Open or Not Open the Retroperitoneum: A Pandora's Box for Blunt High-Grade Pancreatic Trauma?

Introduction: The optimal management strategy for pancreatic trauma remains unclear. We aimed to determine whether the initial nonoperative management (NOM) strategy based on percutaneous drainage combined with endoscopic retrograde cholangiopancreatography guided stent placement would improve outcomes for blunt high-grade pancreatic trauma.

Methods: Patients with blunt abdominal trauma who were hemodynamically stable without signs of diffuse peritonitis were consecutively enrolled at a high-volume center.

A hybrid model of modal decomposition and gated recurrent units for short-term load forecasting.

Electrical load forecasting is important to ensuring power systems are operated both economically and safely. However, accurately forecasting load is difficult because of variability and frequency aliasing. To eliminate frequency aliasing, some methods set parameters that depend on experiences.

Initial suction drainage decreases severe postoperative complications after pancreatic trauma: A cohort study.

Background: Few studies have addressed the question of which drain types are more beneficial for patients with pancreatic trauma (PT).

Aim: To investigate whether sustained low negative pressure irrigation (NPI) suction drainage is superior to closed passive gravity (PG) drainage in PT patients.

Methods: PT patients who underwent pancreatic surgery were enrolled consecutively at a referral trauma center from January 2009 to October 2021.

Maternal weight and its association with risk of overweight in offspring: a trajectory analysis from a birth cohort in China.

Background: Most studies on the association of maternal pregnancy weight with offspring weight trajectory have a short follow-up time. This study aimed to explore the associations of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) with childhood weight trajectories in a 7-year birth cohort.

Methods: A total of 946 mother-child pairs (467 boys and 479 girls) from a longitudinal birth cohort in Tianjin City, China, were included in this study, ranging from pregnancy to offspring at 7 years.

A robust maximum correntropy forecasting model for time series with outliers.

It is of great significance to develop a robust forecasting method for time series. The reliability and accuracy of the traditional model are reduced because the series is polluted by outliers. The present study proposes a robust maximum correntropy autoregressive (MCAR) forecasting model by examining the case of actual power series of Hanzhong City, Shaanxi province, China.

Early systemic anticoagulation reduces hospital readmission in acute necrotizing pancreatitis patients: A retrospective cohort study.

Background: Early systemic anticoagulation (SAC) is a common practice in acute necrotizing pancreatitis (ANP), and its impact on in-hospital clinical outcomes had been assessed. However, whether it affects long-term outcomes is unknown. This study aimed to evaluate the effect of SAC on 90-day readmission and other long-term outcomes in ANP patients.

Involvement of transverse mesocolon is associated with development of colonic fistula in patients with acute necrotizing pancreatitis.

Background: Involvement of transverse mesocolon (TM) during acute necrotizing pancreatitis(ANP) indicates that inflammation has spread from retroperitoneal space to peritoneum. Nevertheless, the impact of TM involvement, as confirmed by contrast-enhanced computed tomography (CECT), on local complications and clinical outcomes was poorly investigated.

Purpose: This study aimed to explore the association between CECT-diagnosed TM involvement and the development of colonic fistula in a cohort of ANP patients.

Expert consensus on the monitoring and treatment of sepsis-induced immunosuppression.

Emerged evidence has indicated that immunosuppression is involved in the occurrence and development of sepsis. To provide clinical practice recommendations on the immune function in sepsis, an expert consensus focusing on the monitoring and treatment of sepsis-induced immunosuppression was developed. Literature related to the immune monitoring and treatment of sepsis were retrieved from PubMed, Web of Science, and Chinese National Knowledge Infrastructure to design items and expert opinions were collected through an online questionnaire.

Association of demographic and clinical factors with risk of acute pancreatitis: An exposure-wide Mendelian randomization study.

Background: The incidence of acute pancreatitis (AP) is increasing over years, which brings enormous economy and health burden. However, the aetiologies of AP and underlying mechanisms are still unclear. Here, we performed a two-sample Mendelian randomization (MR) analysis to investigate the associations between all reported possible risk factors and AP using publicly available genome-wide association study summary statistics.

Serum magnesium level as a predictor of acute kidney injury in patients with acute pancreatitis.

Background: Decreased serum magnesium (Mg) is commonly seen in critically ill patients. Hypomagnesemia is significantly more frequent in patients with severe acute pancreatitis. Acute kidney injury (AKI) in patients with acute pancreatitis (AP) is associated with an extremely high mortality.

A cohort autopsy study defines COVID-19 systemic pathogenesis.

Severe COVID-19 disease caused by SARS-CoV-2 is frequently accompanied by dysfunction of the lungs and extrapulmonary organs. However, the organotropism of SARS-CoV-2 and the port of virus entry for systemic dissemination remain largely unknown. We profiled 26 COVID-19 autopsy cases from four cohorts in Wuhan, China, and determined the systemic distribution of SARS-CoV-2.

Bioelectrical impedance analysis-guided fluid management promotes primary fascial closure after open abdomen: a randomized controlled trial.

Background: Fluid overload (FO) after resuscitation is frequent and contributes to adverse outcomes among postinjury open abdomen (OA) patients. Bioelectrical impedance analysis (BIA) is a promising tool for monitoring fluid status and FO. Therefore, we sought to investigate the efficacy of BIA-directed fluid resuscitation among OA patients.

Digenic Inheritance and Gene-Environment Interaction in a Patient With Hypertriglyceridemia and Acute Pancreatitis.

The etiology of hypertriglyceridemia (HTG) and acute pancreatitis (AP) is complex. Herein, we dissected the underlying etiology in a patient with HTG and AP. The patient had a 20-year history of heavy alcohol consumption and an 8-year history of mild HTG.

Predicting the mortality risk of acute respiratory distress syndrome: radial basis function artificial neural network model versus logistic regression model.

To predict the mortality of acute respiratory distress syndrome (ARDS) by using a radial basis function (RBF) artificial neural network (ANN) model. This study included 217 patients who were admitted between June 2013 and November 2019. The RBF ANN model and logistic regression (LR) model were based on twelve factors related to ARDS.

Chinese expert consensus on diagnosis and treatment of trauma-induced hypercoagulopathy.

Trauma-induced coagulopathy (TIC) is caused by post-traumatic tissue injury and manifests as hypercoagulability that leads to thromboembolism or hypocoagulability that leads to uncontrollable massive hemorrhage. Previous studies on TIC have mainly focused on hemorrhagic coagulopathy caused by the hypocoagulable phenotype of TIC, while recent studies have found that trauma-induced hypercoagulopathy can occur in as many as 22.2-85.

The aims of the study were to assess the contribution of resilience, coping style, and COVID-19 stress on the quality of life (QOL) in frontline health care workers (HCWs). The study was a cross-sectional surveyperformed among 309 HCWs in a tertiaryhospital during the outbreak of COVID-19 in China. Data were collected through an anonymous, self-rated questionnaire, including demographic data, a 10-item COVID-19 stress questionnaire, Generic QOL Inventory-74, Connor-Davidson Resilience Scale, and the Simplified Coping Style Questionnaire.

Self-consistent charging of PMMA thin film induced by a penetrating electron beam in electron microscopy.

The charging of the polymer thin film irradiated by penetrating electron beam (e-beam) is investigated, in parallel with the numerical simulation and experiment. The simulation is performed by combining scattering, drift, diffusion, trapping and recombination. Results show that, due to the electron emission the net charge near the surface is distribution positively, but negatively inside the film because of low electron mobility.

Early versus delayed intervention in necrotizing acute pancreatitis complicated by persistent organ failure.

Background: Current guidelines for the treatment of patients with necrotizing acute pancreatitis (NAP) recommend that invasive intervention for pancreatic necrosis should be deferred to 4 or more weeks from disease onset to allow necrotic collections becoming "walled-off". However, for patients showing signs of clinical deterioration, especially those with persistent organ failure (POF), it is controversial whether this delayed approach should always be adopted. In this study, we aimed to assess the impact of differently timed intervention on clinical outcomes in a group of NAP patients complicated by POF.

Charging effects of SiO thin film on Si substrate irradiated by penetrating electron beam.

In this work, the charging effect and induced conductivity of SiO thin films on Si substrate irradiated by penetrating electron beam (e-beam) are investigated based on numerical calculation and experiment. The numerical model is performed by considering the electron scattering, trapping, drift, diffusion and recombination, and solved by the Monte Carlo and finite difference method. The results show that, under e-beam irradiation, due to emission of secondary electrons (SEs) from the surface, the net charge density is positive near the surface, but negative inside the film.
