Background: This study compares a laparoscopic skill training protocol without proficiency targets to the same protocol with explicit targets and notification of progress.
Methods: Fourteen surgery interns were randomized into 2 groups. The intervention group received task-specific proficiency criteria to guide practice. The control group did not. After training, participants were evaluated by blinded faculty during laparoscopic cholecystectomy.
Results: The control group met significantly fewer of the 7 LapSim (Surgical Science Sweden AB, Gotëborg) targets (mean = 1.14) than the intervention group (mean = 7.00; P = .001) and significantly fewer of the 5 video trainer targets (mean = .86) than the intervention group (mean = 5.00; P = .001). Ratings of depth perception, bimanual dexterity, efficiency, tissue handling, autonomy, and overall competence were higher for the intervention group. Effect sizes ranged from medium to large (.394-.981), indicating an impact of the proficiency-based training protocol.
Conclusions: Delineation of proficiency targets with reporting of progress improves interns' practice results, and appears to have a positive effect on their early operating room (OR) performance of laparoscopic cholecystectomy.

Preoperative iron therapy: Where are we?

Preoperative anemia affects one-third of patients undergoing major surgery and is associated with worse perioperative and postoperative outcomes; including length of hospital stay, allogeneic blood transfusion, morbidity, and mortality. Iron deficiency is the most common cause of anemia, and associative data suggests that preoperative correction of iron deficiency anemia could improve postoperative patient outcomes. However, data from randomized controlled trials (RCTs) do not appear to support the routine use of iron therapy to treat preoperative anemia.

Patients with cancer who receive allogeneic red blood cell transfusions are at risk of adverse reactions of varying severity. One of these reactions is immunomodulation, also known as transfusion-related immunomodulation. With the exact mechanism of transfusion related immunomodulation being unclear, storage lesions (both the cellular and cytokine component) are considered a major contributor.

Patient Blood Management evolved in recent years, focusing on the haematopoietic system as relevant to all disciplines of medicine. The allogeneic blood supply chain travels from donation, to fractionation, preservation, and storage, to therapeutic, established treatments, or prophylactics for a wide range of medical conditions. This supply chain 'connects' altruistic blood donors to patients in need, symbolising a 'gift relationship', emphasising the empathetic bond between donor and recipient.

Despite advances in procedural techniques and equipment, postdural puncture headache (PDPH) remains a serious complication of labour epidural analgesia after accidental dural puncture (ADP). Often considered a temporary inconvenience, PDPH can be debilitating in the short term. It can also be associated with chronic manifestations and serious complications.

Elevated serum uric acid (SUA) levels in pregnancy are linked to adverse outcomes, including preterm birth, preeclampsia, and low birth weight. To assess the predictive value of SUA levels in early pregnancy for adverse pregnancy outcomes (APOs). A cohort of 4,240 pregnant women admitted for delivery from January 2021 to December 2022 was analyzed.
