Identifying the Relationship Between Residential Type and Health Outcomes of the Community-Dwelling Thai Older Adults in the Baseline Analysis of a Cluster-Randomized Controlled Trial

Background/Objectives: As people age, their environment plays a critical role in shaping their health. With Thailand’s rapidly aging population, it is crucial to understand how different living environments affect the well-being of older adults. This study examines differences in biopsychosocial health indicators between older adults living in village communities and private housing estates in Chiang Mai, Thailand. Methods: A cross-sectional study was conducted using baseline data from the Community-Integrated Intermediary Care (CIIC) Service Model, a Cluster Randomized Controlled Trial in Thailand (TCTR20190412004). The study included 2788 older adults (aged 60+). Of these, 89.49% resided in village communities, and 10.51% in private housing estates. Validated instruments were used to assess health indicators. Descriptive statistics, multivariate analysis of variance, and multiple logistic regression analyses were performed. Results: Older adults in private housing estates had significantly lower odds of experiencing pain or discomfort (Adj OR: 0.64, 95% CI: 0.49–0.84) and were 1.36 times more likely to report positive perceived health. However, they had lower odds of perceiving themselves as physically and socially active (Adj OR: 0.74, 95% CI: 0.57–0.97) and were 0.30 times less likely to rate their quality of life higher (Adj OR: 0.30, 95% CI: 0.22–0.40) compared to their village community counterparts. Conclusions: The residential environment significantly influences older adults’ health and well-being. Tailored health promotion interventions should leverage the unique strengths of both village communities and private housing estates to enhance social connections, physical activity, and quality of life, promoting healthy, active aging across diverse settings.

Pathogenic cardiomyopathy gene variants inform prognosis in atrial fibrillation: results from exome sequencing in over 17,000 patients in TIMI trials

Abstract Background Rare genetic variants in cardiomyopathy genes are associated with risk of atrial fibrillation (AF), even in the absence of overt ventricular dysfunction. Data on clinical outcomes for rare genetic variant carriers among patients with AF remain sparse. Purpose We aimed to study the prognostic implication of rare pathogenic/likely pathogenic (PLP) variants for dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC) in patients with AF from large, well-phenotyped randomized clinical trials. Methods and results Rare variants were called using exome sequencing data in 5 large clinical trials from the TIMI study group (ENGAGE-AF, FOURIER, SAVOR, PEGASUS, DECLARE). PLP variants for cardiomyopathy were identified using phenotype- and gene-specific curation of protein-truncating variants and high-confidence variant classifications from the ClinVar database. In 17,190 patients with a history of AF, we identified 421 (2.4%) PLP variant carriers (age 67±10, 35% women) and 16,769 (97.6%) pts without PLP variants (age 70±9, 36% women). Among these individuals, we identified 265 DCM carriers (1.5%), 106 (0.6%) HCM carriers and 54 (0.3%) ARVC carriers. In this cohort, 9,275 (54%) had a history of heart failure (HF) and 2,991 (17.4%) prior ischemic stroke. Over 2.5 years median follow-up, 1,365 pts (7.9%) were hospitalized for HF, 599 (3.5%) had an ischemic stroke, and 1147 (6.7%) died of cardiovascular causes. In logistic regression analyses adjusting for age, sex, trial, and principal components of ancestry, PLP variants were significantly associated with a history of HF (OR 1.66, p<0.0001), most notably for DCM variants (OR 1.97, 1.48-2.62, p<0.0001). PLP variants were independently associated with incident HF admissions (adj HR 1.75, 1.39-2.29, p<0.0001), most notably for HCM (adj HR 2.59, 1.68-3.99, p<0.0001) and ARVC variants (adj HR 2.50, 1.34-4.66, p=0.004). The increased risk of HF admissions remained consistent in patients with (adj HR 1.49, 1.11-2.00, p=0.009) and those without (adj HR 1.88, 1.00-3.54, p=0.049) a history of HF. PLP variants were also associated with higher risk of cardiovascular death (adj HR 1.46, 1.06-2.02, p=0.02), most notably for DCM variants (adj HR 1.77, 1.21-2.58, p=0.003). In contrast, PLP variants were not associated with history of ischemic stroke at baseline (adj OR 0.99, p=0.96) nor with incident ischemic stroke (adj HR 0.95, p=0.84). Conclusion In patients with AF, rare cardiomyopathy gene variants are associated with increased risks of HF and of cardiovascular death, but not stroke. These results, collected from large well-phenotyped randomized clinical trials, demonstrate an important prognostic implication for rare genetic variants for CMP in pts with AF.

Two different hybrid vascular access closure strategies post transcatheter aortic valve implantation

Abstract Background The hybrid strategy combining plug-based and suture-based vascular closure devices (VCD) was introduced as a promising technique for vascular access hemostasis after transcatheter aortic valve implantation (TAVI) with satisfactory outcomes. However, data comparing two plug-based VCDs each in the combination with a suture-based VCD, namely ProGlide/FemoSeal (P/FS) with ProGlide/AngioSeal (P/AS) VCDs, is still lacking. Aim To compare the 30-day outcome of the hybrid strategy using P/AS versus P/FS for vascular access site closure after TAVI. Methods A retrospective single Centre observational study included 608 patients recruited from a prospective TAVI registry between 2016 and 2022. The composite endpoint was defined as any VCD related major vascular complications and/or bleeding more than type 1 according to Valve Academic Research Consortium (VARC-3) criteria. Results The current study reported a significantly higher rate of composite endpoint in P/AS group, which was driven by higher rate of major bleeding (5.4% vs 1.4%, p=0.036). We also found a higher rate of VCD related minor bleeding in P/AS group (16.3% vs 8.1%, p=0.013). Successful access site hemostasis was achieved in 83.1% of P/FS group versus 71.7% in P/AS group (p=0.006). The presence of anterior wall calcification at the access site was significantly associated with the composite endpoint (adj OR 2.49; 95% CI (1.08 – 5.75), p=0.032). Conclusions The hybrid strategy for large bore vascular access closure using P/FS showed a potentially better 30-day outcomes compared with P/AS. The presence of anterior calcification at the access site carries a significant risk of VCD related complications.

Changes in biopsychosocial factors based on transportation independence among older adults: A one-year study post-COVID-19 movement restrictions

IntroductionThe global COVID-19 pandemic prompted widespread lockdown measures, impacting transportation systems and specifically affecting the mobility of older adults, which could result in changes to their biophysical, psychological and social health, or better known as biopsychosocial health. However, limited information exists regarding the alterations in the biopsychosocial aspects of older adults during and after the COVID-19 movement restrictions, as well as their association. The objective of this study is to investigate the biopsychosocial dynamics associated with navigating transportation during and after the recovery phase of COVID-19 pandemic. Additionally, it aims to determine the association between transportation independence status and various biopsychosocial factors. MethodsA sub-sample of 100 individuals aged 60 years and above (mean age ± SD: 68.4 ± 5.3), from earlier cross-sectional study were recruited in a one year follow up study. Face-to-face interviews were conducted by the same researcher from baseline to obtain older adults’ sociodemographic health status, anthropometric measurements, functional status, depressive symptoms, nutritional status, cognitive status, visual assessment, physical activity and physical performance and transportation independence. Bivariate logistic regression was performed to examine the association. ResultsWhile there were no significant changes in transportation independence among older adults during and after the COVID-19 movement restriction, there were noticeable increases in outdoor mobility and certain changes in biopsychosocial factors. Results revealed higher fat mass (Adj OR = 1.20, 95% CI: 1.03–1.41, p < 0.05), poorer performance in Timed up and Go (TUG) (Adj OR = 1.40, 95% CI: 1.03–1.88, p < 0.05) test, poorer Hand Grip Strength (HGS) (Adj OR = .85, 95% CI: .74–.98, p < 0.05) and changes in Instrumental Activities of Daily Living (IADL) (p < 0.05) are associated with restricted transportation in older adults. ConclusionThe findings of this study highlight the importance of biopsychosocial health factors, such as body composition, physical performance, and function, which may be influenced by transportation independence among older adults.

Predictive factors for tuberculous peripheral pulmonary lesions during radial endobronchial ultrasound

BackgroundTuberculosis frequently poses diagnostic challenge when it presents as a peripheral pulmonary lesion (TB-PPL). The growing use of radial endobronchial ultrasound (rEBUS) for PPL biopsy highlights the need to identify predictive factors for TB-PPL, which is crucial for procedure safety. MethodsA six-year retrospective review at our institution on adult patients with TB and malignant-PPL diagnosed from rEBUS procedure from October 1, 2016, to December 31, 2022. Clinical, radiological, procedural, histological and microbiological data were extracted and analysed. Results387 PPLs were included in our cohort, 32 % were TB-PPL and 68 % were malignant-PPL. The median age was 63 (IQR 55–70) years, with the TB-PPL group significantly younger. The median size of the target lesion was 2.90 (IQR 2.26–4.00) cm. The overall rEBUS diagnostic yield was 85.3 %, with a 1.3 % pneumothorax risk. Multivariate analysis identified independent predictors for TB-PPL, including age <60 years (adj OR 2.635), target lesion size <2 cm (adj OR 2.385), upper lobe location (adj OR 2.020), presence of a cavity on pre-procedural CT (adj OR 4.186), and presence of rEBUS bronchogram (adj OR 2.722). These variables achieved an area under the curve of 0.729 (95 % CI 0.673–0.795) with a diagnostic accuracy of 75.49 % (95 % CI 70.68–79.88). ConclusionsDespite non-specific radiological findings in TB-PPL, our study identifies younger age, target lesion size less than 2 cm, upper lobe location, the presence of cavitation, and rEBUS bronchogram were independent clinical predictors for TB-PPL. This prediction model potentially helps mitigate the risk of accidental TB exposure during bronchoscopic procedures. A future prospective cohort study to validate these findings is essential to allow proper triaging of patient planning for rEBUS procedure.

High dietary antioxidant intake linked to lower risk of myocardial infarction: a nested case-control study

BackgroundIn developing nations, myocardial infarction (MI) remains a significant contributor to deaths from sudden cardiac arrest, with diet playing a key role in its incidence through oxidative stress mechanisms. Although the connection between the Dietary Antioxidant Index (DAI) and cardiovascular diseases has been demonstrated in some studies, the relationship between DAI and MI has not been extensively explored. Therefore, this research aims to investigate this association.MethodsWe conducted a nested case-control study involving 156 MI cases and 312 healthy controls, utilizing data from the Fasa Adults Cohort Study (FACS), a population-based study of individuals aged 35–70 residing in Fasa, Iran, with 11,097 participants included at baseline. The DAI was determined by normalizing the intake values of six dietary vitamins and minerals, adjusting by subtracting the global mean, and then dividing by the global standard deviation. MI diagnosis was established by an experienced cardiologist using electronic medical records. Conditional logistic regression was employed to examine the association between DAI and MI.ResultsThere were no significant differences between the case and control groups in terms of age (P = 0.96), gender distribution (P = 0.98), and education level (P = 0.38). In a multiple conditional logistic regression analysis, after adjusting for key variables—including body mass index (BMI), smoking status, education level, and serum levels of triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), fasting blood sugar (FBS), saturated fatty acids (SFA), and polyunsaturated fatty acids (PUFA)—an inverse association was found between DAI and the risk of myocardial infarction (MI) [adjusted Odds Ratio (Adj OR) = 0.88, 95% Confidence Interval (CI): 0.85–0.92; P < 0.001].ConclusionsThis study highlights the crucial role of the DAI in reducing the risk of myocardial infarction. Promoting diets rich in antioxidants presents a straightforward and effective strategy for MI prevention and the promotion of cardiovascular health, underscoring the novelty and significance of this research in dietary approaches to disease prevention.

Association between blood pressure variability and clinical outcomes after successful thrombectomy in acute basilar artery occlusion stroke patients: A multicenter cohort study

BackgroundLimited data are available on the appropriate choice of blood pressure management strategy for patients with acute basilar artery occlusion (BAO) treated with mechanical thrombectomy (MT). We evaluated the impact of blood pressure variability on clinical outcomes after MT in patients with acute BAO. MethodsThis multicenter cohort study included 108 patients with acute BAO who underwent successful emergency thrombectomy at two comprehensive stroke centers from 2016 to 2021. Blood pressure was measured hourly during the first 24 h after successful reperfusion. Blood pressure variability was calculated as mean arterial pressure (MAP) assessed by the standard deviation (SD). Multivariate logistic models were used to investigate the association between BPV, the primary outcome (futile recanalization, 90‐day modified Rankin Scale score 3–6), and the secondary outcome (30-day mortality). Subgroup analysis was performed as a sensitivity test. ResultsFutile recanalization occurred in 60 (56 %) patients, while 26 (24 %) patients died within 30 days. In the fully adjusted model, MAP SD was associated with a higher risk of futile recanalization (OR adj=1.36, per 1 mmHg increase, 95 % CI: 1.09–1.69, P=0.006) and 30-day mortality (OR adj=1.56, per 1 mmHg increase, 95 % CI: 1.20–2.04, P=0.001). A significant interaction between MAP SD and the lack of hypertension history on futile recanalization (P<0.05) was observed. ConclusionsAmong recanalized acute BAO ischemic patients, higher blood pressure variability during the first 24 h after MT was associated with worse outcomes. This association was stronger in patients without a history of hypertension.

Factors influencing limb movements in post-stroke patients

BackgroundStroke is the leading cause of long-term disability impacting patients’ daily lives. Adequate and ongoing rehabilitation is a necessity. Due to disability problems, rehabilitation in the health care system is limited. Traditional medicine has been promoted in Thailand for stroke rehabilitation, with physical therapy as the primary treatment plan. However, despite more options, many patients still receive inadequate rehabilitation. The development of an appropriate rehabilitation model is still necessary. This study aims to study factors influencing limb movements in post-stroke patients.MethodsThis cross-sectional study comprised 120 ischemic stroke patients obtained by multi-stage sampling in Muang district, Phitsanulok province. The data were collected using questionnaires with Cronbach’s alpha coefficient of 0.89. The ability to move the muscles of the limbs of the patients was assessed using the motor power assessment form, and binary logistic regression statistics analyzed the factors influencing limb movements.ResultData analysis shows that 76% of the stroke patients were female, 39.3% aged 61–70 years had a mean of 62 years and a standard deviation (S.D.) of 8.9, 4.6% of stroke patients had a duration of illness of 6–12 months, and 94.2% had a caregiver. 53.1% received rehabilitation once a week, and 92.5% received Thai massage. Thai traditional medicine utilization methods consist of Thai massage, herbal compresses, herbal steam, and taking herbal medicines. There are two factors influencing the ability to move the limb muscles of stroke patients as follows: (1) the massage with the Thai traditional medicine rehabilitation method (Adj OR = 28.917, p-value = 0.006) and (2) the number of rehabilitation sessions per week (Adj OR = 2.465, p-value < 0.001). These two variables explain the variance of regaining limb movement among post-stroke patients of 42.5% at a significance level of 0.05. In this analysis, the predictive accuracy was 70%.ConclusionRehabilitation using Thai massage, together with the number of rehabilitation sessions per week, influenced the ability of limb movement in post-stroke patients. In other words, increasing the number of rehabilitation times per week and using Thai massage in rehabilitation will help stroke patients move their limbs better.

Re- Infection Rate of Opisthorchis Viverrini Five Years After Treatment with Praziquantel in High-Risk Area: A Community-Based Study.

Opisthorchis viverrini (OV) is a significant public health problem in Thailand, and OV reinfection poses a serious risk of cholangiocarcinoma with little evidence of a decrease. While numerous studies have explored OV reinfection and prevalence, most have been limited to short study period. Therefore, there is a need for long-term investigations to gather sufficient evidence. This study aimed to access the current status of re-infection rates in high- risk areas and to determine associations between factors of and re-infection of OV at 5 years after treatment with praziquantel. In total, this study included 457 participants from a cohort study. Each participant was required to answer a questionnaire and undergo stool examination using the formalin ethyl acetate concentration technique. Data were analyzed using descriptive statistics and multiple logistic regression. Out of the total 457 participants, 418 (91.5%) successfully completed the questionnaires and underwent stool examinations. Among the participants, 10.8% showed re-infection with OV. Using multivariate analysis, factors significantly associated with reinfection OV included yearly income (OR adj = 2.14, 95%CI = 1.11- 4.12, p-value = 0.022) and past stool examination five years (OR adj = 2.47, 95%CI = 1.13-5.43, p-value = 0.023), respectively. Subjects who frequently experience OV reinfection should undergo CCA screening by experts while closely monitoring their raw fish consumption behavior. Moreover, it is essential to implement comprehensive programs aimed at promoting behavioral changes and provide preventive education, with a specific focus on high epidemic areas, to discourage the consumption of raw fish.

LEAFLETS AND EXTRA–LEAFLETS HYPOATTENUATED LESIONS FOLLOWING TAVR

Abstract Introduction Subclinical leaflets thrombosis is a condition diagnosed with multi–detector computer tomography (MDCT) characterized by a meniscal–shaped hypoattenuated lesion of one or more leaflets. Transcatheter aortic self–expandable valves are commonly manufactured with pliable pericardium over a nitinol frame that forms the leaflets and the extra–leaflets components, such as the valve skirt. Little is known about extra–leaflets hypoattenuated lesions localization, including the anatomic sinus level. Methods This was an ambi–directional study. Fifty patients underwent MDCT at follow–up. Results At mean follow–up was of 12 months, hypoattenuated leaflet lesion with mild to severe restricted movement was detected in 8 individuals (16%); anatomic sinus lesion was identified in 9 patients (18%) with higher prevalence in the non–coronary sinus (16%); subvalvular lesion with a variable extension toward the valve inflow, was diagnosed in 8 patients (16%). In 4 patients (8%) the anatomic sinus thrombus was ‘in overlap’ with the leaflet thrombus; in 3 patients (6%) was in continuity with the subvalvular frame thrombus. Bicuspid valve was the only independent predictor associated with hypoattenuated lesions (adj OR 8.25 (95% CI: 1.38, 49.21), p=0.02). Conclusions This study demonstrated that hypoattenuated lesions could be identified not only at leaflet, but also at subvalvular and anatomic sinus level. The clinical relevance of such lesions remains uncertain.

OA41 Exploring patterns of patient engagement with electronic patient reported outcome measures in inflammatory arthritis using latent class growth modelling

Abstract Background/Aims Routine collection of electronic patient reported outcome measures (ePROMs) can facilitate dynamic disease activity monitoring in patients with inflammatory arthritis (IA). In a real-world cohort of patients with IA, we describe patient characteristics associated with ever engaging with ePROMs, evaluate whether there are distinct groups of patients with similar engagement trajectories over time and identify patient characteristics associated with these groups. Methods We conducted a prospective observational study based on routinely collected data from a remote monitoring platform (RMP) at Guy’s and St Thomas’ NHS Foundation Trust in London, UK, between 18 December 2018 and 15 August 2022. Patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (AxSpA) were sent text message requests to complete 4-weekly disease specific PROMs. A patient was defined as an engager if they completed at least one PROM episode during the study period of 68 weeks. Logistic regression (LR) was used to identify associations between baseline characteristics and any PROM engagement. Latent class growth modelling (LCGM) was used to determine PROM engagement trajectories, with multinomial LR exploring baseline characteristic associations with latent trajectory class membership. Results Of 1,203 patients on RMP in the study period, 1,129 met the inclusion criteria, of which 91.5% (95% CI 89.7% - 93.0%) completed at least one PROM. Mean age was 49 years and 64% were female. 60% had RA, 24.4% had PsA and 15.7% had AxSpA. Overall engagement was relatively high throughout, with continued engagement &amp;gt;60% over the remaining 68 weeks. Older patients (adj OR 0.98, 95% CI 0.96 - 0.99), those from more deprived areas (adj OR 0.80, 95% CI 0.68 - 0.96) and those who attended &amp;lt;80% of their outpatient visits in the preceding 3 years (adj OR 0.48, 95% CI 0.26 - 0.89) were less likely to complete a PROM. Four latent trajectory classes were identified: consistent engagers (38.1%), high-variable engagers (24.3%), low-variable engagers (19.5%) and never &amp; dis-engagers (18.1%), with a mean (SD) overall response rate per class of 96.5% (7.1), 74.1% (12.1), 35.6% (13.8) and 7.5% (12.0) respectively. Compared to the consistent engager class, the two variable engager classes were significantly more likely to be younger at baseline, whilst the never &amp; dis-engager class was more likely to be from a deprived area. Having an IA type of PsA and previous clinic non-attendance was associated with membership of the three lower engaging classes. Conclusion We have described key patient characteristics that influence engagement with ePROMs in a real-world cohort of patients with IA, and patterns of engagement over time. Overall engagement was very high with &amp;gt;90% of patients enrolled engaging with PROM completion. There is still scepticism among clinicians about remote monitoring’s ability to work, and our findings should be reassuring: patients do engage with ePROMs over time. Disclosure N. Arumalla: None. Z.

Sexually transmitted infections: Prevalence and clinical outcomes among pregnant women in Western Sydney.

We report the prevalence, characteristics and clinical outcomes of women with sexually transmitted infections (STIs) in pregnancy in the Western Sydney Local Health District (WSLHD) serving a large culturally and socio-economically diverse community in New South Wales (NSW), Australia, over the last 10 years. A retrospective cohort study of all pregnant women booked for antenatal care at three hospitals in WSLHD between September 2012 and August 2022 inclusive. Characteristics and birth outcomes associated with STIs diagnosed in pregnancy (chlamydia, gonorrhea, and syphilis) are reported using multivariable logistic regression adjusting for relevant confounders. During 2012-2022, there were 102 905 births and 451 women (0.44%) with an STI diagnosis during pregnancy. The number of women with a history of chlamydia prior to their current pregnancy has increased over the last 10 years (P < 0.001). STIs in pregnancy were more common in younger women aged <20 years (adjusted odds ratio [aOR] 7.30, 95% confidence interval [CI] 5.04-10.57), 20-24 years (aOR 3.12, 95% CI 2.46-3.96), and >40 years (adj OR 1.67, 95% CI 1.07-2.59), in women with body mass index >30 (aOR 1.73, 95%CI 1.37-2.19), and those who smoked (aOR 2.24, 95% CI 1.71-2.94) and consumed alcohol (aOR 3.14, 95% CI 1.88-5.23) and illicit drugs (aOR 2.10, 95% CI 1.31-3.36). STIs in pregnancy were borderline associated with stillbirth (aOR 2.19 95% CI 0.90-5.36) but did not have a significant impact on preterm birth (aOR 1.21, 95% CI 0.87-1.68), admission to neonatal intensive care unit (NICU) (aOR 1.02, 95% CI 0.77-1.34), or having a small-for-gestational-age (SGA) baby (aOR 0.97, 95% CI 0.74-1.27). Sociodemographic factors such as age, weight, smoking, and alcohol and drug use, were associated with the STI incidence in pregnancy. While the latter did not have an impact on preterm birth, NICU admission, and SGA in our cohort, there was a borderline association with stillbirth. Future research should identify barriers and facilitators to testing in a multicultural population and understanding the drivers of higher rates of STIs in certain population groups.

Uptake and 4-week quit rates from an opt-out co-located smoking cessation service delivered alongside community-based low-dose computed tomography screening within the Yorkshire Lung Screening Trial.

Up to 50% of those attending for low-dose computed tomography screening for lung cancer continue to smoke and co-delivery of smoking cessation services alongside screening may maximise clinical benefit. Here we present data from an opt-out co-located smoking cessation service delivered alongside the Yorkshire Lung Screening Trial (YLST). Eligible YLST participants were offered an immediate consultation with a smoking cessation practitioner (SCP) at their screening visit with ongoing smoking cessation support over subsequent weeks. Of 2150 eligible participants, 1905 (89%) accepted the offer of an SCP consultation during their initial visit, with 1609 (75%) receiving ongoing smoking cessation support over subsequent weeks. Uptake of ongoing support was not associated with age, ethnicity, deprivation or educational level in multivariable analyses, although men were less likely to engage (adjusted OR (ORadj) 0.71, 95% CI 0.56-0.89). Uptake was higher in those with higher nicotine dependency, motivation to stop smoking and self-efficacy for quitting. Overall, 323 participants self-reported quitting at 4 weeks (15.0% of the eligible population); 266 were validated by exhaled carbon monoxide (12.4%). Multivariable analyses of eligible smokers suggested 4-week quitting was more likely in men (ORadj 1.43, 95% CI 1.11-1.84), those with higher motivation to quit and previous quit attempts, while those with a stronger smoking habit in terms of cigarettes per day were less likely to quit. There was high uptake for co-located opt-out smoking cessation support across a wide range of participant demographics. Protected funding for integrated smoking cessation services should be considered to maximise programme equity and benefit.

Prognostic impact of main pulmonary artery to ascending aorta diameter ratio in patients with severe aortic stenosis underwent transcatheter aortic valve implantation.

Pulmonary hypertension (PH) and right ventricular dysfunctionare poor prognostic predictors in patients underwent transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS). The prognostic impact of the main pulmonary artery/ascending aorta diameter ratio (MPA/AOr), measured simply by computed-tomographic angiography (CTA), was investigated in this patient group. A total of 374 retrospectively evaluated patients (mean age 78.1 ± 8.4 years, 192 [51.3%]females)who underwent TAVI for severe AS were included. MPA/AOr was measured on preprocedural CTA in all patients and the effect of this measurement on the presence of PH, in-hospital and 2-year-overall long-term mortality was investigated. The presence of PH was defined as a systolic pulmonary artery pressure (sPAP) >42 mmHg measured by echocardiography. According to multivariate-logistic-regression analysis, MPA/AOr(adjusted [Adj] odds ratio [OR]: 1.188, confidence interval [CI] 95% [1.002-1.410], p = 0.048), tricuspid annular plane systolic excursion (TAPSE)(adj OR:0.736, CI 95% [0.663-0.816], p < 0.001)and left atrial diameter (adj OR:1.051, CI 95% [1.007-1.098], p = 0.024)were identified as independent predictors of PH. In addition, a statistically significant correlation was found between MPA/AOr and TAPSE (r: -0.283, p < 0.001). Furthermore, MPA/AOr was found to be an independent predictor of both in-hospital (adj OR:1.434, CI 95% [1.093-1.881], p = 0.009)and 2-year long-term (adj OR:1.518, CI 95% [1.243-1.853], p < 0.001)mortality in multivariate analysis including TAPSE, STS score and sPAP. In the 2-year Kaplan-Meier survival probability analysis, an MPA/AOr >0.86 was found to have ahazard ratioof 3.697 (95% CI: 2.341-5.840), with a log-rank p < 0.001. MPA/AOr, which can be measured simply by CTA, may be useful as an indicator of the presence of PH and poor prognosis in patients planned for TAVI for severe AS.

Home care models dedicated to COVID-19 patients: the experience of a Local Health District of Veneto Region (Italy).

During COVID-19 pandemic, health professionals have been working in an extreme uncertainty context. Affected patients needed to be cared at home as long as possible to avoid virus spreading and hospital resources saturation. The Veneto Regional Administration (North-east of Italy) released Regional guidelines about it. The Western Healthcare District of the Local Health Authority of the city of Vicenza (180,000 inhabitants) implemented a healthcare pathway following them. Aim of the study is to describe the results and outcomes of such implementation. In the implemented health care pathway, a new service called "Special Unit of continuity of care" (USCA) with physicians and nurses has been dedicated to the prise en charge at home of patients suffering from Sars-CoV-2. They were referred to the USCA by general practitioners or by hospital specialists, and managed through a daily clinical monitoring by regular home visits and phone calls, specialist consultations and therapy management. In order to prevent hospital admission, an oxygen concentrator when possible has been employed and managed at home by the members of the USCA when the oxygen saturation was below 93%. An observational retrospective study has been conducted using anonymized data from different databases: the USCA activity database (from 12/01/20 to 21/31/21), the hospital and Emergency Department discharge databases, and the "healthcare co-payments exemptions database". The latter database refers to the people excluded - because of their chronicity - from the co-payment of a list of medical exams and services. Descriptive and multivariate logistic regression analyses have been implemented. 1,419 patients suffering from Sars-CoV-2 have been cared and managed by the USCA in the considered period of time (mean 11.4 days), of whom 787 (55.5%) with at least one chronic condition (described in the above quoted "healthcare co-payments exemption database") and 261 provided with oxygen concentrator. 275 (19.4%) needed a hospital admission, 39 (2.8%) in intensive unit; 53 died during hospitalization (3.8%). Out of the 261 patients utilizing oxygen concentrator, 103 have been admitted to hospital (39.5%), 7.3% in intensive unit and 8.0% died. In implemented multivariate analyses, the use of oxygen concentrator, proxy measure of the severity of the condition, is the major determinant for the risk of hospital admission (adj OR: 3.2, CI 2.3-4.3) and of dying within 30 days (adj OR: 2.8 CI 1.5-5.1). Among the 261 patients provided with oxygen concentrator, 158 (60,5%) have been managed at home without any admission to emergency department and/or hospitalization. In an uncertain context such as COVID-19 pandemic, the already-implemented home care model has been modified by integrating the USCA physicians and nurses and specialist care networks to prevent hospitalization and the sense of isolation and abandonment of people as much as possible. Almost 1,500 patients suffering from COVID-19 have been cared for at home over 13 months by such new service with complex and multidisciplinary activities. The risk of hospitalization and death appears determined by the severity of the pathology with high and significant OR 60% of patients with oxygen concentrators who, despite an initial high hyposaturation were not hospitalized, represent, partly, the group of patients who would have been requiring hospital care in the absence of a home care pathway in a standard situation.

Access to and Timeliness of Lung Cancer Surgery, Radiation Therapy, and Systemic Therapy in New Zealand: A Universal Health Care Context.

Lung cancer is the biggest cancer killer of indigenous peoples worldwide, including Māori people in New Zealand. There is some evidence of disparities in access to lung cancer treatment between Māori and non-Māori patients, but an examination of the depth and breadth of these disparities is needed. Here, we use national-level data to examine disparities in access to surgery, radiation therapy and systemic therapy between Māori and European patients, as well as timing of treatment relative to diagnosis. We included all lung cancer registrations across New Zealand from 2007 to 2019 (N = 27,869) and compared access with treatment and the timing of treatment using national-level inpatient, outpatient, and pharmaceutical records. Māori patients with lung cancer appeared less likely to access surgery than European patients (Māori, 14%; European, 20%; adjusted odds ratio [adj OR], 0.82 [95% CI, 0.73 to 0.92]), including curative surgery (Māori, 10%; European, 16%; adj OR, 0.72 [95% CI, 0.62 to 0.84]). These differences were only partially explained by stage and comorbidity. There were no differences in access to radiation therapy or systemic therapy once adjusted for confounding by age. Although it appeared that there was a longer time from diagnosis to radiation therapy for Māori patients compared with European patients, this difference was small and requires further investigation. Our observation of differences in surgery rates between Māori and European patients with lung cancer who were not explained by stage of disease, tumor type, or comorbidity suggests that Māori patients who may be good candidates for surgery are missing out on this treatment to a greater extent than their European counterparts.

Acute blood loss anemia in hospitalized patients is associated with adverse outcomes: An analysis of the Nationwide Inpatient Sample

BackgroundAcute blood loss anemia is the most common form of anemia and often results from traumatic injuries or gastrointestinal bleeding. There are limited studies analyzing outcomes associated with acute blood loss anemia in hospitalized patients. MethodsThe Nationwide Inpatient Sample (NIS) was analyzed from 2010 to 2014 (n = 133,809). The impact of acute blood loss anemia on in-hospital mortality, length of stay (LOS), healthcare cost, and disposition was determined using regression modeling adjusted for age, gender, race, and comorbidities. ResultsHospitalized patients with acute blood loss anemia had significantly higher healthcare cost (adj OR 1.04; 95% CI: 1.04–1.05), greater lengths of stay (adj OR 1.18; 95% CI: 1.17–1.18), and were less likely to be discharged home compared to the general medical population (adj OR 0.27; 95% CI: 0.26–0.28). Acute blood loss anemia was associated with increased risk for mortality in unadjusted models (unadj 1.16; 95% CI: 1.12–1.20) but not in adjusted models (adj OR 0.91; 95% CI: 0.88–0.94). When analyzing comorbidities, a “muscle loss phenotype” had the strongest association with mortality in patients with acute blood loss anemia (adj OR 4.48; 95% CI: 4.35–4.61). The top five primary diagnostic codes associated with acute blood loss anemia were long bone fractures, GI bleeds, cardiac repair, sepsis, and OB/Gyn related causes. Sepsis had the highest association with mortality (18%, adj OR 2.59; 95% CI: 2.34–2.86) in those with acute blood loss anemia. ConclusionsAcute blood loss anemia is associated with adverse outcomes in hospitalized patients.

Medication-related burden and its association with medication adherence among elderly tuberculosis patients in Guizhou, China: a cross-sectional study.

Tuberculosis (TB) morbidity and mortality are significantly increasing in the elderly worldwide. Their optimal health outcomes are hampered by medication related burden (MRB) and poor treatment adherence. Understanding th e MRB status from patients' perspectives and its association with adherence among elderly TB patients will help achieve the End TB targets. Thus, we aimed to identify the incidence of MRB and nonadherence among elderly TB patients in Guizhou, and determine their association. A cross-sectional study was conducted in three prefectures with high TB notifications in Guizhou in 2022. The data were collected via face-to-face structured interviews. MRB was measured using the Living with Medicines Questionnaire version 3 (LMQ-3), which consists of eight domains. Nonadherence was assessed by treatment interruption, which was defined as any interruption lasting at least 1day at any time within the last 3months. A binary unconditional logistic regression model was used to determine the association between variables. Of the 405 elderly TB patients enrolled, 49.4% and 42.7% of the respondents perceived suffering from moderate and high MRB, respectively. The incidence of nonadherence among patients was 33.6%. Patients with higher scores in domain 2 (practical difficulties) [OR adj = 1.19; 95% CI (1.11-1.28)] and domain 4 (side effects burden of prescribed medications) [OR adj = 1.16; 95% CI (1.06-1.27)] were more likely to experience nonadherence. But, patients with higher scores in domain 8 (control/autonomy of medicine use) [OR adj = 0.70; 95% CI (0.61, 0.81)] were more likely to occur adherence. Patients with a high education level [OR adj = 0.29; 95% CI (0.08, 0.92)] had a decreased risk of nonadherence, but those with a living expense from a retirement salary [OR adj = 2.55; 95% CI (1.16, 5.71)] had an increased risk of nonadherence. The incidence of MRB and medication nonadherence is high among elderly TB patients in Guizhou. The significant associations between the three domains of MRB and nonadherence highlight that measuring MRB in multiple dimensions using the LMQ-3 in elderly TB patients could assist clinicians in providing patient-centered care, and multifaceted interventions targeting the identified problems should be implemented to reduce MRB and nonadherence among elderly TB patients in Guizhou.

Respiratory syncytial virus among hospitalized patients of severe acute respiratory infection in Bhutan: Cross-sectional study.

Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infections worldwide, particularly in young children. In Bhutan, respiratory disease continues to be among the top 10 diseases of morbidity for several years. This study aimed to estimate the prevalence of RSV among hospitalized patients with severe acute respiratory infection (SARI) in Bhutan. Respiratory specimens were collected from SARI patients of all ages in 2016 and 2018 following influenza surveillance guidelines. Specimens were tested for influenza and RSV, human metapneumovirus, adenovirus, and human parainfluenza virus types 1, 2, and 3 using real-time reverse-transcription polymerase chain reaction assay. Descriptive statistics were used to analyze the result in STATA 16.1. Of the 1339 SARI specimens tested, 34.8% were positive for at least one viral pathogen. RSV was detected in 18.5% of SARI cases, followed by influenza in 13.4% and other respiratory viruses in 3%. The median age of SARI cases was 3 (IQR: 0.8-21 years)years. RSV detection was higher among children aged 0-6 (Adj OR: 3.03; 95% CI: 1.7-5.39) and 7-23 months (Adj OR: 3.01; 95% CI: 1.77-5.12) compared with the children aged 5-15 years. RSV was also associated with breathing difficulty (Adj OR: 1.73; 95% CI: 1.17-2.56) and pre-existing lung disease, including asthma (Adj OR: 2.78; 95% CI: 0.99-7.8). Respiratory viruses were detected in a substantial proportion of SARI hospitalizations in Bhutan.

A Transtheoretical Model-Based Online Intervention to Improve Medication Adherence for Chinese Adults Newly Diagnosed With Type 2 Diabetes: A Mixed-Method Study.

Type 2 diabetes mellitus (T2DM) is increasing in China, with medication non-adherence being a significant contributor to uncontrolled T2DM. The Transtheoretical Model (TTM) has shown effectiveness in chronic disease management, but few studies have applied it in online interventions for T2DM medication adherence. The study aimed to develop and investigate the effects of a TTM-based online health education program on promoting positive stage of change (SOC) movement, improving self-efficacy and medication adherence, as well as reducing HbA1c levels in newly diagnosed patients with T2DM. This sequential mixed-method study was conducted from April 2023 to March 2024. Using the TTM framework, the study initially explored 32 participants' experiences with hypoglycemic medications, health information acquisition, and perspectives on online programs. Then, a quasi-experimental study design was conducted. Two communities were randomly assigned as the intervention (n = 91) and comparison (n = 98) groups, with 189 newly diagnosed middle-aged T2DM patients from various SOC. The intervention group received short videos health education and participated in WeChat group discussions, compared with usual care in the comparison group. Data were collected at baseline, 3-month, and 6-month follow-ups. The intervention group was more likely to achieve positive SOC movement (P < .001, Adj OR = 13.69 95% CI = 6.76-27.71) compared to the comparison group. The intervention group also had significantly higher mean CDMSS-11 and MMAS-8 scores at 6 months (P = .03 and <.001, respectively) and more likely to achieve clinically significant glycated Hemoglobin (HbA1c) change at 3 months (P < .001, Adj OR = 3.91, 95% CI = 1.77-8.63) and at 6 months (P < .001, Adj OR = 5.62, 95% CI = 2.70-11.69) compared to the comparison group. These findings support that applying the TTM to develop an online program could promote behavior change, improve self-efficacy and medication adherence, and could lead to better glycemic control in newly diagnosed T2DM patients.
