RESUMO

BACKGROUND: Muscle function and its correlation with body composition and weight loss have not been studied deeply in pancreas and gastrointestinal cancers. This research aims to determine the skeletal muscle function and its relationship with body compartments, significant weight loss, and performance status (ECOG) 0-2 in a population with advanced digestive cancers. METHODS: A cross-sectional study was designed to determine the relationship between muscular function, weight loss, and body composition. Patients with advanced digestive adenocarcinomas were evaluated. Muscle strength was examined by hand grip technique and body composition by bioimpedance analysis. Values of hemoglobin and albumin were measured in plasma. RESULTS: A sample of 81 patients was included. They had adenocarcinoma of stomach (n = 9), pancreas (n = 28), or colorectum (n = 44). With regard to skeletal muscle function, sub-maximal strength increased when percentage of weight loss decreased (p = 0.002) or when any of the following variables increased: skeletal muscle (p < 0.001), waist-hip ratio (p < 0.001), body surface area (p < 0.001), and body mass index (p = 0.001). According to multivariate analysis of these variables, only percentage of weight loss and skeletal muscle remained statistically significant. Endurance had no correlation with any of the variables. Higher weight loss was found in tumors of the upper tract (stomach and pancreas) in comparison with those of the lower tract (colorectal) (p = 0.005). CONCLUSIONS: In advanced digestive cancer, sub-maximal strength correlated inversely with weight loss and directly with skeletal muscle such as in lung and head and neck cancers. On the other hand, endurance had no correlation with any of the variables considered.

RESUMO

BACKGROUND AND AIMS: Reduction of left ventricular mass index (LVMi) during antihypertensive treatment is less likely to occur in obese subjects. The aim of the study was to assess whether weight loss influences reduction of LVMi in treated, obese, hypertensive patients. METHODS AND RESULTS: From the Campania Salute Network registry, we identified 1546 obese hypertensive patients (50 ± 9 years, 43% women) with more than 12 months follow-up. Echocardiographic reduction of LVMi was considered as achievement of normal values (<47 g/m2.7 in women or <50 g/m2.7 in men) or a reduction of ≥10% during follow-up. Weight loss was considered as ≥5% reduction in body weight, and occurred in 403 patients (26%) during a median follow-up of 50 months (IQrange:31-93). Median weight loss was 8.6% (IQrange:6.5-12). Patients with weight loss had higher baseline body mass index (p < 0.05), while there was no difference in age, sex, duration of hypertension, prevalence of diabetes, metabolic syndrome and average blood pressure during follow-up. During follow-up, 152 patients (9.8%) exhibited reduction of LVMi. Reduction of LVMi was more frequent (12.9% vs 9.1%, p < 0.030) in patients losing weight than in those who did not. In logistic regression analysis, weight loss was associated with reduction of left ventricular mass index (OR 1.51 [95%CI 1.02-2.23], p = 0.039), independent of significant associations with younger age, lower average systolic blood pressure during follow-up, longer follow-up time and higher LVMi at baseline. CONCLUSION: In treated obese hypertensive patients, weight loss during follow-up promotes significant reduction of LVMi, independent of baseline characteristics and blood pressure control.

RESUMO

Minimally invasive Heller myotomy is considered the gold standard surgical approach for symptomatic achalasia because it is a safe and effective procedure. Over the last years, several studies comparing the laparoscopic and robotic approach for Heller myotomy have been published. Although the robotic approach appears to have some advantages over standard laparoscopy, data on this topic are still controversial and no definite conclusions have been drawn. This metanalysis has been designed to systematically evaluate and compare the effectiveness and safety of the robot-assisted Heller myotomy as compared to the standard laparoscopic approach. According to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, a systematic search on both laparoscopic and robotic Heller myotomy was performed in all the major electronic databases (PubMed, Web of Science, Scopus, EMBASE), using the following search string: (achalasia OR Dor) AND robotic. Six articles were included in the final analysis. A metaregression analysis was performed to assess the possible effects of demographic variables (age, gender, body mass indes (BMI)) and previous abdominal surgery or endoscopic intervention on the analyzed outcomes. No statistical difference was observed in operative times (mean difference (MD) = 20.79, P = 0.19, 95% confidence interval (CI) -10.05,51,62), estimated blood loss (MD = -17.10, P = 0.13, 95% CI -40.48,5.08), conversion rate to open surgery (risk difference (RD) = -0.01, P = 0.33, 95% CI -0.05,0.02), length of hospital stay (MD = -0.73, P = 0.15, 95% CI -1.71,0.25) and long-term recurrence (odds ratio (OR) = 0.59, P = 0.45, 95% CI 0.15,2.33). On the contrary, the robotic approach was found to be associated with a significantly significant lower rate of intraoperative esophageal perforations (OR = 0.13, P < 0.001, 95% CI 0.04, 0.45). Our results suggest that the robotic approach is safer than the laparoscopic Heller myotomy, encouraging the use of robot-assisted surgery. However, our analysis is limited because of the exiguous number of comparative studies and because most of the included studies were statistically underpowered, given the small sample size. Moreover, a high degree of heterogeneity was observed in most of published studies. Taking in consideration the additional costs of robot-assisted procedures, larger Randomized Controlled Trials (RCTs) are advocated to confirm the safety and effectiveness of the robotic approach, and its advantages over standard laparoscopic surgery. In conclusion, well-designed prospective trials and RCTs with homogeneous parameters are needed to draw definitive conclusions about the best surgical approach to pursue in treating symptomatic achalasia.

RESUMO

BACKGROUND: Different markers have been used preoperatively to mark colonic lesions, especially India ink. In recent years, another kind of marker has been developed: sterile carbon particle suspension (SCPS). No comparison between these two markers has yet been made. The aim of the present study was to compare the pyrogenic, inflammatory and intraperitoneal effect of these two markers. METHODS: From September 2015 to December 2018, adult patients who were candidates for elective laparoscopic colon resection were randomized to the SCPS or conventional India ink injection group using computer-based randomization. The primary endpoint of the study was the presence of intraoperative adhesions related to the endoscopic tattoo. Secondary endpoints were differences in white blood cell, C-reactive protein, and fibrinogen levels as well as, abdominal pain and body temperature at baseline (before endoscopic tattooing) and 6 and 24 h after colonoscopy. Finally, the visibility of the tattoo during the minimally invasive intervention was assessed. RESULTS: Ninety-four patients were included in the study, 47 for each arm. There were 45/94 females (47.9%) and 49/94 males (52.1%), with a median age of 67.85 ± 9.22 years. No differences were found between groups in WBC, fibrinogen levels, body temperature or VAS scores, but we documented significantly higher CRP values at 6 and 24 h after endoscopic tattooing with India ink injection. There were significantly fewer adhesions in the SCPS Endoscopic Marker group. All the endoscopic tattoos were clearly visible. CONCLUSIONS: SCPS is an effective method for tattooing colonic lesions and has a better safety profile than traditional India ink in terms of post-procedure inflammatory response and intraoperative bowel adhesions.

RESUMO

BACKGROUND AND AIMS: Circulating uric acid (UA) is positively associated with body mass index (BMI), blood glucose, blood pressure (BP), markers of inflammation, and altered lipid profile. UA has also anti-oxidative properties which might be beneficial for cardiovascular (CV) system. It is still debated whether or not UA is independently associated with increased CV morbidity and/or mortality. METHODS AND RESULTS: We studied prognostic impact of UA in 8833 hypertensive adults (mean age 53 ± 12 yrs, 3857 women) from the Campania Salute Network, without prevalent CV disease and more than stage 3 CKD. We calculated standardized UA Z-score, adjusted for age, sex, glomerular filtration rate, and BMI. Low and high UA and UA Z-score quartiles were compared to the 2 middle quartiles assumed to be "normal". Prevalence of obesity and diabetes was higher in low and high than in normal UA Z-score group (all p < 0.001). Systolic BP, left ventricular mass, carotid intima thickness were significantly higher and ejection fraction was reduced in the presence of high UA Z-score (all p < 0.001). Over 33-months average follow-up, incident major CV end-points (MACE) were not significantly different among low, normal and high UA or UA Z-score. In the latter analysis, however, incident MACE tended to be more frequent in the low than the high UA Z-score. Despite the results of multivariable analyses, the effect of less aggressive therapy in low UA Z-score cannot be excluded with certainty. CONCLUSION: In treated hypertensive patients, high levels of UA normalized for major biological determinants do not independently predict CV outcome. CLINICALTRIALS. GOV IDENTIFIER: NCT02211365.

RESUMO

BACKGROUND AND AIMS: Hypertension (HTH) is a frequent complication in pediatric obesity. To simplify the screening of HTH in overweight/obese (Ow/Ob) youth, we compared the performance of a new index (High Blood Pressure index, HBPi) with respect to the standard criteria of the IV Report [systolic BP (SBP) and/or diastolic BP (DBP) ≥95th percentile for age, gender and height]. We also compared the performance of HBPi with other simplified indices such as the BP/height ratio and the absolute height-specific BP thresholds. Ten pediatrics' outpatient centers participating in the "CARdiometabolic risk factors in ITALY study" provided medical records of 4225 Ow/Ob children and adolescents (age 6-16 years). METHODS AND RESULTS: Centers were divided into two groups: training set (TS) (n = 2204 participants) and validation set (VS) (n = 2021 participants). The simplified HBPi (mmHg) was: (SBP/2 + DBP/10) - age + (1 × female gender). In the TS, a HBPi value ≥57 mmHg in both children and adolescents had high sensitivity (0.89), specificity (0.97), positive (0.89) and negative (0.97) predictive values in classifying youth at high risk of HTN compared with the IV Report. In the VS, the HBPi showed a better performance than high levels of BP/height ratio and height-specific BP thresholds in classifying individuals at risk of HTN: area under curves 0.95 (0.93-0.96), 0.80 (0.78-0.82), 0.76 (0.74-0.79), respectively; specificities 0.95 (0.94-0.96), 0.69 (0.67-0.72), 0.60 (0.57-0.62), respectively. CONCLUSIONS: HBPi, combining SBP and DBP, gender and age, may help pediatricians to implement HTN screening in Ow/Ob youth.

RESUMO

6-Sulfamoyl-saccharin was investigated as an inhibitor of 11 α-carbonic anhydrase (CA, EC 4.2.1.1) isoforms of human (h) origin, hCA I-XIV, and X-ray crystallographic data were obtained for its adduct with hCA II, the physiologically dominant isoform. This compound possesses two potential zinc-binding groups, the primary sulfamoyl one and the secondary, acylatedsulfonamide. Saccharin itself binds to the Zn(II) ion from the CA active site coordinating with this last group, in deprotonated (SO2N(-)CO) form. Here we explain why 6-sulfamoyl-saccharin, unlike saccharin, binds to the metal ion from the hCA II active site by its primary sulfonamide moiety and not the secondary one as saccharin itself. Our study is useful for shedding new light to the structure-based drug design of isoform-selective CA inhibitors of the sulfonamide type.

RESUMO

BACKGROUND AND AIM: Association of coronary and renal disease has been frequently found in epidemiological studies. Whether ECG-graphic presentation of myocardial infarction [S-T Elevated MI (STEMI) or Non S-T Elevated MI (NSTEMI)] is related to the degree of renal dysfunction is still unclear. METHODS AND RESULTS: We examined 146 patients with acute myocardial infarction, consecutively entering the Coronary Care Unit of our ward. At entry, patients underwent clinical, ECG-graphic and echocardiographic examination, and blood samples were withdrawn for cardiac markers and general biochemistry. GFR was calculated using the CKD-EPI equation. STEMI was found in 71 cases and NSTEMI in 75 cases. Renal function was normal in 61 patients (stage 1), mildly impaired (<90 mL/min/1.73 m(2) and ≥ 60 mL/min/1.73 m(2)) in 60 (stage 2) and moderately to severely impaired (GFR <60 mL/min/1.73 m(2)) in 25 cases (stages 3-4). Patients were, thereafter, clustered into two groups (stages 1-2 and stages 3-4). Compared to stage 1-2 subjects, stages 3-4 patients were older, were more likely to be diabetic and had more frequently previous cardiovascular diseases. The probability of presentation of NSTEMI for stage 3-4 patients was 4-fold greater than for stage 1-2 patients (p = 0.02). CONCLUSIONS: These data support the evidence that 1) NSTEMI is associated with more severe kidney dysfunction, likely due to more severe and/or longer lasting exposition to risk factors; 2) cardiac and renal impairment are strongly associated.

RESUMO

Antiretroviral therapy allows a restoration of immune cell homeostasis associated with a normal immune competence. Our goal was to analyze the modulation of polyfunctional HIV-specific CD8+ T-cell responses during antiretroviral therapy. HIV-infected individuals were divided into four groups according to CD4+ cell count and viral load at the moment of recruitment. Whole blood was stimulated with a pool of CD8-specific HIV-antigens to assess cytokine/chemokine production and cytotoxicity activity by using flow cytometry. The groups show different modulation in HIV-specific CD8+ T-cell responses. In particular, immunological failure showed different distributions of polyfunctional HIVspecific CD8+ responses, mainly due to an increase of cells producing CD107alpha/IFNgamma/IL-2/MIP-1beta. Our results indicate that this particular 4+ functional subset is a possible correlate of immunological failure. Considering the complexity of interactions among HAART, immune system and HIV, work is in progress to find correlates of therapy efficacy.

RESUMO

BACKGROUND AND AIM: Sarcopenia is a condition mainly due to loss of fat-free mass (FFM) in elderly individuals. RFFMD, however, is also frequent in obese subjects due to abnormal body composition. Objective of this study was to evaluate the impact of relative fat-free mass deficiency (RFFMD) on cardiometabolic (CM) risk in obese normoglycemic individuals. METHODS AND RESULTS: Overweight/obese American Indians from the Strong Heart Study population, without diabetes and with FBG ≤ 110 mg/dL and with GFR >60 mg/mL/1.73 m(2) were selected for this analysis (n = 742). RFFMD was defined on the basis of a multivariable equation previously reported. Fasting glucose and 2 h-OGTT were measured together with urine albumin/creatinine excretion, laboratory and anthropometric parameters. In addition to lower FFM and greater adipose mass, participants with RFFMD had higher body mass index, waist circumference, C-reactive protein, fibrinogen, insulin resistance and urinary albumin/creatinine than participants with normal FFM (all p < 0.001); they also had a greater prevalence of hypertension, impaired glucose tolerance (IGT) or OGTT-diabetes than participants with normal FFM (all p < 0.003) and a near 2-fold greater probability of significant proteinuria (p < 0.01). RFFMD was more frequent in women than in men: significant sex-RFFMD interactions were found for BMI and waist circumference (both p < 0.0001). CONCLUSIONS: RFFMD in overweight/obese normoglycemic individuals is associated with greater probability of hypertension, abnormalities of glucose tolerance and proteinuria. Assessment of RFFRMD might, therefore, help stratifying cardiometabolic risk among normoglycemic individuals with overweight/obesity.

RESUMO

AIM: To evaluate whether uric acid (UA) predicts 4-yr incidence of metabolic syndrome (MetS) in non-diabetic participants of the Strong Heart Study (SHS) cohort. METHODS AND RESULTS: In this population-based prospective study we analyzed 1499 American Indians (890 women), without diabetes or MetS, controlled during the 4th SHS exam and re-examined 4 years later during the 5th SHS exam. Participants were divided into sex-specific tertiles of UA and the first two tertiles (group N) were compared with the third tertile (group H). Body mass index (BMI = 28.3 ± 7 vs. 31.1 ± 7 kg/m(2)), fat-free mass (FFM = 52.0 ± 14 vs. 54.9 ± 11 kg), waist-to-hip ratio, HOMA-IR (3.66 vs. 4.26), BP and indices of inflammation were significantly higher in group H than in group N (all p < 0.001). Incident MetS at the time of the 5th exam was more frequent in group H than group N (35 vs. 28%, OR 1.44 (95% CI = 1.10-1.91; p < 0.01). This association was still significant (OR = 1.13, p = 0.04) independently of family relatedness, sex, history of hypertension, HOMA-IR, central adiposity and renal function, but disappeared when fat-free mass was included in the model. CONCLUSIONS: In the SHS, UA levels are associated to parameters of insulin resistance and to indices of inflammation. UA levels, however, do not predict incident MetS independently of the initial obesity-related increased FFM.

RESUMO

BACKGROUND: Skeletal Stem Cells (SSCs) are required for skeletal development, homeostasis, and repair. The perspective of their wide application in regenerative medicine approaches has supported research in this field, even though so far results in the clinic have not reached expectations, possibly due also to partial knowledge of intrinsic, potentially actionable SSC regulatory factors. Among them, the pleiotropic cytokine RANKL, with essential roles also in bone biology, is a candidate deserving deep investigation. METHODS: To dissect the role of the RANKL cytokine in SSC biology, we performed ex vivo characterization of SSCs and downstream progenitors (SSPCs) in mice lacking Rankl (Rankl-/-) by means of cytofluorimetric sorting and analysis of SSC populations from different skeletal compartments, gene expression analysis, and in vitro osteogenic differentiation. In addition, we assessed the effect of the pharmacological treatment with the anti-RANKL blocking antibody Denosumab (approved for therapy in patients with pathological bone loss) on the osteogenic potential of bone marrow-derived stromal cells from human healthy subjects (hBMSCs). RESULTS: We found that, regardless of the ossification type of bone, osteochondral SSCs had a higher frequency and impaired differentiation along the osteochondrogenic lineage in Rankl-/- mice as compared to wild-type. Rankl-/- mice also had increased frequency of committed osteochondrogenic and adipogenic progenitor cells deriving from perivascular SSCs. These changes were not due to the peculiar bone phenotype of increased density caused by lack of osteoclast resorption (defined osteopetrosis); indeed, they were not found in another osteopetrotic mouse model, i.e., the oc/oc mouse, and were therefore not due to osteopetrosis per se. In addition, Rankl-/- SSCs and primary osteoblasts showed reduced mineralization capacity. Of note, hBMSCs treated in vitro with Denosumab had reduced osteogenic capacity compared to control cultures. CONCLUSIONS: We provide for the first time the characterization of SSPCs from mouse models of severe recessive osteopetrosis. We demonstrate that Rankl genetic deficiency in murine SSCs and functional blockade in hBMSCs reduce their osteogenic potential. Therefore, we propose that RANKL is an important regulatory factor of SSC features with translational relevance.

RESUMO

Obesity is characterized by the disproportionate growth of the components of body size, including adipose tissue and lean body mass. Left ventricular (LV) hypertrophy often develops, due to the coexistence of hemodynamic (cardiac workload) and non-hemodynamic components (including body composition and activity of visceral fat). While the hypertrophy of cardiomyocytes is produced by the hemodynamic load, through sarcomeric replication, there is a parallel growth of non-muscular myocardial components, including interstitial fat infiltration and accumulation of triglycerides in the contractile elements, which are thought to influence LV geometric pattern. Thus, pure intervention on hemodynamic load is unlikely to result in effective reduction of LV hypertrophy in obese.

RESUMO

BACKGROUND AND AIMS: The ESC/ESH guidelines for arterial hypertension recommend using statins for patients with high cardiovascular (CV) risk for both secondary and primary prevention. A recent meta-analysis, combining previous studies on statins, concluded that they are associated with a 9% increased risk of incident type 2 diabetes mellitus (DM). There is no information on whether statins increase incidence of DM in primary prevention. METHOD AND RESULTS: We evaluated risk of incident DM in relation to statin prescription in 4750 hypertensive, non-diabetic outpatients (age 58.57 ± 9.0 yrs, 42.3% women), from the CampaniaSalute Network, without chronic kidney disease more than grade 3, free of prevalent CV disease and with at least 12 months of follow-up. DM was defined according to ADA criteria. At the end of follow-up period (55.78 ± 42.5 months), 676 patients (14%) were on statins. These patients were older (62.54 ± 7.3 vs 57.91 ± 9.1 yrs; p < 0.0001), more often female (49% vs 41.2%; p = 0.0001), with higher initial total cholesterol (217.93 ± 44.3 vs 205.29 ± 36.6 mg/dl), non-HDL cholesterol (167.16 ± 44.5 vs 155.18 ± 36.7 mg/dl) and triglycerides (150.69 ± 85.2 vs 130.98 ± 72.0 mg/dl; all p < 0.0001) than patients no taking statins, without other differences in clinical and laboratory characteristics. At the end of follow-up, prevalence of DM was 18.1% among patients on statins and 7.2% among those without lipid-lowering therapy (p < 0.0001). However, incident DM was 10.2% in patients on statins and 8.7% in those free of statin therapy (NS). CONCLUSION: In real-life outpatient environment, statin prescription for primary prevention is not associated with increased risk of incident DM.

RESUMO

BACKGROUND AND AIMS: Metabolic syndrome (MetS) is a complex condition characterized by different phenotypes, according to the combinations of risk factors and is associated with cardiovascular abnormalities. Whether control of MetS components by treatment produces improvement in the associated cardiovascular abnormalities is unknown. We investigated whether partial control of components of MetS was associated with less echocardiographic abnormalities than the complete presentation of MetS based on measured components. METHODS AND RESULTS: We evaluated markers of echocardiographic preclinical cardiovascular disease in MetS (ATP III) defined by measured components or by history of treatment, in 1421 African-American and 1195 Caucasian non-diabetic HyperGEN participants, without prevalent cardiovascular disease or serum creatinine >2 mg/dL. Of 2616 subjects, 512 subjects had MetS by measured components and 328 by history. Hypertension was found in 16% of participants without MetS, 6% of those with MetS by history and 42% of those with MetS by measured components. Obesity and central fat distribution had similar prevalence in both MetS groups (both p < 0.0001 vs. No-MetS). Blood pressure was similar in MetS by history and No-MetS, and lower than in MetS by measured components (p < 0.0001). LV mass and midwall shortening, left atrial (LA) dimension and LA systolic force were similarly abnormal in both MetS groups (all p < 0.0001 vs. No-MetS) without difference between them. CONCLUSIONS: There is a little impact of control by treatment of single components of MetS (namely hypertension) on echocardiographic abnormalities. Lower blood pressure in participants with MetS by history was not associated with substantially reduced alterations in cardiac geometry and function.

RESUMO

BACKGROUND AND AIMS: Increased body mass index (BMI) has been associated with increased cardiovascular morbidity and mortality in hypertension. Less is known about the impact of BMI on improvement in left ventricular (LV) structure and function during antihypertensive treatment. METHODS AND RESULTS: Annual BMI, echocardiograms and cardiovascular events were recorded in 875 hypertensive patients with LV hypertrophy during 4.8 years randomized treatment in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) echocardiography substudy. Patients were grouped by baseline BMI into normal (n = 282), overweight (n = 405), obese (n = 150) and severely obese groups (n = 38) (BMI ≤24.9, 25.0-29.9, 30.0-34.9, and ≥35.0 kg/m(2), respectively). At study end, residual LV hypertrophy was present in 54% of obese and 79% of severely obese patients compared to 31% of normal weight patients (both p < 0.01). In regression analyses, adjusting for initial LV mass/height(2.7), higher BMI predicted less LV hypertrophy reduction and more reduction in LV ejection fraction (both p < 0.05), independent of blood pressure reduction, diabetes and in-study weight change. During follow-up, 91 patients suffered cardiovascular death, myocardial infarction or stroke. In Cox regression analysis 1 kg/m(2) higher baseline BMI predicted a 5% higher rate of cardiovascular events and 10% higher cardiovascular mortality over 4.8 years (both p < 0.05). CONCLUSIONS: In hypertensive patients in the LIFE study, increased BMI was associated with less reduction of LV hypertrophy and less improvement in LV systolic function which may contribute to the observed higher cardiovascular event rate of treated hypertensive patients.

RESUMO

BACKGROUND AND AIMS: Diabetes remains a predictor of incident heart failure (HF), independent of intercurrent myocardial infarction (MI) and concomitant risk factors. Initial cardiovascular (CV) characteristics, associated with incident heart failure (HF) might explain the association of diabetes with incident HF. METHODS AND RESULTS: Participants to the 2nd Strong Heart Study exam, without prevalent HF or coronary heart disease, or glomerular filtration rate <30 mL/min/1.73 m(2), were analyzed (n = 2757, 1777 women, 1278 diabetic). Cox regression of incident HF (follow-up 8.91 ± 2.76 years) included incident MI censored as a competing risk event. Acute MI occurred in 96 diabetic (7%) and 84 non-diabetic participants (6%, p = ns). HF occurred in 156 diabetic (12%) and in 68 non-diabetic participants (5%; OR = 2.89, p < 0.001). After accounting for competing MI and controlling for age, gender, BMI, systolic blood pressure, smoking habit, plasma cholesterol, antihypertensive treatment, heart rate, fibrinogen and C-reactive protein, incident HF was predicted by greater LV mass index, larger left atrium, lower systolic function, greater left atrial systolic force and urinary albumin/creatinine excretion. Risk of HF was reduced with more rapid LV relaxation and anti-hypertensive therapy. Diabetes increases hazard of HF by 66% (0.02 < p < 0.001). The effect of diabetes could be explained by the level of HbA1c. CONCLUSIONS: Incident HF occurs more frequently in diabetes, independent of intercurrent MI, abnormal LV geometry, subclinical systolic dysfunction and indicators of less rapid LV relaxation, and is influenced by poor metabolic control. Identification of CV phenotype at high-risk for HF in diabetes should be advised.

RESUMO

BACKGROUND AND AIM: We analyzed the effect of the mineralocorticoid receptor antagonist canrenone on LV mechanics in patients with or without metabolic syndrome (MetS) and compensated (Class II NYHA) heart failure (HF) with reduced ejection fraction (EF≤45%) on optimal therapy (including ACE-i or ARB, and ß-blockers). METHODS AND RESULTS: From a randomized, double-blind placebo-controlled trial (AREA-in-CHF), patients with (73 on canrenone [Can] and 77 on placebo [Pla]), based on modified ATPIII definition (BMI≥30kg/m(2) instead of waist girth) or without MetS (146 by arm). In addition to traditional echocardiographic parameters, we also evaluated myocardial mechano-energetic efficiency (MME) based on a previously reported method. At baseline, Can and Pla did not differ in age, BMI, blood pressure (BP), metabolic profile, BNP, and PIIINP. Compared with MetS-Pla, and controlling for age, sex and diabetes, at the final control MetS-Can exhibited increased MME, preserved E/A ratio, and decreased atrial dimensions (0.04

RESUMO

Demographic changes in the Western world linked to the increase in the elderly population, life expectancy and above all cancer patients and chronically ill patients, often entrusted to home care or in healthcare residences, highlight an exponential increase in requests for diagnostic tests at home. Conventional radiographic examinations, such as thoracic, musculoskeletal and abdominal images are the most requested and are important first level diagnostic tests. To date and, in particular, in times of COVID-19 emergency, these patients need to be transferred to the hospital to perform radiological examinations which involve an increase in costs for the health system and an increased risk for the health of these patients, already often debilitated and immunocompromised. This article discussed the benefits of taking conventional chest x-rays directly at the patient's home.
