Household air pollution and respiratory health in rural Crete, Greece: a cross-sectional FRESH AIR study

Breathing polluted air is a risk to respiratory conditions. During the Greek financial crisis, the use of household fireplaces/wood stoves shifted from mostly decorative to actual domestic heating, resulting in increased indoor smoke production. We aimed to evaluate household air pollution (HAP), fuel use and respiratory symptoms in rural Crete, Greece. PM2.5 and CO were measured in 32 purposively selected rural households (cross-sectional study) at periods reflecting lesser (baseline) versus extensive (follow-up) heating. Clinical outcomes were assessed using questionnaires. Mean PM2.5 were not significantly different between measurements (36.34 mu g/m(3) vs. 54.38 mu g/m(3), p = 0.60) but exceeded the WHO air quality guidelines. Mean and maximal CO levels were below the WHO cut-offs (0.56 ppm vs. 0.34 ppm, p = 0.414 and 26.1 ppm vs. 9.72 ppm, p = 0.007, respectively). In total, 90.6% of households were using wood stoves or fireplaces for heating, but half also owned clean fuel devices. The differences between devices that were owned versus those that were used were attributed to financial reasons. In both cases, the most frequent respiratory symptoms were phlegm (27.3% vs. 15.2%; p = 0.34) and cough (24.2% vs. 12.1%; p = 0.22). Our findings demonstrate the magnitude of HAP and confirm the return to harmful practices during Greece's austerity. Upon validation, these results can support strategies for fighting fuel poverty, empowering communities and strengthening local health systems.Prevention, Population and Disease management (PrePoD)Public Health and primary car

The UK's Global Health Respiratory Network: Improving respiratory health of the world's poorest through research collaborations.

Respiratory disorders are responsible for considerable morbidity, health care utilisation, societal costs and approximately one in five deaths worldwide [1-4]. Yet, despite this substantial health and societal burden – which particularly affects the world’s poorest populations and as such is a major contributor to global health inequalities – respiratory disorders have historically not received the policy priority they warrant. For example, despite causing an estimated 1000 deaths per day, less than half of the world’s countries collect data on asthma prevalence (http://www.globalasthmareport.org/). This is true for both communicable and non-communicable respiratory disorders, many of which are either amenable to treatment or preventable

Lung cancer and tobacco smoking in Crete, Greece: reflections from a population-based cancer registry from 1992 to 2013

Introduction The Cancer Registry of Crete is a regional population database that collects cancer morbidity/mortality data along with several risk factors. The current study assessed the geographical variation of lung cancer among ever and never smokers in Crete during the last 20 years. Material and Methods Lung cancer patient records (1992–2013) including information on medical history and smoking habits were obtained from the Cancer Registry of Crete. Age-Adjusted Incidence Rates (AAIR), prevalence of smoking among lung cancer patients and the Population-Attributable Fraction (PAF%) of tobacco smoking were estimated. Kaplan-Meier curves, grouped per smoking status were constructed, and spatio-temporal analyses were carried out to assess the geographical variations of lung cancer and smoking (a = 0.05). Results New lung cancer cases in Crete accounted for 9% of all cancers (AAIRboth genders = 40.2/100,000/year, AAIRmales = 73.1/100,000/year, AAIRfemales = 11.8/100,000/year). Ever smokers presented significantly higher incidence compared to ex-smokers (p = 0.02) and never smokers (p < 0.001). The highest increase was observed in ever smokers (AAIR1992 = 19.2/100,000/year, AAIR2013 = 25.4/100,000/year, p = 0.03), while never smokers presented the lowest increase from 1992 to 2013 (AAIR1992 = 5.3/100,000/year, AAIR2013 = 6.8/100,000/year, p = 0.2). The PAF% of lung cancer mortality is 86% for both genders (males: 89%, females: 78%). AAIRs ranged from 25 to 50/100,000/year, while significant geographical differences were observed among the municipalities of Crete (p = 0.02). Smokers living in the south-east urban regions presented higher risk of dying from lung cancer (RR = 2.2; 95%CI = 1.3–3.5). Conclusions The constant increase of lung cancer rates among both genders, especially in females, outlines the need for targeted, geographically-oriented, life-style preventive measures. Design of population-based screening programs, tobacco awareness campaigns and smoking cessation programs in lung cancer hot spots could be guide by these findings

Meta-KANSEI modeling with Valence-Arousal fMRI dataset of brain

Background: Traditional KANSEI methodology is an important tool in the field of psychology to comprehend the concepts and meanings; it mainly focusses on semantic differential methods. Valence-Arousal is regarded as a reflection of the KANSEI adjectives, which is the core concept in the theory of effective dimensions for brain recognition. From previous studies, it has been found that brain fMRI datasets can contain significant information related to Valence and Arousal. Methods: In this current work, a Valence-Arousal based meta-KANSEI modeling method is proposed to improve the traditional KANSEI presentation. Functional Magnetic Resonance Imaging (fMRI) was used to acquire the response dataset of Valence-Arousal of the brain in the amygdala and orbital frontal cortex respectively. In order to validate the feasibility of the proposed modeling method, the dataset was processed under dimension reduction by using Kernel Density Estimation (KDE) based segmentation and Mean Shift (MS) clustering. Furthermore, Affective Norm English Words (ANEW) by IAPS (International Affective Picture System) were used for comparison and analysis. The data sets from fMRI and ANEW under four KANSEI adjectives of angry, happy, sad and pleasant were processed by the Fuzzy C-Means (FCM) algorithm. Finally, a defined distance based on similarity computing was adopted for these two data sets. Results: The results illustrate that the proposed model is feasible and has better stability per the normal distribution plotting of the distance. The effectiveness of the experimental methods proposed in the current work was higher than in the literature. Conclusions: mean shift can be used to cluster and central points based meta-KANSEI model combining with the advantages of a variety of existing intelligent processing methods are expected to shift the KANSEI Engineering (KE) research into the medical imaging field

Effects and acceptability of implementing improved cookstoves and heaters to reduce household air pollution: a FRESH AIR study

The objective was to evaluate the effectiveness and acceptability of locally tailored implementation of improved cookstoves/heaters in low- and middle-income countries. This interventional implementation study among 649 adults and children living in rural communities in Uganda, Vietnam and Kyrgyzstan, was performed after situational analyses and awareness programmes. Outcomes included household air pollution (PM2.5 and CO), self-reported respiratory symptoms (with CCQ and MRC-breathlessness scale), chest infections, school absence and intervention acceptability. Measurements were conducted at baseline, 2 and 6-12 months after implementing improved cookstoves/heaters. Mean PM2.5 values decrease by 31% (to 95.1 µg/m3) in Uganda (95%CI 71.5-126.6), by 32% (to 31.1 µg/m3) in Vietnam (95%CI 24.5-39.5) and by 65% (to 32.4 µg/m3) in Kyrgyzstan (95%CI 25.7-40.8), but all remain above the WHO guidelines. CO-levels remain below the WHO guidelines. After intervention, symptoms and infections diminish significantly in Uganda and Kyrgyzstan, and to a smaller extent in Vietnam. Quantitative assessment indicates high acceptance of the new cookstoves/heaters. In conclusion, locally tailored implementation of improved cookstoves/heaters is acceptable and has considerable effects on respiratory symptoms and indoor pollution, yet mean PM2.5 levels remain above WHO recommendations.European Union’s Horizon 2020 programme under grant agreement no. 680997, TRIAL ID NTR5759, http://www.trialregister.nl/trialreg/admin/rctsearch.asp?Term=23332.

COPD’s early origins in low-and-middle income countries: what are the implications of a false start?

[Excerpt] The Global Initiative for chronic Obstructive Lung disease (GOLD)guideline of 2018 describes COPD as‘the result of a complexinterplay of long-term cumulative exposure to noxious gases andparticles, combined with a variety of host factors includinggenetics, airway hyper-responsiveness and poor lung growthduring childhood’.1Tobacco smoking is traditionally viewed as themain contributing factor to the development of COPD. However,COPD also occurs among non-smokers, especially in low-incomeand middle-income countries (LMICs).2,3Notably, more than 90%of COPD-related deaths occur in LMICs.4For these countries, otherrisk factors, such as ambient, occupational and household airpollution play a significant role in the development of COPD.1,2,5–7Does COPD in these settings have a different pathophysiologicaltrajectory compared to COPD in high-income countries, and if so:what does this imply?In normal lung development, airway branching is completed bythe 17th week of gestation, after which airways increase in volumeuntil young adulthood. Alveoli are present at birth and developfurther during childhood. Lung volume and airflow continue toincrease as the thorax grows, influenced by age, sex, and ethnicity,reaching a peak at young adulthood. Lung function then remainsconstant for about 10 years (the plateau phase), after which itgradually declines.8In the‘classic’COPD patient, the decline inlung function is more rapid than in healthy individuals. However,in a considerable proportion of COPD patients, lung function doesnot decline rapidly, but reaches a lower plateau phase in earlyadulthood instead. For these patients, a completely differentpathophysiological trajectory seems to lead to the diagnosis ofCOPD: the decline in lung function follows a normal pattern, yetthey seem to have a‘false start’by attaining a lower maximumlung function.

Screening for Depression in Cardiovascular Patients in Albania: Findings from the Country Check-Up Program

This is a retrospective study conducted in Vlora from January 2016 to April 2017 and the aim was to report the prevalence of depression in cardiovascular (CVD) patients. Depression assessment was done using the Patient Health Questionnaire (PHQ)-9 (PHQ-9). Data were derived from the patient records and the standard recommended cut-off point of PHQ-9 ≥ 10 was used. In total, data of 300 patients were analyzed. Depressive symptoms (PHQ-9 ≥ 10) were observed at 6% of the participants. Trouble falling asleep or staying asleep or sleeping too much, feeling tired or having little energy and having little interest or pleasure in doing things were the most common symptoms reported. In multivariate analysis, only family status showed statistical significance. Unmarried (mean rank = 207.22) are more likely to have moderate or severe depression level (OR 3.529; C.I. 95% 1.017–12.238). Future research should focus on the needed actions after depression screening (i.e. referral, treatment etc.). © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature

This systematic review aimed to bring together the best methods used to teach EBP to health professionals. The authors conducted a systematic search for the period 2005&ndash;2015 (an update of the search took place in October 2016) using PubMed interface (Medline). MeSH terms as well as free-text keywords were used. Studies were analyzed and evaluated by title and abstract. Those studies which fulfilled the inclusion criteria were assessed by full text. References of articles were also taken into consideration for identifying relevant studies not found through algorithm search. Twenty articles were found to be relevant. The majority of the studies were conducted among nurses (n=7) and physicians (n=6), and only a few among professionals from mixed disciplines (n=5). Two studies were conducted among chiropractors (n=1) and faculty members from a naturopathic and classical Chinese medicine institution (n=1). Researchers used a variety of different approaches, which varied with respect to duration and organization. We divided interventions into two categories. Single interventions included either a workshop, or a journal club, or a conference, or a lecture, or online learning tools, whereas multiple interventions included a combination of these approaches. An increase in EBP competencies and attitudes was reported in nine studies. Teaching methods for optimizing EBP among health professionals could become a robust standardized procedure of the medical educational curricula and lifelong learning of health care professionals.
