Staff perspectives on poor mental health in secondary school students: an increasing problem handled with insufficient resources.

Introduction: An increasing number of schools are recognizing the importance of addressing students' mental health based on the association with educational outcomes and long-term health. The school organization and the members of the school staff play important but, in several ways, challenging roles in this work. The purpose of this study was to explore views of staff from schools and school health services on mental ill health among students and their own role in detecting and managing it. Methods: A qualitative study was conducted in a sparsely populated municipality in northern Sweden. In total, 40 participants from three secondary schools and the school health services participated either in focus groups or individual interviews. Participants were teachers, assistants, school nurses, school counselors and psychologists. Data were analyzed using thematic analysis. Results: The analysis revealed the main theme Student mental ill health: an increasing problem handled with insufficient resources and two subthemes, i.e., Uncertainty in interpreting students' signs of mental ill health and the need to clarify roles and establish a supportive organization. Conclusions: It was concluded that school staff were uncertain regarding how to interpret signs of mental ill health among students and required better knowledge and more resources to help students with mental ill health. A clearer organization and consensus regarding support for students with mental ill health were also necessary in light of the division of responsibilities between school staff and the school health services.

Co-occurrence of online and offline bullying and sexual harassment among youth in Sweden: Implications for studies on victimization and health a short communication.

Studies of co-occurrence of online and offline victimisation of bullying and sexual harassment and its associations to mental health outcomes among youth are scarce. To inform future study designs, the aim of this brief communication was to map co-occurrence of online and offline bullying and sexual harassment victimisation among adolescents. Data were collected in 2011 in nine schools in Northern Sweden, n = 1193 (boys = 566; girls = 627). Absolute and relative frequencies were calculated to find combinations of victimisation: one, two, three, or four forms. Reflecting a picture of the early days of online victimisation, in total fifty seven percent (57%) of adolescents were victimised. Single occurrence victimisation was 21.2% (offline sexual harassment was most common irrespective of gender), showing that most youths were victimised in a co-occurrence of two or more forms. Seven percent (7%) were victimised by all four forms of victimisation. Offline sexual harassment victimisation was present in the most common co-occurrences. Directions for future studies of victimisation and its associations to mental health outcomes are discussed.

Longitudinal Associations Between Energy Drink Consumption, Health, and Norm-Breaking Behavior Among Swedish Adolescents.

Objectives: To describe the intake of energy drinks (EDs) among a sample of Swedish adolescents while considering health-related variables, and to investigate the longitudinal associations between ED consumption, health, and norm-breaking behavior. Longitudinal studies on this topic are scarce. Methods: Questionnaire data were collected in the northern part of Sweden in 2010-2011 from 1,622 adolescents in grades 6-9. Analyses were performed using a chi-squared test and logistic regression. Results: Seventy-four percent of the boys and 54% of the girls had consumed EDs (P < 0.001). ED consumption was associated with variables related to low health, low support levels, and norm-breaking behavior. The associations were generally stronger among the girls and the boys who consumed EDs at least once a week. ED consumption was a predictor of worse health and norm-breaking behavior 1 year later. Adjusted odds ratios ranged from 1.53 (95% CI: 1.07, 2.20; school-related stress) to 4.88 (95% CI: 2.28, 10.43; gaming-related truancy). Conclusions: Health promotion activities benefit from a broad approach but could focus on girls who consume EDs and those boys with the highest consumption levels.

Perceived and Preferred Social Support in Patients Experiencing Weight Regain After Bariatric Surgery-a Qualitative Study.

PURPOSE: While bariatric surgery generally shows successful weight loss outcomes in patients with obesity, weight regain exists. The aim of this qualitative study was to improve understanding of how patients with substantial weight regain after bariatric surgery experienced the support from family, friends, and healthcare providers, and what kind of support they had preferred. MATERIALS AND METHODS: Qualitative data were collected from semi-structured interviews with 16 participants. Mean weight regain from surgery to interview was 36%. The transcribed interviews were analyzed with thematic analysis. RESULTS: Two main themes and seven sub-themes were formulated. The theme, A lonely struggle, illustrates patients' feelings of abandonment and struggle during weight regain due to lack of support or unfavorable treatment. Participants commonly blamed themselves for re-gaining weight, and shame made them reluctant to engage in social activities or seek medical care. The theme, Others as sources of compassion and control, covers what support they desired, as well as had perceived to be helpful. Exercising or eating healthy with others was appreciated and felt supportive. Pro-active healthcare support and access to dietitians, physiotherapists, and psychological support were desired. CONCLUSION: To optimize the effect of bariatric surgery, support may need to be individualized and lifelong. Since shame and self-blame in patients with weight regain may hinder seeking professional help, care providers may need to initiate follow-up visits. Empathetic and non-judgmental support, access to multidisciplinary healthcare team, as well as peer-support groups may be beneficial to counteract weight regain post-bariatric surgery.

On Time: A Qualitative Study of Swedish Students', Parents' and Teachers' Views on School Attendance, with a Focus on Tardiness.

Tardiness is a common problem in many schools. It can be understood as an individual risk for future problematic behavior leading to absenteeism, school dropout, exclusion and later health problems. Tardiness can also be examined in relation to a broader social-ecological perspective on health. The aim of this study was to analyze students', school staff's and parents' views on students' tardiness in two Swedish schools. A focus group interview design was used with 21 school personnel, 21 students in grade nine and two parents. The data were analyzed by using thematic content analysis. The results illustrated the main theme-It depends on…-regarding what will happen if a student arrives late to school lessons. This finding is further explained by the subthemes about teachers' signals and reactions and the responses from teachers and students. The conclusion showed the importance of organizing the school day more predictably for the students. Late arrival is a sign of shortcomings in a school organization. It is necessary to develop guidelines related to how to handle students' late arrival based on predictable viewpoints but even more so on how to promote students' sense of belonging and their interest in and motivation for going to school.

Overcoming Barriers: Adolescents' Experiences Using a Mobile Phone Dietary Assessment App.

BACKGROUND: The use of new technology has the potential to increase participation rates in dietary studies and improve the validity of collected dietary data. However, to evaluate the usability of developed dietary methods, qualitative studies of participants' experiences and perceptions are needed. OBJECTIVE: To explore adolescents' experiences using a newly developed mobile phone dietary assessment app, with a focus on factors that could affect their recording of dietary intake. METHODS: Focus group interviews were conducted with 75 participants who had used a newly developed mobile phone dietary assessment app in a quantitative evaluation study. The interviews were analyzed using qualitative content analysis and the theoretical framework of Self Determination Theory was applied. RESULTS: The adolescents' use of the mobile phone dietary assessment app was characterized by their struggle to overcome several perceived barriers. Facilitators that helped adolescents complete the method were also identified. Motivation was found to be an important facilitator, and intrinsically motivated participants completed the method because they found it fun to use. The autonomous extrinsically motivated participants completed the method for the greater good, in order to contribute to the study. The controlled extrinsically motivated participants completed the method to get a reward or avoid punishment. Amotivated participants did not complete the method. More motivated participants were assumed to be more able to overcome barriers and needed less facilitators. CONCLUSIONS: Future studies that examine the recording of food intake should include systematic efforts that aim to minimize identified barriers and promote identified facilitators. Further research should specifically aim at studying methods for (and effects of) increasing intrinsic motivation by supporting autonomy, competence, and relatedness among adolescents asked to participate in dietary studies.

A Mobile Phone App for Dietary Intake Assessment in Adolescents: An Evaluation Study.

BACKGROUND: There is a great need for dietary assessment methods that suit the adolescent lifestyle and give valid intake data. OBJECTIVE: To develop a mobile phone app and evaluate its ability to assess energy intake (EI) and total energy expenditure (TEE) compared with objectively measured TEE. Furthermore, to investigate the impact of factors on reporting accuracy of EI, and to compare dietary intake with a Web-based method. METHODS: Participants 14 to 16 years of age were recruited from year nine in schools in Gothenburg, Sweden. In total, 81 adolescents used the mobile phone app over 1 to 6 days. TEE was measured with the SenseWear Armband (SWA) during the same or proximate days. Individual factors were assessed with a questionnaire. A total of 15 participants also recorded dietary intake using a Web-based method. RESULTS: The mobile phone app underestimated EI by 29% on a group level (P<.001) compared to TEE measured with the SWA, and there was no significant correlation between EI and TEE. Accuracy of EI relative to TEE increased with a weekend day in the record (P=.007) and lower BMI z-score (P=.001). TEE assessed with the mobile phone app was 1.19 times the value of TEE measured by the SWA on a group level (P<.001), and the correlation between the methods was .75 (P<.001). Analysis of physical activity levels (PAL) from the mobile phone app stratified by gender showed that accuracy of the mobile phone app was higher among boys. EI, nutrients, and food groups assessed with the mobile phone app and Web-based method among 15 participants were not significantly different and several were significantly correlated, but strong conclusions cannot be drawn due to the low number of participants. CONCLUSIONS: By using a mobile phone dietary assessment app, on average 71% of adolescents' EI was captured. The accuracy of reported dietary intake was higher with lower BMI z-score and if a weekend day was included in the record. The daily question in the mobile phone app about physical activity could accurately rank the participants' TEE.

Dietary intake assessment in women with different weight and pregnancy status using a short questionnaire.

OBJECTIVE: First, to evaluate the ability of a short dietary questionnaire (SDQ) to estimate energy intake (EI) on group and individual levels compared with total energy expenditure (TEE) measured by the doubly labelled water method. Second, to compare the SDQ's performance in estimating energy, nutrient and food intakes with a sixty-six-item FFQ used in large-scale Swedish epidemiological research. DESIGN: Cross-sectional. SETTING: Umeå, Sweden. SUBJECTS: In total, sixty-five non-pregnant women, of whom thirty-one were overweight or obese, and twenty-five pregnant, normal-weight women completed the protocol. RESULTS: On average, the SDQ captured 78 % and 79 % of absolute TEE in the non-pregnant and pregnant normal-weight women, respectively. Furthermore, the SDQ captured an average of 57 % of TEE in the overweight/obese non-pregnant women. The Spearman correlation of EI and TEE was significant in the overweight and obese women only (ρ = 0·37, 95 % CI 0·02, 0·64). There was no significant difference between the SDQ and the more extensive FFQ in the ability to assess EI when compared with TEE. Intakes of most nutrients and foods were significantly higher when assessed with the SDQ compared with the FFQ. CONCLUSIONS: A new short dietary questionnaire with an alternative design underestimated EI of non-pregnant and pregnant, overweight and obese women on a group level but was able to rank the overweight/obese women according to EI. Furthermore, the short questionnaire captured as much or more of the energy, nutrient and food intakes of non-pregnant normal-weight and overweight/obese women on the group level as a traditional, more extensive FFQ.

Overweight and Obese Children's Ability to Report Energy Intake Using Digital Camera Food Records during a 2-Year Study.

The objective was to evaluate overweight and obese children's ability to report reproducible and valid estimates of energy intake (EI) by using digital camera food records (FR) during a 2-year study, compared with objectively measured total energy expenditure (TEE). Seventy-three overweight/obese children, aged 8-12 years at inclusion, kept FR with the help of digital cameras for 16 days in total, on 7 occasions during a 2-year period. On the same days, their TEE was registered with SenseWear Armband (SWA). The children underestimated their EI by -2.8 (2.4) MJ/d on the first assessment occasion (95% CI: -3.3, -2.3). Reporting accuracy did not differ between the 7 assessment occasions (P = 0.15). Variables negatively associated with reporting accuracy relative to TEE were increased age (95% CI: -0.07, -0.01) and BMI z-score (95% CI: -0.18, -0.06). Further, reporting accuracy relative to TEE was lower for girls than boys (95% CI: -0.14, -0.01) and on weekdays compared with weekend days (95% CI: -0.08, -0.001). In conclusion, overweight and obese children were able to report their EI using a digital camera FR with good reproducibility over a 2-year period, even though their EI was underestimated compared with objectively measured TEE.

The bisphosphonate, zoledronic acid reduces experimental neuroblastoma growth by interfering with tumor angiogenesis.

BACKGROUND: Zoledronic acid is a new member of the bisphosphonate (BP) class of compounds, a family of closely related synthetic molecules originally derived from the naturally occurring pyrophosphate. These compounds that are potent inhibitors of bone resorption, have been shown to reduce the growth of several cancer cell lines in vitro, and can act as inhibitors of angiogenesis. The angiogenesis inhibitor TNP-470, a synthetic analogue of the fungal antibiotic fumagillin, has been shown to inhibit the growth of multiple tumors in vivo, and is currently in Phase II clinical trials for cancer. MATERIALS AND METHODS: The effects of daily subcutaneous (s.c.) administration of zoledronic acid (0.1 mg/kg) were compared with those of TNP-470 (15 mg/kg/day and 30 mg/kg every other day, s.c.) in a nude mouse xenograft model for the childhood cancer, neuroblastoma (NB). RESULTS: Zoledronic acid reduced the tumor growth by 33% whereas TNP-470 was less effective and reduced the tumor growth by 26% and 11% for animals treated with 15 mg/kg/day and 30 mg/kg every other day, respectively. Analysis of angiogenesis showed a significant reduction of the number of vessels per grid and in vessel length in all the treatment groups. CONCLUSION: Zoledronic acid shows tumoristatic and angiostatic properties that might be beneficial in the treatment of solid tumors such as neuroblastoma.

Angiogenesis can be reduced without significant reduction of tumor growth.

BACKGROUND: High risk neuroblastoma (NB) patients have an overall five-year survival of approximately 50%, indicating the need for new treatment strategies, such as angiogenesis inhibition. MATERIALS AND METHODS: The angiogenesis inhibitor TNP-470 (30 mg/kg, every other day, subcutaneously) was given to nude mice with subcutaneous human neuroblastoma xenografts. The plasma concentrations of the angiogenesis stimulators, i.e. vascular endothelial growth factor A (VEGF-A), fibroblast growth factor 2 (FGF-2) and hepatocyte growth factor (HGF), were assayed longitudinally. Angiogenesis, proliferation and apoptosis were quantified on tumor tissue slides. RESULTS: Upon treatment with TNP-470, angiogenesis was significantly inhibited by the reduction of length and surface area of vessels per tumor volume, without having significant effect on tumor growth, tumor cell proliferation or apoptosis. Plasma concentrations of VEGF-A per tumor volume were significantly increased upon treatment. CONCLUSION: Angiogenesis inhibition must reach a threshold before significant tumor cell apoptosis and a reduction of the tumor growth rate occur.

Digoxin inhibits neuroblastoma tumor growth in mice.

BACKGROUND: Epidemiological data suggest a more favorable outcome of breast carcinoma in women taking cardiac glycosides. This study investigated whether digoxin could inhibit tumor growth in mice. MATERIALS AND METHODS: Tumor growth experiments were done in mice grafted with the neuroblastoma cell lines SH-SY5Y, Neuro-2a, colonic cancer cells (LS174T) or Lewis lung cancer cells (LLC). Angiogenesis inhibition was investigated in vitro on fibroblast growth factor-2 (FGF-2)-stimulated bovine endothelial cell (BCE) growth and in vivo in the chick chorioallantoic membrane (CAM) assay. RESULTS: SH-SY5Y and Neuro-2a grafts were inhibited by 44% (p=0.008) and 19% (p=0.007), respectively, whereas the colonic cancer xenografts and LLC syngrafts were less responsive. The neuroblastoma specificity was confirmed in vitro. Digoxin also inhibited angiogenesis in the CAM assay and the BCE cell survival in vitro was 50% at 53 ng/ml. CONCLUSION: Our data suggest that digoxin may be a specific neuroblastoma growth inhibitor and an unspecific inhibitor of angiogenesis.

CHS 828 inhibits neuroblastoma growth in mice alone and in combination with antiangiogenic drugs.

CHS 828 is a new chemotherapeutic drug, a pyridyl cyanoguanidine. CHS 828 has low toxicity and lacks known patterns of multidrug resistance. Here we report that oral, daily treatment with CHS 828 reduced the growth of SH-SY5Y human neuroblastoma tumors in male NMRI nu/nu mice by 82% without apparent toxicity. CHS 828 induced complete tumor regression for at least 5 weeks in four of nine animals (44%). Combination therapy with CHS 828 and the antiangiogenic drugs TNP-470 or SU5416 decreased neuroblastoma growth by a further 10 and 3%, respectively. Combination therapy induced tumor regression at d 4 with CHS plus TNP and d 6 with CHS plus SU5416, compared with d 14 with CHS 828 alone (p < 0.05), and complete tumor regression was seen in nine of 19 animals (47%). Combination treatment of CHS 828 and TNP-470 decreased the total viable tumor volume by 71% compared with treatment with CHS 828 alone. Our findings support CHS 828 as a promising new drug in treatment of childhood cancers. Furthermore, they imply efficiency of daily administration of nontoxic doses of chemotherapy, and a possible additive effect when chemotherapy is combined with angiogenesis inhibitors.

Importance of vascular endothelial growth factor A in the progression of experimental neuroblastoma.

Vascular endothelial growth factor A (VEGF-A) and its receptor tyrosine kinases located on endothelial cells seem to play an important role in the multistep pathway of angiogenesis. SU5416 is a small molecule which inhibits angiogenesis by acting as an inhibitor of VEGF receptor-2 tyrosine kinase. We have developed a reproducible murine model for neuroblastoma, a childhood cancer, based on s.c. xenotransplantation of SH-SY5Y neuroblastoma cells. We found that SH-SY5Y cells expressed VEGF-A on both the mRNA and protein levels, that plasma concentrations of VEGF-A were significantly elevated in animals with neuroblastoma with a volume > 1.4 ml, and that there was a correlation between VEGF-A levels in plasma and tumor size in untreated tumor-bearing animals. Treatment with SU5416 reduced the growth of neuroblastoma tumors by 65% without apparent toxicity. SU5416 treatment also suppressed tumor angiogenesis, despite an increase in plasma VEGF-A levels per ml tumor volume during therapy. Our experimental data suggest that the angiogenesis inhibitor SU5416 may be beneficial in the treatment of solid tumors of childhood such as neuroblastoma.
