I dagens samhälle tillbringar människan ca 90 procent av sin tid inomhus, vilket innebär att människan befinner sig i konstgjort inomhusklimat. Då människan tenderar att befinna sig inomhus är det stor vikt att ventilationen ska fungera så bra som möjligt och att inomhusklimatet är tillfredsställande för vårt välmående och välbefinnande på arbetsplatsen. Tidigare studier visar att nästan hälften av svenskar är missnöjda med ventilationen i deras arbetsmiljö (kontor). Ett bra inomhusklimat i kontorsmiljöer ökar tillfredställandet hos personalen, ökar produktiviteten samt minskar sjukfrånvaron. Detta leder till att organisationen/företaget besparar pengar i slutändan, då personalen arbetar mer effektivt och har mindre sjukfrånvaro. Syftet med denna studie är att undersöka klimatet i kontorsmiljön med fokus på termisk komfort samt se hur ventilation systemen påverkar inomhusklimatet. Vidare kommer sambanden mellan dessa att analyseras. Målet är undersöka hur komforten på kontoret påverkar människors hälsa, produktivitet och välmående. Målet är även att identifiera om det råder bristfällig ventilation samt att presentera eventuella förbättringar. I studien genomförs en undersökning av sex kontor på Brinellvägen 23. I undersökningen tillämpas en enkätstudie och ett antal olika mätningar, flödesmätningar, koldioxidsmätningar, temperaturmätningar och den relativa fuktigheten. I flödesmätningarna mäts till – och frånluften på samtliga kontor. Medan koldioxidmätningarna mäter även temperaturen och relativa fuktigheten. Koldioxidsmätningarna pågick i två timmar i 4 kontor, medan i de två resterande kontoren fortsatte mätningarna under en hel arbetsdag. Enkätstudien tilldelades ut till personalen i kontoren i syfte att ta del av subjektiva åsikter kring miljön i kontoren. Resultaten från mätningarna och enkätundersökningen visar att klimatet i kontoren i överlag inte var tillfredställande och obehag upplevdes utav personerna som arbetar där. Endast ett kontor uppfyllde det projekterade tilluftsflödet, medan de resterande kontoren varken uppfyllde projekterade flödena eller BBR:s krav för mängden flöde i kontorsmiljöer. Koldioxidhalten i kontoren med en person klarade av gränsen under 1000 ppm. Dock är kontoren projekterade för två personer och när två personer arbetade i kontoren översteg koldioxidhalten till ca 1200 ppm. Då koldioxidhalten överstiger 1000 ppm bör ventilationen kontrolleras, vilket behövs i detta fall. In today's society, humans spend about 90 percent of their time indoors, in an artificial indoor climate. As people tend to be indoors more and more, it is important that the ventilation work as well and efficiently as possible, and that the indoor climate is pleasing for our well-being at the workplace. Previous studies show that almost half of Swedes are dissatisfied with the ventilation in their work environment (offices). A good indoor climate in offices increases employee satisfaction, increases productivity, and reduces absenteeism. This causes the organization / company to save money in the end, as staff work more efficiently and have less sick leave. The purpose of this study is to investigate the climate in office environment, focusing on thermal comfort and to see how ventilation systems affect the indoor climate. Furthermore, the relationships between these will be analyzed. The aim is to investigate how the comfort in the office affects human health, productivity and well-being. The goal is also to identify if there is insufficient ventilation to the offices that will be investigated and to eventually present possible improvements. In this report a study of six offices on Brinellvägen 23 was carried out. In the study, a number of flow measurements are carried out for each office's supply and exhaust air, carbon dioxide measurements, temperature and the relative humidity for four hours in four of the offices, with open and closed doors. While in two of the offices, the measurements continued for a whole working day, 6-8h. In addition to these measurements, surveys were distributed to the staff in the offices in order to share subjective opinions about the environment in the offices. The results from the measurements and the survey showed that the overall climate was not satisfactory, and discomfort was experienced by the people working there. Only one office met the projected supply airflow, while the remaining offices neither met the projected flows nor BBR requirements for the amount of flow in office environments. The carbon dioxide levels in the offices with one person was acceptable, they did not pass the limit of 1000 ppm. However, the offices were projected for two persons and when two persons worked in the offices, the carbon dioxide levels exceeded about 1200 ppm. When the carbon dioxide level exceeds 1000 ppm, it is recommended that the ventilation be checked, as needed in this case.

Abstract Background Intravascular fasciitis (IVF) is a rare benign condition characterised by reactive myofibroblastic proliferation arising from the superficial or deep fascia and involving arteries and/or veins. It is a distinct variant of the more common condition of nodular fasciitis, which possesses similar clinical and histological features to IVF, but lacks vascular invasion. A thorough review of the literature revealed 26 reported cases of IVF. Case presentation We report a case of IVF in a 16-week pregnant lady affecting the hypothenar eminence of the hand associated with the ulnar artery. Conclusion The characteristic involvement of muscular arteries and veins by reactive myofibroblastic proliferation in IVF suggests a malignant component and often leads to an inappropriate diagnosis for this benign condition. We propose that hormone-related changes associated with pregnancy may play an important role in the aetiopathogenesis of this myofibroblastic lesion.

Diabetes is a major disease condition that is accountable for 5% of annual cause of death globally and it continues to escalate. In this research the levels of minerals in persons with type 2 diabetes were investigated using hair as the biopsy specimen. The philosophy behind is that minerals are involved in countless metabolic functions in all phases of the life process, an imbalance of which can have widespread implication, while hair due to its physiology serves an invaluable record of the body’s exposure to minerals. Hair metal testing is a fascinating new diagnostic tool and often gives unexpected clues to mineral imbalances in the body. In executing the research samples of head hair collected from 6 type 2 diabetic patients were washed to remove exogenous contaminants, then subjected to open vessel acid digestion and subsequent analysis for the elements Ca, Cd, Cr, Cu Fe, K, Mg, Na and Zn using Flame Atomic Absorption Spectroscopy (FLAAS). After comparing the concentration of the elements to a range that is considered to be normal it was found that Ca, Zn, Fe, Mg, K, Cu, Cd and Cr were off range while Na was normal. Upon investigating the function and effects of the elements that were off range it was found that a deficiency of chromium and an excess of iron could be a possible cause of diabetes.

- Abstract
Aims To provide insight into the mechanism of sudden adult death syndrome (SADS) and to give new clinical guidelines for the cardiac management of patients with the most common mitochondrial DNA mutation, m.3243A>G. These studies were initiated after two young, asymptomatic adults harbouring the m.3243A>G mutation died suddenly and unexpectedly. The m.3243A>G mutation is present in ~1 in 400 of the population, although the recognized incidence of mitochondrial DNA (mtDNA) disease is ~1 in 5000. Methods and results Pathological studies including histochemistry and molecular genetic analyses performed on various post-mortem samples including cardiac tissues (atrium and ventricles) showed marked respiratory chain deficiency and high levels of the m.3243A>G mutation. Systematic review of cause of death in our m.3243A>G patient cohort showed the persontime incidence rate of sudden adult death is 2.4 per 1000 person-years. A further six cases of sudden death among extended family members have been identified from interrogation of family pedigrees. Conclusion Our findings suggest that SADS is an important cause of death in patients with m.3243A>G and likely to be due to widespread respiratory chain deficiency in cardiac muscle. The involvement of asymptomatic relatives highlights the importance of family tracing in patients with m.3243A>G and the need for specific cardiac arrhythmia surveillance in the management of this common genetic disease. In addition, these findings have prompted the derivation of cardiac guidelines specific to patients with m.3243A>G-related mitochondrial disease. Finally, due to the prevalence of this mtDNA point mutation, we recommend inclusion of testing for m.3243A>G mutations in the genetic autopsy of all unexplained cases of SADS. [ABSTRACT FROM AUTHOR]

These studies were initiated after two young, asymptomatic adults harbouring the m.3243A>G mutation died suddenly and unexpectedly. The m.3243A>G mutation is present in ∼1 in 400 of the population, although the recognized incidence of mitochondrial DNA (mtDNA) disease is ∼1 in 5000., Methods and Results: Pathological studies including histochemistry and molecular genetic analyses performed on various post-mortem samples including cardiac tissues (atrium and ventricles) showed marked respiratory chain deficiency and high levels of the m.3243A>G mutation. Systematic review of cause of death in our m.3243A>G patient cohort showed the person-time incidence rate of sudden adult death is 2.4 per 1000 person-years.
