ABSTRACT
Objective To investigate cancer patients′nutritional status after operative treatment and analysis of risk factors for malnutrition, which provides the basis for maintaining patients′ nutrition support after discharge. Methods One hundred and thirty patients treated with tumor in Liuan Hospital affiliated to Anhui Medical University were investigated. The nutritional status of patients discharged from hospital was evaluated by subjective comprehensive assessment, and the risk factors of malnutrition when they were discharged from hospital were analyzed. Results In 130 patients, 76 patients (58.46%) were assessed as no or mild malnutrition, and 54 patients (41.54%) as moderate or severe malnutrition. Univariate analysis showed that body mass index < 18.5 kg/m2 at admission, nutritional risk screening 2002(NRS2002) ≥ 3 scores, smoking and drinking were related to the occurrence of malnutrition after tumor surgery (P<0.05). Logistic regression analysis showed that NRS2002≥3 scores at admission and smoking were independent risk factors for malnutrition at discharge (P < 0.05). Conclusions The incidence of malnutrition in patients after tumor surgery is high, and there are many risk factors. Therefore, early nutrition support should be provided to patients, and family nutrition intervention after discharge is also very necessary.
ABSTRACT
Objective@#To investigate the incidence rate of nutritional risk and malnutrition in patients with acute cerebral infarction, and analyze the influence factors of nutritional risk and malnutrition, so as to provide evidence for targeted nutritional intervention.@*Methods@#Nutritional risk screening 2002 (NRS2002), subjective global assessment (SGA) and body mass index (BMI) were applied to screen nutritional risk and assess nutritional state for hospitalized patients with acute cerebral infarction from January to October 2017, and to investigate the incidence rate of nutritional risk and malnutrition. Univariate analysis was used to analyze the relationship of nutritional risk and malnutrition with the basic information and habits of patients. Logistic regression was used to analyze the independent risk factors.@*Results@#The incidence rate of the nutritional risk (NRS2002 ≥ 3 scores) was 61.0% (122/200) in 200 cases of acute cerebral infarction patients. If BMI<18.5 kg/m2 was used to evaluate the nutritional deficiencies, the incidence rate of undernutrition was 8.5% (17/200). The incidence rate of malnutrition was 25.5% (51/200) using the SGA evaluation method. The univariate analysis showed that the nutritional risk was associated with age, drinking, combined infection, fluid diet, dysphagia/cough, and BMI (<18.5 kg/m2)(P<0.05 or<0.01), and the malnutrition was associated with age, combined infection, disturbance of consciousness, fluid diet, dysphagia/cough and BMI (<18.5 kg/m2) (P<0.01). Logistic regression analysis showed that the age, fluid diet were the independent risk factors for nutritional risk (P<0.05 or<0.01). The age, combined infection, fluid diet and BMI (<18.5 kg/m2) were the independent risk factors of malnutrition (P<0.05 or<0.01).@*Conclusions@#The incidence of nutritional risk and malnutrition in patients with acute cerebral infarction is relatively high. Nutritional risk screening and nutritional assessment should be performed at the time of admission. Early nutrition intervention should be used to prevent malnutrition and improve the prognosis of patients.
ABSTRACT
Objective To explore the effects of maternal cypermethrin exposure during lactation on testicle development and steroidogenesis of weaning offspring, and to provide a theoretical basis for the toxicity study of cypermethrin on reproduction.Methods Twenty-one healthy pregnant mice(clean animal) were randomly divided into three groups.Maternal mice were orally administered with different doses of cypermethrin [0,6.25 and 25 mg(/kg?d),10 ml/kg] dissolved in corn oil daily from postnatal day 1(PND1) to PND21.Fifteen male pups were randomly selected from each group and sacrificed at PND21 after exposure.The testicle organ coefficients were calculated.Serum testosterone(T) and estrogen(E2),testicle T were measured by radioimmunoassay(RIA).Histopathological changes in the testicle tissues were observed by HE stain.Testicle cells apoptosis was detected by TdT-mediated dUTP nick end labeling(TUNEL).Results A significant decrease was observed in body weight and the testicle organ coefficients in cypermethrin-treated group was in a dose-dependent manner(P0.05).Histological examination showed that maternal cypermethrin exposure markedly decreased the number and layers of spermatogenic cells,increased the inside diameter(ID) of seminiferous tubules,and disturbed the array of spermatogenic cells in testicle sections of pups at PND21.No significant effect on apoptosis of testicle cells was seen.Conclusion Maternal cypermethrin exposure during lactation may damage testicles and steroidogenesis of weaning offspring.
