Changes in Plant-Based Diet Indices and Subsequent Risk of Type 2 Diabetes in Women and Men: Three U.S. Prospective Cohorts

OBJECTIVEWe evaluated the associations between changes in plant-based diets and subsequent risk of type 2 diabetes.RESEARCH DESIGN AND METHODSWe prospectively followed 76,530 women in the Nurses’ Health Study (NHS) (1986–2012), 81,569 women in NHS II (1991–2017), and 34,468 men in the Health Professionals Follow-up Study (1986–2016). Adherence to plant-based diets was assessed every 4 years with the overall plant-based diet index (PDI), healthful PDI (hPDI), and unhealthful PDI (uPDI). We used multivariable Cox proportional hazards models to estimate hazard ratios (HRs). We pooled results of the three cohorts using meta-analysis.RESULTSWe documented 12,627 cases of type 2 diabetes during 2,955,350 person-years of follow-up. After adjustment for initial BMI and initial and 4-year changes in alcohol intake, smoking, physical activity, and other factors, compared with participants whose indices remained relatively stable (±3%), participants with the largest decrease (>10%) in PDI and hPDI over 4 years had a 12–23% higher diabetes risk in the subsequent 4 years (pooled HR, PDI 1.12 [95% CI 1.05, 1.20], hPDI 1.23 [1.16, 1.31]). Each 10% increment in PDI and hPDI over 4 years was associated with a 7–9% lower risk (PDI 0.93 [0.91, 0.95], hPDI 0.91 [0.87, 0.95]). Changes in uPDI were not associated with diabetes risk. Weight changes accounted for 6.0–35.6% of the associations between changes in PDI and hPDI and diabetes risk.CONCLUSIONSImproving adherence to overall and healthful plant-based diets was associated with a lower risk of type 2 diabetes, whereas decreased adherence to such diets was associated with a higher risk.     

Adherence to Mediterranean diet and patient perception of rheumatoid arthritis

ObjectiveTo evaluate the association between the adherence to Mediterranean diet (MD) and disease impact, activity, and comorbidities in patients with rheumatoid arthritis (RA).DesignConsecutive patients with RA were enrolled in this cross-sectional study. For each patient, Disease Activity Score on 28 joints (DAS28), Simple Disease Activity Index (SDAI), RA Impact of Disease (RAID), Health Assessment Questionnaire (HAQ), patient global assessment (PGA) and general health (GH) and a self-reported questionnaire called MD score were recorded.Results205 RA patients (median age 53 years, female 80.49 %) were enrolled. An association between MD score and HAQ (p-value = 0.033), PGA and GH (p-value 0.023 both) was observed. RAID total score had a statistically significant negative relationship with MD score (p-value = 0.016). A statistically significant negative association was found for pain (p-value = 0.025), functional disability (p-value<0.001), sleep (p-value = 0.041), physical well-being (p-value = 0.027) and coping (p-value = 0.008). Multiple regression analysis to evaluate the relationship between significant RAID items and MD score did not show any statistical significance as all items are strongly related to each other. A negative trend, although not statistically significant was found for DAS28 and SDAI. The only comorbidity associated with MD score was arterial hypertension (OR = 0.94).ConclusionsIn this Italian RA cohort, the adherence to MD was significantly associated with a better RAID, PGA and GH, but higher MD score was not significantly associated with lower disease activity. Our study suggests an overall potential beneficial effect of MD in RA patients.     

Plant-Based Diets and All-cause and Cardiovascular Mortality in a Nationwide Cohort in Spain: The ENRICA Study

ObjectiveTo investigate the associations of a healthful plant-based diet index (hPDI) and an unhealthful plant-based diet index (uPDI) with all-cause and cardiovascular disease (CVD) mortality in Spanish adults.Patients and MethodsWe analyzed data from 11,825 individuals 18 years of age or older, representative of the Spanish population, recruited between 2008 and 2010 and followed-up to 2020. Food consumption was collected at baseline using a validated dietary history, which served to calculate two plant-based diet indices based on 18 major food groups (range, 18-90 points). For (1) hPDI only the consumption of healthy plant foods (whole grains, fruits, vegetables, nuts, legumes, vegetable oils, and tea/coffee) received positive scores; whereas for (2) uPDI, only the consumption of less healthy plant foods (fruit juices, sugar-sweetened beverages, refined grains, potatoes, and sweets/desserts) received positive scores. Multivariable-adjusted Cox models were used to estimate HRs and their 95% CIs.ResultsAfter a median follow-up of 10.9 and 9.8 years, 699 all-cause and 157 CVD deaths were ascertained, respectively. Each 10-point increase in hPDI was associated with 14% lower risk of all-cause death (HR, 0.86; 95% CI, 0.74 to 0.99), and 37% lower risk of CVD death (HR, 0.63; 95% CI, 0.46 to 0.85). No significant associations were found for uPDI.ConclusionHigher adherence to an hPDI diet, but not to a uPDI, was associated with lower all-cause and CVD mortality. This suggests that the quality of the plant food consumed is paramount to achieve diet-related benefits in mortality.Trial registrationclinicaltrials.gov Identifier: NCT02804672     

Usefulness of four surrogate indexes of insulin resistance in middle-aged population in Hefei,China

ObjectivePrevious study have shown that lipid accumulation product (LAP), visceral adiposity index (VAI), triglyceride/high-density lipoprotein cholesterol ratio (TG/HDL-C) and triglycerides/glucose index (TyG index) could be simple clinical indicators of insulin resistance (IR) based on anthropometric and/or biochemical parameters. However, the rational and preferred surrogate marker of IR in different population has yet to be validated. The aim of this study was evaluating the practicability of the LAP, VAI, TG/HDL-C, and TyG in predicting IR in middle-aged Chinese population.MethodsA cross-sectional study was conducted in 569 Chinese participants (mean age was 48.5; man 67.7%), and each participant completed a questionnaire survey, anthropometric measurement, and biochemical testing. One-way ANOVAs, Chi-squared test, Pearson’s correlation, and multiple logistic regression were used to evaluate the association between VAI, LAP, TG/HDL-C, and TyG with IR. To correctly discriminate individuals with insulin resistance, a receiver operating characteristic (ROC) analysis was conducted for each evaluated variable and the overall diagnostic accuracy was quantified using the area under the ROC curve (AUC). The AUC of evaluated variables were compared using a nonparametric approach. The optimal cut-off points were determined by the Youden’s index, and the corresponding sensitivity and specificity were provided.ResultsSignificant positive correlation was identified between HOMA-IR with TG/HDL-C (r = 0.306), VAI (r = 0.217), LAP (r = 0.381), and TyG (r = 0.371), respectively (all p < .001). After adjustment for potential confounders of IR, compared with the lowest tertiles, odds ratio (95% CI) having IR in the highest tertiles of TG/HDL-C, VAI, LAP and TyG were 6.07 (2.89–12.71), 10.89 (4.37–27.13), 4.68 (2.00–10.92), and 12.20 (5.04–29.56). The area under ROC curves to predict HOMA-diagnosed IR was 0.773 for TG/HDL-C, 0.767 for VAI, 0.806 for LAP, and 0.800 for TyG, respectively. Among those, LAP showed the greatest value of AUC [0.806 (0.763–0.850)] and highest specificity (0.804).ConclusionCompared with other indicators, the LAP and TyG are simple, relatively accurate, clinically available surrogate markers of insulin resistance in middle-aged population in Hefei, China. Among 4 evaluated parameters, the LAP have the highest specificity and the TyG have the highest sensitivity.

Key Messages

• LAP and TyG could be used as simple and alternative methods to identify the individuals at risk for insulin resistance.
• LAP and TyG have relatively high predictive ability in diagnosis of IR compared with VAI and TG/HDL-C.
• No significant difference is observed between LAP and TyG in the ability of predicting insulin resistance.

     

Comparing the sub-gingival levels of Cytomegalovirus,Epstein-Barr virus,Porphyromonas gingivalis in human immunodeficiency virus-1 seropositive patients with and without antiretroviral therapy

ObjectivesThe effect of antiretroviral therapy (ART) on the oral pathogenic microbes in human immunodeficiency virus-1 seropositive patients remains relatively unexplored. Thus, the present study assessed the effect of ART on the sub-gingival levels of 3 pathogenic microbes.Materials and MethodsThe study groups consisted of 60 human immunodeficiency virus-1 seropositive patients divided into 3 groups of 20 each. Group 1 had periodontitis and did not start with the ART. Group 2 had periodontitis and started with ART (Tenofovir Disoproxil Fumarate 300 mg + Lamivudine 300 mg + Efavirenz 600 mg) at least 6 months before the study. Group 3 with normal periodontium, and have not started ART. The sub-gingival loads of Cytomegalovirus, Epstein-Barr virus, and the Porphyromonas gingivalis levels were assessed, along with the CD4 counts.ResultsThe cytomegalovirus load was highest in group 1, followed by groups 2, and 3 (p-value of 0.271). The Epstein-Barr load was highest for group 2, followed by group 3, and 1 (p-value of 0.022). The P.gingivalis load was highest in group 2, followed by groups 1 and 3, (p-value of 0.028). The Epstein-Barr and Cytomegalovirus counts were significantly higher (p-value < 0.02) when the CD4 counts were less than 500 cells/cu3.ConclusionART did not cause any significant reduction in the sub-gingival levels of any of the 3 examined microbes. Given the lack of any significant effect on the sub-gingival microbial loads by the ART, human immunodeficiency virus patients may require additional anti-microbial agents and regular mechanical plaque removal to maintain their periodontal status.     

Low-Fidelity,In-Situ Pediatric Resuscitation Simulation Improves RN Competence and Self-Efficacy

ProblemED staff lack adequate exposure to critical pediatric patients to develop competence and confidence in resuscitation scenarios. Simulations of various designs have shown success at increasing health care staff performance and self-efficacy.MethodsWe developed a nurse-led, low-fidelity in situ simulation of a pediatric sepsis scenario. The primary goal was to improve staff adherence to resuscitation guidelines, as measured by the Clinical Performance Tool, a set of checklists designed to measure adherence to Pediatric Advanced Life Support algorithms by multidisciplinary teams during simulations. The secondary goal was to improve staff confidence, measured by the Confidence Scale, a 5-item Likert-type scale that can measure any psychomotor skill.ResultsA total of 43 RNs participated in 12 simulations over a period of 3 months. Mean Clinical Performance score improved by 74%, from 5.3 to 9.2 (P < 0.001). Mean confidence score for RNs improved by 56%, from 2.48 (standard deviation [SD] 0.83) to 3.88 (SD 0.66) (P < 0.001). Several systems issues were identified and addressed by multidisciplinary teams, such as increasing respiratory therapist response to the emergency department and updating of the Broselow cart.DiscussionIn situ low-fidelity simulations led by RNs contributed to significant improvement in adherence to resuscitation guidelines and in staff confidence. The simulation design had minimal impact on staffing and budget and enabled identification and correction of systems issues.

Plasma apelin levels,blood pressure and cardiovascular risk factors in a coastal Chinese population

Abstract

Objectives. To describe the relationship of plasma apelin levels with blood pressure in a coastal Chinese population.

Methods. This cross-sectional study included a total of 1031 subjects from the coastal areas of China. One-way analysis of variance (ANOVA) and linear trend test, Pearson's correlation analysis, as well as multivariate linear regression analysis were used to evaluate the association between plasma apelin levels and blood pressure.

Results. Plasma apelin levels dropped with increasing quartiles of systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial blood pressure (MABP) (all P < 0.001). SBP, DBP, and MABP values decreased as the apelin levels increased within the quartiles. After adjusting for age and gender, the significant differences in SBP, DBP, and MABP between the groups within the apelin quartiles remained (all P < 0.05). A significant negative correlation between SBP, DBP, as well as MABP and apelin levels was observed (all P < 0.01); even after adjusting for cardiovascular confounding factors, this negative correlation remained (all P < 0.001).

Conclusion. A negative correlation between plasma apelin levels and blood pressure was found in this 1000-population-based epidemiological study. Apelin may become a potential therapeutic target of anti-hypertensive treatment.     

Assessment of glufosinate-containing herbicide exposure: A multi-center retrospective study

BackgroundExposure to glufosinate ammonium, an herbicide used worldwide, can cause CNS and respiratory toxicities. This study aimed to analyze acute human glufosinate ammonium poisoning.Materials and methodsThis multicenter retrospective cohort study involved five medical institutes affiliated with the Chang Gung Memorial Hospital system. Patients with glufosinate ammonium exposure visiting the emergency department (ED) between January 2008 and December 2020 were included.ResultsIn total, 95 patients were enrolled. Compared to exposure via the non-oral route, patients exposed orally (n = 61) had lower GCS scores, higher mortality rates, and longer hospital lengths of stay (P-value: <0.001, 0.002, and < 0.001, respectively). In the subgroup analysis among oral exposure patients, the survival group had a lower amount of estimated glufosinate ingestion than the non-survival group (10.5 [3.4–27] vs. 40.5 [27–47.3] g, P-value: 0.022), lower rate of substance co-exposure (9 [19.6%] vs. 10 [66.7%] P-value: 0.001), and lower rate of paraquat co-exposure (0 [0%] vs. 7 [46.7%] P < 0.001) compared with the mortality group. In the orally-exposed and non-paraquat co-exposure patients (n = 54), age > 70 years and GCS score < 9 at triage presented a high sensitivity (100.00%, 95% CI: 63.06–100.00%) and medium specificity (58.70%, 95% CI: 43.23–73.00%) in predicting mortality.ConclusionOld age, change in consciousness, and paraquat co-exposure were associated with higher mortality in human glufosinate poisoning. Age > 70 years and GCS score < 9 at triage could be predictors of mortality in patients with acute oral glufosinate poisoning.     

Efficacy of a topical formulation of henna (Lawsonia inermis L.) in contact dermatitis in patients using prosthesis: A double-blind randomized placebo-controlled clinical trial

BackgroundContact dermatitis is a common complication in prosthetic limb users. There are no effective, available and cheap treatments for skin problems of these patients. In traditional Iranian medicine, henna (Lawsonia inermis L.) is a plant that has anti-inflammatory, antimicrobial and skin-enhancing properties, all of which are beneficial for people with artificial limbs. The aim of this study was to assess the efficacy of a topical henna preparation in management of contact dermatitis in patients using lower limb prosthetics.MethodsThe current randomized, double-blind, placebo-controlled clinical trial was conducted on ninety-five participants with lower extremity amputation using limb prosthetics, aged 12–70 years who complained of contact dermatitis. They were randomly assigned to receive either two weeks of topical henna preparation every night as the intervention group, or topical placebo as the control group. Participants were instructed to spread henna preparation on the surfaces of the amputated limb that were in contact with the prosthesis. Severity of contact dermatitis symptoms was set as the primary outcome measure. Edema, papules and erythema were evaluated by a physician using standard color atlas. Secondary outcomes included symptoms such as burning, itching, pain, thickness and skin sweating evaluated by a self-administered questionnaire.ResultsA significant improvement was observed in the symptoms of contact dermatitis including skin edema, itching, sweating, skin thinning and pain (p-value<0.05) in the henna group compared to the placebo group. Skin burning decreased more in the henna group compared to the placebo group, but this was not statistically significant (p-value = 0.052). Moreover, skin redness significantly increased in the henna group (p-value = 0.001).ConclusionTopical formulation of henna might be a complementary choice for improving contact dermatitis in patients using lower limb prosthetics.     

The Relationship Between Mindfulness,Triage Accuracy,and Patient Satisfaction in the Emergency Department: A Moderation-Mediation Model

IntroductionIndividual and collective mindfulness attracts growing research attention, yet reports of their impact on health care professionals’ work behaviors are scarce, especially in the emergency department. The aim of the current study was to explore whether the association between trait mindfulness and triage accuracy is moderated by the emergency workload environment, and whether this association promotes patient satisfaction subject to levels of collective mindfulness.MethodsA prospective consecutive nested design was conducted. Data were collected from ED teams (nurses and physicians, N = 96) on individual characteristics and trait mindfulness. Data were also collected on triage accuracy, triage team characteristics, collective mindfulness, workload, and patient satisfaction (N = 960) at a specific patient–ED team encounter.ResultsFindings indicated that ED workload environment (b = 0.24, P < 0.01), trait mindfulness (b = 1.80, P < 0.01), and their interaction (b = −0.04, P < 0.05) were associated with triage accuracy. Triage accuracy (b = 1.81, P < 0.001), collective mindfulness (b = 1.29, P < 0.001), and their interaction (b = −0.32, P < 0.001) were associated with patient satisfaction. The moderated-mediation model was significant under high, but not under extreme, levels of ED workload environment and all levels of collective mindfulness.DiscussionTrait and collective mindfulness are relevant to ED triage and patient satisfaction, but their effects are bounded by workload. The beneficial gain of nurses’ trait mindfulness on triage accuracy and collective mindfulness on patient satisfaction is demonstrated only under high-workload environments but limited under extreme-workload environments.     

A Comparison of Three Methods,Utilizing Different Principles,for the Determination of Uric Acid in Biological Fluids

Abstract

Objective: The aim of the study was to compare endocrine parameters such as leptin, visfatin, insulin resistance, exercise capacity and body composition change, the pulmonary functions test (PFT) and arterial blood gases (ABG) parameters of chronic obstructive pulmonary disease (COPD) patients and in healthy controls. Materials and method: Fifty-five patients with COPD and without malnutrition and 25 healthy controls were included in our study. The serum leptin, visfatin, tumor necrosis factor alpha (TNF-α) and insulin resistance, body fat-free mass (FFM) and fat mass (FM) were measured in the groups. Additionally, body mass index (BMI) was calculated and the 6-minute walk test (6MWT), PFT and ABG analyses were performed in all of the cases. Results: No difference in BMI between the COPD group and controls was determined. Serum leptin and visfatin levels, FFM and 6MWT distance were significantly lower in the patients with COPD (p < 0.001, p = 0.001, p = 0.032, p < 0.001, respectively). A correlation was found between serum leptin levels and BMI (r = 0.333, p = 0.027), and with FM (r = 0.365, p = 0.029). Serum visfatin level was correlated with the percentage of forced expiratory volume in the first second in the patients with COPD (r = 0.371, p = 0.013). HOMA-IR (Homeostasis model assessment of insulin resistance) and serum TNF-α levels in the patients with COPD were found to be significantly higher than controls (p = 0.001, p < 0.001). Conclusion: These results may be earlier signs for further diseases that can emerge in the advanced stages in patients with COPD. Evaluating the patients not only with the pulmonary function and also systemically, contributes to minimizing the mortality and morbidity.     

Greater Adherence and Persistence with Injectable Dulaglutide Compared with Injectable Semaglutide at 1-Year Follow-up: Data from US Clinical Practice

PurposeGreater medication adherence and persistence have been associated with improved glycemic control in patients with type 2 diabetes mellitus. This study compared adherence, persistence, and treatment patterns among patients naïve to glucagon-like peptide 1 receptor agonists initiating once-weekly injectable treatment with dulaglutide versus semaglutide over 6-month (6M) and 12-month (12M) follow-up periods.MethodsThis retrospective, observational cohort study used administrative claims data from three IBM MarketScan research databases. Data from adult patients with type 2 diabetes newly initiating treatment with dulaglutide or semaglutide between January 2018 and January 2020 (index date was defined as the earliest fill date), without evidence of glucagon-like peptide 1 receptor agonist use in the 6M baseline period, and with continuous enrollment in the 6M baseline and 6M or 12M follow-up period were included. Dulaglutide initiators were propensity score–matched, in a 1:1 ratio, to semaglutide initiators in each 6M and 12M follow-up cohort (26,284 and 13,837 pairs, respectively).FindingsIn the matched cohorts, baseline characteristics were balanced; the mean age was 53 years, and 50% of patients were women. Compared to semaglutide initiators, dulaglutide initiators were more adherent (6M, 63.4% vs 47.8%; 12M, 54.4% vs 43.3%; both, P < 0.0001), more persistent on therapy (6M, 72% vs 62%, 12M, 55.5% vs 45.3%, both, P < 0.001), and had more mean days of persistence (6M, 145 vs 132, 12M, 254.3 vs 220.7; both, P < 0.001).ImplicationsAt both 6M and 12M follow-up, dulaglutide initiators had significantly greater adherence and greater persistence compared with matched semaglutide initiators.     

Effects of morphine on P2Y12 platelet inhibitors in patients with acute myocardial infarction: A meta-analysis

ObjectiveTo explore the effects of morphine on P2Y₁₂ platelet inhibitors in patients with acute myocardial infarction (AMI).MethodsPubMed, Embase, Cochrane Library, and Web of Science were used to retrieve literature through 11th May 2019. Standardized weighted mean difference (SMD) and relative risk (RR) with 95% confidence intervals (CI), P-value, and I² value were used to assess the strength of the association in this meta-analysis. Outcomes included platelet reactivity, high residual platelet reactivity (HRPR), ticagrelor maximum concentration (Cmax), ticagrelor area under curve (AUC), death rate, reinfarction rate, stroke, stent thrombosis, thrombolysis in myocardial infarction (TIMI) hemorrhage, dyspnea, emesis, contrast-induced nephropathy, and pulmonary edema.ResultsA total of 13 articles were included in this study, containing 5688 patients (morphine group: n = 2014, control group: n = 3674). Results illustrated that the morphine group had a higher platelet reactivity (SMD: 0.834, 95%CI: 0.483–1.186, P < 0.001) and HRPR rate (RR: 1.994, 95%CI: 1.536–2.588, P < 0.001) than the control group, while the Cmax of ticagrelor (WMD: -481.838, 95%CI: −841.242–122.434, P = 0.009) was lower than that of the control group. The death rate of the morphine group was lower than that in the control group (RR: 0.561, 95%CI: 0.337–0.933, P = 0.026). The morphine group had a higher emesis rate than the control group (RR: 4.486, 95%CI: 2.263–8.891, P < 0.001).ConclusionMorphine effectively suppresses the inhibition effect of P2Y₁₂ platelet inhibitors in patients with AMI.     

Efficacy and Safety of a Fixed-Dose Combination of Candesartan and Rosuvastatin on Blood Pressure and Cholesterol in Patients With Hypertension and Hypercholesterolemia: A Multicenter,Randomized, Double-Blind,Parallel Phase III Clinical Study

PurposeThe aim of this study was to evaluate the blood pressure–lowering and cholesterol-lowering effects of a fixed-dose combination therapy using candesartan (CND)/rosuvastatin (RSV) compared with CND or RSV monotherapy in patients with hypertension and hypercholesterolemia.MethodsThis study was a 12-week, randomized, double-blind, placebo-controlled, multicenter study. A total of 394 patients were screened. After a 4-week run-in period, 219 of these patients with hypertension and primary hypercholesterolemia were randomized. Patients received 1 of 3 regimens for 8 weeks: (1) CND 32 mg/RSV 20 mg, (2) RSV 20 mg, or (3) CND 32 mg. The primary outcome variables were changes in the systolic blood pressure (SBP) and diastolic blood pressure (DBP) and the percentage changes in LDL-C from baseline to the drug treatment at 8 weeks. The secondary outcome variables were percentage changes of total cholesterol, triglycerides, HDL-C, non–HDL-C, apolipoprotein B, apolipoprotein A-I, high-sensitivity C-reactive protein, and glucose metabolic indices, including percentage changes of the homeostasis model assessment of insulin resistance (HOMA-IR), adiponectin, and hemoglobin A_1c. Tolerability of combination therapy was compared with other monotherapy groups.FindingsThe percentage changes of LDL-C were ?48.6% (from 157.2 to 80.1 mg/dL) in the RSV group and ?49.8% (from 160.2 to 78.9 mg/dL) in the CND/RSV group from baseline to the end of 8 weeks of treatment. Mean SBP and DBP were significantly decreased in the CND/RSV and CND groups after 8 weeks (P < 0.001 for all); however, no significant differences were found between the 2 groups. Total cholesterol levels, triglycerides, non–HDL-C, and apolipoprotein B were significantly reduced in the CND/RSV and RSV groups, with no significant differences between the groups compared with the CND group (P < 0.001 for all). The percentage changes of HOMA-IR, adiponectin, and hemoglobin A_1c had no significant differences between the combination groups and monotherapy groups. However, in a 2-sample t test, HOMA-IR was significantly decreased in the CND/RSV group compared with the RSV group in nondiabetic patients (mean [SD] percentage change of HOMA-IR, ?8.7% [37.6%] vs 17.1% [53.1%]; P = 0.048). There were no significant differences in metabolic indices between the diabetic groups. Adverse events in the CND/RSV group were similar to those in the monotherapy group.ImplicationsOnce-daily fixed-dose combination therapy with CND/RSV is an effective, tolerable, convenient treatment option for patients with essential hypertension and hypercholesteremia.

Diffusion based MR measurements correlates with age-related changes in human intervertebral disks

BackgroundUnderstanding the association between MR parameters and age related deterioration in human intervertebral disks forms an important step in the development of clinical diagnostic protocols for disk disease.MethodsTen unfixed thoracic and lumbar cadaver disk joints, age 37–81 years were imaged at 9.4 T using T2 relaxation (CPMG) and ADC (DWI spin echo) MR protocols. For each MR parameter, spatial maps were computed from the axial images, with the AF and NP segmented based on the T2 maps. Linear regression tested for the correlation between mean and variance (COV) of T2 and ADC with age in the disk, nucleus and annulus, and the effect of thoracic vs. lumbar spine on these correlations.FindingsIn the disk, age negatively correlated with mean ADC (P < 0.001) and positively with COV of ADC (P < 0.001) and T2 (P < 0.05). Age was negatively correlated with mean T2 (P < 0.01), mean ADC (P < 0.001) and positively with COV of ADC (P < 0.001) and T2 (P < 0.05) in the NP and positively correlated with mean T2 (P < 0.05), COV of ADC (P < 0.01) and T2 (P < 0.05) and negatively with mean ADC (P < 0.05) in the AF. Compared to thoracic disks, lumbar disks showed higher mean ADC (P < 0.05), lower mean T2 (P < 0.001) and higher COV of ADC (P < 0.01) and T2 (P < 0.05).InterpretationCompared to T2, MR diffusion was a more sensitive measure of age mediated changes in disk tissues. Strong differences in the association of MR parameters with age between the lumbar and thoracic suggest that mechanical environment effects tissue specific MR parameters' association with age.     

Association between metformin and survival outcomes in in-hospital cardiac arrest patients with diabetes

IntroductionMetformin has shown cardioprotective and neuroprotective effects in cardiac arrest and ischemia-reperfusion injury animal models. Therefore, this study aimed to determine the association between diabetes medication and survival outcomes in in-hospital cardiac arrest (IHCA) patients with type 2 DM (T2DM).MethodsThis retrospective observational study included adult IHCA patients with T2DM between April 2017 and March 2022. The variable of interest was administration of diabetes medications within 24 h before cardiac arrest. Multivariable logistic regression analysis was performed.ResultsIn the 377 included patients, administration of metformin within 24 h before IHCA was associated with a higher rate of survival to discharge and good neurologic outcome (41.5% vs 11.7%, P < 0.001 and 18.9% vs 6.2%, P = 0.004, respectively). Administration of metformin within 24 h before IHCA was independently associated with survival to discharge and good neurologic outcome (aOR: 5.37, 95% CI: 2.13–13.53, P < 0.001 and aOR: 3.57, 95% CI: 1.14–11.17, P = 0.029). The rate of survival to discharge was the highest in patients who were administered 500–1000 mg/day metformin (P < 0.001).ConclusionsIn IHCA patients with T2DM, administration of metformin within 24 h before IHCA was independently associated with survival to discharge.     

Blood pressure-lowering effects of extended-release niacin alone and extended-release niacin/laropiprant combination: A post hoc analysis of a 24-week,placebo-controlled trial in dyslipidemic patients

Background: Dyslipidemia and high blood pressure are both major cardiovascular disease risk factors. Niacin is an effective lipid-altering agent that has been reported to reduce the risk of cardiovascular disease. However, the more widespread use of niacin is limited, mainly due to the occurrence of flushing. Laropiprant (LRPT) is a selective antagonist of prostaglandin D₂ receptor subtype 1 that reduces extended-release niacin (ERN)-induced flushing without affecting its beneficial lipid effects. While the lipid effects of ERN are well known, the blood pressure effects are unclear.Objective: The aim of this analysis was to examine the blood pressure effects of ERN and ERN/LRPT.Methods: This was a post hoc analysis of a 24-week, worldwide, multicenter, double-blind, randomized, placebo-controlled, parallel, Phase III, previously published study of dyslipidemic patients, which examined the effect of ERN and ERN/LRPT on systolic blood pressure (SBP) and diastolic blood pressure (DBP).Results: A total of 1613 men and women, aged 21 to 85 years, with primary hypercholesterolemia or mixed dyslipidemia (66% on statins), were included in the original analysis. ERN alone, or in combination with LRPT, was associated with significant reductions in SBP and DBP at 24 weeks from baseline. The placebo-adjusted mean changes from baseline at week 24 in SBP were ?2.2 and ?3.1 mm Hg for the ERN and ERN/LRPT groups, respectively (P < 0.05 and P < 0.001). Similar changes in DBP were observed; ?2.7 and ?2.5 mm Hg in the ERN and ERN/ LRPT groups, respectively (both, P < 0.001).Conclusion: This post hoc analysis of a 24-week trial found that ERN alone, or in combination with LRPT, was associated with significant placebo-adjusted reductions from baseline in blood pressure in these hyperlipidemic hypertensive or normotensive subjects.     

Increased serum levels of microvesicles in nonvalvular atrial fibrillation determinated by ELISA using a specific monoclonal antibody AD-1

BackgroundMicrovesicles are involved in different pathological processes such as inflammation, coagulation and tumor progression. We intended to establish an immunoaffinity capture method for detecting microvesicles and bioactive effectors carried on them using a specific homemade monoclonal antibody AD-1. By this method we investigated the association of inflammation with platelet activation in patients with nonvalvular atrial fibrillation (NVAF).MethodsA case–control study of 90 Chinese subjects selected in 3 groups: control, paroxysmal AF, and persistent AF. After capturing the microvesicles of serum using a specific monoclonal antibody AD-1, the amounts of LAP, IL-1β and P-selectin loaded on these microvesicles were quantified by either enzyme activity assay (LAP) or ELISA respectively.ResultsCompared with normal controls, the patients with persistent AF showed significantly increased serum levels of microvesicles (P < 0.001), microvesicle-bound IL-1 β (P = 0.019) and microvesicle-bound P-selectin (P = 0.001). The latter two were significantly correlated with each other (r² = 0.371, r = 0.616, P < 0.001). The microvesicle-bound IL-1β (β = 0.570, P < 0.001) and body weight (β = 0.427, P = 0.002) were as independent predictors of platelet activation.ConclusionsThe method was easy and reproducible. Inflammation may be involved in the activation of platelets in NVAF.     

Effects of Postoperative Percutaneous Coronary Intervention,Pharmacologic Treatment,and Predisposing Factors on Clinical Outcomes in Patients With and Without Type 2 Diabetes Along With Critical Limb Ischemia

PurposeCritical limb ischemia (CLI) has been identified as being connected to rates of cardiovascular mortality and lower extremity amputation (LEA). This prospective study investigated the effects of percutaneous coronary intervention (PCI), pharmacologic treatment, and predisposing factors on clinical outcomes in patients with and without type 2 diabetes mellitus (DM) along with CLI after endovascular intervention.Methods249 consecutive patients with CLI (Fontaine stages III–IV) received pharmacologic treatment after successful endovascular intervention. Their primary patency rates of infrapopliteal lesions and cardiovascular and amputation events during a 36-month follow-up period were assessed.FindingsPatients with DM were more likely to be younger (P = 0.026); 50% (n = 63), 42.9% (n = 54), 52.4% (n = 66), and 77% (n = 97) of DM patients had arterial calcification, end-stage renal disease, diabetic neuropathy, and Fontaine stage IV (P < 0.001, P < 0.001, P < 0.001, and P = 0.019, respectively). The primary patency rates were 61%, 48.8%, and 42.3% at 12, 24, and 36 months, in the patients without DM (P = 0.034, P = 0.013, and P = 0.005). Patients with DM had higher risks of 36-month coronary artery disease, cerebrovascular accident, mortality, and LEA (P = 0.005, P = 0.042, P = 0.042, and P < 0.001). Patients with CLI receiving long-term cilostazol treatment had a better primary patency and amputation-free survival, and a lower risk of mortality at 36 months (P < 0.001, P < 0.001, and P = 0.001). Statin use was associated with 36-month amputation-free survival but not with primary patency (P = 0.032 and P = 0.088). Subgroup multivariate Cox analyses showed that primary patency was independently associated with long-term cilostazol treatment, PCI in the first postoperative year, and direct revascularization in the DM group, whereas in the control group, long-term cilostazol treatment was the main independent factor. The risk of amputation was independently associated with a high high-sensitivity chronic reactive protein level, diabetic neuropathy, sole use of an oral hypoglycemic agent, and lack of supervised exercise.ImplicationsLong-term cilostazol treatment, aggressive management of dyslipidemia, and meticulous assessment and prevention of postoperative unstable coronary artery disease should be considered in CLI patients with and without DM to maximize clinical outcomes. PCI in the first postoperative year may be a predisposing factor for patency failure in patients with CLI, especially those with DM. A large-scale prospective randomized trial should be conducted to confirm these findings (TVGH IRB No. 2013-08-020B).
