Physiological Factors Related to Aspiration Risk: A Systematic Review
Dysphagia, 2014Co-Authors: Catriona M. Steele, Julie A. Y. CicheroAbstract:Penetration–aspiration is considered the most serious component of oropharyngeal dysphagia. Clinicians regularly evaluate the pathophysiology of swallowing and postulate reasons or mechanisms behind penetration–aspiration. In this article we share the results of a two-stage literature review designed to elucidate the association between abnormalities in Physiological measures of swallowing function and the occurrence of penetration–aspiration. In the first stage, a broad scoping review was undertaken using search terms for nine different structures involved in oropharyngeal swallowing. In the second stage, based on the results of the initial search, a more focused systematic review was undertaken which explored the association between aspiration and abnormalities in respiratory, tongue, hyoid, and laryngeal function in swallowing. A total of 37 articles underwent detailed quality review and data extraction in the systematic review. The results support measurement of tongue strength, anatomically normalized measures of hyoid movement, bolus dwell time in the pharynx while the larynx remains open, respiratory rate, and respiratory swallow phasing as parameters relevant to aspiration risk.

the influence of environmental and Physiological Factors on the litter size of wild boar sus scrofa in an agriculture dominated area in germany
Science of The Total Environment, 2016Co-Authors: Magali Frauendorf, Friederike Gethoffer, Ursula Siebert, Oliver KeulingAbstract:The wild boar population has increased enormously in all of Europe over the last decades and caused problems like crop damage, transmission of diseases, and vehicle accidents. Therefore, it is necessary to investigate the underlying causes of this increase in order to be able to manage populations effectively. The purpose of this study was to analyse how environmental (food and climate) and Physiological Factors (maternal weight and age) as well as hunting and population density influence the litter size of wild boar populations in Northern Germany. The mean litter size in the studied population for the whole period was 6.6 (range 1–12), which is one of the highest in all of Europe. Litter size was positively influenced by maternal body weight, higher mast yield of oak as well as higher temperature in combination with higher precipitation in summer. Only higher temperature or only higher precipitation in summer however had a negative effect on litter size production. Probably, weather and food conditions act via maternal body weight on the litter size variation in wild boar. Hunting as well as population density did not affect the litter size variation in this study which might indicate that wild boar population did not reach carrying capacity yet.

Physiological Factors and medications as predictors of injurious falls by elderly people a prospective population based study
Age and Ageing, 1996Co-Authors: Keijo Koski, Heikki Luukinen, Pekka Laippala, Sirkkaliisa KivelaAbstract:To determine the Physiological Factors and medications predicting injurious falls among the elderly population, the authors conducted a prospective study in a rural home-dwelling population aged 70 years or over, initially 979 persons (377 men and 602 women), from 1 January 1991 to 31 December 1992, in Northern Finland. The independent risk Factors for all falling injuries, falls leading to minor injuries and ones leading to major injuries were determined. In men, the independent risk Factors for all injuries were gait disturbances odds ratio (OR) = 3.5 and the use of digitalis (OR = 2.2), those for minor injuries were gait disturbances (OR = 2.7) and the use of calcium blockers (OR = 3.0), and those for major injuries were the absence of a quadriceps reflex (OR = 4.8), gait disturbances (OR = 2.8) and the use of digitalis (OR = 2.9). In women, the corresponding independent risk Factors were short step length (OR = 32.1), the use of calcium blockers (OR = 2.5) and the use of medications for improving peripheral circulation (OR = 3.7) for all injurious falls, path deviation (OR = 2.3) the use of calcium blockers (OR = 2.8) and the use of anti-inflammatory drugs (OR = 2.1) for minor injuries, and foot deformity (OR = 2.0), short step length (OR = 15.8), the use of long-acting benzodiazepines (OR = 4.0) and the use of calcium blockers (OR = 2.4) for major injuries. In order to prevent injurious falls, attention should be given to the prescription of tranquillizers, cardiovascular medications and anti-inflammatory drugs. The walking abilities of elderly people should be maintained and chronic diseases leading to peripheral neuropathy should be treated adequately. Language: en
