RESUMO
Objective To investigate the status of self-advocacy and symptom burden in breast cancer patients undergoing chemotherapy and explore the correlations between them so as to provide a reference for relieving their symptom burden.Methods A total of 240 breast cancer patients undergoing chemotherapy who were treated in a general hospital in Hubei province from July 2021 to January 2022 were enrolled in the study by convenience sampling method.The general data questionnaire,female self-advocacy in cancer survivorship scale,and Chinese version of Anderson symptom assessment scale(MDASI)were applied in the investigation.Pearson correlation analysis was employed to explore the correlation between self-advocacy and symptom burden among breast cancer patients undergoing chemotherapy.Hierarchical regression was employed to analyze the effect of self-advocacy on symptom burden.Results A total of 240 patients completed the study.The total score of self-advocacy of the patients was(68.89±10.66),and the total score of symptom burden was(66.70±18.80).The two variables were significantly correlated in a negative way(r=-0.683,P<0.05).Hierarchical regression showed that self-advocacy ability independently explained 9.3%of the total variation in the symptom burden.Conclusions The incidences of various symptoms in breast cancer patients undergoing chemotherapy are high,and multiple symptoms coexist in the whole chemotherapy cycle.Symptom burden cannot be ignored,for it is negatively correlated with self-advocacy.Therefore,strengthening the concept and ability of self-advocacy can help reduce symptom burden of patients.
RESUMO
Background:This study aimed to investigate the changes in the clinical indicators and influencing factors of treatment duration among human immunodeficiency virus (HIV) patients in whom antiretroviral therapy (ART) was unsuccessful.Methods:In this retrospective study,a total of 9,418 HIV patients who failed in ART during 2004-2016 were included and divided into two treatment groups-Group 1 (treatment time ≤ 3 years,n1 =5,218) and Group 2 (treatment time ＞ 3 years,n2 =4,200).Patient follow-up data,including age,cluster of differentiation 4 (CD4) count,and viral load,glucose,creatinine,and triglyceride levels,were extracted from electronic health record databases.Covariance analysis for repeated measures was used to analyze the biochemical indicators,and multiple logistic regression modeling was used to compare relevant data extracted from the Group 1 and Group 2 HIV patient cohorts with different treatment time.Results:The median initial CD4 count was 175.0 cells/μl (interquartile range,77.0-282.0),while the initial CD4 counts for Group 1 were lower than those for Group 2 (P ＜ 0.05).A significant interaction between group and time effects was observed (P ＜ 0.05) in total cholesterol (TC).Changes in hemoglobin level among HIV patients were also significantly associated with treatment time (P =0.001).The initial CD4 count (odds ratio [OR] =0.756),female sex (OR =0.713),Zerit (d4T) (OR =1.443),TC (OR =1.285),and aspartate aminotransferase level (OR =1.002) were significantly associated with the survival time of dead patients with HIV (P ＜ 0.05).Additionally,the initial CD4 count (OR =1.456),age (OR =1.022),time interval (OR =0.903),patient's living status (OR =0.597),d4T (OR =2.256),and triglyceride (OR =0.930) and hemoglobin levels (OR =0.997) were significantly associated with the treatment time of HIV patients with drug withdrawal (P ＜ 0.05).Conclusion:The initial biochemical parameters can affect the survival and treatment time of HIV patients.With a comprehensive understanding of the physiological and biochemical indicators of patients,we can reduce the probability of drug withdrawal and prolong the survival time of HIV patients.
RESUMO
Placenta accreta spectrum (PAS) refers to the condition that placental trophoblast cells directly invade the myometrium,which is one of the most dangerous complications in obstetrics,but the pathogenesis has not been clarified.In recent years,the incidence of PAS was increasing,which has become the major reason leading to postpartum hemorrhage,perinatal emergency hysterectomy and maternal death.Available studies suggested that the occurrence of PAS was related to the following three interconnected factors:the loss of decidual membrane,enhanced trophoblast invasiveness and abnormal recasting of uterine spiral artery.This review focused on these three factors and tried to illustrate the pathophysiology of PAS.
RESUMO
Objective To evaluate the risk factors and sonographic findings of pregnancies complicated by placenta increta or placenta percreta. Methods Totally, 2219 cases were retrospectively analyzed from 20 tertiary hospitals in China from January 2011 to December 2015. The data were collected based on the original case records. All cases were divided into two groups, the placenta increta (PI) group (79.1％, 1755/2219) and the placenta percreta (PP) group (20.9％, 464/2219), according to the degree of placental implantation. The risk factors and sonographic findings of placenta increta or percreta were analyzed by uni-factor and logistic regression statistic methods. Results The risk factors associated with the degree of placental implantation were age, gravida, previous abortion or miscarriage, previous cesarean sections, and placenta previa (all P<0.05), especially, previous cesarean sections (χ2=157.961) and placenta previa (χ2=91.759). Sonographic findings could be used to predict the degree of placental invasion especially the boundaries between placenta and uterine serosa, the boundary between placenta and myometrium, the disruption of the placental-uterine wall interface and loss of the normal retroplacental hypoechoic zone(all P<0.01). Conclusions Previous cesarean sections and placenta previa are the main independent risk factors associated with the degree of placenta implantation. Ultrasound could be used to make a prenatal suggestive diagnosis of placenta accreta spectrum disorders.

RESUMO
BACKGROUND:For autoimmune diseases, it is difficult to effectively solve the lack of immunological tolerance in patients by traditional treatments. Mesenchymal stem cells have the biological functions of tissue and organ regeneration and immune regulation. OBJECTIVE:To explore the effects and mechanisms of human umbilical cord-derived mesenchymal stem cells on the development of thymus in nude mice. METHODS:Human umbilical cord-derived mesenchymal stem cells were intraperitoneal y injected into BABL/c nude mice at a dose of 2×106 per mouse. We analyzed the maturation and distribution of thymic epithelial cells in the thymus rudiment of nude mice and the thymopoiesis of this newly developed thymus rudiment;furthermore, we explored the therapeutic effects of human umbilical cord-derived mesenchymal stem cells. RESULTS AND CONCLUSION:Our data showed wel-organized cortex-medul a structure and an obvious improvement in the maturation of thymic epithelial cells in the rudiment. We further demonstrated the improved thymopoiesis and the enhanced export of mature T cells with the T regulatory cells increase in peripheral blood. Furthermore, we found that human umbilical cord-derived mesenchymal stem cells could be engrafted in the thymus and express many cytokines, especial y keratinocyte growth factor which is essential for the thymus development. These findings indicate that a new mechanism of human umbilical cord-derived mesenchymal stem cells can provide a proper microenvironment for the reconstitution and functional maturation of thymus in nude mice, and elicit another insight in terms of therapeutic efficacy of human umbilical cord-derived mesenchymal stem cells in many autoimmune diseases.
