BACKGROUND: Long-term cognitive problems are common among elderly patients after surgery, and it has been suggested that inhalation anaesthetics play a role in the development of dementia. This study aims to investigate the hypothesis that patients with dementia have been more exposed to surgery and inhalational anaesthetics than individuals without dementia.METHODS: Using 457 cases from a dementi
This article discusses the violations committed by every party in the civilian war in Yemen, because there is no any accountability from the international community against those who committed these crimes.
The 1930s, characterised by repercussions from World War I and the Great Depression, was an era of populism, nationalism, protectionism, government intervention and attempts to create planned economies. The perceived need for economic planning emerged in Sweden in part due to the increasing political strength of the Social Democrats and their evolution from a party hampered by Marxist fatalism to
ABSTRACT In a patient with advanced Hodgkin's disease (HD) associated with generalized pruritus, an unexpected relief of itching was found to be an early sign of spinal cord compression. Following irradiation of an extradural mass at the Th II level, itching recurred. Although the mechanisms bringing about itching in HD are unknown, the relief and recurrence of the symptom in our patient are in li
A standardized personal interview schedule was used to study occupational exposure to organic solvents among 25 men aged 20-65 a with Hodgkin's disease and 50 referents matched for sex, age and residence. When exposure was defined as the handling of organic solvents every workday for at least 1 a within the 10-a period immediately preceding the interview, 12 of the Hodgkin's disease patients (48%)
In a consecutive series of 150 women with breast cancer 122 had borne one or more children. Sixty-two patients were aged below 55 years at diagnosis (group A) and 60 were 55 years or older (group B). In group A 91 out of 153 children (59%) were boys compared with 48 out of 141 (34%) in group B (p=0 000007). In group A 54 of the 62 patients (87%) had given birth to one or more boys compared with 35
In this thesis, we draw inspiration from both classical system identification and modern machine learning in order to solve estimation problems for real-world, physical systems. The main approach to estimation and learning adopted is optimization based. Concepts such as regularization will be utilized for encoding of prior knowledge and basis-function expansions will be used to add nonlinear model
ABSTRACT. Using a standardized interview schedule, occupational exposure to organic solvents was investigated in 61 consecutive male patients with the diagnosis of non‐Hodgkin's lymphoma. When exposure was defined as handling of organic solvents every working day for at least one year, 23 patients were exposed and 38 non‐exposed. Of 15 patients with clinical stage I‐II above the diaphragm, 12 (80%
In vitro uptake of tritiated thymidine was studied in autoradiographic preparations of lymphoma cell suspensions obtained through fine-needle aspiration biopsy from 28 patients with non-Hodgkin's lymphoma. The labelling indices (LI ) were highest in patients with histiocytic or poorly differentiated lymphocytic lymphoma. During a two-year period there was a significant correlation between LI and s
A method for chromosome analysis of malignant cells by means of fine needle aspiration biopsy has been developed. The method has some obvious advantages compared to conventional surgical biopsy. During a 1-year period 25 consecutive non-Hodgkin, non-Burkitt lymphoma biopsies from 19 patients have been studied. In 14 out of 21 lymph node biopsies chromosome analysis was successful; whereas, four bi
By microcalorimetry the metabolic activity of malignant cells from 21 patients with non‐Hodgkin lymphoma was monitored. Heat production, a measure of the metabolic activity of cells, showed positive correlation with the clinical‐course of the disease. The heat produced by tumor cells from patients with progressive disease was 5.5 pW/cell, while that from patients responding to treatment was 3.1 pW
Five different human malignant melanoma were heterotransplanted subcutaneously to nude mice. When small tissue pieces were used 3 out of 5 tumors grew. Subcutaneous injections of suspended tumor cells were also made, but all failed to take. Metastatic or infiltrative growth was never seen in the mice observed for up to 2.5 months. The successful grafts largely retained the original morphological f
