Organisational justice and smoking: the Finnish Public Sector Study

Study Objective: To examine the extent to which justice of decision-making procedures and interpersonal relations is associated with smoking. Setting: Ten municipalities and 21 hospitals in Finland. Design and Participants: Cross-sectional data derived from the Finnish Public Sector Study were analysed with logistic regression analysis models with generalized estimating equations. Analyses of smoking status were based on 34 021 employees. Separate models for heavy smoking (>20 cigarettes per day) were calculated for 6295 current smokers. Main results: After adjustment for age, education, socio-economic position, marital status, job contract, and negative affectivity, smokers who reported low procedural justice were about 1.4 times more likely to smoke >20 cigarettes per day compared with their counterparts with high justice. In a similar way, after adjustments, low justice in interpersonal treatment was significantly associated with an elevated prevalence of heavy smoking (odds ratio (OR) = 1.35, 95% CI = 1.03 to 1.77 for men and OR = 1.41, 95% CI = 1.09 to 1.83 for women). Further adjustment for job strain and effort-reward imbalance had little effect on these results. There were no associations between justice components and smoking status or ex-smoking. Conclusions: The extent to which employees are treated with justice in the workplace seems to be associated with smoking intensity independently of established stressors at work.

TGA/FTIR study of the pyrolysis of diammonium hydrogen phosphate–tobacco mixtures

Diammonium hydrogen phosphate (DAP) is commonly used as a flavor ingredient of commercial cigarettes. In addition, among its other uses, it is employed to expand the tobacco volume, to manufacture reconstituted tobacco sheet, and to denicotinize tobacco. However, the use of DAP as a cigarette ingredient is a controversial issue. Some authors have stated that ammonium compounds added to tobacco increase smoke ammonia and “smoke pH”, resulting in more free nicotine available in the smoke. On the other hand, other researchers have reported that the larger ammonium content of a cigarette blend due to the presence of DAP was not reflected in increased smoke ammonia. In this work, the thermal behavior of DAP, tobacco and DAP-tobacco mixtures has been studied by TGA/FTIR. The chemical processes involved in the different pyrolysis steps of DAP have been suggested. Marked changes in the pyrolytic behavior of both, tobacco and DAP have been detected when analyzing the behavior of the mixtures. A displacement of the decomposition steps mainly related to the glycerol and lignin from tobacco toward lower temperatures has been observed, whereas that associated with cellulose is displaced toward higher temperature. Additionally, no peak corresponding to the phosphorous oxides decomposition has been detected in the curves relating to the DAP-tobacco mixtures. All these features are indicative of the strong interactions between DAP and tobacco. The FTIR spectra show no significant qualitative differences between the qualitative overall composition of the gases evolved from the pyrolysis of tobacco in the absence and in the presence of DAP. Nevertheless, depending on the temperature considered, the addition of DAP contributes to a decrease in the generation of hydrocarbons and an increase in the formation of CO, CO2 and oxygenated compounds in terms of amount generated per mass of pyrolysed tobacco.

Evidencia sobre la eficacia de cannabinoides en el dolor neuropático oncológico

Contexto: La eficacia de los cannabinoides en el dolor neuropático es desconocida. El control del dolor es determinante en los pacientes ya que genera un impacto negativo en la calidad de vida de los pacientes. Objetivo: El presente trabajo pretende demostrar la evidencia sobre la eficacia de los medicamentos cannabinoides en el control del dolor neuropático oncológico, mediante la evaluación de la literatura disponible. Metodología: Se realizó una revisión sistemática de literatura incluyendo estudios experimentales, observacionales y revisiones sistemáticas en un periodo de 15 años. Se incluyeron todos los estudios desde el años 2000 con evidencia IB según la escala de evidencia de Oxford. Resultados: Cuatro estudios cumplieron criterios para su inclusión, sin embargo la evidencia es baja y no permite recomendar o descartar los cannabinoides como terapia coadyuvante en control del dolor neuropático oncológico. La combinación de THC/CDB (Sativex®) parece ser un medicamento seguro pues no se reportaron muertes asociadas a su uso, sin embargo la presentación de eventos adversos a nivel gastrointestinal y neurológico podría aumentar el riesgo de interacciones medicamentosas y tener un impacto negativo en la calidad de vida de los pacientes oncológicos. Conclusiones: No hay suficiente literatura y la evidencia no es suficiente para recomendar o descartar el uso de los cannabinoides en dolor neuropático oncológico. Futuros estudios deben realizarse para analizar el beneficio de estos medicamentos. Aunque ética y socialmente hay resistencia para el uso de los cannabinoides, actualmente hay una gran discusión política en el mundo y en Colombia para su aceptación como terapia en el control del dolor.

The psychoactive effects of “Light Cannabis”. From Italian law to psychopharmacology

In 2019, the Italian Supreme Court established that hemp, for non-medical use, cannot be commercialized for human use, when the “psychotropic effect” of the product or its “offensiveness” can be demonstrated. The first chapter of this work reports a review of the European and Italian legislation on hemp cultivation, as well as the hemp production chain and commercial activities. The second chapter reports the pharmacological aspects and the psychoactive effects of light cannabis, along with pharmacokinetics of the main Cannabis compounds: Δ9-tetrahydrocannabinol (Δ9-THC), Cannabidiol (CBD) and Cannabinol (CBN). The aim of the experimental study, reported in the third chapter, is to assess Δ9-THC and CBD blood concentrations after smoking “light cannabis”, and its effects on vigilance, cognitive and motor skills. Eighteen young adults consumed three light cannabis cigarettes with a percentage of 0.41% of Δ9-THC and of 12.41% of CBD. Blood samples were collected before the experiment (t0) and after pre-defined time-lapses. Five performance tasks and a subjective scale were employed for measuring cognitive and psychomotor performances the day before the experiment (TT0) and after the third cigarette (TT1). Mean (SD) concentrations (ng/ml) were between 1.0(0.8) in t1 and 0.3(0.3) in t5 for Δ9-THC; and 10.5(10.3) in t1 and 5.7(5.7) in t5 for CBD. No significant differences were observed between TT0 and TT1 for all performed psychomotor performance task. Δ9-THC and CBD concentrations showed a high inter-subject variability, and the average concentrations were lower than those previously reported. Toxicological results showed a decrease of Δ9-THC and CBD after the third light cannabis cigarette, and a Δ9-THC /CBD ratio always < 1 was observed. This value might be useful in discriminating light cannabis versus illegal/medical cannabis consumption. The lack of impairment observed in our participants can be interpreted as a consequence of the very low concentrations in the blood.

Prevention of binge drinking in young adolescents through the promotion of a balanced level of psychological well-being: be-dry

This doctoral thesis presents a project carried out in secondary schools located in the city of Ferrara with the primary objective of demonstrating the effectiveness of an intervention based on Well-Being Therapy (Fava, 2016) in reducing alcohol use and improving lifestyles. In the first part (chapters 1-3), an introduction on risky behaviors and unhealthy lifestyle in adolescence is presented, followed by an examination of the phenomenon of binge drinking and of the concept of psychological well-being. In the second part (chapters 4-6), the experimental study is presented. A three-arm cluster randomized controlled trial including three test periods was implemented. The study involved eleven classes that were randomly assigned to receive well-being intervention (WBI), lifestyle intervention (LI) or not receive intervention (NI). Results were analyzed by linear mixed model and mixed-effects logistic regression with the aim to test the efficacy of WBI in comparison with LI and NI. AUDIT-C total score increased more in NI in comparison with WBI (p=0.008) and LI (p=0.003) at 6-month. The odds to be classified as at-risk drinker was lower in WBI (OR 0.01; 95%CI 0.01–0.14) and LI (OR 0.01; 95%CI 0.01–0.03) than NI at 6-month. The odds to use e-cigarettes at 6-month (OR 0.01; 95%CI 0.01–0.35) and cannabis at post-test (OR 0.01; 95%CI 0.01–0.18) were less in WBI than NI. Sleep hours at night decreased more in NI than in WBI (p = 0.029) and LI (p = 0.006) at 6-month. Internet addiction scores decreased more in WBI (p = 0.003) and LI (p = 0.004) at post-test in comparison with NI. Conclusions about the obtained results, limitations of the study, and future implications are discussed. In the seventh chapter, the data of the project collected during the pandemic are presented and compared with those from recent literature.

Toxicological effects related to a novel heated tobacco product

The tobacco epidemic is a public health burden. Nicotine-Delivery-Systems(NDS) are devices designed to help people replace conventional cigarette(CC) and among these devices we find electronic cigarettes(e-cig), which are classified as Electronic-NDS(ENDS). E-cigs use different technologies to vaporize a liquid or to heat the tobacco avoiding the combustion phenomenon(IQOS). The US Food and Drug Administration(FDA) has labelled IQOS as modified risk tobacco products(MRTPs), indirectly encouraging the perception of safety in the consumers, but IQOS smoke, although to a lesser extent than conventional, still presents a great deal of harmful or potentially harmful compounds. My PhD thesis aims to study the toxic effects related to IQOS exposure. I sought to answer the question of whether the toxic compounds released by IQOS, albeit in reduced concentrations, could lead to genotoxicity and damage to the airways and liver in vivo. At the University of Nottingham, I have investigated in vitro the effects generated by the IQOS, e-cigs and CC exposure on PBMCs and human lung epithelial cell line. Finally, at University of Milano–Bicocca, I have developed a in vivo Positron Emission computed Tomography(PET) imaging procedure meant to be applied to the monitoring of ENDS toxicity, particularly in the brain. These results indicate that IQOS is not a low-risk product in vivo, for primary target organs but also for secondary organs, although we have observed a small impact in vitro. Labelling as MRTP may mislead consumers who interpret “a lower level of toxic compounds” as an indication of “harmlessness” when there is a health risk for users. In the last part, I set up a methodology for studying temporal fluctuations of regional brain metabolism and connectivity derived from mice of different ages allowing researchers to obtain normative values in investigations of the efficacy or toxicity of substances at the functional level of the CNS.
