Analysis of the status quo and influencing factors of family cancer communication among breast cancer patients / 中国实用护理杂志

Objective:To investigate and analyze the status quo of cancer communication in breast cancer patients′ families, so as to provide reference for targeted solutions to the communication problems of breast cancer patients' spouses.Methods:This was a cross-sectional study. From April to November 2022, 204 pairs of breast cancer patients and their spouses in Affiliated Hospital of Jining Medical College were taken as the research objects, and the basic information questionnaire, Family Avoidance of Communication about Cancer Scale (FACCS) and Female Self-Advocacyin Cancer Survivorship (FSACS) were used to investigate patients. The patient's spouse was investigated with Zarit Caregiyer Burden Interview (ZBI), and the survey data were statistically analyzed with hierarchical regression analysis.Results:The family cancer communication score of breast cancer patients was (65.30 ± 7.63) points. Hierarchical regression analysis showed that the patient′s Per capita monthly household income, tumor stage, family history of malignant tumor, and patient′s self advocacy level were the influencing factors of family cancer communication, which could explain 39.1% of family cancer communication variation ( F=22.36, P<0.05). From the aspect of patients′ spouses, the influence of spouse care burden could explain 14.2% of patients′ family cancer communication variation ( F=16.39, P<0.05). Conclusions:Breast cancer patients have poor family cancer communication. There are differences in the degree of family cancer communication among breast cancer patients with different characteristics. Patients with lower self-advocacy score, no previous family history of malignant tumor, higher spouse care burden, lower Per capita monthly household income and higher tumor stage have worse family cancer communication.

BGB-A445, a novel non-ligand-blocking agonistic anti-OX40 antibody, exhibits superior immune activation and antitumor effects in preclinical models / 医学前沿

OX40 is a costimulatory receptor that is expressed primarily on activated CD4+, CD8+, and regulatory T cells. The ligation of OX40 to its sole ligand OX40L potentiates T cell expansion, differentiation, and activation and also promotes dendritic cells to mature to enhance their cytokine production. Therefore, the use of agonistic anti-OX40 antibodies for cancer immunotherapy has gained great interest. However, most of the agonistic anti-OX40 antibodies in the clinic are OX40L-competitive and show limited efficacy. Here, we discovered that BGB-A445, a non-ligand-competitive agonistic anti-OX40 antibody currently under clinical investigation, induced optimal T cell activation without impairing dendritic cell function. In addition, BGB-A445 dose-dependently and significantly depleted regulatory T cells in vitro and in vivo via antibody-dependent cellular cytotoxicity. In the MC38 syngeneic model established in humanized OX40 knock-in mice, BGB-A445 demonstrated robust and dose-dependent antitumor efficacy, whereas the ligand-competitive anti-OX40 antibody showed antitumor efficacy characterized by a hook effect. Furthermore, BGB-A445 demonstrated a strong combination antitumor effect with an anti-PD-1 antibody. Taken together, our findings show that BGB-A445, which does not block OX40-OX40L interaction in contrast to clinical-stage anti-OX40 antibodies, shows superior immune-stimulating effects and antitumor efficacy and thus warrants further clinical investigation.

Imaging " mismatch" in acute ischemic stroke / 国际脑血管病杂志

Acute ischemic stroke has ischemic penumbra and actual infarct core, and when there is a bigger difference in the volume of the two, it is called " mismatch". It is not only manifested as a mismatch between the clinical manifestations and the infarct core, but also as a mismatch between the infarct core and the perfusion area. The advancement of neuroimaging technology enables this " mismatch" phenomenon to be manifested through different imaging methods or different sequences of the same imaging method, thereby providing more guidance for the further diagnosis and treatment process.

Analysis of prognostic factors for hospitalized patients aged 95 years and over with community-acquired pneumonia / 中华老年医学杂志

Objective To investigate clinical characteristics and prognostic factors for hospitalized patients aged 95 years and older with community-acquired pneumonia(CAP).Methods A retrospective study was conducted on CAP patients aged ≥95 years hospitalized in Jiangsu Province Hospital or Jiangsu Province Hospital of TCM between January 2014 and January 2018.Clinical characteristics were collected.The shock index (SI),Charlson comorbidity index (CCI),neutrophil/lymphocyte rate (NLR)and CURB-65 score were calculated.The predictive value of the related factors was evaluated by using the Logistic regression model and the subjects' receiver operating characteristic curve (ROC).Results A total of 205 cases were enrolled in this study.The hospital mortality rate was 36.1 ％ (73/205).The heart rate,white blood cell count,mononuclear cell count,neutrophil count (N),NLR,fasting blood glucose,blood urea nitrogen(BUN) and D-dimer results revealed significant differences between the death group and the survival group(all P＜0.05).Scores of CCI and CURB-65 were higher in the death group than in the survival group[(2.90 ±1.88) vs.(1.91 ± 1.81),(2.34 ±0.69)vs.(1.76±0.69),both P＜0.05].Multivariate Logistic analysis showed that heart rate≥84.73 beat per minute(OR =2.452,95％CI:1.054～5.702),NLR≥11.43(OR =5.499,95％CI:2.132～14.180),BUN≥12.95 mmol/L(OR =2.546,95％CI:1.025～6.319),CCI≥3(OR =4.453,95％CI:1.191～10.113),CURB-65≥2 scores(OR =3.888,95％CI..1.288～11.735)and respiratory failure (OR =2.875,95 ％CI:1.204～6.806)were risk factors for death in hospitalized elderly aged 95 years and older with CAP.ROC analysis showed that CCI combined with the CURB-65 score or CCI combined with the CURB-65 score plus NLR could better predict the in-hospital mortality of elderly patients than CCI or the CURB-65 score used alone.Conclusions Hospitalized patients aged≥95 with CAP are prone to multiple complications and high mortality rates.Combined application of multiple evaluation systems and indicators can improve the prognosis of outcomes for patients in this age group.

Analysis of related factors for clinical characteristics and the outcome in centenarian hospitalized patients / 中华老年医学杂志

Objective To investigate the health status of centenarian hospitalized patients and analyze the risk factors for in-hospital death in Nanjing district.Methods All centenarians hospitalized patients who were discharged from wards of 10 upper first-class general hospitals in Nanjing district during the past five years were retrieved from their hospital information systems.Then,a retrospective study was performed on centenarians' data of general information,laboratory test results,Charlson comorbidity index (CCI),neutrophil to lymphocyte ratio (NLR) and shock index(SI),etc.were calculated and collected.Relevant risk factors for in-hospital death were analyzed by multivariate logistic regression analysis.Results A total of 156 patients aged 100 years and over,with an average age of (101.0±2.1)years,were enrolled during the past 5 years.The top 3 admitting diagnosis for the patients were pulmonary infection(30.1％,47/156 cases),coronary heart disease(10.9％,17/156 cases)and cerebrovascular disease(7.1％,11/156 cases).Fifty patients died during hospitalization,with a mortality of 32.1％ (50/156).Pneumonia was the most common admitting diagnosis(40.0％,20/50 case).Among causes of death,the combined admitting diagnosis with dementia,chronic renal insufficiency,one or more basic disease were significantly associated with death.There were statistically significant differences between bad vs.good vs.indifferent prognosis in heart rate,shock index,leukocyte count,neutrophil count,NLR,hemoglobin,albumin,albumin/globulin,fasting blood glucose,blood urea nitrogen,serum creatinine,C-reactive protein(CRP)and CCI levels.Multivariate logistic regression analysis suggested that NLR≥13.18,fasting blood glucose ≥7.56 mmol/L,blood urea nitrogen ≥20.74 mmol/L,CRP≥65 mg/L and CCI≥3 might be predictors for in-hospital death in the cohort(OR =48.91、3.43、1.22、6.55、1.55,all P＜0.05).Conclusions Pulmonary infection is the most common reason for admission and the cause of death in centenarian inpatients.Comorbidities increase the risk of death.To lower in-hospital mortality,CCI and other assessment indicators should be used to strengthen the comprehensive assessment and chronic disease management of hospitalized centenarians.Infectious diseases should be prevented beforehand.

Objective To explore the effects of microRNA(miR)-1283 on invasion,proliferation and apoptosis of HTR 8/SVneo cell line derived from human-trophoblast cells.Methods HTR-8/SVneo cells were divided into three groups,as-miR 1283 group was transfected with miR 1283 analogues,anti-miR-1283 group was transfected with miR-1283 inhibitors,and negative control group was transfected with non functional sequence.The levels of miR 1283 expression were detected by fluorescence quantitative polymerase chain reaction at 24 hours after transfection.The cell proliferation was measured by 3-(4,5)-dimethylthiazol-2-yl-(2,5)-diphenyl tetrazolium bromide assay at 24,48 and 72 hours after transfection.Apoptosis was evaluated by propidium iodide staining and flow cytometry at 48 hours after transfection.Transwell experiments were performed to evaluate cellular invasion abilities at 24 hours after transfection.Analysis of variance and Bonferroni method were applied as statistical methods.Results The level of miR 1283 in as miR 1283 group was higher than that in the negative control group with statistically significant difference (14.85±0.57 vs 7.08±0.20,P＜0.01).At 24,48 and 72 hours after transfection,the inhibitory rate of cell proliferation in as-miR-1283 group was (8.04 ± 0.27) ％,(32.47 ± 0.24) ％ and (9.23± 0.17) ％,higher than those in the negative control group [(0.72 ± 0.06) ％,(1.17 ± 0.04) ％ and (0.53 ± 0.05) ％] (P ＜ 0.01,respectively).Cell apoptosis rate was higher in as-miR 1283 group than in negative control group [(16.33 ± 0.40) ％ vs (9.39± 0.58) ％,P＜0.01].The transmembrane cell number was lower in as-miR-1283 group as comparing with the negative control group (7.25 ± 1.83 vs 16.33 ± 2.08,P＜0.01).miR-1283 expression,apoptosis and transmembrane cell number in anti-miR-1283 group had no statistical difference as compared to the negative control group (all P ＞ 0.05).Conclusions Up-regulated levels of miR-1283 could inhibit HTR-8/SVneo cell proliferation and invasion,but promote the cell apoptosis.

Evaluation the significance of body mass index in diagnosing macrosomia in human neonate / 中华妇产科杂志

Objective We compared the difference of diagnosing macrosomia using the body mass index (BMI)and body mass,so as to investigate whether BMI play an important role in the diagnosis and management of macrosomia in our clinical work.Methods We analysed 5522 newborns (without any maternal complication)delivered in Shengjing Hospital of China Medical University from Jan.2004 to Apr.2009,all of them were full term,singleton and with the birth body mass larger than 2500 g,among them 4989 were in the group with body mass <4000 g,that was 2510-4000 g.533 cases were in the group of body mass ≥4000 g.By both body mass and length,we got the BMI.According to statistical receiver operating characteristic curve(ROC),we determined the cutoff of BMI for diagnosing macrosomia,in addition the sensitivity and specificity of it. Using this newly gotten BMI cutoff as a method to diagnose macrosomia and analyse the results.Results (1)When the newborns with birth length 40-43 cm.the mean birth body mass was(3010 ±351)g,BMI was(17.0 ±2.7)kg/m2;the newborns with birth length 48-51 cm,the mean birth body mass was(3450 ±313)g,BMI was(13.2±1.4)kg/m2;newborns with birth length 56-60 cm,the mean birth body mass was(4332 ±456)g,BMI was(12.5 ±1.3)kg/m2,The longer the birth length,the larger the birth body mass,while the less BMI.(2)Determined by ROC curve,the BMI value could be used to diagnose macrosomia was 14.2 kg/m2.with sensitivity of 78.4% and specificity of 85.0%, the area of under curve was 0. 892. (3) By the BMI cutoff ( 14. 2 kg/m2 ), 111 macorsomia with birth body mass ≥4000 g were not macrosomia any more (20. 8%, 111/533 ),422 still were macrosomia (79.2% ,422/533) ; while for those birth body mass <4000 g, 728 were macrosomia determined by this BMI cutoff ( 14. 59%, 728/4989 ), 4261 were still not macrosomia ( 85.41%, 4261/4989 ). Using BMI cutoff 14. 2 kg/m2 to diagnose macrosomia, within the group of birth body mass ≥4000 g, their birth length in macrosomia and non macrosomia was (52. 2 ± 1.8) cm and ( 55.6 ± 1.3 ) cm respectively, the difference was significant (P <0. 01 ) ;while within the group with body mass <4000 g, the birth length of macrosomia and non-macrosomia was (49.0 ±2. 2) cm and (50. 8 ±2. 2) cm respectively,the difference was significant as well (P <0. 01 ). The whole incidence of macrosomia was 20. 83% (1150/5522) determined by this BMI cutoff. Conclusions Birth body mass and BMI in determining macrosomia show some bias, and birth length relates with this difference, which suggests birth length maybe play an important role in determine the macrosomia. We suggest it is very necessary to use BMI≥ 14. 2 kg/m2 in the diagnosis and management of macrosomia.
