Correlation between levels of perceived stress and depressive symptoms in the functional disability of patients with fibromyalgia.

OBJECTIVE: The aim of this study was to evaluate the factors that are most correlated with the levels of functional disability in patients with fibromyalgia. METHODS: This is a cross-sectional descriptive study in which 42 patients diagnosed with fibromyalgia according to the criteria of the American College of Rheumatology reported their status using the following questionnaires: the Beck Depression Inventory, the Perceived Stress Scale 14, the Revised Fibromyalgia Impact Questionnaire, the Visual Analog Pain Scale, and the Health Assessment Questionnaire. RESULTS: Moderate to severe levels of depression (Beck Depression Inventory: 22.35±10.39), moderate to severe functional disability (Health Assessment Questionnaire: 1.28±0.58), and high levels of stress (Perceived Stress Scale 14: 31.59±10.02) were found. The correlation adjusted by multiple regression as a function of the Health Assessment Questionnaire indicated a negligible to weak positive correlation with perceived stress (r=0.11), while a moderately strong positive correlation was observed with the Visual Analog Pain Scale (r=0.55). Regarding physical exercise, one of the pillars of the treatment, a moderate negative correlation was found with the Health Assessment Questionnaire (r=-0.4). CONCLUSION: The pain levels were moderately influenced by depression severity. The factors most linked to functional disability are due to the pain levels but not to the perception of stress.

Adaptation to Brazilian Portuguese and Latin-American Spanish and psychometric properties of the Mental Illness Clinicians' Attitudes Scale (MICA v4).

OBJECTIVE: To describe translation to Spanish and Portuguese and adaptation of the Mental Illness Clinicians' Attitudes Scale version 4 (MICA v4). METHODS: The questionnaire was administered to primary care physicians (PCPs) from four Latin-American countries, Brazil, Bolivia, Chile, and Cuba. The validation process included four phases: 1) translation of the questionnaire to Spanish and Portuguese; 2) assessment of face validity; 3) assessment of reliability; and 4) evaluation of construct validity with confirmatory factor analysis (CFA). RESULTS: The study sample comprised 427 PCPs. The mean age of the Spanish-speaking sample (n = 252) was 40.1 (S.D = 9.7) years and the mean age of the Portuguese-speaking sample (n = 150) was 40.2 (S.D = 10.9) years. Both models demonstrated "appropriate" internal reliability. Total omega was 0.91 for the Spanish-speaking sample and 0.89 for the Portuguese-speaking sample. The CFA of both questionnaires showed an appropriate fit for a three-factor model (Portuguese: CFI = 0.927; TLI = 0.913; RMSEA = 0.066; Spanish: CFI = 0.945; TLI = 0.935; RMSEA = 0.068). CONCLUSION: The Latin-American versions of the MICA v4 in Spanish and Brazilian Portuguese have appropriate psychometric properties, good internal consistency, and are applicable to and acceptable in the Latin-American context. The instrument proved its validity for collecting data on stigmatizing attitudes among health professionals in different contexts and cultures.

Management of common mental disorders should take place in primary health or specialized care? Clinical decisions of psychiatrists from Latin American countries.

OBJECTIVE: The objective of our study was to explore clinical decisions of psychiatrists regarding the management of common mental disorders in primary care (PC) in four Latin Americans countries, through the application of clinical vignettes. METHODS: Using a cross-sectional design, we conducted a self-administered online questionnaire survey of psychiatrists from Bolivia, Brazil, Cuba, and Chile. The questionnaire covered sociodemographic and professional information. The psychiatrists' clinical decisions were assessed through three clinical vignettes representing typical PC cases of depression, anxiety, and somatization. RESULTS: 230 psychiatrists completed the online survey. Psychiatrists from Brazil were less likely to recognize depression as a mental disorder than those from Cuba (odds ratio (OR) = 0.30, 95% confidence interval (CI), 0.10 to 0.91, p < 0.04). Female gender (OR = 0.19, 95% CI, 0.04 to 0.91, p < 0.02) and older age (OR = 0.92, 95% CI, 0.87 to 0.97, p < 0.01) reduced the likelihood of agreement that depression cases should be treated by a Primary Care Physician (PCP). In the somatoform symptoms vignette, longer training duration increased the likelihood of agreement that treatment should be done by a psychiatrist instead of a PCP (OR = 1.19, 95% CI, 1.04 to 1.37, p < 0.01). In the anxiety vignette, females (OR = 2.38, 95% CI, 1.10 to 5.13, p < 0.01) and participants from Bolivia (compared with Cubans, OR = 4.19, 95% CI, 1.22 to 14.42, p < 0.02) were more likely to consider that these patients should be treated by a psychiatrist instead of a PCP. DISCUSSION: Most psychiatrist respondents agreed that patients with depression should be treated by PCPs and that somatoform and anxiety cases should be treated by psychiatrists. These results show that psychiatrists consider that they, and not PCPs, should treat patients with common mental disorders, regardless of the evidence showing that common mental disorders can be treated by primary care physicians in PC.

Neutrophil-to-Lymphocyte Ratio Predicts Cancer Outcome in Locally Advanced Clear Renal Cell Carcinoma.

BACKGROUND: To evaluate the association of neutrophil-to-lymphocyte ratio (NLR) with recurrence-free survival (RFS) and overall survival (OS) in patients with locally advanced nonmetastatic clear cell renal cell carcinoma (ccRCC) undergoing radical nephrectomy. MATERIAL AND METHODS: We retrospectively identified 880 nephrectomies performed between January 2009 and December 2016 in a single center, reviewed data from 478 radical nephrectomies for kidney tumors and identified 187 patients with locally advanced nonmetastatic ccRCC (pT3-T4 N0M0). NLR was obtained preoperatively and calculated by dividing absolute neutrophil count by absolute lymphocyte count. OS and RFS were evaluated by the Kaplan-Meier method. Cox proportional-hazards regression models were used to evaluate predictors of RFS and OS. RESULTS: Among 187 patients with ccRCC (mean age 63.4 ± 11.5 years; 118 [63.1%] male), the median follow-up was 48.7 months. On univariate analysis, in patients with Fuhrman nuclear grade of differentiation 3-4, the median time to recurrence was significantly shorter with NLR ≥ 4 than < 4 (24 vs. 55 months, P = .045). On multivariable analysis adjusted for NLR ≥ 4, among all variables analyzed (NLR, microvascular invasion, sarcomatoid differentiation, tumor size and body mass index), only nuclear grade of differentiation was an independent predictor of recurrence (hazard ratio 2.18; 95% confidence interval 1.07-4.92, P = .03). The 3-year OS had no statistically significant difference between patients with NLR ≥ 4 or < 4. CONCLUSION: For patients with locally advanced, nonmetastatic ccRCC, RFS was reduced with high nuclear grade of differentiation and high preoperative NLR. These findings suggest an association between higher NLR and worse outcomes in locally advanced ccRCC.

Real estate data to analyse the relationship between property prices, sustainability levels and socio-economic indicators.

Recent studies have sought to explore the relationship between environmental and financial performance, in particular the relationship between the energy efficiency level of a building and its financial value. The present real estate dataset contains 43 variables of repeat sales transactions, energy performance certificate (EPC) rating, index of multiple deprivation (IMD), and geographical location of properties in England and Wales involved in a total of 4,201 transactions from 1995 to 2012. This dataset enables researchers and practitioners to further explore important questions regarding the nexus between the real estate industry, sustainability levels, and socio-economic aspects. Due to the scarcity of publicly available quality real estate data, the dataset detailed in this article may play a relevant role by becoming easily discoverable, clearly explained, and structured to be ready to be used by researchers, analysts, and policymakers. The empirical analysis of the economic case for energy-efficient dwellings in the UK private rental market performed in Fuerst, et al. [1] is based on this dataset.

Sphere-sphere intersection for investment portfolio diversification - A new data-driven cluster analysis.

Aiming at supporting the process of investment portfolio diversification by using a data-driven approach, the present methodological paper proposes a new cluster analysis, which compares publicly traded companies, mainly in times of high volatility (e.g. crisis times). The main goal of the proposed method is to provide a less arbitrary analysis to support financial investors to precisely measure the degree of similarity between equity stocks, unveiling equity market clustering patterns by applying analytic geometry solutions and calculating an overall clustering pattern indicator. Empirical results on synthetic data demonstrate either that the proposed method has conceptual superiority over traditional cluster analyses and its potential practical usefulness to asset allocation, portfolio strategy, asset pricing, among other related purposes. Finally, the outputs of the proposed cluster analysis are presented through an intuitive and easily understandable mathematical visualization. •It is proposed a new method to calculate risk-similarity and clustering patterns.•The method unveils clustering patterns through a data-driven process.•Portfolio diversification can benefit from sphere-sphere intersection calculations.

Skin manifestations of tick bites in humans.

Ticks are blood-sucking arthropods that attach to human skin through oral devices causing diverse initial cutaneous manifestations, and may also transmit serious infectious diseases. In certain situations, the Health Teams (and especially dermatologists) may face difficulties in identifying the lesions and associating them to the parasites. To assist them in clinical diagnosis, we suggest a classification of the skin manifestations in primary lesions, which occur by the attachment the tick to the host (for toxicity and the anticoagulant substances in the saliva and/or marked inflammation by the penetration and permanence of the mouthparts) and secondary lesions that are manifestations of infections caused by rickettsia, bacteria, protozoa and fungi inoculated by the ticks.

Building Connections With Patients and Families in the Intensive Care Unit: A Canadian Top-Performer Success Story.

Consumers are increasingly becoming the voice and impetus for hospital organizational change in the United States. This is in part due to their increased stake in cost sharing with hospitals, health systems, and the ambulatory setting and revisions to health plans with higher deductibles and copays. With customers wanting services better, faster, and more economical than in the past, organizations need to break the ceiling on improvement levels for exceeding expectations of patient experience. Of interest is the hospital critical care area, because of the heightened patient needs, support, and resources that are required in this acute setting. Bluewater Health, located in Sarnia, Ontario, Canada, is a top-industry performer on the patient experience access-to-care dimension. Much can be learned from the multiple practices it has used to create an environment that embraces patients and families to the fullest extent, ensuring the resources needed for optimizing care are received.

Inhibition of Epithelial-mesenchymal Transition in Response to Treatment with Metformin and Y27632 in Breast Cancer Cell Lines.

BACKGROUND: ROCK-1 expression is associated with the malignant character of tumors, while inhibiting this molecule results in a significant suppression of tumor metastasis. Likewise, transforming growth factor beta (TGF-ß) is associated with this malignancy by having the ability to induce epithelial-mesenchymal transition (EMT). Metformin, a drug used in the treatment of diabetes, has previously been shown to inhibit EMT in breast cancer cells. OBJECTIVE: The aim of this study is to evaluate the TGF-ß1 action model for induction of EMT and the action of metformin and ROCK-1 inhibitor (Y27632) in EMT process in breast cancer cell lines. METHOD: MCF-7 and MDA-MB-231 cell lines were treated with metformin and Y27632, after induction of EMT by TGF-ß1, to examine the effects on cell migration as well as the protein expression of the ROCK-1 markers, vimentin, E-cadherin, CD44 and CD24 by immunocitochemistry. RESULTS: There was a lower protein expression of ROCK-1, vimentin, CD44 and CD24 in both cell lines after treatment with metformin and Y27632. In MDA-MB-231 cells, E-cadherin expression was increased in all treatment groups. Treatment of MDA-MB-231 cell line with metformin and Y27632 significantly reduced the invasion of these cells. CONCLUSION: This study confirms the benefits of metformin and Y27632 as potential therapeutic agents in mammary tumors, by blocking EMT process and metastatic potential.

Patient with a Starr-Edwards prosthesis in the aortic position for 40 years.

Herein is reported the case of a patient who presented initially with aortic insufficiency and a fistula between the sinus of Valsalva and right atrium when aged 31 years. Closure of the fistula and replacement of the aortic valve with a Starr-Edwards A-9 caged-ball prosthesis was performed in 1972, since when the valve has survived for 40 years without dysfunction. This is one of the longest follow ups of the Starr-Edwards prosthesis reported, and highlights the possibility of acceptable valve performance over long periods of time.

Compliance with surgical care improvement project blood glucose--a marker for euglycemia, but does it put our patients at risk?

To improve outcomes in open heart surgery (OHS) patients, the Surgical Care Improvement Project (SCIP) requires 6 am postoperative day (POD) 1 and 2 blood glucose (BG) to be ≤200mg/dL. This study examined risk factors for SCIP noncompliance when using an insulin infusion protocol (IIP) and evaluated this SCIP metric as a surrogate for glycemic control. The authors divided 99 consecutive OHS patients, all subjected to 1 uniform IIP, into 2 groups: Group 1-SCIP compliant (n=79) and Group 2-SCIP noncompliant (n=20). They determined mean BG for the first 48 postoperative hours, percent of total time with hyperglycemia (% time BG >200mg/dL) for each group, and assessed risk of SCIP noncompliance as relates to multiple risk factors including intensity of IIP application, and switching to subcutaneous (SQ) insulin prior to 6 am on POD 2. Group 1 had lower mean BG than Group 2 and percent of total time with hyperglycemia, P<0.0001. Multivariate analysis showed diabetes, obesity in nondiabetics, and switching to SQ insulin prior to 6 am on POD 2 to be risk factors for SCIP noncompliance. The 6 am BG values on POD 1 or POD 2 each correlated with average postoperative BG, and compliance with the SCIP BG metric was associated with virtually uniform BG ≤200mg/dL. IIP application was not significantly different between groups (P=0.2). Only patients who had been switched to SQ insulin prior to 6 am POD 2 were noncompliant at 6 am on POD 2. There were hypoglycemic events (BG <70mg/dL) in 15 of 99 patients (15%), 12 of whom (80%) were in Group 1. Noncompliance with this SCIP measure occurred more frequently in patients with diabetes or, if nondiabetic, in those patients with obesity. A trend toward increased insulin assessments in the SCIP noncompliant group suggests that 1 uniform IIP for all patients may not be effective. By not requiring the reporting of hypoglycemia, SCIP may inadvertently be exposing patients to harm.

Manifestação rara de edema agudo de pulmão associado à miocardite lúpica aguda - relato de caso / Unusual clinical manifestation of acute pulmonary edema associated to acute lupic myocarditis - case report

O lupus eritematoso sistêmico (LES) é a mais comum das doenças auto-imunes sistêmicas. Embora os rins classicamente sejam os órgãos mais acometidos no LES, o coração também pode ser afetado de forma significativa. Entretanto, a ocorrência de edema agudo de pulmão associado à miocardite lúpica é rara e de tratamento imunossupressor específico ainda incerto. O presente relato de caso revisa a literatura quanto a manifestações lúpicas do sistema cardiopulmonar, seu diagnóstico e tratamento, e descreve uma paciente lúpica jovem que evoluiu com edema agudo de pulmão decorrente de uma miopericardite lúpica aguda. O rápido diagnóstico pôde permitir o emprego da terapêutica imunossupressora adequada com reversão completa da disfunção miocárdica. Em pacientes jovens com quadro sugestivo de edema agudo de pulmão, o diagnóstico de LES deve ser considerado. O uso de pulsoterapia com corticóide endovenoso mostrou-se eficaz e seguro para o tratamento da manifestação cardíaca extrema.

Systemic lupus erythematosus is the most common systemic autoimmune disease. Although kidneys are the mainorgans affected, heart may suffer injury too. However, acute pulmonary edema associated to lupic myocarditis is rare and its specific immunosuppressive treatment is still undefined. The present case report reviews literature about lupic manifestations in heart and lungs, their diagnosis and treatment, and describes an young lupic patient that had pulmonary edema due toacute lupic myopericarditis. Prompt diagnosis enabled correct immunosuppressive therapy that resulted in a complete reversion of myocardial disfunction. Lupus is a possible diagnosis in young patients with pulmonary edema. The use of intravenous pulse therapy with corticosteroids was safe and efficient to healing of this severe myocardial manifestation.

Artrite reumatóide e doença cardiovascular na atualidade: o que sabemos sobre essa associação e o que podemos fazer pelo paciente? / Rheumatoid arthritis and cardiovascular disease: what do we know about this relationship and how can we treat affected patients nowadays?

O interesse em doenças auto-imunes vem crescendo a cada ano, principalmente sobre sua relação com doenças cardiovasculares. Especificamente a artrite reumatóide vem sendo considerada um fator de risco independente para doença arterial coronária nos últimos anos. Diversos estudos foram realizados recentemente com o objetivo de esclarecer pontos cruciais na estratificação de risco desses pacientes e no seu respectivo tratamento medicamentoso adequado. Novas terapias específicas da doença reumatóide ainda estão em estudo, e prometem reduzir o risco cardiovascular a longo prazo. Desse modo, realizamos uma revisão bibliográfica ampla, utilizando as principais bases de dados nacionais e internacionais, com o objetivo de salientar a importância de mecanismos ateroscleróticos e inflamatórios sobre a doença arterial coronária. Além disso, frente às atuais evidências, sugerimos estratégias de estratificação de risco e tratamento da doença arterial coronária em pacientes com artrite reumatóide.

The interest in auto-immune diseases has been grown, mainly about cardiovascular illnesses. Rheumatoid arthritis has been considered an independent risk factor for coronary arterial disease in last years. Recently, different studies have been performed in order to better clarify crucial points in risk stratification and correct treatment for patients with rheumatoid arthritis. New specific therapies have been studying and promising reduction of cardiovascular risk. Thereby, we made a bibliographic revision to show the importance of atherosclerotic and inflammatory mechanisms in coronary artery disease. Furthermore, wesuggested different strategies to establish risk stratification andtreatment of cardiovascular diseases in patients with rheumatoid arthritis.

[Rheumatoid arthritis and cardiovascular disease: what is known about this relationship and what can currently be done for affected patients?]. / Artrite reumatóide e doença cardiovascular: o que sabemos e o que podemos fazer pelo paciente na atualidade?

There is increasing interest in autoimmune diseases, especially their relationship with cardiovascular disease. Rheumatoid arthritis in particular has been considered an independent risk factor for coronary artery disease in recent years. Various studies have aimed to clarify important aspects of risk stratification and treatment options in patients with rheumatoid arthritis, and specific therapies are being studied that promise to reduce their long-term cardiovascular risk. We performed a wide-ranging review of the literature to highlight the importance of atherosclerotic and inflammatory mechanisms in coronary artery disease. We also suggest strategies for risk stratification and treatment of cardiovascular disease in patients with rheumatoid arthritis.
