ObjectiveTo explore risk factors of gastric paralysis following gastrectomy of gastric cancer and analyze its causes.
MethodsThe clinical data of 116 patients with gastric cancer for hospitalization time more than 21 days following gastrectomy were retrospectively analyzed from October 2011 to October 2013 in this hospital, in which 16 patients with gastric paralysis and 116 patients without gastric paralysis. The factors relevant gastric paralysis were analyzed by logistic regression analysis.
ResultsThe results of single factor analysis showed that the preoperative body mass index, history of diabetes, operative time, postoperative cardiovascular complications, albumin and hemoglobin levels within 3 d after operation, time to get out of bed after surgery, extubation time of gastric tube, the first drinking time and the first feeding time were associated with the gastric paralysis (P < 0.05), but the gender, age, time of diabetes history, life mode, smoking history, hypertension history, pylorus preserving or not, laparoscopy or not, intraoperative blood loss, intraoperative blood transfusion, uses of postoperative intraperitoneal chemotherapy drugs and postoperative analgesic drugs, and indwelling time of jejunum nutrition tube were not associated with gastric paralysis (P > 0.05). The results of logistic regression analysis showed that the preoperative body mass index, history of diabetes, operative time, time to get out of bed after surgery, and postoperative cardiovascular complications were the independent risk factors of gastric paralysis (P < 0.05).
ConclusionsThere are many factors that affect occurrence of gastric paralysis following gastrectomy of gastric cancer. Preoperative or intraoperative positive prevention measures could be taken according to the factors that might affect occurrence of gastric paralysis, which might be reduce gastric paralysis following gastrectomy of gastric cancer.
Objective To investigate the prognostic factors related to in-hospital mortality in patients with acute exacerbation of chronic obstructive pulmonary disease ( AECOPD) . Methods A prospective cohort study was carried out in AECOPD patients admitted in three district general hospitals of Jiangyou city, Sichuan province from February 2007 to February 2008. The clinical and epidemiological data at admission and all-cause death in hospital were recorded. The in-hospital mortality rate and potential determinants of mortality of AECOPD were analyzed using Logistic regression method. Results 257 AECOPD inpatients with AECOPD were recruited into the cohort study. The in-hospital mortality rate was 5.84% (15/257) . Univariate analysis showed in-hospital mortality was significantly associated with age, FEV1% pred, arterial oxygen tension ( PaO2 ) , arterial oxygen saturation ( SaO2 ) , pH, and Charlson’s complication index. Multivariate logistic regression model showed that lower arterial oxygen tension ( OR 4.775;95%CI 1.545 ～14.757; P =0.007) and higher Charlson’s complication index ( OR 4. 608; 95% CI 1. 330 ～15. 966; P =0. 016) were significantly associated with in-hospital mortality after adjustment by age. Conclusion For in-patients with AECOPD, PaO2 and Charlson’s complication index are independent risk factors associated with in-hospital mortality.
ObjectiveTo learn the outcomes of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) cases after artificial liver support system (ALSS) treatment and the relevant factors correlated with the clinical outcomes.
MethodsIn the period from January 2011 to June 2014, 321 patients with HBV-ACLF were admitted to West China Hospital. The clinical data at baseline, before and after treatment were analyzed by univariate and multivariate logistic regressions to identify the independent risk factors correlated with 30-day outcomes.
ResultsOf all the 321 patients, 233 survived and 88 died by the end of a 30-day observation. The univariate analysis identified that the incidences of cirrhosis, hepatorenal syndrome and peritonitis in the death group were significantly higher (P<0.05). The model for end-stage liver disease values, white blood cells (WBC), blood ammonia, creatinine and total bilirubin (TBIL) at different stages in the death group were significantly higher than those in the survival group (P<0.05). In the death group, the HBV-DNA, TBIL decrease after triple ALSS treatments, baseline prothrombin time activity (PTA) and PTA level after triple ALSS treatments were significantly lower (P<0.05). The multivariate logistic regression indicated that WBC (OR=2.337, P<0.001) and TBIL level after triple ALSS treatments (OR=4.935, P<0.001) were independent predicting factors for death within 30 days after ALSS treatment; HBV-DNA (OR=0.403, P<0.001), the decrease of TBIL after triple ALSS treatments (OR=0.447, P<0.001) and PTA level after triple ALSS treatments (OR=0.332, P<0.001) were protecting factors for the 30-day prognosis.
ConclusionThese five factors including WBC, HBV-DNA, PTA, TBIL and TBIL decrease after triple ALSS treatments influence the short-term prognosis for HBV-ACLF patients, which are valuable for decision making in clinical practices.
Objective To analyze the factors associated with the adoption of targeted therapy in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer and to generate evidence to inform decision-making on public security policy regarding innovative anticancer medicines for the benefit of patients. Methods The study population comprised female patients diagnosed with HER2-positive breast cancer and treated at Fujian Cancer Hospital from 2014 to 2020. The patients were eligible for targeted therapy. The demographic and sociological characteristics and clinical information of patients were extracted from the hospital information system. We performed binary logistic regression analysis of factors associated with the adoption of targeted therapy in patients with HER2-positive breast cancer. We also divided the participants into two groups according to their tumor stage for subgroup analysis. Results A total of 1 041 female patients with HER2-positive breast cancer were included, among them, 803 received targeted therapy. In September 2017, molecular-targeted medicines for HER2-positive breast cancer began to be included in the local basic health insurance program. Only 282 (35.1%) patients adopted targeted therapy before September 2017, after which this number increased to 521 (64.9%). Among the patients who adopted targeted therapy, most were formally employed (45.8%) and enrollees of the urban employee health insurance program (66.0%). Among those who did not adopt targeted therapy, most were unemployed (42.4%) and enrollees of the resident health insurance program (50.0%). Binary logistic regression analysis revealed that patient occupation, gene expression of estrogen receptor, tumor stage, surgery or not, radiotherapy or not, and undergoing treatment before or after September 2017 were correlated with the adoption of targeted therapy (P<0.05). Conclusions Inclusion of targeted medicines for HER2-positive breast cancer in the health insurance program substantially increased the overall administration of these therapies. Individual affordability is a critical factor associated with the application of targeted therapy in eligible patients. Future policies should enhance the public security of patients with a relatively weak ability to pay and provide insurance coverage for innovative anti-cancer medicines.
Objective To analyze and screen the risk factors of both immunohistochemistry and pathology for lung cancer lymphatic metastasis, and to build a mathematical model for preliminary evaluation. Methods By conducting retrospective studies, the information of lung cancer patients in the General Hospital of Air Force from 2009 to 2011 were collected. Both single and multiple unconditional logistic regression analyses were applied to screen total 27 possible factors for lymphatic metastasis. After the factors with statistical significance were selected, the relevant mathematical model was built and then evaluated by means of receiver operating characteristic (ROC) analysis. Results A total of 216 patients were included. The single analyses on 27 possible factors showed significant differences in the following 10 factors: pathological grade (P=0.00), age (P=0.00), tumor types (P=0.01), nm23 (P=0.00), GSTII (P=0.01), TTF1 (P=0.01), MRP (P=0.01), CK14 (P=0.02), CD56 (P=0.02), and EGFR (P=0.03). The multiple factors unconditional logistic regression analyses on those 10 risk factors screened 4 relevant factors as follows: pathological grade (OR=2.34), age (OR=1.02), nm23 (OR=1.66), and EGFR (OR=1.47). Then a mathematical diagnostic model was established based on those 4 identified risk factors, and the result of ROC analysis showed it could improve the diagnostic sensitivity and specificity compared with the single factor mathematical diagnostic model. Conclusion Pathological grade, age, nm23, and EGFR are related with lung cancer lymphatic metastasis, and all of them are the risk factors which have higher adjuvant diagnostic value for lung cancer lymphatic metastasis.
ObjectivesTo investigate the level of ankle-brachial index (ABI) of health examination population in Chongqing municipality and analyze the risk factors related to the level of ABI, so as to provide basis for effective evaluation of atherosclerotic lesions and their severity, as well as early detection, intervention and treatment of clinical cardiovascular diseases. MethodsA total of 22 886 subjects aged from 20 to 85 undergoing health examination in the medical examination center of First Affiliated Hospital of Chongqing Medical University in Chongqing municipality from January to December in 2016 were retrospectively analyzed. ABI and related physiological and biochemical data were collected. The relationship between ABI and age was analyzed using stepwise logistic regression model combined with restricted cubic splines. ResultsThe detection rate of abnormal ABI was 3.31% in 22 886 subjects undergoing health examination with 2.90% in males and 3.92% in females. The subjects aged below 40 presented the highest detection rate of abnormal ABI (6.17%) with 4.72% in males and 8.66% in females. The subjects were divided into two groups, one with ABI≤0.9 and one with ABI>0.9; the differences in age and levels of body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) between the two groups were statistically significant (allP<0.05). Multivariate stepwise logistic regression combined with restricted cubic splines showed that age, gender and BMI were presented as independent factors affecting ABI, among which the age below 40 (OR=2.885, 95%CI (2.445, 3.404),P<0.0001) was the main risk factor. A curve relating age to probability of abnormal ABI was produced after correcting for the influences of sex and BMI, stratified by gender and BMI into different subgroups, showing a U-shaped curve of decreasing initially and then increasing between the probability of abnormal ABI and age. ConclusionsThe detection rate of abnormal ABI based on individuals undergoing health examination in Chongqing municipality was 3.31%. A U-shaped curve of downward trend followed by an upward one was shown between probability of abnormal ABI and age after correcting for the influences of gender and BMI. The clinical significance of ABI≤0.9 for youth population (20 to 40 years old) without cardiovascular risk factors requires further exploration.
Objective To investigate the status of deciduous caries and early childhood caries among 3-5 year-old children of Uyghur and Chinese in Urumqi, and to explore the correlative factors of early childhood caries. Methods According to the criteria recommended by the Third National Oral Health Investigation, and Oral Health Surveys: Basic Methods of World Health Organization, the deciduous caries of 474 Urghur and Chinese children aged from three to five in nine kindergartens were clinically examined. Data were collected by questionnaire from their parents, and the result waw analyzed using Logistic regression analysis. Results The result of logistic regression analysis showed that the variables including nationality, frequency of drinking milk, eating cookie or drinking sweet beverage before sleep, brushing teeth with help, and educational background of the mother were closely related to the incidence of infantile caries. Conclusion The nationality, frequency of drinking milk, eating cookie or drinking sweet beverage before sleep, brushing teeth with help, and educational background of the mother are correlative factors of early childhood caries. Necessary methods for prevention of deciduous caries must be taken into consideration as early as possible, and the bilingual propaganda for preventing and treating caries should be also highly emphasized.
ObjectiveTo investigate the quality of life (QOL) and its influencing factors of patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer returning to social life after treatment.MethodsFunctional assessment of cancer therapy-breast scale (FACT-B Scale) was adopted to investigate the QOL of the HER2 positive breast cancer survivors, who were admitted and treated during January 2015 and October 2019 in Fujian Provincial Hospital. The demographic, social and economic data, as well as the clinical information of the responded survivors were collected. Logistic regression model was adopted to analyze factors associated with the QOL of the responded survivors.ResultsA total of 117 responded survivors were included. The median of the FACT-B scale was 106.0 (91.0, 121.3) points out of 148 points (71.6%). With the control of the demographic, social and economic status of the responded survivors, as well as the time from diagnosis and treatment to responding to the follow-up, we found that "having other chronic conditions" was the risk factor for the HER2 positive breast cancer survivors to have higher QOL in the social life after treatment (OR=4.17, 95%CI 1.33 to 15.37, P=0.01).ConclusionsThe overall QOL of the HER2 positive breast cancer survivors in the social life after treatment was low. "Having other chronic conditions" was the risk factor for the HER2 positive breast cancer survivors to have higher QOL in the social life after treatment.
ObjectiveTo analyze the risk factors of multidrug-resistant organism (MDRO) nosocomial infection, and to provide the scientific basis for the prevention and control of MDRO nosocomial infection.MethodsPatients with MDRO in Chengdu Shangjin Nanfu Hospital from 2014 to 2015 were retrospectively collected. The patients were divided into the MDRO nosocomial infection group and the MDRO non-nosocomial infection group. The MDRO infection/colonization, bacterial strain type, specimens type and distribution characteristics of clinical departments were analyzed. Single factor and multiple factor logistic regression analysis were used to analyze the risk factors of MDRO nosocomial infection.ResultsA total of 357 patients of MDRO infection/colonization were monitored, of which 147 times (144 patients) were with nosocomial infections and 213 times (213 patients) were without nosocomial infections. MDRO nosocomial infection incidence rate/cases incidence rate were 0.18%. A total of 371 MDRO bacterial strains were detected, of which 147 (39.62%) were with nosocomial infection and 224 (60.38%) were without nosocomial infections. The MDRO non-nosocomial infections included 175 strains (47.17%) in community infection and 49 strains (13.12%) in colonization. Carbapenem-resistant Acinetobacter baumannii (52.83%) was the main MDRO strains. Sputum (57.14%) and secretion (35.04%) were main specimens. The top three departments of MDRO nosocomial infection strains were orthopedics (32.65%), ICU (27.89%), neurosurgery (13.61%). ICU [odds ratio (OR)=3.596, 95% confidence interval (CI) (1.124, 11.501), P=0.031], surgical history [OR=2.858, 95%CI (1.061, 7.701), P=0.038], indwelling urinary catheter [OR=3.250, 95%CI (1.025, 10.306), P=0.045], and using three or more antibiotics [OR=4.228, 95%CI (1.488, 12.011), P=0.007] were the independent risk factors of MDRO nosocomial infection.ConclusionEffective infection prevention and control measures should be adopted for the risk factors of MDRO nosocomial infection to reduce the incidence rate of MDRO nosocomial infection.
Objective To approach the convenient prediction methods about surgical indications of adhesive ileus. Methods Two thousand and thirtyfour patients with adhesive ileus were analyzed retrospectively between January 1996 and January 2010 in the Department of General Surgery, The First Affiliated Hospital of Anhui Medical University， and 1 992 patients were included into this model. Seventeen factors which could influence the surgical decisions, including period of intestinal obstruction (X1), frequency of attack (X2), history of operation on abdominal region (X3), continuous and severe abdominal pain (X4), severe or frequent vomiting (X5), severe abdominal distention (X6), hemafecia (X7), fever (X8), heart rate (X9), shock or hypotension (X10), touching a swell ansa intestinalis (X11), hypoactive bowel sound (X12), peritonitis (X13), white blood cell (WBC) count of peripheral blood (X14), obstruction ansa interstinalis fixation and a severe expansion by abdominal erect position plain film (X15), peritoneal cavity free air (X16), and seroperitoneum whether or not by B ultrasonic examination (X17) were analyzed by binary logistic regression. Then prediction schedule whether patients with adhesive ileus needed emergency operation was gained by the theory of logistic regression analysis. Results Eight items were included in the prediction model by the method of forward stepwise which were X1, X2, X4, X9, X13, X14, X15, and X17, respectively. The probability of operation could be calculated by the following formula: logit(P)=expZ/（1+expZ）, where, Z={-7.813+〔-1.942×X1(1)/2.290×X1(2)/2.765×X1(3)〕+2.801×X2+2.692×X4+10.610×X9(1)/13.279×X9(2)+3.422×X13+〔-3.048×X14(1)/16.992×X14(2)〕+6.113×X15+2×X17}， which X1（1）, X1（2）, and X1（3） were periods of intestinal obstruction 3－5 d, 5－7 d, and ≥7 d, respectively. X9(1) and X9(2) were heart rates of 60－100/min and ≥100/min, respectively. X14(1) and X14(2) were WBC counts of peripheral blood of (10-20)×109/L and ≥20×109/L， respectively. The patient had to accept surgical procedure when the value of P was more than 0.5. The coincidence was 99.00%, sensitivity was 96.17%, specificity was 99.53% in 1 992 patients. The coincidence was 96.20%, sensitivity was 90.00%, specificity was 96.84% in 105 patients between January 2010 and April 2010 in this hospital. Conclusion The prediction schedule is a good useful value, but the coefficients is corrected following the cases increasing.
