Quality in qualitative research.

Abstract: Qualitative research most commonly involves the systematic collection, ordering, description and interpretation of textual data generated from talk, observation or documentation. A report of qualitative research should address the following criteria: Clarification and justification; Procedural rigour; Representativeness; Interpretative rigour; Reflexivity and evaluative rigour; and Transferability. Because of the limitations on article length for the Medical Journal of Australia, authors should focus on only a couple of aspects of the research, rather than trying to present a simplified description of multiple aspects.

Development of a compendium of energy expenditures for youth.

Abstract: Background: This paper presents a Compendium of Energy Expenditures for use in scoring physical activity questionnaires and estimating energy expenditure levels in youth. Method/Results: Modeled after the adult Compendium of Physical Activities, the Compendium of Energy Expenditures for Youth contains a list of over 200 activities commonly performed by youth and their associated MET intensity levels. A review of existing data collected on the energy cost of youth performing activities was undertaken and incorporated into the compendium. About 35% of the activity MET levels were derived from energy cost data measured in youth and the remaining MET levels estimated from the adult compendium. Conclusion: The Compendium of Energy Expenditures for Youth is useful to researchers and practitioners interested in identifying physical activity and energy expenditure values in children and adolescents in a variety of settings.

Microbial Ecology of Four Coral Atolls in the Northern Line Islands

Abstract: Microbes are key players in both healthy and degraded coral reefs. A combination of metagenomics, microscopy, culturing, and water chemistry were used to characterize microbial communities on four coral atolls in the Northern Line Islands, central Pacific. Kingman, a small uninhabited atoll which lies most northerly in the chain, had microbial and water chemistry characteristic of an open ocean ecosystem. On this atoll the microbial community was equally divided between autotrophs (mostly Prochlorococcus spp.) and heterotrophs. In contrast, Kiritimati, a large and populated (~5500 people) atoll, which is most southerly in the chain, had microbial and water chemistry characteristic of a near-shore environment. On Kiritimati, there were 10 times more microbial cells and virus-like particles in the water column and these microbes were dominated by heterotrophs, including a large percentage of potential pathogens. Culturable Vibrios were common only on Kiritimati. The benthic community on Kiritimati had the highest prevalence of coral disease and lowest coral cover. The middle atolls, Palmyra and Tabuaeran, had intermediate densities of microbes and viruses and higher percentages of autotrophic microbes than either Kingman or Kiritimati. The differences in microbial communities across atolls could reflect variation in 1) oceaonographic and/or hydrographic conditions or 2) human impacts associated with land-use and fishing. The fact that historically Kingman and Kiritimati did not differ strongly in their fish or benthic communities (both had large numbers of sharks and high coral cover) suggest an anthropogenic component in the differences in the microbial communities. Kingman is one of the world's most pristine coral reefs, and this dataset should serve as a baseline for future studies of coral reef microbes. Obtaining the microbial data set, from atolls is particularly important given the association of microbes in the ongoing degradation of coral reef ecosystems worldwide.

The Effect of Thin Ideal Media Images on Women's Self-Objectification, Mood, and Body Image

Abstract: Objectification theory (Fredrickson and Roberts, Psychology of Women Quarterly, 21, 173–206, 1997) contends that experiences of sexual objectification socialize women to engage in self-objectification. The present study used an experimental design to examine the effects of media images on self-objectification. A total of 90 Australian undergraduate women aged 18 to 35 were randomly allocated to view magazine advertisements featuring a thin woman, advertisements featuring a thin woman with at least one attractive man, or advertisements in which no people were featured. Participants who viewed advertisements featuring a thin-idealized woman reported greater state self-objectification, weight-related appearance anxiety, negative mood, and body dissatisfaction than participants who viewed product control advertisements. The results demonstrate that self-objectification can be stimulated in women without explicitly focusing attention on their own bodies.

Retributive and restorative justice

Abstract: The emergence of restorative justice as an alternative model to Western, court-based criminal justice may have important implications for the psychology of justice. It is proposed that two different notions of justice affect responses to rule-breaking: restorative and retributive justice. Retributive justice essentially refers to the repair of justice through unilateral imposition of punishment, whereas restorative justice means the repair of justice through reaffirming a shared value-consensus in a bilateral process. Among the symbolic implications of transgressions, concerns about status and power are primarily related to retributive justice and concerns about shared values are primarily related to restorative justice. At the core of these processes, however, lies the parties’ construal of their identity relation, specifically whether or not respondents perceive to share an identity with the offender. The specific case of intergroup transgressions is discussed, as are implications for future research on restoring a sense of justice after rule-breaking.

Asia Pacific consensus recommendations for colorectal cancer screening

Abstract: Colorectal cancer (CRC) is rapidly increasing in Asia, but screening guidelines are lacking. Through reviewing the literature and regional data, and using the modified Delphi process, the Asia Pacific Working Group on Colorectal Cancer and international experts launch consensus recommendations aiming to improve the awareness of healthcare providers of the changing epidemiology and screening tests available. The incidence, anatomical distribution and mortality of CRC among Asian populations are not different compared with Western countries. There is a trend of proximal migration of colonic polyps. Flat or depressed lesions are not uncommon. Screening for CRC should be started at the age of 50 years. Male gender, smoking, obesity and family history are risk factors for colorectal neoplasia. Faecal occult blood test (FOBT, guaiac-based and immunochemical tests), flexible sigmoidoscopy and colonoscopy are recommended for CRC screening. Double-contrast barium enema and CT colonography are not preferred. In resource-limited countries, FOBT is the first choice for CRC screening. Polyps 5-9 mm in diameter should be removed endoscopically and, following a negative colonoscopy, a repeat examination should be performed in 10 years. Screening for CRC should be a national health priority in most Asian countries. Studies on barriers to CRC screening, education for the public and engagement of primary care physicians should be undertaken. There is no consensus on whether nurses should be trained to perform endoscopic procedures for screening of colorectal neoplasia.

The relationship between sensory processing patterns and behavioural responsiveness in autistic disorder: A pilot study.

Abstract: Sensory processing (SP) difficulties have been reported in as many as 95% of children with autism, however, empirical research examining the existence of specific patterns of SP difficulties within this population is scarce. Furthermore, little attention has been given to examining the relationship between SP and either the core symptoms or secondary manifestations of autism. In the current study, SP patterns in children with autistic disorder (AD) were investigated via a caregiver questionnaire and findings were correlated with the social, emotional and behavioural responsiveness of participants. Results indicated the presence of specific SP patterns in this sample of children with AD and several significant relationships were found between SP and social, emotional and behavioural function.

Endophytic Actinobacteria Induce Defense Pathways in Arabidopsis thaliana

Abstract: Endophytic actinobacteria, isolated from healthy wheat tissue, which are capable of suppressing a number wheat fungal pathogens both in vitro and in planta, were investigated for the ability to activate key genes in the systemic acquired resistance (SAR) or the jasmonate/ethylene (JA/ET) pathways in Arabidopsis thaliana. Inoculation of A. thaliana (Col-0) with selected endophytic strains induced a low level of SAR and JA/ET gene expression, measured using quantitative polymerase chain reaction. Upon pathogen challenge, endophyte-treated plants demonstrated a higher abundance of defense gene expression compared with the non-endophyte-treated controls. Resistance to the bacterial pathogen Erwinia carotovora subsp. carotovora required the JA/ET pathway. On the other hand, resistance to the fungal pathogen Fusarium oxysporum involved primarily the SAR pathway. The endophytic actinobacteria appear to be able to "prime" both the SAR and JA/ET pathways, upregulating genes in either pathway depending on the infecting pathogen. Culture filtrates of the endophytic actinobacteria were investigated for the ability to also activate defense pathways. The culture filtrate of Micromonospora sp. strain EN43 grown in a minimal medium resulted in the induction of the SAR pathway; however, when grown in a complex medium, the JA/ET pathway was activated. Further analysis using Streptomyces sp. strain EN27 and defense-compromised mutants of A. thaliana indicated that resistance to E. carotovora subsp. carotovora occurred via an NPR1-independent pathway and required salicylic acid whereas the JA/ET signaling molecules were not essential. In contrast, resistance to F. oxysporum mediated by Streptomyces sp. strain EN27 occurred via an NPR1-dependent pathway but also required salicylic acid and was JA/ET independent.

Sustaining hope when communicating with terminally ill patients and their families: a systematic review.

Abstract: The aim of this systematic review was to examine studies that have investigated sustaining hope during prognostic and end-of-life issues discussions with terminally ill patients and their families. A comprehensive search of databases (MEDLINE, EMBASE, CINAHL, PsychINFO, Cochrane Central Register of Controlled Trials) and handsearching, from 1985 to June 2006, identified 27 studies. This review suggests that the issues surrounding hope in this context are complex. Despite the lack of unanimity among researchers regarding the definition of hope, findings suggest that balancing hope with honesty is an important skill for health professionals (HPs). Many patients seem to be able to maintain a sense of hope despite acknowledging the terminal nature of their illness. Patients and caregivers mostly preferred honest and accurate information, provided with empathy and understanding. Many different sources of hope were identified in this context in broad aspects of life, not just the medical situation. HPs need to recognize this spectrum of hope and appreciate that patients may simultaneously hope for 'cure' while acknowledging the terminal nature of their illness. HPs may help patients to cope with their terminal prognosis by exploring and fostering realistic forms of hope that are meaningful for the particular patient and their family.

Relationships between the home environment and physical activity and dietary patterns of preschool children: a cross-sectional study

Abstract: To assess relationships between characteristics of the home environment and preschool children's physical activity and dietary patterns. Homes of 280 preschool children were visited and information obtained by direct observation and parent interview regarding physical and nutritional characteristics of the home environment. Children's physical activity, sedentary behaviour and dietary patterns were measured using standardised parent-report questionnaires. Associations were analysed using analysis of variance and correlation. Parental physical activity (p = 0.03–0.008), size of backyard (p = 0.001) and amount of outdoor play equipment (p = 0.003) were associated with more outdoor play. Fewer rules about television viewing (p < 0.001) and presence of playstation (p = 0.02) were associated with more indoor sedentary time. Higher fruit and vegetable intake was associated with restricting children's access to fruit juice (p = 0.02) and restricting high fat/sugar snacks (p = 0.009). Lower intake of non-core foods was associated with restricting children's access to fruit juice (p = 0.007), cordial/carbonated drinks (p < 0.001) and high fat/sugar snacks (p = 0.003). Lower fruit and vegetable intake was associated with reminding child to 'eat up' (p = 0.007) and offering food rewards to eat main meal (p = 0.04). Higher intake of non-core foods was associated with giving food 'treats' (p = 0.03) and offering food rewards to eat main meal (p = 0.04). The availability of food groups in the home was associated with children's intake of these foods (fruit and vegetables, p < 0.001; fat in dairy, p = <0.001; sweetened beverages, p = 0.004–<0.001; non-core foods, p = 0.01–<0.001). Physical attributes of the home environment and parental behaviours are associated with preschool children's physical activity, sedentary behaviour and dietary patterns. Many of these variables are modifiable and could be targeted in childhood obesity prevention and management.

The importance of early complementary feeding in the development of oral tolerance: Concerns and controversies

Abstract: Rising rates of food allergies in early childhood reflect increasing failure of early immune tolerance mechanisms. There is mounting concern that the current recommended practice of delaying complementary foods until 6 months of age may increase, rather than decrease, the risk of immune disorders. Tolerance to food allergens appears to be driven by regular, early exposure to these proteins during a 'critical early window' of development. Although the timing of this window is not clear in humans, current evidence suggests that this is most likely to be between 4 and 6 months of life and that delayed exposure beyond this period may increase the risk of food allergy, coeliac disease and islet cell autoimmunity. There is also evidence that other factors such as favourable colonization and continued breastfeeding promote tolerance and have protective effects during this period when complementary feeding is initiated. This discussion paper explores the basis for concern over the current recommendation to delay complementary foods as an approach to preventing allergic disease. It will also examine the growing case for introducing complementary foods from around 4 months of age and maintaining breastfeeding during this early feeding period, for at least 6 months if possible.

Motherhood: A Potential Source of Bias in Employment Decisions

Abstract: Results of 2 experimental studies in which job incumbents were said to be applying for promotions to traditionally male positions demonstrated bias against mothers in competence expectations and in screening recommendations. This bias occurred regardless of whether the research participants were students (Study 1) or working people (Study 2). Although anticipated job commitment, achievement striving, and dependability were rated as generally lower for parents than for nonparents, anticipated competence was uniquely low for mothers. Mediational analyses indicated that, as predicted, negativity in competence expectations, not anticipated job commitment or achievement striving, promoted the motherhood bias in screening recommendations; expected deficits in agentic behaviors, not in dependability, were found to fuel these competence expectations. These findings suggest that motherhood can indeed hinder the career advancement of women and that it is the heightened association with gender stereotypes that occurs when women are mothers that is the source of motherhood's potentially adverse consequences.

Comparative metagenomics reveals host specific metavirulomes and horizontal gene transfer elements in the chicken cecum microbiome.

Abstract: Background The complex microbiome of the ceca of chickens plays an important role in nutrient utilization, growth and well-being of these animals. Since we have a very limited understanding of the capabilities of most species present in the cecum, we investigated the role of the microbiome by comparative analyses of both the microbial community structure and functional gene content using random sample pyrosequencing. The overall goal of this study was to characterize the chicken cecal microbiome using a pathogen-free chicken and one that had been challenged with Campylobacter jejuni. Methodology/Principal Findings Comparative metagenomic pyrosequencing was used to generate 55,364,266 bases of random sampled pyrosequence data from two chicken cecal samples. SSU rDNA gene tags and environmental gene tags (EGTs) were identified using SEED subsystems-based annotations. The distribution of phylotypes and EGTs detected within each cecal sample were primarily from the Firmicutes, Bacteroidetes and Proteobacteria, consistent with previous SSU rDNA libraries of the chicken cecum. Carbohydrate metabolism and virulence genes are major components of the EGT content of both of these microbiomes. A comparison of the twelve major pathways in the SEED Virulence Subsystem (metavirulome) represented in the chicken cecum, mouse cecum and human fecal microbiomes showed that the metavirulomes differed between these microbiomes and the metavirulomes clustered by host environment. The chicken cecum microbiomes had the broadest range of EGTs within the SEED Conjugative Transposon Subsystem, however the mouse cecum microbiomes showed a greater abundance of EGTs in this subsystem. Gene assemblies (32 contigs) from one microbiome sample were predominately from the Bacteroidetes, and seven of these showed sequence similarity to transposases, whereas the remaining sequences were most similar to those from catabolic gene families. Conclusion/Significance This analysis has demonstrated that mobile DNA elements are a major functional component of cecal microbiomes, thus contributing to horizontal gene transfer and functional microbiome evolution. Moreover, the metavirulomes of these microbiomes appear to associate by host environment. These data have implications for defining core and variable microbiome content in a host species. Furthermore, this suggests that the evolution of host specific metavirulomes is a contributing factor in disease resistance to zoonotic pathogens.

Exploring nutrition knowledge and the demographic variation in knowledge levels in an Australian community sample.

Abstract: ObjectivesExplore the level of general nutrition knowledge and demographic influences of knowledge levels in a community sample.Design and settingA sample of volunteers, recruited from community centres in two suburbs of differing socio-economic status, in Adelaide, South Australia.SubjectsTwo hundred and one people, aged 18 years and older, completed a modified and validated version of the General Nutrition Knowledge Questionnaire (113 items). The questionnaire was self-administered and completed under supervision.ResultsBasic messages about eating more fruit, vegetables and fibre, and less fatty and salty foods were best understood. Confusion was evident with more detailed nutrition information. For example, 90 % of the people were aware of the recommendations to eat more fruit and vegetables, but 56 % and 62 % knew the recommended number of servings of fruit and vegetables, respectively. Descriptive statistics showed significant demographic variation in nutrition knowledge levels; multiple regression analysis confirmed the significant independent effects of gender, age, highest level of education and employment status on nutrition knowledge level (P < 0·01 level). The model accounted for 40 % of the variance in nutrition knowledge scores.ConclusionsThere is demographic variation in nutrition knowledge levels and a broad lack of awareness of some public health nutrition recommendations. Having a detailed understanding of the deficiencies in community knowledge should allow for future nutrition education programmes to target subgroups of the population or particular areas of nutrition education, to more efficiently improve knowledge and influence dietary behaviour.

Isolation of mitochondria from rat brain using Percoll density gradient centrifugation.

Abstract: We have developed procedures that combine differential centrifugation and discontinuous Percoll density gradient centrifugation to isolate mitochondria from rat forebrains and brain subregions. The use of Percoll density gradient centrifugation is central to obtaining preparations that contain little contamination with synaptosomes and myelin. Protocols are presented for three variations of this procedure that differ in their suitability for dealing with large or small samples, in the proportion of total mitochondria isolated and in the total preparation time. One variation uses digitonin to disrupt synaptosomes before mitochondrial isolation. This method is well suited for preparing mitochondria from small tissue samples, but the isolated organelles are not appropriate for all studies. Each of the procedures produces mitochondria that are well coupled and exhibit high rates of respiratory activity. The procedures require an initial setup time of 45–75 min and between 1 and 3 h for the mitochondrial isolation.

Preference for place of care and place of death in palliative care: are these different questions?:

Abstract: Place of death is at times suggested as an outcome for palliative care services. This study aimed to describe longitudinal preferences for place of care and place of death over time for patients and their caregivers. Longitudinal paired data of patient/caregiver dyads from a prospective unblinded cluster randomised control trial were used. Patients and caregivers were separately asked by the palliative care nurse their preference at that time for place of care and place of death. Longitudinal changes over time for both questions were mapped; patterns of agreement (patient and caregiver; and preference for place of death when last asked and actual placed of death) were analysed with kappa statistics. Seventy-one patient/caregiver dyads were analysed. In longitudinal preferences, preferences for both the place of care (asked a mean of >6 times) and place of death (asked a mean of >4 times) changed for patients (28% and 30% respectively) and caregivers (31% and 30%, respectively). In agreement between patients and caregivers, agreement between preference of place of care and preferred place of death when asked contemporaneously for patients and caregivers was low [56% (kappa 0.33) and 36% (kappa 0.35) respectively]. In preference versus actual place of death, preferences were met for 37.5% of participants for home death; 62.5% for hospital; 76.9% for hospice and 63.6% for aged care facility. This study suggests that there are two conversations: preference for current place of care and preference for care at the time of death. Place of care is not a euphemism for place of death; and further research is needed to delineate these. Patient and caregiver preferences may not change simultaneously. Implications of any mismatch between actual events and preferences need to be explored.

Risk factors for human corneal graft failure within the Australian corneal graft registry.

Abstract: Background Our aims were to examine graft survival and visual outcome after full-thickness corneal transplantation. Methods Records of 18,686 penetrating corneal grafts, 14,622 with archival follow-up from 1 to 22 years, were examined within a national database. Kaplan-Meier survival analysis indicated variables of interest for Cox proportional hazards regression analysis. A model clustered by patient to control intereye or intergraft dependence was constructed to identify variables best predicting penetrating corneal graft failure. Visual acuity in the grafted eye was measured by Snellen acuity. Results Probability of corneal graft survival was 0.87, 0.73, 0.60, and 0.46 at 1, 5, 10, and 15 years, respectively. Reasons for graft failure included irreversible rejection (34%), corneal endothelial cell failure including cases of glaucoma (24%), and infection (14%). Variables predicting graft failure in multivariate analysis included transplant center, location and volume of surgeon's case-load, graft era, indication for graft, number of previous ipsilateral grafts, lens status, corneal neovascularization at transplantation, a history of ocular inflammation or raised intraocular pressure, graft diameter, and postoperative events including graft neovascularization and rejection. Best-corrected Snellen acuity of 6/12 or better was achieved by 45%, and of less than 6/60 by 26%, of grafted eyes at last follow-up. Conclusions The short-term survival of penetrating corneal transplants is excellent, but the eventual attrition rate appears inexorable and many factors that influence graft survival significantly are not amenable to change. Most penetrating grafts are performed for visual improvement, and excellent acuity will be achieved by approximately half of all grafts.

Purification, molecular cloning, and characterization of glutathione S-transferases (GSTs) from pigmented Vitis vinifera L. cell suspension cultures as putative anthocyanin transport proteins

Abstract: The ligandin activity of specific glutathione S-transferases (GSTs) is necessary for the transport of anthocyanins from the cytosol to the plant vacuole. Five GSTs were purified from Vitis vinifera L. cv. Gamay Freaux cell suspension cultures by glutathione affinity chromatography. These proteins underwent Edman sequencing and mass spectrometry fingerprinting, with the resultant fragments aligned with predicted GSTs within public databases. The corresponding coding sequences were cloned, with heterologous expression in Escherichia coli used to confirm GST activity. Transcriptional profiling of these candidate GST genes and key anthocyanin biosynthetic pathway genes (PAL, CHS, DFR, and UFGT) in cell suspensions and grape berries against anthocyanin accumulation demonstrated strong positive correlation with two sequences, VvGST1 and VvGST4, respectively. The ability of VvGST1 and VvGST4 to transport anthocyanins was confirmed in the heterologous maize bronze-2 complementation model, providing further evidence for their function as anthocyanin transport proteins in grape cells. Furthermore, the differential induction of VvGST1 and VvGST4 in suspension cells and grape berries suggests functional differences between these two proteins. Further investigation of these candidate ligandins may identify a mechanism for manipulating anthocyanin accumulation in planta and in vitro suspension cells.

Depression: An Important Comorbidity With Metabolic Syndrome in a General Population

Abstract: OBJECTIVE —There is a recognized association among depression, diabetes, and cardiovascular disease. The aim of this study was to examine in a sample representative of the general population whether depression, anxiety, and psychological distress are associated with metabolic syndrome and its components. RESEARCH DESIGN AND METHODS —Three cross-sectional surveys including clinical health measures were completed in rural regions of Australia during 2004–2006. A stratified random sample ( n = 1,690, response rate 48%) of men and women aged 25–84 years was selected from the electoral roll. Metabolic syndrome was defined by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults, Adult Treatment Panel III (NCEP ATP III), and International Diabetes Federation (IDF) criteria. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale and psychological distress by the Kessler 10 measure. RESULTS —Metabolic syndrome was associated with depression but not psychological distress or anxiety. Participants with the metabolic syndrome had higher scores for depression ( n = 409, mean score 3.41, 95% CI 3.12–3.70) than individuals without the metabolic syndrome ( n = 936, mean 2.95, 95% CI 2.76–3.13). This association was also present in 338 participants with the metabolic syndrome and without diabetes (mean score 3.37, 95% CI 3.06–3.68). Large waist circumference and low HDL cholesterol showed significant and independent associations with depression. CONCLUSIONS —Our results show an association between metabolic syndrome and depression in a heterogeneous sample. The presence of depression in individuals with the metabolic syndrome has implications for clinical management.

The solubility of α‐synuclein in multiple system atrophy differs from that of dementia with Lewy bodies and Parkinson's disease

Abstract: Intracellular inclusions containing alpha-synuclein (alpha SN) are pathognomonic features of several neurodegenerative disorders. Inclusions occur in oligodendrocytes in multiple system atrophy (MSA) and in neurons in dementia with Lewy bodies (DLB) and Parkinson's disease (PD). In order to identify disease-associated changes of alpha SN, this study compared the levels, solubility and molecular weight species of alpha SN in brain homogenates from MSA, DLB, PD and normal aged controls. In DLB and PD, substantial amounts of detergent-soluble and detergent-insoluble alpha SN were detected compared with controls in grey matter homogenate. Compared with controls, MSA cases had significantly higher levels of alpha SN in the detergent-soluble fraction of brain samples from pons and white matter but detergent-insoluble alpha SN was not detected. There was an inverse correlation between buffered saline-soluble and detergent-soluble levels of alpha SN in individual MSA cases suggesting a transition towards insolubility in disease. The differences in solubility of alpha SN between grey and white matter in disease may result from different processing of alpha SN in neurons compared with oligodendrocytes. Highly insoluble alpha SN is not involved in the pathogenesis of MSA. It is therefore possible that buffered saline-soluble or detergent-soluble forms of alpha SN are involved in the pathogenesis of other alpha SN-related diseases.

The role of self-objectification in women's sexual functioning.

Abstract: The study aimed to test the model proposed by objectification theory (Fredrickson & Roberts, 1997) as it applies to women's sexual functioning. A sample of 116 women completed questionnaire measures of self-objectification, its proposed consequences, relationship satisfaction, and sexual functioning. In accord with the predictions of the theory, self-objectification was related to body shame and appearance anxiety, which were in turn related to self-consciousness during sexual activity and to decreased sexual functioning. Women in an exclusive relationship reported less self-consciousness during sexual activity than women not in a relationship. For the former group, satisfaction with their relationship emerged as the major predictor of sexual functioning. It was concluded that objectification theory provides a useful framework for furthering our understanding of female sexual function.

Workplace violence directed at nursing staff at a general hospital in southern Thailand.

Abstract: This study aimed to document the characteristics of workplace violence directed at nursing staff, an issue which has rarely been studied in a developing country. Two study methods, a survey and a key informant interview, were conducted at a general hospital in southern Thailand. A total of 545 out of 594 questionnaires sent were returned for statistical analysis (response rate=91.7%). The 12-month prevalence of violence experience was 38.9% for verbal abuse, 3.1% for physical abuse, and 0.7% for sexual harassment. Psychological consequences including poor relationships with colleagues and family members were the major concerns. Patients and their relatives were the main perpetrators in verbal and physical abuse while co-workers were the main perpetrators in cases of sexual harassment. Common factors to incidents of violence were psychological setting, illness of the perpetrators, miscommunication, and alcohol use. Logistic regression analysis showed younger age to be a personal risk factor. Working in the out-patient unit, trauma and emergency unit, operating room, or medical or surgical unit increased the odds of violence by 80%. Training related to violence prevention and control was found to be effective and decreased the risk of being a victim of violence by 40%. We recommend providing training to high risk groups as a means of controlling workplace violence directed at nursing staff.
