Exercise Blood Pressures Are Lower After Aquatic Compared To Land Treadmill Training

Exercise blood pressures are lower after aquatic compared to land treadmill training Alex T. Carradine1, Brad S. Lambert1, Nicolas P. Greene2, Travis W. Constanzo1, Steven E. Martin1, Stephen F. Crouse (FACSM)1. Texas A&M University, College Station, TX. 2University of Virginia, Charlottesville, VA. Traditional treadmill training has been shown to moderately decrease exercise blood pressures but the degree to which aquatic running alters exercise blood pressures has not been fully investigated. PURPOSE: To compare the exercise blood pressure responses after land treadmill (LTM) training to an equivalent volume of aquatic treadmill training (ATM). METHODS: We tested blood pressure responses to the Bruce treadmill protocol PRE and POST 12-wks of matched volume training on LTM (n= 9♂,13♀, age=43±3 yrs, weight=88.1±3.6 kg) or ATM (n=18♂, 17♀, age=45±2 yrs, weight=90.6±3.0 kg). Systolic (SBP), diastolic (DBP), pulse pressure (PP) and mean arterial pressure (MAP) were analyzed using a 2 (ATM or LTM) x 2 (PRE & POST) ANOVA repeated for the training time at rest, 3 stages of the exercise protocol, and 1 and 5 minutes of recovery; Tukey\u27s post hoc tests were used as follow-up for significant interactions, α=0.05. RESULTS: VO2max increased significantly 11-15% with training in both groups. Significant training changes for MAP shown in Table (mmHg, mean±SE); SBP and PP paralleled these results. Significance remained after covarying for BMI, %body fat, and age.

These data suggest ATM may provide a superior benefit over LTM for promoting said reduction

The role of molar mass in achieving isotropy and interlayer strength in Mat-Ex printed polylactic acid

There has been extensive research in the field of material-extrusion (Mat-Ex) 3D printing to improve the inter-layer bonding process. Much research focusses on how various printing conditions may be detrimental to weld strength; many different feedstocks have been investigated along with various additives to improve strength. Surprisingly, there has been little attention directed toward how fundamental molecular properties of the feedstock, in particular the average molar mass of the polymer, may contribute to microstructure of the weld. Here we showed that weld strength increases with decreasing average molar mass, contrary to common observations in specimens processed in more traditional ways, e.g., by compression molding. Using a combination of synchrotron infra-red polarisation modulation microspectroscopy measurements and continuum modelling, we demonstrated how residual molecular anisotropy in the weld region leads to poor strength and how it can be eradicated by decreasing the relaxation time of the polymer. This is achieved more effectively by reducing the molar mass than by the usual approach of attempting to govern the temperature in this hard to control non-isothermal process. Thus, we propose that molar mass of the polymer feedstock should be considered as a key control parameter for achieving high weld strength in Mat-Ex

Dyslipidemia and chronic inflammation markers are correlated with telomere length shortening in Cushing's syndrome

INTRODUCTION: Cushing's syndrome (CS) increases cardiovascular risk (CVR) and adipocytokine imbalance, associated with an increased inflammatory state. Telomere length (TL) shortening is a novel CVR marker, associated with inflammation biomarkers. We hypothesized that inflammatory state and higher CVR in CS might be related to TL shortening, as observed in premature aging. - AIM: to evaluate relationships between TL, CVR and inflammation markers in CS. - METHODS: in a cross-sectional study, 77 patients with CS (14 males, 59 pituitary-, 17 adrenal- and 1 ectopic-origin; 21 active disease) and 77 age-, gender-, smoking-matched controls were included. Total white blood cell TL was measured by TRF-Southern technique. Clinical data and blood samples were collected (lipids, adrenal function, glucose). Adiponectin, interleukin-6 (IL6) and C-reactive protein (CRP) were available in a subgroup of patients (n=32). Correlations between TL and clinical features were examined and multiple linear regression analysis was performed to investigate potential predictors of TL. - RESULTS: dyslipidemic CS had shorter TL than non-dyslipidemic subjects (7328±1274 vs 7957±1137 bp, p<0.05). After adjustment for age and body mass index, cured and active CS dyslipidemic patients had shorter TL than non-dyslipidemic CS (cured: 7187±1309 vs 7868±1104; active: 7203±1262 vs 8615±1056, respectively, p<0.05). Total cholesterol and triglycerides negatively correlated with TL (r-0.279 and -0.259, respectively, p<0.05), as well as CRP and IL6 (r-0.412 and -0.441, respectively, p<0.05). No difference in TL according the presence of other individual CVR factors (hypertension, diabetes mellitus, obesity) were observed in CS or in the control group. Additional TL shortening was observed in dyslipidemic obese patients who were also hypertensive, compared to those with two or less CVR factors (6956±1280 vs 7860±1180, respectively, p<0.001). Age and dyslipidemia were independent negative predictors of TL. -CONCLUSION :TL is shortened in dyslipidemic CS patients, further worse if hypertension and/or obesity coexist and is negatively correlated with increased inflammation markers. Increased lipids and a "low" grade inflammation may contribute to TL shortening and consequently to premature ageing and increased morbidity in CS

Colouration in amphibians as a reflection of nutritional status : the case of tree frogs in Costa Rica

Colouration has been considered a cue for mating success in many species; ornaments in males often are related to carotenoid mobilization towards feathers and/or skin and can signal general health and nutrition status. However, there are several factors that can also link with status, such as physiological blood parameters and body condition, but there is not substantial evidence which supports the existence of these relationships and interactions in anurans. This study evaluated how body score and blood values interact with colouration in free-range Agalychnis callidryas and Agalychnis annae males. We found significant associations between body condition and plasmatic proteins and haematocrit, as well as between body condition and colour values from the chromaticity diagram. We also demonstrated that there is a significant relation between the glucose and plasmatic protein values that were reflected in the ventral colours of the animals, and haematocrit inversely affected most of those colour values. Significant differences were found between species as well as between populations of A. callidryas, suggesting that despite colour variation, there are also biochemical differences within animals from the same species located in different regions. These data provide information on underlying factors for colouration of male tree frogs in nature, provide insights about the dynamics of several nutrients in the amphibian model and how this could affect the reproductive output of the animals

Compound double ileoileal and ileocecocolic intussusception caused by lipoma of the ileum in an adult patient: A case report

<p>Abstract</p> <p>Introduction</p> <p>The initial diagnosis of intussusception in adults very often can be missed and cause delayed treatment and possible serious complications. We report the case of an adult patient with complicated double ileoileal and ileocecocolic intussusception.</p> <p>Case presentation</p> <p>A 46-year-old Caucasian man was transferred from the gastroenterology service to the abdominal surgery service with severe abdominal pain, nausea, and vomiting. An abdominal ultrasound, barium enema, and abdominal computed tomography scan revealed an intraluminal obstruction of his ascending colon. Plain abdominal X-rays showed diffuse air-fluid levels in his small intestine. A double ileoileal and ileocecocolic intussusception was found during an emergent laparotomy. A right hemicolectomy, including resection of a long segment of his ileum, was performed. The postoperative period was complicated by acute renal failure, shock liver, and pulmonary thromboembolism. Our patient was discharged from the hospital after 30 days. An anatomical pathology examination revealed a lipoma of his ileum.</p> <p>Conclusions</p> <p>Intussusception in adults requires early surgical resection regardless of the nature of the initial cause. Delayed treatment can cause very serious complications.</p

Body composition after endogenous (Cushing's syndrome) and exogenous (rheumatoid arthritis) exposure to glucocorticoids

Exposure to chronic glucocorticoid (GC) excess determines changes in body composition. The aim of the study was to compare body composition in women exposed to endogenous hypercortisolism (Cushing's syndrome, CS), exogenous glucocorticoid treatment (rheumatoid arthritis, RA) and controls. Fifty-one CS women, 26 RA women treated with low-dose prednisone (5 mg/day or 10 mg/2 days), and 78 female controls were included. Fourteen CS patients were hypercortisolemic, 37 in remission (10 required hydrocortisone substitution after surgery). Body composition parameters were measured by dual-energy X-ray absorptiometry scanning (DEXA). RA patients had a greater waist-hip ratio (WHR) (p<0.01), less lean body mass (LBM) (p<0.01), and lumbar bone mineral density (BMD) (p<0.01) than controls. CS patients, globally and those with cured disease, had more total fat (both percentage and kg) and trunk fat percentage, and less whole body-BMD than RA patients (p<0.05, p<0.01, p<0.05, respectively). Active CS patients had less whole body-BMD and more LBM than RA patients (p<0.05, p=0.01, respectively). Cured CS patients not taking hydrocortisone had more total fat [both percentage (p<0.05) and kg (p<0.05)], trunk fat percentage (p<0.05), lumbar BMD (p<0.01) than RA patients. Cured CS patients requiring hydrocortisone only differed from RA patients by smaller WHR (p<0.01). All the differences in BMD disappeared when the data were reanalyzed including only the estrogen-deficient groups. Hypercortisoliof CS determines an irreversible increase in body fat, greater than in RA. Endogenous and exogenous exposure to GC negatively affects body composition by increasing the WHR. There appears to be no additional effect on BMD in estrogen-deficient women

Factores de riesgo cardiovascular entre pacientes con síndrome de Cushing, curados y no curados con respecto a un grupo control

Objetivos: Describir los factores de riesgo cardiovascular que se presentan en el paciente con Síndrome de Cushing (SC), para establecer programas educativos adaptados a este grupo de pacientes. Método: El ámbito de estudio se desarrolló en el Hospital de Sant Pau, en el Servicio de Endocrinología. Se extrajeron datos de las Historias Clínicas de los pacientes que fueron visitados en consultas con diagnóstico de SC en el 2005, realizándose una recogida retrospectiva. No se excluyó ningún paciente, independientemente de los años de duración de la patología, de las opciones terapéuticas o del tratamiento farmacológico recibido, incluyendo todos los pacientes con SC. Elaboramos una hoja de recogida de datos demográficos, clínicos (peso, índice de masa corporal, tensión arterial, perímetro abdominal) y analíticos (lípidos, glicemia); para el tratamiento informático se utilizó el programa SPSS. Resultados: El perímetro abdominal fue mayor en pacientes no curados (100.8 ±13.9cm) que en controles (89±12.8cm) (p<0.05). Respecto al peso no se encontraron diferencias significativas entre controles (69,9±13,3Kg), curados (69,9±16,5Kg) y no curados (76,4±16,5Kg). El IMC tampoco reflejó diferencias en los tres grupos en estudio: control (26,5±5,2), curados (27,8±6,4) y no curados (29,3±3,8). El colesterol fue más alto en los pacientes curados (5.90±0.92mmol/L) que en controles (5.38±1.07mmol/L) (p<0.05), al igual que los triglicéridos (1.20±0.51mmol/L versus controles 1.05±0.56mmol/L; p<0.05). Ambos grupos de pacientes presentaron presión sistólica mayor que los controles (curados,128.3±16.7mmHg p<0.05; no curados,134.1±13mmHg, p<0.001). Los no curados (78.6±9.2mmHg) presentaron además presión diastólica mayor que los controles (72.3±8.6, p<0.05) Fig.3. No observamos diferencias en la glicemia basal entre los 3 grupos de pacientes. Conclusiones: Los pacientes con SC, curados de su hipercortisolismo y con enfermedad activa presentan mayor riesgo cardiovascular y metabólico, comparados con el grupo control. La enfermera educadora deberá contemplar e incluir en los programas de prevención secundaria a dichos pacientes, para promocionar hábitos saludables, prevenir y controlar sus factores de riesgo.

2012 Activity Report of the Regional Research Programme on Hadrontherapy for the ETOILE Center

2012 is the penultimate year of financial support by the CPER 2007-2013 for ETOILE's research program, sustained by the PRRH at the University Claude Bernard. As with each edition we make the annual review of the research in this group, so active for over 12 years now. Over the difficulties in the decision-making process for the implementation of the ETOILE Center, towards which all our efforts are focussed, some "themes" (work packages) were strengthened, others have progressed, or have been dropped. This is the case of the eighth theme (technological developments), centered around the technology for rotative beam distribution heads (gantries) and, after being synchronized with the developments of ULICE's WP6, remained so by ceasing its activities, coinciding also with the retirement of its historic leader at IPNL, Marcel Bajard. Topic number 5 ("In silico simulations") has suffered the departure of its leader, Benjamin Ribba, although the work has still been provided by Branka Bernard, a former postdoctoral fellow in Lyon Sud, and now back home in Croatia, still in contract with UCBL for the ULICE project. Aside from these two issues (and the fact that the theme "Medico-economical simulations" is now directly linked to the first one ("Medical Project"), the rest of the teams are growing, as evidenced by the publication statistics at the beginning of this report. This is obviously due to the financial support of our always faithful regional institutions, but also to the synergy that the previous years, the European projects, the arrival of the PRIMES LabEx, and the national France Hadron infrastructure have managed to impulse. The Rhone-Alpes hadron team, which naturally includes the researchers of LPC at Clermont, should also see its influence result in a strong presence in France Hadron's regional node, which is being organized. The future of this regional research is not yet fully guaranteed, especially in the still uncertain context of ETOILE, but the tracks are beginning to emerge to allow past and present efforts translate into a long future that we all want to see established. Each of the researchers in PRRH is aware that 2013 will be (and already is) the year of great challenge : for ETOILE, for the PRRH, for hadron therapy in France, for French hadrontherapy in Europe (after the opening and beginning of treatments in the German [HIT Heidelberg, Marburg], Italian [CNAO, Pavia] and Austrian [MedAustron, Wien Neuerstadt]) centers. Let us meet again in early 2014 for a comprehensive review of the past and a perspective for the future ..

Telomere length analysis in Cushing's syndrome

Introduction: Hypercortisolism in Cushing's syndrome (CS) is associated with increased morbidity and mortality. Hypercortisolism also occurs in chronic depressive disorders and stress, where telomere length (TL) is shorter than in controls. We hypothesized that shortening of telomere might occur in CS and contribute to premature aging and morbidity. - Aim: To investigate TL in CS patients compared with controls. - Methods: Seventy-seven CS patients (14 males, 59 pituitary, 17 adrenal, and one ectopic; 21 with active disease) were compared with 77 gender-, age-, and smoking-matched controls. Fifteen CS were evaluated longitudinally, during active disease and after remission of hypercortisolism. Leukocyte TL was measured by telomere restriction fragment-Southern technique. Clinical markers were included in a multiple linear regression analysis to investigate potential predictors of TL. - Results : Mean TL in CS patients and controls was similar (7667 vs 7483 bp, NS). After adjustment for age, in the longitudinal evaluation, TL was shorter in active disease than after remission (7273 vs 7870, P<0.05). Age and dyslipidemia were negative predictors (P<0.05), and total leukocyte count was a positive predictor for TL (P<0.05). As expected, a negative correlation was found between TL and age (CS, R=−0.400 and controls, R=−0.292; P<0.05). No correlation was found between circulating cortisol, duration of exposure to hypercortisolism or biochemical cure and TL. - Conclusion : Even though in the cross-sectional comparison of CS and controls no difference in TL was found, in the longitudinal evaluation, patients with active CS had shorter TL than after biochemical cure of hypercortisolism. These preliminary results suggest that hypercortisolism might negatively impact telomere maintenance. Larger studies are needed to confirm these findings
