The term sarcopenia describes the loss of skeletal muscle mass, strength, and function in old age. As the world population continues to grow older, more attention is given to the phenomena of sarcopenia and the search for strategies of prevention and treatment. The progression of sarcopenia is affected by age-related physiological and systemic changes in the body, including alterations in skeletal muscle tissue, hormonal changes, increased inflammatory activities, and oxidative stress. Sarcopenia progression is also affected by lifestyle factors which are far more controllable. These factors include various aspects of nutrition, physical activity, exercise, alcohol intake, and tobacco use. Raising the public awareness regarding the impact of these factors, as causes of sarcopenia and potential strategies of prevention and treatment, is of great importance. In this review we aim to describe various lifestyle factors that affect the etiology, prevention, and treatment of sarcopenia.
Age as a risk for diseases: We offer a different approach to delaying or preventing age-related diseases. To understand the necessity for a new approach we have plotted the mortality rates in Israelis in relation to specific age groups and diseases...(Click below to read the entire editorial.)
Among the wide-spectrum contribution of the Rambam – the Maimonides – in philosophy to the word and to Judaism are his ideas on the body and on the soul and on the relations between them. His major approaches in these subjects are the following: 1) The body is the home of the soul, and the soul guides the body. That means the body and the soul are one unit. 2) The soul has five virtual parts. Each part is responsible for another activity in the human being. 3) Except for the treatment of diseases of the body and the soul with drugs, foods, physical exercise, etc., the Rambam believes that maintaining the health – of the body and of the soul – lies first of all, and probably exclusively, in observing the commandments and improving one’s ways, morals and conduct up to their highest levels, toward all of the world’s creatures. 4) The Rambam is of the opinion that one needs to persist in learning the Torah. One should worship God with awe and love and observe good values and virtues. All of these build the frameworks that maintain mental health and strengthen man’s abilities to develop skills for maintaining bodily health. This is so because body and soul are one – which is the basis of the Rambam’s philosophy of health and medicine.
This manuscript is a survey of the halachic attitudes toward organ transplant procedures from a living donor which can be defined as life-saving procedures for the recipient or at least life-prolonging proce-dures. Three fundamental problems concerning the halachic aspects of such transplantation are dis-cussed in detail: the danger to the donor, donation under coercion, and the sale of organs and tissues. The terms “halacha” and “Jewish law” are defined in the introduction.
This paper examines the morality of schemes of payment to live donors/sellers of organs for transplantation. Following empirical and historical evidence it is argued that consent to sell organs is substantially different from consent to ordinary business transactions and that legalization of exchanges of organs with financial benefits deviates significantly from the scope of liberal toleration and human rights. Although altruistic giving is commendable, it is immoral for society to benefit from them without conferring to the donors benefits such as health and nursing insurance for life. Non-alienable and non-fungible benefits of this kind are moral as incentives to organ donation/giving
The physician-scientist represents the medical-scientific version of the “triple threat” athlete. Yet, in medicine as in sports, specialization and business are ever more in the forefront. As the field of medicine evolves, it is likely that the role of the physician, the scientist, and the physician-scientist will continue to change. Whether this is for the good or bad will only be known in hindsight.
Results of clinical studies are often contradictory in real time, and in other instances therapies may be adopted due to information from clinical studies where the data may be premature or resulting from small studies. Much of the data may have inherent selection biases, and their interpretation may be confusing and difficult. The hematological literature is full of such examples, and this review will describe some such instances in the hope of introducing both a cautionary note and encouraging more precise description of study conditions as well as an appreciation of the importance of allowing data from clinical studies to mature. Several examples will be drawn from clinical studies in lymphomas, leukemia, and bone marrow transplantation.
The first Jewish medical graduates at the University of Padua qualified in the fifteenth century. Indeed, Padua was the only medical school in for most of the medieval period in Europe where Jewish students could study freely. Though Jewish students came to Padua from many parts of Europe the main geographical sources of its Jewish students were from the Venetian lands. However, the virtual Padua monopoly on Jewish medical education came to an end during the seventeenth century as the reputation of the Dutch medical school in Leiden grew. For Jews seeking to enter the medical profession aspiring medieval Jewish physicians Padua was, for around three hundred years, the first, simplest and usually the only choice.
Cardiovascular disease (CVD), associated with vascular atherosclerosis, is the major cause of death in Western societies. Current risk estimation tools, such as Framingham Risk Score (FRS), based on evaluation of multiple standard risk factors, are limited in assessment of individual risk. The majority (about 70%) of the general population is classified as low FRS where the individual risk for CVD is often underestimated but, on the other hand, cholesterol lowering with statin is often excessively administered. Adverse effects of statin therapy, such as muscle pain, affect a large proportion of the treated patients and have a significant influence on their quality of life.
Coronary artery calcification (CAC), as assessed by computed tomography, carotid artery intima-media thickness (CIMT), and especially presence of plaques as assessed by B-mode ultrasound are directly correlated with increased risk for cardiovascular events and provide accurate and relevant information for individual risk assessment. Absence of vascular pathology as assessed by these imaging methods has a very high negative predictive value and therefore could be used as a method to reduce significantly the number of subjects who, in our opinion, would not benefit from statins and only suffer from their side-effects.
In summary, we suggest that in very-low-risk subjects, with the exception of subjects with low FRS with a family history of coronary artery disease (CAD) at young age, if vascular imaging shows no CAC or normal CIMT without plaques, statin treatment need not be administered.
Medicine in the Middle Ages was, and ever since remained, one of the main preoccupations of the professionally restricted Jews. One of the medical dynasties on the Iberian peninsula was the Bueno (Bonus) family. Following the expulsion of the Jews from Spain and their spread in Europe, these Iberian physicians became successful everywhere—just as the Buenos were in the Netherlands.
