Greater perceived stress management skills and heightened brain metabolic activity in cortical and subcortical stress processing regions in metastatic breast cancer patients.

PURPOSE: Emotional distress and adversity can contribute to negative health outcomes in women with breast cancer. Individual differences in perceived stress management skills such as cognitive reframing and relaxation for coping with adversity have been shown to predict less distress and better psychological and physiological adaptation. Prior work shows that more distressed breast cancer patients reveal less metabolic activity in brain regions such as the insula, thalamus, ventromedial and lateral prefrontal cortices. This led us to pose the hypothesis that breast cancer patients with greater stress management skills (e.g., ability to reframe stressors and use relaxation) may conversely show greater activation in these brain regions and thereby identify brain activity that may be modifiable through stress management interventions. The main objective of this study was to examine the association of perceived stress management skill efficacy with the metabolism of 9 key stress-implicated brain regions in women diagnosed with metastatic breast cancer. METHODS: Sixty women (mean age 59.86 ± 10.04) with a diagnosis of mBC underwent 18F-fluorodeoxyglucose positron emission tomography. Perceived stress management skill efficacy was assessed with the Measure of Current Status Scale. RESULTS: Greater perceived stress management skill efficacy related significantly to higher metabolic activity in the insula, thalamus, ventromedial and lateral prefrontal cortices, and basal ganglia; this network of regions overlaps with those previously shown to be under-activated with greater level of distress in this same sample of metastatic breast cancer patients. CONCLUSION: This is the first study to demonstrate in metastatic cancer patients that greater perceptions of stress management skill efficacy are associated with metabolic activity in key brain regions and paves the way for future studies tracking neural mechanisms sensitive to change following stress management interventions for this population.

Global research trends related to coronavirus disease 2019 and the aged: a bibliometric analysis

ABSTRACT BACKGROUND: A bibliometric analysis covering only the production of original studies or considering world production until 2022 has yet to be conducted. The creation and advancement of vaccines have also influenced research priorities, demonstrating the need for a new approach to this subject. OBJECTIVES: To analyze worldwide scientific production related to coronavirus disease 2019 (COVID-19) and the aged and to describe what has already been produced. DESIGN AND SETTING: Bibliometric analysis with a quantitative approach. METHOD: The search terms "COVID-19," "SARS-CoV-2," "Aged," and "Elderly" were used to retrieve articles from the Web of Science database. A total of 684 articles were included in the analysis. Data were imported into RStudio Desktop Software and linked to R Software. The Bibliometrix R package and VOSviewer software were used for analysis. RESULTS: Most articles were published in 2020. These were produced by 4,937 authors and published in 379 journals. The keyword most used by the authors was "COVID-19." Publications from 77 countries were obtained. China had the highest article production ranking, and Spain collaborated the most. The articles addressed the implications of the pandemic on the aged, the relationship between vaccination in the aged, and the implications for the disease itself. CONCLUSION: Further research should be conducted, mainly concerning vaccines and vaccination of the aged, owing to the need for and importance of immunization in this risk group, including assessing the long-term effects of vaccines.

The importance of inflammatory biomarkers in non-specific acute and chronic low back pain: a systematic review.

OBJECTIVE: The purpose of this study was to systematically review the evidence on inflammatory biomarkers as analytic predictors of non-specific low back pain (NsLBP). Low back pain (LBP) is the number one cause of disability globally, posing a major health problem that causes an enormous social and economic burden, and there is an increasing interest on the importance of biomarkers in quantifying and even emerge as potential therapeutic tools to LBP. METHODS: A systematic search was conducted on July 2022 in Cochrane Library, MEDLINE and Web of Science for all the available literature. Cross-sectional, longitudinal cohort or case-control studies that evaluated the relationship between inflammatory biomarkers collected from blood samples and low back pain in humans were considered eligible for inclusion, as well as prospective and retrospective studies. RESULTS: The systematic database search resulted in a total of 4016 records, of which 15 articles were included for synthesis. Sample size comprised a total of 14,555 patients with LBP (acute LBP (n = 2073); chronic LBP (n = 12482)) and 494 controls. Most studies found a positive correlation between classic pro-inflammatory biomarkers and NsLBP, namely C-reactive protein (CRP), interleukin 1 (IL-1) and IL-1ß, interleukin 6 (IL-6) and tumour necrosis factor α (TNF-α). On the other hand, anti-inflammatory biomarker interleukin 10 (IL-10) demonstrated a negative association with NsLBP. Four studies have made direct comparisons between ALBP and CLBP groups regarding their inflammatory biomarkers profile. CONCLUSIONS: This systematic review found evidence of increased levels of pro-inflammatory biomarkers CRP, IL-6 and TNF-α and decreased levels of anti-inflammatory biomarker IL-10 in patients with LBP. Hs-CRP was not correlated with LBP. There is insufficient evidence to associate these findings with the degree of pain severity or the activity status of the lumbar pain over time.

Digital Guardian Angel Supported by an Artificial Intelligence System to Improve Quality of Life, Well-being, and Health Outcomes of Patients With Cancer (ONCORELIEF): Protocol for a Single Arm Prospective Multicenter Pilot Study.

BACKGROUND: According to Europe's Beating Cancer Plan, the number of cancer survivors is growing every year and is now estimated at over 12 million in Europe. A main objective of the European Commission is to ensure that cancer survivors can enjoy a high quality of life, underlining the role of digital technology and eHealth apps and tools to achieve this. OBJECTIVE: The main objective of this study is the development of a user-centered artificial intelligence system to facilitate the input and integration of patient-related biopsychosocial data to improve posttreatment quality of life, well-being, and health outcomes and examine the feasibility of this digitally assisted workflow in a real-life setting in patients with colorectal cancer and acute myeloid leukemia. METHODS: A total of 60 patients with colorectal cancer and 30 patients with acute myeloid leukemia will be recruited from 2 clinical centers: Universitätsmedizin der Johannes Gutenberg-Universität Mainz (Mainz, Germany) and IRCCS Istituto Romagnolo per lo Studio dei Tumori "Dino Amadori" (IRST, Italy). Psychosocial data (eg, emotional distress, fatigue, quality of life, subjective well-being, sleep problems, and appetite loss) will be collected by questionnaires via a smartphone app, and physiological data (eg, heart rate, skin temperature, and movement through step count) will be collected by a customizable smart wrist-worn sensor device. Each patient will be assessed every 2 weeks over their 3-month participation in the ONCORELIEF study. Inclusion criteria include patients with the diagnosis of acute myeloid leukemia or colorectal cancer, adult patients aged 18 years and older, life expectancy greater than 12 months, Eastern Cooperative Oncology Group performance status ≤2, and patients who have a smartphone and agree to use it for the purpose of the study. Exclusion criteria include patients with a reduced cognitive function (such as dementia) or technological illiteracy and other known active malignant neoplastic diseases (patients with a medical history of treated neoplastic disease are included). RESULTS: The pilot study started on September 1, 2022. As of January 2023, we enrolled 33 patients with colorectal cancer and 7 patients with acute myeloid leukemia. As of January 2023, we have not yet started the data analysis. We expect to get all data in June 2023 and expect the results to be published in the second semester of 2023. CONCLUSIONS: Web-based and mobile apps use methods from mathematical decision support and artificial intelligence through a closed-loop workflow that connects health professionals and patients. The ONCORELIEF system has the potential of continuously identifying, collecting, and processing data from diverse patient dimensions to offer health care recommendations, support patients with cancer to address their unmet needs, and optimize survivorship care.

Low social and family well-being is associated with greater RAGE ligand s100A8/A9 and interleukin-1 beta levels in metastatic breast cancer patients.

Greater inflammatory signaling has been shown to promote breast cancer disease progression and poorer clinical outcomes. Lower social support and social well-being have been related to greater inflammatory signaling and poorer clinical outcomes in women with non-metastatic breast cancer, and this appears to be independent of depression. However, little is known about these associations in women with metastatic disease. s100A8/A9 and interleukin 1 beta (IL-1ß) proteins are widely studied in breast cancer and are considered as biomarkers of cancer progression or as having a causal role in carcinogenesis and cancer progression and metastasis via inflammatory signaling. The aim of this study was to examine the associations between less social/family well-being (SWB) and S100A8/A9 and IL-1ß levels in women diagnosed with metastatic breast cancer. Sixty women (Mean age 58.95 â€‹± â€‹1.49) with a diagnosis of metastatic breast cancer participated in the study. The Functional Assessment of Cancer Therapy (FACT) social and family well-being (SWB) subscale and the Hospital Anxiety Depression Scale (HADS) were administered to patients undergoing a first- or second-line endocrine or oral chemotherapy treatment and who were not experiencing brain metastasis or visceral crisis. Salivary s100A8/A9 and IL-1ß levels were assessed at 5PM on two consecutive days and averaged. Multiple regression tested the independent contribution of SWB on s100 A8/A9 and IL-1b while controlling for depression. Lower levels of SWB were associated with greater S100A8/A9 (ߠ​= â€‹-0.345, p â€‹= â€‹0.007) and IL-1ß (ߠ​= â€‹-0.286, p â€‹= â€‹0.027) levels and these associations remained significant after controlling for depression. This work provides new evidence for the role of decreased SWB and greater s100A8/A9 and IL-1b levels in patients diagnosed with metastatic breast cancer. Psychosocial interventions that promote social support and positive social interactions through interpersonal skills may help metastatic breast cancer patients to improve their SWB. This may have salutary effects on cancer-promoting processes, which could provide psychological and physical health benefits.

PD-L1 tumor expression is associated with poor prognosis and systemic immunosuppression in glioblastoma.

PURPOSE: Glioblastoma is the most common primary malignant brain tumor in the adult, whose grim prognosis largely relates to the absence of effective treatment targets. Given its success in other cancers, immunotherapy has been trialed in glioblastoma and failed to demonstrate the expected benefit. Importantly, these disappointing results highlight the importance of understanding the unique and transforming biology of glioblastoma and its microenvironment. Our goal was to evaluate and characterize the expression of PD-L1 through immunohistochemistry in a large glioblastoma cohort. We further studied PD-L1 expression-associated prognosis and its correlation to systemic and neuropathological parameters. METHODS: A series of 352 glioblastoma specimens (313 initial resection, 39 matched recurrences) was collected, with a detailed characterization of tumor neuropathological characteristics, including the presence, density and location of tumor infiltrating lymphocytes (TIL). Two hematological markers, absolute lymphocyte count and neutrophil-lymphocyte ratio (NLR), were used to analyze and correlate with systemic inflammation and immunosuppression. Immunohistochemistry was performed to evaluate PD-L1 expression. RESULTS: Membranous PD-L1 expression was identified in 31% (98/313) of newly diagnosed and 46% (18/39) of matched recurrent tumors. TIL were found in 26% (82/313) of primary tumors and both density and location were found to be significantly associated with PD-L1 expression (p < 0.001). Interestingly, PD-L1 expressing tumors had more frequently areas with sarcomatous differentiation (p < 0.001) and were significantly associated with lower lymphocyte count (p = 0.018) and higher NLR ratio (p = 0.004) upon diagnosis. Importantly, PD-L1 expression was an independent poor prognostic marker in our cohort. CONCLUSION: Taken together, our data points to a putative role for PD-L1 expression in glioblastoma biology, which correlates to poor patient overall survival, as well as with a general systemic inflammatory status and immunosuppression.

Colonization of methicillin-resistant Staphylococcus aureus among healthcare students: an integrative review

ABSTRACT BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) infection is a worldwide concern given its presence even in non-hospitalized healthy individuals, such as university students. OBJECTIVE: To identify in the literature the prevalence of colonization by MRSA among healthcare students. DESIGN AND SETTING: Integrative review of the literature conducted in Universidade Federal do Piauí. METHOD: A search for primary studies was performed in the following databases: Medical Literature Analysis and Retrieval System on-line; Cumulative Index to Nursing and Allied Health Literature; Web of Science; Scopus; and LILACS. RESULTS: This review included 27 studies that demonstrated MRSA infection prevalence ranging from 0.0 to 15.3% among students. CONCLUSION: The prevalence of colonization of MRSA among healthcare students is high, and the nasal cavity was cited as an important reservoir location for these microorganisms.

Cadherin Expression and EMT: A Focus on Gliomas.

Cadherins are calcium-binding proteins with a pivotal role in cell adhesion and tissue homeostasis. The cadherin-dependent mechanisms of cell adhesion and migration are exploited by cancer cells, contributing to tumor invasiveness and dissemination. In particular, cadherin switch is a hallmark of epithelial to mesenchymal transition, a complex development process vastly described in the progression of most epithelial cancers. This is characterized by drastic changes in cell polarity, adhesion, and motility, which lead from an E-cadherin positive differentiated epithelial state into a dedifferentiated mesenchymal-like state, prone to metastization and defined by N-cadherin expression. Although vastly explored in epithelial cancers, how these mechanisms contribute to the pathogenesis of other non-epithelial tumor types is poorly understood. Herein, the current knowledge on cadherin expression in normal development in parallel to tumor pathogenesis is reviewed, focusing on epithelial to mesenchymal transition. Emphasis is taken in the unascertained cadherin expression in CNS tumors, particularly in gliomas, where the potential contribution of an epithelial-to-mesenchymal-like process to glioma genesis and how this may be associated with changes in cadherin expression is discussed.

Negative affect and stress-related brain metabolism in patients with metastatic breast cancer.

BACKGROUND: Cancer and its treatment represent major stressors requiring that patients make multiple adaptations. Despite evidence that poor adaptation to stressors is associated with more distress and negative affect (NA), neuroimmune dysregulation and poorer health outcomes, current understanding is very limited of how NA covaries with central nervous system changes to account for these associations. METHODS: NA was correlated with brain metabolic activity using 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) in several regions of interest in 61 women with metastatic breast cancer. Patients underwent 18 F-FDG PET/CT and completed an assessment of NA using the Brief Symptom Inventory. RESULTS: Regression analyses revealed that NA was significantly negatively correlated with the standardized uptake value ratio of the insula, thalamus, hypothalamus, ventromedial prefrontal cortex, and lateral prefrontal cortex. Voxel-wise correlation analyses within these 5 regions of interest demonstrated high left-right symmetry and the highest NA correlations with the anterior insula, thalamus (medial and ventral portion), lateral prefrontal cortex (right Brodmann area 9 [BA9], left BA45, and right and left BA10 and BA8), and ventromedial prefrontal cortex (bilateral BA11). CONCLUSIONS: The regions of interest most strongly negatively associated with NA represent key areas for successful adaptation to stressors and may be particularly relevant in patients with metastatic breast cancer who are dealing with multiple challenges of cancer and its treatment.

COVID-19 e os animais domésticos: há alguma evidência de relação entre eles? / COVID-19 and the domestic animals: are there some evidence relationship between them?

Objetivo: esta revisão buscou informar, por meio da literatura, pesquisas que abordassem a relação entre COVID-19 e os animais domésticos. Métodos: foram selecionados 29 trabalhos nas diferentes bases de dados, datados de 2003 a 2020, e os descritores utilizados foram: "coronavirus animals", "SARS-Cov-2 animals", "SARS-Cov-2 canine", "SARS-Cov-2 feline". Resultados: poucos trabalhos já foram realizados em animais com o objetivo de comprovar se eles podem se infectar com SARS-Cov-2 e transmitir a doença para outros animais e humanos. Os animais que já foram testados positivos com a COVID-19 não apresentaram sinais clínicos da doença, com exceção de alguns felinos, e, possivelmente, contaminaram-se por meio de humanos infectados. Conclusão: No momento, há alguns questionamentos sobre a possibilidade de transmissão humano-animal, não havendo, ainda, nenhuma informação científica comprovada de que cães e gatos sejam importantes transmissores na cadeia epidemiológica da COVID-19, sendo necessários mais estudos e o monitoramento contínuo de animais de estimação.

Objective: This review sought to inform, through the literature, research that addressed the relationship between COVID-19 and domestic animals. Methods: Twenty-nine works were selected in the different databases, dating from 2003 to 2020 and the descriptors used were: "coronavirus animals", "SARS-Cov-2 animals", "SARS-Cov-2 canine", "SARS-Cov-2 feline". Results: Few studies have been carried out on animals with the aim of proving whether they can become infected with SARS-Cov-2 and transmit the disease to other animals and humans. The animals that have already been tested positive with COVID-19 did not show clinical signs of the disease, except for a few felines, and possibly contaminated by infected humans. Conclusion: At the moment, there are some questions about the possibility of human-animal transmission, and there is still no proven scientific information that dogs and cats are important transmitters in the epidemiological chain of COVID-19, and further studies and ongoing monitoring of pets are required.

Emotional distress, brain functioning, and biobehavioral processes in cancer patients: a neuroimaging review and future directions.

Despite emerging evidence that distress and adversity can contribute to negative health outcomes in cancer, little is known about the brain networks, regions, or circuits that can contribute to individual differences in affect/distress states and health outcomes in treated cancer patients. To understand the state-of-the-science in this regard, we reviewed neuroimaging studies with cancer patients that examined the associations between negative affect (distress) and changes in the metabolism or structure of brain regions. Cancer patients showed changes in function and/or structure of key brain regions such as the prefrontal cortex, thalamus, amygdala, hippocampus, cingulate cortex (mainly subgenual area), hypothalamus, basal ganglia (striatum and caudate), and insula, which are associated with greater anxiety, depression, posttraumatic stress disorder (PTSD) symptoms, and distress. These results provide insights for understanding the effects of these psychological and emotional factors on peripheral stress-related biobehavioral pathways known to contribute to cancer progression and long-term health outcomes. This line of work provides leads for understanding the brain-mediated mechanisms that may explain the health effects of psychosocial interventions in cancer patients and survivors. A multilevel and integrated model for distress management intervention effects on psychological adaptation, biobehavioral processes, cancer pathogenesis, and clinical outcomes is proposed for future research.

METHOD: Narrative literature review using articles from the PubMed, Scopus and Web of Science databases, and recommendations from health agencies conducted in April 2020.Results: Protective respiratory devices (particulate respirators) can be reused if it is clean, dry and their layers and shape are intact. To increase the durability of surgical masks, the use of paper towels to absorb moisture is suggested. Cloth masks are recommended, as long as they are washed properly for reuse. CONCLUSION: Despite the scarce number of studies on the reuse of masks, given the expansion of COVID-19 and the worldwide shortage of this equipment, health professionals and the population must be constantly updated on the recommendations for use of these protective devices.

Supratentorial hemangioblastomas in von Hippel-Lindau wild-type patients - case series and literature review.

BACKGROUND: Supratentorial hemangioblastoma is an uncommon lesion with few data available. Resemblance to other tumours represents a struggle concerning pre-operative diagnosis and management. OBJECTIVES: The aim of this study was to review the current literature, integrating two new cases with uncommon features. METHODS: A search of English language peer-reviewed articles in PubMed®, Cochrane Library®, Google Scholar® and summary of the current knowledge. RESULTS: A total of 162 cases, with no predominance between von Hippel-Lindau disease and wild-type sporadic lesions. The frontal lobe is the most common topography, followed by the pituitary stalk, with image resemblance to a glioma or a metastasis. From these, 20 cases revealed dural attachment, mimicking a meningioma. Symptoms are due to mass effect or epilepsy, with low haemorrhagic risk. Clinical outcome on supratentorial hemangioblastoma depends on resection extension, with no recognised complementary treatment. Post-operative follow-up is essential, even in wild-type, sporadic cases, concerning recent reports of tumour dissemination. CONCLUSIONS: This review compiles the main characteristics of supratentorial hemangioblastoma, that despite its rarity, should be a concern on differential diagnosis, treatment planning and expected prognosis.

Psychosocial oncology care resources in Europe: a study under the European Partnership for Action Against Cancer (EPAAC).

BACKGROUND: Cancer is a complex health problem requiring multidisciplinary care. There are clinical guidelines available in order to improve the process and outcomes of cancer care within Europe. However, strategic action is still needed in many European Union (EU) Member States to develop or improve national cancer control plans (NCCPs), which play a key role in cancer control and care. The current study clarifies the extent of implementation of psychosocial oncology care (PSOC) in the EU. METHOD: A survey methodology was used to cover four dimensions: (1) inclusion of PSOC in NCCPs; (2) structure and resources of PSOC delivery; (3) use of NCCP clinical guidelines; and (4) education and training resources available along with determination of training needs in PSOC. RESULTS: Twenty-seven (90%) countries returned questionnaires of which 21 (78%) include PSOC in their NCCP. However, only 10 (37%) reported having specific budgets for PSOC, 8 (30%) having nationally recommended PSOC clinical guidelines, and 6 countries (22%) reported having an official certification for PSOC education. CONCLUSION: Although many countries seem to have integrated PSOC into their NCCP, there is still much to do in terms of allocating resources and delivering psychosocial care equitably. Also, there is a need for improving training and certification in PSOC. The findings indicate the need to develop national policies concerning PSOC with clear targets for deliverables in an appropriate timetable in order that psychosocial services and existing clinical guidelines are implemented and fully integrated into EU NCCPs.

Colonização nasal por Staphylococcus aureus entre estudantes de Enfermagem: subsídios para monitorização / Colonización nasal por Staphylococcus aureus entre estudiantes de Enfermería: sugerencias para su monitoreo / Nasal colonization with Staphylococcus aureus in nursing students: ground for monitoring

RESUMO Objetivo: monitorar as cepas de Staphylococcus aureus resistentes ou não à oxacilina, entre estudantes da graduação em enfermagem, com ênfase no processo de colonização. Método: estudo transversal de prevalência, realizado com 138 estudantes de Enfermagem. As amostras biológicas da cavidade nasal foram coletadas em junho de 2015, utilizando-se swabs estéreis, posteriormente submetidos a testes confirmatórios de catalase e coagulase. Os Staphylococcus aureus isolados tiveram seus perfis de sensibilidade determinados por meio da técnica de Kirby Bauer. Foram realizadas análises descritivas, univariadas e bivariadas. Resultados: a prevalência de Staphylococcus aureus foi de 21,7. Com relação ao perfil de resistência, 24,1% das cepas se mostraram resistentes à oxacilina, sendo a ampicilina o antimicrobiano com maior resistência (82,8%). Conclusão: a cavidade nasal é importante reservatório de S. aureus em estudantes de Enfermagem. O perfil das linhagens isoladas evidencia o aumento da resistência de Staphylococcus aureus a antimicrobianos, como a oxacilina.

ABSTRACT Objective: to monitor bacterial strains of Staphylococcus aureus that are resistant or not to oxacillin in nursing undergraduate students, with an emphasis on the process of colonization. Method: cross-sectional prevalence study carried out with 138 nursing students. The biological samples of the nasal cavity were collected in June 2015, by means of sterile swabs, which were subsequently submitted to confirmatory tests of catalase and coagulase. Isolated Staphylococcus aureus had their sensitivity profile determined by means of the Kirby Bauer method. Descriptive, univariate and bivariate analyses were performed. Results: the prevalence of Staphylococcus aureus was 21.7. Regarding the resistance profile, 24.1% of strains were resistant to oxacillin, with ampicillin being the antimicrobial with the greatest resistance (82.8%). Conclusion: the nasal cavity is an important bacterial flora of S. aureus in nursing students. The profile of isolated strains highlights the increase of Staphylococcus aureus resistance to antimicrobials such as oxacillin.
