Welcome to the NephMadness PodCrawlThe idea behind a podcrawl is for a variety of podcasts to coordinate on timing and topic to push a theme and get each other’s listeners to explore all of the podcasts. One of the first goals behind NephMadness was to build a community and in the early years of Twitter, NephMadness was central to the formation of #NephTwitter and defining the ethos that makes our online community kind, intelligent, vibrant, and interesting. The NephMadness Podcrawl hopes to inspire and grow the nephrology podcast community in the same way. For 2023, our second year,  the PodCrawl has assembled the Avengers of Medical Pods!Go to NephMadness.com/podcrawl for more information and links to all of the podcasts!The Curbsiders gets the skinny on mineralcorticoid receptor antagonistsCore IM will be covering Kidney Transplant in their classic Five Pearl formatThe CardioNerds will be covering the effect of Heart Failure Devices on Kidney HealthFreely Filtered will try to understand thrombotic microangiopathyISN Global Kidney Care goes deep on IgA nephropathyThe Cribsiders look at transitions, first the Peditrics to Adult nephrology transition and then from living to death with palliative nephrology Fellow on Call will be covering OnconephrologyAnd finally, The Nephron Segment looks at Transgender Health and CKD

Show Notes:2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure says:Restricting dietary sodium is a common nonpharmacological treatment for patients with HF symptomatic with congestion, but specific recommendations have been based on low-quality evidence. Concerns about the quality of data regarding clinical benefits or harm of sodium restriction in patients with HF include the lack of current pharmacological therapy, small samples without sufficient racial and ethnic diversity, questions about the correct threshold for clinical benefit, uncertainty about which subgroups benefit most from sodium restriction, and serious questions about the validity of several RCTs in this area. However, there are promising pilot trials of sodium restriction in patients with HF. The AHA currently recommends a reduction of sodium intake to <2300 mg/d for general cardiovascular health promotion; however, there are no trials to support this level of restriction in patients with HF. Sodium restriction can result in poor dietary quality with inadequate macronutrient and micronutrient intake. Nutritional inadequacies have been associated with clinical instability, but routine supplementation of oral iron, thiamine, zinc, vitamin D, or multivitamins has not proven beneficial. The DASH diet is rich in antioxidants and potassium, can achieve sodium restriction without compromising nutritional adequacy when accompanied by dietary counseling, and may be associated with reduced hospitalizations for HF.This is 2a Class of Recommendation (moderate strength) with a C-LoD level of evidence (Limited data).Study acronym: the Study Of Dietary Intervention Under 100 Milimoles in Heart Failure. 100 mmol of sodium is 2300 mgMeta analysis of high versus low sodium diet pulled from Heart due to duplicated and missing data.

A Systematic Review It is commonly stated and assumed that mortality from acute respiratory distress syndrome (ARDS) is decreasing.We found that mortality from ARDS has not decreased substantially since the publication of a consensus definition in 1994. Based on our findings, a baseline mortality risk from ARDS of 40 to 45% for observational studies and 35 to 40% for randomized control trials should be expected. These results highlight the need for future effective therapeutic interventions for this highly lethal syndrome.https://www.atsjournals.org/doi/full/10.1164/rccm.200805-722oc From Up To Date:Numerous studies suggest that survival has improved over time [2,9,10,11]. As an example, an observational study of 2451 patients who had enrolled in ARDSNet randomized trials found a fall in mortality from 35 to 26 percent between 1996 and 2005 [10]. To the extent that mortality may be decreasing with time, several issues should be considered:● It is not known if mortality has decreased among patients who received their care outside of a specialized center or a clinical trial.● The improved mortality may be attributable to patients who have ARDS related to risk factors other than sepsis, such as trauma [9].● To the extent that mortality has decreased, the reasons are uncertain. Likely causes include better supportive care and improved ventilatory strategies, such as low tidal volume ventilation [10,12,13]Early Goal-Directed Therapy in the Treatment of Severe Sepsis and Septic Shock by Emanuel Rivers https://www.nejm.org/doi/full/10.1056/nejmoa010307 Early Goal Directed Therapy from NephMadness 2015 https://ajkdblog.org/2015/03/01/nephmadness-2015-critical-care-nephrology-region/#Early Counter point by NSMC graduate Kamran Boka https://ajkdblog.org/2015/03/18/nephmadness-2015-process-arise-promise-and-the-promise-of-early-goal-directed-therapy/ Furosemide stress test https://jasn.asnjournals.org/content/26/8/2023 EM Crit looks at the furosemide stress test: https://emcrit.org/pulmcrit/furosemide-stress-test/ ASN Kidney Week Biomarker debate between Faubel and Koyner. https://www.asn-online.org/education/kidneyweek/2020/program-session-details.aspx?sessId=371699&sessPar=371678 NAD therapy Samir Parikh Don Seldin Young Investigator Award winner 2019.Sarah Faubel’s Dream RCT https://ukidney.com/nephrology-resources/dream-rct-initiative/dream-rct-entries/item/nephrologist-driven-rrt-usual-late-or-early-start-for-acute-kidney-injury Perry Wilson’s DreamRCT https://www.medpagetoday.com/Nephrology/DreamRCT/53876 Steve Coca on “Permissive AKI” with treatment of heart failure https://www.kidney-international.org/article/S0085-2538(19)30708-2/pdf Edward Clark on HIRRT: Mechanisms for hemodynamic instability related to renal replacement therapy: a narrative review https://pubmed.ncbi.nlm.nih.gov/31407042/ Cytokine adsorption in patients with severe COVID-19 pneumonia requiring extracorporeal membrane oxygenation (CYCOV): a single centre, open-label, randomised, controlled trial https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(21)00177-6/fulltext The Handbook of Critical Care Nephrology Amazon | Target (actually not available 😩)Sophia and Sarah Tweetorial on her Lung metabolomics in AKI study: https://twitter.com/sophia_kidney/status/1390394006366994432 AKIKI NephJC coverage | NEJM manuscript

Loeb’s Laws of Medicine or Loeb’s Rules of TherapeuticsRobert Frederick Loeb (March 14, 1895-October 21, 1973) was a famous American Physician who provided some very simple common sense approach to treating patients know as:1. If what you are doing is doing good, keep doing it.2. If what you are doing is not doing good, stop doing it.3. If you do not know what to do, do nothing.4. Never make the treatment worse than the disease.The last ‘law’ in present times is often replaced with:“If at all possible, keep your patient out of the operating room.”Or“Above all, never let a surgeon get your patient.”This is a decent reference for this: https://www.ncbi.nlm.nih.gov/books/NBK13258/Dr. Glaucomflecken gives some tips for attending trying to go back to the ICU: https://twitter.com/DGlaucomflecken/status/1238954558140772354?s=20Francis Deng and going back to become an internist: https://twitter.com/francisdeng/status/1245475268158009349?s=20JCI article on using convalescent serum for treating disease: https://www.jci.org/articles/view/138003Human trial of convalescent serum from JAMA: https://jamanetwork.com/journals/jama/fullarticle/2763983 It works!
