Response: Skin cancer is the most common type of cancer in the United States, but it often does not cause serious complications or death. The Task Force’s recommendation on screening for skin cancer focuses on the effectiveness of visual skin exams for children and adults who do not have any symptoms. When reviewing the latest research, we found that there is currently not enough evidence to tell us whether or not screening people without signs or symptoms is beneficial. This is an I statement.

Response: Dog walking is an increasingly popular mode of physical activity for adults in the US, but its injury burden and associated risk factors are not fully understood. This study found that the 3 most common injuries sustained by adult dog walkers in the US were finger fracture, TBI, and shoulder sprain or strain. Dog walking-related injuries sent approximately 423,000 adults to US EDs between 2001 and 2020, with an annual average of more than 21,000 visits. During that 20-year period, the estimated annual injury incidence increased by more than 4-fold. Among injured dog walkers, older adults and women were particularly vulnerable to serious injury, such as fracture and TBI.

Response: Breast cancer is a significant public health problem, being the most commonly diagnosed cancer and the second leading cause of cancer death in women in the US. Breast cancer screening from age 50 has been associated with a reduction in mortality and is recommended by the US Preventive Services Task Force. However, there is a significant disparity in mortality rates between Black and White individuals, with Black women having a higher death rate, especially before age 50. The current one-size-fits-all policy for breast cancer screening may not be equitable or optimal, and risk-adapted starting ages of screening based on known risk factors, such as race and ethnicity, may be recommended to optimize the benefit of screening. Our study aimed to provide evidence for a risk-adapted starting age of screening by race and ethnicity.

Response: Clinical guidelines currently state that the atypical antipsychotic clozapine effectively treats patients with treatment-resistant schizophrenia (TRS) 1. TRS occurs in up to one-third of patients with schizophrenia.2,3 However, there is evidence that demonstrates a lack of clozapine utilization by providers.2 This underutilization has been attributed to clozapine’s numerous adverse effects, in particular agranulocytosis.4 Other barriers include close monitoring for agranulocytosis, changes in administration and registry programs, as well as concerns regarding physician’s attitude toward and knowledge about clozapine.4,5 These barriers have thus caused a sizable variation in clozapine usage throughout the US. Using Medicaid data from 2015-2019, we conducted a secondary data analysis to examine the varied usage of clozapine in the US Medicaid programs.6

MedicalResearch.com: What are the most common STIs prevalent in the US and worldwide today?
Response: By far, the most common STIs in the US and worldwide is Human Papillomavirus (HPV) that can cause cervical cancer in women and Herpes Simplex Virus (HSV) that is the cause of genital herpes. Outside of these two major causes of STI, the others that are very common are Chlamydia, Gonorrhea, Trichomoniasis and Syphilis. It is important to note that the reported cases represent only a subset of the individuals with an infection as many may be asymptomatic and could be spreading these STIs to others. HIV is another STI that is common but usually rests in its own category due to its impact.

Response: Prior studies have demonstrated that frequent (i.e., daily or near daily) use of aspirin is associated with a lower risk of developing ovarian cancer. We sought to determine if this risk reduction is also observed for individuals with greater genetic susceptibility to ovarian cancer, who may benefit more from preventive interventions.
Our study found that individuals who took aspirin frequently had a lower risk of ovarian cancer, regardless of whether they had higher or lower genetic susceptibility to ovarian cancer.
Response: We were broadly interested in discovering instances of bacterial genes that have been acquired by diverse animal genomes over millions of years of evolution by the process of horizontal gene transfer (HGT). Since these events are quite rare and most previous discoveries have been serendipitous, we developed computational methods to identify genes acquired by HGT in animals. One of the exciting discoveries from our work was that vertebrate IRBP appeared to have originated in bacteria and is now a critical component of the vertebrate visual cycle, so this paper focuses on that one discovery.
IRBP or interphotoreceptor retinoid binding protein is an important protein present in the space between two major cell types in our eyes, photoreceptor cells and RPE cells. Our ability to see involves an intricate set of steps where light is first sensed by causing a change (isomerization) in the chemical structure of molecules in the eye called retinoids. This sensing of light occurs in our photoreceptor cells. Following this change in the chemical structure, the retinoid needs to be recycled back to the chemical structure that can again sense light. This recycling occurs in RPE cells. IRBP performs the essential function of shuttling retinoids between the photoreceptors and the RPE cells, which allows the cycle of sensing and regeneration to work. Supporting its importance, mutations in IRBP (also known as retinol binding protein 3 or RBP3) can cause several severe human eye diseases.

Response: Words direct the attention of infants, children and adults to mentioned objects in the environment. When someone says “Can you find the candy,” you look to the candy sitting on the counter. This fact is the basis of many tests of infant cognition in laboratories. To find out if a child knows the word “bike” we put a picture of a bike and a truck on a TV screen, say the word “bike” and see if they look at the correct object.
There is also evidence that words can direct attention even if you don’t know what they mean yet. For example, in studies of learning in the lab novel made up words like “modi” can direct children’s attention to specific features of objects. One particular example of this is the “shape bias”. If a two-year-old is shown a novel object and told a novel name, for example “This is my blicket,” and then asked, “Can you get your blicket” and shown one object that matches the named one in shape and another that is made from the same material, they will attend to the one that matches in shape. Researchers think the naming event “This is my…” cues children to look at things that are the same shape because they already know many names for things in sets that are similar in shape; cups are all cup-shaped, keys are all key-shaped, spoons are all spoon-shaped, etc.
Prior research suggests there may be differences in the way children who struggle with language decide what a new word means. For example, children with Developmental Language Disorder do not pay attention to the same things when learning new words as children with typical language development. These children do not look to an object that matches a named exemplar in shape when asked to “get your blicket”. But you can’t diagnose children with DLD until they are 3 or 4. We want to see if we can identify these children earlier, so they can get early support.

Response: Prescription stimulant therapy for ADHD helps millions of people, including in my own family, and students, friends and colleagues. It's critical to balance the need for access to these medications while reducing the risk for misuse. This is more important than ever now because there have been recent increases in the prescribing of stimulant therapy for ADHD. There is a need to understand the prevalence of stimulant therapy for ADHD and prescription stimulant misuse in U.S. middle and high schools.

Response: The United States’ opioid epidemic continues to rise because of increasing opioid use and availability, contributing to prescription opioid misuse, mortality, and rising cost.1 The worsening health and economic impact of opioid use disorder in the US warrants further attention on the adverse effects and distribution pattern of commonly prescribed opioids like oxycodone (OxyContin), fentanyl (Duragesic), and morphine (MS-Contin). Using the Automated Reports and Consolidated Ordering System (ARCOS) database,2 a comprehensive data collection system of pharmacies and hospitals distribution of Schedule II and III controlled substances in the US with the FDA Adverse Event Reporting System (FAERS)3 has never been done before. This approach may provide a more complete picture of the risks of prescription opioids which can include drowsiness, nausea, and potentially fatal respiratory depression.

Response: High blood pressure, hypertension, is a growing global health challenge. Over the last 30 years, the number of people with hypertension has doubled, and it is estimated that around a third of adults aged 30-79 have the condition - a total of 1.28 billion people worldwide. Untreated hypertension can lead to kidney disease, heart disease, and stroke, accounting for 11.3 million deaths in 2021 alone. A small minority get their blood pressure under control with drug therapy, and some studies indicate that as little as half are taking their blood pressure medications as intended. Is this because the drugs' effectiveness and side effects differ between different individuals? If so, there would be a substantial risk that patients will not get their optimal medication on the first try, with poor blood pressure lowering and unnecessary side effects as a result.
In a new clinical trial in Sweden, it was studied whether there is an optimal blood pressure medication for each person, and thus a potential for personalized blood pressure treatment. In the study, 280 people with high blood pressure tried out four different blood pressure drugs on several different occasions over a total of one year.

Response: Prostate cancer is a common malignancy in men. Prostate cancer diagnosis is made largely through opportunistic screening with a PSA (Prostate Specific Antigen) blood test, followed by prostate biopsies. The ProtecT study, funded by the National Institute for Health and Care Research in the UK, is the largest randomised trial of treatment in screen-detected localised prostate cancer. The study began by testing 82,429 men between the ages of 50 and 69 years, across nine UK centres with a PSA blood test, followed by biopsies of the prostate if the PSA level was elevated. 2,664 men with clinically localised prostate cancer were found. From these, 1,643 (62%) agreed to be randomised to Surgery (radical prostatectomy to remove the prostate gland), Radiotherapy (external beam with a period of hormone treatment beforehand), or Active Monitoring (where men received regular checks and further investigations, with change to radical treatment as necessary). The men were carefully followed up for an average of 15 years. In parallel, the side-effects of treatments and quality of life of these men was investigated using patient-reported outcomes included in an annual study questionnaire completed for at least 12 years.

Response: While a fair amount of studies have focused on the effects of menopause and hormone therapy on risk of dementia, far fewer studies have tested their association with the biology of Alzheimer’s disease, namely amyloid and tau. This is critical to know given that it still remains unclear what might be the driving mechanism of the menopause transition on risk for dementia. This is what our study set out to investigate.
This study is one of the first to report a link between women’s age at menopause and tau in the brain, which we measured with positron emission tomography neuroimaging. We found that in multiple areas of the brain that tend to be most likely to show higher tau in women than men, women with earlier age at menopause and elevated levels of amyloid showed higher levels of tau than those who reported an average age at menopause (~50 years in the United States). Women who reported premature menopause (<40 years at menopause onset) exhibited a much higher risk of tau in the brain. This supports the notion that longer exposure to estrogen throughout life might be protective against Alzheimer’s disease.

MedicalResearch.com: What is the background for this study? Would you briefly describe the condition of Spinal muscular atrophy (SMA)?
Response: At the 2023 Muscular Dystrophy Association Conference, we presented new data from two of our Long-Term Follow-Up (LTFU) studies, LT001 and LT002, which show the continued efficacy and durability of Zolgensma across a range of patient populations, with an overall benefit-risk profile that remains favorable. LT001 is a 15-year ongoing observational LTFU study following the Phase 1 START patients, who were the very first patients to receive our gene replacement therapy. LT-002 is a voluntary Phase 4 15-year ongoing follow-up safety and efficacy study of Zolgensma IV and investigational intrathecal (IT) OAV101 in patients previously treated in the Phase 3 IV studies (STR1VE-US, STR1VE-EU, STR1VE-AP, SPR1NT) and the Phase 1 IT study (STRONG).
Spinal muscular atrophy (SMA) is a rare, devastating genetic disease that leads to progressive muscle weakness, paralysis, and when left untreated in one of its most severe forms (SMA Type 1), permanent ventilation or death in 90% of cases by age 2. It is caused by a lack of a functional survival motor neuron 1 (SMN1) gene, and in the most severe forms results in the rapid and irreversible loss of motor neurons, affecting muscle functions, including breathing, swallowing and basic movement.

Response: It is well known that someone with one substance use disorder will have another sometime in their lifetime or concurrently. Further, individuals that do manifest two or more substance use disorders in their lifetime have the most morbid conditions. However, research often ignores the comorbidity and focuses on diagnosis of one substance use disorder at a time (i.e. opioid use disorder or alcohol use disorder). We set out to identify the biology behind the cross-substance liability.

MedicalResearch.com: What is the background for this study?
Response: Rheumatoid arthritis, or RA, is a chronic disease, with joint inflammation as the primary manifestation. Due to advances in RA therapy and care, an increasing number of patients achieve sustained remission without joint damage progression and functional loss. For these patients, dose-reduction of disease modifying anti-rheumatic drugs (DMARDs), or complete withdrawal of therapy could be favorable due to potential reductions in adverse events, burden of taking medication, and healthcare costs. Current treatment recommendations suggest that tapering of conventional synthetic DMARDs could be considered in patients in sustained remission, but there is a lack of data to guide treatment decisions.
