Exercise induction of gut microbiota modifications in obese, non-obese and hypertensive rats

Background: Obesity is a multifactor disease associated with cardiovascular disorders such as hypertension. Recently, gut microbiota was linked to obesity pathogenesisand shown to influence the host metabolism. Moreover, several factors such as host-genotype and life-style have been shown to modulate gut microbiota composition. Exercise is a well-known agent used for the treatment of numerous pathologies, such as obesity and hypertension; it has recently been demonstrated to shape gut microbiota consortia. Since exercise-altered microbiota could possibly improve the treatment of diseases related to dysfunctional microbiota, this study aimed to examine the effect of controlled exercise training on gut microbial composition in Obese rats (n = 3), non-obese Wistar rats (n = 3) and Spontaneously Hypertensive rats (n = 3). Pyrosequencing of 16S rRNA genes from fecal samples collected before and after exercise training was used for this purpose. Results: Exercise altered the composition and diversity of gut bacteria at genus level in all rat lineages. Allobaculum (Hypertensive rats), Pseudomonas and Lactobacillus (Obese rats) were shown to be enriched after exercise, while Streptococcus (Wistar rats), Aggregatibacter and Sutturella (Hypertensive rats) were more enhanced before exercise. A significant correlation was seen in the Clostridiaceae and Bacteroidaceae families and Oscillospira and Ruminococcus genera with blood lactate accumulation. Moreover, Wistar and Hypertensive rats were shown to share a similar microbiota composition, as opposed to Obese rats. Finally, Streptococcus alactolyticus, Bifidobacterium animalis, Ruminococcus gnavus, Aggregatibacter pneumotropica and Bifidobacterium pseudolongum were enriched in Obese rats. Conclusions: These data indicate that non-obese and hypertensive rats harbor a different gut microbiota from obese rats and that exercise training alters gut microbiota from an obese and hypertensive genotype background

Femoral anteversion and the neck-shaft angle: relationship with hip osteoarthritis

OBJECTIVE: To compare the existence of agreement between measurements of anteversion of the femoral neck and the degrees of osteoarthritis and abnormality of the neck-shaft angle in patients with unilateral idiopathic hip osteoarthritis, among three evaluators. METHODS: Forty- two patients with unilateral hip osteoarthritis were evaluated by means of simple radiography and computed tomography. RESULTS: It was observed that there was no significant variation in femoral anteversion between the diseased and healthy hips. There was strongest agreement between observers 1 and 2 in relation to both the diseased hips (cases) and the healthy hips (controls). Moreover, no significant agreement was found between observers 1 and 3 (p = 0.13) and between observers 2 and 3 (p = 0.12), in relation to the neck-shaft angle of the control hips. CONCLUSION: Although there was no relationship between femoral anteversion and the neck-shaft angle in the patients with unilateral hip osteoarthritis, the present study showed that there was also no relationship with these angular deviations.OBJETIVO: Comparar, entre três avaliadores, a existência de concordância das medidas da anteversão do colo femoral com o grau da osteoartrite e a alteração do ângulo cervicodiafisário em pacientes com osteoartrite idiopática unilateral do quadril. MÉTODOS: Foram avaliados 42 pacientes com osteoartrite unilateral do quadril por meio de radiografia simples e tomografia computadorizada. RESULTADOS: Observou-se que não ocorreu variação significativa na anteversão femoral entre o quadril doente e o sadio. Houve uma concordância mais forte entre os observadores 1 e 2, tanto em relação ao quadril doente (caso) quanto ao sadio (controle). Além disso, não foi verificada concordância significativa entre os observadores 1 e 3 (p = 0,13) e entre 2 e 3 (p = 0,12) em relação ao ângulo cervicodiafisário do quadril controle. CONCLUSÃO: Apesar de não ter ocorrido relação entre a anteversão femoral e o ângulo cervicodiafisário nos pacientes com osteoartrite unilateral do quadril, este estudo demonstrou não haver relação com estes desvios angulares.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaHospital Santa Teresa Serviço de Ortopedia e TraumatologiaHospital Santa Teresa Serviço de Ortopedia e Traumatologia Grupo de QuadrilUFRJ Faculdade de MedicinaINTOINTO Grupo de Pelve e AcetábuloUNIFESP, EPMSciEL

Ten-year survival of patients undergoing coronary angioplasty with first-generation sirolimus-eluting stents and bare-metal stents

Introduction: Compared to bare-metal stents (BMS), drug-eluting stents reduce stent restenosis and improve subsequent revascularization rates. The impact on patients’ survival has been the subject of debate. Objective: To assess the long-term (10-year) survival of patients undergoing percutaneous coronary intervention (PCI) with first-generation sirolimus-eluting stents (SES) in comparison with BMS. Methods: In a single-center registry, 600 consecutive patients who underwent successful PCI with SES between April 2002 and February 2003 were compared to 594 patients who underwent PCI with BMS between January 2002 and April 2002, just before the introduction of SES. Clinical and procedural data were collected at the time of intervention and 10-year survival status was assessed via the national life status database. Results: All baseline characteristics were similar between groups except for smaller stent diameter (2.84±0.38 vs. 3.19±0.49 mm; p<0.001), greater stent length (18.50±8.2 vs. 15.96±6.10 mm; p<0.001) and higher number of stents per patient (1.95 vs. 1.46, p<0.001) in the SES group. Overall five- and 10-year all-cause mortality was 9.6% (n=110) and 22.7% (n=272), respectively. The adjusted HR for 10-year mortality in patients undergoing PCI with SES was 0.74 (95% CI 0.58-0.94; p=0.013), corresponding to a relative risk reduction of 19.8%. Other than PCI with BMS, older age, chronic kidney disease, chronic obstructive pulmonary disease and lower ejection fraction were independent predictors of 10-year mortality. Conclusion: To date, this is the longest follow-up study ever showing a potential survival benefit of first-generation sirolimus-eluting stents versus bare-metal stents, supporting prior observations on their sustained efficacy and safety relative to contemporary BMS.publishersversionpublishe

Consultas neurológicas e diagnósticos em um grande hospital universitário dedicado a COVID-19

Background: More than one-third of COVID-19 patients present neurological symptomsranging from anosmia to stroke and encephalopathy. Furthermore, pre-existingneurological conditions may require special treatment and may be associated with worseoutcomes. Notwithstanding, the role of neurologists in COVID-19 is probablyunderrecognized. Objective: The aim of this study was to report the reasons forrequesting neurological consultations by internists and intensivists in a COVID-19-dedicated hospital. Methods: This retrospective study was carried out at Hospital dasClínicas da Faculdade de Medicina da Universidade de São Paulo, Brazil, a 900-bedCOVID-19 dedicated center (including 300 intensive care unit beds). COVID-19 diagnosiswas confirmed by SARS-CoV-2-RT-PCR in nasal swabs. All inpatient neurologyconsultations between March 23rd and May 23rd, 2020 were analyzed. Neurologistsperformed the neurological exam, assessed all available data to diagnose theneurological condition, and requested additional tests deemed necessary. Difficultdiagnoses were established in consensus meetings. After diagnosis, neurologists wereinvolved in the treatment. Results: Neurological consultations were requested for 89 outof 1,208 (7.4%) inpatient COVID admissions during that period. Main neurologicaldiagnoses included: encephalopathy (44.4%), stroke (16.7%), previous neurologicaldiseases (9.0%), seizures (9.0%), neuromuscular disorders (5.6%), other acute brainlesions (3.4%), and other mild nonspecific symptoms (11.2%). Conclusions: Mostneurological consultations in a COVID-19-dedicated hospital were requested for severeconditions that could have an impact on the outcome. First-line doctors should be able torecognize neurological symptoms; neurologists are important members of the medicalteam in COVID-19 hospital care.Introdução: Mais de um terço dos pacientes com COVID-19 apresentam sintomasneurológicos que variam de anosmia a AVC e encefalopatia.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Generalidades sobre o quadro clínico da Rinossinusite: uma revisão narrativa de literatura: Generalities about the clinical picture of Rhinosinusitis: a narrative literature reviewv

A rinossinusite é um processo inflamatório da mucosa dos seios paranasais e da cavidade nasal. O sistema nasossinusal é responsável pelo balanço adequado entre a fabricação e o clearence de muco nas cavidades paranasais. A fisiologia deste é de vital importância para a proteção das vias aéreas superiores. No advém, determinados fatores podem acarretar um desbalanço nesse complexo, consequentemente um processo inflamatório. Qualquer fator que altere a drenagem, seja por obstrução, maior produção ou espessamento do muco, como processo infecciosos ou alérgicos, haverá uma impactação de secreções e a facilitação de colonização bacteriana, dando início ao processo infeccioso. A identificação da inflamação do nariz e seios paranasais é basicamente clínica. A suspeição desta ocorre através da manifestação de dois ou mais sintomatologias. As quais são o bloqueio ou obstrução nasal, a descarga nasal, pressão ou dor facial e redução ou perda do olfato. De modo geral, é essencial à prevenção básica das rinossinusites agudas é barrar a infecção viral. O suporte inclui medidas gerais de higiene, alimentação e hidratação, imunização para o combate de vírus respiratórios , administração de fármacos para turbinar o sistema imune se necessário
