Management of common pediatric ear complaints in the emergency department.

The clinical presentation for ear complaints can often overlap with other common pediatric conditions. As such, the differential diagnosis for ear complaints is broad, warranting a thorough history and targeted physical examination. Optimizing the approach for a definitive ear examination is essential when evaluating a pediatric patient with an ear concern.

Tumor Volume Doubling Time of Less Than One Year is Associated with a Higher Risk of Death from Medullary Thyroid Cancer.

Context: Tumor volume doubling time (TVDT) is emerging as a useful tool in predicting oncologic outcomes. There is limited data on the prognostic role of TVDT in metastatic medullary thyroid cancer (MTC).

Purpose: The goal of this study was to assess the value of TVDT in predicting disease-specific survival (DSS) in patients with hereditary and sporadic MTC.

Selection on genome-wide gene expression plasticity of rice in wet and dry field environments.

Gene expression can be highly plastic in response to environmental variation. However, we know little about how expression plasticity is shaped by natural selection and evolves in wild and domesticated species. We used genotypic selection analysis to characterize selection on drought-induced plasticity of over 7,500 leaf transcripts of 118 rice accessions (genotypes) from different environmental conditions grown in a field experiment.

Association of Free Thyroxine with Progression-Free Survival in Intermediate and High Risk Differentiated Thyroid Cancer.

Context: Supraphysiologic thyroxine (T4) doses are used in intermediate and high-risk patients with differentiated thyroid cancer (IR/HR-DTC) to suppress tumor progression by thyrotropin (TSH). However, preclinical data suggest that T4 can also act as a growth stimulus for cancer, but there is no clinical evidence supporting this claim.

Objective: We analyzed the association between free T4 (FT4) and progression-free survival (PFS) in patients with IR/HR-DTC.

Paraplegic Patient with Metastatic Papillary Thyroid Cancer: A Multidisciplinary Approach to Radioactive Iodine Therapy Safety and Efficacy Strategy.

High-activity radioactive iodine (RAI) therapy for metastatic thyroid cancer (TC) requires isolation to minimize radiation exposure to third parties, thus posing challenges for patients needing hands-on care. There are limited data on the approach to high-activity RAI treatment in paraplegic patients. We report a state-of-the-art multidisciplinary approach to the management of bedbound patients, covering necessary radiation safety measures that lead to radiation exposure levels as low as reasonably achievable.

Prehospital Partial Resuscitative Endovascular Balloon Occlusion of the Aorta for Exsanguinating Subdiaphragmatic Hemorrhage.

Objective: To establish whether prehospital zone 1 (supraceliac) partial resuscitative endovascular balloon occlusion of the aorta (Z1 P-REBOA) can be achieved in the resuscitation of adult trauma patients at risk of cardiac arrest and death due to exsanguination.

Increasing Emotional Distress and Use of Health Services among Hospitality Industry Workers During and After the COVID-19 Lockdown.

Objective: To examine the emotional distress situation among hospitality industry workers and their access to and use of health care including telehealth services during the COVID-19 pandemic.

Methods: A survey was administered on the Qualtrics platform both in English and Spanish from November 18, 2020, to November 30, 2020, through the Culinary Workers Union in Nevada. A total of 1182 union members participated in the survey, of whom 892 completed the survey.

A comprehensive pediatric cardio-oncology program: a single institution approach to cardiovascular care for pediatric patients with cancer and childhood cancer survivors.

Cardiovascular complications related to cancer therapies are broad and variable in onset. These complications are the leading cause of non-cancer related morbidity and mortality in childhood cancer survivors and can also impact ongoing cancer treatment. Despite this understanding, dedicated cardio-oncology programs are lacking in pediatric cardiology.

Effect of different instrumentation techniques on students' performance and outcomes of nonsurgical root canal treatment.

Objectives: This study compared, retrospectively, the incidence of clinical errors and effects on treatment outcomes, when students were exposed to two different instrumentation techniques: a hybrid rotary technique (HYB), consisting of both hand instrumentation with hand stainless steel and Ni-Ti files plus the use of a rotary system (Vortex Blue, Dentsply Sirona), versus a full reciprocation instrumentation technique (WaveOne Gold [WOG], Dentsply Sirona).

Methods: A total of 368 endodontic cases (n = 184) in anterior and premolar teeth, completed by dental students at the University of Michigan School of Dentistry from 2013 to 2022, were used for the study. The groups were evaluated by two calibrated clinicians, observing the incidence of clinical errors: file separations, over-instrumentation, ledges and transportations.

Invasive Testing for Preoperative Localization of Parathyroid Tumors.

Context: The identification of parathyroid tumor(s) in patients with persistent/recurrent primary hyperparathyroidism (PHPT) is critical for a successful reoperative surgery. If noninvasive studies (ultrasound, computed tomography, magnetic resonance imaging, sestamibi) fail to conclusively localize the tumor, invasive procedures (arteriography and selective venous sampling) are performed.

Objective: To describe our experience with invasive studies for parathyroid tumor localization and provide follow-up data on selective arterial hypocalcemic stimulation with central venous sampling, a technique developed at our center.

Characterizing Air Medical Transport Experiences in Emergency Medicine Residency Training Programs.

Objective: Air medical transportation (AMT) of patients plays a critical role in the prehospital care of the ill patient. Despite its importance, there is no requirement in emergency medicine training programs to have direct experience or education on the topic, and data detailing current AMT experiences across programs are limited.

Methods: A survey detailing program characteristics, AMT experience characteristics, and curriculum factors relating to AMT experience was sent to all 275 credentialed emergency medicine residency training programs in the United States.

Emergency Department Resuscitative Endovascular Balloon Occlusion of the Aorta in Trauma Patients With Exsanguinating Hemorrhage: The UK-REBOA Randomized Clinical Trial.

Importance: Bleeding is the most common cause of preventable death after trauma.

Objective: To determine the effectiveness of resuscitative endovascular balloon occlusion of the aorta (REBOA) when used in the emergency department along with standard care vs standard care alone on mortality in trauma patients with exsanguinating hemorrhage.

Design, Setting, And Participants: Pragmatic, bayesian, randomized clinical trial conducted at 16 major trauma centers in the UK.

Heterogeneity of Asthma Care Among Hispanic Subgroups: Lower Utilization of Hospital-based Care among Spanish-speaking Hispanics.

Background: Studies found heterogeneity of asthma prevalence among Hispanic subgroups using survey data but addressed under-diagnosis issues due to limited access to health care and diagnosis bias.

Objectives: To examine heterogeneity by language in health care utilization for asthma among Hispanic subgroups.

Research Design: A retrospective, longitudinal cohort study of Medi-Cal claims data (2018-2019) using logistic regression to estimate the odds ratio of health care utilization for asthma.

Engaging the Poultry Industry to Vaccinate Vulnerable Populations, Arkansas, 2021-2022.

The poultry and meatpacking industry is one of the largest in Arkansas and was associated with several COVID-19 outbreaks at the start of the pandemic. Marshallese and Hispanic workers account for much of the poultry and meatpacking workforce and were disproportionately affected. The Arkansas Department of Health held worksite vaccination clinics and administered 1794 doses.

Impact of Glucocorticoids on Cardiovascular System-The Yin Yang Effect.

Glucocorticoids are not only endogenous hormones but are also administered exogenously as an anti-inflammatory and immunosuppressant for their long-term beneficial and lifesaving effects. Because of their potent anti-inflammatory property and ability to curb the cytokines, they are administered as lifesaving steroids. This property is not only made use of in the cardiovascular system but also in other major organ systems and networks.

The utility of low-iodine diet in preparation for thyroid cancer therapy with radioactive iodine-A cohort study.

A low-iodine diet (LID) of <50μ iodine/day is recommended as preparation for radioactive iodine (RAI) therapy in patients with differentiated thyroid cancer (DTC). The 24-h urinary iodine excretion (UIE) is utilized to evaluate the iodine-depleted status. The aim of this study was to test the association between UIE and progression-free survival (PFS).

Warning Labels and High-Powered Magnet Exposures.

Background And Objectives: High-powered magnets are among the most dangerous childhood foreign bodies. Consumer advocates and physicians have called for these products to be effectively banned, but manufacturers assert warning labels would sufficiently mitigate risk.

Methods: Subjects from Injuries, Morbidity, and Parental Attitudes Concerning Tiny High-powered Magnets (IMPACT of Magnets), a retrospective, multicenter study of children with high-powered magnet exposures (ie, ingestion or bodily insertion), were contacted.

Metastatic Grade 3 Neuroendocrine Tumor in Multiple Endocrine Neoplasia Type 1 Expressing Somatostatin Receptors.

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) may occur in 30% to 90% of patients with multiple endocrine neoplasia type 1 (MEN1). However, only 1% of GEP-NETs are grade 3 (G3). Given the rarity of these aggressive tumors, treatment of advanced G3 GEP-NETs in MEN1 is based on the treatment guidelines for sporadic GEP-NETs.

The feasibility study of XACT imaging for characterizing osteoporosis.

Background: Osteoporosis is a progressive bone disease that is characterized by a decrease in bone mass and the deterioration in bone microarchitecture, which might be related to age and space travel. An unmet need exists for the development of novel imaging technologies to characterize osteoporosis.

Purpose: The purpose of our study is to investigate the feasibility of X-ray-induced acoustic computed tomography (XACT) imaging for osteoporosis detection.

Post-Discharge Transitional Care Program and Patient Compliance With Follow-Up Activities.

We explore whether the frequency of post-hospital discharge transitional care calls affects patients' adherence to their discharge plans. We reviewed 1,000 call records of a post-discharge transitional care program run by a large U.S.

Multimodal profiling of lung granulomas in macaques reveals cellular correlates of tuberculosis control.

Mycobacterium tuberculosis lung infection results in a complex multicellular structure: the granuloma. In some granulomas, immune activity promotes bacterial clearance, but in others, bacteria persist and grow. We identified correlates of bacterial control in cynomolgus macaque lung granulomas by co-registering longitudinal positron emission tomography and computed tomography imaging, single-cell RNA sequencing, and measures of bacterial clearance.
