Semaglutide as a Game Changer for Weight Loss

Posted by | Feb 2022

Mark A. Moyad, MD, MPH, the Jenkins/Pokempner Director of Preventive/Complementary and Alternative Medicine (CAM) at the University of Michigan Medical Center in the Department of Urology in Ann Arbor, Michigan, and Martin M. Miner, MD, Co-Director of the Men’s Health Center and Chief of Family and Community Medicine for Miriam Hospital, and Clinical Professor of Family Medicine and Urology at the Warren Alpert Medical School of Brown University in Providence, Rhode Island, discuss the potential benefits of semaglutide, a newly approved weight-loss drug. Dr. Moyad begins by summarizing the damage done by past weight-loss drugs, noting that they inevitably came with a huge catch and were never heart-healthy. He then introduces semaglutide, a recently-approved drug which has been shown to result in 15% weight loss over 2 years. Dr. Miner elaborates, explaining that there have been 4 studies of semaglutide featuring over 4500 individuals and that it is extremely safe. He highlights that the smaller dose in diabetics has also been shown to improve renal and cardiovascular outcomes, and that these outcomes are now being studied in non-diabetics. Dr. Miner argues that these results suggest semaglutide is a game changer. Dr. Moyad then discusses potential catches, noting that while the side effect profile seems good, the cost is very high at nearly $900 per month, and it is not covered by most insurance. Dr. Miner suggests that the price will go down once some time has passed from the initial approval. He does highlight as a negative the fact that semaglutide is given once per week as a subcutaneous injection, and suggests that it will be beneficial if the oral version currently under investigation is found to be effective. Drs. Miner and Moyad also ponder the long term impacts of semaglutide and sustained weight loss on testosterone levels, blood pressure, and depression. Dr. Moyad concludes by discussing his curiosity about the potential impact of semaglutide in a urologic setting.

Testosterone, Weight Loss / Weight Gain, and Testosterone Replacement Therapy (TRT)

Posted by | Feb 2022

Mark A. Moyad, MD, MPH, the Jenkins/Pokempner Director of Preventive/Complementary and Alternative Medicine (CAM) at the University of Michigan Medical Center in the Department of Urology in Ann Arbor, Michigan, and Martin M. Miner, MD, Co-Director of the Men’s Health Center and Chief of Family and Community Medicine for Miriam Hospital, and Clinical Professor of Family Medicine and Urology at the Warren Alpert Medical School of Brown University in Providence, Rhode Island, investigate the ways in which body mass index (BMI) correlates with testosterone levels and how this knowledge can be used in a medical setting. Dr. Moyad begins the discussion with Dr. Miner’s presentation on the possibility of testosterone needs increasing as BMI increases, wherein Dr. Miner found that obese men required higher doses of testosterone to reach eugonadal levels than men who were not obese. Dr. Miner states that he expects the results of a long-term safety study of testosterone will soon show that testosterone therapy is safe over the long term, allowing physicians and researchers to focus on the symptomatic benefit of testosterone in areas such as mood and cardiovascular risk. Dr. Moyad asks if weight loss and increased fitness could possibly reduce the need for testosterone therapy, to which Dr. Miner responds that it may be possible if both weight loss and a reduction in comorbidities occur but it is unlikely in patients over 60. They conclude that weight loss can help make testosterone therapy more effective but it is unclear if it would be enough to reduce testosterone therapy altogether because of a multitude of genetic variables.

Saw Palmetto and BPH – Past, Present, and Future

Posted by | Feb 2022

After an introduction from E. David Crawford, MD, Professor of Urology at the University of California, San Diego, and Editor-in Chief of Grand Rounds in Urology, Mark A. Moyad, MD, MPH, the Jenkins/Pokempner Director of Preventive/Complementary and Alternative Medicine (CAM) at the University of Michigan Medical Center in the Department of Urology in Ann Arbor, Michigan, interviews J. Curtis Nickel, MD, FRCSC, the Canada Research Chair in Urologic Pain and Inflammation and Professor of Urology at Queen’s University in Kingston, Ontario, on the history of the herbal medicine saw palmetto and its efficacy as alternative medicine for benign prostatic hyperplasia (BPH). Dr. Moyad observes that in the early 2000s, saw palmetto was widely discussed in North America, but seems to have disappeared from the conversation in recent years. Dr. Nickel explains that while this is true, saw palmetto continues to be developed as a treatment option in Europe. He then notes that the STEP and CAMUS trials were some of the main contributors to North American loss of interest. The 2006 STEP trial failed to prove that saw palmetto had greater efficacy than placebo in BPH by North American medical standards, which Dr. Nickel believes was due to there being different forms and sources of saw palmetto extract and it being difficult to control for which would be used in a study at the time in North America. Dr. Moyad highlights that while this trial may not have found a benefit to saw palmetto, it also found it to be as safe as placebo. Dr. Nickel then goes into further detail about the CAMUS trial, which he worked on, and which was initially based heavily on European studies. However, due to the negative results of the STEP trial, CAMUS was redesigned, and ultimately it too found little difference between saw palmetto and placebo. Dr. Nickel notes that he feels that he and his fellow researchers may have missed something critical in that trial, and ponders why the two North American studies had negative results while so many other trials had positive ones. He also notes that he continues to recommend saw palmetto as an adjunct therapy to many of his patients based on the international literature. Drs. Moyad and Nickel then discuss some of the sourcing difficulties related to saw palmetto, as well as different extraction methods. Dr. Moyad then references Permixon, a European medicinal product derived from saw palmetto, and Dr. Nickel discusses how the way that it is regulated and processed differs from how saw palmetto is handled in North America. Dr. Nickel clarifies that he thinks that saw palmetto is a good alternative treatment for BPH patients looking for less invasive disease management options as long as a USP (US Pharmacopeial Convention)-approved product that is analyzed thoroughly is used.

Testosterone as a Fasting Blood Test?

Posted by | Jan 2022

Mark A. Moyad, MD, MPH, the Jenkins/Pokempner Director of Preventive/Complementary and Alternative Medicine (CAM) at the University of Michigan Medical Center in the Department of Urology in Ann Arbor, Michigan, and Martin M. Miner, MD, Co-Director of the Men’s Health Center and Chief of Family and Community Medicine for Miriam Hospital, and Clinical Professor of Family Medicine and Urology at the Warren Alpert Medical School of Brown University in Providence, Rhode Island, discuss recent guidance suggesting that a fasting blood test is needed for testosterone. Dr. Moyad begins by explaining that in 2018, the Endocrine Society Clinical Practice Guidelines included a recommendation of measuring fasting morning testosterone. He suggests that this is a logical recommendation since, in a subset of men, testosterone levels may be temporarily lowered by food intake, but notes that this guidance does not appear to be widely known or followed. Dr. Miner says that he actually does usually include testosterone with other morning fasting tests to meet the demands of insurance, although he argues that this may also result in inaccurate levels since testosterone is supposedly at its peak in the afternoon. He also mentions that the American Urological Association does not recommend getting testosterone tested in a fasting specimen, although he is unsure why this is. Dr. Moyad concludes that this is a topic that is just beginning to be explored and should be watched.

Diet Only and Prostate Cancer

Posted by | Aug 2021

Mark A. Moyad, MD, MPH, Jenkins/Pokempner Director of Preventive/Complementary and Alternative Medicine (CAM) in the University of Michigan Department of Urology, reviews several trials showing the impact of dieting to lose weight on cancer and cancer recurrence, focusing particularly on prostate cancer. He begins with a discussion of the WINS and WHEL trials on dietary changes and breast cancer which, together, found that improving the quality of a diet does not appear to have a profound impact on cancer or recurrence, but that while dieting with a focus on weight loss reduces recurrence rates and establishes a number needed to treat (NNT) of 38. Dr. Moyad continues with preliminary data from the Success-C trial, a study with the goal of using caloric reduction and exercise to reduce weight and is showing that those who adhere to the lifestyle changes have significantly improved rates of disease-free survival. He then looks at the POUNDS LOST trial, whose results suggest that, regardless of the weight-loss process, if weight loss occurs then health benefits can be reached. Dr. Moyad also discusses the CALERIE and MEAL trials. The former study had patients cut back calories by 13% on average and showed that slow methodical weight-loss creates heart-healthy metabolic and numeric changes. The latter had active surveillance participants significantly increase their vegetable intake but has not currently found any remarkable differences between the control and intervention groups. He also discusses the latest impressive vegan randomized study, which demonstrated dramatic weight loss of 14 lbs over 16 weeks utilizing a practically unrecognized caloric reduction strategy. He summarizes the results of over 85 studies on excess alcohol and adipose tissue which support the idea that both are carcinogens and are shown to reduce the efficacy of some drugs. Dr. Moyad also observes that data on lycopene shows that increased fruit and vegetable intake is supportive of overall heart health, how recent research shows no clear cause and effect link between cancer and vitamin D or omega 3s, and how the MANSMED trial shows the benefit of using metformin in addition to standard-of-care therapy. He concludes by observing that heart-healthy calorie restriction programs that encourage adherence, happiness, and healthy outcomes are good for managing prostate cancer, and by briefly discussing the potential of semaglutide injections to help some patients lose weight.
