Rainer Wirth
The technique of percutaneous endoscopic gastrostomy (PEG) was introduced in 1979 as a semi-invasive approach for children with the need for a gastric fistula in order to avoid an operative intervention. The suture pull-through method was rapidly established and is now omnipresent. Because scientific evidence is broadly missing, there is some uncertainty about the indications in geriatric medicine. Guidelines do not recommend the insertion of a PEG in patients with severe dementia and malnutrition. Tube feeding is mainly recommended as a temporary method for patients who cannot take oral nutrition for more than 3 days or for whom the energy intake for more than 10 days presumably covers less than 50% of their needs, assuming that the overall prognosis is reasonable...

We summarize and numerically compare two approaches for modeling and simulating the dynamics of dry granular matter. The first one, the discrete-element method via penalty (DEM-P), is commonly used in the soft matter physics and geomechanics communities; it can be traced back to the work of Cundall and Strack [P. Cundall, Proc. Symp. ISRM, Nancy, France 1, 129 (1971); P. Cundall and O. Strack, Geotechnique 29, 47 (1979)GTNQA80016-850510.1680/geot.1979.29.1.47]. The second approach, the discrete-element method via complementarity (DEM-C), considers the grains perfectly rigid and enforces nonpenetration via complementarity conditions; it is commonly used in robotics and computer graphics applications and had two strong promoters in Moreau and Jean [J...

This single-arm, open-label, phase II study in 42 Japanese postmenopausal patients with estrogen receptor-positive/human epidermal growth factor receptor 2-negative (ER+/HER2-) advanced breast cancer evaluated the efficacy, safety, and pharmacokinetics of first-line palbociclib (125 mg once daily, 3 weeks on/1 week off) coadministered with letrozole (2.5 mg once daily). The primary endpoint of investigator-assessed 1-year progression-free survival probability was 75.0% (90% CI, 61.3%-84.4%), far surpassing the 40% lower limit of the 90% CI supporting efficacy...

This study examined the microbial diversity and community assembly of oral microbiota in periodontal health and disease and after nonsurgical periodontal treatment. The V4 region of 16S rRNA gene from DNA of 238 saliva and subgingival samples of 21 healthy and 48 diseased subjects was amplified and sequenced. Among 1979 OTUs identified, 28 were overabundant in diseased plaque. Six of these taxa were also overabundant in diseased saliva. Twelve OTUs were overabundant in healthy plaque. There was a trend for disease-associated taxa to decrease and health-associated taxa to increase after treatment with notable variations among individual sites...

Suicide data relating to 1979-2014 were obtained from three East Asian jurisdictions (Taiwan, Hong Kong, Japan) and two 'Western' countries (Australia, New Zealand). Rates and age patterns of suicide have changed markedly since 1979. Graphs of these patterns largely remained either upward-sloping, bimodal or flat (uniform) over the 36 years, male commonly differing from female, and East Asian patterns more like each other than those of the Western countries. Japan's male middle-aged suicide rate reached a peak in 1999-2003, which, like increased rates among working age males in Hong Kong and Taiwan, has been attributed largely to consequences of Asian financial crises...

Our retrospective study of burn patients presents a three-step treatment of heterotopic ossification: excision surgery, early rehabilitation, and analgesia. We included patients admitted to the department for treatment of postburn heterotopic ossification between January 1, 1979, and September 30, 2015. The mean age at the time of the burn was 43.3 years. Men accounted for the majority of burn patients who developed an osteoma (70.8%). The mean total skin area burned was 38.4%. No osteoma justifying surgery was found for any patient with a total burned skin area less than 19%...

Major and severe accidents have occurred three times in nuclear power plants (NPPs), at Three Mile Island (USA, 1979), Chernobyl (former USSR, 1986) and Fukushima (Japan, 2011). Research on the causes, dynamics, and consequences of these mishaps has been performed in a few laboratories worldwide in the last three decades. Common goals of such research activities are: the prevention of these kinds of accidents, both in existing and potential new nuclear power plants; the minimization of their eventual consequences; and ultimately, a full understanding of the real risks connected with NPPs...

Osteoarthritis of the first carpometacarpal joint (CMCJ1) is a common, painful condition with positive radiological findings in up to 32% of people over 50 years of age and up to 91% of people over 80 years of age. Currently, there is insufficient evidence to recommend one surgical treatment option over the others. We conducted a retrospective review of 77 patients treated for CMCJ1 osteoarthritis with plate arthrodesis between 1979 and 1996. The review included physical examination, including range of motion (ROM) of the thumb interphalangeal joint, metacarpophalangeal joint and CMCJ1, pinch grip, key grip and power grip strength, and a questionnaire on subjective outcomes (appearance, dexterity, load bearing, pain, strength, subjective overall result and if patients would choose the procedure again)...

Many species currently placed in Sciacharis Broun were once included in Euconnus Thomson, and their taxonomic history is complicated due to diffuse and overlapping diagnoses of both genera applied by previous authors, numerous virtually unjustified transfers of species between them, and hundreds of species not assigned to any subgenus. Based on comparative morphological studies of respective type species, we clarify the status of Allomaoria Franz, Austroconophron Franz, Magellanoconnus Franz, Neuraphoconnus Franz and Valdivioconnus Franz...

Chris Mol, Arie Querido and Piet Muntendam were three socially and politically active medical doctors in the 20th century. Inspired by different sources (Catholicism, and the social democratic and progressive-liberal movements), these doctors strove to improve public health in the Netherlands. Up to about 1940 they were primarily traditional doctors caring for individual patients. After World War Two their scope widened, eventually to the wider society. The life histories of the three main characters are remarkably intertwined...

Tonsillectomy is a major surgical procedure in terms of volume in the general otolaryngological practice. It is a 3000-year-old surgical operation, referred in Hindu medicine. There has been a conceptual change in the indications and surgical technique in the last 40 years. A comparative study between the various methods of tonsillectomy was done. The study was carried out in the single institutional set up by the same surgeon but using different techniques. The study aimed at comparing the intra-operative factors (blood loss, time taken for surgery), postoperative results (pain, bleeding, dehydration, time taken for complete healing), and other complications like vomiting and hospitalization time between different groups of surgical methods...

In recent times, inulinase has emerged as one the most prominent and industrially upcoming enzymes applied to meet the ever increasing demand of d-fructose and fructooligosaccharides (FOS) as sweetener and prebiotics in the food and pharmaceutical industry, respectively. This review deals with types of inulinase and the attempts made to modify it for better thermal stability and shelf life. The ease of immobilization of inulinase has led us to the path of experimenting with different methods of enzyme immobilization since 1979...
