Article Synopsis
  • The study examines the rising rates of early onset colorectal cancer (EOCRC) among African American patients, highlighting significant differences between EOCRC (<45 years) and late-onset colorectal cancer (LOCRC) (>45 years) in terms of demographics and clinical presentation.
  • It found that EOCRC cases increased from just over 6% to over 13% of total CRC cases since 2010, with a higher family history of CRC and different symptom profiles, such as more abdominal pain and changes in bowel habits.
  • The study also noted that EOCRC patients had a higher rate of metastasis at diagnosis and took longer to undergo surgery compared to LOCRC patients.

Introduction: The evolving landscape of healthcare information dissemination has been dramatically influenced by the rise of artificial intelligence (AI) driven chatbots, providing patients with accessible and interactive platforms to obtain knowledge about medical procedures and conditions. Among the various surgical interventions in urology, inflatable penile prosthesis (IPP) is a common treatment for men with erectile dysfunction. As patients increasingly seek comprehensive resources to understand what this procedure entails, AI-based chat technologies, such as ChatGPT, have become more prominent.

Background And Aim: Identifying clinical characteristics and outcomes of different ethnicities in the US may inform treatment for hospitalized COVID-19 patients. Aim of this study is to identify predictors of mortality among US races/ethnicities.

Design Setting And Participants: We retrospectively analyzed de-identified data from 9,873 COVID-19 patients who were hospitalized at 15 US hospital centers in 11 states (March 2020-November 2020).

Background: Coronavirus disease 2019 (COVID-19) manifest differently depending on patients' background and pre-existing conditions. It remains unclear how African Americans with cancer have been affected in comparison to those without. In this study, we aim to identify demographic, clinical, and laboratory markers associated with mortality in COVID-19 patients with cancer.

Asymptomatic dengue virus (DENV) infections have important public health implications but are challenging to identify. We performed a cross-sectional study of reverse transcription quantitative polymerase chain reaction on pooled sera of asymptomatic individuals from the south coast of Kenya at two time periods to identify cases of asymptomatic viremia. Among 2,460 samples tested in pools of 9 or 10, we found only one positive case (0.

Introduction: Penile fracture is traditionally considered a surgical emergency warranting immediate repair with the goal to maximize long-term erectile function and minimize penile curvature. Nonetheless, consensus on the optimal timing for penile fracture repair remains to be elucidated and is the subject of continued research efforts.

Objectives: This review aims to summarize the contemporary literature pertaining to optimal timing of penile fracture repair and associated outcomes.

Background: Long-COVID is a condition post SARS-CoV-2 infection with persistent or recurring symptoms affecting multiple organs, and may involve viral persistence, changes to the microbiome, coagulopathies, and alterations to neuro-immune interactions. These factors can disrupt the Gut-Brain Axis, which is a complex system involving bidirectional communication between the central nervous system and the gastrointestinal (GI) system. As a result of these disruptions, individuals with long-COVID may develop post-infectious functional GI disorders, which can cause a range of symptoms affecting the digestive system.

Background And Aim: Type 2 diabetes mellitus (DM) is a common comorbidity in the minority population and is associated with poor outcomes in COVID-19 patients. We hypothesized that COVID-19 patients with pre-existing diabetes mellitus are prone to fatal outcomes compared to non-diabetic patients. We aimed to illustrate the characteristics and outcomes and identify the risk factors for in-hospital mortality of COVID-19 patients with DM.

Background: Coronavirus disease 2019 (COVID-19) and associated outcomes manifest differently depending on patients' background and pre-existing conditions. It remains unclear how African Americans with and without cancer have been affected.

Aim: To determine epidemiological, clinical comorbidities, and laboratory test results to identify markers associated with mortality in COVID-19 cancer patients.
