Risk factors for older people re-presenting to the emergency department with falls: A case-control analysis.

OBJECTIVE: Falls are a leading cause for ED presentations among older adults. Existing secondary falls prevention interventions have not been shown to decrease fall-related ED re-presentation, indicating a need to better understand contributing factors. Our aim was to evaluate risk factors for fall re-presentations among the older patient population presenting to the ED. METHODS: This is a single-centre case-control study. Cases were patients aged ≥65 years with two falls-related ED presentations within 6 months. Age- and sex-matched controls had a corresponding index, but no subsequent ED fall presentation. Data collected included falls risk factors and clinical features of the index presentation. Univariate and multivariate analyses were conducted to assess the relationship between potential exposures and fall re-presentation. RESULTS: A total of 300 patients (mean age 83.8 years) were studied. On univariate analysis, factors significantly associated with ED fall re-presentation included increasing multimorbidity (P < 0.0001), increasing number of medications (P < 0.0001) and residing in residential aged care facility (RACF) (odds ratio [OR] 3.06, P < 0.001). No factors remained significant on multivariate analysis. Post-hoc analyses for the RACF subgroup showed that psychotropic medication use (OR 1.65, P = 0.04) and prior fall within 12 months (OR 2.68, P < 0.001) were significantly associated with re-presentation. Initial presentation with serious musculoskeletal injury was a significant protective factor (OR 0.21, P = 0.02). CONCLUSION: The present study failed to identify factors independently associated with ED fall re-presentation, suggesting that the factors are complex and inter-related. Two high-risk populations were identified - those from RACF and those initially presenting with falls not resulting in serious injury.

UnTWISTing the BALS: A study of predictive accuracy of clinical scoring tools for testicular torsion identification in adults.

OBJECTIVE: Testicular torsion is an uncommon but time-critical condition in EDs. If the diagnosis is missed or delayed, there are significant medicolegal and patient fertility implications. Scoring tools are advocated for use in children but have limited validation in adults. The aim of the present study was to explore the predictive accuracy of the testicular torsion scoring tools, Testicular Workup for Ischemia and Suspected Torsion (TWIST) and Boettcher Alert Score (BALS), in adult patients with a final ED diagnosis of torsion. METHODS: All patients with an ED working diagnosis of testicular torsion were identified retrospectively. Data collected from digital medical records included demographics, processes of care and clinical information. The outcome of interest was the predictive performance of the scores for a confirmed diagnosis of testicular torsion as adjudicated by an urologist or a surgeon. RESULTS: Fifty-four patients had complete clinical data, of whom 13 had confirmed torsion. The TWIST score had a high area under the receiver operating characteristics curve (AUROC) of 0.89 (95% confidence interval [CI] = 0.78-0.999) with a score of 6-7 corresponding to a positive predictive value (PPV) of 80% (95% CI = 38-96%). The BAL score had an AUROC of 0.79 (95% CI = 0.69-0.92). PPV for a score ≥2 was 38% (95% CI = 22-56%). CONCLUSION: A high TWIST score correlates to a high likelihood of torsion and can inform surgical decision-making in the absence of US.

The use of venous blood gas in assessing arterial acid-base and oxygenation status - an analysis of aggregated data from multiple studies evaluating the venous to arterial conversion (v-TAC) method.

BACKGROUND: Several methods exist to reduce the number of arterial blood gases (ABGs). One method, Roche v-TAC, has been evaluated in different patient groups. This paper aggregates data from these studies, in different patient categories using common analysis criteria. RESEARCH DESIGN AND METHODS: We included studies evaluating v-TAC based on paired arterial and peripheral venous blood samples. Bland-Altman analysis compared measured and calculated arterial values of pH, PCO2, and PO2. Subgroup analyses were performed for normal, chronic hypercapnia and chronic base excess, acute hyper- and hypocapnia, and acute and chronic base deficits. RESULTS: 811 samples from 12 studies were included. Bias and limits of agreement for measured and calculated values: pH 0.001 (-0.029 to 0.031), PCO2 -0.08 (-0.65 to 0.49) kPa, and PO2 0.04 (-1.71 to 1.78) kPa, with similar values for all sub-group analyses. CONCLUSION: These data suggest that v-TAC analysis may have a role in replacing ABGs, avoiding arterial puncture. Substantial data exist in patients with chronic hypercapnia and chronic base excess, acute hyper- and hypocapnia, and in patients with relatively normal acid-base status, with similar bias and precision across groups and across study data. Limited data exist for patients with acute and chronic base deficits.

Public toilets and their potential impact on an individual's health.

In modern society, people engage in social interactions and activities outside their own home. When in public settings people may need to eliminate bodily waste, so public toilets are required. Accessibility, availability and adaptability are essential principles for safe, private, and purposeful visits to public toilets. A diverse range of individuals use public toilets: various age profiles, all gender groups, vulnerable individuals and people with additional needs. Public toilets essentially need to be a place of privacy, safety and cleanliness to facilitate elimination of urine, evacuation of faeces, management of menstruation, and changing/disposing of continence wear products in a secure environment.

Carbapenemase gene blaOXA-48 detected at six freshwater sites in Northern Ireland discharging onto identified bathing locations.

Faecal contamination of surface waters has the potential to spread not only pathogenic organisms but also antimicrobial resistant organisms. During the bathing season of 2021, weekly water samples, from six selected coastal bathing locations (n = 93) and their freshwater tributaries (n = 93), in Northern Ireland (UK), were examined for concentrations of faecal indicator bacteria Escherichia coli and intestinal enterococci. Microbial source tracking involved detection of genetic markers from the genus Bacteroides using PCR assays for the general AllBac marker, the human HF8 marker and the ruminant BacR marker for the detection of human, and ruminant sources of faecal contamination. The presence of beta-lactamase genes blaOXA-48, blaKPC, and blaNDM-1 was determined using PCR assays for the investigation of antimicrobial resistance genes that are responsible for lack of efficacy in major broad-spectrum antibiotics. The beta-lactamase gene blaOXA-48 was found in freshwater tributary samples at all six locations. blaOXA-48 was detected in 83% of samples that tested positive for the human marker and 69% of samples that tested positive for the ruminant marker over all six locations. This study suggests a risk of human exposure to antimicrobial resistant bacteria where bathing waters receive at least episodically substantial transfers from such tributaries.

Characterization of HER2-low breast cancer in young women with germline BRCA1/2 pathogenetic variants: Results of a large international retrospective cohort study.

BACKGROUND: Breast cancer (BC) in women aged ≤40 years carrying germline pathogenetic variants (PVs) in BRCA1/2 genes is infrequent but often associated with aggressive features. Human epidermal growth factor receptor 2 (HER2)-low-expressing BC has recently emerged as a novel therapeutic target but has not been characterized in this rare patient subset. METHODS: Women aged ≤40 years with newly diagnosed early-stage HER2-negative BC (HER2-0 and HER2-low) and germline BRCA1/2 PVs from 78 health care centers worldwide were retrospectively included. Chi-square test and Student t-test were used to describe variable distribution between HER2-0 and HER2-low. Associations with HER2-low status were assessed with logistic regression. Kaplan-Meier method and Cox regression analysis were used to assess disease-free survival (DFS) and overall survival. Statistical significance was considered for p ≤ .05. RESULTS: Of 3547 included patients, 32.3% had HER2-low BC, representing 46.3% of hormone receptor-positive and 21.3% of triple-negative (TN) tumors. HER2-low vs. HER2-0 BC were more often of grade 1/2 (p < .001), hormone receptor-positive (p < .001), and node-positive (p = .003). BRCA2 PVs were more often associated with HER2-low than BRCA1 PVs (p < .001). HER2-low versus HER2-0 showed better DFS (hazard ratio [HR], 0.86; 95% CI, 0.76-0.97) in the overall population and more favorable DFS (HR, 0.78; 95% CI, 0.64-0.95) and overall survival (HR, 0.65; 95% CI, 0.46-0.93) in the TN subgroup. Luminal A-like tumors in HER2-low (p = .014) and TN and luminal A-like in HER2-0 (p = .019) showed the worst DFS. CONCLUSIONS: In young patients with HER2-negative BC and germline BRCA1/2 PVs, HER2-low disease was less frequent than expected and more frequently linked to BRCA2 PVs and associated with luminal-like disease. HER2-low status was associated with a modestly improved prognosis.

Incontinence and homelessness.

The fundamental principles of why specific people become homeless, can be grounded in a simple rationale or founded within sophisticated reasoning. For instance, people who suffer from substance abuse, addiction, alcohol, gambling, have mental health concerns or financial difficulties may be susceptible to homelessness. It is also identified that persons who experienced violence in their childhood or abuse by a partner are at a higher risk of becoming homeless. Homelessness knows no ethnic, cultural, religious or gender boundaries, and can impact all individuals' health and well-being. A health problem and worldwide phenomenon that affects all cohorts of the population, including the homeless, is urinary incontinence. The aim of this article is to increase the awareness of incontinence and highlight the impact it has on the lives of people that experience homelessness.

Incontinence-associated dermatitis in older adults in residential care settings: a point prevalence study.

Incontinence-associated dermatitis (IAD) is a skin inflammation caused by contact with urine or faeces or both. It has a negative effect on the patient's quality of life and is indicative of the care provided. However, globally there is a lack of empirical data on the prevalence of IAD. AIM: To identify, for the first time, the proportion of older adults in extended care settings in Ireland affected by IAD. DESIGN: Cross-sectional, multisite, point prevalence survey, across three community extended care settings for older people in Ireland. METHODS: Two clinical nurse specialists, using the Scottish Excoriation and Moisture Related Skin Damage Tool, identified the presence of IAD through clinical observation and visual skin inspection. IAD prevalence was calculated for the total population and incontinent population sets using percentages and confidence intervals (CI). RESULTS: The prevalence of incontinence was 86.4% (n=165), a significantly higher proportion were female (P=0.003). The point prevalence of IAD across the total population and incontinent population was 11.5% (22/191; 95% CI, 7.4-19.9%) and 13.3% (22/164; 95% CI, 8.5-19.5%), respectively. Being incontinent was associated with being female, more dependent (Barthel), having possible cognitive impairment, poorer mobility (Braden and Waterlow) and a high risk of pressure ulcers (Waterlow). A logistic regression analysis found no predictor variables for IAD among the variables that met the cut-off point for this analysis. CONCLUSIONS: The study provides the first point prevalence empirical data on the occurrence of IAD in Ireland. It can inform decision-making on future planning and budgeting of new quality improvement projects and act as a benchmark for ongoing auditing of IAD.

Predictive performance of the common red flags in emergency department headache patients: a HEAD and HEAD-Colombia study.

OBJECTIVES: Only a small proportion of patients presenting to an ED with headache have a serious cause. The SNNOOP10 criteria, which incorporates red and orange flags for serious causes, has been proposed but not well studied. This project aims to compare the proportion of patients with 10 commonly accepted red flag criteria (singly and in combination) between patients with and without a diagnosis of serious secondary headache in a large, multinational cohort of ED patients presenting with headache. METHODS: Secondary analysis of data obtained in the HEAD and HEAD-Colombia studies. The outcome of interest was serious secondary headache. The predictive performance of 10 red flag criteria from the SNNOOP10 criteria list was estimated individually and in combination. RESULTS: 5293 patients were included, of whom 6.1% (95% CI 5.5% to 6.8%) had a defined serious cause identified. New neurological deficit, history of neoplasm, older age (>50 years) and recent head trauma (2-7 days prior) were independent predictors of a serious secondary headache diagnosis. After adjusting for other predictors, sudden onset, onset during exertion, pregnancy and immune suppression were not associated with a serious headache diagnosis. The combined sensitivity of the red flag criteria overall was 96.5% (95% CI 93.2% to 98.3%) but specificity was low, 5.1% (95% CI 4.3% to 6.0%). Positive predictive value was 9.3% (95% CI 8.2% to 10.5%) with negative predictive value of 93.5% (95% CI 87.6% to 96.8%). CONCLUSION: The sensitivity and specificity of the red flag criteria in this study were lower than previously reported. Regarding clinical practice, this suggests that red flag criteria may be useful to identify patients at higher risk of a serious secondary headache cause, but their low specificity could result in increased rates of CT scanning.

Review article: Patients who leave before care is completed: What does the legal duty to warn mean for emergency department clinicians?

Patients leave ED for a variety of reasons and at all stages of care. In Australian law, clinicians and health services owe a duty of care to people presenting to the ED for care, even if they have not yet entered a treatment space. There is also a positive duty to warn patients of material risks associated with their condition, proposed treatment(s), reasonable alternative treatment options and the likely effect of their healthcare decisions, including refusing treatment. This extends to a decision to leave the ED before care is completed. The form of that warning may vary based on what is known about the patient's condition and the associated risks at the time. Specific documentation of warnings given is essential.

Expert United Kingdom consensus on the preservation of joint health in people with moderate and severe haemophilia A: A modified Delphi panel.

AIM: For people with haemophilia A (PwHA), bleeding in the joints leads to joint damage and haemophilia-related arthropathy, impacting range of motion and life expectancy. Existing guidelines for managing haemophilia A support healthcare professionals (HCPs) and PwHA in their efforts to preserve joint health. However, such guidance should be reviewed, considering emerging evidence and consensus as presented in this manuscript. METHODS: Fifteen HCPs experienced in the management of PwHA in the UK participated in a three-round Delphi panel. Consensus was defined at ≥70% of panellists agreeing or disagreeing for Likert-scale questions, and ≥70% selecting the same option for multiple- or single-choice questions. Questions not reaching consensus were revised for the next round. RESULTS: 26.8% (11/41), 44.8% (13/29) and 93.3% (14/15) of statements reached consensus in Rounds 1, 2 and 3, respectively. HCPs agreed that prophylaxis should be offered to patients with a baseline factor VIII (FVIII) level of ≤5 IU/dL and that, where there is no treatment burden, the aim of prophylaxis should be to achieve a trough FVIII level ≥15 IU/dL and maintain a longer period with FVIII levels of ≥20-30 IU/dL to provide better bleed protection. The aspirational goal for PwHA is to prevent all joint bleeds, which may be achieved by maintaining normalised (50-150 IU/dL) FVIII levels. CONCLUSION: The panel of experts were largely aligned on approaches to preserving joint health in PwHA, and this consensus may help guide HCPs.

"Putting the power back into community": A mixed methods evaluation of a chronic hepatitis B training course for the Aboriginal health workforce of Australia's Northern Territory.

BACKGROUND: Chronic hepatitis B (CHB) is endemic in the Aboriginal and Torres Strait Islander population of Australia's Northern Territory. Progression to liver disease can be prevented if holistic care is provided. Low health literacy amongst health professionals is a known barrier to caring for people living with CHB. We co-designed and delivered a culturally safe "Managing hepatitis B" training course for the Aboriginal health workforce. Here, we present an evaluation of the course. OBJECTIVES: 1. To improve course participants CHB-related knowledge, attitudes, and clinical practice. 2. To evaluate the "Managing hepatitis B" training course. 3. To enable participants to have the skills and confidence to be part of the care team. METHODS: We used participatory action research and culturally safe principles. We used purpose-built quantitative and qualitative evaluation tools to evaluate our "Managing hepatitis B" training course. We integrated the two forms of data, deductively analysing codes, grouped into categories, and assessed pedagogical outcomes against Kirkpatrick's training evaluation framework. RESULTS: Eight courses were delivered between 2019 and 2023, with 130 participants from 32 communities. Pre- and post-course questionnaires demonstrated statistically significant improvements in all domains, p<0.001 on 93 matched pairs. Thematic network analysis demonstrated high levels of course acceptability and significant knowledge acquisition. Other themes identified include cultural safety, shame, previous misinformation, and misconceptions about transmission. Observations demonstrate improvements in post-course engagement, a deep understanding of CHB as well as increased participation in clinical care teams. CONCLUSIONS: The "Managing hepatitis B" training course led to a sustained improvement in the knowledge and attitudes of the Aboriginal health workforce, resulting in improved care and treatment uptake for people living with CHB. Important non-clinical outcomes included strengthening teaching and leadership skills, and empowerment.

Undetected eating disorders among adolescent psychiatric inpatients.

AIM: The aim of this study was to identify the prevalence of undetected eating disorders (EDs) among adolescent psychiatric inpatients and to investigate the association between clinical, psychiatric, and sociocultural factors and EDs. METHODS: Between January and December 2018, patients aged 12-18 years, hospitalized for inpatient-level treatment were given the self-assessment questionnaires of the Eating Attitudes Test-26 (EAT-26), the Contour Drawing Figure Rating Scale (CDFRS), the Child Behaviour Check List, and Sociocultural Attitudes Toward Appearance Questionnaire-4 after their routine unstructured clinical diagnostic assessment on admission by a psychiatrist. Patients were reassessed after reviewing the psychometric assessment results. RESULTS: The prevalence of EDs among 117 psychiatric inpatients was 9.4%, all were female and all diagnosed with unspecified feeding and eating disorder. We showed that 63.6% of patients with EDs was diagnosed after the screening and not with the routine clinical interview. EAT-26 scores were weakly correlated with affective (r = 0.314, p = .001), anxious (r = 0.231, p = .012), somatic (r = 0.258, p = .005), and impulsive maladaptive behaviours (r = 0.272, p = .003). A formal ED diagnosis was positively associated with media pressure, (OR:1.660, 95% CI: 1.105-2.495) and oppositional defiance (OR: 1.391, 95% CI: 1.005-1.926), and negatively with conduct problems (OR: 0.695, 95% CI: 0.500-0.964). The CDFRS results were not different between the ED and non-ED groups. CONCLUSIONS: Our study suggests EDs remain a prevalent yet often overlooked diagnosis in adolescent psychiatric inpatients. Health care providers should screen for EDs in inpatient psychiatric settings as a part of routine assessment to improve the identification of disordered eating behaviours that often begin during adolescence.

Pregnancy After Breast Cancer in Young BRCA Carriers: An International Hospital-Based Cohort Study.

Importance: Young women with breast cancer who have germline pathogenic variants in BRCA1 or BRCA2 face unique challenges regarding fertility. Previous studies demonstrating the feasibility and safety of pregnancy in breast cancer survivors included limited data regarding BRCA carriers. Objective: To investigate cumulative incidence of pregnancy and disease-free survival in young women who are BRCA carriers. Design, Setting, and Participants: International, multicenter, hospital-based, retrospective cohort study conducted at 78 participating centers worldwide. The study included female participants diagnosed with invasive breast cancer at age 40 years or younger between January 2000 and December 2020 carrying germline pathogenic variants in BRCA1 and/or BRCA2. Last delivery was October 7, 2022; last follow-up was February 20, 2023. Exposure: Pregnancy after breast cancer. Main Outcomes and Measures: Primary end points were cumulative incidence of pregnancy after breast cancer and disease-free survival. Secondary end points were breast cancer-specific survival, overall survival, pregnancy, and fetal and obstetric outcomes. Results: Of 4732 BRCA carriers included, 659 had at least 1 pregnancy after breast cancer and 4073 did not. Median age at diagnosis in the overall cohort was 35 years (IQR, 31-38 years). Cumulative incidence of pregnancy at 10 years was 22% (95% CI, 21%-24%), with a median time from breast cancer diagnosis to conception of 3.5 years (IQR, 2.2-5.3 years). Among the 659 patients who had a pregnancy, 45 (6.9%) and 63 (9.7%) had an induced abortion or a miscarriage, respectively. Of the 517 patients (79.7%) with a completed pregnancy, 406 (91.0%) delivered at term (≥37 weeks) and 54 (10.4%) had twins. Among the 470 infants born with known information on pregnancy complications, 4 (0.9%) had documented congenital anomalies. Median follow-up was 7.8 years (IQR, 4.5-12.6 years). No significant difference in disease-free survival was observed between patients with or without a pregnancy after breast cancer (adjusted hazard ratio, 0.99; 95% CI, 0.81-1.20). Patients who had a pregnancy had significantly better breast cancer-specific survival and overall survival. Conclusions and Relevance: In this global study, 1 in 5 young BRCA carriers conceived within 10 years after breast cancer diagnosis. Pregnancy following breast cancer in BRCA carriers was not associated with decreased disease-free survival. Trial Registration: ClinicalTrials.gov Identifier: NCT03673306.

Parenteral Iron Therapy: Examining Current Evidence for Use in Athletes.

A high prevalence of iron deficiency exists in athlete populations. Various mechanisms, including increased losses through sweat, haemolysis, haematuria, and gastrointestinal micro-ischemia; inadequate dietary intake; and transient exercise-induced increases in the regulatory hormone, hepcidin, contribute to the increased prevalence in athletes. Indeed, hepcidin has been shown to peak around 3-6 hours post-exercise, limiting iron absorption from the gut. As the practitioner's ability to control losses is limited, the key to treatment of iron deficiency in athletes is optimal timing of dietary and oral iron supplementation around these periods of reduced gut absorption. While timing and dosing schedule strategies might be sufficient to treat iron deficiency non-anaemia, the significant lag to impact iron status is relatively long. Therefore, in iron deficiency anaemia, the use of parenteral iron has the benefit of rapid repletion of iron stores and normalisation of haemoglobin status, while bypassing the action of hepcidin at the gut. Furthermore, newer intravenous formulations can be administered as a single total dose over 15-60 min and have a similar safety profile to oral treatment. This review discusses the existing evidence for parenteral iron use in athletes and the unique context for consideration when choosing the parenteral route in this population.

Update on the management of first episode primary spontaneous pneumothorax in an Australian hospital network.

International guidelines and recent research favour a less interventional approach to primary spontaneous pneumothorax (PSP). A retrospective clinical audit of 68 first-episode PSP was undertaken at a major tertiary teaching hospital network in Melbourne, Australia, found that most patients presenting with a moderate to large pneumothorax received initial intercostal catheter insertion (56%), though many (81%) would have met criteria for consideration of conservative management. The results suggest continued deviation from clinical guidelines in the management of PSP.

Measuring ovarian toxicity in clinical trials: an American Society of Clinical Oncology research statement.

Anticancer agents can impair ovarian function, resulting in premature menopause and associated long-term health effects. Ovarian toxicity is not usually adequately assessed in trials of anticancer agents, leaving an important information gap for patients facing therapy choices. This American Society of Clinical Oncology (ASCO) statement provides information about the incorporation of ovarian toxicity measures in trial design. ASCO recommends: (1) measurement of ovarian toxicity in relevant clinical trials of anticancer agents that enrol post-pubertal, pre-menopausal patients; (2) collection of ovarian function measures at baseline and at 12-24 months after anticancer agent cessation, as a minimum, and later in line with the trial schedule; and (3) assessment of both clinical measures and biomarkers of ovarian function. ASCO recognises that routine measurement of ovarian toxicity and function in cancer clinical trials will add additional complexity and burden to trial resources but asserts that this issue is of such importance to patients that it cannot continue to be overlooked.

A holistic approach to assessing an individual with urinary incontinence.

Urinary incontinence can have an overwhelmingly negative impact on an individual's quality of life. The personal, physical, psychosocial and sexual implications of urinary incontinence can affect health and well-being. This can increase the risk of falls, depression, anxiety, social isolation alongside a greater need for long-term care from a individual's own home. Statically, the prevalence rates of urinary incontinence increases with age; however, incontinence is not an inevitable or acceptable part of ageing-symptoms can be improved and managed effectively for suffers of this common condition. Urinary incontinence can be challenging to assess, address and overcome for individuals. However health professionals need to have the expertise and experience to undertake a comprehensive continence assessment. When assessment is completed evidence-based interventions can be recommended, implemented and subsequently evaluated.
