Abstract
Abstract
Background/Introduction
Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors reduce low density lipoprotein cholesterol (LDL-C) levels by around 50% to 60%, and the risk of cardiovascular events in patients with atherosclerotic cardiovascular disease (ASCVD) in randomized clinical trials. Data on LDL-C reduction with PCSK9 inhibitors and its use in clinical practice is lacking.
Purpose
Assess LDL-C reduction with the PCSK9 inhibitor evolocumab and its use in clinical practice in Sweden.
Methods
Population-based, retrospective, longitudinal, observational study of patients initiating evolocumab treatment between July 2015 and May 2020. Patients undergoing lipoprotein apheresis were excluded. Patient level data was obtained from national diagnosis and pharmaceutical registers (covering 100% of the Swedish population), and electronic health records (covering 60% of the Swedish population). The use of evolocumab was assessed based on persistence with and adherence to treatment. Patients were defined as being persistent if they were still taking evolocumab 12 months after treatment initiation. Medication gaps were allowed until a last gap of ≥56 days. Patients were defined as being adherent if the proportion of days covered (PDC) by the drug was ≥80% during that same period. Mean LDL-C reduction was estimated 3 months after evolocumab treatment initiation, using a Generalized Least Squares regression model.
Results
Overall, 2341 patients were included in the analysis, with a median follow-up of 376 days. Median age was 65 years, 43% were women, 79% had a history of ASCVD and, among them, 94% had had a coronary event and 24% had diabetes. 44% of the patients had LDL-C available. Median LDL-C was 4.1 mmol/L and 64% of the patients were receiving oral lipid-lowering treatment (LLT). After 12 months of treatment, 76% of the patients were persistent with evolocumab. In these patients, median PDC over 12 months was 93%, with 86% of these patients being adherent (PDC ≥80%). In the overall population (n=724), the estimated mean LDL-C reduction with evolocumab at 3 months was 48% (2.1 mmol/L, from 4.4 mmol/L at baseline). In patients who were adherent to evolocumab during the first 6 months (n=567), LDL-C reduction was 53% (2.2 mmol/L, from 4.3 mmol/L at baseline) (see figure). In patients who were adherent to both evolocumab and oral LLT (PDC ≥80% over a period of 3 months before and after evolocumab initiation) (n=186), LDL-C reduction was 59% (2.1 mmol/L, from 3.6 mmol/L at baseline). The estimated mean LDL-C reduction remained stable over a 6-month period.
Conclusions
Persistence with and adherence to evolocumab treatment were high over 12 months. LDL-C reduction with evolocumab in clinical practice was similar to that observed in randomized clinical trials and remained stable over 6 months. At evolocumab treatment initiation, many patients had high LDL-C levels and underused oral LLT, potentially due to statin intolerance.

Abstract
Abstract
Background
Hospital-based cardiac rehabilitation and risk factor control decreases the risk of recurrent events after acute coronary syndrome (ACS). Little is known on long-term assessment and target achievement after referral to primary care. Patients with diabetes, regardless of ACS, have yearly follow-up visits in primary care, whereas there is no structured follow-up after ACS for patients without diabetes.
Purpose
To describe long-term assessment and target achievement of LDL-C and systolic blood pressure (SBP) in ACS patients after referral to primary care. Further, to compare patients with and without diabetes at the time of index ACS.
Methods
A non-interventional population-based observational study of patients with first ever ACS in a Swedish region with 390,000 inhabitants. Data on clinical measurements after ACS were collected from the electronic medical records between 2012 and 2020. Patients were followed until new ACS event, death, moving out of the county, or end of study. Target levels studied were LDL-C <1.8 mmol/L and SBP <140 mmHg. The same assessments with the addition of target levels of HbA1c ≤70 mmol/mol were evaluated in patients with diabetes.
Results
Median follow-up was 2.9 years (inter quartile range [IQR]: 1.0–5.4) and 4,733 patients were detected. Median age was 72 years (IQR 63–80) and 34% were female. Follow-up data were available for 3,579 (76%) patients any time during the first, 2,891 (61%) during the second, and 2,308 (49%) during the third year after the index ACS event. The number of patients with diabetes was 1311 (28%), and of these 921, 723, and 562 could be followed for the first, second, and third year. During the first three years, 898 (19%) of all patients with available follow-up died.
The proportion of patients with assessments of LDL-C and SBP declined for each year of follow-up and target achievement was low (Table). Among patients with diabetes a larger proportion had measurements for LDL-C and SBP, while the target achievement was similar to that of the whole study population. HbA1c was measured equally frequently as SBP and was at target in 81% of patients with diabetes during the three years of follow-up (Table).
Conclusion
The proportion of patients with follow-up assessment and measurements in primary care declined each year after the index ACS event. Patients with diabetes had more frequent LDL-C and SBP measurements but the same low target achievement after an ACS compared with patients without diabetes. This could potentially be due to an increased focus on glycaemic control at these visits. A structured long-term follow-up for ACS patients in primary care might improve both assessment and target achievement and prevent recurrent ACS events.

Abstract
Abstract
Background/Introduction
Proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors reduce low-density lipoprotein cholesterol (LDL-C) levels and the risk of cardiovascular events in patients with atherosclerotic cardiovascular disease (ASCVD) in clinical trials. In January 2019, evolocumab reimbursement recommendation in Sweden was broadened to include patients on maximally tolerated oral lipid-lowering therapy (LLT) and either ASCVD and LDL-C ≥2.5 mmol/L, or familial hypercholesterolemia (FH) with no ASCVD and LDL-C ≥3.0 mmol/L.
Purpose
Describe characteristics and LLT use in patients initiating treatment with evolocumab in the context of the 2019 reimbursement recommendation in Sweden.
Methods
Cross-sectional, population-based, retrospective, observational study of patients initiating treatment with evolocumab between January 2019 and June 2020. Data were obtained from national healthcare registers and electronic medical records, covering more than half of the Swedish population.
Results
Out of 1560 patients included, 41% had LDL-C available ≤3 months prior to treatment initiation with evolocumab. Among those with LDL-C available, 79% had ASCVD and 19% had definite, probable or possible FH with no ASCVD. Mean pre-treatment LDL-C levels were 3.7 and 5.0 mmol/L for patients with ASCVD, and FH with no ASCVD, respectively. Most of the patients, 84.6% and 80.0%, respectively, had been ever treated with both statins and ezetimibe. However, 28.0% and 38.3% of them, respectively, were not on oral LLT at the time of treatment initiation with evolocumab. Patient characteristics and LLT use are presented in Table 1.
Conclusions
Patients initiating treatment with evolocumab in Sweden had pre-treatment LDL-C levels far from treatment targets, despite being at very high risk for cardiovascular events. Most of the patients had been treated with both statins and ezetimibe in the past. However, almost a third of them were not using oral LLT at the time of treatment initiation with evolocumab. The conditions in the 2019 evolocumab reimbursement recommendation in Sweden were generally met.

Abstract
BACKGROUND Implementation of reflective practice groups in psychiatric and mental health contexts might improve the quality of care through promoting self-awareness, clinical insight, and facilitating stress management and team building. There is a need for valid and reliable instruments to test the outcomes of reflective practice groups in the mental health context. This study aimed to test the validity and reliability of the Swedish version of the Clinical Supervision Evaluation Questionnaire. METHODS The instrument was translated from English to Swedish using a translation and back-translation procedure. Data for the calculation of content validity was collected from an expert group. Data for the reliability analysis was collected from rehabilitation assistants and ward managers participating in reflective practice groups (n = 20). Content validity was measured by computing a content validity index. Construct validity was assessed by calculating the corrected item-total correlation statistics. Reliability was evaluated by analysing the Cronbach's alpha coefficient, the intraclass correlation coefficient and inter-item correlations. RESULTS The content validity index for the scale as a whole was 0.94. Item-total correlations ranged between 0.23 and 0.81, and deletion of an item did not notably improve Cronbach's alpha. Cronbach's alpha for the scale was 0.89. The intraclass correlation coefficient for single measures was 0.35. The mean inter-item correlation was .37. CONCLUSION The Swedish version of the Supervision Evaluation Questionnaire has a degree of reliability and validity that is comparable to the original version in English, indicating that it can be used as an assessment of reflective practice groups in the mental health context.

Abstract
BACKGROUND Coffee drinking has been implicated in mortality and a variety of diseases but potential mechanisms underlying these associations are unclear. Large-scale systems epidemiological approaches may offer novel insights to mechanisms underlying associations of coffee with health. OBJECTIVE We performed an analysis of known and novel protein markers linked to cardiovascular disease and their association with habitual coffee intake in the Prospective Study of the Vasculature in Uppsala Seniors (PIVUS, n = 816) and followed up top proteins in the Uppsala Longitudinal Study of Adult Men (ULSAM, n = 635) and EpiHealth (n = 2418). METHODS In PIVUS and ULSAM, coffee intake was measured by 7-day dietary records whilst a computer-based food frequency questionnaire was used in EpiHealth. Levels of up to 80 proteins were assessed in plasma by a proximity extension assay. RESULTS Four protein-coffee associations adjusted for age, sex, smoking and BMI, met statistical significance in PIVUS (FDR < 5%, P < 2.31 × 10-3 ): leptin (LEP), chitinase-3-like protein 1 (CHI3L), tumour necrosis factor (TNF) receptor 6 and TNF-related apoptosis-inducing ligand. The inverse association between coffee intake and LEP replicated in ULSAM (β, -0.042 SD per cup of coffee, P = 0.028) and EpiHealth (β, -0.025 SD per time of coffee, P = 0.004). The negative coffee-CHI3L association replicated in EpiHealth (β, -0.07, P = 1.15 × 10-7 ), but not in ULSAM (β, -0.034, P = 0.16). CONCLUSIONS The current study supports an inverse association between coffee intake and plasma LEP and CHI3L1 levels. The coffee-CHI3L1 association is novel and warrants further investigation given links between CHI3L1 and health conditions that are also potentially influenced by coffee.

Abstract
We have used Electron Tomography (ET) to reveal the detailed three-dimensional structure of particulate hydrogels, a material category common in e.g. controlled release, food science, battery and biomedical applications. A full understanding of the transport properties of these gels requires knowledge about the pore structure and in particular the interconnectivity in three dimensions, since the transport takes the path of lowest resistance. The image series for ET were recorded using High-Angle Annular Dark Field Scanning Transmission Electron Microscopy (HAADF-STEM). We have studied three different particulate silica hydrogels based on primary particles with sizes ranging from 3.6nm to 22nm and with pore-size averages from 18nm to 310nm. Here, we highlight the nanostructure of the particle network and the interpenetrating pore network in two and three dimensions. The interconnectivity and distribution of width of the porous channels were obtained from the three-dimensional tomography studies while they cannot unambiguously be obtained from the two-dimensional data. Using ET, we compared the interconnectivity and accessible pore volume fraction as a function of pore size, based on direct images on the nanoscale of three different hydrogels. From this comparison, it was clear that the finest of the gels differentiated from the other two. Despite the almost identical flow properties of the two finer gels, they showed large differences concerning the accessible pore volume fraction for probes corresponding to their (two-dimensional) mean pore size. Using 2D pore size data, the finest gel provided an accessible pore volume fraction of over 90%, but for the other two gels the equivalent was only 10-20%. However, all the gels provided an accessible pore volume fraction of 30-40% when taking the third dimension into account.

Abstract
The purpose of the study was to evaluate how older people, dependent in ADL perceive their participation in a high-intensity, functional exercise program compared to the perceptions of those participating in a control activity. Forty-eight older people living in residential care facilities answered a questionnaire about their perceptions of participating in an activity for three months. They were aged 65-98, had a mean score of 24 on Mini Mental State Examination (MMSE) and 14 on Barthel ADL Index. The participants had been randomized to exercise (n=20) or control activity (n=28). Differences in responses between exercise and control activity were evaluated using logistic and ordinal regression analyses. The results show that a majority of the exercise group perceived positive changes in lower limb strength, balance, and in the ability to move more safely and securely compared to a minority of the control group (p<0.001). Significantly more respondents in the exercise activity answered that they felt less tired due to the activity (p=0.027) and that they prioritized this activity above other activities (p=0.010). More exercise participants reported that meeting for three months was too short, and fewer that it was too long compared to the control group (p=0.038). This study shows that older people living in residential care facilities, dependent in ADL, and with mild or no cognitive impairment had positive perceptions about participating in high-intensity functional exercise. The findings support the use of a high-intensity exercise program in this population of older people.

Abstract
SUMMARY In a population of elderly women, bone cross-sectional area (CSA), cross-sectional moment of inertia (CSMI), section modulus (Z), femoral neck axis length (FNAL), and width measured with hip structure analysis (HSA) on dual-energy x-ray absorptiometry (DXA) images in the femoral neck and trochanteric regions are highly correlated to quantitative computed tomography (QCT) measurements. INTRODUCTION HSA is a method of obtaining measurements of proximal femur structure using 2D DXA technology. This study was designed to examine the correlations between HSA measurements and 3D QCT. METHODS Forty-one women (mean age, 82.8 ± 2.5 years) were measured using DXA and a 64-slice CT scanner (1 mm slice thickness, 0.29 mm in plane resolution). HSA parameters were calculated at the narrow neck (NN) and trochanteric (IT) regions on the DXA image. These regions were then translated to anatomically equivalent regions on the QCT dataset by co-registering the DXA image and QCT dataset using four DXA images acquired at different angles. RESULTS At the NN and IT regions, high linear correlations were measured between HSA and QCT for CSA r = 0.95 and 0.93, CSMI r = 0.94 and 0.93, and Z r = 0.93 and 0.89, respectively. All correlations were highly significant (p < 0.001), but there were differences in slope and offset between the two techniques, at least in part due to differences in calibration between the two techniques. FNAL and width of the bone at the NN and IT regions, physical measurements independent of the calibration, were highly correlated (r = 0.90-0.95, p < 0.001) and had slopes close to 1.0 (range, 0.978 to 1.003). CONCLUSION CSA, CSMI, Z, FNAL, and width measured by HSA correlate highly to high-resolution QCT.

Abstract
UNLABELLED Two-dimensional areal bone mineral density (aBMD) of the proximal femur measured by three-dimensional quantitative computed tomography (QCT) in 91 elderly women was compared to dual-energy X-ray absorptiometry (DXA) aBMD results measured in the same patients. The measurements were highly correlated, though QCT aBMD values were marginally lower in absolute units. Transformation of the QCT aBMD values to T score values using National Health and Nutrition Examination Survey (NHANES) DXA-derived reference data improved agreement and clinical utility. INTRODUCTION World Health Organization guidelines promulgate aBMD (g cm(-2)) measurement of the proximal femur for the diagnosis of bone fragility. In recent years, there has been increasing interest in QCT to facilitate understanding of three-dimensional bone structure and strength. OBJECTIVE To assist in comparison of QCT-derived data with DXA aBMD results, a technique for deriving aBMD from QCT measurements has been developed. METHODS To test the validity of the QCT method, 91 elderly females were scanned on both DXA and CT scanners. QCT-derived DXA equivalent aBMD (QCT(DXA) aBMD) was calculated using CTXA Hip software (Mindways Software Inc., Austin, TX, USA) and compared to DXA-derived aBMD results. RESULTS Test retest analysis indicated lower root mean square (RMS) errors for CTXA; F test between CTXA and DXA was significantly different at femoral neck (FN) and trochanter (TR) (p < 0.05). QCT underestimates DXA values by 0.02 +/- 0.05 g cm(-2) (total hip, TH), 0.01 +/- 0.04 g cm(-2) (FN), 0.03 +/- 0.07 g cm(-2) (inter-trochanter, IT), and 0.02 +/- 0.05 g cm(-2) (TR). The RMS errors (standard error of estimate) between QCT and DXA T scores for TH, FN, IT, and TR were 0.36, 0.40, 0.39, and 0.49, respectively. CONCLUSIONS This study shows that results from QCT aBMD appropriately adjusted can be evaluated against NHANES reference data to diagnose osteoporosis.

Abstract
Burgers vectors of matrix dislocations in mullite have been determined by the defocus large-angle convergent beam electron diffraction technique. Vectors of the types [100], [010], [110] and [112] were identified. These Burgers vectors are discussed in relation to the open channels and the oxygen vacancy distribution in the mullite structure. It is suggested that a short-range ordering of oxygen vacancies may account for a Burgers vector of the type [112].

Abstract
Disruption of the endothelium activates thrombogenic and fibrinolytic enzymes that cleave insulin-like growth factor binding protein-3 (IGFBP-3) in vitro. The aim of the present human study was to determine whether blood sampling, i.e., venous stasis and cannulation increase IGFBP-3 proteolysis before and/or after surgery by activating these enzymes. Serum samples obtained immediately after cannulation were compared with samples obtained from a previously inserted venous catheter. Cannulation did not increase serum IGFBP-3 proteolytic activity pre- and post-operatively, as determined by in vitro degradation of 125I-IGFBP-3. Furthermore, there was no effect on in vivo IGFBP-3 fragmentation assessed by western immunoblot. In addition, a standardized venous stasis did not affect IGFBP-3 proteolytic activity or fragmentation. Comparison of IGFBP-3 proteolytic activity before and after surgery demonstrated a significant post-operative increase. However, this could not be demonstrated immediately after the initial cannulation, due to a large individual variation at this time-point before surgery.

Abstract
A new continuum model for the growth of a single species biofilm is proposed. The geometry of the biofilm is described by the interface between the biomass and the surrounding liquid. Nutrient transport is given by the solution of a semi-linear Poisson equation. In this model we study the morphology of a chemotactic bacterial colony, which grows in the direction of increasing nutrient concentration. Numerical simulations using the level set method and finite difference schemes are presented. The results show rich heterogeneous morphology.

Abstract
Using fast-evolving microsatellites, more slowly evolving ITS markers and performing habitat analyses, we demonstrated a drastic genetic divergence and significant habitat differentiation between early- and late-flowering variants of plants morphologically belonging to Gymnadenia conopsea ssp conopsea. The two phenological variants can either be found in separate or in mixed populations. Information from microsatellite markers and ITS sequences indicated the occurrence of an early historical split between the two flowering-time variants, a split that has been maintained until the present time even within sympatric populations. Early-flowering variants were also far more genetically diverse, had more alleles per microsatellite locus and a wider habitat amplitude than late-flowering variants. As a comparison, we included G. odoratissima in the sequencing study. We found G. odoratissima to be most closely related to the early-flowering type. This indicates a more ancient divergence event between the two flowering-time variants within G. conopsea ssp conopsea than between the two different species G. odoratissima and the early-flowering variant of G. conopsea. Possible explanations to the results arrived at and possible mechanisms maintaining the genetic separation are discussed.

Abstract
Gymnadenia conopsea (L.) R. Br., or the fragrant orchid, is one of many plant species negatively influenced by new practices in agriculture and forestry during the last decades. This study describes the level of microsatellite variation within and among 10 Swedish populations of this species. It was not possible to detect strong effects of small population size or fragmentation. In general, the species had high genetic variation within and low genetic divergence among populations, although the correlation between population size and number of alleles was close to significance at the 95% level. Also, a significant isolation by distance effect was observed, indicating the presence of modest restrictions in gene dispersal between the investigated populations.

Abstract
In Atlantic salmon, Salmo salar, the mineral rate of vertebrae in a given fish varies according to the position of the vertebra along the rachidian axis. Indeed, the mean rate goes from 49% in the anterior vertebrae and raises to 51% in post-truncal vertebrae. Although no significant difference in the mineral rate was noticed between males and females either in the lower river basin or after spawning, the mineral rate of vertebral bone decreased significantly (1-2%) during spawning migration. Vertebrae, like scales, are an important reservoir of calcium from which fasting salmon draws the minerals and organic materials necessary for the substantial remodeling of cranial bones in males and for sexual maturation. We hypothesize that mineral decrease in vertebrae may be the result of a halastasic demineralization of the vertebral tissues.

Abstract
The gastric bacterial flora and its influence on the 13C-urea breath test (UBT) for detection of Helicobacter pylori infection was studied in a pig model. Seven SPF minipigs were used. H. pylori or a mix of other urease positive bacteria were administered orally. UBT, serum and biopsies for histology and culture were collected. Our results show that UBT is not specific for H. pylori in pigs as the gastric bacterial flora is responsible for the high UBT values observed. Furthermore, the Ellegaard Göttingen SPF minipigs are not useful in an animal model for H. pylori studies.

Abstract
Previously healthy sows, seropositive to Mycoplasma hyopneumoniae, developed clinical signs of mycoplasmosis, as well as increasing amounts of antibodies to M. hyopneumoniae during an outbreak of the disease in a herd. During the early phase of the outbreak, young piglets (2 weeks) with maternal antibodies remained healthy while older seronegative piglets (4-7 weeks) developed the disease. The duration of the maternal antibodies to M. hyopneumoniae varied between litters and was related to the amount of antibodies in the serum of the dam. In sows, the level of serum antibodies decreased continuously from 4 weeks ante partum to partus, and the level of antibodies in the whey of colostrum was comparable to that in serum 4 weeks ante partum. After loss of maternal antibodies to M. hyopneumoniae, seropositive animals were not found among piglets younger than 9 weeks. Therefore peripheral blood mononuclear cells (PBMC) were collected from various age categories of piglets in order to measure the ability to produce antibodies to M. hyopneumoniae in vitro. PBMC obtained from piglets aged 1 and 3 weeks produced few antibodies to M. hyopneumoniae. Significantly higher levels of antibodies to M. hyopneumoniae were produced by PBMC obtained from pigs aged 5-9 weeks. Thus, the ability of PBMC to produce antibodies to M. hyopneumoniae in vitro seemed to be age-dependent.

Abstract
OBJECTIVE To investigate the possible relationship between serum levels of prostate specific antigen (PSA), dihydrotestosterone (DHT), testosterone, sexual-hormone binding globulin (SHBG) and tumour stage, grade and ploidy in 65 cases of prostate cancer diagnosed in a screening study compared to 130 controls from the same population. PATIENTS, SUBJECTS AND METHODS From a population of 26,602 men between the ages of 55 and 70 years, 2400 were selected randomly and invited to undergo screening for prostate cancer using a digital rectal examination, transrectal ultrasonography and PSA analysis. Among the 1782 attendees, 65 cases of prostate cancer were diagnosed. Each case was matched with two control subjects of similar age and prostate volume from the screening population. Frozen serum samples were analysed for PSA, DHT, testosterone and SHBG, and compared to the diagnosis and tumour stage, grade and ploidy. Comparisons between these variables, and multivariate and regression analyses were performed. RESULTS There were significant differences in PSA level with all variables except tumour ploidy. DHT levels were slightly lower in patients with prostate cancer but the difference was not statistically significant. There was a trend towards lower DHT values in more advanced tumours and the difference for T-stages was close to statistical significance (P = 0.059). Testosterone levels were lower in patients with cancer than in the control group, but the differences were not significant. There was no correlation between testosterone levels, tumour stage and ploidy, but the differences in testosterone level in tumours of a low grade of differentiation compared to those with intermediate and high grade was nearly significant (P = 0.058). The testosterone/DHT ratio tended to be higher in patients with more advanced tumours. SHBG levels were lower in patients with cancer than in controls but the differences were not statistically significant. There were no systematic variations of tumour stage, grade and ploidy. Multivariate analysis showed that if the PSA level was known, then DHT, testosterone or SHBG added no further information concerning diagnosis, stage, grade or ploidy. Regression analysis on T-stage, PSA level and DHT showed an inverse linear relationship between PSA and DHT for stage T-3 (P = 0.035), but there was no relationship between PSA and testosterone. CONCLUSION PSA was of value in discriminating between cases and controls and between various tumour stages and grades, but no statistically significant correlation was found for ploidy. If PSA level was known, no other variable added information in individual cases. Within a group, DHT levels tended to be lower among cases and in those with more advanced tumours. There was an inverse relationship between tumour volume, as defined by PSA level, and 5 alpha-reductase activity, as defined by DHT level, and the testosterone/DHT ratio. This trend was most obvious with T-stage. No systematic variation were found in the levels of testosterone or SHBG.

Abstract
"The focus of this paper is an empirical analysis of the effects of taxation on women's incentives to contribute to family income. Data on earnings and individual characteristics in 1984 for married or cohabiting Swedish couples...are used together with similar data on German couples.... The main features of the personal income taxation of the two countries have been programmed, and are used for simulating after tax incomes using both tax systems for both countries.... The difference between the Swedish and German tax systems is an important factor in explaining why Swedish women participate more than German women in the labor market, although paid parental leaves and subsidized childcare are other important explanations for the Swedish situation."

Abstract
General well-being, adverse effects and anti-hypertensive efficacy have been investigated in a double blind, parallel-group, dose-response multicentre study of diltiazem and metoprolol monotherapy for hypertension. 128 patients with primary hypertension were included from 10 participating centres. The patients were randomized to receive oral diltiazem 120-240-360 mg/day or metoprolol 50-100-200 mg/day. Each dose was given for a 4-week period as a forced titration regime. In all 119 patients, 59 and 60, respectively, on diltiazem and metoprolol completed the study protocol. There were dose-dependent reductions in supine and standing blood pressures (BP) after both diltiazem and metoprolol therapy. In the diltiazem group, supine BP was reduced by 10 (11)/10 (6) mmHg (SBP/DBP) at the highest dose level, and the corresponding values for the metoprolol group were 7 (16)/8 (9) mmHg (SBP/DBP). Target pressures (DBP less than or equal to 90 mmHg and/or a reduction in DBP of greater than or equal to 10%) were reached in 63% and 48% of the patients, respectively. The incidence and severity of dose-dependent adverse effects, as evaluated by spontaneous reports or open and direct questioning, did not differ between treatments. Subjective well-being, evaluated by a self-administered questionnaire, the MSE-profile, did not differ significantly between diltiazem and metoprolol therapy. However, after an initial slight deterioration, contentment and vitality tended to improve with increasing doses of diltiazem, while a dose-related deterioration in these variables was observed on metoprolol therapy. At the highest dose levels, contentment and vitality tended to be better in the diltiazem than the metoprolol group. Thus, diltiazem and metoprolol in daily doses of 120-360 mg and 50-200 mg, respectively, produce comparable and parallel reductions in supine and standing BP. However, while subjective well-being tended to improve with increasing doses of diltiazem, there was a negative trend for metoprolol. It is concluded that diltiazem, given as monotherapy to hypertensive patients, does not impair subjective well-being.

Abstract
In a randomized, double-blind, parallel group study, diltiazem was compared with metoprolol as add-on therapy to diuretic treatment in 115 patients with hypertension. Following a placebo and diuretic period of four weeks, patients were randomized to either slow release diltiazem 90 mg twice daily or metoprolol 100 mg once daily using a double dummy technique. If after four weeks a target supine diastolic blood pressure (DBP) less than or equal to 90 mmHg pressure was not reached, the doses of diltiazem and metoprolol were doubled. Supine inclusion systolic/diastolic blood pressures (SBP/DBP) at randomization were 158 +/- 13 (mean +/- SD)/102 +/- 5 mmHg in the diltiazem group and 158 +/- 17/101 +/- 6 mmHg in the metoprolol group. Active therapy significantly lowered SBP and DBP in both groups by 7-10%. Heart rate was significantly lowered in both groups, although the effect of metoprolol was more pronounced. Response rates (supine DBP less than or equal to 90 mmHg and/or decreased by greater than or equal to 10%) were 43% on diltiazem 90 mg twice daily and 52% on metoprolol 100 mg once daily, increasing to 82% and 62%, respectively, after dose escalations. No serious side effects were seen, but three patients, two on diltiazem and one on metoprolol, were withdrawn from the study due to severe headache, nausea and bradycardia respectively. of mild to moderate adverse reactions, tiredness was most frequent, occurring in 14.5% and 15.8% on active diltiazem and metoprolol therapy, respectively. We conclude that both diltiazem and metoprolol lower BP when added to diuretics in hypertensive patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A double-blind, parallel-group multicentre study has been done to compare the antihypertensive properties, effects on serum lipoproteins and adverse effect profiles of diltiazem and metoprolol given as monotherapy to primary hypertensive patients. 128 patients were included from 10 participating centers. Following a placebo wash-out period of 5 weeks, patients were randomized either to diltiazem or metoprolol treatment according to a forced titration regimen. Each dose was given for a 4-week period in a stepwise regimen. A total of 119 patients, 59 and 60 in the two groups, completed the study. Supine and standing BPs were reduced in a similar, dose-dependent fashion by diltiazem and metoprolol. In the former supine BP fell from 161/101 to 151/91 mmHg at the highest dose level. In the latter patients, supine BP at the highest dose level was reduced from 161/102 to 155/94 mmHg. Target pressures (DBP less than or equal to 90 mmHg and/or DBP reduction of greater than or equal to 10%) were reached in 63% and 48% of the patients, respectively. HDL-cholesterol was increased in diltiazem-treated patients and decreased in those on metoprolol. Otherwise, serum lipoproteins did not differ significantly between treatments. The incidence and severity of dose-dependent adverse effects did not differ significantly between treatments, although moderate to distressing side effects were reported more commonly by metoprolol-treated patients. Ankle oedema and breathlessness tended to be more common on diltiazem therapy, while tiredness, increased sweating and sleep disturbances appeared to be experienced more frequently by metoprolol-treated patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The angiotensin I-converting enzyme (peptidyl-dipeptide hydrolase, EC 3.4.15.1) inhibitor, ramiprilat (2-[N-[(S)-1-ethoxycarbonyl-3-phenylpropyl]-L-Ala]-(1S,3S,5S)-2- azabicyclo[3.3.0]octane-3-carboxylic acid), is shown to exist in tow conformational isomers, cis and trans, which interconvert around the amide bond. The two conformers were separated by reversed-phase high-performance liquid chromatography. The conformers were identified by nuclear Overhauser effect measurements. From line shape analysis the isomerization rate constants were determined to be kcis----trans = 15 s-1 and ktrans----cis = 5 s-1 at 368 K in [2H]phosphate buffer (p2H 7.5). By enzyme kinetic studies using 3-(2-furylacryloyl)-L-Phe-Gly-Gly as substrate, the trans conformer was found to be the most potent enzyme inhibitor, whereas the cis conformer had a very low inhibitory effect. A new inhibition mechanism is presented for this type of slow, tight-binding inhibitors that contain an amide bond. This mechanism involves an equilibrium between the two conformers and the enzyme-bound inhibitor complex.

Abstract
Liquid chromatography with amperometric detection was employed for the determination of the dihydroxycatecholamine metabolites, 3,4-dihydroxyphenylethylene glycol (DOPEG) and 3,4-dihydroxyphenylacetic acid (DOPAC) in plasma. The compounds were isolated from plasma by adsorption onto alumina, the elution from which was found to be strongly dependent on the acid used. Conditions for the separation on octadecyl-bonded silica were evaluated with particular reference to the influence of pH, ion-pairing anions and quaternary ammonium ions. Recoveries of ca 85% and relative standard deviations of about 3% were obtained for the assay of endogenous concentrations.

Abstract
A capsule preparation containing small, enteric-coated granules of digoxin was developed to prevent acid hydrolysis of the drug in the stomach and to diminish the variation in plasma glycoside concentration during the intervals between doses. The absorption and metabolism of tritiated digoxin after a single oral loading dose of this formulation (Formulation C) were compared to those after ingestion of a digoxin solution (Formulation S) by 8 healthy men. Drug concentrations were measured by radioimmunoassay (RIA) and liquid chromatography (LC). The percentage of the digoxin dose excreted in the urine during 72 h, as measured by RIA, was significantly lower after the capsule (20.5 +/- 2.0% vs 36.2 +/- 3.0% after S, mean +/- SEM) but total urinary radioactivity after the two treatments was similar (C 35.3 +/- 5.2 and S 41.2 +/- 2.6%; p greater than 0.05). The discrepancy was mainly due to significantly greater excretion of dihydrodigoxin after the capsule (m 12.8%, range 0-28.6% of the dose) than after the digoxin solution (m 5.4%, range 0-14.5%). Dihydrodigoxin was not measured by the RIA. The recovery of hydrolysis metabolites (LC) was greater during the first 24 h after S (2.3 +/- 0.6% vs 0.9 +/- 0.3% after C; p less than 0.05). The peak plasma concentration of digoxin (RIA) was significantly reduced and delayed after intake of C (2.5 +/- 0.4 nmol/l at 3.8 +/- 0.3 h vs. 8.3 +/- 0.8 nmol/l at 0.9 +/- 0.1 h after S), and so was the shortening of electromechanical systole at 1.5 h, 2.5 h, and 3 h.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A liquid chromatographic method for the determination of free urinary concentrations of epinephrine, norepinephrine and dopamine is presented. For urine samples, pre-purified by adsorption onto alumina, ion-exchange chromatography was, in terms of selectivity, found to be superior to the more widely used reversed-phase chromatography. The column eluates were monitored with an electrochemical detector utilizing a glassy carbon working electrode. The method allows determination of the concentrations in 0.5 ml of normal urine samples with a relative standard deviation below 2%.
