A population-wide study in Chile shows that a mix-and-match approach to booster vaccination provides the best protection against COVID-19. The study found that heterologous booster vaccines, such as Pfizer-BioNTech or Astra Zeneca, were more effective than using the same vaccine for all three doses.
Unemployment rates for people with disabilities increased in March, while those without disabilities still lag behind pre-pandemic levels. Despite this, people with disabilities are continuing to outperform their non-disabled counterparts in the labor market.

The studies revealed that language barriers, economic status, and cultural differences contribute to these gaps in care.
A new study from Brown University's Policy Lab found that text-message vaccination campaigns work better when sent early, as all state residents ages 16 and up had been eligible for a shot four weeks before the campaign. Despite this, the messages' ineffectiveness was due to poor timing rather than the content.
The American marten study found that monitoring the species has an 'umbrella effect' on 11 other mammals, detecting population declines. However, habitat loss and climate change threaten the marten's survival. The researchers developed a monitoring protocol for the winter season to detect protected species.

A new study published in Clinical Nutrition found that drinking less than the UK's recommended 14 units of alcohol per week increases the risk of cardiovascular events. Moderate alcohol consumption is associated with a 23% increased risk of suffering a cardiovascular event for every additional 1.5 pints of beer consumed.
A new study found a strong association between social determinants of health and obesity rates, with higher SDOH burden leading to increased obesity prevalence. The study analyzed data from nearly 165,000 adults in the US and found that middle-aged and non-Hispanic Black adults were more likely to be overweight or obese.

The study suggests that patients may be missing treatments for acute illnesses and delaying preventive care.
Scientists identified 46 metabolites linked to coronary heart disease among Black Americans, which were also found in a multi-ethnic population. These biomarkers may serve as better markers of disease for the general population than traditional risk factors.
A study of over 800 hospitals found that people experiencing incarceration or homelessness had increased COVID-19 hospitalization rates and longer hospital stays compared to the general population. This highlights the vulnerable status of these groups during the pandemic.
The job numbers for people with disabilities remained above pre-pandemic levels in December, according to the National Trends in Disability Employment (nTIDE) report. The employment-to-population ratio for working-age people with disabilities decreased slightly from 34.6 percent in November to 33.6 percent in December.
A longitudinal study of male prisoners' religious beliefs found that stable or increasing religiosity did not improve reentry-related outcomes. In fact, many men with decreasing religious beliefs struggled to reintegrate into society due to structural barriers and substance use.
A phase 3 trial has shown that one dose of the Ad5-nCoV COVID-19 vaccine is highly effective against severe disease, with an efficacy rate of 91.7% at 28 days post-vaccination. The vaccine has also been found to be safe, with no serious vaccine-related adverse events or deaths reported among trial participants.
A survey study found links between problematic smartphone use and low sense of control, fear of missing out (FOMO), and repetitive negative thinking during the COVID-19 pandemic. The study suggests that physical activity and mindfulness practices may help reduce such use.
Researchers developed a fair-diverse allocation optimization framework to optimize the distribution of COVID-19 vaccines, treatments, and testing supplies. The model aims to get limited resources to the most vulnerable subgroups while ensuring fairness and diversity, independent of demographic background.
A recent study found that a substantial decline in lung cancer deaths is associated with earlier diagnosis of lung cancer through increased screening via computed tomography (CT) and follow-up scans. This approach can lead to surgical interventions, which can often be curative for precancerous nodules.
A University of Cambridge-led study found that rising housing prices can significantly increase 'openness' among US residents within a few years. This trait captures levels of curiosity and creativity.
