Untangling the links of parental responsiveness to distress and warmth to child outcomes.

This study demonstrated separate linkages between 2 features of positive parenting--responsiveness to distress and warmth--and different aspects of children's socio-emotional functioning, in a sample of 106 children (6-8 years old). As expected, mothers' and fathers' responsiveness to distress, but not warmth, predicted better negative affect regulation. Maternal responsiveness to distress also predicted children's empathy and prosocial responding. Maternal warmth, but not responsiveness to distress, was linked to better regulation of positive affect and (in boys only) to greater peer acceptance. Additionally, negative affect regulation mediated between maternal responsiveness to distress and children's empathic responding. Positive affect regulation mediated between maternal warmth and boys' peer acceptance. The findings support a differentiated approach to positive parenting.

In the eye of the beholder: social and personal characteristics of teenagers and their impressions of themselves and fat and slim people.

Fifty-nine female and 79 male secondary students rated six stimulus figures (self, ideal self, fat young man/woman, slim young man/woman) on 28 personal rating scales. They also complete the Eysenck personality Inventory. Each of the stimulus-figure data sets was factor analysed and the factor scores were related to role, personality, and perceived weight status by means of correlational and discriminant function analyses. The results showed that the perceives' sex, ethnicity and perceived weight status were related to their perception of the stimulus figures. These relationships included interactions between sex and ethnicity in their effects on reported views of ideal self and fat young woman (FYW). Daughters of European migrants reported more independent and stronger self-aspiration than did their peers, and sons of European migrants saw FYW mor positively that did the other subjects. The observed relationship between females' perceived weight status and their self-concepts suggest that body image may be of greater importance for girls that for boys of this age. Extraversion and neuroticism differed according to sex in their relationships with the subjects' perceptions of the FYW figure. These and other findings indicate that the presence or absence of obesity has relevance for social and psychological processes as well as for medical issues.

Assessing systems properties of yeast mitochondria through an interaction map of the organelle.

Mitochondria carry out specialized functions; compartmentalized, yet integrated into the metabolic and signaling processes of the cell. Although many mitochondrial proteins have been identified, understanding their functional interrelationships has been a challenge. Here we construct a comprehensive network of the mitochondrial system. We integrated genome-wide datasets to generate an accurate and inclusive mitochondrial parts list. Together with benchmarked measures of protein interactions, a network of mitochondria was constructed in their cellular context, including extra-mitochondrial proteins. This network also integrates data from different organisms to expand the known mitochondrial biology beyond the information in the existing databases. Our network brings together annotated and predicted functions into a single framework. This enabled, for the entire system, a survey of mutant phenotypes, gene regulation, evolution, and disease susceptibility. Furthermore, we experimentally validated the localization of several candidate proteins and derived novel functional contexts for hundreds of uncharacterized proteins. Our network thus advances the understanding of the mitochondrial system in yeast and identifies properties of genes underlying human mitochondrial disorders.

Assisted survival, aging, and rehabilitation needs: comparison of older dialysis patients and age-matched peers.

In Western societies a growing number of older persons have their lives extended by medical or surgical intervention. Older persons who suffer kidney failure and are maintained by chronic dialysis therapy are a good example. We compared 349 persons aged 60 years or older, who were on chronic dialysis, with 354 persons similar in age, race, gender, and geographic residence who were not undergoing dialysis. Recent health problems and demographic characteristics were included as control variables in all analyses. Older persons on dialysis reported more functional disability (as measured by ADL-mobility difficulty), less frequent walking for exercise, decreased ability to do the things they would like to do, and lower levels of perceived mastery over their lives. They were also more likely to report a need for health-related aids or services. The residual impairments of disabled elderly persons challenge rehabilitation professionals to address quality of life issues.

Tic-related school problems: impact on functioning, accommodations, and interventions.

Children with Tourette's syndrome (TS) are statistically overrepresented in special education classes; however, the extent to which tics contribute to such placement is unclear. In this article, the results of a survey of parents or guardians of 71 children and adolescents with TS are described within the broader context of discussing the impact of tics and educational practices. One half of the respondents reported moderate to significant tic-related academic impact, and 48% reported moderate to significant tic-related peer problems. Peer education and in-school counseling were generally not offered nor provided. In the minority of cases where behavioral interventions for tics were reported, contingent aversive consequences were reported to be ineffective or counterproductive, while positive reinforcement for modifying tics reportedly produced some successful results. The identification of research-validated academic accommodations and increased involvement of school psychologists are suggested as necessary and potentially helpful supports for students with TS and their teachers.

Psychosocial functioning of severely disturbed adolescents after short-term hospitalization.

Forty-two severely emotionally disturbed adolescents discharged after a brief hospitalization for an acute psychiatric episode were assigned to two groups--one for whom clinicians recommended continued intensive treatment in an inpatient, residential, or day treatment setting, even though such services were not available, and the other for whom clinicians recommended only outpatient treatment. The two groups were compared on rates of rehospitalization, self-harmful actions, and suicide attempts and on severity of problems with peers during the six months after discharge. The two groups showed significant differences only in the extent of their problems with peers.

Development and preliminary validation of a semi-structured interview for the screening of law enforcement candidates.

A standard practice among most law enforcement agencies is to include psychological screening in the selection of job candidates. Although the use of personality tests in predicting job performance of law enforcement officers has received empirical support (e.g., the Minnesota Multiphasic Personality Inventory, the Inwald Personality Inventory), there is a conspicuous absence of data regarding the reliability and validity of interview procedures. The present study represents the first step in the development of a standardized, semi-structured interview for use in the screening of law enforcement personnel. This interview, the Law Enforcement Candidate Interview, was constructed using content areas drawn from measures used in the screening of law enforcement personnel (e.g., Inwald Personality Inventory) and assessment of personality functioning (Structured Clinical Interview for DSM-III-R Personality Disorders). This interview was then administered by two doctoral students to a group of law enforcement academy cadets (n=34). A modest degree of inter-rater reliability was achieved, although internal consistency was somewhat lacking. Interview scores were correlated with measures of academy performance (final grade-point average and peer and supervisor ranking of academy performance). Results of these analyses suggest the LECI is a modest predictor of academy performance. Potential uses of the LECI and future research indications are outlined.

Disinhibitory psychopathology in male adolescents: discriminating conduct disorder from attention-deficit/hyperactivity disorder through concurrent assessment of multiple autonomic states.

T. P. Beauchaine recently proposed a model of autonomic nervous system functioning that predicts divergent patterns of psychophysiological responding across disorders of disinhibition. This model was tested by comparing groups of male adolescents with attention-deficit/hyperactivity disorder (ADHD) and attention-deficit/hyperactivity disorder plus conduct disorder (CD/ADHD) with controls while performing a repetitive motor task in which rewards were administered and removed across trials. Participants then watched a videotaped peer conflict. Electrodermal responding (EDR), cardiac pre-ejection period (PEP), and respiratory sinus arrhythmia (RSA) were monitored. Compared with controls, the ADHD and CD/ADHD participants exhibited reduced EDR. The CD/ADHD group was differentiated from the ADHD and control groups on PEP and from the control group on RSA. Findings are discussed in terms of the motivational and regulational systems indexed. Implications for understanding rates of comorbidity between CD and ADHD are considered.

Social dimensions of adolescent substance use.

OBJECTIVES: The aim of this study was to explore in detail the relationship between various social aspects of young people's lives and substance use and differences in the degree of influence exerted by the different social factors as a function of age. Design, setting, participants. The study was a survey of pupils aged 11-16 in a stratified sample of five English schools. Data from 4516 participants were obtained in relation to their cigarette, alcohol and illicit drug use and their contact with the police, perceived academic achievements and future expectations, religious beliefs, family structure, the importance of family versus peer opinions and suspension from school. MEASURES: Cumulative, age-specific preferences of substance misuse were compared. Logistic regression was used to rank the various risk factors. RESULTS: Substantial differences were found between substance users and non-users and the various risk factors being examined. For example, of those who had only been in trouble with the police, 18.8% used illegal drugs compared with 1.6% of those who had not had a police contact and who had no other risk factors. Many of these relationships were age-sensitive. For instance, the negative relationship between belief in God and illicit drug use became stronger as age increased (non-believers: y = 8.1886x - 9.16 R(2) = 0.9484; believers: y = 5.1514x - 8.08 R(2) = 0.9247). These results suggest that, within this sample of English adolescents, there was a strong relationship between substance use and the social factors examined. Although there were differences depending upon whether cigarette, alcohol or illicit drug use was being modelled, logistic regression indicated that the social factors could be ranked in the following order of importance: concurrent use of the second and third substances, having been in trouble with the police, perceived poor academic performance and low future academic expectations, a lack of religious belief, coming from a non-intact family, favouring peer over family opinion and having been suspended from school. Many of these relationships were age-sensitive with substance use peaking at age 15. CONCLUSION: The models and relationships presented in this paper show that a constellation of behaviours are related to adolescent substance use. Also demonstrated is that behaviours cannot be considered in isolation, but need to be examined from an holistic or biopsychosocial standpoint. These relationships are complex and future research should consider not only causality of adolescent substance use, but also of the aetiology of the satellite behaviours.

Toward an integrated approach to molecular epidemiology.

The emergence of "molecular epidemiology" as a scientific approach within the fields of epidemiology and toxicology has led to spirited discussion within the biomedical community, particularly in the area of cancer research. At scientific meetings and in peer-reviewed journals, numerous issues have been raised not only with regard to the practice of molecular epidemiology, but also with regard to its role in traditional epidemiology, toxicology, and risk assessment. Furthermore, the utility of information gleaned from such studies and the implications for public health have been the subject of considerable debate. Conceptual differences in how one views the function of epidemiologic and laboratory research may be reflected in discussions on the merits of molecular epidemiology. This commentary reviews some of the prevailing attitudes toward molecular epidemiology, with the goal of identifying areas of concern and suggesting means of achieving harmonization. The need for cross-training of epidemiologists and laboratory scientists is discussed, and suggestions are made for building successful collaborative relations across disciplines.

Active and passive mobility of lower limb joints in elderly men and women.

An age associated decline in joint mobility during the early and middle adult years is well documented, however, little information exists on the progress of this aspect of joint function during old age. Active and passive ranges of 10 lower limb joint motions were measured in 80 healthy, active men and women aged from 70 years, to examine the relationship between the capacity for joint movement and age, gender, and type of motion. Joint mobility declined consistently as age increased, with women generally having greater movement capability than their male peers. The predominant trend was for a more rapid reduction in mobility during the ninth decade. Passive ranges were larger than those produced actively, and the pattern of change in both measurement modes was parallel over the age range. It is hypothesized that the consistent decline in mobility indicates the importance of biological aging of articular structures as a primary cause of increasing resistance to movement, while environmental causes, such as changing activity status, are suggested by the variation in the magnitude and patterns of change over the age range.

Impact of sexual abuse on the HIV-risk-related behavior of adolescents in intensive psychiatric treatment.

OBJECTIVE: This study compared the HIV-risk-related behaviors and attitudes of adolescents with and without a history of sexual abuse who were in intensive psychiatric treatment. METHOD: Adolescent patients (N=208) completed measures of psychological functioning and HIV-related knowledge, attitudes, and behaviors. RESULTS: Among sexually active adolescents in psychiatric treatment (N=116), those with a history of abuse reported significantly less condom self-efficacy (emotional ability to use condoms), less knowledge of HIV, less impulse control, less frequent use and purchase of condoms, and significantly higher rates of sexually transmitted diseases than their peers. Multiple logistic regression indicated that a history of sexual abuse was strongly associated with inconsistent condom use. CONCLUSIONS: Sexual abuse was associated with HIV-risk-related attitudes and behaviors among adolescents in psychiatric treatment. Clinicians should thus view a history of sexual abuse as a marker for sexual behavior that puts adolescents at risk for HIV.

Bipolar I disorder: psychopathology, medical management and dental implications.

BACKGROUND: The authors review the clinical features, epidemiology, pathophysiology, medical management, dental findings and dental management of patients who have bipolar I disorder, or BD, previously known as manic-depressive disorder. TYPES OF STUDIES REVIEWED: The authors conducted a MEDLINE search for the period 1995 through 2001 using the key terms "bipolar disorder," "epidemiology," "pathophysiology," "treatment" and "dentistry." The articles they selected for further review included those published in English in peer-reviewed journals; they gave preference to articles reporting randomized, controlled trials. RESULTS: BD is a psychiatric illness characterized by extreme mood swings. Mania is accompanied by euphoria, grandiosity, racing thoughts and lack of insight. Depression is characterized by marked sadness or loss of interest or pleasure in daily activities. The unpredictable mood swings can distress the person, can impair social function and quality of life and are associated with a significant increase in the risk for substance abuse and suicide. BD is common in the United States, with a lifetime prevalence rate of 1.6 percent and recurrence rate of more than 50 percent. CLINICAL IMPLICATIONS: The prevalence of dental disease usually is extensive because of poor oral hygiene and medication-induced xerostomia. Preventive dental education, saliva substitutes and anticaries agents are indicated. To avoid adverse drug interactions with the usually prescribed psychiatric medications, special precautions should be taken when administering certain antibiotics, analgesics and sedatives.

Diagnosis and nonoperative management of cervical radiculopathy.

STUDY DESIGN: Qualitative, comprehensive literature review. OBJECTIVE: To discuss and summarize the current peer-reviewed literature related to the management of patients with cervical radiculopathy. BACKGROUND: Cervical radiculopathy is a lesion of the cervical spinal nerve root with a reported prevalence of 3.3 cases per 1000 people; peak annual incidence is 2.1 cases per 1000 and occurs in the fourth and fifth decades of life. Nerve root injury has the potential to produce significant functional limitations and disability. METHODS AND MEASURES: A search of the MEDLINE, CINAHL, and Web of Science databases for the periods 1966, 1982, and 1996, respectively, to December 1999 was conducted using selected keywords and MeSH headings. The bibliography of all retrieved articles were searched and pertinent articles were obtained. The Cochrane Database of Systematic Reviews was also searched. Literature related to the diagnosis, prognosis, and treatment of cervical radiculopathy were thoroughly reviewed and summarized using a critical appraisal approach. RESULTS: Although cervical radiculopathy remains largely a clinical diagnosis, the true diagnostic accuracy of the clinical examination for cervical radiculopathy is unknown. Imaging and electrophysiologic tests are capable of detecting clinically significant problems in many patients and each modality has inherent strengths and weaknesses; technical as well as practical factors affect the choice of procedure. The natural course of cervical radiculopathy appears to be generally favorable but no prognostic or risk factors have been firmly established and the efficacy of various nonoperative treatments for the condition is unknown. CONCLUSION: A clear definition of terms and further research are required to establish definitive diagnostic criteria and effective treatment for the management of patients with cervical radiculopathy.

DIACOM: a collective learning forum for continuing medical education.

DIACOM forum (Case based Interactive discussions for Medical education) is a computing tool dedicated to physicians in continuing education. Its goal is learning based on a distant clinical case confrontation between peers. Each learner can describe a case from his or her own experience, and the underlying system puts authors in touch whose cases have common points of interest. Research works managed in the SaSo Laboratory aims at developing a DIACOM from prototype for Continuing Medical Education (CME) in pediatric pain management. This paper presents the theoretical and pedagogic context and the functioning of the DIACOM forum.

[Self-image of female adolescents suffering from anorexia nervosa].

AIM: The paper presents results of research concerning the differences in some aspects of self-image between female adolescents with anorexia nervosa (who meet criteria of DSM-IV) and their healthy peers. METHOD: Each group consisted of 30 individuals. They completed the Offer Self-Image Questionnaire for Adolescents (OSIQ). It is a self-descriptive personality test that can be used for measuring the adjustment of adolescents between the ages of thirteen and nineteen. RESULTS: The study revealed some interesting differences between groups. They refer mainly to emotional aspects of their functioning. CONCLUSIONS: The basic conclusion is that self-image of anorectic girls is much more disturbed than of the healthy girls. Significant differences are presented and discussed according to the literature.

Information, discrimination and divergence in cytology. I. Theoretical aspects and definitions.

The results of medical tests update the probability of diagnosis (diagnosability) of a patient from the population prevalence of a disease. This paper demonstrates a method of combining several mutually dependent tests as the sum of log odds ratios, and of separating the log odd ratios of the test results and those of prevalences. Extending Kullback's discriminant function between two states to m states (m greater than or equal to 2), it is shown that the information of a test can be measured by discrimination and divergence, which are well-defined measures in information theory and test theory. The performance of diagnostic cytology can then be compared to the results of histopathologic diagnoses or to a peer-reviewed consensus without the use of arbitrarily given scores or without unfounded assumptions about underlying continuous variables. They can also provide a way to optimize the categorization (classification) of Papanicolaou smears and a means of quality control for morphologic tests. These methods can be used to evaluate the performances of cytology laboratories that use two classifications consisting of different numbers of categories (classes) and states.

Post-traumatic stress disorder in the military veteran.

1. Military personnel exposed to war-zone trauma are at risk for developing PTSD. Those at greatest risk are those exposed to the highest levels of war-zone stress, those wounded in action, those incarcerated as prisoners of war, and those who manifest acute war-zone reactions, such as CSR. 2. In addition to problems directly attributable to PTSD symptoms per se, individuals with this disorder frequently suffer from other comorbid psychiatric disorders, such as depression, other anxiety disorders, and alcohol or substance abuse/dependence. The resulting constellation of psychiatric symptoms frequently impairs marital, vocational, and social function. 3. The likelihood of developing chronic PTSD depends on premilitary and postmilitary factors in addition to features of the trauma itself. Premilitary factors include negative environmental factors in childhood, economic deprivation, family psychiatric history, age of entry into the military, premilitary educational attainment, and personality characteristics. Postmilitary factors include social support and the veteran's coping skills. 4. Among American military personnel, there are three populations at risk for unique problems that may amplify the psychological impact of war-zone stress. They are women whose war-zone experiences may be complicated by sexual assault and harassment; nonwhite ethnic minority individuals whose premilitary, postmilitary, and military experience is affected by the many manifestations of racism; and those with war-related physical disabilities, whose PTSD and medical problems often exacerbate each other. 5. The longitudinal course of PTSD is quite variable. Some trauma survivors may achieve complete recovery, whereas others may develop a persistent mental disorder in which they are severely and chronically incapacitated. Other patterns include delayed, chronic, and intermittent PTSD. 6. Theoretically primary preventive measures might include prevention of war or screening out vulnerable military recruits. In practice, primary preventive measures have included psychoeducational and inoculation approaches. Secondary prevention has been attempted through critical incident stress debriefing administered according to the principles of proximity, immediacy, expectancy, and simplicity. Tertiary prevention has included psychotherapy, pharmacotherapy, dual diagnosis approaches, peer counseling, and inpatient treatment. Few treatments have been rigorously evaluated. 7. There are both theoretical reasons and empirical findings to suggest that military veterans with PTSD are at greater risk for more physical health problems, poorer health status, and more medical service usage. Much more research is needed on this matter. 8. Despite the potential adverse impact of war-zone exposure on mental and physical health, there is also evidence that trauma can sometimes have salutary effects on personality and overall function.
