Blenderized food tube feeding in very young pediatric patients with special healthcare needs

BACKGROUND

Up to 85% of children with severe developmental disabilities have feeding disorders and require enteral tube feeding. Many caregivers desire blenderized tube feeding (BTF) instead of commercial formula (CF) for their child, citing a desire for a more physiologic feeding, to reduce gastrointestinal (GI) symptoms and/or promote oral intake.

METHODS

In this retrospective, single-center study, medical records (n = 34) of very young children (aged ≤36 months) with severe developmental disabilities were reviewed. Comparisons of growth parameters, GI symptoms, oral feeding, and GI medication use were made between the initial introduction of BTF and again at the last patient encounter when the children aged out of the program.

RESULTS

Of the 34 charts reviewed (16 male and 18 female patients), comparisons between baseline BTF introduction and the last patient encounter indicated reductions in adverse GI symptoms, significant GI medication reduction (P = 0.000), increased oral food intake, and nonsignificant improvements in growth parameters. These positive outcomes were realized whether children received full or partial BTF or type of BTF formulation.

CONCLUSION

Consistent with similar research studies, transitioning very young children with significant special healthcare needs from CF to BTF resulted in improvement in GI symptoms, reduced need for GI medications, supported growth goals, and contributed to improved oral feeding.

Low risk for microbial contamination of syringe and tube feeding bag surfaces after multiple reuses with home blenderized tube feeding

BACKGROUND

Guidelines for the reuse of enteral tube feeding (ETF) equipment guidelines are limited to manufacturer recommendations. ETF equipment reuse studies are needed as the enteral population has increased, along with blenderized tube feeding (BTF).

METHODS

This experiment tested microbial contamination of a reusable gravity feeding bag and syringe after 15 BTF reuses and cleanings. Eight bags and syringes were filled with the BTF, held at room temperature for 20 min, and then emptied, washed, and air dried. After the last air drying, the inner surfaces of the bag and syringe were swabbed, and aerobic microbial counts were performed using serial dilutions and plate counts.

RESULTS

The microbial counts for all syringes and six bags were <1 colony-forming unit (CFU)/cm² ; one bag was <5 CFU/cm² and one bag was 12.5 CFU/cm² . No legal guidelines for surface cleanliness exist for the food sector. Several studies propose a safe microbial level to be <2.5 CFU/cm² , and the European Commission recommended <10 CFU/cm² . Based on these proposed guidelines, microbial counts of all syringes and seven bags were within the proposed guidelines, except for one bag just above 10 CFU/cm² .

CONCLUSION

The feeding bag used in this study may be used multiple times for BTF with a reduced risk of microbial contamination when manufacturer's cleaning guidelines are followed. Although bolus tube feeding is an off-label use for syringes, they are frequently used for BTF, and in this study the cleaning after 15 uses over 5 days was effective to reduce microbial counts.

Blenderized food tube feeding in patients with head and neck cancer

Background

Patients with headand neck cancer (HNC) are at high risk for malnutrition before and during chemoradiation treatment. Many will also require tube feeding to address declines in energy intake, weight, and quality of life (QOL) caused by the impact of treatment on gastrointestinal (GI) symptoms. Blenderized tube feeding (BTF) may ameliorate these adverse conditions.

Methods

In this open‐label, prospective pilot study, 30 patients with HNC who required feeding tube placement were recruited to switch from standard commercial formula after 2 weeks to a commercially prepared BTF formula. Weight, body mass index (BMI), GI symptoms, and QOL scores were tracked for 6 weeks from the first week of feeding tube placement.

Results

Of the 16 patients who completed the 6‐week assessment period, weights and BMI scores for 15 patients trended upward. For most patients, QOL and oral intake increased and GI symptoms decreased over the 6‐week period, particularly during weeks 3 and 4, when the impact of treatment is particularly exacting on patients with HNC.

Conclusion

BTF effectively mitigated weight loss, GI symptoms, QOL scores, and total energy intake in this group of patients with HNC who received tube feeding for 6 weeks.

Cardiopulmonary Exercise Testing in Oesophagogastric Surgery: a Systematic Review

BACKGROUND

Cardiopulmonary exercise testing (CPX) can objectively measure fitness and oxygen uptake at anaerobic threshold. The relationship between fitness and postoperative outcomes after upper gastro-intestinal surgery is unclear. The aim of the present review is to assess the prognostic ability of CPX in predicting postoperative outcome associated with oesophagogastric surgery.

METHODS

Relevant studies were identified through a systematic search of EMBASE, Medline, CINAHL, Cochrane Library, and Web of Science to July 2019. The eligibility criteria for studies included prognostic studies of upper gastro-intestinal surgery among adult populations using a preoperative CPX and measurement of postoperative outcome (mortality or morbidity or length of stay). Risk of bias was assessed using the QUIPS Quality in Prognostic Studies validated tool.

RESULTS

Thirteen papers with a total of 1735 participants were included in data extraction. A total of 7 studies examined the association between CPX variables and postoperative mortality. Patients undergoing gastro-intestinal surgery with lower anaerobic threshold values were found to have an increased risk of postoperative mortality. Similarly, a lower rate of oxygen consumption was found to be associated with higher mortality. There was conflicting evidence regarding the association between CPX variables and postoperative morbidity. The evidence did not demonstrate any association between preoperative CPX variables and hospital length of stay.

CONCLUSION

Studies report an association between CPX variables and postoperative mortality; however, there is conflicting evidence regarding the association between CPX variables and postoperative morbidity.

Kicking the habit - how can we improve the routine care for patients who are well controlled living with HIV?

The objective is to improve and standardise HIV care for people with well-controlled HIV across the region by comparing monitoring within services to UK audit standards. This was a retrospective case note review from 01.01.2018 to 31.12.2018. The standards were sourced from the British HIV Association (BHIVA), the British Association for Sexual Health and HIV (BASHH), and the Faculty of Sexual and Reproductive Health (FSRH). Six services took part with 228 patient records being audited. Two of the 5 national standards were met (blood pressure and medication review). From the 8 areas previously audited in 2014, 6 showed improvements (offer of STI screen, medication review, urinalysis, mental health screen and influenza vaccination documentation). Cardiovascular disease (CVD) risk and transmission risk had poorer documented outcomes. In addition, nearly one-third of patients were over-tested regarding their CD4 count. We recommend that letters should include a standard message about U = U (undetectable = untransmittable) and vaccinations; CVD risk and FRAX should be calculated once a year in place of a routine letter; an annual summary letter should be written in place of a letter after each clinic visit; and consistent use of a proforma, with BHIVA/BASHH/FSRH recommendations on monitoring included.

B-50 Frequency of Sports-Related Concussion in Athletes with Neurodevelopmental Conditions

Objective

Research demonstrates that athletes with neurodevelopmental diagnoses may have a higher frequency of lifetime concussions (Iverson et al., 2016; Alosco, Fedor & Gunstad, 2014) possibly due to underlying attention, processing speed, or reaction time difficulties. The present study investigates concussion history and sports-related concussions between athletes with and without a history of neurodevelopmental disorders in a longitudinal, state-wide sample.

Method

Participants included 39,586 high school athletes (Mage = 15.18; 56.2% males) who were assessed pre and post-concussion with ImPACT between 2008 and 2016. There were 36,880 athletes (55.1% males) who did not report neurodevelopmental disorders and served as the control group and 2,706 athletes (71.4% males) in the clinical group who self-reported diagnosis of ADHD (55.6%), Learning Disability (LD;13.6%), Autism (3.2%), ADHD+LD (4.5%), and athletes in special education but no reported diagnosis (SpEd; 22%). Concussion frequency in each group was analyzed using chi-square analysis.

Results

Athletes were more likely to report prior concussions if they had a self-reported neurodevelopmental diagnosis (17%) compared to the control group (9%, χ2(1) = 112.11, p < .001). Odds ratios indicated that athletes with neurodevelopmental conditions were 1.43 times more likely to have a sports-related concussion.

Conclusions

Consistent with past research, results indicate that neurodevelopmental conditions are associated with greater lifetime risk of concussion, including sport-related concussions. Future studies may expand this research by examining underlaying causes of this increased risk in order to develop specific interventions to help reduce rates of concussion for this population.

B-55 Performance of ImPACT Validity Indices for Athletes with Neurodevelopmental Disorders

Objective

Research demonstrates neurodevelopmental diagnoses may increase likelihood of failing scores on ImPACT embedded validity indicators that flag questionable effort. New criteria have been proposed to enhance sensitivity of these indicators although their utility in athletes with neurodevelopmental diagnosis have not been thoroughly examined. This study investigates the effect of neurodevelopmental history on frequency of invalid performance on the standard and three proposed validity indicators.

Methods

Participants included 41,214 high school athletes (Mage = 15.1; 44.2% female; Meducation = 9.1) who completed baseline ImPACT testing. Athletes included these groups: ADHD (3.7%), Learning Disability (LD; 1.5%), Autism (0.2%), ADHD+LD (0.6%), Autism+ADHD/LD (0.1%), athletes with special education history but no diagnosis reported (SpEd; 2.8%), and healthy athletes (91.1%). Odds ratios were calculated to determine differences in invalid performance by both standard and proposed cutoffs.

Results

Neurodevelopmental disorder was associated with increased invalid performance using standard and proposed cutoffs with odds ratios ranging from 1.32 to 3.25. Invalid performance differed significantly across groups for both standard and two sets of proposed criteria (chi square p < .00001). For standard cutoffs, athletes with ADHD, LD, and ADHD/LD were significantly more likely than healthy athletes to have invalid performance. This pattern remained similar across the two sets of proposed criteria.

Conclusions

Results indicate increased incidence of invalid ImPACT performance based on standard and proposed validity indicators in athletes who self-report neurodevelopmental disorders. Findings indicate current and proposed cutoffs may not accurately capture low effort for neurodevelopmental populations. Future research should examine utility of separate cutoff criteria and expanded norms for athletes with neurodevelopmental history.

Measuring the impact of oesophagectomy on physical functioning and physical activity participation: a prospective study

BACKGROUND

Oesophagectomy remains the only curative intervention for oesophageal cancer, with defined nutritional and health-related quality of life (HR-QOL) consequences. It follows therefore that there is a significant risk of decline in physical wellbeing with oesophagectomy however this has been inadequately quantified. This study prospectively examines change in physical functioning and habitual physical activity participation, from pre-surgery through 6-months post-oesophagectomy.

METHODS

Patients scheduled for oesophagectomy with curative intent were recruited. Key domains of physical functioning including exercise tolerance (six-minute walk test (6MWT)) and muscle strength (hand-grip strength), and habitual physical activity participation, including sedentary behaviour (accelerometry) were measured pre-surgery (T0) and repeated at 1-month (T1) and 6-months (T2) post-surgery. HR-QOL was measured using the EORTC-QOL C30.

RESULTS

Thirty-six participants were studied (mean age 62.4 (8.8) years, n = 26 male, n = 26 transthoracic oesophagectomy). Mean 6MWT distance decreased significantly from T0 to T1 (p = 0.006) and returned to T0 levels between T1 and T2 (p < 0.001). Percentage time spent sedentary increased throughout recovery (p < 0.001) and remained significantly higher at T2 in comparison to T0 (p = 0.003). In contrast, percentage time spent engaged in either light or moderate-to-vigorous intensity activity, all reduced significantly (p < 0.001 for both) and remained significantly lower at T2 in comparison to T0 (p = 0.009 and p = 0.01 respectively). Patients reported deficits in multiple domains of HR-QOL during recovery including global health status (p = 0.04), physical functioning (p < 0.001) and role functioning (p < 0.001). Role functioning remained a clinically important 33-points lower than pre-operative values at T2.

CONCLUSION

Habitual physical activity participation remains significantly impaired at 6-months post-oesophagectomy. Physical activity is a measurable and modifiable target for physical rehabilitation, which is closely aligned with patient-reported deficits in role functioning. Rehabilitation aimed at optimising physical health in oesophageal cancer survivorship is warranted.

Plagiarism in nursing education and the ethical implications in practice

An important ethical issue in nursing education continues to be the evolving concerns of plagiarism. Plagiarism presents itself in a variety of different circumstances, which can influence both the classroom and the clinical environment. Nursing educators often struggle with how to handle the impact of plagiarism. This article aims to provide nursing educators with some practical learning strategies and recommendations to address present day plagiarism issues.

Exercise Rehabilitation Services Provided by Physiotherapy Departments in Cancer Care in Ireland

Aims This study aimed to identify the physiotherapy exercise rehabilitation services available to patients with cancer in Ireland and to identify barriers to the provision of services. Methods Physiotherapy department managers in specialised cancer centres, public and private hospitals and palliative care settings were surveyed to establish the availability of exercise rehabilitation services for patients with cancer. Results Of 40 managers contacted, 24 responded providing information about 26 services. Ten services employed a dedicated oncology physiotherapist. Exercise classes were offered to patients with cancer by five services, primarily within the palliative care setting. In the 17 hospitals which provided surgery, ten provided oncology specific post-operative exercise rehabilitation and one offered a prehabilitation programme. Limited human and physical resources and absence of established physiotherapy pathways were cited barriers to service provision. Conclusion Exercise rehabilitation is not an element of standard care for patients with cancer in Ireland.

The views of patients with metastatic prostate cancer towards physical activity: a qualitative exploration

PURPOSE

Patients with metastatic cancer can experience debilitating symptoms, which may influence attitudes towards and engagement in physical activity. This study aimed to examine the attitudes of patients living with metastatic prostate cancer towards physical activity.

MATERIALS AND METHODS

Semi-structured interviews were completed with male patients living with metastatic prostate cancer. Interviews included eight questions related to patients' attitudes towards physical activity. Content analysis was conducted on the transcribed interview data. Twenty men with metastatic prostate cancer (mean age 71 ± 8.5 years; body mass index 30.19 ± 5.37 kg/cm²) and associated bone metastases (55% with > 2 regions affected) participated in the study.

RESULTS

Men's views towards physical activity were coded into the following major themes: (1) barriers to physical activity, (2) benefits of physical activity, (3) a reduction in physical activity levels post diagnosis and (4) social support for physical activity. Symptoms of metastatic prostate cancer and treatment side effects including pain and fatigue negatively influenced activity participation. In addition, many generic barriers to physical activity were described such as bad weather and a lack of suitable facilities for exercising in rural areas.

CONCLUSION

Men living with metastatic prostate cancer have unique needs regarding physical activity related to symptoms of both their cancer and cancer treatment. There is a need to increase prompts that encourage those with metastatic prostate cancer to maintain/increase physical activity levels post diagnosis. Given the individualised needs of this patient group, referral to a cancer exercise specialist should be considered for prescription of tailored physical activity programmes.

Reduced fitness and physical functioning are long-term sequelae after curative treatment for esophageal cancer: a matched control study

Reduced physical functioning is common following resections for esophageal cancer; however, objective data on physical performance outcomes in this cohort are rare. The aim of this study was to assess the physical performance and health related quality of life (HRQOL) of disease free survivors and compare findings in a case matched noncancer control group. Twenty-five males (mean (±SD) aged 63 (±6) years) who were over 6 months postesophagectomy and disease-free were compared with 25 controls (60 ± 6 years). Physical functioning was assessed through hand grip strength (dynamometry), exercise capacity (incremental shuttle walk test), physical activity levels (RT3 accelerometer), and body composition (bio-electrical impedance analysis). Health-related quality of life was measured using the EORTC QLQ-C30 questionnaire. Esophageal cancer survivors demonstrated significantly lower fitness (P < 0.001) and time spent in moderate (P < 0.001) and vigorous (P < 0.001) intensity physical activity compared with controls. Global health status and quality of life were similar in both groups (P = 0.245); however, physical and role functioning domains were lower in the cancer survivors (P < 0.001, and P = 0.001, respectively). These data show that disease-free survivors of curative esophageal cancer treatment demonstrate a significant compromise in physical functioning compared with controls, thus highlighting the multiple, complex rehabilitative needs of this cohort.

The sedentary profile of primary care patients

Background

Primary care is one of the key environments in which to target public health and sedentary behaviours are increasing being linked to several adverse health outcomes. The aim of this study was to determine the prevalence and correlates of sedentary behaviour in an adult primary care population.

Methods

The International Physical Activity Questionnaire was used to collect data on the weekday sitting of participants. Stratified random sampling based on urban/rural location and deprivation was used to identify three primary care centres from which the sample was drawn.

Results

Data were collected from 885 participants (96.7% response rate) of whom 64% (n = 565) were female and 36% (n = 320) were male. The mean age was 42 (SD 14.2). Overall 48% (n = 418) of participants sat for >4 h daily with a median sitting time of 240 min (IQR 150-480). Attendance at the urban non-deprived primary care centre (B = 0.237, P < 0.001), male gender (B = 0.284, P < 0.001), overweight/obesity (B = 0.081, P = 0.048) and having a disability or injury limiting physical activity (B = 0.093, P = 0.028) were associated with higher sitting times.

Conclusion

This study established the factors that influence sedentary behaviours in the primary care population which can help inform the development and targeting of promotional strategies.

Abstract P3-09-02: Unhealthy lifestyle patterns are prevalent in unaffected BRCA mutation carriers & are associated with increased oxidative stress and telomere length alterations

The lifetime-risk of breast-cancer is greatly increased in women carrying a deleterious mutation in the BRCA1 or BRCA2 genes. Recently, there has been increased penetrance of BRCA1 and BRCA2 mutations which may be due to lifestyle influences.

There is a need to identify approaches to reduce the penetrance of BRCA 1/2 mutations. Understanding how modifiable lifestyle-factors affect cancer-risk in BRCA-mutation carriers may have implications for risk-reduction in this group. At the molecular level, oxidative-stress and telomere dysfunction are early events in cancer development and these processes may be considered surrogate markers of cancer-risk. It has been reported that BRCA-mutation carriers are more susceptible to these pro-carcinogenic processes that non-carriers.

The aim of this pilot study was to objectively measure lifestyle factors in unaffected BRCA-mutation carriers and to assess the impact of these lifestyle-factors on oxidative-stress profiles and telomere length.

Participants (n=75) were recruited from breast-cancer family-risk clinics and cancer-genetics clinics. Body-composition (BMI, waist-circumference), metabolic profiles and physical-activity (triaxial accelerometry) were measured for each participant. Serum levels of the oxidative-stress markers 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-DG) and 4-hydroxynonenal (4-HNE) were measured in a subset of participants (n=30) by ELISA. Telomere length was measured in a subset of participants (n=30) by quantitative PCR (qPCR).

Participants demonstrated poor adherence to physical-activity guidelines with 94% not reaching physical-activity levels recommended by the American College of Sports Medicine. The majority of participants were overweight (39%) or obese (32%) with 73% exhibiting abdominal obesity. 21% of participants had the metabolic syndrome (MetS) at the time of study enrolment with the majority of participants (80%) presenting with at least one feature of the MetS. Circulating levels of 8-oxo-DG did not appear to be affected by body composition or MetS status, however, serum levels of the lipid peroxidation marker 4-HNE were significantly higher in participants with the MetS (p &lt; 0.0001). Correlation of serum 4-HNE levels with individual features of the MetS and related parameters revealed significant direct correlations with waist circumference (p = 0.02), number of features of MetS (p = 0.0007), insulin (p = 0.02) insulin resistance score (HOMA-IR) (p = 0.01), HBA1c (p = 0.006), glucose (p = 0.048) and triglycerides (p &lt;0.0001). Age-adjusted telomere length was not influenced by anthropometric measurements or MetS status in this group. Moderate physical activity levels were inversely associated with age-adjusted telomere length; particularly, among post-menopausal participants (p =0.009).

This work has provided compelling evidence that in this cohort of BRCA-mutation carriers, unhealthy lifestyle-patterns are prevalent. In addition, these results suggest that the potential may exist to modify pro-carcinogenic processes in this cohort by modifying physical activity levels and targeting the metabolic syndrome and its component features lifestyle interventions and/or medication.The lifetime-risk of breast-cancer is greatly increased in women carrying a deleterious mutation in the BRCA1 or BRCA2 genes.

The physiotherapist and the esophageal cancer patient: from prehabilitation to rehabilitation

Esophageal cancer is a serious malignancy often treated with multimodal interventions and complex surgical resection. As treatment moves to centers of excellence with emphasis on enhanced recovery approaches, the role of the physiotherapist has expanded. The aim of this review is to discuss the rationale behind both the evolving prehabilitative role of the physiotherapist and more established postoperative interventions for patients with esophageal cancer. While a weak association between preoperative cardiopulmonary fitness and post-esophagectomy outcome is reported, cardiotoxicity during neoadjuvant chemotherapy and/or radiotherapy may heighten postoperative risk. Preliminary studies suggest that prehabilitative inspiratory muscle training may improve postoperative outcome. Weight and muscle loss are a recognized sequelae of esophageal cancer and the functional consequences of this should be assessed. Postoperative physiotherapy priorities include effective airway clearance and early mobilization. The benefits of respiratory physiotherapy post-esophagectomy are described by a small number of studies, however, practice increasingly recognizes the importance of early mobilization as a key component of postoperative recovery. The benefits of exercise training in patients with contraindications to mobilization remain to be explored. While there is a strong basis for tailored physiotherapy interventions in the management of patients with esophageal cancer, this review highlights the need for studies to inform prehabilitative and postoperative interventions.

Obesity in the HIV-infected population in Northeast England: a particular issue in Black-African women

People living with HIV are surviving longer on successful antiretroviral therapy and obesity rates are increasing. We sought to determine the prevalence of being overweight or obese in a regional population of people living with HIV and to explore the demographic and clinical characteristics associated with obesity or being overweight. Data on patients attending three Northeast England clinics were collected including body mass index and demographics. The prevalence of being overweight (body mass index ≥ 25 kg/m²) or obese (body mass index ≥ 30 kg/m²) was determined and compared with regional population data. Associations between being overweight or obese and demographic and other data were further explored using logistic regression models. In 560 patients studied (median age 45 years, 26% Black-African and 69% male), 65% were overweight/obese and 26% obese, which is similar to the local population. However, 83% and 48% of Black-African women were overweight/obese or obese, respectively, with 11% being morbidly obese (body mass index > 40 kg/m²). In the multivariate analyses, the only factors significantly associated with obesity were Black-African race (adjusted odds ratio 2.78, 95% confidence interval 1.60-4.85) and type 2 diabetes (adjusted odds ratio 4.23, 95% confidence interval 1.81-9.91). Levels of obesity and overweight in people living with HIV are now comparable to the levels in the local population of Northeast England; however, the prevalence is significantly higher in Black-African women. Given the additional risk factors for cardiovascular disease inherent in people living with HIV, better strategies to prevent, identify and manage obesity in this population are needed.

Audit of gonorrhoea test of cure at the genitourinary medicine department in Newcastle upon Tyne, UK

The aim of the audit was to assess the need for a microbiological test of cure for gonorrhoea when a sensitive antibiotic has been used. All cases of gonorrhoea attending our clinic in 2001 were reviewed. One hundred and seventy-three cases were diagnosed, 137 men and 36 women. Of the 126 cases where tests of cure were taken, none were positive from an infective site when a sensitive antibiotic was used. Cases of gonorrhoea from year 2000 were then analysed for test of cure. Of 125 tests of cure again none were positive. These results question the need for routine tests of cure which current national guidelines state are usually performed in UK practice. The implications of abandoning a test of cure visit are discussed.

Location and deprivation are important influencers of physical activity in primary care populations

OBJECTIVES

To investigate the physical activity of adults attending primary care services in the Republic of Ireland and to determine whether the location (urban/rural) and deprivation of the primary care centre influenced physical activity.

STUDY DESIGN

Cross sectional study.

METHODS

Stratified random sampling based on urban/rural location and deprivation was used to identify three primary care centres from a list of established primary care teams in the Leinster region. The International Physical Activity Questionnaire (IPAQ) was used to collate data on physical activity category (low/moderate/high), total weekly activity (MET-minutes/week) and weekly walking (MET-minutes/week) of participants.

RESULTS

Data from 885 participants with a median age of 39 years (IQR 31-53) were analysed. There were significant differences in physical activity between the primary care areas (P < 0.001). Rural mixed deprivation participants were the least active with almost 60% of this group (59.4%, n = 177) classified as inactive (535 median MET-minutes/week, IQR 132-1197). Urban deprived participants were the most active (low active 37.6%, n = 111, 975 median MET-minutes/week, IQR 445-1933). Upon adjustment for multiple factors, rural participants (OR = 2.81, 95% CI 1.97-4.01), urban non-deprived participants (OR = 1.61, 95% CI 1.08-2.39), females (OR = 1.66, 95% CI 1.23-2.23) and older adults (OR = 1.01, 95% CI 1.00-1.02) were more likely to be categorised as low active. Overall 47.2% (n = 418) of all participants were classified within the low physical activity category.

CONCLUSIONS

Significant disparities exist in the physical activity levels of primary care populations. This has important implications for the funding and planning of physical activity interventions.

The energy cost of playing active video games in children with obesity and children of a healthy weight

BACKGROUND

Increasing physical activity and reducing sedentary behaviour form a large part of the treatment of paediatric obesity. However, many children today spend prolonged periods of time playing sedentary video games. Active video games (AVGs) represent a novel and child friendly form of physical activity.

OBJECTIVES

To measure the energy cost of playing two AVGs in children with obesity and healthy age- and gender-matched children.

METHODS

The energy cost of gaming and heart rates achieved during gaming conditions were compared between groups.

RESULTS

AVG play can result in light-to-moderate intensity physical activity (2.7-5.4 metabolic equivalents). When corrected for fat-free mass those with obesity expended significantly less energy than healthy weight peers playing Nintendo Wii Fit Free Jogging (P = 0.017). No significant difference was seen between groups in the energy cost of playing Boxing.

CONCLUSION

Certain AVGs, particularly those that require lower limb movement, could be used to increase total energy expenditure, replace more sedentary activities, or achieve moderate intensity physical activity among children with obesity. There seems to be some differences in how children with obesity and children of a healthy weight play AVGs. This could result in those with obesity expending less energy than their lean peers during AVG play.

Preventing congenital syphilis - a regional audit of syphilis in pregnant women seen in Genitourinary Medicine services

Genitourinary case records of 42 pregnant women with syphilis were reviewed as part of a regional audit following the re-emergence of congenital syphilis in the north east of England. National standards, from the British Association of Sexual Health and HIV guidelines on managing syphilis in pregnancy, were met in the majority of cases with 69% being treated according to national guidance and all cases completing treatment. Locally developed standards on multidisciplinary working and communication were met less well, with particular issues regarding the documentation of pregnancy outcomes in GUM records and communication between specialities being highlighted. A regional good practice guide has been developed and implemented to address standards not met, reduce adverse outcomes and prevent future cases of congenital syphilis.

Feasibility and efficacy of a supervised exercise intervention in de-conditioned cancer survivors during the early survivorship phase: the PEACH trial

PURPOSE

This study aims to evaluate the feasibility and efficacy of an 8-week supervised exercise program in de-conditioned cancer survivors within 2-6 months of chemotherapy completion.

METHODS

Participants were randomly assigned to an 8-week, twice-weekly, supervised aerobic exercise training regime (n = 23) or a usual care group (n = 20). Feasibility was assessed by recruitment rate, program adherence and participant feedback. The primary outcome was aerobic fitness assessed by the Modified Bruce fitness test at baseline (0 weeks), post-intervention (8 weeks) and at 3-month follow-up. Secondary outcomes included physical activity, waist circumference, fatigue and quality of life.

RESULTS

The recruitment rate was 81 % and adherence to the supervised exercise was 78.3 %. Meaningful differences in aerobic fitness between the exercise and usual care groups at both the 8-week [mean 3.0 mL kg(-1) min(-1) (95 % CI -1.1-7.0)] and 3-month follow-up [2.1 mL kg(-1) min(-1) (-2.3-6.6)] were found, although these differences did not achieve statistical significance (p values >0.14). Self-reported physical activity increased in the exercise group (EG) compared to the usual care group at both 8-week (p = 0.01) and 3-month follow-up (p = 0.03) and significant differences in favour of the EG were found for physical well-being at both the 8-week (p = 0.03) and 3-month follow-up (p = 0.04). Improvements in fatigue (p = 0.01), total quality of life plus fatigue (p = 0.04), and a composite physical functioning score (p = 0.01) at the 3-month follow-up were also found.

CONCLUSION

The PEACH trial suggests that 8 weeks of supervised aerobic exercise training was feasible and may improve aerobic fitness, fatigue and quality of life in de-conditioned cancer survivors during the early survivorship phase.

IMPLICATIONS FOR CANCER SURVIVORS

Exercise interventions commenced in the early survivorship phase appear safe, feasible and may lead to improvements in QOL and fatigue.

The effect of aerobic exercise on metabolic and inflammatory markers in breast cancer survivors--a pilot study

PURPOSE

Physical activity is associated with a reduced risk of breast cancer development and recurrence. There are several hypothesised mechanisms for this including positive effects on metabolic and inflammatory biomarkers and favourable changes in anthropometric variables. This pilot study examined the effect of an 8-week aerobic exercise intervention on several of these outcomes, including body composition, the metabolic syndrome, C-reactive protein (CRP) and physical activity, in breast cancer survivors 2-6 months post-chemotherapy.

METHODS

Assessments were completed at baseline, at 8-weeks and 3-months post-intervention. Measures taken following a 12-h fast included body composition (bioimpedance analysis), metabolic syndrome (waist circumference, blood pressure, high-density lipoprotein cholesterol, triglycerides and fasting glucose), insulin resistance (homeostatic model assessment), CRP and physical activity (accelerometry and questionnaire). Participants were randomized to either an 8-week moderate-intensity aerobic exercise group or a usual-care control group. Analysis was completed using repeated-measures analysis of variance (ANOVA) (p = 0.05).

RESULTS

Twenty-six breast cancer survivors participated (mean (standard deviation) age 48.1 (8.8) years, exercise group; n = 16, control group; n = 10). At baseline, 13 participants were overweight, 6 were obese and 19 centrally obese. Intention-to-treat analysis revealed no significant differences between the exercise and control groups in any of the outcomes measures; however, analysis of those who adhered to >90 % of the supervised exercise class showed a significant decrease in waist circumference (p = 0.05) and a significant increase in subjectively reported "total weekly" (p = 0.005) activity.

CONCLUSION

While this 8-week aerobic exercise pilot intervention did not elicit significant improvements in biomarkers of breast cancer risk, there was some suggestion of improvements in waist circumference and subjectively measured physical activity in participants with >90 % adherence to the programme. A trial of longer duration and greater subject numbers is warranted.

Physical activity and cardiovascular disease risk factors in urban school children

Although the clinical signs of cardiovascular disease (CVD) are not evident until adulthood, many of the risk factors have their roots in early childhood. The aim of this study was to examine physical activity levels (PA) and the incidence of CVD risk factors in a small population (n=102) of primary school children in Dublin. Risk factors measured included overweight/obesity, blood lipids, blood pressure (BP), physical fitness and PA levels. Over a quarter of the group were overweight/obese (n = 29, 28%). Despite relatively good fitness levels, PA levels were low with less than half the group (n = 44, 46%) participating in the recommended 1 hour/day. Fewer girls reported spending > 1 hour/day at PA compared to boys (n = 14 v n = 30). Six children had elevated cholesterol levels and five children had higher than normal BP values. Sixteen children demonstrated clustering of CVD risk factors and in those who were inactive the risk was greater. Our data suggest that in children as young as 10 years significant risk factors already exist. Furthermore, the low level of PA in girls provides a target for health promotion programmes.
