Protecting children and families from tobacco and tobacco-related NCDs in the Western Pacific: good practice examples from Malaysia, Philippines and Singapore

BACKGROUND

Non-communicable diseases (NCDs) are generally considered diseases of adulthood, but NCD risk factors like tobacco use often are taken up during childhood and adolescence, and second-hand smoke exposure affects child survival and development.

METHODS

At a regional meeting of the Asia Pacific Child and Family Health Alliance for Tobacco Control, members reviewed existing good practices of child-focused tobacco control approaches using health promotion strategies. These interventions were implemented nationally in Malaysia, the Philippines and Singapore.

RESULTS

Three good practice national examples were identified that focused on creating supportive tobacco-free environments and upgrading cessation skills among paediatricians. These country examples highlight strategic areas to protect children and families from the harms of tobacco, as part of NCD prevention and control. Training paediatricians in brief cessation advice has enabled them to address tobacco-using parents. Fully enforcing smoke-free public areas has led to an increase in smoke-free homes. The Tobacco Free Generation is a tobacco control 'endgame' strategy that taps into a social movement to deglamorize tobacco use and empower youth born in and after year 2000 to reject tobacco and nicotine addiction.

CONCLUSION

Tobacco control is pivotal in the fight against NCDs; health promotion strategies to protect children and youth from tobacco have a critical role to play in NCD prevention and control. Frontline health workers, including primary care paediatricians, need to step up and actively advocate for full implementation of the WHO Framework Convention on Tobacco Control, including tobacco tax increases and smoke-free areas, while monitoring patients and their parents for tobacco use and second-hand smoke exposure, preventing adolescent smoking uptake, and offering cessation support. A life-course approach incorporating child-focused efforts to prevent initiation of smoking and second-hand smoke exposure with measures promoting cessation among parents will offer the greatest chance of overcoming future tobacco-related NCD burden.

Closer versus Long Range Interaction Effects on the Non-Arrhenius Behavior of Quasi-Resonant O2 + N2 Collisions

We report in this paper an investigation on energy transfer processes from vibration to vibration and/or translation in thermal and subthermal regimes for the O₂ + N₂ system performed using quantum-classical calculations on different empirical, semiempirical, and ab initio potential energy surfaces. In particular, the paper focuses on the rationalization of the non-Arrhenius behavior (inversion of the temperature dependence) of the quasi-resonant vibration-to-vibration energy transfer transition rate coefficients at threshold. To better understand the microscopic nature of the involved processes, we pushed the calculations to the detail of the related cross sections and analyzed the impact of the medium and long-range components of the interaction on them. Furthermore, the variation with temperature of the dependence of the quasi-resonant rate coefficient on the vibrational energy gap between initial and final vibrational states and the effectiveness of quantum-classical calculations to overcome the limitations of the purely classical treatments were also investigated. These treatments, handled in an open molecular science fashion by chaining data and competencies of the various laboratories using a grid empowered molecular simulator, have allowed a rationalization of the dependence of the computed rate coefficients in terms of the distortion of the O₂-N₂ configuration during the diatom-diatom collisions. A way of relating such distortions to a smooth and continuous progress variable, allowing a proper evolution from both long to closer range formulation of the interaction and from its entrance to exit channel (through the strong interaction region) relaxed graphical representations, is also discussed in the paper.

The American Society for Clinical Pathology's 2015 Wage Survey of Medical Laboratories in the United States

OBJECTIVES

To inform the pathology and laboratory field of the most recent national wage data from the American Society for Clinical Pathology (ASCP). Historically, the results of this biennial survey have served as a basis for additional research on laboratory recruitment, retention, education, marketing, certification, and advocacy.

METHODS

The 2015 wage survey was conducted through collaboration between the ASCP's Institute of Science, Technology, & Policy in Washington, DC, and the ASCP Board of Certification in Chicago, Illinois. Electronic survey invitations were sent to individuals who are currently practicing in the field.

RESULTS

Data reveal increased salaries since 2013 for all staff-level laboratory professionals surveyed except phlebotomists and pathologists' assistants. Laboratory assistants and phlebotomists, regardless of level, continue to have lower salaries while pathologists' assistants and administration personnel have higher salaries than the rest of the laboratory professions surveyed.

CONCLUSIONS

Survey results put emphasis on strategic recruitment and retention by laboratory training programs and institutions that hire laboratory professionals.

The link between developmental psychiatry and dual disorders from early attachment to first drugs abuse

Since Dual Disorders expression was used for the first time, the old dilemma between cathegorial and dimensional grew again as a main issue because many authors wondered about its utility. The question was how far we can speak about two different entities, because doing so we are assuming comorbidity instead of a complex syndrome, with different clinical presentations (i.e. Talking about fever and cough instead of pneumonia). Child and adolescence psychiatry uses developmental psychiatry as a very useful tool to understand patients. Syndromes are seen as dynamic as patients. At the same time that patients grow their clinical presentations, evolves new symptoms or signs. We have reviewed retrospectively a group of twenty parents that were named as dual disorders, with different substance abuse but a common path in their childhood; all of them were diagnosed of ADHD and Conduct Disorder. We chose them because of the differences that DSM, ICD and main researchers have about this group, which some consider better described as a Disocial hiperquinetic disorder (ICD) than a AHDH with a conduct disorder associated (DSM), comorbidity again. We agreed with ICD opinion and will discuss how in some way we are somehow as those blind people describing different parts of the same elephant when we talk sometimes about dual. Truth is that opposite dual view or its syndromic treatment developmental psychiatry has all the time underlined the role of reward circuits/executive functions as epigenetic issues, both modulated by gene and environment.

Characterisation of new gated optical image intensifiers for fluorescence lifetime imaging

We report the characterisation of gated optical image intensifiers for fluorescence lifetime imaging, evaluating the performance of several different prototypes that culminate in a new design that provides improved spatial resolution conferred by the addition of a magnetic field to reduce the lateral spread of photoelectrons on their path between the photocathode and microchannel plate, and higher signal to noise ratio conferred by longer time gates. We also present a methodology to compare these systems and their capabilities, including the quantitative readouts of Förster resonant energy transfer.

Preserved vagus nerve stimulator function after radiation therapy

BACKGROUND

Epilepsy and breast cancer are both prevalent conditions. A subset of women with medically refractory epilepsy and vagus nerve stimulators (VNS) may later develop breast cancer and may require adjuvant radiation as part of their treatment regimen. However, to date, little data are available on the effects of radiation on VNS function.

CASE PRESENTATION

We present a young woman with tuberous sclerosis, developmental delay, and medically refractory epilepsy who developed left-sided breast cancer. Her epilepsy became controlled with a recent addition of a VNS implanted in her left chest wall. She required adjuvant radiation therapy to her left breast, and this raised the novel question of the safety of radiation on the integrity and functioning of the device, which we explore in this article.

CONCLUSION

This case is the first report of a patient with VNS for epilepsy and breast cancer who received radiation therapy proximal to the device. The device continued to function properly despite the exposure.

A Single-Blind Randomized Trial About the Effect of Hydrogen Peroxide Concentration on Light-Activated Bleaching

Objective: To compare the bleaching efficacy and tooth sensitivity (TS) of two hydrogen peroxide (HP) concentrations (20% and 35%) used for in-office bleaching associated or not with a light-emitting diode (LED)/laser light activation.

Method: Seventy-seven patients with a right maxillary canine darker than A3 were selected for this single-blind randomized trial. The participants were distributed in four groups: bleaching with 35% HP, 35% HP + LED/laser, 20% HP, and 20% HP + LED/laser. The anterior teeth were bleached in two sessions, using a 35% or 20% HP gel with a one-week interval. Each session had three applications of 15 minutes. For the light-activated groups, the LED/laser energy (Whitening Laser Light Plus, DMC) was employed according to the manufacturer's instructions. The color change was evaluated by subjective and objective methods. Participants recorded TS with five-point verbal and visual analog scales. Color change in ΔE was evaluated by analysis of variance and Tukey tests (α=0.05) and in ΔSGU with Kruskall-Wallis and Dunn test. The absolute risk of TS and TS intensity were evaluated by Fisher exact test and Kruskall-Wallis test, respectively (α=0.05).

Results: All groups achieved the same level of whitening, except for the 20% HP group, which showed the lowest degree of whitening in the subjective analysis. The use of light did not increase the absolute risk or intensity of TS. No significant difference among groups was observed when color changes were assessed with the spectrophotometer.

Conclusion: According to the value-oriented shade guide, the use of LED/laser light activation was able to increase the degree of whitening of the 20% HP group, but this association was not useful for the 35% HP gel. The spectrophotometer, however, did not detect significant differences among groups.

Enhanced Flexibility of the O2 + N2 Interaction and Its Effect on Collisional Vibrational Energy Exchange

Prompted by a comparison of measured and computed rate coefficients of Vibration-to-Vibration and Vibration-to-Translation energy transfer in O2 + N2 non-reactive collisions, extended semiclassical calculations of the related cross sections were performed to rationalize the role played by attractive and repulsive components of the interaction on two different potential energy surfaces. By exploiting the distributed concurrent scheme of the Grid Empowered Molecular Simulator we extended the computational work to quasiclassical techniques, investigated in this way more in detail the underlying microscopic mechanisms, singled out the interaction components facilitating the energy transfer, improved the formulation of the potential, and performed additional calculations that confirmed the effectiveness of the improvement introduced.

Experimental evaluation of the Dideco Masterflo paediatric hollow-fibre membrane oxygenator

Nine mongrel dogs (mean bodyweight: 29 ± 6kg) were connected to cardiopulmonary bypass byfemorojugularvenous and femoral arterial cannulation, classic roller pump and the integrated Dideco D702 Masterflo hollow-fibre membrane oxygenatorwith a mean flow rate of 70ml/kg/min for six hours. Then the animals were weaned from cardiopulmonary bypass and thereafter weaned from the ventilator. After seven days all animals were sacrificed electively for necropsy. A standard battery of blood samples was taken before the bypass, after mixing (10 minutes), after two hours, five hours and six hours of perfusion. Further samples were taken 30 minutes after bypass (spontaneous breathing), 60 minutes after bypass (after extubation), 24 hours after bypass, 48 hours after bypass and seven days after bypass. Physiologic blood gas values could be maintained throughout perfusion in all animals. Mean arterial oxygen saturation varied between 99.7% and 99.9% for the arterial side of the oxygenator compared to 77.8% and 86.6% on the venous side. Post bypass blood gas analyses showed physiologic values and no evidence of major lung trauma or pulmonary oedema in relation to the six hours' bypass. Red blood count was 5.84 ± 0.02 before and 4.63 + 0.1 million/mm3 after mixing and dropped to 3.89 ± 0.52 till the end of the bypass. After seven days the red blood count was practically normalized with over 5,000,000 erythrocytes per mm3 at the end of the observation. Blood trauma evaluated in function of plasma haemoglobin and (thrombocyte) depletion showed the following results: prebypass: 2.3 ± 0.7 μmol/l plasma haemoglobin and (220 ± 24 thousand thrombocytes per mm3); after six hours perfusion: 26.2 ± 15.5 and (137 ± 12); after seven days: 9.3 ± 4.1 and (400 ± 125). Post mortem studies did not demonstrate any deleterious lesions.

Efficiency of Collisional O2 + N2 Vibrational Energy Exchange

By following the scheme of the Grid Empowered Molecular Simulator (GEMS), a new O2 + N2 intermolecular potential, built on ab initio calculations and experimental (scattering and second virial coefficient) data, has been coupled with an appropriate intramolecular one. On the resulting potential energy surface detailed rate coefficients for collision induced vibrational energy exchanges have been computed using a semiclassical method. A cross comparison of the computed rate coefficients with the outcomes of previous semiclassical calculations and kinetic experiments has provided a foundation for characterizing the main features of the vibrational energy transfer processes of the title system as well as a critical reading of the trajectory outcomes and kinetic data. On the implemented procedures massive trajectory runs for the proper interval of initial conditions have singled out structures of the vibrational distributions useful to formulate scaling relationships for complex molecular simulations.

Case report: Hallucinations as depressive equivalents

We comment the case of a 12 years old girl who started with visual and auditive hallucinations. Hallucinations are not a common symptom between children. They may also be linked to many conditions, some of them with poor outcome as schizophrenia. Symptoms appeared in a short time, after a previous normal development. She talked about a man who followed her and that was always behind, she also had heard some insults of undeterminated voices. These symptoms were just of one-month duration and made her feel anxious and very afraid. After a normal organical study and a first proposal of medication they asked for our consultation. We found that the patient was alone at home every afternoon. Family, from other country, hadn’t any social support, and the father had had to travel away some days before the child began to suffer hallucinations. Suspecting an affective disorder as the basis of anxious symptoms, and hallucinations as a cultural presentation of them, we started with a social intervention mixed with support therapy. After some sessions the patient could talk about her loneliness and fears, disappearing the other symptoms. We will resume this case and literature about other cultural presentations that may difficult diagnosis or treatment.

Related factors with substance use in old adults

Intro

Substance use disorder is a growing phenomenon among the elderly. It is undervalued, misidentified, underdiagnosed and poorly treated.

Aim

Study prevalence, characteristics and risk factors associated with drug use among the elderly.

Method

A 6-month prospective study of substance use in elderly patients (65+) who attended the addiction and dual diagnosis unit, Vall d’Hebron University Hospital.

Results

Fifty-nine patients evaluated, mean age 70.04 years, 60% men. A total of 49.1% are married, 35.8% divorced and 53.8% live with a partner and/or children. A total of 67.3% have basic studies and 78.8% are pensioners. A total of 82.7% have no criminal record.

Medical comorbidity presents in 90.4% of the sample, psychiatric and addictive family background in 42.3% and 37.3%. A total of 67.3% have comorbid Axis I (mainly affective disorders) and 25% Axis II (cluster B most). A total of 7.7% attempted suicide at least once.

The main substance is alcohol (76.9%), followed by prescription drugs (19.3%). A total of 28.8% are multi-drug users. A total of 67.3% have used tobacco in their life and 63.5% are currently dependent. The average age of onset for a disorder for any substance consumption is 28.19, being lower for alcohol and illegal substances and higher for prescription drugs.

A total of 61.5% have gone through treatment before but only 32.7% has been admitted because of addiction. The adherence rate is 90.4% and the relapse rate 8.3% at first month and 13% at 6 months.

Conclusions

Old adults present differences compared to overall drug user population: prevalence by gender is almost equal, lower Axis II, less multi-drug consumption and both dropout and relapse rate are drastically lower.
