Is children's weight a public health or a private family issue? A qualitative analysis of online discussion about National Child Measurement Programme feedback in England.

BACKGROUND: The National Child Measurement Programme (NCMP) is a child weight monitoring system in England, taking place in the first and final years of primary school. Many local authorities consider it important to inform parents if their child is overweight, and do so by letter alongside the offer of support and advice. Such letters have been met with mixed reactions from parents, but research seeking to better understand parents' responses is often limited by reliance on survey data and low participation rates. This study aimed to collect a broad variety of perspectives on the programme by analyzing views expressed in parent-to-parent discussions posted online. METHODS: UK-based online parenting fora were used to identify discussion threads based around the NCMP between 2010 and 2017. Thirty-one discussion threads from two parent fora were identified. Thematic analysis was used to identify themes in these data. RESULTS: The primary themes identified related to (1) the legitimacy of feedback and judgement from health professionals, (2) the relative importance of collecting population level data above individual preferences, and (3) risks versus benefits of having conversations with children about weight. Most threads adopted an 'argument, counter-argument' format, providing two sides to each issue raised. Information and opinions consistent with public health messages were frequently provided, such as how data are used, that feedback is intended to be helpful, and the importance of collecting national data. There was little evidence of individual parents shifting their views in response to others' arguments. CONCLUSIONS: This study provides novel insight into peer-to-peer debates about the NCMP, including the arguments parents find convincing and acceptable for and against a national programme to weigh children and provide feedback to parents about their weight. Online fora were used as an opportunity to express criticism or distress, but also to seek advice from peers regarding concerns about whether or not to opt-out. Thus, both general issues related to the legitimacy of population screening and outcomes for individual children were of concern to parents.

Interventions to Prevent Cognitive Decline and Dementia in Adults without Cognitive Impairment: A Systematic Review.

Without preventative strategies, the burden of dementia is likely to increase rapidly worldwide. Primary prevention approaches involve modifying risk factors before symptoms of cognitive impairment develop. This review systematically assesses Randomised Controlled Trials (RCTs) and reviews of RCTs for their effectiveness in primary prevention. We searched Medline, the Cochrane Library, Web of Science and Psych-Info for relevant studies using pre-determined keywords. Both non-pharmacological and pharmacological interventions were considered. Inclusion criteria were sample size greater or equal to 50, at least 6 months of follow-up, and participants with no cognitive impairment at baseline. Outcomes included dementia incidence, cognitive decline and cognitive function. Study quality was rated using the Jadad criteria. Thirty-nine studies, 17 non-pharmacological and 22 pharmacological, were included. Results were heterogeneous across interventions and studies, with few significant effects. Studies investigating physical activity and calcium channel blocker treatment demonstrated significant effects in preventing cognitive decline. There were no conclusive results demonstrating overall capacity of assessed interventions to reduce risk of dementia. The review provides an overview of the current literature, and identifies areas in need of further research.

Coronary venous retroperfusion of arterial blood for the treatment of acute myocardial ischemia.

Synchronized coronary venous retroperfusion of autologous arterial blood was offered to patients referred for medically refractory unstable angina or evolving myocardial infarction with contraindications to thrombolytic therapy. Primary endpoints of angina, ST segment deviation, and two-dimensional echocardiographic systolic wall motion were followed to determine the efficacy of retroperfusion in patients prior to and then during angioplasty, surgical intervention, or pharmacological management, as the clinical picture warranted. Over a 12 month period, 21 patients were referred and 15 received retroperfusion. All experienced full relief of angina (p = 0.008). ST segment deviations and systolic wall motion of ischemic zones were observed to improve (p = 0.06 ST changes; p = 0.0001 wall motion changes) with synchronized retrograde perfusion. During attempts to remove patients from retroperfusion, statistically significant (p < 0.01) reproducible changes in these same endpoints were documented. Retroperfusion appears to improve acute myocardial ischemia. This technique functions well in the intensive care unit environment with only fluoroscopy as technical imaging support.

Massive bifrontal epidermoid tumor.

There have been 27 cases of epidermoid tumor reported to arise from the frontal or ethmoid sinus area. We report the case of a virtually asymptomatic massive bifrontal epidermoid tumor arising from the ethmoid sinus in a 76-year-old male.

Restriction endonuclease analysis of Marek's disease virus DNA: differentiation of viral strains and determination of passage history.

The restriction endonuclease (RE) patterns of DNA from serotype 1 Marek's disease viruses (MDVs) are unique to serotype 1 viruses and can also be used to differentiate between low and high cell-culture-passaged viruses. We compared the RE patterns of DNA from seven serotype 2 and 3 MDVs before and after serial in vitro passage. Passage of four serotype 2 strains resulted in a variety of changes in the RE pattern. Individual strains within a serotype exhibited unique restriction patterns that allowed individual isolates to be differentiated. In a similar manner, the serotype 3 virus strains displayed RE pattern variations that were unique to each strain, as well as differences between low and high cell-culture passage. Our findings, together with earlier reports, suggest that the RE patterns of MDV DNA provide a simple and accurate method to: 1) differentiate between the three MDV serotypes, 2) differentiate between virus strains within a serotype, and 3) determine whether the viruses have been passaged extensively in cell culture.

Therapy of ischemic cardiomyopathy with pentoxifylline.

Abnormal blood rheology is a known characteristics of coronary artery disease. The authors evaluated the effects of pentoxifylline on the exercise capacity ejection fraction and symptoms of 9 patients with ischemic cardiomyopathy. All patients had signs and symptoms of left ventricular dysfunction. All had at least two major vessels obstructed as determined by coronary angiography. Pentoxifylline 400 mg three times daily was administered for twelve weeks. Seven of 9 patients responded with increases in ejection fraction and exercise tolerance. Exercise tolerance correlated with improvement or lack of improvement in ejection fraction. For all patients at twelve weeks post-therapy mean ejection fraction increased 9.8% over baseline (p = .07), total treadmill time increased 15% (p = .27), and mean double product increased 13% (p = .03). Anginal symptoms were significantly improved over baseline at twelve weeks of therapy (p greater than .001), as well as dyspnea on exertion (p = .03). Pentoxifylline was well tolerated. Pentoxifylline may benefit ischemic cardiomyopathy by improving coronary perfusion owing to favorable alterations in hemorheologic properties.

Guiding catheter exchange during coronary angioplasty.

A new technique to exchange one angioplasty guiding catheter for another with the guide wire in place and across a coronary artery stenosis has been developed to decrease the dangers of having to recross the stenosis with a guide wire. This technique utilizes a regular extended angioplasty guide wire and enables the exchange of guiding catheters during the angioplasty procedure. In 683 consecutive angioplasty procedures by one operator, this technique has been attempted 57 times in 43 patients (6.3%) and has been successful 51 times (90%). The only failures were when the second catheter had a large or open curve (left Amplatz II, 5/22 unsuccessful or multipurpose, 1/3 unsuccessful). There have been no complications. We conclude that exchange of a guiding catheter over a guide wire by the method described is safe and helpful in cases where different guiding catheters are needed for back-up power once the lesion has been crossed with a guide wire.

Short-term control of supraventricular tachycardia with verapamil infusion and calcium pretreatment.

Nineteen consecutive patients with atrial fibrillation/flutter or other types of supraventricular tachycardia were given intravenous (IV) calcium salts (1 g) followed by verapamil infusion at a rate of 1 mg/min. Successful treatment was defined as control of ventricular response to less than or equal to 100 beats per minute (bpm) or conversion to sinus mechanism in patients with atrial arrhythmias: 11 patients had atrial fibrillation; three had atrial flutter; four had reentrant supraventricular tachycardias (SVT); and one had paroxysmal SVT. Therapy was successful in all patients. The mean dose of verapamil required to achieve desired outcome was 20 mg. Heart rate showed no significant change as a result of calcium pretreatment (160 bpm v 151 bpm). However, heart rate was significantly decreased, to 95 bpm, after treatment with verapamil. Blood pressure showed no change from baseline with either calcium or verapamil therapy. Verapamil infusion following IV calcium successfully treats atrial fibrillation/flutter or SVTs without depressing systemic blood pressure.

[Implantation of mitral valve prosthesis with continuos suture]. / Colocación de prótesis mitrales con sutura continua.

The results obtained in 20 patients with the use of continue suture technic for prosthetic implantation of the mitral valve were compared to those observed in other 20 patients in which the prothesis were implanted with isolated suture technic. With the first one the aortic clamp time was reduced in average about 50 minutes; the extracorporeal circulation time also diminished in the same proportion. One patient died in each group, meaning a 5% of hospital mortality. The going after time in the first group was 2.5 years and in none was found prosthetic dysfunction or perivalvular lickage. We conclude that prosthetic implantation technic for mitral valve with continue suture, offers the following advantages: a) Important reduction of the transoperative myocardial ischemia. b) Reduction also, of the hole estracorporeal circulation time. c) Minor possibilities of periprosthetic lickage. d) Minor risk of valvular thrombosis in the suture line.
