On the fast track speeding nurses into the future: a two year Bachelor of Nursing for graduates of other disciplines

It has been suggested in nursing literature that a bachelor's degree should be the pre-requisite to professional nursing education and registration. The perceived advantages of graduates entering the nursing profession led faculty in the School of Nursing La Trobe University to introduce in 1997 an innovative two-year Bachelor of Nursing (BN) program, believed to be the first in Australia, for graduates of other disciplines. A problem-based learning (PBL) approach was selected to facilitate the teaching learning process. Data to evaluate the progress of the accelerated students were collected by examining their previous degree background, conducting a focus group discussion mid year and comparing the students' academic results with those completing the traditional three-year course. Findings indicate that students in the accelerated course were highly motivated but experienced significant stress. In part the stress emanated from the need to identify their own learning needs. However, despite their concerns most accelerated students scored at least as well both clinically and academically as traditional students. Moreover, in six of the seven final year subjects each group studied the accelerated students performed better.

Two-year combination antibiotic therapy with clarithromycin, rifabutin, and clofazimine for Crohn's disease

Background & Aims: Mycobacterium avium subspecies paratuberculosis has been proposed as a cause of Crohn’s disease. We report a prospective, parallel, placebo-controlled, double-blind, randomized trial of 2 years of clarithromycin, rifabutin, and clofazimine in active Crohn’s disease, with a further year of follow-up. Methods: Two hundred thirteen patients were randomized to clarithromycin 750 mg/day, rifabutin 450 mg/day, clofazimine 50 mg/day or placebo, in addition to a 16-week tapering course of prednisolone. Those in remission (Crohn’s Disease Activity Index ≤150) at week 16 continued their study medications in the maintenance phase of the trial. Primary end points were the proportion of patients experiencing at least 1 relapse at 12, 24, and 36 months. Results: At week 16, there were significantly more subjects in remission in the antibiotic arm (66%) than the placebo arm (50%; P = .02). Of 122 subjects entering the maintenance phase, 39% taking antibiotics experienced at least 1 relapse between weeks 16 and 52, compared with 56% taking placebo (P = .054). At week 104, the figures were 26% and 43%, respectively (P = .14). During the following year, 59% of the antibiotic group and 50% of the placebo group relapsed (P = .54). Conclusions: Using combination antibiotic therapy with clarithromycin, rifabutin, and clofazimine for up to 2 years, we did not find evidence of a sustained benefit. This finding does not support a significant role for Mycobacterium avium subspecies paratuberculosis in the pathogenesis of Crohn’s disease in the majority of patients. Short-term improvement was seen when this combination was added to corticosteroids, most likely because of nonspecific antibacterial effects.

IT skills of university first year undergraduate students : two 2001 matriculation cohorts

The use of computers is becoming more widespread in education and in the wider Australian community. This communication reports the results of surveys of two cohorts of first year undergraduate students at The University of Western Australia and Deakin University, conducted at the beginning of the 2001 academic year. The surveys confirm that general IT skills among students are increasing, but that the level of skill is variable. This is consistent with a similar survey at Deakin University which was conducted at the beginning of 2000.

Part-time employment trends for full-time undergraduate property and construction students : results of a two year sequential investigation

This paper reports on the initial findings of an investigation into the experiences and part-time work practices of undergraduates enrolled in the Bachelor of Property and Construction (BPC) and combined degree courses at the University of Melbourne. Initial data was collected from final year students during 2001 and for all four years of the course in 2002. The results suggest that students in earlier years of the course are more likely to work in non-industry (casual) related employment and work fewer hours. Students in later years of the BPC course are more likely to work in jobs in the construction industry and also to work longer hours than those in earlier years. An analysis of final year students shows that the students employed by contracting organisations work significantly more hours than students employed by other types of organisations including architectural practices. The consequences of part-time semester employment on academic performance and students' well-being are considered and proposals are put forward as to how to better manage the industry experience-University relationship.

Two-year results of a randomized placebo-controlled trial of vertebroplasty for acute osteoporotic vertebral fractures

We previously reported the results of a randomized controlled trial that found no benefit of vertebroplasty over a sham procedure for acute osteoporotic vertebral fractures up to 6 months. We report here the 12-month and 24-month clinical outcomes of this trial. Eligible participants (n = 78) were randomly assigned to receive either vertebroplasty (n = 38) or a sham procedure (n = 40). Randomization was stratified by treatment center, sex, and symptom duration (<6 weeks or ≥6 weeks). Participants, investigators (except the treating radiologists), and outcome assessors were blinded to group assignments. Enrolment occurred between April 2004 and October 2008 with follow-up completed October 2010. The primary outcome was overall pain measured on a scale of 0 (no pain) to 10 (maximal imaginable pain). Secondary outcomes included pain at rest and at night, disability, quality of life, perceived recovery, and adverse events, including incident clinically apparent vertebral fractures. At 12 and 24 months, complete data were available for 67 (86%) and 57 (73%) participants, respectively. At 12 months participants in the active group improved by 2.4 ± 2.7 (mean ± SD) units in overall pain compared with 1.9 ± 2.8 units in the sham group, adjusted between-group mean difference (MD) 0.3 (95% confidence interval [CI], –0.9 to 1.5), whereas at 24 months participants in the active group had improved by 3.0 ± 3.1 units compared with 1.9 ± 3.0 units in the sham group, MD 1.1 (95% CI, –0.3 to 2.4). No significant between-group differences were observed for any of the secondary efficacy outcomes at 12 or 24 months. There were no between-group differences in incident clinical vertebral fractures up to 24 months (active: n = 14, sham: n = 13), although the study had inadequate power for this outcome. These results provide further evidence that the use of this treatment in routine care is unsupported.

Mental health diversion courts: a two year recidivism study of a South Australian mental health court program.

The need to develop specialized judicial processes to deal with offenders with mental illnesses is now widely recognized and has led to the introduction of mental health court diversion programs around the world. At present, however, there is only limited evidence from which to assess the impact of these initiatives. This paper describes the South Australian model of diversion, with specific reference to the relationship between identified participant characteristics, program compliance rates, and re-offending outcomes. The results of a two-year recidivism study suggest that involvement with the program has a positive impact on recidivism, but that this is independent from the individual's level of success in the program. Lower risk offenders were more likely to achieve successful outcomes than those in the higher risk categories. The implications of these results, as well the factors that might inform the ongoing development of mental health court programs, are discussed.

Clinical evaluation of two packable resin-based composite restorations: A three-year report

This randomized clinical trial sought to evaluate the performance of two packable composites over a period of 36 months. A total of 39 Class I and II restorations were placed in the permanent teeth of 20 patients. Using United States Public Health Services criteria, two investigators evaluated the restorations immediately after placement and again after 12 and 36 months, examining color match, marginal discoloration, marginal integrity, recurrent caries, proximal contact, anatomical shape, surface texture, and postoperative sensitivity. It was concluded that the packable composites evaluated showed satisfactory clinical performance after three years.

Bonding all-ceramic restorations with two resins cement techniques: A clinical report of three-year follow-up

Ceramics have been widely used for esthetic and functional improvements. The resin cement is the material of choice for bonding ceramics to dental substrate and it can also dictate the final esthetic appearance and strength of the restoration. The correct use of the wide spectrum of resin luting agents available depends on the dental tooth substrate. This article presents three-year clinical results of a 41 years old female patient B.H.C complaining about her unattractive smile. Two all-ceramic crowns and two laminates veneers were placed in the maxillary incisors and cemented with a self-adhesive resin luting cement and conventional resin luting cement, respectively. After a three-year follow-up, the restorations and cement/teeth interface were clinically perfect with no chipping, fractures or discoloration. Proper use of different resin luting cements shows clinical appropriate behavior after a three-year follow-up. Self-adhesive resin luting cement may be used for cementing all-ceramic crowns with high predictability of success, mainly if there is a large dentin surface available for bonding and no enamel at the finish line. Otherwise, conventional resin luting agent should be used for achieving an adequate bonding strength to enamel.

Two-year Clinical Performance of Self-etching Adhesive Systems in Composite Restorations of Anterior Teeth

Objective: The aim of this study was to evaluate the two-year clinical performance of Class III, IV, and V composite restorations using a two-step etch-and-rinse adhesive system (2-ERA) and three one-step self-etching adhesive systems (1-SEAs).Material and Methods: Two hundred Class III, IV, and V composite restorations were placed into 50 patients. Each patient received four composite restorations (Amaris, Voco), and these restorations were bonded with one of three 1-SEAs (Futurabond M, Voco; Clearfil S3 Bond, Kuraray; and Optibond All-in-One, Kerr) or one 2-ERA (Adper Single Bond 2/3M ESPE). The four adhesive systems were evaluated at baseline and after 24 months using the following criteria: restoration retention, marginal integrity, marginal discoloration, caries occurrence, postoperative sensitivity and preservation of tooth vitality. After two years, 162 restorations were evaluated in 41 patients. Data were analyzed using the chi(2) test (p<0.05).Results: There were no statistically significant differences between the 2-ERA and the 1-SEAs regarding the evaluated parameters (p>0.05).Conclusion: The 1-SEAs showed good clinical performance at the end of 24 months.

Comparative clinical study of the effectiveness of different dental bleaching methods - two year follow-up

This study evaluated color change, stability, and tooth sensitivity in patients submitted to different bleaching techniques. Material and methods: In this study, 48 patients were divided into five groups. A half-mouth design was conducted to compare two in-office bleaching bleaching techniques (with and without light activation): G1: 35% hydrogen peroxide (HP) (Lase Peroxide - DMC Equipments, Sao Carlos, SP, Brazil) + hybrid light (HL) (LED/Diode Laser, Whitening Lase II DMC Equipments, Sao Carlos, SP, Brazil); G2: 35% HP; G3: 38% HP (X-traBoost - Ultradent, South Jordan UT, USA) + HL; G4: 38% HP; and G5: 15% carbamide peroxide (CP) (Opalescence PF - Ultradent, South Jordan UT, USA). For G1 and G3, HP was applied on the enamel surface for 3 consecutive applications activated by HL. Each application included 3x3' HL activations with 1' between each interval; for G2 and G4, HP was applied 3x15' with 15' between intervals; and for G5, 15% CP was applied for 120'/10 days at home. A spectrophotometer was used to measure color change before the treatment and after 24 h, 1 week, 1, 6, 12, 18 and 24 months. A VAS questionnaire was used to evaluate tooth sensitivity before the treatment, immediately following treatment, 24 h after and finally 1 week after. Results: Statistical analysis did not reveal any significant differences between in-office bleaching with or without HL activation related to effectiveness; nevertheless the time required was less with HL. Statistical differences were observed between the result after 24 h, 1 week and 1, 6, 12, 18 and 24 months (integroup). Immediately, in-office bleaching increased tooth sensitivity. The groups activated with HL required less application time with gel. Conclusion: All techniques and bleaching agents used were effective and demonstrated similar behaviors.

Corneal wavefront-guided photorefractive keratectomy with mitomycin-C for hyperopia after radial keratotomy: Two-year follow-up

PURPOSE: To assess corneal wavefront-guided photorefractive keratectomy (PRK) to correct hyperopia after radial keratotomy (RK). SETTING: Sadalla Amin Ghanem Eye Hospital, Joinville, Santa Catarina, Brazil. DESIGN: Case series. METHODS: Excimer laser corneal wavefront-guided PRK with intraoperative mitomycin-C (MMC) 0.02% was performed. Main outcome measures were uncorrected (UDVA) and corrected (CDVA) distance visual acuities, spherical equivalent (SE), corneal aberrations, and haze. RESULTS: The mean time between RK and PRK in the 61 eyes (39 patients) was 18.8 years +/- 3.8 (SD). Before PRK, the mean SE was +4.17 +/- 1.97 diopters (D); the mean astigmatism, -1.39 +/- 1.04 D; and the mean CDVA, 0.161 +/- 0.137 logMAR. At 24 months, the mean values were 0.14 +/- 0.99 D (P<.001), -1.19 +/- 1.02 D (P=.627), and 0.072 +/- 0.094 logMAR (P<.001), respectively; the mean UDVA was 0.265 +/- 0.196 (P<.001). The UDVA was 20/25 or better in 37.7% of eyes and 20/40 or better in 68.9%. The CDVA improved by 1 or more lines in 62.3% of eyes. Two eyes (3.3%) lost 2 or more lines, 1 due to corneal ectasia. Thirty eyes (49.2%) were within +/- 0.50 D of intended SE and 45 (73.8%) were within +/- 1.00 D. From 6 to 24 months, the mean SE regression was +0.39 D (P<.05). A significant decrease in coma, trefoil, and spherical aberration occurred. Three eyes developed peripheral haze more than grade 1. CONCLUSION: Corneal wavefront-guided PRK with MMC for hyperopia after RK significantly improved UDVA, CDVA, and higher-order corneal aberrations with a low incidence of visually significant corneal haze.
