World Trade Center workers with asthma and post-traumatic stress disorder perceive airflow limitation more accurately.

BACKGROUND: Post-traumatic stress disorder (PTSD) is a major risk factor for increased asthma morbidity among World Trade Center (WTC) workers. OBJECTIVE: To investigate whether differences in perception of airflow limitation mediate the association of PTSD with worse asthma control in WTC workers. METHODS: We collected data from WTC workers on asthma control (Asthma Control Questionnaire and Asthma Quality of Life Questionnaire) and daily peak expiratory flow (PEF) measures over 6 weeks. Perception of airway limitation was assessed by comparing guessed vs actual PEF values. Post-traumatic stress disorder was diagnosed using the Structured Clinical Interview. We used unadjusted and adjusted models to compare PEF and perception measures in WTC workers with PTSD with those of workers without PTSD. RESULTS: Overall, 25% of 224 participants had PTSD. Post-traumatic stress disorder was associated with worse Asthma Control Questionnaire (2.2±0.8 vs 1.1±0.9, P < .001) and Asthma Quality of Life Questionnaire (3.9±1.1 vs 5.4±1.1, P < .001) scores. Adjusted analyses showed no significant differences in PEF between WTC workers with (351.9±143.3 L/min) and those without PTSD (364.6±131.6 L/min, P = .55). World Trade Center workers with PTSD vs those without PTSD had increased proportion of accurate perception (67.0±37.2% vs 53.5±38.1%, P = .01) and decreased underperception (23.3.0±32.1% vs 38.9±37.5%, P = .004) of airflow limitation during periods of limitation. Similar results were obtained in adjusted analyses. CONCLUSION: This study indicates that differences in perception of airflow limitation may mediate the relationship of PTSD and increased asthma symptoms, given WTC workers with PTSD have worse self-reported asthma control, an increased proportion of accurate perception, and decreased underperception, despite no differences in daily PEF measures.

Connected through movement: a feasibility study of online mindfulness-based dance/movement therapy for older adults with age-related cognitive decline during COVID-19.

OBJECTIVES: Social isolation and loneliness pose significant public health risks, especially among older adults experiencing age-related cognitive decline (ACD). This mixed methods feasibility study explored the potential of an online mindfulness-based dance/movement therapy (M-DMT) program to alleviate loneliness, enhance psychological well-being, and promote physical activity among older adults experiencing ACD during the COVID-19 pandemic. METHOD: Sixteen participants engaged in a 12-week online group M-DMT program. Feasibility was assessed via enrollment and retention rates, attendance, adverse events, credibility/expectancy, participant perceptions, and satisfaction. Qualitative data were collected to capture participants' perspectives on the intervention's usefulness and perceived benefits. The intervention's preliminary impact on loneliness, depression, positive affect, psychological well-being, and physical activity was also examined. RESULTS: The study met all feasibility criteria, with 65% reporting post-intervention improvement. Significant reductions in loneliness and depression, along with enhanced positive affect and psychological well-being, were observed. Though physical activity increased, statistical significance was not achieved. Qualitative feedback highlighted improved social connectedness, overall quality of life, body awareness, kinematic strategy, and satisfaction with the program. CONCLUSION: Online M-DMT holds promise in addressing well-being and loneliness challenges in older adults experiencing ACD. Further research is necessary to validate and expand upon these promising findings.

Muscle Oxygen Saturation Dynamics During Upper-Body Resistance Exercise.

Research examining the changes in muscle oxygen saturation across multiple sets of resistance exercise is limited. The purpose of this study was to describe the physiological response of muscle oxygenation parameters during upper-body resistance exercise and examine the differential effects of relevant participant characteristics on resistance training performance and muscle oxygen saturation dynamics. Sixty-one recreationally trained men (n = 44; 21.8 ± 2.6 years) and women (n = 17; 20.2 ± 1.8 years) completed five-repetition maximum sets of barbell bench presses at a load equal to 75% 1-RM with a 2 min rest interval. Muscle oxygen saturation (SmO2) dynamics within the anterior deltoid were monitored using a portable near-infrared spectroscopy sensor. The percent change in SmO2 (∆%SmO2), the muscle oxygen re-saturation rate (SmO2RecSlope), and the highest measured SmO2 value during recovery periods (SmO2Peak) were measured. Two-way (sex [men, women] x time [sets 1-5]) repeated measures analyses of variance (ANOVA) were performed on muscle saturation variables. To examine the effect of relevant controlling variables, separate analyses of covariance (ANCOVA) with repeated measures were also performed. No differences were seen with ∆%SmO2 across sets. The main effects for sets occurred for SmO2RecSlope, whereby a decline was noted on sets 4 and 5 (p = 0.001) compared to set 1. Additionally, SmO2Peak was the lowest on set 5 (p < 0.001) compared to all other sets. Moreover, body mass (p = 0.013), diastolic blood pressure (p = 0.044), and mean arterial pressure (p = 0.033) for ∆%SmO2 were the only significant covariates noted amongst the muscle oxygenation variables. In conclusion, no sex differences and only a few set differences in muscle oxygen saturation dynamics were seen without employing any covariates. Body mass, diastolic blood pressure, and mean arterial pressure were identified as factors that could influence observed responses.

Four-factor prothrombin complex concentrate use for on-label versus off-label indications: a retrospective cohort study.

This study aimed to characterize the utilization of four-factor prothrombin complex concentrate (4F-PCC) at a tertiary academic medical center and evaluate the incidence of thromboembolic events (TEs) and mortality when used in an on-label versus off-label context. All medical records for consecutive patients having received 4F-PCC over 61-months were retrospectively evaluated. On-label indications for 4F-PCC were defined per FDA guidance, with the remaining indications considered off-label. Three hundred sixty-nine 4F-PCC doses were administered to 355 patients, with 46.6% of administrations classified as off-label. On-label and off-label groups demonstrated similar rates of TEs (16.2% vs. 14%). On-label patients receiving repeated administrations of 4F-PCC or with a post-administration INR ≤ 1.5 had a significantly higher incidence of TE. Off-label patients with a prior history of TE were more likely to develop a TE following 4F-PCC administration. Off-label patients also had a significantly higher 30-day mortality relative to on-label patients (29.1% versus 18.3%). In conclusion, in a large cohort of patients, observed rates of off-label 4F-PCC use were high. Underlying prothrombotic risk factors were predictive of TEs in off-label patients. Moreover, patients receiving off-label 4F-PCC demonstrated higher transfusion rates. Overall, our study findings suggest that the utilization of 4F-PCC in an off-label context may convey a significant risk to patients with uncertain clinical benefits.

Results from an LGBTQ+ Community Health Needs Assessment in Nassau and Suffolk Counties of New York State.

LGBTQ+ individuals experience health care disparities and difficulty accessing affirming care. Little is known regarding the health and experiences among subpopulations of specific sexual orientations and gender identities (SOGI). We implemented the first LGBTQ + health needs assessment survey in Nassau and Suffolk Counties, New York, to assess individuals' health care experiences, behaviors, access to care, and health care needs. The sample (N = 1150) consisted of many SOGI subgroups. Greater than 60% of respondents reported symptoms of chronic depression; over one third reported disrespectful health care experiences; and two thirds experienced verbal harassment. Bisexual/bicurious, pansexual, queer, gender nonconforming and transgender individuals experienced highest rates of mental health concerns and difficulty accessing care. Behavioral health concerns were also high among Black, multiracial, Hispanic, Asian, young adult, and lower-income respondents. Gaining an understanding of unique differences among LGBTQ+ subgroups can guide implementation of services targeting specific subpopulations to improve access to care and reduce disparities.

"How am I going to make it through pregnancy?" A qualitative examination of prenatal maternal stress.

BACKGROUND: Prenatal maternal stress (PNMS) is common among childbearing women, and there is substantial evidence that persistent high levels of stress during pregnancy are associated with adverse birth outcomes and poorer postpartum mental health. Therefore, the purpose of this study was to examine the idiographic experiences of women who experienced elevated PNMS during their current or most recent pregnancy. METHODS: Six focus groups were conducted, and data were collected from 26 women (n = 16 pregnant and n = 10 postpartum) at a large medical center in the United States (US). Data from the semi-structured focus group prompts were analyzed by two independent raters using conventional content analysis21 . RESULTS: Three key themes emerged from the data: (1) Navigating Changing Circumstances, (2) Being a "Good" Mother, and (3) Loss of Control and Autonomy. DISCUSSION: The current study offers one of the first in-depth examinations of the experiences of highly stressed pregnant women using a qualitative approach and identifies stressors rarely described in quantitative research. These findings suggest that women's ability to prioritize their self-care, and receive structural/institutional supports in the workplace and instrumental support at home, and overall health literacy promote successful coping with stress and highlight important future directions for intervention.

Effect of watermelon supplementation on exercise performance, muscle oxygenation, and vessel diameter in resistance-trained men.

INTRODUCTION: Watermelon shows promise as an ergogenic aid due to its high concentration of L-citrulline, vitamins, minerals, and antioxidants. PURPOSE: The purpose of this study was to examine the effect of watermelon supplementation on exercise performance, muscle oxygenation, and vessel diameter. METHODS: In a crossover design fashion, 15 resistance-trained men (22.4 ± 2.9 years; 177.5 ± 7.1 cm; 82.7 ± 11.2 kg) were randomly assigned to supplement with either watermelon juice concentrate (WM; 2.2 g·day-1 L-citrulline) or placebo (PL) for 7 days prior to completing an experimental trial consisting of an isometric mid-thigh pull test and acute bench press protocol. Participants completed two sets of two repetitions at 75% 1 repetition maximum (1-RM) with maximum ballistic intent followed by five repetition-maximum (RM) sets at the same load. Barbell velocity and power were measured via linear position transducer during the first two sets, while volume load and muscle oxygenation were quantified during RM sets. Brachial artery diameter and subjective perception measures were assessed at baseline and immediately pre- and post-exercise. RESULTS: Except for a greater percent change in skeletal muscle oxygenation during WM compared to PL on average and across sets (mean difference = + 4.1%, p = 0.033, BF10 = 2.2-54.5), separate traditional and Bayesian analyses of variance with repeated measures, as well as paired-samples t tests for calculated summary measures, revealed no evidence favoring conditional differences in any measure of performance, perception, or muscle oxygenation. CONCLUSION: Short-term watermelon supplementation does not appear to enhance isometric force production, bench press performance, blood vessel diameter, or muscle oxygenation parameters compared to PL in resistance-trained men.

Comorbid posttraumatic stress disorder and major depressive disorder are associated with asthma morbidity among World Trade Center workers.

BACKGROUND: World Trade Center (WTC) rescue and recovery workers have a high burden of asthma, comorbid posttraumatic stress disorder (PTSD), and major depressive disorder (MDD). PTSD is associated with worse asthma outcomes. OBJECTIVE: In this study, we evaluated whether the relationship between PTSD and asthma morbidity is modified by the presence of MDD. METHODS: We used data from a cohort of WTC workers with asthma. Asthma control (asthma control questionnaire), resource utilization, and quality of life (asthma quality of life questionnaire) were evaluated. We used regression analyses to evaluate the adjusted association of PTSD and MDD with asthma control, resource utilization, and quality of life. RESULTS: Of the study cohort of 293 WTC workers with asthma, 19% had PTSD alone, 2% had MDD alone, and 12% had PTSD and MDD. Adjusted mean differences (95% confidence interval) in asthma control questionnaire scores were 1.32 (0.85-1.80) for WTC workers with PTSD and MDD, 0.44 (0.03-0.84) for those with PTSD alone, and 0.50 (-0.38 to 1.38) for workers with MDD alone compared with those without MDD or PTSD. WTC workers with PTSD and MDD, PTSD alone, and MDD alone had mean (95% confidence interval) adjusted differences in asthma quality of life questionnaire scores of -1.67 (-2.22 to -1.12), -0.56 (-2.23 to -1.12), and -1.21 (-2.23 to -0.18), respectively, compared with workers without MDD or PTSD. Similar patterns were observed for acute resource utilization. CONCLUSION: PTSD and MDD seem to have a synergistic effect that worsens asthma control and quality of life. Efforts to improve asthma outcomes in this population should address the negative impacts of these common mental health conditions.

A Systematic Review of Mindfulness-Based Interventions for Patients with Mild Cognitive Impairment or Dementia and Caregivers.

The aim of this article was to systematically review the quality and efficacy of the current evidence for mindfulness-based interventions (MBIs) in patients with mild cognitive impairment (MCI), patients with dementia (PwD), and their caregivers. We identified 20 randomized controlled trials (RCTs) (11 for patients, 9 for caregivers) published in the last 15 years. Evidence suggested that MBIs are highly acceptable and credible treatments for patients with MCI, PwD and caregivers. Specifically, for PwD, the results indicated that the magnitude of post-treatment effects of MBIs are in the medium to large range for psychosocial outcomes, and in the small to medium range for cognitive functioning; however, treatment effects on dementia biomarkers were mixed, ranging from small to large, depending on the outcome measure. Findings also evidenced salutary effects of MBIs for caregivers of PwD, with post-treatment effects ranging from medium to large for caregiver stress and burden and large effects for quality of life, and mixed outcomes for cognitive functioning, with effects in the small to large range. However, confidence in these findings is relatively limited due to methodological limitations, especially in terms of poor consistency in intervention strategies, outcome measures, and other key criteria across studies. To better assess the value of MBIs for these populations and optimize treatment outcomes, we recommend further research with improved study methodology (e.g., multi-method assessment, universal criterion and outcome measures, use of active control groups, larger sample sizes, long-term follow-up) to replicate current findings and enhance our understanding of underlying treatment mechanisms of MBIs.

The utility of therapeutic plasma exchange in Hyperviscosity syndrome associated with juvenile rheumatoid arthritis: A case report.

Hyperviscosity syndrome (HVS) is a life-threatening syndrome caused by high concentrations of large plasma proteins like IgM, rheumatoid factor, and other immune complexes, leading to increased blood viscosity and symptoms such as visual abnormalities, neurological impairment, bleeding diathesis, and thrombosis. While Waldenström's macroglobulinemia accounts for 80% to 90% of cases, HVS may develop in other clinical settings characterized by elevations in plasma proteins. Limited evidence currently exists describing the safety and efficacy of therapeutic plasma exchange (TPE) for the management of HVS secondary to non-neoplastic conditions. We report a case of recurrent HVS associated with juvenile rheumatoid arthritis and Felty syndrome that demonstrated improvement in clinical symptoms following initiation of TPE. These findings suggest that TPE may be utilized as an adjunct treatment option in patients with HVS secondary to autoimmune disorders.

The disaster worker resiliency training program: a randomized clinical trial.

OBJECTIVES: Disaster workers are at elevated risk for mental health problems as a result of trauma exposures during response efforts. One possible way to prevent mental health problems is to build-up coping resources that promote resilience to the effects of disaster work. The primary aim of this study was to evaluate the efficacy of a resilience building workshop, the Disaster Worker Resiliency Training Program (DWRT), in disaster workers previously exposed to Hurricane Sandy. METHODS: Disaster workers (N = 167) were randomly assigned to the DWRT workshop (n = 78) or a waitlist (n = 89). Workers completed self-report measures on healthy lifestyle behaviors, perceived stress, depression, and Posttraumatic Stress Disorder (PTSD) symptoms at baseline and 3-month follow-up. They also completed a measure assessing subsequent trauma-exposure between the baseline and 3-month post-intervention. RESULTS: Participants in the workshop condition, as compared to those in a waitlist control, reported significantly greater improvements from pre-intervention (T1) to 3-month follow-up (T2) in healthy lifestyle behaviors (η2 = .03; p = .03), stress management (η2 = .03, p = .04), and spiritual growth (η2 = .03, p = .02). Among participants reporting subsequent trauma exposures between T1 and T2  (n = 101), participants in the waitlist condition, were more likely to report significant increases in perceived stress (η2 = .07, p < .01), PTSD (η2 = .05, p = .03), and depression (η2 = .07, p < .01) symptoms. CONCLUSIONS: Participation in the resilience workshop promoted engagement in positive health behaviors and reduced the incidence of mental health symptoms, especially when administered prior to a repeat trauma exposure. Further research is needed to evaluate the long-term health effects of participation in the program.

Acute Effect of Citrulline Malate on Repetition Performance During Strength Training: A Systematic Review and Meta-Analysis.

Citrulline malate (CitMal) is a dietary supplement that is suggested to enhance strength training performance. However, there is conflicting evidence on this matter. Thus, the purpose of this meta-analysis was to determine whether supplementing with CitMal prior to strength training could increase the total number of repetitions performed before reaching voluntary muscular failure. A systematic search was conducted wherein the inclusion criteria were double-blind, placebo-controlled studies in healthy participants that examined the effect of CitMal on repetitions to failure during upper body and lower body resistance exercises. The Hedges's g standardized mean differences (SMD) between the placebo and CitMal trials were calculated and used in a random effect model. Two separate subanalyses were performed for upper body and lower body exercises. Eight studies, including 137 participants who consisted of strength-trained men (n = 101) and women (n = 26) in addition to untrained men (n = 9), fulfilled the inclusion criteria. Across the studies, 14 single-joint and multijoint exercises were performed with an average of 51 ± 23 total repetitions during 5 ± 3 sets per exercise at ∼70% of one-repetition maximum. Supplementing with 6-8 g of CitMal 40-60 min before exercise increased repetitions by 3 ± 5 (6.4 ± 7.9%) compared with placebo (p = .022) with a small SMD (0.196). The subanalysis for the lower body resulted in a tendency for an effect of the supplement (8.1 ± 8.4%, SMD: 0.27, p = .051) with no significant effect for the upper body (5.7 ± 8.4%, SMD: 0.16, p = .131). The current analysis observed a small ergogenic effect of CitMal compared with placebo. Acute CitMal supplementation may, therefore, delay fatigue and enhance muscle endurance during high-intensity strength training.

Comparison of V̇o2peak and V̇o2max at Different Sampling Intervals in Collegiate Wrestlers.

ABSTRACT: Sell, KM, Ghigiarelli, JJ, Prendergast, JM, Ciani, GJ, Martin, J, and Gonzalez, AM. Comparison of V̇o2peak and V̇o2max at different sampling intervals in collegiate wrestlers. J Strength Cond Res 35(10): 2915-2917, 2021-The purpose of this study was to determine the difference in the highest oxygen uptake (V̇o2peak) achieved during a maximal effort graded exercise test (GXT) in 20 NCAA Division I male wrestlers using breath-by-breath (BbB) values to the maximal uptake averaged across different time- and breath-based oxygen consumption sampling intervals (V̇o2max). Given the need for aerobic fitness and anaerobic power in wrestling, the accurate determination of V̇o2max is imperative if it is to be used to identify current aerobic fitness and consequently guide sport-specific training programs to address weaknesses in this area. Each subject completed a cycle ergometer GXT during which BbB data were collected via indirect calorimetry and V̇o2peak determined as the highest value. V̇o2max was considered as the average value of 3-s, 5-s, 10-s, 20-s, and 30-s sampling, and 3-b, 7-b, and 11-b sampling during the GXT. Results show that the BbB V̇o2peak was significantly higher than the 5-s, 10-s, 20-s, 30-s, and 11-b (p < 0.05). The 3-b V̇o2max was significantly higher than the 20-s and 30-s V̇o2max values (p < 0.05). The underestimation of V̇o2peak for each time-based interval sampling approach compared with BbB V̇o2peak is consistent with previous research, but the comparison of BbB data to breath-based interval sampling has not been widely addressed in prior research. The use of a 7-b sampling interval for the determination of V̇o2max may be a promising approach to minimize the systematic errors associated with BbB or less frequent sampling intervals, but future research is needed to further support its application with elite athletic populations such as those in the current study.

Three months of informational trends in COVID-19 across New York City.

In the midst of widespread community transmission of coronavirus disease 2019 (COVID-19) in New York, residents have sought information about COVID-19. We analyzed trends in New York State (NYS) and New York City (NYC) data to quantify the extent of COVID-19-related queries. Data on the number of 311 calls in NYC, Google Trend data on the search term 'Coronavirus' and information about trends in COVID-19 cases in NYS and the USA were compiled from multiple sources. There were 1228 994 total calls to 311 between 22 January 2020 and 22 April 2020, with 50 845 calls specific to COVID-19 in the study period. The proportion of 311 calls related to COVID-19 increased over time, while the 'interest over time' of the search term 'Coronavirus' has exponentially increased since the end of February 2020. It is vital that public health officials provide clear and up-to-date information about protective measures and crucial communications to respond to information-seeking behavior across NYC.

COVID-19: Postmortem Diagnostic and Biosafety Considerations.

As a result of the 2019 novel human coronavirus (COVID-19) global spread, medical examiner/coroner offices will inevitably encounter increased numbers of COVID-19-infected decedents at autopsy. While in some cases a history of fever and/or respiratory distress (eg, cough or shortness of breath) may suggest the diagnosis, epidemiologic studies indicate that the majority of individuals infected with COVID-19 develop mild to no symptoms. Those dying with-but not of-COVID-19 may still be infectious, however. While multiple guidelines have been issued regarding autopsy protocol in cases of suspected COVID-19 deaths, there is some variability in the recommendations. Additionally, limited recommendations to date have been issued regarding scene investigative protocol, and there is a paucity of publications characterizing COVID-19 postmortem gross and histologic findings. A case of sudden unexpected death due to COVID-19 is presented as a means of illustrating common autopsy findings, as well as diagnostic and biosafety considerations. We also review and summarize the current COVID-19 literature in an effort to provide practical evidence-based biosafety guidance for medical examiner-coroner offices encountering COVID-19 at autopsy.

Effects of Citrulline Supplementation on Exercise Performance in Humans: A Review of the Current Literature.

Gonzalez, AM and Trexler, ET. Effects of citrulline supplementation on exercise performance in humans: A review of the current literature. J Strength Cond Res 34(5): 1480-1495, 2020-L-citrulline, a nonessential amino acid found primarily in watermelon, has recently garnered much attention for its potential to augment L-arginine bioavailability, nitric oxide production, and exercise performance. Over the past decade, L-citrulline has received considerable scientific attention examining potentially ergogenic properties for both aerobic and anaerobic exercise performance. Thus, the purpose of this article is to summarize the theoretical rationale behind L-citrulline supplementation and to comprehensively review the available scientific evidence assessing the potential ergogenic value of L-citrulline supplementation on vascular function and exercise performance in humans. In addition, research that has investigated the potential synergistic effects of L-citrulline with other dietary ingredients (e.g., arginine, antioxidants, nitrates, and branched-chain amino acids) is reviewed. Oral L-citrulline and citrulline malate supplementation have shown to increase plasma citrulline and arginine concentrations, along with total nitrate and nitrite concentrations. Although blood flow enhancement is a proposed mechanism for the ergogenic potential of L-citrulline, evidence supporting acute improvements in vasodilation and skeletal muscle tissue perfusion after supplementation is scarce and inconsistent. Nevertheless, several studies have reported that L-citrulline supplementation can enhance exercise performance and recovery. Given the positive effects observed from some investigations, future studies should continue to investigate the effects of both acute and chronic supplementation with L-citrulline and citrulline malate on markers of blood flow and exercise performance and should seek to elucidate the mechanism underlying such effects.

Effect of Multi-Ingredient Preworkout Supplementation on Repeated Sprint Performance in Recreationally Active Men and Women.

Gonzalez, AM, Pinzone, AG, Bram, J, Salisbury, JL, Lee, S, and Mangine, GT. Effect of multi-ingredient preworkout supplementation on repeated sprint performance in recreationally active men and women. J Strength Cond Res 34(4): 918-923, 2020-The purpose of this investigation was to examine the effects of acute supplementation of a multi-ingredient preworkout supplement (MIPS), containing a proprietary blend of ancient peat and apple extracts, creatine monohydrate, taurine, ribose, and magnesium, on sprint cycling performance. Seventeen recreationally active men and women (23.2 ± 5.9 years; 172.9 ± 14.3 cm; 82.4 ± 14.5 kg) underwent 2 testing sessions administered in a randomized, counterbalanced, double-blind fashion. Subjects were provided either MIPS or placebo (PL) one hour before performing a sprint cycling protocol, which consisted of ten 5-second "all-out" sprints interspersed by 55 seconds of unloaded pedaling. Average power (PAVG), peak power (PPK), average velocity (VAVG), and distance covered were recorded for each sprint. Separate linear mixed models revealed decrements (p < 0.05) compared to the first sprint in PAVG (75-229 W) and PPK (79-209 W) throughout all consecutive sprints after the initial sprint during PL. Likewise, diminished (p ≤ 0.029) VAVG (3.37-6.36 m·s) and distance covered (7.77-9.00 m) were noted after the third and fifth sprints, respectively, during PL. By contrast, during MIPS, only VAVG decreased (2.34-5.87 m·s, p ≤ 0.002) on consecutive sprints after the first sprint, whereas PAVG and PPK were maintained. In addition, a significant decrease (p = 0.045) in distance covered was only observed on the ninth sprint during MIPS. These data suggest that recreational athletes who consumed the MIPS formulation, one hour before a repeated sprinting session on a cycle ergometer, better maintained performance compared with PL.

Differential effect of Hurricane Sandy exposure on PTSD symptom severity: comparison of community members and responders.

OBJECTIVES: To evaluate whether the association between Hurricane Sandy exposures and post-traumatic stress disorder (PTSD) symptom severity was greater for exposed community members compared with responders. METHODS: Data were analysed from three existing studies with similar methodologies (N=1648): two community studies, Leaders in Gathering Hope Together (n=531) and Project Restoration (n=763); and the Sandy/World Trade Center Responders Study (n=354). Sandy-related PTSD symptoms were measured using the PTSD checklist-specific traumatic event and dichotomised as elevated (>30) versus low/no (<30) PTSD symptoms. Sandy exposures were measured with a summed checklist. Multivariable logistic regression was performed to evaluate the differential effect of exposures on PTSD by responder status, adjusting for demographics and time elapsed since Sandy. RESULTS: Responders were somewhat older (50.5 years (SD=8.3) vs 45.8 years (SD=20.0)), more likely to identify as white (92.4% vs 48.1%) and were male (90.7% vs 38.4%). Responders were less likely to have elevated PTSD symptoms than community members (8.6% vs 31.1%; adjusted OR=0.28, 95% CI 0.17 to 0.46). While exposure was significantly related to elevated PTSD status, the effects were similar for responders and community members. CONCLUSIONS: Responders appear to be more resilient to PTSD symptoms post-Sandy than community members. Understanding the mechanisms that foster such resilience can inform interventions aimed at populations that are more vulnerable to experiencing PTSD after natural disasters.

The Relaxation Response Resiliency Program (3RP) in Patients with Headache and Musculoskeletal Pain: A Retrospective Analysis of Clinical Data.

BACKGROUND: Headache and musculoskeletal pain are associated with both physical and mental health symptoms, which together are mutually reinforcing. Addressing mental and physical health symptoms (including pain) concomitantly may provide an effective and efficient way to improve outcomes in this population. We tested an evidence-based, eight-session multimodal group program, the Relaxation Response Resiliency Program (3RP), in patients with headache and musculoskeletal pain. A total of 109 adults (30 with headaches, 79 with musculoskeletal pain). METHODS: Participant were 109 adults (30 with headaches, 79 with musculoskeletal pain) referred by their medical doctor, who completed a battery of questionnaires before and after completion of the 3RP. RESULTS: On average, patients with headache and musculoskeletal pain had higher pretreatment scores for anxiety, depression, and somatization symptoms than the nonpatient normative sample for the Symptom Checklist 90-Revised. Significant improvements were identified from pre- to post-treatment in all mental health symptoms (moderate to large effects) and frequency of pain and co-occurring physical health symptoms (small to moderate effects). Patients also reported significant decreases in degree of discomfort and life interference, which were relatively more modest in the musculoskeletal pain group compared with the headache group. CONCLUSIONS: Overall, results of this study suggest that the 3RP may be an effective treatment for reducing pain and psychological symptoms in patients with headaches and musculoskeletal pain. Future work is needed to evaluate the 3RP via a randomized clinical trial in these patient populations.
