Abstract
Background/AimsOptic neuritis (ON) is the primary ophthalmic manifestation of myelin oligodendrocyte glycoprotein-IgG-associated disorder (MOGAD), but numerous reports have expanded the visual manifestations of this condition. The goal of this study was to synthesise the extensive literature on this topic to help ophthalmologists understand when testing for MOG-IgG should be considered.MethodA systematic review of the English-language literature was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searches were conducted using Ovid MEDLINE (from January 1, 1948 to April 1, 2020) and Ovid EMBASE (from January 1, 1947 to April 1, 2020). Inclusion criteria included studies describing non-isolated ON ophthalmic manifestations where cell-based assays were used for the detection of MOG antibodies.ResultsFifty-one articles representing 62 patients with a median age of 32.0 (range 2–65), female gender (51%) and follow-up of 20.0 months (range: 1–240) were included. Twenty-nine patients had non-isolated ON afferent visual manifestations: uveitis, peripheral ulcerative keratitis, acute macular neuroretinopathy, neuroretinitis, venous stasis retinopathy, large preretinal macular haemorrhage, orbital inflammatory syndrome, orbital apex syndrome, optic perineuritis, papilloedema and homonymous visual field defects. Incomplete recovery of ON was associated with a case of Leber’s hereditary optic neuropathy. Efferent ophthalmic manifestations included cranial neuropathies, internuclear ophthalmoplegia, central nystagmus, saccadic intrusions and ocular flutter. Cranial nerve involvement was secondary to enhancement of the cisternal portion or brainstem involvement. All included cases were treated with corticosteroids with 31% of cases requiring additional immunosuppressive therapy.ConclusionsMOGAD has been associated with various afferent and efferent ophthalmic manifestations apart from isolated ON. Awareness of these findings may result in earlier diagnosis and treatment.

Abstract
Background Guidelines based on patient preferences differ from those developed solely by clinicians and may promote patient adherence to guideline recommendations. There is scant evidence on how to develop patient-informed guidelines. This study aimed to describe how guideline developers identify, incorporate and report patient preferences. Methods We employed a descriptive cross-sectional survey design. Eligible organizations were non-profit agencies who developed at least one guideline in the past five years and had considered patient preferences in guideline development. We identified developers through the Guidelines International Network and publicly-available guideline repositories, administered the survey online, and used summary statistics to report results. Results The response rate was 18.3% (52/284). Respondents included professional societies, and government, academic, charitable and healthcare delivery organizations from 18 countries with at least 1 to ≥6 years of experience generating patient-informed guidelines. Organizations most frequently identified preferences through patient panelists (86.5%) and published research (84.6%). Most organizations (48, 92.3%) used multiple approaches to identify preferences (median 3, range 1 to 5). Most often, organizations used preferences to generate recommendations (82.7%) or establish guideline questions (73.1%). Few organizations explicitly reported preferences; instead, they implicitly embedded preferences in guideline recommendations (82.7%), questions (73.1%), or point-of-care communication tools (61.5%). Most developers had little capacity to generate patient-informed guidelines. Few offered training to patients (30.8%), or had dedicated funding (28.9%), managers (9.6%) or staff (9.6%). Respondents identified numerous barriers to identifying preferences. They also identified processes, resources and clinician- and patient-strategies that can facilitate the development of patient-informed guidelines. In contrast to identifying preferences, developers noted few approaches for, or barriers or facilitators of incorporating or reporting preferences. Conclusions Developers emphasized the need for knowledge on how to identify, incorporate and report patient preferences in guidelines. In particular, how to use patient preferences to formulate recommendations, and transparently report patient preferences and the influence of preferences on guidelines is unknown. Still, insights from responding developers may help others who may be struggling to generate guidelines informed by patient preferences.

Abstract
OBJECTIVES Cognitive intervention studies have reported improvements in various domains of cognition as well as a transfer effect of improved function post training. Despite the availability of web based cognitive training programs, most intervention studies have been performed under the supervision of researchers. Therefore, the purpose of this study was to first, examine the feasibility of a six week home based computerized cognitive training (CCT) program in a group of community dwelling older adults and, second, to determine if a CCT program which focused on set shifting, attention, and visual spatial ability impacted fall risk measure performance. DESIGN This pilot study used a pretest/posttest experimental design with randomization by testing site to an intervention or control group. PARTICIPANTS Community dwelling older adults (mean age = 74.6 years) participated in either the control (N=25) or the intervention group (N=19). INTERVENTION Intervention group subjects participated in 6 weeks of home based CCT 3x/week for an average of 23 minutes/session, using an online CCT program. MEASUREMENTS Comparisons of mean scores on three measures of physical function (usual gait speed, five times sit to stand, timed up and go) were completed at baseline and week 7. RESULTS Following the completion of an average of 18 sessions of CCT at home with good adherence (86%) and retention (92%) rates, a statistically significant difference in gait speed was found between groups with an average improvement of 0.14 m/s in the intervention group. CONCLUSION A home based CCT program is a feasible approach to targeting cognitive impairments known to influence fall risk and changes in gait in older adults.

Abstract
BACKGROUND In older adults declines in gait speed have been identified as predictors of functional decline and have been found in those with cognitive dysfunction. Cognitive training interventions that emphasize addressing executive function (EF) have resulted in a transfer effect from training cognitive processes into improved function. However research examining the effects of an EF specific computerized cognitive training (CCT) program on gait speed (GS) is limited. OBJECTIVES To compare the effects of a six week EF specific CCT program on GS in community dwelling older adults using a pretest/posttest experimental design with subgroup comparisons based on a cutoff GS of 1.0m/s. SETTING Home based. PARTICIPANTS Forty independent living older adults (>65 years) without diagnosed cognitive impairment participated in either the intervention or control groups. INTERVENTION A six week long progressively challenging EF focused CCT program was performed at home. MEASUREMENTS Demographic variables, cognitive function (Trail-Making Test Part B) and GS were measured at baseline at week 7. Between group comparisons were completed for the whole sample initially with subgroup comparisons performed based on participants' initial GS (Slow walkers: GS<1.0m/s; Fast Walkers: GS>1.0m/s). RESULTS No differences in GS were found for the whole population, but subgroup analyses restricted to slow walkers demonstrated a statistically significant improvement in GS after 6 weeks of CCT (µ =0.33 m/s, p = 0.03). Other outcomes measures were not statistically different at posttest. CONCLUSIONS Older adults who walk at speeds <1.0m/s may benefit from a progressively challenging CCT program when self-administered in the home.

Abstract
Resources for conserving biodiversity are invariably insufficient. This situation creates the need for transparent, systematic frameworks to help stakeholders prioritize the allocation of resources across multiple management actions. We developed a novel framework that explicitly prioritizes actions to minimize the impacts of several threats across a species' range. The framework uses a budget constraint and maximizes conservation outcomes from a set of management actions, accounting for the likelihood of the action being successfully applied and accepted by local and Indigenous communities. This approach is novel in that it integrates local knowledge and expert opinion with optimization software, thereby minimizing assumptions about likelihood of success of actions and their effectiveness. To test the framework, we used the eastern Gulf of Carpentaria and Torres Strait population of the flatback turtle, Natator depressus, as a case study. This approach allowed the framework to be applied in a data-poor context, a situation common in conservation planning. The framework identified the best set of actions to maximize the conservation of flatback eggs for scenarios with different budgets and management parameters and allowed comparisons between optimized and preselected scenarios. Optimized scenarios considered all implementable actions to explore how to best allocate resources with a specified budget and focus. Preselected scenarios were used to evaluate current allocations of funds and/or potential budget allocations suggested by different stakeholders. Scenarios that used a combination of aerial and ground strategies to reduce predation of eggs performed better than scenarios that focused only on reducing harvest of eggs. The performances of optimized and preselected scenarios were generally similar among scenarios that targeted similar threats. However, the cost-effectiveness of optimized scenarios was usually higher than that of preselected scenarios, demonstrating the value of conducting a systematic optimization approach. Our method provides a foundation for more effective conservation investments and guidance to prioritize actions within recovery plans while considering the sociopolitical and cultural context of decisions. The framework can be adapted easily to a wide range of species, geographical scales, and life stages.

Abstract
Behavioural treatment programmes have been shown repeatedly to be effective in alleviating dental anxiety but few studies have provided long-term follow-ups. In this study, dentally anxious Ss who had completed a 4-session behavioural group programme were followed up for periods between 1 and 4 years after successful completion of treatment. It was hypothesized that dental visit satisfaction would be associated with regular dental attendance. 88% of Ss contacted agreed to cooperate; of these, 70% were still maintaining regular check-ups. There were no differences between regular and irregular attenders in terms of age, gender, education, marital status, degree of pre-treatment avoidance or time elapsed since completion of the programme. However, Ss who did not see their dentists regularly were more likely to have shown higher levels of anxiety immediately after completing the programme, less concordance between the subjective and overt behavioural aspects of anxiety and to have experienced more invasive than non-invasive procedures than the others. It was argued that dentally anxious individuals are not a homogeneous group and that a better understanding of their individual differences would lead to the development of more efficacious treatment procedures.

Abstract
Thirty-nine hemodynamically stable trauma patients were evaluated prospectively by laparoscopy before planned celiotomy. Laparoscopy was performed using a forward-viewing laparoscope connected to two high-resolution video monitors. The mechanism of injury was blunt trauma in eight, stab wounds (SWs) in 16, and gunshot wounds (GSWs) in 15. Laparoscopy correctly identified the presence of an intraperitoneal injury in 26 patients. Six other patients had retroperitoneal injuries, five of which were seen on laparoscopy. The remaining seven patients had no demonstrable intraperitoneal or retroperitoneal injuries, did not undergo celiotomy, and were observed without morbidity. In comparison with findings at surgery, laparoscopy identified injuries to the liver in eight of ten, to the diaphragm in three of three, to the colon in two of three, to the stomach in three of three, to the kidney in one of one, to the spleen in none of three, and to the small bowel in none of four patients. Visualization of the spleen was achieved in only one patient. The extent of the hemoperitoneum was underestimated from the laparoscopic examination in all nine patients with greater than 750 mL of peritoneal blood, four of whom had undetected active bleeding. Laparoscopy was performed easily in all patients and there were no complications associated with its use. In conclusion, the absence of an intra-abdominal injury was correctly identified with laparoscopy in 11 patients and laparoscopy may decrease the need for celiotomy in selected patients. However, the inability to "run the small bowel," visualize the spleen, and evaluate hemorrhage limits the utility of laparoscopy in determining which patients with laparoscopically visualized injuries will require celiotomy.

Abstract
This article examines the recent decision of the Full Court of the Family Court in Re Marion dealing with the question of sterilisation of intellectually disabled minors and in particular, the question of whether a parent or guardian can lawfully consent to a sterilisation operation upon an intellectually disabled minor or whether court approval is required before such an operation can lawfully be performed. The article goes on to critically examine legislation in force in various Australian jurisdictions concerning involuntary sterilisations and substituted consent as well as legislative reforms that have been proposed in this area.

Abstract
For the development of multilayer fluorescent immunoassays to determine directly a variety of therapeutic drugs high specific monoclonal antibodies against the anticonvulsants carbamazepine, phenobarbital, phenytoin and valproic acid have been prepared. For each antibody a standard curve could be established showing good linearity and a suitable sensitivity scope. To validate the eligibility of the desired antibodies a variety of drugs and metabolites sharing structural similarities to the individual drugs were tested for their cross-reactivity. It could be shown that only a few very closely related compounds exhibited substantial cross-reactivity. These monoclonal antibodies are therefore assumed to be suitable for a TDM-assay development.
