Association between statin therapy and long-term clinical outcomes in patients with stable coronary disease undergoing percutaneous coronary intervention

This longitudinal cohort study examined the long-term effect of statin therapy on clinical outcomes in patients undergoing percutaneous coronary intervention (PCI). A total of 1760 patients with stable coronary artery disease (CAD) were divided by receipt of statin therapy or not after index PCI. Baseline clinical characteristics, risk factors, angiographic findings, and medications after interventional procedure were assessed to compare long-term clinical outcomes between groups. Predictors for all-cause death and major adverse cardiovascular events (MACE), including myocardial infarction (MI), cardiovascular death, and repeated PCI procedures, were also analyzed. The statin therapy group had higher average serum cholesterol and more elevated low-density lipoprotein cholesterol (LDL-C) than the non-statin therapy group (189.0 ± 47.9 vs 169.3 ± 37.00 mg/dl, 117.2 ± 42.6 vs 98.7 ± 31.8 mg/dl, respectively, both P < 0.001). The non-statin group had higher rates of all-cause death and cardiovascular death compared to statin group (both P < 0.001). After adjustment for age, diabetes, and chronic kidney disease, Cox proportion hazard analysis revealed statin use significantly reduced all-cause death and repeated PCI procedure (hazard ratio: 0.53 and 0.69, respectively). Statin use seemed not reduce the hazard of cardiovascular death or MI in patients with stable CAD after PCI; however, statin therapy still was associated with reduced rates of all-cause death and repeat PCI procedure.

Clinical Outcome and 7-Day Virological Clearance in High-Risk Patients with Mild-Moderate COVID-19 Treated with Molnupiravir, Nirmatrelvir/Ritonavir, or Remdesivir.

We compared the effectiveness and virological clearance (VC) at day 7 (T7) post-treatment with molnupiravir, nirmatrelvir/ritonavir, and remdesivir in SARS-CoV-2-infected patients at high risk(HR) for clinical progression. We conducted a retrospective study enrolling HR patients with mild-to-moderate COVID-19 (Jan-Oct 2022) treated with nirmatrelvir/ritonavir or molnupiravir or 3days of remdesivir. We investigated clinical recovery at T7 (resolution of symptoms for ≥ 72h or all-cause death), VC at T7 (PCR/antigenic negative nasopharyngeal swab), and median time to VC (days from symptom onset to the first negative swab). Factors associated with VC were investigated by logistic regression. In the study, 92/376 (43.8%) patients received molnupiravir, 150/376 (24.7%) nirmatrelvir/ritonavir, and 134/376 (31.5%) remdesivir. Forty-nine (13%) patients were unvaccinated or incompletely vaccinated. Patients treated with nirmatrelvir/ritonavir were younger and presented immunodeficiencies more frequently; remdesivir was used more commonly in patients hospitalized for other diseases. A high proportion of patients obtained clinical recovery without differences among the therapies (97.5% for molnupiravir, 98.3% for nirmatrelvir/ritonavir, and 93.6% for remdesivir); 12 (3.7%) patients died. Nirmatrelvir/ritonavir was associated with a higher proportion of T7 VC and a shorter time to VC compared to molnupiravir/remdesivir, also after adjustment for age and immunodeficiency (AOR 0.445 RDV vs. NMV-r, 95% CI 0.240-0.826, p = 0.010; AOR 0.222 MNP vs. NMV-r, 95% CI 0.105-0.472, p < 0.001). SARS-COV-2 antiviral treatments are an excellent therapeutic strategy in HR patients. Nirmatrelvir/ritonavir showed a higher proportion of VC as early as 7days after treatment, confirming its likely superiority in indirect comparisons.

Fatigue by the Chalder Questionnaire and post-hemodialysis recovery in a population of predominantly African descent: The PROHEMO.

A high prevalence of fatigue and a positive association between fatigue and post-hemodialysis recovery have been reported in predominantly white populations of maintenance hemodialysis (MHD) patients. The present study evaluates associations between self-reported fatigue by the 11-item Chalder Fatigue Questionnaire (CFQ-11) and the need for post-hemodialysis recovery in a predominantly African-descent MHD population. A total of 233 patients (94% Black or Mixed-Race) participating in the "Prospective Study of the Prognosis of Patients on Maintenance Hemodialysis" (PROHEMO), Salvador, Brazil were recruited for this cross-sectional study. The CFQ-11 was used to measure fatigue: <4 for absent or mild, ⩾4 for moderate to severe. Patients were also asked if they needed some time to recover after the hemodialysis. Logistic regression was used to estimate odds ratio (OR) of the association with adjustments for age, sex, race, educational level, economic class level, diabetes, hearth failure, and hemoglobin. Mean age was 51.5 ± 12.5 years. Moderate to severe fatigue (⩾4 points) was observed in 70.8% (165/233), and absent or mild fatigue (<4 points) in 29.2% (68/233). Compared to patients with fatigue scores <4 (20.6%), the need for post-hemodialysis recovery was 2.5 times greater in patients with fatigue scores ⩾4 (52.7%). The covariate-adjusted logistic regression OR was 4.60, 95% CI: 2.27, 9.21. This study in MHD patients of predominantly African descent supports self-reported fatigue assessed by the CFQ-11 as a relevant predictor of the need for post-hemodialysis recovery. The results offer a rationale for investigating whether interventions to prevent fatigue reduce the need of post-hemodialysis recovery.

The relationship between ambulatory arterial stiffness index and incident atrial fibrillation.

The ambulatory arterial stiffness index (AASI) is an indirect measure of blood pressure variability and arterial stiffness which are atrial fibrillation (AF) risk factors. The relationship between AASI and AF development has not been previously investigated and was the primary aim of this study. This was an observational cohort study of adults (aged 18-85 years) in sinus rhythm, who underwent 24-h ambulatory blood pressure monitoring (ABPM) for the diagnosis of hypertension or its control. Eight hundred and twenty-one patients (49% men) aged 58.7 ± 15.3 years were followed up for a median of 4.0 years (3317 patient-years). In total, 75 patients (9.1%) developed ≥1 AF episode during follow-up. The mean AASI was 0.46 ± 0.17 (median 0.46). AASI values (0.52 ± 0.16 vs. 0.45 ± 0.17; p < .001) and the proportion of AASI values above the median (65.3% vs. 48.4%; p = .005) were greater among the patients who developed AF versus those that did not respectively. AASI significantly correlated with age (r = .49; 95% confidence interval: 0.44-0.54: p < .001). On Kaplan-Meier analysis, higher baseline AASI by median, tertiles, and quartiles were all significantly associated with AF development (X2: 10.13; p < .001). On Cox regression analyses, both a 1-standard deviation increase and AASI > median were independent predictors of AF, but this relationship was no longer significant when age was included in the model. AASI is an independent predictor of AF development. However, this relationship becomes insignificant after adjustment for age which is higher correlated with AASI.

May Measurement Month 2021: an analysis of blood pressure screening results from China.

We reported findings from participants screened during the May Measurement Month 2021 in China, which aimed to raise awareness of raised blood pressure (BP), and to investigate the risk factors of BP. The study participants were adults (≥18 years), ideally in whom BP had not been measured in the previous year. Blood pressure was measured three times consecutively with 1 min intervals in the sitting position, using a validated upper-arm cuff automated BP monitor (Omron HEM-7081IT), and transmitted to a central cloud database via a smartphone app. The measurement was performed in 218 844 participants in 183 sites across 31 China provinces. The mean (standard deviation) age was 47.0 (15.7) years, and 51.8% (n = 113 466) were women. The mean systolic/diastolic BP was 120.2/77.5 mmHg. Among 57 178 (26.1%) participants with hypertension, the awareness, treatment, and control rates of hypertension were 30.4% (n = 17 354), 28.7% (n = 16 369), and 17.1% (n = 9743), respectively. After adjustment for age, sex, and use of antihypertensive medication, both systolic and diastolic BP were significantly (P ≤ 0.01) higher in current smokers (n = 22 344, +0.4/+0.7 mmHg) and with moderate (n = 4780, +1.4/+4.2 mmHg) or daily alcohol intake (n = 2427, +1.3/+2.5 mmHg). Blood pressure was lower in those reporting regular exercise (n = 32 328, -2.2/-1.4 mmHg). In addition, individuals with previous COVID-19 vaccination had lower systolic and diastolic BP (n = 88 945, -1.8/-1.5 mmHg, P ≤ 0.001). In conclusion, our study showed that long-term large-scale screening for hypertension is feasible, and there is a strong association between BP and major lifestyle factors.

Identifying modifiable risk factors to improve immigrant breast cancer screening in the United States.

1530 Background: Despite marked reductions in breast cancer mortality since 1990, recent data suggest that progress has slowed—owing in part to plateaus in breast cancer screening in underserved populations. Historically low rates of screening coupled with rising breast cancer incidence make immigrants an important population for targeted intervention. Herein, we (1) compare contemporary rates of breast cancer screening among immigrants versus US natives; and (2) identify modifiable risk factors to inform the development of interventions to improve screening among immigrants in the United States. Methods: Using data from the 2019 and 2021 National Health Interview Surveys, screening eligible female participants (ages 40-79 years old) were identified, then classified by immigrant status as defined by nativity (US native vs. foreign-born). Primary outcome was receipt of screening mammogram in the last two years. Logistic regression models examined associations between immigrant status and mammography, with and without adjustments for age, metropolitan residence, overall health status, and survey year. Sequential analysis was then used to assess the degree to which modifiable social risk factors influence the magnitude of the association between immigrant status and mammography. Results: Of 20,090 female participants included in the study, 20% were immigrants. Compared to US natives, immigrants were less likely to have received a mammogram in the last two years (67% vs. 72%, aOR [95%CI], 0.87 [0.78-0.96], p=0.006)—an effect that was most pronounced among immigrant noncitizens (57%; 0.55 [0.47-0.64], p&lt;0.001) but reversed among immigrants with US citizenship (74%; 1.14 [1.01-1.29], p=0.03). Of the factors assessed, having a usual source of care (5.73 [4.77-6.87]) or insurance (4.60 [3.74-5.67]) was associated with the greatest odds of biennial mammography, followed by educational attainment (1.38 [1.19-1.60]) and employment (1.19 [1.09-1.30]; all p&lt;0.001). While having a usual source of care or employment attenuated—but did not eliminate—the association between immigrant status and mammography (0.87 [0.78-0.96], p=0.01 and 0.89 [0.80-0.99], p=0.03, respectively), this finding was not observed upon inclusion of insurance status or education in sequential models (0.97 [0.87-1.09], p=0.6 and 1.09 [0.96-1.21], p=0.13, respectively). With respect to insurance type, Medicare Advantage (4.60 [3.74-5.67]) conferred the largest benefit, followed by private insurance (4.54 [4.00-5.26]), Medicaid (2.63 [2.20-3.14]), and Medicare (4.39 [3.53-5.46]; all p&lt;0.001). Conclusions: Breast cancer screening remains low in noncitizen immigrant populations. Targeted interventions to improve access to health insurance coverage and primary care for noncitizens may be most effective for improving rates of screening mammography among immigrants and thus warrant further investigation.

Relevance of timing intake of everolimus (EVE) combined with adjuvant endocrine therapy (ET) in patients (pts) with high-risk early breast cancer: Results of a sub-study of the UCBG-UNIRAD trial.

542 Background: We reported the benefit of taking evening tamoxifen compared to morning/afternoon as adjuvant treatment for high-risk breast cancers in the UNIRAD phase III trial (NCT01805271) (1). Here, we examine the relevance of EVE timing intake in this trial. Methods: 1,277 pts with high-risk HR+/ HER2- primary BC were randomly assigned to adjuvant ET with placebo or EVE (1). Patients prospectively reported in a diary the daily timing for ET and EVE intake among four 6-h slots (06:00 to 11:59 (morning), 12:00 to 17:59 (afternoon), 18:00 to 23:59 (evening), or 24:00 to 05:59 (night). The association between EVE, ET timing and disease-free survival (DFS) was a prespecified secondary endpoint of the trial. Results: EVE timing was recorded by 513 of 632 patients (81.2%). Patients declaring EVE intake in the morning (n= 248, 48 %) or in the afternoon (n=52, 10%) were older than those declaring evening (n=207, 40 %) or night (n=6,1%) intakes ( p&lt;0.001). They were more likely to be postmenopausal (p=0.001) and to take AI rather than tamoxifen (p = 0.03). Only 17 patients (3%) changed EVE intake timing throughout the study. EVE intake dialy times were binned into 2 categories for analyses: morning/afternoon group (n=300) and evening/night group (n = 213). The patients who took morning/afternoon EVE chose another timing for ET in 38% of the cases compared to 17.1% in evening/Night EVE group (p&lt;0.01). The timing of EVE intake was not significantly associated with definitive EVE withdrawal ( p=0.62) in the whole population. Time to EVE withdrawal was significantly longer in the patients taking tamoxifen rather than AI (17.2 vs 10.9 months, p = 0.0047). Prolonged duration of EVE treatment was associated with evening/night intakes of both EVE and tamoxifen, compared to other drug timing modalities (p = 0.04). With a median follow-up of 85months, 15 patients relapsed locally (3%), 55 developed metastases (11%), 36 patients died (7%). Overall, EVE intake timing was not associated with DFS (HR=0.84 [95% CI, 0.53 - 1.35], p=0.4). There was a significant interaction between EVE timing intake and ET type ( P interaction= 0.001). Patients on evening/night EVE combined with tamoxifen had a reduced likelihood of relapse compared to those taking morning/afternoon EVE (HR = 0.17 [0.05- 0.59], p = 0.005). In contrast, no significant EVE effect was found in the AI group (HR = 1.56 [0.92 2.64], p = 0.1). Evening/Night intake of EVE plus tamoxifen was independently associated with DFS (HR 0.13 [0.03-0.6], p = 0.002) after adjustment for age, nodal status, tumor size, ET timing intake, and EVE dose (2.5, 5 or 10 mg). Conclusions: These exploratory results are consistent with a role of circadian rhythm in the efficacy of EVE when given with tamoxifen in pts with high risk early breast cancer. 1. S.

Association between modified frailty index and postoperative delirium in patients after cardiac surgery: A cohort study of 2080 older adults.

To evaluate the association between frailty and postoperative delirium (POD) in elderly cardiac surgery patients. A retrospective study was conducted of older patients admitted to the intensive care unit after cardiac surgery at a tertiary academic medical center in Boston from 2008 to 2019. Frailty was measured using the Modified Frailty Index (MFI), which categorized patients into frail (MFI ≥3) and non-frail (MFI = 0-2) groups. Delirium was identified using the confusion assessment method for the intensive care unit and nursing notes. Logistic regression models were used to examine the association between frailty and POD, and odds ratios (OR) with 95% confidence intervals (CI) were calculated. Of the 2080 patients included (median age approximately 74 years, 30.9% female), 614 were frail and 1466 were non-frail. The incidence of delirium was significantly higher in the frail group (29.2% vs. 16.4%, p < 0.05). After adjustment for age, sex, race, marital status, Acute Physiology Score III (APSIII), sequential organ failure assessment (SOFA), albumin, creatinine, hemoglobin, white blood cell count, type of surgery, alcohol use, smoking, cerebrovascular disease, use of benzodiazepines, and mechanical ventilation, multivariate logistic regression indicated a significantly increased risk of delirium in frail patients (adjusted OR: 1.61, 95% CI: 1.23-2.10, p < 0.001, E-value: 1.85). Frailty is an independent risk factor for POD in older patients after cardiac surgery. Further research should focus on frailty assessment and tailored interventions to improve outcomes.

Impact of insomnia on ovarian cancer risk and survival: a Mendelian randomization study

Insomnia is the most common sleep disorder in patients with epithelial ovarian cancer (EOC). We investigated the causal association between genetically predicted insomnia and EOC risk and survival through a two-sample Mendelian randomization (MR) study. Insomnia was proxied using genetic variants identified in a genome-wide association study (GWAS) meta-analysis of UK Biobank and 23andMe. Using genetic associations with EOC risk and overall survival from the Ovarian Cancer Association Consortium (OCAC) GWAS in 66,450 women (over 11,000 cases with clinical follow-up), we performed Iterative Mendelian Randomization and Pleiotropy (IMRP) analysis followed by a set of sensitivity analyses. Genetic associations with survival and response to treatment in ovarian cancer study of The Cancer Genome Atlas (TCGA) were estimated controlling for chemotherapy and clinical factors. Insomnia was associated with higher risk of endometrioid EOC (OR=1.60, 95% CI 1.05-2.45) and lower risk of high-grade serous EOC (HGSOC) and clear cell EOC (OR=0.79 and 0.48, 95% CI 0.63-1.00 and 0.27-0.86, respectively). In survival analysis, insomnia was associated with shorter survival of invasive EOC (OR=1.45, 95% CI 1.13-1.87) and HGSOC (OR=1.4, 95% CI 1.04-1.89), which was attenuated after adjustment for body mass index and reproductive age. Insomnia was associated with reduced survival in TCGA HGSOC cases who received standard chemotherapy (OR=2.48, 95% CI 1.13-5.42), but was attenuated after adjustment for clinical factors. This study supports the impact of insomnia on EOC risk and survival, suggesting treatments targeting insomnia could be pivotal for prevention and improving patient survival.

Dietary Intake, Diet Diversity, and Weight Status of Children With Food Allergy

BackgroundAdoption of allergen avoidance diets may increase the risk of nutritional deficiencies and affect growth in children with food allergy (FA). How these dietary restrictions have an impact on diet diversity, a health-promoting eating behavior, remains unclear. ObjectiveTo evaluate diet diversity, dietary intake, and weight status of children with FA. DesignObservational study. Participants/settingOne hundred children with immunoglobulin E (IgE)-mediated milk, egg, or nut FA or multiple FAs and 60 children with perennial respiratory allergies (RA) matched as controls, aged 3 to 18 years, were consecutively recruited into the study. Main outcome measuresDietary intake and diet diversity (number of different foods consumed/day) were assessed through four 24-hour recalls. Weight status (underweight, healthy weight, overweight, or obesity) was also evaluated. Statistical analyses performedChi-squared test and two-sample independent t test were used to test differences between groups. Adjustment for sex, age, and energy intake was made using linear regression. ResultsThe percentage of underweight was higher in children with FA (19.6%) compared with children in the control group (5.1%). Children with FA compared with children in the control group consumed more servings of meat (1.7, 95% confidence interval [CI], 1.6, 1.9 vs. 1.5, 95%CI, 1.3, 1.7 servings/day [Padj = 0.031]). No difference was observed in the diet diversity between the two groups (11–12 different foods/day). Within the FA group, children with allergy to milk proteins had lower energy intake from protein, lower intake of calcium, lower consumption of commercially prepared sweets, and higher consumption of eggs, compared with children with nut or egg allergy, but no difference in diet diversity was observed. ConclusionsDiet diversity did not differ between children with FA and children with no FA, despite some differences in the intake from specific food groups. However, the higher percentage of underweight in children with FA suggests the need for targeted nutrition intervention as early as possible after FA diagnosis.

Critical care therapy use after radical cystectomy in patients with non-metastatic bladder cancer

PurposeTo assess critical care therapy use in patients with non-metastatic bladder cancer undergoing radical cystectomy. MethodsUsing the National Inpatient Sample (2000-2019), we identified non-metastatic bladder cancer patients undergoing radical cystectomy. Study endpoints consisted of critical care therapy use, defined as total parenteral nutrition, invasive mechanical ventilation, dialysis, percutaneous endoscopic gastrostomy tube insertion, tracheostomy, and in-hospital mortality. Estimated annual percentage changes (EAPC) and multivariable logistic regression models were used. ResultsOf 25,535 patients, 3,091 (12.1%) received critical care therapy. Critical care therapy use decreased from 13.1 in 2000 to 5.9% in 2019 (EAPC -2.4; p=0.005), and in-hospital mortality also decreased from 3.4 to 0.7% (EAPC -4.2%; p<0.001). Older (≥80 years: odds ratio [OR] 1.91; p<0.001, and 60-79 years OR 1.41; p<0.001) and sicker patients (Charlson comorbidity index [CCI] ≥3: OR 3.16; p<0.001; CCI 1-2 OR 1.89; p<0.001) were more likely to receive critical care therapy. Conversely, minimally-invasive surgical approach (OR 0.66; p=0.01) and teaching hospital status (OR 0.70; p=0.008) independently predicted lower critical care therapy use. The same risk factors were identified for in-hospital mortality. ConclusionsCritical care therapy use in radical cystectomy patients decreased from 13.1 in 2000 to 5.9% in 2019 and so did in-hospital mortality (3.4 to 0.7%). Of all critical care therapy determinants, CCI ≥3 (OR 3.2) represented the strongest followed by octogenarian age (OR 1.9). Even after adjustment for patient age and comorbidities, minimally-invasive surgical approach and teaching hospital status were associated with lower critical care therapy use, and lower in-hospital mortality.

Treatment outcomes and survival of patients with breast cancer aged 75 and older: A comparative study using propensity score-adjusted analysis.

e13763 Background: With an aging society, the incidence of breast cancer among elderly patients is expected to rise. We aimed to explore treatment outcomes in breast cancer patients aged 75 and older at our institution. The lack of consensus on whether adjuvant therapy for elderly breast cancer patients should mimic that for younger patients prompted our investigation. Methods: We conducted a comparative study using data from 1553 breast cancer surgery cases (stage 0-3) treated between April 2007 and August 2021. Patients were divided into two groups: those aged 75 and older (n=184) and those aged 74 and younger (n=1369). Variables investigated included mean age, tumor size, stage, and subtype; surgical procedures and adjuvant therapies; overall survival (OS); and OS in the 75 and older group, considering the presence or absence of hormone therapy, and propensity score-adjusted OS. Results: Comparing the group aged 74 and younger with the group aged 75 and older revealed: Mean age: (55.5 years vs. 79.6 years), tumor size: (2.4 cm vs. 2.3 cm), stage (0/1/2/3) (%): (7.3/43.1/44.1/4/6 vs. 7.6/43.4/43.4/5.7), subtype (Luminal A/Luminal B/TN/HER2) (%): (60.0/16.7/11.3/7.9 vs. 63.5/10.7/15.7/5.7). Except for age, no significant differences were observed. Mastectomy (%): 45.9 vs. 50.8, axillary lymph node dissection (%): 33 vs. 22.3, adjuvant therapy (%): 93.2 vs. 65.7, adjuvant hormone therapy (%): 90 vs. 68, adjuvant chemotherapy (%): 68 vs. 14. The group aged 75 and older received significantly less adjuvant hormone therapy and chemotherapy. Kaplan-Meier 10-year OS rates: 90.3% vs. 77.5%, showing a trend toward lower survival in the group aged 75 and older, albeit not statistically significant. No significant differences were found in overall survival rates by subtype. In the group aged 75 and older, hormone therapy was omitted in 44.6% and administered in 55.4%, resulting in a significant difference in 10-year OS rates (63.5% vs. 84.7%). Following propensity score adjustment for age, stage, and subtype, the hormone therapy-free group exhibited a higher 10-year OS rate of 100%, in contrast to 84.7% in the hormone therapy group. Conclusions: Breast cancer cases in patients aged 75 and older show similar biological characteristics to those aged 74 and younger. The absence of adjuvant therapy does not impact OS, even though elderly patients aged 75 and older are less likely to receive adjuvant hormone therapy and chemotherapy.

The relationship between serum 25-hydroxy vitamin D status and hypertension in Syrian population: retrospective cohort study

Introduction: Vitamin D is a liposoluble steroid hormone that plays a crucial role in the maintenance of bone metabolism and calcium homoeostasis. Many studies on the effects of vitamin D on general health have been significantly increased, driven by new findings concerning the systemic and extraskeletal effects of this hormone. This study was performed to determine whether low levels of vitamin D were associated with hypertension in Syrian people. Materials and methods: This retrospective cohort study consisted of 207 subjects, including 83 (40.1%) patients suffering from essential hypertension and 124 (59.9%) patients with normal blood pressure. Aged older than 18 years, who was referred to the endocrinology clinic from September 2022 to September 2023. The data were analysed by using SPSS (version 25). Logistic regression analyses were performed with adjustments for age, sex, and waist circumference. Results: Hypertension rates were 73%, 20%, and 5% in 25-hydroxyvitamin D groups less than 12 ng/ml, 12–20 ng/mL, and greater than or equal to 20 ng/ml, respectively. Odds ratios (95% CIs) for hypertension adjusting for age, sex, and waist circumference were 178.6 (30.5_1045.6), 5.13 (0.9_26.5) for 25-hydroxyvitamin D levels less than 12 ng/ml, and 12–20 ng/ml, respectively, compared with the greater than or equal to 20 ng/ml group. Conclusions: This study has shown a high prevalence of low vitamin D levels (25OHVD/20 ng/ml) among a sample of Syrian people (78.3%). The lowest 25OHVD group was associated with a higher prevalence of hypertension, which refers to an adverse association between vitamin D level and essential hypertension. Further research is needed to confirm this relationship.

Mother's own milk and bronchopulmonary dysplasia in appropriate for gestational age preterm infants.

To evaluate the association between mother's own milk (MOM) and bronchopulmonary dysplasia (BPD) in appropriate for gestational age (AGA) preterm infants <32 weeks. Clinical data of AGA preterm infants (24+0/7-31+6/7 weeks) were reviewed. Infants with ≥66% of cumulative prescribed enteral volumes as MOM from birth to 36 weeks were allocated to the high provision of MOM group (H-MOM), whereas those with <66% were assigned to the low provision of MOM group (L-MOM). Multiple regressions were used to assess the association of H-MOM with BPD and oxygen saturation to fraction inspired oxygen ratio (SFR) at 36 weeks. A total of 1041 infants met the inclusion criteria, with a median provision of cumulative enteral nutrition volumes of 5721 (IQR 2616) mL/kg. Among them, 517 (49.7%) were H-MOM and 524 (50.3%) L-MOM infants. H-MOM showed a reduction in the incidence of BPD to 31.6% compared to L-MOM infants. H-MOM had a lower risk of BPD than L-MOM infants after the adjustment for gestational age, sex, cesarean section, mean SFR at the first hours of life, surfactant administration, patent ductus arteriosus, sepsis, prolonged ventilatory supports/oxygen exposure, and cumulative energy intakes from birth to 36 weeks [aOR: 0.613, p = 0.047]. H-MOM was also associated with a lower risk of SFR in the first quartile at 36 weeks [aOR: 0.616, p = 0.028] than L-MOM. A high provision (≥66%) of enteral volume as MOM from birth to 36 weeks is associated with a reduced risk of both BPD and low SFR at 36 weeks in AGA preterm infants <32 weeks.

Circulating levels of amyloid-beta (1-40) peptide associate with cardiometabolic traits and risk for metabolic dysfunction-associated steatotic liver disease

Abstract Funding Acknowledgements None. Background and Aims The ageing-associated amyloid-beta 1-40 peptide (Αbeta40) has recently emerged as a blood-based biomarker of cardiovascular disease (CVD). Its levels predict future cardiovascular death and major adverse cardiovascular events in patients with established CVD. The value of Abeta40 in patients with metabolic syndrome who do not concomitantly have clinically overt CVD or other end-organ damage remains poorly understood. At the present study we investigated the value of plasma Αbeta40 in patients with pre- or established metabolic syndrome who are at risk for metabolic dysfunction-associated steatotic liver disease (MASLD). Methods Αbeta40 was measured in plasma by enzyme-linked immunosorbent assay and cardiometabolic traits were determined in a mixed population (n=888) of patients with established (n=243) and pre- or without metabolic syndrome (n=645) who did not have clinical signs of established cardiometabolic disease. The endpoint of the study was the association of Abeta40 with cardiometabolic indices and risk (BARD score) for MASLD. Odds ratio (OR) was calculated by ordinal regression analysis for the increasing incidence of metabolic syndrome components per increasing Abeta40 (1-SD) after adjustment for age, sex, smoking status and hyperlipidemia. Results Abeta40 levels are associated with the presence of metabolic syndrome and with higher odds for increasing incidence of metabolic syndrome components (prediabetes, low HDL-C levels, high triglyceride levels, increased waist circumference and high-risk for MASLD) after adjustment for sex, age, smoking status, hypertension and dyslipidemia. Increased Abeta40 plasma levels were associated with decreased HDL-C levels and increased triglyceride levels after adjustment for traditional cardiovascular risk factors (age, sex, smoking status, hypertension and hyperlipidemia). Among the total population (n=888), we identified n=473 subjects with increased MASLD risk if any of the following was present: hepatic steatosis index≥36 or fatty liver index≥60 or Fib-4 index≥2.67 or NAFLD score≥0.675. Among patients with high-risk for MASLD, patients with increased BARD score had significantly higher Abeta40 levels (median Abeta40 concentration in patients with BARD score≥2 vs. patients with BARD score&amp;lt;2: 54.9 pg/ml (IQR=38.25) vs. 41.9 pg/m (IQR=30.35), P=0.012). Increased Abeta40 levels were associated with increased odds for AST/ALT≥0.8 ratio (OR:1.017, 95% CI: 1.006-1.028, P=0.003) and increased odds for BARD score≥2 after adjustment for age, sex, smoking status, hypertension and hyperlipidemia. Conclusion Our findings suggest that Abeta40 peptide is associated with cardiometabolic traits and risk for MASLD. Whether Abeta40 may emerge as an early cardiometabolic prognostic biomarker, future longitudinal studies are warranted to determine the prognostic value of Abeta40 for the development of cardiometabolic diseases in patients with metabolic syndrome.

Serum Magnesium Levels Are Negatively Associated with Obesity and Abdominal Obesity in Type 2 Diabetes Mellitus: A Real-World Study.

There remains controversy over the relationship between serum magnesium levels and obesity in type 2 diabetes mellitus (T2DM). Therefore, the aim of this study was to assess whether there is any association of serum magnesium levels with obesity and abdominal obesity in T2DM. This cross-sectional, real-world study was conducted in 8,010 patients with T2DM, which were stratified into quintiles according to serum magnesium levels. The clinical characteristics and the prevalence of obesity and abdominal obesity were compared across serum magnesium quintiles in T2DM. Regression analyses were used to evaluate the relationship of serum magnesium with obesity and abdominal obesity in T2DM (clinical trial registration number: ChiCTR1800015893). After adjustment for age, sex, and duration of diabetes, the prevalence of obesity and abdominal obesity was significantly declined across magnesium quintiles (obesity: 51.3%, 50.8%, 48.9%, 45.3%, and 43.8%, respectively, P<0.001 for trend; abdominal obesity: 71.5%, 70.5%, 68.2%, 66.4%, and 64.5%, respectively, P=0.001 for trend). After controlling for confounders, there were clearly negative associations of serum magnesium levels and quintiles with obesity and abdominal obesity in T2DM. Moreover, C-reactive protein partly mediates the effect of serum magnesium on obesity and abdominal obesity (P=0.016 and P=0.004, respectively). The significantly negative relationship between serum magnesium and the risk of obesity and abdominal obesity was observed in T2DM. Furthermore, the independently negative association of serum magnesium with obesity may be explained by its anti-inflammatory functions. Serum magnesium levels may be applied to assess the risk of obesity and abdominal obesity in T2DM.

Endovascular treatment of stroke in the late time window with large vessel occlusion using the ASPECTS as an imaging screening criterion

To assess the Alberta Stroke Program Early CT Score (ASPECTS) screening tool for effectiveness in endovascular treatment of late time window stroke with large vessel occlusion. A retrospective analysis was performed of individuals administered endovascular treatment in our neurology department between 2016 and 2020 for ischemic stroke induced by acute large vessel occlusion in the anterior circulation and ASPECTS ≥ 6. Detailed baseline and endovascular treatment data were collected. Patients were assigned to 2 groups based on stroke onset time, including the 0–6 h (treated within 6 h of stroke onset) and 6–24 h (earlier/unknown time of onset, up to 24 h from the last time of appearing normal) groups. Both groups were compared for baseline information, revascularization rates, symptomatic intracranial hemorrhage, and 90-day functional independence. Totally 221 individuals were enrolled. The 0–6 h and 6–24 h groups had 129 and 92 patients, respectively, whose median ages were 64 and 63 years, respectively. Both groups were similar in previous medical history, NIHSS score at onset, lesion location and surgical complications. The 6–24 h group had elevated intracranial atherosclerotic stenosis (48.9 vs. 33.3%, P = 0.020) and revascularization (96.7 vs. 86.8%, P = 0.011) rates versus the 6–24 h group. Upon adjustment for age, sex, National Institutes of Health Stroke Scale, ASPECTS, Intracranial atherosclerosis, intraoperative tirofiban, stent detachment, successful recanalization, and symptomatic intracranial hemorrhage, the 0-6 h group had a higher rate of individuals achieving functional independence (mRS score of 0–2; 52.7 vs. 47.8%, OR = 0.242 [0.070–0.833], P = 0.024). However, the rates of individuals with a favorable outcome (mRS scores of 0–3) were similar in both groups (66.7 vs. 69.6%; OR = 0.564 [0.140–2.266], P = 0.419) as well as 90-d mortality (OR = 0.889 [0.170–4.660], P = 0.889). The ASPECTS is effective for screening individuals for endovascular treatment of stroke in the late time window with large vessel occlusion. The ASPECTS should be considered a simple and practical patient screening strategy for stroke centers without multimodal imaging evaluation.

Link between parental myopia and early-onset high myopia: Insights from a clinical retrospective analysis.

Genetic aetiology is suspected in the development of early-onset high myopia (spherical equivalent refractive error [SER] ≤-6.00 D at ≤6 years of age), considering that the role of environmental factors in inducing high myopia is improbable at an early age. Therefore, we aimed to understand if early-onset high myopia is associated with parental myopia in a clinical setting. A retrospective study was conducted in which information about demographics, age of apparent onset of myopia, refractive error, axial length, number of myopic parents, time spent outdoors and time spent on near-work was obtained from electronic medical records (EMR). It included 195 myopic individuals categorised into (1) Early-onset high myopes (EOHM): SER ≤ -6.00 D with age of presentation ≤6 years, (2) Early-onset low myopes (EOLM): SER > -6.00 D with age of apparent onset ≤6 years, (3) Late-onset high myopes (LOHM): SER ≤ -6.00 D with age of presentation and age of apparent onset >6 years and (4) Late-onset low myopes (LOLM): SER > -6.00 D with age of apparent onset >6 years. Overall, 63% of individuals were found to have parental myopia. The proportion of individuals with EOHM, EOLM, LOHM and LOLM with parental myopia was 57%, 74%, 53% and 64%, respectively. After adjustment for age, gender and environmental factors, the odds of development of EOHM (Odds ratio: 0.78, 95% confidence interval: 0.25-2.48), EOLM (1.54, 0.65-3.67) or LOHM (0.70, 0.30-1.65) were similar in the presence of myopic parents, when compared with LOLM. The SER and axial length did not differ based on the number of myopic parents in any of these categories. This retrospective analysis reveals that the presence of parental myopia, which was self-reported, did not induce additional risk for early-onset high myopia.

Long-term patient outcome is affected by deep venous thrombosis after Achilles tendon rupture repair.

The aim of the study was to examine the impact of a deep venous thrombosis (DVT) on patient outcomes 3 years after Achilles tendon rupture (ATR) repair and if there were continued improvements between 1 and 3 years after surgery. A secondary aim was to determine risk factors associated with impaired patient outcomes in the long term. This cohort study consisted of 181 ATR-repaired patients, from two large randomized clinical trials, who attended a 3-year follow-up evaluation. Patients were postoperatively randomized to two different weight-bearing interventions compared with immobilization in a below-knee plaster cast for 2 weeks. During immobilization, screening for DVT was performed with Doppler ultrasound. At 1 and 3 years postoperatively, functional- and patient-reported outcomes were evaluated by the validated heel-rise test and self-reported questionnaire, Achilles tendon Total Rupture Score (ATRS). In total, 76 out of 181 (42%) patients exhibited a DVT at the 2- or 6-week screening after ATR surgery. Suffering from a DVT during immobilization resulted at 3 years in a worse limb symmetry index (LSI) of heel-rise total work compared to patients without DVT, adjusted for age (DVT mean LSI 68% vs. no DVT 78%, p = 0.027). At 3 years, patients with a DVT during immobilization displayed lower ATRS (DVT median 88 vs. no DVT 93, p = 0.046), which was not significant after adjustment for age. However, patients with DVT exhibited an improvement in ATRS, LSI total work, and LSI maximum height between 1 and 3 years, which was not seen among patients without DVT. Independent risk factors for reduced patient functional outcomes at 3 years were older age, greater calf muscle hypotrophy, and suffering a DVT. DVT during immobilization affects patients' long-term functional outcomes 3 years after ATR repair. Clinicians should adequately address risk factors contributing to impaired patient outcomes in the long term, including calf muscle hypotrophy, DVT, and older age. Level Ⅲ.

Associations of sedentary behavior and screen time with biomarkers of inflammation and insulin resistance.

Sedentary behavior (SB) has been linked to risk factors of cardiometabolic disease, with inconsistent findings reported in the literature. We aimed to assess the associations of SB with multiple biomarkers of inflammation and insulin resistance in adults. Domain-specific SB, sitting time and moderate-to-vigorous physical activity (MVPA) were measured in 78 adults (mean ± SD 52.0 ± 10.8 y). Body fat percentage (BF%) was assessed using multi-frequency bioelectrical impedance. A blood draw assessed glucose, insulin, C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), leptin, and adiponectin. Adiponectin-leptin ratio (ALR), homeostasis model assessment of insulin resistance (HOMA-IR) and beta-cell function (HOMA-β) were calculated. Multivariable linear regression analyses, controlling for age, sex, MVPA, and BF%, were used to assess associations. After adjustment for age, sex and MVPA, total SB (7.5 ± 2.5h/day) was positively associated with leptin, insulin, HOMA-IR, HOMA-β (Standardized Beta (β) range 0.21-0.32) and negatively associated with ALR (β = -0.24, p < 0.05 for all). Similarly, total sitting time (7.2 ± 2.9h/day) was associated with TNF-α (β = 0.22) and ALR (β = -0.26). These associations were attenuated to non-significance after adjustment for BF%. Leisure screen time was detrimentally associated with IL-6 (β = 0.24), leptin (β = 0.21), insulin (β = 0.37), HOMA-IR (β = 0.37), and HOMA-β (β = 0.34), independent of age, sex and MVPA (p < 0.05 for all). Only the associations with insulin (β = 0.26), HOMA-IR (β = 0.26), and HOMA-β (β = 0.23) remained significant after further controlling BF% (p < 0.05). Self-reported SB is associated with biomarkers of inflammation and insulin resistance, independent of MVPA, and in some cases BF%.
