Living in the intertidal: desiccation and shading reduce seagrass growth, but high salinity or population of origin have no additional effect.

The limiting effects of stressors like desiccation, light and salinity on seagrass growth and distribution are well-studied. However, little is known about their interactive effects, and whether such effects might differ among populations that are adapted to different local conditions. In two laboratory experiments we tested (a) if growth and development of intertidal, temperate is affected by emergence time (experiment 1 and 2), and (b) how this is affected by an additional, second stressor, namely shading (experiment 1) or high salinity (25, 30 and 35, experiment 2).

A 12-month follow-up study of treating overweight schizophrenic patients with aripiprazole.

Objective: To investigate the feasibility of switching overweight schizophrenic patients to aripiprazole and to assess the impact of 12 months of aripiprazole treatment on weight in routine practice.

Method: This was a non-controlled cohort study in overweight schizophrenic patients. Data were collected before treatment with aripiprazole was started and at 12-month follow-up.

A patient treated with olanzapine developing diabetes de novo: proposal for hyperglycaemia screening.

We report a patient with schizophrenia who developed diabetes mellitus during treatment with olanzapine. The case confirms the pattern of atypical antipsychotic-related diabetic emergencies: rapid onset in relatively young patients, often with severe glucose derangements and serious complications. As diabetic emergencies have a high morbidity and mortality, regular glucose screening should be performed in patients with schizophrenia treated with atypical antipsychotics.
