Effects Of Hypobaric Hypoxia During Intermittent Cycling Bouts On Markers Of Acute Kidney Injury, Jacob D. Dawes, Alyssa R. Bailly, Jonathan W. Specht, Christopher B. Hart, Mateo Griego, Marissa Ramirez, Kaia G. Allen, Alexander Smaragdas, Fabiano T. Amorim

International Journal of Exercise Science: Conference Proceedings

Many individuals travel to high altitudes for recreational or occupational purposes. Hypobaric hypoxia (HH) at altitude decreases arterial oxygen saturation (SaO₂), reduces oxygen delivery to tissues, and can adversely affect organ function. Exercise, independent of HH, significantly decreases renal blood flow (RBF). Therefore, performing exercise in HH may further impair oxygen delivery and place additional strain on the kidneys. While the impact of chronic HH on kidneys has been documented, there is limited research on the risk of acute kidney injury (AKI) under these conditions. PURPOSE: To investigate the effects of acute HH exposure during intermittent exercise …

Effect Of Previous Night Alcohol On Thermoregulatory And Physiological Strain During Prolonged Physical Work In The Heat, Marissa Ramirez, Jonathan W. Specht, Flavio De Castro Magalhaes, Fabiano Amorim, Whitley C. Atkins

International Journal of Exercise Science: Conference Proceedings

Many occupational workers engage in strenuous physical work in hot environments for prolonged periods, placing them at risk of heat-related illness due to increasing physiological strain identified by increasing core temperature (Tcore) and heart rate (HR). Lifestyle behaviors, such as smoking, caffeine and alcohol consumption, and sleep deprivation, may further exacerbate heat strain and increase susceptibility to heat-related illness. Notably, alcohol consumption the night before work, and the subsequent hangover, may amplify physiological strain by impairing heat dissipation. However, no previous studies have evaluated the impact of alcohol hangover on heat strain during physical work in the heat. PURPOSE: …

Sex-Specific Changes In Pbmc Mitochondrial Respiration Following Acute Exercise, Ryan R. Moon

International Journal of Exercise Science: Conference Proceedings

Exercise-trained individuals exhibit greater immune system function, which may be attributed in part to enhanced peripheral blood mononuclear cell (PBMC) function. Exercise training is a potent stimulator of mitochondrial adaptation, which may help explain improvements in immunity. However, the mechanisms by which exercise acutely modulates PBMCs to promote beneficial adaptations remain unclear. Purpose: The purpose of this study was to test the hypothesis that a single bout of aerobic exercise modulates PBMC mitochondrial function. Methods: Twenty-eight healthy young adults (13 females, 15 males; age 21.84 ± 2.78 years) completed a graded exercise test (VO₂max: 41.4 ± 7.64 ml O₂·kg⁻¹·min⁻¹) followed …

Real-Time Hemodynamic Deterioration Following Polymorphic Ventricular Tachycardia In A Patient With Preexisting Aicd Implanted With Lvad, Dhruvil Patel, Maya Guglin, Deepa Iyer, Chonyang Albert, Jagpreet Grewal, Kenneth Dulnuan

The VAD Journal

Ventricular arrhythmias (VAs) are common in patients with a left ventricular assist device (LVAD), but the literature remains inconclusive regarding the benefits of an automatic implantable cardioverter-defibrillator (AICD) in this population, especially in those with a preexisting device before LVAD implantation. Here, we report the acute hemodynamic consequences of polymorphic ventricular tachycardia in a patient with a preexisting biventricular AICD who was implanted with an LVAD (HeartMate 3). This case underscores the importance of considering AICD placement on a case-by-case basis and highlights the need for a well-designed study to establish its benefit in this population.

Clinicopathological Features Of Colorectal Cancer In Young Patients In Comparison With Older Patients, Bahaa Al-Neama, Wasam Al-Asadi

Iraqi National Journal of Medicine

Background:  Colorectal cancer (CRC) has traditionally been considered a disease of older adults; however, recent evidence shows an increasing incidence among younger patients. Understanding the differences in clinicopathological features between young and older individuals is essential for improving early diagnosis, treatment strategies, and outcomes. Aim: The primary objective of this study is to compare the demographic profiles and clinicopathological characteristics of younger patients (aged <40 years) with those of older patients (aged ≥40 years) diagnosed with colorectal cancer. Methods: Eighty-five consecutive patients admitted to our hospital were prospectively followed for their entire hospital stay or up to 7 days, whichever came first. Each patient's blood glucose measurement was recorded according to ward protocol. Indices included total blood glucose per ward, per patient-day, or patient stay, and percentage blood glucose levels per predefined cut points to assess the incidence of hypo-, eu-, and hyperglycemia. The trial registration number at Clinicaltrials.org is NCT04800861. Results: Total data consisted of 645 blood glucose tests from 85 patients and 284 patient-day results, with an average of 2.27 tests per patient-day and 7.59 measurements per patient stay. The percentage of blood glucose in the range (80–180 mg/dL) varied by model, with patient-day showing the highest results at 48.24%, while the percentage of patients with hypoglycemia (blood glucose <60 mg/dL) was highest per patient stay at 1.18%. Conclusions: Younger colorectal cancer patients in this study presented more frequently with rectal tumors, poor differentiation, and advanced disease stages. Despite similar symptom profiles, delayed diagnosis may contribute to worse pathological features. These findings support the need for greater awareness and consideration of earlier screening in younger populations.
