Exploring longitudinal relationships between fitness tracking and disordered eating outcomes in college-aged women.

OBJECTIVE: A growing body of research, primarily cross-sectional, suggests a relationship between the practice of tracking one's food intake and exercise behaviors using fitness-tracking smartphone applications ("apps") or wearable devices ("wearables") and disordered eating symptomatology. The aim of the present study was to explore longitudinal relationships between fitness tracking and disordered eating outcomes among college-aged women, as well as to determine whether the individual-level risk factors of pre-existing eating concerns, perfectionism, and rumination about food moderated the relationship. METHOD: N = 68 female undergraduates used the MyFitnessPal app for 8 weeks while completing a series of self-report measures. RESULTS: At the trait level, fitness tracking frequency was positively associated with weight/shape concerns, but not with the other outcome measures. Daily levels of fitness tracking did not predict next-day levels for any of the outcome measures. Within-day fitness tracking at one timepoint was associated with lower reports of dietary restraint efforts at the next timepoint. None of the proposed moderators significantly interacted with the relationships over time. DISCUSSION: These results suggest that while those who engage in fitness tracking may experience higher weight/shape concerns as a trait, over time fitness tracking was not associated with an increase in concerns. Further work exploring whether fitness tracking may affect particular subgroups in different ways is warranted.

Holistic Hypertension Management.

Hypertension (HTN) is a major health care problem affecting nearly half of American's adult population. HTN is one of the costliest diagnoses among cardiovascular disease and leads to other major cardiovascular complications, which increase overall morbidity and mortality. Of those diagnosed with HTN in America, only one-fourth of patients are living with well-controlled HTN. This evidenced-based HTN management practice innovation was conducted to explore evidenced-based, holistic nursing practice of a low-sodium dietary approach to stop hypertension (DASH) diet, and exercise alongside antihypertensive medication management in decreasing systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adult patients diagnosed with HTN. This community-based holistic care initiative supports data previously published, which suggests a low-sodium DASH diet, exercise, and antihypertensive medication management are effective in decreasing SBP and DBP. This project supported clinicians seeking to integrate a complementary holistic and traditional approach to HTN management in patients diagnosed with HTN.

Bactericidal effects of high-energy visible light on common otitis media pathogens.

AIMS: This study assessed the use of high-energy, visible light on the survival rates of three bacteria commonly found in middle ear infections (i.e. otitis media; Streptococcus pneumoniae, Moraxella catarrhalis and Haemophilus influenzae). METHOD AND RESULTS: Bacteria were cultured and then subjected to a single, 4-h treatment of 405 nm wavelength light at two different intensities. All three bacteria species were susceptible to the light at clinically significant rates (>99.9% reduction). Bacteria were susceptible to the high-energy visible (HEV) light in a dose-dependent manner (lower survival rates with increased intensity and duration of exposure). CONCLUSIONS: The results suggest that HEV light may provide a non-surgical, non-pharmaceutical approach to the therapeutic treatment of otitis media. SIGNIFICANCE AN IMPACT OF THE STUDY: Given the growing concerns surrounding antibiotic resistance, this study demonstrates a rapid, alternative method for effective inactivation of bacterial pathogens partly responsible for instances of otitis media.

Body image concerns and disordered eating among older women: Identifying variables of interest for integrated models.

OBJECTIVE: Research focused on developing risk and protective models of body image concerns and disordered eating among older women is scant. Models including biological, psychological, and sociocultural elements may be useful explanatory frameworks in this group. Thus, the aim of this study was to conduct formative research exploring the constructs that form part of biopsychosocial models of body image concerns and disordered eating among older women. METHOD: A sample of 184 women aged 60-75 years completed an online survey assessing media pressures, thin-ideal internalization, depression symptoms, weight and shape concerns, and disordered eating as well as positive reappraisal and acceptance of aging-related changes to appearance. RESULTS: After the addition of two supplemental pathways, the model revealed good fit to the data. In the final model, age, depression, and media pressure were associated with media internalization, that was in turn associated with weight and shape concerns, and then disordered eating. Depression was also directly associated with both weight and shape concerns and disordered eating. The model varied across older women with high versus low levels of positive reappraisal and acceptance of aging-related changes to appearance. Specifically, among those high on this trait, the pathways between depression and thin-ideal internalization, and between weight and shape concerns and disordered eating were significantly weaker. DISCUSSION: These findings support the usefulness of biopsychosocial models for grounding research on body image concerns and disordered eating among older women, and suggest positive reappraisal and acceptance of aging-related changes to appearance as a useful dimension to focus on.

A qualitative investigation of Orthorexia Nervosa among U.S. college students: Characteristics and sociocultural influences.

BACKGROUND: Current studies on Orthorexia Nervosa (ON) are predominantly correlational and have largely been conducted outside of the U.S. with little attention to cultural aspects. This study aimed to qualitatively examine ON-related attitudes and behaviors among U.S. college students, with a particular focus on exploring concerns related to healthy eating and diet quality as defined by proposed diagnostic criteria, body image concerns and disordered eating, and sociocultural influences. METHOD: Eighteen women and 3 men, aged 18-23 years (M = 19.5, SD = 1.6), who had reported high levels of ON symptoms participated in individual interviews. Interviews were transcribed verbatim and examined for evidence of the proposed diagnostic criteria of ON. In addition, thematic analysis was conducted to examine concurrent body image and eating concerns, as well as sociocultural influences. RESULTS: The patterns of the presence of diagnostic criteria varied, with the importance of food quality, and associated severely restricted eating patterns emerging as some of the most common elements. Six themes emerged from the thematic analysis: healthy eating concerns and diet quality, frequency and nature of food-related thoughts, definitions of healthy eating and healthy foods, disordered eating and body image, interpersonal social influence, and media and other influence from the broader social context. DISCUSSION: The findings suggest that ON symptoms may be concurrent with, or an evolution of other eating disorder presentations. In addition, our results highlight the role of family and sociocultural factors in ON, pointing to the usefulness of examining these behaviors within sociocultural frameworks that have been successfully applied to other types of disordered eating.

Orthorexia nervosa, intuitive eating, and eating competence in female and male college students.

Orthorexia nervosa (ON) has emerged as a new pattern of disordered eating behaviors characterized by preoccupations related to diet quality and health concerns, rather than driven by weight and shape concerns. A growing body of cross-sectional empirical data has documented associations between orthorexia nervosa symptoms and other indicators of disordered eating. However, little attention has been paid to the potential relationship between ON symptoms and indicators of healthy eating or positive eating behaviors. The aim of the present study was therefore to evaluate the relationships between ON symptomatology and the different facets of intuitive eating and eating competence. A sample of n = 605, 19% male, college students from the USA completed an online survey assessing orthorexia nervosa behaviors, the four facets of intuitive eating, and eating competence. Overall, orthorexia nervosa behaviors were found to be associated with lower levels of positive eating attitudes and behaviors. However, among men, curvilinear convex relationships emerged for two facets of intuitive eating, Body-Food Choice Congruence and Reliance on Hunger and Satiety Cues, such that the highest levels of intuitive eating were reported by those with mid-range levels of orthorexia nervosa behaviors. Taken together, these findings suggest that broadly, patterns of eating characterized by restriction, albeit for health reasons, are associated with less positive eating behaviors particularly among women. Further work focused on evaluating how drive for a healthy diet can be associated with flexible and positive eating patterns is warranted.Level of evidence Level V descriptive cross-sectional study.

An examination of trends in antibiotic prescribing in primary care and the association with area-level deprivation in England.

BACKGROUND: Internationally, there are growing concerns about antimicrobial resistance. This has resulted in increased scrutiny of antibiotic prescribing trends - particularly in primary care where the majority of prescribing occurs. In England, antibiotic prescribing targets are set nationally but little is known about the local context of antibiotic prescribing. This study aimed to examine trends in antibiotic prescribing (including broad-spectrum), and the association with area-level deprivation and region in England. METHODS: Antibiotic prescribing data by GP surgery in England were obtained from NHS Business Service Authority for the years 2014-2018. These data were matched with the Index of Multiple Deprivation (IMD) 2015 at the Lower Layer Super Output Area level Lower Layer Super Output Area (LSOA) level. Linear regression methods were employed to explore the relationship between antibiotic use and area-level deprivation as well as region, after controlling for a range of other confounding variables, including health need, rurality, and ethnicity. RESULTS: Over time, the amount of antibiotic prescribing significantly reduced from 1.11 items per STAR-PU to 0.96 items per STAR-PU - a reduction of 13.6%. The adjusted models found that, at LSOA level, the most deprived areas of England had the highest levels of antibiotic prescribing (0.03 items per STAR-PU higher). However, broad spectrum antibiotic prescribing exceeding 10% of all antibiotic prescribing within a GP practice was higher in more affluent areas. There were also significant regional differences - with the North East and the East of England having the highest levels of antibiotic prescribing (by 0.16 items per STAR-PU). CONCLUSION: Although antibiotic prescribing has reduced over time, there remains significant variation in by area-level deprivation and region in England - with higher antibiotic prescribing in more deprived areas. Future prescribing targets should account for local factors to ensure the most deprived communities are not inappropriately penalised.

Eating Disorders in Ethnic Minorities: an Update.

PURPOSE OF REVIEW: Eating disorders are recognized to occur across ethnic and racial groups. The aim of the present review was to examine recent advances in the understanding of the development, presentation, and intervention approaches specific to eating disorders among ethnic and racial minority groups. RECENT FINDINGS: An increasing number of measures have been found to be useful tools for assessing eating disorder risk and symptoms among ethnic and racial minority populations. In addition, further evidence has emerged supporting the relationship between higher levels of eating disorder symptoms and acculturation stress, as well as investment in appearance ideals. In contrast, the relationship between ethnic identity and eating disorder symptoms is less consistent, although several studies suggest that positive ethnic identity may be protective. Finally, increasing efforts have been made to develop and implement culturally sensitive interventions by tailoring evidence-supported treatments. Our understanding of and capacity to treat eating disorders among ethnic and racial minority groups continues to improve. However, further research is needed, particularly among neglected groups, such a smaller ethnic and racial groups, males, and intersecting minority statuses.

A novel retractable laparoscopic device for mapping gastrointestinal slow wave propagation patterns.

BACKGROUND: Gastric slow waves regulate peristalsis, and gastric dysrhythmias have been implicated in functional motility disorders. To accurately define slow wave patterns, it is currently necessary to collect high-resolution serosal recordings during open surgery. We therefore developed a novel gastric slow wave mapping device for use during laparoscopic procedures. METHODS: The device consists of a retractable catheter constructed of a flexible nitinol core coated with Pebax. Once deployed through a 5-mm laparoscopic port, the spiral head is revealed with 32 electrodes at 5 mm intervals. Recordings were validated against a reference electrode array in pigs and tested in a human patient. RESULTS: Recordings from the device and a reference array in pigs were identical in frequency (2.6 cycles per minute; p = 0.91), and activation patterns and velocities were consistent (8.9 ± 0.2 vs 8.7 ± 0.1 mm s-1; p = 0.2). Device and reference amplitudes were comparable (1.3 ± 0.1 vs 1.4 ± 0.1 mV; p = 0.4), though the device signal-to-noise ratio was higher (17.5 ± 0.6 vs 12.8 ± 0.6 dB; P < 0.0001). In the human patient, corpus slow waves were recorded and mapped (frequency 2.7 ± 0.03 cycles per minute, amplitude 0.8 ± 0.4 mV, velocity 2.3 ± 0.9 mm s-1). CONCLUSION: In conclusion, the novel laparoscopic device achieves high-quality serosal slow wave recordings. It can be used for laparoscopic diagnostic studies to document slow wave patterns in patients with gastric motility disorders.

Inventory of surveillance systems assessing dietary, physical activity and sedentary behaviours in Europe: a DEDIPAC study.

Background: There is a need for harmonized public health surveillance systems to monitor regional variations and temporal trends of health behaviours and health outcomes and to align policies, action plans and recommendations in terms of healthy diet and physical (in)activity within Europe. We provide an inventory of currently existing surveillance systems assessing diet, physical activity, and sedentary behaviours in Europe as a tool to assist in the identification of gaps and needs and to contribute to the roadmap for an integrated pan-European surveillance system. Methods: An inventory questionnaire was completed by representatives of eleven European countries. Eligible surveillance systems were required to meet specific inclusion criteria. First, pre-screening of available surveillance systems in each country was conducted. Second, an in-depth appraisal of the retained surveillance systems complying with the pre-defined requirements was performed. Results: Fifty surveillance systems met the inclusion criteria: six multinational European surveys and forty-four national surveys. Dietary intake and physical activity are the domains predominantly assessed and adults are the most frequently studied age group. Conclusions: Many on-going activities were identified at the national level focussing on adults, but fewer surveillance systems involving vulnerable groups such as infants and pre-school children. Assessment of sedentary and dietary behaviours should be more frequently considered. There is a need for harmonization of surveillance methodologies, indicators and target populations for between-country and over time comparisons. This inventory will serve to feed future discussions within the DEDIPAC-JPI major framework on how to optimize design and identify priorities within surveillance.

Functional physiology of the human terminal antrum defined by high-resolution electrical mapping and computational modeling.

High-resolution (HR) mapping has been used to study gastric slow-wave activation; however, the specific characteristics of antral electrophysiology remain poorly defined. This study applied HR mapping and computational modeling to define functional human antral physiology. HR mapping was performed in 10 subjects using flexible electrode arrays (128-192 electrodes; 16-24 cm2) arranged from the pylorus to mid-corpus. Anatomical registration was by photographs and anatomical landmarks. Slow-wave parameters were computed, and resultant data were incorporated into a computational fluid dynamics (CFD) model of gastric flow to calculate impact on gastric mixing. In all subjects, extracellular mapping demonstrated normal aboral slow-wave propagation and a region of increased amplitude and velocity in the prepyloric antrum. On average, the high-velocity region commenced 28 mm proximal to the pylorus, and activation ceased 6 mm from the pylorus. Within this region, velocity increased 0.2 mm/s per mm of tissue, from the mean 3.3 ± 0.1 mm/s to 7.5 ± 0.6 mm/s (P < 0.001), and extracellular amplitude increased from 1.5 ± 0.1 mV to 2.5 ± 0.1 mV (P < 0.001). CFD modeling using representative parameters quantified a marked increase in antral recirculation, resulting in an enhanced gastric mixing, due to the accelerating terminal antral contraction. The extent of gastric mixing increased almost linearly with the maximal velocity of the contraction. In conclusion, the human terminal antral contraction is controlled by a short region of rapid high-amplitude slow-wave activity. Distal antral wave acceleration plays a major role in antral flow and mixing, increasing particle strain and trituration.

WT1 regulates the expression of inhibitory chemokines during heart development.

The embryonic epicardium is an important source of cardiovascular precursor cells and paracrine factors that are required for adequate heart formation. Signaling pathways regulated by WT1 that promote heart development have started to be described; however, there is little information on signaling pathways regulated by WT1 that could act in a negative manner. Transcriptome analysis of Wt1KO epicardial cells reveals an unexpected role for WT1 in repressing the expression of interferon-regulated genes that could be involved in a negative regulation of heart morphogenesis. Here, we showed that WT1 is required to repress the expression of the chemokines Ccl5 and Cxcl10 in epicardial cells. We observed an inverse correlation of Wt1 and the expression of Cxcl10 and Ccl5 during epicardium development. Chemokine receptor analyses of hearts from Wt1(gfp/+) mice demonstrate the differential expression of their chemokine receptors in GFP(+) epicardial enriched cells and GFP(-) cells. Functional assays demonstrate that CXCL10 and CCL5 inhibit epicardial cells migration and the proliferation of cardiomyocytes respectively. WT1 regulates the expression levels of Cxcl10 and Ccl5 in epicardial cells directly and indirectly through increasing the levels of IRF7. As epicardial cell reactivation after a myocardial damage is linked with WT1 expression, the present work has potential implications in adult heart repair.

A self-avoidance mechanism in patterning of the urinary collecting duct tree.

BACKGROUND: Glandular organs require the development of a correctly patterned epithelial tree. These arise by iterative branching: early branches have a stereotyped anatomy, while subsequent branching is more flexible, branches spacing out to avoid entanglement. Previous studies have suggested different genetic programs are responsible for these two classes of branches. RESULTS: Here, working with the urinary collecting duct tree of mouse kidneys, we show that the transition from the initial, stereotyped, wide branching to narrower later branching is independent from previous branching events but depends instead on the proximity of other branch tips. A simple computer model suggests that a repelling molecule secreted by branches can in principle generate a well-spaced tree that switches automatically from wide initial branch angles to narrower subsequent ones, and that co-cultured trees would distort their normal shapes rather than colliding. We confirm this collision-avoidance experimentally using organ cultures, and identify BMP7 as the repelling molecule. CONCLUSIONS: We propose that self-avoidance, an intrinsically error-correcting mechanism, may be an important patterning mechanism in collecting duct branching, operating along with already-known mesenchyme-derived paracrine factors.

Acute multiple organ failure in adult mice deleted for the developmental regulator Wt1.

There is much interest in the mechanisms that regulate adult tissue homeostasis and their relationship to processes governing foetal development. Mice deleted for the Wilms' tumour gene, Wt1, lack kidneys, gonads, and spleen and die at mid-gestation due to defective coronary vasculature. Wt1 is vital for maintaining the mesenchymal-epithelial balance in these tissues and is required for the epithelial-to-mesenchyme transition (EMT) that generates coronary vascular progenitors. Although Wt1 is only expressed in rare cell populations in adults including glomerular podocytes, 1% of bone marrow cells, and mesothelium, we hypothesised that this might be important for homeostasis of adult tissues; hence, we deleted the gene ubiquitously in young and adult mice. Within just a few days, the mice suffered glomerulosclerosis, atrophy of the exocrine pancreas and spleen, severe reduction in bone and fat, and failure of erythropoiesis. FACS and culture experiments showed that Wt1 has an intrinsic role in both haematopoietic and mesenchymal stem cell lineages and suggest that defects within these contribute to the phenotypes we observe. We propose that glomerulosclerosis arises in part through down regulation of nephrin, a known Wt1 target gene. Protein profiling in mutant serum showed that there was no systemic inflammatory or nutritional response in the mutant mice. However, there was a dramatic reduction in circulating IGF-1 levels, which is likely to contribute to the bone and fat phenotypes. The reduction of IGF-1 did not result from a decrease in circulating GH, and there is no apparent pathology of the pituitary and adrenal glands. These findings 1) suggest that Wt1 is a major regulator of the homeostasis of some adult tissues, through both local and systemic actions; 2) highlight the differences between foetal and adult tissue regulation; 3) point to the importance of adult mesenchyme in tissue turnover.

Strike a pose: Immediate effects of a model-created social media literacy video on body image and mood.

Exposure to idealized social media imagery has been shown to be detrimental to body image among young women, and social media literacy may be protective. This mixed methods study aimed to evaluate the effects of an online video narrated by a high-profile, plus-size model on the body image and negative mood of young women and predictors of the effects. A sample of 304 young women, average age 20.95 (SD = 2.09) years, completed an online survey including pre- and post-exposure measures of state body image and negative mood, and trait measures of upward social media appearance comparison, thin-ideal internalization, and selfie-investment. A subset (n = 148) responded to open-ended questions to obtain feedback on the video coded categorically and through thematic analysis. Findings revealed immediate improvements in state body satisfaction and negative mood, with higher levels of trait appearance comparison and selfie investment associated with smaller effects of the video. Participants endorsed the video as raising awareness of unrealistic images but limited in terms of mitigating appearance comparison and selfie-investment. Furthermore, participants described that Iskra's status as a professional model also influenced their reactions. These findings highlight the importance of assessing for unintended paradoxical effects of social media literacy efforts and ensuring that such interventions are empirically based.

Types, predictors, and consequences of medicines related problems (MRPs) in frail older adults admitted to hospital from primary care - A retrospective cohort study.

Introduction: Medicines related problems (MRPs) can be common in frail older people due to age-compromised body systems and a propensity to be on multiple drugs concurrently. This group of people can also succumb to a rapid deterioration in health. Thus, it is important to investigate MRPs in frail older people. The objectives of the study were to evaluate prevalence of MRPs, types of MRPs, risk factors and deterioration that can be associated with MRPs in frail older people admitted to an English teaching hospital from primary care. Methods: Included in the sample were frail older adults, aged 65 years and over, admitted from primary care. Data was retrieved from the hospital's electronic patient record system, anonymised, and reviewed for MRPs. MRPs which were retrospectively identified at admission were coded with the WHO-ICD10,2016 (World Health Organisation-International Classification of Diseases version 10, 2016). Descriptive and inferential statistics were performed on the data using SPSS Version 25. Primary outcome was the prevalence of MRPs in frail older patients. Secondary outcome was the association of deterioration indicated as fall, delirium, or NEWs ≥3 with presence of MRPs. Results: Among the 507 frail older people (≥4 on Rockwood scale) that met criteria for inclusion, 262 (51.8%) were patients with MRPs and 244 (48.2%) without. The Median age of sample as a whole was 85 years (IQR = 80-89). Prevalence of MRPs was 33.28%. Types of MRPs were adverse drug reaction (ADR-20%), non-compliance (9.1%), unintentional poisoning (3.3%) and inappropriate polypharmacy (0.8%). In logistic regression, potentially inappropriate medicines (PIM), social support, number of comorbidities and winter were significant predictors of MRPs. Risk of deteriorating with delirium was two times higher in patients with MRPs than in patients without MRPs, RR 2.613 (95% CI, 1.049 to 6.510). Conclusion: MRPs and risks of deterioration associated with MRPs in frail older people can be reduced. This is because factors associated with MRPs can be modified.

Esrrg functions in early branch generation of the ureteric bud and is essential for normal development of the renal papilla.

Congenital anomalies of the kidney and urinary tract (CAKUTs) are common disorders of human development affecting the renal parechyma, renal pelvis, ureter, bladder and urethra; they show evidence of shared genetic aetiology, although the molecular basis of this remains unknown in the majority of cases. Breakpoint mapping of a de novo, apparently balanced, reciprocal translocation associated with bilateral renal agenesis has implicated the gene encoding the nuclear steroid hormone receptor ESRRG as a candidate gene for CAKUT. Here we show that the Esrrg protein is detected throughout early ureteric ducts as cytoplasmic/sub-membranous staining; with nuclear localization seen in developing nephrons. In 14.5-16.5 dpc (days post-conception) mouse embryos, Esrrg localizes to the subset of ductal tissue within the kidney, liver and lung. The renal ductal expression becomes localized to renal papilla by 18.5 dpc. Perturbation of function was performed in embryonic mouse kidney culture using pooled siRNA to induce knock-down and a specific small-molecule agonist to induce aberrant activation of Esrrg. Both resulted in severe abnormality of early branching events of the ureteric duct. Mouse embryos with a targeted inactivation of Esrrg on both alleles (Esrrg(-/-)) showed agenesis of the renal papilla but normal development of the cortex and remaining medulla. Taken together, these results suggest that Esrrg is required for early branching events of the ureteric duct that occur prior to the onset of nephrogenesis. These findings confirm ESRRG as a strong candidate gene for CAKUT.

A Systematic Review of Post-Work Core Temperature Cooling Rates Conferred by Passive Rest.

Physical work increases energy expenditure, requiring a considerable elevation of metabolic rate, which causes body heat production that can cause heat stress, heat strain, and hyperthermia in the absence of adequate cooling. Given that passive rest is often used for cooling, a systematic search of literature databases was conducted to identify studies that reported post-work core temperature cooling rates conferred by passive rest, across a range of environmental conditions. Data regarding cooling rates and environmental conditions were extracted, and the validity of key measures was assessed for each study. Forty-four eligible studies were included, providing 50 datasets. Eight datasets indicated a stable or rising core temperature in participants (range 0.000 to +0.028 °C min-1), and forty-two datasets reported reducing core temperature (-0.002 to -0.070 °C min-1) during passive rest, across a range of Wet-Bulb Globe Temperatures (WBGT). For 13 datasets where occupational or similarly insulative clothing was worn, passive rest resulted in a mean core temperature decrease of -0.004 °C min-1 (-0.032 to +0.013 °C min-1). These findings indicate passive rest does not reverse the elevated core temperatures of heat-exposed workers in a timely manner. Climate projections of higher WBGT are anticipated to further marginalise the passive rest cooling rates of heat-exposed workers, particularly when undertaken in occupational attire.

Positive body image, intuitive eating, and psychosocial functioning among older women: Testing an integrated model.

BACKGROUND: Research on the body image and eating behaviors of older women is scarce. Moreover, the scant existing research has lacked a focus on positive dimensions, such as positive reappraisal and acceptance, body appreciation, appearance satisfaction, and intuitive eating among older women. Therefore, the aim of the present study was to examine a model of the relationships among these positive dimensions and psychological functioning in older women. METHODS: A sample of 171 women aged 60-75 years were recruited through social media to respond to a survey assessing body image, eating behaviors, and psychological wellbeing. RESULTS: The final model was a good fit to the data. In this model, positive reappraisal and acceptance of age-related appearance changes was associated with higher body appreciation, in turn associated with higher body image related quality of life, higher levels of intuitive eating, and lower levels of depressive symptoms. CONCLUSION: Positive body image and positive reappraisal of aging-related changes in appearance are associated with psychological wellbeing among older women. Longitudinal data are needed to clarify the direction of these relationships and inform interventions. Body image remains an important dimension among older women and should be accounted for in broader health promotion efforts among this group.

Anticholinergic burden in older adult inpatients: patterns from admission to discharge and associations with hospital outcomes.

BACKGROUND: Anticholinergic medications are associated with adverse outcomes in older adults and should be prescribed cautiously. We describe the Anticholinergic Risk Scale (ARS) scores of older inpatients and associations with outcomes. METHODS: We included all emergency, first admissions of adults ⩾65 years old admitted to one hospital over 4 years. Demographics, discharge specialty, dementia/history of cognitive concern, illness acuity and medications were retrieved from electronic records. ARS scores were calculated as the sum of anticholinergic potential for each medication (0 = limited/none; 1 = moderate; 2 = strong and 3 = very strong). We categorised patients based on admission ARS score [ARS = 0 (reference); ARS = 1; ARS = 2; ARS ⩾ 3] and change in ARS score from admission to discharge [admission and discharge ARS = 0 (reference); same; decreased; increased]. We described anticholinergic prescribing patterns by discharge specialty and explored multivariable associations between ARS score categories and mortality using logistic regression [odds ratios (ORs), 95% confidence intervals (CIs)]. RESULTS: From 33,360 patients, 10,183 (31%) were prescribed an anticholinergic medication on admission. Mean admission ARS scores were: Cardiology and Stroke = 0.56; General Medicine = 0.78; Geriatric Medicine = 0.83; Other medicine = 0.81; Trauma and Orthopaedics = 0.66; Other Surgery = 0.65. Mean ARS did not increase from admission to discharge in any specialty but reductions varied significantly, from 4.6% (Other Surgery) to 27.7% (Geriatric Medicine) (p < 0.001). The odds of both 30-day inpatient and 30-day post-discharge mortality increased with admission ARS = 1 (OR = 1.21, 95% CI 1.01-1.44 and OR = 1.44, 1.18-1.74) but not with ARS = 2 or ARS ⩾ 3. The odds of 30-day post-discharge mortality were higher in all ARS change categories, relative to no anticholinergic exposure (same: OR = 1.45, 1.21-1.74, decreased: OR = 1.27, 1.01-1.57, increased: OR = 2.48, 1.98-3.08). CONCLUSION: The inconsistent dose-response associations with mortality may be due to confounding and measurement error which may be addressed by a prospective trial. Definitive evidence for this prevalent modifiable risk factor is required to support clinician behaviour-change, thus reducing variation in anticholinergic deprescribing by inpatient speciality. PLAIN LANGUAGE SUMMARY: We describe how commonly medicines which block the chemical acetylcholine are prescribed to older adults admitted to hospital as an emergency and explore links between these medicines and death during or soon after hospital admission Backgroud: Medicines which block the chemical acetylcholine are commonly prescribed to treat symptoms such as itch and difficulty sleeping or to treat medical conditions such as depression. However, some studies in older adults have found potential links between these medicines and confusion and falls. Therefore, doctors are recommended to prescribe these drugs cautiously in adults aged 65 years and over.Methods: In our paper we use data collected as part of routine medical care at one university hospital to describe how often these medicines are prescribed in a large sample of older adults admitted to hospital as an emergency. We look at the medicines patients are prescribed on admission to the hospital and also when they are later discharged.Results: We find that these medicines are frequently prescribed. We also find that, in general, patients are prescribed fewer of these potentially harmful medicines on hospital discharge compared with hospital admission. This suggests that clinicians are aware of advice to prescribe acetylcholine blocking medicines cautiously and they are more often stopped in hospital than started. However, we find a lot of variation in practice depending on which hospital specialty was caring for the patient during their inpatient stay. We also find potential links with these medicines and death during the admission or soon after hospital discharge, but these potential links are not always consistent.Conclusion: Further study is needed to fully understand links between medicines that block acetylcholine and late life health. This will be important to reduce variation in prescribing practices.
