Heavy drinking may raise cardiovascular risk by aging the arteries
Cardiovascular disease (CVD) is the leading cause of death worldwide, with over a third of global deaths being attributed to a cardiovascular event. In the United States, CVD accounts for 1 in every 4 deaths, killing around 610,000 people every year. More than half of these deaths occur in men, according to the Centers for Disease Control and Prevention (CDC). Some studies have shown that drinking alcohol in moderation may have a positive effect on cardiovascular health. However, these studies have been observational, and the exact causative mechanisms behind this association are unknown. Furthermore, the impact of drinking levels over time has not been fully understood.
Snow shoveling may increase risk of heart attack in men
New research finds associations between heavy, long-lasting snowfall and an increased risk of myocardial infection in men. Snow shoveling may be the cause. As winter draws to a close, those of us living in snowy areas might be relieved that we no longer have to shovel our way out of the house every morning - and for good reason. New research suggests that snow shoveling can increase the risk of heart attack. New research suggests that shoveling snow increases the risk of myocardial infection among men. Snow shoveling is a particularly strenuous activity, and our cardiovascular system "knows" it, too. The intense aerobic activity may be good exercise, but lifting too much heavy snow puts a disproportionate amount of strain on our arms compared with our legs, therefore increasing our heart rate, blood pressure, and oxygen demand. Together with the inhalation of cold air, this can lead to adverse cardiovascular events, also known as the "snow-shoveler's infarction." A new study, published in the Canadian Medical Association Journal, examines the link between large snowfalls, long periods of snow, and the risk of myocardial infarction (MI). Researchers led by Dr. Nathalie Auger, of the University of Montreal Hospital Research Centre in Montréal, Quebec, examined data from two databases, gathering a total of 128,073 patient admissions and 68,155 MI-induced deaths that occurred in Quebec between 1981 and 2014.
Male contraceptive proves effective as alternative to vasectomy
A new trial in adult rhesus monkeys tests the effectiveness of Vasalgel - a non-hormonal gel developed as a long-term form of male contraception. From birth control pills to non-hormonal injections, researchers have recently been investigating more and more options for male contraception. New research tests a contraceptive gel in monkeys as an alternative to vasectomy. A new trial shows promise for a non-hormonal gel as an alternative to vasectomy. Almost half of all pregnancies are unintended, according to the latest statistics from the Centers for Disease Control and Prevention (CDC). While women have traditionally had a wide range of contraceptives available to them, the medical research community has only recently taken an interest in developing male contraceptives. In 2016, the male non-hormonal contraceptive gel Vasalgel was successfully tested in rabbits, showing promise as a long-term contraceptive for males. Vasalgel is a high molecular weight polymer that could work as a potentially reversible alternative to vasectomies. In the new trial, researchers - led by Dr. Catherine VandeVoort, from the California National Primate Research Centre (CNPRC) - tested the drug in primates. The findings were published in the journal Basic and Clinical Andrology.
New pharmacon allows testicular tumors to shrink
A new active pharmaceutical ingredient may help against severe forms of testicular cancer, which only respond inadequately to other therapies. In mice, the substance kills degenerated cells and allows testicular tumors to shrink. Researchers at the University of Bonn were able to demonstrate this in a recent study. However, first clinical trials are still pending. The work has now been published in the Journal of Cellular and Molecular Medicine. Testicular cancer is the most common malignant tumor disease in men between 20 and 40 years of age. It can usually be treated well. In some cases, however, the cancer hardly responds or does not respond at all to treatment. A substance that was originally destined to be an innovative contraceptive is offering new hope in these cases. An experimental drug with the cryptic name JQ1 blocks sperm maturation and was discussed to be a male contraceptive. Instead, it may be suitable for cancer therapy. JQ1 belongs to a new class of drugs with far-reaching abilities: its members fundamentally influence which genes in the cell are active and which are not. The hereditary material DNA is similar to an extremely long strip of Morse code, on which the assembly instructions for the cellular molecules are found. To fit into the cell nuclei, this strip of Morse code is wrapped around small protein balls at regular intervals - the histones. Histones and DNA together resemble a string of pearls.
Benign Prostatic Hyperplasia: Treatment, Symptoms, and Causes
Benign prostatic hyperplasia refers to a condition in which the prostate enlarges. It can happen to a man as he ages, for reasons not entirely understood. The enlarged prostate may block or slow urine from the urethra. Benign prostatic hyperplasia (BPH) is different from prostate cancer. Having BPH does not increase the risk of developing prostate cancer.
Novel penile implant offers hope for men with erectile dysfunction
Athough implants and medication are available for individuals who have lost erectile function, there is currently no one-size-fits-all treatment. However, using an innovative heat-activated memory metal, researchers recently tested a new device and the results are promising.Although technology related to the penis can draw childish sniggers, it is a serious business. For instance, losing one's erectile function through cancer or injury can be a life-altering event. Erectile dysfunction is not uncommon; an estimated 40 percentof men aged 40-70 have some level of erectile dysfunction. Of these 40 percent, an estimated one-third do not respond to drugs such as Viagra. Brian Le, from the Department of Urology at the University of Wisconsin-Madison, recently investigated new technology that may, eventually, provide a reliable alternative. Le joined forces with Alberto Colombo and Kevin McKenna at Northwestern University, IL, and Kevin McVary at Southern Illinois University. Le says that: "It's a survivorship issue - restoring function can help people feel whole in their bodies again."
A stem cell strategy for boosting testosterone levels tested in rodents
Male hypogonadism is a condition that diminishes testosterone levels in approximately 30% of older men, but currently available therapies can produce serious side effects. In a study published December 22 in Stem Cell Reports, researchers developed an alternative approach involving the direct conversion of adult skin cells into functional testosterone-producing cells. When transplanted into male rodents with hypogonadism, these so-called Leydig-like cells survived and restored normal testosterone levels. "Our study is the first to report a method for generating Leydig cells by means of direct cell reprogramming," says senior study co-author Yadong Huang of Jinan University. "This alternative source of Leydig cells will be of great significance for basic research and provides the attractive prospect of clinical application in the field of regenerative medicine." Male hypogonadism is characterized by symptoms such as mood disturbances, sexual dysfunction, decreased muscle mass and strength, and decreased bone mineral density. One primary cause is the dysfunction of testosterone-producing Leydig cells in the testes. Testosterone replacement therapy can alleviate some symptoms resulting from Leydig cell failure, but it may also increase the risk of prostate and cardiovascular complications, such as the formation of blood clots.
Light therapy 'a huge leap forward' for early prostate cancer treatment
In a new study, a novel light therapy called VTP led to complete remission in almost half of men with early localized prostate cancer. In a study of more than 400 men with localized prostate cancer, researchers reveal that the new treatment - called vascular-targeted photodynamic therapy (VTP) - can kill prostate cancer cells, without damaging the healthy surrounding tissue. Furthermore, VTP was found to significantly reduce the need for radical therapy, such as the removal or irradiation of the entire prostate. Lead investigator Prof. Mark Emberton, dean of medical sciences and a consultant urologist at University College London in the United Kingdom, and colleagues recently reported their findings in The Lancet Oncology. After skin cancer, prostate cancer is the most common cancer in men in the United States, with around 180,890 new casesexpected to have been diagnosed in 2016. For men with localized prostate cancer - cancer that is considered low risk and has not spread beyond the prostate - "active surveillance" is often the first port of call. This is where the cancer is closely monitored through prostate-specific antigen (PSA) tests, digital rectal exams, or prostate biopsies, and it is only treated if it becomes more severe.
Exercise and infertility: What regimen is best for sperm quality?
Exercise intensity and semen quality have a complex relationship. Too much exercise can be bad and too little can be worse. New research finds the balance. Research, published this week in the journal Reproduction, investigates the effects of various exercise regimens on overall sperm quality. The results show that just a few months of activity can make a significant difference. Exercise and its effect on sperm quality is investigated in a new study. An estimated 1 in 3 couples find conceiving difficult because of poor semen quality. Often, these couples only have in vitro fertilization (IVF) as a treatment option; however, poor sperm quality is known to increase the risk of miscarriage, birth defects, and childhood cancer. Because of this, ways to naturally increase sperm quality are important for the health and well-being of current and future generations. Advice given to men to improve sperm quality includes eating well, reducing alcohol intake, quitting smoking, and exercising regularly. Although this is the standard mantra, evidence for the impact of exercise on sperm quality has, to date, been contradictory.
Computer modeling could lead to new method for detecting, managing prostate cancer
New research coauthored by Brigham Young University researchers may lead to a more accurate system for early detection, diagnosis, and treatment of prostate cancer. The new study, published in Proceedings of the National Academy of Sciences, details a computer model that uses medical images to reproduce the growth patterns of prostate cancer on the anatomy of a patient's prostate. This type of mathematical modeling and simulation of disease is called predictive medicine, a new trend in medical research that leads to personalized treatment and more accurate forecasting of clinical outcomes. "There is a lot of room for improvement in both the diagnosis and management of prostate cancer," said study coauthor Michael Scott, BYU professor of civil and environmental engineering. "We're using computer modeling to capture the behavior of prostate tumor growth which will hopefully lead to minimally invasive predictive procedures which can be used in clinical practice." Current diagnosis methods include invasive biopsy procedures which too often lead to patients being over-treated or under-treated. Complicating matters is the fact that prostate cancer can remain undiagnosed because early stages of the disease may not produce symptoms until a tumor is either very large or has invaded other tissues.
Prostate Exam: How is it Done and Who Should Have One?
What is the prostate gland and what is the prostate exam? Learn about the different tests commonly used to examine the prostate and why they are used. According to the American Cancer Society,1 in 7 menwill have a diagnosis ofprostate cancerin their lifetime. While researchers continue to work out whether or not prostate cancer can be prevented, prostate exams are performed to reduce the high numbers of deaths from the disease. There are two main tests commonly used to screen for prostate cancer. These are the digital rectal exam (DRE) and the prostate-specific antigen test (PSA).What is the prostate exam?Screening means looking for early signs of a disease in healthy people who do not have any symptoms. The aim of screening is to diagnose disease at an early stage as it is easier to treat and more likely to be cured.Who should get a test done?
Aerobic exercise boosts testosterone for overweight men
Researchers reveal how a 12-week aerobic exercise program significantly increased testosterone levels for men who were overweight or obese. As men age, testosterone levels decrease. This can cause a number of physical and emotional changes, including weight gain, loss of bone density, depression, and reduced sex drive. A new study, however, suggests that for men who are overweight or obese, a 12-week aerobic exercise program can significantly boost testosterone levels. Lead researcher Hiroshi Kumagai, of Tsukuba University in Japan, and colleagues recently presented their findings at the American Physiological Society's Integrative Biology of Exercise VII Meeting in Phoenix, AZ. Testosterone is a predominantly male sex hormone, mainly produced by the testicles. In men, testosterone is responsible for sustaining sperm production, sex drive, facial and body hair, muscle size and strength, fat distribution, red blood cell production, and bone density. According to the Mayo Clinic, men's testosterone levels typically start to decrease from the age of 30 or 40, falling around 1 percent each year.
Male birth control shot shows promise
Birth control injections for men have been shown to prevent pregnancy in their female partners and are effective in nearly 96 percent of continuing users. When it comes to birth control methods, women have more options than ever before. However, for men, the choice is limited to condoms, withdrawal, and vasectomy. A new study - published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism - has established that a male birth control shot is effective at preventing pregnancy. In the last 40 years, studies have demonstrated that reversible hormonal suppression of spermatogenesis - the process of sperm cell development - in men can prevent pregnancies in their female partners, although the commercial development of the product has been stalled. In previous studies, testosterone management in men demonstrated birth control efficacy comparable with female methods. However, participants had to be given much greater doses than are typically found in the body and the method caused long-term adverse effects in healthy men.
