We conducted a cluster-randomized trial to measure the effect of community-level mask distribution and promotion on symptomatic SARS-CoV-2 infections in rural Bangladesh from November 2020 to April 2021 (N = 600 villages, N = 342,183 adults). We cross-randomized mask type (cloth vs. surgical) and promotion strategies at the village and household level. Proper mask-wearing increased from 13.3% in the control group to 42.3% in the intervention arm (adjusted percentage point difference = 0.29 [0.26, 0.31]). The intervention reduced symptomatic seroprevalence (adjusted prevalence ratio (aPR) = 0.91 [0.82, 1.00]), especially among adults 60+ years in villages where surgical masks were distributed (aPR = 0.65 [0.45, 0.85]). Mask distribution and promotion was a scalable and effective method to reduce symptomatic SARS-CoV-2 infections.

The rapid growth of electricity demand in developing nations, the availability of complementary generation resources, and the emergence of digital technologies have created increased opportunities for the international electricity trade. This paper proposes a framework for cross- border electricity trade (CBET) in the Bangladesh–Bhutan–India–Nepal (BBIN) Region that recognises the governance challenges associated with establishing an international electricity market. We explore the lessons for the BBIN Region derived from different types of CBET models. Specifically, existing markets in Northwest Europe, Latin America, and the United States provide insights into the development of our proposed cost-based CBET framework. We provide recommendations based on our proposed CBET framework to improve efficiency and increase the extent of electricity trade in the BBIN Region.

Most of the stillbirths that occur around the world are among women who live in low- and middle-income countries. Some 2.5 million women suffer the heartbreaking loss each year.

Yet determining the causes and prevention of stillbirths has largely been ignored as a global health priority — the incidence not even included in the WHO Millennium Development Goals.

Stanford Health Policy’s Rosenkranz Prize Winner, Ashley Styczynski, MD, MPH, discovered the alarmingly high level of stillbirths while working in Bangladesh as a 2019-2020 Fogarty Fellow, studying antimicrobial resistance in newborns in the hospitals there.

The $100,000 Rosenkranz Prize is awarded to a Stanford researcher who is doing innovative work to improve health in the developing world.

“I was surprised to learn that the rates of stillbirths were comparable to sub-Saharan Africa and that in many cases they had no idea of the cause,” Styczynski said in a Skype call from Dhaka, where she has been living for eight months while conducting her antimicrobial resistance research.

specimen collection1 copy Rosenkranz Prize Winner Ashley Styczynski takes specimen samples with women in Dhaka, Bangladesh, for her research on antimicrobial resistance in newborns. This research led to her prize-winning proposal to investigate the alarmingly high rate of stillbirths in the South Asian nation.

The South Asian nation is among the top 10 countries with the highest number of stillbirths, with an average of 25.4 stillbirths per 1,000 births. Studies have implicated maternal infections as the cause; one ongoing study in Bangladesh has recovered bacteria from blood samples in stillborn babies in whom no prior maternal infection was suspected.

Styczynski believes intrauterine infections may be an underrecognized factor contributing to the excess stillbirths in Bangladesh. She intends to perform metagenomic sequencing on placental tissues of stillborn babies, a process that will allow her to examine the genes in the organisms of those tissues and evaluate the bacterial diversity.

“The alternative hypothesis would be that stillbirths are caused by non-infectious etiologies, which I will be assessing through interviews,” Styczynski wrote in her Rosenkranz application.

Those interviews will be with mothers to evaluate for frequency of infectious symptoms during pregnancy, including fever, rash, cough, dysuria and diarrhea, as well as possible toxin exposures. She will compare the findings with the metagenomic sequencing results to determine how frequently potential pathogens may be presenting as subclinical infections.

My goal is to reduce excess stillbirths by identifying risk factors and pathogens that may be contributing to stillbirths and, ultimately, to design prevention strategies.

Rosenkranz Prize Winner

“By applying advanced technologies and software platforms, this research will not only enhance our understanding of causes of stillbirths in Bangladesh, but it may also provide insights into causes of early neonatal deaths," Styczynski said.

Bangladesh, one of the poorest and most densely populated nations in the world, offers a rich variety of emerging and known diseases that go undetected.

“The panoply of infections that could contribute to stillbirths is really unknown,” Styczynski said. “That’s why metagenomics is a great tool here. It just hasn’t been accessible here because of the expense. Now this tool will begin to unpack what’s causing these stillbirths.”

The Rosenkranz Prize was started and endowed by the family of the late Dr. George Rosenkranz, who devoted his career to improving health-care access across the world and helped synthesize the active ingredient for the first oral birth control pill.

“No one is more deserving of the Rosenkranz Prize than Dr. Ashley Styczynski”, said Dr. Ricardo Rosenkranz. “Because of her tenacity, originality and focus, Dr. Styczynski exemplifies the ideal Rosenkranz Prize recipient. She has chosen an often overlooked adverse outcome that may prove to be mitigated by her findings. As a neonatologist interested in health disparities, I fully realize the potential relevance and urgency of her work and am excited to see it come to fruition. As the son of George Rosenkranz, for whom this prize is lovingly named, I know that my father would appreciate Dr. Styczynski’s pioneering spirit as well as her desire to affect global positive change by improving medical outcomes in vulnerable communities. We can’t wait to celebrate her work back at Stanford in the near future."

Sheltering in Place

Styczynski spoke from her flat in Dhaka, where she has been confined for three weeks as the world’s third-most populated city prepares for the onslaught of the coronavirus. The country is on lockdown; no international flights in or out.

As of Thursday, there were 1,572 cases in Bangladesh and 60 deaths, according to the widely used Johns Hopkins Coronavirus Map.

But Styczynski believes that’s about 1% of the actual disease activity in the country because testing was so slow to start. She said there is great stigma in the country over testing — red flags are put on the homes of those who have been diagnosed with COVID-19 — because it breaks up the unity of families and the surrounding community. Health-care workers are being kicked out of apartments by frightened landlords and people are afraid to use the health-care system for fear of infection.

“So, the hospitals are quite empty — more so than they’ve ever been,” she said.

Styczynski likened it to waiting for the tsunami that you know is coming.

“That’s why I wanted to jump in to stave off the morbidity and mortality that will be inundating one of the most populated countries in the world,” she said. Some 165 million people are packed into 50,250 square miles — a land mass about the same size as New York State, which has some 19.5 million people.

The Centers for Disease Control and Prevention (CDC) has a small team of four people working in Bangladesh. Having spent two years as an Epidemic Intelligence Service Officer at the CDC, Styczynski has now joined its Bangladesh team and is also working with the infection prevention and control team of the International Centre for Diarrhoeal Disease Research, Bangladesh.

“Many people here in Dhaka live in high-density apartments with six to 12 people living in the same room,” she said. “How do you isolate when you have a one-room home?”

Ninety percent of the population are daily wage earners, Styczynski noted, who say they’d rather take their chances with coronavirus than die of starvation.

They take those chances at great risk. There is one ventilator for every 100,000 people in Bangladesh and the district hospitals have maybe one to two days of oxygen supply, Styczynski said.

They started out training military hospitals on medical triage, quarantine and isolation, and infection prevention strategies.

“We’ve also been going to some district hospitals to assess some of the challenges they are facing and to identify some of the gaps in preparedness so that we can communicate back to the Ministry of Health how they can better support these district hospitals,” she said.

Her pandemic travels to the district hospitals and preparedness work has allowed her to gather contextual data for her colleagues back at Stanford who are working to address the lack of personal protective equipment (PPE) in low-resourced countries.

“We hope we can generate some evidence very quickly so that we can share some of this information to better protect health-care workers in other low-resource countries,” she said.

Despite her research being temporarily sidelined, Styczynski is upbeat.

“This is what I signed up for as a Fogarty fellow, to help build local capacity,” she said. “But I am also an infectious disease specialist, and these are the types of situations we run towards rather than away from. We build our career for moments like these.”

Abstract: Clay fired bricks are a primary building material used in the rapidly expanding construction sector across South Asia. These bricks are primarily manufactured by small enterprises using inefficient, highly polluting coal-fired kilns. The black carbon and the greenhouse gases emitted by brick kilns across South Asia is comparable to the global radiative forcing of the entire US passenger car fleet. The pollution generated by these brick kilns also affect human health. In Dhaka, Bangladesh brick kilns contribute 40% of the ambient particulate matter during winter and are estimated to result in 5000 adult deaths each year. In addition, the coercive collection of topsoil as part of clay mining undermines agricultural productivity in settings of high poverty and malnutrition.

This talk will discuss why bricks are manufactured in Bangladesh using an approach that is so damaging to the environment and to public health. It will explore combined technical, financial and political strategies to transform the sector.

Protecting freedom of expression is essential to vibrant democracies and to meet the needs of people now and into the future, Indian historian Ramachandra Guha said at a Stanford event seeking to draw people together for policy-relevant discussions about India’s growth following 25 years of reforms.

Guha’s remarks were part of a colloquium titled “Eight Threats to Freedom of Expression in India,” and one in a series, co-hosted by the Shorenstein Asia-Pacific Research Center (APARC) and Center for South Asia.

The colloquia, which continue this spring, are motivated by an opportunity to garner reflections and expertise from Kathleen Stephens, the William J. Perry Fellow in the Freeman Spogli Institute, who served as chargé d'affaires at the U.S. Embassy New Delhi in 2014.

“As I was preparing to go to India, I read Ram’s extraordinary book India after Gandhi, which provided much-needed historical, cultural and political context,” Stephens said. “When I visited Bangalore, we met and instantly clicked as we talked about U.S.-India relations. It’s a pleasure to welcome him back to Stanford.”

Guha, a renowned author and scholar, has written numerous critically acclaimed books about India’s history and culture as well as social ecology, and is a frequent commentary contributor to publications such as The Telegraph and Hindustan Times. In 2000, Guha was a visiting professor at Stanford, where he taught courses on the politics and culture of South Asia and cross-cultural perspectives on the global environmental debate.

India is often referred to as the world’s largest democracy for its population size of 1.3 billion and system of governance since partition and independence in 1947. Guha said that, while India is “solidly and certifiably democratic,” there are serious flaws, including growing threats to freedom of expression of Indian artists, filmmakers and writers.

Indian society, Guha said, has become too sensitive to criticism, wherein “somebody will take objection” to any message. This kind of environment has encouraged newspaper editors to self-censor, for example, and led public figures to, at times, neglect to protect artists, filmmakers and writers.

In total, Guha detailed eight threats to freedom of expression in contemporary India: 1) archaic colonial laws affecting the first amendment, 2) imperfections in the judicial system, 3) rising importance of identity politics, 4) complicity of the police force, 5) pusillanimity of politicians, 6) dependence of media on government-sponsored advertisements, 7) dependence of media on commercially-sponsored advertisements and 8) ideologically–driven writers.

Would an absence of those threats imply freedom of expression? Responding to the question from the audience, Guha lamented that the answer wasn’t simple. His task was to offer a diagnosis of the challenges, he said, and not provide instruction on how to solve them, but in general, focused efforts bear change.

“Building democracies is about quiet persistent work,” Guha said of next steps in the process to extinguish threats to freedom of expression. “I think quiet persistent work in repairing our institutions, modernizing our laws and improving civil society institutions can still mitigate some of the threats.”

Guha expressed optimism about India’s civil society, noting an expansion in the supply of non-governmental organizations working on social issues and private philanthropists funding projects in that sector. But he tempered: “we could do more.”

Stephens ended the event by thanking Guha for leading the discussion, and referenced America’s first president George Washington, who at the end of his term in office, called upon citizens to be “‘anxious, jealous guardians of our democracy.’”

“And, I see that today in Ram and in the many people here – very jealous, anxious and passionate guardians of our democracy – who we can learn a lot from,” she said.

The number of people served by networked systems that supply intermittent and contaminated drinking water is increasing. In these settings, centralized water treatment is ineffective, while household-level water treatment technologies have not been brought to scale. This study compares a novel low-cost technology designed to passively (automatically) dispense chlorine at shared handpumps with a household-level intervention providing water disinfection tablets (Aquatab), safe water storage containers, and behavior promotion. Twenty compounds were enrolled in Dhaka, Bangladesh, and randomly assigned to one of three groups: passive chlorinator, Aquatabs, or control. Over a 10-month intervention period, the mean percentage of households whose stored drinking water had detectable total chlorine was 75% in compounds with access to the passive chlorinator, 72% in compounds receiving Aquatabs, and 6% in control compounds. Both interventions also significantly improved microbial water quality. Aquatabs usage fell by 50% after behavioral promotion visits concluded, suggesting intensive promotion is necessary for sustained uptake. The study findings suggest high potential for an automated decentralized water treatment system to increase consistent access to clean water in low-income urban communities.

Background

During a fatal Nipah virus (NiV) outbreak in Bangladesh, residents rejected biomedical explanations of NiV transmission and treatment and lost trust in the public healthcare system. Field anthropologists developed and communicated a prevention strategy to bridge the gap between the biomedical and local explanation of the outbreak.

Methods

We explored residents’ beliefs and perceptions about the illness and care-seeking practices and explained prevention messages following an interactive strategy with the aid of photos showed the types of contact that can lead to NiV transmission from bats to humans by drinking raw date palm sap and from person-to-person.

Results

The residents initially believed that the outbreak was caused by supernatural forces and continued drinking raw date palm sap despite messages from local health authorities to stop. Participants in community meetings stated that the initial messages did not explain that bats were the source of this virus. After our intervention, participants responded that they now understood how NiV could be transmitted and would abstain from raw sap consumption and maintain safer behaviours while caring for patients.

Conclusions

During outbreaks, one-way behaviour change communication without meaningful causal explanations is unlikely to be effective. Based on the cultural context, interactive communication strategies in lay language with supporting evidence can make biomedical prevention messages credible in affected communities, even among those who initially invoke supernatural causal explanations.

Abstract:

Brick kilns in Bangladesh use inefficient coal burning technology that generates substantial air pollution. We investigated the incentives of stakeholders in brick manufacturing in Bangladesh to help inform strategies to reduce this pollution. A team of Bangladeshi anthropologists conducted in-depth interviews with brick buyers, kiln owners, and Department of Environment employees. Brick buyers reported that bricks manufactured in traditional kilns worked well for most construction purposes and cost 40% less than bricks manufactured in more modern, less polluting, kilns. Brick kiln owners favored approaches with rapid high return on a modest investment. They preferred kilns that operate only during the dry season, allowing them to use cheaper low-lying flood plain land and inexpensive seasonal labor. The Department of Environment employees reported that many kilns violate environmental regulations but shortages of equipment and manpower combined with political connections of kiln owners undermine enforcement. The system of brick manufacturing in Bangladesh is an economic equilibrium with the manufacture of inexpensive bricks supplying the demand for construction materials but at high cost to the environment and health of the population. Low-cost changes to improve kiln efficiency and reduce emissions could help move toward a more socially desirable equilibrium.
