[Evaluation of the impact of recreational dive activity on the community structure of some coral reefs at Los Roques Archipelago National Park, Venezula].

In order to evaluate if snorkeling had significant effects on coral community structure, three different coral reefs (Madrizquí, Pelona de Rabusquí and Crasquí) located at Archipelago Los Roques National Park, Venezuela, were surveyed. For each site, the coral community structure of two different areas, one subjected to intense snorkeling use (FB) and other not frequently used (PFB), were compared. Community structure was determined with 1 m2-quadrants and 20 m-long transects. These communities were described in terms of species richness, diversity (Shannon-Wiener) and evenness indexes, live and dead coral cover and cover of other organisms (sponges, octocorals and algae). Comparisons within sites were performed with a Kruskall-Wallis test. A total of 24 species of scleractinian corals were found. Live coral cover ranged from 29.9% +/- 26.43 (Crasquí) to 34.55% +/- 6.43 (Madrizquí), while dead coral cover ranged from 32.51% +/- 2.86 (Madrizquí) to 60.78% +/- 21.3 (Pelona de Rabusquí). The PFB areas showed higher live coral cover compared to FB areas; however, significant differences were only found in Crasquí and Pelona de Rabusquí (p < 0.05). Species richness, diversity and evenness were variable and no trends were observed between FB and PFB areas. The frequency of both damaged and diseased colonies were low (< 1%), most damages observed were natural (parrotfish predation). Damages caused by divers such as fin impacts, were not found at the reefs studied. These results suggest that, currently, diving pressure is not as high to cause massive loses of live coral cover in these reefs. However, the lack of strict controls for these activities might produce long-term changes in the structure of these coral communities.

A civic engagement paradigm for reforming health administration education and recreating the community.

The education of students of health administration has traditionally combined both the theoretical and practical to enhance and balance the learning experience. Classroom exposure to the principles of management, law, organizations, and finance is coupled with problem solving, practicum, internship, and administrative residency experiences. However, just as recent years have seen the developmentof courses from managed care and alternative delivery systems to total quality management and continuous quality improvement, there is also emerging an awareness of the need to enhance the practical side of the learning equation. Perhaps this need is finding expression in curricular opportunities for students to learn from a participatory model known as civic engagement (CE). CE is a way of integrating academic study and community service to strengthen learning while promoting civic and personal responsibility to strengthen communities. Based on experiences with graduate and undergraduate students spanning the last ten years at Texas State University--San Marcos (Texas State), it is suggested that a CE paradigm has been developed within the Department of Health Administration that merits consideration by other programs of health administration. As a model for change, it has the potential for reforming both health administration education and most other higher education disciplines as well.

Recreational amitriptyline abuse.

UNLABELLED: Amitriptyline is a potent anticholinergics, rarely used as a drug of abuse. Two cases of amitriptyline dependency lasting for almost twelve months were described. According to the patients the abuse with amitriptyline guarantee them safety not to be uncovered by parents and doctors who systematically checked their urine with typical narcotic tests. CASE REPORT: Two patients with a history of abuse with amphetamine and clonazepam were admitted to the Clinic because of intoxication with amitriptyline. They denied the suicidal attempt and explained that they used amitriptyline in a dosage of 100 to 200 mg per day as a drug of abuse. On the day of admission one of the patients had increased the dosage up to 600 mg which caused an acute intoxication. CONCLUSION: Antidepressants should be treated as a drugs with possible abuse ability.

[Pregnancy and recreational physical activity].

Recent research indicates that physical activity before and during pregnancy helps lower the risk of gestational diabetes and preeclampsia. Physical activity during pregnancy has no negative effects on the risk of preterm birth, low birth weight and birth complications; however, thus far the topic has not been widely explored. In the light of the available findings, although of limited scope, it seems justified to encourage healthy pregnant women who are already physically active at the onset of pregnancy to maintain their activities but to reduce their intensity and to encourage pregnant women who are not already physically active to initiate physical activity.

Plasma glucose response to recreational diving in novice teenage divers with insulin-requiring diabetes mellitus.

A growing number of individuals with insulin-requiring diabetes mellitus (IRDM) dive, but data on plasma glucose (PG) response to diving are limited, particularly for adolescents. We report on seven 16-17 year old novice divers with IRDM participating in a tropical diving camp who had recent at least moderate PG control (HbA1c 7.3 +/- 1.1%) (mean +/- SD). PG was measured at 60, 30 and 10 min pre-dive and immediately following 42 dives. Maximum depth (17 +/- 6 msw) and total underwater times (44 +/- 14 min) were not extreme. Pre-dive PG exceeded 16.7 mmol x L(-1) (300 mg x dL(-1)) in 22% of dives. Males had significantly higher pre-dive levels (15.4 +/- 5.6 mmol x L(-1) [277 +/- 100 mg x dL(-1)] vs. 12.8 +/- 2.9 mmol x L(-1) [230 +/- 52 mg x dL(-1)], respectively) and greater pre-post-dive changes (-4.3 +/- 4.4 mmol x L(-1) [-78 +/- 79 mg x dL(-1)] vs. -0.5 +/- 4.3 mmol x L(-1) [-9 +/- 77 mg x dL(-1)], respectively). Post-dive PG was < 4.4 mmol x L(-1) [< 80 mg x dL(-1)] in two dives by two different males (3.4 and 3.9 mmol x L(-1) [61 and 70 mg x dL(-1)]). No symptoms or complications of hypoglycemia were reported. These data show that in a closely monitored situation, and with benign diving conditions, some diabetic adolescents with good control and no secondary complications may be able to dive safely. The impact of purposeful elevation of PG to protect against hypoglycemia during diving remains to be determined.

Age associated risks of recreational scuba diving.

The effect of aging on risk for development of decompression illness in divers has often been reported as an incidental finding in epidemiological analyses of diving accidents. No previous publications have specifically attempted to quantify or qualify those risks if present. This study demonstrates that aging increases risk for injury overall, serious injury in particular, and lessens recovery potential.

Recreational sports and the weekend athlete.

It is important to design an exercise program that provides an adequate amount of activity to attain maximal benefits at the lowest risk to the participant. Permanent lifestyle changes in eating and activity habits should be included in the primary goals of all programs.
