History of Jerry Starr Sleepout: Might you be able to help on Feb. 6?
(Editor’s note: This is Part 6 of a short 6 Part Mini-series which explains the history behind the Kenmore-Town of Tonawanda School District’s Jerry Starr SleepOut initiative which helps families in need in the Ken-Ton Community.) At the end of Part 2 it was mentioned that the next sleepout will be on Feb. 6. Any donations whatsoever of cash, food, clothes, personal care items or small furniture items will be most appreciated.
History of Jerry Starr Sleepout: E.T.C. Envisions a Vision
(Editor’s note: This is Part 4 of a short 6 Part Mini-series which explains the history behind the Kenmore-Town of Tonawanda School District’s Jerry Starr SleepOut initiative which helps families in need in the Ken-Ton Community.) As mentioned in Part 3 of this series, changes began to occur to E.T.C.’s original donor list of 5, and in 2014 and a few years beyond, E.T. C. added 3 for a total of 8. Presently we only do 3. Why?
History of Jerry Starr Sleepout: Who/What is E.T.C.?
(Editor’s note: This is Part 1 of a short 6 Part Mini-series which explains the history behind the Kenmore-Town of Tonawanda School District’s Jerry Starr SleepOut initiative which helps families in need in the Ken-Ton Community.) This short 6 Part Mini-series is nothing more than a story about people helping people, that’s all. It starts with the formation of a group which has a very simple name and which espouses a sole goal.
SuperPart: Supervised graph partitioning for record linkage
Identifying sets of items that are equivalent to one another is a problem common to many fields. Systems addressing this generally have at their core a function s(di, dj ) for computing the similarity between pairs of records di, dj . The output of s() can be interpreted as a weighted graph where edges indicate the likelihood of two records matching. Partitioning this graph into equivalence classes is non-trivial due to the presence of inconsistencies and imperfections in s().
Scalable blocking for very large databases
In the field of database deduplication, the goal is to find approximately matching records within a database. Blocking is a typical stage in this process that involves cheaply finding candidate pairs of records that are potential matches for further processing. We present here Hashed Dynamic Blocking, a new approach to blocking designed to address datasets larger than those studied in most prior work.
Oral sorbents for small, charged uremic toxins, and carbon block for regeneration of dialysate: fourth down and long
Abstract Complexities of sorbent regeneration of dialysate led me to look at other ways to use sorbents to remove uremic toxins. An oral sorbent containing cation and anion exchangers showed effective binding of potassium, phosphate, sodium, hydrogen, and ammonium (from urea) in vitro. Animal studies are ongoing. Carbon block columns can effectively bind organic and middle molecules toxins from the dialysate.
7% sodium citrate (with benzyl alcohol) as catheter lock: Dedication or obsession?
Abstract The standard heparin lock for dialysis catheters in US dialysis units is 1000 units/ml, though its use has significant limitations and problems. The alternative catheter lock of 4% sodium citrate is used in some patients, but a 7% solution would maintain catheter patency better than the 4% concentration.
Wearable and implantable artificial kidney devices for end‐stage kidney disease treatment-Current status and review
2.1 Intermittent hemodialysis Economical limitations result in repetitive high-efficacy short-duration procedures rinsing the blood from uremic toxins and quickly removing accumulated fluid load using an extracorporeal circuit, incorporating a dialyzer. Most hemodialysis types are performed intermittently, such as 4 hours/session performed 2–4 times/week. Between treatment sessions, uremic toxins, and excess fluid load re-accumulate.
ZuraGard™: Being second with a better product
Abstract In course of developing an anticoagulant and antibacterial catheter lock solution, we demonstrated that the components and alcohol formed an effective skin antiseptic. Ash Access formed a sister company to focus on development and clinical trials of this skin preparation and exchanged intellectual property for part ownership.

A lifelong quest to make home hemodialysis simple, safe, and effective: A review of outcomes of 12 major projects
Abstract In the course of over four decades, I have worked with an R&D team on 12 major R&D projects, all with the goal of making hemodialysis simple, safe, effective, and suitable for use in the home. Our team has worked within a University and in private companies and has collaborated with major healthcare drug and device companies. As a practicing nephrologist, my definition of success is when I see the device or drug we helped to develop in widespread clinical use.
