A recent Mount Sinai study found that Hispanic patients with stage I non-small cell lung cancer have a significantly lower five-year survival rate of 54% compared to white patients at 62%. This disparity is largely attributed to unequal access to surgical resection, as well as higher rates of advanced-stage diagnosis.
A randomized trial of 202 participants showed a 23% reduction in all-cause mortality, a 30% reduction in cardiovascular disease mortality, and a 49% reduction in cancer mortality. The study found that Transcendental Meditation reduces risk factors for heart disease and other chronic disorders.
A USGS study reveals that the world's most productive forests, which add new growth each year, have lower birth and death rates. However, if these rates suddenly stop or double, tree numbers would halve in just 30 years. The study suggests that environmental changes considered beneficial to forests may bring about unexpected changes.
Research reveals a parallel between global forest productivity patterns and tree birth and death rates. In contrast, highly productive tropical forests undergo rapid tree replacement cycles.

A study found that medical technologies in Brazil, such as increased antenatal visits and ultrasound scans, did not improve neonatal mortality rates, but rather led to an increase in pre-term births and low birthweight babies. This suggests that medical interventions may be offsetting the gains from improved maternal health.
A 14-year study published in Annals of Internal Medicine found that quitting smoking can add years to life. The study showed a significant reduction in death rates among participants who quit compared to those who continued to smoke.

The study involved over 1000 patients and found that EVAR was associated with lower 30-day mortality rates, but also led to more secondary procedures.
A U-M study found that hospitals meeting Leapfrog quality standards for high-risk surgeries can save thousands of lives. Implementing these standards would reduce mortality rates for procedures like open heart surgery and angioplasty.
A study found that states with mandated in-person license renewal laws had a lower death rate among drivers aged 85 and older. In-person renewal allowed for medical evaluations, which may lead to decreased fatality rates among this age group.

The excess cancer burden can be clearly linked to smoking, with significant declines in mortality rates observed when smoking declined.
The length of hospital stay for patients with acute myocardial infarction (AMI) has significantly shortened over the past few decades, from six weeks in the 1950s to less than one week today. Despite this decline, there is considerable variation in hospitalization duration among AMI patients.

The researchers estimated that 31,000 stroke-associated deaths and 17,000 deaths related to ischemic heart disease may have been prevented each year since fortification was implemented.
Research suggests that direct-quality indicators based on patient mortality are more effective in selecting high-performing hospitals for VLBW infants. The study found that hospitals with lower past mortality rates had significantly better outcomes, implying that volume-based standards may not accurately predict quality.
A recent study found that hospital procedural volume is only modestly associated with risk-adjusted CABG mortality rates, suggesting that other measures are needed to assess quality. Low-volume hospitals often achieve excellent outcomes despite operating on higher-risk patients.
A study developed a risk index to predict mortality in heart failure patients based on demographic and vital sign features, identifying low- and high-risk individuals. The model revealed that older age, lower blood pressure, higher respiratory rate, and hyponatremia are associated with increased mortality.
Women with COPD are accounting for an increasing number of deaths due to rising smoking rates and occupational exposures. The disease was previously thought to be a male-dominated condition, but recent studies have shown that women's lung health has improved significantly over the past few decades.
