Knowledge, attitude and behavior among patients with Chlamydia. Perspectives for prevention

Patients with chlamydial infections (Ct) attending the outpatient Venereal Disease Clinic of Copenhagen from July 1-November 30 1995 were asked to fill in a questionnaire focusing upon knowledge, attitude and behaviour related to sexually transmitted diseases (STDs) in order to strengthen the future prevention of Ct. The questionnaire was answered by 37 men and 35 women with a median age of 27 and 21 years and a median number of three and two sexual partners within the last six months, respectively. Half of the patients had previously had an STD, and 92% had been tested for HIV, of whom one homosexual man was known HIV-positive. Notification about exposure from a partner was the reason for attending for 24%. All but one were in favour of partner notification, but only 6% wanted provider referral. During last intercourse condoms had neither been used with a steady partner by 75% especially by the young and women, who thought themselves safe, nor with a casual partner by 52% especially among the young and men, mainly because of thoughtlessness or perception of low risk. Before the actual STD diagnosis only 49% were able to name one symptom and 35% one complication related to Ct. A majority (79%) stated, that fear of catching another Ct would lead to better protection, and 70% found that more information would have a preventive effect. Future Ct prevention programs in Denmark should include intensified chlamydial screening and partner notification together with centrally produced mass media information supplemented by individual counselling.     

Atmospheric Chemistry of 2-Ethyl Acrolein

The atmospheric oxidation of the unsaturated aldehyde 2-ethyl acrolein, CH₂=C(C₂H₅)CHO, has been studied in laboratory experiments involving the reaction of ozone with 2-ethyl acrolein in the dark (with cyclohexane added to scavenge the hydroxyl radical), and the sunlight irradiation of 2-ethyl acrolein with NO in air. The major carbonyl products of the 2-ethyl acrolein reaction with ozone are formaldehyde, acetaldehyde, and the dicarbonyl ethylglyoxal, CH₃CH₂COCHO. Sunlight irradiation of 2-ethyl acrolein and NO led to the formation of three carbonyls (formaldehyde, acetaldehyde, and ethylglyoxal) and three peroxyacyl nitrates, (RC(O)OONO₂), including PAN (R = CH₃), PPN (R = C₂H₅), and the unsaturated compound EPAN (R = CH₂=C(C₂H₅)). Mechanisms are outlined for the reactions of ozone and of the hydroxyl radical with 2-ethyl acrolein. These mechanisms are consistent with the observed carbonyl and peroxyacyl nitrate products. Thermal decomposition, a major atmospheric removal process for peroxyacyl nitrates, has been studied for EPAN. The decomposition rate of EPAN relative to that of PAN is 0.59–0.73 at 292–294 K and 1 atm of air. Atmospheric implications of these results are discussed.     

Using the Megargee MMPI-based classification system with the MMPI-2s of female prison inmates.

This study extends Megargee's Minnesota Multiphasic Personality Inventory (MMPI)-based classification system to female offenders. MMPI-2s of 400 women in state and federal prisons were rescored and reconfigured to estimate their original MMPI profiles. Their MMPIs and MMPI-2s were classified according to the rules devised for the original MMPI. Next, the MMPI-2s were reclassified using new rules for classifying the MMPI-2s of male offenders. Neither approach led to satisfactory agreement between MMPI and MMPI-2. A major problem was that Scale 5 was more prominent in the women's MMPI-2 profiles than on their MMPIs. Using revised rules for classifying the original MMPIs and the MMPI-2s of female offenders, 386 of the 400 women (97%) could be classified on both versions of the MMPI, of whom 336 (87%) were classified identically.

Effect of Feathery Mottle Virus Infection on Sweet Potato Sensory Properties

Four sets of sweet potato clones obtained by meristem tip culture were used to investigate the effect of feathery mottle virus (FMV) infection on the appearance, sensory quality and chemical composition of the storage roots. This study, encompassing four generations, indicated that FMV infection had a slight effect on carbohydrate metabolism but no effect on the polyphenoloxidase-phenol system. Flavor and texture profile analyses indicated that for one clone, FMV-infected roots were more desirable when baked than healthy roots. Considering the study as a whole, FMV infection did not appear to adversely affect sweet potato sensory properties. Clones produced from the same parent by meristem tip culture might have different compositional and sensory properties.
