Hippocampal volume is a promising biomarker to enhance the accuracy of the diagnosis of dementia due to Alzheimer's disease (AD). However, whereas hippocampal volume is well studied in patient samples from clinical trials, its value in clinical routine patient care is still rather unclear. The aim of the present study, therefore, was to evaluate fully automated atlas-based hippocampal volumetry for detection of AD in the setting of a secondary care expert memory clinic for outpatients. One-hundred consecutive patients with memory complaints were clinically evaluated and categorized into three diagnostic groups: AD, intermediate AD, and non-AD. A software tool based on open source software (Statistical Parametric Mapping SPM8) was employed for fully automated tissue segmentation and stereotactical normalization of high-resolution three-dimensional T1-weighted magnetic resonance images. Predefined standard masks were used for computation of grey matter volume of the left and right hippocampus which then was scaled to the patient's total grey matter volume. The right hippocampal volume provided an area under the receiver operating characteristic curve of 84% for detection of AD patients in the whole sample. This indicates that fully automated MR-based hippocampal volumetry fulfills the requirements for a relevant core feasible biomarker for detection of AD in everyday patient care in a secondary care memory clinic for outpatients. The software used in the present study has been made freely available as an SPM8 toolbox. It is robust and fast so that it is easily integrated into routine workflow.

IntroductionResearch by AOTrauma’s orthogeriatrics education taskforce identified ongoing educational needs for surgeons and trainees worldwide regarding the medical management of older adults with a fracture. To address practicing surgeons’ preference for increased use of mobile learning, a point-of-care educational app was planned by a committee of experienced faculty. The goals were to deliver the app to surgeons, trainees, and other healthcare professionals, to measure usage, and to evaluate the impact on patient care.Materials and methodsThe committee of geriatricians and surgeons designed and developed four modules on osteoporosis, delirium, anticoagulation, and pain based on published evidence and the content was programmed into mobile app formats. A registration form was integrated and a 14-question online evaluation survey was administered to users.ResultsThe AOTrauma Orthogeriatrics app was installed by 17,839 users worldwide between September 2014 and October 2015: Android smartphones (44 %), iPhones (32 %), iPads (15 %), Android tablets (9 %). 920 users registered and 100 completed the online evaluation: orthopedic/trauma surgeons (67 %), residents/fellows (20 %), and other professionals (13 %). Ratings for all aspects were 4 or higher on a 1–5 Likert scale (5 = Excellent). 80 % of evaluation respondents found the answer to their question or educational need on their last visit, and 26 of 55 respondents (47 %) reported making a change in an aspect of their management of patients as a result of their learning from the app.ConclusionThe orthogeriatrics app reached its intended audiences and was rated highly as a method of providing education to help improve patient care. Content input by experienced faculty and app improvements based on user feedback were key contributors to successful implementation.

We confirm for seniors living in the community that women have a higher risk of hip fracture than men. However, among institutionalized seniors, men are at higher risk for hip fracture.

The multidimensional geriatric assessment is an interdisciplinary diagnostic process, taking into account several health dimensions. The resulting know-ledge is used to establish a treatment plan. The multidimensional geriatric assessment has shown its efficacy in the acute care treatment of multidimensionally ill and polymorbid patients in acute geriatric structures. The multidimensional geriatric assessment plays a central role in questions regarding the allocation of resources and is becoming more important because of the demographic development and the rapidly changing framework in our health system. It ensures that older patients don't slip through the net in a more fragmented clinical medicine. Growing evidence allows using this assessment approach in polymorbid patients being treated in specialised fields as traumatology, cardiology, oncology and nephrology.

For a comprehensive risk assessment in geriatric patients, the organ-specific risk stratification is insufficient. Assessment instruments that reflect the idiosyncrasies of multidimensional disease in geriatric patients can complement risk stratification. These should include the assessment of multimorbidity, frailty, nutrition, activities of daily living, and cognition. In addition to risk prediction, geriatric assessment has the major advantage of providing both a diagnostic and a planning perspective. This allows the implementation of supporting measures for optimal perioperative care, which is the goal of any risk stratification. Risk scores provide a global assessment, but they have their limitations in predicting individual patient risk.
