Exercise Capacity and Pulmonary Capacitance Are Attenuated in Patients with Nonalcoholic Steatohepatitis / 대한스포츠의학회지

Purpose@#The study was to investigate exercise capacity (peak oxygen uptake [peak VO2 ]) and pulmonary capacitance (GXcap), which is an estimate of pulmonary vascular capacitance, in patients with nonalcoholic steatohepatitis (NASH). @*Methods@#This study utilized a database of patients with NASH (n=26 [17 male and 9 female], aged 58.9±4.3 years) and healthy individuals (n=23 [12 male and 11 female, aged 58.6±7.9 years) who underwent a maximal exercise test on a recumbent cycle ergometer (Corival; Lode) in our laboratory. During cardiopulmonary exercise tests, breathing patterns and respiratory gas exchange including breathing efficiency (VE/VCO2 ) and end-tidal CO2 (PETCO2 ) were measured. In addition, peak VO2 was obtained via averaging the last 30 seconds at peak level and GXcap was obtained by calculation as follows: GXcap=oxygen pulse (O2 pulse)×PETCO2. @*Results@#The NASH group demonstrated reduced peak VO2 relative to the healthy group (17.5±8.4 mL/kg/min vs. 34±10.2 mL/kg/min, respectively; p＜ 0.05). In addition, there was a higher VE/VCO2 relationship in the NASH group relative to the healthy group (34.9±5.5 vs. 32.2±4.0, respectively; p＜ 0.05) and lower PETCO2 in the NASH group compared to the healthy group (32.8±4.0 mm Hg vs. 35.3±3.8 mm Hg, respectively; p＜ 0.05). Furthermore, the NASH group showed lower GXcap than the healthy group (456±150 vs. 551±202, respectively; p＜ 0.05). @*Conclusion@#Patients with NASH had reduced exercise capacity and pulmonary vascular capacitance relative to age-matched healthy adults and this may contribute to pulmonary pathophysiology in NASH.

Recomendaciones clínicas para el manejo de pacientes oncológicos en el marco de la pandemia COVID-19 / Clinical Recommendations For The Management Of Cancer Patients In The Context Of The COVID-19 Pandemic

La enfermedad por la nueva cepa de Coronavirus (COVID-19) ha sido catalogada como una pandemia por la OMS. En el Perú, se decretó estado de emergencia nacional y aislamiento social obligatorio desde el 15 de marzo. Los sistemas de salud a nivel mundial han sufrido un gran impacto debido la infección por COVID-19, lo cual obligó a los sistemas de salud, sociedades y asociaciones médicas a diseñar estrategias de intervención priorizada para dar continuidad a la atención de los pacientes en áreas COVID-19 y áreas libres de COVID-19. El paciente con cáncer es catalogado como vulnerable y representa un factor de riesgo para complicaciones, como ingreso a unidad de cuidados intensivos, intubación y muerte temprana por infección por COVID-19. Es así como la Asociación de Médicos Ex-Residentes de Oncología Médica (AMEROM), ha realizado esfuerzos para poder realizar recomendaciones adaptables a nuestro sistema de salud, con la finalidad de dar continuidad a la atención priorizada de los pacientes con cáncer. Mediante la metodología modificada de consenso de expertos, bajo el sustento bibliográfico, se han generado recomendaciones en diferentes etapas de la pandemia, llegando a un consenso final con recomendaciones clínicas para el manejo de pacientes oncológicos en el marco de la pandemia COVID-19 en Perú, con el fin de brindar información útil para los profesionales de la salud. El presente artículo indica los procesos con los que se llegaron a los acuerdos para dictar las recomendaciones y generar el orden de prioridad adoptado por AMEROM.

The disease by the new coronavirus strain (COVID-19) has been classified as apandemic by the WHO. In Peru, a state of national emergency and compulsory socialisolation had been declared since 15 March. Global health systems have been greatlyimpacted by COVID-19, which forced health systems, societies and medicalassociations to design prioritized intervention strategies to provide continuity of patientcare in infected areas and COVID-19-free areas. A cancer patient is classified asvulnerable and represents a risk factor for complications due to COVID-19, such asadmission to the intensive care unit, intubation, and early death due to infection due toCOVID-19. This is how the Asociación de Médicos Ex Residentes de OncologíaMédica (AMEROM), has endeavored to give recommendations adaptable to our healthsystem, to continue with the prioritized care of cancer patients. Through the modifiedmethodology of expert consensus, based on the literature, recommendations have beengenerated at different stages of the pandemic, reaching a final consensus of clinicalrecommendations for the management of cancer patients in the framework of theCOVID-19 pandemic in Peru, to provide useful information to health professionals.This article indicates the processes by which agreements were reached to makerecommendations and generate the order of priority adopted by AMEROM.

Prevalence and risk factors for neck pain among health care workers.

Background: Work related neck pain (WRNP) is common among professionals. Its cause is multifactorial and results in loss of productivity and avoidable morbidity. Aims & Objectives: To estimate the prevalence and risk factors of WRNP among the support staff of a tertiary hospital. Material & Methods: 558 support staff were randomly selected to estimate the prevalence of neck pain. Staff with severe WRNP were then included in a nested case control study to identify risk factors. Results: 37% of workers reported neck pain in the preceding 3 months. Female gender, improper posture, jobs requiring repetitive movements, perception of decreased job control, high body mass index and psychosocial stress were identified as the significant risk factors. Conclusion: Better ergonomics, improving the perception of job control and encouraging micro breaks during the work time may decrease WRNP.

Comfort and exertion while using filtering facepiece respirators with exhalation valve and an active venting system among male military personnel

<p><b>INTRODUCTION</b>This study aimed to determine if disposable filtering facepiece respirators (FFRs) that come with an exhalation valve (EV) and a novel active venting system (AVS) provided greater perceived comfort and exertion when compared to standard N95 FFRs without these features among male military personnel performing prolonged essential outdoor duties.</p><p><b>METHODS</b>We used a randomised open-label controlled crossover study design to compare three FFR options: (a) standard FFR; (b) FFR with EV; and (c) FFR with EV+AVS. Male military personnel aged between 18 and 20 years completed a questionnaire at the start of outdoor duty (baseline), after two hours of standardised non-strenuous outdoor duty and after 12 hours of duty divided into two-hour work-rest cycles. Participants rated the degree of discomfort, exertion and symptoms using a five-point Likert scale. The association between outcomes and types of FFR was assessed using a multivariate ordered probit mixed-effects model.</p><p><b>RESULTS</b>For a majority of the symptoms, study participants gave FFR with EV and FFR EV+AVS significantly better scores than standard FFR. Both FFR with EV and FFR with EV+AVS had significantly less discomfort (FFR with EV+AVS: 91.1%; FFR with EV: 57.6%) and exertion (FFR with EV+AVS: 83.5%; FFR with EV: 34.4%) than standard FFR. FFR with EV+AVS also had significantly better scores for exertion (53.4%) and comfort (39.4%) when compared to FFR with EV.</p><p><b>CONCLUSION</b>Usage of FFR with EV+AVS resulted in significantly reduced symptoms, discomfort and exertion when compared to FFR with EV and standard FFR.</p>

Isolation and molecular characterization of Thraustochytrium strain isolated from Antarctic Peninsula and its biotechnological potential in the production of fatty acids

ABSTRACT Thraustochytrids are unicellular protists belonging to the Labyrinthulomycetes class, which are characterized by the presence of a high lipid content that could replace conventional fatty acids. They show a wide geographic distribution, however their diversity in the Antarctic Region is rather scarce. The analysis based on the complete sequence of 18S rRNA gene showed that strain 34-2 belongs to the species Thraustochytrium kinnei, with 99% identity. The total lipid profile shows a wide range of saturated fatty acids with abundance of palmitic acid (16:0), showing a range of 16.1-19.7%. On the other hand, long-chain polyunsaturated fatty acids, mainly docosahexaenoic acid and eicosapentaenoic acid are present in a range of 24-48% and 6.1-9.3%, respectively. All factors analyzed in cells (biomass, carbon consumption and lipid content) changed with variations of culture temperature (10 °C and 25 °C). The growth in glucose at a temperature of 10 °C presented the most favorable conditions to produce omega-3fatty acid. This research provides the identification and characterization of a Thraustochytrids strain, with a total lipid content that presents potential applications in the production of nutritional supplements and as well biofuels.

TGF-beta receptor mediated telomerase inhibition, telomere shortening and breast cancer cell senescence

Human telomerase reverse transcriptase (hTERT) plays a central role in telomere lengthening for continuous cell proliferation, but it remains unclear how extracellular cues regulate telomerase lengthening of telomeres. Here we report that the cytokine bone morphogenetic protein-7 (BMP7) induces the hTERT gene repression in a BMPRII receptor- and Smad3-dependent manner in human breast cancer cells. Chonic exposure of human breast cancer cells to BMP7 results in short telomeres, cell senescence and apoptosis. Mutation of the BMPRII receptor, but not TGFbRII, ACTRIIA or ACTRIIB receptor, inhibits BMP7-induced repression of the hTERT gene promoter activity, leading to increased telomerase activity, lengthened telomeres and continued cell proliferation. Expression of hTERT prevents BMP7-induced breast cancer cell senescence and apoptosis. Thus, our data suggest that BMP7 induces breast cancer cell aging by a mechanism involving BMPRII receptor- and Smad3-mediated repression of the hTERT gene.

Expression of von Willebrand factor, pulmonary intravascular macrophages, and Toll-like receptors in lungs of septic foals

Sepsis causes significant mortality in neonatal foals; however, there is little data describing the cellular and molecular pathways of lung inflammation in septic foals. This study was conducted to characterize lung inflammation in septic foals. Lung tissue sections from control (n = 6) and septic (n = 17) foals were compared using histology and immunohistology. Blinded pathologic scoring of hematoxylin and eosin stained samples revealed increased features of lung inflammation such as thickened alveolar septa and sequestered inflammatory cells in septic foals. Septic foal lungs showed increased expression of von Willebrand factor in blood vessels, demonstrating vascular inflammation. Use of MAC387 antibody to detect calprotectin as a reflection of mononuclear cell infiltration revealed a significant increase in their numbers in alveolar septa of lungs from septic foals compared to those from control foals. The mononuclear cells appeared to be mature macrophages and were located in the septal capillaries, suggesting they were pulmonary intravascular macrophages (PIMs). Finally, lungs from septic foals showed increased expression of Toll-like receptor 4 and 9 in mononuclear cells relative to the control. Taken together, this study is the first to show the expression of inflammatory molecules and an increase in PIMs in lungs from foals that died from sepsis.

Poultry litter of wood shavings and/or sugarcane bagasse: animal performance and bed quality / Cama de viruta de madera y/o bagazo de caña de azúcar para pollo: desempeño animal y calidad de la cama / Cama composta por maravalha e/ou bagaço de cana de açúcar para frangos: desempenho animal e qualidade da cama

Background: litter provides comfort to animals while improving productive performance and carcass quality. Objective: this study evaluated broiler performance, incidence of contact dermatitis, and quality of poultry litter of wood shavings and/or sugarcane bagasse (SB) after five consecutive flocks. Methods: two thousand birds were raised in five consecutive flocks composed of 400 chicks each. The experiment was set in a completely randomized design with five treatments and four repetitions. The treatments consisted of substituting wood shavings with different levels of SB (0, 25, 50, 75, and 100%). Results: litter density, pH, dry matter content, total nitrogen, and phosphorus did not vary between treatments. However, substituting wood shavings with SB increased moisture retention capacity of the litter and ammonia production. Neither carcass lesions nor productive performance, with the exception of weight gain and feed conversion ratio in the fifth flock, differed between treatments. Conclusions: substituting 75% of wood shavings with SB maintained litter quality and improved poultry performance.

Antecedentes: la cama propicia el confort y mejora el desempeño productivo y la calidad de la canal de los pollos de engorde. Objetivo: el objetivo del presente estudio fue evaluar el desempeño productivo de pollos de engorde, la incidencia de dermatitis de contacto en la canal y la calidad de la cama de pollo compuesta de viruta de madera y/o bagazo de caña de azúcar (SB), usada en cinco lotes consecutivos. Métodos: dos mil aves fueron criadas en cinco lotes consecutivos, cada uno constituido por 400 pollitos, en un diseño completamente aleatorizado con cinco tratamientos y cuatro repeticiones. Los tratamientos consistieron en diferentes niveles de sustitución de viruta de madera con SB (0, 25, 50, 75 y 100%). Resultados: la densidad, pH y contenidos de materia seca, nitrógeno total y fósforo no variaron entre los tratamientos. Sin embargo, sustituir viruta de madera con SB aumentó la capacidad de retención de humedad y la cantidad de amoníaco volatilizado en el galpón. Ni las lesiones en la canal y ni el desempeño productivo, con excepción de la ganancia de peso y conversión alimentaria en el quinto lote, difirieron entre los tratamientos. Conclusiones: sustituir 75% de la viruta de madera con SB mantuvo la calidad de la cama y mejoró el desempeño productivo de las aves.

Antecedentes: cama de frango propicia conforto e melhora o desempenho produtivo e a qualidade da carcaça das aves. Objetivo: este estudo avaliou o desempenho produtivo de frangos de corte, a incidência de dermatite de contato na carcaça e a qualidade da cama de frango composta de maravalha e/ou bagaço de cana (SB), usada em cinco lotes consecutivos. Métodos: duas mil aves foram criadas em cinco lotes consecutivos, compostos de 400 pintinhos cada, em delineamento inteiramente casualizado com cinco tratamentos e quatro repetições. Os tratamentos consistiram de diferentes níveis de substituição de maravalha com BC (0, 25, 50, 75 e 100%). Resultados: densidade, pH e teores de matéria seca, nitrogênio total e fósforo não variaram entre os tratamentos. Entretanto, substituir maravalha com SB aumentou a capacidade de retenção de umidade e a quantidade de amônia volatilizada no galpão. Nem as lesões na carcaça e nem o desempenho produtivo, com exceção do ganho de peso e conversão alimentar no quinto lote, diferiram entre os tratamentos. Conclusões: substituir 75% da maravalha com SB manteve a qualidade da cama e melhorou o desempenho produtivo das aves.

The influence of stimulus phase duration on discomfort and electrically induced torque of quadriceps femoris

BACKGROUND: Although a number of studies have compared the influence of different electrical pulse parameters on maximum electrically induced torque (MEIT) and discomfort, the role of phase duration has been poorly investigated. OBJECTIVE: To examine the variation in muscle torque and discomfort produced when electrically stimulating quadriceps femoris using pulsed current with three different phase durations in order to establish whether there are any advantages or disadvantages in varying the phase duration over the range examined. METHOD: This is a two repeated-measures, within-subject study conducted in a research laboratory. The study was divided into 2 parts with 19 healthy young adults in each part.In part 1, MEIT was determined for each phase duration (400, 700, and 1000 µs), using a biphasic pulsed current at a frequency of 50 Hz. In part 2, stimulus amplitude was increased until the contractions reached 40% of maximum voluntary isometric contraction (MVIC) and the associated discomfort produced by each phase duration was measured. RESULTS: In part 1 of the study, we found that the average MEITs generated with each phase duration (400, 700, and 1000 µs) were 55.0, 56.3, and 58.0% of MVIC respectively, but the differences were not statistically significant (p=.45). In part 2, we found a statistically significant increase in discomfort over the same range of phase durations. The results indicate that, for a given level of torque production, discomfort increases with increasing phase duration (p=.008). CONCLUSIONS: Greater muscle torque cannot be produced by increasing the stimulus phase duration over the range examined. Greater discomfort is produced by increasing the stimulus phase duration. .

Levantamento qualitativo de gêneros de parasitos em amostras fecais de jacarés criados comercialmente em sistema fechado no estado do Rio de Janeiro / Qualitative survey of parasites genera on fecal samples of alligators in a commercial closed farming system in the state of Rio de Janeiro

O objetivo desta pesquisa foi realizar um diagnóstico qualitativo dos gêneros de parasitos encontrados em amostras fecais ambientais de jacarés (Caiman latirostris Daudin, 1802), criados comercialmente em sistema fechado, no período de 2008 a 2009, no estado do Rio de Janeiro. Um total de 300 amostras foi coletado de 150 filhotes, 80 de animais de engorda e 70 de reprodução, e submetido a análises coproparasitológicas, de flutuação (método de Willis-Mollay) e sedimentação simples (método de Lutz), de acordo com Hoffmann (1987). As amostras foram visualizadas à luz da microscopia óptica. Os resultados obtidos evidenciaram a presença de oocistos de Eimeria e Isospora, cistos de Balantidium e ovos de Acanthostomum e Dujardinascaris.

The objective of this paper was to diagnose qualitatively parasite genera found in environmental fecal samples of alligators (Caiman latirostris Daudin, 1802) commercially bred from 2008 to 2009 in a closed farming system in the state of Rio de Janeiro. A total of 300 samples were collected from 150 young, 80 fattening and 70 breeding processed by two different methods, the flotation (method of Willis-Mollay) and simple sedimentation (method of Lutz), according to Hoffmann (1987). The samples were then examined by optical microscopy. The results revealed presence of Eimeria and Isospora oocysts, Balantidium cysts, and Acanthostomum and Dujardinascaris eggs.

Diel use of a saltwater creek by white-tip reef sharks Triaenodon obesus (Carcharhiniformes: Carcharhinidae) in Academy Bay, Galapagos Islands

White-tip reef sharks are common inhabitants of the shallow waters surrounding the Galapagos Islands, where several known aggregation sites have become touristic attractions. With the aim to describe site fidelity and residency patterns of the white-tip reef sharks in a saltwater creek, we used the ultrasonic telemetry method. The study was undertaken in a saltwater channel South of Academy Bay, Santa Cruz Island, from May 2008-September 2009. A total of nine transmitters were attached to sharks and ultrasonic receivers were deployed at the inner and outside areas of the creek. From the total of fitted sharks, four lost their transmitters. The results obtained with the remaining sharks showed an elevated use of the inner area of the channel during the day, with more use of the external area during the night. However, none of the sharks were detected at the site every day, suggesting that they may have a number of preferred sites within their home range. More studies are needed to detail the home range and habitat use of this species, and to guide its protection level in the AcademyBay area. Rev. Biol. Trop. 60 (2): 735-743. Epub 2012 June 01.

Los tiburones punta blanca de arrecife son habitantes comunes de las aguas que rodean las Islas Galápagos, por lo que muchos de sus sitios de agregación se han convertido en atractivos turísticos. Con el objetivo de describir la fidelidad del sitio y los patrones de residencia de nueve tiburones desde mayo 2008-septiembre 2009, se utilizó telemetría ultrasónica en un canal de agua salada en el sur de Bahía Academia, Isla Santa Cruz. A pesar de que cuatro tiburones perdieron sus transmisores, los restantes tiburones monitoreados mostraron un uso elevado del interior del canal durante el día y del exterior durante la noche. Sin embargo, ninguno de los tiburones fue detectado en el sitio diariamente, lo cual sugiere que deben tener un número mayor de sitios preferidos dentro de su área de vida.

Diabetes self-care activities: A community-based survey in urban southern India.

Background. Diabetes is a lifestyle disease and can be successfully managed by good self-care activities such as diet, exercise, monitoring and drug adherence. Adequate baseline information about the prevalence of good self-care activities is not available from India. We aimed to estimate the existing self-care behaviours and factors influencing these behaviours among adult patients with type 2 diabetes in urban southern India. Methods. A cross-sectional survey was conducted using a cluster design in an urban community in southern India. The Summary Diabetes Self-Care Activities questionnaire was used to collect information on diet, exercise, monitoring of blood sugars and adherence to drugs. Risk factors such as marital status, socioeconomic status, depression, benefit-finding and duration of illness, which are likely to influence self-care behaviour, were assessed. Results. Good dietary behaviour was present in 29% (95% CI 20.8%–37.2%), good exercise behaviour in 19.5% (95% CI 17.4%–21.6%), regular blood sugar monitoring in 70% (95% CI 62.2%–77.8%) and drug adherence in 79.8% (95% CI 75.1%–84.5%). Being male (OR 3.38; 95% CI 1.541–7.407) and married (OR 5.60; 95% CI 1.242–25.212) significantly favoured good exercise behaviour. Being married (OR 2.322; 95% CI 1.104– 4.883) and belonging to the higher socioeconomic status (OR 2.713; 95% CI 1.419–5.190) were significantly associated with monitoring of blood sugars. Conclusions. Self-care activities with respect to diet and exercise are poor in the population studied. The self-care activities relating to blood sugar monitoring and drug adherence are good. Improving self-care behaviour among patients with diabetes in India should start with adequate targeted health education.

Estrogen deficiency reversibly induces telomere shortening in mouse granulosa cells and ovarian aging in vivo

Estrogen is implicated as playing an important role in aging and tumorigenesis of estrogen responsive tissues; however the mechanisms underlying the mitogenic actions of estrogen are not fully understood. Here we report that estrogen deficiency in mice caused by targeted disruption of the aromatase gene results in a significant inhibition of telomerase maintenance of telomeres in mouse ovaries in a tissue-specific manner. The inhibition entails a significant shortening of telomeres and compromised proliferation in the follicular granulosa cell compartment of ovary. Gene expression analysis showed decreased levels of proto-oncogene c-Myc and the telomerase catalytic subunit, telomerase reverse transcriptase (TERT), in response to estrogen deficiency. Estrogen replacement therapy led to increases in TERT gene expression, telomerase activity, telomere length and ovarian tissue growth, thereby reinstating ovary development to normal in four weeks. Our data demonstrate for the first time that telomere maintenance is the primary mechanism mediating the mitogenic effect of estrogen on ovarian granulosa cell proliferation by upregulating the genes of c-Myc and TERT in vivo. Estrogen deficiency or over-activity may cause ovarian tissue aging or tumorigenesis, respectively, through estrogen regulation of telomere remodeling.

O objetivo do estudo foi caracterizar a formação e a atuação do psicólogo vinculado às unidades básicas de saúde de Natal - RN. Uma entrevista semi-estruturada foi aplicada a 28 profissionais dos 4 distritos sanitários. Os resultados mostram que 93 por cento são do sexo feminino, 46 por cento têm idade entre 30-40 anos, 89 por cento se graduaram na UFRN fazendo estágio em clínica (69 por cento), 89 por cento buscaram estudos pós-graduados, 54 por cento realizaram unicamente psicoterapia e 46 por cento aliada a outras atividades. São discutidas a marcante presença da atividade psicoterapêutica na prática do psicólogo; a desvinculação do trabalho dos princípios do SUS; a dificuldade de ultrapassar as concepções individualistas e psicologizantes dos problemas sociais em virtude da cultura profissional do psicólogo. A não adoção do conceito de saúde que implicaria uma concepção e atenção diferenciadas, equânimes e preventivas, dificulta as ações que diferem do modelo assistencial-curativo, reinante no ordenamento das políticas e na ações de saúde
