MedicalResearch.com: What is the background for this study?
Response: Colorectal cancer is the third leading cause of cancer deaths in the United States, yet about a quarter of people ages 50 to 75 have never been screened for this devastating disease. Fortunately, we know that screening for colorectal cancer is effective and saves lives. New science about colorectal cancer in people younger than 50 years old has enabled us to expand our previous guidelines to recommend that all adults ages 45 to 75 be screened for colorectal cancer to reduce their risk of dying from this disease.

MedicalResearch.com: What is the background for this study? What are its benefits?
Response: DHA is an omega-3 fatty acid. Good food sources include some types of seafood (e.g., salmon, tuna, trout) and chicken eggs. Persons in the USA and in much of the developing world consume little dietary DHA. DHA supplements in pregnancy have been linked to lower risk of preterm birth for 20 years, especially early preterm births (<34 weeks gestation). For about 10 years, prenatal supplements with about 200 mg DHA have been readily available in the USA, however, no study has asked if this amount of DHA is optimal to reduce early preterm birth. Participants were given a supplement of 1000 mg or 200 mg DHA beginning before 20 weeks gestation using an adaptive randomization that periodically assigned more participants to the group with the fewest early preterm births.

MedicalResearch.com: What is the background for this study? What is the significance of this oral biofilm?
Response: Dental caries is one of the most common and costly biofilm-dependent diseases that afflict children and adults worldwide. Particularly, Early Childhood Caries (ECC) is a hyper-virulent type of chronic tooth decay that most frequently afflicts underprivileged preschool children. The onset and progression of carious lesions in ECC are rapid and aggressive, causing rampant destruction of the smooth surfaces of teeth.
ECC is painful and often requires surgical procedure under general anesthesia, while current treatment modalities are inefficient and recurrence of ECC is common. Notably, interactions between a fungus, Candida albicans, and a bacterium, Streptococcus mutans, have been known to play important roles in the pathogenesis of dental caries.
Thus, we attempted to strategically develop a targeted measure to effectively prevent cross-kingdom interactions and subsequent biofilm development.

Response: Hypertension affects nearly half of all adults in the United States and is a major risk factor for many serious health conditions. Fortunately, by screening all adults for hypertension, clinicians can improve their patient’s health. The Task Force continues to recommend screening all adults for hypertension so that they can get the care they need to help prevent health conditions such as heart attack, stroke, and kidney failure.

MedicalResearch.com: What is the background for this study?
Response: Early-onset colorectal cancer (EO-CRC, age <50 years at diagnosis) is rapidly rising in the US since the mid-1980s, with an unclear understanding of its etiology and contributors to the rise. Sugar-sweetened beverages (SSBs) exert adverse metabolic repercussions throughout the life course, including insulin resistance and inflammation. Higher SSB intake can induce obesity, which has been linked to risk of EO-CRC. A recent experimental study also suggests that high fructose corn syrup, a primary sweetener in SSBs, may promote colon tumor growth, independent of metabolic dysregulation. In the US, SSB consumption has dramatically increased during the 2nd half of the 20th century, and adolescents and young adults have been the heaviest SSB drinkers across all age groups. Thus, we expect SSBs may be an emerging risk factor for EO-CRC and likely contribute to the rising incidence of EO-CRC.

MedicalResearch.com: What is the background for this study? Would you describe the system? Does it use dermatoscopic images?
Response: Dermatologic conditions are extremely common and a leading cause of morbidity worldwide. Due to limited access to dermatologists, patients often first seek help from non-specialists. However, non-specialists have been reported to have lower diagnostic accuracies compared to dermatologists, which may impact the quality of care.
In this study, we built upon prior work published in

MedicalResearch.com: What is the background for this study?
Response: Our study was really guided by a key question: does Covid-19 in pregnancy increase the risk of adverse maternal and neonatal outcomes as compared with pregnant women who do not have the infection?
The question is highly relevant because of the known deleterious effects of other coronavirus infections in pregnancy, e.g. SARS (severe acute respiratory syndrome) and MERS-CoV (Middle East respiratory syndrome coronavirus).
In order to answer this question we undertook this multinational cohort study.

MedicalResearch.com: What is the background for this study? Which vaccines did you evaluate?
Response: Prior studies from several groups including our own have found T cell cross-recognition of peptides from SARS-CoV-2 and the common cold coronaviruses.
We asked whether as a result of this cross-reactivity, immunization with the SARS-CoV-2 vaccine would also enhance T cell responses to the common cold coronaviruses.
Prior studies also suggested that antibodies elicited from the mRNA vaccines had a reduced ability to neutralize the emerging variants of concern.
Most of the study participants had received the Pfizer vaccine, but a few had received the Moderna vaccine.

MedicalResearch.com: What is the background for this study?
Response: Toilet flushing can generate large quantities of microbe-containing aerosols depending on the design and water pressure or flushing energy of the toilet. Based on previous reports, a variety of different pathogens which are found in stagnant water or in waste products (e.g., urine, feces, and vomit) can get dispersed widely via such aerosolization, including the legionella bacterium responsible for causing Legionnaire’s disease, the Ebola virus, the norovirus which causes severe gastroenteritis (food poisoning), and the Middle East Respiratory Syndrome coronavirus (MERS-CoV).
Based on previous reports, such airborne dispersion is suspected to have played a key role in the outbreak of viral gastroenteritis aboard a cruise ship, where infection was twice as prevalent among passengers who used shared toilets compared to those who had private bathrooms. Similarly, transmission of norovirus via aerosolized droplets was linked to the occurrence of vomiting or diarrhea within an aircraft restroom, as passengers and crew who got infected subsequently were more likely to have visited restrooms than those that were not infected. The participants in the study reported that all of the restroom surfaces appeared to be clean, which indicates that infection is likely to have occurred via bioaerosols suspended within the restroom.
Although many of these studies blamed flush-generated aerosols for disease outbreak, a limited number of them quantified the presence of such aerosols. Consequently, we decided to conduct this study to demonstrate the spike in aerosol concentrations following flushing.

Response: Atherosclerotic cardiovascular disease (ASCVD), defined as ischemic heart disease (IHD), ischemic cerebrovascular disease (ICVD), or peripheral arterial disease (PAD), is the leading cause of death globally. Particularly in young ASCVD patients, secondary prevention with antiplatelet therapy and statins are extremely important in reducing disease burden.
