survey-based evaluation conducted over a 5-month period to ascertain patients' knowledge, use of anticoagulant alert cards, compliance with national monitoring requirements for warfarin, and frequency and nature of community pharmacist involvement in optimisation. Differences between patients on direct-acting oral anticoagulant agents and warfarin were assessed using Chi squared tests. Main outcome measure Patients' knowledge and use of anticoagulant alert cards. Results A total of 1515 pharmacies participated. Of 22,624 patients, 97% knew that they were taking anticoagulants; 20% had alert cards with them at time of dispensing; 17% had no card and 10% refuted their usefulness. Patients on warfarin were more aware of interactions with over-the-counter or herbal medicines than those on direct-acting oral anticoagulant agents. Of the patients on warfarin, 82% confirmed monitoring in the previous 12 weeks in accordance with national standards, with the international normalised ratio value known for 76%. Pharmacists intervened in a fifth of the patients to issue an alert card, contact the general practitioner for a change in the prescription or due to interacting medicines. Conclusion Patients had reasonable knowledge of their anticoagulation therapy, but areas for improvement were identified. Community pharmacists are well placed to optimise the safe use of anticoagulants.This study examines administrator and stakeholder perspectives on factors influencing the sustainability of Problematic Sexual Behavior Cognitive Behavioral Therapy (PSB-CBT). After initial implementation of PSB-CBT, qualitative interviews (N = 42) on the sustainability of services were conducted with treatment program administrators (n = 10) and community stakeholders (n = 32) from six sites across the USA. Interviewees discussed key facilitators and barriers for sustainability and identified the following factors as impacting the sustainability of PSB-CBT public relations, policy, inter-agency collaboration, funding, and workforce issues. Results were overall consistent with the EPIS (Exploration, Preparation, Implementation, Sustainment) model for implementation in public service sectors, but proposed modifications are also noted. Findings underscore the value of qualitative research in identifying best practices for sustaining valuable therapeutic interventions. The authors argue that future efforts to sustain evidence-based interventions, especially those dealing with sensitive topics around which misinformation and stigma are associated, should prioritize public relations (i.e., outreach, education) in addition to the intervention.

Miniscrews are effective devices for performing upper incisor intrusion. Different mechanics can be applied depending on the treatment objectives. This study aimed to evaluate the efficacy of one or two anterior miniscrews for upper incisor correction in cases of overbite and angulation in adult patients.

Forty-four adults with deep overbite were divided into two groups group 1 was treated with one miniscrew between upper central incisors and group 2 with two miniscrews between upper lateral incisors and canines. Incisor intrusion and length were measured from lateral cephalograms before treatment, after treatment and at least 12 months into retention (T0, T1 and T2). Forces were applied (90 g) from the miniscrews to the archwire using elastomeric chains. ANOVA analysis was used to determine whether differences between evaluation times were statistically significant.

Mean root resorption was 2.15 ± 0.85 mm, which ceased after active treatment. Overbite mean correction was - 3.23 ± 1.73 mm with no statisuccal angulation is greater with one miniscrew. Root resorption is positively related to the extent of intrusion. Stability is satisfactory regardless of whether one or two miniscrews are used.

To evaluate the early findings of new monofocal intraocular lens (Tecnis

Eyhance) in comparison with standard monofocal intraocular lens (Tecnis

1-piece) in patients who underwent cataract surgery.

Sixty-four eyes of thirty-two patients (each intraocular lens model was implanted bilaterally in 16 patients) were included in this retrospective study. Preoperative and postoperative (at one month) manifest refraction, spherical equivalent (SE) values, monocular and binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UCIVA), distance-corrected intermediate visual acuity (DCIVA), distance-corrected near visual acuity (DCNVA), binocular defocus curve, photopic contrast-sensitivity, spectacle independence, photic phenomena, tolerance to residual refractive errors and complications were recorded.

The mean monocular postoperative UDVA, CDVA, DCNVA, spherical equivalent and cylinder values were comparable between each group (p > 0.
