Effectiveness of mat pilates on fatigue in women with breast cancer submitted to adjuvant radiotherapy: randomized controlled clinical trial.

PURPOSE: This clinical trial aimed to evaluate the influence of Mat Pilates and time on the change in fatigue scores in women with breast cancer undergoing adjuvant radiotherapy (RT). Additionally, assess the adherence and adverse effects of Mat Pilates sessions and the association of the level of physical activity with severe fatigue symptoms. METHODS: One hundred fifty-six patients with non-metastatic breast cancer were randomized to usual care or supervised Mat Pilates exercise. Fatigue and physical activity level were measured at baseline, end of RT, 30 days, 3 and 6 months after RT. The generalized estimating equation (GEE) with intention to treat was applied. RESULTS: A significant difference in the fatigue mean between the end of RT and the baseline was found in patients of both groups. There was no adverse effect with the practice of Mat Pilates, and it was analyzed the reduction of the symptom pain after the end of RT in women of intervention group compared to the control. There was no significant effect on fatigue between the groups. Patients with severe fatigue after 3 and 6 months of RT reported a significantly lower level of physical activity in the last periods. CONCLUSION: Fatigue levels increased at the end of RT but returned to baseline values after 6 months. A lower level of physical activity was associated with severe fatigue symptoms. Mat Pilates was safe for these women and reduced the symptom pain after treatment, but it did not successfully reduce fatigue during adjuvant RT. REGISTRATION: NCT03333993.

Gestational protein restriction alters early amygdala neurochemistry in male offspring.

BACKGROUND: Gestational protein intake restriction-induced long-lasting harmful outcomes in the offspring's organs and systems. However, few studies have focused on this event's impact on the brain's structures and neurochemical compounds. AIM: The present study investigated the effects on the amygdala neurochemical composition and neuronal structure in gestational protein-restricted male rats' offspring. METHODS: Dams were maintained on isocaloric standard rodent laboratory chow with regular protein [NP, 17%] or low protein content [LP, 6%]. Total cells were quantified using the Isotropic fractionator method, Neuronal 3D reconstruction, and dendritic tree analysis using the Golgi-Cox technique. Western blot and high-performance liquid chromatography performed neurochemical studies. RESULTS: The gestational low-protein feeding offspring showed a significant decrease in birth weight up to day 14, associated with unaltered brain weight in youth or adult progenies. The amygdala cell numbers were unchanged, and the dendrites length and dendritic ramifications 3D analysis in LP compared to age-matched NP progeny. However, the current study shows reduced amygdala content of norepinephrine, epinephrine, and dopamine in LP progeny. These offspring observed a significant reduction in the amygdala glucocorticoid (GR) and mineralocorticoid (MR) receptor protein levels. Also corticotrophin-releasing factor (CRF) amygdala protein content was reduced in 7 and 14-day-old LP rats. CONCLUSION: The observed amygdala neurochemical changes may represent adaptation during embryonic development in response to elevated fetal exposure to maternal corticosteroid levels. In this way, gestational malnutrition stress can alter the amygdala's neurochemical content and may contribute to known behavioral changes induced by gestational protein restriction.

Impact on fatigue of different types of physical exercise during adjuvant chemotherapy and radiotherapy in breast cancer: systematic review and meta-analysis.

BACKGROUND: Physical exercise in women with breast cancer has shown benefits in reducing fatigue levels during adjuvant radiotherapy and chemotherapy. However, it is not well understood which type of exercise is more effective. OBJECTIVE: Assess the impact of different types of physical exercises on fatigue and which is the most effective in reducing this adverse effect during adjuvant treatment in breast cancer. METHODS: The inclusion criteria were randomized clinical trials of physical exercise in women diagnosed with breast cancer in stages I to IV, above 18 years, evaluating fatigue using validated questionnaires. The meta-analysis pooled results by standardized mean difference (SMD). RESULTS: A total of 20 randomized clinical trials involving 1793 participants revealed that the practice of physical exercise was statistically effective in reducing fatigue (SMD = - 0.46; 95% CI: - 0.66, - 0.27). Our analysis of subgroups suggests that the supervised combination of resistance training (RT) with aerobic training (AT) is the most effective physical exercise to reduce fatigue (SMD = - 1.13; 95% CI: - 2.09, - 0.17). The supervised RT was more effective (SMD = - 0.30; 95% CI: - 0.46, - 0.15) than supervised AT or mind-body techniques. It was observed that only during chemotherapy, women with breast cancer in the intervention groups showed a significant reduction in fatigue (SMD = - 0.38; 95% CI: - 0.55 to - 0.20). CONCLUSION: Physical exercise during adjuvant chemotherapy and/or radiotherapy in women with breast cancer can be considered beneficial in reducing fatigue, especially for women undergoing chemotherapy and for supervised training of resistance or combined RT and AT.

Hepatitis C virus eradication by direct-acting antiviral agents improves carotid atherosclerosis in patients with severe liver fibrosis.

BACKGROUND AND AIMS: Recent studies suggest an association between hepatitis C virus (HCV) infection and cardiovascular damage, including carotid atherosclerosis, with a possible effect of HCV clearance on cardiovascular outcomes. We aimed to examine whether HCV eradication by direct-acting antiviral agents (DAA) improves carotid atherosclerosis in HCV-infected patients with advanced fibrosis/compensated cirrhosis. MATERIALS AND METHODS: One hundred eighty-two consecutive patients with HCV and advanced fibrosis or compensated cirrhosis were evaluated. All patients underwent DAA-based antiviral therapy according to AISF/EASL guidelines. Intima-media thickness (IMT), carotid thickening (IMT ≥1 mm) and carotid plaques, defined as focal thickening of ≥1.5 mm at the level of the common carotid, were evaluated by ultrasonography (US) at baseline and 9-12 months after the end of therapy. Fifty-six percent of patients were male, mean age 63.1 ±â€¯10.4 years, and 65.9% had compensated cirrhosis. One in five had diabetes, 14.3% were obese, 41.8% had arterial hypertension and 35.2% were smokers. At baseline, mean IMT was 0.94 ±â€¯0.29 mm, 42.8% had IMT ≥1 mm, and 42.8% had carotid plaques. RESULTS: All patients achieved a 12-week sustained virological response. IMT significantly decreased from baseline to follow-up (0.94 ±â€¯0.29 mm vs. 0.81 ±â€¯0.27, p <0.001). Consistently, a significant reduction in the prevalence of patients with carotid thickening from baseline to follow-up was observed (42.8% vs. 17%, p <0.001), while no changes were reported for carotid plaques (42.8% vs. 47.8%, p = 0.34). These results were confirmed in subgroups of patients stratified for cardiovascular risk factors and liver disease severity. CONCLUSION: HCV eradication by DAA improves carotid atherosclerosis in patients with severe fibrosis with or without additional metabolic risk factors. The impact of this improvement in the atherosclerotic burden in terms of reduction of major cardiovascular outcomes is worth investigating in the long term. LAY SUMMARY: Hepatitis C virus eradication by direct-acting antiviral agents improves carotid atherosclerosis in patients with advanced fibrosis/compensated cirrhosis. The improvement in intima-media thickness and carotid thickening was confirmed after stratification for severity of liver disease and cardiovascular risk factors. Hepatitis C virus eradication by direct-acting antiviral agents also lead to improvement in glucose homeostasis and increased cholesterol levels.

Water and sodium in heart failure: a spotlight on congestion.

Despite all available therapies, the rates of hospitalization and death from heart failure (HF) remain unacceptably high. The most common reasons for hospital admission are symptoms related to congestion. During hospitalization, most patients respond well to standard therapy and are discharged with significantly improved symptoms. Post-discharge, many patients receive diligent and frequent follow-up. However, rehospitalization rates remain high. One potential explanation is a persistent failure by clinicians to adequately manage congestion in the outpatient setting. The failure to successfully manage these patients post-discharge may represent an unmet need to improve the way congestion is both recognized and treated. A primary aim of future HF management may be to improve clinical surveillance to prevent and manage chronic fluid overload while simultaneously maximizing the use of evidence-based therapies with proven long-term benefit. Improvement in cardiac function is the ultimate goal and maintenance of a "dry" clinical profile is important to prevent hospital admission and improve prognosis. This paper focuses on methods for monitoring congestion, and strategies for water and sodium management in the context of the complex interplay between the cardiac and renal systems. A rationale for improving recognition and treatment of congestion is also proposed.

Carotid atherosclerosis and chronic hepatitis C: a prospective study of risk associations.

UNLABELLED: There are contrasting results in studies of cardiovascular risk in patients with genotype 1 chronic hepatitis C (G1 CHC). We evaluated the prevalence of carotid atherosclerosis compared with a control population in order to assess the potential association between atherosclerosis, host and viral factors, and liver histological features. In all, 174 consecutive biopsy-proven G1 CHC patients were evaluated by anthropometric and metabolic measurements and 174 patients attending an outpatient cardiology unit were used as controls. Intima-media thickness (IMT) and carotid plaques, defined as focal thickening of >1.3 mm at the level of common carotid, were evaluated using ultrasonography. All G1 CHC biopsies were scored by one pathologist for staging and grading, and graded for steatosis. Carotid plaques were found in 73 (41.9%) G1 CHC patients compared with 40 (22.9%) control patients (P < 0.001). Similarly, G1 CHC patients had a greater IMT compared with control patients (1.04 ± 0.21 versus 0.90 ± 0.16; P < 0.001). Multivariate logistic regression analysis showed that older age (odds ratio [OR] 1.047, 95% confidence interval [CI]: 1.014-1.082, P = 0.005), and severe hepatic fibrosis (OR 2.177, 95% CI: 1.043-4.542, P = 0.03), were independently linked to the presence of carotid plaques. In patients ≤55 years, 15/67 cases with F0-F2 fibrosis (22.3%) had carotid plaques, compared with 11/21 (52.3%) with F3-F4 fibrosis (P = 0.008). By contrast, in patients >55 years the prevalence of carotid plaques was similar in those with or without severe fibrosis (25/43, 58.1% versus 22/43, 51.1%; P = 0.51). CONCLUSION: Severe hepatic fibrosis is associated with a high risk of early carotid atherosclerosis in G1 CHC patients.

Time-course morphological and functional disorders of the kidney induced by long-term high-fat diet intake in female rats.

BACKGROUND: Evidence is emerging that highlights the far-reaching consequences of a high-fat diet (HFD) on kidney morphology and function disorders. METHODS: The present study was performed on 3-, 5-, 7- and 9-week-old HFD female rats compared with the appropriate gender and age-matched animals. We evaluated the kidney expression of angiotensin type II receptor and fibrotic and epithelial-to-mesenchymal transition (EMT) markers, by immunoblotting and immunohistochemical and histological techniques, in parallel with kidney function. RESULTS: In the current study, the time-course HFD-treated group showed, by immunoblotting and immunohistochemical analysis, an early time-course increase in the expression of transforming growth factor ß-1 (TGFß-1) in the entire kidney of HFD-treated rats, compared with that observed in the control group. Simultaneously, the study shows a transient increase in the expression of ZEB2 in the HFD whole kidney accompanied by a fall in the E-cadherin expression and increased collagen and fibronectin deposition. A pronounced decrease in fractional urinary sodium excretion was also demonstrated in the long-term HFD-treated rats. The decreased FENa(+) was accompanied by a fall in FEPNa(+) and FEPPNa(+), which occurred in association with significantly decreased CCr and, certainly on the sodium-filtered load. The reduction in the glomerular filtration rate (GFR) occurred in parallel to proteinuria and glomerular desmin overexpression. CONCLUSIONS: The results of the current study suggest that podocyte injury in parallel with observed proteinuria and evidence of EMT transformation are associated with long-term loss of kidney function and renal sodium and water retention.

Troponin I release after intravenous treatment with high furosemide doses plus hypertonic saline solution in decompensated heart failure trial (Tra-HSS-Fur).

BACKGROUND: High values of cardiac troponin in acute decompensated congestive heart failure (ADHF) identify patients at higher risk and worsened prognosis. A cardiac troponin increase during therapy indicates the need for more appropriate intervention, aimed at compensating cardiac disease and effectively minimizing myocardial wall stress and subsequent cytolysis. This study evaluated the effects of an intravenous high dose of furosemide with (group A) or without small volume hypertonic saline solution (HSS) (group B) on myocardial cytolysis in patients with ADHF. METHODS: A total of 248 consecutive patients with ADHF (148 men, mean age 74.9 ± 10.9 years) were randomly assigned to group A or B. Plasma levels of cardiac troponin-I, brain natriuretic peptide, glomerular filtration rate by Modification of Diet in Renal Disease formula, bioelectrical impedance analysis measurements, and delta pressure/delta time (dP/dt) rate were observed on admission and discharge for all patients. RESULTS: We observed a significant reduction of cardiac troponin in both groups and a significant improvement in renal function, hydration state, pulmonary capillary wedge pressure (P < .0001), end diastolic volume (P < .01), ejection fraction (P < .01), and dP/dt (P < .004) in group A. We also observed a significant reduction in body weight (64.4 vs 75.8 kg) (P < .001), cardiac troponin I (0.02 vs 0.31 ng/mL) (P < .0001) and brain natriuretic peptide (542 vs 1,284 pg/mL) (P < .0001), and hospitalization time (6.25 vs 10.2 days) (P < .0001) in the HSS group. CONCLUSIONS: These data demonstrate that intravenous high doses of furosemide do not increase myocardial injury and, in addition, when associated to HSS, significantly reduce cardiac troponin I release. This behavior is mirrored by the achievement of improved hemodynamic compensation at echocardiography and body hydration normalization.

The glucocorticoid in acute decompensated heart failure: Dr Jekyll or Mr Hyde?

Glucocorticoid administration is not recommended in patients with heart failure because of its related sodium and fluid retention. However, previous experimental and clinical studies have demonstrated that glucocorticoids can also induce a diuretic effect and improve renal function in patients with acute decompensated heart failure (ADHF) with refractory diuretic resistance. We report the case of a 65-year-old man with a known diagnosis of aortic stenosis, systolic ventricular dysfunction, and chronic obstructive pulmonary disease who was admitted for ADHF. After 3 days, during which resistance to conventional therapy was observed, intravenous methylprednisolone (60 mg/d) was added to ongoing medical treatment. Three days after the onset of glucocorticoid therapy, daily urine volume progressively increased (up to 5.8 L/d). Concurrently, signs and symptoms of congestion improved, the weight and brain natriuretic peptide plasma levels decreased (−7 kg and −46%, respectively) and glomerular filtration rate increased (+26%). Bioimpedance vector analysis showed a net reduction of fluid content (from 88.4% to 73.6% of hydration at discharge). In conclusion, this case report suggests that in a patient with ADHF and congestion resistant to diuretic therapy, glucocorticoid administration is safe and associated with improvement in congestion, neurohormonal status, and renal function. These data support the possible usefulness of glucocorticoids in this setting.

Large hiatal hernia at chest radiography in a woman with cardiorespiratory symptoms.

Hiatal hernia (HH) is a frequent entity. Rarely, it may exert a wide spectrum of clinical presentations mimicking acute cardiovascular events such as angina-like chest pain until manifestations of cardiac compression that can include postprandial syncope, exercise intolerance, respiratory function, recurrent acute heart failure, and hemodynamic collapse. A 69-year-old woman presented to the emergency department complaining of fatigue on exertion, cough, and episodes of restrosternal pain with less than 1 hour of duration. Her medical history only included some episodes of bronchitis and no history of hypertension. The 12-lead electrocardiogram demonstrated sinus rhythm with right bundle-branch block. Laboratory tests, including cardiac troponin I, were within normal reference values. Chest radiography showed no significant pulmonary alterations and revealed in mediastinum a huge abnormal shadow overlapping the right heart compatible with a gastric bubble.The gastroscopy confirmed a large HH. A 2-dimensional transthoracic echocardiogram, using all standard and modified apical and parasternal views, revealed an echolucent mass, compatible with HH, compressing the right atrium. Also, it showed an altered left ventricular relaxation and a mild increase of pulmonary artery pressure (35 mm Hg). Spirometry showed a mild obstruction of the small airways, whereas coronary angiography showed normal coronary arteries. We concluded that the patient's symptomatology was related to the compressive effects of the large hiatal ernia, a neglected cause of cardiorespiratory symptoms. The surgical repair of HH was indicated.

Changes in estimating echocardiography pulmonary capillary wedge pressure after hypersaline plus furosemide versus furosemide alone in decompensated heart failure.

BACKGROUND: The aim of the study was to verify the effects of hypertonic saline solution (HSS) plus a high furosemide dose and light restriction of sodium intake compared with a high-dose infusion of furosemide alone on pulmonary capillary wedge pressure (PCWP), as determined by Doppler echocardiography and tissue Doppler imaging in patients suffering from decompensated heart failure. METHODS AND RESULTS: Consecutive patients in New York Heart Association functional class IV, unresponsive to oral high doses of furosemide up to 250-500 mg/d and/or combinations of diuretics, with ejection fraction <40%, serum creatinine <2 mg/dL, blood urea nitrogen ≤60 mg/dL, reduced urinary volume (<500 mL/24 h), and low natriuresis (<60 mEq/24 h) were randomized into 2 groups (double blind). The first group received a furosemide infusion (250 mg) plus HSS (150 mL 3.0% Na) bid and light Na restriction (120 mmol), and the second group received furosemide infusion (250 mg) twice daily, and low Na diet (80 mmol). The fluid intake of both groups was restricted (1 L/d). Body weight, whole-body bioelectrical impedance analysis (BIA), 24-hour urinary volume, and serum and urinary laboratory parameters were measured daily. Estimations of echocardiographic PCWP (Echo-PCWP) were detected on entry, 1 hour after concluding the initial treatment, and 6 days thereafter. A total of 133 patients (47 women and 86 men), aged 65-82 years, met the entry criteria.The HSS group revealed a significant increase in daily diuresis, natriuresis, and serum sodium compared with the furosemide group. Six days after treatment, renal function was significantly improved in the HSS group. Both groups showed a significant reduction in Echo-PCWP, but the HHS group revealed a faster reduction and significant lower values at 6 days compared with the group taking furosemide alone. We observed a positive correlation between values of Echo-PCWP and BNP and an inverse correlation between BIA parameters and Echo-PCWP. CONCLUSIONS: Our data show that the combination of high diuretic dose and HSS infusion plus light restriction in dietary sodium intake determine a more rapid and significant hemodynamic stabilization through the improvement of echo-PCWP, BNP levels, and BIA parameters than the group treated without HSS.

Severe Brochostenosis by Oral Propafenone Immediately After Commencing Treatment.

Propafenone is a membrane-stabilizing agent belonging to a subgroup of the Vaughan Williams class I antidysrhythmic agents, structurally resembling propranolol and characterized by weaker beta-blocking activity. Despite respiratory complications having been reported as examples of side effects, very few reports have been published in the literature.We describe the case of an elderly woman with a history of hypertension and allergy to Parietaria, grass, olive, mites, and with periodic asthmatic manifestations, for whom the administration of oral propafenone for recurrent supraventricular dysrhythmia was associated with the sudden onset of severe bronchostenosis.A 78-year-old woman was frequently admitted to the Emergency Department for a recurrent supraventricular tachycardia, which was treated initially with veramapil and thereafter with ivabradin. During her last visit to the cardiologist, she was prescribed propafenone (150 mg, 3 times a day) in place of ivabradin. After the administration of the second dose on the first day of the therapy, the patient began to complain of the onset of progressively severe dyspnea at rest. In the Emergency Department, respiratory auscultation showed diffuse rhonchi, wheezing, and rales; and arterial pressure was 200/100 mm Hg. Hemogasanalysis revealed hypoxemia, respiratory acidosis with 83% of O2-saturation. Emergency treatment with O2 therapy, methylprednisolone intravenous, furosemide, and then salbutamol was also started; the electrocardiogram only showed sinusal tachycardia. Results of laboratory examinations, including a white cell count and cardiac enzymes, were within the normal range. The patient achieved good respiratory function, after a period of 3 days.This report describes that even a relatively small dose of oral propafenone after commencing treatment can have a severe effect in exacerbating the obstruction of the airways in a susceptible subject. The likely mechanisms are an allergic reaction or a direct bronchospastic effect. Considering the recognized asthmogenicity of propafenone due to beta-blocker activity, we suggest that the cardiologist always refer to the patient's medical history before prescribing this drug, which is capable of producing notable side effects in predisposed individuals, beginning the eventual administration in the hospital setting. The use of bronchial provocation test allows the selection of inclined patients, thus reducing the risk of bronchospasm.

Naïve hepatitis B e antigen-negative chronic hepatitis B patients are at risk of carotid atherosclerosis: A prospective study.

BACKGROUND: There is an increased risk of atherosclerosis in patients with chronic hepatitis C or human immunodeficiency virus, but there is scarce data on hepatitis B virus infection. The hypothesis of this study is that hepatitis B virus infection increases the risk of carotid plaques and subclinical atherosclerosis in naïve hepatitis B e antigen (HBeAg) negative subjects. AIM: To assess the rate of carotid plaques and subclinical atherosclerosis in naïve HBeAg negative subjects in comparison with a cohort of healthy controls. METHODS: Prospective case-control collaborative study conducted in two tertiary hospitals. Four hundred and two subjects prospectively recruited at the outpatient clinic were included from May 2016 to April 2017: 201 naïve HBeAg-negative hepatitis B virus-infected [49 chronic hepatitis B (CHB) and 152 inactive carriers(ICs)] and 201 healthy controls. Anthropomorphic and metabolic measures, liver stiffness and carotid Doppler ultrasound were performed. Subclinical atherosclerosis was established on an intima-media thickness increase of ≥1.2 mm and/or the presence of carotid plaques. Normally distributed quantitative variables were compared with the Student t test and those with a non-normal distribution with the Mann-Whitney U test. Categorical variables were compared between groups using the χ 2 or Fisher exact test. RESULTS: Carotid plaques were found more often in CHB (32.7%) than ICs (17.1%) or controls (18.4%) (P = 0.048). Subclinical atherosclerosis was also increased in CHB (40.8%) vsICs (19.1%) or controls (19.4%) (P = 0.003). No differences in the risk of atherosclerosis were observed between controls and ICs. The factors independently associated with the presence of carotid plaques were age [odds ratio(OR) 1.43, P < 0.001] and CHB (OR 1.18, P = 0.004) and for subclinical atherosclerosis, age (OR 1.45, P < 0.001), CHB (OR 1.23, P < 0.001) and diabetes (OR 1.13, P = 0.028). In the subset of young subjects (< 50 years), carotid plaques (12.5% vs 1.1%, P = 0.027) and subclinical atherosclerosis (12.5% vs 2.2%, P = 0.058) were more frequent among CHB than ICs. CONCLUSION: Untreated HBeAg-negative CHB is an independent risk factor for carotid plaques and subclinical atherosclerosis, while ICs present a similar risk to controls.

Sudden severe abdominal pain after a single low dose of paracetamol/codein in a cholecystectomized patient: learning from a case report.

We report the case of an elderly patient with diastolic heart failure and renal insufficiency admitted to hospital as he complained of having a history of hypogastric pain and dysuria without fever due to renal lithiasis and urinary infection. Because the pain was persistence, and considering the presence of renal dysfunction, it was administered a single low dose of paracetamol/codein (500/30 mg). After about 1 hour of the administration, he suddenly complained of the onset of a lancinating epigastric pain radiating to the whole abdomen and retrosternum accompanied by nausea. The electrocardiogram (EKG) was negative for myocardial infarction and computed tomography excluded aortic dissection and other causes of acute abdomen. Laboratory tests showed instead liver and pancreatic damage. The symptomatology was relieved 3 hours later of the onset after antispastic treatment with anticholinergics (floroglucine). The likely underlying pathophysiological mechanism is the codein-induced spasm of the sphincter of Oddi combined with dysfunction of the same sphincter and reduced bile storage capacity related to a previous cholecystectomy. When a similar event does not regress, it may lead to more severe conditions such as acute pancreatitis. Since codein is a widely used drug, this report may suggest cholecystectomy as a contraindication during administration for the risk of occurrence of these complications.

Long-term effects of dietary sodium intake on cytokines and neurohormonal activation in patients with recently compensated congestive heart failure.

BACKGROUND: A growing body of evidence suggests that the fluid accumulation plays a key role in the pathophysiology of heart failure (HF) and that the inflammatory and neurohormonal activation contribute strongly to the progression of this disorder. METHODS AND RESULTS: The study evaluated the long-term effects of 2 different sodium diets on cytokines neurohormones, body hydration and clinical outcome in compensated HF outpatients (New York Heart Association Class II). A total of 173 patients (105 males, mean age 72.5+/-7) recently hospitalized for worsening advanced HF and discharged in normal hydration and in clinical compensation were randomized in 2 groups (double blind). In Group 1, 86 patients received a moderate restriction in sodium (120mmol to 2.8g/day) plus oral furosemide (125 to 250mg bid); in Group 2, 87 patients: received a low-sodium diet (80mmol to 1.8g/day) plus oral furosemide (125 to 250mg bid). Both groups were followed for 12 months and the treatment was associated with a drink intake of 1000mL daily. Neurohormonal (brain natriuretic peptide, aldosterone, plasma rennin activity) and cytokines values (tumor necrosis factor-alpha, interleukin-6) were significantly reduced with a significant increase of the anti-inflammatory cytokine interleukin-10 at 12 months in normal, P < .0001) than low-sodium group. The low-sodium diet showed a significant activation of neurohormones and cytokines and worsening the body hydration, whereas moderate sodium restriction maintained dry weigh and improved outcome in the long term. CONCLUSIONS: Our results appear to suggest a surprising efficacy of a new strategy to improve the chronic diuretic response by increasing Na intake and limiting fluid intake. This counterintuitive approach underlines the need for a better understanding of factors that regulate sodium and water handling in chronic congestive HF. A larger sample of patients and further studies are required to evaluate whether this is due to the high dose of diuretic used or the low-sodium diet.

Comparison of ivabradine versus metoprolol in early phases of reperfused anterior myocardial infarction with impaired left ventricular function: preliminary findings.

BACKGROUND: beta-blockers in ST-segment elevation myocardial infarction (STEMI) are indicated for patients without a contraindication, particularly in patients with high heart rates (HR) or blood pressures. Epidemiological studies have shown that elevated HR represents a risk factor for cardiovascular morbidity. The study investigates the feasibility, tolerability, and the effects after 30 days of follow-up of ivabradine (IVA) versus metoprolol (METO) in early phases of anterior STEMI reperfused by percutaneous coronary intervention (PCI). METHODS AND RESULTS: Patients with a first anterior STEMI, Killip class I-II, an acceptable echocardiographic window, and admitted within 4hours of the onset of symptoms, with an ejection fraction <50%. METO or IVA, 12hours after PCI (double blind), were administered twice per day. Blood pressure (BP), heart rate (HR), electrocardiogram (ECG), and laboratory parameters were monitored during the study. At entry, day 10, day 30, and day 60, by echocardiography, the ESV, EDV, E/A ratio, E wave deceleration time, isovolumetric relaxation time were measured. A total of 155 (50 females, 105 males) patients were randomized in 2 groups: a group received METO (76 patients) 12hours after PCI and a group received IVA (79 patients) 12hours after PCI. The 2 groups were similar for clinical characteristics. No difference was evidenced in HR, systolic blood pressure, diastolic blood pressure, age (range, 39-73 years), sex, ejection fraction (EF), creatine kinase peak, between the 2 groups at entry. Both groups were similar for time to angiography and interventional procedures and number of vessels diseased. IVA group: the 79 patients showed 2 side effects and 5 readmissions: 4 for ischemic events and 1 for heart failure, and 1 sudden death; METO group: the 76 patients had 4 ischemic events, 2 side effects, and 1 patient died during re-acute MI (intrastent thrombosis) and 8 readmissions for heart failure signs. The systolic blood pressure and diastolic blood pressure showed a significant reduction in both groups, P < .0001, respectively), and significant lower values were observed in METO group, P=.0001). The HR was significantly reduced in both groups, P < .0001). IVA group showed a significant increase in EF, P=.0001, with concomitant reduction in ESV and EDV (P=.0001, and .048, respectively). The diastolic parameters were similar in both groups during study period. CONCLUSIONS: Our results suggest that ivabradine may be administered early (12hours after PCI) to patients with successful PCI for anterior STEMI with an impaired left ventricular function and high HR and sinus rhythm. A larger sample of patients and further studies are required to evaluate the effects of ivabradine on clinical end points.

One-year renal and cardiac effects of bisoprolol versus losartan in recently diagnosed hypertensive patients: a randomized, double-blind study.

BACKGROUND AND OBJECTIVES: Hypertension is a significant cause of chronic renal injury and its effective treatment is capable of reducing the rate of renal failure. beta-Adrenoceptor antagonists (beta-blockers) have been reported to induce a deterioration in renal function, while several data have indicated a renoprotective effect of treatment with the angiotensin II type 1 receptor antagonist losartan. Previous studies of the interaction between the selective beta(1)-blocker bisoprolol and kidney function were performed only for short- and medium-term periods. The aim of this study was to compare the antihypertensive efficacy and renal and cardiac haemodynamic effects of bisoprolol with those of losartan over a 1-year time period in patients with essential hypertension. METHODS: Seventy-two patients (40 males) with recently diagnosed uncomplicated (European Society of Hypertension [ESH] criteria stage 1-2) hypertension (mean +/- SD age 52 +/- 12 years) were enrolled in the study. After a run-in period of 14 days on placebo, the patients were randomized in a double-blind, prospective study to receive either bisoprolol 5 mg or losartan 50 mg, administered once daily for 1 year. At recruitment and 12 months after treatment, cardiac output and renal haemodynamics and function were evaluated by echocardiography and radionuclide studies, respectively. RESULTS: There were no significant differences in baseline clinical data, including glomerular filtration rate and blood pressure, between the two treatment groups. At 1 year, blood pressure had decreased significantly (p < 0.001) with both treatments, and heart rate was reduced only in the group taking bisoprolol. The long-term effects on renal haemodynamics and cardiac function were similar with both drugs, the only change being a significant reduction in the filtration fraction for each group. CONCLUSIONS: These data suggest that both bisoprolol and losartan are effective agents for the treatment of patients with recently diagnosed ESH stage 1-2 hypertension. Over a 1-year period, both agents maintained good renal and cardiac performance and haemodynamics.

Right ventricular diameter predicts all-cause mortality in heart failure with preserved ejection fraction.

Left ventricular ejection fraction (EF) is helpful to differentiate heart failure (HF) phenotype in clinical practice. The aim of the study was to identify simple echocardiographic predictors of post-discharge all-cause mortality in hospitalized HF patients. Patients with acute HF (75 ± 9.8 years), classified in preserved (≥ 50%) and reduced (< 50%) EF (HFpEF and HFrEF, respectively), were enrolled. The mean follow-up period was of 25.4 months. Patients definitively analyzed were 135. At multivariate Cox model, right ventricular diameter (RVd), inferior vena cava diameter (IVCd) and blood urea nitrogen (BUN) resulted to be significantly associated with all-cause mortality in HFpEF (HR 2.4, p = 0.04; HR 1.06, p = 0.02; HR 1.02, p = 0.01), whereas, left atrial volume (LAV) was significantly associated with mortality in HFrEF (HR 1.06, p = 0.006). Excluding LAV from the model, only COPD remained an independent predictor of all-cause mortality (HR 2.15, p = 0.04) in HFrEF. At Kaplan-Meier analysis, no differences of survival between HFrEF and HFpEF were found, however, significantly increased all-cause mortality for higher values of basal-RVd, BUN, and IVCd (log-rank p = 0.0065, 0.0063, 0.0005) in HFpEF, and for COPD and higher LAV (log-rank p = 0.0046, p = 0.033) in HFrEF. These data are indicative that in patients hospitalized with HF, EF is not a suitable predictor of long-term all-cause mortality, whereas, right ventricular volumetric remodeling and IVCd have a prognostic role in HFpEF as well as LAV in HFrEF. Our study suggests that besides EF, other echocardiographic parameters are helpful to optimize the phenotyping and prognostic stratification of HF.

Inflammation and Aortic Pulse Wave Velocity: A Multicenter Longitudinal Study in Patients With Inflammatory Bowel Disease.

Background Inflammatory bowel disease ( IBD ) is characterized by a low prevalence of traditional risk factors, an increased aortic pulse-wave velocity ( aPWV ), and an excess of cardiovascular events. We have previously hypothesized that the cardiovascular risk excess reported in these patients could be explained by chronic inflammation. Here, we tested the hypothesis that chronic inflammation is responsible for the increased aPWV previously reported in IBD patients and that anti-TNFa (anti-tumor necrosis factor-alpha) therapy reduce aPWV in these patients. Methods and Results This was a multicenter longitudinal study. We enrolled 334 patients: 82 patients with ulcerative colitis, 85 patients with Crohn disease, and 167 healthy control subjects matched for age, sex, and mean blood pressure, from 3 centers in Europe, and followed them for 4 years (range, 2.5-5.7 years). At baseline, IBD patients had higher aPWV than controls. IBD patients in remission and those treated with anti-TNFa during follow-up experienced an aortic destiffening, whereas aPWV increased in those with active disease and those treated with salicylates ( P=0.01). Disease duration ( P=0.02) was associated with aortic stiffening as was, in patients with ulcerative colitis, high-sensitivity C-reactive protein during follow-up ( P=0.02). All these results were confirmed after adjustment for major confounders. Finally, the duration of anti-TNFa therapy was not associated with the magnitude of the reduction in aPWV at the end of follow-up ( P=0.85). Conclusions Long-term anti-TNFa therapy reduces aPWV , an established surrogate measure of cardiovascular risk, in patients with IBD . This suggests that effective control of inflammation may reduce cardiovascular risk in these patients.
