Synchronous Papillary Thyroid Cancer and Colorectal Cancer in a Young Patient with a CHEK2 Mutation.

Introduction: Mutations of are usually inherited and have been implicated in breast cancers, colorectal cancers, thyroid cancers, kidney cancers, and prostate cancers. The CHEK2 gene codes for checkpoint kinase 2 protein which is an effector in the ATM-CHEK2-p53 pathway and responds to DNA double-strand breaks.

Case Presentation: We describe a unique case of a 29-year-old Canadian female who presented with synchronous papillary thyroid carcinoma and rectal adenocarcinoma who was subsequently found to have a sporadic CHEK2 (checkpoint kinase 2) mutation.

Fact vs. fiction: naloxone in the treatment of opioid-induced respiratory depression in the current era of synthetic opioids.

Opioid-induced respiratory depression (OIRD) deaths are ~80,000 a year in the US and are a major public health issue. Approximately 90% of fatal opioid-related deaths are due to synthetic opioids such as fentanyl, most of which is illicitly manufactured and distributed either on its own or as an adulterant to other drugs of abuse such as cocaine or methamphetamine. Other potent opioids such as nitazenes are also increasingly present in the illicit drug supply, and xylazine, a veterinary tranquilizer, is a prevalent additive to opioids and other drugs of abuse.

The Rothman Index predicts unplanned readmissions to intensive care associated with increased mortality and hospital length of stay: a propensity-matched cohort study.

Background: Patients with unplanned readmissions to the intensive care unit (ICU) are at high risk of preventable adverse events. The Rothman Index represents an objective real-time grading system of a patient's clinical condition and a predictive tool of clinical deterioration over time. This study was designed to test the hypothesis that the Rothman Index represents a sensitive predictor of unanticipated ICU readmissions.

Revision Surgery Risk After Open Reduction and Internal Fixation Versus Acute Total Hip Arthroplasty in Geriatric Acetabular Fractures: A Nationwide Study.

Background: The aging population has contributed to a rising incidence of acetabular fractures in older patients, yet current evidence guiding surgical treatment is limited by small sample sizes. This study used a nationwide database to investigate outcomes in older patients undergoing open reduction and internal fixation (ORIF) versus acute total hip arthroplasty (THA).

Methods: The PearlDiver database was queried for patients aged 60 years and older with an acute acetabular fracture who underwent ORIF or acute THA (2010 to 2021).

Utilizing kinematic analysis of postural instability as an objective measure to aid in distinguishing between normal pressure hydrocephalus and Parkinson's disease.

Objective: Patients with normal pressure hydrocephalus (NPH) and Parkinson's Disease (PD) can clinically appear quite similar at baseline evaluation. We sought to investigate the use of kinematic assessment of postural instability (PI) using inertial measurement units (IMUs) as a mechanism of differentiation between the two disease processes.

Methods: 20 patients with NPH, 55 patients with PD, and 56 age-matched, healthy controls underwent quantitative pull test examinations while wearing IMUs at baseline.

Placental differences between severe fetal growth restriction and hypertensive disorders of pregnancy requiring early preterm delivery: morphometric analysis of the villous tree supported by artificial intelligence.

Background: The great obstetrical syndromes of fetal growth restriction and hypertensive disorders of pregnancy can occur individually or be interrelated. Placental pathologic findings often overlap between these conditions, regardless of whether 1 or both diagnoses are present. Quantification of placental villous structures in each of these settings may identify distinct differences in developmental pathways.

Rates of Compliance in South Indian American Communities of Southern California Regarding Cancer Screening.

Background: Studies have shown lower rates of cancer screening and high mortality rates among all Asian Americans than among non-Hispanic White populations. However, most of these studies often confound diverse Asian American subgroups with limited data on cancer screening for Indian Americans, with this group being particularly interesting because of their counterintuitive socioeconomic status. For this reason, the objective of this study is to evaluate knowledge of the United States Preventive Services Task Force (USPSTF) cancer screening guidelines and compliance among South Indian Americans residing in Southern California.

Contemporary management of open extremity fractures: What you need to know.

Open extremity fractures are high-risk injuries prone to significant complications, including soft tissue loss, bone defects, infection, infected nonunion, and the necessity for limb amputation. Large-scale multicenter prospective studies from the Lower Extremity Assessment Project and the Major Extremity Trauma Research Consortium have provided novel scientific insights pertinent to the timeliness and appropriateness of specific treatment modalities aimed at improving outcomes of patients with open extremity injuries. These include the imperative for early administration of intravenous antibiotics within 3 hours of injury, preferably within 1 hour of hospital admission.
