Improving smoking cessation care in pregnancy at Aboriginal Medical Services: 'ICAN QUIT in Pregnancy' step-wedge cluster randomised study
Objectives This study aimed to examine the impact of the
‘ICAN QUIT in Pregnancy’ intervention on individual health
providers (HPs) smoking cessation care (SCC) knowledge,
attitudes and practices in general, and specifically
regarding nicotine replacement therapy (NRT) prescription.
Design Step-wedge clustered randomised controlled
study. HPs answered a preintervention and 1–6 months
postintervention survey.
Setting Six Aboriginal Medical Services (AMSs) in three
states of Australia.
Participants All HPs were invited to participate. Of 93
eligible, 50 consented (54%), 45 completed the presurvey
(90%) and 20 the post (40%).
Intervention Included three 1-hour webinar sessions,
educational resource package and free oral NRT.
Outcomes HPs knowledge was measured using
two composite scores—one from all 24 true/false
statements, and one from 12 NRT-specific statements.
Self-assessment of 22 attitudes to providing SCC were
measured using a five-point Likert scale (Strongly disagree
to Strongly agree). Two composite mean scores were
calculated—one for 15 general SCC attitudes, and one for
7 NRT-specific attitudes. Self-reported provision of SCC
components was measured on a five-point Likert scale
(Never to Always). Feasibility outcomes, and data collected
on the service and patient level are reported elsewhere.
Results Mean knowledge composite scores improved
from pre to post (78% vs 84% correct, difference 5.95,
95%CI 1.57 to 10.32). Mean NRT-specific knowledge
composite score also improved (68% vs 79% correct,
difference 9.9, 95%CI 3.66 to 16.14). Mean attitude
composite score improved (3.65 (SD 0.4) to 3.87 (SD 0.4),
difference 0.23, 95%CI 0.05 to 0.41). Mean NRT-specific
attitudes composite score also improved (3.37 (SD 0.6) to
3.64 (SD 0.7), difference 0.36, 95%CI 0.13 to 0.6). Selfreported practices were unchanged, including prescribing
NRT.
Conclusions A multicomponent culturally sensitive
intervention in AMSs was feasible, and might improve HPs
provision of SCC to pregnant Aboriginal women. Changes
in NRT prescription rates may require additional intensive
measures
Incidence of Schizophrenia and Other Psychoses in England, 1950–2009: A Systematic Review and Meta-Analyses
Background
We conducted a systematic review of incidence rates in England over a sixty-year period to determine the extent to which rates varied along accepted (age, sex) and less-accepted epidemiological gradients (ethnicity, migration and place of birth and upbringing, time).
Objectives
To determine variation in incidence of several psychotic disorders as above.
Data Sources
Published and grey literature searches (MEDLINE, PSycINFO, EMBASE, CINAHL, ASSIA, HMIC), and identification of unpublished data through bibliographic searches and author communication.
Study Eligibility Criteria
Published 1950–2009; conducted wholly or partially in England; original data on incidence of non-organic adult-onset psychosis or one or more factor(s) pertaining to incidence.
Participants
People, 16–64 years, with first -onset psychosis, including non-affective psychoses, schizophrenia, bipolar disorder, psychotic depression and substance-induced psychosis.
Study Appraisal and Synthesis Methods
Title, abstract and full-text review by two independent raters to identify suitable citations. Data were extracted to a standardized extraction form. Descriptive appraisals of variation in rates, including tables and forest plots, and where suitable, random-effects meta-analyses and meta-regressions to test specific hypotheses; rate heterogeneity was assessed by the I2-statistic.
Results
83 citations met inclusion. Pooled incidence of all psychoses (N = 9) was 31.7 per 100,000 person-years (95%CI: 24.6–40.9), 23.2 (95%CI: 18.3–29.5) for non-affective psychoses (N = 8), 15.2 (95%CI: 11.9–19.5) for schizophrenia (N = 15) and 12.4 (95%CI: 9.0–17.1) for affective psychoses (N = 7). This masked rate heterogeneity (I2: 0.54–0.97), possibly explained by socio-environmental factors; our review confirmed (via meta-regression) the typical age-sex interaction in psychosis risk, including secondary peak onset in women after 45 years. Rates of most disorders were elevated in several ethnic minority groups compared with the white (British) population. For example, for schizophrenia: black Caribbean (pooled RR: 5.6; 95%CI: 3.4–9.2; N = 5), black African (pooled RR: 4.7; 95%CI: 3.3–6.8; N = 5) and South Asian groups in England (pooled RR: 2.4; 95%CI: 1.3–4.5; N = 3). We found no evidence to support an overall change in the incidence of psychotic disorder over time, though diagnostic shifts (away from schizophrenia) were reported.
Limitations
Incidence studies were predominantly cross-sectional, limiting causal inference. Heterogeneity, while evidencing important variation, suggested pooled estimates require interpretation alongside our descriptive systematic results.
Conclusions and Implications of Key Findings
Incidence of psychotic disorders varied markedly by age, sex, place and migration status/ethnicity. Stable incidence over time, together with a robust socio-environmental epidemiology, provides a platform for developing prediction models for health service planning
Improving smoking cessation care in pregnancy at Aboriginal Medical Services: 'ICAN QUIT in Pregnancy' step-wedge cluster randomised study
Planning is critical to mitigating the sudden and potentially catastrophic impact of an infectious disease pandemic on society. National pandemic policy documents cover a wide variety of control options, often with nonspecific recommendations for action. Despite advances in analytical methods for gaining early situational awareness (i.e., of a disease’s transmissibility and severity) and for predicting the likely effectiveness of interventions, a major gap exists globally in terms of integrating these outputs with the advice contained in policy documents. Decision models (and decision science as a field, more broadly) provide an approach to
defining and evaluating alternative policy options under complex and changing conditions. A decision model for infectious disease pandemics is an appropriate method for integrating evidence from situational and intervention analysis tools, along with the information in policy documents, to provide robust advice on possible response options (including uncertainty). A decision model for pandemic response cannot capture all of the social, political, and ethical considerations that impact decision-making. Such a model should therefore be embedded in a decision support system that emphasizes this broader context.Freya M. Shearer, Robert Moss, Jodie McVernon, Joshua V. Ross, James

Ethnic inequalities in the incidence of diagnosis of severe mental illness in England: a systematic review and new meta-analyses for non-affective and affective psychoses.
This is a post-peer-review, pre-copyedit version of an article published in Social Psychiatry and Psychiatric Epidemiology. The final authenticated version is available online at: https://doi.org/10.1007/s00127-019-01758-yPURPOSE: Although excess risks particularly for a diagnosis of schizophrenia have been identified for ethnic minority people in England and other contexts, we sought to identify and synthesise up-to-date evidence (2018) for affective in addition to non-affective psychoses by specific ethnic groups in England. METHODS: Systematic review and meta-analysis of ethnic differences in diagnosed incidence of psychoses in England, searching nine databases for reviews (citing relevant studies up to 2009) and an updated search in three databases for studies between 2010 and 2018. Studies from both searches were combined in meta-analyses allowing coverage of more specific ethnic groups than previously. RESULTS: We included 28 primary studies. Relative to the majority population, significantly higher risks of diagnosed schizophrenia were found in Black African (Relative risk, RR 5.72, 95% CI 3.87-8.46, n = 9); Black Caribbean (RR 5.20, 95% CI 4.33-6.24, n = 21); South Asian (RR 2.27, 95% CI 1.63-3.16, n = 14); White Other (RR 2.24, 95% CI 1.59-3.14, n = 9); and Mixed Ethnicity people (RR 2.24, 95% CI 1.32-3.80, n = 4). Significantly higher risks for diagnosed affective psychoses were also revealed: Black African (RR 4.07, 95% CI 2.27-7.28, n = 5); Black Caribbean (RR 2.91, 95% CI 1.78-4.74, n = 16); South Asian (RR 1.71, 95% CI 1.07-2.72, n = 8); White Other (RR 1.55, 95% CI 1.32-1.83, n = 5); Mixed Ethnicity (RR 6.16, 95% CI 3.99-9.52, n = 4). CONCLUSIONS: The risk for a diagnosis of non-affective and affective psychoses is particularly elevated for Black ethnic groups, but is higher for all ethnic minority groups including those previously not assessed through meta-analyses (White Other, Mixed Ethnicity). This calls for further research on broader disadvantages affecting ethnic minority people.Lankelly Chase Foundatio
The enantioselective synthesis of a[alpha],a[alpha],́b[beta],b[beta]-́tetrafluoroethylidene substituted carbohydrates
The syntheses of a number of tetrafluoroethylidene substituted carbohydrates are disclosed. From a commercially available fluorinated building block chirality is introduced by way of an asymmetric dihydroxylation (AD). We also disclose the beginnings of work towards the synthesis of fluorinated chiral ligands designed for use in this AD. The chiral 1,2-diol obtained from the AD is selectively protected at either the primary or secondary alcohol to form the central intermediate our our syntheses. The functionalisation and subsequent cyclisation of these compounds are disclosed. To synthesise compounds with the tetrafluoroethylidene unit proximal to the anomeric centre we utilised a novel halogen-lithium exchange/cyclisation procedure. This reaction is shown to have wide scope being used to synthesise hexoses and pentoses in both their pyranose and hexose forms. The intermediate is also shown to take part in a radical addition/atom transfer/nucleophilic cyclisation sequence to form tetrafluoroethylidene substituted carbohydrates where the fluorinated substituent is remote from the anomeric centre. We also disclose the synthesis of a tetrafluoroethylidene substituted nucleoside and glycal.</p
Efficient desymmetrization of "Pseudo"-C-2-symmetric substrates: illustration in the synthesis of a disubstituted butenolide from arabitol
A short synthesis of the homochiral disubstituted butenolide 1 is described in four steps from arabitol. The key steps are the selective kinetic protection of arabitol and the cyclization of 11 to form the butenolide ring. This last transformation represents a rare example of a fully stereoselective cyclitive desymmetrization process of a "pseudo"-C-2-symmetric substrate
A stereoselective cyclization to carbafuranose derivatives starting from 1,4-bis-epoxides
A concise synthesis of highly functionalized cyclopentane derivatives via a Brook rearrangement mediated stereoselective linchpin cyclization reaction involving tert-butyldimethylsilyl-1,3-dithianyllithium and homochiral 1,4-bis-epoxides is described
A qualitative examination of affect and ideology within mass media interventions to increase HIV testing with gay men garnered from a systematic review
Objectives: Increasing appropriate HIV testing among men who have sex with men (MSM) is crucial to HIV prevention. Mass media interventions are effective in promoting testing, but to date there has been little examination of their active content.
Design: We conducted a qualitative analysis of intervention materials (n=69) derived from a systematic review of mass media interventions designed to improve testing with MSM.
Methods: Visual data were analysed for their affective and ideological content using a novel method drawing on concepts from semiotics (i.e., broadly speaking, the analysis of signs).
Results: Whilst affect was not explicitly theorized or examined in any of the studies, there are clearly identifiable affective elements implicitly at play in these interventions. Four thematic categories of affect/ideology were identified including: (1) sexual desire and the ‘pornographication’ of the gay/bisexual male subject; (2) narratives of romance and love; (3) fear, threat and regret; (4) ‘flattened’ affect.
Conclusions: This is the first study to examine and detail the affective and ideological aspects of intervention content in this field. Using analytic techniques such as those reported here, in addition to approaches that focus on the manner in which intervention content address more proximal determinants of behaviour, can provide a rich and potentially more useful evidence-base to assist with future interventions
