Guidelines for management of hypertension: report of the third working party of the British Hypertension Society.

Abstract: Use non-pharmacological measures in all hypertensive and borderline hypertensive people. Initiate antihypertensive drug therapy in people with sustained systolic blood pressures (BP) >/=160 mm Hg or sustained diastolic BP >/=100 mm Hg. Decide on treatment in people with sustained systolic BP between 140 and 159 mm Hg or sustained diastolic BP between 90 and 99 mm Hg according to the presence or absence of target organ damage, cardiovascular disease or a 10-year coronary heart disease (CHD) risk of >/=15% according to the Joint British Societies CHD risk assessment programme/risk chart. In people with diabetes mellitus, initiate antihypertensive drug therapy if systolic BP is sustained >/=140 mm Hg or diastolic BP is sustained >/=90 mm Hg. In non-diabetic hypertensive people, optimal BP treatment targets are: systolic BP /=15% and in whom blood pressure is controlled to the audit standard. In accordance with existing British recommendations, statin therapy is recommended for hypertensive people with a total cholesterol >/=5 mmol/L and established vascular disease, or 10-year CHD risk >/=30% estimated from the Joint British Societies CHD risk chart. Glycaemic control should also be optimised in diabetic subjects. Specific advice is given on the management of hypertension in specific patient groups, ie, the elderly, ethnic subgroups, diabetes mellitus, chronic renal disease and in women (pregnancy, oral contraceptive use and hormone replacement therapy). Suggestions for the implementation and audit of these guidelines in primary care are provided.

Basic principles of real-time quantitative PCR

Abstract: Real-time quantitative PCR allows the sensitive, specific and reproducible quantitation of nucleic acids. Since its introduction, real-time quantitative PCR has revolutionized the field of molecular diagnostics and the technique is being used in a rapidly expanding number of applications. This exciting technology has enabled the shift of molecular diagnostics toward a high-throughput, automated technology with lower turnaround times. This article reviews the basic principles of real-time PCR and describes the various chemistries available: the double-stranded DNA-intercalating agent SYBR Green 1, hydrolysis probes, dual hybridization probes, molecular beacons and scorpion probes. Quantitation methods are discussed in addition to the competing instruments available on the market. Examples of applications of this important and versatile technique are provided throughout the review.

Depression and anxiety in long-term cancer survivors compared with spouses and healthy controls: a systematic review and meta-analysis

Abstract: Summary Background Cancer survival has improved in the past 20 years, affecting the long-term risk of mood disorders. We assessed whether depression and anxiety are more common in long-term survivors of cancer compared with their spouses and with healthy controls. Methods We systematically searched Medline, PsycINFO, Embase, Science Direct, Ingenta Select, Ovid, and Wiley Interscience for reports about the prevalence of mood disorders in patients diagnosed with cancer at least 2 years previously. We also searched the records of the International Psycho-oncology Society and for reports that cited relevant references. Three investigators independently extracted primary data. We did a random-effects meta-analysis of the prevalences of depression and anxiety in cancer patients compared with spouses and healthy controls. Findings Our search returned 144 results, 43 were included in the main analysis: for comparisons with healthy controls, 16 assessed depression and ten assessed anxiety; of the comparisons with spouses, 12 assessed depression and five assessed anxiety. The prevalence of depression was 11·6% (95% CI 7·7–16·2) in the pooled sample of 51 381 cancer survivors and 10·2% (8·0–12·6) in 217 630 healthy controls (pooled relative risk [RR] 1·11, 95% CI 0·96–1·27; p=0·17). The prevalence of anxiety was 17·9% (95% CI 12·8–23·6) in 48 964 cancer survivors and 13·9% (9·8–18·5) in 226 467 healthy controls (RR 1·27, 95% CI 1·08–1·50; p=0·0039). Neither the prevalence of depression (26·7% vs 26·3%; RR 1·01, 95% CI 0·86–1·20; p=0·88) nor the prevalence of anxiety (28·0% vs 40·1%; RR 0·71, 95% CI 0·44–1·14; p=0·16) differed significantly between cancer patients and their spouses. Interpretation Our findings suggest that anxiety, rather than depression, is most likely to be a problem in long-term cancer survivors and spouses compared with healthy controls. Efforts should be made to improve recognition and treatment of anxiety in long-term cancer survivors and their spouses. Funding None.

Non-invasive assessment of axonal fiber connectivity in the human brain via diffusion tensor MRI.

Abstract: A technique for assessing in vivo fiber connectivity in the human brain is presented. The method utilizes a novel connectivity algorithm that operates in three spatial dimensions and uses estimates of fiber tract orientation and tissue anisotropy, obtained from diffusion tensor magnetic resonance imaging, to establish the pathways of fiber tracts. Sample in vivo connectivity images from healthy human brain are presented that demonstrate connections in the white matter tracts. White matter connectivity information is potentially of interest in the study of a range of neurological, psychiatric, and developmental disorders and shows promise for following the natural history of disease.
