The term sociotype has been introduced to describe the dynamic relationship of an individual with his/her social environment throughout life. The sociotype is a conceptual framework to highlight, in addition to bio-medical pathways, the psycho-social and environmental factors necessary to understand responses to life stresses and patient self-management for chronic illness. The sociotype interacts with genotype expression through mate selection and metabolic programming, and with the phenotype to determine adaptation throughout life from birth to old age. Following on the work of Antonovsky, Engel, and McEwen, and others in the life and social sciences, the sociotype details and expands the many factors generally included in the environmental influences on a person’s life identified here as the domains of health, relationships, and environment. Physiological mediators for sociotypic influences include: adrenal steroids and the sympathetic nervous system (allostatic load), and oxytocin (social neuroscience). The biological pathways are multiple through nutrition (essential dietary-derived amino- and fatty acids for neurotransmitter synthesis, caloric restriction, and diet–gene interactions), epigenesis, and metabolic programming. Nutrition influences growth and development, fertility and longevity, and also determines susceptibility to non-communicable diseases such as cardiovascular disease and cancer, and particularly diabetes and obesity, through in-utero effects, the development of intestinal flora (microbiome), and chronic stress. Thus the sociotype and nutrition are reciprocally related in both health and disease.
Successful deceased organ donation requires a reproducible—consistent (scientific) system that eva-luates the potential for organ donation and determines objectively whether the national system is achieving its goals. The science of organ donation also pertains to the determination of death. We are a common humanity that dies similarly— a humanity whose ultimate criterion of life resides in the function of the human brain. The recent brain death law of Israel encouragingly enables a determination of death by the loss of neurologic function but it has become complicated by a practice that may perpetuate societal misperceptions. As a result opportunities for deceased organ donation --to provide for Israelis in need of organ transplants are being lost. A statured task force of society could be assembled to convey its support for deceased donation to influence society and resolve these misperceptions.
The World Health Organization is now calling for each member state to achieve a self-sufficiency in organ donation and transplantation "equitably meeting the transplantation needs of a given population using resources from within that population". Patients should not be compelled to go to foreign countries for their organs. Israel has been a leader in the development of a model program intended to address transplant tourism. Insurance companies are no longer permitted to provide resources for Israelis to undergo illegal transplants in foreign destinations. The social necessity of a scientifically and medically applied system of deceased organ donation is now evident so that a sufficient number of organs can be available for patients from within the country they reside.
Otto Heinrich Warburg (1883–1970; not to be confused with the Zionist of the same name) was a member of an illustrious Jewish family, known for some five centuries. From humble beginnings, the family became prominent in the world for their contributions to all aspects of society. The son of a German mother and a Jewish (converted) father, Otto H. Warburg became a major contributor to medical science in the field of cancer research. Considered for Nobel Prize more than once, he finally received it in 1931 for his discovery of the nature and mode of action of the cellular respiratory enzyme. Warburg’s personality was controversial: he was intolerant of opposing scientific views yet tolerant toward Nazi abuses. Accused of collaboration under the Nazi regime, Otto H. Warburg was nevertheless readmitted to the global scientific community after World War II. His contribution to cancer research remains influential to this day and has been superseded by discoveries that have built upon his work.
The “curative potential” in almost any clinical setting depends on a caregiver establishing and maintaining an empathic connection with patients so as to achieve “narrative competence” in discerning and acting in accord with their preferences and best interests. The “narrative medicine” model of shared “close reading of literature and reflective writing” among clinicians as a means of fostering a capacity for clinical empathy has gained validation with recent empirical studies demonstrating the enhancement of theory of mind (ToM), broadly conceived as empathy, in readers of literary fiction. Talmudic legends, like that of Rabbi Judah’s death, are under-appreciated, relevant sources of literary fiction for these efforts. The limitations of narrative medicine are readily counterbalanced by simultaneously practiced attention to traditional bioethical principles, including—especially—beneficence, non-maleficence, and autonomy.
This Supplement of Rambam Maimonides Medical Journal presents the abstracts from the Fourteenth Annual Rambam Research Day. These abstracts represent the newest basic and clinical research coming out of Rambam Health Care Campus—research that is the oxygen for education and development of tomorrow’s generation of physicians. Hence, the research presented on Rambam Research Day is the foundation for understanding patient needs and improving treatment modalities. Bringing research from the bench to the bedside and from the bedside to the community is at the heart of Maimonides’ scholarly and ethical legacy.
The strong relationship between cardiovascular diseases (CVD), atherosclerosis, and endogenous or exogenous lipids has been recognized for decades, underestimating the contribution of other dietary components, such as amino acids, to the initiation of the underlying inflammatory disease. Recently, specific amino acids have been associated with incident cardiovascular disorders, suggesting their significant role in the pathogenesis of CVD. Special attention has been paid to the group of branched-chain amino acids (BCAA), leucine, isoleucine, and valine, since their plasma values are frequently found in high concentrations in individuals with CVD risk. Nevertheless, dietary BCAA, leucine in particular, have been associated with improved indicators of atherosclerosis. Therefore, their potential role in the process of atherogenesis and concomitant CVD development remains unclear. Macrophages play pivotal roles in the development of atherosclerosis. They can accumulate high amounts of circulating lipids, through a process known as macrophage foam cell formation, and initiate the atherogenesis process. We have recently screened for anti- or pro-atherogenic amino acids in the macrophage model system. Our study showed that glycine, cysteine, alanine, leucine, glutamate, and glutamine significantly affected macrophage atherogenicity mainly through modulation of the cellular triglyceride metabolism. The anti-atherogenic properties of glycine and leucine, and the pro-atherogenic effects of glutamine, were also confirmed in vivo. Further investigation is warranted to define the role of these amino acids in atherosclerosis and CVD, which may serve as a basis for the development of anti-atherogenic nutritional and therapeutic approaches.
Objective: To review current medical literature on the risks and potential benefits of e-cigarette use and its permissibility under Jewish law.
Methods: A survey of current medical literature about the risks and potential benefits of e-cigarette use, and a review of existing rabbinic literature regarding both combustible and e-cigarette products.
Results: E-cigarettes contain fewer harmful materials than do combustible cigarettes. However, they are not risk-free. Their skyrocketing use among youth is of concern, as e-cigarettes lead to nicotine addiction and are a gateway to combustible cigarettes. Preliminary data indicate that e-cigarettes increase the risk of myocardial infarction, chronic obstructive pulmonary disease (COPD), and emphysema and are no more effective as aids to smoking cessation than US Food and Drug Administration (FDA)-approved interventions with acceptable safety profiles. Few halakhic decisors have opined on the permissibility of e-cigarettes, but extrapolating from halakhic discussions regarding combustible cigarettes strongly suggests that they would prohibit e-cigarettes based on government warnings and preliminary data demonstrating increased risk of cardiovascular and respiratory diseases, at the least because of possible danger (safek sakana). Among youth and pregnant women, for whom e-cigarettes are particularly dangerous and for whom the government has administered explicit warnings, a Jewish legal prohibition should be absolute. There is a unique obligation to prevent youth from obtaining these products. Jewish law might also prohibit deriving benefit from the sale or advertisement of these products.
Conclusions: Extrapolating from rabbinic literature regarding combustible cigarettes, the preliminary data establishing the dangers of e-cigarettes and the government warnings against usage would render these products prohibited under Jewish law, especially for youth and pregnant women.
Background: The use of electric bicycles (E-bikes) has dramatically increased over the last decade. E-bikes offer an inexpensive, alternative form of transport, but also pose a new public health challenge in terms of safety and injury prevention.
Objective: The aim of this study was to describe the epidemiology and severity of E-bike related injuries among children treated in the emergency department (ED) and to compare these to manual bicycle related injuries.
Methods: A retrospective observational study of all pediatric patients presenting to the ED between December 2014 and November 2015 with an injury related to E-bike or manual bicycle use. Data including demographics, diagnosis, injury severity score (ISS), and outcome were compared.
Results: A total of 196 cyclist injuries presented to the ED; 85 related to E-bike use and 111 to manual bicycle riders. The mean age of E-bikers was 13.7 years (7.5–16 years) and of manual bicycle riders was 9.9 years (3–16 years). Injuries to the head and the extremities were common in both groups. E-bikers had significantly more intra-abdominal organ injury (P=0.047). Injury severity scores were low overall, but injuries of higher severity (ISS>9) only occurred among the E-bikers.
Conclusions: Pediatric E-bike injuries tend to be more severe than those sustained during manual bicycle riding. Further research into bicycle and other road and pavement users could lead to enhanced regulation regarding E-bike usage.
The worldwide use of the transvaginal scanning route has revolutionized obstetrical and gynecologic imaging. The long, slow, and at times challenging aspects of its acceptance by the obstetrical and gynecologic community are the subject of this article. From its inception to its recent use, the dedicated doctors in the Department of Obstetrics and Gynecology at Rambam Medical Center, Haifa, Israel, were instrumental in conceiving and then collaborating with an Israeli manufacturer in the construction and worldwide use of the transvaginal ultrasound probe, resulting in the now well-known field of transvaginal sonography.
The evolution of medicine is quite remarkable and astounding. Modern medicine is successfully treating or providing long-term control of conditions which in the not-so-distant past were lethal or resulted in permanent disability. The strong emphasis on evidence-based medicine in today’s medical profession has led to a more organized approach toward evaluating the safety and efficacy of new medical treatments. Despite attempts to meet the complex needs of an ever-aging population, an almost cynical or inherent distrust of physicians in general and their medical claims is being increasingly noted. For many physicians this has led to an uncomfortable sense of professional frustration as doubt is cast on themselves or the medical profession in general when the expectations and goals of patients or their families are not achieved. The causes of this apparent malady of contemporary medicine are myriad and may be explored from various perspectives, depending on the particular issue. To understand better the issues and challenges involved, today’s medical practitioner needs to be aware of the complex mix of organizational, professional, ethical, and at times anthropological perspectives contributing to this dissonance between medical professionals and the public. Improving our insight into the forces at work in this dissonance will help medical professionals improve medical services to the public and contribute to the preservation of medicine’s admirable historical legacy.
