At the front lines of global health messaging: A conversation with WHO’s retired communications director

A virus never before seen in humans is killing people around the world. What do you say to a global audience desperate to learn more? Gabriella Stern faced this question head-on. For more than six years, she served as director of communications at the World Health Organization, including throughout the COVID-19 pandemic. In this fireside chat, Stern will share stories from the front lines of global health communication—what it takes to craft and deliver clear, trusted messaging on issues ranging from infectious disease outbreaks to humanitarian crises to massive public health funding cuts—all while navigating a rapidly evolving communications landscape.

How our surroundings shape health: A conversation between environmental scientists

For more than 50 years, Jack Spengler has advanced our understanding of how environment shapes health through pioneering research on the importance of air quality, healthy buildings, and climate resilience. In conversation with longtime collaborator Linda Powers Tomasso, Spengler explores how the places we live, learn, and work shape human health. Together, they reflect on the evolution of environmental health over five decades and the importance of continued collaboration and mentorship in shaping a more sustainable future.

Screening for Major Diseases — Does it help?

The Cutter Lectures on Preventive Medicine – 10th Symposium
Part of the Cutter Lectures on Preventive Medicine series, The 10th Cutter Symposium “Screening for Major Diseases—Does It Help?” will feature three separate lectures from expert speakers on the topic of screening for colorectal cancer, prostate cancer, and infectious diseases followed by a moderated Q&A segment with all the speakers. This symposium is open to the public & is virtual only.
Schedule of talks:
| 1:00PM | Introducing the Cutter Symposium Albert Hofman, MD, PhD |
| 1:05PM | The Power of Colorectal Cancer Screening Hermann Brenner, MD. MPH Abstract: Over 30 years ago, in 1993, a groundbreaking analysis of the US National Polyp Study was published, which suggested that colonoscopic removal of colorectal polyps was associated with an 88% reduction of colorectal cancer incidence. Since then, numerous observational studies and randomized trials have confirmed effectiveness of colorectal cancer screening, even though most of them substantially underestimated screening effects for various reasons. Large heterogeneity in introduction of and adherence to screening programs across countries in the last three decades is mirrored in large heterogeneity of trends in colorectal cancer incidence and mortality. Modelling studies based on the accumulated evidence confirm that the vast majority of the approximately one million colorectal cancer deaths per year globally could be prevented by screening. |
| 1:35PM | Controversies and Innovations in Screening for Prostate Cancer Lorelei Mucci, ScD Abstract: More than 1.6 million men across the globe are diagnosed with prostate cancer annually, and it is the leading cause of cancer death in more than 50 countries. In randomized controlled trials, screening with prostate specific antigen (PSA) has been shown to reduce cancer mortality over two decades. However, PSA screening also has led to overdiagnosis of prostate cancers that have a low potential for metastasis and concomitant overtreatment of patients. What has ensued over the past two decades has been an active debate about the harms and benefits of screening, guidelines that are often in conflict with one another, and in the United States, a substantial reduction in prostate cancer screening that is now tied to an uptake in incidence of metastatic prostate cancer. This talk will provide an overview of the history of PSA screening, the evidence around risks and harms, the controversies, and recent innovations in approaches to accelerate a risk stratified approach to screening. |
| 2:05PM | Diagnostics, Screening, and Surveillance in Pandemics Marc Lipsitch, DPhil Abstract: This talk will describe challenges and opportunities for surveillance during large infectious disease events, with lessons from COVID-19 and earlier pandemics. Active testing of population-based random samples provide numerous advantages over passive case detection in many situations, while linked data on demographics, severity, and pathogen variant among other characteristics are far more valuable for decision making than the same data if unlinked. Better data can inform more efficient decisions about control measures that improve the ratio of disease control effectiveness to cost and disruption. |
| 2:35PM | General Discussion |
| 3:00PM | Closing by Albert Hofman |
Speakers will share their own perspectives; they do not speak for Harvard.

Why Stability Matters for Early Childhood Development
Join the Center on the Developing Child’s upcoming webinar to explore why stability plays a critical role in shaping young children’s health and development.
Drawing on insights from the new working paper, From Resources to Routines: The Importance of Stability in the Developmental Environment, the conversation will examine how stability—or the lack of it—across children’s developmental environments can affect their well-being in the moment and across the lifespan, and highlight strategies to promote stability for young children and their caregivers.
The conversation will be moderated by our Chief Science Officer, Lindsey Burghardt, MD, MPH, FAAP, and feature Nathaniel Harnett, PhD, Assistant Professor in Psychiatry at Harvard Medical School, and Natalie Slopen, ScD, Associate Professor of Social and Behavioral Sciences at Harvard T. H. Chan School of Public Health.

CHDS Seminar with Christopher Jackson

Join the Center for Health Decision Science for a seminar with Christopher Jackson from the University of Cambridge, UK, titled, “Making Semi-Markov Multistate Models for Intermittent Observations Easily Usable.” Multi-state models for changes in a state (e.g. of health or illness) often assume that the transition rate is constant with time spent in the state (the “Markov” assumption). In this seminar, Jackson proposes a new method and software package to relax this often-unrealistic assumption, using hidden states known as “phases.” This is motivated by applications such as modelling the duration of infections, modelling time in a detectable state in cancer screening, and modelling cognitive impairment in studies of ageing.
Christopher Jackson is a Senior Statistician at the MRC Biostatistics Unit, University of Cambridge. His research involves incorporating statistical methods in models to combine evidence to inform population health policy. His publications cover Bayesian evidence synthesis, survival analysis, multi-state modelling, longitudinal data, decision theory, and model comparison. He has also developed several popular R packages, and co-authored two textbooks, “The BUGS Book” and “Value of Information for Healthcare Decision-Making.”
