Long-Term Mortality of Children with Congenital Heart Disease Admitted to the Departmental University Hospital of Borgou/Alibori from 2011 to 2022

Background: Congenital heart disease is a public health issue due to its incidence and mortality rate. The aim of this study was to investigate the long-term mortality of children with congenital heart disease admitted to the Departmental University Hospital of Borgou/Alibori (CHUD-B/A) from 2011 to 2022. Methods: This descriptive longitudinal study with analytical aims covered 11 years (April 1, 2011 to December 31, 2022). It consisted of a review of the records of children under 15 years of age with echocardiographically confirmed congenital heart disease. This was followed by an interview with the parents to assess the children’s current condition. Data were entered using Kobocollect software and analyzed using R Studio 4.2.2. software. Results: A total of 143 complete files were retained. The median age at diagnosis was 14 months (IIQ: Q1 = 4;Q3 = 60) with a range of 2 days and 175 months, and the sex-ratio (M/F) was 0.96. Left-to-right shunts were the most frequent cardiopathy group (62.9%). Only 35 children (24.5%) benefited from restorative treatment. The mortality rate was 31.5%. Median survival under the maximum bias assumption was 114 months and 216 months under the assumption of minimum bias. Survival was significantly better in children with right-to-left shunts (p = 0.0049) under the assumption of minimum bias. The death risk factors were: age at diagnosis less than 12 months (aHR = 7.58;95% CI = 3.36 - 17.24;p Conclusion: The long-term mortality of congenital heart disease is high and favoured by the absence of restorative treatment. Local correction of congenital heart disease and medical follow-up will help to reduce this mortality.

Impact of Atrial Septal Defect Closure on Mortality in Older Patients

Background:Atrial septal defect(ASD)is a common form of adult congenital heart disease that can lead to long-term adverse outcomes if left untreated.Early closure of ASD has been associated with excellent outcomes and lower complication rates.However,there is limited evidence regarding the prognosis of ASD closure in older adults.This study aims to evaluate the mortality rates in older ASD patients with and without closure.Methods:A retrospective cohort study was conducted on patients aged 40 years or older with ASD between 2001 and 2017.Patients were followed up to assess all-cause mortality.Univariable and multivariable analyses were performed to identify the predictors of mortality.A p-value of<0.05 was considered statistically significant.Results:The cohort consisted of 450 patients(mean age 56.6±10.4 years,77.3%female),with 66%aged between 40 and 60 years,and 34%over 60 years.Within the cohort,299 underwent ASD closure(201 with transcatheter and 98 with surgical closure).During the median follow-up duration of 7.9 years,51 patients died.The unadjusted cumulative 10-year rate of mortality was 3%in patients with ASD closure,and 28%in patients without ASD closure(log-rank p<0.001).Multivariable analysis revealed that age(hazard ratio[HR]1.04,95%confidence interval[CI]1.006–1.06,p=0.01),NYHA class(HR 2.75,95%CI 1.63–4.62,p<0.001),blood urea nitrogen(BUN)(HR 1.07,95%CI 1.03–1.12,p<0.001),right ventricular systolic pressure(RVSP)(HR 1.07,95%CI 1.003–1.04,p=0.01),and lack of ASD closure(HR 15.12,95%CI 5.63–40.59,p<0.001)were independently associated with mortality.Conclusion:ASD closure demonstrated favorable outcomes in older patients.Age,NYHA class,BUN,RVSP,and lack of ASD closure were identified as independent factors linked to mortality in this population.

Surgical Management of Perforated Colon Tumours in Yaoundé: A Multicentre Retrospective Review of 30-Day Postoperative Outcome

Introduction: Colon cancer is often diagnosed late in our context and there is a high prevalence of complicated forms, this including perforation. The optimal surgical treatment remains controversial. The aim of this study was to improve the short-term postoperative outcomes of patients operated upon for perforated colon cancer, by identifying factors associated with complications occurring within 30 days after surgery. Patients and methods: We carried out an analytical observational study, with a retrospective collection of data from the files of patients operated upon for an in situ tumoral colon perforation. This was done in four referral hospitals in the city of Yaoundé. The period was from the 1st of January, 2012 to the 31st of December, 2021. Cox regression identified the factors associated with postoperative morbidity and mortality. Results: We collected files of 46 patients. The mean age was 54.7 ± 19.9 years with a sex ratio of 1.4. The clinical presentation on admission was dominated by the presence of signs of peritoneal irritation (91.3%) and bowel obstruction (28.3%). The diagnosis was made preoperatively in 16 cases (34.8%). The surgical procedures consisted of colectomy with anastomosis in 28 cases (60.9%) and without anastomosis in 14 cases (30.4%). Postoperative morbidity was 60.9% dominated by surgical site infection (37%). Postoperative mortality was 39.1%. The existence of generalized peritonitis was associated with the occurrence of postoperative complications (p = 0.019). The main factors associated with postoperative mortality were resection with primary anastomosis (p = 0.027), enterocutaneous fistula (p = 0.005). Conclusion: Colic resection with primary anastomosis or ideal colectomy is associated with an increased risk of mortality and should therefore not be performed in this setting.

Postoperative mortality and morbidity after D2 lymphadenectomy for gastric cancer:A retrospective cohort study

BACKGROUND Surgery for gastric cancer is a complex procedure and lymphadenectomy is often mandatory.Postoperative mortality and morbidity after curative gastric cancer surgery is not insignificant.AIM To evaluate the factors determining mortality and morbidity in a population of patients undergoing R0 resection and D2 lymphadenectomy for gastric cancer.METHODS A retrospective analysis of clinical data and pathological characteristics(age,sex,primary site of the tumor,Lauren histotype,number of positive lymph nodes resected,number of negative lymph nodes resected,and depth of invasion as defined by the standard nomenclature)was conducted in patients with gastric cancer.For each patient we calculated the Kattan’s score.We arbitrarily divided the study population of patients into two groups based on the nomogram score(<100 points or≥100 points).Prespecified subgroups in these analyses were defined according to age(≤65 years or>65 years),and number of lymph nodes retrieved(≤35 lymph nodes or>35 lymph nodes).Uni-and multivariate analysis of clinical and pathological findings were performed to identify the factors affecting postoperative mortality and morbidity.RESULTS One-hundred and eighty-six patients underwent a curative R0 resection with D2 lymphadenectomy.Perioperative mortality rate was 3.8%(7 patients);a higher mortality rate was observed in patients aged>65 years(P=0.002)and in N+patients(P=0.04).Following univariate analysis,mortality was related to a Kattan’s score≥100 points(P=0.04)and the presence of advanced gastric cancer(P=0.03).Morbidity rate was 21.0%(40 patients).Surgical complications were observed in 17 patients(9.1%).A higher incidence of morbidity was observed in patients where more than 35 lymph nodes were harvested(P=0.0005).CONCLUSION Mortality and morbidity rate are higher in N+and advanced gastric cancer patients.The removal of more than 35 lymph nodes does not lead to an increase in mortality.

Risk factors for mortality in postoperative peritonitis in critically ill patients

AIM To identify the risk factors for mortality in intensive care patients with postoperative peritonitis(POP).METHODS This was a retrospective analysis using a prospective database that includes all patients hospitalized in a surgical intensive care unit for POP from September 2006 to August 2011. The data collected included demographics, comorbidities, postoperative severity parameters, bacteriological findings, adequacy of antimicrobial therapy and surgical treatments. Adequate source control was defined based on a midline laparotomy, infection source control and intraoperative peritoneal lavage. The number of reoperations needed was also recorded.RESULTS A total of 201 patients were included. The overall mortality rate was 31%. Three independent risk factors for mortality were identified: The Simplified Acute Physiological Ⅱ Score(OR = 1.03; 95%CI: 1.02-1.05, P < 0.001), postoperative medical complications(OR = 6.02; 95%CI: 1.95-18.55, P < 0.001) and the number of reoperations(OR = 2.45; 95%CI: 1.16-5.17, P = 0.015). Surgery was considered as optimal in 69% of the cases, but without any significant effect on mortality. CONCLUSION The results from the large cohort in this study emphasize the role of the initial postoperative severity parameters inthe prognosis of POP. No predefined criteria for optimal surgery were significantly associated with increased mortality, although the number of reoperations appeared as an independent risk factor of mortality.

Liver resection and metabolic disorders: An undescribed mechanism leading to postoperative mortality

AIM: To investigate the mechanism leading to perioperative mortality in patients undergoing major liver resection and presenting with metabolic disorders.METHODS: The link between Metabolic Syndrome and non-alcoholic fatty liver disease is currently demonstrated. Various metabolic disorders and the Metabolic Syndrome(the association of ≥ 3 metabolic disorders) have been recently described as a risk factor of perioperative mortality in major liver resection. Patients who passed away during perioperative course of major liver resection and presenting with the association of ≥ 2 metabolic disorders without any other known cause of liver disorders were reviewed.RESULTS: From January 2001 to May 2010 in a tertiary centre, ten patients presenting with ≥ 2 metabolic disorders without any other known cause of liver disorders died during perioperative course of major liver resection. The same four-consecutive-steps sequence of events occurred, including jaundice. The analysis of this series suggested a rapidly deteriorating congestive liver resulting in an increased portal hypertension leading to hepatorenal syndrome and lately to multiorgan failure(mimicking septic collapse) as the mechanism leading to exitus. The acute portal hypertension is mainly related to the surgical procedure. The chronic portal hypertension is indeterminate. Patients with ≥ 2 metabolic disorders should be considered as potentially presenting with portal hypertension possibly evolving towards hepatorenal syndrome; thus, they should be considered as having a high perioperative risk and should be carefully evaluated before undergoing major liver resection.CONCLUSION: As fibrosis was not present or marginal in liver specimens, the real cause of portal hypertension in patients with multiple metabolic disorders should be investigated with further studies.

Predictive value of SinoSCORE on in-hospital mortality and postoperative complications after coronary artery bypass surgery

Objective To evaluate the performance of the Sino System for Coronary Operative Risk Evaluation (SinoSCORE) on in hospital mortality and postoperative complications in patients undergoing coronary artery bypass grafting (CABG) in a single heart center. Methods From January 2007 to December 2008,clinical information of 201 consecutive patients undergoing isolated CABG in our hospital was collected. The SinoSCORE was used to

Early Postoperative Deaths in the Surgical Intensive Care Unit of CHU-Kara

Aim: Review of early postoperative deaths in the surgical intensive care unit at CHU-Kara. Introduction: Surgery, one of the means of treatment of diseases, also presents risks for the patient, including early postoperative death linked to numerous risk factors. Methodology: This was a retrospective descriptive study conducted on the records of patients who died within 48 hours after surgery from November 1, 2019 to April 30, 2021. The study was conducted in the surgical intensive care unit and in the operating room. Results: Thirty-two early postoperative deaths or 2.22% out of 1442 operated with 30 deaths retained for the study. Male gender predominated (70%). The average age was 31.22 years. Farmers were more concerned (66.67%). The time to surgery was 1.6 days. ASA1 patients (40%) predominated followed by ASA IV (30%). 80% of patients were operated on as an emergency. Digestive pathologies 80% were more represented. General anaesthesia 86.66% was more practiced associating Propofol, Fentanyl, Ketamine and Atropine more frequently. The average duration of the procedures was 132.5 minutes. Intraoperative complications were associated with cardiac arrest and hemorrhage (33.34%). ASA class higher than 2, dirty surgery (46.67%), and delayed recovery (13.34%) were the incriminating risk factors. Death by hemodynamic shock and respiratory distress were the main causes 26.66%. Conclusion: Early postoperative mortality was high and involved all ages. Anesthesia and surgery, the low level of qualification of the intraoperative actors, the lesser intraoperative security;the association of anesthetic effects, the complexity of intraoperative lesions led to the increase of mortality. The combination of two or more factors was pejorative for the deaths.

Elderly patients had more severe postoperative complications after pancreatic resection:A retrospective analysis of 727 patients

AIM To examine the impact of aging on the short-term outcomes following pancreatic resection(PR) in elderly patients.METHODS A retrospective cohort study using prospectively collected data was conducted at the China National Cancer Center. Consecutive patients who underwent PR from January 2004 to December 2015 were identifiedand included. ‘Elderly patient' was defined as ones age 65 and above. Comorbidities, clinicopathology, perioperative variables, and postoperative morbidity and mortality were compared between the elderly and young patients. Univariate and multivariate analyses were performed using the Cox proportional hazard model for severe postoperative complications(grades Ⅲb-Ⅴ).RESULTS A total of 454(63.4%) patients were < 65-yearsold and 273(36.6%) patients were ≥ 65-yearsold, respectively. Compared to patients < 65-yearsold, elderly patients had worse American Society of Anesthesiologists scores(P = 0.007) and more comorbidities(62.6% vs 32.4%, P < 0.001). Elderly patients had more severe postoperative complications(16.8% vs 9.0%, P = 0.002) and higher postoperative mortality rates(5.5% vs 0.9%, P < 0.001). In the multivariate Cox proportional hazards model for severe postoperative complications, age ≥ 65 years [hazard ratio(HR) = 1.63; 95% confidence interval(CI): 1.18-6.30], body mass index ≥ 24 kg/m^2(HR = 1.20, 95%CI: 1.07-5.89), pancreaticoduodenectomy(HR = 4.86, 95%CI: 1.20-8.31) and length of operation ≥ 241 min(HR = 2.97; 95%CI: 1.04-6.14) were significant(P = 0.010, P = 0.041, P = 0.017 and P = 0.012, respectively).CONCLUSION We found that aging is an independent risk factor for severe postoperative complications after PR. Our results might contribute to more informed decision-making for elderly patients.

Surgical mortality in patients with malignant obstructive jaundice: a multivariate discriminant analysis

OBJECTIVE: To estimate the operative mortality in patients with malignant obstructive jaundice. METHODS: Twelve risk factors were analyzed using multivariate discriminant analysis in 90 patients who had been operated on. RESULTS: Operative mortality was significantly related to the following factors: age, duration of jaundice, packed RBC volume, white blood cell count and concentration of blood urine nitrogen; it was not significantly related to diseases and types of operation. The following formula was obtained: packed RBC volume×0.09954-age×0. 04018-blood urine nitrogen×0. 23693-duration of jaundice× 2. 07388-WBC count×0. 21118+5. 26593. With this formula, an operative mortality of 77. 8% was predicted. CONCLUSION: With a positive value from the formula, the patient should be operated on; otherwise non-operative treatment is advocated.

Modified physiological and operative score for the enumeration of mortality and morbidity risk assessment model in general surgery

AIM: To establish a scoring system for predicting the incidence of postoperative complications and mortality in general surgery based on the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM), and to evaluate its efficacy. METHODS: Eighty-four patients with postoperative complications or death and 172 patients without postoperative complications, who underwent surgery in our department during the previous 2 years, were retrospectively analyzed by logistic regression. Fifteen indexes were investigated including age, cardiovascular function, respiratory function, blood test results, endocrine function, central nervous system function, hepatic function, renal function, nutritional status, extent of operative trauma, and course of anesthesia. Modified POSSUM (M-POSSUM) was developed using significant risk factors with its efficacy evaluated. RESULTS: The significant risk factors were found to be age, cardiovascular function, respiratory function, hepatic function, renal function, blood test results, endocrine function, nutritional status, duration of operation, intraoperative blood loss, and course of anesthesia. These factors were all included in the scoring system. There were significant differences in the scores between the patients with and without postoperative complications, between the patients died and survived with complications, and between the patients died and survived without complications. The receiver operating characteristic curves showed that the M-POSSUM could accurately predict postoperative complications and mortality.CONCLUSION: M-POSSUM correlates well with postoperative complications and mortality, and is more accurate than POSSUM.

A Review of Hip Fracture Mortality—Why and How Does Such a Large Proportion of These Elderly Patients Die?

As the number of aged patients presenting with hip fractures continues to rise [1], the substantial mortality associated with this pathology must continue to be an area of scrutiny and improvement. While some dismiss the high mortality as an inevitable consequence of the comorbidities inherent in the original injury and the patient population, data suggest that at 2 years post-hip fracture, survivors’ risks have regressed significantly and in fact, return to the same mortality risk as the non-fracture population [2]. This indicates that the risk of death is largely created specifically by the hip fracture and its treatment per se rather than the comorbidities of the hip fracture population, and offers scope for the potential reduction of these causes of death if we can identify and manage them appropriately. At a time when the incidence of hip fracture worldwide is on a steady rise, this review considers why and how these older patients die, and whether our developing guidelines and continuing research is adequately addressing these causes of death.

Post-Operative Peritonitis: Diagnostic Problems, Morbidity and Mortality in Developing Countries

Goal: To study the diagnostic difficulties and post-operative morbidity and mortality of peritonitis. Patients and Methods: Retrospective study about the records of adult patients operated on between 1999 and 2013 whose diagnosis of post-operative peritonitis was made. Results: We achieved 23,573 lanterns and recorded 148 cases of postoperative peritonitis or 0.62%. The medium age was 37.1 ± 17.7 years and the sex ratio was 1.2. The delay between the initial intervention and reoperation was less than 5 days. Factors occurrence of postoperative peritonitis were those related to the initial surgery: septic context 70.8%, emergency surgery 81.1% under the seat mesocolic 25% and 20.3% initial surgical technique. The diagnosis was made preoperatively in 62.2% (n = 92). Ultrasound has found an effusion in 29.7% (n = 44). Cytobactériologic review identified germs in 85.1% (n = 126) and sterile in 12.9% of patients (n = 22). The most frequent etiologies were: 22.9% anastigmatic leak (n = 34), the phoenix abscess in 17.6% (n = 26), iatrogenic perforation 13.5% (n = 20) and digestive fistula 25% (n = 37). Other causes were the stoical necrosis 12.2% (n = 18) and evisceration 8.8% (n = 13). We performed a digestive stoma in 61% (n = 89), a closure of the abdomen bolsters in 8.8% (n = 13), a suture in iatrogenic perforation in 13.5% (n = 20) and washing with drainage in patients with phoenix abscess in 17.6% (n = 26). Morbidity was 22.3% and 53.4% mortality. Conclusion: The diagnosis of post-operative peritonitis is difficult in a developing country. Morbidity and mortality is high. Improved diagnostic tools are needed.

The Association between Preoperative Plasma C-Reactive Protein (CRP) Level and Postoperative Adult Heart Surgery Outcome

Introduction: Careful history and physical examinations are the best ways for preoperative evaluation. Currently, we are recommended to rely on doing them rather than unnecessary and costly laboratory tests for confirmation or diagnosis of disease. The aim of study is the survey of CRP level association to decide further evaluation and expert consultation, newly diagnosed problems and possible effect on postoperative mortality and morbidity. Methods and Materials: In a descriptive retrospective study, hospital documentation of 620 patients older than 18 years undergone heart surgery in Tabriz Shahid Madani hospital was evaluated. Addition to plasma CRP level, patient’s demographic information, type of surgery, preoperative significant tests, delay time in surgery start time after anesthesiology visit, cause of requested specialty consultation and treatment recommendation, postoperative complications and mortality rate were recorded and analyzed. Patients were classified according to preoperative plasma CRP level to five groups as negative, +1, +2, +3 and not measured (i.e. they considered as normal (0 - 5 mg/l), mildly (5 - 40 mg/l), moderately (40 - 200 mg/L) or severely increased (>200 mg/l) groups). Results: Of 620 patients, 402 were male and 218 were female. There was not statistically significant correlation among demographic variables (gender, age, weight, and height), heart disease diagnosis and the type of surgery in five groups. In 79 individuals, they were done specialty consultations that most common of them were neurology consultation because of impaired renal laboratory tests. Only 2 cases were due to high CRP level. In any of cases, this preoperative consultation didn’t result from new disease cases. CRP plasma level hadn’t association with preoperative red blood cell sedimentation level. Prevalence of preoperative acute myocardium infarction was higher in patients with high CRP level. In group +1, delay time was lower than other groups. The most common causes were cardiac causes. There wasn’t statistically significant correlation between CRP level and different postoperative complications. There wasn’t significant association between ICU stay time and postoperative hospital stay time and plasma high CRP level. Conclusion: Probably, plasma CRP level increases before surgery in acute myocardial infarction and results in high mortality rate. It seems that routine measurement of CRP in candidates for heart operation is beneficial for mortality rate prediction, so its increasing level can’t help to diagnosis newly cases and it isn’t prudent to consult with specialist.

Long-Term Outcomes after Coronary Artery Bypass Grafting with Risk Stratification

Background: Risk stratification of long-term outcomes for patients undergoing Coronary artery bypass grafting has enormous potential clinical importance. Aim: To develop risk stratification models for predicting long-term outcomes following coronary artery bypass graft (CABG) surgery. Methods: We retrospectively revised the electronic medical records of 2330 patients who underwent adult Cardiac surgery between August 2016 and December 2022 at Madinah Cardiac Center, Saudi Arabia. Three hundred patients fulfilled the eligibility criteria of CABG operations with a complete follow-up period of at least 24 months, and data reporting. The collected data included patient demographics, comorbidities, laboratory data, pharmacotherapy, echocardiographic parameters, procedural details, postoperative data, in-hospital outcomes, and follow-up data. Our follow-up was depending on the clinical status (NYHA class), chest pain recurrence, medication dependence and echo follow-up. A univariate analysis was performed between each patient risk factor and the long-term outcome to determine the preoperative, operative, and postoperative factors significantly associated with each long-term outcome. Then a multivariable logistic regression analysis was performed with a stepwise, forward selection procedure. Significant (p < 0.05) risk factors were identified and were used as candidate variables in the development of a multivariable risk prediction model. Results: The incidence of all-cause mortality during hospital admission or follow-up period was 2.3%. Other long-term outcomes included all-cause recurrent hospitalization (9.8%), recurrent chest pain (2.4%), and the need for revascularization by using a stent in 5 (3.0%) patients. Thirteen (4.4%) patients suffered heart failure and they were on the maximum anti-failure medications. The model for predicting all-cause mortality included the preoperative EF ≤ 35% (AOR: 30.757, p = 0.061), the bypass time (AOR: 1.029, p = 0.003), and the duration of ventilation following the operation (AOR: 1.237, p = 0.021). The model for risk stratification of recurrent hospitalization comprised the preoperative EF ≤ 35% (AOR: 6.198, p p = 0.023), low postoperative cardiac output (AOR: 3.622, p = 0.007), and the development of postoperative atrial fibrillation (AOR: 2.787, p = 0.038). Low postoperative cardiac output was the only predictor that significantly contributed to recurrent chest pain (AOR: 11.66, p = 0.004). Finally, the model consisted of low postoperative cardiac output (AOR: 5.976, p < 0.001) and postoperative ventricular fibrillation (AOR: 4.216, p = 0.019) was significantly associated with an increased likelihood of the future need for revascularization using a stent. Conclusions: A risk prediction model was developed in a Saudi cohort for predicting all-cause mortality risk during both hospital admission and the follow-up period of at least 24 months after isolated CABG surgery. A set of models were also developed for predicting long-term risks of all-cause recurrent hospitalization, recurrent chest pain, heart failure, and the need for revascularization by using stents.

非工作日手术对患者住院期间死亡及重要器官功能衰竭的影响

目的探究非工作日手术对患者住院期间死亡及术后重要器官功能衰竭的影响。方法收集2021年华西医院住院时间≥24 h、住院期间接受手术患者病例资料。根据手术结束时间将患者分为两组:工作日组和非工作日组(包括法定节假日)。采取倾向得分匹配法比较两组患者住院期间死亡率、术后重要器官功能衰竭发生率等方面的差异。结果研究共纳入74664例病例,其中工作日组64433例,非工作日组10201例。匹配前,纳入全部可干预及不可干预因素的二元logistics回归分析显示,非工作日手术是影响患者住院期间死亡率及术后重要器官功能衰竭发生率的独立危险因素(OR=1.16,95%CI:1.00~1.35,P=0.04;OR=1.23,95%CI:1.07~1.42,P<0.01)。此外,是否为微创手术及出血量也是影响住院期间死亡率及术后重要器官功能衰竭的独立危险因素(P<0.05)。匹配后,非工作日组住院期间死亡率(2.6%vs 1.7%)与术后重要器官功能衰竭发生率(3.5%vs 2.3%)显著高于工作日组(P<0.01);同时,非工作日手术的手术时间(1.5 h vs 1.3 h)、出血量超过500 ml患者比例(2.5%vs 1.9%)亦高于工作日组(P<0.05),采用微创术式的手术比例(58.6%vs 60.6%)低于工作日组。结论非工作日手术患者术后死亡率、术后重要器官功能衰竭率更高。若减少非工作日手术时长与术中出血量,增加微创手术比例,可能会降低非工作日手术患者住院期间死亡率及术后重要器官衰竭发生率。

腰大肌-腰椎指数与老年髋部骨折术后并发症风险的关系

目的评估腰大肌-腰椎指数(PLVI)与老年髋部骨折术后并发症风险的关系。方法回顾性分析了2016-03至2020-12在联勤保障部队第943医院接受髋部骨折手术的686例老年患者。采用计算机断层扫描(CT)计算腰大肌横截面积和L4椎体面积,PLVI定义为左右腰肌平均横截面积和L4椎体面积之间的比值。根据男性和女性PLVI中位数将患者分为两组(低PLVI组和高PLVI组)。主要结局为手术后6个月内并发症(包括愈合不良、谵妄、肺炎、尿路感染、深静脉血栓、心力衰竭、呼吸衰竭、脓毒症)。次要研究终点为1年死亡率和总死亡率。结果术后6个月内122例(17.78%)患者出现并发症,这部分患者术前PLVI更低(P<0.05)。与高PLVI组相比,低PLVI组患者愈合不良、谵妄、肺炎的发生率高,同时血清白蛋白(ALB)水平降低,而血清C反应蛋白水平升高(P<0.05)。在多因素Logistic回归分析中,合并慢性肾脏疾病(OR=3.500,95%CI:1.484~8.252)、骨折至手术间隔延迟(OR=1.711,95%CI:1.044~2.804)、术前ALB水平降低(OR=4.922,95%CI:2.633~9.202),以及低PLVI(OR=0.136,95%CI:0.074~0.249)都是影响老年患者髋部骨折手术后并发症(包括愈合不良、谵妄、肺炎)发病风险的独立预测因子(P<0.05)。经Kaplan-Meier曲线分析,低PLVI组患者总死亡率(11.37%,39/343)高于高PLVI组(1.75%,6/343),差异有统计学意义(log rank=24.610,P<0.001)。结论术前PLVI可独立预测老年患者髋部骨折手术后愈合不良、谵妄、肺炎的发生风险及死亡率。

Impact of malnutrition on long-term mortality in critical patients with atrial fibrillation

Background Malnutrition has been shown to be related to adverse clinical outcomes in patients with cardiovascular diseases.However,the association of nutritional state and long-term all-cause mortality in critical patients with atrial fibrillation(AF)remains unknown.Methods Critical patients who complicated with AF in the third edition of the Medical Information Mart in Critical Care(MIMIC-Ⅲ)registry were enrolled into this study.The primary endpoint was long-term all-cause mortality.Patients'nutrition status was tested by 4 screening tools,which included controlling nutritional status(CONUT),prognostic nutritional index(PNI),geriatric nutritional risk index(GNRI)scores and body mass index(BMI).Kaplan-Meier and Cox proportional analyses were used to investigate the association between nutritional state and 4-year all-cause mortality.Results A total of 630 critical patients with AF(72.0±11.2 years,male 36.5%)were included in this study,and the 4-year all-cause mortality rate was42.5%(n=268).It was up to 68.5%patients with malnutrition according to CONUT score.Kaplan-Meier and multivariate Cox proportional regression showed that the moderate to severe malnutrition was independent indicator for long-term mortality based on CONUT score(moderate vs.normal,adjusted hazard ratio[HR]:1.78,95%CI:1.22-2.62;Severe vs.normal adjusted HR:2.18,95%CI:1.52-3.15,respectively].Furthermore,the CONUT score showed the best effect of predicting worsen long-term prognosis among 4 malnutrition screening tools(The Area under cure[AUC]of CONUT vs.PNI vs.GNRI vs.BMI=0.656 vs.0.643 vs.0.617 vs.0.552).Conclusions Malnutrition is a common complication and significantly affects the prognosis of critical patients with AF,and CONUT score is an optimal screening tool to assess the nutritional status and long-term prognosis in these patient.

Long-term outcomes after laparoscopic colectomy

AIM:To evaluate long-term outcomes in a large series of patients who randomly received laparoscopic or open colorectal resection.METHODS:From February 2000 to December 2004,six hundred sixty-two patients with colorectal disease were randomly assigned to laparoscopic(LPS,n = 330) or open(n = 332) colorectal resection.All patients were analyzed on an intention-to-treat basis.Long-term follow-up was carried out every 6 mo by office visits.In 526 cancer patients five-year overall and disease-free survival were evaluated.Median oncologic follow-up was 96 mo.RESULTS:Eight(4.2%) LPS group patients needed conversion to open surgery.Overall long-term morbidity rate was 7.6%(25/330) in the LPS vs 11.1%(37/332) in the open group(P = 0.17).In cancer patients,fiveyear overall survival was 68.6% in the LPS group and 64.0% in the Open group(P = 0.27).Excluding stage Ⅳ patients,five-year local and distant recurrence rates were 32.5% in the LPS group and 36.8% in the Open group(P = 0.36).Further,no difference in recurrence rate was found when patients were stratified according to cancer stage.CONCLUSION:LPS colorectal resection was associated with a slightly lower incidence of long-term complications than open surgery.No difference between groups was found in overall and disease-free survival rates.

Systematic review of long-term Xingnao Kaiqiao needling efficacy in ischemic stroke treatment

OBJeCTIve：To systematically evaluate the long-term effect and safety ofXingnao Kaiqiao nee-dling method in ischemic stroke treatment. DATA ReTRIevAL： We retrieved relevant random and semi-random controlled trials that used theXingnao Kaiqiao needling method to treat ischemic stroke compared with various control treatments such as conventional drugs or other acupuncture therapies. Searched databases included China National Knowledge Infrastructure, Weipu Information Resources System, Wanfang Medical Data System, Chinese Biomedical Literature Database, Cochrane Library, and PubMed, from May 2006 to July 2014. SeLeCTION CRITeRIA： Two authors independently conducted literature screening, quality evaluation, and data extraction. The quality of articles was evaluated according to the Cochrane Reviewers’ Handbook 5.1, and the study was carried out using Cochrane system assessment methods. RevMan 5.2 was used for meta-analysis of the included studies. MAIN OUTCOMe MeASUReS： Mortality rate, recurrence rate, and disability rate were observed. ReSULTS：Nine randomized and semi-randomized controlled trials treating 931 cases of ischemic stroke were included in this review. Meta-analysis results showed that there were no sig-niifcant differences in mortality reduction （risk ratio （RR） = 0.58, 95% conifdence interval （CI）： 0.17–1.93,Z = 0.89,P = 0.37） or recurrence rate （RR = 0.55, 95%CI： 0.18–1.70,Z = 1.04,P = 0.30） of ischemic stroke patients between theXingnao Kaiqiao needling and control treatment groups. However, theXingnao Kaiqiao needling method had a tendency towards higher efifcacy in mor-tality reduction and recurrence rates. TheXingnao Kaiqiao needling method was signiifcantly better than that of the control treatment in reducing disability rate （RR = 0.51, 95%CI： 0.27–0.98, Z = 2.03,P 〈 0.05）. CONCLUSION：TheXingnao Kaiqiao needling method has a better effect than control treatment in reducing disability rate. The long-term effect ofXingnao Kaiqiao needling against ischemic stroke is better than that of control treatment. However, the limitations of this study limit the strength of the conclusions. Randomized controlled trials with a strict, reasonable design, and multi-center, large-scale samples and follow-up are necessary to draw conclusions aboutXingnao Kaiqiao needling.
