Optimal savings and health spending over the life cycle
2010
This paper investigates the relationship between saving and health spending in a two-period overlapping generations economy. Individuals work in the first period of life and live in retirement in old age. Health spending is an activity that increases quality of life and longevity. Empirical evidence shows that both health spending and saving behave as luxury goods but their behaviour differs markedly according to the level of per capita GDP. The share of saving on GDP has a concave shape with respect to per capita GDP, whereas the share of health spending on GDP increases more than proportionally with respect to per capita GDP. The ratio of saving to spending is nonlinear with respect to in…
Treatment of clinically localized renal tumors in the elderly
2011
There are several options for treating clinically localized renal tumors in the elderly, ranging from active surveillance to radical nephrectomy. Reduced renal function is associated with increased cardiovascular mortality, so maintaining renal function is of the utmost importance. Personalized therapy should be based on tumor location, comorbidities and general health status rather than tumor size and patient age.
Newborn infants and the moral significance of intellectual disabilities.
2001
This article presents moral philosophical arguments regarding life-saving medical treatment that may be more available to infants without disabilities than to infants with intellectual disabilities. The ideas are that children with disabilities are a burden to their families and to society and that a happy life may not be attainable for these children and their families. I argue that human well-being is not based merely on individual characteristics, but is a result of the individual's relation to other people. Further, children with disabilities are not inevitably a burden to their families or society. Accordingly, intellectual disability is not a sufficient reason for withholding life-sa…

Free Flaps for Anterior Chest Wall Reconstruction
2020
Reconstruction of full-thickness chest wall defects usually entails the use of regional pedicled myocutaneous flaps as first-choice option. As defect complexity increases and local options are not available, microsurgical reconstruction is required to transfer reliable and well-vascularized tissues from distant sites. Size, anatomic location, presence of dead spaces, and extent of eventual bone defect should be assessed for proper selection of the flap. Regional recipient vessels should be previously identified and checked in order to consider alternatively the need of extension of distant recipient vessels through arteriovenous (AV) loops or vein graft interposition.
Transpupillare Thermotherapie (TTT) zur Behandlung von Aderhautmetastasen
2001
Die transpupillare Thermotherapie (TTT) wird erfolgreich zur Behandlung kleiner Aderhautmelanome am hinteren Augenpol eingesetzt [9, 13, 14]. Wir berichten uber die erfolgreiche Behandlung von Aderhautmetastasen mittels TTT unter intravenoser Gabe von Indozyaningrun (ICG). Bei 3 Patienten mit systemisch metastasierenden Karzinomen (Osophagus-, Bronchial- und Mamma-Ca) wurden Aderhautfiliae in 4 Augen mit jeweils einer Sitzung TTT behandelt. Verwendet wurde ein Diodenlaser (810 nm) und Spotgrose 2–3 mm. Die Laserleistung (im Mittel 0,75W) wurde beginnend bei 0,3W in 50 mW Schritten fur jeweils 1 Minute erhoht, bis die Tumoroberflache eine grauweise Odembildung zeigte. Jeweils 1 Minute nach T…
Eye fluke-induced cataract formation in fish: quantitative analysis using an ophthalmological microscope
2004
We examined the parasite-induced cataract formation in rainbow trout (Oncorhynchus mykiss) using slit-lamp microscopy to determine the relationship between cataract intensity and number of Diplostomum spathaceum parasites that were established in the lens. Cataract intensity increased significantly with parasite burden, but was also affected by the pattern of exposure to the parasite cercariae. The slit-lamp methodology proved useful in scoring the cataracts since it provides a 3-dimensional view into the lens and gives an actual picture of the location and intensity of the cataracts, which allows detailed investigations of mechanisms underlying cataract formation in various fish species. P…
Reliability and validity of a new accelerometer-based device for detecting physical activities and energy expenditure.
2018
Background Objective assessments of sedentary behavior and physical activity (PA) by using accelerometer-based wearable devices are ever expanding, given their importance in the global context of health maintenance. This study aimed to determine the reliability and validity of a new accelerometer-based analyzer (Fibion) for detecting different PAs and estimating energy expenditure (EE) during a simulated free-living day. Methods The study consisted of two parts: a reliability (n = 18) and a validity (n = 19) test. Reliability was assessed by a 45 min protocol of repeated sitting, standing, and walking (i.e., 3 × 15 min, repeated twice), using both Fibion and ActiGraph. Validity was assesse…
Dilation of the ductus venosus by stent implantation increases placental blood perfusion in fetal sheep.
2006
The reduction of resistance to flow in the ductus venous (DV) and a decrease of blood supply to the liver serve for the survival of the fetus during hypoxia. The present study investigated the influence of the increased diameter of the DV on placental blood perfusion.In 15 ewes with twin pregnancies at gestational ages of 117 +/- 4 days, a stent (4 or 5 mm) was placed into the DV of 1 twin (DV(stent) group) under ultrasound guidance. Blood flow rates in the umbilical vein (UV) and DV of both fetuses were measured using Doppler ultrasound. Eight pairs of twin fetuses were included for the final analysis.The dilatation of the DV increased the blood flow volume rate passed through the DV from …
Residual coronary stenosis after thrombolysis with rt-PA or streptokinase: acute results and 3 weeks follow-up
1987
Ninety-one patients with acute myocardial infarction were assigned to intravenous treatment with streptokinase or rt-PA as part of the randomized trial carried out by the European Study Group for Recombinant Tissue-Type Plasminogen Activator (rt-PA). A patent coronary artery was found in 37 of 45 (82%) patients treated with rt-PA and in 27 of 46 (59%) patients treated with streptokinase 75-90 minutes after start of infusion. Patients were subsequently anticoagulated with heparin or dicoumarol up to a repeat angiography 3 weeks after the infarction. Of the 64 patients with successful reperfusion, 3 died and 3 suffered reocclusion of the vessel. Quantitative analysis of the coronary stenosis …
