Sex differences in transthyretin cardiac amyloidosis.

Transthyretin cardiac amyloidosis (ATTR-CA) is a progressive disease characterized by the deposition of abnormal transthyretin protein fibrils in the heart, leading to cardiac dysfunction. Recent evidence suggests that sex differences may play a significant role in various steps of ATTR-CA, including clinical presentation, diagnostic challenges, disease progression, and treatment outcomes. ATTR-CA predominantly affects men, whereas women are older at presentation. Women generally present with a history of heart failure with preserved ejection fraction and/or carpal tunnel syndrome. When indexed, left ventricular (LV) wall thickness is equal, or even increased, than men. Women also have smaller LV cavities, more preserved ejection fractions, and apparently a slightly worse right ventricular and diastolic function. Given the under-representation on women in clinical trials, no data regarding sex influence on the treatment response are currently available. Finally, it seems there are no differences in overall prognosis, even if premenopausal women may have a certain level of myocardial protection. Genetic variations, environmental factors, and hormonal changes are considered as potential contributors to observed disparities. Understanding sex differences in ATTR-CA is vital for accurate diagnosis and management. By considering these differences, clinicians can improve diagnostic accuracy, tailor treatments, and optimize outcomes for both sexes with ATTR-CA.

Gender Differences and Cardiometabolic Risk: The Importance of the Risk Factors.

Metabolic syndrome (Mets) is a clinical condition characterized by a cluster of major risk factors for cardiovascular disease (CVD) and type 2 diabetes: proatherogenic dyslipidemia, elevated blood pressure, dysglycemia, and abdominal obesity. Each risk factor has an independent effect, but, when aggregated, they become synergistic, doubling the risk of developing cardiovascular diseases and causing a 1.5-fold increase in all-cause mortality. We will highlight gender differences in the epidemiology, etiology, pathophysiology, and clinical expression of the aforementioned Mets components. Moreover, we will discuss gender differences in new biochemical markers of metabolic syndrome and cardiovascular risk.

Long-term effects of a combination of isoflavones, agnus castus and magnolia extracts on climacteric symptoms and cardiometabolic risk profile in postmenopausal women.

OBJECTIVE: To evaluate the long-term effects of a combination of isoflavones, agnus castus and magnolia extracts (combined isoflavone compound [CIC]) on climacteric symptoms and cardiometabolic risk in symptomatic postmenopausal women. METHODS: This interventional, prospective study evaluated climacteric symptoms, mood and sleep disorders using the 21-item Greene Climacteric Scale (GCS) and 7-item Insomnia Severity Index (ISI) questionnaires; and cardiovascular, metabolic and thrombotic risk markers at baseline (T0) and after 12 months of CIC treatment (T1). RESULTS: In healthy postmenopausal women (N = 71), 12-month CIC treatment significantly reduced patient-reported vasomotor symptoms (100% vs. 17%), mood disorders (67% vs. 25%) and sleep disorders (89% vs. 19%%) (all p < .001) compared with baseline; and significantly improved GCS psychological, somatic, and vasomotor domain scores and ISI sleep disturbance scores (all p < .05). CIC significantly reduced systolic (p = .022) and diastolic blood pressure (p < .001), and heart rate (p < .001); glucose concentrations (p = .018), HOMA index (p = .013), and ALT (p = .035), homocysteine (p = .005) and NT-proBNP (p = .003) levels. CONCLUSIONS: Long-term CIC therapy improved vasomotor symptoms, mood disorders, sleep disorders, hemodynamic measurements and cardiometabolic risk markers in healthy postmenopausal women.

Gut Microbiota and Sex Hormones: Crosstalking Players in Cardiometabolic and Cardiovascular Disease.

The available evidence indicates a close connection between gut microbiota (GM) disturbance and increased risk of cardiometabolic (CM) disorders and cardiovascular (CV) disease. One major objective of this narrative review is to discuss the key contribution of dietary regimen in determining the GM biodiversity and the implications of GM dysbiosis for the overall health of the CV system. In particular, emerging molecular pathways are presented, linking microbiota-derived signals to the local activation of the immune system as the driver of a systemic proinflammatory state and permissive condition for the onset and progression of CM and CV disease. We further outline how the cross-talk between sex hormones and GM impacts disease susceptibility, thereby offering a mechanistic insight into sexual dimorphism observed in CVD. A better understanding of these relationships could help unravel novel disease targets and pave the way to the development of innovative, low-risk therapeutic strategies based on diet interventions, GM manipulation, and sex hormone analogues.

The Gynogram: A Multicentric Validation of a New Psychometric Tool to Assess Coital Pain Associated With VVA and Its Impact on Sexual Quality of Life in Menopausal Women.

BACKGROUND: Vulvo-Vaginal Atrophy (VVA) affects about fifty percent of postmenopausal women, contributing more vulnerable sexual and psycho-relational equilibrium. To date, no psychometric instruments have been designed to assess the impact of coital pain associated with VVA on sexual quality of life. AIM: To validate a new psychometric tool, the Gynogram, able to investigate coital pain and to quantify its impact on sexual well-being in menopause. METHODS: 214 sexually active postmenopausal women were enrolled in the study during clinical consultations in gynecological outpatient clinics in Italy. After gynecological examination and evaluation of the presence of VVA, the study sample was divided in a clinical group (103 women with certified diagnosis of VVA) and in a control group (111 women without certified diagnosis of VVA) according to the Vaginal Health Index (VHI) cut-off. Factor, Reliability and Receiving Operating Characteristics (ROC) analysis were performed in order to validate our newly created Gynogram. OUTCOMES: A structured questionnaire, named Gynogram, to assess coital pain and its impact, and the Female Sexual Function Index (FSFI). RESULTS: The factor analysis performed on the original form (80 items) reduced the Gynogram to 24 items. Reliability analysis conducted with Cronbach's Alpha coefficients showed high values in all the components (ranging from .813 to .972), both in the long and in the short form. The sensitivity analysis demonstrated that the Gynogram, with a cut-off ≤93, is able to recognize a clinically significant coital pain. With respect to the FSFI, statistically significant differences were found for all the domains. In addition, statistically significant differences were found for all the twelve factors of the Gynogram, showing that VVA profoundly affects the sexual quality of life of women in post-menopause. CLINICAL TRANSLATION: The utility of this tool consists in the possibility to improve prognosis, compliance/adherence and treatment outcomes. STRENGTHS AND LIMITATIONS: The Gynogram is able to evaluate and to quantify the impact of coital pain associated with VVA. Moreover, it can also recognize the areas of biopsychosocial functioning being more affected by this clinical condition. The main limit of the study is the impossibility to evaluate both mental health and partner's general and sexual health. CONCLUSIONS: The Gynogram is a new and validated psychometric tool able to detect the impact of symptomatic VVA on sexual quality of life among post-menopausal women, with a specific focus on the different areas of sexual functioning.

Quarantine during COVID-19 outbreak: Changes in diet and physical activity increase the risk of cardiovascular disease.

AIMS: CoV-19/SARS-CoV-2 is a highly pathogenic virus that is causing a global pandemic with a high number of deaths and infected people. To contain the diffusion of infection, several governments have enforced restrictions on outdoor activities or even collective quarantine on the population. The present commentary briefly analyzes the effects of quarantine on lifestyle, including nutrition and physical activity and the impact of new technologies in dealing with this situation. DATA SYNTHESIS: Quarantine is associated with stress and depression leading to unhealthy diet and reduced physical activity. A diet poor in fruit and vegetables is frequent during isolation, with a consequent low intake of antioxidants and vitamins. However, vitamins have recently been identified as a principal weapon in the fight against the Cov-19 virus. Some reports suggest that Vitamin D could exert a protective effect on such infection. During quarantine, strategies to further increase home-based physical activity and to encourage adherence to a healthy diet should be implemented. The WHO has just released guidance for people in self-quarantine, those without any symptoms or diagnosis of acute respiratory illness, which provides practical advice on how to stay active and reduce sedentary behavior while at home. CONCLUSION: Quarantine carries some long-term effects on cardiovascular disease, mainly related to unhealthy lifestyle and anxiety. Following quarantine, a global action supporting healthy diet and physical activity is mandatory to encourage people to return to a good lifestyle routine.

Gender differences in the development of cardiac complications: a multicentre study in a large cohort of thalassaemia major patients to optimize the timing of cardiac follow-up.

We assessed whether male gender was associated with a higher risk of cardiac iron accumulation and fibrosis, heart dysfunction and complications in a large, multicentre cohort of thalassaemia major (TM) patients, in order to optimize the timing in cardiac follow-up. We considered 1711 TM patients (899 females, 31·09 ± 9·08 years), enrolled in the Myocardial Iron Overload in Thalassaemia Network. Clinical/instrumental data are recorded from birth to the first Cardiovascular Magnetic Resonance Imaging scan. Although having a similar risk of accumulating iron, males showed a significantly higher risk of developing cardiac dysfunction, heart failure, arrhythmias and cardiac complications overall, when compared to females (P < 0·0001). Up to 20-30 years of follow-up, the Kaplan-Meier curves for the outcomes for which the male sex was a significant prognosticator almost overlapped, whereas they clearly diverged after this period. In patients with follow-up longer than 20 years, males exhibited a significantly higher risk of ventricular dysfunction, heart failure, arrhythmias, and cardiac complications. Female patients may have an intrinsically better tolerance for iron toxicity. International guidelines suggest annual cardiac evaluation for thalassaemia patients. It is possible that female patients can be evaluated at longer intervals, thus reducing health costs.

Significance of the ionized calcium measurement to assess calcium status in osteopenic/osteoporosis postmenopausal outpatients.

INTRODUCTION: Evaluation of calcium status is important in the osteoporotic risk assessment. Although guidelines indicate total calcium (tCa) as first-line measurement, directly measured ionized calcium (m-iCa), considered as the gold standard, is more and more often required. Aim of this study is to evaluate the agreement between m-iCa, tCa and iCa calculated from a formula based on total calcium and albumin (c-iCa) in osteopenic/osteoporotic postmenopausal outpatients. METHODS: A total of 140 postmenopausal outpatients, 41 osteopenic (OPN) and 99 osteoporotic (OP) were enrolled. Levels of tCa, m-iCa, c-iCa, total protein and albumin, vitamin D (25-OHD), parathyroid hormone 1-84 (PTH), bone alkaline phosphatase, osteocalcin and serum collagen type 1 cross-linked C-telopeptide (CTX) were also measured. RESULTS: There were no statistically significant differences between OPN and OP groups regarding values of tCa, m-iCa, and c-iCa, 25-OHD and PTH. However, OP women had lower levels of CTX (p < 0.05). A significant direct correlation between m-iCa and tCa (r = 0.60, p < 0.001) and c-iCa (r = 0.61, p < 0.001) was found. Women with isolated hyper-m-iCa had similar DEXA parameter levels respect to the other patients. However, one patient with confirmed primary hyperparathyroidism presented hyper-m-iCa versus normal tCa and c-iCa values. CONCLUSIONS: The use of tCa could be sufficient to characterize the calcium status in postmenopausal outpatients, but reflexive calcium testing strategy for m-iCa test is necessary to women presenting the low or high extremes of tCa levels, or in women with suspected PHPT.

Evaluation of the Effects of the Metha® Short Stem on Periprosthetic Bone Remodelling in Total Hip Arthroplasties: Results at 48 Months.

INTRODUCTION: Total hip arthroplasty is one of the most performed procedures in orthopaedic surgery. Implantation of a prosthesis determines changes in the distribution of loads on the host bone, and this phenomenon, known as stress shielding, is related to the biomechanical characteristics of the implant. Usually stress shielding involves the proximal portion of the femur by reducing the mechanical strength and ability to withstand the transmitted loads. The aim of our study is to demonstrate how the use of a short hip stem reduces the stress shielding phenomenon to the proximal femur. MATERIALS AND METHODS: The study analyzed 20 patients undergoing hip prosthesis surgery with a short stem (Metha<, B. Braun Medical, Inc., Bethlehem, Pennsylvania) at the Ist Orthopaedic Division of Pisa University (between December 2008 and January 2010). Each patient was subjected to analysis of periprosthetic bone mineral density by a bone densitometry (dual emission X-ray absorptiometry [DEXA] with the metal removal software) at 0, 6, 12, 18, 24, and 36 months, following a protocol based on the evaluation of the changes of bone density in the seven Gruen zones. RESULTS: We recorded minimal changes in bone mineral density (BMD) at the level of the greater trochanter (-1.44%) and at the level of the calcar (-3.7%). BMD increased significantly after four years at the level of the lateral distal regions (R2 +9.6% - R3 + 12.4%) and at the level of the distal medial regions (R5 + 8.2% - R6 + 13.1%). We compared the results obtained with the literature data at 12 and 24 months with the same stem (Metha<). At 12 months follow up, we did not see a significant difference between our data and the data published in the literature. However, after 48 months of follow-up, we recorded significant differences in the curves of periprosthetic bone reabsorption at the level of the greater trochanter (Zone 1) and at the level of the calcar (Zone 7). DISCUSSION: The data obtained from our study are in agreement with other studies in the literature, which demonstrates how the use of short stems preserves the metaphyseal bone stock at the level of the proximal femur, reducing the stress shielding phenomenon. From our data, obtained at 24 months and confirmed at 36, stress shielding seems to minimally occur at the level of the calcar. At the level of the great trochanter, we saw a good load distribution that maintained the baseline BMD; these data are in opposition to the literature data that showed a high increase of BMD at the level of the calcar (+12.9%) and a decrease at the level of the great trochanter. From the analysis of the radiographic images of our cases, and of the cases published with the same stem, these differences in load transfer encountered between the great trochanter and the calcar seems to be related to the level of the femoral neck osteotomy and the consequent stem position (varus/valgus). CONCLUSION: We conclude that the amount of periprostetic bone reabsorption around the Metha< stem seems to be strictly related to the surgical technique and the final implant position.

The different role of sex hormones on female cardiovascular physiology and function: not only oestrogens.

Human response to different physiologic stimuli and cardiovascular (CV) adaptation to various pathologies seem to be gender specific. Sex-steroid hormones have been postulated as the major contributors towards these sex-related differences. This review will discuss current evidence on gender differences in CV function and remodelling, and will present the different role of the principal sex-steroid hormones on female heart. Starting from a review of sex hormones synthesis, receptors and CV signalling, we will summarize the current knowledge concerning the role of sex hormones on the regulation of our daily activities throughout the life, via the modulation of autonomic nervous system, excitation-contraction coupling pathway and ion channels activity. Many unresolved questions remain even if oestrogen effects on myocardial remodelling and function have been extensively studied. So this work will focus attention also on the controversial and complex relationship existing between androgens, progesterone and female heart.

Effects of ω-3 PUFAs supplementation on myocardial function and oxidative stress markers in typical Rett syndrome.

Rett syndrome (RTT) is a devastating neurodevelopmental disorder with a 300-fold increased risk rate for sudden cardiac death. A subclinical myocardial biventricular dysfunction has been recently reported in RTT by our group and found to be associated with an enhanced oxidative stress (OS) status. Here, we tested the effects of the naturally occurring antioxidants ω-3 polyunsaturated fatty acids (ω-3 PUFAs) on echocardiographic parameters and systemic OS markers in a population of RTT patients with the typical clinical form. A total of 66 RTT girls were evaluated, half of whom being treated for 12 months with a dietary supplementation of ω-3 PUFAs at high dosage (docosahexaenoic acid ~71.9 ± 13.9 mg/kg b.w./day plus eicosapentaenoic acid ~115.5 ± 22.4 mg/kg b.w./day) versus the remaining half untreated population. Echocardiographic systolic longitudinal parameters of both ventricles, but not biventricular diastolic measures, improved following ω-3 PUFAs supplementation, with a parallel decrease in the OS markers levels. No significant changes in the examined echocardiographic parameters nor in the OS markers were detectable in the untreated RTT population. Our data indicate that ω-3 PUFAs are able to improve the biventricular myocardial systolic function in RTT and that this functional gain is partially mediated through a regulation of the redox balance.

Ospemifene and vulvovaginal atrophy: an update of the clinical profile for post-menopausal women.

INTRODUCTION: The demand for effective and safe treatments of genitourinary syndrome (GSM) in post-menopausal women (PMW) is growing. Published data on the efficacy and safety of ospemifene (OSP) prompt an updated literature review to enlighten possible improvements in the GSM treatment. AREA COVERED: We searched articles published in English from 2010 to 2023 through Medline (PubMed) and Embase databases with Boolean terms: OSP, PMW, GSM, endometrium, breast cancer, cardiometabolic syndrome, bone metabolism, adherence to treatment, and patient satisfaction. We selected randomized controlled trials (RCTs) and observational and cross-sectional studies and completed the search manually. EXPERT OPINION: Of the 157 retrieved records, 25 primary studies met the inclusion criteria (15 regarding efficacy and safety, two for additional effects, and four for adherence and satisfaction with the OSP treatment). Seven RCTs involved nearly 5,000 patients, 10 out of 18 prospective observational studies 563, and six retrospective analyses 356,439. Evidence of OSP treatment in PMW with GSM relies on RCTs and remarkable real-world data. The 25 primary studies showcased the high clinical response to symptoms, the favorable safety profile of OSP with very few adverse events, a neutral impact on the endometrium, breast, bone, and thrombosis, and the possible improvement of cardiovascular risk factors.

Vulvovaginal atrophy in women with and without a history of breast cancer: Baseline data from the PatiEnt satisfactiON studY (PEONY) in Italy.

OBJECTIVES: To assess clinical characteristics of postmenopausal women with moderate/severe vulvovaginal atrophy, as well as its impact on sexual function, well-being, and quality of life, and to provide an overview of most used treatments. STUDY DESIGN: Ongoing longitudinal, observational study conducted in 17 Italian gynecology centers, involving women already treated or initiating a local vaginal estrogen therapy or ospemifene. We report baseline data for women with and without a history of breast cancer. Participants filled in self-reported questionnaires at study entry. MAIN OUTCOME MEASURES: Severity of vulvovaginal atrophy; ongoing treatments; patient-reported outcomes, including severity of symptoms, Day-to-Day Impact of Vaginal Aging (DIVA), Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), and SF-12® Health Survey. RESULTS: Overall, 334 women (20.4 % with a history of breast cancer) started or continued local therapy (61.1 %) or ospemifene (38.8 %) at study entry. Vulvovaginal atrophy was severe in 28.6 %, and was responsible for severe symptoms, particularly vulvar dryness with burning or irritation and pain during sexual intercourse. Both sexual dysfunction (FSFI≤26) (81.5 %) and sexual distress (FSDS-R ≥ 11) (74.4 %) were common. A reduction in the SF-12 mental component score was documented. Women with breast cancer more often had severe vulvovaginal atrophy (41.2 %), had more severe symptoms, and the impact of vaginal symptoms on emotional well-being, sexual functioning and self-concept/body image was greater. The majority of them (83.8 %) received ospemifene as a treatment. CONCLUSIONS: Moderate/severe vulvovaginal atrophy is a common, often neglected condition with an impact on QoL and sexuality, particularly in women with a history of breast cancer. It is important to alleviate the burden associated with the disease.

Maternal-fetal dyad beyond the phenomenology of pregnancy: from primordial cardiovascular prevention on out, do not miss this boat!

Pregnancy represents a stress test for every woman's cardiovascular (CV) system, and a pre-existing maternal unfavorable cardio-metabolic phenotype can uncover both adverse pregnancy outcomes and the subsequent development of cardiovascular disease (CVD) risk factors during and after pregnancy. Moreover, the maternal cardiac and extracardiac environment can affect offspring's cardiovascular health through a complex mechanism called developmental programming, in which fetal growth can be influenced by maternal conditions. This interaction continues later in life, as adverse developmental programming, along with lifestyle risk factors and genetic predisposition, can exacerbate and accelerate the development of CV risk factors and CVD in childhood and adolescence. The aim of this narrative review is to summarize the latest evidences regarding maternal-fetal dyad and its role on primordial, primary and secondary CV prevention.

Oxidative Stress and Antioxidant Status in Adult Patients with Transfusion-Dependent Thalassemia: Correlation with Demographic, Laboratory, and Clinical Biomarkers.

Iron overload in beta transfusion-dependent thalassemia (ß-TDT) may provoke oxidative stress and reduction of the antioxidant defenses, with serious consequences for the disease course and complications. The present study evaluated the oxidant/antioxidant status of ß-TDT patients and its correlation with demographic, clinical, laboratory, and instrumental biomarkers. The OXY-adsorbent assay and the d-ROMs (Diacron, Grosseto, Italy) were evaluated in 58 ß-TDT patients (mean age: 37.55 ± 7.83 years, 28 females) enrolled in the Extension-Myocardial Iron Overload in Thalassemia Network. Iron overload was quantified with R2* magnetic resonance imaging. Mean OXY was 323.75 ± 113.19 µmol HClO/mL and 39 (67.2%) patients showed a decreased OXY-Adsorbent level (<350 µmol HClO/mL), of whom 22 (37.9%) showed severely reduced levels. Mean d-ROMs was 305.12 ± 62.19 UA; 12 (20.7%) patients showed oxidative stress, and 4 (6.9%) elevated oxidative stress. OXY showed a significant negative correlation with global and segmental cardiac iron levels. D-ROMs levels significantly correlated with markers of cardiovascular risk (aging, glycemia, and N-terminal pro-B-type natriuretic peptide). Antioxidant depletion is frequent in ß-TDT patients, where OXY might serve as additive biomarker to assess heart iron status, whereas the d-ROMs might be helpful to assess the cardiovascular risk burden.

Clinical and histomorphometric soft tissue assessment comparing free gingival graft and a collagen matrix as alveolar-sealer materials: a randomized controlled pilot clinical trial.

OBJECTIVE: This study aimed to compare the alveolar sealing performance between free gingival graft (FGG) and porcine collagen membrane (MS) and qualitatively assess patient-centered outcomes via a visual analog scale. METHOD AND MATERIALS: Eighteen patients were randomly divided into control (FGG) and test (MS) groups. After extraction, all the alveoli were filled with bovine bone grafts (small granules) and sealed. Follow-up was during the immediate postoperative period and after 3, 7, 15, 30, 60, 90, and 120 days. After 180 days, before implant placement, tissue samples were obtained for histologic analysis. The epithelial tissues were morphometrically measured for each sample. Qualitative information on the patient's perception of the treatment was collected after 7 days. RESULTS: A faster healing was observed for the MS group. After 60 days, all the sites from the MS were partially healed, in contrast with only five from the FGG. The histologic results after 120 days showed for the FGG group a predominant acute inflammatory process, whereas chronic processes were observed for the MS group. The mean epithelial heights found for the FGG and MS were 535.69 µm and 495.33 µm, respectively (P = .54). The intragroup analysis showed significant variance among the data (P < .001) for both groups. The qualitative result showed statistically more significative comfort for the MS group (P < .05). CONCLUSION: Within the limitations of the study, both techniques effectively promote alveolar sealing. However, the visual analog scale result was superior and more significant for the MS group, with faster wound healing and lower discomfort.

Impact of COVID-19 on the cardiovascular health of women: a review by the Italian Society of Cardiology Working Group on 'gender cardiovascular diseases'.

The coronavirus disease 19 (COVID-19), due to coronavirus 2 (SARS-CoV-2) infection, presents with an extremely heterogeneous spectrum of symptoms and signs. COVID-19 susceptibility and mortality show a significant sex imbalance, with men being more prone to infection and showing a higher rate of hospitalization and mortality than women. In particular, cardiovascular diseases (preexistent or arising upon infection) play a central role in COVID-19 outcomes, differently in men and women. This review will discuss the potential mechanisms accounting for sex/gender influence in vulnerability to COVID-19. Such variability can be ascribed to both sex-related biological factors and sex-related behavioural traits. Sex differences in cardiovascular disease and COVID-19 involve the endothelial dysfunction, the innate immune system and the renin-angiotensin system (RAS). Furthermore, the angiotensin-converting enzyme 2 (ACE2) is involved in disease pathogenesis in cardiovascular disease and COVID-19 and it shows hormone-dependent actions. The incidence of myocardial injury during COVID-19 is sex-dependent, predominantly in association with a greater degree of inflammation and coagulation disorders among men. Its pathogenesis is not fully elucidated, but the main theories foresee a direct role for the ACE2 receptor, the hyperimmune response and the RAS imbalance, which may also lead to isolated presentation of COVID-19-mediated myopericarditis. Moreover, the latest evidence on cardiovascular diseases and their relationship with COVID-19 during pregnancy will be discussed. Finally, authors will analyse the prevalence of the long-covid syndrome between the two sexes and its impact on the quality of life and cardiovascular health.

Bone status and HCV infection in thalassemia major patients.

PURPOSE: Hepatitis C virus (HCV) infection increases the risk for osteoporosis but this relationship has not been investigated among multi-transfused patients with thalassemia major (TM). We cross-sectionally explored the association of HCV infection with bone mineral density (BMD), vitamin D, and bone turnover biomarkers in TM. METHODS: We considered 130 TM patients (41.89 ± 5.49 years, 67 females) enrolled in the E-MIOT (Extension-Myocardial Iron Overload in Thalassemia) Network. BMD measurements taken at the lumbar spine, femoral neck and total hip were expressed as Z-scores, with a BMD Z-score ≤ -2.0 indicating low bone mass. RESULTS: Z-scores were not associated with gender, iron overload indices, vitamin D levels, and biochemical bone turnover markers, but decreased with aging and in presence of hypogonadism and were directly correlated with body mass index (BMI). The prevalence of low bone mass was 70.7 %. Three groups of patients were identified: 78 who never contracted the infection (group 0), 72 who cleared HCV (group 1), and 29 with chronic HCV infection (CHC) (group 2). All Z-scores progressively decreased according to HCV status from group 0 to group 2. Osteocalcin levels were significantly lower in groups 2 and 1 than in group 0. CHC patients were more likely to have low bone mass compared to HCV naive patients, after adjusting for age, BMI, hypogonadism, and pancreatic iron. CONCLUSION: In TM, CHC appears as one additive risk factor for low bone mass and osteocalcin may play a role in this association.

How to evaluate resting ECG and imaging in children practising sport: a critical review and proposal of an algorithm for ECG interpretation.

The athlete's heart is a well-known phenomenon in adults practising competitive sports. Unfortunately, to date, most of the studies on training-induced cardiac remodelling have been conducted in adults and the current recommendations refer mainly to adult individuals. However, an appropriate interpretation of resting ECG and imaging in children practising sports is crucial, given the possibility of early detect life-threatening conditions and managing therapy and eligibility to sports competitions in the rapidly growing paediatric athlete population. While several articles have been published on this topic in adult athletes, a practical guide for the clinical evaluation of paediatric athletes is still missing. In this critical review, we provided a comprehensive description of the current evidence on training-induced remodelling in paediatric athletes with a practical approach for clinicians on how to interpret the resting 12-lead ECG and cardiac imaging in the paediatric athlete. Indeed, given that training may mimic potential cardiovascular disorders, clinicians evaluating children practising sports should pay attention to the risk of missing a diagnosis of a life-threatening condition. However, this risk should be balanced with the risk of overdiagnosis and unwarranted disqualification from sports practice, when interpreting an ECG as pathological while, on the contrary, it may represent a physiological expression of athlete's heart. Accordingly, we proposed an algorithm for the evaluation of normal, borderline, and abnormal ECG findings that can be useful for the readers for their daily clinical practice.

Sex Differences in Repolarization Markers: Telemonitoring for Chronic Heart Failure Patients.

Aging and chronic heart failure (CHF) are responsible for the temporal inhomogeneity of the electrocardiogram (ECG) repolarization phase. Recently, some short period repolarization-dispersion parameters have been proposed as markers of acute decompensation and of mortality risk in CHF patients. Some important differences in repolarization between sexes are known, but their impact on ECG markers remains unstudied. The aim of this study was to evaluate possible differences between men and women in ECG repolarization markers for the telemonitoring of CHF patients. METHOD: 5 min ECG recordings were collected to assess the mean and standard deviation (SD) of the following variables: QT end (QTe), QT peak (QTp), and T peak to T end (Te) in 215 decompensated CHF (age range: from 49 to 103 years). Thirty-day mortality and high levels of NT-pro BNP (<75 percentile) were considered markers of decompensated CHF. RESULTS: A total of 34 patients (16%) died during the 30-day follow-up, without differences between sexes. Women showed a more preserved ejection fraction and higher LDL and total cholesterol levels. Among female patients, implantable cardioverter devices, statins, and antiplatelet agents were less used. Data for Te mean showed increased values among deceased men and women compared to survival, but TeSD was shown to be the most reliable marker for CHF reacutization in both sexes. CONCLUSION: TeSD could be considered a risk factor for CHF worsening and complications for female and male patients, but different cut offs should be taken into account.
