RESUMO
BACKGROUND: Perforated peptic ulcer (PPU) causes peritonitis and requires surgery based on disease severity. This study aimed to develop and validate a severity scale for PPU with generalized peritonitis. MATERIALS AND METHODS: This retrospective cohort study used a nationwide multi-center surgical database (2013-2020). Patients aged >15 years who underwent surgery for PPU with generalized peritonitis were included and categorized into the derivation (2013-2018) and two validation (2019 and 2020) cohorts. Possible severity predictors were selected via a literature review, and Lasso models were developed to predict severe postoperative adverse events with 2000 bootstrapping. Final variables for the scoring system were determined based on inclusion frequency (≥90%) in the Lasso models. Discrimination and accuracy were evaluated using c-statistics and calibration plots. Cutoff values for minimal postoperative adverse events were examined using negative predictive values. RESULTS: Among 12,513 patients included (1,202 underwent laparoscopic surgery), 533 (5.9%), 138 (7.6%), and 117 (6.9%) in the derivation and two validation cohorts experienced postoperative adverse events. Age, dyspnea at rest, preoperative sepsis, III/IV/V of American Society of Anesthesiologists physical status, and albumin and creatinine were selected for the final model. A 0-11 scoring system was developed with c-statistics of 0.812-0.819. Cutoff value was determined as 5, which predicted <3% probability of postoperative adverse events regardless of type of surgery. CONCLUSIONS: A score of <5 predicts minimal risks for postoperative adverse events and therefore would be clinically useful to determine type of surgery. Further studies are needed to validate the score.
RESUMO
We report here a case of postoperative recurrent adenosquamous carcinoma (ASC) of the esophagogastric junction (EGJ) treated with S-1 therapy. A 79-year-old woman was diagnosed with carcinoma of the EGJ. Thoracoscopic subtotal esophagectomy was performed, and pathological examination revealed advanced ASC with lymph node metastasis. Five months after surgery, multiple lung metastases and multiple lymph node metastases were observed, and the patient was treated with S-1 monotherapy, which showed partial response and may be effective for advanced ASC of the EGJ. On the other hand, immunohistological analysis of the tumors showed a relatively wide range of areas that could differentiate into both adenocarcinoma and squamous cell carcinoma, suggesting that tumor cells with multidifferentiation potential, or at least the ability to differentiate into both adeno-epithelial and squamous epithelial cells, were the likely source of the tumors.
RESUMO
PURPOSE: While follow-up CT and prophylactic embolization with angiography are often conducted during non-operative management (NOM) for BLSI, particularly in a high-grade injury, the utility of early repeated CT for preventing unexpected hemorrhage remains unclear. This study aimed to elucidate whether early follow-up computerized tomography (CT) within 7 days after admission would decrease unexpected hemostatic procedures on pediatric blunt liver and spleen injury (BLSI). METHODS: A post-hoc analysis of a multicenter observational cohort study on pediatric patients with BLSI (2008-2019) was conducted on those who underwent NOM, in whom the timing of follow-up CT were decided by treating physicians. The incidence of unexpected hemostatic procedure (laparotomy and/or emergency angiography for ruptured pseudoaneurysm) and complications related to BLSI were compared between patients with and without early follow-up CT within 7 days. Inverse probability weighting with propensity scores adjusted patient demographics, comorbidities, mechanism and severity of injury, initial resuscitation, and institutional characteristics. RESULTS: Among 1320 included patients, 552 underwent early follow-up CT. Approximately 25% of patients underwent angiography on the day of admission. The incidence of unexpected hemostasis was similar between patients with and without early repeat CT (8 [1.4%] vs. 6 [0.8%]; adjusted OR, 1.44 [0.62-3.34]; p = 0.40). Patients with repeat CT scans more frequently underwent multiple angiographies (OR, 2.79 [1.32-5.88]) and had more complications related to BLSI, particularly bile leak (OR, 1.73 [1.04-2.87]). CONCLUSION: Follow-up CT scans within 7 days was not associated with reduced unexpected hemostasis in NOM for pediatric BLSI.
RESUMO
BACKGROUND: The role of lactate level in selecting the timing of definitive surgery for isolated extremity fracture remains unclear. Therefore, we aimed to elucidate the use of preoperative lactate level for predicting early postoperative complications. METHODS: This was a single-center retrospective observational study of patients with isolated extremity fracture who underwent orthopedic surgery. Patients who underwent lactate level assessment within 24 h prior to surgery were included. The incidence of early postoperative complications was compared between patients with a preoperative lactate level of ≥ 2 and < 2 mmol/L. Moreover, subgroup analyses were performed based on the time from hospital arrival to surgery and fracture type. RESULTS: In total, 187 patients were included in the study. The incidence of postoperative complications was significantly higher in patients with a preoperative lactate level of ≥ 2 mmol/L than those with a preoperative lactate level of < 2 mmol/L. This result did not change after adjusting for age and severity. Further, a high preoperative lactate level was associated with a greater incidence of postoperative complications in patients who underwent definitive surgery within 6 h after arrival. CONCLUSION: A preoperative lactate level of ≥ 2 mmol/L was associated with a greater incidence of early postoperative complications in isolated extremity fractures. Nevertheless, this correlation was only observed among patients who underwent definitive fixation within 6 h after hospital arrival.

OBJECTIVE: Ischaemia-reperfusion (I/R) injury is a severe post-operative complication that triggers an inflammatory response and causes severe damage. Hydrogen gas has anti-oxidant and anti-apoptotic properties and has been shown to be safe in humans. The study aimed to investigate whether hydrogen gas protects against skeletal muscle I/R injury. METHODS: Experimental basic research using mice. A total of 160 eight to 10 week old albino laboratory bred strain of house mice (25.8 ± 0.68 g) were used in this study. The mice were cable tied to the hindlimb under anaesthesia and then placed in an anaesthesia box filled with air and 2% isoflurane (control group); 80 mice were additionally subjected to 1.3% hydrogen gas in this mix (hydrogen group). After two hours, the cable ties were removed to initiate reperfusion, and hydrogen inhalation lasted for six hours in the hydrogen group. After six hours, the mice were taken out of the box and kept in cages under standard conditions until time for observation at 16 different time points after reperfusion: zero, two, four, six, eight, and 10 hours and one, two, three, four, five, six, seven, 14, 21, and 28 days. Five mice were sacrificed using excess anaesthesia at each time point, and the bilateral hindlimb tissues were harvested. The inflammatory effects of the I/R injury were assessed by evaluating serum interleukin-6 concentrations using enzyme linked immunosorbent assay, as well as histological and immunohistochemical analyses. Untreated mice with I/R injury were used as controls. RESULTS: Hydrogen gas showed protective effects associated with a reduction in inflammatory cell infiltration (neutrophils, macrophages, and lymphocytes), a reduced area of damaged muscle, maintenance of normal muscle cells, and replacement of damaged muscle cells with neoplastic myocytes. CONCLUSION: Inhalation of hydrogen gas had a protective effect against hindlimb I/R injury in mice, in part by reducing inflammatory cell infiltration and in part by preserving normal muscle cells.

PURPOSE: This study aimed to elucidate whether immediate angiography within 30 min is associated with lower in-hospital mortality compared with non-immediate angiography. MATERIALS AND METHODS: We conducted a retrospective cohort study using a nationwide trauma databank (2019-2020). Adult trauma patients who underwent emergency angiography within 12 h after hospital arrival were included. Patients who underwent surgery before angiography were excluded. Immediate angiography was defined as one performed within 30 min after arrival (door-to-angio time ≤ 30 min). In-hospital mortality and non-operative management (NOM) failure were compared between patients with immediate and non-immediate angiography. Inverse probability weighting with propensity scores was conducted to adjust patient demographics, injury mechanism and severity, vital signs on hospital arrival, and resuscitative procedures. A restricted cubic spline curve was drawn to reveal survival benefits by door-to-angio time. RESULTS: Among 1,455 patients eligible for this study, 92 underwent immediate angiography. Angiography ≤ 30 min was associated with decreased in-hospital mortality (5.0% vs 11.1%; adjusted odds ratio [OR], 0.42 [95% CI, 0.31-0.56]; p < 0.001), as well as lower frequency of NOM failure: thoracotomy and laparotomy after angiography (0.8% vs. 1.8%; OR, 0.44 [0.22-0.89] and 2.6% vs. 6.5%; OR, 0.38 [0.26-0.56], respectively). The spline curve showed a linear association between increasing mortality and prolonged door-to-angio time in the initial 100 min after arrival. CONCLUSION: In trauma patients, immediate angiography ≤ 30 min was associated with lower in-hospital mortality and fewer NOM failures. LEVEL OF EVIDENCE: Level 3b, non randomized controlled cohort/follow up study.

PURPOSE: Vital signs are important for predicting clinical outcomes in patients with trauma. However, their accuracy can be affected in older adults because hemodynamic changes are less obvious. This study aimed to examine the usefulness of changes in vital signs during transportation in predicting the need for hemostatic treatments in older patients with trauma. METHODS: This retrospective cohort study was conducted using data from the Japan Trauma Data Bank (2004-2019). Patients aged ≥ 65 years who were hemodynamically stable at the scene were included in this study. The incidence of emergency surgery within 12 h after hospital arrival was compared between patients with delta Shock Index (dSI) > 0.1 and those with dSI ≤ 0.1. Predicting ability was examined after adjusting for patient demographics, comorbidities, vital signs at the scene and on hospital arrival, Injury Severity Score, and abbreviated injury scale in each region. RESULTS: Among the 139,242 patients eligible for the study, 3,701 underwent urgent hemostatic surgery within 12 h. Patients with dSI > 0.1 showed a significantly higher incidence of emergency surgery than those with dSI ≤ 0.1 (871/16,549 [5.3%] vs. 2,830/84,250 [3.4%]; odds ratio (OR), 1.60 [1.48-1.73]; adjusted OR, 1.22 [1.08-1.38]; p = 0.001). The relationship between high dSI and a higher incidence of intervention was observed in patients with hypertension and those with decreased consciousness on arrival. CONCLUSION: High dSI > 0.1 was significantly associated with a higher incidence of urgent hemostatic surgery in older patients.

INTRODUCTION: Early appropriate care (EAC) is widely accepted as a safe strategy to perform early definitive fracture fixation, and good clinical outcomes have been reported in selected, multiply injured patients, although the optimal candidate for early definitive fixation (EDF) has not been validated. The aim of this study was to identify simple clinical parameters to help select patients who could undergo EDF. METHODS: Patients with extremity injuries who underwent open reduction and internal fixation were retrospectively identified, using data from the Japan Trauma Data Bank (JTDB). Age, vital signs on hospital presentation, and the injury severity score (ISS) were examined by transforming these variables to binary categories. Patients were divided into categories based on these variables, and in-hospital mortality was compared between patients treated with EDF (EDF group) and those treated without EDF (non-EDF group) in each category. RESULTS: Of the 12,735 patients who were eligible for the analyses, 3706 (29.1 %) were managed with EDF. In-hospital mortality was significantly higher in the EDF group than in the non-EDF group among patients with a low Glasgow Coma Scale (GCS) score (<13), low systolic blood pressure (sBP) (<90 mmHg), and ISS≥15, whereas in-hospital mortality was comparable between the EDF and non-EDF groups among patients with GCS scores ≥13, sBP ≥90 mmHg, and ISS <15. DISCUSSION: In this large nationwide database of trauma patients, EDF was performed without affecting mortality in patients with GCS scores ≥13 and sBP ≥90 mmHg on hospital presentation, as well as ISS <15. These parameters might be useful as screening tools to select the candidates who could be treated with EDF safely.
RESUMO
BACKGROUND: Primary fascia closure is often difficult following an open abdomen (OA). While negative-pressure wound therapy (NPWT) is recommended to enhance successful primary fascia closure, the optimal methods and degree of negative pressure remain unclear. This study aimed to elucidate optimal methods of NPWT as a tentative abdominal closure for OA to achieve primary abdominal fascia closure. MATERIALS AND METHODS: A multicenter, retrospective, cohort study of adults who survived OA greater than 48 h was conducted in 12 institutions between 2010 and 2022. The achievement of primary fascia closure and incidence of enteroatmospheric fistula were examined based on methods (homemade, superficial NPWT kit, or open-abdomen kit) or degrees of negative pressure (<50, 50-100, or >100 mmHg). A generalized estimating equation was used to adjust for age, BMI, comorbidities, etiology for laparotomy requiring OA, vital signs, transfusion, severity of critical illness, and institutional characteristics. RESULTS: Of the 279 included patients, 252 achieved primary fascia closure. A higher degree of negative pressure (>100 mmHg) was associated with fewer primary fascia closures than less than 50 mmHg [OR, 0.18 (95% CI: 0.50-0.69), P =0.012] and with more frequent enteroatmospheric fistula [OR, 13.83 (95% CI: 2.30-82.93)]. The methods of NPWT were not associated with successful primary fascia closure. However, the use of the open-abdomen kit was related to a lower incidence of enteroatmospheric fistula [OR, 0.02 (95% CI: 0.00-0.50)]. CONCLUSION: High negative pressure (>100 mmHg) should be avoided in NPWT during tentative abdominal closure for OA.

A 79-year-old man was diagnosed with esophagogastric junction adenocarcinoma, cT3N3M0, cStage â ¢, including enlarged lymph node metastases(Bulky N)in the middle mediastinum and intraperitoneal. A total of 2 cycles of S-1 plus oxaliplatin(SOX)was administered. After neoadjuvant chemotherapy, the primary tumor and enlarged lymph nodes had greatly decreased in size. Subsequently, thoracoscopic subtotal esophagectomy and reconstruction with a gastric tube were performed. Histopathological examinations showed no residual cancer cells in the primary lesion and dissected lymph nodes (pathological complete response). Preoperative chemotherapy containing SOX could be a useful treatment strategy for patients with esophagogastric junction adenocarcinoma with enlarged lymph node metastasis.

A considerable number of patients with mild traumatic brain injury have been known to "talk and die." Serial neurological examinations, however, have been the only method of determining the necessity of repeat computed tomography (CT), and no validated method has been available to predict early deterioration of minor head injury. This study aimed to evaluate the association between hypertension and bradycardia, a classic sign of raised intracranial pressure (Cushing reflex) on hospital arrival and determine the clinical consequences of minor head injury after blunt trauma. We created a new Cushing Index (CI) by dividing the systolic blood pressure by the heart rate (equaling the inverse number of the Shock Index, a score for hemodynamic stability) and hypothesized that a high CI would predict surgical intervention for deterioration and in-hospital death among patients with minor head injury. To test our hypothesis, a retrospective observational study was conducted using a nationwide trauma database. Accordingly, adult blunt trauma with minor head injury (defined as a Glasgow Coma Scale of 13-15 and Abbreviated Injury Scale score of ≥2 in the head) who were transported directly from the scene by ambulances were included. Among the 338,744 trauma patients identified in the database, 38,844 were eligible for inclusion. A restricted cubic spline regression curve for risks of in-hospital death was created using the CI. Thereafter, the thresholds were determined based on inflection points of the curve, and patients were divided into low-, intermediate-, and high-CI groups. Patients with high CI showed significantly higher in-hospital mortality rates compared with those with intermediate CI (351 [3.0%] vs. 373 [2.3%]; odds ratio [OR] = 1.32 [1.14-1.53]; p < 0.001). Patients with high index also had a higher incidence of emergency cranial surgery within 24h after arrival than those with an intermediate CI (746 [6.4%] vs. 879 [5.4%]; OR = 1.20 [1.08-1.33]; p < 0.001). In addition, patients with low CI (equal to high Shock Index, meaning hemodynamically unstable) showed higher in-hospital death compared with those with intermediate CI (360 [3.3%] vs. 373 [2.3%]; p < 0.001). In conclusion, a high CI (high systolic blood pressure and low heart rate) on hospital arrival would be helpful in identifying patients with minor head injury who might experience deterioration and need close observation.

Crush syndrome induced by skeletal muscle compression causes fatal rhabdomyolysis-induced acute kidney injury (RIAKI) that requires intensive care, including hemodialysis. However, access to crucial medical supplies is highly limited while treating earthquake victims trapped under fallen buildings, lowering their chances of survival. Developing a compact, portable, and simple treatment method for RIAKI remains an important challenge. Based on our previous finding that RIAKI depends on leukocyte extracellular traps (ETs), we aimed to develop a novel medium-molecular-weight peptide to provide clinical treatment of Crush syndrome. We conducted a structure-activity relationship study to develop a new therapeutic peptide. Using human peripheral polymorphonuclear neutrophils, we identified a 12-amino acid peptide sequence (FK-12) that strongly inhibited neutrophil extracellular trap (NET) release in vitro and further modified it by alanine scanning to construct multiple peptide analogs that were screened for their NET inhibition ability. The clinical applicability and renal-protective effects of these analogs were evaluated in vivo using the rhabdomyolysis-induced AKI mouse model. One candidate drug [M10Hse(Me)], wherein the sulfur of Met10 is substituted by oxygen, exhibited excellent renal-protective effects and completely inhibited fatality in the RIAKI mouse model. Furthermore, we observed that both therapeutic and prophylactic administration of M10Hse(Me) markedly protected the renal function during the acute and chronic phases of RIAKI. In conclusion, we developed a novel medium-molecular-weight peptide that could potentially treat patients with rhabdomyolysis and protect their renal function, thereby increasing the survival rate of victims affected by Crush syndrome.

BACKGROUND: Immediate whole-body CT (about 10â min after arrival) in an all-in-one resuscitation room equipped with CT has been found to be associated with shorter time to haemostasis and lower in-hospital mortality. The aim of this study was to elucidate the benefits of immediate whole-body CT after hospital arrival in patients with severe trauma with the hypothesis that immediate CT within 10â min is associated with lower in-hospital mortality. METHOD: This retrospective cohort study of patients with an injury severity score of more than 15 who underwent whole-body CT was conducted using the Japanese Trauma Databank (2019-2020). An immediate CT was conducted within 10â min after arrival. In-hospital mortality, frequency of subsequent surgery, and time to surgery were compared with immediate and non-immediate CT. Inverse probability weighting was conducted to adjust for patient backgrounds, including mechanism and severity of injury, prehospital treatment, vital signs, and institutional characteristics. RESULTS: Among the 7832 patients included, 646 underwent immediate CT. Immediate CT was associated with lower in-hospital mortality (12.5 versus 15.7 per cent; adjusted OR 0.77 (95 per cent c.i. 0.69 to 0.84); P < 0.001) and fewer damage-control surgeries (OR 0.75 (95 per cent c.i. 0.65 to 0.87)). There was a 10 to 20â min difference in median time to craniotomy, laparotomy, and angiography. These benefits were observed regardless of haemodynamic instability on hospital arrival, while they were identified only in elderly patients with severe injury and altered consciousness. CONCLUSION: Immediate CT within 10â min after arrival was associated with decreased in-hospital mortality in severely injured trauma patients.

Background: Although pump-controlled retrograde trial off (PCRTO) is a practical method for weaning from venoarterial extracorporeal membrane oxygenation (VA-ECMO), its advantages and safety for patients with pulmonary embolism are not yet reported. Case Presentation: A 62-year-old man with coronavirus disease 2019 experienced sudden cardiac arrest, and VA-ECMO was introduced. After confirming a massive acute pulmonary embolism, unfractionated heparin treatment was initiated. On day 6, the patient was confirmed stable with a flow rate of 1.0 L/min. However, decannulation led to cardiac arrest and reintroduction of VA-ECMO. After further treatment, a residual thrombus was observed, and pulmonary arterial pressure remained high. On day 23, ECMO was decannulated successfully after a weaning test with PCRTO, which simulated ECMO withdrawal by generating a partial arteriovenous shunt. Conclusion: PCRTO is a feasible weaning strategy and can be considered for patients with uncertain cardiorespiratory recovery.
RESUMO
BACKGROUND: The effect of the surgical sealant AQUABRID on outcomes after acute aortic dissection repair has not been evaluated. The objective of this study was to examine whether the use of AQUABRID affects the volume of intraoperative blood transfusion or operative time in patients undergoing emergency surgery to repair acute aortic dissection. METHODS: A multicenter retrospective cohort study from January 2007 to December 2021. A total of 399 patients underwent emergency acute aortic dissection repair. Propensity score matching was used to adjust for the type of surgery and other patient characteristics. RESULTS: A total of 387 of the eligible 399 patients were included in this study and propensity score matching yielded 94 patients for whom characteristics were not significantly different between the two groups. The type of surgery was exactly matched (ascending aorta replacement: 19 [40%]; partial arch replacement: 13 [28%]; total arch replacement: 15 [32%] in each group). Within the matched cohort, there was a statistically significant difference in the volume of intraoperative blood transfusion. (AQUABRID vs. control: 34 [26-38] vs. 50 [38-60] U in Japan, p = .03). Operating time was significantly shorter in the AQUABRID group (total operation: mean ± SD, 343 ± 92 vs. 402 ± 161 min, p = .03; reconstruction for arch vessels: 29 ± 17 vs. 56 ± 22, p < .01). The rate of postoperative complications was comparable in the two groups. Failure to use AQUABRID was a significant predictor of the need for massive transfusion (>40 U) (odds ratio: 7.20; 95% confidence interval: 2.56-20.23; p < .01). CONCLUSIONS: The use of AQUABRID during emergency acute aortic dissection repair significantly decreased the volume of intraoperative blood transfusion and the duration of surgery.

INTRODUCTION: Open abdomen (OA) is a widely used technique for managing abdominal organ injury, abdominal compartment syndrome, and abdominal sepsis. While various methods have contributed to successful primary closure of the abdominal fascia after OA, some patients still develop enteroatmospheric fistulas that impede abdominal fascia closure. We report a case of successful epithelialization of the incision by sequential partial split-thickness skin grafting (STSG) in a patient who had failure in primary abdominal fascia closure due to enteroatmospheric fistulas after OA for incisional dehiscence and anastomotic leakage. PRESENTATION OF CASE: A 73-year-old male patient underwent pancreaticoduodenectomy for duodenal adenocarcinoma. The abdominal incision was then necrosed and dehisced due to anastomotic leakage on postoperative day (POD) 6, and multiple intra-abdominal lavages with OA were performed. On POD 15, the patient developed enteroatmospheric fistulas; thus, primary fascia closure was considered impossible. On PODs 72 and 106, STSG was conducted on the granulation tissue at the incisional wound, and complete epithelialization was achieved on POD 111. DISCUSSION: Sequential partial STSG only needed basic surgical skills and standard devices for surgery. CONCLUSION: We reported the case with successful epithelialization of the incision by sequential partial STSG, in which primary abdominal fascia closure was failed due to enteroatmospheric fistulas after OA for incisional dehiscence and anastomotic leakage.
RESUMO
Coronary artery aneurysm with coronary arteriovenous fistula is a relatively rare clinical setting. We report a surgical case of a 69-year-old male with a giant coronary artery aneurysm, finding coronary arteriovenous fistula on computed tomography (CT). We performed complete aneurysm excision and coronary artery bypass grafting with the left internal thoracic artery to the posterolateral branch. The fistula was located between the giant aneurysm on the circumflex artery and the coronary vein close to the coronary sinus, closed with aneurysm sac. The postoperative CT found no residual aneurysm and fistula. However, the great cardiac vein was thrombosed, and the impeded venous flow by the thrombus seemed to reduce the left ventricular ejection fraction (LVEF). Four months after the operation, the LVEF improved to the preoperative level.

BACKGROUND: The discussion is ongoing about appropriate indications for laparoscopic surgery in trauma patients. As timing and risks of conversion to laparotomy remain unclear, we aimed to elucidate characteristics of and risks for conversion following laparoscopic surgery, using a nationwide database. METHODS: A retrospective observational study was conducted, using Japanese Trauma Data Bank (2004-2018). We included adult trauma patients who underwent laparoscopic surgery as an initial surgical intervention. Conversion to laparotomy was defined as laparotomy at the initial surgery. Patient demographics, mechanism and severity of injury, injured organs, timing of surgery, and clinical outcomes were compared between patients with and without conversion. Risks for conversion were analyzed focusing on indications for laparoscopic surgery, after adjusting patient and institution characteristics. RESULTS: Among 444 patients eligible for the study, 31 required conversions to laparotomy. The number of laparoscopic surgeries gradually increased over the study period (0.5-4.5% of trauma laparotomy), without changes in conversion rates (5-10%). Patients who underwent conversion had more severe abdominal injuries compared with those who did not (AIS 3 vs 2). While length of hospital stay and in-hospital mortality were comparable, abdominal complications were higher among patients with conversion (12.9 vs. 2.9%), particularly when laparoscopy was performed for peritonitis (OR, 22.08 [5.11-95.39]). A generalized estimating equation model adjusted patient background and identified hemoperitoneum and peritoneal penetration as risks for conversion (OR, 24.07 [7.35-78.75] and 8.26 [1.20- 56.75], respectively). CONCLUSIONS: Trauma laparoscopy for hemoperitoneum and peritoneal penetration were associated with higher incidence of conversion to open laparotomy.

Coronavirus disease 2019 (COVID-19) is a recently-emerged infectious disease that has caused millions of deaths, where comprehensive understanding of disease mechanisms is still unestablished. In particular, studies of gene expression dynamics and regulation landscape in COVID-19 infected individuals are limited. Here, we report on a thorough analysis of whole blood RNA-seq data from 465 genotyped samples from the Japan COVID-19 Task Force, including 359 severe and 106 non-severe COVID-19 cases. We discover 1169 putative causal expression quantitative trait loci (eQTLs) including 34 possible colocalizations with biobank fine-mapping results of hematopoietic traits in a Japanese population, 1549 putative causal splice QTLs (sQTLs; e.g. two independent sQTLs at TOR1AIP1), as well as biologically interpretable trans-eQTL examples (e.g., REST and STING1), all fine-mapped at single variant resolution. We perform differential gene expression analysis to elucidate 198 genes with increased expression in severe COVID-19 cases and enriched for innate immune-related functions. Finally, we evaluate the limited but non-zero effect of COVID-19 phenotype on eQTL discovery, and highlight the presence of COVID-19 severity-interaction eQTLs (ieQTLs; e.g., CLEC4C and MYBL2). Our study provides a comprehensive catalog of whole blood regulatory variants in Japanese, as well as a reference for transcriptional landscapes in response to COVID-19 infection.
