RESUMO

BACKGROUND: As the number of total shoulder arthroplasty (TSA) procedures increases, there is a growing interest in improving patient outcomes, limiting costs, and optimizing efficiency. One approach has been to transition these surgeries to an outpatient setting. Therefore, the purpose of this study was to conduct an age-stratified analysis comparing the 90-day postoperative outcomes of primary TSA in the same-day discharge (SDD) and inpatient (IP) settings with a specific focus on the super-elderly. METHODS: This retrospective study included all patients who underwent primary anatomic or reverse TSA between January 2018 and December 2021 in ambulatory and IP settings. The outcome measures included length of stay (LOS), complications, hospital charges, emergency department (ED utilization), readmissions, and reoperations within 90 days following TSA. Patients with LOS ≤8 hours were considered as SDD, and those with LOS >8 hours were considered as IP. P < .05 was considered statistically significant. RESULTS: There were 121 and 174 procedures performed in SDD and IP settings, respectively. There were no differences in comorbidity indices between the SDD and IP groups (American Society of Anesthesiologists score P = .12, Elixhauser Comorbidity Index P = .067). The SDD cohort was younger than the IP group (SDD 67.0 years vs. 73.0 IP years, P < .001), and the SDD group higher rate of intraoperative tranexamic acid use (P = .015) and lower estimated blood loss (P = .009). There were no differences in 90-day overall minor (P = .20) and major complications (P = 1.00), ED utilization (P = .63), readmission (P = .25), or reoperation (P = .51) between the SDD and IP groups. When stratified by age, there were no differences in overall major (P = .80) and minor (P = .36) complications among the groups. However, the LOS was directly correlated with increasing age (LOS = 8.4 hours in ≥65 to <75-year cohort vs. LOS = 25.9 hours in ≥80-year cohort; P < .001). There were no differences in hospital charges between SDD and IP primary TSA in all 3 age groups (P = .82). CONCLUSION: SDD TSA has a shorter LOS without increasing postoperative major and minor complications, ED encounters, readmissions, or reoperations. Older age was not associated with an increase in the complication profile or hospital charges even in the SDD setting, although it was associated with increased LOS in the IP group. These results suggest that TSA can be safely performed expeditiously in an outpatient setting.

RESUMO

BACKGROUND: Several skeletal maturity systems allow for accurate skeletal age assessment from a wide variety of joints. However, discrepancies in estimates have been noted when applying systems concurrently. The aims of our study were to (1) compare the agreement among 8 different skeletal maturity systems in modern pediatric patients and (2) compare these discrepancy trends qbetween modern and historic children. METHODS: We performed a retrospective (January 2000 to May 2022) query of our picture archiving and communication systems and included peripubertal patients who had at least two radiographs of different anatomic regions obtained ≤3 months apart for 8 systems: (1) proximal humerus ossification system (PHOS), (2) olecranon apophysis ossification staging system (OAOSS), (3) lateral elbow system, (4) modified Fels wrist system, (5) Sanders Hand Classification, (6) optimized oxford hip system, (7) modified Fels knee system, and (8) calcaneal apophysis ossification staging system (CAOSS). Any abnormal (ie, evidence of fracture or congenital deformity) or low-quality radiographs were excluded. These were compared with a cohort from a historic longitudinal study. SEM skeletal age, representing the variance of skeletal age estimates, was calculated for each system and used to compare system precision. RESULTS: A total of 700 radiographs from 350 modern patients and 954 radiographs from 66 historic patients were evaluated. In the modern cohort, the greatest variance was seen in PHOS (SEM: 0.28 y), Sanders Hand (0.26 y), and CAOSS (0.25 y). The modified Fels knee system demonstrated the smallest variance (0.20 y). For historic children, the PHOS, OAOSS, and CAOSS were the least precise (0.20 y for all). All other systems performed similarly in historic children with lower SEMs (range: 0.18 to 0.19 y). The lateral elbow system was more precise than the OAOSS in both cohorts. CONCLUSIONS: The precision of skeletal maturity systems varies across anatomic regions. Staged, single-parameter systems (eg, PHOS, Sanders Hand, OAOSS, and CAOSS) may correlate less with other systems than those with more parameters. LEVEL OF EVIDENCE: Level III-retrospective study.

RESUMO

BACKGROUND: Prospective investigations on the risk of cardiovascular disease among youth with perinatally acquired human immunodeficiency virus (PHIV) in sub-Saharan Africa are lacking. METHODS: A prospective observational cohort study was performed in 101 youth (aged 10-18 years) with PHIV and 97 who were human immunodeficiency virus (HIV) uninfected (HIV-), from 2017 to 2021 at the Joint Clinical Research Center in Uganda. Participants with PHIV were receiving antiretroviral therapy (ART) and had HIV-1 RNA levels ≤400 copies/mL. The common carotid artery intima-media thickness (IMT) and pulse wave velocity (PWV) were evaluated at baseline and at 96 weeks. Groups were compared using unpaired t-test, and potential predictors of IMT and PWV were assessed using quantile regression. RESULTS: Of the 198 participants recruited at baseline, 168 (89 with PHIV, 79 HIV-) had measurements at 96 weeks. The median age (interquartile range) age was 13 (11-15) years; 52% were female, and 85% had viral loads <50 copies/mL that remained undetectable at week 96. The baseline mean common carotid artery IMT was slightly higher in participants with PHIV compared with controls (P < .01), and PWV did not differ between groups (P = .08). At week 96, IMT decreased and PWV increased in the PHIV group (P ≤ .03); IMT increased in the HIV- group (P = .03), with no change in PWV (P = .92). In longitudinal analyses in those with PHIV, longer ART duration was associated with lower PWV (ß = .008 [95% confidence interval, -.008 to .003]), and abacavir use with greater IMT (ß = .043 [.012-.074]). CONCLUSIONS: In healthy Ugandan youth with PHIV, virally suppressed by ART, the common carotid artery IMT did not progress over 2 years. Prolonged and early ART may prevent progression of subclinical vascular disease, while prolonged use of abacavir may increase it.

RESUMO

BACKGROUND: Uncontrolled blood pressure (BP) rates are persistently high among African Americans with hypertension. Although self-management is critical to controlling BP, little is known about the brain-behavior connections underlying the processing of health information and the performance of self-management activities. OBJECTIVES: In this pilot study, we explored the associations among neural processing of two types of health information and a set of self-management cognitive processes (self-efficacy, activation, decision-making, and hypertension knowledge) and behaviors (physical activity, dietary intake, and medication taking) and health status indicators (BP, health-related quality of life, anxiety, and depression). METHODS: Using a descriptive cross-sectional design, 16 African Americans with uncontrolled hypertension (mean age = 57.5 years, 68.8% women) underwent functional magnetic resonance imaging to assess activation of two neural networks, the task-positive network and the default mode network, and a region in the ventromedial prefrontal cortex associated with emotion-focused and analytic-focused health information. Participants completed self-reports and clinical assessments of self-management processes, behaviors, and health status indicators. RESULTS: Our hypothesis that neural processing associated with different types of health information would correlate with self-management cognitive processes and behaviors and health status indicators was only partially supported. Home diastolic BP was positively associated with ventromedial prefrontal cortex activation ( r = .536, p = .09); no other associations were found among the neural markers and self-management or health status variables. Expected relationships were found among the self-management processes and behaviors and health status indicators. DISCUSSION: To advance our understanding of the neural processes underlying health information processing and chronic illness self-management, future studies are needed that use larger samples with more heterogeneous populations and additional neuroimaging techniques.

RESUMO

BACKGROUND: For the 720 000 Americans expected to experience a new acute cardiac event this year, cardiac rehabilitation is an important part of recovery. Symptoms of depression and anxiety undermine recovery efforts, leaving recovering patients at risk for diminished functional capacity and heightened risk of mortality. Poor emotion regulation can worsen symptoms of depression and anxiety and hinder recovery efforts. OBJECTIVE: The purpose of this randomized controlled trial was to evaluate the early efficacy testing of a theoretically based emotion regulation treatment (Regulating Emotions to Improve Self-management of Nutrition, Exercise, and Stress [RENEwS]) designed to assist survivors of an acute cardiac event in cardiac rehabilitation to optimize recovery. METHODS: Survivors of an acute cardiac event in cardiac rehabilitation (n = 30, 83% men) were randomized to five 1-hour in-person group sessions of RENEwS or a phone-based attention-control group. Participants completed measures of depression and anxiety symptoms at 3 time points. Moderate to vigorous physical activity (MVPA) was objectively measured for 7 days at each time point using waist-worn actigraphy monitors. Between-group differences were calculated using analysis of variance with Cohen f effect sizes calculated to evaluate initial efficacy. RESULTS: There was no statistically significant difference in depression, anxiety, or MVPA over time based on group assignment (all P > .05). Compared with attention control participants, in RENEwS participants, preliminary effects showed greater reductions in depression (Cohen f = 0.34) and anxiety (Cohen f = 0.40) symptoms but only modest improvements in MVPA from baseline to 5 months (Cohen f = 0.08). CONCLUSIONS: Findings show that RENEwS is a promising emotion regulation intervention to enhance cardiac rehabilitation and potentially decrease symptoms of depression and anxiety.

RESUMO

BACKGROUND: The recently described optimized Oxford skeletal maturity system utilizes anteroposterior (AP) hip radiographs to accurately, rapidly, and reliably estimate skeletal maturity. However, in the real-world setting, significant positional variation in AP hip radiographs may influence the accuracy of optimized Oxford skeletal age estimates. We sought to evaluate the consistency of skeletal age estimations using the optimized Oxford system between differently rotated radiographs. METHODS: Thirty normal computerized tomography scans of males (15 children, 9 to 15 y) and females (15 children, 8 to 14 y) were obtained retrospectively, converted into 3D reconstructions, and then used to produce simulated hip radiographs in five different rotational positions. The optimized Oxford system was applied to the 150 simulated AP hip radiographs (5 differently rotated views of 30 hips) to produce a skeletal age estimate for each. RESULTS: Rotational position did not have a statistically significant effect on the skeletal age (P=0.84) using 1-way repeated measures analysis of variance. Of the 5 radiographic parameters in the optimized Oxford system, only greater trochanter height showed significant rotational variation after Greenhouse-Geisser correction (F2.58, 74.68=5.98, P<0.001). However, post hoc analyses showed that the greater trochanter height obtained at the most centered position was not different from the other 4 rotational positions (P>0.05 for all). CONCLUSION: The optimized Oxford skeletal maturity system is resilient to rotational variation. Mildly to moderately rotated radiographs obtained in the modern clinical setting can be used for skeletal age estimation by this method, broadening the clinical usage of this system. LEVEL OF EVIDENCE: Level III-diagnostic study.

RESUMO

BACKGROUND: Predicting ultimate lower extremity length is important in the treatment of lower limb length discrepancy (LLD), congenital limb deficiency, and other etiologies. Utilizing skeletal age over chronological age improves the prediction of ultimate lower extremity length. The recently described modified Fels knee skeletal maturity system allows for skeletal age estimation via imaging always available in LLD patients. We sought to compare the accuracy of the modified Fels knee skeletal maturity system versus chronological age in ultimate limb length prediction of a modern adolescent clinical population. METHODS: The medical records of all patients treated at our institution over a 20-year period with unilateral lower extremity pathology and available lower extremity imaging before and after reaching skeletal maturity were reviewed. Skeletal maturity was defined radiographically by closed distal femoral, proximal tibial, and proximal fibular physes. The femoral, tibial, and lower extremity length was measured in all radiographs. The modified Fels knee skeletal maturity system was applied to all radiographs obtained before maturity to estimate skeletal age. The accuracy of 3 widely utilized lower extremity length prediction systems was compared when utilizing estimated Fels skeletal age versus chronological age inputs. RESULTS: A total of 245 radiographs (109 before maturity) from 43 patients were eligible for inclusion. On cross-sectional analysis, linear modeling using Fels skeletal ages was uniformly associated with higher (improved) R2 values than chronological age-based models. On longitudinal analysis, skeletal age mixed-effects models had significantly lower (improved) Akaike information criterion and Bayesian information criterion values than chronological age models in all cases. Cohen d values were also significantly different (P<0.05) for the skeletal age models compared with chronological age models in all cases. CONCLUSIONS: In the treatment of LLD, the modified Fels knee skeletal maturity system can be readily applied to available imaging to improve the prediction of ultimate femoral, tibial, and lower extremity length. This skeletal maturity system may have significant utility in the estimation of ultimate LLD and determination of appropriate timing of epiphysiodesis. LEVEL OF EVIDENCE: Level III.

RESUMO

In this paper, we propose an innovative method for jointly analyzing survival data and longitudinally measured continuous and ordinal data. We use a random effects accelerated failure time model for survival outcomes, a linear mixed model for continuous longitudinal outcomes and a proportional odds mixed model for ordinal longitudinal outcomes, where these outcome processes are linked through a set of association parameters. A primary objective of this study is to examine the effects of association parameters on the estimators of joint models. The model parameters are estimated by the method of maximum likelihood. The finite-sample properties of the estimators are studied using Monte Carlo simulations. The empirical study suggests that the degree of association among the outcome processes influences the bias, efficiency, and coverage probability of the estimators. Our proposed joint model estimators are approximately unbiased and produce smaller mean squared errors as compared to the estimators obtained from separate models. This work is motivated by a large multicenter study, referred to as the Genetic and Inflammatory Markers of Sepsis (GenIMS) study. We apply our proposed method to the GenIMS data analysis.

RESUMO

BACKGROUND: Children with perinatally acquired human immunodeficiency virus (HIV; PHIVs) face a lifelong cumulative exposure to HIV and antiretroviral therapy (ART). The relationship between gut integrity, microbial translocation, and inflammation in PHIV is poorly understood. METHODS: This is a cross-sectional study in 57 PHIVs, 59 HIV-exposed but uninfected children, and 56 HIV-unexposed and -uninfected children aged 2-10 years old in Uganda. PHIVs were on stable ART with HIV-1 RNA <400 copies/mL. We measured markers of systemic inflammation, monocyte activation, and gut integrity. Kruskal-Wallis tests were used to compare markers by group and the Spearman correlation was used to assess correlations between biomarkers. RESULTS: The mean age of all participants was 7 years and 55% were girls. Among PHIVs, the mean CD4 % was 34%, 93% had a viral load ≤20 copies/mL, and 79% were on a nonnucleoside reverse transcriptase inhibitor regimen. Soluble cluster of differentiation 14 (sCD14), beta-D-glucan (BDG), and zonulin were higher in the PHIV group (P ≤ .01). Intestinal fatty acid binding protein (I-FABP) and lipopolysaccharide binding protein (LBP) did not differ between groups (P > .05). Among PHIVs who were breastfed, levels of sCD163 and interleukin 6 (IL6) were higher than levels in PHIV who were not breastfed (P < .05). Additionally, in PHIVs with a history of breastfeeding, sCD14, BDG, LBP, zonulin, and I-FABP correlated with several markers of systemic inflammation, including high-sensitivity C-reactive protein, IL6, d-dimer, and systemic tumor necrosis factor receptors I and II (P ≤ .05). CONCLUSIONS: Despite viral suppression, PHIVs have evidence of altered gut permeability and fungal translocation. Intestinal damage and the resultant bacterial and fungal translocations in PHIVs may play a role in the persistent inflammation that leads to many end-organ diseases in adults.Despite viral suppression, children with perinatally acquired human immunodeficiency virus (HIV) in Uganda have evidence of alterations in intestinal permeability and fungal translocation, compared to HIV-exposed but uninfected and HIV-unexposed children, which may play a role in HIV-associated chronic inflammation.

RESUMO

BACKGROUND: The risk of cardiovascular disease (CVD) and its mechanisms in children living with perinatally acquired HIV (PHIV) in sub-Saharan Africa has been understudied. METHODS: Mean common carotid artery intima-media thickness (IMT) and pulse-wave velocity (PWV) were evaluated in 101 PHIV and 96 HIV-negative (HIV-) children. PHIV were on ART, with HIV-1 RNA levels ≤400 copies/mL. We measured plasma and cellular markers of monocyte activation, T-cell activation, oxidized lipids, and gut integrity. RESULTS: Overall median (interquartile range, Q1-Q3) age was 13 (11-15) years and 52% were females. Groups were similar by age, sex, and BMI. Median ART duration was 10 (8-11) years. PHIV had higher waist-hip ratio, triglycerides, and insulin resistance (P ≤ .03). Median IMT was slightly thicker in PHIVs than HIV- children (1.05 vs 1.02 mm for mean IMT and 1.25 vs 1.21 mm for max IMT; P < .05), while PWV did not differ between groups (P = .06). In univariate analyses, lower BMI and oxidized LDL, and higher waist-hip ratio, hsCRP, and zonulin correlated with thicker IMT in PHIV (P ≤ .05). After adjustment for age, BMI, sex, CD4 cell count, triglycerides, and separately adding sCD163, sCD14, and hsCRP, higher levels of intestinal permeability as measured by zonulin remained associated with IMT (ß = 0.03 and 0.02, respectively; P ≤ .03). CONCLUSIONS: Our study shows that African PHIV have evidence of CVD risk and structural vascular changes despite viral suppression. Intestinal intestinal barrier dysfunction may be involved in the pathogenesis of subclinical vascular disease in this population.

RESUMO

Fatigue and depressive symptoms are prevalent and associated with poor clinical outcomes, though the underlying physiological mechanisms of fatigue and depression are poorly understood. We examined the impact of cardiorespiratory fitness (CRF) on fatigue and depressive symptoms in one-hundred and nine PLHIV. CRF was examined by maximal cardiorespiratory stress test and determined by peak oxygen uptake. Patient-reported fatigue was examined utilizing the HIV-Related Fatigue Scale. Depressive symptoms were examined with the Beck Depression Inventory and PROMISE 29. Data was collected at baseline and six months. Generalized estimating equations were used to determine the effect of CRF on fatigue and depressive symptoms over time. Participants were approximately 53 years old, 86% African American (n = 93), and 65% male (n = 70). After controlling for age and sex, fatigue was inversely associated with CRF (ß = -0.163; p = .005). Depressive symptoms were not associated with CRF as measured by the BeckDepression Inventory (p = .587) nor PROMIS 29 (p = .290), but over time, depressive symptoms decreased (p = .051). Increased CRF was associated with decreased fatigue levels, but was not associated with depressive symptoms. These results should guide future research aimed at how CRF might inform interventions to improve fatigue in PLHIV.

RESUMO

We aimed to evaluate differences in socio-economic variables in a Ugandan cohort of children with perinatally acquired HIV (PHIVs), HIV exposed uninfected (HEU) and HIV unexposed uninfected (HIV-) children and their associations with markers of inflammation and intestinal integrity. This is a cross-sectional study in 57 PHIV, 59 HEU and 56 HIV - children aged 2-10 years old enrolled in Uganda. Mean age of all participants was 7 years and 55% were girls. Compared to HEU and HIV - children, PHIVs were more likely to have parents that only completed a primary education, live in a household without electricity and live in poverty (p≤0.034). PHIVs living in poverty had higher IL-6 (p=0.006), those with lack of electricity had higher hsCRP, IL6, sTNFRII and d-dimer (p≤0.048) and PHIVs with an unprotected water source had higher IL6 and d-dimer (p≤0.016). After adjusting for demographic and HIV variables, IL-6 and d-dimer remained associated with lack of electricity and having an unprotected water source only in PHIVs (p<0.019). Our findings suggest that addressing economic insecurity may mitigate the persistent low-level inflammation in HIV that lead to many end organ disease. Longitudinal studies are needed to better understand the impact of socioeconomic factors on HIV inflammation and comorbidities.

RESUMO

BACKGROUND: Selenium, zinc, and chromium are essential micronutrients. Their alterations have been associated with HIV disease progression, metabolic complications, and mortality. METHODS: This is a cross-sectional study in children with perinatally acquired HIV (PHIV, n = 57), HIV-exposed uninfected (HEU, n = 59), and HIV-unexposed uninfected (HIV-, n = 56) children aged 2 to 10 years old, age- and sex-matched, enrolled in Uganda. PHIV were on stable antiretroviral therapy (ART) with undetectable viral load. We measured plasma concentrations of selenium, zinc, and chromium as well as markers of systemic inflammation, monocyte activation, and gut integrity. RESULTS: Among PHIV children, 93% had viral load ≤20 copies/mL, median CD4 was 37%, and 77% were receiving a nonnucleotide reserve transcriptase regimen. Median age of all participants was 8 years and 55% were girls. Median selenium concentrations were higher in PHIV compared with the HEU and HIV groups (P < 0.001), 46% of children overall had low zinc status (P = 0.18 between groups). Higher selenium, but not chromium or zinc, was associated with lower IL6, sTNFRI and II, and higher beta d glucan, a marker of fungal translocation, zonulin, a marker of gut permeability, oxidized LDL and insulin resistance (P ≤ 0.01). CONCLUSION: In this cohort of PHIV on ART in Uganda, there is a high prevalence of low zinc status overall. Higher plasma selenium concentrations were associated with lower systemic inflammation and higher gut integrity markers. Although our findings do not support the use of micronutrient supplementation broadly for PHIV in Uganda, further studies are warranted to assess the role of selenium supplements in attenuating heightened inflammation.

RESUMO

BACKGROUND: Racial discrimination is one of many barriers experienced by African Americans that interfere with health self-care management. Discrimination stress may decrease the tendency for individuals to resonate with the social-emotional appeals embedded in persuasive health information, which are known to play a key role in producing behavior change. Understanding the neurobehavioral underpinnings of discrimination stress experienced by African Americans may help reduce or resolve this important health disparity. OBJECTIVES: The purpose of this secondary analysis was to examine the association between neural processing of health information and perceived discrimination. In particular, we focused on three previously identified measures of health information processing associated with distinct brain areas: analytic network, empathy network, and the ventral medial prefrontal cortex. METHODS: Data were obtained from 24 African Americans enrolled in a blood pressure self-care management study. Participants completed surveys assessing racial discrimination and global stress, as well as a 40-minute functional magnetic resonance imaging protocol used to measure neural activation associated with processing different types of health information. RESULTS: Discrimination stress was significantly related to reduced activation of the empathy network and ventral medial prefrontal cortex, whereas there was a nonsignificant positive relationship with activity in the analytic network. DISCUSSION: Uncovering associations between patient experiences, such as racial discrimination, and their neural processing of health information can lead to the development of tailored health messages and self-care management interventions. This may inform strategies to close the gap on health outcomes.

RESUMO

BACKGROUND: Bronchopulmonary dysplasia (BPD) is a chronic lung disease and major pulmonary complication after premature birth. We have previously shown that increased intermittent hypoxemia (IH) events have been correlated to adverse outcomes and mortality in extremely premature infants. We hypothesize that early IH patterns are associated with the development of BPD. METHODS: IH frequency, duration, and nadirs were assessed using oxygen saturation (SpO2) waveforms in a retrospective cohort of 137 extremely premature newborns (<28 weeks gestation). Daily levels of inspired oxygen and mean airway pressure exposures were also recorded. RESULTS: Diagnosis of BPD at 36 weeks postmenstrual age was associated with increased daily IH, longer IH duration, and a higher IH nadir. Significant differences were detected through day 7 to day 26 of life. Infants who developed BPD had lower mean SpO2 despite their exposure to increased inspired oxygen and increased mean airway pressure. CONCLUSIONS: BPD was associated with more frequent, longer, and less severe IH events in addition to increased oxygen and pressure exposure within the first 26 days of life. Early IH patterns may contribute to the development of BPD or aid in identification of neonates at high risk.

RESUMO

Symptom distress remains a challenging aspect of living with HIV. Physical activity is a promising symptom management strategy, but its effect on symptom distress has not been examined in a large, longitudinal HIV-infected cohort. We hypothesized that higher physical activity intensity would be associated with reduced symptom distress. We included 5370 people living with HIV (PLHIV) who completed patient-reported assessments of symptom distress, physical activity, alcohol and substance use, and HIV medication adherence between 2005 and 2016. The most frequent and burdensome symptoms were fatigue (reported by 56%), insomnia (50%), pain (46%), sadness (45%), and anxiety (45%), with women experiencing more symptoms and more burdensome symptoms than men. After adjusting for age, sex, race, time, HIV medication adherence, alcohol and substance use, site, and HIV RNA, greater physical activity intensity was associated with lower symptom intensity. Although individual symptoms may be a barrier to physical activity (e.g. pain), the consistent association between symptoms with physical activity suggests that more intense physical activity could mitigate symptoms experienced by PLHIV.

RESUMO

OBJECTIVE: To compare the effectiveness of telephone-delivered interventions on fatigue, physical activity, and quality of life outcomes in adults with multiple sclerosis (MS). DESIGN: A single-blinded, randomized controlled trial. Participants were randomized to contact-control intervention (CC), physical activity-only intervention (PA-only), and physical activity plus fatigue self-management intervention (FM+). Outcomes were measured at baseline (2wk prerandomization), posttest (14wk postrandomization), and follow-up (26wk postrandomization). SETTING: Telephone-delivered in Midwest and Northeast regions of the United States. PARTICIPANTS: Inactive adults with MS (N=208) and moderate-to-severe fatigue. INTERVENTIONS: Three or 6 group teleconferences followed by 4 individually tailored phone calls delivered during 12 weeks. An occupational therapist and research assistant delivered the teleconferences and tailored phone calls, respectively. MAIN OUTCOME MEASURES: Primary outcomes were self-report fatigue and physical activity measured with the Fatigue Impact Scale and Godin Leisure-Time Exercise Questionnaire, respectively. Secondary outcomes included quality of life measured with the Multiple Sclerosis Impact Scale and moderate-to-vigorous exercise and step count measured with an accelerometer. RESULTS: Linear mixed effects models showed FM+ significantly improved self-reported fatigue (ß=-11.08; P=.03) and physical activity (ß=0.54; P=.01) compared with CC at posttest. However, FM+ had nonsignificant differences compared with PA-only on self-report fatigue (ß=-1.08, P=.84) and physical activity (ß=0.09; P=.68) at posttest. PA-only had significant improvements compared with CC on moderate-to-vigorous exercise (ß=0.38; P=.02) at posttest and step count at posttest (ß=1.30; P<.01) and follow-up (ß=1.31; P=.01) measured with an accelerometer. FM+ and PA-only had nonsignificant differences compared with CC on quality of life. CONCLUSIONS: Group teleconferences followed by tailored phone calls have a small yet statistically significant effect in promoting physical activity and reducing fatigue impact in people with MS.

RESUMO

BACKGROUND: Although many of the proposed mediating processes of self-management interventions are operationally defined as cognitive processes (e.g., acquiring and using information, self-efficacy, motivation, and decision-making), little is known about their underlying brain mechanisms. Brain biomarkers of how people process health information may be an important characteristic on which to individualize health information to optimize self-management of chronic conditions. OBJECTIVES: We describe a program of research addressing the identification of brain biomarkers that differentially predict responses to two types of health information (analytic focused and emotion focused) designed to support optimal self-management of chronic conditions. METHODS: We pooled data from two pilot studies (N = 52) that included functional magnetic resonance imaging during a specially designed, ecologically valid protocol to examine brain activation (task differentiation) associated with two large-scale neural networks-the Analytic Network and the Empathy Network-and the ventral medial prefrontal cortex while individuals responded to different types of health information (analytic and emotional). RESULTS: Findings indicate that analytic information and emotional information are processed differently in the brain, and the magnitude of this differentiation in response to type of information varies from person to person. Activation in the a priori regions identified in response to both analytic and emotion information was confirmed. The feasibility of obtaining brain imaging data from persons with chronic conditions also is demonstrated. DISCUSSION: An understanding of brain signatures related to information processing has potential to assist in the design of more individualized, effective self-management interventions.

RESUMO

This study examined the relationship of mothers' psychological well-being (depressive symptoms, posttraumatic stress symptoms) and resourcefulness with their technology-dependent infants' healthcare utilization (rehospitalization, emergency department [ED] visits) following discharge from the neonatal intensive care unit (NICU). This descriptive, correlational study was conducted at a large Midwest level 4 NICU in the United States. Mothers (n = 19) with a technology-dependent infant (eg, supplemental oxygen, feeding tubes) to be discharged home from the NICU within 2 to 3 weeks were interviewed face-to-face using standardized instruments. Infant rehospitalization and ED visit data were collected from the electronic medical record (EMR) for the first 3 months following the infant's discharge. Analyses included descriptive statistics and negative binomial regression. A majority of infants (72.2%) required at least 1 hospitalization; 33% required at least one ED visit. Mothers' age and resourcefulness were significant predictors of ED visits while only resourcefulness predicted rehospitalizations. Neither depressive symptoms nor posttraumatic stress symptoms significantly predicted healthcare utilization. Maternal resourcefulness was the only main variable that significantly predicted both ED visits and hospitalizations and one of the few modifiable factors that could assist mothers with successfully coping with the complexity of caring for a technology-dependent infant. Future research should focus on interventions to enhance mothers' resourcefulness prior to their technology-dependent infant's NICU discharge.

RESUMO

Mothers of infants in the neonatal intensive care unit (NICU) face stressors including turbulent emotions from their pregnancy/unexpected preterm delivery and their infant's unpredictable health status. The study purpose was to examine the psychological state of mothers prior to the discharge of their technology-dependent infants (eg, feeding tubes, supplemental oxygen) from the NICU to home. The study sample consisted of mothers (N = 19) of infants dependent on medical technology being discharged from a large Midwest NICU. A descriptive, correlational design using convenience sampling was employed to recruit mothers to examine associations of infant and maternal factors, resourcefulness, and stress with psychological state (depressive symptoms, posttraumatic stress symptoms). Forty-two percent of mothers were at high risk for clinical depression, with 37% in the clinical range for posttraumatic stress disorder. Increased maternal depressive symptoms were significantly associated with the increased frequency and perceived difficulty of their stress and posttraumatic stress symptoms. Increased posttraumatic stress symptoms were significantly associated solely with elevated depressive symptoms. This study identified factors associated with the mothers' increased psychological distress, providing beginning evidence for future interventions to employ prior to their technology-dependent infant's NICU discharge.
