A study by Duke University Medical Center found that agreements between academic medical centers and industry sponsors rarely include provisions to protect researchers' independence, access to data, and editorial control. This can lead to compromised scientific integrity and a lack of transparency in clinical trials.
A patient's view on clinical trials highlights the importance of thorough explanations, confidentiality, and compassionate communication. Sylvia Achin emphasizes that patients risk losing their priorities, relationships, and even support when faced with a life-threatening disease like cancer. Effective communication can help alleviate ...
Key findings from the ESMO Congress emphasize the need for better care and communication in cancer treatment. Patients must be informed and involved in their treatment decisions, while healthcare professionals should prioritize empathy and understanding. A European cancer patient coalition is proposed to amplify patients' voices.
A randomized, double-blind trial found that magnesium supplementation had no effect on 30-day mortality in patients with acute STEMI. The study's results support current coronary care practice and suggest that routine administration of intravenous magnesium is not indicated.

A study has identified genetic markers that can help guide clinical trials for anti-Alzheimer drugs, potentially leading to the development of a more manageable pool of individuals at high risk. These markers may allow researchers to winnow down the general population and focus on those with relatively higher risk for Alzheimer's disease.

The FDA has approved Actonel 35 mg once-a-week for the treatment and prevention of postmenopausal osteoporosis, showing a significant increase in lumbar spine bone mineral density at 12 months. The study found that once-a-week dosing is therapeutically equivalent to daily dosing.
A survey of oncologists reveals that most enroll patients in clinical trials for access to advanced treatment options rather than advancing future therapy. This challenges the conventional view that research is conducted primarily for scientific progress and improving treatments.
A recent study has challenged the long-held notion that African-Americans with prostate cancer have a poorer prognosis than their white counterparts. Researchers found that, when treated within clinical trial settings, African-American patients survived for an average of 15 months, comparable to 14-month survival rates for whites.

The International Breast Cancer Intervention Study (IBIS) found that tamoxifen reduced breast cancer incidence by 38% in healthy high-risk women. However, the benefits of tamoxifen for prevention in these women are unclear due to potential side effects and risks.
Researchers found that elderly patients are less likely to undergo invasive procedures such as bypass surgery and angioplasty after age 75. Despite a decline in procedure use among older adults, many elderly patients remain willing to consider these treatments when recommended by their physicians.
The European CanCer Organisation's Dr Robin Wilson says current evidence supports breast cancer screening's effectiveness in reducing mortality, but acknowledges drawbacks such as false positives and anxiety for women. Countries with full national screening programmes have seen significant benefits, including improved quality of care.
A study by Duke University researchers found that poor patients are more than twice as likely to die of severe heart disease compared to those with higher incomes. After adjusting for differences in treatment, poverty remained associated with a worse outcome, suggesting that post-hospital factors such as smoking and non-adherence to me...
The Swedish trials indicate a significant reduction in breast cancer mortality among women given mammography screening, with the greatest benefit seen in age groups 60-69 years. The trials found no significant difference in death from all causes between screening and control groups.

A Dartmouth study found biases in cancer screening trials that may have overestimated its benefits, suggesting a need for alternative mortality analysis methods. The research recommends using all-cause mortality alongside disease-specific mortality to ensure accurate assessment of screening's value.
A study found that two forms of bias in cause-of-death classification affect the results of randomized trials on cancer screening. Sticky-diagnosis bias biases against screening, while slippery-linkage bias biases in favor of screening. The authors suggest using all-cause mortality to accurately assess the value of screening.
A new prostate cancer vaccine developed at Duke University Medical Center has shown promising results, boosting the patient's immune system to fight cancer. The vaccine, made from the patient's own dendritic cells, causes no adverse side effects and activates T cell responses against tumor cells.

A recent study published in the New England Journal of Medicine found that predicting preterm birth remains challenging due to low predictive value of current tests such as ultrasound and fetal fibronectin. The study suggests that prematurity in America is on the rise, with a 23% increase in premature births since the 1980s.
Researchers at Georgetown University Medical Center are conducting a clinical trial to assess the effectiveness of venlafaxine HCI on post-traumatic stress disorder (PTSD). The study compares three treatment options: Effexor XR, Zoloft, and a placebo. Results may provide new hope for individuals suffering from PTSD after the 9/11 attacks.

A new nuclear medicine procedure has received preliminary approval for a clinical trial to diagnose inhalation anthrax in its earliest stages. The technique uses a 99mTc-labeled monoclonal antibody to detect the infection before other diagnostic tests can, enabling early treatment and reducing long-term antibiotic use.
Exanta shows comparable efficacy to warfarin in preventing stroke in patients with atrial fibrillation, with the added benefit of no dose titration or routine coagulation monitoring. The THRIVE programme also highlights Exanta's promise in treating venous thromboembolism.
A Canadian study found that only 11% of critically ill patients in ICUs have explicit directives guiding resuscitation. The study identified factors associated with DNR directives, including age and patient condition.
Researchers led by Robert E. Braun analyzed gene expression after adenovirus delivery using both in vitro and in vivo studies. The study found no infection of reproductive stem cells, supporting the safety of adenovector use in cardiovascular therapy.
A new study found that 71% of adult cancer patients knew they might not benefit directly from participating in clinical trials, while less than 40% recognized potential risks or discomfort. Despite this, patients were highly satisfied with the informed consent process and reported no pressure from physicians.
A new Stanford University study analyzed the costs and benefits of two treatments: implantable cardioverter defibrillators (ICDs) and the drug amiodarone. ICDs were found to be the most effective in preventing sudden cardiac death, but also came with the highest costs. Amiodarone produced intermediate benefits and costs.
Results from two independent studies show omega interferon's antiviral effect against all HCV genotypes, reducing virus to undetectable levels. The treatment also appeared to be well-tolerated by patients, with progressive anti-hepatitis C effects reported.
The top countries in academic paper production are US, Italy, UK, Japan, and France. The study analyzed papers published between 1995-1999 and found that North America produced more phase I studies while Europe dominated phase III studies. Italy's performance was attributed to its large number of physicians involved in cancer treatment.
A new study published in New England Journal of Medicine found that age alone should not determine whether an older patient is offered chemotherapy after surgery for treatment of stage II and III colon cancer. The study showed a significant reduction in death risk and improved survival rates among patients over 70 with the disease.
