Tooth discoloration is such a common issue. It can be caused by improper brushing habits, smoking, or even drinking too many dark beverages like coffee or tea. So, people often opt for teeth whitening as a resolution.
Teeth whitening isn’t the only solution for tooth discoloration. Dental veneers, which are little shells that get placed over the teeth, can cover up yellowed teeth or teeth with brown spots quite effortlessly. This way, you won’t have to worry about regularly getting your teeth bleached or purchasing expensive teeth-whitening products.

MedicalResearch.com: What is the background for this study?
Response: The brain is highly active during sleep, which makes it an important, natural way to study neurological health and disease. Scientists typically study brain activity during sleep using the electroencephalogram, or EEG, which measures brainwaves at the scalp. Starting in the mid 1930s, the sleep EEG was first studied by looking at the traces of brainwaves drawn on a paper tape by a machine. Many important features of sleep are still based on what people almost a century ago could most easily observe in the complex waveform traces. Even the latest machine learning and signal processing algorithms for detecting sleep waveforms are judged against their ability to recreate human observation.
In this study, the researchers asked: What can we learn if we expand our notion of sleep brainwaves beyond what was historically easy to identify by eye?
Compassion fatigue is when you are exposed to suffering, trauma, or similar negative emotional states in others so much that you become desensitized and indifferent to it. You may also hear it referred to as secondary trauma or vicarious trauma, with many arguing that it’s an inevitable response.
Whichever name you use, it’s a condition in which you feel physically and psychologically exhausted, resulting in a diminished capacity for empathy. This, in turn, has a negative impact on your ability to do your job as a nurse.
Sadly, compassion fatigue is not uncommon in the healthcare field, which is why it’s so important to be alert to the symptoms and understand how to respond when they arise.

Response: The background of this story is to see whether things outside of the cancer cell, such as the tumor microenvironment, can lead to epigenetic changes within the cancer cell. These changes are largely believed to be due to factors inside the cell, not outside.
Super-enhancers are the top 1-2% of enhancers in the genome. They control cell identity genes and oncogenes in cancer.

MedicalResearch.com: What is the background for this study? What is the chemical primarily used in hair straighteners?
Response: Hair products such as dye and chemical straighteners contain several different chemicals that may act as carcinogens or endocrine disruptors and thus may be important for cancer risk. Straighteners in particular have been found to include chemicals such as phthalates, parabens, cyclosiloxanes and metals and may release formaldehyde when heated. Previous research has suggested that hair dye and chemical straighteners are related to other hormone-sensitive cancers such as breast and ovarian cancer, but no previous study has considered how they are related to uterine cancer risk.

MedicalResearch.com: What is the background for this study?
Response: It is estimated that social factors like poverty, education, and housing have a large impact on health. Yet, there are few interventions that exist to directly address those issues. Schools are a promising solution since society already invests heavily in education and schools are an everyday part of most children’s lives.

Response: Concerns on the possibility of (direct oral anticoagulants) DOAC-related nephropathy may limit its use.
In this cohort study of non-valvular AF patients from routine clinical practice, initiation of DOAC vs (vitamin K antagonists) VKA was associated with more favorable kidney outcomes, i.e., a lower risk of the composite of kidney failure and sustained 30% eGFR decline, as well as a lower risk of AKI occurrence.
In agreement with trial evidence, we also showed that DOAC vs VKA treatment was associated with a lower risk of major bleeding, but a similar risk of the composite of stroke, systemic embolism or death.
One example of Dermatomyositis: DermNet image[/caption]
Response: Dermatomyositis is a rare autoimmune inflammatory disease that affects muscles and skin, although muscular forms without skin symptoms and vice versa are also seen. The exact etiology of the disease is not known but is thought to be immune-mediated with many patients having highly specific autoantibodies. There is no cure for dermatomyositis, but several types of treatment have been successfully used in the last years including different kinds of immunosuppressants (e.g. steroids) and intravenous immune globulins (IVIG) to improve the patient’s condition. So far, none of these treatments was approved for use in dermatomyositis based on large, randomized, placebo-controlled trials. Their effectiveness was mainly deduced from clinical experience and from small clinical trials. The ProDERM study was the first large, pivotal, randomized placebo-controlled trial to evaluate the efficacy and safety of intravenous immune globulin (IVIG) in dermatomyositis patients.

Response: Syphilis has become more common over the past 20 years, after reaching a record low in 2000. The Task Force found that screening people who are at increased risk for syphilis can identify the infection early so it can be treated before problems develop. For that reason, the Task Force recommends screening people who are at increased risk for syphilis infection.

MedicalResearch.com: What is the background for this study?
Response: Teens face myriad challenges to sleep, ranging from biological factors, including a preference for later bedtimes and increased need for sleep, to social factors, including social pressures and increased academic workloads, all limiting teenagers in their ability to keep a healthy sleep schedule.
In a nationally representative sample, we explored the prevalence of another potential barrier to sleep among teens, which are a set of beliefs that are held in the population, yet are actual counter to scientific principles regarding sleep and circadian rhythms.

MedicalResearch.com: What is the background for this study? Response: The COVID-19 pandemic placed tremendous financial pressure on hospitals. Beginning in March of 2020, hospitals cancelled outpatient and elective procedures to accommodate surges in demand from COVID-19 patients. As these procedures account for more than 60% of an average hospital’s revenue, cancellation posed serious challenges to the financial health of hospitals. Revenue from COVID-19 patients may have partially offset these effects, but the American Hospital Association estimated a total loss of $202.6 billion by American hospitals between March and June 2020. In response, the U.S. government created large federal assistance programs aimed to stabilize hospitals’ financial situation as their ability to maintain operations was critical to the health of the nation. Due to differences in hospital characteristics, certain hospitals such as rural hospitals and those serving a higher share of Medicaid and uninsured patients (e.g., safety net hospitals) may have been more financially susceptible to the effects of the pandemic. These hospitals that serve vulnerable patient populations historically have had lower profit margins and were candidates for targeted COVID relief funding (e.g., Safety Net Hospitals Payments, a $10 billion component of the Provider Relief Fund).

MedicalResearch.com: What is the background for this study?
Response: Type 2 diabetes is a condition where blood glucose (sugar) is elevated in the blood. This can be problematic as it leads to blood vessel damage and the promotion of cardiovascular disease. Nearly 30 million people in the U.S. have type 2 diabetes, making it a major public health issue. The cause is not entirely clear, but many, including our team view insulin resistance as a central culprit.
Insulin resistance is when the body does not respond well to the hormone insulin. Insulin is vital because it promotes glucose uptake into tissues, like skeletal muscle. Two reasons that are often used to explain the development of insulin resistance include: poor diet (e.g. high sugar and/or high fat coupled with excess calories) and a lack of physical activity. However, more recently, a lack of sleep has been raised as another critical behavioral factor contributing to insulin resistance. Thus, targeting a healthy diet, activity and sleep pattern is thought to prevent the transition from health to insulin resistance and type 2 diabetes.

Response: As the population is living longer, there is increased risk of frailty and vulnerability. Frailty is defined as reduced physiological reserve and decreased ability to cope with even an acute stress. Up to half of adults over the age of 85 are living with frailty and preventative measures are greatly needed. We tested the effect of vitamin D and marine omega-3 fatty acid supplementation on the risk of developing frailty in healthy older adults in the US enrolled in the VITamin D and OmegA-3 TriaL (VITAL) trial.

MedicalResearch.com: What is the background for this study?
Response: A potential infectious etiology has been hypothesized for neurodegenerative diseases, as findings in animal studies have demonstrated that infectious processes might impact pathogenesis, phenotype, and progression of neurodegenerative disease.
The extrapolation of such findings to a human context is however not straightforward. previous studies have mostly examined the role of specific pathogens on a specific neurodegenerative disease, e.g., herpesvirus for Alzheimer’s disease, and influenza, hepatitis C virus, and Helicobacter pylori for PD, with inconclusive results. Although several studies have also assessed associations between infectious diseases and risk of dementia and AD, influence of potential surveillance bias (greater-than-expected surveillance of disease after infections) and reverse causation (due to for example diagnostic delay of neurodegenerative diseases) on the associations was not always fully addressed.
Therefore, whether infection is indeed a risk factor rather a comorbidity or secondary event of neurodegenerative disease remains unknown. In contrast to Alzheimer’s disease, and Parkinson’s disease, the potential link between infection and ALS has been less explored.

MedicalResearch.com: What is the background for this study?
Response: Prediabetes and type 2 diabetes have historically been far more common in adults, but the number of children and teens who have these conditions is rising. However, there is still very limited research on whether screening, early detection, and early treatment of diabetes will improve a child’s long-term health. Due to this lack of evidence, the Task Force was unable to assess the benefits and harms of screening, particularly in Black, Hispanic, American Indian, and Pacific Islander populations, who are at a significantly higher risk of developing type 2 diabetes. We are calling for more research on this important topic.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects multiple organ systems. Rash and arthritis are among the most frequent manifestations of the disease and severe organ damage can also occur especially when organs like the kidney are affected. Litifilimab (known as BIIB059) is a monoclonal antibody being studied for the potential treatment of SLE and cutaneous lupus erythematosus (CLE).
The Phase 2 LILAC study evaluated litifilimab versus placebo in two parts: Part A in participants who have SLE with active joint and skin manifestations; and Part B in participants with active CLE, including chronic and subacute subtypes, with or without other organ involvement. Results from the SLE portion of the study (Part A) show litifilimab met the study’s primary endpoint by significantly reducing total active joint count compared to placebo. Total active joint count was defined as the total number of tender or swollen joints. Litifilimab was generally well tolerated, with most reported adverse events (AEs) rated as mild or moderate. Note, this Phase 2 trial was not powered to assess secondary endpoints.
Based on these positive Phase 2 results, Biogen is currently enrolling participants into the Phase 3 TOPAZ-1 and TOPAZ-2 studies, which will evaluate the efficacy and safety of litifilimab in participants with active SLE worldwide.
Part B results from LILAC were published separately in NEJM on July 28, 2022 and expand the body of evidence supporting litifilimab as a potential first-in-class therapy for cutaneous lupus erythematosus in addition to SLE.

Response: Dementia and other cognitive impairment are highly prevalent among older adults in the U.S. and globally, and have been linked to deficiencies in decision-making, especially financial decision-making. However, little is known about the extent to which older adults with cognitive impairment manage their own finances and the characteristics of the assets they manage.
The rising incidence of early-onset cancers is likely at least partly attributable to enhanced screening and early detection. However, there...

Response: Private equity (PE) acquisitions of physician practices are accelerating across many specialties, but there is still little robust evidence on the effects of these acquisitions. Concerns about PE involvement is predicated on the fact that these firms expect high annual returns, which require either reducing costs or increasing revenue, or both. Using PE acquisition data from 2016-2020, linked to commercial claims data, we sought to understand what common mechanisms of revenue generation were being adopted after private equity acquisition of physician practices.
