RESUMEN
The Eukaryotic Pathogen, Vector and Host Informatics Resource (VEuPathDB, https://veupathdb.org) represents the 2019 merger of VectorBase with the EuPathDB projects. As a Bioinformatics Resource Center funded by the National Institutes of Health, with additional support from the Welllcome Trust, VEuPathDB supports >500 organisms comprising invertebrate vectors, eukaryotic pathogens (protists and fungi) and relevant free-living or non-pathogenic species or hosts. Designed to empower researchers with access to Omics data and bioinformatic analyses, VEuPathDB projects integrate >1700 pre-analysed datasets (and associated metadata) with advanced search capabilities, visualizations, and analysis tools in a graphic interface. Diverse data types are analysed with standardized workflows including an in-house OrthoMCL algorithm for predicting orthology. Comparisons are easily made across datasets, data types and organisms in this unique data mining platform. A new site-wide search facilitates access for both experienced and novice users. Upgraded infrastructure and workflows support numerous updates to the web interface, tools, searches and strategies, and Galaxy workspace where users can privately analyse their own data. Forthcoming upgrades include cloud-ready application architecture, expanded support for the Galaxy workspace, tools for interrogating host-pathogen interactions, and improved interactions with affiliated databases (ClinEpiDB, MicrobiomeDB) and other scientific resources, and increased interoperability with the Bacterial & Viral BRC.

OBJECTIVES: The objective of this study was to examine the patient characteristics and features associated with the initial rehabilitation utilization with a particular emphasis on outpatient rehabilitation after total knee arthroplasty (TKA) among 2016-2018 Texas Medicare enrollees. DESIGN: This is a retrospective cohort study. We used chi-square tests to examine the variability in patient demographic and clinical characteristics across the different post-acute rehabilitation settings after TKA. A Cochran-Armitage trend test was used to investigate the yearly trend of outpatient rehabilitation utilization after TKA. SETTING: Post-acute rehabilitation settings after TKA. PARTICIPANTS: The target population was Medicare beneficiaries aged ≥65 with an initial TKA in 2016-2018 and complete demographic and residential information (N=44,313). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We identified whether patients first used (1) outpatient rehabilitation, (2) home health, (3) self-care, (4) inpatient rehabilitation, (5) skilled nursing, or (6) other setting within the 3 months after TKA. RESULTS: Our results demonstrated an increasing use of the initial outpatient rehabilitation and home health, while the use of skilled nursing and inpatient rehabilitation facilities decreased from 2016 to 2018. The increase in outpatient utilization was significant in 2018 compared with 2016 controlling for distance to the TKA facilities, comorbid conditions, sex, race/ethnicity groups (White, Black, Hispanic, and Others), lower income (Medicaid eligible), Medicare entitlement types, age groups, and rurality (OR 1.23, 95% CI 1.12-1.34). However, the overall utilization rate of the initial outpatient rehabilitation after TKA remained low, increasing from 7.36% in 2016 to 8.60% in 2018. CONCLUSION: Despite the growing use of the initial outpatient rehabilitation after TKA, the overall rate of outpatient rehabilitation utilization remained low. Our findings raise an important question as to whether certain patient demographics and clinical groups might have limited access to outpatient rehabilitation after TKA.

PURPOSE: The purpose of this systematic review was to summarize recent evidence on the efficacy of behavioral interventions for the management of urinary incontinence (UI) among women in nursing homes. METHODS: Systematic review of the literature. For this review, behavioral interventions were defined as those that included some form of physical exercise or behavior modification such as scheduled toileting. SEARCH STRATEGY: A search of MEDLINE/PubMed, CINAHL, Scopus, and Cochrane Library electronic databases was conducted seeking randomized controlled trials published since 2010 in female participants residing in long-term care facilities (nursing homes, skilled nursing facilities) and diagnosed with UI. Inclusion criteria were studies that addressed the effects of voiding regimens, lower extremity strengthening, functional training, food and fluid management, and pelvic floor muscle training. Independent reviewers extracted relevant data and assessed methodological quality using the PEDro scale. FINDINGS: Five studies (pooled sample, N = 399) met inclusion criteria; mean age of participants was 81.1 ± 6.8 years; 85% were female. The PEDro scores ranged from 6 to 9; only 2 studies included residents with cognitive impairment. Interventions included voiding strategies, increasing physical activity, functional mobility training, pelvic floor muscle training, fluid management, and multicomponent combinations of approaches. Three of the 5 studies were multicomponent interventions and 2 focused on a single intervention. Outcomes included objective measures of incontinent episodes and subjective assessments of UI severity. CONCLUSIONS: Behaviorally based interventions can be successful in improving UI among nursing residents with and with no cognitive impairment. IMPLICATIONS: Future studies should examine logistic and labor costs associated with sustaining behavioral interventions using nursing home staff and investigate the effects of these therapies using appropriate quality-of-life metrics for this population.

BACKGROUND: Ocular conditions are common following stroke and frequently occur in combination with pre-existing ophthalmologic disease. The Medicare International Statistical Classification of Diseases and Related Health Problems (ICD-10) coding system for identifying vision related health conditions provides a much higher level of detail for coding these complex scenarios than the previous ICD-9 system. While this new coding system has advantages for clinical care and billing, the degree to which providers and researchers are utilizing the expanded code structure is unknown. The purpose of this study was to describe the use of ICD-10 vision codes in a large cohort of stroke survivors. METHODS: Retrospective cohort design to study national 100% Medicare claims files from 2015 through 2017. Descriptive data analyses were conducted using all available ICD-10 vision codes for beneficiaries who had an acute care stay because of a new stroke. The outcome of interest was ≥1 ICD-10 visual code recorded in the claims chart. RESULTS: The cohort (n = 269,314) was mostly female (57.1%) with ischemic stroke (87.8%). Approximately 15% were coded as having one or more ocular condition. Unspecified glaucoma was the most frequently used code among men (2.83%), those over 85+ (4.80%) and black beneficiaries (4.12%). Multiple vision codes were used in few patients (0.6%). Less than 3% of those in the oldest group (85+ years) had two or more vision codes in their claims. CONCLUSIONS: Ocular comorbidity was present in a portion of this cohort of stroke survivors, however the vision codes used to describe impairments in this population were few and lacked specificity. Future studies should compare ophthalmic examination results with billing codes to characterize the type and frequency of ocular comorbidity. It important to understand how the use of ICD-10 vision codes impacts clinical decision making, recovery, and outcomes.

Transcriptomic, metabolomic, physiological, and computational modeling approaches were integrated to gain insight into the mechanisms of antibiotic tolerance in an in vitro biofilm system. Pseudomonas aeruginosa biofilms were grown in drip flow reactors on a medium composed to mimic the exudate from a chronic wound. After 4 days, the biofilm was 114 µm thick with 9.45 log10 CFU cm-2 These biofilms exhibited tolerance, relative to exponential-phase planktonic cells, to subsequent treatment with ciprofloxacin. The specific growth rate of the biofilm was estimated via elemental balances to be approximately 0.37 h-1 and with a reaction-diffusion model to be 0.32 h-1, or one-third of the maximum specific growth rate for planktonic cells. Global analysis of gene expression indicated lower transcription of ribosomal genes and genes for other anabolic functions in biofilms than in exponential-phase planktonic cells and revealed the induction of multiple stress responses in biofilm cells, including those associated with growth arrest, zinc limitation, hypoxia, and acyl-homoserine lactone quorum sensing. Metabolic pathways for phenazine biosynthesis and denitrification were transcriptionally activated in biofilms. A customized reaction-diffusion model predicted that steep oxygen concentration gradients will form when these biofilms are thicker than about 40 µm. Mutant strains that were deficient in Psl polysaccharide synthesis, the stringent response, the stationary-phase response, and the membrane stress response exhibited increased ciprofloxacin susceptibility when cultured in biofilms. These results support a sequence of phenomena leading to biofilm antibiotic tolerance, involving oxygen limitation, electron acceptor starvation and growth arrest, induction of associated stress responses, and differentiation into protected cell states.IMPORTANCE Bacteria in biofilms are protected from killing by antibiotics, and this reduced susceptibility contributes to the persistence of infections such as those in the cystic fibrosis lung and chronic wounds. A generalized conceptual model of biofilm antimicrobial tolerance with the following mechanistic steps is proposed: (i) establishment of concentration gradients in metabolic substrates and products; (ii) active biological responses to these changes in the local chemical microenvironment; (iii) entry of biofilm cells into a spectrum of states involving alternative metabolisms, stress responses, slow growth, cessation of growth, or dormancy (all prior to antibiotic treatment); (iv) adaptive responses to antibiotic exposure; and (v) reduced susceptibility of microbial cells to antimicrobial challenges in some of the physiological states accessed through these changes.

PURPOSE OF REVIEW: The treatment of debilitating pain and loss of function secondary to lumbar stenosis is in high demand with the aging patient population. Options, including epidural steroid injections (ESIs) and medication therapy, are limited and it is unclear if they provide any functional improvements. In this prospective study, we evaluate functional outcomes in older adults with symptomatic lumbar stenosis treated with ESIs compared to those managed with medications by introducing the Short Physical Performance Battery (SPPB). Our study was IRB-approved and included 16 patients, 68 to 83 years old, with symptomatic back and radicular leg pain secondary to lumbar stenosis. Patients could elect to undergo a lumbar ESI (n = 11) or be treated via medication management (n = 5). Numeric pain score, SPPB score, and adverse events were measured and compared at baseline and a 1-month follow-up visit. RECENT FINDINGS: Statistically significant improvements were observed from baseline compared to the 1-month follow-up for total SPPB score in the injection group. Similar improvements in the injection group were observed for pain scores and the SPPB subcomponents such as the 4-m walk test, chair stand time, and balance score. Comparatively, no statistically significant improvements were observed in the medication group. Lumbar ESIs improved objective physical capacity parameters and pain scores in elderly patients with symptomatic lumbar stenosis compared to medication management. In addition, the SPPB is an easy-to-use tool to measure changes in physical function in older adults and could easily be integrated into an outpatient pain clinic.

BACKGROUND: Clostridium difficile, a spore-forming Gram-positive anaerobic bacillus, is the most common causative agent of healthcare-associated diarrhoea. Formation of biofilms may protect C. difficile against antibiotics, potentially leading to treatment failure. Furthermore, bacterial spores or vegetative cells may linger in biofilms in the gut causing C. difficile infection recurrence. OBJECTIVES: In this study, we evaluated and compared the efficacy of four antibiotics (fidaxomicin, surotomycin, vancomycin and metronidazole) in penetrating C. difficile biofilms and killing vegetative cells. METHODS: C. difficile biofilms grown initially for 48 or 72 h using the colony biofilm model were then treated with antibiotics at a concentration of 25 × MIC for 24 h. Vegetative cells and spores were enumerated. The effect of treatment on biofilm structure was studied by scanning electron microscopy (SEM). The ability of fidaxomicin and surotomycin to penetrate biofilms was studied using fluorescently tagged antibiotics. RESULTS: Both surotomycin and fidaxomicin were significantly more effective than vancomycin or metronidazole (P < 0.001) at killing vegetative cells in established biofilms. Fidaxomicin was more effective than metronidazole at reducing viable spore counts in biofilms (P < 0.05). Fluorescently labelled surotomycin and fidaxomicin penetrated C. difficile biofilms in <â1 h. After 24 h of treatment, SEM demonstrated that both fidaxomicin and surotomycin disrupted the biofilm structure, while metronidazole had no observable effect. CONCLUSIONS: Fidaxomicin is effective in disrupting C. difficile biofilms, killing vegetative cells and decreasing spore counts.

OBJECTIVE: To examine how similar summary scores of physical functioning using the FIM can represent different patient clinical profiles. DESIGN: Retrospective cohort study. SETTING: Inpatient rehabilitation facilities. PARTICIPANTS: Medicare fee-for-service beneficiaries (N=765,441) discharged from inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We used patients' scores on items of the FIM to quantify their level of independence on both self-care and mobility domains. We then identified patients as requiring "no physical assistance" at discharge from inpatient rehabilitation by using a rule and score-based approach. RESULTS: In those patients with FIM self-care and mobility summary scores suggesting no physical assistance needed, we found that physical assistance was in fact needed frequently in bathroom-related activities (eg, continence, toilet and tub transfers, hygiene, clothes management) and with stairs. It was not uncommon for actual performance to be lower than what may be suggested by a summary score of those domains. CONCLUSIONS: Further research is needed to create clinically meaningful descriptions of summary scores from combined performances on individual items of physical functioning.

Monitoring patients with burn wounds for infection is standard practice because failure to rapidly and specifically identify a pathogen can result in poor clinical outcomes, including death. Therefore, a method that facilitates detection and identification of pathogens in situ within minutes of biopsy would be a significant benefit to clinicians. Mass spectrometry is rapidly becoming a standard tool in clinical settings, capable of identifying specific pathogens from complex samples. Imaging mass spectrometry (IMS) expands the information content by enabling spatial resolution of biomarkers in tissue samples as in histology, without the need for specific stains/antibodies. Herein, a murine model of thermal injury was used to study infection of burn tissue by Pseudomonas aeruginosa. This is the first use of IMS to detect P. aeruginosa infection in situ from thermally injured tissue. Multiple molecular features could be spatially resolved to infected or uninfected tissue. This demonstrates the potential use of IMS in a clinical setting to aid doctors in identifying both presence and species of pathogens in tissue.

BACKGROUND: Conducting 5 A's counseling in clinic and utilizing technology-based resources are recommended to promote physical activity but little is known about how to implement such an intervention. This investigation aimed to determine the feasibility and acceptability, using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework, of a pragmatic, primary care-based intervention that incorporated 5 A's counseling and self-control through an activity monitor. METHODS: Primary care patients (n = 40) 55-74 years of age were recruited and randomized to receive a pedometer or an electronic activity monitor (EAM), Jawbone UP24, to monitor activity for 12 weeks. Participants were also invited to a focus group after completing the intervention. Stakeholders (n = 36) were recruited to provide feedback. RESULTS: The intervention recruitment rate was 24.7%. The attrition rate was 20% with a significantly higher rate for the pedometer group (p = 0.02). The EAM group increased their minutes of physical activity by 11.1 min/day while the pedometer maintained their activity (0.2 min/day), with no significant group difference. EAM participants liked using their monitor and would continue wearing it while the pedometer group was neutral to these statements (p < 0.05). Over the 12 weeks there were 490 comments and 1094 "likes" given to study peers in the corresponding application for the UP24 monitor. Some EAM participants enjoyed the social interaction feature while others were uncomfortable talking to strangers. Participants stated they would want counseling from a counselor and not their physician or a nurse. Other notable comments included incorporating multiple health behaviors, more in-person counseling with a counselor, and having a funding source for sustainability. CONCLUSIONS: Overall, the study was well-received but the results raise a number of considerations. Practitioners, counselors, and researchers should consider the following before implementing a similar intervention: 1) utilize PA counselors, 2) target multiple health behaviors, 3) form a social support group, 4) identify a funding source for sustainability, and 5) be mindful of concerns with technology.

Orthopaedic device-related infections are closely linked to biofilm formation on the surfaces of these devices. Several modified titanium (Ti-6Al-4V) surfaces doped with fluorine were studied in order to evaluate the influence of these modifications on biofilm formation by Gram-positive and Gram-negative bacteria as well as a yeast. The biofilm studies were performed according to the standard test method approved by ASTM (Designation: E2196-12) using the Rotating Disk Reactor. Four types of Ti-6Al-4V samples were tested; chemically polished (CP), two types of nanostructures containing fluorine, nanoporous (NP) and nanotubular (NT), and non-nanostructured fluorine containing samples (fluoride barrier layers, FBL). Different species of Gram-positive cocci, (Staphylococcus aureus and epidermidis), Gram-negative rods (Escherichia coli, Pseudomonas aeruginosa), and a yeast (Candida albicans) were studied. For one of the Gram-positive (S. epidermidis) and one of the Gram-negative (E. coli) species a statistically-significant decrease in biofilm accumulation for NP and NT samples was found when compared with the biofilm accumulation on CP samples. The results suggest an effect of the modified materials on the biofilm formation.

OBJECTIVE: To compare the 30-day readmission predictive power of in-hospital walking activity and in-hospital activities of daily living (ADLs) in older acutely ill patients. In addition, we sought to identify preliminary walking thresholds that could support the targeting of interventions aimed at minimizing rehospitalizations. DESIGN: Prospective, observational clinical cohort study. Step counts during hospitalization were assessed via accelerometry. ADL function was assessed within 48 hours of admission. SETTING: Acute care hospital. PARTICIPANTS: One hundred sixty-four ambulatory persons aged 65 years and older admitted to the hospital from the community with an acute medical illness. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Readmission back to the index hospital (yes vs no) within 30 days of discharge. RESULTS: Twenty-six patients (15.8%) were readmitted within 30 days of discharge. Walking activity during hospitalization was more strongly and significantly associated with 30-day readmission (odds ratio=0.90; 95% confidence interval, 0.82-0.98) than ADL function (odds ratio=0.45; 95% confidence interval, 0.14-1.45) after adjusting for relevant readmission risk factors. The predictive accuracy (area under the curve) was highest for models that included walking activity and changed little with the addition of ADLs. A walking threshold of 275 steps or more per day identified patients at reduced 30-day readmission risk. CONCLUSIONS: Walking activity was a stronger predictor of readmission than ADLs. Monitoring patient activity during hospitalization may provide clinicians with valuable information on early readmission risk not captured by measures of ADLs. Further study is needed to replicate these findings and monitor walking activity posthospitalization to further advance our understanding of readmission risk.

Bacterial biofilm formation is a complex developmental process involving cellular differentiation and the formation of intricate 3D structures. Here we demonstrate that exposure to ferric chloride triggers rugose biofilm formation by the uropathogenic Escherichia coli strain UTI89 and by enteric bacteria Citrobacter koseri and Salmonella enterica serovar typhimurium. Two unique and separable cellular populations emerge in iron-triggered, rugose biofilms. Bacteria at the air-biofilm interface express high levels of the biofilm regulator csgD, the cellulose activator adrA, and the curli subunit operon csgBAC. Bacteria in the interior of rugose biofilms express low levels of csgD and undetectable levels of matrix components curli and cellulose. Iron activation of rugose biofilms is linked to oxidative stress. Superoxide generation, either through addition of phenazine methosulfate or by deletion of sodA and sodB, stimulates rugose biofilm formation in the absence of high iron. Additionally, overexpression of Mn-superoxide dismutase, which can mitigate iron-derived reactive oxygen stress, decreases biofilm formation in a WT strain upon iron exposure. Not only does reactive oxygen stress promote rugose biofilm formation, but bacteria in the rugose biofilms display increased resistance to H(2)O(2) toxicity. Altogether, we demonstrate that iron and superoxide stress trigger rugose biofilm formation in UTI89. Rugose biofilm development involves the elaboration of two distinct bacterial populations and increased resistance to oxidative stress.

OBJECTIVES: To classify hospitalized older patients with slow gait speed, and test the hypothesis that slow gait speed or dismobility is associated with increased mortality risk. DESIGN: Prospective study. SETTING: Acute care geriatric hospital unit. PARTICIPANTS: Older patients (N=289) admitted to a geriatric hospital unit. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Two-year survival determined by medical record review and a search of the National Death Index. RESULTS: Most of the older patients were women (61.6%) and non-Hispanic white (72.3%). A total of 213 older patients (73.7%) had gait speeds ≤0.6 m/s and were classified with dismobility; 17% (49/289) of the sample died during the 2-year follow-up. All but 5 deaths occurred in older patients with dismobility. Older patients with dismobility were more than 2.5 times as likely to die than those with gait speeds >.60 m/s (hazard ratio, 2.60; 95% confidence interval, 1.01-6.77), after adjusting for age, sex, race/ethnicity, and comorbidity. CONCLUSIONS: A simple and quick screen for gait speed was evaluated in this study of hospitalized older patients. A clinical classification of dismobility could provide the inpatient health care team with meaningful information about the older patients' underlying health conditions and future prognosis, and provides an opportunity to discuss and implement treatment options with patients and their families.

PURPOSE: This case report describes a simple means of estimating energy costs for a child with cerebral palsy using different assistive devices within a school setting. KEY POINTS: A 9-year-old boy, Gross Motor Function Classification Scale level III, was assessed over 8 ambulation trials using a posterior walker and using forearm crutches. Each trial was followed by a fine motor accuracy task. An energy expenditure index (EEI) was calculated for each device. For the posterior walker, EEI was 47% higher overall compared with forearm crutches. Fine motor accuracy and task completion time were similar for both devices. CONCLUSION: EEI was a straightforward method of estimating the energy costs of different assistive devices. Measurement procedures described in this case were time efficient in the field and provided a reasonable estimation of energy expenditure to help decide objectively which assistive device would best fit the needs of the student.

Using Bronfenbrenner's ecological systems model, this study examined allegations of elder abuse made to Kentucky Adult Protective Services (APS) and the investigation that followed, in order to understand how APS addressed the needs of abused elders. Elder abuse allegations made to APS during the study week were collected using 3 study tools. Allegations and resulting investigations were analyzed. During the study week, APS received 1,002 calls alleging elder abuse. Of these, 483 were categorized as reports needing protective services, with 177 reports screened in for investigation and 167 actually investigated. Results describe characteristics of abuse calls, investigations, victims, perpetrators, and total investigation times. Substantiation ratio, recidivism, and whether investigation increased or decreased the risk of abuse were also assessed. An examination of APS casework through the lens of nested systems frames the study findings and discussion. Such an examination has the potential to improve the quality of services provided to older adults.

CONTEXT: Previous research has demonstrated that using a multicomponent approach to ankle injury preventions can significantly reduce ankle injuries; however, these studies lack specific intervention recommendations. OBJECTIVE: To evaluate the exercise components of prevention programs on ankle injuries specifically in high school athletes. Secondary objectives were to assess the overall effectiveness of prevention programs on ankle injuries in this population and how compliance and education may impact success. DATA SOURCES: A total of 5 databases were searched through September 26, 2022. STUDY SELECTION: Study inclusion criteria included randomized control trials (RCTs) investigating exercise interventions in high school athletes aged 13 to 19 years, participation in sports competition, reporting of injury incidence, and specific exercise interventions used. STUDY DESIGN: Systematic review and meta-analysis. LEVEL OF EVIDENCE: Level 1. DATA EXTRACTION: Pooled overall ankle injury incidence rate ratio and 95% CIs were calculated using random-effects meta-analysis. RESULTS: A total of 10 studies were included, of which 9 used multicomponent exercise interventions and 1 used only balance training. Of the 10 studies, 3 demonstrated statistically significant reduction in ankle injuries. When data from all 10 studies were pooled and analyzed, there was a statistically significant overall reduction (incidence rate ratio, 0.74; 95% CI 0.60-0.91) in ankle injuries when comparing intervention groups with controls. CONCLUSION: The most effective injury prevention programs included multiple components, emphasized strengthening and agility exercises, and promoted high adherence to the intervention. The importance of coach and player education on how and why to perform an injury prevention program as well as the frequency and duration of programs was also important. Exercise-based injury prevention programs may reduce ankle injury incidence in youth athletes by 26% when pooling data from a multitude of sport types/settings.
RESUMEN
BACKGROUND: Untreated, urgency urinary incontinence (UUI) and overactive bladder (OAB) can precipitate a vicious cycle of decreasing physical activity, social isolation, fear of falling, and falls. Structured behavioral interventions and medications are common initial treatment options, but they elicit their effects through very different mechanisms of action that may influence fall-related outcomes differently. This study will determine the feasibility of conducting a comparative effectiveness, three-arm, mixed methods, randomized clinical trial of a behaviorally based pelvic floor muscle training (PFMT) intervention versus two recent drug options in older women with UUI or OAB who are also at increased risk of falling. METHODS: Forty-eight women 60 years and older with UUI or OAB who screen positive for increased fall risk will be recruited through the urogynacology and pelvic health clinics of our university health system. Participants will be randomly assigned to one of three 12-week treatment arms: (1) a course of behavioral and pelvic floor muscle training (PFMT) provided by physical therapists; (2) the beta-3 agonist, mirabegron; and (3) the antimuscarinic, trospium chloride. Study feasibility will be established through objective metrics of evaluability, adherence to the interventions, and attrition. We will also assess relevant measures of OAB symptom severity, quality of life, physical activity, incident falls, and concern about falling. DISCUSSION: The proposed research seeks to ultimately determine if linkages between reduction in UI symptoms through treatment also reduce the risk of falling in this patient population. TRIAL REGISTRATION: NCT05880862. Registered on 30 May 2023.
RESUMEN
IMPORTANCE: Overactive bladder (OAB) syndrome and urinary incontinence, age, and comorbid burden are strong risk factors for falls in women. Less is known about their cumulative effects on fall risk in a urogynecologic population. OBJECTIVE: The purpose of this study was to investigate the effects of coexisting OAB, older age, and comorbidities on risk of falling among treatment seeking women with pelvic floor disorders. STUDY DESIGN: We conducted a retrospective medical records review of 348 consecutive women presenting to a urogynecology clinic over 6 months. Fall risk was determined by the Centers for Disease Control and Prevention's, Stopping Elderly Accidents, Deaths, and Injuries screening tool. Clinical and sociodemographic measures were abstracted from the electronic medical record. Odds of screening positive for high fall risk based on different patient profiles were calculated. We then used a classification and regression tree analysis to determine the relative importance of the different variables on fall risk within the homogeneous subgroups. RESULTS: Of the 348 women (mean age, 58.7 ± 15.8 years) who completed the fall risk screen, 124 (36%) screened positive for increased fall risk. Overactive bladder symptoms increased the likelihood of a positive fall risk screen across all combinations of age and comorbid burden. The patient profile of ≥3 OAB symptoms, ≥4 comorbid conditions, and age 65 years or older increased the odds of screening positive for high fall risk more than 6-fold (odds ratio, 6.4; 95% confidence interval, 3.1-12.9). In the following order of importance, the combination of high comorbid burden, OAB, and older age identified approximately 3 in 4 patients (73.3%) at high risk of falling. CONCLUSION: The presence of 3 easily identifiable patient characteristics is strongly associated with a risk of falls in women seeking care for pelvic floor disorders.

OBJECTIVES: The objective of this study was to determine the prevalence of increased fall risk among women presenting to a large pelvic health center using a screening method compatible with the busy clinic environment and to identify factors associated with increased risk. METHODS: A retrospective medical records review was conducted on consecutive treatment-seeking women presenting to a Urogynecology & Pelvic Health Center over 6 months. The Centers for Disease Control and Prevention, Stopping Elderly Accidents, Deaths, and Injuries fall risk screening tool was included among the intake questionnaires all patients completed before their scheduled appointments. Relevant sociodemographic and clinical measures were abstracted from the electronic medical record. RESULTS: Three hundred and forty-eight women completed the fall screen. One hundred and twenty-four (36%) screened positive for increased fall risk. Mean age was 58.7 ± 15.8 years. An age threshold of 68 years best discriminated between those who were and were not identified as at risk. There was a gradient of association between number of urinary symptoms and prevalence of increased fall risk. Patients with 3 or more urinary symptoms were most likely to screen positive (1: odds ratio [OR], 1.51 [0.86-2.66]; 2: OR, 1.62 [0.99-2.64]; 3 or more: OR, 1.84 [1.07-3.17]) after adjusting for other know fall risk factors. CONCLUSIONS: The prevalence of increased fall risk in this patient population is high and highest in women with multiple urinary symptoms. The Stopping Elderly Accidents, Deaths, and Injuries screening tool was a feasible and nonintrusive screening method for identifying increased fall risk during routine patient care. Fall risk and concern about falling should be taken into consideration when deciding management strategies for urinary problems.
