The Influence of Religious Beliefs and Ethnic Diversity on the HIV/AIDS Epidemic in Latin America and Muslim Countries
In the absence of substantial differences in the growth rates of per capita GDP across countries, what are the factors that explain the rapid spread of the HIV infection within a nation? This is an empirical question that needs to be explained. In order to elucidate the correlation between HIV prevalence and economic growth in a sample of 74 low- and middle-income countries, being Muslim and ethnic diversity can be used as main instruments to produce estimates of the effect of HIV prevalence on the growth rate of real GDP per capita that are not affected by the presence of simultaneity.HIV/AIDS, economic growth, religious belief, ethnic diversity, Latin America, Muslim Countries
ECO 167 Introduction to Microeconomics
The purpose of this course is to help the student acquire a greater degree of economic literacy to better understand the functioning of our social system. Economics is a technical discipline with its own specialized vocabulary and methodology and is also a subject where informed positions widely diverge. The student is expected to understand as well as to analyze complex social and economic settings. This course starts from how supply and demand cause prices changes leading different market equilibrium. We will examine how market economies are efficient, and the way governments can make our economy less or more efficient. We will delve behind the supply curve to see how firms choose their production levels to maximize profits, culminating in the model of perfect competition. We will look at market failures such as imperfect competition (monopoly and oligopoly) and externalities
COVIDâ19, Race/Ethnicity, and Age: the Role of Telemedicine to Close the Gaps on Health Disparities
The novel COVID-19 outbreak is a major public health challenge that quickly turned into an economic recession of great proportions. This pandemic poses a trade-off between health and the economy where social distancing, quarantines, and isolation shut down demand and supply chains across the USA. This paper analyzes the impact of COVID-19 on illness and death among older adults and communities of color with low socioeconomic status in New York City. To achieve this goal, fractional logit models are used to capture changes in the novel virusâ morbidity and mortality rates at the neighborhood level. Median income, race/ethnicity, age, household crowding, and socially interactive employment explained the disproportionate exposure and fatalities across the city. We also employ a variable related to telehealth/telemedicine to sustain that technology goods along with government intervention as a provider of social goods can ameliorate existing health disparities. There is a need for evidence-based data on the economic costs and social benefits of COVID-19 relief programs
The Cost Effectiveness of Mental Health Treatment in the Lifetime of Older Adults with HIV in New York City: A Markov Approach
Background
There are noticeable gaps in knowledge regarding the cost and effectiveness of integrated medical and behavioral services for older adults with HIV. Their lifespan is close to the populationâs level but their quality of life has sharply declined due to depression and substance use. Mental health disorders are widespread among an aging population with HIV. Objective The aim of this study was to build a decision analytic model to evaluate medical interventions with and without mental health treatment using primary data of 139 older adults with HIV and health outcomes from the literature.
Methods
We tracked the progression of depression and cumulative deaths among older adults with HIV using a Markov model with 50 annual cycles through three health states. Deterministic and probabilistic sensitivity analyses addressed uncertainty in estimating the parameters and around the modelâs assumptions.
Results An integrated medical and behavioral care system is cost effective at a willingness to pay of 516,452 and the incremental effectiveness was 38.8 quality-adjusted life-years (QALY), with an incremental cost-effectiveness ratio of $13,316 per QALY.
Conclusions
Appropriate and efficacious referrals to integrated medical + behavioral services, either in the same facility or connected to their primary care doctor, are instrumental to reverse loses in quality of life and avoid premature death. If mental health is left unattended, HIV would progress, causing declines in quality of life and ultimately triggering premature death. Reliable data on the cost and effectiveness of different types of HIV integrated services are needed
An Economic Analysis of the Environmental Impact of PM2.5 Exposure on Health Status in Three Northwestern Mexican Cities
Introduction: This study provides an economic assessment of the health effects due to exposure to particulate matter PM2.5 in three medium-size cities of northwestern Mexico: Los Mochis, Culiacan and MazatlĂĄn. People in these cities are exposed to high pollutant concentrations that exceed limits suggested in domestic and international guidelines. PM2.5 is an air contaminant negatively associated with peopleâs health when is highly concentrated in the atmosphere; its diameter is below 2.5 ”m and causes the air to appear hazy when levels are elevated. To account for the economic impact of air pollution, a Health Impact Assessment (HIA) was used by the means of the European Aphekom Project. We figured the cost-savings of complying with current environmental standards and computed gains in life expectancy, total avoidable premature mortality, preventable cardiovascular disease, and the economic costs of air pollution related to PM2.5. A formal analysis of air pollution epidemiology is not pursued in this paper. Results: The cost of reducing PM2.5 pollution associated with negative health outcomes was based on two different scenarios: Official Mexican Standard (NOM, Spanish acronym) and World Health Organization (WHO) environmental standards. The mean PM2.5 concentrations in 2017 were 22.8, 22.4 and 14.1 ”g/m3 for Los Mochis, MazatlĂĄn and Culiacan, respectively. Conclusions: The mean avoidable mortality for all causes associated to PM2.5 exposure in these cities was 638 for the NOM scenario (i.e., with a reduction to 12 ”g/m3) compared to 739 for the WHO scenario (reduction to 10 ”g/m3). Complying with the WHO guideline of 10 ”g/m3 in annual PM2.5 mean would add up to 15 months of life expectancy at age 30, depending on the city. The mean economic cost per year of the PM2.5 effects on human life in these three cities was USD 600 million (NOM scenario) and USD 695 million (WHO scenario). Thus, effective public health and industrial policy interventions to improve air quality are socially advantageous and cost-saving to promote better health.S
Still a Hard-to-Reach Population? Using Social Media to Recuit Latino Gay Couples for an HIV Intervention Adaptation Study
Background
Online social networking use has increased rapidly among African American and Latino men who have sex with men (MSM), making it important to understand how these technologies can be used to reach, retain, and maintain individuals in care and promote health wellness. In particular, the Internet is increasingly recognized as a platform for health communication and education. However, little is known about how primarily Spanish-speaking populations use and engage with each other through social media platforms.
Objective
We aimed to recruit eligible couples for a study to adapt âConnect ân Uniteâ (an HIV prevention intervention initially created for black gay couples) for Spanish-speaking Latino gay couples living in New York City.
Methods
In order to successfully design and implement an effective social media recruitment campaign to reach Spanish-speaking Latino gay couples for our ongoing âLatinos en Parejaâ study, our community stakeholders and research team used McGuireâs communication/persuasion matrix. The matrix guided our research, specifically each marketing âchannelâ, targeted âmessageâ, and target population or âreceiverâ. We developed a social media recruitment protocol and trained our research staff and stakeholders to conduct social media recruitment.
Results
As a result, in just 1 month, we recruited all of our subjects (N=14 couples, that is, N=28 participants) and reached more than 35,658 participants through different channels. One of the major successes of our social media recruitment campaign was to build a strong stakeholder base that became involved early on in all aspects of the research processâfrom pilot study writing and development to recruitment and retention. In addition, the variety of âmessagesâ used across different social media platforms (including Facebook, the âLatinos en Parejaâ study website, Craigslist, and various smartphone applications such as Grindr, SCRUFF, and Jackâd) helped recruit Latino gay couples. We also relied on a wide range of community-based organizations across New York City to promote the study and build in the social media components.
Conclusions
Our findings highlight the importance of incorporating communication technologies into the recruitment and engagement of participants in HIV interventions. Particularly, the success of our social media recruitment strategy with Spanish-speaking Latino MSM shows that this population is not particularly âhard to reachâ, as it is often characterized within public health literature
Role of Aramchol in steatohepatitis and fibrosis in mice.
Nonalcoholic steatohepatitis (NASH) is the advanced form of nonalcoholic fatty liver disease (NAFLD) which sets the stage for further liver damage. The mechanism for the progression of NASH involves multiple parallel hits including oxidative stress, mitochondrial dysfunction, inflammation and others. Manipulation of any of these pathways may be an approach to prevent NASH development and progression. Aramchol (arachidyl-amido cholanoic acid) is presently in a phase IIb NASH study. The aim of this study was to investigate Aramchol's mechanism of action and its effect on fibrosis using the methionine- and choline-deficient (MCD) diet model of NASH. We collected liver and serum from mice fed a MCD diet containing 0.1% methionine (0.1MCD) for four weeks, which developed steatohepatitis and fibrosis, as well as mice receiving a control diet; the metabolomes and proteomes were determined. 0.1MCD fed mice were given Aramchol (5mg/kg/day for the last 2 weeks); liver samples were analyzed histologically. Aramchol administration reduced features of steatohepatitis and fibrosis in 0.1MCD fed mice. Aramchol downregulated stearoyl-CoA desaturase 1 (SCD1), a key enzyme involved in triglyceride biosynthesis whose loss enhances fatty acid ÎČ-oxidation. Aramchol increased the flux through the transsulfuration pathway, leading to a rise in glutathione (GSH) and GSH/GSSG ratio, the main cellular antioxidant that maintains intracellular redox status. Comparison of serum metabolomic pattern between 0.1MCD fed mice and NAFLD patients showed a substantial overlap. Conclusions:Aramchol treatment improved steatohepatitis and fibrosis by 1) decreasing SCD1, and 2) increasing the flux through the transsulfuration pathway maintaining cellular redox homeostasis. We also demonstrated that the 0.1MCD model resembles the metabolic phenotype observed in about 50% of NAFLD patients, which supports the potential use of Aramchol in NASH treatment
