ABSTRACT Background Findings from existing prospective observational studies on the protective associations of flavonoid intake and the risk of Alzheimer disease and related dementias (ADRD) are inconsistent largely due to limitations of these studies. Objectives To examine the prospective relation between total and 6 classes of dietary flavonoid intake and risk of ADRD and Alzheimer disease (AD) while addressing limitations of earlier observational studies. Methods We used data from the Framingham Heart Study Offspring Cohort exams 5 through 9. Participants were ADRD-free with a valid FFQ at baseline. Flavonoid intakes were updated at each exam to represent the cumulative average intake across the 5 exams, and were expressed as percentile categories of intake (≤15th, >15th to 30th, >30th to 60th, >60th) to handle their nonlinear relation with ADRD and AD. Cox proportional hazards regression was used to estimate the HRs for the association between the flavonoid intakes and incidence of ADRD and AD. Results Over an average follow-up of 19.7 y in 2801 participants (mean baseline age = 59.1 y; 52% females), there were 193 ADRD events of which 158 were AD. After multivariate and dietary adjustments, individuals with the highest (>60th percentile) intakes of flavonols, anthocyanins, and flavonoid polymers had a lower risk of ADRD relative to individuals with the lowest intakes (≤15th percentile), with HRs (95% CI; P-trend) of 0.54 (0.32, 0.90; P = 0.003) for flavonols, 0.24 (0.15, 0.39; P < 0.001) for anthocyanins, and 0.58 (0.35, 0.94; P = 0.03) for flavonoid polymers. The same pattern of associations was seen with AD for flavonols and anthocyanins but not for flavonoid polymers. Conclusions Our findings imply that higher long-term dietary intakes of flavonoids are associated with lower risks of ADRD and AD in US adults.

Abstract Objectives Increasing evidence in animal models and humans suggests that diets high in sulfur-containing amino acids (SAA) could be associated a greater risk for type 2 diabetes (T2D). However, data from longitudinal human studies linking dietary SAA intake with T2D is lacking. The present study aimed to examine the association between long-term dietary intake of SAA including total SAAs, methionine, and cysteine and incident T2D in participants of the Framingham Heart Study (FHS). Methods Adult participants were selected from two prospective FHS cohorts: The Offspring Cohort (followed from 1991 to 2015, n = 3799) and the Third Generation Cohort (followed from 2002 to 2011, n = 4096). Individuals identified as diabetes patients before baseline, having missing diet or covariates data, or reported extreme daily energy intake were excluded. Energy-adjusted intake of dietary SAAs was calculated from responses to a 131-item food frequency questionnaire. Cox proportional hazards models were used to evaluate associations between intakes of SAAs (in quintiles) and risk of T2D in each cohort. A combined analysis was also performed pooling subjects from both cohorts. Results Overall, we documented 471 T2D events during 9–23 years of follow-up. In both cohorts, higher SAA intake was associated with a higher risk of T2D after adjustment for demographics, traditional risk factors and related nutrients. Comparing participants in the highest quintile with those in the lowest quintile of intake, adjusted hazard ratios (95% CI) were 1.98 (1.15–3.41) for total intake (P for trend = 0.04) in the Offspring cohort, and 4.37 (1.40–13.67) (P for trend = 0.01) in the Third Generation cohort. In the combination analysis of two cohorts, adjusted hazard ratios (95% CI) were 1.98 (1.23–3.21) for total intake, 2.21 (1.38–3.53) for methionine, and 1.79 (1.12–2.87) for cysteine (P for trends < 0.03). Conclusions Higher long-term SAA intake was associated with higher risk for T2D in humans, suggesting that dietary patterns emphasizing low SAA intake are protective against development of T2D.

Abstract Background and objectives Flavonoids are the most important group of polyphenols with well-known beneficial effects on health. However; the association of intake of total flavonoid or their subclasses with all-cause or cause-specific mortality is not fully understood. The present study aims to evaluate the association between intake of total flavonoid, flavonoid subclasses, and total and cause-specific mortality in a developing country. Methods A total number of 49,173 participants from the Golestan cohort study, who completed a validated food frequency questionnaire at recruitment, were followed from 2004 till 2018. Phenol-Explorer database was applied to estimate dietary intakes of total flavonoid and different flavonoid subclasses. Associations were examined using adjusted Cox proportional hazards models. Results During a mean follow-up of 10.63 years, 5104 deaths were reported. After adjusting for several potential confounders, the hazard ratios (HRs) of all-cause mortality for the highest versus the lowest quintile of dietary flavanones, flavones, isoflavonoids, and dihydrochalcones were 0.81 (95% confidence interval = 0.73–0.89), 0.83(0.76–0.92), 0.88(0.80–0.96) and 0.83(0.77–0.90), respectively. However, there was no association between total flavonoid intake or other flavonoid subclasses with all-cause mortality. In cause-specific mortality analyses, flavanones and flavones intakes were inversely associated with CVD mortality [HRs: 0.86(0.73–1.00) and 0.85(0.72–1.00)] and isoflavonoids and dihydrochalcones were the only flavonoid subclasses that showed a protective association against cancer mortality [HR: 0.82(0.68–0.98)]. Conclusion The results of our study suggest that certain subclasses of flavonoids can reduce all-cause mortality and mortality rate from CVD and cancer.

Background Persistent postoperative cognitive decline is thought to be a public health problem, but its severity may have been overestimated because of limitations in statistical methodology. This study assessed whether long-term cognitive decline occurred after surgery or illness by using an innovative approach and including participants with early Alzheimer disease to overcome some limitations. Methods In this retrospective cohort study, three groups were identified from participants tested annually at the Washington University Alzheimer's Disease Research Center in St. Louis, Missouri: those with noncardiac surgery, illness, or neither. This enabled long-term tracking of cognitive function before and after surgery and illness. The effect of surgery and illness on longitudinal cognitive course was analyzed using a general linear mixed effects model. For participants without initial dementia, time to dementia onset was analyzed using sequential Cox proportional hazards regression. Results Of the 575 participants, 214 were nondemented and 361 had very mild or mild dementia at enrollment. Cognitive trajectories did not differ among the three groups (surgery, illness, control), although demented participants declined more markedly than nondemented participants. Of the initially nondemented participants, 23% progressed to a clinical dementia rating greater than zero, but this was not more common after surgery or illness. Conclusions The study did not detect long-term cognitive decline independently attributable to surgery or illness, nor were these events associated with accelerated progression to dementia. The decision to proceed with surgery in elderly people, including those with early Alzheimer disease, may be made without factoring in the specter of persistent cognitive deterioration.

This retrospective study recorded pertinent baseline geriatric assessment variables to identify risk factors for recurrence-free survival (RFS) and overall survival (OS) after hepatectomy in 100 consecutive patients aged ≥70 years with hepatocellular carcinoma. Patients had geriatric assessments of cognition, nutritional and functional statuses, and comorbidity burden, both preoperatively and at six months postoperatively. The rate of change in each score between preoperative and postoperative assessments was calculated by subtracting the preoperative score from the score at six months postoperatively, then dividing by the score at six months postoperatively. Patients with score change ≥0 comprised the maintenance group, while patients with score change <0 comprised the reduction group. The change in Geriatric 8 (G8) score at six months postoperatively was the most significant predictive factor for RFS and OS among the tested geriatric assessments. Five-year RFS rates were 43.4% vs. 6.7% (maintenance vs. reduction group; HR, 0.19; 95%CI, 0.11–0.31; p < 0.001). Five-year OS rates were 73.8% vs. 17.8% (HR, 0.12; 95%CI, 0.06–0.25; p < 0.001). Multivariate Cox proportional hazards analysis showed that perioperative maintenance of G8 score was an independent prognostic indicator for both RFS and OS. Perioperative changes in G8 scores can help forecast postoperative long-term outcomes in these patients.

Objective To examine the association of laryngoplasty, voice therapy, and pneumonia rate in patients with unilateral vocal fold paralysis (UVFP). Study Design Population-based retrospective cohort study. Setting Data were collected from the LHID2000 (Longitudinal Health Insurance Database 2000), containing the information of 1 million randomly selected patients in Taiwan. Methods In the LHID2000, we identified 439 patients having new diagnoses of UVFP from 1997 to 2013. We grouped the aforementioned patients according to UVFP treatment and probed the occurrence of pneumonia: 305 patients underwent laryngoplasty or voice therapy, and 134 patients did not undergo treatment. Follow-up procedures were executed for the enrollees until death or December 31, 2013, representing the end of the study period. We assessed the association of UVFP treatment and pneumonia by executing Cox proportional hazards regression. Results The pneumonia cumulative incidence was significantly higher among enrolled patients without treatment than in those receiving treatment ( P < .001). The pneumonia incidence was significantly lower in patients receiving UVFP treatment (hazard ratio, 0.49; 95% CI, 0.27-0.88; P = .018), as validated by the Cox proportional hazards model after adjustment. Patients undergoing laryngoplasty with or without voice therapy had a significantly lower incidence of pneumonia at 6 months and 1, 3, and 5 years, whereas those undergoing voice therapy alone did not. Conclusion Laryngoplasty was associated with a lower incidence of short- and long-term pneumonia in patients with UVFP. Physicians should encourage patients with UVFP at risk of aspiration to receive prompt evaluation as well as treatment.

Inter Pregnancy Interval

Abstract Recent evidence suggests that a long inter-pregnancy interval (IPI: time interval between live birth and estimated time of conception of subsequent pregnancy) poses a risk for adverse short-term perinatal outcome. We aimed to study the effect of short (<6 months) and long (>60 months) IPI on long-term cardiovascular morbidity of the offspring. A population-based cohort study was performed in which all singleton live births in parturients with at least one previous birth were included. Hospitalizations of the offspring up to the age of 18 years involving cardiovascular diseases and according to IPI length were evaluated. Intermediate interval, between 6 and 60 months, was considered the reference. Kaplan–Meier survival curves were used to compare the cumulative morbidity incidence between the groups. Cox proportional hazards model was used to control for confounders. During the study period, 161,793 deliveries met the inclusion criteria. Of them, 14.1% (n = 22,851) occurred in parturient following a short IPI, 78.6% (n = 127,146) following an intermediate IPI, and 7.3% (n = 11,796) following a long IPI. Total hospitalizations of the offspring, involving cardiovascular morbidity, were comparable between the groups. The Kaplan–Meier survival curves demonstrated similar cumulative incidences of cardiovascular morbidity in all groups. In a Cox proportional hazards model, short and long IPI did not appear as independent risk factors for later pediatric cardiovascular morbidity of the offspring (adjusted HR 0.97, 95% CI 0.80–1.18; adjusted HR 1.01, 95% CI 0.83–1.37, for short and long IPI, respectively). In our population, extreme IPIs do not appear to impact long-term cardiovascular hospitalizations of offspring.

Background: The cardiovascular (CV) events and mortality are significantly higher in hemodialysis (HD) patents compared to the general population. Although it is of clinical concern to predict the occurrence of CV events in long-term HD patients, more powerful predictor has under exploration. We investigated as to whether silent brain infarction (SBI) would be a predictable factor for future CV events and mortality in a large cohort of patients with long-term HD patients. Methods: After cranial magnetic resonance imaging to detect SBI, 202 long-term HD patients (7.1 ± 5.9 years) without symptomatic stroke were prospectively followed up until the incident of CV events (stroke, cardiac events, and death). We analyzed the prognostic role of SBI in CV events with the Kaplan-Meier method and Cox proportional hazards analysis. Results: The prevalence of SBI was quite higher compared to the previous reports (71.8% in all the patients). In overall patients, 60 patients suffered from CV disease (31 for coronary artery disease, 7 for congestive heart failure, 14 for symptomatic stroke) and 29 patients died (16 for CV death) during a follow up period (mean= 23 ± 13 months). In subgroup analysis regarding the presence of SBI, CV event-free survival rate for 4 years was significantly lower in the patients with SBI compared to those without SBI (54.6% vs. 86.7%, p=0.0003). CV and overall mortality were also significantly higher in SBI patients compared with No-SBI patients (CV mortality; 20.5 % vs. 4.3 %, overall mortality; 29.0% vs. 9.1% p< 0.01, respectively). Cox proportional hazards models showed that the presence of SBI was a significant predictor of cerebrovascular and CV events and CV and overall mortality even after adjustment for other CV risk factors listed on the Table . Conclusion: SBI detected with MRI would be powerful predictor of CV events and mortality in long-term HD patients. Hazard ratio (HR) of SBI for future events and mortality

Ciltacabtagene autoleucel (cilta-cel) is a Chimeric antigen receptor T-cell therapy with the potential for long-term disease control in heavily pre-treated patients with relapsed/refractory multiple myeloma (RRMM). As cilta-cel was assessed in the single-arm CARTITUDE-1 clinical trial, we used an external cohort of patients from the Therapie Monitor registry fulfilling the CARTITUDE-1 inclusion criteria to evaluate the effectiveness of cilta-cel for overall survival (OS) and time to next treatment (TTNT) vs. real-world clinical practice. Individual patient data allowed us to adjust the comparisons between both cohorts, using the inverse probability of treatment weighting (IPW; average treatment effect in the treated population (ATT) and overlap population (ATO) weights) and multivariable Cox proportional hazards regression. Outcomes were compared in intention-to-treat (HR, IPW-ATT: TTNT: 0.13 (95% CI: 0.07, 0.24); OS: 0.14 (95% CI: 0.07, 0.25); IPW-ATO: TTNT: 0.24 (95% CI: 0.12, 0.49); OS: 0.26 (95% CI: 0.13, 0.54)) and modified intention-to-treat (HR, IPW-ATT: TTNT: 0.24 (95% CI: 0.09, 0.67); OS: 0.26 (95% CI: 0.08, 0.84); IPW-ATO: TTNT: 0.26 (95% CI: 0.11, 0.59); OS: 0.31 (95% CI: 0.12, 0.79)) populations. All the comparisons were statistically significant in favor of cilta-cel. These results highlight cilta-cel’s potential as a novel, effective treatment to address unmet needs in patients with RRMM.
