Umbral crítico de administración en pacientes con trauma severo y reanimación endovascular: ¿Un concepto útil? / Critical Administration Threshold in severe trauma patients and endovascular resuscitation: A useful concept?

Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.

Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

Commotio cordis (conmoción cardíaca) en un niño. Reporte de un caso / Commotio cordis (cardiac concussion) in a child. A case report

Commotio cordis o conmoción cardíaca es un síndrome arritmogénico mecano-eléctrico raro y mortal. Es la segunda causa de muerte súbita en atletas jóvenes. Se asocia con una lesión que se produce durante la práctica deportiva, en la que un proyectil impacta a alta velocidad en el precordio y provoca una arritmia que conduce a la muerte inmediata del individuo sin una reanimación cardíaca. En las autopsias, los corazones son estructuralmente sanos. Con el conocimiento de este síndrome y las capacitaciones de reanimación cardiorrespiratoria a la comunidad, las tasas de supervivencia han mejorado. El objetivo de este trabajo es describir un paciente que llegó a nuestro hospital con conmotio cordis y su evolución, enfatizando la importancia de medidas de prevención y capacitación de la población en técnicas de reanimación cardiopulmonar y uso del desfibrilador externo automático para la supervivencia de los pacientes que sufren esta entidad.

Commotio cordis or cardiac concussion is a rare and fatal mechano-electric arrhythmogenic syndrome. It is the second most common cause of sudden cardiac death in young athletes. It is most commonly associated with a sports-related injury, wherein, there is a high-velocity impact between a projectile and the precordium, causing arrhythmia that leads to the immediate death of the individual without cardiac resuscitation. On autopsy, the heart is structurally normal. With increasing awareness of this condition and community training in cardiopulmonary resuscitation, survival rates have been improving. The objective of this study is to describe the case of a patient who arrived at our hospital with commotio cordis and his course, emphasizing the importance of prevention and training of the population in cardiopulmonary resuscitation techniques and the use of the automated external defibrillator for the survival of patients suffering from commotio cordis.

Implementation Status of Palliative Care for Patients Died in Peking Union Medical College Hospital,2019 / 中国医学科学院学报

Objective To reveal the current situation of palliative care for patients who died in Peking Union Medical College Hospital,so as to guide the practice of palliative care for patients in terminal stage. Methods A retrospective study was conducted on patients who died in Peking Union Medical College Hospital from January 1,2019 to December 31,2019.The general clinical data of the patients,whether they received palliative care,and the treatment details including invasive rescue measures,symptom controlling,and psychological,social,and spiritual care status before dying were collected for descriptive analysis. Results A total of 244 inpatients died in 2019,including 135 males and 109 females,with an average age of (65.9±16.4) years (1 day to 105 years).Among the 244 patients,112 (45.9%) died of neoplastic diseases and 132 (54.1%) died of non-neoplastic diseases.Sixty-one (25.0%) patients received palliative care before death,and they were mainly distributed in internal medicine departments such as nephrology (100.0%),gastroenterology (80.0%),and geriatrics (72.7%).Twenty-nine patients received sound palliative care,with all symptoms under control and no invasive treatment before death,and twenty-six patients received psychological,social,and spiritual care.Compared with the patients who were not exposed to the concept of palliative care,the patients who received palliative care showed decreased probabilities of cardiopulmonary resuscitation (0 vs 20.2%;χ2=13.009,P<0.001),tracheal intubation (3.3% vs 48.6%;χ2=38.327,P<0.001),and invasive mechanical ventilation (4.9% vs 47.5%;χ2=33.895,P<0.001) and an increased probability of psychological,social,and spiritual care (54.1% vs 2.4%;χ2=91.486,P<0.001). Conclusion The concept of palliative care has a positive impact on the death of end-stage patients.Palliative care services can increase the probability of end-stage patients receiving psychological,social,and spiritual care and reduce the use of invasive treatment.

Research progress of target temperature management on protective mechanism of cardiac function after cardiac arrest / 中华危重病急救医学

Targeted temperature management (TTM) has been partially applied in patients with restoration of spontaneous circulation (ROSC) after cardiac arrest (CA). In the 2020 American Heart Association (AHA) cardiopulmonary resuscitation (CPR) guidelines, TTM is used as advanced life support after ROSC for the treatment of patients with CPR. TTM has a protective effect on cardiac function after CA, but the specific mechanism of its protective effect on cardiac function remains unclear. In this paper, the basic experimental progress, clinical trial progress and development prospect of TTM on the protective mechanism of cardiac function after CA are reviewed.

Clinical characteristics of in-hospital cardiac arrest in emergency patients in Kashgar area and analysis of influencing factors on success rate of cardiopulmonary resuscitation / 中华危重病急救医学

OBJECTIVE@#To analyze the clinical characteristics of patients with emergency in-hospital cardiac arrest (IHCA) in Kashgar, Xinjiang Uygur Autonomous Region and the factors affecting the success rate of cardiopulmonary resuscitation.@*METHODS@#Retrospectively selected patients who had cardiac arrest and cardiopulmonary resuscitation in the emergency department of the People's Hospital of 6 counties and cities in Kashgar area from January 2019 to January 2022. The clinical data of all patients were collected, including gender, age, major underlying diseases, the beginning and duration of resuscitation, the number of electric defibrillation acute physiology and chronic health evaluation II (APACHE II). According to whether the resuscitation was successful, all patients were divided into successful resuscitation group and failed resuscitation group. The clinical characteristics of the two groups were compared. Then, the influencing factors of the success rate of cardiopulmonary resuscitation in IHCA patients were analyzed by binary Logistic regression.@*RESULTS@#A total of 1 376 patients were enrolled, including 1 117 cases of failed resuscitation and 259 cases of successful resuscitation. The success rate of resuscitation was 18.82%. Compared with the resuscitation failure group, the patients in the successful resuscitation group were younger (age: 49.10±20.99 vs. 58.44±18.32), the resuscitation start time was earlier [resuscitation start time ≤ 5 minutes: 76.45% (198/259) vs. 66.61% (744/1 117)], the proportion of cardiovascular and cerebrovascular diseases was lower [cardiovascular disease: 49.42% (128/259) vs. 58.19% (650/1 117), cerebrovascular disease: 17.37% (45/259) vs. 21.58% (241/1 117)], the number of electric defibrillation was lower [times: 0 (0, 2) vs. 1 (0, 1)], the proportion of endotracheal intubation was more [80.31% (208/259) vs. 55.60% (621/1 117)], APACHE II score was lower (13.75±8.03 vs. 17.90±4.63), and the difference was statistically significant (all P < 0.01). Binary Logistic regression analysis showed that age, start time of resuscitation, ventilation mode and APACHE II score were protective factors affecting the success rate of cardiopulmonary resuscitation in patients with emergency IHCA [age: odds ratio (OR) = 0.982, 95% confidence interval (95%CI) was 0.973-0.991, P < 0.001; resuscitation start time ≤ 5 minutes: OR = 0.629, 95%CI was 0.409-0.966, P = 0.034; tracheal intubation assisted ventilation: OR = 0.243, 95%CI was 0.149-0.397, P < 0.001; low APACHE II score: OR = 0.871, 95%CI was 0.836-0.907, P < 0.001], while underlying diseases (cardiovascular diseases) are a risk factor affecting the success rate of cardiopulmonary resuscitation (OR = 1.190, 95%CI was 1.015-1.395, P = 0.036).@*CONCLUSIONS@#Age, resuscitation start time, ventilation mode, APACHE II score and major underlying diseases (cardiovascular diseases) have a greater impact on the success rate of resuscitation in IHCA patients. The above factors are conducive to improving or formulating more effective rescue strategies for IHCA patients, so as to achieve the purpose of improving the success rate of clinical treatment.

Research progress of extracorporeal cardiopulmonary resuscitation combined with therapeutic hypothermia on brain protection / 中华危重病急救医学

Compared with conventional cardiopulmonary resuscitation (CCPR), extracorporeal cardiopulmonary resuscitation (ECPR) can improve the survival rate of patients with cardiac arrest, and reduce the risk of reperfusion injury. However, it is still difficult to avoid the risk of secondary brain damage. Low temperature management has good neuroprotective potential for ECPR patients, which minimizes brain damage. However, unlike CCPR, ECPR has no clear prognostic indicator. The relationship between ECPR combined with hypothermia management-related treatment measure and neurological prognosis is not clear. This article reviews the effect of ECPR combined with different therapeutic hypothermia on brain protection and provides a reference for the prevention and treatment of neurological injury in patients with ECPR.

Pulse pressure loss after extracorporeal cardiopulmonary resuscitation is an independent predictor of ECMO weaning failure / 中华危重病急救医学

OBJECTIVE@#To analyze the predictors of successful weaning off extracorporeal membrane oxygenation (ECMO) after extracorporeal cardiopulmonary resuscitation (ECPR).@*METHODS@#The clinical data of 56 patients with cardiac arrest who underwent ECPR in Hunan Provincial People's Hospital (the First Affiliated Hospital of Hunan Normal University) from July 2018 to September 2022 were retrospectively analyzed. According to whether ECMO was successfully weaning off, patients were divided into the successful weaning off group and the failed weaning off group. The basic data, duration of conventional cardiopulmonary resuscitation (CCPR, the time from cardiopulmonary resuscitation to ECMO), duration of ECMO, pulse pressure loss, complications, and the use of distal perfusion tube and intra-aortic balloon pump (IABP) were compared between the two groups. Univariate and multivariate Logistic regression analyses were performed to identify the risk factors for weaning failure of ECMO.@*RESULTS@#Twenty-three patients (41.07%) were successfully weaned from ECMO. Compared with the successful weaning off group, patients in the failed weaning off group were older (years old: 46.7±15.6 vs. 37.8±16.8, P < 0.05), higher incidence of pulse pressure loss and ECMO complications [81.8% (27/33) vs. 21.7% (5/23), 84.8% (28/33) vs. 39.1% (9/23), both P < 0.01], and longer CCPR time (minutes: 72.3±19.5 vs. 54.4±24.6, P < 0.01), shorter duration of ECMO support (hours: 87.3±81.1 vs. 147.7±50.8, P < 0.01), and worse improvement in arterial blood pH and lactic acid (Lac) levels after ECPR support [pH: 7.1±0.1 vs. 7.3±0.1, Lac (mmol/L): 12.6±2.4 vs. 8.9±2.1, both P < 0.01]. There were no significant differences in the utilization rate of distal perfusion tube and IABP between the two groups. Univariate Logistic regression analysis showed that the factors affecting the weaning off ECMO of ECPR patients were pulse pressure loss, ECMO complications, arterial blood pH and Lac after installation [pulse pressure loss: odds ratio (OR) = 3.37, 95% confidence interval (95%CI) was 1.39-8.17, P = 0.007; ECMO complications: OR = 2.88, 95%CI was 1.11-7.45, P = 0.030; pH after installation: OR = 0.01, 95%CI was 0.00-0.16, P = 0.002; Lac after installation: OR = 1.21, 95%CI was 1.06-1.37, P = 0.003]. After adjusting for the effects of age, gender, ECMO complications, arterial blood pH and Lac after installation, and CCPR time, showed that pulse pressure loss was an independent predictor of weaning failure in ECPR patients (OR = 1.27, 95%CI was 1.01-1.61, P = 0.049).@*CONCLUSIONS@#Early loss of pulse pressure after ECPR is an independent predictor of failed weaning off ECMO in ECPR patients. Strengthening hemodynamic monitoring and management after ECPR is very important for the successful weaning off ECMO in ECPR.

OBJECTIVE@#To investigate the protective effect and potential mechanism of tubastatin A (TubA), a specific inhibitor of histone deacetylase 6 (HDAC6), on renal and intestinal injuries after cardiopulmonary resuscitation (CPR) in swine.@*METHODS@#Twenty-five healthy male white swine were divided into Sham group (n = 6), CPR model group (n = 10) and TubA intervention group (n = 9) using a random number table. The porcine model of CPR was reproduced by 9-minute cardiac arrest induced by electrical stimulation via right ventricle followed by 6-minute CPR. The animals in the Sham group only underwent the regular operation including endotracheal intubation, catheterization, and anesthetic monitoring. At 5 minutes after successful resuscitation, a dose of 4.5 mg/kg of TubA was infused via the femoral vein within 1 hour in the TubA intervention group. The same volume of normal saline was infused in the Sham and CPR model groups. Venous samples were collected before modeling and 1, 2, 4, 24 hours after resuscitation, and the levels of serum creatinine (SCr), blood urea nitrogen (BUN), intestinal fatty acid binding protein (I-FABP) and diamine oxidase (DAO) in serum were determined by enzyme-linked immunoadsordent assay (ELISA). At 24 hours after resuscitation, the upper pole of left kidney and terminal ileum were harvested to detect cell apoptosis by TdT-mediated dUTP-biotin nick end labeling (TUNEL), and the expression levels of receptor-interacting protein 3 (RIP3) and mixed lineage kinase domain-like protein (MLKL) were detected by Western blotting.@*RESULTS@#After resuscitation, renal dysfunction and intestinal mucous injury were observed in the CPR model and TubA intervention groups when compared with the Sham group, which was indicated by significantly increased levels of SCr, BUN, I-FABP and DAO in serum. However, the serum levels of SCr and DAO starting 1 hour after resuscitation, the serum levels of BUN starting 2 hours after resuscitation, and the serum levels of I-FABP starting 4 hours after resuscitation were significantly decreased in the TubA intervention group when compared with the CPR model group [1-hour SCr (μmol/L): 87±6 vs. 122±7, 1-hour DAO (kU/L): 8.1±1.2 vs. 10.3±0.8, 2-hour BUN (mmol/L): 12.3±1.2 vs. 14.7±1.3, 4-hour I-FABP (ng/L): 661±39 vs. 751±38, all P < 0.05]. The detection of tissue samples indicated that cell apoptosis and necroptosis in the kidney and intestine at 24 hours after resuscitation were significantly greater in the CPR model and TubA intervention groups when compared with the Sham group, which were indicated by significantly increased apoptotic index and markedly elevated expression levels of RIP3 and MLKL. Nevertheless, compared with the CPR model group, renal and intestinal apoptotic indexes at 24 hours after resuscitation in the TubA intervention group were significantly decreased [renal apoptosis index: (21.4±4.6)% vs. (55.2±9.5)%, intestinal apoptosis index: (21.3±4.5)% vs. (50.9±7.0)%, both P < 0.05], and the expression levels of RIP3 and MLKL were significantly reduced [renal tissue: RIP3 protein (RIP3/GAPDH) was 1.11±0.07 vs. 1.39±0.17, MLKL protein (MLKL/GAPDH) was 1.20±0.14 vs. 1.51±0.26; intestinal tissue: RIP3 protein (RIP3/GAPDH) was 1.24±0.18 vs. 1.69±0.28, MLKL protein (MLKL/GAPDH) was 1.38±0.15 vs. 1.80±0.26, all P < 0.05].@*CONCLUSIONS@#TubA has the protective effect on alleviating post-resuscitation renal dysfunction and intestinal mucous injury, and its mechanism may be related to inhibition of cell apoptosis and necroptosis.

Alda-1 alleviates brain injury after cardiopulmonary resuscitation by regulating acyl-CoA synthetase long-chain family member 4/glutathione peroxidase 4 pathway-mediated ferroptosis in swine / 中华危重病急救医学

OBJECTIVE@#To investigate whether the acetaldehyde dehydrogenase 2 specific activator, Alda-1, can alleviate brain injury after cardiopulmonary resuscitation (CPR) by inhibiting cell ferroptosis mediated by acyl-CoA synthetase long-chain family member 4/glutathione peroxidase 4 (ACSL4/GPx4) pathway in swine.@*METHODS@#Twenty-two conventional healthy male white swine were divided into Sham group (n = 6), CPR model group (n = 8), and Alda-1 intervention group (CPR+Alda-1 group, n = 8) using a random number table. The swine model of CPR was reproduced by 8 minutes of cardiac arrest induced by ventricular fibrillation through electrical stimulation in the right ventricle followed by 8 minutes of CPR. The Sham group only experienced general preparation. A dose of 0.88 mg/kg of Alda-1 was intravenously injected at 5 minutes after resuscitation in the CPR+Alda-1 group. The same volume of saline was infused in the Sham and CPR model groups. Blood samples were collected from the femoral vein before modeling and 1, 2, 4, 24 hours after resuscitation, and the serum levels of neuron specific enolase (NSE) and S100 β protein were determined by enzyme-linked immunosorbent assay (ELISA). At 24 hours after resuscitation, the status of neurologic function was evaluated by neurological deficit score (NDS). Thereafter, the animals were sacrificed, and brain cortex was harvested to measure iron deposition by Prussian blue staining, malondialdehyde (MDA) and glutathione (GSH) contents by colorimetry, and ACSL4 and GPx4 protein expressions by Western blotting.@*RESULTS@#Compared with the Sham group, the serum levels of NSE and S100β after resuscitation were gradually increased over time, and the NDS score was significantly increased, brain cortical iron deposition and MDA content were significantly increased, GSH content and GPx4 protein expression in brain cortical were significantly decreased, and ACSL4 protein expression was significantly increased at 24 hours after resuscitation in the CPR model and CPR+Alda-1 groups, which indicated that cell ferroptosis occurred in the brain cortex, and the ACSL4/GPx4 pathway participated in this process of cell ferroptosis. Compared with the CPR model group, the serum levels of NSE and S100 β starting 2 hours after resuscitation were significantly decreased in the CPR+Alda-1 group [NSE (μg/L): 24.1±2.4 vs. 28.2±2.1, S100 β (ng/L): 2 279±169 vs. 2 620±241, both P < 0.05]; at 24 hours after resuscitation, the NDS score and brain cortical iron deposition and MDA content were significantly decreased [NDS score: 120±44 vs. 207±68, iron deposition: (2.61±0.36)% vs. (6.31±1.66)%, MDA (μmol/g): 2.93±0.30 vs. 3.68±0.29, all P < 0.05], brain cortical GSH content and GPx4 expression in brain cortical was significantly increased [GSH (mg/g): 4.59±0.63 vs. 3.51±0.56, GPx4 protein (GPx4/GAPDH): 0.54±0.14 vs. 0.21±0.08, both P < 0.05], and ACSL4 protein expression was significantly decreased (ACSL4/GAPDH: 0.46±0.08 vs. 0.85±0.13, P < 0.05), which indicated that Alda-1 might alleviate brain cortical cell ferroptosis through regulating ACSL4/GPx4 pathway.@*CONCLUSIONS@#Alda-1 can reduce brain injury after CPR in swine, which may be related to the inhibition of ACSL4/GPx4 pathway mediated ferroptosis.

Effects of mechanical cardiopulmonary resuscitation during vertical spatial pre-hospital transport in patients with cardiac arrest: a historical cohort study / 中华危重病急救医学

OBJECTIVE@#To analyze the effect of mechanical cardiopulmonary resuscitation (CPR) on patients with cardiac arrest with the vertical spatial pre-hospital emergency transport.@*METHODS@#A retrospective cohort study was conducted. The clinical data of 102 patients with out-of-hospital cardiac arrest (OHCA) who were transferred to the emergency medicine department of Huzhou Central Hospital from the Huzhou Emergency Center from July 2019 to June 2021 were collected. Among them, the patients who performed artificial chest compression during the pre-hospital transfer from July 2019 to June 2020 served as the control group, and the patients who performed artificial-mechanical chest compression (implemented artificial chest compression first, and implemented mechanical chest compression immediately after the mechanical chest compression device was ready) during pre-hospital transfer from July 2020 to June 2021 served as the observation group. The clinical data of patients of the two groups were collected, including basic data (gender, age, etc.), pre-hospital emergency process evaluation indicators [chest compression fraction (CCF), total CPR pause time, pre-hospital transfer time, vertical spatial transfer time], and in-hospital advanced resuscitation effect evaluation indicators [initial end-expiratory partial pressure of carbon dioxide (PETCO2), rate of restoration of spontaneous circulation (ROSC), time of ROSC].@*RESULTS@#Finally, a total of 84 patients were enrolled, including 46 patients in the control group and 38 in the observation group. There was no significant difference in gender, age, whether to accept bystander resuscitation or not, initial cardiac rhythm, time-consuming pre-hospital emergency response, floor location at the time of onset, estimated vertical height, and whether there was any vertical transfer elevator/escalator, etc. between the two groups. In the evaluation of the pre-hospital emergency process, the CCF during the pre-hospital emergency treatment of patients in the observation group was significantly higher than that in the control group [69.05% (67.35%, 71.73%) vs. 61.88% (58.18%, 65.04%), P < 0.01], the total pause time of CPR was significantly shorter than that in the control group [s: 266 (214, 307) vs. 332 (257, 374), P < 0.05]. However, there was no significant difference in the pre-hospital transfer time and vertical spatial transfer time between the observation group and the control group [pre-hospital transfer time (minutes): 14.50 (12.00, 16.75) vs. 14.00 (11.00, 16.00), vertical spatial transfer time (s): 32.15±17.43 vs. 27.96±18.67, both P > 0.05]. It indicated that mechanical CPR could improve the CPR quality in the process of pre-hospital first aid, and did not affect the transfer of patients by pre-hospital emergency medical personnel. In the evaluation of the in-hospital advanced resuscitation effect, the initial PETCO2 of the patients in the observation group was significantly higher than that of the patients in the control group [mmHg (1 mmHg ≈ 0.133 kPa): 15.00 (13.25, 16.00) vs. 12.00 (11.00, 13.00), P < 0.01], the time of ROSC was significantly shorter than that in the control group (minutes: 11.00±3.25 vs. 16.64±2.54, P < 0.01), and the rate of ROSC was slightly higher than that in the control group (31.58% vs. 23.91%, P > 0.05). It indicated that continuous mechanical compression during pre-hospital transfer helped to ensure continuous high-quality CPR.@*CONCLUSIONS@#Mechanical chest compression can improve the quality of continuous CPR during the pre-hospital transfer of patients with OHCA, and improve the initial resuscitation outcome of patients.
