Low antibody levels associated with significantly increased rate of SARS-CoV-2 infection in a highly vaccinated population from the US National Basketball Association.

SARS-CoV-2 antibody levels may serve as a correlate for immunity and could inform optimal booster timing. The relationship between antibody levels and protection from infection was evaluated in vaccinated individuals from the US National Basketball Association who had antibody levels measured at a single time point from September 12, 2021, to December 31, 2021. Cox proportional hazards models were used to estimate the risk of infection within 90 days of serologic testing by antibody level (<250, 250-800, and >800 AU/mL1 ), adjusting for age, time since last vaccine dose, and history of SARS-CoV-2 infection. Individuals were censored on date of booster receipt. The analytic cohort comprised 2323 individuals and was 78.2% male, 68.1% aged ≤40 years, and 56.4% vaccinated (primary series) with the Pfizer-BioNTech mRNA vaccine. Among the 2248 (96.8%) individuals not yet boosted at antibody testing, 77% completed their primary vaccine series 4-6 months before testing and the median (interquartile range) antibody level was 293.5 (interquartile range: 121.0-740.5) AU/mL. Those with levels <250 AU/mL (adj hazard ratio [HR]: 2.4; 95% confidence interval [CI]: 1.5-3.7) and 250-800 AU/mL (adj HR: 1.5; 95% CI: 0.98-2.4) had greater infection risk compared to those with levels >800 AU/mL. Antibody levels could inform individual COVID-19 risk and booster scheduling.

The "Bubble": What Can Be Learned from the National Basketball Association (NBA)'s 2019-20 Season Restart in Orlando during the COVID-19 Pandemic.

BACKGROUND: The National Basketball Association (NBA) suspended operations in response to the COVID-19 pandemic in March 2020. To safely complete the 2019-20 season, the NBA created a closed campus in Orlando, Florida, known as the NBA "Bubble." More than 5000 individuals lived, worked, and played basketball at a time of high local prevalence of SARS-CoV-2. METHODS: Stringent protocols governed campus life to protect NBA and support personnel from contracting COVID-19. Participants quarantined before departure and upon arrival. Medical and social protocols required that participants remain on campus, test regularly, physically distance, mask, use hand hygiene, and more. Cleaning, disinfection, and air filtration was enhanced. Campus residents were screened daily and confirmed cases of COVID-19 were investigated. RESULTS: In the Bubble population, 148 043 COVID-19 reverse transcriptase PCR (RT-PCR) tests were performed across approximately 5000 individuals; Orlando had a 4% to 15% test positivity rate in this timeframe. There were 44 COVID-19 cases diagnosed either among persons during arrival quarantine or in non-team personnel while working on campus after testing but before receipt of a positive result. No cases of COVID-19 were identified among NBA players or NBA team staff living in the Bubble once cleared from quarantine. CONCLUSIONS: Drivers of success included the requirement for players and team staff to reside and remain on campus, well-trained compliance monitors, unified communication, layers of protection between teams and the outside, activation of high-quality laboratory diagnostics, and available mental health services. An emphasis on data management, evidence-based decision-making, and the willingness to evolve protocols were instrumental to successful operations. These lessons hold broad applicability for future pandemic preparedness efforts.

World Health Organization and knowledge translation in maternal, newborn, child and adolescent health and nutrition.

The World Health Organization (WHO) has a mandate to promote maternal and child health and welfare through support to governments in the form of technical assistance, standards, epidemiological and statistical services, promoting teaching and training of healthcare professionals and providing direct aid in emergencies. The Strategic and Technical Advisory Group of Experts (STAGE) for maternal, newborn, child and adolescent health and nutrition (MNCAHN) was established in 2020 to advise the Director-General of WHO on issues relating to MNCAHN. STAGE comprises individuals from multiple low-income and middle-income and high-income countries, has representatives from many professional disciplines and with diverse experience and interests.Progress in MNCAHN requires improvements in quality of services, equity of access and the evolution of services as technical guidance, community needs and epidemiology changes. Knowledge translation of WHO guidance and other guidelines is an important part of this. Countries need effective and responsive structures for adaptation and implementation of evidence-based interventions, strategies to improve guideline uptake, education and training and mechanisms to monitor quality and safety. This paper summarises STAGE's recommendations on how to improve knowledge translation in MNCAHN. They include support for national and regional technical advisory groups and subnational committees that coordinate maternal and child health; support for national plans for MNCAHN and their implementation and monitoring; the production of a small number of consolidated MNCAHN guidelines to promote integrated and holistic care; education and quality improvement strategies to support guidelines uptake; monitoring of gaps in knowledge translation and operational research in MNCAHN.

Reinfections were infrequent and varied in clinical presentation, viral dynamics, and immune response.

Drivers of the reduction in childhood diarrhea mortality 1980-2015 and interventions to eliminate preventable diarrhea deaths by 2030.

BACKGROUND: Childhood diarrhea deaths have declined more than 80% from 1980 to 2015, in spite of an increase in the number of children in low- and middle-income countries (LMIC). Possible drivers of this remarkable accomplishment can guide the further reduction of the half million annual child deaths from diarrhea that still occur. METHODS: We used the Lives Saved Tool, which models effects on mortality due to changes in coverage of preventive or therapeutic interventions or risk factors, for 50 LMIC to determine the proximal drivers of the diarrhea mortality reduction. RESULTS: Diarrhea treatment (oral rehydration solution [ORS], zinc, antibiotics for dysentery and management of persistent diarrhea) and use of rotavirus vaccine accounted for 49.7% of the diarrhea mortality reduction from 1980 to 2015. Improvements in nutrition (stunting, wasting, breastfeeding practices, vitamin A) accounted for 38.8% and improvements in water, sanitation and handwashing for 11.5%. The contribution of ORS was greater from 1980 to 2000 (58.0% of the reduction) than from 2000 to 2015 (30.7%); coverage of ORS increased from zero in 1980 to 29.5% in 2000 and more slowly to 44.1% by 2015. To eliminate the remaining childhood diarrhea deaths globally, all these interventions will be needed. Scaling up diarrhea treatment and rotavirus vaccine, to 90% coverage could reduce global child diarrhea mortality by 74.1% from 2015 levels by 2030. Adding improved nutrition could increase that to 89.1%. Finally, adding increased use of improved water sources, sanitation and handwashing could result in a 92.8% reduction from the 2015 level. CONCLUSIONS: Employing the interventions that have resulted in such a large reduction in diarrhea mortality in the last 35 years can virtually eliminate remaining childhood diarrhea deaths by 2030.

Evolution of the World Health Organization's programmatic actions to control diarrheal diseases.

The Program for the Control of Diarrheal Diseases (CDD) of the World Health Organization (WHO) was created in 1978, the year the Health for All Strategy was launched at the Alma Ata International Conference on Primary Health Care. CDD quickly became one of the pillars of this strategy, with its primary goal of reducing diarrhea-associated mortality among infants and young children in developing countries. WHO expanded the previous cholera-focused unit into one that addressed all diarrheal diseases, and uniquely combined support to research and to national CDD Programs. We describe the history of the Program, summarize the results of the research it supported, and illustrate the outcome of the Program's control efforts at country and global levels. We then relate the subsequent evolution of the Program to an approach that was more technically broad and programmatically narrow and describe how this affected diarrheal diseases-related activities globally and in countries.

Factors associated with the decline in under-five diarrhea mortality in India: a LiST analysis.

BACKGROUND: India has achieved 86% reduction in the number of under-five diarrheal deaths from 1980 to 2015. Nonetheless diarrhea is still among the leading causes of under-five deaths. The aim of this analysis was to study the contribution of factors that led to decline in diarrheal deaths in the country and the effect of scaling up of intervention packages to address the remaining diarrheal deaths. METHODS: We assessed the attribution of different factors and intervention packages such as direct diarrhea case management interventions, nutritional factors and WASH interventions which contributed to diarrhea specific under-five mortality reduction (DSMR) during 1980 to 2015 using the Lives Saved Tool (LiST). The potential impact of scaling up different packages of interventions to achieve universal coverage levels by year 2030 on reducing the number of remaining diarrheal deaths were estimated. RESULTS: The major factors associated with DSMR reduction in under-fives during 1980 to 2015, were increase in ORS use, reduction in stunting prevalence, improved sanitation, changes in age appropriate breastfeeding practices, increase in the vitamin-A supplementation and persistent diarrhea treatment. ORS use and reduction in stunting were the two key interventions, each accounting for around 32% of the lives saved during this period. Scaling up the direct diarrhea case management interventions from the current coverage levels in 2015 to achieve universal coverage levels by 2030 can save around 82 000 additional lives. If the universal targets for nutritional factors and WASH interventions can be achieved, an additional 23 675 lives can potentially be saved. CONCLUSIONS: While it is crucial to improve the coverage and equity in ORS use, an integrated approach to promote nutrition, WASH and direct diarrhea interventions is likely to yield the highest impact on reducing the remaining diarrheal deaths in under-five children.

Partnership Conference.

BACKGROUND: The Duke Global Health Institute (DGHI) was founded in 2006 with a goal to foster interdisciplinary global health education and research across Duke University and Duke Medical Center. Critical to achieving this goal is the need to develop and sustain strong international partnerships. OBJECTIVE: To host a conference with multiple international partners and strengthen existing relationships. METHODS: After a deliberate year-long planning process, DGHI convened a Partnership Conference with its international partners on the Duke University campus in conjunction with its 10th Anniversary Celebration. The Partnership Conference sought to promote an exchange of novel ideas in support of global health education and research, explore new collaborations in South-South relationships, and identify and facilitate pursuit of new educational and research opportunities. FINDINGS: A total of 25 partners from 10 countries and 46 DGHI faculty members participated in the 3-day event in October 2016. Activities included workshops on preselected research topics, educational symposia on novel teaching methods and harnessing technological advances, introduction of the Health Humanities Laboratory to prepare students and trainees for fieldwork, and discussions of research infrastructure and training needs. Surveys from visiting partners revealed a high degree of satisfaction. Proposed action items include methods to realize improved communications, enhancement of mutual education opportunities, support and mentoring to build local research capacity, and more exchange of faculty and students between partnering institutions. CONCLUSIONS: With careful planning from all parties, a multilateral partnership conference including both university and medical center faculty can be a productive forum for exchange on global health education and research. Sustaining such partnerships is vital to the success of global health scholarship.

Global hearing health care: new findings and perspectives.

In 2015, approximately half a billion people had disabling hearing loss, about 6·8% of the world's population. These numbers are substantially higher than estimates published before 2013, and point to the growing importance of hearing loss and global hearing health care. In this Review, we describe the burden of hearing loss and offer our and others' recommendations for halting and then reversing the continuing increases in this burden. Low-cost possibilities exist for prevention of hearing loss, as do unprecedented opportunities to reduce the generally high treatment costs. These possibilities and opportunities could and should be exploited. Additionally, a comprehensive worldwide initiative like VISION 2020 but for hearing could provide a focus for support and also enable and facilitate the increased efforts that are needed to reduce the burden. Success would produce major personal and societal gains, including gains that would help to fulfil the "healthy lives" and "disability inclusive" goals in the UN's new 2030 Agenda for Sustainable Development.

The President's Emergency Plan for AIDS Relief: from successes of the emergency response to challenges of sustainable action.

The President's Emergency Plan for AIDS Relief (PEPFAR) has made a major contribution to the reduction of the global HIV/AIDS burden. The program initially focused on rapidly scaling up treatment and prevention services in fifteen low-income countries, then transitioned to an approach that emphasizes sustainability, defined as the capacity to maintain program services after financial, managerial, and technical assistance from the United States and other external donors essentially ceases. Today, PEPFAR continues to expand its HIV prevention, treatment, and care activities while also supporting capacity-building initiatives, coordination efforts, and implementation science. The latter is research focused on improving service delivery, maximizing cost-effectiveness, and achieving public health impact. Recent advances in both scientific knowledge and the provision of prevention, treatment, and care services have bred cautious optimism about greatly reducing the spread of HIV. However, success will require a substantial increase in resources, strengthened health systems, renewed commitment to HIV prevention, and well-financed efforts to develop an effective HIV vaccine.

Perspective: global medicine: opportunities and challenges for academic health science systems.

Globalization is having a growing impact on health and health care, presenting challenges as well as opportunities for the U.S. health care industry in general and for academic health science systems (AHSSs) in particular. The authors believe that AHSSs must develop long-term strategies that address their future role in global medicine. AHSSs should meet global challenges through planning, engagement, and innovation that combine traditional academic activities with entrepreneurial approaches to health care delivery, research, and education, including international public-private partnerships. The opportunities for U.S.-based AHSSs to be global health care leaders and establish partnerships that improve health locally and globally more than offset the potential financial, organizational, politico-legal, and reputational risks that exist in the global health care arena. By examining recent international activities of leading AHSSs, the authors review the risks and the critical factors for success and discuss external policy shifts in workforce development and accreditation that would further support the growth of global medicine.

Surgical capacity building in Uganda through twinning, technology, and training camps.

BACKGROUND: Neurosurgical capacity is extremely deficient in East African countries where 27 neurosurgeons serve more than 250 million people. To build capacity, the Duke University Medical Center and New Mulago Hospital in Uganda applied a two-pronged twinning approach that placed usable surplus equipment in a developing country's National Hospital, combined with dedicated comprehensive surgical training camps. METHODS: Neurosurgery, anesthesiology, nursing, and clinical engineering personnel supported three training camps. More than 21 tons of essential equipment was delivered to New Mulago Hospital in Uganda. Data was collected during the 2-year period preceding and following the initiation of the program. RESULTS: During the 2 years after the program began, neurosurgery demonstrated a significant increase (180%) in the number and complexity of cases performed (p<0.0001). Multiple cases performed in a single day increased eightfold (p<0.0001), with utilization of elective operating room days improving from 43 to 98%. There was no change in the number of hospital admissions over the 4 years (p>0.1), but there was a dramatic increase in the overall number of procedures performed by all surgical specialties (106%, p<0.0001). CONCLUSIONS: Through a twinning program combining delivery of surplus equipment and training camps, capacity building was accomplished and maintained. The program not only built overall surgical capacity, it improved the efficiency and increased the complexity of operative cases performed at the National Hospital in Uganda. This program could serve as a model for twinning, capacity building, and training in other developing countries where surgical disparities are among the greatest.
