ABSTRACT

OBJECTIVES: The criteria for the reimbursement of fluoroquinolones changed in Belgium on 1 May 2018. This study aims to quantify the difference in fluoroquinolone use after this change, and to assess the timing and persistence of this effect, both in terms of total reimbursed fluoroquinolone use and its relative proportion.

METHODS: Longitudinal reimbursement data on fluoroquinolone use in the Belgian community from January 2017 to November 2018 were analysed to identify a change in reimbursed fluoroquinolone use expressed in DDD per 1000 inhabitants per day (DID), using a set of non-linear mixed models including change-points. In addition, longitudinal data on the relative proportion of prescribed fluoroquinolones from January 2017 to December 2018 were analysed to identify a change in the relative proportion of prescribed fluoroquinolones using generalized estimation equations including change-points.

RESULTS: Fluoroquinolone use dropped significantly immediately after the change in reimbursement criteria, from 2.21 DID (95% CI: 2.03-2.38) to 0.52 DID (95% CI: 0.48-0.56) and from 9.14% (95% CI: 8.75%-9.56%) to 6.52% (95% CI: 6.04%-7.04%). The observed decrease in fluoroquinolone use persisted over time.

CONCLUSIONS: While fluoroquinolone use was still above the target of 5% after the change in reimbursement criteria, its implementation helped to lower fluoroquinolone use in Belgium.

ABSTRACT

OBJECTIVES: To determine reproducible MRI parameters predictive of molecular subtype and risk stratification in glioma and develop a structured reporting system.

METHODS: All study patients were initially diagnosed with glioma, 141 from the Cancer Genome Atlas and 131 from our tertiary institution, as training and validation sets, respectively. Images were analyzed by three neuroradiologists with 1-7 years of experience. MRI features including contrast enhancement pattern, necrosis, margin, edema, T2/FLAIR mismatch, internal cyst, and cerebral blood volume higher than normal cortex were reported using a structured reporting system. The pathology was stratified into five risk types: (1) oligodendroglioma, isocitrate dehydrogenase [IDH]-mutant, 1p19q co-deleted; (2) diffuse astrocytoma, IDH-mutant, grade II-III; (3) glioblastoma, IDH-mutant, grade IV; (4) diffuse astrocytoma, IDH-wild, grade II-III; and (5) glioblastoma, IDH-wild, grade IV. Significant predictors were selected using multivariate logistic regression, and diagnostic performance was tested using a validation set.

RESULTS: Reproducible imaging parameters exhibiting > 50% agreement across readers included the presence of necrosis, T2/FLAIR mismatch, internal cyst, and predominant contrast enhancement. In the validation set, prediction of risk type 5 exhibited the highest diagnostic performance with AUCs of 0.92 (reader 1) and 0.93 (reader 2) with predominant enhancement, followed by risk type 2 with AUCs of 0.95 and 0.95 with T2/FLAIR mismatch sign and no necrosis, and risk type 1 with AUCs of 0.84 and 0.83 with internal cyst or necrosis. Risk types 3 and 4 were difficult to visually predict.

CONCLUSIONS: Imaging parameters with high reproducibility enabling prediction of IDH-wild-type glioblastoma, IDH-mutant/1p19q co-deletion oligodendroglioma, and IDH-mutant diffuse astrocytoma were identified.

KEY POINTS: • Reproducible MRI parameters for determining molecular subtypes of glioma included the presence of necrosis, T2/FLAIR mismatch, internal cyst, and predominant contrast enhancement. • IDH-wild type glioblastoma, IDH-mutant/1p19q co-deletion oligodendroglioma, and IDH-mutant low-grade astrocytoma were identified using MRI parameters with high inter-reader reproducibility. • Identification of IDH-wild type low-grade glioma and IDH-mutant glioblastoma was difficult by visual analysis.

ABSTRACT

Objectives We investigated the participation and detection rates of cervical lesions in cervical screening non-attenders offered HPV (human papillomavirus) self-sampling with cytology triage.Methods From 2016 to 2018, HPV self-sampling was routinely offered as an option, along with cytology, to all non-attenders in Ebetsu City, Japan. The primary endpoints were ≥CIN2 and ≥CIN3 detection rates, and secondary endpoints were abnormal cytology rates and follow-up compliance.Results Overall, recall invitations were mailed to 6,116 non-attenders, with a response rate of 15.9% (cytology: 6.5%, HPV testing: 9.4%). Of the responders to undergo HPV self-sampling, 11.7% had a positive result and were referred to cytology triage. Moreover, ≥CIN2 and ≥CIN3 detection rates were 1.7% and 0.9%, respectively, in the HPV self-sampling group, and 1.0% and 0.8%, respectively, in the cytology group, showing no statistically significant differences. In those who underwent cytology triage following an HPV positive test, ≥CIN2 and ≥CIN3 detection rates were 23.8% and 11.9%, respectively, which was significantly higher than those who only underwent cytology alone.Conclusion HPV self-sampling followed by cytology triage is highly effective at detecting high grade disease in non-attenders. Thus, multi-municipality-based studies to standardize processes involving this method are warranted. Furthermore, HPV self-sampling could be a promising method for inviting non-attenders who have difficulty undergoing cervical screening in the COVID-19 pandemic era.

ABSTRACT

Objectives The proportion of Japanese women who maintain their employment during pregnancy and after delivery has been increasing. Previous studies from Western countries showed an association between the mother’s occupation and birth outcomes; however, to the best of our knowledge, no epidemiological study has analyzed this association in Japan. Therefore, data from the national Vital Statistics: Occupational and Industrial Aspects were used to examine the association between the mother’s occupation and (1) the risk of stillbirth at or after 12 weeks of gestation, and (2) the risk of infant death under 1 year of age after livebirth.Methods Data from the Vital Statistics: Occupational and Industrial Aspects (Live Birth Form, and Foetal Death Form) for fiscal years (FYs) 1995, 2000, 2005, 2010, and 2015 and Vital Statistics data files (Death Form) from FYs 1995-96, 2000-01, 2005-06, 2010-11, and 2015-16 were analyzed. The study population consisted of (1) 5,355,881 infants who were born during the survey period, with (2) 5,290,808 live birth excluding still birth during the same period. The odds ratios (ORs) were estimated for (1) stillbirth (without stillbirth = livebirth) and (2) infant death (without infant death = alive at 1 year of age) by mother’s occupation (managers/specialist/technical workers, clerical workers, sales workers, service workers, blue collar workers, and not employed) using logistic regression. Blue collar workers included workers in security, agriculture/forestry/fishing, manufacturing process, transport, and machine operation. The population attributable risk (PAR) for stillbirth attributed to mother’s occupation among employed mothers was also calculated.Results There were 61,179 (1.1%) stillbirths in the study population and 12,789 (0.2%) infant deaths among 5,290,808 live birth. Compared to managers/specialist/technical workers, the adjusted ORs (95% confidence interval) for stillbirth among clerical workers, sales workers, service workers, blue collar workers and not employed women were 1.24 (1.20-1.29), 1.48 (1.41-1.56), 1.76 (1.69-1.83), 1.54 (1.46-1.61), and 0.95 (0.92-0.98), respectively. There was no association between the mother’s occupation and infant deaths. The PAR values for stillbirth among mothers employed as clerical workers and service workers were 7.4% and 12.3%.Conclusion The risk of stillbirth differed according to the mother’s occupation in our study. The OR and PAR of stillbirth were the highest for service workers. Mother’s occupation was not associated with the risk of infant death; therefore, the mothers’ occupation is likely to affect the children’s condition only during pregnancy. Our study suggests the importance of understanding the causal linkage between pregnant women’s occupation and birth outcomes.

ABSTRACT

OBJECTIVES: To investigate the combined association of obesity, diabetes mellitus (DM) and cardiovascular disease (CVD) with severe COVID-19 outcomes in adult and elderly inpatients.

DESIGN: Cross-sectional study based on registry data from Brazil’s influenza surveillance system.

SETTING: Public and private hospitals across Brazil.

PARTICIPANTS: Eligible population included 21 942 inpatients aged ≥20 years with positive reverse transcription-PCR test for SARS-CoV-2 until 9 June 2020.

MAIN OUTCOME MEASURES: Severe COVID-19 outcomes were non-invasive and invasive mechanical ventilation use, intensive care unit (ICU) admission and death. Multivariate analyses were conducted separately for adults (20-59 years) and elders (≥60 years) to test the combined association of obesity (without and with DM and/or CVD) and degrees of obesity with each outcome.

RESULTS: A sample of 8848 adults and 12 925 elders were included. Among adults, obesity with DM and/or CVD showed higher prevalence of invasive (prevalence ratio 3.76, 95% CI 2.82 to 5.01) and non-invasive mechanical ventilation use (2.06, 1.58 to 2.69), ICU admission (1.60, 1.40 to 1.83) and death (1.79, 1.45 to 2.21) compared with the group without obesity, DM and CVD. In elders, obesity alone (without DM and CVD) had the highest prevalence of ICU admission (1.40, 1.07 to 1.82) and death (1.67, 1.00 to 2.80). In both age groups, obesity alone and combined with DM and/or CVD showed higher prevalence in all outcomes than DM and/or CVD. A dose-response association was observed between obesity and death in adults: class I 1.32 (1.05 to 1.66), class II 1.41 (1.06 to 1.87) and class III 1.77 (1.35 to 2.33).

CONCLUSIONS: The combined association of obesity, diabetes and/or CVD with severe COVID-19 outcomes may be stronger in adults than in elders. Obesity alone and combined with DM and/or CVD had more impact on the risk of COVID-19 severity than DM and/or CVD in both age groups. The study also supports an independent relationship of obesity with severe outcomes, including a dose-response association between degrees of obesity and death in adults.

ABSTRACT

OBJECTIVES: The arts therapies include music therapy, dance movement therapy, art therapy and dramatherapy. Preferences for art forms may play an important role in engagement with treatment. This survey was an initial exploration of who is interested in group arts therapies, what they would choose and why.

DESIGN: An online cross-sectional survey of demographics, interest in and preferences for the arts therapies was designed in collaboration with patients. The survey took 10 min to complete, including informed consent and 14 main questions. Summary statistics, multinomial logistic regression and thematic analysis were used to analyse the data.

SETTING: Thirteen National Health Service mental health trusts in the UK asked mental health patients and members of the general population to participate.

PARTICIPANTS: A total of 1541 participants completed the survey; 685 mental health patients and 856 members of the general population. All participants were over 18 years old, had capacity to give informed consent and sufficient understanding of English. Mental health patients had to be using secondary mental health services.

RESULTS: Approximately 60% of participants would be interested in taking part in group arts therapies. Music therapy was the most frequent choice among mental health patients (41%) and art therapy was the most frequent choice in the general population (43%). Past experience of arts therapies was the most important predictor of preference for that same modality. Expectations of enjoyment, helpfulness, feeling capable, impact on mood and social interaction were most often reported as reasons for preferring one form of arts therapy.

CONCLUSIONS: Large proportions of the participants expressed an interest in group arts therapies. This may justify the wide provision of arts therapies and the offer of more than one modality to interested patients. It also highlights key considerations for assessment of preferences in the arts therapies as part of shared decision-making.

ABSTRACT

Carnivorous plants consume animals for mineral nutrients that enhance growth and reproduction in nutrient-poor environments. Here, we report that Triantha occidentalis (Tofieldiaceae) represents a previously overlooked carnivorous lineage that captures insects on sticky inflorescences. Field experiments, isotopic data, and mixing models demonstrate significant N transfer from prey to Triantha, with an estimated 64% of leaf N obtained from prey capture in previous years, comparable to levels inferred for the cooccurring round-leaved sundew, a recognized carnivore. N obtained via carnivory is exported from the inflorescence and developing fruits and may ultimately be transferred to next year’s leaves. Glandular hairs on flowering stems secrete phosphatase, as seen in all carnivorous plants that directly digest prey. Triantha is unique among carnivorous plants in capturing prey solely with sticky traps adjacent to its flowers, contrary to theory. However, its glandular hairs capture only small insects, unlike the large bees and butterflies that act as pollinators, which may minimize the conflict between carnivory and pollination.

ABSTRACT

INTRODUCTION: India is home to 20% of the world’s children and yet, little is known on the magnitude and trends of child maltreatment nationwide. The aims of this review are to provide a prevalence of child maltreatment in India with considerations for any effects of gender; urbanisation (eg, urban vs rural) and legislation (Protection of Children from Sexual Offences (POCSO) Act 2012).

METHODS AND ANALYSIS: A rapid review will be undertaken of all quantitative peer-reviewed studies on child maltreatment in India between 2005 and 2020. Four electronic databases will be systematically searched: PubMed, EMBASE, Cochrane and PsychInfo. The primary outcomes will include all aspects of child maltreatment: physical abuse, sexual abuse, emotional abuse, emotional neglect and physical neglect. Study participants will be between 0 and 18 years and will have reported maltreatment experiences using validated, reliable tools such as the Adverse Childhood Experiences Questionnaire as well as child self-reports and clinician reports. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the methodological appraisal of the studies will be assessed by the Newcastle-Ottawa Quality assessment scale. A narrative synthesis will be conducted for all included studies. Also, if sufficient data are available, a meta-analysis will be conducted. Effect sizes will be determined from random-effects models stratified by gender, urbanisation and the pre-2012 and post-2012 POCSO Act cut-off. I² statistics will be used to assess heterogeneity and identify their potential sources and τ² statistics will indicate any between-study variance.

ETHICS AND DISSEMINATION: As this is a rapid review, minimal ethical risks are expected. The protocol and level 1 self-audit checklist were submitted and approved by the Usher Research Ethics Group panel in the Usher Institute (School of Medicine and Veterinary Sciences) at the University of Edinburgh (Reference B126255). Findings from this review will be disseminated widely through peer-reviewed publications and in various media, for example, conferences, congresses or symposia.

ABSTRACT

BACKGROUND: Patient and public involvement (PPI) in research is well-established in the UK. However, it can be challenging to introduce PPI to research communities where there is limited prior knowledge, experience or appreciation of PPI. We aimed to explore current PPI practices, experiences and ethical and operational challenges with PPI within our own research community in Austria, to inform strategies for supporting PPI in Austria going forward.

METHODS: We surveyed scientists at 21 research institutes of the Ludwig Boltzmann Gesellschaft (LBG) and representatives of 32 medical and university research ethics committees in Austria using online questionnaires. We analysed quantitative data using descriptive statistics, and we collated textual responses to open questions. We combined survey data with anecdotal evidence from our personal experience to summarise current challenges around implementing PPI in Austria.

RESULTS: Nineteen scientists from nine research institutes indicated generally positive attitudes towards PPI. However, the majority reported they rarely or never involved patients and members of the public in roles of consultation, collaboration or control in research. Six of eight ethics committees were unfamiliar with PPI. We discern five current challenges to implementing PPI in Austria: lack of knowledge and skills for PPI among scientists, scepticism about the usefulness of PPI, conflation of PPI with qualitative research, uncertainty about ethical requirements for PPI and uncertainty about publishing PPI activities.

DISCUSSION: We suggest that the provision of guidance about ethical requirements of PPI is a strategic priority. To address this, and following on from a recently introduced PPI training and grant scheme by the LBG, our surveys have initiated a dialogue with ethics committees and have informed the development of a checklist for ethical aspects of PPI.

CONCLUSION: Our experiences may provide useful examples to others who seek to introduce or strengthen PPI practices within their own research communities.

ABSTRACT

BACKGROUND: No validated English language patient-reported outcome (PRO) currently exists that assesses satisfaction with inflatable penile prosthesis (IPP). Satisfaction data have been largely based primarily on surgeon assessment of patients or using questionnaires that have not been designed for this purpose.

AIM: To develop an English-language validated PRO that assesses patient satisfaction after IPP surgery.

METHODS: Initially, a literature review and discussions with experts defined domains important to IPP satisfaction (pain, appearance, function, overall satisfaction). The initial 35-item Satisfaction Survey for Inflatable Penile Implant (SSIPI) was developed. Cognitive interviews were then performed with IPP patients (n = 12) to gain feedback on the SSIPI domains and items. These data were used to modify SSIPI with the addition of 2 questions for a final item number of 37. Patients from 4 centers, who were between 6 months and 5 years after IPP, were administered the questionnaire through RedCap. Reliability statistics and content analysis were used to winnow questions to yield the final 16-item version of the SSIPI. Internal consistency was assessed via Cronbach’s alpha and item-total correlation. Test-retest reliability was assessed via intraclass correlation coefficients using baseline and 2-week data. For convergent validity, the Erectile Dysfunction Inventory of Treatment Satisfaction and the Self-Esteem and Relationship (SEAR) questionnaire were used. For discriminant validity, the International Prostate Symptom Score (IPSS) was used. Confirmatory factor analysis was used to assess the factor structure of the SSIPI.

OUTCOMES: Internal consistency, test-retest reliability, convergent and discriminant validity, and confirmatory factor analysis were assessed.

RESULTS: 118 men were surveyed. Mean age was 66.8 ± 9.5 years. The 16-item SSIPI showed high internal consistency with an overall Cronbach’s Alpha of 0.97 (domains 0.85-0.89). Item-total correlations for individual items to subscales ranged from 0.60 to 0.91. The overall test-retest reliability was 0.94 (domains 0.87-0.93). Erectile Dysfunction Inventory of Treatment Satisfaction and Self-Esteem and Relationship had correlations of 0.84 overall (domains 0.57-0.79) and 0.47 overall (domains 0.34-0.44), respectively. International Prostate Symptom Score (discriminant validity) had correlations of -0.29 overall (domains -0.17 to -0.31).

CLINICAL IMPLICATIONS: SSIPI is the first English-language validated IPP satisfaction PRO. This will enable clinicians to collect satisfaction data in a standardized way.

STRENGTHS AND LIMITATIONS: As strengths we have used a rigorous psychometric process and have no industry sponsorship. Limitations include small numbers of specific subpopulations.

CONCLUSION: The SSIPI has demonstrated robust psychometric properties. Salter CA, Bach PV, Jenkins L, et al. Development and Validation of the Satisfaction Survey for Inflatable Penile Implant (SSIPI). J Sex Med 2021;XX:XXX-XXX.
