Lived Experiences of Diversity Visa Lottery Immigrants in the United States

Every year approximately 50,000 people immigrate to the United States through the avenue referred to as the Diversity Visa (DV) Lottery. In this article, the authors present a literature review of immigration to the U.S. through the DV Lottery, reflect on their own immigration histories, and utilize phenomenology to investigate and describe participant feelings, expectations, and experiences as DV Lottery immigrants. Participants experienced mixed feelings, including high expectations prior to and difficulties after immigrating to the U.S. Findings presented include (a) life experienced in the U.S.; (b) access to learning and training opportunities; and (c) recommended support future DV Lottery immigrants

Economic Burden of Community-Acquired Pneumonia among Adults in the Philippines: Its Equity and Policy Implications in the Case Rate Payments of the Philippine Health Insurance Corporation

AbstractObjectivesTo determine 1) the cost of hospitalization, the 1-week postdischarge cost, the total cost, and the economic burden of community-acquired pneumonia among patients aged 19 years or older in the Philippines and 2) the difference between the estimated costs and the Philippine Health Insurance Corporation (PhilHealth) pneumonia case rate payments.MethodsThe study involved two tertiary private hospitals in the Philippines. Using the societal perspective, both health care and non–health care costs were determined. A base-case analysis and sensitivity analyses were performed, and the economic burden of pneumonia was determined using PhilHealth claims.ResultsThe estimated cost of hospitalization for community-acquired pneumonia-moderate risk (CAP-MR) ranged from Philippine peso (PHP) 36,153 to 113,633 (US $852–2678) and its 1-week postdischarge cost ranged from PHP1450 to 8800 (US$34–207). The cost of hospitalization for community-acquired pneumonia-high risk (CAP-HR) ranged from PHP104,544 to 249,695 (US $2464–5885) and PHP101,248 to 243, 495 (US$2386–5739) using invasive and noninvasive ventilation, respectively. The postdischarge cost for CAP-HR ranged from PHP1716 to 10,529 (US $40–248). If only health care cost was considered, the cost ranged from PHP24,403 to 89,433 for CAP-MR and PHP92,848 to 213,395 for CAP-HR. The present PhilHealth case rate payments are PHP15,000 (US$354) and PHP32,000 (US $754) for CAP-MR and CAP-HR, respectively. Based on the number of PhilHealth claims for 2012 and the estimated health care cost, the economic burden of pneumonia in 2012 was PHP8.48 billion for CAP-MR and PHP643.76 million for CAP-HR.ConclusionsThe estimated health care cost of hospitalization is markedly higher than the PhilHealth case rate payments. As per the study results, the economic burden of pneumonia is, thus, significantly higher than PhilHealth estimates

Common variants in Alzheimer’s disease and risk stratification by polygenic risk scores

We first perform a large genetic association study by merging all available case-control datasets and by-proxy study results (discovery n = 409,435 and validation size n = 58,190). Here, we add six variants associated with Alzheimer's disease risk (near APP, CHRNE, PRKD3/NDUFAF7, PLCG2 and two exonic variants in the SHARPIN gene). Assessment of the polygenic risk score and stratifying by APOE reveal a 4 to 5.5 years difference in median age at onset of Alzheimer's disease patients in APOE ɛ4 carriers. Because of this study, the underlying mechanisms of APP can be studied to refine the amyloid cascade and the polygenic risk score provides a tool to select individuals at high risk of Alzheimer's disease

PREVALENCE OF DRUG RESISTANCE AND VIRULENCE FEATURES IN Salmonella spp. ISOLATED FROM FOODS ASSOCIATED OR NOT WITH SALMONELLOSIS IN BRAZIL

Salmonella is the most common etiological agent of cases and outbreaks of foodborne diarrheal illnesses. The emergence and spread of Salmonella spp., which has become multi-drug resistant and potentially more pathogenic, have increased the concern with this pathogen. In this study, 237 Salmonella spp., associated or not with foodborne salmonellosis in Brazil, belonging mainly to serotype Enteritidis, were tested for antimicrobial susceptibility and the presence of the virulence genes spvC, invA, sefA and pefA. Of the isolates, 46.8% were sensitive to all antimicrobials and 51.9% were resistant to at least one antimicrobial agent. Resistance to more than one antimicrobial agent was observed in 10.5% of the strains. The highest rates of resistance were observed for streptomycin (35.9%) and nalidixic acid (16.9%). No strain was resistant to cefoxitin, cephalothin, cefotaxime, amikacin, ciprofloxacin and imipenem. The invA gene was detected in all strains. Genes spvC and pefA were found in 48.1% and 44.3% of strains, respectively. The gene sefA was detected in 31.6% of the strains and only among S. Enteritidis. Resistance and virulence determinants were detected in Salmonella strains belonging to several serotypes. The high rates of antibiotic-resistance in strains isolated from poultry products demonstrate the potential risk associated with the consumption of these products and the need to ensure good food hygiene practices from farm to table to reduce the spread of pathogens relevant to public health

Multiancestry analysis of the HLA locus in Alzheimer’s and Parkinson’s diseases uncovers a shared adaptive immune response mediated by HLA-DRB1*04 subtypes

Across multiancestry groups, we analyzed Human Leukocyte Antigen (HLA) associations in over 176,000 individuals with Parkinson’s disease (PD) and Alzheimer’s disease (AD) versus controls. We demonstrate that the two diseases share the same protective association at the HLA locus. HLA-specific fine-mapping showed that hierarchical protective effects of HLA-DRB1*04 subtypes best accounted for the association, strongest with HLA-DRB1*04:04 and HLA-DRB1*04:07, and intermediary with HLA-DRB1*04:01 and HLA-DRB1*04:03. The same signal was associated with decreased neurofibrillary tangles in postmortem brains and was associated with reduced tau levels in cerebrospinal fluid and to a lower extent with increased Aβ42. Protective HLA-DRB1*04 subtypes strongly bound the aggregation-prone tau PHF6 sequence, however only when acetylated at a lysine (K311), a common posttranslational modification central to tau aggregation. An HLA-DRB1*04-mediated adaptive immune response decreases PD and AD risks, potentially by acting against tau, offering the possibility of therapeutic avenues

Global, regional, and national life expectancy, all-cause mortality, and cause-specific mortality for 249 causes of death, 1980-2015 : a systematic analysis for the Global Burden of Disease Study 2015

Background Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specific mortality for 249 causes in 195 countries and territories from 1980 to 2015. These results informed an in-depth investigation of observed and expected mortality patterns based on sociodemographic measures. Methods We estimated all-cause mortality by age, sex, geography, and year using an improved analytical approach originally developed for GBD 2013 and GBD 2010. Improvements included refinements to the estimation of child and adult mortality and corresponding uncertainty, parameter selection for under-5 mortality synthesis by spatiotemporal Gaussian process regression, and sibling history data processing. We also expanded the database of vital registration, survey, and census data to 14 294 geography-year datapoints. For GBD 2015, eight causes, including Ebola virus disease, were added to the previous GBD cause list for mortality. We used six modelling approaches to assess cause-specific mortality, with the Cause of Death Ensemble Model (CODEm) generating estimates for most causes. We used a series of novel analyses to systematically quantify the drivers of trends in mortality across geographies. First, we assessed observed and expected levels and trends of cause-specific mortality as they relate to the Socio-demographic Index (SDI), a summary indicator derived from measures of income per capita, educational attainment, and fertility. Second, we examined factors affecting total mortality patterns through a series of counterfactual scenarios, testing the magnitude by which population growth, population age structures, and epidemiological changes contributed to shifts in mortality. Finally, we attributed changes in life expectancy to changes in cause of death. We documented each step of the GBD 2015 estimation processes, as well as data sources, in accordance with Guidelines for Accurate and Transparent Health Estimates Reporting (GATHER). Findings Globally, life expectancy from birth increased from 61.7 years (95% uncertainty interval 61.4-61.9) in 1980 to 71.8 years (71.5-72.2) in 2015. Several countries in sub-Saharan Africa had very large gains in life expectancy from 2005 to 2015, rebounding from an era of exceedingly high loss of life due to HIV/AIDS. At the same time, many geographies saw life expectancy stagnate or decline, particularly for men and in countries with rising mortality from war or interpersonal violence. From 2005 to 2015, male life expectancy in Syria dropped by 11.3 years (3.7-17.4), to 62.6 years (56.5-70.2). Total deaths increased by 4.1% (2.6-5.6) from 2005 to 2015, rising to 55.8 million (54.9 million to 56.6 million) in 2015, but age-standardised death rates fell by 17.0% (15.8-18.1) during this time, underscoring changes in population growth and shifts in global age structures. The result was similar for non-communicable diseases (NCDs), with total deaths from these causes increasing by 14.1% (12.6-16.0) to 39.8 million (39.2 million to 40.5 million) in 2015, whereas age-standardised rates decreased by 13.1% (11.9-14.3). Globally, this mortality pattern emerged for several NCDs, including several types of cancer, ischaemic heart disease, cirrhosis, and Alzheimer's disease and other dementias. By contrast, both total deaths and age-standardised death rates due to communicable, maternal, neonatal, and nutritional conditions significantly declined from 2005 to 2015, gains largely attributable to decreases in mortality rates due to HIV/AIDS (42.1%, 39.1-44.6), malaria (43.1%, 34.7-51.8), neonatal preterm birth complications (29.8%, 24.8-34.9), and maternal disorders (29.1%, 19.3-37.1). Progress was slower for several causes, such as lower respiratory infections and nutritional deficiencies, whereas deaths increased for others, including dengue and drug use disorders. Age-standardised death rates due to injuries significantly declined from 2005 to 2015, yet interpersonal violence and war claimed increasingly more lives in some regions, particularly in the Middle East. In 2015, rotaviral enteritis (rotavirus) was the leading cause of under-5 deaths due to diarrhoea (146 000 deaths, 118 000-183 000) and pneumococcal pneumonia was the leading cause of under-5 deaths due to lower respiratory infections (393 000 deaths, 228 000-532 000), although pathogen-specific mortality varied by region. Globally, the effects of population growth, ageing, and changes in age-standardised death rates substantially differed by cause. Our analyses on the expected associations between cause-specific mortality and SDI show the regular shifts in cause of death composition and population age structure with rising SDI. Country patterns of premature mortality (measured as years of life lost [YLLs]) and how they differ from the level expected on the basis of SDI alone revealed distinct but highly heterogeneous patterns by region and country or territory. Ischaemic heart disease, stroke, and diabetes were among the leading causes of YLLs in most regions, but in many cases, intraregional results sharply diverged for ratios of observed and expected YLLs based on SDI. Communicable, maternal, neonatal, and nutritional diseases caused the most YLLs throughout sub-Saharan Africa, with observed YLLs far exceeding expected YLLs for countries in which malaria or HIV/AIDS remained the leading causes of early death. Interpretation At the global scale, age-specific mortality has steadily improved over the past 35 years; this pattern of general progress continued in the past decade. Progress has been faster in most countries than expected on the basis of development measured by the SDI. Against this background of progress, some countries have seen falls in life expectancy, and age-standardised death rates for some causes are increasing. Despite progress in reducing age-standardised death rates, population growth and ageing mean that the number of deaths from most non-communicable causes are increasing in most countries, putting increased demands on health systems.

Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks, 1990-2015: a systematic analysis for the Global Burden of Disease Study 2015

Forouzanfar MH, Afshin A, Alexander LT, et al. Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks, 1990-2015: a systematic analysis for the Global Burden of Disease Study 2015. LANCET. 2016;388(10053):1659-1724.Background The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. Methods We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defined criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factors-the summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted cause-specific DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI). Findings Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57.8% (95% CI 56.6-58.8) of global deaths and 41.2% (39.8-42.8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211.8 million [192.7 million to 231.1 million] global DALYs), smoking (148.6 million [134.2 million to 163.1 million]), high fasting plasma glucose (143.1 million [125.1 million to 163.5 million]), high BMI (120.1 million [83.8 million to 158.4 million]), childhood undernutrition (113.3 million [103.9 million to 123.4 million]), ambient particulate matter (103.1 million [90.8 million to 115.1 million]), high total cholesterol (88.7 million [74.6 million to 105.7 million]), household air pollution (85.6 million [66.7 million to 106.1 million]), alcohol use (85.0 million [77.2 million to 93.0 million]), and diets high in sodium (83.0 million [49.3 million to 127.5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient deficiencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa. Interpretation Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden. Copyright (C) The Author(s). Published by Elsevier Ltd

Conversion of Lignocelluloses into bioethanol utilizing hardwood sawdust used for pleurotus ostreatus cultivation

In this study, hardwood sawdust substrate used for oyster mushroom cultivation was utilized as raw material for ethanol production. The cultivation of oyster mushroom was used as a pretreatment to degrade the lignin content of the raw material. The lignocelluloses in the raw material were converted to ethanol by concentrated sulfuric acid hydrolysis for an hour and simple fermentation for four days. The same experimentation process was also done using pure hardwood sawdust (uncultivated with oyster mushroom) in order to compare whether the oyster mushroom gave significant changes in sugar and ethanol yield. The hydrolysis process was optimized and the parameters varied were temperature, biomass concentration, and acid concentration. Taguchi Array was used to determine the conditions for the 9 runs of the experimentation. The highest sugar and ethanol concentration were both obtained at run 1 (121C, 15% (v/v) acid concentration and 20% (w/v) biomass concentration). Comparing the results for sawdust substrate used for oyster mushroom cultivation and pure sawdust substrate, the sugar and ethanol concentration were higher for pure sawdust. The oyster mushroom may have helped in the degradation of lignin in the sawdust substrate cultivated with mushroom but also might have degraded some of the celluloses and hemicelluloses that affected the amount of lignocelluloses converted to fermentable sugars. The effect of the activity of the natural enzyme released by oyster mushroom had been proven that this white-rot fungi releases enzymes that can completely degrade the lignocellulosic material. It degrades lignin but at the same time releases enzymes that degrades hemicelluloses and cellulose such as the enzyme cellulase. The optimum conditions depend upon the desired output. If a higher concentration of sugar, sugar yield percent, ethanol concentration for both raw materials, and high ethanol yield percent for the cultivated hardwood sawdust substrate used in growing mushroom would be desired, then based on the experiment the conditions for hydrolysis process can be performed at 121C, 15% (v/v) acid concentration and 20% (w/v) biomass concentration. But if a higher ethanol yield for the pure hardwood sawdust would be desired then the conditions for the hydrolysis can be performed at 121C, 15% (v/v) acid concentration and 10% (w/v) biomass concentration. In conclusion, having a high concentration is better than having good yield percent considering that using pure hardwood sawdust gave a higher concentration than hardwood sawdust used in cultivating oyster mushrooms. The effect of the mushroom had degraded the lignocellulosic component that had caused a trade-off in which the sawdust was instead used in producing oyster mushroom than having high ethanol concentration. In ethanol production having a high concentration in terms of its purity is better to achieve rather than having a good yield percent making the pure hardwood sawdust better to use

Molecular-based detection of pathogenic Listeria sp. in Philippine raw carabao\u27s milk and white cheese

This study was conducted to detect the presence of pathogenic Listeria species in locally produced white cheese (quesong puti) and raw carabao’s milk samples from Laguna, Nueva Ecija, Bulacan, Rizal, Lucena City, and Makati City, Philippines using phenotypic and molecular analyses. Out of 208 initial isolates obtained from 31 dairy product samples, 118 isolates were preliminarily considered presumptive Listeria species based on established culture-based detection methods. Further phenotypic tests and growth efficiency assessment using highly selective Polymyxin Acriflavine Lithium chloride Ceftazidime Aesculin Mannitol (PALCAM) agar narrowed them down to only five putative isolates. However, the Polymerase Chain Reaction (PCR) analysis using the primer pairs Lis and LL1/LL4 for the listeriolysin O gene and iap for the invasion-associated protein gene yielded negative results for the potentially pathogenic Listeria spp., except for the ARKPC49 isolate. The isolate, which was identified as Providencia sp. through 16s ribosomal DNA (rDNA) sequence analysis, was found to have variant PCR amplicons. Cluster analysis also confirmed its unrelatedness to Listeria spp. Four other isolates (e.g., LKPC48, LC3C37, LC2C29, and LC2C42) which exhibited gray-green colonies with a black halo on PALCAM Agar were identified as Corynebacterium vitarumen. Thus, the results confirmed the absence of pathogenic Listeria spp. and highlighted the need for molecular methods to supplement cultural methods in detecting pathogenic Listeria spp. from dairy products
