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.
Crohn's disease (CD) is a heterogeneous disorder that can involve any segment of the gastrointestinal tract.The pathogenesis of CD is unknown but is thought to involve an uncontrolled immune response triggered by an environmental factor in a genetically susceptible host.The heterogeneity of disease pathogenesis and clinical course, combined with the variable response to treatment and its associated side effects creates an environment of complex therapeutic decisions.
Despite this complexity, significant progress has been made which allows physicians to start and predict disease behavior and natural course, response to therapy and factors associated with significant side effects.
In this manuscript the data pertaining to these variables including clinical, endoscopic and the various biological and genetic markers are reviewed and the possibility of tailoring personal treatment is discussed.
Mitral valve regurgitation (MR) is the most prevalent valvular heart disease in the community, its prevalence increasing along with population aging and heart failure. While surgery remains the gold standard treatment in low-risk patients with degenerative MR, in high-risk patients and in those with functional MR, transcatheter procedures are emerging as an alternative therapeutic option. MitraClip is the device with the largest clinical experience to-date, as it offers sustained clinical benefit in selected patients. Further to MitraClip implantation, several additional approaches are developing, to better match with the extreme variability of mitral valve disease. Not only repair is evolving, initial steps towards percutaneous mitral valve implantation have already been undertaken and initial clinical experience has just started.
Pomegranate is a source of some very potent antioxidants (tannins, anthocyanins) which are considered to be also potent anti-atherogenic agents. The combination of the above unique various types of pomegranate polyphenols provides a much wider spectrum of action against several types of free radicals. Indeed, pomegranate is superior in comparison to other antioxidants in protecting low-density lipoprotein (LDL, “the bad cholesterol”) and high-density lipoprotein (HDL, “the good cholesterol”) from oxidation, and as a result, it attenuates atherosclerosis development and its consequent cardiovascular events. Pomegranate antioxidants are not free, but are attached to the pomegranate sugars, and hence were shown to be beneficial even in diabetic patients. Furthermore, pomegranate antioxidants are unique in their ability to increase the activity of the HDL-associated paraoxonase 1 (PON1), which breaks down harmful oxidized lipids in lipoproteins, in macrophages, and in atherosclerotic plaques. Finally, unique pomegranate antioxidants beneficially decrease blood pressure. All the above beneficial characteristics make the pomegranate a uniquely healthy fruit.
The Cox maze III and Cox maze IV procedures are surgical solutions for the treatment of symptomatic stand-alone atrial fibrillation. Despite their proven efficacy, these procedures have not gained widespread acceptance because of the invasiveness, complexity, and technical difficulty. Endocardial pulmonary vein isolation is the cornerstone of percutaneous catheter ablation for atrial fibrillation. It is currently accepted as an invasive therapy, if rhythm control has failed using antiarrhythmic drugs or electrical cardioversions. Pulmonary vein isolation is reported to be effective in 60%–85% of patients with paroxysmal atrial fibrillation and in 30%–50% of patients with persistent atrial fibrillation. A second or third ablation is often necessary to achieve these results, and complications may occur in up to 6% of patients.
Surgical treatment of atrial fibrillation has seen important improvements in the last decade. New technologies have simplified creation of transmural lesions on the beating heart through a less-invasive, thoracoscopic procedure. This allows for pulmonary vein isolation, isolation of the posterior wall, and left atrial appendage exclusion—usually combined with ganglionic plexi evaluation and destruction. Nonethe¬less, it is still uncertain whether these procedures are effective in restoring permanent sinus rhythm since transmurality of a lesion set cannot be guaranteed with current ablation catheters on the beating heart.
In an attempt to limit the shortcomings of an endo- or an epicardial technique, a hybrid approach has recently been introduced. This approach is based on a close collaboration between the surgeon and the electrophysiologist, employing a patient-tailored procedure which is adapted to the origin of the patient’s atrial fibrillation and takes into consideration triggers and substrate. Using a mono- or bilateral energy source, a thoracoscopic epicardial approach is combined with a percutaneous endocardial ablation in a single-step or in a sequential-step procedure.
This article provides our experience and an overview of the current knowledge in the hybrid treatment of stand-alone atrial fibrillation.
The surgical repair of complex congenital heart defects frequently requires additional tissue in various forms, such as patches, conduits, and valves. These devices often require replacement over a patient’s lifetime because of degeneration, calcification, or lack of growth. The main new technologies in congenital cardiac surgery aim at, on the one hand, avoiding such reoperations and, on the other hand, improving long-term outcomes of devices used to repair or replace diseased structural malformations. These technologies are: 1) new patches: CorMatrix® patches made of decellularized porcine small intestinal submucosa extracellular matrix; 2) new devices: the Melody® valve (for percutaneous pulmonary valve implantation) and tissue-engineered valved conduits (either decellularized scaffolds or polymeric scaffolds); and 3) new emerging fields, such as antenatal corrective cardiac surgery or robotically assisted congenital cardiac surgical procedures. These new technologies for structural malformation surgery are still in their infancy but certainly present great promise for the future. But the translation of these emerging technologies to routine health care and public health policy will also largely depend on economic considerations, value judgments, and political factors.
Between the 1950s and 1980s, scientists were focusing mostly on how the genetic code was transcribed to RNA and translated to proteins, but how proteins were degraded had remained a neglected research area. With the discovery of the lysosome by Christian de Duve it was assumed that cellular proteins are degraded within this organelle. Yet, several independent lines of experimental evidence strongly suggested that intracellular proteolysis was largely non-lysosomal, but the mechanisms involved have remained obscure. The discovery of the ubiquitin-proteasome system resolved the enigma. We now recognize that degradation of intracellular proteins is involved in regulation of a broad array of cellular processes, such as cell cycle and division, regulation of transcription factors, and assurance of the cellular quality control. Not surprisingly, aberrations in the system have been implicated in the pathogenesis of human disease, such as malignancies and neurodegenerative disorders, which led subsequently to an increasing effort to develop mechanism-based drugs.
Objective: This pilot study was designed to describe changes in spiritual well-being (SWB), spiritual coping, and quality of life (QOL) in patients with brain cancer or other neurodegenerative diseases participating in a chaplain-led spiritual life review interview and development of a spiritual legacy document (SLD).
Methods: Eligible participants were enrolled and completed baseline questionnaires. They were interviewed by a board-certified chaplain about spiritual influences, beliefs, practices, values, and spiritual struggles. An SLD was prepared for each participant, and one month follow-up questionnaires were completed. Two cases are summarized, and spiritual development themes are illustrated within a spiritual development framework.
Results: A total of 27 patients completed baseline questionnaires and the interview; 24 completed the SLD, and 15 completed the follow-up questionnaire. Increases in SWB, religious coping, and QOL were detected. The majority maintained the highest (best) scores of negative religious coping, demonstrating minimal spiritual struggle.
Conclusions: Despite the challenges of brain cancers and other neurodegenerative diseases, participants demonstrated improvements in SWB, positive religious coping, and QOL. Patient comments indicate that benefit is related to the opportunity to reflect on and integrate spiritual experiences and to preserve them for others. Research with a larger, more diverse sample is needed, as well as clinical applications for those too vulnerable to participate in longitudinal follow-up.
While the essence of nursing has long been whole person (body, mind, and spirit) and whole system-focused, in reality the contemporary practice of nursing in many settings around the globe has become increasingly fragmented and de-stabilized. Nursing shortages in many parts of the world are significant, and hierarchies and bureaucracies often remove nurses from the point of care, be that the bedside, home, or clinic, replacing them with less skilled workers and filling their time with documentation and other administrative tasks. Integrative nursing is a framework for providing whole person/whole system care that is relationship-based and person-centered and focuses on improving the health and wellbeing of caregivers as well as those they serve. It is aligned with what is being called the “triple aim” in the United States—an effort focused on improving the patient experience (quality and satisfaction), improving the health of populations, and reducing the cost of care. The principles of integrative nursing offer clear and specific guidance that can shape and impact patient care in all clinical settings.
The human body hosts rich and diverse microbial communities. Our microbiota affects the normal human physiology, and compositional changes might alter host homeostasis and, therefore, disease risk. The microbial community structure may sometimes occupy discrete configurations and under certain circumstances vary continuously. The ability to characterize accurately the ecology of human-associated microbial communities became possible by advances in deep sequencing and bioinformatics analyses.
