Physical activity in pregnant women with Class III obesity: A qualitative exploration of attitudes and behaviours.

OBJECTIVE: To explore the barriers and facilitators to physical activity and lifestyle interventions in pregnant women with Class III obesity (body mass index >40 kg/m(2)). DESIGN: Qualitative study using in-depth, semi-structure interviews framed by the Theory of Planned Behaviour. Semi-structured, in-depth interviews were conducted using a topic guide. Data analysis was undertaken using a Framework Approach and was informed by the theory of planned behaviour. Recruitment and analysis continued until data saturation was reached. SETTING: Participants were recruited from an antenatal clinic for women with Class III obesity. PARTICIPANTS: Pregnant women (n=13) with Class III obesity. MEASUREMENTS AND OUTCOMES: Three major themes emerged from the data analysis: having a healthy lifestyle awareness, complex barriers to lifestyle changes and having personalised solutions to promote healthy lifestyle. Women were aware of the benefits of physical activity during pregnancy but had complex barriers to engaging with activity. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: future lifestyle interventions for women with Class III in pregnancy should take into account individual, societal and support barriers towards weight management and lifestyle choices in pregnancy. Programs that provide personalised support which are sensitive to the specific physical and psychological needs of women with Class III obesity which focus on the benefits and safety of physical activity for both mother and baby may be more likely to be successful. Further research is needed to explore the feasibility and acceptability of tailored programs.

Suicide with hydrogen sulfide.

This presentation will address the recent rise of suicide deaths resulting from the asphyxiation by hydrogen sulfide (H2S) gas.Hydrogen sulfide poisoning has been an infrequently encountered cause of death in medical examiner practice. Most H2S deaths that have been reported occurred in association with industrial exposure.More recently, H2S has been seen in the commission of suicide, particularly in Japan. Scattered reports of this phenomenon have also appeared in the United States.We have recently observed 2 intentional asphyxial deaths in association with H2S. In both cases, the decedents committed suicide in their automobiles. They generated H2S by combining a sulfide-containing tree spray with toilet bowl cleaner (with an active ingredient of hydrogen chloride acid). Both death scenes prompted hazardous materials team responses because of notes attached to the victims' car windows indicating the presence of toxic gas. Autopsy findings included discoloration of lividity and an accentuation of the gray matter of the brain. Toxicology testing confirmed H2S exposure with the demonstration of high levels of thiosulfate in blood.In summary, suicide with H2S appears to be increasing in the United States.

The outreach worker role in an anticipatory care programme: a valuable resource for linking and supporting.

OBJECTIVES: Keep Well, an anticipatory care programme which commenced in Scotland in 2006, aims to reduce health inequalities through holistic health checks in primary care in deprived communities. A new, non-clinical outreach worker role was created to provide support and signposting to Keep Well patients following their health check. There is currently little evidence regarding how the role is perceived. The aim of this study was to understand how staff and patients view the Keep Well outreach worker role. STUDY DESIGN: A qualitative interview-based study was carried out between July and October 2010. METHODS: One-to-one interviews were conducted with 12 Keep Well staff and four patients. Interviews were transcribed, coded and analysed using a thematic analysis approach. RESULTS: The outreach worker role was viewed positively, particularly in terms of partnership working with practices and local services, and the benefits of support to patients. Referring patients to outreach workers reduced pressure on staff, who were able to spend more time on patients' physical health rather than mental health or lifestyle support. Support from an outreach worker enabled patients to make changes to their life and their health. Concerns were about staff turnover, poor referral rates, set-up of the project and misinterpretation of the role. CONCLUSION: Patients and staff perceive benefits from the outreach worker role in providing motivational support to patients from deprived areas.

How well do strategic environmental assessments in Scotland consider human health?

OBJECTIVES: Strategic environmental assessment (SEA) is a systematic approach to identifying, describing, evaluating and reporting on the environmental - and health - effects of policies, plans and strategies. SEAs have potential to improve population health because they assess 'upstream' health determinants and recommend measures to improve these. The authors studied the range of health issues considered in SEAs in Scotland, and the evidence used in their assessment. STUDY DESIGN: Documentary review of 62 consecutive SEA reports. METHODS: Environmental reports were categorized by sector, and the health-related environmental problems, SEA objectives/criteria, differential impacts, evidence, recommended mitigation and monitoring were identified for each report. RESULTS: Environmental reports identified many health-related issues, and set a wide range of health-related objectives/criteria, but these were inconsistent for SEAs assessing similar plans. Few identified differential impacts or mental health impacts. Mitigation focused on mitigating adverse impacts rather than enhancing positive impacts. It was unclear what health evidence was used to inform the judgements made in scoring the plans against SEA objectives. CONCLUSIONS: Many SEAs in Scotland adopt a wide perspective on health, but most fail to identify differential impacts. Health involvement in scoping of health issues and better use of health evidence may enhance their quality.

Epidemiologic trends and geographic patterns of fatal opioid intoxications in Connecticut, USA: 1997-2007.

BACKGROUND: The leading cause of injury death among adults in Connecticut (CT), USA is drug poisonings. We analyzed the epidemiology and geographic distribution of opioid-involved accidental drug-involved intoxication deaths ("overdoses") in CT over an 11-year period. METHODS: We reviewed data from 1997 to 2007 on all adult accidental/undetermined drug intoxication deaths in CT that were referred to the Office of the Chief Medical Examiner (OCME). Regression analyses were conducted to uncover risk factors for fatal opioid-involved intoxications and to compare heroin- to prescription opioid- and methadone-involved deaths. Death locations were mapped to visualize differences in the geographic patterns of overdose by opioid type. RESULTS: Of the 2900 qualifying deaths, 2231 (77%) involved opioids. Trends over time revealed increases in total opioid-related deaths although heroin-related deaths remained constant. Methadone, oxycodone and fentanyl, the most frequently cited prescription opioids, exhibited significant increases in opioid deaths. Prescription opioid-only deaths were more likely to involve other medications (e.g., benzodiazepines) and to have occurred among residents of a suburban or small town location, compared to heroin-involved or methadone-involved deaths. Heroin-only deaths tended to occur among non-Whites, were more likely to involve alcohol or cocaine and to occur in public locations and large cities. CONCLUSIONS: The epidemiology of fatal opioid overdose in CT exhibits distinct longitudinal, risk factor, and geographic differences by opioid type. Each of these trends has implications for public health and prevention efforts.

Violent death in Connecticut, 2001 to 2004.

We reviewed medical examiner, law enforcement, crime laboratory data, and death certificates on all 1,530 violent deaths (homicide, suicide, undetermined firearm) in Connecticut occurring from 2001-2004. There was an average of 383 deaths (rate = 11.2 deaths per 100,000 persons annually). Overall, males aged 20 to 29 were at the greatest risk of violent death (rate = 30.5/100,000). Of all violent deaths 72% were suicides and 28% were homicides. Firearms were used in 33% of suicides and 58% of homicides. The rate of violent death is lower than most other states in the country. In Connecticut suicide is the leading cause of violent death overall; however, in areas characterized by the highest levels of poverty and lowest levels of education, homicide is the leading cause of violent death.

Fatal inhalational anthrax in a 94-year-old Connecticut woman.

We describe the 11th case of bioterrorism-related inhalational anthrax reported in the United States. The presenting clinical features of this 94-year-old woman were subtle and nondistinctive. The diagnosis was recognized because blood cultures were obtained prior to administration of antibiotics, emphasizing the importance of this diagnostic test in evaluating ill patients who have been exposed to Bacillus anthracis. The patient's clinical course was characterized by progression of respiratory insufficiency, pleural effusions and pulmonary edema, and, ultimately, death. Although her B anthracis bacteremia was rapidly sterilized after initiation of antibiotic therapy, viable B anthracis was present in postmortem mediastinal lymph node specimens. The source of exposure to B anthracis in this patient is not known. Exposure to mail that was cross-contaminated as it passed through postal facilities contaminated with B anthracis spores is one hypothesis under investigation.

Firearm-related fatality surveillance in Hartford County, Connecticut.

OBJECTIVES: To evaluate the feasibility of implementing a firearm fatality surveillance system in Hartford County, Connecticut. METHODS: Medical examiner, police, and crime lab data were collected for firearm deaths occurring in Hartford County during 1997. Data included characteristics of victims, suspects, and firearms. We used standard criteria for evaluating an epidemiological surveillance system. RESULTS: The surveillance system detected 52 firearm-related fatalities; 31 were suicides and 21 were homicides. Handguns accounted for 50% of the suicides and 72% of the homicides. Sensitivity was 96%, specificity was 100%, representativeness adequate, simplicity enhanced by a common case identifier, flexibility constrained by the use of existing data, timeliness varied by data source, and system acceptable to all data sources. Estimated statewide cost is $200 per case, or $52,000 per year. CONCLUSION: Firearm injury surveillance in Hartford County is feasible and expansion to statewide coverage possible. The surveillance yielded considerable data at reasonable costs.

ABH antigen typing in bone tissue.

Results obtained from the ABH grouping of bone tissues by the absorption-elution procedure and by a recently described two-dimensional absorption-inhibition procedure are reported. Neither the elution nor the inhibition procedure alone yielded uniformly correct results. A combination procedure consisting of the use of both absorption-elution and two-dimensional absorption-inhibition is proposed for bone ABH grouping. When elution and inhibition were used in combination, specimens yielding concordant results with both techniques were correctly grouped.

St. Louis encephalitis in Memphis-Shelby County, Tennessee, 1975: epidemiologic aspects of human cases.

An epidemic of St. Louis encephalitis (SLE) occurred in Memphis-Shelby County, Tennessee, in the summer of 1975, as part of an outbreak involving large portions of the Eastern United States. A total of 187 suspected cases were reported, of which 62 were laboratory-confirmed or presumptive SLE. The overall attack rate was 8.1/100,000; rates were higher in lower socioeconomic districts. The case fatality rate was 19.4%. Climatologic data and related factors favoring the occurrence of this outbreak are discussed.

Serosurvey of dogs for Brucella canis infection in Memphis, Tennessee.

Following occurrence of a rare case of human Brucella canis in Memphis, Tennessee, the free roaming and confined dog populations of that community and a similar geographical location were surveyed for B canis positivity to identify the foci of infection and to compare positivity rates. Three hundred and two dogs were sampled. Positivity was found only in free roaming dogs in both communities. It is concluded that presence of B canis positivity in free roaming dogs may pose an additional medical threat to communities, thus providing one more sound reason for controlling strays and confining dogs.
