Divergent responses of serum testosterone and cortisol in athlete men after a marathon race

Physical exercise alters homeostasis, as it requires prompt mobilization of metabolic sources. In this study, we measured serum testosterone (T) and cortisol (C) levels and the muscle-wastage enzymes CK, CKMB and LDH in 20 healthy male athletes (ages 25 to 40 years) in response to a marathon race (42.2 km). Venous blood samples were drawn in 3 different periods: (i) in the morning, 48 h before the competition (control), (ii) at the end of the race (end), and (iii) in the next morning, 20 h after the race (recovery). At the end, T was significantly lower (from 673 to 303 ng/dl) and C higher (from 20.3 to 42.5 µg/dl) as compared to the control period. At recovery, both were virtually identical to control levels. CK, CKMB and LDH were significantly higher at the end of the competition and even higher in the recovering period (except for CKMB), characterizing muscle wastage. CK and LDH disclosed a significant negative correlation with T (-0.412 and -0.546, respectively), whereas CKMB correlated positively with C (0.4521). We conclude that the inverse correlation observed between T and C levels, and the pattern of CK, CKMB and LDH increase, allow us to confirm that a marathon race may cause a marked physical stress, resulting in a distinct hormonal imbalance and severe cellular damage.O exercício físico altera a homeostase, pois requer rápida mobilização de fontes metabólicas. Neste estudo, analisamos a resposta dos níveis séricos de testosterona (T) e cortisol (C) e das enzimas de desgaste muscular CK, CKMB e LDH, em 20 atletas masculinos sadios (25 a 40 anos), participantes de uma maratona (42,2 km). Coletas de sangue venoso foram feitas em 3 períodos: (i) pela manhã, 48 h antes da maratona (controle), (ii) logo após o término da corrida (final) e (iii) na manhã seguinte, 20 h após a realização da prova (recuperação). Ao final, T estava significantemente mais baixa (de 673 para 303 ng/dl) e C mais elevado (de 20,3 para 42,5 µg/dl) que no período controle. Na recuperação, ambos praticamente retornaram aos níveis basais. CK, CKMB e LDH estavam significantemente mais elevadas ao final da corrida e mais ainda na recuperação (exceto a CKMB), caracterizando o desgaste muscular. Enquanto CK e LDH apresentaram significante correlação negativa com a T (-0,412 e -0,546, respectivamente), CKMB correlacionou-se positivamente com o C (0,4521). Concluímos que a correlação inversa entre T e C, e o comportamento das enzimas CK, CKMB e LDH, permite comprovar que uma corrida de maratona causa intenso stress físico, provocando desequilíbrio hormonal e lesão celular severa.Universidade Federal de São Paulo (UNIFESP) Departamento de Medicina Centro de Medicina da Atividade Física e do EsporteUNIFESP, Depto. de Medicina Centro de Medicina da Atividade Física e do EsporteSciEL

Early improvement of glycaemic control after virus clearance in patients with chronic hepatitis C and severe liver fibrosis: a cohort study

HCV has been recognized as the cause of chronic hepatitis C (CHC) since 1990. CHC is associated with progressive liver damage and extrahepatic conditions. Direct antiviral agents (DAAs), approved in 2014, have shown effectiveness in eradicating HCV in most patients. However, little is known about the effect of viral eradication on hepatic and extra-hepatic damage. We performed a historical cohort study of patients with HCV-related liver diseases who achieved SVR from March 2015 to October 2016 at INMI Lazzaro Spallanzani liver Unit in Rome (Italy). Repeated measures of glycaemia were analysed through a multilevel analysis framework to assess short time kinetics of blood glucose level at different times after therapy and for different levels of HCV viremia. The analysis included 205 patients. A model assessing temporal kinetics and variation of glycaemia according to HCV viremia provided evidence that blood glucose levels significantly dropped in patients with diabetes achieving SVR. Most of the variations occurred at 3-5 weeks of therapy (-17.96 mg/dL; p<0.001) and in coincidence with HCV clearance (-13.92 mg/dL; p<0.001). A weak, non-statistically significant reduction was observed in normoglycemic patients. Our study provides evidence that DAAs therapy may significantly improve glycaemic control in patients with CHC achieving SVR even when liver diseases are already established

impact of frequency and severity of rhinitis on lung function in children and adolescents without asthma

Introducción. Se han observado alteraciones espirométricas en pacientes con rinitis, sin asma, proporcionales al grado clínico de la rinitis establecido por la guía Allergic Rhinitis and its Impact on Asthma (ARIA). Recientemente se ha validado una nueva clasificación de la rinitis como ARIA modificada (ARIAm), que disocia la forma moderada de la grave. Se desconoce el impacto de la rinitis sobre la función pulmonar considerando su frecuencia y gravedad por separado. Objetivos. Determinar las posibles alteraciones de la función pulmonar y su potencial reversibilidad al broncodilatador en niños y adolescentes con rinitis alérgica y no alérgica sin asma, de acuerdo a su frecuencia (intermitente y persistente) y gravedad (leve, moderada y grave) establecida según ARIAm. Población y métodos. Estudio observacional, analítico de corte transversal, que incluyó pacientes de ambos sexos, entre 5 y 18 años, con rinitis alérgica y no alérgica, sin asma. Se realizó espirometría por curva flujo-volumen y se analizó la existencia de anormalidades en la función pulmonar y la respuesta broncodilatadora en relación con el grado de rinitis por ARIAm ajustando un modelo logístico. Se consideró un valor de p<0,05 para establecer significación estadística. Resultados. Se incluyeron 189 pacientes. En 42 (22,2%) se observó al menos un parámetro alterado en la función pulmonar. Los pacientes con rinitis persistente exhibieron mayor afectación de la función pulmonar que los de grado intermitente (p=0,0257). El defecto funcional fue más frecuente en las formas grave y moderada que en el grado leve (p=0,0052) y fue independiente de la condición de atopia (p=0,1574 para frecuencia y p =0,5378 para gravedad). No se encontró diferencia en la reversibilidad al broncodilatador entre los grupos (p=0,1859 y p=0,0575, respectivamente). Conclusiones. La alteración de la función pulmonar se asoció con rinitis persistente. Fue más prevalente en las formas moderada y grave pero no existieron diferencias significativas entre ambas. El defecto funcional se demostró tanto en rinitis alérgica como no alérgica.Background: Subclinical spirometric abnormalities have been observed in patients with rhinitis without asthma, proportional to the clinical grade established by Allergic Rhinitis and Its Impact on Asthma (ARIA) guideline. Recently has been validated a new criteria of rhinitis classification designed as ARIA modified (ARIAm), which allow to discrimination moderate to severe grades. Rhinitis impact on lung function according to frequency and severity considering separately is unknown. Objectives: To investigate possible subclinical alterations in lung function and bronchodilator reversibility in children and adolescents with allergic and non-allergic rhinitis without asthma, according to the frequency and severity criteria of rhinitis classified by ARIAm. Methods: In an observational cross sectional study we included children and adolescents aged 5 to 18 years with symptoms of allergic and non-allergic rhinitis without asthma. Spirometry was performed by flow-volume curve and we analyzed the abnormalities in respiratory function and bronchodilator response in relation to clinical grade of rhinitis by ARIAm using an adjusted logistic model. A p value Results: We studied 189 patients; 42 (22.2%) had some spirometric abnormalities. Patients with persistent rhinitis had greater impairment of lung function compared to intermittently grade (p = 0.0257). The functional defect was more frequent in rhinitis severe and moderate than mild grade (p = 0.0052) and was independent of atopy status both frequency (p = 0.1574) and severity (p=0.5378). There was no difference in bronchodilator reversibility between groups (p = 0.1859 and p = 0.0575 respectively). Conclusion: Impaired lung function was associated with persistent rhinitis. It was more prevalent in moderate and severe rhinitis, but there wasn’t a significant difference between them. The functional defect was demonstrated in both allergic and nonallergic rhinitis.Fil: Saranz, Ricardo J.. Universidad Católica de Córdoba. Facultad de Medicina.

Surgical site infection after caesarean section. Space for post-discharge surveillance improvements and reliable comparisons

Surgical site infections (SSI) after caesarean section (CS) represent a substantial health system concern. Surveying SSI has been associated with a reduction in SSI incidence. We report the findings of three (2008, 2011 and 2013) regional active SSI surveillances after CS in community hospital of the Latium region determining the incidence of SSI. Each CS was surveyed for SSI occurrence by trained staff up to 30 post-operative days, and association of SSI with relevant characteristics was assessed using binomial logistic regression. A total of 3,685 CS were included in the study. A complete 30 day post-operation follow-up was achieved in over 94% of procedures. Overall 145 SSI were observed (3.9% cumulative incidence) of which 131 (90.3%) were superficial and 14 (9.7%) complex (deep or organ/space) SSI; overall 129 SSI (of which 89.9% superficial) were diagnosed post-discharge. Only higher NNIS score was significantly associated with SSI occurrence in the regression analysis. Our work provides the first regional data on CS-associated SSI incidence, highlighting the need for a post-discharge surveillance which should assure 30 days post-operation to not miss data on complex SSI, as well as being less labour intensive

Compliance with evidence-based clinical guidelines in the management of acute biliary pancreatitis: the MANCTRA-1 study protocol

Despite existing evidence-based practice guidelines for the management of biliary acute pancreatitis (AP), the clinical compliance with recommendations is overall poor. Studies in this field have identified significant discrepancies between evidence-based recommendations and daily clinical practice. The most commonly reported gaps between clinical practice and AP guidelines include the indications for CT scan, need and timing of artificial nutritional support, indications for antibiotics, and surgical/endoscopic management of biliary AP. The MANCTRA-1 (coMpliAnce with evideNce-based cliniCal guidelines in the managemenT of acute biliaRy pancreAtitis) study is aiming to identify the areas for quality improvement that will require new implementation strategies. The study primary objective is to evaluate which items of the current AP guidelines are commonly disregarded and if they correlate with negative clinical outcomes according to the different clinical presentations of the disease. We attempt to summarize the main areas of sub-optimal care due to the lack of compliance with current guidelines to provide the basis for introducing a number of bundles in AP patients' management to be implemented during the next years. The MANCTRA-1 study is an international multicenter, retrospective cohort study with the purpose to assess the outcomes of patients admitted to hospital with a diagnosis of biliary AP and the compliance of surgeons worldwide to the most up-to-dated international guidelines on biliary AP.

Exploring the facilitators and barriers to using an online infertility risk prediction tool (FoRECAsT) for young women with breast cancer: A qualitative study protocol

INTRODUCTION: As cancer treatments may impact on fertility, a high priority for young patients with breast cancer is access to evidence-based, personalised information for them and their healthcare providers to guide treatment and fertility-related decisions prior to cancer treatment. Current tools to predict fertility outcomes after breast cancer treatments are imprecise and do not offer individualised prediction. To address the gap, we are developing a novel personalised infertility risk prediction tool (FoRECAsT) for premenopausal patients with breast cancer that considers current reproductive status, planned chemotherapy and adjuvant endocrine therapy to determine likely post-treatment infertility. The aim of this study is to explore the feasibility of implementing this FoRECAsT tool into clinical practice by exploring the barriers and facilitators of its use among patients and healthcare providers. METHODS AND ANALYSIS: A cross-sectional exploratory study is being conducted using semistructured in-depth telephone interviews with 15-20 participants each from the following groups: (1) premenopausal patients with breast cancer younger than 40, diagnosed within last 5 years, (2) breast surgeons, (3) breast medical oncologists, (4) breast care nurses (5) fertility specialists and (6) fertility preservation nurses. Patients with breast cancer are being recruited from the joint Breast Service of three affiliated institutions of Victorian Comprehensive Cancer Centre in Melbourne, Australia-Peter MacCallum Cancer Centre, Royal Melbourne Hospital and Royal Women's Hospital, and clinicians are being recruited from across Australia. Interviews are being audio recorded, transcribed verbatim and imported into qualitative data analysis software to facilitate data management and analyses. ETHICS AND DISSEMINATION: The study protocol has been approved by Melbourne Health Human Research Ethics Committee, Australia (HREC number: 2017.163). Confidentiality and privacy are maintained at every stage of the study. Findings will be disseminated through peer-reviewed scholarly and scientific journals, national and international conference presentations, social media, broadcast media, print media, internet and various community/stakeholder engagement activities
