RESUMO
BACKGROUND: Propofol, a commonly used agent for short- and long-term sedation, is associated with acute pancreatitis. The main indirect mechanism of propofol-associated acute pancreatitis is by inducing hypertriglyceridemia. Patients with severe coronavirus disease 2019 (COVID-19) pneumonia often require prolonged mechanical ventilation and sedation. We examined the incidence rate of acute pancreatitis among critically ill adults with COVID-19 pneumonia on mechanical ventilation receiving propofol. In addition, we attempted to determine cutoff levels of serum triglycerides and doses of propofol that are predictive of propofol-associated acute pancreatitis. METHODS: This was a multicenter retrospective cohort study using a large dataset of hospitalized patients with COVID-19. The collected data included the number of days on propofol, cumulative doses of propofol, peak levels of serum triglycerides, serum lipase levels, and abdominal imaging findings. We used receiver-operating characteristic analysis in conjunction with Youden's index to identify the optimal thresholds for propofol administration parameters and levels of triglycerides that would provide maximal sensitivity and specificity for predicting acute pancreatitis. RESULTS: Out of 499 critically ill patients with COVID-19 pneumonia, 154 met the inclusion criteria. Six (4%) patients had suspected acute pancreatitis based on elevated serum lipase levels. Cutoff values greater than 688â mg/dL for peak level of triglycerides, 4.5 days on propofol, 3007â mg/day for average daily propofol dose, and 24â 113â mg for cumulative propofol dose were associated with high risk of suspected acute pancreatitis. The negative predictive values for suspected acute pancreatitis using these cutoffs ranged from 98% to 100%. CONCLUSIONS: Propofol use in critically ill COVID-19 patients is associated with a low incidence rate of acute pancreatitis. We identified cutoff values for serum triglycerides and cumulative propofol dose that are linked to higher risk of propofol-associated pancreatitis. More research is needed to examine the true incidence of propofol-associated pancreatitis and help develop optimal cutoff values for certain parameters to help guide safe propofol administration.
RESUMO
Primary gastric diffuse large B-cell lymphoma (PG-DLBCL) is a rare gastric malignant neoplasm. While the association between Heliobacter pylori infection and gastric mucosa-assisted lymphoid tissue lymphoma is well established, data supporting its association with DLBCL are less robust. Here we present a rare case of PG-DLBCL diagnosed with H. pylori. An 82-year-old man presented to clinic with complaints of worsening epigastric pain. He underwent an endoscopy which revealed 1 large nonbleeding gastric ulcer. Histopathological and immunohistochemical analysis confirmed PG-DLBCL. He was started on H. pylori eradication (HPE) and subsequently completed 6 cycles of R-mini-CHOP chemotherapy. Since then, the patient maintained clinical and radiological remission for more than a year without recurrence. PG-DLBCL is an aggressive Non-hodgkin lymphoma (NHL) that usually presents late. It has been shown that HPE without chemotherapy in DLBCL codiagnosed with H. pylori is not an effective strategy. Thus, the standard of care for patients would be HPE and chemotherapy as in our patient. More research is needed to better understand association between H. pylori and DLBCL.
RESUMO
BACKGROUND AND AIMS: Combined endoscopic mucosal resection (EMR) with endoscopic Full thickness resection (EFTR) is an emerging technique that has been developed to target colorectal polyps larger than 2 cm. We performed a systematic review and meta-analysis to evaluate this technique for the resection of large colorectal lesions. METHODS: We conducted a comprehensive search of multiple electronic databases from inception through August 2023, to identify studies that reported on hybrid FTR. A random-effects model was employed to calculate the overall pooled technical success, macroscopic complete resection, free vertical margins resection rate, adverse events, and recurrence on follow up. RESULTS: A total of 8 Study arms with 244 patients (30% women) were included in the analysis. The pooled technical success rate was 97% (95% CI 88%-100%, I2 = 79.93%). The pooled rate of macroscopic complete resection was achieved in 95% (95% CI 90%-99%, I2 = 49.98) with a free vertical margins resection rate 88% (95% CI, 78%-96%, I2 = 63.32). The overall adverse events rate was 2% (95% CI 0%-5%, I2 = 11.64) and recurrence rate of 6% (95% CI 2%-12%, I2=20.32). CONCLUSION: Combined EMR with EFTR is effective and safe for resecting large, and complex colorectal adenomas, offering a good alternative for high surgical risk patients. Regional heterogeneity was observed, indicating that outcomes may be impacted by differences in operator expertise and industry training certification across regions. Comparative studies that directly compare combined EMR with EFTR against alternative methods such as ESD and surgical resection are needed.

RESUMO
Amyloidosis is a rare multisystem disease due to deposition of abnormal protein fragments, and cardiac amyloidosis is progressive and difficult to diagnose due to its subtle and non-specific symptoms unless the physician maintains a high degree of suspicion. This case report focuses on amyloid deposition in the heart of an 84-year-old woman who presented with symptoms of uncompensated heart failure.
