Giving In A Time Of Terrorism

Recent research in psychology suggest that altruism and altruistic decisions may, in fact, be endogenous and depend on the social situation in which people find themselves. People are more likely to be altruistic, to give to charities and others in need, when they feel secure and safe. This paper looks at the implications of a person’s perceived state of security on giving now that there are terrorist threats in the U.S. We use data from the Center on Philanthropy Panel Study (COPPS), and the Panel Study of Income Dynamics (the PSID) to test for endogenous changes in giving and volunteering from before and after the 2001 terrorist attacks. We find evidence indicating that increasing uncertainty resulted in a decline in the giving of both money and time, holding other variables constant, but the relationship is not significant

Giving Patterns By Religious And Non-Religions People

Using the Oaxaca-Blinder (1994) decomposition method to compare the giving levels of money and time of those who claim to attend religious services on a regular basis with those who do not, we find that on average religious people donate more money and time than non-religious people; although a large portion of the average difference is unexplained. We propose that these differences arise from a culture of giving in which religious people are embedded. It may be that individuals who are religious are more likely to be exposed to a culture that encourages giving and volunteering, and will therefore be more likely to give and volunteer

Effects Of Socio-Economic Characteristics On The Medication Of Children For Attention-Deficit/Hyperactivity Disorder (ADHD)

The diagnosis and medication of the illness known as Attention deficit/hyperactivity disorder (ADHD) has been shown to exhibit patterns unexpected from a medical condition that is randomly distributed throughout the population. This research uses new data to show statistically significant relationships between the medication of children for ADHD and several socio-economic characteristics. Most alarming is the fact that the significant relationships between medication and race and gender are robust, even when other socioeconomic characteristics are controlled for

The Non-optimality of For-Profit Firms Acting as Philanthropic Agents

We present a model of the nonprofit organization that leads to an allocation in the economy that is Pareto Optimal. This is in contrast to the usual assumption that an economy in which individuals exhibit altruism will not lead to a Pareto Optimal outcome.  The presence of nonprofit organizations that function according to this model leads to an outcome in the economy that is Pareto Optimal. The result of Pareto Optimality is based on several assumptions, including the assumption that nonprofit organizations believe that they will not be earning any profit that may be brought forward to the following year. This result suggests an additional reason for the tradition in the United States of absolving nonprofit organizations and donors to such organizations from paying income taxes on such donations. The nonprofit organizations, by acting according to this model, are performing an important economic role in the economy by restoring Pareto Optimality to the economy

Systemic inflammation and pro-inflammatory cytokine profile predict response to checkpoint inhibitor treatment in NSCLC: a prospective study

Treatment with single agent immune checkpoint inhibitors (ICIs) has tremendously changed second line therapy in NSCLC. However, there are still no reliable biomarkers predicting response and survival in this group of patients. PD-L1 revealed to be a correlating, but no perfect marker. Therefore, we sought to investigate in this prospective study, whether inflammation status and cytokine profile could serve as additional biomarkers guiding treatment decision for single agent ICIs in NSCLC. 29 stage IV NSCLC patients receiving single agent PD-1 checkpoint-inhibitor in second line were prospectively enrolled. Inflammatory scores and cytokine profiles (IL-6, IL-8, IL-10, IFN-γ and TNFα) have been obtained before treatment and at the time of the first staging. Cytokine profiles were correlated with response and survival. Patients with signs of pre-therapeutic inflammation (elevated, NLR, SII, IL-6, IL-8) showed significantly lower response to ICI treatment and reduced PFS. Contrary, elevated levels of IFN-γ revealed to characterize a subgroup of patients, who significantly benefits from ICI treatment. Furthermore, low systemic inflammation and high levels of IFN-γ characterized patients with long term-response to ICI treatment. Pre-therapeutic assessment of inflammation and cytokine profiles has the ability to predict response and survival in NSCLC patients treated with single agent ICIs

One year ago not business as usual: Wound management, infection and psychoemotional control during tertiary medical care following the 2004 Tsunami disaster in southeast Asia

INTRODUCTION: Following the 2004 tsunami disaster in southeast Asia severely injured tourists were repatriated via airlift to Germany. One cohort was triaged to the Cologne-Merheim Medical Center (Germany) for further medical care. We report on the tertiary medical care provided to this cohort of patients. METHODS: This study is an observational report on complex wound management, infection and psychoemotional control associated with the 2004 Tsunami disaster. The setting was an adult intensive care unit (ICU) of a level I trauma center and subjects included severely injured tsunami victims repatriated from the disaster area (19 to 68 years old; 10 females and 7 males with unknown co-morbidities). RESULTS: Multiple large flap lacerations (2 × 3 to 60 × 60 cm) at various body sites were characteristic. Lower extremities were mostly affected (88%), followed by upper extremities (29%), and head (18%). Two-thirds of patients presented with combined injuries to the thorax or fractures. Near-drowning involved the aspiration of immersion fluids, marine and soil debris into the respiratory tract and all patients displayed signs of pneumonitis and pneumonia upon arrival. Three patients presented with severe sinusitis. Microbiology identified a variety of common but also uncommon isolates that were often multi-resistant. Wound management included aggressive debridement together with vacuum-assisted closure in the interim between initial wound surgery and secondary closure. All patients received empiric anti-infective therapy using quinolones and clindamycin, later adapted to incoming results from microbiology and resistance patterns. This approach was effective in all but one patient who died due to severe fungal sepsis. All patients displayed severe signs of post-traumatic stress response. CONCLUSION: Individuals evacuated to our facility sustained traumatic injuries to head, chest, and limbs that were often contaminated with highly resistant bacteria. Transferred patients from disaster areas should be isolated until their microbial flora is identified as they may introduce new pathogens into an ICU. Successful wound management, including aggressive debridement combined with vacuum-assisted closure was effective. Initial anti-infective therapy using quinolones combined with clindamycin was a good first-line choice. Psychoemotional intervention alleviated severe post-traumatic stress response. For optimum treatment and care a multidisciplinary approach is mandatory

Transcriptional profiling of degraded RNA in cryopreserved and fixed tissue samples obtained at autopsy

BACKGROUND: Traditional multiplexed gene expression methods require well preserved, intact RNA. Such specimens are difficult to acquire in clinical practice where formalin fixation is the standard procedure for processing tissue. Even when special handling methods are used to obtain frozen tissue, there may be RNA degradation; for example autopsy samples where degradation occurs both pre-mortem and during the interval between death and cryopreservation. Although specimens with partially degraded RNA can be analyzed by qRT-PCR, these analyses can only be done individually or at low levels of multiplexing and are laborious and expensive to run for large numbers of RNA targets. METHODS: We evaluated the ability of the cDNA-mediated Annealing, Selection, extension, and Ligation (DASL) assay to provide highly multiplexed analyses of cryopreserved and formalin fixed, paraffin embedded (FFPE) tissues obtained at autopsy. Each assay provides data on 1536 targets, and can be performed on specimens with RNA fragments as small as 60 bp. RESULTS: The DASL performed accurately and consistently with cryopreserved RNA obtained at autopsy as well as with RNA extracted from formalin-fixed paraffin embedded tissue that had a cryopreserved mirror image specimen with high quality RNA. In FFPE tissue where the cryopreserved mirror image specimen was of low quality the assay performed reproducibly on some but not all specimens. CONCLUSION: The DASL assay provides reproducible results from cryopreserved specimens and many FFPE specimens obtained at autopsy. Gene expression analyses of these specimens may be especially valuable for the study of non-cancer endpoints, where surgical specimens are rarely available

Construction of a computable cell proliferation network focused on non-diseased lung cells

<p>Abstract</p> <p>Background</p> <p>Critical to advancing the systems-level evaluation of complex biological processes is the development of comprehensive networks and computational methods to apply to the analysis of systems biology data (transcriptomics, proteomics/phosphoproteomics, metabolomics, etc.). Ideally, these networks will be specifically designed to capture the normal, non-diseased biology of the tissue or cell types under investigation, and can be used with experimentally generated systems biology data to assess the biological impact of perturbations like xenobiotics and other cellular stresses. Lung cell proliferation is a key biological process to capture in such a network model, given the pivotal role that proliferation plays in lung diseases including cancer, chronic obstructive pulmonary disease (COPD), and fibrosis. Unfortunately, no such network has been available prior to this work.</p> <p>Results</p> <p>To further a systems-level assessment of the biological impact of perturbations on non-diseased mammalian lung cells, we constructed a lung-focused network for cell proliferation. The network encompasses diverse biological areas that lead to the regulation of normal lung cell proliferation (Cell Cycle, Growth Factors, Cell Interaction, Intra- and Extracellular Signaling, and Epigenetics), and contains a total of 848 nodes (biological entities) and 1597 edges (relationships between biological entities). The network was verified using four published gene expression profiling data sets associated with measured cell proliferation endpoints in lung and lung-related cell types. Predicted changes in the activity of core machinery involved in cell cycle regulation (RB1, CDKN1A, and MYC/MYCN) are statistically supported across multiple data sets, underscoring the general applicability of this approach for a network-wide biological impact assessment using systems biology data.</p> <p>Conclusions</p> <p>To the best of our knowledge, this lung-focused Cell Proliferation Network provides the most comprehensive connectivity map in existence of the molecular mechanisms regulating cell proliferation in the lung. The network is based on fully referenced causal relationships obtained from extensive evaluation of the literature. The computable structure of the network enables its application to the qualitative and quantitative evaluation of cell proliferation using systems biology data sets. The network is available for public use.</p

Rare coding variants in PLCG2, ABI3, and TREM2 implicate microglial-mediated innate immunity in Alzheimer's disease

We identified rare coding variants associated with Alzheimer’s disease (AD) in a 3-stage case-control study of 85,133 subjects. In stage 1, 34,174 samples were genotyped using a whole-exome microarray. In stage 2, we tested associated variants (P<1×10-4) in 35,962 independent samples using de novo genotyping and imputed genotypes. In stage 3, an additional 14,997 samples were used to test the most significant stage 2 associations (P<5×10-8) using imputed genotypes. We observed 3 novel genome-wide significant (GWS) AD associated non-synonymous variants; a protective variant in PLCG2 (rs72824905/p.P522R, P=5.38×10-10, OR=0.68, MAFcases=0.0059, MAFcontrols=0.0093), a risk variant in ABI3 (rs616338/p.S209F, P=4.56×10-10, OR=1.43, MAFcases=0.011, MAFcontrols=0.008), and a novel GWS variant in TREM2 (rs143332484/p.R62H, P=1.55×10-14, OR=1.67, MAFcases=0.0143, MAFcontrols=0.0089), a known AD susceptibility gene. These protein-coding changes are in genes highly expressed in microglia and highlight an immune-related protein-protein interaction network enriched for previously identified AD risk genes. These genetic findings provide additional evidence that the microglia-mediated innate immune response contributes directly to AD development

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder
