Care co‐ordination for older people in the third sector: scoping the evidence

The third sector has played a significant role internationally in the delivery of adult social care services for many years. Its contribution to care co‐ordination activities for older people, however, in England and elsewhere, is relatively unknown. A scoping review was therefore conducted to ascertain the character of the literature, the nature and extent of third sector care co‐ordination activity, and to identify evidence gaps. It was undertaken between autumn 2013 and summer 2014 and updated with additional searches in 2016. Electronic and manual searches of international literature using distinct terms for different approaches to care co‐ordination were undertaken. From a total of 835 papers, 26 met inclusion criteria. Data were organised in relation to care co‐ordination approaches, types of third sector organisation and care recipients. Papers were predominantly from the UK and published this century. Key findings included that: a minority of literature focused specifically on older people and that those doing so described only one care co‐ordination approach; third sector services tended to be associated with independence and person‐centred practice; and working with the statutory sector, a prerequisite of care co‐ordination, was challenging and required a range of features to be in place to support effective partnerships. Strengths and weaknesses of care co‐ordination practice in the third sector according to key stakeholder groups were also highlighted. Areas for future research included the need for: a specific focus on older people's experiences; an investigation of workforce issues; detailed examination of third sector practices, outcomes and costs; interactions with the statutory sector; and an examination of quality assurance systems and their appropriateness to third sector practice. The main implication of the findings is a need to nurture variety within the third sector in order to provide older people and other adults with the range of service options desired.     

Hormonal patterns in men with prediabetes and diabetes in NHANES III: possible links with prostate cancer

Intra-vascular blood velocity and volumetric flow rate calculated from dynamic 4D CT angiography using a time of flight technique

We examine a time of flight (TOF) approach for the analysis of contrast enhanced 4D volumetric CT angiography scans to derive and display blood velocity in arteries. Software was written to divide blood vessels into a series of cross sections and to track contrast bolus TOF along the central vessel axis, which was defined by a user, from 4D CT source data. Time density curves at each vessel cross section were fit with quadratic, Gaussian, and gamma variate functions to determine bolus time to peak (TTP). A straight line was used to plot TTP versus vessel path length for all three functions and the slope used to calculate intraluminal velocity. Software was validated in a simulated square channel and non-pulsatile flow phantom prior to the calculation of blood velocity in the major cerebral arteries of 8 normal patients. The TOF algorithm correctly calculates intra-luminal fluid velocity in eight flow conditions of the CT flow phantom where quadratic functions were used. Across all conditions, in phantoms and in vivo, the success of calculations depended strongly on having a sufficiently long path length to make measurements and avoiding venous contamination. Total blood flow into the brain was approximately 17 % of a normal 5 L cardiac output. The technique was explored in vivo in a patient with subclavian steal syndrome, in the pulmonary arteries and in the iliac artery from clinical 4D CT source data.  Intravascular blood velocity and flow may be calculated from 4D CT angiography using a TOF approach.     

Reviewing and addressing the link between mass media and the increase in obesity among European children: The European Academy of Paediatrics (EAP) and The European Childhood Obesity Group (ECOG) consensus statement

This study reviewed the link between social media and the growing epidemic of childhood obesity in Europe. A task force from the European Academy of Paediatrics and the European Childhood Obesity Group searched published literature and developed a consensus statement. It found that there was evidence of a strong link between obesity levels across European countries and childhood media exposure and that parents and society needed a better understanding of the influence of social media on dietary habits. Conclusion. Health policies in Europe must take account of the range of social media influences that promote the development of childhood obesity.     

Appendicitis as a cause of intestinal strangulation: a case report and review

Intestinal obstruction is a common surgical emergency caused by varied conditions. Appendicitis as a cause is both uncommon and unsuspected. Strangulation of intestine caused by appendicitis is extremely rare with very few cases reported in literature. The diagnosis of such a condition is possible only on table, with CT having questionable value. This is a very rare and dangerous complication of a very common disease which can easily be overlooked. Every emergency surgeon needs to be aware of such a possibility.
