Background Enamel etching is of utmost importance during the orthodontic bonding procedure. Phosphoric acid, hydrofluoric acid, and citric acid are used in specific concentrations to create surface irregularities on enamel surfaces, enhancing the bond strength of the orthodontic attachment. Therefore, it is essential to evaluate the type of etchant for reliable orthodontic bracket bonding with minimal damage to the enamel surface. Aims and objectives This study aimed to investigate the morphological changes on the enamel surface after treatment with different surface etchants, assess the depth of penetration, and evaluate the shear bond strength (SBS) of orthodontic brackets...

PURPOSE: Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is associated with a 1-8% risk of post-biopsy sepsis (PBS). A recent study described an isopropyl alcohol needle washing protocol that significantly decreased PBS rates. The current study examined the efficacy of this technique in our clinic population. MATERIALS AND METHODS: Data were reviewed for 1250 consecutive patients undergoing TRUS-Bx at the Charlie Norwood VA Medical Center from January 2017 to January 2023...

Dopamine (DA) signaling is critically important in striatal function, and this metabolically demanding process is fueled largely by glucose. However, DA and glucose are typically studied independently and, as such, the precise relationship between DA release and glucose availability remains unclear. Fast-scan cyclic voltammetry (FSCV) is commonly coupled with carbon-fiber microelectrodes to study DA transients. These microelectrodes can be modified with glucose oxidase (GOx) to generate microbiosensors capable of simultaneously quantifying real-time and physiologically relevant fluctuations of glucose, a nonelectrochemically active substrate, and DA, which is readily oxidized and reduced at the electrode surface...

Arterial duct stenting, pioneered in the early 1990s for newborns with a duct-dependent pulmonary and systemic circulation, has evolved significantly over the past decades. This progressive technique has led to the development of novel therapeutic strategies, including the Hybrid approach introduced three decades ago, and more recently, a complete transcatheter approach for treating newborns with hypoplastic left heart syndrome (HLHS). Subsequently, the transcatheter method has been extended to bi-ventricular lesions and patients with pulmonary hypertension, establishing a reverse Potts-shunt pathophysiology...

UNLABELLED: We present three cases of hypoplastic left heart syndrome (HLHS) complicated by congenital esophageal atresia and trachea-esophageal fistula (EA/TEF). The standard treatment for HLHS involves a staged surgical approach, eventually reaching Fontan completion. There is no report of patients with both HLHS and EA/TEF, and no established treatment strategy exists for such cases. Given the significant risk of simultaneously operating on HLHS and EA/TEF, we elected to pursue staged repair for each condition separately...

High silica contents rubber composites are favored in the green tire industry for their ability to reduce rolling resistance. However, achieving effective silica dispersion in natural rubber, particularly at high silica content, poses a challenge. In addition, the choice of impeller configuration significantly influences mixing performance, especially in commercial production, which requires large mixing tanks. Therefore, understanding the scaling-up process for this mixing system is essential. This research aims to investigate the mixing of silica dispersion in natural latex, specifically focusing on a high silica content regime...

This paper presents research on several factors influencing the stabbing behaviour of stratified panels made of aramid fabric Twaron® SRM509 Teijin Aramid BV (Arnhem, The Netherlands). The inputs in the test campaign were the number of layers, the impact energy, and the sample size. Tests were performed on small samples (130 mm × 130 mm) on an Instron® CEAST 9350 drop-tower impact system (Norwood, MA, USA) and on larger samples (400 mm × 400 mm) using a test installation with the same values of the impact energy...

OBJECTIVES: The primary objectives were to examine utilization of the Hybrid versus the Norwood procedure for patients with hypoplastic left heart syndrome or variants and the impact on hospital mortality. The Hybrid procedure was 1st used at our institution in 2004. METHODS: Review of all subjects undergoing the Norwood or Hybrid procedure between 1 January 1984 and 31 December 2022. The study period was divided into 8 eras: era 1, 1984-1988; era 2, 1989-1993; era 3, 1994-1998; era 4, 1999-2003; era 5, 2004-2008; era 6, 2009-2014; era 7, 2015-2018 and era 8, 2019-2022...

BACKGROUND: Acute kidney injury is a common postoperative complication of paediatric cardiac surgery associated with increased morbidity and mortality. The purpose of this study is to characterise associations between haemodynamic parameters, clinical parameters, and medical interventions, on acute kidney injury. METHODS: Nine patients with univentricular physiology undergoing the Norwood procedure from a single-centre tertiary care paediatric cardiac ICU were included (September 2022 to March 2023)...

OBJECTIVES: Patients after the Norwood procedure are prone to postoperative instability. Extracorporeal membrane oxygenation (ECMO) can help to overcome short-term organ failure. This retrospective single-center study examines ECMO weaning, hospital discharge and long-term-survival after ECMO-therapy between Norwood and bidirectional Glenn (BDG) palliation as well as risk factors for mortality. METHODS: In our institution over 450 Norwood procedures have been performed...

IMPORTANCE: There has been increased interest in low-dose oral minoxidil for androgenetic alopecia (AGA) treatment. However, the efficacy of oral minoxidil for male AGA is yet to be evaluated in comparative therapeutic trials. OBJECTIVE: To compare the efficacy, safety, and tolerability of daily oral minoxidil, 5 mg, vs twice-daily topical minoxidil, 5%, for 24 weeks in the treatment of male AGA. DESIGN, SETTING, AND PARTICIPANTS: This double-blind, placebo-controlled randomized clinical trial was conducted at a single specialized clinic in Brazil...

BACKGROUND: Celiac disease (CeD) is an immune-mediated disorder affecting the small bowel, associated with genetic factors and increasing global prevalence.

METHODS: An anonymised database including 26,607 patients was subjected to analysis...

Black and Latinx people are disproportionately impacted by HIV, COVID-19, and other syndemic health crises with similar underlying social determinants of health. Lessons learned from the HIV pandemic and COVID-19 response have been invoked to improve health equity at the systemic level in the face of other emergent health crises. However, few have examined the potential translation of strategies between syndemics at the individual level. The current mixed-methods study examined strategies used to manage HIV during the COVID-19 pandemic and the extent to which they were helpful in managing COVID-19 vulnerability among Black and Latinx people living with HIV...

Like other minoritized populations, American Indian/Alaska Native (AI/AN) females experience disparate morbidity and mortality outcomes to that of the general US population. This study identified discrepancies in reporting of AI/AN female decedents between the North Carolina Violent Death Reporting System (NC-VDRS) and an online, user-generated database. Female AI/AN decedent data of all ages were collected from the NC-VDRS and compared against that of the publicly available North Carolina Missing and Murdered Indigenous Women (MMIW NC) database for the study period, 2004-2019...
