Social Support and Smoking Abstinence among Incarcerated Adults in the United States: A Longitudinal Study
Background:
In the United States, tobacco use among prisoners is nearly three times that of the general population. While many American prisons and jails are now tobacco-free, nearly all inmates return to smoking as soon as they are released back into the community.
Methods:
To better understand the role that personal relationships may play in enabling return to smoking, we enrolled former-smokers who were inmates in a tobacco-free prison. Baseline assessments were conducted six weeks prior to inmates’ scheduled release and included measures of smoking prior to incarceration, motivation, confidence and plans for remaining quit after release. We also assessed global social support (ISEL) and a measure of social support specific to quitting smoking (SSQ). Smoking status was assessed three weeks after prison release and included 7-day point-prevalence abstinence validated by urine cotinine, days to first cigarette and smoking rate.
Results:
A diverse sample comprised of 35% women, 20% Hispanic, and 29% racial minorities (average age 35.5 years) provided baseline data (n = 247). Over 90% of participants provided follow up data at 3-weeks post-release. Prior to incarceration participants had smoked an average of 21.5 (SD = 11.7) cigarettes per day. Only 29.2% had definite plans to remain smoking-abstinent after release. Approximately half of all participants reported that “most” or “all” of their family (42.2%) and friends (68%) smoked, and 58.8% reported their spouse or romantic partner smoked.
SSQ scores were not significantly predictive of smoking outcomes at three weeks, however, social support from family and friends were each significantly and positively correlated with motivation, confidence, and plans for remaining abstinent (all p values
Conclusions:
Inmates of smoke-free prisons have a head-start on being smoke-free for life. They have been abstinent well past the duration of nicotine withdrawal and have great financial incentive not to begin smoking again. However, this advantage may be offset by a lack of non-smoking role models among their family and friends, and perceived lack of support for remaining smoke-free.

The association between impulsivity and alcohol/drug use among prison inmates
Background: Few studies have examined the relation between impulsivity and drug involvement with prison inmates, in spite of their heavy drug use. Among this small body of work, most studies look at clinically relevant drug dependence, rather than drug use specifically.
Method: N = 242 adult inmates (34.8% female, 52% White) with an average age of 35.58 (SD = 9.19) completed a modified version of the 15-item Barratt Impulsiveness Scale (BIS) and measures assessing lifetime alcohol, opiate, benzodiazepine, cocaine, cannabis, hallucinogen, and polysubstance use. Lifetime users also reported the frequency of use for the 30 days prior to incarceration.
Results: Impulsivity was higher among lifetime users (versus never users) of all substances other than cannabis. Thirty day drug use frequency was only related to impulsivity for opiates and alcohol.
Discussion: This study extends prior work, by showing that a lifetime history of non-clinical substance use is positively associated with impulsivity among prison inmates. Implications for drug interventions are considered for this population, which is characterized by high rates of substance use and elevated impulsivity
HIV Continuum of Care for Youth in the United States
BACKGROUND:
Beneficial HIV treatment outcomes require success at multiple steps along the HIV Continuum of Care. Youth living with HIV are a key population, and sites in the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) are known for modeling optimum HIV adolescent care.
METHODS:
A longitudinal cohort study conducted at 14 network sites across the United States assessed how the later steps of the Continuum of Care were achieved among the youth: engagement, treatment, and viral load (VL) suppression. Youth aged 13-24 who were behaviorally infected with HIV and linked to care at an ATN-affiliated site were eligible to participate.
RESULTS:
A total of 467 youth were enrolled and had 1 year of available data. Most were aged 22-24 (57%), male (79%), and black/non-Hispanic (71%). Most used alcohol (81%) and marijuana (61%) in the 3 months before enrollment, and 40% had a history of incarceration. Among this cohort of youth, 86% met criteria for care engagement; among these, 98% were prescribed antiretroviral therapy and 89% achieved VL suppression. Sustained VL suppression at all measured time points was found among 59% with initial suppression. Site characteristics were notable for the prevalence of adherence counseling (100%), case management (100%), clinic-based mental health (93%), and substance use (64%) treatment.
CONCLUSIONS:
Youth living with HIV in the United States can be successfully treated at health care sites with experience, excellence, and important resources and services. Sustained VL suppression may be an important step to add to the Continuum of Care for youth
Changes in Depression and Stress after Release from a Tobacco-Free Prison in the United States
Prior research has found high levels of depression and stress among persons who are incarcerated in the United States (U.S.). However, little is known about changes in depression and stress levels among inmates post-incarceration. The aim of this study was to examine changes in levels of depression and stress during and after incarceration in a tobacco-free facility. Questionnaires that included valid and reliable measures of depression and stress were completed by 208 male and female inmates approximately eight weeks before and three weeks after release from a northeastern U.S. prison. Although most inmates improved after prison, 30.8% had a worsening in levels of depression between baseline and the three-week follow-up. In addition, 29.8% had a worsening in levels of stress after release than during incarceration. While it is not surprising that the majority of inmates reported lower levels of depression and stress post-incarceration, a sizable minority had an increase in symptoms, suggesting that environmental stressors may be worse in the community than in prison for some inmates. Further research is needed to address depression and stress levels during and after incarceration in order for inmates to have a healthier transition back into the community and to prevent repeat incarcerations
A typology of alcohol consumption among young people – A narrative synthesis
Background: Currently, alcohol consumption levels are significantly higher among younger age groups. However, previous research has noted the diversity of motivations and patterns. These patterns of drinking have yet to be synthesised into a typology. The aim of the current study was to synthesise information from studies that produced types of alcohol consumption among young people. Method: Quantitative and qualitative literature investigating the different types of drinkers among young people [aged 12–24 years], published in peer reviewed journals, were eligible for inclusion in this systematic review. MEDLINE, PsychInfo and CINAHL were systematically searched for relevant articles published between January 1st 2000 and December 31st 2014. Included papers were critically appraised. A narrative synthesis approach was employed based on guidance from the UK Economic and Social Research Council. Results: In total, 13 studies were eligible for inclusion: 11 quantitative, one qualitative and one mixed methods. Six classes of drinkers were formed within this typology. Abstainers reported no alcohol consumption. Light drinkers reported drinking small amounts of alcohol infrequently. In comparison, social and hedonistic drinkers drank most in social situations and to have fun. Heavy and harmful consumers reported increased volume and frequency of consumption including harmful consequences. Conclusion: Currently, policy makers are attempting to combat the high levels of harmful alcohol consumption among young people. The current typology provides guidance for targeted interventions in addition to a practical analytic tool in future research
Improving rigid fiberoptic intubation: a comparison of the Bonfils Intubating Fiberscope™ with a novel modification
<p>Abstract</p> <p>Background</p> <p>The Bonfils intubating fiberscope has a limited upward tip angle of 40° and requires retromolar entry into the hypopharynx. These factors may make its use less desirable when managing the difficult airway because most anesthesia providers are well versed in midline oral intubation rather than the lateral retromolar approach. The <it>Center for Advanced Technology and Telemedicine </it>at the University of Nebraska Medical Center has developed a novel fiberscope with a more anterior 60° curve to allow for easier midline insertion and intubation. The objective of this work was to evaluate the novel fiberscope, in comparison to the Bonfils intubating fiberscope, in terms of use and function in difficult airway intubation.</p> <p>Methods</p> <p>Twenty-two anesthesia providers participated in simulated intubations of a difficult airway mannequin to compare the Bonfils intubating fiberscope with the novel curved Boedeker intubating fiberscope. The intubations were assessed based upon the following variables: recorded Cormack Lehane airway scores, requests for cricoid pressure, time to intubation, number of intubation attempts and success or failure of the procedure.</p> <p>Results</p> <p>Participants using the Bonfils fiberscope recorded an average Cormack Lehane (CL) airway score of 1.67 ± 1.02 (median = 1); with the novel fiberscope, the recorded average airway grade improved to 1.18 ± 0.50 (median = 1). The difference in airway scores was not statistically significant (p = 0.34; Fishers Exact Test comparing CL grades 1&2 vs. 3&4). There was, however, a statistically significant difference in intubation success rates between the two devices. With the Bonfils fiberscope, 68% (15/22) of participants were successful in intubation compared to a 100% success rate in intubation with the novel fiberscope (22/22) (p = 0.008). After the intubation trial, the majority of participants (95%) indicated a preference for the novel fiberscope (n = 20).</p> <p>Conclusions</p> <p>With this data, we can infer that the novel fiberscope curvature appears to improve or maintain the quality of an intubation attempt (airway score, cricoid pressure requirement, intubation time, number of attempts, placement success). The data indicate that the novel fiberscope offers a superior intubation experience to currently available best practices. The instrument was well received and would be welcomed by most study participants should the device become clinically available in the future.</p
Vulnerability of Illinois nature preserves to potential ground-water contamination volume I: methodology and initial assessment
"Prepared for Illinois Nature Preserves Commission.""March 1997."The Illinois Nature Preserves Commission (INPC) was created by the Illinois Natural
Areas Preservation Act in 1963 (ch. 105, para. 701 et. seq.), with the mission to
"assist...landowners in protecting high quality natural areas and habitats of endangered and
threatened species in perpetuity, through voluntary dedication of such lands into the Illinois
Nature Preserves System." Dedication as a nature preserve provides strong legal protection. For
example, penalties for damaging a nature preserve range from a Class A misdemeanor to
$10,000 per day in civil penalties. As of December 1996, the Illinois Nature Preserve System
consisted of 261 nature preserves that encompass more than 35,000 acres (14,200 hectares) in 73
of the 102 Illinois counties.
A significant threat to nature preserves (and other areas with high quality natural
communities) is adjacent land use. Variability in adjacent land use generally depends on
preserve size and location. Frequently, many different land uses surround a single nature
preserve. Potential ground-water contaminant sources include: dumping within or near a
preserve, residential septic systems, roads where deicers are used, agricultural fields or feedlots,
leaking impoundments or storage tanks, and certain industrial and commercial activities.
Unfortunately, the lack of baseline data at most preserves prevents the detection of water quality
degradation from off-site activities.
During this study, methods were developed and utilized to assess nature preserve
sensitivity and vulnerability to potential ground-water contamination. First, a shallow
ground-water sensitivity map of the state (1:500,000) was prepared using GIS techniques. It predicts the
potential for movement of contaminants from the surface into shallow ground water based on
soil leaching characteristics and depth to the uppermost aquifer. Two hundred seven nature
preserves were screened, and nearly half of them were categorized as having high or very high
sensitivity to ground-water contamination.
Second, site surveys were conducted at the 85 nature preserves, which were expected to
be most sensitive to ground-water contamination. Hydrologic, geologic, and land-use
information was collected for the sites and surrounding areas prior to the surveys. These data
were used during the surveys and can be used for future interpretations and comparisons.
Roughly 30% of the sites were classified as having moderate-to-high or high vulnerability. The
development and use of a field evaluation form facilitated site surveys and the subsequent entry
of field data into an electronic database. These types of surveys should be conducted at all nature
preserves to provide a standard set of background information for future decision making.
Third, the geology and hydrology of Spring Grove Fen Nature Preserve in McHenry
County were characterized in greater detail. Test drilling was conducted and 10 observation
wells were installed. A total of 64 sets of ground-water and surface water samples were collected
between August 1995 and October 1996 and analyzed for a minimum of 35 constituents.
Increased chloride concentrations (up to 121 mg/L) were observed in and upgradient of the
preserve. Use of deicers on nearby roads may be responsible for an increase in chloride of over
500% at well SG-1a. Low concentrations of alachlor metabolites (< 3
μg/L) were seen in
observation wells and in Nippersink Creek. Low concentrations of triazine residues (< 1 μg/L)
were also seen in Nippersink Creek. Chemical data at Spring Grove Fen supports the assessment
of the site being highly vulnerable to contamination. This type of chemical sampling is
important to establish existing water quality at preserves for comparison to future conditions.
Information collected during this study is intended to facilitate petitions for state
designation of ground water associated with a nature preserve as a Special Resource Ground
Water. As stated in the Illinois Administrative Code (Title 35, Part 620.230), Special Resource
Ground Water is: a) "demonstrably unique...," or b) "vital for a particularly sensitive ecological
system...," or c) "groundwater that contributes to a dedicated nature preserve...." Such a
designation may then provide an additional level of protection against destruction or degradation
of nature preserves
Atopic dermatitis and food sensitization in South African toddlers: Role of fiber and gut microbiota
The pathogenesis of atopic dermatitis (AD) is complex and related to allergic responses and defects in skin barrier function. In common with many atopic diseases, the prevalence of AD has been increasing across the world.1 One of the theories for this increase is increased hygiene and urbanization-related changes in the environment, which can affect the human microbiome.2 Previous studies have found associations between the composition of the early gut microbiome and development of atopic conditions, including AD.3 Although the rate of atopic conditions, including AD and food allergy, is increasing on all continents, the prevalence of these diseases is still lower in African countries.1 This is especially interesting because individuals of African origin who live in Western countries, such as African Americans, are at a higher risk for severe AD.4 This variation places Africa in a special position; studying African populations is necessary not only to find ways to prevent increases of allergy conditions in African countries but also to provide important clues to the causes of this global increasing of allergic conditions. Young children who have developed AD in African communities with a low incidence of atopic disease might be the transitional group. In the current study, we have, for the first time to our knowledge, analyzed the fecal microbiota composition of a group of young black African children aged 12 to 36 months old with and without AD living in the same community in Cape Town, South Africa. Our primary goal was to examine whether toddlers with AD and control toddlers from Cape Town have different microbiomes in terms of bacterial richness and diversity. We also aimed to investigate the differences in the relative abundance for different operational taxonomic units between these 2 groups. In our subgroup analyses, we further tested the effect of multiple environmental factors on the gut microbiome in these children
Karyotype differentiation of four Cestrum species (Solanaceae) revealed by fluorescent chromosome banding and FISH
The karyotypes of four South American species of Cestrum (C. capsulare,C. corymbosum,C. laevigatum and C. megalophylum) were studied using conventional staining, C-CMA/DAPI chromosome banding and FISH with 45S and 5S rDNA probes. The karyotypes showed a chromosome number of 2n = 2x = 16, with metacentric chromosomes, except for the eighth submeta- to acrocentric pair. Several types of heterochromatin were detected, which varied in size, number, distribution and base composition. The C-CMA+ bands and 45S rDNA were located predominantly in terminal regions. The C-CMA + /DAPI + bands appeared in interstitial and terminal regions, and the C-DAPI + bands were found in all chromosome regions. The 5S rDNA sites were observed on the long arm of pair 8 in all species except C. capsulare, where they were found in the paracentromeric region of the long arm of pair 4. The differences in band patterns among the species studied here, along with data from other nine species reported in the literature, suggest that the bands are dispersed in an equilocal and non-equilocal manner and that structural rearrangements can be responsible for internal karyotype diversification. However, it is important to point out that the structural changes involving repetitive segments did not culminate in substantial changes in the general karyotype structure concerning chromosome size and morphology
Brain health: the importance of recognizing cognitive impairment: an IAGG consensus conference
Cognitive impairment creates significant challenges for patients, their families and friends, and clinicians who provide their health care. Early recognition allows for diagnosis and appropriate treatment, education, psychosocial support, and engagement in shared decision-making regarding life planning, health care, involvement in research, and financial matters. An IAGG-GARN consensus panel examined the importance of early recognition of impaired cognitive health. Their major conclusion was that case-finding by physicians and health professionals is an important step toward enhancing brain health for aging populations throughout the world. This conclusion is in keeping with the position of the United States' Centers for Medicare and Medicaid Services that reimburses for detection of cognitive impairment as part the of Medicare Annual Wellness Visit and with the international call for early detection of cognitive impairment as a patient's right. The panel agreed on the following specific findings: (1) validated screening tests are available that take 3 to 7 minutes to administer; (2) a combination of patient- and informant-based screens is the most appropriate approach for identifying early cognitive impairment; (3) early cognitive impairment may have treatable components; and (4) emerging data support a combination of medical and lifestyle interventions as a potential way to delay or reduce cognitive decline
