Are schools drivers of COVID-19 infections-an analysis of outbreaks in Colorado, USA in 2020.

BACKGROUND: The impact of school closures/reopening on transmission of SARS-CoV-2 in the wider community remains contested. METHODS: Outbreak data from Colorado, USA (2020), alongside data on implemented public health measures were analyzed. RESULTS: There were three waves (n = 3169 outbreaks; 61 650 individuals). The first was led by healthcare settings, the second leisure/entertainment and the third workplaces followed by other settings where the trajectory was equally distributed amongst essential workplaces, non-essential workplaces, schools and non-essential healthcare.Non-acute healthcare, essential and non-essential workplace experienced more outbreaks compared to education, entertainment, large-group-living and social gatherings.Schools experienced 11% of identified outbreaks, yet involved just 4% of total cases. Conversely, adult-education outbreaks (2%) had disproportionately more cases (9%). CONCLUSION: Our findings suggest schools were not the key driver of the latest wave in infections. School re-opening coinciding with returning to work may have accounted for the parallel rise in outbreaks in those settings suggesting contact-points outside school being more likely to seed in-school outbreaks than contact points within school as the wave of outbreaks in all other settings occurred either prior to or simultaneously with the schools wave.School re-opening is a priority but requires mitigation measures to do so safely including staggering opening of different settings whilst maintaining low levels of community transmission.

Feasibility and acceptability of introducing routine antenatal contraceptive counselling and provision of contraception after delivery: the APPLES pilot evaluation.

OBJECTIVE: To determine the feasibility and acceptability of routine antenatal contraceptive counselling and contraception provision including long-acting reversible contraception (LARC) postpartum. DESIGN: Health service research evaluation. SETTING: Community antenatal clinics and hospital maternity settings in National Health Service, Scotland UK. POPULATION: Women booked for antenatal care. METHODS: Contraceptive counselling with a community midwife (22 weeks' gestation) and provision of contraception (with facilitated access to LARC methods) prior to discharge from maternity hospital. Evaluation consisted of (i) self administered questionnaire (32-34 weeks) of women's views of antenatal contraceptive counselling, (ii) database review of contraceptive methods provided at discharge, and (iii) focus groups with midwives and obstetricians. MAIN OUTCOME MEASURES: Women's views on antenatal contraceptive counselling. Secondary outcomes included (i) uptake of LARC methods and (ii) barriers and facilitators to providing antenatal counselling and contraception. RESULTS: There were 1369 women in the cohort. Questionnaires were distributed to 1064 women (78%) and completed by 794 (75%). In all, 78% of respondents (n = 621) discussed contraception antenatally with a community midwife and 74% (n = 461) found this helpful. Although 43% of respondents (n = 341) were planning to use LARC, only 9% of the cohort (118 of 1369) received LARC prior to discharge. Community midwives indicated that antenatal contraceptive counselling was now embedded in their role, but hospital staff indicated that workloads impacted upon ability to provide contraception for women. CONCLUSIONS: Antenatal contraceptive counselling, delivered by community midwives, is feasible and highly acceptable to women. However, providing contraception and LARC for women before they are discharged home remains a challenge. TWEETABLE ABSTRACT: Giving contraceptive advice antenatally is feasible and acceptable.

Explaining trends in alcohol-related harms in Scotland, 1991-2011 (I): the role of incomes, effects of socio-economic and political adversity and demographic change.

OBJECTIVE: This paper tests the extent to which differing trends in income, demographic change and the consequences of an earlier period of social, economic and political change might explain differences in the magnitude and trends in alcohol-related mortality between 1991 and 2011 in Scotland compared to England & Wales (E&W). STUDY DESIGN: Comparative time trend analyses and arithmetic modelling. METHODS: Three approaches were utilised to compare Scotland with E&W: 1. We modelled the impact of changes in income on alcohol-related deaths between 1991-2001 and 2001-2011 by applying plausible assumptions of the effect size through an arithmetic model. 2. We used contour plots, graphical exploration of age-period-cohort interactions and calculation of Intrinsic Estimator coefficients to investigate the effect of earlier exposure to social, economic and political adversity on alcohol-related mortality. 3. We recalculated the trends in alcohol-related deaths using the white population only to make a crude approximation of the maximal impact of changes in ethnic diversity. RESULTS: Real incomes increased during the 1990s but declined from around 2004 in the poorest 30% of the population of Great Britain. The decline in incomes for the poorest decile, the proportion of the population in the most deprived decile, and the inequality in alcohol-related deaths, were all greater in Scotland than in E&W. The model predicted less of the observed rise in Scotland (18% of the rise in men and 29% of the rise in women) than that in E&W (where 60% and 68% of the rise in men and women respectively was explained). One-third of the decline observed in alcohol-related mortality in Scottish men between 2001 and 2011 was predicted by the model, and the model was broadly consistent with the observed trends in E&W and amongst women in Scotland. An age-period interaction in alcohol-related mortality was evident for men and women during the 1990s and 2000s who were aged 40-70 years and who experienced rapidly increasing alcohol-related mortality rates. Ethnicity is unlikely to be important in explaining the trends or differences between Scotland and E&W. CONCLUSIONS: The decline in alcohol-related mortality in Scotland since the early 2000s and the differing trend to E&W were partly described by a model predicting the impact of declining incomes. Lagged effects from historical social, economic and political change remain plausible from the available data.

Explaining trends in alcohol-related harms in Scotland 1991-2011 (II): policy, social norms, the alcohol market, clinical changes and a synthesis.

OBJECTIVE: To provide a basis for evaluating post-2007 alcohol policy in Scotland, this paper tests the extent to which pre-2007 policy, the alcohol market, culture or clinical changes might explain differences in the magnitude and trends in alcohol-related mortality outcomes in Scotland compared to England & Wales (E&W). STUDY DESIGN: Rapid literature reviews, descriptive analysis of routine data and narrative synthesis. METHODS: We assessed the impact of pre-2007 Scottish policy and policy in the comparison areas in relation to the literature on effective alcohol policy. Rapid literature reviews were conducted to assess cultural changes and the potential role of substitution effects between alcohol and illicit drugs. The availability of alcohol was assessed by examining the trends in the number of alcohol outlets over time. The impact of clinical changes was assessed in consultation with key informants. The impact of all the identified factors were then summarised and synthesised narratively. RESULTS: The companion paper showed that part of the rise and fall in alcohol-related mortality in Scotland, and part of the differing trend to E&W, were predicted by a model linking income trends and alcohol-related mortality. Lagged effects from historical deindustrialisation and socio-economic changes exposures also remain plausible from the available data. This paper shows that policy differences or changes prior to 2007 are unlikely to have been important in explaining the trends. There is some evidence that aspects of alcohol culture in Scotland may be different (more concentrated and home drinking) but it seems unlikely that this has been an important driver of the trends or the differences with E&W other than through interaction with changing incomes and lagged socio-economic effects. Substitution effects with illicit drugs and clinical changes are unlikely to have substantially changed alcohol-related harms: however, the increase in alcohol availability across the UK is likely to partly explain the rise in alcohol-related mortality during the 1990s. CONCLUSIONS: Future policy should ensure that alcohol affordability and availability, as well as socio-economic inequality, are reduced, in order to maintain downward trends in alcohol-related mortality in Scotland.

Name analysis to classify populations by ethnicity in public health: validation of Onomap in Scotland.

OBJECTIVES: Health inequalities between ethnic minorities and the general population are persistent. Addressing them is hampered by the inability to classify individuals' ethnicity accurately. This is addressed by a new name-based ethnicity classification methodology called 'Onomap'. This paper evaluates the diagnostic accuracy of Onomap in identifying population groups by ethnicity, and discusses applications to public health practice. STUDY DESIGN: Onomap was applied to three independent reference datasets (birth registration, pupil census and register of Polish health professionals) collected in Britain and Poland at individual level (n = 260,748). METHODS: Results were compared with the reference database ethnicity 'gold standard'. Outcome measures included sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Ninety-five percent confidence intervals and Chi-squared tests were used. RESULTS: Onomap identified the majority of those in the British participant group with high sensitivity and PPV (>95%), and low misclassification (<5%), although specificity and NPV were lowest in this group (56-87%). Outcome measures for all other non-British groupings were high for specificity and NPV (>98%), but variable for sensitivity and PPV (17-89%). Differences in misclassification by gender were statistically significant. Using maiden name rather than married name in women improved classification outcomes for those born in the British Isles (0.53%, 95% confidence interval 0.26-0.8%; P < 0.001) but not for South Asian or Polish groups. CONCLUSIONS: Onomap offers an effective methodology for identifying population groups in both health-related and educational datasets, categorizing populations into a variety of ethnic groups. This evaluation suggests that it can successfully assist health researchers, planners and policy makers in identifying and addressing health inequalities.

The effect of a large Legionnaires' disease outbreak in Southwest Edinburgh on acute and critical care services.

OBJECTIVE: The largest outbreak of Legionnaires Disease (LD) in the UK for a decade occurred in Edinburgh in June 2012. We describe the clinical and public health management of the outbreak. SETTING: Three acute hospitals covering an urban area of ~480,000. METHODS: Data were collected on confirmed and suspected cases and minutes of the Incident Management Team meetings were reviewed to identify key actions. RESULTS: Over 1600 urine samples and over 600 sputum samples were tested during the outbreak. 61 patients with pneumonia tested positive for Legionella pneumophila serogroup 1 by urinary antigen detection, culture, respiratory PCR or serology. A further 23 patients with pneumonia were treated as suspected cases on clinical and epidemiological grounds but had no microbiological diagnosis. 36% of confirmed and probable cases required critical care admission. Mean ICU length of stay was 11.3 (±7.6) days and mean hospital length of stay for those who were admitted to ICU was 23.0 (±17.2) days. For all hospitalized patients the mean length of stay was 15.7 (±14) days. In total there were four deaths associated with this outbreak giving an overall case fatality of 6.5%. Hospital and critical care mortality was 6.1% and 9.1%, respectively. CONCLUSION: A significant proportion of patients required prolonged multiple organ support or complex ventilation. Case fatality compared favourably to other recent outbreaks in Europe. Access to rapid diagnostic tests and prompt antibiotic therapy may have mitigated the impact of pre-existing poor health among those affected.

A novel estrogen-free oral contraceptive pill for women: multicentre, double-blind, randomized controlled trial of mifepristone and progestogen-only pill (levonorgestrel).

BACKGROUND: The acceptability and continuation rate of oral contraceptive steroids are limited by unpredictable bleeding and the fear of long-term risks such as breast cancer. By inhibiting ovulation and by altering the receptivity of the endometrium, antagonists of progesterone, such as mifepristone, could be developed as estrogen-free novel contraceptives. METHODS: Multicentre, double-blind, randomized controlled trial comparing frequency of amenorrhoea (primary outcome), bleeding patterns, side effects and efficacy in women taking daily 5 mg mifepristone (n = 73) or 0.03 mg levonorgestrel (progestogen-only pill; POP, n = 23) for 24 weeks. RESULTS: More women were amenorrhoeic while taking mifepristone than POP (49 versus 0% P < 0.001), and fewer women bled or spotted for >5 days per month (4 versus 39% P < 0.001). Forty-eight percent of women who took mifepristone for 6 months had cystic glandular dilatation of the endometrium but none showed hyperplasia or atypia. There were no pregnancies in 356 months of exposure in women who used only mifepristone for contraception. Two pregnancies occurred in women taking mifepristone who were also using condoms for dual protection. CONCLUSIONS: Daily mifepristone (5 mg) is an effective oral contraceptive pill which has a better pattern of menstrual bleeding than an existing POP (levonorgestrel).
