Developing the future nurse leaders of Fiji.

BACKGROUND: Nurse leaders in Fiji are currently involved in meeting the challenges of being at the forefront of an AusAID supported Health Sector Improvement process. Fiji is experiencing the same shortages of health professionals (including nurses) as is occurring internationally, while simultaneously striving to improve the quality of its health services. PRIMARY ARGUMENT: This paper provides information about the current situation in relation to health services in Fiji, and describes strategies being undertaken by the nurse leaders of Fiji to meet the challenge of leading an exciting reform process. James Cook University, School of Nursing Sciences, has been privileged to support the provision of contemporary leadership and management education for current and future nurse leaders in the Fiji Health Sector as a component of a current education program to educate registered nurses to bachelor level. This paper will provide an overview of the current Fiji Health Sector Improvement Program, with a particular focus on the preparation of nurse leaders. CONCLUSION: There is an ongoing need to understand beliefs and values, and styles of interaction and communication, and indeed, ideas about time. With collaboration between Australian academics and Fiji tutors from the Fiji School of Nursing, the program appears to be remarkably successful.     

A pilot sequential study of cognitive therapy and pharmacotherapy of atypical depression.

BACKGROUND: Parallel comparison studies of cognitive therapy and antidepressant medication have suggested that both treatments are effective. However, we cannot determine from these studies whether cognitive therapy and antidepressant medication are effective for the same populations of depressives. A sequential study in which nonresponders to the first treatment are then treated with the second can address this issue. METHOD: Twenty-seven patients meeting DSM-III criteria for major depression or dysthymic disorder and Columbia criteria for atypical depression received cognitive therapy followed by antidepressant medication for cognitive therapy nonresponders. A response rate with the second treatment equal to that expected with placebo would suggest both treatments target the same depressive population. RESULTS: Of the 25 completers of the study, 14 (56%) were judged responders to cognitive therapy alone. Sixty-nine percent (9/13) of the responders maintained their benefits for 6 months or more. Seven of the 11 cognitive therapy nonresponders (63%) responded to antidepressant medication. These results were compared with those of a concurrent double-blind medication study; both its sample and ours were drawn from the same population at the same time: cognitive therapy and antidepressant medication response rates were higher than expected with placebo (28%). CONCLUSION: The results suggest that (1) cognitive therapy and antidepressant medication are effective treatments for differing populations of depressed patients, as the antidepressant medication response of cognitive therapy nonresponders was greater than expected with placebo, and (2) cognitive therapy has a lasting effect.     

Cardiac conduction abnormalities and rhythm changes after neonatal anatomical correction of transposition of the great arteries.

Seventy three infants who underwent neonatal anatomical correction for transposition of the great arteries with or without a ventricular septal defect were reviewed for evidence of conduction and rhythm abnormalities on preoperative and postoperative 12 lead electrocardiograms and during 24 hour Holter monitoring. There was a partial right bundle branch block pattern in 47% (29/62) of all patients and in 60% (24/40) of those with simple transposition. Complete right bundle branch block was noted in 21% including 5% with simple transposition. Holter monitoring showed sinus rhythm in all patients except three: one had episodes of supraventricular tachycardia, another an intermittent second degree heart block, and a third a complete heart block. Atrial extrasystoles were noted in 47% (29/62) of patients but were frequent in only three patients. Occasional unifocal ventricular extrasystoles were encountered in 37% (23/62) of patients and were frequent in a further 3% (2/62). Only one patient (2%) developed multifocal ventricular extrasystoles. The frequency of important cardiac arrhythmias after neonatal anatomical correction of transposition of the great arteries was 5%, significantly less than that reported after atrial inflow diversion for the same malformation.     

Gallstones Containing Bacteria are Biofilms: Bacterial Slime Production and Ability to Form Pigment Solids Determines Infection Severity and Bacteremia

Objective Gallstone bacteria provide a reservoir for biliary infections. Slime production facilitates adherence, whereas β-glucuronidase and phospholipase generate colonization surface. These factors facilitate gallstone formation, but their influence on infection severity is unknown. Methods Two hundred ninety-two patients were studied. Gallstones, bile, and blood (as applicable) were cultured. Bacteria were tested for β-glucuronidase/phospholipase production and quantitative slime production. Infection severity was correlated with bacterial factors. Results Bacteria were present in 43% of cases, 13% with bacteremia. Severe infections correlated directly with β-glucuronidase/phospholipase (55% with vs 13% without, P < 0.0001), but inversely with slime production (55 vs 8%, slime <75 or >75, P = 0.008). Low slime production and β-glucuronidase/phospholipase production were additive: Severe infections were present in 76% with both, but 10% with either or none (P < 0.0001). β-Glucuronidase/phospholipase production facilitated bactibilia (86% with vs 62% without, P = 0.03). Slime production was 19 (±8) vs 50 (±10) for bacteria that did or did not cause bacteremia (P = 0.004). No bacteria with slime >75 demonstrated bacteremia. Conclusions Bacteria-laden gallstones are biofilms whose characteristics influence illness severity. Factors creating colonization surface (β-glucuronidase/phospholipase) facilitated bacteremia and severe infections; but abundant slime production, while facilitating colonization, inhibited detachment and cholangiovenous reflux. This shows how properties of the gallstone biofilm determine the severity of the associated illness.
