Clinical safety of drug-eluting stents in the Korea acute myocardial infarction registry.

BACKGROUND: Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) may be useful in patients with acute myocardial infarction (AMI), but safety issues still need to be solved. This study was undertaken to investigate the incidence of major adverse cardiac events (MACE) and stent thrombosis in DES-implanted AMI patients in real-life clinical practice. METHODS AND RESULTS: On-line registry of AMI cases at the web site www.kamir.or.kr has been performed in 41 primary PCI centers in Korea and between November 2005 and September 2006, 1,541 surviving patients who had been implanted with either Cypher or Taxus stents were enrolled for analysis during a 6-month clinical follow-up. There were 2 groups: group I [834 patients, 61.9+/-11.9 years: sirolimus-eluting stent (Cypher)], group II [707 patients, 62.9+/-12.0 years: paclitaxel-eluting stent (Taxus)]. At both 1 and 6 months the incidence of MACE was not significantly different between the 2 groups. There were 17 cases of stent thrombosis, but the incidence of stent thrombosis was not significantly different between the 2 groups (group I:II=9 (1.1%):8 (1.1%), p=1.000). The stent type, length, number, lesion complexity and diabetes were not significant for the incidence of MACE or stent thrombosis after adjustment. CONCLUSION: MACE and stent thrombosis rates did not differ between 2 types of DES identified in Korea Acute Myocardial Infarction Registry (KAMIR). DES can be used in patients with AMI with a relatively low 6-month MACE rate.     

THE RELATION BETWEEN RISK AND PROTECTIVE FACTORS FOR PROBLEM BEHAVIORS AND DEPRESSIVE SYMPTOMS,ANTISOCIAL BEHAVIOR,AND ALCOHOL USE IN ADOLESCENCE

Both externalizing and internalizing psychopathology increase throughout adolescence and a similar set of risk and protective factors may underlie depressive symptoms, antisocial behavior, and alcohol use. Analyses test how risk and protective factors for externalizing behavior in community, school, family, peer, and individual domains are related to depressive symptoms, antisocial behavior, and alcohol use concurrently and longitudinally in a sample of 2,002 students assessed in 8^th and 10^th grades (52% male; 58% Caucasian). Findings indicate that risk and protective factors for antisocial behavior and alcohol use are also associated with depressive symptoms, both concurrently and longitudinally. Prevention approaches that target risk and protective factors for externalizing problems may have crossover effects on depressive symptoms during adolescence.     

Descriptive and Prospective Analysis of Young Adult Alcohol Use and Romantic Relationships: Disentangling between- and within-Person Associations Using Monthly Assessments

Background: Prior research on romantic relationships and alcohol use among young adults has not distinguished between differences in patterns of relationship status over extended periods of time and within-person changes in status that only occur for some individuals. Objectives: This study captured between-person differences in relationship patterns, assessed associations between relationship patterns and alcohol use, and examined within-person associations between alcohol use and relationship status changes. In addition, age and sex differences in between- and within-person associations were tested. Methods: We used multilevel modeling of monthly data collected over one year on alcohol use and romantic relationship status from a Seattle area community sample of 620 young adults (ages 18–24). Results: Participants were coded into six relationship pattern groups: (1) single-not-dating (16%), (2) stable-in-a-relationship (30%), (3) single-dating (10%), (4) ended-a-relationship (14%), (5) started-a-relationship (13%), and (6) ended-and-started-a-relationship (18%). Single-not-dating and stable-in-a-relationship groups reported the least drinking across the entire year; the single-dating, ended-a-relationship, and ended-and-started-a-relationship groups reported higher levels of drinking. Examining within-person changes in groups 3–6 revealed increases in drinking associated with months of dating among the single-dating group, months postbreakup among the ended-a-relationship group, and months of breaking up and starting a new relationship among the ended-and-started-a-relationship group. Few differences by age or sex were found for between- or within-person associations. Conclusions: The findings point to heterogeneity in patterns of relationship status over time, differences in relationship patterns associated with variations in drinking, and particular time points of elevated risk for young adults who experience changes in status.     

The development of resistance in different inbred strains of mice to infection with Nematospiroides dubius

Infection by the intestinal nematode parasite Nematospiroides dubius was studied in seven different inbred mouse strains. Although there was some minor variation in the susceptibility of the different strains to a primary infection there were marked differences in their ability to develop resistance to infection following repeated exposure to infective larvae. The strains of mice which developed the best resistance also expelled adult worms arising from the previous infections. The adult worms resulting from a primary infection were slowly eliminated in two inbred strains studied whereas no loss occurred from outbred LACA mice. Although males and females of two strains, C3H/HeJ and CBA/H were equally susceptible to a primary infection, the females developed better resistance than the male mice following two oral administrations of third stage larvae. Infected mice of every strain and both sexes contained high levels of IgG1 in the serum.     

Criterion validity of the Short Mood and Feelings Questionnaire and one- and two-item depression screens in young adolescents

Background  

The use of short screening questionnaires may be a promising option for identifying children at risk for depression in a community setting. The objective of this study was to assess the validity of the Short Mood and Feelings Questionnaire (SMFQ) and one- and two-item screening instruments for depressive disorders in a school-based sample of young adolescents.     

Comparing quality of care for sexually transmitted diseases in specialized and general clinics

OBJECTIVE: The objective of this study was to compare quality of care for patients with sexually transmitted diseases (STDs) in specialized vs. general clinics. METHODS: The authors conducted a retrospective chart review evaluating compliance with a set of STD-related process of care quality indicators for adult patients seen in six Los Angeles County clinics (two STD specialized clinics and four general medical clinics). RESULTS: Thirty-two quality indicators were selected using a modified Delphi process. From March 1, 1996, to June 31, 1996, there were 205 STD-related visits to the two specialized STD clinics and 373 STD-related visits to the four general medical clinics. For patients with "classic" STDs (those for which sexual contact is the primary means of transmission), STD clinics achieved greater compliance than general medical clinics on 14 quality indicators, while general medical clinics achieved greater compliance on 4 indicators. CONCLUSION: STD clinics provide better overall STD care than general medical clinics. Possible explanations include differences in clinician experience with STD patients and greater use of standardized protocol sheets.
