Among the modalities used for treating skin aging, carboxytherapy has been introduced as a safe minimally-invasive method for rejuvenation, reparation, and reconditioning of the skin.

Objective: We assessed the efficacy of carboxytherapy for the treatment of intrinsic skin aging through pathological and immunohistochemical (IHC) investigations.

Reasons Not to Turf a Patient Whose "Belonging" in a Hospital Is Unclear.

Through the lens of metaphor and the arts, this article aims to illuminate how persons who are ill tarry through uncertainty to receive care, and, in response, clinicians must resist turfing such patients in a health system that often confers upon patients unclear criteria for belonging. In addition, this article considers relationships among clinicians, patients, and their loved ones through the perspectives of Maris and Ludlow, characters in the book, A Hospital Odyssey, by Gwyneth Lewis. The article suggests that engaged curiosity and empathy are helpful responses to clinical detachment, distraction, and disengagement.

Clinical Characteristics and Outcomes of Drug-Induced Acute Kidney Injury Cases.

Introduction: Drug-induced acute kidney injury (DI-AKI) is a frequent adverse event. The identification of DI-AKI is challenged by competing etiologies, clinical heterogeneity among patients, and a lack of accurate diagnostic tools. Our research aims to describe the clinical characteristics and predictive variables of DI-AKI.

Dopamine pathway and Parkinson's risk variants are associated with levodopa-induced dyskinesia.

Background: Levodopa-induced dyskinesia (LID) is a common adverse effect of levodopa, one of the main therapeutics used to treat the motor symptoms of Parkinson's disease (PD). Previous evidence suggests a connection between LID and a disruption of the dopaminergic system as well as genes implicated in PD, including and .

Objectives: To investigate the effects of genetic variants on risk and time to LID.

and P infectious keratitis: key bacterial mechanisms that mediate pathogenesis and emerging therapeutics.

Bacterial keratitis (bacterial infection of the cornea) is a major cause of vision loss worldwide. Given the rapid and aggressive nature of the disease, immediate broad-spectrum antibiotics are essential to adequately treat this disease. However, rising antibiotic resistance continues to accelerate, rendering many commonly used therapeutics increasingly ineffective.

Eat, Sleep, Console Approach or Usual Care for Neonatal Opioid Withdrawal.

Background: Although clinicians have traditionally used the Finnegan Neonatal Abstinence Scoring Tool to assess the severity of neonatal opioid withdrawal, a newer function-based approach - the Eat, Sleep, Console care approach - is increasing in use. Whether the new approach can safely reduce the time until infants are medically ready for discharge when it is applied broadly across diverse sites is unknown.

Methods: In this cluster-randomized, controlled trial at 26 U.

Diagnosis of Pregnancy Complications Using Blind Ultrasound Sweeps Performed by Individuals Without Prior Formal Ultrasound Training.

Objective: To estimate the diagnostic accuracy of blind ultrasound sweeps performed with a low-cost, portable ultrasound system by individuals with no prior formal ultrasound training to diagnose common pregnancy complications.

Methods: This is a single-center, prospective cohort study conducted from October 2020 to January 2022 among people with second- and third-trimester pregnancies. Nonspecialists with no prior formal ultrasound training underwent a brief training on a simple eight-step approach to performing a limited obstetric ultrasound examination that uses blind sweeps of a portable ultrasound probe based on external body landmarks.

When Is Iatrogenic Harm Negligent?

Iatrogenesis refers to harm experienced by patients resulting from medical care, whereas negligence is more narrowly conceived as deviation from standard care. While all harm resulting from negligence is iatrogenic, not all iatrogenic injury is negligent. This commentary on a case about a patient with a minoritized identity at the end of his life argues that criteria by which an iatrogenic injury is deemed negligent depend on how practice standards are defined.

Prehospital factors predict outcomes in pediatric trauma: A principal component analysis.

Background: Trauma team activation leveling decisions are complex and based on many variables. Accurate triage decisions improve patient safety and resource utilization. Our purpose was to establish proof-of-concept for using principal component analysis (PCA) to identify multivariate predictors of injury severity and to assess their ability to predict outcomes in pediatric trauma patients.

Hydrocortisone to Improve Survival without Bronchopulmonary Dysplasia.

Background: Bronchopulmonary dysplasia is a prevalent complication after extremely preterm birth. Inflammation with mechanical ventilation may contribute to its development. Whether hydrocortisone treatment after the second postnatal week can improve survival without bronchopulmonary dysplasia and without adverse neurodevelopmental effects is unknown.

Toolkit for Developing Structural Competency in Health Disparities in Allergy and Immunology Training and Research.

Resources to prepare Allergy and Immunology trainees and providers to recognize and address health disparities are lacking. We designed a curriculum using interactive sessions incorporating disease-specific, evidence-based content, and a panel-based workshop with facilitated discussion to prepare Allergy and Immunology trainees to identify structural racism and health disparities. Pre-session surveys revealed that a high portion of trainees reported feeling comfortable recognizing bias and discussing health equity (n = 16, mean = 3.

Patient and Health Care Worker Perceptions of Communication and Ability to Identify Emotion When Wearing Standard and Transparent Masks.

Importance: Adoption of mask wearing in response to the COVID-19 pandemic alters daily communication.

Objective: To assess communication barriers associated with mask wearing in patient-clinician interactions and individuals who are deaf and hard of hearing.

Design, Setting, And Participants: This pilot cross-sectional survey study included the general population, health care workers, and health care workers who are deaf or hard of hearing in the United States.

Phase 3 Safety and Efficacy of AZD1222 (ChAdOx1 nCoV-19) Covid-19 Vaccine.

Background: The safety and efficacy of the AZD1222 (ChAdOx1 nCoV-19) vaccine in a large, diverse population at increased risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the United States, Chile, and Peru has not been known.

Methods: In this ongoing, double-blind, randomized, placebo-controlled, phase 3 clinical trial, we investigated the safety, vaccine efficacy, and immunogenicity of two doses of AZD1222 as compared with placebo in preventing the onset of symptomatic and severe coronavirus disease 2019 (Covid-19) 15 days or more after the second dose in adults, including older adults, in the United States, Chile, and Peru.

Results: A total of 32,451 participants underwent randomization, in a 2:1 ratio, to receive AZD1222 (21,635 participants) or placebo (10,816 participants).

Malnourishment-Associated Acetaminophen Toxicity in Pregnancy.

Background: Although acetaminophen is commonly used in pregnancy, it can deplete glutathione concentrations and cause accumulation of 5-oxoproline, with subsequent metabolic acidosis.

Case: A malnourished 25-year-old woman, G2P1001, with chronic acetaminophen use presented with abdominal pain and high anion gap metabolic acidosis. After ruling out other potential causes, her urine 5-oxoproline level was found to be elevated.

Higher or Lower Hemoglobin Transfusion Thresholds for Preterm Infants.

Background: Limited data suggest that higher hemoglobin thresholds for red-cell transfusions may reduce the risk of cognitive delay among extremely-low-birth-weight infants with anemia.

Methods: We performed an open, multicenter trial in which infants with a birth weight of 1000 g or less and a gestational age between 22 weeks 0 days and 28 weeks 6 days were randomly assigned within 48 hours after delivery to receive red-cell transfusions at higher or lower hemoglobin thresholds until 36 weeks of postmenstrual age or discharge, whichever occurred first. The primary outcome was a composite of death or neurodevelopmental impairment (cognitive delay, cerebral palsy, or hearing or vision loss) at 22 to 26 months of age, corrected for prematurity.

Diagnosis of slow ventricular tachycardia by cardiac resynchronization devices utilizing a desynchronization detection algorithm.

Some cardiac resynchronization therapy (CRT) devices equipped with left ventricular (LV) sensing can develop a specific desynchronization rhythm. Contemporary BIOTRONIK devices are designed with an algorithm called "CRT pacing interrupt" exclusively designed to record the occurrence of the specific form of desynchronization. We report six patients in whom the CRT pacing interrupt function permitted the diagnosis of slow ventricular tachycardia (VT).
