Abstract Background: The factors that cause recurrent wheezing in children are complex, and premature delivery may be one of these factors. Little is known about early wheezing in preterm infants.Methods: Data were sourced from 1616 children born between 2007 and 2013 from 8 hospitals in Guangxi, China. All children were followed up by telephone or questionnaire through the sixth year of life. Children were grouped by gestational age (GA): Group A, GA ≤ 32 weeks; Group B, 32 weeks < GA < 37 weeks; and Group C, 37 weeks ≤ GA < 42 weeks.Results: The incidences and risk factors for early wheezing in preterm infants were analysed. The incidences of early wheezing were as follows: Group A > Group B > Group C. The incidence of persistent early wheezing in Group A or Group B was significantly higher than that in Group C, respectively. SGA (95% CI: 1.097 to 7.519) was a risk factor for early wheezing in group A. Male sex (95% CI: 1.595 to 4.501) and family history of allergies (95% CI: 1.207 to 3.352) were risk factors for early wheezing in group B.Conclusions: 1. New-borns with younger GAs had a higher risk of early wheezing. 2. The incidence of persistent early wheezing for preterm infants (GA ≤ 32 weeks and 32 weeks < GA < 37 weeks) was higher than that for full-term infants (37 weeks ≤ GA < 42 weeks). 3. SGA was a risk factor for early wheezing in preterm infants with a GA ≤ 32 weeks. 4. Male sex, personal history of allergies and family history of allergies were all possible factors affecting early wheezing in preterm infants with a GA > 32 weeks but < 37 weeks and full-term infants. Among them, male sex and family history of allergies were risk factors for early wheezing. 5. Mode of delivery, passive smoking, breastfeeding and invasive mechanical ventilation were not possible risk factors for early wheezing in infants of different GAs.

Abstract Background: The related factors that cause recurrent wheezing in children are complex, and premature delivery may be one of the reasons. Little is known about early wheezing in preterm infants. Methods: Data sourced from 1616 children born between 2007 and 2013 from 8 hospitals of Guangxi in China. All children were followed by telephone or questionnaire through the sixth year of life. Children were grouped by characters of age: Group A: gestational age (GA) ≤ 32 weeks, Group B: 32 weeks < GA < 37 weeks, Group C: 37 weeks ≤ GA < 42 weeks. Results: The incidence and the risk factors of early wheezing in preterm infants were analyzed. The incidence of early wheezing: Group A > Group B > Group C. In Group A, the proportion of small-for-gestational-age (SGA) infant was higher in early wheezing group than in normal group (P = 0.005). Male (95% CI: 1.611 to 4.601) and family history of allergy (95% CI: 1.222 to 3.411) were the risk factors for early wheezing in Group B. Conclusions: Newborns with younger GA had a higher risk of early wheezing. SGA was a possible factor influencing early wheezing in preterm infants with GA≤ 32 weeks. Male and family history of allergy were the risk factors for early wheezing in preterm infants with 32 weeks < GA < 37 weeks.

  Background: Asthma is a inflammatory condition of the lung airways resulting in episodic airflow obstruction. Symptoms are produced by irritation of small airways and may include bronchial hyper responsiveness, coughing, mainly at night or early morning. The mutable airflow obstruction is often adjustable, either spontaneously or by management . Objective: to find possible etiological risk factors and their links to Children asthma. Methods: This case-control study was conducted in four pediatric teaching hospitals for the period extending from 1st of April to end of November 2018. A total of 300 children > 15years were chosen randomly from the pediatric outpatient clinic, and divided in two group. Group A : one hundred fifty asthmatic patients were labeled as asthmatic . Group B : one hundred fifty children were matched to group A by age, sex, the group B without any history of asthma. Inclusion criteria for Group A were: Diagnosed as asthmatic by consultant pediatrician and should be respond well to anti asthmatic medication. Inclusion criteria for Group B were: Healthy or apparently healthy and without any history of medical problem or chronic diseases. Any child who is not accompanied by his /her mother or relative, and who didn't meet the selection criteria for the A and B groups will be excluded from the study . Results: After adjusting for possible cofounders; the study showed the factors which had significant association with childhood asthma were parent consanguinity 54%(P<0.001), low educational level of parents 63%, 58% (P<0.001), small house room 65% (P<0.001), presence of animals in the home57%(P<0.001), family history of asthma72% (P<0.001), , mother disease and medications 56%(P<0.001), household exposure 69% (P<0.001), respiratory infection during infant stage 81%(P<0.001) bottle feeding74%(P<0.001) . Conclusion: The independent risk factors after adjusting was were parent consanguinity, low educational level of parents, small house room, presence of animals in the home, family history of asthma, mother disease and drugs use through pregnancy, household exposure, recurrent respiratory infection during 1st year of life. Exclusive breast feeding (1st 6 months) appeared to be protective from asthma.

189 Background: Gastric cancer (GC) is a high mortality cancer in the US. Differences in risk factors by anatomic location and race/ethnicity have been suggested but remain understudied in the US population. Methods: The Multiethnic Cohort (MEC) is a prospective cohort study that collected data on 5 racial/ethnic groups [Whites (W), Blacks (B), Latino (L), Japanese-American (JA), and Hawaiian (HA)] from Hawaii and Los Angeles in 1993-1996. Participants completed a detailed baseline survey and were followed for development of incident cancer. Cox regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI) to identify GC risk factors by anatomic location (cardia, non-cardia) and by race/ethnicity. Results: Data from 192,626 participants was available. The cohort was 25% W, 17% B, 23% L, 28% JA, and 7% HA. During a median follow up of 20.3 years, 1,109 non-cardia and 201 cardia incident GCs were diagnosed. Older age (per year, non-cardia HR 1.08, 95% CI 1.07-1.92; cardia HR 1.06, 95% CI 1.05-1.09), male sex (non-cardia HR 1.6, 95% CI 1.4-1.8; cardia HR 3.0, 95% CI 2.1-4.4), and current (non-cardia HR 1.7, 95% CI 1.5-2.2, cardia HR 3.4, 95% CI 2.2-5.3) or former (non-cardia HR 1.3, 95% CI 1.1-1.5; cardia HR 2.0, 95% CI 1.3-2.9) smoking were associated with both cancer types. Notably, race/ethnicity (ref W: B HR 3.0, 95% CI 2.2-4.0; L HR 2.5, 95% CI 1.8-3.3; JA HR 3.9, 95% CI 3.0-5.1; HA HR 3.9, 95% CI 2.8-5.5), foreign-born (ref: self & parents US born: HR 1.3 95% CI 1.1-1.7), and family history of GC (OR 1.9, 95% CI 1.5-2.3) were associated with non-cardia GC. BMI ≥30 (HR 1.6, 95% CI 1.1-2.3), having ≥1 drink/week (HR 1.6, 95% CI 1.1-2.3), and being JA (ref W: HR 1.9, 95% CI 1.2-2.9) were associated with cardia GC. Risk factors other than age differed by race/ethnicity for non-cardia GC. Male sex was a risk factor for B, L and JA only. Having less than a high school education was a risk factor for B and JA only, smoking a risk factor for L and JA only, and having diabetes a risk factor for B only. Being in the highest sodium intake quartile was a risk factor among W and HA. A family history of GC was a risk factor for W, L, and JA. Having foreign-born parents was a risk factor for W and being foreign-born was a risk factor for JA. Conclusions: GC risk factors differ between subtypes and, for non-cardia, between race/ethnic groups. These differences provide an insight into the etiology of GC and the disproportionate incidence rates in high-risk groups, potentially aiding in the design of targeted intervention strategies.

Background & Purpose: Young to middle aged African Americans (AA) are at greater risk for a first-ever stroke, severe neurologic disability, and stroke-related mortality, than Caucasians of similar age; however, it remains unclear what role a family history of stroke (FHS) plays in promoting adoption of healthier lifestyles in this cohort. The purpose of this study was to explore differences between rural Stroke Belt AA with a FHS (e.g. parent/grandparent/sibling) on modifiable stroke risk factors, knowledge, perceived threat and perceived control of stroke, and exercise behaviors to AA without a FHS. Methods: A cross-sectional study was conducted recruiting AA aged 19-54 from the Black Belt region of Alabama via a mobile health clinic. Participants’ perceptions, knowledge, exercise history/intent, physiologic data, and health history were recorded. Results: Participants (N=66) averaged 43.3+9.4 years, were 71% female, with at least 12 years of school (89%), and unemployed (62%). Common risk factors were insufficient exercise (76%), obesity (59%), hypertension (53%; blood pressure M=145+17.6/88.3+12.9), and cigarette smoking (38%). Participants with a FHS (n=33) did not differ on average number of risk factors compared to those without a FHS (FHS 2.8+1.4 vs. 2.2+1.5; t(64)= 1.73, p=.089), nor did they differ on physiologic data. However, participants with a FHS were more likely to report a history of hypertension (67%) compared to those without a FHS (33%; χ2 =4.93, p <.05). There were no significant differences between groups for knowledge of stroke risk factors, perceived threat and perceived control of stroke, or recent exercise performance, although participants with a FHS (3.4+1.2) had significantly lower future intentions to exercise compared to those without a FHS (3.9+0.8); t(64)=2.45, p<.05). Conclusions: Although FHS is a significant non-modifiable risk factor for stroke and was common in this young to middle-aged AA cohort, FHS did not drive perceived stroke risk, risk factor control, or current/future intentions to exercise. Identification of interventions designed to personalize FHS as a key stroke risk factor, while promoting lifestyle change and self-management, may play an important role in future primary stroke prevention.

Background: Venoarterial extracorporeal membrane oxygenation support is a well-established tool in the care of severe refractory cardiac and respiratory failure. The application of this support may serve as a bridge to transplant, recovery or to implantation of a ventricular assist device. Venoarterial extracorporeal membrane oxygenation support can be administered through an open surgical access via the common femoral or axillary artery or a percutaneous approach using Seldinger technique. Both techniques may obstruct the blood flow to the lower limb and may cause a significant ischemia with possible limb loss. Malperfusion of the distal limb can be avoided using an ipsilateral distal limb perfusion, which may be established by adding a single-lumen catheter during venoarterial extracorporeal membrane oxygenation treatment to overcome the obstruction. The aim of this study is to distinguish the presence or absence of a distal limb perfusion regarding the incidence of distal limb ischemia. Furthermore, expected risk factors of open and percutaneous femoral venoarterial extracorporeal membrane oxygenation installation were evaluated for the development of distal limb ischemia. Methods: Between January 2012 and September 2015, 489 patients received venoarterial extracorporeal membrane oxygenation support at our institution. In total, 307 patients (204 male, 103 female) with femoral cannulation were included in the analysis. The cohort was distinguished by the presence (group A; n = 237) or absence (group B; n = 70) of a distal limb perfusion during peripheral venoarterial extracorporeal membrane oxygenation treatment. Furthermore, a risk factor analysis for the development of distal limb ischemia was performed. Results: The main indications for venoarterial extracorporeal membrane oxygenation therapy were a low cardiac output syndrome (LCOS) (53%) and failed weaning of extracorporeal circulation (23%). A total of 23 patients (7.49%) under venoarterial extracorporeal membrane oxygenation support developed severe distal limb malperfusion (3.38% in group A vs 21.42% in group B). Preemptive installation of distal limb perfusion extended the intervention-free intervals to 7.8 ± 19.3 days in group A and 6.3 ± 12.5 in group B. A missing distal limb perfusion (p = 0.001) was identified as a main risk factor for critical limb ischemia. Other comorbidities such as arterial occlusion disease (p = 0.738) were not statistically significantly associated. Surgical intervention due to vascular complications after extracorporeal membrane oxygenation explantation was needed in 14 cases (4.22% in group A and 5.71% in group B). Conclusion: We were able to identify the absence of distal limb perfusion as an independent risk factor for the development of critical distal limb ischemia during femoral venoarterial extracorporeal membrane oxygenation treatment. The application of a distal limb perfusion should be considered as a mandatory approach in the context of femoral venoarterial extracorporeal membrane oxygenation treatment regardless of the implantation technique.

Abstract Background The global observational BREAKOUT study investigated germline BRCA mutation (gBRCAm) prevalence in a population of patients with human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (MBC). Methods Eligible patients had initiated first-line cytotoxic chemotherapy for HER2-negative MBC within 90 days prior to enrollment. Hormone receptor (HR)-positive patients had experienced disease progression on or after prior endocrine therapy, or endocrine therapy was considered unsuitable. gBRCAm status was determined using baseline blood samples or prior germline test results. For patients with a negative gBRCAm test, archival tissue was tested for somatic BRCAm and homologous recombination repair mutations (HRRm). Details of first-line cytotoxic chemotherapy were also collected. Results Between March 2017 and April 2018, 384 patients from 14 countries were screened and consented to study enrollment; 341 patients were included in the full analysis set (median [range] age at enrollment: 56 [25–89] years; 256 (75.3%) postmenopausal). Overall, 33 patients (9.7%) had a gBRCAm (16 [4.7%] in gBRCA1 only, 12 [3.5%] in gBRCA2 only, and 5 [1.5%] in both gBRCA1 and gBRCA2). gBRCAm prevalence was similar in HR-positive and HR-negative patients. gBRCAm prevalence was 9.0% in European patients and 10.6% in Asian patients and was higher in patients aged ≤ 50 years at initial breast cancer (BC) diagnosis (12.9%) than patients aged > 50 years (5.4%). In patients with any risk factor for having a gBRCAm (family history of BC and/or ovarian cancer, aged ≤ 50 years at initial BC diagnosis, or triple-negative BC), prevalence was 10.4%, versus 5.8% in patients without these risk factors. HRRm prevalence was 14.1% (n = 9/64) in patients with germline BRCA wildtype. Conclusions Patient demographic and disease characteristics supported the association of a gBRCAm with younger age at initial BC diagnosis and family history of BC and/or ovarian cancer. gBRCAm prevalence in this cohort, not selected on the basis of risk factors for gBRCAm, was slightly higher than previous results suggested. gBRCAm prevalence among patients without a traditional risk factor for harboring a gBRCAm (5.8%) supports current guideline recommendations of routine gBRCAm testing in HER2-negative MBC, as these patients may benefit from poly(ADP-ribose) polymerase (PARP) inhibitor therapy.

Abstract Background Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex disease, whose exact cause remains unclear. A wide range of risk factors has been proposed that helps understanding potential disease pathogenesis. However, there is little consistency for many risk factor associations, thus we undertook an exploratory study of risk factors using data from the UK ME/CFS Biobank participants. We report on risk factor associations in ME/CFS compared with multiple sclerosis participants and healthy controls. Methods This was a cross-sectional study of 269 people with ME/CFS, including 214 with mild/moderate and 55 with severe symptoms, 74 people with multiple sclerosis (MS), and 134 healthy controls, who were recruited from primary and secondary health services. Data were collected from participants using a standardised written questionnaire. Data analyses consisted of univariate and multivariable regression analysis (by levels of proximity to disease onset). Results A history of frequent colds (OR = 8.26, P <= 0.001) and infections (OR = 25.5, P = 0.015) before onset were the strongest factors associated with a higher risk of ME/CFS compared to healthy controls. Being single (OR = 4.41, P <= 0.001), having lower income (OR = 3.71, P <= 0.001), and a family history of anxiety is associated with a higher risk of ME/CFS compared to healthy controls only (OR = 3.77, P < 0.001). History of frequent colds (OR = 6.31, P < 0.001) and infections before disease onset (OR = 5.12, P = 0.005), being single (OR = 3.66, P = 0.003) and having lower income (OR = 3.48, P = 0.001), are associated with a higher risk of ME/CFS than MS. Severe ME/CFS cases were associated with lower age of ME/CFS onset (OR = 0.63, P = 0.022) and a family history of neurological illness (OR = 6.1, P = 0.001). Conclusions Notable differences in risk profiles were found between ME/CFS and healthy controls, ME/CFS and MS, and mild-moderate and severe ME/CFS. However, we found some commensurate overlap in risk associations between all cohorts. The most notable difference between ME/CFS and MS in our study is a history of recent infection prior to disease onset. Even recognising that our results are limited by the choice of factors we selected to investigate, our findings are consistent with the increasing body of evidence that has been published about the potential role of infections in the pathogenesis of ME/CFS, including common colds/flu.

Objective To discuss the correlation among intracranial arterial stenosis and its risk factors. Methods A total of 486 patients with transient ischemic attack (TIA) or ischemic cerebral infarction were examined using color doppler flow imaging (CDFI) and transcranial doppler ultrosonography (TCD). According to the degrees of extracranial arterial stenosis, patients with mild-to-moderate extracranial stenosis were classified into group A (435 cases) while those with constant severe stenosis or occlusion were classified into group B (51 cases). The differences between the two groups of risk factors were compared, and the multi-factor logistic regression analysis of risk factors associated with moderately severe intracranial arterial stenosis was performed. Results ① The risk factors that were significantly associated with intracranial arterial stenosis included age (P = 0.034) and gender (P = 0.044). ② Intracranial artery stenosis was observed in both anterior and posterior cerebral arteries in patients with hypertension, diabetes, and coronary heart disease respectively (P < 0.05). ③ Compared with group A, patients in group B were older (P = 0.000), with a higher proportion of men (P = 0.037), and the intracranial arterial stenosis degrees were significantly higher (P = 0.013). ④ Multi-factor logistic regression analysis showed that diabetes is a risk factor for moderately severe intracranial arterial stenosis (P < 0.05), and hyperlipidemia is a protective factor (P = 0.012). Conclusions Age, gender, hypertension, diabetes, coronary heart disease, and smoking are risk factors for the distribution of intracranial arterial stenosis. The degrees of intracranial arterial stenosis are related with extracranial arterial stenosis. Diabetes is a risk factor for moderately severe intracranial arterial stenosis while hyperlipidemia is a protective factor.

10032 Background: We recently reported the results in C & A with low risk (group A), intermediate risk (group B) and high risk (group C) mature B-NHL treated on FAB/LMB 96 (Gerrard et al, Br J Haematol, 2008; Patte et al, Blood, 2007; Cairo et al, Blood, 2007, respectively). Adolescent age (15–21 yrs) has historically been considered to be an independent risk factor for poor outcome in subsets of mature B-NHL (Hochberg/Cairo et al, Br J Haematol, 2008; Burkhardt et al, Br J Haematol 2005; Cairo et al, Br J Haematol, 2003). Methods: We analyzed the EFS of all pts treated on FAB/LMB 96 and the following risk factors were significant in a univariate and Cox multivariate analysis: age (<15 vs ≥15 yrs), stage I/II vs III/IV, primary sites, LDH <2 vs ≥2 NL and histology (DLBCL vs BL/BLL). Results: 1111 pts (15%, 15–21 years) were treated with group A (N = 132), group B (N = 744), and group C (N = 235) therapy. Five year EFS (CI95) for all, A, B, C pts was 86% (84%,88%), 98% (93%, 100%), 87%% (84%, 89%), and 79%% (73%,84%), respectively. Age (≥15 yrs), LDH ≥2NL, stage III/IV, and BM+/CNS+ and histology were significant univariate risk factors for decreased EFS (P<0.045, <0.0001, <0.0001, <0.0001, and <0.0001 respectively). Multivariate analysis demonstrated age ≥15 yrs and DLBCL histology were no longer independent significant risk factors (p = .82 and 0.08, respectively), but LDH (RR 2.0, p = .001), stage III/IV (RR 3.8, p<0.001), and primary sites including PMBL (RR 4.0, p<.001) and BM+/CNS+ (RR 2.8, p<0.001) were independent significant risk factors for poorer outcome. Conclusions: With the use of modern short but intense FAB-LMB 96 therapy, adolescent age is no longer a poor risk factor in children with mature B-NHL. The independent risk factors identified in this study (stage, LDH, primary site) for decreased EFS in C & A mature B-NHL will form the basis of the next risk adapted international pediatric mature B-NHL trial.

It has been postulated that some children with recurrent cough but no wheeze have a mild form of asthma (cough variant asthma), with similar risk factors and an increased risk of future wheeze.This longitudinal study compared risk factors for isolated night cough and for wheeze in the Leicester Respiratory Cohort in children aged 1, 4, 6 and 9 years and compared prognosis of children with isolated night cough, children with wheeze and asymptomatic children.We included 4101 children aged 1 year, 2854 aged 4 years, 2369 aged 6 years and 1688 aged 9 years. The prevalence of isolated night cough was 10% at age 1 year and 18% in older children. Prevalence of wheeze decreased from 35% at 1 year to 13% at 9 years. Although several risk factors were similar for cough and wheeze, day care, reflux and family history of bronchitis were more strongly associated with cough, and male sex and family history of asthma with wheeze. Over one-third of preschool children with cough continued to cough at school age, but their risk of developing wheeze was similar to that of children who were asymptomatic at earlier surveys. Wheeze tracked more strongly throughout childhood than cough.In conclusion, our study showed that only some risk factors for cough and wheeze were shared but many were not, and there was little evidence for an increased risk of future wheeze in children with isolated night cough. This provides little support for the hypothesis that recurrent cough without wheeze may indicate a variant form of asthma.
