Financial interests of patient organisations contributing to technology appraisal at England's National Institute for Health and Care Excellence (NICE): a policy review

Objectives: To investigate the prevalence of financial interests among patient organisations contributing to health technology assessment at the National Institute for Health and Care Excellence (NICE) in England, and the extent to which current disclosure policy ensures decision-making committees are aware of these interests. Design: Policy review using annual accounts, reports and websites of patient organisations, a database of payments declared by pharmaceutical manufacturers (Disclosure UK), other manufacturer declarations, responses from patient organisations, and declarations of interests by nominated representatives of patient organisations. Setting: Appraisals of medicines and treatments for use in the English and Welsh National Health Service. Participants: 53 patient organisations contributing to 41 NICE technology appraisals published in 2015 and 2016, with 117 separate occasions that a patient organisation contributed to the appraisal of a technology. Main outcome measures: (i) Prevalence of specific interests, i.e. funding from manufacturer(s) of a technology under appraisal or competitor products; (ii) Proportion of specific interests of which NICE decision-making committees were aware; (iii) Proportion of specific interests for which disclosure was not required by current NICE policy. Results: 38/53 (71.7%) patient organisations had accepted funding from the manufacturer(s) of a technology or a competitor product in the same or previous year that they had contributed to the appraisal of that technology. Specific interests were 46 present on 92 out of 117 (78.6%) occasions that patient organisations contributed to appraisals in 2015 and 2016. NICE decision-making committees were aware of less than a third of specific interests (36/115, 31.3%). For over half of the specific interests of which committees were unaware (42/79, 53.2%), disclosure by patient organisations was not required by current NICE policy. Conclusions: Specific interests are highly prevalent among patient organisations contributing to health technology assessment. NICE is reviewing its disclosure policy to ensure that decision-making committees are aware of all relevant interests

Using social networking sites for communicable disease control: innovative contact tracing or breach of confidentiality?

Social media applications such as Twitter, YouTube and Facebook have attained huge popularity, with more than three billion people and organizations predicted to have a social networking account by 2015. Social media offers a rapid avenue of communication with the public and has potential benefits for communicable disease control and surveillance. However, its application in everyday public health practice raises a number of important issues around confidentiality and autonomy. We report here a case from local level health protection where the friend of an individual with meningococcal septicaemia used a social networking site to notify potential contacts

The Effect Of Problem Based Learning On Undergraduate Oral Communication Competency

Purpose:  The aim of this study was to ascertain the effect of Problem Based Learning (PBL) on student oral communication competency gains. Methods:  Eighty students from two consecutive undergraduate Kinesiology courses (Spring semesters, 2014-15) formed into 29 small groups and were studied.  Oral communication competency was assessed using a customized rubric and digital recordings of student presentations.  Changes to oral communication competency across time were tested using a dependent t-test; a < .05. Results:  Significant inter-rater agreement was found at both time points for oral communication rating, and student groups demonstrated significant oral communication gains across time.  Conclusions:  Collaborative learning was shown to improve students’ oral communication competency. Future study is required to determine the influence of student motivation and goal orientation on oral communication competency, in relation to the various phases of knowledge creation occurring within student groups.

The political views of doctors in the United Kingdom: A cross sectional study

Background: Little is known about the political views of doctors in the United Kingdom, despite their importance in the functioning of the National Health Service. Methods: Survey-based cross-sectional study in which we asked questions about voting behaviour in 2015 and 2017 UK general elections and 2016 referendum on leaving the European Union (Brexit) and questions relating to recent health policies. Results: 1,172 doctors (45.1% women) from 1,295 responded to an online survey. 60.5% described their political views as ‘left-wing’ and 62.2% described themselves as ‘liberal’. 79.4% of respondents voted to remain in the EU in the 2016 referendum compared to 48.1% of voters as a whole (χ2=819.8, p<0.001). 98.6% of respondents agreed that EU nationals working in the NHS should be able to remain in the UK after Brexit. The median score for the impact of Brexit on the NHS on a scale of 0 (worst impact) to 10 (best impact) was 2 (IQR=1-4). Most respondents agreed with the introduction of minimum alcohol pricing in the UK (73.9%), charging patients who are not eligible for NHS treatment for non-urgent care (70.6%) and protecting a portion of national spending for the NHS (87.1%). 65.8% thought there was too much use of NHS-funded private sector provision in their medical practice. Specialty, income and grade were associated with divergent opinions. Conclusions: UK doctors are left-leaning and liberal in general, which is reflected in their opinions on topical health policy issues. Doctors in the UK voted differently from the general electorate in recent polls

Estimating brain volume loss after radiation therapy in children treated for posterior fossa tumors (Corpus callosum and whole brain volume changes following radiotherapy in children).

Background More than half of pediatric tumors of central nervous system (CNS) primarily originate in the posterior fossa and are conventionally treated with radiation therapy (RT).Objectives The objective of this study was to establish whether corpus callosum volumes (CCV) and whole brain volumes (WBV) are correlated and to determine the impact of whole-brain lowvs high-dose RT on brain parenchymal volume loss as assessed using each technique.Material and methods Of the 30 identified children (6-12 years) with newly diagnosed posterior fossa tumors treated with cranial RT, including focal and whole-brain RT, suitable imaging was obtained for 23. Radiotherapy regimens were the following: no whole-brain RT (Group 1, n = 7), low-dose whole-brain RT (30 Gy, Group 3, n = 7) in addition to focal boost. Magnetic resonance images (MRIs) were analyzed at baseline and follow-up (median 14 months). The CCVs were manually segmented on midline sagittal slice (n = 23), while WBVs were segmented semi-automatically using Freesurfer (n = 15). This was done twice (6-month interval) for all baseline CCV measurements and 5 randomly selected WBV measurements to establish measurement reproducibility. Correlations between CCV and WBV were investigated and percentage of children demonstrating reduction in CCV or WBV noted.Results Correlation between baseline CCV and WBV was not significant (p = 0.37). Measurement reproducibility was from 6% to -9% for CCV and from 4.8% to -1.2% for WBV. Among the children studied, 30.4% (7/23) had >9% reduction in CCV at follow-up, while 33.3% (5/15) had >1.2% reduction in WBV. Five of 7 patients with CCV loss were not picked up by WBV measurements. Similarly, 3 of 5 patients with WBV loss were not picked up by CCV measurements.Conclusions The CCV and the WBV are unrelated and may indicate different brain parenchymal losses following RT. Up to a third of posterior fossa tumors treated with RT have measurable CCV or WBV loss; incidence was equivalent in lowvs high-dose whole-brain RT

‘ReConnect’: a model for working with persistent pain patients on improving sexual relationships

Introduction: Many individuals with persistent pain experience difficulties with sexual function which are exacerbated by avoidance and anxiety. Due to embarrassment or shame, sexual activity may not be identified as a goal for pain management programmes (PMPs). In addition, clinicians can feel that they lack skills and confidence in addressing these issues. Methods: We sought to develop a biopsychosocial model for helping patients return to sexual activity and manage relationships in the context of pain management, known as ‘ReConnect’. The model amalgamates well-established methods from pain management and sex therapy to guide multidisciplinary team members. ReConnect comprises three components: (1) ‘cognitive and myth-busting’, (2) ‘sensations and feelings’ and (3) ‘action-experimentation’. We collected self-report data from 281 women and 92 men from our specialist PMP for chronic abdomino-pelvic. pain, including questions measuring interference with and avoidance of sex due to pain, and the Multi-dimensional Sexuality Questionnaire (MSQ) to measure anxiety about sexual activity. Results: The results show statistically significant improvements for anxiety, avoidance of sex and sexual interference. Using the ReConnect model to structure clinical work, pain management clinicians reported increased confidence in addressing sexual activity goals. Conclusion: By using the ReConnect model is a framework for clinicians to use to support sexual activity goals. It has demonstrated improvements in clinical outcomes such as anxiety around sex and interference of pain in sexual activity. We encourage its application in pain management services in both one-to-one and group sessions, as a method for encouraging pain patients to address this important area of life which can be adversely affected by pain

Shock wave lithotripsy targeting of the kidney and pancreas does not increase the severity of metabolic syndrome in a porcine model

PURPOSE: We determined whether shock wave lithotripsy of the kidney of pigs with metabolic syndrome would worsen glucose tolerance or increase the risk of diabetes mellitus. MATERIALS AND METHODS: Nine-month-old female Ossabaw miniature pigs were fed a hypercaloric atherogenic diet to induce metabolic syndrome. At age 15 months the pigs were treated with 2,000 or 4,000 shock waves (24 kV at 120 shock waves per minute) using an unmodified HM3 lithotripter (Dornier MedTech, Kennesaw, Georgia). Shock waves were targeted to the left kidney upper pole calyx to model treatment that would also expose the pancreatic tail to shock waves. The intravenous glucose tolerance test was done in conscious fasting pigs before lithotripsy, and 1 and 2 months after lithotripsy with blood samples taken for glucose and insulin measurement. RESULTS: Pigs fed the hypercaloric atherogenic diet were obese, dyslipidemic, insulin resistant and glucose intolerant, consistent with metabolic syndrome. Assessments of insulin resistance, glucose tolerance and pancreatic β cell function from fasting plasma glucose and insulin levels, and the glucose and insulin response profile to the intravenous glucose tolerance test were similar before and after lithotripsy. CONCLUSIONS: The metabolic syndrome status of pigs treated with shock wave lithotripsy was unchanged 2 months after kidney treatment with 2,000 high amplitude shock waves or overtreatment with 4,000 high amplitude shock waves. These findings do not support a single shock wave lithotripsy treatment of the kidney as a risk factor for the onset of diabetes mellitus

A Measurement of the Interference Structure Function, R_LT, for the 12C(e,e'p) reaction in the Quasielastic Region

The coincidence cross-section and the interference structure function, R_LT, were measured for the 12C(e,e'p) 11B reaction at quasielastic kinematics and central momentum transfer of q=400 MeV/c. The measurement was at an opening angle of theta_pq=11 degrees, covering a range in missing energy of E_m = 0 to 65 MeV. The R_LT structure function is found to be consistent with zero for E_m > 50 MeV, confirming an earlier study which indicated that R_L vanishes in this region. The integrated strengths of the p- and s-shell are compared with a Distorted Wave Impulse Approximation calculation. The s-shell strength and shape are compared with a Hartree Fock-Random Phase Approximation calculation. The DWIA calculation overestimates the cross sections for p- and s-shell proton knockout as expected, but surprisingly agrees with the extracted R_LT value for both shells. The HF-RPA calculation describes the data more consistently, which may be due to the inclusion of 2-body currents in this calculation.Comment: 8 Pages LaTex, 5 postscript figures. Submitted to Phys.

The Influence of Moderate Hypercapnia on Neural Activity in the Anesthetized Nonhuman Primate

Hypercapnia is often used as vasodilatory challenge in clinical applications and basic research. In functional magnetic resonance imaging (fMRI), elevated CO2 is applied to derive stimulus-induced changes in the cerebral rate of oxygen consumption (CMRO2) by measuring cerebral blood flow and blood-oxygenation-level–dependent (BOLD) signal. Such methods, however, assume that hypercapnia has no direct effect on CMRO2. In this study, we used combined intracortical recordings and fMRI in the visual cortex of anesthetized macaque monkeys to show that spontaneous neuronal activity is in fact significantly reduced by moderate hypercapnia. As expected, measurement of cerebral blood volume using an exogenous contrast agent and of BOLD signal showed that both are increased during hypercapnia. In contrast to this, spontaneous fluctuations of local field potentials in the beta and gamma frequency range as well as multiunit activity are reduced by ∼15% during inhalation of 6% CO2 (pCO2 = 56 mmHg). A strong tendency toward a reduction of neuronal activity was also found at CO2 inhalation of 3% (pCO2 = 45 mmHg). This suggests that CMRO2 might be reduced during hypercapnia and caution must be exercised when hypercapnia is applied to calibrate the BOLD signal
