To assess various factors associated with anterior S-T segment depression during acute inferior myocardial infarction, 47 consecutive patients with electrocardiographic evidence of a first transmural inferior infarction were studied prospectively with radionuclide ventriculography an average of 7.3 hours (range 2.9 to 15.3) after the onset of symptoms. Thirty-nine patients (Group I) had anterior S-T depression in the initial electrocardiogram and 8 (Group II) did not have such reciprocal changes. There was no difference between the two groups in left ventricular end-diastolic or end-diastolic volume index or left ventricular ejection fraction. Stroke volume index was greater in Group I than in Group II. There were no group differences in left ventricular total or regional wall motion scores. A weak correlation existed between the quantities (mV) or inferior S-T segment elevation and reciprocal S-T depression. No relation between anterior S-T segment depression and the left ventricular end-diastolic volume index could be demonstrated; the extent of left ventricular apical and right ventricular wall motion abnormalities, both frequently associated with inferior infarction, did not correlate with the quantity of anterior S-T depression. These data show that anterior S-T segment depression occurs commonly during the early evolution of transmural inferior infarction, is not generally a marker of functionally significant anterior ischemia and cannot be used to predict left ventricular function in individual patients. Anterior S-T segment depression may be determined by reciprocal mechanisms

Psychosocial stress and depression are established risk factors for cardiovascular disease and a relationship to periodontitis has been suggested. We studied symptoms of depression and their relation to myocardial infarction and periodontitis. In a Swedish case-control study, 805 patients, stress at home and work, and symptoms of depression (Montgomery Åsberg Depression Scale). A Montgomery Åsberg Depression Scale score ⩾13 was considered clinically relevant. A family history of cardiovascular disease, smoking and divorce was more frequent among patients than controls. Patients had more symptoms of depression than controls (14 vs 7%; pless anti-depressive treatment (16 vs 42%; pless anti-depressive treatment. A relationship between depression and periodontitis could not be confirmed.

In this study, we investigated the relationship between tryptophan-5-hydroxytryptamine metabolism, depressive disorder, and gastrointestinal dysfunction in rats after myocardial infarction. Our goal was to elucidate the physiopathologic bases of somatic/psychiatric depression symptoms after myocardial infarction. A myocardial infarction model was established by permanent occlusion of the left anterior descending coronary artery. Depression-like behavior was evaluated using the sucrose preference test, open field test, and forced swim test. Gastric retention and intestinal transit were detected using the carbon powder labeling method. Immunohistochemical staining was used to detect indoleamine 2,3-dioxygenase expression in the hippocampus and ileum. High-performance liquid chromatography with fluorescence and ultraviolet detection determined the levels of 5-hydroxytryptamine, its precursor tryptophan, and its metabolite 5-hydroxyindoleacetic acid in the hippocampus, distal ileum, and peripheral blood. All data were analyzed using one-way analyses of variance. Three weeks after arterial occlusion, rats in the model group began to exhibit depression-like symptoms. For example, the rate of sucrose consumption was reduced, the total and central distance traveled in the open field test were reduced, and immobility time was increased, while swimming, struggling and latency to immobility were decreased in the forced swim test. Moreover, the gastric retention rate and gastrointestinal transit rate were increased in the model group. Expression of indoleamine 2,3-dioxygenase was increased in the hippocampus and ileum, whereas 5-hydroxytryptamine metabolism was decreased, resulting in lower 5-hydroxytryptamine and 5-hydroxyindoleacetic acid levels in the hippocampus and higher levels in the ileum. Depressive disorder and gastrointestinal dysfunction after myocardial infarction involve abnormal tryptophan-5-hydroxytryptamine metabolism, which may explain the somatic, cognitive

Patients with a depressive disorder after myocardial infarction (MI) have a significantly increased risk of major cardiac events. The Myocardial INfarction and Depression-Intervention Trial (MIND-IT) investigates whether antidepressive treatment can improve the cardiac prognosis for these patients. The rationale and outline of the study are described. In this multicenter randomized clinical trial, 2140 patients admitted for MI are screened for depressive symptoms with a questionnaire 0, 3, 6, 9, and 12 months after MI. Patients with symptoms undergo a standardized psychiatric interview. Those with a post-MI depressive episode are randomized to intervention (ie, antidepressive treatment; n = 190) or care-as-usual (CAU; n = 130). In the intervention arm, the research diagnosis is to be confirmed by a psychiatrist. First-choice treatment consists of placebo-controlled treatment with mirtazapine. In case of refusal or nonresponse, alternative open treatment with citalopram is offered. In the CAU arm, the patient is not informed about the research diagnosis. Psychiatric treatment outside the study is recorded, but no treatment is offered. Both arms are followed for end points (cardiac death or hospital admission for MI, unstable angina, heart failure, or ventricular tachyarrhythmia) during an average period of 27 months. Analysis is on an intention-to-treat basis. The MIND-IT study will show whether treatment of post-MI depression can improve cardiac prognosis.

MRI studies were carried out on 69 patients with multiple lacunar infarcts: 32 had hyperactive-type delirium and the other 37 were non-delirious controls. Between the two groups, there were no statistically significant differences in mean age and sex distribution. In the corona radiata and basal ganglia, the number of infarcts did not differ between the two groups. However, the extent of thalamic infarcts and periventricular hyperintensity (PVH), the maximal width of the third ventricle and Evans' ratio among the delirious patients were significantly larger than those in the controls. In conclusion, thalamic lesions and diffuse advanced PVH may have an intimate correlation in the development of hyperactive-type delirium in patients with multiple lacunar infarcts. (author)

1993-01-01

We examined the relationship between pre-senile, senile depressive states and silent cerebral infarction (SCI) using magnetic resonance imaging (MRI). The diagnostic criteria of major depression according to DSM-3-R was used to diagnose. Patients in whom stroke had occurred or who had local neurologic symptoms were not included. About half of the patients with depressive states of pre-senile onset and most of the patients with those of senile onset had SCI, were considered to be organic-depressive states complicated with SCI. Because patients with depressive states with SCI are at high risk of occurrence of stroke, we designated this condition 'pre-stroke depression', and classified it with endogenous depression. At this time, it is important to begin therapy for cerebrovascular disease. (author)

Ample evidence identifies strong links between major depressive disorder (MDD) and both risk of ischemic or coronary heart disease (CHD) and resultant morbidity and mortality. The molecular mechanistic bases of these linkages are poorly defined. Systemic factors linked to MDD, including vascular dysfunction, atherosclerosis, obesity and diabetes, together with associated behavioral changes, all elevate CHD risk. Nonetheless, experimental evidence indicates the myocardium is also directly modified in depression, independently of these factors, impairing infarct tolerance and cardioprotection. It may be that MDD effectively breaks the heart's intrinsic defense mechanisms. Four extrinsic processes are implicated in this psycho-cardiac coupling, presenting potential targets for therapeutic intervention if causally involved: sympathetic over-activity vs. vagal under-activity, together with hypothalamic-pituitary-adrenal (HPA) axis and immuno-inflammatory dysfunctions. However, direct evidence of their involvement remains limited, and whether targeting these upstream mediators is effective (or practical) in limiting the cardiac consequences of MDD is unknown. Detailing myocardial phenotype in MDD can also inform approaches to cardioprotection, yet cardiac molecular changes are similarly ill defined. Studies support myocardial sensitization to ischemic insult in models of MDD, including worsened oxidative and nitrosative damage, apoptosis (with altered Bcl-2 family expression) and infarction. Moreover, depression may de-sensitize hearts to protective conditioning stimuli. The mechanistic underpinnings of these changes await delineation. Such information not only advances our fundamental understanding of psychological determinants of health, but also better informs management of the cardiac consequences of MDD and implementing cardioprotection in this cohort.

Significance of exercise-induced ST segment depression in patients with myocardial infarction involving the left circumflex artery. Evaluation by exercise thallium-201 myocardial single photon emission computed tomography

International Nuclear Information System (INIS)

Koitabashi, Norimichi; Toyama, Takuji; Hoshizaki, Hiroshi

2000-01-01

The significance of exercise-induced ST segment depression in patients with left circumflex artery involvement was investigated by comparing exercise electrocardiography with exercise thallium-201 single photon emission computed tomography (Tl-SPECT) and the wall motion estimated by left ventriculography. Tl-SPECT and exercise electrocardiography were simultaneously performed in 51 patients with left circumflex artery involvement (angina pectoris 30, myocardial infarction 21). In patients with myocardial infarction, exercise-induced ST depression was frequently found in the V 2 , V 3 and V 4 leads. In patients with angina pectoris, ST depression was frequently found in the II, III, aV F , V 5 and V 6 leads. There was no obvious difference in the leads of ST depression in patients with myocardial infarction with ischemia and without ischemia on Tl-SPECT images. In patients with myocardial infarction, the lateral wall motion of the infarcted area evaluated by left ventriculography was more significantly impaired in the patients with ST depression than without ST depression (p<0.01). Exercise-induced ST depression in the precordial leads possibly reflects wall motion abnormality rather than ischemia in the lateral infarcted myocardium. (author)

The clinical significance of MRI in thrombotic multiple cerebral infarction was examined in 9 patients having recent lacunar stroke. Recent infarct was identified on Gd-enhanced MRI in 4 patients. For patients multiple small infarction, Gd-enhanced MRI made it possible to differentiate recent from other lesions. To clarify the significance of periventricular high intensity lesion (PVH) on T2-weighted MRI, hemodynamic and neuropsychologic examinations were carried out in 41 patients with multiple cerebral infarction. All the patients had PVH, which was classified into three grades as follows: grade I (n=16) showing only a thin high intensity band along the body of lateral ventricles; grade 2 (n=15) showing a definite high intensity area around the lateral ventricles; grade 3 (n=10) showing diffuse thick and irregular foci around the whole ventricle. In these patients, rCBF was measured by 133 Xe inhalation methods. Initial slope index was significantly higher in patients with grade 3 than those with grade I. Mini-mental state test score was significantly higher in patients with grade l than those with grade 2 and 3. Progression of PVH may be related with the reduction of the cerebral circulation and mental function in cases of multiple cerebral infarction. Ischemic and hemorrhagic lesions can be distinguished by MRI, because old intracerebral hemorrhage appear as hypointensity areas with or without hyperintensity area on T2w images. In 92 patients with multiple infarction, MRI was used to evaluate the incidence and distribution of coexisting old intracerebral hemorrhage. Old hemorrhage were found in 15 patients (16.3%). locating the site where hypertensive hemorrhage commonly occurred. High-field MRI is useful for assessing the coexistence of hemorrhage in hypertensive patients with multiple cerebral infarction. (N.K.)

The clinical significance of anterior precordial ST segment depression during acute inferior myocardial infarction was evaluated in 67 consecutive patients early after onset of symptoms with gated blood pool scans, thallium-201 perfusion images, and 12-lead ECGs. Patients with anterior ST depression (n = 33) had depressed mean values for left ventricular ejection fraction (54 +/- 2% [mean +/- S.E.M.] vs 59 +/- 2%; p = 0.02), cardiac index (3.1 +/- 0.2 vs 3.6 +/- 0.2 L/m2; p = 0.03), and ratio of systolic blood pressure to end-systolic volume (2.0 +/- 0.1 vs 2.5 +/- 0.3 mm Hg/ml; p = 0.04) compared to patients with no anterior ST depression (n = 34). Patients with anterior ST depression had (1) lower mean wall motion values for the inferior, apical, and inferior posterolateral segments (p less than 0.05) and (2) greater reductions in thallium-201 uptake in the inferior and posterolateral regions (p less than 0.05). However, anterior and septal (1) wall motion and (2) thallium-201 uptake were similar in patients with and without ST depression. Thus, anterior precordial ST segment depression in patients with acute inferior wall myocardial infarction represents more than a reciprocal electrical phenomenon. It identifies patients with more severe wall motion impairment and greater hypoperfusion of the inferior and adjacent segments. The poorer global left ventricular function in these patients is a result of more extensive inferior infarction and not of remote septal or anterior injury

Effect of myocardial infarction on the function and metabolism of the non-infarcted muscle

Rat hearts were infarcted in vivo by ligation of the left ventricular coronary artery. After one or three weeks, the hearts were isolated and perfused in vitro. Despite the onset of hypertrophy, ventricular function was more depressed in the one- and three-week infarcted hearts than in acutely ligated hearts. These data suggested that the depressed mechanical function was due not only to the loss of viable tissue, but also to alterations occurring in the non-infarcted tissue. The inotropic response to extracellular calcium was depressed in infarcted hearts, such that the mechanical performance of the infarcted heart was likely to be limited by the availability of extracellular calcium under physiological conditions. No limitation in energy production was found as indicated by the maintenance of ATP levels, the creatine phosphate/creatine ratio and normal lactate concentrations in the infarcted hearts. Comparison of the rates of substrate oxidation with MVO 2 revealed that, in both the sham and infarcted hearts, substrate oxidation, as estimated by 14 CO 2 production, could not account for the observed MVO 2 . It was found that the rate of 14 CO 2 production from exogenous labeled palmitate underestimated the actual rate of fatty acid oxidation. This resulted from incomplete equilibration of added [ 14 C]-palmitate with the fatty acyl moieties present in acyl carnitine. However, the rate of 14 CO 2 production from exogenous palmitate was lower in the infarcted than sham hearts

Tomographic imaging of the brain was performed using a rotating slant hole collimator and [ 123 I]N-isopropyl p-iodoamphetamine (IMP) in normal subjects (n = 6) and patients with either Alzheimer's disease (n = 5) or multiple infarct dementia (n = 3). Four blinded observers were asked to make a diagnosis from the images. Normal subjects and patients with multiple infarct dementia were correctly identified. Alzheimer's disease was diagnosed in three of the five patients with this disease. One patient with early Alzheimer's disease was classified as normal by two of the four observers. Another patient with Alzheimer's disease had an asymmetric distribution of IMP and was incorrectly diagnosed as multiple infarct dementia by all four observers. Limited angle tomography of the cerebral distribution of 123 I appears to be a useful technique for the evaluation of demented patients

Background:Our previous studies have demonstrated that the levels of 5-hydroxytryptamine (5-HT) and 5-HT 2A receptor (5-HT2AR) in serum and platelet were associated with depression and myocardial infarction (MI),and pretreatment with ginseng fruit saponins (GFS) before MI and depression had an effect on the 5-HT system.In this study,the effects of GFS on the 5-HT system in the Sprague-Dawley (SD) rats with MI,depression,and MI + depression were evaluated.Methods:A total of eighty SD rats were allocated to four groups:MI,depression,MI + depression,and control groups (n =20 in each group).Each group included two subgroups (n =10 in each subgroup):Saline treatment subgroup and GFS treatment subgroup.The levels of5-HT,5-HT2AR,and serotonin transporter (SERT) were quantified in serum,platelet lysate,and brain tissue through the enzyme-linked immunosorbent assay method,respectively.Results:Compared with those in the saline treatment subgroups,the levels of 5-HT in serum and platelet lysate statistically significantly increased in the GFS treatment subgroups of MI,depression,and MI + depression groups (serum:all P =0.000;platelet lysate:P =0.002,0.000,0.000,respectively).However,the 5-HT levels in brain homogenate significantly decreased in the GFS treatment subgroups compared with those in the saline treatment subgroups in MI and depression groups (P =0.025 and 0.044 respectively),and no significant difference was observed between saline and GFS treatment subgroups in MI + depression group (P =0.663).Compared with that in GFS treatment subgroup of control group,the 5-HT2AR levels in the platelet lysate significantly decreased in GFS treatment subgroups of MI,depression,and MI + depression groups (all P=0.000).Compared to those in the saline treatment subgroups,the serum SERT levels significantly decreased in the GFS treatment subgroups in MI,depression,and MI + depression groups (P =0.009,0.038,and P=0.001,respectively),while the SERT levels ofplatelet lysate

We examined the relationship between pre-senile, senile depressive states and silent cerebral infarction (SCI) using magnetic resonance imaging (MRI). The diagnostic criteria of major depression according to DSM-3-R was used to diagnose. Patients in whom stroke had occurred or who had local neurologic symptoms were not included. About half of the patients with depressive states of pre-senile onset and most of the patients with those of senile onset had SCI, were considered to be organic-depressive states complicated with SCI. Because patients with depressive states with SCI are at high risk of occurrence of stroke, we designated this condition 'pre-stroke depression', and classified it with endogenous depression. At this time, it is important to begin therapy for cerebrovascular disease. (author).

Abstract Anxiety and depressive symptoms are associated with adverse cardiovascular events after an acute myocardial infarction (MI). However, most studies focusing on anxiety or depression have used rating scales or self-report methods rather than clinical diagnosis. This study aimed to investigate the association between psychiatrist-diagnosed psychiatric disorders and cardiovascular prognosis. We sampled data from the National Health Insurance Research Database; 1396 patients with MI were recruited as the study cohort and 13,960 patients without MI were recruited as the comparison cohort. Cox proportional hazard regression models were used to examine the effect of MI on the risk of anxiety and depressive disorders. During the first 2 years of follow-up, patients with MI exhibited a significantly higher risk of anxiety disorders (adjusted hazard ratio [HR] = 5.06, 95% confidence interval [CI]: 4.61–5.54) and depressive disorders (adjusted HR = 7.23, 95% CI: 4.88–10.88) than those without MI did. Greater risk for anxiety and depressive disorders was observed among women and patients aged 45 to 64 years following an acute MI. Patients with post-MI anxiety had a 9.37-fold (95% CI: 4.45–19.70) higher risk of recurrent MI than those without MI did after adjustment for age, sex, socioeconomic status, and comorbidities. This nationwide population-based cohort study provides evidence that MI increases the risk of anxiety and depressive disorders during the first 2 years post-MI, and post-MI anxiety disorders are associated with a higher risk of recurrent MI.

Full Text Available Predisposing factors for venous thrombosis can be identified in the majority of patients with established venous thromboembolism (VTE. However, an obvious precipitant may not be identified during the initial evaluation of such patients. In the present case, a 47-year-old female presented to the emergency department of our hospital after ingesting multiple drugs. She had no VTE-related risk factors or previous episodes, nor any family history of VTE. After admission to the intensive care unit sudden hypoxemia developed, and during the evaluation cerebral, renal, and splenic infarctions with pulmonary embolisms were diagnosed. However, the sources of the emboli could not be identified by transthoracic echocardiography or computed tomography angiography. Protein C deficiency was identified several days later. We recommend that hypercoagulable states be taken into consideration, especially when unexplained thromboembolic events develop in multiple or unusual venous sites.

The association between myocardial infarction (MI) and depression is well described. Yet, the underlying mechanisms are unclear and the contribution of psychological factors is uncertain. We aimed to determine the risk of recognized (RMI) and unrecognized (UMI) myocardial infections on depression, as both have a similar impact on cardiovascular health but differ in psychological epiphenomena. Participants of the Rotterdam Study, 1823 men aged ⩾55 years, were followed for the occurrence of depression. RMI and UMI were ascertained using electrocardiography and medical history at baseline. We determined the strength of the association of RMI and UMI with mortality, and we studied the relationship of RMI and UMI with depressive symptoms and the occurrence of major depression. The risk of mortality was similar in men with RMI [adjusted hazard ratio (aHR) 1.71, 95% confidence interval (CI) 1.45-2.03] and UMI (aHR 1.58, 95% CI 1.27-1.97). Men with RMI had on average [unstandardized regression coefficient (B) 1.14, 95% CI 0.07-2.21] higher scores for depressive symptoms. By contrast, we found no clear association between UMI and depressive symptoms (B 0.55, 95% CI -0.51 to 1.62) in men. Analysis including occurrence of major depression as the outcome were consistent with the pattern of association. The discrepant association of RMI and UMI with mortality compared to depression suggests that the psychological burden of having experienced an MI contributes to the long-term risk of depression.

Recent studies have identified paroxetine as a G protein-coupled receptor kinase-2 (GRK2 inhibitor capable of reversing cardiac dysfunction and remodeling in experimental models of acute myocardial infarction (AMI. We determine the clinical importance of paroxetine on cardiac functions in patients having AMI with depression (AMID in comparison with fluoxetine, an unrelated selective serotonin reuptake inhibitor that does not inhibit GRK2.Methods: Diagnosis of depression was based on the 17-item Hamilton Depression Scale and Self-rating Depression Scale in AMI patients after hospital admission. AMID patients were randomly assigned to paroxetine or fluoxetine for treatment of depression. Heart rate variability and cardiac function were evaluated. GRK2 protein levels were measured using peripheral lymphocytes and Western blot.Results: GRK2 expression in AMID patients was significantly higher than that in AMI patients without depression. In AMID patients, GRK2 levels were positively correlated with the 17-item Hamilton Depression Scale and the Self-rating Depression Scale scores, and negatively correlated with heart rate variability. Treatment of AMID patients with paroxetine significantly reduced the expression of GRK2, normalized the autonomic nervous system function, and improved cardiac performance. In contrast, fluoxetine normalized the autonomic nervous system but did not reduce the expression of

Cerebral air embolism is a rare cause of cerebral infarction. In cerebral air embolism, T2 star-weighted imaging shows numerous spotty hypointense signals. Previous reports have suggested that these signals represent air in the brain and are gradually diminished and absorbed. We experienced two cases of cerebral air embolism, and in one of them, we conducted an autopsy. Case 1 was a 76-year-old Japanese man with lung cancer and emphysema. A spasmodic cough induced massive cerebral and cardiac air embolisms and the patient died because of cerebral herniation. T2 star-weighted imaging of brain magnetic resonance imaging showed multiple spotty low signals. Brain autopsy showed numerous spotty hemorrhagic infarcts in the area of T2 star-weighted imaging signals. Case 2 was an 85-year-old Japanese man with emphysema who suffered from acute stroke. Similar spotty T2 star-weighted imaging signals were observed and remained unchanged 2 months after the onset. These findings indicate that T2 star-weighted imaging in cerebral air embolism partially represents micro-hemorrhagic infarction caused by air bubbles that have migrated into the brain.

Because depression and anxiety are typically studied in isolation, our purpose was to examine the relative importance of these overlapping emotional factors in predicting incident cardiovascular disease (CVD). We examined depression and anxiety screens, and their individual items, as predictors of incident hard CVD events, myocardial infarction, and stroke for 8 years in a diverse sample of 2041 older primary care patients initially free of CVD. At baseline, participants completed self-report depression and anxiety screens. Data regarding CVD events were obtained from an electronic medical record system and the Centers for Medicare and Medicaid Services analytic files. During follow-up, 683 (33%) experienced a CVD event. Cox proportional hazards models-adjusted for demographic and CVD risk factors-revealed that a positive anxiety screen, but not a positive depression screen, was associated with an increased risk of a hard CVD event in separate models (Years 0-3: anxiety hazard ratio [HR] = 1.54, 95% confidence interval [CI] = 1.21-1.96, p anxiety HR = 0.99, CI = 0.81-1.21), p = .93; depression HR = 1.10, CI = 0.88-1.36, p = .41), as well as when entered into the same model (Years 0-3: anxiety HR = 1.53, CI = 1.20-1.95, p anxiety HR = 0.99, CI = 0.80-1.21, p = .99; depression HR = 1.03, CI = 0.82-1.29, p = .82). Analyses examining individual items and secondary outcomes showed that the anxiety-CVD association was largely driven by the feeling anxious item and the myocardial infarction outcome. Anxiety, especially feeling anxious, is a unique risk factor for CVD events in older adults, independent of conventional risk factors and depression. Anxiety deserves increased attention as a potential factor relevant to CVD risk stratification and a potential target of CVD primary prevention efforts.

Full Text Available Background: Major depressive disorder is widely prevalent in post myocardial infarction (MI period. Various studies have reported a significant relationship between these two major disease states. Aim: To examine depression after MI and its socio-demographic variation. Methods: The study was a follow up study on patients of acute MI (n=50 attending cardiology outpatient department of the Assam Medical College Hospital in four to six weeks after the index event. Screening was done by the Primary Care Evaluation of Mental Disorders and diagnoses of major depressive disorder were established according to the text revision of the fourth edition of the Diagnostic and Statistical Manual for Mental Disorders criteria. Severity of the depression was assessed by the Beck Depression Inventory. Study populations were again reassessed after eight weeks from the index event. Statistical software packages like SPSS-20, XLSTAT, and Microsoft Office Access were used for analysis. Results: Twenty eight and 32% of the study subjects were depressed on their first and second visit respectively. Conclusion: Similar pattern of post MI depression is found in our state likewise in correlation to western and Indian studies which were conducted in different states. So we recommend vigilance from the clinician’s side while handling cases of MI.

We studied the association between mental ability as rated by Hasegawa's scale, the severity of hypertension, the severity of brain atrophy, and the severity of lesions in the cerebral white matter on magnetic resonance imaging in 34 patients with multiple cerebral infarcts but without obvious cortical lesions. Data were analyzed using multiple regression analysis. The patients having both marked brain atrophy and severe white matter lesions showed an impairment of mental ability. Brain atrophy was correlated with aging and the severity of white matter lesions. There was a significant positive correlation between the diastolic blood pressure and the severity of white matter lesions. These findings suggest that the white matter lesions in patients with multiple cerebral infarcts are correlated with brain atrophy and mental deterioration, and that uncontrolled hypertension is an important risk factor in exacerbating the lesions in the cerebral white matter.

Background:To evaluate whether serotonin (5-HT),5-HT2A receptor (5-HT2AR),and 5-HT transporter (serotonin transporter [SERT]) are associated with different disease states of depression,myocardial infarction (MI) and MI co-exist with depression in Sprague-Dawley rats.Methods:After established the animal model of four groups include control,depression,MI and MI with depression,we measured 5-HT,5-HT2AR and SERT from serum and platelet lysate.Results:The serum concentration of 5-HT in depression rats decreased significantly compared with the control group (303.25 ± 9.99 vs.352.98 ± 13.73;P =0.000),while that in MI group increased (381.78 ± 14.17 vs.352.98 ± 13.73;P =0.000).However,the depression + MI group had no change compared with control group (360.62 ± 11.40 vs.352.98 ± 13.73;P =0.036).The changes of the platelet concentration of 5-HT in the depression,MI,and depression + MI group were different from that of serum.The levels of 5-HT in above three groups were lower than that in the control group (380.40 ± 17.90,387.75 ± 22.28,246.40 ± 18.99 vs.500.29 ± 20.91;P =0.000).The platelet lysate concentration of 5-HT2AR increased in depression group,MI group,and depression + MI group compared with the control group (370.75 ± 14.75,393.47 ± 15.73,446.66 ± 18.86 vs.273.66 ± 16.90;P =0.000).The serum and platelet concentration of SERT in the depression group,MI group and depression + MI group were all increased compared with the control group (527.51 ± 28.32,602.02 ± 23.32,734.76 ± 29.59 vs.490.56 ± 16.90;P =0.047,P =0.000,P =0.000 in each and 906.38 ± 51.84,897.33 ± 60.34,1030.17 ± 58.73 vs.708.62 ± 51.15;P =0.000 in each).Conclusions:The concentration of 5-HT2AR in platelet lysate and SERT in serum and platelet may be involved in the pathway of MI with depression.Further studies should examine whether elevated 5-HT2AR and SERT may contribute to the biomarker in MI patients with depression.

Depression following myocardial infarction--an overseen complication with prognostic importance.

2013-08-01

Myocardial infarction (MI) is a severe life event that is accompanied by an increased risk of depression. Mounting evidence suggests that post-MI depression is associated with adverse outcomes, but the underlying mechanisms of this association remain unclear, and no previous studies have examined whether the mental burden of MI is so heavy that it increases the risk of suicide. Although post-MI depression is common and burdensome, the condition remains under-recognised and under-treated. The development of new strategies to improve the quality of care for people with post-MI depression requires thorough understanding of the mechanisms that influence the prognosis as well as knowledge of the present care provided. The purpose of this PhD thesis is accordingly subdivided into four specific aims: 1. To estimate the prevalence of depression in people with MI after three months, and to estimate the provided hospital-based psychosocial rehabilitation (Paper I); 2. To examine GPs' practice of screening for depression in people with MI, and to analyse whether the screening rate varied among subgroups of people with a particularly high risk of post-MI depression (Paper II); 3. To examine the association between post-MI depression and new cardiovascular events or death, taking potential mediators into account (Paper III); 4. To examine the association between MI and suicide (Paper IV). Two different study designs were employed: a population-based cohort study using data obtained from registers and questionnaires sent to MI patients and their GPs (Paper I-III); a nationwide population-based matched case-control study using data obtained from registers (Paper IV). Three months after having suffered MI, about one fifth of the patients in our study had depression according to the Hospital Anxiety and Depression Scale (HADS). Upwards of half of the patients had participated in some rehabilitation, thirty per cent had participated in psychosocial support and three per cent

Multiple Thromboembolic Cerebral Infarctions from the Aorta in a Patient with Churg-Strauss Syndrome.

2017-02-01

Ischemic stroke is a rare complication of Churg-Strauss syndrome (CSS) and its pathogenesis has not been well clarified yet. We report a case of cerebral infarction in a patient with CSS due to embolism from a thrombus on the wall of the aorta. A 39-year-old man had multiple cerebral infarctions with symptoms of mild left hemiparesis and reduced vision. He was clinically diagnosed to have CSS based on remarkable eosinophilia, history of asthma, sinusitis, pulmonary infiltrates, and histologically proven extravascular eosinophilic infiltrates in the specimen of gastric mucosa. Cerebral angiography did not show any stenotic lesions in cerebral arteries. A thrombus was detected on the wall of the aorta by transesophageal echocardiography, which was considered as the source of embolism. The thrombus resolved on follow-up examination 3 months after the onset of the stroke. This is the first case report on cerebral infarction caused by aortogenic thromboembolism in a CSS patient. Other than cerebral vasculitis, embolism from cardiovascular system, including the wall of the aorta, is a possible cause of cerebral infarctions in a CSS patient.

Full Text Available Objectives: Multiple Sclerosis is one of the most important and prevalent central nervous system diseases, causing disorders such as depression among affected patients. Positive psychotherapy is also a new approach that can be effective in reducing the depression of these people. This study aims to investigate the efficiency of group positive psychotherapy for decreasing the depression among females affected by Multiple Sclerosis. Methods: A samples of 30 females affected by Multiple Sclerosis with mild to moderate depression were participated, and were divided into two groups, intervention and control. Both groups completed Beck Depression Inventory II (BDI-II at the beginning, he intervention group received six sessions of positive psychotherapy. After the intervention both group completed the questionnaire again. Data was analyzed by descriptive and inferential statistical methods. Results: The result demonstrated that, the decline of depression was more in the intervention group than the control group. Moreover in the intervention group than control group, there was obtained significant reduction in both sub-scales of Beck Depression Inventory II. Discussion: Results of this study indicated that group positive psychotherapy is effective in reducing the depression of females affected by Multiple Sclerosis. This treatment can be widely used in the caring centers for treatment of people affected by Multiple Sclerosis and this can be justified because of its low cost and good efficiency.

With the advent of faster scan time and new computer program, a scanning technique called 'dynamic computed tomography' has become possible. Dynamic computed tomography consisted of performing multiple rapid sequence scans after injection of contrast material. The authors have evaluated the clinical usefulness of computed tomography and dynamic computed tomography of 93 patients with brain infarction and/or ischemia during the period of 17 months from April 1983 to August 1984 in Department of Radiology, Chonbuk National University Hospital. The results were as follows; 1. The age distribution ranged from 18 years to 78 years. Among them the most common age group was between 50 years and 59 years (40.9%). 2. The sites of brain infarction were cerebral lobes (63 cases,68), basal ganglia (15 cases, 16.1%) and multiple sites (6 cases, 6.4%). The common affected site was middle cerebral artery territories. 3. The contrast enhancement of acute infarction was noted in 14 cases (17.5%) which occurred commonly between 3 days and 2 weeks from ictus. 4. The patterns of time-density curve in brain infarction and/or ischemia were as follow: a. Depression of slow wash-in phase was 20 cases (59%). b. Lower peak concentration was 17 cases (50%). c. Lower and delayed peak concentration was 7 cases (21%). d. No definite peak concentration was 6 cases (18%). First three patterns of time-density curve were thought as relatively characteristic curve of brain infarction and/or ischemia. 5. Two cases that showed negative findings on precontrast CT scan appeared to be positive findings as hypodensity on postcontrast CT scan and were confirmed as brain infarction by dynamic CT. 6. The diagnostic entity of dynamic CT scan were as follows; a. large artery thrombotic infarction were 23 cases (58%). b. lacnar infarction were 6 cases (15%). c. ischemia were 5 cases (13%). d. normal were 5 cases (13%). In six cases of lacunar infarction which was double hypodensity on pre-and postcontrast CT

It has been noticed that the patients with multiple system atrophy (MSA) can accompany with depression and anxiety. This study aimed to establish the incidence and determinants of depression and anxiety symptoms in Chinese MSA patients. A total of 237 MSA patients were enrolled in the study. Neuropsychological assessment was performed using Hamilton Depression Rating Scale-24 items and Hamilton Anxiety Rating Scale. We found that 62.0% and 71.7% patients had at least mild depression and anxiety symptoms, respectively. The severity of depression of MSA patients was associated with lower educational years (P=.024), longer disease duration (Panxiety was associated with increased disease duration (Panxiety were female gender, longer disease duration, and disease severity. Depression and anxiety symptoms are common in patients with MSA. Neurologists should pay attention to depression and anxiety in patients with MSA, especially in female patients and those with longer disease duration and severe disease condition. © 2017 John Wiley & Sons A/S.

Bothrops caribbaeus, a species of the Bothrops complex, is found only in the island of Saint Lucia, West Indies. Snakebite from this pitviper is very rare. We report the case of a healthy 32-year-old Saint Lucian man who developed multiple cerebral infarctions following envenoming by this snake. This patient developed signs and symptoms very similar to those observed in patients envenomed by Bothrops lanceolatus, a snake found only in Martinique, the neighbor island of Saint Lucia. This clinical presentation differs dramatically from coagulopathies and systemic bleeding observed with the Central and South American bothropic envenomings. The exact mechanism of this thrombogenic phenomenon, leading to a unique envenoming syndrome, remains unknown.

Post-menopausal women are at significant risk for coronary artery disease, have increased rates of depression compared to their male counterparts, and often present atypically with coronary insufficiency. The symptoms of depression and coronary ischemia overlap greatly. Complaints like fatigue, body aches, and sleep disturbance reported by a depressed elderly woman may be cardiac related and need to be investigated seriously without physician bias. To ensure that clinicians are cautious when evaluating older women with a history of depression who are presenting with atypical complaints. A 61-year-old woman with history of depression presented to the Emergency Department with multiple complaints atypical for acute coronary syndrome. She had an immediate electrocardiogram and troponin-T Biosite point-of-care test (Biosite Incorporated, San Diego, CA) performed, which were positive for cardiac ischemia and myocardial infarction. The patient underwent immediate cardiac catheterization, which revealed occlusion of the mid left circumflex. After aspiration of thrombus and balloon dilatation of the site, a bare metal stent was deployed, restoring excellent flow. The patient did well medically but her depression worsened after the procedure and continues despite psychiatric intervention. For years there have been gender differences in medical treatment of coronary artery disease, and often women's complaints are not investigated aggressively. Post-menopausal women are at great risk for cardiac ischemia and depression, and their symptoms, which are often atypical, may not be diagnosed as anginal equivalents. In addition, depression is an independent risk factor for cardiovascular disease and, if it occurs after myocardial infarction, may lead to poor quality of life and increased morbidity and mortality. Patients who have had a coronary event must be thoroughly evaluated for signs of depression and receive the necessary treatment. Published by Elsevier Inc.

The cause and associated pathophysiology of precordial ST-segment depression during acute inferior myocardial infarction (IMI) are controversial. To investigate this problem, electrocardiographic findings in 48 consecutive patients with acute IMI were prospectively compared with results of coronary angiography, submaximal exercise thallium-201 ( 201 Tl) scintigraphy and multigated blood pool imaging, all obtained 2 weeks after IMI, and with clinical follow-up at 3 months. Patients were classified according to the admission ECG obtained 3.3 +/- 3.1 hours after the onset of chest pain. Twenty-one patients (group A) had no or 201 Tl perfusion abnormalities (p 201 Tl defects or wall motion abnormalities in anterior or septal segments

MRI findings and risk factors for vascular dementia were evaluated with multi-variate analysis in 96 multi-infarct patients without dementia and 40 multi-infarct patients with dementia (MID). Only subjects with small infarcts in the territory of the perforator artery or deep white matter were studied. The diagnosis of MID was diagnosed according to DMS-III criteria and Hachinski's ischemia score. Location and area of patchy high-intensity areas including small infarcts, the degree of periventricular high intensity (PVH), and the degree of brain atrophy were examined with MR images. Independent variables were: history of hypertension, diabetes mellitus, other complications; systolic and diastolic blood pressure, atherosclerotic index, hematocrit, history of smoking, level of education, and activities of daily life (ADL). Hayashi's quantification method II was used to analyze the data. The most significant correlation was found between history of hypertension and dementia (partial correlation coefficient: 0.39). Significant correlations were also found between ADL and dementia (0.32), between thalamic infarction and dementia (0.31), and between PVH and dementia (0.27). Age, brain atrophy index, and history of diabetes mellitus contributed little to dementia. The contribution to dementia did not differ significantly between right and left patchy high-intensity areas on MR images. Location of infarcts, except for bilateral thalamic infarcts and large PVH, contributed little to dementia. Thus it would be difficult to base a prediction of the prevalence of vascular dementia on MRI findings. However, both hypertention and ADL contribute to vascular dementia and both are treatable, which may be significant for the prevention of dementia. (author)

Full Text Available Identification of the infarct-related artery (IRA in patients with STEMI using coronary angiography (CA is often based on the ECG and can be challenging in patients with severe multi-vessel disease. The current study aimed to determine how often percutaneous intervention (PCI is performed in a coronary artery different from the artery supplying the territory of acute infarction on cardiac magnetic resonance imaging (CMR.We evaluated 113 patients from the Reduction of infarct Expansion and Ventricular remodeling with Erythropoetin After Large myocardial infarction (REVEAL trial, who underwent CMR within 4±2 days of revascularization. Blinded reviewers interpreted CA to determine the IRA and CMR to determine the location of infarction on a 17-segment model. In patients with multiple infarcts on CMR, acuity was determined with T2-weighted imaging and/or evidence of microvascular obstruction.A total of 5 (4% patients were found to have a mismatch between the IRA identified on CMR and CA. In 4/5 cases, there were multiple infarcts noted on CMR. Thirteen patients (11.5% had multiple infarcts in separate territories on CMR with 4 patients (3.5% having multiple acute infarcts and 9 patients (8% having both acute and chronic infarcts.In this select population of patients, the identification of the IRA by CA was incorrect in 4% of patients presenting with STEMI. Four patients with a mismatch had an acute infarction in more than one coronary artery territory on CMR. The role of CMR in patients presenting with STEMI with multi-vessel disease on CA deserves further investigation.

We report two children with severe neurological complications after having been stung by a scorpion. Clinical and MRI findings suggested brain infarcts. The lesions seen were in pons in one child and the right hemisphere in the other. The latter also showed possible hyperemia in the infarcted area. No vascular occlusions were observed and we therefore think the brain infarcts were a consequence of the scorpion sting. The cause of the infarct may be hypotension, shock or depressed left ventricular function, all of which are frequent in severe poisoning by scorpion sting. (orig.)

Forty consecutive patients with creatine kinase-MB confirmed myocardial infarction due to circumflex artery occlusion (Group 1) were prospectively evaluated and compared with 107 patients with infarction due to right coronary artery occlusion (Group 2) and 94 with left anterior descending artery occlusion (Group 3). All 241 patients underwent exercise thallium-201 scintigraphy, radionuclide ventriculography, 24 h Holter electrocardiographic (ECG) monitoring and coronary arteriography before hospital discharge and were followed up for 39 +/- 18 months. There were no significant differences among the three infarct groups in age, gender, number of risk factors, prevalence and type of prior infarction, Norris index, Killip class and frequency of in-hospital complications. Acute ST segment elevation was present in only 48% of patients in Group 1 versus 71 and 72% in Groups 2 and 3, respectively (p = 0.012), and 38% of patients with a circumflex artery-related infarct had no significant ST changes (that is, elevation or depression) on admission (versus 21 and 20% for patients in Groups 2 and 3, respectively) (p = 0.001). Abnormal R waves in lead V1 were more common in Group 1 than in Group 2 (p less than 0.003) as was ST elevation in leads I, aVL and V4 to V6 (p less than or equal to 0.048). These differences in ECG findings between Group 1 and 2 patients correlated with a significantly higher prevalence of posterior and lateral wall asynergy in the group with a circumflex artery-related infarct. Infarct size based on peak creatine kinase levels and multiple radionuclide variables was intermediate in Group 1 compared with that in Group 2 (smallest) and Group 3 (largest). During long-term follow-up, the probability of recurrent cardiac events was similar in the three infarct groups

To evaluate the regional contractile state of the non-infarcted zone and to determine the contribution of this area to left ventricular (LV) performance, 112 patients (42 anterior and 70 inferior infarction) with their first acute myocardial infarction were investigated by radionuclide ventriculography at admission and 10 days after admission. Wall motion at the non-infarcted area was defined as hyperkinetic, normal, or hypokinetic, if radial chord shortening had above normal, normal, or below normal values, respectively, by quantitative wall motion analysis. Hyperkinetic, normal, and hypokinetic wall motion of the non-infarcted area were observed in three (7 %), 12 (29 %), and 27 (64 %) patients in anterior infarction and 14 (20 %), 28 (40 %), and 28 (40 %) in inferior infarction, respectively. In the patients with hypokinetic wall motion at the non-infarcted area, the infarct involved more than 30 % of the left ventricle manifesting akinetic contractile segment (ACS), radial chord shortening in the infarcted area was severely depressed, and the incidence of multi-vessel involvement was higher compared with those with hyperkinetic or normal wall motion. In serial measurements, radial chord shortening in the infarcted and non-infarcted area, percent ACS, left ventricular ejection fraction, and left ventricular end-diastolic volume index did not change significantly from acute to follow-up study in any group. In conclusion, our data indicated that the non-infarcted area following acute infarction had various contractile states and these conditions were determined primarily by the severity and extent of infarct and underlying coronary artery disease. Furthermore, the contractile state of the non-infarcted area has a supplemental role in determination of LV function following acute infarction. (author)

Attributional Style and Depression in Multiple Sclerosis

Arnett, Peter A.

2013-01-01

Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS in 52 patients with MS to test the LH theory in this population and to determine possible differences between illness-related and non-illness-related attributions. Patients were administered measures of attributional style, daily stressors, disability, and depressive symptoms. Participants were more likely to list non-MS-related than MS-related causes of negative events on the Attributional Style Questionnaire (ASQ), and more-disabled participants listed significantly more MS-related causes than did less-disabled individuals. Non-MS-related attributional style correlated with stress and depressive symptoms, but MS-related attributional style did not correlate with disability or depressive symptoms. Stress mediated the effect of non-MS-related attributional style on depressive symptoms. These results suggest that, although attributional style appears to be an important construct in MS, it does not seem to be related directly to depressive symptoms; rather, it is related to more perceived stress, which in turn is related to increased depressive symptoms.

Despite the fact that pain is related to depression, few studies have been conducted to investigate the variables that mediate between the two conditions. In this study, the authors explored the following mediators: cognitive function, self-sacrificing interpersonal problems, and perception of stress, and the effects they had on pain symptoms among patients with depressive disorders. An analysis was performed on the data of 346 participants with unipolar depressive disorders. The 17-item Hamilton Depression Rating Scale, Mini-Mental State Examination, the pain subscale of the health-related quality of life (SF-36), the self-sacrificing subscale of the Inventory of Interpersonal Problems, and the Perceived Stress Scale were used. Parallel multiple mediator and serial multiple mediator models were used. An alternative model regarding the effect of self-sacrificing on pain was also proposed. Perceived stress, self-sacrificing interpersonal style, and cognitive function were found to significantly mediate the relationship between depression and pain, while controlling for demographic variables. The total effect of depression on pain was significant. This model, with an additional three mediators, accounted for 15% of the explained variance in pain compared to 9% without mediators. For the alternative model, after controlling for the mediators, a nonsignificant total direct effect level of self-sacrificing was found, suggesting that the effect of self-sacrificing on pain was based only on an indirect effect and that perceived stress was found to be the strongest mediator. Serial mediation may help us to see how depression and pain are linked and what the fundamental mediators are in the chain. No significant, indirect effect of self-sacrificing on pain was observed, if perceived stress was not part of the depression and/or cognitive function mediational chain. The results shown here have implications for future research, both in terms of testing the model and in

The aim of this study was to validate a Persian version of the Cardiac Depression Scale (CDS) in Iranian patients with acute myocardial infarction (AMI). The CDS was forward translated from English into Persian and back-translated to English. Validity was assessed using face, content, and construct validity. Also Cronbach's alpha (α), theta (), and McDonald's omega coefficient were used to evaluate the reliability. Construct validity of the scale showed two factors with eigenvalues greater than one. The Cronbach's α, , McDonald's omega, and construct reliability were greater than .70. The Persian version of the CDS has a two-factor structure (i.e., death anxiety and life satisfaction) and has acceptable reliability and validity. Therefore, the validated instrument can be used in future studies to assess depression in patients with AMI in Iranians.

This study describes a simplified approach for the interpretation of electrocardiographic and thallium-201 imaging data derived from the same patient during exercise. The 383 patients in this study had also undergone selective coronary arteriography within 3 months of the exercise test. This matrix approach allows for multiple test outcomes (both tests positive, both negative, 1 test positive and 1 negative) and multiple disease states (no coronary artery disease vs 1-vessel vs multivessel coronary artery disease). Because this approach analyzes the results of 2 test outcomes simultaneously rather than serially, it also negates the lack of test independence, if such an effect is present. It is also demonstrated that ST-segment depression on the electrocardiogram and defects on initial thallium-201 images provide conditionally independent information regarding the presence of coronary artery disease in patients without prior myocardial infarction. In contrast, ST-segment depression on the electrocardiogram and redistribution on the delayed thallium-201 images may not provide totally independent information regarding the presence of exercise-induced ischemia in patients with or without myocardial infarction

Findings regarding the association between depression and risk of coronary heart disease are inconsistent. We aimed to assess the association between depression and risk of myocardial infarction (MI) and coronary death through a meta-analysis.We performed an electronic literature search of MEDLINE, EMBASE, PsycINFO, ISI Web of Science, and Scopus databases through August 1, 2015, and manual search of the references of the eligible papers and related review articles. Two investigators independently conducted study selection and data abstraction. Disagreement was resolved by consensus. Confounder-adjusted hazard ratios (HRs) were pooled using a random-effects model. Heterogeneity was evaluated using the Cochran Q statistic and Higgins index. Publication bias was assessed by funnel plot and Egger test. Study quality was appraised with the Newcastle-Ottawa Scale.Among 19 eligible cohort studies including 323,709 participants, 8447 cases of MI and coronary death were reported during follow-up ranging from 4 to 37 years. The pooled adjusted HRs for patients with depression (vs those without) were 1.22 (95% CI, 1.13-1.32) for combined MI and coronary death, 1.31 (95% CI, 1.09-1.57) for MI alone (9 studies), and 1.36 (95% CI, 1.14-1.63) for coronary death alone (8 studies). The increased risk of MI and coronary death associated with depression was consistent using modified inclusion criteria, across most subgroups, and after adjusting for possible publication bias.Depression is associated with a significantly increased risk of MI and coronary death. Effective prevention and treatment of depression may decrease such risk.

Anxiety and depressive symptoms are associated with adverse cardiovascular events after an acute myocardial infarction (MI). However, most studies focusing on anxiety or depression have used rating scales or self-report methods rather than clinical diagnosis. This study aimed to investigate the association between psychiatrist-diagnosed psychiatric disorders and cardiovascular prognosis.We sampled data from the National Health Insurance Research Database; 1396 patients with MI were recruited as the study cohort and 13,960 patients without MI were recruited as the comparison cohort. Cox proportional hazard regression models were used to examine the effect of MI on the risk of anxiety and depressive disorders.During the first 2 years of follow-up, patients with MI exhibited a significantly higher risk of anxiety disorders (adjusted hazard ratio [HR] = 5.06, 95% confidence interval [CI]: 4.61-5.54) and depressive disorders (adjusted HR = 7.23, 95% CI: 4.88-10.88) than those without MI did. Greater risk for anxiety and depressive disorders was observed among women and patients aged 45 to 64 years following an acute MI. Patients with post-MI anxiety had a 9.37-fold (95% CI: 4.45-19.70) higher risk of recurrent MI than those without MI did after adjustment for age, sex, socioeconomic status, and comorbidities.This nationwide population-based cohort study provides evidence that MI increases the risk of anxiety and depressive disorders during the first 2 years post-MI, and post-MI anxiety disorders are associated with a higher risk of recurrent MI.

Background:While depression and certain cardiac biomarkers are associated with acute myocardial infarction (AMI),the relationship between them remains largely unexplored.We examined the association between depressive symptoms and biomarkers in patients with AMI.Methods:We performed a cross-sectional study using data from 103 patients with AMI between March 2013 and September 2014.The levels of depression,N-terminal proB-type natriuretic peptide (NT-proBNP),and troponin I (TnI) were measured at baseline.The patients were divided into two groups:those with depressive symptoms and those without depressive symptoms according to Zung Self-rating Depression Scale (SDS) score.Baseline comparisons between two groups were made using Student's t-test for continuous variables,Chi-square or Fisher's exact test for categorical variables,and Wilcoxon test for variables in skewed distribution.Binomial logistic regression and multivariate linear regression were performed to assess the association between depressive symptoms and biomarkers while adjusting for demographic and clinical variables.Results:Patients with depressive symptoms had significantly higher NT-proBNP levels as compared to patients without depressive symptoms (1135.0 [131.5,2474.0] vs.384.0 [133.0,990.0],Z =-2.470,P =0.013).Depressive symptoms were associated with higher NT-proBNP levels (odds ratio [OR] =2.348,95％ CI:1.344 to 4.103,P =0.003) and higher body mass index (OR =1.169,95％ confidence interval [CI]:1.016 to 1.345,P =0.029).The total SDS score was associated with the NT-proBNP level (β =0.327,95％ CI:1.674 to 6.119,P =0.001) after multivariable adjustment.In particular,NT-proBNP was associated with three of the depressive dimensions,including core depression (β =0.299,95％ CI:0.551 to 2.428,P =0.002),cognitive depression (β =0.320,95％ CI:0.476 to 1.811,P=0.001),and somatic depression (β =0.333,95％ CI:0.240 to 0.847,P =0.001).Neither the overall depressive symptomatology nor the individual

Depressive symptoms occur frequently in people with Multiple Sclerosis (MS) and rates of suicide ideation are higher than the general population. There is evidence for a direct association between disability and depression, disability and suicide ideation, and depression and suicide ideation in MS. However, the relationship between all three, i.e. the mediating role of depression between disability and suicidal ideation, has not been investigated. Exploring this relationship could highlight risk factors, alerting clinicians to the need for timely intervention. Seventy five people with progressive MS attending two out-patient clinics took part in this cross-sectional study. Participants completed the Beck Suicide Scale, Beck Depression Inventory, Multiple Sclerosis Impact Scale and Guy's Neurological Disability Scale. Depressive symptoms mediated the relationship between perceived and actual disability and suicide ideation. Different types of disability were associated with suicidality, including: 'tremors' and 'taking longer to do things'. A small sub-group of participants were identified who reported suicide ideation in the presence of only mild levels of depression. There may be a sample bias in this study as all participants were attending out-patient clinics and receiving support which may not be available to everyone with MS. It is important for clinicians to screen regularly for both depression and suicide ideation, to be alert to specific types of disability for which a higher level of suicide ideation might be present and to consider the possibility of suicidal thoughts being present in people who show minimal or no depressive symptoms.

Full Text Available OBJECTIVE: This study was carried out to determine the level of hopelessness, depression, and life satisfaction among patients with multiple sclerosis. METHODS: 65 patients with multiple sclerosis, treated at the neurology clinic of a university hospital, were included in this study. In this descriptive study, a data collection form developed by the researchers, the Beck Depression Scale, and the Beck Hopelessness and Life Satisfaction Scale were used. RESULTS: Almost half (43.1% of the patients exhibited severe depressive symptoms. Patients’ hopelessness and life satisfaction levels were moderate. The scores on depression and life satisfaction scales were correlated negatively. While patients’ traits including female gender, low economic level, difficulties in walking, and fatigue were associated with reduced life satisfaction; variables such as having a child, low economic and education levels, experiencing incontinence, and fatigue were related to a higher level of depressive symptoms. CONCLUSION: The majority of patients were depressed; life satisfaction and hopelessness levels were moderate. Linear regression analysis revealed that education and emotional problems determined 42% of the depression score; and economic level and emotional problems identified 32% of the life satisfaction score

Although multiple studies of adolescents have examined the association of depression with individual health risk behaviors such as obesity or smoking, this is one of the few studies that examined the association between depression and multiple risk behaviors. A brief mail questionnaire, which screened for age, gender, weight, height, sedentary behaviors, physical activity, perception of general health, functional impairment and depressive symptoms, was completed by a sample of 2291 youth (60.7% response rate) aged 13-17 enrolled in a health care plan. A subset of youth who screened positive on the two-item depression screen and a random sample of those screening negative were approached to participate in a telephone interview with more in-depth information obtained on smoking and at-risk behaviors associated with drug and alcohol use. Youth screening positive for high levels of depressive symptoms compared to those with few or no depressive symptoms were significantly more likely to meet criteria for obesity, had a poorer perception of health, spent more time on the computer, got along less well with parents and friends, had more problems completing school work and were more likely to have experimented with smoking and a wide array of behaviors associated with drug and alcohol use. Because many adverse health behaviors that develop in adolescence continue into adulthood, the association of depressive symptoms with multiple risk behaviors and poor functioning suggest that early interventions are needed at an individual, school, community and primary care level.

Depression and anxiety after myocardial infarction (MI) are common and associated with increased morbidity and mortality. The epidemiology and pathophysiology of MI due to spontaneous coronary artery dissection (SCAD) differs substantially from atherosclerotic MI, and rates of mental health comorbidities after SCAD are unknown. We aimed to determine the prevalence and predictors of depression/anxiety in SCAD survivors. In this cross-sectional study, 158 SCAD survivors (97% women; mean age, 45.5 ± 9.3 years) were screened for depression/anxiety via surveys, including the Patient Health Questionnaire Depression Scale (PHQ-9) and Generalized Anxiety Disorder 7-Item Scale (GAD-7), a mean 3.7 ± 4.7 years after SCAD. Comorbidities and environmental, socioeconomic, and clinical cardiovascular characteristics were obtained from the surveys. Since their initial SCAD MI, 51 (33%) patients had received treatment with medications or counseling for depression and 57 (37%) for anxiety. When surveyed, 46 (31.7%) were taking antidepressant or anxiolytic medications. Overall, mean PHQ-9 (4.1) and GAD-7 (4.7) scores suggested borderline mild depression/anxiety (normal range: 0-4). Younger age was associated with higher PHQ-9 (P = .04) and GAD-7 (P = .02) scores. The 19 (12%) patients with peripartum SCAD had higher mean PHQ-9 (6.7 vs 3.7; P Patients treated with percutaneous coronary intervention had lower PHQ-9 (1.5; P = .02) and GAD-7 (2.4; P = .004) scores. Symptoms of depression/anxiety are common in patients with MI due to SCAD, particularly younger women and those with peripartum SCAD. The PHQ-9 and GAD-7 assessments may detect depression/anxiety in SCAD survivors who do not self-report these disorders, suggesting a role for routine screening in these patients.

Diagnosis of pediatric neuropsychiatric disorders such as unipolar depression is largely based on clinical judgment - without objective biomarkers to guide diagnostic process and subsequent therapeutic interventions. Neuroimaging studies have previously reported average group-level neuroanatomical differences between patients with pediatric unipolar depression and healthy controls. In the present study, we investigated the utility of multiple neuromorphometric indices in distinguishing pediatric unipolar depression patients from healthy controls at an individual subject level. We acquired structural T1-weighted scans from 25 pediatric unipolar depression patients and 26 demographically matched healthy controls. Multiple neuromorphometric indices such as cortical thickness, volume, and cortical folding patterns were obtained. A support vector machine pattern classification model was 'trained' to distinguish individual subjects with pediatric unipolar depression from healthy controls based on multiple neuromorphometric indices and model predictive validity (sensitivity and specificity) calculated. The model correctly identified 40 out of 51 subjects translating to 78.4% accuracy, 76.0% sensitivity and 80.8% specificity, chi-square p-value = 0.000049. Volumetric and cortical folding abnormalities in the right thalamus and right temporal pole respectively were most central in distinguishing individual patients with pediatric unipolar depression from healthy controls. These findings provide evidence that a support vector machine pattern classification model using multiple neuromorphometric indices may qualify as diagnostic marker for pediatric unipolar depression. In addition, our results identified the most relevant neuromorphometric features in distinguishing PUD patients from healthy controls. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available Psychological reactions, risk health behavior and cardiac parameters can influence rehospitalization after acute myocardial infarction.The aim of the paper was to determine the presence of psychological reactions and risk health behavior in patients with acute myocardial infarction on admission as well as the differences after six months.The research included thirty-trhee patients of both sexes, who were consecutively hospitalized due to acute myocardial infarction. A prospective clinical investigation involved the following: semi-structured interview, Mini International Neuropsychiatric Interview (M.I.N.I for pcychiatric disorders, Beck Anxiety Inventory (BAI for measuring the severity of anxiety, Beck Depression Inventory (BDI for measuring the severity of depression, KON-6 sigma test for aggression, Holms-Rahe Scale (H-R for exposure to stressful events, and Health Behavior Questionnaire: alcohol consumption, cigarette smoking, lack of physical activity. Measurement of the same parameters was done on admission and after six months. The differences were assessed using the t-test and chi-square test for p<0.05.On admission, anxiety (BAI=8.15±4.37 and depression (BDI=8.67±3.94 were mild without significant difference after six months in the group of examinees. Aggression was elevated and significantly lowered after six monts (KON-6 sigma =53,26±9, 58:41,42±7.67, t=2,13 for p<0.05. Exposure to stressful events in this period decreased (H-R=113.19±67.37:91,65±63,81, t=3,14 for p<0.05; distribution of physical activity was significantly higher compared to admission values (54.83%: 84.84%. χ2=5.07 for p<0.01.In the group of examinees with acute myocardial infarction in the period of six months, anxiety and depression remained mildly icreased, while the levels of aggression and exposure to stressful events were lowered. Risk health behavior was maintained, except for the improvement in physical activity. In the integrative therapy and

Objective: Limited research has examined the psychometric properties of death depression scales in Persian populations with cardiac disease despite the need for valid assessment tools for evaluating depressive symptoms in patients with life-limiting chronic conditions. The present study aimed at evaluating the reliability and validity of the Persian Version of Death Depression Scale - Revised (DDS-R) in Iranian patients who had recent acute myocardial infarction (AMI). Method: This psychometric study was conducted with a convenience sample of 407 patients with AMI diagnosis who completed the Persian version of the DDS-R. The face, content, and construct validity of the scale were ascertained. Internal consistency, test-retest, and construct reliability (CR) were used to assess reliability of the Persian Version of DDS-R. Results: Based on maximum likelihood exploratory factor analysis and consideration of conceptual meaning, a 4-factor solution was identified, explaining 75.89% of the total variance. Goodness-of-fit indices (GFI), Comparative Fit Index (CFI), Normed Fit Index (NFI), Incremental Fit Index (IFI), and Root Mean Square Error of Approximation (RMSEA) in the final DDS-R structure demonstrated the adequacy of the 4-domain structure. The internal consistency, construct reliability, and Intra-class Correlation Coefficients (ICC) were greater than .70. Conclusion: The DDS-R was found to be a valid and reliable assessment tool for evaluating death depression symptoms in Iranian patients with AMI.

Self-reported everyday memory and depression in patients with multiple sclerosis.

Depression and memory difficulties are among the most common complaints voiced by patients with multiple sclerosis (MS). Nevertheless, little is known about how depression might affect patients' perceptions of their memory difficulties. The present investigation was designed to explore this issue. Results supported a model that integrates aspects of Beck's theory of depression and the concept of depressive realism. Consistent with the depressive realism literature, nondepressed MS patients significantly overestimated their everyday memory compared with their actual performance on verbal memory and attention/concentration indices, whereas moderately depressed patients' everyday memory ratings mirrored their actual neuropsychological performance. Supporting Beck's negative cognitive schema notion, mildly depressed patients significantly overestimated their memory difficulties. Implications for the treatment of memory problems among MS patients are discussed.

We present a case of pulmonary infraction caused by thrombosis secondary to tuberculoma. The patient came to the Emergency Room of our hospital with dyspnea and chest pain. Chest X-ray revealed right basal pleuroparenchymal involvement and three nodules located in both lungs. Computed tomography disclosed several triangular images suggestive of infarcts in right lung base. It also showed the high attenuation of the pulmonary nodules, which initially suggested a diagnosis of tuberculous granulomas. Lung biopsy was necessary for the definitive diagnosis of the two lesions. The histopathological study reveals the cause of the infarcts to be arterial thrombosis produced by the entrapment of blood vessels in the fibrotic reaction of the granuloma, a finding that had not been reported in the literature to date.

Up to one fifth of patients with cardiovascular disease, including those who have experienced a myocardial infarction, may have concomitant major depression. Studies have suggested that the relative risk of major depression with cardiovascular disease ranges from 1.5 to 4.5. Further information is required to establish a dose-response relationship between depression and coronary artery disease (CAD); however, such a relationship has been shown between anxiety and CAD. Development of a conceptual model of the pathophysiologic actions of stress in CAD will assist in the understanding of this relationship. In patients with angiographic evidence of CAD, the presence of major depressive disorder was the best single predictor of cardiac events during the 12 months following diagnosis. Significantly, 6-month cumulative mortality following diagnosis of myocardial infarction has been shown to be higher in depressed patients than in nondepressed patients. A decrease in heart rate variability may mediate the deleterious effect of depression on post-myocardial infarction prognosis. Other factors such as mental stress and altered platelet function may also predispose depressed patients to a heightened risk of cardiac events. With an increased understanding of the relationship between depression and heightened risk of cardiovascular mortality, it is necessary to assess current overall treatment for cardiac patients.

Messer, Michael M; Haller, Irina V

2017-01-01

Objective: Depression is a common condition among patients with multiple sclerosis and often becomes resistant to oral antidepressants. We report a patient with multiple sclerosis who developed severe treatment-resistant depression and who was successfully treated with intravenous ketamine over the period of two years. Methods: Ketamine treatment protocol included an initial series of six treatments administered every other day, followed by a maintenance schedule. Ketamine was administered intravenously at 0.5mg/kg of ideal body weight over 40 minutes. Depression symptoms were measured using Beck Depression Index. Results: The patient's Beck Depression Index score prior to initiating ketamine treatment was 38, corresponding to severe depression. Response to treatment, defined as 50-percent reduction in Beck Depression Index score, was observed after five treatments. For this patient, the maintenance schedule ranged from a weekly treatment to one treatment every three weeks. During the two-year observation period, this patient was able to maintain a stable non-depressed mood and had no worsening of her MS symptoms. Conclusion: Ketamine may be an alternative treatment for resistant depression and may have a special use in patients with multiple sclerosis.

Attributional Style and Depression in Multiple Sclerosis: The Learned Helplessness Model

OpenAIRE

Vargas, Gray A.; Arnett, Peter A.

2013-01-01

Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS...

Mukai, Kanji; Hondo, Hideki; Ueda, Shin; Matsumoto, Keizo

1989-01-01

During the previous 2 years, 88 patients have been diagnosed as having lacunar infarcts in the basal ganglioa ( a total of 157 lesions) on magnetic resonance imaging (MRI):42 patients had a single lesion and 46 patients had multiple lesions (2 lesions in 25 patients, 3 lesions in 14, and 4 or more lesions in 7). Seventy-seven lesions (49%) were smaller than 5 mm in diameter, and the others ranged from 5 mm to 15 mm. According to the regional relations to the internal capsule, the lesions were classified as lateral (57 lesions), anterior (36), superior (34), posterior (26), and inferior (4). Lesions of posterior, anterior, superior, and inferior types were associated with severer hemisparetic state, an abnormally slow gait, a sensory disturbance of numbness, and a depressive state, respectively. Forty five lesions (28%) were asymptomatic. Cat scanning failed to deliniate 47 lesions (30%) that were detected on MRI. Twenty three lesions were both asymptomatic and undistinguished on CT, which consisted of the superior type (10), anteior type (7), lateral type (5), and posterior type (one). Twenty four lesions were symptomatic, but were undistinguished on CT, suggesting that MRI is superior to CT in detecting the lacunar infarcts in the basal ganglionic area. Lacunar infarcts in both acute and chronic stages tended to be larger on T2-weighted images than T1-weighted images. In 7 patients who had neither history of hypertension, diabetes mellitus, or cardiac emboli nor CT evidence, MRI was capable of detecting lacunar infarcts. (N.K.)

Using combined individual patient data from prospective studies, we explored sex differences in depression and prognosis post-myocardial infarction (MI) and determined whether disease indices could account for found differences. Individual patient data analysis of 10,175 MI patients who completed diagnostic interviews or depression questionnaires from 16 prospective studies from the MINDMAPS study was conducted. Multilevel logistic and Cox regression models were used to determine sex differences in prevalence of depression and sex-specific effects of depression on subsequent outcomes. Combined interview and questionnaire data from observational studies showed that 36% (635/1760) of women and 29% (1575/5526) of men reported elevated levels of depression (age-adjusted odds ratio = 0.68, 95% confidence interval [CI] = 0.60-0.77). The risk for all-cause mortality associated with depression was higher in men (hazard ratio = 1.38, 95% CI = 1.30-1.47) than in women (hazard ratio = 1.22, 95% CI = 1.14-1.31; sex by depression interaction: p < .001). Low left ventricular ejection fraction (LVEF) was associated with higher depression scores in men only (sex by LVEF interaction: B = 0.294, 95% CI = 0.090-0.498), which attenuated the sex difference in the association between depression and prognosis. The prevalence of depression post-MI was higher in women than in men, but the association between depression and cardiac prognosis was worse for men. LVEF was associated with depression in men only and accounted for the increased risk of all-cause mortality in depressed men versus women, suggesting that depression in men post-MI may, in part, reflect cardiovascular disease severity.

Caring for an older adult with memory loss is stressful. Caregiver stress could produce negative outcomes such as depression. Previous research is limited in examining multiple intermediate pathways from caregiver stress to depressive symptoms. This study addresses this limitation by examining the role of self-efficacy, social support, and problem solving in mediating the relationships between caregiver stressors and depressive symptoms. Using a sample of 91 family caregivers, we tested simultaneously multiple mediators between caregiver stressors and depression. Results indicate that self-efficacy mediated the pathway from daily hassles to depression. Findings point to the importance of improving self-efficacy in psychosocial interventions for caregivers of older adults with memory loss.

An 82-year-old woman with a history of asthma was admitted to our hospital because of dyspnea. On admission, laboratory testing showed a white blood cell count of 17,700/μl with hypereosinophilia of 9,204/μl (52% of all white blood cells). Various examinations, including a bone marrow biopsy for the cause of eosinophilia, were unremarkable. The patient was diagnosed with hypereosinophilic syndrome (HES). Treatment with intravenous methylprednisolone was initiated. The patient's eosinophil count normalized within 1 day. On the 6th day, she developed left-sided hemiparesis. Magnetic resonance imaging (MRI) of the brain showed acute multiple infarcts in arterial border zones of bilateral cerebral and cerebellar hemispheres, and in bilateral basal ganglia and the thalamus. Magnetic resonance angiography was normal. Coagulation factors were normal, except for an elevated D-dimer level (12.9 μg/ml). A transthoracic echocardiogram showed thickening of the left ventricular endocardium with immobile thrombus, compatible with Löffler endocarditis. Treatment with oral prednisolone was started at 30 mg/day and then tapered to a maintenance dose of 5 mg/day. Anticoagulation was concurrently started for prevention of stroke. Ten months later, an echocardiogram showed that the thrombus had decreased in size, and MRI revealed no new cerebral infarctions. The cause of cerebral infarction in patients with hypereosinophilia is thought to be thromboembolism or cerebrovascular endothelial toxicity of eosinophils. In this patient, the cerebral infarcts may have been the result of embolism from the left ventricular thrombus. Because HES with Löffler endocarditis is frequently associated with a poor prognosis, cardiovascular problems should be evaluated and treatment started as soon as possible.

Depression and chronic fatigue are frequently present in multiple sclerosis (MS); however, the prevalence rates have not been investigated in neuromyelitis optica (NMO). Thirty-nine consecutive NMO and 75 MS patients were compared using self-rating questionnaires for depressive states, daily activity, and fatigue, as well as serum carnitine levels. A subgroup of patients with low carnitine levels were re-evaluated regarding depression and fatigue after levocarnitine treatment. Depression and fatigue were equally prevalent in MS and NMO and were strongly correlated with one another. Measurement of the serum carnitine levels and the administration of levocarnitine did not appear to be beneficial. Copyright © 2015 Elsevier B.V. All rights reserved.

We tested the hypothesis that frequency analysis of the anatomic zones affected by single anterior (A), posterior (P), and middle (M) cerebral artery (CA), multivessel, and watershed infarcts will disclose specific sites (peak zones) most frequently involved by each type, sites most frequently injured by multiple different types (vulnerable zones), and overlapping sites of equal relative frequency for two or more different types of infarct (equal frequency zones). We adopted precise definitions of each vascular territory. CT and MRI studies of 50 MCA, 20 ACA-MCA, three PCA-MCA, and 30 parasagittal watershed infarcts were mapped onto a standard template. Relative infarct frequencies in each zone were analyzed within and across infarct types to identify the centers and peripheries of each, vulnerable zones, and equal frequency zones. These data were then correlated with the prior analysis of 47 ACA, PCA, dual ACA-PCA, and ACA-PCA-MCA infarcts. Zonal frequency data for MCA and watershed infarcts, the sites of peak infarct frequency, the sites of vulnerability to diverse infarcts, and the overlapping sites of equal infarct frequency are tabulated and displayed in standardized format for direct comparison of different infarcts. This method successfully displays the nature, sites, and extent of individual infarct types, illustrates the shifts in zonal frequency and lesion center that attend dual and triple infarcts, and clarifies the relationships among the diverse types of infarct.

Depression is more common among persons with multiple sclerosis (MS) than the general population. Depression in MS is associated with reduced quality of life, transition to unemployment, and cognitive impairment. Two proposed screening measures for depression in MS populations are the Hospital Anxiety and Depression Scale (HADS) and the Beck Depression Inventory-Fast Screen (BDI-FS). Our objective was to compared the associations of the BDI-FS and the HADS-D scores with history of depressive symptoms, fatigue, and functional outcomes to determine the differential clinical utility of these screening measures among persons with MS. We reviewed charts of 133 persons with MS for demographic information; scores on the HADS, BDI-FS, a fatigue measure, and a processing speed measure; and employment status. Structural equation modeling results indicated the HADS-D predicted employment status, disability status, and processing speed more effectively than did the BDI-FS, whereas both measures predicted fatigue. This study suggests the HADS-D is more effective than the BDI-FS in predicting functional outcomes known to be associated with depression among persons with MS.

Previous research has examined the components of depression and fatigue in multiple sclerosis (MS), but the findings have been inconsistent. The aim of this study was to explore the associations between overall and subscale scores of the Center for Epidemiologic Studies-Depression Scale (CES-D) and the Modified Fatigue Impact Scale (MFIS) as well as the longitudinal changes in scores in a large cohort of MS patients. MS subjects who completed a battery of patient reported outcome (PRO) measures including the CES-D and MFIS (N=435) were included in our analysis. At the first available MFIS measurement, Pearson's correlation coefficient was used to estimate the association between the CES-D and MFIS in terms of both total scores and subscale scores. In addition, the longitudinal change in each total score and subscale score was estimated using a linear mixed model, and the association between the measures in terms of longitudinal change was estimated using Pearson's correlation coefficient and linear mixed models. At baseline, 15% of subjects were classified as high on both depression and fatigue scales, 16% were classified as high on the fatigue scale only, and 9% were classified as high on the depression scale only. There was a high correlation between CES-D and MFIS total scores (r=0.62). High correlations were also observed between the somatic and retarded activity subscales of the CES-D and each of the MFIS subscales (r≥0.60). In terms of longitudinal change, the change over the first year between the CES-D and MFIS total scores showed a moderate correlation (r=0.49). Subjects with high fatigue scores but low depression scores at baseline were more likely than subjects with low baseline fatigue and depression scores to develop high depression scores at follow-up. Our study demonstrated that depression and fatigue in MS share several features and have a similar longitudinal course. But using cut-off scores to define depression and fatigue, our study also found

Bariatric surgery has been shown to be a safe and effective intervention for patients with comorbid obesity and multiple sclerosis (MS); however, this sub-population may be at heightened risk for pre- and postoperative depressive symptoms. This current exploratory study aims to describe the prevalence and nature of depressive symptoms in a sample of patients with MS who undergo bariatric surgery. Medical records were retrospectively reviewed to identify patients who received bariatric surgery and had a diagnosis of MS (n = 31) and a control sample of non-surgical MS patients with severe obesity (n = 828). Longitudinal outcome measures included the Patient Health Questionnaire-9 (PHQ-9) and Multiple Sclerosis Performance Scale (MSPS). There were no significant differences in PHQ-9 total and item scores between groups at baseline. PHQ-9 scores significantly improved at years 1 (p bariatric surgery when compared to non-surgical controls. Higher BMI (p = 0.03) and worse overall quality of life (p bariatric group. When compared to controls, the bariatric group demonstrated improved MSPS scores on a trend level 1 year post-surgery (p = 0.08). Consistent with the literature on more general bariatric surgery populations, current findings highlight the possible early benefits of bariatric surgery for reducing depressive symptoms in this population when compared to controls. Importantly, results should be viewed as preliminary and additional research is needed to examine bariatric surgery and associations with depressive symptoms and performance in the MS population.

Full Text Available Background: Myocardial infarction (MI is one of the major causes of death and disability worldwide, which can reduces quality of life in patients. Some disabilities are depression and anxiety which delay returning to work. The aim of this study was to evaluate the effect of illness perception focused intervention on quality of life, anxiety, and depression in MI patients. Materials and Methods: A randomized controlled trial study of 48 recently hospitalized MI patients was conducted (24 in intervention group and 24 in control group. Intervention group was trained to understand the disease by a mental health counselor in three half-an-hour sessions for three consecutive days. Data were collected from three questionnaires: hospital anxiety and depression scale, the World Health Organization Quality of Life Questionnaire (short form, and Illness Perceptions Questionnaire Brief at admission, 1.5, and 3 months postdischarge. Data were analyzed with ANOVA repeated measure. Results: The mean duration of returning to work was 28.7 ± 8.1 days in intervention groups and 46 ± 7.6 days in control group which was statistically significant (P < 0.001. Moreover, anxiety, depression, and illness perceptions score were significantly decreased in intervention groups which were 8.3 ± 3.3, 6.8 ± 3.5, and 36.5 ± 5 in intervention groups and 15.8 ± 2.1(P < 0.001, 17.1 ± 2.3 (P < 0.001, and 41.9 ± 4 (P < 0.001 in control group, respectively. Mean of quality of life subscales scores just physical health subscale showed a significant reduction after 3 months in the control group. Conclusion: Training MI patients to understand the disease in three half-an-hour sessions for 3 consecutive days can decrease the duration of returning to work, anxiety and depression, and increase illness perceptions which can make a better outcome.

Full Text Available We herein report the fourth case of cerebral infarction, concomitant with hemorrhagic shock, in English literature. A 33-year-old male, who had been diagnosed with schizophrenia and given a prescription for Olanzapine, was discovered with multiple self-inflicted bleeding cuts on his wrist. On arrival, he was in hemorrhagic shock without verbal responsiveness, but his vital signs were normalized following infusion of Lactate Ringer′s solution. The neuroradiological studies revealed multiple cerebral ischemic lesions without any vascular abnormality. He was diagnosed with speech apraxia, motor aphasia, and dysgraphia, due to multiple cerebral infarctions. As there was no obvious causative factor with regard to the occurrence of cerebral infarction in the patient, the hypoperfusion due to hemorrhagic shock, and the thromboembolic tendency due to Olanzapine, might have acted together to lead to the patient′s cerebral ischemia.

Full Text Available Objective: The common sexual complains in patients with coronary heart disease and post myocardial infarction are decrease in libido, impotence, and premature or delay ejaculation. Cardiac rehabilitation could decrease many of the psychological features of myocardial infarction and also increase exercise capacity of patients. Rehabilitation may also improve sexual disturbances in these patients directly or indirectly. This study is a clinical trial that evaluate the effect of rehabilitation on sexual problem of post MI patients. Materials & Methods: 60 patients took part in this study. All of them were men aged between 35 and 65. All patients had myocardial infarction one month ago. 30 patients were referred for cardiac rehabilitation (Case, and 30 people were patients who were not recommended to take part in rehabilitation because their physician did not believe on rehabilitation. Questioner for anxiety, depression, impotency, libido and premature ejaculation were evaluated by before and after study period. The cardiac rehabilitation composed of 24 sessions. Each session consisted of one hour of aerobic exercise (10 min warm up, 10 min cool down and 40 min isotonic exercise. Results: After cardiac rehabilitation the scores for anxiety, depression, premature ejaculation and impotency were decreased and the scores of libido were increased. In both case and control groups, the changes were significant by paired t test P<0.05. The differences between case and control were significant for depression, libido and impotency by independent t test. Conclusion: Cardiac rehabilitation could improve sexual problems in post myocardial infarction patients directly and indirectly by effect on psychological characteristics.

To determine if overprotection on the part of the patient's family and friends contributes to the development of cardiac invalidism after acute myocardial infarction. Longitudinal survey. Nine hospitals in the southwestern United States. One hundred eleven patients who had experienced a first acute myocardial infarction. Subjects were predominantly male, older-aged, married, caucasian, and in functional class I. Eighty-one patients characterized themselves as being overprotected (i.e., receiving more social support from family and friends than desired), and 28 reported receiving inadequate support. Only two patients reported receiving as much support as they desired. Self-esteem, emotional distress, health perceptions, interpersonal dependency, return to work. Overprotected patients experienced less anxiety, depression, anger, confusion, more vigor, and higher self-esteem than inadequately supported patients 1 month after myocardial infarction (p Overprotection on the part of family and friends may facilitate psychosocial adjustment in the early months after an acute myocardial infarction rather than lead to cardiac invalidism.

Electrocardiographic changes of acute lateral wall myocardial infarction: a reappraisal based on scintigraphic localization of the infarct

Movahed, A.; Becker, L.C.

1984-01-01

To determine how often acute lateral myocardial infarcts may be electrocardiographically silent, a new approach was utilized in which subjects were selected by admission thallium scintigraphy. Thirty-one patients with their first infarction were identified with moderate to severe perfusion defects of the lateral and posterolateral walls, persistent over 7 days and associated with severe wall motion abnormalities. Patients with involvement of the anterior, septal or inferior regions were not included. In nine patients, the perfusion defect extended to the anterolateral wall: all developed ST elevation and Q waves in at least one of the lateral leads (I, aVL or V6) but none showed changes in the inferior leads (II, III or aVF). In the other 22 patients, the perfusion defect was limited to the lateral and posterolateral walls: only 12 showed ST elevations (inferior leads only in 7, lateral leads only in 2, both leads in 3) and only 9 developed Q waves (inferior in all). In 8 of these 22 patients, the infarct was silent in the sense that no ST segment elevation or Q waves were seen, although ST depressions or T wave inversions, or both, in all but one patient were compatible with subendocardial infarction. The results indicate that the standard electrocardiogram is insensitive to changes in the lateral and posterolateral regions. Additional diagnostic studies are needed for proper localization and sizing of acute myocardial infarcts

The CT scans and the clinical records of 12 patients who had renal infarction were reviewed. The renal infarcts were classified as either focal or global. The CT findings were correlated with the etiologies of renal infarction. Embolism was the most common cause of renal infarcts that were multifocal with involvement of both kidneys. Trauma caused a unilateral global type of infract. A case of sickle cell anemia presented with multiple ''slit-like'' focal infarcts and enlarged kidneys. Forty-seven per cent of infarcts demonstrated the cortical rim sign, 11% were acapsular fluid collection, and 6% had an abnormally thickened renal fascia

Justification for intravenous magnesium therapy in acute myocardial infarction

DEFF Research Database (Denmark)

Rasmussen, H S

1988-01-01

Recent studies have shown that patients with acute myocardial infarction (AMI) are magnesium-deficient and develop an additional transient decrease in serum magnesium concentrations (S-Mg c) during the acute phase of the infarct. Animal experiments, as well as studies on humans, have indicated.......v. magnesium therapy on mortality and incidence of arrhythmias in patients with AMI has been evaluated. Magnesium treatment more than halved the acute mortality and incidence of arrhythmias requiring treatment in three of the four intervention studies. The mechanisms behind the beneficial effect of magnesium...... therapy are probably multifactorial; a direct depressive effect on the cardiac conducting system; a peripheral dilatory effect on the arteries, reducing the afterload on the myocardium; a reduced infarct size; an ion-stabilizing effect, maintaining stable intra and extracellular concentrations...

A Case of Turner Syndrome with Multiple Embolic Infarcts

2016-09-01

Full Text Available Only a few cases of Turner syndrome (TS with ischemic stroke have been reported. Various arteriopathies of the cerebral arteries, including fibromuscular dysplasia, congenital hypoplasia, moyamoya syndrome, and premature atherosclerosis have been assumed to be the cause of ischemic stroke in TS. There has been no case report of a TS patient presenting with an embolic stroke pattern without any cerebral arteriopathy. A 28-year-old woman with TS was referred to our hospital because of abnormal brain magnetic resonance imaging (MRI findings. She underwent brain MRI at the referring hospital because she experienced sudden-onset diffuse headache. Diffusion-weighted imaging revealed multiple acute embolic infarcts in different vascular territories. Intracranial and extracranial arterial disease was not detected on cerebral magnetic resonance angiography and carotid sonography. Embolic source workups, including transthoracic and transesophageal echocardiography, Holter monitoring, and transcranial Doppler shunt study, were all negative. Hypercoagulability and vasculitis panels were also negative. Our patient was diagnosed with cryptogenic embolic stroke. This is the first report of a TS patient with an embolic stroke pattern. Our case shows that ischemic stroke in TS could be due to embolism as well as the various cerebral arteriopathies documented in previous reports.

Noguchi, K.; Nagayoshi, T.; Watanabe, N.; Kanazawa, T.; Toyoshima, S.; Morijiri, M.; Shojaku, H.; Shimizu, M.; Seto, H.

1998-01-01

We studied 35 patients with lacunar infarcts, using diffusion-weighted echo-planar imaging (DW-EPI) at 1.5 T. The relative apparent diffusion coefficient ratio (ADCR) of each lesion was calculated and lesion conspicuity on DW-EPI was compared to that on images aquired with fast fluid-attenuated inversion recovery and T2-weighted fast spin-echo sequences. Acute small infarcts (within 3 days) were identified with DW-EPI as an area of decreased ADCR (range 0.33-0.87; mean 0.67) and high signal, subacute small infarcts (4-30 days) as a high-signal or isointense areas of decreased or nearly normal ADCR (0.54-0.98; 0.73), and chronic small infarcts (> 30 days) as low- or high-signal areas of nearly normal or increased ADCR (0.97-1.92; 1.32). In three patients, small infarcts of the brain stem in the hyperacute phase (within 6 h) were seen only with DW-EPI. In five patients, fresh small infarcts adjacent to multiple old infarcts could be distinguished only with DW-EPI. (orig.)

Vargas, Gray A; Arnett, Peter A

2013-01-01

Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS in 52 patients with MS to test the LH theory in this population and to determine possible differences between illness-related and non-illness-related attributions. Patients were administered measures of attributional style, daily stressors, disability, and depressive symptoms. Participants were more likely to list non-MS-related than MS-related causes of negative events on the Attributional Style Questionnaire (ASQ), and more-disabled participants listed significantly more MS-related causes than did less-disabled individuals. Non-MS-related attributional style correlated with stress and depressive symptoms, but MS-related attributional style did not correlate with disability or depressive symptoms. Stress mediated the effect of non-MS-related attributional style on depressive symptoms. These results suggest that, although attributional style appears to be an important construct in MS, it does not seem to be related directly to depressive symptoms; rather, it is related to more perceived stress, which in turn is related to increased depressive symptoms.

2016-07-01

Full Text Available A 35-year-old man of average build and a smoker, with a background of a psychiatric disorder, was brought by his neighbor to the emergency department after an hour of severe chest pain. Upon arrival at the hospital he had cardiac arrest, was resuscitated, and moved to the catheterization laboratory with inferior, posterior, and lateral myocardial infarction. Coronary angiography showed an unusual thrombosis in multiple coronary branches. Toxicology report showed high levels of amphetamines and benzodiazepines in the patient’s original blood sample. The patient was kept under ventilation for 18 days, with difficult recovery due to severe withdrawal manifestations, ventilation acquired pneumonia, and rhabdomyolysis inducing acute renal failure. The patient regained near normal left ventricular function after baseline severe regional and global dysfunction. We postulate a relationship between the use of amphetamines, potentiated by benzodiazepines, and occurrence of acute thrombosis of multiple major coronary arteries.

Omega-3 Fatty Acids for Depression in Multiple Sclerosis: A Randomized Pilot Study.

Directory of Open Access Journals (Sweden)

Lynne Shinto

Full Text Available Multiple sclerosis is the most common chronic disabling disease in the central nervous system in young to middle aged adults. Depression is common in multiple sclerosis (MS affecting between 50–60% of patients. Pilot studies in unipolar depression report an improvement in depression when omega-3 fatty acids are given with antidepressants. The objective of this study was to investigate whether omega-3 fatty acid supplementation, as an augmentation therapy, improves treatment-resistant major depressive disorder (MDD in people with MS. We performed a randomized, double-blind, placebo-controlled pilot study of omega-3 fatty acids at six grams per day over three months. The primary outcome was a 50% or greater improvement on the Montgomery-Asberg Depression Rating Scale (MADRS. Thirty-nine participants were randomized and thirty-one completed the 3-month intervention. Improvement on MADRS between groups was not significantly different at the 3-month end point with 47.4% in the omega-3 fatty acid group and 45.5% in the placebo group showing 50% or greater improvement (p = 0.30. Omega-3 fatty acids as an augmentation therapy for treatment-resistant depression in MS was not significantly different than placebo in this pilot trial. Omega-3 fatty acid supplementation at the dose given was well-tolerated over 3 months.ClinicalTrials.gov NCT00122954.

Multiple infarcted regenerative nodules in liver cirrhosis after decompensation of cirrhosis: a case series

Müllhaupt Beat

2010-11-01

Full Text Available Abstract Introduction Liver cirrhosis is a common disease with many known complications. Cirrhosis represents a clinical spectrum, ranging from asymptomatic liver disease to hepatic decompensation. Manifestations of hepatic decompensation include variceal bleeding, ascites, hepatic encephalopathy, hepatorenal syndrome, hepatopulmonary syndrome, portopulmonary hypertension and hepatocellular carcinoma. There are reports about infarcted regenerative nodules in cirrhotic livers after gastrointestinal hemorrhage. Case presentation We report three Caucasian patients (one female and two male patients; ages: 52, 54 and 60 years with decompensated liver cirrhosis, who showed newly infarcted regenerative nodules at necropsy. Two of them suffered from gastric variceal bleeding. Histopathology showed extensive infarction in all three cases. Hemorrhage and inflammatory changes were also observed around the infarcted regenerative nodules. Conclusion These patients showed focal liver lesions, to be considered in the differential diagnosis of cirrhotic livers. Infarcted regenerative nodules may be underdiagnosed in patients with decompensation of cirrhosis. In order to differentiate these lesions from malignant tumors, serial imaging seems to be helpful. However, the main differential diagnosis should be an abscess. It is important to know the wide spectrum of image appearances of these lesions. Hypotension can lead to a reduction of portal and arterial liver flow. Since variceal bleeding or septic shock can induce hypotension - as observed in our patients - we conclude that this leads to infarction of such nodules.

Recent literature has indicated that exposure to multiple traumatic events in adults is associated with high levels of posttraumatic stress disorder (PTSD), anxiety, and depression. Against the backdrop of stressful life events and childhood abuse and neglect, we investigated the cumulative effect of multiple trauma exposure on PTSD, anxiety, and depression in an adolescent sample. One thousand one hundred forty 10th-grade learners from 9 Cape Town (South Africa) schools completed questionnaires on stressful life experiences; trauma exposure; and symptoms of anxiety, depression, and PTSD. Our population of interest for this study was adolescents between the ages of 14 and 18 years who had been exposed to serious, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, qualifying traumatic events. The final sample size was thus 922. Rates of trauma exposure, PTSD, depression, and anxiety were high. Controlling for sex, stressful life experiences in the past year, and childhood adversity, we found an effect of cumulative trauma exposure effect on PTSD and depression, with an increase in the number of traumas linearly associated with an increase in symptoms of PTSD (F((4,912)) = 7.60, P cumulative effect on anxiety. Our findings indicate that adolescents exposed to multiple traumas are more likely to experience more severe symptoms of PTSD and depression than those who experience a single event, with this effect independent of childhood adversity and everyday stressful life experiences. Exposure to multiple trauma, however, does not seem to be associated with more severe anxiety symptoms.

Full Text Available Introduction. Acute myocardial infarction is life-threatening. A cardiac troponin rise accompanied by typical symptoms, ST elevation or depression is diagnostic of acute myocardial infarction. Here, we report an unusual case of a female who was admitted with chest pain. However, she did not present with a typical profile of an acute myocardial infarction patient. Case Presentation. A 66-year-old Han nationality female presented with chest pain. The electrocardiogram (ECG revealed arched ST segment elevations and troponin was elevated. However, the coronary angiography showed a normal coronary arterial system. Thyroid function tests showed that this patient had severe hyperthyroidism. Conclusion. Our case highlights the possibility that hyperthyroidism may cause a large area of myocardium injury and ECG ST segment elevation. We suggest routine thyroid function testing in patients with chest pain.

A longitudinal analysis of cognitive dysfunction, coping, and depression in multiple sclerosis.

Science.gov (United States)

Rabinowitz, Amanda R; Arnett, Peter A

2009-09-01

Using a longitudinal design, the authors examined coping and cognitive functioning in the development of depression in individuals with multiple sclerosis (MS). Coping style was evaluated in 2 conceptually distinct roles: as moderator and mediator of the impact of cognitive dysfunction on depression. Using indices derived from the COPE (C. S. Carver, M. F. Scheier, & J. K. Weintraub, 1989), the authors operationalized coping in 3 ways-as active, avoidant, and an index accounting for relative levels of both. Coping both moderated and partially mediated the relationship between cognitive dysfunction and depression. Moderation results suggest that the relationship between cognitive dysfunction and depression is dependent on coping style-adaptive coping protects individuals from experiencing depression related to their cognitive deficits; however, when individuals use maladaptive coping, cognitive dysfunction puts them at risk for depression. Mediational results suggest that cognitive dysfunction leads to depression partially due to cognitive dysfunction's effects on coping. That is, cognitive deficits may impair individuals' ability to use adaptive coping strategies, leaving them more likely to use maladaptive strategies. Clinical and theoretical implications of these findings are discussed.

Depression and coronary artery disease -real heart attack

Farooqi, S.; Ahmed, B.

2001-01-01

Both depression and ischaemic heart disease are said to become the leading causes of morbidity and mortality in developing countries during the next two decades. The relationship between these two disorders has long been speculated but only recently addressed scientifically. A Medline search was conducted to obtain the articles that address the association between depressive disorders and coronary artery disease (CAD). Most studies following large cohorts over a period ranging from 4.5 to 27 years have shown that depression is associated with a significantly high risk of developing CAD. These studies also show that patients who have depression following myocardial infarction hat poorer prognosis on major cardiac end points like reoccurrence of myocardial infarction and death as compared to the non-depressed group. The psychosocial variables associated with depression like social isolation, acute and chronic stressful life events are also associated with increased risk of developing CAD. The mechanisms underlying this association between depression and CAD are unknown at present. The effectiveness of psychosocial interventions in reducing this increased risks have been demonstrated while the trials assessing the efficacy and safety of anti depressed drugs are underway. The implications of these finding are discussed in the context of developing countries. (author)

The purpose of our work was to determine a prevalence of depression and its distribution by grades in patients with a coronary heart disease, namely - with the myocardial infarction. The study involved 125 patients of average age 64.2±4.7 years, treated at cardiology department for myocardial infarction. The first stage was a depression screening using PHQ - 2 questionnaire. In case of positive answer to at least one question, we assessed the severity of depression using a PHQ-9 tool. We established, that PHQ-2 questionnaire questions for screening depressive disorders were positively answered by 80 patients (64.3%). Total signs of depression of various severity grades was diagnosed in 68 patients (54.4%). Minimal depression was diagnosed in 25 (36.8%) patients, mild depression - in 20 (29.4%) patients, moderately severe disease - in 16 (23.6%) patients, and severe depression - in 7 (10.2%) patients. The severity of depression was clearly related to age, gender of patients, comorbid diseases, and a history of MI and revascularization.

2010-04-01

Full Text Available Abstract Introduction Hereditary causes of visceral thrombosis or thrombosis should be sought among young patients. We present a case of a young man presenting with multiple hepatic infarctions resulting in portal hypertension due to homozygosity of the prothrombin gene mutation not previously described in literature. Case presentation A 42-year-old Caucasian man with a previous history of idiopathic deep vein thrombosis 11 years earlier presented with vague abdominal pains and mildly abnormal liver function tests. An ultrasound and computed tomography scan showed evidence of hepatic infarction and portal hypertension (splenic varices. A thrombophilia screen confirmed a homozygous mutation for the prothrombin gene mutation, with mildly reduced levels of anti-thrombin III (AT III. Subsequent testing of his father and brother revealed heterozygosity for the same gene mutation. Conclusion Hepatic infarction is unusual due to the rich dual arterial and venous blood supply to the liver. In the absence of an arterial or haemodynamic insult causing hepatic infarction, a thrombophilia should be considered. To our knowledge, this is the first reported case of a hepatic infarction due to homozygosity of the prothrombin gene mutation. It is unclear whether homozygotes have a higher risk of thrombosis than heterozygotes. In someone presenting with a first thrombosis with this mutation, the case for life-long anticoagulation is unclear, but it may be necessary to prevent a second and more severe second thrombotic event, as occurred in this case.

We evaluated right and left ventricular function in the case of myocardial infarction (MI) by radionuclide cardioangiography. The right and left ventricular ejection fraction (RVEF, LVEF) and ventricular volume (RVEDV, LVEDV) were calculated. And, phase and amplitude images were also obtained from gated blood pool scan. There were 60 cases of MI (35 anterior MI, 17 inferior MI and 8 right ventricular MI) and 10 normal cases. The LVEF was depressed in anterior MI (36 +- 14%) and RVEF was depressed in right ventricular MI (37 +- 5%). In addition, LVEDV was increased in anterior MI (163 +- 47 ml) and RVEDV increased in right ventricular MI (208 +- 33 ml), respectively. The amplitude of infarcted area was decreased. And the phase angle of LV was delayed in anterior MI and that of RV was delayed in right ventricular MI. Therefore, in the case of right ventricular MI, the depression of LVEF and RVEF was caused by the biventricular myocardial damage. And the cross talk phenomenon of biventricle was rarely observed, since the lung acts as the buffer between RV and LV. In conclusion, these noninvasive, methods provide useful information on the biventricular function in the case of myocardial infarction. (author)

Iodine-123 single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI) were undertaken in 8 patients with Alzheimer's disease (AD) and 7 patients with multiple infarct dementia (MID). Imaging features and their relationship to neuropsychologic findings were examined. The group of AD patients had markedly decreased activity in the bilateral parietal-occipital areas on SPECT and relatively marked atrophy in the corresponding area and thinning in the posterior part of callosal stem on MRI. The group of MID patients had a widespread and inhomogeneously decreased activity in the frontal lobe and mottled decrease of activity in the other cortical areas on SPECT. Neuropsychologic symptoms steming from the parietal-occipital area, which is considered as an causative area for AD, were frequently observed in the AD group, as opposed to the lack of these symptoms in the MID group. In both AD and MID groups, there was a good correlation between the areas with decreased activity on SPECT and atrophy on MRI. These imaging appearances were correlated with the occurrence of neuropsychologic symptoms as well. The importance of the parietal-occipital lobe that is likely responsible for the pathogenesis of dementia for AD is emphasized. (Namekawa, K.)

Asymptomatic lacunar infarcts are often found in the Brain Dock. The presence of asymptomatic lacunar infarcts increases the risk of serious cerebral infarction. Thus, it is an important task for radiologists and/or neurosurgeons to detect asymptomatic lacunar infarctions in MRI images. However, it is difficult for radiologists and/or neurosurgeons to identify lacunar infarcts correctly in MRI images, because it is hard to distinguish between lacunar infarcts and enlarged Virchow-Robin space. Therefore, the purpose of our study was to develop a computer-aided diagnosis scheme for detection of lacunar infarctions in order to assist radiologists and/or neurosurgeons' interpretation as a ''second opinion.'' Our database consisted of 1143 T2-weighted MR images and 1143 T1-weighted MR images, which were selected from 132 patients. First, we segmented the cerebral parenchyma region by use of a region growing technique. The white-tophat transformation was then applied for enhancement of lacunar infarcts. The multiple-phase binarization was used for identifying initial candidates of lacunar infarcts. For removal of false positives (FPs), 12 features were determined in each of the initial candidates in T2 and T1-weighted MR images. The rule-based schemes and an artificial neural network with these features were used for distinguishing between lacunar infarcts and FPs. The sensitivity of detection of lacunar infarcts was 96.8% (90/93) with 0.69 (737/1063) FP per image. This computerized method may be useful for radiologists and/or neurosurgeons in detecting lacunar infracts in MRI images. (author)

Eosinophilic granulomatosis with polyangiitis (EGPA, previously named Churg-Strauss syndrome) is a form of necrotizing vasculitis occurring in patients with asthma and eosinophilia. Ischemic stroke is a relatively rare complication of the disease. We report a case of a 63-year-old woman with multiple embolic infarcts, hypereosinophilia (for >7 years), and skin rash. Elevated cardiac enzymes and cardiac magnetic resonance imaging were consistent with endomyocarditis. The simultaneous presence of history of asthma, sinusitis, hypereosinophilia, and vasculitis led to the diagnosis of EGPA. This case contributes to the recent debate of the 2 possible presentations of the disease according to the ANCA (antineutrophil cytoplasmic antibodies) status. We furthermore underscore the need for careful differential diagnosis of the "ANCA negative" cases with persistent hypereosinophilia from the idiopathic hypereosinophilic syndrome.

Full Text Available Background: One of the factors that could influence the quality of life in patients with multiple sclerosis, which is usually overlooked, is its psychological aspects. Considering the increasing acceptance of complementary medicine in the health system, this study was designed and conducted to determine the effect of group cognitive therapy on the stress, anxiety, and depression of women suffering from multiple sclerosis. Materials and Methods: This clinical trial was conducted among 70 women suffering from multiple sclerosis who were referred to the health centers of Isfahan. Participants were randomly allocated into two groups of intervention and control, each containing 35 patients. The intervention group received cognitive behavioral therapy as 8 90-minute group sessions (a session per week, and the control group participated in 4 group sessions to express their feelings and experiences. Data were gathered using the Depression Anxiety Stress Scale (DASS-24. Results: There was a significant difference between the mean score of stress (P = 0.03, anxiety (P = 0.02, and depression (P = 0.03 of the intervention and the control group immediately after and 1 month after the intervention. Least squares difference test showed that the mean score of stress (P = 0.02, anxiety (P = 0.02, and depression (P = 0.03 immediately and 1 month after the intervention was significantly lower in the intervention group. Conclusions: According to the results of the present study, cognitive behavioral therapy could decrease stress, anxiety, and depression in patients suffering from multiple sclerosis.

Cerebral autosomal dominant arteriopathy with sub cortical infarcts and leucoencephalopathy (CASADIL) is a systemic hereditary, vascular disease that involves small arteries. Recurrent ischemia, pseudo bulbar paralysis and dementia are characteristic. Other manifestations include migraine and depression. We report an Argentine family with VI generations with evidence of disease in IV. MR examinations were performed on 21 family members (both symptomatic and asymptomatic). The main findings on MR on symptomatic and asymptomatic patients were small lesions with high signal on T2 localised in periventricular white matter, brain stem, basal ganglia and thalamus, and confluent patches on white matter although with high signal on T2 images, usually symmetric. In conclusion we can assess that diffuse myelin loss and small infarcts occurring in cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy well demonstrated with MR. In addition, some of the abnormalities in pre symptomatic patients can be identified on MR images. (author)

Depressive symptoms are common in multiple sclerosis (MS), and both depression and MS have been associated with a poor vitamin D status. As cytokine-mediated inflammatory processes play a role in the pathogenesis of both disorders, we hypothesized that vitamin D 3 supplementation reduces depressive symptoms in MS via its immunomodulatory properties. In this randomized pilot study relapsing remitting (RR) MS patients received either vitamin D 3 supplementation (n=20; 14.000IU/day) or placebo (n=20) during 48weeks. Pre- and post-supplementation depression scores, measured using the Hospital Anxiety Depression Scale (HADS) depression subscale (HADS-D), showed a significant decrease within the vitamin D 3 group (median HADS-D 4.0 to 3.0, p=0.02), a trend towards a decrease within the placebo group (median HADS-D 3.0 to 2.0, p=0.06), but no significantly different reductions between groups (p=0.78). Furthermore, no reductions in pro- and anti-inflammatory cytokine balances, secreted by stimulated leukocytes and CD8 + T cells, were found in the vitamin D 3 compared to the placebo arm. Therefore, we found no evidence for a reduction of depressive symptoms or related biomarkers upon vitamin D 3 supplementation in RRMS patients in this exploratory study. Whether vitamin D 3 supplementation is of benefit in manifest depression in MS needs to be assessed by additional studies. Copyright © 2017 Elsevier B.V. All rights reserved.

The relationship between war-related trauma exposure, depressive symptoms and multiple risk behaviors among adolescents is less clear in sub-Saharan Africa. We analyzed data collected from a sample of school-going adolescents four years postwar. Participants completed interviews assessing various risk behaviors defined by the Youth Self Report (YSR) and a sexual risk behavior survey, and were screened for post-traumatic stress, anxiety and depression symptoms based on the Impact of Events Scale Revised (IESR) and Hopkins Symptom Checklist for Adolescents (HSCL-37A) respectively. Multivariate logistic regression was used to assess factors independently associated with multiple risk behaviors. The logistic regression model of Baron and Kenny (1986) was used to evaluate the mediating role of depression in the relationship between stressful war events and multiple risk behaviors. Of 551 participants, 139 (25%) reported multiple (three or more) risk behaviors in the past year. In the multivariate analyses, depression symptoms remained uniquely associated with multiple risk behavior after adjusting for potential confounders including socio-demographic characteristics, war-related trauma exposure variables, anxiety and post-traumatic stress symptoms. In mediation analysis, depression symptoms mediated the associations between stressful war events and multiple risk behaviors. The psychometric properties of the questionnaires used in this study are not well established in war affected African samples thus ethno cultural variation may decrease the validity of our measures. Adolescents with depression may be at a greater risk of increased engagement in multiple risk behaviors. Culturally sensitive and integrated interventions to treat and prevent depression among adolescents in post-conflict settings are urgently needed. © 2013 Elsevier B.V. All rights reserved.

Previous analyses showed that a telephone-based intervention to increase physical activity in individuals with multiple sclerosis (MS) and depression resulted in significantly improved depressive symptoms compared to a wait-list control group. The aim of this study was to test positive affect and negative affect as mediators of the effect of the physical activity counseling on depressive symptoms. Ninety-two adults with MS, who met diagnostic criteria for either major depression or dysthymia and who reported low levels of physical activity, were randomized 1:1 to a 12-week telephone-based motivational interviewing (MI) intervention to improve physical activity (n = 44) or to a 12-week wait-list control group (n = 48). Self-reported positive and negative affect, physical activity, and depressive symptoms were gathered at baseline and postintervention. Path-analysis was used to test whether positive affect and negative affect mediated the positive effects of the intervention on depressive symptoms. Both positive and negative affect were significant mediators of the effects of the intervention on depressive symptoms; however, only positive affect mediated the association between changes in physical activity and improved depressive symptoms. Findings support physical activity and positive affect as key mediators of the MI treatment effect on improved mood. Decreases in negative affect were also evident in the treatment group, but were not related to improved physical activity. Findings may suggest the use of exercise-based interventions in conjunction with treatments that specifically target negative affective mechanisms for depression.

Cognitive impairment and depression frequently affects patients with multiple sclerosis (MS). However, the relationship between the occurrence of depression and cognitive impairment and the development of cortical atrophy has not been fully elucidated yet. To investigate the association of cortical and deep gray matter (GM) volume with depression and cognitive impairment in MS. Three-dimensional (3D) T1-weighted scans were obtained from 126 MS patients and 59 matched healthy controls. Cognitive impairment was assessed using the Brief Repeatable Battery of Neuropsychological Tests and depression with the Montgomery-Asberg Depression Rating Scale (MADRS). Using FreeSurfer and FIRST software, we assessed cortical thickness (CTh) and deep GM volumetry. Magnetic resonance imaging (MRI) variables explaining depression and cognitive impairment were investigated using factorial and classification analysis. Multivariate regression models correlated GM abnormalities with symptoms severity. Compared with controls, MS patients exhibited widespread bilateral cortical thinning involving all brain lobes. Depressed MS showed selective CTh decrease in fronto-temporal regions, whereas cognitive impairment MS exhibited widespread fronto-parietal cortical and subcortical GM atrophy. Frontal cortical thinning was the best predictor of depression ( C-statistic = 0.7), whereas thinning of the right precuneus and high T2 lesion volume best predicted cognitive impairment ( C-statistic = 0.8). MADRS severity correlated with right entorhinal cortex thinning, whereas cognitive impairment severity correlated with left entorhinal and thalamus atrophy. MS-related depression is linked to circumscribed CTh changes in areas deputed to emotional behavior, whereas cognitive impairment is correlated with cortical and subcortical GM atrophy of circuits involved in cognition.

Multiple sclerosis is a chronic disease considered the major cause of neurological disability in young adults worldwide. While depression is considered a determinant factor of impaired quality of life and poorer prognosis among patients with multiple sclerosis, it is very often dismissed and undertreated by physicians. Depression has been related to treatment with some immunomodulatory drugs, such as IFNβ. Data from patients who committed suicide during the pivotal study of interferon used as a disease modifying treatment in multiple sclerosis support this association. Moreover, there is plenty of evidence of neuropsychiatric toxicity caused by the use of IFNα as a treatment for other medical conditions. Although this link still remains relatively unknown, the presence of warnings regarding the possible relationship between depression and IFNβ led to restriction in medical indications in these patients. The purpose of this paper is to try to understand the reasons for an increased prevalence in depression in multiple sclerosis and to examine the impact that IFNβ treatment has on their mood. We performed a literature search on MEDLINE and Google Scholar databases applying PRISMA guidelines for systematic reviews. Studies were included if the participants were diagnosed with MS and prescribed IFNβ as the main treatment. We excluded non-english and full-text non available papers, as well as the articles where mental health was assessed exclusively as a feature of quality of life. The sample includes articles from 1980 to 2014, although filtration by year of publication was not applied and contains data from IFNβ-1a and IFNβ-1b. The Cochrane Collaboration Tool assessing risk of bias was used to determine the quality of the studies. Ten studies met full criteria for inclusion and final data extraction. The articles have heterogeneity regarding the samples, the methodology used and the expression of the results. Only three studies support the evidence of a

Reciprocal ST-depression in the electrocardiograms (ECGs) of patients with ST-elevation myocardial infarction (STEMI) results from either true ischemia at a distance via collateral circulation diverting blood to the infarcted region or an electrical phenomenon that results from a mirror reflection of ST-elevation. We aimed to identify the role of reciprocal ECG changes in predicting collateral circulation to the infarcted area determined angiographically. In a retrospective study, ECG and angiography of 53 STEMI patients admitted to SUNY Upstate Medical University in 2014 were reviewed independently by experts blinded to the results of ECG and coronary angiography. Reciprocal changes (RC) in ECG were present in 41 patients (77%) and on angiography, 14 patients (26%) exhibited collateral vessels to the ischemic areas. No correlation was found between the presence of RC and collateral circulation (P = 0.384), or between the depth of reciprocal ST-depression and the degree of the collateral circulation (P = 0.195). However, 84% of patients without collaterals exhibited resolution of RC after successful percutaneous coronary intervention (PCI) (P = 0.036), suggesting that the ST depressions that resolved after reperfusion were directly caused by the culprit vessel. Patients without RC presented late after symptom onset (9.25 versus 3.83 hours, P = 0.004), also suggesting time related resolution. RC had no relation to or predictive value for collaterals on angiography. Among late presenting patients, RC were less frequent. Thus, reciprocal ST-depression may represent subendocardial ischemia from the primary coronary event or simply an electrical phenomenon, rather than ischemia at distance from impaired collateral circulation.

2016-09-01

Multiple sclerosis (MS) is one of the most common diseases of the central nervous system and usually occurs at the age when people would be expected to be in the prime of their sexual lives. In everyday practice, sexual dysfunction is underestimated because clinicians mostly concentrate on the classic neurologic deficits and often overlook symptoms that can seriously affect the quality of life. Our study included 98 patients (42 men and 56 women, mean age 35±12 years) with relapse from our MS register, with established diagnosis of relapsing remitting multiple sclerosis according to McDonald criteria. Patients completed the questionnaires (Sexual Satisfaction Scale, SSS and Beck Depression Scale BDS), and underwent neurological assessment (Expanded Disability Status Scale, EDSS). All patients were in the group with EDSS 2 to 4 points (mobile patients). There was no statistically significant difference in BDS and SSS values according to EDSS score. Correlation coefficients were calculated (BDS and SSS) for men (p=0.42) and women (p=0.44), yielding positive correlation. There was no statistically significant difference in BDS and SSS values according to gender, disease duration or immunomodulatory therapy. In our group of patients, despite low EDSS score (fully ambulatory without aid, self sufficient patients) we found positive correlation between sexual dysfunction and depression, showing that even in such patients the quality of life can be decreased. In conclusion, sexual dysfunction and depression are mostly under-recognized by neurologists because they are not part of routine testing; therefore, some additional questionnaires should be used in the evaluation in MS patients, even those with low EDSS score, in order to improve their quality of life.

A 65-year-old man presented with fluctuating focal neurological deficits and neuroimaging findings of multiple small cerebral infarctions. His medical investigation revealed a >100 pack/year smoking history, and a haematocrit >60. Subsequent investigations led to a diagnosis of cerebral infarction due to smoker’s polycythemia, the third such case reported in the medical literature. The patient’s neurological deficits resolved completely with subsequent haematocrit reduction. This brief report reviews the differential diagnosis of polycythemia, current knowledge of the mechanisms by which smoker’s polycythemia may lead to ischemic stroke, and recommendations for management.

In 12 patients with acute myocardial infarction, a dual isotope SPECT was applied to describe a myocardial infarct map for detecting the site and the extent of the infarct. Threshold cut-off level was determined as 55 % for [ 99m Tc] and 35 % for [ 201 Tl] according to cardiac phantom studies. Multiple cardiac tomograms showed two different uptakes of the isotopes in indentical slices and regions. Then, color tomograms were described on the red and green image for [ 99m Tc] and for [ 201 Tl], respectively, and Bulls eye map was drawn in the two colored fashion as the myocardial infarct map. In all patients, the infarct map was successful to determine the exact site of the infarct and the overlapped area by the viable myocardium. In conclusion, this functional map of acute myocardial infarction may be useful for understanding three dimensional area of the infarct and the viable myocardium easily and exactly. (author)

Alcohol induced spontaneous osteonecrosis is part of the differential diagnosis in patients with history of alcohol abuse and diffuse bone pain. Usually patients have a longer than 10 year history of alcohol abuse prior to the development of osteonecrosis. The femoral head is the commonest site involved, however, involvement of the long bones is also seen. Facial involvement is rarely seen. Fat embolism secondary to coexisting hyperlipidemia has been postulated as a possible cause of osteonecrosis in alcoholics. A case of multifocal spontaneous bone infarction with facial bone involvement in a 34 year old female alcoholic is described.

Full Text Available Abstract Background To study the rules that apparent diffusion coefficient (ADC changes with time and space in cerebral infarction, and to provide the evidence in defining the infarction stages. Methods 117 work-ups in 98 patients with cerebral infarction (12 hyperacute, 43 acute, 29 subacute, 10 steady, and 23 chronic infarctions were imaged with both conventional MRI and diffusion weighted imaging. The average ADC values, the relative ADC (rADC values, and the ADC values or rADC values from the center to the periphery of the lesion were calculated. Results The average ADC values and the rADC values of hyperacute and acute infarction lesion depressed obviously. rADC values in hyperacute and acute stage was minimized, and increased progressively as time passed and appeared as "pseudonormal" values in approximately 8 to 14 days. Thereafter, rADC values became greater than normal in chronic stage. There was positive correlation between rADC values and time (P Conclusion The ADC values of infarction lesions have evolution rules with time and space. The evolution rules with time and those in space can be helpful to decide the clinical stage, and to provide the evidence in guiding the treatment or judging the prognosis in infarction.

Prognostic relevant pathways of leukocyte involvement in human myocardial ischemic-reperfusion injury are largely unknown. We enrolled 136 patients with ST-elevation myocardial infarction (STEMI) after primary angioplasty within 12 h after onset of symptoms. Following reperfusion, whole blood was collected within a median time interval of 20 h (interquartile range: 15-25 h) for genome-wide gene expression analysis. Subsequent CMR scans were performed using a standard protocol to determine infarct size (IS), area at risk (AAR), myocardial salvage index (MSI) and the extent of late microvascular obstruction (lateMO). We found 398 genes associated with lateMO and two genes with IS. Neither AAR, nor MSI showed significant correlations with gene expression. Genes correlating with lateMO were strongly related to several canonical pathways, including positive regulation of T-cell activation (p = 3.44 × 10 -5 ), and regulation of inflammatory response (p = 1.86 × 10 -3 ). Network analysis of multiple gene expression alterations associated with larger lateMO identified the following functional consequences: facilitated utilisation and decreased concentration of free fatty acid, repressed cell differentiation, enhanced phagocyte movement, increased cell death, vascular disease and compensatory vasculogenesis. In conclusion, the extent of lateMO after acute, reperfused STEMI correlated with altered activation of multiple genes related to fatty acid utilisation, lymphocyte differentiation, phagocyte mobilisation, cell survival, and vascular dysfunction.

Previous findings suggest that apathy symptoms independently of depressive symptoms measured using the Geriatric Depression Scale (GDS) are associated with cardiovascular disease (CVD) in older individuals. To study whether apathy and depressive symptoms in older people are associated with future CVD, stroke, and mortality using individual patient-data meta-analysis. Medline, Embase, and PsycInfo databases up to September 3, 2013, were systematically searched without language restrictions. We sought prospective studies with older (mean age ≥65 years) community-dwelling populations in which the GDS was employed and subsequent stroke and/or CVD were recorded to provide individual participant data. Apathy symptoms were defined as the three apathy-related subitems of the GDS, with depressive symptoms the remaining items. We used myocardial infarction (MI), stroke, and all-cause mortality as main outcomes. Analyses were adjusted for age, sex, and MI/stroke history. An adaptation of the Newcastle-Ottawa scale was used to evaluate bias. Hazard ratios were calculated using one-stage random-effect Cox regression models. Of the 52 eligible studies, 21 (40.4%) were included, comprising 47,625 older people (mean age [standard deviation] 74 [7.4] years), over a median follow-up of 8.8 years. Participants with apathy symptoms had a 21% higher risk of MI (95% confidence interval [CI] 1.08-1.36), a 37% higher risk of stroke (95% CI 1.18-1.59), and a 47% higher risk of all-cause mortality (95% CI 1.38-1.56). Participants with depressive symptoms had a comparably higher risk of stroke (HR 1.36, 95% CI 1.18-1.56) and all-cause mortality (HR 1.44, 95% CI 1.35-1.53), but not of MI (HR 1.08, 95% CI 0.91-1.29). Associations for isolated apathy and isolated depressive symptoms were comparable. Sensitivity analyses according to risk of bias yielded similar results. Our findings stress the clinical importance of recognizing apathy independently of depressive symptoms, and could help

Full Text Available Background. A variant form of angina pectoris (VAP is caused by coronary vessel spasm and occures in patients with and without varying degrees of obstructive coronary artery disease. Although the prognosis of VAP without significant organic stenosis is generally good, multivessel spasm is associated with a high risk of life-threatening abnormalities of rhythm and conduction.Patient and methods. We describe a patient who presented with prolonged chest pain, associated with hypotension, lost of consciousness, complete AV block and widespread ST segment elevations consistent with inferoanterior acute myocardial infarction. Urgent selective coronary angiography revealed spasms in right coronary artery and in left circumflex artery that were relieved by intracoronary injection of nitroglycerin. All coronary arteries were otherwise patient, without signs of atherosclerosis. The patient was treated with diltiazem and nitrates. She made a complete recovery and resumed her normal activities.Conclusions. Simultaneous multiple spasms of native coronary arteries represent a rare syndrome characterized by significantly higher incidence of potentially life-threatening arrhythmia. Less commonly, prolonged coronary spasm may mimic acute myocardial infarction. Modern management of acute coronary syndromes, including urgent coronarography, enables a prompt differentiation between prolonged coronary spasm and atherosclerotic coronary disease, warranting different treatment strategies. Medical treatment with nitrates and calcium channel blockers in most cases prevents recurrence of vasospasms and arrhythmias.

Multiple angioscopic yellow plaques are associated with diffuse atherosclerotic plaque, and may be prevalent in patients with myocardial infarction (MI), so in the present study the yellow plaques in the coronary arteries of patients with MI was evaluated using quantitative colorimetry, and compared with those of patients with stable angina (SA). In the recorded angioscopic images of 3 coronary vessels in 29 patients (15 patients with MI, 14 with SA), yellow plaques were determined as visually yellow regions with b* value >0 (yellow color intensity) measured by the quantitative colorimetric method. A total of 90 yellow plaques were identified (b* =19.35+/-8.3, 3.05-45.35). Yellow plaques were significantly more prevalent in 14 (93%) of 15 culprit lesions of MI as compared with 8 (57%) of 14 of SA (p=0.03). In non-culprit segments, yellow plaques were similarly prevalent in 13 (87%) patients with MI and 11 (79%) with SA (p=0.65). Overall, multiple (> or =2) yellow plaques were prevalent in 13 (87%) patients with MI, similar to the 10 (71%) with SA (p=0.38). The number of yellow plaques was significantly higher in patients with MI (3.8+/-1.9) than in those with SA (2.4+/-1.6, p=0.03). The present study suggests that patients with MI tend to have diffuse atherosclerotic plaque in their coronary arteries.

We studied to know the relation between right ventricular function and infarct-related artery after acute myocardial infarction. The right and left ventricular function after a first myocardial infarction was assessed ECG-gated blood pool single photon emission computed tomography (GBPS) algorithms (Cedars-Sinai Medical Center, Los Angels, Calif) (12 after LAD related infarction (group 1) and 15 after RCA related infarction (group 2)). The left ventricular ejection fraction, end-diastolic volume and end-systolic volume did not differ significantly between two groups( group 1 vs 2 :LVEF 50.8% vs 55.1%. LVEDV=73.2 vs 79.7 ml, LVESV=38 vs 44 ml : P>0.05), but right ventricular ejection fraction, end-diastolic volume and end-systolic volume were significantly different after anterior myocardial infarction between two groups( group 1 vs 2 : RVEF=57.3% vs 46.3%. RVEDV=56.4 vs 95.1 ml, RVESV=25.6 vs 54.6ml : P<0.05). There was evidence of right ventricular dilatation in the group with RCA related infarction. Six with inferior infarction had abnormal right ventricular ejection fractions (< 40%). The relation between right and left ventricular ejection fractions was markedly different in the two groups. In the group with RCA related infarction there was a significant linear relation between right and left ventricular ejection fraction(R=0.5). Whereas in the group with LAD related infarction there was not (R=-0.3). Thus right ventricular dysfunction commonly occurs after RCA related infarction. Right ventricular impairment is related after RCA related infarction, but are independent after LAD related infarction. Finally, the different effects of LAD and RCA related infarction on right ventricular function may be explained by site of the myocardial wall involvement after infarction

During summer, near drowning is a common accident in Taiwan. It may lead to multiple organ damages in cases where severe hypothermia and hypoxemia occur. We present a case of myocardial infarction after near drowning. The patient was sent to our ED by the emergency medical services called by the witness. On arrival to our ED, hypothermia and hypoxemia overcame him. Endotracheal intubation and warm intravenous fluid were applied at once owing to drowsy consciousness, respiratory distress, and hypothermia. Electrocardiogram showed diffuse ST-segment elevation over the precordial leads V2-V6. The initial level of cardiac enzymes was within normal limit but elevated in troponin I on the second day after hospitalization. We presumed that the possibility of myocardial infarction resulted from near drowning-related hypoxemia. To our knowledge, this is the first case describing myocardial injury with electrocardiogram changes after near drowning.

Depressive symptoms are common in individuals with multiple sclerosis (MS), and are frequently exacerbated by pain; however, spiritual well-being may allow persons with MS to more effectively cope with pain-related deficits in physical and role functioning. We explored the associations between spiritual well-being, pain interference and depressive symptoms, assessing each as a potential mediator, in eighty-one patients being treated for MS, who completed self-report measures: Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale, Pain Effects Scale, and Center for Epidemiologic Studies Depression Scale Revised. At the bivariate level, spiritual well-being and its subscale of meaning and peace were negatively associated with depression and pain interference. In mediation models, depression was not related to pain interference via spiritual well-being, or to spiritual well-being via pain interference. Pain interference was related to depression via spiritual well-being and meaning/peace, and to spiritual well-being and meaning/peace via depressive symptoms. Finally, spiritual well-being and meaning/peace were related to depression via pain interference, and to pain interference via depressive symptoms. For patients with MS, a multi-faceted approach to treatment that includes pain reduction and promotion of spiritual well-being may be beneficial, although amelioration of depression remains a critical task.

Multiple sclerosis (MS) is a chronic progressive autoimmune disease impacting both body and mind. Typically, patients with MS report fatigue, depression, and paresthesia. Standard treatment consists of immune modulatory medication, though there is growing evidence that exercising programs have a positive influence on fatigue and psychological symptoms such as depression. We tested the hypothesis that, in addition to the standard immune regulatory medication, either yoga or aquatic exercise can ameliorate both fatigue and depression, and we examined whether these interventions also influence paresthesia compared with a nonexercise control condition. Fifty-four women with MS (mean age: M = 33.94 yr, SD = 6.92) were randomly assigned to one of the following conditions: yoga, aquatic exercise, or nonexercise control. Their existing immune modulatory therapy remained unchanged. Participants completed questionnaires covering symptoms of fatigue, depression, and paresthesia, both at baseline and on completion of the study 8 wk later. Compared with the nonexercise control condition and over time, fatigue, depression, and paresthesia decreased significantly in the yoga and aquatic exercise groups. On study completion, the likelihood of reporting moderate to severe depression was 35-fold higher in the nonexercise control condition than in the intervention conditions (yoga and aquatic exercising values collapsed). The pattern of results suggests that for females with MS and treated with standard immune regulatory medication, exercise training programs such as yoga and aquatic exercising positively impact on core symptoms of MS, namely, fatigue, depression, and paresthesia. Exercise training programs should be considered in the future as possible complements to standard treatments.

Full Text Available Clinically significant depression can impact up to 50% of patients with multiple sclerosis (MS over a course of their life time, which is associated with an increased morbidity and mortality. In our study, fifteen relapsing-remitting MS (RRMS patients and 15 age- and gender-matched normal controls were included. Diffusion tensor imaging (DTI was acquired by employing a single-shot echo planar imaging sequence on a 3.0 T MR scanner and fractional anisotropy (FA was performed with tract-based spatial statistics (TBSS approach. Finally, widespread WM and GM abnormalities were observed in RRMS patients. Moreover, the relationships between the depressive symptoms which can be measured by Hamilton depression rating scale (HAMD as well as clinical disabilities measured by the expanded disability status scale (EDSS and FA changes were listed. There was a positive relation between EDSS and the FA changes in the right inferior parietal lobule, while negative relation was located in the left anterior cingulate cortex and hippocampus. Also a positive relation between HAMD and FA changes was found in the right posterior middle cingulate gyrus, the right hippocampus, the left hypothalamus, the right precentral gyrus, and the posterior cingulate which demonstrated a link between the depressive symptoms and clinically relevant brain areas in RRMS patients.

AIM: To study if impaired renal function is associated with increased risk of peri-infarct heart failure (HF) in patients with preserved ejection fraction (EF). METHODS: Patients with occluded infarct-related arteries (IRAs) between 1 to 28 d after myocardial infarction (MI) were grouped into chronic kidney disease (CKD) stages based on estimated glomerular filtration rate (eGFR). Rates of early post-MI HF were compared among eGFR groups. Logistic regression was used to explore independent predictors of HF. RESULTS: Reduced eGFR was present in 71.1% of 2160 patients, with significant renal impairment (eGFR < 60 mL/min every 1.73 m2) in 14.8%. The prevalence of HF was higher with worsening renal function: 15.5%, 17.8% and 29.4% in patients with CKD stages 1, 2 and 3 or 4, respectively (P < 0.0001), despite a small absolute difference in mean EF across eGFR groups: 48.2 ± 10.0, 47.9 ± 11.3 and 46.2 ± 12.1, respectively (P = 0.02). The prevalence of HF was again higher with worsening renal function among patients with preserved EF: 10.1%, 13.6% and 23.6% (P < 0.0001), but this relationship was not significant among patients with depressed EF: 27.1%, 26.2% and 37.9% (P = 0.071). Moreover, eGFR was an independent correlate of HF in patients with preserved EF (P = 0.003) but not in patients with depressed EF (P = 0.181). CONCLUSION: A significant proportion of post-MI patients with occluded IRAs have impaired renal function. Impaired renal function was associated with an increased rate of early post-MI HF, the association being strongest in patients with preserved EF. These findings have implications for management of peri-infarct HF. PMID:20885993

Patients with Depression and the acute coronary syndrome (ACS) is rarely detected, although in some studies say that depression can worsen cardiovascularly and increase mortality. From research, Canan F et al found that increasing levels of Mean platelet volume (MPV) as a risk factor for atherosclerosis and MPV was higher in patients with depression compared with patients without depression. In this study used observational methods of measurement of cross-sectional data. Research began in November 2015 - May 2016 against General Hospital inpatients H. Adam Malik Medan. There are 64 patients with a diagnosis of ACS were given quieter Beck Depression Inventory (BDI), then calculated a score of BDI patients and MPV levels were seen when they first entered the hospital before being given treatment. Patients answered quieter on days 3-7 after diagnosis ACS. ACS Patients were divided into 3 groups: acute myocardial infarction with ST elevation, acute myocardial infarction with non-ST elevation and unstable angina pectoris. The level of depression is grouped into not depression, mild depression, moderate depression and severe depression. Statistically significant with p-value<0.05Based on the linear correlation analysis, it was found a positive correlation with r=0.542. And the relationship is statistically significant with p-value 0.000003.

Simultaneous assessment of regional myocardial perfusion and local contraction ability of interoposterior myocardial infarction was examined by ECG gated SPECT. In thirteen cases of acute interoposterior myocardial infarction, the above-mentioned data were obtained by 180deg data acquisition method using L-shaped 2 detecting element type gamma camera. Mean and standard deviation of %Uptake and wall thickening (WT) in inferior wall were as follows: Infarction case; 57±9.2%/23±11.3%, normal case; 71±8.2%/61±10.2%. The significant depression (p<0.01/p<0.001) of both data were found in the infarction case. The both data in posterior wall were as follows: Infarction case; 55±10.7%/16±8.9%, normal case; 64±9.7%/41±15.0%. The significant depression (p<0.05/p<0.001) were also found in the infarction case. In both inferior wall and posterior wall, the AUC of ROC curve of WT was greater than that of %Uptake, and diagnostic ability of this method was favorable. The best sensitivity/specificity rate and the threshold were as follows: %Uptake of inferior wall 77/65, -0.5SD, WT of inferior wall 100/100, -2SD, %Uptake of posterior wall 62/82, -1SD, WT of posterior wall 85/88, -4SD. Accordingly, in diagnosis of interoposterior myocardial infarction, assessment of focus cardiac function, for example WT, is necessary as well as %Uptake. (K.H.)

Full Text Available Objectives. We studied whether the amount of dental calculus is associated with death from heart infarction in the dental infection—atherosclerosis paradigm. Materials. Participants were 1676 healthy young Swedes followed up from 1985 to 2011. At the beginning of the study all subjects underwent oral clinical examination including dental calculus registration scored with calculus index (CI. Outcome measure was cause of death classified according to WHO International Classification of Diseases. Unpaired t-test, Chi-square tests, and multiple logistic regressions were used. Results. Of the 1676 participants, 2.8% had died during follow-up. Women died at a mean age of 61.5 years and men at 61.7 years. The difference in the CI index score between the survivors versus deceased patients was significant by the year 2009 (P<0.01. In multiple regression analysis of the relationship between death from heart infarction as a dependent variable and CI as independent variable with controlling for age, gender, dental visits, dental plaque, periodontal pockets, education, income, socioeconomic status, and pack-years of smoking, CI score appeared to be associated with 2.3 times the odds ratio for cardiac death. Conclusions. The results confirmed our study hypothesis by showing that dental calculus indeed associated statistically with cardiac death due to infarction.

Full Text Available Abstract Background Decompressive hemicraniectomy is a life-saving procedure for patients with malignant middle cerebral artery infarctions. However, the neuropsychological sequelae in such patients have up to now received little attention. In this study we not only describe neuropsychological deficits but also the quality of life and the extent of depression and other psychiatric symptoms in patients after complete media infarction of the non-speech dominant hemisphere. Methods 20 patients from two different university hospitals (mean ± standard deviation: 52 ± 14 years of age who had undergone hemicraniectomy with duraplasty above the non-speech dominant hemisphere at least one year previously were examined using a thorough neurological and neuropsychological work-up. The quality of life and the extent of psychiatric problems were determined on the basis of self-estimation questionnaires. The patients were asked whether they would again opt for the surgical treatment when considering their own outcome. 20 healthy persons matched for age, gender and education served as a control group. Results All patients but one were neurologically handicapped, half of them severely. Age was significantly correlated with poorer values on the Rankin scale and Barthel index. All cognitive domain z values were significantly lower than in the control group. Upon re-examination, 18 of 20 patients were found to be cognitively impaired to a degree that fulfilled the formal DSM IV criteria for dementia. Conclusions Patients with non-speech dominant hemispheric infarctions and decompressive hemicraniectomy are at high risk of depression and severe cognitive impairment.

This cross-sectional study aims to identify the predictors of work-related difficulties in a sample of employed persons with multiple sclerosis as addressed with the Multiple Sclerosis Questionnaire for Job Difficulties. Hierarchical linear regression analysis was conducted to identify predictors of work difficulties: predictors included demographic variables (age, formal education), disease duration and severity, perceived disability and psychological variables (cognitive dysfunction, depression and anxiety). The targets were the questionnaire's overall score and its six subscales. A total of 177 participants (108 females, aged 21-63) were recruited. Age, perceived disability and depression were direct and significant predictors of the questionnaire total score, and the final model explained 43.7% of its variation. The models built on the questionnaire's subscales show that perceived disability and depression were direct and significant predictors of most of its subscales. Our results show that, among patients with multiple sclerosis, those who were older, with higher perceived disability and higher depression symptoms have more and more severe work-related difficulties. The Multiple Sclerosis Questionnaire for Job Difficulties can be fruitfully exploited to plan tailored actions to limit the likelihood of near-future job loss in persons of working age with multiple sclerosis. Implications for rehabilitation Difficulties with work are common among people with multiple sclerosis and are usually addressed in terms of unemployment or job loss. The Multiple Sclerosis Questionnaire for Job Difficulties is a disease-specific questionnaire developed to address the amount and severity of work-related difficulties. We found that work-related difficulties were associated to older age, higher perceived disability and depressive symptoms. Mental health issues and perceived disability should be consistently included in future research targeting work-related difficulties.

Major depression and depressive symptoms are common in patients with a recent myocardial infarction (MI), and depression is associated with adverse cardiovascular outcomes. Anxiety post-MI is less studied, but occurs commonly in patients with heart disease, and is also considered a risk factor for recurrence of cardiac events. Cognitive behavior therapy (CBT) is an established therapy for depression and anxiety disorders. To the best of our knowledge, there have not been any studies to determine if internet-based CBT (iCBT) can reduce the symptoms of depression and anxiety in patients with a recent MI. The main aim of the U-CARE Heart trial is to evaluate an iCBT intervention for patients with a recent MI. This is a randomized, controlled, prospective study with a multicenter design. A total of 500 participants will be randomized at a 1:1 ratio, around two months after an acute MI, to either iCBT or to a control group. Both groups will receive an optimal standard of care according to guidelines. The intervention consists of a self-help program delivered via the internet with individual online support from a psychologist. Treatment duration is 14 weeks. The primary outcome is change in patients' self-rated anxiety and depression symptoms from baseline to end of treatment. An internal pilot study was conducted indicating sufficient levels of study acceptability and engagement in treatment. The present study is designed to evaluate an iCBT intervention targeting symptoms of depression and anxiety in a post-MI population. If effective, iCBT has several advantages, and will potentially be implemented as an easily accessible treatment option added to modern standard of care. This trial was registered with Clinicaltrials.gov (identifier: NCT01504191 ) on 19 December 2011.

Objective: To explore the relationship between the presence and severity of post-MI depression and the increased inflammatory activity, as marked by the serum levels of interleukin-6 (IL-6) and C-reactive protein (CRP) after myocardial infarction. Methods: Serum IL-6 and CRP levels were measured in 58 AMI patients within 36 hours after onset of event. Depression was evaluated by self-reporting standardized questionnaire, using a validated Chinese version of Hospiatla Anxiety and Depression Scale (HADS)-Depression Subscale (7 items) within 7 days. Demographic and medical data including LVEF, NYHA cardiac function grading, atherosclerosis severity shown from angiography as well as cardiac risk factors were recorded. Results: Serum levels of IL-6 and CRP were higher in depressive AMI patients than those in non-depressive ones (0.93 ± 0.64 vs 0.48 ± 0.37 ng/L, P<0.05 and 0.96 ± 0.41 vs 0.47 ± 0.26 mg/dL, P<0.05). Neither levels of IL-6 nor HADS-D scores were found to be correlated to the severity of atherosclerosis shown in angiography. Conclusion: Presence and severity of post-MI depression is associated with increased activity of inflammation in patients after myocardial infarction. (authors)

Depressed cardiac pump function is the hallmark of congestive heart failure, and it is suspected that decreased influx of Ca2+ into the cardiac cell is responsible for depressed contractile function. Since Ca2+ channels in the sarcolemmal membrane are considered to be an important route for the entry of Ca2+, we examined the status of Ca2+ receptors/channels in failing rat hearts after myocardial infarction of the left ventricular free wall. For this purpose, the left coronary artery was ligated and hearts were examined 4, 8, and 16 weeks later; sham-operated animals served as controls. Hemodynamic assessment revealed decreased total mechanical energy (left ventricular systolic pressure x heart rate), increased left ventricular diastolic pressure, and decreased positive and negative dP/dt in experimental animals at 4, 8, and 16 weeks. Although accumulation of ascites in the abdominal cavity was evident at 4 weeks, other clinical signs of congestive heart failure in experimental rats were evident from the presence of lung congestion and cardiac dilatation at 8 and 16 weeks after induction of myocardial infarction. The density of Ca2+ receptors/channels in crude membranes, as assessed by [3H]nitrendipine binding assay, was found to be decreased in the uninfarcted experimental left ventricle at 8 and 16 weeks; however, no change in the affinity of nitrendipine was evident. A similar depression in the specific binding of another dihydropyridine compound, [3H]PN200-110, was also evident in failing hearts. Brain and skeletal muscle crude membrane preparations, unlike those of the right ventricle and liver, revealed a decrease in Ca2+ receptors/channels density in experimental animals at 16 weeks

Bee sting is one of the most commonly encountered insect bites in the world. Despite the common occurrence of local and systemic allergic reactions, there are few reports of ischemic stroke after bee stings. To the best our knowledge, there have been no reports on involuntary hyperkinetic movement disorders after multiple bee stings. We report the case of a 50-year-old man who developed involuntary movements of the left leg 24 hours after multiple bee stings, and the cause was confirmed to be a right temporal infarction on a diffusion magnetic resonance imaging scan. Thus, we concluded that the involuntary movement disorder was caused by right temporal infarction that occurred after multiple bee stings.

Full Text Available Purpose: Mindfulness interventions have been shown to treat depressive symptoms and improve quality of life in patients with several chronic diseases, including multiple sclerosis, but to date most evaluation of the effectiveness of mindfulness interventions in multiple sclerosis have used patients receiving standard care as the control group. Hence we decided to evaluate the effectiveness of a group-based body-affective mindfulness intervention by comparing it with a psycho-educational intervention, by means of a randomized controlled clinical trial. The outcome variables (i.e., depression, anxiety, perceived stress, illness perception, fatigue and quality of life were evaluated at the end of the interventions (T1 and after a further 6 months (T2.Methods: Of 90 multiple sclerosis patients with depressive symptoms (Beck Depression Inventory-II score greater than 13 who were randomized, 71 completed the intervention (mindfulness group n = 36; psycho-educational group n = 35. The data were analyzed with GLM repeated-measures ANOVA followed by pairwise comparisons.Results: Per-protocol analysis revealed a time by group interaction on Beck Depression Inventory-II score, with the mindfulness intervention producing a greater reduction in score than the psycho-educational intervention, both at T1 and at T2. Furthermore, the mindfulness intervention improved patients’ quality of life and illness perception at T1 relative to the baseline and these improvements were maintained at the follow-up assessment (T2. Lastly, both interventions were similarly effective in reducing anxiety and perceived stress; these reductions were maintained at T2. A whole-sample intention-to-treat (ITT analysis broadly confirmed the effectiveness of the mindfulness intervention.Conclusion: In conclusion, these results provide methodologically robust evidence that in multiple sclerosis patients with depressive symptoms mindfulness interventions improve symptoms of depression

The purpose of this study was to investigate the correlation between platelet aggregability and silent brain infarcts. The study subjects were 445 people (264 men, 181 women; mean age, 53±14 years) with no neurologic signs, history of brain tumor, trauma, cerebrovascular disease, or antiplatelet medications. Adenosine diphosphate (ADP)-induced platelet aggregation was measured by the aggregation-size analytic method. Platelet aggregability was classified into 9 classes. The presence of headache/vertigo, hypertension, diabetes mellitus, hyperlipidemia, or smoking was elicited by questioning or blood sampling. A head MRI scan was performed, and if marked atherosclerosis or obvious stenosis in the intracranial vessels was detected, it was defined as a positive MR angiography (MRA) finding. Silent brain infarcts were detected in 26.3% of subjects. Hyperaggregability defined as that above class 6, 7, and 8 was present in 43.8%, 30.8%, and 15.7% of subjects, respectively. The risk factors for silent brain infarcts by multiple logistic regression analysis were aging, hypertension, positive MRA findings, and hyperaggregability. Platelet ADP hyperaggregability might be a risk factor for silent brain infarcts. (author)

Anxiety and depression are associated with an activation of coagulation and an impairment of fibrinolysis, which may contribute to the increased cardiovascular risk associated with the two disorders. However, very few studies have examined the impact of psychological distress on coagulation factors in coronary artery disease patients. The aim of this study was to assess the correlation between anxiety/depression and factors of coagulation and fibrinolysis in patients who had suffered an acute MI three months prior. In 148 patients, anxiety and depression were assessed by the Hospital Anxiety and Depression Scale (HADS) shortly after MI and three months later. At the second time of assessment, plasma levels of fibrinogen, factor VII, factor VIII, von Willebrand factor, prothrombin-fragment 1 and 2, tissue-plasminogen-activator, plasminogen activator inhibitor-1, D-dimer, and homocysteine were measured. In 32% of the patients, elevated levels of anxiety and depression were found three months after a MI. Multiple regression analyses showed that coagulation and fibrinolysis markers were not significantly associated with HADS anxiety and depression scores. We found that age, gender, BMI, and smoking status were significant predictors for haemostasis factors. A higher age was associated with a higher coagulability but lower anxiety levels. We measured parameters of coagulation and fibrinolysis in patients three months after MI and found no predictive value of HADS anxiety and depression scores shortly after MI or at the time of blood sampling. The effects of age on the relationship between anxiety and haemostasis should be further investigated. Copyright © 2017 Elsevier Inc. All rights reserved.

Purpose: To demonstrate the different patterns of renal infarction to avoid pitfalls. To present 'flip-flop enhancement' pattern in renal infarction. Materials and methods: Retrospective review of a total of 41 renal infarction in 37 patients were done. These patients underwent initial CT and the diagnosis of renal infarction was confirmed with either follow up CT or at surgery. Results: Twenty-three patients had wedge-shaped focal infarcts, nine patients had global and five patients had multifocal infarcts of the kidneys. Cortical rim sign was seen predominantly with global infarcts. In five patients, a 'flip-flop enhancement' pattern was observed. In two patients, planned renal biopsies due to tumefactive renal lesions were cancelled because of 'flip-flop enhancement' pattern on follow up CTs. Conclusion: Although most of our cases were straightforward for the diagnosis of renal infarction, cases with tumefactive lesions and global infarctions without the well-known cortical rim sign were particularly challenging. We describe a new sign, flip-flop enhancement pattern, which we believe solidified the diagnosis of renal infarction in five of our cases. The authors recommend further investigations for association of flip-flop enhancement and renal infarction

Predicting which patients are at risk for hemicraniectomy can be helpful for triage and can help preserve neurologic function if detected early. We evaluated basal ganglia imaging predictors for early hemicraniectomy in patients with large territory anterior circulation infarct. This retrospective study evaluated patients with ischemic infarct admitted from January 2005 to July 2011. Patients with malignant cerebral edema refractory to medical therapy or with herniating signs such as depressed level of consciousness, anisocoria, and contralateral leg weakness were triaged to hemicraniectomy. Admission images were reviewed for presence of caudate, lentiform nucleus (putamen and globus pallidus), or basal ganglia (caudate + lentiform nucleus) infarction. Thirty-one patients with large territory MCA infarct, 10 (32%), underwent hemicraniectomy. Infarction of the caudate nucleus (9/10 vs 6/21, p = 0.002) or basal ganglia (5/10 vs 2/21, p = 0.02) predicted progression to hemicraniectomy. Infarction of the lentiform nucleus only did not predict progression to hemicraniectomy. Sensitivity for patients who did and did not have hemicraniectomy were 50% (5/10) and 90.5% (19/21). For caudate nucleus and caudate plus lentiform nucleus infarcts, the crude- and age-adjusted odds of progression to hemicraniectomy were 9.5 (1.4-64.3) and 6.6 (0.78-55.4), respectively. Infarction of the caudate nucleus or basal ganglia correlated with patients progressing to hemicraniectomy. Infarction of the lentiform nucleus alone did not. (orig.)

To study the rules that apparent diffusion coefficient (ADC) changes with time and space in cerebral infarction, and to provide the evidence in defining the infarction stages. 117 work-ups in 98 patients with cerebral infarction (12 hyperacute, 43 acute, 29 subacute, 10 steady, and 23 chronic infarctions) were imaged with both conventional MRI and diffusion weighted imaging. The average ADC values, the relative ADC (rADC) values, and the ADC values or rADC values from the center to the periphery of the lesion were calculated. The average ADC values and the rADC values of hyperacute and acute infarction lesion depressed obviously. rADC values in hyperacute and acute stage was minimized, and increased progressively as time passed and appeared as 'pseudonormal' values in approximately 8 to 14 days. Thereafter, rADC values became greater than normal in chronic stage. There was positive correlation between rADC values and time (P < 0.01). The ADC values and the rADC values in hyperacute and acute lesions had gradient signs that these lesions increased from the center to the periphery. The ADC values and the rADC values in subacute lesions had adverse gradient signs that these lesions decreased from the center to the periphery. The ADC values of infarction lesions have evolution rules with time and space. The evolution rules with time and those in space can be helpful to decide the clinical stage, and to provide the evidence in guiding the treatment or judging the prognosis in infarction

Six patients with acute hemorrhagic brain infarct were imaged using spin-echo (SE) pulse sequences on a 1.5 Tesla MR scanner. Including two patients with repeated MR imaging, a total of eight examinations, all performed within 15 days after stroke, were analyzed retrospectively. Four patients revealed massive hemorrhages in the basal ganglia or cerebellum and three cases demonstrated multiple linear hemorrhages in the cerebral cortex. On T1-weighted images, hemorrhages were either mildly or definitely hyperintense relative to gray matter, while varied from mildly hypointense to hyperintense on T2-weighted images. T1-weighted images were superior to T2-weighted images in detection of hemorrhgage. CT failed to detect hemorrhage in two of five cases: indicative of MR superiority to CT in the diagnosis of acute hemorrhagic infarcts. (author)

Full Text Available Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL is a hereditary neurological disease accompanied by recurrent ischemic events, characterized by the presence of psychiatric disorders. The aim of this study was to examine the occurrence of depression and its severity among patients with CADASIL. Sixteen patients with diffuse white matter changes on MRI and clinical signs suggesting CADASIL were included in the study. Definitive diagnosis of CADASIL was obtained by electron microscopic analysis of skin biopsies. Testing of the patients’ affective status was primarily devoted to detecting depression. Electron microscopic examinations of all skin biopsies revealed numerous granular osmiophilic material (GOM deposits embedded into the basal lamina around altered or degenerated vascular smooth muscle cells (VSMCs. Clinical symptoms of depression were present in a great number of examined CADASIL patients. The frequency of depression was higher than previously reported. Psychiatric disturbances might also represent the onset of CADASIL, especially in young patients, and should be evaluated by differential diagnosis.

Patients with space-occupying hemispheric infarctions have a poor prognosis, with case fatality rates of up to 80%. In a pooled analysis of randomised trials, surgical decompression within 48 h of stroke onset reduced case fatality and improved functional outcome; however, the effect of surgery after longer intervals is unknown. The aim of HAMLET was to assess the effect of decompressive surgery within 4 days of the onset of symptoms in patients with space-occupying hemispheric infarction. Patients with space-occupying hemispheric infarction were randomly assigned within 4 days of stroke onset to surgical decompression or best medical treatment. The primary outcome measure was the modified Rankin scale (mRS) score at 1 year, which was dichotomised between good (0-3) and poor (4-6) outcome. Other outcome measures were the dichotomy of mRS score between 4 and 5, case fatality, quality of life, and symptoms of depression. Analysis was by intention to treat. This trial is registered, ISRCTN94237756. Between November, 2002, and October, 2007, 64 patients were included; 32 were randomly assigned to surgical decompression and 32 to best medical treatment. Surgical decompression had no effect on the primary outcome measure (absolute risk reduction [ARR] 0%, 95% CI -21 to 21) but did reduce case fatality (ARR 38%, 15 to 60). In a meta-analysis of patients in DECIMAL (DEcompressive Craniectomy In MALignant middle cerebral artery infarction), DESTINY (DEcompressive Surgery for the Treatment of malignant INfarction of the middle cerebral arterY), and HAMLET who were randomised within 48 h of stroke onset, surgical decompression reduced poor outcome (ARR 16%, -0.1 to 33) and case fatality (ARR 50%, 34 to 66). Surgical decompression reduces case fatality and poor outcome in patients with space-occupying infarctions who are treated within 48 h of stroke onset. There is no evidence that this operation improves functional outcome when it is delayed for up to 96 h after stroke onset

Mixed evidence exists regarding the role of cognitive reactivity (CR; cognitive responsivity to a negative mood) as a risk factor for recurrences of depression. One explanation for the mixed evidence may lie in the number of previous depressive episodes. Heightened CR may be especially relevant as a risk factor for the development of multiple depressive episodes and less so for a single depressive episode. In addition, it is theoretically plausible but not yet tested that the relationship between CR and number of episodes is moderated by the strength of automatic depression-related self-associations. To investigate (i) the strength of CR in remitted depressed individuals with a history of a single vs. multiple episodes, and (ii) the potentially moderating role of automatic negative self-associations in the relationship between the number of episodes and CR. Cross-sectional analysis of data obtained in a cohort study (Study 1) and during baseline assessments in two clinical trials (Study 2). Study 1 used data from the Netherlands Study of Depression and Anxiety (NESDA) and compared never-depressed participants (n=901) with remitted participants with either a single (n=336) or at least 2 previous episodes (n=273). Study 2 included only remitted participants with at least two previous episodes (n=273). The Leiden Index of Depression Sensitivity Revised (LEIDS-R) was used to index CR and an Implicit Association Test (IAT) to measure implicit self-associations. In Study 1, remitted depressed participants with multiple episodes had significantly higher CR than those with a single or no previous episode. The remitted individuals with multiple episodes of Study 2 had even higher CR scores than those of Study 1. Within the group of individuals with multiple episodes, CR was not heightened as a function of the number of episodes, even if individual differences in automatic negative self-associations were taken into account. The study employed a cross-sectional design, which

The aim of this study was to test the effect of intrapersonal and interpersonal emotional competence on cancer patients' supportive care needs, as mediated by anxiety and depression symptoms. Cross-sectional design: 137 cancer patients (42% breast or ovarian cancer, 58% gastrointestinal cancer) in 4 French hospitals completed the Profile of Emotional Competence (PEC), the Hospital Anxiety and Depression Scale (HADS), and the Supportive Care Needs Survey Short Form (SCNS-SF). Bootstrap methods with PROCESS Macro were used to test multiple mediation models. Emotional competence presented a direct or indirect beneficial effect on the satisfaction of supportive care needs, anxiety and depression symptoms. As expected, anxiety and depression symptoms had also strong positive correlations with unmet needs. All multiple mediation models were significant, except for physical needs: intrapersonal and interpersonal emotional competence impacted anxiety and depression symptoms, which in turn impacted psychological, sexual, care/support, and information needs. These innovative results show the important effect of patients' emotional competence on their supportive care need satisfaction, as mediated by anxiety and depression. Consequently, patients with high emotional competence may require less psychosocial input from medical clinicians. Thus, emotional competence may be integrated into health models and psychosocial interventions to improve patient adjustment. Further investigation is, however, needed to know which are the most beneficial specific emotional competences and at what point of the cancer pathway.

2008-05-01

The physiopathology of visual hallucinations in the hemianopic field secondary to occipital infarct is uncertain. We report the case of a patient with a history of occipital infarct who presented nonstereotyped complex hallucinations in the quadranopic field resulting from a second controlateral occipital infarct. Based on an experience with motion optical illusions, we suggested that the association of these two occipital lesions, involving the V5 motion area on the one side and the V1 area on the other side, could have produced the complex hallucinations due to a release phenomenon. The patient experienced simultaneously a double visual consciousness, with both hallucinations and real visual perceptions. The study of perceptual illusions in patients with visual hallucinations could illustrate the innovative theory of visual consciousness as being not unified but constituted of multiple microconsciousnesses.

The association between subjective cognitive fatigue and objective cognitive dysfunction in patients with multiple sclerosis (PwMS) has been studied, with conflicting results. To explore the impact of fatigue on cognitive function, while controlling for the influence of depression, disability, comorbidities, and psychotropic medications. PwMS completed a computerized cognitive testing battery with age- and education-adjusted cognitive domain scores. Disability (Expanded Disability Status Scale (EDSS)), cognitive fatigue, and depression were concurrently evaluated. In all, 699 PwMS were included. Both cognitive fatigue and depression were significantly and negatively correlated with the same cognitive domains: information processing speed, executive function, attention, motor function, and memory (-0.15 ⩽ r ⩽ -0.14 for cognitive fatigue; -0.24 ⩽ r ⩽ -0.19 for depression). Multivariate analysis revealed significant but small independent correlations only between depression and neuropsychological test results, while cognitive fatigue had no independent correlation with objective cognitive function except for a trend toward impaired motor function in highly fatigued PwMS. Depression and cognitive fatigue accounted for no more than 6% of the variance in objective cognitive domain scores. Cognitive fatigue is not independently related to objective cognitive impairment. Depression may influence cognitive function of PwMS primarily when it is severe. Cognitive impairment in PwMS should not be ascribed to fatigue or mild depression.

Acute myocardial infarction is the most dangerous complication of coronary atherothrombosis. There are several disparities in regard to its management around the world. The aim of this study is to analyze the specificities of management of acute myocardial infarction in Morocco. FES-AMI (Fès Acute Myocardial Infarction) is a prospective monocentric registry conducted in cardiology department of Hassan II university hospital in Fès. In this registry, we enrolled patients with acute myocardial infarction who presented within 5 days after symptom onset. From January 2005 to August 2015, we enrolled 1835 patients. Seventy-five percent of patients were males and mean age was 60 years old. Fifty-one percent of patients were smokers, 27% were hypertensives and 14% were diabetics. Sixty-six percent of patients had more than 2 risk factors. Time from symptom onset to hospital admission was less than six hours for 40% of the patients. Thirty-six percent of patients were admitted more than twelve hours after the onset of chest pain. Only 37% of patients received reperfusion therapy, 31% with in-hospital thrombolysis and 6% with primary angioplasty. In-hospital mortality was 7.6%. The patients enrolled in our registry have late presentation of acute myocardial infarction and less rate of reperfusion therapy. Furthermore, the majority of our patients have multiple risk factors and this result underlines the failure of preventive interventions. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

To evaluate the application of radionuclide infarct scintigraphy to diagnose myocardial infarction after revascularization, we obtained postoperative technetium 99m pyrophosphate myocardial scintigrams, serial electrocardiograms and CPK-MB isoenzymes in ten control and 51 revascularized patients. All control patients had negative electrocardiograms and scintigrams, but eight had positive isoenzymes. Eight revascularized patients had positive electrocardiograms, images and enzymes and two had positive scintigrams and enzymes with negative electrocardiograms. Thirty-four patients with negative electrocardiograms and scintigrams had positive isoenzymes; in only seven patients were all tests negative. Our data suggest radionuclide infarct scintigraphy is a useful adjunct to the electrocardiogram in diagnosing perioperative infarction. The frequent presence of CPK-MB in postoperative patients without other evidence of infarction suggests that further studies are required to identify all factors responsible for its release

Silent ischemia in patients after uncomplicated myocardial infarction

The purpose of this study was to determine the frequency and importance of silent ischemia in patients (pts) after the acute myocardial infarction (A MI) as well as to establish diagnostic and prognostic value of exercise stress test (EST), Holter (H) monitoring and thallium-201 (Tl) scintigraphy. All the three tests were performed 2-4 months following the AMI. The criterion for diagnosing myocardial ischemia on EST and H is 1 mm or more of horizontal or down-sloping ST depression. Additional criteria for Holter imply the ischemic episode should last one minute and be separated from other episodes by at least one minute. Planar thallium images were performed 5-10 minute after the stress test; the delayed images were obtained after 3-6 hours. Visual and quantitative methods were employed in the analysis of TI-scintigraphy. Scintigraphy was considered positive if exercise- induced perfusion defects showed redistribution. The study included 74 asymptomatic patients after the AMI. The patients were divided into two groups by results of quantitative Tl-scintigraphy: Group I - 44 pts with silent ischemia, Group II - 30 pts without ischemia. In Group I, out of 44 pts, 9 had a positive exercise stress, 4 showed a painless ST depression on Holter and 7 had both tests positive, whereas 24 pts had only scintigraphy positive. In Group II one patient had positive EST and H. Sensitivity and specificity were determined by results of coronary arteriography performed on 33 pts: EST (Se=40%, Sp=80%), H (Se=219, Sp=100%) and scintigraphy (Se=93%, Sp =80%). During the follow-up period lasting at least 12 months, in Group I 3 pts died, 1 developed a new myocardial infarction and 15 pts had painful ischemic occurrences. In Group II only 3 pts developed symptoms of angina pectoris. Tl-scintigraphy was the only non-invasive test showing significant correlation with the follow-up outcomes. The diagnostic and prognostic superiority of Tl-scintigraphy justifies its value as the initial

Both depression and smoking have been independently associated with lower heart rate variability (HRV), suggesting dysregulation of cardiac autonomic function. However, no studies have systematically explored the effects of smoking on HRV among depressed patients. This study examined differences in HRV based on smoking status among depressed individuals. Electrophysiological data were examined among 77 adult outpatients without a history of myocardial infarction, who met criteria for major depressive disorder or dysthymia. Frequency domain [low frequency (LF), high frequency (HF), LF/HF ratio, respiratory sinus arrhythmia (RSA)] parameters of HRV, and heart rate and inter-beat interval (IBI) data were compared between depressed smokers (n = 34) and depressed nonsmokers (n = 44). After controlling for covariates, depressed smokers, compared to depressed nonsmokers, displayed significantly lower LF, HF, and RSA. Among depressed patients, smoking is associated with significantly lower HRV, indicating dysregulated autonomic modulation of the heart.

Late contrast enhancement visualizes myocardial infarction, but the contrast to noise ratio (CNR) is low using conventional CT. The aim of this study was to determine if spectral CT can improve imaging of myocardial infarction. A canine model of myocardial infarction was produced in 8 animals (90-min occlusion, reperfusion). Later, imaging was performed after contrast injection using CT at 90 kVp/150 kVpSn. The following reconstructions were evaluated: Single energy 90 kVp, mixed, iodine map, multiple monoenergetic conventional and monoenergetic noise optimized reconstructions. Regions of interest were measured in infarct and remote regions to calculate contrast to noise ratio (CNR) and Bhattacharya distance (a metric of the differentiation between regions). Blinded assessment of image quality was performed. The same reconstruction methods were applied to CT scans of four patients with known infarcts. For animal studies, the highest CNR for infarct vs. myocardium was achieved in the lowest keV (40 keV) VMo images (CNR 4.42, IQR 3.64-5.53), which was superior to 90 kVp, mixed and iodine map (p = 0.008, p = 0.002, p energy in conjunction with noise-optimized monoenergetic post-processing improves CNR of myocardial infarct delineation by approximately 20-25%.

sup(99m)Tc-pyrophosphate (PYP) scintigraphy and 201 Tl myocardial scintigraphy were utilized for the diagnoses of the presence, the region, and the extent of myocardial infarction. Exercise 201 Tl myocardial scintigrams and exercise radionuclide ventriculography were utilized for diagnosis of coronary artery lesions in angina pectoris. Radionuclide ventriculography was used to investigate effects of coronary artery lesions on cardiac function and hemodynamics. In order to select adequate treatments for myocardial infarction and estimate the prognosis, it was necessary to detect the presence, the region, and the extent of acute myocardial infarction and to investigate effects of partial infarction on hemodynamics by using radionuclide imaging. Exercise myocardial scintigraphy could be carried out noninvasively and repeatedly for diagnosis of coronal artery disease. Therefore, this method could be applied widely. It was possible to use this method as a screening test of coronary artery diseases for the diagnoses of asymptomatic patients who showed ST changes in ECG, the patients with cardiac neurosis and the patency after a reconstructive surgery of coronary artery.

Traditional diagnoses of major depressive disorder (MDD) suggested that the presence or absence of stress prior to onset results in either 'reactive' or 'endogenous' subtypes of the disorder, respectively. Several lines of research suggest that the biological underpinnings of 'reactive' or 'endogenous' subtypes may also differ, resulting in differential response to treatment. We investigated this hypothesis by comparing the gene-expression profiles of three animal models of 'reactive' and 'endogenous' depression. We then translated these findings to clinical samples using a human post-mortem mRNA study. Affymetrix mouse whole-genome oligonucleotide arrays were used to measure gene expression from hippocampal tissues of 144 mice from the Genome-based Therapeutic Drugs for Depression (GENDEP) project. The study used four inbred mouse strains and two depressogenic 'stress' protocols (maternal separation and Unpredictable Chronic Mild Stress) to model 'reactive' depression. Stress-related mRNA differences in mouse were compared with a parallel mRNA study using Flinders Sensitive and Resistant rat lines as a model of 'endogenous' depression. Convergent genes differentially expressed across the animal studies were used to inform candidate gene selection in a human mRNA post-mortem case control study from the Stanley Brain Consortium. In the mouse 'reactive' model, the expression of 350 genes changed in response to early stresses and 370 in response to late stresses. A minimal genetic overlap (less than 8.8%) was detected in response to both stress protocols, but 30% of these genes (21) were also differentially regulated in the 'endogenous' rat study. This overlap is significantly greater than expected by chance. The VAMP-2 gene, differentially expressed across the rodent studies, was also significantly altered in the human study after correcting for multiple testing. Our results suggest that 'endogenous' and 'reactive' subtypes of depression are associated with largely

Thrombolysis due to acute ischemic stroke is associated with the risk of hemorrhagic infarction, especially after reperfusion. Recent experimental studies suggest that the main mechanism contributing to hemorrhagic infarction is oxidative stress caused by disruption of the blood-brain barrier. Edaravone, a free radical scavenger, decreases oxidative stress, thereby preventing hemorrhagic infarction during ischemia and reperfusion. In this study, we investigated the effects of edaravone on hemorrhagic infarction in a rat model of hemorrhagic transformation. We used a previously established hemorrhagic transformation model of rats with hyperglycemia. Hyperglycemia was induced by intraperitoneal injection of glucose to all rats (n  =  20). The rats with hyperglycemia showed a high incidence of hemorrhagic infarction. Middle cerebral artery occlusion (MCAO) for 1.5 hours followed by reperfusion for 24 hours was performed in edaravone-treated rats (n  =  10) and control rats (n  =  10). Upon completion of reperfusion, both groups were evaluated for infarct size and hemorrhage volume and the results obtained were compared. Edaravone significantly decreased infarct volume, with the average infarct volume in the edaravone-treated rats (227.6 mm(3)) being significantly lower than that in the control rats (264.0 mm(3)). Edaravone treatment also decreased the postischemic hemorrhage volumes (53.4 mm(3) in edaravone-treated rats vs 176.4 mm(3) in controls). In addition, the ratio of hemorrhage volume to infarct volume was lower in the edaravone-treated rats (23.5%) than in the untreated rats (63.2%). Edaravone attenuates cerebral infarction and hemorrhagic infarction in rats with hyperglycemia.

Full Text Available Despite therapeutic advances, acute myocardial infarction (AMI remains a leading cause of morbidity and mortality worldwide. One potential limitation of the current treatment paradigm is the lack of effective therapies to optimize reperfusion after ischemia and prevent reperfusion-mediated injury. Experimental studies indicate that this process accounts for up to 50% of the final infarct size, lending it importance as a potential target for cardioprotection. However, multiple therapeutic approaches have shown potential in pre-clinical and early phase trials but a paucity of clear clinical benefit when expanded to larger studies. Here we explore this history of trials and errors of the studies of cyclosporine A and other mitochondrial membrane permeability inhibitors, agents that appeared to have a promising pre-clinical record yet provided disappointing results in phase III clinical trials.

Multiple sclerosis (MS) is the chronic inflammatory and demyelinating disorder of central nervous system which is accompanied with disability and negative life style changes such as fatigue and depression. The aim of this study is to investigate the effect of coenzyme Q10 (CoQ10) supplementation on fatigue and depression in patients with MS. We performed a randomized, double-blinded, placebo-controlled trial to determine the effect of CoQ10 supplement (500 mg/day) vs. placebo for 12 weeks. Fatigue symptoms were quantified by means of fatigue severity scale (FSS) and the Beck depression inventory (BDI) was used to assess depressive symptoms. A significant decrease of FSS was observed in CoQ10 group during the intervention (P = 0.001) and significant increase of FSS change was observed within placebo group (P = 0.001). Repeated measure analysis of variance showed a significant time-by-treatment interaction for FSS (baseline 41.5 ± 15.6 vs. endpoint 45 ± 13.6; F1,45 = 55.23, P multiple sclerosis.

To assess the effect of early regional diastolic shape distortion or bulging of infarct zones due to infarct expansion on estimates of regional left ventricular dysfunction and infarct size by two-dimensional echocardiographic imaging. Quantitative two-dimensional echocardiograms from patients with a first Q wave myocardial infarction and creatine kinase infarct size data, and normal subjects, were subjected to detailed analysis of regional left ventricular dysfunction and shape distortion in short-axis images by established methods. Regional left ventricular asynergy (akinesis and dyskinesis) and shape distortion indices (eg, peak [Pk]/radius [ri]) were measured on endocardial diastolic outlines of short-axis images in 43 postinfarction patients (28 anterior and 15 inferior, 5.9 h after onset) and 11 normal subjects (controls). In the infarction group, endocardial surface area of asynergy was calculated by three-dimensional reconstruction of the images and infarct size from serial creatine kinase blood levels. Diastolic bulging of asynergic zones was found in all infarction patients. The regional shape distortion indices characterizing the area between the 'actual' bulging asynergic segment and the derived 'ideal' circular segment (excluding the bulge) on indexed sections were greater in infarct than control groups (Pk/ri 0.31 versus 0, P 0.001). Importantly, the degree of distortion correlated with overestimation of asynergy (r = 0.89, P < 0.001), and the relation between infarct size and total 'ideal' asynergy showed a leftward shift from that with 'actual' asynergy. Early regional diastolic bulging of the infarct zone results in overestimation of regional ventricular dysfunction, especially in patients with anterior infarction. This effect should be considered when assessing effects of therapy on infarct size, remodelling and dysfunction using tomographical imaging.

Obstructive sleep apnea (OSA) is an independent risk factor for many cardiovascular conditions such as coronary artery disease, myocardial infarction, systemic hypertension, pulmonary hypertension, and stroke. However, the association of OSA with outcomes in patients hospitalized for ST-elevation myocardial infarction remains controversial. We used the nation-wide inpatient sample between 2003 and 2011 to identify patients with a primary discharge diagnosis of ST-elevation myocardial infarction and then used the International Classification of Diseases, Clinical Modification code 327.23 to identify a group of patients with OSA. The primary outcome of interest was in-hospital mortality, and secondary outcomes were in-hospital cardiac arrest, length of stay and hospital charges. Our cohort included 1 850 625 patients with ST-elevation myocardial infarction, of which 1.3% (24 623) had documented OSA. OSA patients were younger and more likely to be male, smokers, and have chronic pulmonary disease, depression, hypertension, known history of coronary artery disease, dyslipidemia, obesity, and renal failure ( P ST-elevation myocardial infarction patients with recognized OSA had significantly decreased mortality compared with patients without OSA. Although patients with OSA had longer hospital stays and incurred greater hospital charges, there was no difference in incidence of in-hospital cardiac arrest. © 2017 The Authors.

The feasibility of acute infarct scintigraphy for the clinical evaluation of patients with known or suspected acute myocardial infarction is established. Further development of this methodologic approach may result in even better agents for the visualization of infarcts. Radiotracers with high affinity for the infarct, rapid blood clearance, and low concentrations in surrounding organs, such as liver and bone, would be more suitable than available radiopharmaceuticals for acute myocardial infarct scintigraphy. Ultimately, labeling these tracers and ultra-short-lived radionuclides will enable rapid sequential imaging to assess changes in the extent of infarction and to determine the efficacy of therapies aimed at limiting infarct size

Twenty-six neonatal infarcts were imaged with 0.6 T and 1.5-T magnets and correlated with US and/or CT. Periventricular leukomalacia (PVL) was seen in six cases: lobar infarction, ten cases; global infarction, six cases; and basal ganglia infarction, four cases. MR imaging was superior to US and CT in detecting hemorrhagic PVL and basal ganglia infarcts. MR demonstrates lobar infarcts better than US and CT because of a wider field of view, specificty, and improved gray and white matter differentiation. US underestimates the extent of brain destruction in global infarcts. These results indicate that MR is the single best imaging modality for detecting ischemic brain injury

Physical activity represents a promising treatment for major depressive disorder (MDD) in people with multiple sclerosis (MS). We conducted a single-blind, two-arm randomized controlled trial comparing a 12-week physical activity counseling intervention delivered primarily by telephone (n = 44) to a wait-list control group (N = 48). Ninety-two adults with MS and MDD or dysthymia (M(age) = 48 years; 86% female, 92% White) completed an in-person baseline assessment and were randomized to wait-list control or an intervention involving motivational-interviewing-based promotion of physical activity. The treatment group received an initial in-person session; 7 telephone counseling sessions (Weeks 1, 2, 3, 4, 6, 8, and 10), and an in-person session at Week 12. The primary outcome, treatment response, was defined as those with 50% or greater reduction in the Hamilton Depression Rating Scale (HAM-D) score. Our primary hypothesis, that the proportion of responders in the treatment group would be significantly greater than in the control group, was not confirmed. However, compared with the control group, those in the treatment group evidenced significantly lower depression severity on the HAM-D, on self-reported depression, and on a measure of potential side effects and at 12 weeks were less likely to meet the criteria for MDD as set forth in the Diagnostic and Statistical Manual of Mental Disorders (4th ed.). Physical activity increased significantly more in the treatment condition, though it did not mediate improvement in depression severity. Telephone-based physical activity promotion represents a promising approach to treating MDD in MS. Further research is warranted on ways to bolster the impact of the intervention and on mediators of the treatment effect.

To estimate the usefulness of the bedside swallowing assessment proposed by Smithard et al and neuroimaging findings characteristic for dysphagia, we studied the outcome of 102 patients with chronic cerebral infarction after assessment of swallowing by this test with brain computerized tomography (CT). All patients had a variety of motor disturbance and were admitted on a long-term medicare basis. They were divided into two groups according to the findings: the positive group (n=33), who showed any of the listed types of difficulty in swallowing water, and the negative group (n=69). Followed up to 2.2 years, their outcomes were studied. CT findings were studied on type of infarction, number and laterality of infarction, grade of periventricular lucency (PVL), presence of ventricular dilatation (VD), and severity of cortical atrophy (CA). The mean age was 76.4 years at registration and 61 were men. The frequency of severe dementia and disturbed ADL were significantly higher in the positive group. Eighteen patients died during the observation period and 15 of those were in the positive group, indicating higher, annual death rate (29.9% vs 2.2% in the negative group). All of the 15 patients in the positive group died of pneumonia. CT findings showed high incidence of multiple infarction, bilateral hemispheric lesion, severe PVL, VD, and severe CA in the positive group. These findings indicated that this evaluation method was useful in screening swallow function for patients with cerebral infarction in the chronic phase. Furthermore, CT findings suggested that severe white matter lesion, VD, and severe CA as well as multiple infarction seen in bilateral hemisphere was related to dysphagia, probably due to multiple factors involving pyramidal- and extrapyramidal-tracts with higher brain function.

Infarct extension, a process involving progressive extension of the infarct zone (IZ) into the normally perfused border zone (BZ), leads to continuous degradation of the myocardial function and adverse remodelling. Despite carrying a high risk of mortality, detailed understanding of the mechanisms leading to BZ hypoxia and infarct extension remains unexplored. In the present study, we developed a 3D truncated ellipsoidal left ventricular model incorporating realistic electromechanical properties and fibre orientation to examine the mechanical interaction among the remote, infarct and BZs in the presence of varying infarct transmural extent (TME). Localized highly abnormal systolic fibre stress was observed at the BZ, owing to the simultaneous presence of moderately increased stiffness and fibre strain at this region, caused by the mechanical tethering effect imposed by the overstretched IZ. Our simulations also demonstrated the greatest tethering effect and stress in BZ regions with fibre direction tangential to the BZ-remote zone boundary. This can be explained by the lower stiffness in the cross-fibre direction, which gave rise to a greater stretching of the IZ in this direction. The average fibre strain of the IZ, as well as the maximum stress in the sub-endocardial layer, increased steeply from 10% to 50% infarct TME, and slower thereafter. Based on our stress-strain loop analysis, we found impairment in the myocardial energy efficiency and elevated energy expenditure with increasing infarct TME, which we believe to place the BZ at further risk of hypoxia.

Silent ischemia in patients after the acute myocardial infarction

International Nuclear Information System (INIS)

Samarzija, M.

1991-01-01

The purpose of this study was to determine the frequency and importance of silent ischemia in patients (pts) after acute myocardial infarction (AMI) as well as to establish diagnostic and prognostic values of exercise stress test (EST), Holter (H) monitoring and thallium-201 (Tl) scintigraphy. All the tests were performed 2-4 months following the AMI. The criterion for diagnostic myocardial ischemia on EST and H is 1 mm or more of horizontal or down-sloping ST depression. Additional criteria for Holter imply that the ischemic episode should last one minute and be separated from other episodes by at least one minute. Planar thallium images were performed 5-10 minutes after the stress test; the delayed images were obtained after 3-6 hours. Visual and quantitative methods were employed in the analysis of Tl-scintigraphy. Scintigraphy was considered positive if exercise-induced perfusion defects showed redistribution. The study included 74 asymptomatic patients after the AMI. The patients were divided into two groups by results of quantitative Tl-scintigraphy: Group I - 44 pts with silent ischemia, Group II - 30 pts without ischemia. In Group I, out of 44 pts, 9 had a positive exercise stress test, 4 showed a painless ST depression on Holter and 7 had both tests positive, whereas 24 pts had only scintigraphy positive. In Group II one patient had positive EST and H. Sensitivity and specificity were determined by results of coronary arteriography performed on 33 pts: EST (Se=40%, Sp=80%), H (Se=21%, Sp=100%) and scintigraphy (Se=93%, Sp=80%). During the follow-up period lasting at least 12 months, in Group I 3 pts died, 1 developed a new myocardial infarction and 15 pts had painful ischemic occurrences. In Group II only 3 pts developed symptoms of angina pectoris. Tl-scintigraphy was the only non-invasive test showing significant correlation with the follow-up outcomes. The diagnostic and prognostic superiority of Tl-scintigraphy justifies its value as an initial

The evaluation of a febrile patient with acute abdominal pain represents a frequent yet possibly challenging situation in the emergency department (ED). Splenic infarction is an uncommon complication of infectious mononucleosis, and may have a wide range of clinical presentations, from dramatic to more subtle. Its pathogenesis is still incompletely understood, yet it may be associated with the occurrence of transient prothrombotic factors. We report the case of a 14-year-old boy who presented with fever, sore throat, left upper quadrant abdominal pain, and splenomegaly, with no history of recent trauma. Laboratory tests revealed a markedly prolonged activated partial thromboplastin time and positive lupus anticoagulant. Abdominal ultrasonography showed several hypoechoic areas in the spleen consistent with multiple infarctions. Magnetic resonance imaging eventually confirmed the diagnosis. He was admitted for observation and supportive treatment, and was discharged in good condition after 7 days. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous splenic infarction should be considered in the differential list of patients presenting with left upper quadrant abdominal pain and features of infectious mononucleosis; the diagnosis, however, may not be straightforward, as clinical presentation may also be subtle, and abdominal ultrasonography, which is often used as a first-line imaging modality in pediatric EDs, has low sensitivity in this scenario and may easily miss it. Furthermore, although treatment is mainly supportive, close observation for possible complications is necessary. Copyright © 2016 Elsevier Inc. All rights reserved.

Myocardial imaging using β-methyl-p-( 123 I)-iodophenylpentadecanoic acid (BMIPP) was performed in 11 patients with acute myocardial infarction. The left ventricular images were divided into 12 segments, and myocardial images with BMIPP were compared with coronary angiography (CAG), thallium-201 myocardial scintigraphy (Tl) and wall motion obtained by two-dimensional echocardiography (WM). When the culprit lesion was at the proximal point of the left anterior descending artery (LAD), all segments showed depressed uptake. In 3 cases with single vessel disease of the LAD, inferior wall of the basis showed reduced uptake of BMIPP despite the location of the culprit lesion. In cases with discordant uptake between the two tracers, BMIPP frequently showed more severely depressed uptake than Tl in the subacute phase, although the uptake of BMIPP correlated with that of Tl (τ=0.82, p<0.001). In such cases, the discordance was related to the improvement in WM from the acute phase to the convalescent phase. BMIPP uptake correlated with WM in the subacute phase (τ=0.50, p<0.001). BMIPP showed more severely depressed uptake while WM showed mild asynergy in most cases in which discordance was found between the BMIPP and WM findings. However, there was no correlation between the change in WM from the acute to subacute phases, or the uptakes of BMIPP and Tl alone. We concluded that the myocardial condition can be evaluated in detail in acute myocardial infarction by comparing the findings of BMIPP with those of Tl and WM. (author)

Ataxic hemiparesis (AH) is a classic lacunar syndrome associated with localized damage to the pons, internal capsule, thalamus, or corona radiata. A depression of metabolic activity known as crossed cerebellar diaschisis (CCD) is frequently observed in the cerebellar hemisphere contralateral to the site of the lesion in patients with AH. Though small cortical or subcortical lesions may result in AH, such occurrences are rare. The current report details the case of a patient with AH resulting from acute infarction associated with localized lesions of the postcentral gyrus who presented without CCD.

Post traumatic stress disorder is a psychiatric disease that is usually precipitated by life threatening stressors. Myocardial infarction, especially in the young can count as one such event. The development of post traumatic stress after a coronary event not only adversely effects psychiatric health, but leads to increased cardiovascular morbidity and mortality. There is increasing evidence that like major depression, post traumatic stress disorder is also a strong coronary risk factor. Early diagnosis and treatment of this disease in patients with acute manifestations of coronary artery disease can improve patient outcomes.

Full Text Available Cytomegalovirus (CMV is a type of herpes infection that has a characteristic feature of maintaining lifelong latency within the host cell. CMV manifestations can cover a broad spectrum from fever to as severe as pancytopenia, hepatitis, retinitis, meningoencephalitis, Guillain-Barre syndrome, pneumonia, and thrombosis. Multiple case reports of thrombosis associated with CMV have been reported. Deep vein thrombosis or pulmonary embolism is more common in immunocompetent patients while splenic infarct is more common in immunocompromised patients. However, here we report a female patient on low-dose methotrexate for rheumatoid arthritis who presented with both pulmonary embolism and splenic infarct.

Full Text Available Abstract Background People with multiple sclerosis (MS are at high risk of depression. We undertook a pilot trial of computerised cognitive behavioural therapy (CCBT for the treatment of depression in people with MS to test the feasibility of undertaking a full trial. Methods Participants with a diagnosis of MS and clinical levels of depression were recruited through out-patient clinics and postal screening questionnaires at two UK centres and randomised to CCBT or usual care. Clinical outcomes included the Beck Depression Inventory (BDI-II and Multiple Sclerosis Impact Scale (MSIS-29 at baseline, 8 and 21 weeks. Feasibility outcomes included: recruitment rate; reasons for refusal, withdrawal and dropout; feasibility and acceptability of the proposed outcome measures; sample size estimation and variation in and preferences for service delivery. Results Twenty-four participants were recruited. The recruitment rate, calculated as the proportion of those invited to fill in a screening questionnaire who were consented into the trial, was 4.1%. Recruitment through out-patient clinics was somewhat slower than through screening questionnaire mail-out but the overall recruitment yield was similar. Of the 12 patients in the CCBT arm, 9 (75% completed at least four, and 6 completed all 8 CCBT sessions. For completers, the median time (IQR to complete all eight CCBT sessions was 15 (13 to 20 weeks. Participants expressed concern about the face validity of the Beck Depression Inventory II for the measurement of self-reported depression in people with MS. The MSIS-29 was the patient-reported outcome measure which participants felt best reflected their concerns. The estimated sample size for a full trial is between 180 and 390 participants. NHS partners were not delivering CCBT in community facilities and participants preferred to access CCBT at home, with no one expressing a preference for use of CCBT in an alternative location. Conclusions A definitive

Changes of serum myosin light chain I (Myosin LCI) concentrations and creatine kinase (CK) activities were serially measured in 23 patients with acute myocardial infarction. Intracoronary thrombolysis was performed in 14 patients (ICT group) while the remaining 9 patients were treated in the conventional manner (non ICT group). The relationships between the maximum levels of serum Myosin LCI or CK and a myocardial infarct size index or left ventricular function were evaluated in 18 patients. The myocardial infarct size index was determined by 201 Tl myocardial scintigrams performed in the chronic phase. Multiple peaks of Myosin LCI were observed in 64% (9/14) of the ICT group and the first peak in 6 of these patients appeared much earlier in the same time as CK peak than in the non-ICT group, while multiple peaks were seen only in one case in the non-ICT group. The infarct size index by 201 Tl myocardial SPECT correlated with maximum Myosin LCI levels (r=0.88, p<0.001, n=10) and CK activities (r=0.67, p<0.05, n=10). These results indicate that the measurement of serum Myosin LCI is very useful for estimating the extent of myocardial damage and suggest that myocardial degeneration occurs at a very early phase of myocardial infarction.

To explain the clinical significance of stress(st)-induced ST-segment (ST) changes postinfarction, 93 patients with previous myocardial infarction (MI) were performed st- 201 Tl myocardial single photon emission computed tomography (SPECT) and compared ST changes with SPECT, coronary arteriographic and left ventriculographic findings. 30 out of 93 cases (32%) had ST depression, 20 (21.5%) had ST elevation, 9 (10%) had both ST depression and elevation and remaining 34 (36.5 %) had no significant ST changes. In single vessel disease, ST depression were noted in 29% (12/42), while in multivessel disease, 53% (27/51). 35 out of 39 cases (90%) with ST depression had transient perfusion defect but no apparent relation was noted between location of ST depression on ECG and region of transient perfusion defect in SPECT. All of 28 cases with ST elevation were noted in anterior MI cases, and 26 out of these showed severe LV wall motion abnormality in contrast left ventriculography and broad anterior permanent defect in SPECT. Only 15 cases (54%) showed slight redistribution. Thus, we conclude that in patients with previous MI, st-induced ST depression seems to reflect myocardial ischemia and ST elevation possibly related abnormal LV wall motion. (author)

A 53-year-old male suffered splenic infarction etiologically related to atrial fibrillation and non-obstructive hypertrophic cardiomyopathy. The main clinical manifestations were a one-month history of epigastric and left upper quadrant pain, with tenderness to palpation in the later zone. Laboratory tests revealed a slight leucocytosis (14.700) with left shift and a marked increase in LDH concentration (945 IU). Abdominal CAT and arteriography established the diagnosis, Echography proved normal. Patient evolution was satisfactory with conservative medical treatment. We conclude that splenic infarction should be considered in all cases of acute or chronic pain in the left hypochondrium. The diagnosis is established by CAT, arteriography and hepatosplenic gammagraphy. Medical management is initially advocated, surgery being reserved for those cases involving complications or in which diagnosis is not clear. Emphasis is placed on the main etiological, clinical, diagnostic and management characteristics of splenic infarction.

Background The association of particulate matter (PM) with cardiovascular morbidity and mortality is well documented. PM-induced ischemia is considered a potential mechanism linking PM to adverse cardiovascular outcomes. Methods and Results In a repeated-measures study including 5,979 observations on 48 patients aged 43–75 years, we investigated associations of ambient pollution with ST-segment level changes averaged over half-hour periods, measured in the modified V5 position by 24-hr Holter electrocardiogram monitoring. Each patient was observed up to 4 times within one year after a percutaneous intervention for myocardial infarction, acute coronary syndrome without infarction, or stable coronary artery disease without acute coronary syndrome. Elevation in fine particles (PM2.5) and black carbon (BC) levels predicted depression of half-hour averaged ST-segment levels. An interquartile increase in the previous 24-h mean BC level was associated with a 1.50-fold increased in risk of ST-segment depression ≥0.1 mm (95% CI: 1.19, 1.89) and a −0.031 mm (95% CI: −0.042, −0.019) decrease in half-hour averaged ST-segment level (continuous outcome). Effects were greatest within the first month after hospitalization, and for patients with myocardial infarction during hospitalization or with diabetes. Conclusions ST-segment depression is associated with increased exposure to PM2.5 and BC in cardiac patients. The risk of pollution-associated ST-segment depression may be greatest in those with myocardial injury in the first month after the cardiac event. PMID:18779445

2014-01-01

Highlights: • A plethora of pulmonary and systemic disorders, often associated with grave outcomes, may cause pulmonary infarction. • A stereotypical infarct is a peripheral wedge shaped pleurally based opacity but imaging findings can be highly variable. • Multimodality imaging is key to diagnosing the presence, aetiology and complications of pulmonary infarction. • Multimodality imaging of pulmonary infarction together with any ancillary features often guide to early targeted treatment. • CT remains the principal imaging modality with MRI increasingly used alongside nuclear medicine studies and ultrasound. - Abstract: The impact of absent pulmonary arterial and venous flow on the pulmonary parenchyma depends on a host of factors. These include location of the occlusive insult, the speed at which the occlusion develops and the ability of the normal dual arterial supply to compensate through increased bronchial arterial flow. Pulmonary infarction occurs when oxygenation is cut off secondary to sudden occlusion with lack of recruitment of the dual supply arterial system. Thromboembolic disease is the commonest cause of such an insult but a whole range of disease processes intrinsic and extrinsic to the pulmonary arterial and venous lumen may also result in infarcts. Recognition of the presence of infarction can be challenging as imaging manifestations often differ from the classically described wedge shaped defect and a number of weighty causes need consideration. This review highlights aetiologies and imaging appearances of pulmonary infarction, utilising cases to illustrate the essential role of a multimodality imaging approach in order to arrive at the appropriate diagnosis

In 120 cases of patients with cerebral infarction, the affected areas in the CT images were analyzed with special reference to the site, the size, and the extension. Moreover, on 39 scans of 34 cases examined with 8 weeks after the onset of strokes, the CT images were analyzed from the viewpoint of the presence of a mass effect, edema, contrast enhancement, and the accompanying hemorrhage. From these investigations, the authors have obtained the following results; 1) The greatest incidence of infarcts was in the area supplied by the middle cerebral artery (57% of the cases), and, among those, the area of the lenticulostriate arteries showed the highest incidence (53%). Even in the posterior fossa, infarcts were found in 6% of the cases. These findings are coincident with those in autopsied cases. 2) Putaminal infarcts and infarctions occurring in the area supplied by the calcarine artery seemed to be uniformity of the arcuate pattern. 3) Most of the infarcts in the perfusion area of the anterior cerebral artery and the basal ganglia were found to be small and multifocal; they were thought to correspond with water-shed and/or lacunar infarcts. 4) In approximately 25% of the cases examined within 8 weeks after the onset of strokes, the CT images revealed mass effects which had never been observed after more than 3 weeks. In conclusion, the presence of a mass effect, accompanying hemorrhage, and contrast enhancement detected by CT should lead us to reconsider the conventional management of cerebral infarction.

In order to examine the accuracy of ECG gated cardiac CT (G-CCT), G-CCT findings were compared with ECG and cardiac echographic findings in 25 cases of old myocardial infarction. From the detection rate according to the infarct area, abnormal findings in the anterior wall and the septum obtained from G-CCT were in good accordance with those from ECG. Although all of the G-CCT findings did not agree with those of cardiac echography in cases in which abnormal findings were seen in multiple areas, the detection rate of cardiac abnormal findings as a whole by G-CCT was the same as that by cardiac echography.

There were few studies on the spectral analysis of multiple-lead epicardial electrograms in chronic myocardial infarction. Spectral analysis of multi-lead epicardial electrograms was performed in 6 sham-operated dogs (N group) and 8 dogs with 4-week-old myocardial infarction (MI group). Four weeks after the ligation of left anterior descending coronary artery, fast Fourier transform was performed on 60-lead epicardial electrograms, and then inverse transform was performed on 5 frequency ranges from 0 to 250 Hz. From the QRS onset to QRS offset, the time integration of unsigned value of reconstructed waveform was calculated and displayed as AQRS maps. On 0-25 Hz AQRS map, there was no significant difference between the 2 groups. In the frequency ranges of 25-250 Hz, MI group had significantly smaller AQRS values than N group solely in the infarct zone. It was shown that high frequency potentials (25-250 Hz) within QRS complex were reduced in the infarct zone.

Objective: To construct the acute myocardial infarction models in rats with blood stasis and study the difference on blood biochemics between the acute myocardial infarction models with blood stasis and the simple acute myocardial infarction models. Methods: Wistar rats were randomly divided into control group, acute blood stasis model group, acute myocardial infarction sham operation group, acute myocardial infarction model group and of acute myocardial infarction model with blood stasis group. The acute myocardial infarction models under the status of the acute blood stasis in rats were set up. The serum malondialdehyde (MDA), nitric oxide (NO), free fatty acid (FFA), tumor necrosis factor-α (TNF-α) levels were detected, the activities of serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and the levels of prostacycline (PGI2), thromboxane A 2 (TXA 2 ) and endothelin (ET) in plasma were determined. Results: There were not obvious differences in MDA, SOD, GSH-Px and FFA between the acute myocardial infarction models with blood stasis in rats and the simple acute myocardial infarction models (P 2 and NO, and the increase extents of TXA 2 , ET and TNF-α in the acute myocardial infarction models in rats with blood stasis were higher than those in the simple acute myocardial infarction models (P 2 and NO, are significant when the acute myocardial infarction models in rats with blood stasis and the simple acute myocardial infarction models are compared. The results show that it is defective to evaluate pharmacodynamics of traditional Chinese drug with only simple acute myocardial infarction models. (authors)

To identify high-risk subgroups of inferior myocardial infarction, 75 patients presenting with their first inferior infarction were investigated by sequential gated blood pool scans. The patients were divided into four groups based on the right ventricular function (RVF) and anterior wall motion (AWM) of the left ventricle by scan at the time of admission. A second blood pool scan was performed at ten days to evaluate RV and LV function. Thirty-eight patients had cardiac catheterization before discharge and all patients were followed up for one year to determine their clinical outcome. Depressed RVF and reduced AWM were observed in 26 (35%) (Group A); depressed RVF and normal AWM were found in 20 (27%) (Group B); reduced AWM and normal RVE in 10 (13%) (Group C); and normal RVF and AWM in 19 (25%) (Group D). The mean values of biventricular function (LVEF, RVEF) in groups A, B, C, and D were (44.9 +- 8.4%, 32.5 +- 9.9%), (59.9 +- 8.6%, 34.5 +- 8.0%), (44.9 +- 15.7%, 48.2 +- 3.3%), and (60.4 +- 9.1%, 51.6 +- 10.6%), respectively, at admission. In serial measurements, LVEF did not change significantly in any group, however, RVEF improved nearly 10 points in groups A and B at 10 days. Group A also had the highest incidence (82 %) of left anterior descending coronary artery involvement, and the highest mean creatine phosphokinase levels (762 +- 318 U/1): Furthermore, group A had a high incidence of major complications during their hospital course and high mortality during the one-year follow-up. These data clearly identified group A as a high-risk subgroup of patients with inferior infarction.

To determine the role of MR contrast enhancement in evaluating time course of brainstem infarction. MR imaging with IV administration of gadopentetate dimeglumine was retrospectively reviewed in 43 patients with clinically and radiologically documented brainstem infarctions. The pattern of infarction was classified into spotty and patchy. Presence of parenchymal enhancement in infarction was evaluated. By location, there were 34 pontine, 3 midbrain, 6 medullary infarctions. The age of the infarctions ranged from 1 day to 9 months, with 5 patients scanned within 3 days and 10 scanned within 2 weeks of clinical ictus. Abnormalities on T2-weighted images were encountered in every case, with spotty pattern in 14 cases and patchy pattern in 29 cases. Parenchymal contrast enhancement was seen in 9 cases(20%), primarily occurring between days 8 and 20. MR contrast enhancement in brainstem infarction was infrequent that it may not be useful in the estimation of the age of infarction.

To determine whether there were incremental mental health impacts, specifically on depression trajectories, as a result of the 2008 economic crisis (the Great Recession) and subsequent Hurricane Sandy. Using latent growth mixture modeling and the ORANJ BOWL dataset, we examined prospective trajectories of depression among older adults (mean age, 60.67; SD, 6.86) who were exposed to the 2 events. We also collected community economic and criminal justice data to examine their impact upon depression trajectories. Participants (N=1172) were assessed at 3 times for affect, successful aging, and symptoms of depression. We additionally assessed posttraumatic stress disorder (PTSD) symptomology after Hurricane Sandy. We identified 3 prospective trajectories of depression. The majority (83.6%) had no significant change in depression from before to after these events (resilience), while 7.2% of the sample increased in depression incrementally after each event (incremental depression). A third group (9.2%) went from high to low depression symptomology following the 2 events (depressive-improving). Only those in the incremental depression group had significant PTSD symptoms following Hurricane Sandy. We identified a small group of individuals for whom the experience of multiple stressful events had an incremental negative effect on mental health outcomes. These results highlight the importance of understanding the perseveration of depression symptomology from one event to another. (Disaster Med Public Health Preparedness. 2018;page 1 of 10).

Full Text Available  Objectives: To determine the incidence of early left ventricular infarct expansion within five days after first anterior ST-segment elevation myocardial infarction and the effect of early thrombolytic therapy on the incidence of early infarct expansion compared with late thrombolytic therapy.Methods: In a prospective study of 101 patients (75males and 26 females, with the first attack of acute anterior myocardial infarction, their ages ranged from 40-80 years (mean age: 61.07±10.78 who had been admitted to the Coronary Care Unit of Hawler Teaching Hospital for the period from July 2007 through to September 2009. Those who received alteplase ≤3 hours of acute myocardial infarction were labelled as group-I (49 patients and those who received alteplase >3-12 hours were labelled as group-II (52 patients.Results: The incidence of early left ventricular infarct expansion was diagnosed by 2D-echocardiography and was found to be 17.8�20Group I patients had a lower incidence of early left ventricular infarct expansion (8.16�20compared with group-II (26.92�20 p=0.014. Patients with early left ventricular infarct expansion had a higher frequency rate of left ventricular systolic dysfunction (94.44�20compared to patients without early left ventricular infarct expansion (8.43�20p<0.001. There was a significant difference in the incidence of in-hospital mortality between the patients who developed early left ventricular infarct expansion (11.1�20compared with patients without early left ventricular infarct expansion (1.2�20p=0.025.Conclusion: Early reperfusion therapy in acute anterior myocardial infarction can decrease the incidence of early left ventricular infarct expansion, preserve left ventricular systolic function and decrease in-hospital mortality.

1994-01-01

To evaluate the correlation between onset of brain infarction and Gd-DTPA enhancing patterns on MRI. We reviewed MRI of 58 lesions in 45 patients with clinically documented brain infarction retrospectively. Axial, coronal and sagittal T1WI (TR/TE 450-520/20), T2WI (TR/TE 2190/90) and Gd-DTPA enhanced T1WI were performed with a 0.5T superconductive MR system. We analyzed Gd-enhancing patterns that were divided into intravascular, meningeal, and parenchymal enhancement. Parenchymal pattern was subdivided into mottled, partial ring like and dense enhancement. Intravascular enhancement was seen at 1-10 days in 30(53%) of 58 infarctions. Meningeal enhancement (13%) was noted at 1-6 days. Parenchymal enhancement (50%) was seen at 2-28 days and subdividing patterns are as follows: The mottled enhancement pattern was seen earlier at 2-8 days and partial ring like or dense enhancement patterns at 5-28 days. After reviewing Gd-enhanced MRI of infarction, the intravascular and meningeal enhancement patterns were earlier than parenchymal enhancement. Among parenchymal patterns, the mottled pattern was seen earlier than partial ring like or dense patterns. In conclusion, Gd-enhancing patterns of brain infarction are useful in estimating the age of infarction including acute infarction

Fluctuating drowsiness following cardiac catheterisation: artery of Percheron ischaemic stroke causing bilateral thalamic infarcts.

An 81-year-old man underwent cardiac catheterisation to investigate breathlessness and left ventricular impairment of unknown cause. He had unobstructed coronary arteries. Immediately following the procedure, he became suddenly unresponsive with vertical gaze palsy, anisocoria and bilateral upgoing plantar responses. He made a rapid recovery to his premorbid state 25 min later with no residual focal neurological signs. He then had multiple unresponsive episodes, interspaced with complete resolution of symptoms and neurological signs. MRI of the brain identified bilateral medial thalamic infarcts and midbrain infarcts, consistent with an artery of Percheron territory infarction. By the time the diagnosis was reached, the thrombolysis window had elapsed. The unresponsive episodes diminished with time and the patient was discharged to inpatient rehabilitation. At 6-month review after the episode, the patient has a degree of progressive cognitive impairment. 2017 BMJ Publishing Group Ltd.

Jugdutt, B.I.; Hutchins, G.M.; Bulkley, B.H.; Becker, L.C.

1979-01-01

Myocardial infarcts were examined in dogs to determine the spatial distribution of infarction in the region at risk and the relation between infarction and collateral blood flow. Permanent occlusion of the left circumflex (LC) coronary artery at a constant site was made in 27 conscious dogs that were sacrificed 2 days later. The anatomic region at risk was defined by postmortem coronary arteriography as the volume of the occluded LC coronary bed. The masses of the left ventricle (LV), infarct (I) and risk region (R) were calculated from planimetered areas of weighted bread-loaf sections of LV. Infarct size was directly related to the mass of the risk region (I = 0.53 R - 9.87; r = 0.97; p < 0.001). There was no infarction when R was less than about 20 g or 20% of the LV. The infarcts were mainly subendocardial and tapered from base to apex of the LV; 34% of the risk region became infarcted at the base compared with 22% at the apex. In all dogs, a significant rim of noninfarcted myocardium was identified at lateral aspects of the risk region, even at the endocardial surface. Using 9-μ radioactive microspheres, initial postocclusion flow at the margin of the infarct, but well within the risk region, was higher than at the center, and outer flows were higher than inner flows. Postocclusion flow was even higher in the noninfarcted rim within the risk region, but was still significantly less than flow to normal, nonrisk areas. Collateral flows throughout the risk region increased during the first hour after occlusion, and were even higher at 2 days.Epicardially and laterally within the anatomic risk region there is a substantial amount of tissue that does not infarct despite initally reduced blood flow

Primary care physicians have a vital role to play in identifying depression in their elderly patients. Diagnosis may be difficult, because symptoms are atypical and frequently include psychomotor agitation, somatic symptoms, and complaints of memory loss. Patients with medical illnesses, such as cancer, postmyocardial infarction, stroke, Parkinson's disease, and early Alzheimer's disease are particularly vulnerable to depression. Drugs that may cause depressive symptoms are digitalis at toxic levels, beta-blockers, centrally acting antihypertensives, immunosuppressants, and nonsteroidal anti-inflammatory agents. Cyclic antidepressants are the drugs of first choice. Selection depends on the patient's physical health and current medications and the side effect profile of the drug. Side effects are more pronounced in old age because of drug accumulation owing to slowed clearance. Troublesome side effects are anticholinergic effects, orthostatic hypotension, sedation, cardiotoxicity, and weight gain. The most useful antidepressants for geriatric patients are the secondary amines, desipramine and nortriptyline. The second-generation drug trazodone has the advantage of causing the least anticholinergic effects, but it is very sedating. Before treatment, the patient should have an electrocardiogram, liver function tests, tonometry, sitting and standing blood pressures, evaluation of urinary symptoms for outflow obstruction, review of current medications, and estimation of suicide risk. Cyclic antidepressants are contraindicated during recovery from myocardial infarction, in heart disease when there is severe impairment of myocardial performance, in seizure disorders, and in the presence of glaucoma or a large prostate. Drug interactions that may cause trouble can occur with epinephrine, MAO inhibitors, thyroid hormone, cimetidine, and centrally acting antihypertensives. Dosage should start low, increasing usually by 25 mg every 4 to 5 days until a therapeutic level is

Full Text Available Aim. To study the reasons of low adherence to treatment in patients after myocardial infarction as well as methods of its correction considering the mental and emotional state of patients. Material and methods. Patients (n=115 after myocardial infarction registered in "Acute Myocardial Infarction Register» were enrolled into the study. The Moriscos-Green scale was used to determine the degree of adherence to treatment, and psycho-emotional state of patients was assessed by the Hospital Anxiety and Depression Scale (HADS. The special questionnaire was used to study the causes of poor adherence. Results. Only 45% of patients after myocardial infarction have a high commitment to the doctor's recommendations. The main reason for low adherence was forgetfulness (42%. Among other reasons were: fear of side effects (16%; lack of therapeutic effect according to patients' opinion (12%; doubts about the doctor's prescriptions (14%; a large number of prescribed drugs (12%; high cost of drugs (4%. The structure of the causes of poor adherence to treatment varied greatly depending on the psycho-emotional status. Adherence to treatment can be improved by specific physician’s actions (48.5% of patients. At the same time 14% of patients did not want to take drugs for a long time under any circumstances. Conclusion. Adherence to treatment of patients after myocardial infarction deserves attention from doctors. The personalized approach considering patient’s opinion, as well as their specific features, is essential for the development of ways to improve adherence.

We present a case of left striatocapsular infarction manifest clinically as a transient right hemiparesis. MRI showed a left striatocapsular infarct. Striatocapsular infarction, unlike lacunar infarction, is often associated with occlusive disease of the carotid artery. In order to screen the carotid vessels, cervical MR angiography (MRA) was performed during the same examination, demonstrating a left internal carotid artery occlusion, confirmed by contrast arteriography. MRA, a noninvasive modality, can be a useful adjunct to MRI, when diagnostic information concerning the cervical carotid artery is needed. (orig.)

Mood disorders, as defined by the World Mental Health and the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, have a 12-month prevalence which varies from 3% in Japan to over 9% in the US. A recent American survey found the prevalence of current depression to be 9% and the rate of current major depression to be 3.4%. All studies of depressive disorders have stressed the importance of the mortality and morbidity associated with depression. The mortality risk for suicide in depressed patients is more than 20-fold greater than in the general population. Recent studies have also shown the importance of depression as a risk factor for cardiovascular death. The risk of cardiac mortality after an initial myocardial infarction is greater in patients with depression and related to the severity of the depressive episode. Greater severity of depressive symptoms has been found to be associated with significantly higher risk of all-cause mortality including cardiovascular death and stroke. In addition to mortality, functional impairment and disability associated with depression have been consistently reported. Depression increases the risk of decreased workplace productivity and absenteeism resulting in lowered income or unemployment. Absenteeism and presenteeism (being physically present at work but functioning suboptimally have been estimated to result in a loss of $36.6 billion per year in the US. Worldwide projections by the World Health Organization for the year 2030 identify unipolar major depression as the leading cause of disease burden

Studies of depression and anxiety in multiple sclerosis (MS) patients have reported higher rates in MS patients than the general population. To estimate the risk of depression and anxiety and the use of tricyclic antidepressant and selective serotonin reuptake inhibitors (SSRI) prescriptions, in the pre-diagnostic and the post-diagnostic period of MS compared to the background population. A cohort of 5084 MS patients was included and matched with a control population of 24,771 persons linked to nationwide registers. Logistic regression analyses were performed estimating odds ratios (OR). In the pre-diagnostic period, the OR for having a diagnosis of depression and anxiety is 1.4 (95% confidence interval (CI) =1.05-1.88), and the OR of redemption prescriptions of TCAs is 1.90 (CI=1.54-2.34) and OR is 1.34 (CI= 1.20-1.51) for SSRI. In the post-diagnostic period the OR is 1.23 (CI= 0.92-1.64) for depression and anxiety diagnosis. The OR is 6.70 (CI=5.81-7.72) for TCA and OR is 2.46 (CI= 2.25-2.69) for SSRI. During both the pre- diagnostic and post-diagnostic period, MS patient have increased risk of depression and anxiety diagnoses and redemption of antidepressant and anxiolytic prescriptions, compared to the background population. © The Author(s), 2015.

Ninety-one patients with chest pain suggestive of acute myocardial infarction were studied by static technetium /sup 99m/Tc stannous pyrophosphate scintigraphy and dynamic sodium pertechnetate /sup 99m/Tc cardioangiography. Twenty-three of 26 patients (88%) with acute transmural infarcts and 12 of 17 patients (71%) with nontransmural infarcts had abnormal static studies. In 45 patients with negative scintigrams, ECG or serum enzyme changes consistent with acute infarction failed to develop. Three false-positive static studies (6%) were recorded. Twenty of 43 (47%) patients with acute infarction had hemodynamic or structural abnormalities identified by cardioangiography. The dynamic study also proved helpful in localizing the site of infarction and in ruling out certain causes of false-positive static scintigrams

Mexico has been positioned as the country with the highest mortality attributed to myocardial infarction among the members of the Organization for Economic Cooperation and Development. This rate responds to multiple factors, including a low rate of reperfusion therapy and the absence of a coordinated system of care. Primary angioplasty is the reperfusion method recommended by the guidelines, but requires multiple conditions that are not reached at all times. Early pharmacological reperfusion of the culprit coronary artery and early coronary angiography (pharmacoinvasive strategy) can be the solution to the logistical problem that primary angioplasty rises. Several studies have demonstrated pharmacoinvasive strategy as effective and safe as primary angioplasty ST-elevation myocardial infarction, which is postulated as the choice to follow in communities where access to PPCI is limited. The Mexico City Government together with the National Institute of Cardiology have developed a pharmaco-invasive reperfusion treatment program to ensure effective and timely reperfusion in STEMI. The model comprises a network of care at all three levels of health, including a system for early pharmacological reperfusion in primary care centers, a digital telemedicine system, an inter-hospital transport network to ensure primary angioplasty or early percutaneous coronary intervention after fibrinolysis and a training program with certification of the health care personal. This program intends to reduce morbidity and mortality associated with myocardial infarction. Copyright © 2016 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A.

We describe a case of diabetic muscle infarction which had atypical features of hyperintensity of the affected muscle on T1-weighted images. Biopsy was performed which revealed diffuse extensive hemorrhage within the infarcted muscle. We believe increased signal intensity on T1-weighted images should suggest hemorrhage within the infarcted muscle. (orig.)

[The relationship between depression, anxiety and heart disease - a psychosomatic challenge].

Depressive and cardiological disorders present a major comorbidity. Their manifold interrelations may be best analysed within a biopsychosocial model of disease. A systematic research was done on empirical studies published during the last 15 years and dealing with epidemiological, etiopathogenetic and therapeutic dimensions of the comorbidity of depression, anxiety and heart disease. From an epidemiological perspective recurrent depressions are associated with a significantly increased risk of coronary heart disease. Depressive disorders play a major role in triggering critical cardiac events, e.g. myocardial infarction. The prevalence rates of depressive disorders in various cardiological conditions are significantly higher than the frequencies that can be expected in healthy general population. Depression shows a negative impact on the somatic morbidity and mortality during the further course of illness. Anxiety and posttraumatic stress disorders seem to be interrelated with cardiological conditions in quite a similar way, probably contributing even more negatively to critical and lethal cardiological events than depression. From an etiopathogenetic perspective some clusters of depressive symptoms seem to be linked to cardiotoxicity more closely than other, vital exhaustion, anhedonia, and hopelessness probably mediating a special risk. In any case, postmyocardial infarct depression that proves treatment-resistent indicates a negative prognosis of the prevailing cardiological condition. On a level of psychological and psychosocial constructs type-A personality, anger/hostility, type-D personality, and alexithymia have been explored regarding its proper pathogenetic role. Psychological and psychopathological variables have to be set into a context of psychosocial stressors on the one hand, and have to be simultaneously analysed with various underlying psycho- and neurobiological variables on the other. Above all, HPA- and sympathicomedullary dysfunctions, reduced

Full Text Available Aspirin and clopidogrel are usually used individually to prevent adverse cardiovascular events and stroke. They are used in stabilizing the blood pressure in patients of myocardial infarction while combination therapy of aspirin and Clopidogrel (dual anti-platelet therapy is used for preventing adverse cardiovascular events in myocardial infarction patients. A cross-sectional observational study is conducted through a structured questionnaire from 110 patients of K.I.H.D (Karachi Institute of Heart Disease hospital, Karachi, Pakistan. Indoor/admitted patients with diagnosis of acute coronary syndrome (ACS, non-ST elevation myocardial infarction (NSTE-MI, ST elevation myocardial infarction (STE-MI, supra ventricular tachycardia (SVT were included along with those with previous or current onset of angina pectoris or heart attack. Information from the test reports of these patients was included in the data. Patients without proper test reports were excluded from the study. Combination therapy duration is considered as key tool for evaluation. Out of 100 patients (after exclusion criteria applied almost 18% patients were using the combination therapy for 10 to 25 years while 52% of patients were using the combination therapy for 1 to 10 years. Platelet count of 88% patients was found to be in between 1,50,000–3,50,000/µl. Remaining patients had less than 1,50,000 µl to more than 3,50,000 to 4,50,000 µl. Most frequently reported side effects were chest pain, respiratory issues, headache and depression. On the basis of our data analysis it is concluded that long duration dual anti-platelet therapy will not harm platelet count in human blood but it can create drug dependency in patients. Hypertension is not completely cured with this therapy but can help in stabilizing blood pressure.

Objective: to investigate the risk factors of short-term poor outcome among patients suffering from acute cerebral infarction who had different subtypes of cerebral infarction. Methods: A total of 3231 acute cerebral infarction patients were included in the present study. Data on demographic characteristics, life style, risk factors, history of cardiovascular disease, admission blood pressure, and clinical outcome at discharge were collected for all participants. Poor outcome was defined as NIHSS ≥10 at discharge or death occurring during hospitalization. The association between poor outcome of cerebral infarction and risk factors was analyzed by using multiple logistic models. Results: Incidence rate of poor outcome is the highest in the patients with cerebral embolism, next in patients with cerebral thrombosis and the lowest in patients with lacunar infarction. Cerebral thrombosis was positively associated with smoking (OR: 1.228; 95% CI: 1.013∼1.637), dyslipidemia (OR: 1.264; 95% CI: 1.081∼1.478), and a history of diabetes mellitus (OR: 1.371; 95% CI: 1.075∼1.747); cerebral embolism was positively associated with a history of atrial fibrillation (OR: 3.131; 95% CI: 1.206∼8.128) and a history of rheumatic heart disease (OR: 5.601; 95% CI: 1.561∼20.091); lacunar infarction is positively associated with alcohol consumption, (OR: 1.428; 95% CI: 1.063∼1.919). Conclusion: The incidence rate of poor outcome is the highest in the patients with cerebral embolism among three subtypes of cerebral infarction, there are different risk factors of poor outcome for three subtypes of cerebral infarction.

Full Text Available Omental infarction can be difficult to diagnose preoperatively as imaging may be inconclusive and patients often present in a way that suggests a more common surgical pathology such as appendicitis. Here, a 40-year-old Caucasian man presented to casualty with shortness of breath and progressive right upper abdominal pain, accompanied with right shoulder and neck pain. Exploratory laparoscopy was eventually utilised to diagnose an atypical form of omental infarction that mimics cholecystitis. The vascular supply along the long axis of the segment was occluded initiating necrosis. In this case, the necrotic segment was adherent with the abdominal wall, a pathology not commonly reported in cases of omental infarction.

The purpose of this study was to determine whether transient disturbance of vascular dilation in the peripheral coronary vessels in patients with myocardial infarction in whom coronary recanalization was successfully attained in the acute stage. The subjects were 6 patients with acute myocardial infarction in whom recanalization was successfully attained without a significant coronary stenosis by emergency percutaneous transluminal coronary angioplasty (PTCA). Dipyridamole-loaded thallium-201 myocardial scintigraphy was undertaken during the acute stage (an average of 5 days after PTCA) and during convalescent stage (an average 24 days after PTCA). Defect was seen in the infarcted areas on early images during the acute stage in all 6 patients, and Tl uptake in the infarcted areas was improved during the convalescent stage in 2 of the 6 patients. In these two patients, fill-in phenomenon was seen in the infarcted area during acute stage when images were acquired after re-injection of Tl-201. These findings suggested that transient disturbance of vascular dilation may occur in the peripheral coronary artery vessels in the infarcted area where recanalization was successfully attained in patients with acute myocardial infarction.

An elderly man with a history of several cardiovascular diseases was initially brought to the psychiatric outpatient department by his family because of worsening of recent memory, executive function, and mixed anxious-depressive mood. Gerstmann’s syndrome without obvious motor function impairment and dementia-like features could be observed at first. Emergent brain computed tomography scan revealed new left-middle cerebral artery infarction over the left posterior parietal lobe. This case reminds us that acute cerebral infarction involving the parietal lobe may present as Gerstmann’s syndrome accompanied by cognitive decline mimicking dementia. As a result, emergent organic workups should be arranged, especially for elderly patients at high risk for cerebral vascular accident.Keywords: Gerstmann’s syndrome, dementia, parietal lobe infarction

Chronic subdural hematoma (CSH) is a common disease that is treated with burr hole drainage by neurosurgeons. The outcome of CSH is mostly favorable. We treated 2 cases with bilateral occipital lobe infarction due to CSH. A 57-year-old woman was ambulatory when she visited a clinic for evaluation of headache. One hour after the CT was taken, she developed acute impairment of consciousness, so that she was referred to our hospital. The second patient was a 73-year-old woman with a history of depression who was involved in a traffic accident 5 weeks before admission to our hospital. She was at first admitted to a psychiatric hospital for evaluation of gait disturbance. Three weeks after she was admitted to the psychiatric hospital, she fell into a coma. She was referred to our hospital. Their brain CT on admission revealed compressed ambient and interpeduncular cistern and bilateral CSH. Although burr hole drainage surgery was performed, the 2 patients developed severe sequelae due to occipital lobe infarction caused by central transtentorial herniation.

The experience of cognitive deficits and emotional dysfunction are prevalent in people with multiple sclerosis (PwMS), although research examining their interaction has provided inconsistent findings. The current study examined the ability of executive function to predict psychosocial adjustment in PwMS. One hundred and seven PwMS underwent cognitive assessment and completed measures of stress, depression, anxiety, and quality of life (QoL). There was limited support for a relationship. There was no relationship between objective cognitive tasks and state or trait anxiety, mental health QoL, overall QoL, or stress frequency. The only relationship with depression was found when the Beck Depression Inventory Fast-Screen was used, with a task of planning when the timing element was removed. A measure of error rates on a task of cognitive flexibility predicted physical health QoL, and severity, but not frequency, of stress was predicted by a task of working memory. The results of this study highlight the need for further research into the relationship between cognitive deficits and psychosocial adjustment because of the conflicting findings between studies and call for a common measurement framework for future investigation.

Overgeneral autobiographical memory has been identified as a risk factor for the onset and maintenance of depression. However, little is known about the underlying mechanisms that might explain overgeneral autobiographical memory phenomenon in depression. The purpose of this study was to test the mediation effects of rumination on the relationship between overgeneral autobiographical memory and depressive symptoms. Specifically, the mediation effects of brooding and reflection subtypes of rumination were examined in patients with major depressive disorder. Eighty-seven patients with major depressive disorder completed the 17-item Hamilton Depression Rating Scale, Ruminative Response Scale, and Autobiographical Memory Test. Bootstrap mediation analysis for simple and multiple mediation models through the PROCESS macro was applied. Simple mediation analysis showed that rumination significantly mediated the relationship between overgeneral autobiographical memory and depression symptoms. Multiple mediation analyses showed that brooding, but not reflection, significantly mediated the relationship between overgeneral autobiographical memory and depression symptoms. Our results indicate that global rumination partly mediates the relationship between overgeneral autobiographical memory and depressive symptoms in patients with major depressive disorder. Furthermore, the present results suggest that the mediating role of rumination in the relationship between overgeneral autobiographical memory and depression is mainly due to the maladaptive brooding subtype of rumination.

The radiological features, such as calcification in long bones due to infarcts, resulting from Caisson disease are described by the author on the basis of an extensive experience. The similar localisation of acute "arthralgia" and bone infarcts make it appear probable that the infarcts play a primary role in the production of "osteo-articular" pain. The author stresses the advisability of examining the adjacent portions of the tibia and femur at the initial pre-employment examination, since bone infarcts can be caused by a variety of conditions other than work in Caissons.

Knowledge about user experiences may lead to insights about how to improve treatment activity in Internet-based cognitive behavioral therapy (iCBT) to reduce symptoms of depression and anxiety among people with a somatic disease. There is a need for studies conducted alongside randomized trials, to explore treatment activity and user experiences related to such interventions, especially among people with older age who are recruited in routine care. The aim of the study was to explore treatment activity, user satisfaction, and usability experiences among patients allocated to treatment in the U-CARE Heart study, a randomized clinical trial of an iCBT intervention for treatment of depression and anxiety following a recent myocardial infarction. This was a mixed methods study where quantitative and qualitative approaches were used. Patients were recruited consecutively from 25 cardiac clinics in Sweden. The study included 117 patients allocated to 14 weeks of an iCBT intervention in the U-CARE Heart study. Quantitative data about treatment activity and therapist communication were collected through logged user patterns, which were analyzed with descriptive statistics. Qualitative data with regard to positive and negative experiences, and suggestions for improvements concerning the intervention, were collected through semistructured interviews with 21 patients in the treatment arm after follow-up. The interviews were analyzed with qualitative manifest content analysis. Treatment activity was low with regard to number of completed modules (mean 0.76, SD 0.93, range 0-5) and completed assignments (mean 3.09, SD 4.05, range 0-29). Most of the participants initiated the introduction module (113/117, 96.6%), and about half (63/117, 53.9%) of all participants completed the introductory module, but only 18 (15.4%, 18/117) continued to work with any of the remaining 10 modules, and each of the remaining modules was completed by 7 or less of the participants.

Churg-Strauss syndrome (CSS) is a rare autoimmune disease with small-vessel vasculitis. Neurological manifestation of CSS is common. Central nervous system is less frequently involved than that of peripheral nervous system. We report a case of 60-year-old man who presented with acute onset of right hemiparesis and impaired cognition. The presence of hypereosinophilia, asthma, sinusitis and extravascular eosinophil accumulation led to the diagnosis of Churg-Strauss syndrome. Brain magnetic resonance imaging (MRI) revealed multiple infarcts in bilateral cerebral and cerebellar hemispheres. The neurophysiology study did not reveal peripheral neuropathy. The patient was effectively treated with methylprednisolone, cyclophosphamide and warfarin. Symptoms and signs of central nervous system can be the initial neurological manifestation of CSS patients. CSS should be considered while patients have stroke and hypereosinophilia. In our patient, there is a good response to timely steroid, immunosuppressant and anticoagulant therapies.

The Pathogenesis of Human Myocardial Infarction

Rona, George

1966-01-01

Coronary arteriography, dissection of the coronary arteries and histopathological examination of the heart were carried out in 150 autopsies to study the effect of coronary narrowing and occlusion, of the presence of collaterals, and of coronary artery predominance on the development of myocardial infarction. The thrombosis rate was related to the severity of coronary sclerosis. The development of collaterals was not enhanced by coronary sclerosis and occlusion, and collaterals did not protect the myocardium against reinfarction. Coronary occlusion was regularly demonstrable in recent myocardial infarct cases. The association of atrial and posterior ventricular infarcts was explained by occlusion of their common arterial branch. The interdependence between coronary sclerosis, thrombosis and myocardial infarction in human autopsy material emphasizes the importance of mural coronary artery disease in the genesis of coronary occlusion and myocardial infarction, and it is at variance with statistical data and experimental results.

Bone infarction is common in sickle cell disease; however, involvement of the orbit is not. Only four cases have been reported in the English literature. We describe a patient who presented with headache, proptosis and lid edema due to infarction of the sphenoid bone. The combination of radionuclide bone imaging and computed tomography (CT) of the orbit were useful in differentiating bone infarction from other etiologies of proptosis. (orig.)

Mediation analysis allows the examination of effects of a third variable (mediator/confounder) in the causal pathway between an exposure and an outcome. The general multiple mediation analysis method (MMA), proposed by Yu et al., improves traditional methods (e.g., estimation of natural and controlled direct effects) to enable consideration of multiple mediators/confounders simultaneously and the use of linear and nonlinear predictive models for estimating mediation/confounding effects. Previous studies find that compared with non-Hispanic cancer survivors, Hispanic survivors are more likely to endure anxiety and depression after cancer diagnoses. In this paper, we applied MMA on MY-Health study to identify mediators/confounders and quantify the indirect effect of each identified mediator/confounder in explaining ethnic disparities in anxiety and depression among cancer survivors who enrolled in the study. We considered a number of socio-demographic variables, tumor characteristics, and treatment factors as potential mediators/confounders and found that most of the ethnic differences in anxiety or depression between Hispanic and non-Hispanic white cancer survivors were explained by younger diagnosis age, lower education level, lower proportions of employment, less likely of being born in the USA, less insurance, and less social support among Hispanic patients.

The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n = 16, 100%), hyperattenuation of MCA (n = 3), obscuration of lentiform nucleus (n = 6), loss of insular ribbon (n = 6) and subtle low density in hemisphere (n = 5). The most frequent finding was effacement of cortical sulci in our study, and it was thought to be the most important sign of early acute cerebral infarction

To understand the comorbid characteristics and distribution of combined treatment of Chinese and Western medicine in depressive patients. The descriptive statistic method and association rule were used to analyze the data from 19 general hospitals with 3-A level in China. Among the depressive disorder, the most frequent co-morbid physical diseases included hypertension (24.67%), coronary heart disease (16.10%) and cerebral infarction (12.89%), and the proportion of comorbid changes with the increasing age, from 6.51% to 12.55%, 16.33% and 12.47% for hypertension; from 2.79% to 5.69%, 10.17% and 14.22% for coronary heart disease; from 3.72%, 6.27%, 7.70% and 12.25% for cerebral infarction. The use frequency of the antidepressants is 77.18%, and the use frequency of flupentixol & melitracen is 20.95%. The use frequency of Huoxue Huayu Tongluo of traditional Chinese medicine is 59.97%, with that of 27.91% for Ginkgo biloba extract The combined use frequency of Huoxue Huayu Tongluo of TCM and the antidepressants is the highest, especially for the combined use of Shuxuening injection and fluoxetine. The most frequent comorbid diseases of depression include three kinds of diseases, such as hypertension, coronary heart disease and cerebral infarction, and its proportion gradually increased with the growth of age. The single use frequency of flupentixol & melitracen and G. biloba extract is the highest, while the combined use of Shuxuening injection and fluoxetine is the highest.

A 62-year old patient with a history of chronic anemia associated with malabsorption secondary to short gut syndrome, experienced acute chest pain the second hour after the transfusion of a crossmatch-compatible erythrocyte suspension. His electrocardiogram (ECG) revealed widespread ST-segment depressions and he had an elevated troponin level. Laboratory findings and physical examination did not indicate the presence of immunological or non-immunological blood transfusion reactions. Cardiac catheterization was performed and showed angiographically non-obstructive, atherosclerotic plaques and the absence of vasospasm or thrombus formation. Following antiischemic therapy his symptoms resolved completely. The ECG obtained 24 hours after the emergence of chest pain demonstrated normal sinus rhythm with no ST-T wave changes. We present a rare case of acute myocardial infarction induced following a blood transfusion. To the best of our knowledge, a few cases of acute myocardial infarction associated with blood transfusion have been formally recorded in the medical literature and the clinical experience regarding such cases is indeed quite limited. The present case is reviewed in the context of the relevant literature as a practical resource for clinical practice. Crown Copyright © 2014. Published by Elsevier Ltd. All rights reserved.

Cerebellar cortical infarct cavities are a newly recognised entity associated with atherothromboembolic cerebrovascular disease and worse physical functioning. We aimed to investigate the relationship of cerebellar cortical infarct cavities with symptomatic vertebrobasilar ischaemia and with vascular risk factors. We evaluated the MR images of 46 patients with a recent vertebrobasilar TIA or stroke and a symptomatic vertebral artery stenosis ≥50 % from the Vertebral Artery Stenting Trial (VAST) for the presence of cerebellar cortical infarct cavities ≤1.5 cm. At inclusion in VAST, data were obtained on age, sex, history of vertebrobasilar TIA or stroke, and vascular risk factors. Adjusted risk ratios were calculated with Poisson regression analyses for the relation between cerebellar cortical infarct cavities and vascular risk factors. Sixteen out of 46 (35 %) patients showed cerebellar cortical infarct cavities on the initial MRI, and only one of these 16 patients was known with a previous vertebrobasilar TIA or stroke. In patients with symptomatic vertebrobasilar ischaemia, risk factor profiles of patients with cerebellar cortical infarct cavities were not different from patients without these cavities. Cerebellar cortical infarct cavities are seen on MRI in as much as one third of patients with recently symptomatic vertebral artery stenosis. Since patients usually have no prior history of vertebrobasilar TIA or stroke, cerebellar cortical infarct cavities should be added to the spectrum of common incidental brain infarcts visible on routine MRI.

Proposal for a universal definition of cerebral infarction.

Science.gov (United States)

Saver, Jeffrey L

2008-11-01

Cerebral infarction is a leading cause of disability and death worldwide but has no uniform international definition. Recent diagnostic advances have revised fundamental concepts in cerebral and cardiac ischemia. Cardiologists, already possessed of a nosologic framework distinguishing myocardial infarction from unstable angina on the basis of tissue state, promulgated a new "universal" tissue definition of myocardial infarction incorporating insights afforded by assays of cardiac troponin, a serum biomarker exquisitely sensitive to myocardial injury. Concurrently, vascular neurologists proposed a new tissue, rather than time, criterion to distinguish transient ischemia attack from cerebral infarction, responding to perspectives provided by diffusion MRI and cerebral blood volume CT, imaging biomarkers highly sensitive to neuronal injury. To complete this conceptual realignment, vascular neurology must now advance a clear, uniform, and operationalizable tissue definition of cerebral infarction. This review proposes cerebral infarction be defined as brain or retinal cell death due to prolonged ischemia. This definition categorizes both pannecrosis and neuronal dropout ("complete" and "incomplete" infarcts in classic neuropathologic terminology) as cerebral infarcts. Making the presence of any neuronal or glial cell death essential yields a definition of cerebral infarction that has high relevance to patients, physicians, and policymakers; is more easily applied in clinical practice; fosters action in acute care; harmonizes with myocardial ischemia classification; and focuses diagnostic evaluation on the cause of brain ischemia and the occurrence of end organ injury. The term cerebral infarction should be used when there is evidence of brain or retinal cell death due to cerebral ischemia.

Acute myocardial infarction (MI) is a severe ischemic disease responsible for heart failure and sudden death. Inflammatory cells orchestrate postischemic cardiac remodeling after MI. Studies using mice with defective mast/stem cell growth factor receptor c-Kit have suggested key roles for mast cells (MCs) in postischemic cardiac remodeling. Because c-Kit mutations affect multiple cell types of both immune and nonimmune origin, we addressed the impact of MCs on cardiac function after MI, using the c-Kit-independent MC-deficient (Cpa3(Cre/+)) mice. In response to MI, MC progenitors originated primarily from white adipose tissue, infiltrated the heart, and differentiated into mature MCs. MC deficiency led to reduced postischemic cardiac function and depressed cardiomyocyte contractility caused by myofilament Ca(2+) desensitization. This effect correlated with increased protein kinase A (PKA) activity and hyperphosphorylation of its targets, troponin I and myosin-binding protein C. MC-specific tryptase was identified to regulate PKA activity in cardiomyocytes via protease-activated receptor 2 proteolysis. This work reveals a novel function for cardiac MCs modulating cardiomyocyte contractility via alteration of PKA-regulated force-Ca(2+) interactions in response to MI. Identification of this MC-cardiomyocyte cross-talk provides new insights on the cellular and molecular mechanisms regulating the cardiac contractile machinery and a novel platform for therapeutically addressable regulators. ©2016 Ngkelo et al.

To determine the relationship between ST depression pattern and coronary blood volume in exercise induced myocardial ischemia, exercise-induced ST changes on ECG and regional myocardial blood flow (RMBF) on positron emission computed tomography (PET) were examined. The subjects were 41 patients with myocardial infarction and 30 with angina pectoris, consisting of 55 men and 16 women. Five normal men served as controls. In the group of ST depression, maximum PRP and age were significantly high, and patients with multiple vessel disease accounted for 63.6%. RMBF, as shown on PET, increased by 10% or more after exercise in 71.1% in the group of non ST change and in the control group. In 60.6% of the patients having ST depression, there was a decrease in RMBF or an unfavorable increase in RMBF. Among 33 patients in the group of ST depression, 17 had a sagging type. Of these 17, 12 (70.6%) showed a decrease of RMBF or an unfavorable increase in RMBF, and 10 had triple vessel disease. Sixteen patients had a horizontal type, 8 of whom (50.0%) had a decrease or unfavorable increase in RMBF. These findings suggest that a decrease or unfavorable increase (an increased rate of 10% or less) may be involved in the occurrence of ST depression induced by exercise. In particular, patients with a sagging type ST depression should be monitored during exercise because many of these patients may have triple vessel disease and a decrease or unfavorable increase in RMBF.

Depressed gut? The microbiota-diet-inflammation trialogue in depression.

Koopman, Margreet; El Aidy, Sahar

2017-09-01

According to the WHO reports, around 350 million people worldwide suffer from depression. Despite its high prevalence, the complex interaction of multiple mechanisms underlying depression still needs to be elucidated. Over the course of the last few years, several neurobiological alterations have been linked to the development and maintenance of depression. One basic process that seems to link many of these findings is inflammation. Chronic inflammation has been associated with both biological factors such as excessive neurotransmitter concentrations as well as psychological processes such as adult stress reactivity and a history of childhood trauma. As a balanced microbial community, modulated by diet, is a key regulator of the host physiology, it seems likely that gut microbiota plays a role in depression. The review summarizes the existent literature on this emerging research field and provides a comprehensive overview of the multifaceted links between the microbiota, diet, and depression. Several pathways linking early life trauma, pharmacological treatment effects, and nutrition to the microbiome in depression are described aiming to foster the psychotherapeutic treatment of depressed patients by interventions targeting the microbiota.

Both a large lesion volume and abnormalities in diffusion tensor imaging are independently associated with a poor prognosis after cerebral infarctions. Therefore, we assume that they are associated. This study assessed the associations between lesion volumes and diffusion tensor imaging in patients with a right-sided cerebral infarction. The lesion volumes of 33 patients (age 65.9 ± 8.7, 26 males and 7 females) were imaged using computed tomography (CT) in the acute phase (within 3-4 hours) and magnetic resonance imaging (MRI) in the chronic phase (follow-up at 12 months, with a range of 8-27 months). The chronic-phase fractional anisotropy (FA) and mean diffusivity (MD) values were measured at the site of the infarct and selected white matter tracts. Neurological tests in both the acute and chronic phases, and DTI lateralization were assessed with the Wilcoxon signed-rank test. The effects of thrombolytic therapy (n = 10) were assessed with the Mann-Whitney U test. The correlations between the measured parameters were analysed with Spearman's rho correlation. Bonferroni post-hoc correction was used to compensate for the familywise error rate in multiple comparisons. Several MD values in the right hemisphere correlated positively and FA values negatively with the lesion volumes. These correlations included both lesion area and healthy tissue. The results of the mini-mental state examination and the National Institutes of Health Stroke Scale also correlated with the lesion volume. A larger infarct volume is associated with more pronounced tissue modifications in the chronic stage as observed with the MD and FA alterations

Atorvastatin therapy during the peri-infarct period attenuates left ventricular dysfunction and remodeling after myocardial infarction.

Full Text Available Although statins impart a number of cardiovascular benefits, whether statin therapy during the peri-infarct period improves subsequent myocardial structure and function remains unclear. Thus, we evaluated the effects of atorvastatin on cardiac function, remodeling, fibrosis, and apoptosis after myocardial infarction (MI. Two groups of rats were subjected to permanent coronary occlusion. Group II (n = 14 received oral atorvastatin (10 mg/kg/d daily for 3 wk before and 4 wk after MI, while group I (n = 12 received equivalent doses of vehicle. Infarct size (Masson's trichrome-stained sections was similar in both groups. Compared with group I, echocardiographic left ventricular ejection fraction (LVEF and fractional area change (FAC were higher while LV end-diastolic volume (LVEDV and LV end-systolic and end-diastolic diameters (LVESD and LVEDD were lower in treated rats. Hemodynamically, atorvastatin-treated rats exhibited significantly higher dP/dt(max, end-systolic elastance (Ees, and preload recruitable stroke work (PRSW and lower LV end-diastolic pressure (LVEDP. Morphometrically, infarct wall thickness was greater in treated rats. The improvement of LV function by atorvastatin was associated with a decrease in hydroxyproline content and in the number of apoptotic cardiomyocyte nuclei. We conclude that atorvastatin therapy during the peri-infarct period significantly improves LV function and limits adverse LV remodeling following MI independent of a reduction in infarct size. These salubrious effects may be due in part to a decrease in myocardial fibrosis and apoptosis.

Artificial neural network analysis is found to be far superior to multiple regression when applied to the evaluation of trap quality in the Northern Kuqa Depression, a gas-rich depression of Tarim Basin in western China. This is because this technique can correlate the complex and non-linear relationship between trap quality and related geological factors, whereas multiple regression can only describe a linear relationship. However, multiple regression can work as an auxiliary tool, as it is suited to high-speed calculations and can indicate the degree of dependence between the trap quality and its related geological factors which artificial neural network analysis cannot. For illustration, we have investigated 30 traps in the Northern Kuqa Depression. For each of the traps, the values of 14 selected geological factors were all known. While geologists were also able to assign individual trap quality values to 27 traps, they were less certain about the values for the other three traps. Multiple regression and artificial neural network analysis were, therefore, respectively used to ascertain these values. Data for the 27 traps were used as known sample data, while the three traps were used as prediction candidates. Predictions from artificial neural network analysis are found to agree with exploration results: where simulation predicted high trap quality, commercial quality flows were afterwards found, and where low trap quality is indicated, no such discoveries have yet been made. On the other hand, multiple regression results indicate the order of dependence of the trap quality on geological factors, which reconciles with what geologists have commonly recognized. We can conclude, therefore, that the application of artificial neural network analysis with the aid of multiple regression to trap evaluation in the Northern Kuqa Depression has been quite successful. To ensure the precision of the above mentioned geological factors and their related parameters for each

Objective To test the hypothesis that late-life depression is associated with dementia related pathology. Method Older participants (n=1,965) in 3 longitudinal clinical-pathologic cohort studies who had no cognitive impairment at baseline underwent annual clinical evaluations for a mean of 8.0 years (SD = 5.0). We defined depression diagnostically, as major depression during the study period, and psychometrically, as elevated depressive symptoms during the study period, and established their relation to cognitive outcomes (incident dementia, rate of cognitive decline). A total of 657 participants died and underwent a uniform neuropathologic examination. We estimated the association of depression with 6 dementia related markers (tau tangles, beta-amyloid plaques, Lewy bodies, hippocampal sclerosis, gross and microscopic infarcts) in logistic regression models. Results In the full cohort, 9.4% were diagnosed with major depression and 8.6% had chronically elevated depressive symptoms, both of which were related to adverse cognitive outcomes. In the 657 persons who died and had a neuropathologic examination, higher beta-amyloid plaque burden was associated with higher likelihood of major depression (present in 11.0%; odds ratio = 1.392, 95% confidence interval = 1.088, 1.780) but not with elevated depressive symptoms (present in 11.3%; odds ratio = 0.919, 95% confidence interval = 0.726, 1.165). None of the other pathologic markers was related to either of the depression measures. Neither dementia nor antidepressant medication modified the relation of pathology to depression. Conclusion The results do not support the hypothesis that major depression is associated with dementia related pathology. PMID:26237627

MR imaging has not previously been used to assess infarct size in humans. Short-axis spin-echo cardiac MR imaging was performed in 20 patients who had undergone intravenous thrombolytic therapy and angiography, 10 days after myocardial infarct. A semi-automated computer program was used to outline the infarct region on each section. The outlines were algorithmically stacked and a three-dimensional representation of the infarct was created. The MR imaging infarct volume was then computed using the Simpson rule. Comparison with ventriculographic infarct size as determined by the computed severely hypokinetic segment length showed excellent correlation (r = .84, P < .001)

A wild young male red fox ( Vulpes vulpes ) was found in the mountainous hinterland of Rome (Italy) with a heavily depressed mental status and unresponsive to the surrounding environment. Neurological examination revealed depression, left circling, right head tilt, ventromedial positional strabismus and decreased postural reactions on the left side. Neurological abnormalities were suggestive of central vestibular syndrome. Two consecutive MRIs performed with 30 days interval were compatible with lacunar ischemic infarct in the territory of right caudal cerebral artery and its collateral branches. The lesion epicentre was in the right periaqueductal portion of the rostral mesencephalic tegmentum. Neuroanatomical and neurophysiological correlation between lesion localization and clinical presentation are discussed.

Systematic CT studies on ten patients with persistent ischemic cerebral infarct revealed a constant phenomenon, the fogging effect. The hypodense infarct at the beginning will be isodense, or close to isodense, on the plain CT during the second or third week and at a later stage will be hypodense again. The fogging infarcted area shows homogeneous intensive contrast enhancement. Knowledge of the fogging effect is important for correct interpretation of the CT image and the indication for contrast medium CT. CT without contrast medium may lead to misinterpretation during the second and third week after the onset of cerebral infarction. (orig.) [de

Systematic CT studies on ten patients with persistent ischemic cerebral infarct revealed a constant phenomenon, the fogging effect. The hypodense infarct at the beginning will be isodense, or close to isodense, on the plain CT during the second or third week and at a later stage will be hypodense again. The fogging infarcted area shows homogeneous intensive contrast enhancement. Knowledge of the fogging effect is important for correct interpretation of the CT image and the indication for contrast medium CT. CT without contrast medium may lead to misinterpretation during the second and third week after the onset of cerebral infarction.

Background: Left ventricular hypertrophy (LVH) predisposes to larger infarct size, which may be underestimated by the left ventricular ejection fraction (LVEF) due to supranormal systolic performance often present in patients with LVH. The aim of the study was to compare infarct size and LVEF in patients with ST-segment elevation myocardial infarction (STEMI) and increased left ventricular mass on cardiac magnetic resonance (CMR). Methods: The study included unselected group of 52 patients (61 ± 11 years, 69% male) with first STEMI who had CMR after median 5 days from the onset of the event. Left ventricular hypertrophy (LVH) was defined as left ventricular mass index exceeding 95th percentile of references values for age and gender. Infarct size was assessed with means of late gadolinium enhancement (LGE). Results: LVH was found in 16 patients (31%). In comparison to the rest of the group, patients with LVH had higher absolute and relative infarct mass (p = 0.002 and p = 0.02, respectively). LVH was related to higher prevalence of microvascular obstruction and myocardial haemorrhage and higher number of LV segments with transmural necrosis (p = 0.02, p = 0.01 and p = 0.01, respectively). Despite marked difference in the infarct size between both studied subgroups there was no difference in LVEF and mean number of dysfunctional LV segments. Conclusions: Patients with LVH undergoing STEMI have larger infarct size underestimated by the LV systolic performance in comparison to patients without LVH.

Full Text Available Hepatic infarction is known as a rare disease entity in nontransplant patients. Although a few cases of hepatic infarction have been reported to be linked with invasive procedures, trauma, and hypercoagulability, a case of spontaneous hepatic infarction in a nontransplanted patient has hardly ever been reported. However, many clinical situations of patients with cancer, in particular biliary cancer, can predispose nontransplant patients to hepatic infarction. Besides, the clinical outcome of hepatic infarction in patients with cancer can be worse than in patients with other etiologies. As for treatment, anticoagulation treatment is usually recommended. However, because of its multifactorial etiology and combined complications, treatment of hepatic infarction is difficult and not simple. Herein, we report a case of fatal hepatic infarction that occurred spontaneously during the course of treatment in a patient with gallbladder cancer. Hepatic infarction should be considered as a possible fatal complication in patients during treatment of biliary malignancies.

Full Text Available Cerebrovasculer disease are the most frequent disease of the brain. Cerebellar infarct remains % 1.5-4.2 of these diseases. Etiological factors, lesion localization, symptoms and findings and relationship with prognosis of our patients with cerebellar infarct were investigated in our study. For this purpose, 32 patients were evaluated who were admitted to the Dicle University Medical School Department of Neurology in 1995-2001 hospitalized with the diagnosis of clinically and radiological confirmed cerebellar infarction.All of patients in the study group, 21 (%65.6 were male and 11 (%34.3 female. Age of overall patients ranged between 40 and 75 years with a mean of 57.8±10.2 years. Atherothrombotic infarct was the most frequent reason at the etiologic clinical classification. The most frequently found localization was the posterior inferior cerebellar artery infarct (%50. The leading two risk factors were hypertension (%78.1 and cigarette smoking (%50. The most common sign and symptoms were vertigo (%93.7, vomiting (%75, headache (%68.7 and cerebellar dysfunction findings (%50. The mean duration of hospitalization was 16.3±7.6 days. Overall mortality rate was found to be % 6.2. Finally, the most remarkable risk factors at cerebellar infarct patients are hypertension and atherosclerosis at etiology. We are considering that, controlling of these factors will reduce the appearance frequency of cerebellar infarcts.

We studied whether the amount of dental calculus is associated with death from heart infarction in the dental infection-atherosclerosis paradigm. Participants were 1676 healthy young Swedes followed up from 1985 to 2011. At the beginning of the study all subjects underwent oral clinical examination including dental calculus registration scored with calculus index (CI). Outcome measure was cause of death classified according to WHO International Classification of Diseases. Unpaired t-test, Chi-square tests, and multiple logistic regressions were used. Of the 1676 participants, 2.8% had died during follow-up. Women died at a mean age of 61.5 years and men at 61.7 years. The difference in the CI index score between the survivors versus deceased patients was significant by the year 2009 (P dental visits, dental plaque, periodontal pockets, education, income, socioeconomic status, and pack-years of smoking, CI score appeared to be associated with 2.3 times the odds ratio for cardiac death. The results confirmed our study hypothesis by showing that dental calculus indeed associated statistically with cardiac death due to infarction.

Evidence-based pharmacological and behavioral interventions are often underutilized or inaccessible to persons with multiple sclerosis (MS) who have chronic pain and/or depression. Collaborative care is an evidence-based patient-centered, integrated, system-level approach to improving the quality and outcomes of depression care. We describe the development of and randomized controlled trial testing a novel intervention, MS Care, which uses a collaborative care model to improve the care of depression and chronic pain in a MS specialty care setting. We describe a 16-week randomized controlled trial comparing the MS Care collaborative care intervention to usual care in an outpatient MS specialty center. Eligible participants with chronic pain of at least moderate intensity (≥3/10) and/or major depressive disorder are randomly assigned to MS Care or usual care. MS Care utilizes a care manager to implement and coordinate guideline-based medical and behavioral treatments with the patient, clinic providers, and pain/depression treatment experts. We will compare outcomes at post-treatment and 6-month follow up. We hypothesize that participants randomly assigned to MS Care will demonstrate significantly greater control of both pain and depression at post-treatment (primary endpoint) relative to those assigned to usual care. Secondary analyses will examine quality of care, patient satisfaction, adherence to MS care, and quality of life. Study findings will aid patients, clinicians, healthcare system leaders, and policy makers in making decisions about effective care for pain and depression in MS healthcare systems.

Myocardial infarction caused by ischemia-reperfusion in the coronary vasculature is a focal event characterized by an infarct-core, bordering peri-infarct zone and remote noninfarct zone. Recently, we have reported the first technique, based on laser microdissection pressure catapulting (LMPC), enabling the dissection of infarction-induced biological responses in multicellular regions of the heart. Molecular mechanisms in play at the peri-infarct zone are central to myocardial healing. At the infarct site, myocytes are more sensitive to insult than robust fibroblasts. Understanding of cell-specific responses in the said zones is therefore critical. In this work, we describe the first technique to collect the myocardial tissue with a single-cell resolution. The infarcted myocardium was identified by using a truncated hematoxylin-eosin stain. Cell elements from the infarct, peri-infarct, and noninfarct zones were collected in a chaotropic RNA lysis solution with micron-level surgical precision. Isolated RNA was analyzed for quality by employing microfluidics technology and reverse transcribed to generate cDNA. Purity of the collected specimen was established by real-time PCR analyses of cell-specific genes. Previously, we have reported that the oxygen-sensitive induction of p21/Cip1/Waf1/Sdi1 in cardiac fibroblasts in the peri-infarct zone plays a vital role in myocardial remodeling. Using the novel LMPC technique developed herein, we confirmed that finding and report for the first time that the induction of p21 in the peri-infarct zone is not limited to fibroblasts but is also evident in myocytes. This work presents the first account of an analytical technique that applies the LMPC technology to study myocardial remodeling with a cell-type specific resolution.

This study evaluated the incidence of MR findings showing a hyperintensity rim surrounding multiple sclerosis (MS) plaque on T1-weighted images using image analysis software. We also evaluate the efficacy of this MR finding for differentiating between MS and lacunar infarction. We reviewed T1-weighted images in clinically diagnosed MS patients who underwent MR imaging between February 2006 and July 2007. Two hundred and thirty-nine nodular low signal intensities over 5 mm in minimal diameter were observed in 39 MS patients. To compare the incidence of MR findings, we also reviewed T1-weighted images in randomly selected lacunar infarction patients who underwent MR imaging during the same period. There were 51 nodular low signal intensities over 5 mm in shortest diameter in 34 lacunar infarction patients. After standardization of MR images, we calculated each signal intensity at the plaque margin (M.I.) and surrounding white matter (Wh.I.) using plot-profile analysis. We judged that hyperintensity rim sign was positive when the M.I/Wh.I. ratio was over 1.05. Among 239 T1 low intensity plaques in 39 MS patients, hyperintensity rim sign was positive for 81 (33.9%) plaques in 21 (53.8%) patients. Among 51 T1 low intensity lesions in 34 lacunar infarction patients, hyperintensity rim sign was positive for only one lesion in one patient. There were significant differences in the incidence of hyperintensity rim sign between the two patients groups (p<0.0001). On quantitative analysis using imaging standardization and plot-profile analysis, hyperintensity rim sign was observed in one-third of T1 low intensity MS plaques. This finding seems to be useful to differentiate multiple sclerosis from lacunar infarction. (author)

Various indices of masculinity were compared in 48 men who had recovered from myocardial infarction and in their age-matched controls. We found little evidence to support the idea that myocardial infarction is related to increased androgenic stimulation. The patients with myocardial infarction had no increase in plasma testosterone, muscle thickness, sebum excretion rate, maximal sweat secretion rate, male pattern alopecia or density of terminal body hair, but as a group they had a slight increase in skin and bone thickness compared with the controls.

Full Text Available Introduction : The importance of delay in the restoration of infarct-related artery patency in patients with myocardial infarction was discussed, and actions were undertaken in the Kielce Region aimed at shortening this time within the System for Optimal Management of Acute Myocardial Infarction. Aim of the research: To evaluate the effectiveness of shortening time delays during transport of patients and diagnostics of myocardial infarction in the Kielce Region. Material and methods: Time delays were analysed in 5,934 patients with ST-segment elevation myocardial infarction (STEMI, hospitalised in cardiology wards with interventional cardiology on 24-hour duty, during the period 2008–2012. Time delays were analysed between the onset of myocardial infarction pain and undertaking treatment – T1 and T2 time – within which a patient with myocardial infarction, after admission to hospital, has intervention performed on infarct-related coronary artery. Results : During the period 2008–2012, the median T1 time was successfully shortened from 355 to 203 min, and the T2 time from 101 to 48 min. Conclusions: The effectiveness of the system was confirmed, and the necessity for further improvement of the system indicated.

Cardiovascular disease is a leading cause of death worldwide, where myocardial infarction (MI) is a major category. After infarction, the heart has difficulty providing sufficient energy for circulation, and thus, understanding the heart's energy efficiency is important. We induced MI in a porcine animal model via circumflex ligation and acquired multiple-slice cine magnetic resonance (MR) images in a longitudinal manner-before infarction, and 1 week (acute) and 4 weeks (chronic) after infarction. Computational fluid dynamic simulations were performed based on MR images to obtain detailed fluid dynamics and energy dynamics of the left ventricles. Results showed that energy efficiency flow through the heart decreased at the acute time point. Since the heart was observed to experience changes in heart rate, stroke volume and chamber size over the two post-infarction time points, simulations were performed to test the effect of each of the three parameters. Increasing heart rate and stroke volume were found to significantly decrease flow energy efficiency, but the effect of chamber size was inconsistent. Strong complex interplay was observed between the three parameters, necessitating the use of non-dimensional parameterization to characterize flow energy efficiency. The ratio of Reynolds to Strouhal number, which is a form of Womersley number, was found to be the most effective non-dimensional parameter to represent energy efficiency of flow in the heart. We believe that this non-dimensional number can be computed for clinical cases via ultrasound and hypothesize that it can serve as a biomarker for clinical evaluations.

Thirty patients with acute and subacute cerebral infarction (13 and 17 deep cerebral infarction) were studied with 0.5 T MR unit before and after intravenous injection of Gd-DTPA. Thirteen patients were studied within 7 days after neurological ictus, 17 patients were studied between 7 and 14 days. Two types of abnormal enhancement, cortical arterial and parenchymal enhancement, were noted. The former was seen in 3 of 4 cases of very acute cortical infarction within 4 days after clinical ictus. The latter was detected in all 7 cases of cortical infarction after the 6th day of the ictus, and one patient with deep cerebral infarction at the 12th day of the ictus. Gd-DTPA enhanced MR imaging seems to detect gyral enhancement earlier compared with contrast CT, and depict intra-arterial sluggish flow which was not expected to see on contrast CT scans. (author).

Forty-two dynamic CT studies were performed on 27 patients with cerebral infarction (11 to 75 years of age), and perfusion patterns of low density areas on plain CT were evaluated. The initial studies were performed 1.5 hours to 60 days after acute onset. The following results were obtained. 1) The perfusion pattern in the low density area on plain CT varies among patients at any periods after onset, ranging from absent perfusion pattern to hyperfusion pattern. No consisitent perfusion pattern was obtained at any given time after onset. 2) Repeat dynamic CT revealed that the perfusion pattern in the low density area changed with time variously. 3) The perfusion pattern or change of perfusion pattern did not correlate with outcome of the patient. 4) At an acute stage, when no abnormal findings were obtained on plain CT, dynamic CT revealed abnormal perfusion pattern, enabling early diagnosis of cerebral infarction and estimation of blood perfusion in the infarcted area. In determining the treatment for the cerebral infarction at an acute stage, it is important to know the condition of the blood perfusion in the infarcted area. For the patients in whom recanalization has already taken place, mannitol or steroid might be effective, providing protection against severe brain edema and hemorrhagic infarction. On the other hand, if recanalization has not taken place, revascularization therapy might be worth trying within 6 hours since the onset. It has been said that ischemic brain damage may not be reversed by the revascularization after 6 hours. Dynamic CT is safe, less invasive, convenient and very useful for early diagnosis of the cerebral infarction and determination of the treatment at the acute stage. (J.P.N.)

Full Text Available Abstract Background Myocardial contrast echocardiography has been used for determination of infarct size (IS in experimental models. However, with intermittent harmonic imaging, IS seems to be underestimated immediately after reperfusion due to areas with preserved, yet dysfunctional, microvasculature. The use of exogenous vasodilators showed to be useful to unmask these infarcted areas with depressed coronary flow reserve. This study was undertaken to assess the value of adenosine for IS determination in an open-chest canine model of coronary occlusion and reperfusion, using real-time myocardial contrast echocardiography (RTMCE. Methods Nine dogs underwent 180 minutes of coronary occlusion followed by reperfusion. PESDA (Perfluorocarbon-Exposed Sonicated Dextrose Albumin was used as contrast agent. IS was determined by RTMCE before and during adenosine infusion at a rate of 140 mcg·Kg-1·min-1. Post-mortem necrotic area was determined by triphenyl-tetrazolium chloride (TTC staining. Results IS determined by RTMCE was 1.98 ± 1.30 cm2 and increased to 2.58 ± 1.53 cm2 during adenosine infusion (p = 0.004, with good correlation between measurements (r = 0.91; p 2 and showed no significant difference with IS determined by RTMCE before or during hyperemia. A slight better correlation between RTMCE and TTC measurements was observed during adenosine (r = 0.99; p Conclusion RTMCE can accurately determine IS in immediate period after acute myocardial infarction. Adenosine infusion results in a slight better detection of actual size of myocardial damage.

The locations of cerebral infarctions were studied in 14 patients with tuberculous meningitis (TBM) and 173 patients with noninflammatory ischemic stroke (IS). In patients with TBM, 75% of infarctions occurred in the 'TB zone' supplied by medial striate and thalamoperforating arteries; only 11% occurred in the 'IS zone' supplied by lateral striate, anterior choroidal and thalamogeniculate arteries. In patients with IS, 29% of infarctions occurred in the IS zone, 29% in the subcortical white matter, and 24% in (or involving) the cerebral cortex. Only 11% occurred in the TB zone. Bilaterally symmetrical infarctions of the TB zone were common with TBM (71%) but rare with IS (5%). (orig.)

Particulate matter in urban air is associated with the risk of myocardial infarction in the general population. Very high levels of airborne particles have been detected in the subway system of Stockholm, as well as in several other large cities. This situation has caused concern for negative health effects among subway staff. The aim of this study was to investigate whether there is an increased incidence of myocardial infarction among subway drivers. Data from a population-based case-control study of men aged 40-69 in Stockholm County in 1976-1996 were used. The study included all first events of myocardial infarction in registers of hospital discharges and deaths. The controls were selected randomly from the general population. National censuses were used for information on occupation. Altogether, 22 311 cases and 131 496 controls were included. Among these, 54 cases and 250 controls had worked as subway drivers. The relative risk of myocardial infarction among subway drivers was not increased. It was 0.92 [95% confidence interval (95% CI) 0.68-1.25] when the subway drivers were compared with other manual workers and 1.06 (95% CI 0.78-1.43) when the subway drivers were compared with all other gainfully employed men. Subgroup analyses indicated no influence on the risk of myocardial infarction from the duration of employment, latency time, or time since employment stopped. Subway drivers in Stockholm do not have a higher incidence of myocardial infarction than other employed persons.

Post-traumatic stress disorder (PTSD) is associated with negative impacts on physical health. Victims of a myocardial infarction (MI) who develop PTSD may be particularly affected by these impacts due to their cardiovascular vulnerability. Post-traumatic reactions in this population are not well known. To examine the prevalence of PTSD after MI and its risk factors, and to validate a prediction model for PTSD symptoms. Patients hospitalized for MI (n=477) were recruited in three hospitals. The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and questionnaires concerning PTSD symptoms and general measures were administered to patients during hospitalization and at one-month follow-up. Four per cent of the patients had PTSD and 12% had partial PTSD. The perception of a threat to life, the intensity of acute stress disorder and depression symptoms several days after the MI, a history of referral to a psychologist or psychiatrist, and female sex were risk factors for the intensity of PTSD symptoms in a sequential multiple regression analysis (R=0.634). The prediction model was validated by applying the regression equation to 48 participants who were not included in the initial regression (R=0.633). The risk factors for development of PTSD symptoms identified in the present study could be used to facilitate the detection of patients at risk for developing PTSD symptoms so they can later be offered psychological interventions as needed.

Pulmonary tumor embolism is commonly discovered at autopsy, but is rarely suspected ante-mortem. Microangiopathy is an uncommon and distinct form of simple tumor pulmonary embolism. Here, we present a 52-year-old male with tumor thrombotic microangiopathy and pulmonary infarction, which might have originated from intraductal papillary mucinous tumor of the pancreas. Multiple wedge-shaped consolidations were found initially and aggravated with cavitation. These CT features of pulmonary infarction were pathologically confirmed to result from pulmonary tumor thrombotic microangiopathy.

Sekiai, Yasuhiro

1988-01-01

To evaluate, quantitatively, the viable myocardium in the infarcted zone, we invented the infarct-redistribution map which is produced from images of exercise thallium-201 emission computed tomography performed on 10 healthy subjects and 20 patients with myocardial infarction. The map displayed a left ventricle in which the infarcted area both with and without redistribution, the redistribution area without infarction, and normal perfusion area were shown separated in same screen. In these circumstances, the nonredistribution infarct lesion was found as being surrounded by the redistribution area. Indices of infarct and redistribution extent (defect score, % defect, redistribution ratio (RR) and redistribution index (RI)), were induced from the map and were used for quantitative analysis of the redistribution area and as the basis for comparative discussion regarding regional wall motion of the left ventricle. The quantitative indices of defect score, % defect, RR and RI were consistent with the visual assessment of planar images in detecting the extent of redistribution. Furthermore, defect score and % defect had an inverted linear relationship with % shortening (r = -0.573; p < 0.05, r = -0.536; p < 0.05, respectively), and RI had a good linear relationship with % shortening (r = 0.669; p < 0.01). We conclude that the infarct-redistribution map accurately reflects the myocardial viability and therefore may be useful for quantitative estimation of viable myocardium in the infarcted zone.

Sibutramine is an amphetamine-like drug used for its weight reducing effect. Sibutramine-induced acute coronary syndrome has rarely been reported. We report a case of myocardial infarction associated with the use of sibutramine. A 37-year-old woman presented to an Emergency Department (ED) with intermittent retrosternal chest pain, nausea, and sweating for 3 days. She reported taking one sibutramine tablet each day for 3 days. Blood pressure was 128/89 mm Hg and pulse 66 beats/min. An electrocardiogram revealed ST elevation over the inferior leads and ST depression over leads AVR and V1, the other leads were normal. Serum troponin T was 0.65 microg/L, and sibutramine was identified in her urine. Echocardiography revealed mild hypokinesia over the inferior wall without evidence of acute aortic dissection. The ST segment changes resolved spontaneously within 24 h of cardiac care unit (CCU) admission, a coronary angiogram performed 1 week later was unremarkable, and echocardiography performed 4 weeks after the event showed normal resting regional wall motion. Seventeen medications containing sibutramine as an active ingredient were registered in Hong Kong in 2007. Sibutramine was introduced in the United States in 1997 and in Australia, United Kingdom, and Italy in 2001. Hypertension, tachycardia, dry mouth, and headache are the most commonly reported adverse reactions. Cardiovascular toxicities include tachycardia, palpitation, hypertension, and tachyarrhythmia. We postulate that the myocardial infarction was the result of coronary vasospasm associated with the therapeutic use of sibutramine-containing slimming pills.

Infarct size is a major determinant of prognosis after acute myocardial infarction. Up to date, however, clinically available tests to estimate this size have not been sufficiently accurate. Twelve lead electrocardiogram and wall motion abnormality measurement are not quantitative, and creatine phosphokinase (CPK) measurement is inaccurate in the presence of reperfusion or right ventricular infarction. Methods have been developed to localize and size acute myocardial infarcts with agents that are selectively sequestered in areas of myocardial damage, but previously used agents have lacked sufficient specificity. Antibodies that bind specifically only to damaged myocardial cells may resolve this problem and provide an accurate method for noninvasively measuring infarct size. We determined the accuracy with which infarcted myocardial mass can be measured using single photon emission computed tomography (SPECT) and radiolabeled antimyosin antibodies. Seven patients with acute myocardial infarction and one stable angina patient were injected with 2 mCi of Indium-111 labeled antimyosin antibodies. Planar image and SPECT was performed 24 hours later. None of the patients had history of prior infarcts, and none had undergone reperfusion techniques prior to the study, which was done within 4 days of the attack. Planar image showed all infarct patients to have positive uptakes in the cardiac region. The location of this uptake correlated to the infarct site as indicated by electrocardiography in most of the cases. The angina patient, however, showed no such abnormal uptake. Infarct size was determined from transverse slices of the SPECT image using a 45% threshold value obtained from a phantom study. Measured infarct size ranged from 40 to 192 gr. There was significant correlation between the infarct size measured by SPECT and that estimated from serial measurements of CPK (r=0.73, p<0,05). These date suggest that acute myocardial infarct size can be accurately measured

A total of 231 patients suffering from a first acute myocardial infarction were randomly allocated within 4 hours following the onset of symptoms either to anistreplase or anisoylated plasminogen streptokinase activator complex (APSAC), 30 U over 5 minutes, or to conventional heparin therapy, 5000 IU in bolus injection. Heparin was reintroduced in both groups 4 h after initial therapy at a dosage of 500 IU/kg per day. A total of 112 patients received anistreplase and 119 received heparin within a mean period of 188 +/- 62 min following the onset of symptoms. Infarct size was estimated from single photon emission computerized tomography and expressed in percentage of the total myocardial volume. The patency rate of the infarct-related artery was 77% in the anistreplase group and 36% in the heparin group (p less than 0.001). Left ventricular ejection fraction determined from contrast angiography was significantly higher in the anistreplase group than in the heparin group (6 absolute percentage point difference). A significant 31% reduction in infarct size was found in the anistreplase group (33% for the anterior wall infarction subgroup [p less than 0.05] and 16% for the inferior wall infarction subgroup, NS). A close inverse relation was found between the values of left ventricular ejection fraction and infarct size (r = -.73, p less than 0.01). In conclusion, early infusion of anistreplase in acute myocardial infarction produced a high early patency rate, a significant limitation of infarct size, and a significant preservation of left ventricular systolic function, mainly in the anterior wall infarctions.

Objective: To study the relationship between blood uric acid and acute cerebral infarction. Methods: The level of blood uric acid and prevalence of hyperuricemia (HUA) were compared in 360 patients with acute cerebral infarction and 300 patients without it. According to the level of blood uric acid, 360 acute cerebral infarction patients were divided into HUA and normouricemia (NUA) groups. Age, sex, body mass index (BMI), blood glucose and total cholesterol were compared between the HUA and NUA group. The degree of neurological functional defection was compared between the two groups when patients were attacked by acute cerebral infarction. After a recovery treatment, the neurological functional defection of the two groups was compared a second time. Results: (1)The average blood uric acid level and prevalence of HUA were higher in patients with acute cerebral infarction. (2) The BMI, blood glucose and total cholesterol were higher in HUA group than in NUA group. (3) The neurological functional defection was more serious in HUA group when patients were attacked by acute cerebral infarction and after a recovery treatment. Conclusion: Hyperuricemia is related to acute cerebral infarction. (authors)

It is becoming clear that the comorbidity of depression and cardiovascular disease does not occur by chance but rather is an inevitable consequence of the relationship between the conditions. Depression in patients with cardiovascular disease is a significant risk factor for developing symptomatic and fatal ischemic heart disease. Moreover, depressed patients have a higher than expected rate of sudden cardiovascular death. Therefore, appropriate treatment of patients with depression and cardiovascular disease cannot be restricted to considerations of either depression or cardiovascular disease in isolation. The tricyclic antidepressants (TCAs) have various effects on the cardiovascular system, including Type IA antiarrhythmic activity that has been associated with an increased risk of mortality in post-myocardial infarction patients. The selective serotonin reuptake inhibitors (SSRIs) are not associated with adverse cardiac effects. The SSRI paroxetine was compared with a therapeutic level of the TCA nortriptyline in a randomized, controlled study and demonstrated a benign cardiovascular profile, while the TCA induced a significantly higher rate of serious adverse cardiovascular events. On the basis of this favorable cardiovascular profile, the SSRIs should therefore be the preferred choice for the treatment of most patients with comorbid depression and cardiovascular disease. Investigation of putative pathophysiologic mechanisms linking depression and cardiovascular mortality, such as the role of platelet activation, will form the basis for further investigation of antidepressant treatments in order to establish if the antidepressants have a beneficial effect on the prognosis of cardiovascular diseases.

Introduction: Splenic and renal infarctions are usually related to vascular disease or haematologic abnormalities. Their association is infrequent and rarely observed in trauma. In this study, we analyze our data to look at the occurrence of renal and splenic infarctions based on CT findings in a period of 4 years. Materials and Methods: We retrospectively reviewed the imaging findings of 84 patients admitted to our Department of Diagnostic Imaging from June 1998 to December 2002, who underwent emergency abdominal spiral CT examination and in whom there was evidence of splenic and/or renal infarction. Results: We found 40 cases of splenic infarction and 54 cases of renal infarction, associated in 10 patients. In 26 patients, there was also evidence of intestinal infarction. A traumatic origin was found in 19 cases; non-traumatic causes were found in 65 patients. Association between renal and splenic infarction in the same patient was related to trauma in two cases. Conclusions: Although renal and splenic infarctions are a common manifestation of cardiac thromboembolism, other systemic pathologies, infections or trauma may lead to this occurrence. Renal infarction may be clinically and/or surgically managed with success in most cases. There are potential complications in splenic infarction, such as development of pseudocysts, abscesses, hemorrhage, subcapsular haematoma or splenic rupture; splenectomy in these cases may be necessary. Some patients with splenic and/or renal infarction may be clinically asymptomatic. The high accuracy of CT examination is needed to allow a correct evaluation of infarcted organs.

Following pulmonary infarction, three patients developed the classical signs and symptoms of the Dressler syndrome associated with persistent left pleural effusion. Each responded dramatically to corticosteroid therapy. While the pathogenesis of this "Post-Pulmonary Infarction syndrome," like the Dressler syndrome, is unclear, the response to corticosteroid therapy is both dramatic and diagnostic and may spare the patient prolonged discomfort and unnecessary diagnostic procedures.

The Tc-99m sestamibi perfusion SPECT scintigraphy in acute myocardial infarction is a feasible method to assess the size of area at risk and the residual blood flow to this area as the most important determinants of final infarct size without any delay in treatment. In combination with a follow-up study final infarct size as well as myocardial salvage can be quantified. Clinical indications for the use of Tc-99m sestamibi scintigraphy are the noninvasive identification of arterial occlusion in patients suspected to acute myocardial infarction without electrocardiographic ST-elevation and the assessment of reperfusion success. In clinical trials Tc-99m sestamibi scintigraphy has proven to be a useful method to assess the impact of varying reperfusion therapies. The present review article discusses the indication, the study protocol, the interpretation of results and the clinical and scientifically importance of this method. (orig.) [de

Metabolic alterations in experimental models of depression

Full Text Available Introduction: Major depressive disorder is one of the most prevalent psychiatric disorders and is associated with a severe impact on the personal functioning, thus with incurring significant direct and indirect costs. The presence of depression in patients with medical comorbidities increases the risks of myocardial infarction and decreases diabetes control, and adherence to treatment. The mechanism through which these effects are produced is still uncertain. Objectives of this study were to evaluate the metabolic alterations in female Wistar rats with induced depression, with and without administration of Agomelatine. The methods included two experiments. All data were analyzed by comparison with group I (control, and with each other. In the first experiment we induced depression by: exposure to chronic mild stress-group II; olfactory bulbectomy-group III; and exposure to chronic mild stress and hyperlipidic/ hyper caloric dietgroup IV. The second experiment was similar with the first but the rats received Agomelatine (0.16mg/ animal: group V (depression induced through exposure to chronic mild stress, VI (depression induced through olfactory bulbectomy and VII (depression induced through exposure to chronic mild stressing hyperlipidic/ hypercaloric diet. Weight, cholesterol, triglycerides and glycaemia were measured at day 0 and 28, and leptin value was measured at day 28. The results in the 1st experiment revealed significant differences (p<0.01 for weight and cholesterol in Group IV, for triglycerides in groups III and IV (p<0.001, and for glycaemia in group II. The 2nd experiment revealed significant differences (p<0.001 in group VII for weight and triglycerides, and in groups V and VI for triglycerides (p<0.01. In conclusion, significant correlations were found between high level of triglycerides and depression induced by chronic stress and olfactory bulbectomy. Agomelatine groups had a lower increase of triglycerides levels.

In acute myocardial infarction (AMI) treated by primary percutaneous coronary intervention (PCI), there is a direct relationship between myocardial damage and consequent left ventricular (LV) functional impairment. It is however unclear whether there is a safety threshold below which infarct size does not significantly affect LV ejection fraction (EF). The aim of this study was to evaluate the relationship between infarct size and LVEF in AMI patients treated by successful PCI using a specific statistical approach to identify a possible safety threshold. Among patients with recent AMI submitted to perfusion gated single photon emission computed tomography (SPECT) to define the infarct size, the data of 427 subjects with sizable infarct size were considered. The relationship between infarct size and LVEF was analysed using a simple segmented regression (SSR) model and an iterative algorithm based on robust least squares (RLS) for parameter estimation. The RLS algorithm detected two break points in the SSR model, set at infarct size values of 11.0 and 51.5 %. Because the slope coefficients of the two extreme segments of the regression line were not significant, by constraining such segments to zero slope in the SSR model, the lower break point was identified at infarct size = 8 % and the upper one at 45 %. Using a rigorous statistical approach, it is possible to demonstrate that below a threshold of 8 % the infarct size apparently does not affect the LVEF and therefore a safety threshold could be set at this value. Furthermore, the same analysis suggests that the relationship between infarct size and LVEF impairment is lost for an infarct size > 45 %.

Technetium-99m-stannous pyrophosphate scintiphotos were evaluated for diagnosing and quantitating myocardial infarct (MI) extension in sedated dogs. Infarction and extension were produced by serial left anterior descending coronary artery ligations at 0 and 48 hours. We compared serial scintiphoto data with regional myocardial blood flow (MBF) (microsphere technique) and infarct histopathology. In eight control dogs, the scintigraphic MI area was stable at 24, 48, and 72 hours. In each of 11 dogs undergoing extension, the MI area increased after the 48-hour occlusion, averaging a 48.9% increase (p < 0.001). Grossly, most extensions were mixtures of confluent necrosis and moderate (patchy) necrosis. MBF to confluent infarct tissue decreased significantly, allowing the documentation of extension by totaling the grams of newly flow-deprived tissue, but patchy infarct tissue had little flow deprivation, making it difficult to quantitate this type of extension accurately by flow criteria alone. Rarely, extension could be diagnosed using conventional histologic criteria. We concluded that the scintiphoto MI area was related quantitatively to infarct weight in both control and extension. However, it was not possible to determine that an increase in the MI scintiphoto area was an accurate predictor of the degree of extension using independent flow or pathologic criteria

There is limited knowledge regarding how depressive symptoms and a cluster of specific mood symptoms in people with multiple sclerosis (MS) vary over time and how they are influenced by contributing factors. Therefore, the aims of this study were a) to describe variations over 2 years in the occurrence of depressive symptoms and mood symptoms in a sample of people with MS, and b) to investigate the predictive value of sex, age, coping capacity, work status, disease severity, disease course, fatigue, cognition, frequency of social/lifestyle activities, and perceived impact of MS on health, on the occurrence of depressive symptoms and mood symptoms. Through using a protocol of measures of functioning and perceived impact of MS on health, comprising of the Beck Depression Inventory, 219 people with MS were assessed at 0, 12 and 24 months. Predictive values were explored with Generalised Estimating Equations. Proportions with depressive symptoms varied significantly (p < 0.001) from 21 to 30% between the three time points. Proportions with mood symptoms varied significantly (p < 0.001) from 14 to 17% between the three time points. Weak coping capacity and reduced frequency of social/lifestyle activities predicted the occurrence of depressive symptoms and mood symptoms, as did the psychological impact of MS on health in interaction with time. For people with MS of working age, not working predicted the occurrence of depressive symptoms and mood symptoms, as did the physical impact of MS on health on the occurrence of mood symptoms. The occurrence of depressive symptoms and mood symptoms in people with MS vary over a 2-year time period; almost half have depressive symptoms at least once. Health care services should develop strategies aimed at identifying people with MS who are depressed or who develop depressive symptoms. Interventions for alleviating depressive symptoms should consider the individual's coping capacity and perceived impact of MS on health, and

Estimation of infarct size by myocardial emission computed tomography with thallium-201 and its relation to creatine kinase-MB release after myocardial infarction in man

Tamaki, S.; Nakajima, H.; Murakami, T.

1982-01-01

Emission computed tomography (ECT) for thallium-201 ( 201 Tl) myocardial imaging was evaluated in estimating infarct size (IS). In 18 patients in whom IS was estimated enzymatically at the time of the acute episode, planar 201 Tl perfusion scintigraphy and ECT with a rotating gamma camera were performed 4 weeks after the first myocardial infarction. From the size of 201 Tl perfusion defects, the infarct area in planar images and the infarct volume in reconsturcted ECT images were measured by computerized planimetry. When scintigraphic IS was compared with the accumulated creatine kinase-MB isoenzyme release (CK-MBr), infarct volume determined from ECT correlated closely with CK-MBr (r=0.89), whereas infarct area measured from planar images correlated less satisfactorily with the enzymatic IS (for an average infarct area from three views, r=0.69; for the largest infarct area, r=0.73). Although conventional scintigraphic evaluation is useful for detecting and localizing infarction, quantification of ischemic injury with this two-dimensional technique has a significant inherent limitation. The ECT approach can provide a more accurate three-dimensional quantitative estimate of infarction, and can corroborate the enzymatic estimate of IS

Malignant Hemispheric Cerebral Infarction Associated with Idiopathic Systemic Capillary Leak Syndrome

Directory of Open Access Journals (Sweden)

Kei Miyata

2013-10-01

Full Text Available Idiopathic systemic capillary leak syndrome (ISCLS is a rare condition that is characterized by unexplained episodic capillary hyperpermeability due to a shift of fluid and protein from the intravascular to the interstitial space. This results in diffuse general swelling, fetal hypovolemic shock, hypoalbuminemia, and hemoconcentration. Although ISCLS rarely induces cerebral infarction, we experienced a patient who deteriorated and was comatose as a result of massive cerebral infarction associated with ISCLS. In this case, severe hypotensive shock, general edema, hemiparesis, and aphasia appeared after serious antecedent gastrointestinal symptoms. Progressive life-threatening ischemic cerebral edema required decompressive hemicraniectomy. The patient experienced another episode of severe hypotension and limb edema that resulted in multiple extremity compartment syndrome. Treatment entailed forearm and calf fasciotomies. Cerebral edema in the ischemic brain progresses rapidly in patients suffering from ISCLS. Strict control of fluid volume resuscitation and aggressive diuretic therapy may be needed during the post-leak phase of fluid remobilization.

Systematic reviews examining associations of depressive disorder with coronary heart disease and stroke produce mixed results. Failure to consider reverse causation and dose-response patterns may have caused inconsistencies in evidence. This prospective cohort study on depressive disorder, coronary heart disease, and stroke analysed reverse causation and dose-response effects using four 5-year and three 10-year observation cycles (total follow up 24 years) based on multiple repeat measures of exposure. Participants in the Whitehall II study (n = 10,036, 31,395 person-observations, age at start 44.4 years) provided up to six repeat measures of depressive symptoms via the 30-item General Health Questionnaire (GHQ-30) and one measure via Center for Epidemiologic Studies Depression Scale (CES-D). The cohort was followed up for major coronary events (coronary death/nonfatal myocardial infarction) and stroke (stroke death/morbidity) through the national mortality register Hospital Episode Statistics, ECG-screening, medical records, and self-report questionnaires. GHQ-30 caseness predicted stroke over 0-5 years (age-, sex- and ethnicity-adjusted HR 1.60, 95% CI 1.1-2.3) but not over 5-10 years (HR 0.94, 95% CI 0.6-1.4). Using the last 5-year observation cycle, cumulative GHQ-30 caseness was associated with incident coronary heart disease in a dose-response manner (1-2 times a case: HR 1.12, 95% CI 0.7-1.7; 3-4 times: HR 2.06, 95% CI 1.2-3.7), and CES-D caseness predicted coronary heart disease (HR 1.81, 95% CI 1.1-3.1). There was evidence of a dose-response effect of depressive symptoms on risk of coronary heart disease. In contrast, prospective associations of depressive symptoms with stroke appeared to arise wholly or partly through reverse causation.

BACKGROUND: The amino-terminal propeptide of type III procollagen (PIIINP) is a marker of type III collagen synthesis, which has previously been shown to correlate with infarct size in nonthrombolyzed myocardial infarction (MI) and to provide prognostic information after MI. METHODS AND RESULTS......: The relationship between PIIINP and changes of left ventricular (LV) function was studied in 47 consecutive patients with first acute MI and 16 control subjects. Serum PIIINP analysis was measured daily during hospitalization and on days 90, 180, and 360. LV function was assessed by echocardiography on days 1, 5......, 90, and 360. Patients with MI were stratified according to their serum PIIINP value at day 4 (group A, 5.0 microg/L). On arrival, LV function and size were comparable between groups A (n=31) and B (n=16). LV ejection fraction, initially depressed (day 1: group A, 47...

PET has some disadvantage in the imaging of small animal due to poor resolution. With the advent of microPET scanner, it is possible to image small animals. However, the image quality was not good enough as human image. Due to larger brain, cat brain imaging was superior to mouse or rat. In this study, we established the cat brain infarction model and evaluate it and its temporal change using microPET scanner. Two adult male cats were used. Anesthesia was done with xylazine and ketamine HCI. A burr hole was made at 1 cm right lateral to the bregma. Collagenase type IV 10 {mu}l was injected using 30 G needle for 5 minutes to establish the infarction model. {sup 18}F-FDG microPET (Concorde Microsystems Inc., Knoxville, TN) scans were performed 1, 11 and 32 days after the infarction. In addition, {sup 18}F-FDG PET scans were performed using human PET scanner (Gemini, Philips medical systems, CA, USA) 13 and 47 days after the infarction. Two cat brain infarction models were established. The glucose metabolism of an infarction lesion improved with time. An infarction lesion was also distinguishable in the human PET scan. We successfully established the cat brain infarction model and evaluated the infarcted lesion and its temporal change using {sup 18}F-FDG microPET scanner.

We recently found that increases in plasma levels of protein-conjugated acrolein and polyamine oxidases, enzymes that produce acrolein, are good markers for stroke. The aim of this study was to determine whether the level of protein-conjugated acrolein is increased and levels of spermine and spermidine, the substrates of acrolein production, are decreased at the locus of infarction. A unilateral infarction was induced in mouse brain by photoinduction after injection of Rose Bengal. The volume of the infarction was analyzed using the public domain National Institutes of Health image program. The level of protein-conjugated acrolein at the locus of infarction and in plasma was measured by Western blotting and enzyme-linked immunosorbent assay, respectively. The levels of polyamines at the locus of infarction and in plasma were measured by high-performance liquid chromatography. The level of protein-conjugated acrolein was greatly increased, and levels of spermine and spermidine were decreased at the locus of infarction at 24 hours after the induction of stroke. The size of infarction was significantly decreased by N-acetylcysteine, a scavenger of acrolein. It was also found that the increases in the protein-conjugated acrolein, polyamines, and polyamine oxidases in plasma were observed after the induction of stroke. The results indicate that the induction of infarction is well correlated with the increase in protein-conjugated acrolein at the locus of infarction and in plasma.

The purpose of the present study is to evaluate diffusional anisotropy of white matter in patients with multiple lacunar infarcts using diffusion-weighted echo-planar imaging (DW-EPI), and to examine the relationship between diffusional anisotropy and global cognitive ability as assessed by the mini-mental status examination (MMSE). In particular, we focused on the parameter changes for the corpus callosum as a marker for disconnection of the associative cortices. Twenty-nine patients divided into 2 cognitive level groups (low MMSE, n=16; high MMSE, n=13) and 8 normal controls were examined with a GE 1.5 T Horizon system. Three series of DW-EPI images were obtained using the following epidw g ·psd TM sequence: TR/TE=6500/120 ms, single shot, 6.5 mm slice thickness and 1.5 mm gap transaxial sections of the whole brain, with b-factors of 0 and 710 along each x- and y-axial direction. The parametric maps for apparent diffusion coefficient (ADC) in each direction, ADC(x) and ADC(y), and their rate map (ADC rate=ADC(x)/ADC(y)) were created on a pixel-by-pixel basis. ROI data were extracted from images of the corpus callosum and bilateral optic radiata. As a result, the ADC(x) was markedly larger for corpus callosum than that for optic radiata, whereas the ADC(y) showed an inverse trend, attributable to regional differences of diffusional anisotropy. In corpus callosum, however, the ADC(y) values were observed to increase with the level of disease severity, resulting in a decrease of the ADC rate. Notably, there was a significant difference between the three groups for callosal genu, with a slight positive correlation between the ADC rate and the MMSE scores. Our study suggests that a relationship exists between the reduction of diffusional anisotropy in callosal genu and the global cognitive impairment seen in patients with multiple lacunar infarcts.

Although studies have demonstrated significant negative relationships between quality of life (QOL), fatigue, and the most common psychological symptoms (depression, anxiety, stress), the main ambiguity of previous studies on QOL is in the relative importance of these predictors. Also, there is lack of adequate knowledge about the actual contribution of each of them in the prediction of QOL dimensions. Thus, the main objective of this study is to assess the role of fatigue, depression, anxiety, and stress in relation to QOL of multiple sclerosis (MS) patients. One hundred and sixty-two MS patients completed the questionnaire on demographic variables, and then they were evaluated by the Persian versions of Short-Form Health Survey Questionnaire (SF-36), Fatigue Survey Scale (FSS), and Depression, Anxiety, Stress Scale-21 (DASS-21). Data were analyzed by Pearson correlation coefficient and hierarchical regression. Correlation analysis showed a significant relationship between QOL elements in SF-36 (physical component summary and mental component summary) and depression, fatigue, stress, and anxiety (P depression, and anxiety were identified as the physical component summary predictor variables. Anxiety was found to be the most powerful predictor variable amongst all (β = -0.46, P depression as the only significant mental component summary predictor variable (β = -0.39, P anxiety, fatigue, and depression in physical dimensions and the role of depression in psychological dimensions of the lives of MS patients. In addition, the findings of this study indirectly suggest that psychological interventions for reducing fatigue, depression, and anxiety can lead to improved QOL of MS patients.

A 22-year-old man complaining of persisting high fever and right hypochondralgia was admitted to our hospital for infectious mononucleosis with splenic infarction detected by computed tomography. The splenic infarction deteriorated with a marked elevation of inflammatory parameters. This necessitated the commencement of methylprednisolone pulse therapy, resulting in prompt amelioration of inflammation and a reduction in cytokine levels. Including our case, only 9 cases of mononucleosis with splenic infarction have been reported to date; however, splenic infarction should be considered because it is a significant complication of infectious mononucleosis.

Mario Ricciardi

2017-06-01

Full Text Available A wild young male red fox (Vulpes vulpes was found in the mountainous hinterland of Rome (Italy with a heavily depressed mental status and unresponsive to the surrounding environment. Neurological examination revealed depression, left circling, right head tilt, ventromedial positional strabismus and decreased postural reactions on the left side. Neurological abnormalities were suggestive of central vestibular syndrome. Two consecutive MRIs performed with 30 days interval were compatible with lacunar ischemic infarct in the territory of right caudal cerebral artery and its collateral branches. The lesion epicentre was in the right periaqueductal portion of the rostral mesencephalic tegmentum. Neuroanatomical and neurophysiological correlation between lesion localization and clinical presentation are discussed.

To evaluate the usefulness of single photon emission computed tomography (SPECT) with technetium-99m-pyrophosphate (/sup 99m/Tc-PYP) for estimating infarct size, we compared SPECT data with maximum creatine phosphokinase values. Background threshold was established in a series of phantom experiments. When a 40 % cut-off was applied, the SPECT data most closely approximated actual phantom volumes. Therefore, the 40 % cut-off level was used in the present study. In 10 patients with acute myocardial infarction, planar /sup 99m/Tc-PYP myocardial scintigraphy and SPECT using a rotating gamma camera were performed two days after the initial myocardial infarction episode. The maximum creatine phosphokinase value (CPKmax) was also measured repeatedly following the episode. When the infarct size measured by SPECT using transaxial images and calculated by the pixel counts, it correlated very closely with CPKmax (r = 0.94). Most studies so far have reported that the CPKmax level reflects infarct size. We conclude that the infarct size as measured by /sup 99m/Tc-PYP SPECT closely approximates the actual infarct size, and that this method is useful to determine the severity of infarcts clinically. Among the 10 patients in this series, three of five with infarcts greater than 60 ml died of pump failure. Therefore, we may be able to predict prognosis after accumulating more such cases and improving the methodology.

Cerebral infarction (CI) is one of severe diseases of central nervous system in neonates, and some infants with CI could have poor prognosis in the long term. This study aimed to analyze the clinical data and prognosis of all neonatal cases with cerebral infarction in recent years and to help future clinical work. Totally 58 neonatal cases with CI admitted to NICU of the hospital from January 1999 to December 2010 were included in this study. We analyzed all clinical data and prognosis by retrospective analysis. Fifty-two term babies and six preterm babies were included. There were altogether 51 cases with asphyxia and 7 with hemorrhagic cerebral infarction. Perinatal hypoxia-ischemia was the most common high-risk factor and it accounted for 46.6%. Seizure was the most frequent initial symptom and the most common clinical manifestation (accounted for 77.6%), and it was followed by intermittent cyanosis, apnea and lethargy. Cerebral CT scan and magnetic resonance imaging were major methods to help to make the diagnosis and they also had close relation with prognosis. Diffusion weighted imaging was very helpful to diagnose infarction in early stage. Left middle cerebral artery was the most common artery to be involved. Supportive therapy and symptomatic treatment were the main methods in the acute stage of neonatal cerebral infarction. Those babies with poor prognosis mostly had large infarction involving cerebral hemisphere, thalamus and basal ganglia. Neonatal cerebral infarction was a severe brain injury affecting long tern nervous system prognosis. Perinatal hypoxia was the most common high-risk factor and seizure was the most frequent initial symptom. Diffusion weighted imaging was valuable to diagnose infarction in early stage. Most of infants with poor prognosis had large infarction involving hemisphere, thalamus and basal ganglia. Early diagnosis with brain imaging would be helpful for rehabilitation therapy and improving prognosis.

Full Text Available Abstract Background To explore the pathological changes of three-dimension structure of ventricular myocardial fibers after anterior myocardial infarction in dog heart. Methods Fourteen acute anterior myocardial infarction models were made from healthy dogs (mean weight 17.6 ± 2.5 kg. Six out of 14 dogs with old myocardial infarction were sacrificed, and their hearts were harvested after they survived the acute anterior myocardial infarction for 3 months. Each heart was dissected into ventricular myocardial band (VMB, morphological characters in infarction region were observed, and infarct size percents in descending segment and ascending segment were calculated. Results Six dog hearts were successfully dissected into VMB. Uncorresponding damages in myocardial fibers of descending segment and ascending segment were found in apical circle in anterior wall infarction. Infarct size percent in the ascending segment was significantly larger than that in the descending segment (23.36 ± 3.15 (SD vs 30.69 ± 2.40%, P = 0.0033; the long axis of infarction area was perpendicular to the orientation of myocardial fibers in ascending segment; however, the long axis of the infarction area was parallel with the orientation of myocardial fibers in descending segment. Conclusions We found that damages were different in both morphology and size in ascending segment and descending segment in heart with myocardial infarction. This may provide an important insight for us to understand the mechanism of heart failure following coronary artery diseases.

Nitric Oxide-Related Biological Pathways in Patients with Major Depression.

Full Text Available Major depression is a well-known risk factor for cardiovascular diseases and increased mortality following myocardial infarction. However, biomarkers of depression and increased cardiovascular risk are still missing. The aim of this prospective study was to evaluate, whether nitric-oxide (NO related factors for endothelial dysfunction, such as global arginine bioavailability, arginase activity, L-arginine/ADMA ratio and the arginine metabolites asymmetric dimethylarginine (ADMA and symmetric dimethylarginine (SDMA might be biomarkers for depression-induced cardiovascular risk.In 71 in-patients with major depression and 48 healthy controls the Global Arginine Bioavailability Ratio (GABR, arginase activity (arginine/ornithine ratio, the L-arginine/ADMA ratio, ADMA, and SDMA were determined by high-pressure liquid chromatography. Psychiatric and laboratory assessments were obtained at baseline at the time of in-patient admittance and at the time of hospital discharge.The ADMA concentrations in patients with major depression were significantly elevated and the SDMA concentrations were significantly decreased in comparison with the healthy controls. Even after a first improvement of depression, ADMA and SDMA levels remained nearly unchanged. In addition, after a first improvement of depression at the time of hospital discharge, a significant decrease in arginase activity, an increased L-arginine/ADMA ratio and a trend for increased global arginine bioavailability were observed.Our study results are evidence that in patients with major depression ADMA and SDMA might be biomarkers to indicate an increased cardiovascular threat due to depression-triggered NO reduction. GABR, the L-arginine/ADMA ratio and arginase activity might be indicators of therapy success and increased NO production after remission.

Cardiac macrophage biology in the steady-state heart, the aging heart, and following myocardial infarction

Ma, Yonggang; Mouton, Alan J.; Lindsey, Merry L.

2018-01-01

Macrophages play critical roles in homeostatic maintenance of the myocardium under normal conditions and in tissue repair after injury. In the steady-state heart, resident cardiac macrophages remove senescent and dying cells and facilitate electrical conduction. In the aging heart, the shift in macrophage phenotype to a proinflammatory subtype leads to inflammaging. Following myocardial infarction (MI), macrophages recruited to the infarct produce both proinflammatory and anti-inflammatory mediators (cytokines, chemokines, matrix metalloproteinases, and growth factors), phagocytize dead cells, and promote angiogenesis and scar formation. These diverse properties are attributed to distinct macrophage subtypes and polarization status. Infarct macrophages exhibit a proinflammatory M1 phenotype early and become polarized toward an anti-inflammatory M2 phenotype later post- MI. Although this classification system is oversimplified and needs to be refined to accommodate the multiple different macrophage subtypes that have been recently identified, general concepts on macrophage roles are independent of subtype classification. This review summarizes current knowledge about cardiac macrophage origins, roles, and phenotypes in the steady state, with aging, and after MI, as well as highlights outstanding areas of investigation.

We propose a joint Source-Based Analysis (jSBA) framework to identify brain structural variations in patients with Major Depressive Disorder (MDD). In this framework, features representing position, orientation and size (i.e. pose), shape, and local tissue composition are extracted. Subsequently, simultaneous analysis of these features within a joint analysis method is performed to generate the basis sources that show signi cant di erences between subjects with MDD and those in healthy control. Moreover, in a cross-validation leave- one-out experiment, we use a Fisher Linear Discriminant (FLD) classi er to identify individuals within the MDD group. Results show that we can classify the MDD subjects with an accuracy of 76% solely based on the information gathered from the joint analysis of pose, shape, and tissue composition in multiple brain structures.

Acute myocardial infarcts

International Nuclear Information System (INIS)

Just, H.

1988-01-01

Acute myocardial infarction is a major complication of stenosing coronary artery disease and constitutes the most frequent single cause of death. It is caused by thrombotic occlusion of one of the major epicardial coronary arterial branches in most cases. Sudden death due to ventricular fibrillation is responsible for the majority of early fatalities. In 60% of all fatal infarcts, death occurs within 1 h of the onset of pain. The final extension of myocardial necrosis is reached within 2-4 h. An integrated programme has therefore been developed for the supervision and treatment of patients suffering acute coronary attack; it has been shown that it can markedly lower infarct mortality. It includes mobile prehospital care, intensive care treatment in the hospital, and rehabilitative procedures for application during reconvalescence. Early antiarrhythmic treatment and myocardial reperfusion via fibrinolysis are the main therapeutic procedures in the earliest stage. In hospital an operating room and an operating team must be available round the clock for the performance of coronary angiography followed by percutaneous transluminal coronary angioplasty or bypass surgery, which can be safely carried out in the acute stage provided the indications are strictly observed. Mortality and morbidity can be significantly lowered and both life expectancy and quality of life can be remarkably improved. (orig.) [de

Patients who suffer re-infarction during initial hospitalization for ST-elevation myocardial infarction (STEMI) have decreased survival compared to patients without re-infarction, so treatment of re-infarction may influence survival. To determine whether the utilization of reperfusion therapies varied within 12 h of re-infarction and was associated with 30-day mortality, we studied 552 patients with re-infarction of 17,073 patients with STEMI enrolled in HERO-2 in five regions (Russia, Eastern Europe, Western Countries, Asia, and Latin America). Patients presenting within 6 h of symptom-onset were randomized to receive either bivalirudin or unfractionated heparin intravenously just prior to streptokinase. Re-infarction occurred in 2.8 and 3.6% of bivalirudin and heparin treated patients, respectively (P = 0.004), but treatment assignment did not influence mortality after re-infarction. Patients with re-infarction had a higher 30-day mortality than those without re-infarction (24 vs. 10%; P model). Within 12 h of re-infarction, fibrinolytic therapy was administered to 12.0 and 8.2% underwent percutaneous coronary intervention (PCI); these two treatments were more frequently utilized in patients from Western countries (n = 112), compared to patients from other countries (n = 440) (34.8 and 16.1% compared to 6.1 and 6.1%, respectively, P < 0.001). Mortality was 15% in patients receiving reperfusion therapy for re-infarction and 27% for those with conservative management, hazard ratio (HR) 0.53 (95% CI 0.32-0.88), P = 0.01. In multiple Cox regression analysis which included adjustment for clinical variables and randomized treatment assignment, 30-day mortality after re-infarction varied by region (highest Latin America 29%, lowest Western countries 15%; P = 0.01). Other independent prognostic factors included age, time from randomization to re-infarction, and Killip class at randomization. The HR for PCI treatment of re-infarction was 0.18 [(95% CI 0.04-0.76), P = 0

To assess the degree of collateral vessels after myocardial infarction, coronary angiograms, left ventriculograms, and exercise thallium-201 myocardial scintigrams of 36 patients with previous myocardial infarction were reviewed. All 36 patients had total occlusion of infarct-related coronary artery and no more than 70% stenosis in other coronary arteries. In 19 of 36 patients with transient reduction of thallium-201 uptake in the infarcted area during exercise (Group A), good collaterals were observed in 10 patients, intermediate collaterals in 7 patients, and poor collaterals in 2 patients. In 17 of 36 patients without transient reduction of thallium-201 uptake in the infarcted area during exercise (Group B), good collaterals were seen in 2 patients, intermediate collaterals in 7 patients, and poor collaterals in 8 patients (p less than 0.025). Left ventricular contractions in the infarcted area were normal or hypokinetic in 10 patients and akinetic or dyskinetic in 9 patients in Group A. In Group B, 1 patient had hypokinetic contraction and 16 patients had akinetic or dyskinetic contraction (p less than 0.005). Thus, patients with transient reduction of thallium-201 uptake in the infarcted area during exercise had well developed collaterals and preserved left ventricular contraction, compared to those in patients without transient reduction of thallium-201 uptake in the infarcted area during exercise. These results suggest that the presence of viable myocardium in the infarcted area might be related to the degree of collateral vessels

Lesions of the thalamus and those extending into midbrain can cause various types of movement disorders such as dystonia, asterixis and ballism-chorea. Seizures are rare manifestation of thalamic disorder. Occurrence of seizures in bilateral thalamic infarct has been reported; but seizures in unilateral thalamic infarct have been reported very rarely. Literature review showed only single case of perinatal unilateral thalamic infarct presenting with seizures. We are reporting a unique case of convulsive seizure at the onset of unilateral thalamic infarct in an adult male, which has never been reported to the best of our knowledge.

Oxygen in the Setting of Acute Myocardial Infarction: Is It Really a Breath of Fresh Air?

Supplemental oxygen has been used in the setting of acute myocardial infarction (AMI). Once an official recommendation in the guidelines for the management of acute ST-segment elevation myocardial infarction, it is now mentioned as an intervention to be considered. Data for the use of supplemental oxygen or AMI are limited, and some data have suggested associated harm. We performed a systematic review of the literature and a subsequent meta-analysis of the data to determine the effect of high concentration oxygen versus titrated oxygen or room air in the setting of AMI. The following end points were studied: in-hospital mortality, opiate use, percentage of infarcted myocardium by magnetic resonance imaging (MRI), and mass of infarcted myocardium by MRI. No significant difference was noted with end points when comparing those randomized to high-concentration oxygen versus those randomized to titrated oxygen or room air in the setting of AMI. No significant publication bias was identified although this could not be assessed for all end points. High-concentration oxygen may not offer any benefit when compared to titrated oxygen or room air. A large, randomized trial is warranted to further delineate these differences with respect to multiple end points. © The Author(s) 2015.

Splenic infarction is a rare complication of infectious mononucleosis. We describe 3 cases of splenic infarction attributed to infectious mononucleosis that we encountered within a 2-month period. We underscore the awareness of this potential complication of infectious mononucleosis and discuss the differential diagnosis of splenic infarction, including infectious etiologies. While symptomatic management is usually sufficient for infectious mononucleosis-associated splenic infarction, close monitoring for other complications, including splenic rupture, is mandated.

Is there an association between depression and cardiovascular mortality or sudden death?

Science.gov (United States)

Alboni, Paolo; Favaron, Elisa; Paparella, Nelly; Sciammarella, Massimo; Pedaci, Mario

2008-04-01

The results of many studies and recent meta-analyses strongly suggest that depression is a risk factor for total and cardiovascular mortality, both in the general population and in patients with known heart disease. By contrast, the association between depression and sudden death or cardiac arrest has received little attention. This issue has been investigated in three recent studies; two were carried out in the general population and showed depression to be a independent risk factor for sudden death. The other study was carried out in patients with acute myocardial infarction (AMI); the adjusted relative risk (RR) of sudden death was significantly increased in depressed patients but, after adjustment for dyspnea/fatigue (a common symptom for heart disease and depression), the RR was no longer statistically significant. However, when the cognitive-affective depressive symptoms were examined separately from the somatic ones (dyspnea/fatigue, etc.), there was a clear trend for an association between cognitive-affective symptoms and sudden death. Because a risk factor can be defined as 'independent' only in a multivariate analysis in which variables are dichotomized, the presence of common symptoms between heart disease and depression represents a very difficult problem. However, taken together, the results of studies carried out in the general population and in patients with AMI strongly suggest that depression is a significant risk factor for sudden death.

1987-01-01

One hundred and five patients with cerebral infarction were studied by nuclear magnetic resonance (NMR) CT (resistive type of magnet with strength of 0.1 tesla) and X-ray CT. Pulse sequences used saturation recovery (Tr = 600 mSec), Inversion recovery (Tr = 500 mSec, Td = 300 mSec) and spin echo (Tr = 1500 mSec, Te = 40, 80, 120, 160 mSec). Fifteen cases were examined by NMR-CT within 24 hours from onset. Proton NMR imaging could not detect cerebral ischemia as early as 2 hours after onset, but except could detect the lesions in Se image the area of cerebral infarct 3 hours after onset. After 5 hours from onset image changes in SE were evident and corresponded to the area of cerebral infarct, but image changes in IR could not fully delineate the infarcted area. NMR images of 41 year-old woman with cerebral embolism by MCA trunck occlusion associated with mitral stenosis were presented, and NMR-CT was examined 10 hours, 9th and 43th days after episode of MCA occlusion. Sixty patents (64 times) with lacunar infarction were studied by NMR-CT and X-ray CT. The inversion recovery images were used mainly for detection of lesions and comparison with X-ray CT. In 160 lesions which were detected by NMR-CT or X-ray CT, could 156 lesions be detected by NMR-CT and 78 lesions by X-ray CT. Inversion recovery images were more useful for detection of lacunes than X-ray CT. Calculated T1 and T2 values prolonged with time course from onset. (author)

Acute myocardial infarct imaging with indium-111-labeled monoclonal antimyosin Fab

1987-01-01

Indium-111 monoclonal antimyosin Fab scintigraphy was used to detect myocardial necrosis in 52 of 54 patients (96.3%) with acute myocardial infarction. Infarcts were visualized when coronary arteries were persistently occluded (n = 10), became patent after thrombolysis (n = 33), or became patent after spontaneous reperfusion (n = 7). Posteroinferolateral visualizations were obtained in two patients with clinical and enzymatic evidence of infarction but normal electrocardiograms. Of the two patients in whom no infarcts were visualized, one had an anterior myocardial infarct. This patient underwent successful thrombolytic therapy, with attendant minimization of creatine kinase release. The other patient had a small, nonreperfused inferior myocardial infarct. Five patients with a history of remote infarction and acute necrosis showed antimyosin uptake only in regions concordant with the acute episodes of infarction, and radiolabeled antimyosin Fab localized in neither old infarcts nor normal, noninfarcted myocardium. Antimyosin Fab scintigraphy, thus, appears to be a highly specific means of delineating necrotic myocardium, at least in this limited and selected group of patients

Elevated serum uric acid (eSUA) was associated with unfavorable outcome in patients with ST-segment elevation myocardial infarction (STEMI). However, the effect of eSUA on myocardial reperfusion injury and infarct size has been poorly investigated. Our aim was to correlate eSUA with infarct size, infarct size shrinkage, myocardial reperfusion grade and long-term mortality in STEMI patients undergoing primary percutaneous coronary intervention. We performed a post-hoc patients-level analysis of two randomized controlled trials, testing strategies for myocardial ischemia/reperfusion injury protection. Each patient underwent acute (3-5 days) and follow-up (4-6 months) cardiac magnetic resonance. Infarct size and infarct size shrinkage were outcomes of interest. We assessed T2-weighted edema, myocardial blush grade (MBG), corrected Thrombolysis in myocardial infarction Frame Count, ST-segment resolution and long-term all-cause mortality. A total of 101 (86.1% anterior) STEMI patients were included; eSUA was found in 16 (15.8%) patients. Infarct size was larger in eSUA compared with non-eSUA patients (42.3 ± 22 vs. 29.1 ± 15 ml, P = 0.008). After adjusting for covariates, infarct size was 10.3 ml (95% confidence interval 1.2-19.3 ml, P = 0.001) larger in eSUA. Among patients with anterior myocardial infarction the difference in delayed enhancement between groups was maintained (respectively, 42.3 ± 22.4 vs. 29.9 ± 15.4 ml, P = 0.015). Infarct size shrinkage was similar between the groups. Compared with non-eSUA, eSUA patients had larger T2-weighted edema (53.8 vs. 41.2 ml, P = 0.031) and less favorable MBG (MBG < 2: 44.4 vs. 13.6%, P = 0.045). Corrected Thrombolysis in myocardial infarction Frame Count and ST-segment resolution did not significantly differ between the groups. At a median follow-up of 7.3 years, all-cause mortality was higher in the eSUA group (18.8 vs. 2.4%, P = 0.028). eSUA may affect myocardial

Myocardial imaging using beta-methyl-p-(123I)-iodophenylpentadecanoic acid (BMIPP) was performed in 11 patients with acute myocardial infarction. The left ventricular images were divided into 12 segments, and myocardial imagings with BMIPP were compared with coronary angiography (CAG), thallium-201 myocardial scintigraphy (TL) and wall motion obtained by two-dimensional echocardiography (WM). When the culprit lesion was at the proximal point of the left anterior descending artery (LAD), all segments showed depressed uptake. In 3 cases with single vessel disease of the LAD, inferior wall of the basis showed reduced uptake of BMIPP despite the location of the culprit lesion. In cases with discordant uptake between the two tracers, BMIPP frequently showed more severely depressed uptake than TL in the subacute phase, although the uptake of BMIPP correlated with that of TL (tau = 0.82, p less than 0.001). In such cases, the discordance was related to the improvement in WM from the acute phase to the convalescent phase. BMIPP uptake correlated with WM in the subacute phase (tau = 0.50, p less than 0.001). BMIPP showed more severely depressed uptake while WM showed mild asynergy in most cases in which discordance was found between the BMIPP and WM findings. However, there was no correlation between the change in WM from the acute to subacute phases, or the uptakes of BMIPP and TL alone. We concluded that the myocardial condition can be evaluated in detail in acute myocardial infarction by comparing the findings of BMIPP with those of TL and WM.

Acute myocardial infarction

Inflammatory processes after myocardial infarction have gained major interest in recent cardiovascular research. It is believed that not only the degree of cell recruitment to the heart plays a pivotal role in the quality of wound healing after myocardial infarction, but also the balance between different types or even subtypes of cells. It is also this balance which is thought to control key processes in tissue repair, such as apoptosis and neoangiogenesis. In this paper, we aim to review imaging strategies (with a special focus on nuclear molecular imaging strategies) that target cells and processes involved in postischemic inflammation and that have a high potential to be translated into clinic or that are already being used and evaluated in humans.

PET has some disadvantage in the imaging of small animal due to poor resolution. With the advance of microPET scanner, it is possible to image small animals. However, the image quality was not so much satisfactory as human image. As cats have relatively large sized brain, cat brain imaging was superior to mice or rat. In this study, we established the cat brain infarction model and evaluate it and its temporal change using microPET scanner. Two adult male cats were used. Anesthesia was done with xylazine and ketamine HCl. A burr hole was made at 1cm right lateral to the bregma. Collagenase type IV 10 ul was injected using 30G needle for 5 minutes to establish the infarction model. F-18 FDG microPET (Concorde Microsystems Inc., Knoxville. TN) scans were performed 1. 11 and 32 days after the infarction. In addition. 18F-FDG PET scans were performed using Gemini PET scanner (Philips medical systems. CA, USA) 13 and 47 days after the infarction. Two cat brain infarction models were established. The glucose metabolism of an infraction lesion improved with time. An infarction lesion was also distinguishable in the Gemini PET scan. We successfully established the cat brain infarction model and evaluated the infarcted lesion and its temporal change using F-18 FDG microPET scanner.

The purpose of this study was to examine the influence of coronary collateral circulation, which grows after acute myocardial infarction (MI), on infarct size and prognosis. Study subjects were 47 patients who had arteriographic evidence of 99-100% constricture of the infarct-related artery approximately one month after the onset of the first MI. Coronary collateral circulation was analyzed by a four-point scoring (grade 0-3). Furthermore, the patients underwent thallium-201 myocardial imaging one month and two years after the onset to evaluate infarct size. Infarct size was analyzed using extent score (ES) and severity score (SS). ES tended to be decreased during chronic MI stage. Coronary collateral circulation was judged as grade 1 (n=9), grade 2 (n=12), and grade 3 (n=26). There was no difference in infarct size among the three groups. In groups of grades 1 and 2, there was no difference in ES and SS between acute and chronic MI stages. In the group of grade 3, however, ES decreased from 41% to 27% and SS decreased from 68% to 38%, showing remarkable decrease during chronic MI stage. Although coronary collateral circulation one month after the onset is not always responsible for infarct size during acute MI stage, it is considered rsponsible for inhibiting the remodeling of infarction through the long term process.

The DASS-21 is a public domain instrument that is commonly used to evaluate depression and anxiety in psychiatric and community populations; however, the factor structure of the measure has not previously been examined in oncologic settings. Given that the psychometric properties of measures of distress may be compromised in the context of symptoms related to cancer and its treatment, the present study evaluated the psychometric properties of the DASS-21 Depression and Anxiety scales in cancer patients ( n = 376) as compared to noncancer control participants ( n = 207). Cancer patients ranged in age from 21 to 84 years (mean = 58.3, standard deviation = 10.4) and noncancer control participants ranged in age from 18 to 81 years (mean = 45.0, standard deviation = 11.7). Multiple group confirmatory factor analysis supported the structural invariance of the DASS-21 Depression and Anxiety scales across groups; the factor variance/covariance invariance model was the best fit to the data. Cronbach's coefficient alpha values demonstrated acceptable internal consistency reliability across the total sample as well as within subgroups of cancer patients and noncancer control participants. Expected relationships of DASS-21 Depression and Anxiety scale scores to measures of suicidal ideation, quality of life, self-rated health, and depressed mood supported construct validity. These results support the psychometric properties of the DASS-21 Depression and Anxiety scales when measuring psychological distress in cancer patients.

To determine the risk of hospitalization and death in relation to preexisting depression and anxiety among patients with cardiovascular disease (CVD). The cohort consisted of 799 Olmsted County, MN, residents diagnosed with CVD (myocardial infarction or heart failure) from January 1, 1979, to December 31, 2009, who completed a Minnesota Multiphasic Personality Inventory (MMPI) prior to their event. The MMPI was used to identify depression and anxiety, and participants were followed up for hospitalizations and death during an average of 6.2 years. Depression and anxiety were identified in 282 (35%) and 210 (26%) participants, respectively. After adjustment, depression and anxiety were independently associated with a 28% (95% confidence interval [CI], 8%-51%) and 26% (95% CI, 3%-53%) increased risk of being hospitalized, respectively. Depression also conferred an increased risk of all-cause mortality of similar magnitude, whereas the hazard ratio for anxiety was not statistically significant. The combined occurrence of depression and anxiety led to a 35% (95% CI, 8%-71%) increase in the risk of hospitalizations. Among patients with CVD, both preexisting depression and anxiety, occurring on average 17 years before the CVD event, independently predict hospitalizations. In addition, the 2 conditions may act synergistically on increasing health care utilization in patients with CVD.

The objectives of this study were to determine the incidence of a myocardial infarction "false alarm" and evaluate the efficacy of the initial electrocardiogram and cardiac enzymes in diagnosing myocardial infarction in Malaysia. We recruited patients who were admitted with suspected myocardial infarction from June to August 2008. The medical records of these patients were reviewed for the initial electrocardiogram, initial cardiac enzyme levels (creatinine kinase-MB and troponin T), and the final diagnosis upon discharge. The subjects were stratified into 2 groups: true myocardial infarction, and false alarm. 125 patients were enrolled in this study. Following admission and further evaluation, the diagnosis was revised from myocardial infarction to other medical conditions in 48 (38.4%) patients. The sensitivity and specificity of the initial ischemic electrocardiographic changes were 54.5% and 70.8%, respectively. Raised cardiac enzymes had a sensitivity of 44.3% and specificity of 95.8%. A significant proportion of patients in Malaysia are admitted with a false-alarm myocardial infarction. The efficacy of the electrocardiogram in diagnosing myocardial infarction in Malaysia was comparable to the findings of Western studies, but the cardiac enzymes had a much lower sensitivity.

We conducted a clinical study of 155 cases that were confirmed to have brainstem infarctions on MRI (T[sub 1]-weighted image showed a low signal and T[sub 2]-weighted image showed a high signal, measuring in excess of 2 x 2 mm). The majority of the brainstem infarction was located in the pontine base in 132 cases (85.2%). Of these, 19 cases had double lesions including infarctions in the pontine base. Second infarctions frequently occurred in the cerebral peduncle or medical medulla oblongata, unilateral to the pontine infarctions. In addition to 98 symptomatic cases, there were 57 cases of 'asymptomatic' brainstem infarction. They comprised 24 cases accompanying other symptomatic cerebrovascular diseases in the supratentorium and 33 cases of transient subjective complaints such as headache or vertigo-dizziness. Complication by supratentorial infarctions was significantly frequent in cases of brainstem infarction (p<0.001), 122 of 155 cases (78.7%), especially in the pontine base (88.6%); while in the control cases (without brainstem infarction) only 65 of 221 cases (29.4%). These findings are considered to show the widespread progress of arteriosclerosis in brainstem infarction, especially in ones in the pontine base. (author).

Previous studies explored the association between hemorheological alterations and acute myocardial infarction, pointing out the role of hematological components on microvascular flow. The aim of this study was to evaluate the association between blood viscosity and infarct size, estimated by creatine kinase (CK) peak activity and cardiac Troponin I (cTnI) peak concentration in ST-segment elevation myocardial infarction (STEMI) patients after primary percutaneous coronary intervention (PCI). The study population included 197 patients with diagnosis of STEMI undergoing PCI. Hemorheological studies were performed by assessing whole blood viscosity (measured at shear rates of 0.512 s(-1) and 94.5 s(-1)) and plasma viscosity using the Rotational Viscosimeter LS 30 and erythrocyte deformability index by Myrenne filtrometer. Significant correlations between CK peak activity, cTnI peak concentration, left ventricular ejection fraction and hemorheological variables were observed. At linear regression analysis (adjusted for age, gender, traditional cardiovascular risk factors, renal dysfunction, timeliness of reperfusion, pre-PCI TIMI flow, infarct location, multivessel disease and previous coronary artery disease) leukocytes and whole blood viscosity at 0.512 s(-1) and 94.5 s(-1) were independently and positively associated with infarct size. These results demonstrate a significant and independent association between hemorheology and infarct size in STEMI patients after PCI suggesting that blood viscosity, in a condition of low flow, might worsen myocardial perfusion leading to an increased infarct size. The measurement of whole blood viscosity in STEMI patients could help to identify those who may benefit from new therapeutic strategies.

To understand the pathophysiology of ischemic stroke, in vivo imaging of the brain tissue viability and related spreading depolarization is crucial. In the infarct core, impairment of energy metabolism causes anoxic depolarization (AD), which considerably increases energy consumption, accelerating irreversible neuronal damage. In the peri-infarct penumbra region, where tissue is still reversible despite limited blood flow, peri-infarct depolarization (PID) occurs, exacerbating energy deficit and hence expanding the infarct area. We previously showed that light-scattering signal, which is sensitive to cellular/subcellular structural integrity, was correlated with AD and brain tissue viability in a rat hypoxia-reoxygenation model. In the present study, we performed transcranial NIR diffuse reflectance imaging of the rat brain during middle cerebral artery (MCA) occlusion and examined whether the infarct core and PIDs can be detected. Immediately after occluding the left MCA, light scattering started to increase focally in the occlusion site and a bright region was generated near the occlusion site and spread over the left entire cortex, which was followed by a dark region, showing the occurrence of PID. The PID was generated repetitively and the number of times of occurrence in a rat ranged from four to ten within 1 hour after occlusion (n=4). The scattering increase in the occlusion site was irreversible and the area with increased scattering expanded with increasing the number of PIDs, indicating an expansion of the infarct core. These results suggest the usefulness of NIR diffuse reflectance signal to visualize spatiotemporal changes in the infarct area and PIDs.

Full Text Available Early and correct diagnostics of myocardial infarction in newborns is impossible without modern instrumental methods, among which echocardiography is the leading one. Hypokinesia, akinesia or dyskinesia of local segments of the heart ventricular wall is determined with echocardiography. We examined a 3-days-old baby with circulatory failure requiring cardiotonic support. On auscultation there was a heart murmur. It was an intracardiac conduction disoder and infarction-like changes on ECG, however, a convincing evidence to interpret the patient’s condition as myocardial infarction has not been received. Therefore, it was decided to conduct echocardiography. According to the results of echocardiography the presence of hyperechogenic diskinetic locus in the apical segment of the right ventricle (post-infarction scar, a local pericardial effusion in the same projection, hyperechogenic movable mass (thrombus in the apical segment of the right ventricle were determined that together with the results of the ECG allowed us to set diagnosis myocardial infarction. Transthoracic echocardiography is one of highly informative methods; the data obtained allowed to correctly interpret the clinical picture of heart failure and to reveal the cause of the patien’st dependance on cardiotonic support.

Proton nuclear magnetic resonance (NMR) images depict the distribution and concentration of mobile protons modified by the relaxation times T1 and T2. Using the steady-state-free-precession (SSFP) technique, serial coronal images were obtained sequentially over time in laboratory animals with experimental ischemic infarction. Image changes were evident as early as 2 hours after carotid artery ligation, and corresponded to areas of ischemic infarction noted pathologically. Resulting SSFP images in experimental stroke are contrasted to inversion-recovery NMR images in an illustrative patient with established cerebral infarction. Bulk T1 and T2 measurements were made in vitro in three groups of gerbils: normal, those with clinical evidence of infarction, and those clinically normal after carotid ligature. Infarcted hemispheres had significantly prolonged T1 and T2 (1.47 +/- .12 sec, 76.0 +/- 9.0 msec, respectively) when compared to the contralateral hemisphere (T1 . 1.28 +/- .05 sec, T2 . 58.7 +/- 3.9 msec) or to the other two groups. These data suggest that changes in NMR parameters occur and can be detected by NMR imaging as early as two hours after carotid artery ligation

Isolated vertigo is generally attributed to labyrinthine disease, but may also signal otherwise asymptomatic cerebellar infarction. Of 309 subjects admitted between April 2004 and March 2009 for the single symptom of acute vertigo initially thought to be labyrinthine, four were found to have cerebellar infarction of the posterior inferior cerebellar artery area (PICA). All were over 60 years old and had risk factors including hypertension, diabetes mellitus, arrhythmia, and/or hyperlipidemia. Two had trunk ataxia, with magnetic resonance imaging (MRI) showing infarction within a few days. The other two could walk without apparent trunk ataxia, however, it took 4 to 7 days to find the infarction, mainly through neurological, neurootological, and MRI findings. Neurologically, astasia, dysbasia or trunk ataxia were important signs. Neurootologically, nystagmus and electronystagmographic testing involving eye tracking, saccade, and optokinetic patttens were useful.

Single photon-emission tomography (SPECT) and indium 111-labeled monoclonal antimyosin Fab fragments were used to measure myocardial infarct size in 12 dogs, six subjected to balloon catheter-induced coronary artery occlusion for 6 hr (late reperfusion) and six subjected to occlusion with reperfusion at 2 hr (early reperfusion). Tomographic imaging was performed 24 hr after the intravenous injection of labeled Fab fragments with the use of a dual-head SPECT camera with medium-energy collimators. Immediately after the first tomographic scan, thallium-201 was injected into nine of 12 dogs and imaging was repeated. Estimated infarct size in grams was calculated from transaxially reconstructed, normalized, and background-corrected indium SPECT images with the use of a threshold technique for edge detection. Estimated noninfarcted myocardium in grams was calculated from obliquely reconstructed thallium SPECT images by a similar method. The animals were killed and infarct size in grams and true infarct size as a percentage of total left ventricular myocardial volume were measured by triphenyl tetrazolium chloride staining. Estimated infarct size from indium SPECT images showed an excellent correlation with true infarct size (r = .95, SEE = 4.1 g). Estimated percentage myocardium infarcted was calculated by dividing estimated infarct size from indium images by the sum of estimated infarct size plus estimated noninfarcted myocardium obtained from thallium images. Correlation between the estimated percentage of myocardium infarcted and true percentage of myocardium infarcted was excellent

Aphasia following infarction of Wernicke's area typically resolves to some extent over time. The nature of this recovery process and its time course have not been characterized in detail, especially in the acute/subacute period. The goal of this study was to document recovery after infarction of Wernicke's area in detail in the first 3 months after stroke. Specifically, we aimed to address two questions about language recovery. First, which impaired language domains improve over time, and which do not? Second, what is the time course of recovery? We used quantitative analysis of connected speech and a brief aphasia battery to document language recovery in two individuals with aphasia following infarction of the posterior superior temporal gyrus. Speech samples were acquired daily between 2 and 16 days post stroke, and also at 1 month and 3 months. Speech samples were transcribed and coded using the CHAT system, in order to quantify multiple language domains. A brief aphasia battery was also administered at a subset of five time points during the 3 months. Both patients showed substantial recovery of language function over this time period. Most, but not all, language domains showed improvements, including fluency, lexical access, phonological retrieval and encoding, and syntactic complexity. The time course of recovery was logarithmic, with the greatest gains taking place early in the course of recovery. There is considerable potential for amelioration of language deficits when damage is relatively circumscribed to the posterior superior temporal gyrus. Quantitative analysis of connected speech samples proved to be an effective, albeit time-consuming, approach to tracking day-by-day recovery in the acute/subacute post-stroke period.

The distribution of cerebral ischemic infarction and stenosis in ischemic stroke may vary with age-group, race and gender. This study was conducted to understand the risk factors and characteristics of cerebral infarction and stenosis of vessels in young Chinese patients with ischemic stroke. This was a retrospective study, from January 2007 to July 2012, of 123 patients ≤50 years diagnosed with acute ischemic stroke. Patient characteristics were compared according to sex (98 males and 25 females) and age group (51 patients were ≤45 years and 72 patients were 46-50 years). Characteristics of acute ischemic infarction were studied by diffusion weighted imaging. Stenosis of intra- and extracranial arteries was diagnosed by duplex sonography, head magnetic resonance angiography (MRA) or cervical MRA. Common risk factors were hypertension (72.4 %), dyslipidemia (55.3 %), smoking (54.4 %) and diabetes (33.3 %). Lacunar Infarction was most common in our patients (41.5 %). Partial anterior circulation infarction was predominant in females (52.0 vs 32.7 %; P = 0.073) and posterior circulation infarction in males (19.8 vs 4 %; P = 0.073). Multiple brain infarctions were found in 38 patients (30.9 %). Small artery atherosclerosis was found in 54 patients (43.9 %), with higher prevalence in patients of the 46-50 years age-group. Intracranial stenosis was more common than extracranial stenosis, and middle cerebral artery stenosis was most prevalent (27.3 %). Stenosis in the anterior circulation was more frequent than in the posterior circulation (P young patients, hypertension, smoking, dyslipidemia and diabetes were common risk factors. Intracranial stenosis was most common. The middle cerebral artery was highly vulnerable.

Full Text Available Primary omental infarction (POI has a low incidence worldwide, with most cases occurring in adults. This condition is rarely considered in the differential diagnosis of acute abdominal pain in childhood. Herein, we present a case of omental infarction in an obese 10-year-old boy who presented with acute abdominal pain in the right lower abdomen. The ultrasound (US examination did not reveal the appendix but showed secondary signs suggesting acute appendicitis. The child was thus operated on under the preoperative diagnosis of acute appendicitis but the intraoperative finding was omental infarct. Since the omental infarct as etiology of acute abdominal pain is uncommon, we highlight some of the possible etiologies and emphasize the importance of accurate diagnosis and appropriate treatment of omental infarction.

Testosterone and Depression

Full Text Available Androgens have various effects on human body and mood. Testosterone, a hormone mainly secreted from testes and adrenals, is one of the most potent androgens. Multiple studies have found that testosterone plays a role in regulating sexual activity, libido, social behaviors, aggression, cognitive functions, sleep control and well-being in men and women. Testosterone deficiency in hypogonadic or elderly men leads to neuropsychiatric problems, such as fatigue, loss of libido, irritability, insomnia and depressive mood. Testosterone replacement therapy consistently reverses these sequel in men. On the other hand, hyperandrogenic states in women are related to aggression and antisocial behavior, which might lead to depressive mood. Low testosterone levels may also result in depression among oophorectomized women. Because of such effects, a relationship between testosterone and depression has long been an issue of speculation, but yet very few studies have addressed this relation. Along with clinical studies, experimental and epidemiological studies show that testosterone is related to depression in men and women. But studies of testosterone concentrations in depression have yielded inconsistent results reporting low as well as high testosterone levels associated with depression. In this article, the physiological and psychological effects of testosterone and evidence regarding its relationship to depressive disorders and possible gender differences have been reviewed.

2004-01-01

Pathological laughter is an uncommon symptom usually caused by bilateral, diffuse cerebral lesions. It has rarely been reported in association with isolated cerebral lesions. Midbrain involvement causing pathological laughter is extremely unusual. We describe three patients who developed pathological laughter after midbrain and pontine-midbrain infarction. In two patients a small infarction in the left paramedian midbrain was detected, whereas the third one sustained a massive bilateral pontine infarction extending to the midbrain. Laughter heralded stroke by one day in one patient and occurred as a delayed phenomenon three months after stroke in another. Pathological laughter ceased within a few days in two patients and was still present at a two year follow-up in the patient with delayed-onset laughter. Pathological laughter can herald midbrain infarction or follow stroke either shortly after onset of symptoms or as a delayed phenomenon. Furthermore, small unilateral midbrain infarctions can cause this rare complication. PMID:15706050

Acute myocardial infarctions were produced in nine dogs by ligation of the left anterior descending coronary artery. Twenty-four hours after ligation, 0.5 mM/kg of gadolinium (Gd)-DTPA was injected intravenously, followed by cardiectomy 30 min later. Indium-111 antimyosin was administered intravenously 6 hr before cardiectomy to compare the infarct size with Gd-DTPA contrast enhancement. Areas of Gd-DTPA contrast enhancement were closely correlated with those of indium-111 antimyosin uptake (r = .86), although the former showed slightly greater than the latter. Partial and complete enhancements were observed in three and six dogs, respectively. In the T1 and T2 maps, T1 relaxation times of the infarcted area showed greater T1 shortening compared with normal myocardium, whereas T2 relaxation times were not different between infarcted and normal myocardium. Thus, Gd-DTPA showed significant contrast enhancement of the infarcted area because of greater T1 shortening and the extent of Gd-DTPA contrast enhancement expressed the infarct size precisely

Full Text Available Postmyocardial infarction ventricular septal defect is an increasingly rare mechanical complication of acute myocardial infarction. We present a case of acute myocardial infarction from right coronary artery occlusion that developed hypotension and systolic murmur 12 hours after successful percutaneous coronary intervention. Although preoperative imaging suggested a large ventricular septal defect and a pseudoaneurysm, intraoperative findings concluded a serpiginous dissection of the ventricular septum. The imaging technicalities are discussed.

Using magnetization transfer (MT) imaging, we studied the underlying pathological conditions of periventricular hyperintense (PVH) white matter changes seen on T2-weighted MR images of patients with multi-infarct dementia. Twenty-two patients with multiple lacunar infarcts and PVH lesions, including 11 with dementia (diagnosed as multi-infarct dementia) and 11 without dementia, and 10 control subjects (with multiple lacunes, but no PVH lesion) were studied using the MT technique. MT ratios (MTRs) were calculated for PVH lesions (normal-appearing frontal white matter in controls) and the genu of the corpus callosum. Signal intensities on T2-weighted images in PVH lesions of patients were significantly higher than those in normal-appearing white matter of controls, while there were no significant differences in signal intensity in the genu of the corpus callosum among the dementia, non-dementia and control groups. However, MTRs in patients with PVH lesions were significantly lower than those in controls, and MTRs in demented patients were significantly lower than those in non-demented patients. Moreover, MTRs in the genu of the corpus callosum of demented patients were significantly lower than in those in non-demented patients and controls. MTRs in PVH lesions and the genu of the corpus callosum significantly correlated with Hasegawa's dementia scale score. These results suggest that there is some difference in histopathologic changes of PVH lesions between demented and non-demented patients and that the pathological substrate in the corpus callosum may play a role in inducing cognitive decline. Studies with MT imaging may allow the characterization of different pathological conditions that cannot be visualized by conventional MRI. (author)

2011-01-01

This is a case of a 2-year-old boy with sickle cell disease who presented with bilateral eyelid swelling, limited extraocular motility, and lateral subperiosteal fluid collection associated with bilateral lateral orbital wall infarctions on MRI. The patient was managed medically with intravenous fluids, analgesics, broad-spectrum antibiotics, systemic steroids, and clinically improved. Patients with sickle cell disease are susceptible to infarction of the orbital bones during vaso-occlusive crises. Orbital wall infarction can lead to acute proptosis and restricted extraocular motility. Orbital wall infarction should be considered in sickle cell patients with orbital diseases so that appropriate treatment can be instituted promptly to prevent the serious sequelae of orbital compression syndrome.

Major depressive disorder (MDD) is an independent risk factor for coronary heart disease (CHD), and influences the occurrence and prognosis of cardiovascular events. Although there is evidence that antidepressants may be cardioprotective after acute myocardial infarction (AMI) comorbid with MDD, the operative pathophysiological mechanisms remain unclear. Our aim was therefore to explore the molecular mechanisms of escitalopram on myocardial apoptosis and the expression of Bax and Bcl-2 in a rat model of depression during myocardial ischemia/reperfusion (I/R). Rats were divided randomly into 3 groups (n = 8): D group (depression), DI/R group (depression with myocardial I/R) and escitalopram + DI/R group. The rats in all three groups underwent the same chronic mild stress and separation for 21 days, at the same time, in the escitalopram + DI/R group, rats were administered escitalopram by gavage (10 mg/kg/day). Ligation of the rat's left anterior descending branch was done in the myocardial I/R model. Following which behavioral tests were done. The size of the myocardial infarction was detected using 1.5% TTC dye. The Tunel method was used to detect apoptotic myocardial cells, and both the Rt-PCR method and immunohistochemical techniques were used to detect the expression of Bcl-2 and Bax. Compared with the D and DI/R groups, rats in Escitalopram + DI/R group showed significantly increased movements and sucrose consumption (P escitalopram + DI/R group was significantly decreased (P escitalopram + DI/R groups (P escitalopram + DI/R group were significantly decreased (P escitalopram + DI/R group (P escitalopram. This suggests that clinically escitalopram may have a direct cardioprotective after acute myocardial infarction.

Full Text Available Abstract Background A general internist has an important role in primary care, especially for the elderly in rural areas of Japan. Although effective intervention models for depressed patients in general practice and primary care settings have been developed in the US and UK medical systems, there is little information regarding even the recognition rate and prescription rate of psychotropic medication by general internists in Japan. The present study surveyed these data cross-sectionally in a general internal medicine outpatient clinic of a Japanese rural hospital. Methods Patients were consecutively recruited and evaluated for major depressive disorder or any mood disorder using the Patient Health Questionnaire (PHQ. Physicians who were blinded to the results of the PHQ were asked to diagnose whether the patients had any mental disorders, and if so, whether they had mood disorders or not. Data regarding prescription of psychotropic medicines were collected from medical records. Results Among 312 patients, 27 (8.7% and 52 (16.7% were identified with major depressive disorder and any mood disorder using the PHQ, respectively. Among those with major depressive disorder, 21 (77.8% were recognized by physicians as having a mental disorder, but only three (11.1% were diagnosed as having a mood disorder. Only two patients with major depressive disorder (7.4% had been prescribed antidepressants. Even among those (n = 15 whom physicians diagnosed with a mood disorder irrespective of the PHQ results, only four (26.7% were prescribed an antidepressant. Conclusions Despite a high prevalence of depression, physicians did not often recognize depression in patients. In addition, most patients who were diagnosed by physicians as having a mood disorder were not prescribed antidepressants. Multiple barriers to providing appropriate care for depressed patients exist, such as recognizing depression, prescribing appropriate medications, and appropriately referring

Full Text Available Background Lacunar syndrome not due to lacunar infarct is poorly characterised. This single centre, retrospective study was conducted to describe the clinical characteristics of patients with lacunar syndrome not due to lacunar infarct and to identify clinical predictors of this variant of lacunar stroke. Methods A total of 146 patients with lacunar syndrome not due to lacunar infarction were included in the "Sagrat Cor Hospital of Barcelona Stroke Registry" during a period of 19 years (1986-2004. Data from stroke patients are entered in the stroke registry following a standardized protocol with 161 items regarding demographics, risk factors, clinical features, laboratory and neuroimaging data, complications and outcome. The characteristics of these 146 patients with lacunar syndrome not due to lacunar infarct were compared with those of the 733 patients with lacunar infarction. Results Lacunar syndrome not due to lacunar infarct accounted for 16.6% (146/879 of all cases of lacunar stroke. Subtypes of lacunar syndromes included pure motor stroke in 63 patients, sensorimotor stroke in 51, pure sensory stroke in 14, atypical lacunar syndrome in 9, ataxic hemiparesis in 5 and dysarthria-clumsy hand in 4. Valvular heart disease, atrial fibrillation, sudden onset, limb weakness and sensory symptoms were significantly more frequent among patients with lacunar syndrome not due to lacunar infarct than in those with lacunar infarction, whereas diabetes was less frequent. In the multivariate analysis, atrial fibrillation (OR = 4.62, sensorimotor stroke (OR = 4.05, limb weakness (OR = 2.09, sudden onset (OR = 2.06 and age (OR = 0.96 were independent predictors of lacunar syndrome not due to lacunar infarct. Conclusions Although lacunar syndromes are highly suggestive of small deep cerebral infarctions, lacunar syndromes not due to lacunar infarcts are found in 16.6% of cases. The presence of sensorimotor stroke, limb weakness and sudden onset in a patient

Full Text Available At present, cardiovascular diseases are depicted to be the leading cause of death worldwide according to the World Health Organization. In the future, projections predict that ischemic heart disease will persist in the top main causes of illness. Within this alarming context, some tiny master regulators of gene expression programs, namely, microRNAs (miRNAs carry three promising potentials. In fact, miRNAs can prove to be useful not only in terms of biomarkers allowing heart injury detection but also in terms of therapeutics to overcome limitations of past strategies and treat the lesions. In a more creative approach, they can even be used in the area of human engineered cardiac tissues as maturation tools for cardiomyocytes (CMs derived from pluripotent stem cell. Very promising not only for patient-specific cell-based therapies but also to develop biomimetic microsystems for disease modeling and drug screening, these cells greatly contribute to personalized medicine. To get into the heart of the matter, the focus of this review lies primarily on miRNAs as acute myocardial infarction (AMI biomarkers. Only large cohort studies comprising over 100 individuals to reach a potent statistical value were considered. Certain miRNAs appeared to possibly complement protein-based biomarkers and classical risk factors. Some were even described to bear potential in the discrimination of similar symptomatic pathologies. However, differences between pre-analytical and analytical approaches substantially influenced miRNA data. Further supported by meta-analysis studies, this problem had to be addressed. A detailed critical analysis of each step to define miRNAs biomarker potential is provided to inspire a future improved universal strategy. Interestingly, a recurrent set of cardiomyocyte-enriched miRNAs was found, namely, miR-1; miR-133; miR-208a/b; and miR-499a. Each member of this myomiRs group displayed promising roles either individually or in combination

Objectives: The aim of this study was to determine the feasibility of multi-slice computed tomography (MSCT) biphasic imaging in assessing myocardial viability and infarct parameters in both acutely and chronically infarcted pig models. Materials and methods: Seven pigs underwent ligation of the distal left anterior descending artery. Imaging was performed on the day of infarction and 3 months post-infarct, with contrast infusion followed by MSCT scan acquisition at different time-points. Left ventricular ejection fractions (LVEFs) were obtained by left ventriculography (LVG) after 3 months. Infarcted locations found using MSCT were compared with those obtained using SPECT. Infarcted areas were also analysed histopathologically and compared with the findings from MSCT. Results: Chronic phase images had perfusion defects with lower CT values relative to normal myocardium (43 ± 10 HU vs. 156 ± 13 HU, p = 0.001) on the early images but no residual defects on delayed images. However, we found hyperenhancing regions on delayed images (244 ± 20 HU vs. 121 ± 25 HU, p = 0.001), and good correlation between MSCT- and LVG-derived LVEFs (60.56 ± 7.56%). The areas identified by MSCT corresponded to the location of 201 Tl SPECT-/pathologic staining-derived regions in all models. Infarct size was in good agreement with MSCT and pathological analyses of chronic phase models. Conclusions: Necrotic myocardium in different stages after infarction could be qualitatively and quantitatively assessed using MSCT biphasic imaging, as could the status of microcirculation formation. MSCT-measured LVEFs matched well with other modalities, and hence MSCT is a useful tool in assessing post-infarct cardiac function.

The purposes of this study were to investigate the mediating effect of smartphone addiction and depression on neuroticism and quality of life. Self-reported measures of neuroticism, smart-phone addiction, depression, and quality of life were administered to 722 Chinese university students. Results showed smartphone addiction and depression were both significantly affected neuroticism and quality of life. The direct effect of neuroticism on quality of life was significant, and the chain-mediating effect of smartphone addiction and depression was also significant. In conclusion, neuroticism, smartphone addiction, and depression are important variables that worsen quality of life. Copyright © 2017 Elsevier B.V. All rights reserved.

To report a phenomenon of optical nerve atrophy secondary to lateral occipital lobe infarction. Two successive patients with unilateral occipital lobe infarction who experienced bilateral optical nerve atrophy during the follow-up underwent cranial imaging, fundus photography, and campimetry. Each patient was diagnosed with occipital lobe infarction by cranial MRI. During the follow-up, a bilateral optic atrophy was revealed, and campimetry showed a right homonymous hemianopia of both eyes with concomitant macular division. Bilateral optic atrophy was related to occipital lobe infarction, and a possible explanation for the atrophy was transneuronal degeneration caused by occipital lobe infarction.

Cerebellar infarction is easily misdiagnosed or underdiagnosed. In this study, we investigated factors leading to misdiagnosis of cerebellar infarction in patients with acute ischemic stroke. Data on neurological and radiological findings from 114 consecutive patients with acute cerebellar infarction were analyzed. We investigated factors associated with misdiagnosis from the data on clinical findings. Thirty-two (28%) patients were misdiagnosed on admission. Misdiagnosis was significantly more frequent in patients below 60 years of age and in patients with vertebral artery dissection, and significantly less frequent in patients with dysarthria. It tended to be more frequent in patients with the medial branch of posterior inferior cerebellar artery territory infarction, and infrequent in patients with the medial branch of the superior cerebellar artery territory infarction. Thirty out of 32 (94%) misdiagnosed patients were seen by physicians that were not neurologists at the first visit. Twenty-four of 32 (75%) misdiagnosed patients were screened only by brain CT. However, patients were not checked by brain MRI or follow-up CT until their conditions worsened. Patients below 60 years of age and patients with vertebral artery dissection are more likely to have a cerebellar infarction misdiagnosed by physicians other than neurologists.

The Depressive Personality Disorder Inventory (DPDI; Huprich, Margrett, Barthelemy, & Fine, 1996; see Appendix) was created to assess Depressive Personality Disorder in clinical and nonclinical samples. Since its creation, the DPDI has been used in multiple studies, and the psychometric properties of the measure have generally supported its reliability, convergent validity, and construct validity; however, evidence for the measure's discriminant validity has been mixed. Specifically, the DPDI tends to correlate highly with measures of current depressive symptoms, which limits its efficacy in differentiating current depressive symptoms from a depressive personality structure. A principal components analysis of 362 individuals who completed both the DPDI and Beck Depression Inventory (BDI-II; Beck, Steer, & Brown, 1996) found that 49% of the variance was accounted for in two components. Seven items from the DPDI loaded more strongly on the first component composed of many BDI-II items. These items were removed in order to create a measure believed to assess DPD without the confounding influence of current depressive symptomology. Principal components analysis of the revised measure yielded three components, accounting for 46% of the variance. The revised DPDI was used to calculate convergent, discriminant, and construct validity coefficients from measures used in former studies. Virtually no improvement in the validity coefficients was observed. It is concluded that assessing DPD via self-report is limited in its utility.
