Skeletal Age Changes in \u3cem\u3eSaguinus fuscicollis\u3c/em\u3e and \u3cem\u3eSaguinus oedipus\u3c/em\u3e
The South American tamarin, genus Saguinus is used extensively as a model for interpreting human disease. Recently, techniques for estimating the age from skeletons of wild-caught tamarins have been requested by biomedical researchers. These skeletal aging techniques are subsequently used as an aid in documenting the timing of disease onset and latency periods.
Skeletal age changes are examined in 157 Saguinus fusaicollis and 59 Saguinus oedipus specimens of known age. The entire approximate 15 year life span of these animals is represented within the sample. The species are treated independently for all analyses. Documentation of the ontogenetic skeletal changes in immature specimens is made for the sequences and timing of dental eruption and epiphyseal union and for the chronology of long bone growth. For adult specimens, the age-related patterns associated with intracortical bone remodeling and mid-diaphyseal cortex size and shape are documented.
Results of this research indicate that the greatest accuracy for estimating age in these species is obtained within the developmental growth stage, from birth to maturity. During this stage, accurate age assignment can be made to within approximately three months. For aging adult specimens, the trends of intracortical bone remodeling and mid-diaphyseal cortex size and shape exhibit extensive intraspecies variation and thus are applicable with limited accuracy
Conferencing: An Exploration into Connectivity, Content, and Community
The electronic conference, Bits and Bytes: An Online Symposium on the Evolution of Technology in Education, was a joint initiative of the Faculty of Education at Memorial University of Newfoundland and the Centre for Advanced Placement Education at Discovery Collegiate. The format of this electronic conference (e-conference) was similar to that of an on-site conference, with a call for submissions, a peer-reviewed processing of these proposals, and a presentation of the accepted proposals. However, the participants of this e-conference never met in a specific locale in a synchronous time frame, as is the case with traditional conferences. The authors and participants interacted in a virtual sense, with presentations, commentary and feedback taking place in an asynchronous time frame
Cyber Insurance Effects on Cyber Hygiene: Does the Homeostatic Effect Apply?
A theoretical framework and research strategy is proposed to gain insight into perceptions and decisions as to how SMBs make decisions regarding cybersecurity hygiene measures, which could lead to betterinformed decisions regarding insurance as part of an ISA program, as well as have a bearing on policy structures and pricing for such insurance. This is because the definition of “cybersecurity hygiene habits”(CHH) as a task appears to vary within the industry and makes the practice hard to measure and evaluate. Research suggests that there may be a poorly understood connection between CHHs undertaken by organizations and their perceptions and/or adoption of cybersecurity insurance as well, thus leading to gaps or holes within business security perimeters. Homeostatic Risk Theory (HRT) has been observed in other venues in which the use of risk mitigation measures (including insurance) leads to more risky behavior; this may have a bearing on why so many organizations, particularly Small and Medium Businesses (SMBs) are very slow to adopt Information Security Assurance (ISA) measures at all or do so minimally. This paper presents a theoretical framework and proposed research, which will provide greater clarity on these issues while highlighting areas where further research is required
Asystole following Reintubation during Suspension Laryngoscopy
Transient increase in heart rate and mean arterial pressure commonly occur during manipulation of the airway via direct laryngoscopy. This phenomenon is understood to be due to a sympathetic nervous system reflex causing an increase in plasma catecholamines. Rarely, severe bradycardia and possible asystole can occur following laryngoscopy. One previous report described asystole during suspension laryngoscopy after uneventful direct laryngoscopy. Here we report a case of asystole occurring at the time of reinsertion and cuff inflation of an endotracheal tube in a patient who had been hemodynamically stable during initial direct laryngoscopy and the ensuing suspension laryngoscopy. The asystole was immediately recognized and successful cardiopulmonary resuscitation was performed with the patient returning to baseline sinus rhythm. Cardiac arrest following laryngoscopy is rare. This case highlights the importance of continued vigilance even after the initial manipulations of the airway by both direct laryngoscopy and suspension laryngoscopy are to be performed. Identifying patients who may benefit from premedication with a vagolytic drug may prevent adversity. Preoperative heart rate analysis can identify patients with strong vagal tone

Medication decision-making for patients with renal insufficiency in inpatient and outpatient care at a US Veterans Affairs Medical Centre: a qualitative, cognitive task analysis.
BackgroundMany studies identify factors that contribute to renal prescribing errors, but few examine how healthcare professionals (HCPs) detect and recover from an error or potential patient safety concern. Knowledge of this information could inform advanced error detection systems and decision support tools that help prevent prescribing errors.ObjectiveTo examine the cognitive strategies that HCPs used to recognise and manage medication-related problems for patients with renal insufficiency.DesignHCPs submitted documentation about medication-related incidents. We then conducted cognitive task analysis interviews. Qualitative data were analysed inductively.SettingInpatient and outpatient facilities at a major US Veterans Affairs Medical Centre.ParticipantsPhysicians, nurses and pharmacists who took action to prevent or resolve a renal-drug problem in patients with renal insufficiency.OutcomesEmergent themes from interviews, as related to recognition of renal-drug problems and decision-making processes.ResultsWe interviewed 20 HCPs. Results yielded a descriptive model of the decision-making process, comprised of three main stages: detect, gather information and act. These stages often followed a cyclical path due largely to the gradual decline of patients' renal function. Most HCPs relied on being vigilant to detect patients' renal-drug problems rather than relying on systems to detect unanticipated cues. At each stage, HCPs relied on different cognitive cues depending on medication type: for renally eliminated medications, HCPs focused on gathering renal dosing guidelines, while for nephrotoxic medications, HCPs investigated the need for particular medication therapy, and if warranted, safer alternatives.ConclusionsOur model is useful for trainees so they can gain familiarity with managing renal-drug problems. Based on findings, improvements are warranted for three aspects of healthcare systems: (1) supporting the cyclical nature of renal-drug problem management via longitudinal tracking mechanisms, (2) providing tools to alleviate HCPs' heavy reliance on vigilance and (3) supporting HCPs' different decision-making needs for renally eliminated versus nephrotoxic medications

Scoliosis Research Society members attitudes towards physical therapy and physiotherapeutic scoliosis specific exercises for adolescent idiopathic scoliosis
Background: Attitudes regarding non-operative treatment for adolescent idiopathic scoliosis (AIS) may be changing with the publication of BRAiST. Physiotherapeutic Scoliosis Specific Exercises (PSSE) are used to treat AIS, but high-quality evidence is limited. The purpose of this study is to assess the attitudes of members of the Scoliosis Research Society towards PSSE. Methods: A survey was sent to all SRS members with questions on use of Physical Therapy (PT) and PSSE for AIS. Results: The majority of the 263 respondents were from North America (175, 67 %), followed by Asia (37, 14 %) and Europe (36, 14 %). The majority of respondents (166, 63 %) prescribed neither PT nor PSSE, 28 (11 %) prescribed both PT and PSSE, 39 (15 %) prescribe PT only and 30 (11 %) prescribe PSSE only. PT was prescribed by 67 respondents, as an adjunct to bracing (39) and in small curves (32); with goals to improve aesthetics (27) and post-operative outcomes (25). Of the 196 who do not prescribe PT, the main reasons were lack of evidence (149) and the perception that PT had no value (112). PSSE was prescribed by 58 respondents. The most common indication was as an adjunct to bracing (49) or small curves (41); with goals to improve aesthetics (36), prevent curve progression (35) and improve quality of life (31). Of the respondents who do not prescribe PSSE, the main reasons were lack of supporting research (149), a perception that PSSE had no value (108), and lack of access (63). Most respondents state that evidence of efficacy may increase the role of PSSE, with 85 % (223 of 263) favoring funding PSSE studies by the SRS. Conclusion: The results show that 22 % of the respondents use PSSE for AIS, skepticism remains regarding the benefit of PSSE for AIS. Support for SRS funded research suggests belief that there is potential benefit from PSSE and the best way to assess that potential is through evidence development
