1. 16. Urinary tract infections in primary health care in northern Sweden : epidemiological, bacteriological and clinical aspects

   Författare :Sven Ferry; Bengt Mattsson; Lars Burman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract infection UTI ; primary health care PHC ; epidemiology; clinical presentation; bacteriuria diagnosis; bacteriology; drug resistance; therapy;

   Sammanfattning : The epidemiology of urinary tract infection (UTI) in the population of Vännäs (8 000 inhabitants) was studied during one year. The annual incidence increased from 0.5% in the first decade of life to more than 10% in the age group 90-100 years. LÄS MER

3. 17. Wastewater discharges and microbial variability in a surface water source

   Författare :Johan Åström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; faecal indicators; pathogens; drinking-water; microbial risk assessment; variability; rainfall; catchment; wastewater; surface water; Hazardous events;

   Sammanfattning : Planning for drinking-water safety in surface waters includes a systematic assessment of hazards in the catchment, and microbial contamination is considered a major health risk. The aim of this thesis was to identify and characterize microbial hazardous events reported for River Göta älv, Sweden. LÄS MER

4. 18. Diet and gut microbiota in cardiometabolic health: Studies from the Danish Diet, Cancer and Health – Next Generations Cohort and the sub-cohort MAX

   Författare :Agnetha Rostgaard-Hansen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiometabolic diseases; reproducibility; nutrients; gut microbiota; food frequency questionnaire; risk factors; 24-hour dietary recall; epidemiology; temporal variation; dietary patterns; cohort study; validity;

   Sammanfattning : Cardiometabolic diseases (CMD) are the leading cause of death globally. Diet is a key preventive factor of CMD and a determinant of gut microbiota. Gut microbiota, diet and their interactions have been associated with CMD. In observational studies, diet is measured by self-reported instruments, that need to be validated before use. LÄS MER

5. 19. Microbiologic diagnostic tests when asymptomatic carriers are present. Aspects of the use of conventional throat and nasopharyngeal culture as examples

   Författare :Ronny K Gunnarsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carriage; respiratory tract infections; predictive value of tests; epidemiology; decision making; streptococcal infections; Streptococcus pyogenes; tonsillitis;

   Sammanfattning : Carriers of potentially pathogenic bacteria simultaneously ill from a viral infection complicatethe diagnostic procedure in respiratory tract infections. The present statistical methodsavailable to evaluate common diagnostic tests either ignore the phenomenon of carriers orprovide test characteristics that are difficult to apply in clinical decision making.

7. 20. Silicon Nanowire Based Sensors for Bacterial Tests

   Författare :Yingtao Yu; Zhen Zhang; Mihai Adrian Ionescu; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon nanowire; field-effect transistor; antibiotic susceptibility test; bacterial metabolism; nanoelectromechanical sensor; multiplexed detection;

   Sammanfattning : Rapid and reliable antibiotic susceptibility testing (AST) is urgently required to diagnose bacterial infectious diseases and avoid antibiotic misuse, providing valuable information on the efficacy of antibiotic agents and their dosages for treatment. However, the currently employed phenotypic ASTs normally demand the growth of bacteria into colonies, which usually takes more than two days. LÄS MER
