Bone Morphogenetic Protein-4 Mediates Cardiac Hypertrophy, Apoptosis, and Fibrosis in Experimentally Pathological Cardiac Hypertrophy [Original Articles]
In this study, we investigated the role of BMP4 in cardiac hypertrophy, apoptosis, and fibrosis in experimentally pathological cardiac hypertrophy. The in vivo pathological cardiac hypertrophy models were induced by pressure-overload and angiotensin (Ang) II constant infusion in mice, and the in vitro model was induced by Ang II exposure to cultured cardiomyocytes. The expression of BMP4 increased in pressure overload, Ang II constant infusion-induced pathological cardiac hypertrophy, but not in swimming exercise-induced physiological cardiac hypertrophy in mice. BMP4 expression also increased in Ang II–induced cardi...

Risk factors identified for prolonged sports concussion symptoms
(University of Washington) Clear, identifiable factors signal whether an athlete will experience concussive symptoms beyond one week. Athletes who have four or more symptoms at initial injury were more likely to have persistent concussive symptoms. Drowsiness, concentration difficulties, nausea and sensitivity to light and noise were also associated with longer-lasting concussive symptoms. There was little correlation between loss of consciousness and persistent symptoms. Risk factors for prolonged concussion symptoms differ for football and non-football sports concussions.

Gastrostomy tube placement in patients with hypopharyngeal cancer treated with radiotherapy or chemoradiotherapy: Factors affecting placement and dependence
ConclusionApproximately one third of patients with hypopharyngeal tumors treated on organ preservation regimens may be able to avoid g‐tube placement, but further research is needed to identify clinical factors that predict g‐tube placement in this population. A posterior hypopharyngeal wall primary and smoking history correlated with longer gastrostomy tube dependence. Adherence to aggressive targeted swallowing exercise regimens may help to prevent long‐term dependence on feeding tubes. © 2013 Wiley Periodicals, Inc. Head Neck, 2013

Prevention and management of excessive gestational weight gain: a survey of overweight and obese pregnant women
Conclusions: These data suggest a lack of awareness amongst overweight and obese women regarding excessive gestational weight gain. Monitoring of gestational weight gain, and approaches for its management, should be formally integrated into routine antenatal care. Barriers to the uptake of resources to address weight gain are numerous and must be considered in the design of future interventions and services.

6 Signs that ‘Monday Morning Blues’ May Be an Emotional Alarm
Read various website about how to combat the “Monday Blues” and you’ll find pretty much the same advice in all of them: Get extra sleep Sunday night. Give yourself a jolt of cold water in your Monday morning shower. Have some coffee. Make sure to put something on your Monday “to do” list that gives you something to look forward to. All are good ideas if the problem merely is that you need a jumpstart to the work week. But such suggestions are beside the point if there is a real and important underlying issue that needs to be addressed. Sometimes the resistance to Monday is an inner emotional alarm go...

Sarcopenia, Cachexia and Congestive Heart Failure in the Elderly.
Abstract Skeletal muscle abnormalities and loss are frequently present in patients with mild or moderate cardiac heart failure (CHF) and may contribute to fatigue and dyspnea. These muscle abnormalities may be associated with age related body composition changes, such as sarcopenia. Muscle damage has also been observed in subjects with cardiac cahexia, a serious CHF complication, associated with poor prognosis independently of functional disease severity, age, and measures of exercise capacity and cardiac function. Loss of muscle mass is a feature of cachexia, whereas most sarcopenic subjects are not cachectic. I...

Sports physicians, ethics and antidoping governance: between assistance and negligence.
This study shows that some sports physicians involved in recent positive doping cases are insufficiently aware of the nuances of doping regulations and, most importantly, of the list of prohibited substances. Moreover, several team doctors are shown to have exercised poor judgement in relation to these matters with the consequence that athletes are punished for doping offences on the basis of doctors' negligence. In such circumstances, athletes' rights are jeopardised by a failure of the duty of care that (sports) physicians owe their athlete patients. We argue that, with respect to the World Anti Doping Code, antidoping g...

Gene doping: an overview and current implications for athletes.
Abstract The possibility of gene doping, defined as the transfer of nucleic acid sequences and/or the use of normal or genetically modified cells to enhance sport performance, is a real concern in sports medicine. The abuse of knowledge and techniques gained in the area of gene therapy is a form of doping, and is prohibited for competitive athletes. As yet there is no conclusive evidence that that gene doping has been practiced in sport. However, given that gene therapy techniques improve continuously, the likelihood of abuse will increase.A literature search was conducted to identify the most relevant proteins bas...

A comparison of exercise type and intensity on the noninvasive assessment of skeletal muscle mitochondrial function using near-infrared spectroscopy
Near-infrared spectroscopy (NIRS) can be used to measure muscle oxygen consumption (mVO2) using arterial occlusions. The recovery rate of mVO2 after exercise can provide an index of skeletal muscle mitochondrial function. The purpose of this study was to test the influence of exercise modality and intensity on NIRS measurements of mitochondrial function. Three experiments were performed. Thirty subjects (age: 18–27 yr) were tested. NIRS signals were corrected for blood volume changes. The recovery of mVO2 after exercise was fit to a monoexponential curve, and a rate constant was calculated (directly related to mitoch...

Vasoconstrictor responsiveness during hyperbaric hyperoxia in contracting human muscle
Large increases in systemic oxygen content cause substantial reductions in exercising forearm blood flow (FBF) due to increased vascular resistance. We hypothesized that 1) functional sympatholysis (blunting of sympathetic α-adrenergic vasoconstriction) would be attenuated during hyperoxic exercise and 2) α-adrenergic blockade would limit vasoconstriction during hyperoxia and increase FBF to levels observed under normoxic conditions. Nine male subjects (age 28 ± 1 yr) performed forearm exercise (20% of maximum) under normoxic and hyperoxic conditions. Studies were performed in a hyperbaric chamber at 1 a...

Supportive care for women with recurrent miscarriage: a survey to quantify women's preferences
CONCLUSIONS Women with RM preferred a plan for the first trimester that involved one doctor, ultrasounds and the exercise of soft skills, like showing understanding, listening skills, awareness of obstetrical history and respect towards the patient and their miscarriage, by the health care professionals. In the event of a miscarriage, women prefer aftercare. Women from ethnic minorities and women who were not pregnant during the questionnaire investigation were the two patient groups who preferred the most supportive care options. Tailor-made supportive care can now be offered to women with RM.
