Impact of Increased Oxidative Stress on Cardiovascular Diseases in Women With Polycystic Ovary Syndrome

Abstract: Polycystic ovary syndrome (PCOS) is a complex disorder that affects around 5% to 10% of women of childbearing age worldwide, making it the most common source of anovulatory infertility. PCOS is defined by increased levels of androgens, abnormal ovulation, irregular menstrual cycles, and polycystic ovarian morphology in one or both ovaries. Women suffering from this condition have also been shown to frequently associate certain cardiovascular comorbidities, including obesity, hypertension, atherosclerosis, and vascular disease. These factors gradually lead to endothelial dysfunction and coronary artery calcification, thus posing an increased risk for adverse cardiac events. Traditional markers such as C-reactive protein (CRP) and homocysteine, along with more novel ones, specifically microRNAs (miRNAs), can accurately signal the risk of cardiovascular disease (CVD) in PCOS women. Furthermore, studies have also reported that increased oxidative stress (OS) coupled with poor antioxidant status significantly add to the increased cardiovascular risk among these patients. OS additionally contributes to the modified ovarian steroidogenesis, consequently leading to hyperandrogenism and infertility. The present review is therefore aimed not only at bringing together the most significant information regarding the role of oxidative stress in promoting CVD among PCOS patients, but also at highlighting the need for determining the efficiency of antioxidant therapy in these patients.

Clinical impact of cachexia on survival and outcome of cancer patients.

Abstract: Approximately one half of all cancer patients experience a complex metabolic status involving progressive exhaustion of adipose and skeletal muscle tissue. This condition, known as cachexia, is responsible for more than 20% of the overall deaths in cancer patients. Although its main mechanisms remain unknown, several hypotheses have been proposed. One of the pathogenic mechanisms involves leptin and hypothalamic neuropeptide-containing pathways. Orexigenic and anorexigenic neuropeptides are down-regulated respectively upregulated as a result of cancer. Other pathogenic theories consider tumour derived factors, such as LMF (Lipid Mobilising Factor) and PIF (Proteolysis-inducing Factor), to be responsible for the weight losing pattern of cancer patients via activation of various catabolic pathways (e.g. ubiquitin-proteasome proteolytic-pathway, etc.). Despite the controversial discussion of cachexia-inducing mechanisms it is clear that proinflammatory cytokines, such as TNFalpha, IFNgamma, IL-1, IL-6 and IL-8, are linked to all pathways that induce cachexia. Although only limited treatment exists for patients with cancer cachexia, recent studies with eicosapaentanoic acid showed promising effects in reversing weight losing pattern of cachectic patients. Cytokine targeted monoclonal antibodies, cytokine traps and genetic therapies are also evaluated for future therapeutic strategies.

In vitro biocompatibility testing of some synthetic polymers used for the achievement of nervous conduits.

Abstract: Biocompatible synthetic polymers are largely used in the bio–medical domain, tissue engineering and in controlled release of medicines. Polymers can be used in the achievement of cardiac and vascular devices, mammary implants, eye lenses, surgical threads, nervous conduits, adhesives, blood substitutes, etc. Our study was axed on the development of cytotoxicity tests for 3 synthetic polymers, namely polyvinyl alcohol, polyethylene glycol and polyvinyl chloride. These tests targeted to determine the viability and morphology of cells (fibroblasts) that were in indirect contact with the studied polymers. Cell viability achieved for all the studied synthetic polymers allowed their frame in biocompatible material category. Cell morphology did not significantly change, thus accomplishing a new biocompatibility criterion. The degree of biocompatibility of the studied polymers varied. Polyvinyl alcohol presented the highest grade of biocompatibility and polyvinyl chloride placed itself at the lowest limit of biocompatibility. The results achieved allowed the selection of those polymers that (by enhancing their degrees of biocompatibility due to the association with various biopolymers) will be used in the development of new biocompatible materials, useful in nervous conduits manufacture.

A modern method of treatment: The role of silver dressings in promoting healing and preventing pathological scarring in patients with burn wounds.

Abstract: Burn wounds are a global public health problem, which affects all countries, no matter the development stage and occurs in all age groups, from toddlers to elderly. In spite of burns being the cause of numerous household and work accidents, there are still no clear stated unanimous rules for their treatment. Every day new products appear on the market, each of them trying to prove more effective. Since ancient times, silver has been known for its antimicrobial properties, so it has been used for a long time in the treatment of burns and other types of wounds. One of the relatively modern methods of treatment is applying silver sheets on the scald lesions. In this paper, which was part of a larger study (research for a PhD thesis), concerning prevention and treatment of the post-burn pathological scars, the cases of some patients with burns, who were treated by using the above mentioned method were presented and analyzed. The results obtained by applying silver sheets were then commented and interpreted, pointing out the advantages and disadvantages compared to silver sulfadiazine creams and ointments, which have already been used at a large scale. The prevention and treatment of post-burn pathological (hypertrophic and keloid) scars is a field in which still little is known and in which there are also no clearly set therapy plans. We hope that through this research and the following ones we will manage to establish some major guidelines concerning the prevention of pathological scars, which are not only disabling, but also a major aesthetic issue for any patient, in order to obtain better outcomes.

Gallstone ileus after laparoscopic cholecystectomy.

Abstract: Gallstone ileus represents a rare complication (0,3-0,5%) of a serious, but common disease-gallstones, which affect around 10% of the population in the USA and Western Europe. Associated diseases (usually severe), elderly patients, delayed diagnosis and therapy due to late presentation to the hospital, account for the morbidity and mortality rates described in literature. We present the case of a patient with partial colon obstruction due to a large gallstone that was "lost" during an emergency laparoscopic cholecystectomy. The calculus eroded the intestinal wall, partially occluding the lumen, triggering recurrent Kerwsky-like, subocclusive episodes. The intraperitoneal abscess has spontaneously drained through the subhepatic drain and once the tube has been removed, a persistent intermittent fistula became obvious.
