ABSTRACT

Falls are a major public health concern in the older population, and certain medication classes are a significant risk factor for falls. However, knowledge is lacking among both physicians and older people, including caregivers, concerning the role of medication as a risk factor. In the present statement, the European Geriatric Medicine Society (EuGMS) Task and Finish group on fall-risk-increasing drugs (FRIDs), in collaboration with the EuGMS Special Interest group on Pharmacology and the European Union of Medical Specialists (UEMS) Geriatric Medicine Section, outlines its position regarding knowledge dissemination on medication-related falls in older people across Europe. The EuGMS Task and Finish group is developing educational materials to facilitate knowledge dissemination for healthcare professionals and older people. In addition, steps in primary prevention through judicious prescribing, deprescribing of FRIDs (withdrawal and dose reduction), and gaps in current research are outlined in this position paper.

ABSTRACT

Several fly species have distinctly red-coloured eyes, meaning that the screening pigments that provide a restricted angular sensitivity of the photoreceptors may perform poorly in the longer wavelength range. The functional reasons for the red transparency and possible negative visual effects of the spectral properties of the eye-colouring screening pigments are discussed within the context of the photochemistry, arrestin binding and turnover of the visual pigments located in the various photoreceptor types. A phylogenetic survey of the spectral properties of the main photoreceptors of the Diptera indicates that the transition of the brown eye colour of the Nematocera and lower Brachycera to a much redder eye colour of the higher Brachycera occurred around the emergence of the Tabanidae family.

ABSTRACT

Introduction: Causes of hyponatraemia in older patients are multivariate and in the case of SIADH may often be drug induced. Diagnostic and treatment algorithms are unclear for this important age group. Methods: The author group identified 6 broad themes for consensus and formulated 42 separate consensus statements within these 6 themes. Statements were then circulated to geriatricians, general practitioners and other doctors to test agreement at the European level. Results: 64 responses were evaluated from around Europe. Agreement was achieved in 86% of the statements following amendment and redistribution of 6 of the statements. The survey and its feedback prompted the development of 13 recommendations related to the diagnosis and treatment of hyponatraemia including SIADH. Conclusion: The series of 13 recommendations developed here is intended to increase clarity for clinicians managing older patients with hyponatraemia and SIADH. Surprisingly, despite the lack of clear guidelines or recommendations for this age group consensus levels for the author-based statements were high among the respondents.

ABSTRACT

The facet lenses of the compound eyes of long-legged flies (Dolichopodidae) feature a striking, interlaced coloration pattern, existing of alternating rows of green-yellow and orange-red reflecting facets, due to dielectric multilayers located distally in the facet lenses (Bernard and Miller. Invest Ophthalmol 7:416-434 (1968). We investigated this phenomenon in the dolichopodid Dolichopus nitidus by applying microspectrophotometry, electron microscopy and optical modeling. The measured narrow-band reflectance spectra, peaking at ~540 and ~590 nm with bandwidth ~105 nm, are well explained by a refractive index oscillating sinusoidally in six periods around a mean value of about 1.44 with amplitude 0.6. The facet lens reflectance spectra are associated with a spectrally restricted, reduced transmittance, which causes modified spectral sensitivities of the underlying photoreceptors. Based on the modeling and electroretinography of the dolichopodid Condylostylus japonicus we conjecture that the green and orange facets narrow the spectral bandwidths of blue and green central photoreceptors, respectively, thus possibly improving color and/or polarization vision.

ABSTRACT

BACKGROUND: Multimorbidity and polypharmacy are threats to elderly patients; improvement of medication is important and a novel listing approach (the FORTA list) should support this in clinical practice. Here we aim to describe procedural details of successful application of FORTA. FORTA labels range from A (indispensable), B (beneficial), C (questionable) to D (avoid), depending on evidence for safety, efficacy and overall age-appropriateness. As implicit tool it is only applicable if medical details of the patient are known; the drug selection process and secondary assessments are compiled into a manual for successful, embedded use of FORTA. DISCUSSION: A flow chart is developed for the complex process of medication in the elderly starting from history taking and diagnostic assessment including disease grading. This is the base for FORTA-assisted selection of drugs to avoid overtreatment (drug not necessary), undertreatment (condition not or not sufficiently treated by positively labeled drugs) or mistreatment (drugs indicated, but negatively rather than positively labeled drug chosen). Selection is followed by secondary analyses, e. g. regarding contraindications (e. g. allergies), former drug responses, interactions, route of application, duration and dosing (e. g. renal adaptation). This may lead to iterative process optimization. The medication scheme is updated in reflection of clinical effects (e. g. blood pressure) and side effects (e. g. dizziness). CONCLUSION: The FORTA approach as an implicit tool should be embedded into the diagnostic and therapeutic workup of elderly patients and can give pivotal hints for the choice of medications; however it should not be seen as an isolated instrument.

ABSTRACT

Non-opioid analgesics are frequently used to control chronic pain in elderly patients; however some of these drugs show high rates of adverse drug reactions. Among these are significant clinical problems which impede an effective and safe pain control. This review provides recent data concerning non-steroidal anti-inflammatory drugs (NSAID), acetaminophen, metamizol and flupirtin. Due to their risk profile NSAIDs are less appropriate due to high incidence rates and drug-related risk patterns. Acetaminophen, metamizol and flupirtin may be recommended instead; however a shortcoming of acetaminophen in comparison to NSAIDs is its weaker action to control pain. Metamizol is still banned in some countries due to rare but potentially severe hematological side effects and flupirtin frequently causes unfavorable sedation.

ABSTRACT

Patients with impaired renal function are exposed to an increased risk for bleeding complications depending on the amount of the anticoagulant eliminated by the kidneys. The elimination of unfractionated heparins, vitamin K antagonists and argatroban is only minimally influenced by a reduced renal function. Low-molecular weight heparins, fondaparinux, danaparoid, hirudins and nonvitamin K antagonist oral anticoagulants (NOAC) cause a variably increased bleeding risk in renal impairment. Dose reductions are recommended for all of these anticoagulants in renal impairment, some are even contraindicated at certain levels of renal impairment. Their benefit over the conventional anticoagulants is preserved if renal dosing is employed. For end-stage renal disease patients specific treatment regimens are required.

ABSTRACT

The present position paper summarises the outcomes of an expert panel discussion held by hospital-based and office-based physicians with ample experience in the treatment of geriatric patients. The optimal approach to stroke prevention in geriatric patients with atrial fibrillation (AF) has not been adequately clarified. Despite their high risk of stroke and clear indication for anticoagulation according to established risk scores, in practice geriatric AF patients often are withheld treatment because of comorbidities and comedications, concerns about low treatment adherence or fear of bleeding events, in particular due to falls. The panel agreed that geriatric patients should receive oral anticoagulation as a rule, unless a comprehensive neurological and geriatric assessment (including clinical examination, gait tests and validated instruments such as Modified Rankin Scale, Mini-mental state examination or Timed Test of Money Counting) provides sound reasons for refraining from treatment. All patients with a history of falls should be thoroughly evaluated for further evaluation of the causes. Patients with CHADS2 score ≥ 2 should receive anticoagulation even if at high risk for falls. The novel oral anticoagulants (NOAC) facilitate management in the geriatric population with AF (no INR monitoring needed, easier bridging during interventions) and have, based on available data, an improved benefit-risk ratio compared to vitamin K antagonists. Drugs with predominantly non-renal elimination are safer in geriatric patients and should be preferred.
