    Three men aged 18, 18 and 24 years, developed hypotension and bradycardia following an acute traumatic cervical or thoracic spinal cord injury. After treatment in intensive care and 1-12 months of rehabilitation they still suffered from considerable neurological disorders. Hypotension and bradycardia are common phenomena following acute traumatic cervical and thoracic spinal cord injury. Awareness of cardiovascular complications as a possible threat for functional recovery and adequate insight in the neurological cause of hypotension and bradycardia are important issues in the acute treatment of patients with spinal cord injury. It seems sensible to admit these patients to a medium-care or intensive-care department where they can be monitored and treated by a specialised team in accordance with an adequate protocol.

    Full Text Available Both anaphylaxis and head injury are often seen in the emergency department, but they are rarely seen in combination. We present a case of a 30-year-old woman who presented with anaphylaxis with urticaria and angioedema following a minor head injury. The patient responded well to intramuscular epinephrine without further complications or airway compromise. Prior case reports have reported angioedema from hereditary angioedema during dental procedures and maxillofacial surgery, but there have not been any cases of first-time angioedema or anaphylaxis due to head injury.

    Acute lung injury (ALI) is associated with systemic inflammation and cardiovascular dysfunction. IL-6 is a biomarker of this systemic response and a predictor of cardiovascular events, but its possible causal role is uncertain. Inhaled corticosteroids and long-acting β2 agonists (ICS/LABA) down......-regulate the systemic expression of IL-6, but whether they can ameliorate the cardiovascular dysfunction related to ALI is uncertain. We sought to determine whether IL-6 contributes to the cardiovascular dysfunction related to ALI, and whether budesonide/formoterol ameliorates this process. Wild-type mice were...... these impairments (vasodilatory responses to acetylcholine, P = 0.005; cardiac output, P = 0.025). Pretreatment with the combination of budesonide and formoterol, but not either alone, ameliorated the vasodilatory responses to acetylcholine (P = 0.018) and cardiac output (P drugs also attenuated...

    2010-10-01

    Mitochondria are highly dynamic organelles with constant shape changes regulated by fusion and fission events. In addition to regulating mitochondrial morphology, mitochondrial fusion/fission is involved in fundamental mitochondrial biological processes, including mitochondrial metabolism, energization, respiration, mitochondrial membrane potential, and mtDNA stability. Dysfunction of mitochondrial dynamics has been implicated in various human diseases, especially in neurodegenerative diseases. Emerging evidence indicates that impaired expression of mitochondrial fusion proteins or their malfunction participates in oxidative stress-induced cardiovascular injury. This review will focus on recent advances of mitochondrial fusion in regulating various cellular processes in cardiovascular system.

  8. Hindfoot injuries due to landmine blast accidents.

    2002-03-01

    Landmines were initially developed as anti-tank weapons. They are still used indiscriminately and in a disorganised fashion, violating the United Nations Treaty on their use [United Nations (1980)]. The injury produced by these devices is variable depending upon the construction and strength of the landmine and body parts coming in contact with the landmine at the time of detonation. The purpose of the present study was to report the type of landmine-blast injuries of the lower limbs and the surgical options available to treat them. Twenty-eight patients, all with lower limb injuries were included in the present study. They had received injuries on the control line of the troubled Jammu and Kashmir regions in the north of Pakistan. All were male patients between the age of 13 and 55 years. A salvage procedure for the forefoot was possible on four patients only and all the rest had a below-knee amputation. Time lapsed between the injury and receiving medical help was the crucial determining factor as to the final outcome of the limb. We believe that the pattern of injury, amount of energy dissipation and part of body in contact with the landmine at the time of explosion are the main determining factors for the final outcome. If skin along with the underlying soft tissue and the neuro-vascular structures on the dorsum of the foot are spared then an attempt can be made at limb salvage.

  9. Cardiovascular disease due to accelerated atherosclerosis in systemic vasculitides.

    2013-02-01

    Patients with different forms of systemic vasculitis experience long-term morbidity and mortality caused by cardiovascular disease due to premature atherosclerosis. Epidemiologic reports of patients with GCA suggest that long-term mortality in this disease is not increased compared with the general population of the same age. The risk of a stroke, however, in particular in the vertebrobasilar territory, is increased. In addition, the occurrence of aortic aneurysmal disease and aortic dissection is also clearly increased in GCA. Mortality due to ischaemic heart disease, however, is not increased. In Takayasu arteritis accelerated atherosclerosis has been clearly documented both clinically and in autopsy reports. Atherosclerotic plaques in the carotid artery may be present in the carotid arteries especially in patients with a documented history of arteritis involving the carotid artery. It is controversial whether Kawasaki disease is associated with accelerated atherosclerosis. Young adults with a history of Kawasaki disease may have abnormal brachial artery reactivity, increased carotid IMT values and increased arterial stiffness. At autopsy examinations of KD patients, however, no significant atherosclerotic lesions are detected and carotid IMT measurements were found to be clearly different from those in young adults with familiar hypercholesterolaemia, suggesting that the remodeling process in KD is different from atherosclerosis. In ANCA-associated vasculitis (AAV), an increased mortality as a consequence of cardiovascular disease is well-documented. In these patients the relative risk for coronary heart disease is two- to fourfold that in control subjects. In addition, a similar relative risk has been found for stroke. Diabetes, hypertension, dyslipidemia, abdominal obesity (metabolic syndrome), impaired renal function, persistent proteinuria and increased production of C-reactive protein are common risk factors for premature atherosclerosis in patients with

    1997-01-01

    We report an apparently unusually high incidence of leg injury in Willow Flycatchers (Empidonax traillii) as a result of banding and color banding. Color bands and U.S. Fish and Wildlife Service (USFWS) bands applied to Willow Flycatchers from 1988-1995 resulted in an overall leg injury rate of 9.6% to birds returning to our study areas in subsequent years. Most injuries occurred on legs with only color band(s) (58.3%) or on legs with both a USFWS band and a color band (35%); only 6.7% of injuries (4/60) were due to USFWS bands alone, yielding an overall USFWS band injury rate of only 0.6%. Injuries ranged from severe (swollen, bleeding legs; a missing foot) to relatively minor (irritations on the tarsus). Amputation of the foot occurred in 33.9% of the cases. Return rates of adult injured birds in the year(s) following injury were significantly lower than for the population at large.

    A 17-year-old patient was aggressively attacked and stabbed in the dorsal region of his back by a knife. He was admitted to the emergency room of the Hammoud Hospital University Medical Center, Saida, Lebanon lying in the prone position. The neurological examination revealed that the stabbing object was fixed at the dorsal spine level at the T-7 level, where it was inserted inside the vertebral body. Luckily, the blade of the knife was parallel to the nervous tracts of the spinal cord; thus, he showed no neurological deficits. This case provides an overview of how neurosurgical principles can be applied to trauma patients with spine injuries due to close combat weapons.

    The health benefits of exercise may be attenuated by sports and recreation related injury (SRI). Though the majority of SRI are mild and self-limiting, a significant number are serious and require orthopaedic intervention. The aims of this study were to assess the burden of these serious injuries on the orthopaedic inpatient service, and to investigate potential target areas for injury prevention. All 1,590 SRI seen in the ED over a 3-month period were analysed using the Patient Information Management System to determine which patients received inpatient orthopaedic care. The medical records of those 63 patients who required inpatient care under orthopaedics were reviewed and data collected on demographic features, history, operative procedure and theatre resources, and length of hospital stay. Data were analyzed using SPSS. SRI accounted for 12.3% of all ED presentations. The principal activities resulting in injury requiring orthopaedic care were soccer, hurling and informal play e.g. trampoline. Falls made up 37% of the overall mechanism of injury but 68% of the injuries severe enough to require operative management. Most operative procedures were performed as part of a routine day trauma list but 20% were performed out of hours. This group of injuries places a significant burden on a busy trauma service. Injury prevention measures such as public education regarding falls in sport may have a role in reducing this burden.

    Full Text Available AIM This study carried out in Department of Orthopaedics, S.S. Medical College and Sanjay Gandhi Memorial Hospital, Rewa, MP to study the orthopaedic injury caused by road traffic accidents and factors responsible for these injuries. BACKGROUND Road traffic accidents are one of the major causes of death in developed as well as developing countries. India accounts for about 10% of road accident fatalities worldwide and more deaths are recorded due to traffic crashes than due to cardiovascular diseases or neoplasms. METHODS The present study was carried out on the patients injured due to road traffic injuries admitted in orthopaedic ward of Shyam Shah Medical College and associated Sanjay Gandhi Memorial Hospital, Rewa (MP, during the one-year period from 1st October 2014 to 30th September 2015. The collected data was classified and coded as per the guidelines laid down under the WHO/CDC Injury Surveillance System and ICECI. RESULTS This study showed that the majority of crash victims were males in the age group 20-44 years accounting for huge economic losses for their families and the country at large. Motorized two-wheeler accounted for 46.78% of the accidents. Out of total accident victims, 45% were drivers and riders; 49.47% of accidents occurred between 4 pm to 12 pm. Most drivers/riders mentioned had not taken safety measure (Helmet/seat belt during accident. Fractures (87.97% were the most common nature of injuries and lower limb was more commonly involved than the upper limb. CONCLUSION Road traffic accidents are preventable. Strict traffic laws and penalties have to be imposed to curb this ever growing menace.

    The molecular bases for variability in air pollutant-induced pulmonary injury due to underlying cardiovascular (CVD) and/or metabolic diseases are unknown. We hypothesized that healthy and genetic CVD-prone rat models will exhibit exacerbated response to acute ozone exposure dependent on the type and severity of disease. Healthy male 12-14-week-old Wistar Kyoto (WKY), Wistar (WS) and Sprague Dawley (SD); and CVD-compromised spontaneously hypertensive (SH), Fawn-Hooded hypertensive (FHH), stroke-prone spontaneously hypertensive (SHSP), obese spontaneously hypertensive heart failure (SHHF) and obese JCR (JCR) rats were exposed to 0.0, 0.25, 0.5, or 1.0 ppm ozone for 4 h; pulmonary injury and inflammation were analyzed immediately following (0-h) or 20-h later. Baseline bronchoalveolar lavage fluid (BALF) protein was higher in CVD strains except for FHH when compared to healthy. Ozone-induced increases in protein and inflammation were concentration-dependent within each strain but the degree of response varied from strain to strain and with time. Among healthy rats, SD were least affected. Among CVD strains, lean rats were more susceptible to protein leakage from ozone than obese rats. Ozone caused least neutrophilic inflammation in SH and SHHF while SHSP and FHH were most affected. BALF neutrophils and protein were poorly correlated when considering the entire dataset (r = 0.55). The baseline and ozone-induced increases in cytokine mRNA varied markedly between strains and did not correlate with inflammation. These data illustrate that the degree of ozone-induced lung injury/inflammation response is likely influenced by both genetic and physiological factors that govern the nature of cardiovascular compromise in CVD models.

    Although hypoglycemia may be common among neonates, brain injuries resulting from isolated neonatal hypoglycemia are rare. The condition may cause neurological symptoms such as stupor, jitteriness, and seizures, though in their absence, diagnosis delayed or difficult. Hypoglycemia was diagnosed in a three-day-old neonate after he visited the emergency department with loose stool, poor oral intake, and decreased activity, first experienced two days earlier. Two days after his visity, several episodes of seizure occurred. T2 and diffusion-weighted magnetic resonance (MR) scanning, performed at 11 days of age, revealed bilateral and symmetrical high signal intensity lesions in occipital, parietal, and temporal lobes. We report the MR findings of hypoglycemic encephalopathy in a neonate.

    Seventy-one patients with intestinal injury secondary to pelvic irradiation had predominantly large bowel lesions. Seventeen cases were treated conservatively and 54 came to surgery, 28 patients having more than one operation. Following this essentially salvage surgery there were more ileal than colonic anastomotic leaks. Thirty-four patients died during the follow-up period (2-12 years), 19 from recurrent malignancy, and nine as a result of continuing radiation effects. Seventy per cent of the patients who had a radiation fistula died as a result of malignancy. Of 42000 cases of pelvic malignancy treated by irradiation over the decade 1972-1982, surgical referrals for complications constituted 1.7%, with an overall radiation-related mortality of 0.2%. It is our opinion that colostomy alone has little part to play in this condition, and a policy based on excisional surgery is suggested.

    This paper describes a unique case of a fatal tiger attack in the wild. In the present case, a tiger fatally mauled a 34-year-old female with its claws, instead of the usual mechanism of killing by the bite injury to the neck. The autopsy revealed multiple fatal and non-fatal injuries caused by the tiger claws. The characteristic injuries due to the tooth impacts were absent as the teeth of the offending tiger were either fallen or non-functional. To the best of our knowledge, probably this rare case would be the first reported human fatality due to the tiger claw injuries in the world. The purpose of the present article is to highlight the fatal injuries due to the tiger claws, as the claw-induced fatal injuries in a tiger attack are not reported in the medico-legal literature. Moreover, this report would be an illustrative one for differentiation between the fatal injuries due to the claws and tooth impacts in a tiger attack. Furthermore, the present report establishes the importance of the tiger claws as a source of fatal injuries in a tiger attack.

    Full Text Available Background. LigaSure is a bipolar clamping device used in open and laparoscopic surgeries for producing haemostasis in vascular pedicles up to 7 mm in diameter (“Covidien LigaSure technology: consistent, reliable, trusted vessel sealing,” 2012. The use of LigaSure has made securing haemostasis and tissue dissection relatively easy especially in laparoscopic surgery; however, if not used with care it can cause damage to the surrounding structures through lateral spread of energy. Case Report. This case report discusses the induction of a thermal ureteral injury associated with the use of LigaSure. An 80-year-old gentleman was operated for bowel cancer. LigaSure was used for securing haemostasis and tissue dissection. Postoperatively, he was found to have damage to the right ureter secondary to lateral spread of energy from the jaws of LigaSure with high abdominal drain output. Conclusion. Judicious and careful use of electrosurgical devices should be done to prevent inadvertent damage to the surrounding structures. Early recognition and involvement of a urologist can prevent long-term complications.

  6. Cardiovascular Dysfunction Following Burn Injury: What We Have Learned from Rat and Mouse Models

    Directory of Open Access Journals (Sweden)

    Ashley N. Guillory

    2016-01-01

    Full Text Available Severe burn profoundly affects organs both proximal and distal to the actual burn site. Cardiovascular dysfunction is a well-documented phenomenon that increases morbidity and mortality following a massive thermal trauma. Beginning immediately post-burn, during the ebb phase, cardiac function is severely depressed. By 48 h post-injury, cardiac function rebounds and the post-burn myocardium becomes tachycardic and hyperinflammatory. While current clinical trials are investigating a variety of drugs targeted at reducing aspects of the post-burn hypermetabolic response such as heart rate and cardiac work, there is still a paucity of knowledge regarding the underlying mechanisms that induce cardiac dysfunction in the severely burned. There are many animal models of burn injury, from rodents, to sheep or swine, but the majority of burn related cardiovascular investigations have occurred in rat and mouse models. This literature review consolidates the data supporting the prevalent role that β-adrenergic receptors play in mediating post-burn cardiac dysfunction and the idea that pharmacological modulation of this receptor family is a viable therapeutic target for resolving burn-induced cardiac deficits.

    Chlorine dioxide is a commonly used water disinfectant. Toxicity of chlorine dioxide and its metabolites is rare. In experimental studies, it was shown that acute and chronic toxicity were associated with insignificant hematological changes. Acute kidney injury due to chlorine dioxide was not reported. Two cases of renal toxicity due to its metabolites, chlorate and chlorite were reported. Herein, we report a case of chlorine dioxide poisoning presenting with acute kidney injury.

    Fatty acids have an important role in providing energy for sustained contractile activity and viability of the heart. However, considerable evidence now supports a role for fatty acids in the modulation of cardiovascular pathology as well. This may be beneficial or detrimental due to the structural differences in the various fatty acids. Polyunsaturated fatty acids appear to provide important protection to the heart during ischemic reperfusion challenge. Conversely, trans fatty acids are thought to mediate detrimental cardiac effects. Potentially pathological features of ischemic cardiomyocytes may be manifested as qualitative findings in studies of myocardial infarction and atherosclerosis. These general conclusions, however, are complicated by opposing effects that different fatty acids have even within the same group (i.e. n-6 versus n-3 fatty acids within the polyunsaturated fatty acids group, and industrial versus ruminant trans fats). Understanding more about how these fatty acid species alter ischemic myocardial injury is an increasingly attractive area of research. The identification of further targets of fatty acid interactions has great potential to provide valuable information for the modulation of cardiovascular disease.

    Full Text Available OBJECTIVE - To analyze the trends in risk of death due to cardiovascular diseases in the northern, northeastern, southern, southeastern, and central western Brazilian geographic regions from 1979 to 1996. METHODS - Data on mortality due to cardiovascular, cardiac ischemic, and cerebrovascular diseases in 5 Brazilian geographic regions were obtained from the Ministry of Health. Population estimates for the time period from 1978 to 1996 in the 5 Brazilian geographic regions were calculated by interpolation with the Lagrange method, based on the census data from 1970, 1980, 1991, and the population count of 1996, for each age bracket and sex. Trends were analyzed with the multiple linear regression model. RESULTS - Cardiovascular diseases showed a declining trend in the southern, southeastern, and northern Brazilian geographic regions in all age brackets and for both sexes. In the northeastern and central western regions, an increasing trend in the risk of death due to cardiovascular diseases occurred, except for the age bracket from 30 to 39 years, which showed a slight reduction. This resulted from the trends of cardiac ischemic and cerebrovascular diseases. The analysis of the trend in the northeastern and northern regions was impaired by the great proportion of poorly defined causes of death. CONCLUSION - The risk of death due to cardiovascular, cerebrovascular, and cardiac ischemic diseases decreased in the southern and southeastern regions, which are the most developed regions in the country, and increased in the least developed regions, mainly in the central western region.

    Most ballet dancers will suffer at least one injury a year. There are numerous causes of injury in dance, and while many investigators have documented risk factors such as anatomical characteristics, past medical history, menstrual history, dance experience, length of dance training, fatigue, and stress, risk factors related to body characteristics and nutrient intake, levels of conditioning, or physical fitness parameters have only recently received the same amount of attention. The aim of the present study was, therefore, to investigate correlations between ballet injury and body fat percentage, active and passive flexibility, lower limb power, upper body and core endurance, and aerobic capacity. Low levels of aerobic fitness were significantly associated with many of the injuries sustained over a 15-week period (r=.590, p=0.034), and body fat percentage was significantly associated with the length of time a dancer was forced to modify activity due to injury (r=-.614, p=0.026). This information may be of benefit to dancers, teachers, physical therapists and physicians in dance schools and companies when formulating strategies to prevent injury.

    Oxalate nephropathy is an uncommon cause of acute kidney injury. Far rarer is its association with scleroderma, with only one other published case report in the literature. We report a case of a 75-year-old African-American female with a history of systemic scleroderma manifested by chronic pseudo-obstruction and small intestinal bacterial overgrowth (SIBO) treated with rifaximin, who presented with acute kidney injury with normal blood pressure. A renal biopsy demonstrated extensive acute tubular injury with numerous intratubular birefringent crystals, consistent with oxalate nephropathy. We hypothesize that her recent treatment with rifaximin for SIBO and decreased intestinal transit time in pseudo-obstruction may have significantly increased intestinal oxalate absorption, leading to acute kidney injury. Oxalate nephropathy should be considered in the differential diagnosis of acute kidney injury in scleroderma with normotension, and subsequent evaluation should be focused on bowel function to include alterations in gut flora due to antibiotic administration.

    Several theories about musculoskeletal pain syndromes such as whiplash-associated disorder (WAD) suggest that pain and muscle activity interact and may contribute to the chronicity of symptoms. Studies using surface electromyography (sEMG) have demonstrated abnormal muscle activation patterns of the upper trapezius muscles in the chronic stage of WAD (grade II). There are, however, no studies that confirm that these muscle reactions are initiated in the acute stage of WAD, nor that these muscle reactions persist in the transition from acute neck pain to chronic neck pain disability. We analyzed the muscle activation patterns of the upper trapezius muscles in a cohort of 92 subjects with acute neck pain due to a motor vehicle accident (MVA). This cohort was followed up in order to evaluate differences in muscular activation patterns between subjects who have recovered and those subjects who have not recovered following an acute WAD and developed chronic neck pain. sEMG parameters were obtained at 1, 4, 8, 12, and 24 weeks after an MVA. The level of muscle reactivity (the difference in pre- and post-exercise EMG levels) and the level of muscle activity during an isometric and a dynamic task were used as EMG parameters. The results revealed no elevated muscle reactivity either in the acute stage, or during the follow-up period. The results of both the isometric and dynamic task, showed statistically significant different EMG levels between four neck pain disability subgroups (analysis of variance reaching P-levels of 0.000), with an inverse relationship between the level of neck pain disability and EMG level. Furthermore, follow-up assessments of the EMG level during these two tasks, did not show a time related change. In conclusion, in subjects with future disability, the acute stage is characterized by a reorganization of the muscular activation of neck and shoulder muscles, possibly aimed at minimizing the use of painful muscles. This change of motor control, is in

  13. Iliac Artery and Vein Injury Without Pelvic Fracture Due To Blunt Trauma: A Rare Case

    Full Text Available Iliac vascular injuries have high morbidity and mortality rates. Penetrant abdominal and pelvic vascular injuries are more common compared to blunt traumas. Pelvic vascular injuries associated with blunt trauma are quite likely to occur in accompaniment with pelvic fracture. A 23 year old male patient was admitted to the emergency room due to a motorcycle accident. Shock picture was prevalent in the patient. Shaft fracture was present in left femur and flow was not detected in arterial and venous colour Doppler ultrasonography. Patient underwent emergency surgery. Left main iliac artery and vein were normal, however, external iliac vein was lacerated in two spots, and blood vessel wall integrity was damaged in one part of left external iliac artery. Clinical presentation and traumatic retroperitoneal hematoma management of iliac artery and venous injuries due to blunt trauma without pelvic fracture are discussed in the presented case.

    Penetrating landmine injuries are the unavoidable consequences of military conflicts. They are potentially life-threatening. The mortality rates in the literature range from 23% to 92% and are considerably higher in patients admitted with poor neurologic state. Penetrating craniocerebral injuries require early surgical management designated to prevent infection and remove foreign objects, necrotic tissue and complicating blood clots, as well as to minimalize post-traumatic sequelae. We report herein an interesting case of penetrating intracerebral injury with giant shrapnel due to landmine in a 20-year-old young man.

    The present study was designed to elucidate the outcome of subchronic co-administration of black tea and nicotine on cardiovascular performance and whether these substances could modulate the isoproterenol-induced cardiac injury. Animal groups were control, black tea, nicotine and black tea plus nicotine. Test groups received nicotine (2 mg/kg s.c.) and black tea brewed (p.o.) each alone and in combination for 4 weeks. On the 28th day, myocardial damage was induced by isoproterenol (50 mg/kg i.p.), and blood samples were taken. On day 29, after hemodynamic parameters recording, hearts were removed for histopathological evaluation. Tea or nicotine consumption had no significant effects on hemodynamic indices of animals without heart damage. When the cardiac injury was induced, tea consumption maintained the maximum dp/dt, and nicotine significantly decreased the pressure-rate product. Moreover, severity of heart lesions was lower in the presence of nicotine or black tea. Concomitant use of these materials did not show extra effects on mentioned parameters more than the effect of each of them alone. The results suggest that subchronic administration of black tea or nicotine for a period of 4 weeks may have a mild cardioprotective effect, while concomitant use of these materials cannot intensify this beneficial effect.

  17. Nitric Oxide as a Mediator of Oxidant Lung Injury Due to Paraquat

    At low concentrations, nitric oxide is a physiological transmitter, but in excessive concentrations it may cause cell and tissue injury. We report that in acute oxidant injury induced by the herbicide paraquat in isolated guinea pig lungs, nitric oxide synthesis was markedly stimulated, as evidenced by increased levels of cyclic GMP in lung perfusate and of nitrite and L-citrulline production in lung tissue. All signs of injury, including increased airway and perfusion pressures, pulmonary edema, and protein leakage into the airspaces, were dose-dependently attenuated or totally prevented by either N^G-nitro-L-arginine methyl ester or N^ω-nitro-L-arginine, selective and competitive inhibitors of nitric oxide synthase. Protection was reversed by excess L-arginine but not by its enantiomer D-arginine. When blood was added to the lung perfusate, the paraquat injury was moderated or delayed as it was when paraquat was given to anesthetized guinea pigs. The rapid onset of injury and its failure to occur in the absence of Ca2+ suggest that constitutive rather than inducible nitric oxide synthase was responsible for the stimulated nitric oxide synthesis. The findings indicate that nitric oxide plays a critical role in the production of lung tissue injury due to paraquat, and it may be a pathogenetic factor in other forms of oxidant tissue injury.

    Personality change due to traumatic brain injury (PC) in children is an important psychiatric complication of injury and is a form of severe affective dysregulation. This study aimed to examine neurocognitive correlates of PC. The sample included 177 children 5-14 years old with traumatic brain injury who were enrolled from consecutive admissions to five trauma centers. Patients were followed up prospectively at baseline and at 6 months, and they were assessed with semistructured psychiatric interviews. Injury severity, socioeconomic status, and neurocognitive function (measures of attention, processing speed, verbal memory, IQ, verbal working memory, executive function, naming/reading, expressive language, motor speed, and motor inhibition) were assessed with standardized instruments. Unremitted PC was present in 26 (18%) of 141 participants assessed at 6 months postinjury. Attention, processing speed, verbal memory, IQ, and executive function were significantly associated with PC even after socioeconomic status, injury severity, and preinjury attention deficit hyperactivity disorder were controlled. These findings are a first step in characterizing concomitant cognitive impairments associated with PC. The results have implications beyond brain injury to potentially elucidate the neurocognitive symptom complex associated with mood instability regardless of etiology.

    The goal of this study was to identify an injectable anesthetic protocol that provides sedation sufficient for peripheral vascular catheterization, intubation, and transport while minimizing cardiovascular changes in Yorkshire and Yucatan pigs with and without cardiovascular injury and intervention (CI). Phase 1 examined the safety and efficacy of acepromazine-ketamine, diazepam-ketamine, midazolam-ketamine, and medetomidine-ketamine in 5 healthy Yorkshire pigs. For each drug combination, we obtained multiple measurements of heart rate, blood pressure, respiratory rate, temperature, sedation score, ability to catheterize and intubate, and recovery score. Phase 2 evaluated and refined the dose of the most effective Phase 1 anesthetic combination (midazolam-ketamine) in healthy and CI Yorkshire pigs (n = 53 trials). Phase 3 mirrored Phase 2 but tested midazolam-ketamine in healthy and CI Yucatan pigs (n = 34 trials). Midazolam (0.5 mg/kg)-ketamine (25 to 27 mg/kg) was the most effective anesthetic combination in healthy Yorkshire pigs, but this dose was less effective in healthy Yucatan pigs and CI Yorkshire and Yucatan pigs. Midazolam-ketamine resulted in tachycardia and apnea more frequently in CI pigs than healthy pigs. This combination also caused vomiting in one CI Yucatan pig. Overall, midazolam-ketamine provided safe and effective sedation for catheterization and intubation of both healthy and CI pigs. This study suggests Yucatan pigs may require a higher dose midazolam-ketamine to achieve the same level of sedation as that in Yorkshire pigs. Although anesthetic complication rates were higher in CI pigs, our results indicate that midazolam-ketamine can be safely used for sedation of both pig breeds with and without CI.

    Social inequalities in cardiovascular disease mortality are described in this paper focusing on the results of the Studio Longitudinale Torinese (SLT), an investigation that links census data with the statistical data that are currently available. The overall results confirm that cardiovascular disease mortality is higher in less-advantaged socioeconomic groups, irrespectively of the social indicator used: education, social class, housing quality, job security. Stratified data shows less important inequalities among ischemic heart disease as compared to cerebrovascular mortality. The differences are even more complex when the age groups in the two genders are analyzed, revealing cohort effects. Overall, the results agree with the previous survey carried out by ISTAT on 1981 Italian mortality, which confirmed the variations in inequalities according to geographical areas, gender and age. Differences in access to the health system are likely to be related to the differences detected for geographical areas, while differences in personal history and attitude towards health-associated behavior should explain age and gender variations in inequalities. Equity must be included in the evaluation of preventive programs and health-care models. Epidemiological and social research should be encouraged to better understand the factors that influence inequalities in cardiovascular disease mortality and in the health status of the population at large.

    Cardiovascular (CV) issues after spinal cord injury (SCI) are of paramount importance considering they are the leading cause of death in this population. Disruption of autonomic pathways leads to a highly unstable CV system, with impaired blood pressure (BP) and heart rate regulation. In addition to low resting BP, on a daily basis the majority of those with SCI suffer from transient episodes of aberrantly low and high BP (termed orthostatic hypotension and autonomic dysreflexia, respectively). In fact, autonomic issues, including resolution of autonomic dysreflexia, are frequently ranked by individuals with high-level SCI to be of greater priority than walking again. Owing to a combination of these autonomic disturbances and a myriad of lifestyle factors, the pernicious process of CV disease is accelerated post-SCI. Unfortunately, these secondary consequences of SCI are only beginning to receive appropriate clinical attention. Immediately after high-level SCI, major CV abnormalities present in the form of neurogenic shock. After subsiding, new issues related to BP instability arise, including orthostatic hypotension and autonomic dysreflexia. This review describes autonomic control over the CV system before injury and the mechanisms underlying CV abnormalities post-SCI, while also detailing the end-organ consequences, including those of the heart, as well as the systemic and cerebral vasculature. The tertiary impact of CV dysfunction will also be discussed, such as the potential impediment of rehabilitation, and impaired cognitive function. In the recent past, our understanding of autonomic dysfunctions post-SCI has been greatly enhanced; however, it is vital to further develop our understanding of the long-term consequences of these conditions, which will equip us to better manage CV disease morbidity and mortality in this population.

    Synoptic weather and ambient air quality synergistically influence human health. We report the relative risk of mortality from all non-accidental, respiratory-, and cardiovascular-related causes, associated with exposure to four air pollutants, by weather type and season, in 10 major Canadian cities for 1981 through 1999. We conducted this multi-city time-series study using Poisson generalized linear models stratified by season and each of six distinctive synoptic weather types. Statistically significant relationships of mortality due to short-term exposure to carbon monoxide, nitrogen dioxide, sulphur dioxide, and ozone were found, with significant modifications of risk by weather type, season, and mortality cause. In total, 61% of the respiratory-related mortality relative risk estimates were significantly higher than for cardiovascular-related mortality. The combined effect of weather and air pollution is greatest when tropical-type weather is present in the spring or summer.

  11. Levosimendan: a cardiovascular drug to prevent liver ischemia-reperfusion injury?

    Directory of Open Access Journals (Sweden)

    Peter Onody

    Full Text Available INTRODUCTION: Temporary occlusion of the hepatoduodenal ligament leads to an ischemic-reperfusion (IR injury in the liver. Levosimendan is a new positive inotropic drug, which induces preconditioning-like adaptive mechanisms due to opening of mitochondrial KATP channels. The aim of this study was to examine possible protective effects of levosimendan in a rat model of hepatic IR injury. MATERIAL AND METHODS: Levosimendan was administered to male Wistar rats 1 hour (early pretreatment or 24 hours (late pretreatment before induction of 60-minute segmental liver ischemia. Microcirculation of the liver was monitored by laser Doppler flowmeter. After 24 hours of reperfusion, liver and blood samples were taken for histology, immuno- and enzyme-histochemistry (TUNEL; PARP; NADH-TR as well as for laboratory tests. Furthermore, liver antioxidant status was assessed and HSP72 expression was measured. RESULTS: In both groups pretreated with levosimendan, significantly better hepatic microcirculation was observed compared to respective IR control groups. Similarly, histological damage was also reduced after levosimendan administration. This observation was supported by significantly lower activities of serum ALT (p early = 0.02; p late = 0.005, AST (p early = 0.02; p late = 0.004 and less DNA damage by TUNEL test (p early = 0.05; p late = 0.034 and PAR positivity (p early = 0.02; p late = 0.04. Levosimendan pretreatment resulted in significant improvement of liver redox homeostasis. Further, significantly better mitochondrial function was detected in animals receiving late pretreatment. Finally, HSP72 expression was increased by IR injury, but it was not affected by levosimendan pretreatment. CONCLUSION: Levosimendan pretreatment can be hepatoprotective and it could be useful before extensive liver resection.

    Hydrofluoric acid, a highly dangerous substance, can cause tissue damage and systemic toxicity by its unique mechanisms. Many cases of severe faciocervical burns due to hydrofluoric acid exposure are lethal. Herein, we present a case of 37-year-old man who suffered from hydrofluoric acid burns to his face, anterior neck, lips, and nasal cavity. On admission, this patient coughed with much sputum, and the chest auscultation detected rough breath sounds, wheezes, and very weak heart sounds, indicating possible inhalation injury. This case highlights the extreme complexity of managing this kind of injury. Timely and accurate wound treatment and respiratory tract care, as well as active systematic support treatment, played vital roles in the management of this patient.

    Postoperative respiratory insufficiency is a serious complication of total thyroidectomies which can be multifactorial, especially in children. We report two siblings who had undergone thyroidectomy with subsequent respiratory distress. Electrothermal bipolar and harmonic scalpel were used during thyroid dissections. Both patients had early postoperative respiratory problems. The older one suffered from mild respiratory distress for 24 hours and then he spontaneously recovered. The younger one was extubated but then she had serious stridor accompanied with abdominal and intercostal retractions. She was re-intubated and admitted to ICU for mechanical ventilatory support, where she stayed for 14 days due to multiple failed extubation attempts. The symptoms were more severe in the younger child probably due to softer tracheal wall and weaker tracheal cartilages. We should keep in mind the probable postoperative respiratory complications due to thermal injury or inappropriate surgical technique after thyroid surgeries.

    Developed and approved a pathogenic grounded experimental model of brain condition during cardiovascular bypass surgery. Undertaken in Wistar rats research allowed to evaluate in detail effectiveness and safety of protracted cerebroprotective treatment. Advantages of this model are researches in laboratory animals with the aim to research condition of nerve tissue, not intensive procedures and consequently high reproducibility and possibility of complex evaluation of changes at every stage of research. Results of neurons, neuroglia and activation of neurotrophic mechanisms prove that simulation of brain condition during cardiovascular bypass surgery is accompanied with acute and delayed brain injuries. Use of Cytoflavin under pharmalogic cerebroprotection had prolonged multimodal and neuroprotactive effect, leading to improvement of neurotrophic protection from the first days.

    2013-11-01

    A 23-year-old man presented with abdominal pain after suffering blunt trauma caused by a seatbelt injury. His low platelet count of 137 × 10(9)/L was initially attributed to trauma and his underlying hypersplenism due to glucose-6-phosphate dehydrogenase (G6PD) deficiency. Despite conservative management, his platelet count remained persistently reduced even after his haemoglobin and clotting abnormalities were stabilised. After a week, follow-up imaging revealed an incidental finding of a pseudoaneurysm (measuring 9 mm × 8 mm × 10 mm) adjacent to a splenic laceration. The pseudoaneurysm was successfully closed via transcatheter glue embolisation; 20% of the spleen was also embolised. A week later, the platelet count normalised, and the patient was subsequently discharged. This case highlights the pitfalls in the detection of a delayed occurrence of splenic artery pseudoaneurysm after blunt injury via routine delayed phase computed tomography. While splenomegaly in G6PD may be a predisposing factor for injury, a low platelet count should arouse suspicion of internal haemorrhage rather than hypersplenism.

    One hundred and fifty bicycle accidents seen at the Children's Hospital Sheffield over a 6-month period from mid-August 1979 were analysed and 9.3 per cent of the cases were admitted. Twenty-two per cent had fractures, 20 per cent had soft tissue injuries of face or scalp, 8 children having damaged their teeth. Of the accidents 17.3 per cent were due to hitting an obstruction, 30.7 per cent were due to loss of control on a hill or corner and 8 per cent were of mechanical origin. Eighty-eight per cent had cycling experience of a year or more, and 32.7 per cent had had previous cycling accidents. Comparison with other types of accidents previously studied at the hospital, involving skateboards, playground equipment or road traffic accidents affecting child pedestrians, showed that by far the most serious were those involving child pedestrians. The injuries from bicycle accidents were similar in severity to those involving skateboards.

    Full Text Available No systematic review has been published on the use of acupuncture for the treatment of chronic urinary retention (CUR due to spinal cord injury (SCI. The aim of this review was to assess the effectiveness and safety of acupuncture for CUR due to SCI. Three randomized controlled trials (RCTs including 334 patients with CUR due to SCI were included. Meta-analysis showed that acupuncture plus rehabilitation training was much better than rehabilitation training alone in decreasing postvoid residual (PVR urine volume (MD −109.44, 95% CI −156.53 to −62.35. Likewise, a combination of acupuncture and aseptic intermittent catheterization was better than aseptic intermittent catheterization alone in improving response rates (RR 1.23, 95% CI 1.10 to 1.38. No severe adverse events were reported. In conclusion, acupuncture as a complementary therapy may have a potential effect in CUR due to SCI in decreasing PVR and improving bladder voiding. Additionally, acupuncture may be safe in treating CUR caused by SCI. However, due to the lack of high quality RCTs, we could not draw any definitive conclusions. More well-designed RCTs are needed to provide strong evidence.

    deflection was determined from motion capture video of the impact test. HIC- 15 and BRIC were calculated from head acceleration responses. Given the number of human subjects for each test condition a confidence interval of injury probability will be obtained. RESULTS: Results will be discussed in terms of injury-risk probability estimates based on the human data set evaluated. Also, gaps in the data set will be identified. These gaps could be one of two types. One is areas where additional THOR testing would increase the comparable human data set, thereby improving confidence in the injury probability rate. The other is where additional human testing would assist in obtaining information on other acceleration levels or directions. DISCUSSION: The historical human data showed validity of the THOR ATD for supplemental testing. The historical human data are limited in scope, however. Further data are needed to characterize the effects of sex, age, anthropometry, and deconditioning due to spaceflight on risk of injury

    Full Text Available Background: Rubber bullets and pellet guns are considered non-lethal low-velocity weapons. They are used to disperse a mob during street protests. The present study was undertaken to analyze the pattern, presentation and management of vascular injuries caused by these weapons. Patients and Methods: This was a prospective study of patients with features of vascular injuries due to pellets and rubber bullets from June 2010 to November 2010. All patients with features of vascular injuries due to these non-lethal weapons were included in the study. Vascular injuries caused by other causes were excluded from the study. Results: A total of 35 patients who presented with features of vascular injury during this period were studied. All of them were males. The mean age was 22 years. Fifteen patients were revascularized primarily, 19 patients needed reverse saphenous vein graft and, in one, patient lateral repair was done. There were two mortalities in our series. Wound infection was the most common complication. The amputation rate was around 6%. Conclusion: Pellet and rubber bullets can cause serious life-threatening injuries. Vascular injury caused by these weapons need no different approach than other vascular injuries. Early revascularization and prompt resuscitation prevents the loss of limb or life.

    Background: Studies have shown different mortalities due to cardiovascular diseases (CVD), ischemic heart disease (IHD) and cerebrovascular diseases (CbVD) in the five Brazilian regions. Socioeconomic conditions of those regions are frequently used to justify differences in mortality due to those diseases. In addition, studies have shown a reduction in the differences between the mortality rates of the five Brazilian regions. Objective: To update CVD mortality data in women and men in the five Brazilian regions. Methods: Mortality and population data were obtained from the Brazilian Institute of Geography and Statistics and Ministry of Health. Risk of death was adjusted by use of the direct method, with the 2000 world standard population as reference. We analyzed trends in mortality due to CVD, IHD and CbVD in women and men aged ≥ 30 years in the five Brazilian regions from 1980 to 2012. Results: Mortality due to: 1) CVD: showed reduction in the Northern, West-Central, Southern and Southeastern regions; increase in the Northeastern region; 2) IHD: reduction in the Southeastern and Southern regions; increase in the Northeastern region; and unchanged in the Northern and West-Central regions; 3) CbVD: reduction in the Southern, Southeastern and West-Central regions; increase in the Northeastern region; and unchanged in Northern region. There was also a convergence in mortality trends due to CVD, IHD, and CbVD in the five regions. Conclusion: The West-Central, Northern and Northeastern regions had the worst trends in CVD mortality as compared to the Southeastern and Southern regions.

    A case of skin injuries due to stings by crown-of-thorns starfish, Acanthaster planci, in a 53-year-old Okinawan woman is reported. She went to a beach to gather shellfish on 8 April 2001 and fell to the ground with her left palm on a crown-of-thorns starfish that happened to be close to her. She hurried to the emergency section of our hospital. An emergency doctor sterilized the wound and administered an antibiotic, an analgesic agent and an injection of a tetanus antitoxin. He tried to remove the remaining spines from the palm with great difficulty. Because swelling and subcutaneous indurations of the left palm had persisted thereafter, oral and topical administration of corticosteroid started on 13 April. Physical examination at the dermatology section revealed approximately 10 stab wounds of the left palm with pus, subcutaneous bleeding and many abrasions around them. X-rays of the left hand showed foreign bodies, 2-10 mm in size, located on the lesions. The patient was treated with a topical injection of 2 mg triamcinolone acetonide (Kenacort-A), diluted fivefold with 1% Xylocaine, once a week. Some of the foreign body granulomatous lesions improved but pain and subcutaneous indurations persisted in most of the lesions. Because the X-ray photographs showed many remaining spines, surgical excision to remove them was performed under local anesthesia 3 months after the injury. All the symptoms improved after the operation. Scanning electron microscopic examination of the spines revealed that their tips had fragile lattice-like structures.

    The South African Government recently set targets to reduce cardiovascular disease (CVD) by lowering salt consumption. We conducted an extended cost-effectiveness analysis (ECEA) to model the potential health and economic impacts of this salt policy. We used surveys and epidemiologic studies to estimate reductions in CVD resulting from lower salt intake. We calculated the average out-of-pocket (OOP) cost of CVD care, using facility fee schedules and drug prices. We estimated the reduction in OOP expenditures and government subsidies due to the policy. We estimated public and private sector costs of policy implementation. We estimated financial risk protection (FRP) from the policy as (1) cases of catastrophic health expenditure (CHE) averted or (2) cases of poverty averted. We also performed a sensitivity analysis. We found that the salt policy could reduce CVD deaths by 11%, with similar health gains across income quintiles. The policy could save households US$ 4.06 million (2012) in OOP expenditures (US$ 0.29 per capita) and save the government US$ 51.25 million in healthcare subsidies (US$ 2.52 per capita) each year. The cost to the government would be only US$ 0.01 per capita; hence, the policy would be cost saving. If the private sector food reformulation costs were passed on to consumers, food expenditures would increase by salt reduction can have positive economic impacts-substantially reducing OOP expenditures and providing FRP, particularly for the middle class. The policy could also provide large government savings on health care.

    Shark attacks on humans might not occur as often as is believed and the characteristic features of shark injuries on corpses have not been extensively reviewed. We describe the characteristic features of shark injuries on 12 corpses. The analysis of these injuries might reveal the motivation behind the attacks and/or the shark species involved in the attack. Gouge marks on the bones are evidence of a shark attack, even if the corpse is decomposed. Severance of the body part at the joints without a fracture was found to be a characteristic feature of shark injuries.

    Full Text Available Lasers have been used in the management of benign prostatic hyperplasia for the last two decades. To be comparable, they should reduce or avoid the immediate and long-term complications of transurethral resection of the prostate (TURP or open prostatectomy (OP, especially bleeding and need for blood transfusion. Although Holmium laser treatment of the prostate was compared frequently in terms of cardiovascular safety with TURP or OP, photoselective vaporisation of the prostate (PVP was not largely evaluated. In this article we analyzed the current literature to see if there is convincing data to support the observation of some authors that use of PVP is associated with increased safety in patients on anticoagulants with cardiovascular comorbidities. With this purpose a Medline search between January 2004 to March 2013 was performed using evidence obtained from randomised trials, well-designed controlled studies without randomisation, individual cohort studies, individual case control studies and case reports Results: In the last 10 years, several case-control and cohort studies have demonstrated the efficacy of PVP as well as its safety in patients with cardiovascular comorbidities using anticoagulants. The results confirmed the overall lower perioperative and postoperative morbidity of PVP, whereas the efficacy was comparable to TURP in the short term, despite a higher reoperation rate. Conclusion: Although it is still developing, PVP with KTP or LBO seems to be a promising alternative to both TURP and OP in terms of cardiovascular safety and in patients using anticoagulants.

    Full Text Available Radial nerve damage is frequently encountered in humeral fractures. The radial nerve is primarily damaged when the humerus gets fractured, while secondary damage maybe due to post-traumatic manipulations and surgical exploration. High impact traumatic nerve injury, serious neuropathic pain, lack of response to therapeutic interventions, and indifference to the Tinel test are indications for surgical intervention. Since most humeral fracture-induced low impact radial nerve injuries resolve spontaneously, conservative therapy is preferred. We present a patient with humeral fracture-associated radial nerve injury, accompanied with digital amputation and flexor tendon avulsion on the same arm. These injuries required immediate surgery, thus rendering the clinical evaluation of the radial nerve impossible. We would like to highlight and discuss the inherent difficulties associated with multiple trauma of the upper arm.

    As a consequence of the novel therapeutic option of mechanical ventilation in early intensive care medicine, the acute respiratory distress syndrome (ARDS) was defined as a disease entity of its own representing the most severe form of acute lung injury (ALI). Since its first description four decades ago, our knowledge about the aetiology, physiology, histology and epidemiology of this lethal pulmonary complication of severe acute diseases such as pneumonia or sepsis has been increasing steadily. The initial major therapeutic advances were due to improvements in intensive care medical procedures and monitoring. The large ARDS Network clinical trial on the magnitude of tidal volume impressively demonstrated the feasibility of targeted clinical trials in patients with ARDS that provide robust evidence in this field. This clinical trial, as well as following large-scale trials in ARDS patients, led to significant changes of ventilation therapy and therapeutic strategies that improve the outcome of this disease entity. Advances in the standardisation of care for ARDS patients involving innovative therapeutic procedures such as extracorporeal gas exchange systems will lead to a further improvement in ARDS management and outcome. Modern pulmonary medicine can play a pivotal role in this process and can contribute its rich experiences in all areas of the respiratory system.

  13. Paraquat poisoning: an experimental model of dose-dependent acute lung injury due to surfactant dysfunction

    Full Text Available Since the most characteristic feature of paraquat poisoning is lung damage, a prospective controlled study was performed on excised rat lungs in order to estimate the intensity of lesion after different doses. Twenty-five male, 2-3-month-old non-SPF Wistar rats, divided into 5 groups, received paraquat dichloride in a single intraperitoneal injection (0, 1, 5, 25, or 50 mg/kg body weight 24 h before the experiment. Static pressure-volume (PV curves were performed in air- and saline-filled lungs; an estimator of surface tension and tissue works was computed by integrating the area of both curves and reported as work/ml of volume displacement. Paraquat induced a dose-dependent increase of inspiratory surface tension work that reached a significant two-fold order of magnitude for 25 and 50 mg/kg body weight (P<0.05, ANOVA, sparing lung tissue. This kind of lesion was probably due to functional abnormalities of the surfactant system, as was shown by the increase in the hysteresis of the paraquat groups at the highest doses. Hence, paraquat poisoning provides a suitable model of acute lung injury with alveolar instability that can be easily used in experimental protocols of mechanical ventilation

    The tonic stretch reflex elicited by vibration of a muscle or tendon provides a means of studying segmental reflex activity in humans with impaired volitional motor activity due to spinal cord injury (SCI). Vibration applied to the achilles or patellar tendon in a group of 51 SCI subjects elicited motor unit activity different from that found in 12 healthy subjects. Four distinct features of motor unit responses to vibration of a single tendon (achilles or patellar) could be seen in the SCI subjects: (i) a rapid onset, tonic response, frequently beginning with a single burst analogous to a tendon jerk, in 72% of vibrated sites; (ii) repetitive, phasic bursts of activity or vibratory-induced clonus in 23% of the tonic responses; (iii) spread of activity to muscles distant from the vibration in 44% of the tonic responses; and vibratory-induced withdrawal reflexes (VWR) which occurred after vibration of 37% of the sites. Overall, 81% of stimulated sites responded to vibration in SCI subjects. In contrast, only 54% of vibrated sites responded in control subjects, always with a gradual onset tonic response, never accompanied by a VWR. The VWR in SCI subjects was typically of much larger amplitude than the tonic responses and involved a mean of 5 muscles (41% bilaterally). Features of these responses provide an insight into underlying neurocontrol mechanisms which may provide guidance in the selection of appropriate intervention or management strategies.

  15. A Thoracic Mechanism of Mild Traumatic Brain Injury Due to Blast Pressure Waves

    Courtney, Amy; 10.1016/j.mehy.2008.08.015

    2008-01-01

    The mechanisms by which blast pressure waves cause mild to moderate traumatic brain injury (mTBI) are an open question. Possibilities include acceleration of the head, direct passage of the blast wave via the cranium, and propagation of the blast wave to the brain via a thoracic mechanism. The hypothesis that the blast pressure wave reaches the brain via a thoracic mechanism is considered in light of ballistic and blast pressure wave research. Ballistic pressure waves, caused by penetrating ballistic projectiles or ballistic impacts to body armor, can only reach the brain via an internal mechanism and have been shown to cause cerebral effects. Similar effects have been documented when a blast pressure wave has been applied to the whole body or focused on the thorax in animal models. While vagotomy reduces apnea and bradycardia due to ballistic or blast pressure waves, it does not eliminate neural damage in the brain, suggesting that the pressure wave directly affects the brain cells via a thoracic mechanism. ...

    A 75-year-old man referred to the outpatient vascular surgery clinic of Taleghani Hospital (Shaheed Beheshti University of Medicine, Tehran, Iran) due to a local nontender mass in his groin. In his history, it was discovered that the mass had appeared a few months after a gunshot injury. He had a history of shortness of breath with a New York Heart Association functional class fluctuating between II and III, but no history of smoking or addiction. In the physical examination, a 5-cm by 5-cm nonpulsatile mass with engorged vessels was found in the anterior portion of the left groin, which was not tender. An elective arterial angiography revealed an arteriovenous fistula joining the femoral artery to the femoral vein at the left groin. The cardiac assessments revealed cor pulmonale (with a restrictive pattern and diastolic dysfunction) and pulmonary hypertension due to primary pulmonary dysfunction. The patient was anesthetized with a balanced general anesthesia method, considering all relevant cardiac and respiratory monitoring methods and specially withholding drugs increasing pulmonary vascular bed pressure, suppressing the myocardium, or increasing the regurgitant flow across the mitral and, especially, the tricuspid valve. The moment the fistula was closed, a rapid fall in the patient's heart rate was noted, from approximately 60 beats per minute to above 40 beats per minute; this decreased heart rate continued up to a few hours after the surgery and did not accompany any significant hemodynamic derangement including the patient's blood pressure. The patient received his postoperative care in the ordinary surgical ward and was discharged a few days later.

  17. Relationship between Spinal Cord Volume and Spinal Cord Injury due to Spinal Shortening.

    Full Text Available Vertebral column resection is associated with a risk of spinal cord injury. In the present study, using a goat model, we aimed to investigate the relationship between changes in spinal cord volume and spinal cord injury due to spinal shortening, and to quantify the spinal cord volume per 1-mm height in order to clarify a safe limit for shortening. Vertebral column resection was performed at T10 in 10 goats. The spinal cord was shortened until the somatosensory-evoked potential was decreased by 50% from the baseline amplitude or delayed by 10% relative to the baseline peak latency. A wake-up test was performed, and the goats were observed for two days postoperatively. Magnetic resonance imaging was used to measure the spinal cord volume, T10 height, disc height, osteotomy segment height, and spinal segment height pre- and postoperatively. Two of the 10 goats were excluded, and hence, only data from eight goats were analyzed. The somatosensory-evoked potential of these eight goats demonstrated meaningful changes. With regard to neurologic function, five and three goats were classified as Tarlov grades 5 and 4 at two days postoperatively. The mean shortening distance was 23.6 ± 1.51 mm, which correlated with the d-value (post-pre of the spinal cord volume per 1-mm height of the osteotomy segment (r = 0.95, p < 0.001 and with the height of the T10 body (r = 0.79, p = 0.02. The mean d-value (post-pre of the spinal cord volume per 1-mm height of the osteotomy segment was 142.87 ± 0.59 mm3 (range, 142.19-143.67 mm3. The limit for shortening was approximately 106% of the vertebral height. The mean volumes of the osteotomy and spinal segments did not significantly change after surgery (t = 0.310, p = 0.765 and t = 1.241, p = 0.255, respectively. Thus, our results indicate that the safe limit for shortening can be calculated using the change in spinal cord volume per 1-mm height.

    Full Text Available Abstract Background In November 2008, a surgical team from the Red Cross Hospital Beverwijk, the Netherlands, was deployed in Afghanistan for three months to attend in the army hospital of Kandahar. During their stay, four incidents of armored personnel carriers encountering an improvised explosive device were assessed. In each incident, two soldiers were involved, whose injuries were strikingly similar. Case presentation The described cases comprise paired thoracic vertebral fractures, radial neck fractures, calcaneal fractures and talar fractures. Moreover, the different types of blast injury are mentioned and related to the injuries described in our series. Acknowledging the different blast mechanisms is important for understanding possible injury patterns. Conclusion From this case series, as well as the existing literature on injury patterns caused by blast injuries, it seems appropriate to pay extra attention to bodily areas that were injured in other occupants of the same vehicle. Obviously, the additional surveillance for specific injuries should be complementary to the regular trauma work-up (e.g., ATLS.

    An association between closed posterior elbow dislocation and traumatic brachial artery injury is rare. Absence of radial pulse on palpation is an important warning sign and arteriography is the gold-standard diagnostic test. Early diagnosis is essential for appropriate treatment to be provided. This consists of joint reduction and immobilization, along with urgent surgical restoration of arterial flow. Here, a case (novel to the Brazilian literature) of an association between these injuries (and the treatment implemented) in a 27-year-old male patient is reported. These injuries were sustained through physical assault. PMID:27069896

    Full Text Available Abstract Background Malnutrition and inflammation are common and serious complications in patients with acute kidney injury (AKI. However, the profile of these complications in patients with AKI caused by crush syndrome (CS remains unclear. This study describes the clinical characteristics of malnutrition and inflammation in patients with AKI and CS due to the Wenchuan earthquake. Methods One thousand and twelve victims and eighteen healthy adults were recruited to the study. They were divided into five groups: Group A was composed of victims without CS and AKI (904 cases; Group B was composed of patients with CS and AKI who haven't received renal replacement therapy (RRT (57 cases; and Group C was composed of patients with CS and AKI receiving RRT (25 cases; Group D was composed of earthquake victims with AKI but without CS (26 cases; and Group E was composed of 18 healthy adult controls. The C-reactive protein (CRP, prealbumin, transferrin, interleukin-6 and TNF-α were measured and compared between Group E and 18 patients from Group C. Results The results indicate that participants in Group C had the highest level of serum creatinine, blood urea nitrogen and uric acid. Approximately 92% of patients with CS who had RRT were suffering from hypoalbuminemia. The interleukin-6 and CRP levels were significantly higher in patients with CS AKI receiving RRT than in the control group. Patients in Group C received the highest dosages of albumin, plasma or red blood cell transfusions. One patient in Group C died during treatment. Conclusions Malnutrition and inflammation was common in patients with earthquake-related CS and had a negative impact on the prognosis of these subjects. The results of this study indicate that the use of RRT, intensive nutritional supplementation and transfusion alleviated the degree of malnutrition and inflammation in hemodialysis patients with crush syndrome.

    Obesity is an important identifier of cardiovascular disease (CVD) risk, but is challenging to determine accurately in individuals with spinal cord injury (SCI). Body mass index (BMI) is used worldwide as a simple indicator of obesity, but is difficult to measure in individuals with SCI. Furthermore, standard BMI cutoffs underestimate obesity in this population. Therefore, we aimed to identify the best marker of obesity in individuals with SCI, considering both practicality, and ability to detect adiposity and CVD risk. Five anthropometric measures were evaluated: BMI; waist circumference (WC); waist-to-height ratio (WHtR); waist-to-hip ratio; and neck circumference. We evaluated relationships between these measures and abdominal and total body-fat percentage, seven cardiovascular metabolic risk factors (fasting insulin, glucose, glucose tolerance, triglycerides, high-density lipoprotein, low-density lipoprotein, and total cholesterol), and the Framingham risk score. BMI, WC, and WHtR were correlated with abdominal fat percentage. WC and WHtR were correlated with five metabolic risk factors as well as the Framingham risk score. WC is a more practical measure for an SCI population. The optimal cutoff for identifying adverse CVD risk in individuals with SCI was identified as WC ≥94 cm, with 100% sensitivity and 79% specificity. We propose that WC is a simple, more sensitive alternative to BMI in this population that is easy to use in multiple settings. The cutoff provides a simple tool to predict adverse CVD risk profiles that can be used to guide risk management, as well as as a practical aid for individuals with SCI to maintain a healthy body composition.

    Full Text Available Abstract Introduction Axillary artery injury in the shoulder region following blunt trauma without association with either shoulder dislocation or fracture of the humeral neck has been previously reported. Axillary artery injury might also be accompanied with brachial plexus injury. However, delayed onset of brachial plexus palsy caused by a compressive hematoma associated with axillary injury after blunt trauma in the shoulder region has been rarely reported. In previous reports, this condition only occurred in old patients with sclerotic vessels. We present a case of a young patient who suffered axillary artery injury associated with brachial plexus palsy that occurred tardily due to compressive hematoma after blunt trauma in the shoulder region without association of either shoulder dislocation or humeral neck fracture. Case presentation A 16-year-old male injured his right shoulder in a motorbike accident. On initial physical evaluation, the pulses on the radial and ulnar arteries in the affected arm were palpable. Paralysis developed later from 2 days after the injury. Functions in the right arm became significantly impaired. Angiography showed complete occlusion of the axillary artery. Magnetic resonance imaging demonstrated a mass measuring 4 × 5 cm that was suspected to be a hematoma compressing the brachial plexus in a space between the subscapular muscle and the pectoralis minor muscle. Surgery was performed on the third day after injury. In intraoperative observations, the axillary artery was occluded with thrombus along 5 cm; a subscapular artery was ruptured; the brachial plexus was compressed by the hematoma. After evacuation of the hematoma, neurolysis of the brachial plexus, and revascularization of the axillary artery, the patient had an excellent functional recovery of the affected upper limb, postoperatively. Conclusion Surgeons should be aware that axillary artery injuries may even occur in young people after severe blunt

    Full Text Available Objectives: In several epidemiological studies of maxillofacial trauma, falls were one of the most frequent causes of facial injury. The aim of this study is to analyse the patterns of fall-related maxillofacial injuries based on the height of the fall. Material and Methods: Using a systematic computer-assisted database of patients hospitalised with maxillofacial fractures, only those with fall-related injuries were considered. The falls were divided into four groups: falls from slipping, tripping or stumbling (STSF, loss of consciousness (LOCF, stairs (SAF, and height (HF. Data on the age, gender, fracture site, Facial Injury Severity Scale (FISS, facial lacerations, associated lesions, type of treatment, and length of hospital stay were also analysed. Results: This study included 557 patients (338 males, 219 females; average age 51.5 years [range 4 - 99 years]. In the over 60 age group, females were more prevalent in STSF than males. According to aetiology, STSF was the most frequent cause of maxillofacial fractures (315 patients; 56.5% followed by LOCF (157; 28.2%, HF (55; 9.9%, and SAF (30; 5.4%. The middle third of the face was affected most frequently. After LOCF, however, the inferior third was prevalently involved. The majority of associated fractures, as well as the most severe injuries and greatest rate of facial lacerations, occurred secondary to HF. Conclusions: This study showed that fracture severity and site are influenced not only by patient age, but also by the nature of the fall.

    OBJECT Nonpowder guns, defined as spring- or gas-powered BB or pellet guns, can be dangerous weapons that are often marketed to children. In recent decades, advances in compressed-gas technology have led to a significant increase in the power and muzzle velocity of these weapons. The risk of intracranial injury in children due to nonpowder weapons is poorly documented. METHODS A retrospective review was conducted at 3 institutions studying children 16 years or younger who had intracranial injuries secondary to nonpowder guns. RESULTS The authors reviewed 14 cases of intracranial injury in children from 3 institutions. Eleven (79%) of the 14 children were injured by BB guns, while 3 (21%) were injured by pellet guns. In 10 (71%) children, the injury was accidental. There was 1 recognized assault, but there were no suicide attempts; in the remaining 3 patients, the intention was indeterminate. There were no mortalities among the patients in this series. Ten (71%) of the children required operative intervention, and 6 (43%) were left with permanent neurological injuries, including epilepsy, cognitive deficits, hydrocephalus, diplopia, visual field cut, and blindness. CONCLUSIONS Nonpowder guns are weapons with the ability to penetrate a child's skull and brain. Awareness should be raised among parents, children, and policy makers as to the risk posed by these weapons.

    Injuries to oral soft-tissues can occur due to accidental, iatrogenic, and factitious traumas. Traumatic lesions, whether chemical, physical, or thermal in nature, are among the most common in the mouth. A type of physical injury to the gingival tissues is self-inflicted. Sometimes the lesions are termed gingivitis artefacta. Self-inflicted gingival injuries in children and adolescents can occur as a result of accidental trauma, premeditated infliction, or chronic habits such as fingernail biting, digit sucking, or sucking on objects such as pens, pencils or pacifiers. The purpose of this case report was to illustrate the destructive nature of the habit and to describe the successful treatment of this case. A 14-year-old girl with moderate pain, gingival bleeding and recession in the anterior mandibulary region was admitted to periodontology clinic. Upon questioning, the patient readily admitted traumatizing her gingiva with her fingernail. Treatment consisted of oral hygiene instruction, mechanical debridement, psychological support and surgical periodontal treatment. Postoperatively, complete root coverage, gains in clinical attachment levels, and highly significant increases in the width of keratinized gingiva were observed. This case report shows that it is possible to treat gingival injury and maintain the periodontal health of a patient with destructive habit. Patient compliance, regular dental follow-ups, and psychological support may be useful in stabilizing the periodontal condition of these patients. Dentists must be aware that self-inflicted gingival injury, although thought to be uncommon, is quite widespread. PMID:19421397

    Water skiing, boat racing, skin and scuba diving, as well as pleasure boat cruising are becoming increasingly popular hobbies. As a result, the incidence of injuries secondary to motor propellers is becoming more frequent. Injuries by propellers, amputation, death by drowning, and bleeding are rare reported events in forensic literature. The most common circumstances surrounding boat-propeller-related injuries are concerned with getting into or out of the boat, personal watercraft use or water skiing, and falling or being thrown from the boat. A case of a scuba diver's death that occurred during an illegal scuba fishing trip around a desalination plant is presented. A complete autopsy and histological study of all organs and surfaces of dismembered cadaveric sections, performed in order to determine the phases of death, are reported. An underwater scene investigation was conducted by an engineering team studying the mouth of the pump and the dynamic characteristic of rotating propeller blades.

    Full Text Available ABSTRACTOBJECTIVE: To evaluate the influence of oral supplementation with arginine on regeneration of injuries due to straining of the anterior tibial muscle of rats. METHODS: Twenty-four Wistar rats of weight 492.5 ± 50.45 g were used. Injuries were induced through straining the anterior tibial muscles. The rats were separated into three groups of eight rats each. In the untreated group (UTG, after induction of injuries, the rats were observed for 24 h. In the simulation group (SG and the arginine group (AG respectively, the rats received isotonic saline solution and arginine solution via direct gavage, over a seven-day period. At the end of the period, blood samples were collected for serum evaluations of creatine kinase (CK, lactic dehydrogenase (LDH, aspartate aminotransferase (AST and C-reactive protein (CRP. The right and left anterior tibial muscles were resected for histopathological evaluations on the muscle injuries, investigating edema, hemorrhage and disorganization or morphometric alteration of the muscle fibers. The tissue repair was investigated in terms of proliferation of adipose tissue, angiogenesis and collagen fibers. The ANOVA and Student's tmethods were used and p≤ 0.05 was taken to be statistically significant. RESULTS: In the serum evaluations, the AG showed lower CK assay values and higher AST values. In the histopathological evaluation, the UTG presented edema and hemorrhage compatible with injuries due to strain; the SG presented edema and hemorrhage with proliferation of adipose tissue and collagen fibers; and the AG presented not only the findings of the SG but also, especially, intense angiogenesis. CONCLUSION: Oral supplementation with arginine did not cause any significant metabolic alterations that would contraindicate its use and it induced angiogenesis during the repair of muscles injured due to strain.

    Full Text Available Introduction : Approximately 55% of women in Europe die from cardiovascular events, mostly as a result of coronary diseases and cerebral stroke. There is a 10-year shift in the cardiovascular risk between women and men. The risk in a 55-year-old female patient is similar to that of a 45-year-old man, thus the risk among women increases rapidly around the age of 50, when menopause prevails to occur. The purpose of the study was to assess and compare the SCORE-predicted risk of a fatal cardiovascular incident in pre- and postmenopausal women. Material and methods : The cross-sectional study was conducted as part of community nursing practice. It covered 219 women – inhabitants of Krakow, aged from 30 to 65, without clinically validated cardiovascular diseases of arteriosclerotic and/or diabetic origin, who volunteered to take part in the study. The group was divided into three subgroups: K1 – menstruating women (n = 113, K2a – women after natural menopause (n = 88, and K2b – women after surgical menopause (n = 18. The study made use of a lifestyle questionnaire, which concerned the social and economic status, and lifestyle habits including tobacco smoking. Arterial blood pressure was measured, and total cholesterol concentration in blood (mmol/l was recorded. Results : A high (≥ 5% level of the SCORE risk was discovered in 14.3% of postmenopausal women, as compared to 0.9% in the group of menstruating women. An average risk of a fatal cardiovascular incident during the following 10 years was significantly higher among women from groups K2a (2.61% and K2b (2.32% as compared to K1 – menstruating women (0.38%. No difference was, however, discovered between groups of naturally (K2a and surgically menopausal women (K2b. Conclusions : A significantly higher risk of SCORE-predicted death caused by a cardiovascular incident, as compared to the group of women in the premenopausal period, is characteristic of women in the postmenopausal period.

    Hyperpermeability is a crux of pathogenesis of sudden lung edema in many pulmooary disorders,espe=cially in acute lung injury and adult respiratory distress syndrome(ARDS). Using our modified method for assessment of pulmonary vascular permeability,we observed the effects of xanthine with xanthine oxi-dase (X-XO) perfused in rat pulmonary artery and the protection of vasoactive intestinal polypeptide (VIP) against the injury of pulmonary vascular permesbility.After addition of xanthine oxidase in the perfusate reservoir containing xanthine,125I-albumin leak index (125IALI) was remarkably increased while peak airway pressure (Paw) was not significantly increased,and perfusion pressure of pulmonary artery (Ppa) and lung wet/dry weight ratio (W/D) were only slightly increased.Xanthine plus xanthine oxi-dase also increased thromboxane B2(TX B2) and 6-keto-prostaglandin F1α(6-keto-PGF1α) in the perfusat-e.Treatment with VIP obviously reduced or totally prevented all signs of injury.Simultaneously,VIP also diminished or abolished the associated generation of arachidonate products.The results indicated that VIP bas potent protective activity against injury of pulmonary vasculat permeability and may be a physiological modulator of inflammatory damage to vaseular eodothelium associated with toxic oxygen metabolites.

    Sulindac is a long-acting nonsteroidal anti-inflammatory drug (NSAID) widely used for the management of osteoarthritis, rheumatoid arthritis, ankylosing sponydlitis, and acute gouty arthritis. Reports of sulindac toxicity in the literature are rare. We report the case of a 22-year old male with a history of bipolar disorder who was brought to the emergency department after ingesting approximately 15 g of sulindac in a suicide attempt. He was found to have acute kidney injury and hyperbilirubinemia. Despite aggressive fluid resuscitation, his renal function progressively worsened requiring the initiation of hemodialysis. Ten days following ingestion of sulindac, he began to develop ischemic skin changes with a gangrenous appearance in his hands and feet. He continued to receive supportive treatment, and his acute kidney injury, hyperbillirubinemia, and ischemic skin necrosis eventually resolved. Clinicians should be aware of this long-acting NSAID and its ability to cause prolonged multisystem organ dysfunction.

    Almost one-fifth of children who sustain a traumatic brain injury (TBI) are under the risk of attention problems after injury. The efficacy and tolerability of methylphenidate (MPH) in children with a history of TBI have not been completely identified. In this case report, MPH-induced manic symptoms in an adolescent with TBI will be summarized. A male patient aged 17 years was admitted with the complaints of attention difficulties on schoolwork and forgetfullness which became evident after TBI. Long-acting MPH was administered with the dose of 18 mg/day for attention problems. After one week, patient presented with the complaints of talking to himself, delusional thoughts, irritability and sleeplessness. This case highlights the fact that therapeutic dose of MPH may cause mania-like symptoms in children with TBI. Close monitarization and slow dose titration are crucial when considering MPH in children with TBI. PMID:27489389

    Full Text Available Abstract Introduction Independent lung ventilation is a form of protective ventilation strategy used in adult asymmetric acute lung injury, where the application of conventional mechanical ventilation can produce ventilator-induced lung injury and ventilation-perfusion mismatch. Only a few experiences have been published on the use of independent lung ventilation in newborn patients. Case presentation We present a case of independent lung ventilation in a 16-day-old infant of 3.5 kg body weight who had an asymmetric lung injury due to respiratory syncytial virus bronchiolitis. We used independent lung ventilation applying conventional protective pressure controlled ventilation to the less-compromised lung, with a respiratory frequency proportional to the age of the patient, and a pressure controlled high-frequency ventilation to the atelectatic lung. This was done because a single tube conventional ventilation protective strategy would have exposed the less-compromised lung to a high mean airways pressure. The target of independent lung ventilation is to provide adequate gas exchange at a safe mean airways pressure level and to expand the atelectatic lung. Independent lung ventilation was accomplished for 24 hours. Daily chest radiograph and gas exchange were used to evaluate the efficacy of independent lung ventilation. Extubation was performed after 48 hours of conventional single-tube mechanical ventilation following independent lung ventilation. Conclusion This case report demonstrates the feasibility of independent lung ventilation with two separate tubes in neonates as a treatment of an asymmetric acute lung injury.

    Mercury is a toxic heavy metal and occurs in organic and inorganic forms. Inorganic mercury includes elemental mercury and mercury salts. Mercury salts are usually white powder or crystals, and widely used in indigenous medicines and folk remedies in Asia. Inorganic mercury poisoning causes acute kidney injury (AKI) and gastrointestinal manifestations and can be life-threatening. We describe a case with unknown substance poisoning who developed AKI and disseminated intravascular coagulation (DIC). Renal biopsy showed acute tubular necrosis. Later, the consumed substance was proven to be mercuric chloride. His renal failure improved over time, and his creatinine normalized after 2 months. PMID:27194836

    Full Text Available Kidney stones are very common and unfortunately do not spare the pregnant population. Anatomical and pathophysiological changes occur in the pregnant females that alter the risk for development of urolithiasis. Acute renal colic during pregnancy is associated with significant potential risks to both mother and fetus. Diagnosis is often challenging because good imaging options without radiation use are limited. Management of diagnosed urolithiasis is unique in the pregnant population and requires multi-disciplinary care. Herein, we report a case of pregnancy which occurred in a state of pre-existing bilateral renal calculi with compromised renal function which subsequently developed into acute kidney injury, and requiring definitive management in the form of PCNL after termination of pregnancy.

    Full Text Available BackgroundAlthough the effects of opioids on intracranial pressure have long been a subject of controversy, they are frequently administered to patients with severe head trauma. We present a patient with an uncommon paradoxical response to opioids.Case ReportA patient with refractory intracranial hypertension after closed head injury was managed with standard medical therapy with only transient decreases in the intracranial pressure. Only after discontinuation of opiates did the intracranial pressure become manageable without metabolic suppression and rescue osmotic therapy, implicating opiates as the etiology of refractory intracranial hypertension in this patient. ConclusionsClinicians should consider opioids as a contributing factor in malignant intracranial hypertension when findings on neuroimaging do not explain persistent and refractory intracranial hypertension.

    Full Text Available The prevention and treatment of traumatic brain injury (TBI attributable to rapid-onset natural disasters is a major challenge confronting disaster preparedness planners and emergency medical personnel responding to those incidents. The kinetic energy released by rapid-onset natural disasters such as earthquakes, hurricanes or typhoons, and tornadoes can cause mild, moderate or severe TBIs. As a result, neurotrauma is a major risk factor for mortality and morbidity outcomes within the spatial domain impacted by a rapid-onset natural disaster. This review article elucidates major challenges associated with immediate emergency medical response, long-term care, and prevention of post-event increases in pediatric TBIs because of child abuse when rapid-onset natural disasters occur.

    Full Text Available Background: Traffic accidents, with lots of casualties and injuries, cause a lot of economic loss. This study was conducted to determine the Years Lived with Disability (YLD due to road traffic accidents according to the nature of injuries in Kermanshah province. Methods: following a pilot study, a sample of 3258 people was analyzed in order to calculate the YLD. Then, based on various factors, the age, gender and nature of injury of 10070 people were estimated. The YLD was calculated using the Global Burden of Disease (GBD (2010. The data concerning age and gender of the total population of the province was taken from the Statistical Center of Iran. All calculations were performed based on age and gender in Excel software. Results: The mean age of the injured people was 32.7±17.1. Men constituted 67.7 % of patients. The incidence rate of traffic accidents was 283.6 per 100,000. The highest levels of YLD in outpatients, men and women were reported for patella, tibia, fibula and ankle fractures and fractures of clavicle, scapula, humerus and skull, respectively. The highest rate of inpatient YLDs by nature of injury belonged to the fractures of sternum, ribs and face bone. The years lived with disability was calculated to be 2365.96 years (2.46 per 1000 and 1039.01 years (1.1 per 1000 for men and women, respectively. It was 3404.97 years (1.79 per 1000 in both genders. The highest YLD was in the age group of 15–29. Conclusion: Traffic accidents are high rate of YLD is resulted by traffic accidents. The most affected age group are youngsters and fracture are more frequent.

    A 66-year-old man, who was a passenger in a car involved in a low-speed head-on motor vehicle accident, was rushed to our hospital. His abdomen was tender and distended. An enhanced computed tomography scan showed a massive retroperitoneal hematoma, and its three-dimensional imaging revealed an active leak of the contrast medium from the aortic bifurcation. He went into shock, and was immediately transferred to the operating theater. Through a median laparotomy, a ruptured site measuring 5 mm in diameter was found at the aortic bifurcation and it was closed with sutures under a proximal aortic control. The other organs showed no evidence of injury. Because of the remarkable edema of the bowel, mesentery, and retroperitoneum, the abdomen was temporarily closed with a mesh sheet to prevent the occurrence of abdominal compartment syndrome. A delayed closure was then successfully performed 4 days later, and he was discharged with no residual sequelae 17 days after the initial operation.

    Full Text Available Background Traumatic brain injury (TBI is a major health problem worldwide. Secondary injuries after TBI, including diffuse axonal injury (DAI often occur, and proper treatments are needed in this regard. It has been shown that glibenclamide could reduce secondary brain damage after experimental TBI and improve outcomes. Objectives We aim to evaluate the role of glibenclamide on the short-term outcome of patients with DAI due to moderate to severe TBI. Patients and Methods In this controlled randomized clinical trial, 40 patients with moderate to severe TBI were assigned to glibenclamide (n = 20 and control (n = 20 groups. Six hours after admission the intervention group received 1.25 mg glibenclamide every 12 hours. The Glasgow coma scale (GCS was administered at admission, in the first 24 and 48 hours, at one week post-trauma and at discharge. The Glasgow outcome scale (GOS was also administered at discharge. All results were evaluated and compared between groups. Results Patients treated with glibenclamide compared to the control group had a significantly better GCS score one week post-trauma (P = 0.003 and at discharge (P = 0.004, as well as a better GOS score at discharge (P = 0.001. The glibenclamide group also had a shorter length of hospital stay compared to the control group (P = 0.03. In the control group, two patients (10% died during the first week post-trauma, but there was no mortality in the glibenclamide group (P = 0.48. Conclusions Treatment with glibenclamide in patients with DAI due to moderate to severe TBI significantly improves short-term outcomes.

    Analysis of the mortality due to cardiovascular diseases (CVD) can provide subsidies for preventive and control measures. The goal of this article is to compare CVD mortality rates in São Caetano do Sul, the state of São Paulo and the country as a whole. Standardized mortality and mortality due to CVD were calculated for the 1980-2010 period. We found a significant reduction in cardiovascular mortality in all three study units during this period, with the largest reduction in CVD in São Caetano do Sul. The largest mortality rate was found in the state of São Paulo. In adults 30 to 59, the CVD mortality rate in São Caetano do Sul was three times as high in men as in women, yet among adults 60 and older, CVD mortality was higher in women than in men. The lower rate is the result of implementing different healthcare policies. However, specific interventions are required that focus on changes in lifestyle, especially among adult men and the elderly.

    Recent growth in the electronics and chemical industries has brought about a progressive increase in the use of hydrofluoric acid (HF), along with the concomitant risk of acute poisoning among HF workers. We report severe cases of inhalation exposure and skin injury which were successfully treated by administering a 5% calcium gluconate solution with a nebulizer and applying 2.5% calcium gluconate jelly, respectively. Case 1: A 52-year old worker used HF for surface treatment after welding stainless steel, and was hospitalized with rapid onset of severe dyspnea. On admission to the critical care medical center he had widespread wheezing and crackles in his lungs. Chest radiograph showed a fine diffuse veiling over both lower pulmonary fields. Severe hypocalcemia with high concentrations of F in serum and urine were disclosed. He was immediately given 5% calcium gluconate solution by intermittent positive-pressure breathing (IPPB), utilizing a nebulizer. On the 21st hospital day, chest film and CT scan did not demonstrate any abnormality. He was discharged very much improved on the 22nd hospital day. Case 2: A 35-year old worker at an electronics factory was admitted to his local hospital with severe skin burn on his face and neck after exposure to 100% HF. Treatment began with immediate copious washing with water for 20 min. Calcium gluconate 2.5% gel (HF burn jelly) was applied to the area as a first-aid measure. Persistent high concentrations of serum and urinary F were disclosed for 2 weeks. After treatment with applications of HF burn jelly, he was confirmed as being completely recovered. The present cases and a review of published data suggest that an adequate method of emergency treatment for accidental HF poisoning is necessary.

    Full Text Available OBJECTIVE: To describe mortality due to cardiovascular diseases in women during the reproductive age (15 to 49 years in the state of São Paulo, Brazil, from 1991 to 1995. METHODS: A list of all deaths and their underlying causes, coded according to the International Classification of Diseases, 9th revision, multiple causes of death, and estimates of the female population according to age groups were provided by the SEADE Foundation. Specific coefficients for 100 thousand women for each year as well as the medians of these coefficients related to 5 years, and the percentage of death by subgroups were calculated. RESULTS: Cerebrovascular diseases have the highest coefficients (14.24 for 100 thousand females, followed by ischemic heart disease (7.37, other heart diseases (6.39, hypertensive disease (3.03, chronic rheumatic heart disease (1.58, pulmonary vascular diseases (1.29, and active rheumatic fever (0.05. Systemic arterial hypertension, as an associated cause, occurred in 55.3% to 57.8% of all the deaths due to intracerebral hemorrhage and in 30.4% to 30.8% due to subarachnoid hemorrhage. CONCLUSION: The significance of cerebrovascular diseases, coronary artery disease, and systemic arterial hypertension as causes of mortality suggests the need to emphasize preventive actions for young women who have the potential to reproduce to avoid possible complications in future pregnancies, and premature mortality.

    2012-09-01

    During 2002-2011, active component U.S. service members sustained 4,657 firearm-related injuries in circumstances other than deployment to the wars in Iraq/Afghanistan; 35 percent of the injuries were fatal. The highest firearm-related injury rates reflected service members in law enforcement/security and combat occupations. Of fatal injuries, 28 percent and 24 percent were suicides and homicides, respectively; among service members 30 and older, 84 percent of noncombat firearm-related deaths were suicides and 14 percent were homicides. In circumstances other than war, rates of both fatal and nonfatal firearm- related injuries are much lower among military members than civilian males aged 18-44. During the period, rates of nonfatal firearm-related injuries among non-deployed military members increased sharply, peaking in 2008. The trend reflects that among U.S. civilian males aged 18-44. However, firearm-related fatality rates were stable among civilians but increased among military members. The increase in rates of firearm-related fatalities among non-deployed military members reflects the increase in rates of suicides by firearms. Rates of injuries due to BB, pellet or paintball guns also increased during the period.

    The aim of this study was to compare the outcome and clinical course of multiple trauma patients with accidental or intentional (suicide related) fall from heights > 4 m. 211 patients with an injury severity score (ISS) > 17 were assigned to the following groups: I: intentional fall, n = 94; A: accidental fall, n = 117) and ISS (I: 28 +/- 1; A: 30 +/- 1), ventilation time (I: 16 +/- 2; A: 15 +/- 1) were not different. Significant differences were found in sex (m/f: I: 56/44; A: 73/27%), fractures of lumbarspine (I: 34; A: 15%), pelvis (I: 51; A: 38%), lower leg (I: 47; A: 20%), pilon (I: 15; A: 5%), and os calcis (I: 17; A: 9%). Liver lacerations occurred more often after intentional fall (I: 16; A: 6%). Single or multiple organ failure (MOF) was diagnosed significantly more often in group A(I: 1; A: 8%). Main cause of death in both groups was single or multiple organ failure (MOF: I: 47; A: 69%) or related to brain-injuries (I: 35; A: 19%). Prognosis and rehabilitation of multiple trauma patients after intentional fall is related to brain-injuries, spine-fractures and the functional outcome of the injured lower leg. Prognosis of patients after accidental fall is related to the development of MOF during the ICU-course.

    Autism spectrum disorders (ASD) are neurodevelopment disorders that cause severe and pervasive impairment in socialization, communication, and behavior. Although the availability of antipsychotic treatment in ASD has expanded, we will be very careful with side effects of these pharmacological agents. Following this reasoning, emerging data indicate that some antipsychotics may be associated with cardiovascular adverse events (e.g., QT interval prolongation), suggesting that this could be correlated to sudden death. Quite interesting, substantial evidence from epidemiological and case-control studies indicates that omega-3 reduces the risk of cardiovascular mortality, particularly sudden cardiac death. In accordance to the above mentioned findings, as omega-3 fatty acids per se have a direct cardiovascular protective role, our paper hypothesized that omega-3 fatty acids supplementation in ASD patients treated with atypical antipsychotic drugs may reduce cardiac arrhythmias and hence sudden cardiac death.

  2. Expression of S100A6 in Rat Hippocampus after Traumatic Brain Injury Due to Lateral Head Acceleration

    2014-04-01

    Full Text Available In a rat model of traumatic brain injury (TBI, we investigated changes in cognitive function and S100A6 expression in the hippocampus. TBI-associated changes in this protein have not previously been reported. Rat S100A6 was studied via immunohistochemical staining, Western blot, and reverse transcription-polymerase chain reaction (RT-PCR after either lateral head acceleration or sham. Reduced levels of S100A6 protein and mRNA were observed 1 h after TBI, followed by gradual increases over 6, 12, 24, and 72 h, and then a return to sham level at 14 day. Morris water maze (MWM test was used to evaluate animal spatial cognition. TBI- and sham-rats showed an apparent learning curve, expressed as escape latency. Although TBI-rats displayed a relatively poorer cognitive ability than sham-rats, the disparity was not significant early post-injury. Marked cognitive deficits in TBI-rats were observed at 72 h post-injury compared with sham animals. TBI-rats showed decreased times in platform crossing in the daily MWM test; the performance at 72 h post-injury was the worst. In conclusion, a reduction in S100A6 may be one of the early events that lead to secondary cognitive decline after TBI, and its subsequent elevation is tightly linked with cognitive improvement. S100A6 may play important roles in neuronal degeneration and regeneration in TBI.

    Limb-kinetic apraxia (LKA) is defined as an execution disorder of movements, resulting from injury of the corticofugal tract (CFT) from the secondary motor area. Diagnosis of LKA is difficult because it is made by clinical observation of movements. In this study, using diffusion tensor tractography (DTT), we attempted to investigate injury of the CFT from the secondary motor area in patients with corona radiata infarct. Twenty patients with corona radiata infarct were recruited. A probabilistic tractography method was used in fiber tracking for reconstruction of the corticospinal tract (CST) and CFT. Fractional anisotropy (FA), mean diffusivity, and tract volume of the CSTs and CFTs from the dorsal premotor cortex (dPMC) and supplementary motor area (SMA) were measured. In the affected hemisphere, FA values of the CST from the precentral hand knob and the CFT from the dPMC were significantly decreased compared with those of the unaffected hemisphere (p corona radiata infarct, using DTT. Our results suggest that LKA ascribed to injury of the CFTs from the secondary motor area could be accompanied by injury of the CST ascribed to the corona radiata infarct.

    Aldosterone interacts with mineralocorticoid receptor (MR) to stimulate sodium reabsorption in renal tubules and may also affect the vasculature. Caveolin-1 (cav-1), an anchoring protein in plasmalemmal caveolae, binds steroid receptors and also endothelial nitric oxide synthase, thus limiting its translocation and activation. To test for potential MR/cav-1 interaction in the vasculature, we investigated if MR blockade in cav-1-replete or -deficient states would alter vascular function in a mouse model of low nitric oxide (NO)-high angiotensin II (AngII)-induced cardiovascular injury. Wild-type (WT) and cav-1 knockout mice (cav-1(-/-)) consuming a high salt diet (4% NaCl) received Nω-nitro-l-arginine methyl ester (L-NAME) (0.1-0.2 mg/ml in drinking water at days 1-11) plus AngII (0.7-2.8 mg/kg per day via an osmotic minipump at days 8-11) ± MR antagonist eplerenone (EPL) 100 mg/kg per day in food. In both genotypes, blood pressure increased with L-NAME + AngII. EPL minimally changed blood pressure, although its dose was sufficient to block MR and reverse cardiac expression of the injury markers cluster of differentiation 68 and plasminogen activator inhibitor-1 in L-NAME+AngII treated mice. In aortic rings, phenylephrine and KCl contraction was enhanced with EPL in L-NAME+AngII treated WT mice, but not cav-1(-/-) mice. AngII-induced contraction was not different, and angiotensin type 1 receptor expression was reduced in L-NAME + AngII treated WT and cav-1(-/-) mice. In WT mice, acetylcholine-induced relaxation was enhanced with L-NAME + AngII treatment and reversed with EPL. Acetylcholine relaxation in cav-1(-/-) mice was greater than in WT mice, not modified by L-NAME + AngII or EPL, and blocked by ex vivo L-NAME, 1H-(1,2,4)oxadiazolo(4,3-a)quinoxalin-1-one (ODQ), or endothelium removal, suggesting the role of NO-cGMP. Cardiac endothelial NO synthase was increased in cav-1(-/-) versus WT mice, further increased with L-NAME + AngII, and not affected by EPL

    Full Text Available Purpose: This study aimed to investigate the effect of quercetin on apoptotic cell death induced by ischemia-reperfusion (I/R injury in the rat retina. Methods: Twenty-four rats were divided into four equal groups: control, ischemic, solvent, and quercetin. I/R injury was achieved by elevating the intraocular pressure above the perfusion pressure. Intraperitoneal injections of 20 mg/kg of quercetin and dimethyl sulfoxide (DMSO were performed in the quercetin and solvent groups, respectively, immediately prior to I/R injury, and the researchers allowed for the retinas to be reperfused. Forty-eight hours after injury, the thicknesses of the retinal ganglion cell layer (RGCL, inner nuclear layer (INL, inner plexiform layer (IPL, outer plexiform layer (OPL, and outer nuclear layer (ONL were measured in all groups. Moreover, the numbers of terminal deoxynucleotidyl transferase dUTP nick-end-labeled [TUNEL (+] cells and caspase-3 (+ cells in both INL and ONL were evaluated in all groups. Results: The administration of quercetin was found to reduce the thinning of all retinal layers. The mean thickness of INL in the quercetin and ischemic groups was 21 ± 5.6 µm and 16 ± 6.4 µm, respectively (P<0.05. Similarly, the mean thickness of ONL in the quercetin and ischemic groups was 50 ± 12.8 µm and 40 ± 8.7 µm, respectively (P<0.05. The antiapoptotic effect of quercetin in terms of reducing the numbers of both TUNEL (+ cells and caspase-3 (+ cells was significant in INL. The mean number of TUNEL (+ cells in INL in the ischemic and quercetin groups was 476.8 ± 45.6/mm2 and 238.72 ± 251/mm2, respectively (P<0.005. The mean number of caspase-3 (+ cells in INL of ischemic and quercetin groups was 633.6 ± 38.7/mm2 and 342.4 ± 36.1/mm2, respectively (P<0.001. Conclusion: The use of quercetin may be beneficial in the treatment of retinal I/R injury because of its antiapoptotic effect on the retinal layers, particularly in INL.

Materials and methods: We collected data on a total of 321 players belonging to the Sports Club "CUS Rugby Perugia" for a total of three years taking into consideration the type of injury, the part of the body concerned, if the injury occurred during official competitions or in training, and also the lapse of time necessary for recovery. Results: We had a total of 240 accidents (45.8% of minor gravity, 36.6% of average gravity and 17.6% serious. In relation to the type of trauma, we noticed that minor injuries consisted in most cases and above all in facial injuries, while the average and the serious severity accidents affected in most cases the knees: (sprains, meniscal and ligamentous tears. Discussion: By analyzing the collected data we have noticedthat the highest number of accidents occurred during official competitions, and especially during the last minutes of the game, probably due to a greater muscle fatigue. The role of the players is also important because it correlates to a different type of risk. Conclusions: This study confirms that rugby has a higher accident rate than other contact sports. Therefore specific training strategies and techniques should be implemented, in order to reduce the incidence of injuries, especially at the level of the lower limbs.

    This study aimed to investigate the impact of dust storms on short-term mortality in Kuwait. We analyzed respiratory and cardiovascular mortality as well as all-cause mortality in relation to dust storm events over a 5-year study period, using data obtained through a population-based retrospective ecological time series study. Dust storm days were identified when the national daily average of PM10 exceeded 200 μg/m3. Generalized additive models with Poisson link were used to estimate the relative risk (RR) of age-stratified daily mortality associated with dust events, after adjusting for potential confounders including weather variables and long-term trends. There was no significant association between dust storm events and same-day respiratory mortality (RR = 0.96; 95 %CI 0.88-1.04), cardiovascular mortality (RR = 0.98; 95 %CI 0.96-1.012) or all-cause mortality (RR = 0.99; 95 %CI 0.97-1.00). Overall our findings suggest that local dust, that most likely originates from crustal materials, has little impact on short-term respiratory, cardiovascular or all-cause mortality.

    Acute scrotum is a critical clinical entity in children. This report presents a 12-year-old boy presented with recurrent epididymo-orchitis (EO) with a history of pelvic trauma and urethral disruption 10 years ago. Antegrade and retrograde studies confirmed urethrovasal reflux. The patient did not respond to prophylactic antibiotics, clean intermittent catheterization and endoscopic injection of bulking agent at the junction of the ejaculatory duct and posterior urethra. As the last option, neurovascular sparing vas clipping was performed and the patient made a full recovery. This is the first report of this technique in the treatment for recurrent EO caused by traumatic injury.

    During clinical endodontic treatment, we often find radiopaque filling material beyond the root apex. Accidental extrusion of calcium hydroxide could cause the injury of inferior alveolar nerve, such as paresthesia or continuous inflammatory response. This case report presents the extrusion of calcium hydroxide and treatment procedures including surgical intervention. A 48 yr old female patient experienced Calcipex II extrusion in to the inferior alveolar canal on left mandibular area during endodontic treatment. After completion of endodontic treatment on left mandibular first molar, surgical intervention was planned under general anesthesia. After cortical bone osteotomy and debridement, neuroma resection and neurorrhaphy was performed, and prognosis was observed. But no improvement in sensory nerve was seen following surgical intervention after 20 mon. A clinician should be aware of extrusion of intracanal medicaments and the possibility of damage on inferior alveolar canal. Injectable type of calcium hydroxide should be applied with care for preventing nerve injury. The alternative delivery method such as lentulo spiral was suggested on the posterior mandibular molar.

  17. A multibody approach applied to the study of driver injuries due to a narrow-track wheeled tractor rollover

    Full Text Available This paper proposes the use of the multibody approach to evaluate the severity of the injuries to the driver associated with rollover of an agricultural tractor. A simple rollover accident of a narrow-track wheeled tractor was simulated in the multibody-FEM Madymo environment and the biomechanical damage to the operator with and without 2-point pelvic restraint was analysed. The structure of the tractor was considered to be unbendable, whereas i infinitely rigid, ii clay-based and iii sand-based soils have been studied. The obtained results highlight the important role played by the seat belt in confining the farm operator within the safety volume maintained by the rollover protective structure (ROPS of the tractor so that the injuries are reduced. The deformation of the soil produces lower acceleration and velocity values than those obtained with a rigid soil. On the other hand, as soil plastic deformations increase, the penetration of ROPS into the soil also increases, thus reducing the safety volume of the tractor and increasing the probability of interactions between the operator and the soil.

    Abdominal visceral injuries are encountered by every surgeon who deals with trauma. It is simple and useful to divide abdominal visceral injuries into those caused by penetrating mechanisms of injury and those due to blunt mechanisms. Determination of the need for operative intervention is generally easier after penetrating trauma. Gunshot wounds to the abdomen should be explored, as should stab wounds to the anterior abdomen that penetrate the fascia. A midline incision is the standard approach to abdominal visceral injuries because of its ease and versatility. Abdominal exploration should be consistent and systemic so as not to miss significant injuries. Hollow viscus injury is most common after penetrating injury, while blunt injury most often results in injury to solid viscera. Diagnostic and operative aspects of the treatment of specific visceral injuries are reviewed.

    Full Text Available Background: Retinal detachment (RD following ocular trauma often results in guarded visual prognosis and sometimes leads to loss of the eye. With the advent of microincisional vitrectomy surgery and the development of surgical techniques, the management of ocular trauma has been transformed. Case Presentation: A 34-year-old man sustained an open globe injury from fragmented glass at work. He received primary repair and another follow-up surgery 9 days later, including vitrectomy, silicone oil tamponade, and lensectomy for RD and traumatic cataract at another medical center. However, his retina was totally detached and completely curled up in a roll with choroid on display when he was seen by us 1 month later. He was managed with vigilant and patient peeling and unfolding of the retina using a 23-gauge forceps and silicone oil tamponade, and achieved anatomical success and preservation of his eye at 6-month follow-up. Conclusions: This report demonstrates that even in cases which appear to be hopeless at presentation, the surgeon’s perseverance and surgical technique can salvage an eye that may otherwise be phthisical. It also encourages retinal surgeons to use microincisional vitrectomy to manage severe traumatic RD.

    Full Text Available Abstract Background Combined iatrogenic vascular and biliary injury during cholecystectomy resulting in ischemic hepatic necrosis is a very rare cause of acute liver failure. We describe a patient who developed fulminant liver failure as a result of severe cholestasis and liver gangrene secondary to iatrogenic combine injury or the hepatic pedicle (i.e. hepatic artery, portal vein and bile duct during laparoscopic cholecystectomy. Case presentation A 40-years-old woman underwent laparoscopic cholecystectomy for acute cholecystitis. During laparoscopy, a severe bleeding at the liver hilum motivated the conversion to open surgery. Many sutures were placed across the parenchyma for bleeding control. After 48 hours, she rapidly deteriorated with encephalopathy, coagulopathy, persistent hypotension and progressive organ dysfunction including acute renal failure requiring hemodialysis and mechanical ventilation. An angiography documented an occlusion of right hepatic artery and right portal vein. In the clinical of acute liver failure secondary to liver gangrene, severe coagulopathy and progressive secondary multi-organ failure, the patient was included in the waiting list for liver transplantation. Two days later, the patient was successfully transplanted with initial adequate liver graft function. However, she developed bilateral pneumonia and severe gastrointestinal bleeding and finally died 24 days after transplantation due to bilateral necrotizing pneumonia. Conclusion The occurrence of acute liver failure due to portal triad injury during laparoscopic cholecystectomy is a catastrophic complication. Probably, the indication of liver transplantation as a life-saving strategy in patients with late diagnosis, acute liver failure, severe coagulopathy and progressive secondary multi-organ failure could be considered but only minimizing immunosuppressive regimen to avoid postoperative infections.

    Full Text Available Rectus Sheath Hematoma (RSH represents an unusual entity which is characterized by acute abdominal pain and tender palpable abdominal mass usually, among elderly patients receiving anticoagulant therapy. We report the case of an 81-year-old woman admitted to our department due to acute abdominal pain and oligoanuria. The patient had recently been hospitalized due to acute myocardial infarction (AMI and atrial fibrillation (AF and received both anticoagulant and antiplatelet therapies. The radiological assessments revealed an extended Rectus Sheath Hematoma and bilateral hydronephrosis. Treatment of the hematoma required cessation of anticoagulants and antiplatelet agents, immobilization, blood and fresh frozen plasma transfusion, and administration of vasopressors. The patient recovered gradually and was discharged home fifteen (15 days later.

  4. Severe muscle atrophy due to spinal cord injury can be reversed in complete absence of peripheral nerves

    Simona Boncompagni

    2012-12-01

    Full Text Available In the last years, a new efficient treatment has been developed to treat paralyzed skeletal muscle of patients affected by spinal cord injury (SCI. The capability of the functional electrical stimulation (FES to improve trophism and in some cases muscle function, are now well documented both in animals after experimental cord lesion, and in humans, generally after traumatic cord lesion. This new findings makes FES an important tool for the rehabilitation of SCI patients. FES stimulation has been proven to be an effective method used to retard muscle atrophy and improve recovery after reinnervation. Sophisticated FES devices have been developed for restoring function in the upper and lower extremities, the bladder and bowel, and the respiratory system of SCI patients. However, there are SCI cases, such as those affected by flaccid paralysis, in which the musculature is not treated with FES rehabilitation therapy. This is because conventional FES apparatuses are designed for direct stimulation of peripheral nerves that need small currents to be depolarized, and are not effective in patients that have lost their peripheral nerves, and, therefore, require higher currents for the direct depolarization of the muscle fibers. Lack of muscle treatment generates, as a secondary problem, a long series of alterations to tissues other than muscle, such as bones (osteoporosis, skin (pressure sores, decubital ulcers, etc., that are a direct consequence of inactivity and poor blood supply to the denervated areas. These complications represent an extremely serious problem for the general health of the injured individuals, who usually have a shorter than normal life span. In the hopes of changing this common belief, an innovative rehabilitation procedure, based on FES, has been developed with the aim of reversing long-lasting muscle atrophy in the muscles of the lower extremities of SCI patients affected by complete lesion of the conus cauda, i.e. that have no

    Full Text Available Any new clinical data, whether positive or negative, generated about a medical device should be published because health professionals should know which devices do not work, as well as those which do. We report three spinal cord injury patients in whom urological implants failed to work. In the first, paraplegic, patient, a sacral anterior root stimulator failed to produce erection, and a drug delivery system for intracavernosal administration of vasoactive drugs was therefore implanted; however, this implant never functioned (and, furthermore, such penile drug delivery systems to produce erection had effectively become obsolete following the advent of phosphodiesterase type 5 inhibitors. Subsequently, the sacral anterior root stimulator developed a malfunction and the patient therefore learned to perform self-catheterisation. In the second patient, also paraplegic, an artificial urinary sphincter was implanted but the patient developed a postoperative sacral pressure sore. Eight months later, a suprapubic cystostomy was performed as urethral catheterisation was very difficult. The pressure sore had not healed completely even after five years. In the third case, a sacral anterior root stimulator was implanted in a tetraplegic patient in whom, after five years, a penile sheath could not be fitted because of penile retraction. This patient was therefore established on urethral catheter drainage. Later, infection with Staphylococcus aureus around the receiver block necessitated its removal. In conclusion, spinal cord injury patients are at risk of developing pressure sores, wound infections, malfunction of implants, and the inability to use implants because of age-related changes, as well as running the risk of their implants becoming obsolete due to advances in medicine. Some surgical procedures such as dorsal rhizotomy are irreversible. Alternative treatments such as intermittent catheterisations may be less damaging than bladder stimulator in

    Spaceflight causes adaptive changes in cardiovascular function that may deleteriously affect crew health and safety. Over the last three decades, symptoms of cardiovascular changes have ranged from postflight orthostatic tachycardia and decreased exercise capacity to serious cardiac rhythm disturbances during extravehicular activities (EVA). The most documented symptom of cardiovascular dysfunction, postflight orthostatic intolerance, has affected a significant percentage of U.S. Space Shuttle astronauts. Problems of cardiovascular dysfunction associated with spaceflight are a concern to NASA. This has been particularly true during Shuttle flights where the primary concern is the crew's physical health, including the pilot's ability to land the Orbiter, and the crew's ability to quickly egress and move to safety should a dangerous condition arise. The study of astronauts during Shuttle activities is inherently more difficult than most human research. Consequently, sample sizes have been small and results have lacked consistency. Before the Extended Duration Orbiter Medical Project (EDOMP), there was a lack of normative data on changes in cardiovascular parameters during and after spaceflight. The EDOMP for the first time allowed studies on a large enough number of subjects to overcome some of these problems. There were three primary goals of the Cardiovascular EDOMP studies. The first was to establish, through descriptive studies, a normative data base of cardiovascular changes attributable to spaceflight. The second goal was to determine mechanisms of cardiovascular changes resulting from spaceflight (particularly orthostatic hypotension and cardiac rhythm disturbances). The third was to evaluate possible countermeasures. The Cardiovascular EDOMP studies involved parallel descriptive, mechanistic, and countermeasure evaluations.

    Cardiac troponin has been well described as the preferred biomarker for diagnosis of myocardial infarction due to the high sensitivity and specificity for myocardial injury. Numerous other conditions apart from acute coronary syndrome can also lead to small elevations in troponin levels. However, the use of cTn as prognostic biomarker for the primary assessment of cardiovascular risk in asymptomatic patient has only recently been described. And with the development of newer generations of high-sensitivity cardiac troponin assays that can detect 10-fold lower concentrations of troponin, the potential value cTn in the prevention and management of asymptomatic cardiovascular disease has come to the fore. This review provides an overview of the transition of cardiac troponin as a marker of acute myocardial injury to one that detects sub-clinical injury. Evidence continues to show that high-sensitivity troponin is emerging as one of the most powerful prognostic biomarkers for the assessment of cardiovascular risk in the general population.

    Bicycling injuries can be classified into bicycle contact, traumatic, and overuse injuries. Despite the popularity of cycling, there are few scientific studies regarding injuries. Epidemiological studies are difficult to compare due to different methodologies and the diverse population of cyclists studied. There are only three studies conducted on top level professionals. Ninety-four percent of professionals in 1 year have experienced at least one overuse injury. Most overuse injuries are mild with limited time off the bike. The most common site of overuse injury is the knee, and the most common site of traumatic injury is the shoulder, with the clavicle having the most common fracture. Many overuse and bicycle contact ailments are relieved with simple bike adjustments.

And these damages caused by MS are much more detrimental than any single component among the cluster of risk factors. Recent studies have indicated autophagy is important in the onset and development of MS cardiovascular injury. Autophagy is closely correlated with MS cardiovascular diseases inuced by obesity, insulin resistance, hypertension, dyslipidemia, oxidative stress, and chronic inflammation. In this article, the pivotal role and pathogenesis of autophagy in MS cardiovascular damages are briefly reviewed based on international frontier research.

    The emergency care to stingrays envenomation permits, in the majority of cases, to limit the damage caused. In the case of delayed medical care, we can meet deep and extensive lesions that need to be thoroughly explored in order to better address their reconstruction. We report the case of a patient injured by freshwater stingray. He presented a necrotic defect of 6 cm in diameter under the right medial malleolus with bone exposure and neurovascular injury. We opted for a therapeutic strategy in two steps. The first step consisted in a large debridement of the necrotic defect, under appropriate antibiotics and negative pressure therapy. Three weeks later, we covered the defect with a distally based lesser saphenous vein veno-fascia-subcutaneous flap, covered with a split-thickness graft. The coverage of the defect was satisfactory. The infection was controlled with antibiotics, which we prolonged for one month. The patient presented, initially, hypoesthesia of the upper lateral foot in relation with a neurapraxis of the sural nerve. The symptoms resolved at two months. The foot edema due to venous stasis also resolved at two months. The donor site healed without complications. The ability to wear normal shoes was preserved. The patient resumed his daily activities promptly.

    The hypothalamic-pituitary dysfunction attributable to traumatic brain injury (TBI), aneurysmal subarachnoid hemorrhage (SAH), and ischemic stroke (IS) has been lately highlighted. The diagnosis of TBI-induced-hypopituitarism, defined as a deficient secretion of one or more pituitary hormones, is made similarly to the diagnosis of classical hypopituitarism because of hypothalamic/pituitary diseases. Hypopituitarism is believed to contribute to TBI-associated morbidity and to functional and cognitive final outcome, and quality-of-life impairment. Each pituitary hormone must be tested separately, since there is a variable pattern of hormone deficiency among patients with TBI-induced-hypopituitarism. Similarly, the SAH and IS may lead to pituitary dysfunction although the literature in this field is limited. The drive to diagnose hypopituitarism is the suspect that the secretion of one/more pituitary hormone may be subnormal. This suspicion can be based upon the knowledge that the patient has an appropriate clinical context in which hypopituitarism can be present, or a symptom known as caused by hypopituitarism. Hypopituitarism should be diagnosed as a combination of low peripheral and inappropriately normal/low pituitary hormones although their basal evaluation may be not distinctive due to pulsatile, circadian, or situational secretion of some hormones. Evaluation of the somatotroph and corticotroph axes require dynamic stimulation test (ITT for both axes, GHRH + arginine test for somatotroph axis) in order to clearly separate normal from deficient responses.

    Traumatic brain injury (TBI) is a devastating public health problem which may result in hypopituitarism. However, the mechanisms and the risk factors responsible for hypothalamo-pituitary dysfunction due to TBI are still unclear. Although APO E is one of the most abundant protein in hypothalamo-pituitary region, there is no study investigating the relation between APO E polymorphism and TBI-induced hypopituitarism. This study was undertaken to determine whether APO E genotypes modulate the pituitary dysfunction risk after TBI due to various causes, including traffic accident, boxing, and kickboxing. Ninety-three patients with TBI (mean age, 30.61 +/- 1.25 years) and 27 healthy controls (mean age, 29.03 +/- 1.70 years) were included in the study. Pituitary functions were evaluated, and APO E genotypes (E2/E2; E3/E3; E4/E4; E2/E3; E2/E4; E3/E4) were screened. Twenty-four of 93 subjects (25.8%) had pituitary dysfunction after TBI. The ratio of pituitary dysfunction was significantly lower in subjects with APO E3/E3 (17.7%) than the subjects without APO E3/E3 genotype (41.9%; p = 0.01), and the corresponding odds ratio was 0.29 (95% confidence interval [CI], 0.11-0.78). In conclusion, this study provides strong evidence for the first time that APO E polymorphism is associated with the development of TBI-induced pituitary dysfunction. Present data demonstrated that APO E3/E3 genotype decreases the risk of hypopituitarism after TBI. The demonstration of the association between the APO E polymorphism and TBI may provide a new point of view in this field and promote further studies.

    Democratic Republic of Congo (DRC), a particular form of juvenile delinquency and insecurity intensifies in the city of Kinshasa. This is the phenomenon Kuluna. It is organized gangs equipped with machetes and other weapons. The main objective of this study is to know the phenomenon Kuluna and describe the upper limb injuries caused by machetes, while insisting on the specifics of the management of these lesions in our communities. This retrospective descriptive study examines 14 cases of wounds of the hand and forearm due to stab phenomenon Kuluna, in Kinshasa. It covers the period from 1 November 2010 to 1 November 2013. Among the 14 patients with lesions in the hand and forearm admitted and treated at the Unit of Plastic Reconstructive and Aesthetic Surgery, Hand Surgery and Burns, University Clinics of Kinshasa to attacks due to the phenomenon Kuluna. We have 11 men and 3 women. The average age was 33, 5 years (extremes of 21 and 56 years). The right upper limb is reached that the left upper limb, respectively 12 patients and 2 patients. The lesions are localized to the wrist in the majority of cases (10 patients) in the palm of hand and in 3 patients in the fingers in 1 patient. The palmar surface is reached (10 cases) and the dorsal (4 cases). Zone 5 of the International Classification of flexor and Zone 8 topographic classification extensors at hand are the predilection sites of lesions respectively the palmar surface (6 out of 10) and the dorsal (2 case 4). The median nerve at the wrist is cut in half the cases. On bone lesions localized to the forearm, we observed a high incidence of fracture of the ulna (62.5%). The treatment begins with the stabilization of bone pieces, gestures revascularization and nerve sutures and suture tendon and finally skin coverage. Rehabilitation was mandatory, she supervises the actions of repair and it continues until the recovery of function.

    Background Chronic kidney disease (CKD) is a group of heterogeneous abnormalities affecting the function and structure of the kidney and mostly further proceeds to cardiovascular damage prior to end stage renal disease (ESRD). The oxidative insult and inflammatory mediators have some undefined role in CKD and cardiovascular complications. It is therefore, aimed at to pin point the predictive factors in the development of cardiovascular disorder in patients with chronic kidney disease. Methods Fifty patients of CKD experiencing cardiovascular distress and twenty normal individuals having same age and sex acted as control during these observations. Blood samples (Each 5 ml) were drawn and subjected to centrifugation for 10–15 minutes to separate the serum at 4000-5000rpm. The levels of MDA, GSH, SOD, CAT, VIT C, VIT E, IL-1, TNF-alpha, nitric oxide (NO) and advanced oxidation protein products (AOPPs) were estimated and analyzed. Results The nitric oxide levels in the CKD patients decreased significantly (13.26±1.25 ng/ml) compared to controls (42.15±5.26 ng/ml). The serum vitamin E and C levels in these patients recorded 2.15±0.25 μg/ml and 0.97±0.09 μg/ml respectively as against their assigned controls which read 6.35±1.22 μg/ml and 3.29±0.25 μg/ml. Furthermore, a significantly higher level of Malondialdehyde (MDA) as1.25±0.07 nmol/ml was observed in CKD patients viz-a-viz relevant control. However, the serum SOD, catalase (CAT) and GSH levels in the same patients registered a significant decline as evident from respective figures 0.07±0.002 μg/dl, 1.22±0.012 μmol/mol, and 3.25±1.05 μg/dl. The control for these was observed as0.99±0.06 μg/dl, 3.19±0.05 μmol/mol, and 8.64±0.03 μg/dL. On the other hand, the IL-1 levels in the CKD patients found quite higher (402.5±18.26 pg/ml). This clearly points to substantial increase in oxidative insult and reduced NO levels leading to the renal and cardiovascular damage. Conclusion Observations support

    The cardiovascular system is susceptible to a group of diseases that are responsible for a larger proportion of morbidity and mortality than any other disease. Many cardiovascular diseases are associated with a failure of defenses against oxidative stress-induced cellular damage and/or death, leading to organ dysfunction. The pleiotropic transcription factor, nuclear factor-erythroid (NF-E) 2-related factor 2 (Nrf2), regulates the expression of antioxidant enzymes and proteins through the antioxidant response element. Nrf2 is an important component in antioxidant defenses in cardiovascular diseases such as atherosclerosis, hypertension, and heart failure. Nrf2 is also involved in protection against oxidant stress during the processes of ischemia-reperfusion injury and aging. However, evidence suggests that Nrf2 activity does not always lead to a positive outcome and may accelerate the pathogenesis of some cardiovascular diseases (e.g., atherosclerosis). The precise conditions under which Nrf2 acts to attenuate or stimulate cardiovascular disease processes are unclear. Further studies on the cellular environments related to cardiovascular diseases that influence Nrf2 pathways are required before Nrf2 can be considered a therapeutic target for the treatment of cardiovascular diseases.

    Rhabdomyolysis (RM), also referred to as myonecrosis, is not an uncommon disorder of skeletal muscle, the incidence of which is on the increase as endurance tests, sports and body build have become popular. RM is divided into diffuse muscle fiber damage and musculotendinous unit (MTU) injury. A recent study by Crenshaw et al. revealed that muscular fiber damage caused by racing was associated with elevated intra-muscular pressure, capillary damage, and ischchemia. It is to be remembered that myocytes are mainly destroyed in RM whereas perimysial connective is predominantly damaged in myositis ossificans. When muscle fibers disrupt myoglobin escapes into extracellular fluid and plasma resulting in myoglobinemia and often acute renal failure. Plasma creatine phosphokinase level becomes elevated. We report a case of strenuous swimming-related RM that occurred in the muscles of the shoulder girdles and chest wall analyzed using magnified {sup 9}:9{sup m}Tc-HDP bone scan. Of interest magnified bone scan of RM in the present case showed not only ordinary muscular injury but also MTU injury. MRI is useful in the study of soft tissue injury and in recent years sonography has also become increasingly used. As mentioned {sup 99m}Tc-HDP bone scan, especially magnification scan, sensitively depicts metabolic change that occurred in injured muscles and tendons. Unless injury is trivial the bone scan nearly always reveals pathological uptake in a damaged muscle, MTU, and/or tendinous insertion permitting the topographic distinction of injury. Thus, the diagnosis of myolysis, MTU injury, and enthesitis can specifically be made when one uses magnification technique.

    In a one-year prospective study of 42 elite orienteers, 73 recent injuries (1.7 per runner per year) were found. Acute injuries totalled 52% and 48% were due to overuse. Ankle sprains made up 37% of acute injuries while the remaining were mainly contusions caused by falls or bumps against branches or rocks. Medial shin pain, Achilles peritendinitis, peroneal tenosynovitis and iliotibial band friction syndrome were the most frequent overuse injuries. All overuse injuries were located in the lower extremity while 18% of acute injuries was located elsewhere. Acute injuries were most frequent in the competitive season while overuse injuries occurred most often during the continuous training period.

    Human genetic variation in the form of single nucleotide polymorphisms as well as more complex structural variations such as insertions, deletions and copy number variants, is partially responsible for the clinical variation seen in response to pharmacotherapeutic drugs. This affects the likelihood of experiencing adverse drug reactions and also of achieving therapeutic success. In this paper, we review key studies in cardiovascular pharmacogenetics that reveal genetic variations underlying the outcomes of drug treatment in cardiovascular disease. Examples of genetic associations with drug efficacy and toxicity are described, including the roles of genetic variability in pharmacokinetics (e.g. drug metabolizing enzymes) and pharmacodynamics (e.g. drug targets). These findings have functional implications that could lead to the development of genetic tests aimed at minimizing drug toxicity and optimizing drug efficacy in cardiovascular medicine.

    Full Text Available A considerable percentage of electrical injuries occur as a result of work activities. Electrical injury can lead to various cardiovascular disorders: acute myocardial necrosis, myocardial ischemia, heart failure, arrhythmias, hemorrhagic pericarditis, acute hypertension with peripheral vasospasm, and anomalous, nonspecific ECG alterations. Ventricular fibrillation is the most common arrhythmia resulting from electrical injury and is the leading cause of death in electrical (especially low voltage alternating current injury cases. Asystole, premature ventricular contractions, ventricular tachycardia, conduction disorders (various degrees of heart blocks, bundle-brunch blocks, supraventricular tachycardia, and atrial fibrillation are the other arrhythmic complications of electrical injury. Complete atrioventricular block has rarely been reported and permanent pacemaker was required for the treatment in some of these cases. Herein, we present a case of reversible complete atrioventricular block due to low voltage electrical injury in a young electrical technician.

    Cardiovascular disease is among the world's leading causes of death, and nearly 80% of deaths occur in developing countries. Cardiovascular disease is becoming a major health problem in India, where life expectancy has increased with decreases in infectious disease and childhood mortality. It is well established that this population experiences coronary artery disease at a younger age than other populations. With infectious diseases still endemic, noncommunicable diseases are a lower priority for the governments of developing countries. There is a clear progression to degenerative and lifestyle-related diseases such as cardiovascular disease as a result of current social and economic change. The lack of a public response to the increasing risk for cardiovascular disease thus far is due mostly to a perception among policy makers and the public that cardiovascular disease is largely a problem of the urban rich. In conclusion, this review addresses the imminent threats and ways to tackle the epidemic in India.

  10. Whiplash injuries.

    2005-10-01

    Whiplash injuries are very common and usually are associated with rear-end collisions. However, a whiplash injury can be caused by any event that results in hyperextension and flexion of the cervical spine. These injuries are of serious concern to all consumers due to escalating cost of diagnosis, treatment, insurance, and litigation. Most acute whiplash injury cases respond well to conservative treatments, which result in resolution of symptoms usually within weeks to a few months after the injury occurred. Chronic whiplash injuries often are harder to diagnose and treat and often result in poor outcomes. Current research shows that various structures in the cervical spine receive nociceptive innervation and potentially may be the cause of chronic pain symptoms. One potential pain generator showing promise is the facet or zygapophyseal joints. Various researchers have proven that these joints are injured during whiplash injuries and that diagnosis and temporary pain relief can be obtained with facet joint injections. The initial evaluation of any patient should follow an organized and stepwise approach, and more serious causes of neck pain must first be ruled out through the history, physical examination, and diagnostic testing. Treatment regimens should be evidence-based, focusing on treatments that have proven to be effective in treating acute and chronic whiplash injuries.

    Low back pain is highly prevalent in nurses. This study aimed to determine which physical fitness, physical activity (PA) and biomechanical characteristics most clearly distinguish between nurses with [recently injured (RInj)] and without [not recently injured (NRInj)] a recent back injury. Twenty-seven (8 RInj, 19 NRInj) female nurses completed questionnaires (pain, work, PA), physical fitness, biomechanical and low back discomfort measures, and wore an accelerometer for one work shift. Relative to NRInj nurses, RInj nurses exhibited reduced lumbopelvic control (41.4% more displayed a moderate loss of frontal plane position), less active occupational behaviours (less moderate PA; less patient lifts performed alone; more sitting and less standing time) and more than two times higher low back discomfort scores. Despite no physical fitness differences, the lumbopelvic control, occupational behaviours and discomfort measures differed between nurses with and without recent back injuries. It is unclear whether poor lumbopelvic control is causal or adaptive in RInj nurses and may require further investigation. Practitioner Summary: It is unclear which personal modifiable factors are most clearly associated with low back pain in nurses. Lumbopelvic control was the only performance-based measure to distinguish between nurses with and without recent back injuries. Future research may investigate whether reduced lumbopelvic control is causal or adaptive in recently injured nurses.

    The global epidemic of cardiovascular disease remains the leading cause of death in the USA and across the world. Functional and structural integrity of mitochondria are essential for the physiological function of the cardiovascular system. The metabolic adaptation observed in normal heart is lost in the failing myocardium, which becomes progressively energy depleted leading to impaired myocardial contraction and relaxation. Uncoupling of electron transfer from ATP synthesis leads to excess generation of reactive species, leading to widespread cellular injury and cardiovascular disease. Accumulation of mitochondrial DNA mutation has been linked to ischaemic heart disease, cardiomyopathy and atherosclerotic vascular disease. Mitochondria are known to regulate apoptotic and autophagic pathways that have been shown to play an important role in the development of cardiomyopathy and atherosclerosis. A number of pharmacological and non-pharmacological treatment options have been explored in the management of mitochondrial diseases with variable success.

  13. Neuropeptides in cardiovascular control.

    Science.gov (United States)

    Ganong, W F

    1984-12-01

    Neuropeptides can affect cardiovascular function in various ways. They can serve as cotransmitters in the autonomic nervous system; for example, vasoactive intestinal peptide (VIP) is released with acetylcholine and neuropeptide Y with norepinephrine from postganglionic neurons. Substance P and, presumably, other peptides can can affect cardiovascular function when released near blood vessels by antidromically conducted impulses in branches of stimulated sensory neurons. In the central nervous system, many different neuropeptides appear to function as transmitters or contransmittes in the neural pathways that regulate the cardiovascular system. In addition neuropeptides such as vasopressin and angiotensin II also circulate as hormones that are involved in cardiovascular control. Large doses of exogenous vasopressin are required to increase blood pressure in normal animals because the increase in total peripheral resistance produced by the hormones is accompanied by a decrease in cardiac output. However, studies with synthetic peptides that selectively antagonize the vasopressor action of vasopressin indicate that circulating vasopressin is important in maintaining blood pressure when animals are hypovolemic due to dehydration, haemorrhage or adrenocortical insufficiency. VIP dilates blood vessels and stimulates renin secretion by a direct action on the juxtaglomerular cells. Renin secretion is stimulated when the concentration of VIP in plasma exceeds 75 pmol/litre, and higher values are seen in a number of conditions. Neostigmine, a drug which increases the secretion of endogenous VIP, also increases renin secretion, and this increase is not blocked by renal denervation or propranolol. Thus, VIP may be a physiologically significant renin stimulating hormone.(ABSTRACT TRUNCATED AT 250 WORDS)

    Purpose: To develop clinical practice guidelines (CPGs) for prevention, diagnosis, treatment and follow-up of ocular injuries caused by exposure to mustard gas. Methods: The clinical questions were designed by the guideline team. Websites and databases including National Guidelines Clearinghouse, National Institute for Clinical Excellence, Cochrane, and PubMed were searched to find related CPGs and explore possible answers to the clinical questions. Since there were no relevant CPGs in the literature, related articles in Persian and English languages were extracted. Each article along with its level of evidence was summarized. Additionally, hand search was performed by looking the reference list of each article. Consequently, recommendations were developed considering the clinical benefits and side effects of each therapeutic modality. The recommendations were re-evaluated in terms of customization criteria. All recommendations along with the related evidence were scored from 1 to 9 by experts from all medical universities of Iran. The level of agreement among the experts was evaluated by analyzing the given scores. Results: The agreement was achieved for all recommendations. The experts suggested a number of minor modifications which were applied to the recommendations. Finally, CPGs were developed with 98 recommendations under three major domains including prevention of injury, diagnosis and management of the acute and delayed-onset mustard gas ocular injuries. Conclusion: Considering the lack of CPGs for the prevention, diagnosis, and management of mustard gas-induced keratitis, these recommendations would be useful to prevent the serious ocular complications of mustard gas and standardize eye care services to the affected individuals.

Wound healing occurs due to a proliferation of stem cells capable of restoring the injured tissue. The ability of adult stem cells to repair tissue is dependent upon the intrinsic ability of tissues to proliferate. The amazing capacity of embryonic stem cells to give rise to virtually any type of tissue has intensified the search for similar cell lineage in adults to treat various diseases including cardiovascular diseases. The ability to convert adult stem cells into pluripotent cells that resemble embryonic cells, and to transplant those in the desired organ for regenerative therapy is very attractive, and may offer the possibility of treating harmful disease-causing mutations. The race is on to find the best cells for treatment of cardiovascular disease. There is a need for the ideal stem cell, delivery strategies, myocardial retention, and time of administration in the ideal patient population. There are multiple modes of stem cell delivery to the heart with different cell retention rates that vary depending upon method and site of injection, such as intra coronary, intramyocardial or via coronary sinus. While there are crucial issues such as retention of stem cells, microvascular plugging, biodistribution, homing to myocardium, and various proapoptotic factors in the ischemic myocardium, the regenerative potential of stem cells offers an enormous impact on clinical applications in the management of cardiovascular diseases.Keywords: stem cell therapy, stem cell delivery, cardiovascular diseases, myocardial infarction, cardiomyopathy

Results The total mortality rate of injuries was 48.45 per 100000, and the age - standardized mortality rate was 46. 72 per 100000. The proportion of injury deaths was accounted for 6. 37% in total deaths, ranked the fifth in the all - death - causes, and the second in the PYLL. Age - specific mortality rates of injuries was increased with age after 35 years, and the highest mortality rate was seen in the age group of 80 years; and 84. 23% of injury occurred between ages 35 - 85 years. Average years of life lost ( AYLL) was 17. 55

    Pyrazole can induce CYP2E1 and 2A5, which produce reactive oxygen species (ROS). Nuclear factor erythroid 2-related factor 2 (Nrf2) regulates important antioxidant enzymes to remove ROS. In this study, we applied Nrf2 knockout mice to test the hypothesis that pyrazole will cause hepatotoxicity and elevate oxidative stress to a greater extent in Nrf2 knockout mice compared to wild type mice. Pyrazole induced severe oxidative liver damage in Nrf2 knockout mice but not in wild type mice. Activities and levels of CYP2E1 and 2A5 were elevated by pyrazole in the wild type mice but not in the Nrf2 knockout mice. However, expression or activity of Nrf2-regulated antioxidant enzymes, such as gamma-glutamylcysteine synthetase (GCS), heme oxygenase-1 (HO-1) and glutathione-S-transferase (GST), were upregulated in the pyrazole-treated wild type mice, but to a lesser extent or not at all in the pyrazole-treated Nrf2 knockout mice. Treatment with antioxidants such as vitamin C or S-adenosyl-l-methionine (SAM) or an inhibitor of iNOS prevented the pyrazole-induced oxidative liver damage, thus validating the role of oxidative/nitrosative stress in the pyrazole induced liver injury to the Nrf2 knockout mice. In summary, even though ROS-producing CYP2E1/2A5 were not elevated by pyrazole, impaired antioxidant capacity resulting from Nrf2 deficiency appear to be sufficient to promote pyrazole-induced oxidative liver injury.

    Immigration has increased drastically to the point of becoming an ordinary structure of our society. Once in Italy, the immigrant's health is compromised rapidly due to a series of conditions and illnesses that exist in our country: lack of work, inadequate salary, inappropriate residence, lacking family support, climate changes, nutritional differences. Cardiovascular illnesses represent 7.6% of the diseases of the immigrants, and cause 36.6% of deaths. The risk factors that affect the genesis of cardiovascular diseases include: subjective factors (age, ethnic group), environmental, nutritional and pathological (arterial hypertension, AIDS, tuberculosis, alcohol). The challenge for our time is to design a new solidarity model to promote cultural and social integration in order to meet the multiethnical and multiracial needs of western society. This model should permit reconsideration of doctor-patient relationship in order to build a real intercultural society.

    目的:通过临床资料的分析,探讨腮腺导管损伤手术治疗失败的原因.方法:33例因外伤而造成腮腺导管断离的病例,在行清创缝合术中,游离减张导管断端并用塑料管做支架进行导管吻合手术.其中8例初次手术失败,导管断裂,形成导管瘘,进行了第二次手术.结果:8例失败病例,均经Ⅱ期导管端端吻合术后治愈.结论:在施行吻合术中,导管两断端是否充分显露,游离减张是手术成败的关键,术后适当加压包扎,使用促涎液分泌的药物,抗感染,加强口腔护理,防止塑料管滑脱和过早拔除也是减少手术失败的重要因素.%Objective:To discuss the reasons of treatment failure of parotid duct injury. Methods: 33 traumatic parotid duct cases were reviewed. After debridement, the fistula was closed under local anesthesia, which primary repair was located over a catheter. And then the duct was united with interrupted sutures. A dressing and a pressure bandage were applied. Results: 8 cases were not successful, whose parotid duct fistula was re-operated, and then fistulas were eliminated. Conclusion: Fully exposure and small tension is the key factor in debridement and suturing. Appropriate pressure, adequate parotid secretion, antibiotics, special mouth care, and time of pulling catheter are very important after operation.

    Long-term neurological damage as a result of head trauma while playing sports is a major concern for football athletes today. Repetitive concussions have been linked to many neurological disorders. Recently, it has been reported that repetitive subconcussive events can be a significant source of accrued damage. Since football athletes can experience hundreds of subconcussive hits during a single season, it is of utmost importance to understand their effect on brain health in the short and long term. In this study, resting-state functional magnetic resonance imaging (rs-fMRI) was used to study changes in the default mode network (DMN) after repetitive subconcussive mild traumatic brain injury. Twenty-two high school American football athletes, clinically asymptomatic, were scanned using the rs-fMRI for a single season. Baseline scans were acquired before the start of the season, and follow-up scans were obtained during and after the season to track the potential changes in the DMN as a result of experienced trauma. Ten noncollision-sport athletes were scanned over two sessions as controls. Overall, football athletes had significantly different functional connectivity measures than controls for most of the year. The presence of this deviation of football athletes from their healthy peers even before the start of the season suggests a neurological change that has accumulated over the years of playing the sport. Football athletes also demonstrate short-term changes relative to their own baseline at the start of the season. Football athletes exhibited hyperconnectivity in the DMN compared to controls for most of the sessions, which indicates that, despite the absence of symptoms typically associated with concussion, the repetitive trauma accrued produced long-term brain changes compared to their healthy peers.

  5. Rho kinases in cardiovascular physiology and pathophysiology: the effect of fasudil.

    Shi, Jianjian; Wei, Lei

    2013-10-01

    Rho kinase (ROCK) is a major downstream effector of the small GTPase RhoA. ROCK family, consisting of ROCK1 and ROCK2, plays central roles in the organization of actin cytoskeleton and is involved in a wide range of fundamental cellular functions, such as contraction, adhesion, migration, proliferation, and apoptosis. Due to the discovery of effective inhibitors, such as fasudil and Y27632, the biological roles of ROCK have been extensively explored with particular attention on the cardiovascular system. In many preclinical models of cardiovascular diseases, including vasospasm, arteriosclerosis, hypertension, pulmonary hypertension, stroke, ischemia-reperfusion injury, and heart failure, ROCK inhibitors have shown a remarkable efficacy in reducing vascular smooth muscle cell hypercontraction, endothelial dysfunction, inflammatory cell recruitment, vascular remodeling, and cardiac remodeling. Moreover, fasudil has been used in the clinical trials of several cardiovascular diseases. The continuing utilization of available pharmacological inhibitors and the development of more potent or isoform-selective inhibitors in ROCK signaling research and in treating human diseases are escalating. In this review, we discuss the recent molecular, cellular, animal, and clinical studies with a focus on the current understanding of ROCK signaling in cardiovascular physiology and diseases. We particularly note that emerging evidence suggests that selective targeting ROCK isoform based on the disease pathophysiology may represent a novel therapeutic approach for the disease treatment including cardiovascular diseases.

    Osteoporosis and cardiovascular disease were long viewed as independent of each other. However, numerous epidemiological studies, which are discussed in the first part of this review, have provided incontrovertible evidence of a link. Thus, the risk of coronary artery disease and stroke is higher in patients with a history of osteoporotic fracture or low bone mineral density than in non-osteoporotic patients. In the other direction, patients with cardiovascular disease are at higher risk for bone loss and osteoporotic fracture. The link between osteoporosis and cardiovascular disease is due in part to shared conventional risk factors such as estrogen deprivation in women, smoking, low physical activity, and diabetes. In addition, atheroma plaque calcification involves cytokines and growth factors that also play a role in bone turnover, including proinflammatory cytokines (IL-6 and TNFα), osteoprotegerin, sclerostin, matrix GLA protein, and FGF-23. Several recent studies have provided support for these pathophysiological hypotheses. Thus, elevation of osteoprotegerin, sclerostin, or FGF-23 levels may explain and predict the occurrence of both osteoporotic fractures and cardiovascular events. The association between osteoporosis and cardiovascular disease found in most epidemiological and pathophysiological studies suggests a need for evaluating potential benefits from routine bone absorptiometry and osteoporotic fracture detection in patients with cardiovascular disease and from exercise testing and arterial Doppler imaging in patients with osteoporosis.

    It was the purpose of this review to document the range, incidence, location and mechanism of injury occurring in the sport of rugby league. Rugby league is a collision sport played in Europe and the Pacific regions including Australia. The sport is well established and has competitions ranging from junior to elite professional. Due to the contact nature of the game, injury is relatively common. The most common injuries are musculotendinous in nature and afflict the lower limb more frequently than elsewhere. Despite the high incidence of minor (sprains/strains) to moderate musculoskeletal injury (fracture, ligament and joint injury) and minor head injuries such as lacerations, nasal fractures and concussions, rare more serious spinal cord and other injuries causing death have also been recorded. The literature on rugby league injury is small but growing and suffers from a lack of consistent definition of what an injury is, thereby causing variability in the nature and incidence/prevalence of injury. Information is lacking on the injury profiles of different age groups. Importantly, there has been little attempt to establish a coordinated injury surveillance program in rugby league in the junior or professional levels. The implementation of such programs would require a universal definition of injury and a focus on important events and competitions. The implementation could provide important information in the identification and prevention of risk factors for injury.

  8. Stress and atherosclerotic cardiovascular disease.

    Recent major advances in medical science have introduced a wide variety of treatments against atherosclerosis-based cardiovascular diseases, which has led to a significant reduction in mortality associated with these diseases. However, atherosclerosis-based cardiovascular disease remains a leading cause of death. Furthermore, progress in medical science has demonstrated the pathogenesis of cardiovascular disease to be complicated, with a wide variety of underlying factors. Among these factors, stress is thought to be pivotal. Several types of stress are involved in the development of cardiovascular disease, including oxidative stress, mental stress, hemodynamic stress and social stress. Accumulating evidence indicates that traditional risk factors for atherosclerosis, including diabetes, hyperlipidemia, hypertension and smoking, induce oxidative stress in the vasculature. Oxidative stress is implicated in the pathogenesis of endothelial dysfunction, atherogenesis, hypertension and remodeling of blood vessels. Meanwhile, mental stress is a well-known major contributor to the development of cardiovascular disease. The cardiovascular system is constantly exposed to hemodynamic stress by the blood flow and/or pulsation, and hemodynamic stress exerts profound effects on the biology of vascular cells and cardiomyocytes. In addition, social stress, such as that due to a lack of social support, poverty or living alone, has a negative impact on the incidence of cardiovascular disease. Furthermore, there are interactions between mental, oxidative and hemodynamic stress. The production of reactive oxygen species is increased under high levels of mental stress in close association with oxidative stress. These stress responses and their interactions play central roles in the pathogenesis of atherosclerosis-based cardiovascular disease. Accordingly, the pathophysiological and clinical implications of stress are discussed in this article.

  9. The Role of Oxidative Stress in Myocardial Ischemia and Reperfusion Injury and Remodeling: Revisited

    Full Text Available Oxidative and reductive stress are dual dynamic phases experienced by the cells undergoing adaptation towards endogenous or exogenous noxious stimulus. The former arises due to the imbalance between the reactive oxygen species production and antioxidant defenses, while the latter is due to the aberrant increase in the reducing equivalents. Mitochondrial malfunction is the common denominator arising from the aberrant functioning of the rheostat that maintains the homeostasis between oxidative and reductive stress. Recent experimental evidences suggest that the maladaptation during oxidative stress could play a pivotal role in the pathophysiology of major cardiovascular diseases such as myocardial infraction, atherosclerosis, and diabetic cardiovascular complications. In this review we have discussed the role of oxidative and reductive stress pathways in the pathogenesis of myocardial ischemia/reperfusion injury and diabetic cardiomyopathy (DCM. Furthermore, we have provided impetus for the development of subcellular organelle targeted antioxidant drug therapy for thwarting the deterioration of the failing myocardium in the aforementioned cardiovascular conditions.

    Severe psoriasis has been associated with increase cardiovascular mortality, due to a higher prevalence of traditional cardiovascular risk factors and premature atherosclerosis, as a consequence of its systemic inflammation. Recently, it has been estimated that severe psoriasis may confer an increased 6.2% on long-term risk of cardiovascular disease based on Framingham Risk Score, which can have practical implications in the treatment of cardiovascular risk factors and primary prevention of cardiovascular disease, as treatment guidelines account for the risk of cardiovascular disease in treatment goals. The aim of this study was to analyze the influence of the attributable risk of severe psoriasis on long-term risk of cardiovascular disease and its implication on the correct treatment of cardiovascular risk factors and primary prevention of cardiovascular disease on a real-world cohort of patients. One hundred severe psoriasis patients without psoriatic arthritis or previous cardiovascular disease were evaluated and it was found that more than half of the patients were reclassified to a higher cardiovascular risk category with important clinical implications on the correct management of their cardiovascular risk factors and primary prevention of cardiovascular disease, as a considerable proportion of patients with hypertension, hypercholesterolemia and coronary heart disease equivalent risk were not being correctly managed.

Experience in managing such injuries is limited due to their rarity. The mainstay of management revolves around establishing and maintaining a patent airway and integrity of the spine. Here we document a case of a 25 year old male who met with a Road traffic accident while driving a motorbike and sustained a clear cut linear wound on the right side of the neck with minimal airleak due to the helmet clip. On exploration, he was found to have massive epiglottic edema, mucosal abrasions, lacerations and a thyroid cartilage fracture.

    Sleep is a natural periodic suspension of consciousness during which processes of rest and restoration occur. The cognitive, reparative and regenerative accompaniments of sleep appear to be essential for maintenance of health and homeostasis. This brief overview will examine the cardiovascular responses to normal and disordered sleep, and their physiologic and pathologic implications. In the past, sleep was believed to be a passive state. The tableau of sleep as it unfolds is anything but a passive process. The brain's activity is as complex as wakefulness, never "resting" during sleep. Following the demise of the 'passive theory of sleep' (the reticular activating system is fatigued during the waking day and hence becomes inactive), there arose the 'active theory of sleep' (sleep is due to an active general inhibition of the brain) (1). Hess demonstrated the active nature of sleep in cats, inducing "physiological sleep" with electrical stimulation of the diencephalon (2). Classical experiments of transection of the cat brainstem (3) at midpontine level inhibited sleep completely, implying that centers below this level were involved in the induction of sleep (1, 4). For the first time, measurement of sleep depth without awakening the sleeper using the electroencephalogram (EEG) was demonstrated in animals by Caton and in humans, by Berger (1). This was soon followed by discovery of the rapid eye movement sleep periods (REM) by Aserinski and Kleitman (5), demonstration of periodical sleep cycles and their association with REM sleep (6, 7). Multiple studies and steady discoveries (4) made polysomnography, with its ability to perform simultaneous whole night recordings of EEG, electromyogram (EMG), and electrooculogram (EOC), a major diagnostic tool in study of sleep disorders. This facility has been of further critical importance in allowing evaluation of the interaction between sleep and changes in hemodynamics and autonomic cardiovascular control. Consequently the

    1st, 1999 to November 30th, 2000. The sample included 696 children and adolescents hospitalized for injuries, ages ranging from 0 to 19 years old. The International Statistical Classification of Diseases and Related Health Problems (10th version was used as a parameter to classify the types of injuries and sites where they happened. RESULTS: The injuries represented 9.9% of children and adolescents' hospitalizations, of which, 69.7% were male patients. As for the informants' opinion about causes of injuries, 57.2% attributed then to human failure, 18% believed they were due to fate and 12.7% did not know how to express their opinions. Only 23.1% of the informants had received previous orientation about prevention and the main sources were media, school and work place. A total of 31.9% of the events took place at home. Transportation injuries caused 34.5% of hospitalizations; falls, 33.2%; exposure to inanimate mechanical forces, 9%; contact with poisonous animals, 5.2%; aggression, 5%; burns, 4.9%; exposure to animated mechanical forces, 3.3%; intoxication, 2.3%; and other types, 2.6%. CONCLUSIONS: Males were more affected than females. Only a low percentage of the informants had received previous orientation about injury prevention. The most affected age group was between 15 and 19 years. Transportation accidents and falls were the most frequent causes of injuries.

    segment under the bridge has been discussed by the scientific community. OBJECTIVE: To compare ultrastructural muscle tissue of myocardial bridge and the ventricular wall; to analyze the degree of injury to the tunica intima of the arterial segments, and look for possible changes that may precede or initiate the process of atherosclerotic lesions. METHODS: Forty Canchim bovine hearts were studied regarding alterations of the tunica intima from coronary arteries on the different myocardial bridge segments. For the microscopic examination, hematoxylin-eosin and fuchsin-resorcin staining following conventional microscope techniques were made. For the electronic microscopic examination, myocardial Bridge segments from twelve Canchim bovine hearts were collected from the ventricle wall and coronary artery and were processed according to conventional techniques. RESULTS: In the light microscopy, a higher frequency of lesions on prepontine and postpontine segments of the tunica intima was observed, compared to the pontine segment. Tunica intima thickenings were followed by a disarrangement on the internal elastic limitant lamina. These cells often presented their cytoplasmas engorged by lipidic drops, making up the so-called foam cells. Electronic microscopy revealed that the muscular fibers of the myocardial bridge are usually joined in a straight and smooth way presenting lateral branches with a greater number of mitochondria in the ventricular muscle than in the bridge. CONCLUSION: There are few differences between the muscle tissues studied; intimae lesions are less frequent in pontine regions compared to pre and post-pontine regions.

    2013-01-01

    In order to study if tricyclic antidepressant drugs (TCA) in therapeutic doses increase the risk of death due to cardiovascular causes, the relative mortality from cardiovascular diseases was studied in two large groups of first hospitalized manic-depressive patients, one from the TCA era......, the other from the period just before the introduction of TCA. Both groups were selected from the Danish Psychiatric Central Register and followed for an average of 4.5 years. Among 2662 manic-depressive men hospitalized between 1969 and 1976, the relative cardiovascular mortality was 1.53 compared...... to the general population. Among 1133 such cases admitted between 1950 and 1956, the rate was 1.87. Our findings do not support the hypothesis that TCA contribute to the cardiovascular mortality in manic-depressives and even support suggestions that TCA treatment may lower the risk of death by cardiovascular...

    A: The Schlichtungsstelle (expert panel for alternative dispute resolution) of Northern Germany, in 2001, decided on 2620 malpractice claims; 233 of these were related to the treatment of cardiovascular disorders, coronary and venous diseases being the most common. The physicians involved in these disputes represented 18 (sub-)specialities. Complaints related to procedures were the ones most frequently submitted by the patients, followed by those concerning diagnostics. Negligence was found to be present in 37% of the cases, the highest proportion being due to mistakes of diagnosis, followed by organisational and system-related mistakes. Medical negligence as the cause of injury was assumed in 46/233 (20%) of the cases, the injuries being serious in 18 and fatal in 6 of the 46 patients. Negligent and non-negligent iatrogenic injuries combined, amounted to 132/233 (57%) of the "cardiovascular" panel cases. B: From 1992 to 2001, we collected 165 panel cases involving cardiologists and 3 involving angiologists. In most of these the underlying disease was coronary, but in 14 cases the underlying disorder was psychosomatic. 35% of the complaints submittted by the patients were about invasive procedures. 12% of the instances of negligence determined in the panel proceedings were due to procedural mistakes, whereas 47% were due to mistakes related to indication and to the monitoring of the patients after procedures. Negligent iatrogenic injury was assumed in 27%, non-negligent iatrogenic injury in another 53% of the cases, so that the total of iatrogenic injuries amounted to 80% of the "cardio-angiologists" panel cases. 19/168 (11%) patients died from iatrogenic injuries. Organization and coordination among medical persons and institutions treating patients need improvement. A considerable number of disputes and claims seems to be initiated and caused by deficits in doctor-patient-communication. Attempts at reducing negligence and adverse events should center around those

    Cardiovascular disease is rare in premenopausal women compared with men in similar age groups. After menopause, however, the gender difference in cardiovascular disease diminishes, and there is an increased incidence of coronary risk and events in women. Although a number of factors contribute to the development of atherosclerotic disease in women, estrogen replacement therapy reduces cardiovascular risk. Potential molecular mechanisms for the antiatherosclerotic effects of estrogen are discussed here. It is proposed that lipid-lowering and antioxidant properties of estrogen synergize to elicit the observed vasoprotective effects. These processes are discussed in the context of balloon-injury models and hypercholesterolemia. (Trends Cardiovasc Med 1997;7:94-100). © 1997, Elsevier Science Inc.

    Full Text Available Cardiolipin (CL, the signature phospholipid of mitochondrial membranes, is crucial for both mitochondrial function and cellular processes outside of the mitochondria. The importance of CL in cardiovascular health is underscored by the life-threatening genetic disorder Barth syndrome (BTHS, which manifests clinically as cardiomyopathy, skeletal myopathy, neutropenia, and growth retardation. BTHS is caused by mutations in the gene encoding tafazzin, the transacylase that carries out the second CL remodeling step. In addition to BTHS, CL is linked to other cardiovascular diseases (CVDs, including cardiomyopathy, atherosclerosis, myocardial ischemia-reperfusion injury, heart failure, and Tangier disease. The link between CL and CVD may possibly be explained by the physiological roles of CL in pathways that are cardioprotective, including mitochondrial bioenergetics, autophagy/mitophagy, and mitogen activated protein kinase (MAPK pathways. In this review, we focus on the role of CL in the pathogenesis of CVD as well as the molecular mechanisms that may link CL functions to cardiovascular health.

With more than 5 million deaths every year, violence and injuries account for 9% of global mortality, as many deaths as from HIV, Malaria and Tuberculosis combined. Eight of the 15 leading causes of death for people ages 15 to 29 years are injury-related: road traffic injuries, suicides, homicides, drowning, burns, war injuries, poisonings and falls. For every death due to war, there are three deaths due to homicide and five deaths due to suicide. However, most violence happens to people behind closed doors and results not in death, but often in years of physical and emotional suffering [1]. Injuries can be classified by intent: unintentional or intentional. Traffic injuries, fire-related injuries, falls, drowning, and poisonings are most often classified as unintentional injuries; injuries due to assault, selfinflicted violence such as suicide, and war are classified as intentional injuries, or violence. Worldwide, governments and public and private partners are increasingly aware of the strains that unintentional injuries and violence place on societies. In response they are strengthening data collection systems, improving services for victims and survivors, and increasing prevention efforts [1].

  8. MUSCLE INJURIES IN ATHLETES.

    This article had the aim of demonstrating the physiology, diagnosis and treatment of muscle injuries, focusing on athletes and their demands and expectations. Muscle injuries are among the most common complaints in orthopedic practice, occurring both among athletes and among non-athletes. These injuries present a challenge for specialists, due to the slow recovery, during which time athletes are unable to take part in training and competitions, and due to frequent sequelae and recurrences of the injuries. Most muscle injuries (between 10% and 55% of all injuries) occur during sports activities. The muscles most commonly affected are the ischiotibial, quadriceps and gastrocnemius. These muscles go across two joints and are more subject to acceleration and deceleration forces. The treatment for muscle injuries varies from conservative treatment to surgery. New procedures are being used, like the hyperbaric chamber and the use of growth factors. However, there is still a high rate of injury recurrence. Muscle injury continues to be a topic of much controversy. New treatments are being researched and developed, but prevention through muscle strengthening, stretching exercises and muscle balance continues to be the best "treatment".

  11. Oxidative stress and cardiovascular complications in polycystic ovarian syndrome.

    Hyderali, Barkath Nisha; Mala, Kanchana

    2015-08-01

    Polycystic ovarian syndrome (PCOS) is a complex endocrine condition which is associated with metabolic and cardiovascular complications. It is elevated to a metabolic disorder with significant long term health ramification due to the high prevalence of insulin resistance (IR), impaired glucose tolerance, type 2 diabetes (T2D), dyslipidemia and numerous cardiovascular risk factors in PCOS women. This article concentrates on the recent developments in the regulation of oxidative stress (OS) in PCOS and on the association between PCOS and CVD outcomes. The prognostic events that define the severity of PCOS and involvement of cardiovascular risk in PCOS include endothelial dysfunction (ED) and impaired cardiac structure. Fact is that, in PCOS women, the circulating biomarkers of OS are in abnormal levels that are independent of overweight, which depicts the participation of OS in the pathophysiology of this common derangement. In addition, hyperglycemia (HG) per se, promotes reactive oxygen species (ROS) generation in PCOS. When the destructive ROS outbalances the concentration of physiological antioxidants, OS occurs. The resultant OS, directly stimulates hyperandrogenism and causes extensive cellular injury, DNA damage and/or cell apoptosis. To further the burden, the total serum antioxidant level in PCOS women is compromised, which diminishes the body's defense against an oxidative milieu. Thus, it is evident that OS regulates several cellular mechanisms in PCOS. Improving our understanding about the regulation of OS, critical role of ROS and protein biomarkers in PCOS should lead to novel therapeutic strategies in addressing PCOS-induced CVD. Besides, it is possible that the beneficial effects of dietary or therapeutic antioxidants have significant clinical relevance in PCOS.

  12. Dietary Nitrate, Nitric Oxide, and Cardiovascular Health.

    Science.gov (United States)

    Bondonno, Catherine P; Croft, Kevin D; Hodgson, Jonathan M

    2016-09-09

    Emerging evidence strongly suggests that dietary nitrate, derived in the diet primarily from vegetables, could contribute to cardiovascular health via effects on nitric oxide (NO) status. NO plays an essential role in cardiovascular health. It is produced via the classical L-arginine-NO-synthase pathway and the recently discovered enterosalivary nitrate-nitrite-NO pathway. The discovery of this alternate pathway has highlighted dietary nitrate as a candidate for the cardioprotective effect of a diet rich in fruit and vegetables. Clinical trials with dietary nitrate have observed improvements in blood pressure, endothelial function, ischemia-reperfusion injury, arterial stiffness, platelet function, and exercise performance with a concomitant augmentation of markers of NO status. While these results are indicative of cardiovascular benefits with dietary nitrate intake, there is still a lingering concern about nitrate in relation to methemoglobinemia, cancer, and cardiovascular disease. It is the purpose of this review to present an overview of NO and its critical role in cardiovascular health; to detail the observed vascular benefits of dietary nitrate intake through effects on NO status as well as to discuss the controversy surrounding the possible toxic effects of nitrate.

    2013-05-01

    The cardiovascular system of a premenopausal woman is prepared to adapt to the challenges of increased cardiac output and work load that accompany pregnancy. Thus, it is tempting to speculate whether enhanced adaptability of the female cardiovascular system might be advantageous under conditions that promote cardiovascular disease. In support of this concept, 17β-estradiol as the major female sex hormone has been shown to confer protective cardiovascular effects in experimental studies. Mechanistically, these have been partially linked to the prevention and protection against oxidative stress. Current evidence indicates that estrogens attenuate oxidative stress at two levels: first, by preventing generation of reactive oxygen species (ROS) and, second, by scavenging ROS in the myocardium and in the vasculature. The purpose of this review is to give an overview on current concepts on conditions and mechanisms by which estrogens protect the cardiovascular system against ROS-mediated cellular injury.

    CHEN Hai-bin; King H YANG; WANG Zheng-guo

    2009-01-01

    Despite a large number of rear-end collisions on the road and a high frequency of whiplash injuries reported, the mechanism of whiplash injuries is not completely understood. One of the reasons is that the injury is not necessarily accompanied by obvious tissue damage detectable by X-ray or MRI. An extensive series of biomechanics studies, including injury epidemiology, neck kinematics,facet capsule ligament mechanics, injury mechanisms and injury criteria, were undertaken to help elucidate these whiplash injury mechanisms and gain a better understanding of cervical facet pain. These studies provide the following evidences to help explain the mechanisms of the whiplash injury: (1) Whiplash injuries are generally considered to be a soft tissue injury of the neck with symptoms such as neck pain and stiffness, shoulder weakness, dizziness, headache and memory loss, etc. (2) Based on kinematical studies on the cadaver and volunteers, there are three distinct periods that have the potential to cause injury to the neck. In the first stage, flexural deformation of the neck is observed along with a loss of cervical lordosis; in the second stage, the cervical spine assumes an S-shaped curve as the lower vertebrae begin to extend and gradually cause the upper vertebrae to extend; during the final stage, the entire neck is extended due to the extension moments at both ends. (3)The in vivo environment afforded by rodent models of injury offers particular utility for linking mechanics, nociception and behavioral outcomes. Experimental findings have examined strains across the facet joint as a mechanism of whiplash injury, and suggested a capsular strain threshold or a vertebral distraction threshold for whiplash-related injury,potentially producing neck pain. (4) Injuries to the facet capsule region of the neck are a major source of post-crash pain. There are several hypotheses on how whiplash-associated injury may occur and three of these injuries are related to strains within

    2016-03-10

    The initial step in developing injury prevention strategies is to establish the epidemiology of injury. However there has been no published research on injury in Gaelic handball. This study describes the epidemiology of injury in 75 Gaelic handball players utilising a retrospective questionnaire. 88% of participants reported one or more injuries. Injuries to the upper limb were prevalent (52.9%), followed by the lower limb (30.3%). The shoulder (17.6%), finger (10.5%) and ankle (9.8%) were the primary sites of injury. Injuries occurred most frequently in December (9.7%), January (9.7%), February (9.7%) and November (8.7%). Injuries predominantly occurred during games (82.4%). Injuries were primarily severe (54.7%), with 14.6% of participants admitted to hospital due to injury. Given that this is the only study on Gaelic handball to date, prospective epidemiological studies and further research on injury prevention strategies are necessary.

    cholesterol might not cause cardiovascular disease as originally thought has now generated renewed interest in raised concentrations of triglycerides. This renewed interest has also been driven by epidemiological and genetic evidence supporting raised triglycerides, remnant cholesterol, or triglyceride......-rich lipoproteins as an additional cause of cardiovascular disease and all-cause mortality. Triglycerides can be measured in the non-fasting or fasting states, with concentrations of 2-10 mmol/L conferring increased risk of cardiovascular disease, and concentrations greater than 10 mmol/L conferring increased risk...... of acute pancreatitis and possibly cardiovascular disease. Although randomised trials showing cardiovascular benefit of triglyceride reduction are scarce, new triglyceride-lowering drugs are being developed, and large-scale trials have been initiated that will hopefully provide conclusive evidence...

    The number of patients suffering from cardiovascular diseases increases unproportionally high with the increase of the human population and aging, leading to very high expenses in the public health system. Therefore, the challenge of cardiovascular physics is to develop high-sophisticated methods which are able to, on the one hand, supplement and replace expensive medical devices and, on the other hand, improve the medical diagnostics with decreasing the patient's risk. Cardiovascular physics-which interconnects medicine, physics, biology, engineering, and mathematics-is based on interdisciplinary collaboration of specialists from the above scientific fields and attempts to gain deeper insights into pathophysiology and treatment options. This paper summarizes advances in cardiovascular physics with emphasis on a workshop held in Bad Honnef, Germany, in May 2005. The meeting attracted an interdisciplinary audience and led to a number of papers covering the main research fields of cardiovascular physics, including data analysis, modeling, and medical application. The variety of problems addressed by this issue underlines the complexity of the cardiovascular system. It could be demonstrated in this Focus Issue, that data analyses and modeling methods from cardiovascular physics have the ability to lead to significant improvements in different medical fields. Consequently, this Focus Issue of Chaos is a status report that may invite all interested readers to join the community and find competent discussion and cooperation partners.

    Edible oils form an essential part of the modern diet. These oils play a role as an energy source, and provide the diet with many beneficial micronutrients. Although a popular conception may be that fat should be avoided, certain edible oils as a dietary supplement may play an important role in the improvement of cardiovascular health. CVD has become one of the leading causes of death worldwide. Dietary supplementation with different oils may have beneficial effects on cardiovascular health. While olive oil and sunflower-seed oil are known to reduce serum cholesterol, fish oil has become well known for reducing potentially fatal cardiac arrhythmias. Recently, red palm oil research has shown beneficial effects on cardiac recovery from ischaemia-reperfusion injury. It is clear that dietary supplementation with edible oils may play a vital role in reducing the mortality rate due to heart disease. The specific benefits and disadvantages of these oils should, however, be explored in greater depth. The present review will attempt to identify the benefits and shortcomings of four popular edible oils, namely olive oil, sunflower-seed oil, fish oil and palm oil. Additionally the present review will aim to reveal potential areas of research which could further enhance our understanding of the effects of edible oils on cardiovascular health.

  4. Cardiovascular comorbiditiy in psoriasis

    Full Text Available The chronic inflammatory nature of psoriasis is also thought to predispose patients to other diseases with an inflammatory component, the most notable being cardiovascular and metabolic (cardiometabolite disorders. This concept is supported by studies showing that psoriasis is associated with cardiovascular risk factors like diabetes, obesity, hypertension, dyslipidemia, smoking and diseases including MI. Given the increased prevalence of cardiovascular co morbidities in patients, dermatologists treating psoriasis need to approach the disease as a potentially multisystem disorder and must alert these patients to the potentially negative effects of their disease.

    Urocortin and other hypothalamus corticotropin-releasing factor (CRF) polypeptides play biologically diverse roles in the stress, cardiovascular and inflammatory responses by acting on central and peripheral CRF receptors.Urocortin shows a significantly high sequence homology to CRF, and the concurrent expression of type-2 CRF (CRF2) receptors with urocortin in the heart suggests that urocortin may play a physiological role in the cardiac function. Urocortin is thought to be the endogenous agonist producing the cardiovascular actions previously attributed to CRF. This review highlights the current novel findings on the molecular and cellular mechanisms by which urocortin may exert its cardiovascular protective action.

  6. Injuries in classical ballet

    2008-06-01

    Full Text Available This study aimed to elucidate what injuries are most likely to occur due to classical ballet practice. The research used national and international bibliography. The bibliography analysis indicated that technical and esthetical demands lead to a practice of non-anatomical movements, causing the ballet dancer to suffer from a number of associated lesions. Most of the injuries are caused by technical mistakes and wrong training. Troubles in children are usually due to trying to force external rotation at hip level and to undue use of point ballet slippers. The commonest lesions are in feet and ankles, followed by knees and hips. The rarest ones are in the upper limbs. These injuries are caused by exercise excess, by repetitions always in the same side and by wrong and early use of point slippers. The study reached the conclusion that incorrect application of classical ballet technique predisposes the dancers to characteristic injuries.

    It is estimated that at least 80% of patients with cardiovascular disease (CVD) have conventional risk factors and optimization of these risk factors can reduce morbidity and mortality due to this disease considerably. Contemporary women have increased burden of some of these risk factors such as obesity, metabolic syndrome and smoking. Turkish women have a worse CV risk profile than Turkish men in some aspects. Risk stratification systems such as Framingham have a tendency of underestimating the risk in women. Coronary artery disease remains in vessel wall for a longer period of time in women; therefore obstructive disease appear later in their lifespan necessitating risk stratification systems for estimating their lifetime risk.

    The traditional oral pharmacological therapy for type 2 diabetes mellitus (T2DM) has been based on the prescription of metformin, a biguanide, as first line antihyperglycemic agent world over. It has been demonstrated that after 3 years of treatment, approximately 50% of diabetic patients could achieve acceptable glucose levels with monotherapy; but by 9 years this had declined to only 25%. Therefore, the implementation of a combined pharmacological therapy acting via different pathways becomes necessary, and its combination with a compound of the sulfonylurea group was along decades the most frequently employed prescription in routine clinical practice. Meglitinides, glitazones and alpha-glucosidase inhibitors were subsequently developed, but the five mentioned groups of oral antihyperglycemic agents are associated with variable degrees of undesirable or even severe cardiovascular events. The gliptins-also called dipeptidyl peptidase 4 (DPP4) inhibitors--are an additional group of antidiabetic compounds with increasing clinical use. We review the status of the gliptins with emphasis on their capabilities to positively or negatively affect the cardiovascular system, and their potential involvement in major adverse cardiovascular events (MACE). Alogliptin, anagliptin, linagliptin, saxagliptin, sitagliptin, teneligliptin and vildagliptin are the compounds currently in clinical use. Regardless differences in chemical structure and metabolic pathways, gliptins as a group exert favorable changes in experimental models. These changes, as an almost general rule, include improved endothelial function, reduction of inflammatory markers, oxidative stress ischemia/reperfusion injury and atherogenesis. In addition, increased adiponectin levels and modest decreases in lipidemia and blood pressure were reported. In clinical settings, several trials--notably the longer one, employing sitagliptin, with a mean follow-up period of 3 years--did not show an increased risk for ischemic

    2009-01-01

    The endoplasmic reticulum (ER) serves several important functions, mainly post-translational modification, folding and assembly of newly synthesized secretary proteins, synthesizing lipids and cellular calcium storage. Various factors can disrupt ER homeostasis and disturb its functions, which leads to the accumulation of unfolded and misfolded proteins and to potential cellular dysfunction and pathological consequences, collectively termed ER stress. Recent progress suggests that ER stress plays a key role in the immune response, diabetes, tumor growth, and some neurodegenerative diseases. In particular, ER stress is involved in several processes of cardiovascular diseases, such as ischemia/reperfusion injury, cardiomyopathy, cardiac hypertrophy, heart failure, and atherosclerosis. Further research on the relation of ER stress to cardiovascular diseases will greatly enhance the understanding of these pathological processes and provide novel avenues to potential therapies.

    Heart failure (HF) is associated with significant morbidity and mortality attributable largely to structural changes in the heart and with associated cardiac dysfunction. Remodeling is defined as alteration of the mass, dimensions, or shape of the heart (termed cardiac or ventricular remodeling) and vessels (vascular remodeling) in response to hemodynamic load and/or cardiovascular injury in association with neurohormonal activation. Remodeling may be described as physiologic or pathologic; alternatively, remodeling may be classified as adaptive or maladaptive. The importance of remodeling as a pathogenic mechanism has been controversial because factors leading to remodeling as well as the remodeling itself may be major determinants of patients' prognosis. The basic mechanisms of cardiovascular remodeling, and especially the roles of microRNAs in HF progression and vascular diseases, will be reviewed here.

    In this paper, a novel approach to modeling and diagnosing the cardiovascular system is introduced. A model exhibits a subset of the dynamics of the cardiovascular behavior of an individual by using a recurrent artificial neural network. Potentially, a model will be incorporated into a cardiovascular diagnostic system. This approach is unique in that each cardiovascular model is developed from physiological measurements of an individual. Any differences between the modeled variables and the variables of an individual at a given time are used for diagnosis. This approach also exploits sensor fusion to optimize the utilization of biomedical sensors. The advantage of sensor fusion has been demonstrated in applications including control and diagnostics of mechanical and chemical processes.

    Fatalities in boxing are most often due to traumatic brain injury that occurs in the ring. In the past 30 years, significant improvements in ringside and medical equipment, safety, and regulations have resulted in a dramatic reduction in the fatality rate. Nonetheless, the rate of boxing-related head injuries, particularly concussions, remains unknown, due in large part to its variability in clinical presentation. Furthermore, the significance of repeat concussions sustained when boxing is just now being understood. In this article, we identify the clinical manifestations, pathophysiology, and management of boxing-related head injuries, and discuss preventive strategies to reduce head injuries sustained by boxers.

Urinary liver-type fatty acid binding protein (L-FABP increases along with tubular hypoxia and may be a detector of systemic circulation injury. The aim of this study was to evaluate the clinical usefulness of detecting increases in urinary L-FABP levels due to administration of CM, as a prognostic biomarker for cardiovascular disease in patients without occurrence of CM-induced nephropathy undergoing cardiac catheterization procedure (CCP. Methods: Retrospective longitudinal analyses of the relationship between urinary L-FABP levels and occurrence of cardiovascular events were performed (n=29. Urinary L-FABP was measured by ELISA before CCP, and at 6, 12, 24, and 48 hours after CCP. Results: Urinary L-FABP levels were significantly higher at 12 hours (P<0.05 and 24 hours (P<0.005 after CCP compared with before CCP, only in the patients with occurrence of cardiovascular events (n=17, but not in those without cardiovascular events (n=12. The parameter with the largest area under the curve (0.816 for predicting the occurrence of cardiovascular events was the change in urinary L-FABP at 24 hours after CCP. The difference in urinary L-FABP levels (ΔL-FABP ≥11.0 µg/g creatinine between before CCP and at 24 hours after CCP was a risk factor for the occurrence of cardiovascular events (hazard ratio, 4.93; 95% confidence interval, 1.27–19.13; P=0.021.

    Cardiovascular disease is the leading cause of death among women. In fact, the cardiovascular disease mortality rate among women exceeds the rate in men. Unfortunately, many minority women are still unaware of the importance of this disease. All women, including those with no history of cardiovascular disease, should have an accurate estimate of the probability of a cardiovascular disease event (death, myocardial infarction, or stroke) usually within the next decade. Such an estimate will help determine if women are candidates for preventive measures and specific therapies such as aspirin. Data from the Framingham Heart Study were used to construct a risk score, which is now widely used; however, other risk scores are available. To prevent cardiovascular disease, women should refrain from smoking, maintain a healthy weight, eat a heart-healthy diet, be physically active, and have normal blood pressure and cholesterol levels. Aspirin can be considered for primary prevention, with expected benefit to prevent ischemic stroke; however, this needs to be balanced against potential bleeding risk. Hormone therapy is no longer recommended due to an increase in adverse events (most consistently seen as increased ischemic stroke risk). Folic acid is also no longer recommended due to lack of benefit.

    The pathogenesis of cardiovascular disease is without any doubt multifactorial, and it is generally accepted, that conventional risk factors determined only about 80% of cardiovascular risk. There is accumulating evidence that vitamin D exerts important pathophysiological effects on cardiovascular system. Low vitamin D was associated with increased cardiovascular risk in several reports. This review summarizes recent epidemiological evidence and possible pathophysiological mechanism for a role of low vitamin D in cardiovascular diseases. Moreover, available data concerning vitamin D supplementation are depicted.

    The endogenous competitive nitric oxide synthase inhibitor asymmetric dimethylarginine (ADMA) is an emerging risk marker for future cardiovascular events. Elevated ADMA concentrations have been described in patients with an adverse cardiovascular risk profile. Recently, various studies investigated the independent role of ADMA as a cardiovascular risk predictor in several patient cohorts. In addition, ADMA might not only be a risk marker but also a causative factor for cardiovascular disease. This review summarizes the literature on the relationship between ADMA, cardiovascular disease and diabetes.

    Ischemic stroke secondary to aortic dissection is not uncommon. We present a patient with left hemiplegia secondary to Stanford type A aortic dissection extending to the supra-aortic vessels, which was precipitated by rifle butt recoil chest injury. The diagnosis of aortic dissection was delayed due to various factors. Finally, the patient underwent successful Bentall procedure with complete resolution of symptoms. This case emphasizes the need for caution in the use of firearms for recreation and to take precautions in preventing such incidents. In addition, this case illustrates the need for prompt cardiovascular physical examination in patients presenting with stroke.

    The incidence of cancer (CA) has increased globally and radiotherapy (RT) is a vital component in its treatment. Cardiovascular injuries induced by RT in the treatment of thoracic and cervical CA have been causing problems in clinical practice for decades, and are among the most serious adverse effects of radiation experienced by the growing number of cancer survivors. This article presents a review on the Lilacs, Scielo and Pubmed databases of the main cardiovascular injuries, their mechanisms, clinical presentations, treatments and prevention proposals. Injuries caused by RT include diseases of the pericardium, coronary artery disease, valvular disease, myocardial disease with systolic and diastolic dysfunction, conduction disorders, and carotid artery and great vessels disease. Thoracic and cervical irradiation increases cardiovascular morbidity and mortality. Despite the great progress in the improvement of RT techniques, totally excluding prime areas of the cardiovascular system from the irradiation field is not yet possible. Guidelines must be created for monitoring, diagnosis and treatment of patients with CA treated with RT. (author)

  8. Nitric oxide synthase inhibition and oxidative stress in cardiovascular diseases: possible therapeutic targets?

    Nitric oxide (NO) is synthetized enzymatically from l-arginine (l-Arg) by three NO synthase isoforms, iNOS, eNOS and nNOS. The synthesis of NO is selectively inhibited by guanidino-substituted analogs of l-Arg or methylarginines such as asymmetric dimethylarginine (ADMA), which results from protein degradation in cells. Many disease states, including cardiovascular diseases and diabetes, are associated with increased plasma levels of ADMA. The N-terminal catalytic domain of these NOS isoforms binds the heme prosthetic group as well as the redox cofactor, tetrahydrobiopterin (BH(4)) associated with a regulatory protein, calmodulin (CaM). The enzymatic activity of NOS depends on substrate and cofactor availability. The importance of BH(4) as a critical regulator of eNOS function suggests that BH(4) may be a rational therapeutic target in vascular disease states. BH(4) oxidation appears to be a major contributor to vascular dysfunction associated with hypertension, ischemia/reperfusion injury, diabetes and other cardiovascular diseases as it leads to the increased formation of oxygen-derived radicals due to NOS uncoupling rather than NO. Accordingly, abnormalities in vascular NO production and transport result in endothelial dysfunction leading to various cardiovascular disorders. However, some disorders including a wide range of functions in the neuronal, immune and cardiovascular system were associated with the over-production of NO. Inhibition of the enzyme should be a useful approach to treat these pathologies. Therefore, it appears that both a lack and excess of NO production in diseases can have various important pathological implications. In this context, NOS modulators (exogenous and endogenous) and their therapeutic effects are discussed.

    Full Text Available Diabetes is a well-known risk factor of cardiovascular morbidity and mortality, and the beneficial effect of improved glycemic control on cardiovascular complications has been well established. However, the rosiglitazone experience aroused awareness of potential cardiovascular risk associated with diabetes drugs and prompted the U.S. Food and Drug Administration to issue new guidelines about cardiovascular risk. Through postmarketing cardiovascular safety trials, some drugs demonstrated cardiovascular benefits, while some antidiabetic drugs raised concern about a possible increased cardiovascular risk associated with drug use. With the development of new classes of drugs, treatment options became wider and the complexity of glycemic management in type 2 diabetes has increased. When choosing the appropriate treatment strategy for patients with type 2 diabetes at high cardiovascular risk, not only the glucose-lowering effects, but also overall benefits and risks for cardiovascular disease should be taken into consideration.

    2005-06-01

    In a recent DOE Program Review, Fermilab's director presented results of the laboratory's effort to reduce the injury rate over the last decade. The results, shown in the figure below, reveal a consistent and dramatic downward trend in OSHA recordable injuries at Fermilab. The High Energy Physics Program Office has asked Fermilab to report in detail on how the laboratory has achieved the reduction. In fact, the reduction in the injury rate reflects a change in safety culture at Fermilab, which has evolved slowly over this period, due to a series of events, both planned and unplanned. This paper attempts to describe those significant events and analyze how each of them has shaped the safety culture that, in turn, has reduced the rate of injury at Fermilab to its current value.

    Full Text Available Autism spectrum disorders (ASD are neurodevelopment disorders that cause severe and pervasive impairment in socialization, communication, and behavior. Although the availability of antipsychotic treatment in ASD has expanded, we will be very careful with side effects of these pharmacological agents. Following this reasoning, emerging data indicate that some antipsychotics may be associated with cardiovascular adverse events (e.g., QT interval prolongation, suggesting that this could be correlated to sudden death. Quite interesting, substantial evidence from epidemiological and case-control studies indicates that omega-3 reduces the risk of cardiovascular mortality, particularly sudden cardiac death. In accordance to the above mentioned findings, as omega-3 fatty acids per se have a direct cardiovascular protective role, our paper hypothesized that omega-3 fatty acids supplementation in ASD patients treated with atypical antipsychotic drugs may reduce cardiac arrhythmias and hence sudden cardiac death.As desordens do espectro autista (DEA são um grupo de doenças do desenvolvimento que causam um grave comprometimento na socialização, comunicação e comportamento.

    Pacher, Pál; Steffens, Sabine

    2009-06-01

    Endocannabinoids are endogenous bioactive lipid mediators present both in the brain and various peripheral tissues, which exert their biological effects via interaction with specific G-protein-coupled cannabinoid receptors, the CB(1) and CB(2). Pathological overactivation of the endocannabinoid system (ECS) in various forms of shock and heart failure may contribute to the underlying pathology and cardiodepressive state by the activation of the cardiovascular CB(1) receptors. Furthermore, tonic activation of CB(1) receptors by endocannabinoids has also been implicated in the development of various cardiovascular risk factors in obesity/metabolic syndrome and diabetes, such as plasma lipid alterations, abdominal obesity, hepatic steatosis, inflammation, and insulin and leptin resistance. In contrast, activation of CB(2) receptors in immune cells exerts various immunomodulatory effects, and the CB(2) receptors in endothelial and inflammatory cells appear to limit the endothelial inflammatory response, chemotaxis, and inflammatory cell adhesion and activation in atherosclerosis and reperfusion injury. Here, we will overview the cardiovascular actions of endocannabinoids and the growing body of evidence implicating the dysregulation of the ECS in a variety of cardiovascular diseases. We will also discuss the therapeutic potential of the modulation of the ECS by selective agonists/antagonists in various cardiovascular disorders associated with inflammation and tissue injury, ranging from myocardial infarction and heart failure to atherosclerosis and cardiometabolic disorders.

    Objective To analyze the temporal trend of premature mortalities burden due to major cardiovascular diseases (CVD) including hypertension, stroke, and ischemic heart disease (IHD) for the years 2006-2010 in TongHai country of Yunnan province. Methods Using the death monitoring statistics of Tonghai county in 2006-2010, years of life lost (YLL) was used to measure premature mortality burden due to major cardiovascular diseases. YLL per 1 000 population rate was calculated by year, sex and age group without age-weighting but with 3% discounting rate. Results From 2006 to 2010, IHD was among the top ten leading causes of premature deaths, whereas stroke had been the top leading cause of premature deaths since 2007. The standardized YLL rate of stroke and IHD increased with year across these five years, whereas the YLL rate of hypertension fluctuated over time. The highest rates occurred among persons aged greater than 60 years, and YLL rates of three major CVDs fluctuated over time among different age groups. Predominance of stroke in overall YLL rates in both sexes was noticed throughout the whole observed period. Females had higher YLL rates of hypertension disease and IHD than males. Conclusion The premature mortality burden due to stroke and IHD increased with year across these five years. And measures to reduce mortality of stroke and IHD are urgently needed.%目的 分析云南省通海县2006-2010年主要心脑血管疾病(高血压性疾病、脑卒中、缺血性心脏病)早死所致疾病负担的时间趋势.方法 采用2006-2010年通海县的全死因监测资料,以早死所致生命损失年(years of life lost,YLL)作为3种主要疾病负担的测量单位,采用3%的贴现率但不采用年龄权重分年份、性别和年龄组计算标化每千人口YLL率.结果 2006-2010连续5年,缺血性心脏病的死因顺位排在该地区的前10位.自2007年,脑卒中的死因顺位排在该地区的第1位.脑卒中和缺血性心脏病的标化YLL

    While overt vitamin B6 deficiency is not a frequent finding nowadays in medical practice, evidence suggests that insufficiency of this vitamin is rather widespread in a quite large portion of the population such as the elderly or in not unusual conditions such as that of alcohol addiction. Moreover, a mild deficiency in B6 vitamin is a state that may be associated with an increased risk of cardiovascular disease. Epidemiologic evidence from case control and prospective studies have suggested that low dietary intake or reduced blood concentrations of vitamin B6 is associated with an increased risk of cardiovascular disease, although most recent trials demonstrated the ineffectiveness of vitamin B6 supplementation on the prevention of cardiovascular events recurrence. Due to limited and somewhat inconsistent data together with the ample variety of critical functions in which vitamin B6 is involved in the human body, it is very challenging to attempt at establishing a cause and effect relationship between vitamin B6 and risk of cardiovascular disease as it is to delineate the exact mechanism(s) by which vitamin B6 may modulate such risk. In the present chapter we review the currently available knowledge deriving from both epidemiological and mechanistic studies designed to define potential candidate mechanisms for the association of vitamin B6 impairment and risk of cardiovascular disease development.

    Myeloperoxidase (MPO) is a leukocyte-derived enzyme that catalyzes the formation of a number of reactive oxidant species. In addition to being an integral component of the innate immune response, evidence has emerged that MPO-derived oxidants contribute to tissue damage during inflammation. MPO-catalyzed reactions have been attributed to potentially proatherogenic biological activities throughout the evolution of cardiovascular disease, including during initiation, propagation, and acute complication phases of the atherosclerotic process. As a result, MPO and its downstream inflammatory pathways represent attractive targets for both prognostication and therapeutic intervention in the prophylaxis of atherosclerotic cardiovascular disease.

    Full Text Available Abstract Background Animal and organ culture experiments have shown beneficial inhibitory estrogen effects on post injury neointima development. The purpose of this study was to investigate whether such estrogen effects are influenced by the estrogen receptor antagonist ICI 182,780. Different concentrations of 17β-estradiol and the phytoestrogens genistein and daidzein were tested. Methods F emale New Zealand White rabbits were benumbed. In situ vascular injury of the thoracic and abdominal aorta was performed by a 3F Fogarty catheter. Segments of 5 mm were randomised and held in culture for 21 days. Three test series were performed: 1 control group – 20 μM ICI – 30 μM ICI – 40 μM ICI. 2 control group – 20 μM ICI – 40 μM 17β-estradiol – 40 μM 17β-estradiol + 20 μM ICI. 3 control group – 20 μM ICI – 40 μM daidzein – 40 μM daidzein + 20 μM ICI – 20 μM genistein – 20 μM genistein + 20 μM ICI. After 21 days the neointima-media-ratio was evaluated. Results 1 Treatment with ICI 182,780 did not reduce neointima formation significantly (p = 0.05. 2 40 μM 17β-estradiol alone (p Conclusions The estrogen receptor antagonist ICI 182,780 did not modulate the inhibitory estrogen effects on post injury neointima formation.

    2015-01-01

    Full Text Available Myocardial ischemia-reperfusion (I/R injury is experienced by individuals suffering from cardiovascular diseases such as coronary heart diseases and subsequently undergoing reperfusion treatments in order to manage the conditions. The occlusion of blood flow to the tissue, termed ischemia, can be especially detrimental to the heart due to its high energy demand. Several cellular alterations have been observed upon the onset of ischemia. The danger created by cardiac ischemia is somewhat paradoxical in that a return of blood to the tissue can result in further damage. Reactive oxygen species (ROS have been studied intensively to reveal their role in myocardial I/R injury. Under normal conditions, ROS function as a mediator in many cell signaling pathways. However, stressful environments significantly induce the generation of ROS which causes the level to exceed body’s antioxidant defense system. Such altered redox homeostasis is implicated in myocardial I/R injury. Despite the detrimental effects from ROS, low levels of ROS have been shown to exert a protective effect in the ischemic preconditioning. In this review, we will summarize the detrimental role of ROS in myocardial I/R injury, the protective mechanism induced by ROS, and potential treatments for ROS-related myocardial injury.

    Previous studies have shown that Japanese taxi drivers are exposed to more risk factors and have a higher mortality rate due to cardiovascular disease than other occupational groups. We investigated the effect of night taxi driving with a view to preventing acute events of cardiovascular disease among aged taxi drivers. Twenty-nine taxi drivers (41-67 years old) were examined for urine normetanephrine/creatinine, von Willebrand factor, anti-thrombin III, t-plasminogen activator-plasminogen activator inhibitor 1-complex, hematocrit, blood glucose and blood pressure in the morning and at midnight during a duty day and in the following morning. At the same time, the blood pressure and blood glucose of 46 taxi drivers (43-67 years old) in the morning after a night duty with little sleep and in the morning after daytime work and subsequent night sleep were compared. The results obtained indicate that the aggravation of sympathetic nervous system functions with disturbed circadian rhythms, increased blood coagulation and blood concentration, endothelial injury and the elevation of blood glucose at midnight or the next morning were induced by their night work. These conditions are supposed to favour acute vascular events in aged taxi drivers. Preventive measures considered include social support for anticoagulant food and water intake, short exercise and walking as well as taking a rest and a nap during night work.

    Cardiovascular Diseases (CD) are currently one of the most common causes of death. Because heart related deaths occur on such an enormous scale this phenomenon is referred to as an epidemic. Chronic and acute injury of the heart could be an effect of cardiac remodeling, which is a result of molecular, cellular and interstitial changes, influenced by hemodynamic load or neurohormonal activation (Cohn et al., 2000). These small deviations in cardiac activity and morphology may lead to an enormous negative effect. Despite a significant progress, knowledge of standard risk factors for cardiovascular diseases has become less and less effective, which is why predicting and seeking an appropriate treatment is very challenging. As a result, there is a growing interest in finding new markers of the CD. MicroRNAs (miRNAs), are short, non-coding RNAs responsible for regulation of gene expression at the post-transcriptional level. Among them that have the greatest potential are microRNA molecules that circulate in the blood plasma or serum, that are related to direct activation of signaling pathways, implicated in the aging process and thus for the development of cardiovascular disease. This paper is a summary of the current state of knowledge on miRNAs, their biogenesis and potential role as biomarkers to diagnose heart disease.

    Marijuana is currently the most used illicit substance in the world. With the current trend of decriminalization and legalization of marijuana in the US, physicians in the US will encounter more patients using marijuana recreationally over a diverse range of ages and health states. Therefore, it is relevant to review marijuana's effects on human cardiovascular physiology and disease. Compared with placebo, marijuana cigarettes cause increases in heart rate, supine systolic and diastolic blood pressures, and forearm blood flow via increased sympathetic nervous system activity. These actions increase myocardial oxygen demand to a degree that they can decrease the time to exercise-induced angina in patients with a history of stable angina. In addition, marijuana has been associated with triggering myocardial infarctions (MIs) in young male patients. Smoking marijuana has been shown to increase the risk of MI onset by a factor of 4.8 for the 60 minutes after marijuana consumption, and to increase the annual risk of MI in the daily cannabis user from 1.5% to 3% per year. Human and animal models suggest that this effect may be due to coronary arterial vasospasm. However, longitudinal studies have indicated that marijuana use may not have a significant effect on long-term mortality. While further research is required to definitively determine the impact of marijuana on cardiovascular disease, it is reasonable to recommend against recreational marijuana use, especially in individuals with a history of coronary artery disorders.

  10. Dietary fat and cardiovascular disease?

    Full Text Available Dietary saturated fat (SF intake has been shown to increase low density lipoprotein (LDL cholesterol and therefore has been associated with increased risk of cardiovascular disease (CVD. This evidence coupled with inferences from epidemiologic studies and clinical trials, had led to longstanding public health recommendations for limiting SF intake as a means of preventing CVD. However the relationship between SF and CVD risk remains controversial, due at least in part to the intrinsic limitations of clinical studies that have evaluated this relationship. A recent meta analysis showed that current evidence does not clearly support cardiovascular guidelines that encourage high consumption of polyunsaturated fatty acids (PUFA and low consumption of total SF. They found weak positive associations between circulating palmitic and stearic acids (found largely in palm oil and animal fats, respectively and CVD, whereas circulating margaric acid (a dairy fat significantly reduced the risk of CVD.(2,3 Saturated fat are not associated with all cause mortality, CVD, CHD, ischemic stroke or type 2 diabetes, but the evidence is heterogenous with methodological limitations.

    Extensor tendon injuries are very common injuries, which inappropriately treated can cause severe lasting impairment for the patient. Assessment and management of flexor tendon injuries has been widely reviewed, unlike extensor injuries. It is clear from the literature that extensor tendon repair should be undertaken immediately but the exact approach depends on the extensor zone. Zone I injuries otherwise known as mallet injuries are often closed and treated with immobilisaton and conservative management where possible. Zone II injuries are again conservatively managed with splinting. Closed Zone III or ‘boutonniere’ injuries are managed conservatively unless there is evidence of displaced avulsion fractures at the base of the middle phalanx, axial and lateral instability of the PIPJ associated with loss of active or passive extension of the joint or failed non-operative treatment. Open zone III injuries are often treated surgically unless splinting enable the tendons to come together. Zone V injuries, are human bites until proven otherwise requires primary tendon repair after irrigation. Zone VI injuries are close to the thin paratendon and thin subcutaneous tissue which strong core type sutures and then splinting should be placed in extension for 4-6 weeks. Complete lacerations to zone IV and VII involve surgical primary repair followed by 6 weeks of splinting in extension. Zone VIII require multiple figure of eight sutures to repair the muscle bellies and static immobilisation of the wrist in 45 degrees of extension. To date there is little literature documenting the quality of repairing extensor tendon injuries however loss of flexion due to extensor tendon shortening, loss of flexion and extension resulting from adhesions and weakened grip can occur after surgery. This review aims to provide a systematic examination method for assessing extensor injuries, presentation and management of all type of extensor tendon injuries as well as guidance on

  13. Pharmacogenetics of cardiovascular drugs.

    Johnson, Julie A; Humma, Larisa M

    2002-02-01

    Pharmacogenetics is a field aimed at understanding the genetic contribution to inter-patient variability in drug efficacy and toxicity. Treatment of cardiovascular disease is, in most cases, guided by evidence from well-controlled clinical trials. Given the solid scientific basis for the treatment of most cardiovascular diseases, it is common for patients with a given disease to be treated in essentially the same manner. Thus, the clinical trials have been very informative about treating large groups of patients with a given disease, but are slightly less informative about the treatment of individual patients. Pharmacogenetics and pharmacogenomics have the potential of taking the information derived from large clinical trials and further refining it to select the drugs with the greatest likelihood for benefit, and least likelihood for harm, in individual patients, based on their genetic make-up. In this paper, the current literature on cardiovascular pharmacogenetics is emphasised, and how the use of pharmacogenetic/pharmacogenomic information may be particularly useful in the future in the treatment of cardiovascular diseases is also highlighted.

  15. Cardiovascular effects of gliptins.

    Scheen, André J

    2013-02-01

    Dipeptidyl peptidase 4 (DPP-4) inhibitors (commonly referred to as gliptins) are a novel class of oral antihyperglycaemic agents with demonstrated efficacy in the treatment of type 2 diabetes mellitus (T2DM). Preclinical data and mechanistic studies have indicated a possible beneficial action on blood vessels and the heart, via both glucagon-like peptide 1 (GLP-1)-dependent and GLP-1-independent effects. DPP-4 inhibition increases the concentration of many peptides with potential vasoactive and cardioprotective effects. Clinically, DPP-4 inhibitors improve several risk factors in patients with T2DM. They improve blood glucose control (mainly by reducing postprandial glycaemia), are weight neutral (or even induce modest weight loss), lower blood pressure, improve postprandial lipaemia, reduce inflammatory markers, diminish oxidative stress, and improve endothelial function. Some positive effects on the heart have also been described in patients with ischaemic heart disease or congestive heart failure, although their clinical relevance requires further investigation. Post-hoc analyses of phase II-III, controlled trials suggest a possible cardioprotective effect with a trend for a lower incidence of major cardiovascular events with gliptins than with placebo or active agents. However, the actual relationship between DPP-4 inhibition and cardiovascular outcomes remains to be proven. Major prospective clinical trials with predefined cardiovascular outcomes and involving various DPP-4 inhibitors are now underway in patients with T2DM and a high-risk cardiovascular profile.

    1991-06-01

    Regulations controlling the sport of paragliding were issued in April 1987 by the German Department of Transportation. The growing popularity of this sport has led to a steady increase in the number of associated injuries. This study presents the incidence, localization and degree of injuries associated with paragliding documented in Germany, Austria and Switzerland. The 283 injuries suffered by 218 paragliders were documented in the period 1987-1989: 181 occurred during landing, 28 during starting procedures and nine during flight. The mean patient age was 29.6 years. There were 34.9% spinal injuries, 13.4% upper extremity injuries and 41.3% lower limb injuries. Over half of these injuries were treated surgically and in 54 instances permanent disability remained. In paragliding the lower extremities are at greatest risk of injury during landing. Proper equipment, especially sturdy footwear, exact training in landing techniques as well as improved instruction in procedures during aborted or crash landings is required to reduce the frequency of these injuries.

    The plasma pool of potassium is a partial reflection of the overall body, transient cellular shifts, and potassium elimination regulated by the kidneys. Potassium concentrations elevating above the upper limit of normal (> 5.0 mEq/L) have become more common in cardiovascular practice due to the growing population of patients with chronic kidney disease and the broad applications of drugs that modulate potassium excretion by either reducing production of angiotensin II (angiotensin-converting enzyme inhibitors, direct renin inhibitors, beta-adrenergic receptor antagonists), blocking angiotensin II receptors (angiotensin receptor blockers), or antagonizing the action of aldosterone on mineralocorticoid receptors (mineralocorticoid receptor antagonists). In addition, acute kidney injury, critical illness, crush injuries, and massive red blood cell transfusions can result in hyperkalemia. Progressively more severe elevations in potassium are responsible for abnormalities in cardiac depolarization and repolarization and contractility. Untreated severe hyperkalemia results in sudden cardiac death. Traditional management steps have included reducing dietary potassium and discontinuing potassium supplements; withdrawal of exacerbating drugs; acute treatment with intravenous calcium gluconate, insulin, and glucose; nebulized albuterol; correction of acidosis with sodium bicarbonate for short-term shifts out of the plasma pool; and, finally, gastrointestinal ion exchange with oral sodium polystyrene sulfonate in sorbitol, which is mainly used in the hospital and is poorly tolerated due to gastrointestinal adverse effects. This review explores hyperkalemia as a complication in cardiovascular patients and highlights new acute, chronic, and preventative oral therapies (patiromer calcium, cross-linked polyelectrolyte, ZS-9) that could potentially create a greater margin of safety for vulnerable patients with combined heart and kidney disease.

    Full Text Available Introduction. The aim of study was to analyze risk factors, mechanisms of injury, symptoms and time that elapsed from injury until operation of complete quadriceps tendon ruptures. Material and Methods. This retrospective multicenter study included 30 patients operated for this injury, of whom 28 (93.3% were men. The average age was 53.7 years (18-73. Twenty-six patients had reconstruction of unilateral rupture and four of bilateral one. Results. Eighty percent of them had some risk factors for rupture of the tendon with degenerative changes. Eight patients had diabetes, seven patients were on renal dialysis, two patients had secondary hyperparathyroidism, five patients were obese and two patients had former knee operations. These injuries occurred in 80% following minor trauma caused by falls on stairs, on flat surfaces and squatting. The most frequent symptoms were: pain, swelling, lack of extension of knee and defect above patella, and three cases were initially misdiagnosed. During the first 10 days after injury, acute and chronic ruptures were reconstructed in 22 (73.3% and 8 patients, respectively. Conclusion. Quadriceps tendon injuries most often happen to male patients with predisposing conditions in their fifth and sixth decade of life due to trivial trauma. Patients on renal dialysis are the most vulnerable population group.

Materials and Methods: This retrospective, multicenter case series of ocular injury due to cluster bombs was conducted for 3 years after the war in South Lebanon (July 2006. Data were gathered from the reports to the Information Management System for Mine Action. Results: There were 308 victims of clusters bombs; 36 individuals were killed, of which 2 received ocular lacerations and; 272 individuals were injured with 18 receiving ocular injury. These 18 surviving individuals were assessed by the authors. Ocular injury occurred in 6.5% (20/308 of cluster bomb victims. Trauma to multiple organs occurred in 12 of 18 cases (67% with ocular injury. Ocular findings included corneal or scleral lacerations (16 eyes, corneal foreign bodies (9 eyes, corneal decompensation (2 eyes, ruptured cataract (6 eyes, and intravitreal foreign bodies (10 eyes. The corneas of one patient had extreme attenuation of the endothelium. Conclusions: Ocular injury occurred in 6.5% of cluster bomb victims and 67% of the patients with ocular injury sustained trauma to multiple organs. Visual morbidity in civilians is an additional reason for a global ban on the use of cluster bombs.

    2015-01-01

    Full Text Available Each year, some 30 percent of global deaths are caused by cardiovascular diseases. This figure is worsening due to both the increasing elderly population and severe shortages of medical personnel. The development of a cardiovascular diseases classifier (CDC for auto-diagnosis will help address solve the problem. Former CDCs did not achieve quick evaluation of cardiovascular diseases. In this letter, a new CDC to achieve speedy detection is investigated. This investigation incorporates the analytic hierarchy process (AHP-based multiple criteria decision analysis (MCDA to develop feature vectors using a Support Vector Machine. The MCDA facilitates the efficient assignment of appropriate weightings to potential patients, thus scaling down the number of features. Since the new CDC will only adopt the most meaningful features for discrimination between healthy persons versus cardiovascular disease patients, a speedy detection of cardiovascular diseases has been successfully implemented.

    2011-01-01

    We need to find novel ways of increasing exercise participation, particularly in those populations who find it difficult to participate in voluntary exercise. In recent years researchers have started to investigate the potential for using electrical stimulation to artificially stimulate a pattern of muscle activity that would induce a physiological response consistent with cardiovascular exercise. Work to date has indicated that this is best achieved by using a stimulation protocol that results in rapid rhythmical isometric contractions of the large leg muscle groups at sub tetanic frequencies. Studies completed by our group indicate that this technique can serve as a viable alternative to voluntary cardiovascular exercise. Apart from being able to induce a cardiovascular exercise effect in patient populations (e.g. heart failure, COPD, spinal cord injury, obesity), this approach may also have value in promotion of exercise activity in a microgravity environment.

    Full Text Available Migraine, especially migraine with aura is an established risk factor for ischemic lesions of the brain. Recent evidence has also linked migraine with and without aura to a broader range of ischemic vascular disorders including angina, myocardial infarction, coronary revascularization, claudication and cardiovascular mortality. The topic is therefore of considerable interest. Accordingly, herein we review the association between migraine and cardiovascular disease. We start by briefly presenting diagnostic criteria for migraine and revising its pathophysiology. We follow by summarizing the evidence on the topic. We then briefly present the results of a recent meta-analysis. We close by highlighting results of a large epidemiological study conducted after the publication of the meta-analysis.

    2008-05-01

    Full Text Available Prodrugs are biologically inactive derivatives of an active drug intended to solve certain problems of the parent drug such as toxicity, instability, minimal solubility and non-targeting capabilities. The majority of drugs for cardiovascular diseases undergo firstpass metabolism, resulting in drug inactivation and generation of toxic metabolites, which makes them appealing targets for prodrug design. Since prodrugs undergo a chemical reaction to form the parent drug once inside the body, this makes them very effective in controlling the release of a variety of compounds to the targeted site. This review will provide the reader with an insight on the latest developments of prodrugs that are available for treating a variety of cardiovascular diseases. In addition, we will focus on several drug delivery methodologies that have merged with the prodrug approach to provide enhanced target specificity and controlled drug release with minimal side effects.

    Sulfur dioxide (SO2) was previously regarded as a toxic gas in atmospheric pollutants. But it has been found to be endogenously generated from metabolism of sulfur-containing amino acids in mammals through transamination by aspartate aminotransferase (AAT). SO2 could be produced in cardiovascular tissues catalyzed by its synthase AAT. In recent years, studies revealed that SO2 had physiological effects on the cardiovascular system, including vasorelaxation and cardiac function regulation. In addition, the pathophysiological effects of SO2 were also determined. For example, SO2 ameliorated systemic hypertension and pulmonary hypertension, prevented the development of atherosclerosis, and protected against myocardial ischemia-reperfusion (I/R) injury and isoproterenol-induced myocardial injury. These findings suggested that endogenous SO2 was a novel gasotransmitter in the cardiovascular system and provided a new therapy target for cardiovascular diseases. PMID:26839635

    Becak DP, Holland NA; Shannahan, Jonathan H.

    2015-10-01

    Background: Silver nanoparticles (AgNP) have garnered much interest due to their antimicrobial properties, becoming one of the most utilized nano scale materials. However, any potential evocable cardiovascular injury associated with exposure has not been previously reported. We have previously demonstrated expansion of myocardial infarction after intratracheal (IT) instillation of other nanomaterials. We hypothesized that pulmonary exposure to Ag core AgNP induces persistent increase in circulating cytokines, expansion of cardiac ischemia-reperfusion (I/R) injury and associated with altered coronary vessel reactivity. Methods: Male Sprague-Dawley rats were exposed to 200 µg of 20 nm citrate capped Ag core AgNP, or a citrate vehicle intratracheally (IT). One and 7 days following IT instillation lungs were evaluated for inflammation and silver presence, serum was analyzed for concentrations of selected cytokines, and cardiac I/R injury and coronary artery reactivity was assessed. Results: AgNP instillation resulted in modest pulmonary injury with detection of silver in lung tissue and infiltrating cells, elevation of serum cytokines: G-CSF, MIP-1α, IL-1β, IL-2, IL-6, IL-13, IL-10, IL-18, IL-17, TNFα, and RANTES, expansion of I/R injury and depression of the coronary vessel reactivity at 1 day post IT compared to vehicle treated rats. Seven days post IT instillation was associated with persistent detection of silver in lungs, elevation in cytokines: IL-2, IL-13, and TNFα and expansion of I/R injury. Conclusions: Based on these data, IT instillation of AgNP increases circulating levels of several cytokines, which may contribute to persistent expansion of I/R injury possibly through an impaired vascular responsiveness.

    2016-03-01

    Cardiovascular diseases are the leading cause of death affecting 17.3 million people across the globe and are estimated to affect 23.3 million people by year 2030. In recent years, about 7.3 million people died due to coronary heart disease, 9.4 million deaths due to high blood pressure and 6.2 million due to stroke, where obesity and atherosclerotic progression remain the chief pathological factors. The search for newer and better cardiovascular agents is the foremost need to manage cardiac patient population across the world. Several natural and (semi) synthetic chalcones deserve the credit of being potential candidates to inhibit various cardiovascular, hematological and anti-obesity targets like angiotensin converting enzyme (ACE), cholesteryl ester transfer protein (CETP), diacylglycerol acyltransferase (DGAT), acyl-coenzyme A: cholesterol acyltransferase (ACAT), pancreatic lipase (PL), lipoprotein lipase (LPL), calcium (Ca(2+))/potassium (K(+)) channel, COX-1, TXA2 and TXB2. In this review, a comprehensive study of chalcones, their therapeutic targets, structure activity relationships (SARs), mechanisms of actions (MOAs) have been discussed. Chemically diverse chalcone scaffolds, their derivatives including structural manipulation of both aryl rings, replacement with heteroaryl scaffold(s) and hybridization through conjugation with other pharmacologically active scaffold have been highlighted. Chalcones which showed promising activity and have a well-defined MOAs, SARs must be considered as prototype for the design and development of potential anti-hypertensive, anti-anginal, anti-arrhythmic and cardioprotective agents. With the knowledge of these molecular targets, structural insights and SARs, this review may be helpful for (medicinal) chemists to design more potent, safe, selective and cost effective chalcone derivatives as potential cardiovascular agents.

    Diabetes mellitus currently affects more than 170 million individuals worldwide and is expected to afflict another 200 million individuals in the next 30 years. Complications of diabetes as a result of oxidant stress affect multiple systems throughout the body, but involvement of the cardiovascular system may be one of the most severe in light of the impact upon cardiac and vascular function that can result in rapid morbidity and mortality for individuals. Given these concerns, the signaling pathways of the mammalian target of rapamycin (mTOR) offer exciting prospects for the development of novel therapies for the cardiovascular complications of diabetes. In the cardiovascular and metabolic systems, mTOR and its multi-protein complexes of TORC1 and TORC2 regulate insulin release and signaling, endothelial cell survival and growth, cardiomyocyte proliferation, resistance to β-cell injury, and cell longevity. Yet, mTOR can, at times, alter insulin signaling and lead to insulin resistance in the cardiovascular system during diabetes mellitus. It is therefore vital to understand the complex relationship mTOR and its downstream pathways hold during metabolic disease in order to develop novel strategies for the complications of diabetes mellitus in the cardiovascular system.

    Inevitably, a small proportion of patients with systematic hypertension will develop hypertensive crisis at some point. Hypertensive crises can be divided into hypertensive emergency or hypertensive urgency according to the presence or lack of acute target organ damage. In this review, we discuss cardiovascular hypertensive emergencies, including acute coronary syndrome, aortic dissection, congestive heart failure, and sympathomimetic hypertensive crises, including those caused by cocaine use. Each presents in a unique fashion, although some hypertensive emergency patients report nonspecific symptoms. Treatment includes several effective and rapid-acting medications to safely reduce the blood pressure, protect remaining end-organ function, relieve symptoms, minimize the risk of complications, and thereby improve patient outcomes.

    The cardiovascular system of the fetus is physiologically different than the adult, mature system. Unique characteristics of the myocardium and specific channels of blood flow differentitate the physiology of the fetus from the newborn. Conditions of increased preload and afterload in the fetus, such as sacrococcygeal teratoma and twin-twin transfusion syndrome, result in unique and complex pathophysiological states. Echocardiography has improved our understanding of human fetal cadiovasvular physiology in the normal and diseased states, and has expanded our capability to more effectively treat these disease processes.

    Cardiovascular disease (CVD) is the leading cause of the death worldwide. An increasing number of studies have found that autophagy is involved in the progression or prevention of CVD. However, the precise mechanism of autophagy in CVD, especially the myocardial ischaemia-reperfusion injury (MI/R injury), is unclear and controversial. Here, we show that the cardiomyocyte-specific disruption of autophagy by conditional knockout of Atg7 leads to severe contractile dysfunction, myofibrillar disarray and vacuolar cardiomyocytes. A negative cytoskeleton organization regulator, CLP36, was found to be accumulated in Atg7-deficient cardiomyocytes. The cardiomyocyte-specific knockout of Atg7 aggravates the MI/R injury with cardiac hypertrophy, contractile dysfunction, myofibrillar disarray and severe cardiac fibrosis, most probably due to CLP36 accumulation in cardiomyocytes. Altogether, this work reveals autophagy may protect cardiomyocytes from the MI/R injury through the clearance of CLP36, and these findings define a novel relationship between autophagy and the regulation of stress fibre in heart.

    Sports related injuries are common in children and adolescents, with a reported incidence of around one in ten children each year. Boys incur more and severer sports injuries than girls, and chance for injury is greater with contact or jumping sports. Sports injuries seen in children under 10-years of age are non-specific, including contusions, mild sprains, and extremity fractures, usually Salter fractures of the physes (growth plate) or plastic fractures. In the very young athlete, sports injury of the ligaments or muscle is rare as are spine or head injuries. With growth and adolescence, the intensity of sports involvement increases. Pre-pubertal children still have open physes that are prone to injury, both acute or due to stress from a repetitive activity. In addition to injury of the physes of the long bones, injuries to the physes of apophyses are common. Ligamentous injury is uncommon before physeal closure, but can occur. After the physes fuse, ligamentous injury is seen with patterns similar to adults. This review will include a description of sports related injuries seen in children and adolescents. We will concentrate on injuries that are specific for the growing skeleton, with a brief mention of those seen after fusion of the physes.

The American Heart Association, the Centers for Disease Control and Prevention and the American College of Sports Medicine all recommend regular physical activity of moderate intensity for the prevention and complementary treatment of several diseases. The therapeutic role of exercise in maintaining good health and treating diseases is not new. The benefits of physical activity date back to Susruta, a 600 BC physician in India, who prescribed exercise to patients. Hippocrates (460–377 BC wrote “in order to remain healthy, the entire day should be devoted exclusively to ways and means of increasing one's strength and staying healthy, and the best way to do so is through physical exercise.” Plato (427–347 BC referred to medicine as a sister art to physical exercise while the noted ancient Greek physician Galen (129–217 AD penned several essays on aerobic fitness and strengthening muscles.

    Full Text Available The increased incidence of cardiovascular diseases (CVDs has stimulated research for substances that could improve cardiovascular health. Among them, resveratrol (RES, a polyphenolic compound notably present in grapes and red wine, has been involved in the “French paradox”. RES is known for its antioxidant and anti-inflammatory properties and for its ability to upregulate endothelial NO synthase (eNOS. RES was able to scavenge •OH/O2•− and peroxyl radicals, which can limit the lipid peroxidation processes. Moreover, in bovine aortic endothelial cells (BAEC under glucose-induced oxidative stress, RES restored the activity of dimethylargininedimethylaminohydrolase (DDAH, an enzyme that degrades an endogenous inhibitor of eNOS named asymmetric dimethylarginine (ADMA. Thus, RES could improve •NO availability and decrease the endothelial dysfunction observed in diabetes. Preclinical studies have made it possible to identify molecular targets (SIRT-1, AMPK, Nrf2, NFκB…; however, there are limited human clinical trials, and difficulties in the interpretation of results arise from the use of high-dose RES supplements in research studies, whereas low RES concentrations are present in red wine. The discussions on potential beneficial effects of RES in CVDs (atherosclerosis, hypertension, stroke, myocardial infarction, heart failure should compare the results of preclinical studies with those of clinical trials.

    The dramatic change of the natural history of HIV-infected patients by highly active antiretroviral therapy (HAART) has exposed these patients to cardiovascular risk, including cardiovascular disease and hypertension. In HIV-infected patients, the development of arterial hypertension, at least in the medium-long term is an established feature, although recognized predictors of its development have not been clearly identified. In addition, conflicting data regarding the influence of antiretroviral therapy (ART) are reported. The presence of a proinflammatory state and oxidative stress-mediated endothelial dysfunction seem, however, to play a pathophysiologic role. In this review, we examine and provide a comprehensive, literature based, consideration of the pathophysiologic aspects of hypertension in these patients. HIV-infected patients, independently of the presence of hypertension, remain at very high cardiovascular risk due to the presence of the same cardiovascular risk factors recognized for the general population with, in addition, the indirect influence of the ART, essentially via its effect on lipid metabolism. This review based on the evidence from the literature, concludes that the management of HIV-infected patients in terms of cardiovascular prevention emerges as a priority. The consideration of cardiovascular risk in these patients should receive the same emphasis given for the general population at high cardiovascular risk, including adequate blood pressure control according to international guidelines.

    In this paper, a first in a Series of two, we look at the evidence for an association of post-traumatic stress disorder with incident cardiovascular disease risk and the mechanisms that might cause this association, as well as the prevalence of post-traumatic stress disorder due to cardiovascular disease events and its associated prognostic risk. We discuss research done after the publication of previous relevant systematic reviews, and survey currently funded research from the two most active funders in the field: the National Institutes of Health and the US Veterans Administration. We conclude that post-traumatic stress disorder is a risk factor for incident cardiovascular disease, and a common psychiatric consequence of cardiovascular disease events that might worsen the prognosis of the cardiovascular disease. There are many candidate mechanisms for the link between post-traumatic stress disorder and cardiovascular disease, and several ongoing studies could soon point to the most important behavioural and physiological mechanisms to target in early phase intervention development. Similarly, targets are emerging for individual and environmental interventions that might offset the risk of post-traumatic stress disorder after cardiovascular disease events.

  6. Cyclophilin A in cardiovascular homeostasis and diseases.

    Vascular homeostasis is regulated by complex interactions between many vascular cell components, including endothelial cells, vascular smooth muscle cells (VSMCs), adventitial inflammatory cells, and autonomic nervous system. The balance between oxidant and antioxidant systems determines intracellular redox status, and their imbalance can cause oxidative stress. Excessive oxidative stress is one of the important stimuli that induce cellular damage and dysregulation of vascular cell components, leading to vascular diseases through multiple pathways. Cyclophilin A (CyPA) is one of the causative proteins that mediate oxidative stress-induced cardiovascular dysfunction. CyPA was initially discovered as the intracellular receptor of the immunosuppressive drug cyclosporine 30 years ago. However, recent studies have established that CyPA is secreted from vascular cell components, such as endothelial cells and VSMCs. Extracellular CyPA augments the development of cardiovascular diseases. CyPA secretion is regulated by Rho-kinase, which contributes to the pathogenesis of vasospasm, arteriosclerosis, ischemia/reperfusion injury, hypertension, pulmonary hypertension, and heart failure. We recently reported that plasma CyPA levels are significantly higher in patients with coronary artery disease, which is associated with increased numbers of stenotic coronary arteries and the need for coronary intervention in such patients. Furthermore, we showed that the vascular erythropoietin (Epo)/Epo receptor system plays an important role in production of nitric oxide and maintenance of vascular redox state and homeostasis, with a potential mechanistic link to the Rho-kinase-CyPA pathway. In this article, I review the data on the protective role of the vascular Epo/Epo receptor system and discuss the roles of the CyPA/Rho-kinase system in cardiovascular diseases.

    Use of complex cardiovascular system models, in conjunction with a large hybrid computer, in biomedical engineering courses. A cardiovascular blood pressure-flow model, driving a compartment model for the study of dye transport, was set up on the computer for use as a laboratory exercise by students who did not have the computer experience or skill to be able to easily set up such a simulation involving some 27 differential equations running at 'real time' rate. The students were given detailed instructions regarding the model, and were then able to study effects such as those due to septal and valve defects upon the pressure, flow, and dye dilution curves. The success of this experiment in the use of involved models in engineering courses was such that it seems that this type of laboratory exercise might be considered for use in physiology courses as an adjunct to animal experiments.

    Full Text Available Patients with rheumatic diseases have an increased risk of mortality by cardiovascular events. In fact, several rheumatic diseases such as rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, and ankylosing spondylitis are associated with a higher prevalence of cardiovascular diseases (CVDs. Although traditional cardiovascular risk factors have been involved in the pathogenesis of cardiovascular diseases in rheumatic patients, these alterations do not completely explain the enhanced cardiovascular risk in this population. Obesity and its pathologic alteration of fat mass and dysfunction, due to an altered pattern of secretion of proinflammatory adipokines, could be one of the links between cardiovascular and rheumatic diseases. Indeed, the incidence of CVDs is augmented in obese individuals with rheumatic disorders. Thus, in this paper we explore in detail the relationships among adipokines, rheumatic diseases, and cardiovascular complications by giving to the reader a holistic vision and several suggestions for future perspectives and potential clinical implications.

    Patients with chronic kidney disease (CKD) have a high prevalence of atherosclerotic cardiovascular disease, likely reflecting the presence of traditional risk factors. A greater distinguishing feature of atherosclerotic cardiovascular disease in CKD is the severity of the disease, which is reflective of an increase in inflammatory mediators and vascular calcification secondary to hyperparathyroidism of renal origin that are unique to patients with CKD. Additional components of atherosclerotic cardiovascular disease that are prominent in patients with CKD include microvascular disease and myocardial fibrosis. Therapeutic interventions that minimize cardiovascular events related to atherosclerotic cardiovascular disease in patients with CKD, as determined by well-designed clinical trials, are limited to statins. Data are lacking regarding other available therapeutic measures primarily due to exclusion of patients with CKD from major trials studying cardiovascular disease. Data from well-designed randomized controlled trials are needed to guide clinicians who care for this high-risk population in the management of atherosclerotic cardiovascular disease to improve clinical outcomes.

    Multiple factors are involved in the etiology of cardiovascular disease (CVD). Pathological changes occur in a variety of cell types long before symptoms become apparent and diagnosis is made. Dysregulation of physiological functions are associated with the activation of immune cells, leading to local and finally systemic inflammation that is characterized by production of high levels of reactive oxygen species (ROS). Patients suffering from inflammatory diseases often present with diminished levels of antioxidants either due to insufficient dietary intake or, and even more likely, due to increased demand in situations of overwhelming ROS production by activated immune effector cells like macrophages. Antioxidants are suggested to beneficially interfere with diseases-related oxidative stress, however the interplay of endogenous and exogenous antioxidants with the overall redox system is complex. Moreover, molecular mechanisms underlying oxidative stress in CVD are not fully elucidated. Metabolic dybalances are suggested to play a major role in disease onset and progression. Several central signaling pathways involved in the regulation of immunological, metabolic and endothelial function are regulated in a redox-sensitive manner. During cellular immune response, interferon γ-dependent pathways are activated such as tryptophan breakdown by the enzyme indoleamine 2,3-dioxygenase (IDO) in monocyte-derived macrophages, fibroblasts, endothelial and epithelial cells. Neopterin, a marker of oxidative stress and immune activation is produced by GTP-cyclohydrolase I in macrophages and dendritic cells. Nitric oxide synthase (NOS) is induced in several cell types to generate nitric oxide (NO). NO, despite its low reactivity, is a potent antioxidant involved in the regulation of the vasomotor tone and of immunomodulatory signaling pathways. NO inhibits the expression and function of IDO. Function of NOS requires the cofactor tetrahydrobiopterin (BH4), which is produced in

    Progressive aging induces several structural and functional alterations in the cardiovascular system, among whom particularly important are a reduced number of myocardial cells and increased interstitial collagen fibers, which result in impaired left ventricular diastolic function. Even in the absence of cardiovascular disease, aging is strongly associated to a age-related reduced maximal aerobic capacity. This is due to a variety of physiological changes both at central and at peripheral level. Physical activity (PA) appears in general to have a positive effect on several health outcomes in the elderly. This review aims to illustrate the beneficial effects of exercise on the physiologic decline of cardiovascular performance occurring with age. Furthermore, it will be stressed also the positive effect of physical activity in elderly patients affected by cardiovascular diseases, such as heart failure and hypertension, and multiple comorbidities which may significantly worse prognosis in this high risk population.

    Cardiovascular diseases are the leading cause of death worldwide. Literature data indicate that, due to these diseases, approximately 17.5 million people died in 2012. Types of cardiovascular disease include ischemic heart disease, cerebrovascular disease, peripheral vascular disease, congenital heart disease, rheumatic heart disease, cardiomyopathy and arrhythmia. Proper nutrition is an important factor in reducing the risk of cardiovascular events. An interesting element of our diets is spices. For thousands of years, they have been used in the treatment of many diseases: bacterial infections, coughs, colds, and liver diseases. Many studies also demonstrate their antioxidant, chemopreventive, anti-inflammatory and immunomodulatory properties. This paper focuses on discussing the importance of selected spices (garlic, cinnamon, ginger, coriander and turmeric) in the prevention and treatment of cardiovascular diseases.

    2010-10-01

    Atherosclerotic cardiovascular disease (CVD) is the most common cause of death worldwide. Usually atherosclerosis is caused by the combined effects of multiple risk factors. For this reason, most guidelines on the prevention of CVD stress the assessment of total CVD risk. The most intensive risk factor modification can then be directed towards the individuals who will derive the greatest benefit. To assist the clinician in calculating the effects of these multiple interacting risk factors, a number of risk estimation systems have been developed. This review address several issues regarding total CVD risk assessment: Why should total CVD risk be assessed? What risk estimation systems are available? How well do these systems estimate risk? What are the advantages and disadvantages of the current systems? What are the current limitations of risk estimation systems and how can they be resolved? What new developments have occurred in CVD risk estimation?

    Cardiovascular morbidity and mortality are increased in acromegaly. In fact, GH and IGF-I excess induces a specific cardiomyopathy. The early stage of acromegaly is characterized by the hyperkinetic syndrome (high heart rate and increased systolic output). Frequently, concentric biventricular hypertrophy and diastolic dysfunction occur in acromegaly, leading to an impaired systolic function ending in heart failure if the disease is untreated or unsuccessfully untreated. Besides, abnormalities of cardiac rhythm and of valves have been also described in acromegaly. The coexistence of other complications, such as arterial hypertension and diabetes, aggravates the acromegalic cardiomyopathy. The suppression of GH/IGF-I following an efficacious therapy could decrease left ventricular mass and improve cardiac function. In conclusion, a careful evaluation of cardiac function, morphology and activity seems to be mandatory in acromegaly.

    We present an investigation of the occurrence of cardiovascular disease in patients with diabetes in Denmark 2000 through 2011. The Diabetes Impact Study 2013 is based on all registrants in the Danish National Diabetes Register as of July 3rd 2013 (n=497,232). Record linkage with the Danish...... of diabetes has been rather constant at higher level in males (around 16-18%) than in females (around 12-14%) during 2000-2011 (incl.). In contrast, the incidence rate of CVD after having diabetes diagnosis has declined from about 4.5 to less than 3 during the same period, with higher declining level...... for males than for females. Efforts to detect diabetes at an earlier stage have not resulted in a reduced occurrence of CVD at the diagnosis of diabetes in Denmark. However, the risk of developing CVD after the diagnosis of diabetes has been declining, possibly reflecting benefits of intensified treatment...

  1. Cardiovascular Magnetic Resonance Imaging

    2000-03-01

    Cardiovascular diseases are a major source of morbidity and mortality in the United States. Early detection of disease can often be used to improved outcomes, either through direct interventions (e.g. surgical corrections) or by causing the patient to modify his or her behavior (e.g. smoking cessation or dietary changes). Ideally, the detection process should be noninvasive (i.e. it should not be associated with significant risk). Magnetic Resonance Imaging (MRI) refers to the formation of images by localizing NMR signals, typically from protons in the body. As in other applications of NMR, a homogeneous static magnetic field ( ~0.5 to 4 T) is used to create ``longitudinal" magnetization. A magnetic field rotating at the Larmor frequency (proportional to the static field) excites spins, converting longitudinal magnetization to ``transverse" magnetization and generating a signal. Localization is performed using pulsed gradients in the static field. MRI can produce images of 2-D slices, 3-D volumes, time-resolved images of pseudo-periodic phenomena such as heart function, and even real-time imaging. It is also possible to acquire spatially localized NMR spectra. MRI has a number of advantages, but perhaps the most fundamental is the richness of the contrast mechanisms. Tissues can be differentiated by differences in proton density, NMR properties, and even flow or motion. We also have the ability to introduce substances that alter NMR signals. These contrast agents can be used to enhance vascular structures and measure perfusion. Cardiovascular MRI allows the reliable diagnosis of important conditions. It is possible to image the blood vessel tree, quantitate flow and perfusion, and image cardiac contraction. Fundamentally, the power of MRI as a diagnostic tool stems from the richness of the contrast mechanisms and the flexibility in control of imaging parameters.

    The effect of organ injury severity on outcome was assessed in 101 patients treated for duodenal trauma. Most patients were men (89%) and victims of penetrating wounds (93%). Grade I is minor hematoma or incomplete perforation; Grade II is major hematoma or small complete perforation; Grade III is large perforation excluding ampulla; Grade IV is large perforation at ampulla; Grade V is duodenopancreatic crunch. The injuries were as follows: Grade I (5 patients), Grade II (31), Grade III (40), Grade IV (12), and Grade V (13). Fourteen patients exsanguinated from associated vessel injury; each had Grade IV or Grade V injury. All 36 patients with Grade I and Grade II injury had primary repair; the single death was due to liver necrosis. Most (31 patients) Grade III injuries and three Grade IV injuries were treated by primary repair alone; the three deaths were unrelated to the duodenal injury. Other major injuries were treated by duodenal exclusion (4 patients), duodenal diverticulization (6), or resection (4); the single death was unrelated to the duodenum. Primary closure is favored for minor injuries and most Grade III injuries. Severe injuries may require exclusion, diverticulization, or resection.

    Cardiovascular system failure is commonly faced by the intensivist. Heart failure can occur due to a host of predisposing cardiac disorders or as secondary effects of systemic illness. When the heart is unable to provide an adequate cardiac output to maintain adequate tissue perfusion, cardiogenic shock ensues. Without prompt diagnosis and appropriate management, these patients have significant morbidity and mortality, with in-hospital mortality approaching 60% for all age groups. Accurate and rapid identification of cardiogenic shock as a medical emergency, with expeditious implementation of appropriate therapy, can lead to improved clinical outcomes. In this review, we discuss optimal strategies for diagnosis and monitoring of cardiogenic shock. We discuss the diverse therapeutic strategies employed for cardiogenic shock, including pharmacological (e.g., vasoactive agents, fibrinolytic agents), mechanical (e.g., intraaortic balloon pumps, left ventricular assist devices, percutaneous coronary intervention [PCI]), and surgical approaches such as coronary artery bypass graft (CABG), valvular repair or replacement (e.g., for acute mitral regurgitation, ventricular septal rupture, or free wall rupture).

    Basketball is a popular, worldwide sport played outdoors and indoors year-round. Patterns of injury are related to abrupt changes in the athlete's direction, jumping, contact between athletes, the hard playing surface and paucity of protective equipment. Intensity of play and training in the quest of scholarships and professional careers is believed to contribute to an increasing occurrence of injury. Radiologists' appreciation of the breadth of injury and its relation to imaging and clinical findings should enhance the care of these children. Some of the patterns of injury are well known to radiologists but vary due to age- and size-related changes; the growing skeleton is affected by differing susceptibilities from biomechanical stresses at different sizes. Beyond screening radiographs, the accuracy of MRI and CT has improved diagnosis and treatment plans in this realm. Investigations to detect symptoms and signs in an attempt to prevent the tragedy of sudden cardiac death in basketball players may lead to MRI and CTA studies that compel radiologists to evaluate cardiac function along with myocardial and coronary artery anatomy. Worthy of mention also is the female athlete triad of disordered eating, amenorrhea, and osteoporosis that is observed in some young women participating in this and other sports. (orig.)

    ObjectiveTo evaluate the effect of dexmedetomidine on the quality of emergence from general anesthesia in the elderly traumatic brain injury patients with cardiovascular disease.MethodsA total of 88 ASA Ⅰ~Ⅱpatients were randomly divided the dexmedetomidine group and the control group with 44 patients in each. The dexmedetomidine group was given dexmedetomidine at an initial dose of 1.0 μg /kg over 15 minutes,followed by a continuous infusion of 0.6 μg/kg per hours until 30 min before the end of surgery,the control group was given normal instead. General anesthesia were used in the two groups. The recovery of anesthesia,analgesic effective situation,adverse reaction,visual analogue scale(VAS)and Ramsay sedation score after extubation,epinephrine(E),norepinephrine(NE)and endothelin 1(ET-1) between two groups were compared.ResultsThe rate of effective analgesia in the dexmedetomidine group was significantly higher than the control group(χ2=5.61,P<0.05). The scores of VAS in the dexmedetomidine group were lower than the control group at 5 min,30 min,60 min,120 min after extubation(t=3.21,2.87,4.14,3.63,P<0.05). The scores of Ramsay sedation in the dexmedetomidine group were higher than the control group at 5 min,30 min,60 min after extubation(t=1.49,4.53,3.81,P<0.05). The incidence of restlessness,chills,cough,nausea and vomiting in the dexmedetomidine group were significantly lower than the control group(χ2=3.21,4.53,1.79,2.43,P<0.05). The levels of serum E,NE and ET-1 in the dexmedetomidine group were significantly lower than the control group at 2 h,4 h,12 h and 24 h after operation(t= 3.21,3.02,3.61,4.15, 3.89,3.15,4.52,3.37,3.58,4.62,4.74,3.71,P<0.05).

    Romero, Vivian Carolina; Pearlman, Mark

    2012-02-01

    Maternal mortality is an important indicator of adequacy of health care in our society. Improvements in the obstetric care system as well as advances in technology have contributed to reduction in maternal mortality rates. Trauma complicates up to 7% of all pregnancies and has emerged as the leading cause of maternal mortality, becoming a significant concern for the public health system. Maternal mortality secondary to trauma can often be prevented by coordinated medical care, but it is essential that caregivers recognize the unique situation of providing simultaneous care to 2 patients who have a complex physiologic relationship. Optimal management of the pregnant trauma victim requires a multidisciplinary team, where the obstetrician plays a central role. This review focuses on the incidence of maternal mortality due to trauma, the mechanisms involved in traumatic injury, the important anatomic and physiologic changes that may predispose to mortality due to trauma, and finally, preventive strategies that may decrease the incidence of traumatic maternal death.

    Full Text Available Christopher Barone, Shaymaa S Mousa, Shaker A MousaThe Pharmaceutical Research Institute, Albany College of Pharmacy and Health Sciences, Albany, NY, USAAbstract: Some of the most commonly prescribed medications are those for cardiovascular maladies. The beneficial effects of these medications have been well documented. However, there can be substantial variation in response to these medications among patients, which may be due to genetic variation. For this reason pharmacogenomic studies are emerging across all aspects of cardiovascular medicine. The goal of pharmacogenomics is to tailor treatment to an individual’s genetic makeup in order to improve the benefit-to-risk ratio. This review examines the potential pharmacogenomic parameters which may lead to a future of personalized medicine. For example, it has been found that patients with CYP2C9 and VKORC1 gene variations have a different response to warfarin. Other studies looking at β-blockers, ACE inhibitors, ARBs, diuretics and statins have shown some results linking genetic variations to pharmacologic response. However these studies have not impacted clinical use yet, unlike warfarin findings, as the small retrospective studies need to be followed up by larger prospective studies for definitive results.Keywords: cardiovascular, pharmacogenomics, genetics, cardiovascular medicine, personalized medicine, polymorphism

    Full Text Available Cocaine is used by more than 14 million people worldwide, about 0.3 percent of the global population age is 15 to 64 years. After alcohol, cocaine is the most common cause of acute drug-related emergency department visits in the United States. Cocaine consumption is more frequently associated with acute cardiovascular illness.  Cocaine stimulates α1, α2, β1 and β2 adrenergic receptors through increased levels of norepinephrine and a lesser extent epinephrine. The cardiovascular effects of cocaine are thought to be similar and regardless to the route of consumption. An acute coronary syndrome is the most common cardiac problem including myocardial ischemia and infarction even in young persons without atherosclerosis, aortic dissection and rupture, arrhythmias, ventricular tachycardia and fibrillation, asystole and finally sudden death. Other cardiovascular effects that caused by cocaine include coronary artery aneurysm, palpitation, sinus tachycardia, increased systemic vascular resistance and hypertension crisis, left ventricular hypertrophy, myocarditis, cardiomyopathy, myocardial fibrosis, bundle branch block, heart block, supraventricular arrhythmia, accelerated atherosclerosis, hypotension, bradycardia and infective endocarditis  among intravenous users.Cocaine by three mechanisms cause ischemia: 1. increased myocardial oxygen demand, 2. decreased coronary blood flow due to coronary artery vasoconstriction and spasm and 3. Coronary artery thrombosis via activation of platelets, stimulation of platelet aggregation and potentiation of thromboxane production.

    Full Text Available Fraser D RussellSchool of Health and Sport Sciences, Faculty of Science, Health and Education, University of the Sunshine Coast, Sippy Downs, Queensland, AustraliaAbstract: Cardiovascular function is modulated by neuronal transmitters, circulating hormones, and factors that are released locally from tissues. Urotensin II (UII is an 11 amino acid peptide that stimulates its’ obligatory G protein coupled urotensin II receptors (UT to modulate cardiovascular function in humans and in other animal species, and has been implicated in both vasculoprotective and vasculopathic effects. For example, tissue and circulating concentrations of UII have been reported to increase in some studies involving patients with atherosclerosis, heart failure, hypertension, preeclampsia, diabetes, renal disease and liver disease, raising the possibility that the UT receptor system is involved in the development and/or progression of these conditions. Consistent with this hypothesis, administration of UT receptor antagonists to animal models of cardiovascular disease have revealed improvements in cardiovascular remodelling and hemodynamics. However, recent studies have questioned this contributory role of UII in disease, and have instead postulated a protective effect on the cardiovascular system. For example, high concentrations of circulating UII correlated with improved clinical outcomes in patients with renal disease or myocardial infarction. The purpose of this review is to consider the regulation of the cardiovascular system by UII, giving consideration to methodologies for measurement of plasma concentrations, sites of synthesis and triggers for release.Keywords: urotensin II, cardiovascular disease, heart failure, hypertension

    Undergraduates students in 12 courses at 8 different institutions were surveyed to determine the prevalence of 13 different misconceptions (conceptual difficulties) about cardiovascular function. The prevalence of these misconceptions ranged from 20 to 81% and, for each misconception, was consistent across the different student populations. We also obtained explanations for the students' answers either as free responses or with follow-up multiple-choice questions. These results suggest that students have a number of underlying conceptual difficulties about cardiovascular phenomena. One possible source of some misconceptions is the students' inability to apply simple general models to specific cardiovascular phenomena. Some implications of these results for teachers of physiology are discussed.

    Fish patients with cardiovascular disorders present a challenge in terms of diagnostic evaluation and therapeutic options. Veterinarians can approach these cases in fish using methods similar to those employed for other companion animals. Clinicians who evaluate and treat fish in private, aquarium, zoologic, or aquaculture settings need to rely on sound clinical judgment after thorough historical and physical evaluation. Pharmacokinetic data and treatments specific to cardiovascular disease in fish are limited; thus, drug types and dosages used in fish are largely empiric. Fish cardiovascular anatomy, physiology, diagnostic evaluation, monitoring, common diseases, cardiac pathologic conditions, formulary options, and comprehensive references are presented with the goal of providing fish veterinarians with clinically relevant tools.

    Epidemiological studies indicate that hyperuricaemia is an independent risk factor for cardiovascular disease. Alongside uric acid formation, increased xanthine oxidase activity also results in the formation of oxidative free radicals and superoxide particles. Oxidative stress significantly contributes to the development of cardiovascular disease, including endothelial cell dysfunction, atherosclerosis, vascular calcification and impaired myocardial energetics. Allopurinol, a competitive xanthine oxidase inhibitor, in addition to reducing serum uric acid levels, can act as a free radical scavenger. Although traditionally used for the management of gout, there has been renewed interest in the role of allopurinol in the management of cardiovascular disease. In this review, we summarise the role of the xanthine oxidase pathway in the generation of oxidative stress and evaluate the current body of evidence assessing the clinical effects of allopurinol in patients with cardiovascular disease. A number of small clinical studies have shown a beneficial effect of allopurinol in reducing ischemia-reperfusion injury in the setting of bypass surgery and coronary angioplasty. Additionally, studies in heart failure indicate a potential favourable effect of allopurinol on endothelial dysfunction, LV function and haemodynamic indices, particularly in those with raised serum uric acid levels. Whilst this cheap and readily available pharmacological option may offer a very cost effective therapeutic option, large-scale prospective studies are required to better delineate its role in reducing hard clinical end-points.

    Cardiovascular disease (CVD) is the main cause of death in Western countries. Nutrition has a significant role in the prevention of many chronic diseases such as CVD, cancers, and degenerative brain diseases. The major risk and protective factors in the diet are well recognized, but interesting new candidates continue to appear. It is well known that a greater intake of fruit and vegetables can help prevent heart diseases and mortality. Because fruit, berries, and vegetables are chemically complex foods, it is difficult to pinpoint any single nutrient that contributes the most to the cardioprotective effects. Several potential components that are found in fruit, berries, and vegetables are probably involved in the protective effects against CVD. Potential beneficial substances include antioxidant vitamins, folate, fiber, and potassium. Antioxidant compounds found in fruit and vegetables, such as vitamin C, carotenoids, and flavonoids, may influence the risk of CVD by preventing the oxidation of cholesterol in arteries. In this review, the role of main dietary carotenoids, ie, lycopene, beta-carotene, alpha-carotene, beta-cryptoxanthin, lutein, and zeaxanthin, in the prevention of heart diseases is discussed. Although it is clear that a higher intake of fruit and vegetables can help prevent the morbidity and mortality associated with heart diseases, more information is needed to ascertain the association between the intake of single nutrients, such as carotenoids, and the risk of CVD. Currently, the consumption of carotenoids in pharmaceutical forms for the treatment or prevention of heart diseases cannot be recommended.

    Background The Drug-Induced Liver Injury Network (DILIN) studies hepatotoxicity due to conventional medications as well as herbals and dietary supplements (HDS). Rationale To characterize hepatotoxicity and its outcomes from HDS versus medications, patients with hepatotoxicity attributed to medications or HDS were enrolled prospectively between 2004 and 2013. The study took place among eight US referral centers that are part of the DILIN. Consecutive patients with liver injury referred to a DILIN center were eligible. The final sample comprised 130 (15.5%) of all subjects enrolled (839) who were judged to have experienced liver injury due to HDS. Hepatotoxicity due to HDS was evaluated by expert opinion. Demographic and clinical characteristics and outcome assessments including death and liver transplantation were ascertained. Cases were stratified and compared according to the type of agent implicated in liver injury; 45 had injury due to bodybuilding HDS, 85 due to non-bodybuilding HDS, and 709 due to medications. Main Results Liver injury due to HDS increased from 7% to 20% (p Bodybuilding HDS caused prolonged jaundice (median 91 days) in young men but did not result in any fatalities or liver transplantation. The remaining HDS cases presented as hepatocellular injury, predominantly in middle-aged women and more frequently led to death or transplantation compared to injury from medications (13% vs. 3%, p bodybuilding HDS is more severe than from bodybuilding HDS or medications, as evidenced by differences in unfavorable outcomes; death and transplantation.

    Injuries constitute a leading cause of morbidity and mortality in the world, with intentional injuries and those related to traffic most important, due to their social impact and high prevalence. Although alcohol consumption has been identified as a risk factor for injuries, few studies have assessed risk separately for intentional injuries and unintentional injuries caused by traffic, and by other causes. The objective of this paper was to estimate the risk of injuries after acute alcohol consumption for intentional injuries and unintentional traffic and non-traffic injuries, using, alternatively, two exposure measures: self-reported drinking prior to the event and blood alcohol concentration. A probability sample was collected of 540 patients from the emergency department of a hospital in Argentina. Logistic regressions were performed, with and without adjusting for gender, age and drinking pattern. Higher risks were found when blood alcohol concentration was used as a measure of consumption, compared to self-report. The highest risk estimates were obtained for intentional injuries, followed by unintentional traffic and, lastly, by unintentional non-traffic injuries. After controlling for confounders, risks for intentional and unintentional traffic injuries appeared similar for those above and below the legal limit. Results point to a significant involvement of alcohol in the regional context.

  7. Does treatment of SDB in children improve cardiovascular outcome?

    Science.gov (United States)

    Vlahandonis, Anna; Walter, Lisa M; Horne, Rosemary S C

    2013-02-01

    Sleep disordered breathing (SDB) is a common disorder in both adults and children and is caused by the obstruction of the upper airway during sleep. Unlike adults, most cases of paediatric SDB are due to the presence of enlarged tonsils and adenoids, thus the main treatment option is adenotonsillectomy (T&A). It is well known that obstructive sleep apnoea in adults increases the risk for hypertension, coronary artery disease and stroke, and there is now mounting evidence that SDB also has a significant impact on the cardiovascular system in children with reports of elevated blood pressure, endothelial dysfunction and altered autonomic cardiovascular control. As there is now substantial evidence that elevated blood pressure in childhood is carried on to adulthood it is important to know if treatment of SDB improves cardiovascular outcomes. Studies in adults have shown that treatment of SDB leads to improvements in cardiovascular function, including a reduction in pulmonary artery pressure, systemic blood pressure and endothelial dysfunction. However, studies exploring the outcomes of treatment of SDB in children on the cardiovascular system are limited and varied in their methodology and outcome measures. As a number of cardiovascular disturbances are sequelae of SDB, early detection and management could result in the reduction of elevated blood pressure in children, and consequently a reduction in cardiovascular morbidity in adulthood. The aim of this review is to summarise the findings of studies to date which have investigated the cardiovascular outcomes in children treated for SDB and to make recommendations for future management of this very common disease.

    Objetivos: Valorar si el hipotiroidismo subclínico puede comportarse como un factor de riesgo cardiovascular o un modificador del mismo, identificando variables epidemiológicas y riesgo cardiovascular estimado en una muestra de sujetos diagnosticados en la provincia de Albacete. Método: Estudio observacional, descriptivo y transversal realizado en Albacete durante la primera quincena de enero de 2012 en pacientes de ambos géneros con hipotiroidismo subclínico. Se analizaron las siguientes variables: glucemia basal, colesterol total, colesterol HDL, colesterol LDL, triglicéridos, TSH, T4, peso, talla, I.M.C., tensión arterial, antecedentes de patología cardiovascular, factores de riesgo cardiovascular y riesgo cardiovascular estimado. Resultados: Se obtuvieron 326 pacientes, con predominio femenino (79,2 %), menores de 65 años en el 78% y sin factores de riesgo cardiovascular en el 48,61%. La prevalencia de los factores de riesgo cardiovascular identificados fué: tabaquismo (33,2%), diabetes mellitus (24,9%), hipertensión arterial (23,4%), alteraciones lipídicas (28,9%) y fibrilación auricular (4,9 %). No se encontró asociación entre hipotiroidismo subclínico y la mayoría de los parámetros del perfil lipídico que condicionan un perfil pro-aterogénico, salvo con la hipertrigliceridemia. Asimismo, tampoco se constató asociación con riesgo cardiovascular aumentado. Conclusiones: El perfil del paciente con hipotiroidismo subclínico es una mujer de mediana edad sin factores de riesgo cardiovascular en la mitad de casos. Se ha encontrado relación entre hipotiroidismo subclínico e hipertrigliceridemia, pero no con el resto de parámetros del perfil lipídico, otros factores de riesgo cardiovascular o con aumento de dicho riesgo. Sin embargo, un 25% de diabéticos y un 22% de no diabéticos están en situación de riesgo cardiovascular moderado-alto.

    2015-01-01

    Cardiovascular mortality has remained high in patients on peritoneal dialysis (PD) due to the high prevalence of various cardiovascular complications including coronary artery disease, left ventricular hypertrophy and dysfunction, heart failure, arrhythmia (especially atrial fibrillation), cerebrovascular disease, and peripheral arterial disease. In addition, nearly a quarter of PD patients develop sudden cardiac death as the terminal life event. Thus, it is essential to identify effective treatment that may lower cardiovascular mortality and improve survival of PD patients. The International Society for Peritoneal Dialysis (ISPD) commissioned a global workgroup in 2012 to formulate a series of recommendation statements regarding lifestyle modification, assessment and management of various cardiovascular risk factors, and management of the various cardiovascular complications to be published in 2 guideline documents. This publication forms the second part of the guideline documents and includes recommendation statements on the management of various cardiovascular complications in adult chronic PD patients. The documents are intended to serve as a global clinical practice guideline for clinicians who look after PD patients. We also define areas where evidence is clearly deficient and make suggestions for future research in each specific area.

    Vitamin D plays a classical hormonal role in skeletal health by regulating calcium and phosphorus metabolism. Vitamin D metabolites also have physiological functions in nonskeletal tissues, where local synthesis influences regulatory pathways via paracrine and autocrine mechanisms. The active metabolite of vitamin D, 1α,25-dihydroxyvitamin D, binds to the vitamin D receptor that regulates numerous genes involved in fundamental processes of potential relevance to cardiovascular disease, including cell proliferation and differentiation, apoptosis, oxidative stress, membrane transport, matrix homeostasis, and cell adhesion. Vitamin D receptors have been found in all the major cardiovascular cell types including cardiomyocytes, arterial wall cells, and immune cells. Experimental studies have established a role for vitamin D metabolites in pathways that are integral to cardiovascular function and disease, including inflammation, thrombosis, and the renin-angiotensin system. Clinical studies have generally demonstrated an independent association between vitamin D deficiency and various manifestations of degenerative cardiovascular disease including vascular calcification. However, the role of vitamin D supplementation in the management of cardiovascular disease remains to be established. This review summarizes the clinical studies showing associations between vitamin D status and cardiovascular disease and the experimental studies that explore the mechanistic basis for these associations.

    Haber, Guy; Witberg, Guy; Danenberg, Haim

    2007-10-01

    Cardiovascular atherothrombosis is the most common cause of death globally, with several well-known risk factors. Air pollution is a byproduct of fuel combustion by motor vehicles, power plants and industrial factories. It is composed of gases, fluids and particulate matter (PM) of different sizes, which include basic carbon, organic carbonic molecules and metals such as vanadium, nickel, zinc and iron. These particles are subdivided by their median size, a major contributing factor for their capability to enter the human body through the respiratory system. Most of the epidemiological studies have shown correlation between acute and long-term exposure to air pollution elements and cardiovascular morbidity in general, and angina pectoris and acute myocardial infarction specifically. Physiological studies have found different arrhythmias as the etiologic cause of cardiovascular morbidity and mortality following exposure to air pollution. A major finding was a decline in heart rate variability, a phenomenon known as endangering for cardiovascular morbidity and mortality, especially in patients after acute myocardial infarction. To date, several pathways have been proposed, including a hypercoagulable state following an inflammatory response, cardiac nervous autonomic disequilibrium, endothelial dysfunction with blood vessel contraction and direct toxic impact on cardiac muscle. Additional research is needed for clarifying the pathophysiological pathways by which air pollution affects the cardiovascular system. That might allow forthcoming with preventive measures and correct treatment, and hence a decrease in cardiovascular morbidity and mortality. Another important target is dose-outcome correlation curves for safety threshold calculation as a basis for air pollution regulations.

    2016-05-01

    The purpose of this study was to study whether allergen exposure can induce inflammation and lower the anti-inflammation levels in serum and in adipose tissues, and further develop cardiovascular injury. Our data showed that heart rate was significantly higher in the OVA-challenged mice compared to control mice. Moreover, there were higher expressions of pro-inflammation genes in the OVA-challenged mice in adipose tissues, and the expressions of anti-inflammation genes were lower. The levels of inflammation mediators were associated in serum and adipose tissues. The level of circulatory injury lactate dehydrogenase was significantly associated with the levels of E-selectin, resistin and adiponectin in the serum. The hematoxylin and eosin and immunohistochemistry stains indicated the OVA-challenged mice had higher levels of inflammation. In summary, the current study demonstrated allergen exposure can cause cardiovascular injury, and inflammatory mediators in adipose tissues play an important role in the pathogenesis of cardiovascular injury.

    Cardiovascular magnetic resonance and computed tomography have evolved as very practical and useful techniques applied in clinical cardiology. Due to their rapid acceptance in the cardiology community and widespread use, training of both cardiologists and radiologists on this subspecialty has not been homogeneous so far. This in part explains significant differences observed in the diverse background found in today’s practicing physicians who execute these exams. In order to guide training facilities as well as both payers, contractors and general cardiologists ordering the exam, this document provides a minimum standard that should be accomplished by all physicians who pursue education in the field and for those who already practice in it. The clinical competences listed in this statement are by no means thorough but should be required by all those involved in cardiovascular magnetic resonance and computed tomography as the customary requirements for current and future practitioners.

  2. Cardiovascular pharmacogenetics in the SNP era.

    2003-07-01

    In the past pharmacological agents have contributed to a significant reduction in age-adjusted incidence of cardiovascular events. However, not all patients treated with these agents respond favorably, and some individuals may develop side-effects. With aging of the population and the growing prevalence of cardiovascular risk factors worldwide, it is expected that the demand for cardiovascular drugs will increase in the future. Accordingly, there is a growing need to identify the 'good' responders as well as the persons at risk for developing adverse events. Evidence is accumulating to indicate that responses to drugs are at least partly under genetic control. As such, pharmacogenetics - the study of variability in drug responses attributed to hereditary factors in different populations - may significantly assist in providing answers toward meeting this challenge. Pharmacogenetics mostly relies on associations between a specific genetic marker like single nucleotide polymorphisms (SNPs), either alone or arranged in a specific linear order on a certain chromosomal region (haplotypes), and a particular response to drugs. Numerous associations have been reported between selected genotypes and specific responses to cardiovascular drugs. Recently, for instance, associations have been reported between specific alleles of the apoE gene and the lipid-lowering response to statins, or the lipid-elevating effect of isotretinoin. Thus far, these types of studies have been mostly limited to a priori selected candidate genes due to restricted genotyping and analytical capacities. Thanks to the large number of SNPs now available in the public domain through the SNP Consortium and the newly developed technologies (high throughput genotyping, bioinformatics software), it is now possible to interrogate more than 200,000 SNPs distributed over the entire human genome. One pharmacogenetic study using this approach has been launched by GlaxoSmithKline to identify the approximately 4% of

    The aim of this study is to declare our experience and to identify the important factors that influence the mortality and morbidity in patients with combat-related penetrating wounds of the abdomen (CR-PWA) with major venous vessel injuries. Twenty-six wounded with combat-related injuries of major abdominal venous vessels, admitted in the University Clinic cardiovascular surgery department during the period from 1 August 1991 through 30 October 1995, were analyzed. Patients with concomitant injured arteries and extra-abdominal injuries (n=150; 85.2%) were excluded from this study. The Penetrating Abdominal Trauma Index (PATI) score for each patient was calculated. Fifteen patients (57.69%) sustained with PATI score greater than 25 died. The mean duration of hospitalization was 16 days (range 0-86). The average hospitalization time for those surviving their complications was 17 days with a PATI of 25 or less, and 43 days with a score more than 25. Three clinical assessments of the long-term outcome were performed after a median of about 3, 5 and 10 years, respectively. Surviving patients (42.31%) were symptom free and had normal Duplex scans as well as no other surgical related complications. Higher PATI scores, postoperative complications and reoperations exert an unfavorable effect on patient outcome.

    Celiac trunk injures are rare events, with high mortality rates and difficult management. Endovascular treatment may be considered to avoid bleeding. We report a case of severe bleeding in a 37-year-old man resulting from celiac trunk stretching after a motorcycle crash. Because direct celiac trunk catheterization was not possible, a retrograde catheterization of the common hepatic artery was performed via the superior mesenteric artery. Two vascular plugs (type IV) were released, and the exclusion of the celiac trunk origin was completed with the deployment of an aortic cuff. The patient's clinical condition immediately improved, and after 6 months' follow-up, imaging confirmed the complete exclusion of the celiac trunk.

    By accident a 12 year old boy had to spend 4 hours in a SO/sub 2/-enriched atmosphere (concentration 13.8 mg per cubicmeter = 4.8 ppm). The course of the following intoxication was tetraphasic: 1. acute irritation of the mucous membranes of the upper airways and of the eye: rhinopharyngitis, laryngitis and bronchitis, conjunctivitis and corneal lesions (duration: 5 days), 2. symptom free interval (duration: 3 days), 3. subacute destruction of the low airways and the lung: destructing bronchitis, bronchiolitis, alveolitis, emphysema of the lung, mediastinum and skin, gradual development of bronchiectasis (duration: 9-12 months) and 4. gradual transition into terminal scarification: emphysema of the lung, continuous partial respiratory insufficiency with combined, especially obstructive disturbance of ventilation (without alterations observed during the last 4 years). On occasions of this fateful and therapeutically hardly influenced course recommendations are given for initial general and topical administration of very high doses of corticosteroids in each case of inhalative intoxication as the only measure which probably would have prevented it.

    Full Text Available Background: cardiovascular hyperreactivity in young people has been associated with different risk factors and a family history of hypertension. Objective: to determine the association between a family history of hypertension and cardiovascular risk factors with cardiovascular hyperreactivity. Method: a correlational, cross-sectional study was conducted in a universe of 77 young individuals aged 18 to 40 years from the Churuguara parish of the Falcon State in Venezuela. The variables were: age, sex, skin color, family history of hypertension, medical history of hypertension, diabetes mellitus, alcohol consumption, salt intake, physical activity and body mass index. The diastolic and systolic blood pressure before and after the pressor response elicited by an isometric exercise were determined as hemodynamic variables. Results: thirteen percent of the participants developed vascular reactivity after the hand-held weight test. Cardiovascular hyperreactivity is three times higher in individuals with a family history of hypertension. Sixty percent of those with a body mass index greater than or equal to 27 kg/m2 are hyperreactive. There is a higher cardiovascular response to the hand-held weight test as the consumption of alcohol increases. Thirty three point three percent of the participants who smoke are hyperreactive. Conclusions: there is a significant association between a family history of hypertension, obesity, salt intake, alcohol consumption and vascular hyperreactivity.

    It has been shown that the consumption of cocoa has a positive influence on a number of cardiovascular surrogate parameters such as arterial vasodilatation and a moderate decrease in blood pressure in humans. In the blood, a decrease in platelet aggregation and an increase in angiogenetic progenitor cells was noted. Furthermore, anti-inflammatory effects, an amelioration of the lipid profile and glucose metabolism was described. An increase of endothelial NO production following the ingestion of the antioxidant cocoa flavanols catechin and epicatechin seems to be the leading mechanism causing these effects. In animal studies of myocardial reperfusion, a decrease in infarct size was noted. In several prospective cohort studies from Europe and the United States, a 50 % reduction of mortality mostly due to a reduction of myocardial infarction was published. Consumption up to about 25 g daily of a flavanol rich dark chocolate (ca. 85 % cocoa content) can be recommended for cardiovascular prevention. In this moderate dosage, the potentially harmful effects due to weight gain and cadmium intake will be minimal. However, controlled randomized trials with well defined clinical endpoints are needed to prove the positive effects described so far. At this point, in time based on the information described in this article, a moderate consumption of flavanol rich cocoa products seems to be effective in the prevention of coronary artery disease and myocardial infarction.

This condition often leads to metabolic syndrome, which increases the risk of cardiovascular disease. A large number of studies have been carried out to understand the pathogenesis of cardiovascular dysfunction in obese patients. Endothelial dysfunction plays a key role in the progression of atherosclerosis and the development of coronary artery disease, hypertension and congestive heart failure. Noninvasive methods in the field of cardiovascular imaging, such as measuring intima-media thickness, flow-mediated dilatation, tissue Doppler, and strain, and strain rate, constitute new tools for the early detection of cardiac and vascular dysfunction. These techniques will certainly enable a better evaluation of initial cardiovascular injury and allow the correct, timely management of obese patients. The present review summarizes the main aspects of cardiovascular dysfunction in obesity and discusses the application of recent noninvasive imaging methods for the early detection of cardiovascular alterations.Keywords: cardiovascular risk, endothelium dysfunction, obesity, strain and strain rate, tissue Doppler

El año 2009 los peatones fueron involucrados en 27% de los accidentes de tránsito en el Perú. Este es un problema significativo para la salud pública del país, pues tiene repercusiones económicas importantes. En este artículo se revisa la evidencia disponible para algunas intervenciones implementadas en otros países y enfocadas a la prevención de los atropellos, las que podrían funcionar bien en Perú. De manera consistente, la implementación de intervenciones tales como el calmar el tráfico en áreas específicas a través de reductores de velocidad ("rompemuelles", minirotondas ("óvalos", mejor alumbramiento, calles unidireccionales, desvíos y bloqueos de las calles, tiene una fuerte evidencia en reducir las lesiones y fatalidades en los peatones.

    2013-07-01

    Full Text Available Vitamin D deficiency, as well as cardiovascular diseases (CVD and related risk factors are highly prevalent worldwide and frequently co-occur. Vitamin D has long been known to be an essential part of bone metabolism, although recent evidence suggests that vitamin D plays a key role in the pathophysiology of other diseases, including CVD, as well. In this review, we aim to summarize the most recent data on the involvement of vitamin D deficiency in the development of major cardiovascular risk factors: hypertension, obesity and dyslipidemia, type 2 diabetes, chronic kidney disease and endothelial dysfunction. In addition, we outline the most recent observational, as well as interventional data on the influence of vitamin D on CVD. Since it is still an unresolved issue whether vitamin D deficiency is causally involved in the pathogenesis of CVD, data from randomized controlled trials (RCTs designed to assess the impact of vitamin D supplementation on cardiovascular outcomes are awaited with anticipation. At present, we can only conclude that vitamin D deficiency is an independent cardiovascular risk factor, but whether vitamin D supplementation can significantly improve cardiovascular outcomes is still largely unknown.

    The thyroid hormone deficiency on cardiovascular function can be characterized with decreased myocardial contractility and increased peripheral vascular resistance as well as with the changes in lipid metabolism. 42 patients with cardiovascular disease (mean age 65 +/- 13 yr, 16 males) were investigated if iodine insufficiency can play a role as a risk factor for the cardiovascular diseases. The patients were divided in 5 subgroups on the ground of the presence of hypertension, congestive heart failure, cardiomyopathy, coronary disfunction and arrhythmia. Urine iodine concentration (5.29 +/- 4.52 micrograms/dl) was detected with Sandell-Kolthoff colorimetric reaction. The most decreased urine iodine concentration was detected in the subgroups with arrhythmia and congestive heart failure (4.7 +/- 4.94 micrograms/dl and 4.9 +/- 4.81 micrograms/dl, respectively). An elevated TSH level was found by 3 patients (5.3 +/- 1.4 mlU/l). An elevation in lipid metabolism (cholesterol, triglyceride) associated with all subgroups without arrhythmia. In conclusion, the occurrence of iodine deficiency in cardiovascular disease is frequent. Iodine supplementation might prevent the worsing effect of iodine deficiency on cardiovascular disease.

  7. Cardiovascular benefits of bariatric surgery.

    Lee, Glenn K; Cha, Yong-Mei

    2016-04-01

    The prevalence of obesity is increasing in the United States and worldwide, bringing with it an excess of morbidity and premature death. Obesity is strongly associated with both traditional cardiovascular risk factors as well as direct effects on hemodynamics and cardiovascular structure and function. In fact, cardiovascular disease is one of the major causes of morbidity and mortality in obese patients. Often, lifestyle and pharmacological weight-loss interventions are of limited efficacy in severely obese patients. Bariatric surgery has been shown to be a feasible option to achieve substantial and sustained weight loss in this group of patients. It is a safe procedure with low in-hospital and 30-day mortality rates even in groups that are considered higher risk for surgery (e.g., the elderly), especially if performed in high-volume centers. There is observational evidence that bariatric surgery in severely obese patients is associated with both a reduction of traditional cardiovascular risk factors as well as improvement in cardiac structure and function. Marked decreases in the levels of inflammatory and prothrombotic markers, as well as markers of subclinical atherosclerosis and endothelial dysfunction, are seen after bariatric surgery. This article summarizes the existing evidence regarding the cardiovascular benefits in patients following bariatric surgery.

  8. Cardiovascular effect is independent of hemolytic toxicity of tentacle-only extract from the jellyfish Cyanea capillata.

    Directory of Open Access Journals (Sweden)

    Xiao Liang

    Full Text Available Our previous studies have confirmed that the crude tentacle-only extract (cTOE from the jellyfish Cyanea capillata (Cyaneidae exhibits hemolytic and cardiovascular toxicities simultaneously. So, it is quite difficult to discern the underlying active component responsible for heart injury caused by cTOE. The inactivation of the hemolytic toxicity from cTOE accompanied with a removal of plenty of precipitates would facilitate the separation of cardiovascular component and the investigation of its cardiovascular injury mechanism. In our research, after the treatment of one-step alkaline denaturation followed by twice dialysis, the protein concentration of the treated tentacle-only extract (tTOE was about 1/3 of cTOE, and SDS-PAGE showed smaller numbers and lower density of protein bands in tTOE. The hemolytic toxicity of tTOE was completely lost while its cardiovascular toxicity was well retained. The observations of cardiac function, histopathology and ultrastructural pathology all support tTOE with significant cardiovascular toxicity. Blood gas indexes and electrolytes changed far less by tTOE than those by cTOE, though still with significant difference from normal. In summary, the cardiovascular toxicity of cTOE can exist independently of the hemolytic toxicity and tTOE can be employed as a better venom sample for further purification and mechanism research on the jellyfish cardiovascular toxic proteins.

    Vanichakarn, P; Hwa, J; Stitham, J

    2014-01-01

    Recent changes to the clinical management guidelines for hypertension and hyperlipidemia have placed emphasis on prevention through the pharmacological control and reduction of cardiovascular risk factors. In conjunction with proper diet and lifestyle changes, such risk factor control necessitates the use of safe and effective pharmacotherapy. However, many patients fail to reach or maintain therapeutic goals due to inadequacy and/or variability in response to antihypertensive and lipid-lowering medications. Thus, given the contribution of both hypertension and hyperlipidemia in the development and progression of cardiovascular disease, a personalized approach to pharmacotherapy, as well as disease prevention, seems particularly prudent. With the advancement of cardiovascular pharmacogenetics, the aim is to identify genetic biomarkers of drug-response and disease-susceptibility in order to make informed and individualized decisions, improving patient care through proper drug selection and dosing.

  11.  Cinacalcet therapy and cardiovascular risk in hemodialysis patients

    Full Text Available  Patients with end-stage kidney disease are at high cardiovascular risk due to accelerated atherosclerosis development. Important factors that accelerate the development of atherosclerosis in this group are calcium-phosphorus disturbances causing vascular calcification. Therefore, slowing the development and progression of vascular calcification is a novel therapeutic target in the treatment of calcium and phosphorus disturbances associated with chronic kidney disease. It seems that cinacalcet, a calcimimetic of the second generation, used in patients with refractory secondary hyperparathyroidism can slow the progression of vascular calcification and potentially reduce the cardiovascular risk. This paper reviews the current literature on the pathogenesis of vascular calcification and the potential impact of cinacalcet to reduce cardiovascular risk in patients with end-stage kidney disease.

    2014-01-01

    Full Text Available The current search for new markers of cardiovascular diseases (CVDs is explained by the high morbidity and mortality still observed in developed and developing countries due to cardiovascular events. Recently, microRNAs (miRNAs or miRs have emerged as potential new biomarkers and are small sequences of RNAs that regulate gene expression at posttranscriptional level by inhibiting translation or inducing degradation of the target mRNAs. Circulating miRNAs are involved in the regulation of signaling pathways associated to aging and can be used as novel diagnostic markers for acute and chronic diseases such as cardiovascular pathologies. This review summarizes the biogenesis, maturation, and stability of miRNAs and their use as potential biomarkers for coronary artery disease (CAD, myocardial infarction (MI, and heart failure (HF.

    2014-01-01

    Hexarelin, a synthetic growth hormone-releasing peptide, can bind to and activate the growth hormone secretagogue receptor (GHSR) in the brain similar to its natural analog ghrelin. However, the peripheral distribution of GHSR in the heart and blood vessels suggests that hexarelin might have direct cardiovascular actions beyond growth hormone release and neuroendocrine effects. Furthermore, the non-GHSR CD36 had been demonstrated to be a specific cardiac receptor for hexarelin and to mediate its cardioprotective effects. When compared with ghrelin, hexarelin is chemically more stable and functionally more potent. Therefore, it may be a promising therapeutic agent for some car-diovascular conditions. In this concise review, we discuss the current evidence for the cardiovascular action of hexarelin.

    Mondy, Kristin; Tebas, Pablo

    2007-01-01

    The use of highly active antiretroviral therapy (HAART) has resulted in sustained reductions in mortality from HIV infection. In recent years, HAART has also been associated with metabolic complications that may increase patients' cardiovascular disease risk. Recent studies have begun to support a more complex interaction between HAART, HIV infection itself, and other traditional social and immunologic factors that may predispose patients to premature cardiovascular disease. Substantial progress has been made in the development of newer antiretroviral therapies that have a better metabolic profile with respect to dyslipidemia, hyperglycemia, and lipodystrophy. Optimal selection of metabolically neutral antiretroviral therapies, together with aggressive management of other modifiable coronary risk factors, may improve cardiovascular disease risk in the long term.

  16. Social factors and cardiovascular morbidity.

    2017-03-01

    Recent progress in population health at aggregate level, measured by life expectancy, has been accompanied by lack of progress in reducing the difference in health prospects between groups defined by social status. Cardiovascular disease is an important contributor to this undesirable situation. The stepwise gradient of higher risk with lower status is accounted for partly by social gradients in health behaviors. The psychosocial hypothesis provides a stronger explanation, based on social patterning of living and working environments and psychological assets that individuals develop during childhood. Three decades of research based on Whitehall II and other cohort studies provide evidence for psychosocial pathways leading to cardiovascular morbidity and mortality. Job stress is a useful paradigm because exposure is long term and depends on occupational status. Studies of social-biological translation implicate autonomic and neuroendocrine function among the biological systems that mediate between chronic adverse psychosocial exposures and increased cardiometabolic risk and cardiovascular disease incidence.

    Toxocariasis is a parasitic infection produced by helminths that cannot reach their adult stage in humans. For their etiological species (Toxocara canis and Toxocara cati), man is a paratenic host. Infection by such helminths can produce a variety of clinical manifestations, such as: visceral larvae migrans syndrome, ocular larvae migrans syndrome and covert toxocariasis. In the visceral larvae migrans syndrome, the organs that are mainly involved include liver, lungs, skin, nervous system, muscles, kidneys and the heart. Regarding the latter, the importance of cardiovascular manifestations in toxocariasis, as well as its clinical relevance, has increasingly begun to be recognized. The current article is based on a systematic information search, focused mainly on the clinical and pathological aspects of cardiovascular manifestations in toxocariasis, including its pathophysiology, laboratory findings, diagnosis and therapeutical options, with the objective of highlighting its importance as a zoonosis and its relevance to the fields of cardiovascular medicine in adults and children.

    2012-02-01

    We sought to prospectively study all injuries in children and adolescents up to 16 years of age presenting to a regional Emergency Department (ED), to ascertain detailed injury patterns and to use this data to recommend injury prevention priorities. Electronic injury surveillance was prospectively collected over a 10 year period (1997-2007) in a hospital with a paediatric catchment population of 75,000 in a region with pockets of high social deprivation. All fatalities were obtained from data provided by the Central Statistics Office (CSO). Over a 10 year period, there were 31 fatalities, 5,408 admissions and 40,817 new attendances due to injury. Males outnumbered females in a 3:2 ratio. Of all injuries 24,317 (60%) occurred at home. Peak injury presentation time was in the evening between 18:00 and 20:00. Minor injuries (bruises, minor head injuries, lacerations and sprains) accounted for 32,456 (80%) of total. Fractures resulting from high falls (n=1,194) tended to result from bunk beds, staircases, horses, walls and playground equipment. Burns (n=630) involved hot liquids (tea, coffee), hot bath water, hot cooking oil and hot cooking plates. Pedestrian injuries (n=251) were predominantly \\'dart outs\\' in urban areas. Car passenger injuries (n=869) showed low rates of documented car restraint use. Poisonings (n= 1,153) were predominantly medicinal products. Cyclist injuries (n=477) indicated low documented use of appropriate helmet wear. Prevention priorities should focus on home injuries, hot liquid burn and scald injuries and high falls from walls, beds and playground equipment. To prevent road-related injuries and deaths, further legislation, urban planning and greater police enforcement is required.

  19. Vitamin D and cardiovascular disease: is the evidence solid?

    2013-12-01

    Vitamin D deficiency, prevalent in 30-50% of adults in developed countries, is largely due to inadequate cutaneous production that results from decreased exposure to sunlight, and to a lesser degree from low dietary intake of vitamin D. Serum levels of 25-hydroxyvitamin D (25-OH D) vitamin D deficiency and levels >30 ng/mL are considered optimal. While the endocrine functions of vitamin D related to bone metabolism and mineral ion homoeostasis have been extensively studied, robust epidemiological evidence also suggests a close association between vitamin D deficiency and cardiovascular morbidity and mortality. Experimental studies have demonstrated novel actions of vitamin D metabolites on cardiomyocytes, and endothelial and vascular smooth muscle cells. Low 25-OH D levels are associated with left ventricular hypertrophy, vascular dysfunction, and renin-angiotensin system activation. Despite a large body of experimental, cross-sectional, and prospective evidence implicating vitamin D deficiency in the pathogenesis of cardiovascular disease, a causal relationship remains to be established. Moreover, the cardiovascular benefits of normalizing 25-OH D levels in those without renal disease or hyperparathyroidism have not been established, and questions of an epiphenomenon where vitamin D status merely reflects a classic risk burden have been raised. Randomized trials of vitamin D replacement employing cardiovascular endpoints will provide much needed evidence for determining its role in cardiovascular protection.

    Full Text Available Abstract Background Consumption of chocolate has been often hypothesized to reduce the risk of cardiovascular disease (CVD due to chocolate's high levels of stearic acid and antioxidant flavonoids. However, debate still lingers regarding the true long term beneficial cardiovascular effects of chocolate overall. Methods We reviewed English-language MEDLINE publications from 1966 through January 2005 for experimental, observational, and clinical studies of relations between cocoa, cacao, chocolate, stearic acid, flavonoids (including flavonols, flavanols, catechins, epicatechins, and procynadins and the risk of cardiovascular disease (coronary heart disease (CHD, stroke. A total of 136 publications were selected based on relevance, and quality of design and methods. An updated meta-analysis of flavonoid intake and CHD mortality was also conducted. Results The body of short-term randomized feeding trials suggests cocoa and chocolate may exert beneficial effects on cardiovascular risk via effects on lowering blood pressure, anti-inflammation, anti-platelet function, higher HDL, decreased LDL oxidation. Additionally, a large body of trials of stearic acid suggests it is indeed cholesterol-neutral. However, epidemiologic studies of serum and dietary stearic acid are inconclusive due to many methodologic limitations. Meanwhile, the large body of prospective studies of flavonoids suggests the flavonoid content of chocolate may reduce risk of cardiovascular mortality. Our updated meta-analysis indicates that intake of flavonoids may lower risk of CHD mortality, RR = 0.81 (95% CI: 0.71–0.92 comparing highest and lowest tertiles. Conclusion Multiple lines of evidence from laboratory experiments and randomized trials suggest stearic acid may be neutral, while flavonoids are likely protective against CHD mortality. The highest priority now is to conduct larger randomized trials to definitively investigate the impact of chocolate consumption on long

    Endothelium has many important functions including the control of blood-tissue permeability and vascular tonus, regulation of vascular surface properties for homeostasis and inflammation. Nitric oxide is the chief molecule in regulation of endothelial functions. Nitric oxide deficiency, which is also known as endothelial dysfunction, is the first step for the occurrence of many disease states in cardiovascular system including heart failure, hypertension, dyslipidemia, insulin resistance, diabetes mellitus, hyperhomocysteinemia and smoking. This review deals with the importance of nitric oxide for cardiovascular system. It also includes the latest improvements in the diagnosis and treatment of endothelial dysfunction.

Even more, the concept of coronary disease as an inflammatory disease has developed new pathways for investigating the ischaemic cardiac. Recent investigations suggest that the use of inflammatory markers may help for early detecting patients who present high risk of cardiovascular strokes appearance. Also, epidemiological essays have revealed that periodontitis is a risk factor for cardiovascular disease to develop. Periodontitis is a source of bacterias or their wastes, and provoke a hyperinflammatory response on the hostage, liberating cytokines for long periods. Due to chronicity of both cardiovascular and periodontal disease, they may have some similar ethilogycal ways.

    Full Text Available Purpose Taekwondo, as the most popular martial art among Iranian sportsmen, might lead to injury for the athletes of this sport during competitions. We decided to report the incidence rate of injuries sustained by the athletes of this sport during national competitions. Methods All competitions of Iran national championship taekwondo league in 2006-2007 with 204 athletes were observed prospectively to detect the occurrence of injuries. The severity of injuries was classified into four groups (mild, moderate, severe, and critical according to the involvement of medical care team in the contest, ability of the athletes to resume and duration of probable absence of injured athletes from future competitions and training sessions. Athlete-Exposure (A-E was defined as the number of competitions multiplied by two. On this base, the rate of injury incidence per 1000 A-Es, the rate of injuries per time unit and the rate of injury occurred for each 100 athletes were considered as the major outcomes of this study. Results Of totally 1,338 A-Es, 93 injuries were recorded during the competitions. The rate of injury incidence was found to be 69.5 injuries per 1000 A-Es and the rate of injuries per minute of competitions was 0.023 which corresponded to 23.3 injuries per 1000 minutes of competitions. 45.6 injuries were occurred for each 100 athletes during the course of competitions. The most frequent injuries were mild (68.8% and critical injuries (24.7%, followed by moderate and severe injuries; 4.3% and 2.1%, respectively. Conclusion The rate of injury we found was lower than that of western countries. In spite of finding the lower limbs as the most frequent place of injuries in other studies, we found the upper limbs as the most predisposed place of injuries which might be due to difference in the method of combat of Iranian athletes with other athletes.

    2016-07-01

    Full Text Available BACKGROUND The spleen is an important organ in the body’s immune system. It is the most frequently injured organ in blunt abdominal trauma. 1 Over the past several decades, diagnosis and management of splenic trauma has been evolved. The conservative, operative approach has been challenged by several reports of successful non-operative management aided by the power of modern diagnostic imaging. The aim of our prospective study was to compare non-operative management with surgery for cases of splenic injury. METHODS We conducted a prospective study of patients admitted with blunt splenic injury to our regional hospital over a three-year period (2012-2015. Haemodynamic status upon admission, FAST examination, computed tomography 2 grade of splenic tear, presence and severity of associated injuries have been taken into account to determine the treatment of choice. Therapeutic options were classified into non-operative and splenectomy. RESULTS Over a 3-year period, 24 patients were admitted with blunt splenic injury. Sixteen patients were managed operatively and eight patients non-operatively. 3,4 Non-operative management failed in one patient due to continued bleeding. The majority of grades I, II, and III splenic injuries were managed non-operatively and grades IV and V were managed operatively. Blood transfusion requirement was significantly higher among the operative group, but the operative group had a significantly longer hospital stay. Among those managed non-operatively (median age 24.5 years, a number of patients were followed up with CT scans with significant radiation exposure and unknown longterm consequences. CONCLUSION In our experience, NOM is the treatment of choice for grade I, II and III blunt splenic injuries. Splenectomy was the chosen technique in patients who met exclusion criteria for NOM, as well as for patients with grade IV and V injury.

    2013-01-01

    Full Text Available Although selenium metabolism is intricately linked to cardiovascular biology and function, and deficiency of selenium is associated with cardiac pathology, utilization of selenium in the prevention and treatment of cardiovascular disease remains an elusive goal. From a reductionist standpoint, the major function of selenium in vivo is antioxidant defense via its incorporation as selenocysteine into enzyme families such as glutathione peroxidases and thioredoxin reductases. In addition, selenium compounds are heterogeneous and have complex metabolic fates resulting in effects that are not entirely dependent on selenoprotein expression. This complex biology of selenium in vivo may underlie the fact that beneficial effects of selenium supplementation demonstrated in preclinical studies using models of oxidant stress-induced cardiovascular dysfunction, such as ischemia-reperfusion injury and myocardial infarction, have not been consistently observed in clinical trials. In fact, recent studies have yielded data that suggest that unselective supplementation of selenium may, indeed, be harmful. Interesting biologic actions of selenium are its simultaneous effects on redox balance and methylation status, a combination that may influence gene expression. These combined actions may explain some of the biphasic effects seen with low and high doses of selenium, the potentially harmful effects seen in normal individuals, and the beneficial effects noted in preclinical studies of disease. Given the complexity of selenium biology, systems biology approaches may be necessary to reach the goal of optimization of selenium status to promote health and prevent disease.

    The bioactive lipid mediator lysophosphatidic acid (LPA) exerts a range of effects on the cardiovasculature that suggest a role in a variety of critical cardiovascular functions and clinically important cardiovascular diseases. LPA is an activator of platelets from a majority of human donors identifying a possible role as a regulator of acute thrombosis and platelet function in atherogenesis and vascular injury responses. Of particular interest in this context, LPA is an effective phenotypic modulator of vascular smooth muscle cells promoting the de-differentiation, proliferation and migration of these cells that are required for the development of intimal hyperplasia. Exogenous administration of LPA results in acute and systemic changes in blood pressure in different animal species, suggesting a role for LPA in both normal blood pressure regulation and hypertension. Advances in our understanding of the molecular machinery responsible for the synthesis, actions and inactivation of LPA now promise to provide the tools required to define the role of LPA in cardiovascular physiology and disease. In this review we discuss aspects of LPA signaling in the cardiovasculature focusing on recent advances and attempting to highlight presently unresolved issues and promising avenues for further investigation.

    Over twenty five years ago epidemiological studies revealed that there was a relationship between patterns of early growth and subsequent risk of diseases such as type 2 diabetes, cardiovascular disease and the metabolic syndrome. Studies of identical twins, individuals who were in utero during periods of famine, discordant siblings and animal models have provided strong evidence that the early environment plays an important role in mediating these relationships. Early nutrition is one such important environmental factor. The concept of early life programming is therefore widely accepted and the underlying mechanisms starting to emerge. These include: (1) Permanent structural changes in an organ due to exposure to suboptimal levels of essential hormones or nutrients during a critical period of development leading to permanent changes in tissue function (2) Persistent epigenetic changes such as DNA methylation and histone modifications and miRNAs leading to changes in gene expression. (3) Permanent effects on regulation of cellular ageing through increases in oxidative stress and mitochondrial dysfunction leading to DNA damage and telomere shortening. Further understanding of these processes will enable the development of preventative and intervention strategies to combat the burden of common diseases such as type 2 diabetes and cardiovascular disease.

  12. Lycopene Deficiency in Ageing and Cardiovascular Disease.

    Petyaev, Ivan M

    2016-01-01

    Lycopene is a hydrocarbon phytochemical belonging to the tetraterpene carotenoid family and is found in red fruit and vegetables. Eleven conjugated double bonds predetermine the antioxidant properties of lycopene and its ability to scavenge lipid peroxyl radicals, reactive oxygen species, and nitric oxide. Lycopene has a low bioavailability rate and appears in the blood circulation incorporated into chylomicrons and other apo-B containing lipoproteins. The recent body of evidence suggests that plasma concentration of lycopene is not only a function of intestinal absorption rate but also lycopene breakdown via enzymatic and oxidative pathways in blood and tissues. Oxidative stress and the accumulation of reactive oxygen species and nitric oxide may represent a major cause of lycopene depletion in ageing, cardiovascular disease, and type 2 diabetes mellitus. It has been shown recently that low carotenoid levels, and especially decreased serum lycopene levels, are strongly predictive of all-cause mortality and poor outcomes of cardiovascular disease. However, there is a poor statistical association between dietary and serum lycopene levels which occurs due to limited bioavailability of lycopene from dietary sources. Hence, it is very unlikely that nutritional intervention alone could be instrumental in the correction of lycopene and carotenoid deficiency. Therefore, new nutraceutical formulations of carotenoids with enhanced bioavailability are urgently needed.

    Cardiovascular disease is the number one cause of death worldwide. It is broadly defined to include anything which adversely affects the heart or blood vessels. One-third of Americans have one or more forms of it. By one estimate, average human life expectancy would increase by seven years if it were eliminated. The mainstream medical model seeks mostly to "manage" cardiovascular disease with pharmaceuticals or to surgically bypass or reopen blocked vessels via angioplasty. These methods have proven highly useful and saved countless lives. Yet drug therapy may be costly and ongoing, and it carries the risk of side effects while often doing little or nothing to improve underlying health concerns. Similarly, angioplasty or surgery are invasive methods which entail risk. Laser therapy1 regenerates tissue, stimulates biological function, reduces inflammation and alleviates pain. Its efficacy and safety have been increasingly well documented in cardiovascular disease of many kinds. In this article we will explore the effects of laser therapy in angina, atherosclerosis, coronary artery disease, hypertension, hyperlipidemia, myocardial infarction, stroke and other conditions. The clinical application of various methods of laser therapy, including laserpuncture and transcutaneous, supravascular and intravenous irradiation of blood will be discussed. Implementing laser therapy in the treatment of cardiovascular disease offers the possibility of increasing the health and wellbeing of patients while reducing the costs and enhancing safety of medical care.

    Full Text Available Cardiovascular diseases are the first leading cause of death and morbidity in developed countries. The use of animal models have contributed to increase our knowledge, providing new approaches focused to improve the diagnostic and the treatment of these pathologies. Several models have been developed to address cardiovascular complications, including atherothrombotic and cardiac diseases, and the same pathology have been successfully recreated in different species, including small and big animal models of disease. However, genetic and environmental factors play a significant role in cardiovascular pathophysiology, making difficult to match a particular disease, with a single experimental model. Therefore, no exclusive method perfectly recreates the human complication, and depending on the model, additional considerations of cost, infrastructure, and the requirement for specialized personnel, should also have in mind. Considering all these facts, and depending on the budgets available, models should be selected that best reproduce the disease being investigated. Here we will describe models of atherothrombotic diseases, including expanding and occlusive animal models, as well as models of heart failure. Given the wide range of models available, today it is possible to devise the best strategy, which may help us to find more efficient and reliable solutions against human cardiovascular diseases.

    Genome-editing tools, which include zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) systems, have emerged as an invaluable technology to achieve somatic and germline genomic manipulation in cells and model organisms for multiple applications, including the creation of knockout alleles, introducing desired mutations into genomic DNA, and inserting novel transgenes. Genome editing is being rapidly adopted into all fields of biomedical research, including the cardiovascular field, where it has facilitated a greater understanding of lipid metabolism, electrophysiology, cardiomyopathies, and other cardiovascular disorders, has helped to create a wider variety of cellular and animal models, and has opened the door to a new class of therapies. In this Review, we discuss the applications of genome-editing technology throughout cardiovascular disease research and the prospect of in vivo genome-editing therapies in the future. We also describe some of the existing limitations of genome-editing tools that will need to be addressed if cardiovascular genome editing is to achieve its full scientific and therapeutic potential.

    Full Text Available miRNAs are a novel class of non-coding RNAs which found their way into the clinic due to their fundamental roles in cellular processes such as differentiation, proliferation and apoptosis. Recently, miRNAs have been known as micromodulators in cellular communications being involved in cell signaling and microenvironment remodeling. In this review, we will focus on the role of miRNAs in cardiovascular diseases (CVDs and their reliability as diagnostic and therapeutic biomarkers in these conditions. Cardiovascular diseases comprise a variety of blood vessels and heart disorders with a high rate of morbidity and mortality worldwide. This necessitates introduction of novel molecular biomarkers for early detection, prevention or treatment of these diseases. miRNAs, due to their stability, tissue-specific expression pattern and secretion to the corresponding body fluids, are attractive targets for cardiovascular-associated therapeutics. Explaining the challenges ahead of miRNA-based therapies, we will discuss the exosomes as delivery packages for miRNA drugs and promising novel strategies for the future of miRNA-based therapeutics. These approaches provide insights to the future of personalized medicine for the treatment of cardiovascular diseases.

    Cardiovascular (CV) diseases are becoming increasingly frequent and associated with a high incidence of CV events, disability and death. It is known that there is a relationship between CV burden and systemic autoimmune diseases (SADs) that is mainly due to inflammation and autoimmunity, but the other mechanisms underlying the high CV risk of SAD patients have not yet been fully clarified. The aim of this review article is to discuss some of the specific factors associated with the accelerated atherosclerosis (ATS) characterising SADs (female sex, the microcirculation and the endothelium) in order to highlight the importance of an early diagnosis and the prompt implementation of preventive measures, as well as the possible role of new therapeutic strategies such as vaccine immunomodulation. Finally, as the natural history of ATS begins with endothelial injury (a potentially reversible process that is influenced by various factors) and microvascular damage plays a central role in the etiopathogenesis of SADs, it underlines the crucial need for the development of reliable means of detecting sub-clinical abnormalities in the microcirculation, particularly coronary microcirculation dysfunction.

    2012-02-01

    Recent reports from needle exchange programmes and other public health initiatives have suggested growing use of anabolic steroids (AS) in the UK and other countries. Data indicate that AS use is not confined to body-builders or high-level sportsmen. Use has spread to professionals working in emergency services, casual fitness enthusiasts and subelite sportsmen and women. Although the precise health consequences of AS use is largely undefined, AS use represents a growing public health concern. Data regarding the consequences of AS use on cardiovascular health are limited to case studies and a modest number of small cohort studies. Numerous case studies have linked AS use with a variety of cardiovascular disease (CVD) events or endpoints, including myocardial infarction, stroke and death. Large-scale epidemiological studies to support these links are absent. Consequently, the impact of AS use upon known CVD risk factors has been studied in relatively small, case-series studies. Data relating AS use to elevated blood pressure, altered lipid profiles and ECG abnormalities have been reported, but are often limited in scope, and other studies have often produced equivocal outcomes. The use of AS has been linked to the appearance of concentric left ventricular hypertrophy as well as endothelial dysfunction but the data again remains controversial. The mechanisms responsible for the negative effect of AS on cardiovascular health are poorly understood, especially in humans. Possibilities include direct effects on myocytes and endothelial cells, reduced intracellular Ca2+ levels, increased release of apoptogenic factors, as well as increased collagen crosslinks between myocytes. New data relating AS use to cardiovascular health risks are emerging, as novel technologies are developed (especially in non-invasive imaging) that can assess physiological structure and function. Continued efforts to fully document the cardiovascular health consequences of AS use is important to

    Full Text Available As men grow older, testosterone (T levels decline and the significance of this change is debated. The evidence supporting a causal role for lower circulating T, or its metabolites dihydrotestosterone (DHT and estradiol, in the genesis of atherosclerosis and cardiovascular disease (CVD in men is limited. Observational studies associate low baseline T levels with carotid atherosclerosis, aortic and peripheral vascular disease, and with the incidence of cardiovascular events and mortality. Studies using mass spectrometry suggest that when total T is assayed optimally, calculation of free T might not necessarily improve risk stratification. There is limited evidence to support an association of estradiol with CVD. Interventional studies of T therapy in men with coronary artery disease have shown beneficial effects on exercise-induced myocardial ischemia. However, placebo-controlled, randomized clinical trials (RCTs of T therapy in men with the prespecified outcomes of cardiovascular events or deaths are lacking. Meta-analyses of randomized controlled trials of T published up to 2010 found no increase in cardiovascular events, mortality, or prostate cancer with therapy. Recently, in a trial of older men with mobility limitations, men randomized to receive a substantial dose of T reported cardiovascular adverse effects. This phenomenon was not reported from a comparable trial where men received a more conservative dose of T, suggesting a prudent approach should be adopted when considering therapy in frail older men with existing CVD. Adequately powered RCTs of T in middle-aged and older men are needed to clarify whether or not hormonal intervention would reduce the incidence of CVD.

    Revue productions are a combination of dancing and singing, musical and spoken sequences, and acrobatics, performed with or without a story line, and characterized by a versatility of dance styles and a high number of performances (over 250 in a 10-month season). The aim of this quantitative single cohort study is to evaluate work-related traumatic injuries in this dance genre. Data were obtained from work accident reports of the German Social Accident Insurance Institution for the public sector in Berlin (UKB) involving 440 revue dancers (183 males and 257 females). Analysis was conducted with Excel 2007 and PASW Statistics 18. One out of three female dancers and one out of two male dancers sustained an acute injury in the course of a theatrical season (0.22 injuries per 1,000 hours). The incidence rate was 0.44 for males and 0.31 for females, with the lower extremity as the most commonly injured body region, followed by the spine. Of all occupational accidents, 75.1% happened on stage, with 69% during performances. The dance partner and dance floor were the most common exogenous factors resulting in a traumatic injury. Of all traumatic injuries, 81.7% occurred in the first 3 hours after starting work. Gender specific differences could be observed. Due to the limited availability of comparable studies of other forms of professional dance, in this study revue dance is largely considered as an independent genre.

    Full Text Available A review was conducted to present current views and effectiveness of prevention and rehabilitation methods of hamstring injuries. Methods: a review searching on the electronic data bases, including Proquest, Medline, Sport Discus, Cinahl plus, Health source Nursing / Academic edition, Academic search complete, Pub med and Scholar Google. Only randomized control studies (RCT'S were included which contained the intervention and control groups concerning either the prevention or rehabilitation of hamstrings. Results: fourteen randomized control studies were included. Twelve concerned the prevention and two the rehabilitation of hamstring injuries. From the analysis of the articles concerning prevention we concluded that stretching, especially static and warm up program named "The 11" did not show any benefits in preventing hamstring injuries whilst strength training exercises with eccentric contraction (Nordic exercises and warm-up program "The 11+" containing eccentric exercises of hamstring showed significant differences regarding the prevention. It is postulated that the effectiveness of this may be due to the fact that the researchers had targeted the progressive increase in the intensity and frequency of eccentric exercises. Conclusions: eccentric exercises seem (based on the findings included in this study to have an important role in the prevention and strengthening immediately after hamstring injury and also significantly role on reducing the risk of reinjury. A rehabilitation program that includes mainly stretching exercises with eccentric loading of hamstrings muscles and secondly an exercise program which includes core stability and progressive agility exercises were found to be the most effective for recovery after hamstrings injury.

  12. Retrospective cohort analysis of chest injury characteristics and concurrent injuries in patients admitted to hospital in the Wenchuan and Lushan earthquakes in Sichuan, China.

    Full Text Available BACKGROUND: The aim of this study was to compare retrospectively the characteristics of chest injuries and frequencies of other, concurrent injuries in patients after earthquakes of different seismic intensity. METHODS: We compared the cause, type, and body location of chest injuries as well as the frequencies of other, concurrent injuries in patients admitted to our hospital after the Wenchuan and Lushan earthquakes in Sichuan, China. We explored possible relationships between seismic intensity and the causes and types of injuries, and we assessed the ability of the Injury Severity Score, New Injury Severity Score, and Chest Injury Index to predict respiratory failure in chest injury patients. RESULTS: The incidence of chest injuries was 9.9% in the stronger Wenchuan earthquake and 22.2% in the less intensive Lushan earthquake. The most frequent cause of chest injuries in both earthquakes was being accidentally struck. Injuries due to falls were less prevalent in the stronger Wenchuan earthquake, while injuries due to burial were more prevalent. The distribution of types of chest injury did not vary significantly between the two earthquakes, with rib fractures and pulmonary contusions the most frequent types. Spinal and head injuries concurrent with chest injuries were more prevalent in the less violent Lushan earthquake. All three trauma scoring systems showed poor ability to predict respiratory failure in patients with earthquake-related chest injuries. CONCLUSIONS: Previous studies may have underestimated the incidence of chest injury in violent earthquakes. The distributions of types of chest injury did not differ between these two earthquakes of different seismic intensity. Earthquake severity and interval between rescue and treatment may influence the prevalence and types of injuries that co-occur with the chest injury. Trauma evaluation scores on their own are inadequate predictors of respiratory failure in patients with earthquake

    This paper describes hospitalisations due to falls among people aged 65 years and over resident in the Eastern Region of Ireland. Of the 2,029 hospitalisations recorded for 2002, 78% were female and 68% were aged 75 years and over. Fractures accounted for 1,697 or 84% of cases with nearly half of them (841) sustained to the hip. Females were more likely to have a limb fracture whereas males were more likely to have a head injury. The total inpatient costs of the 2,029 hospitalisations were estimated at 10.6 million euros. Hip fractures were the costliest injuries as they accounted for 7.4 million euros (70%) of inpatient costs. There are also substantial additional costs implications for hip fractures as they constituted the majority (56%) of cases transferred to nursing\\/convalescent homes or long-stay health facilities. In keeping with an ageing population, the problem of injuries in older people is likely to increase over time and as falls are the dominant cause of those injuries, all acute and long-stay health facilities need to develop and implement fall prevention strategies for older people.

    The sport of triathlon offers athletes the chance to build and/or maintain cardiovascular fitness across 3 endurance disciplines. Swimming, biking, and running each have a host of overuse injuries that can occur as a result of overtraining. High running mileage, a history of previous injury, inadequate warm up or cool down, and an increase in the years of triathlon experience are a few of the factors that have been linked to triathlon overuse injuries. Early identification of overtraining symptoms and a corresponding reallocation of balance between each discipline, perhaps with an emphasis on increasing swimming, may help prevent many overuse injuries.

    Injuries and violence are one of the leading causes of mortality worldwide. A substantial portion of these injuries involve the maxillofacial region. Among the concomitant injuries, injuries to the head and cervical spine are amongst those that demand due consideration on account of their life threatening behaviour. Studies have shown that facial fractures have a strong association with traumatic brain injury. Knowledge of the types and mechanisms of traumatic brain injury is crucial for their treatment. Many a times, facial fractures tend to distract our attention from more severe and often life threatening injuries. Early diagnosis of these intracranial haemorrhage leads to prompt treatment which is essential to improve the outcome of these patients. An oral and maxillofacial surgeon should be able to suspect and diagnose head injury and also provide adequate initial management. PMID:26894193

    Nonalcoholic fatty liver disease (NAFLD) encompasses a range of liver histology severity and outcomes in the absence of chronic alcohol use. The mildest form is simple steatosis in which triglycerides accumulate within hepatocytes. A more advanced form of NAFLD, nonalcoholic steatohepatitis, includes inflammation and liver cell injury, progressive to cryptogenic cirrhosis. NAFLD has become the most common cause of chronic liver disease in children and adolescents. The recent rise in the prevalence rates of overweight and obesity likely explains the NAFLD epidemic worldwide. NAFLD is strongly associated with abdominal obesity, type 2 diabetes, and dyslipidemia, and most patients have evidence of insulin resistance. Thus, NAFLD shares many features of the metabolic syndrome (MetS), a highly atherogenic condition, and this has stimulated interest in the possible role of NAFLD in the development of atherosclerosis. Accumulating evidence suggests that NAFLD is associated with a significantly greater overall mortality than in the general population, as well as with increased prevalence of cardiovascular disease (CVD), independently of classical atherosclerotic risk factors. Yet, several studies including the pediatric population have reported independent associations between NAFLD and impaired flow-mediated vasodilatation and increased carotid artery intimal medial thickness-two reliable markers of subclinical atherosclerosis-after adjusting for cardiovascular risk factors and MetS. Therefore, the rising prevalence of obesity-related MetS and NAFLD in childhood may lead to a parallel increase in adverse cardiovascular outcomes. In children, the cardiovascular system remains plastic and damage-reversible if early and appropriate interventions are established effectively. Therapeutic goals for NAFLD should address nutrition, physical activity, and avoidance of smoking to prevent not only end-stage liver disease but also CVD.

    The aim of this article is to analyze the vascular dysfunctions occurring after spinal cord injury (SCI). Vascular dysfunctions are common complications of SCI. Cardiovascular disturbances are the leading causes of morbidity and mortality in both acute and chronic stages of SCI. Neuroanatomy and physiology of autonomic nervous system, sympathetic and parasympathetic, is reviewed. SCI implies disruption of descendent pathways from central centers to spinal sympathetic neurons, originating in intermediolateral nuclei of T1-L2 cord segments. Loss of supraspinal control over sympathetic nervous system results in reduced overall sympathetic activity below the level of injury and unopposed parasympathetic outflow through intact vagal nerve. SCI associates significant vascular dysfunction. Spinal shock occurs during the acute phase following SCI and it is a transitory suspension of function and reflexes below the level of the injury. Neurogenic shock, part of spinal shock, consists of severe arterial hypotension and bradycardia. Autonomic dysreflexia appears during the chronic phase, after spinal shock resolution, and it is a life-threatening syndrome of massive imbalanced reflex sympathetic discharge occurring in patients with SCI above the splanchnic sympathetic outflow (T5-T6). Arterial hypotension with orthostatic hypotension occurs in both acute and chronic phases. The etiology is multifactorial. We described a few factors influencing the orthostatic hypotension occurrence in SCI: sympathetic nervous system dysfunction, low plasma catecholamine levels, rennin-angiotensin-aldosterone activity, peripheral alpha-adrenoceptor hyperresponsiveness, impaired function of baroreceptors, hyponatremia and low plasmatic volume, cardiovascular deconditioning, morphologic changes in sympathetic neurons, plasticity within spinal circuits, and motor deficit leading to loss of skeletal muscle pumping activity.

The drugs examined were beta agonists [BA], ipratropium bromide IB, and inhaled steroids (ICS. End points were first hospitalizations for supraventricular tachycardia, myocardial infarction, heart failure or stroke. A nested case control analysis was employed comparing people with and without cardiovascular events. Cases and controls were matched for gender and age, and conditional logistic regression was used in multivariate analysis considering other respiratory drugs, respiratory diagnosis and visit frequency, non-respiratory, non-cardiac comorbidities, and receipt of drugs for cardiovascular disease. In univariate analyses, BA, IB and ICS were all associated with hospitalizations for cardiovascular disease, but in multivariate analyses ICS did not increase risk while both BA and IB did. There were interactions between respiratory and cardiac drugs receipt in that bronchodilator associated risks were higher in people not taking cardiac drugs; this was especially true for stroke. There were strong interactions with specific cardiac drugs; for example, both BA and IB substantially increased the risk of supraventricular tachycardia in patients not anti-arryhthmic agents, but not in the presence of such agents. We conclude that bronchodilator therapy for chronic obstructive diseases is associated with increased cardiovascular risk, especially in patients without previous cardiovascular diagnoses, and that this is unlikely due to the severity of the respiratory disease, since risk was not increased with ICS.Keywords: bronchodilator therapy, inhaled corticosteroids, nested case

  5. Transcapillary transport after thermal injury.

    The pathophysiology of the burn wound is characterized by an inflammatory reaction leading to rapid edema formation due to (1) dilatation of resistance vessels with increased effective transcapillary filtration pressure, (2) increased extravascular osmotic activity created in damaged tissue, and (3) increased microvascular permeability to macromolecules. In extensive burns increased microvascular permeability was found also in tissues remote from the thermal injury. These reactions are due to direct heat effect on the microvasculature and to chemical mediators of inflammation. Important is the increased biosynthesis of prostaglandins at the site of tissue injury which may partly explain vasodilatation, increased microvascular permeability and accumulation of polymorphonuclear leucocytes observed following thermal injury. The morphological interpretations of the changes in the functional ultrastructure of the blood-lymph barrier following thermal injury seem to be a remarkable and persistant increase in the numbers of vacuoles and many open endothelial intercellular junctions. Further less explored changes of the interstitial tissue after severe burn trauma seem to be of great importance.

    Full Text Available CONTEXT: Though the cardiovascular diseases are the leading cause of mortality in India, little is known about the human and economic loss attributed to the disease. The aim of this paper is to account the age and sex pattern of mortality, hospitalisation and the cost of hospitalisation for cardiovascular diseases in India. DATA AND METHODS: Data for the present study has been drawn from multiple sources; 52(nd and 60(th rounds of the National Sample Survey, Special Survey of Death, 2001-03 and the Sample Registration System 2004-2010. Under the changing demographics and constant assumptions of mortality, hospitalisation and cost of hospitalisation, we have estimated the deaths, hospitalisation and cost of hospitalisation for cardiovascular diseases in India during 2004 to 2021. Descriptive analyses and multivariate techniques were used to understand the socio-economic differentials in cost of hospitalisation for cardiovascular diseases in India. FINDINGS: In India, the cardiovascular diseases accounted for an estimated 1.4 million deaths in 2004 and it is likely to be 2.1 million in 2021. An estimated 6.7 million people were hospitalised for cardiovascular diseases in 2004, and projected to be 10.9 million by 2021. Unlike mortality, majority of the hospitalisation due to cardiovascular diseases will be in the prime working age group (25-59. The estimated cost of hospitalisation for cardiovascular diseases was 94/- billion rupees in 2004 and expected to be 152/- billion rupees by 2021, at 2004 prices. The cost of hospitalisation for cardiovascular diseases was significantly high in private health centres, high fertility states and among high socio-economic groups. CONCLUSION: The cardiovascular mortality and hospitalisation will be largely concentrated in the prime working age group and the cost of hospitalisation is expected to increase substantially in coming years. This calls for mobilising resources, increasing access to health insurance and

    American football is a high-energy contact sport that places players at risk for cervical spine injuries with potential neurological deficits. Advances in tackling and blocking techniques, rules of the game and medical care of the athlete have been made throughout the past few decades to minimize the risk of cervical injury and improve the management of injuries that do occur. Nonetheless, cervical spine injuries remain a serious concern in the game of American football. Injuries have a wide spectrum of severity. The relatively common 'stinger' is a neuropraxia of a cervical nerve root(s) or brachial plexus and represents a reversible peripheral nerve injury. Less common and more serious an injury, cervical cord neuropraxia is the clinical manifestation of neuropraxia of the cervical spinal cord due to hyperextension, hyperflexion or axial loading. Recent data on American football suggest that approximately 0.2 per 100,000 participants at the high school level and 2 per 100,000 participants at the collegiate level are diagnosed with cervical cord neuropraxia. Characterized by temporary pain, paraesthesias and/or motor weakness in more than one extremity, there is a rapid and complete resolution of symptoms and a normal physical examination within 10 minutes to 48 hours after the initial injury. Stenosis of the spinal canal, whether congenital or acquired, is thought to predispose the athlete to cervical cord neuropraxia. Although quite rare, catastrophic neurological injury is a devastating entity referring to permanent neurological injury or death. The mechanism is most often a forced hyperflexion injury, as occurs when 'spear tackling'. The mean incidence of catastrophic neurological injury over the past 30 years has been approximately 0.5 per 100,000 participants at high school level and 1.5 per 100,000 at the collegiate level. This incidence has decreased significantly when compared with the incidence in the early 1970s. This decrease in the incidence of

    Impalement bicycle handlebar trauma injuries are rare; however, on initial assessment, they have the potential of being underestimated. We reviewed our prospective trauma database of 3,894 patients for all bicycle injuries from January 2010 to May 2015. Isolated pedal bike injuries were reported in 2.6% (N = 101) of the patients who were admitted to the trauma service. Fifteen patients suffered direct handlebar trauma. Patients were grouped into blunt trauma (n = 12) and impalement trauma (n = 3). We examined gender, age, injury severity score (ISS), Glasgow Coma Scale score, use of protective devices, need for surgical intervention, need for intensive care (ICU), and hospital length of stay. Mean age was 9.6 years. All children with penetrating injuries were males. Mean ISS was less than 9 in both groups. None of the children were wearing bicycle helmets. Three patients who sustained blunt injuries required ICU care due to associated injuries. All of the children with impalement injuries required several surgical interventions. These injuries included a traumatic direct inguinal hernia, a medial groin and thigh laceration with resultant femoral hernia, and a lateral deep thigh laceration. Impalement bicycle handlebar injuries must be thoroughly evaluated, with a similar importance given to blunt injuries. A high index of suspicion must be maintained when examining children with handlebar impalement injuries, as they are at risk for missed or underestimation of their injuries.

    A common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. Gastric injury has been observed in patients who ingested alkali. Gastric outlet obstruction (GOO) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion. The traditional treatment for GOO related to ingestion of corrosive agents is surgery. Experience w...

    Sports injuries may be unique in childhood and adolescence due to the inherent weakness of the growing skeleton at specific sites, mainly the cartilaginous parts. Many injuries are predictable based on the known mechanism of injury encountered in certain sports. There are two distinct patterns of injury in sports; acute and chronic or overuse. Imaging plays an important role in the diagnosis and management of these entities. Radiologists should be familiar with the advantages and limitations of the various imaging modalities when evaluating the injured young athlete. The present review focuses on the radiological findings and appropriate imaging approach in injuries that are typically or most commonly encountered in the skeletally immature athletes.

    Cardiovascular complications are one of the major factors for early mortality in the present worldwide scenario and have become a major challenge in both developing and developed nations. It has thus become of immense importance to look for different therapeutic possibilities and treatments for the growing burden of cardiovascular diseases. Recent advancements in research have opened various means for better understanding of the complication and treatment of the disease. Adenosine receptors have become tool of choice in understanding the signaling mechanism which might lead to the cardiovascular complications. Adenosine A3 receptor is one of the important receptor which is extensively studied as a therapeutic target in cardiovascular disorder. Recent studies have shown that A3AR is involved in the amelioration of cardiovascular complications by altering the expression of A3R. This review focuses towards the therapeutic potential of A3AR involved in cardiovascular disease and it might help in better understanding of mechanism by which this receptor may prove useful in improving the complications arising due to various cardiovascular diseases. Understanding of A3AR signaling may also help to develop newer agonists and antagonists which might be prove helpful in the treatment of cardiovascular disorder.

    The oxidative stress plays an important role in the development of cardiovascular diseases (CVD). In CVD progression an aberrant redox regulation was observed. In this regulation levels of reactive oxygen species (ROS) play an important role in cellular signaling, where Nrf2 is the key regulator of redox homeostasis. Keap1-Nrf2-ARE system regulates a great set of detoxificant and antioxidant enzymes in cells after ROS and electrophiles exposure. In this review we focus on radical-generating systems in cardiovascular system as well as on Nrf2 as a target against oxidative stress and a key player of redox regulation in cardiovascular diseases. We also summarize the current knowledge about the role of Nrf2 in pathophysiology of several CVD (hypertension, cardiac hypertrophy, cardiomyopathies) as well as in cardioprotection against myocardial ischemia/ reperfusion injury.

    2011-01-01

    Full Text Available Midlife cardiovascular risk factors, including diabetes, hypertension, dyslipemia, and an unhealthy lifestyle, have been linked to subsequent incidence, delay of onset, and progression rate of Alzheimer disease and vascular dementia. Conversely, optimal treatment of cardiovascular risk factors prevents and slows down age-related cognitive disorders. The impact of antihypertensive therapy on cognitive outcome in patients with hypertension was assessed in large trials which demonstrated a reduction in progression of MRI white matter hyperintensities, in cognitive decline and in incidence of dementia. Large-scale database correlated statin use and reduction in the incidence of dementia, mainly in patients with documented atherosclerosis, but clinical trials failed to reach similar conclusions. Whether a multitargeted intervention would substantially improve protection, quality of life, and reduce medical cost expenditures in patients with lower risk profile has not been ascertained. This would require appropriately designed trials targeting large populations and focusing on cognitive decline as a primary outcome endpoint.

    Stereochemistry in drug molecules is rapidly becoming an important aspect in drug research, design, and development. Recently, individual stereoisomers of drug molecules with asymmetric centers such as fexofenadine, cetirizine, verapamil, fluoxetine, levalbutarol, and amphetamine, for example, have been separated and developed as individual drugs. These stereoisomers have different therapeutic activity, and each isomer has contributed differently with respect to its formulation's pharmacologic activity, side effects, and toxicity. The present overview discusses chirality among a select group of cardiovascular drugs, their stereochemical synthesis/preparation, isolation techniques using chiral chromatography, methods for confirmation of their enantiomeric purity, pharmacodynamics, and pharmacokinetics. Chirality has been visualized as an important factor in cardiovascular research. It is also becoming evident in other areas of therapeutics.

    The recently devised therapy for psoriasis and related skin diseases, consisting of long-wave ultraviolet light and oral 8-methoxypsoralen (PUVA), was investigated for its cardiovascular effects. In seventeen patients, long-wave ultraviolet light therapy in a treatment enclosure (mean duration, 19.3 minutes) resulted in ambient temperatures of 39.2 degrees C +/- 2.1 degrees C (SD) and skin temperatures of 38.2 degrees C +/- 1.4 degrees C. In upright subjects, heart rate rose 30.8% to 114.4 +/- 25.2 beats per minute (bpm). Intensive room air conditioning, outside of the treatment enclosure, although significantly lowering skin and ambient temperatures, did not affect the heart rates significantly. PUVA therapy is associated with a definite cardiovascular stress when the box type of therapeutic unit is used. Possible modifications are discussed.

    Sleep deprivation (SD) has become a relevant health problem in modern societies. We can be sleep deprived due to lifestyle habits or due to sleep disorders, such as insomnia, obstructive sleep apnea (OSA) and neurological disorders. One of the common element of sleep disorders is the condition of chronic SD, which has complex biological consequences. SD is capable of inducing different biological effects, such as neural autonomic control changes, increased oxidative stress, altered inflammatory and coagulatory responses and accelerated atherosclerosis. All these mechanisms links SD and cardiovascular and metabolic disorders. Epidemiological studies have shown that short sleep duration is associated with increased incidence of cardiovascular diseases, such as coronary artery disease, hypertension, arrhythmias, diabetes and obesity, after adjustment for socioeconomic and demographic risk factors and comorbidities. Thus, an early assessment of a condition of SD and its treatment is clinically relevant to prevent the harmful consequences of a very common condition in adult population.

    2016-01-01

    Full Text Available Introduction: Cross-border firing are increasingly being common in the modern era. The injuries resulting from these low intensity conflicts are a source of anxiety among treating physicians and their respective governments. The provisions are required to minimise the suffering of the victims viz. Mode of injuries, mortality patterns, adequacy of treatment at pre-hospital and tertiary care hospital and provisions to decrease morbidity and mortality for the people living in these areas. Materials and Methods: A retrospective study was conducted in GMCH, Jammu who suffered injuries due to cross border firing in the month of October, 2014. 68 patients were reported in the causality wing. All the patients were referred from level 2 trauma centre. There were 51 males and 17 females out of which 5 were children. The cause of injury, involvement of organ system, cause of mortality and morbidity and loopholes in prehospital management were identified. Results: Sharpnel were the most common cause of injury followed by indirect trauma. The common cause of mortality was abdominal and thoracic injuries. There were 4 deaths at hospital 2 of which were brought dead and 2 died during the course of treatment. There were twenty patients with extremity injuries, fourteen with chest trauma, eleven with abdomen including parineal injuries, three with head injuries, eight with ENT injuries, three with eye injuries and nine with splinters in the back out of which two were in the spinal canal. Conclusion: Prehospital stabilisation, early transport, in-transit resuscitation, immediate surgery if required and implementation of triage model and ATLS protocol has been the key to reduce mortality and morbidity.

  6. Vitamin E and cardiovascular disease.

    Saremi, Adonis; Arora, Rohit

    2010-01-01

    The objective of this article is to review the role of vitamin E in cardiovascular disease. We begin by describing the general characteristics and metabolism of vitamin E and the pathogenesis of atherosclerosis as it relates to oxidation. We also discuss key in vitro studies, animal studies, observational studies, and clinical trials regarding the potentially cardioprotective effect of vitamin E. Lastly, we outline the current recommendations regarding vitamin E in the prevention and treatment of cardiovascular disease as stated by the American Heart Association. Vitamin E is a fat-soluble antioxidant vitamin and alpha-tocopherol is its most naturally abundant and active form. Oxidation is a key step in atherogenesis. Oxidized low-density lipoprotein stimulates endothelial cells to produce inflammatory markers, is involved in foam cell formation, has cytotoxic effects on endothelial cells, inhibits the motility of tissue macrophages, and inhibits nitric oxide-induced vasodilatation. Vitamin E has been shown to increase oxidative resistance in vitro and prevent atherosclerotic plaque formation in mouse models. Consumption of foods rich in vitamin E has been associated with lower risk of coronary heart disease in middle-aged to older men and women. Clinical studies at large have not demonstrated a benefit of vitamin E in the primary and secondary prevention of cardiovascular disease. Vitamin E supplementation might be associated with an increase in total mortality, heart failure, and hemorrhagic stroke. The American Heart Association does not support the use of vitamin E supplements to prevent cardiovascular disease, but does recommend the consumption of foods abundant in antioxidant vitamins and other nutrients.

    Pharmacogenetics primarily uses genetic variation to identify subgroups of patients who may respond differently to a certain medication. Since its first description, the field of pharmacogenetics has expanded to study a broad range of cardiovascular drugs and has become a mainstream research discipline. Three principle classes of pharmacogenetic markers have emerged: 1) pharmacokinetic; 2) pharmacodynamic; and 3) underlying disease mechanism. In the realm of cardiovascular pharmacogenetics, significant advances have identified markers in each class for a variety of therapeutics, some with a potential for improving patient outcomes. While ongoing clinical trials will determine if routine use of pharmacogenetic testing may be beneficial, the data today support pharmacogenetic testing for certain variants on an individualized, case-by-case basis. Our primary goal is to review the association data for the major pharmacogenetic variants associated with commonly used cardiovascular medications: antiplatelet agents, warfarin, statins, beta-blockers, diuretics, and antiarrhythmic drugs. In addition, we highlight which variants and in which contexts pharmacogenetic testing can be implemented by practicing clinicians. The pace of genetic discovery has outstripped the generation of the evidence justifying its clinical adoption. Until the evidentiary gaps are filled, however, clinicians may choose to target therapeutics to individual patients whose genetic background indicates that they stand to benefit the most from pharmacogenetic testing.

    Coffee is the most widely consumed beverage worldwide and is only second to water drinking and is consumed by 83% of adults in the United States. The long-held controversy regarding the association of coffee consumption with an increased incidence of cardiovascular diseases (CVDs) and hypertension has been reversed by several recent prospective cohort studies and meta-analyses, which have demonstrated that coffee consumption is not associated with increased incidence of CVDs and hypertension and instead it could have a beneficial effect. To get a better understanding of the effects of coffee consumption on cardiovascular health, a Medline search of the English language literature was conducted from 2010 to early 2015 and 25 pertinent reports with information on the effects of coffee drinking, the incidence of CVDs, and hypertension and its mechanism of action were selected for inclusion in this commentary. These studies have shown either a neutral or beneficial effect of coffee on cardiovascular health. In conclusion, coffee is safe to drink by both normal subjects and by those with preexisting CVDs and hypertension.

    A significant body of evidence demonstrates that diets rich in fruits and vegetables promote health and attenuate, or delay, the onset of various diseases, including cardiovascular disease, diabetes, certain cancers, and several other age-related degenerative disorders. The concept that moderate chocolate consumption could be part of a healthy diet has gained acceptance in past years based on the health benefits ascribed to selected cocoa components. Specifically, cocoa as a plant and chocolate as food contain a series of chemicals that can interact with cell and tissue components, providing protection against the development and amelioration of pathological conditions. The most relevant effects of cocoa and chocolate have been related to cardiovascular disease. The mechanisms behind these effects are still under investigation. However, the maintenance or restoration of vascular NO production and bioavailability and the antioxidant effects are the mechanisms most consistently supported by experimental data. This review will summarize the most recent research on the cardiovascular effects of cocoa flavanols and related compounds.

    Robotic technology has been used in cardiovascular medicine since the late 1990s. Interventional cardiology, electrophysiology, endovascular surgery, minimally invasive cardiac surgery, and laparoscopic vascular surgery are all fields of application. Robotic devices enable endoscopic reconstructive surgery in narrow spaces and fast, very precise placement of catheters and devices in catheter-based interventions. In all robotic systems, the operator manipulates the robotic arms from a control station or console. In the field of cardiac surgery, mitral valve repair, CABG surgery, atrial septal defect repair, and myxoma resection can be achieved using robotic technology. Furthermore, vascular surgeons can perform a variety of robotically assisted operations to treat aortic, visceral, and peripheral artery disease. In electrophysiology, ablation procedures for atrial fibrillation can be carried out with robotic support. In the past few years, robotically assisted percutaneous coronary intervention and abdominal aortic endovascular surgery techniques have been developed. The basic feasibility and safety of robotic approaches in cardiovascular medicine has been demonstrated, but learning curves and the high costs associated with this technology have limited its widespread use. Nonetheless, increased procedural speed, accuracy, and reduced exposure to radiation and contrast agent in robotically assisted catheter-based interventions, as well as reduced surgical trauma and shortened patient recovery times after robotic cardiovascular surgery are promising achievements in the field.

    Research and development of new drugs requires both long time and high costs, whereas safety and tolerability profiles make the success rate of approval very low. Drug repurposing, applying known drugs and compounds to new indications, has been noted recently as a cost-effective and time-unconsuming way in developing new drugs, because they have already been proven safe in humans. In this review, we discuss drug repurposing of approved cardiovascular drugs, such as aspirin, beta-blockers, angiotensin converting enzyme inhibitors, angiotensin II receptor blockers, cardiac glycosides and statins. Regarding anti-tumor activities of these agents, a number of experimental studies have demonstrated promising pleiotropic properties, whereas all clinical trials have not shown expected results. In pathological conditions other than cancer, repurposing of cardiovascular drugs is also expanding. Numerous experimental studies have reported possibilities of drug repurposing in this field and some of them have been tried for new indications ('bench to bedside'), while unexpected results of clinical studies have given hints for drug repurposing and some unknown mechanisms of action have been demonstrated by experimental studies ('bedside to bench'). The future perspective of experimental and clinical studies using cardiovascular drugs are also discussed.

    Pseudoexfoliation(PEX) syndrome is a well-recognized late-onset disease caused by a generalized fibrillopathy. It is linked to a broad spectrum of ocular complications including glaucoma and perioperative problems during cataract surgery. Apart from the long-known intraocular manifestations, PEX deposits have been found in a variety of extraocular locations and they appear to represent a systemic process associated with increased cardiovascular and cerebrovascular morbidity. However, as published results are inconsistent, the clinical significance of the extraocular PEX deposits remains controversial. Identification of PEX deposits in the heart and the vessel wall, epidemiologic studies, as well as, similarities in pathogenetic mechanisms have led to the hypothesis of a possible relation between fibrillar material and cardiovascular disease. Recent studies suggest that PEX syndrome is frequently linked to impaired heart and blood vessels function. Systemic and ocular blood flow changes, altered parasympathetic vascular control and baroreflex sensitivity, increased vascular resistance and decreased blood flow velocity, arterial endothelial dysfunction, high levels of plasma homocysteine and arterial hypertension have all been demonstrated in PEX subjects. Common features in the pathogenesis of both atherosclerosis and PEX, like oxidative stress and inflammation and a possible higher frequency of abdominal aorta aneurysm in PEX patients, could imply that these grey-white deposits and cardiovascular disorders are related or reflect different manifestations of the same process.

    Air pollution is associated with increased cardiovascular morbidity and mortality. Recent experimental and epidemiologic studies show that particulate matter (PM) air pollution with PM10 or inhalable (thoracic) particles (mean aerodynamic diameter particles (aerodynamic diameter biological mechanisms responsible for adverse cardiovascular outcomes associated with PM have been described, including the release of pro-oxidative and pro-inflammatory mediators from the lungs into the circulation, autonomic nervous system imbalance, and the direct actions on the heart and vasculature of ultrafine particles translocated into the systemic circulation. The induction of oxidative stress by these particles may be central to all of these putative pathways that trigger coagulation and thrombosis, increased heart rate and reduced heart rate variability, endothelial dysfunction, arterial vasoconstriction, apoptosis, and hypertension. In chronic exposures these alterations favor the development and progression of atherosclerosis and possibly of hypertension in the long term, and in the short term acute exposures contribute to plaque instability, affect various traditional risk factors and trigger acute cardiovascular events (myocardial ischemia and infarction, stroke, heart failure, arrhythmias, and sudden death), particularly in high-risk subjects. There are currently also significant concerns with the risks of engineered nanoparticles.

    Basketball is one of the most popular sports in the United States and throughout the world, and therefore represents one of the most common sources of sports-related injuries. Basketball injuries should be managed by the same general rehabilitation principles as other sports injuries. Additionally, the clinician should be aware not only of general sports injuries but of those injuries most commonly seen in basketball players. By maintaining knowledge of the most common basketball injuries as well as their diagnosis and treatment, the clinician can help to optimize the athlete's return to play and enjoyment of the sport.

    Maxillofacial injuries occur in contact and noncontact sports. Despite advancements in protective equipment and rule changes, there is still an unacceptably high rate of maxillofacial injuries. These injuries are clinically challenging. The significant morbidity, deformity, and disability associated with these injuries can be avoided by their prompt diagnosis and appropriate management. It is important for the sports medicine professional to be competent in the correct diagnosis and management of maxillofacial injuries. This article reviews some of the major maxillofacial injuries, along with their emergent examinations and treatments.

    This paper proposes a new technology,``a bodygraphic injury surveillance system (BISS)'' that not only accumulates accident situation data but also represents injury data based on a human body coordinate system in a standardized and multilayered way. Standardized and multilayered representation of injury enables accumulation, retrieval, sharing, statistical analysis, and modeling causalities of injury across different fields such as medicine, engineering, and industry. To confirm the effectiveness of the developed system, the authors collected 3,685 children's injury data in cooperation with a hospital. As new analyses based on the developed BISS, this paper shows bodygraphically statistical analysis and childhood injury modeling using the developed BISS and Bayesian network technology.
