Understanding the implications of BoNT-A immunoresistance from the aesthetic patient's viewpoint allows HCPs to better support patients throughout their aesthetic treatment journey.

The Role of Neurotoxins and Fillers in Affirmative Care in Gender Nonconforming Filipino Patients.

Objective: Gender nonconformity refers to individuals whose gender identity, roles, or expressions do not adhere to societal standards and norms. Affirmative care is an approach to healthcare delivery in which organizations, programs, and providers recognize, validate, and support the identity stated or expressed by the individuals served. This study examined the effects of nonsurgical interventions performed by dermatologists, specifically botulinum toxins (BoNTA) and dermal filler injections, on the physical and mental health of Filipino gender nonconforming individuals.

An augmented reality and high-speed optical tracking system for laparoscopic surgery.

While minimally invasive laparoscopic surgery can help reduce blood loss, reduce hospital time, and shorten recovery time compared to open surgery, it has the disadvantages of limited field of view and difficulty in locating subsurface targets. Our proposed solution applies an augmented reality (AR) system to overlay pre-operative images, such as those from magnetic resonance imaging (MRI), onto the target organ in the user's real-world environment. Our system can provide critical information regarding the location of subsurface lesions to guide surgical procedures in real time.

Causal factors in primary open angle glaucoma: a phenome-wide Mendelian randomisation study.

Primary open angle glaucoma (POAG) is a chronic, adult-onset optic neuropathy associated with characteristic optic disc and/or visual field changes. With a view to identifying modifiable risk factors for this common neurodegenerative condition, we performed a 'phenome-wide' univariable Mendelian randomisation (MR) study that involved analysing the relationship between 9661 traits and POAG. Utilised analytical approaches included weighted mode based estimation, the weighted median method, the MR Egger method and the inverse variance weighted (IVW) approach.

Which Combination is the Best? A Comparison of the Predictive Potential of Serum Biomarker Combinations to Diagnose Periprosthetic Joint Infection.

Background: Without a gold-standard test, recent periprosthetic joint infections (PJI) literature has explored the utility of combining serological results, with promising findings. However, previous studies evaluated fewer than 200 patients and often studied only 1 to 2 test combinations. The purpose of this study was to accumulate a large single-institution cohort of revision total joint arthroplasty (rTJA) patients to determine the diagnostic utility of combination serum biomarkers to identify PJI.

Pent-up demand for total shoulder arthroplasty prior to Medicare eligibility at age 65 years: evidence from a national patient database and national survey data.

Background: Rising utilization rates of total shoulder arthroplasty (TSA) paired with an aging US population herald increased future economic burden. Previous research has demonstrated evidence of "pent-up demand" in health care (delaying medical care until financially able) accompanying insurance status changes. The purpose of this study was to determine pent-up demand for TSA in the years leading up to Medicare coverage at age 65 years while identifying key drivers underlying this trend, including socioeconomic status.

Reasons and Risk Factors for Failed Same-Day Discharge After Primary Total Knee Arthroplasty.

Background: As ambulatory total knee arthroplasty (TKA) becomes increasingly common, unplanned admission after surgery presents a challenge for the health care system. Studies evaluating the reasons and risk factors for this occurrence are limited. We sought to evaluate the reasons for unplanned admission after surgery and identify risk factors associated with this occurrence.

Pharmacological Therapies for Connective Tissue Fibrosis in Orthopaedics.

Fibrosis is a common and debilitating pathological process that affects many organ systems and contributes to connective tissue disorders in orthopaedics. Tendons heal after acute and chronic injury through a process of fibrovascular scar tissue formation, and soft tissue joint capsules can be affected after traumatic joint injury, leading to arthrofibrosis. Although the precise underlying mechanisms are still being elucidated, fibrosis is thought to be a consequence of dysregulated immune and cytokine signaling that leads to myofibroblast activation and proliferation and subsequent excessive collagen deposition.
