MedicalResearch.com: What is the background for this study?
Response: Eczema (also known as atopic dermatitis) has become increasingly common over recent decades, especially in industrialized countries, suggesting that environmental or lifestyle factors like diet could impact rates of disease. It is well established that sodium, consumed primarily in the form of salt, increases the risk of hypertension and heart disease through pro-inflammatory mechanisms. The role of sodium on other chronic inflammatory conditions like eczema has been less well-studied.

MedicalResearch.com: What is the background for this study?
Response: Olive oil is rich in monounsaturated fats and contains compounds with antioxidant activity that may play a protective role for the brain. Olive oil as part of a Mediterranean diet appears to have a beneficial effect against cognitive decline. Higher olive oil intake was previously associated with a lower risk of cardiovascular disease and mortality. But its association with dementia mortality was unknown.

Response: Sugar-sweetened beverages (colloquially known as SSBs), which include sodas, fruit drinks, sports drinks, energy drinks, and sweetened coffee drinks, are the leading source of added sugars in the American diet, according to the CDC. They are associated with serious negative health outcomes, including type 2 diabetes, obesity, heart disease, kidney disease,

Response: Adding salt to foods is a behavior reflecting long-term preference to salty diets. High sodium intake is a major risk factor for chronic kidney disease.
In our previous studies, we have found that adding salt to foods at the table is related to various disorders including cardiovascular diseases, diabetes, and mortality.

MedicalResearch.com: What is the background for this study? Can teeth be safely brush in patients who are comatose, intubated or have NG tubes?
Response: Pneumonia is thought to occur when secretions from the mouth get into the lungs. Since there are many microbes in the mouth, there’s a risk that secretions from the mouth that get into the lungs will lead to pneumonia. Toothbrushing may lower this risk by decreasing the quantity of microbes in the mouth.
It is indeed safe and appropriate to brush the teeth of someone who is comatose, intubated, or who has an NG tube. Indeed, our study found that the benefits of toothbrushing were clearest for patients receiving mechanical ventilation.

MedicalResearch.com: What is the background for this study? Would you briefly explain the symptoms/course of pilonidal disease?
Response: Pilonidal disease is relatively common and affects up to 1% of the population starting in adolescence and up until young adulthood. Pilonidal disease occurs when cysts or sinuses form between the buttocks. It is believed to be an inflammatory reaction to hair or debris that gets caught in the crease of the buttocks. Risk factors for the condition include a sedentary lifestyle, hygiene and obesity.

MedicalResearch.com: What is the background for this study?
Response: Apolipoprotein E (APOE)*2 and APOE*4 are, respectively, the strongest protective and risk-increasing, genetic variants for late-onset Alzheimer disease. As such, one’s APOE genotype is highly relevant towards clinical trial design and Alzheimer’s disease research. However, most insights so far are focused on the associations of these APOE genotypes with Alzheimer’s disease risk in non-Hispanic white individuals.
One important aspect of our work is that we really increased sample sizes for non-Hispanic Black, Hispanic, and East Asian individuals, so that we now have better understanding of the associations of APOE genotypes with Alzheimer’s disease risk in these groups. In complement, we also did the largest investigation to date on the role of ancestry on the associations of APOE genotypes with Alzheimer’s disease risk. The scale of our study was thus a critical factor in generating novel insights.

Response: Decline in various aspects of cognitive function, such as memory, executive function, and multitasking ability is common as we age. The rate and extent of decline varies among older adults but approximately 20% of those aged 65+ will experience clinically relevant mild cognitive impairment, which places them at increased risk of progressing to Alzheimer’s disease or related dementias. It is also associated with decreased mobility, increased risk of falls and impaired capacity for complex activities of daily living.

Response: We conducted this study to inform school COVID-19 policies.
The main findings are that the median duration of infectivity after a positive COVID-19 test in children is 3 days. The median duration of infectivity does not vary with vaccination.

MedicalResearch.com: What is the background for this study?
Response: Staphylococcus aureus commonly causes infections in ICUs. One approach to preventing these infections is using nasal mupirocin plus chlorhexidine gluconate (CHG) bathing for ICU patients. This practice is known to prevent methicillin-resistant Staphylococcus aureus (MRSA) infections and all-cause. bloodstream infections. This practice has been broadly adopted in ICUs in the US, but adoption of mupirocin as a universal topical antibiotic has been slowed by concerns for engendering mupirocin resistance.
This cluster-randomized trial in adult ICUs was conducted to assess whether universal nasal antiseptic povidone-iodine (iodophor), to which minimal S. aureus resistance is expected, was an acceptable alternative to universal nasal mupirocin for reducing S. aureus and MRSA clinical cultures in the setting of daily CHG bathing. Those who received chlorhexidine (CHG) bathing with mupirocin had an 18% reduction in risk of Staphylococcus aureus clinical cultures and a 15% reduction in risk of methicillin-resistant
