Abstract
Cigarette smoke (CS) is a risk factor for chronic obstructive pulmonary disease (COPD), which can exacerbate inflammation and oxidative stress. Pristimerin (Pris) is a natural compound with antioxidant and anti-inflammatory effects. We managed to evaluate the protective effects of Pris on CS-induced COPD. The CS-induced COPD mice model and cell model were constructed. The effects of Pris treatment on lung function, inflammatory cell infiltration, myeloperoxidase (MPO), and pathological changes of lung tissues in mice model were evaluated. The impacts of Pris treatment on inflammatory factors, chemokines, and oxidative stress parameters in mice lung tissues and cells were determined by kits. The viability of human bronchial epithelial cells after Pris treatment was tested by CCK-8. The activation of NF-κB pathway was confirmed by Western blot and immunofluorescence. CS treatment impaired lung function, reduced weight of mice, and enhanced inflammatory cell infiltration, MPO, and lung tissue damage, but these effects of CS were reversed by Pris treatment. Furthermore, Pris treatment downregulated the levels of malondialdehyde, IL-6, IL-1β, TNF-α, CXCL1, and CXLC2, but upregulated superoxide dismutase and catalase levels. Pris treatment could overturn CS-induced activation of the NF-κB pathway. Pris alleviates CS-induced COPD by inactivating NF-κB pathway.

Eze JN, Ozoh OB, Otuu FC, Shu EN, Anyaehie BU. Respiratory symptoms and lung function among inmates in a Nigerian prison: a cross sectional study. BMC Pulm Med 2022; 22:84. [PMID: 35287649 PMCID: PMC8918425 DOI: 10.1186/s12890-022-01882-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 02/28/2022] [Indexed: 11/24/2022] Open
Abstract
Background Prisoners in low- and middle-income countries are vulnerable to poor lung health from multiple adverse conditions confronted within the prison such as overcrowding, poor ventilation and exposure to second hand smoke. Evidence for poor lung health in this disadvantaged group is needed to inform policy on prison conditions in this region. We assessed the respiratory symptoms and lung function measured by spirometry among prisoners in Enugu, Nigeria and explored the associations between them.
Methods This was a cross‑sectional study among prison inmates aged 16–76 years. We assessed frequency of respiratory symptoms in the preceding one-year, previous respiratory diagnosis, tobacco smoking status and spirometry. The relationships between respiratory symptoms, smoking status and spirometry pattern were determined using the Chi‑square test. Results Of 245 participants, 170 (69.4%) reported at least one respiratory symptom. In all, 214 (87.3%) performed spirometry and 173 (80.8%) had good quality spirometry tests. Using the Global Lung Function Initiative (GLI) predicted values for ‘African Americans’, spirometry results were abnormal in 41 (23.7%) of the participants and when the GLI reference values for ‘Other’ ethnic groups was applied, 78 (45.1%) had abnormal results. Restrictive impairment was most common occurring in 21 (12.1%) and 59 (34.1%) respectively based on the two reference values, and obstructive pattern was found in 18 (10.4%) and 13 (7.5%) respectively. There was no significant association between abnormal spirometry pattern and presence of respiratory symptoms or smoking status. No previous diagnosis for asthma, or bronchitis/chronic obstructive pulmonary disease (COPD) had been made in any of the participants. Conclusions We reported high rates of respiratory symptoms and abnormal lung function with under-diagnosis of chronic respiratory diseases among inmates in Enugu prison. The restrictive abnormalities based on GLI equations remain unexplained. There is need for improvement in prison facilities that promote lung health and enhanced access to diagnosis and treatment of respiratory non-communicable disease.

Abstract
To determine smoking behaviors, quit attempts, and cessation preferences among incarcerated smokers, a cross-sectional survey was given to a sample of inmates from three state prison facilities in the United States. A majority of Black smokers (62%) identified as smokers, and 38% identified as ex-smokers, as compared to 46.4 percent of smokers (and 53.6% of ex-smokers) in the non-Black group. There were significant differences in the number of cigarettes smoked per day with non-Black smokers smoking one pack (M = 20.44, standard deviation = 15.86) than Black smokers (M = 14.49, standard deviation = 13.43; t = -2.50, p = 0.014). Smoking cessation interventions are needed to reduce smoking during incarceration.

Epidemiol Rev 2018; 40:82-95.

Abstract
Smoking tobacco contributes to 11.5% of deaths worldwide and, in some countries, more hospitalizations than alcohol and drugs combined. Globally in 2015, 25% of men and 5% of women smoked. In the United States, a higher proportion of people in prison smoke than do community-dwelling individuals. To determine smoking prevalence in prisons worldwide, we systematically reviewed the literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines; we also examined whether prisons banned smoking or treated smokers. We searched databases for articles published between 2012 and 2016 and located 85 relevant articles with data representing 73.5% of all incarcerated persons from 50 countries. In 35 of 36 nations (97%) with published prevalence data, smoking for the incarcerated exceeded community rates 1.04- to 62.6-fold. Taking a conservative estimate of a 2-fold increase, we estimated that, globally, 14.5 million male and 26,000 female smokers pass through prisons annually. Prison authorities’ responses include permitting, prohibiting, or treating tobacco use. Bans may temporarily improve health and reduce in-prison health care costs but have negligible effect after prison release. Evidence-based interventions for smoking cessation effective outside prisons are effective inside; effects persist after release. Because smoking prevalence is heightened in prisons, offering evidence-based interventions to nearly 15 million smokers passing through yearly would improve global health.

Abstract
Substance use disorders are among the most common health problems of people involved with the criminal justice system. Scaling up addiction services in prisons is a global public health and human rights challenge, especially in poorly resourced countries. We systematically reviewed the prevalence of substance use in prison populations in low- and middle-income countries. We searched for studies reporting prevalence rates of nicotine, alcohol, illicit drug, and injection drug use during imprisonment in unselected samples of imprisoned people in low- and middle-income countries. Data meta-analysis was conducted and sources of heterogeneity were examined by meta-regression. Prevalence of nicotine use during imprisonment ranged from 5% to 87%, with a random-effects pooled estimate of 56% (95% confidence interval (CI): 45, 66) with significant geographical heterogeneity. Alcohol use varied from 1% to 76% (pooled prevalence, 16%, 95% CI: 9, 25). Approximately one-quarter of people (25%; 95% CI: 17, 33; range, 0–78) used illicit drugs during imprisonment. The prevalence of injection drug use varied from 0% to 26% (pooled estimate, 1.6%, 95% CI: 0.8, 3.0). Lifetime substance use was investigated in secondary analyses. The high prevalence of smoking in prison suggests that policies regarding smoking need careful review. Furthermore, the findings underscore the importance of timely, scalable, and available treatments for alcohol and illegal drug use by people involved with the criminal justice system.

Abstract
Background Morbidity, mortality and a wide range of associated risk factors are disproportionately clustered among prisoners compared to the general population. Smoking is one of the risk factors for the increased burden of unfavorable health outcomes particularly among prisoners. However, little is known about the level and determinants of smoking among the incarcerated population in Ethiopia. Methods We collected data from 738 prisoners in nine major prison setups in Tigray region by nurses and clinical officers. Data were entered in to Epi Data 3.1 and exported to stata 13.0 for cleaning and further analysis. Multivariable logistic regression model was fitted to identify determinants of smoking at p value of less than 5%. Result The prevalence of smoking was 21 per cent (95%CI = 18.2%, 24.1). Urban residence (AOR = 2.15; 95%CI = 1.20, 3.84), previous history of incarceration (AOR = 1.91; 95%CI = 1.08, 3.40) and alcohol use before incarcerated (AOR = 4.20; 95%CI = 2.57, 6.87) were significantly associated with risk of smoking. In contrast, risk of smoking was significantly lower for farmers (AOR = 0.20; 95% CI = 0.08, 0.49), prisoners with family support (AOR = 0.52; 95% CI = 0.32, 0.87) and for those who were jailed in Shire prison site (AOR = 0.43; 95%CI = 0.20, 0.95). Conclusion Our work clearly indicates that the observed smoking prevalence calls for the need of comprehensive and interdisciplinary interventions targeting prisoners.

Abstract
Objective We conducted a systematic review to examine the impact of smoking cessation interventions, including smoking bans, on prisoners and prison staff. Data sources We systematically searched health and criminal justice databases for relevant studies. Search strings were used to combine terms related to smoking cessation interventions with terms related to incarceration. We used forward and backward snowballing to capture additional studies. Study selection Studies were included if: they were published between 1 January 1994 and 23 May 2016; the population was incarcerated adults and/or prison staff; they had a quantitative component; they were published in English; and they reported outcomes of a smoking cessation programme/ban with regard to reported change in smoking behaviour and/or behavioural outcomes. Data extraction Studies were reviewed for methodological rigour using the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies. Data were independently reviewed for methodological quality by 1 author and a research assistant. Data synthesis Cessation programmes, including free nicotine replacement therapy and/or behavioural counselling can significantly increase the likelihood of quitting in prison and increase abstinence postrelease. Indoor bans have little impact on prisoner smoking behaviour. Prisoners who experience a complete smoking ban typically resume smoking shortly after release from prison. Bans may result in adverse behavioural outcomes, but these are generally minimal and short-lived. Conclusions While there is limited evidence to inform tobacco control policies in custodial settings, outcomes of this review suggest that cessation programmes/bans can be an effective mechanism to interrupt prisoner smoking behaviour when properly enforced.

Abstract
OBJECTIVE Cigarette smoking is the main cause of chronic obstructive pulmonary disease (COPD) and may modulate the immune response of exposed individuals. Mast cell function can be altered by cigarette smoking, but the role of smoking in COPD remains poorly understood. The current study aimed to explore the role of cigarette smoke extract (CSE)-treated mast cells in COPD pathogenesis. METHODS Cytokine and chemokine expression as well as degranulation of bone marrow-derived mast cells (BMMCs) were detected in cells exposed to immunoglobulin E (IgE) and various doses of CSE. Adoptive transfer of CSE-treated BMMCs into C57BL/6J mice was performed, and macrophage infiltration and polarization were evaluated by fluorescence-activated cell sorting (FACS). Furthermore, a coculture system of BMMCs and macrophages was established to examine macrophage phenotype transition. The role of protease serine member S31 (Prss31) was also investigated in the co-culture system and in COPD mice. RESULTS CSE exposure suppressed cytokine expression and degranulation in BMMCs, but promoted the expressions of chemokines and Prss31. Adoptive transfer of CSE-treated BMMCs induced macrophage infiltration and M2 polarization in the mouse lung. Moreover, CSE-treated BMMCs triggered macrophage M2 polarization via Prss31 secretion. Recombinant Prss31 was shown to activate interleukin (IL)-13/IL-13Rα/Signal transducers and activators of transcription (Stat) 6 signaling in macrophages. Additionally, a positive correlation was found between Prss31 expression and the number of M2 macrophages in COPD mice. CONCLUSION In conclusion, CSE-treated mast cells may induce macrophage infiltration and M2 polarization via Prss31 expression, and potentially contribute to COPD progression.
