Effect of the nurse-led program on blood glucose control and microalbuminuria development in type 2 diabetic populations.

Current study was to evaluate whether the nurse-led program can improve glycated hemoglobin (HbA1c) control and reduce the incidence of microalbuminuria in type 2 diabetic mellitus (DM2) populations. A total of 150 DM2 subjects were randomly assigned to the usual-care group and nurse-led program group. Study endpoints included the HbA1c value, the percentage of subjects with HbA1c < 7.0%, the incidence of microalbuminuria, and the rate of adhering to antidiabetic drug at 6 months' follow-up. At baseline, there was no difference in fasting plasma glucose, HbA1c, proportion of subjects with HbA1c < 7.0%, the use of antidiabetic drug, and urinary albumin-creatinine ratio between these two groups. After 6 months' follow-up, the mean fasting plasma glucose and HbA1c were lower in the nurse-led program group, as was the proportion of subjects with HbA1c < 7.0%. The median urinary albumin-creatinine ratio and rate of incident microalbuminuria were also lower in the nurse-led program. The nurse-led program was associated with higher odds of achieving HbA1c < 7.0% and a lower incidence of microalbuminuria. After adjusted for covariates, the nurse-led program was still associated with 32% higher odds of achieving HbA1c < 7.0% and 11% lower incidence of microalbuminuria. These benefits were consistent by sex and age, while greater in those with obesity or hypertension (P interaction < .05). The nurse-led program is beneficial for blood glucose control and prevention of microalbuminuria.

Prevalence and Factors Associated with BRCA1/2 Gene Mutation in Chinese Populations with Breast Cancer.

Objective: We aimed to evaluate the prevalence of BRCA1 and BRCA2 mutations in Chinese populations with breast cancer. Factors associated with BRCA1 and BRCA2 mutations are also evaluated. Methods: This was a cross-sectional study, and patients with breast cancer were included. Data on clinical characteristics, information of breast cancer, and BRCA1 and BRCA2 mutations were extracted. Patients were divided into the carrier and noncarrier groups. Results: A total of 368 patients were included. Compared to the noncarrier group (n = 240), patients in the carrier group (n = 128) were younger and more likely to have breast cancer at age <40 years. Of the overall 128 patients in the carrier groups, 58 had BRCA1 mutation and 70 had BRCA2 mutation. Among patients with early onset breast cancer, there was no difference in the prevalence of BRCA1 and BRCA2 (20.7% vs 17.1%, P = 0.35). While among patients with a family history of breast/ovarian cancer, BRCA2 mutation was more prevalent than BRCA1 mutation (54.3% vs 44.8%, P = 0.01); and among patients with triple-negative breast cancer, BRCA1 mutation was more prevalent than BRCA2 mutation (34.5% vs 28.6%, P = 0.04). After adjusting for covariates, factors associated with BRCA1 mutation included breast cancer diagnosed <40 years, tumor size >2 cm, and lymph node metastasis; and after adjusting for covariates, factors associated with BRCA2 mutation included age, tumor size >2 cm, and triple-negative breast cancer. Conclusion: The prevalence of BRCA1 and BRCA2 mutations varied according to three specific subgroups. Factors associated with BRCA1 and BRCA2 mutations were differential.

Association of total cholesterol and atherosclerotic cardiovascular disease in patients with follicular thyroid cancer: A real-world study from Chinese populations.

ABSTRACT: The association between serum total cholesterol (TC) level and incident atherosclerotic cardiovascular disease (ASCVD) in patients with follicular thyroid cancer postthyroidectomy is unknown.This was a retrospective study and patients (n = 384) were divided into low and high TC groups according to the median TC level. Incidence of composite ASCVD (myocardial infarction, ischemic stroke, and cardiovascular death) was compared between these 2 groups and factors contributing to the association of TC and ASCVD were evaluated.Patients in the high TC group were older and more likely to have diabetes and have higher C-reactive protein level. After thyroidectomy, serum levels of free triiodothyronine and free thyroxine were lower while thyroid-stimulating hormone level was higher in the high TC group. 31.6% and 39.7% of patients developed hypothyroidism in the low and high TC groups (P < .05) postthyroidectomy. The incidence rate of composite ASCVD was higher in the high TC versus low TC groups, with incidence rate ratio of 1.69 (95% confidence interval [CI]: 1.07-2.69), which was mainly driven by a higher incidence rate of myocardial infarction in the high TC group (incidence rate ratio: 2.11 and 95% CI: 1.10-4.20). In unadjusted model, higher TC was associated with 73% higher risk of composite ASCVD. After adjustment for hypothyroidism, the association of higher TC and composite ASCVD was attenuated into insignificance, with hazard ratio of 0.92 and 95% CI: 0.81 to 1.34.Increased TC level was associated with composite ASCVD, which might be attributed to hypothyroidism postthyroidectomy. The use of levothyroxine might help to prevent hypercholestemia and reduce the incidence of ASCVD.

Effectiveness of nurse-led program on mental health status and quality of life in patients with chronic heart failure.

Current study was to evaluate the effectiveness of nurse-led program in improving mental health status (MHS) and quality of life (QOL) in chronic heart failure (CHF) patients after an acute exacerbation. CHF patients were enrolled after informed consent was obtained and were assigned into the control and treatment group. Patients in the control group received standard care. In the treatment group, patients received standard care plus telehealth intervention including inquiring patients medical condition, providing feedbacks, counseling patients, and having positive and emotional talk with patients. At the third and sixth month after discharge, participants were called by registered nurses to assess Mental Health Inventory-5 (MHI-5) and Kansas City Cardiomyopathy Questionnaire (KCCQ) scores. Compared to the treatment group, patients in the control group were less likely to have educational attainment ≥ high school degree and have a married status, but were more likely to have diabetes. No significant differences in MHI-5 (68.5 ±â€Š12.7 vs 66.9 ±â€Š10.4) and KCCQ (70.6 ±â€Š12.2 vs 68.7 ±â€Š10.9) scores at baseline between the control and treatment groups were observed. There were significantly differences in MHI-5 (72.7 ±â€Š15.6 vs 65.2 ±â€Š11.4) and KCCQ score (74.2 ±â€Š14.9 vs 66.4 ±â€Š12.1) at 3 months follow-up between control and treatment groups. Nonetheless, at 6 months follow-up, although MHI-5 and KCCQ scores remained higher in the treatment group, there were no statistically significant differences (MHI-5: 65.4 ±â€Š12.8 vs 61.4 ±â€Š10.0; KCCQ: 65.1 ±â€Š12.3 vs 61.9 ±â€Š10.3). After multivariate regression analysis, not receiving nurse-led program were significantly associated with reduced MHI-5 (odds ratio [OR] 1.25% and 95% confidence interval [CI]: 1.14-1.60) and KCCQ (OR: 1.20% and 95% CI:1.11-1.54) scores. Nurse-led program is helpful to improve MHS and QOL in CHF patients after an acute exacerbation. However, these achievements are attenuated quickly after the nurse-led intervention discontinuation.

A signal peptide derived from Hsp60 induces protective cytotoxic T lymphocyte immunity against lymphoid malignancies independently of TAP and classical MHC-I.

Hsp60sp, a signal peptide derived from the leader sequence of heat shock protein 60 kDa (Hsp60), is a Qa-1/HLA-E-binding peptide. We previously showed that Hsp60sp-specific CD8+ T cells are involved in the immunoregulation of autoimmune diseases by controlling the response of self-reactive lymphocytes. Here, we report that Hsp60sp-specific CD8+ T cells killed malignant lymphocytes in vitro independently of transporter associated with antigen processing (TAP) and classical MHC-I expression. Induction of this cytotoxic T lymphocyte (CTL) response in vivo, either by adoptive transfer of in vitro-amplified CTLs or peptide-loaded dendritic cell immunization, resulted in effective control of lymphoid tumors, including TAP- or classical MHC-I-deficient cells. Hsp60sp-specific immune activation combined with programmed cell death protein 1 (PD-1) blocking synergistically restrained mouse lymphoma development. Importantly, Hsp60sp-specific CD8+ T cells did not negatively affect normal tissues and cells. Our data suggest that Hsp60sp-based immunotherapy is an inviting strategy to control lymphoid malignancies.

Predictive value of soluble ST-2 for changes of cardiac function and structure in breast cancer patients receiving chemotherapy.

The current study was to evaluate soluble ST-2 level and left ventricular ejection fraction (LVEF) in patients with breast cancer receiving doxorubicin or trastuzumab treatment for 6 months and determine whether soluble ST-2 level can be used to predictive left ventricular function impairment.Patients who were diagnosed as having breast cancer receiving doxorubicin or trastuzumab or combined therapy were enrolled. Demographic data, prior medical history and related medical therapy, and site and stage of breast cancer information were collected from electronic health record. Fasting blood was used to detect soluble ST-2 and brain natriuretic peptide (BNP) levels before and after 6 months doxorubicin or trastuzumab therapy. Echocardiography was performed before and after 6 months of doxorubicin or trastuzumab therapy.Participants were divided into 3 groups based on tertiary soluble ST-2 level. Compared with 1st tertiary group, patients in the 3rd tertiary group had higher proportion receiving combined therapy (14.3% vs 4.7%, P < .05). Baseline soluble ST-2 level was similar across groups. After 6 months' therapy, soluble ST-2 level was significantly higher in the 3rd tertiary group. Pearson correlation analysis showed that soluble ST-2 level was positively correlated with left ventricular volume and E/e' ratio while negatively correlated with LVEF. Doxorubicin, trastuzumab, combined therapy, soluble ST-2 level, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker treatment were all independently associated with LVEF change.In breast cancer patients receiving doxorubicin or trastuzumab therapy, soluble ST-2 level can be used to predict cardiac function and structure changes.
