Governance and management dynamics of landscape restoration at multiple scales: Learning from successful environmental managers in Sweden.

Due to a long history of intensive land and water use, habitat networks for biodiversity conservation are generally degraded in Sweden. Landscape restoration (LR) is an important strategy for achieving representative and functional green infrastructures. However, outcomes of LR efforts are poorly studied, particularly the dynamics of LR governance and management. We apply systems thinking methods to a series of LR case studies to analyse the causal structures underlying LR governance and management in Sweden. We show that these structures appear to comprise of an interlinked system of at least three sets of drivers and four core processes. This system exhibits many characteristics of a transformative change towards an integrated, adaptive approach to governance and management. Key challenges for Swedish LR projects relate to institutional and regulatory flexibility, the timely availability of sufficient funds, and the management of learning and knowledge production processes. In response, successful project leaders develop several key strategies to manage complexity and risk, and enhance perceptions of the attractiveness of LR projects.

Elevated cholesterol levels associated with nonresponse to fluoxetine treatment in major depressive disorder.

Previous studies have suggested that patients with major depressive disorder may have lower cholesterol levels compared to healthy controls. The purpose of this study was to examine the relationship between pretreatment serum cholesterol levels and clinical response to treatment with fluoxetine among outpatients with major depression. Three hundred and twenty-two depressed outpatients meeting DSM-III-R criteria for major depressive disorder were enrolled in an 8-week, fixed-dose, open trial of fluoxetine 20 mg/day. Nonfasting serum cholesterol levels were obtained for all patients before starting fluoxetine. All patients were drug free for a minimum of 2 weeks prior to the onset of the study. Clinical response was defined as a 50% or greater decrease in the 17-item Hamilton Rating Scale for Depression (HAM-D-17) score at endpoint compared to baseline. Cholesterol levels were classified as either elevated (defined as a level equal to or greater than 200 mg/dL) or nonelevated (defined as a level less than 200 mg/dL). Among the 322 outpatients, 51.6% were classified as having elevated and 48.4% as having nonelevated cholesterol levels at baseline (mean cholesterol level 238.6 +/- 33.4 mg/dL vs. 170.4 +/- 22.2 mg/dL, respectively). Depressed patients with elevated cholesterol levels did not significantly differ in gender ratio but were significantly older than depressed patients with nonelevated cholesterol levels (P <.0001). After adjusting for age, gender, and Body Mass Index (BMI), depressed patients with elevated cholesterol levels were significantly more likely to be nonresponders to fluoxetine treatment than were depressed patients with nonelevated cholesterol levels (P < 0.05). Elevated serum cholesterol levels appear to be associated with poorer response to fluoxetine treatment. Further studies are needed to confirm our findings.

The pharmacologic management of SSRI-induced side effects: a survey of psychiatrists.

Despite the superior side effect profile of the newer antidepressants over the tricyclics and monoamine oxidase inhibitors, all newer antidepressants are associated with a wide array of side effects. Clinicians are constantly confronted with the challenge of managing these side effects in the context of minimal research to prove one management strategy is more effective than another. The purpose of this study was to examine prescribing practices regarding the management of SSRI-associated side effects in a sample of psychiatrists attending a psychopharmacology review course. A total of 439 out of 800 clinicians (55%) attending a psychopharmacology review course responded to our questionnaire that was given prior to beginning the review course, though not all respondents answered all four items on the questionnaire. Among these items were questions designed to assess clinician preference for the management of SSRI-induced side effects. As a treatment for SSRI-induced sexual dysfunction, 43% (143/330) chose adding bupropion, while 36% (120/330) opted to switch agents as their first choice; for SSRI-induced insomnia, 78% (264/326) chose adding trazodone. Switching agents was the first choice of 61% (214/353) of clinicians for managing SSRI-induced agitation, 93% (339/363) for managing SSRI-associated weight gain. In an effort to manage most SSRI-associated side effects (with the exception of sexual dysfunction and insomnia), the majority of the clinicians responding to our survey opted to switch agents rather than add a specific medication to the existing SSRI. In our opinion, this practice may reflect the relative lack of research studies on the role of adjunctive treatments in the management of SSRI-induced side effects and/or the tendency to favor monotherapy over polypharmacy.
