Planning for the perfect storm: perceptions of UK mental health professionals on the increasing impacts of climate change on their service users

Introduction Climate change poses a considerable risk of further increasing the world's mental health burden. The ways that, and extent to which, climate change is affecting mental health service users is poorly known. Mental health professionals (MHP)s' views on the nature of climate-related distress and the need for specialist training to support service users is undetermined globally. Methods A questionnaire survey was disseminated to an opportunity sample of MHPs based in the United Kingdom (UK). It investigated whether MHPs perceived that the number of service users mentioning climate change as affecting their mental health or emotional distress had increased in the five years prior to 2021, and if they believe it will increase further. The survey explored MHPs’ perceptions of the influence of climate change on service users’ mental health needs, if they perceive this to be rational, and if they feel adequately prepared to manage climate change related mental health problems or emotional distress. Results We surveyed 75 MHPs, including professionals in psychotherapy (38), psychology (19), psychiatry (6). MHPs reported a significant increase in the perceived prevalence of mental health problems or emotional distress related to climate change, believing this increase will continue. MHPs reported a range of impacts on service users due to climate change, typically viewed as a rational response. MHPs felt equipped to manage the consequences of climate change but would benefit from specific training. Conclusions Our results indicate an increasing incidence of climate-related emotional distress among service users as perceived by MHPs. The expectation among professionals is that this service need is here now but will continue to increase in the future, with potential implications for the provision of training

Numerical Modelling of Ice Interaction with Rubble Mound Berms in the Caspian Sea

Numerical modelling of sea ice is a useful tool in predicting ice rubble formation around offshore and coastal structures. Such models can capably predict rubble height and extent, allowing engineers to pinpoint \u201cproblem\u201d scenarios for structures where ice interaction, and its potential for extensive damage, is a concern. This paper describes numerical simulations that were conducted to examine floating ice interaction with a structure located in the Caspian Sea and its planned surrounding protective rubble mounds. Spatial and temporal distributions of ice rubble pile-up height and depth, as well as forces on the mounds, were determined. The numerical model examined a number of different rock mound configurations, the influence of the direction of ice movement and ice sheet thickness. The results are compared with reported pile-up heights, collected from the field site.NRC publication: Ye

South African Hypertension Guideline 2006

Outcomes. Extensive data from many randomised controlled trials have shown the benefit of treating hypertension. The target blood pressure (BP) for antihypertensive management should be systolic BP < 140 mmHg, diastolic BP < 90 mmHg, with minimal or no drug side-effects. However, a lesser reduction will elicit benefit although this is not optimal. The reduction of BP in the elderly should generally be achieved gradually over 6 months. Stricter BP control is required for patients with end-organ damage, co-existing risk factors and co-morbidity, e.g. diabetes mellitus. Co-existent risk factors should also be controlled. Benefits. Reduction in risk of stroke, cardiac failure, renal insufficiency and coronary artery disease. The major precautions and contraindications to each antihypertensive drug recommended are listed. Recommendations. Correct BP measurement procedure is described. Evaluation of cardiovascular risk factors and recommendations for antihypertensive therapy are stipulated. The total cardiovascular disease risk profile should be determined for all patients and this should inform management strategies. Lifestyle modification and patient education are cornerstones in the management of every patient. Drug therapy for the patient with uncomplicated hypertension should be as follows: first line – low-dose thiazide or thiazide-like diuretics; second line – add either an angiotensin-converting enzyme inhibitor (ACE-I) or a calcium channel blocker (CCB); third line – add another second-line drug not already used. In resistant hypertension where a fourth drug is needed, use either a centrally acting drug, vasodilator, alpha-blocker, or beta-blocker. The order of drug choice may change in those with compelling indications for a particular drug class. The guideline includes management of specific situations including hypertensive emergency and urgency, severe hypertension with target-organ damage and hypertension in diabetes mellitus, etc. Validity. The guideline was developed by a joint Southern African Hypertension Society and National Department of Health Directorate: Chronic Diseases, Disabilities and Geriatrics working group. Input was also obtained from representatives of the various related professional societies

On the investigations of galaxy redshift periodicity

In this article we present a historical review of study of the redshift periodicity of galaxies, starting from the first works performed in the seventies of the twentieth century until the present day. We discuss the observational data and methods used, showing in which cases the discretization of redshifts was observed. We conclude that galaxy redshift periodisation is an effect which can really exist. We also discussed the redshift discretization in two different structures: the Local Group of galaxies and the Hercules Supercluster. Contrary to the previous studies we consider all galaxies which can be regarded as a structure member disregarding the accuracy of velocity measurements. We applied the power spectrum analysis using the Hann function for weighting, together with the jackknife error estimator. In both the structures we found weak effects of redshift periodisation.Comment: 10 pages, 4 figures, to be published in Part. and Nucl. Lett. 200
