A feasibility study of the CRISP intervention; a cardiovascular risk reduction intervention in patients with an abdominal aortic aneurysm.

Abdominal aortic aneurysm (AAA) screening/surveillance is implemented widely. Those in AAA-surveillance are at high-risk of cardiovascular-events. We developed an intervention, called CRISP, using intervention-mapping, to reduce cardiovascular-risk in AAA-surveillance. This study tested the CRISP intervention in routine clinical-care. The CRISP intervention, consisting of a nurse-led cardiovascular risk assessment and subsequent lifestyle change support using a self-care workbook and low-intensity nurse input was delivered in two screening/surveillance programmes. Those consenting to take part were followed-up with cardiovascular-assessments. Fidelity of intervention-delivery was assessed quantitatively/qualitatively. 40 men (mean age 75 ± 7 years) took part over four months and followed-up for a minimum six months. A sub-group of 25 patients and nine Health Care Professionals (HCPs) were interviewed. The median number of risk-factors that patients chose to focus on was two (range 0 to 4), with physical activity (n=17) being the most popular. Participants who had a 'red light' risk factor for stress, low mood, smoking or alcohol intake were offered a referral to appropriate services. Two were offered referral to mental-health services and took it up, three declined referrals to smoking or alcohol support services. The fidelity of intervention-delivery (a score intervention components delivered to each patient based on a score from 0 to 5, with 5 being highest delivery fidelity) was generally low. The highest mean score (on a 0-5 scale) for the nurse assessment was 1.5 for engaging the participant, lowest 0.5 for exploring the importance for selected lifestyle behaviours. In qualitative interviews, the intervention was liked by patients/HCPs. Based on qualitative interviews and observations, the low fidelity of intervention-delivery was due to intervention-training not being detailed. CRISP can be delivered in AAA-surveillance, but fidelity of delivery is low. The intervention and its training need to be refined/tested before wider implementation. ISRCTN9399399518/11/20).

Lifestyle factors, physical health, and life satisfaction under different changes in depressive symptoms among Chinese community-dwelling older adults: A longitudinal analysis.

The study aims to investigate the long-term impact of lifestyle-related factors and physical health on life satisfaction and depressive symptoms among Chinese community-dwelling older adults. Using data from the China Health and Retirement Longitudinal Study (CHARLS), the analytic sample of this study included 1,068 older adults who had participated in the surveys in both 2011 and 2018. Multivariate regression was employed to analyze both cross-sectional and longitudinal relationships between lifestyle-related factors, physical health, and subjective well-being - specifically depressive symptoms and life satisfaction. Additionally, the model tested how these factors correlate with life satisfaction across different groups of depressive symptom changes among older adults, categorized as not at risk of depression, intermittent depression, and chronic depression. Multimorbidity was significantly related to baseline and follow-up depressive risk in older adults. Shorter sleep duration was associated with baseline depression risk. Current alcohol drinkers reported significantly more severe depressive symptoms than non-drinkers. At baseline, current smokers were more likely to have a lower degree of life satisfaction than nonsmokers. Among older adults with chronic depression at the 7-year follow-up, former smokers tended to have lower life satisfaction than nonsmokers. Our findings identified drinking alcohol and having a shorter sleep duration as modifiable lifestyle-related risk factors for late-life depression and smoking as a detrimental factor for life satisfaction in older Chinese adults. Multimorbidity was a significant predictor of more depressive symptoms. Our findings have implications for future psychosocial interventions that target the alleviation of depressive symptoms and the promotion of life satisfaction in older Chinese people based on their different long-term mental and physical health conditions.

Adverse childhood experiences and adult disease: Examining mediating pathways in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study.

Adverse childhood experiences (ACEs) have been linked to adulthood chronic diseases, but there is little research examining the mechanisms underlying this association. We tested pathways from ACEs to adult disease mediated via risk factors of depression, smoking, and body mass index. Prospective data from adults 18 to 74 years old from the Hispanic Community Health Study/Study of Latinos and Sociocultural Ancillary Study were used. Retrospectively reported ACEs and hypothesized mediators were measured at Visit 1 (2008-2011). Outcomes of disease prevalence were assessed at Visit 2, approximately 6 years later. The analytic sample includes 5,230 Hispanic/Latino participants with ACE data. Statistical mediation was examined using structural equation modeling on cardiometabolic and pulmonary disease prevalence and reported probit regression coefficients with 95% confidence intervals (CIs). We found a significant association between ACEs and the prevalence of asthma/chronic obstructive pulmonary disorder (standardized β = .07, 95% CI [0.02, 0.12]). In the mediational model, the direct association was nonsignificant (β = .02, 95% CI [-0.04, 0.07]) but was mediated by depressive symptoms (β = .03, 95% CI [0.02, 0.04]). There were no associations between ACEs and the prevalence of diabetes and self-reported coronary heart disease or cerebrovascular disease. However, a small indirect effect was identified via depressive symptoms and coronary heart disease (β = .02, 95% CI [0.01, 0.03]). In this diverse Hispanic/Latino sample, depressive symptoms were found to be a pathway linking ACEs to self-reported cardiopulmonary diseases, although the effects were of small magnitude. Future work should replicate pathways, confirm the magnitude of effects, and examine cultural moderators that may dampen expected associations.

Abstract P106: Association of long term blood pressure variability and Major Cardiovascular events in patients with primary aldosteronism

Objective: Long-term blood pressure variability (BPV) is associated with an increased risk of major cardiovascular events (MACE), but it is rarely reported in patients with primary aldosteronism (PA). We aim to investigate the association between long-term BPV and cardiovascular events in patients with PA. Methods: This was a retrospective cohort study which conducted at the Hypertension Center of People’s Hospital of Xinjiang Uygur Autonomous Region from January 2006 to December 2021. The study included patients with PA aged over 30 years. The primary outcome was the incidence of major cardiovascular events during the follow-up, which extended until June 2023. The BPV index encompassed four parameters: standard deviation (SD), coefficient of variation (CV), average real variability (ARV), and maximum and minimum blood pressure difference (MMD). Multivariate analysis using logistic regression was performed, adjusting for demographic variables such as age, sex, body mass index, as well as clinical characteristics including smoking and alcohol consumption. Results: A total of 2,380 patients with PA were ultimately enrolled in this study. Access to clinic blood pressure was ensured at least three times during follow-up visits, with a minimum follow-up interval of 1 month. During a median follow-up of3.6 years, there were 124 cases of MACE. The mean age of the participants was 49.36 years, with men accounting for 1,288 cases. The average blood pressure recorded was 135 mmHg. After adjusting for confounding factors such as age, sex, smoking, alcohol consumption, BMI and cardiovascular risk factors, the systolic BPV (SD, CV, ARV) was found to be significantly associated with MACE (OR= 1.03, CI 1.02-1.05; P<0.05). In the group of mean SBP≥130mmHg, SBP variability had a significant association with MACE (OR: 1.03; CI: 1.01-1.06; P<0.05). However, no significant correlation between SBP variability and MACE in group of mean SBP <130mmHg (P>0 .05). Conclusion: Focusing on long-term systolic BP SD, CV, and ARV in patients with primary aldosteronism may help to prevent the occurrence of cardiovascular events.

Risk variables of heart failure among patients in China: grey relational approach based multi-dimensional assessment study

BackgroundUnderstanding the potential risk factors of heart diseases is key to effectively managing cardiac diseases. The present study quantifies the association of identified risk factors. In addition, the study has compared the association of mortality with hypertension, uncontrolled diabetes, and uncontrolled hyperlipidemia using Grey Relational Approach (GRA) for stroke, lung diseases, smoking, stress, obesity, and lack of exercise.MethodData on risk factors of heart failure were collected from the Global Burden of Disease (GBD) study (2001–2017). From the GBD database, variables have selected the top leading risk factors responsible for mortality from cardiac diseases. Data on risk factors was analyzed using the GRA procedure (utilizing Grey [8.0] software). In the GRA method, the correlation was categorized into three components: GRA – Deng (assesses the effect of one variable specified by data on the other variables), GRA- absolute (assesses the association between variables measured), and GRA-SS (assessed the overall association between the variables measured). Stroke, lung diseases, smoking, stress, obesity, and lack of exercise were taken as dependent variables and their impact was assessed. Hypertension (high grade) uncontrolled diabetes, and uncontrolled hyperlipidemia were considered as independent variables. The relationship between dependent and independent variables was assessed.ResultsOverall correlational analysis showed that type 2 diabetes (T2DM) is the risk factor that has a strong relationship with causing heart failure and thereby increases morbidity and mortality among Chinese patients. After T2DM, the second highest risk factor associated was severe dyslipidemia which is responsible for causing heart failure. High-grade hypertension is one-third most common risk factor in causing heart failure. GRA – Deng analysis showed that T2DM is the top risk factor associated with heart failure, followed by high-grade hypertension and severe dyslipidemia (uncontrolled). GRA-absolute analysis showed that severe dyslipidemia is the top risk factor associated with heart failure, followed by high-grade hypertension and T2DM (uncontrolled). GRA-SS analysis showed that high-grade hypertension is the top risk factor associated with heart failure, followed by severe dyslipidemia and T2DM (uncontrolled).ConclusionsThe study reported that T2DM, severe dyslipidemia, and high-grade hypertension as strongly correlated with the development of heart failure after considering other several key risk factors (stroke, lung diseases, smoking, stress, obesity, and lack of exercise).Level of evidenceIV.Technical efficacyStage 5.

SOCIO-DEMOGRAPHIC AND CLINICAL PREDICTORS OF FAILURE TO ACHIEVE THE TARGET LEVEL OF BLOOD PRESSURE IN OUTPATIENTS WITH ISOLATED ARTERIAL HYPERTENSION AND IN COMBINATION WITH CARDIOVASCULAR COMORBIDITY

The problem of achieving the target level of blood pressure (TBP) is extremely relevant today, as arterial hypertension (AH) is the leading modifiable risk factor for cardiovascular complications.The aim of the study is to investigate the relationships between achievement/failure of TBP and socio-demographic and clinical characteristics in outpatients with isolated AH and in combination with cardiovascular comorbidity and to determine probable predictors of failure to achieve TBP.Material and methods. The study was carried out on the basis of the municipal non-profit enterprise “Gulsk outpatient clinic for general practice of family medicine” of the Strievsky village council, the village of Striyevo, Zvyagelsky district, Zhytomyr region The study involved 140 patients with AH, divided into three groups: isolated AH (n=60), AH+coronary heart disease (CHD) (n=35), AH+CHD+chronic heart failure (HF) (n=45). Patients were considered to have achieved the TBP if their office BP was <140/90 mm Hg when measured twice with an interval of 1 month.Results. The absence of statistically significant changes according to achievement/failure of TBP between outpatients with isolated AH and AH with cardiovascular comorbidity (χ2=3.37; p=0.185) was revealed, while in the group with isolated AH 65.00%, in the group with AH + CHD – 45.71%, in the group of AH + CHD + HF – 57.78% of people did not reach the TBP. Analyzing the relationships between the achievement/failure of TBP and age, gender, social status and modifiable risk factors (smoking, alcohol abuse and salt abuse), statistically significant differences were found only in relation to salt abuse in outpatients with AH and cardiovascular comorbidity (in the group of AH + CHD 100.00%, and in the group AH + CHD + HF 96.15% of people who abuse salt did not reach the TBP). The results of the logistic regression analysis showed that the female gender is by 4.1 times more likely to be associated with failure to achieve TBP compared to the male gender in the group with isolated AH, by 3.5 times – in the group of AH+CHD, by 3.4 times – in the group of AH+CHD+HF; salt abuse increases the risk of not reaching the TBP in the group with isolated AH by 19.4 times; by 20.8 times – in the group of AH + CHD; by 21.1times – in the group of AH + CHD + HF. Analyzing the relationship between achievement/failure of TBP and clinical characteristics of outpatients with isolated AH, the duration of the disease in persons who did not reach TBP is 2.0 times longer than the catamnesis of persons who reached TBP (p<0.001); the degree and stage of arterial hypertension significantly affects achievement/failure of TBP (χ2=22.27; p<0.001 and χ2=7.66; p=0.022, respectively). The results of the logistic regression analysis show that an increase in BP (in particular, each subsequent degree of AH) is more often associated with failure to achieve TBP both in patients with isolated AH and in patients with AH and cardiovascular comorbidity: by 2.7 times in the group with isolated AH; by 2.8 times in the group of AH + CHD; by 3.0 times – in the group of AH+CHD+HF.Conclusions. Female gender, salt abuse, and the degree of AH are statistically significant factors associated with an increased risk of not reaching the target blood pressure level both in outpatients with isolated AH and in patients with AH combined with cardiovascular comorbidity.

An Overview of Integrated Risk Factors with Prevention and Prevalence of Asthma at the Global Level

Abstract: Bronchial asthma is one of the most common chronic illnesses in childhood, adulthood and pregnancy with a current occurrence of 6-9 percent, but at an alarming rate of increase. Asthma is a complex genetic disorder that is heavily affected by the environment. In association with significant morbidity, quality of life, and healthcare costs, it is putting an increasing strain on our society. Some factors related to pregnancy, i.e., diet-related, antibiotic uses, and stress; childhood risk factors, i.e., lung function, exposure to smoking, animal etc. and adulthood risk factor, i.e., pollution-related etc., are responsible for trends in incidence and mortality due to asthma at a Global level and Indian population. Data were collected from PubMed, Web of Sciences, CINHAL, WHO Clinical trial register, Google Scholar, and official websites of various asthma societies and statistically analyzed using ANOVA tests. Data were analyzed for India and the specific population of the northern region of India during the last five years. Risk factors related to asthma at different stages, i.e., genetic, pregnancy, childhood, and adulthood, were reviewed, and the prevalence of asthma at the Global level, India and northern India, was analyzed and compared. The mean Global prevalence of asthma was found to be 281.3±14.7 (SD), whereas, for India, it was 22.78±8.605. After applying One Way ANOVA, a significant difference (t=48.44, df=4) was found between the Global and Indian prevalence of asthma, i.e., the mean difference of 259.7±11.99. The mean value was found highest in Delhi and Rajasthan, having values of 19.74±11.79 and 13.58±9.47, whereas Chandigarh and Uttar Pradesh recorded asthma’s prevalence as 11.87±7.83 and 4.32±2.32 respectively. Himachal and Haryana acquired almost equal values of asthma at 1.67±0.13 and 1.23±0.33.

Posterior Circulation Ischemic Stroke Is Associated with More Severe Forward Head Posture in Patients with Cervicalgia

Chronic risk factors of posterior circulation ischemic strokes remain unknown. There is, however, evidence that anatomical variations within the vertebrobasilar system could potentially lead to the development of posterior circulation strokes. We investigated the association of forward head posturing (FHP), a chronic anatomical change seen in patients with cervicalgia, with posterior circulation strokes. In this case-control study, we identified adult patients diagnosed with cervicalgia and ischemic posterior circulation infarcts from 2007 to 2023. Cases were paired with controls with cervicalgia without posterior circulation stroke and matched for known risk factors. C0-C2 angle, C2-C7 angle, and sagittal vertical axis shift were measured as metrics for FHP severity on lateral cervical spine x-rays. Paired t tests were applied to compare stroke risk factors and FHP between groups. Participants included 206 patients (103 cases and 103 controls) with a mean age of 64.4 years; 51.5% were female. There were no statistically significant differences between risk factors for stroke, including hypertension, hyperlipidemia, diabetes, smoking, hypercoagulable state, and atrial fibrillation. There were statistically significant differences in C0-C2 angle (30.7° vs. 23.2°, P=0.002) and sagittal vertical axis shift (35.4 mm vs. 25.3 mm, P < 0.001). This case-control matched-pair study found that in adults with cervicalgia, posterior circulation ischemic stroke was associated with more severe FHP as noted in C0-C2 angle and sagittal vertical axis shift measurements. Further, this association may be due to chronic changes in circulation flow dynamics within the vertebrobasilar system with the postural change.

Endothelium-mediated vasodilation: associations with cardiometabolic diseases and their risk factors in aging

Aim. To evaluate the association of flow-mediated vasodilation (FMD) with cardiometabolic diseases (CMDs) and their risk factors (RF) in old age.Material and methods. The study was conducted in the Russian population cohort of the HAPIEE project (Novosibirsk, 2015-2018). Endothelial function was assessed in a random subsample (788 men and women aged 55-84 years) using ultrasound measurements of the brachial artery FMD. Endothelial dysfunction (ED) was recorded with FMD &lt;10%. Cardiovascular diseases (CVD) and risk factors were assessed using standard epidemiological methods.Results. The incidence of hypertension (HTN) was 78,8% (the same in men and women), major CVDs — 21,7% and 17,1%, type 2 diabetes (T2D) — 18,7% and 19,1% in men and women, respectively. The mean FMD values were 2,7% (SD 7,32) and 3,2% (7,19), while the prevalence of ED was 88,2% and 85,8% in men and women, respectively, and did not differ significantly by sex. Men with ED had higher levels of blood triglycerides (125,1 (71,23) vs 102,7 (45,79) mg/dl; p=0,033), waist/hip circumference indices (0,94 (0,050) vs 0,92 (0,076); p=0,009) and body weight (27,7 (45,79) vs 26,5 (4,36) kg/m2; p=0,077). In women, a tendency towards an association of ED with smoking was revealed (p=0,067). There were no associations of ED with HTN, T2D and CVD in men and women.Conclusion. The PMD test demonstrated a high incidence of ED in a population sample of 55-84 years old. ED is associated with metabolic risk factors in men and smoking in women. No associations of PMD with CMDs were found, presumably due to the high incidence of ED and cumulative disease in the elderly. Modification of metabolic risk factors and smoking cessation are relevant at any age to prevent the progression of ED.

Systematic Review and Meta-Analysis of Lifestyle and Reproductive Factors Associated with Risk of Breast Cancer in Asian Women.

Assessing breast cancer risks from lifestyle and reproductive factors is critical for developing population-specific risk prediction tools. However, limited studies have evaluated these risks in recent Asian birth cohorts. We systematically reviewed articles published from January 2010 to December 2023, examining breast cancer risk factors in Asian women. Data were described narratively, estimates pooled, and prevalence and attributable proportions compared across Asian populations. Of the 128 studies reviewed, 103 reported adjusted effect sizes for meta-analysis. Lifestyle and reproductive factors were predictive of breast cancer risk in Asian women, with varying impacts on premenopausal and postmenopausal women. Relative risks were similar within Asian populations and in comparison to European populations, except for menarche, menopause, and hormone receptor therapy. However, risk factor distributions differed across populations. While alcohol intake (21%) and oral contraceptive use (20%) emerged as the most attributable modifiable risk factors in Europeans, passive smoking (24%) and higher BMI (17%, ≥24 kg/m2 among postmenopausal women) were predominant in Asians. Our study shows that while the effects of lifestyle and reproductive breast cancer risk factors are largely similar across different populations, their distributions vary. Our analysis underscores the importance of considering population-specific risk factor distributions when developing risk prediction tools for Asian populations.

Progression of Coronary Artery Calcification According to Changes in Risk Factors in Asymptomatic Individuals.

This retrospective study aimed to assess coronary artery calcium (CAC) progression in serial computed tomography measurements according to risk factor changes. In 448 asymptomatic adults who underwent CAC measurements with more than one-year intervals, CAC progression was assessed according to age, sex, variable traditional risk factors (diabetes mellitus, hypertension, hyperlipidemia, and smoking), and initial CAC score (0, 0.1-100, and >100). Univariate and multivariate logistic regression analyses were assessed for independent predictors of rapid CAC progression (ΔCAC/year > 20). During the 3.5-year follow-up, coronary artery calcifications occurred in 43 (12.8%) of 336 individuals with an initial CAC score of zero. Of 112 individuals with initial CAC presence, 60 (53.6%) had ΔCAC/year > 20. Age, male sex, body mass index, and all risk factors were significantly associated with ΔCAC/year > 20, but recently diagnosed hypertension (odds ratio [OR], 11.3) and initial CAC score (OR, 1.05) were significant independent predictors in multivariate regression analyses. CAC progression was affected by demographic and traditional risk factors; but, adjusting for these factors, recently diagnosed hypertension and initial CAC score were the most influential factors for rapid CAC progression. These findings suggest that individuals with higher initial CAC scores may benefit from more frequent follow-up scans and checks regarding risk factor changes.

Histologic Activity From Neoterminal Ileal Biopsies in Patients With Crohn's Disease in Endoscopic Remission is Associated With Postoperative Recurrence.

Following ileocolic resection (ICR), the clinical importance and prognostic implications of histologic activity on biopsies in Crohn's disease (CD) patients with endoscopic remission are not well defined. The aim of this study was to determine if histologic activity in patients with endoscopic remission is associated with future risk of endoscopic and/or radiologic postoperative recurrence (POR). In this multicenter retrospective cohort study, adult patients with CD who underwent ICR between 2009 and 2020 with endoscopic biopsies of ileal mucosa from Rutgeerts i0 on index colonoscopy were included. The composite rate of endoscopic (Rutgeerts score ≥i2b) and radiologic (active inflammation on imaging) recurrence was compared in patients with and without histologic activity using a Kaplan-Meier survival analysis. A multivariable Cox proportional hazard regression model including clinically relevant risk factors of POR, postoperative biologic prophylaxis, and histology activity was designed. A total of 113 patients with i0 disease on index colonoscopy after ICR were included. Of these, 42% had histologic activity. Time to POR was significantly earlier in the histologically active versus normal group ( P = 0.04). After adjusting for clinical risk factors of POR, histologic activity (HR 2.37, 95% CI 1.17-4.79; P = 0.02) and active smoking (HR 2.54, 95% CI 1.02-6.33; P = 0.05) were independently associated with subsequent composite POR risk. In patients with postoperative CD, histologic activity despite complete endoscopic remission is associated with composite, endoscopic, and radiographic recurrence. Further understanding of the role of histologic activity in patients with Rutgeerts i0 disease may provide a novel target to reduce disease recurrence in this population.

Comparative analysis of the prevalence of smoking and consumption of nicotine-containing products and their risk factors among students of medical and technical universities of Saint Petersburg based on data from the PROTECT study

BACKGROUND: Taking into account the importance of quitting smoking of any nicotine-containing products by young people in various social groups, a comparative analysis of the prevalence of smoking tobacco and nicotine-containing products among students of medical and technical universities in St. Petersburg was carried out. AIM: To compare the prevalence and structure of consumption of tobacco and nicotine-containing products, as well as the smoking behavior of students at medical and technical universities. MATERIALS AND METHODS: A cross-sectional cross-sectional study of a random sample of student groups included 1,105 respondents. RESULTS: The prevalence of tobacco smoking among students at a technical university was 2 times higher than at a medical university (p 0.01). Cigarette smoking was also more often noted at the onset of smoking among engineering students and in their families (p 0.05). 17.2% of North-Western State Medical University named after I.I. Mechnikov students and 14.2% of Saint Petersburg Electrotechnical University “LETI” named after V.I. Ulyanov (Lenin) students consume nicotine-containing products. Men from the medical university smoke cigarettes significantly more often than women, or use nicotine-containing products, as well as a combination of both. No similar gender differences were found at the technical university. Female doctors used ES more often than women from a technical university at the beginning of smoking (p 0.05). Men at a medical university started using nicotine-containing products more often than women, considering them the least dangerous to health (p 0.05). The example of friends was the most common reason for starting smoking among respondents from both universities (43.9 and 30.8%, respectively). Common risk factors for smoking any product among students of North-Western State Medical University and LETI were boyfriend/girlfriend smoking, smoking among one’s immediate environment. Studying in senior years was a protective factor for girls at a medical university in comparison with students at a technical university (odds ratio 0.48). CONCLUSIONS: The data obtained on the lower prevalence of tobacco smoking among medical university students compared to technical students may indirectly indicate the latter’s insufficient knowledge about the harmful effects of tobacco smoking on the body. The high prevalence of nicotine-containing products consumption in universities of various fields of study and the lack of significant differences in the share of their consumers can also be interpreted as an underestimation of the health risks of new smoking products. This requires adjustments to educational programs in order to increase students’ awareness of the potential health hazards not only of smoking cigarettes, but also of using any nicotine-containing products.

O-067 An update from the international reproductive health education collaboration

Abstract Most people want children, but many do not achieve their parenthood goals. Research shows that both men and women have limited knowledge about fertility and the factors that affect it. This includes poor knowledge about the impact of age, the most important determinant of the chance to conceive and have a healthy baby. As age at first birth is increasing in many countries, people increasingly seek assisted reproductive technology (ART) treatment due to age-related infertility. To allow people to make informed decisions about if and when to have children and to avoid age-related infertility, they need evidence-based and accessible information about fertility. Fertility awareness is defined by the World Health Organisation as ‘the understanding of reproduction, fecundity, fecundability, and related individual risk factors (e.g. advanced age, sexual health factors such as sexually transmitted infections (STIs), and lifestyle factors such as smoking, obesity) and non-individual risk factors (e.g. environmental and workplace factors); including the awareness of societal and cultural factors affecting options to meet reproductive family planning, as well as family building needs’. In 2019, an international collective of reproductive health researchers and health professionals convened to promote fertility education for the public, teachers, and health professionals. Initially called the International Fertility Education Initiative (IFEI), in 2022 the group integrated into ESHRE. In 2023, the group rebranded as the International Reproductive Health Education Collaboration (IRHEC) (www.eshre.eu/IRHEC) to reflect a life course perspective that goes beyond childbearing and includes education about all aspects of reproductive health, from puberty to menopause. The mission statement of the IRHEC is ‘To increase reproductive health awareness using the life course approach, in order to improve reproductive health and facilitate decision-making in family planning among adolescents, people of reproductive age, primary healthcare, education professionals, and policymakers through development, evaluation and dissemination of inclusive educational resources.’ We aim for our website to be a repository for a range of reproductive health educational resources for the public, health and education professionals, and researchers. This includes some resources developed by the group. In this first IRHEC report to the ESHRE conference we will describe the committee structure, the processes for joining the IRHEC Network and for nominations and elections of committee members and introduce current IRHEC committee members. We will also provide updates on completed resources to be launched during 2024 and on current and potential future projects including: • An updated fertility education poster for young people. It is based on a poster developed in 2019 which has been redesigned in response to research conducted with young people in Denmark, Sweden, and the UK. The poster is available in many different languages on the IRHEC website. • Twelve information leaflets with more in depth information on various aspects of reproductive health which have been co-designed with young people. These are also available and free to download from our website. • After years of working with schools, and a public consultation last year, IRHEC has developed a resource to help teachers deliver reproductive health education to students. It is freely available to all teachers around the world and can be used in full or in part depending on teachers’ needs. • Preparations are underway to seek funding to evaluate the teachers’ resource. We plan to use qualitative research in the first instance to explore teachers’ views on the usefulness of the resource, what parts they would use, and whether the topics covered, and the level of detail are appropriate. • We are also examining how social media can be used to deliver reproductive health education. Through this work we want to empower everyone with evidence-based education on reproductive health.

Patient satisfaction with letter-based communication of LCS pulmonary nodule results.

To analyze patient satisfaction with letter-based communication of lung cancer screening (LCS) pulmonary nodule results. Prospective randomized controlled trial of LCS between May and December 2019. All participants came from a prospective randomized controlled study on pulmonary nodule results in LCS with low-dose CT (LDCT) to analyze patient satisfaction, perception of information received via letters, preferred methods of receiving results, and dissatisfaction-relatedcharacteristics. A total of 153 patients were detected to have pulmonary nodules among 600 recruited participants in the lung cancer high-risk group screened using LDCT. Most of the patients were satisfied with receiving pulmonary nodule results via letters (78.4%; n = 120) and agreed that the letters contained an appropriate amount of information (83.7%; n = 128). Univariate logistic regression analysis revealed that satisfaction was related to age (OR, 0.905; 95% CI, 0.832-0.985), education level (OR, 0.367; 95% CI, 0.041-3.250), no family history of cancer (OR, 0.100; 95% CI, 0.011-0.914), and the number of nodules (OR, 6.028; 95% CI, 1.641-22.141). Of the patients who reported dissatisfaction with letter-based communication (7.2%; n = 11), the most common reasons cited were that they contained insufficient patient education materials and that it was difficult to comprehend the medical terminology. The majority of participants (61.4%; n = 94) reported that they would prefer the letter-based communication. No correlation was identified between satisfaction and gender, smoking status, alcohol consumption, risk factors, nodule size, or nodule location. Patients were generally satisfied with receiving their LCS pulmonary nodule results via letters, reporting that the letters included adequate information about their diagnosis and follow-up steps. This may provide a basis for feasible result communication via letters for cancer screening programs in underdeveloped regions inChina.

Prevalence of Chronic Obstructive Pulmonary Disease and Its Associated Risk Factors in Yunnan Province, China: A Population Based Cross-Sectional Study.

Chronic obstructive pulmonary disease (COPD) is a significant disease impacting health and quality of life. Yunnan Province, a major tobacco producer, lacks comprehensive COPD studies. The purpose of this study is to describe the epidemic situation of COPD in Yunnan province and explore its influencing factors. This study is a cross-sectional research conducted in a representative sample of adults aged 20 and older from 13 prefectures and cities in Yunnan Province, China. COPD was diagnosed using post-bronchodilator pulmonary function tests. Demographics were analyzed with descriptive statistics. The influencing factors of COPD were examined by using the multivariate logistic regression models. Our study found that high-risk individuals for COPD accounted for 20.30% of the screened population aged 20 and above, with a COPD prevalence of 27.18% among this high-risk group. Male had a higher prevalence (33.01%) than did female (16.35%; p<0.001 for sex difference). Additionally, the proportion of severe and extremely severe COPD cases in Yunnan Province was higher than the national average and other provinces. After considering the potential confounding variables, male (OR=2.291, 95% CI: 1.584-3.313), age (OR=1.501, 95% CI: 1.338-1.685), underweight (OR=1.747, 95% CI: 1.225-2.491), previous smoking (OR=1.712, 95% CI: 1.182-2.478), passive smoking (OR=1.444, 95% CI: 1.159-1.800), and a history of respiratory system diseases in childhood (OR=2.010, 95% CI: 1.346-3.001) were significantly associated with an increased risk of COPD. Conversely, being overweight (OR=0.636, 95% CI: 0.489-0.828), and residing in high-altitude counties (OR=0.445, 95% CI: 0.263-0.754) were negatively correlated with the risk of COPD. There is significant prevalence of COPD (27.18%) among high-risk population aged 20 and above in Yunnan Province, China. Apart from male, smoking, BMI and other known risk factors for COPD. We found that high-altitude residence had a lower prevalence of COPD. There is no significant difference in COPD prevalence between Han and ethnic minority populations.

Molecular Mechanisms and Potential Predictive Biomarkers in Advanced Non-small Cell Lung Cancer: A Summary of Current and Future Trends

Non-small-cell lung cancer (NSCLC) accounts for 85% of lung cancer cases and is associated with different risk factors (smoking habits, gender, and age). In this scenario, many studies have been conducted to pursue improvement of survival, faster and better therapy response, reduced adverse events, and expanded available therapies and treatments against tumor resistance to drugs. These studies have focused on defining the most prevalent NSCLC biomarkers (EGFR, HER2, ALK, MET, ROS1, BRAF, KRAS G12C, HER3, NTRK, and NRG1) and their actionability. It is noteworthy that expressed kinase receptors can have overlapping mechanisms of activation of different pathways (JAK-STAT, MAPK, PI3K-AKT-mTOR, and PLC-c), which can lead to the same outcome of cell proliferation, migration, and survival resulting in increased tumor resistance to treatment. This review provides an overview of the latest findings regarding NSCLC treatment, emphasizing particular biomarkers and potential molecularly altered pathways implicated as targeted therapies. Additionally, it explores the clinical significance of the proposed treatments, their implication on progression-free survival, ongoing clinical trials, and their perspective of evolution so far.

Hemostasis parameters in patients with arterial hypertension, multifocal atherosclerosis and risk factors

Aim. To determine the features of hemostasis system disorders and the possibility of their correction in patients with arterial hypertension (AH) and multifocal atherosclerotic lesions (MFA) with risk factors indicated.Materials and methods. The study included 135 patients (mean age 53.7 ± 7.76 years), including 80 patients with controlled AH stage and II (group 1) and 55 patients with controlled AH stage III who had ischemic stroke (group 2). Among all patients studied, 33 patients (24.4 %) were smokers. All 135 patients received comparable antihypertensive, antiplatelettherapy (acetylsalicylic acid at a dose of 100 mg/day), had MFA and target lipid spectrum values.Results. Procoagulant shifts are noted already in patients with AH stage I and II, especially in the presence of smoking. Such indices of global thrombodynamics test as initial clot growth rate, average clot growth rate, clot size significantly exceed the reference values and indicate high prothrombogenic potential in patient with AH and MFA. Prescription of dual antiplatelet therapy allows normalization of identified disorders. Presence of risk factors (smoking) aggravates existing hemostasis disorders in patients with AH and MFA.Conclusion. Smoking cessation, optimization of risk factors and complex antihypertensive, hypolipidemic and antithrombotic therapy are the basis of treatment of patients with AH and MFA and can be considered as priority measures to reduce morbidity and mortality in this patient population.

Cannabis, Tobacco Use, and COVID-19 Outcomes

It is unclear whether cannabis use is associated with adverse health outcomes in patients with COVID-19 when accounting for known risk factors, including tobacco use. To examine whether cannabis and tobacco use are associated with adverse health outcomes from COVID-19 in the context of other known risk factors. This retrospective cohort study used electronic health record data from February 1, 2020, to January 31, 2022. This study included patients who were identified as having COVID-19 during at least 1 medical visit at a large academic medical center in the Midwest US. Current cannabis use and tobacco smoking, as documented in the medical encounter. Health outcomes of hospitalization, intensive care unit (ICU) admission, and all-cause mortality following COVID-19 infection. The association between substance use (cannabis and tobacco) and these COVID-19 outcomes was assessed using multivariable modeling. A total of 72 501 patients with COVID-19 were included (mean [SD] age, 48.9 [19.3] years; 43 315 [59.7%] female; 9710 [13.4%] had current smoking; 17 654 [24.4%] had former smoking; and 7060 [9.7%] had current use of cannabis). Current tobacco smoking was significantly associated with increased risk of hospitalization (odds ratio [OR], 1.72; 95% CI, 1.62-1.82; P < .001), ICU admission (OR, 1.22; 95% CI, 1.10-1.34; P < .001), and all-cause mortality (OR, 1.37, 95% CI, 1.20-1.57; P < .001) after adjusting for other factors. Cannabis use was significantly associated with increased risk of hospitalization (OR, 1.80; 95% CI, 1.68-1.93; P < .001) and ICU admission (OR, 1.27; 95% CI, 1.14-1.41; P < .001) but not with all-cause mortality (OR, 0.97; 95% CI, 0.82-1.14, P = .69) after adjusting for tobacco smoking, vaccination, comorbidity, diagnosis date, and demographic factors. The findings of this cohort study suggest that cannabis use may be an independent risk factor for COVID-19-related complications, even after considering cigarette smoking, vaccination status, comorbidities, and other risk factors.
