Cracked Tooth Syndrome: Assessment, Prognosis and Predictable Management Strategies

Cracked tooth syndrome (CTS) is a common presentation in general practice. The diagnosis and management of teeth with CTS may be difficult due to the unknown extent of the crack. This article reviews the aetiology, diagnosis, management and prognosis of teeth with CTS. A thorough examination is required to effectively assess CTS. Intervention should aim to relieve symptoms and brace the remaining tooth structure effectively against further flexion. Restored teeth with CTS have a guarded prognosis due to the risk of further crack propagation, but the chances of survival at 5-years is acceptable (74.1-96.8%).

Digital health screening tool for identification of elder mistreatment

PURPOSE

It is estimated that 15.7% of people aged 60 years and older were subjected to some form of Elder Mistreatment (EM) globally (Yon et al., 2017). In the USA, as many as 1 in 24 EM cases are left unidentified by professionals, with a 300% increased mortality risk for older adults who do not receive help (National Center on Elder Abuse, n.d.; Dong, 2009). Current methods of screening tend to miss less obvious signs of EM and may discourage older adults from disclosing EM, due to either a lack of understanding of what constitutes mistreatment or fear of retaliation from the perpetrator.

METHOD

Our approach shifts the focus of EM identification to the older adults themselves through an automated tablet-based tool. The Virtual cOaching in making Informed Choices on Elder Mistreatment Self-Disclosure (VOICES) tool includes various multimedia components such as videos, audio, and animations designed to educate and enhance screening. Patients screened as positive are guided through a Brief Negotiated Interview (BNI) utilizing motivational interviewing to assist in self-identification (recognize that they are experiencing elder mistreatment) or self-disclosure (inform others about their elder mistreatment experiences). During tool development, we conducted a qualitative study to evaluate the perceived value and likelihood of adopting a tablet-based approach to facilitate screening and self-disclosure of EM in the ED. We held 3 focus groups with stakeholders, including 24 adults 60 years or over, 2 social workers, 2 caregivers, and 2 ED clinicians. We used the findings from the focus groups and User-Centered Design approach (UCD) to develop the tablet-based screening tool. Once the tool was ready, we tested its usability and acceptability with 14 older adults.

RESULTS AND DISCUSSION

Focus group participants supported use of a tablet-based tool to screen for EM, indicating that digital screening benefits from feelings of privacy and anonymity. On a 7-point Likert scale ranging from "1=Very Comfortable" to "7=Very Uncomfortable", older adults scored 2.8 on average for whether they would feel comfortable using a tablet device to screen for EM. Prominent suggestions made by older adults included using a female voice for the tool narrator, larger font size, more multimedia, headphones for privacy; and having someone available during screening for assistance if needed. Participants indicated that it is difficult for older adults experiencing EM to ask for help and that any type of mistreatment screening would be helpful. They also highlighted the need to explain community resources available to older adults once EM is disclosed, especially resources offering help to the caregiver. Participants of the usability evaluation rated the tool a mean score of 86.6 (median= 88.8, iQR =18.1) on the System Usability Scale (SUS), far above the benchmark SUS score of 68, which indicates that the system is "good" or "acceptable" (Bangor et al., 2008). Shifting the focus from the provider to the older adult may encourage self-disclosure of EM by addressing major barriers to traditional screening processes. In summary, this study supported the use of self-administered automated tablet-based screening for EM. Participants generally believed that the use of digital health tools to facilitate the screening process would be beneficial in the ED setting.

Increasing the sensitivity of terahertz split ring resonator metamaterials for dielectric sensing by localized substrate etching

We demonstrate a significant enhancement in the sensitivity of split ring resonator terahertz metamaterial dielectric sensors by the introduction of etched trenches into their inductive-capacitive gap area, both through finite element simulations and in experiments performed using terahertz time-domain spectroscopy. The enhanced sensitivity is demonstrated by observation of an increased frequency shift in response to overlaid dielectric material of thicknesses up to 18 µm deposited on to the sensor surface. We show that sensitivity to the dielectric is enhanced by a factor of up to ∼2.7 times by the incorporation of locally etched trenches with a depth of ∼3.4 µm, for example, and discuss the effect of the etching on the electrical properties of the sensors. Our experimental findings are in good agreement with simulations of the sensors obtained using finite element methods.

Use of The Global Alliance for Musculoskeletal Health survey module for estimating the population prevalence of musculoskeletal pain: findings from the Solomon Islands

Background

Musculoskeletal (MSK) conditions are common and the biggest global cause of physical disability. The objective of the current study was to estimate the population prevalence of MSK-related pain using a standardized global MSK survey module for the first time.

Methods

A MSK survey module was constructed by the Global Alliance for Musculoskeletal Health Surveillance Taskforce and the Global Burden of Disease MSK Expert Group. The MSK module was included in the 2015 Solomon Islands Demographic and Health Survey. The sampling design was a two-stage stratified, nationally representative sample of households.

Results

A total of 9214 participants aged 15–49 years were included in the analysis. The age-standardized four-week prevalence of activity-limiting low back pain, neck pain, and hip and/or knee pain was 16.8, 8.9, and 10.8%, respectively. Prevalence tended to increase with age, and be higher in those with lower levels of education.

Conclusions

Prevalence of activity-limited pain was high in all measured MSK sites. This indicates an important public health issue for the Solomon Islands that needs to be addressed. Efforts should be underpinned by integration with strategies for other non-communicable diseases, aging, disability, and rehabilitation, and with other sectors such as social services, education, industry, and agriculture. Primary prevention strategies and strategies aimed at self-management are likely to have the greatest and most cost-effective impact.

Management of Musculoskeletal Conditions in Rural South Australia: A Randomised Controlled Trial

With age, the prevalence of musculoskeletal conditions increases markedly. This rural-based study determined the benefits of two approaches for managing musculoskeletal conditions: a multiple-component 'Self-management Plus' intervention, and usual care. The intervention combined self-management education with physical activity and health professional support. 6-month outcomes included: Clinical Global Impression-Improvement Scale (CGI-IS) and Quality of Life (QoL). A total of 145 people were recruited; mean (SD) age was 66.1 (11.1) and 63.3 (10.9) years for intervention and control groups respectively. The intervention resulted in greater improvements in global functioning (CGI-IS mean (SD) = 3.2 (1.3)) than usual care (CGI-IS mean (SD) = 4.2 (1.5)). There was no difference in QoL improvement between study groups. A multiple-component 'Self-management Plus' intervention had a positive effect on physical functioning for older adults with musculoskeletal conditions. However, recruitment and retention of participants was problematic, which raises questions about the intervention's feasibility in its current form.

Identification of factors contributing to successful self-directed weight loss: a qualitative study

BACKGROUND

Despite the number of weight management programmes and their wide promotion, most overweight and obese individuals tend to lose weight on their own. The present study aimed to understand the characteristics and strategies of those who successfully engage in self-directed weight loss, which could empower other overweight and obese individuals with information and strategies to manage their weight on their own.

METHODS

Men and women who had lost at least 5% of their body weight without direct interaction with professionals or weight management programmes were recruited. Demographic data were collected by questionnaire and participants' weight-loss experiences were explored using semi- structured interviews to elicit in-depth individual experiences and perspectives. Iterative thematic method data analysis was used to generate themes describing contributing factors to the success of self-directed weight loss identified by participants.

RESULTS

Most characteristics of those who successfully self-managed their weight loss were in line with those reported by successful weight losers participating in professional-led projects. However, strategies such as early embedding of new lifestyle behaviours into daily routine, the ability to learn from previous weight-loss experiences, and not requiring social support were identified as distinctive factors that contributed to the success of self-directed weight loss by participants of the present study.

CONCLUSIONS

Overweight or obese individuals with strong internal motivation, problem-solving skills and self-reliance are more likely to be successful at achieving self-directed weight loss. The patients identified with these characteristics could be encouraged to self-manage their weight-loss process, leaving the places available in more resource-intensive professional-led programmes to those individuals unlikely to succeed on their own.

Obesity, arterial function and arterial structure - a systematic review and meta-analysis

OBJECTIVE

Obesity is an established risk factor for cardiovascular disease. The mechanisms by which obesity affects cardiovascular risk have not been fully elucidated. This paper reports a comprehensive systematic review and meta-analysis on obesity and two key aspects of vascular health using gold-standard non-invasive measures - arterial endothelial function (brachial flow-mediated dilatation) and subclinical atherosclerosis (carotid intima-media thickness).

METHODS

Electronic searches for 'Obesity and flow-mediated dilatation' and 'Obesity and intima-media thickness' were performed using Ovid Medline and Embase databases. A meta-analysis was undertaken for brachial flow-mediated dilatation and carotid intima-media thickness to obtain pooled estimates for adults with obesity and those with healthy weight.

RESULTS

Of the 5,810 articles retrieved, 19 studies on flow-mediated dilatation and 19 studies on intima-media thickness were included. Meta-analysis demonstrated that obesity was associated with lower flow-mediated dilatation (-1.92 % [95% CI -2.92, -0.92], P = 0.0002) and greater carotid intima-media thickness (0.07 mm [95% CI 0.05, 0.08], P < 0.0001).

CONCLUSIONS

Obesity is associated with poorer arterial endothelial function and increased subclinical atherosclerosis, consistent with these aspects of vascular health at least partially contributing to the increased risk of cardiovascular events in adults with obesity. These estimated effect sizes will enable vascular health benefits in response to weight loss treatment to be put in greater perspective, both in the research setting and potentially also clinical practice.

Validity of short food questionnaire items to measure intake in children and adolescents: a systematic review

BACKGROUND

Short food questions are appealing to measure dietary intakes.

METHODS

A review of studies published between 2004 and 2016 was undertaken and these were included in the present study if they reported on a question or short item questionnaire (≤50 items, data presented as ≤30 food groups) measuring food intake or food-related habits, in children (aged 6 months to 18 years), and reported question validity or reliability. Thirty studies met the inclusion criteria.

RESULTS

Most questions assessed foods or food groups (n = 29), with the most commonly assessed being fruit (n = 22) or vegetable intake (n = 23), dairy foods and discretionary foods (n = 20 studies each). Four studies assessed food habits, with the most common being breakfast and meal frequency (n = 4 studies). Twenty studies assessed reliability, and 25 studies determined accuracy and were most commonly compared against food records. Evaluation of question performance relied on statistical tests such as correlation.

CONCLUSIONS

The present study has identified valid and reliable questions for the range of key food groups of interest to public health nutrition. Questions were more likely to be reliable than accurate, and relatively few questions were both reliable and accurate. Gaps in repeatable and valid short food questions have been identified that will provide direction for future tool development.

Television advertising, not viewing, is associated with negative dietary patterns in children

BACKGROUND

Children's exposure to unhealthy food marketing is a contributor to poor diets and weight gain. Television food advertising, in particular, has been the focus of research and policy discussions.

OBJECTIVES

We aimed to quantify the specific impact of television advertising, as distinct from television viewing generally, on children's usual diet. Methods Four hundred seventeen Australian children aged 10-16 participated in an online survey, which assessed television viewing habits and consumption of 12 frequently advertised unhealthy foods/drinks. Consumption of these foods/drinks was dichotomized (less weekly, weekly or more) and summed (1 point for each item consumed weekly or more) to give cumulative consumption scores.

RESULTS

After adjusting for age and socioeconomic status, there was strong evidence of an increase in unhealthy food score (P < 0.001), drink score (P = 0.002) and food/drink combined score (P < 0.001), with increasing commercial television viewing.

CONCLUSIONS

The link between television viewing and poor diet was strongest for children who watched the most commercial television, and those who were actually exposed to advertisements embedded within programs. This association between advertisement exposure and poor diet emphasizes the need for public policy intervention to reduce children's food advertising exposures.

The use of granulocyte colony-stimulating factors in a Canadian outpatient setting

BACKGROUND

Data on real-life utilization of granulocyte colony-stimulating factors (g-csfs) in Canada are limited. The objective of the present study was to describe the reasons for, and the patterns of, g-csf use in selected outpatient oncology clinics in Ontario and Quebec.

METHODS

In a retrospective longitudinal cohort study, a review of medical records from 9 Canadian oncology clinics identified patients being prescribed filgrastim (fil) and pegfilgrastim (peg). Patient characteristics, reasons for g-csf use, and treatment patterns were descriptively analyzed.

RESULTS

Medical records of 395 patients initiating g-csf therapy between January 2008 and January 2009 were included. Of this population, 80% were women, and breast cancer was the predominant diagnosis (59%). The most commonly prescribed g-csf was fil (56% in Ontario and 98% in Quebec). The most frequent reason for g-csf use was primary prophylaxis (42% for both fil and peg), followed by secondary prophylaxis (37% fil, 41% peg). Those proportions varied by tumour type and chemotherapy regimen. Delayed g-csf administration (more than 1 day after the end of chemotherapy) was frequently observed for fil, but rarely reported for peg, and that finding was consistent across tumours and concurrent chemotherapy regimens.

CONCLUSIONS

The use of g-csf varies with the malignancy type and the provincial health care setting. The most commonly prescribed g-csf agent was fil, and most first g-csf prescriptions were for primary prophylaxis. Delays were frequently observed for patients receiving fil, but were rarely reported for those receiving peg.

Interactions of protamine with the marine bacterium, Pseudoalteromonas sp. NCIMB 2021

Pseudoalteromonas sp. NCIMB 2021 (NCIMB 2021) was grown in synthetic seawater (SSW) containing pyruvate, in the presence (SSW(++) ) and absence (SSW(-) ) of divalent cations. Cultures contained single cells. Addition of the cationic antibacterial peptide (CAP), protamine, did not inhibit, but rather increased, the growth of NCIMB 2021 in SSW(++) and caused the bacteria to grow in chains. Bacterial growth was assessed using turbidity, cell counts and the sodium salt of resazurin. In SSW(-) , NCIMB 2021 was no longer resistant to protamine. The minimum inhibitory concentration (MIC) was 5 mg ml(-1) .

SIGNIFICANCE AND IMPACT OF THE STUDY

Protamine is a cationic antimicrobial peptide (CAP), which is active against a variety of bacteria. This is the first in-depth study of the interaction of protamine with a marine bacterium, Pseudoalteromonas sp. NCIMB 2021. Our results show that protamine is only active in seawater in the absence of divalent cations. In the presence of the divalent cations, Mg(2+) and Ca(2+) , protamine enhances the growth of Pseudoalteromonas sp. NCIMB 2021 and produces chains rather than individual cells. These are important considerations when deciding on applications for protamine and in terms of understanding its mechanism of action.

Misreporting of energy intake in the 2007 Australian Children's Survey: differences in the reporting of food types between plausible, under- and over-reporters of energy intake

BACKGROUND

Misreporting is common when collecting dietary intake data, although relatively little is known about the types of foods misreported among children. The present study aimed to identify differences in the reporting of food types between plausible and misreporters of energy intake in a national nutrition survey of Australian children.

METHODS

Dietary data were collected using a 24-h recall from 4826 children aged 2-16 years who were participating in the 2007 Australian National Children's Nutrition and Physical Activity Survey. Misreporters of energy intake were classified using the Goldberg criteria. Differences in the reporting of a range of food types were examined between plausible, under- and over-reporters.

RESULTS

Compared with plausible reporters, under-reporters reported less frequent consumption and smaller quantities of consumption of both core and noncore foods. Older children (self-report) under-reported a larger selection of noncore foods than younger children (parental report). Over-reporters reported similar percentages of consumption of many core and noncore foods, with some exceptions. The quantities consumed by over-reporters were generally much larger and this was evident in younger and older children. Compared with plausible reporters, under-reporters had significantly higher intakes of protein and starch but lower intakes of sugar and fat, as percentage energy, than plausible reporters, whereas over-reporters had higher fat and lower carbohydrate intakes.

CONCLUSIONS

Differences in the reporting of food types were common between plausible, under- and over-reporters of energy intake by children (or their parents) and were not restricted to noncore foods.

Shifting curves? Trends in thinness and obesity among Australian youth, 1985 to 2010

OBJECTIVE

To describe 25-year trends in the prevalence of ≤Grade 2 thinness and obesity among Australian children by sex, age and socioeconomic (SES) background.

METHODS

Cross-sectional surveys of New South Wales school-aged children aged 6.0-16.9 years conducted in 1985-1997-2004-2010 (n = 19 434). Height/weight were measured, and thinness and obesity were defined by international standards. SES was derived from children's residential postcode using the Australian Bureau of Statistics' Index of Relative Socioeconomic Disadvantage, most proximal to the survey year.

RESULTS

Since 1985, the prevalence of thinness has not varied by survey year. Age was not associated with thinness; however, thinness was lower among middle SES boys, compared with high SES (OR: 0.45, 95%CI: 0.21, 0.97). The prevalence of obesity trebled between 1985 and 1997 (1.7% vs. 5.1% P = 0.000); however, since 1997, obesity prevalence has not significantly changed. Since 1997, obesity was higher among younger compared with older girls (OR: 2.11, 95%CI: 1.48, 3.00) and SES was inversely associated with obesity in boys (OR: 2.05, 95%CI: 1.44, 2.92) and girls (OR: 1.86, 95%CI: 1.27, 2.74).

CONCLUSIONS

The apparent plateau in child obesity is a welcome finding; however, the SES gradients are of concern. If the obesity stabilization is associated with the impact of multiple lifestyle behavioural interventions, the findings suggest obesity programmes have done 'no harm', but potentially the dose/delivery of interventions has not been sufficient or appropriate to reduce child obesity levels.

A synthesis of existing systematic reviews and meta-analyses of school-based behavioural interventions for controlling and preventing obesity

Schools are an attractive and popular setting for implementing interventions for children. There is a growing body of empirical research exploring the efficacy of school-based obesity prevention programs. While there have been several reviews on the topic, findings remain mixed. To examine the quality of evidence and compare the findings from existing systematic reviews and meta-analyses of school-based programs in the prevention and control of childhood obesity. This paper systematically appraises the methodology and conclusions of literature reviews examining the effectiveness of school-based obesity interventions published in English in peer-reviewed journals between January 1990 and October 2010. Eight reviews were examined, three meta-analyses and five systematic reviews. All of the reviews recognized that studies were heterogeneous in design, participants, intervention and outcomes. Intervention components in the school setting associated with a significant reduction of weight in children included long-term interventions with combined diet and physical activity and a family component. Several reviews also found gender differences in response to interventions. Of the eight reviews, five were deemed of high quality and yet limited evidence was found on which to base recommendations. As no single intervention will fit all schools and populations, further high-quality research needs to focus on identifying specific program characteristics predictive of success.

Best practice principles for community-based obesity prevention: development, content and application

Best practice in obesity prevention has generally been defined in terms of 'what' needs to be done while neglecting 'how'. A multifaceted definition of best practice, which combines available evidence on what actions to take, with an established process for interpreting this information in a specific community context, provides a more appropriate basis for defining the principles of best practice in community-based obesity prevention. Based on analysis of a range of literature, a preliminary set of principles was drafted and progressively revised through further analyses of published literature and a series of consultations. The framework for best practice principles comprises: community engagement, programme design and planning, evaluation, implementation and sustainability, and governance. Specific principles were formulated within this framework. While many principles were generic, distinctive features of obesity prevention were also covered. The engagement of end-users influenced the design of the formatting of the outputs, which represent three levels of knowledge transfer: detailed evidence summaries, guiding questions for programme planners and a briefer set of questions for simpler communication purposes. The best practice principles provide a valuable mechanism for the translation of existing evidence and experience into the decision-making processes for planning, implementing and evaluating the complex community-based interventions needed for successful obesity prevention.

Does leisure time physical activity protect against shoulder pain at work?

BACKGROUND

Shoulder pain is a common problem that can impact on work. Leisure time physical activity (LTPA) has the potential to reduce the impact of shoulder pain through its physiological, psychological and social benefits.

AIMS

To determine whether LTPA reduces the prevalence of shoulder pain in a working population.

METHODS

Participants were selected from a longitudinal population-based cohort study, the North West Adelaide Health Study. Information was gathered by questionnaire on LTPA, smoking, depression and socio-economic factors. Body mass index was measured in a clinic setting. Occupational physical activity (OPA) estimated by job title and shoulder pain was measured using the Shoulder Pain and Disability Index. Workers with and without shoulder pain were compared using logistic regression analysis.

RESULTS

Of the 1502 working participants, 16% reported having current shoulder pain. Shoulder pain was associated with older age (OR 1.98, 95% CI: 1.31-2.99) (age >50 years), smoking (OR 1.44, CI: 1.02-2.04), secondary-level educational attainment (OR 1.68, 95% CI: 1.07-2.65), high body mass index (BMI) (OR 1.54, 95% CI: 1.14-2.08) and depression (OR 2.42, 95% CI: 1.60-3.64). There was no effect of LTPA on shoulder pain.

CONCLUSIONS

In this community-based cohort, there was no statistically significant association seen between LTPA, OPA and shoulder pain. There was, however, an association between smoking, BMI, secondary-level education, depression and shoulder pain. These modifiable factors may be better targets for preventive efforts than LTPA to reduce the risk of shoulder pain.

SEMINARS IN PRACTICAL MANAGEMENT: “Riding the Tiger”: lessons from a health promotion activity aimed at reducing the use of alcohol by youth

This paper outlines a health promotion activity entitled "Riding the Tiger". "Riding the Tiger" aims to reduce binge drinking among youth and is an applicable intervention for both rural and urban areas. The paper aims to provide health care workers wishing to reduce the binge drinking of youth with a practical guide.

Providing care to the elderly with depression: the views of aged care staff

The purpose of this paper was to scope the views of care staff working in an aged care setting in an effort to understand the issues these staff face in the delivery of care to the elderly with depression. Seventeen care staff working in metropolitan, regional and rural areas of Queensland participated in one-on-one interviews in order to elicit their views on the identification of depression in the elderly and the care processes staff employed to manage depression. Interview notes were taken, reviewed, transcribed and analysed using content analysis. Discussion with participants revealed five themes regarding the management of depression in both community and residential aged care settings. These included: the extent to which depression is an issue for clients and residents; staff understanding of depression and the ability to recognize when a client or resident is depressed; discussing depression with general practitioner's and other healthcare professionals; processes and procedures for treating and addressing depression; and education and training on depression for staff. The findings revealed that care staff need greater education and training about depression and targeted strategies for its identification and management.

Age, period and birth cohort effects on prevalence of overweight and obesity in Australian adults from 1990 to 2000

OBJECTIVE

To assess the individual contributions of age, period and birth cohort to prevalence of overweight and obesity in the Australian population during 1990 to 2000.

DESIGN

Age-period-cohort Poisson regression modelling of data from National Health Surveys conducted in Australia in 1990, 1995 and 2000.

SUBJECTS

Adults aged 20 years and over. Weightings were applied to account for differences in sampling and participation rates so that the sample is representative of the entire Australian adult population.

METHODS

Twelve age groups, based on 5-year intervals from 20 to 24 years to greater than 75 years, three survey periods and 14 cohorts, also based on 5-year intervals from pre-1915 up to 1976-1980, were used in the analysis. The data were age-standardized to the 2000 population and body mass index (BMI) was calculated. Log-linear models, for the prevalence rates of overall overweight (BMI > or =25) and of obesity (BMI > or =30) were fitted to the data.

RESULTS

Age (P<0.001), period (P<0.001) and cohort (P=0.002) all showed significant independent effects on prevalence of overall overweight in the Australian population such that prevalence rises with increasing age, recency of period and cohorts born since 1960. Age (P<0.001) and period (P<0.001) demonstrated strong effects on prevalence of obesity but birth cohort (P=0.07) was not significant. The effects were similar for men and women except that the overall effect of birth cohort on overall overweight was significant in women (P<0.05) but not men (P=0.09).

CONCLUSION

The prevalence of overweight and obesity in Australian adults continued to rise during the 1990s. The obesogenic environment seems to have worsened and more recently born cohorts may be at increased risk of overweight.
