The 1471 unique preprints were analyzed in-depth with regards to their orthopaedic specialty, research design, posting date and geographical origin. Preprints' citation counts, abstract views, tweets, and Altmetric scores were gathered, alongside the corresponding data from their eventual journal publications. We validated the publication of a pre-printed article by consulting PubMed, Google Scholar, and Dimensions (peer-reviewed databases), verifying that the title keywords and author matched the study's design and research question.
A substantial growth in orthopaedic preprints was observed, escalating from a low of four in 2017 to a high of 838 in 2020. Spine, knee, and hip ailments represented the most common focus of orthopaedic subspecialty practices. Between 2017 and 2020, the combined totals of pre-printed article citations, abstract views, and Altmetric scores showed an upward trend. Among the 1471 preprints analyzed, a matching publication was discovered in 762 (52%). The redundancy inherent in preprinting was reflected in the enhanced abstract views, citations, and Altmetric scores seen for articles that were also published in standard journals.
Although preprints represent a negligible percentage of overall orthopaedic research, our findings demonstrate an escalating distribution of preprinted, non-peer-reviewed articles in orthopaedic literature. Though possessing a narrower academic and public footprint than their published counterparts, these preprinted articles still access a substantial audience through rare and shallow online interactions; these do not come close to the engagement engendered by peer review. Additionally, the progression from posting a preprint to journal submission, acceptance, and ultimate publication is not explicitly defined by the available data on these preprint repositories. Hence, assessing whether preprinted article metrics are attributable to preprinting proves difficult, and studies of this type may tend to overstate the apparent impact of preprints. Even though preprint servers might provide a space for constructive commentary on research concepts, the current metrics for preprinted articles fail to show the substantial level of engagement achieved through peer review, in terms of either the volume or the quality of audience input.
The necessity for regulatory safeguards surrounding the dissemination of research through preprints is underscored by our investigation, a method that has not, thus far, yielded demonstrable improvements in patient care and hence, shouldn't be considered credible evidence by clinicians. In their commitment to patient well-being, clinician-scientists and researchers hold the primary responsibility of preventing harm from potentially inaccurate biomedical science. This commitment mandates prioritizing patient needs and utilizing the rigorous evidence-based process of peer review over preprints to ascertain scientific truths. We propose that journals publishing clinical research implement a policy similar to that of Clinical Orthopaedics and Related Research, The Bone & Joint Journal, The Journal of Bone and Joint Surgery, and the Journal of Orthopaedic Research, by barring the review of any paper that has been made public on a preprint server.
Our findings illuminate the need for protective measures in handling research disseminated via preprints, a channel without established patient benefit, and which should therefore not be treated as clinical evidence by physicians. By upholding the principles of evidence-based peer review, clinician-scientists and researchers assume the critical responsibility of protecting patients from potentially erroneous biomedical science. Their dedication to patient welfare must take precedence over relying on preprinting practices. In line with Clinical Orthopaedics and Related Research, The Bone & Joint Journal, The Journal of Bone and Joint Surgery, and the Journal of Orthopaedic Research, all journals publishing clinical research ought to discard any papers that were initially posted to preprint servers.
An essential component in initiating antitumor immunity is the immune system's precise identification and targeting of cancer cells. The insufficient presentation of tumor-associated antigens, due to the diminished expression of major histocompatibility complex class I (MHC-1) and the excessive expression of programmed death ligand 1 (PD-L1), causes the inactivation of T cells, resulting in poor immunogenicity. In this work, a dual-activatable binary CRISPR nanomedicine (DBCN) that effectively delivers a CRISPR system into tumor tissues and allows for precise activation control is described, aiming to remodel tumor immunogenicity. The DBCN is comprised of a thioketal-cross-linked polyplex core shielded by an acid-detachable polymer shell. This construction maintains stability during blood circulation, allowing the polymer shell to detach in tumor tissues to facilitate CRISPR system cellular internalization. Finally, exogenous laser irradiation triggers gene editing, enhancing therapeutic efficacy and mitigating safety concerns. DBCN effectively corrects the dysregulation of MHC-1 and PD-L1 expression in tumors through the collaborative action of multiple CRISPR systems, consequently stimulating robust T cell-dependent anti-tumor immunity to halt cancer growth, spread, and recurrence. With the amplified presence of CRISPR toolkits, this research proposes a desirable therapeutic approach and a universally applicable delivery system for the advancement of more sophisticated CRISPR-based cancer treatments.
An in-depth analysis and comparison of the outcomes associated with various methods of menstrual management, considering the chosen approach, its longevity, patterns of menstruation, rates of amenorrhea, effects on mood and feelings of dysphoria, and side effects experienced by transgender and gender-diverse adolescents.
All patients seen in the multidisciplinary pediatric gender program from March 2015 to December 2020, with a birth assignment as female, who experienced menarche and utilized a menstrual-management method, were the subject of a retrospective chart review. Data analysis included patient demographics, menstrual management persistence, bleeding frequency, side effects, and patient satisfaction scores at baseline (T1) and at one year (T2). FSEN1 Method subgroup-specific outcomes were compared to gauge the effect of these methods.
Ninety percent of the 101 patients in the sample group chose either oral norethindrone acetate or a 52-milligram levonorgestrel intrauterine device. Continuation rates for these methods remained consistent at both follow-up points. Almost all patients experienced an improvement in bleeding by T2, with 96% improvement in those using norethindrone acetate and 100% improvement in those using IUDs, without any variations noted between the various subgroups. In the first assessment (T1), norethindrone acetate exhibited an amenorrhea rate of 84% and IUDs an amenorrhea rate of 67%. At the second assessment (T2), these rates rose to 97% and 89% respectively, without any disparities between the treatment groups at either time point. Both follow-up assessments indicated a significant improvement in pain levels, along with improvements in mood and dysphoria related to menstruation for the majority of patients. FSEN1 There was no difference in the nature of side effects among the different subgroups. The groups' method satisfaction levels were identical at the T2 time point.
Norethindrone acetate or an LNG IUD was a common choice for menstrual management among patients. Consistent improvements in amenorrhea, decreased menstrual bleeding, and reduced pain, mood swings, and dysphoria were observed in all patients, indicating that menstrual management may be a practical intervention for gender-diverse individuals experiencing increased dysphoric reactions associated with menstruation.
In managing menstruation, most patients favored norethindrone acetate or an intrauterine device containing levonorgestrel. Continuation, amenorrhea, and enhanced management of bleeding, pain, and menstrually-related moods and dysphoria were observed consistently across all patients, proving the viability of menstrual management as an intervention for gender-diverse patients experiencing amplified dysphoria associated with menses.
The condition of pelvic organ prolapse (POP) involves the downward displacement of one or more vaginal components—the anterior, posterior, and apical—from their normal position. Pelvic organ prolapse, a widely encountered issue, affects up to half of women during their lifetime, detectable through examination. This article examines nonoperative POP management, including an evaluation and discussion for obstetrician-gynecologists, drawing on best practices from the American College of Obstetricians and Gynecologists, the American Urogynecologic Society, and the International Urogynecological Association. Determining POP requires a patient history that documents the existence and description of any symptoms, and explicitly identifies symptoms the patient feels are related to prolapse. FSEN1 The examination reveals the vaginal compartments affected and the severity of the prolapse. Patients experiencing symptomatic prolapse or requiring treatment for medical reasons are the only ones generally considered for treatment. Surgical approaches may be considered, but patients who are experiencing symptoms and want treatment should first receive non-surgical care, including pelvic floor physiotherapy or a trial with a pessary. Appropriateness, expectations, complications, and counseling points undergo a comprehensive review. Patients and ob-gyns can benefit from educational sessions that debunk common beliefs about bladder prolapse, urinary problems, and bowel difficulties in relation to prolapse. Enhancing patient education fosters a deeper comprehension of their medical condition, ultimately aligning treatment objectives and anticipations more harmoniously.
