ABSTRACT
RESUMEN La seguridad del paciente es un elemento imprescindible de la calidad asistencial. Al menos la mitad de los eventos adversos en pacientes hospitalizados están en relación con la práctica quirúrgica. El Análisis Causa-Raíz es un estudio sistemático de estos eventos mediante una revisión paso a paso de la cronología de los hechos, para identificar las causas que podrían haber llevado a la producción del evento. El Diagrama de Ishikawa o "espina de pescado" es una herramienta gráfica es una herramienta útil. El éxito radica en lograr responder qué sucedió, por qué sucedió, y qué puede hacerse para evitar que suceda nuevamente algún evento que vulnera la seguridad del paciente. El propósito último es la mejora de los procesos asistenciales impidiendo la repetición del evento adverso y priorizando el aprendizaje y mejora a partir de su análisis. La comunicación institucional de los hallazgos del análisis y las medidas para implementar, la discusión de casos en ateneos de morbimortalidad y la educación continua del personal son pilares para el cambio en la cultura hacia una centrada en la seguridad y calidad, sustituyendo la cultura "reactiva" por una "proactiva", que toma los eventos como instrumento para el aprendizaje y la mejora continua.
ABSTRACT At least half of the adverse events on hospitalized patients are associated with surgery. Root cause analysis (RCA) is a systematic way of analyzing these events to find their causes through a step-by-step review of the chronology of facts, identifying those that could have caused the event. An Ishikawa diagram (also called fishbone diagram) is a visual method for root cause analysis that allows the identification and categorization of all possible causes of an event. The goal is to answer what happened, why did it happen, and what can be done to prevent it from happening again. The ultimate goal is to improve healthcare processes by preventing the recurrence of the adverse event and prioritizing learning and improvement based on its analysis. Communicating the findings of the analysis and the measures to be implemented, discussing cases in morbidity and mortality meetings and continuous education of staff are the cornerstones for changing the culture towards one centered on safety and quality, replacing the "reactive" culture with a "proactive" culture, which considers events as an instrument for learning and continuous improvement.
ABSTRACT
Introduction: Turnaround time (TAT) is one of the most crucial performance indicators for blood transfusion and laboratory services. It is especially crucial in transfusion services due to its seminal role as a determining factor in patient care outcomes. We examined our institution’s TAT for issuing blood units. Materials and Methods: The Department of Immunohematology and Blood Transfusion, MGM Medical College and Hospital in Navi Mumbai, Maharashtra, India, undertook this retrospective noninterventional study over 12 months from January 01, 2020 to December 31, 2020. TAT was determined using a random audit of 10% of all monthly requests at the blood center. All requests for packed red cells (PRCs) received in the blood center during the study period were included in the evaluation. All requests for other blood components such as fresh-frozen plasma, random donor platelets, and cryoprecipitates were excluded along with all reservations for PRCs. A team of investigators tracked 369 requests for packed red cells over the year, noting the turnaround time. The standard TAT was set depending on the nature of the clinical case. Any significant deviation from institutionally established TAT was investigated, and root cause analysis was done. Results: The majority of transfusion requests were routine (72%) followed by emergency (23%) and lifesaving (5%). For routine cases, the average TAT was observed at 104 minutes. For emergency cases, the average TAT was observed at 39 minutes. For lifesaving cases, the average TAT was observed at 12 minutes. The highest number of cases were categorized under routine, followed by emergency cases and lifesaving categories. Conclusion: It was observed that there were no significant variations in turnaround time in routine, emergency, or lifesaving cases. Overall, as per our blood center standards, TAT for the issue of packed red cells was observed to fall under the normal range for routine, emergency, and lifesaving. Any outliers observed during the duration of the study were mainly due to inadequate samples or patient details received at the blood center or the presence of irregular antibodies encountered during the crossmatch.
ABSTRACT
Objective:To systematically evaluate the risk factors of implantable venous access port-related bloodstream infections and provide basis for prevention of catheter-related bloodstream infection in tumor patients.Methods:The Cochrane Library, PubMed, EMBASE, Web of science, CNKI, Wanfang database, VIP database, CBM, Chinese and English Clinical trials Registry (ChiCTR) were searched to collect the literature on risk factors for implantable venous access port-related bloodstream infections in tumor patients from the establishment of the database to April 2022. Two evaluators independently screened and extracted the obtained literature according to the inclusion and exclusion criteria, and used the Newcastle-Ottawa Scale for quality evaluation. Meta-analysis was conducted by RevMan 5.3 software and Stata SE/MP(14.0 version).Results:A total of 13 studies were included, including 23 related risk factors. Among them, prolonged use of catheters, palliative treatment, hematological tumors, neutropenia, hospitalized patients, and chemotherapy were risk factors for implantable venous access port-related bloodstream infections in tumor patients, with statistically significant differences ( OR values ranging from 0.26 to 8.77, all P<0.05). Conclusions:The long time of catheter use, palliative treatment, hematological tumor, neutropenia and chemotherapy were the risk factors of implantable venous access port-related bloodstream infection in patients with tumor, Medical personnel should make a good assessment and strengthen health education to minimize the chances of infection and effectively reduce the incidence of infection related to the infusion port.
ABSTRACT
Objective:To analyze the failure rate of enteral nutrition feeding in patients with mechanical ventilation, explore the influencing factors, and find out the existing problems and deficiencies in the process of nutrition support.Methods:Patients who were admitted to the ICU of Zhejiang People′s Hospital from June 2020 to January 2022 for mechanical ventilation and continuous enteral nutrition through the nose were retrospectively collected as the research subjects. The patients were divided into a standard group and a substandard group. Comparing the feeding status of enteral nutrition patients in the two groups on the 7th day, Logistic regression was used to analyze the influencing factors of feeding substandard.Results:A total of 82 patients (57.34%, 82/143) had feeding failure. Logistic regression analysis showed that complications ( OR=34.47, 95% CI 9.49 to 125.21) and infusion speed ( OR=0.21, 95% CI 0.08 to 0.57) were the influencing factors of feeding failure in ICU mechanical ventilation patients ( P<0.05). Conclusions:The feeding failure rate of ICU mechanical ventilation patients is higher than the feeding failure rate, and the slow infusion speed caused by complications and feeding intolerance is the main reason for the failure. It is suggested to set personalized feeding program for patients, optimize feeding measures, and improve the feeding failure rate.
ABSTRACT
Objective:To investigate the status of social alienation in maintenance hemodialysis (MHD) patients, and analyze its correlation with self disclosure and social support.Methods::From May 2019 to March 2021, 156 MHD patients admitted to Nanyang Central Hospital were selected as the research objects by using convenient sampling method. A cross-sectional survey was conducted by using general information questionnaire, general alienation scale, pain disclosure index scale and social support scale.Results:A total of 176 questionnaires were issued, with an effective recovery rate of 88.64%(156/176). The social alienation score of 156 patients with MHD was (41.57±4.89) points, which was at the upper-middle level and negatively correlated with the total scores of the Distress Disclosure Index and the Perceived Social Support Scale ( r=-0.526, -0.284, all P<0.01). The results of multiple linear regression analysis showed that age, educational level, and per capita monthly household income were the main factors affecting social alienation ( β=0.199, -0.361, -0.290, all P<0.01). After controlling for the above factors, self disclosure and social support independently explained the variance of social alienation in MHD patients increased by 20.2% ( β=-0.440, -0.200, all P<0.01). Conclusions:MHD patients have a high sense of social alienation. Medical staff should pay attention to patients who are older, less educated, and have low family income. Self disclosure and social support are modifiable variables, so medical staff can reduce their social alienation and improve the quality of life by training patients on self disclosure and improving the level of social support.
ABSTRACT
Objective:To investigate the current smoking status and smoking abstinence self-efficacy of stroke smoking patients, to clarify the factors associated with the smoking abstinence self-efficacy in stroke patients, and to provide a theoretical basis for subsequent targeted interventions and guidance for smoking cessation.Methods:A total of 196 stroke patients admitted to the Neurology Department of Tianjin Huanhu Hospital from September to December in 2021 were surveyed adopted cross-sectional survey method by the General Information Questionnaire, the Fagerstrom Test for Nicotine Dependence, the Tobacco Hazard Perception Score, and the Smoking Abstinence Self Efficacy Scale. Multiple linear regression was used to analyze the factors associated with patients' smoking abstinence self-efficacy.Results:The overall score of self-efficacy for smoking in stroke patients was (20.78 ± 6.47), and the scores of each dimension in descending order were habit/addiction, negative/emotional and positive/social situations. Multiple linear regression analysis showed that occupation, nicotine dependence score and cognition score of tobacco harm were the influencing factors of smoking abstinence self-efficacy, which could explain 37.4% variation of smoking abstinence self-efficacy.Conclusions:The self-efficacy level of smoking patients with stroke needs to be improved, and helping patients to improve their perception of tobacco harm and reduce their nicotine dependence can improve their self-efficacy level to increase the success rate of smoking cessation, thus reducing or even quitting the health risks caused by smoking behavior.
ABSTRACT
Objective:To analyze the incidence of stillbirth and the associated factors in pregnancy among pregnant residents in Wuhan.Methods:A previous birth cohort was retrospectively reviewed. The cohort was based on Wuhan Maternal and Child Information System, and the perinatal information of pregnant residents in Wuhan from January 1, 2011, to September 30, 2017 and information of selected cases was collected, including socio-demographic characteristics, pregnant history, and healthcare information during pregnancy and labor. Data on stillbirth, including fetal death in uterus and in labor, were selected for this study. Chi-square test was adopted for comparing the differences in pregnancy-related factors between live birth and stillbirth, and binary logistic regressions for exploring the influencing factors associated with the occurrence of stillbirth. Results:A total of 509 057 deliveries in Wuhan were included in this study, including 505 839 live births and 3 218 stillbirths (3 155 after exclusion of fetal death in labor), with an overall incidence of stillbirth of 6.32‰(3 218/509 057), and an annual incidence between 4.90‰ to 8.11‰. Statistically significant differences were found between the live birth and stillbirth group in the following items: maternal age [<25 years old: 19.28% (97 544/505 839) vs 19.36% (623/3 218); 25-30 years old: 48.45% (245 077/505 839) vs 45.15% (1 453/3 218); 30-35 years old: 26.09% (131 952/505 839) vs 26.29% (846/3 218); >35 years old: 6.18% (31 266/505 839) vs 9.20% (296/3 218)], educational background [middle school or below: 22.90% (115 833/505 839) vs 22.03% (709/3 218); high school: 36.37% (183 978/505 839) vs 38.72% (1 246/3 218); college or above: 40.73% (206 028/505 839) vs 39.25% (1 263/3 218)], occupation [brainworker or professionals: 33.51% (169 514/505 839) vs 31.54% (1 015/3 218); manual or freelance worker: 66.38% (335 763/505 839) vs 68.34% (2 199/3 218)], residential area [urban area: 70.00% (354 365/505 839) vs 76.32% (2 456/3 218); rural area: 30.00% (151 474/505 839) vs 23.68%(762/3 218)], and time of conception [spring (March to May): 24.27% (122 746/505 839) vs 24.08% (775/3 218); summer (June to August): 24.09% (121 867/505 839) vs 23.87% (768/3 218); fall (September to November): 26.69% (135 012/505 839) vs 25.08% (807/3 218); winter (December to next February): 24.95% (126 214/505 839) vs 26.97% (868/3 218)] (all P<0.05), but no significant difference was found in fetal gender ( P>0.05). Besides, gravidity [once: 49.32% (249 484/505 839) vs 47.02% (1 513/3 218); over twice: 50.68% (256 355/505 839) vs 52.98% (1 705/3 218)], parity [once: 73.60% (372 316/505 839) vs 77.07% (2 480/3 218); over twice: 26.40% (133 523/505 839) vs 22.93% (738/3 218)], history of stillbirth [0.33% (842/256 355) vs 0.65% (11/1 705)], hypertensive disorders in pregnancy [3.25% (16 464/505 839) vs 5.59% (180/3 218)], first trimester vaginal bleeding [2.02% (10 251/505 839) vs 2.61% (84/3 218)], placenta previa [0.98% (4 963/505 491) vs 2.64% (53/2 009)], and oligohydramnios [2.52% (12 764/505 839) vs 1.90% (61/3 218)] differed significantly between the two groups (all P<0.05). However, no significant difference was found between the two groups in terms of the proportion of women with gestational diabetes mellitus and previous spontaneous abortion (both P>0.05). After exclusion of fetal death in labor from the 3 218 stillbirths, the same results were achieved. Binary logistic regression analysis showed that women who were over 30 years old (30-35 years old: OR=1.42, 95% CI: 1.30-1.56; >35 years old: OR=2.59, 95% CI: 2.25-2.98), with a high school degree or below (middle school or below: OR=1.37, 95% CI: 1.21-1.55; high school: OR=1.28, 95% CI: 1.16-1.42), manual or freelance worker ( OR=1.18, 95% CI: 1.07-1.31), in the urban area ( OR=1.43, 95% CI:1.31-1.57), and gravidity ≥ 2 times ( OR=1.32, 95% CI: 1.21-1.43), primiparity ( OR=1.76, 95% CI: 1.58-1.96), gestational hypertension ( OR=2.80, 95% CI: 2.40-3.27), vaginal bleeding in the first trimester ( OR=1.35, 95% CI: 1.08-1.68), placenta previa ( OR=10.86, 95% CI: 8.84-13.35) and history of stillbirth ( OR=2.27, 95% CI: 1.30-3.98) were all risk factors of stillbirth. Conclusion:Pregnant women who were over 30 years old, less educated, manual worker or freelance or with a history of adverse pregnancy, vaginal bleeding in the first trimester, hypertension in pregnancy, and placenta previa are at higher risk of stillbirth
ABSTRACT
Objective:To investigate the incidence of delayed onset of lactogenesis Ⅱ (DOL Ⅱ) in mothers of preterm infants and its influencing factors.Methods:This retrospective cohort study involved women who delivered prematurely at the Department of Obstetrics of the First Affiliated Hospital of Zhengzhou University from September 2021 to March 2022. Demographic and perinatal data of the subjects were collected. According to lactation outcome on the third day after delivery, these women were divided into DOL Ⅱ and non-DOL Ⅱ groups. The two groups' differences in general conditions were compared, and the potential factors influencing DOL Ⅱ were also analyzed. Chi-square test, two independent samples t-test, Mann-Whitney U test, and logistic regression analysis were used for statistical analysis. Results:There were 286 mothers of premature infants enrolled in this study, and 73 (25.5%) of them experienced DOL Ⅱ. The other 213 cases without DOL Ⅱwere included as the non-DOL Ⅱ group. Univariate analysis showed significant differences between the DOL Ⅱ and non-DOL Ⅱ groups in the following aspects: the proportion of women with adverse pregnancy history [28.8% (21/73) vs 41.8% (89/213), χ2=3.89], the proportion of primiparas [60.3% (44/73) vs 38.0% (81/213), χ2=10.93], the incidence of hypertensive disorders of pregnancy [35.6% (26/73) vs 16.4% (35/213), χ2=11.92], the time to initiate breastfeeding after birth[5.0 h (3.0-7.0 h) vs 4.0 h (2.0-5.0 h), Z=－4.27], and the frequency of breastfeeding or pumping within 48 h after delivery [7.0 times (6.0-9.0 times) vs 9.0 times (7.0-11.0 times), Z=－3.62] (all P<0.05). Multivariate logistic regression showed that primipara ( OR=2.720, 95% CI: 1.485-4.982), hypertensive disorders of pregnancy ( OR=3.178, 95% CI: 1.609-6.274), the time to initiate breastfeeding ( OR=1.394, 95% CI: 1.211-1.604) and the frequency of breastfeeding/pumping within 48 h after delivery ( OR=0.861, 95% CI: 0.772-0.962) were independent influencing factors for DOL Ⅱ (all P<0.05). Conclusions:?The factors that influence the occurrence of DOL Ⅱ in preterm mothers are primipara hypertensive disorders of pregnancy, breastfeeding initiation time after delivery, and the frequency of breastfeeding or pumping within 48 h postpartum.
ABSTRACT
Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d<DOT≤15.0 d), Q 3 (15.0 d<DOT≤27.0 d) and Q 4 (DOT>27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%<breast milk intake ratio≤50%), medium-ratio breastfeeding group (50%<breast milk intake ratio≤75%) and high-ratio breastfeeding group (breast milk intake ratio>75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.
ABSTRACT
Objective:To investigate the reference ranges for thyroid function and its influencing factors in preterm infants at 14 d after birth.Methods:This retrospective study involved 514 preterm infants who met the inclusion criteria in Affiliated Hospital of Inner Mongolia Medical University from January 1, 2019 to December 31, 2021. They were divided into three group according to their gestational age [early premature group (26-31 +6 weeks, n=153), middle premature group (32-33 +6 weeks, n=129) and late premature group (34-36 +6 weeks, n=232)] or birth weight (BW) [<1 500 g group ( n=129), 1 500-2 000 g group ( n=120) and ≥2 000 g group ( n=265)]. Venous blood samples were collected from the infants at 14 d after birth and their thyroid function was determined by chemiluminescence immunoassay. The reference values of free triiodothyronine (FT 3), free thyroxine (FT 4) and thyroid stimulating hormone (TSH) were calculated based on the values of 95% confidence intervals ( CI) and expressed as percentiles in the range from P2.5 to P97.5. Mann-Whitney U test or Kruskal-Wallis H test was used to compare those thyroid hormone levels between groups. Spearman correlation analysis was used to study the correlation of gestational age or birth weight with FT 3, FT 4 and TSH levels. The factors influencing the levels of thyroid hormones were analyzed by multiple linear regression. Results:The reference ranges for FT 3, FT 4 and TSH were 1.53-3.72 pg/ml, 0.81-1.91 ng/dl and 1.32-7.80 μIU/ml in the early premature infants, 1.74-4.16 pg/ml, 0.90-2.82 ng/dl and 0.63-7.64 μIU/ml in middle prematures and 2.07-4.88 pg/ml, 1.09-2.27 ng/dl and 1.14-7.06 μIU/ml in late prematures. The reference ranges for the above three indexes were 1.53-4.06 pg/ml, 0.81-1.83 ng/dl and 1.14-7.84 μIU/ml in premature infants with BW<1 500 g, 1.67-3.98 pg/ml, 0.88-2.97 ng/dl and 0.94-7.64 μIU/ml in those whose BW between 1 500 g and 2 000 g and 1.91-4.75 pg/ml, 1.09-2.31 ng/dl and 1.14-6.32 μIU/ml in those whose BW≥2 000 g. Multiple linear regression showed that the level of FT 3 was positively correlated with gestational age ( β=0.119, P<0.05) and birth weight ( β=1.950×10 －4, P<0.05); that of FT 4 was positively correlated with gestational age only ( β=0.031, P<0.05); and TSH level was negatively correlated with birth weight ( β=－4.250×10 －4, P<0.05). Conclusions:Gestational age and birth weight are the factors influencing thyroid function in preterm infants at 14 d after birth. Evaluation of thyroid function with FT 4 and TSH should based on the references ranges of different gestational age and birth weight .
ABSTRACT
Administration of antenatal corticosteroids (ACS) to pregnant women at risk of preterm delivery can significantly reduce the incidence of preterm-related complications, such as respiratory distress syndrome and necrotizing enterocolitis. However, ACS may have adverse effects on multiple systems including nervous system, cardiovascular system and carbohydrate metabolism in preterm infants. Whether ACS could influence neonatal development is still controversial. On this account, this review, focusing on short- and long-term effects of ACS therapy on nervous, cardiovascular, endocrine and other systems of infants born prematurely, will help clinical management and scientific research.
ABSTRACT
Objective:To analyze the factors influencing the success rate of external cephalic version (ECV) and to create a preoperative scoring scale for stratified management of pregnant women who were preparing for ECV.Methods:This prospective study was conducted on singleton pregnant women who underwent ECV without anesthesia in Fujian Maternity and Child Health Hospital from January 1, 2017, to December 31, 2019. Univariate (two independent samples t-test, Mann-Whitney U test, and Chi-square test) and multivariate logistic regression were used to screen the clinical characteristics affecting the success of ECV, and receiver operating characteristic (ROC) curve was used to determine the cut-off value and convert quantitative variables into dichotomous variables. The independent variables were scored according to the regression coefficient in multivariate logistic regression analysis, and then a preoperative scoring scale was created. The ROC curve was used to calculate the cut-off value for the scoring scale. The subjects were divided into low and high score groups according to the cut-off value. The area under the ROC curve was used for evaluating the effectiveness of the scale in predicting the success of ECV. The success rate of ECV, difficulty of the operation and mode of delivery were compared between the two groups. Results:A total of 1 338 pregnant women met the inclusion criteria during the study period. After the exclusion of 885 women, 165 refused ECV in favor of direct cesarean section, 27 spontaneously converted to cephalic position before ECV, 261 who voluntarily accepted ECV were finally enrolled. ECV succeeded in 202 cases and failed in 59. (1) Favorable factors for ECV without anesthesia were the distance between the fetal breech and ischial spine <－3.5 cm ( OR=0.177, 95% CI: 0.071-0.438, P=0.009), the sum of the fundal height and the station of the fetal breech based on the ischial spine <30.25 cm ( OR=0.225, 95% CI: 0.094-0.537, P=0.001), amniotic fluid index ≥12 cm ( OR=0.399, 95% CI: 0.164-0.969, P=0.042), the surgeon's ability to hold the fetal head or breech with one hand ( OR=0.241, 95% CI: 0.098-0.589, P=0.002; OR=0.219, 95% CI: 0.087-0.546, P=0.001), and the fetal head located on the right or left upper abdomen of the mother ( OR=0.184, 95% CI: 0.059-0.568, P=0.003; OR=0.253, 95% CI: 0.084-0.760, P=0.014). (2) The area under the ROC curve of the preoperative score for predicting the success of ECV was 0.881 (95% CI: 0.821-0.941) and the cut-off value was 5.5. The subjects were divided into low (0-5 scores) and high (6-11 scores) score groups and the area under the ROC curve for predicting the success of ECV by grouping was 0.843 (95% CI: 0.774-0.912). Compared with the low score group, the high score group had a shorter ECV duration [2.0 min (0.5-10.0 min) vs 10.0 min (0.9-25.8 min), Z=－6.83, P<0.001], less attempts [1.0 times (1.0-4.0 times) vs 3.0 times (1.0-5.0 times), Z=－8.41, P<0.001], higher success rate [92.7% (190/205) vs 21.4% (12/56), χ2=127.64, P<0.001], higher rate of vaginal birth [75.4% (147/195) vs 18.5% (10/54)] and lower cesarean section rate [24.6% (48/195) vs 81.5% (44/54)] ( χ2=58.70, P<0.001). Conclusions:Preoperative scoring based on the factors influencing the success rate of ECV (the distance between the fetal breech and ischial spine, the sum of the fundal height and the station of the fetal breech based on the ischial spine <30.25 cm, amniotic fluid index ≥12 cm, the surgeon's ability to hold the fetal head or breech with one hand, and the fetal head locating on the right or left upper abdomen of the mother) is conducive to the individualized evaluation of the difficulty and the success rate of ECV as well as the success rate of vaginal delivery after ECV, which can provide a reference for clinical stratified management of ECV patients.
ABSTRACT
Objective:To investigate the clinical outcome after surgery and first 131I treatment in patients with moderate-risk papillary thyroid cancer (PTC), and analyze the relevant factors that affect the therapeutic effect. Methods:From January 2018 to April 2019, 135 patients (48 males, 87 females; age (42.7±11.1) years) with moderate-risk PTC in the Second Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. According to the 2015 American Thyroid Association (ATA) guidelines, patients were divided into excellent response (ER) group, inderteriminate response (IDR) group, biochemical incomplete response (BIR) group and structural incomplete response (SIR) group, of which IDR, BIR, SIR were collectively referred to as the non-ER group. χ2 test and Mann-Whitney U test were used to compare the general clinical features between the ER and non-ER groups, and then multivariate logistic regression analysis was performed. The predicted value of pre-ablation stimulated thyroglobulin (ps-Tg) to ER was assessed by ROC curve analysis. Results:The treatment responses of 94 patients were ER, and those of 41 were non-ER. The differences in tumor size (0.80(0.50, 1.10) vs 1.00(0.55, 1.50) cm; U=1 491.50, P=0.036), the number of metastatic lymph nodes (3(2, 5) vs 4(2, 12); U=1 422.00, P=0.015), metastatic lymph node size (0.50(0.30, 0.65) vs 0.50(0.30, 1.45) cm; U=1 396.50, P=0.013), metastatic lymph node involvement rate (50%(30%, 70%) vs 60%(50%, 85%); U=1 441.50, P=0.024), metastatic lymph node location (central/lateral: 76/18 vs 24/17; χ2=7.40, P=0.007) and ps-Tg level (2.1(0.8, 5.3) vs 14.0(3.2, 35.2) μg/L; U=680.00, P<0.001) were statistically significant between the ER and non-ER groups. Multivariate logistic regression analysis showed that ps-Tg (odds ratio ( OR)=1.200, 95% CI: 1.107-1.302, P<0.001) was an independent factor influencing ER. The cut-off value of ps-Tg for predicting ER was 7.38 μg/L, with the sensitivity and specificity of 68.3%(28/41) and 87.2%(82/94) respectively. Conclusion:Moderate-risk PTC patients with smaller tumor size, fewer metastatic lymph nodes, lower metastatic lymph node involvement rate, metastatic lymph nodes in central area, smaller metastatic lymph node size, and ps-Tg<7.38 μg/L have better therapeutic effect after initial 131I treatment.
ABSTRACT
It is difficult to maintain the initial posterior stability of the knee after posterior cruciate ligament reconstruction. Residual posterior knee laxity after operation is a problem of PCL reconstruction. It not only results in abnormal kinematics of the knee, but also leads to secondary meniscus injury and cartilage degeneration of the affected knee, and eventually leads to knee osteoarthritis, which may especially happen with persistent and severe posterior laxity. The main reasons of residual posterior knee laxity after PCL reconstruction are: improper treatment of the posterolateral corner injury, poor positioning of the femoral tunnel, small tibial slope, and unreasonable postoperative rehabilitation. There are some concepts and technologies, such as using artificial ligaments, tibial tunnel fixation with suspensory device or suspensory device combined with interference screws, enlargement of graft diameter, all-inside reconstruction combined suture augmentation, slow and gradual postoperative rehabilitation, which can eliminate or reduce the postoperative residual laxity, in order to improve clinical outcomes after PCL reconstruction. For the patients with flat tibial slopes, double-bundle PCL reconstruction and concurrent slope-increasing tibial osteotomy is suggested. It can reduce the risk of posterior laxity and improve the stability of the knee after operation.
ABSTRACT
Objective:To investigate the factors affecting postoperative short-term improvement of consciousness level in patients with prolonged disorders of consciousness after severe traumatic brain injury (sTBI).Methods:A case-control study was conducted to analyze the clinical data of 55 patients with prolonged disorders of consciousness after sTBI admitted to Beijing Tiantan Hospital Affiliated to Capital Medical University and Seventh Medical Center of PLA General Hospital from September 2021 to September 2022. There were 33 males and 22 females, with the age range of 13-68 years [(43.0±15.5)years]. All patients were assessed for the consciousness level using the coma recovery scale-revision (CRS-R) preoperatively and within 48 hours postoperatively. A total of 33 patients were observed in vegetative state and 22 in minimally conscious state preoperatively. The consciousness level was found to be improved in 26 patients (consciousness- improved group), but not improved in the remaining 29 patients (consciousness-unimproved group). Indicators were documented including gender, age, cause of injury, Glasgow coma score (GCS) on admission, course of injury, preoperative consciousness level, operation mode, operation time, intraoperative fluid replenishment, intraoperative urine volume, intraoperative bleeding volume, American Society of Anesthesiologists grade, analgesic regimen and sedation maintenance drugs. A univariate analysis was conducted first to assess those indicators′ correlation with postoperative short-term improvement of consciousness level in patients with prolonged disorders of consciousness after sTBI. Multivariate Logistic regression analysis was then used to determine the independent risk factors for their postoperative short-term improvement of consciousness level.Results:Univariate analysis showed that GCS on admission, course of injury, preoperative consciousness level and analgesic regimen were correlated with short-term improvement of postoperative consciousness level in patients with prolonged disorders of consciousness after sTBI (all P<0.05), whereas gender, age, cause of injury, operation mode, operation time, intraoperative fluid replenishment, intraoperative urine volume, intraoperative bleeding volume, American Society of Anesthesiologists grade and sedation maintenance drugs showed no relation to the improvement of postoperative consciousness level (all P>0.05). Multivariate Logistic regression analysis showed that the GCS ≥7 points on admission ( OR=0.06, 95% CI 0.01, 0.36, P<0.01), preoperative minimally conscious state ( OR=0.09, 95% CI 0.02, 0.40, P<0.01) and intraoperative use of Sufentanil combined with Remifentanil ( OR=0.07, 95% CI 0.01, 0.43, P<0.01) were significantly correlated with postoperative improvement of consciousness level. Conclusion:The GCS on admission (≥7 points), preoperative minimally conscious state and intraoperative use of Sufentanil combined with Remifentanil are independent risk factors affecting short-term postoperative improvement of consciousness level in patients with prolonged disorders of consciousness after sTBI.
ABSTRACT
Objective:To investigate the relationship between peripheral blood lipid levels and hepatitis B-related liver cancer, and to provide a theoretical basis for the early prevention and treatment of liver cancer.Methods:A total of 188 patients with hepatitis B-related liver cancer who received treatment in The First Hospital of Shanxi Medical University from June 2018 to June 2021 met the inclusion and exclusion criteria and had complete data, were included in this study. They were divided into three groups: chronic hepatitis B group ( n = 72), hepatitis B cirrhosis group ( n = 62), and hepatitis B-related liver cancer group ( n = 54) according to different stages of the disease. All patients' medical records were obtained from the medical data room. Fasting venous blood was collected in all patients on the second day after admission to detect peripheral blood lipid, liver function, and other relevant indicators. General data and biochemical indicators were collected. The Kruskal-Wallis test was performed to compare the measurement data among groups. The chi-squared test was performed to compare the count data among groups. Spearman's correlation (bivariate) was performed. Binary logistic regression was performed to analyze the influential factors of liver cancer. Results:There were significant differences in the levels of total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) among the three groups ( F = 32.14, 27.59, 10.88, 34.09, all P < 0.05). TC and LDL-C levels in the hepatitis B-related liver cancer group were significantly higher than those in the hepatitis B cirrhosis group ( F = -32.31, -50.19, both P < 0.05). There were no significant differences in TG and HDL-C levels between hepatitis B-related liver cancer and hepatitis B cirrhosis groups ( F = -10.69, 4.46, both P > 0.05). TC, TG, HDL-C and LDL-C levels in the hepatitis B cirrhosis group were significantly lower than those in the chronic hepatitis B group ( F = 53.30, 46.98, 24.61, 48.57, all P < 0.05). LDL-C level was positively correlated with the occurrence of liver cancer ( r = 0.20, P < 0.05). HDL-C level was negatively correlated with the occurrence of liver cancer ( r = -0.15, P < 0.05). LDL-C was an independent risk factor for liver cancer ( OR = 3.35, P < 0.05), and HDL-C was a protective factor for liver cancer ( OR = 0.12, P < 0.05). Conclusion:Compared with patients with chronic hepatitis B and hepatitis B cirrhosis, patients with hepatitis B-related liver cancer had abnormal peripheral blood lipid levels, which may be related to the abnormal lipid metabolism of tumor cells. Moreover, peripheral blood lipid levels may affect the occurrence and development of tumor cells.
ABSTRACT
Objective:To investigate the influential factors of adverse pregnancy outcomes in women with subchorionic hematoma.Methods:A total of 101 women with subchorionic hematoma who received treatment in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2017 to June 2020 were included in this study. They were divided into a control group and an adverse pregnancy outcome group according to whether there was an adverse pregnancy outcome. The epidemiological characteristics, hematoma characteristics observed on ultrasound images, and pregnancy outcomes were compared between the two groups.Results:There was no significant difference in the number of women who used assisted reproductive technology between the control and adverse pregnancy outcome groups [6 (8.0%) vs. 8 (30.7%), χ2 = 8.38, P = 0.004]. There was a significant difference in hematoma volume between adverse pregnancy outcome and control groups [(4.12 ± 0.61) mL vs. (6.36 ± 0.87) mL, t = 6.73, P = 0.009]. There was a significant difference in the number of patients who had obstetric complications between control and adverse pregnancy outcome groups [11 (14.7%) vs. 16 (61.5%), χ2 = 21.66, P = 0.001]. There was a significant difference in the number of patients who had hematomas located at the edge of the placenta between the control and adverse pregnancy outcome groups [15 (20.0%) vs. 12 (46.2%), χ2 = -4.81, P = 0.001]. Conclusion:Women who use assisted reproductive technology for pregnancy, have obstetric complications, or have a subchorionic hematoma with hematoma at the edge of the placenta are more likely to experience a miscarriage. Therefore, women of childbearing age should actively treat the primary disease and be alert to the occurrence of placental abruption.
ABSTRACT
Purpose: To present varied clinical presentations, surveillance reports, and final visual outcomes of a rare outbreak of cluster endophthalmitis caused by gram?negative, opportunistic bacilli, Burkholderia cepacia complex (Bcc). Methods: Details of five patients who developed postoperative cluster endophthalmitis were collected. For each patient, an undiluted vitreous sample was collected during vitreous tap. Bacterial culture from the vitreous sample in each case had grown Bcc. Surveillance investigations for root cause analysis (RCA) were performed in the operating room (OR), admission, and day?care wards to localize the source. Results: Four patients had undergone phacoemulsification surgery, and one patient had undergone penetrating keratoplasty. Each patient received an initial dose of empiric intravitreal ceftazidime and vancomycin. The organism isolated in each case was sensitive to ceftazidime, cotrimoxazole, and meropenem and resistant to other antibiotics. Core vitrectomy was done after 48–60 hours in four patients along with intravitreal imipenem injection. One patient did not provide consent for core vitrectomy and subsequently developed phthisis bulbi. Three patients had subsequent recurrences. Two patients had a final BCVA of 20/60, two had BCVA better than 20/200, while one patient had no perception of light. None of the surveillance samples from the OR complex could isolate Burkholderia. Conclusion: Extensive OR surveillance should be done to identify the potential source of infection. However, the source may not be identifiable in few instances like in our case. Longer follow?up is recommended in cases of Bcc endophthalmitis due to the persistent nature of the infection
ABSTRACT
Objective:To analyze the level of fractional exhaled nitric oxide (FeNO) and its influencing factors in patients with chronic obstructive pulmonary disease (COPD).Methods:678 patients with stable COPD(COPD group), 281 patients with asthma-COPD overlap(COPD with asthma group) and 120 healthy nonsmoker controls (healthy control group) were recruited from the outpatient clinics of Xiangya Second Hospital of Central South University and the 1st People′s Hospital of Huaihua from November 2016 to December 2021. The gender, smoking status, age, height, weight, body mass index (BMI), FEV 1% predicted value (FEV 1% pred), forced expiratory volume in 1 second/forced vital capacity (FEV 1/FVC%), and FeNO value among the three groups were compared. Multiple linear regression analysis was performed to analyze the influencing factors of FeNO levels in COPD patients. Results:There was no significant difference in gender, smoking status, age, height, weight and BMI among the three groups (all P>0.05). The FEV 1% and FEV 1/FVC% in COPD group were lower than those in healthy group and COPD combined with asthma group (all P<0.05). The FeNO in COPD group was lower than that in COPD and asthma group, but higher than that in healthy group (all P<0.05). Univariate analysis showed that FeNO levels in COPD patients were associated with height, BMI, Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) classification, and Chronic Obstructive Pulmonary Disease Assessment Test (CAT) score (all P<0.05). Multiple linear regression analysis showed that FeNO level was positively correlated with height ( β=0.094, P=0.014), CAT score ( β=0.129, P=0.001), and negatively correlated with BMI ( β=-0.093, P=0.016). There was no significant correlation between GOLD grading and FeNO level ( P>0.05). Conclusions:The level of FeNO in patients with COPD is higher than that in healthy subjects, which is related to height, BMI and CAT.
ABSTRACT
Objective:To investigate the influential factors of internal fixation for closed posterior ankle fractures.Methods:The clinical data of 352 patients with closed ankle fractures who received treatment in Yeda Hospital from January 2016 to June 2020 were retrospectively analyzed. Among the 352 patients, 232 patients had posterior ankle fractures. These patients were grouped according to whether they had undergone internal fixation. The factors that affect internal fixation for closed posterior ankle fractures were analyzed by univariate and multivariate analyses.Results:232 patients out of 352 patients with closed ankle fractures had closed posterior ankle fractures, accounting for 65.91%. A total of 102 (43.97%) patients with posterior ankle fractures underwent internal fixation. There were significant differences in Bartonicek classification, the proportion of the posterior subluxation of the talus, the proportion of posterior ankle bone area, the proportion of posterior ankle bone area ≥ 25% displayed on X-ray image, the proportion of posterior ankle bone area ≥ 15% displayed on CT scan, the proportion of outward displacement of bone mass (92.31% vs. 41.82%) and the proportion of die-punch bone mass (94.23% vs. 40.00%) between patients receiving and not receiving internal fixation ( χ2 = 3.89, 0.26, 1.51, 0.31, 9.27, 8.67, 1.68, 5.84, 10.33, 12.47, 11.48, 10.69, 1.39, all P < 0.05). Multivariate analysis of a logistic regression model showed that posterior subluxation of the talus and the proportion of posterior ankle bone area ≥ 15% displayed on CT scan were independent influential factors of internal fixation for closed posterior ankle fracture ( OR = 5.47, 9.29, 95% CI:1.62-9.75, 3.24-27.01, all P < 0.05). Conclusion:In patients with closed ankle fractures, posterior ankle fractures and internal fixation are more common. At the same time, the posterior subluxation of the talus and the proportion of posterior ankle bone area ≥ 15% displayed on CT scan are closely related to receiving internal fixation.
