Objectives: Chronic pancreatitis is a debilitating and progressive inflammatory disease with an altered quality of life due to severe abdominal pain. Pancreaticoduodenectomy is a surgical option for patients with bulky disease involving the head of the pancreas, especially when this disease has progressed to stricture of the bile duct, duodenum, or both. A long term issue associated with this procedure is stricture of the pancreatic anastomosis.

Article Synopsis
  • Unpredictable reactions to sedatives and analgesics in critically ill patients on mechanical ventilation may stem from genetic differences.
  • The study aimed to explore the relationship between pharmacogenomic variations and sedation outcomes, while also assessing ICU patients' views on pharmacogenomic testing.
  • The researchers found that while participants showed a median of 2 altered pharmacogenomic phenotypes, there were no significant links between these genetic variations and sedation effectiveness; however, ICU patients generally had positive attitudes towards pharmacogenomic testing.

Objectives: Clinical management of traumatic brain injury (TBI) focuses on preventing secondary injury from cerebral edema and ongoing anoxic injury. Consensus guidelines recommend maintaining systolic blood pressure (SBP) ≥ 110 mmHg. A recent prehospital study suggested lowest adjusted mortality from 130 mmHg to 180 mmHg, suggesting the ideal pressure may be higher.

Whole-organ pancreas, pancreatic-kidney and islet transplantation are surgical therapeutic options for the treatment of type 1 diabetes. They can enable effective glycemic control, improve quality of life and delay/reduce the secondary complications of type 1 diabetes mellitus. Radiologists are integral members of the multidisciplinary transplantation team involved in these procedures, with multimodality imaging serving as the mainstay for early recognition and management of transplant related complications.

Background: Total pancreatectomy with islet autotransplant (TPIAT) can improve quality of life for individuals with pancreatitis but creates health risks including diabetes, exocrine insufficiency, altered intestinal anatomy and function, and asplenia.

Methods: We studied survival and causes of death for 693 patients who underwent TPIAT between 2001 and 2020, using the National Death Index with medical records to ascertain survival after TPIAT, causes of mortality, and risk factors for death. We used Kaplan Meier curves to examine overall survival, and Cox regression and competing-risks methods to determine pre-TPIAT factors associated with all-cause and cause-specific post-TPIAT mortality.

The instant blood-mediated inflammatory response (IBMIR) causes islet loss and compromises diabetes outcomes after total pancreatectomy with islet autotransplant (TPIAT). We previously reported a possible benefit of etanercept in maintaining insulin secretion 3 months post-TPIAT. Here, we report 2-year diabetes outcomes and peri-operative inflammatory profiles from a randomized trial of etanercept and alpha-1 antitrypsin (A1AT) in TPIAT.

Background: Natural killer (NK) cells are dysfunctional in chronic human immunodeficiency virus (HIV) infection as they are not able to clear virus. We hypothesized that an infusion of NK cells, supported by interleukin 2 (IL-2) or IL-15, could decrease virus-producing cells in the lymphatic tissues.

Methods: We conducted a phase 1 pilot study in 6 persons with HIV (PWH), where a single infusion of haploidentical related donor NK cells was given plus either IL-2 or N-803 (an IL-15 superagonist).

Article Synopsis
  • Total pancreatectomy with islet autotransplantation (TPIAT) is effective for pain relief in chronic pancreatitis but may lead to nutritional issues due to complete exocrine pancreatic insufficiency.
  • A study evaluated vitamin levels and nutritional status in 348 TPIAT recipients and found significant increases in deficiencies of vitamins A, D, and E one year post-surgery.
  • The study recommends ongoing nutritional monitoring and the use of pancreatic multivitamins to prevent vitamin deficiencies in TPIAT patients, particularly highlighting the correlation between being underweight and vitamin deficiencies.

Background: Cardiac output (CO) is a valuable proxy for perfusion, and governs volume responsiveness during resuscitation from distributive shock. The underappreciated venous system has nuanced physiology that confers valuable hemodynamic information. In this investigation, deconvolution of the central venous waveform by the fast Fourier transformation (FFT) algorithm is performed to assess its ability to constitute a CO surrogate in a porcine model of endotoxemia-induced distributive hypotension and resuscitation.

Background: In total pancreatectomy with islet auto-transplantation, successful diabetes outcomes are limited by islet loss from the instant blood mediated inflammatory response. We hypothesized that blockade of the inflammatory response with either etanercept or alpha-1-antitrypsin would improve islet function and insulin independence.

Methods: We randomized 43 participants to receive A1AT (90 mg/kg x 6 doses, n = 13), or etanercept (50 mg then 25 mg x 5 doses, n = 14), or standard care (n = 16), aiming to reduce detrimental effects of innate inflammation on early islet survival.
