    Purpose. - To identify prognostic factors and treatment toxicity in a series of epidermoid cancers of the anal canal without evident metastasis. Patients and methods. - Between June 1972 and January 1997, 305 patients (pts) were treated with curative-intent radiation therapy (RT). The T-stages according to the 1987 UICC classification were: 26 T1, 141 T2, 104 T3, and 34 T4. There were 49 pts with nodal involvement at presentation. Pretreatment anal function scoring according to our in-house system was: 22 scored 0, 182 scored 1, 74 scored 2, 7 scored 3. 11 scored 4, and 9 not available pts. The treatment started with external beam RT (EBRT) in 303 pts (median dose: 45 Gy). After a rest period of 4 to 6 weeks, a boost of 20 Gy was delivered by EBRT in 279 pts and by interstitial {sup 192}Ir brachytherapy (Bcy) in 17 pts. Seven pts received only one course of EBRT (mean dose: 49.5 Gy) and 2 pts were treated with interstitial {sup 192}Ir Bcy alone (55 and 60 Gy, respectively). concomitant chemotherapy (5-fluoro-uracil and either mitomycin C or cisplatin) was delivered to 19 pts. Mean follow-up was 103 months. Results. - At the end of RT local tumor clinical complete response (cCR) rate was 80%. Out of 61 non responders or local progressive tumors 27 (44%) were salvaged with abdomino-perineal resection (APR). The rate of local tumor relapse (LR) was 12%. Out of 37 LTR, 20 (54%) were salvaged with APR and one with interstitial {sup 192}Ir Bcy. The overall local tumor control (LC) rate with or without salvage local treatment was 84%. LC rate with a good anal function scoring (score 0 and 1) was 56.5%0. Among 181/186 available pts who preserved their anus, 94% had a good anal function scoring. For a subgroup of 15 pts with length tumor <2 cm-N0, the LC rate after the end of RT was 100% the LC rate with or without local salvage treatment was 100%, and among 13 available pts who preserved their anus, the anal function scoring was good in 12 pts (92%).

    To identify prognostic actors and treatment toxicity in a series of operable endometrial adenocarcinomas. Between November 1971 and October 1992, 437 patients (pts) with endometrial carcinoma, staged according to the 1988 FIGO staging system, underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy without (n = 140) or with (n = 297) pelvic lymph node dissection. The chronology of RT was not randomized and depended on the usual practices of the surgical teams. Group I: 79 pts received preoperative utero-vaginal brachytherapy (mean total dose [MD]: 57 Gy). Group II: 358 pts received postoperative RT (196 pts received vaginal brachytherapy alone [MD: 50 Gy], 158 pts had external beam pelvis RT [EPRT] [MD: 46 Gy over 5 weeks] followed by vaginal brachytherapy [MD: 17 Gy], and 4 pts had EPRT alone [MD: 46 Gy over 5 weeks]). The mean follow-up was 128 months. The 10-year disease-free survival rate was 86%. From 57 recurrences, 12 were isolated loco-regionally. Multivariate analysis showed that independent factors decreasing the probability of disease-free survival were: histologic type (clear cell carcinoma, p = 0.038), largest histologic tumor diameter > 3 cm (p = 0.015), histologic grade (p = 0.008), myometrial invasion > 1/2 (p 0.0055), and 1988 FIGO staging system (p= 9.10{sup -8}). In group II, the addition of EPRT did not seem to improve locoregional control. The postoperative complication rate was 7%. The independent factors increasing the risk of postoperative complications were FIGO stage (p = 0.02) and pelvic lymph node dissection (p = 0.011). The 10-year rate for grade 3 and 4 late radiation complications according to the LENT-SOMA scoring system was 3.1 %. EPRT independently increased the 10-year rate for grade 3 and 4 late radiation complications (R.R.: 5.6, p = 0.0096). EPRT increases the risk of late radiation complications.

    Full Text Available Purpose: It has been known that psychological factors have an important effect on the decision to undergo aesthetic surgery. In this study, we aimed to test the hypothesis that the personality traits of people admitted for aesthetic surgery differ from those of people who have never planned to undergo aesthetic surgery in their lives. Material and Methods: Forty-seven patients who were referred to the outpatient clinic of the Faculty of Medicine, Department of Plastic, Reconstructive, and Aesthetic Surgery, Kirikkale University to undergo aesthetic surgery were enrolled in the study. Forty-three subjects who neither underwent nor planned to undergo aesthetic surgery at any time in their lives were included in the study as a control group. Psychometric evaluation of the patients and the control group was conducted using the Turkish version of the Minnesota Multiphasic Personality Inventory (MMPI. Results: Taking 65 as a cut-off point, the ratio of patients who scored and #8805;65 on the hysteria subscale of the MMPI was found to be significantly higher in the sugery group than in the control group and the ratio on social introversion subscale was also higher in the patient group than in the control group, very closely approaching significance. Conclusion: It should be kept in mind that people who have personality traits that can be partially improved with psyachiatric treatment, such as social introverted, lonely, timid, shy, and hysterical and feel the need for validation by others, may be more often admitted for aesthetic surgery.

    The urokinase-type plasminogen activator receptor (uPAR) has important functions in cell migration. uPAR can be shed from the cell membrane resulting in soluble uPAR (suPAR). Further cleavage gives rise to shorter fragments with largely unknown functions. Recent studies have demonstrated that both overexpression of uPAR on podocytes and the administration of suPAR cause proteinuria in mice. The common pathogenic mechanism involves the activation of podocyte β3-integrin. Increased activation of β3-integrin is also observed in patients with focal and segmental glomerulosclerosis (FSGS). These observations form the basis for the hypothesis that suPAR may be the circulating factor causing FSGS. A recent study fosters this idea by demonstrating increased suPAR levels in the serum of patients with FSGS and reporting an association with recurrence after transplantation and response to plasmapheresis. However, this study was heavily biased, and subsequent studies have given conflicting results. Although the experimental work is very suggestive, at present there is no proof that any known human suPAR fragment causes FSGS in humans. We therefore suggest that the measurement of suPAR using currently available assays has absolutely no value at the present time in decision-making in routine clinical practice.

    Panic disorder (PD) is often correlated with high neuroticism and low extraversion. This study aims to ascertain whether PD patients differ from healthy controls in regard to personality traits and determine if these traits are correlated with comorbid disorders, anxiety, and depression symptoms. Personality traits of 69 PD patients and 42 controls were compared using the Maudsley Personality Inventory. In PD patients, comorbidities, anxiety, and depression symptoms were also evaluated. PD patients showed higher neuroticism and lower extraversion compared with healthy controls. Patients without comorbidities presented similar results to controls, whereas those with comorbidities presented higher neuroticism and lower extraversion scores. PD per se may be unrelated to deviant personality traits, although comorbidities with major depressive disorder and agoraphobia are probably associated with high neuroticism and low extraversion. These traits show a strong correlation with the accumulation and severity of these disorders.

    Full Text Available Background: The aim of this study was determining the relationship between personality traits and happiness in patients with major thalassemia. Materials and Methods: The design of this study was descriptive (correlational study. The target population of this study was all under-treated patients with major thalassemia in Amirkola thalassemia center in 2011. Among these patients, 150 patients were sampled using simple random sampling method and Morgan's table. The data were analyzed by means of calculating Pearson correlation coefficients and multiple linear regression analysis. The patients were asked to complete NEO-five factor Inventory (short form and Oxford happiness inventory. Results: Based on the results, the coefficient of regression analysis of NEO personality factors (big five and happiness was 0.45, which shows a linear relationship between personality factors of NEO and happiness in patients with thalassemia. Thus, there is a statistically significant relationship among personality traits (neuroticism, extroversion, openness, agreeableness, conscientiousness and happiness. Conclusion: Among personality traits, extroversion, flexibility, agreeableness and conscientiousness had positive statistically meaningful relationship with happiness i.e. patients with lower scores in neuroticism, were happier.

    Retrospective clinical cohort study. To compare the clinical and radiographic outcomes of patients who were treated with intrasegmental pars fixation by either laminar compression screw (LS) or a pedicle screw, rod, and laminar hook (PSRH) construct. Spondylolysis is a nonunion defect of the pars interarticularis. In symptomatic spondylolysis, direct repair of the pars interarticularis defect can preserve motion and prevent abnormal stresses at the adjacent levels. Sixteen patients who failed nonoperative treatment and underwent direct pars repair by using LS (n=9) or PSRH (n=7) constructs were included in the study. Clinical outcome was assessed by using the MacNab criteria. Radiologic fusion and complications were evaluated using plain radiographs or computed tomography images and patient charts. The healing rate was 100% after 6 months. The healing time was similar in both the groups: LS, 6.5 months; PSRH, 6.2 months. Patients with PSRH (5.9 mo) were more likely to return to sports earlier relative to patients with LS (7.7 mo). There were no complications in the LS group; in the PSRH group, 1 patient had mild sensory deficit and 2 had superficial wound infections. The MacNab criteria for pain assessment showed an excellent or good outcome in 8 of 9 patients in LS group and 6 of 7 patients in PSRH group. Relative to LS patients, there was a significant increase in surgical time and estimated blood loss among PSRH patients. Either of the mentioned 2 techniques appears to produce acceptable results. Biplanar fluoroscopy and navigation systems could minimize the risk of screw misplacement with LS construct. Familiarity with the various fixation techniques will allow the surgeon to select the most appropriate surgical technique.

Nous avons colligé 278 patientes présentant un cancer du sein dont 14 (5,0%) infectées par le VIH et 264 (95,0%) non infectées par le VIH. Les différences observées entre ces deux groupes de patientes étaient respectivement: âge médian (36,8 vs 49,0 ans), la ménopause (21,4% vs 53,4%), le nombre des patientes traitées (50,0% contre 77,1%) et la survenue de décès (78,6% vs 50,8%). Aucune différence n'a été notée dans la présentation clinique, histologique et le retard de consultation. Dans notre étude, la prévalence de l'infection à VIH chez les patients atteints de cancer du sein est élevée. L’âge jeune des patients, la faible accessibilité au traitement et la mortalité élevée doivent être confirmés par une étude sur un échantillon plus large. PMID:26523196

    Full Text Available Surgical trauma induces activation of the immune system and may cause an increase of inflammatory biomarkers tested postoperatively in septic patients treated for bloodstream infection. The aim of this study was to determine the impact of surgical interventions on the novel sepsis biomarker soluble urokinase plasminogen activator receptor (suPAR and to compare results with those of routine laboratory parameters CRP, PCT, and IL-6 in patients with culture-proven bloodstream infection. Forty-six adult patients with positive blood culture undergoing minor or major surgical intervention were investigated, 12 blood culture positive patients served as control group. Blood was collected 24 hours before and after surgical intervention for determination of the sepsis biomarkers suPAR, CRP, PCT, and IL-6. Within the surgical study cohort, a non-significant increase of suPAR, CRP, and PCT was observed postoperatively ( 0.642; 0.773; 0.087. In contrast, a slight decrease of IL-6 ( 0.599 was observed. A significant correlation was calculated for the pre- and postoperative difference of CRP ( 0.028 and PCT and type of surgical intervention received: after minor surgical intervention only PCT decreased significantly (<0.001, while after major surgical interventions no significant differences were observed for all biomarkers evaluated. In the control group, a significant decrease of CRP ( 0.005 and PCT ( 0.005 was observed. In patients treated adequately for bloodstream infections, postoperative suPAR levels remained uninfluenced of the surgical trauma and might therefore be a reliable parameter for postoperative infectious monitoring. After minor surgical intervention, PCT seems to be the most reliable parameter.

    To establish the relationship between the personality traits of the adolescent and his or her cooperation with the orthodontic treatment. From a sample of 70 adolescent orthodontic patients (46 girls and 24 boys) between 12 and 15 years of age (average age, 13.4 +/- 1.1 years), the patients' personality traits were evaluated by using a personality questionnaire (16 Personality Factors-Adolescent Personal Questionnaire) and the degree of patient cooperation was assessed through the cooperation test (Orthodontic Patient Cooperation Scale [OPCS]). The cutting point for the assessment of cooperation on the OPCS questionnaire (noncooperation vs cooperation) was carried out through the receiver operating characteristic (ROC) analysis of curves. A chi2 test with Yates correction (P < or = .05) was applied to evaluate the associations between the degree of cooperation and the scales of personality, gender, or age. The cutting point for cooperation as assessed by the OPCS by means of ROC analysis was 380. No statistically significant relations were found between the degree of cooperation and the scales of personality, gender, or age. The results of the current study indicate that the personality traits alone of adolescents do not predict cooperation during treatment.

    Cluster headache (CH) has been associated with certain personality traits and lifestyle features, but there are few studies assessing personality profiles in CH. We aimed to analyze personality traits in patients with CH, and to compare them with those found in migraine. We included all consecutive patients with CH attending 5 outpatient offices between January and December 2013. Personality traits were evaluated using the Salamanca screening test, a validated inventory assessing 11 personality traits grouped in 3 clusters. We analyzed the test results in this population, and compared them with those of a migraine population previously assessed with the same test. Eighty patients with CH (75 men, 5 women; mean age, 43.2 ± 9.9 years) were recruited. The reference population consisted of 164 migraine patients (30 men, 134 women; mean age 36.4 ± 12.7 years). In CH patients, the most frequent personality traits were anancastic (52.5 %), anxious (47.5 %), histrionic (45 %), schizoid (42.5 %), impulsive (32.5 %) and paranoid (30 %). When compared to migraine patients, paranoid (p traits (p = 0.007; χ2 test) were significantly more prevalent in CH patients. In logistic regression analysis the paranoid trait was significantly associated with CH (p = 0.001; OR: 3.27, 95 % CI [1.66-6.43]). According to the Salamanca screening test, personality traits included in cluster A (odd or eccentric disorders) are more prevalent in CH patients than in a population of migraineurs. Larger studies are needed to determine whether certain personality traits are related to CH.

    Full Text Available Introduction: Tinnitus is a common complaint in patients referred to otorhinolaryngology clinics and is a condition where one hears a sound without any distinguishable external acoustic source or electrical stimulus. About 3-30% of adults experience different degrees of tinnitus during their life. This study aims to ascertain and compare personality traits between patients with tinnitus and a control group.   Materials and Methods: In a case control study, 66 participants were assessed. The case group consisted of 33 patients who suffered from tinnitus for at least two months, in addition to 33 healthy volunteers who were selected among their family (preferably of the same age and sex. A standard demographic questionnaire and an Eyzenck personality questionnaire were filled for both groups. A tinnitus severity index (TSI questionnaire was only filled for the case group. Data from each group was compared by Mann-Whitney U and Chi-Square tests. SPSS V.18 was the selected software.   Results: Statistical analysis showed a meaningful difference in neuroticism (P=0.001 and extraversion (P=0.001 between the patients and the controls; however, there was no statistical difference between these groups regarding psychotism.   Conclusion:  Tinnitus can be associated with personality characteristics. This study showed that in patients with tinnitus, neuroticism increases and extraversion decreases. Considering the personality and psychotic traits observed in the patients with tinnitus, psychiatric consultation is recommended.

Separate scores were obtained for cancer cells, macrophages and myofibroblasts at the invasive front and in tumour core. We were able to confirm, in an independent patient cohort, the tissue expression and localisation pattern of uPAR as investigated by Immunohistochemistry as well as a significant association between uPAR positivity and increasing tumour stage and tumour grade. This demonstrates the robustness of our previous and current findings. In addition the association between uPAR positive myofibroblasts and poor survival was reproduced. The highest hazard ratios for survival were seen for uPAR positive myofibroblasts both at the invasive front and in tumour core. Evaluating uPAR expression by the actual score showed a significant association between uPAR positive myofibroblasts in tumour core and an increased risk of cancer specific mortality. Our investigations have generated new and valuable biological information about the cell types being involved in tumour invasion and progression through the plasminogen activation system.

    Personality in patients with psychosis, and particularly its relation to psychotic symptoms in recent onset of psychosis (ROP) patients, is understudied. The aims of this research were to study the relation between dimensional and categorical clinical personality traits and symptoms, as well as the effects that symptoms, sex and age have on clinically significant personality traits. Data for these analyses were obtained from 94 ROP patients. The Millon Clinical Multiaxial Inventory and the Positive and Negative Syndrome Scale were used to assess personality and symptoms. Correlational Analysis, Mann-Whitney test, and, finally, logistic regression were carried out. The negative dimension was higher in patients with schizoid traits. The excited dimension was lower for those with avoidant and depressive traits. The anxiety and depression dimension was higher for patients with dependent traits. The positive dimension was lower for patients with histrionic and higher for patients with compulsive traits. Logistic regression demonstrated that gender and the positive and negative dimensions explained 35.9% of the variance of the schizoid trait. The excited dimension explained 9.1% of the variance of avoidant trait. The anxiety and depression dimension and age explained 31.3% of the dependent trait. Gender explained 11.6% of the histrionic trait, 14.5% of the narcissistic trait and 11.6% of the paranoid trait. Finally gender and positive dimension explained 16.1% of the compulsive trait. The study highlights the importance of studying personality in patients with psychosis as it broadens understating of the patients themselves and the symptoms suffered. Copyright © 2017 Elsevier Inc.

    To compare the outcome of pars-plana-modified Ahmed glaucoma valve (AGV) versus limbal-based conventional AGV into the anterior chamber, in patients undergoing penetrating keratoplasty (PK) for glaucoma with coexisting corneal diseases. In this prospective randomized clinical trial, 58 eyes of 58 patients with glaucoma and coexisting corneal disease were divided into two groups. Group 1 (29 eyes of 29 patients) included patients undergoing limbal-based conventional AGV into the anterior chamber (AC) along-with PK and group 2 (29 eyes of 29 patients) included those undergoing pars-plana-modified AGV along-with PK. Outcome measures included corneal graft clarity, intraocular pressure (IOP), number of antiglaucoma medications, and postoperative complications. Patients were followed up for a minimum period of 2 years. Out of 58 eyes (58 patients), 50 eyes (50 patients: 25 eyes of 25 patients each in group 1 and group 2) completed the study and were analyzed. Complete success rate for AGV (group 1: 76%; group 2: 72%; p = 0.842) and corneal graft clarity (group 1: 68%; group 2: 76%; p = 0.081) were comparable between the two groups at 2 years. Graft failure was more in conventional AGV (32%) as compared to pars plana-modified AGV (24%) but not statistically significant (p = 0.078) at 2 years. Though both procedures were comparable in various outcome measures, pars-plana-modified AGV is a viable option for patients undergoing PK, as it provides a relatively better corneal graft survival rate and lesser complications that were associated with conventional AGV.

    To assess the safety and efficacy of a modified technique for pars plana placement of the Ahmed valve in combination with pars plana vitrectomy in the treatment of glaucoma associated with posterior segment disease. Thirty-nine eyes with glaucoma associated with posterior segment disease underwent pars plana vitrectomy combined with Ahmed valve placement. All valves were placed in the pars plana using a modified technique, without the pars plana clip, and using a scleral patch graft. The 24 eyes diagnosed with neovascular glaucoma had an improvement in intraocular pressure from 37.6 mmHg to 13.8 mmHg and best-corrected visual acuity from 2.13 logarithm of minimum angle of resolution to 1.40 logarithm of minimum angle of resolution. Fifteen eyes diagnosed with steroid-induced glaucoma had an improvement in intraocular pressure from 27.9 mmHg to 14.1 mmHg and best-corrected visual acuity from 1.38 logarithm of minimum angle of resolution to 1.13 logarithm of minimum angle of resolution. Complications included four cases of cystic bleb formation and one case of choroidal detachment and explantation for hypotony. Ahmed valve placement through the pars plana during vitrectomy is an effective option for managing complex cases of glaucoma without the use of the pars plana clip.

    Internalized stigma of mental disorders has significant negative outcomes for patients with bipolar disorder and their families. The aim of this study is to evaluate the association between personality traits and internalized stigma of mental disorders in bipolar patients and their treatment partners. Five different questionnaires were utilized in this study: (1) Demographic data questionnaire, (2) Millon Clinical Multiaxial Inventory-III (MCMI-III) for personality traits, (3) Internalized Stigma of Mental Illness (ISMI) for stigma, (4) Self Report Manic Inventory (SRMI) for mania and (5) Center for Epidemiological Studies-Depression Scale (CES-D) for depression. The scores of personality traits were combined to create externalizing and internalizing personality trait scores. Results showed that patients with bipolar disorder and their treatment partners both experienced internalized stigma of mental health disorders. There was a significant positive correlation between internalized stigma and internalizing personality traits, but not externalizing traits. In a multi-variate regression analysis, internalizing personality trait score was found to be a significant predictor of internalized stigma. In conclusion, patients with bipolar disorder and their treatment partners perceive higher level of internalized stigma of mental disorders if they have internalizing personality traits.

    2010-03-01

    Full Text Available Abstract The medical cost associated with back pain in the United States is considerable and growing. Although the differential diagnosis of back pain is broad, epidemiological studies suggest a correlation between adult and adolescent complaints. Injury of the pars interarticularis is one of the most common identifiable causes of ongoing low back pain in adolescent athletes. It constitutes a spectrum of disease ranging from bone stress to spondylolysis and spondylolisthesis. Bone stress may be the earliest sign of disease. Repetitive bone stress causes bone remodeling and may result in spondylolysis, a non-displaced fracture of the pars interarticularis. A fracture of the pars interarticularis may ultimately become unstable leading to spondylolisthesis. Results in the literature support the use of bone scintigraphy to diagnose bone stress in patients with suspected spondylolysis. Single photon emission computed tomography (SPECT provides more contrast than planar bone scintigraphy, increases the sensitivity and improves anatomic localization of skeletal lesions without exposing the patient to additional radiation. It also provides an opportunity for better correlation with other imaging modalities, when necessary. As such, the addition of SPECT to standard planar bone scintigraphy can result in a more accurate diagnosis and a better chance for efficient patient care. It is our expectation that by improving our ability to correctly diagnose bone stress in patients with suspected injury of the posterior elements, the long-term cost of managing this condition will be lowered.

    To describe the relationship between personal values and personality traits in cocaine-using patients and analyze their specificity in the explanation of different types of constructs. A study was carried out to explore the association between these variables in a group of 230 patients receiving treatment for cocaine dependence. The Portrait Values Questionnaire was used for measuring personal values, while the Big-Five Factors Questionnaire was used to measure personality traits. In addition, we explored the relationship of values and traits with the variables "degree of satisfaction with life" (life satisfaction) and "belonging to a religious association" (religiosity). A significant association was found between personal values and personality traits. At the same time, their conceptual and empirical differences were revealed, as it was demonstrated that personal values better explain "belonging to a religious association", whilst personality traits better explain "degree of satisfaction with life". Thus, it was found that personal values better explain behaviours that depend on greater cognitive control, while personality traits would have more influence on tendencies and behaviours that are subject to lower cognitive control levels. Considering the relationship between the two constructs, and given that cocaine use is associated with both high and low cognitive control, in explanations of cocaine use it would be appropriate to take into account the explanatory contribution of personal values and personality traits in a complementary way.

    Full Text Available Introduction: During the last few years, physical activity has become a therapeutic tool and a protective mechanism for the elderly; it reduces cardiovascular risk in patients undergoing different types of dialysis and receiving palliative care. Objective: The aim of this study was to establish the inclusion criteria for a therapeutic physical activity program through the use of the PAR-Q & YOU Questionnaire with elderly patients treated with different types of hemodialysis, and to relate it with cardiovascular risk factors. Methods: Pearson's chi-squared test was used to determine the possible association among variables, considering the medical history and discomfort caused by physical activity against the results of PAR-Q & YOU. Binary logistic regression was used with the variables in the chi-squared test. Conclusions: Through logistic regression, we found that cardiovascular history was 10.44 times more significant to establish the relevance of the PAR-Q & YOU as a basic assessment instrument for the inclusion in a physical activity program which is part of a physiotherapy-led renal rehabilitation.

    Full Text Available Abstract Background Serum concentrations of soluble urokinase-type plasminogen activator receptor (suPAR have a strong independent association with HIV-1-related mortality. The practical utility of plasma suPAR in assessing short-term all-cause mortality risk was evaluated in patients with advanced immunodeficiency enrolling in an antiretroviral treatment (ART programme in South Africa. Methods An enzyme-linked immunosorbent assay (ELISA was used to measure plasma concentrations of suPAR in patients at the time of enrolment to the ART programme. The association between plasma suPAR concentrations, baseline patient characteristics and cohort outcomes after 4 months of ART were determined. Results Patients (n = 293, 70% female had a median age of 33 years and were followed up for a median of 5 months from enrolment. The median CD4 cell count was 47 cells/μl (IQR = 22–72 and 38% of patients had WHO stage 4 disease. 218 (74% patients remained alive after 4 months of ART; 39 (13% died and 36 (12% were lost to the programme for other reasons. Patients who died had significantly higher plasma suPAR concentrations compared to those who either survived (P 10 suPAR concentrations were significantly associated with lower CD4 cell counts, WHO clinical stage 4 disease and male sex. In multivariate analysis to identify factors associated with death, log10 suPAR concentration was the most strongly associated variable (P Conclusion Plasma suPAR concentration was the strongest independent predictor of short-term mortality risk among patients with advanced immunodeficiency enrolling in this ART programme. However, lack of a discriminatory threshold did not permit this marker to be used to triage patients according to short-term mortality risk.

    Individuals with body dysmorphic disorder (BDD) have been postulated to have schizoid, narcissistic, and obsessional personality traits and to be sensitive, introverted, perfectionistic, and insecure. However, data on personality traits and disorders in BDD are limited. This study assessed 148 subjects with BDD, 26 of whom participated in a fluvoxamine treatment study; 74 subjects were assessed for personality disorders with the Structured Clinical Interview for DSMIII-R Personality Disorders (SCID-II), 100 subjects completed the NEO-Five Factor Inventory (NEO-FFI), and 51 subjects completed the Rathus Assertiveness Scale. Forty-two subjects (57%) had one or more personality disorders, with avoidant personality disorder (43%) being most common, followed by dependent (15%), obsessive-compulsive (14%), and paranoid (14%) personality disorders. On the NEO-FFI, the mean scores were in the very high range for neuroticism, the low range for extraversion and conscientiousness, the low-average range for agreeableness, and the average range for openness to experience. On the Rathus Assertiveness Scale, the mean score was -17.1 +/- 32.0 for women and -17.0 +/- 32.3 for men. Among fluvoxamine responders, the number of personality disorders significantly decreased between the study baseline and endpoint. These findings suggest that the rate of personality disorders in BDD is relatively high, with avoidant personality disorder being most common. The high neuroticism scores and low extraversion scores are consistent with this finding.

    Soluble urokinase plasminogen activator receptor (suPAR) serum concentrations have recently been described to reflect the severity status of systemic inflammation. In this study, the diagnostic accuracy of suPAR, C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6) to predict bacteremia in patients with systemic inflammatory response syndrome (SIRS) was compared. A total of 132 patients with SIRS were included. In 55 patients blood cultures had resulted positive (study group 1, Gram positive bacteria: Staphylococcus aureus and Streptococcus spp., n=15; study group 2, Gram-negative bacteria, n=40) and 77 patients had negative blood culture results (control group, n=77). Simultaneously with blood cultures suPAR, CRP, PCT, IL-6 and white blood count (WBC) were determined. SuPAR values were significantly higher in study group 1 (median 8.11; IQR 5.78-15.53; p=0.006) and study group 2 (median 9.62; IQR 6.52-11.74; p<0.001) when compared with the control group (median 5.65; IQR 4.30-7.83). ROC curve analysis revealed an AUC of 0.726 for suPAR in differentiating SIRS patients with bacteremia from those without. The biomarkers PCT and IL-6 showed comparable results. Regarding combinations of biomarkers multiplying suPAR, PCT and IL-6 was most promising and resulted in an AUC value of 0.804. Initial suPAR serum concentrations were significantly higher (p=0.028) in patients who died within 28 days than in those who survived. No significant difference was seen for PCT, IL-6 and CRP. In conclusion, suPAR, IL-6 and PCT may contribute to predicting bacteremia in SIRS patients. Copyright © 2012 The Canadian Society of Clinical Chemists. Published by Elsevier Inc.

    Suicide is a major social and clinical problem in Asia. Although studies have suggested that personality traits are possible risk factors for suicide, no study has been conducted among Chinese to compare the temperament traits of suicidal and non-suicidal mood disorder patients with those of healthy controls. This study compared temperament traits of two patient groups, those with a mood disorder who have attempted suicide (n=204), and those with a mood disorder who have not attempted suicide (n=160), and compared the traits of these patients to those of healthy controls (n=178), assessed by Cloninger's Tridimensional Personality Questionnaire and the Brown-Goodwin Aggression Inventory. Patients with suicidal attempts had significantly higher novelty seeking and aggression scores than healthy controls and patients without suicidal attempts. Two groups of patients with mood disorder had significantly higher harm avoidance scores than the healthy controls. However, patients with suicidal attempts did not have higher harm avoidance scores than patients without suicidal attempts. This study confirms findings that harm avoidance and mood disorder are related, and extends them by suggesting that those with a mood disorder and suicide attempts have higher novelty seeking and lifetime aggression scores than those without suicidal attempt, either patients or healthy controls.

    Full Text Available Objective: The objective was to evaluate the relationship between personality traits, pain perception, and person′s attitude toward orthodontic treatment. Materials and Methods: The sample comprised of two groups: Group 1 consisted of 100 treated subjects (50 males, 50 females; average age, 16.07 ± 1.36 years, and Group 2 consisted of 100 untreated subjects (50 males, 50 females; average age, 16.07 ± 1.41 years. The instrument for data collection was a questionnaire that included an assessment of patients′ personality profiles, pain expectation for untreated subjects, pain experience for treated subjects, and attitude toward orthodontic treatment. Results: Gender and treatment status did not affect pain perception and attitude of a person toward orthodontic treatment. There was a strong relationship between pain perception and attitude with Pearson′s correlation of 0.367 and P ≤ 0.0001. With one unit increase in attitude there was 0.43 units increase in pain. Patients with high levels of trait neuroticism (P = 0.01 and low levels of trait conscientiousness (P = 0.02 experienced more pain. Patients with high levels of trait conscientiousness showed better attitude (P = 0.01. Conclusion: Personality traits, neuroticism, and conscientiousness have effect on pain perception and attitude of patients toward orthodontic treatment. Patients with better attitude experienced less pain and patients with less pain exhibited better attitude.

    We developed this study to investigate the association of fibromyalgia with personality traits, controlling for depression and other potential confounders. We assessed personality traits using the Cloninger's Temperament and Character Inventory (TCI) in 78 female patients with fibromyalgia and in a control group of 78 subjects without fibromyalgia. The Mini-International Neuropsychiatric Interview was used to assess depression and anxiety diagnoses. To investigate the association between fibromyalgia and the Cloninger's Temperament and Character Inventory we performed unadjusted and adjusted analyses of covariance, using the TCI score as dependent variable and adjusting the model for depression, anxiety and for clinical and socio-demographic variables. We used a backward selection method to choose the final model. In the unadjusted analysis, fibromyalgia was associated with all personality traits, except persistency. After adjusting for depression and anxiety, patients with fibromyalgia presented decreased novelty seeking compared to controls; the differences in other personality traits were no longer significant. Novelty seeking was also correlated with the length of history of fibromyalgia and pain intensity. Decreased novelty seeking may be a personality trait associated with fibromyalgia. Depression and anxiety should be considered potential confounders in the evaluation of personality traits in this population.

    The purpose of this study was to investigate temperament and character traits in patients with conversion disorder and the relation of these traits with dissociative symptoms. Sixty patients (60) diagnosed with conversion disorder according to DSM-IV-TR and 60 healthy volunteers were included in the study. All participants' temperament and character traits were determined using Cloninger's Temperament and Character Inventory (TCI). Patients with conversion disorder were divided into two subgroups using the Dissociative Experiences Scale (DES), dissociative (n=30, 50%) and non-dissociative (n=30, 50%). The two conversion disorder subgroups were compared with the control group in terms of temperament and character traits. Correlation analysis was also performed between TCI and DES scores in the entire conversion group. Novelty seeking (NS) scores were lower in both the dissociative and non-dissociative groups compared to the control group. Harm avoidance (HA) scores were higher in the dissociative group than in the control group. Reward dependence (RD) scores were lower in the dissociative group than in the non-dissociative and control group. Self-directedness (SD) scores were lower in the dissociative group than in the control group. Self-transcendence (ST) scores were higher in the dissociative group than in the non-dissociative group. DES scores were negatively correlated with RD and SD scores in the entire conversion group and positively correlated with ST scores. Low NS temperament traits may be associated with conversion disorder. High HA and low RD temperament traits and low SD and high ST character traits may be associated with pathological dissociation in patients with conversion disorder.

    To examine the associations between personality traits and suicidal ideation (SI) and attempt (SA) in mood disorder patients and community controls. We recruited 365 bipolar, 296 major depressive disorder patients, and 315 community controls to assess their lifetime suicidality. Participants filled out self-reported personality questionnaires to collect data of personality traits, including novelty seeking (NS), harm avoidance (HA), extraversion (E), and neuroticism (N). We used logistic regression models adjusted for diagnoses to analyze combinational effects of personality traits on the risk of suicide. Additionally, radar charts display personality profiles for suicidal behaviours by groups. All personality traits were associated with the risk of suicidality with various effect size, except for E that showed protective effect. High N or HA had prominent and independent risk effects on SI and SA. Combinations of high N and low E, or high HA and NS were the risk personality profiles for suicidality. Higher N scores further distinguished SA from SI in mood disorder patients. Introvert personality traits showed independent risk effects on suicidality regardless of diagnosis status. Among high-risk individuals with suicidal thoughts, higher neuroticism tendency is further associated with increased risk of suicide attempt. © 2017 John Wiley & Sons A/S.

    Aim of this research was to establish effects and influence of personality traits on sexual functioning of schizophrenic and depressive patients, compared to healthy individuals. 300 participants were included in this research. For patients suffering from schizophrenia it was established that the more they are open to experience and the less they are neurotic their sexual drive is stronger. For patients suffering from depression it was established that the more they are open to experience and conscientious and the less they are agreeable their sexual drive is stronger. Furthermore, higher openness is a significant predictor for easier sexual arousal and the more those patients are conscientious and the less they are agreeable easier is for them to achieve orgasms. Personality traits proved to be significant predictors of sexual functioning in schizophrenic and depressive patients, but not in healthy individuals.

    Full Text Available Background: Cardiac dysfunctions have been recognized as a common complication of sickle cell anaemia (SCA, and together with pulmonary disorder accounts for many deaths in these patients. However, sickle cell traits appear clinically normal, although they have genetic abnormality. The aim of this study was to assess the effect of sickle cell trait on cardiac prognostic markers by measuring high density lipoprotein (HDL-C, low density lipoprotein (LDL-C, cardiac creatine kinase (CK-MB, ultra-sensitive C reactive protein (us-CRP, total homocysteine (Hyc, and N-terminal pro-brain natriuretic peptide (NT-pro BNP tests in adult Sudanese patients with sickle cell trait.Methods: A cross-sectional study was performed in 200 healthy volunteers as a control group and 200 diagnosed patients with sickle cell trait. It was carried out in Khartoum Specialized Hospital, Al-Bayan Hospital, Obayed Clinical Center and Dr. Nadir Specialized Hospital, Sudan between January 2015 and January 2016. All participants were between 20-32 years old. LDL-C, HDL-C, CK-MB, NT-proBNP and hs-CRP concentrations were measured by Hitachi 912 full-automated Chemistry Analyzer (Roche Diagnostics, Germany as manufacturer procedure, while homocysteine level was measured by ELISA technique using special kit.Results: When compared to control group, the levels of LDL-C, hs-CRP and NT-proBNP revealed significant increase in patients’ sera (p<0.001, while Hyc and CK-MB levels were increased insignificantly in patients with SCT (p=0.069, p=0.054 respectively. On the other hand, comparison to control group, HDL-C showed insignificant reduction in patients (p=0.099.Conclusion: The results suggest that sickle cell trait increased the risk of patient-related complication secondary to cardiac dysfunction.

    Full Text Available Abstract Background: Diabetes is a serious problem and self- management is effective factor for diabetes control. Personality trait is one of the important factors in diabetes self- management. In this study, purpose was determination of effective personality traits in self- management. Material and Methods: In this cross sectional study, data were collected from a convenience sample of 396 diabetic patients, using self- management and Big five personality Scales. For data analysis, multiple linear regression models were used. Results: Among five personality traits, the most effective traits in self- management were conscientiousness, openness, and extraversion (R2= 32%. Conscientiousness and openness were significant predictors for all of self- management aspects. Extraversion was effective factors in self- regulation, self- integration, and following treatment. Conclusion: The education for diabetic patients with neuroticism and agreeableness traits is necessary and Patients with conscientiousness, openness, and extraversion traits can be used as model in educational process.

    Autism spectrum disorder often co-occurs with other psychiatric disorders. Although a high prevalence of autistic-like traits/symptoms has been identified in the pediatric psychiatric population of normal intelligence, there are no reports from adult psychiatric population. This study examined whether there is a greater prevalence of autistic-like traits/symptoms in patients with adult-onset psychiatric disorders such as major depressive disorder (MDD), bipolar disorder, or schizophrenia, and whether such an association is independent of symptom severity. The subjects were 290 adults of normal intelligence between 25 and 59 years of age (MDD, n=125; bipolar disorder, n=56; schizophrenia, n=44; healthy controls, n=65). Autistic-like traits/symptoms were measured using the Social Responsiveness Scale for Adults. Symptom severity was measured using the Positive and Negative Symptoms Scale, the Hamilton Depression Rating Scale, and/or the Young Mania Rating Scale. Almost half of the clinical subjects, except those with remitted MDD, exhibited autistic-like traits/symptoms at levels typical for sub-threshold or threshold autism spectrum disorder. Furthermore, the proportion of psychiatric patients that demonstrated high autistic-like traits/symptoms was significantly greater than that of healthy controls, and not different between that of remitted or unremitted subjects with bipolar disorder or schizophrenia. On the other hand, remitted subjects with MDD did not differ from healthy controls with regard to the prevalence or degree of high autistic-like traits/symptoms. A substantial proportion of adults with bipolar disorder and schizophrenia showed high autistic-like traits/symptoms independent of symptom severity, suggesting a shared pathophysiology among autism spectrum disorder and these psychiatric disorders. Conversely, autistic-like traits among subjects with MDD were associated with the depressive symptom severity. These findings suggest the importance of

    The aim of this study was to document and compare adverse childhood experiences, and personality profiles in women with borderline personality disorder (BPD) and their sisters, and to determine how these factors impact current psychopathology. Fifty-six patients with BPD and their sisters were compared on measures assessing psychopathology, personality traits, and childhood adversities. Most sisters showed little evidence of psychopathology. Both groups reported dysfunctional parent-child relationships and a high prevalence of childhood trauma. Subjects with BPD reported experiencing more emotional abuse and intrafamilial sexual abuse, but more similarities than differences between probands and sisters were found. In multilevel analyses, personality traits of affective instability and impulsivity predicted DIB-R scores and SCL-90-R scores, above and beyond trauma. There were few relationships between childhood adversities and other measures of psychopathology. Sensitivity to adverse experiences, as reflected in the development of psychopathology, appears to be influenced by personality trait profiles.

    There is a longstanding tradition that connects temperament pathology and personality disorders. Emotions are the major constituents of temperament. In mammals, seven primary emotions have been identified: SEEKING, FEAR, CARE, RAGE, SADNESS/PANIC, LUST and PLAY. The study aimed at exploring the relationship between primary emotions and personality disorders (PDs). Five hundred forty-six patients with different degrees and qualities of personality pathology, admitted to treatment in specialized PD services, were diagnosed according to Structured Clinical Interview for DSM-IV Axis II Personality Disorders, and their primary emotional profiles were assessed by the Affective Neuroscience Personality Scales. The Affective Neuroscience Personality Scales explained 19% of the variance in borderline and avoidant criteria. The DSM-IV PD categories displayed different patterns of association to the primary emotions, e.g. the borderline PD profile suggested low thresholds for RAGE and SADNESS, but on the positive side a propensity for SEEKING. In contrast, the dependent PD profile suggested a low threshold for SADNESS but a high threshold for RAGE and SEEKING. The results are promising for a more coherent and evolution-based overall theory of PDs, and the correlations found in this study indicate testable causal pathways to PDs.

  1. Non-suicidal Self-Injury in Eating Disordered Patients: Associations with Heart Rate Variability and State-Trait Anxiety

    Directory of Open Access Journals (Sweden)

    Cristina Giner-Bartolome

    2017-07-01

    Full Text Available Background: Non-suicidal self-injury (NSSI is commonly present in individuals with eating disorders (EDs and is often employed as a maladaptive emotion regulation strategy to avoid or abate negative emotions. One of the most prevalent negative emotions experienced by self-injurers is anxiety; however, this emotion has not been extensively studied in this population. Thus, the aim of our study was to investigate the influence of anxiety on NSSI in patients with ED from two different dimensions: state anxiety and trait anxiety.Methods: The study comprised a total of 66 females: 12 ED patients with NSSI, 32 ED patients without a history of NSSI, and 22 healthy controls. State and trait anxiety were assessed by means of State-Trait Anxiety Inventory (STAI-S-T and physiological data [i.e., heart rate variability (HRV] were collected.Results: STAI-trait scores were significantly higher in ED patients with NSSI than ED patients without NSSI. Furthermore, when conducting logistic regression analyses higher STAI-trait scores were associated with NSSI in ED patients. However, no differences in STAI-state scores and HRV were found between ED patients with and without NSSI.Discussion: The present findings suggest that anxiety as a trait is associated with the use of maladaptive strategies (i.e., NSSI in ED patients. These results uphold the need to target trait anxiety in ED treatment in order to prevent possible NSSI behaviors.

    Although there is evidence that childhood perfectionistic traits predate the onset of eating disorders, few studies to date have examined the prevalence and clinical correlates of these traits in patients with anorexia nervosa (AN) and their unaffected sisters. The aim of this work was to study the prevalence of childhood obsessive-compulsive traits in patients with lifetime AN, their unaffected sisters and healthy women. A total of 116 AN patients, 32 healthy sisters and 119 controls were assessed by the EATATE Interview to assess traits such as perfectionism, inflexibility, rule-bound traits, drive for order and symmetry, and excessive doubt and cautiousness. Both self-report and maternal reports were collected. AN patients reported more childhood obsessive-compulsive traits than their healthy sisters and controls. In contrast, no differences between healthy controls and unaffected sisters emerged. In patients with AN, a dose-response relationship was found between the number of childhood obsessive-compulsive traits and psychopathology, including body image distortion, thus indicating that these traits are an important feature to be considered in assessing and treating eating disorders.

    Full Text Available Pegfilgrastim (Neulasta is a recombinant filgrastim (human granulocyte colony-stimulating factor (G-CSF attached to a polyethylene glycol (PEG molecule and is given as part of chemotherapy regimens that are associated with significant myelosuppression and risk for febrile neutropenia. Prescribing information available on manufacturer’s website for the drug warns us about possible severe sickle cell crises related to the medication but does not report the actual incidence or the use in patients with sickle cell trait. Caution is advised when using it in patients with sickle cell disease. Here we present a case of a Caucasian female with known sickle cell trait (SCT with no prior complications who developed a presumed sickle cell crisis after getting Neulasta, as a part of the chemotherapy regimen used to treat her breast cancer. Based on our literature review, this appears to be the first case report of a patient with SCT developing a sickle cell crisis with the pegylated form of recombinant filgrastim. Given the dearth of literature regarding the use of G-CSF and its related pegylated forms in patients with sickle cell anemia and sickle cell trait, a discussion of potential mechanisms and review of current literature and guidelines is also presented.

    2012-06-01

    This study reviews empirical evidence on the association between personality traits and Parkinson's disease (PD), with a twofold aim. First, to better identify non-motor symptoms, such as affective symptoms and personality changes, that could help to define the pre-motor phase of PD; second, to better understand the neurobiological bases of personality traits, a goal that is not fully accomplished by a purely anatomical approach. A literature review was performed on studies of personality traits in PD patients, in electronic databases ISI Web of Knowledge, Medline and PsychInfo, conducted in July 2011. We found evidence that the existence of a characteristic premorbid personality profile of PD patients is not actually sustained by robust empirical evidence, mainly due to the methodological bias of the retrospective assessment of personality; PD patients present a personality profile of low novelty seeking and high harm avoidance. We concluded that the definition of a pre-motor phase of PD, based on non-motor symptoms, should search for the presence of concomitant affective disorders and for a positive psychiatric history for affective disorders rather than for a typical personality profile or personality changes. The low novelty seeking profile is probably related to the dopaminergic deficit, while the high harm avoidance profile is probably associated with the presence of affective disorders. Clinical implications of these findings, in regard to personality assessment and pharmacological treatments in PD, are also discussed.

    We investigated the relationship between personality traits and response to treatment with the tetracyclic antidepressant mianserin or placebo in patients with functional gastrointestinal disorder (FGD) without psychopathology. Forty-eight patients completed the Buss-Durkee Hostility Inventory, Neuroticism Extroversion Openness -Personality Inventory (NEO-PI), and Eysenck Personality Questionnaire (EPQ), neuroticism + lie subscales, before they were consecutively allocated to a 7-week double-blind treatment study with mianserin or placebo. Treatment response to pain and target symptoms were recorded daily with the Visual Analogue Scale and Clinical Global Improvement Scale at every visit. A low level of neuroticism and little concealed aggressiveness predicted treatment outcome with the antidepressant drug mianserin in non-psychiatric patients with FGD. Inversely, moderate to high neuroticism and marked concealed aggressiveness predicted poor response to treatment. These findings were most prominent in women. Personality traits were better predictors of treatment outcome than serotonergic sensitivity assessed with the fenfluramine test. Assessment of the personality traits negativism, irritability, aggression, and neuroticism may predict response to drug treatment of FGD even when serotonergic sensitivity is controlled for. If confirmed in future studies, the findings point towards a more differential psychopharmacologic treatment of FGD.

    Autism spectrum disorder (ASD) is a highly heritable neurodevelopmental disorder with a complex genetic architecture. To identify genetic variants underlying ASD, we performed single-variant and gene-based genome-wide association studies using a dense genotyping array containing over 2.3 million single-nucleotide variants in a discovery sample of 160 families with at least one child affected with non-syndromic ASD using a binary (ASD yes/no) phenotype and a quantitative autistic trait. Replication of the top findings was performed in Psychiatric Genomics Consortium and Erasmus Rucphen Family (ERF) cohort study. Significant association of quantitative autistic trait was observed with the TTC25 gene at 17q21.2 (effect size=10.2, P-value=3.4 × 10 -7 ) in the gene-based analysis. The gene also showed nominally significant association in the cohort-based ERF study (effect=1.75, P-value=0.05). Meta-analysis of discovery and replication improved the association signal (P-value meta =1.5 × 10 -8 ). No genome-wide significant signal was observed in the single-variant analysis of either the binary ASD phenotype or the quantitative autistic trait. Our study has identified a novel gene TTC25 to be associated with quantitative autistic trait in patients with ASD. The replication of association in a cohort-based study and the effect estimate suggest that variants in TTC25 may also be relevant for broader ASD phenotype in the general population. TTC25 is overexpressed in frontal cortex and testis and is known to be involved in cilium movement and thus an interesting candidate gene for autistic trait.

  8. Molecular characterization of hemoglobin D Punjab traits and clinical-hematological profile of the patients

    Directory of Open Access Journals (Sweden)

    Sanjay Pandey

    Full Text Available CONTEXT AND OBJECTIVE: Hemoglobin (Hb D hemoglobinopathies are widespread diseases in northwestern India and usually present with mild hemolytic anemia and mild to moderate splenomegaly. The heterozygous form of Hb D is clinically silent, but coinheritance of Hb D with Hb S or beta-thalassemia produces clinically significant conditions like thalassemia intermedia of moderate severity. Under heterozygous conditions with coinheritance of alpha and beta-thalassemia, patients show a degree of clinical variability. Thus, our aim was to molecularly characterize the Hb D trait among individuals who were clinically symptomatic because of co-inheritance of alpha deletions or any beta-globin gene mutations. DESIGN AND SETTING: This was a cross-sectional study conducted in an autonomous tertiary-care hospital. METHODS: Complete blood count and red cell indices were measured using an automated cell analyzer. Quantitative assessment of hemoglobin Hb F, Hb A, Hb A2 and Hb D was performed by means of high performance liquid chromatography (HPLC. DNA extraction was done using the phenol-chloroform method. Molecular analyses on common alpha deletions and common beta mutations were done using the Gap polymerase chain reaction and Amplification Refractory Mutation System, respectively. RESULTS: We evaluated 30 patients and found clinical variation in the behavior of Hb D traits. In six patients, the Hb D traits were clinically symptomatic and behaved like those of thalassemia intermedia. Molecular characterization showed that three out of these six were IVS-1-5 positive. CONCLUSIONS: HPLC may not be the gold standard for diagnosing symptomatic Hb D Punjab traits. Hence, standard confirmation should include molecular studies.

    In this naturalistic study of 55 outpatients selected for long-term psychodynamic psychotherapy, two Swedish assessment instruments are presented (the Karolinska Psychodynamic Profile and the Karolinska Scales of Personality), and the significance of psychodynamic criteria for the selection of patients is discussed. Thirty patients (55%) fulfilled criteria for a DSM-III-R diagnosis. The most prominent psychodynamically defined character pathology was found in the areas of coping with aggressive affects; dependency and separation; frustration tolerance; and impulse control. Some psychodynamically defined character traits, particularly poor frustration tolerance, were related to symptomatic suffering. PMID:9407473

    2018-05-01

    The main aim of this study was to examine the relationship between therapists' emotional responses and patients' personality evaluated by 3 dimensional diagnostic approaches empirically derived from the Shedler-Westen Assessment Procedure-200 (SWAP-200; Westen & Shedler, 1999a, 1999b): Two of these rely on the 5-factor model (FFM) domains, that were assessed with different SWAP-200 FFM versions developed by Shedler and Westen (SW-FFM scales; 2004) and McCrae, Löckenhoff, and Costa (MLC-FFM scales; 2005); the third approach is based on a multifaceted model of personality syndromes (SWAP personality dimension scales; see Shedler & Westen, 2004). A national sample of psychiatrists and psychologists (N = 166) of various theoretical orientations completed the Therapist Response Questionnaire (TRQ; Zittel Conklin & Westen, 2003) to identify patterns of therapist response, and the SWAP-200 to assess personality regarding a patient currently in their care. The findings showed good levels of construct validity between the SW-FFM and MLC-FFM scales, with the exception of the Openness trait. Moreover, specific SW-FFM and MLC-FFM scales were significantly associated with distinct SWAP personality dimension scales according in a conceptually meaningful nomological network. Although there were significant, theoretically coherent, and systematic relationships between therapists' responses and patients' personality features, overall the contribution of the SW-FFM and MLC-FFM traits in predicting therapists' responses was less sizable than the SWAP personality dimensions. These results seem to confirm the diagnostic and therapeutic value of countertransference as an essential tool in understanding psychological traits/dimensions that underlie the patients' psychopathology, both from within and outside of the FFM.

    Full Text Available INTRODUCTION: Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia. OBJECTIVE: The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance. METHOD: A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale. RESULTS: A current major depressive episode was diagnosed in 28 (40.5% of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found. CONCLUSIONS: The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.

    The hemodynamic performance of prosthetic tissue valves is influenced by valve design and valve-specific sizing strategies. Design determines the actual geometric opening area (GOA) of the prosthetic valve and sizing strategy its actual chosen size. Currently, hemodynamic performance is assessed by determining the effective orifice area (EOA; derived from the continuity equation by relating flow velocities with the area of the left ventricular outflow tract [LVOTA]). The question whether a valve is too small (patient-prosthesis mismatch [PPM]) is currently addressed by relating EOA to body surface area (EOA index [EOAi]). However, this relation may not be appropriate because the EOAi relates flow velocity to patient-specific anatomic parameters twice (i.e., LVOTA and body surface area). This potential confounder may explain the controversies regarding PPM. However, intuitively, leaving a gradient behind after aortic valve replacement cannot be irrelevant. PPM becomes even more relevant with transcatheter valve-in-valve implantation, where a second prosthesis is taking up inner space of a valve that may have already been too small initially. Thus, a reliable method to determine the presence of PPM is needed. The Prosthesis-to-Annulus Relation I (PAR I) trial is a German multicenter study assessing the relation between the prosthetic GOA and the LVOTA as a potentially new parameter for the prediction of hemodynamic outcome. The results may possibly guide future valve size selection and may allow prediction of functionally relevant PPM. Here, we will demonstrate the shortcomings of the currently applied EOAi for the assessment of hemodynamic relevance and present the rationale for the PARI trial, which recently started recruiting patients.

    Full Text Available Objective: This study is carried on to compare personality traits, coping strategies, and attributional styles of opiate-dependent patients and healthy people. Materials & Methods: In this cross-sctional and comparative research, three scales Eysenk Personality Questionaire RS (EPQ-RS, Coping Response Inventory (CRI, and Attributional Style Questionnaire (ASQ are used to measure the mentioned variables on 158 people (78 opiate-dependent patient and 80 healthy people selected by accessible sampling method. Research data were examined on the basis of T-test for independent groups and logistic regression. Results: Results of T-test showed that there were significant differences between healthy and patient group in Coping Response Inventory and Personality Traits Subscale(except Lying subscale and attribution styles for negative events (P<0.001. Logistic regression results showed that all of these variables which entered in model, are able to predict distinction one group from other patient group and healthy one in a meaningful way(P<0.001. Conclusion: opiate-dependent patients when they face problems significantly use problem-solving strategies, social support seeking, and cognitive evaluation significantly less than healthy group and use physical inhibition and emotional inhibition significantly more than the healthy group. Also, drug-dependent patients in terms of tendency to Neuroticism, psychoticism and introversion were significantly higher than the healthy group, and they had more pessimistic attributional style towards negative events. On the other hand it became apparent that some aspects of personality characteristics, coping strategies, and attributional style considerably were able to distinguish healthy people from opiate-dependent patients.

    Résumé Objectif Présenter aux médecins de famille des renseignements de base pour faire comprendre l’épidémiologie, la pathogenèse, l’histologie et l’approche clinique au diagnostic de la pelade par plaques. Sources des données Une recension a été effectuée dans PubMed pour trouver des articles pertinents concernant la pathogenèse, le diagnostic et le pronostic de la pelade par plaques. Message principal La pelade par plaques est une forme de perte pileuse auto-immune dont la prévalence durant une vie est d’environ 2 %. Des antécédents personnels ou familiaux de troubles auto-immuns concomitants, comme le vitiligo ou une maladie de la thyroïde, peuvent être observés dans un petit sous-groupe de patients. Le diagnostic peut souvent être posé de manière clinique en se fondant sur la perte de cheveux non cicatricielle et circulaire caractéristique, accompagnée de cheveux en « point d’exclamation » en périphérie chez ceux dont le problème en est aux premiers stades. Le diagnostic des cas plus complexes ou des présentations inhabituelles peut être facilité par une biopsie et un examen histologique. Le pronostic varie largement et de mauvais résultats sont associés à une apparition à un âge précoce, une perte importante, la variante ophiasis, des changements aux ongles, des antécédents familiaux ou des troubles auto-immuns concomitants. Conclusion La pelade par plaques est une forme auto-immune de perte de cheveux périodiquement observée en soins primaires. Les médecins de famille sont bien placés pour identifier la pelade par plaques, déterminer la gravité de la maladie et poser le diagnostic différentiel approprié. De plus, ils sont en mesure de renseigner leurs patients à propos de l’évolution clinique de la maladie ainsi que du pronostic général selon le sous-type de patients.

    Temperament and personality traits have been suggested as endophenotypes for bipolar disorder based on several lines of evidence, including heritability. Previous work suggested an anxious-reactive factor identified across temperament and personality inventories that produced significant group discrimination and could potentially be useful in genetic analyses. We have attempted to further characterize this factor structure in a sample of bipolar patients. A sample of 1195 subjects with bipolar I disorder was evaluated, all with complete data available. Dimension reduction across two inventories identified 18 factors explaining 39% of the variance. The two largest factors reflected affective instability and general anxiety/worry, respectively. Subsequent analyses of the clinical features associated with bipolar disorder revealed specificity for the factors in a predictable pattern. Cluster analysis of the factors identified a subgroup defined by a strong lack of general anxiety and low affective instability represented by the first two factors. The remaining subjects could be distinguished into two clusters by the presence of either more positive characteristics, including persistence/drive, spirituality, expressivity, and humor, or more negative characteristics of depression and anxiety. These analyses involved bipolar I subjects only and must be extended to other bipolar spectrum diagnoses, unaffected relatives, and individuals at risk. These results suggest that temperament and personality measures access latent traits associated with important clinical features of bipolar disorder. By translating clinical variables into quantitative traits, we may identify subgroups of bipolar patients with distinct clinical profiles, thereby facilitating both individual treatment strategies and genetic analyses.

    Previous research has shown that personality traits are associated with self-reported health status in the general population. COPD Assessment Test (CAT) is increasingly used to assess health status such as the impact of chronic obstructive pulmonary disease (COPD) on patients' daily life, but knowledge about the influence of personality traits on CAT score is lacking. The aim of this study was to examine the influence of Big Five personality traits on CAT score and the relation between personality traits and mental symptoms with respect to their influence on CAT score. A sample of 168 patients diagnosed with COPD was consecutively recruited in a secondary care outpatient clinic. All participants completed CAT, NEO Five-Factor Inventory, and Hospital Depression and Anxiety Scale. Multiple linear regression analysis was used to explore the association between personality traits and CAT scores and how this association was influenced by mental symptoms. The personality traits neuroticism, agreeableness and conscientiousness; and the mental symptoms depression and anxiety showed significant influence on CAT score when analysed in separate regression models. Identical R-square (R = 0.24) was found for personality traits and mental symptoms, but combining personality traits and mental symptoms in one regression model showed substantially reduced effect estimates of neuroticism, conscientiousness and anxiety, reflecting the strong correlations between personality traits and mental symptoms. We found that the impact of COPD on daily life measured by CAT was related to personality and mental symptoms, which illustrates the necessity of taking individual differences in personality and mental status into account in the management of COPD.

    The impact of psychosocial factors and personality traits in chronic pain is well established. However, there has been limited literature analyzing the influence of psychological issues in chronic foot and ankle pain. The aim of our study was to identify the association of certain psychosocial factors and personality traits in individuals with chronic painful foot and ankle disorders. Patients with chronic foot and ankle pain were recruited from the specialist foot and ankle clinic. The Eysenck Personality Questionnaire-Revised (EPQ-R), Dysfunctional Attitude Scale (DAS), and Hospital Anxiety Depression (HAD) scale were administered in the form of questionnaires. An age- and sex-matched cohort of healthy volunteers served as the control group. Sample size was determined after power calculation, and a total of 90 participants were recruited with informed consent with 45 participants in each arm. Results were analyzed and statistical analyses were performed using SPSS. Patients with chronic foot and ankle pain had significantly higher neuroticism scores than the control group (P pain (P pain. Clinicians should recognize the influence of these specific psychological issues to provide a more holistic approach to the clinical problem. Level III, case control study. © The Author(s) 2014.

    Full Text Available Recent introduction of hybrid varieties raises the question if bees (Apis mellifera L. contribute as pollinator agents in developing the full yield potential of rapeseed (Brassica napus L.. In order to evaluate the yield achieved by B. napus cv. Artus pollinated by A. mellifera testing was carried out in the district of Freire, La Araucanía Region, Chile. This consisted in isolating or excluding rapeseed plants from pollinators with exclusion cages. Treatments applied were total exclusion (T1, partial exclusion (T2 and free pollination (T0 with a density of 6.5 hives ha-1, in order to determine the following yield components traits: grains per silique, siliques per plant, 1000 grain weight and yield. The experimental design used was randomized complete blocks with three treatments and three replicates. Results obtained show that the parameter least affected by bee intervention was the grains per silique variable. In contrast, siliques per plant and 1000 grain weight parameters presented significant differences, contributing to a yield greater than 5 t ha-1; which represented a figure 50.34% higher than in the treatment without bees. It may be concluded that the inclusion of bees in crops is fully justified as a production tool.La reciente introducción de variedades híbridas plantea la interrogante de la contribución que pueda tener la presencia de abejas (Apis mellifera L. como agentes polinizadores para desarrollar en pleno el potencial productivo del raps (Brassica napus L..

    To evaluate anxiety felt by glaucoma patients. In total, 472 glaucoma patients responded to a questionnaire on anxiety, subjective symptoms, and vision-related quality of life (VR-QOL) associated with glaucoma. Anxiety was evaluated using the State-Trait Anxiety Inventory (STAI), state anxiety (STAI-State) subscale along with our novel questionnaire, assessing visual function and subjective symptoms, specialized for glaucoma. VR-QOL was evaluated using 5 subitems from the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25). Adherence to ophthalmic antiglaucoma agents was confirmed. As indexes of visual function, corrected visual acuity (measured by eye chart), mean deviation (MD) score (measured with static perimetry), and 4 thresholds at the center of vision were determined. Stages were classified according to the Aulhorn Classification. From the STAI-State scores, the prevalence of anxiety in glaucoma patients was evaluated. We analyzed the correlation between the STAI-State and VFQ-25, anxiety, subjective symptoms, adherence, and visual function indexes. In total, 78% of glaucoma patients experienced at least an intermediate level of anxiety. The STAI-State correlated significantly with anxiety and subjective symptoms as measured by our novel questionnaire, particularly for questions "current anxiety about loss of vision" and "current anxiety in life" (r=0.468 and 0.500; both Pglaucoma patients feel anxiety. The STAI-State is correlated with the VR-QOL and anxiety in glaucoma patients, making it useful for understanding the anxiety present in glaucoma patients.

    Full Text Available 404 sarcoidosis and 404 tuberculosis patients were examined in order to detect correlations between clinical manifestations, psychological adaptation and accentuation of personality traits and granulomatous lesions of respiratory organs in case of sarcoidosis and tuberculosis. All patients had subjective and objective examinations and answered the following questionnaires: Schmieschek questionnaire to identify accentuation of personality traits, clinical questionnaire to detect and evaluate neurotic disorders, Taylor Manifest Anxiety Scale to detect the level of anxiety. It has been found out that sarcoidosis patients are characterized both by asymptomatic course of the disease as well as diverse clinical manifestations: pain syndrome, nodal fever, intoxication with expressed general fatigue, respiratory insufficiency. It is combined with stuck, pedant, cycloid, exalted, emotive accentuations of personality traits, with psychological maladaptation as per the scores of autonomic imbalance, neurotic depression, asthenia, with average high level of anxiety. The following is typical of tuberculosis patients: syndrome of bronchial tree lesions and respiratory insufficiency; distymny, demonstrative, excitable, exalted, anxiety-hypochondriac accentuations of personality traits, with psychological maladaptation as per the scores of autonomic imbalance, obsessive-phobic disorders and hysteria; average high level of anxiety. The strong correlation has been found between the degree of symptoms expression, level of anxiety and psychological maladaptation and the type of patient's accentuation of personality traits.

    Full Text Available We report a case of fulminant liver failure resulting in emergent liver transplantation following 3 weeks of nausea, vomiting, and malaise from Jamaican Vomiting Sickness. Jamaican Vomiting Sickness is caused by ingestion of the unripe arils of the Ackee fruit, its seeds and husks. It is characterized by acute gastrointestinal illness and hypoglycemia. In severe cases, central nervous system depression can occur. In previous studies, histologic sections taken from patients with Jamaican Vomiting Sickness have shown hepatotoxicity similar to that seen in Reye syndrome and/or acetaminophen toxicity. We highlight macroscopic and microscopic changes in the liver secondary to hepatoxicity of Ackee fruit versus those caused by a previously unknown sickle cell trait. We discuss the clinical variables and the synergistic hepatotoxic effect of Ackee fruit and ischemic injury from sickled red blood cells, causing massive hepatic necrosis in this patient.

    AIM: To evaluate Quality of life(QoL) in chronic heart failure(CHF) in relation to Neuroticism personality trait and CHF severity.METHODS: Thirty six consecutive, outpatients with Chronic Heart Failure(6 females and 30 males, mean age: 54 ± 12 years), with a left ventricular ejection fraction ≤ 45% at optimal medical treatment at the time of inclusion, were asked to answer the Kansas City Cardiomyopathy Questionnaire(KCCQ) for Quality ofLife assessment and the NEO Five-Factor Personality Inventory for personality assessment. All patients un-derwent a symptom limited cardiopulmonary exercise testing on a cycle-ergometer, in order to access CHF severity. A multivariate linear regression analysis us-ing simultaneous entry of predictors was performed to examine which of the CHF variables and of the person-ality variables were correlated independently to QoL scores in the two summary scales of the KCCQ, namely the Overall Summary Scale and the Clinical Summary Scale.RESULTS: The Neuroticism personality trait score had a significant inverse correlation with the Clinical Sum-mary Score and Overall Summary Score of the KCCQ(r =-0.621, P < 0.05 and r =-0.543, P < 0.001, respec-tively). KCCQ summary scales did not show significant correlations with the personality traits of Extraversion, Openness, Conscientiousness and Agreeableness. Mul-tivariate linear regression analysis using simultaneous entry of predictors was also conducted to determine the best linear combination of statistically significant univari-ate predictors such as Neuroticism, VE/VCO2 slope and VO2 peak, for predicting KCCQ Clinical Summary Score. The results show Neuroticism(β =-0.37, P < 0.05), VE/VCO2 slope(β =-0.31, P < 0.05) and VO2 peak(β = 0.37, P < 0.05) to be independent predictors of QoL.

    Personality traits were assessed by means of the Munich Personality Test (MPT) in 75 Japanese subjects, 27 patients in remission from an episode of moderate to severe primary unipolar depression, with melancholic features during one episode or more of the disorder, in 24 patients in remission from other non-organic mental disorders and in 24 healthy controls. Compared with healthy controls, unipolar depressives displayed decreased Frustration Tolerance and elevated Rigidity as well as a stronger Orientation towards Social Norms. No significant difference was found between patients in remission from either unipolar depression or other mental disorders. However, the increase in Rigidity in comparison with healthy subjects was significant in the depressives only whereas the other patients, in contrast to the depressives, had significantly lower scores in Extraversion than the healthy subjects. Our results in Japanese patients are similar to findings of previous German studies, including two high risk studies, in which the same assessment instrument was used. This suggests that, beyond cultural differences, Rigidity, possibly in combination with a strong Orientation towards Social Norms and a reduced Frustration Tolerance, is a stable vulnerability marker for at least the more severe forms of primary unipolar depression.

    Heterozygote deletions or mutations of pseudoautosomal 1 region (PAR1) encompassing the short stature homeobox-containing (SHOX) gene cause Leri-Weill Dyschondrosteosis (LWD), which is a dominantly inherited osteochondroplasia characterized by short stature with mesomelic shortening of the upper and lower limbs and Madelung deformity of the wrists. SHOX is expressed by both sex chromosomes in males and females and plays an important role in bone growth and development. Clinically, the LWD expression is variable and more severe in females than males due to sex differences in oestrogen levels. Here, we report two familial cases of LWD with a large Xp terminal deletion (approximately 943 kb) of distal PAR1 encompassing the SHOX gene. In addition, the proband had mental retardation which appeared to be from recessive inheritance in the family.

    La trithérapie antirétrovirale a contribué à une baisse considérable de la mortalité liée au VIH. Les causes de décès sont dominées par les infections opportunistes dans les pays en voie de développement et par les maladies cardiovasculaires et les cancers dans les pays développés. L’objectif était de déterminer les causes et les facteurs de risque de décès des patients infectés par le VIH dans le Centre Tunisien. Une étude transversale auprès des patients infectés par le VIH âgés de plus de 15 ans suivis à Sousse et à Monastir entre 2000 et 2014. Le décès était considéré lié au VIH si la cause était un évènement classant SIDA ou s’il était la conséquence d’une infection opportuniste d’étiologie indéterminée avec des CD4 VIH si la cause n’était pas un évènement classant SIDA, et de cause inconnue si aucune information n’était disponible. Deux cents treize patients, 130 hommes (61%) et 83 femmes (39%), d’âge moyen 40±11 ans ont été inclus. Cinquante quatre patients sont décédés, avec une mortalité de 5,4/100 patients-années. La mortalité annuelle a baissé de 5,8% en 2000-2003 à 2,3% en 2012-2014. La survie était de 72% à 5 ans et de 67% à 10 ans. Les décès étaient liés au VIH dans 70,4% des cas. Les causes de décès les plus fréquentes étaient la pneumocystose pulmonaire et la cryptococcose neuroméningée dans 6 cas (11%) chacune. Les facteurs de risque de décès étaient les antécédents d’infections opportunistes, la durée de la trithérapie antirétrovirale VIH en Tunisie. PMID:28292068

    Hemoglobin S is an abnormal protein that induces morphological changes in erythrocyte in low-oxygen conditions. In Mexico, it is reported that up to 13.7% of the population with mutation in one allele are considered asymptomatic (sickle cell trait). The sickle cell trait and diabetes mellitus are conditions that occur together in more than one million patients worldwide. Both diseases possibly produce microvascular changes in retinopathy and acute chest syndrome. The aim of this study was to evaluate the induction of sickle cells in samples of diabetic patients with sickle cell trait to identify altered red cell parameters. We obtained samples of diabetic patients to determine hemoglobin A1c and S; furthermore, red blood cell biometrics data were analyzed. We found that older men with diabetes were susceptible to generate sickle cells and this correlated with reduced red blood cell count and an increase in media cell volume. In samples of women diabetes, there were no differences. We conclude that samples from patients with sickle cell trait and diabetes can cause sickle cells with high frequency in men, with lower red blood cells count and increased mean corpuscular volume as susceptibility parameters.

    Summary Les brûlures électriques par haut voltage sont responsables de gros dégâts tissulaires en immédiat et dans les jours suivant l’accident du fait de la chaleur importante dégagée par effet joule et de la thrombose microvasculaire évolutive. Les pertes de substances du scalp secondaires à ces brûlures nécessitent une couverture par lambeaux vu la destruction du périoste et du calvarium en regard. De juin 1997 à juin 2008, 15 patients ont été traités pour des pertes de substance du scalp secondaires à des brûlures électriques par haut voltage de diamètre allant de 8 à 11 cm et siégeant dans la région tonsurale. Ces patients ont été opérés dans la première semaine suivant l’accident. Les pertes de substance du scalp de taille moyenne secondaires à ces brûlures peuvent être couvertes per primam de façon fiable par des lambeaux locaux axialisés et multiples. Nous relatons l’expérience du Service de Chirurgie Plastique du Centre Hospitalier Universitaire Ibn-Sina, Rabat, Maroc, dans la gestion et la prise en charge de ces brûlures. PMID:22262963

    Introduction Les antivitamines K (AVK), traitement anticoagulant oral le plus largement prescrit, posent un réel problème de santé publique du fait de leur risque iatrogène. L'objectif de cette étude était de préciser le niveau de connaissance des patients sur la gestion de leur traitement par les AVK. Méthodes Il s'est agi d'une enquête transversale descriptive réalisée au CHU-Yalgado Ouédraogo, sur une période de 03 mois : du 1er mars au 31 mai 2012. Un questionnaire a été administré aux patients bénéficiant d'un traitement AVK depuis au moins un mois. Résultats Soixante-dix patients ont été inclus dans l'étude dont 30 hommes. L'âge moyen était de 49 ans ± 16 ans. Les cardiopathies et la maladie thromboembolique veineuse justifiant l'institution du traitement AVK étaient retrouvées respectivement dans 58,6% et 41,4% des cas. Le nom de l'AVK et la raison exacte du traitement étaient connus respectivement dans 91,4% et 67,1% des cas. Plus de la moitié des patients (68,6%) savaient que les AVK rendaient le sang plus fluide. Quarante-six patients (65,7%) citaient l'INR comme examen biologique de surveillance du traitement et seulement 28 patients (40%) connaissaient les valeurs cibles. La majorité des patients ne connaissait pas les risques encourus en cas de surdosage (72,8%) et de sous-dosage (71,4%). Une automédication par anti-inflammatoire non stéroïdien était signalée par 18 patients (25,7%). Les choux (74,3%) et la laitue (62,9%), aliments à consommer avec modération, étaient les plus cités. Conclusion Les connaissances des patients sur la gestion des AVK étaient fragmentaires et insuffisantes pour assurer la sécurité et l'efficacité du traitement. La création d'un programme d'éducation thérapeutique sur les AVK s'avère alors nécessaire. PMID:25870741

    Olfactory identification impairments have been consistently found in schizophrenia patients. However, few previous studies have investigated this in first-episode patients. There are also inconsistent findings regarding olfactory identification ability in psychometrically-defined schizotypy individuals. In this study, we directly compared the olfactory identification ability of first-episode schizophrenia patients with schizotypy individuals. The relationship between olfactory identification impairments and hedonic traits was also examined. Thirty-five first-episode schizophrenia patients, 40 schizotypy individuals as defined by the Chapman's Anhedonia Scales and 40 demographically matched controls were recruited. The University of Pennsylvania Smell Identification Test was administered. Hedonic capacity was assessed using the Temporal Experience of Pleasure Scale (TEPS). The results showed that both the schizophrenia and schizotypy groups showed poorer olfactory identification ability than controls, and the impairment was significantly correlated with reduced pleasure experiences. Our findings support olfactory identification impairment as a trait marker for schizophrenia. Copyright © 2018 Elsevier Inc. All rights reserved.

    Substantial evidence supports an association between childhood maltreatment and suicidal behaviour. However, few studies have examined factors mediating this relationship among patients with unipolar or bipolar mood disorders. Depressive disorder and bipolar disorder (ICD-10-DCR) patients (n=287) from the Helsinki University Psychiatric Consortium (HUPC) Study were surveyed on self-reported childhood experiences, current depressive symptoms, borderline personality disorder traits, and lifetime suicidal behaviour. Psychiatric records served to complement the information on suicide attempts. We examined by formal mediation analyses whether (1) the effect of childhood maltreatment on suicidal behaviour is mediated through borderline personality disorder traits and (2) the mediation effect differs between lifetime suicidal ideation and lifetime suicide attempts. The impact of childhood maltreatment in multivariate models on either lifetime suicidal ideation or lifetime suicide attempts showed comparable total effects. In formal mediation analyses, borderline personality disorder traits mediated all of the total effect of childhood maltreatment on lifetime suicide attempts, but only one fifth of the total effect on lifetime suicidal ideation. The mediation effect was stronger for lifetime suicide attempts than for lifetime suicidal ideation (P=0.002) and independent of current depressive symptoms. The mechanisms of the effect of childhood maltreatment on suicidal ideation versus suicide attempts may diverge among psychiatric patients with mood disorders. Borderline personality disorder traits may contribute to these mechanisms, although the influence appears considerably stronger for suicide attempts than for suicidal ideation.

    Five-Factor Model (FFM) personality traits are related to a wide range of clinical outcome in patients with psychotic disorders. However, it is not sufficiently clear whether psychotic illness, particularly fluctuation in negative symptoms and psychotic relapse, affects personality. The current study examined the 3-year temporal stability of FFM traits in 91 patients with non-affective psychotic disorders with a maximum duration of illness of 10 years and 32 control subjects without a (family member with) a diagnosis of psychotic illness. In patients, change in negative symptoms predicted changes in Neuroticism and (inversely) in Extraversion and Openness. However, when correcting for depressive symptoms, negative symptoms no longer predicted change in any FFM trait. Clinical characteristics, such as psychotic relapse, were also not found to be related to change in FFM traits. Patients showed a slight increase in Conscientiousness levels, the other FFM traits showed mean-level stability. Rank-order stability of the FFM traits was moderate to strong, although weaker for Neuroticism in patients. Our findings indicate that psychotic symptoms exert limited effect on the stability of FFM traits in patients with psychotic disorders. Consistent with general population findings, one should guard against state-trait confusion between Neuroticism/Extraversion and depression. Copyright © 2015 Elsevier Ireland Ltd.

    As opposed to other psychiatric populations, subjects with obsessive-compulsive disorder (OCD) smoke less than the general population. The present study aims at further investigating the relationship between smoking in OCD subjects and personality traits. Sixty-four subjects with OCD were interviewed concerning their smoking habits. Personality traits were evaluated using the Karolinska Scales of Personality, and specific obsessive-compulsive personality traits were elicited through self-report questionnaires. Non-smokers were more easily fatigued, more inclined to worry, more remorseful, less self-confident, less impulsive and became uneasy more frequently when urged to speed up, than smokers with OCD. Additionally, non-smokers fulfilled significantly more obsessive-compulsive personality disorder criteria as compared to the smokers (P < 0.001). We propose a clinical subtype of OCD related to non-smoking, psychasthenia, anxiety, and pronounced obsessive-compulsive personality disorder traits.

    Personality influences an individual's adaptation to a specific job or organization. Little is known about personality trait differences between medical career and specialty choices after graduating from medical school when actually practicing different medical specialties. Moreover, whether personality traits contribute to important career choices such as choosing to work in the private or public sector or with clinical patient contact, as well as change of specialty, have remained largely unexplored. In a nationally representative sample of Finnish physicians (N = 2837) we examined how personality traits are associated with medical career choices after graduating from medical school, in terms of employment sector, patient contact, medical specialty and change of specialty. Personality was assessed using the shortened version of the Big Five Inventory (S-BFI). An analysis of covariance with posthoc tests for pairwise comparisons was conducted, adjusted for gender and age with confounders (employment sector, clinical patient contact and medical specialty). Higher openness was associated with working in the private sector, specializing in psychiatry, changing specialty and not practicing with patients. Lower openness was associated with a high amount of patient contact and specializing in general practice as well as ophthalmology and otorhinolaryngology. Higher conscientiousness was associated with a high amount of patient contact and specializing in surgery and other internal medicine specialties. Lower conscientiousness was associated with specializing in psychiatry and hospital service specialties. Higher agreeableness was associated with working in the private sector and specializing in general practice and occupational health. Lower agreeableness and neuroticism were associated with specializing in surgery. Higher extraversion was associated with specializing in pediatrics and change of specialty. Lower extraversion was associated with not practicing with

    Studies reported a strong genetic correlation between the Big Five personality traits and major depressive disorder (MDD). Moreover, personality traits are thought to be associated with response to antidepressants treatment that might partly be mediated by genetic factors. In this study, we examined whether polygenic scores (PGSs) derived from the Big Five personality traits predict treatment response and remission in patients with MDD who were prescribed selective serotonin reuptake inhibitors (SSRIs). In addition, we performed meta-analyses of genome-wide association studies (GWASs) on these traits to identify genetic variants underpinning the cross-trait polygenic association. The PGS analysis was performed using data from two cohorts: the Pharmacogenomics Research Network Antidepressant Medication Pharmacogenomic Study (PGRN-AMPS, n = 529) and the International SSRI Pharmacogenomics Consortium (ISPC, n = 865). The cross-trait GWAS meta-analyses were conducted by combining GWAS summary statistics on SSRIs treatment outcome and on the personality traits. The results showed that the PGS for openness and neuroticism were associated with SSRIs treatment outcomes at p trait GWAS meta-analyses, we identified eight loci associated with (a) SSRIs response and conscientiousness near YEATS4 gene and (b) SSRI remission and neuroticism eight loci near PRAG1, MSRA, XKR6, ELAVL2, PLXNC1, PLEKHM1, and BRUNOL4 genes. An assessment of a polygenic load for personality traits may assist in conjunction with clinical data to predict whether MDD patients might respond favorably to SSRIs. PMID:29559929

    Objective The aim of this study was to investigate the impacts of personality traits, anxiety, depression and hopelessness levels on quality of life in the patients with breast cancer. Materials and methods The study was performed on 90 patients diagnosed with breast cancer and 90 healthy women. Sociodemographic and Clinical Data Collection Form designed by us, Beck Hopelessness Scale (BHS), Beck Anxiety Scale (BAS), Beck Depression Scale (BDS), Eysenck Personality Inventory (EPI) and Quality of Life Scale–Short Form (SF-36) were administered to patients and to control group. Results The patients with breast cancer were found to indicate higher levels of anxiety and depression, lower levels of quality of life, and higher scores of personality inventory subscales as compared to the healthy control group. In the patient group, it was identified that the quality of life subscale scores were found to be negatively correlated with anxiety, depression, hopelessness and neurotic personality scores; there was a positive correlation between neurotic personality scores and depression, anxiety and hopelessness scores. Conclusions It can be concluded that the breast cancer patients with extraversion personality traits have lower levels of anxiety and depression, keeping their quality of life better, whereas the patients with higher neuroticism scores may have more impaired quality of life. Therefore, the psychiatric evaluation of the breast cancer patients during and after the treatment cannot be ruled out. PMID:29774319

    The Psychopathy Checklist Revised (PCL-R) and Temperament and Character Inventory (TCI) have been used extensively in research of personality disorders; however, no previous study has investigated the relation between psychopathy factors and temperament and character traits in patients with antisocial personality disorder (ASPD). Our aim was to fill this gap in the literature. The PCL-R Factor scores and the TCI temperament and character scores were evaluated in 68 men with ASPD and 65 healthy male controls. The ASPD cases had significantly higher PCL-R Factor 1, Factor 2, and Total scores, as well as significantly higher TCI Novelty Seeking and Harm Avoidance scores, whereas the control group had higher TCI Reward Dependence, Persistence, Self-Directedness, and Cooperativeness scores. Correlation analysis revealed that, in the whole study group, PCL-R Factor 1, Factor 2, and Total scores were positively correlated with Novelty Seeking and Harm Avoidance scores and negatively correlated with Reward Dependence, Persistence, Self-Directedness, and Cooperativeness scores. When each group was analyzed separately, the correlations were not significant. Regression analysis supported the main findings. Our results showed that both PCL-R Factor 1 score, which is claimed to reflect "core psychopathy," and PCL-R Factor 2 score, which reflects criminal behaviors, were positively correlated with Novelty Seeking and Harm Avoidance and were negatively correlated with Reward Dependence in the whole sample. The reduced variance of PCL-R in each group might lead to nonsignificant associations within groups. Without the subjects with severe psychopathy in the present study, it might not be possible to show the association. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND Comorbidity of bipolar disorder and substance use disorder is common. It is difficult to treat bipolar disorder patients with comorbid alcohol use disorder since the disease course is more severe and they have greater difficulties in cognitive functions than those without alcohol use. Whether alcohol negatively affects specific cognitive functions or the deficits are more diffuse in nature is unclear. Alcoholic bipolar patients present with high scores in openness to experience and neuroticism personality traits. Personality to an extent mediates the co-occurrence of substance use in bipolar disorder. Thus, identifying these personality traits in bipolar or substance use disorder patients, will help us to prevent the co-occurrence of the second disorder. The aim of the study is to evaluate the clinical characteristics, personality traits and cognitive functions of patients with bipolar and comorbid alcohol use disorders. MATERIALS AND METHODS A sample of 100 patients, 50 with bipolar and alcohol use disorder (cases and 50 with bipolar disorder (controls attending tertiary care hospital outpatient department at Chennai was selected. Alcohol status was assessed using AUDIT (alcohol use disorder identification test and SADQ (severity of alcohol dependence questionnaire. Personality was assessed using NEO-five factor inventory. Cognition was assessed using frontal lobe assessment battery, Stroop test, DSST (digit symbol substitution test and verbal N back test. RESULTS The cases group had more number of hospitalisations and mixed episodes than control group. They also performed poorer on frontal lobe assessment battery, Stroop test and digit symbol substitution test. Duration of alcohol use was associated positively with total number of hospitalisations and number of episodes. The cases group scored significantly higher on the personality traits of neuroticism and openness to experience. CONCLUSION The study confirmed the higher

    War veterans with PTSD have a high chance of developing major depressive disorder (MDD) at some point, while they can also exhibit increased suicidal tendencies. The primary goal of this research was to investigate whether personality dimensions, including temperament, character, and trait impulsivity, were associated with comorbid MDD, as well as with suicidal ideation in psychiatric patients suffering from combat-related PTSD. The sample consisted of 148 Croatian male war veterans (mean age 49.53 years) treated for PTSD at the National Center for Psychotrauma, Department of Psychiatry, University Hospital Center Zagreb. Fifty-one (34%) of them met ICD-10 diagnostic criteria for current or lifetime MDD, while 97 (66%) were diagnosed with PTSD alone. All the participants were assessed with the M.I.N.I. diagnostic interview and they completed the following battery of self-report instruments: the Beck Depression Inventory-Second Edition (BDI-II), the Suicidal Behaviors Questionnaire-Revised (SBQ-R), the Temperament and Character Inventory-Revised (TCI-R), and the Barratt Impulsiveness Scale-11 (BIS-11). Comparisons between the two clinical groups showed that PTSD+MDD patients were more suicidal and differed with regard to temperament dimensions Harm Avoidance, Reward Dependence and Persistence, character dimension Self-Directedness, and trait impulsivity. In three multivariate regression analyses, it was revealed that character dimension Cooperativeness as well as trait impulsivity were unique predictors of suicidal ideation, while controlling for the influence of sociodemographics, length of treatment and comorbid depression. Combat-related PTSD patients with comorbid depression exhibit increased suicide thoughts and different personality profiles in comparison with those suffering from PTSD alone. Character dimension Cooperativeness and trait impulsivity seem to be uniquely predictive of suicide ideation in this population. Elucidation of individual psychological

    Family environment is a pathogenic factor of borderline personality disorder (BPD). However, the personality traits of patients with BPD and their parents have never been assessed using the same instrument and then examined for relationships. In the present study, we explored the temperament and character traits of BPD patients and their parents to investigate possible interactions. In total, 56 patients with BPD and their parents were evaluated with the Temperament and Character Inventory (TCI) and compared with 53 control families. Discriminant and correlation analyses indicated that subjects with BPD displayed higher levels of novelty seeking, harm avoidance, and self-transcendence and lower levels of self-directedness than control subjects. Their fathers displayed higher levels of novelty seeking and lower levels of persistence and self-directedness, and their mothers displayed lower levels of self-directedness compared with levels in control parents. In BPD families, temperament and character traits displayed high levels of discriminatory power. Novelty seeking in offspring with borderline personality disorder was significantly correlated with their mothers' novelty seeking and their fathers' self-transcendence. Self-directedness in borderline offspring was significantly correlated with both their mothers' and fathers' novelty seeking, and their self-transcendence was significantly correlated with their mothers' novelty seeking and harm avoidance. The different correlational pattern for borderline and control families is discussed. Characteristic personality patterns were found in BPD offspring and in both parents. The relationship between personality traits of borderline offspring and those of their parents may be related to both genetic transmission and family dynamics. Ramifications for treatment are discussed.

  14. Qualitative and quantitative dermatoglyphic traits in patients with breast cancer: a prospective clinical study

    Full Text Available Abstract Background Breast cancer is one of the most extensively studied cancers and its genetic basis is well established. Dermatoglyphic traits are formed under genetic control early in development but may be affected by environmental factors during first trimester of pregnancy. They however do not change significantly thereafter, thus maintaining stability not greatly affected by age. These patterns may represent the genetic make up of an individual and therefore his/her predisposition to certain diseases. Patterns of dermatoglyphics have been studied in various congenital disorders like Down's syndrome and Kleinfelter syndrome. The prints can thus represent a non-invasive anatomical marker of breast cancer risk and thus facilitate early detection and treatment. Methods The study was conducted on 60 histo-pathologically confirmed breast cancer patients and their digital dermatoglyphic patterns were studied to assess their association with the type and onset of breast cancer. Simultaneously 60 age-matched controls were also selected that had no self or familial history of a diagnosed breast cancer and the observations were recorded. The differences of qualitative (dermatoglyphic patterns data were tested for their significance using the chi-square test, and for quantitative (ridge counts and pattern intensity index data using the t- test. Results It was observed that six or more whorls in the finger print pattern were statistically significant among the cancer patients as compared to controls. It was also seen that whorls in the right ring finger and right little finger were found increased among the cases as compared to controls. The differences between mean pattern intensity index of cases and controls were found to be statistically significant. Conclusion The dermatoglyphic patterns may be utilized effectively to study the genetic basis of breast cancer and may also serve as a screening tool in the high-risk population. In a developing

    A 14-year-old black boy with sickle cell trait, who sustained a traumatic hyphema, developed moderately elevated intraocular pressure that failed to respond to carbonic anhydrase inhibitors and osmotic agents. On the tenth postinjury day, a sudden increased cupping of the optic disc and partial central retinal artery obstruction caused painless loss of vision. Reversal of the cupping, the retinal ischemia, and the intraocular pressure was documented following anterior chamber paracentesis, and visual acuity returned to 6/6. Pathophysiology of the posterior ischemia is discussed. This case documents the potentially debilitating course of traumatic hyphema in "benign" sickle cell trait and its avoidance with proper management. The authors endorse recent suggestions for careful observation of any sickle cell patient with traumatic hyphema, and recommend anterior chamber paracentesis, supplemental oxygen, and avoidance of osmotic agents, if secondary glaucoma develops following the initial trauma.

    [Correction Notice: An Erratum for this article was reported in Vol 29(11) of Psychological Assessment (see record 2016-56886-001). In the article, several values were reversed and the mean was misreported in Table 2. The corrected table is present in the erratum.] Pathological narcissism represents a clinically relevant, albeit controversial personality construct, with multiple conceptualizations that are operationalized by different measures. Even in the recently published Diagnostic and Statistical Manual for Mental Disorders-Fifth Edition (DSM-5), 2 different views of narcissistic personality disorder (NPD) are formulated (i.e., Section II and Section III). The DSM-5 Section III alternative PD model diagnosis of NPD is based on self and interpersonal dysfunction (Criterion A) and a profile of maladaptive personality traits (Criterion B), specifically elevated scores on Attention Seeking and Grandiosity. Given the diversity of conceptualizations of pathological narcissism, we evaluated the convergences and divergences in DSM-5 trait profiles characterizing multiple measures of narcissism in a clinical sample of 278 consecutively admitted Italian psychotherapy patients. Patients were administered the Italian versions of the Personality Inventory for DSM-5 (PID-5) and 4 measures of NPD, (a) the Narcissistic Personality Inventory (NPI); (b) the NPD scale of the Personality Diagnostic Questionnaire-4+; (c) the Structured Clinical Interview for Axis II Personality Disorders, Version 2.0 (SCID-II) as an observer-rated measure of NPD; and (d) the Pathological Narcissism Inventory (PNI). Multiple regression analyses showed that PID-5 traits explained from 13% to more than 60% of the variance in the different NPD measures. Attention Seeking was consistently associated with all measures of NPD, whereas Grandiosity was associated with some of the NPD measures. All measures of NPD were also significantly related to additional DSM-5 maladaptive traits. (PsycINFO Database

    Full Text Available ABSTRACT BACKGROUND The presence of psychiatric symptoms, anger, and personality characteristics are factors that affect the quality of life of newly diagnosed digestive system cancer patients. OBJECTIVE This study aims to identify which stable characteristics of the individual’s personality interfere with quality of life, even when reactive emotional characteristics of falling ill are controlled. METHODS A cross-sectional study was performed at the Oncology Clinic ( Hospital das Clínicas , Marília/SP, Brazil, in which 50 adult patients with digestive system cancer and diagnosed less than 6 months answered the State-Trait Anger Expression Inventory, Temperament and Character Inventory, Hospital Anxiety and Depression Scale and WHOQOL-BREF. Multiple regression was performed to verify if quality of life was related to stable characteristics of the subject’s personality (anger trait, temperament and character after controlling to the transient emotional aspects (anger state, psychiatric symptoms. RESULTS The quality of life psychological health score was higher in presence of self-directedness character and reward dependence temperament and quality of life environment score was higher in presence of self-directedness character and lower in presence of harm avoidance temperament. CONCLUSION The psychological well-being and the adaptive needs to the environment that favoring a better quality of life were reinforced mainly by the self-directedness character; which means that patients more autonomous cope better with the disease. On the other hand, the harm avoidance temperament (meaning the patient has fear of aversive situations impaired the adaptive capacity to deal with the changes of the day-to-day imposed by the disease. Understanding these personality traits is important to the health professionals drive the patient to more successful treatment.

This study aimed to find connections between suicidality and self-stigma, hope, and personality traits in patients with schizophrenia. Methods: Forty-eight stabilized outpatients with schizophrenia attended this cross-sectional study. Patients were diagnosed by the Mini International Neuropsychiatric Interview (MINI using the ICD-10 research diagnostic criteria. The assessments included Positive and Negative Syndrome Scale, objective and subjective Clinical Global Impression, Liebowitz Social Anxiety Scale, Beck Depression Inventory-second edition, Internalized Stigma of Mental Illness, the Temperament and Character Inventory, and Adult Dispositional Hope Scale. Results: The individual rate of suicidality (suicidal index from MINI strongly positively correlated with self-stigma, level of depression, social anxiety, and harm-avoidance, and negatively correlated with hope, self-directedness, and stigma resistance. Conclusion: Individuals with additional symptoms of depression, social anxiety, trait-like anxiety, and self-stigma should be carefully monitored for suicidal ideation. On the opposite side, patients with sufficient hope, self-esteem, and goal-directed attitudes are less likely to have suicidal thoughts and may potentially be role models in group rehabilitation programs, motivating more

    Full Text Available The estimate of the genetic parameters associated with processing (fresh-cut traits, including root length (RL, is crucial for carrot breeding programs in tropical areas. The cultivar Alvorada is an important germplasm due to its resistance to nematodes, leaf blight, heat-tolerance, and high carotenoid content. Seventy-four 'Alvorada' half-sib progenies were evaluated during the summer of 2005 in the Federal District, Brazil, in a randomized complete block design with three replications. Thirteen competitive plants in each block were randomly selected and evaluated and/or classified for RL and for number of leaves (NL, leaf length (LL, root tip type (RT, root mass (RW, crown shape (CS, root diameter (RD, and xylem diameter (XD. The Pearson's correlation coefficients and the heritability values were estimated for all traits. The path analysis was also used considering the RL trait as dependent variable. The heritability for RL ranged from 12 to 44%. For the other traits, the values ranged from 3% (RD to 79% (LL. Phenotypic and genotypic correlations among all traits were low to intermediate. Path analysis indicated positive direct relationship between RL and RW, whereas RD and XD displayed negative direct effect on RL. Longer roots had narrow diameter and narrow XD. Recurrent selection based upon either half-sib or S1 families would be more effective than mass phenotypic recurrent selection in increasing RL and to develop populations expressing multiple desirable processing traits in tropical-adapted carrot germplasm.A estimativa de parâmetros genéticos associados com caracteres de processamento industrial, incluindo comprimento de raiz (RL, é crucial para programas de melhoramento de cenoura para áreas tropicais.

    This study aimed to investigate the effect of temperament and character traits on perceived social support and quality of life in patients with epilepsy (PWE). Fifty-two PWE and 54 healthy controls were included in this study. Demographics and clinical data were recorded. Temperament and Character traits were investigated using Temperament and Character Inventory (TCI), Perceived Social Support was evaluated by Multidimensional Scale of Perceived Social Support Scale (MSPSS), and quality of life was assessed using a 36-Item Short-Form Health Survey (SF-36). Participants also completed the Hospital Anxiety Depression Scale (HADS). TCI and MSPSS scores showed no significant difference between the groups (p>0.05). Mental and physical subscales of SF-36 were significantly lower in PWE than the controls (p=0.012, p=0.020, respectively). Multiple linear regression analysis indicated that Reward Dependence and Cooperativeness were independent predictors for perceived social support, and Persistence score was an independent predictor for the physical subscale of SF-36 even after adjustment for confounding background variables (plife in PWE. Thus, an evaluation of temperament and character traits may play a significant role in preventing negative effects on perceived social support and quality of life in PWE.

    Full Text Available The occurrence of HTLV-I/II and HIV-1 coinfections have been shown to be frequent, probably in consequence of their similar modes of transmission. This paper presents the prevalence of coinfection of HTLV among HIV-1 infected and AIDS patients in Belém, State of Pará, Brazil. A group of 149 patients attending the AIDS Reference Unit of the State Department of Health was tested for the presence of antibodies to HTLV-I/II using an enzyme immunoassay and the positive reactions were confirmed with a Western blot that discriminates between HTLV-I and HTLV-II infections. Four patients (2.7% were positive to HTLV-I, seven (4.7% to HTLV-II and one (0.7% showed an indeterminate pattern of reaction. The present results show for the first time in Belém not only the occurrence of HTLV-II/HIV-1 coinfections but also a higher prevalence of HTLV-II in relation to HTLV-I. Furthermore, it also enlarges the geographical limits of the endemic area for HTLV-II in the Amazon region of Brazil.

    A water budget for the Par Pond hydrologic system was established in order to estimate the rate of groundwater influx to Par Pond. This estimate will be used in modeling exercises to predict Par Pond reservoir elevation and spillway discharge in the scenario where Savannah River water is no longer pumped and discharged into Par Pond. The principal of conservation of mass was used to develop the water budget, where water inflow was set equal to water outflow. Components of the water budget were identified, and the flux associated with each was determined. The water budget was considered balanced when inflow and outflow summed to zero. The results of this study suggest that Par Pond gains water from the groundwater system in the upper reaches of the reservoir, but looses water to the groundwater system near the dam. The rate of flux of groundwater from the water table aquifer into Par Pond was determined to be 13 cfs. The rate of flux from Par Pond to the water table aquifer near the dam was determined to be 7 cfs

    Personality is considered as an important aspect that can affect symptoms and social function in persons with schizophrenia. The personality questionnaire Swedish universities Scales of Personality (SSP) has not previously been used in psychotic disorder. To investigate if SSP has a similar internal consistency and factor structure in a psychosis population as among healthy controls and if patients with psychotic disorders differ from non-psychotic individuals in their responses to the SSP. Patients with psychotic disorders (n = 107) and healthy controls (n = 119) completed SSP. SSP scores were analyzed for internal consistency and case-control differences by Cronbach's alfa and multiple analysis of covariance, respectively. Internal consistencies among patients were overall similar to that of controls. The patients scored significantly higher in seven (Somatic trait anxiety, Psychic trait anxiety, Stress susceptibility, Lack of assertiveness, Detachment, Embitterment, Mistrust) and lower in three (Physical trait aggression, Verbal trait aggression, Adventure seeking) of the 13 scales of the inventory. In three scales (Impulsiveness, Social desirability and Trait irritability) there was no significant difference between the scoring of patients and healthy controls. The reliability estimates suggest that SSP can be used by patients with psychotic disorders in stable remission. Patients score higher on neuroticism-related scales and lower on aggression-related scales than controls, which is in accordance with earlier studies where other personality inventories were used.

    End-stage chronic kidney disease (CKD) requiring dialysis affects the quality of life sometimes more severely than other chronic diseases, such as rheumatoid arthritis, heart failure, coronary artery disease, and chronic obstructive pulmonary disease, exerting a negative effect on the energy and vitality levels, limiting social interactions, and hindering psychic health. To evaluate the quality of life of patients with CKD on hemodialysis in a public Brazilian Amazonian hospital. Data were collected through interview based on the Brazilian version of the SF-36 questionnaire. The study was conducted on 50 patients (mean age, 48 ± 16 years; mean hemodialysis time, 3 ± 2.9 years). The most affected domain was role limitations due to physical health, with a mean score of 36 ± 36, and 58% of the patients in the lowest quartile, while mental health and social functioning were relatively preserved, with most patients in the highest quartile. Men obtained poorer scores than women did for role limitations due to physical health and vitality. Age correlated negatively with physical functioning. Patients on hemodialysis for more than one year had better scores in the social functioning domain, with a positive correlation between dialysis time and physical functioning. The domains assessed were globally impaired in the population studied, especially regarding role limitations due to physical health, suggesting that chronic disease with prolonged treatment has a negative influence on those domains.

    Post-traumatic stress disorder (PTSD) and depression are common after cardiac surgery. Lifetime stress exposure and personality traits may influence the development of these psychiatric conditions. Self-reported rates of PTSD and depression and potential determinants (i.e., trait anxiety and stress exposure) were established 1.5 to 4 years after cardiac surgery. Data was available for 1125 out of 1244 (90.4%) participants. Multivariable linear regressions were conducted to investigate mediating and/or moderating effects of trait anxiety on the relationship between stress exposure, and PTSD and depression. Pre-planned subgroup analyses were performed for both sexes. PTSD and depression symptoms were present in 10.2% and 13.1% of the participants, respectively. Trait anxiety was a full mediator of the association between stress exposure and depression in both the total cohort and female and male subgroups. Moreover, trait anxiety partially mediated the relationship between stress exposure and PTSD in the full cohort and the male subgroup, whereas trait anxiety fully mediated this relationship in female patients. Trait anxiety did not play a moderating role in the total patient sample, nor after stratification on gender. The unequal distribution of male (78%) and female patients (22%) might limit the generalizability of our findings. Furthermore, risk factors were investigated retrospectively and with variable follow-up time. In cardiac surgery patients, trait anxiety was found to be an important mediator of postoperative PTSD and depression. Prospective research is necessary to verify whether these factors are reliable screening measures of individuals' vulnerability for psychopathology development after cardiac surgery.

    Full Text Available Studies reported a strong genetic correlation between the Big Five personality traits and major depressive disorder (MDD. Moreover, personality traits are thought to be associated with response to antidepressants treatment that might partly be mediated by genetic factors. In this study, we examined whether polygenic scores (PGSs derived from the Big Five personality traits predict treatment response and remission in patients with MDD who were prescribed selective serotonin reuptake inhibitors (SSRIs. In addition, we performed meta-analyses of genome-wide association studies (GWASs on these traits to identify genetic variants underpinning the cross-trait polygenic association. The PGS analysis was performed using data from two cohorts: the Pharmacogenomics Research Network Antidepressant Medication Pharmacogenomic Study (PGRN-AMPS, n = 529 and the International SSRI Pharmacogenomics Consortium (ISPC, n = 865. The cross-trait GWAS meta-analyses were conducted by combining GWAS summary statistics on SSRIs treatment outcome and on the personality traits. The results showed that the PGS for openness and neuroticism were associated with SSRIs treatment outcomes at p < 0.05 across PT thresholds in both cohorts. A significant association was also found between the PGS for conscientiousness and SSRIs treatment response in the PGRN-AMPS sample. In the cross-trait GWAS meta-analyses, we identified eight loci associated with (a SSRIs response and conscientiousness near YEATS4 gene and (b SSRI remission and neuroticism eight loci near PRAG1, MSRA, XKR6, ELAVL2, PLXNC1, PLEKHM1, and BRUNOL4 genes. An assessment of a polygenic load for personality traits may assist in conjunction with clinical data to predict whether MDD patients might respond favorably to SSRIs.

    The study aimed to evaluate outcomes of epiretinal membrane (ERM) peeling in patients with asteroid hyalosis (AH) and to compare them with those from controls without AH. This is a retrospective matched cohort study of 1,104 consecutive patients who underwent surgery for ERM between January 2004 and February 2014. Patients with AH were included in the study group and were matched for preoperative visual acuity, age, gender, date of surgery, and axial length with control patients without AH selected from the same cohort. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) on optical coherence tomography were measured at baseline and postoperatively with a minimum follow-up period of 12 months. A total of 44 patients were included in the AH group and 44 in the control group. The mean initial BCVA was 0.53 ± 0.21 LogMAR for the AH group vs. 0.49 ± 0.20 LogMAR for the control group, and the mean initial CMT was 419 ± 74 vs. 423 ± 75 µm, respectively. During the follow-up, no significant difference was found regarding the final BCVA at 6 months (0.23 ± 0.14 vs. 0.24 ± 0.17) LogMAR (p = 0.87) and 12 months (0.16 ± 0.09 vs. 0.17 ± 0.12) LogMAR (p = 0.92), despite a tendency toward slower visual recovery for the AH group at 1 month, with a mean BCVA of 0.36 ± 0.12 vs. 0.28 ± 0.18 LogMAR (p = 0.08). No difference was found regarding the progression of CMT at 1.6 and 12 months with a mean CMT of 396 ± 47 vs. 378 ± 55 µm (p = 0.39), 356 ± 39 vs. 365 ± 41 µm (p = 0.48), and 349 ± 68 vs. 352 ± 53 µm (p = 0.87), respectively. Vitrectomy with ERM peeling in patients with AH was beneficial and showed similar functional and anatomical outcomes in both groups. AH does not seem to affect visual improvement or the complication rate after ERM peeling. Therefore, the indications for vitrectomy in case of ERM should not be prompted by the presence of AH. © 2017 S. Karger AG, Basel.

    It is unknown whether direct repair (DR) of pars defect after lumbar discectomy (LD) for patients with lumbar disc herniation (LDH) and spondylolysis leads to better outcomes than LD alone. The aim was to compare two surgical methods, LD alone and LD with DR, for LDH patients with spondylolysis at a nearby lumbar segment. This was a retrospective comparative study. This study enrolled 89 patients who were diagnosed with LDH and spondylolysis at the same or adjacent lumbar segment and were followed up for at least 1 year. The primary outcome was pain intensity of the lower back and lower extremities as measured with visual analog scale. Secondary outcomes included clinical outcomes as assessed with the Oswestry Disability Index and the 12-item short form health survey, radiologic outcomes as assessed with the gap distance and the union rate at the pars defect, surgical outcomes, and complications. Enrolled patients were classified into two groups: LD alone (Group A, 48 patients) and LD with DR (Group B, 41 patients). Pain intensity of the lower back and lower extremities and clinical outcomes were significantly improved 1 year after surgery compared with preoperative scores. However, the scores in the group receiving LD alone steadily worsened during follow-up, whereas the scores in the group receiving LD with DR did not deteriorate over time. The difference in the gap distance of the pars defect between baseline and 1 year after surgery was significantly different between the groups. The fusion rate of the pars defect was 59% (24/41). With the exception of surgical time, which was longer in Group B, surgical outcomes and complications did not differ significantly between the groups. At the 1-year follow-up, DR after LD was associated with better outcomes for LDH with spondylolysis than LD alone. Copyright © 2015 Elsevier Inc. All rights reserved.

    Marfan syndrome is a genetic disease, presenting with dysfunction of connective tissues leading to lesions in the cardiovascular and skeletal muscle system. Within these symptoms, the most typical is weakness of the connective tissue in the aorta, manifesting as aortic dilatation (aneurysm). This could, in turn, become annuloaortic ectasia, or life-threatening dissection. As a result, life-saving and preventative cardiac surgical interventions are frequent among Marfan syndrome patients. Aortic aneurysm could turn into annuloaortic ectasia or life-threatening dissection, thus life-saving and preventive cardiac surgical interventions are frequent among patients with Marfan syndrome. We hypothesized that patients with Marfan syndrome have different level of anxiety, depression and satisfaction with life compared to that of the non-clinical patient population. Patients diagnosed with Marfan syndrome were divided into 3 groups: those scheduled for prophylactic surgery, those needing acute surgery, and those without need for surgery (n = 9, 19, 17, respectively). To examine the psychological features of the patients, Spielberger's anxiety (STAI) test, Beck's Depression questionnaire (BDI), the Berne Questionnaire of Subjective Well-being, and the Satisfaction with Life scale were applied. A significant difference was found in trait anxiety between healthy individuals and patients with Marfan syndrome after acute life-saving surgery (p Marfan syndrome patients was 48.56 (standard deviation (SD): 5.8) as compared to the STAI population mean score of 43.72 (SD: 8.53). No difference was found between groups on the BDI (p > 0.1). Finally, a significant, medium size effect was found between patient groups on the Joy in Living scale (F (2.39) = 3.51, p = 0.040, η 2  = 0.15). Involving psychiatric and mental-health care, in addition to existing surgical treatment interventions, is essential for more successful recovery of patients with Marfan syndrome.

    Suicide and mood disorders (especially major depressive disorder (MDD) and bipolar affective disorder (BD)) represent a significant global health burden. Major depressive disorder and bipolar affective disorder have been associated with increased risk for suicide. Some specific suicide risk factors might be found in underlying individual personality traits. Specific personality features may predispose an individual to mood disorders (MDD or BD) hence increased suicide risk. The specificity of this research is in the assessment of personality features during the acute phase of illness immediately after suicide attempt which resulted in psychiatric inpatient treatment. The study included 119 unrelated Caucasian participants with MDD-severe depressive episode without psychotic symptoms (MDD) and BD-severe depressive episode without psychotic symptoms (BD-sDE). Both groups of patients with MDD and BD-sDE were divided into the suicide attempters and non-suicidal group. The diagnoses of the severe depressive episode without psychotic symptoms in major depressive disorder (MDD; F32.2) and bipolar disorder (BD-sDE; F31.4) were made according to ICD-10 (WHO 1992) diagnostic criteria. Methods of suicide attempts were also assessed according to ICD-10 and a self-report questionnaire, the Temperament and Character Inventory (TCI) was applied. The participants who exhibited suicide attempt had significantly higher scores on harm-avoidance (HA) (psuicidal attempt had significantly lower scores on self-directedness (SD) (psuicide attempt may have some significantly different personality traits than non-suicidal patients with mood disorders. The combination of high harm-avoidance (HA) and low self-directedness (SD) may be specific for depressive episode while the combination of high HA, novelty-seeking (NS), and self-transcendence (ST) with low SD may be related to suicide attempts during the depressive episode in bipolar disorder. The novelty-seeking (NS), self-transcendence (ST

    For a few years, the CERN Library has been receiving books from the University of Hanover sent via Avignon, at least that's what it says on the envelope. Such a detour would mean that parcels were travelling 720 km more than the distance separating Geneva and Hanover, which would be a very strange state of affairs. The explanation lies in a spelling mistake. The sender has been stamping parcels with a stamp that says "Par Avignon prioritaire" (first-class via Avignon) instead of "Par Avion prioritaire" (First Class Air Mail), a source of much amusement to the librarians!

    Klinefelter's syndrome (KS) is associated with specific neurobehavioral features and personality traits. The aim of our study was to investigate fluid intelligence, personality traits and personality disorders (PD) and possible correlations with testosterone in a cohort of adult KS patients. We analyzed 58 adult KS patients with the classic 47, XXY karyotype. The Structured Clinical Interview for axis II disorders was used to assess DSM IV personality disorders. Personality traits were assessed using MMPI-2. Fluid intelligence was tested by using Raven's Standard Progressive Matrices (SPM) Test. Testosterone blood concentration was measured by CMIA. PD prevalence was 31%. Four altered MMPI scales (Social Responsibility, Dominance, Ego Strength and Repression) were found in more than 40% of patients. Overcontrolled hostility and MacAndrew Alcoholism Scale-Revised scales were altered in the PD- group only. Biz-Odd Thinking and Post-Traumatic Stress Disorder scale were associated with the presence of personality disorder. The raw SPM score was 44 ± 10.8 without any significant correlation with testosterone. No significant difference in mean age, SPM raw score and MMPI score was observed between eugonadal, hypogonadal and treated patients. Most KS patients had average fluid intelligence. PD prevalence was higher than in the general population. Testosterone was not correlated with fluid intelligence, personality traits or PD, but a reduction in marital distress was observed in treated patients. This could suggest that testosterone therapy can improve physical symptoms and this effect could also improve relationship abilities and wellness awareness.

  6. A Novel SCN5A Mutation in a Patient with Coexistence of Brugada Syndrome Traits and Ischaemic Heart Disease

    Full Text Available Brugada syndrome (BrS is a primary electrical heart disease, which can lead to sudden cardiac death. In older patients with BrS, the disease may coexist with ischaemic heart disease (IHD and recent studies support a synergistic proarrhythmic effect of the two disease entities. We report a case that illustrates this. The index patient was a middle-aged patient with BrS traits, IHD, and aborted sudden cardiac death. Mutation analysis discovered a novel mutation P468L in the NaV1.5 sodium channel. Surprisingly, voltage-clamp experiments on the wild-type and mutant NaV1.5 channels expressed in HEK cells revealed no functional effect of the mutation. In a patient like ours, the distinction between IHD and BrS as the cause of an aborted sudden cardiac death is hard to establish and mounting evidence shows that coexistence of the two may have a synergistic proarrhythmic effect.

  7. Monitoring of chemotherapy successfulness of Platina/Taxol chemotherapy protocol by using determination of serum urokinase plasminogen activator (uPA and soluble urokinase plasminogen activator receptor (suPAR in patients with ovarian carcinoma FIGO II

    Full Text Available In about 70% of cases, ovarian carcinoma has been diagnosed at an advanced stage. Invasion and metastasis of solid tumors request protease activity resulting in basal membrane destruction and surrounding matrix. In that process, urokinase plasminogen activator (uPA and its receptor, urokinase plasminogen activator receptor (suPAR play a key role, that via plasmin activation lead to basal membrane and matrix degradation in surrounding of the tumor, enable to its invasion and metastasis. Determination of serum concentration of those tumor markers can be useful in preoperative as well as in postoperative period. Their serum concentrations in ovarian cancer patients may help in good monitoring of remission or progression during chemotherapy treatment. In late 1950s and eariy 1960s, when it was found out that malignant ovarian tumors were chemosensitive, their chemotherapy treatment has begun. In the beginning it was used only mono-therapy, and by discovering new cytostatics it was replaced by poly-chemotherapy. Now days, in the therapy of advanced stages of ovarian carcinoma combination of cisplatine or carboplatine with paclitaxel is considering as standard treatment. Aim of this study was to determine serum uPA, suPAR and CEA in FIGO II and III patients with different histo-logical type (serous, mucinous, clear cell tumor before and after PT chemotherapy protocol during following three cycles. In this prospective study we have analyzed 17 patients with ovarian carcinoma, those have been after surgery treated by chemotherapy. Serum levels of uPA and suPAR have been determined by ELISA-test (Imubind uPA, Imubind uPAR, American Diagnostica, and CEA by OPUS Imunoassay method. Results of this study have shown that uPA, suPAR and CEA met criteria for prognostic markers for monitoring of successful-ness of platina/taxol chemotherapy protocol for serous, mucinous and clear cell tumor FIGO II and III stage of ovarian carcinoma.

    Background The impact of psychological factors is often taken into account in the evaluation of quality of life. However, the effect of optimism and trait anxiety remains controversial and they are rarely studied simultaneously. We aimed to study the effect of this factor on health-related quality of life (HRQOL) of patients after a hospitalization in relation with their chronic disease. Methods Using cross-sectional data from the SATISQOL cohort, we conducted a multicentric study, including patients hospitalized for an intervention in connection with their chronic disease. Six months after hospitalization, patients completed a generic HRQOL questionnaire (SF-36), and the STAI and LOT-R questionnaires to evaluate optimism and trait anxiety. We studied the effect of each trait on HRQOL separately, and simultaneously, taking account of their interaction in 3 models, using an ANOVA. Results In this study, 1529 patients were included in three participating hospitals and there existed wide diversity in the chronic diseases in our population. The HRQOL score increased for all dimensions of SF36 between 15,8 and 44,5 when the level of anxiety decreased (p optimism (optimism on HRQOL. In the model 3, assessing the effect of both anxiety and optimism on HRQOL, and their interaction, the HRQOL score for all dimensions of the SF36 increased when the level of anxiety decreased (p optimism (p optimism was significant for the Social Functioning dimension (p = 0.0021). Conclusions Optimism and trait anxiety appeared to be significantly correlated with HRQOL. Furthermore, an interaction existed between the trait anxiety and optimism for some dimensions of SF36. Contrary to optimism, it seems essential to evaluate trait anxiety in future studies about HRQOL, since it could represent a confounding factor. PMID:23914779

  9. Protease-activated receptor (PAR2, but not PAR1, is involved in collateral formation and anti-inflammatory monocyte polarization in a mouse hind limb ischemia model.

    Directory of Open Access Journals (Sweden)

    Lisa G van den Hengel

    Full Text Available AIMS: In collateral development (i.e. arteriogenesis, mononuclear cells are important and exist as a heterogeneous population consisting of pro-inflammatory and anti-inflammatory/repair-associated cells. Protease-activated receptor (PAR1 and PAR2 are G-protein-coupled receptors that are both expressed by mononuclear cells and are involved in pro-inflammatory reactions, while PAR2 also plays a role in repair-associated responses. Here, we investigated the physiological role of PAR1 and PAR2 in arteriogenesis in a murine hind limb ischemia model. METHODS AND RESULTS: PAR1-deficient (PAR1-/-, PAR2-deficient (PAR2-/- and wild-type (WT mice underwent femoral artery ligation. Laser Doppler measurements revealed reduced post-ischemic blood flow recovery in PAR2-/- hind limbs when compared to WT, while PAR1-/- mice were not affected. Upon ischemia, reduced numbers of smooth muscle actin (SMA-positive collaterals and CD31-positive capillaries were found in PAR2-/- mice when compared to WT mice, whereas these parameters in PAR1-/- mice did not differ from WT mice. The pool of circulating repair-associated (Ly6C-low monocytes and the number of repair-associated (CD206-positive macrophages surrounding collaterals in the hind limbs were increased in WT and PAR1-/- mice, but unaffected in PAR2-/- mice. The number of repair-associated macrophages in PAR2-/- hind limbs correlated with CD11b- and CD115-expression on the circulating monocytes in these animals, suggesting that monocyte extravasation and M-CSF-dependent differentiation into repair-associated cells are hampered. CONCLUSION: PAR2, but not PAR1, is involved in arteriogenesis and promotes the repair-associated response in ischemic tissues. Therefore, PAR2 potentially forms a new pro-arteriogenic target in coronary artery disease (CAD patients.

    Impulse control disorders (ICDs) are clinically relevant in Parkinson disease (PD) patients, with an established association with PD medication. Aim of our study was to study whether the increased frequency of pathological gambling (PG), reported in subgroups of PD patients, is related to specific personality tracts additional to dopaminergic medications. Thirty-seven PD patients with a personal history of PG where enrolled. Twenty one PD patients, matched for disease and dopaminergic therapy, never experiencing PG, were enrolled as controls. All subjects were tested with the Minnesota Multiphasic Inventory Personality scales (MMPI-2). Our data showed that PD group with PG exhibited significantly higher mean values of the three validity scales in comparison to the non-PG-PD group, demonstrating an higher tendency to lie. Content scales showed a significant increase of cynicism and bizarre ideation scales score in the PG-PD group, not exhibiting pathological values at the validity scales, (p: 0.02) in comparison to non-PG PD patients. According to our results, PG seems to be associated with precise personality tracts. Personality profiles of cluster A personality disturbances - Axys 2 according with DSM-5 TR (paranoid type) at MMPI-2 might be a warning index helpful in selecting dopaminergic treatment, to avoid subsequent ICDs appearance.

    Purpose To analyze the prognostic factors of loco regional control (L.R.C.), specific survival (S.S.) and sphincter conservation (S.C.) of patients treated by curative and conservative irradiation for an epidermoid cancer of anal canal in our institution. Patients and methods From 1976 to 2005, 286 patients (pts) were treated by exclusive radiotherapy (180 pts) or chemo-radiotherapy (106 pts) followed by a brachytherapy boost (233 pts) or external beam radiotherapy boost (24 pts). Forty-three pts were stage I, 154 stage II, 31 stage IIIA and 53 stage IIIB. Results The mean follow-up was 65 months (range: 1.3-250 months). The 5-years-overall survival and S.S. rates were 66.4% and 78.1% respectively. In multivariate analysis, tumor size (? 40 mm) [R.R. = 2.1], node involvement (R.R. = 2.4), and poor response (< 75%) to first course irradiation [R.R. = 1.9], local relapse (R.R. = 4.5) and distant metastases were factors of poor prognosis for S.S.. Five-years-L.R.C. were 71.5% (88% for stage I, 69% for stage II, 77%, for stage IIIA and 60% for stage IIIB). Prognosis factors of L.C.R. were tumor size (R.R. = 2.5), response to first course of irradiation (R.R. = 2.9). S.C. was 71% at 5 years. Prognosis factors of S.C. were tumor size (R.R. = 1.9) and response to first course of irradiation (R.R. = 2.4). Conclusion The results of this series are similar to those of the literature. As well as initial tumor extension, response to first course of irradiation was found as prognostic factor on L..R., S.S., S.C.. Our results are similar to other series and brachytherapy seems not to be deleterious. Its impact to local control remains to be evaluated. (authors)

    Earlier studies indicated that personality characteristics contribute to symptomatic outcome in patients with psychotic disorders. The aim of the present study was to further explore this connection by examining the relationship between the Five-Factor Model (FFM) personality traits and a dimensional liability for psychosis. FFM traits according to the NEO-FFI and levels of subclinical psychotic symptoms according to the CAPE were assessed in 217 patients with psychotic disorders, 281 of their siblings and 176 healthy controls. Psychotic symptoms according to the PANSS were assessed in the patient group. Patients differed from siblings and controls on four of the five FFM traits, all but Openness. Siblings reported higher levels of Neuroticism than controls, but lower levels than patients. Particularly lower Agreeableness, and to a lesser degree, higher Neuroticism and lower Extraversion were associated with more severe symptoms in patients. Furthermore, higher Neuroticism and higher Openness were associated with higher levels of subclinical psychotic experiences in all three groups. Associations were strongest in patients. Our findings suggest that levels of Neuroticism increase with the level of familial risk for psychosis. Levels of Openness may reflect levels of impairment that distinguish clinical from subclinical symptomatology. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Taking into account the impact of MPM on emotional functioning and wellbeing, this study aimed to evaluate the quality of life and personality traits in patients with MPM and their first-degree caregivers through the World Health Organization Quality of Life–BREF (WHOQOL-BREF and the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF. The sample was composed of 27 MPM patients, 55 first-degree relatives enrolled in Casale Monferrato and Monfalcone (Italy, and 40 healthy controls (HC. Patients and relatives reported poorer physical health than the HC. Patients had a higher overall sense of physical debilitation and poorer health than relatives and the HC, more numerous complaints of memory problems and difficulties in concentrating, and a greater belief that goals cannot be reached or problems solved, while often claiming that they were more indecisive and inefficacious than the HC. First-degree relatives reported lower opinions of others, a greater belief that goals cannot be reached or problems solved, support for the notion that they are indecisive and inefficacious, and were more likely to suffer from fear that significantly inhibited normal activities than were HC. In multinomial regression analyses, partial models indicated that sex, physical comorbidities, and the True Response Inconsistency (TRIN-r, Malaise (MLS, and Behavior-Restricting Fears (BRF dimensions of the MMPI-2-RF had significant effects on group differences. In conclusion, health care providers should assess the ongoing adjustment and emotional wellbeing of people with MPM and their

    Schizotypy has been proposed to be the expression of genetic vulnerability to schizophrenia. The available literature shows cognitive similarities between schizotypy and schizophrenia, with mildly impaired performance being associated with schizotypy. This study aims to determine the relationship between schizotypy and cognitive performance in siblings of patients with psychosis. Schizotypal features and cognitive performance on a neuropsychological battery were compared between 48 siblings of patients with psychosis and 44 healthy controls. The relationships between schizotypy and cognitive performance were analysed by controlling the condition of being a sibling. Siblings showed poorer performance on vigilance/sustained attention (M = 37.6; SD = 7.1) and selective attention/interference control/working memory (M = 23.28; SD = 2.7) tasks. The variance in vigilance/sustained attention performance was explained, at 30%, by the interpersonal factor of schizotypy on the suspiciousness dimension and the condition of being a sibling. Interpersonal features of schizotypy in siblings of patients with psychosis are associated with deficits in vigilance/sustained attention performance. Copyright © 2017 Elsevier B.V.

    Uncontrolled use of the internet has been reported to affect the lives of some users in a negative way. According to epidemiological studies, about 1% of the general population is showing signs of internet addiction. Since internet addiction is becoming a growing health concern, research on potential risk factors is becoming more important in order to develop strategies for prevention and to adopt therapeutic treatment. Although there are some studies investigating personality traits in internet addiction, most of these studies are based on samples of healthy subjects. In this research project, we compared personality profiles of a sample of patients in different rehabilitation centers. 70 patients with an addiction disorder that additionally met the criteria for internet addiction were compared to 48 patients suffering from alcohol dependence. Besides Big Five personality traits, we also assessed depressive symptoms. It was shown that patients with comorbid internet addiction can be discriminated from other patients by higher neuroticism and lower extraversion as well as lower conscientiousness. After controlling for depressive symptoms, lower conscientiousness especially turned out to be a disorder-specific risk factor. As internet addiction is related to unique patterns of personality traits and can be discriminated from alcohol dependence, treatment approaches are needed that meet the specific requirements of patients with internet addiction.

    Globin switching is a significant factor on blood hemoglobin (Hb) level but its molecular mechanisms have not yet been identified, however, several quantitative trait loci (QTL) and polymorphisms involved regions on chromosomes 2p, 6q, 8q and X account for variation in the γ-globin expression level. We studied the effect of interaction between a region on intron six of the TOX gene, chromosome 8q (chr8q) and XmnI locus on the γ-globin promoter, chr11p on γ-globin expression in 150 β-thalassemia intermedia (β-TI) patients, evaluated by statistical interaction analysis. Our results showed a significant interaction between one QTL on intron six of the TOX gene (rs9693712) and XmnI locus that effect γ-globin expression. Interchromosomal interaction mediates through transcriptional machanisms to preserve true genome architectural features, chromosomes localization and DNA bending. This interaction can be a part of the unknown molecular mechanism of globin switching and regulation of gene expression.

    This study investigated the association of personality traits with the baseline clinical characteristics and treatment outcomes of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Subjects were evaluated at baseline and at week 12 following routine treatment for CP/CPPS using the Korean version of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) to measure the severity of CP/CPPS; the Korean version of the Patient Health Questionnaire-9 (PHQ-9) to assess depression; the Korean version of the Patient Health Questionnaire-15 (PHQ-15) to evaluate somatization; and the Korean version of the EuroQol Questionnaire-5 Dimensions (EQ-5D), specifically the EQ-5D utility index and the EQ-5D visual analog scale (EQ-5D VAS), to assess quality of life (QoL). Personality traits including extraversion, agreeableness, conscientiousness, neuroticism, and openness were determined at baseline using the 44-item Big Five Inventory (BFI). The influence of personality traits on the clinical characteristics and treatment outcomes of patients with CP/CPPS was assessed using relevant statistical analyses. Neuroticism was associated with a significantly poorer treatment response and higher levels of depression and somatization. Extraversion, agreeableness, and conscientiousness had some influence on clinical characteristics but openness did not affect overall symptoms or the treatment response in patients with CP/CPPS. We found that neuroticism may be the most important personality trait associated with treatment response and the severity of depression and somatization in patients with CP/CPPS. However, our exploratory findings should be confirmed by additional studies with adequate power and improved designs. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Objectives: Multiple Sclerosis is an incurable and chronic disease of the central nervous system. The main purpose of this survey is to compare the character types and life expectancy of patients suffering from M. S as compared with normal people. This survey was conducted using the Persian translation of NEO-FFI (NEO-Five Factor Inventory and Herth Life Expectancy. Methods:Thirty nine people suffering from multiple sclerosis, who were hospitalized in anursing home, were chosen. As a control group there were 39 healthy people who had no background of physical or mental diseases. These people were selected from educational centre scientific and the personnel of Islamic Azad University, Science and Research Campus. Healthy people were matched to control group according, to sex, gender, marital status and education. Results: To analyze the data, T tests were used. The results of the survey show that people suffering from multiple sclerosis were significantly different from healthy people in three factors, neuroticism, extraversion and openness. For life expectancy there was no significant difference between the two groups. Discussion: Peopleaffected by Multiple Sclerosis achieve higher marks levels of the function of neuroticism compared with the healthy people. They are also agreeableness in a lower state, due to the function of openness to experience compared with the safe ones and in a lower state compared with the healthy persons.

    Full Text Available The aims of this work were to estimate the coefficient of relatedness within families and the genetic parameters for growth related traits in a progeny test from an open-pollinated variety of Pinus caribaea Morelet hondurensis Barret & Golfari, established in Mato Grosso do Sul State, Brazil. The experimental design was the triple 10 x 10 lattice, with 96 families, three replicates, and ten plants per plot. Fourteen years after planting, the trial was measured for the following traits: total height, diameter at breast height (DBH, and true volume. The estimation of coefficients of relatedness within family from microsatellite loci indicated that families are true half-sibs (^r xy = 0.253. Thus, the additive genetic variance (σ2A can be estimated assuming that the genetic variance among progenies (σ2p accounts for ¼ of additive genetic variance (^σ2A = 4^σ2p. The estimative of heritability coefficients at individual level (h i² was relatively high (0.28 for DBH and 0.44 for height. The heritability coefficient considering the average families (h m² was also high, ranging among the traits from 0.50 to 0.58. These results suggest that the population can be improved by both massal and among families selection. Additionally, the estimated genetic gains with sequential selection among and within families were high (ranging from 8.92% for height to 37.56% for volume, demonstrating that this method of selection can generate high genetic improvement.Os objetivos deste trabalho foram estimar o coeficiente de parentesco dentro de famílias e os parâmetros genéticos e fenotípicos para os caracteres de crescimento (altura, diâmetro a altura do peito e volume em um teste de progênies de polinização aberta de Pinus caribaea Morelet var. hondurensis Barret & Golfari, implantado no Estado de Mato Grosso do Sul, Brasil.

    Introduction Dans le but d'étudier l'aspect toxicologique des plantes médicinales utilisées en médecine traditionnelle, une étude ethnobotanique a été réalisée à la ville de Fès au centre du Maroc. Méthodes Ont été inclus dans l'étude tous les patients ayant bénéficié d'une prescription par l'herboriste de plantes à visée thérapeutique. La discussion de nos résultats s'est faite sur la base d'une revue de la littérature avec identification des principales plantes toxiques utilisées en phytothérapie au Maroc. L'approche bibliographique a permis de compléter les informations. Résultats L'âge moyen des patients traités par des plantes (38 femmes, 32 hommes) était de 35 ± 18 ans. L'enquête ethnobotanique à révélé que la majorité des plantes médicinales étaient utilisées contre les affections urinaires (21%), suivi des maladies de l'appareil digestif (19.6%) et des maladies rhumatologiques (18.2%). Le nombre de plantes prescrits par l'herboriste a été de 53 dont 5 sont potentiellement toxiques. L'identification taxonomique des plantes prescrites a recensé 30 familles dont les plus représentées sont les Lamiaceae (23.33%), les Apiaceae (13,33%) et les Asteraceae (10%). La prescription des plantes considérées comme toxiques a concerné 7,1% des consultants traités par les plantes médicinales. Aucune complication inhérente aux plantes prescrites n'a été déplorée. Conclusion Malgré les résultats encourageants de notre enquête sur le compte de la phytothérapie, la pratique de la phytothérapie est laissée à la vulgarisation et à l'oubli scientifique, législatif et universitaire.

    Influences of the Big Five personality traits on the treatment response and longitudinal course of depression in patients with acute coronary syndrome: A randomised controlled trial. This naturalistic observational study initially recruited 1152 ACS patients; 685 patients completed personality assessments at baseline, of whom 630 were followed-up one year later. Of the 294 patients with depression, 207 participated in a 24-week double blind trial of escitalopram or placebo. The remaining 87 patients who received medical treatment only and the 391 who had not depression were also followed in a one year naturalistic observational study. The Big five personality traits were assessed using the Big Five Inventory. The influences of personality on the Hamilton Depression Rating Scale score changes were analysed using a mixed-model repeated-measures analysis of covariance. A Cluster analysis identified two personality types: resilient and vulnerable. The vulnerable personality type was characterized by lower extraversion, agreeableness, and conscientiousness - but higher neuroticism - than the resilient type. This personality type was independently associated with a poorer outcome of depression in ACS patients during the 24-week treatment period and the one year longitudinal follow-up period compared to the resilient personality type, irrespective of treatment allocation. Recruitment from a single institution may limit generalisability. Personality traits were investigated 12-weeks after ACS; thus, the responses may have been influenced by the prior receipt of escitalopram. Personality types influences the treatment outcome and longitudinal course of depression in ACS patients independent of antidepressant treatment. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Recent studies investigating protease-activated receptor type 2 (PAR-2 suggest an association between the receptor and periodontal inflammation. It is known that gingipain, a bacterial protease secreted by the important periodontopathogen Porphyromonas gingivalis can activate PAR-2. Previous studies by our group found that PAR-2 is overexpressed in the gingival crevicular fluid (GCF of patients with moderate chronic periodontitis (MP. The present study aimed at evaluating whether PAR-2 expression is associated with chronic periodontitis severity. GCF samples and clinical parameters, including plaque and bleeding on probing indices, probing pocket depth and clinical attachment level, were collected from the control group (n = 19 at baseline, and from MP patients (n = 19 and severe chronic periodontitis (SP (n = 19 patients before and 6 weeks after periodontal non-surgical treatment. PAR-2 and gingipain messenger RNA (mRNA in the GCF of 4 periodontal sites per patient were evaluated by Reverse Transcription Polymerase Chain Reaction (RT-qPCR. PAR-2 and gingipain expressions were greater in periodontitis patients than in control group patients. In addition, the SP group presented increased PAR-2 and gingipain mRNA levels, compared with the MP group. Furthermore, periodontal treatment significantly reduced (p <0.05 PAR-2 expression in patients with periodontitis. In conclusion, PAR-2 is associated with chronic periodontitis severity and with gingipain levels in the periodontal pocket, thus suggesting that PAR-2 expression in the GCF reflects the severity of destruction during periodontal infection.

The safety, pharmacokinetic, biodistribution profile and radiation dosimetry after a single intravenous dose of (64)Cu-DOTA-AE105 were assessed by serial PET and computed tomography (CT) in 4 prostate, 3 breast and 3 bladder cancer patients. Safety assessment...... of invasion, metastasis and indicates poor prognosis. uPAR PET imaging therefore holds promise to be a new and innovative method for improved cancer diagnosis, staging and individual risk stratification. The uPAR specific peptide AE105 was conjugated to the macrocyclic chelator DOTA and labeled with (64)Cu...

    Full Text Available CONTEXTO: Os sintomas de transtornos de personalidade (Eixo II comumente encontrados em pacientes com fobia social se sobrepõem com os sintomas que descrevem o transtorno pelo Eixo I. OBJETIVO: O presente estudo teve por objetivo avaliar traços de personalidade em pacientes com diagnóstico de fobia social. MÉTODO: Cento e oito sujeitos com idade entre 18 e 65 anos foram avaliados pelo Inventário de Temperamento e Caráter de Cloninger. RESULTADO: Os pacientes com fobia social diferiram dos dados normativos nos seguintes traços de personalidade: Busca à Novidade, Fuga de Danos, Persistência, Autodirecionamento e Autotranscendência. CONCLUSÃO: Esses achados apontam para uma sobreposição entre a descrição dos traços de personalidade citados por Cloninger e a descrição dos sintomas de fobia social do DSM-IV, Eixo I.BACKGROUND: The symptoms of personality disorders (Axis II commonly found in social phobia patients overlap highly with the symptoms that typify the Axis I disorder and are thus linked to diagnostic process in symptomatic patients. OBJECTIVE: The aim of the present study was to evaluate personality traits of social phobia patients. METHOD: One hundred and eight subjects were selected, from 18 to 65 years of age, who fulfilled the criteria of social phobia. The Cloninger's Temperament and Character Inventory (TCI was applied. RESULTS: Social phobia patients differed in normalized data in the following personality traits: Novelty Seeking, Harm Avoidance, Persistence, Self Directedness, and Self-Transcendence. DISCUSSION: These findings point to a high overlap between Cloninger's description of the observed predominant personality traits and DSM-IV Axis I symptoms description for social phobia.

    Recent life events are associated with transition to and outcome in psychosis. Childhood trauma and personality characteristics play a role in proneness to adult life events. However, little is known about the relative contribution and interrelatedness of these characteristics in psychotic disorders. Therefore, we investigated whether Five-Factor Model (FFM) personality traits and childhood trauma (abuse and neglect) predict adult life events, and whether the effect of childhood trauma on life events is mediated by personality traits. One hundred and sixty-three patients with psychotic disorders were assessed at baseline on history of childhood maltreatment and FFM personality traits, and on recent life events at 3-year follow-up. Childhood abuse is associated with negative life events, and part of the effect of childhood abuse on negative life events is mediated by openness to experience. Openness to experience and extraversion are associated with more positive and negative life events. Childhood neglect and lower extraversion are related to experiencing less positive events. The association between childhood trauma and recent life events is partly mediated by personality. Future research could focus on mechanisms leading to positive life events, as positive life events may buffer against development of mental health problems.

    The water level of Par Pond was lowered approximately 20 feet in mid-1991 in order to protect downstream residents from possible dam failure suggested by subsidence on the downstream slope of the dam and to repair the dam. This lowering exposed both emergent and nonemergent macrophyte beds to drying conditions resulting in extensive losses. A survey of the newly emergent, shoreline aquatic plant communities of Par Pond began in June 1995, three months after the refilling of Par Pond to approximately 200 feet above mean sea level. These surveys continued in July, September, and late October, 1995, and into the early spring and late summer of 1996. Communities similar to the pre-drawdown, Par Pond aquatic plant communities continue to become re-established. Emergent beds of maidencane, lotus, waterlily, watershield, and Pontederia are extensive and well developed. Measures of percent cover, width of beds, and estimates of area of coverage with satellite data indicate regrowth within two years of from 40 to 60% of levels prior to the draw down. Cattail occurrence continued to increase during the summer of 1996, especially in the former warm arm of Par Pond, but large beds common to Par Pond prior to the draw down still have not formed. Lotus has invaded and occupies many of the areas formerly dominated by cattail beds. To track the continued development of macrophytes in Par Pond, future surveys through the summer and early fall of 1997, along with the evaluation of satellite data to map the extent of the macrophyte beds of Par Pond, are planned

    This study sought to discover if an optimum 1 cm2 area in the non-damaged right hemisphere (RH) was present, which could temporarily improve naming in chronic, nonfluent aphasia patients when suppressed with repetitive transcranial magnetic stimulation (rTMS). Ten minutes of slow, 1 Hz rTMS was applied to suppress different RH ROIs in eight aphasia cases. Picture naming and response time (RT) were examined before, and immediately after rTMS. In aphasia patients, suppression of right pars triangularis (PTr) led to significant increase in pictures named, and significant decrease in RT. Suppression of right pars opercularis (POp), however, led to significant increase in RT, but no change in number of pictures named. Eight normals named all pictures correctly; similar to aphasia patients, RT significantly decreased following rTMS to suppress right PTr, versus right POp. Differential effects following suppression of right PTr versus right POp suggest different functional roles for these regions. PMID:21864891

    Full Text Available Background: The left superior temporal gyrus (STG has been suggested to play a key role in auditory verbal hallucinations in patients with schizophrenia. Methods: Eleven medicated subjects with schizophrenia and medication-resistant auditory verbal hallucinations and 19 healthy controls underwent perfusion magnetic resonance imaging with arterial spin labeling. Three additional repeated measurements were conducted in the patients. Patients underwent a treatment with transcranial magnetic stimulation (TMS between the first 2 measurements. The main outcome measure was the pooled cerebral blood flow (CBF, which consisted of the regional CBF measurement in the left superior temporal gyrus (STG and the global CBF measurement in the whole brain.Results: Regional CBF in the left STG in patients was significantly higher compared to controls (p < 0.0001 and to the global CBF in patients (p < 0.004 at baseline. Regional CBF in the left STG remained significantly increased compared to the global CBF in patients across time (p < 0.0007, and it remained increased in patients after TMS compared to the baseline CBF in controls (p < 0.0001. After TMS, PANSS (p = 0.003 and PSYRATS (p = 0.01 scores decreased significantly in patients.Conclusions: This study demonstrated tonically increased regional CBF in the left STG in patients with schizophrenia and auditory hallucinations despite a decrease in symptoms after TMS. These findings were consistent with what has previously been termed a trait marker of auditory verbal hallucinations in schizophrenia.

    Summary Les enfants célèbrent la fête de Achoura au Maroc par des jeux de feu, ce qui occasionne des blessures oculaires plus au moins graves. Nous rapportons 15 observations de malades traités au Service d'Ophtalmologie Pédiatrique de l'Hôpital 20 Août 1953 de Casablanca. L'âge moyen des patients était de 12 ans et demi, avec des extrêmes de 3 et 25 ans. Les pétards, la première cause des accidents (50%), ont occasionné des contusions oculaires avec parfois un oedème de Berlin (deux cas). L'atteinte oculaire par fusée a occasionné un éclatement de globe et une plaie de paupière. Les bombes de carbone ont été responsables de brûlures de deuxième degré palpébrales et conjonctivo-cornéennes avec de multiples corps étrangers cornéens profonds. Les «étoiles» et la limaille de fer ont provoqué des brûlures cornéennes moins graves avec des corps étrangers superficiels. Les pistolets à bille ont été responsables de contusions oculaires. La réglementation de vente des jeux de feu et la sensibilisation du grand public par les moyens audiovisuels permettraient de prévenir ces blessures oculaires. PMID:21991053

    Résumé Objectif Étudier entre 1996 et 2006, l’évolution des schémas thérapeutiques et du profil clinique et immunologique des patients infectés par le VIH au début du traitement antirétroviral (TARV) en Afrique de l’Ouest. Cadre et méthode Les données issues de 12 centres cliniques adultes (IeDEA West Africa réseau collaboratif de prise en charge de l’infection à VIH) de cinq pays (Bénin, Cote d’Ivoire, Sénégal, Gambie, Mali) ont été mises en commun et analysées. Les patients âgés de 16 ans et plus dont le sexe, la date de naissance et la date d’initiation du TARV étaient connus ont été inclus dans cette étude. Résultats Quatorze mille quatre-cent-quatre-vingt-seize patients avaient débuté un TARV entre 1996–2006 avec 55 % des patients l’ayant débuté entre 2005–2006. La proportion de femmes était de 46 % en 1996–2000 et de 63 % en 2005–2006. L’âge médian à la mise sous traitement était constant: 35 ans chez les femmes et 40 ans chez les hommes. La proportion de patients qui ont débuté le TARV avec un taux de CD4 inférieur à 200 cellules/µl était de 54 % en 1996–2000 et de 64 % en 2005–2006. Les combinaisons thérapeutiques les plus prescrites étaient: AZT/3TC (ou d4T/DDI)/IDV (27 %) en 1996–2000; d4T (ou AZT)/3TC/EFV (59 %) en 2003–2004; et d4T/3TC/NVP (49 %) en 2005–2006. Les traitements de première ligne recommandés par l’OMS étaient débutés dans 83 % de cas en 2005–2006. Conclusion De nouvelles approches pour débuter un TARV plus précocement doivent être développées pour améliorer la survie des patients sous TARV. PMID:20045273

    Near infrared intra-operative optical imaging is an emerging technique with clear implications for improved cancer surgery by enabling a more distinct delineation of the tumor margins during resection. This modality has the potential to increase the number of patients having a curative radical...... tumor resection. In the present study, a new uPAR-targeted fluorescent probe was developed and the in vivo applicability was evaluated in a human xenograft mouse model. Most human carcinomas express high level of uPAR in the tumor-stromal interface of invasive lesions and uPAR is therefore considered...... an ideal target for intra-operative imaging. Conjugation of the flourophor indocyanine green (ICG) to the uPAR agonist (AE105) provides an optical imaging ligand with sufficiently high receptor affinity to allow for a specific receptor targeting in vivo. For in vivo testing, human glioblastoma xenograft...

    Introduction The serotonergic neurotransmitter system is closely linked to depression and personality traits. It is not known if selective serotonin reuptake inhibitors (SSRI) have an effect on neuroticism that is independent of their effect on depression. Healthy individuals with a genetic liability for depression represent a group of particular interest when investigating if intervention with SSRIs affects personality. The present trial is the first to test the hypothesis that escitalopram may reduce neuroticism in healthy first-degree relatives of patients with major depressive disorder (MD). Methods The trial used a randomized, blinded, placebo-controlled parallel-group design. We examined the effect of four weeks escitalopram 10 mg daily versus matching placebo on personality in 80 people who had a biological parent or sibling with a history of MD. The outcome measure on personality traits was change in self-reported neuroticism scores on the Revised Neuroticism-Extroversion-Openness-Personality Inventory (NEO-PI-R) and the Eysenck Personality Inventory (EPQ) from entry until end of four weeks of intervention. Results When compared with placebo, escitalopram did not significantly affect self-reported NEO-PI-R and EPQ neuroticism and extroversion, EPQ psychoticism, NEO-PI-R openness, or NEO-PI-R conscientiousness (p all above 0.05). However, escitalopram increased NEO-PI-R agreeableness scores significantly compared with placebo (mean; SD) (2.38; 8.09) versus (−1.32; 7.94), p = 0.046), but not following correction for multiplicity. A trend was shown for increased conscientiousness (p = 0.07). There was no significant effect on subclinical depressive symptoms (p = 0.6). Conclusion In healthy first-degree relatives of patients with MD, there is no effect of escitalopram on neuroticism, but it is possible that escitalopram may increase the personality traits of agreeableness and conscientiousness.

    Ureaplasma spp. cause several disorders, such as nongonococcal urethritis, miscarriage, and preterm delivery with lung infections in neonates, characterized by pathological chorioamnionitis in the placenta. Although reports on antibiotic resistance in Ureaplasma are on the rise, reports on quinolone-resistant Ureaplasma infections in Japan are limited. The purpose of this study was to determine susceptibilities to five quinolones of Ureaplasma urealyticum and Ureaplasma parvum isolated from perinatal samples in Japan and to characterize the quinolone resistance-determining regions in the gyrA, gyrB, parC, and parE genes. Out of 28 clinical Ureaplasma strains, we isolated 9 with high MICs of quinolones and found a single parC gene mutation, resulting in the change S83L. Among 158 samples, the ParC S83L mutation was found in 37 samples (23.4%), including 1 sample harboring a ParC S83L-GyrB P462S double mutant. Novel mutations of ureaplasmal ParC (S83W and S84P) were independently found in one of the samples. Homology modeling of the ParC S83W mutant suggested steric hindrance of the quinolone-binding pocket (QBP), and de novo prediction of peptide structures revealed that the ParC S84P may break/kink the formation of the α4 helix in the QBP. Further investigations are required to unravel the extent and mechanism of antibiotic resistance of Ureaplasma spp. in Japan. Copyright © 2015, American Society for Microbiology.

    To compare outcomes of phacoaspiration (PA) with Cionni ring-assisted posterior-chamber intraocular lens implantation (PCIOL) versus pars plana lensectomy (PPL) with anterior vitrectomy (AV) and sutureless transscleral fixation of the IOL (TSFIOL) assisted with fibrin glue in the management of a subluxated lens. In this prospective and comparative interventional study, one eye of children with a bilateral subluxated lens was randomized to undergo PA with PCIOL using a Cionni ring (group A: n = 14 eyes), and the other eye underwent PPL + AV with glue-assisted TSFIOL (group B: n = 14 eyes). The outcome measures included best-corrected visual acuity (BCVA) in logMAR units and rates of complications at 12-month follow-up visits. 28 eyes of 14 children (age: 8.06 ± 4.49 years) were included in the study. BCVA improved from preoperative value of 1.21 to 0.4 (p = 0.001) in group A and from 1.53 to 0.31 (p = 0.001) in group B at month 12. There was no significant difference in the BCVA on comparing the two groups at month 12 (p > 0.411). Postoperative complications in group A included corneal edema (two eyes), Cionni hook capture (one eye), elevated IOP (one eye), and posterior capsular opacification (five eyes). In group B, corneal edema was seen in two eyes, hypotony in one eye, vitreous hemorrhage in one eye and pupillary optic capture in four eyes. Head-to-head comparison of the two techniques demonstrates no significant difference in the rates of complications at month 12. The decision to choose either technique may be based on the operating surgeon's skill, experience and preference.

    Recent studies investigating protease-activated receptor type 2 (PAR-2) suggest an association between the receptor and periodontal inflammation. It is known that gingipain, a bacterial protease secreted by the important periodontopathogen Porphyromonas gingivalis can activate PAR-2. Previous studies by our group found that PAR-2 is overexpressed in the gingival crevicular fluid (GCF) of patients with moderate chronic periodontitis (MP). The present study aimed at evaluating whether PAR-2 expression is associated with chronic periodontitis severity. GCF samples and clinical parameters, including plaque and bleeding on probing indices, probing pocket depth and clinical attachment level, were collected from the control group (n = 19) at baseline, and from MP patients (n = 19) and severe chronic periodontitis (SP) (n = 19) patients before and 6 weeks after periodontal non-surgical treatment. PAR-2 and gingipain messenger RNA (mRNA) in the GCF of 4 periodontal sites per patient were evaluated by Reverse Transcription Polymerase Chain Reaction (RT-qPCR). PAR-2 and gingipain expressions were greater in periodontitis patients than in control group patients. In addition, the SP group presented increased PAR-2 and gingipain mRNA levels, compared with the MP group. Furthermore, periodontal treatment significantly reduced (p periodontitis. In conclusion, PAR-2 is associated with chronic periodontitis severity and with gingipain levels in the periodontal pocket, thus suggesting that PAR-2 expression in the GCF reflects the severity of destruction during periodontal infection.

    To study the safety and efficacy of 2-port pars plana anterior and central core vitrectomy (Lam floaterectomy) in combination with phacoemulsification (phaco) and intraocular lens implantation (IOL) for patients with cataract and significant floaters under topical anesthesia. Retrospective review of the first 50 consecutive cases. A standardized treatment protocol was used for patients with cataract and significant (moderate to severe) floaters (duration > 3 months). Data analysis included intraoperative and postoperative complications, floater status, and patient satisfaction. There were 50 eyes (38 patients) with a male-to-female ratio of 1 to 2.3. Twelve patients had bilateral eye surgeries. Mean age was 58.10 ± 9.85 years (range, 39-83). All patients completed the 3-month follow-up. One eye had mild vitreous hemorrhage at the end of surgery arising from sclerotomy wound oozing. No other intraoperative compli-cations were encountered. Postoperatively, there was 1 case of transient hypotony and 1 case of congestion at sclerotomy wound. No cases of retinal break or detachment, or clinically significant macular edema, were reported. There were 5 cases (10%) of mild residual floaters and 1 case (2%) of floater recurrence. Total floater clearance rate was 88%. Patient satisfaction rates were 80%, 14%, 6%, and 0% for very satisfied, satis-fied, acceptable, and unsatisfied, respectively. The 3-month results in terms of safety and efficacy of the Lam floaterectomy in combination with phaco and IOLfor patients with cataract and significant floaters under topical anesthesia are encouraging. Further larger-scale, prospective, multicenter studies seem warranted. Copyright© 2017 Asia-Pacific Academy of Ophthalmology.

    Personality is considered as an important aspect in persons with psychotic disorders. Several studies have investigated personality in schizophrenia. However, no study has investigated stability of personality traits exceeding three years in patients with schizophrenia. This study aims to investigate the stability of personality traits over a five-year period among patients with schizophrenia and non-psychotic individuals and to evaluate case-control differences. Patients with psychotic disorders (n = 36) and non-psychotic individuals (n = 76) completed Swedish universities Scales of Personality (SSP) at two occasions five years apart. SSP scores were analysed for effect of time and case-control differences by multiple analysis of covariance (MANCOVA) and within-subjects correlation. MANCOVA within-subjects analysis did not show any effect of time. Thus, SSP mean scale scores did not significantly vary during the five-year interval. Within subject correlations (Spearman) ranged 0.30-0.68 and 0.54-0.75 for the different SSP scales in patients and controls, respectively. Patients scored higher than controls in SSP scales Somatic Trait Anxiety, Psychic Trait Anxiety, Stress Susceptibility, Lack of Assertiveness, Detachment, Embitterment, and Mistrust. The stability of the SSP personality trait was reasonably high among patients with psychotic disorder, although lower than among non-psychotic individuals, which is in accordance with previous research.

    Borderline personality disorder (BPD) and eating disorders may affect the outcomes of bariatric surgery. This study was aimed to evaluate the influence of a post-operative dialectical behavioral therapy (DBT) intervention on weight loss and comorbidities in a sample of comorbid obese Italian patients with BPD traits and bulimia tendencies who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic adjustable gastric banding (LAGB). One hundred fifty-four LRYGB or LAGB patients showing BPD and bulimia traits and type II diabetes, hypertension, and/or sleep apnea (OSAS) voluntarily adhered to DBT (n = 72) or treatment as usual (n = 82) for 12 months after surgery. Total weight loss (%TWL) and remission/improvement of comorbidities were considered as outcomes. Differences between treatment groups and between LRYGB and LAGB subgroups were evaluated through Student's t test for TWL and chi-square test for comorbidities. DBT was more effective than treatment as usual (TAU) in reducing weight loss (p bulimia tendencies. Further in-depth investigations and a longer follow-up are needed to strengthen these results.

    Our aim in the current study was to evaluate the convergence between Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) Section III dimensional personality traits, as operationalized via the Personality Inventory for DSM-5 (PID-5), and Minnesota Multiphasic Personality Inventory 2-Restructured Form (MMPI-2-RF) scale scores in a psychiatric patient sample. We used a sample of 346 (171 men, 175 women) patients who were recruited through a university-affiliated psychiatric facility in Toronto, Canada. We estimated zero-order correlations between the PID-5 and MMPI-2-RF substantive scale scores, as well as a series of exploratory structural equation modeling (ESEM) analyses to examine how these scales converged in multivariate latent space. Results generally showed empirical convergence between the scales of these two measures that were thematically meaningful and in accordance with conceptual expectations. Correlation analyses showed significant associations between conceptually expected scales, and the highest associations tended to be between scales that were theoretically related. ESEM analyses generated evidence for distinct internalizing, externalizing, and psychoticism factors across all analyses. These findings indicate convergence between these two measures and help further elucidate the associations between dysfunctional personality traits and general psychopathology.

Univariate regression analysis showed that better baseline visual acuity (OR=0.38, 95%CI 0.21-0.70, P=0.002, age older than 5 years at disease onset (OR=0.36, 95%CI 0.14-0.9, P=0.029, absence of endotheliitis (OR=0.39, 95%CI 0.15-0.99, P=0.047 and female gender (OR=3.77, 95%CI 1.03-13.93, P=0.046 were significantly associated with final BCVA of 20/40 or better. Conclusion: Childhood pars planitis was much more common among male subjects. Endotheliitis may be a sign of inflammation spillover and is more prevalent in younger patients. Visual prognosis is favorable in most patients with appropriate treatment.

    Full Text Available External signals that are mediated by specific receptors determine stem cell fate. The thrombin receptor PAR1 plays an important role in haemostasis, thrombosis and vascular biology, but also in tumor biology and angiogenesis. Its expression and function in hematopoietic stem cells is largely unknown. Here, we analyzed expression and function of PAR1 in primary hematopoietic cells and their leukemic counterparts. AML patients' blast cells expressed much lower levels of PAR1 mRNA and protein than CD34+ progenitor cells. Constitutive Par1-deficiency in adult mice did not affect engraftment or stem cell potential of hematopoietic cells. To model an AML with Par1-deficiency, we retrovirally introduced the oncogene MLL-AF9 in wild type and Par1-/- hematopoietic progenitor cells. Par1-deficiency did not alter initial leukemia development. However, the loss of Par1 enhanced leukemic stem cell function in vitro and in vivo. Re-expression of PAR1 in Par1-/- leukemic stem cells delayed leukemogenesis in vivo. These data indicate that Par1 contributes to leukemic stem cell maintenance.

    Full Text Available This study is a continuation of the work of Professor Kazimierz Wrześniewski. It concerns the role of curiositytrait in the dynamics of changes in coping and quality of life after a heart attack. The study was attended by 222 people after a heart attack (73% men, of whom 140 participated in the three stages of the study: at the beginning and at the end of cardiac rehabilitation and a year after leaving the resort. The participants aged 24-64 years (M = 54.19; SD = 6.51. Curiosity-trait was measured by Spielberger and Wrześniewski’s STPI questionnaire. To assess coping strategies a modified version of the COPE by Carver et al., was used. The specific and general quality of life were measured by the Polish adaptations of MacNew and NHP questionnaires. The level of curiosity-trait significantly differentiated changes in the dynamics of positive reinterpretation, problem solving and resignation, but did not affect the change in quality of life within the year after a heart attack.

    Sickle cell disease (SCD) is the most common inherited disorder of haemoglobin worldwide. This study evaluated the chromatographic patterns and red blood cell indices of sickle cell patients to determine the co-inheritance of other haemoglobin(Hb) variants and β-thalassaemia trait. Red cell indices, blood film, sickle solubility test, Hb electrophoresis using alkaline cellulose acetate membrane, and chromatographic patterns using Bio Rad HPLC Variant II were evaluated for 180 subjects. Based on low MCV 4.0% on HPLC and Hb variants eluting outside the S and C windows, at least four haemoglobin phenotypes (SS: 87.7%; SC: 1.1%; SD Punjab: 0.6%; Sβ-thalassemia: 10.6%) were identified. Mean Hb F% was 8.1±5.1 (median 7.65) for Hb SS and 6.03±5.2 (median 3.9) for Hb Sβ-thalassemia trait. Majority of Hb SS (69.1%) had Hb F% less than 10 while 27.6% had 10-19.9 and 3.2% had ≥ 20. Mean Hb F% was higher in female Hb SS (9.55±5.09; mean age 7.4±3.8 years) than the males (7.63±4.80; mean age 6.9±3.8 years) (P=0.02). A borderline significant negative correlation between age and Hb F levels among Hb SS subjects (r= -0.169 P=0.038) was also observed. Our data suggests that α and β- thalassaemia traits, and other haemoglobin variants co-exist frequently with SCD in our population.

    2011-10-01

    Full Text Available INTRODUCTION: Human cytomegalovirus is an opportunistic betaherpesvirus that causes persistent and serious infections in immunodeficient patients. Recurrent infections occur due to the presence of the virus in a latent state in some cell types. It is possible to examine the virus using molecular methods to aid in the immunological diagnosis and to generate a molecular viral profile in immunodeficient patients. The objective of this study was to characterize cytomegalovirus genotypes and to generate the epidemiological and molecular viral profile in immunodeficient patients. METHODS: A total of 105 samples were collected from immunodeficient patients from the City of Belém, including newborns, hemodialysis patients, transplant recipients and HIV+ patients. An IgG and IgM antibody study was completed using ELISA, and enzymatic analysis by restriction fragment length polymorphism (RFLP was performed to characterize viral genotypes. RESULTS: It was observed that 100% of the patients had IgG antibodies, 87% of which were IgG+/IgM-, consistent with a prior infection profile, 13% were IgG+/IgM+, suggestive of recent infection. The newborn group had the highest frequency (27% of the IgG+/IgM+ profile. By RFLP analysis, only one genotype was observed, gB2, which corresponded to the standard AD169 strain. CONCLUSIONS: The presence of IgM antibodies in new borns indicates that HCMV continues to be an important cause of congenital infection. The low observed genotypic diversity could be attributed to the small sample size because newborns were excluded from the RFLP analysis. This study will be continued including samples from newborns to extend the knowledge of the general and molecular epidemiology of HCMV in immunodeficient patients.

    Obsessive-compulsive personality disorder (OCPD) traits and obsessive-compulsive disorder (OCD) are commonly associated with patients with Anorexia Nervosa (AN). The aim of this review was to systematically search the literature to examine whether OCPD and OCD are positively associated with excessive exercise in patients with AN. A systematic electronic search of the literature (using PsycInfo, Medline and Web of Knowledge) was undertaken to identify relevant publications until May 2012. A total of ten studies met criteria for inclusion in the review. The design of the studies varied from cross-sectional to retrospective and quasi-experimental. Seven out of the ten studies reviewed demonstrated a positive relationship between OCPD and/or OCD in AN patients who exercise excessively, whilst three studies found a lack of relationship, or a negative relationship, between these constructs. There is evidence from the literature to suggest that there is a positive relationship between OCPD and excessive exercise in patients with AN. However, the relationship between OCD and excessive exercise is less clear and further research is required to qualify the strength of such relationships. Future research should utilise the most comprehensive and reliable clinical assessment tools, and address prognostic factors, treatment factors and specific interventions for patients with OCPD and/or OCD and excessive exercise.

    To assess the alterations in keratometric astigmatism following the 25-gauge transconjunctival sutureless pars plana vitrectomy versus the conventional pars plana vitrectomy. Sixteen consecutive patients were enrolled into the study. Conventional vitrectomy was applied to eight of the cases and 25-gauge transconjunctival sutureless vitrectomy was performed in eight patients. Keratometry was performed before and after the surgery. In the 25-gauge transconjunctival sutureless pars plana vitrectomy group, statistically significant changes were not observed in the corneal curvature in any post-operative follow-up measurement (p > 0.05); whereas in the conventional pars plana vitrectomy group, statistically significant changes were observed in the first postoperative day (p = 0.01) and first postoperative month (p = 0.03). We noted that these changes returned to baseline in three months (p = 0.26). Both 25-gauge transconjunctival sutureless and conventional pars plana vitrectomy are effective surgical modalities for selected diseases of the posterior segment. Surgical procedures are critical for the visual rehabilitation of the patients. The post-operative corneal astigmatism of the vitrectomised eyes can be accurately determined at least two months post-operatively.

    Poorer health outcomes and disproportionate healthcare use in socioeconomically disadvantaged patients is well established. However, there is sparse literature on effective integrated care interventions that specifically target these high-risk individuals. The Integrated Community of Care (ICoC) is a novel care model that integrates hospital-based transitional care with health and social care in the community for high-risk individuals living in socially deprived communities. This study aims to evaluate the effectiveness of the ICoC in reducing acute hospital use and investigate the implementation process and its effects on clinical outcomes using a mixed-methods participatory action research (PAR) approach. This is a single-centre prospective, controlled, observational study performed in the SingHealth Regional Health System. A total of 250 eligible patients from an urbanised low-income community in Singapore will be enrolled during their index hospitalisation. Our PAR model combines two research components: quantitative and qualitative, at different phases of the intervention. Outcomes of acute hospital use and health-related quality of life are compared with controls, at 30 days and 1 year. The qualitative study aims at developing a more context-specific social ecological model of health behaviour. This model will identify how influences within one's social environment: individual, interpersonal, organisational, community and policy factors affect people's experiences and behaviours during care transitions from hospital to home. Knowledge on the operational aspects of ICoC will enrich our evidence-based strategies to understand the impact of the ICoC. The blending of qualitative and quantitative mixed methods recognises the dynamic implementation processes as well as the complex and evolving needs of community stakeholders in shaping outcomes. Ethics approval was granted by the SingHealth Centralised Institutional Review Board (CIRB 2015/2277). The findings

    Purpose. To assess functional and morphological alterations following video-documented surgery for epiretinal membranes. Methods. Forty-two patients underwent video-documented 23-gauge vitrectomy with peeling of epiretinal (ERM) and inner limiting membrane (ILM). Patient assessment was performed before and 3 and 6 months including best corrected visual acuity (BCVA), slit lamp biomicroscopy, SD-OCT, and central 2° and 18° microperimetry. In addition, all video-documented areas of peeling on the retinal surface were evaluated postoperatively using an additional focal 2° microperimetry. Retinal sensitivity and BCVA were correlated with morphological changes (EZ and ELM) in the foveal region and in regions of membrane peeling. Results. Overall, BCVA increased from 0.6 (±0.2) to 0.2 (±0.2) logMAR after 6 months with an increase in retinal sensitivity (17.9 ± 2.7 dB to 26.8 ± 3.1 dB, p peeling areas (p peeling and overall retinal sensitivity regarding visual acuity gain could be observed after 6 months (p > 0.05). In contrast, overall postoperative retinal sensitivity was significantly decreased in patients with a visual acuity gain lower than 2 lines (p peeling due to the use of intraocular forceps may affect the outer retinal structure. Nevertheless, these changes seem to have no significant impact on postoperative functional outcome.

    Horizontal transfer of malignant traits from the primary tumor to distant organs, through blood circulating factors, has recently become a thoroughly studied metastatic pathway to explain cancer dissemination. Recently, we reported that oncosuppressor gene-mutated human cells undergo malignant transformation when exposed to cancer patients' sera. We also observed that oncosuppressor mutated cells would show an increased uptake of cancer-derived exosomes and we suggested that oncosuppressor genes might protect the integrity of the cell genome by blocking integration of cancer-derived exosomes. In the present study, we tested the hypothesis that cancer patients' sera-derived exosomes might be responsible for the malignant transformation of target cells and that oncosuppressor mutation would promote their increased uptake. We also sought to unveil the mechanisms behind the hypothesized phenomena. We used human BRCA1 knockout (BRCA1-KO) fibroblasts as target cells. Cells were treated in vitro with cancer patients' sera or cancer patients' sera-derived exosomes. Treated cells were injected into NOD-SCID mice. Immunohistochemical analyses were performed to determine the differentiation state of the xenotransplants. Mass spectrometry analyses of proteins from cancer exosomes and the BRCA1-KO fibroblasts' membrane were performed to investigate possible de novo expression of molecules involved in vesicles uptake. Blocking of the identified molecules in vitro was performed and in vivo experiments were conducted to confirm the role of these molecules in the malignant transformation carried out by cancer-derived exosomes. Cells treated with exosomes isolated from cancer patients' sera underwent malignant transformation and formed tumors when transplanted into immunodeficient mice. Histological analyses showed that the tumors were carcinomas that differentiated into the same lineage of the primary tumors of blood donors. Oncosuppressor mutation promoted the de novo expression

    Chronic whiplash-associated disorders (chronic WAD) cover a large variety of clinical manifestations that can occur after a whiplash injury. Women have an increased risk of developing chronic WAD, and it is suggested that psychosocial factors are related to long-term pain and functioning following whiplash injury and persistence of chronic pain. This leads to the question whether there are sex differences in psychosocial factors in chronic WAD. This study included 117 subjects who had experienced a whiplash injury at least 3 months before the start of the study (mean duration of pain: 67.29 ± 63.86 months, range: 297 months). They were selected as chronically symptomatic, by excluding those who had recovered from their whiplash injury. Psychosocial aspects (including depression, fear, somatization, social support, and personality traits) were assessed by validated questionnaires, and sex differences were tested using a univariate analysis of variance (ANCOVA), with age and time from whiplash injury as covariates. No differences in depression, fear, somatization, discrepancy in social support personality trait, Neck Disability Index scores, physical functioning, bodily pain, or general health were present between women and men with chronic WAD. Women with chronic WAD reported higher levels of emotional support in problem situations and social companionship. Except for emotional support in problem situations and social companionship, psychosocial factors do not differ between men and women with chronic WAD. These findings imply little to no risk for sex bias in studies investigating psychosocial issues in patients with chronic WAD. © 2014 World Institute of Pain.

    Engaging in online games has become increasingly important as a part of leisure activity in adolescents and adults. While the majority of people use these games in a healthy way, epidemiological studies show that some develop excessive use and symptoms that are related to those of substance-related addictions. Despite increasing research concerning the epidemiology of internet gaming disorder (IGD), predisposing factors have been examined to a lesser extent. Knowing about specific risk factors would help clarify the nosological features of IGD and enhance prevention and intervention. This study aimed to evaluate the relationships between personality traits and IGD. A total of 115 patients meeting the criteria for IGD were compared to 167 control subjects displaying either regular or intense use of online games. Additionally, 115 patients meeting diagnostic criteria for pathological gambling were included. IGD was associated with higher neuroticism, decreased conscientiousness and low extraversion. The comparisons to pathological gamblers indicate that low conscientiousness and low extraversion in particular are characteristic of IGD. An integration of personality variables into an etiopathological model describing presumable mechanisms fostering and maintaining addictive online gaming is proposed. This model could be helpful for the theoretical understanding of addictive gaming, public health campaigns and psychoeducation within therapeutic settings. © 2013 S. Karger AG, Basel.

Abnormal glutamatergic transmission in the striatum is considered a key factor in the development of LIDs. This work aims at i. characterizing NMDA receptor GluN2A/GluN2B subunit ratio as a common synaptic trait in rat and primate models of LIDs and in dyskinetic PD patients, and ii. validating the potential therapeutic effect of a cell-permeable peptide interfering with GluN2A synaptic localization on the dyskinetic behavior of these experimental models of LIDs. Here we demonstrate an altered ratio of synaptic GluN2A/GluN2B-containing NMDA receptors in the striatum of levodopa-treated dyskinetic rats and monkeys as well as in post-mortem tissue from dyskinetic PD patients. The modulation of synaptic NMDA receptor composition by a cell-permeable peptide interfering with GluN2A subunit interaction with the scaffolding protein PSD-95 leads to a reduction in the dyskinetic motor behavior in the two animal models of LIDs. Our results indicate that targeting synaptic NMDA receptor subunit composition may represent an intriguing therapeutic approach aimed at ameliorating levodopa motor side effects.

    Brugada syndrome (BrS) is a primary electrical heart disease, which can lead to sudden cardiac death. In older patients with BrS, the disease may coexist with ischaemic heart disease (IHD) and recent studies support a synergistic proarrhythmic effect of the two disease entities. We report a case...

    Recent work suggests that predictors of violence are similar for individuals with and without mental illness. Although psychopathy is among the most potent of such predictors, the nature of its relation to violence is unclear. On the basis of a sample of 769 civil psychiatric patients, the authors explore the possibility that measures of…

    Clinical and psychosocial attributes are associated with clinical outcomes after total knee replacement (TKR) surgery in patients with osteoarthritis (OA), but their relationship with TKR-related costs is less clear. Our objective was to evaluate the effect of clinical and psychosocial attributes on TKR costs. We conducted a 6-month prospective cohort study of patients with knee OA who underwent TKR. We examined baseline demographic, clinical [body mass index (BMI) and comorbidities], and psychosocial attributes (social support, locus of control, coping, depression, anxiety, stress, and self-efficacy); baseline and 6-month OA clinical outcomes [Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function]; and 6-month direct and indirect TKR-related costs. Multiple regression was performed to identify determinants of TKR-related costs. We included 212 patients; 66% were women, 71% were white, and the mean age was 65.2 years. The mean baseline WOMAC pain score was 55 (SD 19) and WOMAC function score was 54 (SD 20). Mean total TKR-related costs were US$30,831 (SD $9893). Multivariate regression analyses showed that increasing BMI and anxiety levels and decreasing levels of positive social interactions were associated with increased costs. A lower cost scenario with a lower range of normal BMI (19.5), highest positive social interaction, and no anxiety predicted TKR costs to be $22,247. Predicted costs in obese patients (BMI 36) with lowest positive social interaction and highest anxiety were $58,447. Increased baseline BMI, anxiety, and poor social support lead to higher TKR-related costs in patients with knee OA. Preoperative interventions targeting these factors may reduce TKR-related costs, and therefore be cost-effective.

    Borderline personality disorder (BPD) is characterized by antagonism, negative affectivity, disinhibition, and impairments in interpersonal functioning, including enhanced impulsive aggression. Interpersonal dysfunctions may be related to alterations in endocrine systems. The current study investigated alterations in basal activity of the hypothalamus-pituitary-gonadal (HPG) reproductive and the hypothalamus-pituitary-adrenal (HPA) stress system in BPD patients and their association to anger-related aggression with a particular focus on effects of gender and comorbid conditions of depression and posttraumatic stress disorder (PTSD). Saliva testosterone levels as well as cortisol awakening responses were assessed in 55 medication-free female and male patients with BPD and compared to 47 gender-, age-, and intelligence-matched healthy volunteers. In addition, analyses controlling for current depression and PSTD and bivariate correlations between testosterone and cortisol levels on the one hand and anger and aggressiveness on the other hand were performed. The results revealed increased saliva testosterone levels in female and male patients with BPD as well as elevated cortisol awakening responses in female, but not male patients with BPD compared to healthy volunteers. Cortisol awakening responses were positively related to anger and aggressiveness in female patients with BPD, but no associations were found with testosterone levels. In line with previous reports, the present results suggest endocrine alterations in BPD which may be associated with interpersonal impairments, such as increased anger-related aggressive behavior and could have implications for the development of new (psychopharmaco-) therapeutic interventions that may help to restore the alterations in the HPA and HPG systems.

    The segregation of DNA before cell division is essential for faithful genetic inheritance. In many bacteria, segregation of low-copy number plasmids involves an active partition system composed of a nonspecific DNA-binding ATPase, ParA, and its stimulator protein ParB. The ParA/ParB system drives directed and persistent movement of DNA cargo both in vivo and in vitro. Filament-based models akin to actin/microtubule-driven motility were proposed for plasmid segregation mediated by ParA. Recent experiments challenge this view and suggest that ParA/ParB system motility is driven by a diffusion ratchet mechanism in which ParB-coated plasmid both creates and follows a ParA gradient on the nucleoid surface. However, the detailed mechanism of ParA/ParB-mediated directed and persistent movement remains unknown. Here, we develop a theoretical model describing ParA/ParB-mediated motility. We show that the ParA/ParB system can work as a Brownian ratchet, which effectively couples the ATPase-dependent cycling of ParA-nucleoid affinity to the motion of the ParB-bound cargo. Paradoxically, this resulting processive motion relies on quenching diffusive plasmid motion through a large number of transient ParA/ParB-mediated tethers to the nucleoid surface. Our work thus sheds light on an emergent phenomenon in which nonmotor proteins work collectively via mechanochemical coupling to propel cargos-an ingenious solution shaped by evolution to cope with the lack of processive motor proteins in bacteria.

    Recently, rehabilitation therapists have become involved in cancer rehabilitation; however, no communication skills training that increases the ability to provide emotional support for cancer patients has been developed for rehabilitation therapists. In addition, no study has examined associations between rehabilitation therapists' communication skills and their level of autistic-like traits (ALT), which are in-born characteristics including specific communication styles and difficulty communicating with patients. In this study, we aimed to investigate whether confidence in communicating with patients mitigates communication difficulties experienced by rehabilitation therapists who have high levels of ALT. Rehabilitation therapists who treat patients with cancer completed self-administered postal questionnaires anonymously. Scores were obtained on the Autism-Spectrum Quotient short form, confidence in communication, and communication difficulties. We used covariance structure analyses to test hypothetical models, and confirmed that confidence in communication mediates the relationship between ALT and perceived communication difficulties. Participants included 1,343 respondents (49.6%). Autism-Spectrum Quotient scores were positively correlated with communication difficulties (r = 0.16, p confidence in communication in the fit model. However, higher confidence in creating a supportive atmosphere was associated with more difficulty in communication (r = 0.16, p Communication difficulty was linked to rehabilitation therapists' ALTs. By increasing confidence in areas of communication other than creation of a supportive atmosphere, ALT-related difficulties in communication may be ameliorated. Confidence to create supportive environments correlated positively with difficulty. Communication skills training to increase confidence in communication for rehabilitation therapists should be developed with vigilance regarding ALT levels.

    The purpose of this brief communication is to report the results of an analysis of maxillary premolar accessory ridges (MxPAR), a common but understudied accessory ridge that may occur both mesial and distal to the central ridge of the buccal cusp of upper premolars. We developed a new five-grade scoring plaque to better categorize MxPAR variation. Subsequently, we conducted a population analysis of MxPAR frequency in 749 dental casts of South African Indian, American Chinese, Alaskan Eskimo, Tohono O'odham (Papago), Akimel O'odham (Pima), Solomon Islander, South African Bantu, and both American and South African Whites. Northeast Asian and Asian-derived populations exhibited the highest MxPAR frequencies while Indo-European samples (South African Indians, American and South African Whites) exhibited relatively low frequencies. The Solomon Islanders and South African Bantu samples exhibited intermediate frequencies. Our analysis indicates that statistically significant differences in MxPAR frequency exist between major geographic populations. As a result, the MxPAR plaque has now been added to the Arizona State University Dental Anthropology System, an important contribution as maxillary premolar traits are underrepresented in analyses of dental morphology. 2009 Wiley-Liss, Inc.

    Personality researchers should modify models of traits to include mechanisms of differential reaction to situations. Whole Trait Theory does so via five main points. First, the descriptive side of traits should be conceptualized as density distributions of states. Second, it is important to provide an explanatory account of the Big 5 traits. Third, adding an explanatory account to the Big 5 creates two parts to traits, an explanatory part and a descriptive part, and these two parts should be recognized as separate entities that are joined into whole traits. Fourth, Whole Trait Theory proposes that the explanatory side of traits consists of social-cognitive mechanisms. Fifth, social-cognitive mechanisms that produce Big-5 states should be identified.

    Paternal age related schizophrenia (PARS) has been proposed as a subgroup of schizophrenia with distinct etiology, pathophysiology and symptoms. This study uses a k-means clustering analysis approach to generate hypotheses about differences between PARS and other cases of schizophrenia. We studied PARS (operationally defined as not having any family history of schizophrenia among first and second-degree relatives and fathers' age at birth ≥ 35 years) in a series of schizophrenia cases recruited from a research unit. Data were available on demographic variables, symptoms (Positive and Negative Syndrome Scale; PANSS), cognitive tests (Wechsler Adult Intelligence Scale-Revised; WAIS-R) and olfaction (University of Pennsylvania Smell Identification Test; UPSIT). We conducted a series of k-means clustering analyses to identify clusters of cases containing high concentrations of PARS. Two analyses generated clusters with high concentrations of PARS cases. The first analysis (N=136; PARS=34) revealed a cluster containing 83% PARS cases, in which the patients showed a significant discrepancy between verbal and performance intelligence. The mean paternal and maternal ages were 41 and 33, respectively. The second analysis (N=123; PARS=30) revealed a cluster containing 71% PARS cases, of which 93% were females; the mean age of onset of psychosis, at 17.2, was significantly early. These results strengthen the evidence that PARS cases differ from other patients with schizophrenia. Hypothesis-generating findings suggest that features of PARS may include a discrepancy between verbal and performance intelligence, and in females, an early age of onset. These findings provide a rationale for separating these phenotypes from others in future clinical, genetic and pathophysiologic studies of schizophrenia and in considering responses to treatment.

    A retrospective study has been performed in patients treated by iodine-131 for hyperthyroidism between April 1999 and February 2004..Among the 270 patients, 180 were more than 65 years old. After 65 years, hyperthyroidism is most often the consequence of a toxic adenoma or multi-nodular goiter while Graves' disease is most frequent in young patients. Iodine-131 is usually proposed as first line treatment in the elderly, at the opposite of young patients. With a mean follow-up of 12 months, return to euthyroidism is observed in 56.5% of the older patients and in 73.6% of the young patients. We explain this results by the lower incidence of Graves' disease in the elderly. Nuclear medicine physicians are legally obliged to provide patients with a proper information about radioprotection. Recommendations should nevertheless not induce overdue nor illegitimate fear. They should not only be written and standardized, but also given orally and adapted to each patient. Urinary incontinence is not specific to the old patients, but it is more frequent after 65. Collection and storage of contaminated waste is sometimes difficult and has often to be solved on a case by case basis. (author)

    Full Text Available Aim: To assess the prevalence of malocclusion, treatment needs and specific occlusal traits among Kolhapur population. Materials & Method: The sample comprised 500 individuals: that is, 250 boys & 250 girls between the age group of 13 -20 years. The sample was drawn from among the patients reporting for the treatment of malocclusion to the department. After intraoral examination, dental casts of the patients were assessed later and scored. A mouth mirror, a ruler & a sliding digital caliper was used. For every individual, variables related to malocclusion were recorded on a specially designed registration chart. A set of 10 photographs showing a range of dental attractiveness of the aesthetic component based on IOTN was followed and the data was subjected to statistical analysis. Results: About 48.80 % individuals had Angle′s Class I malocclusion; 34.60 % had Class II division 1; 2% had Class IT division 2 and 1.80% had Class Ill malocclusion. Deep-bite type of vertical malocclusion was present in 62.60% of the sample and 37.40% subjects had a normal overbite. The next most prevalent type of malocclusion was deviation of dental midlines which was found in 50.40% of sample. Orthodontic treatment need as assessed by the DHC of the IOTN were such that 24.20 %and 53.40% fell into grade 4 and grade 5 respectively. Therefore definitely requiring treatment and as assessed by the AC of the IOTN 27.40% and 18.20% sample fell into grades 8 - 10 and grade 10 respectively, as it was the least aesthetic arrangement of the dentition therefore definitely requiring treatment. Conclusions: Orthodontic treatment indices such as IOTN can be used effectively with less subjective bias to determine the orthodontic treatment need. The study suggests that there is a borderline to definite need for treatment in a large amount of population in the semirural western Maharashtra.

    Purpose. - Iodine 125 curietherapy is one of the conservative treatments of uveal melanoma. The technique used to achieve these results was simplified through the physical characteristics of the radioelement and the optimized-dosimetry program employed. Patients and methods. - 78 patients with choroidal melanoma were treated with iodine 125. About 100 Gy were delivered to the superior pole of the tumour. The minimal length of follow-up was 17 months and the average, 67 months. Results. -There was 88% local control, leading to lowered visual acuity in 76 % of the cases. Radiation retinopathy, directly related to proximity to the macula, is the principle etiology. Seven patients died of hepatic metastasis, five patients were enucleated. Four patients were further treated with proton-therapy to make up for non-control locally. Conclusion. -One dose of 100 Gy to the superior pole of the tumor seemed to lead to good local control, with the exception of complications related to proximity to the macula and the optic nerve. In this attempt to optimize irradiation, the time lapse between any benefit in local control derived from irradiation and post-therapeutic complications observed remains insufficient to evaluate any relationship.

    Full Text Available OBJECTIVE: To examine the relationship between sagittal balance parameters and different symptoms of spinal disease in patients with lumbar canal stenosis (LCS and controls. METHODS: In this prospective, diagnostic, case-control study, we included all patients consecutively admitted to a public teaching hospital for surgical treatment of LCS between July 2010 and October 2011, aged more than 40 years, with back pain plus radiculopathy or neurogenic claudication, and controls without LCS. Magnetic resonance and x-rays allowed the measurement of sagittal axis parameters. Clinical data, the Oswestry Disability Index and the visual analogue scale of pain were assessed. RESULTS: 23 patients were in the Stenosis group, and 17 were controls. The Stenosis group presented lower values of total lumbopelvic lordosis and regional lordosis L1, L2 and L3. In LCS patients and back pain, total lumbopelvic and regional lordosis at L1, L2 and L3 were smaller. Those with stenosis and radiculopathy had higher values of pelvic tilt and lower total lumbopelvic lordosis and regional lordosis in L1 and L2. In patients with claudication, regional lumbopelvic lordosis in L1 and L2 and the T9 sagittal offset were smaller. All patients with pain had higher values of thoracic kyphosis, regional lumbopelvic lordosis in L1, lower values for pelvic tilt, sagittal T1 offset, sacro-femoral distance and overhang compared to patients without pain. CONCLUSIONS: This study shows significant correlations between symptoms and sagittal axis parameters between patients with and without spinal canal stenosis and also in subgroups of the patients with stenosis with different complaints.OBJETIVO: Analizar la relación entre los parámetros del equilibrio sagital y los diversos síntomas de enfermedad espinal en pacientes con estenosis del canal lumbar (ECL y sus controles.

  18. Par Pond vegetation status Summer 1995 -- Summary

    International Nuclear Information System (INIS)

    Mackey, H.E. Jr.; Riley, R.S.

    1996-01-01

    The water level of Par Pond was lowered approximately 20 feet in mid-1991 in order to protect downstream residents from possible dam failure suggested by subsidence on the downstream slope of the dam and to repair the dam. This lowering exposed both emergent and nonemergent macrophyte beds to drying conditions resulting in extensive losses. A survey of the newly emergent, shoreline aquatic plant communities of Par Pond began in June 1995, three months after the refilling of Par Pond to approximately 200 feet above mean sea level. These surveys continued in July, September, and late October, 1995. Communities similar to the pre-drawdown, Par Pond aquatic plant communities are becoming re-established. Emergent beds of maidencane, lotus, waterlily, and watershield are extensive and well developed. Cattail occurrence continued to increase during the summer, but large beds common to Par Pond prior to the drawdown have not formed. Estimates from SPOT HRV, remote sensing satellite data indicated that as much as 120 hectares of emergent wetlands vegetation may have been present along the Par Pond shoreline by early October, 1995. To track the continued development of macrophytes in Par Pond, future surveys throughout 1996 and 1997, along with the continued evaluation of satellite data to map the areal extent of the macrophyte beds of Par Pond, are planned

    Full Text Available The aim of the present study is to establish the results using the scores obtained from the methodology that was applied for assessing the stability after 2 years post orthodontic treatment and stability in a sample of 69 individuals. After applying PAR index to the collected group of patients, a series of scores were obtained, which were then needed to be evaluated further to establish the results. The scores were evaluated using the nomogram. A comparison was done between the post treatment and the 2 years post treatment PAR weighting scores to determine if the results were stable after orthodontic treatment.

    Personality traits like depression on the one hand and aggression and impulsivity on the other are assumed to be predisposing factors for different types of alcohol dependence. Both types are associated with sensitivity to frustration, but this may be different for the two types of personality according to whether they are confronted with frustrations caused by withdrawal from positive or infliction of negative events. It has not been shown so far if both types of personality factors and the two different sources of frustration are differently relevant for the propensity of relapse. This was investigated here in a study on 60 abstinent male alcohol-dependent patients. Correlations between the number of previous detoxifications reflecting liability to relapse and questionnaire scores on personality factors and on reactions to frustration were computed. Bonferroni-corrected correlations yielded significant relationships between the number of detoxifications and the personality factor of aggression as well as pronounced depressive reactions to frustrating conditions of non-reward caused by humans. Controlling for impulsivity, aggression and depression revealed that depressive reactions to frustration are genuine predictors for probability of relapse independent of underlying personality factors. Persons particularly sensitive to frustrations from human denial of positive reinforcers are liable to relapse which fits the theory of sensitivity to reward in drug-addicted individuals. Results demonstrate that relapse is clearly more related to aggression than to impulsivity, depression and anxiety and may be facilitated if persons are sensitive to frustrating conditions of non-reward caused by social partners.

    Full Text Available Abstract The 5HT1A receptor is one of at least 14 different receptors for serotonin which has a role in moderating several brain functions and may be involved in the aetiology of several psychiatric disorders. The C(-1019G 5-HT1A promoter polymorphism was reported to be associated with major depression, depression-related personality traits and suicidal behavior in various samples. The G(-1019 allele carriers are prone to depressive personality traits and suicidal behavior, because serotonergic neurotransmission is reduced. The aim of this study is to replicate previous findings in a sample of 185 Alcohol-dependent individuals. Personality traits were evaluated using the NEO FFI and TCI. History of suicidal behavior was assessed by a standardized semistructured interview (SSAGA. No significant differences across C(-1019G 5-HT1A genotype groups were found for TCI temperament and character traits and for NEO FFI personality scales. No association was detected between this genetic variant and history of suicide attempts. These results neither support a role of C(-1019G 5-HT1A promoter polymorphism in the disposition of personality traits like harm avoidance or neuroticism, nor confirm previous research reporting an involvement of the G allele in suicidal behavior in alcoholics. Significant associations, however, were detected between Babor's Type B with number of suicide attempts in history, high neuroticism and harm avoidance scores in alcoholics.

    Instability can develop after lumbar spinal surgery. What is also known as secondary segmental instability is one of the important causes of failed back syndrome. In this paper, we described a 45-year-old female patient who was diagnosed with secondary segmental instability caused by left L3 pars interarticularis fracture after a high lumbar disc surgery and was subsequently treated with re-operation. We evaluated the clinical course, diagnosis, and treatment methods for secondary segmental instability caused by postoperative pars interarticularis fracture. Furthermore, we emphasized the importance of preserving the pars interarticularis during upper lumbar disc surgeries in order to avoid a potential stress fracture.

    The goal of this prospective study is establishing the evolution and long term prognostication in chronic ethylic patients afflicted with severe cardiac insufficiency (CI), presenting a dilated cardiomyopathy (DCM). Forty patients (average age 44.8 {+-} 9.2 years) are consecutively included according to the following criteria: CI (stage IV), DCM without definite etiology, chronic alcoholism during more than 10 years and superior to 80 g alcohol/day. The telediastolic diameter (TDD) of left ventricle viewed by echo-cardiogram is increased up to 68.4 {+-} 3.6 mm with a fraction of shortening (FS) of 14.2 {+-} 3.7%. The isotopic ejection fraction (EF) is lowered down to 21.6 {+-} 5.9%. All the patients received a conventional treatment of CI while the abstinence was hardly urged. Three patients recurred and subsequently refused the follow-up. By the third month, in absence of any amelioration, a patient benefited by a cardiac transplant and another patient deceased after myocardial biopsy. Nine patients benefited by a complete follow-up of 36 months. After the third month the functional amelioration is notable and confirmed by different parameters: TDD of 64.3 {+-} 3.6 (p < 0.02), FS of 18.8 {+-} 7.2% (NS) and EF of 31.3 {+-} 11.1% (p < 0.03). The amelioration of different criteria is significant by the 6. month and than stabilizes itself up to 3 years as showed by the EF evolution curves. In conclusion, the prognostication of these patients with severe CI is favorable. The functional amelioration is precocious and confirmed by the different ventricular parameters studied. The medical treatment associated with a complete and definitive abstinence is the key of success

    Mammalian target of rapamycin complex 2 (mTORC2) has been identified as a major regulator of bladder cancer cell migration and invasion. Upstream pathways that mediate mTORC2 activation remain poorly defined. Urokinase-type plasminogen activator receptor (uPAR) is a GPI-anchored membrane protein and known activator of cell-signaling. We identified increased uPAR expression in 94% of invasive human bladder cancers and in 54-71% of non-invasive bladder cancers, depending on grade. Normal urothelium was uPAR-immunonegative. Analysis of publicly available datasets identified uPAR gene amplification or mRNA upregulation in a subset of bladder cancer patients with reduced overall survival. Using biochemical approaches, we showed that uPAR activates mTORC2 in bladder cancer cells. Highly invasive bladder cancer cell lines, including T24, J82 and UM-UC-3 cells, showed increased uPAR mRNA expression and protein levels compared with the less aggressive cell lines, UROtsa and RT4. uPAR gene-silencing significantly reduced phosphorylation of Serine-473 in Akt, an mTORC2 target. uPAR gene-silencing also reduced bladder cancer cell migration and Matrigel invasion. S473 phosphorylation was observed by immunohistochemistry in human bladder cancers only when the tumors expressed high levels of uPAR. S473 phosphorylation was not controlled by uPAR in bladder cancer cell lines that are PTEN-negative; however, this result probably did not reflect altered mTORC2 regulation. Instead, PTEN deficiency de-repressed alternative kinases that phosphorylate S473. Our results suggest that uPAR and mTORC2 are components of a single cell-signaling pathway. Targeting uPAR or mTORC2 may be beneficial in patients with bladder cancer. Copyright © 2016. Published by Elsevier Inc.

    Despite the fact that new criteria of antisocial personality disorder (ASPD) in diagnostic and statistical manual of mental disorders-fifth edition (DSM-5) were resulted from five-factor model (FFM), there is a small amount of studies that investigate the relations between proposed personality traits and FFM. Also, cross-cultural study in this field continuously would be needed. The aim of the present study was to evaluate the relation between the FFM and DSM-5 ASPD pathological traits. This study was a cross-sectional study design. The participants consisted of 122 individuals with ASPD that selected from prisoners (73.0%), outpatients (18.0%), and inpatients (9.0%). They were recruited from Tehran Prisoners, and Clinical Psychology and Psychiatry Clinics of Razi and Taleghani Hospitals, Tehran, Iran, since 2013-2014. The Sample was selected based on judgmental sampling.

    Childhood traumas appear to be linked to suicidal behavior. However, the factors that mediate between these two phenomena are not sufficiently understood. Recent findings suggest that borderline personality disorder (BPD) may explain some of the association. The present study investigated the potential mediating role of BPD symptomatology and traits between reported childhood trauma and suicidal risk in adult psychiatric outpatients ( N  = 124). BPD symptomatology was measured with DSM-5 Section II criterion-counts (SCID-II; Structured Clinical Interview for DSM-IV Axis II), whereas BPD traits were measured with specified DSM-5 Section III traits (PID-5; Personality Inventory for DSM-5). Childhood traumas were self-reported (CTQ; Childhood Trauma Questionnaire), whereas level of suicidal risk was measured with a structured interview (MINI Suicidality Module; Mini International Neuropsychiatric Interview). Mediation effects were tested by bias-corrected (10.000 boot-strapped samples) confidence intervals. BPD features account for a considerable part of the cross-sectional association between childhood trauma and level of suicidal risk, even when controlling for the influence of gender, age, and educational level. This finding remained stable when testing the model without the suicidality-related BPD criterion and PID-5 items. DSM-5 Section II BPD criterion-counts explained 67% of the total effect, whereas DSM-5 Section III BPD traits accounted for 82% of the total effect. The specific DSM-5 Section III trait facets of "Depressivity" (52%) and "Perceptual Dysregulation" (37%) accounted for most of this effect. The findings provide preliminary support for the proposed mediation model indicating that BPD features may help explain relations between childhood trauma and elevated suicidal risk in adult life, in particular for DSM-5 Section III personality traits of depressivity (e.g., pessimism, guilt, and shame) and perceptual dysregulation (e.g., dissociation).

    Progression of melanoma is dependent on cross-talk between tumor cells and the adjacent microenvironment. The thrombin receptor, protease-activated receptor-1 (PAR-1), plays a key role in exerting this function during melanoma progression. PAR-1 and its activating factors, which are expressed on tumor cells and the surrounding stroma, induce not only coagulation but also cell signaling, which promotes the metastatic phenotype. Several adhesion molecules, cytokines, growth factors, and proteases have recently been identified as downstream targets of PAR-1 and have been shown to modulate interactions between tumor cells and the microenvironment in the process of melanoma growth and metastasis. Inhibiting such interactions by targeting PAR-1 could potentially be a useful therapeutic modality for melanoma patients. ©2011 AACR.

    To evaluate the diagnostic utility of Hep par-1 in differentiating hepatocellular carcinoma from metastatic carcinoma taking histopathology as a gold standard. Study Design: Comparative cross-sectional study. Place and Duration of Study: Pathology Department, Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from April 2007 to February 2008. Methodology: Hep par-1 immunohistochemical stain was performed on 60 cases of liver carcinoma, 30 cases each of metastatic and hepatocellular carcinoma. Information regarding patient age, gender, sign and symptoms, radiographic findings, histological grade of tumour, and expression of Hep par-1 on hepatocellular and metastatic carcinoma were recorded on proforma sheet. Sensitivity, specificity, positive and negative predictive values, and accuracy of Hep par-1 were calculated using the formulas. Results: Hep par-1 expression was noted in 25 out of 30 cases of hepatocellular carcinoma (83%). Out of 30 cases of metastatic carcinoma, only one case expressed staining in < 5% tumour cells and remaining 29 cases showed no reactivity. The age of the patients with hepatocellular carcinoma ranged from 40 to 76 years with a median age of 60.5 years and 40 - 75 years for metastatic carcinomas with a median age of 57.5 years. Conclusion: Hep par-1 is a reliable immunohistochemical marker for cases of hepatocellular carcinoma (HCC). It can be used along with other markers in morphologically difficult cases when differential diagnosis lies between poorly differentiated HCC and metastatic carcinoma of liver. (author)

    Objective To investigate the correlation between disability acceptance and personality trait in patients with cerebral infarction, so as to provide a new perspective to improve the disability acceptance. Methods A total of 205 patients with cerebral infarction were investigated by the Acceptance of Disability Scale and the Eysenck Personality Questionnaire-revised-Short Scale for Chinese( EPQ-RSC) . The level of personality trait in patients was compared with the norm, and the Pearson correlation analysis and hierarchical regression analysis were used to explore the effect of personality trait on the disability acceptance. Results The total score of disability acceptance was (128. 08 ± 28. 89) in patients, and 57. 07% of them (117/205) were in the low level, 27. 80% of them (57/205) were in the medium level, 15. 13% of them (31/205) were in the high level. The level of neuroticism, psychoticism and lie in personality trait were significantly higher than those of the norm (t=4. 143,12. 622, 6. 604, respectively;P<0. 01). The level of introvert or extrovert character in personality trait was significantly lower than that in the normal population (t= -9. 552,P<0. 01). Pearson correlation analysis showed that each factor of disability acceptance was significantly negatively correlated with the scores of neuroticism, psychoticism and dissimulation in personality trait (r= -0. 436 0. 025,P<0. 05), but significantly positively correlated with the score of introvert or extrovert character in personality trait ( P<0. 05). Hierarchical regression analysis showed that dissimulation, introvert or extrovert character and neuroticism in personality trait could explained 30. 50% of the total variance of disability acceptance in patients with cerebral infarction (P <0. 05). Conclusions The level of disability acceptance is in the low level in cerebral infarction patients, and personality trait is the influencing factor.

    This study aims at testing the hypothesis that the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) alternative model of personality disorder (AMPD) traits may be significantly associated with deficits on 2 different social cognition tasks, namely, the Reading the Mind in the Eyes Test and the Movie for the Assessment of Social Cognition, in a sample of consecutively admitted inpatients and outpatients. The sample was composed of 181 consecutively admitted participants (57.5% women; mean age = 38.58 years). Correlation coefficients and partial correlation coefficients were computed in order to assess the associations among social cognition tasks, DSM-5 AMPD traits, and dimensionally assessed DSM-5 Section II personality disorders. Specific maladaptive traits listed in the DSM-5 AMPD were significantly associated with Reading the Mind in the Eyes Test scores and Movie for the Assessment of Social Cognition scores, even when the effect of selected DSM-5 Section II personality disorders was controlled for. Our results support the relevance of studying social cognitive functioning in subjects suffering from personality disorders. Copyright © 2017 John Wiley & Sons, Ltd.

  9. Same Traits, Different Variance

    Full Text Available Personality trait questionnaires are regularly used in individual differences research to examine personality scores between participants, although trait researchers tend to place little value on intra-individual variation in item ratings within a measured trait. The few studies that examine variability indices have not considered how they are related to a selection of psychological outcomes, so we recruited 160 participants (age M = 24.16, SD = 9.54 who completed the IPIP-HEXACO personality questionnaire and several outcome measures. Heterogenous within-subject differences in item ratings were found for every trait/facet measured, with measurement error that remained stable across the questionnaire. Within-subject standard deviations, calculated as measures of individual variation in specific item ratings within a trait/facet, were related to outcomes including life satisfaction and depression. This suggests these indices represent valid constructs of variability, and that researchers administering behavior statement trait questionnaires with outcome measures should also apply item-level variability indices.

    Full Text Available Background: The purpose of this study was to assess the arterial stiffness (AS in black africans patients with systemic scleroderma. Patients and Methodology: A prospective cross-sectional hospital survey has been performed over a 6-month period, including 55 black african individuals, aged over 16 years and consenting, consisting of 29 patients with systemic scleroderma and 26 hospitalized controls. The finger-toe pulse wave velocity (ft-PWV was recorded by popmetre® and comparaison between the 2 groups has been performed with statistical analysis. Results: The mean ft-PWV was 9,56 m/s ± 3,09 in the patient group and 7,71 m/s ± 2,63 in control group. The ft-PWV was significantly higher in patients with scleroderma compared to controls (p<0.0145. The study of the relationship between AS and independent variables in multivariate analysis demonstrated that having scleroderma increase by 1.81 times the value of the ft-PWV after adjustment for age and systolic blood pressure. Discussion: To our knowledge, this is the first assessment of the AS in black african patients with scleroderma. It shows that ft-PWV was significantly higher in patients with scleroderma compared to controls. Also, this high AS was imputable to the scleroderma. Conclusion: In Africa, the measurement of the AS by popmetre® could be a simple, rapid, non invasive and pratical early detection and follow-up of cardio-vascular involvments in the course of scleroderma.

    Full Text Available Autistic traits can help people gain and sustain power, and has probably done so throughout history, says the present paper. A number of testable claims follow from this assumption. First, the powerful should have more autistic traits than others – which they do appear to have. Among other things, powerful people, and those with many autistic traits, tend to prefer solitary activities and are often aloof. Moreover, they are often rigid and socially insensitive, low on empathy and with low scores on the trait of agreeableness -- and as a rule they do not have many friends. Both groups are also more self-centered than others, more honest, less submissive, more sensitive to slights, and with a stronger tendency to engage in abstract thinking. They tend to behave in bossy or dominant ways, and their moral judgment is more based on rules than on feelings. In addition to experimental evidence, I cite biographies showing that a surprising number of presidents, prime ministers and other powerful people seem to have had traits like those in question – and interestingly, in animals, leaders are often rigid and insensitive to group members’ needs and feelings, mostly acting the way they are themselves inclined to, not responding much to others. Problem solving is important in leadership, and people with many autistic traits appear often to be better thinkers than typical subjects with similar IQs. However, these and other congruities could be coincidences. Hence the question of whether traits the two groups have in common also have a common cause constitutes a strong test of the paper’s thesis – and a common cause does appear to exist, in the form of testosterone’s effects on the central nervous system. Finally, there is evidence that, other things equal, powerful men have more reproductive success than others.

    To study the incidence of endophthalmitis after pars plana vitrectomy, its causative organisms, and visual acuity outcomes. In this retrospective, comparative study, the medical records of patients with acute-onset postoperative endophthalmitis after pars plana vitrectomy at Farabi Eye Hospital, Tehran, Iran, during a 12-year period between January 2004 and November 2015 were reviewed. To compare the endophthalmitis patients with other cases who underwent pars plana vitrectomy at the same day and also the same operating room, a control group was developed by gathering the data from surgical records. In the present study, the incidence rate of pos- vitrectomy endophthalmitis was 0.04% (16/39783). The organisms identified in aqueous or vitreous cultures (culture positive 44%) included Streptococcus pneumoniae (two patients, 12.5%), Pseudomonas aeruginosa (two patients, 12.5%), fungi (two patients, 12.5%), and Streptococcus viridans (one patient, 6.25%). Visual acuity after treatment for endophthalmitis ranged from light perception (7 eyes) to hand motion (1 eye), and evisceration was performed in 8 eyes (50%). When comparing the cases (patients developing endophthalmitis) and controls (patients with no complications operated in the same day and place of operation with the case group), only not using tamponade showed a statistically significant relation with the occurrence of endophthalmitis (p = 0.034). Our results indicated low incidence of endophthalmitis after pars plana vitrectomy comparable to previous studies which resulted in poor visual acuity. It seems that not using tamponade might increase the risk of endophthalmitis among these patients.

  18. Fear inhibition in high trait anxiety.

    Directory of Open Access Journals (Sweden)

    Merel Kindt

    Full Text Available Trait anxiety is recognized as an individual risk factor for the development of anxiety disorders but the neurobiological mechanisms remain unknown. Here we test whether trait anxiety is associated with impaired fear inhibition utilizing the AX+/BX- conditional discrimination procedure that allows for the independent evaluation of startle fear potentiation and inhibition of fear. Sixty undergraduate students participated in the study--High Trait Anxious: n = 28 and Low Trait Anxious: n = 32. We replicated earlier findings that a transfer of conditioned inhibition for startle responses requires contingency awareness. However, contrary to the fear inhibition hypothesis, our data suggest that high trait anxious individuals show a normal fear inhibition of conditioned startle responding. Only at the cognitive level the high trait anxious individuals showed evidence for impaired inhibitory learning of the threat cue. Together with other findings where impaired fear inhibition was only observed in those PTSD patients who were either high on hyperarousal symptoms or with current anxiety symptoms, we question whether impaired fear inhibition is a biomarker for the development of anxiety disorders.

    Traditional personality disorders (PDs) are associated with significant psychosocial impairment. DSM-5 Section III includes an alternative hybrid personality disorder (PD) classification approach, with both type and trait elements, but relatively little is known about the impairments associated with Section III traits. Our objective was to study the incremental validity of Section III traits--compared to normal-range traits, traditional PD criterion counts, and common psychiatric symptomatology--in predicting psychosocial impairment. To that end, 628 current/recent psychiatric patients completed measures of PD traits, normal-range traits, traditional PD criteria, psychiatric symptomatology, and psychosocial impairments. Hierarchical regressions revealed that Section III PD traits incrementally predicted psychosocial impairment over normal-range personality traits, PD criterion counts, and common psychiatric symptomatology. In contrast, the incremental effects for normal-range traits, PD symptom counts, and common psychiatric symptomatology were substantially smaller than for PD traits. These findings have implications for PD classification and the impairment literature more generally.

    Personality traits are multidimensional traits comprising cognitive, emotional, and behavioral characteristics, and a wide array of cerebral structures mediate individual variability. Differences in personality traits covary with brain morphometry in specific brain regions. A cerebellar role in emotional and affective processing and on personality characteristics has been suggested. In a large sample of healthy subjects of both sexes and differently aged, the macro- and micro-structural variations of the cerebellum were correlated with the scores obtained in the Temperament and Character Inventory (TCI) by Cloninger. Cerebellar volumes were associated positively with Novelty Seeking scores and negatively with Harm Avoidance scores. Given the cerebellar contribution in personality traits and emotional processing, we investigated the cerebellar involvement even in alexithymia, construct of personality characterized by impairment in cognitive, emotional, and affective processing. Interestingly, the subjects with high alexithymic traits had larger volumes in the bilateral Crus 1. The cerebellar substrate for some personality dimensions extends the relationship between personality and brain areas to a structure up to now thought to be involved mainly in motor and cognitive functions, much less in emotional processes and even less in personality individual differences. The enlarged volumes of Crus 1 in novelty seekers and alexithymics support the tendency to action featuring both personality constructs. In fact, Novelty Seeking and alexithymia are rooted in behavior and inescapably have a strong action component, resulting in stronger responses in the structures more focused on action and embodiment, as the cerebellum is.

    The soluble form of urokinase-type plasminogen activator receptor (suPAR) is a new inflammatory marker. High suPAR levels have been shown to associate with mortality in cancer and in chronic infections like HIV and tuberculosis, but reports on the role of suPAR in acute bacteremic infections...... are scarce. To elucidate the role of suPAR in a common bacteremic infection, the serum suPAR levels in 59 patients with Staphylococcus aureus bacteremia (SAB) were measured using the suPARnostic ELISA assay and associations to 1-month mortality and with deep infection focus were analyzed. On day three, after...... the first positive blood culture for S. aureus, suPAR levels were higher in 19 fatalities (median 12.3; range 5.7-64.6 ng/mL) than in 40 survivors (median 8.4; range 3.7-17.6 ng/mL, p = 0.002). This difference persisted for 10 days. The presence of deep infection focus was not associated with elevated su...

    Previous studies have indicated that a parental rearing style showing a low level of care on the parental bonding instrument (PBI) is a risk factor for depression, and that there is a relationship between the overprotective rearing style on the PBI and obsessive-compulsive disorder (OCD). However, there is no study on the parental rearing attitudes in depressive patients divided into two groups based on their obsessive traits. In this study, we evaluated the parental rearing attitudes and examined the differences among four groups: depressive patients with severe obsessive traits, depressive patients with mild obsessive traits, OCD patients, and healthy volunteers. We divided the depressive patients into severe and mild groups based on their obsessive traits on the Mausdley Obsessional-Compulsive Inventory (MOCI). We compared PBI scores among four groups of 50 subjects matched for age and sex: depressive patients with severe obsessive traits, depressive patients with mild obsessive traits, OCD patients, and healthy volunteers. The paternal protection scores in the depressive patients with severely obsessive traits and the OCD patients were significantly higher than those in the depressive patients with mildly obsessive traits and healthy volunteers. This study indicated that the depressive patients with severe obsessive traits and the OCD patients have similar paternal controlling and interfering rearing attitudes. We conclude that the paternal controlling and interfering rearing attitudes are linked to the development of OCD and depression with obsessive traits, and are not linked to the development of depression itself.

    To evaluate the demographic characteristics, clinical features, treatment and outcomes of patients with pars planitis in a tertiary referral center in Turkey. Medical records of patients with pars planitis were retrospectively reviewed. The data including demographic and ocular features and treatment outcomes were recorded. The distribution of clinical findings and complications were evaluated according to age and gender groups. The changes in final BCVA compared to the initial BCVA were noted. Statistical analysis was performed using SPSS software (Version 18.0, SPSS Inc., Chicago, USA). Twenty-seven patients (54 eyes) were included in this study. 16 patients were male (59.3%), and 11 were female (40.7%). Mean age at diagnosis was 12.84 ± 8.26 (range 4-36) years. Mean follow-up period was 61.3 ± 52.15 (range 9-172) months. Mean BCVA was 0.58 ± 0.36 (range 0.03-1.00) (0.40 ± 0.45 logMAR) at presentation, and 0.81 ± 0.28 (range 0.10-1.00) (0.14 ± 0.27 logMAR) at final visit (P = 0.001). Vitreous inflammation (100%), vitreous haze (92.6%), snowballs (74.1%), snowbanks (66.7%), anterior chamber cells (66.7%) and peripheral retinal vascular sheathing (48.1%) were the most common presentations. Ocular complications included vitreous condensation (51.9%), cystoid macular edema (22.2%), cataract (18.5%), inferior peripheral retinal detachment (11.1%), glaucoma (5.6%) and vitreous hemorrhage (3.7%). Treatments included topical, periocular, intravitreal and systemic corticosteroids, immunosuppressives, peripheral laser photocoagulation and pars plana vitrectomy when needed. Pars planitis is an idiopathic chronic intermediate uveitis mostly affecting children and adolescents. In spite of its chronic nature with high potential of causing ocular complications, adequate treatment and close follow-up lead to favorable visual outcomes.

    In Denmark 8,000 to 10,000 people will attempt suicide each year. The Centre of Excellence in Suicide Prevention in the Capital Region of Denmark is treating patients with suicidal behavior, and a recent survey has shown that 30% of the patients are suffering from borderline personality disorder. The majority of patients (70% to 75%) with borderline personality disorder have a history of deliberate self-harm and 10% have a lifetime risk to die by suicide. The DiaS trial is comparing dialectical behavior therapy with collaborative assessment and management of suicidality-informed supportive psychotherapy, for the risk of repetition of deliberate self-harm in patients with a recent suicide attempt and personality traits within the spectrum of borderline personality disorder. Both treatments have previously shown effects in this group of patients on suicide ideation and self-harm compared with treatment as usual. The trial is designed as a single-center, two-armed, parallel-group observer-blinded randomized clinical superiority trial. We will recruit 160 participants with a recent suicide attempt and at least two traits of the borderline personality disorder from the Centre of Excellence in Suicide Prevention, Capital Region of Denmark. Randomization will be performed though a centralized and computer-generated approach that conceals the randomization sequence. The interventions that are offered are a modified version of a dialectical behavior therapy program lasting 16 weeks versus collaborative assessment and management of suicidality-informed supportive psychotherapy, where the duration treatment will vary in accordance with established methods up to 16 weeks. The primary outcome measure is the ratio of deliberate self-harming acts including suicide attempts measured at week 28. Other exploratory outcomes are included such as severity of symptoms, suicide intention and ideation, depression, hopelessness, self-esteem, impulsivity, anger, and duration of respective

    In unicellular bacteria, the ParA and ParB proteins segregate chromosomes and coordinate this process with cell division and chromosome replication. During sporulation of mycelial Streptomyces, ParA and ParB uniformly distribute multiple chromosomes along the filamentous sporogenic hyphal compartment, which then differentiates into a chain of unigenomic spores. However, chromosome segregation must be coordinated with cell elongation and multiple divisions. Here, we addressed the question of whether ParA and ParB are involved in the synchronization of cell-cycle processes during sporulation in Streptomyces. To answer this question, we used time-lapse microscopy, which allows the monitoring of growth and division of single sporogenic hyphae. We showed that sporogenic hyphae stop extending at the time of ParA accumulation and Z-ring formation. We demonstrated that both ParA and ParB affect the rate of hyphal extension. Additionally, we showed that ParA promotes the formation of massive nucleoprotein complexes by ParB. We also showed that FtsZ ring assembly is affected by the ParB protein and/or unsegregated DNA. Our results indicate the existence of a checkpoint between the extension and septation of sporogenic hyphae that involves the ParA and ParB proteins. PMID:27248800

    Salivary α-amylase (sAA) activity alternations are observed in major depressive disorder (MDD) being associated with depression severity and its specific psychopathological dimensions with anxiety being attributed to distress. No data is available on sAA in MDD according to Hamilton Rating Scale for Depression (HAMD-17) and State-Trait Anxiety Inventory (STAI). The exploratory study examines whether and to what extent baseline sAA level is interrelated to the psychopathological features including severity of symptoms and specific psychopathological dimensions. The basal, non-stimulated sAA activity was studied in 20 non-late-life adult, treatment-naïve MDD patients with short-illness-duration and in 20 age- and sex-matched healthy controls along with psychometric assessments with Hamilton Rating Scale for Depression (HAMD-17) and Spielberger State-Trait Anxiety Inventory (STAI). Significantly lower ( p =0.011) sAA activity was observed in MDD as compared to controls. No significant correlations were observed between sAA activity and the total HAMD-17 score as well as with regard to the specific core depression, insomnia, anxiety and somatic HAM-D psychopathological dimensions. No significant correlations were also found between sAA and STAIX-1 and STAIX-2 scores. Low baseline sAA levels in MDD with no correlations between sAA and psychopathological features including severity of symptoms and specific psychopathological dimensions was found. Key words: Salivary alpha-amylase, major depressive disorder, Spielberger State-Trait Anxiety Inventory, Hamilton Rating Scale for Depression.

    A first-in-human clinical trial with Positron Emission Tomography (PET) imaging of the urokinase-type plasminogen activator receptor (uPAR) in patients with breast, prostate and bladder cancer, is described. uPAR is expressed in many types of human cancers and the expression is predictive of invasion, metastasis and indicates poor prognosis. uPAR PET imaging therefore holds promise to be a new and innovative method for improved cancer diagnosis, staging and individual risk stratification. The uPAR specific peptide AE105 was conjugated to the macrocyclic chelator DOTA and labeled with 64Cu for targeted molecular imaging with PET. The safety, pharmacokinetic, biodistribution profile and radiation dosimetry after a single intravenous dose of 64Cu-DOTA-AE105 were assessed by serial PET and computed tomography (CT) in 4 prostate, 3 breast and 3 bladder cancer patients. Safety assessment with laboratory blood screening tests was performed before and after PET ligand injection. In a subgroup of the patients, the in vivo stability of our targeted PET ligand was determined in collected blood and urine. No adverse or clinically detectable side effects in any of the 10 patients were found. The ligand exhibited good in vivo stability and fast clearance from plasma and tissue compartments by renal excretion. In addition, high uptake in both primary tumor lesions and lymph node metastases was seen and paralleled high uPAR expression in excised tumor tissue. Overall, this first-in-human study therefore provides promising evidence for safe use of 64Cu-DOTA-AE105 for uPAR PET imaging in cancer patients. PMID:26516369

    The aim of this study is to examine the relationship between lumbar lordosis and pars interarticularis fractures. In this retrospective case-control study we compare the angle of lumbar lordosis and the angle of the S1 vertebral endplate (as a measure of pelvic tilt) in patients with bilateral L5 pars interarticularis fractures with age- and sex-matched control cases with normal MRI examinations of the lumbar spine. Twenty-nine cases of bilateral L5 pars interarticularis fractures with matched control-cases were identified on MRI (16 male, 13 female, age 9-63 years). The angle of lordosis was measured between the inferior L4 and superior S1 vertebral endplates on a standing lateral lumbar spine radiograph for both groups. The mean angle of lordosis about the L5 vertebra was 36.9 (SD = 6.5 ) in the pars interarticularis fracture group, and 30.1 (SD = 6.4 ) in the control group. The difference between the two groups was significant (mean difference 6.8 , Student's t test: P < 0.001). The mean angle of sacral tilt measured was 122.2 (SD = 10.16 ) for controls and 136.4 (SD = 10.86 ) for patients with pars defects. The difference in the means of 14.2 was statistically significantly different (P < 0.0001). Sacral tilt represented by a steeply angled superior endplate of S1 is associated with a significantly increased angle of lordosis, between L4 and S1, and pars fractures at L5. Steep angulation of the first sacral vertebral segment maybe the predisposing biomechanical factor that leads to pincer-like impingement of the pars interarticularis and then spondylolysis. (orig.)

    Treatment of primary focal segmental glomerulosclerosis (FSGS) and its recurrence after kidney transplantation associated with rapid deterioration of kidney function remains to be challenging despite advances in immunosuppressive therapy. The presence of circulating factors has been postulated to be a pivotal player in the pathogenesis of FSGS, although suPAR and CLCF-1 have been identified as the most promising causative factors. The potential therapeutic effect of suPAR elimination in an FSGS patient using CytoSorb, a hemoadsorption device that gained attention in the cytokine elimination in septic patients, was studied. Efficiency of total plasma exchange to remove suPAR was determined. CytoSorb hemoadsorption caused a 27.33% reduction of the suPAR level in a single treatment, whereas total plasma exchange showed a suPAR level reduction of 25.12% (n = 3; 95% confidence interval, 0.2777-0.8090; P < 0.01), which may indicate therapeutic potential in the treatment of primary FSGS and its recurrence in a kidney transplant. © 2017 Wiley Periodicals, Inc.

    2010-01-01

    Thalassaemia syndromes are a group of hereditary disorders characterised by a genetic deficiency in the synthesis of --globin genes. The objective of this study was to determine the haematological features -thalassaemia trait (BTT), and to determine the sensitivity of Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and -thalassaemia trait. Methods: A descriptive study was conducted in Hayatabad Medical Complex, Peshawar from May 2009 to May 2010 with 203 subjects having BTT. Blood samples were collected in EDTA anti-coagulated tubes. RBC indices were taken as part of complete blood count (CBC) by haematology analyser, and Haemoglobin (Hb) electrophoresis was done to determine the HbA2 percentage. The data was collected and analyzed on statistical software for demographic details, RBC indices and HBA2 levels. Results: Out of 203 patients, 92 (45%) were males and 111 (55%) were females. Most patients tested were in the 15-45 year age group. One-hundred-sixty (79%) patients had anaemia. MCV was lower than 76 fl in all the cases. Mean MCV was 59.1 fl. MCH was low, the mean MCH being 19.3 g/dl. MCH <26 gave sensitivity of 99% in detecting BTT. We calculated MI for these cases and found out that it was <12 in 75% of cases and <15 in 197 (97%). Conclusion: Beta-thalassaemia traits present with a microcytic hypochromic blood picture, detected on simple haematology analysers as low MCV and MCH and MI which provide a beta- thalassaemia trait.

  6. Increased Soluble Urokinase-Type Plasminogen Activator Receptor (suPAR Levels in Plasma of Suicide Attempters.

    Directory of Open Access Journals (Sweden)

    Filip Ventorp

    Full Text Available The soluble form of the urokinase receptor, suPAR, has been suggested as a novel biomarker of low-grade inflammation. Activation of the immune system has been proposed to contribute to the development of depression and suicidal behavior. In order to identify depressed and suicidal individuals who could benefit from an anti-inflammatory treatment, a reliable biomarker of low-grade inflammation is vital. This study evaluates plasma suPAR levels as a biomarker of low-grade inflammation in patients with major depressive disorder and in patients who recently attempted suicide. The plasma suPAR and an established biomarker, C reactive protein (CRP of suicide attempters (n = 54, depressed patients (n = 19 and healthy controls (n = 19 was analyzed with enzyme-linked immunosorbent assays. The biomarker attributes of sensitivity and sensibility were evaluated using ROC curve analysis. Both the depressed patients and suicide attempters had increased plasma suPAR. The levels of suPAR discriminated better between controls and suicide attempters than did CRP. In the future, plasma suPAR might be a superior prognosticator regarding outcome of treatment applying conventional antidepressants in conjunction with anti-inflammatory drugs.

    The co-occurrence of Autism Spectrum Disorder (ASD) and Borderline Personality Disorder (BPD) is not rare and has been linked to increased suicidality. Despite this significant comorbidity between ASD and BPD, no study had examined the co-occurrence of autistic traits and borderline personality disorder traits in the general population. The aim of the present study was to examine the co-occurrence of autistic and borderline traits in a non-clinical sample of young adults and its influence on the levels of suicidal ideation and depressive symptomatology. Participants were 474 college students who completed self-report questionnaires. Data were analysed using correlation and cluster analyses. Borderline personality traits and autistic traits were weakly correlated. However, cluster analysis yielded four groups: a low traits group, a borderline traits group, an autistic traits group, and a group characterized by high levels of both traits. Cluster analysis revealed that autistic and borderline traits can co-occur in a significant proportion of young adults. The high autistic and borderline traits group constituted 17% of the total sample and had higher level of suicidal ideation than the borderline traits group, despite similar levels of depressive symptoms. This result suggests that the higher suicidality observed in patients with comorbid ASD and BPD may extent to non-clinical individuals with high levels of co-occurrent autistic and borderline traits.

    Here, we present for the first time that Mycobacterium tuberculosis ParB is phosphorylated by several mycobacterial Ser/Thr protein kinases in vitro. ParB and ParA are the key components of bacterial chromosome segregation apparatus. ParB is a cytosolic conserved protein that binds specifically to centromere-like DNA parS sequences and interacts with ParA, a weak ATPase required for its proper localization. Mass spectrometry identified the presence of ten phosphate groups, thus indicating that ParB is phosphorylated on eight threonines, Thr32, Thr41, Thr53, Thr110, Thr195, and Thr254, Thr300, Thr303 as well as on two serines, Ser5 and Ser239. The phosphorylation sites were further substituted either by alanine to prevent phosphorylation or aspartate to mimic constitutive phosphorylation. Electrophoretic mobility shift assays revealed a drastic inhibition of DNA-binding by ParB phosphomimetic mutant compared to wild type. In addition, bacterial two-hybrid experiments showed a loss of ParA-ParB interaction with the phosphomimetic mutant, indicating that phosphorylation is regulating the recruitment of the partitioning complex. Moreover, fluorescence microscopy experiments performed in the surrogate Mycobacterium smegmatis ΔparB strain revealed that in contrast to wild type Mtb ParB, which formed subpolar foci similar to M. smegmatis ParB, phoshomimetic Mtb ParB was delocalized. Thus, our findings highlight a novel regulatory role of the different isoforms of ParB representing a molecular switch in localization and functioning of partitioning protein in Mycobacterium tuberculosis.

    In the past, several studies have suggested the existence of a "periarthritic personality" in patients with frozen shoulder. We conducted a study to determine differences in personality traits in patients with primary and secondary frozen shoulders. We prospectively evaluated 118 patients (84 women and 34 men; mean age, 53.8 years; SD 7.56) with a frozen shoulder. Of these patients, 48 had an idiopathic frozen shoulder and 70 had a secondary frozen shoulder. Personality traits were determined by the NEO Five-Factor Inventory (NEO-FFI) scale. This questionnaire measures the 5 major personality traits and is based on the norms determined in a neutral test situation for 2415 controls. Compared with healthy controls, no differences in personality traits were found in patients with primary and secondary frozen shoulder, except for Conscientiousness and Extraversion, for which patients with secondary frozen shoulder scored significantly higher than healthy controls. Patients with primary frozen shoulder scored significantly higher on Openness to Experience than did patients with secondary frozen shoulder; on the other 4 Big Five personality traits, no significant differences were found between patients with primary and secondary frozen shoulder. More specifically, patients with idiopathic frozen shoulder did not score higher on the trait Neuroticism as would be expected from previous publications. Our study results do not indicate that patients with an idiopathic frozen shoulder have a specific personality compared with healthy controls. Only a few differences were found in personality traits when the entire frozen shoulder group was compared with healthy controls and between patients with primary and secondary frozen shoulders. The results of this study suggest that these differences are not sufficient to speak about a specific "frozen shoulder personality."

    The 16th century by its passionate side has been the favourite one of authors of historical novels in which among the heroes of "cloak and dagger stories" appears sometime Ambroise Paré. Alexandre Dumas (the father) has shown him at the court of Charles IX in La Reine Margot (1845) where he does not however play a great role. On the contrary, Balzac in Le Martyr calviniste (1842) has given him a capital part close to the dying François II, whom he intended to trepanize but had to give up this idea as a consequence of the opposition of the queen-mother Catherine de Médicis. In the present century, Robert Merle in Paris ma bonne ville (Fortune de France, 3, 1980) shows Paré at the time of the Saint Barthélemy.

  13. Quantitative traits and diversification.

    FitzJohn, Richard G

    2010-12-01

    Quantitative traits have long been hypothesized to affect speciation and extinction rates. For example, smaller body size or increased specialization may be associated with increased rates of diversification. Here, I present a phylogenetic likelihood-based method (quantitative state speciation and extinction [QuaSSE]) that can be used to test such hypotheses using extant character distributions. This approach assumes that diversification follows a birth-death process where speciation and extinction rates may vary with one or more traits that evolve under a diffusion model. Speciation and extinction rates may be arbitrary functions of the character state, allowing much flexibility in testing models of trait-dependent diversification. I test the approach using simulated phylogenies and show that a known relationship between speciation and a quantitative character could be recovered in up to 80% of the cases on large trees (500 species). Consistent with other approaches, detecting shifts in diversification due to differences in extinction rates was harder than when due to differences in speciation rates. Finally, I demonstrate the application of QuaSSE to investigate the correlation between body size and diversification in primates, concluding that clade-specific differences in diversification may be more important than size-dependent diversification in shaping the patterns of diversity within this group.

    A set of 22 experimental wheat lines along with four check cultivars were evaluated in in-irrigated and unirrgated environments with objectives to determine genetic and phenotypic variation and heritability estimates for yield and its traits- The two environments were statistically at par for physiological maturity, plant height, spikes m/sub -2/. spike lets spike/sup -1/ and 1000-grain weight. Highly significant genetic variability existed among wheat lines (P < 0.0 I) in the combined analysis across two test environments for traits except 1000- grain weight. Genotypes x environment interactions were non-significant for traits indicating consistent performance of lines in two test environments. However lines and check cultivars were two to five days early in maturity under unirrigated environment. Plant height, spikes m/sup -2/ and 1000-grain weight also reduced under unirrigated environments. Genetic variances were greater than Environmental variances for most of traits- Heritability estimates were of higher magnitude (0.74 to 0.96) for plant height, medium (0.31 to 0.56) for physiological maturity. spikelets spike/sup -1/ (unirrigated) and 1000-grain weight, and low for spikes m/sup -2/.

    Isthmic spondylolysis can significantly decrease functional abilities, especially in adolescent athletes. Although treatment can range from observation to surgery, direct screw placement through the fractured pars, or Buck's procedure, may be a more minimally invasive procedure than the more common pedicle screw-hook construct. Review of surgical databases identified 16 consecutive patients treated with Buck's procedure from 2004 to 2010. Twelve patients were treated at Miami Children's Hospital and 4 at Barrow Neurological Institute. Demographics and clinical and radiographic outcomes were recorded and analyzed retrospectively. The 16 patients had a median age of 16 years, and 14 were 20 years or younger at the time of treatment. Symptoms included axial back pain in 100% of patients with concomitant radiculopathy in 38%. Pars defects were bilateral in 81% and unilateral in 19% for a total of 29 pars defects treated using Buck's procedure. Autograft or allograft augmented with recombinant human bone morphogenetic protein as well as postoperative bracing was used in all cases. Postoperatively, symptoms resolved completely or partially in 15 patients (94%). Of 29 pars defects, healing was observed in 26 (89.6%) prior to 1 revision surgery, and an overall fusion rate of 97% was observed at last radiological follow-up. There were no implant failures. All 8 athletes in this group had returned to play at last follow-up. Direct screw repair of the pars interarticularis defect as described in this series may provide a more minimally invasive treatment of adolescent patients with satisfactory clinical and radiological outcomes, including return to play of adolescent athletes.

    This study investigated if the linkages between trait emotional intelligence (trait EI) and the Five-Factor Model of personality were invariant between men and women. Five English-speaking samples (N = 307-685) of mostly undergraduate students each completed a different measure of the Big Five personality traits and either the full form or short form of the Trait Emotional Intelligence Questionnaire (TEIQue). Across samples, models predicting global TEIQue scores from the Big Five were invariant between genders, with Neuroticism and Extraversion being the strongest trait EI correlates, followed by Conscientiousness, Agreeableness, and Openness. However, there was some evidence indicating that the gender-specific contributions of the Big Five to trait EI vary depending on the personality measure used, being more consistent for women. Discussion focuses on the validity of the TEIQue as a measure of trait EI and its psychometric properties, more generally. PMID:25866439

    Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker that is increasingly used for evaluation of systemic inflammation. This study was performed to investigate whether suPAR may possess a diagnostic value in patients with ventilator-associated pneumonia (VAP). This clinical study was performed in the anesthesia intensive care units (ICUs) of our university. In addition to descriptive data, WBC, serum levels of C-reactive protein (CRP) and suPAR prior to and after development of VAP were noted and compared in 31 patients (22 men, 9 women) diagnosed with VAP (Study Group) and 19 patients without VAP (Control Group) in ICU (14 men, 5 women). The suPAR (P = 0.023), CRP (P = 0.037), WBCs (P = 0.024) in patients with VAP were significantly higher than patients without VAP. There was no remarkable difference in terms of WBCs (P = 0.052) and suPAR levels (P = 0.616) between groups on the first day of connection to mechanical ventilator. The suPAR and CRP levels in patients with VAP were significantly higher than prior to development of VAP (P = 0.001 for both). Area under curve value after diagnosis of pneumonia was found 0.248 (P = 0.002). To conclude, our results suggest that suPAR can be a useful diagnostic biomarker in patients with VAP. However, clinical trials on larger series are warranted to explore the clinical significance more accurately. © 2016 John Wiley & Sons Ltd.

    The par2 locus of Escherichia coli plasmid pB171 encodes two trans-acting proteins, ParA and ParB, and two cis-acting sites, parC1 and parC2, to which ParB binds cooperatively. ParA is related to MinD and oscillates in helical structures and thereby positions ParB/parC-carrying plasmids regularly......, hence identifying the N terminus of ParB as a requirement for ParB-mediated centromere pairing. These observations suggest that centromere pairing is an important intermediate step in plasmid partitioning mediated by the common type I loci....

    The objective is to assess the safety, tolerability, and efficacy of sacubitril/valsartan compared with enalapril in patients with heart failure (HF) with a reduced ejection fraction (EF) stabilized during hospitalization for acute decompensated HF. Sacubitril/valsartan, a first-in-class angiotensin receptor-neprilysin inhibitor, improves survival among ambulatory HF patients with a reduced EF. However, there is very limited experience with the in-hospital initiation of sacubitril/valsartan in patients who have been stabilized following hospitalization for acute decompensated HF. PIONEER-HF is a 12-week, prospective, multicenter, double-blind, randomized controlled trial enrolling a planned 882 patients at more than 100 participating sites in the United States. Medically stable patients >18 years of age with an EF 1600 pg/mL or b-type natriuretic peptide >400 pg/mL are eligible for participation no earlier than 24 hours and up to 10 days from initial presentation while still hospitalized. Patients are randomly assigned 1:1 to in-hospital initiation of sacubitril/valsartan titrated to 97/103 mg by mouth twice daily versus enalapril titrated to 10 mg by mouth twice daily for 8 weeks. All patients receive open-label treatment with sacubitril/valsartan for the remaining 4 weeks of the study. The primary efficacy end point is the time-averaged proportional change in amino terminal-pro b-type natriuretic peptide from baseline through weeks 4 and 8. Secondary and exploratory end points include serum and urinary biomarkers as well as clinical outcomes. Safety end points include the incidence of angioedema, hypotension, renal insufficiency, and hyperkalemia. The PIONEER-HF trial will inform clinical practice by providing evidence on the safety, tolerability, and efficacy of in-hospital initiation of sacubitril/valsartan among patients who have been stabilized following an admission for acute decompensated HF with a reduced EF.

  6. Galectin-3 facilitates cell motility in gastric cancer by up-regulating protease-activated receptor-1 (PAR-1 and matrix metalloproteinase-1 (MMP-1.

    Directory of Open Access Journals (Sweden)

    Seok-Jun Kim

    Full Text Available BACKGROUND: Galectin-3 is known to regulate cancer metastasis. However, the underlying mechanism has not been defined. Through the DNA microarray studies after galectin-3 silencing, we demonstrated here that galectin-3 plays a key role in up-regulating the expressions of protease-activated receptor-1 (PAR-1 and matrix metalloproteinase-1 (MMP-1 PAR-1 thereby promoting gastric cancer metastasis. METHODOLOGY/PRINCIPAL FINDINGS: We examined the expression levels of Galectin-3, PAR-1, and MMP-1 in gastric cancer patient tissues and also the effects of silencing these proteins with specific siRNAs and of over-expressing them using specific lenti-viral constructs. We also employed zebrafish embryo model for analysis of in vivo gastric cancer cell invasion. These studies demonstrated that: a galectin-3 silencing decreases the expression of PAR-1. b galectin-3 over-expression increases cell migration and invasion and this increase can be reversed by PAR-1 silencing, indicating that galectin-3 increases cell migration and invasion via PAR-1 up-regulation. c galectin-3 directly interacts with AP-1 transcriptional factor, and this complex binds to PAR-1 promoter and drives PAR-1 transcription. d galectin-3 also amplifies phospho-paxillin, a PAR-1 downstream target, by increasing MMP-1 expression. MMP-1 silencing blocks phospho-paxillin amplification and cell invasion caused by galectin-3 over-expression. e Silencing of either galectin-3, PAR-1 or MMP-1 significantly reduced cell migration into the vessels in zebrafish embryo model. f Galectin-3, PAR-1, and MMP-1 are highly expressed and co-localized in malignant tissues from gastric cancer patients. CONCLUSIONS/SIGNIFICANCE: Galectin-3 plays the key role of activating cell surface receptor through production of protease and boosts gastric cancer metastasis. Galectin-3 has the potential to serve as a useful pharmacological target for prevention of gastric cancer metastasis.

    Full Text Available The people with Borderline Personality Disorder (BPD show pathological personality traits in three of the five domains (APA 2013. In addition to diagnostic criteria for BPD, described by Diagnostic and Statistical Manual of Mental Disorders (DSM-5, the dimensional model of personality disorder, based on five-factor model of personality, seems to gain interest as it promisses to eliminate problems associated with poor-fit, co-morbidity and unclear diagnosis. The purpose of this study is to identify the personality traits by people who are already diagnosed with BPD using the DSM-5 categorical criteria. Based on the theoretical concepts and existing research findings as well as increased interest in the dimensional personality theory, we assume that people diagnosed with BPD will show high levels of pathology on three trait domains: negative affectivity, disinhibition and antagonism. This study was conducted in Germany in psychiatric clinic. Fifteen participants represented a convenience sample, of patients already diagnosed with BPD. For this study Personality Inventory for DSM-5 (PID-5 was used. The findings supported the assumptions that people with BPD show some degree of anxiousness, emotional lability, hostility, impulsivity, risk taking and separation anxiety. The study also found that traits such as distractibility, withdrawal and submissiveness were also present in this participant group. Even though, study was conducted with small number of participants it has provided contribution to the already existing knowledge and understanding in regards to common personality treats for people diagnosed with BPD.

    Barber and Muenz (1996) reported that cognitive behavior therapy (CBT) was more effective than interpersonal therapy (IPT) for depressed patients with elevated levels of avoidant personality disorder, while IPT was more effective than CBT in patients with elevated levels of obsessive-compulsive personality disorder. These findings may have important clinical implications, but have not yet been replicated. We conducted a study using data from a randomized clinical trial comparing the efficacy of CBT and short-term psychodynamic supportive psychotherapy in the outpatient treatment of depression. We found no evidence indicating that avoidant patients may benefit more from CBT compared to short-term psychodynamic supportive therapy (SPSP). Our results indicate that treatment effect does not depend on the level of avoidance, or obsessive-compulsiveness personality disorders further examine the influence of personality disorders on the effectiveness of CBT or psychodynamic therapy in the treatment of depression.

    This study investigated the occurrence of Strongyloides stercoralis infestation and coinfection with HTLV-1/2 in Belém, Brazil. S. stercoralis was investigated in stool samples obtained from individuals infected with HTLV-1/2 and their uninfected relatives. The frequency of S. stercoralis was 9% (9/100), including six patients infected with HTLV-1 (14.3%), two patients infected with HTLV-2 (11.1%), and one uninfected relative. Two cases of hyperinfestation by S. stercoralis were characterized as HTLV-1. These results support the need for the routine investigation of S. stercoralis in patients with HTLV-1, in an attempt to prevent the development of severe forms of strongyloidiasis.

    In order to evidence myocardial ischemia-leading to ventricular dysfunction-during weaning from mechanical ventilation in patients with chronic obstructive pulmonary disease, thallium myocardial tomography and gated blood pool studies were performed in 9 patients during mechanical ventilation and during weaning from mechanical ventilation. During the latter, results of gated blood pool studies showed a diffuse homogeneous left ventricular dysfunction. A fixed lower thallium uptake in the septum than in the lateral wall was found with the quantitative analysis of myocardial tomograms. Partial volume effect is likely the cause of this septal defect. The hypothesis of a diffuse ischemia cannot be excluded; but, without the absolute quantification of tomographic data, it cannot be proven.

    Short stature homeobox-containing gene, MIM 312865 (SHOX) is located within the pseudoautosomal region 1 (PAR1) of the sex chromosomes. Mutations in SHOX or its downstream transcriptional regulatory elements represent the underlying molecular defect in ~60% of Léri-Weill dyschondrosteosis (LWD) and ~5-15% of idiopathic short stature (ISS) patients. Recently, three novel enhancer elements have been identified upstream of SHOX but to date, no PAR1 deletions upstream of SHOX have been observed that only encompass these enhancers in LWD or ISS patients. We set out to search for genetic alterations of the upstream SHOX regulatory elements in 63 LWD and 100 ISS patients with no known alteration in SHOX or the downstream enhancer regions using a specifically designed MLPA assay, which covers the PAR1 upstream of SHOX. An upstream SHOX deletion was identified in an ISS proband and her affected father. The deletion was confirmed and delimited by array-CGH, to extend ~286 kb. The deletion included two of the upstream SHOX enhancers without affecting SHOX. The 13.3-year-old proband had proportionate short stature with normal GH and IGF-I levels. In conclusion, we have identified the first PAR1 deletion encompassing only the upstream SHOX transcription regulatory elements in a family with ISS. The loss of these elements may result in SHOX haploinsufficiency because of decreased SHOX transcription. Therefore, this upstream region should be included in the routine analysis of PAR1 in patients with LWD, LMD and ISS.

    The author report a study aimed at assessing the tolerance and efficiency of a technique which has been used for some years and which comprises the implantation of Gliadel wafers in the operative bed before performing a concomitant radiotherapy and chemotherapy with temozolomide, followed by six adjuvant chemotherapy sessions with the Stupp protocol. Four women and seven men have been implanted with Gliadel wafers. Only one patient did not have the concomitant chemo-radiotherapy. The global survival and global survival without progression have been assessed. Even though the obtained results are encouraging, the concomitant chemo-radiotherapy had to be stopped for three patients due to haematological consequences. Short communication

    Brown adipose tissue (BAT) provides a means of nonshivering thermogenesis. In humans, active BAT can be visualized by 18 F-FDG uptake as detected by PET combined with CT. The retrospective analysis of clinical scans is a valuable source to identify anthropometric parameters that influence BAT mass and activity and thus the potential efficacy of envisioned drugs targeting this tissue to treat metabolic disease. Methods: We analyzed 2,854 18 F-FDG PET/CT scans from 1,644 patients and identified 98 scans from 81 patients with active BAT. We quantified the volume of active BAT depots (mean values in mL ± SD: total BAT, 162 ± 183 [ n = 98]; cervical, 40 ± 37 [ n = 53]; supraclavicular, 66 ± 68 [ n = 71]; paravertebral, 51 ± 53 [ n = 69]; mediastinal, 43 ± 40 [ n = 51]; subphrenic, 21 ± 21 [ n = 29]). Because only active BAT is detectable by 18 F-FDG uptake, these numbers underestimate the total amount of BAT. Considering only 32 scans of the highest activity as categorized by a visual scoring strategy, we determined a mean total BAT volume of 308 ± 208 mL. In 30 BAT-positive patients with 3 or more repeated scans, we calculated a much higher mean probability to redetect active BAT (52% ± 25%) as compared with the overall prevalence of 4.9%. We calculated a BAT activity index (BFI) based on volume and intensity of individual BAT depots. Results: We detected higher total BFI in younger patients ( P = 0.009), whereas sex, body mass index, height, mass, outdoor temperature, and blood parameters did not affect total or depot-specific BAT activity. Surprisingly, renal creatinine clearance as estimated from mass, age, and plasma creatinine was a significant predictor of BFI on the total ( P = 0.005) as well as on the level of several individual depots. In summary, we detected a high amount of more than 300 mL of BAT tissue. Conclusion: BAT-positive patients represent a group with a higher than usual probability to activate BAT during a scan. Estimated renal creatinine

    The objective was to retrospectively record the CT and MRI features and healing patterns of acute, incomplete stress fractures of the pars interarticularis. The CT scans of 156 adolescents referred with suspected pars interarticularis stress fractures were reviewed. Patients with incomplete (grade 2) pars fractures were included in the study. Fractures were assessed on CT according to vertebral level, location of cortical involvement and direction of fracture propagation. MRI was also performed in 72 of the 156 cases. MRI images of incomplete fractures were assessed for the presence of marrow oedema and cortical integrity. Fracture healing patterns were characterised on follow-up CT imaging. Twenty-five incomplete fractures were identified in 23 patients on CT. All fractures involved the inferior or infero-medial cortex of the pars and propagated superiorly or superolaterally. Ninety-two percent of incomplete fractures demonstrated either complete or partial healing on follow-up imaging. Two (8%) cases progressed to complete fractures. Thirteen incomplete fractures in 11 patients confirmed on CT also had MRI, and 92% demonstrated oedema in the pars. Ten out of thirteen fractures (77%) showed a break in the infero-medial cortex with intact supero-lateral cortex, which correlated with the CT findings. MRI incorrectly graded one case as a complete (grade 3) fracture, and 2 cases as (grade 1) stress reaction. Six fractures had follow-up MRI, 67% showed partial or complete cortical healing, and the same number showed persistent marrow oedema. Incomplete fracture of the pars interarticularis represents a stage of the evolution of a complete stress fracture. The direction of fracture propagation is consistent, and complete healing can be achieved in most cases with appropriate clinical management. CT best demonstrates fracture size and extent, and is the most appropriate modality for follow-up. MRI is limited in its ability to fully depict the cortical integrity of

    realización de exámenes y procedimientos quirúrgicos para la corrección de deformidades bajo anestesia o sedación es común en esos pacientes. Cada vez más se hace necesaria la monitorización del estado de hipnosis del paciente anestesiado y podemos incluir en ese grupo los pacientes con parálisis cerebral. El objetivo de este estudio fue evaluar la eficiencia del EEG-BIS en los pacientes con parálisis cerebral (PC en comparación con los pacientes sin enfermedades neurológicas (sin PC, en estado de vigilia. MÉTODO: Fueron evaluados 2 grupos de pacientes: uno con diagnóstico de parálisis cerebral y otro sin enfermedad del sistema nervioso central (SNC. A la víspera de la intervención, en la enfermería, con los pacientes despiertos era colocado el monitor de EEG-BIS y solicitado que cerrasen los ojos. Los valores que aparecían en la pantalla del monitor, en un intervalo de 10 minutos, eran anotados y registrados en ficha estandarizada, siendo calculado un valor promedio por paciente. RESULTADOS: Fueron evaluados 188 pacientes, de ambos sexos, con edad promedio de 10, 07 ± 2,9 (PC y 10,21 ± 3,1 (sin PC años. El grupo PC presentó EEG-BIS basal de 95,83 ± 5,142 y el grupo sin PC de 96,56 ± 1,941 sin haber una diferencia estadística significativa entre ellos. CONCLUSIONES: Las señales de EEG se captan normalmente y los valores de EEG-BIS de los pacientes con PC son semejantes a los de los s pacientes sin PC en estado de vigilia.BACKGROUND AND OBJECTIVES: The EEG-BIS was created after studies in healthy adult subjects, and studies in children were first published in 1998. Cerebral palsy (CP is secondary to a static lesion of the developing brain. The need to perform exams and surgical procedures to correct deformities, under anesthesia or sedation, is common in these patients. The need for monitoring of the hypnotic state in anesthetized patients has increased; patients with cerebral palsy can be included in this group of patients. The objective of this

    Full Text Available Hepatitis C virus (HCV and human T-cell lymphotropic virus type 1 (HTLV-1 share routes of transmission and some individuals have dual infection. Although some studies point to a worse prognosis of hepatitis C virus in patients co-infected with HTLV-1, the interaction between these two infections is poorly understood. This study evaluated the influence of HTLV-1 infection on laboratory parameters in chronic HCV patients. Twelve HTLV-1/HCV-coinfected patients were compared to 23 patients infected only with HCV, in regard to demographic data, risk factors for viral acquisition, HCV genotype, presence of cirrhosis, T CD4+ and CD8+ cell counts and liver function tests. There was no difference in regard to age, gender, alcohol consumption, smoking habits, HCV genotype or presence of cirrhosis between the groups. Intravenous drug use was the most common risk factor among individuals co-infected with HTLV-1. These patients showed higher TCD8+ counts (p = 0.0159 and significantly lower median values of AST and ALT (p = 0.0437 and 0.0159, respectively. In conclusion, we have shown that HCV/HTLV-1 co-infected patients differs in laboratorial parameters involving both liver and immunological patterns. The meaning of these interactions in the natural history of these infections is a matter that deserves further studies.O vírus da hepatite C (VHC e vírus linfotrópico humano tipo 1 (HTLV-1 compartilham formas de transmissão e algumas pessoas apresentam coinfecção.

    Since its introduction in clinical practice in the 1990 s, positron emission tomography (PET), usually with {sup 18}F-fluoro-2-deoxy-D-glucose ({sup 18}F-F.D.G.), has become an important imaging modality in patients with cancer. For cervix carcinoma, F.D.G.-PET is significantly more accurate than computed tomography (CT) and is recommended for loco-regional lymph node and extra pelvic staging. The metabolic dimension of the technique provides additional prognostic information. Ongoing studies now concentrate on more advanced clinical applications, such as the planning of radiotherapy, the response evaluation after the induction of therapy, the early detection of recurrence. Technical innovations, such as PET cameras with better spatial resolution and hybrid positron emission tomography/computed tomography (PET-CT), available now on the whole territory, provide both anatomic and metabolic information in the same procedure. From the point of view of biological metabolism, new radiopharmaceutical probes are being developed. Those hold promise for future refinements in this field. This article reviews the current applications of F.D.G.-PET in patients with cervix cancer. (authors)

    The urokinase plasminogen activator receptor is highly expressed and its gene is amplified in about 50% of pancreatic ductal adenocarcinomas; this last feature is associated with worse prognosis. It is unknown whether the level of its soluble form (suPAR) in urine may be a diagnostic-prognostic marker in these patients. The urinary level of suPAR was measured in 146 patients, 94 pancreatic ductal adenocarcinoma and 52 chronic pancreatitis. Urine from 104 healthy subjects with similar age and gender distribution served as controls. suPAR levels were normalized with creatinine levels (suPAR/creatinine, ng/mg) to remove urine dilution effect. Urinary suPAR/creatinine values of pancreatic ductal adenocarcinoma patients were significantly higher (median 9.8; 25 th -75 th percentiles 5.3-20.7) than those of either healthy donors (median 0; 0-0.5) or chronic pancreatitis patients (median 2.7; 0.9-4.7). The distribution of values among cancer patients was widespread and asymmetric, 53% subjects having values beyond the 95 th percentile of healthy donors. The values of suPAR/creatinine did not correlate with tumour stage, Ca19-9 or CEA levels. Higher values correlated with poor prognosis among non-resected patients at univariate analysis; multivariate Cox regression identified high urinary suPAR/creatinine as an independent predictor of poor survival among all cancer patients (odds ratio 2.10, p = 0.0023), together with tumour stage (stage III odds ratio 2.65, p = 0.0017; stage IV odds ratio 4.61, p < 0.0001) and female gender (odds ratio 1.85, p = 0.01). A high urinary suPAR/creatinine ratio represents a useful marker for the identification of a subset of patients with poorer outcome

    Full Text Available Abstract A whole genome scan was carried out to detect quantitative trait loci (QTL for fertility traits in Finnish Ayrshire cattle. The mapping population consisted of 12 bulls and 493 sons. Estimated breeding values for days open, fertility treatments, maternal calf mortality and paternal non-return rate were used as phenotypic data. In a granddaughter design, 171 markers were typed on all 29 bovine autosomes. Associations between markers and traits were analysed by multiple marker regression. Multi-trait analyses were carried out with a variance component based approach for the chromosomes and trait combinations, which were observed significant in the regression method. Twenty-two chromosome-wise significant QTL were detected. Several of the detected QTL areas were overlapping with milk production QTL previously identified in the same population. Multi-trait QTL analyses were carried out to test if these effects were due to a pleiotropic QTL affecting fertility and milk yield traits or to linked QTL causing the effects. This distinction could only be made with confidence on BTA1 where a QTL affecting milk yield is linked to a pleiotropic QTL affecting days open and fertility treatments.

The postoperative UBM image of the sclerotomy site at 8 weeks demonstrated a clear wound without any vitreous adhesion or incarceration. Intraoperative hyphema was seen in 1 (2.8% case and postoperative uveitis was seen in 2 (5.7% cases, which resolved with medications. No case of an iatrogenic retinal break or retinal detachment was reported. Conclusions: PPAV enables a closed chamber approach, allows thorough cleanup of vitreous in the pupillary plane and anterior chamber and affords better access to the subincisional and retropupillary cortical remnant with a significant visual outcome and an acceptable complication rate.

    While an interactive effect of genes with adverse life events is increasingly appreciated in current concepts of depression etiology, no data are presently available on interactions between genetic and environmental (G x E) factors with respect to personality and related disorders. The present study therefore aimed to detect main effects as well as interactions of serotonergic candidate genes (coding for the serotonin transporter, 5-HTT; the serotonin autoreceptor, HTR1A; and the enzyme which synthesizes serotonin in the brain, TPH2) with the burden of life events (#LE) in two independent samples consisting of 183 patients suffering from personality disorders and 123 patients suffering from adult attention deficit/hyperactivity disorder (aADHD). Simple analyses ignoring possible G x E interactions revealed no evidence for associations of either #LE or of the considered polymorphisms in 5-HTT and TPH2. Only the G allele of HTR1A rs6295 seemed to increase the risk of emotional-dramatic cluster B personality disorders (p = 0.019, in the personality disorder sample) and to decrease the risk of anxious-fearful cluster C personality disorders (p = 0.016, in the aADHD sample). We extended the initial simple model by taking a G x E interaction term into account, since this approach may better fit the data indicating that the effect of a gene is modified by stressful life events or, vice versa, that stressful life events only have an effect in the presence of a susceptibility genotype. By doing so, we observed nominal evidence for G x E effects as well as main effects of 5-HTT-LPR and the TPH2 SNP rs4570625 on the occurrence of personality disorders. Further replication studies, however, are necessary to validate the apparent complexity of G x E interactions in disorders of human personality.

    Protease-activated receptor-1 (PAR1) is the prototypic member of a family of four G-protein-coupled receptors that signal in response to extracellular proteases. In the peripheral nervous system, the expression and/or the role of PARs are still poorly investigated. High PAR1 mRNA expression was found in the rat dorsal root ganglia and the signal intensity of PAR1 mRNA increased in response to sciatic nerve transection. In the sciatic nerve, functional PAR1 receptor was reported at the level of non-compacted Schwann cell myelin microvilli of the nodes of Ranvier. Schwann cells are the principal population of glial cells of the peripheral nervous system which myelinate axons playing an important role during axonal regeneration and remyelination. The present study was undertaken in order to determine if the activation of PAR1 affects the neurotrophic properties of Schwann cells. Our results suggest that the stimulation of PAR1 could potentiate the Schwann cell ability to favour nerve regeneration. In fact, the conditioned medium obtained from Schwann cell cultures challenged with a specific PAR1 activating peptide (PAR1 AP) displays increased neuroprotective and neurotrophic properties with respect to the culture medium from untreated Schwann cells. The proteomic analysis of secreted proteins in untreated and PAR1 AP-treated Schwann cells allowed the identification of factors differentially expressed in the two samples. Some of them (such as macrophage migration inhibitory factor, matrix metalloproteinase-2, decorin, syndecan 4, complement C1r subcomponent, angiogenic factor with G patch and FHA domains 1) appear to be transcriptionally regulated after PAR1 AP treatment as shown by RT-PCR.

    Analysis of associations between initial neurotic personality traits and subsequent reduction of suicidal ideation (SI) - or lack of such reduction - obtained until the end of hospitalization in patients who underwent the course of intensive psychotherapy conducted in integrative approach with predominance of psychodynamic approach. Symptom Checklist KO"O", Neurotic Personality Questionnaire KON-2006 and Life Inventory completed by 461 women and 219 men hospitalized in the day-hospital due to neurotic, behavioral and personality disorders between 2005-2013. At the stage of qualification 134 women and 80 men reported SI, of whom subsequently 84.3% and 77.5% respectively improved. Women with prominent Tendency to risk-taking (p=0.002) and Impulsiveness (p=0.038) constituted subgroups with decreased chances of improvement in terms of SI, while men with prominently elevated level of Envy (p=0.041) and women who seemed to have difficulties in expressing anger adequately (ppsychotherapy. Thus, those subgroups require special attention and diligent selection of therapeutic methods. Also, it is probable that focusing therapy at the above-mentioned personality components may increase effectiveness of SI treatment. Reducing SI during psychotherapy appears to be highly effective especially in women with difficulties in expressing anger adequately and in men with prominently elevated level of Envy, which suggests adequacy of this treatment choice and of targeting those difficulties during psychotherapy.

    The film Taare Zameen Par (Stars upon the Ground) portrays the tormented life at school and at home of a child with dyslexia and his eventual success after his artistic talents are discovered by his art teacher at the boarding school. The film hints at a curious neurocognitive phenomenon of creativity in the midst of language disability, as exemplified in the lives of people like Leonardo da Vinci and Albert Einstein, both of whom demonstrated extraordinary creativity even though they were probably affected with developmental learning disorders. It has been hypothesized that a developmental delay in the dominant hemisphere most likely 'disinhibits' the nondominant parietal lobe, unmasking talents-artistic or otherwise-in some such individuals. It has been suggested that, in remedial training, children with learning disorders be encouraged to develop such hidden talents to full capacity, rather than be subjected to the usual overemphasis on the correction of the disturbed coded symbol operations.

    We examined changes in avoidant and dependent personality disorder dimensions, and pre-treatment and in-treatment factors associated with such changes in 77 patients, randomized to medication-free residential cognitive (CT) or residential interpersonal therapy for social phobia. Personality disorders and personality dimensions according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were assessed at pre-treatment and at one-year post-treatment. Both treatments were associated with a decrease in avoidant and dependent personality dimensions; dependent dimension decreased more in CT. Changes in cognitive factors predicted changes in both personality dimensions, whereas changes in symptoms or interpersonal factors did not. Change in the cognitive factor estimated cost was the most powerful predictor in the avoidant dimension, as it was the only predictor that remained significant in the forward regression analyses. Change in the cognitive factor estimated cost, and treatment were the most powerful predictors of change in the dependent dimension. Pre-treatment use of anxiolytics predicted larger changes in both PD dimensions.

  18. ParABS system in chromosome partitioning in the bacterium Myxococcus xanthus.

    Directory of Open Access Journals (Sweden)

    Antonio A Iniesta

    Full Text Available Chromosome segregation is an essential cellular function in eukaryotic and prokaryotic cells. The ParABS system is a fundamental player for a mitosis-like process in chromosome partitioning in many bacterial species. This work shows that the social bacterium Myxococcus xanthus also uses the ParABS system for chromosome segregation. Its large prokaryotic genome of 9.1 Mb contains 22 parS sequences near the origin of replication, and it is shown here that M. xanthus ParB binds preferentially to a consensus parS sequence in vitro. ParB and ParA are essential for cell viability in M. xanthus as in Caulobacter crescentus, but unlike in many other bacteria. Absence of ParB results in anucleate cells, chromosome segregation defects and loss of viability. Analysis of ParA subcellular localization shows that it clusters at the poles in all cells, and in some, in the DNA-free cell division plane between two chromosomal DNA masses. This ParA localization pattern depends on ParB but not on FtsZ. ParB inhibits the nonspecific interaction of ParA with DNA, and ParA colocalizes with chromosomal DNA only when ParB is depleted. The subcellular localization of ParB suggests a single ParB-parS complex localized at the edge of the nucleoid, next to a polar ParA cluster, with a second ParB-parS complex migrating after the replication of parS takes place to the opposite nucleoid edge, next to the other polar ParA cluster.

    Using in vitro TIRF- and electron-microscopy, we reinvestigated the dynamics of native ParM, a prokaryotic DNA segregation protein and actin homolog. In contrast to a previous study, which used a cysteine ParM mutant, we find that the polymerization process of wild type ATP-ParM filaments consists of a polymerization phase and a subsequent steady state phase, which is dynamically unstable, like that of microtubules. We find that the apparent bidirectional polymerization of ParM, is not due to the intrinsic nature of this filament, but results from ParM forming randomly oriented bundles in the presence of crowding agents. Our results imply, that in the bacterium, ParM filaments spontaneously form bipolar bundles. Due to their intrinsic dynamic instability, ParM bundles can efficiently 'search' the cytoplasmic lumen for DNA, bind it equally well at the bipolar ends and segregate it approximately symmetrically, by the insertion of ParM subunits at either end

    The current research assesses relationships among coping skills, trait sport confidence, and trait anxiety. Two samples (n=47 and n=77) of international competitors from surf life saving (M=23.7 yr.) and touch rugby (M=26.2 yr.) completed the Athletic Coping Skills Inventory, Trait Sport Confidence Inventory, and Sport Anxiety Scale. Analysis yielded significant correlations amongst trait anxiety, sport confidence, and coping. Specifically confidence scores were positively associated with coping with adversity scores and anxiety scores were negatively associated. These findings support the inclusion of the personality characteristics of confidence and anxiety within the coping model presented by Hardy, Jones, and Gould, Researchers should be aware that confidence and anxiety may influence the coping processes of athletes.

  4. Tailoring mind-body therapies to individual needs: patients' program preference and psychological traits as moderators of the effects of mindfulness-based cancer recovery and supportive-expressive therapy in distressed breast cancer survivors.

    Mindfulness-based cancer recovery (MBCR) and supportive-expressive therapy (SET) are well-validated psycho-oncological interventions, and we have previously reported health benefits of both programs. However, little is known about patients' characteristics or program preferences that may influence outcomes. Therefore, this study examined moderators of the effects of MBCR and SET on psychological well-being among breast cancer survivors. A multi-site randomized controlled trial was conducted between 2007 and 2012 in two Canadian cities (Calgary and Vancouver). A total of 271 distressed stage I-III breast cancer survivors were randomized into MBCR, SET or a 1-day stress management seminar (SMS). Baseline measures of moderator variables included program preference, personality traits, emotional suppression, and repressive coping. Outcome measures of mood, stress symptoms, quality of life, spiritual well-being, post-traumatic growth, social support, and salivary cortisol were measured pre- and post intervention. Hierarchical regression analyses were used to assess moderator effects on outcomes. The most preferred program was MBCR (55%). Those who were randomized to their preference improved more over time on quality of life and spiritual well-being post-intervention regardless of the actual intervention type received. Women with greater psychological morbidity at baseline showed greater improvement in stress symptoms and quality of life if they received their preferred versus nonpreferred program. Patients' program preference and baseline psychological functioning, rather than personality, were predictive of program benefits. These results suggest incorporating program preference can maximize the efficacy of integrative oncology interventions, and emphasize the methodological importance of assessing and accommodating for preferences when conducting mind-body clinical trials. © The Author 2014.

    In this research, we sought to determine the association between beta-thalassemia trait and ischemic cerebrovascular accident (CVA). In acase-control study, 148 patients with thromboembolic cerebrovascular events were evaluated for the presence of hypertension, diabetes mellitus, hyperlipidemia, and beta-thalassemia trait. A total of 156 age- and sex-matched patients with no cardiac or cerebrovascular diseases, serving as the control group, were also investigated for the above-mentioned risk factors. We found that 6.1% of patients with ischemic CVA and 12.2% of the control group had beta-thalassemia trait (P = .066). In male patients, the negative association between ischemic CVA and presence of beta-thalassemia trait was significant (P = .008). In patients, the prevalence of hypertension was also significantly different between those with and without beta-thalassemia trait (P = .01); those with beta-thalassemia trait had a lower mean blood pressure than those without the trait. beta-Thalassemia trait may have a protective effect against ischemic CVA that might be caused by the lower arterial blood pressure observed in those with this trait.

    Prader-Willi syndrome (PWS) is a neuro-genetic disorder caused by the absence/loss of expression of one or more paternally expressed genes on chromosome 15 (q11-13). In this study, a comparative analysis of intelligence level and autistic traits was conducted between children with PWS (n = 30; 18 males, 12 females; age = 10.6 ± 2.8 years) and those with Asperger disorder (AD; n = 31; 24 males, 7 females; age = 10.5 ± 3.1 years). The children were compared by age group: lower elementary school age (6-8 years), upper elementary school age (9-12 years), and middle school age (13-15 years). As results, the intelligence levels of children with PWS were significantly lower than those with AD across all age groups. Autistic traits, assessed using the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS), revealed that among elementary school age children, those with PWS had less prominent autistic traits than those with AD, however, among middle school age children, those with PWS and AD showed similar prominence. An analysis of the PARS subscale scores by age group showed that while the profiles of autistic traits for children with PWS differed from those of children with AD at elementary school age, the profiles showed no significant differences between the groups at middle school age. The findings suggest that autistic traits in PWS become gradually more prominent with increasing of age and that these autistic traits differ in their fundamental nature from those observed in AD. © 2014 Wiley Periodicals, Inc.

    Full Text Available PURPOSE: To evaluate the changes in corneal topography after 20-gauge pars plana vitrectomy associated with scleral buckling for the repair of rhegmatogenous retinal detachment. METHODS: Twenty-five eyes of 25 patients with rhegmatogenous retinal detachment were included in this study. 20-gauge pars plana vitrectomy associated with scleral buckling was performed in all patients. The corneal topography of each was measured before surgery and one week, one month, and three months after surgery by computer-assisted videokeratoscopy. RESULTS: A statistically significant central corneal steepening (average, 0,9 D , p<0,001 was noted one week after surgery. The total corneal astigmatism had a significant increase in the first postoperative month (p=0,007. All these topographic changes persisted for the first month but returned to preoperative values three months after the surgery. CONCLUSION: Pars plana vitrectomy with scleral buckling was found to induce transient changes in corneal topography.

  8. Recombination in the human Pseudoautosomal region PAR1.

    Directory of Open Access Journals (Sweden)

    Anjali G Hinch

    2014-07-01

    Full Text Available The pseudoautosomal region (PAR is a short region of homology between the mammalian X and Y chromosomes, which has undergone rapid evolution. A crossover in the PAR is essential for the proper disjunction of X and Y chromosomes in male meiosis, and PAR deletion results in male sterility. This leads the human PAR with the obligatory crossover, PAR1, to having an exceptionally high male crossover rate, which is 17-fold higher than the genome-wide average. However, the mechanism by which this obligatory crossover occurs remains unknown, as does the fine-scale positioning of crossovers across this region. Recent research in mice has suggested that crossovers in PAR may be mediated independently of the protein PRDM9, which localises virtually all crossovers in the autosomes. To investigate recombination in this region, we construct the most fine-scale genetic map containing directly observed crossovers to date using African-American pedigrees. We leverage recombination rates inferred from the breakdown of linkage disequilibrium in human populations and investigate the signatures of DNA evolution due to recombination. Further, we identify direct PRDM9 binding sites using ChIP-seq in human cells. Using these independent lines of evidence, we show that, in contrast with mouse, PRDM9 does localise peaks of recombination in the human PAR1. We find that recombination is a far more rapid and intense driver of sequence evolution in PAR1 than it is on the autosomes. We also show that PAR1 hotspot activities differ significantly among human populations. Finally, we find evidence that PAR1 hotspot positions have changed between human and chimpanzee, with no evidence of sharing among the hottest hotspots. We anticipate that the genetic maps built and validated in this work will aid research on this vital and fascinating region of the genome.

    To assess personality traits using the Temperament and Character Inventory (TCI) in a group of 63 previously diagnosed ADHD patients and 68 population controls and investigate the impact of common comorbid psychiatric disorders on these personality measures. Psychiatric comorbidity was assessed with the Mini International Neuropsychiatric Interview Plus and personality traits by the TCI. The patient group had significantly higher scores on the TCI dimensions Harm avoidance and Novelty seeking compared with the control group. However, when adjusting for comorbid anxiety and depressive disorder, the ADHD group no longer showed higher Harm avoidance than the control group. The difference in Novelty seeking between the patient and control groups was correlated with lifetime diagnosis of antisocial personality disorder (ASPD). It is important to take comorbid psychiatric disorders into account while investigating personality traits in ADHD. © The Author(s) 2013.

    The present case-control study aims to assess the occurrence of alexithymic traits in burning mouth syndrome (BMS) subjects and to correlate alexithymic traits to anxious and depressive traits in BMS subjects. Prospectively enrolled BMS and control subjects were administered the 20-item Toronto Alexithymia Scale (TAS-20). Anxiety and depressive traits were assessed using the Hamilton Anxiety Rating Scale and the Montgomery and Asberg Depression Rating Scale. Occurrence of alexithymic traits was compared between BMS and control subjects. Correlation tests were used to measure the importance of alexithymic traits related to demographic characteristics, pain intensity (VAS score), and to the other psychometric scores. Fifty-eight BMS subjects (46 females and 12 males) had a mean TAS-20 score significantly higher when compared to controls (p < 0.001; r = 0.72), corresponding to an occurrence rate of alexithymic traits of 79.3 versus 6.9%. Alexithymic traits in BMS subjects were just related to depressive traits (p = 0.02; ρ = 0.31). The high occurrence of alexithymia in BMS is an adjunctive issue in favor of its multifactorial pathogenesis, with a not negligible role for somatization. Clinicians should be aware of the high occurrence of alexithymic traits among BMS subjects as such traits may affect the doctor-patient relationship.

    Full Text Available This review offers an integration of dark leadership styles with dark personality traits. The core of dark leadership consists of Three Nightmare Traits (TNT—leader dishonesty, leader disagreeableness, and leader carelessness—that are conceptualized as contextualized personality traits aligned with respectively (low honesty-humility, (low agreeableness, and (low conscientiousness. It is argued that the TNT, when combined with high extraversion and low emotionality, can have serious (“explosive” negative consequences for employees and their organizations. A Situation-Trait-Outcome Activation (STOA model is presented in which a description is offered of situations that are attractive to TNT leaders (situation activation, situations that activate TNT traits (trait activation, and the kinds of outcomes that may result from TNT behaviors (outcome activation. Subsequently, the TNT and STOA models are combined to offer a description of the organizational actions that may strengthen or weaken the TNT during six career stages: attraction, selection, socialization, production, promotion, and attrition. Except for mainly negative consequences of the TNT, possible positive consequences of TNT leadership are also explored, and an outline of a research program is offered that may provide answers to the most pressing questions in dark leadership research.

    Migraine is one of the most common types of pain associated with sterile inflammatory conditions. Soluble urokinase plasminogen activator receptor (suPAR) is a potential novel inflammatory marker. We aim to determine the association between serum values of suPAR, procalcitonin, fibrinogen, and high-sensitivity C-reactive protein (hs-CRP) and migraine disease characteristics. The study involved a total of 60 migraine patients (33 patients in the interictal period, 27 patients in the attack period) and 30 healthy individuals. The serum values of suPAR were found to be significantly higher in migraine patients in the attack period than in migraine patients in the interictal period, and in healthy individuals (p migraine with aura patients than in migraine without aura patients. When we subdivided migraine patients according to frequency of attack (attacks/month), significant differences were found between the suPAR and procalcitonin levels (measured during the attack period) of those in the frequent-attack group (4-5 or more) versus those in the less frequent attack group (less than 4). Serum levels of procalcitonin were shown to be significantly higher in migraine patients during the attack period compared with migraine patients in the interictal period and in control subjects (p = .001 for both). Significant differences were found between plasma levels of fibrinogen in migraine patients versus control subjects (p migraine patients versus the control group. These findings may show that presenting a high level of suPAR in migraine patients with attack and aura results to predisposition to occurring on the symptoms and that high levels of suPAR, procalcitonin and fibrinogen in patients with migraine result in neurogenic inflammation during migraine headaches.

  17. PARs for combustible gas control in advanced light water reactors

    1997-01-01

    This paper discusses the progress being made in the United States to introduce passive autocatalytic recombiner (PAR) technology as a cost-effective alternative to electric recombiners for controlling combustible gas produced in postulated accidents in both future Advanced Light Water Reactors (ALWRs) and certain U. S. operating nuclear plants. PARs catalytically recombine hydrogen and oxygen, gradually producing heat and water vapor. They have no moving parts and are self-starting and self-feeding, even under relatively cold and wet containment conditions. Buoyancy of the hot gases they create sets up natural convective flow that promotes mixing of combustible gases in a containment. In a non-inerted ALWR containment, two approaches each employing a combination of PARs and igniters are being considered to control hydrogen in design basis and severe accidents. In pre-inerted ALWRs, PARs alone control radiolytic oxygen produced in either accident type. The paper also discusses regulatory feedback regarding these combustible gas control approaches and describes a test program being conducted by the Electric Power Research Institute (EPRI) and Electricite de France (EdF) to supplement the existing PAR test database with performance data under conditions of interest to U.S. plants. Preliminary findings from the EPRI/EdF PAR model test program are included. Successful completion of this test program and confirmatory tests being sponsored by the U. S. NRC are expected to pave the way for use of PARs in ALWRs and operating plants. (author)

    2013-01-01

    Objective: To evaluate the role of early pars plana vitrectomy (PPV) in cases of exogenous endophthalmitis in terms of final visual outcome and to determine association between various study variables and final visual outcome. Study Design: Quasi experimental study. Place and Duration of Study: Armed Forces Institute of Ophthalmology (AFIO) Rawalpindi, from Aug 2010 to May 2012. Patients and Methods: Eleven cases of exogenous endophthalmitis (post surgical/post traumatic) were managed surgically through 20 G or 23/25 G complete and early PPV. Vitreous aspirate/explanted intraocular lens (IOL) were sent for culture and sensitivity in all cases. Intra and post operative complications were recorded and best corrected visual acuity (BCVA) at 3 months post operative interval was taken as final visual acuity. Results: Median age of study population was 55 years with male preponderance (64%). Approximately 2/3 rd of study population developed endophthalmitis within 6 weeks of surgery/trauma and 55% of patients were operated within 2 weeks of presentation. Positive culture from vitreous aspirate/IOL explant was obtained in 27% of cases. All the patients had initial BCVA in the range of counting finger (CF) at 2 meter to perception of light (PL+). However, 18% of the patients achieved final BCVA of 6/12 or better and 64% achieved final BCVA of 6/36 or better. Maculopathy (macular scar, macular pucker), corneal decompensation, corneal opacity and raised intraocular pressure were the major complications associated with compromised visual outcome. Conclusion: With the advancement in vitreoretinal surgical techniques and availability of more sophisticated viewing and illumination systems, early and complete vitrectomy for post operative or post traumatic endophthalmitis results in favorable visual outcome and early rehabilitation.

    The urokinase-type plasminogen activator receptor (uPAR) is a glycosylphosphatidylinositol-linked membrane protein with no cytosolic domain that localizes to lipid raft microdomains. Our laboratory and others have documented that lung fibroblasts from patients with idiopathic pulmonary fibrosis (IPF) exhibit a hypermotile phenotype. This study was undertaken to elucidate the molecular mechanism whereby uPAR ligation with its cognate ligand, urokinase, induces a motile phenotype in human lung fibroblasts. We found that uPAR ligation with the urokinase receptor binding domain (amino-terminal fragment) leads to enhanced migration of fibroblasts on fibronectin in a protease-independent, lipid raft-dependent manner. Ligation of uPAR with the amino-terminal fragment recruited α5β1 integrin and the acylated form of the Src family kinase, Fyn, to lipid rafts. The biological consequences of this translocation were an increase in fibroblast motility and a switch of the integrin-initiated signal pathway for migration away from the lipid raft-independent focal adhesion kinase pathway and toward a lipid raft-dependent caveolin-Fyn-Shc pathway. Furthermore, an integrin homologous peptide as well as an antibody that competes with β1 for uPAR binding have the ability to block this effect. In addition, its relative insensitivity to cholesterol depletion suggests that the interactions of α5β1 integrin and uPAR drive the translocation of α5β1 integrin-acylated Fyn signaling complexes into lipid rafts upon uPAR ligation through protein-protein interactions. This signal switch is a novel pathway leading to the hypermotile phenotype of IPF patient-derived fibroblasts, seen with uPAR ligation. This uPAR dependent, fibrotic matrix-selective, and profibrotic fibroblast phenotype may be amenable to targeted therapeutics designed to ameliorate IPF.

    , and a potential diagnostic and predictive impact of the different uPAR forms has been reported. Hence, pericellular proteolysis seems to be a suitable target for anti-cancer therapy and numerous approaches have been pursued. Targeting of this process may be achieved by preventing the binding of uPA to u...... using mouse monoclonal antibodies (mAbs) against mouse uPA or uPAR. These reagents will target uPA and uPAR in both stromal cells and cancer cells, and their therapeutic potential can now be assessed in syngenic mouse cancer models....

    A limnological database for Par Pond, a cooling reservoir for hot reactor effluent water at the Savannah River Plant, is described. The data are derived from a combination of research and monitoring efforts on Par Pond since 1959. The approximately 24,000-byte database provides water quality, primary productivity, and flow data from a number of different stations, depths, and times during the 22-year history of the Par Pond impoundment. The data have been organized to permit an interpretation of the effects of twenty years of cooling system operations on the structure and function of an aquatic ecosystem

    Apathy and impulsivity are two major comorbid syndromes of Parkinson's disease (PD) that may represent two extremes of a behavioral spectrum modulated by dopamine-dependent processes. PD is characterized by a progressive loss of dopaminergic neurons in the substantia nigra pars compacta to which are attributed the cardinal motor symptoms of the disorder. Dopamine replacement therapy (DRT), used widely to treat these motor symptoms, is often associated with deficits in hedonic processing and motivation, including apathy and depression, as well as impulse control disorders (ICDs). ICDs comprise pathological gambling, hypersexuality, compulsive shopping, binge eating, compulsive overuse of dopaminergic medication, and punding. More frequently observed in males with early onset PD, ICDs are associated not only with comorbid affective symptoms, such as depression and anxiety, but also with behavioral traits, such as novelty seeking and impulsivity, as well as with personal or familial history of alcohol use. This constellation of associated risk factors highlights the importance of inter-individual differences in the vulnerability to develop comorbid psychiatric disorders in PD patients. Additionally, withdrawal from DRT in patients with ICDs frequently unmasks a severe apathetic state, suggesting that apathy and ICDs may be caused by overlapping neurobiological mechanisms within the cortico-striato-thalamo-cortical networks. We suggest that altered hedonic and impulse control processes represent distinct prodromal substrates for the development of these psychiatric symptoms, the etiopathogenic mechanisms of which remain unknown. Specifically, we argue that deficits in hedonic and motivational states and impulse control are mediated by overlapping, yet dissociable, neural mechanisms that differentially interact with DRT to promote the emergence of ICDs in vulnerable individuals. Thus, we provide a novel heuristic framework for basic and clinical research to better

    Proteinase-activated receptors 4 (PAR(4)) is a class A G protein-coupled receptor (GPCR) recognized through the ability of serine proteases such as thrombin and trypsin to mediate receptor activation. Due to the irreversible nature of activation, a fresh supply of receptor is required to be mobilized to the cell surface for responsiveness to agonist to be sustained. Unlike other PAR subtypes, the mechanisms regulating receptor trafficking of PAR(4) remain unknown. Here, we report novel features of the intracellular trafficking of PAR(4) to the plasma membrane. PAR(4) was poorly expressed at the plasma membrane and largely retained in the endoplasmic reticulum (ER) in a complex with the COPI protein subunit β-COP1. Analysis of the PAR(4) protein sequence identified an arginine-based (RXR) ER retention sequence located within intracellular loop-2 (R(183)AR → A(183)AA), mutation of which allowed efficient membrane delivery of PAR(4). Interestingly, co-expression with PAR(2) facilitated plasma membrane delivery of PAR(4), an effect produced through disruption of β-COP1 binding and facilitation of interaction with the chaperone protein 14-3-3ζ. Intermolecular FRET studies confirmed heterodimerization between PAR(2) and PAR(4). PAR(2) also enhanced glycosylation of PAR(4) and activation of PAR(4) signaling. Our results identify a novel regulatory role for PAR(2) in the anterograde traffic of PAR(4). PAR(2) was shown to both facilitate and abrogate protein interactions with PAR(4), impacting upon receptor localization and cell signal transduction. This work is likely to impact markedly upon the understanding of the receptor pharmacology of PAR(4) in normal physiology and disease.

    Full Text Available Spondylolysis of the lumbar spine has traditionally been treated using a variety of techniques ranging from conservative care to fusion. Direct repair of the defect may be utilized in young adult patients without significant disc degeneration and lumbar instability. We used minimally invasive techniques to place pars interarticularis screws with the use of an intraoperative CT scanner in three young adults, including two athletes. This technique is a modification of the original procedure in 1970 by Buck, and it offers the advantage of minimal muscle dissection and optimal screw trajectory. There were no intra- or postoperative complications. The detailed operative procedure and the postoperative course along with a brief review of pars interarticularis defect treatment are discussed.

  8. Positron Accumulator Ring (PAR) power supply

    Fathizadeh, M.

    1995-01-01

    The Positron Accumulator Ring (PAR) consists of 8 dipole magnets connected in series. These magnets are energized via one 12-pulse dc power supply. The power supply consists of four phase controlled half-wave wye group converters. Each of the two half-wave converters are connected through an interphase transformer to obtain a full-wave converter with 120 degrees conduction. The input voltage for these two half-wave converters are 180 degrees apart. The two full-wave converters are connected in parallel through a third interphase transformer. This type of connection of the converters not only provides the required output current, it also improves the input power factor of the power supply. The output of the wye group converters is filtered through a passive L-R-C filter to reduce the ripple content of the output current. At low current values of the power supply the current ripple is high, thus a large filter is needed, which adds to the cost of the power supply, however at high output current levels, the current ripple is less severe. The large size of the filter can be reduced by adding an anti-parallel rectifier diode(D1) to the output of the power supply. A freewheeling diode(D2) is connected before the choke to circulate the current once the power supply is turned off. In order to measure the current in the magnet a high precision, low drift, zero flux current transductor is used. This transductor senses the magnet current which provides a feedback signal to control the gating of the converter's thyristors. A true 14 bit Digital to Analog Converter (DAC) is programmed by the control computer for the required current value, providing a reference for the current regulator. Fast correction of the line transients is provided by a relatively fast voltage loop controlled by a high gain slow response current loop

    To assess changes in MR signal intensity in the pars interarticularis and adjacent structures in patients with lumbar spondylolysis. The MR images of 36 patients with lumbar spondylolysis, confirmed by plain radiographs, were retrospectively analyzed. Using a 1.0T unit, we evaluated the signal intensity of a total of 216 parts interarticulares and adjacent structures from L3 to L5, as seen on sagittal images, and differences between areas with and without spondylolysis. The signal intensity of T1-and T2-weighted images was graded 0(more hypointense than spinal body), 1(as isointense as spinal body), 2(more hyperintense than spinal body and more hypointense than epidural fat), or 3(as isointense as epidural fat). Signal intensity change in endplates and degree of spondylolisthesis were analyzed, and the relationship between these factors was determined. Spondylolysis was noted at L5 in 61 cases, at L4 in 22, and of L3 in no case. In three cases spondylolysis was unilateral, and in the remainder it was bilateral. The degree of signal intensity was the same on T1-and T2-weighted images, and no case was grade 0. Eighty-six of 133 areas without spondylolysis were grade 1, 43 were grade 2, and four were grade 3. In 42 of 47 cases, signal intensity change was localized at pedicles. Among 83 areas with spondylolysis,on the other hand, nine were grade 1, 48 were grade 2, and 26 were grade 3. Signal intensity change was most commonly observed at the pars interarticularis, pedicle, and lamina(50/74)({rho}<0.001). Signal intensity change at the pars interarticularis and adjacent structures was accompanied in most cases by degenerative endplate change(10/11) and spondylolisthesis(11/13)({rho}<0.001). In patients with spondylolysis, signal intensity was frequently higher at the pars interarticularis and adjacent structures, and is thought to have a close relationship with degenerative endplate change and spondylolisthesis.

    Full Text Available Bacterial centromeres-also called parS, are cis-acting DNA sequences which, together with the proteins ParA and ParB, are involved in the segregation of chromosomes and plasmids. The specific binding of ParB to parS nucleates the assembly of a large ParB/DNA complex from which ParA-the motor protein, segregates the sister replicons. Closely related families of partition systems, called Bsr, were identified on the chromosomes and large plasmids of the multi-chromosomal bacterium Burkholderia cenocepacia and other species from the order Burkholeriales. The centromeres of the Bsr partition families are 16 bp palindromes, displaying similar base compositions, notably a central CG dinucleotide. Despite centromeres bind the cognate ParB with a narrow specificity, weak ParB-parS non cognate interactions were nevertheless detected between few Bsr partition systems of replicons not belonging to the same genome. These observations suggested that Bsr partition systems could have a common ancestry but that evolution mostly erased the possibilities of cross-reactions between them, in particular to prevent replicon incompatibility. To detect novel similarities between Bsr partition systems, we have analyzed the binding of six Bsr parS sequences and a wide collection of modified derivatives, to their cognate ParB. The study was carried out by Surface Plasmon Resonance imaging (SPRi mulitplex analysis enabling a systematic survey of each nucleotide position within the centromere. We found that in each parS some positions could be changed while maintaining binding to ParB. Each centromere displays its own pattern of changes, but some positions are shared more or less widely. In addition from these changes we could speculate evolutionary links between these centromeres.

    Drug resistance and drug-associated toxicity are the primary causes for withdrawal of many drugs, although patient recovery is satisfactory in many instances. Interestingly, the use of phytochemicals in the treatment of cancer as an alternative to synthetic drugs comes with a host of advantages; minimum side effects, good human absorption and low toxicity to normal cells. Protease activated receptor 1 (PAR1) has been established as a promising target in many diseases including various cancers. Strong evidences suggest its role in metastasis also. There are no natural compounds known to inhibit its activity, so we aimed to identify phytochemicals with antagonist activity against PAR1. We screened phytochemicals from Naturally Occurring Plant-based Anticancer Compound-Activity-Target database (NPACT, http://crdd.osdd.net/raghava/npact/ ) against PAR1 using virtual screening workflow of Schrödinger software. It analyzes pharmaceutically relevant properties using Qikprop and calculates binding energy using Glide at three accuracy levels (high-throughput virtual screening, standard precision and extra precision). Our study led to the identification of phytochemicals, which showed interaction with at least one experimentally determined active site residue of PAR1, showed no violations to Lipinski's rule of five along with predicted high human absorption. Furthermore, structural interaction fingerprint analysis indicated that the residues H255, D256, E260, S344, V257, L258, L262, Y337 and S344 may play an important role in the hydrogen bond interactions of the phytochemicals screened. Of these residues, H255 and L258 residues were experimentally proved to be important for antagonist binding. The residues Y183, L237, L258, L262, F271, L332, L333, Y337, L340, A349, Y350, A352, and Y353 showed maximum hydrophobic interactions with the phytochemicals screened.

    There has been significant movement toward conceptualizing borderline personality disorder (BPD) with normal personality traits. However one critical assumption underlying this transition, that longitudinal trajectories of BPD symptoms and normal traits track together, has not been tested. We evaluated the prospective longitudinal associations of changes in five-factor model traits and BPD symptoms over the course of 16 years using parallel process latent growth curve models in 362 patients with BPD (N=290) or other PDs (N=72). Moderate to strong cross-sectional and longitudinal associations were observed between BPD symptoms and Neuroticism, Extraversion, Agreeableness, and Conscientiousness. This study is the first to demonstrate a longitudinal link between changes in BPD symptoms and changes in traits over an extended interval in a clinical sample. These findings imply that changes in BPD symptoms occur in concert with changes in normal traits, and support the proposed transition to conceptualizing BPD, at least in part, with trait dimensions.

    Postconcussion symptoms (PCS) are not uncommon following mild traumatic brain injury (mTBI). Personality traits have always been viewed as one of the most important explanations for persistent postconcussion symptoms (PPCS). Unfortunately, studies on the association between preinjury personality traits and the PPCS are still limited. This study thus aimed to examine the relationship between the preinjury personality and PCS in patients with mTBI. A total of 106 participants including 53 healthy participants were recruited. All participants complete the modified Checklist of Postconcussion Symptoms and the Health, Personality, & Habit Scale. Participants were evaluated within 4 weeks and at 4 months, respectively, after injury. The results showed patients reported significantly more PCS than healthy participants did within 4 weeks postinjury. A significant positive association between PCS and retrospectively evaluated preinjury personality was found. Specifically, patients who reported that their preinjury personality was depressive or anxious-related presented more PCS. This study might be the first to directly demonstrate that preinjury personality traits are closely linked to PCS reporting in patients with mTBI. Importantly, PCS reporting might be associated with different personality traits at different periods after injuries, and thus, a careful evaluation for personality characteristics is merited after mTBI.

    The essential targets of dry eye disease (DED) treatments include both objective signs and subjective symptoms. However, due to the numerous subjective symptoms, it is understandable why little association has been found between the signs and symptoms. Although psychological influences on the subjective symptoms have been reported, little is known about the influence of personality traits. The present study analyzed the relationship between the signs/symptoms of DED and the personality traits of patients using a cross-sectional design. We examined 56 DED patients (mean age; 62.4 ± 12.9, range 34-85 years) visiting the outpatient clinic of the Department of Ophthalmology at the Nippon Medical School Hospital in Tokyo, Japan. Objective signs evaluated included the Schirmer I test, tear breakup time (BUT), fluorescein and lissamine green staining, and tear osmolality. Subjective symptoms were assessed by the Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-Life Score (DEQS) questionnaires. For personality traits, the Big Five personality traits model analysis was used. Correlations between the objective signs, subjective symptoms, and personality traits were analyzed. A significant correlation was found between the neuroticism in the Big Five Personality Inventory and the symptoms assessed by the DEQS (r = -0.35, p personality traits. The results of our current study suggest that the personality of the patient, which appears to be the basis of various psychological factors, can have some impact on the subjective symptoms. This may be one of the reasons why there has been little association noted between the signs and symptoms of DED.

    BACKGROUND: High blood levels of soluble urokinase Plasminogen Activator Receptor (suPAR) are associated with poor outcomes in human immunodeficiency-1 (HIV-1) infected individuals. Research on the clinical value of suPAR in HIV-1 infection led to the development of the suPARnosticTM assay...... for commercial use in 2006. The aim of this study was to: 1) Evaluate the prognostic value of the new suPARnosticTM assay and 2) Determine whether polymorphisms in the active promoter of uPAR influences survival and/or suPAR values in HIV-1 patients who are antiretroviral therapy (ART) naive. METHODS: DNA...... and an A to G transition at -465 comparative to the transcription start site. These promoter transitions did not influence neither the suPAR levels nor patient survival. CONCLUSION: Plasma suPAR levels, as measured by the suPARnosticTM assay, were strongly predictive of survival in ART-naive HIV-1 infected...

  8. Ecological interactions drive evolutionary loss of traits.

    Loss of traits can dramatically alter the fate of species. Evidence is rapidly accumulating that the prevalence of trait loss is grossly underestimated. New findings demonstrate that traits can be lost without affecting the external phenotype, provided the lost function is compensated for by species interactions. This is important because trait loss can tighten the ecological relationship between partners, affecting the maintenance of species interactions. Here, we develop a new perspective on so-called `compensated trait loss' and how this type of trait loss may affect the evolutionary dynamics between interacting organisms. We argue that: (1) the frequency of compensated trait loss is currently underestimated because it can go unnoticed as long as ecological interactions are maintained; (2) by analysing known cases of trait loss, specific factors promoting compensated trait loss can be identified and (3) genomic sequencing is a key way forwards in detecting compensated trait loss. We present a comprehensive literature survey showing that compensated trait loss is taxonomically widespread, can involve essential traits, and often occurs as replicated evolutionary events. Despite its hidden nature, compensated trait loss is important in directing evolutionary dynamics of ecological relationships and has the potential to change facultative ecological interactions into obligatory ones. © 2012 Blackwell Publishing Ltd/CNRS.

    The objectives of this study were to explore associations between autistic traits and self-reported clinical symptoms in a population with anorexia nervosa (AN). Experimental and self-report evidence reveals similarities between AN and autism spectrum condition (ASC) populations in socio-emotional and cognitive domains; this includes difficulties with empathy, set-shifting and global processing. Focusing on these similarities may lead to better tailored interventions for both conditions. A cross-sectional independent-groups design was employed. Participants with AN (n = 66) and typical controls (n = 66) completed self-report questionnaires including the Short (10-Item) Version Autism Spectrum Quotient (AQ-10) questionnaire (the first time this has been implemented in this population), the Eating Disorder Examination Questionnaire, the Hospital Anxiety and Depression Scale and the Work and Social Adjustment Scale. Group differences and the relationship between autistic traits and other questionnaire measures were investigated. The AN group had a significantly higher AQ-10 total score and a greater proportion scored above the clinical cut-off than the control group. Seven out of ten AQ-10 items significantly discriminated between groups. In the AN group, levels of autistic traits correlated with a greater self-reported anxiety and depression and a lower ability to maintain close relationships; however, eating disorder symptoms were not associated with autistic traits. Women with anorexia possess a greater number of autistic traits than typical women. AQ-10 items that discriminated between groups related to 'bigger picture' (global) thinking, inflexibility of thinking and problems with social interactions, suggesting that autistic traits may exacerbate factors that maintain the eating disorder rather than cause the eating disorder directly. Using screening instruments may improve understanding of patients' problems, leading to better tailoring of intervention. We

    The water level of Par Pond was lowered approximately 20 feet in mid-1991 in order to protect downstream residents from possible dam failure suggested by subsidence on the downstream slope of the dam and to repair the dam. This lowering exposed both emergent and nonemergent macrophyte beds to drying conditions resulting in extensive losses. A survey of the shoreline aquatic plant communities in June 1995, three months after the refilling of Par Pond to approximately 200 feet above mean sea level, indicated that much of the original plant communities and the intermediate shoreline communities present on the exposed sediments have been lost. The extensive old-field and emergent marsh communities that were present on the exposed shoreline during the drawdown have been flooded and much of the pre-drawdown Par Pond aquatic plant communities have not had sufficient time for re-establishment. The shoreline does, however, have extensive beds of maidencane which extend from the shoreline margin to areas as deep as 2 and perhaps 3 meters. Scattered individual plants of lotus and watershield are common and may indicate likely directions of future wetland development in Par Pond. In addition, within isolated coves, which apparently received ground water seepage and/or stream surface flows during the period of the Par Pond draw down, extensive beds of waterlilies and spike rush are common. Invasion of willow and red maple occurred along the lake shoreline as well. Although not absent from this survey, evidence of the extensive redevelopment of the large cattail and eel grass beds was not observed in this first survey of Par Pond. Future surveys during the growing seasons of 1995, 1996, and 1997 along with the evaluation of satellite date to map the areal extent of the macrophyte beds of Par Pond are planned

    La douleur induite par les soins correspond à la douleur survenant lors des actes à visé diagnostique et/ou thérapeutique. A notre connaissance, nous n'avons pas encore des données disponibles pour les douleurs induites par les soins à l'Hôpital de Befelatanana. Nos objectifs étaient de décrire le profil épidémiologique de la douleur induite par les soins, d'identifier les principaux facteurs influençant sur l'intensité de la douleur et leurs retentissements chez les patients. Il s'agissait d'une étude rétrospective, transversale type un jour donné menée dans les douze services de Médecines au Centre Hospitalier Universitaire de Befelatanana en Novembre 2013. Cent deux patients ont été retenus dans l’étude et trois cent vingt trois actes douloureux étaient enregistrés. La fréquence de la douleur induite par les soins était de 69,86%. Le genre féminin prédominait dans 52% des cas (n = 53) avec un sex-ratio à 0,92. L’âge moyen était de 46 ans. Les ponctions vasculaires étaient l'acte prédominant dans 49,54% (n = 109) des cas. Les infirmiers réalisaient les soins dans 47,05% (n = 48) des cas. L'information verbale était la mesure préventive utilisée dans 57,84% des cas (n = 59). Le transport par marche à pied et au dos représentait 16,67% des cas (n = 17). Les patients naïfs des gestes étaient plus anxieux.

    Personality is one of important factors in the pathogenesis of schizophrenia because it affects patients' symptoms, cognition and social functioning. Several studies have reported specific personality traits in patients with schizophrenia compared with healthy subjects. However, the results were inconsistent among studies. The NEO Five-Factor Inventory (NEO-FFI) measures five personality traits: Neuroticism (N), Extraversion (E), Openness (O), Agreeableness (A) and Conscientiousness (C). Here, we performed a meta-analysis of these personality traits assessed by the NEO-FFI in 460 patients with schizophrenia and 486 healthy subjects from the published literature and investigated possible associations between schizophrenia and these traits. There was no publication bias for any traits. Because we found evidence of significant heterogeneity in all traits among the studies, we applied a random-effect model to perform the meta-analysis. Patients with schizophrenia showed a higher score for N and lower scores for E, O, A and C compared with healthy subjects. The effect sizes of these personality traits ranged from moderate to large. These differences were not affected by possible moderator factors, such as gender distribution and mean age in each study, expect for gender effect for A. These findings suggest that patients with schizophrenia have a different personality profile compared with healthy subjects. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    A new surface treatment technique with a primary explosive deposited in thin layer was applied to a polycrystalline pure copper. After treatment, surface roughness remains of high quality especially when compared to shot peened surfaces. The treated zone extends over several hundreds microns in depth and the microhardness profile exhibits a significant increasing of hardness with a maximum reaching 100% at the surface. The transmission electron microscopy shows a microstructure which changes with depth : below the surface, there is a thin recrystallized layer with very small grains followed by a region with numerous mechanical twins the density of which decreases when depth increases. Tested in fatigue with a constant plastic strain amplitude, the treated copper specimens exhibit a strong hardening from the first cycles compared to the untreated specimen ; however this initial hardening erases after 2% of the fatigue life. The fatigue resistance is not modified by the treatment. Une nouvelle technique de traitement de surface à l'aide d'un explosif primaire déposé en couche mince a été utilisée sur du cuivre pur polycristallin. L'état de surface après traitement reste de très bonne qualité, surtout comparé aux surfaces grenaillées. La zone traitée s'étend sur une profondeur de quelques centaines de microns et le profil de microdureté montre une importante augmentation de dureté avec un maximum en surface pouvant atteindre 100%. La micrcrostructure, observée par microscopie électronique en transmission, est caractérisée par une fine recristallisation en surface, puis par un abondant maclage dont la densité décroît lorsque la profondeur augmente. Testé en fatigue à déformation plastique imposée, le cuivre traité présente un fort écrouissage initial dès les premiers cycles, mais qui s'efface progressivement au cours du cyclage après 2% de la durée de vie, cette dernière n'étant pas modifiée par le traitement.

    Loss of traits can dramatically alter the fate of species. Evidence is rapidly accumulating that the prevalence of trait loss is grossly underestimated. New findings demonstrate that traits can be lost without affecting the external phenotype, provided the lost function is compensated for by species

    Is it possible to improve vascular remodeling by inhibiting the excessive expression of protease-activated receptor 1 (PAR-1) in trophoblast of abnormal placenta? Inhibition of trophoblast PAR-1 overexpression may promote placental angiogenesis and vascular remodeling, offering an alternative therapeutic approach for preeclampsia. PAR-1 is high-affinity receptor of thrombin. Thrombin increases sFlt-1 secretion in trophoblast via the activation of PAR-1. It is reported that the expression of both thrombin and PAR-1 expression are increased in placentas of preeclampsia patients compared with normal placentas. Trophoblast cells were transfected with PAR-1 short hairpin RNA (shRNA) or PAR-1 overexpression plasmids in vitro. Tube formation assays and a villus-decidua co-culture system were used to study the effect of PAR-1 inhibition on placental angiogenesis and vascular remodeling, respectively. Placentas from rats with preeclampsia were transfected with PAR-1 shRNA to confirm the effect of inhibiting PAR-1 overexpression in placenta. The trophoblast cell line HTR-8/SVneo was transfected with PAR-1 shRNA or PAR-1 overexpression plasmids. After 48 h, supernatant was collected and the level of sFlt-1 secretion was measured by ELISA. Human umbilical cord epithelial cells and a villus-decidua co-culture system were treated with conditioned media to study the effect of PAR-1 inhibition on tube formation and villi vascular remodeling. A preeclampsia rat model was established by intraperitoneal injection of L-NAME. Plasmids were injected into the placenta of the preeclampsia rats and systolic blood pressure was measured on Days 15 and 19. The effect of different treatments was evaluated by proteinuria, placental weights, fetal weights and fetal numbers in study and control groups. The level of serum sFlt-1 in rats with preeclampsia was also measured. Changes in the placenta microvessels were studied by histopathological staining. PAR-1 shRNA inhibited PAR-1 expression and

    Full Text Available The effects of organic and inorganic nitrogen fertilization on some physiological and agronomical traits of chickpea (Cicer arietinum L. cv. ILC 482, investigated at the Experimental Farm of the Agriculture Faculty, University of Mohaghegh Ardabili. The trial was laid out in spilt plot design based on randomized complete block with four replications. Experimental factors were mineral nitrogen fertilizer at four levels (0, 50, 75 and 100 kg urea/ha in the main plots, and two levels of inoculation with Rhizobium bacteria (with and without inoculation as sub plots. N application and Rh. inoculation showed positive effects on physiological and agronomical traits of chickpea. The highest value of leaf RWC recorded in 50 kg urea/ha that was statistically in par with 75 kg urea/ha application while, usage of 75 kg urea/ha showed the maximum stem RWC. The maximum CMS obtained form application of 75 kg urea/ha. Chlorophyll content, leaf area index and grains protein content showed their maximum values in the highest level of nitrogen usage (100 kg urea/ha. Moreover, inoculated plants had the highest magnitudes of all physiological traits. In the case of agronomical traits, the highest values of plant height, number of primary and secondary branches, number of pods per plant, number of grains per plant, grain and biological yield were obtained from the highest level of nitrogen fertilizer (100 kg urea/ha and Rh. inoculation. Application of 75 kg urea/ha was statistically in par with 100 kg urea/ha in all of these traits. The results pointed out that some N fertilization (i.e. between 50 and 75 kg urea/ha as starter can be beneficial to improve growth, development, physiological traits and total yield of inoculated chickpea.

    Ambroise Paré died December the 20th., 1590. What happened after his death and what are we knowing about his life? Never forgotten, though a lack of care, we were waiting till the XIXth. century to get recollection upon a subject sustained only by accounts of his travels. After Percy, a surgeon who tried to write Paré's biography through the "Biographie universelle ancienne et moderne, de Michaud (1822)" and some second rank authors, Malgaigne is the first who inside a printing of the "Oeuvres complétes de Paré (1840-41)" has a fine look upon the question, though his work is incomplete and allows many mistakes. Doctors Chéreau and Jal, an historian, analysing civil status records, gave new information enlarged by doctors Le Paulmier, Turner and the U.S. native Janet Doe.

    John James authored two key papers on the theory of risk to relatives for binary disease traits and the relationship between parameters on the observed binary scale and an unobserved scale of liability (James Annals of Human Genetics, 1971; 35: 47; Reich, James and Morris Annals of Human Genetics, 1972; 36: 163). These two papers are John James' most cited papers (198 and 328 citations, November 2014). They have been influential in human genetics and have recently gained renewed popularity because of their relevance to the estimation of quantitative genetics parameters for disease traits using SNP data. In this review, we summarize the two early papers and put them into context. We show recent extensions of the theory for ascertained case-control data and review recent applications in human genetics. © 2015 Blackwell Verlag GmbH.

    To compare the diagnostic accuracy of 3-T magnetic resonance imaging (MRI) with thin-slice 3D T1 VIBE sequence to 128-slice computer tomography (CT) in pars stress fractures of the lumbar spine. 3-T MRI and CT of 24 patients involving 70 pars interarticularis were retrospectively reviewed by four blinded radiologists. The fracture morphology (complete, incomplete, or normal) was assessed on MRI and CT at different time points. Pars interarticularis bone marrow edema (present or absent) was also evaluated on MRI. In total, 14 complete fractures, 31 incomplete fractures and 25 normal pars were detected by CT. Bone marrow edema was seen in seven of the complete and 25 of the incomplete fractures. The overall sensitivity, specificity and accuracy of MRI in detecting fractures (complete and incomplete) were 97.7, 92.3, and 95.7 %, respectively. MRI was 100 % accurate in detecting complete fractures. For incomplete fractures, the sensitivity, specificity, and accuracy of MRI were 96.7, 92.0, and 94.6 %, respectively. 3-T MRI with thin-slice 3D T1 VIBE is 100 % accurate in diagnosing complete pars fractures and has excellent diagnostic ability in the detection and characterization of incomplete pars stress fractures compared to CT. MRI has the added advantages of detecting bone marrow edema and does not employ ionizing radiation. (orig.)

    Léri-Weill dyschondrosteosis (LWD) is a skeletal dysplasia characterized by disproportionate short stature and Madelung deformity. Mutations or deletions of the SHOX gene have been previously identified as the main cause of LWD. We recently identified the existence of a second class of pseudoautosomal region 1 (PAR1) deletions which do not include SHOX, implicated in the etiopathogenesis of LWD. The deletions map at least 30-250 kb downstream of SHOX, are variable in size and clearly cosegregate with the LWD phenotype. In order to determine the frequency of this new type of deletions in the Spanish population we analyzed the distribution of PAR1 defects, including the screening of SHOX deletions, mutations, and PAR1 deletions downstream of SHOX, in a total of 26 LWD probands by a combination of MLPA, microsatellite analysis, SNP genotyping, dHPLC, and DNA sequencing. A molecular defect was identified in 16/26 LWD patients (61.5%): 10 PAR1 deletions downstream of SHOX, four SHOX encompassing deletions, and two SHOX mutations. No apparent phenotypic differences were observed between patients with SHOX defects and those with PAR1 deletions downstream of SHOX. In the examined cohort of Spanish LWD probands, PAR1 deletions downstream of SHOX represent the highest proportion of identified mutations (38%) compared to SHOX deletions (15%) and mutations (8%). As a consequence of our findings, the screening of this region should be included in the routine genetic testing of LWD. Also, LWD patients who tested negative for SHOX defects should be re-evaluated for PAR1 deletions downstream of SHOX.

    In this process, the uranium fuel is clad with a zirconium can by passing the element through a die. The operation takes place at a temperature varying between 500 and 1000 deg. C. The heating is obtained by passing low voltage electric current through the can. This process differs from the co-extrusion process in that the uranium is not deformed. The uranium is therefore machined to the final dimensions before canning, it can also be hollow. Two types of processes can be adopted for the extrusion: a) Process in which the binding of the can to the uranium is obtained without diffusion (here the can is at high temperature - subsequently cooled - and the uranium is at a low temperature); b) Process in which uranium-zirconium diffusion is initiated. No matter which process is adopted the element is subsequently heat treated in an over at 800 deg. C in order to obtain the final diffusion. The quality of this diffusion is dependent on the initial state of the surfaces and on the degree of vacuum maintained during the operation. (author) [French] Dans ce procede, la gaine zirconium est plaquee sur le combustible uranium par passage dans une filiere. L'operation a lieu a chaud, a une temperature variant entre 500 et 1000 deg. C. Le chauffage est assure par passage d'un courant basse tension dans la gaine. A la difference du procede de cofilage, l'uranium ne subit pas de deformation durant l'operation. Il est donc prealablement usine aux cotes definitives et peut etre creux. Deux processus sont possibles pendant le passage dans la filiere: a) Obtention d'un frettage de la gaine sur l'uranium sans diffusion (avec une gaine a haute temperature et un tube d'uranium a basse temperature, eventuellement refroidi); b) Obtention d'un commencement de diffusion uranium-zirconium. Quelque soit le processus adopte, la cartouche est ensuite traitee dans un four a 800 deg. C pour obtenir la diffusion definitive.

Les problèmes de distribution de taille et de vitesse d'injection des particules sont également abordés car ils conditionnent les distributions de trajectoires et donc le traitement des particules dans le jet de plasma. La génération du plasma montre d'une part 1'influence considérable de l'injection du gaz, de sa nature, du dessin de la chambre d'arc et de la tuyère ainsi que du pompage de l'air ambiant sur la longueur des jets de plasma d'arc et d'autre part les problèmes d'injection pour éviter le couplage avec la décharge dans les jets de plasmas R.E Tout ceci est illustré avec des exemples de dépôt d'alumine, de zircone, de cermet carbure et de nickel. L'écrasement des particules est ensuite abordé avec les problèmes de réactions chimiques, de trempe ultra-rapide et donc de structure cristalline des dépôts, d'adhdsion mais aussi de containtes résiduelles et de leur contrôle via les gradients de température dans les dépôts pendant le tir.

    Full Text Available INTRODUCTION: Human cytomegalovirus is an opportunistic betaherpesvirus that causes persistent and serious infections in immunodeficient patients. Recurrent infections occur due to the presence of the virus in a latent state in some cell types. It is possible to examine the virus using molecular methods to aid in the immunological diagnosis and to generate a molecular viral profile in immunodeficient patients. The objective of this study was to characterize cytomegalovirus genotypes and to generate the epidemiological and molecular viral profile in immunodeficient patients. METHODS: A total of 105 samples were collected from immunodeficient patients from the City of Belém, including newborns, hemodialysis patients, transplant recipients and HIV+ patients. An IgG and IgM antibody study was completed using ELISA, and enzymatic analysis by restriction fragment length polymorphism (RFLP was performed to characterize viral genotypes. RESULTS: It was observed that 100% of the patients had IgG antibodies, 87% of which were IgG+/IgM-, consistent with a prior infection profile, 13% were IgG+/IgM+, suggestive of recent infection. The newborn group had the highest frequency (27% of the IgG+/IgM+ profile. By RFLP analysis, only one genotype was observed, gB2, which corresponded to the standard AD169 strain. CONCLUSIONS: The presence of IgM antibodies in new borns indicates that HCMV continues to be an important cause of congenital infection. The low observed genotypic diversity could be attributed to the small sample size because newborns were excluded from the RFLP analysis. This study will be continued including samples from newborns to extend the knowledge of the general and molecular epidemiology of HCMV in immunodeficient patients.INTRODUÇÃO: O citomegalovírus é um betaherpesvírus oportunista, causador de infecções persistentes e graves em pacientes imunodeficientes.

    Gaucher Disease is an autosomal recessive disease caused by the accumulation of glucocerebrosidase due to deficiency in lysosomal glucocerebrosidase. Thalassaemia trait is asymptomatic and is usually an incidental diagnosis. Both thalassaemia and Gaucher disease can have similar haematologic manifestations and hence, their coexistence causes diagnostic dilemma. Our patient presented at one-and-a-half years with weakness, pallor, failure to thrive and massive hepatosplenomegaly. Clinical examination and history pointed to a lipid storage disease. Peripheral smear revealed microcytic hypochromic cells and nucleated red cells with haemolytic blood picture. Thalassaemia trait was indicated on haemoglobin variant analysis using High Performance Liquid Chromatography. Liver biopsy, bone marrow aspirate and therapeutic splenectomy revealed Gaucher-like cells. Type 1 Gaucher disease can be clinically asymptomatic as well as present with massive liver and spleen enlargement and involvement of bone marrow. Anaemia, splenomegaly and thrombocytopenia are the usual presentations at diagnosis, similar to the haemoglobinopathies. Gaucher-like cells with normal beta-glucocerebrosidase (pseudo-Gaucher cells) are seen in thalassaemia, leukaemia, mycobacterial infections and myeloma. Gaucher disease coexisting with thalassaemia trait is uncommon. We report the occurrence of thalassaemia trait and Gaucher disease in a child, which resulted in confusion regarding the haematological diagnosis. This report highlights the necessity of independent establishment of the diagnosis in every patient so that appropriate management decisions are taken.

    Ten to twenty percent of patients with total knee arthroplasty (TKA) are dissatisfied with their clinical outcome. Aim of this study was to investigate the impact of personality traits on the subjective outcome of TKA. We investigated 80 patients with 86 computer navigated TKAs. We asked for patients satisfaction and divided patients into two groups (satisfied or dissatisfied). 12 personality traits were tested by the Freiburg Personality Inventory (FPI-R). Postoperative examination included Knee Society Score (KSS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and the Visual Analogue Scale (VAS). Radiologic investigation was done in all patients. 84% of our patients were satisfied, while 16% were not satisfied. The FPI-R showed statistical significant influence of four personality traits on patient satisfaction: life satisfaction (p = 0.006), performance orientation (p = 0.015), somatic distress (p = 0.001), and emotional stability (p = 0.002). All clinical scores (VAS, WOMAC, and KSS) showed significantly better results in the satisfied patient. Radiological examination showed optimal alignment of all TKAs. There were no complications requiring revision surgery. The results of our study show that personality traits may influence patients satisfaction and clinical outcome after TKA. Therefore patients personality traits may be a useful predictive factor for postoperative satisfaction after TKA.

    Myotonic dystrophy type 1 (DM1), the most common muscular dystrophy observed in adults, is a genetic multisystem disorder affecting several other organs besides skeletal muscle, including the brain. Cognitive and personality abnormalities have been reported; however, no studies have investigated brain functional networks and their relationship with personality traits/disorders in patients with DM1. To use resting-state functional magnetic resonance imaging to assess the potential relationship between personality traits/disorders and changes to functional connectivity within the default mode network (DMN) in patients with DM1. We enrolled 27 patients with genetically confirmed DM1 and 16 matched healthy control individuals. Patients underwent personality assessment using clinical interview and Minnesota Multiphasic Personality Inventory-2 administration; all participants underwent resting-state functional magnetic resonance imaging. Investigations were conducted at the Istituto di Ricovero e Cura a Carattere Scientifico Santa Lucia Foundation, Catholic University of Sacred Heart, and Azienda Ospedaliera San Camillo Forlanini. Resting-state functional magnetic resonance imaging. Measures of personality traits in patients and changes in functional connectivity within the DMN in patients and controls. Changes in functional connectivity and atypical personality traits in patients were correlated. We combined results obtained from the Minnesota Multiphasic Personality Inventory-2 and clinical interview to identify a continuum of atypical personality profiles ranging from schizotypal personality traits to paranoid personality disorder within our DM1 patients. We also demonstrated an increase in functional connectivity in the bilateral posterior cingulate and left parietal DMN nodes in DM1 patients compared with controls. Moreover, patients with DM1 showed strong associations between DMN functional connectivity and schizotypal-paranoid traits. Our findings provide novel

    A survey of the emergent shoreline aquatic plant, communities began in June 1995, three months after the refilling of Par Pond to approximately 200 feet (61 meters) above mean sea level, and continued with this July survey. Aquatic plant communities, similar to the pre-drawdown Par Pond communities, are becoming reestablished. Beds of maidencane (Panicum hemitomon), lotus (Nelumbo lutea), water lily (Nymphaea odorata), and watershield (Brasenia schreberi) are now extensive and well established. In addition, within isolated coves, extensive beds of water lilies and spike-rush (Eleocharis sp.) are common. Cattail occurrence has increased since refill, but large beds common to Par Pond prior to the drawdown have not formed. Invasion of willow (Salix sp.) and red maple (Acer rubrum) occurred along the lake shoreline during drawdown. The red maples along the present shoreline are beginning to show evidence of stress and mortality from flooding over the past four months. Some of the willows appear to be stressed as well. The loblolly pines (Pinus taeda), which were flooded in all but the shallow shoreline areas, are now dead. Future surveys are planned for the growing seasons of 1995, 1996, and 1997, along with the evaluation of satellite data for mapping the areal extent of the macrophyte beds of Par Pond

    2018-02-01

    Extant literature indicates that childhood maltreatment is significantly associated with personality disorders. With the recent call for a more dimensional approach to understanding personality and pathological personality traits, the aim of the present study was to examine whether the experience of childhood maltreatment is associated with pathological personality traits as measured by the Personality Psychopathology Five (PSY-5). We analyzed data from 557 adult psychiatric patients with diverse psychiatric diagnoses, including mood disorders, schizophrenia spectrum disorders, and anxiety disorders. Hierarchical multiple regression analyses were conducted to determine the degree to which childhood maltreatment explained the five trait dimensions after controlling for demographic variables, presence of psychotic symptoms, and degree of depressive symptoms. Childhood maltreatment significantly predicted all of the five trait dimensions of the PSY-5. This suggests that childhood maltreatment may negatively affect the development of an adaptive adjustment system, thereby potentially contributing to the emergence of pathological personality traits.

    Onset of psoriasis may occur at any age. Early negative experiences often influence personality development, and may lead to physical disease, anxiety and depression in adulthood. Knowledge about onset of psoriasis and psychopathology is limited. To examine whether patients with early-onset psoriasis differ psychologically from patients with late-onset psoriasis, regarding personality traits, anxiety and depression. A descriptive cross-sectional study was conducted among 101 consecutively recruited outpatients with psoriasis. A psychosocial interview was performed followed by self-assessment of validated questionnaires: Swedish Universities Scales of Personality (SSP), Spielberger State-Trait Anxiety Inventory and Beck Depression Inventory. Psoriasis severity was assessed by the Psoriasis Area and Severity Index. Patients with early-onset psoriasis (age personality traits: SSP-embitterment, -trait irritability, -mistrust and -verbal trait aggression. Our results indicate that early detection of psychological vulnerability when treating children and adolescents with psoriasis seems to be of great importance. Traits of psychological vulnerability and pessimistic personality traits were found to be significantly associated with the early onset of psoriasis, but not with disease duration in this study. These traits may be seen as a consequence of psoriasis, and/or as individual traits modulating and impairing clinical course and efforts to cope with psoriasis. © 2013 The Authors BJD © 2013 British Association of Dermatologists.

    Lumbar spine radiographs and radionuclide images were compared and correlated with clinical histories of 20 athletes with low back pain. Radiographs were classified as: Normal (Type 0); showing a healing stress fracture (an irregular lucent line) with sclerosis (Type I); as an evolving or healed stress injury with either sclerosis, narrowing, or demineralization (Type II); and as a chronic fracture showing a large lucency with well-defined margins classically referred to as spondylolysis (Type III). Patients were grouped clinically on the basis of their pain: acute onset (Group A, n = 7), acute superimposed on chronic (Group B, n = 9), and chronic pain without an acute event (Group C, n = 4). Radiographic abnormalities were present in 95% (19/20) of the patients and radionuclide studies were positive in 60% (12/20). Scintigraphy was positive most often with Type I pars abnormalities (77%, 10/13) and negative most often with Type III abnormalities (91%, 11/12). Of all positive scintigraphy 12/14 (86%) were in pts in Groups A and B (acute symptoms). The authors' findings support theories that radiographic pars abnormalities exist which correspond to stages in the healing of stress induced fractures. With acute symptoms radionuclide imaging need not be obtained if a Type I radiographic abnormality is seen. Radionuclide imaging is indicated with either Type 0, II or III radiographs to confirm or rule out recent stress injury.

Patients were grouped clinically on the basis of their pain: acute onset (Group A, n = 7), acute superimposed on chronic (Group B, n = 9), and chronic pain without an acute event (Group C, n = 4). Radiographic abnormalities were present in 95% (19/20) of the patients and radionuclide studies were positive in 60% (12/20). Scintigraphy was positive most often with Type I pars abnormalities (77%, 10/13) and negative most often with Type III abnormalities (91%, 11/12). Of all positive scintigraphy 12/14 (86%) were in pts in Groups A and B (acute symptoms). The authors' findings support theories that radiographic pars abnormalities exist which correspond to stages in the healing of stress induced fractures. With acute symptoms radionuclide imaging need not be obtained if a Type I radiographic abnormality is seen. Radionuclide imaging is indicated with either Type 0, II or III radiographs to confirm or rule out recent stress injury
