Sleep, diurnal preference, health, and psychological well-being: a prospective single-allelic-variation study

Individual differences in sleep and diurnal preference associate with physical and mental health characteristics, but few genetic determinants of these differences have been identified. A variable number tandem repeat (VNTR) polymorphism in the PERIOD3 (PER3) gene (rs57875989) has been reported to associate with diurnal preference, i.e., preferred timing of waking and sleep. Here, the authors investigate in a prospective single-candidate genetic variant study whether allelic variation for this polymorphism associates also with reported actual sleep timing and sleep duration, as well as psychological and health measures. Six hundred and seventy-five subjects, aged 20 to 35 yrs, completed questionnaires to assess sleep and psychological and health characteristics and were genotyped for the PER3 VNTR. Homozygosity for the longer allele (PER3(5/5)) of the VNTR was associated with increased morning preference, earlier wake time and bedtime, and reduced daytime sleepiness. Separate analyses of work and rest days demonstrated that the increase in time in bed during rest days was greatest in PER3(5/5) homozygotes. PER3 genotype modified the effects of sleep timing and duration on fluid intelligence and body mass index. Genotype was not associated with physical or psychological characteristics as assessed by the SF-36 Health Questionnaire, the General Health Questionnaire, the Big Five Inventory, the Behavioral Inhibition System-Behavioral Activation System scales, and the Positive and Negative Affect Scale, even though these measures varied significantly with diurnal preference as assessed by the Morningness-Eveningness Questionnaire. Whereas diurnal preference also predicts mental health and psychological characteristics, as well as sleep timing, the PER3 VNTR specifically affects measures of sleep timing and may also modify the effects of sleep on health outcome measures.     

Health care experiences of people with dementia and their caregivers: a meta-ethnographic analysis of qualitative studies

Background:

Understanding the health care experience of people with dementia and their caregivers is becoming increasingly important given the growing number of affected individuals. We conducted a systematic review of qualitative studies that examined aspects of the health care experience of people with dementia and their caregivers to better understand ways to improve care for this population.

Methods:

We searched the electronic databases MEDLINE, Embase, PsychINFO and CINAHL to identify relevant articles. We extracted key study characteristics and methods from the included studies. We also extracted direct quotes from the primary studies, along with the interpretations provided by authors of the studies. We used meta-ethnography to synthesize the extracted information into an overall framework. We evaluated the quality of the primary studies using the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist.

Results:

In total, 46 studies met our inclusion criteria; these involved 1866 people with dementia and their caregivers. We identified 5 major themes: seeking a diagnosis; accessing supports and services; addressing information needs; disease management; and communication and attitudes of health care providers. We conceptualized the health care experience as progressing through phases of seeking understanding and information, identifying the problem, role transitions following diagnosis and living with change.

Interpretation:

The health care experience of people with dementia and their caregivers is a complex and dynamic process, which could be improved for many people. Understanding these experiences provides insight into potential gaps in existing health services. Modifying existing services or implementing new models of care to address these gaps may lead to improved outcomes for people with dementia and their caregivers.The global prevalence of Alzheimer disease and related dementias is estimated to be 36 million people and is expected to double in the next 20 years.¹ Several recent strategies for providing care to patients with dementia have highlighted the importance of coordinated health care services for this growing population.^2–5 Gaps in the quality of care for people with dementia have been identified,^6–8 and improving their quality of care and health care experience has been identified as a priority area.^2–5Incorporating the health care experience of patients and caregivers in health service planning is important to ensure that their needs are met and that person-centred care is provided.⁹ The health care experience of people with dementia and their caregivers provides valuable information about preferences for services and service delivery.¹⁰ Matching available services to patient treatment preferences leads to improved patient outcomes^11,12 and satisfaction without increasing costs.¹³ Qualitative research is ideally suited to exploring the experiences and perspectives of patients and caregivers and has been used to examine these experiences for other conditions.¹⁴ We performed a systematic review and meta-ethnographic synthesis of qualitative studies exploring the health care experience of people with dementia and their caregivers in primary care settings, and we propose a conceptual framework for understanding and improving these health care experiences.     

A cross-cultural study of adolescents--BMI, body image and psychological well-being

Physical, psychological and social changes that occur during adolescence can markedly affect dietary habits and nutritional health. Physical changes including rapid growth place extra nutritional requirements on adolescents, while culture and society require adjustments in all of the aspects of daily living, including psychosocial well-being. Adolescents become focused on the physical appearance and any deviation from the ideal figure can result in negative dieting behavior, social withdrawal, poor self-esteem and increased health vulnerability. The paper presents some of the results of an international comparative study on risk and protective factors of adolescent health and well being, related to BMI, dieting behavior and body image and their relationship to psychosocial well-being (somatic stress, anxiety, depression, life satisfaction and self-esteem). Within an ecological cultural framework, it looks at group-specific differences of Albanian and Bosnian adolescents within different socio-cultural contexts across six European countries: two EU members (Italy and Austria) and four communities in the state of socioeconomic and political transition (Croatia, Bosnia and Herzegovina, Albania and Kosovo). The survey collected data from 2000 adolescents between 15 and 18 years of age. The study demonstrated a strong relationship between BMI and body dissatisfaction, between body image and dietary habits, and strong effects of body image on all indicators of psychosocial health. In addition to expected marked gender differences in all countries, the obtained results indicate significant intracultural variations related to socioeconomic status as well as considerable intercultural variations due to variable influence specific social and cultural contexts.     

Performance in daily activities,cognitive impairment and perception in multiple sclerosis patients and their caregivers

Background

The relationship between cognitive assessment results in multiple sclerosis (MS) and performance in daily activities (DAs) remains unclear. Our study aimed to evaluate the relationship between cognitive functions (CF) measured by tests, performance in DAs, and the perception of CF in patients and their caregivers (CG) in MS.

Methods

The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) battery was used to evaluate cognitive status. We created an ad hoc questionnaire (DaQ) to assess performance in DAs not requiring specific motor skills. We used the Multiple Sclerosis Neuropsychological Questionnaire (MSNQ) to measure each patient self-judgment and caregiver’s perception of CF.

Results

Forty-nine patients and their caregivers were included in the study. Significant correlations were found between the BICAMS and the DaQ (Symbol Digit Modalities Test (SDMT): r?=???0.48, p?<?0.001; California Verbal Learning Test (CVLT): r?=???0.33, p?=?0.01; Brief Visual Memory Test (BVMT-R): r?=???0.42; p?=?0.002); patients self-judgment (SDMT: r?=???0.38, p?=?0.004; CVLT: r?=???0.26, p?=?0.03); caregiver perception of patient’s CF (SDMT: r?=???0.52, p?<?0.001; CVLT: r?=???0.3, p?=?0.01; BVMT-R: r?=???0.42, p?=?0.002). The difference in perception between the patients and their caregivers was related to patient age (p?=?0.001) and severity of cognitive impairment (p?=?0.03).

Conclusions

Cognitive assessment results show a significant correlation with performance in daily activities and with patients and, especially, caregiver perception of cognitive impairment. These data support the importance of a routine evaluation of cognitive function in MS that includes an anamnestic evaluation of patients, and, when possible, consideration of the caregiver’s point of view.

     

What worries parents when their preschool children are acutely ill,and why: a qualitative study.

OBJECTIVE: To identify and explore parents'' concerns when young children become acutely ill. DESIGN: Qualitative study making use of semi-structured one to one and group interviews with parents of preschool children. SETTING: Disadvantaged inner city community. SUBJECTS: 95 parents of preschool children. RESULTS: Fever, cough, and the possibility of meningitis were parents'' primary concerns when their children became acutely ill. Parents'' concerns reflected lay beliefs, their interpretation of medical knowledge, and their fears that their child might die or be permanently harmed. Parents worried about failing to recognise a serious problem. Concerns were expressed within the context of keenly felt pressure, emphasising parents'' responsibility to protect their child from harm. They were grounded in two linked factors: parents'' sense of personal control when faced with illness in their child and the perceived threat posed by an illness. CONCLUSIONS: Better understanding of parents'' concerns may promote effective communication between health professionals and parents. Modification of parents'' personal control and perceived threat using appropriate information and education that acknowledge and address their concerns may be a means of empowering parents.     

Neuropathic pain and psychological morbidity in patients with treated leprosy: a cross-sectional prevalence study in Mumbai

Background

Neuropathic pain has been little studied in leprosy. We assessed the prevalence and clinical characteristics of neuropathic pain and the validity of the Douleur Neuropathique 4 questionnaire as a screening tool for neuropathic pain in patients with treated leprosy. The association of neuropathic pain with psychological morbidity was also evaluated.

Methodology/Principal Findings

Adult patients who had completed multi-drug therapy for leprosy were recruited from several Bombay Leprosy Project clinics. Clinical neurological examination, assessment of leprosy affected skin and nerves and pain evaluation were performed for all patients. Patients completed the Douleur Neuropathique 4 and the 12-item General Health Questionnaire to identify neuropathic pain and psychological morbidity.

Conclusions/Significance

One hundred and one patients were recruited, and 22 (21.8%) had neuropathic pain. The main sensory symptoms were numbness (86.4%), tingling (68.2%), hypoesthesia to touch (81.2%) and pinprick (72.7%). Neuropathic pain was associated with nerve enlargement and tenderness, painful skin lesions and with psychological morbidity. The Douleur Neuropathique 4 had a sensitivity of 100% and specificity of 92% in diagnosing neuropathic pain. The Douleur Neuropathique 4 is a simple tool for the screening of neuropathic pain in leprosy patients. Psychological morbidity was detected in 15% of the patients and 41% of the patients with neuropathic pain had psychological morbidity.     

General health, psychological well-being and distress of youth immigrants in Italy

In seeking to ease the rehabilitation of refugees there has generally been a failure to take account of the complexity of the refugees' experience of suffering and loss. In this their psychological and emotional well-being as well as the social and economic aspects of the question have frequently been of only peripheral concern, and the response to the psychological impact of violence has been primarily focused on the concept of Post-Traumatic Stress Disorder (PTSD). This approach assumes a pathological response to stress that is both universal across different cultures and centred on the potential of pathologizing coping strategies that might be essential not only for survival but also for psychological well-being.     

Patients' experiences with partial dentures: a qualitative study

Objective: The aim of the study was to gain insight into people's experiences of being given and using partial dentures. Methods: In‐depth semi‐structured interviews were carried out with 23 people of varied age, social background and denture wearing experience in Tayside, Scotland. Participants were encouraged to discuss how they came to have partial dentures, their day‐to‐day denture use and their interactions with dentists. The interview data were systematically coded using key theme headings, and summary charts were constructed to facilitate analysis. Results: The initial decision that a partial denture was needed was generally difficult to accept. People perceived the main benefits of partial dentures to be improved appearance and confidence, but experienced a variety of difficulties with their dentures and often coped with these by only wearing them on social occasions. Participants had not always told their dentists about the difficulties they experienced. Barriers to seeking help with denture problems included financial constraints, previous experience of rushed appointments or poor communication from dentists and a perceived lack of entitlement to help when partial dentures were issued free. Conclusions: Partial dentures can be difficult to cope with. People experience a range of difficulties in wearing them, not all of which have been discussed with dentists. Informative and supportive communication when partial dentures are first needed, and subsequently, can improve the quality of patients’ experiences and may help promote effective use and appropriate help‐seeking by partial denture wearers.     

Mixed emotional experience is associated with and precedes improvements in psychological well-being

Background

The relationships between positive and negative emotional experience and physical and psychological well-being have been well-documented. The present study examines the prospective positive relationship between concurrent positive and negative emotional experience and psychological well-being in the context of psychotherapy.

Methods

47 adults undergoing psychotherapy completed measures of psychological well-being and wrote private narratives that were coded by trained raters for emotional content.

Results

The specific concurrent experience of happiness and sadness was associated with improvements in psychological well-being above and beyond the impact of the passage of time, personality traits, or the independent effects of happiness and sadness. Changes in mixed emotional experience preceded improvements in well-being.

Conclusions

Experiencing happiness alongside sadness in psychotherapy may be a harbinger of improvement in psychological well-being.     

A head above the rest: Height and adolescent psychological well-being

Using data from the National Longitudinal Study of Adolescent Health, we examine the effect of adolescent height on mental health as measured by Center for Epidemiological Studies Depression (CES-D) scores and Rosenberg Self-Esteem (RSE) scores. We find evidence that height is associated with fewer symptoms of depression among females 17–19 years of age, and among males 12–19 years of age. The negative relationship between height and depression among males persists after controlling for body mass index (BMI), differences in pubertal timing, and individual fixed effects, but does not explain the effect of height on educational attainment. We conclude that there is a small psychological benefit for males to being taller as an adolescent.     

Psychosocial group intervention to enhance self-management skills of people with dementia and their caregivers: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: After diagnosis of a dementing illness patients and their spouses have many concerns related to the disease and their future. This often leads to poor psychological well-being and reduced health related quality of life (HRQoL) of the family. Support for self-management skills has been proven to be an effective method to improve prognosis of asthma, heart failure and osteoarthritis. However, self-management interventions have not been studied in dementia. Therefore, our aim was to examine in an objective-oriented group intervention the efficacy of self-management support program (SMP) on the HRQoL of dementia patients and their spousal caregivers as well as on the sense of competence and psychological well-being of care-givers. METHODS: During the years 2011-12, 160 dementia patients and their spouses will be recruited from memory clinics and randomized into two arms: 80 patients for group-based SMP sessions including topics selected by the participants, 80 patients will serve as controls in for usual community care. Sessions may include topics on dementia, community services, active lifestyle and prevention for cognitive decline, spousal relationship, future planning and emotional well-being. The patients and spouses will have their separate group sessions (10 participants/group) once a week for 8 weeks. Main outcome measures will be patients' HRQoL (15D) and spousal caregivers' HRQoL (RAND-36), and sense of competence (SCQ). Secondary measures will be caregivers' psychological well-being (GHQ-12) and coping resources, patients' depression, cognition and signs of frailty. Data concerning admissions to institutional care and the use and costs of health and social services will be collected during a two year follow-up. DISCUSSION: This is a "proof -of-concept" study to explore the efficacy of group support for self-management skills among dementia families. It will also provide data on cost-effectiveness of the intervention.     

Hymenopteran wing kinematics: a qualitative study

(With 9 plates and 2 figures in the text)
Wing deformations were studied in representatives of several hymenopteran families during free Right in hovering or near hovering conditions. The claval furrow, costal break, stigma and a variety of flexion lines occupying the wing apex are all involved in regulating forewing profile during the flight cycle in lchneumonidae and Tenthredinidae. In these families, as well as in the sphecid Sphex rujocincius , the median flexion line of the hindwing is also active in the terminal stages of supination. The plaiting fold of the vespid forewing plays an important role in profile control during the upstroke, reversing its polarity compared to rest. Little wing distortion was observed in the large scolids Scotia flavifrons and S. hirta , possibly attributable to the presence of strengthening ridges and grooves in the wing apex.     

Respecting the autonomy of cancer patients when talking with their families: qualitative analysis of semistructured interviews with patients.

OBJECTIVE: To discover cancer patients'' views about disclosure of information to their family, their family''s influence over the information given them, and their preferences for doctors'' behaviour if they and their family disagree, as a complement to applied ethical theory. DESIGN: Semistructured interviews followed by qualitative content analysis. SETTING: Mainly urban British general practice. SUBJECTS: 30 patients in whom cancer, excluding basal and squamous cell skin carcinomas, was diagnosed 1-7 years earlier. RESULTS: All subjects wished doctors to respect their views rather than those of their family, should they differ. With their consent, subjects favoured close family receiving information about their illness, all but one mentioning advantage to their family. Without such consent, six unconditionally favoured disclosure of information to their family while seven unconditionally opposed disclosure. Seventeen participants restricted their approval for such disclosure to specific circumstances. Only two participants approved of their family influencing the information that they received about their illness; all but seven wished to receive full information, the exceptions relating to information about bad prognosis. CONCLUSIONS: Subjects favoured openness with their family but most rejected unconditional disclosure of information without their consent and their family influencing what information they would be given. They valued respect for their autonomy more highly than beneficence and considered that their own needs took priority over those of their family.
