Purpose Of Review:
In people living with kidney disease (KD) Fatigue is a whole-body tiredness that is not related to activity or exertion. Often self-reported, fatigue is a common and highly burdensome symptom, yet poorly defined and understood. While its mechanisms are complex, many fatigue-related factors may be altered by exercise and physical activity intervention. Thus, this review aims to review the latest research on exercise in reducing fatigue in people living with KD.
Recent Findings:
The benefits of exercise in KD are well known, yet recent data from clinical trials on fatigue are scarce. Favourable effects on fatigue were found through a myriad of physical activity and exercise-based interventions, including using exercise-based video games, exercise during dialysis, nurse-led exercise programs, and home-based exercise delivered by a novel digital health intervention. Yet, whilst the handful of recent trials show positive efficacy on fatigue across the spectrum of KD, contemporary exercise-based research was impacted critically by COVID-19, and the field is limited by underpowered trials and heterogeneity of assessment tools.
Summary:
Fatigue remains, at best, a secondary outcome measure in trials despite it being the most commonly reported symptom in KD. Given its importance to the people it impacts most, better quality evidence is needed to fully understand and optimize the impact of exercise in this group.

01:11Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
01:27Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
