Response: We examined medical records from 13,988 adults hospitalized with severe hyponatremia between 2008 and 2023 across 21 community hospitals in the Kaiser Permanente Northern California health system. Patients were grouped based on how quickly their sodium levels were corrected within a 24-hour period (< 8 meq/L, 8-12 meq/L, > 12 meq/L) and were followed for up to 90 days.
The primary outcome was death or serious delayed neurologic events, such as brain damage, seizures, paralysis, or altered consciousness. The results suggest that there is likely a true independent association between slow sodium correction and adverse outcomes, and that current guidelines promoting slow correction of sodium levels should be re-evaluated accordingly.

Response: AKI (Acute Kidney Injury) is a major contributor to end-stage kidney disease (ESKD).
About a third of patients with ESKD recover kidney function due to AKI. The study looked at the health outcomes of 22,922 patients from the U.S. Renal Data System from 2005 to 2014 to construct a clinical scoring system to predict kidney recovery within 90 days and 12 months after the start of dialysis for kidney failure patients due to acute kidney injury (AKI)

Response: Adding salt to foods is a behavior reflecting long-term preference to salty diets. High sodium intake is a major risk factor for chronic kidney disease.
In our previous studies, we have found that adding salt to foods at the table is related to various disorders including cardiovascular diseases, diabetes, and mortality.

Response: This was a long-term study spanning 16 years and began with a population of young adults who were medically assessed on a regular basis. It was remarkable to see just how striking the effects of coffee were in the group that had the susceptible genetic variant, what we termed “slow caffeine metabolizers” yet no effect whatsoever in those who did not were termed “fast metabolizers”.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Very little is known about the care and outcomes of patients who reach the end stages of kidney disease and do not pursue dialysis. We conducted a systematic review of longitudinal studies on patients with advanced kidney disease who forgo dialysis to determine their long-term outcomes.
We found that many patients survived several years and experienced sustained quality of life until late in the illness course. However, use of acute care services was common and there was a high degree of variability in access to supportive care services near the end of life.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: A majority of people on dialysis who completed vaccination as of September 2021 have had a decline in antibody response to levels that would render them vulnerable to infection. Antibody response immediately after vaccination and circulating antibody response is strongly associated with risk for breakthrough after the initial vaccination series.
