This style guide addresses critical aspects of IAs, including format, typography, color-coding, title brevity, patient identification, and introductory text.

Ascertainment of small airway dysfunction using oscillometry to better define asthma control and future risk: are we ready to implement it in clinical practice?

The small airways comprise generations 8 to 23 of the bronchial tree, consist of airways with an internal diameter <2mm, and are classically difficult to assess and treat in persistent asthma. Small airways dysfunction (SAD) is integral to the asthma management paradigm as it is associated with poorer symptom control, greater levels of type 2 inflammation, and has been proposed as a potential treatable asthma trait. Although identification of SAD by oscillometry has been found to be clinically useful in managing asthma, very few physicians, including specialists, use this technique as part of standard or adjunct evaluation of lung function to diagnose asthma, grade severity of airway obstruction, ascertain disease control or the risk for future exacerbations or to make management decisions.

A Systematic Review on the Effectiveness and Safety of Combining Biostimulators with Botulinum Toxin, Dermal Fillers, and Energy-Based Devices.

Introduction: Aesthetic medicine has evolved towards minimally invasive procedures, with biostimulators like Poly-L-Lactic Acid (PLLA), Calcium Hydroxylapatite (CaHA), and Polycaprolactone (PCL) gaining attention for their role in collagen induction, improving skin texture, elasticity, and volume. Combining these agents with other treatments-such as botulinum toxin, dermal fillers, and energy-based devices (e.g.

CT- and MRI-based Factors Associated with Rapid Growth in Early-Stage Hepatocellular Carcinoma.

Background Prediction of the tumor growth rates is clinically important in patients with hepatocellular carcinoma (HCC), but previous studies have presented conflicting results and generally lacked radiologic evaluations. Purpose To evaluate the percentage of rapidly growing early-stage HCCs in each Liver Imaging Reporting and Data System (LI-RADS) category and to identify prognostic factors associated with rapid growth. Materials and Methods Retrospective study of patients with risk factors for HCC and those with surgically proven early-stage HCC who underwent two or more preoperative multiphasic CT or MRI examinations between January 2016 and December 2020.

Introduction: This study investigated the physical, mechanical, and optical properties of 3-dimensional (3D) printing resins compared with thermoplastic materials to evaluate their suitability for the fabrication of orthodontic clear retainers.

Methods: Samples were prepared from thermoplastic sheets (Duran [Scheu-Dental GmbH, Iserlohn, Germany] and Zendura [Bay Materials LLC, Fremont, Calif]) and biocompatible 3D-printing resins (Dental LT Clear V2 [Formlabs Inc, Somerville, Mass] and OrthoFlex [Nextdent BV, Soesterberg, The Netherlands]) according to the manufacturer's instructions. The materials were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, and water sorption tests.

An electrolyte disturbance masquerading as a panic attack.

Because proton pump inhibitors (PPIs) are so commonly used, their safety and potential adverse reactions often are not considered. This article describes a patient whose paresthesias and severe muscle cramps were attributed to panic attacks but actually were caused by hypocalcemia secondary to PPI-induced hypomagnesemia. This case serves as a reminder that PPIs should be used cautiously and appropriately with consideration for regular monitoring of electrolytes and vitamin B12.

Physical Performance Effects Associated with a 16-Week Therapeutic Yoga Intervention in Survivors of Cancers in the South Texas Region: A Pilot Study.

Yoga is recognized as a complementary practice that improves physical, mental, and spiritual health in survivors of cancer. The present study assessed associations between a holistic approach and physical function for 30 survivors of cancer in south Texas. Cancer survivors (86% female) of diverse backgrounds (62% underrepresented minorities) performed a battery of physical function tests, including a 6-minute walk test, to assess cardiorespiratory function, isometric shoulder and elbow-flexor strength, dominant-arm grip strength, dominant-arm shoulder range of motion via inclinometer, sit-and-reach test to assess trunk and lower-extremity flexibility, and a 30-second sit-to-stand test to assess lower-extremity endurance.

Retrieval of fractured implant screw: A dental technique.

Removing a fractured implant screw, though a relatively rare occurrence, presents a significant challenge for clinicians. Protecting the internal surface of the implant from damage during the retrieval of the fractured fragment is critical to avoid additional complications. A novel, cost-effective, and conservative technique for retrieving fractured implant screws using a small-diameter dental prophylactic brush is described.

The Effect of Wildfires on Asthma and Allergies.

Climate change is a major driver of the frequency and severity of wildfires caused by extended periods of drought and hotter, drier weather superimposed on the legacy of fire suppression in the Mountain West of the United States. In recent years, increased wildfire smoke has negated the improvements in air quality made by clean energy transitions. Wildfire smoke is a complex mixture of gases and solids, a chief constituent of which is fine particulate matter (PM).

School Absenteeism and Neighborhood Deprivation and Threat: Utilizing the Child Opportunity Index to Assess for Neighborhood-Level Disparities in Passaic County, NJ.

Leveraging publicly available data about schools' absenteeism from the New Jersey Department of Education, the present study examined how neighborhood-level resource deprivation and violent crime related to chronic absenteeism in Passaic County's elementary, middle, and high schools. Results highlighted geographic disparities in Passaic County, New Jersey, whereby predominantly racial/ethnic, under-resourced, communities of color have significantly greater levels of resource deprivation and threat. Additionally, greater neighborhood-level resource deprivation and neighborhood violent crime were associated with higher rates and trajectories of absenteeism across three academic school years.

Imaging Findings and Management Strategies for Liver Masses in Children with Predisposition Disorders: A Review by the Pediatric LI-RADS Group.

Liver masses in children with underlying systemic disease or a predisposing syndrome can be benign or malignant, ranging from focal fat to hepatocellular carcinoma (HCC). Knowledge of the underlying condition, the pathophysiologic effect on the liver, and the development of liver disease and specific liver lesions allows radiologists to guide imaging with regard to modality and frequency and give recommendations for biopsy when appropriate. In some predisposition disorders, such as Beckwith Wiedemann spectrum, familial adenomatous polyposis syndrome, and tuberous sclerosis complex, established guidelines for imaging screening exist.
