ABSTRACT

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

ABSTRACT

Objective:To develop the minimal clinically important difference (MCID) of Quality of Life Instruments for Cancer Patients-Leukemia (QLICP-LE) (V2.0).Methods:The quality of life of 101 patients with leukemia in First Affiliated Hospital of Kunming Medical University and First People′s Hospital of Yunnan Province from October 2011 to May 2012 were measured. The QLICP-LE (V2.0) was used for data collection, and the MCID for the overall score and scores of various domains of QLICP-LE (V2.0) were established by using the distribution-based approach including indexes of effect size, standard error of measurement (SEM), reliable change index, standardized response mean and responsiveness statistic, and the recommended values of MCID were determined through the consensus method.Results:The MCID formulated by the above five indexes were as follows: the total scale 1.4-9.3, physical functional domain 1.6-15.6, psychological functional domain 2.9-15.6, social functional domain 2.2-18.0, common symptoms and side-effects domain 1.7-17.1, common module 1.8-10.0, and the specific module 1.1-12.1. Through the expert consensus method, it was recommended to use the MCID results calculated by 1.96SEM: the total scale was 4, physical domain was 8, psychological domain was 8, social domain was 9, common symptoms and side-effects domain was 9, common module was 4, and the specific module was 6.Conclusion:Each index of distribution-based approach has its own advantages and disadvantages, which can be selected based on actual conditions. There is clinical significance when the score change of QLICP-LE (V2.0) of leukemia patients after treatment exceeds its MCID.

ABSTRACT

Objective:To understand the reliability and validity of quality of life instruments for cancer patients-brain neoplasm [QLICP-BN (V1.0)], a self-developed quality of life scale for cancer patients.Methods:The quality of life of 112 patients with brain neoplasms in Yunnan Cancer Hospital from March 2012 to November 2013 was measured. The general data questionnaire and QLICP-BN (V1.0) were used for data collection. The reliability, validity and responsiveness of the scale were tested, and then the metric characteristics of the scale were evaluated.Results:The split-half reliability of the total score of the scale was 0.95, the Cronbach αcoefficient was 0.92, and the test-retest correlation coefficient rwas 0.78. After extracting common factors by the principal component method and rotating with the maximum variance, the specific module obtained three principal components, and the cumulative variance contribution rate was 64.18%. The score of specific module was 75.30±17.44 before treatment and 78.91±12.20 after treatment ( t=-2.481, P=0.015). The total score of scale before treatment was 65.26±12.29, and that after treatment was 69.62±10.41, with a statistically significant difference ( t=-4.492, P<0.001). The total responsiveness of the scale was 0.456, showing moderate responsiveness. Conclusion:QLICP-BN (V1.0) has good reliability, validity and a certain degree of responsiveness. It can be used as a measurement tool for the quality of life of patients with brain neoplasms in China.

ABSTRACT

Objective:Lung ultrasound (LUS) has been used in the diagnosis of neonatal respiratory distress syndrome(RDS) successfully, but there have been no multicenter prospective studies to verify its reliability or determine how to grade RDS with LUS findings.This study aimed to discuss the necessity and feasibility of using LUS findings to determine RDS grades through a multicenter prospective study.Methods:Every researcher participated in the National Neonatal Lung Ultrasound Training Course and receiving 3-6 months of lung ultrasound system training at the National Neonatal Lung Ultrasound Training Center.Patients between June 2018 and May 2020 who met the RDS ultrasound diagnostic criteria and had full available clinical data were included in this study.The LUS examination was completed immediately after the patients were admitted to the hospital.Some of them also underwent chest X-ray examination.Arterial blood gas analysis was completed immediately before or after the LUS ultrasound examination.RDS grading was performed according to the LUS findings and whether the patient had serious complications.Results:A total of 275 qualifying cases were included in this study, which included 220 premature infants and 55 full-term infants, and the primary RDS occurred in 117 cases (42.5%), and secondary RDS occurred in 158 cases (57.5%). LUS manifestations of RDS patients can be divided into three categories: (1)A ground-glass opacity sign: which could be found among 50 infants when they were admitted to the hospital (that was, at their first LUS examination). Twenty-eight of these infants were considered to have wet lungs and were not sent for special management on admission, but LUS showed typical snowflake-like lung consolidation within 0.5 to 4 hours.Twenty-two of them were given mechanical ventilation with exogenous pulmonary surfactant; Eighteen cases were controlled within 6-12 hours, but the lung lesions became more severe in the other 4 infants (due to severe intrauterine infection). (2)Snowflake-like lung consolidations: the first LUS on admission showed typical snowflake-like lung consolidation involving areas ranging from 1-2 intercostal spaces to 12 lung divisions in 204 cases.Thirty-eight infants among them the lung consolidation only had involvement of 1-2 intercostal spaces at the time of admission; Fifteen of them received invasive respiratory support and recovered within 4-12 hours.Twelve patients received noninvasive respiratory support; Seven of them recovered, while five cases developed severe lung illness.The remaining 11 patients who were not given any form of ventilator support developed severe conditions within 1-4 hours.Thirty of them showed snowflake signs involving 12 lung regions at admission.The remaining 136 patients had lung consolidation degree between the two degree above condition.(3)Snowflake-like sign with complications: Twenty-one patients had severe complications such as pneumothorax, pulmonary hemorrhage or/and persistent pulmonary hypertension of the newborn or large area atelectasis, etc, although snowflake lung consolidation did not involve all lung regions.Conclusion:(1) LUS is reliable and accurate for diagnosing RDS.RDS has the same characteristics on ultrasound for both preterm and full-term infants, both primary and secondary RDS.(2) To facilitate the management of RDS, it is necessary to classify RDS according to the ultrasound findings and the presence of severe complications.(3) Based on the results of this study, it is recommended that RDS can be divided into mild, moderate and severe degrees.The exact standards for grading are as follows: Mild RDS: the early stage of RDS, in which lung consolidation shows as a ground-glass opacity sign on ultrasound; Moderate RDS: lung consolidation shows a snowflake sign on ultrasound, not all of the lung fields are involved; Severe RDS meets one or more of the following criteria: lung consolidation shows as a snowflake sign on ultrasound and all lung regions are involved, or regardless of its degree and extent, lung consolidation has caused serious complications, such as pulmonary hemorrhage, pneumothorax, persistent pulmonary hypertension of the newborn, or/and a large area of pulmonary atelectasis.

ABSTRACT

Objective To observe the effect of Shoutaiwan on the expression ofα-enolase in the decidua tissue of recurrent abortion mice. Methods The abortion-prone CBA/J × DBA/2 matings were established as the model of recurrent abortion and the nonabortion-prone CBA/J×BALB/C matings were used as the model of normal pregnancy. The model of recurrent abortion CBA/J × DBA/2 of pregnant mice were randomly divided into model group and Shoutaiwan high-, medium-, low-dose groups, pregnant mice of every group were orally administrated in different doses. On the 14th day of pregnancy, the mice were killed. The expression ofα-enolase was detected by using immunohistochemical method and Western Blot. Results α-enolase expression in the model group was significantly higher than the normal pregnancy group (P0.05). Conclusion Shoutaiwan could down-regulate the expression ofα-enolase in the decidua tissues of recurrent abortion mice, which may be one of its mechanisms of preventing miscarriage.

ABSTRACT

Objective: To evaluate the reliability of QLICP-GA (quality of life instruments for cancer patients-gastric cancer) scale by using generalizability theory, and to provide the references in order to revise and improve this scale. Methods: The mean squares of person (p), item (i) and the person-by-item interaction effect (pi) were calculated by using the module of UNIANOVA under the menu of General Linear Model in SPSS software. Furthermore, the generalizability coefficients and indexes of dependability were calculated in order to assess the reliability of QLICP-GA scale. Results: The largest source of variation in every domain was due to person-by-item interaction. The variances accounted for by person were large, while the variation accounted for by item was minimal. Generalizability coefficients of five domains were 0.774 (physical domain), 0.854 (psychological domain), 0.670 (social domain), 0.717 (common symptom and side effect domain), and 0.696 (specific domain), respectively. Conclusion: Physical domain, psychological domain and common symptom and side effect domain in QLICP-GA have good reliability. However, social domain and specific domain have acceptable reliability. Social domain should be emphasized when this scale will be revised and improved in future. The number of items of social domain should be added from 6 to 8 or 10. Secondly, the number of items of specific domain may be slightly added from 7 to 9. Copyright © 2013 by TUMOR.

Objective To investigate the tellurite resistance level,the presence of tellurite resistance (ter) gene cluster and their relationships in non-O157 Shiga toxin-producing Escherichia coli(STEC) isolates.Methods Tellurite resistance level was evaluated by plate dilution method and the ter gene cluster was tested by PCR.Results Only 5 of 39 non-O157 STEC isolates tested in this study were identified to have ter gene cluster,which showed relatively high levels of tellurite resistance ranging from 128 μg/ml to 512 μg/ml.In contrast,the other 34 isolates without ter gene cluster were sensitive to potassium tellurite and showed very low levels of tellurite resistance,the minimal inhibitory concentration (MIC) was <1 μg/ml for 29 isolates,8 μg/ml for 2 isolates and 2 μg/ml for 3 isolates.Conclusion Most non-O157 STEC isolates were sensitive to potassium tellurite.It could be concluded that much attention should be paid when screening the non-O157 STEC isolates using the selective medium supplemented with potassium tellurite.

ABSTRACT

Objective: To analyze the structure, reliability, validity and responsiveness of the six scales in the system of instruments measuring quality of life for patients with cancer (QLICP), which were developed to assess the quality of life for the patients with lung cancer, breast cancer, head and neck cancer, stomach cancer, colorectal cancer and cervical cancer. Methods: By using a stylized method, six QLICP-scales for lung cancer, breast cancer, head & neck cancer, stomach cancer, colorectal cancer and cervical cancer were developed. The quality of life of 692 patients with different tumors including lung cancer (n=85), breast cancer (n=186), head & neck cancer (n=133), stomach cancer (n=86), colorectal cancer (n=110) and cervical cancer (n=92) were measured. The reliability, validity and the responsiveness of the six scales were evaluated by calculating the Cronbach's α coefficient for the overall and each domain of the scale, calculating the test-retest reliability coefficient, and using exploratory factor analysis and the paired t-test. Results: All of the six scales in the system of QLICP have good structure and satisfactory psychometrics characteristics, which means that they have good reliability, validity and the tolerable responsiveness. Conclusion: The six special modules in the system of QLICP, including lung cancer, breast cancer, head and neck cancer, stomach cancer, colorectal cancer and cervical cancer modules, can be used in combination with general module of QLICP as the instrument to assess the quality of life for patients with different cancers.

ABSTRACT

Objective To investigate the incidence rate, onset time and electrophysiological characteristics of rapid eye movement sleep behavior disorder (RBD) and the relationship between RBD and synucleinopathies as well as the electrophysiological diagnostic criteria of RBD in Parkinson' s disease (PD) and multiple system atrophy (MSA). Methods Sleep survey and night video-polysomnography (NPSG)were used to study sleep disturbance of PD and MSA. (1) Subjective sleep assessments: All subjects,including 66 PD patients, 65 age and sex matched healthy controls and 30 MSA patients, completed the sleep questionnaires, and the RBD incidence rate and onset time were got. (2) Objective sleep assessments: 8 PD patients, 13 MSA patients, and 15 age and sex matched healthy controls underwent video-NPSG recording on two consecutive nights. Sleep architect were analyzed. The NPSG characteristics of RBD accompany with PD and MSA were analyzed, and the electrophysiological diagnostic varameters of it were determined. Results Patients with PD or MSA had a higher prevalence of RBD. RBD was found in 59. 1% (39/66) PD patients and 86. 6% (26/30) MSA patients, among those, 46. 2% ( 18/39 ) and 84.6% (22/26) had the waking symptoms of MSA and PD. The main NPSG characteristics of RBD of PD or MSA were chin REM without atonia (RWA) and increased movement. Conclusions The relatively higher RBD prevalence in MSA and PD patients indicates that RBD has close relationship with PD and MSA.Part of patients with RBD preceding neurology disease indicates that RBD may be the early marker of PD and MSA. The main NPSG characteristics of RBD accompany with PD and MSA are chin RWA and the motor manifestations. RWA and phasic EMG activity density are supposed to be the NPSG diagnostic parameters.
