RESUMO
BACKGROUND: The aim of this study was to evaluate ultrasound as a routinely used procedure and extended physical examination in geriatric patients in acute care. METHODS: Prospective study of 86 patients using ultrasound as a screening examination (abdomen, basal sections of the thorax, thyroid glands) under comparative use of a hand-held ultrasound device (HHUSD) and a high-end ultrasound (HEUSâ¯= gold standard). RESULTS: In 20/86 (23.2%) clinically relevant findings with therapeutic consequences were found (pleural effusion, urinary retention, choledocholithiasis metatases, colon tumor). In 22/86 (25.6%) patients, additional questions existed besides the screening indication: tumor search (9.3%), anemia (5.8%), liver value elevation (5.8%), dyspnea (5.8%), splenic pathologies (2.3%), weight loss (1.2%), infectious focus (1.2%), diarrhea (1.2%), intra-abdominal hematoma (1.1%), abdominal aortic aneurysm (1.2%). The most common sonographic findings included: cholecystolithiasis (32.6%); right pleural effusion (31.4%), thyroid nodules (30.2%), renal cysts (27.9%), and fatty liver (26.7%). There were significant differences in sizing between HHUSD and HEUS (kidneys, pancreatic corpus and pancreatic caudal diameters, portal vein, left hepatic vein) without diagnostic relevance. CONCLUSION: The extended screening by ultrasound provided important answers to classical questions in geriatrics (e.g. urinary retention, volume deficiency/pleural effusion) in many cases. The new findings had therapeutic consequences in one fifth of the patients. The HHUSD can be used in screening.

BACKGROUND: Lack of clinical management of old patients in the emergency department. QUESTION: How can we manage old patients in the emergency department more effectively, medically and economically? METHODS: Evaluation of current selection and screening methods and recommendations for old patients in the emergency department. Acute inpatient treatment needs, presence of dysfunction in at least two core areas and assessment of advance care needs are examined. RESULT: The identification of old patients in the emergency department as geriatric patients alone shows no control potential. Combining the three test criteria of acute inpatient need for treatment, the presence of dysfunction in at least two core areas and the assessment of advance care needs generates four old patient types that have interesting control potential: the medical traumatology patient, the acute geriatric patient, the rehabilitative geriatric patient, and the ambulatory patient. DISCUSSION: in addition to identifying geriatric patients, screening should map acute inpatient treatment needs, assessment of dysfunction, and analysis of advance care needs to define clinically steerable old patients.

The number of older patients admitted to emergency departments (ED) increases continuously. The Identification of Seniors at Risk (ISAR) score is currently recommended to screen patients in German ED, but its appropriateness is being criticized. ISAR scores and clinical characteristics from 98 emergency admissions (EA), 80 from acute geriatrics (AG) and 89 from a geriatric rehabilitation (GR) unit were compared retrospectively. No significant differences were found between groups, being the ISAR score positive in 87.7% of EA, 94.9% of AG and 94.4% of GR cases. None of positively identified geriatric patients in the EA was transferred to the geriatric ward of competence. EA patients showed significantly higher number of functional impairments (p = 0.001) and higher BI score (p < 0.0001) compared to AG and GR groups. A higher ISAR score threshold and additional functional information might be needed to better select patients in need of prompt treatment by a geriatric team.

OBJECTIVE: To compare the efficacy of desmopressin and placebo in independent geriatric outpatients with nocturnal polyuria (NP). METHODS: A prospective, randomized, single-center, national, double blind, placebo-controlled, fixed-dose, parallel group comparative trial was carried out. The study included 110 geriatric outpatients, 55 patients per treatment group using desmopressin acetate nasal spray (strength: 0.1â¯mg/ml) once daily of 10⯵g/spray blast or placebo. MEASUREMENT: The NP positive geriatric outpatients with >33% nocturnal urine output volume, antidiuretic hormone (ADH) positive or negative were treated over 10 days with intranasal spray in the evening time (7 p.m.), drug or placebo. On day 1 voiding frequency, voiding volumes day and night, serum osmolarity and arginine-vasopressin (AVP) were measured at 7 p.m. On days 2, 5 and 10 creatinine, blood urea nitrogen (bun), blood count and Creactive protein (CrP), vena cava diameter and bioimpedance were measured and a structured interview was implemented (voiding frequency, sleeping behavior and subjective and cognitive behavior). RESULTS: The NP patients showed a mean night voiding volume of 50.60%, 39.21% (nâ¯= 102) showed a low AVP level at baseline with no correlation to sodium concentration or voiding frequencies. The primary efficacy criterion, a decrease of the nocturnal voiding frequency during the course of the clinical trial as change from baseline at day 10 (visit 4) was 50% versus 41.40% in the verum versus placebo group, respectively but the differences were not significant. The Utest showed superiority of AVP-positive NP patients to a positive reaction on desmopressin. Sleeping time hours increased in both groups without significant differences. CONCLUSION: In this 10-day clinical trial desmopressin was not proven to be therapeutically superior to placebo with respect to micturition frequency or sleeping hours. Independent geriatric outpatients with decreased ADH levels seemed to respond and benefit from active treatment with desmopressin. The unexpected results in the placebo group may be due to the effect of intensive outpatient care and information on NP outpatients with normal AVP levels.

The number of older people with polypharmacy (more than six drugs taken simultaneously) is increasing. The greatest proportion consists of guideline drugs, analgesics and psychopharmaceuticals because in many cases of geriatric multimorbidity several underlying main diseases are present which must be treated according to the guidelines. Polypharmacy is a complex and difficult situation for all treating physicians because substantial side effects and intoxication can be induced but it can also be very difficult to recognize which drug was at fault and how a reduction can be safely made. This article describes the exemplary case of a 77-year-old patient with drug-induced delirium and demonstrates the procedure followed. The question of rapid assistance by the utilization of medication data bases is described and the importance of clinical pharmacists is demonstrated. In the future working with medication data bases will possibly become increasingly more important for physicians and hopefully simpler. The case presented here also shows that the effective and justified reduction of drugs can show a very good effect and is possible.

A case study of an 89-year-old patient is reported, who was admitted to hospital because of immobility due to pain. After the cause of the pain could initially be clarified and treated, the further clinical course in this very old woman showed an alarming symptom complex of agitation, confusion and cognitive deterioration, which took on grave forms. The work-up of this case showed a typical constellation of pain and depression in old age; however, the pharmaceutical treatment in this case is not atypical and could lead to a severe serotonin syndrome. The interaction, diagnostics, differential diagnosis, pharmacological, functional, codification and economic aspects of the course of the disease are discussed.

Greenland's bed topography is a primary control on ice flow, grounding line migration, calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates the penetration of warm Atlantic water (AW) that rapidly melts and undercuts Greenland's marine-terminating glaciers. Here we present a new compilation of Greenland bed topography that assimilates seafloor bathymetry and ice thickness data through a mass conservation approach. A new 150 m horizontal resolution bed topography/bathymetric map of Greenland is constructed with seamless transitions at the ice/ocean interface, yielding major improvements over previous data sets, particularly in the marine-terminating sectors of northwest and southeast Greenland. Our map reveals that the total sea level potential of the Greenland ice sheet is 7.42 ± 0.05 m, which is 7 cm greater than previous estimates. Furthermore, it explains recent calving front response of numerous outlet glaciers and reveals new pathways by which AW can access glaciers with marine-based basins, thereby highlighting sectors of Greenland that are most vulnerable to future oceanic forcing.
RESUMO
BACKGROUND: Demographic changes have resulted in an increase in the number of older (> 75 years) multimorbid patients in clinics. In addition to the primary acute diagnoses that lead to hospitalization, this group of patients often has cognitive dysfunctions, such as delirium. According to clinical experience, delirium patients are more time-consuming for clinicians and their function is often poor. The costs caused by delirium patients are currently unknown. In the present study, a retrospective examination of a database was carried out to calculate the costs that arise during the clinical treatment of documented delirium patients. SETTING AND METHODS: The purpose of this retrospective analysis was to collect information recorded by nursing personnel trained in the treatment of delirium and information from a manual documentation matrix for additional time expenditure. In the database analysis anonymous data of previously discharged patients for a time window of 3 months were analyzed. Documented additional expenditure for patients with hyperactive delirium at hospitalization were analyzed by personnel. Material costs, the duration of hospitalization by main diagnosis and age clusters during hospitalization until discharge were also examined. The analysis was performed in a hospital with internal wards. RESULTS: Data for 82 hyperactive delirium patients were examined and an average of approximately 240 min of additional personnel expenditure for these patients was found. These patients were approximately 10 years older (p < 0.01) and were hospitalized for an average of 4.2 days longer (p < 0.01) than non-delirium patients. Hyperactive delirium usually developed within the first 5 days of hospitalization and lasted 1.6 days on average. Patients for whom hyperactive delirium was detected early were hospitalized for significantly less time than those for whom it was detected late (6.85 versus 13.61 days, p = 0.002). Additionally, calculated personnel and material costs, including costs affecting the hospitalization period, amounted to approximately 1200 per hyperactive delirium patient. This corresponds to approximately 0.3 CMP (casemix points) per patient. CONCLUSION: The calculations of personnel and material costs and duration of hospitalization in patients with hyperactive delirium demonstrated significant additional costs. Early routine detection of delirium can be achieved through training and this approach leads to a shortening of the hospitalization period and lower costs.

The Mw 8.8 megathrust earthquake that occurred on 27 February 2010 offshore the Maule region of central Chile triggered a destructive tsunami. Whether the earthquake rupture extended to the shallow part of the plate boundary near the trench remains controversial. The up-dip limit of rupture during large subduction zone earthquakes has important implications for tsunami generation and for the rheological behavior of the sedimentary prism in accretionary margins. However, in general, the slip models derived from tsunami wave modeling and seismological data are poorly constrained by direct seafloor geodetic observations. We difference swath bathymetric data acquired across the trench in 2008, 2011 and 2012 and find ~3-5 m of uplift of the seafloor landward of the deformation front, at the eastern edge of the trench. Modeling suggests this is compatible with slip extending seaward, at least, to within ~6 km of the deformation front. After the Mw 9.0 Tohoku-oki earthquake, this result for the Maule earthquake represents only the second time that repeated bathymetric data has been used to detect the deformation following megathrust earthquakes, providing methodological guidelines for this relatively inexpensive way of obtaining seafloor geodetic data across subduction zone.
RESUMO
Nutritional intake is often compromised in elderly, multimorbid patients. Enteral nutrition (EN) by means of oral nutritional supplements (ONS) and tube feeding (TF) offers the possibility to increase or to insure nutrient intake in case of insufficient oral food intake. The present guideline is intended to give evidence-based recommendations for the use of ONS and TF in geriatric patients. It was developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. The guideline was discussed and accepted in a consensus conference. EN by means of ONS is recommended for geriatric patients at nutritional risk, in case of multimorbidity and frailty, and following orthopaedic-surgical procedures. In elderly people at risk of undernutrition ONS improve nutritional status and reduce mortality. After orthopaedic-surgery ONS reduce unfavourable outcome. TF is clearly indicated in patients with neurologic dysphagia. In contrast, TF is not indicated in final disease states, including final dementia, and in order to facilitate patient care. Altogether, it is strongly recommended not to wait until severe undernutrition has developed, but to start EN therapy early, as soon as a nutritional risk becomes apparent.

Cyclophosphamide (CP) and Ifosfamide (IF) are of great importance in the therapy of neuroblastoma (NB). They are prodrugs which have to be activated by microsomes in order to become active compounds. We established a test system which allowed the activation of CP and IF by liver microsomes in the presence of NB cells. The data from these experiments showed that neuroblastoma cells (SK-N-SH, SK-N-LO and IMR-5) were unable to activate CP and IF, but in the presence of rat liver microsomes considerable cytotoxicity was achieved, similar to those of the preactivated derivatives maphosphamide (MP) and 4-hydroxy-ifosfamide (4-OH-IF). Compared to other compounds the final metabolite acrolein contributes significantly to the cytotoxicity of CP and IF, obviously through significant lowering of the glutathione levels in the cells. The incubation system as described allows the rapid determination of the cytotoxicity of CP and IF in the simultaneous presence of microsomes. The results show great differences in the sensibility of NB cells toCP and IF.
