Epidemiological data indicate an explosion of type 2 diabetes cases for women after menopause. What is responsible for that? The surprisingly protective role of oestrogens, highlighted by the fact that a woman undergoing hormone replacement therapy has up to 35% less risks of developing type 2 diabetes than a woman without treatment. By elucidating how oestrogen affects two of the hormones involved in glucose homeostasis, glucagon and GLP1, researchers at the University of Geneva (UNIGE), Switzerland, and at the Geneva University Hospitals (HUG) prove the value of oestrogen supplementation from the onset of menopause.
New research does not support the previously observed negative impacts of antidepressant use on breastfeeding. In the British Journal of Clinical Pharmacology study, use of serotonin reuptake inhibitors in late pregnancy was not linked with an increased risk of women experiencing low milk supply.
Electrodes for longterm monitoring of electrical impulses of heart or muscles in the form of temporary tattoos produced using an ink-jet printer. An international research group involving TU Graz, Austria, presents this novel method in Advanced Science.
Early adulthood is particularly critical for putting on weight. According to a recent study conducted at the University of Helsinki, common factors among young women and men who succeeded in managing their weight in the long term included eating regularly rather than dieting.
Maternal obesity and androgen excess induce sex-specific anxiety in the offspring, according to a study on mice by researchers at Karolinska Institutet in Sweden published in The FASEB Journal. The findings may help explain why children born to mothers with polycystic ovary syndrome (PCOS) have increased risk of developing anxiety later in life.
Use of nonsteroidal anti-inflammatory drugs (NSAIDs) was associated with an 18% increased risk of atrial fibrillation—an irregular, often rapid heart rate—in a study of middle-aged adults in Taiwan. The findings are published in the British Journal of Clinical Pharmacology.
In a new Respirology study, having measles—a highly contagious respiratory infection—during early childhood was linked with an increased risk of developing chronic obstructive pulmonary disease in middle age, but only in adults with asthma and a considerable history of smoking.
Prolonged sitting time and low physical activity levels were linked with the development of lower urinary tract symptoms (LUTS) in a BJU International study of 69,795 middle-aged Korean men.
An analysis of 3 US cancer databases has shown that a major US study comparing surgery with observation in early prostate cancer patients, the PIVOT study, used patients which didn’t properly reflect the average US patient. Researchers found that patients in the PIVOT trial were between 3 and 8 times more likely to die than real-world patients. This may call into question the conclusions of the study, which are now being implemented in the US and worldwide. It was presented at the European Association of Urology congress (EAU18) in Copenhagen on 17 March, following publication as a letter in the peer-reviewed journal, European Urology.
The PIVOT study was a near 20-year study of 731 men with low-, intermediate-, and high-risk prostate cancer. The study was reported in a paper in the NEJM in 20173, with the most important finding being that there was almost no difference in the overall mortality between patients undergoing surgery and those who opted for observation (although those treated reported more side-effects).
Presenting in Copenhagen, Dr Firas Abdollah (Detroit) said “The direct clinical implication of the PIVOT study is that we should abandon surgery in virtually all prostate cancer patients, and limit our management to observation. However, in most experts’ opinion, this would result in a significant increase in the number of men with metastatic prostate cancer, and in those who will succumb to the disease.”
The PIVOT study took data from patients from men with localized prostate cancer (median PSA value, 7.8 ng per millilitre) who were then randomized to radical prostatectomy or observation at Department of Veterans Affairs and National Cancer Institute medical centre.
A new appraisal of the PIVOT study carried out by scientists at the Henry Ford Hospital, Detroit, compared the characteristics of the patients used in the PIVOT study with 3 large US databases, to see if the PIVOT database really reflected ‘real-world’ prostate cancer patients. They compared PIVOT with:
60,089 men from the Surveillance, Epidemiology, and End Results (SEER; population-based registry) between 2000-2004
63,303 men from the National Cancer Database (NCDB; hospital-based registry) from 2004-2005
2,847 men diagnosed with prostate cancer in the PLCO trial between 1993 and 2001
They found that
The men in the PIVOT study were older and sicker than would be found in a normal population, which might have biased the results of the trial. Indeed, overall mortality in the PIVOT study was 64% over 12.7 years, whereas in the other databases it was between 8 and 23% over a similar timescale (7.5-12.3 years).
In addition, the men in the PIVOT trial had a mean age of 67 at diagnosis, compared with 65.8 (PLCO), 61.3 (SEER) and 60.2 (NCDB).
Lead author Dr Firas Abdollah said:
“Our work shows that the PIVOT trial used a sample of patients who were not representative of the real population affected by prostate cancer. They were both older and sicker than we would have expected. We don’t have the data to say what comparing like for like would give us, although I think everyone would be surprised if it didn’t tip the survival data more towards surgical intervention. What this really means is that we need to wait until a definitive study can show the relative benefits of intervention versus observation.”
Commenting, Professor Hein Van Poppel (Leuven, Belgium), EAU Adjunct Secretary-general said:
“It was clear from the first PIVOT analysis in 2012, that surgery (radical prostatectomy) had an advantage over waiting in patients with a poor prognosis. Now this evaluation of the dataset used in PIVOT suggests that the balance needs to change even in early-stage prostate cancer patients. This raises significant questions over just how relevant PIVOT is to real prostate cancer patients, and we need to seriously re-evaluate the PIVOT study, before taking implementation any further.”

Lower temperatures can activate the body’s ‘good’ fat formation at a cellular level, a new study led by academics at The University of Nottingham has found.
The research, published in the journal Scientific Reports, shows for the first time that the way in which fat is made within the body is not ‘pre-programmed’ during the early years of development as previously thought but even in adulthood cells can be influenced by our environment to change the type of fat that is formed.
Worldwide, overuse of inappropriate tests and treatments such as imaging, opioids and surgery means patients are not receiving the right care, and resources are wasted
Low back pain is the leading cause of disability worldwide, affecting an estimated 540 million people at any one time. Yet, a new Series of papers in The Lancet highlights the extent to which the condition is mistreated, often against best practice treatment guidelines.
Women who have a high cardiovascular fitness in middle age have a risk of developing dementia when older that is almost 90 percent lower than among women in average physical condition, according to a study published in the journal Neurology.
Many wives of advanced prostate cancer sufferers feel that their lives are being undermined by their husband’s illness, with nearly half reporting that their own health suffered. In addition a focus subgroup has revealed that many feel isolated and fearful, and worry about the role change in their lives as their husband’s cancer advances. This study, developed with the wives of men with metastatic prostate cancer who were being treated with hormone therapy, is amongst the first carried out on how prostate cancer affects the partners of sufferers.
