Billions of people are without access to surgical care, in part because of the inequitable distribution of the surgical workforce. Drawing on recently collected data for the number of surgeons, anaesthesiologists, and obstetricians worldwide, we sought to show their global maldistribution by identifying thresholds of surgical workforce densities, and by calculating the number of additional provide
Context: Long-term data are missing in GH-treated acute lymphoblastic leukemia (ALL) patients. GH therapy may result in poorer outcome regarding cardiovascular (CV) and particularly cardiac effects than in patients with hypothalamic-pituitary disease. Objective: Our objective was to evaluate GH therapy on CV risk, cardiac function, physical activity, and quality of life in ALL patients treated wit
Hepatitis A virus (HAV) was isolated from human faeces using a fetal rhesus monkey kidney cell line (Frhk-4). Infectious medium from passage 12 was used to inoculate a large (5000 cm2) microcarrier cell culture maintained in suspension. The microcarriers used were swollen, collagen-coated dextran beads on which it was easy to propagate Frhk-4 cells. Intra- and extra-cellular virus levels were assa
Pulmonary delivery of pharmaceutical aerosols can be quantified using gamma scintigraphy. Technetium-99m, the most commonly used radionuclide in scintigraphic studies, cannot be incorporated into the drug molecule and, therefore, may be distributed differently from the drug itself, particularly if the drug is presented as a solid in a liquid suspension or as a dry powder formulation. This study de
Infection with Trypanosoma cruzi causes megasyndromes of the gastrointestinal (GI) tract. We used magnetic resonance imaging (MRI) to monitor alterations in the GI tract of T. cruzi-infected mice, and to assess the role of nitric oxide (NO) in the development of intestinal dilation. Brazil strain-infected C57BL/6 wild-type (WT) mice exhibited dilatation of the intestines by 30 days post-infection.
BACKGROUND. Prostate-specific antigen (PSA) is produced in high amounts by normal and malignant prostate cancer cells. PSA is a serine protease with substrates that include semenogelin I and II, insulin-like growth factor binding protein 3, fibronectin, and laminin. PSA, via its enzymatic activity, may play a role in growth, invasion, and metastasis of prostate cancer cells. Recent data also sugge
Objective: The objective of this study was to compare the outcomes of antiretroviral therapy (ART) between hospital and health center levels in Ethiopia. METHODS: Medical records of 1709 ART patients followed for 24 months at 2 hospitals and 3 health centers in the Oromia region of Ethiopia were reviewed. Noted outcomes of ART were currently alive and on treatment; lost to follow-up (LTFU); transf
A role for Helicobacter pylori infection in the development of gastric cancer in humans is well established; however, evidence for its carcinogenicity in animals remains inadequate. Mongolian gerbils and mice are commonly used to investigate the carcinogenicity of H. pylori, yet it is unclear whether H. pylori infection per se causes gastric cancer or duodenal ulcers in these animal models. Gastri
IgG subclasses of glutamic acid decarboxylase (GAD(65)) antibodies (GADA) may reflect the immunological state in the pancreas of GADA-positive patients with autoimmune diabetes. The use of biotin-conjugated antibodies and streptavidin Sepharose are used commonly in immunoprecipitation assays (IPA) based on (125)I- or (35)S-labelled antigens to capture IgG subclasses directed against IA-2 or GAD(65
This is the final report of the project “Ascending evacuation in long stairways: Physical exertion, walking speed and behaviour”. This project investigated the effects of fatigue on walking speeds, physiological performance and behaviours in case of long ascending evacuation. The report includes a literature review on, at the time when the project began, existing material on ascending evacuation o
Liberalisation and deregulation of public utility sectors has been introduced in several European countries. In 1994 Swedish municipalities were instructed to reorganise waste collection routines by enlarging the number of fractions to be able to reuse waste fractions in an environmental benign way. The public waste sector have to a considerable extent been diversified and deregulated. At the same
Identification of novel biomarkers for early diagnosis, prognosis, and treatment decision will be instrumental for improving disease outcome for patients suffering from complex diseases, such as cancer and autoimmune disorders. Within personalized medicine, the use of circulating biomarkers will allow clinicians to tailor medical treatment based on individual characteristics of each patient, using
Human papillomaviruses (HPV) are epitheliotropic DNA tumor viruses that are prevalent in the human population. A subset of the HPVs termed high-risk HPVs (HR-HPVs) are causative agents of anogenital cancers and head-and-neck cancers. Cancer is the result of persistent high-risk HPV infections that have not been cleared by the immune system of the host. These infections are characterized by dysregu
Co-infections with bacterial or fungal pathogens could be associated with severity and outcome of disease in COVID-19 patients. We, therefore, used a 16S and ITS-based sequencing approach to assess the biomass and composition of the bacterial and fungal communities in endotracheal aspirates of intubated COVID-19 patients. Our method combines information on bacterial and fungal biomass with communi
A 67-year-old, previously fit, woman presented with a history of rectal bleeding.Per rectum examination revealed alow rectal mass, which on endoscopy wasdemonstrated to be submucosal. MR rectumconfirmed a 5 cm rectal mass displacing therectum anteriorly. Chest x-ray and abdominalCT did not reveal any metastatic disease. Biopsies were consistent with high grade gastrointestinal stromal cell tumour
