Nutritional medicine presents significant educational and clinical challenges worldwide. Major issues include physician shortages as a result of inadequate training, increasing prevalence of metabolic diseases, such as obesity, diabetes, and atherosclerosis, incorporation of molecular medicine into our understanding of nutrition, and lastly, an emergent transcultural variable that affecting implementation strategies. Examples of translating specific molecular targets to culturally sensitive food-based therapies are given.

Some obese individuals do not get cardiovascular disease, diabetes, or certain cancers associated with obesity. These healthy obese individuals exercise regularly and reduce circulating levels of inflammatory mediators which are associated with the complications of obesity. ⋯ Exercise, by reducing the excess storage of fat in these bloated fat cells, reduces the levels of circulating inflammatory mediators. The processes of gathering and creating new energy-rich substances, storing energy, and consuming energy-rich substances, and the specific contribution of several hormones to this process, are reviewed.

Experimental and clinical findings strongly support the concept that thyroid hormone (TH) plays a fundamental role in the cardiovascular (CV) homeostasis. CV diseases represent a major public health care and economic problem being one of the principal causes of morbidity, mortality and hospitalization. In particular, chronic heart failure (HF) is one of the most common reasons for general practitioners consultations in people >65-70 years old. ⋯ In HF, the main and earlier alteration of the thyroid function is referred to as "low-T3" syndrome characterized by the reduction in serum total T3 and free T3 with normal levels of thyroxine (T4) and thyrotropin (TSH). This syndrome may affect till one-third of advanced HF patients. The main goal of this mini-review is to examine the main pathophysiological and clinical links between an altered thyroid metabolism and CV diseases, namely HF during progression of disease from organ specific to systemic disorder.

Estimation of the risk of revisit to the emergency department (ED) soon after discharge in the older population may assist discharge planning and targeting of post discharge intervention in high risk patients. In this study we sought to derive a risk prediction calculator for this purpose. In a prospective observational study in two tertiary ED, we conducted a comprehensive assessment of people aged 65 and over, and followed them for a minimum of 28 days post discharge. ⋯ Revisit probability was weighted towards chronic and difficult to modify risk factors such as depression, malignancy and cognitive impairment. We conclude that the risk of revisit post discharge is calculable using a probability nomogram. However, revisit is largely related to immutable factors reflecting chronic illness burden, and does not necessarily reflect poor ED care during the initial index presentation.
