Advantages:
- Lower infection rate then central lines
- Used in the outpatient setting
- Can be used for several weeks to months
- Duration of PICC lines may be from 4 weeks to 6 months
(although they have been known to be functional for more than 300 days)

Did you know that pregnant people with #antiphospholipidsyndrome (APS) have an increased risk of adverse maternal & fetal outcomes? (1/4)
APS is characterized by #thrombosis and/or obstetric morbidity in the presence of #antiphospholipid antibodies. For pregnant people, this means increased likelihood of severe #preeclampsia, preterm birth, & #neonatalmortality. (2/4)
Studies show that complement activity plays a key role in aPL-mediated #thrombosis & obstetric complications. And fortunately, complement inhibitors, like #eculizumab, offer promise of improved outcomes for pregnant people living with APS. (3/4)

In the early 1940s, folic acid was isolated and found to cure some patients with megaloblastic anemia, not responding to vitamin B 12.
Also, patients with acute leukemia were treated with folic acid or folate conjugates (polyglutamated forms of folic acid)
👉proved ineffective:(

👉proved ineffective:(
The subsequent demonstration by Heinle and Welch that a diet-induced deficiency of folic acid caused a decrease in the leukemia cell count, stimulated efforts, primarily by the Lederle group, to synthesize analogs of folic acid.

My 3 year old daughter Lila was recently diagnosed with a VERY rare and aggressive type of #leukemia.
👉 It’s potentially treatment resistant… AND
👉 Requires a bone marrow transplant.

First, some background:
👉 A month ago, Lila was diagnosed with “acute undifferentiated leukemia” (AUL) by her docs at @ChildrensLA
👉 Last week, we found an unrelated marrow donor who’s a perfect “10/10” match (thx to @BeTheMatch ) and they have agreed to donate. 😭

👉 But just yesterday, we learned Lila’s first cycle of chemo failed. 🥺
Before Lila can get the transplant, we have to get her into remission first.

1/ Do you know who this man is? 🧵
He’s Fredrick W Mott, an English 🏴surgeon who identified cells with multiple spherical inclusions packed in their cytoplasm in the brains of monkeys with trypanosomiasis.

2/ In the early 1900s, he identified them as plasma cells in inflammation and called them morular cells (Latin morus=mulberry). He was later given the honour of having these cells named after him.

3/ It was actually William Russell, a Scottish 🏴physician before Mott, who recognised these inclusions contain immunoglobulin. The individual cytoplasmic inclusions (Russell body) are hence named after him.

I’ve never posted a @tiktok_us link before, but this is a rare opportunity to observe one of the most poorly understood disorders in #hematology: Gardner-Diamond syndrome. This young woman's skin lesions first appear about 40 seconds in./1 #MedTwitter tiktok.com/@nancy.xoxx/vi…
The syndrome was described by Drs. Frank Gardner (1919-2013) and Louis K. Diamond (1902-1999) in Boston in 1955, in @BloodJournal. They reported 4 cases, all women, who had a peculiar form of bruising on face or extremities but had no other bleeding & normal coagulation tests./2
The key finding in Gardner-Diamond syndrome: unexplained painful bruises, most commonly on extremities or face, often during times of stress. The pathophysiology is unclear, as described below. Many patients have been dismissed by physicians as having a fictitious disorder./3

The risk of reactivation depends on CMV sero status:
D-/R+ > D+/R+ > D+/ R- > D- / R -
Other risk factors are:
1️⃣T cell depletion
2️⃣HaploSCT
3️⃣UCB SCT
4️⃣GVHD requiring steroids
So why not give prophylaxis to these "high-risk" patients ??
