Suicidal Ideation, Planning, and Attempts among Canadian Coast Guard and Conservation and Protection Officers.

The current study provides estimates of suicidal ideation, planning, and attempts among Canadian Coast Guard personnel and Canadian Conservation and Protection Officers. Participants (n = 385; 59% men) completed a self-report survey that collected past-year and lifetime estimates of suicidal ideation, planning, attempts, sociodemographic information, and symptoms related to mental health disorders. Within the sample, participants reported lifetime suicidal ideation (25.7%), planning (10.9%), and attempts (5.5%). Participants reported past-year suicidal ideation (7.5%), planning (2.1%), and the percentage of attempts was too marginal to report due to ethical considerations. Canadian Coast Guard personnel and Conservation and Protection Officers reported higher percentages of past-year and lifetime suicidal ideation, planning, and attempts than the Canadian general population, but the percentages reported are comparable to other Canadian PSP sectors. No statistically significant results were observed for the sociodemographic covariates within the past-year, whereas, statistically significant results were observed for the lifetime sociodemographic covariates of age, province of residence, and previous work experience. There were statistically significant associations between past-year suicidal ideation and positive screens for major depressive disorder (MDD) and general anxiety disorder (GAD); as well, past-year suicidal planning was associated with social anxiety disorder (SAD). There were also statistically significant associations between lifetime suicidal ideation, planning, and attempts and positive screens for posttraumatic stress disorder (PTSD), MDD, and SAD. Lifetime suicidal ideation and planning were associated with panic disorder (PD). The current estimates provide valuable information for clinicians and stakeholders involved in prevention programs, treatment, or future research.

The effect of epidural anesthesia on safety and success of external cephalic version at term.

The purpose of this study was to assess the effect of epidural anesthesia on the success and safety of external cephalic version (ECV) performed at term. A retrospective record review of all pregnant women > 36 wk gestation who had attempts at ECV at Arnold Palmer Hospital for Children and Women between April 2, 1992, and April 30, 1993, was performed. The standard contraindications to ECVs were observed, and the use of tocolytics and lumbar epidural anesthesia was based on personal preference of the patient's physician. Sixty-one patients underwent 69 attempts, with eight patients having two attempts. There were 37 attempts without epidural and 32 with epidural. Four (10%) and 11 (34%) of the no epidural and epidural groups, respectively, were either in labor or had a cervical dilation > 3 cm at the time of the attempt. The other major patient variables likely to affect the success of ECV were not different between the groups, with the exception of a higher percentage of attempts by the housestaff in the epidural group. The success rate was 59% and 24% for the epidural group and no epidural group, respectively (P < 0.05). The incidence of abruptio placentae, fetal bradycardia, low Apgar scores, and low umbilical artery pH was similar. In our patient population, regional anesthesia increased the success rate of ECV and decreased the cesarean delivery rate with no apparent ill effect on perinatal or maternal morbidity or mortality.

Suicidal behavior among "normal" high school students.

The findings of a pilot study, focusing on suicidal behaviors among 313 high school students in the Midwest, are discussed. Of all the students who participated in the study, 62.6% reported some degree of suicidal ideation or action, including 8.4% who had actually made a suicide attempt. The current study provides a linchpin between the studies of adolescent suicide attempt rates and the studies reporting on percentages of adolescents who made suicide attempts. When the percentage of attempters who made attempts but did not seek medical help is taken under consideration, these two groups of studies become equivalent. Apparently, suicide is a personal concern for most high school students--a problem that warrants immediate attention.

Primary angiographic success rates of percutaneous transluminal coronary angioplasty

Three distinct periods in catheter design have been identified since the advent of percutaneous transluminal coronary angioplasty (PTCA) in 1977. In the first period PTCA was performed using a double-lumen balloon catheter that had a fixed, flexible guidewire at the tip. In the second period, an independent, steerable guidewire and the steerable catheter system were used. In the third period, low-profile catheters were introduced. A total of 2,969 patients who had single-vessel PTCA of a native coronary artery was separated into groups according to the period during which PTCA was performed. Introduction of the steerable catheter system was accompanied by improvement in primary success rate in PTCA attempts on the right coronary artery (78% vs 88%, p < 0.005). Introduction of the low-profile catheter was accompanied by improved primary success in PTCA attempts on the left anterior descending coronary artery (LAD) (90% vs 94%, p < 0.005). The percentage of PTCA attempts on the LAD decreased over the 3 periods (70% to 60% to 56%), while the percentage of attempts on the left circumflex artery increased (7% to 12% to 16%). Before steerable and low-profile catheters were used, there were significant differences in ability to reach and cross stenoses among the 3 major coronary arteries. These differences no longer exist. These results indicate that technical improvements and operator experience have made stenoses in all 3 major coronary arteries equally accessible to dilatation catheters and that primary success rates and reasons for failure in these arteries are now similar.

Effect of daily synchronization of sexual activity on mating success in laboratory populations of two species of Dacus (Diptera : Tephritidae)

In crowded laboratory populations of D. tryoni and D. neohumeralis, males of both species locate mates by random attempts at copulation with nearby adults, regardless of sex. But a much greater percentage of attempts by D. tryoni males resulted in copulation. The daily period of mating of D. tryoni in crowded laboratory populations was restricted to 1 hr at dusk while mating in populations of D. neohumeralis extended over a 7-hr period, earlier in the day. If it is assumed that individuals of both species remain sexually active for a similar duration of time each day then both the higher frequency of mating and the greater percentage of successful attempts at copulation found among D. tryoni can be explained by the resulting synchronization in time of sexual activity.

Experiments in Endobronchial Stenosis

The production of bronchial stenosis by the simple method of the endobronchial application of a caustic has given rise to considerable experimental work. Adams and Livingstone painted the orifice of a bronchus with a 35% silver nitrate solution, which resulted in complete stenosis of that bronchus in a high percentage of attempts. This demanded repetition in view of the many possibilities for the application of such a method in clinical conditions.Following the technique of Adams and Livingstone1 we have failed to produce complete stenosis in either dogs or monkeys in experiments during the last 1 1/2 years. Either we produced so great a destruction that rupture of the bronchus or a serious pneumonitis distal to the bronchus occurred, or stenosis failed to result. Stenosis with complete collapse of the lobe distal to this occurred in but a small percentage of our animals.The desirability of the method led to a search for other solutions which might be more efficacious. To produce a permanent bronchial occ...
