- Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restoration, and valuation of these ecosystems. We collated a global dataset of tidal marsh soil organic carbon (MarSOC) from 99 studies that includes location, soil depth, site name, dry bulk density, SOC, and/or soil organic matter (SOM). The MarSOC dataset includes 17,454 data points from 2,329 unique locations, and 29 countries. We generated a general transfer function for the conversion of SOM to SOC. Using this data we estimated a median (± median absolute deviation) value of 79.2 ± 38.1 Mg SOC ha−1 in the top 30 cm and 231 ± 134 Mg SOC ha−1 in the top 1 m of tidal marsh soils globally. This data can serve as a basis for future work, and may contribute to incorporation of tidal marsh ecosystems into climate change mitigation and adaptation strategies and policies.

Improved treatment and control of hypertension in Swedish primary care: results from the Swedish primary care cardiovascular database
- 2017

Ingår i: Journal of Hypertension. - : Ovid Technologies (Wolters Kluwer Health). - 0263-6352. ; 35:10, s. 2102-2108

Tidskriftsartikel (refereegranskat)abstract
- Objective:To study temporal trends in hypertension treatment and control in Swedish primary care, in relation to clinical characteristics, comorbidity, and drug treatment.Materials and methods:Repeated cross-sectional analysis of 43239 hypertensive patients attending primary care in 2001-2002 and of 62407 patients in 2007-2008.Results:Mean blood pressure (BP) 2007-2008 was 143/79mmHg in women and 142/81mmHg in men. Cardiovascular comorbidity and diabetes were present in 13 and 15% of women, and in 18 and 20% of men. Overall BP reductions from 2001-2002 to 2007-2008 were 9.0/3.1mmHg; greater in women than men, with advancing age, and in patients with comorbidity (all P<0.001). Attainment of target BP (<140/90mmHg) increased from 24 and 26% in women and men (2001-2002) to 37 and 37% (2007-2008; all P<0.001). Most common drug classes in 2001-2002 were, in descending frequency, blockers, diuretics, and calcium channel blockers (both sexes), and in 2007-2008 blockers, diuretics, and angiotensin-converting enzyme inhibitors in women, and blockers, angiotensin-converting enzyme inhibitors, and diuretics in men. The number of drug classes/patient increased from 1.5 (2001-2002) to 1.8 (2007-2008; P<0.001) but remained low (1.7) in those above target BP.Conclusion:BP control in hypertensive patients attending Swedish primary care has improved over 5-7 years, and more so in high-risk groups. There is, however, room for improvement. In uncontrolled hypertension the combination of several drug classes remain low.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The AMS C-14 technique has the advantage that small samples of Late Quaternary age can be dated with high accuracy, and that errors due to reservoir effects can be avoided if specifically determined terrestrial micro- and macrofossils are measured. Howeve

The Swedish Primary Care Cardiovascular Database (SPCCD): 74 751 hypertensive primary care patients
- 2014

- Objective. To describe the Swedish Primary Care Cardiovascular Database, SPCCD. Design. Longitudinal data from electronic medical records, linked to national registers. Setting. 48 primary healthcare centres in urban (south-western Stockholm) and rural (Skaraborg) regions in Sweden. Subjects. Patients diagnosed with hypertension 2001-2008. Main outcome measures. Blood pressure (BP) and impact of retrieval of data on BP levels, clinical characteristics, co-morbidity and pharmacological treatment. Results. The SPCCD contains 74 751 individuals, 56% women. Completeness of data ranged from >99% for drug prescriptions to 34% for smoking habits. BP was recorded in 98% of patients during 2001-2008 and in 63% in 2008. Mean BP based on the last recorded value in 2008 was 142 +/- 17/80 +/- 13 mmHg. Digit preference in BP measurements differed between the two regions, p < 0.001. Antihypertensive drugs were prescribed in primary healthcare to 88% of the patients in 2008; however, when all prescribers were included 96% purchased their drugs. Cardiovascular co-morbidity and diabetes mellitus were present in 28% and 22%, respectively. Conclusion. This large and representative database shows that there is room for improvement of BP control in Sweden. The SPCCD will provide a rich source for further research of hypertension and its complications.
