目的 调查住院老年患者因经外周静脉置入中心静脉导管（PICC）而引发的血栓情况，并分析其影响因素，为老年患者置入PICC产生的相关性血栓（PICC-CRT）和症状性血栓的评估与干预提供借鉴。方法 在2023年1月—2023年12月期间，选取广州市第一人民医院接受PICC置管的317例住院老年患者。采用包括患者一般情况调查表、运动功能评定、肌力检测、 Barthel指数评定、Padua评分等多种工具进行综合评估。采用多因素 Logistic 回归构建 PICC-CRT 及症状性血栓的预测模型，并应用逐步回归法优化变量筛选过程。模型性能通过 ROC 曲线进行评估。结果 去除临床资料不完整的患者40例，最终纳入277例患者的完整资料，其中123例患者出现了PICC-CRT，发生率为44.40%（123/277）。血栓分级中，I级78例，Ⅱ级37例，Ⅲ级8例。无症状血栓83例，占67.48%，发生率29.96%（83/277）；症状性血栓40例，占32.52 %，发生率14.44%（40/277）。单因素分析联合多因素Logistic回归显示，卒中史、凝血酶原时间（PT）、导管留置时间是住院老年患者PICC-CRT的关键因素（P＜0.05），预测模型ROC曲线下面积为0.719；置管史、恶性肿瘤史、导管留置时间、置管后并发症数量是住院老年患者PICC症状性血栓的独立影响因素（P＜0.05），预测模型ROC曲线下面积为0.812。结论 文章总结了PICC-CRT和症状性血栓独特的影响因素，基于关键因素构建了预测模型预测其发生，为护理人员预防PICC-CRT和症状性血栓的发生提供了参考。

   Objective To explore the incidence of thrombosis associated with peripherally inserted central catheter（PICC）placement in hospitalized elderly patients and to analyze its influencing factors，in order to provide a reference for the assessment and prevention of PICC-catheter related thrombosis（PICC-CRT）and symptomatic thrombosis in this population．Methods A total of 317 elderly inpatients who underwent PICC placement at a tertiary hospital in Guangzhou between January and December 2023 were enrolled．Comprehensive assessments were conducted using general patient information forms，motor function evaluation，muscle strength testing，Barthel Index，and Padua score．Multivariate Logistic regression analysis was used to construct predictive models for PICC-CRT and symptomatic thrombosis，with variable selection optimized via stepwise regression．Model performance was evaluated using receiver operating characteristic（ROC）curve analysis．Results After excluding 40 patients with incomplete clinical data，277 cases were included in the final analysis．Among them，123 patients developed PICC-CRT，with an incidence rate of 44.40%（123/277）．Thrombosis was graded as Grade I in 78 cases，Grade II in 37 cases，and Grade III in 8 cases．Asymptomatic thrombosis occurred in 83 cases（29.96%），accounting for 67.48% of PICC-CRT；symptomatic thrombosis occurred in 40 cases（14.44%），accounting for 32.52%．Univariate and multivariate Logistic regression analyses identified history of stroke，prothrombin time（PT），and catheter dwell time as key risk factors for PICC-CRT（P＜0.05），with the area under the curve（AUC）of 0.719．History of catheterization，malignancy，catheter dwell time，and number of post-catheterization complications were independent predictors of symptomatic thrombosis（P＜0.05），with an AUC of 0.812．Conclusions This study identified distinct risk factors for PICC-CRT and symptomatic thrombosis in elderly inpatients．Predictive models based on key variables may provide useful references for clinical staff in preventing the occurrence of PICC-related and symptomatic thrombosis．

Objective To reveal the TORCH infection status and incidence of hospitalized newborns in Zunyi area, and provide important reference for early prevention and treatment of related diseases. Methods The retrospective research method was used to analyze the infection results of toxoplasma gondii (TOX), rubella virus (RV), cytomegalovirus (CMV) and herpes simplx virus (HSV) type I in hospitalized newborns in Zunyi Maternal and Child Health Hospital from 2018 to 2019. Results The overall positive rate of TORCH-IgM in 4 604 hospitalized newborns in Zunyi area was 1.35%, of which the positive rates of CMV, TOX, RV, and HSV Ⅰ were 1.00%, 0.20%, 0.13% and 0.02%, respectively; the corresponding TORCH-IgG positive rates were 67.38%, 0.91%, 54.54%, 22.22%. The TORCH infection screening results of neonates hospitalized in 2018—2019 showed that the CMV-IgM positive rate decreased from 1.47% to 0.43% (χ²=4.981, P=0.026), and the RV-IgM positive rate decreased from 0.24% to 0.00 (χ²=12.446, P< 0.001), the differences were statistically significant. In 2 607 male children, the IgM positive rates of CMV, TOX, RV and HSVⅠwere 0.19%, 0.11%, 0.96% and 0.04%, respectively; and the corresponding IgG positive rates were 1.07%, 55.20%, 67.93% and 22.48%. In 1 997 female children, the IgM positive rates of CMV, TOX, RV and HSVⅠwere 0.20%, 0.15%, 1.05% and 0.00,respectively; and the corresponding IgG positive rate was 0.70%, 53.68%, 66.65% and 21.88%. In the study of effects of different CMV-IgM infection on alanine aminotransferase(ALT) and aspartate aminotransferase(AST) activity, the ALT activity of CMV-IgM positive group was significantly higher than that of negative group (t=-2.793, P<0.05), and there was no difference in AST activity between the two groups (t=0.067, P>0.05). Conclusions The CMV infection rate among 4 604 hospitalized newborns in Zunyi area was relatively high, which should not be ignored. The recent infection rates of CMV and RV showed a downward trend from 2018 to 2019. CMV-IgM infection could cause an increase in ALT activity.

Methods Retrospective observational study including profile of discharged elderly in Nanhai hospital attached to Southern medical university from the year 2006 to 2014. Results In the top rank of diseases in hospitalized elderly, all were NCDs other than pneumonia and acute gastrointestinal diseases. The proportion of NCD accounted for all hospitalized elderly was reduced year by year, changed from 65.8% to 57.8%, P<0.01. Disease distribution of NCD altered obviously, showing that cerebrovascular disease (CVD) decreased from the first 21.3% to the second 17.0%, malignancy increased from 10.4% to 18.8% ranking as the first. Gender-differences did exist. Greater constituent ratio of chronic obstructive pulmonary disease (COPD) and malignancy were found in men than women yearly. NCD showed higher hospitalized expenses than non-NCD per capita, that of men were higher than women (P<0.05). Conclusion Summarizing the top and increasing rank of NCD and gender-differences in hospitalized elderly in a large comprehensive hospital, Nanhai district, Foshan city of 9 years, policy and program could be guided to optimize the distribution of medical resources and try to reduce the output of social economic burden.

Objective To investigate prevalence of nutritional risk, undernutrition, and nutritional support of hospitalized patients with non-tuberculosis mycobacteria. Methods Adult patients in Guangzhou Chest Hospital from October 2012 to October 2014 were enrolled by fix-point consecutive sampling. Nutritional Risk Screening 2002 (NRS2002) was performed and nutritional support was evaluated in all patients. Results A total of 402 patients were enrolled.Overall prevalence of undernutrition was 35.8%, and nutritional risk was 66.7%. Among all the patients, the rate of nutritional support was 60.0%, including 82.1%of patients with nutritional risk and 15.7% of non-risk patients. Gerontal patients, retreatment patients and female patients are in the greater possibility of being expose to nutritional risk or undernutrition. Conclusion A large proportion of inpatients with non-tuberculosis mycobacteria were at nutritional risk or undernutrition.The application of parenteral or enteral nutritional support currently maybe inappropriate. NRS2002 and parenteral or enteral nutrition guideline are required to affording nutritional support.
