Biotechnology product development, biosafety regulation and environmental risk assessment in the Philippines
This study looks at the current biotechnology and biosafety situation in the Philippines. It assesses whether the country's biotechnology organizations are in a position to effectively perform biosafety regulation, protect intellectual property rights and respond to the accelerating pace of international biotechnology product development. Based on a mixture of primary and secondary information, the study finds that biotechnology development is constrained by funding and resources. It also finds that, while biosafety guidelines and practices are relatively strong, there are a number of institutional weaknesses. The study recommends measures to make biotechnology research and development more cost-effective and to improve biosafety in the country. Overall, the report calls for the Philippines to carefully balance the need for biotechnology regulation with the need for innovative biotechnology development
Prevalence of chronic cough, its risk factors and population attributable risk in the Burden of Obstructive Lung Disease (BOLD) study: a multinational cross-sectional study
Background: Chronic cough is a common respiratory symptom with an impact on daily activities and quality of life. Global prevalence data are scarce and derive mainly from European and Asian countries and studies with outcomes other than chronic cough. In this study, we aimed to estimate the prevalence of chronic cough across a large number of study sites as well as to identify its main risk factors using a standardized protocol and definition. Methods: We analyzed cross-sectional data from 33,983 adults (≥40 years), recruited between Jan 2, 2003 and Dec 26, 2016, in 41 sites (34 countries) from the Burden of Obstructive Lung Disease (BOLD) study. We estimated the prevalence of chronic cough for each site accounting for sampling design. To identify risk factors, we conducted multivariable logistic regression analysis within each site and then pooled estimates using random-effects meta-analysis. We also calculated the population-attributable risk (PAR) associated with each of the identified risk factors. Findings: The prevalence of chronic cough varied from 3% in India (rural Pune) to 24% in the United States of America (Lexington, KY). Chronic cough was more common among females, both current and passive smokers, those working in a dusty job, those with a history of tuberculosis, those who were obese, those with a low level of education, and those with hypertension or airflow limitation. The most influential risk factors were current smoking and working in a dusty job. Interpretation: Our findings suggested that the prevalence of chronic cough varies widely across sites in different world regions. Cigarette smoking and exposure to dust in the workplace are its major risk factors.info:eu-repo/semantics/publishedVersio
Association of respiratory symptoms and lung function with occupation in the multinational Burden of Obstructive Lung Disease (BOLD) study
Background
Chronic obstructive pulmonary disease has been associated with exposures in the workplace. We aimed to assess the association of respiratory symptoms and lung function with occupation in the Burden of Obstructive Lung Disease study.
Methods
We analysed cross-sectional data from 28 823 adults (≥40 years) in 34 countries. We considered 11 occupations and grouped them by likelihood of exposure to organic dusts, inorganic dusts and fumes. The association of chronic cough, chronic phlegm, wheeze, dyspnoea, forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1)/FVC with occupation was assessed, per study site, using multivariable regression. These estimates were then meta-analysed. Sensitivity analyses explored differences between sexes and gross national income.
Results
Overall, working in settings with potentially high exposure to dusts or fumes was associated with respiratory symptoms but not lung function differences. The most common occupation was farming. Compared to people not working in any of the 11 considered occupations, those who were farmers for ≥20 years were more likely to have chronic cough (OR 1.52, 95% CI 1.19–1.94), wheeze (OR 1.37, 95% CI 1.16–1.63) and dyspnoea (OR 1.83, 95% CI 1.53–2.20), but not lower FVC (β=0.02 L, 95% CI −0.02–0.06 L) or lower FEV1/FVC (β=0.04%, 95% CI −0.49–0.58%). Some findings differed by sex and gross national income.
Conclusion
At a population level, the occupational exposures considered in this study do not appear to be major determinants of differences in lung function, although they are associated with more respiratory symptoms. Because not all work settings were included in this study, respiratory surveillance should still be encouraged among high-risk dusty and fume job workers, especially in low- and middle-income countries.publishedVersio

Cohort Profile: Burden of Obstructive Lung Disease (BOLD) study
The Burden of Obstructive Lung Disease (BOLD) study was established to assess the prevalence of chronic airflow obstruction, a key characteristic of chronic obstructive pulmonary disease, and its risk factors in adults (≥40 years) from general populations across the world.
The baseline study was conducted between 2003 and 2016, in 41 sites across Africa, Asia, Europe, North America, the Caribbean and Oceania, and collected high-quality pre- and post-bronchodilator spirometry from 28 828 participants.
The follow-up study was conducted between 2019 and 2021, in 18 sites across Africa, Asia, Europe and the Caribbean. At baseline, there were in these sites 12 502 participants with high-quality spirometry. A total of 6452 were followed up, with 5936 completing the study core questionnaire. Of these, 4044 also provided high-quality pre- and post-bronchodilator spirometry.
On both occasions, the core questionnaire covered information on respiratory symptoms, doctor diagnoses, health care use, medication use and ealth status, as well as potential risk factors. Information on occupation, environmental exposures and diet was also collected
Assessment of agribusiness venture arrangements and sugarcane block farming for the modernization of agriculture
After completion of their land reform program, countries such as Japan, South Korea, and Taiwan implemented land consolidation to effect economies of scale specifically in the adoption of modern technologies. Land consolidation plans included the physical reallocation of parcels, joint farming through land exchanges and sale, temporary quasi-land acquisition, and land renovation. In the Philippines, land consolidation to improve farm productivity and income was pursued through Agribusiness Venture Arrangements (AVAs) and the Sugarcane Block Farming (SBF). The objective of this study is to assess the performance of AVAs and SBF in increasing farm productivity and income in the agrarian sector. The case study approach was used focusing on three export crops, namely, banana, pineapple, and sugarcane which were selected based on their significant contribution to the Philippines' export earnings as well as to gross value added of agriculture. The study notes several issues on production and capital investments, marketing and pricing, institutional support, and contract terms that affect the implementation of AVAs and SBF. It recommends that AVAs, SBF arrangements should be encouraged, but government has to provide a policy environment for Philippine exports crops to be competitive. Agrarian reform beneficiaries and their associations should also be supported through capacity-building activities and access to legal advice
Making Biotechnology Safer: An Assessment from the Philippines
Modern biotechnology is one of the most controversial areas of scientific development. It has been championed as a solution to poverty, hunger and environmental degradation. However, there are also many environmental, health and social equity concerns associated with the genetic modification of crops and animals. The challenge, particularly for developing countries, is to benefit from these technologies while ensuring that biosafety issues are adequately addressed.Biotechnology, Philippines

Overdiagnosis of COPD in subjects with unobstructed spirometry
Background: There are several reports on the underdiagnosis of COPD, while little is known about COPD overdiagnosis and overtreatment. We describe the overdiagnosis and the prevalence of spirometrically defined false-positive COPD, as well as their relationship with overtreatment across 23 population samples in 20 countries participating in the BOLD Study between 2003 and 2012. Methods: A false-positive diagnosis of COPD was considered when participants reported a doctor's diagnosis of COPD, but postbronchodilator spirometry was unobstructed (FEV1/FVC > LLN). Additional analyses were performed using the fixed ratio criterion (FEV1/FVC < 0.7). Results: Among 16,177 participants, 919 (5.7%) reported a previous medical diagnosis of COPD. Postbronchodilator spirometry was unobstructed in 569 subjects (61.9%): false-positive COPD. A similar rate of overdiagnosis was seen when using the fixed ratio criterion (55.3%). In a subgroup analysis excluding participants who reported a diagnosis of "chronic bronchitis" or "emphysema" (n = 220), 37.7% had no airflow limitation. The site-specific prevalence of false-positive COPD varied greatly, from 1.9% in low- to middle-income countries to 4.9% in high-income countries. In multivariate analysis, overdiagnosis was more common among women, and was associated with higher education; former and current smoking; the presence of wheeze, cough, and phlegm; and concomitant medical diagnosis of asthma or heart disease. Among the subjects with false-positive COPD, 45.7% reported current use of respiratory medication. Excluding patients with reported asthma, 34.4% of those with normal spirometry still used a respiratory medication. Conclusions: False-positive COPD is frequent. This might expose nonobstructed subjects to possible adverse effects of respiratory medication.info:eu-repo/semantics/publishedVersio
