Sir Themistocles Zammit : his honours and an annotated bibliography of his medical work
Get PDFSir Themistocles Zammit was born 30th September 1864 and died 2nd November 1935. Dr. Paul Cassar wrote that Zammit “is, in my view, Malta’s most distinguished man”. He was scientist, doctor, chemist, archaeologist, writer and statesman, yet there has been no proper biography of him and no complete list of his publications and only few of his personal papers survive. It is difficult to trace his career and there seem to be few reminiscences about him. In this article the author compiles an annotated bibliography of the medical papers of Sir. T. Zammit.peer-reviewe

Insulin resistance in cardiovascular disease, uremia, and peritoneal dialysis
No full textDiabetic nephropathy is highly correlated with the occurrence of other complications of type 1 diabetes (T1D) and type 2 diabetes (T2D) mellitus; for example, hypertension with cardiovascular disease (CVD) being the most frequent cause of death in patients with end-stage renal disease and undergoing renal dialysis. Hyperglycemia and insulin resistance (IR) are responsible for the micro- and macrovascular complications of diabetes through different mechanisms. In particular, IR plays a key role in the etiology of atherosclerosis in both diabetic and non-diabetic patients. IR – exacerbated by organ-level selectivity – is more important than glycemic control per se in determining cardiovascular outcomes. This may be exacerbated by the fact that IR is organ and pathway specific due to the only selective loss of sensitivity to insulin action of specific pathways/processes. Therefore, it is counterintuitive that the use of peritoneal dialysis (PD) in (frequently) diabetic renal disease patients should involve their exposure to high daily doses of glucose peritoneally. In view of the controversy about the causal association between glucose load and CVD in PD patients, we discuss the role that selective IR may play in the progression of CVD in diabetic renal end-stage patients. In discussing these associations, we propose that reducing glucose exposure in PD solutions may be beneficial especially if coupled with strategies that address IR directly, and the avoidance of excessive use of insulin treatment in T2D. © 2021 Elsevier Lt
Carnitine, mitochondrial function and therapy
No full textCarnitine is important for cell function and survival primarily because of its involvement in the multiple equilibria between acylcarnitine and acyl-CoA esters established through the enzymatic activities of the family of carnitine acyltransferases. These have different acyl chain-length specificities and intracellular compartment distributions, and act in synchrony to regulate multiple aspects of metabolism, ranging from fuel-selection and -sensing, to the modulation of the signal transduction mechanisms involved in many homeostatic systems. This review aims to rationalise the extensive range of experimental and clinical data that have been obtained through the pharmacological use of L-carnitine and its short-chain acylesters, over the past two decades, in terms of the basic biochemical mechanisms involved in the effects of carnitine on the various cellular acyl-CoA pools in health and disease.

How to Improve the Biocompatibility of Peritoneal Dialysis Solutions (without Jeopardizing the Patient’s Health)
Get PDFPeritoneal dialysis (PD) is an important, if underprescribed, modality for the treatment of patients with end-stage kidney disease. Among the barriers to its wider use are the deleterious effects of currently commercially available glucose-based PD solutions on the morphological integrity and function of the peritoneal membrane due to fibrosis. This is primarily driven by hyperglycaemia due to its effects, through multiple cytokine and transcription factor signalling—and their metabolic sequelae—on the synthesis of collagen and other extracellular membrane components. In this review, we outline these interactions and explore how novel PD solution formulations are aimed at utilizing this knowledge to minimise the complications associated with fibrosis, while maintaining adequate rates of ultrafiltration across the peritoneal membrane and preservation of patient urinary volumes. We discuss the development of a new generation of reduced-glucose PD solutions that employ a variety of osmotically active constituents and highlight the biochemical rationale underlying optimization of oxidative metabolism within the peritoneal membrane. They are aimed at achieving optimal clinical outcomes and improving the whole-body metabolic profile of patients, particularly those who are glucose-intolerant, insulin-resistant, or diabetic, and for whom daily exposure to high doses of glucose is contraindicated
The osmo-metabolic approach: a novel and tantalizing glucose-sparing strategy in peritoneal dialysis.
Get PDFPeritoneal dialysis (PD) is a viable but under-prescribed treatment for uremic patients. Concerns about its use include the bio-incompatibility of PD fluids, due to their potential for altering the functional and anatomical integrity of the peritoneal membrane. Many of these effects are thought to be due to the high glucose content of these solutions, with attendant issues of products generated during heat treatment of glucose-containing solutions. Moreover, excessive intraperitoneal absorption of glucose from the dialysate has many potential systemic metabolic effects. This article reviews the efforts to develop alternative PD solutions that obviate some of these side effects, through the replacement of part of their glucose content with other osmolytes which are at least as efficient in removing fluids as glucose, but less impactful on patient metabolism. In particular, we will summarize clinical studies on the use of alternative osmotic ingredients that are commercially available (icodextrin and amino acids) and preclinical studies on alternative solutions under development (taurine, polyglycerol, carnitine and xylitol). In addition to the expected benefit of a glucose-sparing approach, we describe an 'osmo-metabolic' approach in formulating novel PD solutions, in which there is the possibility of exploiting the pharmaco-metabolic properties of some of the osmolytes to attenuate the systemic side effects due to glucose. This approach has the potential to ameliorate pre-existing co-morbidities, including insulin resistance and type-2 diabetes, which have a high prevalence in the dialysis population, including in PD patients
Brighella, the Maltese alphabet, Manzoni and Thezan the lexicographer
Get PDFIn the first part of the article, the author discusses Don Giuseppe Zammit, who wrote under the pen-name Brighella. Zammit was a prolific writer in Italian, Latin but most importantly in Maltese. He mainly wrote in satirical newspapers such as Il Hatar, targeting the British powers in Malta. Zammit also uses this platform to highlight problems related to the Maltese alphabet to which he references the French linguist Thezan.
In the second part of the article, the author compares and contrasts the influence that Maltese and Sicilian had on each other which can be clearly seen in the proverbs used by both islands - sometimes even referring to each other or historical events.peer-reviewe
A Friend In Hope: a Story About Hope\u27s Journey with a Brain Tumour by M. Zammit & E. Dornbusch
No full textZammit, Marisa, and Erica Dornbusch. A Friend In Hope: a Story About Hope\u27s Journey with a Brain Tumour. Brain Tumor Foundation of Canada, 2008.Zammit, Marisa, Erica Dornbusch, and Carole Baillargeon. Mon amie Claire: L\u27histoire de Claire et de sa tumeur cérébrale. Foundation canadienne des tumeurs cérébrales, 2009.Zammit, Marisa, Erica Dornbusch, and Rocco Speranza. La mia amica Speranza : Speranza e il suo tumore cerebrale. Fondazione canadese del tumore cerebrale, 2008.In an interview with Daytime television, available on YouTube, author Marisa Zammit explains how the Brain Tumour Foundation of Canada contacted her as an established freelance copy writer to come up with a positive story of hope for and about children with brain tumours. According to Susan Marshall, executive director of the Foundation, no other storybook existed for elementary school aged children in Canada before 2008, when the book was published. It is the personal connection, having a child diagnosed with a brain tumour at the age of 4,that motivated Sharon to commission the publication of A Friend in Hope. Marisa had worked previously with illustrator Erica Dornbusch, who had published other storybooks (e.g. Finding Kate\u27s shoes , Mrs. Goodstory) in the past. Marisa is now a school teacher librarian at Holy Cross Catholic Secondary School in Strathroy, Ontario and she has read the book to her students.A Friend in Hope has definitely accomplished its main objective of giving children, parents, and friends a positive and hopeful outlook on the brain tumour journey. Amy Mathias, the Online Community Engagement Coordinator of the Foundation, indicated that 15,000 copies of the book had been distributed in time for the organization’s 30th Anniversary in 2012. It is thanks to the Ronald McDonald House Charities that printing and distribution of the book were possible. The book addresses a very real need not only in alleviating young patients’ fears, but also in explaining brain tumours and their medical implications to children’s teachers and classmates. In turn, adults diagnosed with brain tumours may also use the storybook to approach the subject with their children.As for the translated versions of the book, Pia di Bacco helped translate from English into French by enlisting the support of youth and staff at her school in Montreal. Similarly, her godson Rocco Speranza commissioned grades 4, 5, and 6 youth and staff at the École East Hill School’s Italian program to translate the storybook from English and French into Italian. The motivation in both translation cases was a result of a family member or a student being diagnosed with a brain tumour and the belief in educating youth about brain tumours. Schools across the English Montreal School Board and beyond in Italy, Australia, Argentina, and the USA have also benefited from the storybook.The story is written from the perspective of a young brain tumour patient’s best friend, Danny, Daniel, or Daniele in English, French, and Italian respectively. Danny is trying to understand and, most of all, support his “best buddy,” Hope, who begins her brain tumour journey. As the author Marisa Zammit expressed in the Daytime interview, Hope, or in Italian Speranza, received that name because “it is hope [speranza] that buoys the character through the hardships of the story.” In French, the character’s name is Claire, whose Latin origin “clarus” means “clear, bright, celebrated” and by extension the word “clear”. The French name too, therefore, is representative of her personality and journey.Part of the story involves references to some of the medical treatments that Hope undergoes: MRI, pharmaceutical drugs, radiation therapy, a special helmet and mouthguard, a hospital’s child life centre, and the effects of various treatments on Hope. In every instance, the story uses the narrator’s voice and point of view to express Hope’s various experiences, Danny’s reactions to them, and his own fears. It is a child’s imagination which makes this topic bearable and allows the illustrations to become particularly powerful, when, for example, Danny sees Hope take some medication, which she says will help her “feel well enough to play with [him].” The illustration, in this case, represents a mountain scape and the children’s game of climbing pillows and cushions as if they were mountain climbers, because as Hope says the medication she takes is the “same medicine mountain climbers use,” (ie. dexamethasone). Another exceptional illustration is the one representing an oceanic world with an octopus and fish, which is how Hope faces the MRI machine and transforms it into a submarine. The illustrations are identical across the translations and the English source text, except for one image representing a hockey player in what appears to be Toronto Maple Leafs colours; however, in the French and Italian translations, which originated in Montreal, the team colours were changed to those of the Montreal Canadiens. Habs fans will no doubt appreciate the sensitivity of the illustrator.All in all the story is very well written and the language is suitable for children from grades 2 to 4; however the concepts that are addressed also make this book relevant to higher grade levels. That said, some grammatical inaccuracies exist within the French translation. Public and school libraries would benefit from access to this book, as would hospital library patrons and those who use Faculty of Education libraries. The health education elements of the story are presented in a very appropriate yet realistic manner for the target audience, who will appreciate having access to such a unique resource.Highly Recommended: 4 out of 4 stars Reviewer: Denis LacroixDenis Lacroix has worked at the University of Alberta Libraries since 2003. He is the romance languages and classics librarian and enjoys reading in French, Spanish, and Italian
