Aktuelle Herausforderungen in der Therapie des Typ-1-Diabetes beim Kind

Das 1921 entdeckte Insulin wurde 1922 erstmals als Therapie für Typ-1-Diabetes eingeführt. Hundert Jahre später wird es immer noch als einzige medikamentöse Behandlung eingesetzt. Die jüngsten Fortschritte haben zu einer erheblichen Optimierung der Stoffwechselkontrolle beigetragen. Einleitung Typ-1-Diabetes (T1D) ist eine der häufigsten chronischen Erkrankungen bei Kindern, mit einer jährlichen Inzidenzzunahme von 3% [1]. Die Ätiologie des T1D ist unbekannt, aber eine Dysregulation der Autoimmunität, dokumentiert durch die Zirkulation von Autoantikörpern, sowie eine genetische Prädisposition sind ursächlich beteiligt. Das Risiko, an T1D zu erkranken, beträgt bei Kindern 0,4%; gibt es bereits an T1D-erkrankte Familienangehörige, steigt das Risiko um das Zehnfache. Neueste Daten weisen auf einen deutlichen Anstieg der weltweiten Inzidenz während der Corona-Pandemie hin [2–5]. Ziel dieses Beitrags ist es, die neuesten Entwicklungen und aktuellen Herausforderungen bei der Behandlung des T1D bei Kindern darzustellen

On the phenomenological analyses of ss-sˉ{\bar s} asymmetry in the nucleon sea

Two phenomenological models which give opposite predictions for the $s$-${\bar s}$ asymmetry in the nucleon sea are re-analyzed carefully. It is pointed out that although the quantitative results in both models depend dramatically on the parameters, the predictions for the shape of $s(x)-{\bar s}(x)$ in the two models are parameter independent and opposite. Thereby the coming experiments are likely to be able to distinguish the two models. We find that the reason for the two models giving opposite predictions is that the fluctuation functions and parametrizations for the strange (anti-strange) quark distribution in the baryon (meson) in the two models are quite different. To further investigate these models, we use the same parametrizations for the strange (anti-strange) distributions of the baryon (meson) in the two models. We find that one of the models depends strongly on the parameter which controls the behavior of the meson-baryon fluctuation function. Also the two models agree on the shape and size of $s$-${\bar s}$ for some values of the model parameters, but can disagree strongly for others.Comment: RevTex, 11 pages, 7 Postscript figure

A comprehensive fracture prevention strategy in older adults: The European union geriatric medicine society (EUGMS) statement

Prevention of fragility fractures in older people has become a public health priority, although the most appropriate and cost-effective strategy remains unclear. In the present statement, the Interest group on falls and fracture prevention of the European union geriatric medicine society (EUGMS), in collaboration with the International association of gerontology and geriatrics for the European region (IAGG-ER), the European union of medical specialists (EUMS), the Fragility fracture network (FFN), the International osteoporosis foundation (IOF) – European society for clinical and economic aspects of osteoporosis and osteoarthritis (ECCEO), outlines its views on the main points in the current debate in relation to the primary and secondary prevention of falls, the diagnosis and treatment of bone fragility, and the place of combined falls and fracture liaison services for fracture prevention in older people

Evaluation of Effects of Two Spring Applications of Micronutrients on the Population Density of Common Pistachio Psylla (Agonoscena Pistaciae) in Pistachio Orchards

The common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Aphalaridae) is one of the most detrimental pests to pistachio trees. This pest is distributed throughout all the pistachio producing regions of Iran. Nowadays various pesticides are used to control the common pistachio psylla, but extensive pesticide spraying against this pest over a period of several years has overpowered its natural enemies. Moreover, the overlapping of generations has resulted in an abundant presence of the pest. Many herbivorous insects can make qualitative distinctions between host plants, they can feed and oviposit preferentially on higher quality plants. Cultural methods such as crop fertilization can affect the susceptibility of plants to insect pests by altering a plant tissue's nutrient level. This study tested nitrogen (N), calcium (Ca) and zinc (Zn) fertilizers on A. pistaciae in pistachio orchards. The experiment was based on complete randomized blocks with three replications and nine treatments including once-applied Zn, Ca, N, NCa, ZnCa, ZnN, ZnCaN, pesticide (amitraz) and a control (distilled water), on common pistachio psylla fed on 20-year-old pistachio trees of Ahmadaghaei rootstock. The results demonstrated that the effect of nutritional solutions on nymph and egg populations showed a significant difference at a 5% level. The highest measure of control on eggs was related to amitraz, ZnCa and Zn while the least was related to NZn. The results also showed that the highest measure of pest control was related to Ca while the least was related to N and Zn. The results indicated that combinations of the elements mentioned had a stronger reducing effect on the concentration of pistachio psylla nymphs than the effect pesticide had
