Nine behavioral and environmental risk factors contribute to a third of global cancer deaths. Lifestyle changes and environment modifications can prevent many types of cancer.
Researchers found that tobacco companies are using candy-like flavors and high-tech delivery devices to market new brands to young smokers. The study reveals that flavored cigarettes can promote youth smoking initiation by masking the harshness and taste of tobacco smoke.
The study found that more than 95% of HIV-infected people in resource-poor nations can benefit from combination ARV treatment, leading to improved CD4 counts, decreased viral load, and weight gain. The results underscore the importance of monitoring drug tolerability and toxicity to ensure patients' quality of life and adherence rates.
Eating one fish meal per week provides significant nutritional benefit, but decreasing fish consumption can lead to lost omega-3 fatty acids and increased risks of coronary heart disease and stroke. The study suggests that the government advisories may be doing more harm than good by limiting fish intake.
The survey found that 52% of Katrina evacuees had no health insurance coverage at the time of the hurricane. Many reported experiencing health problems or injuries as a result of the storm and were struggling to access necessary care, with 39% reporting they didn't receive help from any government agency or voluntary group.
A study combining genome scan data from 11 independent linkage studies found strong genetic signals on chromosomes 6 and 8 associated with bipolar disorder. The analysis involved over 1,000 families and 5,179 individuals from North America, Italy, Germany, Portugal, the UK, Ireland, and Israel.
A Harvard study found that adult occupational class has a significant impact on health outcomes, even after accounting for early childhood conditions and education level. Working-class twins were more likely to experience high blood pressure, cholesterol levels, and lower self-rated health compared to their professional counterparts.
A study of 3,558 US hospitals found that patients received inadequate care for six quality indicators, with performance varying by region, hospital type, and profit status. Hospitals in the Northeast and Midwest scored higher than those in the West and South, while not-for-profit hospitals outperformed for-profits.
Despite conflicting studies on obesity, most Americans believe it remains a serious public health issue. Approximately 75% of Americans rate obesity as extremely or very serious, and the majority think experts have accurately portrayed its health risks. However, there is mixed trust in scientific experts' advice on weight control.
Cellular behavior exhibits properties of both solid and fluid states, with researchers finding novel nanotechnologies that reveal the fundamental physical laws governing cell mechanics. This discovery offers a new perspective on mechanisms of disease, including airway narrowing in asthma and vessel narrowing in vascular disease.
A recent study found that NICU infants are exposed to high levels of DEHP, a phthalate linked to reproductive issues and other health problems. The study showed a direct correlation between the use of DEHP-containing medical products and elevated MEHP levels in infants' urine.
A Harvard study finds that diabetics experience impaired blood vessel function on days with high sulfate and black carbon particle pollution, increasing heart attack risk. The research highlights a biological mechanism linking particle pollution to cardiovascular disease.
A significant association was found between air pollution and an increased risk of ventricular tachyarrhythmias among patients with implanted cardioverter defibrillators. The risk was particularly high when particulate air pollution, black carbon, nitrogen dioxide, and sulfur dioxide were present.
Researchers identify two distinct cell types, macrophages and dendritic cells, that form the body's emergency response to foreign bacteria. These cells play a crucial role in developing protective immunity against leprosy and other diseases.
Medical schools have inconsistent standards for allowing industry sponsors to control research, including revising manuscripts, limiting investigator roles, and reviewing data. Some institutions prioritize public interest over sponsor interests, while others are more permissive, raising concerns about researchers' autonomy.
A study estimated the predicted probability of 12-month and lifetime IPV for patients presenting with smoking and problem drinking behaviors, helping clinicians identify at-risk patients. The study found that even women who didn't smoke or drink had a significant likelihood of abuse, highlighting the need for routine screening.
The report has had a positive impact on improving patient safety by changing healthcare views, enlisting support from stakeholders, and altering practices. Clinical effectiveness of safe practices implemented in hospitals show promising results, including reduced medical errors, adverse drug events, and cardiac arrests.
Research suggests that obesity can exacerbate asthma due to reduced lung function, chronic inflammation, and hormonal changes. The study found increased levels of pro-inflammatory hormones like leptin in obese individuals with asthma.
Research identifies cigarette smoking as a modifiable risk factor for the progression of multiple sclerosis. Patients who were current or past smokers were 3.6 times more likely to develop secondary progressive MS than those who had never smoked.
Researchers discovered a gene, Ipr1, on mouse chromosome 1 that influences innate immunity to tuberculosis and another intracellular pathogen, Listeria monocytogenes. The study suggests that the human equivalent of Ipr1, SP110, may play a significant role in determining tuberculosis susceptibility.
A Harvard School of Public Health study analyzed dietary habits and found no strong association between western or prudent diets and pancreatic cancer risk. Participants who adhered to the prudent diet had healthier lifestyle behaviors, suggesting individual dietary components may still play a role in risk.
A study by Harvard researchers suggests promoting cleaner charcoal production can prevent up to 2.8 million deaths and reduce greenhouse gas emissions by 45-66%. Transitioning from biomass fuels to petroleum-based fossil fuels offers the biggest health benefits, but is unlikely due to economic and infrastructure constraints.
A recent study published by Harvard researchers found that consuming acrylamide through diet does not increase the risk of breast cancer in women. The study, which analyzed data from over 43,000 participants, also showed no association between acrylamide intake and an increased risk of other cancers.
Men who were most physically active at start of study cut their risk by 50 percent, while strenuous activity in early adult life reduced risk by 60 percent. Physical activity was also linked to lower risk in women, although this relationship was not statistically significant.
