- Various approaches to the study of differential gene expression are applied to compare cell lines and tissue samples in a wide range of biological contexts. The compromise between focusing on only the important genes in certain cellular processes and achieving a complete picture is critical for the selection of strategy. We demonstrate how global microarray technology can be used for the exploration of the differentially expressed genes extracted through representational difference analysis (RDA). The subtraction of ubiquitous gene fragments from the two samples was demonstrated using cDNA microarrays including more than 32 000 spotted, PCR-amplified human clones. Hybridizations indicated the expression of 9100 of the microarray elements in a macrophage/foam cell atherosclerosis model system, of which many were removed during the RDA process. The stepwise subtraction procedure was demonstrated to yield an efficient enrichment of gene fragments overrepresented in either sample (18% in the representations, 86% after the first subtraction, and 88% after the second subtraction), many of which were impossible to detect in the starting material. Interestingly, the method allowed for the observation of the differential expression of several members of the low-abundant nuclear receptor gene family. We also observed a certain background level in the difference products of nondifferentially expressed gene fragments, warranting a verification strategy for selected candidate genes. The differential expression of several genes was verified by real-time PCR.

Tidskriftsartikel (refereegranskat)abstract
- Objective To explore in a primary care setting the associations between patients' daily self-measured blood pressure (BP) during eight weeks and concurrent self-reported values of wellbeing, lifestyle, symptoms, and medication intake. We also explore these associations for men and women separately. Design and setting The study is a secondary post-hoc analysis of the randomised controlled trial PERson-centeredness in Hypertension management using Information Technology (PERHIT). The trial was conducted in primary health care in four regions in Southern Sweden. Patients Participants (n = 454) in the intervention group in the PERHIT-trial used an interactive web-based system for self-management of hypertension for eight consecutive weeks. Each evening, participants reported in the system their wellbeing, lifestyle, symptoms, and medication adherence as well as their self-measured BP and heart rate. Main outcome measures Association between self-reported BP and 10 self-report lifestyle-related variables. Results Self-reported less stress and higher wellbeing were similarly associated with BP, with 1.0 mmHg lower systolic BP and 0.6/0.4 mmHg lower diastolic BP (p < 0.001). Adherence to medication had the greatest impact on BP levels (5.2/2.6 mmHg, p < 0.001). Restlessness and headache were also significantly associated with BP, but to a lesser extent. Physical activity was only significantly associated with BP levels for men, but not for women. Conclusion In hypertension management, it may be important to identify patients with high-stress levels and low wellbeing. The association between medication intake and BP was obvious, thus stressing the importance of medication adherence for patients with hypertension.

- OBJECTIVES: To increase the proportion of individuals with hypertension obtaining a blood pressure (BP) of less than 140/90 mmHg by improving the management of hypertension in daily life from a person-centred perspective. METHODS: In this unblinded randomized controlled trial, we tested an interactive web-based self-management system for hypertension. A total of 949 patients with hypertension from 31 primary healthcare centres (PHCCs) in Sweden were randomized 1 : 1 to either the intervention or usual care group. The intervention included daily measurement - via the participant's mobile phone - of BP and pulse and reports of well being, symptoms, lifestyle, medication intake and side effects for eight consecutive weeks. It also included reminders and optional motivational messages. The primary outcome was the proportion of participants obtaining BP of less than 140/90 mmHg at 8 weeks and 12 months. Significance was tested by Pearson's chi 2 -test. RESULTS: A total of 862 patients completed the trial, 442 in the intervention group and 420 in the control group. The primary outcome (BP <140/90 mmHg) at 8 weeks was achieved by 48.8% in the intervention group and 39.9% in the control group ( P = 0.006). At 12 months, 47.1% (intervention) and 41.0% (control group) had a BP less than 140/90 mmHg ( P = 0.071). CONCLUSION: The proportion of participants with a controlled BP of less than 140/90 mmHg increased after using the interactive system for self-management of hypertension for 8 weeks compared with usual care. Although the trend continued, there was no significant difference after 12 months. The results indicate that the effect of the intervention is significant, but the long-term effect is uncertain. TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov (NCT03554382).

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- OBJECTIVE: Few studies address results from use of new technology and patient participation in hypertension management. The PERHIT Study is a multicentre randomised controlled trial with the aim to evaluate the effects of a person-centred approach using a web-based, interactive self-management system through the patient´s own mobile phone on blood-pressure and well-being. Primary aim is the degree of achieved blood pressure (BP) control after eight weeks and one year. In addition, person-centeredness, usefulness, daily life activities in relation to BP values, awareness of risk and health care costs are studied. DESIGN AND METHOD: The PERHIT study was performed in four regions in southern Sweden. Following inclusion, more than 900 patients from 31 primary health care centres were randomised to two groups. In the intervention group (INT), patients were provided with a web-based self-management support system including a home-BP monitor. For eight consecutive weeks, they measured BP and performed self-reports regarding well-being, symptoms, lifestyle, medication intake and side effects every evening via their mobile phone. They could also receive motivational messages and reminders throughout the intervention period. Both patients and professionals had access to graphic feedback of reported values through a secure web portal. Patients in the control (CON) group received standard treatment as usual. RESULTS: The primary outcome (BP < 140/90 mmHg) was achieved by 48.5% and 47.1% in the INT, and by 40.4% and 40.9% in the CON group after 8 weeks (p = 0.016) and 12 months (p = 0.067), respectively. Both patients and professionals experienced the system as a useful resource for communication regarding BP and lifestyle. They described that it could be used to support a constructive and person-centred partnership between patients and professionals. CONCLUSIONS: Blood pressure control was significantly better after eight weeks, but not after one year, following an intervention based on use of mobile phones, feedback and interaction between patients and primary care professionals compared to standard care. The system can be a tool toward a new way of working and help patients reach a controlled BP and play a role in a more person-centred and individually adapted hypertension management.

- Blood pressure variability (BPV) represents a cardiovascular risk factor, regardless of mean level of blood pressure (BP). In this post-hoc analysis from the PERson-centredness in Hypertension management using Information Technology (PERHIT) study, we aimed to explore BPV in daily home measurements in hypertensive patients from primary care, to identify factors associated with high BPV and to investigate whether estimated glomerular filtration rate (eGFR) and pulse pressure, as markers of target organ damage (TOD), are associated with BPV. For eight consecutive weeks, 454 participants reported their daily BP and heart rate in their mobile phone, along with reports of lifestyle and hypertension-related factors. Systolic BP (SBP) values were used to calculate BPV with coefficient of variation (CV) as primary estimate. Background characteristics and self-reports were tested between fifths of CV in a linear regression model, adjusted for age and sex. Associations between BPV and eGFR and pulse pressure were tested with linear and logistic regression models. Higher home BPV was associated with higher age, BP, heart rate, and smoking. BPV was lower for participants with low alcohol consumption and treatment with calcium channel blockers. There was a significant association between BPV and pulse pressure (P = 0.015), and between BPV and eGFR (P = 0.049). Participants with high BPV reported more dizziness and palpitations. In conclusion, pulse pressure and eGFR were significantly associated with home BPV. Older age, high BP, heart rate, and smoking were associated with high BPV, but treatment with calcium channel blockers and low alcohol consumption was associated with low BPV. Trial registration: The study was registered with ClinicalTrials.gov [NCT03554382].

Tidskriftsartikel (refereegranskat)abstract
- During the last decades of the 19th century Sweden changed from being a developing to a developed country. It was a period when many people emigrated to America and Denmark, due to miserable times. The aim was to investigate the status and development of the public health in the eastern part of the province Skane, Sweden, during the years 1860 to 1899. The investigation included a study of differences in health between city and countryside, men and women, and health problems now and then. The official reports of provincial doctors (general practitioners) from Brosarp (1860-1899) and city doctors from Kristianstad (1883-1899) were studied. The reports included conscription reports, tables of illnesses and deaths, and an annually summarized health report of the district. The district of Brosarp was a very poor area, due to its topographical location. The poverty brought illness, but not as much as could be expected. The infant mortality rate was lower than for the rest of the country. The long distances between the villages impeded the transmission of infectious diseases. The health situation in Kristianstad was also affected by its topographical location. The humid and densely populated city was a hotbed for infections. Sanitary improvements in both Brosarp and Kristianstad resulted in a better health situation at the end of the 19th century. There were several similarities between the studied areas and the developing countries of today, for example regarding malnutrition, traditional medicine and problems with contaminated drinking water. Compared to the health problems of today, poverty and infectious diseases were greater problems during the studied period of time, while problems related to diet and alcohol drinking were similar. More research is needed to relate the public health in Brosarp and Kristianstad to that in other Swedish districts during the same period of time.

- Altered lipid metabolism and extensive lipid storage in cells have been associated with various medical disorders, including cancer. The development of fluorescent probes that specifically accumulate in lipid deposits is therefore of great interest in order to study pathological processes that are linked to dysregulated lipogenesis. In the present study, we present a small fluorescent benzothiadiazole dye that specifically stains lipid droplets in living and fixated cells. The photophysical characterization of the probe revealed strong solvatochromic behavior, large Stokes shifts, and high fluorescent quantum yields in hydrophobic solvents. In addition, the fluorophore exhibits a nontoxic profile and a high signal-to-noise ratio in cells (i.e., lipid droplets vs cytosol), which make it an excellent candidate for studying lipid biology using confocal fluorescent microscopy.
