ABSTRACT

OBJECTIVES: The benefits of early rehabilitation for patients with acute heart failure (HF) requiring IV inotropic drugs have yet to be determined. We investigated the association between early rehabilitation and short-term clinical outcomes in patients with acute HF requiring IV inotropic drugs. DESIGN: Retrospective cohort study. SETTING: This study used data including more than 90% of patients at a tertiary emergency hospital in Japan. PATIENTS: This study included patients with acute HF who required IV inotropic drugs within 2 days of admission. INTERVENTIONS: We compared patients who commenced rehabilitation within 2 days of admission (the early rehabilitation group) and those who did not (the control group). MEASUREMENTS AND MAIN RESULTS: Propensity score matching was used to compare in-hospital mortality, 30-day all-cause and HF readmissions, length of stay, and Barthel Index (BI) at discharge between patients who received early rehabilitation and those who did not. Totally, 38,302 patients were eligible for inclusion; of these, 5,127 received early rehabilitation and 5,126 pairs were generated by propensity score matching. After propensity score matching, the patients who received early rehabilitation had a lower in-hospital mortality rate than those who did not (9.9% vs. 13.2%; p < 0.001). The relative risk (95% CI) of early rehabilitation for in-hospital mortality was 0.75 (0.67-0.83). Patients undergoing early rehabilitation exhibited a shorter mean length of stay (25.5 vs. 27.1; p < 0.001), lower 30-day all-cause (14.1% vs. 16.4%; p = 0.001) and HF (8.6% vs. 10.4%; p = 0.002) readmissions, and higher BI scores at discharge (68 vs. 67; p = 0.096). Consistent findings were observed across subgroups, including in patients 80 years old or older, those with a body mass index less than 18.5 kg/m2, and those with BI scores less than 60. CONCLUSIONS: The early prescription of rehabilitation was associated with favorable short-term outcomes even for patients with acute HF requiring IV inotropic drugs.

ABSTRACT

BACKGROUND: Identifying accurate prognostic factors is crucial for postoperative management of early gastric cancer (EGC) patients. Skeletal muscle quality (SMQ), defined by muscle density on computed tomography (CT) images, has been proposed as a novel prognostic factor. This study compared the prognostic significance of SMQ changes with the well-established factor of body weight (BW) loss in the postoperative EGC setting. METHODS: This single-center retrospective study included 297 postoperative EGC patients (median age 69 years, 68.4% male) who had preoperative and 1-year-postoperative gastrectomy CT images. SMQ was defined as the modified intramuscular adipose tissue content (mIMAC = skeletal muscle density-subcutaneous fat density on CT images) and the change as ΔmIMAC. Log-rank test, Kaplan-Meier survival, and Cox proportional hazards regression analyses were used to assess the associations between prognosis and either ΔmIMAC or BW change (ΔBW). Prognosis prediction by ΔmIMAC and ΔBW was compared by using the area under the curve (AUC) of the receiver operating characteristic curve. RESULTS: ΔmIMAC was significantly associated with prognosis (log-rank test; P = 0.037), but ΔBW was not (P = 0.243). Prognosis was significantly poorer in the severely decreased mIMAC group than in the preserved group (multivariate Cox proportional hazards regression analysis; P = 0.030) but was unaffected by BW changes (P = 0.697). The AUC indicated a higher prognostic value for ΔmIMAC than ΔBW (ΔmIMAC: AUC = 0.697, ΔBW: AUC = 0.542). CONCLUSIONS: One-year post-gastrectomy SMQ changes may be better prognostic EGC predictors than BW changes.

ABSTRACT

INTRODUCTION: Osteosarcopenia is an age-related syndrome characterized by the coexistence of osteoporosis and sarcopenia. Little is known about the clinical implications of osteosarcopenia among patients undergoing hemodialysis. This study investigated the prevalence of osteosarcopenia and its association with all-cause mortality and fractures in this population. MATERIALS AND METHODS: This retrospective cohort study included outpatients undergoing hemodialysis in Japan. Sarcopenia was defined according to the recommendations of the Asian Working Group for Sarcopenia 2019. Osteoporosis was defined as a T-score of the calcaneus bone < - 2.5. We divided patients into three groups: robust (no osteoporosis or sarcopenia), osteoporosis or sarcopenia alone (osteoporosis without sarcopenia or sarcopenia without osteoporosis), and osteosarcopenia (osteoporosis and sarcopenia). Cox proportional-hazard and negative binomial regression models were used to estimate the associations between osteosarcopenia and all-cause mortality and fractures. RESULTS: Among the 328 patients (mean age, 65.5 ± 11.3 years; men, 59.1%), the prevalence of osteosarcopenia was 22.9%. During the follow-up period (1972 person-years), 131 deaths and 113 fractures occurred. Patients with osteoporosis or sarcopenia alone (hazard ratio 1.36; 95% confidence interval 0.85-2.18) and osteosarcopenia (hazard ratio 2.13; 95% confidence interval, 1.23-3.68) showed a higher risk of all-cause mortality than the robust group. Similar results were observed for the risk of fractures in patients with osteosarcopenia. CONCLUSIONS: Patients undergoing hemodialysis showed a high prevalence of osteosarcopenia, and osteosarcopenia was associated with a poor prognosis in this patient population. Assessing osteosarcopenia may be useful for accurate prognostic stratification of patients undergoing hemodialysis.

ABSTRACT

BACKGROUND: This study aimed to clarify the effects of exercise-based cardiac rehabilitation (CR) on patients with heart failure. METHODS AND RESULTS: Patients were divided into groups according to intervention duration (<6 and ≥6 months). We searched for studies published up to July 2023 in Embase, MEDLINE, PubMed, and the Cochrane Library, without limitations on data, language, or publication status. We included randomized controlled trials comparing the efficacy of CR and usual care on mortality, prehospitalization, peak oxygen uptake (V̇O2), and quality of life. Seventy-two studies involving 8,495 patients were included in this review. It was found that CR reduced the risk of rehospitalization for any cause (risk ratio [RR] 0.80; 95% confidence interval [CI] 0.70-0.92) and for heart failure (RR 0.88; 95% CI 0.78-1.00). Furthermore, CR was found to improve exercise tolerance (measured by peak V̇O2and the 6-min walk test) and quality of life. A subanalysis performed based on intervention duration (<6 and ≥6 months) revealed a similar trend. CONCLUSIONS: Our meta-analysis showed that although CR does not reduce mortality, it is effective in reducing rehospitalization rates and improving exercise tolerance and quality of life, regardless of the intervention duration.

ABSTRACT

BACKGROUND: This study determined the incidence of hospitalization-associated disability (HAD) and its characteristics in older patients with heart failure in Japan. METHODS AND RESULTS: Ninety-six institutions participated in this nationwide multicenter registry study (J-Proof HF). From December 2020 to March 2022, consecutive heart failure patients aged ≥65 years who were prescribed physical rehabilitation during hospitalization were enrolled. Of the 9,403 patients enrolled (median age 83.0 years, 50.9% male), 3,488 (37.1%) had HAD. Compared with the non-HAD group, the HAD group was older and had higher rates of hypertension, chronic kidney disease, and cerebrovascular disease comorbidity. The HAD group also had a significantly lower Barthel Index score and a significantly higher Kihon checklist score before admission. Of the 9,403 patients, 2,158 (23.0%) had a preadmission Barthel Index score of <85 points. Binomial logistic analysis revealed that age and preadmission Kihon checklist score were associated with HAD in patients with a preadmission Barthel Index score of ≥85, compared with New York Heart Association functional classification and preadmission cognitive decline in those with a Barthel Index score <85. CONCLUSIONS: This nationwide registry survey found that 37.1% of older patients with HF had HAD and that these patients are indicated for convalescent rehabilitation. Further widespread implementation of rehabilitation for older patients with heart failure is expected in Japan.

ABSTRACT

To improve the efficiency of pathological diagnoses, the development of automatic pathological diagnostic systems using artificial intelligence (AI) is progressing; however, problems include the low interpretability of AI technology and the need for large amounts of data. We herein report the usefulness of a general-purpose method that combines a hyperspectral camera with machine learning. As a result of analyzing bile duct biopsy and bile cytology specimens, which are especially difficult to determine as benign or malignant, using multiple machine learning models, both were able to identify benign or malignant cells with an accuracy rate of more than 80% (93.3% for bile duct biopsy specimens and 83.2% for bile cytology specimens). This method has the potential to contribute to the diagnosis and treatment of bile duct cancer and is expected to be widely applied and utilized in general pathological diagnoses.

ABSTRACT

Perme intensive care unit (ICU) mobility score is a comprehensive mobility assessment tool; however, its usefulness and validity for patients after cardiovascular surgery remain unclear. We investigated the association between the Perme Score and clinical outcomes after cardiovascular surgery. We retrospectively enrolled 249 consecutive patients admitted to the ICU after cardiac and/or major vascular surgery. The Perme Score contains categories on mental status, potential mobility barriers, muscle strength and mobility level and was assessed within 2 days after surgery. The outcomes of physical recovery were the number of days until 100-m ambulation achievement and 6-min walk distance (6MWD) at hospital discharge. The endpoint was a composite outcome of all-cause mortality and/or all-cause unplanned readmission. We analyzed the associations of the Perme Score with physical recovery and the incidence of clinical events. After adjusting for clinical confounding factors, a higher Perme Score was an independent factor of earlier achievement of 100-m ambulation (hazard ratio: 1.039, 95% confidence interval [CI]: 1.012-1.066) and higher 6MWD (ß: 0.293, P = .001). During the median follow-up period of 1.1 years, we observed an incidence rate of 19.4/100 person-years. In the multivariate Poisson regression analysis, a higher Perme Score was significantly and independently associated with lower rates of all-cause death/readmission (incident rate ratio: 0.961, 95% CI: 0.930-0.992). The Perme Score within 2 days after cardiovascular surgery was associated with physical recovery during hospitalization and clinical events after discharge. Thus, it may be useful for predicting clinical outcomes.

ABSTRACT

Both cancer and cardiovascular disease (CVD) cause skeletal muscle mass loss, thereby increasing the likelihood of a poor prognosis. We investigated the association between cancer history and physical function and their combined association with prognosis in patients with CVD. We retrospectively reviewed 3,796 patients with CVD (median age: 70 years; interquartile range [IQR]: 61-77 years) who had undergone physical function tests (gait speed and 6-minute walk distance [6MWD]) at discharge. We performed multiple linear regression analyses to assess potential associations between cancer history and physical function. Moreover, Kaplan-Meier curves and Cox regression analyses were used to evaluate prognostic associations in four groups of patients categorized by the absence or presence of cancer history and of high or low physical function. Multiple regression analyses showed that cancer history was significantly and independently associated with a lower gait speed and 6MWD performance. A total of 610 deaths occurred during the follow-up period (median: 3.1 years; IQR: 1.4-5.4 years). The coexistence of low physical function and cancer history in patients with CVD was associated with a significantly higher mortality risk, even after adjusting for covariates (cancer history/low gait speed, hazard ratio [HR]: 1.93, P < 0.001; and cancer history/low 6MWD, HR: 1.61, P = 0.002). Cancer history is associated with low physical function in patients with CVD, and the combination of both factors is associated with a poor prognosis.

ABSTRACT

BACKGROUND: Patients undergoing hemodialysis (HD) have difficulty increasing their gait speed in daily life. The extent of the increase from the usual gait speed (UGS) to the maximum gait speed (MGS) is considered the reserved gait capacity (RGC). Little is known regarding the implications of RGC. This study aimed to investigate the association between RGC and all-cause mortality in patients undergoing HD. METHODS: In this retrospective study, we assessed the usual and maximum 10-m walking speed of outpatients who underwent HD between October 2002 and August 2021. RGC was defined as the ratio of MGS to UGS. Patients were divided into three groups according to the tertiles of RGC (low, moderate and high). A Cox proportional hazards regression model was used to examine the association between RGC and all-cause mortality. RESULTS: Of the 496 (median age 66.0 years; men 59%) participants, 186 patients died during the follow-up (incident ratio of 62.0 per 1000 person-years). The patients with moderate [hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.46-0.94] and high (HR 0.44, 95% CI 0.30-0.65) RGC had a lower risk of mortality than the low RGC group. Furthermore, even when restricted to a population with only UGS <1.0 m/s, the group with high RGC still had a lower risk of mortality than those with low RGC (HR 0.55, 95% CI 0.33-0.94). CONCLUSIONS: Lower RGC was independently associated with an increased risk of all-cause mortality among patients on HD; high RGC had a survival advantage even with a slow UGS.

ABSTRACT

BACKGROUND: Frailty is associated with adverse outcomes in patients undergoing hemodialysis (HD). However, no study has used various frailty assessments in patients on HD to examine their association with clinical events. In this study, we investigated the association between clinical events and six frailty scales. METHODS: Outpatients who underwent HD between 2018 and 2020 were retrospectively enrolled. Frailty was defined using the Fried Frailty Phenotype, Study of Osteoporotic Fractures (SOF) Index, Short Physical Performance Battery (SPPB), Frail Screening Index, FRAIL scale and Clinical Frailty Scale. Outcomes were clinical events, including a composite of multiple (i.e. recurrent) all-cause hospitalizations, fractures and/or all-cause mortality. The association of clinical events and the frailty scales were investigated using negative binomial regression analysis. RESULTS: Fried Frailty Phenotype [incident rate ratio (IRR), 1.62; 95% confidence interval (CI), 1.49-1.76], SOF Index (IRR, 1.42; 95% CI, 1.10-1.83), SPPB (IRR, 1.79; 95% CI, 1.11-2.88) and Clinical Frailty Scale (IRR, 1.65; 95% CI, 1.04-2.61) were significantly associated with clinical events. However, Frail Screening Index (IRR, 1.38; 95% CI, 0.60-3.18) and FRAIL scale (IRR, 1.30; 95% CI, 0.88-1.92) showed no significant association with clinical events. CONCLUSIONS: Objective frailty assessments (SPPB) and medical staff impression-based frailty (Clinical Frailty Scale) may be useful prognostic predictors for patients on HD. Questionnaire-based frailty assessment should be carefully considered when used as a measurement of frailty.

ABSTRACT

BACKGROUND: The association between health behaviors and the risk of developing hypertension and diabetes is not fully understood. We aimed to examine the association between four health behaviors involved in Life's Essential 8, the American Heart Association's key measures for improving and maintaining cardiovascular health, and the incidence of hypertension and diabetes. METHODS: This observational cohort study used the JMDC Claims Database between 2005 and 2021, which is a health check-up and claims database. We analyzed 2,912,183 participants without a history of hypertension, diabetes, cardiovascular disease, or renal failure. Non-ideal health behaviors included smoking, slow gait speed, eating fast, and poor sleep quality. RESULTS: During 1140 ± 877 days, 201,385 hypertension and 142,156 diabetes events were recorded. In a multivariable Cox regression analysis, the risk of hypertension and diabetes increased with an increasing number of non-ideal health behaviors. The hazard ratios (HRs) (95% confidence interval [CI]) per 1-point increase in non-ideal health behavior components for hypertension and diabetes were 1.11 (1.10-1.11) and 1.08 (1.08-1.09), respectively. Each health behavior was independently associated with the incidence of hypertension and diabetes. A 1-point improvement in health behaviors was associated with a lower risk of developing hypertension (HR 0.94, 95% CI 0.93-0.95) and diabetes (HR 0.95, 95% CI 0.94-0.96). CONCLUSION: Factors that can be substituted for the four health behaviors involved in Life's Essential 8 can stratify the risk of hypertension and diabetes, and improving these health behaviors is useful in preventing hypertension and diabetes in general population.

ABSTRACT

BACKGROUND AND AIMS: This study was conducted to verify whether serum cholinesterase (ChE) is useful in predicting prognosis and discriminating undernutrition status compared to existing low-nutrition indices of blood chemical tests in patients with heart failure (HF). METHODS AND RESULTS: A total of 1617 patients (1204 older patients) with HF who evaluated ChE during hospitalization were recruited for this study. The primary outcome was all-cause death, and multivariate survival analysis was performed. We drew a receiver operating characteristic curve for all-cause death, some undernutrition status, such as low body mass index, thin mid-upper arm circumference, low grip strength, and slow gait speed. The area under the curve was used to compare the predictive ability of ChE with some existing nutritional parameters, such as blood biochemical tests, controlling nutritional status (CONUT), and the geriatric nutritional risk index (GNRI). After adjusting for 29 variables, higher ChE significantly decreased the risk of all-cause death (per 10 increase, hazard ratio: 0.975, 95% confidence interval: 0.952-0.998), and this trend was maintained for older patients (per 10 increase, hazard ratio: 0.972, 95% confidence interval: 0.947-0.997). ChE was moderately correlated with CONUT and GNRI, but the predictive ability for all-cause death was higher for ChE relative to both scores. ChE tended to have an almost consistently high predictive ability compared with other blood biochemical tests. CONCLUSIONS: ChE was associated with all-cause death and an almost consistently higher predictive ability for all-cause death and undernutrition status in comparison to existing blood chemical tests and nutritional scores.

ABSTRACT

In community-dwelling older people, coronavirus disease 2019 (COVID-19) has been reported to be associated with the development of frailty and depressive symptoms. We aimed to investigate whether the spread of COVID-19 is associated with the development of frailty in patients with heart failure (HF). The presence of the multi-domain of frailty in 257 patients with HF was assessed at hospital discharge. The spread of COVID-19 was significantly associated with the development of social frailty and depressive symptoms. Evaluation of these symptoms during hospitalization would support disease management and understanding of their social and psychological conditions.

ABSTRACT

OBJECTIVE: The Short Physical Performance Battery (SPPB) is recommended for evaluating physical performance in patients on hemodialysis (HD). However, the association between SPPB score and long-term health outcomes in these patients remains unclear. We examined the association of SPPB score with all-cause mortality, all-cause hospitalization, and cardiovascular hospitalization in patients on HD. DESIGN AND METHODS: This retrospective cohort study included 326 patients (median age, 68 years; 62% men) who received outpatient HD therapy. These patients were divided into 2 SPPB groups: low (SPPB ≤9) and high (SPPB >9). We investigated the association of SPPB score and their change over time with health outcomes using Cox regression analysis. RESULTS: Low SPPB score was associated with a higher risk for all-cause mortality (hazard ratio [HR]: 3.19, 95% confidence interval [95% CI]: 1.89-5.38), all-cause hospitalization (HR: 2.01, 95% CI: 1.44-2.82), and cardiovascular hospitalization (HR: 2.20, 95% CI: 1.45-3.35). Additionally, change in SPPB score over 1 year was associated with health outcomes. CONCLUSIONS: Lower SPPB score was significantly associated with a higher risk for all-cause mortality, all-cause hospitalization, and cardiovascular hospitalization. The SPPB may be a valuable indicator for risk stratification in patients on HD. Additionally, preventive treatments may be an effective management strategy in limiting the high mortality and hospitalization rates in patients with decreased SPPB score.

ABSTRACT

OBJECTIVE: Although some clinical expert guidelines recommend regular monitoring of serum albumin levels in patients undergoing maintenance hemodialysis, little is known about the serum albumin trajectory patterns over time, and it is unclear how the trajectory change before death. METHODS: We performed this retrospective study using data from 421 patients receiving hemodialysis in a dialysis facility. We divided patients into died and survived groups according to whether they died during the observation period. To compare the albumin trajectories during the observation period between the died and survived groups, linear mixed-effect models and a backward timescale from the year of death or study end were used. RESULTS: During the observation period (median, 5.1 years; maximum, 8.4 years), 115 patients receiving dialysis died. The serum albumin level showed steeper decline 3 years before death in the died group than in the survived group. The difference in albumin between the died and survived groups became apparent 3 years before death (difference, 0.08 g/dL; 95% confidence interval, 0.00-0.15 g/dL; P = .04), and the difference widened over time (difference at 1 year before death, 0.24 g/dL; 95% confidence interval, 0.14-0.33 g/dL; P < .001). Furthermore, in an analysis of albumin trajectories according to cause of death, the albumin level showed a downward trend regardless of the cause of death. CONCLUSION: The serum albumin trajectory differed between patients undergoing hemodialysis who died and who survived, supporting the importance of monitoring the albumin trajectory in clinical practice.

ABSTRACT

BACKGROUND: Although physical activity (PA) decreases dramatically during hospitalization, an effective intervention method has not yet been established for this issue. We recently developed a multiperson PA monitoring system using information and communication technology (ICT) that can provide appropriate management and feedback about PA at the bedside or during rehabilitation. This ICT-based PA monitoring system can store accelerometer data on a tablet device within a few seconds and automatically display a graphical representation of activity trends during hospitalization. OBJECTIVE: This randomized pilot study aims to estimate the feasibility and effect size of an educational PA intervention using our ICT monitoring system for in-hospital patients undergoing cardiac rehabilitation. METHODS: A total of 41 patients (median age 70 years; 24 men) undergoing inpatient cardiac rehabilitation were randomly assigned to 2 groups as follows: wearing an accelerometer only (control) and using both an accelerometer and an ICT-based PA monitoring system. Patients assigned to the ICT group were instructed to gradually increase their step counts according to their conditions. Adherence to wearing the accelerometer was defined as having enough wear records for at least 2 days to allow for adequate analysis during the lending period. An analysis of covariance was performed to compare the change in average step count during hospitalization as a primary outcome and the 6-minute walking distance at discharge. RESULTS: The median duration of wearing the accelerometer was 4 days in the ICT group and 6 days in the control group. Adherence was 100% (n=22) in the ICT group but 83% (n=20) in the control group. The ICT group was more active (mean difference=1370 steps, 95% CI 437-2303) and had longer 6-minute walking distances (mean difference=81.6 m, 95% CI 18.1-145.2) than the control group. CONCLUSIONS: Through this study, the possibility of introducing a multiperson PA monitoring system in a hospital and promoting PA during hospitalization was demonstrated. These findings support the rationale and feasibility of a future clinical trial to test the efficacy of this educational intervention in improving the PA and physical function of in-hospital patients.

ABSTRACT

BACKGROUND: The effectiveness of acute-phase cardiovascular rehabilitation (CR) in intensive care settings remains unclear in patients with cardiovascular disease (CVD). This study aimed to investigate the trends and outcomes of acute-phase CR in the intensive care unit (ICU) for patients with CVD, including in-hospital and long-term clinical outcomes. METHOD: This retrospective cohort study reviewed a total of 1,948 consecutive patients who were admitted to a tertiary academic ICU for CVD treatment and underwent CR during hospitalisation. The endpoints of this study were the following: in-hospital outcomes: probabilities of walking independence and returning home; and long-term outcomes: clinical events 5 years following hospital discharge, including all-cause readmission or cardiovascular events. It evaluated the associations of CR implementation during ICU treatment (ICU-CR) with in-hospital and long-term outcomes using propensity score-matched analysis. RESULTS: Among the participants, 1,092 received ICU-CR, the rate of which tended to increase with year trend (p for trend <0.001). After propensity score matching, 758 patients were included for analysis (pairs of n=379 ICU-CR and non-ICU-CR). ICU-CR was significantly associated with higher probabilities of walking independence (rate ratio, 2.04; 95% CI 1.77-2.36) and returning home (rate ratio, 1.22; 95% CI 1.05-1.41). These associations were consistently observed in subgroups aged >65 years, after surgery, emergency, and prolonged ICU stay. ICU-CR showed significantly lower incidences of all-cause (HR 0.71; 95% CI 0.56-0.89) and cardiovascular events (HR 0.69; 95% CI 0.50-0.95) than non-ICU-CR. CONCLUSIONS: The implementation of acute-phase CR in ICU increased with year trend, and is considered beneficial to improving in-hospital and long-term outcomes in patients with CVD and various subgroups.

ABSTRACT

Despite having a higher risk of cardiovascular disease (CVD), there are currently limited data for stratifying CVD risk among cancer survivors. The purpose of this study was to uncover the relationship of subjective gait speed with incident CVD among cancer survivors.This retrospective observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2021 including 56,589 patients with a prior history of breast, colorectal, or stomach cancer but no history of CVD. Gait speed was evaluated using information from self-reported questionnaires collected during health checkups. The primary endpoint was composite CVD outcome, which included heart failure, myocardial infarction, angina pectoris, and stroke.The median (interquartile range) age was 54 (48-61) years, and 20,981 (37.1%) were male. Among them, 25,933 patients (45.8%) reported fast gait speed. During a mean follow-up period of 1002 ± 803 days, 3,221 composite CVD outcomes were recorded. In multivariate Cox regression analysis, slow gait speed was associated with a higher risk of developing CVD compared with fast gait speed (hazard ratio, 1.14, 95% confidence interval, 1.06-1.22). This association was consistent across a variety of sensitivity analyses.We demonstrated that subjective slow gait speed was associated with a greater risk of CVD development among cancer survivors. This suggests the potential value of gait speed assessment for the CVD risk stratification of cancer patients as well as the clinical importance of maintaining exercise capacity among patients living with cancer.

ABSTRACT

BACKGROUND: The clinical benefit of blood pressure (BP) reduction in individuals with diabetes has not been fully elucidated. We sought to identify the clinical impact of BP reduction on incident cardiovascular disease in people having diabetes and hypertension. METHODS: We conducted a retrospective cohort study including 754,677 individuals (median age 47 years, 75.8 % men) with stage 1/stage 2 hypertension. Participants were categorized using fasting plasma glucose (FPG) at baseline as normal FPG (FPG < 100 mg/dL) (n = 517,372), prediabetes (FPG:100-125 mg/dL) (n = 197,836), or diabetes mellitus (FPG ≥126 mg/dL) (n = 39,469). The primary outcome was heart failure (HF), and the secondary outcomes included ischemic heart disease (IHD) including myocardial infarction and angina pectoris, and stroke. RESULTS: Over a mean follow-up of 1111 ± 909 days, 18,429 HFs, 17,058 IHDs, and 8,795 strokes were recorded. Reduction in BP of< 120/80 mmHg at 1year was associated with a lower risk of developing HF (HR:0.77, 95% CI:0.72-0.82), IHD (HR:0.84, 95% CI:0.79-0.89), and stroke (HR:0.75, 95% CI:0.69-0.82) in individuals with normal FPG, whereas it was not associated with a risk of developing HF (HR:0.98, 95% CI:0.81-1.17) and stroke (HR:0.82, 95% CI:0.62-1.09) in those with DM. Interaction analyses showed that the influence of BP reduction on incident HF was attenuated with people with prediabetes or DM. A multitude of sensitivity analyses confirmed our results. CONCLUSIONS: The association of BP reduction with the risk of developing HF was attenuated with deteriorating glucose tolerance. The optimal management strategy for hypertensive people with prediabetes or DM for the prevention of developing cardiovascular disease (particularly HF) is needed to be established.

ABSTRACT

BACKGROUND: Distinguishable sex differences exist in fat mass and muscle mass. High fat mass and low muscle mass are independently associated with cardiovascular disease (CVD) risk factors in people living with type 2 diabetes; however, it is unknown if the association between fat mass and CVD risk is modified by muscle mass, or vice versa. This study examined the sex-specific interplay between fat mass and muscle mass on CVD risk factors in adults with type 2 diabetes living with overweight and obesity. METHODS: Dual-energy X-ray absorptiometry (DXA) measures were used to compute fat mass index (FMI) and appendicular muscle mass index (ASMI), and participants were separated into high-fat mass vs. low-fat mass and high-muscle mass vs. low-muscle mass. A two-way analysis of covariance (ANCOVA: high-FMI vs. low-FMI by high-ASMI vs. low-ASMI) was performed on CVD risk factors (i.e., hemoglobin A1C [A1C]; high-density lipoprotein cholesterol; low-density lipoprotein cholesterol; triglycerides; systolic and diastolic blood pressure; cardiorespiratory fitness, depression and health related-quality of life [HR-QoL]) at baseline and following a 1-year intensive lifestyle intervention (ILI) for females and males separately, with a primary focus on the fat mass by muscle mass interaction effects. RESULTS: Data from 1,369 participants (62.7% females) who completed baseline DXA were analyzed. In females, there was a fat mass by muscle mass interaction effect on A1C (p = 0.016) at baseline. Post-hoc analysis showed that, in the low-FMI group, A1C was significantly higher in low-ASMI when compared to high-ASMI (60.3 ± 14.1 vs. 55.5 ± 13.5 mmol/mol, p = 0.023). In the high-FMI group, there was no difference between high-ASMI and low-ASMI (56.4 ± 12.5 vs. 56.5 ± 12.8 mmol/mol, p = 0.610). In males, only high-FMI was associated with higher A1C when compared to low-FMI (57.1 ± 14.4 vs. 54.2 ± 12.0 mmol/mol, p = 0.008) at baseline. Following ILI, there were significant fat mass by muscle mass interaction effects on changes in the mental component of HR-QoL in males. CONCLUSION: Considering that A1C predicts future CVD, strategies to lower A1C may be especially important in females with low fat and low muscle mass living with type 2 diabetes. Our results highlight the complicated and sex-specific contribution of fat mass and muscle mass to CVD risk factors.
