RESUMO
BACKGROUND: Whether the ramped or sniffing laryngoscopy position is better for tracheal intubation is unclear. This study aimed to determine the efficacy and safety of tracheal intubation in the ramped versus sniffing position. METHODS: We conducted a systematic review and meta-analysis of randomized clinical trials to compare the ramped position with the sniffing position for tracheal intubation. We searched the databases of Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Excerpta Medica Database (Embase), ClinicalTrials.gov, and World Health Organization Clinical Trials Registry Platform up to December 2018. We included randomized-controlled trials, trials of participants who required tracheal intubation in any setting, and that compared tracheal intubation in the ramped and the sniffing positions. Two authors independently screened the trials, extracted the data, and assessed the risk of bias. We conducted the meta-analysis using the random-effects model to calculate the pooled risk ratio with 95% confidence interval. RESULTS: Of the 2631 titles/abstracts screened, three studies (representing 513 patients) were included in the meta-analysis. The pooled risk ratio with 95% confidence interval (CI) of the sniffing versus the ramped position was as follows: a first successful attempt, 0.97 (95% CI, 0.86-1.09; I2 = 55%); laryngoscopy attempts ≤2, 1.08 (95% CI, 0.88-1.31; I2 = 93%); and good glottic view with Cormack-Lehane grade ≤ 2, 0.86 (95% CI, 0.69-1.07; I2 = 86%). CONCLUSIONS: This systematic review and meta-analysis indicated no favorable aspects of the ramped position as compared to the sniffing position. Thus, further research is warranted to identify which is better in tracheal intubation. TRIAL REGISTRATION: PROSPERO identifier, CRD42019116819.

Instantaneous rigor is the immediate appearance of rigor mortis after cardiac arrest. To our knowledge, no previous reports exist on resuscitation of such patients. A young athlete suddenly collapsed with cardiac arrest during a marathon; his legs stiffened with instantaneous rigorlike stiffness. This stiffening provoked hyperkalemia, rhabdomyolysis, and multiple organ failure. We decided to amputate both legs, with venoarterial extracorporeal membrane oxygenation support. The patient recovered and was discharged without neurologic impairment. This rare case highlights the potentially significant effect of instantaneous rigor.

Anterior choroidal artery (AchA) infarction remains a challenging diagnosis although it was first described almost 100 years prior. N-isopropyl-p-[123I]-iodoamphetamine single-photon emission computed tomography (123I-IMP SPECT) and 7 Tesla magnetic resonance angiography (7T-MRA) are not routinely performed in cases of AchA infarction. Therefore, the application of 123I-IMP SPECT and 7T-MRA for AchA infarction has not been reported previously. A 67-year-old man presented with disturbed consciousness, gaze preference to the left, aphasia, right homonymous hemianopia, and right hemiparesis. Brain magnetic resonance imaging revealed infarction of the left posterior limb of the internal capsule. Left middle cerebral artery was clearly seen on MRA. However, 123I-IMP SPECT on day 13 showed cortical hypoperfusion which indicated thalamus involvement with neural deactivation. Additionally, 7T-MRA on day 15 revealed an intact left AchA suggesting reperfusion. The neurological deficits improved gradually after treatment and rehabilitation. This case demonstrates AchA infarction with cortical hypoperfusion associated with thalamus involvement, which was clarified by performing 123I-IMP SPECT and 7T-MRA. Perfusion analysis and evaluation of detailed vascular anatomy in stroke can be expected to elucidate pathological conditions.

BACKGROUND: In acute encephalopathy, deterioration of the condition can be rapid, and early intervention is essential to prevent progression of the disease. However, in the acute period, differentiating acute encephalopathy from febrile seizures is difficult. Thus, an early diagnostic marker has been sought to enable early intervention. Proton nuclear magnetic resonance ((1)H NMR) spectroscopy is used to study the chemical characteristics of biological fluids such as cerebrospinal fluid (CSF). The purpose of this study was to ascertain if pattern recognition of (1)H NMR spectra could differentiate CSF obtained from patients with acute encephalopathy and febrile seizures. METHODS: CSF was obtained from patients with acute encephalopathy (n = 4), complex febrile seizures (n = 9), and simple febrile seizures (n = 9). RESULTS: NMR spectra of CSF did not visually differ across the three groups. Spectral data were analyzed by partial least squares discriminant analysis and visualized by plotting the partial least squares scores of each sample. The three patient groups clustered separately on the plots. CONCLUSION: In this preliminary study, we were able to visualize different characteristics of CSF obtained from patients with acute encephalopathy and simple and complex febrile seizures using pattern recognition analysis of (1)H NMR data.

OBJECTIVE: To identify the influence of adverse drug events (ADEs) on morbidity and mortality in intensive care units (ICUs). DESIGN: A prospective cohort study. SETTING: ICU setting at three acute care hospitals in Japan. PARTICIPANTS: All patients aged ≥15 years were admitted to all ICUs during a 6-month study period. INTERVENTION: No intervention. MAIN OUTCOME MEASURES: Mortality in the ICUs and the length of the ICU stay. . RESULTS: We included 459 patients with a total of 3231 patient-days. Ninety-nine ADEs occurred in 70 patients (15%), so that the incidence of ADEs was 30.6 per 1000 patient-days and 21.6 ADEs per 100 admissions. Seventy-three patients (16%) died during their ICU stay. Excluding 38 deaths within 3 days after admission, 12 patients (17%) died among the 70 patients who had at least one ADE during their ICU stay and 23 (7%) died among 351 without an ADE (P = 0.003). The median ICU length of stay was 3 days. Excluding 73 patients who died during their ICU stay, the median ICU stay of patients with at least one ADE was 13 days, while it was only 2 days in the remainder (P < 0.0001). ADEs were associated with longer length of ICU stay but not with mortality even after adjusting for patients' severity of illness. CONCLUSIONS: ADEs were common in ICUs and significantly associated with longer length of ICU stay but did not influence on mortality.

Hepatitis C virus (HCV) reinfects liver allografts in transplant recipients by replicating immediately after transplantation, causing a rapid increase in blood serum HCV RNA levels. We evaluated dynamic changes in the viral genetic complexity after HCV reinfection of the graft liver; we also identified the characteristics of replicating HCV clones using a massively parallel ultradeep sequencing technique to determine the full-genome HCV sequences in the liver and serum specimens of five transplant recipients with genotype 1b HCV infection before and after liver transplantation. The recipients showed extremely high genetic heterogeneity before transplantation, and the HCV population makeup was not significantly different between the liver and blood serum specimens of the individuals. Viral quasispecies complexity in serum was significantly lower after liver transplantation than before it, suggesting that certain HCV clones selectively proliferated after transplantation. Defective HCV clones lacking the structural region of the HCV genome did not increase in number, and full-genome HCV clones selectively increased in number immediately after liver transplantation. A re-increase in the same defective clone existing before transplantation was detected 22 months after transplantation in one patient. Ultradeep sequencing technology revealed that the genetic heterogeneity of HCV was reduced after liver transplantation. Dynamic changes in defective HCV clones after liver transplantation indicate that these clones have important roles in the HCV life cycle.

Although the risks faced by passengers in near-side lateral collisions are understood, and despite the presence of side airbags for injury prevention, passengers involved in far-side lateral collisions also suffer serious and fatal injuries. The objective of this study was to determine the independent predictive factors of fatality of motor vehicle passengers involved in far-side lateral collisions. Using 2010 records from the National Automotive Sampling System/Crashworthiness Data System (NASS/CDS), we selected 86 fatal and 325 non-fatal passengers with an Abbreviated Injury Scale (AIS) score of 2 or more. The background and injury severity of the passengers and collision characteristics were compared between the two groups. In a multivariable logistic regression analysis, variables independently associated with fatalities were female sex (Ref, male) (odds ratio [OR], 0.396), age (OR, 1.029), body mass index (OR, 1.057), total delta-V (OR, 1.031), head AIS score (OR, 1.679), chest AIS score (OR, 1.330), and abdomen AIS score (OR, 1.294). This is the first report to determine factors affecting fatality in passengers involved in far-side lateral collisions. Improving the safety of the vehicle interior, such as by including additional seatbelt systems or a side airbag that deploys between seats, might help to avoid fatalities, and reduce injury severity.
RESUMO
The aldehyde degrading function of the ALDH2 enzyme is impaired by Glu504Lys polymorphisms (rs671, termed A allele), which causes alcohol flushing in east Asians, and elevates the risk of esophageal cancer among habitual drinkers. Recent studies suggested that the ALDH2 variant may lead to higher levels of DNA damage caused by endogenously generated aldehydes. This can be a threat to genome stability and/or cell viability in a synthetic manner in DNA repair-defective settings such as Fanconi anemia (FA). FA is an inherited bone marrow failure syndrome caused by defects in any one of so far identified 22 FANC genes including hereditary breast and ovarian cancer (HBOC) genes BRCA1 and BRCA2. We have previously reported that the progression of FA phenotypes is accelerated with the ALDH2 rs671 genotype. Individuals with HBOC are heterozygously mutated in either BRCA1 or BRCA2, and the cancer-initiating cells in these patients usually undergo loss of the wild-type BRCA1/2 allele, leading to homologous recombination defects. Therefore, we hypothesized that the ALDH2 genotypes may impact breast cancer development in BRCA1/2 mutant carriers. We genotyped ALDH2 in 103 HBOC patients recruited from multiple cancer centers in Japan. However, we were not able to detect any significant differences in clinical stages, histopathological classification, or age at clinical diagnosis across the ALDH2 genotypes. Unlike the effects in hematopoietic cells of FA, our current data suggest that there is no impact of the loss of ALDH2 function in cancer initiation and development in breast epithelium of HBOC patients.

Many countries are facing an aging population. As people live longer, surgeons face the prospect of operating on increasingly older patients. Traditional teaching is that with older age, these patients face an increased risk of mortality and morbidity, even to a level deemed too prohibitive for surgery. However, this is not always true. An active 90-year-old patient can be much fitter than an overweight, sedentary 65-year-old patient with comorbidities. Recent literature shows that frailty-an age-related cumulative decline in multiple physiological systems, is therefore a better predictor of mortality and morbidity than chronological age alone. Despite recognition of frailty as an important tool in identifying vulnerable surgical patients, many surgeons still shun objective tools. The aim of this position paper was to perform a review of the existing literature and to provide recommendations on emergency laparotomy and in frail patients. This position paper was reviewed by an international expert panel composed of 37 experts who were asked to critically revise the manuscript and position statements. The position paper was conducted according to the WSES methodology. We shall present the derived statements upon which a consensus was reached, specifying the quality of the supporting evidence and suggesting future research directions.

BACKGROUND: Diaphragmatic hernia (DH) presenting acutely can be a potentially life-threatening condition. Its management continues to be debatable. METHODS: A bibliographic search using major databases was performed using the terms "emergency surgery" "diaphragmatic hernia," "traumatic diaphragmatic rupture" and "congenital diaphragmatic hernia." GRADE methodology was used to evaluate the evidence and give recommendations. RESULTS: CT scan of the chest and abdomen is the diagnostic gold standard to evaluate complicated DH. Appropriate preoperative assessment and prompt surgical intervention are important for a clinical success. Complicated DH repair is best performed via the use of biological and bioabsorbable meshes which have proven to reduce recurrence. The laparoscopic approach is the preferred technique in hemodynamically stable patients without significant comorbidities because it facilitates early diagnosis of small diaphragmatic injuries from traumatic wounds in the thoraco-abdominal area and reduces postoperative complications. Open surgery should be reserved for situations when skills and equipment for laparoscopy are not available, where exploratory laparotomy is needed, or if the patient is hemodynamically unstable. Damage Control Surgery is an option in the management of critical and unstable patients. CONCLUSIONS: Complicated diaphragmatic hernia is a rare life-threatening condition. CT scan of the chest and abdomen is the gold standard for diagnosing the diaphragmatic hernia. Laparoscopic repair is the best treatment option for stable patients with complicated diaphragmatic hernias. Open repair is considered necessary in majority of unstable patients in whom Damage Control Surgery can be life-saving.

Enhanced perioperative care protocols become the standard of care in elective surgery with a significant improvement in patients' outcome. The key element of the enhanced perioperative care protocol is the multimodal and interdisciplinary approach targeted to the patient, focused on a holistic approach to reduce surgical stress and improve perioperative recovery. Enhanced perioperative care in emergency general surgery is still a debated topic with little evidence available. The present position paper illustrates the existing evidence about perioperative care in emergency surgery patients with a focus on each perioperative intervention in the preoperative, intraoperative and postoperative phase. For each item was proposed and approved a statement by the WSES collaborative group.

BACKGROUND: Despite the call to enhance accuracy and value of operation records few international recommended minimal standards for operative notes documentation have been described. This study undertook a systematic review of existing operative reporting systems for laparoscopic cholecystectomy (LC) to fashion a comprehensive, synoptic operative reporting template for the future. METHODS: A search for all relevant articles was conducted using PubMed version of Medline, Scopus and Web of Science databases in June 2021, for publications from January 1st 2011 to October 25th 2021, using the keywords: laparoscopic cholecystectomy AND operation notes OR operative notes OR proforma OR documentation OR report OR narrative OR audio-visual OR synoptic OR digital. Two reviewers (NOC, GMC) independently assessed each published study using a MINORS score of ≥ 16 for comparative and ≥ 10 for non-comparative for inclusion. This systematic review followed PRISMA guidelines and was registered with PROSPERO. Synoptic operative templates from published data were assimilated into one "ideal" laparoscopic operative report template following international input from the World Society of Emergency Surgery board. RESULTS: A total of 3567 articles were reviewed. Following MINORS grading 25 studies were selected spanning 14 countries and 4 continents. Twenty-two studies were prospective. A holistic overview of the operative procedure documentation was reported in 6/25 studies and a further 19 papers dealt with selective surgical aspects of LC. A unique synoptic LC operative reporting template was developed and translated into Chinese/Mandarin, French and Arabic. CONCLUSION: This systematic review identified a paucity of publications dealing with operative reporting of LC. The proposed new template may be integrated digitally with hospitals' medical systems and include additional narrative text and audio-visual data. The template may help define new OR (operating room) recording standards and impact on care for patients undergoing LC.

Emergency General Surgery (EGS) was identified as multidisciplinary surgery performed for traumatic and non-traumatic acute conditions during the same admission in the hospital by general emergency surgeons and other specialists. It is the most diffused surgical discipline in the world. To live and grow strong EGS necessitates three fundamental parts: emergency and elective continuous surgical practice, evidence generation through clinical registries and data accrual, and indications and guidelines production: the LIFE TRIAD.

The histamine H(4) receptor is the most recently identified receptor and is considered to play a role in a variety of inflammatory diseases. Histamine levels in the plasma are known to be elevated in animal models of sepsis and in septic patients. The aim of this study was to test the hypothesis that the H(4) receptor may play a significant role in the pathophysiology of sepsis. Polymicrobial sepsis was induced by cecal ligation and puncture in BALB/c mice. Although the H(4) receptor gene was undetectable in normal peripheral key organs, with the exception of the spleen, the expression levels of this gene were highly up-regulated in all those organs of septic mice. In vivo transfection of nuclear factor-kappaB (NF-kappaB) decoy oligodeoxynucleotide, but not of its scrambled form, resulted in a great inhibition of sepsis-induced overexpression of the H(4) receptor gene. In septic mice, marked increases in caspase-3 activation and follicular lymphocyte apoptosis in spleens were strongly suppressed by systemic treatment with synthetic small interfering RNA (siRNA) targeted to the H(4) receptor. This was associated with the up-regulation of a number of antiapoptotic proteins. These antiapoptotic effects of H(4) receptor siRNA treatment were all inhibited by further application of NF-kappaB decoy oligonucleotide. Our results suggest that superinduction of the histamine H(4) receptor gene in peripheral key organs, including the spleen, that is promoted by sepsis is transcriptionally controlled by NF-kappaB, whereas stimulation of this receptor is involved in the development of sepsis-induced splenic apoptosis through counteraction of the antiapoptotic action of NF-kappaB.

This study investigated the therapeutic benefits of neuromuscular electrical stimulation (NMES).C57BL/6 mice were administered lipopolysaccharide (LPS; 20âmg/kg body weight) by intraperitoneal injection and divided into control (C) and NMES groups (nâ=â10-12 each). The latter received NMES to the bilateral gastrocnemius muscle for 1âh at low or high frequency (LFâ=â2âHz and HFâ=â50âHz, respectively) and low or high voltage (LVâ=â10âV and HVâ=â50âV, respectively). In LF-LV and LF-HV groups, NMES was performed twice and the results were compared with those for mice that received one round of NMES. Changes in energy metabolism were measured by indirect calorimetry up to 24âh; survival was evaluated up to 72âh after LPS administration; peroxisome proliferator-activated receptor gamma coactivator (PGC)-1α expression in the liver and gastrocnemius muscle was evaluated by quantitative PCR; and plasma concentration of interleukin (IL)-6 was determined by enzyme-linked immunosorbent assay.Survival was improved only in the LF-LV group with one round of NMES (P < 0.01) and the LF-HV group with two rounds of NMES (P < 0.05). Fatty acid oxidation (FAO) was slightly increased in these two groups, whereas carbohydrate oxidation (CHO) was decreased or not changed. Significant upregulation of PGC-1α in muscle as well as a decrease in plasma IL-6 level were also observed in these two groups (P < 0.05).Thus, NMES exerts therapeutic effects under conditions that induce a mild switch in energy metabolism from glucose to lipid predominant metabolism through PGC-1α upregulation and suppression of inflammation, and may be an effective early intervention even in hemodynamically unstable patients.

Although serum markers such as carcinoembryonic antigen (CEA) and carbohydrate antigen (CA19-9) have been widely used in screening for pancreatic cancer (PC), their sensitivity and specificity are unsatisfactory. Recently, a novel tool of analyzing serum using the short-time Fourier transform (STFT) of free induction decays (FIDs) obtained by 1H-NMR has been introduced. We for the first time evaluated the utility of this technology as a diagnostic tool for PC. Serum was obtained from PC patients before starting any treatments. Samples taken from individuals with benign diseases or donors for liver transplantation were obtained as controls. Serum samples from both groups underwent 1H-NMR and STFT of FIDs. STFT data were analyzed by partial least squares discriminant analysis (PLS-DA) to clarify whether differences were apparent between groups. As a result, PLS-DA score plots indicated that STFT of FIDs enabled effective classification of groups with and without PC. Additionally, in a subgroup of PC, long-term survivors (≥ 2 years) could be discriminated from short-term survivors (< 2 years), regardless of pathologic stage or CEA or CA19-9 levels. In conclusion, STFT of FIDs obtained from 1H-NMR have a potential to be a diagnostic and prognostic tool of PC.

BACKGROUND: There is limited information on the predictive accuracy of commonly used predictors, such as lactate, pH or serum potassium for the survival among out-of-hospital cardiac arrest (OHCA) patients with hypothermia. This study aimed to identify the predictive accuracy of these biomarkers for survival among OHCA patients with hypothermia. METHODS: In this retrospective analysis, we analyzed the data from a multicenter, prospective nationwide registry among OHCA patients transported to emergency departments in Japan (the JAAM-OHCA Registry). We included all adult (≥18 years) OHCA patients with hypothermia (≤32.0 °C) who were registered from June 2014 to December 2017 and whose blood test results on hospital arrival were recorded. We calculated the predictive accuracy of pH, lactate, and potassium for 1-month survival. RESULTS: Of the 34,754 patients in the JAAM-OHCA database, we included 754 patients from 66 hospitals. The 1-month survival was 5.8% (44/754). The areas under the curve of the predictors and 95% confidence interval were as follows: pH 0.829 [0.767-0.877] and lactate 0.843 [0.793-0.882]. On setting the cutoff points of 6.9 in pH and 120 mg/dL (13.3 mmol/L) in lactate, the predictors had a high sensitivity (lactate: 0.91; pH 0.91) and a low negative likelihood ratio (lactate: 0.14; pH 0.13), which are suitable to exclude survival to 1 month. Furthermore, in additional analysis that included only the patients with potassium values available, a cutoff point of 7.0 (mmol/L) for serum potassium had high sensitivity (0.96) and a low negative likelihood ratio (0.09). CONCLUSION: This study indicated the predictive accuracy of serum lactate, pH, and potassium for 1-month survival among adult OHCA patients with hypothermia. These biomarkers may help define a more appropriate resuscitation strategy.

BACKGROUND: We aimed to identify the association of pH value in blood gas assessment with neurological outcome among out-of-hospital cardiac arrest (OHCA) patients treated by extracorporeal cardiopulmonary resuscitation (ECPR). METHODS: We retrospectively analyzed the database of a multicenter prospective observational study on OHCA patients in Osaka prefecture, Japan (CRITICAL study), from July 1, 2012 to December 31, 2016. We included adult OHCA patients treated by ECPR. Patients with OHCA from external causes such as trauma were excluded. We conducted logistic regression analysis to identify the odds ratio (OR) and 95% confidence interval (CI) of the pH value for 1 month favorable neurological outcome adjusted for potential confounders including sex, age, witnessed by bystander, CPR by bystander, pre-hospital initial cardiac rhythm, and cardiac rhythm on hospital arrival. RESULTS: Among the 9822 patients in the database, 260 patients were finally included in the analysis. The three groups were Tertile 1: pH ≥ 7.030, Tertile 2: pH 6.875-7.029, and Tertile 3: pH < 6.875. The adjusted OR of Tertiles 2 and 3 compared with Tertile 1 for 1 month favorable neurological outcome were 0.26 (95% CI 0.10-0.63) and 0.24 (95% CI 0.09-0.61), respectively. CONCLUSIONS: This multi-institutional observational study showed that low pH value (< 7.03) before the implementation of ECPR was associated with 1 month unfavorable neurological outcome among OHCA patients treated with ECPR. It may be helpful to consider the candidate for ECPR.
RESUMO
OBJECTIVE: Japan Coma Scale (JCS) is a grading system used to evaluate disturbed consciousness in prehospital care settings. We aimed to identify the association between the JCS levels at the scene with in-hospital mortality, as well as the discrimination ability for the outcomes. DESIGN: A retrospective cohort study based on the nationwide trauma database in Japan. SETTING: Multicentre cohort study using data from the Japan Trauma Data Bank, which is a nationwide, prospective, observational trauma registry derived from 235 hospitals. PARTICIPANTS: Adult trauma victims transferred directly from the scene of injury to the hospital from January 2004 to December 2017 were eligible for inclusion. PRIMARY AND SECONDARY OUTCOMES: Primary outcome was the association between the JCS levels at the scene with in-hospital mortality. We conducted a multivariate logistic regression analysis to calculate the adjusted ORs of JCS levels with 95% CIs for in-hospital mortality. We also calculated the c-statistics for in-hospital mortality. RESULTS: 164 723 patients were included in the analysis. In a multivariate logistic regression analysis, the corresponding adjusted ORs of JCS levels 2 and 3 referred to level 1 for in-hospital mortality were 4.1 (95% CI 3.8 to 4.4) and 26.0 (95% CI 24.8 to 27.2). The c-statistics of the JCS level for in-hospital mortality was 0.845 (95% CI 0.842 to 0.849). CONCLUSIONS: Data from large multicentre prospective registry revealed strong associations of the JCS level at the scene of injury with in-hospital mortality as well as the good discriminatory performance for this outcome.
