MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The background “UNICEF (2014) estimates that worldwide more than two hundred million women have undergone some form of FGM/C, and approximately 3.3 million girls are cut each year. Recent estimates show that if FGM/C practices continue at current, 68 million girls will be cut between 2015 and 2030 in 25 countries where FGM is routinely practiced and more recent data are available (UNJP, 2018).”
Main findings: The prevalence of FGM/C among children varied greatly between countries and regions and also within countries over the survey periods. We found evidence of significant decline in the prevalence of FGM/C in the last three decades among children aged 0–14 years in most of the countries and regions, particularly in East, North and West Africa. We show that the picture looks different in Western Asia, where the practice remains and affects the same age group.

Response: One of the cited repercussions of the opioid epidemic is its effect on families. However, there is considerable variation in opioid misuse across the county. This is the first nation-wide study to investigate the relationship between opioid prescription rates and child removals at the state level.
I found that there are significant differences across states in the relationship between opioid prescription and child removal rates associated with parental substance abuse. In twenty-three states, increases in opioid prescription rates were associated with increases in the child removal rate. For instance, in California a 10% increase in the county average prescription rate was associated with a 28% increase in the child removal rate. By contrast, in fifteen states the association was flipped, where increases in the opioid prescription rate were associated with decreases in the child removal rate. There was no statistically significant relationship in the remaining states.

Response: New blood pressure guidelines, issued in 2017 in the US, lowered the blood pressure thresholds for hypertension from systolic blood pressure/diastolic ≥140/90 mm Hg to systolic/diastolic ≥130/80 mm Hg. This change increased the prevalence of hypertension two- to three-fold among young adults. The guidelines also newly defined elevated blood pressure as, 120-129 mmHg systolic blood pressure over 80 mmHg diastolic or less. However, no study investigated that high blood pressure, as defined by the new criteria, is something that younger people should be concerned about as a potential precursor to serious problems.
Our study is among the first to report that people younger than age 40 who have elevated blood pressure or hypertension are at increased risk of heart failure, strokes and blood vessel blockages as they age.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The use of cannabis during pregnancy is a growing health concern, yet the long-term cognitive ramifications for developing offspring remain largely unknown. Human studies exploring the long-term effects of maternal cannabis use have been sparse for several reasons, including the length and cost of such studies, as well as the fact that experimentally assigning mothers to smoke cannabis during pregnancy is obviously ethically impractical. Animal models of maternal cannabis use have been advantageous in this respect, but they have been limited by the drugs used (synthetic cannabinoids vs. THC vs. cannabis plant) and the way that they are administered. In our study, we used a more translationally relevant animal model of maternal cannabis use that exposes pregnant rat dams to whole plant cannabis extracts using the intra-pulmonary route of administration that is most common to human users. Our preliminary data indicate that twice-daily exposure to a high-dose cannabis extract during pregnancy may produce deficits in cognitive flexibility in adult rat offspring. Importantly, these rats did not experience general learning deficits, as they performed comparably to non-exposed offspring when required to follow a cue in their environment that dictate reinforcer delivery. Instead, deficits were observed only when rats were required to disregard this previous cue-based strategy and adopt a new egocentric spatial strategy in order to continue receiving the sugar reinforcers.

MedicalResearch.com: What is the background for this study?
Response: Dapagliflozin, an SGLT2 inhibitor (sodium-glucose co-transporter 2), has been shown to improve glycemic control by decreasing glucose reabsorption in the kidneys and inducing urinary glucose clearance. SGLT2 inhibitors have also been shown to be effective in lowering albuminuria and stabilizing eGFR (estimated glomerular filtration rate). The effect of dapagliflozin on UACR (urine albumin-to-creatinine ratio) has been shown to vary among patients.
The objective of this post-hoc analysis, based on the pooled data from 11 randomized, placebo-controlled clinical trials, was to assess baseline characteristics and concurrent changes in cardiovascular (CV) risk markers associated with UACR response to dapagliflozin.

Response: Renin-angiotensin-aldosterone system inhibitors (RAASi) are guideline-recommended therapies for patients with chronic kidney disease (CKD), but are commonly prescribed at suboptimal doses, which has been associated with worsening clinical outcomes. The objective of our study was to estimate the real-world associations between RAASi dose and adverse clinical outcomes in patients prescribed RAASi therapies with new-onset CKD in the UK.

MedicalResearch.com: What is the background for this study?
Response: Infective endocarditis is an infection of the heart valves that has a high death rate (around 30% in the first year). It requires intensive treatment often involving replacement of affected heart valves and frequently results in serious long-term illness and disability in those who survive as well as an increased risk of re-infection and high healthcare costs.
In ~40% of cases, bacteria from the mouth are implicated as the causal organism. Because of this, guideline committees around the world recommended that all those at risk of infective endocarditis should receive antibiotic prophylaxis before undergoing invasive dental procedures. Due to a lack of evidence for efficacy, however, guideline committees started to limit the use of antibiotic prophylaxis. And in 2007, the American Heart Association (AHA) guideline committee recommended that antibiotic prophylaxis should continue for those at high-risk but should cease for those at moderate risk of endocarditis. Most guideline countries around the world followed suite. Except in the UK, where the National Institute for Health and Care Excellence (NICE) recommended that the use of antibiotic prophylaxis should completely stop in 2008.

Response: Our lab has an interest in the early events and initiation of neurodegenerative diseases. Parkinson’s disease for a long time was thought to be a movement disorder driven by the destruction of dopamine neurons in a specific area of the brain, the substantia nigra. In the last 10 years it has become evident that Parkinson’s disease is not just a movement disorder but hosts a whole range of non-motor systems. One of the most common non-motor symptoms in Parkinson’s patients is issues with the gastrointestinal (GI) tract. GI symptoms often occur early in Parkinson’s disease; for many patients, GI symptoms precede the onset of motor symptoms by as many as 2 decades. Moreover, the GI is not only involved in the early signs of Parkinson’s but has been proposed to be a place in the body where Parkinson’s disease begins.
The hallmark pathology of Parkinson’s disease in the brain is Lewy bodies, which contains a clumped form of a protein called alpha-synuclein. There is evidence that Parkinson’s disease pathology, this clumped alpha-synuclein protein, is detectable in the GI tract, even many years before the onset of Parkinson’s motor symptoms. Clumped alpha-synuclein is also capable of traveling across nerve cells. There is evidence that clumped alpha-synuclein can travel up the nerve that connects the GI tract to the brain and enter the brain. This could be disastrous because clumped alpha-synuclein can seed and spread in the brain, which has neurotoxic effects and can eventually lead to Parkinson’s disease. In fact, in the brain of Parkinson’s patients, one of the first places where alpha-synuclein clumps are detected is at the terminal where the gut nerve connects to the brain, and this pathology advances from this point to other brain areas as the disease progresses.
This intriguing connection of the GI tract to the early processes of Parkinson’s disease had us interested in trying to understand how the gut could be involved in triggering Parkinson’s. But the GI tract is a very big place, and we first asked ourselves, where should we look to better understand GI involvement in Parkinson’s disease?

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Rheumatoid Arthritis (RA) can diminish patients’ work productivity and increase the risk of long-term disability, economic insecurity and worsening health, but limited research informs these issues. The purpose of our study was to examine associations between patients’ RA disease activity and their productivity and workplace support, using real-world data from the ArthritisPower research registry.
Our study looked at a sample of participants with RA who had a history of or current treatment with non-biologic and/or biologic disease-modifying antirheumatic drugs (DMARD) (n=296). Among the study sample, 74 percent had high disease activity (HDA) as determined by RAPID3 (>12), a common measure of disease activity in RA.
