Objectives: To examine how change in benzodiazepine (BZD) use is linked to changes in depressive symptoms intensity, worry intensity, and sleep quality over 16 months., Method: Data come from a larger randomised controlled trial (RCT) named the 'Programme d'Aide du Succès au SEvrage (PASSE-60+)' study (NCT02281175). Seventy-three participants age 60 years and older took part in a 4-month discontinuation programme and were assessed four times over 16 months. Change in BZD use was defined as the difference in reported mg/day between two assessments. Control variables were RCT discontinuation group; BZD use at T1; and either depressive symptoms, worry intensity, or sleep quality at T1. Hierarchical multiple regressions were used to analyse data., Results: In the short term, right after the discontinuation programme, sleep quality worsened with lower BZD use. This link was no longer significant at the 3- and 12-month follow-up. In the long term, depressive symptoms lowered with lower BZD use. No change was found in worry intensity in relation to BZD use at all measurement times., Conclusion: Discontinuation may improve depressive symptoms. Our study also questions the long-term effectiveness of BZD use, since long-term discontinuation was not linked with change in worry intensity and sleep quality.

Background: The use of COVID-19 vaccines has been prioritised to protect the most vulnerable-notably, older people. Because of fluctuations in vaccine availability, strategies such as delayed second dose and heterologous prime-boost have been used. However, the effectiveness of these strategies in frail, older people are unknown. We aimed to assess the antigenicity of mRNA-based COVID-19 vaccines in frail, older people in a real-world setting, with a rationed interval dosing of 16 weeks between the prime and boost doses., Methods: This prospective observational cohort study was done across 12 long-term care facilities of the Montréal Centre-Sud - Integrated University Health and Social Services Centre in Montréal, Québec, Canada. Under a rationing strategy mandated by the provincial government, adults aged 65 years and older residing in long-term care facilities in Québec, Canada, with or without previously documented SARS-CoV-2 infection, were administered homologous or heterologous mRNA vaccines, with an extended 16-week interval between doses. All older residents in participating long-term care facilities who received two vaccine doses were eligible for inclusion in this study. Participants were enrolled from Dec 31, 2020, to Feb 16, 2021, and data were collected up to June 9, 2021. Clinical data and blood samples were serially collected from participants at the following timepoints: at baseline, before the first dose; 4 weeks after the first dose; 6-10 weeks after the first dose; 16 weeks after the first dose, up to 2 days before administration of the second dose; and 4 weeks after the second dose. Sera were tested for SARS-CoV-2-specific IgG antibodies (to the trimeric spike protein, the receptor-binding domain [RBD] of the spike protein, and the nucleocapsid protein) by automated chemiluminescent ELISA. Two cohorts were used in this study: a discovery cohort, for which blood samples were collected before administration of the first vaccine dose and longitudinally thereafter; and a confirmatory cohort, for which blood samples were only collected from 4 weeks after the prime dose. Analyses were done in the discovery cohort, with validation in the confirmatory cohort, when applicable., Findings: The total study sample consisted of 185 participants. 65 participants received two doses of mRNA-1273 (Spikevax; Moderna), 36 received two doses of BNT162b2 (Comirnaty; Pfizer-BioNTech), and 84 received mRNA-1273 followed by BNT162b2. In the discovery cohort, after a significant increase in anti-RBD and anti-spike IgG concentrations 4 weeks after the prime dose (from 4·86 log binding antibody units [BAU]/mL to 8·53 log BAU/mL for anti-RBD IgG and from 5·21 log BAU/mL to 8·05 log BAU/mL for anti-spike IgG), there was a significant decline in anti-RBD and anti-spike IgG concentrations until the boost dose (7·10 log BAU/mL for anti-RBD IgG and 7·60 log BAU/mL for anti-spike IgG), followed by an increase 4 weeks later for both vaccines (9·58 log BAU/mL for anti-RBD IgG and 9·23 log BAU/mL for anti-spike IgG). SARS-CoV-2-naive individuals showed lower antibody responses than previously infected individuals at all timepoints tested up to 16 weeks after the prime dose, but achieved similar antibody responses to previously infected participants by 4 weeks after the second dose. Individuals primed with the BNT162b2 vaccine showed a larger decrease in mean anti-RBD and anti-spike IgG concentrations with a 16-week interval between doses (from 8·12 log BAU/mL to 4·25 log BAU/mL for anti-RBD IgG responses and from 8·18 log BAU/mL to 6·66 log BAU/mL for anti-spike IgG responses) than did those who received the mRNA-1273 vaccine (two doses of mRNA-1273: from 8·06 log BAU/mL to 7·49 log BAU/mL for anti-RBD IgG responses and from 6·82 log BAU/mL to 7·56 log BAU/mL for anti-spike IgG responses; mRNA-1273 followed by BNT162b2: from 8·83 log BAU/mL to 7·95 log BAU/mL for anti-RBD IgG responses and from 8·50 log BAU/mL to 7·97 log BAU/mL for anti-spike IgG responses). No differences in antibody responses 4 weeks after the second dose were noted between the two vaccines, in either homologous or heterologous combinations., Interpretation: Interim results of this ongoing longitudinal study show that among frail, older people, previous SARS-CoV-2 infection and the type of mRNA vaccine influenced antibody responses when used with a 16-week interval between doses. In these cohorts of frail, older individuals with a similar age and comorbidity distribution, we found that serological responses were similar and clinically equivalent between the discovery and confirmatory cohorts. Homologous and heterologous use of mRNA vaccines was not associated with significant differences in antibody responses 4 weeks following the second dose, supporting their interchangeability., Funding: Public Health Agency of Canada, Vaccine Surveillance Reference Group; and the COVID-19 Immunity Task Force., Translation: For the French translation of the abstract see Supplementary Materials section., Competing Interests: DCV is funded by the Fonds de la recherche en santé du Québec clinician-scientist scholar Junior 2 Program; has received clinical trial support from Cidara Therapeutics, CSL Behring, and Janssen Pharmaceuticals; has served on advisory boards for CSL Behring, Novartis Canada, and UCB Biosciences; has received speaker honoraria from CSL Behring and Merck Canada; and has a patent application pending (Electronic Filing System ID: 40101099) and a report of invention to McGill University (Track code: D2021-0043), both unrelated to this work.

Objective: Benzodiazepines (BZD) are often prescribed to address sleep difficulties but many BZD users report a poor quality of sleep. Although social support was found to be associated with quality of sleep in a recent meta-analysis, this relationship was never studied in older BZD users. This study thus aims to examine how social support is associated with quality of sleep in older BZD users. Method: Seventy-two older adults (age 60-85) using BZD were recruited. Data was collected during the pre-test of the ''PASSE-60+; Support program for a successful withdrawal, NCT02281175'' study. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI), while social support was evaluated with the Social Support Questionnaire (SSQ-6). Results: When examining the various dimensions of self-reported sleep quality as a whole, we found no significant association with social support, while controlling for daily BZD dose, anxiety and depression. However, we found a significant association between self-reported diurnal dysfunctions (e.g., daytime sleepiness) and satisfaction with social support. Conclusion: Although the results of our study should be replicated with larger samples, they might indicate that social support is not a significant factor influencing sleep quality in older chronic BZD users. Our results could differ from those found in other populations because of the changes in sleep quality associated with long term BZD use. Longitudinal studies should analyse the relationship between diurnal dysfunctions and satisfaction with social support, to examine if social support could help older adults alleviate their diurnal dysfunctions and eventually facilitate BZD tapering.

An elderly woman admitted in our geriatric inpatient unit suffered from disturbing outbursts of crying and, less frequently, episodes of laughing. The patient was diagnosed with pseudobulbar affect related to a mixed neurodegenerative disorder. This condition is often underdiagnosed and undertreated, despite being relatively frequent in patients with neurodegenerative disorders. This case report describes the treatment of pseudobulbar affect in this patient. The only available treatment in Canada for this condition, antidepressants, was not effective for our patient. Dextromethorphan/quinidine is a good accepted alternative, but the combination is not marketed in Canada. To manage this problem, we used compounded quinidine capsules and dextromethorphan cough syrup. The crying of our patient improved significantly and rapidly after the initiation of this treatment. This case will help professionals to review their central role in treating this complex and disabling condition., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

Background: Long-term benzodiazepine (BZD) use among seniors is mostly inappropriate and associated with adverse health outcomes. To prevent these consequences, withdrawal is crucial, yet knowledge is limited about what predicts BZD discontinuation. Until now, most studies have focused on sociodemographic and BZD intake factors as predictors while neglecting psychological factors. This research addresses this issue by studying how the intensity of depressive symptoms, social support satisfaction, self-perceived competence in the ability to withdraw, and overall quality of sleep predict discontinuation in long-term older consumers., Method: Seventy-three participants aged 60 years and older were enrolled in this study. There were four time measures: before discontinuation (T1), after (T2), 3 months after (T3), and 12 months after (T4). Data were collected in the "Programme d'Aide du Succès au SEvrage" (PASSE-60+) study., Results: Social support satisfaction predicted discontinuation at T2 and T4. Self-perceived competence in the ability to withdraw and depressive symptoms predicted discontinuation at T4. This later prediction was counterintuitive; higher depressive symptoms at T1 were linked with higher discontinuation success. BZD intake factors (length of use and dose) were good predictors for short term discontinuation. Psychological factors were moderate predictors for short term and good predictors for long term discontinuation., Conclusion: Psychological factors are good predictors of discontinuation and are better predictors than BZD intake factors of long-term discontinuation. Discontinuation programs should focus on social support and self-perceived competence to improve their efficacy. Further studies are needed to acquire a more complete picture of the psychological predictors of discontinuation success. ClinicalTrials.gov Identifier: NCT02281175., (Copyright © 2019 Elsevier Ltd.

Objective: A relationship between generalized anxiety disorder (GAD) and fear of falling (FOF) has long been proposed but never specifically studied. This study aimed at analyzing the relationship between FOF and GAD or anxiety symptoms, while controlling for major depressive episodes (MDE), depressive symptoms, fall risk, and sociodemographic variables., Methods: Twenty-five older adults participated in this pilot study. Assessments included the following: Anxiety Disorder Interview Schedule, Geriatric Anxiety Inventory, Geriatric Depression Scale, Falls-Efficacy Scale-International. A multidisciplinary team evaluated fall risk., Results: FOF was significantly correlated with GAD, MDE, anxiety and depressive symptoms, and fall risk, but not with sociodemographic variables. Multiple regression analyses indicated that GAD and anxiety symptoms were significantly and independently associated with FOF., Conclusion: Although the results of this pilot study should be replicated with larger samples, they suggest that FOF is associated with GAD and anxiety symptoms even when considering physical factors that increase the risk of falling., Clinical Implications: Treatment of FOF in patients with GAD may present a particular challenge because of the central role of intolerance of uncertainty, which may prevent patients from regaining confidence despite the reduction of fall risk. Clinicians should screen for GAD and anxiety symptoms in patients with FOF to improve detection and treatment.

Background: Since the onset of the global COVID-19 pandemic in early 2020, numerous studies have been conducted worldwide to understand our immune response to the virus and to vaccination. This study investigates the humoral response elicited by SARS-CoV-2 infection and by vaccination in the poorly studied population of food and retail workers. These occupations were classified as essential by the Public Health Agency of Canada, potentially placing this population at greater risk of infection. Such a risk requires access to reliable and adaptable serological assays that can be rapidly deployed to guide public health strategies. Here we investigate the benefits and limitations of applying adaptable, decentralized tests for population-level immune surveillance in response to a pandemic, even before centralized testing is available. Methods and findings: The 1.5-year study period spans from early 2021, when vaccination became available in this region, to mid-2022, following the emergence of the first Omicron variants. The cohort of 304 food and retail workers was recruited in the Québec City area. Participants attended five evenly spaced visits, providing blood samples as well as information on SARS-CoV-2 symptoms or risk factors, prior antigen or PCR test results and vaccination status, as well as work-related risk factors and protective measures. Parallel COVID-19 serological assays were performed using both a standardized chemiluminescent ELISA assay at the centralized platform operated in partnership with the Public Health Agency of Canada, and a semi-automated in-house colorimetric ELISA assay developed at our decentralized site. The YES/NO determination of SARS-CoV-2 vaccine seroconversion and/or infection events using the SARS-CoV-2 ancestral spike protein and nucleocapsid protein validated coherence of the centralized and decentralized assays. The flexibility of the decentralized assays allowed broadening the study to determine cross-reactivity of IgG directed against the spike protein of the SARS-CoV-2 Delta and Omicron VOCs, and IgM directed against the ancestral spike and nucleocapsid proteins. The nature of the data obtained in the decentralized assays allowed treatment with a recently developed mathematical transformation to obtain normal distribution, enabling ANOVA-Welsh statistical analysis. Although no significant differences were observed in humoral response as related to BMI, age, level of education, or chronic illnesses in this cohort of workers, statistically higher levels of vaccine-induced antibodies were observed for restaurant workers and hardware store workers in the early stages of the study, compared to workers in bars and grocery stores and in non-smokers versus smokers. Conclusions: This work highlights the importance of developing adaptable, decentralized tests for population-level immune surveillance in response to a pandemic, even before centralized testing is available. To our knowledge, no other study has reported such an extensive longitudinal investigation during key periods of the COVID-19 pandemic in a cohort of food and retail workers to analyze two types of immunoglobulin, three epitopes and antigens to three VOC. This study will inform strategies and measures to be implemented in the event of a future pandemic. [ABSTRACT FROM AUTHOR]

Understanding variables that influence antibody responses to COVID-19 vaccination within a population can provide valuable information on future vaccination strategies. In this population-based study, we examined the antibody responses to COVID-19 vaccination in Manitoba using residual serum specimens collected between January 2021 and March 2022 (n = 20,365). Samples were tested for spike and nucleocapsid IgG against SARS-CoV-2 using clinically validated assays. We assessed the impacts of multiple factors on post-vaccination antibody titres including type of vaccine, age, sex, geographic location, number of doses received, and timing of vaccination. Our investigation demonstrated that vaccination with one dose of Moderna mRNA-1273 elicited higher anti-spike IgG titres overall compared to Pfizer BNT162b2 vaccination, while one dose of Pfizer BNT162b2 followed by a second dose of Moderna mRNA-1273 exhibited higher titres than two doses of Pfizer BNT162b2 or Moderna mRNA-1273, irrespective of age. Age and time post-vaccination had considerable effects on antibody responses, with older age groups exhibiting lower anti-spike IgG titres than younger ages, and titres of those vaccinated with Pfizer BNT162b2 waning faster than those vaccinated with Moderna mRNA-1273 or a combination of Pfizer BNT162b2 and Moderna mRNA-1273. Antibody titres did not appear to be affected by sex or geographic location. Our results identify how factors such as age and type of vaccine can influence antibody responses to vaccination, and how antibody titres wane over time. This information highlights the importance of tailoring vaccine regimens to specific populations, especially those at increased risk of severe COVID-19 and can be used to inform future vaccination strategies, scheduling of booster doses, and public health measures.

COVID-19 breakthrough infection (BTI) can occur despite vaccination. Using a multi-centre, prospective, observational Canadian cohort of people with HIV (PWH) receiving ≥2 COVID-19 vaccines, we compared the SARS-CoV-2 spike (S) and receptor-binding domain (RBD)-specific IgG levels 3 and 6 months post second dose, as well as 1 month post third dose, in PWH with and without BTI. BTI was defined as positivity based on self-report measures (data up to last study visit) or IgG data (up to 1 month post dose 3). The self-report measures were based on their symptoms and either a positive PCR or rapid antigen test. The analysis was restricted to persons without previous COVID-19 infection. Persons without BTI remained COVID-19-naïve until ≥3 months following the third dose. Of 289 participants, 92 developed BTI (31.5 infections per 100 person-years). The median days between last vaccination and BTI was 128 (IQR 67, 176), with the most cases occurring between the third and fourth dose (n = 59), corresponding to the Omicron wave. In analyses adjusted for age, sex, race, multimorbidity, hypertension, chronic kidney disease, diabetes and obesity, a lower IgG S/RBD (log10 BAU/mL) at 1 month post dose 3 was significantly associated with BTI, suggesting that a lower IgG level at this time point may predict BTI in this cohort of PWH.

This study evaluates the incidence and characteristics of adverse events (AEs) following the second COVID-19 booster dose, leveraging Taiwan's distinctive approach of extending booster vaccinations to all citizens, unlike the targeted high-risk group strategies in other countries. Utilizing data from Taipei Veterans General Hospital's Vaccine Adverse Event Reporting System (VAERS) from 27 October 2022 to 19 January 2023, this research examines AEs in 441 out of 1711 booster recipients, considering factors like age, vaccine brands, and booster combinations. The findings revealed incidence rates (IRs) of 25.6% (95% CI: 21.1–30.8) after the first booster and 24.9% (95% CI: 20.5–30.0) after the second, mostly non-serious, with those having AEs post-first booster being five times more likely to report them again (incidence rate ratio, 5.02, p < 0.001). Significantly, switching from the mRNA1273 vaccine to another brand reduced AE risk by 18%. This study underscores that AEs are more repetitive than cumulative with additional booster doses, advocating for personalized vaccination strategies based on individual medical histories and previous vaccine reactions. These insights are valuable for healthcare providers in discussing potential AEs with patients, thereby improving vaccine compliance and public trust, and for policymakers in planning future booster vaccination strategies.

Background: Immune responses to vaccination vary widely between individuals. The aim of this study was to identify health-related variables potentially underlying the antibody responses to SARS-CoV-2 vaccination in older persons. We recruited participants in the long-running Doetinchem Cohort Study (DCS) who underwent vaccination as part of the national COVID-19 program, and measured antibody concentrations to SARS-CoV-2 Spike protein (S1) and Nucleoprotein (N) at baseline (T0), and a month after both the first vaccination (T1), and the second vaccination (T2). Associations between the antibody concentrations and demographic variables, including age, sex, socio-economic status (SES), comorbidities (cardiovascular diseases and immune mediated diseases), various health parameters (cardiometabolic markers, inflammation markers, kidney- and lung function) and a composite measure of frailty ('frailty index', ranging from 0 to 1) were tested using multivariate models. Results: We included 1457 persons aged 50 to 92 years old. Of these persons 1257 were infection naïve after their primary vaccination series. The majority (N = 954) of these individuals were vaccinated with two doses of BNT162b2 (Pfizer) and their data were used for further analysis. A higher frailty index was associated with lower anti-S1 antibody responses at T1 and T2 for both men (RT1 = -0.095, PT1 = 0.05; RT2 = -0.11, PT2 = 0.02) and women (RT1 = -0.24, PT1 < 0.01; RT2 = -0.15, PT2 < 0.01). After correcting for age and sex the frailty index was also associated with the relative increase in anti-S1 IgG concentrations between the two vaccinations (β = 1.6, P < 0.01). Within the construct of frailty, history of a cardiac catheterization, diabetes, gastrointestinal disease, a cognitive speed in the lowest decile of the population distribution, and impaired lung function were associated with lower antibody responses after both vaccinations. Conclusions: Components of frailty play a key role in the primary vaccination response to the BNT162b2 vaccine within an ageing population. Older persons with various comorbidities have a lowered immune response after their first vaccination, and while frail and sick older persons see a stronger increase after their second vaccination compared to healthy people, they still have a lower antibody response after their second vaccination.

Background: The COVID-19 pandemic has inflicted tremendous pressure on people, including older adults. Frail older adults are more susceptible to the adverse consequences of the pandemic. Although many studies have investigated the susceptibility and poor medical outcomes of COVID-19 in frail people, a few studies have explored the psychosocial effects of the pandemic on this group of vulnerable people. This study overviews the psychosocial consequences of the pandemic and necessary public interventions for frail older adults. Materials and Methods: An integrative review method was utilized to gather, analyze, and structure the study data. PubMed, Web of Science, and Scopus databases were searched to extract the published English papers based on a designed strategy. The keywords and used Boolean operators in their titles or abstracts were (["COVID-19" OR "CORONA" OR "SARS-CoV-2"] AND ["frail" OR "frailty"]). A total of 50 articles (47 quantitative, 2 qualitative, and 1 mixed method) were selected for the final analysis. Results: Anxiety and depression were reported as the most significant psychological consequences in the related studies. The results also indicated the social relations of older frail people and their access to health services noticeably reduced during the pandemic. On the other hand, physical exercise programs, telemedicine, and reading activities were the most preventive measures to mitigate the impacts of public restrictions during the pandemic. Conclusion: The results of this review can assist policymakers in reflecting appropriate psychosocial support for frail seniors during the pandemic. As most studies on the psychosocial aspects of the COVID-19 pandemic among frail older adults are quantitative and have been performed in developed countries, it is suggested to conduct further qualitative studies. These studies should explore frail older adults' experiences and perceptions and their challenges during the pandemic, particularly in developing countries. [ABSTRACT FROM AUTHOR]

Long-term care facilities (LTCFs) were severely affected by COVID-19, in particular in Northern Italy. We aimed to assess antibody responses among residents and healthcare workers (HCWs) of 13 LTCFs through serum samples collected at three time points: prior to, two weeks, and 9 months after receiving Pfizer/BNT162b2 SARS-CoV-2 mRNA vaccine (respectively t0, t1, and t2). IgG antibodies targeted towards the S1 domain of the spike protein were measured, and results were expressed in binding antibody units (BAU/mL). Friedman's average rank test was performed to compare antibody titres between the three time points. Two logistic regression models were built to identify independent predictors of (1) developing and (2) maintaining a significant antibody response to vaccination, using a previously identified threshold. In total, 534 subjects were enrolled (371 HCWs and 163 residents). The antibody titres at t1 were the highest; at t2, the IgG titres significantly decreased, remaining however 10 times higher compared to titres at t0. Previous infection was the only significant predictor of developing and maintaining a response over threshold in both models. Results of this study provided further insights on the humoral response elicited by vaccination, and on host factors determining variations in its magnitude and kinetics. [ABSTRACT FROM AUTHOR]

Objectives: Antibody testing against severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has been instrumental in detecting previous exposures and analyzing vaccine‐elicited immune responses. Here, we describe a scalable solution to detect and quantify SARS‐CoV‐2 antibodies, discriminate between natural infection‐ and vaccination‐induced responses, and assess antibody‐mediated inhibition of the spike‐angiotensin converting enzyme 2 (ACE2) interaction. Methods: We developed methods and reagents to detect SARS‐CoV‐2 antibodies by enzyme‐linked immunosorbent assay (ELISA). The main assays focus on the parallel detection of immunoglobulin (Ig)Gs against the spike trimer, its receptor binding domain (RBD) and nucleocapsid (N). We automated a surrogate neutralisation (sn)ELISA that measures inhibition of ACE2‐spike or ‐RBD interactions by antibodies. The assays were calibrated to a World Health Organization reference standard. Results: Our single‐point IgG‐based ELISAs accurately distinguished non‐infected and infected individuals. For seroprevalence assessment (in a non‐vaccinated cohort), classifying a sample as positive if antibodies were detected for ≥ 2 of the 3 antigens provided the highest specificity. In vaccinated cohorts, increases in anti‐spike and ‐RBD (but not ‐N) antibodies are observed. We present detailed protocols for serum/plasma or dried blood spots analysis performed manually and on automated platforms. The snELISA can be performed automatically at single points, increasing its scalability. Conclusions: Measuring antibodies to three viral antigens and identify neutralising antibodies capable of disrupting spike‐ACE2 interactions in high‐throughput enables large‐scale analyses of humoral immune responses to SARS‐CoV‐2 infection and vaccination. The reagents are available to enable scaling up of standardised serological assays, permitting inter‐laboratory data comparison and aggregation. [ABSTRACT FROM AUTHOR]

Background: The factors that lead to the fear of falling among older people after total knee arthroplasty (TKA) are poorly understood. The present study aims to examine the fear of falling among such patients and to determine the factors that are associated with that fear. Methods: A total of 285 patients aged ≥65 with knee osteoarthritis who underwent TKA at an orthopaedic hospital between November 2019 and May 2020 completed surveys about their own first mobilisation after TKA. They were asked to indicate whether they were afraid of falling by asking a single question, and what their pain level was on a visual analogue scale. They also completed the General Anxiety Disorder scale, the Geriatric Depression Scale–Short Form and the Social Support Rating Scale. Multivariate logistic regression was used to identify risk factors for fear of falling during the first mobilisation after TKA. This study was reported in compliance with the STROBE checklist for cross‐sectional studies (see Supplementary File S1). Results: Just over half (56.5%) of participants reported being afraid of falling. Multivariate logistic regression identified three independent risk factors that explained a total of 31% of the variance in the fear of falling: female sex (odds ratio (OR) = 4.21, 95% confidence interval (CI) = 2.35–7.55), higher body mass index (OR =3.93, 95% CI =1.53–10.10) and higher anxiety (OR = 1.56, 95% CI = 1.37–1.78). Conclusions: Many older patients fear falling when they begin to move after TKA, particularly women and those with higher body mass index or anxiety. These subgroups may merit special attention from healthcare professionals to mitigate their fears and optimise recovery after TKA. [ABSTRACT FROM AUTHOR]

Purpose Of Review: Anxiety disorders are the most prevalent mental disorders. Although prevalence estimates are lower in males than females, the disability associated with anxiety disorders has been increasing in males. This review focuses on recent research studying sex differences in anxiety disorders and associated symptoms in older adults.Recent Findings: Females are close to three times more likely than males to report most anxiety disorders. Heterogeneity exists in sex-specific lifetime and past-year estimates. Age-appropriate instruments such as the CIDI65+ show higher estimates than previous research. The profiles of females and males with anxiety with respect to depressive and somatization symptoms are different. Age-appropriate standardized mental disorder instruments have been developed and may be useful to overcome the challenges of observed heterogeneity in anxiety disorders and allow for future cross-country comparisons and a better description of the epidemiology and biopsychosocial factors associated with different types of anxiety disorders in older adults.
