ABSTRACT

Neurocognitive impairment is a group of clinical syndromes characterized by impaired cognitive function and decreased motor ability. Non-pharmacological interventions such as physical exercise have advantages in the treatment of patients with neurocognitive impairment. Multicomponent exercise is a combination of various physical exercises, including strength training, endurance training, balance training and flexibility training, that can improve gait, balance and cardiopulmonary function by increasing muscle mass, strength and endurance in people with neurocognitive impairment, while also reducing the risk of falls in elders. This article reviews the benefits of multicomponent exercise for patients with neurocognitive impairment and its evaluation methods; also describes 4 intervention programs and their clinical application, to provide evidence for clinical practice and promote the application of multicomponent exercise in patients with neurocognitive impairment.

ABSTRACT

Objective:To explore the assessment methodology for internal dose to workers exposed to 131I radionuclide. Methods:Workers were chosen in a 131I radiopharmaceutial manufacturer and a nuclear medicine department in a hospital using 131I to treat hyperthyroidism and thyroid cancer. A portable high purity germanium (HPGe) gamma spectrometer was used to measure the content of 131I in the thyroid for 4 consecutive times in a period of 7 d. The internal dose was estimated combining with the work rotation mode for workers dealing with 131I. Results:When the monitoring month was used as a typical month to estimate the internal dose, the annual committed effective dose was 0.09-1.93 mSv for the production staff engaged in the repackaging of 131I radiopharmaceuticals in the surveyed enterprise, and 0.06-0.58 mSv for the nuclear medicine staff in the surveyed hospital. After adjusting the monitoring result of the current monitoring period based on the rotation mode, the annual committed effective dose was estimated to be 0.06-1.22 mSv for radiopharmaceutical production workers and 0.03-0.15 mSv for nuclear medicine workers, respectively. Conclusions:In the assessment of internal dose to radiation workers exposed to 131I, using a single time measurement result to estimate the annual dose would lead to a larger error. In the case of continuous monitoring, the result of subsequent monitoring periods should be corrected according to the result of previous monitoring periods. In order to accurately estimate the internal dose of workers exposed to 131I, it is necessary to take full account of the 131I exposure pattern, time and frequency and the internal contamination route. For workers who may be exposed to 131I with potential internal dose greater than 1 mSv/year, a 14 day-routine monitoring period was appropriate.

ABSTRACT

Objective:To translate the English version and cross-cultural adaptation of Readiness for Return-To-Work Scale (RRTW) into Chinese and tested the reliability and validity of the Chinese version of RRTW in young and middle-aged stroke patients.Methods:RRTW was translated into Chinese with standard translation-retroversion. From August to December 2020, 235 stroke patients in the First Affiliated Hospital, College of Medicine, Zhejiang University were recruited by convenient sampling. The scale was tested by the reliability and validity.Results:The Chinese version of RRTW for stroke was composed of two parts: The first part was divided into four dimensions, with a total of 13 entries; For the unworked stroke population, the second part was divided into two dimensions, with a total of nine entries for the reworked stroke population. The content validity index (CVI) for each item was from 0.875 to 1.000. The total CVI for all items was 0.994. The Pearson correlation coefficient between dimension and scale was from 0.523 to 0.876. Four common factors were obtained from the first part and the cumulative contribution rate was 62.563%. Two common factors were obtained from the second part and the cumulative contribution rate was 49.908%. The Cronbach α coefficient in the first part was 0.760 and in the second part was 0.693.Conclusions:The Chinese version of RRTW for stroke patients has good reliability and validity, which can be used to assess the readiness level of stroke patients to return to work in Chinese society.

ABSTRACT

Objective:To investigate the incidence, clinical characteristics and risk factors for hip fractures in patients within two years after stroke onset.Methods:A total of 332 persons with first-onset stroke from the neurology department of our hospital between 1 June 2013 and 31 December 2014 were recruited and were divided into the hip fracture group and the non-hip fracture group.Clinical characteristics were recorded.Vision was tested as normal or impaired.Patients were accessed by the National Institutes of Health Stroke Scale(NIHSS), Behavioral Inattention Test, Baking Tray Task, Mini-Mental State Examination(MMSE), Birgitta Lindmark(BL)motor assessment scale, Berg Balance Scale(BBS), Timed Up & Go(TUG)Scale, and Stops Walking When Talking(SWWT)Scale.The clinic characteristics and risk factors for hip fractures were compared between the two groups after a 2-year follow-up.The accuracy of risk factors for fracture prediction was assessed by the sensitivity, specificity, and positive and negative predictive values.Results:Of 332 patients with stroke, 16 cases fractured their hips within two years after stroke onset, which corresponded to an incidence of 33‰/year(95% CI: 15‰/year-50‰/year). The 2-year mortality rate was 44%(95% CI: 25%-60%)and 48%(95% CI: 42%-54%)in patients with and without hip fractures respectively( χ2=0.036, P=0.724). The mean survival time for patients with and without hip fracture was 2.72 years(95% CI: 1.45-2.79)and 2.21 years(95% CI: 1.48-2.34)respectively.The proportions of patients with previous fractures history( χ2=16.780, P=0.041)and impaired vision( χ2=11.210, P=0.027), MMSE scale score( U=14.220, P=0.031), TUG ≥ 15 s( χ2=18.560, P=0.000)were higher, and SWWT( χ2=20.340, P=0.000)was lower in the hip fracture group than in the non-hip fracture group.The negative predictive values of previous fractures history, impaired vision, TUG and SWWT were higher than their positive predictive value.The specificities of previous fractures history, impaired vision, and SWWT were higher than their sensitivities.And the sensitivity of TUG was higher than its specificity. Conclusions:Hip fractures after stroke are common in elderly patients.Fractures often occur during daytime at home in daily activities.The previous fractures history, visual and cognitive dysfunction and impaired functional mobility are risk factors for hip fractures.We should take measures to prevent falls according to the relevant factors.Among the test scales, the timed up & go(TUG)scale could much more accurately identify patients at high risk for hip fractures.

ABSTRACT

Objective:To ascertain the basic situation of radiotherapy in Fujian in 2016.Methods:Based on the unified questionnaire, the types and quantity of radiotherapy and its corollary equipment, the number of radiotherapy staff and the work for quality control were surveyed in the radiotherapy units in the whole province, and the data on patients undergoing radiotherapy and other types of patients were collected from 26 hospitals. The total number of radiotherapy patients in the whole province was estimated by the correlation analysis and multiple linear regression analysis.Results:Radiotherapy was performed in a total of 32 hospitals in Fujian province in 2016. Among them, there were 62 sets of radiotherapy equipment, 33 sets of the simulators, 57 sets of treatment planning systems and 762 workers. The total number of 15 156 radiotherapy patients in 26 hospital were available for the survey. Multiple linear regression models showed that the frequency of application of medical electron accelerator was positively correlated with number of outpatients, emergency patients and inpatients, number of radiotherapy staff, number of electron accelerators ( r=0.311, 0.893, 0.956, P<0.05). Meanwhile, the frequency of aterloading brachytherapy was positively correlated with number of outpatients, emergency patients and inpatients, number of radiotherapy staff, number of aterloading brachytherapy units ( r=0.307, 0.966, 0.988, P<0.05). The frequency of radiotherapy was 0.54 patients per 1 000 population in Fujian in 2016. The delivered dose calibration of accelerators was performed in all hospitals involved in line with the relevant regulations, but the number of quality control equipment for radiotherapy was insufficient, such as the QA beam checker or well-type ionization chamber. Conclusions:In recent years, the rapid development of radiotherapy has been seen in Fujian province. The radiotherapy management should focus on standardenized and improved quality control and regulation in future.

ABSTRACT

Objective:To analyze the relationship between antithrombin Ⅲ(AT-Ⅲ) activity and survival, bleeding and thrombosis complications in patients with acute-on-chronic liver failure (ACLF), and to explore the prediction value of AT-Ⅲ activity in the prognosis of ACLF patients.Methods:The clinical data of 130 hospitalized patients with ACLF were retrospectively collected in Wuxi No.5 People′s Hospital from January 1, 2013 to April 1, 2019. The liver function, international normalized ratio (INR), and 90-day survival rate were detected. The AT-Ⅲ activity values at admission, week two, week four, and week eight of hospitalization were recorded, and the occurrences of fecal occult blood and femoral vein thrombosis were also recorded. The measurement data were compared by t test, analysis of variance, or rank sum test, and the categorical data were compared by chi-square test. The risk factors affecting the survival of ACLF patients were analyzed by Cox regression. The survival analysis was performed using the Kaplan-Meier method. Results:At the end of 90-day follow-up of 130 patients, 56 patients died, 20 patients (15.38%) were fecal occult blood positive and 15 (11.54%) had femoral vein thrombosis. The baseline AT-Ⅲ activity in the death group was lower than that in the survival group ((17.89±13.68)% vs (36.03±11.96)%), and the difference was statistically significant ( t=-8.045, P<0.01). The baseline AT-Ⅲ activities in fecal occult blood positive and negative patients were (18.26±11.52)% and (25.06±10.97)%, respectively, and in femoral vein thrombosis and non-thrombotic patients were (17.55±10.33)% and (32.48±11.88)%, respectively. The differences were both statistically significant ( t=8.746 and 8.090, respectively, both P<0.01). Through dynamic monitoring of AT-Ⅲ, the AT-Ⅲ activity showed a downward trend in the death group, while that showed an upward trend in the survival group, but the differences were not statistically significant ( F=0.282 and 0.401, respectively, both P>0.05). The Cox regression analysis suggested INR (odds ratio ( OR)=1.364, 95% confidence interval ( CI) 1.078-1.726, P=0.010) and AT-Ⅲ activity ( OR=0.930, 95% CI 0.906-0.954, P<0.01) were the independent factors affecting the survival of patients with ACLF. The area under the receiver operator characteristic curve of the AT-Ⅲ activity for predicting 90-day survival outcome of the patient was 0.706 (95% CI 0.773-0.952, P<0.01), and the cut-off value was 25%. Patients with AT-Ⅲ activity ≥ 25% had a higher survival rate than those with AT-Ⅲ activity <25% ( χ2=58.20, P<0.01). Conclusions:AT-Ⅲ activity is associated with fecal occult blood positive and femoral vein thrombosis in ACLF patients. The AT-Ⅲ activity is an independent influencing factor for predicting the prognosis of ACLF patients. Patients with AT-Ⅲ activity less than 25% have the higher mortality rate.

ABSTRACT

Objective@#To investigate the effect of cough assist on sputum excretion and the outcome of withdrawal of mechanical ventilation after mechanically ventilated chronic obstructive pulmonary disease (COPD) patients with cough weakness.@*Methods@#From January 2017 to December 2018, 74 patients with cough and weakness COPD after extubation of mechanical ventilation in the Department of Respiratory Critical Care Medicine of Hunan Provincial People's Hospital were divided into control group(n=37) and observation group (n=37) according to the random number table method. The patients in the control group were treated routinely after weaning and extubation, and the observation group was treated with cough assist after withdrawal of mechanical ventilation and extubation on the basis of the control group. The differences in drainage effect, blood gas index, reintubation rate and early prognosis index between the two groups were compared.@*Results@#After the intervention treatment, the first active sputum excretion and the total sputum volume on the first day were (5.6±3.4) ml and (33.1±5.2) ml in the observationgroup, and (4.2 ±2.0) ml and (29.1±7.4) ml in the control group, the difference was statistically significant (t=-2.10, 2.875, P<0.05). The number of significant cases of respiratory sound improvement in the observation group and the control group was 21 and 14 cases, respectively, and the difference between the two groups was statistically significant (Z=-1.974, P < 0.05). The oxygen partial pressure (PaO2) and oxygenation index (PaO2/FiO2) carbon dioxide partial pressure (PaCO2) values of the observation group were (80.0±8.4), (345.9±19.2), (46.7±6.6)mmHg, and (74.8±9.1), (310.7±21.9), (50.9±7.1)mmHg in the control group. The difference was statistically significant (t=-2.504,-2.710, 2.579, all P<0.05). The reintubation rate, noninvasive ventilation time, and hospitalization days after the initial extubation in the observation group were as follows: 5.6%(2/36), (64.1±18.9)h, (6.0±1.7)d, and 22.2%(8/36), (76.7±15.3)h, (7.2±2.8)d in the control group. The difference was statistically significant (χ2=4.181, t=2.528, 2.438, all P<0.05). The non-invasive ventilation rate within 72h in the observation group and the control group were 63.9% (23/36) and 75.0% (27/36), the difference was not statistically significant (χ2=0.222, P>0.05).@*Conclusions@#The application of cough assist in RICU patients with cough weakness after extubation by mechanical ventilation can improve the expectoration efficiency of cough, improve oxygenation, reduce carbon dioxide retention, reduce the rate of re-intubation, shorten the time of noninvasive ventilation and hospitalization after extubation, and improve the curative effect.

ABSTRACT

Lamin B1 is one of the essential members of the nuclear lamina protein family. Its main function is to maintain the integrity of nuclear skeleton, as well as to participate in the cell proliferation and aging by affecting the chromosome distribution. gene expression, and DNA damage repair. The abnormal expression of lamin B1 is related to certain diseases, including neurological diseases [e.g. neural tube defects (NDTs), adult-onset autosomal dominant leukodystrophy (ADLD)] and tumors (e.g. pancreatic cancer). It is also a potential tumor marker as well as drug target. Further research on lamin B1 will help people understand the molecular mechanism of the emergence and development of neural system diseases and tumors, and define a new future in drug target.

Objective@#To explore the characteristics underlying Th1/Th2/Th17 expression level after entecavir (ETV) discontinuation of chronic hepatitis B (CHB) patients who were HBeAg-positive and define the role of Th1/Th2/Th17 in maintaining virological response after ETV discontinuation.@*Methods@#We selected 112 HBeAg positive CHB patients who met the withdrawal criteria according to the guideline of prevention and treatment of chronic hepatitis B (2010 version), and we also separated them into virology sustained response (SVR) group and virological relapse (VR) group according to the recurrence in 52 weeks. We detected serum level of Th1/Th2/h17 related cytokines during 0, 12, 24 and 52 weeks follow-up to further analyze their dynamic changes and expression differences.@*Results@#The results of the study reveals that serum levels of IFN-γ in the group of SVR were at a higher level compared with VR group during follow-up (all P<0.05). While, the serum level of IL-10 decreased in SVR group and was lower than the paired IL-10 level in VR group with significance during follow-up. In VR group, the serum level of IFN-γ decreased during the first 24 weeks after ETV withdrawal, and after then, the level rose. The serum levels of IFN-γ (Th1) in SVR patients were significantly higher than those in VR patients in the different follow-up time points after ETV discontinuation (all P<0.05). And the serum levels of IL-10 (Th2) in SVR patients were significantly lower than that in VR patients (all P<0.05). The comparison of serum levels of IL-17A (Th17) between the two groups had no significant difference (all P>0.005).@*Conclusions@#The serum level of IFN-γ in SVR group maintained a high level is conducive to maintaining virological response after ETV withdrawal and high level of IL-10 may be related to virologic relapse.

ABSTRACT

Objective To examine the incidence ,clinical characteristics ,and risk factors for falls within two years after stroke in elderly patients. Methods A total of 365 elderly stroke patients from the Department of Neurology at the 8th Nanning People's Hospital were recruited from June 1 , 2013 to December 31 ,2014. They were divided into a fall group and a non-fall group and were followed up for two years. The incidence and clinic characteristics of falls were analyzed. The risk factors for falls were analyzed by multiple Logistic regression analysis. Results Of the 365 stroke patients included in this study ,falls were observed in 146(40.2% )patients. The interval between the stroke and the first fall :72(49.3% )patients had the first fall within 3 months;22(15.1% )occurred between 4 and 6 months;20 (13.7% )between 7 and 12 months ;17 (11.6% )between 13 and 18 months ;and 15 (10.3% )between 19 and 24 months.A hundred and five(71.9% )patients fell during daytime and 41 (28.1% )patients during night.Eighteen(12.3% )patients had one fall ;65(44.5% )patients fell 2 to 4 times ;60(41.1% )patients fell 5 to 10 times ;and 3(2.1% )patients fell over 10 times.A total of 709 falls were observed.Places of falls :102(69.9% )falls happened indoors and 44(30.1% )falls occurred outdoors.Circumstances of falls :27 (18.5% )patients fell when turning over ;23 (15.8% )fell when rising from a seating position ;4(2.7% )patients fell when showering ;15(10.3% )patients fell while standing ;9(6.8% )fell when turning around ;56(38.3% )fell while walking ;and 12(8.2% )fell while climbing the stairs or running.The severity of falls :52(35.6% )patients had no injury ;78(53.2% ) suffered soft tissue injury ;16 (11.0% )had fractures ;and 78 (53.2% )had fear of falling.Multiple Logistic regression analysis showed that age(OR=2.41 ;95% CI :1.69-3.05) ,history of falls(OR =2.85 ;95% CI :1.46-3.81) ,history of stroke(OR=1.87 ;95% CI :1.12-2.79) ,right hemiplegia(OR=2.37 ;95% CI :1.62-4.59) ,left hemiplegia(OR= 2.47 ;95% CI :1.46-4.78) ,paraplegia(OR= 2.55 ;95% CI :1.57-4.98) ,visual impairment(OR=2.35 ;95% CI :1.35-6.62) ,apraxia(OR=2.53 ;95% CI :1.42-5.63) ,unilateral spatial neglect (OR=3.34 ;95% CI :2.82-6.34) ,use of psychotropic medications (OR= 1.76 ;95% CI :1.11-1.98) ,impaired physical mobility (OR = 1.58 ;95% CI :1.82-2.91) ,low MMSE scale(OR = 3.42 ;95% CI :1.38-7.41) ,low Barthel Index score(OR = 2.83 ;95% CI :0.97-4.68) ,BBS scale<45(OR=2.48 ;95% CI :1.27-4.18) ,TUG>15seconds(OR=3.56 ;95% CI :1.91-5.23) ,and lack of rehabilitation therapy (OR=3.42 ;95% CI :1.38-7.41)were independent predictors for falls(all P<0.05). Conclusions Falls are common among elderly patients within two years after stroke.Most falls happen indoors ,during daytime and while moving.Age ,history of falls ,history of stroke ,hemiplegia ,visual impairment ,apraxia ,unilateral spatial neglect ,use of psychotropic medications ,walk with a walker ,low MMSE scale ,low Barthel Index score ,BBS scale<45 ,TUG>15 seconds ,and lack of rehabilitation therapy are independent risk factors for falls after stroke.
