Albumin - NOT a marker of malnutrition

 Albumin

- Half life 20 days


- Strong Negative acute phase reactant


- Causes of hypoalbuminemia
   a) Inflammation - reduced production by liver / increased catabolism
   b) Increased losses - Urine / Gut


- Note: Albumin is NOT a marker of nutritional status in general


- low albumin is a/w poor outcomes in general for above reasons


A systematic review assessed the role of albumin and prealbumin in otherwise healthy subjects who were severely nutrient- deprived due to poor access to food or unwillingness to eat, mostly due to anorexia nervosa [40]. The study showed that serum albumin and prealbumin levels were maintained even in the presence of distinct weight loss, and they were lowered only during extreme starvation (BMI < 11 kg/m2). 


Serum Albumin and Prealbumin in Calorically Restricted, Nondiseased Individuals: A&nbsp;Systematic Review | Elsevier Enhanced Reader - is my fav paper really debunking the age-old myth of albumin and nutrition, once and for all.

Pancreatic Cyst

Image
 MCN - (Mother cyst) >95% in pre-menopausal women Mostly in body and tail of pancreas Thick-walled cyst, lined by Ovarian type stroma. Cyst contains mucinous / hemorrhagic material. Does not communicate with PD (unlike IPMN) 10-20% have in-dwelling cancer One review found - no dysplasia in cysts <3 cm in size LN mets is rare. Distal pancreatectomy usually suffices.  Doesnt result in metachronous lesions. Surveillance isnt really necessary SCA - (Grandmother cyst) 75% of SCAs seen in post-menopausal women Can be anywhere in pancreas Honeycombing, with tiny cysts containing clear fluid distributed around central scarring. Central scarring may bear calcification in 30% cases Microcystic SCAs can undergo degeneration and become macrocystic variants zero risk of malignancy, but they can continue to grow and cause obstructive symptoms SPN - (daughter lesion) - Solid Pseudopapillary Neoplasm 90% of lesion occur in young women, in teens / twenties Anywhere  in pancreas Sol...

Pancreatic stent does not provided added advantage over rectal NSAID for prevention of post-ERCP pancreatitis: First ever RCT

Image
 DOI:  10.1097/MPA.0000000000002090 Consecutive 321 patients with native papilla,  were randomly assigned to Pancreatic stent, 50mg rectal diclofenac or stent + diclofenac at a single centre in Japan from 2014 to 2019. Pancreaitc injection performed in nearly half of all patients! 75% of all patients were considered high risk (either F<40, difficult cannulation, pancreatic cannulation, pancreatic injection, pre-cut, pancreatic sphincteortomy, balloon sphincteroplasty, IDUS, choledochoscopy)  Procedure time was >30 mins in half of all patients. 5 patients in total developed pancreatitis (all mild), with no difference in any of the 3 sub-groups.
