RESUMO
Finding effective therapeutic targets to treat NRAS-mutated melanoma remains a challenge. Long non-coding RNAs (lncRNAs) recently emerged as essential regulators of tumorigenesis. Using a discovery approach combining experimental models and unbiased computational analysis complemented by validation in patient biospecimens, we identified a nuclear-enriched lncRNA (AC004540.4) that is upregulated in NRAS/MAPK-dependent melanoma, and that we named T-RECS. Considering potential innovative treatment strategies, we designed antisense oligonucleotides (ASOs) to target T-RECS. T-RECS ASOs reduced the growth of melanoma cells and induced apoptotic cell death, while having minimal impact on normal primary melanocytes. Mechanistically, treatment with T-RECS ASOs downregulated the activity of pro-survival kinases and reduced the protein stability of hnRNPA2/B1, a pro-oncogenic regulator of MAPK signaling. Using patient- and cell line- derived tumor xenograft mouse models, we demonstrated that systemic treatment with T-RECS ASOs significantly suppressed the growth of melanoma tumors, with no noticeable toxicity. ASO-mediated T-RECS inhibition represents a promising RNA-targeting approach to improve the outcome of MAPK pathway-activated melanoma.

OBJECTIVE: To determine the prevalence of 'spin' (i.e., reporting practices that distort the interpretation of results by positively reflecting negative findings or downplaying potential harms) strategies and level of spin in urological observational studies and whether the use of spin has changed over time. MATERIALS AND METHODS: MEDLINE and Embase were searched to identify observational studies comparing therapeutic interventions in the top five urology journals and major urological subspecialty journals, published between 2000 and 2001, 2010 and 2011, and 2020 and 2021. RESULTS: A total of 235 studies were included. Spin was identified in 81% of studies, with a median of two strategies per study. The most commonly used strategies were inadequate implication for clinical practice (30%), causal language or causal claim (29%), and use of linguistic spin (29%). Moderate to high levels of spin were found in 55% of conclusions. From 2000 to 2020, the average number of strategies used has significantly decreased each decade (H = 27.459, P < 0.001), and the median level of spin in conclusions was significantly lower in studies published in the 2020s and 2010s than in the 2000s (H = 11.649, P = 0.003). CONCLUSIONS: Our results suggest that 81% of urological observational studies comparing therapeutic interventions contained spin. Over the past two decades, the use of spin has significantly declined, but this remains an area for improvement, with 70% of included studies published in the 2020s employing spin. Medical writing should scrupulously avoid words or phrases that are not supported by data in the manuscript.

PURPOSE: "Spin" refers to a form of language manipulation that positively reflects negative findings or downplays potential harms. Spin has been reported in randomized controlled trials of other surgical specialties, which can lead to the recommendation of subpar or ineffective treatments. The goal of this study was to characterize spin strategies and severity in statistically nonsignificant urology randomized controlled trials. MATERIALS AND METHODS: A comprehensive search of MEDLINE and Embase for the top 5 urology journals, major urology subspecialty journals, and high-impact nonurology journals from 2019 to 2021 was conducted. Statistically nonsignificant randomized controlled trials with a defined primary outcome were included. Screening, data extraction, and spin assessment were performed in duplicate by 2 independent reviewers. RESULTS: From the database search of 4,339 studies, 46 trials were included for analysis. Spin was identified in 35 studies (76%), with the majority of abstracts (n = 26, 57%) and main texts (n = 35, 76%) containing some level of spin. "Obscuring the statistical nonsignificance of the primary outcome and focusing on statistically significant secondary results" was the most frequently used strategy in abstracts, while "other" strategies not previously defined were the most commonly used strategies in main texts. Moderate or high spin severity was identified in 21 (46%) abstract and 22 (48%) main text conclusions. CONCLUSIONS: Overall, our results suggest that 76% of statistically nonsignificant urology randomized controlled trials contained some level of spin. Readers and writers should be aware of common spin strategies when interpreting nonsignificant results and critically appraise the significance of results when making decisions for clinical practice.

Targeted delivery of nucleic acid therapeutics to the lungs could transform treatment options for pulmonary disease. We have previously developed oligomeric charge-altering releasable transporters (CARTs) for in vivo mRNA transfection and demonstrated their efficacy for use in mRNA-based cancer vaccination and local immunomodulatory therapies against murine tumors. While our previously reported glycine-based CART-mRNA complexes (G-CARTs/mRNA) show selective protein expression in the spleen (mouse, >99%), here, we report a new lysine-derived CART-mRNA complex (K-CART/mRNA) that, without additives or targeting ligands, shows selective protein expression in the lungs (mouse, >90%) following systemic IV administration. We further show that by delivering siRNA using the K-CART, we can significantly decrease expression of a lung-localized reporter protein. Blood chemistry and organ pathology studies demonstrate that K-CARTs are safe and well-tolerated. We report on the new step economical, organocatalytic synthesis (two steps) of functionalized polyesters and oligo-carbonate-co-α-aminoester K-CARTs from simple amino acid and lipid-based monomers. The ability to direct protein expression selectively in the spleen or lungs by simple, modular changes to the CART structure opens fundamentally new opportunities in research and gene therapy.
RESUMO
Individuals with borderline personality disorder (BPD) or antisocial personality disorder (ASPD) are overrepresented in forensic settings. Yet, despite the burden these disorders place on healthcare and criminal justice systems, there remains a lack of evidence-based pharmacological treatments. Epidemiological data have shown that comorbid cannabis use disorders are common in BPD and ASPD. ∆9 -Tetrahydrocannabinol, the primary psychoactive constituent of cannabis, is an exogenous cannabinoid that stimulates the endocannabinoid system (ECS). Hence, an investigation of the ECS in these conditions is warranted. This scoping review screened 105 records and summarized the extant research on the ECS in ASPD (n = 69) and BPD (n = 61) participants. Preliminary results suggest that alterations of the ECS may be present in these disorders. Although research examining the ECS in personality disorders is still in its infancy, more research is warranted given initial positive findings.

BACKGROUND: CBL-514 is a novel injectable drug that may be safe and efficacious for localized abdominal subcutaneous fat reduction. OBJECTIVES: The aim of this study was to assess the safety and efficacy of CBL-514 in reducing abdominal subcutaneous fat volume and thickness. METHODS: This Phase IIa, open-label, random allocation study consisted of a 6-week treatment period and follow-up at 4 and 8 weeks following the last treatment. Participants were randomly allocated to receive 1.2 mg/cm2 (180 mg), 1.6 mg/cm2 (240 mg), or 2.0 mg/cm2 (300 mg) of CBL-514 with up to 4 treatments, each comprising 60 injections into the abdominal adipose layer. Changes in abdominal subcutaneous fat were assessed by ultrasound at follow-up visits. Treatment-emergent adverse events were recorded. RESULTS: Higher doses of CBL-514 (unit dose, 2.0 and 1.6 mg/cm2) significantly improved the absolute and percentage reduction in abdominal fat volume (Pâ <â 0.00001) and thickness (Pâ <â 0.0001) compared with baseline. Although the COVID-19 pandemic halted some participant recruitment and follow-ups, analysis was unaffected, even after sample size limitations. CONCLUSIONS: CBL-514 injection at multiple doses up to 300 mg with a unit dose of 2.0 mg/cm2 is safe, well-tolerated, and reduced abdominal fat volume and thickness by inducing adipocyte apoptosis. Although other procedures exist to treat abdominal fat, they have limitations and may cause complications. At a dose of 2.0 mg/cm2, CBL-514 safely and significantly reduced abdominal fat volume by 24.96%, making it a promising new treatment for routine, nonsurgical abdominal fat reduction in dermatologic clinics.

PURPOSE: Craniopharyngioma is a rare low-grade neoplasm in children. Tumor progression occurs frequently, and survivors are at risk of long-term disease and treatment-related morbidities. We reviewed the population-based experience of managing pediatric craniopharyngioma in Hong Kong. METHODS: The Hong Kong Pediatric Hematology/Oncology Study Group database was interrogated for patients with craniopharyngioma younger than 18 years between 1999 and 2018. Patient demographics, clinical characteristics, outcomes, and long-term morbidities were summarized. RESULTS: Twenty-eight patients with craniopharyngioma were included (approximate incidence of 1.1 per 1,000,000 individuals). The treatment approaches were heterogeneous and included surgery only, surgery with adjuvant radiation, and surgery with intracystic interferon. With a median follow-up of 6.1 years, 12 (43%) patients experienced disease progression, and 3 patients died of progression, postoperative complication, and gastrointestinal bleeding. The 5-year progression-free survival (PFS) and overall survival (OS) rates were 56.8% (± 10.0%) and 92.0% (± 5.4%), respectively. The 10-year PFS and OS rates were 37.3% (± 11.4) and 92.0% (± 5.4%), respectively. Patients receiving treatment in a high-volume center had significantly better outcomes than did those treated at other centers (PFS, p = 0.007; OS, p = 0.029). Period of diagnosis, sex, age at diagnosis, greatest tumor dimension, extent of resection, and radiotherapy use did not significantly affect patient survival. Long-term visual impairment (60%) and endocrinopathies (92%) were common. CONCLUSION: Prognosis of pediatric craniopharyngioma in Hong Kong compares unfavorably with published reports. Centralization and standardization of treatment may prove valuable in mitigating patient outcomes.

The COVID-19 pandemic, originating in Wuhan, China, has become a major public health and economic challenge for countries around the world. As of May 08, 2020, there are over 3 million COVID-19 cases, and 250,000 COVID-19- associated deaths in 215 countries. As more data is collected, updated infection control measures are continuously released and published by government, public health authorities, and physician specialty associations. Across the globe, dermatological practices have had to limit their operations to varying degrees to facilitate disease control, but as the pandemic subsides, they will broaden their operations. In light of the uncertainty surrounding safe and effective practice of medical and aesthetic dermatology in the era of COVID-19, fourteen international experts in the field contributed to recommendations for effective infection control protocols and practice management modifications. While guidance from the World Health Organization and local public health officials comes first, these recommendations are crafted as a starting point for dermatologists worldwide to commence either reopening their doors to patients or expanding available service offerings. This can help ensure that patients receive needed care in the short term and improve long term practice viability. J Drugs Dermatol. 2020;19(7):e-1-e-9. doi:10.36849/JDD.2020.5293.

BACKGROUND: Asians increasingly seek non-surgical facial esthetic treatments, especially at younger ages. Published recommendations and clinical evidence mostly reference Western populations, but Asians differ from them in terms of attitudes to beauty, structural facial anatomy, and signs and rates of aging. A thorough knowledge of the key esthetic concerns and requirements for the Asian face is required to strategize appropriate facial esthetic treatments with botulinum toxin and hyaluronic acid (HA) fillers. METHODS: The Asian Facial Aesthetics Expert Consensus Group met to develop consensus statements on concepts of facial beauty, key esthetic concerns, facial anatomy, and aging in Southeastern and Eastern Asians, as a prelude to developing consensus opinions on the cosmetic facial use of botulinum toxin and HA fillers in these populations. RESULTS: Beautiful and esthetically attractive people of all races share similarities in appearance while retaining distinct ethnic features. Asians between the third and sixth decades age well compared with age-matched Caucasians. Younger Asians' increasing requests for injectable treatments to improve facial shape and three-dimensionality often reflect a desire to correct underlying facial structural deficiencies or weaknesses that detract from ideals of facial beauty. CONCLUSIONS: Facial esthetic treatments in Asians are not aimed at Westernization, but rather the optimization of intrinsic Asian ethnic features, or correction of specific underlying structural features that are perceived as deficiencies. Thus, overall facial attractiveness is enhanced while retaining esthetic characteristics of Asian ethnicity. Because Asian patients age differently than Western patients, different management and treatment planning strategies are utilized.

BACKGROUND: The desire for and use of nonsurgical injectable esthetic facial treatments are increasing in Asia. The structural and anatomical features specific to the Asian face, and differences from Western populations in facial aging, necessitate unique esthetic treatment strategies, but published recommendations and clinical evidence for injectable treatments in Asians are scarce. METHODS: The Asian Facial Aesthetics Expert Consensus Group met to discuss current practices and consensus opinions on the cosmetic use of botulinum toxin and hyaluronic acid (HA) fillers, alone and in combination, for facial applications in Southeastern and Eastern Asians. Consensus opinions and statements on treatment aims and current practice were developed following discussions regarding pre-meeting and meeting survey outcomes, peer-reviewed literature, and the experts' clinical experience. RESULTS: The indications and patterns of use of injectable treatments vary among patients of different ages, and among Asian countries. The combination use of botulinum toxin and fillers increases as patients age. Treatment aims in Asians and current practice regarding the use of botulinum toxin and HA fillers in the upper, middle, and lower face of patients aged 18 to[55 years are presented. CONCLUSIONS: In younger Asian patients, addressing proportion and structural features and deficiencies are important to achieve desired esthetic outcomes. In older patients, maintaining facial structure and volume and addressing lines and folds are essential to reduce the appearance of aging. This paper provides guidance on treatment strategies to address the complex esthetic requirements in Asian patients of all ages.

The palladium complex [(neocuproine)Pd(µ-OAc)]2[OTf]2 (1, neocuproine = 2,9-dimethyl-1,10-phenanthroline) is an effective catalyst precursor for the selective oxidation of primary and secondary alcohols, vicinal diols, polyols, and carbohydrates. Both air and benzoquinone can be used as terminal oxidants, but aerobic oxidations are accompanied by oxidative degradation of the neocuproine ligand, thus necessitating high Pd loadings. Several strategies to improve aerobic catalyst lifetimes were devised, guided by mechanistic studies of catalyst deactivation. These studies implicate a radical autoxidation mechanism initiated by H atom abstraction from the neocuproine ligand. Ligand modifications designed to retard H atom abstractions as well as the addition of sacrificial H atom donors increase catalyst lifetimes and lead to higher turnover numbers (TON) under aerobic conditions. Additional investigations revealed that the addition of benzylic hydroperoxides or styrene leads to significant increases in TON as well. Mechanistic studies suggest that benzylic hydroperoxides function as H atom donors and that styrene is effective at intercepting Pd hydrides. These strategies enabled the selective aerobic oxidation of polyols on preparative scales using as little as 0.25 mol % of Pd, a major improvement over previous work.

Background: As long-term, regular aesthetic botulinum neurotoxin A (BoNT-A) use becomes more commonplace, it is vital to understand real-world risk factors and impact of BoNT-A immunoresistance. The first Aesthetic Council on Ethical Use of Neurotoxin Delivery panel discussed issues relating to BoNT-A immunoresistance from the health care professionals' (HCPs') perspective. Understanding the implications of BoNT-A immunoresistance from the aesthetic patient's viewpoint allows HCPs to better support patients throughout their aesthetic treatment journey. Methods: A real-world consumer study surveyed 363 experienced aesthetic BoNT-A recipients across six Asia-Pacific territories. The survey mapped participants' BoNT-A aesthetic treatment journey and characterized awareness and attitudes relating to BoNT-A immunoresistance and treatment implications. At the second Aesthetic Council on Ethical use of Neurotoxin Delivery meeting, panelists discussed survey findings and developed consensus statements relating to the impact of BoNT-A immunoresistance on the aesthetic treatment journey. Results: Aesthetic BoNT-A patients' depth of knowledge about BoNT-A immunoresistance remains low, and risk/benefit communications need to be more lay-friendly. The initial consultation is the most important touchpoint for HCPs to raise awareness of BoNT-A immunoresistance as a potential side effect considering increased risk with repeated high-dose treatments. HCPs should be cognizant of differences across BoNT-A formulations due to the presence of certain excipients and pharmacologically unnecessary components that can increase immunogenicity. Standardized screening for clinical signs of secondary nonresponse and a framework for diagnosing and managing immunoresistance-related secondary nonresponse were proposed. Conclusion: These insights can help patients and HCPs make informed treatment decisions to achieve desired aesthetic outcomes while preserving future treatment options with BoNT-A.
RESUMO
Asians are of different ethnic origins. Nevertheless, they share the common facial structural deficiencies and consequences of the aging process that create the opportunity for esthetic intervention. As a result, Injectables are widely used in young Asians to achieve an oval facial shape with increased facial height and projection. In mature Asians with lifelong structural deficiencies, the beauty treatment plan is more complex than removal of signs of aging. Therefore, apart from injectables, other treatment modalities for tissue repositioning, neocollagenesis and skin quality improvement are also required to obtain the optimal result.

INTRODUCTION: Telemedicine has been shown to be a safe and effective modality to assess and treat patients with acute stroke who present to a community hospital. There are no previous reports on using telemedicine to treat patients with acute stroke who present to a comprehensive stroke center. We report here the outcomes of patients with acute stroke treated in 2021 at our comprehensive stroke center using telemedicine versus an in-person assessment. METHODS: Patients with acute ischemic stroke who were treated after either a telemedicine or in-person assessment at our hospital in 2021 were identified by a retrospective chart review. The primary outcomes collected were door-to-needle (DTN) time for alteplase (tPA) administration, door-to-puncture (DTP) time for endovascular thrombectomy, symptomatic intracranial hemorrhage (sICH) rates and 3-month mortality. RESULTS: There were 302 patients with acute stroke treated at our hospital in 2021. Of these, 18.2% (n = 55/302) were treated using telemedicine. There were no differences in any of the outcomes between patients treated using telemedicine versus an in-person assessment: DTN (35.5â min (n = 42) vs 33â min (n = 182), p < 0.76), DTP (86.5â min (n = 30) vs 85â min (n = 134), p < 0.97), sICH (0% (n = 0/55) vs 1.6% (n = 4/245, p < 0.59) or 3-month mortality (20.6% (n = 7/34) vs 22.1% (n = 40/181), p < 0.29). DISCUSSION: To the best of our knowledge, this is the first study to report on outcomes for acute stroke patients treated using telemedicine at a comprehensive stroke center. In this study, there were no differences in outcomes between patients treated using telemedicine versus an in-person assessment.
RESUMO
Pump-probe measurements by ultrashort THz pulses can be used to excite and follow the coherence dynamics in the time domain of single hydrogen molecules (H2) in the junction of a scanning tunneling microscope (STM). By tailoring the resonance frequency through the sample bias, we identified two spectral signatures of the interactions among multiple H2 molecules. First, the avoided level crossing featured by energy gaps ranging from 20 to 80 GHz was observed because of the level repulsion between two H2 molecules. Second, the tip can sense the signal of H2 outside the junction through the projective measurement on the H2 inside the junction, owing to the entangled states created through the interactions. A dipolar-type interaction was integrated into the tunneling two-level system model of H2, enabling accurate reproduction of the observed behaviors. Our results obtained by the quantum superposition microscope reveal the intricate quantum mechanical interplay among H2 molecules and additionally provide a 2D platform to investigate unresolved questions of amorphous materials.
RESUMO
Liquid handling robots are often limited by proprietary programming interfaces that are only compatible with a single type of robot and operating system, restricting method sharing and slowing development. Here we present PyLabRobot, an open-source, cross-platform Python interface capable of programming diverse liquid-handling robots, including Hamilton STARs, Tecan EVOs, and Opentron OT-2s. PyLabRobot provides a universal set of commands and representations for deck layout and labware, enabling the control of diverse accessory devices. The interface is extensible and can work with any robot that manipulates liquids within a Cartesian coordinate system. We validated the system through unit tests and several application demonstrations, including a browser-based simulator, a position calibration tool, and a path-teaching tool for complex movements. PyLabRobot provides a flexible, open, and collaborative programming environment for laboratory automation.
RESUMO
BACKGROUND: The unique anatomy of the Asian face, along with the influence of cultural forces and regional preferences, has led to the development of specialized approaches to rejuvenation and beautification that are applicable to the aesthetic practice within Asia as well as those who serve these patients internationally. AIMS: To discuss similarities and differences in anatomy and treatment preferences of Asian patients and explore how these differences may influence aesthetic practices. PATIENTS/METHODS: In support of clinicians who wish to serve a diverse patient population, a six-part international roundtable series focused on diversity in aesthetics was conducted from August 24, 2021 to May 16, 2022. RESULTS: The results of the sixth and final roundtable in the series, the Asian Patient, are described here. Anatomical differences and their influence on treatment preferences are discussed, and specific procedural information provided for management of facial shape and projection, including advanced injection techniques for the eyelid-forehead complex. CONCLUSIONS: The continued exchange of ideas and treatment techniques support not only optimal aesthetic outcomes for a diverse range of patients within a given practice, but also the evolution of aesthetic medicine. The expert approaches detailed here may be used to inform treatment plans tailored to the Asian population.
