Introduction: The changes associated with aging are multidimensional and multifactorial, with the geriatric syndrome of frailty being its most problematic and complex expression. This syndrome leads to vulnerability, disproportionate changes in health status, and functional decline, making its effective identification and comprehensive management necessary., Objective: To describe the sociodemographic, clinical, and functional characteristics of older adults with cardiovascular risk in Southwestern Colombia., Materials and Methods: This study has an observational, cross-sectional, and analytical design. The selected population included older adults enrolled in a cardiovascular and metabolic risk program in Popayán (Cauca). A multivariate analysis explored the relationship between frailty and certain sociodemographic, clinical, and functional variables., Results: A total of 293 older adults participated, primarily women (69.6%), with an average age of 71.23 years. Among them, 77.1% were classified as independent in basic activities and 56.3% in instrumental activities of daily living, with autonomy being more prevalent among men. Additionally, 71.1% of women and 43.8% of men were classified as prefrail. The bivariate analysis identified a relationship between frailty and variables such as sex, age, marital status, educational level, occupation, calf circumference, functional capacity, instrumental capacity, and family functionality. The multivariate analysis showed a higher frailty/prefrailty prevalence (55%) in women., Conclusions: Most participants were classified as prefrail; dependency and frailty were more prevalent in women, suggesting the need for preventive strategies and interventions from a gender-differentiated approach.

Background: Pediatric heart transplantation (HT) continues to be limited by the shortage of donor organs, distance constraints, and the number of potential donor offers that are declined due to the presence of multiple risk factors., Methods: We report a case of successful pediatric HT in which multiple risk factors were mitigated through a combination of innovative donor utilization improvement strategies., Results: An 11-year-old, 25-kilogram child with cardiomyopathy and pulmonary hypertension, on chronic milrinone therapy and anticoagulated with apixaban, was transplanted with a heart from a Hepatitis C virus positive donor and an increased donor-to-recipient weight ratio. Due to extended geographic distance, an extracorporeal heart preservation system (TransMedics™ OCS Heart) was used for procurement. No significant bleeding was observed post-operatively, and she was discharged by post-operative day 15 with normal biventricular systolic function. Post-transplant Hepatitis C virus seroconversion was successfully treated., Conclusions: Heart transplantation in donors with multiple risk factor can be achieved with an integrative team approach and should be taken into consideration when evaluating marginal donors in order to expand the current limited donor pool in pediatric patients., (© 2023 Wiley Periodicals LLC.)

Adult patients on left ventricular assist device (LVAD) support have increased morbidity and mortality after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. There are no reported clinical data describing outcomes among pediatric patients on ventricular assist device (VAD) support infected with SARS-CoV-2. We conducted a retrospective study using the Advanced Cardiac Therapies Improving Outcomes Network (ACTION) registry to evaluate patient characteristics and clinical outcomes after SARS-CoV-2 infection. A total of 22 children on VAD support (median age at infection 10.6 years) from 16 centers tested positive for SARS-CoV-2. Cardiomyopathy (59.1%) and congenital heart disease (40.9%) were the most common primary diagnoses. The type of support included LVAD in 19 (86.4%), biventricular assist device (BIVAD) in one (4.5%), and single ventricle VAD in two (9%) patients. At the time of infection, 50% were outpatients, 23% were inpatients on a general cardiology floor, and 27% were in the cardiac intensive care unit (CICU). Most patients (82%) were symptomatic at time of diagnosis, but only 13% required escalation of respiratory support, and 31% received SARS-CoV-2 therapies. Notably, no mortality occurred, and significant morbidity was rare after SARS-CoV-2 infection in pediatric patients on VAD support., Competing Interests: Disclosure: ACTION receives funding from Berlin Heart Inc, Abbott Laboratories, and Medtronic.

Currently, ginger is one the most consumed plants when dealing with the treatments of various illnesses. So far, it is known that various biologically active molecules, such as gingerols, shogaols and zingerone, among others, are the main responsible for specific biological activities, opening a new window for its utilization as a nutraceutical in foods. In pioneering extraction processes, solvent extraction has been initially used for these applications; however, the drawbacks of this typical extraction method compared with other emergent separation techniques make it possible for the exploration of new extraction pathways, including microwave, ultrasound, supercritical, subcritical and pressurized-assisted extraction, along with three phase partitioning, high-speed counter current chromatography and magnetic solid phase extraction. To the best of our knowledge, there is no report documenting the recent studies and cases of study in this field. Therefore, we comprehensively review the progress and the latest findings (over the last five years) on research developments, including patents and emerging extraction methods, aiming at the purification of biologically active molecules (gingerols, shogaols and zingerone) contained in ginger. Over the course of this review, particular emphasis is devoted to breakthrough strategies and meaningful outcomes in ginger components extraction. Finally, dosage and safety concerns related to ginger extracts are also documented., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Background: Chronic right ventricular (RV) apical pacing in patients with congenital complete atrioventricular block (CCAVB) is associated with left ventricle (LV) dyssynchrony and dysfunction. Hence, alternative pacing sites are advocated. The aim of this study was to compare LV function using STE in selected patients with LV epicardial pacing (LVEp) vs. RV transvenous pacing (RVSp)., Methods: This was a single-center, retrospective study in patients with CCAVB who underwent permanent pacemaker implant at age ≤ 18 years. Age- and gender-matched patients with a normal heart anatomy and function served as the control group. LV function was comprehensively assessed by conventional 2D Echocardiography and speckle-tracking echocardiography (STE)., Results: We included 24 patients in the pacemaker group [27.6% male, mean age of 17.1 at last follow-up, follow-up duration of 8.7 years, RVSp (n = 9; 62.5%)] compared to 48 matched healthy controls. Shortening fraction (SF) and ejection fraction (EF) were normal and similar between cases and controls. However, STE detected abnormal LV function in the pacemaker group compared to controls. The former demonstrated lower/abnormal, Peak Longitudinal Strain myocardial (PLS Myo) [- 12.0 ± 3.3 vs. - 18.1 ± 1.9, p < 0.001] and Peak Longitudinal Strain endocardial (PLS endo) [- 16.1 ± 4.1 vs. 1.7 ± 1.7, p < 0.001]. STE parameters of LV function were significantly more abnormal in LVEp vs. RVSp subgroup as demonstrated by lower values for PLS Myo (- 10.1 ± 3.2 vs. - 13.1 ± 2.9, p = 0.03) and PLS Endo (- 13.8 ± 4.4 vs. - 17.5 ± 3.3, p = 0.03)., Conclusion: STE was more sensitive in detecting subtle differences in LV function relative to standard conventional 2D echocardiography (SF and EF) in selected patients with CCAVB and a permanent pacemaker. Furthermore, STE demonstrated that transvenous RV septal pacing was associated with better LV systolic function preservation than LV epicardial pacing for comparable post-implant intervals., (© 2023.

Berlin Heart EXCOR ventricular assist device (VAD) implantation in children is widely used as bridge-to-heart transplantation. Berlin left ventricular assist device (LVAD) support as a bridge to recovery is rare. There is a scarcity of literature describing systematic evaluation in pediatric VAD explantation. Patient 1. A 3 month old boy presented with acute heart failure secondary to myocarditis. An echocardiogram demonstrated severely depressed left ventricular function. He required ECMO cannulation and was decannulated 11 days later. He continued to be hemodynamically unstable and required Berlin LVAD implantation with the intent to bridge to transplantation. Patient 2. A 3 month old boy presented initially with a heart rate of 250 beats/min and an electrocardiogram showed multifocal atrial tachycardia. An echocardiogram showed severely decreased left ventricular function. He was placed on ECMO due to unstable hemodynamics. He did not tolerate ECMO decannulation due to persistent chaotic atrial rhythm and underwent Berlin LVAD implantation with the intent to bridge to transplantation. After both patients showed evidence of myocardial recovery, they underwent a weaning protocol that includes: screening, trial-off with echocardiography, and trial-off in the catheterization suite. Our patients met the criteria and underwent successful explantation. Explantation of VAD can be successfully performed even in young children with appropriate candidate selection and a multidisciplinary and systematic approach., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © ASAIO 2022.)

Hypoglycemic encephalopathy constitutes a critical presentation of severely diminished glucose levels. We present the case of a 53-year-old male patient with a history of diabetes mellitus with hypoglycemic encephalopathy and MRI findings of bilateral middle cerebellar peduncle lesions. Common findings of hypoglycemic encephalopathy described in the literature consist of bilateral compromise of the cerebral cortex, basal ganglia, hippocampus, and long tracts of white matter. The cerebellum and brainstem are usually not affected. This is the ninth report of cerebellar peduncle compromise with hypoglycemia. As increasing evidence regarding prognosis estimation of lesion distribution arises, we consider it important to report the different cases of rare patterns of compromise., (© 2022 The Authors.)

Dilated cardiomyopathy is the most common presentation of cardiomyopathy in children with 20-35% of patients having an identified genetic component. There are more than 30 genes implicated in the pathogenesis of dilated cardiomyopathy. We present the first report of a female infant with dilated cardiomyopathy with a genetic variant in the dispatched RND transporter family member 1 gene.

Cardiac amyloidosis is a rare cause of cardiomyopathy, reported exclusively in adults. We report the first known case presenting in childhood. A 12-year-old boy presented with syncope and diagnosed with ventricular non-compaction by echocardiography. Eventual genetic testing confirmed a TTR gene mutation associated with hereditary transthyretin amyloidosis., (© 2021.

Introduction: The number of adults requiring surgeries for CHD is increasing. We sought to evaluate the utility of the vasoactive-ventilation-renal (VVR) score as a predictor of prolonged length of stay in adults following CHD surgery., Methods: This is a retrospective review of 158 adult patients who underwent CHD surgery involving cardiopulmonary bypass. VVR score was calculated upon arrival to ICU and every 6 hours for the first 48 hours post-operatively. Our primary outcome was prolonged length of stay defined as hospital length of stay greater than 75th percentile for the cohort (≥8 days)., Results: The study cohort had a median age of 25.6 years (18-60 years), and 83 (52.5%) were male. The groups with and without prolonged length of stay were comparable in age, gender, race, and surgical severity score. VVR score was significantly higher at all time points in the group with prolonged length of stay. The first post-operative day peak VVR score ≥13 had a sensitivity of 81% and specificity of 75% for predicting prolonged length of stay (p = 0.0001). On regression analysis, peak VVR score during the first day was independently associated with prolonged length of stay., Conclusions: Peak VVR score during the first post-operative day was a strong predictor of prolonged length of stay in adults following CHD surgery.

A phase III dengue vaccine trial including 9- to 16-year-olds in Latin America (NCT01374516) was ongoing at the time of a Zika outbreak. We explored interactions between dengue and Zika, in the context of dengue vaccination. Symptomatic virologically confirmed Zika (VCZ) was evaluated using acute-phase sera from febrile participants (January 2013-March 2018). Neutralizing antibody geometric mean titers (GMTs) were evaluated pre- and post-Zika outbreak (months 25 and 72) in 2,000 randomly selected participants. Baseline dengue serostatus was determined using the plaque reduction neutralization test or inferred post hoc using nonstructural protein 1 IgG ELISA at M13 (case-cohort analysis). Vaccine efficacy against VCZ and serologically suspected Zika (SSZ) was estimated. Overall, 239/10,157 (2.4%) acute-phase samples were VCZ positive during the study. Dengue vaccine efficacy against VCZ was 27.8% (95% CI: 0.3; 47.7) among baseline dengue-seropositive participants. No vaccine effect was evident against SSZ. Zika antibody GMTs increased from pre- to post-Zika epidemic, with smaller increases observed for participants who were dengue seropositive at baseline than for those who were dengue seronegative: post-/pre-Zika GMT ratios for baseline dengue-seropositive participants were 21.5 (vaccine group) and 30.8 (placebo); and for dengue seronegatives, 88.1 and 89.5, respectively. Dengue antibody GMTs post-Zika were higher in dengue vaccine and placebo recipients with SSZ than those without SSZ in both dengue seropositives and seronegatives. Dengue vaccine did not enhance symptomatic Zika illness in dengue-seropositive individuals, rather it reduced the risk of VCZ. Zika infection boosted preexisting vaccine-induced or naturally occurring dengue-neutralizing antibodies.

Background: We previously described an increased immune response 28 days after a booster dose of the live, attenuated, tetravalent dengue vaccine (CYD-TDV) in healthy adolescents and adults in Latin America (CYD64, NCT02623725). This follow-up study evaluated immune response persistence and safety of a CYD-TDV booster dose up to Month (M) 24 post-booster., Methods: This study included 250 participants who previously received 3 primary doses of CYD-TDV in the CYD13 (NCT00993447) and CYD30 (NCT01187433) studies, and who were randomized 4-5 years later to receive a CYD-TDV booster or placebo (3:1). Dengue neutralizing antibodies against the parental dengue virus strains were assessed using the plaque reduction neutralization test (PRNT50) at M6, M12, and M24 post-booster. Post-booster memory B-cell responses were assessed in a subset of participants using the FluoroSpot assay up to M12 post-booster., Results: In the CYD-TDV group (n = 187), dengue neutralizing antibody geometric mean titers (GMTs) declined from the peak at day 28 through to M24 for all serotypes. GMTs at M24 were similar to those at pre-booster among baseline dengue seropositives. A similar trend was observed for baseline dengue seronegatives, albeit at a lower magnitude. Previous vaccination-induced detectable B-cell memory responses in seropositives and seronegatives that decreased to pre-booster levels at M12 post-booster. The CYD-TDV booster dose was well-tolerated., Conclusions: In baseline dengue seropositives, following a CYD-TDV booster dose administered 4-5 years after primary immunization, dengue neutralizing antibody GMTs and B-cell memory responses peaked in the short-term before gradually decreasing over time. A CYD-TDV booster dose could improve protection against dengue during outbreak periods.

Introduction: Differences in the lateral and medial portions from quadriceps muscular activation during the execution of the jump can become a neuromuscular risk factor raising knee dynamic valgus and increasing the risk for anterior cruciate ligament injury. Objective: To determine the difference in the activation of the lateral and medial vastus using surface electromyography during single-leg jumps in the sagittal and frontal plane in female athletes. Materials and methods: This was a quantitative, cross-sectional study. A total of 64 female athletes participated. We carried out anthropometric measurements, vertical and lateral single-leg jump tests with the evaluation of vastus medialis and lateral electromyographic activation during the tests and iliotibial band flexibility assessment. Results: There was a statistically significant relationship (p≤0.05) between the body mass index, fat percentage, and vertical single-leg jump power. We also found statistical significance (p≤0.05), with greater activation of the lateral vastus in the right lower limb vertical jump and in the lateral jump in both lower limbs. Conclusion: The athletes presented differences in quadriceps activation, showing higher lateral vastus activation in most of the single-leg jumps, both in the sagittal and frontal plane. This may increase the risk for suffering knee injuries during sports practice.

Trigeminal Schwannomas are less than 1% of intracranial tumors, of which only 7% have a cystic component. We documented 2 cases of males with cystic trigeminal Schwannomas, their symptoms, the diagnosis process and the imaging characteristics. In addition, a review of the literature is performed, with emphasis on the radiological classification of this rare entity, that constitutes a diagnostic challenge for the radiologist, who has an essential role in the approach to the disease and therefore in its management., (© 2019 The Authors.

Multiple sclerosis (MS) is the most prevalent chronic inflammatory disease of the central nervous system (CNS), affecting more than 2 million people worldwide. It is characterized by brain and spinal cord involvement. There are the relapsing remitting MS (RRMS), primary progressive MS (PPMS), and secondary progressive MS (SPMS) phenotypes. There is a subgroup of RRMS patients who have a more aggressive disease course marked by a rapid accumulation of physical and cognitive deficit, despite treatment with 1 or more disease modifying drugs (DMTs). In the past, this disease phenotype was called "aggressive" MS (AMS); it is now called highly active MS (HAMS). It is generally agreed that the severe nature of this phenotype requires different treatment decisions. Unfortunately, there is no consensus on the definition of AMS or the treatment algorithm. In this article we review HAMS in relation to its definition and the treatments available., (Copyright © 2019. Published by Elsevier B.V.)

Thirty sediment samples from four different beaches along Bahia Solano and Nuquí (Department of Chocó) of eastern Colombia, with tourism and gold mining activities, were analysed to estimate the concentrations of fourteen different acid leachable metals. Metal distribution patterns showed elevated concentrations of Co, Cr, Cu, Pb and Zn compared with the upper continental crust values. Calculation of geochemical indices confirmed that the enrichment is due to periodic gold mining activities (severe to extremely severe enrichment of Cu, Zn, V, Co, Cr and Pb) along with natural (geological) contributions (minor and moderate enrichment of Ca, Mg, Fe, Ti, Mn and Li). Potential ecological risk index revealed that Pb posed the highest risk. Our results together with a global comparison suggest that the observed metal enrichments are mainly caused by mining and to a lesser extent by tourism in this region, thus instigating continuous monitoring of metal concentrations in this region., (Copyright © 2018 Elsevier Ltd.

A baseline study on metal concentrations in sediments was initiated from the Sodwana Bay and St. Lucia, adjacent to marine protected areas (MPAs) of South Africa. They were analysed to identify the acid leachable metal (ALM) (Fe, Mg, Mn, Cr, Cu, Mo, Ni, Co, Pb, Cd, Zn and Hg) concentration pattern. Metal distribution in 65 sediment samples exhibits higher abundances of Cr, Mo, Cd and Hg compared to the Upper Continental Crust. We relate the enrichment of these metals to beach placer deposits and activities related to former gold mining. Geochemical indices affirmed that Cr and Hg caused contamination, and Hg posed ~90% harmful effect on the biological community. These beach sediments, however, host lower metal concentrations compared to many worldwide beaches and other beaches in South Africa. This study suggests that it is largely unaffected by human activities, however, the overabundance of Hg demands regular monitoring., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Brown tumours are highly vascular lytic bone lesions found in primary and secondary hyperparathyroidism. The brown term is given due to the red-brown colour of the tissue, which is due to the accumulation of hemosiderin. The case is presented of a 29 year-old male with chronic renal failure, who had a mass in the tip of the ring finger after a trauma of 4 months onset, which had increased progressively in size and pain. He was treated surgically, by amputation, with no recurrence 10 months after the surgery., (Copyright © 2016 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.)

Background: In light of the increasing rate of dengue infections throughout the world despite vector-control measures, several dengue vaccine candidates are in development., Methods: In a phase 3 efficacy trial of a tetravalent dengue vaccine in five Latin American countries where dengue is endemic, we randomly assigned healthy children between the ages of 9 and 16 years in a 2:1 ratio to receive three injections of recombinant, live, attenuated, tetravalent dengue vaccine (CYD-TDV) or placebo at months 0, 6, and 12 under blinded conditions. The children were then followed for 25 months. The primary outcome was vaccine efficacy against symptomatic, virologically confirmed dengue (VCD), regardless of disease severity or serotype, occurring more than 28 days after the third injection., Results: A total of 20,869 healthy children received either vaccine or placebo. At baseline, 79.4% of an immunogenicity subgroup of 1944 children had seropositive status for one or more dengue serotypes. In the per-protocol population, there were 176 VCD cases (with 11,793 person-years at risk) in the vaccine group and 221 VCD cases (with 5809 person-years at risk) in the control group, for a vaccine efficacy of 60.8% (95% confidence interval [CI], 52.0 to 68.0). In the intention-to-treat population (those who received at least one injection), vaccine efficacy was 64.7% (95% CI, 58.7 to 69.8). Serotype-specific vaccine efficacy was 50.3% for serotype 1, 42.3% for serotype 2, 74.0% for serotype 3, and 77.7% for serotype 4. Among the severe VCD cases, 1 of 12 was in the vaccine group, for an intention-to-treat vaccine efficacy of 95.5%. Vaccine efficacy against hospitalization for dengue was 80.3%. The safety profile for the CYD-TDV vaccine was similar to that for placebo, with no marked difference in rates of adverse events., Conclusions: The CYD-TDV dengue vaccine was efficacious against VCD and severe VCD and led to fewer hospitalizations for VCD in five Latin American countries where dengue is endemic.

Background: Since the introduction of highly active antiretroviral therapy (HAART) for prevention of mother-to-child transmission of human immunodeficiency virus (HIV) in pregnancy in the United States, the time of seroreversion in infants born to HIV-infected mothers has not been documented. The objective of this study was to determine the timing of clearance of HIV antibodies and to identify any associated biological and clinical factors., Methods: A retrospective analysis of infants who remained uninfected after perinatal HIV exposure was performed. Infant and maternal medical records from January 2000 to December 2007 were reviewed and the time of seroreversion was estimated using methods for censored survival data., Results: In total, 744 infants were included in the study, with prenatal data available for 551 mothers. The median age of seroreversion was 13.9 months, and 14% of infants remained seropositive after 18 months, 4.3% after 21 months, and 1.2% after 24 months. Earlier age of seroreversion was associated with higher immunoglobulin G (IgG) levels at 3-7 months of age (P = .0029) and a higher rate of IgG change over the next 6 months of life (P = .003). Infants born by vaginal delivery were more likely to serorevert at a younger age (P = .0052), and maternal exposure to protease inhibitors was associated with a later age of seroreversion (P = .026)., Conclusions: Clearance of HIV antibodies in uninfected infants was found to occur at a later age than has been previously reported. Fourteen percent of the infants had persistence of HIV antibodies at or beyond 18 months of age.

Purpose: Long-term immunogenicity and safety of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine when administered to adolescent girls was evaluated., Methods: This open-label, follow-up study (NCT00316706) was conducted in 31 centers in Taiwan, Germany, Honduras, Panama, and Colombia. In the initial study (NCT00196924), 1,035 girls aged 10-14 years received the HPV-16/18 AS04-adjuvanted vaccine at 0, 1, and 6 months. Here, geometric mean titers (GMTs) of antibodies against HPV-16, HPV-18, and monophosphoryl lipid A (MPL), a component of the AS04 Adjuvant System, were reported up to month 48., Results: In the according-to-protocol immunogenicity cohort (N = 563), GMTs at month 48 in initially seronegative participants were 2,374.9 (95% confidence interval: 2,205.7-2,557.0) EL.U/mL for anti-HPV-16 and 864.8 (796.9-938.4) EL.U/mL for anti-HPV-18, that is, six- and threefold higher than the plateau level in a reference study demonstrating vaccine efficacy in young women (age, 15-25 years). All participants remained seropositive for anti-HPV-16 and anti-HPV-18 at month 48. Most participants (81.8%) were seropositive for anti-MPL antibodies before vaccination. Anti-MPL antibody titers in initially seropositive participants increased initially, and then declined. Most initially seronegative participants for anti-MPL seroconverted; 69.6% remained seropositive at month 48, with anti-MPL antibody titers similar to the natural background level. The vaccine was generally well tolerated. No serious adverse events were considered related to vaccination., Conclusions: In adolescent girls, the HPV-16/18 AS04-adjuvanted vaccine produces anti-HPV-16 and anti-HPV-18 antibody titers that are maintained for up to 4 years at higher levels than those in young women in whom vaccine efficacy against cervical lesions was demonstrated., (Copyright © 2012.

Purpose: Immunization of girls against oncogenic human papillomavirus (HPV) types before sexual debut is important for cervical cancer prevention. This phase III blinded, randomized, controlled trial in adolescent girls assessed safety of the HPV-16/18 AS04-adjuvanted vaccine., Methods: Girls (mean age 12 years) in 12 countries received the HPV-16/18 L1 virus-like particle AS04-adjuvanted vaccine (N = 1,035) or hepatitis A virus vaccine as control (N = 1,032) at 0, 1, and 6 months. The primary objective was to compare the occurrence of serious adverse events (SAEs) between groups. HPV-16 and HPV-18 antibody titers were assessed by enzyme-linked immunosorbent assay post-vaccination., Results: Up to study month 7, 11 girls in the HPV-16/18 vaccine group reported 14 SAEs and 13 girls in the control group reported 15 SAEs. The difference in SAE incidence between groups was .20% (95% CI, -.78, 1.20). No SAE in the HPV-16/18 vaccine group was considered related to vaccination or led to withdrawal. The incidence of solicited local and general symptoms up to 7 days post-vaccination was moderately higher with the HPV-16/18 vaccine than with control. The incidence of unsolicited symptoms, new onset of chronic diseases, and medically significant conditions was similar between groups. All girls seroconverted for both antigens after three doses of the HPV-16/18 vaccine; geometric mean titers were 19,882.0 and 8,262.0 EU/mL for anti-HPV-16 and -18 antibodies, respectively, in initially seronegative girls., Conclusions: The HPV-16/18 AS04-adjuvanted vaccine was generally well tolerated and immunogenic when administered to young adolescent females, the primary target of organized vaccination programs., (Copyright 2010 Society for Adolescent Medicine.

Heart failure is a progressive and fatal disease process. Arrhythmias and progressive cardiac dysfunction account for most of the morbidity and mortality in patients with heart failure. In general, the physiologic mechanisms responsible for progressive myocyte dysfunction, remodeling, and arrhythmias involve signaling mechanisms that alter myocardial gene expression. These changes in gene expression are complex and involve contractile proteins, ion channels, Ca++ handling, apoptosis, cell metabolism, the extracellular matrix, signal transduction pathways, and growth factors.
