Feasibility of outpatient daycase local anaesthestic Rezūm™ without sedation

Background Rezūm™ is a relatively new bladder outflow obstruction (BOO) procedure that uses thermal energy through water vapour to cause necrosis of prostatic tissue. The standard delivery of this treatment is in an operating theatre under a general or spinal anaesthetic, or under local anaesthetic with sedation that requires patient monitoring. Methods We propose an outpatient daycase method of delivering Rezūm™ under local anaesthetic without sedation, using a prostatic local anaesthetic block and cold local anaesthetic gel instillation into the urethra. Results Preliminary results of our first thirteen patients demonstrate the feasibility of this new technique, with a mean pain score of 2.1 out of 10 on a visual analogue scale, a successful trial without catheter in all 13 patients (one patient voided successfully on second trial), a reduction in mean International Prostate Symptom Score (IPSS) from 20.6 to 5.4, and improvement in maximum flow from 8.8 ml/s to 14.4 ml/s. The complications were minor (Clavien-Dindo less than III) and included a UTI, minor bleeding not requiring admission, and retrograde ejaculation. Conclusions We demonstrate that an outpatient local anaesthetic daycase service without sedation is feasible. This can be delivered in a clinic setting, reduce waiting times for BOO surgery, and increase availability of operating theatre for other general anaesthetic urological procedures.Peer reviewe

Global development of children’s palliative care: the picture in 2017

Background: The growing interest in tracking the global development of palliative care provision is not matched by research on the development of palliative care services specifically for children. Yet it is estimated that worldwide, 21 million children annually could benefit from the provision of palliative care. We report on a global study of children’s palliative care development and offer suggestions for further improvement in design and method. Methods: Primary data on the level of children’s palliative care development in 2017 was collected from in-country experts through a specific question in an online questionnaire that sought to measure the overall level of palliative care provision globally. Countries were assigned to one of six categories on the basis of the responses obtained. Conflicting responses from the same country were resolved with reference to a hierarchy of preferred respondents. Results: Our data allowed the categorisation of 113 countries, accounting for 65% of the global population aged under 20. Number of countries (% of global child population) in each category were as follows: 1) no known activity, 21 (4%); 2) capacity-building, 16 (24%); 3a) isolated provision, 55 (30%); 3b) generalized provision, 5 (1%); 4a) preliminary integration into mainstream provision, 14 (8%); 4b) advanced integration, 7 (2%). Conclusions: Children’s palliative care at the highest level of provision is available in just 21 countries, accounting for fewer than 10% of the global population aged under 20. It is concentrated in high income settings, whilst the majority of the global need for such care is in low- and middle-income countries. Our study is a useful tool for global advocacy relating to children’s palliative care and a stimulus for the creation of improved indicators to measure it at the country level

Acute plate fixation of displaced midshaft clavicular fractures is not associated with earlier return of normal shoulder function when union is achieved

Aims: It is unclear whether acute plate fixation facilitates earlier return of normal shoulder function following a displaced mid-shaft clavicular fracture compared with nonoperative management when union occurs. The primary aim of this study was to establish whether acute plate fixation was associated with a greater return of normal shoulder function when compared with nonoperative management in patients who unite their fractures. The secondary aim was to investigate whether there were identifiable predictors associated with return of normal shoulder function in patients who achieve union with nonoperative management. Methods: Patient data from a randomized controlled trial were used to compare acute plate fixation with nonoperative management of united fractures. Return of shoulder function was based on the age- and sex-matched Disabilities of the Arm, Shoulder and Hand (DASH) scores for the cohort. Independent predictors of an early recovery of normal shoulder function were investigated using a separate prospective series of consecutive nonoperative displaced mid-shaft clavicular fractures recruited over a two-year period (aged ≥ 16 years). Patient demographics and functional recovery were assessed over the six months post-injury using a standardized protocol. Results: Data from the randomized controlled trial consisted of 86 patients who underwent operative fixation compared with 76 patients that united with nonoperative treatment. The recovery of normal shoulder function, as defined by a DASH score within the predicted 95% confidence interval for each respective patient, was similar between each group at six weeks (operative 26.7% vs nonoperative 25.0%, p = 0.800), three months (52.3% vs 44.2%, p = 0.768), and six months post-injury (86.0% vs 90.8%, p = 0.349). The mean DASH score and return to work were also comparable at each timepoint. In the prospective cohort, 86.5% (n = 173/200) achieved union by six months post-injury (follow-up rate 88.5%, n = 200/226). Regression analysis found that no specific patient, injury, or fracture predictor was associated with an early return of function at six or 12 weeks. Conclusion: Return of normal shoulder function was comparable between acute plate fixation and nonoperative management when union was achieved. One in two patients will have recovery of normal shoulder function at three months, increasing to nine out of ten patients at six months following injury when union occurs, irrespective of initial treatment

Lived experiences of gaming and gambling related harm and implications for healthcare services

Children and young people (CYP) are high consumers of loot boxes, raising concerns about the impact of a convergence of gaming and gambling-related harms and their potential negative developmental outcomes in adulthood. Especially, given evidence that practitioners and parents/carers are lacking awareness of the risks of converging gaming-gambling environments. Addressing these risks necessitates understanding the experiences of gaming and gambling-related harm within healthcare systems. This study aimed to gain insights from individuals with previous lived experience of gaming and/or gambling-related harm in the context of CYP and healthcare systems. A qualitative design was adopted using two semi-structured online focus groups, involving five participants with previous lived experience of gaming and/or gambling-related harm. Focus groups explored their experiences of healthcare services and barriers to support in the journey through harm and recovery. Thematic analysis of the data revealed five key themes: i) Escapism; ii) Identity; iii) Preventative Education; iv) Safer Environments; v) Health-based Narratives. Results suggested a convergence of gaming and gambling-related harm in terms of patterns of experiences of escapism and internalising harm with identity, highlighting the need for safer environments and preventative approaches to protect CYP against novel risks of harm through healthcare systems. The results suggest that preventative approaches need to understand the virtual worlds of CYP and the importance of digital resilience. Implications for practitioners, services, policy makers, and regulators seeking to protect CYP from the risks of gaming and gambling-related harm are discussed

Mapping levels of Palliative Care development in 198 Countries: the situation in 2017

Context Palliative care is gaining ground globally and is endorsed in high-level policy commitments, but service provision, supporting policies, education, and funding are incommensurate with rapidly growing needs. Objectives The objective of this study was to describe current levels of global palliative care development and report on changes since 2006. Methods An online survey of experts in 198 countries generated 2017 data on 10 indicators of palliative care provision, fitted to six categories of development. Factor analysis and discriminant analysis showed the validity of the categorization. Spearman correlation analyses assessed the relationship with World Bank Income Level (WBIL), Human Development Index (HDI), and Universal Health Coverage (UHC). Results Numbers (percentages) of countries in each development category were as follows: 1) no known palliative care activity, 47 (24%); 2) capacity-building, 13 (7%); 3a) isolated provision, 65 (33%); 3b) generalized provision, 22 (11%); 4a) preliminary integration into mainstream provision, 21 (11%); 4b) advanced integration, 30 (15%). Development levels were significantly associated with WBIL (rS = 0.4785), UHC (rS = 0.5558), and HDI (rS = 0.5426) with P < 0.001. Net improvement between 2006 and 2017 saw 32 fewer countries in Categories 1/2, 16 more countries in 3a/3b, and 17 more countries in 4a/4b. Conclusion Palliative care at the highest level of provision is available for only 14% of the global population and is concentrated in European countries. An 87% global increase in serious health-related suffering amenable to palliative care interventions is predicted by 2060. With an increasing need, palliative care is not reaching the levels required by at least half of the global population

Tracer diffusion in granular shear flows

Tracer diffusion in a granular gas in simple shear flow is analyzed. The analysis is made from a perturbation solution of the Boltzmann kinetic equation through first order in the gradient of the mole fraction of tracer particles. The reference state (zeroth-order approximation) corresponds to a Sonine solution of the Boltzmann equation, which holds for arbitrary values of the restitution coefficients. Due to the anisotropy induced in the system by the shear flow, the mass flux defines a diffusion tensor $D_{ij}$ instead of a scalar diffusion coefficient. The elements of this tensor are given in terms of the restitution coefficients and mass and size ratios. The dependence of the diffusion tensor on the parameters of the problem is illustrated in the three-dimensional case. The results show that the influence of dissipation on the elements $D_{ij}$ is in general quite important, even for moderate values of the restitution coefficients. In the case of self-diffusion (mechanically equivalent particles), the trends observed in recent molecular dynamics simulations are similar to those obtained here from the Boltzmann kinetic theory.Comment: 5 figure
