The study, which followed 229 patients with schizophrenia for two years, suggests that these medications may be more effective in reducing violence.
A study published in Endocrine Practice found that continuous insulin monitoring and endocrinologist involvement did not increase the cost of treating diabetic patients undergoing CABG surgery. The protocol showed significantly better glycemic control, leading to shorter hospital stays and fewer deep sternal wound infections.
The prevalence of age-related macular degeneration (AMD) is estimated to be 1.47% in the US population aged 40 and older, with an expected increase to 2.95 million cases by 2020. The risk of AMD increases dramatically with age, especially among white individuals.
Researchers found that patients with kidney transplants from donors aged 55-79 had comparable allograft survival rates as those from younger donors. The study also revealed that older recipient patients may benefit from receiving kidneys from older deceased or living donors, particularly those facing prolonged waiting times on dialysis.
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 Eye Diseases Prevalence Research Group has conducted large, population-based studies to determine the prevalence of cataract, age-related macular degeneration, diabetic retinopathy, and other eye disorders. The estimates are likely to be reliable and available without waiting many years and spending tens of millions of dollars.
Researchers found that nearly one-quarter of hospitalized individuals with current alcohol use disorders had undetected diagnoses, and only half of detected cases received intervention or treatment referral. The study highlights the need for routine screening and education among medical professionals to address this issue.
A recent UC Berkeley-led study found that vitamin C supplements can decrease levels of C-reactive protein (CRP) by 24% in healthy adults. CRP is a biomarker of inflammation linked to chronic diseases like heart disease and diabetes.
Diabetic retinopathy, a leading eye complication in people with type 1 diabetes, affects nearly 774,000 Americans under age 30. The prevalence is highest among 40-49 year olds and older, driven by aging US population.
Researchers found that embryonic keratinocytes differentiate into skin cells much sooner than cells after birth. The study suggests a higher commitment to differentiation in embryonic skin cells, which may apply to other epithelial tissues.
A commentary by Pauls and Downie argues that mandatory reporting could erode trust between patients and physicians. Ovens, writing on behalf of the OMA's Section on Emergency Medicine, counters that exceptions exist to protect patient confidentiality while maintaining public safety.
A study of police officers in Australia found that they rate the accuracy of a profile more when they think it was written by a professional profiler, regardless of its actual content. The researchers suggest that this bias can lead to false positives and undermine the effectiveness of profiling.
The study found that approximately one-third of people older than 40 experience vision disturbances, with myopia being the most prevalent eye disorder. The estimated prevalence rates for myopia vary by region, affecting about one in four people in the US and Western Europe, and one in six Australians.
A study found that over a third of patients are interested in reading their medical records, with the most common reasons being to understand their condition and be more involved in healthcare. Patients who want to review their records are often those seeking alternative health information and have concerns about errors in care.
A study published in Journal of Clinical Oncology found that extended lymph node dissection does not increase long-term survival among gastric cancer patients, potentially increasing morbidity and hospital mortality. The procedure may only be beneficial if safe and effective alternatives can be developed.
A study by Ohio State University suggests that rewards for high-performing schools and strong district support are key to successful accountability systems. Research found that sanctions led to teacher disengagement and ineffective professional development.
Researchers developed a new method to alter gene expression levels without disrupting essential control elements. This technique uses the 3' untranslated region (UTR) to influence protein production, allowing for predictable and controlled changes in gene expression.
A majority of US immigrant adults perform at the lowest literacy level, with those having higher literacy proficiencies showing better labor market outcomes and wages.
A study examining health care benefits and disadvantages when physicians treat themselves found that even doctors who disapprove of self-doctoring may do so due to lack of thought. Benefits include convenience and control, but also risks such as delayed care and ignoring medical instincts.
A new AAN guideline has resolved debate surrounding the role of Patent Foramen Ovale (PFO) in stroke risk. The guideline found no evidence to support or refute closing PFOs, but notes an increased risk for younger patients with both a PFO and atrial septal aneurysm (ASA). Further research is needed to determine the best treatment options.
