Check the guidelines

based on the American Association for the study of liver diseases  guidelines

Audit C score has 3 questions and if score is 5 or more, should prompt the full AUDIT of 10 questions.  Most questions ask about the past year alcohol habits. In a full AUDIT , any 15 or above represents high risk of alcohol dependence.

Number 3 is correct but not universal. A standard drink in US contains 14g, 10g in many EU countries and 8g in the UK. EASL advices to standardise to 10g (1 unit) but this is down to the individual countries. https://auditscreen.org/

With his age, cholesterol:HDL ratio and the BMI the QRISK score is >10% therefore statins are indicated in his case.

Abdominal US is indicated in all cases of abnormal liver blood test.  If proved to have MASLD (Fatty liver on the US) then should be screened for Hb1Ac for type 2 diabetes.

Lifestyle modification is the most important treatment in his case.

Even though doing a FibroScan is never bad practice (it is non invasive and very helpful to estimate the level of liver fibrosis) the fact is that FibroScan would be strictly indicated IF the FIb4-score was > 2 (remember the cutoff in >65 yo is 2 instead of 1.3).

Misty mesentery refers to a non-specific radiological finding characterized by increased attenuation within the mesenteric fat on computed tomography  imaging.  It mimics mistiness as localised fat stranding in the mesentery.  Many processes can lead to the appearance including infiltration by inflammatory cells, oedema, lymphatic accumulation, haemorrhage, tumour infiltration, and fibrosis.  Tipically reflects mesentery panniculitis  ( rare  benign condition characterized by chronic inflammation  of adipose tissue mainly of the small bowel mesentery) But can be the results of any inflammatory or neoplasic process. That is why it is needed to consider also vasculitis, lymphomas, inflammatory process or GI neoplasia.

Pancreatic cancer tends to have an ominous character, partly cause disease is a) advanced age, so even in resectable cases many patients are unfit for surgery and b) most cancers are borderline resecable, irresectable or metastatic. (80% of the pancreatic cancers are diagnosed in advanced stages)

Even in patient with surgical resection, the 5-year survival is quoted as 27%

A recent review showed that 5-year survival is 30% in Ia (T1 N0 M0- single 2cm or less panc mass)  dropping to 11.8% in Ib ( T2 N0 M0, this is single mass 2-4cm). When putting all the stages together, the 5 year survival is only 5%.

The best possible outcome would theorically be in an early cancer, 2cm or less (T1), found either incidentally (or if it gives symptoms very early), resectable (non conctacting vessels and not involving other anatomical structures, as well as surgically accesible)  and in a fit patient amenable for surgery.

Andexanet is factor Xa inhibitor which is approved to reverse Rivaroxaban and Apixaban. However, it has not being proved to be efficacious against Edoxaban. Dabigatran is  a direct thrombin (factor IIa) inhibitor, not a Xa inhibitor.

The majority of pancreatic cancers are due to spontaneous mutations in a complex combination of usually several mutations ((KRAS) mutations are common in 90% of pancreatic cancers, but in combination with different other mutations, DNA damage and usually other risk factors.

There is however a very important percentage (5%-10%) of new PC which associate familial pancreatic cancer (Defined by two first-degree-relatives with pancreatic cancer), There are indeed genes involved such as BRCA2 gene  mutations  ( 3.5-fold increased risk of pancreatic cancer ).  Other inherited mutations in the STK11 gene cause the Peutz-Jeghers syndrome, and individuals with Peutz-Jeghers have a 130-fold increased risk of pancreatic cancer

To put in context,

One degree relative with PC  makes relative having an 80% increased risk of developing pancreatic adenocarcinoma (this is RR: 1.8)

individuals with 2 degree relatives with PC have a nine fold risk , and this rises to thirty-two times greater risk if three or more first degree relatives have been previously diagnosed

Difficult question.  This response is based on Waterfall trial that compared moderate resucitation (1.5ml per Kg) vs aggressive (3ml per Kg) and showed no difference in worsening pancreatitis  but a tendency of fluid overload in the aggresive group (20.5% vs. 6.3%).

Ringer lactate or Hartmanns have been proved to have benefit ovver saline due to an anti-inflammatory effect which was attributed to the properties of lactate and to have a higher pH that can help counteract acidosis.

This indeed is a subject of debate. American guidelines still mentions that most patients with acute pancreatitis & hypovolaemia could have a deficit of 3-4 L to replace in 24h (Like it is our patient with vomiting and  mild hypotension and tachycardia) . If patient has no evidence of hypovolemia, an initial resuscitation rate of no more than 1.5 mL/kg of body weight per hour should be administered. However, in patients with hypovolemia, clinicians should administer a bolus of 10 mL/kg which in this case is 750ml per hour (1500ml in 2 hours)

So, the answer is  Goal-directed rehydration with Ringer’s lactate solution (or Hartmann’s).  In this case of Hypovolemia, our first step should be resucitate until volume is stable (normal BP, HR and clinical status) looking closely to avoid overfluid, and once patient is stable, keep her on 1.5ml per Kg per 24 h with clinical re-checking every few hours to ensure she is not hyper or overhydrated.
