Lower Risk Of All-cause Mortality Research Articles

All-cause mortality risk in long-acting injectable versus oral antipsychotics in schizophrenia: a systematic review and meta-analysis.

Patients with schizophrenia receiving antipsychotic treatment present lower mortality rates than those who do not. However, the non-adherence rate is high, which can be partially addressed using long-acting injectable (LAI) antipsychotics. The impact of LAI treatments on all-cause mortality compared to oral antipsychotics remains unclear. To fill that gap, a random effects meta-analysis was conducted to analyze the odds ratio (OR) of all-cause, suicidal, and non-suicidal mortality among patients taking LAI antipsychotics compared to oral antipsychotics (PROSPERO:CRD42023391352). Individual and pooled LAI antipsychotics were analyzed against pooled oral antipsychotics. Sensitivity analyses were performed for study design, setting, and industry sponsorship. Meta-regressions were conducted for gender, age, antipsychotic dose, and race. Seventeen articles, total sample 12,042 patients (N = 5795 oral, N = 6247 LAI) were included. Lower risk of all-cause mortality for patients receiving LAI antipsychotics vs receiving oral antipsychotics was found (OR = 0.79; 95%CI = 0.66-0.95). Statistical significance was maintained when only studies comparing the same LAI and oral antipsychotic were included (OR = 0.79; 95%CI = 0.66-0.95; p = <0.01), as well as for non-suicidal mortality (OR = 0.77: 95%CI = 0.63-0.94; p = 0.01), but not for suicidal mortality (OR = 0.86; 95%CI = 0.59-1.26; p = 0.44). Mortality reduction was more pronounced for LAI antipsychotics in first-episode psychosis (FEP) (OR = 0.79; 95%CI = 0.66-0.96) compared to chronic psychosis. No individual LAI reported statistically significant differences against all pooled oral antipsychotics. LAI antipsychotics are associated with a lower risk of all-cause and non-suicidal mortality in individuals with schizophrenia compared to oral antipsychotics. Better adherence to the medication and health services may explain this difference. Whenever possible, the use of LAIs should be considered from the FEP.

Impact of the medical fitness model on long term health outcomes in older adults

BackgroundPhysical inactivity is common among older adults and is associated with poor health outcomes. Medical fitness facilities provide a medically focused approach to physical fitness and can improve physical activity in their communities. This study aimed to assess the relationship between membership in the medical fitness model and all-cause mortality, health care utilization, and major adverse cardiac events in older adults.MethodsA propensity weighted retrospective cohort study linked individuals that attended medical fitness facilities to provincial health administrative databases. Older adults who had at least 1 year of health coverage from their index date between January 1st, 2005 to December 31st 2015 were included. Controls were assigned a pseudo-index date at random based on the frequency distribution of index dates in members. Members were stratified into low frequency attenders (< 1 Weekly Visits) and regular frequency attenders (> 1 Weekly Visits). Time to event models estimated the hazard ratios (HRs) for risk of all-cause mortality and major adverse cardiac event. Negative binomial models estimated the risk ratios (RRs) for risk of hospitalizations, outpatient primary care visits and emergency department visits.ResultsAmong 3,029 older adult members and 91,734 controls, members had a 45% lower risk of all-cause mortality (HR: 0.55, 95% CI: 0.50 – 0.61), 20% lower risk of hospitalizations (RR: 0.80, 95% CI: 0.75 – 0.84), and a 27% (HR: 0.72, 95% CI: 0.66 – 0.77), lower risk of a major adverse cardiovascular event. A dose–response effect with larger risk reductions was associated with more frequent attendance as regular frequency attenders were 4% more likely to visit a general practitioner for a routine healthcare visit (RR: 1.04, 95% CI: 1.01 – 1.07), but 23% less likely to visit the emergency department (RR: 0.87, 95% CI: 0.82 – 0.92).ConclusionsMembership at a medical fitness facility was associated with a decreased risk of mortality, health care utilization and cardiovascular events. The medical fitness model may be an alternative approach for public health strategies to promote positive health behaviors in older adult populations.

Association of oxidative balance score, cardiovascular, and all-cause mortality among patients with type 2 diabetes mellitus.

To investigate the association between oxidative balance score (OBS), cardiovascular mortality (CVM), and all-cause mortality (ACM) in type 2 diabetes mellitus (T2DM) patients. We included 6,119 participants with T2DM from the 2005-2020 National Health and Nutrition Examination Surveys (NHANES). The status of CVM and ACM of participants was followed through December 31, 2019. Multivariable Cox regression models, Kaplan-Meier curves, log-rank test, restricted cubic spline regression, and subgroup analysis, were used to evaluate the relationship between OBS, CVM, and ACM. During a median of 100.9 months follow-up, 1,790 ACM cases had occurred, 508 of which were due to cardiovascular disease. The T2DM participants were divided into four groups based on the quartiles of OBS. Participants with Q4 tended to be younger, financially better-off, married, highly educated, had lower alcohol consumption rates, were non-smokers, and exhibited a lower likelihood of ACM and CVM. In multivariate Cox regression models, compared with the patients with Q4, those with Q1 had a 30% increased risk for ACM (Q1, reference; Q4, HR: 0.70, 95%CI: 0.58-0.86) and a 43% increased risk for CVM (Q1, reference; Q4, HR: 0.57, 95%CI: 0.36-0.88). The restricted cubic spline regression models have no nonlinear relationship between OBS, CVM, and ACM. Kaplan-Meier survival curves showed that patients with Q4 had a lower risk of ACM and CVM (log-rank P < 0.05). We find that ACM and CVM increase with higher OBS in T2DM patients. Moreover, there are linear relationships between OBS, ACM, and CVM.

Association of weight loss strategies with all-cause and specific-cause mortality: a prospective cohort study

BackgroundThe health effects of different weight loss strategies vary greatly, and the relationship between weight loss strategies, especially the combination of multiple strategies, and death is still unclear. We aimed to examine the associations of various numbers and combinations of weight loss strategies with all-cause and specific-cause mortality and to further evaluate the associations of different total weight loss volumes with mortality.MethodsUsing data from NHANES (1999–2018) with 48,430 participants aged 20 and above, we collected fourteen self-reported weight loss strategies and identified five clusters using latent class analysis. Cox proportional hazards models were used to examine the association between the amounts and clusters of weight loss strategies and mortality.ResultsDuring a median follow-up of 9.1 years of 48,430 participants, 7,539 deaths were recorded (including 1,941 CVDs and 1,714 cancer). Participants who adopted 2, 3–4, and ≥ 5 weight loss strategies had a lower risk of all-cause mortality, with HRs of 0.88 (95% CI, 0.81 to 0.97), 0.89 (95% CI, 0.81 to 0.96) and 0.71 (95% CI, 0.61 to 0.82). Regardless of weight loss or weight gain categories, there was a significant trend toward reduced mortality as the number of weight loss strategies increased (P trend < 0.05). Participants who adopted cluster-1 (four strategies), cluster-2 (five strategies) and cluster-3 (three strategies) had a significantly lower risk of all-cause mortality, with HRs of 0.71 (95% CI, 0.60 to 0.84), 0.70 (95% CI, 0.55 to 0.89) and 0.81 (95% CI, 0.70 to 0.94). Among them, cluster-1 and cluster-2 are both characterized by eating less food, exercising, drinking plenty of water, lowering calories and eating less fat. Conversely, cluster-4 (five strategies) and cluster-5 (four strategies) had marginally significant effects, and they both had actual higher total energy intakes. Similar associations were observed for CVDs and cancer mortality.ConclusionsEmploying two or more weight loss strategies was associated with a lower risk of death, even among those who gained weight. Eating less food, exercising, drinking plenty of water, lowering calories and eating less fat is a better combination of strategies. On this basis, limiting the actual intake of total energy is necessary.

Sex differences in all-cause mortality and life span between women with premature menopause and men: propensity score matching analysis.

This study investigated sex differences in all-cause mortality and life span between women undergoing premature menopause and men using propensity score matching analysis. Data were from the National Health and Nutrition Examination Survey (1999-2018) and the National Health and Nutrition Examination Survey III (1988-1994). We included 3,214 women experiencing premature menopause and 23,067 men. The participants were all older than 40 years. Propensity score matching analysis created matched cohorts of women and men using a 1:1 ratio. We employed Cox proportional hazard models to estimate unadjusted and adjusted hazard ratios (HR) (95% confidence interval [CI]) for the association between sex and both all-cause mortality and survival up to the 75th percentile of life span. A subgroup analysis examined the effects of hormone therapy on mortality and life span. Compared with men in the matched cohorts, the adjusted HR values (95% CI) for all-cause mortality in women with age at menopause at <35, 35 to 39, and <40 years were 0.65 (0.54-0.78), 0.72 (0.59-0.87), and 0.67 (0.60-0.76), respectively. However, the adjusted HR values (95% CI) for women and men to survive to the 75th percentile of life span were not statistically significant. Besides, there was no significant difference in the mean life span between deceased women and men in the matched cohorts. In the subgroup analysis, the mean life span did not differ significantly between deceased women taking hormone therapy and men. However, the average life span of women never using hormone therapy was significantly longer than that of men (78.3 ± 11.6 vs 76.6 ± 11.9 years, P = 0.0154). Women experiencing premature menopause had lower risks of all-cause mortality than men, but the advantage that women had in terms of life span was insignificant.

Physical activity modification following a Transient Ischemic Attack in individuals with diabetes

BackgroundIndividuals with diabetes exhibit a higher risk of cardiovascular disease and mortality compared to healthy individuals. Following a transient ischemic attack (TIA) the risk of stroke and death increase further. Physical activity engagement after a TIA is an effective way of secondary prevention. However, there's a lack of research on how individuals with diabetes modify physical activity levels and how these adjustments impact survival post-TIA. This study aimed to determine the extent to which individuals with diabetes alter their physical activity levels following a TIA and to assess the impact of these changes on mortality.MethodsThis was a nationwide longitudinal study, employing data from national registers in Sweden spanning from 01/01/2003 to 31/12/2019. Data were collected 2 years retro- and prospectively of TIA occurrence, in individuals with diabetes. Individuals were grouped based on decreasing, remaining, or increasing physical activity levels after the TIA. Cox proportional hazards models were fitted to evaluate the adjusted relationship between change in physical activity and all-cause, cardiovascular, and non-cardiovascular mortality.ResultsThe final study sample consisted of 4.219 individuals (mean age 72.9 years, 59.4% males). Among them, 35.8% decreased, 37.5% kept steady, and 26.8% increased their physical activity after the TIA. A subsequent stroke occurred in 6.7%, 6.4%, and 6.1% of individuals, while death occurred in 6.3%, 7.3%, and 3.7% of individuals, respectively. In adjusted analyses, participants who increased their physical activity had a 45% lower risk for all-cause mortality and a 68% lower risk for cardiovascular mortality, compared to those who decreased their physical activity.ConclusionsPositive change in physical activity following a ΤΙΑ was associated with a reduced risk of mortality. Increased engagement in physical activity should be promoted after TIA, thereby actively supporting individuals with diabetes in achieving improved health outcomes.

Comparing the effectiveness of molnupiravir and nirmatrelvir-ritonavir in non-hospitalized and hospitalized COVID-19 patients with type 2 diabetes: A target trial emulation study.

To compare the effectiveness of molnupiravir and nirmatrelvir-ritonavir for non-hospitalized and hospitalized COVID-19 patients with type 2 diabetes (T2DM). Territory-wide electronic health records in Hong Kong were used to perform target trial emulation using a sequential trial approach. Patients (1) aged ≥18 years, (2) with T2DM, (3) with COVID-19 infection, and (4) who received molnupiravir or nirmatrelvir-ritonavir within 5 days of infection between 16 March 2022 and 31 December 2022 in non-hospital and hospital settings were included. Molnupiravir and nirmatrelvir-ritonavir initiators were matched using one-to-one propensity-score matching and followed for 28 days. Risk of outcomes was compared between groups by Cox regression adjusted for baseline characteristics. Subgroup analyses were performed on age (<70 years, ≥70 years), sex, Charlson comorbidity index (<4, ≥4), and number of COVID-19 vaccine doses (<2 doses, ≥2 doses). Totals of 17 974 non-hospitalized (8987 in each group) and 3678 hospitalized (1839 in each group) patients were identified. Non-hospitalized nirmatrelvir-ritonavir initiators had lower risk of all-cause mortality (absolute risk reduction [ARR] at 28 days 0.80%, 95% confidence interval [CI] 0.56-1.04; hazard ratio [HR] 0.47, 95% CI 0.30-0.73) and hospitalization (ARR at 28 days 4.01%, 95% CI 3.19-4.83; HR 0.73, 95% CI 0.66-0.82) as compared with molnupiravir initiators. Hospitalized nirmatrelvir-ritonavir initiators had reduced risk of all-cause mortality (ARR at 28 days 2.94%, 95% CI 1.65-4.23; HR 0.56, 95% CI 0.40-0.80) as compared with molnupiravir initiators. Consistent findings were found across all subgroups. The use of nirmatrelvir-ritonavir may be preferred to molnupiravir for COVID-19 patients with T2DM and without contraindication to either treatment.

Associations of multiple carotenoid co-exposure with all-cause and cause-specific mortality in US adults: a prospective cohort study.

Epidemiological evidence regarding circulating carotenoids and mortality risk remains conflicting, and most studies focus on the impact of individual carotenoids. This study aimed to elucidate the effects of co-exposure to multiple serum carotenoids on mortality risk. We enrolled 22,472 participants aged ≥20 from the National Health and Nutrition Examination Survey (NHANES) III (1988-1994) and NHANES 2003-2006. Baseline serum levels of five major carotenoids (α-carotene, β-carotene, lycopene, β-cryptoxanthin, and lutein/zeaxanthin) were measured, and individuals were followed up until December 31, 2019. Carotenoid co-exposure patterns were identified using the K-means method. Cox proportional hazard models were used to investigate the associations between carotenoid exposure and mortality risk. During a median follow-up of 16.7 years, 7,901 deaths occurred. K-means clustered participants into low-level, low-lycopene, high-lycopene, and high-level exposure groups. In the fully adjusted model, low-lycopene, high-lycopene, and high-level exposure groups had significantly lower all-cause mortality risks compared to the low-level exposure group, with hazard ratios (HRs) and 95% confidence intervals (CIs) of 0.79 (0.72, 0.87), 0.75 (0.67, 0.84), and 0.67 (0.61, 0.74), respectively. For cardiovascular disease mortality, the high-lycopene exposure group had a 27% reduced risk (HR: 0.73, 95% CI: 0.61-0.86), and the high-level exposure group had a 21% reduced risk (HR: 0.79, 95% CI: 0.67-0.93). For cancer mortality, the high-lycopene and high-level exposure groups had 30% and 35% lower risks, with HRs (95% CIs) of 0.70 (0.57, 0.86) and 0.65 (0.54, 0.79), respectively. This study revealed that co-exposure to multiple serum carotenoids was associated with reduced mortality risk, highlighting the potential health benefits of increased carotenoid intake. Further investigation is warranted to elucidate the underlying mechanisms of interactions among different carotenoids.

Serum 25-hydroxyvitamin D levels and risk of all-cause and cause-specific mortality: A 14-year prospective cohort study

Background & AimsThe circulating vitamin D level that is optimal for health is unknown. This study aimed to examine the association between circulating vitamin D level and risk of all-cause and cause-specific mortality. MethodsThis prospective cohort study included 18,797 Korean adults aged 40 years or older, living in rural areas, with no history of cancer or cardiovascular disease (CVD) at baseline. Serum 25-hydroxyvitamin D (25(OH)D) levels were measured at baseline. Participants were followed-up from the survey date (2005–2012) until December 31, 2021. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality by baseline vitamin D level. Restricted cubic splines were used to explore the nonlinearity. ResultsThe median (interquartile range) of 25(OH)D level was 55.8 (40.8–71.8) nmol/L. During a median follow-up of 14.3 years, 2,250 deaths were recorded. Compared with participants with a 25(OH)D level < 30 nmol/L, higher vitamin D levels (30 to < 50, 50 to < 75, and ≥ 75 nmol/L) were associated with a lower risk of all-cause mortality: HR (95% CI) of 0.82 (0.69–0.98), 0.74 (0.62–0.88), and 0.69 (0.57–0.84), respectively. A nonlinear relationship between vitamin D level and all-cause mortality was observed, with the risk plateauing between 50 and 60 nmol/L (p for nonlinearity = 0.009). The association was more pronounced for cancer-related mortality. HR 0.55 (95% CI: 0.39–0.77) for a 25(OH)D level ≥ 75 nmol/L compared with < 30.0 nmol/L. Low vitamin D levels were associated with increased CVD mortality in men. ConclusionsVitamin D level was inversely associated with all-cause and cause-specific mortality in middle-aged and older adults. Maintaining a serum 25(OH)D level of approximately 50–60 nmol/L may contribute to longevity and warrants further investigation.

Sex Differences in Long-term Heart Failure Prognosis: A Comprehensive Meta-Analysis.

Sex differences in the long-term prognosis of heart failure (HF) remain controversial, and there is a lack of comprehensive pooling of the sex differences in outcomes of HF. This study aims to characterize the sex differences in the long-term prognosis of HF and explore whether these differences vary by age, HF course, left ventricular ejection fraction, region, period of study, study design, and follow-up duration. A systematic review was conducted using Medline, Embase, Web of Science, and the Cochrane Library, from January 1, 1990, to March 31, 2024. The primary outcome was all-cause mortality (ACM), and the secondary outcomes included cardiovascular mortality (CVM), hospitalization for HF (HHF), all-cause hospitalization, a composite of ACM and HHF, and a composite of CVM and HHF. Pooled hazard risks (HRs) with corresponding 95% confidence intervals (CIs) were calculated using random effects meta-analysis. 94 studies (comprising 96 cohorts) were included in the meta-analysis, representing 706,247 participants (56.5% were men, the mean age was 71.0 years). Female HF patients had a lower risk of ACM (HR: 0.83, 95% CI: 0.80, 0.85; I2=84.9%), CVM (HR: 0.84, 95% CI: 0.79, 0.89; I2=70.7%), HHF (HR: 0.94, 95% CI: 0.89, 0.98; I2=84.0%), and composite endpoints (ACM+HHF: HR: 0.89, 95% CI: 0.83, 0.95; I2=80.0%; CVM+HHF: HR: 0.85, 95% CI: 0.77, 0.93; I2=87.9%) compared to males. Subgroup analysis revealed that the lower risk of mortality observed in women was more pronounced among individuals with long-course HF (i.e., chronic HF, follow-up duration >2 years) or recruited in the randomized controlled trials. (P for interaction <0.05). Female HF patients had a better prognosis compared to males, with lower risks of ACM, CVM, HHF, and composite endpoints. Despite the underrepresentation of female populations in HF clinical trials, their mortality benefits tended to be lower than in real-world settings. PROSPERO: CRD42024526100.

Trajectory Patterns of Macronutrient Intake and Their Associations with Obesity, Diabetes, and All-Cause Mortality: A Longitudinal Analysis over 25 Years.

Over the past decades, China has been undergoing rapid economic growth, which may have significantly influenced the dietary patterns and health status of the Chinese population. Our study aimed to assess the associations of potential macronutrient trajectory patterns with chronic diseases and all-cause mortality using the latent class trajectory model (LCTM) and the longitudinal data of the China Health and Nutrition Survey obtained between 1991 and 2015. A 24-hour diet recall was used to assess the dietary intake. The Poisson regression model was employed to investigate the correlations between trajectory patterns and chronic diseases and all-cause mortality. A total of 8115 participants were included in the final analysis. We explored four and three trajectory patterns for male and female populations, respectively. We found that a decreasing very high-carbohydrate trajectory together with a U-shape protein trajectory was associated with a higher risk of diabetes in the male population (odds ratio (OR): 2.23; 95% confidence interval (CI): 1.31-3.77). A similar pattern for moderate protein intake was also associated with the risk of diabetes in the female population (OR: 1.82; 95% CI: 1.18-2.79). In addition, we show that a decreasing low-carbohydrate trajectory and an increasing high-fat trajectory were associated with a lower risk of all-cause mortality (OR: 0.76; 95% CI: 0.60-0.96) and a higher risk of obesity (OR: 1.24; 95% CI: 1.05-1.47) in males. Our results shed light on some salient nutritional problems in China, particularly the dual challenges of undernutrition and overnutrition.

Dietary magnesium intake and rheumatoid arthritis patients’ all-cause mortality: evidence from the NHANES database

BackgroundRheumatoid arthritis (RA) is a chronic inflammatory joint disease with all-cause mortality increasing globally. Dietary magnesium (Mg), an anti-inflammatory nutrient, has been proven to be associated with the all-cause mortality. The association of dietary Mg intake and all-cause mortality in RA patients remains unknown. The aim of this study was to assess the association between dietary Mg intake and all-cause mortality in RA patients.MethodsRA patients were extracted from the NHANES 1999–2018, and followed for survival through December 31, 2019. Dietary Mg intake data were obtained from 24-h dietary recall interview. The association between dietary Mg intake and RA patients’ all-cause mortality was explored based on weighted univariate and multivariate Cox proportional hazard models and described as absolute risk difference (ARD), hazard ratios (HRs) and 95% confidence intervals (CIs). This association was further explored in subgroup analyses based on different age, gender and body mass index (BMI).ResultsTotally 2,952 patients were included. Until 31 December 2019, a total of 825 deaths were documented. RA patients with higher dietary Mg intake had a 11.12% reduction of all-cause mortality (ARD=-11.12%; HR = 0.74, 95%CI: 0.56–0.99) in the fully adjusted model, especially in female (HR = 0.68, 95%CI: 0.47–0.98), aged < 65 years (HR = 0.59, 95%CI: 0.37–0.94) and BMI ≤ 30 kg/m2 (HR = 0.62, 95%CI: 0.42–0.91).ConclusionRA patients who consumed adequate dietary Mg from diet as well as supplements may had a lower risk of all-cause mortality.

Long-term liver-related outcomes and liver stiffness progression of statin usage in steatotic liver disease

BackgroundStatins have multiple benefits in patients with metabolic-associated steatotic liver disease (MASLD).AimTo explore the effects of statins on the long-term risk of all-cause mortality, liver-related clinical events (LREs) and liver...

Impact of depression on in-hospital outcomes for adults with type 2 myocardial infarction: A United States population-based analysis.

Type 2 myocardial infarction (T2MI) is an ischemic myocardial injury in the context of oxygen supply/demand mismatch in the absence of a primary coronary event. However, though there is a rising prevalence of depression and its potential association with type 1 myocardial infarction (T1MI), data remains non-existent to evaluate the association with T2MI. To identify the prevalence and risk of T2MI in adults with depression and its impact on the in-hospital outcomes. We queried the National Inpatient Sample (2019) to identify T2MI hospitalizations using Internal Classification of Diseases-10 codes in hospitalized adults (≥ 18 years). In addition, we compared sociodemographic and comorbidities in the T2MI cohort with vs without comorbid depression. Finally, we used multivariate regression analysis to study the odds of T2MI hospitalizations with vs without depression and in-hospital outcomes (all-cause mortality, cardiogenic shock, cardiac arrest, and stroke), adjusting for confounders. Statistical significance was achieved with a P value of < 0.05. There were 331145 adult T2MI hospitalizations after excluding T1MI (median age: 73 years, 52.8% male, 69.9% white); 41405 (12.5%) had depression, the remainder; 289740 did not have depression. Multivariate analysis revealed lower odds of T2MI in patients with depression vs without [adjusted odds ratio (aOR) = 0.88, 95% confidence interval (CI): 0.86-0.90, P = 0.001]. There was the equal prevalence of prior MI with any revascularization and a similar prevalence of peripheral vascular disease in the cohorts with depression vs without depression. There is a greater prevalence of stroke in patients with depression (10.1%) vs those without (8.6%). There was a slightly higher prevalence of hyperlipidemia in patients with depression vs without depression (56.5% vs 48.9%), as well as obesity (21.3% vs 17.9%). There was generally equal prevalence of hypertension and type 2 diabetes mellitus in both cohorts. There was no significant difference in elective and non-elective admissions frequency between cohorts. Patients with depression vs without depression also showed a lower risk of all-cause mortality (aOR = 0.75, 95%CI: 0.67-0.83, P = 0.001), cardiogenic shock (aOR = 0.65, 95%CI: 0.56-0.76, P = 0.001), cardiac arrest (aOR = 0.77, 95%CI: 0.67-0.89, P = 0.001) as well as stroke (aOR = 0.79, 95%CI: 0.70-0.89, P = 0.001). This study revealed a significantly lower risk of T2MI in patients with depression compared to patients without depression by decreasing adverse in-hospital outcomes such as all-cause mortality, cardiogenic shock, cardiac arrest, and stroke in patients with depression.

Dietary Intake of Polyphenols and All-Cause Mortality: A Systematic Review with Meta-Analysis.

Polyphenols are secondary metabolites found in plants, foods, and drinks, occurring in small quantities and showcasing antioxidant and anti-inflammatory qualities. The primary polyphenols consist of flavonoids, phenolic acids, stilbenes, and lignans. However, there is currently no comprehensive quantitative analysis of epidemiological data on overall death rates. This systematic review with meta-analysis aims to identify the exposure-response relationship between dietary polyphenol intake and all-cause mortality. The literature was reviewed from its earliest study to May 2024, utilizing six distinct electronic databases. No specific criteria were used to choose participants based on the recruiting environment, their general health condition, country, or ethnicity. The inclusion criteria for studies were as follows: a longitudinal design, exposure to dietary polyphenols, all-cause mortality as the outcome, and hazard risk (HR) as the impact measure. The Newcastle-Ottawa Scale was used to evaluate the methodological rigor of the study. The hazard risks (HRs) and 95% confidence intervals (CIs) were estimated by pooling data using common effects models. A protocol has been registered on PROSPERO with the identification number CRD42024545524. The meta-analysis comprised seven cohort studies that involved 178,657 adult people aged 18 years and older. These studies examined the relationship between total dietary polyphenol consumption and the risk of all-cause death. The recruitment settings exclusively used community-based approaches, with a preference for Europe (71%) in terms of geographic distribution. The study's quality was assessed to be moderate to high. The meta-analysis showed consistent evidence that increased dietary exposure to polyphenols reduces the risk of all-cause mortality by 7% (HR 0.93, 95% CI 0.91-0.95, I2: 48%). Pooled data from the available evidence consistently show that individuals exposed to an antioxidant diet rich in polyphenol sources may be at lower risk of all-cause mortality.

Association of psychological resilience with all-cause and cause-specific mortality in older adults: a cohort study

BackgroundPsychological resilience has been associated with increased longevity in the oldest old; however, its significance in the broader older adult population has not been thoroughly explored. There is a lack of understanding regarding its relationship with cause-specific mortality in older adults. This study aims to address these gaps by investigating the association between psychological resilience and both overall mortality and cause-specific mortality in individuals aged 65 and older.MethodsWe enrolled 4,935 participants aged 65 and older in the Chinese Longitudinal Healthy Longevity Survey, with baseline assessments conducted in 2014 and follow-up surveys in 2018. To evaluate the associations between psychological resilience and mortality, we used Cox proportional hazards models. Additionally, we employed restricted cubic spline plots to illustrate the dose-response relationships between these variables.ResultsDuring a mean (Standard Deviation) follow-up of 3.2 years (1.2), 1726 participants died. Higher psychological resilience was independently associated with lower all-cause mortality risk (Hazard ratio [HR] 0.74, 95% confidence interval [CI]: 0.67–0.82) and cause-specific mortality from cardiovascular disease (HR 0.74, 95% CI: 0.59–0.93), respiratory diseases (HR 0.63, 95% CI:0.45–0.87), and other causes (HR 0.69, 95% CI: 0.60–0.78), excluding cancer-related mortality. Similar effects were evident when examining the psychological resilience score. The dose-response analysis further indicated a gradual decrease in mortality risk corresponding to higher psychological resilience scores. Interaction analyses revealed that psychological resilience has a more pronounced effect on mortality from other causes among economically independent older adults (P-interaction = 0.02).ConclusionsEnhanced psychological resilience is independently associated with reduced all-cause and some cause-specific mortality in older adults. These findings underscore the importance of addressing psychological factors in the promotion of healthy aging and longevity.

Distribution and prognostic impact of different heart failure etiologies in patients with heart failure with mildly reduced ejection fraction

ObjectiveThe study investigates the characteristics and prognostic impact of different heart failure (HF) etiologies in patients with heart failure with mildly reduced ejection fraction (HFmrEF). BackgroundData regarding the characterization of patients with HFmrEF and their outcomes is scarce. MethodsConsecutive patients with HFmrEF (i.e., left ventricular ejection fraction 41–49 % and signs and/or symptoms of HF) were retrospectively included at one institution from 2016 to 2022. Patients with ischemic cardiomyopathy (ICM) were compared to patients without ischemic cardiomyopathy (non-ICM). The primary endpoint was all-cause mortality at 30 months (median follow-up). Statistical analyses included Kaplan-Meier, multivariable Cox proportional regression analyses and propensity score matching. ResultsFrom a total of 1,832 patients hospitalized with HFmrEF, ICM was the most common HF etiology in 68.7 %, followed by hypertensive (9.7 %) and primary non-ischemic cardiomyopathies (NICM) (8.1 %). Within the entire study cohort, the presence of ICM was not associated with the risk of all-cause mortality (HR = 0.864; 95 % CI 0.723 – 1.031), however after multivariable adjustment (HR = 0.792; 95 % CI 0.646 – 0.972; p = 0.026) and propensity score matching (25.7% vs. 31.4 %; log rank p = 0.050), the presence of ICM was associated with lower risk of all-cause mortality at 30 months compared to patients without ICM. ConclusionICM is the most common etiology of HF in HFmrEF and may be associated with favorable outcomes. This may be related to better adherence to pharmacological treatment and improved revascularization strategies for HFmrEF patients with ICM.

Home based cardiac rehabilitation: A retrospective cohort analysis on all-cause mortality and hospital readmission rates across sexes and races

ObjectiveStudies have shown that both home-based cardiac rehabilitation (HBCR) and center-based cardiac rehabilitation (CBCR) exhibit comparable efficacy in reducing mortality during short-term follow-up periods of up to 12 months. However, research on sex- and race-specific outcomes associated with HBCR is limited. This study examines all-cause mortality and hospital readmission among patients referred to HBCR, with stratification by sex and race. MethodsThis Kaiser Permanente Southern California (KPSC) retrospective cohort study followed 6,868 patients from HBCR referral until death, disenrollment, or December 31, 2021. There were 3,835 HBCR graduates, 722 non-graduates, and 2,311 non-enrolled patients. Cox models were used to estimate hazard ratios (HR) and 95 % confidence intervals (CI) comparing 1) HBCR graduates vs. non-enrolled, and 2) HBCR graduates vs. non-graduates, stratified by sex and race. Differential outcomes among strata were analyzed using Kaplan-Meier curves. ResultsAmong the 6,868 patients referred to HBCR, 4693 (68.3 %) were male, 2,175 (31.7 %) female, 870 (12.7 %) Asian/Pacific Islander, 731 (10.6 %) African American, 1,612 (23.6 %) Hispanic/Latino, and 3,646 non-Hispanic White (53.1 %). Over a mean follow-up period of 2.28 years, HBCR graduates, compared to patients who did not enroll in HBCR, had overall significantly lower risks of all-cause mortality and hospitalization. These results remained significant with stratification by sex and race. Compared to HBCR non-graduates, HBCR graduates overall had significantly lower risks of all-cause mortality and hospitalization. In the same comparison, mortality risk was significantly reduced for male and White patients; risk of hospital readmission was significantly reduced in both sexes, African American, and White patients. Among HBCR graduates, no significant differences in all-cause mortality or hospital readmission were observed across sexes and races. ConclusionHBCR participation is associated with reduction of all-cause mortality and hospital readmission rates across sexes and races. Notably, we observed benefits at varying levels of engagement, which suggests that even partial completion of HBCR is associated with risk reduction. Among HBCR graduates, we found similar outcomes across sexes and races, which suggests that the program can be effective among diverse patient groups.

Associations Between Dietary Intake of Tomato and Lycopene with All-Cause and Cancer-Specific Mortality in US Adults with Diabetes: Results From a Cohort Study

This study aimed to explore the association between dietary intake of tomatoes and lycopene with all-cause and cancer mortality among US adults with diabetes. We hypothesized that a higher intake of tomato and lycopene is related to a reduced risk of all-cause and cancer mortality among adults with diabetes. This prospective study was conducted among 9213 US adults with diabetes using data from the National Health and Nutrition Examination Survey (NHANES) 2007–2016. Data on dietary intake of tomatoes and lycopene were obtained from two 24-h dietary recalls. Multivariate Cox proportional hazard models determined the associations between tomato/lycopene intake and mortality. A higher intake of tomatoes and lycopene was significantly associated with a lower risk of all-cause mortality (tomato: Q5 vs. Q1: HR = 0.68, 95% CI = 0.54–0.86, p = 0.001, p for trend = 0.001; lycopene: Q5 vs. Q1: HR = 0.78, 95% CI = 0.64–0.95, p = 0.013, p for trend = 0.006) after adjusting for all covariates. Compared with the lowest quintile of tomato and lycopene intake, the highest quintile was associated with a lower risk of cancer mortality (tomato: HR = 0.58, 95% CI = 0.35–0.96, p = 0.035; lycopene: HR = 0.63, 95% CI = 0.40–0.98, p = 0.043). Our study demonstrated that dietary intake of tomatoes and lycopene was significantly associated with a lower risk of all-cause mortality in US adults with diabetes. High consumption of tomatoes and lycopene was also related to reduced cancer mortality in US adults with diabetes.

Outcomes and Hospital Service Use Among Patients With COPD in a Nurse- and Allied Health–Led Clinic

Multidisciplinary disease management efforts enable the improvement in lung function among patients with chronic obstructive pulmonary disease (COPD), but there is little evidence of its association with risks of adverse health outcomes and health care service use. To examine the association between the use of a nurse- and allied health-led primary care clinic for respiratory patients, namely the Nurse and Allied Health Clinic-Respiratory Care (NAHC-Respiratory), and their risks of mortality and morbidity and health care service use. This territory-wide, population-based, propensity-matched, retrospective cohort study used data from the electronic health records of all patients who used public health care services in Hong Kong, China, from January 1, 2010, to December 31, 2019. All patients with COPD treated in public outpatient clinics between January 1, 2010, and December 31, 2014, were included. Patients who attended NAHC-Respiratory and usual care only were propensity score-matched at a 1:2 ratio. Data analyses were conducted between August 2023 and April 2024. Attendance at NAHC-Respiratory. All-cause and cause-specific mortality, incidence of COPD complications, and use of emergency department and inpatient services until the end of 2019 were compared between the NAHC-Respiratory and usual care participants using Cox proportional hazard regression, Poisson regression, and log-link gamma regression models after matching. This study included 9048 eligible patients after matching, including 3093 in the exposure group (2814 [91.0%] men; mean [SD] age, 69.8 [9.5] years) and 5955 in the reference group (5431 [91.2%] men; mean [SD] age, 69.5 [11.7] years). Compared with patients in the usual care-only group (reference), patients in the exposure group had lower risks of all-cause mortality (hazard ratio [HR], 0.84; 95% CI, 0.78-0.90) as well as pneumonia-caused (HR, 0.85; 95% CI, 0.74-0.97), respiratory-caused (HR, 0.86; 95% CI, 0.77-0.96), and cardiovascular-caused (HR, 0.74; 95% CI, 0.59-0.93) mortality. Exposure was associated with reduced rates of emergency department visits (incidence rate ratio [IRR], 0.92; 95% CI, 0.86-0.98) and hospitalization through emergency department (IRR, 0.89; 95% CI, 0.83-0.95). In this cohort study, the use of a nurse- and allied health-led clinic in primary care settings was associated with reduced risks of mortality and use of hospital services among patients with COPD. These findings emphasize the important role of health care workers other than physicians in disease management in the primary care setting. The NAHC-Respiratory model and service components can be used to help improve primary care programs to benefit more patients with COPD.
