The present study examined longitudinal associations of distinct dimensions of perceived control (i.e., perceived mastery and constraints) with approach and avoidance coping relating to functional health for aging adults, which had not been well studied previously. Using data from two waves of Midlife in the United States (N = 4,963, whose mean age was 55.4 [ SD = 12.5]), a longitudinal path model was analyzed for direct and indirect effects among perceived mastery and constraints, approach and avoidance coping, and functional limitations. Bidirectional associations were observed between perceived mastery and approach coping and between perceived constraints and avoidance coping. Moreover, perceived constraints not only were directly associated with functional limitations but also mediated the longitudinal associations of the other factors of interest with functional limitations. These findings can inform future research on perceived control and coping in the context of promoting functional health. [ABSTRACT FROM AUTHOR]

Objectives While personal growth has been found to be associated with multiple aspects of health in adulthood, its associations with cognitive functioning have not been fully understood. The present study aimed to assess both directions of such longitudinal associations. Method Using data from the second wave (Time 1 [T1]) and third wave (Time 2 [T2]) of the Midlife in the United States (MIDUS) study (N = 4,206; mean age = 56.0 [standard deviation (SD) = 12.3]), a longitudinal measurement model containing latent variables of episodic memory and executive function was first constructed. Built on the measurement model, a cross-lagged panel model was analyzed to assess relationships between personal growth and the two areas of cognitive functioning, in which T1 personal growth predicted residualized changes in episodic memory and executive function, and T1 episodic memory and executive function predicted change in personal growth, controlling for covariates. Results T1 personal growth significantly predicted smaller decreases in episodic memory, whereas it did not predict change in executive function. T1 episodic memory, but not T1 executive function, significantly predicted smaller decreases in personal growth. Discussion The present findings were unique, particularly implying potential longitudinal reciprocity between personal growth and episodic memory. These findings and implications can inform future research aimed at exploring approaches to promoting personal growth and cognitive functioning among aging adults. [ABSTRACT FROM AUTHOR]

The longitudinal associations of primary and secondary control with two distinct aspects of happiness including hedonic/subjective and eudaimonic/psychological well-being had not been fully studied. The present study aimed to contribute to the literature by examining these associations and their age differences. Using data from the second and third waves of the Midlife in the United States (MIDUS; N = 4963, aged 28 to 84 at baseline), the present study conducted structural equation modeling analyses to examine whether one primary control strategy (persistence in goal striving) and two secondary control strategies (positive reappraisals and lowering aspirations) predicted residualized changes in the latent constructs of subjective well-being (SWB) and psychological well-being (PWB) and whether there were age differences in these associations. The results indicate that persistence in goal striving and lowering aspirations overall predicted changes in PWB while none of the control strategies did for SWB, but some age differences were found. Whereas these differences somewhat varied for the outcomes of SWB and PWB, the findings indicate tendencies for older individuals compared to younger individuals of more negative (or less positive) associations of persistence in goal striving and more positive (or less negative) and more negative associations of positive reappraisals and lowering aspirations, respectively, with these outcomes. The present study suggested potential directions of future research aimed at further examining the role of primary and secondary control for happiness and exploring potential interventions to promote happiness, for example, by modifying primary and/or secondary control for adults of different ages.

Social integration has documented benefits for late-life health; yet, little is known about its impacts on trajectories of physical functioning. This study examines age and gender differences in the longitudinal associations between social integration and activities of daily living (ADLs) using a hierarchical linear model with three waves of survey data collected over 4 years from the Social Integration and Aging Study (N = 400; baseline mean age = 80.3). Findings indicated some interaction effects of age, gender, and/or social integration on ADL trajectories. Among those of more advanced age, women showed greater increases in ADL limitations than men, and individuals with lower social integration experienced greater increases in ADL limitations than those with higher social integration. Neither of these patterns were found among younger older adults. This study highlights the benefits of longitudinal research on social integration and the need to explore practical interventions for promoting social integration particularly among the oldest older adults.

It has not been well understood how conscientiousness and neuroticism are associated with two related but distinct dimensions of perceived control (i.e., perceived mastery and constraints) among aging adults. The present study examined these associations and their change over time, while addressing whether they differ by age or gender. For respondents aged 50+ at baseline (N = 2,768) in the Midlife in the United States (MIDUS) study, multilevel modeling analyses were conducted to assess how conscientiousness and neuroticism predicted perceived mastery and constraints over 2 decades. As expected, higher conscientiousness and lower neuroticism (for both between- and within-person variability) predicted higher perceived mastery and lower perceived constraints overall. Nuanced findings emerged related to age, gender and change over time for different associations of conscientiousness and neuroticism with the outcomes. These findings can inform future research suggesting directions of further investigations for these complex associations. [ABSTRACT FROM AUTHOR]

Background and Objectives Research suggests longitudinal and reciprocal relationships between perceived control over life circumstances and health for Western populations; yet, such associations have not been fully understood for non-Western populations. The present study addresses cultural differences in these associations for American and Japanese aging adults. Research Design and Methods For respondents aged 40 and older at 2 waves (Time 1 [T1] and Time 2 [T2]) of Midlife in the United States (N = 4,455) and Midlife in Japan (N = 827), cross-lagged path models were analyzed for T1 perceived control predicting change in each health measure (i.e. self-rated health, number of chronic health conditions, and functional limitations) from T1 to T2; and the matched T1 health measure predicting change in perceived control from T1 and T2. In these analyses, the effects of T1 age, T1 perceived control, and each T1 health measure were compared cross-nationally. Results A cross-national difference emerged in that T1 perceived control predicted change in chronic health conditions only for Americans. Similar tendencies were found between the 2 nationalities for T1 perceived control predicting changes in self-rated health and functional limitations. Reciprocal relationships between perceived control and health measures were found for Americans, but neither age nor any of the T1 health measures predicted change in perceived control for the Japanese respondents. Discussion and Implications The findings suggest cultural differences and similarities between the 2 nationalities, which have implications for potential health benefits of enhancing perceived control among American and Japanese aging adults. Building on these findings, the present study also indicates future directions of research. [ABSTRACT FROM AUTHOR]

Stress can negatively affect multiple aspects of health, including functional health, among older adults, who are likely to face unique, age-related stressful experiences. Previous research has addressed the protective effects of social relations (i.e., social ties, social participation, and social integration) for physical and mental health outcomes, yet few studies have examined functional health. This study aimed to investigate the longitudinal stress-buffering effects of social integration on late-life functional health. Using three-wave data from 399 older adults (aged older than 60 years), two-level hierarchical linear modeling analysis was conducted and the results indicated that in addition to its main effect on functional (activity of daily living) limitations, social integration moderated the negative effect of stress on the longitudinal trajectory of functional limitations. The findings suggest important directions of future research to identify the mechanisms of such buffering effects over time and develop effective interventions to enhance late-life functional health while promoting social integration.

Personal growth is essential in the lives of adults of any age and is associated with a variety of well-being outcomes. Building on previous research on psychosocial factors associated with personal growth, the present study aimed to investigate whether and how psychosocial factors (including working, generativity, positive interpersonal relationships, and spirituality) could affect aging adults' personal growth longitudinally. Using three waves of Midlife in the United States data from adults with baseline ages of 20–75, two-level hierarchical linear modeling analyses were conducted to examine the effects of psychosocial factors as well as age and gender on levels and trajectories of personal growth over the span of nearly two decades. All the factors predicted levels of personal growth while positive relationships and generativity had larger effects relative to the others. In addition, some of the effects were moderated by baseline age or passage of time (i.e., aging). Particularly, the moderated effects involving positive relations were multifaceted. Among those with less positive relationships, older people's levels of personal growth remained lower than younger people over time. However, among those with more positive relationships, older people reported lower growth initially but the age difference was no longer confirmed two decades later. In other words, having positive relationships appeared to become increasingly important for aging adults to maintain higher personal growth. These findings suggest shifts in life priorities that could influence personal growth among aging adults, and the implications can be informative for future research and practice.

The present study examined a potential mechanism underlying college students’ resisting in-class media multitasking under contextual control from a behavioural economic perspective. Using a hierarchical cluster analysis, we first identified subgroups of students who differed in frequencies of media multitasking across two contexts (preferred and non-preferred classes). We then compared a subgroup of students who could resist media multitasking in one context but not in another context with other subgroups of students in terms of rates of delay discounting and levels of impulse control. In the delay-discounting task, participants made a series of choices between smaller amounts of hypothetical monetary rewards available immediately and a larger amount of hypothetical monetary rewards available after a delay. Impulse control was measured by a self-reported scale. The primary finding was that the subgroup of students who could resist media multitasking in preferred but not non-preferred classes showed significantly lower rates of delay discounting than the subgroup of students who frequently engaged in media multitasking in both preferred and non-preferred classes. Implications for developing effective intervention strategies from a behavioural economic perspective are discussed. [ABSTRACT FROM AUTHOR]

Abstract: Aims: Although morning hypertension (HT) has been identified as a major cardiovascular risk, susceptible populations remain unknown. This study aimed to clarify the relationship between morning HT and diabetes or obesity in a large-scale population. Main methods: Clinic blood pressure (BP) and BP upon awakening were recorded in 2554 outpatients with HT who attended 101 clinics or hospitals for two weeks. Mean clinic and awakening BP>140/90 and >135/85mmHg, respectively, were considered as HT. The patients were classified according to values for clinic and home BP, into normal BP, white coat HT, masked HT, and sustained HT. Key findings: Morning BP (mmHg) significantly and progressively elevated in the order of normal glucose tolerance, impaired glucose tolerance and diabetes (134.1±12.2, 135.4±13.1 and 137.5±11.5; p<0.0001). The incidence of morning HT significantly increased and progressively in the same order (53.4%, 55.6%, 66.4%, p<0.0001). Morning BP was significantly higher among obese patients with diabetes than among non-obese and non-diabetic patients (138.8±10.5, 133.1±11.9, p<0.0001). In addition, the incidence of morning HT was significantly higher in obese diabetic patients than in non-obese and non-diabetic patients (73.0% vs. 49.9%, p<0.0001). Significance: Diabetic or obese patients frequently have morning HT. [Copyright &y& Elsevier]

The article presents a study on the diets of the Elegant Scops-owl (Otus elegans) and the Japanese Scops-Owl (O. semitorques) found in a forest on Okinawa Island, Japan. The study evaluated their food niches and mechanisms that might differentiate their food niches. It was found that prey size and habitat differentiated their food niches. Elegant Scops-Owls' diets consist of small prey while Japanese Scops-Owls foraged on small to large-sized prey. The differences may be attributed to prey locomotion and body size differences between the two species.

Abandonment of sexual reproduction is a well-known characteristic in aquatic plants, while the causes, levels, and consequences of sterility are often unknown. Utricularia australis f. australis (Lentibulariaceae) is a free-floating, sterile bladderwort distributed widely in temperate and tropical regions. Experimental crosses in cultivated conditions, AFLP analysis, and cpDNA haplotypes of natural populations clearly demonstrated that U, australis f. australis originates from the asymmetric hybridization between two parental taxa: U. australis f. tenuicaulis (mostly as female) and U. macrorhiza (mostly as male). No post F1 hybrids were detected using the additive patterns of AFLP bands combined with the observation of extensive sterility in U. australis f. australis. Recurrent hybridizations and subsequent perpetuation by asexual reproduction were demonstrated by the unique, but monomorphic, AFLP genotypes observed in each U. australis f. australis population. Hybrids and parental species did not coexist, implying the superiority of the hybrid U. australis f. australis in certain environmental conditions. It remains unclear whether populations of U. australis f. australis are maintained by colonizing propagules or as relicts of past hybridization events. [ABSTRACT FROM AUTHOR]

Effects of moisture absorption on permittivity and surface roughness of lanthanum oxide (La2O3) films were investigated. It was found that the moisture absorption deteriorates the permittivity (k) of La2O3 films on silicon because of the formation of hexagonal La(OH)3 with a low permittivity after films were exposed to the air. Therefore, the moisture absorption should be a very possible reason for the permittivity variation of La2O3 film in literatures reported, so far. Furthermore, a roughness enhancement was also observed after La2O3 films were exposed to the air for several hours. This observation should be another concern of hygroscopic La2O3 film application.

Background: Most surgeons agree that symptomatic mediastinal bronchogenic cysts should be resected, and complete resection is considered mandatory to avoid recurrence. However, a symptomatic mediastinal bronchogenic cyst sometimes adheres to a vital organ, making complete resection hazardous. In such case, surgical resection using cardiopulmonary bypass should be performed to achieve complete resection. Case presentation: A 65-year-old female patient had undergone surgical drainage of a mediastinal bronchogenic cyst 30 years ago. Recently, she presented with complaints of orthopnea, and computed tomography revealed a few days later a subcarinal bronchogenic cyst markedly compressing the left atrium. Complete resection of the mediastinal bronchogenic cyst was performed using cardiopulmonary bypass. The postoperative course was uneventful. The patient was followed up for 1 year, with no recurrence of the bronchogenic cyst. Conclusions: For patients with mediastinal bronchogenic cysts compressing the left atrium, we recommend complete resection using cardiopulmonary bypass. [ABSTRACT FROM AUTHOR]

Introduction: Routine spinal fusion techniques have involved removal of all soft tissues and articular facets, decortication of all posterior elements, and application of bone graft to the fusion area. Bone grafting has been performed mainly using the patient's own bone (autograft bone), most commonly from the iliac crest. The use of autograft bone is accompanied by complications or problems because of harvesting and donor-site morbidity. Several studies have already reported the use of allograft bone in scoliosis surgery. However, these studies are small series with short-term follow-up. Method: Twenty-two patients with scoliosis who underwent posterior spinal fusion and pedicle-screw-alone fixation using banked allograft bone obtained from the regional bone bank in Japan were analyzed. The average age at surgery was 13 years 5 months. The average follow-up was 2 years 7 months, and the average age at the last follow-up was 15 years 6 months. Scoliosis curves were divided into two groups (single curve group and double curve group). Results: For the single curve group, the average preoperative coronal curve measured 78° (48°-85°) and the postoperative curve measured 22° (8°-35°), with no loss of correction at the last follow-up. For the double curve group, the average preoperative thoracic curve measured 64° (48°-85°) and the lumbar curve measured 42° (38°-60°). The average postoperative thoracic curve measured 12° (8°-34°) and lumbar curve measured 15° (8°-32°), with no significant loss of correction at the last follow-up. No patients had clinical complaints in the region of surgery at 9 months after surgery and thereafter. There were no complications including loss of correction, nonunion, infection and instrumentation failure. At the last follow-up, patients/parents were interviewed and asked to complete an outcome satisfaction questionnaire. They were asked to rate the outcome as very satisfactory, satisfactory, neither satisfactory nor unsatisfactory, unsatisfactory, or very unsatisfactory. Seventeen patients (77%) were very satisfied, four patients (17%) were satisfied, and one patient (6%) was neither satisfied nor unsatisfied. Autograft bone and banked allograft bone appear to yield comparable results and clinical outcomes. Conclusion: However, in Japan, various expenses accrue to supply a safe and premium quality of banked allograft bone. Financial issue must be resolved as soon as possible. [ABSTRACT FROM AUTHOR]

Instrumentation and fusion to the sacrum/pelvis has been a mainstay in the surgical treatment of scoliosis in patients with Duchenne muscular dystrophy since the development of the intrailiac post. It is recommended for correcting pelvic obliquity. However, caudal extent of instrumentation and fusion has remained a matter of considerable debate. This study was performed to determine the efficacy and safety of stopping segmental pedicle screw constructs at L5 during surgical treatment of scoliosis associated with Duchenne muscular dystrophy (DMD). From May 2005 to June 2007, a total of 20 consecutive patients underwent posterior spinal fusion and segmental pedicle screw instrumentation only to L5 for scoliosis secondary to DMD. All patients had progressive scoliosis, difficulty sitting, and back pain before surgery. A minimum 2-year follow-up was required for inclusion in this study. Assessment was performed clinically and with radiological measurements. The Cobb angles of the curves and spinal pelvic obliquity were measured on the coronal plane. Thoracic kyphosis and lumbar lordosis were measured on the sagittal plane. These radiographic assessments were performed before surgery, immediately after surgery, and at a 3-month interval thereafter. The operating time, blood loss, and complications were evaluated. Patients were questioned about whether they had difficulty sitting and felt back pain before surgery and at 6 weeks, 1 year, and 2 years after surgery. A total of 20 patients, aged 11–17 years, were enrolled. The average follow-up period was 37 months. Preoperative coronal curves averaged 70° (range 51°–85°), with a postoperative mean of 15° (range 8°–25°) and a mean of 17° (range 9°–27°) at the last follow-up. Pelvic obliquity improved from 13° (range 7°–15°) preoperatively to 5° degrees (range 3°–8°) postoperatively and 6° (range 3°–9°) at the last follow-up. Good sagittal plane alignment was recreated and maintained. Only a small loss of correction of scoliosis and pelvic obliquity was noted. The mean operating time was 271 min (range 232–308 min). The mean intraoperative blood loss was 890 ml (range 660–1260 ml). The mean total blood loss was 2100 ml (range 1250–2880 ml). There was no major complication. All patients reported that difficulty sitting and back pain were alleviated after surgery. Segmental pedicle screw instrumentation and fusion only to L5 is safe and effective in patients with DMD scoliosis of <85° and pelvic obliquity of <15°. Good sagittal plane alignment was achieved and maintained. All patients benefited from surgery in terms of improved quality of life. There was no major complication. [ABSTRACT FROM AUTHOR]

Background: The definition of electrical storm is still debated. For example, an electrical storm is defined as a clustering of three or more separate episodes of ventricular tachycardia/ventricular fibrillation within 24 hours or one or more episodes occurring within 5 minutes of termination of the previous episode of ventricular tachycardia/ventricular fibrillation. When it is refractory to medications, prompt assessments by coronary angiography, sedation, and overdrive pacing should be performed. An electrical storm may occur anytime, including at night or after the patient leaves an intensive care unit.Case Presentation: A 70-year-old Japanese man with type 2 diabetes mellitus was diagnosed as having ST-elevation myocardial infarction. His clinical course after an urgent percutaneous coronary intervention was uneventful, but he developed electrical storm that was refractory to antiarrhythmic medications on day 11 of hospitalization. We used sedative medications and performed ventricular overdrive pacing and transferred him to a university hospital for further treatment, which included electrical ablation and cardioverter-defibrillator implantation.Conclusion: An electrical storm is a relatively rare and fatal complication of acute myocardial infarction. It is important that the treatment choices for this condition are known by non-cardiologist physicians who might encounter this rare condition. [ABSTRACT FROM AUTHOR]
