Response: The NHS Bowel Cancer Screening Programme provides 2 yearly screening to men and women aged 60-74, and it is in the process of reducing the starting age to 50 years. The screening method is faecal immunochemical testing (FIT), in which the screenee places a small sample of faeces in a container and mails this back to the lab, which tests the sample for haemoglobin, as bleeding can be a sign of cancer. The screenee is invited for colonoscopy if the level of haemoglobin is higher than 120 micrograms per gram. The system is under considerable pressure as there are limited colonoscopy resources, the programme is working towards a lower age at starting screening and we are still dealing with the backlog caused by the COVID-19 pandemic, and there may be a need to reduce the intensity of screening in order that the colonoscopy services can cope.

Response: Gestational diabetes is a growing and significant health problem worldwide for women affected and their babies. Treatment of gestational diabetes improves maternal and infant health but it remains unclear what degree of maternal hyperglycaemia should be used to make the diagnosis. Because of this uncertainty, recommended diagnostic criteria vary around the world.
The GEMS randomised trial assessed whether use of lower glycaemic diagnostic criteria, recommended by the International Association of Diabetes and Pregnancy Study Groups would improve perinatal health, without increasing maternal risks, compared to use of higher criteria, and to assess the effects on use of the health services.

Response: Small (< 6 mm) kidney stones are common and often are asymptomatic. Do you do surgery or wait for them to cause a problem? Or specifically here if you are getting surgery already for other stones that are causing a problem do you take the time and possibly extra risk of cleaning out the small stone in the kidney or in the other kidney?

MedicalResearch.com: What is the background for this study? Would you tell us a little about aldosterone?
Response: “Recent randomized, controlled trials have shown that a drug called finerenone is effective in delaying CKD progression and adverse cardiovascular outcomes in patients with chronic kidney disease and diabetes. However, the role of aldosterone in this process was not directly investigated and levels of the hormone were not measured,”
“Since excessive levels of aldosterone is common, yet mostly unrecognized, we hypothesized that one reason why finerenone was effective in lowering the risk of CKD progression was that it was treating unrecognized high concentrations of the hormone.”
To study this we investigated the associations between aldosterone concentrations in the blood and kidney disease progression among 3680 participants in the Chronic Renal Insufficiency Cohort study, which ran in seven clinics in the US between 2003 and 2008. The participants were aged between 21 and 74 years old.
Aldosterone is a steroid hormone secreted by the adrenal glands, which sit above the kidneys. Its main role is to regulate salt and water in the body, and so it plays a central role in controlling blood pressure. Too much of it can lead to high blood pressure, cardiovascular and kidney diseases.

MedicalResearch.com: What is the background for this study?
Response: There are many cancers that both men and women can develop, specifically those that do not affect the reproductive tract. Men have higher rates of these nonreproductive cancers than women. There are only two nonreproductive cancer types that are more common in women: thyroid and gallbladder. Historically, we have thought this is because women are less likely to smoke or drink and are more likely to eat well and exercise than men.
This study sought to examine the sex bias in cancer incidence after controlling for those lifestyle factors to see if this explained the male predominance in cancer.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Heart attacks and strokes are the number one killer of adults in the United States. Based on the evidence we reviewed, the Task Force found that some people would benefit from counseling interventions to support their cardiovascular health, however the overall benefits are small. For that reason, we continue to recommend that healthcare professionals decide together with their patients who do not have cardiovascular disease risk factors whether counseling interventions on healthy diet and physical activity might help them prevent heart attacks and strokes. This is a C grade recommendation.

MedicalResearch.com:? What are the main findings?
Response: Osteoporosis is a major problem among elderly and malnourished people. Calcium, Vitamin D and Vitamin K are beneficial for bone health. Vitamin D stimulates calcium absorption and studies have shown that poor Vitamin K status intake is linked to low bone mass. Osteocalcin (OC) is a protein hormone found in the blood in activated and inactivated form. The activated form of Osteocalcin (cOC) binds calcium to bone tissue and plays an important role in regulating the metabolism. In addition, low levels of cOC are associated with insulin resistance, diabetes, and metabolic syndrome. It is desirable to have largest possible uOC, and vitamin K2 central in this process. The most important vitamin K2 variants in Jarlsberg® are the long-chain MK-7, -8, -9 and -9(4H), where lactic acid bacteria produce the first three, while MK-9(4H) is produced by Propionibacterium freudenreichii. The latter bacterium also produces the substance "1,4-dihydroxy-2- naphthoic acid" (DHNA), which has previously been shown to increase bone density in experimental mice. Two previous studies related to Jarlsberg® intake have been published:
The BMJ-study3: The central variables measured in this study were the serum bone turnover markers (BTM); tOC and cOC, procollagen type 1 N-terminal propeptide (PINP) and serum cross-linked C- telopeptide type I collagen (CTX). Additionally, Vitamin K2 and Vitamin K status, serum calcium and serum magnesium were recorded together with the development in glycated hemoglobin (HbA1c), lipids and protein turnover. The participants in the study were randomly divided into two groups. One group of 41 healthy volunteer women of childbearing age ate 57 grams of Jarlsberg® per day and the other group of 25 women ate 50 grams of Camembert for 6 weeks. The Camembert was manufactured with a starting culture not producing Vitamin K2. The fat, protein, and energy content of the daily consumption of Jarlsberg® and Camembert is approximately the same. After 6 weeks, Camembert was replaced with 57 grams of Jarlsberg® per day for another 6 weeks.

Response: Younger age at menopause is a possible risk factor for cardiovascular diseases. However, data on the association among premature menopause, age at menopause, and the risk of heart failure and atrial fibrillation are lacking. We aimed to examine the association of premature menopause and age at menopause with the risk of heart failure and atrial fibrillation.

Response: Heart failure is a common and incurable disorder that is known to arise from many different underlying causes. By exploiting a new technology, single nuclear transcriptional analyses, we aimed to define molecular profiles in human hearts tissues that were obtained from patients with different genetic and non-genetic causes of heart failure.
Our goal was to determine if there were distinctive signatures that could provide new opportunities to develop precise treatments, based on the specific cause of heart failure.

Response: Response: Current CDC COVID-19 isolation guidance allows for ending isolation after day 5 for non-immunocompromised individuals if they are afebrile and with improving symptoms, or if the individual is asymptomatic from the start. It has been proposed that rapid antigen tests (RATs) may assist in determining when individuals are no longer infectious. Specifically, a negative test would be potentially reassuring for an individual not being transmissible, while a positive test could be suggestive of continued infectiousness. However, there is little data about use of RATs in this particular setting and how they may correlate with ongoing risk of transmission as they were developed to be used during the initial diagnosis of infection, not in the later phase.

MedicalResearch.com: What is the background for this study?
Response: As a hospital-based general internist, I often see patients in the emergency department after an episode of syncope. Syncope is a medical term for suddenly losing consciousness (the public generally knows this as “fainting”). As you can imagine, fainting out of the blue can be very unnerving. Patients and clinicians worry that it may happen again and wonder whether it’s safe to drive. The first time I was asked this question, I remember scouring the research literature for an answer and not finding any robust evidence to guide my advice to patients.

MedicalResearch.com: What is the background for this study?
Response: Since April 2022, both the UK and US have changed their COVID-19 isolation and testing policies. The impact these changes in the guidance and vaccination on community-acquired COVID-19 caused by recent SARS-CoV-2 variants of concern (VOC) has not been fully tested, including infections with BA.2. We aimed to characterise both symptoms and viral loads over the course of COVID-19 infection in otherwise-healthy, vaccinated, non-hospitalised adults, to assess whether current guidance remains justified. All participants were included in the UCLH-Crick Legacy study, a prospective, observational cohort study of otherwise healthy adults who have been taking part in regular workplace testing for SARS-CoV-2 in London
We sent swabs by same-day courier every other day to all adults who reported a positive PCR or lateral flow test to the study team up to day 10 after the start of each infection. We confirmed which variant caused the infection by PCR and sequencing. All participants completed linked symptom diaries.
We compared symptoms and changes in the amount of virus detected in the nose and throat during infection between study participants reporting COVID-19 caused by VOCs Delta and Omicron BA.1 and BA.2. We then analysed how many of our participants would meet current UK/US isolation guidelines.

MedicalResearch.com: What is the background for this study? Where is blue light commonly found?
Response: Our study in short-lived model organism Drosophila revealed that cumulative, long-term exposure to blue light impacts brain function, accelerates the aging process and significantly shortens lifespan compared to flies maintained in constant darkness or in white light with blue wavelengths blocked.
Blue light is predominantly produced by the light-emitting diodes (LEDs); it appears white due to the addition of yellow fluorescent powder which is activated by blue light. LEDs has become a main source of display screens (phones, laptops, desktops, TV), and ambient lights. Indeed, humans have become awash in LEDs for most of their waking hours.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: There is undoubtably a lot of enthusiasm for psychedelics as therapeutic tools right now both in research and more broadly; however, there are still so many questions that need to be answered. It has been established that SNPs are clinically relevant when considering how patients may respond to various atypical antipsychotic drugs, so we wanted to see if they also could impact psychedelic assisted treatment strategies.
What we found is that genetics do matter; namely, our results indicate that patients with different genes will react differently to psychedelics.

Response: The U.S. government funds the National Health and Nutrition Examination Survey (NHANES), which is an ongoing surveillance study on the health and nutritional status of people living in the U.S. What is special about NHANES is it’s designed to be nationally representative and it uses objective measurements, so we’re more confident that this accurately reflects the health of the country. For this paper, we looked at the most recently released data to see how many children in the U.S. have obesity, meaning they’re above the 95th percentile for height and weight based on their age and sex. We extracted data from 2011 to 2020, which includes nearly 15,000 children and adolescents and is the most recently available data prior to the March 2020 COVID-19 shutdown when NHANES paused.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Osteoporosis is a major public health problem. Although supplemental vitamin D has been widely used to reduce the risk of fractures in the general population, studies of the effects of vitamin D on fractures, the most important bone health outcome, have been conflicting.
Randomized controlled trials, the highest quality studies, from around the world have shown benefit, no effect, or even harm of supplemental vitamin D on risk of fractures. Some of the trials used bolus dosing, had small samples sizes or short study duration, and co-administered calcium. No large RCTS of this scale tested whether daily supplemental vitamin D (without co-administration with calcium) prevented fractures in the US population.
To fill these knowledge gaps, we tested the hypothesis in this ancillary study to VITAL, whether daily supplemental vitamin D3 reduced the risk of incident total, non-spine and hip fractures in women and men in the US.
Stress might be something that isn’t new to you. Stress can come from a lot of things. You might have problems financially, or you might be struggling with a lot of sleep deprivation, especially if you are the pregnant person in your relationship. People might joke about you enjoying the sleep that you are getting now because it won’t last forever, but the chances are, you aren’t getting nearly enough sleep as it is already.
This is a period filled with highs and lows, especially if the due date is coming around the corner and you are struggling with making sure everything is ready on time. Stress is damaging to the baby too, so if your pregnant partner isn’t your top priority (which it absolutely should be through all of the pregnancy and newborn stages) you should switch it around so they are at the top of your list whenever they need anything.

Response: My colleagues and I have had a long-term interest in carrying out studies in people with hereditary cancer as a model for cancer in the general population. Here we studied people with Lynch syndrome who have an inherited defect in one of the genes encoding the DNA mismatch repair system. Because of this, they accumulate DNA damage faster than the general population and are prone to early cancers at several sites around the body.
In the CAPP2 Study, we randomised almost 1000 people with Lynch syndrome to either resistant starch or to an ordinary corn-starch placebo.

Despite increased efforts to recruit diverse medical trainees, there remains a large chasm between the racial/ethnic and socioeconomic composition of the patient population and that of the physician workforce.
Molluscum DermNet image[/caption]
Response: Molluscum Contagiosum (MC) is an infection caused by molluscipoxvirus. It is difficult to study since the virus only survives in human skin, and therefore there isn’t an animal or cell model to study potential treatments. Molluscum lesions appear as raised, domed shaped skin-colored lesions and can occur anywhere on the body but are most common on the face, neck, arms, legs, and abdomen. Sometimes there are few lesions, but clusters of several lesions can appear. Children are the most likely to get molluscum, and the virus is highly contagious, transmitted by direct contact with infected skin or contaminated objects, like towels, linens and toys. Scratching can cause autoinoculation which is when a person reinfects themself.
MC is very common, impacting an estimated 6 million adults and mostly children in the US each year. In 2010, there was an estimated 122 million cases worldwide. It occurs primarily in humid and warm climates, and transmission via swimming pools and bathtubs may be possible. Therefore, molluscum is often called “water warts.”
Many physicians may take a “watch and wait” approach since the virus may clear on its own. However, it can take months to up to 5 years for some to experience complete clearance, In the meantime, the person is still highly contagious and may spread the virus to others, particularly children. Lesions can be bothersome, causing itching and sometimes a secondary infection. There is also a psychosocial component. In a recent study, 1 in 10 children with molluscum experienced a major quality of life issue.
Berdazimer Gel, 10.3% is a potential first-in-class topical controlled-nitric oxide releasing medication containing Berdazimer (sodium), a new chemical entity, and the active ingredient in berdazimer gel 10.3%. The mechanism of action of berdazimer in the treatment of molluscum is unknown, but in vitro lab studies show that the nitric oxide, released when berdazimer is combined with a hydrogel, may impede viral replication and perhaps help body’s natural immune response against molluscum.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Over the last decade we have seen two trends occurring to rural hospitals – closures and mergers. A hospital in financial distress could likely face closure. But if the hospital affiliates with a multihospital system, it may have access to resources from the system that help shelter the hospital from closure.
That is exactly what we found in this study. System affiliation was associated with a lower risk of closure for financially distressed hospitals. However, among hospitals that were financially stable, system affiliation was associated with a higher risk of closure. This is somewhat puzzling and needs further study to better understand the reason for closure.
How long you can maintain a health regime is one of the biggest factors in its potential for success. ...

Response: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in children in the U.S., Europe and other world regions, currently affecting 1 in every 10 children, and 1 in every 3 children with obesity in the U.S. The rate of pediatric NAFLD has more than doubled in recent decades following the epidemic rates also noted for childhood obesity. There is increasing interest in the role that environmental chemical exposures may play in NAFLD etiology, since several animal studies have shown that prenatal exposures to endocrine-disrupting chemicals (EDCs) cause liver injury and damage; but, until now, the potential effects of prenatal EDC mixture exposures in pediatric NAFLD had not been studied.

MedicalResearch.com: What is the background for this study?
Response: Health care providers utilize subscription-based, point-of-care databases such as DynaMed and UpToDate to provide clinical care guidance and remain current on the latest evidence-based findings. Both of these websites maintain this content through a cadre of physician contributors who write and edit articles for these sites. These physician contributors are required to self-report any conflicts of interest (COI) as outlined by the respective policies on each website. However, prior COI research into similarly self-regulated areas, such as medical and pharmacology textbooks, and clinical practice guidelines, has found both appreciable potential COI and inconsistencies between self-reported and industry mandated disclosures (1-3).
This study (4) explored the accuracy of physician contributors to DynaMed and UpToDate by comparing their self-reported disclosure status with the financial remunerations they received from the healthcare industry (e.g., pharmaceutical companies) as reported to the U.S. Centers for Medicare and Medicaid Services’ Open Payments database. Physician contributors who reported “nothing to disclose” on their respective article topic but had an entry on Open Payments for having received money from industry, were classified as discordant and, thus, as having the potential for a COI. Additionally, total remuneration, gender, and payment category were investigated more in depth for each database.

Response: Peanut allergy is one of the most common childhood food allergies, and children rarely grow out of it. The only proven way to prevent peanut allergy is to give infants age-appropriate peanut products in the first year of life.
We previously showed there was a dramatic increase in peanut introduction from 2007-11 to 2018-19, following changes to infant feeding guidelines. We wanted to know if earlier peanut introduction would reduce peanut allergy in the general population (in Melbourne, Australia).
