RESUMEN

Objective:To explore the risk factors for malnutrition after a tracheotomy and to construct a predictive model useful for its prevention through early intervention.Methods:Clinical data describing 440 tracheotomy patients were subjected to a retrospective analysis. The variables examined were age, sex, etiology, Glasgow Coma Score (GCS), activities of daily living (ADL) score, age-corrected Charlson comorbidity index (aCCI), food intake, swallowing function, incidence of infections, as well as any history of diabetes mellitus, hypertension, smoking or alcohol consumption. Patients identified as being at risk of malnutrition (NRS-2002≥3) were screened using the Nutritional Risk Screening tool (NRS-2002) and the European Society of Clinical Nutrition and Metabolism′s ESPEN2015 criteria. The subjects were thus categorized into a malnutrition group of 343 and a control group of 97. Unifactorial and multifactorial logistic regression analyses were performed, and stepwise regression was applied to include the factors found significant in the unifactorial analysis into the multifactorial logistic regression analysis, and to construct a column-line graph prediction model. The clinical utility of the model was assessed by applying the receiver operator characteristics (ROC) curves, calibration plots and decision curve analysis (DCA).Results:Of the 440 persons studied, 343 (78%) were malnourished. The multivariate logistic regression analysis showed that pulmonary infection, dysphagia, low GCS score and high aCCI score were significant risk factors for malnutrition after a tracheotomy. A prediction nomograph was constructed. After fitting and correcting, the area under the curve (AUC) of the prediction model′s ROC curve was 0.911, the specificity was 80.4%, and the sensitivity was 91.3%. That was significantly higher than the AUCs for pulmonary infection (0.809), dysphagia (0.697), aCCI (0.721) and GCS (0.802). Bootstrap self-sampling was used to verify the model internally. After 1000 samples the average absolute error between the predicted risk and the actual risk was 0.013, indicating good prediction ability. The DCA results demonstrated that the model has substantial clinical applicability across a range of nutritional interventions, particularly for threshold probability values ranging from 0 to 0.96.Conclusion:Pulmonary infection, dysphagia, low GCS score, and high aCCI score are risk factors for malnutrition among tracheotomy patients. The nomogram model constructed in this study has good predictive value for the occurrence of malnutrition among such patients.

RESUMEN

Objective:To analyze the risk factors for malnutrition among disabled stroke survivors and devise a prediction model.Methods:A total of 373 disabled stroke survivors treated in the Department of Rehabilitation Medicine, the First Affiliated Hospital of Zhengzhou University in 2021 formed a control group ( n=102) and a malnutrition group ( n=271) according to their nutritional status. Univariate correlation analysis and multivariate logistic regression were used to analyze the risk factors for malnutrition and their predictive value. Results:Age, dysphagia, pulmonary infection, disability score and feeding style were found to be related significantly to the occurrence of malnutrition. Multivariate logistic regression confirmed that age, pulmonary infection, dysphagia, low total intake and a low Barthel index were useful predictors of malnutrition in such persons. Moreover, patients who had received nasogastric tube feeding were at much higher risk of malnutrition than those with intermittent oroesophageal tube feeding. The area under the receiver operating characteristics curve of the Barthel index combined with dysphagia to predict malnutrition was 0.84. The critical value was 0.67 with a sensitivity of 88% and a specificity of 72.5%.Conclusions:Age, pulmonary infection, dysphagia, feeding method, total intake and disability score are risk factors for malnutrition in disabled stroke survivors. The Barthel index combined with dysphagia has good predictive power for the occurrence of malnutrition in such persons.

RESUMEN

Objective:To investigate the value of applying B+ M type and shear-wave elastic ultrasound in determining the parameters of the geniohyoid muscles of stroke survivors with dysphagia.Methods:Forty stroke survivors with dysphagia formed an observation group, while 20 healthy counterparts were chosen as the control group. The thickness of the geniohyoid muscle, as well as the movement distance, time, rate and shear wave velocity were measured using B+ M ultrasound and shear wave elastic ultrasound when swallowing nothing or 5ml of water, respectively.Results:The average thickness of the geniohyoid muscle and the average shear wave velocity of the observation group were significantly smaller than among the controls. When swallowing either nothing or water, the geniohyoid muscle in the observation group tended to move farther than among the controls, acting more slowly and taking significantly more time.Conclusion:Ultrasound can quantify the thickness of the geniohyoid muscle and its motor parameters and stiffness. It can be used to evaluate the swallowing function of stroke survivors with dysphagia.

RESUMEN

Objective:To explore the prevalence of malnutrition among stroke survivors with bulbar palsy and the risk factors involved, and to construct a prediction model.Methods:This was a retrospective study of 325 stroke survivors. The nutritional status of those with and without bulbar palsy was compared. Univariate and multivariate logistic regressions were evaluated to highlight risk factors. A risk prediction model was constructed and a receiver operating characteristics (ROC) curve was drawn.Results:The prevalence of malnutrition among the stroke survivors with bulbar palsy was 66%, significantly greater than among all patients (52%). Among the stroke survivors with bulbar palsy there were significant differences between the normal nutrition group and the malnutrition group in terms of age, National Institutes of Health Stroke Scale (NIHSS) scores, hemoglobin, daily activities and pulmonary infection. The multivariate logistic regressions showed that pulmonary infection, a higher NIHSS score and lower hemoglobin were independent risk factors predicting malnutrition among stroke survivors with bulbar palsy. A risk prediction model for malnutrition was constructed based on the 3 major indicators and the area under the ROC curve was 0.86, with sensitivity of 0.79 and specificity of 0.83. A Hosmer-Lemeshow test indicated that the model was well calibrated, indicating that it would have good predictive value.Conclusions:Malnutrition is prevalent among stroke survivors with bulbar palsy. Pulmonary infection, a high NIHSS score and low hemoglobin are independent risk factors. They should be treated as important by medical staff.

RESUMEN

Objective:To explore the factors influencing the extubation time of patients in a persistent vegetative state (PVS) after tracheotomy so as to provide a theoretical basis for early extubation for such patients.Methods:Clinical data were collected on PVS patients after a tracheotomy. The cases were divided into an extubation group and a difficult extubation group according to whether the extubation was successful or not. Version 22.0 of the SPSS software was used to evaluate univariate and multivariate logistic regressions analyzing the factors influencing the success of extubation.Results:The single-factor analysis revealed significant differences between the groups in terms of average age, nursing level, nutrition, swallowing function, hypoalbuminemia and incubation time. Gender, brain injury, stroke, ischemic anoxic encephalopathy and lung infection were not, however, significant predictors. The multivariate logistic regression analysis highlighted nutritional mode, swallowing function, intubation time, pulmonary infection, full-time care and age as independent predictors of extubation success.Conclusions:Intermittent oral to esophageal tube feeding and full-time care are protective factors for extubation of patients in a PVS after a tracheotomy. Swallowing disorders, intubation for more than 30 days, pulmonary infection and greater age are risk factors for unsuccessful extubation. Nutritional support, swallowing function training and intensive nursing can effectively improve the success rate of extubation.

RESUMEN

Objective:To explore the effects of intermittent oral-esophageal tube feeding (IOE) on cerebral hemorrhage (CH) survivors receiving a tracheotomy.Methods:A total of 126 CH patients undergoing tracheotomy were randomly divided into an IOE group ( n=65) and a nasogastric tube feeding (NGT) group ( n=61). The feeding continued for 4 weeks along with medication and thorough rehabilitation interventions (including hemiplegic limb training, swallowing training, and pulmonary function training). Before and after the treatment, the body mass index, hemoglobin, albumin, proalbumin, creatinine height index, extubation rate and intubation time of the tracheotomy, as well as the incidence of complications were evaluated for both groups. Both groups were also assessed using the clinical pulmonary infection scale (CPIS) and National Institutes of Health stroke scale (NIHSS). Results:After the 4 weeks the nutrition indexes, average extubation rate (90.76%) and intubation time [(15.96±3.86)d], CPIS score (3.00±1.69), NIHSS score (11.86±4.08) and the overall incidence of complications in the IOE group were all significantly better than the NGT group′s averages.Conclusions:Where feasible, intermittent oro-esophageal tube feeding is superior to nasogastric tube feeding of cerebral hemorrhage patients undergoing tracheotomy. It reduces the risk of pulmonary infection and other complications, resulting in early removal of the tracheotomy cannula and quicker recovery.

RESUMEN

【Objective】 To investigate the clinical features and gene analysis of one pedigree with multiple endocrine neoplasia type 2A (MEN2A) so as to clarify the diagnosis and classification of the disease, guide treatment and prevention, and improve prognosis. 【Methods】 The clinical data of a 36-member MEN2A family, including 6 probands, with medullary thyroid carcinoma, were investigated, and the peripheral blood genomic DNA of 28 family members (blood sample of one proband was not collected) was extracted. PCR amplification was performed on exons 8, 10, 11, 13, 14, 15 and 16 of the RET gene, and the products were directly sequenced. 【Results】 Review of the medical history showed that two probands with medullary thyroid carcinoma were accompanied with hyperparathyroidism, and one family member had pheochromocytoma. The RET gene mutation test confirmed that 13 family members, consisting of 5 probands and 8 family members, had the RET proto-oncogene exon 10 missense mutation. The heterozygous missense had mutation c.1852T>A, leading to the conversion of cysteine (TGC) at position 618 to serine (AGC) (Cys618Ser). All subjects carrying RET gene Cys618Ser mutation had abnormal thyroid ultrasound change, accompanied with elevated calcitonin levels. Subjects carrying wild type of RET gene had normal calcitonin levels. The family was finally diagnosed with MEN2A by RET gene detection. 【Conclusion】 RET gene detection plays key role in the diagnosis and treatment of patients with MEN2A family and has guiding value in the follow-up and prognosis of asymptomatic carriers. There is a positive correlation between calcitonin level and the RET protooncogene mutation Cys618Ser. Patients suspected of MEN2A should be screened in time.

RESUMEN

Objective:To explore the effect of intermittent oro-esphageal tube feeding (IOE) on functional recovery from severe brain injury complicated by tracheotomy.Methods:A total of 98 patients with severe brain injury and tracheotomy were randomly divided into an observation group and a control group. All received neurotrophic and anti-infection medication, physical therapy, acupuncture and exercise. The observation group was also given intermittent oro-esophageal tube feeding, while the control group was given nasogastric tube feeding for 4 weeks. Before and after the treatment, each patient′s nutritional status, extubation time and extubation rate of the tracheotomy, and Glasgow Coma Scale score was evaluated as well as the incidence of complications.Results:After the 4 weeks the average hemoglobin, albumin and pre-albumin levels of the observation group and its average body mass index were all significantly better than the control group′s averages. It also had a significantly better overall incidence of complications, average extubation rate, average extubation duration and average GCS score.Conclusions:Where feasible, intermittent oro-esphageal tube feeding is superior to nasogastric tube feeding for improving the nutritional status and consciousness level of patients with severe brain injury. It promotes early removal of the tracheotomy cannula, which inhibits complications.

RESUMEN

Immunotherapy is becoming an effective and less invasive strategy that can be applied to the treatment of various malignancies. Lentiviral vectors (LVs) have shown great potential in immunotherapy as they can stably integrate relatively large foreign DNA, and effectively transduce dividing and non-dividing cells. Clinical application needs high quality LVs, and therefore strict quality control of the final products is necessary to ensure their purity, efficacy and safety. The quantitative detection of LVs is among the key parts of product development and quality control. In this paper, the existing methods for quantitative detection of LVs are summarized, including fluorescence activated cell sorter (FACS), P24 enzyme-linked immuno sorbent assay (P24 ELISA), real-time fluorescence quantitative polymerase chain reaction (RT-qPCR), nanoparticle tracking analysis (NTA), tunable resistive pulse sensing(TRPS) and virus counter(VC).Their advantages and disadvantages are listed, and future development and challenges are discussed.

RESUMEN

[ ABSTRACT] AIM:To cultivate stem-like spheres from SW620 cell line in the specific serum-free medium and evaluate the features of the cancer stem cells, and to investigate the effects of docosahexaenoic acid ( DHA) and eicosapen-taenoic acid ( EPA) on the growth of SW620 stem cell-like cells.METHODS: Human colon cancer stem cell-like cells ( CSCLC) were obtained from SW620 spheres cultured in serum-free medium.These cells were tested for the expression of SSEA-1 and TRA-1-81 by immunofluorescence staining.The mRNA expression of Sox-2 and Oct-4 was detected by real-time PCR.The efficiency of colony formation on a soft agar gel and tumor formation in the nude mice was compared between SW620 adherent cells and CSCLC.The inhibitory effects of 5-fluorouracil (5-FU) and mitomycin C on both types of cells were measured by MTS assay.MTS assay, Annexin V/PI staining and trypan blue staining were used to determine the effects of DHA and EPA on both types of cells.MTS assay was also used to analyze the combined effect of DHA or EPA with chemotherapeutic drugs on SW620 CSCLC.RESULTS:SW620 cells formed spheres in serum-free culture.The cells from spheres highly expressed SSEA-1 and TRA-1-81, transiently expressed Sox-2 and Oct-4 genes and were more resistant to 5-FU and mitomycin C treatments.These cells exhibited a greater ability in clone formation and tumorigenicity, indica-ting that these cells carried stem cell-like features, hence were considered SW620-derived CSCLC.DHA and/or EPA sup-pressed SW620 CSCLC by inhibiting cell growth, inducing cell apoptosis and sensitizing them to chemotherapeutic drugs. CONCLUSION:The cells with stem cell-like features, such as high efficiency in clonogenicity, tumorigenicity and resist-ance to chemotherapeutic drugs, can be obtained from SW620 spheres cultured in serum-free condition.DHA and EPA in-duce apoptosis in SW620-derived CSCLC and sensitize them to chemotherapeutic drugs.

RESUMEN

Object This experiment was conducted to study the relationship between CFTR gene expression in the intestinal tissues and secretory diarrhea.Methods Twenty-four Kunming mice were selected, half male and half female, and were randomly divided into 3 groups ( n=8 in each group):control group with intraperitoneal injection of 0.2 mL nor-mal saline, and the experimental group of mice by intraperitoneal injection of lipopolysaccharide(LPS) (6 mg/kg· bw). The mental state and intestinal morphology of the mice at 1 h and 8 h after LPS injection were observed to assess whether the secretory diarrhea model was successfully established.The expression of CFTR gene segments of intestine tissue was de-tected by fluorescence quantitative PCR.Results LPS induced secretory diarrhea.CFTR gene was expressed in the mouse duodenum, jejunum, ileum and colon tissues with different expression abundance.It was highest in the colon, but the difference was not significant between intestinal segments.Compared with the control group, LPS up-regulated the tran-scription level of CFTR gene in the duodenum, jejunum and ileum, and down-regulated the transcription of CFTR gene in the colon.Conclusions The results of our study suggest that the changes of the transcriptional level of CFTR gene are closely related with the diarrhea induced by LPS and the effects in different intestinal segments on the diarrhea is different. The jejunum plays a crucial role and the colon plays a least role in the Cl-secretion.

RESUMEN

Objective To investigate the effects of treadmill exercise on spatial learning,memory and the expression of hippocampal brain-derived neurotrophic factor(BDNF) in rats after mild traumatic brain injury (TBI).Methods Thirty Sprague-Dawley rats were randomly divided into group T (n =10,undergoing TBI modelling operation and 4 weeks' treadmill exercise training beginning at 48 h after the operation),group C (n =10,undergoing TBI modelling operation and no exercise training) and group N (n =10,undergoing sham operation and no exercise training).Morris water maze(MWM)was used to test rats' abilities of spatial learning and memory.The number of BDNF-positive cells in the hippocampus was measured with immunohistochemistry.Results In the orientational navigation test,the escape latency period was gradually shortened for rats in all groups.At the second training week,the average time of group T(88.54 ±5.73 s) became shorter than that in group C (91.45 ± 8.91 s).At the fourth week,however,the difference [(55.33 ± 6.77 s) vs (74.53 ± 6.85 s)] was significant(P < 0.01).Group N (88.44 ±7.79 s,79.52 ± 8.02 s,69.54 ± 10.14 s and 62.49 ± 7.22 s respectively) also improved significantly more than group C (98.99 ± 6.84 s,91.45 ± 8.91 s,79.65 ± 12.47 s and 74.53 ± 6.85 s respectively) from week 1 to 4 (P < 0.01).The average number of times of passing through the platform area of group N in four weeks (3.00 ± 0.54,3.38 ± 0.74,4.38 ± 1.06 and 6.00 ± 0.76 respectively) and group T from the second week on(3.25 ± 1.28,5.00 ± 0.93 and 5.88 ± 0.99 respectively) were significantly higher than that of group C (1.25 ± 0.71,1.50 ± 0.54,2.13 ± 1.25 and 3.00 ± 0.54 respectively) accordingly (P < 0.01).At the week four,the average number of BDNF-positive cells in group T(128.56 ± 7.93) were significantly larger than that in group C and group N (P < 0.05),with no significant difference was noted between group N and group C (P >0.05).Conclusions Treadmill exercise could improve the spatial learning and memory of rats after mild traumatic brain injury.This may be related with the up-regulation of expression of BDNF in the hippocampus.

RESUMEN

To obtain oleaginous yeast mutants with improved lipid production and growth rates, an atmospheric and room temperature plasma (ARTP) jet was used with a 96-well plate for high throughput screening. Mutants with changes in growth rates and lipid contents were obtained. At a lethality rate of 99%, the positive mutation rate of the yeast cells was 27.2% evaluated by the growth rates of the mutants and the comparison with the wild strain. The fermentation in a medium composed of yeast extract (10 g/L), peptone (10 g/L) and D-glucose (20 g/L) resulted in the lipid yield of the mutant (C4) with 4.07% (W/W) compared with that of the wild strain (1.87%).

RESUMEN

Objective To investigate the role of alprostadil on hepatic perfusion after transarterial chemoembolization(TACE) for hepatocellular carcinoma. Methods Sixty-four consecutive patients with HCC were randomized to either treatment with PGE_1 after TACE (treatment group, 32 cases) or no additional treatment after TACE (control group, 32 cases). In PGE_1 group, Lipo-PGE_1 was administered intravenously once a day for total of seven days, once after completion of TACE. The dosage of Lipo-PGE_1 was 0.4μg/kg and rote 0.05 μg·kg~(-1)·min~(-1). In control group, regular TACE was used. All patients underwent hepatic CT perfusion within 1 week before TACE and 4 weeks after TACE. The parameters of hepatic perfusion, including hepatic arterial perfusion value (HAP), portal vein perfusion value (PVP), total liver perfusion value (TLP) , and hepatic arterial perfusion index (HPI) were measured and compared. Chi-Square test was used for comparison of CT perfusion parameters in different stage, and t test was used for comparison of each CT porfusion parameter between two groups. Results In control group, HAP of pre-TACE, 4 weeks after first TACE, and 4 weeks after second TACE was (0.18±0.08), (0.22±0.09), (0.32±0.10) ml·min~(-1)·ml~(-1), respectively. Likewise, PVP was (1.11±0.31)、(0.82±0.27)、(0.59±0.25) ml·min~(-1)·ml~(-1), respectively, and TLP was (1.29±0.33), (1.04±0.28), (0.91±0.24) ml·min~(-1)·ml~(-1), respectively, and HPI was (14.31±6.36)%, (21.37±9.07)%, (36.67±13.42)%, respectively. The perfusion parameters at different stages of TACE were statistically different (F=19.71,27.47,14.75,41.41, P<0.05). In PGE1 group, HAP before TACE, after first TACE, and after second TACE was (0.17±0.08), (0.20±0.08), (0.26±0.08) ml·min~(-1)·mi~(-1) respectively, and PVP was (1.09±0.36), (1.03±0.40), (0.91±0.41) ml·min~(-1)·ml~(-1), respectively, and TLP was (1.26±0.38), (1.23±0.40), (1.17±0.44) ml·min~(-1)·ml~(-1) respectively, and HPI was (14.04±6.71)%, (17.26±7.86)%, (23.93±8.96)%, respectively. The difference of HAP and HPI at different stage of TACE was significant (F = 10.78, 13.05, P < 0.05), but there was no significant difference both PVP and TLP (F = 1.73,0.39, P > 0.05). The difference of PVP and TLP between the control and PGE1 group was significant after first TACE(t = -2.37, -2.14, P <0.05)and second TACE (t = 2.55, - 4.49, P < 0.05) In addition, after the second TACE, the HAP and HPI were also significantly different (t = - 3.41,5.09, P < 0.05). Conclusions PVP and TLP decrease while HAP and HPI increase after TACE. Lipo-PGE1 improves hepatic peffusion after TACE, exerting its greatest effect by increasing portal vein perfusion. Consequently, treatment with Lipo-PGE1 appears to increase liver tissue perfusion and thereby alleviate injury induced by TACE.
