ObjectiveTo analyze the related factors of cognitive impairment in patients with post-traumatic epilepsy. MethodsFrom January 2016 to January 2019, 45 patients with post-traumatic epilepsy (epilepsy group) and 48 patients with physical examination (control group) at the Department of Neurosurgery, the 904th Hospital of PLA were analyzed retrospectively. Cognitive assessment were evaluated by the following scales: Montreal cognitive assessment (MoCA), Mini-mental state examination (MMSE), Audio verbal memory test (AVMT), Rey-osterrieth complex figure test (CFT) and Trail making test (TMT). Then we analyzed the influences of gender, age, course of disease, cause, type, degree and location of injury, seizure frequency and Anti-seizure medications (ASMs) on cognitive impairment. ResultsThe results showed that there were significant differences between the epilepsy group and the control group in all scales (P<0.01). Analysis of influencing factors in epilepsy group showed: MoCA and MMSE scores: there were statistical significance in the comparison of seizure frequency and injury degree (P<0.05); AVMT, CFT and TMT scores: there were statistical significance in the comparison of seizure frequency, injury degree and location, ASMs within the group (P<0.05). ConclusionPost-traumatic epilepsy can cause cognitive impairment. The more frequent epileptic seizures and the more severe the degree of trauma, the more serious the cognitive impairment. Different injury sites affect the scope of cognitive impairment, temporal lobe injury is easy to cause memory function decline, frontal lobe injury is easy to cause spatial structure and executive ability decline, at the same time, the combined use of ASMs has an impact on cognitive function.
ObjectiveTo investigate the clinical characteristics and risk factors of patients with coronavirus disease 2019 (COVID-19), to provide a basis for clinical classification, diagnosis, and treatment.MethodsThe clinical data of COVID-19 patients comfirmed between January 17th and February 13th, 2020 were collected, single-factor test and multivariate logistic regression were used to compare the relevant indicators between the mild or common cases and the severe or critically severe cases.ResultsA total of 202 patients with COVID-19 were included, with an average age of 45.2 years and a male-to-female ratio of 1∶1.02. There were 146 patients (72.3%) without underlying diseases. The average time from onset to diagnosis was 5.4 d, and 31 were clustering epidemic cases. There were 13 (6.4%) mild cases, 151 (74.8%) common cases, 32 (15.8%) severe cases, and 6 (3.0%) critically severe cases. The main clinical symptoms were fever, cough, gasp, and diarrhea. Of the 202 patients, 135 (66.8%) had normal white blood cell count, 22 (10.9%) had lymphocyte ratio >40%, 18 (8.9%) had elevated aspartate aminotransferase (AST), 11 (5.4%) had elevated creatine kinase MB isoenzyme (CKMB), and 143 (70.8%) had elevated C-reactive protein (CRP). Single factor analyses showed that there were statistically significant differences between the mild or common cases and the severe or critically severe cases in the days of diagnosis, age, underlying disease, percentage of neutrophil, percentage of lymphocyte, arterial oxygen partial pressure, CRP, procalcitonin, lactate dehydrogenase, creatine kinase, CKMB, and AST (all P<0.05); multiple logistic regression analysis showed that CRP [odds ratio (OR)=1.035, 95% confidence interval (CI) (1.015, 1.055), P=0.001], CKMB [OR=1.078, 95%CI (1.023, 1.135), P=0.005], and AST [OR=1.042, 95%CI (1.016, 1.069), P=0.002] were correlated with clinical classification.ConclusionsCOVID-19 patients are mild or common cases mostly. CRP, CKMB, and AST are elevated in some cases, which may be related to early inflammation and certain myocardial damages and are independent risk factors for predicting classification.
ObjectiveTo evaluate the methodological quality of cross-sectional surveys about Chinese medicine syndrome in a population at potential risk of cerebrovascular diseases. Methods The CNKI, WanFang Data, CBM and PubMed databases were electronically searched to collect cross-sectional surveys about Chinese medicine syndromes in a population at potential risk of cerebrovascular diseases from inception to December, 2022. The methodological quality was assessed using the JBI scale. Results A total of 105 studies were included. The average reporting rate of JBI was 52.06%, and the items with the highest scores included "sufficient coverage of the identified sample in data analysis" (100%), "description of study subjects and setting" (92.38%), and "using valid methods for the identification of the condition" (86.67%). Items with the lowest scores included "adequate sample size" (13.33%), "adequate response rate or low response rate managed appropriately" (14.29%), and "study participants recruited in an appropriate way" (20.95%). Subgroup analysis suggested that type of publication and number of implementation centers were potential factors influencing methodology quality (P<0.05). Conclusion The methods essential to a cross-sectional survey such as sampling, sample size calculation and handling with the response rate, and the syndrome diagnosis scales specific to Chinese medicine require further improvement.
Objective To study the distribution and drug resistance of pathogens causing hospital-acquired pneumonia (HAP) and explore the related risk factors, so as to provide valuable clinical reference for prevention and treatment of HAP. Methods A case-control study was conducted in a 3700-bed tertiary hospital. Nosocomial infections reported from January 2014 to December 2014 were investigated. A total of 419 inpatients with HAP were enrolled in as a study group, and 419 inpatients without nosocomial infection in the same period and department, with same gender, underlying diseases, and same age, were chosen as a control group. Risk factors of HAP, distribution and drug resistance of pathogens of HAP were analyzed. Results The incidence rate of HAP was 0.62% and the mortality rate was 19.81%. Multivariate analysis identified chronic lung diseases, admission in ICU, two or more kinds of antibiotics used, hospitalization time≥5 days, cerebrovascular disease, and mechanical ventilation were significant risk factors. Totally 492 strains of pathogens were isolated, including 319 strains of gram-negative bacteria, 61 strains of gram-positive bacteria, 112 strains of fungi.Acinetobacter baumannii,Klebsiella pneumonia,Candida albicans,Pseudomonas aeruginosa,Candida glabrata ranked the top five predominant pathogens. Drug resistance rates ofAcinetobacter baumannii to commonly used antibiotics were higher than 75%. Drug resistance rates ofKlebsiella pneumoniae to piperacillin and third-generation cephalosporin were higher than 50%. Conclusions HAP prevails in patients with hospitalization time≥5 days, admission in ICU, cerebrovascular diseases, two or more antibiotics combined used, chronic lung diseases, and mechanicalventilation. It is associated with increased length of hospital stay, decreased quality of life, and elevated morbidity and mortality. The main pathogens of HAP are Gram-negatives.Acinetobacter baumannii andKlebsiella pneumoniae are resistant to the common antibiotics in different degree.
ObjectiveTo analyze risk factors of early outcomes of mitral valvuloplasty (MVP)for the treatment of degenerative mitral regurgitation (DMR). MethodsClinical data of 132 DMR patients who underwent MVP in Fu Wai Hospital between January 1, 2011 and November 1, 2011 were retrospectively analyzed. A total of 114 patients (86.4%)were followed up after discharge with their mean age of 51.21±12.78 years, including 76 males (66.7%). Preoperative risk factors of early outcomes of MVP were analyzed. ResultsAmong those patients, there were 25 patients with atrial fibri-llation (AF)(21.9%). Preoperative ejection fraction was 63.88%±6.93%. Preoperative echocardiography showed left ventricular end-diastolic diameter (LVEDD)was 31.61±5.51 mm/m2. There were 66 patients (57.9%)with tricuspid regurg-itation, and 34 patients (29.8%)underwent concomitant tricuspid valvuloplasty including 10 patients (8.8%)who received tricuspid annuloplasty rings. Two patients died postoperatively, 2 patients underwent re-operation of mitral valve replacement or MVP respectively. Postoperative echocardiography showed moderate or severe mitral regurgitation in 15 patients. Preoperative risk factors of early outcomes of MVP included AF (36.8% vs. 18.9%, P=0.035), large LVEDD (34.02±3.76 mm/m2 vs. 31.15±5.68 mm/m2, P=0.042)and functional mitral regurgitation (15.8% vs. 1.1%, P=0.007). Multivariate analysis showed greater postoperative LVEDD reduction significantly lowered the incidence of postoperative events (HR 0.002, 95% CI < 0.001-0.570, P=0.031). ConclusionsEnlargement of the left ventricle is an independent preoperative risk factor for early outcomes of MVP for DMR patients. Greater postoperative LVEDD reduction significantly lowers the incidence of postoperative events.
Objective To investigate the risk factors of perioperative red blood cells transfusion for coronary artery bypass grafting (CABG) surgery. Method We retrospectively analyzed the clinical data of 534 patients underwent CABG in our hospital from January to March 2014 year. Those patients were divided into two groups:an on-pump coronary artery bypass grafting group (on-pump group) and an off-pump coronary artery bypass grafting group (off-pump group). There were 185 males and 54 females with a mean age of 59.1±9.4 years in the on-pump group. There were 233 males and 62 females with a mean age of 60.3±8.5 years in the off-pump group. Preoperative data, the relative parameters of extracorporeal circulation, the quantity of red blood cells transfusion of those two groups were compared. risk factors associated with red blood cells transfusion were evaluated by multivariate logistic regression analysis. Results The risk factors of perioperative red blood cells transfusion were age (OR=1.04, 95% CI 1.02-1.07, P=0.001) , weight (OR=0.95, 95% CI 0.93-0.97, P<0.001) , smoking (OR=0.61, 95% CI 0.39-0.94, P=0.027) , preoperative level of HCT (OR=0.90, 95% CI 0.85-0.96, P=0.001) and cardiopulmonary bypass (CPB) (OR=4.90, 95% CI 3.11-7.71, P<0.001) . During CPB, the nadir hemoglobin (nHb) (OR=0.63, 95% CI 0.47-0.84, P=0.002) was the only independent risk factor of red blood cell transfusion. Conclusions Age, weight, non-smoking, preoperative level of HCT, CPB are the risk factors for patients underwent CABG perioperatively and the lowest level of Hb in CPB is an independent risk factor of perioperative red blood cells transfusion.
Abstract： Objective To analyze risk factors for perioperative mortality in the arterial switch operation (ASO), in order to provide better operation and decrease the mortality rate. Methods We enrolled 208 ASO patients including 157 males and 51 females at Fu Wai Hospital between January 1, 2001 and December 31, 2007. The age ranged from 6 h to 17 years with the median age of 90 d and the weight ranged from 3 kg to 43 kg with the median weight of 5 kg. Among the patients, 127 had transposition of great artery (TGA) with ventricular septal defect (VSD), and 81 patients had TGA with intact ventricular septum (IVS) or with the diameter of VSD smaller than 5 mm. Coronary anatomy was normal (1LCX2R) in 151 patients and abnormal in the rest including 15 patients with single coronary artery, 6 with intramural and 36 with inverse coronary artery. Preoperative, perioperative and postoperative clinical data of all patients were collected to establish a database which was then analyzed by univariate analysis and multivariate logistic regression analysis to find out the risk factors formortality in ASO. Results There were 24 perioperative deaths (11.54%) in which 12 died of postoperative infection with multiple organ failure (MOF), 10 died of low cardiac output syndrome, 1 died of pulmonary hypertension, and 1 died of cerebral complications. Among them, 20 patients (18.30%) died in early years from 2001 to 2005, while only 4 (4.00%) died in the time period from 2006 to 2007, which was a significant decrease compared with the former period (Plt;0.05). The univariate analysis revealed that cardiopulmonary bypass (CPB) time was significantly longer in the death group than in the survival group（236±93 min vs. 198±50 min, P=0.002）, and occurrence of major coronary events (33.3% vs. 2.2%, P=0.000) and unusual coronary artery patterns（33.3% vs. 6.5%,P=0.000） were much more in the death group than in the survival group. Multivariate logistic regression analysis showed that early year of [CM(159mm]operation (OR=7.463, P=0.003), unusual coronary artery patterns (OR=6.303,P=0.005) and occurrence of majorcoronary events (OR=17.312, P=0.000) were independent predictors for perioperative mortality. Conclusion The ASO can be performed with low perioperative mortality in our hospital currently. Occurrence of major coronary events, unusual coronary artery patterns and year of surgery before 2006 are independent predictors for perioperative mortality.
Objective To analyze the risk factors for duration of mechanical ventilation in critically ill patients. Methods Ninety-six patients who received mechanical ventilation from January 2011 to December 2011 in intensive care unit were recruited in the study. The clinical data were collected retrospectively including the general condition, underlying diseases, vital signs before ventilation, laboratory examination, and APACHEⅡ score of the patients, etc. According to ventilation time, the patients were divided into a long-term group ( n = 41) and a short-term group ( n = 55) . Risk factors were screened by univariate analysis, then analyzed by logistic regression method.Results Univariate analysis revealed that the differences of temperature, respiratory index, PaCO2 , white blood cell count ( WBC) , plasma albumin ( ALB) , blood urea nitrogen ( BUN) , pulmonary artery wedge pressure ( PAWP) , APACHEⅡ, sex, lung infection in X-ray, abdominal distention, and complications between two groups were significant.With logistic multiple regression analysis, the lower level of ALB, higher level of PAWP, lung infection in X-ray, APACHE Ⅱ score, abdominal distention, and complications were independent predictors of long-term mechanical ventilation ( P lt;0. 05) . Conclusion Early improving the nutritional status and cardiac function, control infection effectively, keep stool patency, and avoid complications may shorten the duration of mechanical ventilation in critically ill patients.
ObjectiveTo analyze the risk factors of cognitive dysfunction in patients with epilepsy, and provide evidence for clinical prevention and treatment.MethodsDuring the period from January 1, 2018 to January 31, 2019, 101 patients with epilepsy who were admitted to the epilepsy specialist clinic of the General Hospital of Ningxia Medical University were included in this study. The cognitive function of the patients was evaluated by the Mini-mental State Examination (MMSE) scale and patients were divided into cognitive impairment group and normal cognitive function group according to the MMSE. Single factor and logistic regression analysis were used to find the differences of influencing factors between the two groups.Results① There were 27 cases of cognitive dysfunction in 101 patients with epilepsy, the incidence of cognitive impairment was 26.7%; ② Univariate analysis showed that the course of disease, frequency of seizures, seizure forms, anti-epileptic drugs (AEDs) and abnormal rate of electroencephalogram (EEG) existed significant differences between the two groups (P<0.05). ③ Logistic regression showed that course of disease, frequency of seizures and AEDs multidrug therapy were independent risk factors for cognitive dysfunction in patients with epilepsy (P<0.05).ConclusionCourse of disease, frequency of seizures and AEDs multidrug therapy are independent risk factors for cognitive dysfunction in patients with epilepsy.
ObjectiveTo systematically review the risk factors leading to postoperative persistence of children diagnosed with obstructive sleep apnea (OSA) after adenoidectomy and tonsillectomy. MethodsPubMed, EMbase, The Cochrane Library, ClinicalTrials.gov, CNKI, VIP, WanFang Data and SinoMed databases were electronically searched to collect case-control studies and cohort studies related to risk factors for postoperative persistence of OSA in children from inception to July 2019. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 12 cohort studies involving 1 659 OSA patients were included. Meta-analysis results showed that the risk of postoperative persistence of OSA in children with preoperative obesity was 3.47 times higher than that in non-obese children (RR=3.47, 95%CI 2.04 to 5.92, P<0.000 01). Compared with normal-weight children, obese children had 4.11 times higher risk of postoperative residual OSA (RR=4.11, 95%CI 1.68 to 10.07, P<0.000 01).ConclusionsPreoperative obesity is a risk factor for postoperative persistence of OSA in children. Due to the limited quantity and quality of included studies, more high-quality studies are needed to verity the above conclusions.
