Occult HBV infection may negatively impact on drug survival in patients with rheumatoid arthritis on treatment with a first biologic drug. An appraisal from the Biologic Apulian Registry (BIOPURE).

We performed a retrospective analysis to evaluate the survival on first line biologic drug of rheumatoid arthritis (RA) patients with potential occult HBV infection (pOBI). We analysed longitudinal data of 486 consecutive RA patients starting a first biological drug in a time frame from 1st January 2008 to 31st December 2014. Demographic and disease related characteristics were collected at baseline and at the last observation visit. Baseline serological markers of HBV infection and causes of treatment discontinuation were also recorded. Primary endpoint was the influence of pOBI on drug survival, estimated by Kaplan-Meier life table analysis. Estimates hazard ratios (HRs) of drug discontinuation, adjusted for disease characteristics, biological drug class and HBcAb status were computed by Cox-regression models. The retention rate was significantly lower in pOBI positive patients (58.2%) when compared to pOBI negative ones (67.8%) and this data was confirmed also when only discontinuation due to ineffectiveness was considered (pOBI positive 66.4% vs pOBI negative 75.3%, long rank 7.93, p=0.005). Cox regression models showed a significant association between HBcAb-neg (HR 0.58, 0.41-0.84), higher ESR-DAS28 at baseline (HR 1.07, 1.03-1.11) or RF/ACPA-neg (HR 1.46, 1.04-2.06) and drug discontinuation. Occult HBV infection seems to influence negatively the effectiveness of biological therapies in RA patients.

Effect of resistant starch on the intestinal health of old dogs: fermentation products and histological features of the intestinal mucosa.

The effects of resistant starch (RS) intake on nutrient digestibility, microbial fermentation products, faecal IgA, faecal pH, and histological features of the intestinal mucosa of old dogs were evaluated. The same formulation was extruded in two different conditions: one to obtain elevated starch cooking degree with low RS content (0.21%) and the other lower starch cooking with high RS content (1.46%). Eight geriatric Beagles (11.5 ± 0.38 years old) were fed each diet for 61 days in a crossover design. Food intake, nutrient digestibility, fermentation products, faecal pH, and faecal IgA were examined via variance analysis. Histological results of intestinal biopsies were assessed via Wilcoxon test for paired data. The morphometric characteristics of large intestine crypts were evaluated via paired t tests (p < .05). Protein, fat, and energy digestibilities were higher for the low-RS diet (p < .05). Dogs receiving the high-RS diet had lower faecal pH and higher values for propionate, butyrate, total volatile fatty acids, and lactate (p < .05). No differences between diets were found in the histological parameters of the gut mucosa, and only a tendency for deeper crypts in the descending colon was observed for dogs fed the high-RS diet (p = .083). The intake of a corn-based kibble diet manufactured with coarse ground raw material and low starch gelatinization to obtain 1.4% of RS affected microbial fermentation products and faecal pH and tended to increase crypt depth in the descending colon of old dogs.

New studies of second and fourth digit ratio as a morphogenetic trait in subjects with congenital adrenal hyperplasia.

OBJECTIVES: Congenital adrenal hyperplasia (CAH) is a disease that occurs during fetal development and can lead to virilization in females or death in newborn males if not discovered early in life. Because of this there is a need to seek morphological markers in order to help diagnose the disease. In order to test the hypothesis that prenatal hormones can affect the sexual dimorphic pattern 2D:4D digit ratio in individual with CAH, the aim of this study was to compare the digit ratio in female and male patients with CAH and control subjects. METHODS: The 2D:4D ratios in both hands of 40 patients (31 females-46, XX, and 9 males-46, XY) were compared with the measures of control individuals without CAH (100 males and 100 females). RESULTS: Females with CAH showed 2D:4D ratios typical of male controls (0.950 and 0.947) in both hands (P < 0.001). In CAH males the left hand 2D:4D ratio (0.983) was statistically different from that of male controls (P < 0.05). CONCLUSIONS: These finding support the idea that sexual dimorphism in skeletal development in early fetal life is associated with differences between the exposure to androgens in males and females, and significant differences associated with adrenal hyperplasia. Although the effects of prenatal androgens on skeletal developmental are supported by numerous studies, further investigation is yet required to clarify the disease and establish the digit ratio as a biomarker for CAH.

'Scarless reverse umbilicoplasty': A new technique of umbilical transposition in abdominoplasty.

INTRODUCTION: The navel plays a major role in the aesthetics of the abdomen. A navel that is abnormally shaped, malpositioned or has evident scarring may compromise the outcome of an otherwise well-executed full abdominoplasty. The aim of the technique in question is to recreate a navel that looks natural, with no visible scar, and that is properly positioned. MATERIALS AND METHODS: The technique was performed in 147 abdominoplasties of patients of both sexes (123 females and 24 males), with an average age of 35 years and a mean BMI of 24 kg/m2. The procedure involves the creation of a navel of reduced size, 10 × 5 mm, and its inset in the abdominal wall. Subsequently, the as-yet-not sutured abdominal flap is extended caudally to determine the point of projection of the navel. The abdominal skin is marked, the flap is reversed and an internal suture is carried out. RESULTS: The appearance of the navel is aesthetically pleasant and natural looking and with no visible scarring. In addition, the position of the umbilicus is always correct. At the two-year follow-up, the results remain stable. No major complication occurred. CONCLUSIONS: The technique allows for the attainment of an extremely natural looking navel that satisfies the aesthetic criteria of attractiveness without visible scarring. The navel is always correctly positioned, without requiring measurements during surgery. The procedure is rapid, and although it does require a short learning curve, the results are extremely aesthetically pleasing and reproducible. The patient satisfaction rate is extremely high.

Role of sildenafil in acute posttransplant right ventricular dysfunction: successful experience in 13 consecutive patients.

BACKGROUND: Superimposed acute right ventricular dysfunction in the setting of preexisting pulmonary hypertension is a nearly fatal complication after heart transplantation. The optimal treatment modality remains a matter of debate. Recently, sildenafil citrate, a nonselective pulmonary vasodilator, has gained popularity in the treatment of pulmonary hypertension in transplant candidates. METHODS: Herein we have presented a series of 13 patients in whom sildenafil was used to treat right ventricular dysfunction and pulmonary hypertension as detected by transesophageal echocardiography and Swan-Ganz right heart catheterization after heart transplant. Their characteristics were mean age 49+/-11.4 years; 38.4% with previous cardiac procedures, 30.8% status I, basal pulmonary vascular resistance index 10.4+/-4.6 WoodU, mean transpulmonary gradient 18.7+/-5.4 mmHg. In addition to conventional inodilator support, we administered 1 to 3 mg per kilogram of sildenafil. Complete hemodynamic measurements were obtained before and after the institution of the therapy and at 1-month follow-up. RESULTS: Within the first 72 hours, acute right ventricular dysfunction resolved in all cases without untoward side effects or significant systemic impact. Sildenafil significantly decreased the transpulmonary gradient and pulmonary vascular resistance index relative to baseline values; 5.6+/-1.82 versus 10.4+/-4.6 WU, (P< .05), 13.5+/-3.4 mm Hg versus 18.7+/-5.4 mm Hg (P< .05), respectively. Improved indices of right ventricular function were observed on echocardiographic monitoring. After 1 month, sildenafil treatment was discontinued. CONCLUSION: Management of acute right ventricular dysfunction in heart transplant recipients with pulmonary hypertension using sildenafil proved safe and effective.

In vitro cultured progenitors and precursors of cardiac cell lineages from human normal and post-ischemic hearts.

The demonstration of the presence of dividing primitive cells in damaged hearts has sparked increased interest about myocardium regenerative processes. We examined the rate and the differentiation of in vitro cultured resident cardiac primitive cells obtained from pathological and normal human hearts in order to evaluate the activation of progenitors and precursors of cardiac cell lineages in post-ischemic human hearts. The precursors and progenitors of cardiomyocyte, smooth muscle and endothelial lineage were identified by immunocytochemistry and the expression of characteristic markers was studied by western blot and RT-PCR. The amount of proteins characteristic for cardiac cells (alpha-SA and MHC, VEGFR-2 and FVIII, SMA for the precursors of cardiomyocytes, endothelial and smooth muscle cells, respectively) inclines toward an increase in both alpha-SA and MHC. The increased levels of FVIII and VEGFR2 are statistically significant, suggesting an important re-activation of neoangiogenesis. At the same time, the augmented expression of mRNA for Nkx 2.5, the trascriptional factor for cardiomyocyte differentiation, confirms the persistence of differentiative processes in terminally injured hearts. Our study would appear to confirm the activation of human heart regeneration potential in pathological conditions and the ability of its primitive cells to maintain their proliferative capability in vitro. The cardiac cell isolation method we used could be useful in the future for studying modifications to the microenvironment that positively influence cardiac primitive cell differentiation or inhibit, or retard, the pathological remodeling and functional degradation of the heart.

Preclinical activity of CPI-0610, a novel small-molecule bromodomain and extra-terminal protein inhibitor in the therapy of multiple myeloma.

Inhibition of the bromodomain and extra-terminal (BET) proteins is a promising therapeutic strategy for various hematologic cancers. Previous studies suggest that BET inhibitors constrain tumor cell proliferation and survival mainly through the suppression of MYC transcription and activity. However, suppression of the transcription of additional genes also contributes to the antitumor activity of BET inhibitors but is less well understood. Here we examined the therapeutic potential of CPI-0610, a potent BET inhibitor currently undergoing phase I clinical testing, in multiple myeloma (MM). CPI-0610 displays potent cytotoxicity against MM cell lines and patient-derived MM cells through G1 cell cycle arrest and caspase-dependent apoptosis. CPI-0610-mediated BET inhibition overcomes the protective effects conferred by cytokines and bone marrow stromal cells. We also confirmed the in vivo efficacy of CPI-0610 in a MM xenograft mouse model. Our study found IKZF1 and IRF4 to be among the primary targets of CPI-0610, along with MYC. Given that immunomodulatory drugs (IMiDs) stabilize cereblon and facilitate Ikaros degradation in MM cells, we combined it with CPI-0610. Combination studies of CPI-0610 with IMiDs show in vitro synergism, in part due to concomitant suppression of IKZF1, IRF4 and MYC, providing a rationale for clinical testing of this drug combination in MM patients.

Acid-base balance in heart failure.

In end-stage heart failure, various acid-base disorders can be discovered due to the renal loss of hydrogen ions and hydrogen ion movements into cells, the reduction of the effective circulating volume, hypoxemia and renal failure. This justifies the occurrence of metabolic alkalosis, metabolic acidosis, respiratory alkalosis, as well as respiratory acidosis alone or in combination. Several studies have been published on the acid-base state in heart failure. In a 1951 study, Squires et al analyzed the distribution of body fluid in congestive heart failure by taking into consideration the abnormalities in serum electrolyte concentration and in acid-base equilibrium. A recent study by Milionis et al, analyzed 86 patients with congestive heart failure receiving conventional treatment; the majority of these patients exhibited hypokalemia, hyponatremia, hypocalcemia and hypophosphatemia. Disorders in acid-base balance were noted in 37.2% of patients. In a recent study, 70 patients with severe congestive heart failure before heart transplantation showed high-normal pH, slightly reduced pCO 2 and a slight loss of hydrogen ions. After heart transplantation, stability of blood pH and hydrogen ion concentrations was found. In contrast, bicarbonate and pCO 2 increased significantly. The data led us to formulate the diagnosis of a mixed acid-base disorder that includes respiratory alkalosis and metabolic alkalosis before heart transplantation. In heart failure, the presence of acid-base imbalance associated with the activation of mechanisms that lead to salt and water retention reveals evidence concerning the pivotal role of the kidney in determining the outcome of these patients.

Pim2 is important for regulating DNA damage response in multiple myeloma cells.

Pan proviral integrations of Moloney virus (PIM) inhibition in multiple myeloma (MM) results in reduced cell viability in tested human-derived MM cell lines and reduces tumor burden in xenograft mouse models, making PIMs important therapeutic targets for the disease. PIM kinase inhibitors are currently being tested clinically in MM. We sought to elucidate the role of the various PIMs in MM. Our data demonstrate that Pim2 has a significant role in MM cell cytotoxicity. Our data provide evidence for a novel role for Pim2 in the regulation of the DNA damage response (DDR). Knockdown of Pim2 upregulates several downstream DDR markers, mimicking the effects of doxorubicin (Dox) treatment of MM cells, and suggesting a role for the kinase as a negative regulator of this pathway. Dox-induced DNA damage results in a decrease in Pim2 levels, placing the kinase directly downstream of the site of Dox-DNA binding. Overexpression of Pim2 confers a slight survival advantage against Dox through antiapoptotic activity, further underscoring its relevance in the DDR pathway. These data provide insights into a novel mechanism of PIM kinase activity and provide the framework for designing therapeutic approaches in MM.

Dose-dependent fetal complications of warfarin in pregnant women with mechanical heart valves.

OBJECTIVES: The purpose of this study was to assess the incidence of warfarin fetal complications and whether they are dose-dependent. BACKGROUND: Gravid patients with mechanical heart valves require long-term anticoagulant therapy. Controversy exists concerning the appropriate treatment of these patients. METHODS: Forty-three women on warfarin carrying out 58 pregnancies were studied. For each patient with full-term pregnancy a caesarian section was scheduled for the 38th week during brief warfarin discontinuation. Maternal and fetal complications were evaluated. Fetal complications were divided according to the warfarin dosage < or = 5 mg and > 5 mg necessary to keep an international normalized ratio (INR) of 2.5 to 3.5, and analyzed subsequently. RESULTS: A total of 58 pregnancies were observed: 31 healthy babies (30 full term, 1 premature) and 27 fetal complications (22 spontaneous abortions, 2 warfarin embryopathies, 1 stillbirth, 1 ventricular septal defect, 1 growth retardation) were recorded. Two maternal valve thromboses occurred. No fetal or maternal bleeding was observed during caesarian sections or premature vaginal delivery. Patients whose warfarin doses during pregnancy were > 5 mg had 22 fetal complications, whereas those taking a dose < or = 5 mg had only five fetal complications (p = 0.0001). For an increase of the warfarin dose there was a substantially increased probability of fetal complications (p < 0.0001; p < 0.7316). CONCLUSIONS: There is a close dependency between warfarin dosage and fetal complications. Patients on warfarin anticoagulation may be delivered by planned caesarian section at the 38th week while briefly interrupting anticoagulation.

The risk of stroke following CABG: one possible strategy to reduce it?

OBJECTIVE: Stroke remains a devastating complication of coronary artery bypass grafting (CABG): we evaluated whether a more aggressive diagnostic and therapeutic approach can reduce its incidence. METHODS: Between January 1998 and January 2002, 1388 consecutive patients underwent isolated on pump CABG with blood cardioplegia. Among the first 627 patients (Group A), Echo-Doppler study (DS) was performed only in selected patients (58) with history of cerebrovascular disease (CVD) and/or carotid bruit; in 761 patients (Group B), DS was performed routinely. Carotid endarterectomy (CEA) was performed in 45 patients in Group A associated to CABG during cardiopulmonary bypass (CPB) and in 90 patients in Group B under local anaesthesia before CABG. Brain CT scan was performed in all cases with postoperative neurological symptoms. RESULTS: The two groups were homogeneous for age, sex, associated diseases, history of CVD, number of graft and CPB time. There were no differences in terms of hospital mortality between Group A (22/627: 3.5%) and Group B (21/761: 2.75%); p=0.5. Postoperative stroke was observed in 24/627 (3.82%) patients of Group A and in 2/761 (0.26%) of Group B (p<0.001). Hospital mortality for stroke was higher in Group A (12/627: 1.91%) than in Group B (0/761; p<0.001) as well as the incidence of non-fatal stroke (Group A 12/627: 1.91% versus Group B 2/761: 0.26% p=0.006). CONCLUSIONS: Preoperative DS, performed in all cases of CABG, followed by CEA under local anaesthesia in patients with critical carotid stenosis reduces the incidence of postoperative stroke.

Role of immunosuppressive regimen on the incidence and characteristics of cytomegalovirus infection in heart transplantation: a single-center experience with preemptive therapy.

OBJECTIVE: This retrospective single-center report sought to evaluate the relation of immunosuppressive regimen with the incidence and characteristics of cytomegalovirus (CMV) infection from 1999 to 2003. PATIENTS AND METHODS: Immunosuppression consisted of cyclosporine microemulsion (Neoral), azathioprine (AZA), and prednisolone associated with either thymoglobulin or ATG high-dosage induction from 1999 to 2000 (AZA, 64 patients [AZA-Thymo = 38 patients and AZA-ATG 26 patients]), or cyclosporine microemulsion (Neoral), mycophenolate mofetil (MMF), and prednisolone with low-dose thymoglobulin induction from 2001 onward (n = 52 patients). Ganciclovir preemptive therapy was guided by pp65 antigenemia monitoring without CMV prophylaxis. RESULTS: The study groups were homogeneous with respect to major perioperative risk factors. Comparing the two AZA subgroups no difference emerged as to percentage of pp65 antigenemia-positive, preemptively treated patients reflecting CMV disease incidence and relapses. AZA-Thymo patient showed significantly shorter time to first positive pp65-antigenemia and higher viral load (AZA-Thymo vs AZA-ATG, P = .004 and P = .009). The two subgroups did not differ with regard to incidence of rejection, superinfection, and graft coronary disease. By shifting from AZA to MMF no difference emerged as to incidence and characteristics of CMV infections, but there was a significant reduction in acute rejection and superinfection (AZA vs MMF P = .001 and P = .008). CONCLUSIONS: The distinct immunological properties of thymoglobulin versus ATG significantly altered the pattern of CMV expression. MMF with reduced-dose induction did not engender a higher CMV morbidity.

Basal lamina structural alterations in human asymmetric aneurismatic aorta.

Basal lamina (BL) is a crucial mechanical and functional component of blood vessels, constituting a sensor of extracellular microenvironment for endothelial cells and pericytes. Recently, an abnormality in the process of matrix microfibrillar component remodeling has been advocated as a mechanism involved in the development of aortic dilation. We focused our attention on BL composition and organization and studied some of the main components of the Extracellular Matrix such as Tenascin, Laminins, Fibronectin, type I, III and IV Collagens. We used surgical fragments from 27 patients, submitted to operation because of aortic root aneurysm and 5 normal aortic wall specimens from heart donors without any evidence for aneurysmal or atherosclerotic diseases of the aorta. Two samples of aortic wall were harvested from each patient, proximal to the sinotubular junction at the aortic convexity and concavity. Each specimen was processed both for immunohistochemical examination and molecular biology study. We compared the convexity of each aortic sample with the concavity of the same vessel, and both of them with the control samples. The synthesis of mRNA and the levels of each protein were assessed, respectively, by RT-PCR and Western Blot analysis. Immunohistochemistry elucidated the organization of BL, whose composition was revealed by molecular biology. All pathological samples showed a wall thinner than normal ones. Basal lamina of the aortic wall evidentiated important changes in the tridimensional arrangement of its major components which lost their regular arrangement in pathological specimens. Collagen I, Laminin alpha2 chain and Fibronectin amounts decreased in pathological samples, while type IV Collagen and Tenascin synthesis increased. Consistently with the common macroscopic observation that ascending aorta dilations tend to expand asymmetrically, with prevalent involvement of the vessel convexity and relative sparing of the concavity, Collagen type IV is more evident in the concavity and Tenascin in the convexity.

Myocardial protection with insulin cardioplegia: who can really benefit?

AIM: The aim of the study was to evaluate the effects on myocardial protection of insulin-enriched warm blood cardioplegia (IWBC) in coronary artery bypass grafting (CABG) and in subgroups of patients with associated cardiac co-morbidities. METHODS: Between May 2000 and December 2002, 268 consecutive patients underwent CABG with warm blood cardioplegia (group A) or IWBC (10 UI/L) (group B). Hospital outcome, ECG, echocardiography and biochemical markers of ischemia were compared. Differences between subgroups of patients with unstable angina (UA), ventricular hypertrophy (VH) and diabetes were assessed. RESULTS: Hospital mortality, incidence of postoperative myocardial infarction and low output syndrome, IABP requirement, postoperative atrial fibrillation, in-hospital and in-ITU stay, postoperative recovery of left ventricular function and enzyme leakage did not show differences between the 2 groups; inotropic support was lower in IWBC. Moreover, patients with UA and IWBC showed a lower troponin I (TnI) (12 h: 0.82+/-0.57 ng/mL vs 2.56+/-1.18, P < 0.0001; 24 h: 0.71+/-0.64 vs 2.16+/-1.52, P < 0.0001; 48 h: 0.69+/-1.13 vs 1.79+/-1.43, P = 0.001; 72 h: 0.44+/-0.83 vs 1.01+/-1.02, P = 0.001), lower incidence of atrial fibrillation (4.2% versus 60.6%; P < 0.0001) and intraoperative defibrillation (0% versus 27.3%; P = 0.007). Furthermore, patients with VH treated with IWBC showed lower level of TnI (12 h: 0.41+/-0.32 ng/mL vs 2.93+/-0.67, P < 0.0001; 24 h: 0.37+/-0.45 vs 2.40+/-1.28, P < 0.0001; 48 h: 0.22+/-0.18 vs 1.95+/-1.33, P < 0.0001; 72 h: 0.12+/-0.12 vs 1.31+/-1.56, P < 0.0001), lower atrial fibrillation (6.5% vs 48%, P < 0.0001) and ventricular defibrillation (0% vs 20%, P = 0.011). CONCLUSIONS: Insulin addiction to blood cardioplegia does not show any benefit in the global population and in diabetics; nevertheless, better myocardial protection can be demonstrated in patients with unstable angina and left ventricular hypertrophy.

The heart in uremia: role of hypertension, hypotension, and sleep apnea.

Cardiovascular disease is the leading cause of morbidity and mortality in end-stage renal disease. Causes include those usually found in the general population, those related to the uremic status, and those related to dialytic treatment. Hypertension, hypotension, anemia, hypoalbuminemia, malnutrition, dyslipidemia, reactive C protein, calcium-phosphate product, dialysis modalities, and hyperhomocysteinemia are discussed extensively. Special emphasis is put on hyperparathyroidism as a traditional toxin. The emergent role of sleep apnea has been confirmed in animal models as well as in humans studied using polysomnography. There are difficulties in diagnosing coronary disease, because angiography is not risk-free, is expensive, and should be reserved for patients having symptoms of heart failure and/or patients having diabetes mellitus, and/or patients entering a transplantation list. This allows patients with coronary disease to undergo coronary artery bypass (preferably) or percutaneous transluminal angioplasty. Patients for whom surgery is not appropriate should be treated using more traditional medical procedures.

Hemodialitic treatment of cardiac failure.

The various options for treatment of diuretic-resistant edema in heart failure and report on their experience with on line bicarbonate daily hemofiltration (135 min) in 16 patients with congestive heart failure IV class NYHA is discussed. The outcome was excellent. Only 6 patients died. Survival averaged 25 weeks in 4 patients. A total of 6 patients are still alive on dialysis after 18 to 52 weeks.

Bioelectrical impedance analysis in heart transplantation: early and late changes.

The objectives of this study were to perform bioelectrical impedance analysis before and after heart transplantation with comparison to healthy subjects. Eight patients (7 men, 1 woman) before (day 0) and after transplantation (day 3, 7, 12, 15, and 180) and 24 healthy controls, matched for sex, age, and body mass were studied. Data collection included bioelectrical impedance analysis (resistance, reactance, and estimates of body water), clinical, and laboratory measurements. Compared with controls, patients had at baseline significantly higher reactance, not significantly different resistance, body weight, total body water, and intra- to extracellular water ratio. After surgery, for reactance, there was an acute decrease followed by a slow, progressive increase up to normal level by day 15. Resistance and body weight did not significantly change; the intra- to extracellular water ratio significantly decreased with stable total body water. Changes in reactance are the main effects induced on bioelectrical impedance by heart transplantation. Acutely, there is a large decrease which likely reflects changes both in water distribution and in cell membrane function. The late changes more likely reflect the shift of body water from the extra- to the intracellular space with stable total body water.

Desmin-free cardiomyocytes and myocardial dysfunction in end stage heart failure.

Our aim was to evaluate the desmin content in the myocardial tissue of patients with end-stage heart failure of ischaemic origin and to assess its role on cardiac function. We studied 18 explanted hearts from patients transplanted for end-stage heart failure due to ischaemic cardiomyopathy (ICM). Control myocardial tissue was obtained from the cardiac biopsies of six women with breast cancer taken prior to commencing chemotherapy with anthracyclines, four male donors for heart transplantation and two autoptic hearts from patients who died due to non-cardiac events. Myocardial tissue, obtained from the left ventricle (remote zone from infarcted area), was analyzed by light and confocal immunochemistry (desmin) microscopy. The desmin content of myocardial tissue was obtained by real-time PCR. Cardiac function was evaluated by echocardiographic and right heart catheterization data, obtained before heart transplantation. Confocal microscopy evaluation showed a significant decrease in the number of desmin-positive myocytes (P<0.01) in ICM hearts compared to controls. At real-time PCR evaluation, there was a reduction (P<0.01) in desmin content in the ICM patients compared to controls. A negative correlation was found between desmin-free cardiomyocytes and ejection fraction (EF) (r=-0.834; P<0.02) on echocardiogram. A negative relationship (r=-0.688) was also found between desmin-negative myocytes and capillary wedge pressure. In conclusion, the myocardial tissue of patients with end-stage heart failure of ischaemic origin, shows a decreased number in desmin-positive myocytes at immunochemistry evaluation compared to normal individuals. This deficiency in cytoskeletal intermediate filament content is associated with reduced cardiac function.

Salt: a sacred substance.

Salt is the last relic of the ocean where life was born. Its presence has influenced the whole gamut of history and its name is linked to hundred of geographical locations. Its importance for nutrition is supported by the discovery of Aeneolithic salt cellars. Salt cellars and pyramids of salt have been included in paintings and other works of art. In Japan where salt was and still is obtained from the sea, a salt culture has developed that can be traced in the rituals of everyday life, including meal preparation, sports, and Shinto ceremonies.
