Objective Based on the intervention map to develop a comprehensive nutrition education program for pancreaticoduodenectomy patients and to explore the effect of its clinical application,aiming at providing references for clinical nursing practice.Methods A convenience sampling method was used to select 76 patients who were to undergo pancreaticoduodenectomy in the department of hepatobiliary and pancreatic surgery of a tertiary hospital in Anhui Province as the study subjects.The 38 patients admitted from October 2021 to September 2022 were in a control group,and the 38 patients admitted from October 2022 to July 2023 were in an experimental group.The experimental group received the comprehensive nutritional education programme constructed in this study,and the control group used conventional nutrition health education measures,and the length of intervention for both groups was from pre-hospitalization to discharge for 6 months.Nutrition-related indicators,postoperative complications,hospitalisation time,hospitalisation costs and satisfaction were compared between the 2 groups.Results A total of 64 patients completed this study,with 33 in the experimental group and 31 in the control group.Repeated measurement analysis of variance showed that the interaction effects of BMI,total serum protein and serum preprotein were statistically significant(P＜0.05).The incidence of complications,hospitalization days and hospitalization costs of the experimental group were lower than those of the control group(P＜0.05).The scores of nutrition education-related satisfaction in the experimental group were higher than those in the control group(P＜0.001).Conclusion A comprehensive nutritional education program based on intervention map can improve the nutritional status of pancreaticoduodenectomy patients to a certain extent,reduce the occurrence of complications,and promote patients'recovery.

Objective:To investigate the clinical application value of whole brain computed tomography perfusion(CTP)imaging combined with computed tomography angiography(CTA)on head and neck in treating chronic ischemic cerebrovascular disease(ICVD)by superficial temporal artery-middle cerebral artery(STA-MCA)bypass.Methods:Fifty patients with suspected chronic ICVD who admitted to Chengdu Second People's Hospital and Deyang People's Hospital(29 cases from Chengdu Second People's Hospital and 21 cases from Deyang People's Hospital)from May 2020 to October 2024 were selected.All patients underwent whole-brain CTP examination and CTA examination on head and neck before the surgery,and then,the preoperative assessment efficacy of the combination of the two examination for patients with STA-MCA surgical indication was analyzed.The changes of the CTP parameters[cerebral blood volume(CBV),cerebral blood flow(CBF),mean transit time(MTT),time to drain(TTD),and time to maximum(Tmax)]between the affected side and the healthy side before surgery,and between them after surgery,and these parameter of affected side between before and after surgery were compared respectively.The course and the anastomosis conditions of the bypass vessels were analyzed through CTA images.The CTP parameters of patients with postoperative cerebral hyperperfusion syndrome(CHS)were statistically analyzed.Then,the relationship between the changes of cerebral perfusion values on the affected side after surgery and CHS,as well as the follow-up situation,were analyzed.Results:In 50 patients with suspected chronic ICVD,34 patients with surgical indication of STA-MCA bypass were screened out by CTA combined with CTP,who existed severely narrowed or occluded blood vessels accompanied by reduced CTP,and other 16 cases who did not meet surgical indication of STA-MCA bypass were excluded.In 34 patients with chronic ICVD,the preoperative CBF value of affected side was lower than that of healthy side,and the preoperative MTT,TTD and Tmax values of affected side were all higher than those of the healthy side,and the differences were statistically significant(t=6.648,6.030,10.638,14.063,P<0.05),while there was not significant difference in CBV value between two sides(P>0.05).In the affected side,the postoperative CBF value was higher than preoperative CBF value,and the postoperative MTT,TTD and Tmax values were lower than preoperative these indicators,and the differences were statistically significant(t=8.578,7.166,11.321,11.912,P<0.05).There was no significant difference in the CBV value between before and after surgery(P>0.05).In 34 patients with chronic ICVD,there was not significant difference in CTP parameters between the affected side and the healthy side in 28 patients with chronic ICVD after 6 patients with CHS were excluded(P>0.05).The results of CTA showed that the diameter size and course of superficial temporal artery of all patients were clearly displayed,and the bypass vessels of them were unblocked,and the anastomoses of them were well developed.All 34 patients with chronic ICVD successfully completed unilateral STA-MCA bypass surgery.After the surgery,based on the clinical symptoms and the CTP reexamination results of the patients,it was determined that 6 patients(17.7%)were CHS,whose appearances were the CBF value of affected side was(60.81±5.79)ml/100(g·min),which was significantly higher than that[(53.30±5.21)ml/100(g·min)]of the healthy side.The MTT value of affected side was(2.9±0.82)s,which was significantly lower than that of the healthy side(4.2±1.1)s,and the differences were statistically significant(t=2.358,2.341,P<0.05).In the postoperative follow-up of 2 to 17 months for patients,there was not dead case,and the clinical symptoms of the most of patients were improved significantly,and there was no serious adverse events.Conclusion:Whole-brain CTP combined with CTA examination on head and neck is conducive to accurately determine the degree of vascular stenosis and cerebral perfusion before surgery,and screen patients with chronic ICVD who occurred indications of STA-MCA surgery,and can also assess the patency of bypass vessels,the recovery degree of cerebral perfusion,and the possibility of occurring CHS after surgery,which has important clinical guiding value.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Hepatocellular carcinoma(HCC)is a worldwide highly prevalent malignant tumor,and patients with advanced HCC often lose opportunity for surgery.The effect of TACE alone for treating advanced HCC is limited.Comprehensive treatment strategy,including TACE combined with ablation,hepatic arterial infusion chemotherapy,molecular targeted drugs and immune checkpoint inhibitors can promote tumor necrosis,reverse the immunosuppressive microenvironment and prolong patient's survival period through synergistic mechanisms.The research progresses of combination therapy strategy of TACE and other methods for advanced HCC were reviewed in this article.

Objective:To explore the design and implementation effectiveness of the course of Basic Geriatric Care Skills for undergraduate nursing students.Methods:The 496 undergraduate nursing students enrolled in 2019 at The First Affiliated Hospital of Chongqing Medical University were selected as the observation group, while 668 undergraduate nursing students enrolled in 2018 served as the control group. The control group received traditional teaching method, whereas the observation group was additionally provided with the course of Basic Geriatric Care Skills. The course was designed following the five steps of the ADDIE (analysis, design, development, implement, evaluation) model. The design was evaluated using the Delphi expert consultation method. Evaluation of teaching effectiveness included care skill assessment and performance evaluation. The overall evaluation of the course by students was collected through a questionnaire on the Superstar platform. SPSS 25.0 was used for χ2 test and independent samples t test. Results:The course consisted of 8 credit hours and was delivered through both online and offline approaches. The course included 4 modules with 20 care skills. The Cronbach's α values for the two rounds of expert consultation were 0.972 and 0.873, and the Kendall's W values were 0.124 ( χ2=61.38, P<0.05) and 0.260 ( χ2=128.83, P<0.001), respectively. The mean score of care skill assessment was 95.65±2.99 in the observation group and 94.16±3.52 in the control group, and the difference was statistically significant ( P<0.001). In performance evaluation, the highest-scoring dimension was teamwork (19.18±0.88), while the lowest was practical application (18.51±0.94). Questionnaire results indicated that 97.31% (289) of students found the course helpful in learning geriatric care, and 85.86% (255) of students deemed the course necessary. Conclusions:The course of Basic Geriatric Care Skills was well designed to meet the needs of students and to help improve their geriatric care skills.

Objective:To investigate the correlation between blood lipid levels and arterial stiffness in middle-aged and elderly Han Chinese individuals with angiotensin-converting enzyme(ACE)gene I/D polymorphism in Beijing.Methods:This was a cross-sectional study.The Han Chinese residents, aged 45 years and above, from Haidian District of Beijing, were recruited for the survey from May to August 2022.Based on the inclusion and exclusion criteria, 356 subjects were included, of which 100(28.09%)were male and 256(71.91%)were female.According to the population division criteria proposed by the World Health Organization, the subjects were divided into 253 cases in the middle-aged group[45-59 years old, median age 52.5(49.0, 56.0)years]and 103 cases in the elderly group[60-89 years old, median age 63.0(61.0, 65.0)years].Subjects were tested for ACE genotyping, lipids and brachial-ankle pulse wave velocity(baPWV).Lipid indices included triglyceride(TG), total cholesterol(TC), low density lipoprotein cholesterol(LDL-C)and high-density lipoprotein cholesterol(HDL-C).Results:In the middle-aged group, there were no significant differences in plasma levels of TC, TG and HDL-C between individuals with the DD genotype and those with the ID/Ⅱ genotype(all P>0.05).Similarly, in the elderly group, no significant differences were observed in plasma TC, TG, and HDL-C levels between individuals with the DD genotype and those with the ID/Ⅱ genotype(all P>0.05).In the middle-aged group, plasma LDL-C levels were significantly higher in the DD phenotype than in the ID/Ⅱ phenotype( Z=-2.483, P=0.013), while there was no significant difference in plasma LDL-C levels between the two phenotypes in the elderly group( Z=-0.935, P=0.350).There were no significant differences in baPWV between the DD and ID/Ⅱ phenotypes in both the middle-aged and elderly groups( Z=-0.104, -1.490, P=0.917, 0.136).In the elderly group, plasma TG levels were positively correlated with baPWV in the DD phenotype( r=0.590, P=0.016).In the middle-aged group, plasma TG levels were positively correlated with baPWV in the ID/Ⅱ phenotype( r=0.158, P=0.019), while plasma HDL-C levels were negatively correlated with baPWV( r=-0.174, P=0.009). Conclusions:Among middle-aged and elderly individuals with different ACE gene I/D polymorphisms, there are differences in blood lipid indicators sensitive to arterial stiffness.For middle-aged individuals with the ID/Ⅱ phenotype, arterial stiffness is more sensitive to high TG and low HDL-C levels, whereas for elderly individuals with the DD phenotype, arterial stiffness is more sensitive to high TG levels.These findings offer an experimental foundation for tailored blood lipid management strategies across diverse populations, aiming to maintain cardiovascular health and reduce the occurrence of cardiovascular diseases.

Objective To explore the impact of irregular shape of head CT hematomas on postoperative re-bleeding and prognosis of patients with spontaneous intracerebral hemorrhage(ICH)who undergo craniotomy for hematoma evacuation.Methods We retrospectively enrolled consecutive patients with ICH who underwent craniotomy for hematoma evacuation in the Department of Neurosurgery of the Second People's Hospital of Guiyang Affiliated to Guizhou Medical University from January 2019 to June 2024.Baseline and clinical data were collected form the patients,including age,gender,smoking history,drinking history,hypertension,diabetes,history of anticoagulant use,admission systolic and diastolic blood pressure,admission National Institutes of Health stroke scale(NIHSS)score,Glasgow coma scale(GCS)score,time from onset to the first head CT,neutrophil-to-lymphocyte ratio(NLR),and platelet-to-lymphocyte ratio(PLR).Admission head CT scans were used to assess hematoma shape(regular or irregular),hematoma location(basal ganglia,lobar,multifocal),hematoma volume,perihematomal edema volume,the presence of midline shift,and intraventricular extension.Volume of the hematoma was assessed 2 days after surgery.Postoperative re-bleeding is defined as an increase in the volume of the hematoma by 12.5 ml compared to the previous postoperative CT scan within 2 weeks after surgery,or the reappearance of high-density areas in the focal area of the head CT scan during follow-up after complete hematoma clearance.Conduct patients follow-ups via telephone at 6 months postoperatively to assess their modified Rankin scale(mRS)scores.The sliding dichotomy method was applied to define prognosis based on the patients' baseline characteristics and disease severity.The prognostic score was calculated using formula:10 × admission GCS score-age-0.64 × admission hematoma volume.A prognostic score＞27.672 was considered potentially favorable,while a score ≤ 27.672 was considered potentially unfavorable.For patients with a potentially favorable prognosis,an mRS score of 0-2 was defined as a good outcome,and a score of 3-6 as a poor outcome.For those with a potentially unfavorable prognosis,an mRS score of 0-3 was defined as a good outcome,and a score of 4-6 as a poor outcome.In the comparison of baseline and clinical data between patients with regular and irregular hematoma shapes,factors with P＜0.05 were included in propensity score matching(PSM)to adjust for confounding variables.A 1∶1 matching was performed using the nearest neighbor method with a caliper value set to 0.25.Variables with statistically significant differences between groups after PSM matching were included in the multivariate Logistic regression analysis to identify influencing factors for postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy hematoma evacuation.The predictive value of irregular hematoma shape for postoperative rebleeding and poor prognosis in ICH patients was analyzed using receiver operating characteristic(ROC)curve analysis.Results(1)A total of 440 ICH patients were enrolled,including 342 males and 98 females,aged from 20 to 84 years with a mean age of(56±12)years.Statistically significant differences were observed in baseline and clinical data between patients with regular and irregular hematoma shapes before PSM,including age,admission GCS score,NIHSS score,NLR,proportion of patients with hematoma rupture into ventricles,preoperative hematoma volume,proportion of patients with midline shift,preoperative volume of hematoma surrounding edema,proportion of patients with hematoma located in multiple sites,and postoperative 2-day hematoma volume(all P＜0.05).After propensity score matching of these factors,298 ICH patients were included in the statistical analysis,comprising 228 males and 70 females,with an age range of 20 to 84 years and a mean age of(57±12)years.Following PSM,no statistically significant differences were observed in the baseline and clinical characteristics between patients with irregular and regular hematoma shapes(all P＞0.05).(2)After propensity score matching,28 patients experienced postoperative re-bleeding while 270 did not.Significant differences were observed between the two groups in the following factors:proportion of patients with a history of anticoagulant use,admission PLR,NLR,irregular hematoma shape,and hematoma volume at 2 days after operation(all P＜0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P＞0.05).Using postoperative re-bleeding as the dependent variable and incorporating factors with P＜0.05 from the univariate analysis as independent variables,multivariate Logistic regression analysis identified irregular hematoma shape(OR,2.821,95％CI 1.142-6.968,P=0.025)and larger hematoma volume at 2 days post-operation(OR,1.062,95％CI 1.026-1.099,P＜0.01)as independent risk factors for re-bleeding following intracranial hematoma evacuation in ICH patients.ROC curve analysis demonstrated that irregular hematoma shape predicted postoperative re-bleeding with an area under the curve(AUC)of 0.62,showing a sensitivity of 71.4％and a specificity of 52.2％.(3)After propensity score matching,174 patients had poor prognosis while 124 had good prognosis.Significant intergroup differences were observed in age,admission GCS score,NIHSS score,irregular hematoma shape,proportion of patients with hematomas located in the basal ganglia and cerebral lobes,and hematoma volume at 2 days post-operation(all P＜0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P＞0.05).Using poor prognosis as the dependent variable and incorporating factors with P＜0.05 from univariate analysis as independent variables,multivariate Logistic regression analysis revealed that advanced age(OR,1.039,95％CI 1.015-1.064,P=0.002),high admission NIHSS score(OR,1.068,95％CI 1.025-1.113,P=0.002),irregular hematoma shape(OR,2.675,95％CI 1.582-4.524,P＜0.01),and larger hematoma volume at 2 days post-operation(OR,1.033,95％CI 1.002-1.064,P=0.038)were independent risk factors for poor prognosis.Conversely,lobar hematoma location(OR,0.192,95％CI 0.073-0.504,P＜0.01)was identified as a protective factor.ROC curve analysis showed that irregular hematoma shape predicted poor prognosis after intracranial hematoma evacuation with an AUC of 0.61,demonstrating a sensitivity of 59.2％and specificity of 62.9％.Conclusion Irregular hematoma shape on head CT is an independent risk factor for both postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy for hematoma evacuation.

Iodine is an indispensable trace element in the human body and its intake level is closely related to thyroid function. Iodine deficiency or iodine excess will lead to iodine-related diseases. The implementation of the universal salt iodization policy of China has achieved remarkable results, yet it is still facing the problems of iodine deficiency and iodine excess at present. Since iodine in the human body is mainly metabolized by the kidneys and excreted in urine, urinary iodine test has become an effective way to reflect the recent iodine nutrition status of the body. This article will discuss the current iodine nutrition status of the population in China, the hazards of iodine deficiency and iodine excess, as well as the clinical application of urinary iodine test.

With the improvement of diagnosis and treatment level, most breast cancer patients survive in a chronic state for a long time, and the issue of concomitant diseases of breast cancer (CDBC) has become increasingly prominent. All-round and full-cycle management of these comorbidities can help improve patients’ quality of life and prognosis. General practice, with its long-term, comprehensive and responsible health care that is person-centered, family-based, community-wide and oriented to the maintenance and promotion of overall health, presents new opportunities for the health management of CDBC. This article will explore the application of consultation-liaison general practice through the integrated general and specialist care in the comprehensive management of CDBC, aiming to raise people’s awareness of it and promote the development of consultation-liaison general practice and the management model of the "Internet plus general practitioner team" , which will surely contribute to the all-round management of concomitant diseases in breast cancer patients.

Parathyromegaly refers to chronic enlargement of the parathyroid glands caused by multiple etiological factors. Pathological conditions, such as hyperparathyroidism, parathyroid hyperfunction, parathyroid adenoma, parathyroid cysts, and parathyroid carcinoma may all lead to parathyromegaly. Notably, calcium intake insufficiency and/or vitamin D insufficiency (CVI), which is the predominant etiology of parathyromegaly, now has been recognized as a global public health challenge. Chronic CVI induces negative calcium balance and relative low serum calcium level, stimulating compensatory parathyroid hyperplasia and enlargement. This progression triggers parathyroid hyperfunction and secondary hyperparathyroidism, resulting in bone mass loss, height reduction, kyphosis, osteoporosis, pathological fractures, metastatic vascular calcification and systemic abnormal calcium migration and calcinosis (such as urolithiasis). During the early stages of parathyromegaly, the condition remains preventable and treatable; However, delayed intervention may lead to irreversible tertiary hyperparathyroidism. CVI-associated parathyromegaly exhibits high prevalence and heterogeneous clinical manifestations, representing a critically underrecognized clinical entity. This article will systematically discuss the etiology, pathological characteristics, clinical consequences, and prevention and control strategies for CVI-related parathyromegaly.
