Live 12:00 – 1:00 P.M Mediterranean Diet and Lifestyle: A Symposium on Diet and Human Health : October 19, 2018
Reporter: Stephen J. Williams, Ph.D.
12.00 The Italian Mediterranean Diet as a Model of Identity of a People with a Universal Good to Safeguard Health?
Prof. Antonino De Lorenzo, MD, PhD.
Director of the School of Specialization in Clinical Nutrition, University of Rome “Tor Vergata”
It is important to determine how our bodies interacts with the environment, such as absorption of nutrients.
Studies shown here show decrease in life expectancy of a high sugar diet, but the quality of the diet, not just the type of diet is important, especially the role of natural probiotics and phenolic compounds found in the Mediterranean diet.
The WHO report in 2005 discusses the unsustainability of nutrition deficiencies and suggest a proactive personalized and preventative/predictive approach of diet and health.
Most of the noncommunicable diseases like CV (46%) cancer 21% and 11% respiratory and 4% diabetes could be prevented and or cured with proper dietary approaches
Italy vs. the US diseases: in Italy most disease due to environmental contamination while US diet plays a major role
The issue we are facing in less than 10% of the Italian population (fruit, fibers, oils) are not getting the proper foods, diet and contributing to as we suggest 46% of the disease
The Food Paradox: 1.5 billion are obese; we notice we are eating less products of quality and most quality produce is going to waste;
growing BMI and junk food: our studies are correlating the junk food (pre-prepared) and global BMI
modern diet and impact of human health (junk food high in additives, salt) has impact on microflora
Western Diet and Addiction: We show a link (using brain scans) showing correlation of junk food, sugar cravings, and other addictive behaviors by affecting the dopamine signaling in the substantia nigra
developed a junk food calculator and a Mediterranean diet calculator
the intersection of culture, food is embedded in the Mediterranean diet; this is supported by dietary studies of two distinct rural Italian populations (one of these in the US) show decrease in diet
Impact of diet: have model in Germany how this diet can increase health and life expectancy
from 1950 to present day 2.7 unit increase in the diet index can increase life expectancy by 26%
so there is an inverse relationship with our index and breast cancer
Environment and metal contamination and glyphosate: contribution to disease and impact of maintaining the healthy diet
huge problem with use of pesticides and increase in celiac disease
Cancer as a disease of the environment. Weinberg’s hallmarks of Cancer reveal how environment and epigenetics can impact any of these hallmarks.
Epigenetic effects
gene gatekeepers (Rb and P53)
DNA repair and damage stabilization
Heavy Metals and Dioxins:( alterations of the immune system as well as epigenetic regulations)
Asbestos and Mesothelioma: they have demonstrated that p53 can be involved in development of mesothelioma as reactivating p53 may be a suitable strategy for therapy
Diet, Tomato and Cancer
looked at tomato extract on p53 function in gastric cancer: tomato extract had a growth reduction effect and altered cell cycle regulation and results in apoptosis
RBL2 levels are increased in extract amount dependent manner so data shows effect of certain tomato extracts of the southern italian tomato ( )
Antonio Giordano: we tested whole extracts of almost 30 different varieties of tomato. The tomato variety with highest activity was near Ravela however black tomatoes have shown high antitumor activity. We have done a followup studies showing that these varieties, if grow elsewhere lose their antitumor activity after two or three generations of breeding, even though there genetics are similar. We are also studying the effects of different styles of cooking of these tomatoes and if it reduces antitumor effect

There Are Two Americas Now: One With a B.A. and One Without’
Carol Graham, a senior fellow at Brookings, described the erosion of economic and social status for whites without college degrees in a 2021 paper:
From 2005 to 2019, an average of 70,000 Americans died annually from deaths of despair (suicide, drug overdose, and alcohol poisoning). These deaths are concentrated among less than college educated middle-aged whites, with those out of the labor force disproportionately represented. Low-income minorities are significantly more optimistic than whites and much less likely to die of these deaths. This despair reflects the decline of the white working class. Counties with more respondents reporting lost hope in the years before 2016 were more likely to vote for Trump.
A 2010 Pew Research Center study that examined the effects of the Great Recession on Black and white Americans reported that Black Americans consistently suffered more in terms of unemployment, work cutbacks and other measures, but remained far more optimistic about the future than whites. Twice as many Black as white Americans were forced during the 2008 recession to work fewer hours, to take unpaid leave or switch to part-time, and Black unemployment rose from 8.9 to 15.5 percent from April 2007 to April 2009, compared with an increase from 3.7 to 8 percent for whites.
Despite experiencing more hardship, 81 percent of Black Americans agreed with the statement “America will always continue to be prosperous and make economic progress,” compared with 59 percent of whites; 45 percent of Black Americans said the country was still in recession compared with 57 percent of whites
In “Trends in Extreme Distress in the United States, 1993-2019,” David G. Blanchflower and Andrew J. Oswald, economists at Dartmouth and the University of Warwick in Britain, note that “the proportion of the U.S. population in extreme distress rose from 3.6 percent in 1993 to 6.4 percent in 2019. Among low-education midlife white persons, the percentage more than doubled, from 4.8 percent to 11.5 percent.”
In her 2020 paper, “Trends in U.S. Working-Age Non-Hispanic White Mortality: Rural-Urban and Within-Rural Differences,” Shannon M. Monnat, a professor of sociology at Syracuse University’s Maxwell School, explained that “between 1990-92 and 2016-18, the mortality rates among non-Hispanic whites increased by 9.6 deaths per 100,000 population among metro males and 30.5 among metro females but increased by 70.1 and 65.0 among nonmetro (rural and exurban) males and females, respectively.”
Three economists, David Autor, David Dorn and Gordon Hanson of M.I.T., the University of Zurich and Harvard, reported in their 2018 paper, “When Work Disappears: Manufacturing Decline and the Falling Marriage Market Value of Young Men,” on the debilitating consequences for working-class men of the “China shock”
There is some evidence that partisanship correlates with mortality rates.
Anne Case wrote in her email, that the United States is fast approaching a point where
Education divides everything, including connection to the labor market, marriage, connection to institutions (like organized religion), physical and mental health, and mortality. It does so for whites, Blacks and Hispanics. There has been a profound (not yet complete) convergence in life expectancy by education. There are two Americas now: one with a B.A. and one without.
Aside from the decline in sperm counts, growing numbers of sperm appear defective — there’s a boom in two-headed sperm — while others loll aimlessly in circles, rather than furiously swimming in pursuit of an egg. And infants who have had greater exposures to a kind of endocrine disruptor called phthalates have smaller penises, Swan found.
Recent studies concluded via rigorous and comprehensive analysis found that Sperm Count (SC) declined 52.4% between 1973 and 2011 among unselected men from western countries, with no evidence of a ‘leveling off’ in recent years. Declining mean SC implies that an increasing proportion of men have sperm counts below any given threshold for sub-fertility or infertility. The high proportion of men from western countries with concentration below 40 million/ml is particularly concerning given the evidence that SC below this threshold is associated with a decreased monthly probability of conception.
1.Temporal trends in sperm count: a systematic review and meta-regression analysis
Hagai Levine, Niels Jørgensen, Anderson Martino‐Andrade, Jaime Mendiola, Dan Weksler-Derri, Irina Mindlis, Rachel Pinotti, Shanna H Swan. Human Reproduction Update, July 25, 2017, doi:10.1093/humupd/dmx022.
4. Long, mysterious strips of RNA contribute to low sperm count – Long non-coding RNAs can be added to the group of possible non-structural effects, possibly epigenetic, that might regulate sperm counts.
Thus, we postulated that some lncRNAs may also impact mammalian spermatogenesis and fertility. In this study, we identified a dynamic expression pattern of lncRNAs during murine spermatogenesis. Importantly, we identified a subset of lncRNAs and very few mRNAs that appear to escape meiotic sex chromosome inactivation (MSCI), an epigenetic process that leads to the silencing of the X- and Y-chromosomes at the pachytene stage of meiosis. Further, some of these lncRNAs and mRNAs show strong testis expression pattern suggesting that they may play key roles in spermatogenesis. Lastly, we generated a mouse knock out of one X-linked lncRNA, Tslrn1 (testis-specific long non-coding RNA 1), and found that males carrying a Tslrn1 deletion displayed normal fertility but a significant reduction in spermatozoa. Our findings demonstrate that dysregulation of specific mammalian lncRNAs is a novel mechanism of low sperm count or infertility, thus potentially providing new biomarkers and therapeutic strategies.
This article presents two perspectives on the potential effects of Sperm Count decline.
One Perspective identifies Epigenetics and male well-being conditions
as a potential explanation to the Sperm Count decline, and
as evidence for decline in White male longevity in certain geographies in the US since the mid 80s.
The other Perspective, evaluates if Sperm Count Decline would have or would not have a significant long term effects on Population Evolution and Demography.
The Voice of Prof. Marc Feldman, Stanford University – Long term significance of Sperm Count Decline on Population Evolution and Demography
Poor sperm count appears to be associated with such demographic statistics as life expectancy (1), infertility (2), and morbidity (3,4). The meta-analysis by Levine et al. (5) focuses on the change in sperm count of men from North America, Europe, Australia, and New Zealand, and shows a more than 50% decline between 1973 and 2011. Although there is no analysis of potential environmental or lifestyle factors that could contribute to the estimated decline in sperm count, Levine et al. speculate that this decline could be a signal for other negative changes in men’s health.
Because this study focuses mainly on Western men, this remarkable decline in sperm count is difficult to associate with any change in actual fertility, that is, number of children born per woman. The total fertility rate in Europe, especially Italy, Spain, and Germany, has slowly declined, but age at first marriage has increased at the same time, and this increase may be more due to economic factors than physiological changes.
Included in Levine et al.’s analysis was a set of data from “Other” countries from South America, Asia, and Africa. Sperm count in men from these countries did not show significant trends, which is interesting because there have been strong fertility declines in Asia and Africa over the same period, with corresponding increases in life expectancy (once HIV is accounted for).
What can we say about the evolutionary consequences for humans of this decrease? The answer depends on the minimal number of sperm/ml/year that would be required to maintain fertility (per woman) at replacement level, say 2.1 children, over a woman’s lifetime. Given the smaller number of ova produced per woman, a change in the ovulation statistics of women would be likely to play a larger role in the total fertility rate than the number of sperm/ejaculate/man. In other words, sperm count alone, absent other effects on mortality during male reproductive years, is unlikely to tell us much about human evolution.
Further, the major declines in fertility over the 38-year period covered by Levine et al. occurred in China, India, and Japan. Chinese fertility has declined to less than 1.5 children per woman, and in Japan it has also been well below 1.5 for some time. These declines have been due to national policies and economic changes, and are therefore unlikely to signal genetic changes that would have evolutionary ramifications. It is more likely that cultural changes will continue to be the main drivers of fertility change.
The fastest growing human populations are in the Muslim world, where fertility control is not nearly as widely practiced as in the West or Asia. If this pattern were to continue for a few more generations, the cultural evolutionary impact would swamp any effects of potentially declining sperm count.
On the other hand, if the decline in sperm count were to be discovered to be associated with genetic and/or epigenetic phenotypic effects on fetuses, newborns, or pre-reproductive humans, for example, due to stress or obesity, then there would be cause to worry about long-term evolutionary problems. As Levine et al. remark, “decline in sperm count might be considered as a ‘canary in the coal mine’ for male health across the lifespan”. But to date, there is little evidence that the evolutionary trajectory of humans constitutes such a “coal mine”.

Psycho-Social Effects of Poverty, Unemployment and Epigenetics on Male Well-being, Physiological Conditions as POTENTIAL effects on Sperm Quality and Quantity and Evidence of its effects on Male Longevity
The IMPACT of Well-being, Stress induced by Worry, Pain, Perception of Hope related to Employment and Lack of employment on deterioration of Physiological Conditions as evidence by Decrease Longevity
In recent work based on our well-being metrics in the Gallup polls and on the mortality data from the Centers for Disease Control and Prevention, we find a robust association between lack of hope (and high levels of worry) among poor whites and the premature mortality rates, both at the individual and metropolitan statistical area (MSA) levels. Yet we also find important differences across places. Places come with different economic structures and identities, community traits, physical environments and much more. In the maps below, we provide a visual picture of the differences in in hope for the future, worry, and pain across race-income cohorts across U.S. states. We attempted to isolate the specific role of place, controlling for economic, socio-demographic, and other variables.
One surprise is the low level of optimism and high level of worry in the minority dense and generally “blue” state of California, and high levels of pain and worry in the equally minority dense and “blue” states of New York and Massachusetts. High levels of income inequality in these states may explain these patterns, as may the nature of jobs that poor minorities hold.
We cannot answer many questions at this point. What is it about the state of Washington, for example, that is so bad for minorities across the board? Why is Florida so much better for poor whites than it is for poor minorities? Why is Nevada “good” for poor white optimism but terrible for worry for the same group? One potential issue—which will enter into our future analysis—is racial segregation across places. We hope that the differences that we have found will provoke future exploration. Readers of this piece may have some contributions of their own as they click through the various maps, and we welcome their input. Better understanding the role of place in the “crisis” of despair facing our country is essential to finding viable solutions, as economic explanations, while important, alone are not enough.
There has been a genuine decline in semen quality over the past 50 years. There is lot of controversy about this as there are limitations in studies that have attempted to address it. Sperm count is of considerable public health importance for several reasons. First, sperm count is closely linked to male fecundity and is a crucial component of semen analysis, the first step to identify male factor infertility.
Reduced sperm count is associated with cryptorchidism, hypospadias and testicular cancer. It may be associated with multiple environmental influences, including endocrine disrupting chemicals, pesticides, heat and lifestyle factors, including diet, stress, smoking and BMI. Therefore, sperm count may sensitively reflect the impacts of the modern environment on male health throughout the life span.
This study provided a systematic review and meta-regression analysis of recent trends in sperm counts as measured by sperm concentration (SC) and total sperm count (TSC), and their modification by fertility and geographic group. Analyzing trends by birth cohorts instead of year of sample collection may aid in assessing the causes of the decline (prenatal or in adult life) but was not feasible owing to lack of information.
This rigorous and comprehensive analysis found that SC declined 52.4% between 1973 and 2011 among unselected men from western countries, with no evidence of a ‘leveling off’ in recent years. Declining mean SC implies that an increasing proportion of men have sperm counts below any given threshold for sub-fertility or infertility. The high proportion of men from western countries with concentration below 40 million/ml is particularly concerning given the evidence that SC below this threshold is associated with a decreased monthly probability of conception.
Declines in sperm count have implications beyond fertility and reproduction. The decline reported in this study is consistent with reported trends in other male reproductive health indicators, such as testicular germ cell tumors, cryptorchidism, onset of male puberty and total testosterone levels. The public health implications are even wider. Recent studies have shown that poor sperm count is associated with overall morbidity and mortality. While the current study is not designed to provide direct information on the causes of the observed declines, sperm count has been plausibly associated with multiple environmental (including unwanted chemical exposure in alarming levels) and lifestyle influences, both prenatally and in adult life. In particular, endocrine disruption from chemical exposures or maternal smoking during critical windows of male reproductive development may play a role in prenatal life, while lifestyle changes and exposure to pesticides may play a role in adult life.
These findings strongly suggest a significant decline in male reproductive health, which has serious implications beyond fertility concerns. Research on causes and implications of this decline is urgently needed.

The Rutgers Global Health Institute, part of Rutgers Biomedical and Health Sciences, Rutgers University, New Brunswick, New Jersey – A New Venture Designed to Improve Health and Wellness Globally
Author: Gail S. Thornton, M.A.
Co-Editor: The VOICES of Patients, Hospital CEOs, HealthCare Providers, Caregivers and Families: Personal Experience with Critical Care and Invasive Medical Procedures
The newly formed Rutgers Global Health Institute, part of Rutgers Biomedical and Health Sciences (RBHS) of Rutgers University, New Brunswick, New Jersey (http://rbhs.rutgers.edu/), represents a new way of thinking by providing positive health outcomes to potential patients around the world affected by disease and/or by a negative environmental impact. The goal of the Institute is three-fold:
to improve the health and wellness of individuals and populations around the world,
to create a healthier world through innovation, engineering, and technology, and
to educate involved citizens and effective leaders in global health.
Richard G. Marlink, M.D., a former Harvard University professor recognized internationally for research and leadership in the fight against AIDS, was recently appointed as the inaugural Henry Rutgers Professor of Global Health and Director of the Rutgers Global Health Institute.
The Rutgers Global Health Institute was formed last year after research by the University into the most significant health issues affecting under-served and under-developed populations. While conducting research for its five-year strategic plan, the RBHS looked for bold and ambitious ways that they could take advantage of the changing health care environment and band together to tackle the world’s leading health and environmental causes, contributing to the betterment of society. One of the results was the formation of the Rutgers Global Health Institute, supporting cross-functionally Rutgers faculty, scientists, and clinicians who represent the best in their respective fields of health innovation, research and patient care related to global health.
More broadly, the RBHS, created in 2013, is one of the nation’s leading – and largest — academic health centers that provides health care education, research and clinical service and care. It is an umbrella organization that encompasses eight schools – Ernest Mario School of Pharmacy, Graduate School of Biomedical Sciences, New Jersey Medical School, Robert Wood Johnson Medical School, Rutgers School of Dental Medicine, School of Health Professions, School of Nursing and School of Public Health.
In addition, the RBHS encompasses six centers and institutes that provide cancer treatment and research, neuroscience, advanced biotechnology and medicine, environmental and occupational health and health care policy and aging research. Those centers and institutes are the Brain Health Institute, Center for Advanced Biotechnology and Medicine, Environmental and Occupational Health Sciences Institute, Institute for Health, Health Care Policy and Aging Research, Rutgers Cancer Institute of New Jersey, and Rutgers Institute for Translational Medicine and Research. And lastly, the RBHS includes the University Behavioral Health Care.

Below is my interview with the Inaugural Henry Rutgers Professor of Global Health and Director of the Rutgers Global Health Institute Richard G. Marlink, M.D., which occurred in April, 2017.
You were recently appointed as the inaugural Henry Rutgers Professor of Global Health and Director of the new Rutgers Global Health Institute at Rutgers Biomedical and Health Sciences (RBHS). What are the goals of the new Institute?
Dr. Marlink: The overarching goal of the Rutgers Global Health Institute is to improve the health and wellness of individuals and populations in need both here and around the world, to create a healthier world through innovation, engineering, and technology, and to educate involved citizens and effective leaders in global health. We will do that by building on the aspiration of our originating organization — RBHS, which is to be recognized as one of the best academic health centers in the U.S., known for its education, research, clinical care, and commitment to improving access to health care and reducing health care disparities.
As the newly formed Rutgers Global Health Institute, we are embarking on an ambitious agenda to take advantage of the changing health care environment. Working across schools and disciplines at Rutgers University, we plan to have a significant impact within at least four signature programs identified by RBHS, which are cancer, environmental and occupational health, infection and inflammation, and public health. We also will include all other parts of Rutgers, as desired, beyond RBHS.
My background as a global health researcher, physician, and leader of grassroots health care delivery will help develop programs to undertake global health initiatives that assist populations locally and around the world. I believe that involved citizens, including students, can greatly impact major societal issues.
A key role in the strategic growth of Rutgers Biomedical and Health Sciences – an umbrella organization for eight schools, four centers and institutes and a behavioral health network — is to broaden the Rutgers University’s presence in the public health community globally to improve health and wellness. How will the new Rutgers Global Health Institute be part of this growth?
Dr. Marlink: Our RBHS Chancellor Brian Strom [M.D., M.P.H.] believes that we are positioned to become one of the finest research universities in the country, working cross-functionally with our three campuses in Newark, Camden and New Brunswick. In developing the strategic plan, Dr. Strom notes that we become much stronger and more capable and productive by leveraging our strengths to collaborate and working together across disciplines to best serve the needs of our community locally and globally.
Specifically, we are formulating plans to focus on these areas: old and new infectious disease epidemics; the expanding burden of noncommunicable diseases in poor populations; the social and environmental threats to health, poverty and humanitarian crises; and inadequate local and developing country health systems. We will support the development of global health research programs university-wide, the recruitment of faculty with interests in global health, and the creation of a web-based global health resource center for faculty and students with interests in these areas.
We are still a very young part of RBHS, and of Rutgers overall, so our plans are a work in progress. As tangible examples of our commitment to improving health and wellness globally, we plan to enhance global public health by establishing links between global public health and environmental and occupational health faculty in studies related to air pollution, climate change, and pesticide health.
Another example the Institute has in the works is expanding links with the School of Engineering. In fact, we are creating a senior-level joint faculty position with the School of Engineering and Rutgers-New Brunswick. Still other plans involve forging collaborative relationships between the Rutgers Cancer Program, under the auspices of Rutgers Cancer Institute of New Jersey, which is New Jersey’s only National Cancer Institute (NCI)-designated comprehensive cancer center, and other organizations and partners around the world, especially in poor and less-developed countries.
How is the Rutgers Global Health Institute strategically prepared for changing the health care paradigm?
Dr. Marlink: We intend to be an international global health leader in the health sciences, in public health, and in other related, but non-biomedical professions. This means that we will incorporate our learnings from laboratory sciences and the clinical, behavioral, and public health sciences, as well as from engineering, business, economics, law, and social sciences. This broad approach is critical in this health care environment as accountability for patient care is shifting to large groups of providers. Health care will be more value-driven and our health care teams must work collaboratively to be innovative. Our focus on health care is now also population-based, rather than only individual-based, and we are moving from large regional centers toward community centers, even in small and remote areas of the world. We are encouraged by rapid changes in technology that will provide new opportunities for shared knowledge, patient care and research.
Additionally, we are exploring ways to identify and recruit key faculty who will increase our breadth and depth of key disease areas as well as provide guidance on how to pursue science grants from the National Institute of Health (NIH)-funded program project grants and specialized research programs.
Currently, Rutgers University receives NIH funding for research in public health, population health, health promotion, wellness, health behavior, preventive medicine, and global health.
As a researcher, scholar and leader of grassroots health care delivery, how have your past positions prepared you for this new challenge? Your last position was the Bruce A. Beal, Robert L. Beal, and Alexander S. Beal Professor of the Practice of Public Health at Harvard University’s T.H. Chan School of Public Health and Executive Director of the Harvard AIDS Initiative.
Dr. Marlink: I have been a global health practitioner, researcher, and executive leader for almost three decades. I am trained in medical oncology and HIV medicine and have conducted clinical, epidemiological and implementation research in Africa since 1985. I was first introduced to global health when finishing my Hematology/Oncology fellowship at what is now the Beth Israel Deaconess Medical Center in the mid-1980’s in Boston.
During my Hematology/Oncology fellowship and after the co-organizing the first, hospital-based AIDS care clinic in the New England region, I was trying to learn the ropes in virology and molecular biology in the laboratory group of Max Essex at Harvard University. During that time in the mid-1980s, our laboratory group along with Senegalese and French collaborators discovered the first evidence for the existence of a new human retrovirus, HIV-2, a distinct second type of human AIDS virus, with its apparent origins in West Africa.
As a clinician, I was able to assist in Senegal, helping set up clinical care and create a research cohort in Dakar for hundreds of women sex workers infected with this new human retrovirus and care for them and their families. I discovered that a little can go a long way in poor settings, such as in Senegal. I became hooked on helping create solutions to help people in poor settings in Africa and elsewhere. Long-term partnerships and friendships have subsequently been made in many developing countries. Throughout my career, I have built successful partnerships with many governments, companies, and non-profit organizations, and those relationships have been the foundation to build successful public health partnerships in poor regions of the world.
In the 1990s, I helped create the Botswana-Harvard Partnership for HIV Research and Education (BHP). Through this partnership, the Government of Botswana and BHP have worked together to combat the AIDS epidemic in Botswana. Under my direction, and in partnership with the Botswana Ministry of Health, BHP launched the KITSO AIDS Training Program in 1999. Kitso is the Setswana word for ‘knowledge.”
KITSO is the national training program for physicians, nurses, and pharmacists, which has trained more than 14,000 health professionals in HIV/AIDS care and antiretroviral treatment. KITSO training modules address issues, such as antiretroviral therapy, HIV/AIDS-related disease management, gender-specific HIV issues, task-sharing, supportive and palliative care, and various psychosocial and counseling themes.
In addition, I was the Botswana County Director for Harvard Chan School’s 3-country President’s Emergency Plan AIDS Relief (PEPFAR) grant, The Botswana PEPFAR effort includes a Clinical and Laboratory Master Training Program and the creation of the Botswana Ministry of Health’s Monitoring and Evaluation Unit. Concurrently, I was the Principal Investigator of Project HEART in five African countries with the Elizabeth Glaser Pediatric AIDS Foundation.
Also in Botswana, in 2000, I was a co-founder of a distinct partnership involving a large commitment to the Government of Botswana from the Bill and Melinda Gates and Merck Foundations. This commitment continues as an independent non-governmental organization (NGO) to provide support for various AIDS prevention and care efforts in Botswana and the region.
All these global health experiences, it seems, have led me to my new role at the Rutgers Global Health Institute.
What is your advice for ways that the business community or university students can positively impact major societal issues?
Dr. Marlink: My advice is to be optimistic and follow that desire to want to make a difference. Margaret Mead, the American cultural anthropologist, said years ago, “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has.” I believe that to be our guiding principle as we embark on this new initiative.
I also believe that students should become specialized in specific areas prior to going fully into “global health,” as they develop in their careers, since they will then add more value later. For example, students should be grounded in the theory of global health in their undergraduate studies and then develop a specialization, such as becoming a statistician, economist, or medical doctor, to make a longer and greater impact in improving global health. As for the business community, we are looking for committed individuals who are specialized in specific areas to bring their knowledge to our organization, as partners in the fight against disease, improving the environment, or helping with humanitarian issues. We are committed to improving health and wellness, increasing access to the best health care, and reducing health disparities.
What is it about your current role that you enjoy the most?
Dr. Marlink: I enjoy building research, learning, and clinical programs, as I have in the HIV arena since the early 1980s. At that time, there were limited resources and funding, but a willingness among universities, non-governmental organizations, hospitals and the pharmaceutical industry to make a difference. Today in my new role, I’d like all of us to have an impact on health and wellness for those in need – to build programs from the ground up while partnering with organizations with the same goal in mind. I know it can be done.
Over my career, when I have a patient here or in a developed country who has been diagnosed with cancer, but is cured or in remission, that puts a huge smile on my face and in my heart. It also impacts you for the rest of your life. Or when I see an infant born without HIV because of the local country programs that are put in place, that also makes me feel so fulfilled, so happy.
I have worked with many talented individuals who have become great friends and partners over my career who have helped create a positive life for under-served populations around the world. We need to remember that progress happens with one person at a time or one program at a time. That’s how you truly improve health around the world.

Director of the Rutgers Global Health Institute
Rutgers Biomedical and Health Sciences
Richard G. Marlink, M.D., a Harvard University professor recognized internationally for research and leadership in the fight against AIDS, was recently appointed as the inaugural Henry Rutgers Professor of Global Health and Director of a new Rutgers Global Health Institute at Rutgers Biomedical and Health Sciences (RBHS). His role is to develop the strategic growth of RBHS by broadening the Rutgers University’s presence in the public health community to improve health and wellness.
Previously, Dr. Marlink was the Bruce A. Beal, Robert L. Beal, and Alexander S. Beal Professor of the Practice of Public Health at Harvard’s T.H. Chan School of Public Health and Executive Director of the Harvard AIDS Initiative.
At the start of the AIDS epidemic, Dr. Marlink was instrumental in setting up the first, hospital-based HIV/AIDS clinic in Boston, Massachusetts, and studied the impact of the HIV virus in west and central Africa. After helping to start the Botswana-Harvard Partnership in 1996, he founded the Kitso AIDS Training Program, which would become Botswana’s national AIDS training program. Kitso means knowledge in the local Setswana language.
Dr. Marlink was the principal investigator for the Tshepo Study, the first large-scale antiretroviral treatment study in Botswana, in addition to conducting other clinical and epidemiological studies in the region. Also in Botswana, he was the country director for Harvard’s contribution to the joint Botswana and United States governments’ HIV/AIDS and TB training, monitoring and evaluation PEPFAR effort.
In the mid-1980s in Senegal, Dr. Marlink was part of the team of Senegalese, French and American researchers who discovered and then studied the second type of human AIDS virus, HIV-2. Since then, he has been involved in multiple HIV/AIDS care, treatment and prevention programs in many African countries, including in Botswana, Côte d’Ivoire (Ivory Coast), Democratic Republic of the Congo, Kenya, Lesotho, Malawi, Mozambique, Rwanda, Senegal, South Africa, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe. He has also organized initiatives to enhance HIV/AIDS care in Brazil, Puerto Rico and Thailand.
Dr. Marlink has served as the scientific director, the vice president for implementation and the senior adviser for medical and scientific affairs at the Elizabeth Glaser Pediatric AIDS Foundation, where he was principal investigator of Project HEART, a five-country CDC/PEPFAR effort in Africa. That project began in 2004 and by 2011 had placed more than 1 million people living with HIV into care clinics. More than 565,000 of these people were placed on life-saving antiretroviral treatment.
Since 2000, Dr. Marlink has been the founding member of the board of directors of the African Comprehensive HIV/AIDS Partnerships, a public-partnership among the government of Botswana and the Bill and Melinda Gates and Merck Foundations to provide ongoing support for numerous HIV/AIDS prevention, care and treatment efforts in that country.
He has authored or co-authored more than 130 scientific articles; written a textbook, Global AIDS Crisis: A Reference Handbook; and co-edited the book, AIDS in Africa, 2nd Edition. Additionally, he served as chief editor for two special supplements to the journal AIDS and as executive editor of the seminal 320-author, three-volume textbook, From the Ground Up: A Guide to Building Comprehensive HIV/AIDS Care Programs in Resource Limited Settings.

Today’s fundamental challenge in Prostate cancer screening
Author and Curator: Dror Nir, PhD
Article 8.2.Todays fundamental challenge in Prostate cancer screening
The management of men with prostate cancer is becoming one of the most challenging public health issues in the Western world. It is characterized by: over-diagnosis; over-treatment; low treatment efficacy; treatment related toxicity; escalating cost; and unsustainability [Bangma et al, 2007; Esserman et al, 2009]. How come? Well, everyone accepts that most prostate cancers are clinically insignificant. It is well known that all men above 65 harbor some sort of prostate cancer. Due to the current aggressive PSA-based screening, one in six men will be diagnosed with prostate cancer. Yet, the lifetime risk of dying of prostate cancer is only 3%. The problem is that, once diagnosed with prostate cancer, there is no accurate tool to identify those men that will die of the disease (in my previous post I mentioned 1:37). Currently, screening practices for prostate cancer are relying on the very unspecific prostate-specific-antigen (PSA) bio-marker test to determine which men are at higher risk of harboring prostate cancer and therefore need a biopsy. The existing diagnostic test is a transrectal ultrasound (TRUS) guided prostate biopsy aimed at extracting representative tissue from areas where cancer usually resides. This procedure suffers from several obvious faults:
1. Since the imaging tool used (B-mode ultrasound) is poor at detecting malignancies in the prostate, the probability of hitting a clinically significant cancer or missing a clinically insignificant cancer is subject to random error.
2. TRUS biopsy is also subjected to systematic error as it misses large parts of the prostate which might harbor cancer (e.g. apex and anterior zones). 3. TRUS guided biopsies are often unrepresentative of the true burden of cancer as either the volume or grade of cancer can be underestimated.
In the last ten years I was leading the development of an innovative ultrasound-based technology, HistoScanningTM, aimed at improving the aforementioned faults;
In my future posts I will go into more detail on how these imaging modalities fit into routine workflow, how much they stay within budget constraints and what level of promise they bear for promoting personalized medicine. Stay tuned… Footnote: According to the final report by an advisory panel to the USA government: Doctors should no longer offer the PSA prostate cancer screening test to healthy men because they’re more likely to be harmed by the blood draw, and the chain of medical interventions that often follows than be helped; (http://www.usatoday.com/news/health/story/2012-05-21/prostate-cancer-screening-test-harmful/55118036/1)But then; what should be offered instead?

Prostate Cancers Plunged After USPSTF Guidance, Will It Happen Again?
The plan for this council was announced at the UN Conference on Sustainable Development, or Rio+20 — the UN Environmental, Scientific and Cultural Organization will be taking the lead in setting the board up.
“The board will bring together eminent specialists from the natural sciences, the social and human sciences, and engineering, and representing diverse backgrounds and regions,” SciDevNet adds
This study was reported today in the Optical Society’s (OSA) open-access journal Optics Express (Optics Express, Vol. 20, Issue 11, pp. 11582-11597 (2012)), and provide proof-of-concept support that the technology can distinguish malignant tissue by providing high-contrast images of tumors.
In breast cancer screening, x-ray mammography and ultrasonography are primarily used to understand any morphological changes of breast tissue. However, these conventional techniques have their own drawbacks because of for example ionizing radiation that could cause leukemia after prolonged/ repeated exposure where as ultrasonography is strongly operator dependent.
Tumor vascularization is a crucial feature in breast imaging. One commonly used method that focuses on tumor vascularization is Dynamic Contrast Enhanced MRI (DCE-MRI). The high sensitivity of this technique for detecting breast cancer proves that vascularity can indeed provide additional information about the nature of tissue. However, DCE-MRI suffers from a limited specificity, requires the injection of contrast agents and is relatively expensive.
Far-red and near-infrared (NIR): It is gaining attention in (non-invasively) visualizing cancer and its associated vasculature due to its ability to provide functional and molecular information without the use of ionizing radiation. In recent studies, it has been shown that optical imaging in the form of diffuse optical tomography (DOT) can indeed visualize breast malignancies, primarily because of the high absorption of hemoglobin in the NIR regime. However, DOT suffers from low spatial resolution.
Several groups have studied the feasibility of photoacoustic image (PAI) in breast imaging due to their superior resolution capabilities to that of pure optical techniques. Photoacoustic imaging exploits the high NIR light absorption contrast between benign and malignant tissue, but provides superior resolution arising from ultrasound detection.
Scientists from Center for Breast Care, Medisch Spectrum Twente hospital, University of Twente and University of Amsterdam have developed the Twente Photoacoustic Mammoscope (PAM), to image the breast in transmission mode. The authors say that, in a first pilot study with this system in 2007, it was possible to get technically acceptable measurements on five patients with radiographically proven breast malignancies. Of those, four cases revealed a high photoacoustic contrast with respect to the background associated with tumor related vasculature. Now the authors have recently started an extended clinical study using PAM, as a continuation of the study performed in 2007.
In this new study, they have investigated the clinical feasibility of photoacoustic mammography in a larger group of patients with different types of breast lesions to obtain more information about the clinical feasibility and limitations of photoacoustic mammography and the results were compared with conventional imaging and histopathology.
Ten technically acceptable measurements on patients with malignancies (BI-RADS 5) and two measurements on patients with cysts (BI-RADS 2) were performed. In the reconstructed volumes of all ten malignant lesions, a confined region with high contrast with respect to the background was seen. In all malignant cases, the PA contrast of the abnormality was higher than the contrast on x-ray mammography. The PA contrast appeared to be independent of the mammographically estimated breast density and was absent in the case of cysts.
Authors say that technological improvements to the instrument and further studies on less suspicious lesions are planned to further investigate the potential of PAM. The authors from University of Twente hope that these early results will one day lead to the development of a safe, comfortable, and accurate alternative or adjunct to conventional techniques for detecting breast tumors.
Twente Photoacoustic Mammoscope (PAM):
This techniques combines the light-based system’s to distinguish between benign and malignant tissue with ultrasound to achieve superior targeting ability. The device is built into a hospital bed, where the patient lies prone and positions her breast for imaging. Laser light at a wavelength of 1,064 nm scans the breast. Because there is increased absorption of the light in malignant tissue the temperature slightly increases. With the rise in temperature, thermal expansion creates a pressure wave, which is detected by an ultrasound detector placed on one side of the breast. The resulting photoacoustic signals are then processed by the PAM system and reconstructed into images. These images reveal abnormal areas of high intensity (tumor tissue) as compared to areas of low intensity (benign tissue). This is one of the first times that the technique has been tested on breast cancer patients.
Note: Breast cancer is one of the most common forms of cancer among females and each year more than 450,000 women are diagnosed worldwide with the disease.
Re: Radiation Scatter Survey of Radial Assist RAD BOARD by Alliance Medical Physics LLC
Enclosed please find the results of the radiation scatter survey conducted on the RAD BOARD on April 20, 2012. The RAD BOARD is an arm board utilized in cardiac catheterization and interventional labs for radial access. It has the added feature of being partially lined with a 15″ by 9″ layer of Xenolite TB for additional radiation scatter protection. Xenolite TB, which is a lead-free, super-lightweight 2-element composite equivalent to 0.35mm Pb protection, is embedded in the board under the company logo label. The survey was performed to quantify the ability of the RAD BOARD to reduce radiation scatter to the physician performing the vascular procedure.
RADIATION SCATTER SURVEY RESULTS
The resultsof the survey indicate that when utilizing the RAD BOARD, radiation scatter exposure levels were reduced by 33% – 40% at waist height, and 21% – 30% at neck height (See Figures 1 & 2).

Cancer is a broad group of various diseases involving unregulated cell growth. It is medically known as a malignant neoplasm. In cancer, cells divide and grow uncontrollably and invade nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream, it is called metastasis. However, not all tumors are cancerous. Some tumors do not grow uncontrollably, do not invade neighboring tissues, and do not spread throughout the body which are called Benign tumors.
There are more than 100 types of Cancers. Follow the link to know more:
Cancer is usually treated with chemotherapy, radiation therapy and surgery.
Survival
Survival depends greatly by the type and location of the cancer and the extent of disease at the start of treatment. The risk of developing cancer generally increases with age.
Young People with Cancer, visit the following link for details:
Initially there will be no signs and symptoms but only appearing as the mass that continues to grow or ulcerates. The findings that result depends on the type and location of the cancer. For example,
Mass effects from Lung Cancer – can cause blockage of the bronchus resulting in cough (coughing up blood if there is ulceration) or pneumonia.
Oesophageal Cancer – can cause narrowing of the esophagus making it difficult or painful to swallow.
Colorectal Cancer – may lead to changes in bowel habits and bleeding leading to anemia.
General symptoms may include:
Unintentional weight loss,
Fever,
Being excessively tired,
Changes to the skin,
Hodgkin disease,
Leukemias, and
Persistent fever due to Cancers of the liver or kidney.
Symptoms of metastasis include:
Enlarged lynph nodes which can be felt or sometimes seen under the skin and are typically hard),
Enlarged liver or spleen which can be felt in the abdomen,
Pain or fracture of affected bones, and
Neurological symptoms.
It is nearly impossible to prove what caused a cancer in any individual, because most cancers have multiple possible causes. For example, lung cancer could be due to tobacco habbit or could be a result of air pollution or radiation.
