Recycling. Using used paper for my lab report drawings (prof doesn’t mind). I don’t get why they keep making us draw the stuff under the microscope when cameras exist??? I’m drawing Plasmodium spp. in RBCs. 

 Anyhow, my thesis partner and I passed our Final Defense yesterday (YASSS). Now on to writing - again. :|

Hey, I'm a transmasculine nonbinary person and I've been considering T for a very long time. I want to look primarily masculine, but I'm scared that acne/hair loss will prevent my self esteem from getting at all better. It doesn't help that I'll be moving next year to attend college, and if I'm going to start T I want to start it now so I can have a bit of a smoother fresh start. I don't want to make rushed desicions, but the idea of starting at college still pre-everything sounds terrible

An important part of starting hormones is the acknowledgement and acceptance of all of the potential changes and outcomes that come with it. For testosterone that includes potentially less desirable effects such as hair loss, acne, increased body hair, cardiovascular changes (increased RBC, increased cholesterol), or stronger body odor. It’s not an easy process, especially when you’re at the beginning and facing the daunting reality of not knowing how your body will be effected, but it’s vital to do that mental work and learn to accept whatever happens before beginning. You don’t have to enjoy the changes but you do need to be able to say “I don’t necessarily want this but I will accept if it happens”. It helps to remember that some of the effects (such as acne) are largely temporary while others (such as hair loss) are more permanent. Keep in mind that there are also treatments available over the counter or through your doctor that can help lessen how severe they are. Though you don’t have control over what changes happen you do have control over how you want to address them if/when they do and to what degree they’re going to effect you long-term. An important question to ask yourself here is if the potential for unwanted effects outweigh the ways in which testosterone would improve your life long-term.

Autoimmune Hemolytic Anemia (AIHA) MNEMONICS

AIHA

  • Caused by autoantibodies that react with RBCs at temperatures ≥ 37° C (warm agglutinin disease) or < 37° C  (cold agglutinin disease)
  • Extravascular hemolysis: occurs in the spleen (this is why you don’t see fragmented RBC in the smear)
  • Coombs (+)

Warm Agglutinin Disease:

Causes Mnemonic

  • L ymphoma
  • S ystemic Lupus erythematosus (SLE)
  • C LL
  • D rugs: penicillin, phenytoin, rifampin, alpha-methyldopa.

Tx

  1. Best initial tx: Prednisone
  2. Severe, Acute hemolysis & no response to Prednisone: IVIG
  3. Recurrent episodes: splenectomy
  4. No control of hemolysis after splenectomy: Rituximab, Azathioprine, Cyclophosphamide or Cyclosporine.

Cold Agglutinin Disease:

Causes Mnemonic: MEW

Numbness or mottling of colder parts of the body: nose, ears, toes, fingers

Tx

  1. Warm up
  2. Rituximab
  3. Sometimes plasmapheresis
  4. Stop Ab production: Cyclophosphamide, Cyclosporine
  5. Steroids, splenectomy DO NOT WORK here

Jaundice is a yellow discoloration of the skin and mucous membranes caused by an excess accumulation of bilirubin in the blood. Bilirubin (a tetrapyrrole) is a product of red blood cell (RBC) breakdown. Jaundice becomes visible when the bilirubin level is approximately 2 to 3 mg/dL.

The three main types of jaundice are prehepatic, hepatic, and posthepatic:

Prehepatic (hemolytic) jaundice occurs when RBC lysis exceeds the liver’s capacity to conjugate bilirubin. Causes include transfusion reactions, sickle cell anemia, thalassemia, and autoimmune disease. Large amounts of unconjugated bilirubin accumulate in the blood.

Hepatic jaundice results from hepatocyte dysfunction which limits the uptake and conjugation of bilirubin. This may occur due to hepatitis, cancer, cirrhosis, congenital disorders, and drugs. There is a rise in the levels of conjugated and unconjugated bilirubin in the blood.

Posthepatic (obstructive) jaundice occurs when gallstones, inflammation, scar tissue, or tumors block the flow of bile into the intestines. Water-soluble conjugated bilirubin accumulates in the blood.

Dividend stocks aren't as great as they used to be

The glamour of dividend stocks has lessened, says RBC Capital, as the premium investors earn from them over the benchmark Treasury rate has narrowed.

“The average dividend spread in our coverage is 1.9% currently," noted an analyst team led by Nik Modi,  "compared to 2.1% in the past 5 and 10 years.”

Narrower spreads were caused by fluctuations in the 10-year Treasury rate and changes in dividend policies, the team said.

“Although average dividend yields did not change much, the spreads vs 10Y T-bond are narrower today vs the 10-year average, but slightly wider than the 5-year average,” they added.

Meanwhile, some peculiar changes have come about in the consumer staples sector.

First, while dividend yield measured for the consumer staples index remains constant at 2.6%, spreads over the Treasury rate has changed from negative to positive.

Secondly, tobacco stocks no longer earn the highest dividend yield among consumer staples.

In fact, the team noted, “at present, KO (Coca Cola) has a higher dividend than MO (Altria Group). This compares to MO carrying a dividend yield that has historically been 200 bps-plus higher than KO.” This could be due to investor concerns over Coca Cola’s core business, combined with investor excitement over consolidation in the tobacco industry, they said.

Moya Moya Vessels

- occurs with sickle cell disease
- Hypoplasia or stenosis in bilateral distal ICAs (Internal Carotid Arteries)
- abnormally dilated collaterals
- cause hemorrhage or ischemia

Explanation: in sickle cell disease, the shape of the RBCs cause damage to blood vessels, especially at branch points. This can occur with the major arteries of the brain (internal carotids). So the body makes many smaller collateral vessels to bypass damage. These new vessels are weaker, smaller, and fragile. They provide insufficient blood supply to brain and may burst causing hemorrhage (bleeding) or ischemia (lack of blood supply).
