Objective: To evaluate the possibility of fetal compensatory renal hypertrophy with a unilateral functioning kidney.
Methods: A nomogram of renal length was established from 254 normal fetuses. Renal length was also obtained in 14 fetuses with unilateral renal agenesis and 22 fetuses with a unilateral multicystic kidney.
Results: Compensatory renal hypertrophy, defined as a renal length > 95th percentile for gestational age, occurred in 16 of 36 cases (44.4%).
Conclusions: Compensatory renal hypertrophy is detectable in utero and may occur as early as 22 weeks' gestation.

Clinical ischemia-reperfusion injury: Driven by reductive rather than oxidative stress? A narrative review.

Ischemia-reperfusion (IR) injury remains a major contributor to organ dysfunction following transient ischemic insults. Although numerous interventions have been found effective to reduce IR injury in preclinical models, none of these therapies have been successfully translated to the clinical setting. In the context of the persistent translational gap, we systematically investigated the mechanisms implicated in IR injury using kidney donation and transplantation as a clinical model of IR.

We herein report a 56-year-old man with severe hypocalcemia during ruxolitinib therapy for myelofibrosis transitioning from JAK2 mutation-positive polycythemia vera. Blood transfusions were administered every one to two weeks for ruxolitinib-induced anemia. Blood tests revealed hypocalcemia with low TRACP-5b, 25-hydroxyvitamin D (25 (OH) D), and 1,25-dihydroxyvitamin D (1,25 (OH) D) levels within the lower reference range.

With over 14 million people living above 3,500 m, the study of acclimatization and adaptation to high altitude in human populations is of increasing importance, where exposure to high altitude (HA) imposes a blood oxygenation and acid-base challenge. A sustained and augmented hypoxic ventilatory response protects oxygenation through ventilatory acclimatization, but elicits hypocapnia and respiratory alkalosis. A subsequent renally mediated compensatory metabolic acidosis corrects pH toward baseline values, with a high degree of interindividual variability.

Glomerular endothelial cells (GECs) are pivotal in developing glomerular sclerosis disorders. The advancement of focal segmental glomerulosclerosis (FSGS) is intimately tied to disruptions in lipid metabolism. Sphingosine-1-phosphate (S1P), a molecule transported by high-density lipoproteins (HDL), exhibits protective effects on vascular endothelial cells by upregulating phosphorylated endothelial nitric oxide synthase (p-eNOS) and enhancing nitric oxide (NO) production.

Diuretic drugs act on electrolyte transporters in the kidney to induce diuresis and are often used in chronic kidney disease (CKD), given that nephron loss creates a deficit in the ability to excrete dietary sodium, which promotes an increase in plasma volume. This rise in plasma volume is exacerbated by CKD-induced systemic and intra-renal activation of the renin-angiotensin-aldosterone-system, which further limits urinary sodium excretion. In the absence of a compensatory decrease in systemic vascular resistance, increases in plasma volume induced by sodium retention can manifest as a rise in systemic arterial blood pressure.
