Application of three-dimensional printing in the planning and execution of aortic aneurysm repair.

Introduction: The accuracy of fenestrations in stent grafts for complex aortic aneurysms and dissections can be significantly improved using three-dimensional (3D)-printed phantoms. Standardization is enhanced by using artificial intelligence (AI) for image pre-processing before 3D printing. These methods address fallacies in centerline image analysis and manual image pre-processing.

Changes in Negative Emotions Across Five Weeks of HRV Biofeedback Intervention were Mediated by Changes in Resting Heart Rate Variability.

Resting heart rate variability (HRV) is typically higher in those with better emotional well-being. In the current study, we examined whether changes in resting HRV mediated changes in negative emotions during a 7-week clinical trial of HRV biofeedback. Younger and older adults were randomly assigned to one of two daily biofeedback practices for 5 weeks: (1) engage in slow-paced breathing to increase the amplitude of oscillations in heart rate at their breathing frequency (Osc+); or (2) engage in self-selected strategies to decrease heart rate oscillations (Osc-).

A Territory-Wide Follow-Up of Primary and Secondary Extramammary Paget Disease of 2 Decades: Effects of Local Disease on Survival.

Introduction: Extramammary Paget disease (EMPD) is an uncommon malignant cutaneous neoplasm that are divided into primary and secondary forms. In this multicenter study, histologically proven cases of primary and secondary EMPD were reviewed for clinical outcomes with subgroup analysis for secondary EMPD.

Methodology: Cases of EMPD were identified from pathology report of the involved institutions over a period of over 2 decades.

Successful corneal endothelium preservation in the management of epithelial downgrowth with 5-fluorouracil injections and membranectomy.

A 74-year-old Chinese man underwent extracapsular cataract extraction in his right eye and developed a translucent iris membrane 4 months later. He was treated with two intracameral 5-FU injections and membranectomy at 2 weeks apart. At one year following the second membranectomy, the patient maintained a clear cornea without residual or recurrent membrane, an endothelial cell density of 1072 cell/mm, a visual acuity of 20/50 and a normal intraocular pressure.

Evaluating the Effectiveness of Laparoscopic Removal of an Accessory Spleen After a Failed Splenectomy for Immune Thrombocytopenia.

Immune thrombocytopenic purpura (ITP) is a challenging condition to manage especially when conventional treatment methods, including splenectomy, fail. This report evaluates the effectiveness of laparoscopic removal of accessory spleen for chronic refractory ITP after an initial splenectomy. A 73-year-old African American male with a history of ITP, previously treated with laparoscopic splenectomy nine years ago, presented with severe thrombocytopenia that was found to be refractory to medical therapies.

The Asian Fabry Cardiomyopathy High-Risk Screening Study 2 (ASIAN-FAME-2): Prevalence of Fabry Disease in Patients with Left Ventricular Hypertrophy.

Fabry disease (FD) is a rare X-linked lysosomal storage disorder that commonly manifests cardiovascular complications. We aimed to assess the prevalence of FD in a Chinese population with left ventricular hypertrophy (LVH) whilst implementing a gender-specific screening approach. Patients with LVH, defined as a maximum thickness of the left ventricular septal/posterior wall ≥ 13 mm, were considered eligible.

Two Cases of Malpositioning of Internal Jugular Central Venous Catheters: A Review of Literature and Current Treatment Recommendations.

Percutaneous central venous catheterization, despite ultrasound guidance, is known to carry significant risks. While central venous catheters are widely used in clinical practice, they are also associated with various complications, including incorrect positioning during insertion. Arterial puncture is a well-recognized complication, and although unintended subclavian or carotid artery cannulation is rare, it can lead to serious consequences.

Urological complications caused by inferior vena cava filters: a systematic review.

Introduction: Inferior vena cava (IVC) filters act in preventing pulmonary embolisms (PE). Various complications have been reported with their use. However, a credible urological complication rate, filter characteristics, and clinical presentation has yet to be summarized.

Heart rate and breathing effects on attention and memory (HeartBEAM): study protocol for a randomized controlled trial in older adults.

Background: In healthy people, the "fight-or-flight" sympathetic system is counterbalanced by the "rest-and-digest" parasympathetic system. As we grow older, the parasympathetic system declines as the sympathetic system becomes hyperactive. In our prior heart rate variability biofeedback and emotion regulation (HRV-ER) clinical trial, we found that increasing parasympathetic activity through daily practice of slow-paced breathing significantly decreased plasma amyloid-β (Aβ) in healthy younger and older adults.

Increased histological severity and chronicity of interface inflammation in anti-MDA5 dermatomyositis-A comparative dermatopathological analysis.

Anti-melanoma differentiation-associated gene 5 (MDA5) dermatomyositis is characterized by serological detection of anti-MDA5 antibody and rapidly progressive interstitial lung disease. In this study, the largest cohort of skin biopsies to date of anti-MDA5 dermatomyositis was reviewed and compared with cases of dermatomyositis with negative serology. Findings contribute to the histological diagnosis and evaluation of the severity of cutaneous inflammation in anti-MDA5 dermatomyositis.

Multimodal neuroimaging data from a 5-week heart rate variability biofeedback randomized clinical trial.

We present data from the Heart Rate Variability and Emotion Regulation (HRV-ER) randomized clinical trial testing effects of HRV biofeedback. Younger (N = 121) and older (N = 72) participants completed baseline magnetic resonance imaging (MRI) including T-weighted, resting and emotion regulation task functional MRI (fMRI), pulsed continuous arterial spin labeling (PCASL), and proton magnetic resonance spectroscopy (H MRS). During fMRI scans, physiological measures (blood pressure, pulse, respiration, and end-tidal CO) were continuously acquired.

Pre-Emptive Opioid-Sparing Medication Protocol Decreases Pain and Length of Hospital Stay in Children Undergoing Posterior Spinal Instrumented Fusion for Scoliosis.

Background: Poorly controlled post-operative pain following Posterior Spinal Instrumented Fusion (PSIF) for scoliosis may be associated with delayed ambulation and longer hospital stays. Multimodal analgesia use has been shown to provide superior analgesia with improved recovery and reduction of post-operative morbidity in other orthopedic subspecialties, but has not been described with pediatric patients undergoing spinal surgery.

Objective: We describe a novel, pre-emptive, opioid-sparing pediatric pain medication protocol that is started two days prior to surgery, in accordance with first-order pharmacokinetics, and continued post-operatively until discharge with the goal of decreasing post-operative pain, improving early mobilization, and ultimately decreasing the patient's length of hospital stay.

Mohs Surgery for Periocular Basal Cell Carcinoma Without a Mohs Surgeon: The First Series in Hong Kong.

Unlabelled: Purpose To report the first series of Mohs micrographic surgery (MMS) in Hong Kong, where the roles of a Mohs surgeon were shared and coordinated by a "mobile" surgeon.

Methods Design: Prospective non-comparative interventional case series.

Subjects: 20 consecutive Chinese patients (10 male, age 78.

Adolescent idiopathic scoliosis patients treated with bracing, surgery, or observation showed no difference in behavioral and emotional function over a 2-year period.

The purpose of this study was to assess if behavior and emotional function, as measured by the Pearson Behavioral Assessment Survey for Children, Second Edition (BASC-2) in patients and parents, changes with differing treatment protocols in patients with adolescent idiopathic scoliosis (AIS). One previous study showed abnormal BASC-2 scores in a substantial number of patients diagnosed with AIS; however, no study has assessed how these scores change over the course of treatment. AIS patients aged 12 to 21 years completed the BASC-2.

A rare presentation of pemphigus vegetans as an isolated vegetative lesion-Review of histopathological clues and treatment effects in multiple biopsy specimens.

Background: Pemphigus is a group of immunobullous dermatoses characterized by the presence of autoantibodies directed against adhesion molecules of keratinocytes, with pemphigus vegetans being the rarest form, accounting for 1%-2% of all cases of pemphigus. Pemphigus vegetans is characterized by verrucous vegetative lesions in addition to vesiculobullous lesions.

Methods: We report a rare case of pemphigus vegetans presenting as an isolated vegetative lesion in the groin 3 months prior to the development of blisters.

Heart rate variability (HRV) changes and cortical volume changes in a randomized trial of five weeks of daily HRV biofeedback in younger and older adults.

Previous studies indicate that the structure and function of medial prefrontal cortex (PFC) and lateral orbitofrontal cortex (OFC) are associated with heart rate variability (HRV). Typically, this association is assumed to reflect the PFC's role in controlling HRV and emotion regulation, with better prefrontal structural integrity supporting greater HRV and better emotion regulation. However, as a control system, the PFC must monitor and respond to heart rate oscillatory activity.

PRAME immunostain expression in sebaceous lesions, cutaneous carcinomas and adnexal structures.

The use of immunostain for PRAME antigen is well established for cutaneous melanolocytic lesions. However, its staining in other cutaneous structures and lesions is under reported. This study assessed PRAME staining in a large cohort of normal skin tissue, sebaceous lesions, and cutaneous carcinomas to better delineate patterns of PRAME immunoreactivity.

An Inkjet Printed Flexible Electrocorticography (ECoG) Microelectrode Array on a Thin Parylene-C Film.

Electrocorticography (ECoG) is a conventional, invasive technique for recording brain signals from the cortical surface using an array of electrodes. In this study, we developed a highly flexible 22-channel ECoG microelectrode array on a thin Parylene film using novel fabrication techniques. Narrow (<40 µm) and thin (<500 nm) microelectrode patterns were first printed on PDMS, then the patterns were transferred onto Parylene films via vapor deposition and peeling.

Designing reliable electrochemical cells for operando lithium-ion battery study.

Operando experiments attract increasing attention in lithium-ion batteries (LIBs) studies for their ability to capture non-equilibrium and fast-transient processes during electrochemical reactions. They provide valuable information and mechanisms that cannot be obtained from ex-situ methods. Designing a suitable and reliable electrochemical cell is the first crucial step for most operando studies.

Alkyl-Terminated Gold Nanoparticles as a Self-Therapeutic Treatment for Psoriasis.

We present a self-therapeutic nanoparticle for topical delivery to epidermal keratinocytes to prevent and treat psoriasis. Devoid of known chemical or biological antipsoriatic drugs, this sub-15 nm nanoparticle contains a 3 nm gold core and a shell of 1000 Da polyethylene glycol strands modified with 30% octadecyl chains. When it is applied to imiquimod-induced psoriasis mice without an excipient, the nanoparticle can cross the stratum corneum and preferentially enter keratinocytes.
