The Feasibility and Efficacy of Warrior Health and Fitness: A 3-Month Fitness and Nutrition Program for Veterans.

INTRODUCTION: Veterans are at risk for mental and physical health problems but may not seek traditional health care services. Wellness-based interventions, including exercise and nutrition, have been associated with improvements in physical and mental health among this population. This study explores the acceptability, feasibility, and efficacy of a 3-month health and fitness program for veterans. MATERIALS AND METHODS: Participants in 2 time-based cohorts from 2019 to 2023 (cohort 1: n = 261; cohort 2: n = 256) were cleared by a physician to participate. Participants then completed a fitness test and self-reported surveys (e.g., quality of life, sleep, and pain) before and after the 3-month program. Participants were recruited to participate at one of three sites: Boston, MA Fort Myers, FL, or Tampa, FL. The 3-month program consisted of weekly, supervised group fitness and one-on-one sessions, nutritional consultations, yoga, and other wellness activities. Primary program outcomes were measured by fitness assessments, self-report surveys, program completion, and program satisfaction. Fitness assessments included measures of weight, body mass index, grip strength, waist to hip ratio, body fat, lean mass, fat mass, heart rate, and blood pressure (BP). Self-report measures included quality of life, depression, loneliness, sleep quality, pain intensity, and pain interference. RESULTS: In cohort 1, significant improvements were found for measures of weight (P = .01), left-handed grip strength (P < .01), body fat percent (P < .01), and quality of life (P < .01). In cohort 2, significant improvements were found for measures of waist:hip ratio (P = .02), right and left-handed grip strength (P < .01), body mass index (P = .02), body fat percent (P < .01), and quality of life (P = .02). For both cohorts, pain intensity (cohort 1: P = .01, cohort 2: P < .001) and pain interference (cohort 1: P = .02, cohort 2: P < .001) increased significantly. CONCLUSIONS: These data suggest that a 3-month health and fitness program for veterans is acceptable and feasible and may improve physical and mental health outcomes. Considerations for program retention and assessment completion are discussed.

Multiplex array analysis of serum cytokines offers minimal predictive value for cognitive function in the subacute phase after stroke.

Objective: The effects of inflammation on post-stroke cognitive function are still unclear. This study investigated the correlation between the Th17-related cytokines in peripheral blood and post-stroke cognitive function after ischemic stroke in the subacute phase. Design: A retrospective cohort study. Setting: Academic acute inpatient rehabilitation facility. Participants: One hundred and fourteen patients with first ischemic stroke were categorized as the poor cognitive recovery group (n = 58) or good cognitive recovery group (n = 56) based on their cognitive MRFS efficiency. Interventions: All subjects received routine physical, occupational, and speech-language pathology therapy. Main outcome measures: Serum cytokines/chemokine (IL-1 ß, IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-12p70, IL-13, IL-15, IL-17A, IL-17E, IL-17F, IL-21, IL-22, IL-23, IL-27, IL-28A, IL-31, IL-33, GM-CSF, IFN-γ, MIP-3 α, TNF-α, and TNF-ß) levels were measured in duplicate using Human Th17 magnetic bead panel and multiplex array analysis (Luminex-200 system). The primary functional outcome was a gain in functional independence measure (FIM) cognitive subscore at discharge. The secondary outcome measures were FIM total score at discharge, length of stay in the hospital, and discharge destination. Cognitive Montebello Rehabilitation Factor Score (MRFS) and cognitive MRFS efficiency were calculated. Demographic and clinical characteristics were obtained from the medical record. Results: The good cognitive recovery group had an interesting trend of higher IL-13 than the poor cognitive recovery group (good cognitive recovery group 257.82 ± 268.76 vs. poor cognitive recovery group 191.67 ± 201.82, p = 0.049, unit: pg/ml). However, Pearson's correlation analysis showed no significant correlation between cytokine levels and gain of cognition, cognitive MRFS, or cognitive MRFS efficiency. Receiver operating characteristic (ROC) analysis of cytokines also suggested a low accuracy of prediction as a predictor for post-stroke cognitive recovery improvement. Conclusion: Our preliminary findings suggested that the level of serum cytokines had minimal predictive value for the recovery of cognitive function during the subacute inpatient rehabilitation after stroke.

Anticoagulation Is Associated with Decreased Inferior Vena Cava Filter-Related Complications in Patients with Metastatic Carcinoma.

OBJECTIVES: Patients with metastatic carcinoma and venous thromboembolism commonly have contraindications to anticoagulation that prompt the use of retrievable inferior vena cava filters. The aim of this study was to compare the pattern of inferior vena cava filter use, anticoagulation management, and development of inferior vena cava filter-related complications in patients with localized versus metastatic carcinoma. METHODS: We conducted a retrospective cohort study of inferior vena cava filter use at a tertiary referral hospital between January 1, 2009, and December 31, 2011. Including only patients with cancer and carcinomas, both metastatic and localized, we recorded the indications for inferior vena cava filter, postfilter practices including anticoagulation use, filter retrieval rates, and filter-related complications. RESULTS: Overall, 154 patients with carcinoma underwent inferior vena cava filter placement. Basic demographics and indication for filter placement were similar between the metastatic and localized groups. Metastatic patients had more filter-related complications (25% vs 11%, P = .03) and underwent filter retrieval less often (31% vs 58%, P = .01). Time to reinitiating anticoagulation was longer in metastatic patients (5.5 vs 2 days, P = .05). In multivariate analysis, metastatic disease was associated with reduced inferior vena cava filter retrieval (odds ratio, 0.3; P = .003). Anticoagulation use was associated with a lower rate of filter-related complications (odds ratio, 0.3; P = .005). CONCLUSIONS: Patients with metastatic carcinoma with an indwelling inferior vena cava filter had a higher rate of filter-related complications, a lower filter retrieval rate, and a greater median time to initiating anticoagulation. When possible, early reinitiation of anticoagulation may reduce inferior vena cava filter-related complications.

A comparison of patients diagnosed with pulmonary embolism who are ≥65 years with patients <65 years.

Recent studies have highlighted differences in how older patients respond to high-risk pulmonary embolism (PE) and treatment. However, guidelines for PE risk stratification and treatment are not based on age, and data are lacking for older patients. We characterized the impact of age on clinical features, risk stratification, treatment, and outcomes in a sample of patients with PE in the emergency department. We performed an observational cohort study of 547 consecutive patients with PE in the emergency department from 2005 to 2011 in an urban tertiary hospital. We used bivariate proportions and multivariable logistic regression to compare clinical presentation, risk category, treatment, and outcomes in patients ≥65 years with those <65 years. The mean age was 58 ± 17 years, 276 (50%) were women, and 210 (38%) were ≥65 years. PE was more severe in patients ≥65 years (massive 14% vs 5%, submassive 48% vs 25%, and low risk 38% vs 70%, p <0.0001), with submassive PE being the most common presentation in patients ≥65 years. However, subanalysis removing natriuretic peptides from the definition of submassive PE negated this finding. Treatment with parenteral anticoagulation (88% vs 90%, p = 0.32), thrombolytic therapy (5% vs 4%, p = 0.87), and inferior vena cava filter (4% vs 4%, p = 0.73) were similar among age groups. Patients ≥65 years had higher 30-day mortality (11% vs 3%, p <0.001). In conclusion, patients ≥65 years present with more severe PE and have higher mortality, although treatment patterns were similar to younger patients. Age-specific guideline definitions of submassive PE may better identify high-risk patients.

Inferior vena cava filter usage, complications, and retrieval rate in cancer patients.

BACKGROUND: Venous thromboembolism contributes significantly to morbidity and mortality in cancer patients. Because cancer patients frequently have contraindications to anticoagulation, inferior vena cava filters are commonly placed. The use, safety, and retrieval of retrievable inferior vena cava filters in cancer patients have not been well studied. METHODS: A retrospective review of retrievable inferior vena cava filter use at a tertiary referral hospital was conducted between January 1, 2009 and December 31, 2011. Indications for inferior vena cava filter placement, anticoagulation practices, complications, filter retrieval, and patient outcomes were analyzed for patients with and without active cancer and for cancer subtypes, including localized and metastatic cases. RESULTS: Of 666 patients receiving retrievable inferior vena cava filters during this time period, 247 (37.1%) had active cancer. Of these, 151 (22.7%) had carcinoma, 92 (13.8%) had sarcoma, and 115 (17.3%) had metastatic disease. Overall, follow-up was available for a median of 401.0 (interquartile range: 107.5-786.5) days. Indwelling filter-related complications occurred in 19.8% of patients without cancer and 17.7% with an active cancer (P = .50). Patients with cancer were less likely to have the filter retrieved (28.0% vs 42.0%, P < .001). In multivariable analysis, cancer was not associated with filter-related complications but was associated with a lower rate of filter retrieval. CONCLUSIONS: In a modern cohort of patients undergoing retrievable inferior vena cava filter placement, active diagnosis of cancer is not associated with a significant increase in filter-related complications, but is associated with a reduced rate of filter retrieval.

Effect of delayed inferior vena cava filter retrieval after early initiation of anticoagulation.

Retrievable inferior vena cava filters (IVCFs) were designed to provide temporary protection from pulmonary embolism in high-risk situations. However, little is known about their effectiveness, and many remain permanently implanted, leading to potential complications. The aim of this study was to determine patient characteristics, indications for IVCF placement, retrieval rates, complications, and post-IVCF anticoagulation (AC) practices in patients who have received IVCFs. A retrospective review of IVCF use by 3 specialty groups from January 1, 2009, to December 31, 2011, was conducted at a tertiary referral center. Indications for IVCF, procedural success and complications, post-IVCF AC practices, and patient outcomes were assessed. Seven hundred fifty-eight IVCFs were placed. Follow-up was available for 688 patients (90.7%) at a median of 342.0 days (interquartile range 81.5 to 758.0). Indications for IVCF placement included contraindication to AC in the presence of acute venous thromboembolism (n = 287 [41.7%]) and prophylaxis (n = 235 [34.2%]). Insertion-related complications occurred in 28 patients (4.1%). After IVCF placement, adequate AC was initiated in 454 patients (66.0%) <3.0 days (interquartile range 0 to 13.0) after insertion, but the overall retrieval rate was only 252 of 688 (36.6%) within a median of 134.0 days (interquartile range 72.50 to 205.8). Significant IVCF-related complications occurred in 122 patients (17.7%) within 32 days (interquartile range 13.0 to 116.8). The most common complication (72 of 131 [55.0%]) was deep vein thrombosis. In conclusion, in a large, modern cohort of patients receiving retrievable IVCFs for a variety of indications by various specialties, IVCF insertion remains safe. However, many patients have IVCF-related complications, and often, even when IVCFs are retrieved, there is a delay between AC and retrieval. Quality improvement initiatives that facilitate the expeditious retrieval of IVCF are needed.

Incidence of venous thromboembolism in asymptomatic family members who are carriers of factor V Leiden: a prospective cohort study.

In a prospective cohort study, we assessed the incidence of spontaneous and risk period-related venous thromboembolism (VTE) in asymptomatic family members of patients who experienced VTE and had the factor V Leiden mutation. In all, 561 family members of 131 probands were included, 313 of whom were carriers (299 heterozygous and 14 homozygous) and 248 of whom were noncarriers of the factor V Leiden mutation. Average follow-up was 4 years (range, 4 months-6 years). There were 1255 and 984 observation-years of follow-up in carriers and noncarriers, respectively. Eight episodes of VTE occurred in heterozygous carriers, resulting in an annual incidence of 0.67% (95% confidence interval [CI], 0.29-1.33). Two events occurred in the absence of associated risk factors, determining an annual incidence of spontaneous VTE of 0.17% (95% CI, 0.02-0.6). Only one VTE (risk period-related) occurred in noncarriers, with an annual incidence of 0.1% (95% CI, 0.003-0.56). Relative risk for VTE in heterozygous carriers compared with noncarriers of the factor V Leiden mutation was 6.6 (95% CI, 1.1-39.8). Risk period-related VTE occurred with an incidence of 18% and 5% per risk period in heterozygous carriers and in noncarriers, respectively. Thus, the low rate of VTE in asymptomatic family members carrying the mutation did not justify continuous anticoagulant prophylaxis. Screening families of symptomatic probands with the factor V Leiden mutation has the potential to identify those asymptomatic carriers who might benefit from thromboprophylaxis during risk periods.
