RESUMO
Our aim was to explore the relationship between frailty, nutrition, body composition, and how gender modifies this relationship among long-term care facility residents. We further investigated how body composition correlates with health-related quality of life (HRQoL) in both genders. In all, 549 residents (> 65 years of age) were recruited from 17 long-term care facilities for this cross-sectional study. Demographic information, diagnoses, use of medications, and nutritional supplements were retrieved from medical records. Participants' frailty status, cognition, nutritional status, HRQoL, and body composition were determined. Energy, protein, and fat intakes were retrieved from 1- to 2-day food diaries. The final sample consisted of 300 residents (77% women, mean age 83 years). The majority of participants, 62% of women and 63% of men, were identified as frail. Frail participants in both genders showed lower body mass index (p = 0.0013), muscle mass (MM) (p < 0.001), poorer nutritional status (p = 0.0012), cognition (p = 0.0021), and lower HRQoL (p < 0.001) than did prefrail participants. Women had higher fat mass, whereas men exhibited higher MM. The HRQoL correlated with the MM in both women, r = 0.48 [95% CI 0.38, 0.57] and men r = 0.49 [95% CI 0.38, 0.58]. Interventions aimed at strengthening and retaining MM of long-term residents may also support their HRQoL.

OBJECTIVES: The objective of the study was to estimate associations between health locus of control (HLC) and mortality. STUDY DESIGN & METHODS: The public health survey in Scania 2008 was linked to the Swedish cause of death register. In this study of 10,757 men and 12,322 women aged 18-80 years, 421 men and 235 women died during the 5.3-year follow-up. Survival analyses were conducted. RESULTS: Respondents with only some or no internal HLC had significantly higher hazard rate ratios (HRRs) compared with respondents with high HLC. For women, the HRRs of those with low HLC did not significantly differ from the reference group after final adjustments for health-related behaviours. CONCLUSIONS: HLC is a predictor of mortality, and this association is to an important extent mediated by health-related behaviours.

OBJECTIVES: To investigate associations between sexual identity and low leisure-time physical activity (LTPA). STUDY DESIGN: Cross-sectional study. METHODS: The 2012 public health survey was conducted with a postal questionnaire in southern Sweden with 28,029 respondents, aged 18-80 years. Analyses were conducted with logistic regressions. RESULTS: The prevalence of low LTPA among men and women were as follows: 13.9% and 12.3% among heterosexuals, 26.1% and 18.5% among bisexuals, 19.5% and 15.6% among homosexuals, 26.6% and 18.5% among others. Bisexual men and women and other men had higher odds ratio of low LTPA than heterosexuals in the final models, whereas gay and lesbian participants did not differ. CONCLUSIONS: The results should guide health promotion and prevention.

OBJECTIVES: The purpose of this study was to analyse associations between sexual orientation and poor psychological health. STUDY DESIGN: This was a cross-sectional study. METHODS: The 2012 public health survey in Scania, Southern Sweden, is a cross-sectional population-based study with 28,029 participants aged 18-80 years. Logistic regression analyses were performed. RESULTS: The prevalence of poor psychological health (measured using the General Health Questionnaire [GHQ]-12) was 16.3% among men and 22.4% among women. Bisexual men and women had significantly higher odds ratios of poor psychological health throughout the multiple analyses than heterosexual individuals. In contrast, the odds ratios of poor psychological health among gay men and lesbian women were not significantly higher. CONCLUSIONS: Respondents with bisexual orientation have increased risk of poor psychological health.

OBJECTIVES: The aim was to investigate the association between baseline marital status and mortality using survival (Cox-regression) analysis. STUDY DESIGN: This is a prospective cohort study. METHODS: The public health survey by Scania in 2008 was linked to the Swedish cause of death register. This prospective cohort study includes 12,245 men and 14,969 women aged 18-80 years, and 538 men and 362 women of them died during the 5.3-year follow-up. RESULTS: Unmarried, divorced, and widowed men had significantly higher hazard rate ratios (HRRs) of all-cause mortality than married/cohabitating men. For women, the HRRs of these groups did not significantly differ from those of the married/cohabitating reference group. CONCLUSIONS: The results are in accordance with a previous study that only compared those living alone with those cohabitating.

OBJECTIVES: The aim was to investigate associations between e-cigarette use and social and psychosocial factors and cigarette smoking, alcohol consumption, and narcotics use among adolescents attending 9th grade in primary school and 2nd grade in secondary school. STUDY DESIGN: Cross-sectional study. METHODS: The public health survey among adolescents in Scania in 2016 includes pupils in grades 9 and 2. The associations between e-cigarette use and lifestyle, social and psychosocial factors, and trust were investigated with logistic regressions. RESULTS: In 9th grade, 32% of male pupils and 27% of female pupils had ever used e-cigarettes, and in 2nd grade, 43% of males and 31% of females had ever used e-cigarettes. E-cigarette use was significantly associated with current smoking, snus (a moist powder tobacco product originating in Sweden) use, water pipe use, intensive alcohol consumption, and narcotics and also with psychosocial conditions related to home and parents, peers, and school. CONCLUSIONS: The prevalence of ever e-cigarette use was high among adolescents attending both grades. E-cigarette use was most strongly associated with health-related lifestyles. It was also associated with psychosocial factors such as study difficulties, school stress, problems talking with parents, and generalized trust.

OBJECTIVES: To investigate associations between economic stress in childhood and suicide thoughts and attempts. STUDY DESIGN: The 2012 public health survey in Scania, Sweden, is a cross-sectional postal questionnaire study including 28,029 participants, aged 18-80 years. METHODS: Associations were analyzed in logistic regressions. RESULTS: A 12.1% prevalence of men and 15.5% of women had ever experienced suicide thoughts, while 3.2% of men and 5.3% of women had experienced suicide attempt. Roughly 24% had experienced less severe and 8% severe economic problems in childhood. Significant associations between economic stress in childhood and suicide thoughts and attempts remained throughout the age-adjusted and multiple adjusted analyses. CONCLUSIONS: Economic stress in childhood is associated with self-reported suicide thoughts and suicide attempts in an adult general population.

AIMS: The aim of this study was to investigate the associations between socioeconomic status (SES) and self-reported unmet health care needs, taking economic stress, generalized trust in other people and trust in the health care system into account. METHODS: The 2012 public health survey in Scania was conducted using a postal questionnaire and included 28,029 participants aged 18-80 years. The study was cross-sectional. Associations between SES and unmet health care needs were investigated, adjusting for economic stress and trust in logistic regressions. RESULTS: SES was significantly associated with unmet health care needs. The SES categories of unemployed, on long-term sick leave and unskilled manual workers reported particularly high levels of unmet health care needs. SES differences in unmet needs were attenuated when economic stress and the two dimensions of trust and self-rated health were introduced in multiple analyses. The working population gave a lack of time as the reason for unmet health care needs, whereas those on sick leave or unemployed reported a lack of money. CONCLUSIONS: SES differences in self-reported unmet health care needs were observed and these associations were attenuated when economic stress during the past year, generalized trust in other people, trust in the health care system and self-rated health were introduced into the multiple models.

The adrenalitis found in autoimmune Addison's disease (AAD) is considered having a Th1-driven pathogenesis. Circulating Th1- and Th2-associated chemokines responsible for the trafficking of leukocytes to inflammatory sites are markers for the Th1/Th2 balance. The aim of the study was to assess if the same daily hydrocortisone dose of 30 mg given in either 2 or 4 doses to patients with AAD could affect the Th1/Th2 balance of circulating chemokines.Fifteen patients (6 women) with AAD were included in this randomised, placebo controlled, double blind cross-over study. Samples for chemokines, Th1-associated (CXCL10, CXCL11) and Th2-associated (CCL17, CCL22), were drawn 5 times during a 24-h period at the end of each treatment period and analysed with Luminex. Seven control subjects did the same diurnal blood sampling once. Subjects with AAD had higher median diurnal levels of the Th1-associated chemokines than controls, CXCL10 [43 (33-56) pg/ml vs. 22 (19-34) pg/ml, p<0.01] and CXCL11 [37 (29-48) pg/ml vs. 16 (9-24) pg/ml, p<0.001], whereas no significant difference was found regarding the Th2-related chemokines. Similar chemokine levels were found when the same hydrocortisone dose of 30 mg was divided in 2 or 4 doses. Levels of CXCL11 correlated negatively with scores of SF-36 domains (high score indicate better health) of General Health (GH) and total score for Physical Component Summary (PCS), and these negative correlations were most pronounced at 04:00 h on the 2-dose regimen. Patients with AAD have a dominant Th1 chemokine profile that partially correlates to reduced quality of life.

In Finland in April 2010, a 3-month old baby was diagnosed with type A infant botulism. He excreted botulinum neurotoxin and/or Clostridium botulinum in his faeces until November 2010. Five months of excretion was after clinical recovery and discharge from hospital. C. botulinum isolates recovered from the household dust in the patient's home were genetically identical to those found in the infant's stool samples. Long-term faecal excretion of C. botulinum may pose a possible health risk for the parents and others in close contact with the infant.

Computed tomography (CT) was used to explore if changes in muscle cross-sectional area and quality after anterior cruciate ligament (ACL) injury and reconstruction would be related to knee function. Fourteen females and 23 males (16-54 years) underwent clinical tests, subjective questionnaires, and CT 1 week before and 1 year after ACL surgery with semitendinosus-gracilis (STG) graft and rehabilitation. Postoperatively, knee laxity was decreased and functional knee measures and subjective patient scores improved. The most obvious remaining deficit was the quadriceps atrophy, which was significantly larger if the right leg was injured. Right-leg injury also tended to cause larger compensatory hypertrophy of the combined knee flexor and tibial internal rotator muscles (preoperatively). The quadriceps atrophy was significantly correlated with the scores and functional tests, the latter also being related to the remaining size of the gracilis muscle. Biceps femoris hypertrophy and, in males only, semimembranosus hypertrophy was observed following the ACL reconstruction. The lack of semimembranosus hypertrophy in the women could, via tibial internal rotation torque deficit, contribute to the less favorable functional and subjective outcome recorded for the women. The results indicate that the quadriceps, the combined knee flexor/tibial internal rotator muscles, side of ACL injury, and sex are important to consider in rehabilitation after STG graft.

AIMS/HYPOTHESIS: The study aimed to compare the effects of a 2 year intervention with a low-fat diet (LFD) or a low-carbohydrate diet (LCD), based on four group meetings to achieve compliance. METHODS: This was a prospective randomised parallel trial involving 61 adults with type 2 diabetes consecutively recruited in primary care and randomised by drawing ballots. Patients that did not speak Swedish could not be recruited. The primary outcomes in this non-blinded study were weight and HbA(1c). Patients on the LFD aimed for 55-60 energy per cent (E%) and those on LCD for 20 E% from carbohydrate. RESULTS: The mean BMI and HbA(1c) of the participants were 32.7 ± 5.4 kg/m(2) and 57.0 ± 9.2 mmol/mol, respectively. No patients were lost to follow-up. Weight loss did not differ between groups and was maximal at 6 months: LFD -3.99 ± 4.1 kg (n=31); LCD -4.31 ± 3.6 kg (n=30); p < 0.001 within groups. At 24 months, patients on the LFD had lost -2.97 ± 4.9 kg and those on LCD -2.34 ± 5.1 kg compared with baseline (p = 0.002 and p = 0.020 within groups, respectively). HbA(1c) fell in the LCD group only (LCD at 6 months -4.8 ± 8.3 mmol/mol, p = 0.004, at 12 months -2.2 ± 7.7 mmol/mol, p = 0.12; LFD at 6 months -0.9 ± 8.8 mmol/mol, p = 0.56). At 6 months, HDL-cholesterol had increased with the LCD (from 1.13 ± 0.33 mmol/l to 1.25 ± 0.47 mmol/l, p = 0.018) while LDL-cholesterol did not differ between groups. Insulin doses were reduced in the LCD group (0 months, LCD 42 ± 65 E, LFD 39 ± 51 E; 6 months, LCD 30 ± 47 E, LFD 38 ± 48 E; p = 0.046 for between-group change). CONCLUSIONS/INTERPRETATION: Weight changes did not differ between the diet groups, while insulin doses were reduced significantly more with the LCD at 6 months, when compliance was good. Thus, aiming for 20% of energy intake from carbohydrates is safe with respect to cardiovascular risk compared with the traditional LFD and this approach could constitute a treatment alternative.

OBJECTIVES: To investigate the association between marital status and lack of internal health locus of control (HLC), taking economic stress and trust into account. STUDY DESIGN: Cross-sectional study. METHODS: The public health survey Skåne 2008 is a postal questionnaire study (55% participation rate). A random sample was invited to participate, and 28,198 individuals aged 18-80 years agreed. Logistic regression models were used to discern associations between marital status and lack of internal HLC. The multiple regression analyses included age, country of birth, education, economic stress and 'horizontal' trust. RESULTS: In total, 33.7% of the men and 31.8% of the women lacked internal HLC. After age-adjustments, the unmarried and divorced men and the widowed women displayed significantly higher odds ratios of lack of internal HLC. The significantly higher odds ratios only remained for unmarried men throughout the multiple analyses. In contrast, divorced women had significantly lower odds ratios of lack of internal HLC than married women after adjustments for economic stress. CONCLUSIONS: Health promotion regarding HLC and related behaviours should consider men and women who are not cohabiting. Health promotion should particularly consider unmarried men due to their higher propensity to lack internal HLC. The economic conditions and exposure to economic stress among widowed and divorced women should also be highlighted.

BACKGROUND: The clinical course of World Health Organisation grade II gliomas remains variable and their time point of transformation into a more malignant phenotype is unpredictable. Identification of biological markers that can predict prognosis in individual patients is of great clinical value. PROX1 is a transcription factor that has a critical role in the development of various organs. PROX1 has been ascribed both oncogenic and tumour suppressive functions in human cancers. We have recently shown that PROX1 may act as a diagnostic marker for high-grade gliomas. The aim of this study was to address the prognostic value of PROX1 in grade II gliomas. METHODS: A total of 116 samples were evaluated for the presence of PROX1 protein. The number of immunopositive cells was used as a variable in survival analysis, together with established prognostic factors for this patient group. RESULTS: Higher PROX1 protein was associated with poor outcome. In the multivariate analysis, PROX1 was identified as an independent factor for survival (P=0.024), together with the presence of mutated isocitrate dehydrogenase 1 R132H protein, and with combined losses of chromosomal arms 1p/19q in oligodendrocytic tumours. CONCLUSION: PROX1 is a novel predictor of survival for grade II gliomas.

In October 2011 in Finland, two persons fell ill with symptoms compatible with botulism after having eaten conserved olives stuffed with almonds. One of these two died. Clostridium botulinum type B and its neurotoxin were detected in the implicated olives by PCR and mouse bioassay, respectively. The olives were traced back to an Italian manufacturer and withdrawn from the market. The public and other European countries were informed through media and Europe-wide notifications.

OBJECTIVES: To investigate the associations between social capital (trust) and leisure-time physical activity. STUDY DESIGN: The 2004 Public Health Survey in Skåne is a cross-sectional study. METHODS: In total, 27,757 individuals aged 18-80 years answered a postal questionnaire (59% participation). Logistic regression models were used to investigate the associations between trust, desire to increase physical activity and leisure-time physical activity. RESULTS: The prevalence of low leisure-time physical activity was 15.3% among men and 13.2% among women. Middle-aged men and older women, respondents born abroad, those with medium/low education, those with the desire to increase physical activity but needing support, and those reporting low trust had significantly higher odds ratios of low leisure-time physical activity than their respective reference groups. The associations between low trust and desire to increase physical activity and between low trust and low leisure-time physical activity remained in the multiple models. CONCLUSIONS: The positive association between low trust and low leisure-time physical activity remained after multiple adjustments. There is a concentration of men and women with low leisure-time physical activity who report the desire to increase their physical activity but think that they need support to do so. This group also has a significantly higher prevalence of low trust.

SUMMARY: Providers diagnose hypercalciuria using a 24-hour or random urine samples. We compared calcium measurements from paired 24-hour and morning urine samples; measurements correlated poorly. We developed a formula to correct random urine calcium levels. Corrected levels showed excellent agreement with 24-hour measurements. Until validation, providers should diagnose hypercalciuria using 24-hour tests. INTRODUCTION: Hypercalciuria is a risk factor for osteoporosis and nephrolithiasis. The 24-hour urine calcium (24HUC) measurement is the gold standard to diagnose hypercalciuria, but the spot urine calcium-to-creatinine ratio (SUCCR) is more convenient. Although authors claim they are interchangeable, we observed inconsistencies during the conduct of a clinical trial. Therefore, we systematically evaluated agreement between the tests. METHODS: During a 28-inpatient calcium absorption studies in 16 postmenopausal women, we simultaneously collected paired fasting morning and 24-hour urine specimens. RESULTS: We found moderate correlation between paired SUCCR and 24HUC specimens (r = 0.57, p = 0.002), but the SUCCR underestimated 24HUC by a mean of 83 mg (Bland-Altman). We diagnosed hypercalciuria (24HUC >250 mg) in eight specimens using the 24HUC, but only in two specimens using the SUCCR (25% sensitivity). We developed a regression model to predict 24HUC using SUCCR, parathyroid hormone, body mass index, and 1,25(OH)(2)D. The model improved diagnostic sensitivity to 100% and decreased Bland-Altman bias of the SUCCR to +0.06 mg/kg/24-hour. CONCLUSIONS: We conclude that the SUCCR underestimates urine calcium loss and does not reliably diagnose hypercalciuria. A formula derived from multivariate regression incorporating other readily measurable variables greatly improved the SUCCR's accuracy. Future studies must verify this correction before clinical implementation.

A clast of spinel troctolite containing 8 percent cordierite (Mg(2)Al(4)Si(5)O(18)) has been identified among the constituents of Apollo 15 regolith breccia 15295. The cordierite and associated anorthite, forsteritic olivine, and pleonaste spinel represent a new, Mg-rich lunar highlands lithology that formed by metamorphism of an igneous spinel cumulate. The cordierite-forsterite pair in the assemblage is stable at a maximum pressure of 2.5 kilobars, equivalent to a depth of 50 kilometers, or 10 kilometers above the lunar crust-mantle boundary. The occurrence of the clast indicates that spinel cumulates are a more important constituent of the lower lunar crust than has been recognized. The rarity of cordierite-spinel troctolite among lunar rock samples suggests that it is excavated only by large impact events, such as the one that formed the adjacent Imbrium Basin.
RESUMO
Abundant fossil meteorites in marine, condensed Lower Ordovician limestones from Kinnekulle, Sweden, indicate that accretion rates of meteorites were one to two orders of magnitude higher during an interval of the Early Ordovician than at present. Osmium isotope and iridium analyses of whole-rock limestone indicate a coeval enhancement of one order of magnitude in the influx rate of cosmic dust. Enhanced accretion of cosmic matter may be related to the disruption of the L chondrite parent body around 500 million years ago.

OBJECTIVE: A positive attitude is assumed to be important in nursing staff's help and support of elderly people during meals. As there is no specific tool for measuring staff's attitudes regarding important issues within eating and nutrition, the SANN (Staff Attitudes to Nutritional Nursing Care) scale was developed. The scale was developed and tested in nursing staff working at resident homes, and the number of items was reduced from 63 to 19 with five underlying factors. The aim of this study was to describe how the SANN scale was adapted and tested in nursing staff working in different types of elderly care. DESIGN: The raw 63-item version went through minor changes, and one unclear worded item was excluded. The changed raw 62-item version was answered by 188 nursing staff working at six hospital care clinics and 64 staff working at one resident home. RESULTS: The analysis reduced the 62 items to 18, and the adapted scale was named the SANN-G scale, G standing for "geriatric care". A rotated factor analysis gave a five-factor solution, explaining 54% of the variance. The scale achieved good internal reliability, with a Cronbach's alpha of 0.83. Fourteen items fulfilled inclusion criteria in both the SANN and the SANN-G scales. CONCLUSION: The SANN-G scale is practicable for use in staff working in different types of elderly care. It can be used to explore existing attitudes and identify areas with a low degree of prevailing positive attitudes as well as to evaluate whether and how attitudes change after nutritional education and intervention.
