Longitudinal profiles of the vaginal microbiota of pre-, peri-, and postmenopausal women: preliminary insights from a secondary data analysis.

OBJECTIVE: Menopause is often accompanied by lowered Lactobacillus spp. relative abundance and increased abundance of diverse anaerobic/aerobic bacteria in the vaginal microbiota due in part to declines in estrogen. These microbiota are associated with urogenital symptoms and infections. In premenopause, vaginal microbiota can fluctuate rapidly, particularly with menstrual cycles and sexual activity; however, the longitudinal dynamics of vaginal microbiota are understudied in peri- and postmenopause. We described vaginal community stability across reproductive stages. METHODS: Pre- (n = 83), peri- (n = 8), and postmenopausal (n = 11) participants provided twice-weekly mid-vaginal samples (total, 1,556; average, 15 per participant) over 8 weeks in an observational study. Composition of the vaginal microbiota was characterized by 16S rRNA gene amplicon sequencing, and a community state type (CST) was assigned to each sample. Clustering of longitudinal CST profiles, CST transition rates, duration of low-Lactobacillus/high bacterial diversity CSTs, and other metrics of bacterial community dynamics were assessed across reproductive stages. RESULTS: The proportion of participants with longitudinal CST profiles characterized by low-Lactobacillus CSTs was similar among pre- (38.6%), peri- (37.5%), and postmenopausal (36.4%) participants (P = 0.69). CST transition rates between consecutive samples were 21.1%, 16.7%, and 14.6% for pre-, peri-, and postmenopausal participants, respectively (P = 0.49). Low-Lactobacillus CST tended to persist for at least 4 weeks, irrespective of reproductive stage. CONCLUSIONS: Findings from this small yet frequently sampled cohort revealed vaginal bacterial fluctuations over 8 weeks that were similar across reproductive stages. Larger and longer-term studies based on these preliminary data could provide insights into the influence of microbiota dynamics on urogenital outcomes during menopause.

Report of similar placebo response in one internet versus onsite randomised controlled trials from the literature.

Objective: The aim of this study was to compare the magnitude and the predictors of the placebo response in an internet versus onsite randomised controlled trials (RCTs) in people with hand osteoarthritis (HOA). Method: This study is a post-hoc analysis based on one internet RCT (RADIANT) and previously published onsite RCTs for HOA identified through a rigorous searching and selection strategy. The magnitude of the placebo response in the two different types of RCTs were compared using heterogeneity statistics and forest plots visualisation. Classic placebo predictors as well as a combined model, defined with data from onsite RCTs, were tested to predict the placebo response. Results: We analysed the dataset from RADIANT and fourteen previously published onsite RCTs. None of the analyses showed a significant difference between the placebo response for the internet versus onsite RCTs. The "classic" placebo predictors combined in a multivariate predictive model correlated significantly with the placebo response measured in RADIANT study. Conclusion: Despite the absence of face-to-face interactions with the study personnel, there is no evidence that either the magnitude or the predictors of the placebo response of this internet RCT differ from those of onsite RCTs. This analysis is considered as a first step towards evaluating the difference between these designs and strengthens the argument that internet RCTs remain an acceptable alternative way to assess the efficacy of an active treatment in comparison to a placebo.

Effect of institutional antimicrobial stewardship guidelines on prescription of critically important antimicrobials for dogs and cats.

BACKGROUND: Veterinary hospital antimicrobial stewardship (AMS) guidelines might help combat antimicrobial resistance (AMR). OBJECTIVES: Determine the conditions and types of infection for which antimicrobial drugs (AMDs) deemed critically important (CIA) by the World Health Organization (WHO) were prescribed and assess the effect of hospital AMS guidelines on adherence to International Society for Companion Animal Infectious Diseases published guidelines for the treatment of superficial bacterial folliculitis, respiratory tract disease and urinary tract infection in these cases. ANIMALS: Dogs and cats managed at an academic veterinary hospital from 1/21 to 6/21 and 9/21 to 6/22. METHODS: Prescriptions of cephalosporins (third or fourth generation), glycopeptides, macrolides/ketolides, polymyxins, and quinolones were identified. Data on culture and susceptibility (C/S) testing and previous AMD exposure were collected. Frequencies were compared between time periods using Fisher's exact test with Bonferroni corrections. RESULTS: In animals prescribed ≥1 WHO-CIA AMD, fluoroquinolones were the most frequently prescribed WHO-CIA class in dogs (567/1724, 32.9%) and cats (192/450, 42.7%). No animals were prescribed carbapenems, dihydrofolate reductase inhibitors/sulfonamides, or polymyxins. No cats were prescribed aminoglycosides or amphenicols. Institutional guidelines were followed in 57.8% (324/561) cases. The most frequent causes of nonadherence were failure to perform C/S testing 46.0% (109/237) and unnecessary use of a higher-tier AMD 43.0% (102/237). Bacterial C/S testing was more frequently performed after AMS guideline institution (59.7% vs. 46.8%, P = 0.0006). CONCLUSIONS AND CLINICAL IMPORTANCE: Adherence to published guidelines remained poor despite an increase in C/S testing. There were no changes in the frequencies of confirmed infections, positive cultures or AMD resistance between time periods.

Uterine fibroids and longitudinal profiles of the vaginal microbiota in a cohort presenting for transvaginal ultrasound.

Bacterial vaginosis, characterized in part by low levels of vaginal Lactobacillus species, has been associated with pro-inflammatory cytokines which could fuel uterine fibroid development. However, prior work on the associations between uterine fibroids and vaginal bacteria is sparse. Most studies have focused on assessment of individual taxa in a single sample. To address research gaps, we sought to compare short, longitudinal profiles of the vaginal microbiota in uterine fibroid cases versus controls with assessment for hormonal contraceptives (HCs), a possible confounder associated with both protection from fibroid development and increases in Lactobacillus-dominated vaginal microbiota. This is a secondary analysis of 83 reproductive-age cisgender women who presented for transvaginal ultrasound (TVUS) and self-collected mid-vaginal swabs daily for 1-2 weeks before TVUS (Range: 5-16 days, n = 697 samples). Sonography reports detailed uterine fibroid characteristics (N = 21 cases). Vaginal microbiota was assessed by 16S rRNA gene amplicon sequencing and longitudinal microbiota profiles were categorized by hierarchical clustering. We compared longitudinal profiles of the vaginal microbiota among fibroid cases and controls with exact logistic regression. Common indications for TVUS included pelvic mass (34%) and pelvic pain (39%). Fibroid cases tended to be older and report Black race. Cases less often reported HCs versus controls (32% vs. 58%). A larger proportion of cases had low-Lactobacillus longitudinal profiles (48%) than controls (34%). In unadjusted analysis, L. iners-dominated and low-Lactobacillus profiles had higher odds of fibroid case status compared to other Lactobacillus-dominated profiles, however these results were not statistically significant. No association between vaginal microbiota and fibroids was observed after adjusting for race, HC and menstruation. Results were consistent when number of fibroids were considered. There was not a statistically significant association between longitudinal profiles of vaginal microbiota and uterine fibroids after adjustment for common confounders; however, the study was limited by small sample size.

Stroke Thrombectomy and Right Atrial Clot Aspiration in 29 Year Old Woman.

We present a case report of a previously healthy 29 year old woman who developed thromboembolic events in rapid fashion after a recent orthopedic surgery. This case highlights the importance of understanding risk factors for clot formation even in those who had no prior events, the efficacy of novel aspiration techniques to remove emboli, and how rapid triaging of acute symptoms can lead to the best outcomes. She presented to the emergency department with shortness of breath and was found to have a large bilateral pulmonary embolus. She was given intravenous thrombolysis. Shortly after, she developed aphasia and right-sided weakness and was taken emergently for mechanical thrombectomy of a left middle cerebral artery occlusion. She was later found to have a patent foramen ovale and a highly mobile right atrial thrombus which was aspirated. Further evaluation revealed right lower extremity peroneal and popliteal deep venous thrombi. She was placed on anticoagulation, made a full clinical recovery, and was discharged home. Prompt recognition of symptoms, efficient in-hospital work flow, and a multidisciplinary approach led to an outstanding outcome in this young patient.

Exploring the role of sex in the association of late chronotype on cardiorespiratory fitness.

Circadian rhythms differ between young adult males and females. For example, males tend to be later chronotypes, preferring later timing of sleep and activity, than females. Likewise, there are sex differences in body composition and cardiorespiratory fitness. Few studies have investigated the association between circadian rhythms, cardiorespiratory fitness, and body composition. We sought to determine whether chronotype and circadian phase were associated with cardiorespiratory fitness, body composition, and anthropometric measures in sedentary males and females. Fifty-nine adults participated in the study. Circadian phase and chronotype were measured using dim light melatonin onset (DLMO) and the Morningness-Eveningness Questionnaire (MEQ) score. We used peak oxygen uptake (VO2peak ) results from a maximal graded exercise test to assess cardiorespiratory fitness. Body composition, BMI, and circumferences were collected as markers of adiposity. We observed a sex difference in the association between DLMO and VO2peak . For males, a later DLMO was associated with a lower VO2peak . VO2peak did not vary based on DLMO in females. Later circadian phase was also associated with increased body fat percentage, fat mass index, and abdominal circumference in males, but not females. Collectively, these results suggest that males who are later chronotypes may be at risk of obesity and low cardiorespiratory fitness.

An analogue of the Prolactin Releasing Peptide reduces obesity and promotes adult neurogenesis.

Hypothalamic Adult Neurogenesis (hAN) has been implicated in regulating energy homeostasis. Adult-generated neurons and adult Neural Stem Cells (aNSCs) in the hypothalamus control food intake and body weight. Conversely, diet-induced obesity (DIO) by high fat diets (HFD) exerts adverse influence on hAN. However, the effects of anti-obesity compounds on hAN are not known. To address this, we administered a lipidized analogue of an anti-obesity neuropeptide, Prolactin Releasing Peptide (PrRP), so-called LiPR, to mice. In the HFD context, LiPR rescued the survival of adult-born hypothalamic neurons and increased the number of aNSCs by reducing their activation. LiPR also rescued the reduction of immature hippocampal neurons and modulated calcium dynamics in iPSC-derived human neurons. In addition, some of these neurogenic effects were exerted by another anti-obesity compound, Liraglutide. These results show for the first time that anti-obesity neuropeptides influence adult neurogenesis and suggest that the neurogenic process can serve as a target of anti-obesity pharmacotherapy.

Expansion of Telestroke Coverage in Community Hospitals: Unifying Stroke Care and Reducing Transfer Rate.

OBJECTIVE: Telestroke (TS) service has been shown to improve stroke diagnosis timing and accuracy, facilitate treatment decisions, and decrease interfacility transfers. Expanding TS service to inpatient units at the community hospital provides an opportunity to follow up on stroke patients and optimize medical management. This study examines the outcome of expanding TS coverage from acute emergency room triage to incorporate inpatient consultation. METHODS: We studied the effect of expanding TS to inpatient consultation service at 19 regional hospitals affiliated with Promedica Stroke Network. We analyzed data pre- and post-TS expansion. We reviewed changes in TS utilization, admission rate, thrombolytic therapy, patient transfer rate, and diagnosis accuracy. RESULTS: Between January 2018 and June 2022, a total of 9,756 patients were evaluated in our stroke network (4,705 in pre- and 5,051 in the post-TS expansion). In the post-TS expansion period, stroke patients' admission at the spoke hospital increased from 18/month to 40/month, and for TIA from 11/month to 16/month. TS cart use increased from 12% to 35.2%. Patient transfers to hub hospital decreased by 31%. TS service expansion did not affect intravenous thrombolytic therapy rate or door-to-needle time. There was no difference in length of stay or readmission rate, and the patients at the spoke hospitals had a higher rate of home discharge 57.38% compared with 52.58% at hub hospital. INTERPRETATION: Telestroke service expansion to inpatient units helped decrease transfers and retain patients in their communities, increased stroke and TIA diagnosis accuracy, and did not compromise patients' hospitalization or outcome.

Predicting health-related quality of life change using natural language processing in thyroid cancer.

Background: Patient-reported outcomes (PRO) allow clinicians to measure health-related quality of life (HRQOL) and understand patients' treatment priorities, but obtaining PRO requires surveys which are not part of routine care. We aimed to develop a preliminary natural language processing (NLP) pipeline to extract HRQOL trajectory based on deep learning models using patient language. Materials and methods: Our data consisted of transcribed interviews of 100 patients undergoing surgical intervention for low-risk thyroid cancer, paired with HRQOL assessments completed during the same visits. Our outcome measure was HRQOL trajectory measured by the SF-12 physical and mental component scores (PCS and MCS), and average THYCA-QoL score.We constructed an NLP pipeline based on BERT, a modern deep language model that captures context semantics, to predict HRQOL trajectory as measured by the above endpoints. We compared this to baseline models using logistic regression and support vector machines trained on bag-of-words representations of transcripts obtained using Linguistic Inquiry and Word Count (LIWC). Finally, given the modest dataset size, we implemented two data augmentation methods to improve performance: first by generating synthetic samples via GPT-2, and second by changing the representation of available data via sequence-by-sequence pairing, which is a novel approach. Results: A BERT-based deep learning model, with GPT-2 synthetic sample augmentation, demonstrated an area-under-curve of 76.3% in the classification of HRQOL accuracy as measured by PCS, compared to the baseline logistic regression and bag-of-words model, which had an AUC of 59.9%. The sequence-by-sequence pairing method for augmentation had an AUC of 71.2% when used with the BERT model. Conclusions: NLP methods show promise in extracting PRO from unstructured narrative data, and in the future may aid in assessing and forecasting patients' HRQOL in response to medical treatments. Our experiments with optimization methods suggest larger amounts of novel data would further improve performance of the classification model.

Combined Digital Interventions for Pain Reduction in Patients Undergoing Knee Replacement: A Randomized Clinical Trial.

Importance: Digital technology represents an opportunity to improve outcomes following total knee replacement (TKR). Digitally delivered interventions have been shown to be similar to face-to-face interventions and to increase participation levels in people with osteoarthritis. Objective: To assess the effect of a digital technology package in reducing pain compared with usual care following TKR. Design, Setting, and Participants: This randomized clinical trial recruited 102 adults after they received TKR in 3 rehabilitation hospitals in Sydney, Australia, between June 2020 and July 2021. Interventions: All participants underwent usual care. In addition to usual care, 51 participants received a digital technology package consisting of an exercise app, fitness tracker, and online health coaching. In the usual care group, 51 participants received a fitness tracker but with all notifications turned off and goals for step count, sleep, and active hours removed. Participants were followed up for 12 months (June 2021 to July 2022). Main Outcome and Measures: The primary outcome was mean knee pain during the past week assessed using a numerical rating scale (range, 0-10, with 10 indicating worst possible pain) at 3 months. In unadjusted analyses, considered primary and based on multiple imputations, independent t tests were used to compare means between groups. Secondary outcomes, including measures of function, activity participation, and quality of life, were analyzed using a generalized estimating equation model that accounted for repeated measurements. Results: Of 102 participants (mean [SD] age, 67.9 [7.2] years; 68 [67%] female; and 92 [90%] White) randomly assigned to intervention or usual care groups, 47 (92%) in each group completed the 3-month follow up. At 3 months, participants in the intervention group demonstrated small but not clinically meaningful improvements in pain compared with the usual care group in the unadjusted intention-to-treat analysis (mean difference, -0.84; 95% CI, -1.59 to -0.10; P = .03). Secondary outcomes indicated a statistically significant reduction in pain intensity, (mean difference, -0.94; 95% CI, -1.82 to -0.06), pain disability (mean difference, -5.42; 95% CI, -10.00 to -0.83), and sedentary behavior (mean difference, -9.76; 95% CI, -19.17 to -0.34) favoring the intervention from baseline to 3, 6, and 12 months. Conclusions and Relevance: In this randomized clinical trial, a combined digital technology program provided small but not clinically meaningful improvements in pain at 3 months and other longer-term favorable outcomes following TKR compared with usual care. Future studies should tailor digital interventions based on participants' abilities and preferences to ensure that the intervention is appropriate and fosters long-term self-management.

Baseline knee osteoarthritis radiographic severity as a predictor of symptom response to diet and exercise program: A secondary analysis.

OBJECTIVE: To investigate whether baseline joint space narrowing (JSN) predicted disease remission, knee pain, and physical function changes in persons with knee osteoarthritis (OA). METHODS: This study is a secondary analysis of a two-armed randomized controlled trial. Participants were aged ≥50 years (n = 171) with a body mass index ≥28 kg/m2 and radiographic medial tibiofemoral OA. Participants in the intervention group received diet and exercise programs and special treatment (cognitive behavioral therapy, knee brace, and muscle strengthening exercises) according to the disease remission. Remission of pain and remission of patient global assessment of disease activity and/or functional impairment were used to define the disease remission. The control group were provided with an education pamphlet. The primary outcome was disease remission at 32 weeks, and the secondary outcomes were the changes in knee pain and physical function at 20 and 32 weeks. Baseline JSN was scored from 0 to 3, and the association between baseline JSN and outcomes was assessed using multiple regression. RESULTS: There was no association of baseline JSN with disease remission at 32 weeks when the disease remission has been achieved. The baseline JSN grade 3 was associated with changes in knee pain at 20 weeks (p < .05). There was no association between baseline JSN and physical function. CONCLUSION: Baseline JSN severity predicted changes in knee pain but not the disease remission or changes in physical functions. Identification of baseline radiographic severity may be helpful in identifying differences in response to diet and exercise programs in knee OA.

Sexual activity satisfaction in symptomatic hip osteoarthritis patients: A cross-sectional, national web-based study.

AIM: Despite high-interest rates in sex in people with hip osteoarthritis (OA), clinicians tend not to address sexual issues, especially in older adults. The objective of this study is to evaluate sexual activity and factors associated with sexual activity satisfaction in people with symptomatic hip OA. METHODS: A cross-sectional study was conducted among 252 participants with symptomatic hip OA in Australia. Quality of sex life was assessed using the online composite of sexual activities and positions questionnaires. A Poisson model with robust variance was used to calculate the prevalence ratio (PR). Factors that showed a univariate association with sexual satisfaction were then included in a multivariable model. PR with corresponding 95% confidence intervals (CI) are reported. RESULTS: Among the 282 participants registered on the study website, 252 met the inclusion criteria, and 60.3% (152/252) completed the sexual activity questionnaires. Hip OA interfered with sexual activity in 70.0% of the participants. High confidence in completing sexual activity (PR: 0.53, 95% CI: 0.36 to 0.77) was associated with an increased prevalence ratio of sexual satisfaction. High anxiety, depression or stress during sexual activity (PR: 1.33, 95% CI: 1.10 to 1.60) was associated with an increased prevalence ratio of sexual dissatisfaction after adjusting for hip pain level and perceived partner's orgasm. CONCLUSION: Although a large proportion of people with hip OA remain sexually active, a substantial proportion of persons are dissatisfied with their sexual activity. Hip OA interfered with sexual activity in most participants. Psychological factors were found to be associated with sexual activity satisfaction.

An Observational Study on HIV and Syphilis Rates and Associated Risk Factors among Elderly Men in Wuxi, China.

BACKGROUND: Acquired Immune Deficiency Syndrome (AIDS) remains a nationwide health problem in China; there were a reported 1,045,000 people living with Human immunodeficiency virus (HIV)/AIDS by the end of October 2020, and the proportion of individuals aged 50 years and older living with HIV has also increased from 8% to 24% over the past two decades. METHODS: A cross-sectional study and an 1:2 matched case-control study were conducted from July to August 2016, in Wuxi city, eastern China. A total of 1,000 men aged 50 years and older completed a face-to-face interview regarding their AIDS-related knowledge and attitudes, as well as risk behaviors. RESULTS: Prevalence was 0.1% for HIV and 2% for syphilis. The awareness rate of AIDS-related knowledge among elderly men was 48.9% (range 40.7%-63.9%). The 1꞉2 matched case-control study indicated that only the AIDS-related attitudes were different between the two groups (χ2=8.726, P=0.013), the conditional logistic regression analysis indicated that scores of AIDS health knowledge were the only significant prognostic factor for the infection (HR=0.754 (0.569- 0.999), P=0.049). CONCLUSION: It was crucial to prevent HIV/AIDS and syphilis infections by improving the awareness of AIDS-related knowledge and changing related attitudes among the elderly. Further research aimed at identifying how these factors impact their sexual decision-making can shed valuable insight into further prevention program in this population.

Comparison of Computer-Assisted Self-Interview Versus Clinician Interview for Self-Reported Vulvovaginal Symptoms.

ABSTRACT: This secondary analysis (N = 43) compared computer-assisted self-interview (CASI) to clinician interview for self-report of 8 vulvovaginal symptoms. Concordance was moderate between interview modes (range, 70-86%) with itching and odor having highest agreement. Although prior reports suggest more responses on CASI, we found CASI did not significantly increase self-report of symptoms over clinician interview.

Pain, function, and radiographic disease in trapeziometacarpal osteoarthritis.

INTRODUCTION: Trapeziometacarpal joint osteoarthritis (OA) produces significant functional impairment due to pain and loss of strength in both power and precision grips, but few studies have related radiographic scores to functional and pain-based measures. PURPOSE: To investigate the association between markers of radiographic disease and outcomes for symptomatic and functional disease. STUDY DESIGN: This study in an exploratory analysis of baseline data from the first 100 participants in a clinical trial evaluating the efficacy of combined conservative therapies for base of thumb OA (COMBO). METHODS: Functional Index for Hand Osteoarthritis (FIHOA) scores and Visual Analogue Scale (VAS) scores for pain were recorded for the index hand. Bilateral isometric grip and tip-pinch strength measurements were taken, as well as posteroanterior and Eaton stress-view hand radiographs. Generalized estimating equations (GEEs), univariate, and multivariate analyses were used according to whether the data were bilateral or unilateral. RESULTS: A total of 79 females and 21 males were included, with a median Kellgren-Lawrence (KL) grade of 3 in the index hand. Higher KL and Eaton grades were associated with lower grip strength in the GEE analysis (B-coefficients of -1.25 and -1.16, and P-values of .002 and .010, respectively). Higher KL grade was also associated with poorer function and higher pain levels in the multivariable analysis (B-coefficients of 1.029 and 3.681, and P-values of .021 and .047, respectively). Lower radial subluxation ratios were associated with lower grip strength in the GEE analysis, and higher pain scores in the multivariable analysis (B-coefficients of 2.06 and -42.1, and P-values of .006 and .031, respectively). Greater pain scores were also associated with poorer function (B-coefficient 0.082, P-value .001). CONCLUSION: More advanced radiographic trapeziometacarpal OA severity is associated with lower grip strength and poorer self-reported functional outcomes. Lower subluxation ratios were associated with higher pain scores and lower grip strength.

Impact of Satisfactory/Unsatisfactory Grading on Student Motivation to Learn, Academic Performance, and Well-Being.

Satisfactory/unsatisfactory (S/U) grading is often proposed to ameliorate stress by reducing the competitive nature of letter grading. Though explored considerably in human medical programs, minimal literature focuses on the veterinary school setting. The purpose of this study was to evaluate the impact of S/U grading on veterinary students' motivation to learn, academic performance, and well-being. Cornell University's COVID-19 pandemic response provided a unique opportunity to compare S/U and letter grading on the same population of students during a single pre-clinical foundation course, with the first half being graded S/U (spring semester 2020), returning to letter grades in the second half (fall semester 2020). Students were retroactively surveyed on the effect of S/U vs. letter grading on their overall educational experience and well-being, with 67.8% class participation. The majority of respondents (71.3%) stated that S/U grading had a positive impact on their overall learning experience. More than half (53.8%) perceived that they learned the same amount of information and had the same level of motivation (58.8%), even though most (61.3%) stated that they spent less time preparing for S/U assessments than letter grade assessments. Positive impact factor effects for S/U grading included decreased stress, more time for self-care, improved learning, and increased learning enjoyment. S/U grading did not negatively impact academic performance. In conclusion, this study demonstrates that, in our particular study population and setting, S/U grading conferred well-being and learning experience advantages to students without any reduction in motivation for learning or academic performance.

Patients Follow Different Financial Hardship Trajectories in the Year after Injury.

OBJECTIVE: To determine if distinct financial trajectories exist and if they are associated with quality-of-life outcomes. SUMMARY OF BACKGROUND DATA: Financial hardship after injury measurably impacts Health-Related Quality of Life outcomes. Financial hardship, encompassing material losses, financial worry, and poor coping mechanisms, is associated with lower quality of life and increased psychological distress. However, recovery is dynamic and financial hardship may change over time. METHODS: This is a secondary analysis of a cohort of 500 moderate-to-severe nonneurologic injured patients in which financial hardship and Health-related Quality of Life outcomes were measured at 1, 2, 4, and 12 months after injury using survey instruments (Short Form-36). Enrollment occurred at an urban, academic, Level 1 trauma center in Memphis, Tennessee during January 2009 to December 2011 and follow-up completed by December 2012. RESULTS: Four hundred seventy-four patients had sufficient data for Group- Based Trajectory Analysis. Four distinct financial hardship trajectories were identified: Financially Secure patients (8.6%) had consistently low hardship over time; Financially Devastated patients had a high degree of hardship immediately after injury and never recovered (51.6%); Financially Frail patients had increasing hardship over time (33.6%); and Financially Resilient patients started with a high degree of hardship but recovered by year end (6.2%). At 12-months, all trajectories had poor Short Form-36 physical component scores and the Financial Frail and Financially Devastated trajectories had poor mental health scores compared to US population norms. CONCLUSIONS AND RELEVANCE: The Financially Resilient trajectory demonstrates financial hardship after injury can be overcome. Further research into understanding why and how this occurs is needed.

Determinants of quality of life and hand function among people with hand osteoarthritis.

OBJECTIVE: The objectives of this study are to ascertain the determinants of quality of life (QoL) and hand function among persons with hand osteoarthritis (OA) and to assess the influence of hand function on QoL among persons with OA. METHODOLOGY: Two hundred and four participants in a clinical trial completed the baseline assessment. Demographic, socioeconomic, QoL (AqoL-4D), hand function (Functional Index for Hand Osteoarthritis, FIHOA), pain assessment, radiographic and clinical characteristics of participants were measured using standard methods. Univariate and multivariate analyses were performed to evaluate potential associations. RESULTS: We studied 204 participants (76% female, age 65.63 ± 8.13 years, body mass index 28.7 ± 6.5 kg/m2 ) with hand OA. The mean pain score of the participants on a visual analog scale was 57.8 (SD ±13.6). There was a significant, negative moderate correlation between hand function and QoL scores except for the sense domain score. Global assessment, household income and serious illness were associated with QoL (P < .001) and explained 18% of the variance of the QoL. Pain scale, Patient Global Assessment, Mental Health Score, grip strength and cyst index were associated with hand function score and explained 26% of the variance of hand function. CONCLUSION: The results indicate increasing impairment in hand function decreases the QoL of persons with hand OA. Some determinants were significantly associated with hand function and QoL. Determinants related to hand functions may be modifiable. In future, appropriate intervention strategies should be implemented, and further studies should be conducted to identify the effectiveness of those interventions.

Predictors of Adherence to a Step Count Intervention Following Total Knee Replacement: An Exploratory Cohort Study.

OBJECTIVE: To explore the person-level predictors of adherence to a step count intervention following total knee replacement (TKR). DESIGN: Prospective cohort study, nested within the PATHway trial. METHODS: Participants who had recently undergone TKR were recruited from 3 rehabilitation hospitals in Sydney, Australia, for the main trial. Only data from participants who were randomized to the TKR intervention group were analyzed. Participants in the intervention group (n = 51) received a wearable tracker to monitor the number of steps taken per day. Step count adherence was objectively measured at 3 months as the number of steps completed divided by the number prescribed and multiplied by 100 to express adherence as a percentage. Participants were classified into 4 groups: withdrawal, low adherence (0%-79%), adherent (80%-100%), and >100% adherent. Ordinal logistic regression was used to identify which factors predicted adherence to the prescribed step count. RESULTS: Of the 51 participants enrolled, nine (18% of 51) withdrew from the study before 3 months. Half of participants were classified as >100% adherent (n = 24%, 47%). Ten were classified as low adherence (20%), and 8 participants were classified as adherent (16%). In the univariable model, lower age (OR 0.90; 95% CI 0.83-0.97), higher patient activation (OR 1.03; 95% CI 1.00-1.06), and higher technology self-efficacy (OR 1.03; 95% CI 1.00-1.06) were associated with higher adherence. After adjusting for age in the multivariable model, patient activation and technology self-efficacy were not significant. CONCLUSION: Younger age, higher patient activation, and higher technology self-efficacy were associated with higher adherence to a step count intervention following TKR in the univariable model. Patient activation and technology self-efficacy were not associated with higher adherence following adjustment for age. J Orthop Sports Phys Ther 2022;52(9):620-629.

Correlations between objective and self-reported step count adherence following total knee replacement: A longitudinal repeated-measures cohort study.

OBJECTIVE: To determine how physically active individuals are following total knee replacement (TKR) and how accurately they self-report their step count adherence compared to objective measure following TKR. METHODS: Observational cohort study, nested within the PATHway randomised-clinical trial. Participants (n = 102) who had recently undergone TKR were recruited for the main trial. Only participant data from the intervention group were used for this study (n = 51). Participants in the intervention group received an activity tracker to monitor their physical activity and fortnightly health-coaching sessions for 3 months. Adherence was objectively measured as percentage of steps completed divided by the amount prescribed by the health coach. Participants were asked to self-report their adherence on a 1-10 numerical rating scale during health coaching sessions. RESULTS: Data from 44 participants were available, resulting in a total of 224 paired measurements. Participant step count increased over the first 8 weeks of follow-up, and plateaued from 8 weeks onwards at approximately 7500 steps/day. About two-thirds (65.8%) of participants accurately self-reported their step count adherence up until 12 weeks, the remaining one-third (34.2%) underestimated their adherence. Paired t-tests demonstrated statistically significant differences between the paired measurements from weeks 2 to 10. DISCUSSION: Participants were generally active and completed the step goal most occasions. Two-thirds accurately self-reported their step goal adherence. Self-reported measures should be combined with an objective measure of adherence for greater accuracy. A further understanding of how people engage with activity trackers can be used to promote behaviour change in physiotherapy-led interventions.
