    and mortality 3. Most of the evidence comes from studies of ambient particles concentrations. However, in Europe and elsewhere, the air pollution profile has gradually changed toward a more pronounced photochemical component. Ozone is one of the most toxic components of the photochemical air pollution mixture. Indeed, the biological basis for these observations has not been elucidated. In the present review, the role of ozone as chemical molecule will be firstly considered. Secondly, pathogenetic mechanisms connecting the atmospheric ozone level and cardiovascular pathology will be examined. Thirdly, the literature relating hospitalization frequency, morbidity and mortality due to cardiovascular causes and ozone concentration will be studied. The correlation between ozone level and occurrence of acute myocardial infarction will be eventually discussed.

    Each year in the United States, an estimated 800 to 1,400 people are murdered at work, and an unknown number of nonfatal injuries due to workplace violence occur. Based on Ohio's workers' compensation claims from 1983 through 1985, police officers, gasoline service station employees, employees of the real estate industry, and hotel/motel employees were found to be at the highest risk for occupational violent crime (OVC) injury and death. Grocery store employees, specifically those working in convenience food stores, and employees of the real estate industry had the most reported rapes. Four previously unidentified industries at increased risk of employee victimization were described. Identification of industries and occupations at high risk for crime victimization provides the opportunity to focus preventive strategies to promote employee safety and security in the workplace.

    Cardiovascular diseases ralely evoke nephrotic syndrome. Especially hypertensive renal disease (nephroscrelosis) and renovascular hypertension occasionally may lead to nephrotic syndrome. We reported a case of nephrotic syndrome with renovascular hypertension successfully treated with candesartan. In eldery patients cardiovascular diseases are appeared. It is very important for clinicians to detect the mechanism of nephrotic syndrome caused by cardiovascular diseases. PMID:15500142

    Electrical injuries are most commonly due to household accidents.Various factors determine the severity of electric injury, including type of current, amperage, voltage, tissue resistance, pathway of current,and duration of contact with the body. Various types of neurologic damage due to electrical injury have been described in literature. It may manifest as peripheral nerve injury, spinal cord damage, seizures, cerebellarataxia, hypoxic encephalopathy, and intracerebral hemorrhage. Acute ischemic stroke is an infrequent complication of electrical injury. Herein,we report a case of middle-aged man, who accidentally sustained high voltage electrical injury followed by acute vertebrobasilar ischemic stroke. Magnetic resonance imaging of the brain showed acute infarctin bilateral cerebellar and medial occipital regions. Computed tomographic angiogram of the brain and neck vessels was normal. Possibly,in our patient, the mechanism could be related to direct vascular injury due to electric current. PMID:25684743

    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.

    Kidney damage is a common sequela of several chronic pathologic conditions. Whether biomarkers of kidney damage are prognostic for more severe outcomes is unknown. We measured three urinary biomarkers (kidney injury molecule-1 [KIM-1], IL-18, and albumin) in 3010 individuals enrolled in the Health, Aging and Body Composition (Health ABC) study and used Cox proportional hazards models to investigate the associations of urinary KIM-1/creatinine (cr), IL-18/cr, and albumin/cr (ACR) with all-cause mortality and cardiovascular disease (CVD). Multivariable models adjusted for demographics, traditional CVD risk factors, and eGFR. Mean age of participants was 74 years, 49% of participants were men, and 41% of participants were black. During the median 12.4 years of follow-up, 1450 deaths and 797 CVD outcomes occurred. Compared with the lowest quartile, successive quartiles had the following adjusted hazard ratios (HRs; 95% confidence intervals [95% CIs]) for mortality: KIM-1/cr: (1.21; 1.03 to 1.41), (1.13; 0.96 to 1.34), and (1.28; 1.08 to 1.52); IL-18/cr: (1.02; 0.88 to 1.19), (1.16; 0.99 to 1.35), and (1.06; 0.90 to 1.25); ACR: (1.08; 0.91 to 1.27), (1.24; 1.06 to 1.46), and (1.63; 1.39 to 1.91). In similar analyses, only ACR quartiles associated with CVD: (1.19; 0.95 to 1.48), (1.35; 1.08 to 1.67), and (1.54; 1.24 to 1.91). Urinary KIM-1 had a modest association with all-cause mortality but did not associate with CVD, and urinary IL-18 did not associate with either outcome. In contrast, albuminuria strongly associated with all-cause mortality and CVD. Future studies should evaluate reasons for these differences in the prognostic importance of individual kidney injury markers. PMID:24511130

    Centipede bites have been reported to cause localized and/or systemic symptoms including local pain, erythema and edema, nausea and vomiting, palpitations, headache, lymphadenopathy, and rhabdomyolysis. However, acute myocardial infarction due to centipede envenomation is reported in only three cases in English medical literature.We present a case of 31-year-old male bitten by a golden colored centipede leading to myocardial infarction and cardiopulmonary arrest which is seen very rarely. The patient was admitted to emergency department with a swollen and painful right foot. However, typical chest pain became the major complaint and cardiopulmonary arrest developed while electrocardiography was being obtained. The patient was resuscitated successfully for 5 min and acute infero-posterolateral myocardial infarction was detected on electrocardiography. PMID:25994876

    Full Text Available Although considerable research has been devoted to cognitive functions deteriorating due to diseases of cardiovascular system, rather less attention has been paid to their theoretical background. Progressive vascular disorders as hypertension, atherosclerosis and carotid artery stenosis generate most of all pathological changes in the white matter, that cause specific cognitive disorder: disconnection syndromes, and disturbances in the dynamic aspect of information processing. These features made neuropsychological disorders secondary to cardiovascular diseases different than the effects of cerebral cortex damage, which may be interpreted modularly.

    1998-10-01

    We hypothesized that acute brain injury results in decreased heart rate (HR) variability and baroreflex sensitivity indicative of uncoupling of the autonomic and cardiovascular systems and that the degree of uncoupling should be proportional to the degree of neurological injury. We used HR and blood pressure (BP) power spectral analysis to measure neuroautonomic regulation of HR and BP and the transfer function magnitude (TF) between BP and HR as a measure of baroreflex modulation of HR. In 24 brain-injured patients [anoxic/ischemic injury (n = 7), multiple trauma (n = 6), head trauma (n = 5), central nervous system infection (n = 4), and intracranial hemorrhage (n = 2)], neurological injury and survival was associated with low-frequency (0.01-0.15 Hz) HR and BP power and TF. Brain-dead patients showed decreased low-frequency HR power [0. 51 +/- 0.36 (SE) vs. 2.54 +/- 0.14 beats/min2, P = 0.03] and TF [0. 61 +/- 0.16 (SE) vs. 1.29 +/- 0.07 beats . min-1 . mmHg-1, P = 0.05] compared with non-brain-dead patients. We conclude that 1) severity of neurological injury and outcome are inversely associated with HR and BP variability and 2) there is direct evidence for cardiovascular and autonomic uncoupling in acute brain injury with complete uncoupling during brain death.

    Full Text Available A 20-year-old woman, who was found unconscious in the bed by the morning, was brought to emergency department. Her carboxyhemoglobin level was 20.2%. The portable chest X-ray showed bilaterally alveolar and interstitial infiltration. Initial pO 2 /FIO 2 ratio was calculated as 119 mmHg. Acute lung injury due to carbon monoxide intoxication was considered. She was intubated and mechanical ventilation was applied. In the second day of hospitalization, a clear improvement was observed on the chest X-ray. She was discharged without any complication on the seventh day of hospitalization. Early diagnosis and treatment may prevent progression of ARDS and progression of permanent damage, and may lead to complete recovery.

    2009-02-01

    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.

When the emergency technician arrived, the patient was in a state of cardiopulmonary arrest. On arrival, his electrocardiogram showed asystole. His body showed swelling with subcutaneous hemorrhage, suggesting multiple contusional wounds. Serum biochemistry evaluation revealed blood urea nitrogen of 80 mg/dL, creatinine of 5.99 mg/dL, creatine phosphokinase of 10,094 IU/L, and potassium of 11.0 mEq/L. Advanced cardiopulmonary resuscitation failed to obtain a return of spontaneous circulation. Laboratory findings revealed rhabdomyolysis, renal failure, and hyperkalemia. Autopsy did not indicate the direct cause of death to be traumatic organ injuries. Because trauma was not the direct reason of death, we speculated that the patient died of hyperkalemia induced by multiple contusional soft tissue injuries, following rhabdomyolysis, hemolysis, and acute renal failure. The physician should maintain a high index of suspicion for hyperkalemia induced by rhabdomyolysis and acute renal failure, especially in patients presenting with symptoms of multiple soft tissue injuries with massive subcutaneous hemorrhaging.Keywords: contusion, rhabdomyolysis, renal failure, hyperkalemia

    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.

    Full Text Available AIM: The aim of this study is to determine injury types and the causes of injury and to evaluate the injury's results in term of public health. METHODS: Mersin University Medical Faculty Forensic Medicine Department's legal reports of year 2010 were evaluated for this descriptive study. Demographic features, causes of injury, injury style, date and place of injury, injured body part, the hospitalization need due to injury, clinics where injured patients were hospitalized (if any, hospitalization duration were obtained. Data are presented as mean+/- standard deviation and in percentages. RESULTS: There were 1042 reported forensic injury cases in 2010. 67.7% of them are male, 32.3% are female, average age is 26.6+/-16.8. Injuries occurred due to traffic accidents, sharp objects, assault and poisoning, respectively. The first place belongs to traffic accidents (both for males and females, second place belongs to poison for females and sharp objects for males. The reasons of injuries; the ranking is accidents, interpersonal violence and suicides respectively for women while for accident, interpersonal violence and industrial accidents respectively for men. Accident is first ranked reason for every age group. Suicide was seen most frequently between 15-19th years for females. Suicide was determined in females 5-8 times more than males in all of age groups. CONCLUSION: Accidents and interpersonal violence were first two reasons of injury. The first protection method for injuries in traffic accidents was prevention from accidents. If it is not possible, injury's prevention is other precaution. Public trainings must be organized in these topics. Besides, families must receive consultancy about girls' tendency to self damages in especially adolescent era.

    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.

    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.

    Full Text Available We aimed to present two consecutive fall cases in order to remind importance of  fall precautions. Two patients were injured in traffic accidents in two different cities, during transportation to university hospitals. They had different malignancies and were coming to receive their chemotherapy. Both patients were admitted to our surgical clinic for close observation due to the traffic accidents. They fell from their beds in the ward during the night shift in the first 24 hours after admission. They were treated for additional trauma and more time and source was spent for diagnosis and treatment. Thus their main oncologic treatments were delayed.

    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.

    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. The aim of the study was to examine neurocognitive correlates of PC. The sample included children (n=177) aged 5-14 years with traumatic brain injury from consecutive admissions to 5 trauma centers were followed prospectively at baseline and 6 months with semi-structured 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 26/141 (18%) participants assessed at 6 months post-injury. Attention, processing speed, verbal memory, IQ, and executive function, were significantly associated (p < .05) with PC even after socioeconomic status, injury severity, and pre-injury 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. PMID:26185905

    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.

    The use of various FES protocols to encourage increases in physical activity and to augment physical fitness and reduce heart disease risk is a relatively new, but growing field of investigation. The evidence so far supports its use in improving potential health benefits for patients with SCI. Such benefits may include more efficient and safer cardiac function; greater stimulus for metabolic, cardiovascular, and pulmonary training adaptations; and greater stimulus for skeletal muscle training adaptations. In addition, the availability of relatively inexpensive commercial FES units to elicit muscular contractions, the ease of use of gel-less, reusable electrodes, and the increasing popularity of home and commercial upper body exercise equipment mean that such benefits are likely to be more accessible to the SCI population through increased convenience and decreased cost. The US Department of Health and Human Services has identified those with SCI as a "special population" whose health problems are accentuated, and so need to be specifically addressed. FES presents "a clear opportunity.... For health promotion and disease prevention efforts to improve the health prospects and functional independence of people with disabilities." As a corollary to this, the Centers for Disease Control and Prevention have recommended the development of techniques to prevent or ameliorate secondary disabilities in persons with a SCI. Patients with SCI have an increased susceptibility to cardiac morbidity and mortality in the acute and early stages of their injury. Most of these patients make an excellent adaptation except when confronted with infection or hypoxia. SCI by itself does not promote atherosclerosis; however, in association with multiple secondary conditions related to SCI, along with advancing age, patients with SCI are predisposed to relatively greater risk of heart disease. The epidemiologic significance of this is reflected in demographic studies that indicate an

    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.

  9. Assessing the Risk of Crew Injury Due to Dynamic Loads During Spaceflight

    Spaceflight requires tremendous amounts of energy to achieve Earth orbit and to attain escape velocity for interplanetary missions. Although the majority of the energy is managed in such a way as to limit the accelerations on the crew, several mission phases may result in crew exposure to dynamic loads. In the automotive industry, risk of serious injury can be tolerated because the probability of a crash is remote each time a person enters a vehicle, resulting in a low total risk of injury. For spaceflight, the level of acceptable injury risk must be lower to achieve a low total risk of injury because the dynamic loads are expected on each flight. To mitigate the risk of injury due to dynamic loads, the NASA Human Research Program has developed a research plan to inform the knowledge gaps and develop relevant tools for assessing injury risk. The risk of injury due to dynamic loads can be further subdivided into extrinsic and intrinsic risk factors. Extrinsic risk factors include the vehicle dynamic profile, seat and restraint design, and spacesuit design. Human tolerance to loads varies considerably depending on the direction, amplitude, and rise-time of acceleration therefore the orientation of the body to the dynamic vector is critical to determining crew risk of injury. Although a particular vehicle dynamic profile may be safe for a particular design, the seat, restraint, and suit designs can affect the risk of injury due to localized effects. In addition, characteristics intrinsic to the crewmember may also contribute to the risk of injury, such as crewmember sex, age, anthropometry, and deconditioning due to spaceflight, and each astronaut may have a different risk profile because of these factors. The purpose of the research plan is to address any knowledge gaps in the risk factors to mitigate injury risk. Methods for assessing injury risk have been well documented in other analogous industries and include human volunteer testing, human exposure to dynamic

    Mammalian platelets are small, anuclear circulating cells that form tightly adherent, shear-resistant thrombi to prevent blood loss after vessel injury. Platelet thrombi that form in coronary and carotid arteries also underlie common vascular diseases such as myocardial infarction and stroke and are the target of drugs used to treat these diseases. Birds have high-pressure cardiovascular systems like mammals but generate nucleated thrombocytes rather than platelets. Here, we show that avian t...

  11. Effects of customized risk reduction program on cardiovascular risk in males with spinal cord injury

    Directory of Open Access Journals (Sweden)

    Jonathan Myers, PhD

    2012-12-01

    Full Text Available Persons with spinal cord injury (SCI have heightened risk for cardiovascular disease (CVD. Multidisciplinary risk reduction programs using case management models have been effective in reducing CVD risk in nondisabled persons, but little is known regarding the effects of such programs in SCI. Twenty-six persons with SCI underwent a pilot 2 yr risk intervention program including frequent telephone contact by a case manager and in-person visits by a dietitian, physical therapist, and exercise physiologist. At 6 mo intervals, measurements were made of dietary intake, glucose and lipids, physical activity patterns, and exercise capacity. Of the 26 participants, 10 remained in the program for the full 2 yr; medical issues unrelated to the program were the major reasons for dropping out. Significant improvements were observed in weight, plasma insulin, homeostatic model assessment insulin resistance, and total cholesterol/high-density lipoprotein ratio, although these changes were not consistent across visits. No differences in estimates of physical activity patterns were demonstrated, nor were differences in dietary macronutrient intake observed. Thus, modest changes in some CVD risk markers can be achieved by a multidisciplinary risk reduction program in SCI. Such programs present more challenges than in ambulatory persons, and more intensive risk intervention may be required to appreciably reduce CVD risk in SCI.

    Background Recently lumbopelvic control has been linked to pitching performance, kinematics and loading; however, poor lumbopelvic control has not been prospectively investigated as a risk factor for injury in baseball pitchers. Hypothesis Pitchers with poor lumbopelvic control during spring training are more likely to miss 30 or more days due to injury through an entire baseball season than pitchers with good lumbopelvic control. Study design Cohort study. Methods Three hundred forty-seven professional baseball pitchers were enrolled into the study during the last 2 weeks of spring training and stayed with the same team for the entire season. Lumbopelvic control was quantified by peak anterior-posterior deviation of the pelvis relative to starting position during a single leg raise test (APScore). Days missed due to injury through the entire season were recorded by each team's medical staff. Results Higher APScore was significantly associated with a higher likelihood of missing 30 days or more (Chi-Square, p=0.023). When divided into tertiles based on their APScore, participants in the highest tertile were 3.0 times and 2.2 times more likely to miss at least 30 days throughout the course of a baseball season relative to those in the lowest or middle tertiles, respectively. Higher APScore was also significantly associated with missing more days due to injury within participants who missed at least one day to injury (ANOVA, p=0.018), with the highest tertile missing significantly more days (mean=98.6 d) than the middle tertile (mean=45.8d, p=0.017) or the lowest tertile (mean=43.8, p=0.017). Conclusion This study found that poor lumbopelvic control in professional pitchers was associated with increased risk of missing significant time due to injury. PMID:25159541

    There is little documentation of the potential catastrophic effects of injuries on families due to out of pocket (OOP) expenditure for medical care. Patients who were admitted for at least one night in a tertiary care hospital of Chandigarh city due to injury were recruited and were followed-up at 1, 2 and 12 months after discharge to collect information on OOP expenditure. Out of the total 227 patients, 60% (137/227) had sustained road traffic injuries (RTI). The average OOP expenditure per hospitalisation and up to 12 months post discharge was USD 388 (95% CI: 332-441) and USD 1046 (95% CI: 871-1221) respectively. Mean OOP expenditure for RTI and non-RTI cases during hospitalisation was USD 400 (95% CI: 344-456) and USD 369 (95% CI: 313-425) respectively. The prevalence of catastrophic expenditure was 30%, and was significantly higher among those belonging to the lowest income quartile (OR-26.50, 95% CI: 6.70-105.07, p-value: <0.01) and with an inpatient stay greater than 7 days (OR-10.60, 95% CI: 4.21-26.64, p-value: <0.01). High OOP expenditure for treatment of injury puts a significant economic burden on families. Measures aimed at increasing public health spending for prevention of injury and providing financial risk protection are urgently required in India. PMID:27384572

Among these, 85 patients were male and 55 were female. The medial meniscus was the most affected site (92% of the cases. RESULTS: All these injuries were diagnosed by means of clinical examination and magnetic resonance imaging. The patients underwent meniscectomy by means of arthroscopy and the results were divided into two types: good and poor. Poor results were found in 27% of the cases, among which nine patients progressed to idiopathic osteonecrosis. CONCLUSION: We conclude that

  20. Primary oculomotor nerve palsy due to mild head injury. Report of two cases

    International Nuclear Information System (INIS)

    Two patients with primary oculomotor nerve palsy due to direct mild head injury are reported. They presented with internal ophthalmoplegia, dilated nonreactive pupils, and very mild disturbance in consciousness. Except for the persistent oculomotor nerve palsy, both the patients recovered fully within one week. Neither demonstrated a history that was suggestive of a cause for their oculomotor nerve palsy. Initial CT scans demonstrated localized subarachnoid hemorrhage around the brain stem. One of the patients had sustained a fracture of the anterior clinoid process. As the underlying pathophysiologic mechanism underlying the oculomotor nerve palsy we suspected mild injury to the pupillomotor fibers at the anterior petroclinoidal ligament and that of the pupillary fibers at the posterior petroclinoidal ligament. We speculate that these perforating fibers at the anterior petroclinoidal ligament acted as a fulcrum due to downward displacement of the brainstem at the time of impact. (author)

    Penetrating brain injury caused by a high speed projectile is rather rare in Japan, known for its strict gun-control laws. We report a case of a 55-year-old male, who was transferred to our hospital with a foreign body in the brain due to penetrating head injury, which was caused by an explosion of a construction machine. Neurological examination demonstrated severe motor aphagia with no apparent motor paresis. The patient had a scalp laceration on his left forehead with exposed cerebral tissue and CSF leakage. Head CT scan and plain skull X-ray revealed a 20 mm×25 mm bolt which had penetrated due to the explosion of the machine. The anterior wall of the left frontal sinus was fractured resulting in dural laceration, and scattered bone fragments were seen along the trajectory of the bolt. Digital subtraction angiography showed no significant vascular injuries including superior sagittal sinus. We performed open surgery, and successfully removed the bolt along with the damaged frontal lobe. The patient had no infection or seizure after the surgery, and was transferred for further rehabilitation therapy. We performed a cosmetic cranioplasty six months later. Surgical debridement of the damaged cerebral tissue along the trajectory led to successful removal of the bolt with no further neurological deficit. PMID:22538284

A 74-year-old man with a 15-year history of diabetes mellitus was refilling a container with household detergent at home. He splashed the detergent in his eyes. Slit-lamp examination revealed extensive epithelial damage to the left eye, leading to a persistent corneal epithelial defect. We used a bandage soft contact lens with levofloxacin eye drops as concomitant therapy in order to promote healing. However, a strain of fluoroquinolone-resistant Corynebacterium colonized the eye, so that the corneal ulcer eventually became severe. Use of the bandage soft contact lens was discontinued. His antimicrobial agent was changed to cefmenoxime, a drug to which fluoroquinolone-resistant Corynebacterium is sensitive, and topical instillation of autologous serum subsequently promoted improvement of the ulcer. On day 38 after injury, iris rubeosis led to hyphema and ghost cell glaucoma. With improvement of his corneal epithelial defect, the iris rubeosis and hyphema regressed and his visual acuity improved to 20/25 on the left eye. To the best of our knowledge, this is the first report of a case resulting in severe complications due to chemical injury by a neutral detergent. Ophthalmologists should be aware that corneal epithelial damage may become prolonged in elderly patients with diabetes, and unexpectedly severe when wearing bandage soft contact lens, with infection of Corynebacterium resistant to fluoroquinolones, even if the chemical agent is a neutral detergent.Keywords: chemical injury, household detergent, persistent corneal

    2013-10-01

    A fall from high height can cause thoracolumbar spine fracture with retropulsion of endplate fragments into the canal leading to neurological deficit. Our objectives were to develop a hybrid cadaveric/surrogate model for producing thoracolumbar spine injury during simulated fall from height, evaluate the feasibility and performance of the model, and compare injuries with those observed clinically. Our model consisted of a 3-vertebra human lumbar specimen (L3-L4-L5) stabilized with muscle force replication and mounted within an impact dummy. The model was subjected to a fall from height of 2.2 m with impact velocity of 6.6 m/s. Kinetic and kinematic time-history responses were determined using spinal and pelvis load cell data and analyses of high-speed video. Injuries to the L4 vertebra were evaluated by fluoroscopy, radiography, and detailed anatomical dissection. Peak compression forces during the fall from height occurred at 7 ms and reached 44.7 kN at the ground, 9.1 kN at the pelvis, and 4.5 kN at the spine. Pelvis acceleration peaks reached 209.9 g at 8 ms for vertical and 62.8 g at 12 ms for rearward. Tensile load peaks were then observed (spine: 657.0 N at 47 ms; pelvis: 569.4 N at 61 ms). T1/pelvis peak flexion of 68.3° occurred at 38 ms as the upper torso translated forward while the pelvis translated rearward. Complete axial burst fracture of the L4 vertebra was observed including endplate comminution, retropulsion of bony fragments into the canal, loss of vertebral body height, and increased interpedicular distance due to fractures anterior to the pedicles and a vertical split fracture of the left lamina. Our dynamic injury model closely replicated the biomechanics of real-life fall from height and produced realistic, clinically relevant burst fracture of the lumbar spine. Our model may be used for further study of thoracolumbar spine injury mechanisms and injury prevention strategies. PMID:23792617

    Full Text Available Introduction: Vascularity of kidneys is very high, so these organs are potentially susceptible to be affected with toxins including snake venom. Hypersensitivity to snake venous could cause some neurological problem. Case Report: We present a 14-year-old boy with acute kidney injury (AKI due to snake bite. After a few days, kidney failure with hematuria was developed. His serum creatinine level rose to 3 mg/dl and following 2 weeks gradually and decreased to normal level without any special treatment except for anti-venom, which was not prescribed inappropriate time (this type of AKI is not reported previously. He had seizure attacks, which were according to magnetic resonance imaging due to posterior reversible encephalopathy syndrome (PRES (This neurologic complication has been seen in other kidney injuries but up to now it was not reported in snake bite victims. Conclusion: Sanke venom could cause PRES due to AKI and seizure could be one of the most important complications in snake bite.

Although MRI and polysomnography showed no abnormalities, (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) and (11)C flumazenil (FMZ)-PET revealed findings consistent with cerebral damage to the affected temporal region. The memory deficit of the patient gradually improved in parallel with the relief of the sleep-related symptoms. FDG-PET showed considerable improvement in glucose metabolism when he had recovered, however, evidence of neural loss remained in the FMZ-PET findings. PMID:22674950

    Full Text Available Heroin exposure can cause various complications like seizures, stroke, spongiform encephalopathy, transverse myelopathy, plexopathy, compartment syndrome, rhabdomyolysis and renal failure due to various mechanisms. We report here a young male who smoked heroin for the first time and developed transverse myelitis, rhabdomyolysis and acute kidney injury requiring dialysis. His renal recovery was complete by four weeks, while neurological improvement occurred 8 to 12 weeks later. This case suggests a common pathogenic mechanism of heroin intoxication involving multiple systems of the body.

  12. Risk assessment for cardiovascular and respiratory mortality due to air pollution and synoptic meteorology in 10 Canadian cities

    International Nuclear Information System (INIS)

    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. -- Air pollution has a greater influence on acute human mortality than weather type, with significant differences in risk from exposure to gaseous air pollution based on cause of death

    Background Health expenditures are a major financial burden for many persons in low and middle-income countries, where individuals often lack health insurance. We estimate the effect of purchasing cardiovascular medicines on poverty in low and middle-income populations using rural and urban India as an example. Methods We created step-up treatment regimens for prevention of ischemic heart disease for the most common cardiovascular medications in India based on their cost and relative risk reduction. Cost was measured by Government of India mandated ceiling prices in rupees (Rs. 1 = $0·016) for essential medicines plus taxes. We calculated step-wise projected incidence and intensity of impoverishment due to medicine purchase. To do this we measured the resources available to individuals as daily per-capita expenditures from the latest National Sample Survey, subtracted daily medication costs, and compared this to 2014 poverty thresholds recommended by an expert group. Findings Analysis of cost-effectiveness resulted in five primary prevention drug regimens, created by progressive addition of Aspirin 75 mg, Hydrochlorothiazide 12.5mg, Losartan 25 mg, and Atorvastatin 10 mg or 40mg. Daily cost from steps 1 to 5 increased from Rs. 0·13, Rs. 1.16, Rs. 3.81, Rs. 10.07, to Rs. 28.85. At baseline, 31% of rural and 27% percent of urban Indian population are poor at the designated poverty thresholds. The Rs. 28.85 regimen would be unaffordable to 81% and 58% of rural and urban people. A secondary prevention regimen with aspirin, hydrochlorothiazide, atenolol and atorvastatin could be unaffordable to 81% and 57% rural and urban people respectively. According to our estimates, 17% of the rural 32% of the urban adult population could benefit with these medications, and their out of pocket purchase could impoverish 17 million rural and 10 million urban people in India and increase respective poverty gaps by 2.9%. Conclusion Medication costs for cardiovascular disease have the

    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.

    Traumatic hemothorax is usually associated with obvious organ injuries, such as rib fractures, pulmonary injuries, and other mediastinal injuries. We present a rare case in which a 42-year- old Korean man who fell off of a roof, approximately 3 meters in height, resulting in a life-threatening hemothorax without obvious injuries to the thoracic organs. Chest CT showed a large amount of hemothorax in the right side of the thoracic cavity, and an active bleeding, presumably from the posterior intercostal or the phrenic artery, with a focal aneurysmal change. The emergency thoracotomy was performed to bring the active bleeding under control. The operative findings showed there were only the inferior pulmonary ligament tears, and the active bleeding from it. The postoperative course was uneventful and the patient was discharged without any complications. We should consider the inferior pulmonary ligamental injury as one of causes for traumatic hemothorax. PMID:25885049

    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.

    Paraquat is a weed killer which causes often fatal lung damage in humans and other animals. There is evidence that the pulmonary surfactant system is involved in the pathophysiology of respiratory failure after paraquat intoxication and, therefore, the possible therapeutic effect of intratracheal surfactant administration on gas exchange in rats with progressive lung injury induced by paraquat poisoning was studied. In one group of rats, the time course of the development of lung injury due to paraquat intoxication was characterized. In a second group of rats, 72 h after paraquat intoxication, the animals underwent mechanical ventilation and only those animals in which the arterial oxygen tension/inspiratory oxygen fraction (Pa,O2/FI,O2) decreased to below 20 kPa (150 mmHg) received exogenous surfactant (200 mg x kg(-1) body weight). Within 3 days the rats in group 1 developed progressive respiratory failure, demonstrated not only by impaired gas exchange and lung mechanics but also by increased minimal surface tension and increased protein concentration in bronchoalveolar lavage fluid. In group 2, intratracheal surfactant administration increased Pa,O2/FI,O2 significantly within 5 min (14.4+/-2.4 kPa (108+/-18 mmHg)) to (55.2+/-53 kPa (414+/-40 mmHg)) and sustained this level for at least 2 h. It is concluded that intratracheal surfactant administration is a promising approach in the treatment of severe respiratory failure caused by paraquat poisoning. PMID:9727775

    We report a case of a 37-year-old man with Maturity Onset Diabetes of the Youth (MODY) type 5, admitted for an episode of cholestasis and a simultaneous acute kidney injury (AKI). Chronic liver disease was due to a mutation in the transcription factor 2 (TCF2) gene, thus highlighting the need for a close liver follow-up in these patients. AKI was attributed to a cholemic nephropathy based on the following rationale: (1) alternative diagnoses were actively ruled out; (2) the onset of AKI coincided with the onset of severe hyperbilirubinaemia; (3) renal pathology showed large bile tubular casts and a marked tubular necrosis and (4) creatinine serum dramatically decreased when bilirubin levels improved after the first sessions of extracorporeal albumin dialysis (ECAD), thus suggesting its role in renal recovery. Even though cholestasis can precipitate renal injury, the diagnosis of cholemic nephropathy could require a renal biopsy at times. Future studies should confirm the benefits of ECAD in cholemic nephropathy. PMID:27389722

    A high neutrophil-lymphocyte ratio (N/L ratio) was associated with the development of acute kidney injury (AKI) in patients with severe sepsis. We sought to investigate the association between the perioperative N/L ratios and postoperative AKI in patients undergoing high-risk cardiovascular surgery.A retrospective medical chart review was performed of 590 patients who underwent cardiovascular surgeries, including coronary artery bypass, valve replacement, patch closure for atrial or ventricular septal defect and surgery on the thoracic aorta with cardiopulmonary bypass (CPB). Baseline perioperative clinical parameters, including N/L ratios measured before surgery, immediately after surgery, and on postoperative day (POD) one were obtained. Multivariate logistic regression analysis was used to evaluate risk factors.A total of 166 patients (28.1%) developed AKI defined by the KDIGO (kidney disease improving global outcomes) criteria in the first 7 PODs. Independent risk factors for AKI included old age, decreased left ventricular systolic function, preoperative high serum creatinine, low serum albumin and high uric acid levels, intraoperative large transfusion amount, oliguria, hyperglycemia, and elevated N/L ratio measured immediately after surgery and on POD one. The quartiles of immediately postoperative N/L ratio were associated with graded increase in risk of AKI development (fourth quartile [N/L ratio≥10] multivariate odds ratio 5.90, 95% confidence interval [CI] 2.74-12.73; P work-up, can therefore assist with risk stratification of AKI and mortality in high-risk surgical patients.

    Statins as lipid lowering drugs, are safe and effective in reducing cardiovascular disease risk, but rarely produce myopathy like myalgia, myositis or rhabdomyolysis. We report the case of Rosuvastatin induced rhabdomyolytic acute renal failure and quadriparesis in a 67-year old male, a known case of type-2 diabetes mellitus and with a history of coronary angioplasty four months back. He was on antihypertensive, oral hypoglycemic and antiplatelet medications with Rosuvastatin 40mg/day. He was admitted with altered sensorium, breathlessness, vomiting, muscle weakness and decreased urine output and had raised serum creatinine, creatinine phosphokinase and myoglobin. After ruling out all other causation for rhabdomyolysis, we stopped Rosuvastatin and started supportive management and hemodialysis. Patient showed gradual recovery in renal function and quadriparesis. Patient was discharged with good urine output and on antihypertensive, hypoglycemic drug and diet restrictions for lipid control. He recovered completely and had normal renal function with well controlled lipid level on follow up of 6 months after discharge. Thus, prompt diagnosis of Rhabdomyolysis due to Rosuvastatin in absence of other aetiology and the multidisciplinary management can prevent further complication with favorable outcome. PMID:26155510

    Ischaemia/reperfusion (I/R) injury of the heart represents a major health burden mainly associated with acute coronary syndromes. While timely coronary reperfusion has become the established routine therapy in patients with ST-elevation myocardial infarction, the restoration of blood flow into the previously ischaemic area is always accompanied by myocardial injury. The central mechanism involved in this phenomenon is represented by the excessive generation of reactive oxygen species (ROS). Besides their harmful role when highly generated during early reperfusion, minimal ROS formation during ischaemia and/or at reperfusion is critical for the redox signaling of cardioprotection. In the past decades, mitochondria have emerged as the major source of ROS as well as a critical target for cardioprotective strategies at reperfusion. Mitochondria dysfunction associated with I/R myocardial injury is further described and ultimately analyzed with respect to its role as source of both deleterious and beneficial ROS. Furthermore, the contribution of ROS in the highly investigated field of conditioning strategies is analyzed. In the end, the vascular sources of mitochondria-derived ROS are briefly reviewed.

    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 expenditures and providing FRP, particularly for the middle class. The policy could also provide large government savings on health care. PMID:25841771

    Full Text Available An Injury of the caudal equine has been suggested to be an unique type of spinal injury than other types of penetrating spinal injuries. However the role of surgery as a method to speed or improve recovery is unclear. The 33 war wounded reported here represent approximately 15% of all penetrating spinal injuries related to Esfahan province. The average age was 23 years they were admitted at first in urgent centers near the war border and then in hospitals in different parts of country they received spine films and syelography. Deficit were Complete. if total loss of function existed and were "incomplete" if any function remained below the level of injury. Improvement at the end of follow up (after two years was defiend as any recovery of motor strength or sensory level. Early neurosurgical intervention for pentrating injuries of caudal equine may be beneficial but carries an increased risk of complications.

We report the second case of crescentic glomerulonephritis, causing acute kidney injury, in a pa...

  12. Difficulty in Clinical Evaluation of Radial Nerve Injury due to Multiple Trauma to the Humerus, Wrist, and Hand

    2014-01-01

    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.

    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.

    1998-03-01

    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

  16. 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. ...

  18. Increased mortality in schizophrenia due to cardiovascular disease – a non-systematic review of epidemiology, possible causes and interventions

    2014-09-01

    Full Text Available Background: Schizophrenia is among the major causes of disability worldwide and the mortality from cardiovascular disease (CVD is significantly elevated. There is a growing concern that this health challenge is not fully understood and efficiently addressed.Methods: Non-systematic review using searches in PubMed on relevant topics as well as selection of references based on the authors experience from clinical work and research in the field.Results: In most countries, the standardized mortality rate (SMR in schizophrenia is about 2.5, leading to a reduction in life expectancy between 15 and 20 years. A major contributor of the increased mortality is due to CVD, with CVD mortality ranging from 40-50% in most studies. Important causal factors are related to lifestyle, including poor diet, lack of physical activity, smoking and substance abuse. Recent findings suggest that there are overlapping pathophysiology and genetics between schizophrenia and CVD risk factors, further increasing the liability to CVD in schizophrenia. Many pharmacological agents used for treating psychotic disorders have side effects augmenting CVD risk. Although several CVD risk factors can be effectively prevented and treated, the provision of somatic health services to people with schizophrenia seems inadequate. Further, there is a sparseness of studies investigating the effects of life-style interventions in schizophrenia, and there is little knowledge about effective programs targeting physical health in this population. Discussion: The risk for CVD and CVD-related deaths in people with schizophrenia is increased, but the underlying mechanisms are not fully known. Coordinated interventions in different health care settings could probably reduce the risk. There is an urgent need to develop and implement effective programs to increase life expectancy in schizophrenia, and we argue that mental health workers should be more involved in this important task.

    Full Text Available Objectives To investigate the overall prevalence of cardiovascular disease (CVD in subjects hospitalized for chronic obstructive pulmonary disease (COPD, and explore the prevalence of the major CVD complications and trends in patients with COPD over a 10-year period. Methods Medical records in the PLA General Hospital, Beijing Union Medical College Hospital, and Beijing Hospital from 2000/01/01 to 2010/03/03 were retrospectively reviewed. A total of 4960 patients with COPD were reviewed in the study (3570 males, mean age, 72.2 ± 10.5 years; 1390 females, mean age, 72.0 ± 10.4 years. Results The prevalence of CVD in COPD patients was 51.7%. The three most prevalent CVDs were ischemic heart disease (28.9%, heart failure (19.6%, and arrhythmia (12.6%. During the 10-year study period, the prevalence of various CVDs in COPD patients showed a gradual increasing trend with increasing age. There was higher morbidity due to ischemic heart disease (P < 0.01 in male COPD patients than in the female counterparts. However, heart failure (P < 0.01 and hypertension (P < 0.01 occurred less frequently in male COPD patients than in female COPD patients. Furthermore, the prevalence of ischemic heart disease decreased year by year. In addition to heart failure, various types of CVD complications in COPD patients tended to occur in younger subjects. The prevalence of all major types of CVD in women tended to increase year by year. Conclusions The prevalence of CVD in patients hospitalized for COPD in Beijing was high. Age, sex and CVD trends, as well as life style changes, should be considered when prevention and control strategies are formulated.

    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 Objective: This study aimed to develop a drug cost model for injuries due to road traffic accidents for patients receiving treatment at a regional hospital in Thailand. Methods: The study was designed as a retrospective, descriptive analysis. The cases were all from road traffic accidents receiving treatment at a public regional hospital in the fiscal year 2004. Results: Three thousand seven hundred and twenty-three road accident patients were included in the study. The mean drug cost per case was USD18.20 (SD=73.49, median=2.36. The fitted drug cost model had an adjusted R2 of 0.449. The positive significant predictor variables of drug costs were prolonged length of stay, age over 30 years old, male, Universal Health Coverage Scheme, time of accident during 18:00-24:00 o’clock, and motorcycle comparing to bus. To forecast the drug budget for 2006, there were two approaches identified, the mean drug cost and the predicted average drug cost. The predicted average drug cost was calculated based on the forecasted values of statistically significant (p<0.05 predictor variables included in the fitted model; predicted total drug cost was USD44,334. Alternatively, based on the mean cost, predicted total drug cost in 2006 was USD63,408. This was 43% higher than the figure based on the predicted cost approach.Conclusions: The planned budget of drug cost based on the mean cost and predicted average cost were meaningfully different. The application of a predicted average cost model could result in a more accurate budget planning than that of a mean statistic approach.

    2014-01-01

    Background: In cities with trams as public transportation, tram tracks are often on public roads, creating a shared road situation with other road participants like cyclists. Beside the risk of direct collisions, this situation can also lead to bicycle wheels getting wedged in tram tracks, causing cyclists to fall. Objectives: The aim of this study was to gain more insight in the injury pattern of this trauma mechanism and to draw attention to the risks of the infrastructural situation with on-road tram tracks. Patients and Methods: A one-year, prospective, observational cohort study was conducted. All patients admitted after presentation to the emergency department of a level 1 trauma center, who got injured because their bicycle wheels got wedged in tram tracks, were included. Data were collected on patient demographics, type of injury and treatment. Results: Ten patients were included. Six were male. The mean age was 38 years. Six patients required surgery, mostly because of extremity injuries. Mean duration of admission was 4 days. Mean injury severity score was 13. One patient died as a result of the injuries sustained in the accident. Conclusions: Tram tracks on public roads are potentially dangerous and can lead to serious injuries and even mortality amongst cyclist. Operative intervention is frequently needed. PMID:25685751

    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.

    2007-01-01

    Full Text Available Background: Traumatic airway injuries are fortunately rare. Though injuries can be obvious and initial management straightforward, the diagnosis can be difficult. We present a case of penetrating cervical tracheal injury due to ′chain snatching′ in a young female. Case Report: The young female patient presented in the Emergency Department with a bleeding neck wound. Orotracheal intubation was done after resuscitation, revealing a transected trachea. There was no injury to major vessels or nerves, so the wound was debrided and closed in layers and a tracheostomy tube was placed through the transected trachea. Postoperatively, the patient was ventilated for 72h, after which she completely recovered. Discussion: Initial management can be complicated by associated head, neck and thoracic injuries. Orotracheal intubation or tracheostomy through the tracheal wound is the ideal way to manage these cases. Surgical repair of the trachea is not always necessary. Mortality rates and the incidence of late complications remain high and have been related to delays in diagnosis and definitive treatment.

    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. PMID:25882144

    Full Text Available We describe a case of delayed presentation of attempted suicide with a nail gun that penetrated both the right and left ventricle. Nearly invisible entry point of the nail did not reflect the gravity of the injury. A prompt and accurate history along with chest X-ray and bedside transthoracic echocardiography facilitated localization of the nails and helped assess the damage. Despite cardiac arrest after induction of general anesthesia, the patient had a successful outcome. Issues related to the injury site, modalities of investigation and management strategies in a patient with cardiac tamponade are discussed.

  14. Diffusion-weighted imaging of brain injury due to neonatal hypoglycemia: a case report

    International Nuclear Information System (INIS)

    Profound hypoglycemia results in significant brain injury because glucose is essential for normal brain functioning. We present here a case of transient neonatal hypoglycemia with diffuse brain injury. Magnetic resonance imaging was performed 2 days after onset, and this revealed bilateral regions of restricted diffusion in the parietal, occipital, frontal and temporal lobes. On the T1-weighted images, the regions showed indistinct gray matter-white matter differentiation. There were subtle high signal intensity lesions along the corresponding regions of the FLAIR and T2-weighted images

    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.

    Aim: The overexpression of the human tissue kallikrein (HK) gene can reduce blood pressure and ameliorate the secondary syndromes associated with hyper- tension in animal models. The current study was designed to investigate hy- potensive effect of intramuscular delivery of HK gene. Methods: We generated an recombinant adeno-associated virus (rAAV) vector expressing human tissue kallikrein under the control of a cytomegalovirus promoter and administered the rAAV-HK vector to a spontaneously hypertensive rat model at a dose of 1× 1010 virons/rat through intramuscular injection. Results: A persistent, high-level ex- pression of HK post-gene delivery was confirmed by ELISA. The systolic blood pressure in the rats receiving rAAV-LacZ and saline increased from 171.3 mmHg to 182.3 mmHg 28 weeks' post injection. In contrast, the delivery of the HK gene by AAV vectors attenuated the increase of the systolic blood pressure in the treated group. The systolic blood pressure was only slightly lowered (from a level of 174 mmHg to 170.5 mmHg) post-vector administration. The difference in blood pres- sure between the treated group and the control groups is statistically significant at 12.6 mmHg. The hypotensive effect of rAAV-HK persisted until the end of the testing period. In addition, a significant amelioration of cardiovascular hypertrophy, renal injury, and collagen depositions in the rAAV-HK-treated ani- mals were also observed. Conclusion: All the effects are comparable with those of intravenous delivery. Therefore, the intramuscular administration of rAAV-HK may be used in gene therapy for hypertension.

    Ischemia/reperfusion injury (IRI) contributes to morbidity and mortality after cardiovascular surgery requiring cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA). Multi-organ damage is associated with substantial decreases of blood selenium (Se) levels in patients undergoing cardiac surgery with CPB. We compared the influence of a dietary surplus of Se and pretreatment with ebselen, a mimic of the selenoenzyme glutathione peroxidase, on IRI-induced tissue damage and inflammation. Male Wistar rats were fed either a Se-adequate diet containing 0.3 ppm Se or supplemented with 1 ppm Se (as sodium selenite) for 5 weeks. Two other groups of Se-adequate rats received intraperitoneal injection of ebselen (30 mg/kg) or DMSO (solvent control) before surgery. The animals were connected to a heart-lung-machine and underwent 45 min of global ischemia during circulatory arrest at 16 °C, followed by re-warming and reperfusion. Selenite and ebselen suppressed IRI-induced leukocytosis and the increase in plasma levels of tissue damage markers (AST, ALT, LDH, troponin) during surgery but did not prevent the induction of proinflammatory cytokines (IL-6, TNF-α). Both Se compounds affected phosphorylation and expression of proteins related to stress response and inflammation: Ebselen increased phosphorylation of STAT3 transcription factor in the heart and decreased phosphorylation of ERK1/2 MAP kinases in the lungs. Selenite decreased ERK1/2 phosphorylation and HSP-70 expression in the heart. Pretreatment with selenite or ebselen protected against acute IRI-induced tissue damage during CPB and DHCA. Potential implications of their different actions with regard to molecular stress markers on the recovery after surgery represent promising targets for further investigation. PMID:27192987

    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.

    Fatty liver disease (FLD) is the most prevalent form of liver disease worldwide. Overnutrition can induce nonalcoholic fatty liver disease (NAFLD), a spectrum of conditions ranging from simple steatosis [or nonalcoholic fatty liver (NAFL)] to nonalcoholic steatohepatitis and cirrhosis. Some of the epidemiological and pathological studies have also suggested an association between the presence of fatty liver and sudden death. A 37-year-old man was found dead when he was asleep in the bed at home. According to his family, he was single and a costermonger. He was not an athlete, and there was no history of any physical and mental disorder. He was not addicted and did not use any drugs or alcohol. The positive points, in this case, were: a large heart with mild coronary stenosis and steatohepatitis in autopsy and sudden death. Since steatohepatitis did not have any complication such as fat embolism, it can be concluded that the combination of steatohepatitis and cardiovascular disorder led to sudden unexpected death. Heart more than 450 gr is susceptible to arrhythmia, and fatty liver disease can cause cardiovascular changes. PMID:27309272

    Mild elevations in core temperature can occur in individuals involved in strenuous activities that are risky for potentially sustaining a mild traumatic brain injury (mTBI) or concussion. Recently, we have discovered that mild elevations in brain temperature can significantly aggravate the histopathological consequences of mTBI. However, whether this exacerbation of brain pathology translates into behavioral deficits is unknown. Therefore, we investigated the behavioral consequences of elevating brain temperature to mildly hyperthermic levels prior to mTBI. Adult male Sprague Dawley rats underwent mild fluid-percussion brain injury or sham surgery while normothermic (37 °C) or hyperthermic (39 °C) and were allowed to recover for 7 days. Animals were then assessed for cognition using the water maze and cue and contextual fear conditioning. We found that mTBI alone at normothermia had no effect on long-term cognitive measures whereas mTBI animals that were hyperthermic for 15 min prior to and for 4h after brain injury were significantly impaired on long-term retention for both the water maze and fear conditioning. In contrast, hyperthermic mTBI animals cooled within 15 min to normothermia demonstrated no significant long-term cognitive deficits. Mild TBI irrespective of temperature manipulations resulted in significant short-term working memory deficits. Cortical atrophy and contusions were detected in all mTBI treatment groups and contusion volume was significantly less in hyperthermic mTBI animals that were cooled as compared to hyperthermic mTBI animals that remained hyperthermic. These results indicate that brain temperature is an important variable for mTBI outcome and that mildly elevated temperatures at the time of injury result in persistent cognitive deficits. Importantly, cooling to normothermia after mTBI prevents the development of long-term cognitive deficits caused by hyperthermia. Reducing temperature to normothermic levels soon after mTBI represents

  16. Erythrocyte Aggregation due to Surface Nanobubble Interactions During the Onset of Thermal Burn Injury

    Science.gov (United States)

    Seidner, Harrison S.

    Red Blood Cell (RBC) aggregation is an important hemorheological phenomenon especially in microcirculation. In healthy individuals, RBCs are known to aggregate and gravitate toward the faster flow in the center of vessels to increase their throughput for more efficient oxygen delivery. Their aggregation is known to occur during a variety of environmental, pathological, and physiological conditions and is reversible when aggregates are subject to the relatively high shear forces in the circulation. The likelihood that aggregates will monodisperse in flow is dependent on the conditions during which they form. In situations where such aggregates are not sheared to monodispersion their presence can impact the perfusion of microvascular networks. More specifically, aggregates subject to the low shear rates in the zone of stasis near regions of thermal burn injury are capable of occluding vessels in the microcirculation and inhibiting the delivery of oxygen and nutrients to tissue downstream. The basic mechanism leading to erythrocyte aggregation at the onset of thermal injury is unknown. This dissertation investigates parameters involved in erythrocyte aggregation, methods of measuring and testing erythrocyte aggregation, and incorporates modeling based on first principles ultimately to propose a mechanism of this phenomenon.

    Full Text Available Human civilization in all phases of its development has been accompanied by different kinds of fear related to disease, death, injury, separation, pain, loneliness, darkness, imagined creatures, natural appearances etc. Fear has become a constant part of human life and it has always required appropriate mechanisms for defense. It is very important to be mentioned that fears occur with children as well. Fears acquire specific form with physically disabled, ill children and children with poor health etc.A great number of authors explain children’s fears from many aspects connected with the factor and manifestations of certain forms of children’s fear.In that sense, it is pointed out that the reasons for children’s fears can be divided in three categories: innate, endured and imagined.Fear, both with adults and children, is accompanied by concrete physiological processes mainly of biochemical and functional nature.

  19. Long term outcome of acute kidney injury due to leptospirosis? A longitudinal study in Sri Lanka

    Science.gov (United States)

    2014-01-01

    Background Leptospirosis is an important zoonotic disease of variable severity and is a common cause of acute kidney injury (AKI) in tropics. However the knowledge on long term renal outcome in leptospirosis is scarce. This study aims to assess the long-term renal outcome of AKI caused by leptospirosis. Findings Hospital records of patients who had developed AKI following leptospirosis (Serologically confirmed) presented to two Teaching Hospitals in Kandy district over 3 years from 2007 were studied. A total of 44 patients were included and they had been followed up at least for one year in out patient clinics with regular assessment including renal status. Renal histology was studied in two patients. The primary outcome measure was normalization of renal function at one year. Of the 44 patients, 31 were in the risk and injury stage (Group 1), and the rest of them were in the failure stage (Group 2) under RIFLE criteria. Of group 2 patients, 11 had abnormal renal functions on discharge. Their mean serum creatinine and GFR values on discharge were 392 mmol/l and 20 ml/min/1.73 m2. Other two patients had full renal recovery whilst in the hospital. Nine in the group 2 required renal replacement therapy by means of peritoneal dialysis, intermittent haemodialysis or haemofiltration. Seventeen out of the total had persistently abnormal renal functions on discharge. Of them 13 recovered their renal functions to normal. Four patients (9%) who belonged to group 2, had persistently abnormal renal functions after first year compatible with stage 3 chronic kidney disease (CKD). Renal histology of two patients showed tubulointerstitial lymphocyte infiltrate, tubular atrophy and interstitial fibrosis. Conclusion The long term renal outcome of AKI following leptospirosis is satisfactory as only 9% of patients had abnormal renal functions compatible with early stage of CKD. Even among them, advanced CKD or dialysis dependency had not been observed. PMID:24964804

    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.

    Full Text Available We report a case requiring biliary reconstruction with right hepatic lobectomy due to biliary strictures caused by continuous cholangitis after laparoscopic bile duct injury. The patient, a 55-year-old woman, underwent laparoscopic cholecystectomy for cholelithiasis at another hospital. Although a bile leakage from the intraabdominal drain was observed several days after the operation, the patient was not given adequate treatment to stop the leakage. Two months after the initial laparoscopic cholecystectomy, she was referred to our hospital. Endoscopic retrograde cholangiopancreatography (ERCP showed complete obstruction of the common hepatic duct, which was caused by clipping during laparoscopic cholecystectomy. Cholangiography from percutaneous transhepatic biliary drainage (PTBD catheters revealed that sections of the secondary branches of the right intrahepatic bile duct had become constricted due to persistent cholangitis. Fortunately, the left hepatic duct was judged to be normal by imaging. Therefore, we elected to perform a right hepatic lobectomy and left hepaticojejunostomy, because we felt that performing a hepaticojejunostomy without hepatic resection would put the patient at risk of continuing to suffer from cholangitis. The patient was discharged on the 55 th postoperative day, and, 5 years after reconstructive surgery, is healthy and has remained free from biliary strictures in the remnant liver. Appropriate decision-making is essential in the treatment of biliary injury after laparoscopic cholecystectomy. Surgeons should not hesitate to perform biliary reconstruction with hepatic resection to reduce the risk of cholangitis or biliary strictures of the remnant liver. More importantly, preoperative clear imaging of the biliary tree and suitable management of any biliary injury which might occur are necessary to avoid having to perform reconstructive surgery.

    Full Text Available Abstract Background Lower limb paralysis occurs in 11% of patients after surgical procedure of thoracic or thoracoabdominal aneurysms and is an unpredictable and distressful complication. The aim of this study was to investigate the effects of tetramethylpyrazine (TMP, an intravenous drug made from traditional Chinese herbs, on the neurologic outcome and hisotpathology after transient spinal cord ischemia in rabbits. Methods Forty-five male New Zealand white rabbits were anesthetized with isoflurane and spinal cord ischemia was induced for 20 min by infrarenal aortic occlusion. Animals were randomly allocated to one of five groups (n = 8 each. Group C received no pharmacologic intervention. Group P received intravenous infusion of 30 mg·kg-1 TMP within 30 min before aortic occlusion. Group T1, Group T2 and Group T3 received intravenous infusion of 15, 30 and 60 mg·kg-1 TMP respectively within 30 min after reperfusion. In the sham group (n = 5, the animals underwent the same procedures as the control group except infrarental aortic unocclusion. Neurologic status was scored by using the Tarlov criteria (in which 4 is normal and 0 is paraplegia at 4 h, 8 h, 12 h, 24 h, and 48 h after reperfusion. All animals were sacrificed at 48 h after reperfusion and the spinal cords (L5 were removed immediately for histopathologic study. Results All animals in the control group became paraplegic. Neurologic status and histopathology (48 h in the Groups P, T2 and T3 were significantly better than those in the control group (P r = 0.776, P Conclusion Tetramethylpyrazine significantly reduces neurologic injury related to spinal cord ischemia and reperfusion after aortic occlusion within a certain range of dose.

  3. Association between micronuclei frequency in pollen mother cells of Tradescantia and mortality due to cancer and cardiovascular diseases: A preliminary study in Sao Jose dos Campos, Brazil

    International Nuclear Information System (INIS)

    The present study was designed to explore the correlation between the frequency of micronuclei in Trad-MN, measured across 28 biomonitoring stations during the period comprised between 11 of May and 2 of October, 2006, and adjusted mortality rates due to cardiovascular, respiratory diseases and cancer in Sao Jose dos Campos, Brazil, an area with different sources of air pollution. For controlling purposes, mortality rate due to gastrointestinal diseases (an event less prone to be affected by air pollution) was also considered in the analysis. Spatial distribution of micronuclei frequency was determined using average interpolation. The association between health estimators and micronuclei frequency was determined by measures of Pearson's correlation. Higher frequencies of micronuclei were detected in areas with high traffic and close to a petrochemical pole. Significant associations were detected between micronuclei frequency and adjusted mortality rate due to cardiovascular diseases (r = 0.841, p = 0.036) and cancer (r = 0.890, p = 0.018). The association between mortality due to chronic obstructive pulmonary diseases was positive but did not reach statistical significance (r = 0.640, p = 0.172), probably because of the small number of events. Gastrointestinal mortality did not exhibit significant association with micronuclei frequency. Because the small number of observations and the nature of an ecological study, the present findings must be considered with caution and considered as preliminary. Further studies, performed in different conditions of contamination and climate should be done before considering Trad-MN in the evaluation of human health risk imposed by air pollutants. - Bioassay used to explore the correlation between air pollution exposition and mortality rates.

    Background: The role imaging studies play in the choice of treatment in traumatic pancreas damage remains unclear. This study was performed to gain insight into the role of radiological studies in children 16 years of age or younger admitted to our hospital with pancreatic damage due to a blunt abdominal trauma. Method: Retrospectively, the radiological as well as patient clinical records were reviewed of all children admitted to our hospital between 1975 and 2003 with a pancreatic lesion due to blunt abdominal trauma. Results: Thirty-four children with ages ranging from 3 to 14 years old were admitted with traumatic pancreas damage. Initially 33 children were treated conservatively for the pancreatic damage and only one had immediate surgery of the pancreas with a Roux-y pancreaticojejunostomy. Five other children had immediate surgery for other reasons. Overall, five children proved to have a pancreas transection on CT scans or during laparotomy. One child had a pancreas hematoma and 28 a pancreas contusion. In total 15 children developed a pseudocyst (44%), nine of which resolved spontaneously while six were treated by intervention. None of the children had residual morbidity, and there were no deaths. Considering the pancreas, the 11 available CT's were re-evaluated by two radiologists independently. Grade 3 pancreas damage (distal transection of the pancreatic duct) was diagnosed in five patients by radiologist A and four patients by radiologist B (80% match); Grade 1 was diagnosed in, respectively six and one patients (15% match). An US was performed on 19 children with 82 follow-up examinations, mostly for follow-up of the pseudocysts. Conclusion: Traumatic pancreas damage is a rare and difficult diagnosis. There is no straightforward answer for diagnostic imaging in blunt abdominal trauma in children. The diagnostic relevance of CT is limited. CT in combination with MRCP may be a better option for exclusion of pancreatic duct lesions.

    Full Text Available Background: We evaluated the efficacy of botulinum-A toxin (BTX-A injection into detrusor muscle in patients with incontinence resistant to anticholinergic drugs due to detrusor overactivity.Methods: Our prospective study included 12 male patients with detrusor overactivity and incontinence due to spinal cord injury, which had been unsuccessfully treated with anticholinergic medication. Under visual control through the cystoscope 300 units of BTX-A were injected into detrusor muscle at 30 sites, sparing the trigone. After the treatment patients continued to perform clean intermittent self-catheterization (CIC and clinical follow-up was planned for 6 weeks, 6 months and 9 months after treatment and urodynamic study was repeated after 6 weeks.Results: At the 6-week follow-up complete continence was restored in  9 of the 12 patients and after 6 months of 9 continent patients 1 patient lost his follow-up  from the study and 7 were still continent. After 9 months 3 patients remained continent. Mean cystometric bladder capacity (p<0.001, compliance (p<0.001, and mean post-void residual urine volume significantly increased (p<0.001, whereas maximal detrusor contraction pressure significantly decreased (p<0.001.Conclusions: BTX-A injections appears to be an effective and safe therapeutic option for overactive bladder in adult patients with spinal cord injury failing anticholinergic therapy even if these patients present with very low bladder compliance. Patients may require repeated injections after 6 months to remain continent.

    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.

    2007-11-01

    Full Text Available Extrahepatic hepatic ductal injuries (EHDIs due to blunt abdominal trauma are rare. Given the rarity of these injuries and the insidious onset of symptoms, EHDI are commonly missed during the initial trauma evaluation, making their diagnosis difficult and frequently delayed. Diagnostic modalities useful in the setting of EHDI include computed tomography (CT, abdominal ultrasonography (AUS, nuclear imaging (HIDA scan, and cholangiography. Traditional options in management of EHDI include primary ductal repair with or without a T-tube, biliary-enteric anastomosis, ductal ligation, stenting, and drainage. Simple drainage and biliary decompression is often the most appropriate treatment in unstable patients. More recently, endoscopic retrograde cholangiopancreatography (ERCP allowed for diagnosis and potential treatment of these injuries via stenting and/or papillotomy. Our review of 53 cases of EHDI reported in the English-language literature has focused on the evolving role of ERCP in diagnosis and treatment of these injuries. Diagnostic and treatment algorithms incorporating ERCP have been designed to help systematize and simplify the management of EHDI. An illustrative case is reported of blunt traumatic injury involving both the extrahepatic portion of the left hepatic duct and its confluence with the right hepatic duct. This injury was successfully diagnosed and treated using ERCP.

    In this 60 patient study of sports traumatology due to football injuries, etofenamate gel proved equally effective as oral naproxen on the overall pain scores (65% none to mild pain for etofenamate versus 86% for naproxen; p greater than 0.05). The global clinical impression results have been rated as good or excellent in 44% in the naproxen group versus 50% in the etofenamate group. The incidence of side effects in the etofenamate group (3%) was lower than in the naproxen group (20%). This study demonstrates that etofenamate gel has equal efficacy as oral NSAIDS but a better side effect profile in sport injuries in football players. PMID:2094113

    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

    To histologically assess the preventive efficacy of cimetidine against scald injury on the peritoneo-serosal surface during intraperitoneal hyperthermic chemoperfusion (IHCP) for advanced gastric cancer, a randomized histologic study using cimetidine, a histamine H2-receptor antagonist, was performed for 20 patients with advanced or recurrent gastric cancer and peritoneal metastasis. Cimetidine 50 mg/kg was administered intravenously to 10 patients just prior to the IHCP (cimetidine group), and the remaining 10 patients underwent the IHCP without cimetidine (control group). The background factors and IHCP treatments of these two groups were nearly the same. Although the antitumour efficacy of the IHCP was not histologically different between the two groups, the histological analysis revealed that the peritoneo-serosal surface in the cimetidine group was protected against scald injury, compared with the control group. This finding suggests that pre-IHCP cimetidine is of great benefit for protecting the peritoneo-serosal surface from scald injury due to IHCP. PMID:9483448

  8. Observation and nursing of complications due to high re-perfusion injury occurring after balloon angioplasty for diabetic vascular diseases of lower extremity

    International Nuclear Information System (INIS)

    Objective: To evaluate the symptomatic nursing in treating the complications caused by high re-perfusion which develops after balloon angioplasty for the treatment of diabetic vascular diseases of lower extremity. Methods: Eighteen patients with lower limb ischemia caused by diabetes mellitus developed high re-perfusion injury complications after receiving balloon angioplasty. The patients were randomly and equally divided into study group and control group. The special nursing measures designed by the author's department, including raising the diseased lower limb, enforcing the flexion and extension movement of the leg, cold compress, wound exposure, etc. were carried out for patients of study group, while no special nursing measures were adopted for patients of control group. The clinical results, such as limb pain, swelling and subcutaneous petechia after re-perfusion injury, were evaluated and compared between two groups. Results: After the treatment, the limb pain, swelling and subcutaneous petechia due to high re-perfusion injury in study group were relieved more markedly than that in control group, the difference in evaluation score between two groups was statistically significant (P<0.01). Conclusion: The special symptomatic nursing measures are very effective in relieving the high re-perfusion injury after balloon angioplasty for the treatment of diabetic lower limb ischemia.

    2014-01-01

    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.

    2015-10-01

    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.

    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.

    Full Text Available Autonomic dysreflexia is a hypertensive clinical emergency for persons with spinal cord injury at T-6 level or above. Recurrent autonomic dysreflexia is uncommon in spinal cord injury patients and is usually caused by noxious stimuli that cannot be removed promptly, e.g., somatic pain, abdominal distension. A 61-year-old man, who sustained tetraplegia at C-5 (ASIA-A 38 years ago, was admitted with chest infection. Computerised tomography (CT of the chest showed the ascending aorta to measure 4 cm in anteroposterior diameter; descending thoracic aorta measured 3.5 cm. No dissection was seen. Normal appearances of abdominal aorta were seen. He was treated with noninvasive ventilation, antibiotics, and diuretics. Nineteen days later, when there was sudden deterioration in his clinical condition, CT of the pulmonary angiogram was performed to rule out pulmonary embolism. This showed no pulmonary embolus, but the upper abdominal aorta showed some dissection with thrombosis of the false lumen. Blood pressure was controlled with perindopril 2 mg, once a day, doxazosin 4 mg, twice a day, and furosemide 20 mg, twice a day. Since this patient did not show clinical features of mesenteric or lower limb ischaemia, the vascular surgeon did not recommend subdiaphragmatic aortic replacement.

  14. Static magnetic field effect on the arterial baroreflex-mediated control of microcirculation: implications for cardiovascular effects due to environmental magnetic fields.

    Gmitrov, Juraj

    2007-08-01

    Increasing evidence suggests that time-varying and static magnetic fields in the environment might affect the cardiovascular system. To explore the underlying physiology, the effect of static magnetic fields (SMFs) on the carotid baroreflex control of microcirculation was studied. Twenty-four hemodynamic monitorings were performed in rabbits sedated by pentobarbital infusion (5 mg/kg/h) during experiments that lasted 120 min. Mean femoral artery blood pressure, heart rate, and ear lobe skin microcirculatory blood flow, measured by microphotoelectric plethysmogram (MPPG), were simultaneously recorded before and after a 40 min exposure of the sinocarotid baroreceptors to Nd(2)-Fe(14)-B alloy magnets (n = 14) or sham magnets (n = 10, control series). The local SMF field was 350 mT, at the baroreceptors' site. Arterial baroreflex sensitivity (BRS) was estimated from heart rate/blood pressure response to intravenous bolus injections of nitroprusside and phenylephrine. A significant positive correlation was found between the SMF-induced increase in BRS (DeltaBRS = BRS(afterSMF) - BRS(priorSMF)) and the increment in microvascular blood flow (DeltaMPPG = MPPG(afterSMF) - MPPG(priorSMF)) (r = 0.66, p < 0.009). The SMF probably modulated the arterial baroreflex-mediated microcirculatory control. This could represent one possible mechanism how environmental magnetic fields act on the cardiovascular system, and a method how to complexly adjust macro- and microcirculation with potential clinical implementation.

    This study aims to investigate the acute protective effect of montelukast sodium in hepatic injury secondary to acetaminophen (APAP) intoxication. This study used 60 rats. The rats were grouped into 6 groups. The control group was administered oral distilled water 10 ml/kg, the APAP group oral APAP 1 g/kg, the montelukast sodium (MK) group oral MK 30 mg/kg, the acetaminophen+N-acetylcysteine (APAP+NAC) group oral APAP 1 g/kg, followed by a single dose of intraperitoneal NAC 1.5 g/kg three hours later, the acetaminophen+montelukast sodium (APAP+MK) group oral APAP 1 g/kg, followed by oral MK 30 mg/kg 3 h later, the acetaminophen+N-acetylcysteine+montelukast sodium (APAP+NAC+MK) group oral APAP 1 g/kg, followed by a single intraperitoneal NAC 1.5 g/kg plus oral MK 30 mg/kg 3 h later. Blood and liver tissue samples were taken 24h after drug administration. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin were studied from the blood samples. Liver tissue samples were used for histopathological examination. Compared with the control group, serum AST and ALT activities were higher in the APAP and APAP+NAC groups. APAP+NAC, APAP+MK, and APAP+NAC+MK groups had reduced serum ALT and AST activities than the group administered APAP alone. APAP+MK and APAP+NAC+MK groups had a lower serum ALP activity than the control group. Histopathologically, there was a difference between the group administered APAP alone and the APAP+MK and APAP+NAC+MK groups. MK is as protective as NAC in liver tissue in APAP intoxication in rats.

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

    Directory of Open Access Journals (Sweden)

    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

    2013-01-01

    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

    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. PMID:26837110

  2. F-18-fluoride PET for early diagnosis and evaluation of therapeutic outcome in patients with heterotopic ossification (HO) after recent paraplegia due to spinal cord injury

    International Nuclear Information System (INIS)

    Aim: Heterotopic ossification (HO) is the presence of bone in soft tissue. The acquired form of HO most frequently is seen with either musculoskeletal trauma, spinal cord injury or central nervous system injury. Fever, swelling, erythema, and occasional joint tenderness seen in early HO can be difficult to distinguish from cellulitis, osteomyelitis or thrombophlebitis. As compared to paraplegia alone, combination of HO and paraplegia, especially excessive delay of diagnosis, is associated with a significantly higher incidence for thrombosis, immobilization, decubitus leading to a reduced expectation and quality of life. To evaluate the role of F-18-fluoride PET for the early diagnosis and the evaluation of the therapeutic outcome, 38 patients (56 PET examinations) were analyzed prospectively. Material and Methods: Within 8 weeks after acquired paraplegia, each patient was studied by F-18-fluoride PET in addition to clinical, serologic and conventional radiographic examinations. Whole-body PET studies (ECAT Exact 47, attenuation corrected, iterative reconstruction) were obtained 150 min. after injection of 12 MBq F-18-fluoride/kg body weight. For semi-quantitative analysis, standardized-uptake values (SUV) and the metabolic transverse diameters (MTD) of the lesions were assessed. To prevent post-traumatic neurogenic HO, patients received physiotherapy and NSA (indomethacin 3 x 50 mg per day for 4 months). In addition, external beam radiation therapy (EBRT, 1x7 Gy according to ICRU) was administered, if PET demonstrated HO. Therapeutic outcome was compared with a historical group of patients receiving only physiotherapy. Kaplan-Meier-Method, log-rank-, chi-square- and Wilcoxon-test were used for statistical analyses. Results: In the course of HO, 4/38 patients received EBRT with 1x7 Gy for a second time due to an increasing SUV and/or MTD and rising levels of alkaline phosphatase. Within a follow-up period of at least 30 months, none of the patients showed clinical

    2006-09-01

    Full Text Available Abstract Background Epidural anaesthesia is used extensively for cardiothoracic and vascular surgery in some centres, but not in others, with argument over the safety of the technique in patients who are usually extensively anticoagulated before, during, and after surgery. The principle concern is bleeding in the epidural space, leading to transient or persistent neurological problems. Methods We performed an extensive systematic review to find published cohorts of use of epidural catheters during vascular, cardiac, and thoracic surgery, using electronic searching, hand searching, and reference lists of retrieved articles. Results Twelve studies included 14,105 patients, of whom 5,026 (36% had vascular surgery, 4,971 (35% cardiac surgery, and 4,108 (29% thoracic surgery. There were no cases of epidural haematoma, giving maximum risks following epidural anaesthesia in cardiac, thoracic, and vascular surgery of 1 in 1,700, 1 in 1,400 and 1 in 1,700 respectively. In all these surgery types combined the maximum expected rate would be 1 in 4,700. In all these patients combined there were eight cases of transient neurological injury, a rate of 1 in 1,700 (95% confidence interval 1 in 3,300 to 1 in 850. There were no cases of persistent neurological injury (maximum expected rate 1 in 4,600. Conclusion These estimates for cardiothoracic epidural anaesthesia should be the worst case. Limitations are inadequate denominators for different types of surgery in anticoagulated cardiothoracic or vascular patients more at risk of bleeding.

    Penetrating cardiac injury tends to generally be repaired without cardiopulmonary bypass in the operating room. We herein report the case of penetrating cardiac injury repaired using percutaneous cardiopulmonary support in an emergency room. A 57-year-old man attempted suicide by stabbing himself in the left anterior chest with a knife. Although the patient suffered cardiopulmonary arrest for 7 min in the ambulance, spontaneous circulation was restored following pericardiotomy through emergency left thoracotomy in the emergency room. To prevent coronary artery injury and control the massive bleeding, percutaneous cardiopulmonary support was instituted without systemic heparinization and the cardiac injury was repaired in the emergency room. The patient was then transferred to another hospital on day 46 for further rehabilitation. Percutaneous cardiopulmonary support might be helpful for treating critical patients in an emergency room, even in the case of trauma patients. PMID:17342366

    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.

  10. Topographic Locomotive Analysis of 99mTc-HDP Uptake of Acute Rhabdomyolysis and Musculotendinous Unit Injury due to Excessive Swimming Exercise in Novice: A Case Report

    International Nuclear Information System (INIS)

    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 9:9mTc-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 99mTc-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

    Background. Acute kidney injury (AKI) treated with continuous renal replacement therapy (CRRT) is a severe complication in trauma patients. The aim of the study was to assess primary traumatic injuries and secondary organ failures in severe posttraumatic AKI. Methods. Retrospective review of adult trauma patients admitted to the trauma centre at Oslo University Hospital Ullevål. Injury severity score (ISS) was used to assess the severity of primary injuries, and sequential organ failure assessment (SOFA) score was utilized to measure secondary organ failures. Results. Forty-two (8%) of 506 trauma patients admitted to intensive care unit developed AKI treated with CRRT, whereof 40 (95%) suffered blunt trauma mechanisms. Patients had extensive primary organ injuries with median (interquartile range) ISS 36 (27-49). The majority of the patients had respiratory (93% intubated) and cardiovascular (67% with inotropic and/or vasoactive medication) failure within 24 hours after admission. AKI was often part of multiple organ failure, most frequently respiratory and cardiovascular failure, affecting 33 (75%) and 30 (71%) of the patients, respectively. Conclusion. Trauma patients with AKI undergoing CRRT often had severe primary injuries due to blunt trauma. Most of them suffered from secondary multiple organ failure concomitant to AKI. PMID:25587490

    2014-01-01

    The cardiovascular sequelae of radiation exposure are an important cause of morbidity and mortality following radiation therapy for cancer, as well as after exposure to radiation after atomic bombs or nuclear accidents. In the United States, most of the data on radiation-induced heart disease (RIHD) come from patients treated with radiation therapy for Hodgkin disease and breast cancer. Additionally, people exposed to radiation from the atomic bombs in Hiroshima and Nagasaki, Japan, and the Chernobyl, Ukraine, nuclear accident have an increased risk of cardiovascular disease. The total dose of radiation, as well as the fractionation of the dose, plays an important role in the development of RIHD. All parts of the heart are affected, including the pericardium, vasculature, myocardium, valves, and conduction system. The mechanism of injury is complex, but one major mechanism is injury to endothelium in both the microvasculature and coronary arteries. This likely also contributes to damage and fibrosis within the myocardium. Additionally, various inflammatory and profibrotic cytokines contribute to injury. Diagnosis and treatment are not significantly different from those for conventional cardiovascular disease; however, screening for heart disease and lifelong cardiology follow-up is essential in patients with past radiation exposure.

    Full Text Available Rakesh K Sharma, Donald J Voelker, Roma Sharma, Hanumanth K ReddyUniversity of Arkansas for Medical Sciences, Medical Center of South Arkansas, El Dorado, AR, USAAbstract: Throughout their lifetime, an individual may sustain many injuries and recover spontaneously over a period of time, without even realizing the injury in the first place. 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

    1989-01-01

    As a starting point, the group defined a primary goal of maintaining in flight a level of systemic oxygen transport capacity comparable to each individual's preflight upright baseline. The goal of maintaining capacity at preflight levels would seem to be a reasonable objective for several different reasons, including the maintenance of good health in general and the preservation of sufficient cardiovascular reserve capacity to meet operational demands. It is also important not to introduce confounding variables in whatever other physiological studies are being performed. A change in the level of fitness is likely to be a significant confounding variable in the study of many organ systems. The principal component of the in-flight cardiovascular exercise program should be large-muscle activity such as treadmill exercise. It is desirable that at least one session per week be monitored to assure maintenance of proper functional levels and to provide guidance for any adjustments of the exercise prescription. Appropriate measurements include evaluation of the heart-rate/workload or the heart-rate/oxygen-uptake relationship. Respiratory gas analysis is helpful by providing better opportunities to document relative workload levels from analysis of the interrelationships among VO2, VCO2, and ventilation. The committee felt that there is no clear evidence that any particular in-flight exercise regimen is protective against orthostatic hypotension during the early readaptation phase. Some group members suggested that maintenance of the lower body muscle mass and muscle tone may be helpful. There is also evidence that late in-flight interventions to reexpand blood volume to preflight levels are helpful in preventing or minimizing postflight orthostatic hypotension.

    International Nuclear Information System (INIS)

    To assess the Mustard gas exposure effects on pulmonary system, particularly on diffusing capacity for lung carbon monoxide (DLCO) and simple spirometry. Sixty-five sulfur mustard- poisoned soldiers from Mostazafan and Janbazan organization were referred to our center in 2005. Complete history, physical examination, chest X ray, Echocardiography, Arterial blood gas, high - resolution computerized tomography, diffusion capacity for lung carbon monoxide and spirometry of these were performed and compared this result with normal value. The mean value of indices in studied injured subjects was: Spirometry: forced expiratory volume in one second (FEV1) = 70.4, Forced vital capacity (FVC) = 66.5, EFE 25-75=81.1, FEV1/FVC=101.9, Flow 25% = 28.7, Flow 50%= 72.9, Flow 75%= 100.1, Sample volume: Functional residual capacity of lungs (FRC) = 131.5, residual volume (RV) = 157.3, RV/TLC= 169.1, Total lung capacity (TLC) = 91.3, KCO= 131.6, TLCO= 116.3. No significant correlation was observed between TLCO values with HRCT, echocardiography, ABG and spirometry values (P>0.05). We recommend TLCO and RV/TLV tests to assess severity of Injuries as there is no a suitable criterion to measure the real consequences of mustard gas on affected combatants. and Biological markers are also needed to determine cause effect relations.

    Full Text Available Blunt injuries to the anterior neck are most commonly due to road traffic accidents but the incidence of such types of injuries are decreasing probably due to stricter laws pertaining to seat belts and drunken driving. 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. The mechanism of injury was probably a combination of penetrating and blunt trauma neck. This case highlights the mechanism of laryngeal injury, its presentation and management

    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.

    Type 2 diabetes is characterized by a high risk of micro- and macro-vascular complications. Cardiovascular diseases are the leading cause of death of diabetic patients. In this context, the search for molecules decreasing cardiovascular mortality makes sense. Until the EMPA-REG OUTCOME study published late 2015, showing a reduction of cardiovascular mortality of patients treated with empagliflozin, an SGLT2 inhibitor, there was no molecule known to decrease cardiovascular mortality. The purpose of this article is to review the various existing antidiabetic molecules and their impact (positive/neutral/negative) on cardiovascular mortality. PMID:27487675

    The ubiquitin proteasome system (UPS) plays a crucial role in biological processes integral to the development of the cardiovascular system and cardiovascular diseases. The UPS prototypically recognizes specific protein substrates and places polyubiquitin chains on them for subsequent destruction by the proteasome. This system is in place to degrade not only misfolded and damaged proteins, but is essential also in regulating a host of cell signaling pathways involved in proliferation, adaptation to stress, regulation of cell size, and cell death. During the development of the cardiovascular system, the UPS regulates cell signaling by modifying transcription factors, receptors, and structural proteins. Later, in the event of cardiovascular diseases as diverse as atherosclerosis, cardiac hypertrophy, and ischemia/reperfusion injury, ubiquitin ligases and the proteasome are implicated in protecting and exacerbating clinical outcomes. However, when misfolded and damaged proteins are ubiquitinated by the UPS, their destruction by the proteasome is not always possible because of their aggregated confirmations. Recent studies have discovered how these ubiquitinated misfolded proteins can be destroyed by alternative "specific" mechanisms. The cytosolic receptors p62, NBR, and histone deacetylase 6 recognize aggregated ubiquitinated proteins and target them for autophagy in the process of "selective autophagy." Even the ubiquitination of multiple proteins within whole organelles that drive the more general macro-autophagy may be due, in part, to similar ubiquitin-driven mechanisms. In summary, the crosstalk between the UPS and autophagy highlight the pivotal and diverse roles the UPS plays in maintaining protein quality control and regulating cardiovascular development and disease.

    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. PMID:26301254

    Science.gov (United States)

    Polglase, Graeme R; Ong, Tracey; Hillman, Noah H

    2016-09-01

    The cardiovascular response to asphyxia involves redistribution of cardiac output to maintain oxygen delivery to critical organs such as the adrenal gland, heart, and brain, at the expense of other organs such as the gut, kidneys and skin. This redistribution results in reduced perfusion and localized hypoxia/ischemia in these organs, which, if severe, can result in multiorgan failure. Liver injury, coagulopathy, bleeding, thrombocytopenia, renal dysfunction, and pulmonary and gastrointestinal injury all result from hypoxia, underperfusion, or both. Current clinical therapies need to be considered together with therapeutic hypothermia and cardiovascular recovery. PMID:27524448

    Full Text Available Injuries are one of the most under-recognized public health problems facing the world today. 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].

  20. Bone stress injuries

    International Nuclear Information System (INIS)

    Bone stress injuries are due to cyclical overuse of the bone. They are relatively common in athletes and military recruits but also among otherwise healthy people who have recently started new or intensive physical activity. Diagnosis of bone stress injuries is based on the patient's history of increased physical activity and on imaging findings. The general symptom of a bone stress injury is stress-related pain. Bone stress injuries are difficult to diagnose based only on a clinical examination because the clinical symptoms may vary depending on the phase of the pathophysiological spectrum in the bone stress injury. Imaging studies are needed to ensure an early and exact diagnosis, because if the diagnosis is not delayed most bone stress injuries heal well without complications

    Objective To discuss the value of super-selective arterial embolization in treating renal hemorrhage caused by iatrogenic injuries. Methods During the period from Dec. 2009 to Feb. 2012, a total of 11 patients with renal hemorrhage caused by iatrogenic injuries were admitted to authors' hospital. The iatrogenic injuries included nephrostomy (n = 3), percutaneous nephrolithotomy(n = 3) partial nephrectomy for renal tumors (n=3) and holmium laser therapy (n = 2). By using super - selective catheterization technique, the catheter was placed into the bleeding artery, which was followed by embolization management with PVA particles, coils and/or micro-coils. Results The embolization was successfully accomplished with single manipulation in all patients. Angiography demonstrated that arteriovenous fistula, contrast extravasation and retention, the formation of pseudoaneurysm, etc. existed in diseased kidney. The hemorrhage disappeared soon after the embolization treatment and no obvious renal dysfunction was seen in all patients. During the clinical follow-up period lasting for 4 — 35 months, no recurrent hemorrhage occurred. Conclusion For the treatment of renalhemorrhage due to iatrogenic injuries, super - selective arterial embolization is safe and effective. This technique should be recommended in clinical practice.%目的 探讨超选择性动脉栓塞在医源性损伤导致的肾出血中的应用价值.方法 2009年12月至2012年2月收治11例医源性损伤导致的肾出血患者,其中肾造瘘术后出血3例,经皮肾镜取石术术后出血3例,肾肿瘤部分性肾切除术后出血3例,钬激光术后2例.采用超选择方法将导管置于出血动脉,用聚乙烯醇颗粒及弹簧圈或(和)微弹簧圈栓塞治疗.结果 所有患者均一次性成功进行出血动脉栓塞治疗,造影过程中可见动静脉瘘,对比剂外溢、滞留及假性动脉瘤形成.所有患者在栓塞治疗后出血症状均消失,未观察到明显

    2016-09-01

    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.

    For more than 15 years the A-bomb survivor studies have shown increased noncancer mortality due to radiation exposures. The most prominent cause of this increase is circulatory disease mortality. Although the estimated relative risk is less than for solid cancers (1.2 versus 1.6 per Sv), there are measurable increases in cardiovascular disease mortality at doses greater than 0.5 Sv. The evidence for circulatory diseases in mortality studies of occupational cohorts exposed to external radiation is less compelling. It is generally accepted that atherosclerosis is an inflammatory disease of the arteries and a risk factor for myocardial infarction. Immunological markers for inflammatory disease have been shown to be dose related in A-bomb survivors. Evidence from animal studies reveals increased cardiovascular mortality and arterial endothelial damage from both neutron and, to a lesser extent, gamma exposures. PMID:17119211

    Full Text Available Psoriatic arthritis (PsA is an inflammatory arthritis associated with psoriasis. In addition to skin and joint involvement, there is increasing evidence suggesting that patients with PsA also have an increase in risk of clinical and subclinical cardiovascular diseases, mostly due to accelerating atherosclerosis. Both conventional and nonconventional cardiovascular risk factors contribute to the increased cardiovascular risk in PsA. Chronic inflammation plays a pivotal role in the pathogenesis of atherosclerosis in PsA, acting independently and/or synergistically with the conventional risk factors. In this paper, we discuss the current literature indicating that patients with PsA are at risk of cardiovascular diseases.

    Lisfranc injuries are commonly asked about in FRCS Orthopaedic trauma vivas. The term "Lisfranc injury" strictly refers to an injury where one or more of the metatarsals are displaced from the tarsus. The term is more commonly used to describe an injury to the midfoot centred on the 2nd tarsometatarsal joint. The injury is named after Jacques Lisfranc de St. Martin (1790-1847), a French surgeon and gynaecologist who first described the injury in 1815. 'Lisfranc injury' encompasses a broad spectrum of injuries, which can be purely ligamentous or involve the osseous and articular structures. They are often difficult to diagnose and treat, but if not detected and appropriately managed they can cause long-term disability. This review outlines the anatomy, epidemiology, classification, investigation and current evidence on management of this injury. PMID:25543185

    Spinal cord injuries (SCI) are serious medical conditions, which are associated with severe and potentially fatal risks and complications depending on the location and extent of injury. Traffic accidents, falls and recreational activities are the leading causes for traumatic SCI (TSCI) worldwide whereas non-traumatic spinal cord injuries (NTSCI) are mostly due to tumors and congenital diseases. As chronification of the injuries progresses other organ systems are affected including anatomical changes, the respiratory and cardiovascular systems and endocrinological pathways. All these effects have to be considered in the anesthesiological management of patients with SCI. Autonomic dysreflexia (AD) is the most dangerous and life-threatening complication in patients with chronic SCI above T6 that results from an overstimulation of sympathetic reflex circuits in the upper thoracic spine and can be fatal. This article summarizes the specific pathophysiology of SCI and how AD can be avoided as well as also providing anesthetists with strategies for perioperative and intensive care management of patients with SCI.

    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. PMID:20849681

    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.

    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.

    There is a wealth of evidence linking depression to increased risk for cardiovascular disease (CVD) and worse outcomes among patients with known CVD. In addition, there are safe and effective treatments for depression. Despite this, depression remains under-recognized and undertreated in patients at risk for or living with CVD. In this review, we first summarize the evidence linking depression to increased risk of CVD and worse patient outcomes. We then review the mechanisms by which depression may contribute to cardiovascular risk and poor cardiovascular outcomes. We then summarize prior studies of depression treatment on cardiovascular outcomes. Finally, we offer guidance in the identification and management of depression among CVD populations. Given that 1 in 4 CVD patients has concurrent depression, application of these best-practices will assist providers in achieving optimal outcomes for their CVD patients. PMID:25850976

    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.

    Context Violence, experienced in either childhood or adulthood, has been associated with physical health outcomes including cardiovascular disease. However, the consistency of the existing literature has not been evaluated. Evidence acquisition In 2013, the authors conducted a PubMed and Web of Science review of peer reviewed articles published prior to August 2013 on the relation between violence exposure, experienced in either childhood or adulthood, and cardiovascular outcomes. To meet inclusion criteria, articles had to present estimates for the relation between violence exposure and cardiovascular outcomes (hypertension, blood pressure, stroke, coronary disease, or myocardial infarction) adjusted for demographic factors. Articles focusing on violence from TV, video games, natural disasters, terrorism, or war were excluded. Evidence synthesis The initial search yielded 2,273 articles; after removing duplicates and applying inclusion and exclusion criteria, 30 articles were selected for review. A consistent positive relation was noted on the association between violence experienced during childhood and cardiovascular outcomes in adulthood (i.e., hypertension, coronary heart disease, and myocardial infarction). Associations across genders with varying types of violence exposure were also noted. By contrast, findings were mixed on the relation between adult violence exposure and cardiovascular outcome. Conclusions Despite varying definitions of violence exposure and cardiovascular endpoints, a consistent relation exists between childhood violence exposure, largely assessed retrospectively, and cardiovascular endpoints. Findings are mixed for the adult violence–cardiovascular health relation. The cross-sectional nature of most adult studies and the reliance of self-reported outcomes can potentially be attributed to the lack of findings among adult violence exposure studies. PMID:25599905

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.

    The aim of this paper is to give an overview of acute complications of spinal cord injury (SCI). Along with motor and sensory deficits, instabilities of the cardiovascular, thermoregulatory and broncho-pulmonary system are common after a SCI. Disturbances of the urinary and gastrointestinal systems are typical as well as sexual dysfunction. Frequent complications of cervical and high thoracic SCI are neurogenic shock, bradyarrhythmias, hypotension, ectopic beats, abnormal temperature control and disturbance of sweating, vasodilatation and autonomic dysreflexia. Autonomic dysreflexia is an abrupt, uncontrolled sympathetic response, elicited by stimuli below the level of injury. The symptoms may be mild like skin rash or slight headache, but can cause severe hypertension, cerebral haemorrhage and death. All personnel caring for the patient should be able to recognize the symptoms and be able to intervene promptly. Disturbance of respiratory function are frequent in tetraplegia and a primary cause of both short and long-term morbidity and mortality is pulmonary complications. Due to physical inactivity and altered haemostasis, patients with SCI have a higher risk of venous thromboembolism and pressure ulcers. Spasticity and pain are frequent complications which need to be addressed. The psychological stress associated with SCI may lead to anxiety and depression. Knowledge of possible complications during the acute phase is important because they may be life threatening and/ or may lead to prolonged rehabilitation. PMID:25621207

    The first marathon run as an athletic event took place in the context of the Olympic Games in 1896 in Athens, Greece. Today, participation in a 'marathon run' has become a global phenomenon attracting young professional athletes as well as millions of mainly middle-aged amateur athletes worldwide each year. One of the main motives for these amateur marathon runners is the expectation that endurance exercise (EE) delivers profound beneficial health effects. However, with respect to the cardiovascular system, a controversial debate has emerged whether the marathon run itself is healthy or potentially harmful to the cardiovascular system, especially in middle-aged non-elite male amateur runners. In this cohort, exercise-induced increases in cardiac biomarkers-troponin and brain natriuretic peptide-and acute functional cardiac alterations have been observed and interpreted as potential cardiac damage. Furthermore, in the cohort of 40- to 65-year-old males engaged in intensive EE, a significant risk for the development of atrial fibrillation has been identified. Fortunately, recent studies demonstrated a normalization of the cardiac biomarkers and the functional alterations within a short time frame. Therefore, these alterations may be perceived as physiological myocardial reactions to the strenuous exercise and the term 'cardiac fatigue' has been coined. This interpretation is supported by a recent analysis of 10.9 million marathon runners demonstrating that there was no significantly increased overall risk of cardiac arrest during long-distance running races. In conclusion, intensive and long-lasting EE, e.g. running a full-distance Marathon, results in high cardiovascular strain whose clinical relevance especially for middle-aged and older athletes is unclear and remains a matter of controversy. Furthermore, there is a need for evidence-based recommendations with respect to medical screening and training strategies especially in male amateur runners over the age of

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.

    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 vo...

    Cardiovascular diseases are among the most frequent complications in pregnancies. Among them preexisting heart diseases including congenital heart disease, genetic cardiomyopathies, myocardial infarction and chemotherapy-induced cardiomyopathies display a special challenge for the mother and her physicians. Moreover, the incidence of cardiovascular disease induced by or associated with pregnancy, i.e. hypertensive disorders and peripartum cardiomyopathies, has increased over the past decades. In the present overview we explain why pregnancy is a stress model for the maternal heart and summarize the current knowledge on the influence of pregnancy on preexisting cardiomyopathies. We highlight recent advances in research with regard to hypertensive complications in pregnancy and peripartum cardiomyopathy (PPCM). Moreover, we summarize etiologies, risk factors, pathomechanisms, diagnosis, treatment, management and prognosis. Finally, interdisciplinarity between different clinical fields and basic science is a key requirement to avoid longterm damage to the cardiovascular system induced by pregnancy associated impacts and with this improve women's health in general.

  19. Autonomic consequences of spinal cord injury.

    Science.gov (United States)

    Hou, Shaoping; Rabchevsky, Alexander G

    2014-10-01

    Spinal cord injury (SCI) results not only in motor and sensory deficits but also in autonomic dysfunctions. The disruption of connections between higher brain centers and the spinal cord, or the impaired autonomic nervous system itself, manifests a broad range of autonomic abnormalities. This includes compromised cardiovascular, respiratory, urinary, gastrointestinal, thermoregulatory, and sexual activities. These disabilities evoke potentially life-threatening symptoms that severely interfere with the daily living of those with SCI. In particular, high thoracic or cervical SCI often causes disordered hemodynamics due to deregulated sympathetic outflow. Episodic hypertension associated with autonomic dysreflexia develops as a result of massive sympathetic discharge often triggered by unpleasant visceral or sensory stimuli below the injury level. In the pelvic floor, bladder and urethral dysfunctions are classified according to upper motor neuron versus lower motor neuron injuries; this is dependent on the level of lesion. Most impairments of the lower urinary tract manifest in two interrelated complications: bladder storage and emptying. Inadequate or excessive detrusor and sphincter functions as well as detrusor-sphincter dyssynergia are examples of micturition abnormalities stemming from SCI. Gastrointestinal motility disorders in spinal cord injured-individuals are comprised of gastric dilation, delayed gastric emptying, and diminished propulsive transit along the entire gastrointestinal tract. As a critical consequence of SCI, neurogenic bowel dysfunction exhibits constipation and/or incontinence. Thus, it is essential to recognize neural mechanisms and pathophysiology underlying various complications of autonomic dysfunctions after SCI. This overview provides both vital information for better understanding these disorders and guides to pursue novel therapeutic approaches to alleviate secondary complications. PMID:25428850

    Cardiovascular tissue engineering offers the promise of biologically based repair of injured and damaged blood vessels, valves, and cardiac tissue. Major advances in cardiovascular tissue engineering over the past few years involve improved methods to promote the establishment and differentiation of induced pluripotent stem cells (iPSCs), scaffolds from decellularized tissue that may produce more highly differentiated tissues and advance clinical translation, improved methods to promote vascularization, and novel in vitro microphysiological systems to model normal and diseased tissue function. iPSC technology holds great promise, but robust methods are needed to further promote differentiation. Differentiation can be further enhanced with chemical, electrical, or mechanical stimuli. PMID:27303643

    Several lines of epidemical evidence have shown that type 2 diabetes is the most important risk factor for cardiovascular diseases (CVD). It has been shown that the risk of primary prevention of CVD in patients with diabetes is equal to that of the secondary prevention in general population. In this manuscript, recent reports on the cardiac tests to detect the cardiovascular lesions will be reviewed. The data suggest that MDCT is a promising test even in the patients with diabetes. Furthermore, recent evidence of the treatment of diabetes with insulin or the drugs available recently such as DPP-4 inhibitors and SGLT-2 inhibitors will be reviewed. PMID:26666152

    2012-01-01

    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.

    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.

    Full Text Available Despite significant advances in wound care of patients with burn injuries, inhalation injury remains as an important contributor to morbidity and mortality in these patients. Unfortunately, there are limited studies that have focused on the diagnosis, grading, pathophysiology, and therapy of inhalation injury, therefore a widely accepted consensus is lacking on these topics. Inhalation injury is generally defined as the inhalation of thermal or chemical irritants and can be divided into three types of injury: thermal injury, which is mostly restricted to the upper airway; chemical injury, which affects tracheobronchial tree; and systemic toxicity owing to toxic gases such as carbon monoxide. Inhalation injury increases the burn injury associated morbidity and mortality by causing airway problems and respiratory failure during the early phase and by contributing to the development of pneumonia and atelectasis during the late phase. Additionally, systemic effects of toxic gases such as carbon monoxide may also adversely affect the early and long-term outcome in burn victims. The early diagnosis and therapy of these problems plays a key role in improving the outcome of burn patients. (Journal of the Turkish Society Intensive Care 2011; 9 Suppl: 37-45

  7. Nitric oxide in microgravity-induced orthostatic intolerance: relevance to spinal cord injury

    2003-01-01

    Prolonged exposure to microgravity results in cardiovascular deconditioning which is marked by orthostatic intolerance in the returning astronauts and recovering bed-ridden patients. Recent studies conducted in our laboratories at University of California, Irvine have revealed marked elevation of nitric oxide (NO) production in the kidney, heart, brain, and systemic arteries coupled with significant reduction of NO production in the cerebral arteries of microgravity-adapted animals. We have further demonstrated that the observed alteration of NO metabolism is primarily responsible for the associated cardiovascular deconditioning. Recovery from acute spinal cord injury (SCI) is frequently complicated by orthostatic intolerance that is due to the combined effects of the disruption of efferent sympathetic pathway and cardiovascular deconditioning occasioned by prolonged confinement to bed. In this presentation, I will review the nature of altered NO metabolism and its role in the pathogenesis of microgravity-induced cardiovascular deconditioning. The possible relevance of the new findings to orthostatic intolerance in patients with acute SCI and its potential therapeutic implications will be discussed.

  8. Marijuana Use and Cardiovascular Disease.

    2016-01-01

    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.

    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. Embora o tratamento na DEA com drogas antipsicóticas tenha se expandido, é necessária a observação cuidadosa de efeitos colaterais destes fármacos. Nesta linha, dados recentes têm associado o uso de antipsicóticos com efeitos adversos cardiovasculares (como prolongamento do intervalo QT, sugerindo que possa haver uma correlação com morte súbita. Evidências originadas em dados epidemiológicos e estudos de caso-controle indicam que o Omega-3 reduz o risco de mortalidade por causa cardiovascular, particularmente a morte súbita de origem cardíaca. Concordante com estes achados, como o Omega-3 per se tem um papel protetor cardiovascular direto, nosso artigo levanta a hipótese que a suplementação de ácidos graxos Omega-3 em pacientes com DEA tratados com drogas antipsic

    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.

    Cardiovascular risk and related medical burden due to influenza in patients with chronic disease were higher than those of healthy subjects. As a result, influenza vaccination is recommended as a strategy for secondary prevention in cardiovascular disease by major cardiovascular organizations, but the prevalence of influenza vaccination in these population is still low. Whether influenza vaccine can prevent cardiovascular events such as myocardial infarction and death is still controversial based on current evidences from observational studies and case-control studies, which may result from study desion,subjects selection,outcome definition and sample size issues. Recent meta-analysis showed that influenza vaccination may reduce cardiovascular risk, but large-scale random controlled trials with adequately power should be conducted to confirm these findings as well as the target population for this strategy further.

    Sedentary lifestyle and overweight are major public health, clinical, and economical problems in modern societies. The worldwide epidemic of excess weight is due to imbalance between physical activity and dietary energy intake. Sedentary lifestyle, unhealthy diet, and consequent overweight and obesity markedly increase the risk of cardiovascular diseases. Regular physical activity 45-60 min per day prevents unhealthy weight gain and obesity, whereas sedentary behaviors such as watching television promote them. Regular exercise can markedly reduce body weight and fat mass without dietary caloric restriction in overweight individuals. An increase in total energy expenditure appears to be the most important determinant of successful exercise-induced weight loss. The best long-term results may be achieved when physical activity produces an energy expenditure of at least 2,500 kcal/week. Yet, the optimal approach in weight reduction programs appears to be a combination of regular physical activity and caloric restriction. A minimum of 60 min, but most likely 80-90 min of moderate-intensity physical activity per day may be needed to avoid or limit weight regain in formerly overweight or obese individuals. Regular moderate intensity physical activity, a healthy diet, and avoiding unhealthy weight gain are effective and safe ways to prevent and treat cardiovascular diseases and to reduce premature mortality in all population groups. Although the efforts to promote cardiovascular health concern the whole population, particular attention should be paid to individuals who are physically inactive, have unhealthy diets or are prone to weight gain. They have the highest risk for worsening of the cardiovascular risk factor profile and for cardiovascular disease. To combat the epidemic of overweight and to improve cardiovascular health at a population level, it is important to develop strategies to increase habitual physical activity and to prevent overweight and obesity in

    2016-01-01

    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

    Full Text Available Cardiovascular disease is the leading cause of death for both men and women worldwide. Much emphasis has been placed on the primary and secondary prevention of cardiovascular disease. While depression and anxiety increase the risk of developing cardiovascular disease, cardiovascular disease also increases the risk of developing anxiety and depression. Thus, promoting optimal mental health may be important for both primary and secondary prevention of cardiovascular disease. Like lowering blood pressure, lipids, and body weight, lowering anger and hostility and improving depression and anxiety may also be an important intervention in preventive cardiology. As we strive to further improve cardiovascular outcomes, the next bridge to cross may be one of offering patients nonpharmacologic means for combating daily mental stress and promoting mental health, such as yoga and pranayama. Indeed, the best preventive cardiovascular medicine may be a blend of both Western and Eastern medicine.

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.

  14. Prodrugs in Cardiovascular Therapy

    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.

  15. Cardiovascular and interventional radiology

    International Nuclear Information System (INIS)

    This year's cardiovascular section demonstrates a continued growth in the number of digests on cardivascular and general interventional topics and continued progress in MRI studies. The reader will also notice fewer digests on DSA and percutaneous stone removal compared with the 1985 and 1986 Year Books. While newer technology, such as extracorporeal shock wave lithotripsy, has significantly reduced the number of percutaneous procedures for renal calculi, other interventional procedures, such as those involving fibrinolysis, are increasing by leaps and bounds. A number of digests on benign and malignant bile duct strictures continue to shed light on the management of these difficult cases. While abscess drainage is growing and well accepted by most surgeons, articles on esophageal dilatations seem to be declining in the radiology literature, probably on the basis of fewer operations being performed by us and more being performed by endoscopists. Digests on MRI in the cardiovascular system continue to report excellent images of the aorta and of congenital heart disease

  16. Cardiovascular: radioisotopic angiocardiography

    International Nuclear Information System (INIS)

    Radioisotopic angiocardiography, performed after the intravenous injection of 99/sup m/Tc-labeled pertechnetate or albumin, is a simple, rapid, and safe procedure which permits identification and physiologic assessment of a wide variety of congenital and acquired cardiovascular lesions in infants and children. These include atrial and ventricular septal defect, tetralogy of Fallot, pulmonic stenosis, aortopulmonary window, transposition of the great vessels, valvular stenosis and/or insufficiency, myocardial lesions, and lesions of the great vessels. The simplicity of the procedure lends itself to repeated measurements to assess the effects of therapy or to follow the course of the disease. A wide spectrum of congenital and acquired cardiovascular diseases have been studied which have particular application to the pediatric age group. (auth)

    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.

    Mediastinal radiation damages endothelial cells, with resulting loss of capillaries and ischemia at the level of the microcirculation. These changes lead to increases in collagen and proliferation of fibrous tissue throughout the heart. Cardiac dysfunction following radiotherapy is surprisingly common and may be due to pericardial, myocardial, valvular, conduction system, or coronary artery disease. Greater awareness of cardiotoxicity has prompted changes in radiation techniques that appear to reduce clinical cardiovascular complications.135 references.

  3. Cardiovascular tissues contain independent circadian clocks

    Acute cardiovascular events exhibit a circadian rhythm in the frequency of occurrence. The mechanisms underlying these phenomena are not yet fully understood, but they may be due to rhythmicity inherent in the cardiovascular system. We have begun to characterize rhythmicity of the clock gene mPer1 in the rat cardiovascular system. Luciferase activity driven by the mPer1 gene promoter is rhythmic in vitro in heart tissue explants and a wide variety of veins and arteries cultured from the transgenic Per1-luc rat. The tissues showed between 3 and 12 circadian cycles of gene expression in vitro before damping. Whereas peak per1-driven bioluminescence consistently occurred during the late night in the heart and all arteries sampled, the phases of the rhythms in veins varied significantly by anatomical location. Varying the time of the culture procedure relative to the donor animal's light:dark cycle revealed that, unlike some other rat tissues such as liver, the phases of in vitro rhythms of arteries, veins, and heart explants were affected by culture time. However, phase relationships among tissues were consistent across culture times; this suggests diversity in circadian regulation among components of the cardiovascular system.

    2015-12-01

    Patients with rheumatoid arthritis (RA) and other inflammatory joint diseases (IJDs) have an increased risk of premature death compared with the general population, mainly because of the risk of cardiovascular disease, which is similar in patients with RA and in those with diabetes mellitus. Pathogenic mechanisms and clinical expression of cardiovascular comorbidities vary greatly between different rheumatic diseases, but atherosclerosis seems to be associated with all IJDs. Traditional risk factors such as age, gender, dyslipidaemia, hypertension, smoking, obesity and diabetes mellitus, together with inflammation, are the main contributors to the increased cardiovascular risk in patients with IJDs. Although cardiovascular risk assessment should be part of routine care in such patients, no disease-specific models are currently available for this purpose. The main pillars of cardiovascular risk reduction are pharmacological and nonpharmacological management of cardiovascular risk factors, as well as tight control of disease activity. PMID:26282082

  8. Free Radicals and Antioxidants in Cardiovascular Health and Disease

    Directory of Open Access Journals (Sweden)

    Ms. V Luximon-Ramma

    2006-07-01

    Full Text Available Current hypotheses favour the concept that lowering oxidative stress can have a health benefit. Free radicals can be overproduced or the natural antioxidant system defenses weakened, first resulting in oxidative stress, and then leading to oxidative injury and disease. Cardiovascular disease is one example of this process. This disorder continues to be the major cause of premature death worldwide. Oxidation of human low-density lipoproteins is considered an early step in the progression and eventual development of atherosclerosis, one of the leading causes to cardiovascular dysfunction. Compelling support for the involvement of free radicals in disease development originates from epidemiological studies showing that an enhanced antioxidant status is associated with reduced risk of several diseases. Dietary nutraceuticals such as vitamins C, E and polyphenolics and reduction of cardiovascular disease incidence are a notable example. This paper reviews the biology of ROS/RNS, their pathways through which they relate to the pathology of cardiovascular disease and discusses the putative roles that antioxidants, including phenolics, may play in controlling oxidative stress and reduce the incidence of cardiovascular disease.

  10. Reduction of cardiovascular risk in chronic kidney disease by mineralocorticoid receptor antagonism.

    Science.gov (United States)

    Epstein, Murray

    2015-12-01

    Cardiovascular disease is the leading cause of death and morbidity in people with chronic kidney disease, but there are few evidence-based treatments for reducing cardiovascular events in these patients. The failure of novel drug candidates to delay progression to end-stage renal disease and limit or abrogate cardiovascular morbidity and mortality has led to increased interest in a mineralocorticoid receptor (MR) antagonist-based treatment model to reduce cardiovascular risk in patients with chronic kidney disease and end-stage renal disease. Aldosterone concentrations and MR signalling are associated with an enhanced risk of cardiovascular injury and the incidence of sudden death, and MR blockade decreases the risk of cardiovascular events and sudden death in patients with reduced glomerular filtration rate. Since evidence from clinical trials shows that treatment with MR antagonists confers a morbidity and mortality advantage for patients with cardiovascular disorders, similar benefits might also accrue in patients with chronic kidney disease. Large prospective trials are urgently needed to answer this question. In this Review, I argue that despite differences in the pathophysiology and clinical features of cardiovascular disease in patients with and without chronic kidney disease, MR antagonists could provide cardiovascular benefit in patients with chronic kidney disease.

Seeing the occupational physician beforehand, so as to anticipate the return to work, is crucial. Dialogue between cardiologists, general practitioners and occupational physician, still observing medical confidentiality, must allow a better quality of return to work. Being recognized as a handicapped worker is a key element in the prevention of socio-professional exclusion.

    Hyperuricemia, gout as well as arterial hypertension and metabolic syndrom are highly prevalent and clinicians are frequently confronted with both conditions in the same patient. Hyperuricemia and gout are associated with cardiovascular comorbidities and a high cardiovascular risk. Despite coherent pathophysiological concepts, it remains to be determined, if this association is independent and causal. In daily clinical practice, cardiovascular risk factors should be thoroughly identified and consequently treated in all patients with hyperuricemia and gout. If preventive treatment of asymptomatic hyperuricemia with urate-lowering agents may improve cardiovascular risk and outcomes remains to be determined and is recommended only in special situations like young patients with severe hyperuricemia.

    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 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.

    2014-09-01

    It is well established that thyroid hormones affect the cardiovascular system through genomic and nongenomic actions. TRalpha1 is the major thyroid hormone receptor in the heart. T3 suppresses increased mitotic activity of stimulated cardiomyocytes. Hyperthyroidism induces a hyperdynamic cardiovascular state, which is associated with enhanced left ventricular systolic and diastolic function and the chronotropic and inotropic properties of thyroid hormones. Hypothyroidism, however, is characterized by opposite changes. In addition, thyroid hormones decrease peripheral vascular resistance, influence the rennin-angiotensin system (RAS), and increase blood volume and erythropoetin secretion with subsequent increased preload and cardiac output. Thyroid hormones play an important role in cardiac electrophysiology and have both pro- and anti-arrhytmic potential. Thyroid hormone deficiency is associated with a less favorable lipid profile. Selective modulation of the TRbeta1 receptor is considered as a potential therapeutic target to treat dyslipidemia without cardiac side effects. Thyroid hormones have a beneficial effect on limiting myocardial ischemic injury, preventing and reversing cardiac remodeling and improving cardiac hemodynamics in endstage heart failure. This is crucial because a low T3 syndrome accompanies both acute and chronic cardiac diseases. PMID:25345279

    Quantification of circulating endothelial cells (CECs) in peripheral blood is developing as a novel and reproducible method of assessing endothelial damage/dysfunction. The CECs are thought to be mature cells that have detached from the intimal monolayer in response to endothelial injury and are a different cell population to endothelial progenitor cells (EPCs). The EPCs are nonleukocytes derived from the bone marrow that are believed to have proliferative potential and may be important in vascular regeneration. Currently accepted methods of CEC quantification include the use of immunomagnetic bead separation (with cell counting under fluorescence microscopy) and flow cytometry. Several recent studies have shown increased numbers of CECs in cardiovascular disease and its risk factors, such as unstable angina, acute myocardial infarction, stroke, diabetes mellitus, and critical limb ischemia, but no change in stable intermittent claudication, essential hypertension, or atrial fibrillation. Furthermore, CEC quantification at 48 h after acute myocardial infarction has been shown to be an accurate predictor of major adverse coronary events and death at both 1 month and 1 year. This article presents an overview of the pathophysiology of CECs in the setting of cardiovascular disease and a brief comparison with EPCs. PMID:17045885

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 The impact of environmental noise on public health, in The Netherlands, is limited: Less than 1% of the myocardial infarction cases per year are attributable to long-term exposure to road traffic noise. Furthermore, although the Dutch noise policy is not directed to prevent cardiovascular disease due to noise exposure, health does play a role in Dutch noise policy. These are the main conclusions of a systematic review of Dutch observational studies, investigating the possible impact of road traffic and aircraft noise exposure on the cardiovascular system. Since 1970, 14 Dutch studies were published investigating the possible impact of road traffic and aircraft noise exposure on the cardiovascular system. Within these studies a large variety of outcomes were investigated, ranging from blood pressure changes to cardiovascular mortality. The results of the studies were not consistent and only weak associations were found.

  2. Assessment of cardiovascular risk.

    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?

    Full Text Available Edoardo Mannucci,1 Stefano Giannini,2 Ilaria Dicembrini1 1Diabetes Agency, Careggi Teaching Hospital, Florence, 2Section of Endocrinology, Department of Biomedical Clinical and Experimental Sciences, University of Florence and Careggi University Hospital, Florence, Italy Abstract: Basal insulin is an important component of treatment for both type 1 and type 2 diabetes. One of the principal aims of treatment in patients with diabetes is the prevention of diabetic complications, including cardiovascular disease. There is some evidence, although controversial, that attainment of good glycemic control reduces long-term cardiovascular risk in both type 1 and type 2 diabetes. The aim of this review is to provide an overview of the potential cardiovascular safety of the different available preparations of basal insulin. Current basal insulin (neutral protamine Hagedorn [NPH], or isophane and basal insulin analogs (glargine, detemir, and the more recent degludec differ essentially by various measures of pharmacokinetic and pharmacodynamic effects in the bloodstream, presence and persistence of peak action, and within-subject variability in the glucose-lowering response. The currently available data show that basal insulin analogs have a lower risk of hypoglycemia than NPH human insulin, in both type 1 and type 2 diabetes, then excluding additional harmful effects on the cardiovascular system mediated by activation of the adrenergic system. Given that no biological rationale for a possible difference in cardiovascular effect of basal insulins has been proposed so far, available meta-analyses of publicly disclosed randomized controlled trials do not show any signal of increased risk of major cardiovascular events between the different basal insulin analogs. However, the number of available cardiovascular events in these trials is very small, preventing any clear-cut conclusion. The results of an ongoing clinical trial comparing glargine and degludec with

    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.)

    Despite the evolution of Irish dance to professional status in recent decades, only scant investigation of musculoskeletal pain and injury among professional Irish dancers (PIDs) has been undertaken. This study investigated the rate of injury and associated factors among 178 PIDs, using an online questionnaire. One hundred and thirty-seven PIDs (76.7%) reported a previous injury, with the foot (67.9%) and ankle (60.6%) most commonly affected. A mean career rate of 2.25 injuries per dancer was computed. The majority of injuries were minor in nature, and almost half occurred midway through a tour. Sixty subjects (33.7%) reported that they often or always danced in pain. The main contributory factors to injury were accidents, fatigue or overwork, repetitive movements, and unsafe stages. Warm-up (98.8%) and cool-down (84.3%) were almost universally practised, with cross-training engaged in by 124 PIDs (74.7%). Popular treatments used to prevent and manage injuries were massage (N = 137, or 83.0% of PIDs), stretching (N = 117, or 70.1%) and physiotherapy (N = 105, or 62.9%). There was a moderate level of psychological distress among the participants, with "interpersonal difficulties" and "tension with people" the main problems cited. PIDs who were older (p = 0.008) and more experienced (p = 0.002) reported missing a greater number of performances due to injury. There were no other significant relationships between injury and factors, including gender, frequency of dancing in pain, use of warm-up, cool-down, or cross-training. Further prospective studies of PIDs should consider both physical and biopsychosocial elements to generate an appropriate screening process to predict those at risk of injury. PMID:24565330

A associação entre SAOS e doença cardiovascular não é somente uma consequência da sobreposição de fatores de risco, incluindo obesidade, sedentarismo, ser do sexo masculino e ter idade maior. Existem evidências crescentes de que SAOS contribui de forma independente para o aparecimento e a progressão de várias doenças cardiovasculares. Os mecanismos pelos quais SAOS pode afetar o sistema cardiovascular são múltiplos e incluem a ativação do sistema nervoso simpático, inflamação sistêmica, resistência a insulina e geração de estresse oxidativo. Existem evidências que o tratamento de SAOS com CPAP pode reduzir a pressão arterial, sinais precoces de aterosclerose, risco de recorrência de fibrilação atrial e mortalidade, principalmente por acidente vascular cerebral e infarto agudo do miocárdio, em pacientes com SAOS grave.Obstructive sleep apnea syndrome (OSAS is a common condition associated with various cardiovascular diseases, including systemic arterial hypertension, atrial fibrillation, and atherosclerosis. The association between OSAS and cardiovascular disease has been related to the overlapping of risk factors, including obesity, having a sedentary lifestyle, being male, and being older. However, there is mounting evidence that OSAS can also independently contribute to the development and progression of various cardiovascular diseases. The mechanisms by which OSAS can affect the cardiovascular system are multiple, including the activation of the sympathetic nervous system, systemic inflammation, insulin resistance, and oxidative stress. There is also evidence that the treatment of OSAS with CPAP can reduce arterial blood pressure, early signs of atherosclerosis, the risk of atrial fibrillation recurrence, and mortality (principally

    2015-06-01

    Full Text Available In recent years, platelet proteomics has been applied successfully to the study of cardiovascular diseases (CVDs. It is very well known that platelets play a pivotal role in the pathophysiological mechanisms underlying many CVDs, especially acute coronary syndromes (ACSs, since they are implied in thrombus formation after atheroma plaque rupture. This is the reason why molecules involved in platelet activation and aggregation are primary targets for treatment of ACSs. Many efforts are aimed at finding drugs that inhibit platelet activation; however it is difficult to separate the therapeutic benefits from harmful effects because pathological and physiological functions of platelets are due to the same mechanisms. Given that platelets lack a nucleus, proteomics is regarded as an ideal method to approach their biochemistry. Current platelet proteomic studies are focusing on the identification of platelet molecular and functional changes in normal and pathological states, enriching the comprehension of platelet biological function, and screening for new biomarkers and antiplatelet agents. In the present article, we introduce the reader to platelet biology and function, and revise recent advances in platelet proteomics applied to the study of CVDs, including a special emphasis on sample preparation requirements for proteome analysis of platelet clinical samples.

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.

    Full Text Available BACKGROUND: The average lifespan of humans is increasing, and with it the percentage of people entering the 65 and older age group is growing rapidly and will continue to do so in the next 20 years. Within this age group, cardiovascular disease will remain the leading cause of death, and the cost associated with treatment will continue to increase. Aging is an inevitable part of life and unfortunately poses the largest risk factor for cardiovascular disease. CONTENT: We provide an overview of some of the molecular mechanisms involved in regulating lifespan and health, including mitochondria, telomeres, stem cells, sirtuins, Adenosine Monophosphate-activated Protein Kinase, Mammalian Target of Rapamycin and Insulin-like Growth Factor 1. We also provide future perspectives of lifespan and health, which are intimately linked fields. SUMMARY: Aging remains the biggest non-modifiable risk factor for cardiovascular disease. The biological, structural and mechanical changes in senescent cardiovascular system are thought to contribute in increasing incidence of cardiovascular disease in aging. Understanding the mechanisms contributing to such changes is therefore crucial for both prevention and development of treatment for cardiovascular diseases.

    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 Trials of peroxisome proliferator-activated receptor (PPAR agonists have shown mixed results for cardiovascular prevention. Fibrates are PPAR- agonists that act primarily to improve dyslipidemia. Based on low- and high-density lipoprotein cholesterol (LDL and HDL effects, gemfibrozil may be of greater cardiovascular benefit than expected, fenofibrate performed about as expected, and bezafibrate performed worse than expected. Increases in both cardiovascular and noncardiovascular serious adverse events have been observed with some fibrates. Thiazolidinediones (TZDs are PPAR- agonists used to improve impaired glucose metabolism but also influence lipids. Pioglitazone reduces atherosclerotic events in diabetic subjects, but has no net cardiovascular benefit due to increased congestive heart failure risk. Rosiglitazone may increase the risk of atherosclerotic events, and has a net harmful effect on the cardiovascular system when congestive heart failure is included. The primary benefit of TZDs appears to be the prevention of diabetic microvascular complications. Dual PPAR-/ agonists have had unacceptable adverse effects but more selective agents are in development. PPAR- and pan-agonists are also in development. It will be imperative to prove that future PPAR agonists not only prevent atherosclerotic events but also result in a net reduction on total cardiovascular events without significant noncardiovascular adverse effects with long-term use.

    The practice of contrast-enhanced magnetic resonance angiography (CEMRA) has changed significantly in the span of a decade. Concerns regarding gadolinium (Gd)-associated nephrogenic systemic fibrosis in those with severely impaired renal function spurred developments in low-dose CEMRA and non-contrast MRA as well as efforts to seek alternative MR contrast agents. Originally developed for MR imaging use, ferumoxytol (an ultra-small superparamagnetic iron oxide nanoparticle), is currently approved by the US Food and Drug Administration for the treatment of iron deficiency anaemia in adults with renal disease. Since its clinical availability in 2009, there has been rising interest in the scientific and clinical use of ferumoxytol as an MR contrast agent. The unique physicochemical and pharmacokinetic properties of ferumoxytol, including its long intravascular half-life and high r1 relaxivity, support a spectrum of MRI applications beyond the scope of Gd-based contrast agents. Moreover, whereas Gd is not found in biological systems, iron is essential for normal metabolism, and nutritional iron deficiency poses major public health challenges worldwide. Once the carbohydrate shell of ferumoxytol is degraded, the elemental iron at its core is incorporated into the reticuloendothelial system. These considerations position ferumoxytol as a potential game changer in the field of CEMRA and MRI. In this paper, we aim to summarise our experience with the cardiovascular applications of ferumoxytol and provide a brief synopsis of ongoing investigations on ferumoxytol-enhanced MR applications.

  4. Radiopharmaceuticals in cardiovascular diseases

    International Nuclear Information System (INIS)

    The high incidence of cardiovascular disorders and the attendant morbidity and mortality have encouraged the development of new radiopharmaceuticals for the diagnosis and localisation of coronary diseases. Myocardial perfusion imaging is an invaluable tool for the demonstration of transient ischemia and infarction in heart and identification of viable and non-viable myocardial tissue. Thallium chloride (Tl-201) is the agent currently in wide use but its drawbacks have been well recognised. Hence tremendous amount of research work has been carried out to develop a suitable Tc-99m radiopharmaceutical for this purpose which has resulted in the introduction of two Tc-99m labelled radiopharmaceuticals HEXAMIBI and BATO. These are being tried as myocardial imaging agents these days and the choice amongst these depends on concrete clinical situation. The experimental work involving the synthesis of ligand MIBI, formulation into freeze dried KIT form, quality control procedure, biodistribution studies and finally clinical evaluation of locally produced KIT in human volunteers has now been reported here. Our KIT has been produced for the first time in Pakistan and has been tried on forty five patients in Nuclear Medical Centre, AFIP (Rawalpindi). The results obtained are comparable to those of Ti-201 with a slightly higher liver background in case of MIBI but because of the easy availability MIBI has become agent of choice for myocardial perfusion studies.

    SIRT3 belongs to a highly conserved protein family of histone deacetylases and it is rich in mitochondria. As acetyl-modification is one of the important post-translational modifications that prevail in the mitochondria, it is not surprising that SIRT3 plays a key regulatory role in this organelle. SIRT3 has a wide range of substrates that are involved in the physiological and pathological processes of oxidative stress, ischemia-reperfusion injury, mitochondrial metabolism homeostasis and cellular death. These pathophysiological processes are considered as the underlying mechanisms of diseases like cardiac hypertrophy, myocardial infarction and heart failure, indicating the potential roles of SIRT3 in cardiovascular diseases. In this review, we will summarize the emerging roles and therapeutic implications of SIRT3 in cardiovascular diseases by providing an update on the latest understanding of its functions.

    2016-01-01

    Stroke and other neurovascular derangements are main causes of global death. They, along with spinal cord injuries, are responsible for being the principal cause of disability due to neurological and cognitive problems. These problems then lead to a burden on scarce financial resources and societal care facilities as well as have a profound effect on patients' families. The mechanism of action in these debilitating diseases is complex and unclear. An important component of these problems arises from derangement of blood vessels, such as blockage due to clotting/embolism, endothelial dysfunction, and overreactivity to contractile agents, as well as alteration in endothelial permeability. Moreover, the cerebro-vasculature (large vessels and arterioles) is involved in regulating blood flow by facilitating auto-regulatory processes. Moreover, the anterior (middle cerebral artery and the surrounding region) and posterior (basilar artery and its immediate locality) regions of the brain play a significant role in triggering the pathological progression of ischemic stroke particularly due to inflammatory activity and oxidative stress. Interestingly, modifiable and non-modifiable cardiovascular risk factors are responsible for driving ischemic and hemorrhagic stroke and spinal cord injury. There are different stroke animal models to examine the pathophysiology of middle cerebral and basilar arteries. In this context, arterial myography offers an opportunity to determine the etiology of vascular dysfunction in these diseases. Herein, we describe the technique of pressure myography to examine the reactivity of cerebral vessels to contractile and vasodilator agents and a prelude to stroke and spinal cord injury.

    The effects of space flight on the cardiovascular system have been studied since the first manned flights. In several instances, the results from these investigations have directly contradicted the predictions based on established models. Results suggest associations between space flight's effects on other organ systems and those on the cardiovascular system. Such findings provide new insights into normal human physiology. They must also be considered when planning for the safety and efficiency of space flight crewmembers.

    Mannucci, Edoardo; Giannini, Stefano; Dicembrini, Ilaria

    2015-01-01

    Basal insulin is an important component of treatment for both type 1 and type 2 diabetes. One of the principal aims of treatment in patients with diabetes is the prevention of diabetic complications, including cardiovascular disease. There is some evidence, although controversial, that attainment of good glycemic control reduces long-term cardiovascular risk in both type 1 and type 2 diabetes. The aim of this review is to provide an overview of the potential cardiovascular safety of the different available preparations of basal insulin. Current basal insulin (neutral protamine Hagedorn [NPH], or isophane) and basal insulin analogs (glargine, detemir, and the more recent degludec) differ essentially by various measures of pharmacokinetic and pharmacodynamic effects in the bloodstream, presence and persistence of peak action, and within-subject variability in the glucose-lowering response. The currently available data show that basal insulin analogs have a lower risk of hypoglycemia than NPH human insulin, in both type 1 and type 2 diabetes, then excluding additional harmful effects on the cardiovascular system mediated by activation of the adrenergic system. Given that no biological rationale for a possible difference in cardiovascular effect of basal insulins has been proposed so far, available meta-analyses of publicly disclosed randomized controlled trials do not show any signal of increased risk of major cardiovascular events between the different basal insulin analogs. However, the number of available cardiovascular events in these trials is very small, preventing any clear-cut conclusion. The results of an ongoing clinical trial comparing glargine and degludec with regard to cardiovascular safety will provide definitive evidence. PMID:26203281

    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.

    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. PMID:18006557

    2016-05-27

    The prevalence of obesity has increased worldwide over the past few decades. In 2013, the prevalence of obesity exceeded the 50% of the adult population in some countries from Oceania, North Africa, and Middle East. Lower but still alarmingly high prevalence was observed in North America (≈30%) and in Western Europe (≈20%). These figures are of serious concern because of the strong link between obesity and disease. In the present review, we summarize the current evidence on the relationship of obesity with cardiovascular disease (CVD), discussing how both the degree and the duration of obesity affect CVD. Although in the general population, obesity and, especially, severe obesity are consistently and strongly related with higher risk of CVD incidence and mortality, the one-size-fits-all approach should not be used with obesity. There are relevant factors largely affecting the CVD prognosis of obese individuals. In this context, we thoroughly discuss important concepts such as the fat-but-fit paradigm, the metabolically healthy but obese (MHO) phenotype and the obesity paradox in patients with CVD. About the MHO phenotype and its CVD prognosis, available data have provided mixed findings, what could be partially because of the adjustment or not for key confounders such as cardiorespiratory fitness, and to the lack of consensus on the MHO definition. In the present review, we propose a scientifically based harmonized definition of MHO, which will hopefully contribute to more comparable data in the future and a better understanding on the MHO subgroup and its CVD prognosis.

    Full Text Available Abstract Background Several studies have correlated elevations in cardiac biomarkers of injury post marathon with transient and reversible right ventricular (RV systolic dysfunction as assessed by both transthoracic echocardiography (TTE and cardiovascular magnetic resonance (CMR. Whether or not permanent myocardial injury occurs due to repeated marathon running in the aging population remains controversial. Objectives To assess the extent and severity of cardiac dysfunction after the completion of full marathon running in individuals greater than 50 years of age using cardiac biomarkers, TTE, cardiac computed tomography (CCT, and CMR. Methods A total of 25 healthy volunteers (21 males, 55 ± 4 years old from the 2010 and 2011 Manitoba Full Marathons (26.2 miles were included in the study. Cardiac biomarkers and TTE were performed one week prior to the marathon, immediately after completing the race and at one-week follow-up. CMR was performed at baseline and within 24 hours of completion of the marathon, followed by CCT within 3 months of the marathon. Results All participants demonstrated an elevated cTnT post marathon. Right atrial and ventricular volumes increased, while RV systolic function decreased significantly immediately post marathon, returning to baseline values one week later. Of the entire study population, only two individuals demonstrated late gadolinium enhancement of the subendocardium in the anterior wall of the left ventricle, with evidence of stenosis of the left anterior descending artery on CCT. Conclusions Marathon running in individuals over the age of 50 is associated with a transient, yet reversible increase in cardiac biomarkers and RV systolic dysfunction. The presence of myocardial fibrosis in older marathon athletes is infrequent, but when present, may be due to underlying occult coronary artery disease.

  10. Dietary fibre and cardiovascular health.

    Sánchez-Muniz, F J

    2012-01-01

    Cardiovascular disease (CVD) is the leading cause of mortality and morbidity in developed countries. CVD is an inflammatory disease associated with risk factors that include hypercholesterolemia and hypertension. Furthermore, the evolution of this disease depends on the amount of modified lipoproteins (e.g. oxidized) present in the arterial subendothelium. Diet is considered the cornerstone for CVD treatment, as it can lower not only atherogenic lipoprotein levels and degree of oxidation, but also blood pressure, thrombogenesis and concentrations of some relevant factors (e.g. homocystein).Among different diets, the Mediterranean diet stands out due to their benefits on several health benefits, in particular with regard to CVD. Rich in vegetable foods, this diet contributes both quantitatively and qualitatively to essential fibre compounds (cellulose, hemicellulose, gums, mucilages, pectins, oligosaccharides, lignins, etc.). The present paper analyzes the effects of fibre consumption on a) cholesterol and lipoprotein levels; b) systolic and diastolic blood pressures; and c) antioxidant availability and profile. Some studies and meta-analysis are revised, as the possible mechanisms by which fibre may decrease plasma total cholesterol and LDL-cholesterol and blood pressure and to act as antioxidant, as well. In addition, author's own publications regarding the effect of fibre matrix (e.g. seaweeds) on arylesterase and the gene expression of some key antioxidant enzymes are reviewed. The paper also includes data concerning the possible interaction between fibre and some hypolipemic drugs, which may make it possible to attain similar hypolipemic effects with lower dosages, with the consequent decrease in possible side effects. The review concludes with a summary of nutritional objectives related to the consumption of carbohydrates and fibre supplements. PMID:22566302

    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.

    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.

    Progression of cardiovascular disease is often caused by a deficiency of magnesium in the human body. Magnesium belongs to the necessary vital macronutrients providing many physiological and pathological reactions and is involved in the constructive, energy, electrolyte metabolism. Correction of magnesium deficiency is realized using magnesium-containing drugs, for example magnesium orotate, having pleiotropic effects due to independent metabolic activity of orotic acid.

    Adamson, P D; Williams, M C; Newby, D E

    2016-07-01

    Cardiovascular positron-emission tomography combined with computed tomography (PET-CT) has recently emerged as an imaging technology with the potential to simultaneously describe both anatomical structures and physiological processes in vivo. The scope for clinical application of this technique is vast, but to date this promise has not been realised. Nonetheless, significant research activity is underway to explore these possibilities and it is likely that the knowledge gained will have important diagnostic and therapeutic implications in due course. This review provides a brief overview of the current state of cardiovascular PET-CT and the likely direction of future developments. PMID:26951964

  7. Vitamin D and Cardiovascular Disease

    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.

  9. Knee and ankle injuries from playing football

    International Nuclear Information System (INIS)

    Soccer is the most common sport activity worldwide. Over the last two decades the increase in soccer players has mainly been due to increased interest by females. In general, soccer is a relatively safe sport activity, especially if minor injuries resulting in short periods of absence from playing or training are neglected. However, due to the high number of soccer players severe injuries are also frequent. These are a problem not only for the injured player and the team but may also become problematic for the socio-economic system. In up to 80-90% structures of the lower extremities are injured. For sufficient radiological diagnosis knowledge of the biomechanics of the soccer game and some details about the history of the injury may be of help. To prevent soccer injuries or keep the degree of injury low, special programs had been developed. (orig.)

    The aim of this study was to evaluate the role of α-lipoic acid (α-LA) on oxidative damage and inflammation that occur in endothelium of aorta and heart while constant consumption of high-fructose corn syrup (HFCS). The rats were randomly divided into three groups with each group containing eight rats. The groups include HFCS, HFCS + α-LA treatment, and control. HFCS was given to the rats at a ratio of 30% of F30 corn syrup in drinking water for 10 weeks. α-LA treatment was given to the rats at a dose of 100 mg/kg/day orally for the last 6 weeks. At the end of the experiment, the rats were killed by cervical dislocation. The blood samples were collected for biochemical studies, and the aortic and cardiac tissues were collected for evaluation of oxidant-antioxidant system, tissue bath, and pathological examination. HFCS had increased the levels of malondialdehyde, creatine kinase MB, lactate dehydrogenase, and uric acid and showed significant structural changes in the heart of the rats by histopathology. Those changes were improved by α-LA treatment as it was found in this treatment group. Immunohistochemical expressions of tumor necrosis factor α and inducible nitric oxide synthase were increased in HFCS group, and these receptor levels were decreased by α-LA treatment. All the tissue bath studies supported these findings. Chronic consumption of HFCS caused several problems like cardiac and endothelial injury of aorta by hyperuricemia and induced oxidative stress and inflammation. α-LA treatment reduced uric acid levels, oxidative stress, and corrected vascular responses. α-LA can be added to cardiac drugs due to its cardiovascular protective effects against the cardiovascular diseases.

    2014-01-01

    Considering the impaired regenerative capacity of adult mammalian heart tissue, cardiovascular tissue engineering aims to create functional substitutes that can restore the structure and function of the damaged cardiac tissue. The success of cardiac regenerative therapies has been limited mainly due to poor control on the structure and properties of the tissue substitute, lack of vascularization, and immunogenicity. In this study we introduce a new approach to rapidly engineer dense biomimetic scaffolds consisting of type I collagen, to protect the heart against severe ischemic injury. Scaffold biomechanical properties are adjusted to mimic embryonic epicardium which is shown to be optimal to support cardiomyocyte contractile work. Moreover, the designed patch can serve as a delivery device for targeted, controlled release of cells or therapeutic macromolecules into the lesion area. PMID:25173173

    The mammalian circulatory system comprises both the cardiovascular system and the lymphatic system. In contrast to the blood vascular circulation, the lymphatic system forms a unidirectional transit pathway from the extracellular space to the venous system. It actively regulates tissue fluid homeostasis, absorption of gastrointestinal lipids, and trafficking of antigen-presenting cells and lymphocytes to lymphoid organs and on to the systemic circulation. The cardinal manifestation of lymphatic malfunction is lymphedema. Recent research has implicated the lymphatic system in the pathogenesis of cardiovascular diseases including obesity and metabolic disease, dyslipidemia, inflammation, atherosclerosis, hypertension, and myocardial infarction. Here, we review the most recent advances in the field of lymphatic vascular biology, with a focus on cardiovascular disease. PMID:26846644

    Recent advances in basic cardiovascular research as well as their translation into the clinical situation were the focus at the last "New Frontiers in Cardiovascular Research meeting". Major topics included the characterization of new targets and procedures in cardioprotection, deciphering new players and inflammatory mechanisms in ischemic heart disease as well as uncovering microRNAs and other biomarkers as versatile and possibly causal factors in cardiovascular pathogenesis. Although a number of pathological situations such as ischemia-reperfusion injury or atherosclerosis can be simulated and manipulated in diverse animal models, also to challenge new drugs for intervention, patient studies are the ultimate litmus test to obtain unequivocal information about the validity of biomedical concepts and their application in the clinics. Thus, the open and bidirectional exchange between bench and bedside is crucial to advance the field of ischemic heart disease with a particular emphasis of understanding long-lasting approaches in cardioprotection.

    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.

    It was apparent that the bed-rest and spaceflight data indicated that decreases in plasma volume and cardiac atrophy along with cardiac remodeling were fundamental changes which predisposed many astronauts to post flight orthostatic intolerance. Despite the recently acquired in-flight and post-flight muscle sympathetic nerve activity findings suggesting that the sympathetic nerve responses were appropriate there remains significant contrary data from bed-rest studies, post- flight stand tests and hind-limb unweighted rat studies that suggest that the vasoconstrictive responses were compromised at least insufficient in susceptible individuals. The key issues raised is whether a diminished increase in sympathetic activity from baseline without changes in 254 First Biennial Space Biomedical Investigators'Workshop Cardiovascular peak response or receptor adaptations is an abnormal response or is an individual variance of response to the accentuated decrease in stroke volume. Data relating autonomic neural control of heart rate were presented to suggest that the vagal and sympathetic control of heart rate was attenuated. Also, bed-rest and space flight induced attenuated baroreflex control of heart rate was shown to be restored to pre-bedrest function by one bout of maximal dynamic exercise. However, these data were confounded by relying on the use of R-R interval as a measure of efferent responses of the baroreflex during a condition in which the baseline heart rate was changed. Clearly the idea that the autonomic control of heart rate may be changed by microgravity needs further investigation. This direction is suggested despite the fact that in the triple product (HR x SV x TPR = MAP) assessment of the regulation of arterial blood pressure during orthostasis the role of the HR reflex may be less influential than that associated. with cardiac atrophy (SV changes) and aberrant sympathetic vasoconstriction (resistance) changes.

    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.

Forty-six injuries were recorded. Injury incidence was evaluated at 2.5 injuries per 1000 player-hours, with a significantly higher incidence in game injuries (14.3 injuries per 1000 game-hours compared with practice injuries(0.6 injuries per 1000 practice-hours.Practice injury incidence was higher in the lower performance level group, and game injury incidence was higher in the high-level group. The upper extremity was involved in 37% of the injuries, and the lower extremity in 54%.The knee was the most commonly injured joint, followed by the finger, ankle, and shoulder. Knee injuries were the most severe injuries, and they were more frequent in high-level players. There was an increase in the severity of injury with respect to performance level. The injury mechanism revealed a high number of offensive injuries, one-third of them occurring during a counterattack. The injury pattern showed certain variations with respect to player position and performance level.

    2004-01-01

    The aim of this article is to bring forward and realise the size of cardiovascular diseases and the burden of its numbers that concern practising doctors in Lower Silesia, in Poland, Europe and the world. Every fourth patient knocking at the GP's door comes with a problem with the circulatory system. These diseases are the reason for every second in hospitalization or referral to a specialist. The most common diagnosis is not the common cold but arterial hypertension. Three of the most common diseases in patients over 65 years old are: hypertension, ischaemic heart disease, and atherosclerosis of the brain arteries. Poland belongs to the group of developed countries with an emerging economy, where degenerative diseases dominate, and cardiovascular diseases account for the biggest problems within the Health System. Nearly half of male deaths (46%) and over half of female deaths (56%) are the consequence of cardiovascular diseases. 80% of people around the world live in developing economies, where cardiovascular diseases cause 23% of all deaths. Every fifth person lives in a developed country and has a 50% chance of dying because of cardiovascular diseases. Will these diseases become "the number one killer" of the 21st century? 27% lost healthy life years are due to arterial hypertension, ischeamic heart disease, and congestive heart failure so their epidemiology is being regarded in this article.

    Traumatic lesions of the hip in athletes may be clinically challenging because of the overlap in clinical presentation due to differing pathologies and the presence of multiple injuries. Imaging of the hip in the athlete has undergone a recent resurgence of interest and understanding related to the increasing accessibility and use of hip arthroscopy, which expands the treatment options available for intra-articular pathology. MR imaging and MR arthrography have a unique role in diagnosis of these pathologies, guiding the surgeon, arthroscopist, and referring clinician in their management of bony and soft tissue injury.

    2006-01-01

    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

    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.

    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.

    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.

    Assessments of cardiac and cardiovascular toxicity are prominent components of drug safety endeavors during drug development and clinical practice. Oncologic drugs bring several challenges to both domains. First, during drug development, it is necessary to adapt the ICH E14 "Thorough QT/QTc Study" because the cytotoxic nature of many oncologics precludes their being administered to healthy individuals. Second, appropriate benefit-risk assessments must be made by regulators: given the benefit these drugs provide in life-threatening illnesses, a greater degree of risk may be acceptable when granting marketing authorization than for drugs for less severe indications. Third, considerable clinical consideration is needed for patients who are receiving and have finished receiving pharmacotherapy. Paradoxically, although such therapy has proved very successful in many cases, with disease states going into remission and patients living for many years after cessation of treatment, cardiotoxicities can manifest themselves relatively soon or up to a decade later. Oncologic drugs have been associated with various off-target cardiovascular responses, including cardiomyopathy leading to heart failure, cardiac dysrhythmias, thromboembolic events, and hypertension. Follow-up attention and care are, therefore, critical. This article reviews the process of benefit-risk estimation, provides an overview of nonclinical and preapproval clinical assessment of cardiovascular safety of oncology drugs, and discusses strategies for monitoring and management of patients receiving drugs with known cardiotoxicity risk. These measures include cardiac function monitoring, limitation of chemotherapy dose, use of anthracycline analogs and cardioprotectants, and early detection of myocardial cell injury using biomarkers.

  16. Selenistasis: Epistatic Effects of Selenium on Cardiovascular Phenotype

    Directory of Open Access Journals (Sweden)

    Joseph Loscalzo

    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.

    Favaro, A; Santonastaso, P

    2000-08-01

    Recent reports have postulated the existence of two different types of self-injurious behavior: impulsive and compulsive. The aim of the present study is to analyze the dimensionality of self-injurious behavior and to study the link between self-injurious behavior and clinical features in anorexia nervosa. The study involved 236 consecutive patients with anorexia nervosa, diagnosed by DSM-IV criteria. Subjects were evaluated by means of a semistructured interview and self-reported questionnaires, such as the Eating Disorders Inventory and Hopkins Symptom Checklist. A principal component analysis was used to study the dimensionality of different types of self-injurious behavior, including purging. Our findings confirm the distinction between impulsive and compulsive self-injurious behavior. The dimensions appear to be represented as a continuum in both the anorexia nervosa diagnostic subgroups. A third distinct dimension emerged that included self-induced vomiting and laxative/diuretics abuse. Childhood sexual abuse and anxiety significantly predict the presence of impulsive self-injury, whereas obsessionality and age predict compulsive self-injury. The coexistence of a positive score on both dimensions of self-injurious behavior was the strongest predictor of treatment dropout. The present study highlights the importance of self-injurious behavior; it should be given due consideration in future outcome studies on anorexia nervosa PMID:10972574

    In a prospective study 1085 rugby players and their injuries were recorded in the 1979 playing season. The age, grade, position, fitness and ground conditions did not affect the injury pattern. The majority of injuries were insignificant requiring no hospital follow up. The tackle accounted for 44 percent of all injuries. Set play does not contribute significantly to the number of injuries. The head and neck was the most frequently involved site, followed by the lower limbs. Foul play was implicated in 15 percent of all injuries. More stringent refereeing and coaching of the tackle could aid in reducing the number and severity of rugby injuries. PMID:6950267

    Currently a large proportion of patients with severe burn injuries survive. This gives increasing challenges also for psychological recovery after the trauma. More than half of burn patients have mental disorders already before the burn injury but also patients who previously had no mental disorders may suffer from them. Some of the hospitalize burn patients have injuries due to suicidal attempts. Only a small proportion of burn patients receive appropriate psychiatric care although psychosocial interventions specifically planned for burn victims exist. More frequent screening of symtoms of mental disorders and psychiatric consultation, also after acute care in hospital, could lead to better management of post-burn psychiatric care as well as better management of the burn treatment and rehabilitation itself.

    2014-10-01

    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.

    2012-03-01

    The predominant pattern of cardiovascular diseases in sub-Saharan Africa is that of poverty-related conditions (rheumatic heart valve disease, untreated congenital heart disease, tuberculous pericarditis) and diseases of unclear aetiology with a higher prevalence in this part of the world (peripartum cardiomyopathy, endomyocardial fibrosis). However, the prevalence of the traditional risk factors for cardiovascular diseases such as hypertension and marked obesity is high in a number of sub-Saharan settings, although they vary considerably among countries, urban/rural locations and specific subpopulations. In urban settings, hypertensive heart disease with systolic and diastolic function contributes substantially to morbidity. Awareness of the general public and health workers about the burden of cardiovascular diseases in women must be increased, and risk factor control programmes must be included in the health research agenda on the African continent. Improvement in health services with coordination of maternal health services and non-communicable diseases is also needed. This review focuses on the current knowledge of cardiovascular healthcare of women in sub-Saharan Africa, particularly their propensity for various forms of heart disease, access to healthcare, treatment received within the respective healthcare system, response to therapy and mortality. It highlights the gaps in knowledge and the paucity of data in most of these aspects. PMID:22350029

  12. Cardiovascular calcification. An inflammatory disease

    International Nuclear Information System (INIS)

    Cardiovascular calcification is an independent risk factor for cardiovascular morbidity and mortality. This disease of dysregulated metabolism is no longer viewed as a passive degenerative disease, but instead as an active process triggered by pro-inflammatory cues. Furthermore, a positive feedback loop of calcification and inflammation is hypothesized to drive disease progression in arterial calcification. Both calcific aortic valve disease and atherosclerotic arterial calcification may possess similar underlying mechanisms. Early histopathological studies first highlighted the contribution of inflammation to cardiovascular calcification by demonstrating the accumulation of macrophages and T lymphocytes in 'early' lesions within the aortic valves and arteries. A series of in vitro work followed, which gave a mechanistic insight into the stimulation of smooth muscle cells to undergo osteogenic differentiation and mineralization. The emergence of novel technology, in the form of animal models and more recently molecular imaging, has enabled accelerated progression of this field, by providing strong evidence regarding the concept of this disorder as an inflammatory disease. Although there are still gaps in our knowledge of the mechanisms behind this disorder, this review discusses the various studies that have helped form the concept of the inflammation-dependent cardiovascular calcification paradigm.

    Full Text Available BACKGROUND: To find out the prevalence of ‘all’ injuries, its nature, outcome and sources of treatment among rural population of Pondicherry. METHODS: It was a triangulated study of quantitative (survey and qualitative (Focus Group Discussion, FGD methods. The trained second year medical undergraduate students paid house visits to all houses in five feasibly selected villages of our field practice area. The students interviewed the housewife and obtained information for all injuries for each family member in last one year and its sources of treatment. We could obtain information for 1,613 (96.7% households. Post-survey, FGDs were undertaken to explore the various traditional treatments for the common injuries. The data was entered and analyzed using Epi_info 6.04d software package. RESULTS: Overall, the prevalence of all injury among all age groups was 30.6% in last one year. Injuries were significantly more after 18 years of age and among men (p<0.001. About 99.2% injuries reported were accidental and majority (58.2% went to government doctor for treatment. Most common causes of injuries were fall on the ground from height or due to slip (7.4%, road traffic accidents (5.6%, agriculture related injuries (5% and bites by scorpion/insects/snakes/dogs (4.1%. FGDs explored some potentially harmful traditional remedial measures at village level such as application of mud or cow dung on the injury and burning the site of thorn prick on foot sole. CONCLUSIONS: Considering the high prevalence of all injuries related to road traffic accidents, fall from height and agriculture work related injuries across all age groups, especially among men and some potentially harmful traditional treatments, an intervention in the form of targeted injury prevention program for different age and sex group, focusing health education efforts based on local epidemiology and behavioral practices is needed.

    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.

  2. Cardiovascular adverse effects of phenytoin.

    2016-05-01

    Phenytoin is an established drug in the treatment of acute repetitive seizures and status epilepticus. One of its main advantages over benzodiazepines is the less sedative effect. However, the possibility of cardiovascular adverse effects with the intravenous use of phenytoin cause a reluctance to its usage, and this has lead to a search for safer anticonvulsant drugs. In this study, we aimed to review the studies which evaluated the safety of phenytoin with respect to cardiovascular adverse effects. The original clinical trials and case reports listed in PUBMED in English language between the years of 1946-2014 were evaluated. As the key words, "phenytoin, diphenylhydantoin, epilepsy, seizure, cardiac toxicity, asystole, arrhythmia, respiratory arrest, hypotension, death" were used. Thirty-two clinical trials and ten case reports were identified. In the case reports, a rapid infusion rate (>50 mg/min) of phenytoin appeared as the major cause of increased mortality. In contrast, no serious cardiovascular adverse effects leading to death were met in the clinical trials which applied the recommended infusion rate and dosages. An infusion rate of 50 mg/min was reported to be safe for young patients. For old patients and patients with a cardiovascular co-morbidity, a slower infusion rate was recommended with a careful follow-up of heart rhythm and blood pressure. No cardiovascular adverse effect was reported in oral phenytoin overdoses except one case with a very high serum phenytoin level and hypoalbuminemia. Phenytoin is an effective and well tolerated drug in the treatment of epilepsy. Intravenous phenytoin is safe when given at recommended infusion rates and doses. PMID:26645393

    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.

    Milagros Lisset León Regal

    2016-06-01

    Full Text Available Background: there are no studies that confirm the association between cardiovascular hyperreactivity and the risk of cardiovascular morbidity. Objective: to determine the association between cardiovascular hyperreactivity and the risk of cardiovascular morbidity in normotensive individuals. Methods: a cross-sectional, correlational study was conducted. The universe consisted of the population aged 15 to 74 years in Cienfuegos municipality; the sample included 644 people. The variables were: sex, skin color, age, total cholesterol, HDL cholesterol, fasting blood glucose, smoking, baseline systolic blood pressure, cardiovascular reactivity, and risk of cardiovascular morbidity. The risk of cardiovascular morbidity was calculated by applying the Framingham Risk Functions. The Pearson’s Chi-square test and the prevalence ratio were used with a 95 % confidence interval. The direction of the relationship between cardiovascular reactivity, age, and systolic blood pressure was analyzed considering the Eta value. Results: the prevalence of cardiovascular hyperreactivity was higher among people aged 65 to 74 years and males. A higher risk of cardiovascular morbidity was observed in cardiovascular hyperreactive individuals. There is an association between non-optimal systolic blood pressure, increasing age, and high risk of cardiovascular morbidity in cardiovascular hyperreactive people. Conclusions: the risk of cardiovascular morbidity is higher in cardiovascular hyperreactive individuals than in normoreactive people. Age and systolic blood pressure showed greater association with high risk of cardiovascular morbidity.

  6. Missile injuries of the brain

    International Nuclear Information System (INIS)

    Data was analyzed relating to a consecutive series of 16 patients of penetrating brain injuries received at forward defense lines. Characteristics studied were the cause of injury, level of consciousness and various neurological deficits presented on initial examination, CT scan findings, the surgical procedures performed and the final outcome after one year of follow-up. One out of 16 patients, died due to severe associated injuries to abdominal viscera and major vessels. Meningitis occurred in one patient during the immediate postoperative period. All patients with motor weakness speech deficits and incontinence showed significant improvement. Hearing loss of one ear persisted in one patient. Two patients developed delayed onset seizures. It is concluded that, patients with penetrating brain injuries should be evacuated to the tertiary care neurosurgical centres as soon as possible. In operation only obviously necrotic brain and easily accessible metal and bone pieces should be removed. There is no need to explore the normal brain as it would only result in increased neurological deficits. The patients with such injuries should receive broad-spectrum antibiotics to prevent the infective complications. (author)

    Full Text Available Background: Although there have been significant advances in the management of traumatic brain injury (TBI, associated severe injuries, in particular chest injuries, remain a major challenge. This paper analyses the contribution of chest injuries to the outcome of head injuries in the University of Nigeria Teaching Hospital (UNTH and the Memfys Hospital for Neurosurgery (MHN in Enugu, Nigeria. Materials and Methods: This is a retrospective review of the medical records, operative notes, and radiological findings of all patients admitted for head injury who had associated significant chest injuries in the MHN from 2002 to 2009 and the UNTH between 2007 and 2010. Patients with only head injury and other extracranial injury not affecting the chest were excluded. Patients who were inadequately investigated were also excluded. Results: Nineteen patients from the MHN and 11 patients from the UNTH were analyzed. Ages ranged from 9 to 65 years and the male:female ratio was 3:1. Injuries were most common between 30 and 50 years and road traffic accident accounted for 60%. Barotrauma from ventilation was documented in 2 patients. The commonest types of intrathoracic injuries are pneumothorax and hemothorax. Chest wall injuries are more common but carry less morbidity and mortality. Only 20% of patients presented within 48 hours of injury. Management of the associated chest trauma commenced in the referring hospitals only in 26.4% of the patients. All patients with hemo-pneumothorax had tube thoracostomy as did 96% of patients with pneumothorax. 10% of patients with haemothorax needed thoracotomy. Mortality is 43%, which is higher than for patients with only TBI with comparable Glasgow coma scale. Outcome is influenced by the time to admission and the GCS on admission. Conclusion: Associated chest injuries result in higher mortality from head injuries. This association is more likely in the young and more productive. All patients presenting with head and

    Full Text Available Iron is the second most abundant metal in the Earth’s crust. Despite being present in trace amounts, it is an essential trace element for the human body, although it can also be toxic due to oxidative stress generation by the Fenton reaction, causing organic biomolecule oxidation. This process is the basis of numerous pathologies, including cardiovascular diseases (CVD. The relationship between iron and cardiovascular disease was proposed in 1981 by Jerome Sullivan. Since then, numerous epidemiological studies have been conducted to test this hypothesis. The aim of this review is to present the main findings of the chief epidemiological studies published during the last 32 years, since Sullivan formulated his iron hypothesis, suggesting that this element might act as a risk factor for cardiovascular disease. We have analyzed 55 studies, of which 27 supported the iron hypothesis, 20 found no evidence to support it and eight were contrary to the iron hypothesis. Our results suggest that there is not a high level of evidence which supports the hypothesis that the iron may be associated with CVD. Despite the large number of studies published to date, the role of iron in cardiovascular disease still generates a fair amount of debate, due to a marked disparity in results.

  13. The altered complexity of cardiovascular regulation in depressed patients

    International Nuclear Information System (INIS)

    Major depressive disorders (MDD) are associated with an increased risk for cardiovascular morbidity and mortality. Even if it is known that MDD are accompanied by an autonomic dysbalance with increased sympathetic and/or reduced parasympathetic activity, to date only limited information is available about the degree and complexity of cardiovascular regulation. The aim of this study was to investigate the influence of MDD on the autonomous nervous system and cardiovascular complexity by means of linear and nonlinear indices from heart rate and blood pressure variability (HRV, BPV). From 57 non-medicated patients and 57 matched healthy controls with respect to age and gender HRV and BPV in time and frequency domain, symbolic dynamics, compression entropy, multiscale entropy, detrended fluctuation analysis, Poincaré plot analysis and baroreflex sensitivity were analysed from 30 min short-term recordings. Complexity indices from nonlinear dynamics demonstrated considerable changes in autonomous regulation due to MDD. For the first time we could show that non-medicated depressed patients who were matched with respect to age and gender reveal a significantly changed short-term as well as long-term complexity of cardiovascular regulation. These results suggest substantial changes in autonomic control probably due to a change of interactions between different physiological control loops in MDD

  14. 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 retrospective longitudinal study aims to describe reported Taekwondo injuries and to examine associations between competitor experience level, age and gender, and the type, location, and mechanism of injury sustained. Additionally, we examined whether recent rule changes concerning increased point value of head shots in adult Taekwondo competition had affected injury incidence.This study was a summation of 9 years of data of competition injury reports, which included 904 injury reports spanning 58 individual competitions. The data was collected on standardized injury reports at time of injury during competition. Care was provided to the athletes, but the type of care provided was not included in the study. Participants included athletes injured during competition who sought care by the health care team, and for whom an injury report was filled out. The data analysis was performed at the Canadian Memorial Chiropractic College.The three most common locations of presenting injury were the head (19%), foot (16%), and thigh (9%). The most common mechanism of presenting injury was found to be a defensive kick (44%), followed by an offensive kick (35%). The most commonly diagnosed injuries were contusions (36%), sprains (19%), and strains (15%). Coloured belts had a higher incidence of contusions, while black belts sustained more joint irritation injuries. Black belts were more likely to suffer multiple injuries. Colored belts suffered more injuries while receiving a kick, while black belts had a larger influence of past history of injury. We found no significant difference in location or type of injury when comparing pre versus post rule change. The most common locations of injury are head, foot, and thigh respectively, and are areas for concern when considering preventative measures. Colour belt competitors are more likely to sustain contusions, which the authors believe is due to more aggressive tactics and lack of control. Those more likely to be injured tend to

    2015-01-01

    Neurological injury, such as spinal cord injury, has a secondary injury associated with it. The secondary injury results from the biological cascade after the primary injury and affects previous uninjured, healthy tissue. Therefore, the mitigation of such a cascade would benefit patients suffering a primary injury and allow the body to recover more quickly. Unfortunately, the delivery of effective therapeutics is quite limited. Due to the inefficient delivery of therapeutic drugs, nanoparticles have become a major field of exploration for medical applications. Based on their material properties, they can help treat disease by delivering drugs to specific tissues, enhancing detection methods, or a mixture of both. Incorporating nanomedicine into the treatment of neuronal injury and disease would likely push nanomedicine into a new light. This review highlights the various pathological issues involved in secondary spinal cord injury, current treatment options, and the improvements that could be made using a nanomedical approach.

    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.

    Objective Motor vehicle crash (MVC)-related spinal injuries result in significant morbidity and mortality in children. The objective was to identify MVC-related injury causation scenarios for spinal injuries in restrained children. Methods This was a case series of occupants in MVCs from the Crash Injury Research and Engineering Network (CIREN) data set. Occupants aged 0–17 years old with at least one Abbreviated Injury Scale (AIS) 2+ severity spinal injury in vehicles model year 1990+ that did not experience a rollover were included. Unrestrained occupants, those not using the shoulder portion of the belt restraint, and those with child restraint gross misuse were excluded. Occupants with preexisting comorbidities contributing to spinal injury and occupants with limited injury information were also excluded. A multidisciplinary team retrospectively reviewed each case to determine injury causation scenarios (ICSs). Crash conditions, occupant and restraint characteristics, and injuries were qualitatively summarized. Results Fifty-nine cases met the study inclusion criteria and 17 were excluded. The 42 occupants included sustained 97 distinct AIS 2+ spinal injuries (27 cervical, 22 thoracic, and 48 lumbar; 80 AIS-2, 15 AIS-3, 1 AIS-5, and 1 AIS-6), with fracture as the most common injury type (80%). Spinal-injured occupants were most frequently in passenger cars (64%), and crash direction was most often frontal (62%). Mean delta-V was 51.3 km/h ± 19.4 km/h. The average occupant age was 12.4 ± 5.3 years old, and 48% were 16- to 17-year-olds. Thirty-six percent were right front passengers and 26% were drivers. Most occupants were lap and shoulder belt restrained (88%). Non-spinal AIS 2+ injuries included those of the lower extremity and pelvis (n = 56), head (n = 43), abdomen (n = 39), and thorax (n = 36). Spinal injury causation was typically due to flexion or lateral bending over the lap and or shoulder belt or child restraint harness, compression by occupant

  1. Role of the hypothalamic arcuate nucleus in cardiovascular regulation.

    Recently the hypothalamic arcuate nucleus (Arc) has been implicated in cardiovascular regulation. Both pressor and depressor responses can be elicited by the chemical stimulation of the Arc. The direction of cardiovascular responses (increase or decrease) elicited from the Arc depends on the baseline blood pressure. The pressor responses are mediated via increase in sympathetic nerve activity and involve activation of the spinal ionotropic glutamate receptors. Arc-stimulation elicits tachycardic responses which are mediated via inhibition of vagal input and excitation of sympathetic input to the heart. The pathways within the brain mediating the pressor and tachycardic responses elicited from the Arc have not been delineated. The depressor responses to the Arc-stimulation are mediated via the hypothalamic paraventricular nucleus (PVN). Gamma aminobutyric acid type A receptors, neuropeptide Y1 receptors, and opiate receptors in the PVN mediate the depressor responses elicited from the Arc. Some circulating hormones (e.g., leptin and insulin) may reach the Arc via the leaky blood-brain barrier and elicit their cardiovascular effects. Although the Arc is involved in mediating the cardiovascular responses to intravenously injected angiotensin II and angiotensin-(1-12), these effects may not be due to leakage of these peptides across the blood-brain barrier in the Arc; instead, circulating angiotensins may act on neurons in the SFO and mediate cardiovascular actions via the projections of SFO neurons to the Arc. Cardiovascular responses elicited by acupuncture have been reported to be mediated by direct and indirect projections of the Arc to the RVLM. PMID:23260431

    Akanksha Srivastava

    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

    Tetramethylpyrazine (TMP), a pharmacologically active component isolated from the rhizome of the Chinese herb Rhizoma Chuanxiong (Chuanxiong), has been clinically used in China and Southeast Asian countries for the prevention and treatment of cardiovascular diseases (CVDs) for about fifty years. The pharmacological effects of TMP on the cardiovascular system have attracted great interest. Emerging experimental studies and clinical trials have demonstrated that TMP prevents atherosclerosis as well as ischemia-reperfusion injury. The cardioprotective effects of TMP are mainly related to its antioxidant, anti-inflammatory, or calcium-homeostasis effects. This review focuses on the roles and mechanisms of action of TMP in the cardiovascular system and provides a novel perspective on TMP's clinical use. PMID:27314011

    Type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD) and the cardiovascular effect of antidiabetic drugs are today critical medical issues, with the prevalence of T2DM in particular showing a steep increase worldwide, mainly due to unhealthy lifestyle habits. T2DM in association with obesity and other cardiovascular risk factors, results in the development of CVD, the leading cause of morbidity and mortality in patients with T2DM. Thus, treatment of T2DM is an individualized and complex challenge in which targeting cardiovascular risk factors is an important component in the decision making. Given the cardiovascular adverse events associated with rosiglitazone, both the Food and Drug Administration and the European Medicines Agency currently require the demonstration of cardiovascular safety of new antidiabetic drugs. Consequently, clinical trials to guarantee their cardiovascular safety are now obligatory. This review aims to summarize the available evidence on the cardiovascular effects and safety of the major drugs used in T2DM treatment and also to provide an overview of upcoming and ongoing clinical trials in this field. Our belief is that this review will be of substantial assistance to all medical doctors who are treating diabetic patients, namely primary care physicians, internal medicine doctors, endocrinologists, diabetologists and less well experienced personnel such as young doctors in training.

    Blunt renal trauma is the third most common injury in abdominal trauma following splenic and hepatic injuries, respectively. In the majority, such injuries are associated with other abdominal organ injuries. As urological injuries are not usually life-threatening, and clinical signs and symptoms are non-specific, diagnosis is often delayed. We present a practical approach to the diagnosis and management of these injuries based on our experience in a busy inner city trauma hospital with a review of the current evidence-based practice. Diagnostic imaging signs are illustrated.

    Every year in the United States, millions of individuals incur ischemic brain injury from stroke, cardiac arrest, or traumatic brain injury. These acquired brain injuries can lead to death or long-term neurologic and neuropsychological impairments. The mechanisms of ischemic and traumatic brain injury that lead to these deficiencies result from a complex interplay of interdependent molecular pathways, including excitotoxicity, acidotoxicity, ionic imbalance, oxidative stress, inflammation, and apoptosis. This article reviews several mechanisms of brain injury and discusses recent developments. Although much is known from animal models of injury, it has been difficult to translate these effects to humans. PMID:27521191

    @@ The ankle and foot are the most common sites for athletic injuries.[1]Midfoot,or Lisfranc,injuries are the second most common foot injury and have a high in cidence in particular sports.They account for 4% of all football injuries per year,occurring frequently in linemen.[2]They are also common in equestrians,surfers,and windsurfers.[2]Lisfranc injuries are often misdiagnosed and if not treated properly can have lingering symptoms.It is estimated that Lisfranc joint injuries occur in 1 in every 55,000 persons every year.[3,4

  14. Nuclear imaging of cardiovascular disease

    International Nuclear Information System (INIS)

    Nuclear imaging methods provide noninvasive indexes of myocardial function, perfusion, and metabolism and are well accepted in clinical cardiology. Advances in prevention and treatment of cardiac disease have resulted in decreasing cardiovascular mortality in industrialized nations. The improvement in therapeutic options has increased the demand for diagnostic tests that might guide clinical decision making. Information beyond the pure anatomic characterization of coronary stenoses is required. Nuclear imaging can be used for early detection and monitoring of the severity and extent of disease. The prognostic potential of such functional testing is being increasingly appreciated and used to guide therapy, thereby resulting in improvement of the quality and cost-effectiveness of the workup of patients with cardiovascular disease. Extensive clinical validation has resulted in growing acceptance of these techniques. Furthermore, ongoing improvement of imaging techniques and development of new radiopharmaceuticals will pave the way for disease-specific, molecular-targeted cardiac imaging in the future. (orig.)

  15. Cardiovascular Prevention of Cognitive Decline

    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.

    Many, but not all people experience diminished health, performance and well-being as a function of exposure to stress. However, the underlying neurophysiological processes which characterize hardy or resilient people are not well understood. This study examines psychological hardiness and several indicators of cardiovascular health, including body mass index (BMI) and blood cholesterol markers in a sample of 338 middle-aged adults enrolled in a national security education program. Hierarchical regression analyses reveal that after controlling for the influence of age and sex, high hardiness is related to higher HDL - high density lipoprotein and less body fat (BMI). Lower hardiness is associated with greater total cholesterol to HDL ratio, a cardiovascular disease risk factor. These results suggest that psychological hardiness confers resilience in part through an influence on cholesterol production and metabolism. PMID:26652199

  17. Cardiovascular stress of photochemotherapy (PUVA)

    International Nuclear Information System (INIS)

    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

  18. Imaging of sports injuries in children and adolescents

    International Nuclear Information System (INIS)

    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
