    BACKGROUND: Migraine is a common and distressing neurological condition characterised by recurrent throbbing headaches, nausea and heightened sensitivity to light and sound. Accumulating evidence suggests that cerebral arteries dilate during migraine, causing distal microvessels to constrict, which could activate nociceptors and cause onset of headache pain. If so, preventing or attenuating chronic microvascular constriction, and promoting a dilatory phenotype, may reduce frequency and/or severity of migraines. The primary aim of the L-Arginine and Aged Garlic Extract (LARGE) trial is to investigate whether oral treatment with dietary nutraceuticals, L-arginine and aged garlic extract (AGE), both systemic vasodilatory agents, will alleviate migraine frequency, duration and severity in adults with chronic frequent episodic migraines.

    METHODS: The study is a randomised double-blind placebo-controlled phase-II single-site clinical trial conducted in Perth, Australia. The target sample is to recruit 240 participants diagnosed with chronic frequent episodic migraines between 18 and 80 years of age. Participants will be randomised to one of four treatment groups for 14 weeks (placebo induction for 2 weeks, followed by 12 weeks on one of the respective treatment arms): placebo, L-arginine, AGE, or a combination of L-arginine and AGE. The doses of L-arginine and AGE are 1.5 g and 1 g daily, respectively. The primary outcome is to assess migraine response using change in migraine frequency and intensity between baseline and 12 weeks. Secondary outcomes include the impact of L-arginine and/or AGE on photosensitivity, retinal vessel changes, and blood biomarker concentrations of vascular tone, following a 12-week intervention.

    DISCUSSION: The protocol describes the oral administration of 2 nutraceutical-based interventions as possible prophylactic treatments for chronic frequent episodic migraines, with potential for direct clinical translation of outcomes. Potential limitations of the study include the fixed-dose design of each treatment arm and that in vivo neuroimaging methods, such as magnetic resonance imaging (MRI), will not be conducted to determine putative cerebro-vasodilatory changes to coincide with the outcome measures. Dose-response studies may be indicated.

    TRIAL REGISTRATION: The trial was retrospectively registered with the Australian New Zealand Clinical Trials Registry ACTRN12621001476820 (Universal Trial Number: U1111-1268-1117) on 04/08/2021. This is protocol version 1, submitted on 25/11/2022.

    Persimmon (Diospyros kaki Thunb.) is widely cultivated in China. On October 15, 2019, about 10% of persimmon fruits showed fruit rot in the orchards of Guilin, Guangxi, China (24°45' N, 110°24' E), which could cause more than 15% of yield losses. The initial symptoms of fruit rot exhibited irregular brown to black spots (range from 2 to 4 cm in diameter), the areas surrounding the blackened spots would be soft and rotten, and three diseased fruit samples were collected from three orchards, respectively. Tissues (5×5 mm) were cut from infected margins, surface-disinfected in 75% ethanol for 10 s, 2% NaClO for 2 min, rinsed three times in sterilized distilled water, and incubated on potato dextrose agar (PDA) at 25°C under 12/12 h light/darkness for a week. Forty-one tissues yielded morphologically similar cultures, and three representative isolates LPG1-1, LPG1-2, and YSG-1 were selected from three samples for further study, respectively. Their colonies showed wavy edges, white surfaces, and dense aerial hyphae on PDA after two weeks. Conidia were fusiform, straight to slightly curved, and 4-septate; basal cells were conical, hyaline, thin, and verruculose with two or three long and hyaline apical appendages and one short apical appendage; three median cells of LPG1-1 with length 14.06 to 17.69 μm (n=100), and LPG1-2 with length 14.03 to 17.61 μm (n=100) were dark brown to olivaceous, while three median cells of YSG-1 with length 12.54 to 15.58 μm (n=100) were dark brown. The conidial sizes of LPG1-1, LPG1-2, and YSG-1 were 17.41 to 27.68 × 4.63 to 8.55 μm (n=100), 18.06 to 27.41 × 4.33 to 8.21 μm (n=100), and 16.58 to 27.73 × 4.99 to 8.39 μm (n=100), respectively. The morphological characteristics were consistent with Neopestalotiopsis spp. (Maharachchikumbura et al. 2012; Maharachchikumbura et al. 2014). Primer pairs ITS4/ITS5, BT2a/BT2b, and EF1-526F/EF-1567R were used to amplify internal transcribed spacer (ITS), beta-tubulin (TUB2), and translation elongation factor 1 alpha (TEF1-α), respectively (Shu et al., 2020). All DNA fragments were sequenced by Sangon Biotech Co., Ltd. (Shanghai, China). Sequences have been deposited in GenBank (ITS: OM349120 to OM349122, TUB2: OM688188 to OM688190, TEF1-α: OM688191 to OM688193). Based on BLASTn analysis of ITS, TUB2, and TEF1-α sequences, the LPG1-1 and LPG1-2 showed over 99% similarity to N. saprophytica, and YSG-1 showed over 99% similarity to N. ellipsospora. Phylogenetic analysis of the three isolates was performed with MEGA10 (version 10.0) based on sequences of ITS, TUB2, and TEF1-α using maximum parsimony analysis. The results revealed that LPG1-1 and LPG1-2 were clustered with N. saprophytica, and YSG-1 was clustered with N. ellipsospora. Pathogenicity tests of three isolates were conducted on 72 healthy persimmon fruits with and without wounds, and 9 fruits are for each treatment. The wound was made by a sterilized needle. Fruits were pre-processed with 75% ethanol for 10 s, 1% NaClO for 2 min and rinsed three times in sterile water. Conidial suspensions (10 µL, 106 conidia/mL in 0.1% sterile Tween 20) were inoculated on each site (4 sites/fruit). Control group was treated with 0.1% sterile Tween 20. All inoculated sites were covered with wet cotton. The inoculated fruits were placed in a plastic box to maintain humidity at 28℃. After 5 days, all wounded fruits showed fruit rot, whereas unwounded and control fruits remained asymptomatic, there were significant differences (P<0.05) in aggressiveness between N. saprophytica (average lesion diameter 13.1 mm) and N. ellipsospora (average lesion diameter 14.9 mm). Koch's postulates were fulfilled by re-isolating the causal agents from inoculated fruits. N. ellipsospora was previously reported as an endophyte in D. montana in southern India (Reddy et al. 2016). N. saprophytica could cause leaf spot of Erythropalum scandens and Magnolia sp., and fruit rot of Litsea rotundifolia in China and leaf spot of Elaeis guineensis in Malaysia (Yang et al. 2021, Ismail et al. 2017). To our knowledge, this is the first report of N. ellipsospora and N. saprophytica causing fruit rot on persimmon in the world. The results will provide a foundation for controlling fruit rot caused by pestalotioid fungi on persimmon.

    PURPOSE: This study evaluated the clinical and biochemical safety profile of infiltration of lidocaine with adrenaline in wide-awake local anesthesia no tourniquet for distal radius plating.

    METHODS: Twenty-four participants were randomly assigned to the therapeutic group (n = 19) (1% lidocaine in 1:100,000 adrenaline) and control group (n = 5) (2% lidocaine alone). Clinical parameters, including skin necrosis, duration of recovery of sensation, and lidocaine toxicity, were monitored. The serum lidocaine level was measured at different time intervals using a high-performance liquid chromatography reagent.

    RESULTS: No lidocaine toxicity was recorded in any participant. The therapeutic group had a longer time for recovery of sensation. There was a significant difference in the serum lidocaine levels between both the groups at all time intervals up to 6 hours, with all participants exhibiting serum lidocaine levels below the mild toxicity level of 6.0 μg/mL.

    CONCLUSIONS: Lidocaine used within a safe recommended dose in wide-awake local anesthesia no tourniquet for distal radius plating is clinically and biochemically safe.

    CLINICAL RELEVANCE: Determining the clinical and biochemical safety profile of lidocaine with adrenaline in wide-awake local anesthesia no tourniquet can promote wider use of this technique.

    OBJECTIVE: Tuberculosis (TB) is an old disease and it has infected millions of people worldwide. Since it is a highly infectious disease, many people became TB contact due to prolonged exposure to a person with TB infection. This group of people is at a higher risk of getting latent and active TB infection, hence a vulnerable group for active TB screening. This study explored the factors that determined the attitude score, the level of knowledge, attitude, and stigma (KAS) regarding TB disease among TB contact.

    METHODS: This cross-sectional study used a validated KAS questionnaire, performed among 338 TB contacts from 5 health clinics in Kedah, Malaysia. The respondents were selected via convenience sampling. Simple and multiple linear regressions were used to analyze the data.

    RESULTS: The mean KAS scores of participants are 73.5% [standard deviation (SD)=17.06], 83.0% (SD=10.33), and 67.0% (SD=16.72), respectively. Higher income (p=0.001), better knowledge score (p<0.001), and higher stigma score (p=0.003) are the significant associated factors for the attitude score.

    CONCLUSIONS: This study revealed that most of the TB contacts have good knowledge and constructive attitude toward TB prevention and screening, but their level of stigma on TB is high. The implementation of TB education and intervention programs among TB contacts are required especially among low-income groups.

    OBJECTIVE: Primary myelofibrosis is a rare type of myeloproliferative neoplasm with an annual incidence rate of 0.47 per 100,000. A retrospective, observational study was conducted to determine the disease evolution and costs of treatment for myelofibrosis (MF) patients managed in 4 Ministry of Health (MOH) hospitals in Sarawak, Malaysia.

    METHODS: The estimation of treatment cost was a planned analysis of the Real World Evidence (RWE) study which included retrospective chart review of adult MF patients treated in Sarawak General, Sibu, Bintulu and Miri Hospitals. The study was approved by Sarawak General Hospital HRRC and MREC. The current study was conducted to estimate the cost of out-patient visits, hospitalisation, transfusion and medication from the perspective of MOH. Out-patient visits and hospitalisation costs were calculated using current unit costs for full fee-paying charges of MOH hospitals. Transfusion costs were estimated for packed cell and platelet transfusions. Medication costs were calculated using drug prices from IQVIA database for MOH hospital sub-sector in 2021. Unit costs were standardised to index year of 2021.

    RESULT: Data from 63 patients was available for analysis. Mean annual health resource utilisation (HRU) was 6.13 clinic visits, 9.47 days of hospitalisation and 1.61 transfusions per patient per year. Mean HRU cost was RM23,320 (USD5,217) per patient per year, comprised of RM19,122 (USD4,278) in drug costs, RM3,030 (USD678) for hospitalisation, RM799 (USD178) for transfusions and RM368 (USD82) for outpatient cost.

    CONCLUSION: The present analysis suggests that medication and hospitalisation were the main drivers of costs for MF treatment in Sarawak MOH hospitals. This study provides the first RWE estimate of the cost of MF in Malaysia and may provide insight into unmet clinical needs and a guide for further health economic research into the treatment of MF.

    BACKGROUND: Fatigue is a typical consequence of cancer that can affect one's quality of life (QOL). The goal of this review is to provide comprehensive data on the impact of fatigue on QOL of cancer patients.

    METHODS: An electronic data search in Web of Science, SCOPUS, and PubMed for relevant papers; those written in English; those reporting quantitative data; and those including more than one hundred patients who received just chemotherapy were included. Studies involving participants that received other kinds of anti-neoplastic therapies were excluded.

    RESULTS: A total of 35 papers published between January 2000 and December 2021 were retrieved from the search databases of which (11612 patients) met the inclusion criteria. Findings showed that fatigue negatively affected QOL with a pooled prevalence of 49% (95% CI; 25.00-74.00) and the significant heterogeneity between articles was (I²=98%, P <0.001). Further, breast cancer contributed to the majority of selected articles with about 55 % (95%CI; 9:00- 94:00), followed by cancer (unspecified) 44% (95%CI; 5:00 - 92:00). Most studies (71%) (95%CI; 4:00 - 99:00) used the brief fatigue inventory (BFI) tool to assess severity of fatigue and 39% (95%CI; 17:00 -68:00) employed the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire to evaluate QOL among cancer survivors.

    CONCLUSION: The prevalence of fatigue in cancer patients is high and fatigue has a negative impact on QOL of cancer patients receiving chemotherapy. Directionality, fatigue needs to be addressed and treated properly for better improvement of health status and QOL in cancer patients.

    BACKGROUND: Antimicrobial resistance is an important global problem resulting in an improper response of infections to antimicrobials and an increase in the duration and cost of treatment. Healthcare professionals play an important role in addressing Antimicrobial resistance and positive perception is important for involvement in antimicrobial stewardship policies. Hence the perception of key Healthcare professionals, including physicians, nurses, and hospital pharmacists, towards Antimicrobial resistance antimicrobial stewardship policies was studied.

    METHODS: A cross-sectional study was conducted in a tertiary care hospital at Lalitpur, from January to March 2021 using stratified random sampling. An online questionnaire was circulated to the selected Healthcare professionals. Median Antimicrobial resistance and antimicrobial stewardship policy scores were calculated and compared among different subgroups. Previous engagement with Antimicrobial resistance and antimicrobial stewardship policies programs was also noted. Descriptive statistics, Mann Whitney, and Kruskal Wallis tests were used for data analysis.

    RESULTS: The response rate was 89.3% (202/226). Antimicrobial resistance was regarded as a serious problem in the Nepali community by participants with work experience of 1-5 years, 87 (75.6%, p=0.029), and female participants, 62 (45.5%, p<0.001). Most physicians, females, and participants with working experience 1-5 years believed inappropriate use of antibiotics can harm patients and is professionally unethical. Physicians supported the availability of local antimicrobial guidelines and protocols. The median scores for Antimicrobial resistance (p<0.001) and Antimicrobial resistance eradication (p=0.048) differed according to age groups.

    CONCLUSIONS: Healthcare professionals believed Antimicrobial resistance was an important issue. Antibiotic guidelines developed should be strictly implemented. Healthcare professionals also believed inappropriate use of antibiotics can harm patients and is professionally unethical.

    Congenital knee dislocation (CKD) is a rare malformation characterized by hyperextension deformity of the knee with anterior tibia displacement, present at birth. Rarely reported, CKD might occur as an isolated deformity or commonly associated with musculoskeletal abnormalities, with the most common ones being developmental dysplasia of the hip (DDH) and clubfoot. The etiology is unknown, but CKD has been associated with certain intrinsic and extrinsic factors. Treatment with conservative methods at an early stage is most likely to yield successful results. We report here a rare case of successful spontaneous reduction of CKD in an infant within 24 hours of life.

    BACKGROUND: Diastasis rectus abdominis (DRA) involves the separation of the midline abdominal muscles and linea alba and affects more than half of postpartum women. This study aimed to assess the effect of a split tummy exercise program (STEP) on DRA closure in postpartum mothers.

    METHODS: A randomized controlled trial was conducted from 2008 to 2020 at the Obstetrics and Gynaecology Clinic of the Universiti Kebangsaan Malaysia Medical Centre. Primigravida mothers diagnosed with DRA were selected and randomly assigned to the intervention (n=21) or control (n=20) group. The intervention group underwent a home-based STEP consisting of three phases of nine abdominal exercises. DRA size was assessed at baseline and at 8 weeks postpartum using two-dimensional ultrasound.

    RESULTS: The mean age of the participants was 28 years (standard deviation, 3.6), with the majority of Malay ethnicity (87.8%) and working mothers (78%). After 8 weeks, the intervention group showed a significant reduction in DRA size of up to 27% (mean difference, 6.17 mm; 95% confidence interval, 3.7-8.7; P<0.001). No significant intergroup DRA changes were observed after 8 weeks of follow-up.

    CONCLUSION: Early postpartum screening for DRA should be advocated to allow early STEP intervention to ensure favorable outcomes. STEP intervention is an effective postnatal training program for managing DRA.

    While subclinical hypothyroidism (SCH) was reportedly associated with an increased risk of cardiovascular mortality, the relationship between SCH and clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) is uncertain. The aim of this study was to assess the association of SCH and cardiovascular outcomes in patients undergoing PCI. We searched PubMed, Embase, Scopus, and CENTRAL databases from its inception until April 1, 2022 for studies comparing the outcomes between SCH and euthyroid patients undergoing PCI. Outcomes of interest include cardiovascular mortality, all-cause mortality, myocardial infarction (MI), major adverse cardiovascular and cerebrovascular events (MACCE), repeat revascularization and heart failure. Outcomes were pooled using the DerSimonian and Laird random-effects model and reported as risk ratios (RR) and 95% confidence intervals (CI). A total of 7 studies involving 1132 patients with SCH and 11,753 euthyroid patients were included in the analysis. Compared with euthyroid patients, patients with SCH had significantly higher risk of cardiovascular mortality (RR 2.16, 95% CI: 1.38-3.38, P < 0.001), all-cause mortality (RR 1.68, 95% CI: 1.23-2.29, P = 0.001) and repeat revascularization (RR 1.96, 95% CI: 1.08-3.58, P = 0.03). However, there were no differences between both groups in terms of incidence of MI (RR 1.81, 95% CI: 0.97-3.37, P = 0.06), MACCE (RR 2.24, 95% CI: 0.55-9.08, P = 0.26) and heart failure (RR 5.38, 95% CI: 0.28-102.35, P = 0.26). Our analysis suggests among patients undergoing PCI, SCH was associated with increased risk of cardiovascular mortality, all-cause mortality and repeat revascularization compared to euthyroid patients.

    China's construction industry confronts with the dilemma of carbon emissions in adjusting the environmental regulations. Many studies are neglected on discovering the potential nexus amongst environmental regulations (ERs), technological innovation (TI) and CEI (CEI) and ignores the relationships amongst TI for reducing CEI. To mitigate this gap, this study bridges institutional theory to integrate the practices in the construction industry. This study applies a panel dataset on the construction industry from 30 provinces during 2004-2018 and uses it with a two-step system-generalised method of moments for analysis. The proposed method enables the prevention of the interference of the heteroscedasticity problem and improves certain analytical efficiency. The results are as a guideline for policymakers in rechecking the policies and regulations adequacy. The findings indicate that (1) the forced emission reduction effect is proven by command-and-control and market-based ERs, which can inhibit CEI; (2) voluntary ERs have an inverted U-shaped nexus with CEI; in other words, the green paradox effect shifts to the forced emission reduction effect once the intensity of voluntary ERs increases; and (3) market-based and voluntary ERs reduce CEI effectively by using TI as the mediator in construction industry.

    The present study was to determine optimum conditions for gelatin extraction from the skin of buffalo (Bubalus bubalis) using response surface methodology. A central composite design (CCD) was performed to evaluate the effects of NaOH concentration ( X 1 ), pre-treatment time ( X 2 ), extraction temperature ( X 3 ), and extraction time ( X 4 ) on the yield (Y 1), gel strength (Y 2), and hydroxyproline content (Y 3) of the extracted gelatin. The optimal combination of the independent variables for a good gelatin yield with high gel strength and hydroxyproline content was found at X 1 (0.77 M), X 2 (5.08 h), X 3 (62.93 °C) and X 4 (11.62 h). The experimental values for Y 1 (16.91%), Y 2 (236.5 g), and Y 3 (41.4 g/100 g) were in good agreement with the predicted values of 17.87% yield, 237.80 g gel strength and 41.90 g/100 g of hydroxyproline content. Extraction temperature and extraction time were observed to be the most important factors that influenced the yield, gel strength, and hydroxyproline content, meanwhile pre-treatment time showed negative correlations with the yield and hydroxyproline content of the extracted gelatin. This study demonstrated that manipulation of specific parameters could improve extraction efficiency without compromising the quality of buffalo gelatin, thereby promoting it as an alternative source for gelatin production.

    Tobacco farming in Bangladesh has significant and far-reaching environmental impacts, affecting the land, water, and air. While the country has implemented tobacco control measures, the lack of monitoring and enforcement has resulted in environmental degradation and public health concerns. This study aims to document the environmental impact of tobacco farming in Bangladesh, adopting a qualitative approach to collect and analyze data. The study used focus group discussions, key informant interviews, and a structured questionnaire survey to gather data, assessing the impact of tobacco farming on the environment, socioeconomic conditions, and human health using a five-point impact assessment scale. Results illustrated that tobacco cultivation contributes to the ecosystem and natural resource degradation, leading to a loss of habitat diversity and domestic animal death. Soil erosion, water pollution, and air pollution from excessive plowing and pesticide usage have also been observed, causing skin diseases and other health issues. Despite some economic benefits, social conditions have worsened due to drug addiction and conflicts among tobacco workers. The study will help policymakers and environmentalists by highlighting the need to take action in reducing the environmental and social impacts of tobacco farming in Bangladesh. It also informs the public about the potential tobacco production and consumption risks. This study provides important insights into the adverse effects of tobacco farming in Bangladesh and emphasizes the importance of implementing appropriate measures to reduce environmental and public health impacts.

    Fibre reinforced polymer (FRP) composite is a useful material. It has been utilised to enhance the structural behaviour of reinforced concrete beams (RCB). It is also crucial to summarise the impact of FRP on various types of RCB properties. This study summarises the FRP usage's impact on the RCB's structural behaviour based on previous research by reviewing and discussing the experimental study and finite element analysis (FEA) results. Based on previous relevant literature reviews, the experimental investigation and FEA showed significant improvements in flexure, stiffness, young modulus, load-deflection, ultimate load capacity, fracture pattern, and failure mode when FRP was used in RCB production. This FRP composite material can be used as the external reinforcement for RCB due to its high strength capability, force, load, and corrosion resistance with adhesive and anchorage properties. Using FRP in RCB can benefit civil engineering by increasing its structural behaviour and performance, especially in construction industry.

    Borophene has been recently reported to be a promising catalyst for water splitting. However, as a newly synthesized two-dimensional material, there are several issues that remain to be explored. In the present study, we investigate the catalytic performance of three kinds of pristine and decorated borophenes using first-principles calculations. Our calculations show that Ni-doped α borophene can be a highly active catalyst for water splitting. Doping or decorating with different transition metals such as Co or Ni at different sites shows a strong effect on the catalytic performance of α, β12 and χ3 borophenes. Ni-doped α borophene shows low Gibbs free energy of hydrogen adsorption (ΔG H ∼ 0.055 eV) for the hydrogen evolution reaction (HER) and promising overpotential (0.455 V) for the oxygen evolution reaction (OER).

    INTRODUCTION: Foxtail millet (Setaria italica L. beauv) is an important crop in underdeveloped countries; however, yield levels are low. The use of varied germplasm in a breeding approach is critical for increasing productivity. Foxtail millet can be cultivated effectively in a wide range of environmental circumstances but it is best suited to hot and dry climates.

    METHODS: In the current study, multivariant traits were used to define 50 genotypes in the first year and 10 genotypes in the second year. The phenotypic correlations among all traits in the entire germplasm were assessed, and the data acquired for all quantitative characters were subjected to analysis of variance for augmented block design. Furthermore, WINDOWS STAT statistical software was used to carry out a principal component analysis (PCA). The presence of substantial variations in most symptoms was shown by analysis of variance.

    RESULTS: Genotypic coefficient of variation (GCV) projections for grain yields were the highest, followed by panicle lengths and biological yields. Plant height and leaf length had the highest PCV estimates, followed by leaf width. Low GCV and phenotypic coefficient of variation (PCV) were measured as leaf length and 50% flowering in days. According to the PCV study, direct selection based on characters, panicle weight, test weight, and straw weight had a high and positive effect on grain yield per plant in both the rainy and summer seasons, indicating the true relationship between these characters and grain yield per plant, which aids indirect selection for these traits and thus improves grain yield per plant. Variability in foxtail millet germplasm enables plant breeders to effectively select appropriate donor lines for foxtail millet genetic improvement.

    DISCUSSION: Based on the average performance of genotypes considered superior in terms of grain yield components under Prayagraj agroclimatic conditions, the best five genotypes were: Kangni-7 (GS62), Kangni-1 (G5-14), Kangni-6 (GS-55), Kangni-5 (GS-389), and Kangni-4 (GS-368).

    BACKGROUND: Asthma is a chronic inflammatory disease of the airway characterized by respiratory symptoms: wheezing, shortness of breath, coughing, and chest tightness. Globally, asthma affects over 300 million individuals and carries high morbidity and mortality burden. Previous studies have estimated the prevalence of asthma; however, prevalence estimates have been changing over time. Here, in a population of young Chinese adults from Singapore, we aimed to obtain an updated prevalence of asthma and its phenotypes, and identify potential associated risk factors.

    METHODS: The Singapore/Malaysia Cross-Sectional Genetics Epidemiology Study (SMCGES) is an ongoing study which uses established ISAAC guidelines to collect epidemiological data and information pertaining to allergic diseases such as asthma. Responses from young Chinese adults recruited in the National University of Singapore were analyzed.

    RESULTS: Lifetime asthma prevalence rate was estimated at 19.1% (2049/10,736), while current asthma prevalence rate was estimated at 6.3% (679/10,736). For ever asthma, the most important risk factor was a parental history of asthma. Increased consumption of pulses (aOR: 0.822, 95% CI: 0.706-0.958) was associated with a lowered odds of ever asthma, but cereals (aOR: 1.256, 95% CI: 1.006-1.580), pasta (aOR: 1.265, 95% CI: 1.027-1.553), butter (aOR: 1.350, 95% CI: 1.113-1.632), and margarine (aOR: 1.343, 95% CI: 1.081-1.660) were associated with a higher risk of ever asthma. Increased television/computer usage was associated with a decreased risk of ever asthma (aOR: 0.448, 95% CI: 0.367-0.545). Conversely, genetic factors had a lower strength of effect on current asthma (parental history of asthma - OR: 1.465, 95% CI: 1.135-1.888) as compared to ever asthma. Only increased potato consumption was significantly associated with an increased risk of current asthma (most or all days per week vs never or only occasionally - aOR: 1.577, 95% CI: 1.145-2.180). Physical activity (aOR: 0.693, 95% CI: 0.542-0.885) was associated with a lower odds of asthma, while second-hand smoke exposure was associated with an increased risk for current asthma (aOR: 1.435, 95% CI: 1.001-2.047).

    CONCLUSION: Overall, the prevalence of lifetime asthma and current asthma among young Chinese adults was 19.1% and 6.3%, higher than that of previous studies. Our results suggested a stronger association between genetic factors and ever asthma as compared to current asthma. Parental asthma was the most important intrinsic epidemiological factor for asthma manifestation, while various foods, physical activity levels, and television or computer usage were also significantly associated with asthma. Future studies should consider risk factors in conjunction with other accompanying variables given the potential interactions between them, to discern the effects of environment and lifestyle on asthma more distinctly.
