Is fit it? the relationship between church/synagogue member fit and the psychosocial competence of the member

The relationship between the fit of the church/synagogue member with his/her congregation and the psychosocial competence of the member was studied. The religious leader from each of 12 congregations (four Jewish, four Protestant, and four Roman Catholic) nominated approximately six members who fit well within the congregation (central members) and six members who fit less well (peripheral members) according to a set of guidelines. One hundred thirty-three (133) congregation members, 77 central and 56 peripheral, participated. Central and peripheral members displayed significantly different psychosocial competence characteristics. However, neither central nor peripheral members manifested uniformly greater effectiveness across all of the competence scales. Specifically, central members indicated greater satisfaction with their congregation, a greater sense of control by God, and a lower level of efficacy, coping skills, and sense of control by chance. The findings suggest to change agents that the process of helping an individual fit within a system may be associated with negative as well as positive consequences for his/her effective functioning. This view conflicts with the notion that fit corresponds to psychological well-being, and points to the importance of studying the relationship between fit and multidimensional criteria of psychosocial competence across a variety of settings.     

Finding cancer stem cells: are aldehyde dehydrogenases fit for purpose?

Despite many years of intensive effort, there is surprisingly little consensus on the most suitable markers with which to locate and isolate stem cells from adult tissues. By comparison, the study of cancer stem cells is still in its infancy; so, unsurprisingly, there is great uncertainty as to the identity of these cells. Stem cell markers can be broadly categorized into molecular determinants of self‐renewal, clonogenicity, multipotentiality, adherence to the niche, and longevity. This review assesses the utility of recognizing cancer stem cells by virtue of high expression of aldehyde dehydrogenases (ALDHs), probably significant determinants of cell survival through their ability to detoxify many potentially cytotoxic molecules, and contributing to drug resistance. Antibodies are available against the ALDH enzyme family, but the vast majority of studies have used cell sorting techniques to enrich for cells expressing these enzymes. Live cells expressing high ALDH activity are usually identified by the ALDEFLUOR kit and sorted by fluorescence activated cell sorting (FACS). For many human tumours, but notably breast cancer, cell selection based upon ALDH activity appears to be a useful marker for enriching for cells with tumour‐initiating activity (presumed cancer stem cells) in immunodeficient mice, and indeed the frequency of so‐called ALDH^bri cells in many tumours can be an independent prognostic indicator.

Meaning-making and the matrix model: does one size really fit all?

Despite the multifocal complexity of the matrix model (C.R. Snyder & T.R. Elliott, this issue, pp. 1033-1054), its close correspondence with the theoretical dialectics and philosophy of clinical constructivism auger well for its capacity to articulate with existing approaches to graduate education in psychology. In this article points of contact are documented between the two approaches, and a caveat is included about the limits of the matrix model in ensuring greater relevance of clinical training to the settings in which contemporary professionals will work.     

Transfusion in sub‐Saharan Africa: does a Western model fit?

This review examines the current state of transfusion services in sub-Saharan Africa and presents the argument for and against the Western model of a centralised blood service with 100% voluntary non-remunerated blood donors as advocated by the World Health Organization. The current practice of family replacement donors in hospital-based blood service is the most economical option, but in the face of high child and maternal mortality rates the blood supply has proved to be insufficient. With estimates of 5-10% of HIV transmission in Africa being the result of contaminated blood transfusions, there is a need to improve testing for transfusion transmissible diseases and the selection of blood donors. Of major concern, with respect to testing, is the quality of kits being used and the continuity of supply. The need to produce components is discussed in the context of the transfusion needs in sub-Saharan Africa. The running costs of establishing and maintaining centralised blood services need careful consideration as such projects need to be sustainable in the future. It is concluded that both options are viable while centralised programmes are being developed, and a pragmatic approach should be taken to ensure that the patients' needs are met and that resources are suitably utilised to ensure sustainability.     

Patients' needs following colorectal cancer diagnosis: where does primary care fit in?

Background

Colorectal cancer is the third most common cancer in the UK. Patients with colorectal cancer spend most of their time in the community, but the role of primary care in their management and follow-up is unclear.

Aim

To explore colorectal cancer patients'' experiences of psychosocial problems and their management in primary and specialist care.

Design and setting

Longitudinal qualitative study of participants recruited from three hospitals in the west of Scotland and interviewed in their own homes.

Method

In-depth interviews with 24 participants with a new diagnosis of colorectal cancer, and then follow-up interviews 12 months later.

Results

Participants'' needs following a diagnosis for colorectal cancer included physical, psychological, and social issues. GPs played a key role in diagnosis, after which they were less involved. Participants valued GPs making unsolicited contact and offering support. Participants described being well supported by clinical nurse specialists who are expert in the illness, and who provide continuity of care and psychological support. A year after diagnosis, when there was less contact with GPs and clinical nurse specialists, participants still faced challenges associated with the ongoing impact of colorectal cancer

Conclusion

While some patients enjoyed straightforward recoveries from surgery, others experienced longer-term implications from their disease and treatment, particularly bowel-function issues, fatigue, anxiety, and sexual problems. The potential for primary care to contribute more to the ongoing care of colorectal cancer patients was identified.     

Cardiorespiratory fitness effect may be under-estimated in ‘fat but fit’ hypothesis studies

Background: Both cardiorespiratory fitness and body fat have been independently related to metabolic syndrome in adolescents; however, the strength of these relationships seems to be dependent on the outcome composition.

Aim: To analyse the relationship between cardiorespiratory fitness and body fat combined with different indicators of metabolic risk in adolescents.

Subjects and methods: The sample was composed of 957 adolescents (58.7% girls). Cardiorespiratory fitness was obtained using the 20-metre shuttle run test and skinfold thickness was collected for body fat estimation. Metabolic risk score was calculated from waist circumference, systolic and diastolic blood pressure, glucose, HDL cholesterol and triglycerides measurements and an alternative outcome without the central obesity indicator was adopted. Chronological age and somatic maturity were used as covariates.

Results: Higher metabolic risk was observed in the highest fat/lowest fit adolescents (p?Conclusion: These findings suggest that body fat is strongly related to cardiovascular risk, but, when the outcome is calculated without the central obesity indicator, cardiorespiratory fitness becomes more related to metabolic risk.     

Working towards a ‘fit note’: an experimental vignette survey of GPs

Background

The Department for Work and Pensions (DWP) has designed a trial medical statement.

Aim

To compare fitness for work assessment outcomes and written advice across current and trial medical statements. To examine the use of and suggestions to improve the trial medical statement.

Design of study

Comparative study with a two-way mixed design using questionnaire-based vignettes presenting GPs with three hypothetical sick leave cases (back pain, depression, combined back pain and depression) and medical statements (current or trial). The questionnaire also gathered GP views of using the trial Med 3.

Setting

Nine primary care organisations (PCOs) in England, Scotland, and Wales.

Method

Five hundred and eighty-three GPs employed in PCOs in summer 2008 were randomised to receive a current or trial Med 3 postal questionnaire. GPs assessed vignette patients'' fitness for work using the questionnaire medical statements.

Results

GPs using the trial Med 3 were less likely to advise refraining from work and more likely to provide written fitness for work advice compared to GPs using the current Med 3 form. Date sections of the trial Med 3 were used inconsistently, and a return to work date was unclear. GPs wanted further clarification of the implications of assessing a case as ‘fit for some work’ and its relationship to employers'' willingness to follow GP advice about work.

Conclusion

The study indicates a revised form may reduce the number of patients advised to refrain from work and increase the provision of written fitness for work information.     

Fit for purpose? Using the fit note with patients with chronic pain: a qualitative study

Background

Staying in work may benefit patients with chronic pain, but can be difficult for GPs to negotiate with patients and their employers. The new fit note is designed to help this process, but little is known of how it is operating.

Aim

To explore GPs'' views on the fit note, with particular reference to sickness certification for patients with chronic pain.

Design and setting

Qualitative study using semi-structured interviews in eight primary care trusts in south-west England.

Method

In-depth interviews with 13 GPs.

Results

GPs reported that the rationale behind the fit note is sound and that it may help patients with chronic pain to return to work earlier. However, GPs also reported barriers to successful fit note use, including the need to preserve doctor–patient relationships, inconsistent engagement from employers, GPs'' lack of specialist occupational health knowledge, issues with fit note training, and whether a new form can achieve cultural shift.

Conclusion

While doctors agree that good work improves health outcomes, they do not think that fit notes will greatly alter sickness-certification rates without more concerted initiatives to manage the tripartite negotiation between doctor, patient, and employer.     

HIV diversity, recombination and disease progression: how does fitness "fit" into the puzzle?

HIV appears to have diverged into several lineages upon multiple zoonotic introductions from the nonhuman primates. The HIV-2 and HIV-1 groups M, N, and O likely represent different cross-species transmission events. The radial evolution of group M in multiple clades or subtypes is likely due to adaptation and expansions in the human hosts. It is not well understood why HIV strains such as HIV-1 subtype C in particular or group M in general have spread disproportionately as compared to other subtypes, groups, or types, which often remained geographically constrained to local epidemics. Host genetic effects, transmission bottlenecks, social/behavioral and environmental limitations, founder effect and other viral factors could have contributed to variable spread through the human population. Even after transmission, viruses evolve at different rates during disease progression. Recent studies have explored phenotypic differences between HIV types, groups, and subtypes in attempts to explain or understand this radial evolution and expansion. This review explores some of the important aspects relating to fitness during disease progression, during global distribution of different HIV subtypes, and related to circulation of recombinant forms in the epidemic.     

Pediatric renal cell carcinomas: where do they fit in the new histologic classification of renal cell carcinoma?

Genetic, immunohistochemical, and histologic data has led to the reclassification of renal cell carcinoma in the last decade. Recent studies suggest that renal cell carcinomas in children and young adults may represent a distinct group of tumors. These tumors have unique genetic findings (most commonly t(x;1)(p11:q21)), a predominantly papillary architecture, numerous calcifications, granular cytoplasm, and a possible relationship with neuroblastoma.     

Changes in the control of skin blood flow with exercise training: where do cutaneous vascular adaptations fit in?

Heat is the most abundant byproduct of cellular metabolism. As such, dynamic exercise in which a significant percentage of muscle mass is engaged generates thermoregulatory demands that are met in part by increases in skin blood flow. Increased skin blood flow during exercise adds to the demands on cardiac output and confers additional circulatory strain beyond that associated with perfusion of active muscle alone. Endurance exercise training results in a number of physiological adaptations which ultimately reduce circulatory strain and shift thermoregulatory control of skin blood flow to higher levels of blood flow for a given core temperature. In addition, exercise training induces peripheral vascular adaptations within the cutaneous microvasculature indicative of enhanced endothelium-dependent vasomotor function. However, it is not currently clear how (or if) these local vascular adaptations contribute to the beneficial changes in thermoregulatory control of skin blood flow following exercise training. The purpose of this Hot Topic Review is to synthesize the literature pertaining to exercise training-mediated changes in cutaneous microvascular reactivity and thermoregulatory control of skin blood flow. In addition, we address mechanisms driving changes in cutaneous microvascular reactivity and thermoregulatory control of skin blood flow, and pose the question: what (if any) is the functional role of increased cutaneous microvascular reactivity following exercise training?
