On the Problems of Epibioses, Fouling and Artificial Reefs, a Review

Abstract: . Artificial reefs in marine environments are in most cases submerged structures consisting of dumped waste material or specific constructions made with the purpose of enriching the local fish populations and other marine life to the benefit of recreational and commercial fisheries. Such structures are susceptible to fouling and will successively develop assemblages, which may or may not resemble epibioses on natural substrata. Studies of artificial reefs have focused predominantly on fish assemblages and have largely disregarded the development of sessile biota and their structural and functional relationships. In addition, most studies are from tropical or subtropical environments. To manage and understand artificial reefs, a whole-ecosystem approach is necessary, incorporating studies of all aspects of hard substratum ecology including both structural and functional variables. This review is an attempt to evaluate the present knowledge of ecological aspects of artificial reefs, emphasising the role of sessile hard substratum biota.

A Randomized Controlled Trial of Nurse-led Care for Symptomatic Moderate-Severe Obstructive Sleep Apnea

Abstract: Rationale: Obstructive sleep apnea (OSA) is a prevalent disease. Often limited clinical resources result in long patient waiting lists. Simpler validated methods of care are needed.Objectives: To demonstrate that a nurse-led model of care can produce health outcomes in symptomatic moderate–severe OSA not inferior to physician-led care.Methods: A randomized controlled multicenter noninferiority clinical trial was performed. Of 1,427 potentially eligible patients at 3 centers, 882 consented to the trial. Of these, 263 were excluded on the basis of clinical criteria. Of the remaining 619, 195 met home oximetry criteria for high-probability moderate–severe OSA and were randomized to 2 models of care: model A, the simplified model, using home autoadjusting positive airway pressure to set therapeutic continuous positive airway pressure (CPAP), with all care supervised by an experienced nurse; and model B, involving two laboratory polysomnograms to diagnose and treat OSA, with clinical care supervised by a sleep...

Effects of testimonial inconsistencies and eyewitness confidence on mock-juror judgments.

Abstract: This study examined the interaction between testimonial consistency and eyewitness confidence on mock-jurors' judgments of probability that the defendant committed the crime and verdicts. In a 2 (testimonial consistency) x 2 (confidence) between-groups design, 130 mock-jurors listened to an audio-taped trial of a person charged with armed robbery. Manipulations were contained in the prosecution witness's responses to detailed questioning by prosecution and defense attorneys. Although consistency is considered to be a key marker of accuracy, its impact on judgments was weak and nonsignificant. Witness confidence had a strong influence on judgments, whether testimony was consistent or inconsistent. We suggested that witness confidence may be more likely to emerge as a dominant influence on juror judgments when the testimony is wide ranging rather than relatively brief and concerned only with a specific issue (e.g., identification confidence).

Family Functioning and Overprotection following a Natural Disaster: The Longitudinal Effects of Post-Traumatic Morbidity:

Abstract: The longitudinal impact of a natural disaster on the patterns of interaction in families with latency-aged children is examined. An 11-item questionnaire was developed and two factors were isolated: irritable distress and involvement. A group of 183 disaster-affected families were contrasted with 497 families who had not been exposed to the disaster. Eight months after the disaster, the interaction in the disaster-affected families was characterised by increased levels of conflict, irritability and withdrawal. Maternal overprotection was also a common feature of the pattern of care in these families. Post-traumatic morbidity in parents was the major determinant of the observed changes in family functioning and the overprotection.

Comparison of a brush-sampling fecal immunochemical test for hemoglobin with a sensitive guaiac-based fecal occult blood test in detection of colorectal neoplasia

Abstract: BACKGROUND. Fecal immunochemical tests (FIT) are an advanced fecal occult blood test (FOBT) technology that reduces barriers to population screening by simplifying the logistics of stool-sampling. The current study was conducted to undertake a paired comparison of a sensitive guaiac FOBT (GFOBT; Hemoccult II Sensa, Beckman Coulter, Fullerton, CA) with a brush-sampling FIT (InSure; Enterix, North Ryde, NSW, Australia), to determine whether this FIT improves detection of significant neoplasia. METHODS. Individuals sampled consecutive stools, at home, with both FIT and GFOBT sampling devices while following dietary restrictions appropriate for GFOBT. Study populations included a screening cohort (n = 2351) and a symptomatic diagnostic group (n = 161). Paired comparison of positivity rates was undertaken in those found to have cancer and/or significant adenoma (high-grade dysplasia, villous change, ≥10 mm, serrated histology or ≥3 polyps), benign pathology, or no pathology. RESULTS. Combined results for both cohorts showed that the FIT returned a true-positive result significantly more often in cancer (n = 24; 87.5% vs. 54.2%) and in significant adenomas (n = 61; 42.6% vs. 23.0%). Of all UICC Stage I cancers, the FIT was positive in 12 of 13 compared with 4 of 13 with the GFOBT (P = .002). In analyses of just the screening cohort, the FIT remained significantly better at detecting cancers and significant adenomas; the false-positive rate for any neoplasia was marginally higher with the FIT than the GFOBT (3.4% vs. 2.5%; 95% CI of difference, 0–1.8%), whereas positive predictive values were 41.9% and 40.4%, respectively. CONCLUSIONS. This brush-sampling FIT is more sensitive for cancers and significant adenomas than a sensitive GFOBT. As such, it should deliver greater reductions in colorectal cancer mortality and incidence than the GFOBT. Cancer 2006; © 2006 American Cancer Society.
