RESUMO

The Peruvian guanaco (Lama guanicoe cacsilensis) is classified as being "in critical danger of extinction" by the government. In this study, we evaluate how the conflict between farmers and guanacos in the Susapaya and Estique Districts, Tacna Department (Southern Peru) may represent a threat to their survival. To evaluate the situation, we 1. Conducted field surveys to monitor guanaco presence, 2. Used available remote sensing data to map guanaco movement, and 3. interviewed the impacted farmers concerning their losses. Remote sensing data showed that sedentary guanaco family groups located in prime steppe vegetation habitats never entered agricultural areas, while field surveys showed that bachelor bands and solitary individuals did, perhaps seeking forage due to growing population pressure. Interview data found that 90% of community farmers felt that guanacos were a problem best resolved by better fencing (45%), hunting (19%), or increased security (16%), and 92% saw no value in the conservation of the species. Hunting is illegal, given the critically endangered status of guanacos in Peru, so additional efforts are needed to both educate those who feel guanacos are a menace and involve them in efforts to preserve the species.

RESUMO

The proteomic analysis of hairs, yarns or textiles has emerged as a powerful method to determine species of origin, mainly used in archaeozoological research and fraud control. Differentiation between the South American camelid (SAC) species (the wild guanaco and vicuña and their respective domesticates the llama and alpaca) is particularly challenging due to poor database information and significant hybridization between species. In this study, we analysed 41 modern and 4 archaeological samples from the four SACs species. Despite strong similarities with Old World Camelidae, we identified 7 peptides specific to SACs assigned to keratin K86 and the keratin-associated proteins KAP13-1 and KAP11-1. Untargeted multivariate analysis of the LC-MS data permitted to distinguish SAC species and propose discriminant features. MS/MS-based molecular networking combined with database-assisted de novo sequencing permitted to identify 5 new taxonomic peptides assigned to K33a, K81 and/or K83 keratins and KAP19-1. These peptides differentiate the two wild species, guanaco and vicuña. These results show the value of combining database search and untargeted metabolomic approaches for paleoproteomics, and reveal for the first time the potential of molecular networks to highlight deamidation related to diagenesis and cluster highly similar peptides related to interchain homologies or intra- or inter-specific polymorphism. SIGNIFICANCE: This study used an innovative approach combining multivariate analysis of LC-MS data together with molecular networking and database-assisted de novo sequencing to identify taxonomic peptides in palaeoproteomics. It constitutes the first attempt to differentiate between hair fibres from the four South American camelids (SACs) based on proteomic analysis of modern and archaeological samples. It provides different proteomic signatures for each of the four SAC species and proposes new SAC taxonomic peptides of interest in archaeozoology and fraud control. SACs have been extensively exploited since human colonization of South America but have not been studied to the extent of their economic, cultural and heritage importance. Applied to the analysis of ancient Andean textiles, our results should permit a better understanding of cultural and pastoral practices in South America. The wild SACs are endangered by poaching and black-market sale of their fibre. For the first time, our results provide discriminant features for the determination of species of origin of contraband fibre.

RESUMO

Neonatal domestic South American Camelid llamas and alpacas suffer from an enteric disease complex characterized by abdominal distention, lethargy, dehydration, and eventual fatal septicemia. Analysis of rectal swabs from neonatal alpacas suffering clinical diarrheas has constantly isolated Escherichia coli, mainly the EPEC and EHEC pathotypes. The present communication reports the results of molecular analysis of 226 E. coli strains from neonatal alpaca rectal swabs. The isolates were initially tested by multiple PCR, to identify E. coli virulence genes eae, bfp, Lt, Stx1, Stx2, sta, stab, and lt genes and a similar test to detect F4, F5, F6, F17, and F41fimbriae adhesin genes. Forty-two of the 226 (18.5%) isolates tested positive for at least one pathogenic gene, 25 of the 42 were classified as EPEC (3 positives for only eae and 22 for both eae and bfp) and the remaining 17 were classified as EHEC. Twenty-four (57%) of the 42 isolates tested positive to F17 adhesin while one was positive for both F6 and F17.

RESUMO

Importance: Philanthropy is an increasingly important source of support for health care institutions. There is little empirical evidence to inform ethical guidelines. Objective: To assess public attitudes regarding specific practices used by health care institutions to encourage philanthropic donations from grateful patients. Design, Setting, and Participants: Using the Ipsos KnowledgePanel, a probability-based sample representative of the US population, a survey solicited opinions from a primary cohort representing the general population and 3 supplemental cohorts (with high income, cancer, and with heart disease, respectively). Exposures: Web-based questionnaire. Main Outcomes and Measures: Descriptive analyses (with percentages weighted to make the sample demographically representative of the US population) evaluated respondents' attitudes regarding the acceptability of strategies hospitals may use to identify, solicit, and thank donors; perceptions of the effect of physicians discussing donations with their patients; and opinions regarding gift use and stewardship. Results: Of 831 individuals targeted for the general population sample, 513 (62%) completed surveys, of whom 246 (48.0%) were women and 345 (67.3%) non-Hispanic white. In the weighted sample, 47.0% (95% CI, 42.3%-51.7%) responded that physicians giving patient names to hospital fundraising staff after asking patients' permission was definitely or probably acceptable; 8.5% (95% CI, 5.7%-11.2%) endorsed referring without asking permission. Of the participants, 79.5% (95% CI, 75.6%-83.4%) reported it acceptable for physicians to talk to patients about donating if patients have brought it up; 14.2% (95% CI, 10.9%-17.6%) reported it acceptable when patients have not brought it up; 9.9% (95% CI, 7.1%-12.8%) accepted hospital development staff performing wealth screening using publicly available data to identify patients capable of large donations. Of the participants, 83.2% (95% CI, 79.5%-86.9%) agreed that physicians talking with their patients about donating may interfere with the patient-physician relationship. For a hypothetical patient who donated $1 million, 50.1% (95% CI, 45.4%-54.7%) indicated it would be acceptable for the hospital to show thanks by providing nicer hospital rooms, 26.0% (95% CI, 21.9%-30.1%) by providing expedited appointments, and 19.8% (95% CI, 16.1%-23.5%) by providing physicians' cell phone numbers. Conclusions and Relevance: In this survey study of participants drawn from the general US population, a substantial proportion did not endorse legally allowable approaches for identifying, engaging, and thanking patient-donors.

RESUMO

BACKGROUND: Despite their regional economic importance and being increasingly reared globally, the origins and evolution of the llama and alpaca remain poorly understood. Here we report reference genomes for the llama, and for the guanaco and vicuña (their putative wild progenitors), compare these with the published alpaca genome, and resequence seven individuals of all four species to better understand domestication and introgression between the llama and alpaca. RESULTS: Phylogenomic analysis confirms that the llama was domesticated from the guanaco and the alpaca from the vicuña. Introgression was much higher in the alpaca genome (36%) than the llama (5%) and could be dated close to the time of the Spanish conquest, approximately 500 years ago. Introgression patterns are at their most variable on the X-chromosome of the alpaca, featuring 53 genes known to have deleterious X-linked phenotypes in humans. Strong genome-wide introgression signatures include olfactory receptor complexes into both species, hypertension resistance into alpaca, and fleece/fiber traits into llama. Genomic signatures of domestication in the llama include male reproductive traits, while in alpaca feature fleece characteristics, olfaction-related and hypoxia adaptation traits. Expression analysis of the introgressed region that is syntenic to human HSA4q21, a gene cluster previously associated with hypertension in humans under hypoxic conditions, shows a previously undocumented role for PRDM8 downregulation as a potential transcriptional regulation mechanism, analogous to that previously reported at high altitude for hypoxia-inducible factor 1α. CONCLUSIONS: The unprecedented introgression signatures within both domestic camelid genomes may reflect post-conquest changes in agriculture and the breakdown of traditional management practices.

RESUMO

Grateful patients provide substantial philanthropic funding for health care institutions, resulting in important societal benefits. Although grateful patient fundraising (GPFR) is widespread, it raises an array of ethical issues for patients, physicians, development professionals, and institutions. These issues have not been described comprehensively, and there is insufficient guidance to inform the ethical practice of GPFR. Consequently, the authors convened a "Summit on the Ethics of Grateful Patient Fundraising," with the goal of identifying primary ethical issues in GPFR and offering recommendations regarding how to manage them. Participants were 29 experts from across the United States who represented the perspectives of bioethics, clinical practice, development, law, patients, philanthropy, psychology, and regulatory compliance. Intensive discussions resulted in articulating ethical issues for physicians and other clinicians (discussions with patients about philanthropy; physician-initiated discussions; clinically vulnerable patients; conflicts of obligation and equity regarding physician's time, attention, and responsiveness and the provision of special services; and transparency and respecting donor intent) as well as for development officers and institutions (transparency in the development professional-donor relationship; impact on clinical care; confidentiality and privacy; conflicts of interest; institution-patient/donor relationship; concierge services for grateful patients; scientific merit and research integrity; transparency in use of philanthropic gifts; and institutional policies and training in responsible GPFR). While these recommendations promise to mitigate some of the ethical issues associated with GPFR, important next steps include conducting research on the ethical issues in GPFR, disseminating these recommendations, developing standardized training for clinicians regarding them, and revising them as warranted.

RESUMO

OBJECTIVE: Protein-energy wasting is common in end-stage renal disease patients undergoing dialysis and is strongly associated with mortality and adverse outcomes. Intradialytic oral nutritional supplements (ONS) reduce risk of mortality in these patients. Large studies characterizing the impact of ONS on other outcomes are lacking. We assessed the associations between administration of ONS and clinical and nutritional outcomes. DESIGN: Retrospective evaluation of a pilot program providing ONS to patients at a large dialysis organization in the United States. The pilot program provided ONS to in-center hemodialysis patients with serum albumin ≤3.5 g/dL at 408 facilities. SUBJECTS: ONS patients were compared to matched controls with serum albumin ≤3.5 g/dL, identified from facilities not participating in the ONS program (n = 3,374 per group). INTERVENTION: Receipt of ONS. MAIN OUTCOME MEASURES: Death, missed dialysis treatments, hospitalizations, serum albumin, normalized protein catabolic rate, and postdialysis body weight were abstracted from large dialysis organization electronic medical records. RESULTS: There was a 69% reduction in deaths (hazard ratio = 0.31; 95% confidence interval = 0.25-0.39), and 33% fewer missed dialysis treatments (incidence rate ratio = 0.77; 95% confidence interval = 0.73-0.82) among ONS patients compared to controls (P < .001 for both). The effects of ONS on nutritional indices were mixed: serum albumin was lower, whereas normalized protein catabolic rate values, a surrogate for dietary protein intake, and postdialysis body weights were higher for ONS patients compared to controls during follow-up. CONCLUSIONS: Our evaluation confirmed the beneficial effects of ONS in reducing mortality and improving some indices of nutritional status for hypoalbuminemic hemodialysis patients. We also report the novel finding that ONS can reduce the number of missed dialysis treatments. These results support the use of intradialytic ONS as an effective intervention to improve the outcomes in hemodialysis patients with low serum albumin.

RESUMO

The causes of Late Pleistocene megafaunal extinctions (60,000 to 11,650 years ago, hereafter 60 to 11.65 ka) remain contentious, with major phases coinciding with both human arrival and climate change around the world. The Americas provide a unique opportunity to disentangle these factors as human colonization took place over a narrow time frame (~15 to 14.6 ka) but during contrasting temperature trends across each continent. Unfortunately, limited data sets in South America have so far precluded detailed comparison. We analyze genetic and radiocarbon data from 89 and 71 Patagonian megafaunal bones, respectively, more than doubling the high-quality Pleistocene megafaunal radiocarbon data sets from the region. We identify a narrow megafaunal extinction phase 12,280 ± 110 years ago, some 1 to 3 thousand years after initial human presence in the area. Although humans arrived immediately prior to a cold phase, the Antarctic Cold Reversal stadial, megafaunal extinctions did not occur until the stadial finished and the subsequent warming phase commenced some 1 to 3 thousand years later. The increased resolution provided by the Patagonian material reveals that the sequence of climate and extinction events in North and South America were temporally inverted, but in both cases, megafaunal extinctions did not occur until human presence and climate warming coincided. Overall, metapopulation processes involving subpopulation connectivity on a continental scale appear to have been critical for megafaunal species survival of both climate change and human impacts.

RESUMO

There has been recent debate over stratigraphic markers used to demarcate the Anthropocene from the Holocene Epoch. However, many of the proposed markers are found only in limited areas of the world or do not reflect human impacts on the environment. Here we show that spheroidal carbonaceous particles (SCPs), a distinct form of black carbon produced from burning fossil fuels in energy production and heavy industry, provide unambiguous stratigraphic markers of the human activities that have rapidly changed planet Earth over the last century. SCPs are found in terrestrial and marine sediments or ice cores in every continent, including remote areas such as the high Arctic and Antarctica. The rapid increase in SCPs mostly occurs in the mid-twentieth century and is contemporaneous with the 'Great Acceleration'. It therefore reflects the intensification of fossil fuel usage and can be traced across the globe. We integrate global records of SCPs and propose that the global rapid increase in SCPs in sedimentary records can be used to inform a Global Standard Stratigraphic Age for the Anthropocene. A high-resolution SCP sequence from a lake or peatland may provide the much-needed 'Golden Spike' (Global Boundary Stratotype Section and Point).

RESUMO

To determine the impact of farming over vicuña population in Peru, serum samples were collected from 207 vicuñas (126 captive vicuñas and 81 free-ranging vicuñas) and 614 domestic South American camelids (571 alpacas and 43 llamas), in ten Andean communities at the Salinas y Aguada Blanca reserve, province of Arequipa, southern Peru. Samples were tested for the presence of leptospirosis, foot and mouth disease (FMD), bovine viral diarrhea (BVD), bovine herpesvirus type 1 (BHV-1), brucellosis, bluetongue disease (BT), paratuberculosis, and neosporosis. Serological results showed that 1.9% (4/207) of vicuñas, 18.6% (106/571) of alpacas, and 23.3% (10/43) of llamas were positive to one or more Leptospira serovars. One percent of vicuñas (2/207) and 2.4% of domestic camelids (15/614) had Neospora caninum antibodies tested by ELISA, but only two vicuñas and two alpacas were confirmed by Western blot. Epidemiological evaluation found an association of leptospirosis to sex and age (p < 0.001), with female subjects older than 2.5 years at higher risk of infection. Interestingly, antibodies against Leptospira serovars were only found in captive vicuñas. This is the first study where health status of free-ranging and captive vicuñas has been compared. Results indicate minimal to nil presence of FMD, BVD, BHV-1, brucellosis, BT, paratuberculosis, and neosporosis allied to health disorders in our sample. The detection of seropositive animals against Leptospira, however, unveils the likely significance of leptospirosis in wild and domestic South American camelids, the impact of mixed husbandry over vicuña population and the risk to human health.

RESUMO

CONTEXT: Availability of hospice and palliative care is increasing, despite lack of a clear national strategy for developing and evaluating their penetration into and impact on the target population. OBJECTIVES: To determine whether targeted investment (i.e., strategic grants made by one charitable foundation) in hospice and palliative care in one U.S. state (North Carolina [NC]) led to improved access to end-of-life care services as indicated by hospice utilization. METHODS: Access was measured by the death service ratio (DSR), defined as the proportion of people who died and were served by hospice for at least one day before death. Calculation of the DSR is based on counts of patients accessing hospice by county in a given year (numerator) and U.S. Census projected population data for that county (denominator). Multilevel modeling was the primary analytic strategy used to generate two models: 1) comparison of the DSR in counties with vs. without philanthropic funding and 2) relationship between years since receipt of a philanthropic grant and DSR. RESULTS: In NC, the average DSR increased from 20.7% in 2003 to 35.8% in 2009 (55% increase). In 2009, 82 of 100 NC counties had a DSR below the U.S. average (41.6%). In Model 1, significant associations were found between county population and DSR (P=0.03) and between receipt of philanthropic funding and DSR (P=0.01); on average, funded counties had a DSR that was 2.63 percentage points higher than unfunded counties. CONCLUSION: Receipt of philanthropic funding appeared to be associated with improved access to palliative care and hospice services in NC.

RESUMO

CONTEXT: In the U.S., the number of hospital-based palliative care programs has increased rapidly, but availability of outpatient palliative care remains limited. Multiple barriers impede the financial viability of these programs. Four Seasons, a nonprofit organization in western North Carolina, delivers a full spectrum of palliative care in hospitals, nursing homes, assisted living facilities, patients' homes, and outpatient clinics; its catchment area encompasses approximately 350,000 people. Initially focused on hospice care, Four Seasons added its palliative care program in 2003. Before the inquiry described herein, financial losses from outpatient palliative care (2003-2008) were escalating. OBJECTIVES: We explored organizational and financial barriers to sustainability of palliative care, so as to 1) identify reasons for financial losses; 2) devise and implement solutions; and 3) develop a sustainable model for palliative care delivery across settings, including the outpatient setting. METHODS: In 2008, Four Seasons's palliative care program served 305 patients per day (average) with 10.5 providers (physicians, nurse practitioners, and physician assistants); financial losses approached $400,000 per year. We used Quality Assessment and Performance Improvement cycles to identify challenges to and inefficiencies in service provision, developed targeted strategies for overcoming identified barriers to cost-efficiency, instituted these measures, and tracked results. RESULTS: In 2011, Four Seasons served 620 palliative care patients per day (average) with 14 providers; financial losses decreased by 40%. CONCLUSION: With health care reform promoting integration of care across settings, outpatient palliative care will gain importance in the health care continuum. Process changes can help reduce financial losses that currently impede outpatient palliative care programs.

RESUMO

CONTEXT: Although research activity in palliative care is rapidly increasing, the composition of published studies--in terms of significant research characteristics--has not yet been well described. OBJECTIVES: To describe the topics of and funding for palliative care studies reported in the three hospice and palliative care journals with the highest impact factors (Journal of Pain and Symptom Management, Palliative Medicine, and Journal of Palliative Medicine). METHODS: This was a substudy of a larger bibliographic study. The targeted journals were searched for 2007 using a previously validated Ovid MEDLINE filter for palliative care. All empirical palliative care studies were included. Articles were classified according to topics (palliative care patient, caregiver/family, health professional, service provision, tool development, healthy volunteer, medication compatibility, community), study type (intervention, nonintervention), country of origin, and funding source (pharmaceutical company, other funder, unfunded). RESULTS: Of 409 citations identified, the search yielded 189 eligible articles. Most articles were descriptive/observational. Approximately half were unfunded. Caregivers, healthy volunteers, and health service research were the least frequent topics for research. Only five randomized controlled trials were reported. CONCLUSION: Although there is a broad range of research undertaken in palliative care, few studies generate high-level evidence, with data showing a relative lack of funding for hospice and palliative care studies.

RESUMO

CONTEXT: In specialist hospice and palliative care services, variations occur in diagnoses and prognoses of subpopulations referred, service configuration, and the health systems delivering care. These three levels of variation limit the ability to generalize study findings. OBJECTIVES: This article reports on coding one year of palliative care research using a previously developed checklist. The aims were to 1) quantify current reporting of factors related to generalizability in specialist palliative care research; 2) review and potentially refine the checklist in light of the first aim; 3) demonstrate the feasibility of collecting these data; and 4) set out simple processes to aid researchers in reporting, and clinicians in applying, new research evidence in hospice and palliative care. METHODS: A previously published checklist (five domains, 14 core subdomains, and 24 noncore subdomains) was used to code all research articles (n=189) published in 2007 in the three leading palliative care research journals. RESULTS: The most frequently reported subdomains were patient age, gender, and diagnosis; model of service delivery; and patient performance status. Data in subdomains, including time from referral to death, socioeconomic indices, and ethnicity, were rarely reported; none reported whole-of-service or whole-of-population data. In total, 2646 (189×14) core subdomains could have been reported. Data were provided in 28% (746/2646). CONCLUSION: Checklists such as the Consolidated Standards of Reporting Trials evaluate study design, focusing mainly on internal validity. The proposed checklist deals with specific content of hospice and palliative care, focusing on external validity.

RESUMO

Although dyspnea is frequently encountered in the palliative care setting, its optimal management remains uncertain. Clinical approaches begin with accurate assessment, as delineated in part one of this two-part series. Comprehensive dyspnea assessment, which encompasses the physical, emotional, social, and spiritual aspects of this complex symptom, guide the clinician in choosing therapeutic approaches herein presented as part two. Global management of dyspnea is appropriate both as complementary to disease-targeted treatments that target the underlying etiology, and as the sole focus when the symptom has become intractable, disease is maximally treated, and goals of care shift to comfort and quality of life. In this setting, current evidence supports the use of oral or parenteral opioids as the mainstay of dyspnea management, and of inhaled furosemide and anxiolytics as adjuncts. Nonpharmacologic interventions such as acupuncture and pulmonary rehabilitation have potential effectiveness, although further research is needed, and use of a simple fan warrants consideration given its potential benefit and minimal burden and cost.

RESUMO

BACKGROUND: Quality measurement in palliative care requires robust data from standardized data collection processes. We developed and tested the feasibility of the Quality Data Collection Tool version 1.0 (QDACTv1.0) for use in community-based palliative care. MEASURES: To evaluate for implementation barriers, we tested feasibility, acceptability, and utility of the QDACTv1.0 by reviewing use patterns, surveying clinician users, and reporting conformance with quality metrics. INTERVENTION: Comprising 37 questions within five domains, QDACTv1.0 was launched in May 2008 for data collection at point of care. OUTCOMES: Through March 2011, data on 5959 patients in 19,734 visits have been collected. We observed steady quarterly growth in data collection, positive clinician feedback, and successful mapping of data to quality metrics. Information gathered characterized practice variations and suggested quality improvement initiatives. Clinician feedback has driven updating to Quality Data Collection Tool version 2.0. CONCLUSIONS/LESSONS LEARNED: Standardized data collection is feasible in routine community-based palliative care and is valuable for quality monitoring.

RESUMO

BACKGROUND: Dyspnea is a common symptom experienced by many patients with chronic, life-threatening, and/or life-limiting illnesses. Although it can be defined and measured in several ways, dyspnea is best described directly by patients through regular assessment, as its burdens exert a strong influence on the patient's experience throughout the trajectory of serious illness. Its significance is amplified due to its impact on family and caregivers. DISCUSSION: Anatomic and physiologic changes associated with dyspnea, and cognitive perceptions related to patients and the underlying disease, provide insights into how to shape interventions targeting this oppressive symptom. Additionally, as described in the concept of "total dyspnea," the complex etiology and manifestation of this symptom require multidisciplinary treatment plans that focus on psychological, social, and spiritual distress as well as physical components. Several validated assessment tools are available for clinical and research use, and choice of method should be tailored to the individual patient, disease, and care setting in the context of patient-centered care. CONCLUSION: This article, the first in a two-part series, reviews the identification and assessment of dyspnea, the burden it entails, and the underlying respiratory and nonrespiratory etiologies that may cause or exacerbate it.

RESUMO

Accompanying the ascendance of cancer as a leading cause of death worldwide is a new set of global health priorities focused on palliative care--the relief of symptoms and suffering, optimization of functional status, and quality of life for those with advanced, potentially life-limiting illnesses. In high-income countries, palliative care improves outcomes for patients, caregivers, provider organizations, and health systems. Data are not yet available to demonstrate similar benefits in low- and middle-income countries, where access to even the most basic palliative interventions (eg, opioids for pain management) is inadequate and unevenly distributed. This article describes current global disparities in the availability of palliative care. We make the case for international prioritization of palliative care as a critical strategy for improving outcomes for people with cancer and their caregivers worldwide.
