Acute changes of systemic parameters in tumour-bearing rats, and of tumour glucose, lactate, and ATP levels upon local hyperthermia and/or hyperglyca…
1991
Arterial blood pressure and relevant parameters of the arterial blood (O2 and CO2 tensions, pH, haematocrit, serum electrolytes and osmolality) were determined in tumour-bearing rats upon local hyperthermia (HT) and/or hyperglycaemia (HG). Tumour heating was performed in a saline bath (44 degrees C) for 120 min; hyperglycaemia was induced by i.v. infusion of 40% glucose solution for 150 min [blood glucose levels: 35-40 mM during heating; total amount of glucose: 1.19 g/100 g body wt.; infusion rates: 0.31 ml (100 g body wt.)-1 min-1 for 2 min, 0.02 ml (100 g body wt.)-1 min-1 for 88 min, and 0.01 ml (100 g body wt.)-1 min-1 for 60 min]. Immediately after treatment, glucose, lactate and ATP …
Laser Doppler flux and tissue oxygenation of experimental tumours upon local hyperthermia and/or hyperglycaemia
1992
Laser Doppler fluxmetry and oxygen partial pressure (pO2) histography have been applied to investigate the acute effects of hyperthermia (HT) and/or hyperglycaemia (HG) on microcirculatory function and tissue oxygenation of subcutaneous rat tumours growing on the dorsum of the hind foot. The experiments were performed to test whether, and to what extent, the two adjunct treatment modalities applied alone or in combination can modify these therapeutically relevant parameters. Local HT was performed in a saline bath (44 degrees C) for 2 h; HG was induced by i.v. infusion of 40% glucose solution for 2.5 h (blood glucose levels: 35-40 mM during heating). Laser Doppler flux (LDF) in superficial …
Comparison between rectal and body surface temperature in dogs by the calibrated infrared thermometer
2020
Highlights • Dogs poorly tolerate rectal temperature measurements with a contact thermometer. • Existing alternative approaches used uncalibrated infrared thermometers. • Gum and inguinal temperature are correlated moderately to rectal temperature. • Hyperthermia was detected with sensitivity and specificity up to 90.0% and 78.6%. • Future studies should include a calibrated thermometer and control external factors.
EURECCA colorectal: multidisciplinary management: European consensus conference colon & rectum.
2014
Contains fulltext : 137861.pdf (Publisher’s version ) (Closed access) BACKGROUND: Care for patients with colon and rectal cancer has improved in the last 20years; however considerable variation still exists in cancer management and outcome between European countries. Large variation is also apparent between national guidelines and patterns of cancer care in Europe. Therefore, EURECCA, which is the acronym of European Registration of Cancer Care, is aiming at defining core treatment strategies and developing a European audit structure in order to improve the quality of care for all patients with colon and rectal cancer. In December 2012, the first multidisciplinary consensus conference about…
HIPEC for gynaecological malignancies: A last update (Review)
2023
Advanced-stage gynaecological cancer represents a clinical entity with challenging surgical treatment in an effort to optimize prognosis. Hyperthermic intraperitoneal chemotherapy (HIPEC) following cytoreductive surgery (CRS) has been reported as a method potentially eligible to improve prognosis. However, no definitive conclusions have yet been made on which types of cancer and which context HIPEC may actually have a beneficial impact. The present review discusses the efficacy and safety of HIPEC as a treatment option for patients with primary/recurrent ovarian, endometrial and cervix cancer, as well as peritoneal sarcomatosis. A literature search was conducted using MeSH terms for each top…
Tumorregression maligner Aderhautmelanome nach Transpupillarer Thermotherapie (TTT) versus Ruthenium-Brachytherapie und Sandwichtherapie – eine vergl…
2010
PURPOSE: The aim of this study was to evaluate tumour regression in a large series of choroidal melanomas, which were treated with three different eye-sparing treatment modalities. PATIENTS AND METHODS: Retrospective review of the treatment results in all eyes with malignant choroidal melanoma, which were treated in the University Eye Clinic of Mainz consecutively in the time span 1.1992 to 12.2000 with transpupillary thermotherapy (TTT, standard protocol Oosterhuis JA 1995), ruthenium brachytherapy (RB, tumor apex dose 150 Gy) or sandwich therapy (ST). One-step ST was defined as TTT followed by RB with 100 Gy tumor apex dose within 48 hours. The treatment of residual prominences with TTT s…
The prognostic value of skeletal muscle index on clinical and survival outcomes after cytoreduction and HIPEC for peritoneal metastases from colorect…
2021
BACKGROUND Cytoreductive surgery (CRS) and hypertermic intraperitoneal chemotherapy (HIPEC) represent the most effective strategy to manage peritoneal metastases (PM). This systematic review and meta-analysis aimed to assess the impact of body composition on clinical outcomes in patients with PM. METHODS A systematic literature search was performed using Medline, Web of Science and EMBASE databases from inception to the 20st August 2020. Data were independently extracted by 3 authors. Newcastle-Ottawa Scale was used to assess quality and risk of bias of studies. Pooled analyses were performed using Mantel-Haenszel method to estimate overall effect size with mean differences or odd ratios (O…
From putative genes to temperament and culture: Cultural characteristics of the distribution of dominant affective temperaments in national studies
2010
Abstract Background Affective temperaments may carry distinct evolutionary advantages both on the individual or a group level, so we can expect that in different cultural and national samples the frequency of dominant affective temperaments will show characteristic differences. The aim of the present study was to investigate the characteristics of distribution of dominant affective temperaments in different national studies of general non-clinical population. Method In our study we included six studies published in different countries around the world (Argentina, Germany, Hungary, Korea, Portugal, and Lebanon) which investigated a large sample of non-clinical population using TEMPS-A, and r…
Der Schlaganfall als medizinischer Notfall
1999
Studies into the pathophysiology of acute ischaemic stroke have indicated that treatment options are likely to be optimised when early signs of stroke are recognised and treatment is initiated within 3 hours from symptom onset. For most patients there is a long delay between the onset of symptoms and the start of therapy. Many factors are responsible for this time delay: signs and symptoms often go unrecognised by patients, relatives and bystanders and stroke is not given a high priority by medical staff. Although a small number of stroke patients is treated as emergency and attended to by the emergency medical services within this time window, this number could easily be increased by inten…
Did the ancient crenarchaeal viruses from the dawn of life survive exceptionally well the eons of meteorite bombardment?
2009
The viruses of Crenarchaeota are unexpectedly diverse in their morphologies, and most have no, or few, genes related to bacterial, eukaryal, euryarchaeal, or other crenarchaeal viruses. Though several different virus morphotypes have been discovered in enrichment cultures of microbial communities collected from geothermally heated environments around the world, the origins of such differences are unknown. We present a model that combines consideration of Earth's geological history, the early emergence of hyperthermophiles, and the early formation of viruses from primordial genes with the intent to explain this vast diversity of crenarchaeal viruses. Several meteorite- or flood basalt-induce…
