The volume and the distribution of premorbid white matter hyperintensities: Impact on post-stroke aphasia

White matter hyperintensities (WMH) are a radiological manifestation of progressive white matter integrity loss. The total volume and distribution of WMH within the corpus callosum have been associated with pathological cognitive ageing processes but have not been considered in relation to post-stroke aphasia outcomes. We investigated the contribution of both the total volume of WMH, and the extent of WMH lesion load in the corpus callosum to the recovery of language after first-ever stroke. Behavioural and neuroimaging data from individuals (N = 37) with a left-hemisphere stroke were included at the early subacute stage of recovery. Spoken language comprehension and production abilities were assessed using word and sentence-level tasks. Neuroimaging data was used to derive stroke lesion variables (volume and lesion load to language critical regions) and WMH variables (WMH volume and lesion load to three callosal segments). WMH volume did not predict variance in language measures, when considered together with stroke lesion and demographic variables. However, WMH lesion load in the forceps minor segment of the corpus callosum explained variance in early subacute comprehension abilities (t = -2.59, p = .01) together with corrected stroke lesion volume and socio-demographic variables. Premorbid WMH lesions in the forceps minor were negatively associated with early subacute language comprehension after aphasic stroke. This negative impact of callosal WMH on language is consistent with converging evidence from pathological ageing suggesting that callosal WMH disrupt the neural networks supporting a range of cognitive functions.

95 EXPLORING HIP FRACTURE OUTCOMES IN POST-ACUTE REHABILITATION: A MULTI-SITE AUDIT

Background

In 2020, 28% of all hip fractures in Ireland were discharged to off-site rehabilitation. The annual Irish Hip Fracture Database (IHFD) report captures patient outcomes at the point of acute discharge however patient outcomes at discharge from offsite rehabilitation are unknown.

Methods

A multi-site retrospective audit was completed examining hip fracture outcomes for patients admitted to four post-acute rehabilitation hospitals during 2021, using IHFD HIPE portals as well as local databases. Descriptive statistics including demographics, pre-fracture mobility as well as outcomes measured including acute length of stay, rehabilitation length of stay, discharge destination and independence with mobility on discharge from rehabilitation. A comparison analysis between sites was completed.

Results

A total of 445 patients were admitted post hip fracture to the four rehabilitation hospitals in 2021. Most were female (69%, n=307), mean age 82.5, 49% lived alone and most (55%) had low pre-fracture mobility as measured by New Mobility Score of 0-6. The mean acute length of stay was 11.8 days and rehabilitation stay 37.6 days. Most (90.2% of complete data, n=333) discharged home, 4.5% (n=17) were transferred to hospital, 3.2% (n=12) were newly admitted to nursing home and 1% (n=4) died. Most (82.2% of complete data, n=256) were independently mobile (CAS 6) at discharge from rehabilitation. There was no significant difference in patient profile between sites however there were significant difference in both acute length of stay (median range 8-13days) as well as rehabilitation length of stay (median range 16-39days).

Conclusion

The findings of this audit provide a new perspective on recovery post hip fracture and insight into longer term hip fracture outcomes. It shows that data collection is feasible in off-site rehabilitation units and should be considered for inclusion in the IHFD. Further work could explore the establishment of standards of care in the post-acute phase of hip fracture rehabilitation.

A case series of paediatric patients with spinal muscular atrophy type I undergoing scoliosis correction surgery

Spinal muscular atrophy is a neuromuscular disorder with degeneration of spinal motor neurons. Type I is a severe variant that was recently shown to be amenable to treatment with the antisense oligonucleotide nusinersen. As a result of increased life expectancy with this treatment, more children with spinal muscular atrophy type I are presenting for spinal correction surgery. In this case series, we present four such patients who underwent spinal surgery at our institution over the course of one year. Pre-operative assessment showed evidence of reduced respiratory function requiring nocturnal non-invasive ventilation in all four patients. A difficult airway was encountered in two of the four patients. Postoperative complications were ubiquitous and included CSF leak, poor wound healing, metal frame exposure, frame instability and wound infection. There were no postoperative respiratory complications and all four children returned to their respiratory baseline postoperatively. All patients underwent successful lumbar puncture and intrathecal nusinersen injection following their spinal surgeries. Given the risk of complications and prolonged recovery following spinal surgery, a detailed family discussion is advisable.

Qutrit Randomized Benchmarking

Ternary quantum processors offer significant potential computational advantages over conventional qubit technologies, leveraging the encoding and processing of quantum information in qutrits (three-level systems). To evaluate and compare the performance of such emerging quantum hardware it is essential to have robust benchmarking methods suitable for a higher-dimensional Hilbert space. We demonstrate extensions of industry standard randomized benchmarking (RB) protocols, developed and used extensively for qubits, suitable for ternary quantum logic. Using a superconducting five-qutrit processor, we find an average single-qutrit process infidelity of 3.8×10^{-3}. Through interleaved RB, we characterize a few relevant gates, and employ simultaneous RB to fully characterize crosstalk errors. Finally, we apply cycle benchmarking to a two-qutrit CSUM gate and obtain a two-qutrit process fidelity of 0.85. Our results present and demonstrate RB-based tools to characterize the performance of a qutrit processor, and a general approach to diagnose control errors in future qudit hardware.

Health-related quality of life in women after colposcopy: results from a longitudinal patient survey

BACKGROUND

Information concerning the health-related quality-of-life (HRQoL) consequences of colposcopy is limited, particularly over time. In a longitudinal study, we investigated women's HRQoL at 4, 8 and 12 months post colposcopy and the factors associated with this.

METHODS

Women attending colposcopy at two large hospitals affiliated with the national screening programme in Ireland were invited to complete questionnaires at 4, 8 and 12 months post colposcopy. HRQoL was measured using the EQ-5D-3L and compared across a range of socio-demographic, clinical and attitudinal variables. A mixed-effects logistic multivariable model was employed to investigate associations between these variables and low HRQoL.

RESULTS

Of 584 women initially recruited, 429, 343 and 303 completed questionnaires at 4, 8 and 12 months, respectively. The mean overall HRQoL score for the sample across all time points was 0.90 (SD 0.16). Approximately 18% of women experienced low HRQoL at each of the three time points. In multivariable testing, over the entire 12-month follow-up period, non-Irish nationals (OR 8.99, 95% CI 2.35-34.43) and women with high-grade referral cytology (OR 2.78, 95% CI 1.08-7.13) were at higher odds of low HRQoL. Women who were past (OR 0.20, 95% CI 0.07-0.58) or never (OR 0.42, 95% CI 0.16-1.12) smokers were at lower odds of low HRQoL than current smokers. As women's satisfaction with their healthcare increased their odds of experiencing low HRQoL fell (OR per unit increase 0.51, 95% CI 0.34-0.75).

CONCLUSIONS

Women's HRQoL did not change over the 12 months post colposcopy, but some subgroups of women were at higher risk of experiencing low HRQoL. These subgroups may benefit from additional support.

Professional continuous glucose monitoring and endocrinology eConsult for adults with type 2 diabetes in primary care: Results of a clinical pilot program

Background

Limitations in access to specialty diabetes care exist. Endocrinology eConsult that integrates professional continuous glucose monitoring (CGM-enhanced eConsult) may improve healthcare delivery, but has yet to be evaluated. We implemented a pilot program for patients with type 2 diabetes (T2DM) managed by primary care clinical pharmacists using CGM-enhanced eConsult and evaluated the acceptability and clinical outcomes in comparison to routine in-person endocrinology consultation.

Methods

Seventy-four adult patients with established T2DM (age 18-65) were included. Twenty-nine were seen in-person by endocrinology and 45 were seen by pharmacists in primary care. Thirteen patients were referred for CGM-enhanced eConsult. Acceptability was assessed with pre/post clinician acceptability questionnaires and patient assessment of perceived burden. Clinical outcomes included time to first specialty appointment, baseline and 3-month follow-up HbA1c, and antihyperglycemic medication use.

Results

There were no differences in patient acceptability of the CGM-enhanced eConsult as compared to endocrinology referral or pharmacy care. At baseline, all patients referred for eConsult were prescribed insulin. Three-month glycemic outcomes were comparable, with HbA1c reduction 1% + 2% in endocrinology, 1.5% + 1.1% with CGM-enhanced eConsult, and 1.6% + 1.8% in clinical pharmacy (p = 0.19). Time to an initial diabetes visit with a pharmacist was significantly shorter than with endocrinology, 20 days (IQR 26) for pharmacy vs. 45 days (IQR 54) for endocrinology, (p = 0.0001).

Conclusions

CGM-enhanced eConsult resulted in more timely access to endocrinology expertise, was acceptable to patients, and resulted in similar short-term glycemic outcomes compared to in-person consultation. Effectiveness of CGM-enhanced eConsults should be further explored.

A multi institutional comparison of imaging dose and technique protocols for neonatal chest radiography

INTRODUCTION

The focus on paediatric radiation dose reduction supports reevaluation of paediatric imaging protocols. This is particularly important in the neonates where chest radiographs are frequently requested to assess respiratory illness and line placement. This study aims to assess the impact of neonatal chest radiographic protocols on patient dose in four hospitals in different countries.

METHODS

Exposure parameters, collimation, focus to skin distance (FSD) and radiation dose from 200 neonatal chest radiographs were registered prospectively. Inclusion criteria consisted of both premature and full-term neonates weighing between 1000 and 5000 g. Only data from the examinations meeting diagnostic criteria and approved for the clinical use were included. Radiation dose was assessed using dose area product (DAP).

RESULTS

The lowest DAP value (4.58 mGy cm²) was recorded in the Norwegian hospital, employing a high kVp, low mAs protocol using a DR system. The Canadian hospital recorded the highest DAP (9.48), using lower kVp and higher mAs with a CR system, including the addition of a lateral projection. The difference in the mean DAP, weight, field of view (FOV) and kVp between the hospitals is statistically significant (p < 0.001).

CONCLUSION

Use of non-standardised imaging protocols in neonatal chest radiography results in differences in patient dose across hospitals included in the study. Using higher kVp, lower mAs and reducing the number of lateral projections to clinically relevant indications result in a lower DAP measured in the infant sample studied. Further studies to examine image quality based on exposure factors and added filtration are recommended.

IMPLICATIONS FOR PRACTICE

Reevaluation of paediatric imaging protocols presents an opportunity to reduce patient dose in a population with increased sensitivity to ionising radiation.

Effectiveness of Video Modeling in Children With Autism Spectrum Disorder (ASD), Pretest-Posttest

Date Presented 04/04/19

This study evaluated the effectiveness of video modeling as an intervention tool to teach children with autism spectrum disorder (ASD) to independently don a jacket. The seven participants viewed a video recording of a model demonstrating how to don a jacket once daily for two weeks. Their performance was assessed using a pretest-posttest design. The results showed a statistically significant difference (p &lt;.01), indicating that video modeling was an effective intervention tool.

Fabricated facial rash - an unusual presentation of factitious disorder

Patients with factitious disorder typically present with signs or symptoms suggesting a medical problem, but which transpire to be self-induced or fabricated. Repeated investigations and treatments are often carried out to no avail before this possibility is considered. In this case, a 51-year-old female presented to the oral and maxillofacial surgery unit with toothache and a facial rash. Following admission to hospital a range of investigations were performed, and a tooth was extracted. Judicious attention by nursing staff led to the discovery that the patient had been applying make-up to mimic a skin rash. This concern was raised with the patient and she admitted falsifying the rash. Although this patient may have been experiencing pain, by applying make-up in this manner she sought to exaggerate the severity of her condition and as a result underwent potentially unnecessary procedures. This case provides a reminder that the possibility of factitious disorder should be considered in cases where patients present with symptoms or signs which appear fabricated or self-inflicted, defy anatomical or physiological principles, or do not correlate with the history. Thorough history taking is essential, and access to electronic care records may be informative. Psychiatric follow-up is recommended, but not all patients are willing to engage with this process.

'Care and Prevent': rationale for investigating skin and soft tissue infections and AA amyloidosis among people who inject drugs in London

BACKGROUND

Skin and soft tissue infections (SSTIs) are a leading cause of morbidity and mortality among people who inject drugs (PWID). International data indicate up to one third of PWID have experienced an SSTI within the past month. Complications include sepsis, endocarditis and amyloid A (AA) amyloidosis. AA amyloidosis is a serious sequela of chronic SSTI among PWID. Though there is a paucity of literature reporting on AA amyloidosis among PWID, what has been published suggests there is likely a causal relationship between AA amyloidosis and injecting-related SSTI. If left untreated, AA amyloidosis can lead to renal failure; premature mortality among diagnosed PWID is high. Early intervention may reverse disease. Despite the high societal and individual burden of SSTI among PWID, empirical evidence on the barriers and facilitators to injecting-related SSTI prevention and care or the feasibility and acceptability of AA amyloidosis screening and treatment referral are limited. This study aims to fill these gaps and assess the prevalence of AA amyloidosis among PWID.

METHODS

Care and Prevent is a UK National Institute for Health Research-funded mixed-methods study. In five phases (P1-P5), we aim to assess the evidence for AA amyloidosis among PWID (P1); assess the feasibility of AA amyloidosis screening, diagnostic and treatment referral among PWID in London (P2); investigate the barriers and facilitators to AA amyloidosis care (P3); explore SSTI protection and risk (P4); and co-create harm reduction resources with the affected community (P5). This paper describes the conceptual framework, methodological design and proposed analysis for the mixed-methods multi-phase study.

RESULTS

We are implementing the Care and Prevent protocol in London. The systematic review component of the study has been completed and published. Care and Prevent will generate an estimate of AA amyloidosis prevalence among community recruited PWID in London, with implications for the development of screening recommendations and intervention implementation. We aim to recruit 400 PWID from drug treatment services in London, UK.

CONCLUSIONS

Care and Prevent is the first study to assess screening feasibility and the prevalence of positive proteinuria, as a marker for AA amyloidosis, among PWID accessing drug treatment services. AA amyloidosis is a serious, yet under-recognised condition for which early intervention is available but not employed.

Physical after-effects of colposcopy and related procedures, and their inter-relationship with psychological distress: a longitudinal survey

OBJECTIVE

To estimate prevalence of post-colposcopy physical after-effects and investigate associations between these and subsequent psychological distress.

DESIGN

Longitudinal survey.

SETTING

Two hospital-based colposcopy clinics.

POPULATION

Women with abnormal cytology who underwent colposcopy (±related procedures).

METHODS

Questionnaires were mailed to women 4, 8 and 12 months post-colposcopy. Details of physical after-effects (pain, bleeding and discharge) experienced post-colposcopy were collected at 4 months. Colposcopy-specific distress was measured using the Process Outcome-Specific Measure at all time-points. Linear mixed-effects regression was used to identify associations between physical after-effects and distress over 12 months, adjusting for socio-demographic and clinical variables.

MAIN OUTCOME MEASURES

Prevalence of post-colposcopy physical after-effects. Associations between the presence of any physical after-effects, awareness of after-effects, and number of after-effects and distress.

RESULTS

Five-hundred and eighty-four women were recruited (response rate = 73, 59 and 52% at 4, 8 and 12 months, respectively). Eighty-two percent of women reported one or more physical after-effect(s). Multiple physical after-effects were common (two after-effects = 25%; three after-effects = 25%). Psychological distress scores declined significantly over time. In adjusted analyses, women who experienced all three physical after-effects had on average a 4.58 (95% CI: 1.10-8.05) higher distress scored than those who experienced no after-effects. Women who were unaware of the possibility of experiencing after-effects scored significantly higher for distress during follow-up.

CONCLUSIONS

The prevalence of physical after-effects of colposcopy and related procedures is high. The novel findings of inter-relationships between awareness of the possibility of after-effects and experiencing multiple after-effects, and post-colposcopy distress may be relevant to the development of interventions to alleviate post-colposcopy distress.

TWEETABLE ABSTRACT

Experiencing multiple physical after-effects of colposcopy is associated with psychological distress.

Evolutionarily conserved dual lysine motif determines the non-chaperone function of secreted Hsp90alpha in tumour progression

Both intracellular and extracellular heat shock protein-90 (Hsp90) family proteins (α and β) have been shown to support tumour progression. The tumour-supporting activity of the intracellular Hsp90 is attributed to their N-terminal ATPase-driven chaperone function. What molecular entity determines the extracellular function of secreted Hsp90 and the distinction between Hsp90α and Hsp90β was unclear. Here we demonstrate that CRISPR/Case9 knocking out Hsp90α nullifies tumour cells' ability to migrate, invade and metastasize without affecting the cell survival and growth. Knocking out Hsp90β leads to tumour cell death. Extracellular supplementation with recombinant Hsp90α, but not Hsp90β, protein recovers tumourigenicity of the Hsp90α-knockout cells. Sequential mutagenesis identifies two evolutionarily conserved lysine residues, lys-270 and lys-277, in the Hsp90α subfamily that determine the extracellular Hsp90α function. Hsp90β subfamily lacks the dual lysine motif and the extracellular function. Substitutions of gly-262 and thr-269 in Hsp90β with lysines convert Hsp90β to a Hsp90α-like protein. Newly constructed monoclonal antibody, 1G6-D7, against the dual lysine region of secreted Hsp90α inhibits both de novo tumour formation and expansion of already formed tumours in mice. This study suggests an alternative therapeutic approach to target Hsp90 in cancer, that is, the tumour-secreted Hsp90α, instead of the intracellular Hsp90α and Hsp90β.

Social networks, social support and social negativity: A qualitative study of head and neck cancer caregivers' experiences

Head and neck cancer is a serious form of cancer that can generate substantial physical and psychosocial morbidity. Informal caregivers can help patients to manage head and neck cancer and its emotional impacts, both during and after treatment. Caregivers, however, can experience considerable stress as a result of their caring activities. Supportive relationships can protect caregivers from psychosocial strain. Thirty-one head and neck cancer caregivers were interviewed about their experiences of accessing social support from their social networks; difficulties that they experienced accessing this support; and strategies that they used to address these difficulties. Results suggest that head and neck cancer caregivers strongly value social support, but can find it difficult to obtain, and a number of them experience socially negative responses from their networks. Some carers attempt to answer or supplement support deficiencies by turning to non-human coping supports, such as pets, spiritual figures or medication. Implications for theory and practice are discussed.

Cross-national perspectives about weight-based bullying in youth: nature, extent and remedies

BACKGROUND

No cross-national studies have examined public perceptions about weight-based bullying in youth.

OBJECTIVES

To conduct a multinational examination of public views about (i) the prevalence/seriousness of weight-based bullying in youth; (ii) the role of parents, educators, health providers and government in addressing this problem and (iii) implementing policy actions to reduce weight-based bullying.

METHODS

A cross-sectional survey of adults in the United States, Canada, Iceland and Australia (N = 2866).

RESULTS

Across all countries, weight-based bullying was identified as the most prevalent reason for youth bullying, by a substantial margin over other forms of bullying (race/ethnicity, sexual orientation and religion). Participants viewed parents and teachers as playing major roles in efforts to reduce weight-based bullying. Most participants across countries (77-94%) viewed healthcare providers to be important intervention agents. Participants (65-87%) supported government augmentation of anti-bullying laws to include prohibiting weight-based bullying. Women expressed higher agreement for policy actions than men, with no associations found for participants' race/ethnicity or weight. Causal beliefs about obesity were associated with policy support across countries.

CONCLUSIONS

Across countries, strong recognition exists of weight-based bullying and the need to address it. These findings may inform policy-level actions and clinical practices concerning youth vulnerable to weight-based bullying.

Sensitive method for measuring third order nonlinearities in compact dielectric and hybrid plasmonic waveguides

We demonstrate a sensitive method for the nonlinear optical characterization of micrometer long waveguides, and apply it to typical silicon-on-insulator nanowires and to hybrid plasmonic waveguides. We demonstrate that our method can detect extremely small nonlinear phase shifts, as low as 7.5·10<(-4) rad. The high sensitivity achieved imparts an advantage when investigating the nonlinear behavior of metallic structures as their short propagation distances complicates the task for conventional methods. Our results constitute the first experimental observation of χ((3)) nonlinearities in the hybrid plasmonic platform and is important to test claims of hybrid plasmonic structures as candidates for efficient nonlinear optical devices.

Genomic interaction between ER and HMGB2 identifies DDX18 as a novel driver of endocrine resistance in breast cancer cells

Breast cancer resistance to endocrine therapies such as tamoxifen and aromatase inhibitors is a significant clinical problem. Steroid receptor coactivator-1 (SRC-1), a coregulatory protein of the oestrogen receptor (ER), has previously been shown to have a significant role in the progression of breast cancer. The chromatin protein high mobility group box 2 (HMGB2) was identified as an SRC-1 interacting protein in the endocrine-resistant setting. We investigated the expression of HMGB2 in a cohort of 1068 breast cancer patients and found an association with increased disease-free survival time in patients treated with endocrine therapy. However, it was also verified that HMGB2 expression could be switched on in endocrine-resistant tumours from breast cancer patients. To explore the function of this poorly characterized protein, we performed HMGB2 ChIPseq and found distinct binding patterns between the two contexts. In the resistant setting, the HMGB2, SRC-1 and ER complex are enriched at promoter regions of target genes, with bioinformatic analysis indicating a switch in binding partners between the sensitive and resistant phenotypes. Integration of binding and gene expression data reveals a concise set of target genes of this complex including the RNA helicase DDX18. Modulation of DDX18 directly affects growth of tamoxifen-resistant cells, suggesting that it may be a critical downstream effector of the HMGB2:ER complex. This study defines HMGB2 interactions with the ER complex at specific target genes in the tamoxifen-resistant setting.

Improving operation notes and postoperative care: an audit of current practice

The operation note is the single most important document in surgical practice. Ninety one operation notes were assessed on their adherence to guidelines, as well as their legibility and ability to inform postoperative care; as judged by five different healthcare professionals. Results showed a deficiency in essential information and poor legibility overall. Re-audit of 103 operation notes after intervention showed an improvement in nearly all criteria measured. The results indicate that education about current guidelines and an increase in word processing of operation notes improves quality of documentation, and therefore of postoperative care.

Weyl spin liquids

The fractionalization of quantum numbers in interacting quantum many-body systems is a central motif in condensed-matter physics with prominent examples including the fractionalization of the electron in quantum Hall liquids or the emergence of magnetic monopoles in spin-ice materials. Here, we discuss the fractionalization of magnetic moments in three-dimensional Kitaev models into Majorana fermions (and a Z_{2} gauge field) and their emergent collective behavior. We analytically demonstrate that the Majorana fermions form a Weyl superconductor for the Kitaev model on the recently synthesized hyperhoneycomb structure of β-Li_{2}IrO_{3} when applying a magnetic field. We characterize the topologically protected bulk and surface features of this state, which we dub a Weyl spin liquid, including thermodynamic and transport signatures.

Establishing a population-based patient-reported outcomes study (PROMs) using national cancer registries across two jurisdictions: the Prostate Cancer Treatment, your experience (PiCTure) study

OBJECTIVE

To establish an international patient-reported outcomes (PROMs) study among prostate cancer survivors, up to 18 years postdiagnosis, in two countries with different healthcare systems and ethical frameworks.

DESIGN

A cross-sectional, postal survey of prostate cancer survivors sampled and recruited via two population-based cancer registries. Healthcare professionals (HCPs) evaluated patients for eligibility to participate. Questionnaires contained validated instruments to assess health-related quality of life and psychological well-being, including QLQ-C30, QLQ-PR25, EQ-5D-5L, 21-question Depression, Anxiety and Stress Scale (DASS-21) and the Decisional Regret Scale.

SETTING

Republic of Ireland (RoI) and Northern Ireland (NI).

PRIMARY OUTCOME MEASURES

Registration completeness, predictors of eligibility and response, data missingness, unweighted and weighted PROMs.

RESULTS

Prostate cancer registration was 80% (95% CI 75% to 84%) and 91% (95% CI 89% to 93%) complete 2 years postdiagnosis in NI and RoI, respectively. Of 12,322 survivors sampled from registries, 53% (n=6559) were classified as eligible following HCP screening. In the multivariate analysis, significant predictors of eligibility were: being ≤59 years of age at diagnosis (p<0.001), short-term survivor (<5 years postdiagnosis; p<0.001) and from RoI (p<0.001). 3348 completed the questionnaire, yielding a 54% adjusted response rate. 13% of men or their families called the study freephone with queries for assistance with questionnaire completion or to talk about their experience. Significant predictors of response in multivariate analysis were: being ≤59 years at diagnosis (p<0.001) and from RoI (p=0.016). Mean number of missing questions in validated instruments ranged from 0.12 (SD 0.71; EQ-5D-5L) to 3.72 (SD 6.30; QLQ-PR25). Weighted and unweighted mean EQ-5D-5L, QLQ-C30 and QLQ-PR25 scores were similar, as were the weighted and unweighted prevalences of depression, anxiety and distress.

CONCLUSIONS

It was feasible to perform PROMs studies across jurisdictions, using cancer registries as sampling frames; we amassed one of the largest, international, population-based data set of prostate cancer survivors. We highlight improvements which could inform future PROMs studies, including utilising general practitioners to assess eligibility and providing a freephone service.

A multinational examination of weight bias: predictors of anti-fat attitudes across four countries

BACKGROUND/OBJECTIVES

As rates of obesity have increased throughout much of the world, so too have bias and prejudice toward people with higher body weight (that is, weight bias). Despite considerable evidence of weight bias in the United States, little work has examined its extent and antecedents across different nations. The present study conducted a multinational examination of weight bias in four Western countries with comparable prevalence rates of adult overweight and obesity.

METHODS

Using comprehensive self-report measures with 2866 individuals in Canada, the United States, Iceland and Australia, the authors assessed (1) levels of explicit weight bias (using the Fat Phobia Scale and the Universal Measure of Bias) and multiple sociodemographic predictors (for example, sex, age, race/ethnicity and educational attainment) of weight-biased attitudes and (2) the extent to which weight-related variables, including participants' own body weight, personal experiences with weight bias and causal attributions of obesity, play a role in expressions of weight bias in different countries.

RESULTS

The extent of weight bias was consistent across countries, and in each nation attributions of behavioral causes of obesity predicted stronger weight bias, as did beliefs that obesity is attributable to lack of willpower and personal responsibility. In addition, across all countries the magnitude of weight bias was stronger among men and among individuals without family or friends who had experienced this form of bias.

CONCLUSIONS

These findings offer new insights and important implications regarding sociocultural factors that may fuel weight bias across different cultural contexts, and for targets of stigma-reduction efforts in different countries.

Minimally invasive therapy for fetal sacrococcygeal teratoma: case series and systematic review of the literature

OBJECTIVE

Large solid sacrococcygeal teratomas (SCT) can cause high-output cardiac failure and fetal or neonatal death. The aim of this study was to describe the outcomes of minimally invasive antenatal procedures for the treatment of fetal SCT.

METHODS

A case review was performed of five fetuses with a large SCT treated antenatally using minimally invasive techniques, and a systematic literature review on fetal therapy for solid SCTs was carried out.

RESULTS

Five women were referred between 17 + 5 and 26 + 4 weeks' gestation for a large fetal SCT with evidence of fetal cardiac failure. Vascular flow to the tumors was interrupted by fetoscopic laser ablation (n = 1), radiofrequency ablation (RFA; n = 2) or interstitial laser ablation  ±  vascular coiling (n = 2). There were two intrauterine fetal deaths. The other three cases resulted in preterm labor within 10 days of surgery. One neonate died. Two survived without procedure-related complications but had long-term morbidity related to prematurity. The systematic literature review revealed 16 SCTs treated minimally invasively for (early) hydrops. Including our cases, six of 20 hydropic fetuses survived after minimally invasive therapy (30%). Survival after RFA or interstitial laser ablation was 45% (5/11). Of 12 fetuses treated for SCT without obvious hydrops and for which perinatal survival data were available, eight (67%) survived. Mean gestational age at delivery after minimally invasive therapy was 29.7 ± 4.0 weeks. Survival after open fetal surgery in hydropic fetuses was 6/11 (55%), with a mean gestational age at delivery of 29.8 ± 2.9 weeks.

CONCLUSIONS

Fetal therapy can potentially improve perinatal outcomes for hydropic fetuses with a solid SCT, but is often complicated by intrauterine death and preterm birth.

How often do head and neck cancer patients raise concerns related to intimacy and sexuality in routine follow-up clinics?

Intimacy and sexuality problems are underreported in head and neck cancer patients. The aim of this study was to collate the various prompts available in a routine follow-up clinic through the use of an intimacy screening question and Patient's Concerns Inventory (PCI), and to identify how often these problems were raised by patients and what possible actions took place as a consequence. 177 patients completed the intimacy screening question, PCI and UW-QOLv.4 at follow-up clinics, from October 2008 to January 2011. Case note review identified if intimacy was mentioned in clinic letters and if referral for support was made. On the intimacy screening question, 15 % (26) reported problems of considerable/some concern (24) or selected intimacy/sexuality on the PCI (2). The PCI identified that 9 of the 24 reporting the worst problems wanted the topic discussed in clinic, and clinic letters suggested that 5 of these discussed the issue in clinic with 4 being referred on, 3 to a clinical psychologist and 1 to a clinical nurse specialist. Intimacy problems are underreported in clinic reviews. It is a difficult subject to discuss. It will remain a potential unmet need unless attempts are made to advance the opportunities for patient screening, information leaflets, staff training on how to talk about such sensitive issues and referral for counselling.
