Phenomena Conflict, Anxiety, and Depression for Cancer Survivor One Year and After Have Therapy in General Hospital

Introduction. Psychosocial distress emerges in cancer disease. This research explores experience of conflict, anxiety, and depression in one year cancer survivor. Methods. Data were collected through in-depth semi structured interviews with fifteen participants when seeking treatment at a public hospital in Bandung. Result. There nine themes emerge: anxiety about cancer\u27s spread and recurrence, changing relationships with a partner, \u27labeling\u27 from oneself and others, physical discomfort along treatment, psychological discomfort along treatment, self-concept, religious/spiritual, hiding diagnose and complain, and deficit information about cancer. But, four themes among were not characterized with conflict, anxiety, and depression. Conflict, anxiety, and depression impact condition of the client cancer. Discussion. Experience of conflict, anxiety, and depression became the basis for the development of management system service and provision of facilities for integrated mental health nursing therapy

Astrocytes from cortex and striatum show differential responses to mitochondrial toxin and BDNF: Implications for protection of striatal neurons expressing mutant huntingtin

Background: Evidence shows significant heterogeneity in astrocyte gene expression and function. We previously demonstrated that brain-derived neurotrophic factor (BDNF) exerts protective effects on whole brain primary cultured rat astrocytes treated with 3-nitropropionic acid (3NP), a mitochondrial toxin widely used as an in vitro model of Huntington’s disease (HD). Therefore, we now investigated 3NP and BDNF effects on astrocytes from two areas involved in HD: the striatum and the entire cortex, and their involvement in neuron survival. Methods: We prepared primary cultured rat cortical or striatal astrocytes and treated them with BDNF and/or 3NP for 24 h. In these cells, we assessed expression of astrocyte markers, BDNF receptor, and glutamate transporters, and cytokine release. We prepared astrocyte-conditioned medium (ACM) from cortical and striatal astrocytes and tested its effect on a cellular model of HD. Results: BDNF protected astrocytes from 3NP-induced death, increased expression of its own receptor, and activation of ERK in both cortical and striatal astrocytes. However, BDNF modulated glutamate transporter expression differently by increasing GLT1 and GLAST expression in cortical astrocytes but only GLT1 expression in striatal astrocytes. Striatal astrocytes released higher amounts of tumor necrosis factor-α than cortical astrocytes in response to 3NP but BDNF decreased this effect in both populations. 3NP decreased transforming growth factor-β release only in cortical astrocytes, whereas BDNF treatment increased its release only in striatal astrocytes. Finally, we evaluated ACM effect on a cellular model of HD: the rat striatal neuron cell line ST14A expressing mutant human huntingtin (Q120) or in ST14A cells expressing normal human huntingtin (Q15). Neither striatal nor cortical ACM modified the viability of Q15 cells. Only ACM from striatal astrocytes treated with BDNF and ACM from 3NP + BDNF-treated striatal astrocytes protected Q120 cells, whereas ACM from cortical astrocytes did not.Conclusions: Data suggest that cortical and striatal astrocytes respond differently to mitochondrial toxin 3NP and BDNF. Moreover, striatal astrocytes secrete soluble neuroprotective factors in response to BDNF that selectively protect neurons expressing mutant huntingtin implicating that BDNF modulation of striatal astrocyte function has therapeutic potential against neurodegeneration.Fil: Saba, Julieta.

Unraveling the β-AMYLOID clearance by astrocytes: Involvement of metabotropic glutamate receptor 3, sAPPα, and class-A scavenger receptor

The mechanics of β-amyloid (Aβ) clearance by astrocytes has not been univocally described, with different mediators appearing to contribute to this process under different conditions. Our laboratory has demonstrated neuroprotective effects of astroglial subtype 3 metabotropic glutamate receptor (mGlu3R), which are dependent on the secreted form of the amyloid precursor protein (sAPPα) as well as on Aβ clearance; however, the mechanism underlying mGlu3R-induced Aβ uptake by astrocytes remains unclear. The present study shows that conditioned medium from mGlu3R-stimulated astrocytes increased Aβ uptake by naïve astrocytes through a mechanism dependent on sAPPα, since sAPPα depletion from conditioned medium inhibited Aβ phagocytosis. Concordantly, recombinant sAPPα also increased Aβ uptake. Since we show that both sAPPα and the mGlu3R agonist LY379268 increased expression of class-A scavenger receptor (SR-A) in astrocytes, we next determined whether SR-A mediates mGlu3R- or sAPPα-induced Aβ uptake by using astrocyte cultures derived from SR-A knockout mice. We found that the effects of LY379268 as well as sAPPα on Aβ uptake were abolished in SR-A-deficient astrocytes, indicating a major role for this scavenger receptor in LY379268- and sAPPα-stimulated Aβ clearance by astrocytes. We also show results of coimmunoprecipitation and functional assays offering evidence of possible heterotrimerization of sAPPα with Aβ and SR-A which could allow Aβ to enter the astrocyte. In conclusion the present paper describes a novel pathway for Aβ clearance by astrocytes involving sAPPα as an enhancer of SR-A-dependent Aβ phagocytosis.Fil: Durand, Daniela Elizabeth.

NDP-MSH reduces oxidative damage induced by palmitic acid in primary astrocytes

Recent findings relate obesity to inflammation in key hypothalamic areas for body weight control. Hypothalamic inflammation has also been related to oxidative stress. Palmitic acid (PA) is the most abundant free fatty acid found in food, and in vitro studies indicate that it triggers a pro-inflammatory response in the brain. Melanocortins are neuropeptides with proven anti-inflammatory and neuroprotective action mediated by melanocortin receptor 4 (MC4R), but little is known about the effect of melanocortins on oxidative stress. The aim of this study was to investigate whether melanocortins could alleviate oxidative stress induced by a high fat diet (HFD) model. We found that NDP-MSH treatment decreased PA-induced reactive oxygen species production in astrocytes, an effect blocked by the MC4R inhibitor JKC363. NDP-MSH abolished nuclear translocation of Nrf2 induced by PA and blocked the inhibitory effect of PA on superoxide dismutase (SOD) activity and glutathione levels while it also per se increased activity of SOD and γ-glutamate cysteine ligase (γ-GCL) antioxidant enzymes. However, HFD reduced hypothalamic MC4R and brain derived neurotrophic factor mRNA levels, thereby preventing the neuroprotective mechanism induced by melanocortins.Fil: Ramírez, Delia.

Odor pleasantness modulates functional connectivity in the olfactory hedonic processing network

Olfactory hedonic evaluation is the primary dimension of olfactory perception and thus central to our sense of smell. It involves complex interactions between brain regions associated with sensory, affective and reward processing. Despite a recent increase in interest, several aspects of olfactory hedonic evaluation remain ambiguous: uncertainty surrounds the communication between, and interaction among, brain areas during hedonic evaluation of olfactory stimuli with different levels of pleasantness, as well as the corresponding supporting oscillatory mechanisms. In our study we investigated changes in functional interactions among brain areas in response to odor stimuli using electroencephalography (EEG). To this goal, functional connectivity networks were estimated based on phase synchronization between EEG signals using the weighted phase lag index (wPLI). Graph theoretic metrics were subsequently used to quantify the resulting changes in functional connectivity of relevant brain regions involved in olfactory hedonic evaluation. Our results indicate that odor stimuli of different hedonic values evoke significantly different interaction patterns among brain regions within the olfactory cortex, as well as in the anterior cingulate and orbitofrontal cortices. Furthermore, significant hemispheric laterality effects have been observed in the prefrontal and anterior cingulate cortices, specifically in the beta ((13–30) Hz) and gamma ((30–40) Hz) frequency band

Ajuste por inflación contable. Efectos observados por su reanudación en 2018

En el escenario económico argentino durante las últimas décadas, emerge la inflación persistente como un factor preponderante por su incidencia en la elaboración de los informes contables destinados a terceros. En estudios anteriores se lograron identificar ciertos efectos en las mediciones del patrimonio y sus resultados producidos por la elaboración de estados contables en moneda nominal con relación a los que se hubieran determinado de haberse aplicado moneda homogénea. Se observó que los activos medidos al costo estaban subvaluados respecto de los valores de mercado; que el capital a mantener sin ajustar afectó la determinación del resultado del ejercicio, dependiendo de la combinación de los activos y pasivos monetarios que se mantenían dentro de la estructura patrimonial y las decisiones tomadas en función del mismo. En consecuencia, los informes contables se apartaron de la realidad que debían reflejar, para resultar útiles a usuarios desde la descontinuación del método de ajuste integral en el año 2003. Con su reanudación, la información contable revelada logró mayor aproximación a la realidad, al presentar la totalidad de sus elementos en moneda homogénea de cierre y permitir la determinación del RECPAM.Sobre la base del relevamiento en casos particulares, al contrastar los efectos producidos del mencionado ajuste en su primer ejercicio de aplicación para balances cerrados a partir del 31 de diciembre de 2018 se lograron obtener conclusiones que confirman las hipótesis teóricas planteadas en estudios anteriores. Así se observó que entidades con activos principalmente fijos y financiamiento preponderantemente de terceros, revirtieron un resultado nominal deficitario a uno superavitario en moneda homogénea. Lo contrario se observó en empresas con una baja cuantía de activos fijos y bajo endeudamiento. De allí sus implicancias en la distribución de resultados y determinación de impuestos.In the Argentine economic scenario during the last decades, persistent inflation emerges as a preponderant factor due to its incidence in the preparation of accounting reports destined for third parties. In previous studies it was possible to identify certain effects on the measurements of equity and its results produced by the preparation of financial statements in nominal currency in relation to those that would have been determined if the homogeneous currency had been applied. Assets measured at cost were found to be undervalued relative to market values; that the unadjusted capital to be maintained affected the determination of the result for the year, depending on the combination of monetary assets and liabilities that were maintained within the equity structure and the decisions made based on it. Consequently, the accounting reports departed from the reality that they should reflect, to be useful to users since the discontinuation of the comprehensive adjustment method in 2003. With its resumption, the disclosed accounting information achieved a greater approximation to reality, by presenting all of its elements in homogeneous closing currency and allow the determination of the RECPAM. Based on the survey in particular cases, when contrasting the effects produced by the aforementioned adjustment in its first year of application for balances closed as of December 31, 2018, conclusions were obtained that confirm the theoretical hypotheses raised in previous studies. Thus, it was observed that entities with mainly fixed assets and financing mainly from third parties reverted a deficit nominal result to a surplus in homogeneous currency. The opposite was observed in companies with a low amount of fixed assets and low indebtedness. Hence its implications in the distribution of results and determination of taxes

Murciélagos del Parque El Virrey, Bogotá

ilustraciones, fotografíasCuando estamos en los parques de nuestra capital, usualmente durante el día vemos a las mirlas de patas anaranjadas o a los copetones, en la noche ocasionalmente observamos algunas polillas, pero no vemos a los mamíferos alados que silenciosamente vuelan sobre los árboles: los murciélagos. Los murciélagos son los únicos mamíferos voladores ya que alimentan a sus crías con leche; además, ingieren su alimento por la boca, eliminan las heces por el ano y están cubiertos de pelo. Culturalmente son considerados ratones voladores o se les asocia con espíritus malignos, pero estas son solo percepciones erradas.

Experiences and lessons learned from 29 HPV vaccination programs implemented in 19 low and middle-income countries, 2009-2014

BACKGROUND: Cervical cancer is the greatest cause of age-weighted years of life lost in the developing world. Human papillomavirus (HPV) infection is associated with a high proportion of cervical cancers, and HPV vaccination may help to reduce the incidence of cancer. The aim of the study was to identify barriers, obstacles, and strategies and to analyze key concerns and lessons learned with respect to the implementation of HPV vaccination program in low- and middle-income countries. METHODS: The Gardasil Access Program (GAP) is a donation program established to enable organizations and institutions in eligible low-resource countries to gain operational experience designing and implementing HPV vaccination programs. This study used an online survey to capture the experiences and insights of program managers participating in the GAP. Different factors related to HPV vaccination program management were collected. A mixed-method approach enabled the presentation of both quantitative measurements and qualitative insights. RESULTS: Twenty-nine programs implemented by 23 institutions in 19 low- and middle-income countries were included. Twenty programs managers (97.7 %) reported that their institution implemented sensitization strategies about vaccination prior to the launch of vaccination campaign. The most frequently reported obstacles to HPV vaccination by the program managers were erroneous perceptions of population related to the vaccine’s safety and efficacy. Reaching and maintaining follow-up with target populations were identified as challenges. Insufficient infrastructure and human resources financing and the vaccine delivery method were identified as significant health system barriers. Coupling HPV vaccination with other health interventions for mothers of targeted girls helped to increase vaccination and cervical cancer screening. The majority of program managers reported that their programs had a positive impact on national HPV vaccination policy. The majority of institutions had national and international partners that provided support for human resources, technical assistance, and training and financial support for health professionals. CONCLUSION: Local organizations and institutions can implement successful HPV vaccination campaigns. Adequate and adapted planning and resources that support information sharing, sensitization, and mobilization are essential for such success. These results can inform the development of programs and policies related to HPV vaccination in low- and middle-income countries

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial
