In 1927, the Nationalist government launched an ambitious project to transform Nanjing into a modern capital. During this reconstruction process, private lands were seized in the name of public interest for the construction of public works. In the face of opposition from affected landowners, Nationalist leaders shifted the emphasis from ‘public interest’ (gonggong liyi) to ‘public obligation’ (shimin zeren), stressing the duty of urban residents to support capital reconstruction and stigmatizing opponents as anti-development. This article examines compulsory land expropriation in Nationalist China and shows how the government turned discourses of public interest and public obligation into modern land laws.
Acanthocephalans are parasites with complex lifecycles that are important components of aquatic systems and are often model species for parasite-mediated host manipulation. Genetic characterization has recently resurrected Pomphorhynchus tereticollis as a distinct species from Pomphorhynchus laevis, with potential implications for fisheries management and host manipulation research. Morphological and molecular examinations of parasites from 7 English rivers across 9 fish species revealed that P. tereticollis was the only Pomphorhynchus parasite present in Britain, rather than P. laevis as previously recorded. Molecular analyses included two non-overlapping regions of the mitochondrial gene – cytochrome oxidase and generated 62 sequences for the shorter fragment (295 bp) and 74 for the larger fragment (583 bp). These were combined with 61 and 13 sequences respectively, from Genbank. A phylogenetic analysis using the two genetic regions and all the DNA sequences available for P. tereticollis identified two distinct genetic lineages in Britain. One lineage, possibly associated with cold water tolerant fish, potentially spread to the northern parts of Britain from the Baltic region via a northern route across the estuarine area of what is now the North Sea during the last Glaciation. The other lineage, associated with temperate freshwater fish, may have arrived later via the Rhine/Thames fluvial connection during the last glaciation or early Holocene when sea levels were low. These results raise important questions on this generalist parasite and its variously environmentally adapted hosts, and especially in relation to the consequences for parasite vicariance.
OBJECTIVES/GOALS: Our lab previously identified a population of vascular smooth muscle (SMC)-derived progenitor cells (AdvSca1-SM) which expand robustly in response to disease and can differentiate into multiple cell types. We now aim to define the role of these AdvSca1-SM cells in atherosclerotic plaque progression. METHODS/STUDY POPULATION: Goal one uses SMC lineage tracing mice and a model of atherosclerosis to track reprogramming of SMCs to AdvSca1-SM cells in the setting of disease. Arteries are analyzed using flow cytometry and immunofluorescence to quantify changes in number of mature SMCs and AdvSca1-SM cells. Goal two uses AdvSca1-SM lineage tracing mice with high cholesterol-induced atherosclerosis and plaque neovascularization. Arteries are analyzed to quantify expansion of AdvSca1-SM cells, subsequent re-differentiation into mature SMC, endothelial cells, or macrophages, and contribution to plaque neovascularization. Mechanistic findings from both goals are being investigated in diseased human coronary arteries. RESULTS/ANTICIPATED RESULTS: Flow cytometry from SMC lineage tracing mice revealed a 7- to 13-fold expansion of AdvSca1-SM cells in carotid arteries (p<0.001) and aortas (p = 0.03) after 6 weeks of western diet; no differences in macrophage numbers were observed. Additional SMC and AdvSca1-SM cell lineage tracing mice are on atherogenic diets to assess early and advanced atherosclerosis. We predict that AdvSca1-SM cells will contribute to macrophage accumulation as well as plaque neovascularization in the setting of severe atherosclerosis. Translational relevance of mechanisms driving SMC reprogramming and AdvSca1-SM cell contribution to plaque progression are being applied to studies of diseased human coronary arteries. DISCUSSION/SIGNIFICANCE OF IMPACT: Our data suggest a role for AdvSca1-SM cells in atherosclerosis. Ongoing work will clarify the mechanisms driving plaque-associated AdvSca1-SM expansion and define the ultimate fates of these cells. In vivo modulation of this process could provide the basis for future anti-atherosclerotic therapies.

There have been conflicting reports on the relationship between thyroid function and mood between studies in subjects on thyroxine and the general population not on thyroxine. We investigated this relationship in a large population study.
We analysed data on serum TSH levels and Hospital Anxiety and Depression Scale (HADS) scores from the HUNT 2 study (age ≥ 40 years). Following a test for interaction, analyses were performed separately in females on thyroxine (n=1,265) and in people not on thyroxine (males n=9,319 and females n=17,694).
More females on thyroxine had high depression and anxiety scores than females not on thyroxine (depression 18.4% vs 13.0%, p< 0.001, anxiety 23.4% vs 18.7% p< 0.001). In those not on thyroxine there was an inverse association between serum TSH and depression score in males (B coefficient = -0.61, 95% CI -0.91 to -0.24, p=0.001) though not in females (B coefficient = -0.07, -0.33 to 0.19), and an inverse association between TSH and anxiety score in both sexes (B coefficient for males = -0.68, 95% CI -1.04 to -0.32, p< 0.001; females -0.37, -0.67 to -0.08, p=0.01). By contrast, in females on thyroxine, TSH was positively associated with both depression (B coefficient = +0.27, 95% CI 0.02 to 0.51, p< 0.05) and anxiety (B coefficient = +0.29, 0.01 to 0.56, p< 0.05).
There is a different relationship between thyroid function and depression and anxiety in females on thyroxine compared to individuals with no thyroid disease.
There are no large scale studies on Epilepsy in populations with Learning disability in Ireland. As many as one fifth of these clients have epilepsy. Aggressive treatment may lead to diminishing returns in terms of symptomatic control, while causing unwanted effects.
1. We aimed to quantify rates of epilepsy, aetiology and anti- epileptic drug (AED) use in our population.
2. To look at degree of disability and correlation with AED use.
3. To look at management/ quality of life issues using a validated instrument.
1. Medline review using search terms Intellectual OR Learning difficult* OR Mental Retard* AND Epilepsy.
2. Simple questionnaire used to identify all clients with Epilepsy. Database analysed using SPSS analysis.
3. 11 cases selected for review looking at qualitative aspects, using Semi structured interview and GEOS scale.
· 210 patients found to have a history of epilepsy (42% of clients).
· Multiple Aetiologies identified. Commonest known Aetiology: Trisomy 21.
· Polypharmacy is common. Most commonly used AED: Sodium Valproate. Mean AED use: 1.595 (SD+- 1.077).
· Clients with Trisomy 21 aged less than 40 tended to be on more medication (2.05, SD= +-1.38) than those over 40 years (1.43, SD= +- 0.89)
· Greater concerns on qualitative measures regarding clients with refractory epilepsy or where epilepsy changed over time.
Our study highlights previously recognised changing patterns in aetiology of Learning Disability and also the changes over time in these clients. More study is required.
There is a growing appreciation that depression may be a presenting syndrome of dementia.
This study intends to show that the presence of cognitive impairment in a depressive episode in older people may have important prognostic implications in developing dementia.
In this study a first group of 17 depressed patients with mild cognitive impairment (MMSE over 26) was compared with a second group of 18 depressed patients with mild to moderate cognitive impairment (MMSE bellow 26). The mean age for both groups was 68. The depression was measured using the MADRS scale. All the patients included were severely depressed at the inclusion. Both groups showed important improvement of the depressive episode, following the treatment with antidepressants (escitalopramum, sertralinum, venlafaxinum).
Both groups were followed for 2 years after the depression resolution.
In the first group of patients the MMSE was 26 at baseline and 26 or over at discharge.
In the second group of patients the score of MMSE had a value of minimum 17 at baseline and a maximum of 26 at discharge.
Five patients (three in the first group and two into second group) did not complete the 2 years follow up period.
Over the period of 2 years, 37% of patients from the second group developed a dementia, comparing with only 14% of the patients from the first group.
After 2 years, the patients with depression and significant cognitive impairment had twice the risk of developing dementia as those who had only depression.
We investigated the contribution of polymorphisms shown to moderate transcription of serotonin transporter (5HTT) and monoamine oxidase A (MAOA) to the development of violence, and furthermore to test for gene x environment interactions. To do so, a cohort of 184 adult male volunteers referred for forensic assessment were assigned to a violent or non-violent group. 45% of violent, but only 30% of non-violent individuals carried the low-activity, short MAOA allele. In the violent group, carriers of low-function variants of 5HTT were found in 77%, as compared to 59%. Logistic regression was performed and the best fitting model revealed a significant, independent effect of childhood environment and MAOA genotype. A significant influence of an interaction between childhood environment and 5HTT genotype was found (Fig. 1). MAOA thus appears to be independently associated with violent crime, while there is a relevant 5HTT x environment interaction.
Low and middle-income countries experience an expressive growth in the number of circulating motorcycles, paralleled by an increasing number of traffic accidents. Delivery motorcycles drivers (“motoboys”) are generally perceived as accountable for this scenario. Although traffic accidents have a multivariate etiology, mental disorders, such as substance use disorders (SUD) and attention deficit/hyperactivity disorder (ADHD), are often involved. This paper aims at investigating the prevalence of ADHD, SUD and other mental disorders in a sample of Brazilian motoboys, and additionally, to evaluate the association between psychiatric diagnoses, motorcycle accidents and traffic violation tickets.
A convenient sample of subjects was invited to participate in a cross-sectional assessment including an inventory of traffic accidents and violations. Psychiatric diagnoses were based on semi-structured and clinical interviews.
A sample of 101 motoboys was assessed. Overall, 75% of subjects had a positive lifetime history of at least one psychiatric disorder. SUD was the most frequent diagnosis (43.6% for alcohol, 39.6% for cannabis). ADHD was associated with a higher number of traffic accidents (p = 0.002), and antisocial personality disorder (APD) was associated with a greater number of traffic violations (p = 0.007).
The prevalence of mental disorders was much higher in our sample than in the general population. ADHD and APD, but not SUD, were associated with negative traffic outcomes. These findings have implications for public mental health planning since mental disorders can be both prevented and treated, improving driving behavior and increasing road safety.
Patients with bipolar disorder are at risk of obesity, metabolic syndrome and diabetes mellitus. Little was known about the association of clinical characteristics of bipolar disorder and diabetes mellitus.
Investigate the clinical characteristics of patients with bipolar disorder and diabetes mellitus.
Identify the risk factors of medical comorbidity.
Patients suffering from bipolar disorder, according to DSM-IV classification, with and without diabetes mellitus were retrieved from computer database in a university teaching hospital psychiatric outpatient clinic. Patients with diabetes mellitus were compared with patients without diabetes mellitus after matching with sex and age.
One hundred and fifty patients with bipolar disorder (30 with diabetes mellitus and 120 without diabetes mellitus) were collected. All patients were Chinese and 86.7% were female. For patients with and without diabetes mellitus, the mean (SD) age were 49.9 (9.3) years and 49.4 (8.9) years respectively. Their mean (SD) duration of mental illness were 18.1 (10.9) years and 16.8 (10.6) years and the mean number of admissions were 3.4 (4.2) and 3.2 (4.3) for patients with and without diabetes mellitus respectively. The use of antipsychotics and mood stabilizer were similar between patients with and without diabetes mellitus. Hypertension and dyslipidemia were statistically significant factors associated with diabetes mellitus among patients with bipolar disorder.
Hypertension and dyslipidemia are associated with diabetes mellitus among Chinese patients with bipolar disorder. Psychiatrists should be alerted to screen and monitor for hypertension, dyslipidemia and diabetes mellitus among patients with bipolar disorder.
Receiving and understanding the psychological and sociocultural aspects associated to both health problems and difficulties to make the eating behaviour changes are relevant issues when treating individuals with Metabolic Syndrome.
Objective and aims
The reports given by chronic individuals in the present study allowed for analyzing the subjective expressions related to food, treatment management and patient adherence to self care propositions.
In-depth semi-directed interviews with open-ended questions, with psychodynamic orientation in the conducting dialogues were performed with nine patients from the endocrinology outpatient service of a public university hospital located in Southeast Brazil. From this broader objective, a selection was made of some experiences reported by the subjects, which were related to the process of managing treatment and eating behaviour, implied in chronic metabolic disorders.
In this work, elements that mediate the process of developing autonomy in eating habits, living with the illnesses and vulnerability factors experiences by Metabolic Syndrome patients are identified in this study.
The interdisciplinary character of the present study promoted the valorisation of the practice of listening to the psychological and cultural meanings of eating behaviours, hence offering contributions regarding the nutritional care of individuals with Metabolic Syndrome.
This investigation's main goal was to determine if some psychosocial (self-concept, control locus, assertiveness and satisfaction towards social support) and cognitive variables (health beliefs and attitudes towards health) were associated to health related behaviours. The sample was constituted by 829 teenagers, 382 male and 447 female, whose average age is 14.66 years old, who attended the 9th grade of the public and daily schools in the district of Viseu, Portugal.
1.Study on the association between health and risk behaviours and psychosocial variables: The better the self-concept, the better the behaviours; The higher the satisfaction with social support, the better the behaviours; The higher the assertiveness, the better the behaviours; The association between control locus and healthy and risk behaviours is not significant.
2.Study on the association between health and risk behaviours and cognitive variables: The more favourable the attitudes towards health, the better the behaviours; The more adequate the health beliefs, the better the behaviours.
3.Study on the psychosocial variables interaction effects with cognitive variables in health and risk behaviour prediction: The interaction variable was revealed as the best health and risk behaviour predictor is the variable resulting from Factor 1 - behavioural aspect (Self-Concept) and Factor 4 - preventive attitude (Attitudes Towards Health) interaction, with a determination coefficient (R2) of .409. The patterned coefficient analysis Beta (beta=.427) indicates that the higher this interaction effect (F1 - behavioural aspect * F4 - preventive attitude) the better the behaviours.
It is a consummate fact that the youths occupy, during the adolescence most of the day in the school, being that many prominent behaviours for the health are initiated in this phase of the life. It is for that fundamental that the schools be health promoters spaces.Objectives : to know the age of initiation to the consumption of alcoholic beverages, tobacco and illicit drugs in this sample; to calculate the prevalence rate of these consumption; to identify priority areas to approach in the Health Education process.
This is a descriptive and cross-sectional study, that is going to identify behaviours of risk for the health of High School students of Douro Region. The sample is constituted by 466 students of seven schools. The data were collected through a questionnaire on line, of Janeiro to March of 2007, disposed in the site http://jovemsaudavel.com.sapo.pt, designed for the effect. In the data treatment we utilize the statistical descriptive and the qui-square test.
The ages average of initiation to the consumption of alcoholic beverages, tobacco and illicit drugs is 12,5, 12,3 and 13,6 years, whereas the prevalence's of these consumption are 38,9%, 16,9% and 6,0%, respectively. Highlights-itself the sporadic consumption of alcoholic beverages (28,4%), the abusive consumption of tobacco (9,4%) and of illicit drugs (1,8%). The boys swallow beverages and smoke with bigger frequency than the girls ((c2: p = 0,006 and 0,001). They had intercourse relations already 27,7% of the students of this sample, of the which 11,9% did not use protection.
The increasing prevalence of concurrent eating and substance use disorders has been well documented in both the eating disorders and in substance use disorders literature. Despite evidence for the important role of families and wider social networks in addiction and eating disorder treatment, concurrent eating and substance use disorder therapy has focused on treating the concurrent disorders, and largely overlooked the needs of families. This study explores the impact of concurrent eating and substance use disorders on family members to identify the family's needs in order to direct future intervention.
A series of semi-structured interviews were completed with family members of patients with concurrent eating and substance use disorders. A qualitative grounded theory approach was used to analyze the data and involved the coding of transcripts and the development of emerging themes.
Three major themes emerged from the analyses: 1) Families’ inability to cope; 2) Inadequate communication and involvement of family in therapy; 3) Lack of information about the disorders themselves.
Data suggest that greater emphasis in service provision must be placed on family members and wider social networks to: 1) help assist clients to engage and stay in treatment; 2) improve both disorder outcomes and family functioning, and 3) reduce impacts and harm for family members and others affected. Suggestions for helping clinicians and new avenues for service provision and research are presented.
Explore the prevalence of lifetime suicide attempts in women with bulimia nervosa (BN), and compare eating disorder symptoms, general psychopathology, impulsivity, personality, and genetic variants in four candidate genes of the serotonin pathway: the serotonin transporter (SLC6A4), serotonin receptors 1A (HTR1A) and 2A (HTR2A) and tryptophan hydroxylase 1 (TPH1) between individuals who had and had not attempted suicide. Determine the best predictors of suicide attempts.
Lifetime prevalence of suicide attempts was 26.9% CI 95%: 23.2 to 30.5). BN subtype was not associated with lifetime suicide attempts (p=0.36). Compared to non-attempters, attempters exhibited higher unemployment, eating disorder symptomatology, general psychopathology, previous eating disorder treatment, impulsive behaviors, and lower educational level (p<0.004). In relation to personality traits, suicide attempters exhibited significantly (p<0.002) higher Harm Avoidance and lower Self-directedness, Reward Dependence and Cooperativeness. No significant differences in any of the genetic variants between attempters and non-attempters. The best predictors of suicide attempts were (p<0.006): lower education, minimum BMI, previous eating disorder treatment, family history of alcoholism and self-directedness.
Suicidality in BN patients appears to be within the range previously found. Our results support that internalizing personality traits combined with impulsivity may increase the probability of engaging in suicidal behaviors in these patients. Our data do not support the hypothesis that variants of SLC6A4, HTR1A, HTR2A or TPH1 are associated with suicide attempts in BN individuals.
The diagnostic frontiers of social anxiety disorder (SAD) are still controversial, since it could be described as part of a continuum of severity rather than as a disorder based on an arbitrary threshold with qualitative distinctions. The present study aims to investigate possible differences among subjects along the social anxiety spectrum using the Simulated Public Speaking Test (SPST), an experimental model of human anxiety. Afterwards, the anticipatory measures of SPST among groups were correlated with different volume of gray matter areas by MRI using the voxel-based morphometry method.
We evaluated patients with generalized SAD (n=25), subjects with subclinical SAD (with fear of a social situation without avoidance or impairment; n=14) and healthy controls (n=22).
The subjective SPST findings showed that avoidance and functioning impairment were due to a negative self-evaluation in SPST and not to the level of anxiety experienced. When all groups were pooled together, there was a positive correlation between levels of anxiety experienced and the volume of the right amygdala. The negative self-evaluation of performance in the SPST was associated with a reduction in the volume of the anterior cingulated complex (ACC) only in the SAD group.
These results suggest that the association between anxiety and amygdala volume may be a part of a continuum of social anxiety. However, the correlation between self-evaluation of performance with reduced ACC volume only in the SAD group does not support the idea that this association may be also part of a continuum.
There is growing body of evidence that support an association between stressful life events (SLEs) and an increase risk for Multiple Sclerosis (MS) exacerbations. The aims of this study were: first, to examine the relationship between SLEs and MS exacerbations; second, to investigate how SLEs frequency influence MS disease activity.
Twenty six ambulating women (Expanded Disability Status Score, EDSS ≤3) with relapsing-remitting Multiple Sclerosis were followed-up for one year or more. Patients documented SLEs weekly in self report diaries which were then collected at regular clinic visits every 4 weeks. Neurological examination was performed, at baseline and at every regular and additional visit after a suspect exacerbation.
A Cox univariate regression analysis showed that 1 or 2 SLEs had no effect on risk for relapses. In the opposite 3 and ≥ 4 SLEs were associated with 5.3 (95% CI 1.7 to 16.4, p=0.003) and 16.7 (95% CI 4.6 to 60.5, p<0.001) times respectively the rate of relapsing during the following four weeks. The number of the reported SLEs was not correlated with the EDSS score [r(26)=-0.10, p>0.05], the system involved [r(26)=0.01, p>0.05], or the duration of the relapse [r(26)=0.02, p>0.05].
This data provide prospective evidence that SLEs may trigger MS exacerbations. The effect of stress on relapse risk in MS is cumulative. A higher density of stress is not related with a mayor inflammation process.
During gestation and maternal behavior, some physiological events can protect the dam and offspring, but explanations for such phenomena are partially unknown. The effects of stress during prenatal development and infancy can be studied in controlled laboratory conditions.
To determine the pre- and postnatal effects of stress on coping strategies in weanling rats subjected to the open field and forced swim tests after their dams are subjected to stress during gestation.
Rats aged 21 postnatal days (PND) were assigned to either a Control group (n = 36; offspring from intact dams during gestation) or a Prenatal stress group (n = 36; offspring from dams forced to swim during 5 min sessions on gestational days 1, 7, 14, and 19). Both groups were tested in the open field to evaluate locomotor activity and rearing. In another experiment, PND21 intact rats assigned to a Control group (n = 26) or Postnatal stress group (n = 35) were subjected to restraint stress for 6 min prior to the tests and were later evaluated in the forced swim test.
Locomotor activity (p < 0.026) and rearing (p < 0.001) were lower in the Prenatal stress group compared with the Control group. The latency to first immobility was shorter (p < 0.008), and the total immobility time was longer (p < 0.005) in the Postnatal stress group than Control group.
Stress exposure during gestation produces detectable changes during weanling, consisting of reduced exploratory activity and susceptibility to despair.
