Procalcitonin, brain natriuretic peptide and albumin as markers to predict prognosis in hospitalized older Japanese patients with a risk of infection.

AIM: Whether serum concentration of procalcitonin (PCT), brain natriuretic peptide (BNP) and albumin (Alb) have an association with the outcome of hospitalized older patients is unclear. We investigated clinical outcomes and any predictive factors in hospitalized Japanese older patients with a risk of infection. METHODS: In the retrospective study, 820 Japanese patients were followed up for 30 days or until death. During the observation period, 656 patients survived and 164 patients died. The predictive factors of death were analyzed according to demographic and clinical variables. RESULTS: The survival rate was decreased as the serum PCT increased from <0.5 to ≥10 ng/mL, as was also the case with BNP from <300 to ≥300 pg./mL, whereas low Alb (<2.5 g/dL) showed a lower survival rate than high Alb (≥2.5 g/dL; P < 0.01). Using the Cox regression model, the multivariable-adjusted hazard ratios (95% confidence interval) were as follows: PCT 0.5-2 versus <0.5 ng/mL: 1.61(1.04-2.49), PCT 2-10 versus <0.5 ng/mL: 1.91(1.15-3.16), PCT ≥10 versus <0.5 ng/mL: 2.90(1.84-4.59), high BNP 1.26 (0.89-1.76) and low Alb 0.68 (0.52-0.87). The mortality rate increased as the number of scores (PCT + BNP + Alb) increased. CONCLUSIONS: Concentration-dependent high PCT, high BNP and low Alb were positive risk factors associated with poor prognosis in hospitalized older patients with a risk of infection.

The Impact of Tofogliflozin on Physiological and Hormonal Function, Serum Electrolytes, and Cardiac Diastolic Function in Elderly Japanese Patients with Type 2 Diabetes Mellitus.

The sodium glucose transporter 2 (SGLT2) inhibitor tofogliflozin is a glucose-lowering drug that causes the excretion of surplus glucose by inhibiting SGLT2. Because of tofogliflozin's osmotic diuresis mechanism, patients' serum electrolytes, body fluid levels, and cardiac function must be monitored. We retrospectively analyzed the cases of 64 elderly Japanese patients with type 2 diabetes mellitus (T2DM) who received tofogliflozin for 3 months. Their HbA1c, serum electrolytes (sodium, potassium, chloride), hematocrit, brain natriuretic peptide (cardiac volume load marker) and renin and aldosterone (RAA; an index of regulatory hormones involved in body fluid retention) were continuously monitored during the investigation period. Renal function and cardiac function (by echocardiography) were assessed throughout the period. HbA1c significantly decreased (ß1=-0.341, p<0.0001, linear regression analysis [LRA]). Most of the hormonal, electrolyte, and physiological parameters were maintained throughout the study period. In these circumstances, E/e' tended to decrease (ß1=-0.382, p=0.13, LRA). Compared to the baseline, E/e' was significantly decreased at 1 and 3 months (p<0.01, p<0.05). In the higher E/e' group (E/e'≥10, n=34), E/e' decreased significantly (ß1=-0.63, p<0.05, LRA). ΔE/e' was correlated with body-weight change during treatment (r=0.64, p<0.01). The 3-month tofogliflozin treatment improved glycemic control and diastolic function represented by E/e' in T2DM patients, without affecting serum electrolytes, renal function, or RAA. No negative impacts on the patients were observed. Three-month tofogliflozin treatment lowered glucose and improved cardiac diastolic function.

A new predictive tool consolidating CURB-65 with procalcitonin and albumin to assess short-term mortality in hospitalized elderly patients with infectious disease: A retrospective study of a patient cohort.

BACKGROUND: Hospitalized elderly patients are often at risk of life-threatening infectious diseases such as pneumonia and urinary tract infection, thus diagnostic tools for bacterial infections are demanded. We developed a new predictive tool consolidating modified CURB-65, procalcitonin (PCT) and albumin (Alb). METHOD: This is a retrospective study. Modified CURB-65 (mCURB-65) score, PCT, Alb, and various cardiovascular/respiratory/renal functions were measured. Survival analyses were conducted to assess 30-days mortality of elderly patients using mCURB-65 score, PCT and Alb. The consolidated scores were compared with the number of patients died. RESULTS: There were 445 elderly patients included. Kaplan-Meier survival curves showed significant differences between the high and low groups of mCURB-65, PCT and Alb (log-rank test, P < .001). Cox proportional regression showed that the hazard ratios (95% confidence intervals) for high mCURB-65, high Alb, and high PCT were all significant, 1.95 (1.24-3.05), 0.50 (0.32-0.77), and 2.09 (1.32-3.31), respectively. The consolidated scores showed tendency of increase with proportion of the number of patients died. CONCLUSIONS: The consolidated score consisted of mCURB-65, PCT and Alb can be a useful tool to predict short-term mortality of the hospitalized elderly patients with infectious disease.

Orthogeriatric co-management at a regional core hospital as a new multidisciplinary approach in Japanese hip fracture operation.

BACKGROUND: This study aimed to evaluate the effects of orthogeriatric co-management of hip fractures at a regional core hospital. METHODS: This study included patients with proximal hip fracture. Patients were divided into two groups, conventional multidisciplinary group I including patients attending the hospital between April 2015 and March 2016 and orthogeriatric group II including patients attending the hospital between April 2016 and March 2017, which were compared etrospectively. In the control group, the conventional multidisciplinary team treated patients as whole-body controls. In the intervention group, the newly recruited geriatricians performed physical examinations, laboratory tests, radioactive imaging, and physiological tests. Furthermore, they consulted ward pharmacists, rigorously conducted positive polypharmacy interventions , and evaluated the type and number of mediated drugs on admission. RESULTS: The number of medicated drugs significantly decreased from 6.03 ± 4.3 on admission to 5.50 ± 3.59 on discharge in group II, whereas group I did not show a significant decrease. Despite the more number of hospitalized patients in group II (166 patients) than in group I (126 patients), the recovery rate from postoperative urinary retention increased significantly from 57.8% (19/30) in group I to 84.3% (32/59) in group II (p = 0.049), while the incidence of aspiration pneumonia decreased from 7.1% (9/126) in group I to 2.49% (4/166) in group II (p = 0.08). The patients received six or more prescribed drugs on admission, and the number remained constant. However, the number of medicated drugs on discharge showed a marginally significant decrease from 6.03 ± 4.3 in group I to 5.50 ± 3.59 in group II (p < 0.05). CONCLUSIONS: Compared to the conventional multidisciplinary group, the orthogeriatric team contributed to reducing the number of multi-effect drugs and perioperative complications without negatively affecting mortality despite the increased number of patients. The in-hospital mortality rate did not change between the groups. The orthogeriatric program succeeded in preventing and treating perioperative complications.

Postoperative Urinary Retention in Japanese Elderly Males with a Femoral Neck or Trochanteric Fracture.

We assessed risk factors for postoperative urinary retention (UR) in elderly males with femoral bone fractures: 169 Japanese males (mean age 81.95 ± 1.19 years) who had undergone hip surgery at a municipal hospital (Toyama, Japan). A multiple logistic regression analysis was used to test possible risk factors for UR: age, body mass index, serum albumin, cognitive impairment, activities of daily living (ADL), and history of diabetes mellitus (DM). UR occurred in 24 (14.2%) of the 169 patients. A multivariate logistic regression analysis with age adjustment showed that ADL (odds ratio [OR] 3.88; 95% confidence interval [CI]: 1.2-12.5, p=0.023) was significantly associated with the development of UR, and a history of DM showed marginal significance for UR occurrence (OR 0.36, 95%CI: 0.11-10, p=0.064). These results suggests that ADL is a risk factor for UR development in elderly males who have undergone surgery for femoral neck or trochanter fractures.

Women Physicians in Academic Medicine of Japan.

Japan is a well-qualified country in promoting scientific advancement, but female scientists are too few in academic medicine positions. The government of Japan announced that the share of women in leadership positions accounted to at least 30% by 2020 in all fields in society. The number of female students also increased, but it was not much higher than other Organisation for Economic Co-operation and Development (OECD) countries. Women students always have higher passing frequencies in national examination for medical practitioners in Japan. The potential gap between physician gender and academic advancement is mentioned in any medical fields. Women physicians in academic medicine position are still few. For women physicians, medical and familial situations are inversely affected by the coronavirus disease 2019. We propose the recommendations to support women physicians' right in academic medicine, accordingly to patients' benefit. Women may be stepping up and leading efforts without titles or positions in ways that are significant and meaningful for their group or organization.

Effects of tofogliflozin on adrenocorticotropic hormone, renin and aldosterone, and cortisol levels in elderly patients with diabetes mellitus: A retrospective study of a patient cohort.

ABSTRACT: Adrenocorticotropic hormone (ACTH) and cortisol reportedly play a role in glycemic control in patients with type 2 diabetes mellitus (T2DM); however, the underlying mechanism remains controversial. We retrospectively investigated the effect of tofogliflozin on serum ACTH and cortisol levels in elderly patients with T2DM.Patients received 20 mg tofogliflozin daily for 3 months. Serum ACTH and cortisol levels were measured at baseline, as well as after 1 month and 3 months of tofogliflozin therapy.Serum ACTH levels were significantly reduced 3 months after tofogliflozin treatment (P < .01). Additionally, serum cortisol levels were reduced 3 months after tofogliflozin treatment, demonstrating borderline significance (P = .05). The higher body mass index (BMI; ≥25 kg/m2) group showed higher ACTH and cortisol levels than the lower BMI (<25 kg/m2) group, with borderline significance (P = .05). Renin levels were significantly increased 1 month after treatment (P < .05), maintaining serum aldosterone levels in parallel with the extracellular fluid.Our findings suggested that tofogliflozin decreased both serum ACTH and cortisol levels, with higher levels observed in the high BMI group. Tofogliflozin increased serum renin levels while maintaining serum aldosterone and extracellular fluid levels. Collectively, tofogliflozin could affect the hypothalamic-pituitary-adrenal pathway in patients with T2DM, especially in the low BMI group.

Gender Differences in Cardiac Function Following Three-Month Administration of Tofogliflozin in Patients With Diabetes Mellitus.

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) are at increased risk for impairment in heart failure and diastolic relaxation while preserving ejection fraction (EF). Recently, several sodium glucose cotransporter-2 (SGLT2) inhibitors have demonstrated to decrease cardiovascular disease (CVD) events in elderly diabetic patients, although gender difference in the effect of SGLT2 inhibitors is unknown. The objective of the present study was to evaluate gender difference in the effect of tofogliflozin, one of the SGLT2 inhibitors, on CVD function in patients with diabetes mellitus. METHODS: This was a retrospective study. Patients received 20 mg of tofogliflozin daily for 3 months. EF, ratio of early filling to atrial filling (E/A), a change in mitral inflow E and mitral e' annular velocities (E/e'), left atrial dimension (LAD) and maximal diameter of inferior vena cava (IVCmax), including various physiological parameters were measured between baseline, 1 month and 3 months after administration of tofogliflozin. Interaction between gender and time after administration was evaluated using mixed effect model. RESULTS: The results showed significant decrease in E/e' (P < 0.01) and significant interaction between time and gender in E/A (P < 0.01), following administration of tofogliflozin for 3 months. EF was constantly higher significantly in women (P < 0.01). CONCLUSION: It is concluded that 3-month administration of tofogliflozin decreased E/e' with gender difference in EF and E/A.

Neuroinflammation, Oxidative Stress, and Neurogenesis in a Mouse Model of Chronic Fatigue Syndrome, and the Treatment with Kampo Medicine.

The diagnosis of chronic fatigue syndrome (CFS) is mainly symptom-based, and the etiology is still unclear. Here, we evaluated the pathological changes in the brain of a mouse model of CFS and studied the effects of Kampo medicine. A mouse model of CFS was established through six repeated injections of Brucella abortus (BA) every two weeks for a period of 12 weeks. Neuroinflammation was measured by estimating interleukin (IL)-1ß, IL-6, and interferon-gamma (IFN-γ), and oxidative stress by nitrotyrosine (3-NT) and 4-hydroxynonenal (4-HNE) 6 weeks after the last injection. Hippocampal neurogenesis was evaluated through Ki-67, doublecortin (DCX), and 5-bromodeoxyuridine (BrdU) assays. The effects of Kampo medicines (Hochuekkito (TJ-41) and Hachimijiogan (TJ-7)) on neuroinflammation during CFS were studied. The wheel-running activity of mice was decreased by about 50% compared to baseline at 6 weeks after the last BA injection. The levels of IL-1ß, IL-6, 3-NT, and 4-HNE were increased in both the cortex and the hippocampus of CFS mice at 6 weeks after the last BA injection. Hippocampal neurogenesis was unchanged in CFS mice. Treatment with TJ-41 and TJ-7 reduced the expressions of IL-1ß, IL-6, and IFN-γ in the hippocampus but not in the cortex. The results of the present study indicate that neuroinflammation and oxidative stress play important roles in the pathogenesis of CFS. The data further suggest that treatment with TJ-41 and TJ-7 could help reduce the inflammation associated with CFS in the hippocampus, but failed to improve the symptoms in CFS mice.

Genetic factors associated with elevation of uric acid after treatment with thiazide-like diuretic in patients with essential hypertension.

We investigated changes in blood pressure (BP) and metabolic adverse effects, especially elevation of uric acid (UA), after treatment with a thiazide-like diuretic (TD) in patients with essential hypertension. Furthermore, the role of genetic factors in the elevation of UA by TD was assessed by a 500 K SNP DNA microarray. The subjects included 126 hypertensive patients (57 women and 69 men, mean age 59 ± 12 years) who registered for the GEANE (Gene Evaluation for ANtihypertensive Effects) study. After one month of the nontreatment period, TD, indapamide, angiotensin II receptor antagonist valsartan, and Ca channel blocker amlodipine were administered to all patients for 3 months each in a randomized crossover manner. BP, renal function, serum UA level, and electrolytes were measured at baseline and at the end of each treatment period. Single nucleotide polymorphisms (SNPs) associated with UA elevation after treatment with indapamide were investigated by a genome-wide association study (GWAS). Indapamide significantly decreased both office and home BP levels. Treatment with indapamide also significantly reduced the estimated glomerular filtration rate and serum potassium and increased serum UA. Patients whose UA level increased more than 1 mg/dl showed significantly higher baseline office SBP and plasma glucose and showed greater decline in renal function compared with those who showed less UA increase (<1 mg/dl). Some SNPs strongly associated with an increase in UA after treatment with indapamide were identified. This study is the first report on SNPs associated with UA elevation after TD treatment. This information may be useful for the prevention of adverse effects after treatment with TD.

Comorbidity of chronic kidney disease, diabetes and lower glycated hemoglobin predicts support/care-need certification in community-dwelling older adults.

AIM: Chronic kidney disease (CKD), diabetes and lower glycated hemoglobin (HbA1c ) range in diabetes patients are associated with higher mortality. We investigated whether these conditions were associated with the risk of loss of independence in community-dwelling older adults. METHODS: We analyzed 1078 older adults with no history of support/care-need certification in Long-Term Care Insurance aged 65-94 years. Associations of baseline CKD, diabetes, and lower HbA1c range of <6.0% in the diabetes patients, at baseline health checkup with risk of later certification and/or death for 5 years were estimated using the Cox proportional hazards regression model. RESULTS: The prevalence of both CKD and diabetes in the total population increased with age, due to a net increase in the coexistence of CKD and diabetes. The prevalence of the lower HbA1c range also increased with age in participants with the coexistence. During 5 years, 135 certifications and 53 deaths occurred. After adjustment, patients with comorbidity of the triad of CKD, diabetes and the lower HbA1c range had significantly higher hazard ratios (HR) for certification (HR 3.52, 95% confidence interval [CI] 1.91-6.48, P < 0.001) and for death (HR 3.79, 95% CI 1.46-9.85, P = 0.006) compared with those without CKD and diabetes. The harmful impact of the lower HbA1c range on later certification compared with higher HbA1c range of ≥6.0% was maintained in diabetes patients with use of antidiabetic agents and CKD (HR 2.40, 95% CI 1.06-6.45, P = 0.036). CONCLUSIONS: Excessive HbA1c reduction might cause discontinuance of disability-free survival in community-dwelling older diabetes patients with CKD. Geriatr Gerontol Int 2018; 18: 521-529.

Case study of early detection and intervention of infectious disease outbreaks in an institution using Nursery School Absenteeism Surveillance Systems (NSASSy) of the Public Health Center.

Objectives Detecting outbreaks early and then activating countermeasures based on such information is extremely important for infection control at childcare facilities. The Sumida ward began operating the Nursery School Absenteeism Surveillance System (NSASSy) in August 2013, and has since conducted real-time monitoring at nursery schools. The Public Health Center can detect outbreaks early and support appropriate intervention. This paper describes the experiences of Sumida Public Health Center related to early detection and intervention since the initiation of the system.Methods In this study, we investigated infectious disease outbreaks detected at 62 nursery schools in the Sumida ward, which were equipped with NSASSy from early November 2013 through late March 2015. We classified the information sources of the detected outbreak and responses of the public health center. The sources were (1) direct contact from some nursery schools, (2) messages from public officers with jurisdiction over nursery schools, (3) automatic detection by NSASSy, and (4) manual detection by public health center officers using NSASSy. The responses made by the health center were described and classified into 11 categories including verification of outbreak and advice for caregivers.Results The number of outbreaks detected by the aforementioned four information sources was zero, 25, 15, and 7 events, respectively, during the first 5 months after beginning NSASSy. These numbers became 5, 7, 53, and 25 events, respectively, during the subsequent 12 months. The number of outbreaks detected increased by 47% during the first 5 months, and by 87% in the following 12 months. The responses were primarily confirming the situation and offering advice to caregivers.Conclusion The Sumida Public Health Center ward could achieve early detection with automatic or manual detection of NSASSy. This system recently has become an important detection resource, and has contributed greatly to early detection. Because the Public Health Center can use it to achieve real-time monitoring, they can recognize emergent situations and intervene earlier, and thereby give feedback to the nursery schools. The system can contribute to providing effective countermeasures in these settings.

Genome-wide response to antihypertensive medication using home blood pressure measurements: a pilot study nested within the HOMED-BP study.

BACKGROUND: Patients with mild-to-moderate essential hypertension in the HOMED-BP trial were randomly allocated to first-line treatment with a calcium channel blocker (CCB), angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB). METHODS: We recruited 265 (93 for CCB, 71 for ACEI and 101 for ARB) patients who completed the genomic study. Home blood pressure was measured for 5 days off-treatment before randomization and for 5 days after 2-4 weeks of randomized drug treatment. Genotyping was performed by 500K DNA microarray chips. The blood pressure responses to the three drugs were analyzed separately as a quantitative trait. For replication of SNPs with p < 10(-4), we used the multicenter GEANE study, in which patients were randomized to valsartan or amlodipine. RESULTS: SNPs in PICALM, TANC2, NUMA1 and APCDD1 were found to be associated with CCB responses and those in ABCC9 and YIPF1 were found to be associated with ARB response with replication. CONCLUSION: Our approach, the first based on high-fidelity phenotyping by home blood pressure measurement, might be a step in moving towards the personalized treatment of hypertension.

Mao-to Prolongs the Survival of and Reduces TNF-alpha Expression in Mice with Viral Myocarditis.

Goal of this study was to evaluate effects of Mao-to on development of myocarditis induced by encephalomyocarditis (EMC) virus in mice. Mice were randomly divided into five groups. Group N included uninfected controls (n = 18), while group A, B and C underwent intraperitoneal injection of EMC virus. Group A was administered oral saline from day 0 to day 4. Group B was administered oral Mao-to (500 mg(-1) kg(-1) day(-1)) from day 0 to day 4. Group C was administered Mao-to from day 2 to day 6. Group D was administered Mao-to from day 5 to day 10. Treated mice were followed for survival rates during 2 weeks after infection. Body weight (BW) and organ weights including heart (HW), lungs, thymus and spleen were examined on days 4, 6 and 14. Survival rate of group C (36.4%) was significantly improved compared with group A, B or D (0% of each, P < 0.05). HW and HW/BW ratio in group C was significantly (P < 0.05) lower than those in group A, B or D. Viral titers of hearts were significantly different among groups A, B and C. Cardiac expression in tumor necrosis factor-alpha (TNF-alpha) was significantly reduced in group C in comparison with group A, B or D on day 6 by immunohistochemical study. Administration of Mao-to starting on day 2 improves mortality resulting from viral myocarditis in mice with reduced expression of cardiac TNF-alpha. These findings suggest that timing of Mao-to is crucial for preventing cardiac damage in mice with viral myocarditis.

Silent information regulator, Sirtuin 1, and age-related diseases.

Sirtuin 1 (SIRT1), a member of the silent information regulator 2 in mammals, has recently been found to be involved in age-related diseases, such as cancer, metabolic diseases, cardiovascular disease, neurodegenerative diseases, osteoporosis and chronic obstructive pulmonary disease (COPD), mainly through deacetylation of substrates such as p53, forkhead box class O, peroxisome proliferator activated receptor gamma co-activator 1alpha, and nuclear factor-kappaB. It is widely reported that SIRT1 can promote not only carcinogenesis but also metastasis and insulin resistance, andhave beneficial effects in metabolic diseases, mediate high-density lipoprotein synthesis and regulate endothelial nitric oxide to protect against cardiovascular disease, have a cardioprotective role in heart failure, protect against neurodegenerative pathological changes, promote osteoblast differentiation, and also play a pivotal role as an anti-inflammatory mediator in COPD. However, there are controversial results suggesting that SIRT1 has an effect in protecting against DNA damage and accumulation of mutations, and preventing tumorigenesis. In addition, a high level of SIRT1 can induce cardiomyopathy and even heart failure. This article reviews recent developments relating to these issues.

Immobilization stress inhibits intimal fibromuscular proliferation in the process of arterial remodeling in rats.

We investigated role of beta-endorphin (END), which is released by immobilization stress, on intimal fibromuscular proliferation in a rat model of arterial remodeling after intimal injury. The endothelium of the abdominal aorta of Wistar-Kyoto rats was denuded, and the rats were subjected to immobilization stress (6 h/d), which raised the serum concentration of END, and intraperitoneal administration of either END (20 ng/kg/d) or naltrexone (NAL: 4 mg/kg/d). The proliferative activity (PA) of medial smooth muscle cells (SMCs) and the intima/media area ratio (R) were determined at 3 and 14 d after denudation, respectively. PA and R were significantly reduced by immobilization (PA: 64.8%, R: 34.6%), and NAL treatment completely reversed the decreases in PA and R. On the other hand, END reduced both PA and R (PA: 21.7% and R: 24.9%), and NAL also reversed the decreases in PA and R. END (20 pg/mL) inhibited both the proliferation (79% at 96 h) and migration (26%) of SMCs cultured with 5% fetal bovine serum in vitro, and NAL (100 microg/mL) reversed the inhibition of both activities. Our results suggest that immobilization stress stimulates the release of endogenous END, which then prevents both proliferation and migration of medial SMCs after intimal injury.

Candesartan improves myocardial damage in obese mice with viral myocarditis and induces cardiac adiponectin.

PURPOSE: To clarify the mechanism of the effects of angiotensin II receptor type 1 antagonist, candesartan, upon cardiac adiponectin in the combination of myocarditis with obesity, we examined obese KKAy mice with acute viral myocarditis treated by candesartan and investigated cardiac adiponectin regulation. METHODS: Mice were divided into candesartan early treatment group (Can-early) receiving orally candesartan at daily dose of 10 mg/kg 7 days starting before viral inoculation and then 7 days; candesartan late treatment group (Can-late) or vehicle (Vehicle) receiving candesartan starting simultaneously with viral inoculation and then 7 days. Encephalomyocarditis virus was used to induce the acute viral myocarditis. Differences in myocardial damages, serum adiponectin and myocardial expression of adiponectin, tumor necrosis factor-alpha (TNF-alpha), CCAAT/enhancer binding proteinalpha (C/EBPalpha) and peroxisome proliferator-activated receptor gamma (PPAR-gamma) and nuclear factor-kappaB (NF-kappaB) mRNA among three groups were determined on days 0, 4 and 7 after viral inoculation. RESULTS: Mice in Can-early and Can-late groups showed reduced myocardial necrosis and cellular infiltration as compared with those in the Vehicle. On day 4 the circulating adiponectin levels were significantly higher in Can-early than those in Vehicle. Mice in Vehicle had significantly reduced in myocardial adiponectin mRNA after viral myocarditis. Cardiac adiponectin mRNA was significantly higher in Can-early and in Can-late than in Vehicle on days 4 and 7. Cardiac C/EBPalpha in Can-early and Can-early groups was significantly increased on day 4. Myocardial NF-kappaB and TNF-alpha mRNA in Can-early and Can-late groups were significantly reduced on day 7. CONCLUSION: Candesartan treatment improved myocardial injury in obese mice with acute viral myocarditis and induced expression of cardiac adiponectin with the induction of C/EBPalpha as well as the reduction of cardiac NF-kappaB and TNF-alpha.
