Abstract
BACKGROUND Despite their frequent concurrent use, little is known about the concomitant use of calcium channel blockers (CCBs) and selective serotonin reuptake inhibitors (SSRIs) on fracture risk. We compared risk of fractures in patients concomitantly treated with CCBs and SSRIs versus CCB-only users. We compared risk of fractures among concomitant CCB-SSRI users initiating cytochrome P450 3A4 (CYP3A4)-inhibiting SSRIs versus non-CYP3A4 inhibiting SSRIs. METHODS This retrospective cohort study used IBM MarketScan commercial claims and Medicare Supplemental database (2007-2019). We included adults diagnosed with hypertension and depression, newly initiating SSRIs while being treated with CCBs (ie, concomitant CCB-SSRI users) and those who did not (ie, CCB-only users). Primary outcome was the first occurrence of any fracture. We used stabilized inverse probability of treatment weighting (sIPTW) based on propensity scores to balance baseline risk between groups. Cox proportional hazard regression modeling was used to compare fracture risk. RESULTS We identified 191 352 concomitant CCB-SSRI and 956 760 CCB-only users (mean age = 56 years, 50.1% males). After sIPTW, compared with CCB-only users, CCBs-SSRIs users had a higher risk of fractures (hazard ratio [HR]: 1.43, 95% confidence interval [CI]: 1.22-1.66). No difference in the risk of fractures between concomitant users of CCB-CYP3A4-inhibiting SSRIs and those of CCB-non-CYP3A4 inhibiting SSRIs (HR: 1.10, 95% CI: 0.87-1.40) was observed. CONCLUSION AND RELEVANCE Short-term concomitant CCB-SSRI use was associated with increased fracture risk. Concomitant CCBs and CYP3A4-inhibiting SSRIs compared with CCBs and non-CYP3A4 inhibiting SSRIs use was not associated with increased risk.

Abstract
Background Orthostatic intolerance (OI) is the inability to tolerate orthostatic stress during any postural change. The etiology of OI varies, and methods to obtain a specific diagnosis and plan appropriate treatment are important. The tools available within the Chinese context to swiftly identify orthostatic intolerance syndrome (OIS) are currently limited. Methods Patients with OI symptoms were included in this study and categorized into two groups based on the results of the supine-to-stand test. Those with abnormal test results were assigned to the OIS group, while those with normal test results were placed in the non-OIS group. We evaluated the internal consistency and predictive value of the Chinese Orthostatic Discriminant and Severity Scale (ODSS) by comparing patients' scores with their physiological measurements collected during orthostatic stress tests and the results of other available questionnaires, including the orthostatic Symptom Questionnaire and Orthostatic Grading Scale (OGS). Results Patients with OIS scored significantly higher on all three questionnaires and showed significant differences in autonomic responses during orthostatic stress tests compared with non-OIS patients. Receiver operating characteristic curve analysis showed that the orthostatic score from the ODSS had moderate predictive value for the supine test (area under the curve [AUC] = 0.754). Further subgroup analysis revealed that the orthostatic score from the ODSS had uniquely high specificity and sensitivity for identifying patients with orthostatic hypotension with abnormal cerebral blood flow (OH-U, AUC = 0.919). Conclusions We conclude that the Chinese version of the ODSS has sufficient reliability and validity to distinguish patients with OIS and could possibly be used as a diagnostic tool for OH-U patients. Thus, the Chinese ODSS offers a beneficial screening tool for quickly assessing whether patients have OIS that requires further clinical assessment.

Public Health 2024; 233:54-59. [PMID: 38848620 DOI: 10.1016/j.puhe.2024.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 03/24/2024] [Accepted: 04/05/2024] [Indexed: 06/09/2024]
Abstract
OBJECTIVE The main objective was to determine the prevalence of falls and associated factors in older adults living in Qatar. STUDY DESIGN Cross-sectional study. METHODS This is a cross-sectional study of older adults aged ≥60 years with at least one encounter with primary health care corporation (PHCC) in Qatar during the period 2017-2022. Data on documented falls, demographic variables, and medical comorbidities were extracted from all PHCCs in Qatar. Descriptive and inferential statistics were used to address the aim of the study. RESULTS A total of 68,194 older adults had at least one encounter with PHCC. The median age was 65.0 years, 58.9% were males, and 32.6% were Qatari nationality. A higher percentage of falls was found in individuals with hypertension (80%), diabetes (74.2%), and dyslipidemia (48.9%), which were also the most prevalent comorbidities. The prevalence of falls was 6.7% (95% CI 6.6-6.9). Compared to individuals aged 60-69 years, individuals aged 70-79, 80-89, and 90-99 had increased odds of falls by 1.6 (95% CI 1.5, 1.8), 2.5 (95% CI 2.2, 2.8), and 2.6 (95% CI 2.0, 3.3), respectively. Females and individuals of Qatari nationality had increased odds of fall by 1.5 (95% CI 1.4, 1.6) and 1.2 (95% CI 1.1, 1.3), respectively. Orthostatic hypotension, syncope, Parkinson's disease, and hip arthritis showed the strongest associations with falls. CONCLUSIONS Given the growing population of older adults in the Middle East and North African region, falls is a public health concern. The risk factors identified in this study suggest the need for proactive healthcare strategies tailored to the unique needs of older adult populations.

Abstract
Background An integrated haemodynamic response during standing may serve as an integrative marker of neuro-cardiovascular function. Individual components of both heart rate (HR) and blood pressure (BP) responses to active stand (AS) have been linked with cardiovascular disease (CVD) and mortality. We assessed longitudinal associations between entire HR/BP response curves during AS, incident CVD and mortality over 12 years. Methods Beat-to-beat measurements of dynamic HR/BP responses to AS were conducted in 4,336 individuals (61.5±8.2 years; 53.7% female). Functional Principal Components Analysis was applied to HR/BP response curves and their association with CVD and mortality assessed. We hypothesised that integrating BP/HR information from the entire haemodynamic response curve may uncover novel associations with both CVD and mortality. Results Higher systolic BP (SBP) before AS and blunted recovery of SBP during AS was associated with all-cause mortality over 12-years (Hazard Ratio [HR]: 1.14; 1.04, 1.26; p=0.007). Higher baseline/peak HR and lower HR from 30 seconds post stand onwards were associated with lower mortality due to circulatory causes (HR: 0.78; 0.64, 0.95; p = 0.013). Higher HR throughout AS was associated with mortality from other causes (HR: 1.48; 1.22, 1.80; p<0.001). Findings persisted on robust covariate adjustment. Conclusions We observed distinct relationships between HR/BP responses to AS and 12-year incident CVD and mortality. Integrating the entire haemodynamic response may reveal more nuanced relationships between HR/BP responses to AS, CVD and mortality - serving as an integrative marker of neuro-cardiovascular health in midlife and beyond.

Abstract
BACKGROUND Falls are a significant public health problem and constitute a major cause of injuries and mortality. Risk factors for falls are multifactorial and include medication use. AIM To develop and investigate the content validity of the Medication-Related fall (MRF) screening and scoring tool. METHOD The MRF tool was developed from clinical practice guidelines addressing medication-related problems, and additional medications identified by specialist pharmacists across a region of the United Kingdom (Northern Ireland). Medication classes were categorised according to their 'potential to cause falls' as: high-risk (three points), moderate-risk (two points) or low-risk (one point). The overall medication-related falls risk for the patient was determined by summing the scores for all medications. The MRF was validated using Delphi consensus methodology, whereby three iterative rounds of surveys were conducted using SurveyMonkey®. Twenty-two experts from 10 countries determined their agreement with the falls risk associated with each medication on a 5-point Likert scale. Only medications with at least 75% of respondents agreeing or strongly agreeing were retained in the next round. RESULTS Consensus was reached for 19 medications/medication classes to be included in the final version of the MRF tool; ten were classified as high-risk, eight as moderate-risk and one as low-risk. CONCLUSION The MRF tool is simple and has the potential to be integrated into medicines optimisation to reduce falls risk and negative fall-related outcomes. The score from the MRF tool can be used as a clinical parameter to assess the need for medication review and clinical interventions.

The effect of a change in antihypertensive treatment on orthostatic hypotension in older adults: A systematic review and meta-analysis. Exp Gerontol 2024; 193:112461. [PMID: 38772447 DOI: 10.1016/j.exger.2024.112461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 05/07/2024] [Accepted: 05/15/2024] [Indexed: 05/23/2024]
Abstract
BACKGROUND Orthostatic hypotension (OH) is common in older adults with hypertension. Antihypertensive treatment (AHT) prevents cardio- and cerebrovascular events. However, physicians are concerned to cause OH, making them hesitant to initiate or augment AHT in older adults with hypertension. METHODS We systematically researched electronic databases for trials with older participants (≥65 years) with hypertension and OH assessment after initiating, discontinuing, or augmenting AHT. Study quality was assessed using the ROBINS-I tool. Meta-analyses on OH prevalence and postural blood pressure (BP) drop were performed. RESULTS Twenty-five studies (26,695 participants) met inclusion criteria, of which fifteen could be included in the meta-analyses. OH prevalence decreased after AHT initiation or augmentation (risk ratio 0.39 (95 % CI = 0.21-0.72; I2 = 47 %; p < 0.01), n = 6 studies), but also after AHT discontinuation (risk ratio 0.39 (95 % CI = 0.28-0.55; I2 = 0 %; p < 0.01), n = 2 studies). Postural BP drop did not change after initiation or augmentation of AHT (mean difference 1.07 (95 % CI = -0.49-2.64; I2 = 92 %; p = 0.18), n = 11 studies). The main reason for ten studies not to be included in the meta-analyses was absence of baseline OH data. Most of these studies reported OH incidences between 0 and 2 %. Studies were heterogeneous in OH assessment methods (postural change, timing of BP measurements, and OH definition). Risk of bias was moderate to serious in twenty studies. CONCLUSION Results suggest that AHT initiation or augmentation decreases OH prevalence, implying that the risk of inducing OH may be overestimated in current AHT decision-making in older adults. However, the overall low level of evidence and the finding that AHT discontinuation reduces OH prevalence limit firm conclusions at present and highlight an important research gap. Future AHT trials in older adults should measure OH in a standardized protocol, adhering to consensus guidelines to overcome these limitations.

Abstract
Orthostatic hypotension (OH) is prevalent in older adults and can cause falls and hospitalization. Diagnostic intermittent blood pressure (BP) measurements are only a proxy for cerebral perfusion and do not reflect daily-life BP fluctuations. Near-infrared spectroscopy (NIRS)-measured cerebral oxygenation potentially overcomes these drawbacks. This study aimed to determine feasibility, face validity, and reliability of NIRS in the home environment. Ten participants with OH (2 female, mean age 77, SD 3.7) and 11 without OH (5 female, mean age 78, SD 6.7) wore a NIRS sensor at home on two different days for 10-11 h per day. Preceded by a laboratory-situated test, cerebral oxygenation was measured during three standardized supine-stand tests per day and during unsupervised daily life activities. Data availability, quality, and user experience were assessed (feasibility), as well as differences in posture-related oxygenation responses between participants with and without OH and between symptomatic (dizziness, light-headedness, blurred vision) and asymptomatic postural changes (face validity). Reliability was assessed through repetitive supine-stand tests. Up to 80% of the standardized home-based supine-stand tests could be analyzed. Oxygenation recovery values were lower for participants with OH (p = 0 .03-0.15); in those with OH, oxygenation showed a deeper maximum drop for symptomatic than asymptomatic postural changes (p = 0.04). Intra-class correlation coefficients varied from 0.07 to 0.40, with no consistent differences over measurements. This proof-of-concept study shows feasibility and face validity of at-home oxygenation monitoring using NIRS, confirming its potential value for diagnosis and monitoring in OH and OH-related symptoms. Further data are needed for conclusions about reliability.

Abstract
PURPOSE OF REVIEW To summarise the evidence regarding which patients might benefit from deprescribing antihypertensive medications. RECENT FINDINGS Older patients with frailty, multi-morbidity and subsequent polypharmacy are at higher risk of adverse events from antihypertensive treatment, and therefore may benefit from antihypertensive deprescribing. It is possible to examine an individual's risk of these adverse events, and use this to identify those people where the benefits of treatment may be outweighed by the harms. While such patients might be considered for deprescribing, the long-term effects of this treatment strategy remain unclear. Evidence now exists to support identification of those who are at risk of adverse events from antihypertensive treatment. These patients could be targeted for deprescribing interventions, although the long-term benefits and harms of this approach are unclear. PERSPECTIVES Randomised controlled trials are still needed to examine the long-term effects of deprescribing in high-risk patients with frailty and multi-morbidity.

Abstract
OBJECTIVES Falls pose a significant challenge in residential aged care facilities (RACFs). Existing falls prediction tools perform poorly and fail to capture evolving risk factors. We aimed to develop and internally validate dynamic fall risk prediction models and create point-based scoring systems for residents with and without dementia. MATERIALS AND METHODS A longitudinal cohort study using electronic data from 27 RACFs in Sydney, Australia. The study included 5492 permanent residents, with a 70%-30% split for training and validation. The outcome measure was the incidence of falls. We tracked residents for 60 months, using monthly landmarks with 1-month prediction windows. We employed landmarking dynamic prediction for model development, a time-dependent area under receiver operating characteristics curve (AUROCC) for model evaluations, and a regression coefficient approach to create point-based scoring systems. RESULTS The model identified 15 independent predictors of falls in dementia and 12 in nondementia cohorts. Falls history was the key predictor of subsequent falls in both dementia (HR 4.75, 95% CI, 4.45-5.06) and nondementia cohorts (HR 4.20, 95% CI, 3.87-4.57). The AUROCC across landmarks ranged from 0.67 to 0.87 for dementia and from 0.66 to 0.86 for nondementia cohorts but generally remained between 0.75 and 0.85 in both cohorts. The total point risk score ranged from -2 to 57 for dementia and 0 to 52 for nondementia cohorts. DISCUSSION Our novel risk prediction models and scoring systems provide timely person-centered information for continuous monitoring of fall risk in RACFs. CONCLUSION Embedding these tools within electronic health records could facilitate the implementation of targeted proactive interventions to prevent falls.

[PMID: 37689483 DOI: 10.1111/1742-6723.14315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 08/10/2023] [Accepted: 08/26/2023] [Indexed: 09/11/2023]
Abstract
OBJECTIVE Orthostatic hypotension (OH) is associated with increased morbidity and there is limited research on the prevalence in the Australian ED population. The aim was to determine the prevalence of OH in an Australian ED population. Secondary outcomes included any associations of OH with symptoms, presenting complaints, patient demographics, or hospital admission, and the timing of OH findings. METHODS Patients presenting to a regional Australasian ED underwent orthostatic measurements at 1, 3 and 5 min of standing following 5 min of supine bed rest. OH was defined as a drop in systolic and/or diastolic blood pressure by ≥20 and ≥10 mmHg, respectively. RESULTS Of the 312 patients who were enrolled in the study, 69 (22.1%, 95% confidence interval 17.7-27.2%) had OH and 76.8% of cases were detected after 3 min of standing. There was evidence of difference in the prevalence of OH with age (P < 0.001). Similarly, there was evidence of a difference in supine systolic and diastolic blood pressure measurements (P = 0.012 and P < 0.001, respectively) between orthostatic and normotensive subjects. No association was found with OH and hospital admission, presenting complaints or comorbid medical illnesses. CONCLUSIONS In this single Australian ED population, there was a high prevalence of OH (22.1%) with most cases detected within 3 min of standing. A higher-powered study across multiple sites would better substantiate these findings.

Abstract
OBJECTIVE Scarce evidence is available to elucidate the association between the abnormal microstructure of white matter (WM) and cognitive performance in patients with orthostatic hypotension (OH). This study investigated the microstructural integrity of WM in patients with mild OH (MOH) and severe OH (SOH) and evaluated the association of abnormal WM microstructure with the broad cognitive domains and cognition-related plasma biomarkers. METHODS Our study included 72 non-OH (NOH), 17 MOH, and 11 SOH participants. Across the groups, the WM integrity was analyzed by neurite orientation dispersion and density imaging (NODDI), and differences in WM microstructure were evaluated by nonparametric tests and post hoc models. The correlations between WM microstructure and broad cognitive domains and cognition-related plasma biomarkers were assessed by Spearman's correlation analysis. RESULTS The abnormal WM microstructure was localized to the WM fiber bundles in MOH patients but distributed widely in SOH cohorts (p < 0.05). Further analysis showed that the neurite density index of the left cingulate gyrus was negatively associated with amyloid β-40, glial fibrillary acidic protein, neurofilament light chain, phospho-tau181 (p < 0.05) but positively with global cognitive function (MOCA, MMSE, AER-III), memory, attention, language, language fluency, visuospatial function and amyloid β-40 / amyloid β-42 (p < 0.05). Additionally, other abnormal WM microstructures of OH were associated with broad cognitive domains and cognition-related plasma biomarkers to varying degrees. CONCLUSION The findings evidence that abnormal WM microstructures may present themselves as early as in the MOH phase and that these structural abnormalities are associated with cognitive functions and cognition-related plasma biomarkers.

Abstract
Orthostatic hypotension is defined as a drop in systolic blood pressure of at least 20mmHg or a drop in diastolic blood pressure of at least 10mmHg within 3minutes of standing. It is a common disorder, especially in high-risk populations such as elderly subjects and patients with neurological diseases, and is associated with markedly increased morbidity and mortality. Its management can be challenging, particularly in cases where supine hypertension is associated with severe orthostatic hypotension. Education of the patient, non-pharmacological measures, and drug adaptation are the cornerstones of treatment. Pharmacological treatment should be individualized according to the severity, underlying cause, 24-hour blood pressure profile, and associated coexisting conditions. First-line therapies are midodrine and fludrocortisone, which may need to be combined for optimal care of severe cases.

The physiologic complexity of beat-to-beat blood pressure is associated with age-related alterations in blood pressure regulation. Aging Cell 2024; 23:e13943. [PMID: 37615223 PMCID: PMC10776119 DOI: 10.1111/acel.13943] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 07/12/2023] [Accepted: 07/14/2023] [Indexed: 08/25/2023] Open
Abstract
The fluctuations in resting-state beat-to-beat blood pressure (BP) are physiologically complex, and the degree of such BP complexity is believed to reflect the multiscale regulation of this critical physiologic process. Hypertension (HTN), one common age-related condition, is associated with altered BP regulation and diminished system responsiveness to perturbations such as orthostatic change. We thus aimed to characterize the impact of HTN on resting-state BP complexity, as well as the relationship between BP complexity and both adaptive capacity and underlying vascular characteristics. We recruited 392 participants (age: 60-91 years), including 144 that were normotensive and 248 with HTN (140 controlled- and 108 uncontrolled-HTN). Participants completed a 10-min continuous finger BP recording during supine rest, then underwent measures of lying-to-standing BP change, arterial stiffness (i.e., brachial-ankle pulse wave velocity), and endothelial function (i.e., flow-mediated vasodilation). The complexity of supine beat-to-beat systolic (SBP) and diastolic (DBP) BP was quantified using multiscale entropy. Thirty participants with HTN (16 controlled-HTN and 14 uncontrolled-HTN) exhibited orthostatic hypotension. SBP and DBP complexity was greatest in normotensive participants, lower in those with controlled-HTN, and lowest in those in uncontrolled-HTN (p < 0.0005). Lower SBP and DBP complexity correlated with greater lying-to-standing decrease in SBP and DBP level (β = -0.33 to -0.19, p < 0.01), greater arterial stiffness (β = -0.35 to -0.18, p < 0.01), and worse endothelial function (β = 0.17-0.22, p < 0.01), both across all participants and within the control- and uncontrolled-HTN groups. These results suggest that in older adults, BP complexity may capture the integrity of multiple interacting physiologic mechanisms that regulate BP and are important to cardiovascular health.

Abstract
Beta-blocker usage is inconsistently associated with increased fall risk in the literature. However, due to age-related changes and interindividual heterogeneity in pharmacokinetics and dynamics, it is difficult to predict which older adults are more at risk for falls. Therefore, we wanted to explore whether elevated plasma concentrations of selective and nonselective beta-blockers are associated with an increased risk of falls in older beta-blocker users. To answer our research question, we analyzed samples of selective (metoprolol, n = 316) and nonselective beta-blockers (sotalol, timolol, propranolol, and carvedilol, n = 179) users from the B-PROOF cohort. The associations between the beta-blocker concentration and time to first fall were assessed using Cox proportional hazard models. Change of concentration over time in relation to fall risk was assessed with logistic regression models. Models were adjusted for potential confounders. Our results showed that above the median concentration of metoprolol was associated with an increased fall risk (HR 1.55 [1.11-2.16], p = .01). No association was found for nonselective beta-blocker concentrations. Also, changes in concentration over time were not associated with increased fall risk. To conclude, metoprolol plasma concentrations were associated with an increased risk of falls in metoprolol users while no associations were found for nonselective beta-blockers users. This might be caused by a decreased β1-selectivity in high plasma concentrations. In the future, beta-blocker concentrations could potentially help clinicians estimate fall risk in older beta-blockers users and personalize treatment.

Abstract
Orthostatic hypotension (OH) is common in older people. We examined the influence of self-reported occupational-related physical activity (PA) and leisure-time physical exercise (PE) on orthostatic response in a sample of older people over a 2 year period. Supine and orthostatic systolic blood pressure (sBP), diastolic blood pressure (dBP), and mean blood pressure (mBP) were assessed in response to Active Stand (AS) test in 205 older subjects (> 60 years old) at baseline and 2-year follow-up. OH was found in 24 subjects (11.71%) at baseline and 20 subjects (9.76%) after 2 years, with a significant degree of variability in the occurrence of OH after 2 years. Twenty-two subjects who had OH at baseline were free of it after 2 years, two subjects had persistent OH at baseline and after 2 years. After 2 years, adults with occupational PA showed no significant decrease of blood pressure in response to AS test, while lack of undertaking an occupation-related PA was significantly related with a greater decrease in sBP and mBP in response to AS testing in the 1st min. Occupation-related PA and leisure-time-related PE were related to an increase in the response of BP on AS in change between baseline and after 2 years. High between-subjects variance in OH over 2 years was noted. Occupations that involved continuous physical activity and leisure-time physical exercise in middle age were both protective for BP decline on orthostatic stress test within 2 years.

Differential Associations Between Two Markers of Probable Sarcopenia and Continuous Orthostatic Hemodynamics in The Irish Longitudinal Study on Ageing.

Abstract
BACKGROUND Sarcopenia and orthostatic hypotension are growing age-related health burdens associated with adverse outcomes, including falls. Despite a possible pathophysiological link, the association between the 2 disorders is not well elucidated. We sought to investigate this relationship in The Irish Longitudinal Study on Ageing (TILDA). METHODS Data from 2 858 participants at wave 3 of TILDA were analyzed. Probable sarcopenia was defined as per the European Working Group on Sarcopenia in Older People revised definition cutoffs (hand grip strength [HGS] <27 kg in men, <16 kg in women, and/or 5-chair stand test [5CST] time >15 seconds). Participants underwent an active stand orthostatic test with continuous blood pressure (BP) monitoring. Multilevel mixed-effects models, controlling for possible confounders, were used to assess the effect of probable sarcopenia by HGS and 5CST criteria on the change in BP after standing. RESULTS HGS- and 5CST-defined probable sarcopenia were independently associated with an attenuated BP recovery at 10-20 seconds poststand (systolic BP: β -0.54, p < .001; β -0.25, p < .001). On average, those meeting HGS probable sarcopenia criteria had a significantly lower BP at 20, 30, and 40 seconds (differences in systolic BP: -5.01 mmHg, -3.68 mmHg, -2.32 mmHg, p < .05 for all). Those meeting 5CST probable sarcopenia criteria had a significant difference in systolic BP at 20 seconds (-1.94 mmHg, p = .002) but not at 30 or 40 seconds. CONCLUSION Probable sarcopenia had a significant association with delayed orthostatic BP recovery, with HGS-defined probable sarcopenia having a stronger association than 5CST-defined probable sarcopenia. Results support a modest but significant pathophysiological link between probable sarcopenia and orthostatic hypotension.

Abstract
Orthostatic hypotension (OH) is highly prevalent in older adults and associated with dizziness, falls, lower physical and cognitive function, cardiovascular disease, and mortality. OH is currently diagnosed in a clinical setting with single-time point cuff measurements. Continuous blood pressure (BP) devices can measure OH dynamics but cannot be used for daily life monitoring. Near-infrared spectroscopy (NIRS) has potential diagnostic value in measuring cerebral oxygenation continuously over a longer time period, but this needs further validation. This study aimed to compare NIRS-measured (cerebral) oxygenation with continuous BP and transcranial Doppler-measured cerebral blood velocity (CBv) during postural changes. This cross-sectional study included 41 participants between 20 and 88 years old. BP, CBv, and cerebral (long channels) and superficial (short channels) oxygenated hemoglobin (O2Hb) were measured continuously during various postural changes. Pearson correlations between BP, CBv, and O2Hb were calculated over curves and specific characteristics (maximum drop amplitude and recovery). BP and O2Hb only showed good curve-based correlations (0.58-0.75) in the initial 30 s after standing up. Early (30-40 s) and 1-min BP recovery associated significantly with O2Hb, but no consistent associations were found for maximum drop amplitude and late (60-175 s) recovery values. Associations between CBv and O2Hb were poor, but stronger for long-channel than short-channel measurements. BP associated well with NIRS-measured O2Hb in the first 30 s after postural change. Stronger associations for CBv with long-channel O2Hb suggest that long-channel NIRS specifically reflects cerebral blood flow during postural transitions, necessary to better understand the consequences of OH such as intolerance symptoms.

Abstract
OBJECTIVES To evaluate the association of falls and in-hospital mortality with the presence of orthostatic hypotension and type 2 diabetes mellitus (T2D). The study also aims to identify whether the orthostatic hypotension assessed at 1 min or at 3 min can predict falls and mortality, as a secondary objective to identify the predictors of fall during hospitalization. METHODS We performed a prospective study with patients admitted to a university hospital. The risk of falls was assessed using the Morse questionnaire and the presence of falls was verified by the patient's medical records during hospitalization. The orthostatic hypotension was determined by measuring blood pressure at three times, considering as orthostatic hypotension the reduction of at least 20 mmHg in SBP or 10 mmHg in DBP. In-hospital mortality was consulted in the medical records. RESULTS Patients with orthostatic hypotension were slower on Timed Up and Go test (TUG) (12.26 ± 3.16 vs. 16.08 ± 5.96 s, P = 20 s) and presence of orthostatic hypotension. After adjustments, patients with T2D and orthostatic hypotension had a 2.7 times greater risk of in-hospital falls and 1.54 times greater odds of in-hospital mortality when compared with patients without T2D and orthostatic hypotension. CONCLUSION In this sample, sedentary patients and those with lower TUG had a higher risk of falls. The prevalence of falls was higher in patients with T2D. The association of T2D with orthostatic hypotension significantly increased both the risk of falls and the risk of in-hospital mortality.

Are higher antidepressant plasma concentrations associated with fall risk in older antidepressant users? Eur Geriatr Med 2023; 14:89-97.

Abstract
PURPOSE Antidepressants are well-established fall-risk increasing drugs (FRIDs) and therefore falls should be considered an important adverse drug event (ADE) of antidepressants. However, not all antidepressant users experience fall incidents and factors associated with increased fall risk among antidepressant users are incompletely understood. Our objective was to explore whether antidepressant plasma concentrations are associated with falls in older antidepressant users. METHODS For this study, we included antidepressant users of the multicenter B-PROOF study. Fall incidents were recorded prospectively using fall calendars. Antidepressant plasma concentrations were analyzed by Liquid chromatography-mass spectrometry (LC-MS) at baseline and at 2 years follow-up. The associations between the observed antidepressant concentration and fall risk were assessed using Cox proportional hazard and logistic regression models and adjusted for potential confounders. RESULTS In total 93 selective serotonin reuptake inhibitor (SSRI) and 41 antidepressant (TCA) users were identified. There was a significant association between baseline TCA plasma concentration and fall risk within users (HR 2.50, 95% CI 1.07-5.87, crude model). In the adjusted model, there were no significant associations between concentrations of SSRIs and fall risk. CONCLUSION There might be an association between plasma concentrations of TCAs and the risk of falling in older users. However, these results needs to be interpreted with caution considering the small sample size and accompanying limitation of confinement to crude analyses. Therefore, these novel findings need to replicated in a larger cohort, preferably including adjustment for potential confounders and more frequent measures of plasma concentrations is needed.

Abstract
INTRODUCTION Autonomic dysfunction is prevalent in ischemic stroke patients and associated with a worse clinical outcome. We aimed to evaluate autonomic dysfunction over time and the tolerability of the head-up tilt table test in an acute stroke setting to optimize patient care. PATIENTS AND METHOD In a prospective observational cohort study, patients were consecutively recruited from an acute stroke unit. The patients underwent heart rate and blood pressure analysis during the Valsalva maneuver, deep breathing, active standing, and head-up tilt table test if active standing was tolerated. In addition, heart rate variability and catecholamines were measured. All tests were performed within seven days after index ischemic stroke and repeated at six months follow-up. RESULTS The cohort was comprised of 91 acute stroke patients, mean (SD) age 66 (11) years, median (IQR) initial National Institute of Health Stroke Scale 2 (1-4) and modified Ranking Scale 2 (1-3). The head-up tilt table test revealed 7 patients (10%) with orthostatic hypotension. The examination was terminated before it was completed in 15%, but none developed neurological symptoms. In the acute state the prevalence of autonomic dysfunction varied between 10-100% depending on the test. No changes were found in presence and severity of autonomic dysfunction over time. CONCLUSION In this cohort study of patients with mild stroke, autonomic dysfunction was highly prevalent and persisted six months after index stroke. Head-up tilt table test may be used in patients who tolerate active standing. Autonomic dysfunction should be recognized and handled in the early phase after stroke.

Abstract
OBJECTIVES Although the vagus nerve (VN) is easily observed by ultrasonography, few studies have evaluated the cross-sectional area (CSA) of the VN in healthy older individuals from East Asia. In this study, we aimed to report reference values for the CSA of the VN in community-dwelling elderly Japanese individuals and to identify any associated medical history and/or lifestyle factors. METHODS The present study included 336 participants aged ≥ 70 years from a prospective cohort study conducted in Yahaba, Japan from October 2021 to February 2022. The CSA of the VN was measured bilaterally at the level of the thyroid gland by ultrasonography. Simple linear regression analysis and generalized estimating equation were conducted to identify the associations between clinical and background factors and the CSA of the VN. RESULTS In our cohort, the median CSA of the VN was 1.3 mm2 (interquartile range [IQR] 1.1-1.6) on the right side and 1.2 mm2 (IQR 1.0-1.4) on the left side. Generalized estimating equation showed that history of head injury (β = 0.19, p < .01), current smoking habit (β = -0.09, p = .03), and BMI (β = 0.02, p < .01) were independently associated with the CSA of the VN. CONCLUSION We have reported reference VN CSA values for community-dwelling elderly Japanese individuals. In addition, we showed that the CSA of the VN was positively associated with a history of head injury and BMI and inversely associated with current smoking habit.

Abstract
BACKGROUND Orthostatic hypotension (OH) in Parkinson's disease (PD) is frequent and associated with impairments in quality of life and reduced activities of daily living. Abdominal binders (AB) and compression stockings (CS) have been shown to be effective non-pharmacological treatment options. OBJECTIVE Here, we investigate the effect of AB versus CS on physical activity using a digital mobility outcome (sit to stand [STS] frequency) collected in the usual environment as a primary endpoint. METHODS We enrolled 16 PD patients with at least moderate symptomatic OH. In a randomized, single-blinded, controlled, crossover design, participants were assessed without OH treatment over 1 week (baseline), then were given AB or CS for 1 week and subsequently switched to the other treatment arm. The primary outcome was the number of real-life STS movements per hour as assessed with a lower back sensor. Secondary outcomes included real-life STS duration, mean/systolic/diastolic blood pressure drop (BPD), orthostatic hypotension questionnaire (OHQ), PD quality of life (PDQ-39), autonomic symptoms (SCOPA-AUT), non-motor symptoms (NMSS), MDS-UPDRS, and activities of daily living (ADL/iADL). RESULTS Real-life STS frequency on CS was 4.4±4.1 per hour compared with 3.6±2.2 on AB and 3.6±1.8 without treatment (p = 1.0). Concerning the secondary outcomes, NMSS showed significant improvement with CS and AB. OHQ and SCOPA-AUT improved significantly with AB but not CS, and mean BPD drop worsened with CS but not AB. Mean STS duration, PDQ-39, MDS-UPDRS, ADL, and iADL did not significantly change. CONCLUSION Both AB and CS therapies do not lead to a significant change of physical activity in PD patients with at least moderate symptomatic OH. Secondary results speak for an effect of both therapies concerning non-motor symptoms, with superiority of AB therapy over CS therapy.

Abstract
Background Chimeric antigen receptor T-cell (CART) therapy is a form of cellular immunotherapy used to treat hematologic malignancies. Major adverse cardiovascular events have been seen in CART patients who have high grade CRS, higher baseline creatinine, and troponin elevation. However, the incidence and factors associated with orthostatic hypotension after CART therapy have not previously been reported in the literature. Methods We looked at patients who underwent CD-19 directed CART therapy at UPMC Shadyside hospital from April 1st 2018 to December 1st 2020. Patients were classified as having orthostatic hypotension if they had recorded orthostatic vital signs that were positive or provider notes indicated that vitals had been taken and were positive in the time period from discharge to 3 months post-CART. Data was analyzed with univariate and multivariate analysis using logistic regression. Results 79% of patients had orthostatic hypotension after discharge from their CART hospitalization and 64% of those patients were symptomatic. Older age, lower BMI, lower ambulatory diastolic blood pressure and grade 2 CRS were associated with orthostatic hypotension in the univariate analysis. Older age and lower ambulatory systolic blood pressure were associated with orthostatic hypotension in the multivariate analysis. Symptomatic orthostatic hypotension was associated with a history of hypertension in both the univariate and multivariate analysis. Patients with symptoms also had a higher pre-CART ejection fraction but this association was not seen in the regression model. Conclusion There is a high incidence of orthostatic hypotension after CART therapy even after discharge. Therefore, orthostatic vitals signs and associated symptoms should be assessed in both the inpatient and outpatient setting. Older patients and patients with lower BMIs, lower ambulatory blood pressures, grade 2 CRS, or a history of hypertension may need closer monitoring.

Abstract
Several drugs are available for the treatment of osteoporosis in postmenopausal women. Over the last decades, most patients requiring pharmacological intervention were offered antiresorptive drugs as first-line therapy, while anabolic agents were considered a last resource for those with therapeutic failure. However, recent randomized trials in patients with severe osteoporosis have shown that anabolic agents reduce fractures to a greater extent than antiresorptive medications. Additionally, evidence indicates that increases in bone mineral density (BMD) are maximized when patients are treated with anabolic agents first, followed by antiresorptive therapy. This evidence is key, considering that greater increases in BMD during osteoporosis treatment are associated with a more pronounced reduction in fracture risk. Thus, international guidelines have recently proposed an individualized approach to osteoporosis treatment based on fracture risk stratification, in which the stratification risk has been refined to include a category of patients at very high risk of fracture who should be managed with anabolic agents as first-line therapy. In this document, the Brazilian Society of Endocrinology and Metabolism and the Brazilian Association of Bone Assessment and Metabolism propose the definition of very high risk of osteoporotic fracture in postmenopausal women, for whom anabolic agents should be considered as first-line therapy. This document also reviews the factors associated with increased fracture risk, trials comparing anabolic versus antiresorptive agents, efficacy of anabolic agents in patients who are treatment naïve versus those previously treated with antiresorptive agents, and safety of anabolic agents.

Abstract
BACKGROUND Impaired cerebral blood flow has been associated with an increased risk of falls. Mean arterial pressure (MAP) and variability in MAP have been reported to affect cerebral blood flow but their relationships to the risk of falls have not previously been reported. METHODS Utilising data from the Aspirin in Reducing Events in the Elderly trial participants, we estimated MAP and variability in MAP, defined as within-individual SD of MAP from baseline and first 2 annual visits. The relationship with MAP was studied in 16 703 participants amongst whom 1539 falls were recorded over 7.3 years. Variability in MAP was studied in 14 818 of these participants who experienced 974 falls over 4.1 years. Falls were confined to those involving hospital presentation. Cox regression was used to calculate hazard ratio and 95% CI for associations with falls. RESULTS Long-term variability in MAP was not associated with falls except amongst frail or prefrail participants using antihypertensive medications. Within this group each 5 mm Hg increase in long-term variability in MAP increased the risk of falls by 16% (hazard ratio, 1.16 [95% CI, 1.02-1.33]). Amongst the antihypertensive drugs studied, beta-blocker monotherapy (hazard ratio, 1.93 [95% CI, 1.17-3.18]) was associated with an increased risk of falls compared with calcium channel blockers. CONCLUSIONS Higher levels of long-term variability in MAP increase the risk of serious falls in older frail and prefrail individuals taking antihypertensive medications. The observation that the relationship was limited to frail and prefrail individuals might explain some of the variability of previous studies linking blood pressure indices and falls.

Abstract
OBJECTIVES This review outlines the normal heart rate and blood pressure response to active standing, the physiological mechanisms governing these, and the effect of ageing on the responses. METHODS A literature search was conducted to identify articles investigating the normal heart rate and/or blood pressure response to standing. RESULTS Heart rate when standing increases and then decreases and recovers to baseline. Blood pressure responses are inverse. Skeletal muscle contraction and the baroreceptor reflex drive this. With ageing, heart rate response attenuates and the initial blood pressure response increases. DISCUSSION Normal heart rate and blood pressure responses are attributed to the baroreceptor reflex and skeletal muscle contraction. Decreased muscle strength and baroreceptor sensitivity are associated with ageing, suggesting a possible benefit in improving skeletal muscle strength to maintain an efficient response. Understanding these responses and their variation with ageing is clinically relevant and may be beneficial in improving rehabilitation outcomes.

Abstract
PURPOSE To determine the nursing staff's knowledge of the proper procedure for measuring orthostatic vital signs. METHODS The Knowledge of Orthostatic Vital Signs Survey was sent via email to direct staff on 31 patient-care units in a large hospital system. RESULTS Eighty percent of the participants were RNs and 12% were unlicensed assistants. Survey results showed that many respondents did not know how to properly size the cuff and were uncertain about the timing of measurements with position changes. Fifty-seven percent of respondents did not correctly identify abnormal findings with regard to the systolic BP, but 80% were aware of the diastolic BP drop in orthostatic hypotension. CONCLUSION This survey identified gaps in the staff's knowledge about the proper procedure for measuring orthostatic vital signs.

Abstract
Orthostatic hypotension is an unusually large decrease in blood pressure on standing that increases the risk of adverse outcomes even when asymptomatic. Improvements in haemodynamic profiling with continuous blood pressure measurements have uncovered four major subtypes: initial orthostatic hypotension, delayed blood pressure recovery, classic orthostatic hypotension, and delayed orthostatic hypotension. Clinical presentations are varied and range from cognitive slowing with hypotensive unawareness or unexplained falls to classic presyncope and syncope. Establishing whether symptoms are due to orthostatic hypotension requires careful history taking, a thorough physical examination, and supine and upright blood pressure measurements. Management and prognosis vary according to the underlying cause, with the main distinction being whether orthostatic hypotension is neurogenic or non-neurogenic. Neurogenic orthostatic hypotension might be the earliest clinical manifestation of Parkinson's disease or related synucleinopathies, and often coincides with supine hypertension. The emerging variety of clinical presentations advocates a stepwise, individualised, and primarily non-pharmacological approach to the management of orthostatic hypotension. Such an approach could include the cessation of blood pressure lowering drugs, adoption of lifestyle measures (eg, counterpressure manoeuvres), and treatment with pharmacological agents in selected cases.

Abstract
BACKGROUND Orthostatic syncope (transient loss of conscious when standing-fainting) is common and negatively impacts quality of life. Many patients with syncope report experiencing fatigue, sometimes with "brain fog", which may further impact their quality of life, but the incidence and severity of fatigue in patients with syncope remain unclear. In this systematic review, we report evidence on the associations between fatigue and conditions of orthostatic syncope. METHODS We performed a comprehensive literature search of four academic databases to identify articles that evaluated the association between orthostatic syncope [postural orthostatic tachycardia syndrome (POTS), vasovagal syncope (VVS), orthostatic hypotension (OH)] and fatigue. Studies were independently screened using a multi-stage approach by two researchers to maintain consistency and limit bias. RESULTS Our initial search identified 2797 articles, of which 13 met our inclusion criteria (POTS n = 10; VVS n = 1; OH n = 1; VVS and POTS n = 1). Fatigue scores were significantly higher in patients with orthostatic syncope than healthy controls, and were particularly severe in those with POTS. Fatigue associated with orthostatic syncope disorders spanned multiple domains, with each dimension contributing equally to increased fatigue. "Brain fog" was an important symptom of POTS, negatively affecting productivity and cognition. Finally, fatigue was negatively associated with mental health in patients with POTS. CONCLUSION In conditions of orthostatic syncope, fatigue is prevalent and debilitating, especially in patients with POTS. The consideration of fatigue in patients with orthostatic disorders is essential to improve diagnosis and management of symptoms, thus improving quality of life for affected individuals.

Abstract
Pharmacotherapy is important in older patients undergoing rehabilitation because such patients, especially those with frailty and physical disabilities, are susceptible to drug-related functional impairment. Drug-related problems include polypharmacy, potentially inappropriate medications (PIMs), and potential prescription omissions. These problems are associated with adverse drug events such as dysphagia, depression, drowsiness, falls and fractures, incontinence, decreased appetite, and Parkinson's syndrome, leading to impaired improvement in activities of daily living (ADL), quality of life (QOL), and nutritional status. Moreover, the anticholinergic burden is associated with impaired physical and cognitive functions. Therefore, pharmacist-centered multidisciplinary pharmacotherapy should be performed to maximize rehabilitation outcomes. Pharmacotherapy includes a review of all medications, the assessment of drug-related problems, goal setting, correction of polypharmacy and PIMs, monitoring of drug prescriptions, and reassessment of drug-related problems. The goal of pharmacotherapy in rehabilitation medicine is to optimize drug prescribing and to maximize the improvement of ADL and QOL as patient outcomes. The role of pharmacists during rehabilitation is to treat patients as part of multidisciplinary teams and as key members of nutritional support teams. In this review, we aim to highlight existing evidence regarding pharmacotherapy in older adults, including drug-related functional impairment and the association between pharmacotherapy and functional, cognitive, and nutritional outcomes among patients undergoing rehabilitation. In addition, we highlight the important role of pharmacists in maximizing improvements in rehabilitation outcomes and minimizing drug-related adverse effects.

Abstract
Purpose of review The management of hypertension in frail older adults remains controversial, as these patients are underrepresented in clinical trials and practice guidelines. Overtreatment may cause harm while undertreatment may lead to greater risk of cardiovascular events. Our research aims to examine this controversy and provide guidance regarding deprescribing decisions in frail older adults. Results Current evidence suggests that there may be minimal cardiovascular benefit and significant harm of antihypertensive medication in the frail older adult population. A minority of hypertension guidelines provide sufficient recommendations for frail older adults, and there are limited tools available to guide clinical decision-making. Conclusion Randomized controlled trials and well-designed observational studies are needed to confirm the benefit-to-harm relationship of antihypertensive medication in frail older adults. Decision tools that comprehensively address antihypertensive deprescribing would be advantageous to help clinicians with hypertension management in this population. Clinicians should engage in shared decision-making with the patient and family to ensure that decisions regarding antihypertensive deprescribing best meet the needs of all involved.

Assessment of Abdominal Constrictor's Forces for Informing Computational Models of Orthostatic Hypotension. MATERIALS 2022; 15:ma15093116.

Abstract
Orthostatic hypotension is defined as a sudden drop in blood pressure upon standing from a sitting or supine position. The prevalence of this condition increases exponentially with age. Nonpharmacological treatments are always the first step in the management of this condition, such as the use of an abdominal constriction belt to optimize the blood volume in the abdomen. A multitude of clinical trials have shown the efficacy of elastic abdominal compression as well as compression using an inflatable bladder; however, there are currently few accessible consumer products that can provide abdominal compression by using an inflatable bladder that ensures the correct amount of pressure is being exerted on the subject. This study serves to quantitatively analyze forces exerted in inflatable abdominal binders, a novel treatment that fits the criterion for a first-line intervention for orthostatic hypotension. Quantitative values aim to indicate both the anatomic regions of the body subjected to the highest pressure by abdominal binding. Quantitative values will also create a model that can correlate the amount of compression on the subject with varying levels of pressure in the inflatable bladder. Inflatable binders of varying levels of inflation are used and localized pressure values are recorded at 5 different vertical points along the abdomen in the midsternal line and midclavicular line, at the locations of the splanchnic veins. These findings indicate both the differences in the compressive force applied through elastic and inflatable binding, as well the regions on the abdomen subject to the highest force load during compression by an abdominal binder. A medical manikin called the iStan Manikin was used to collect data. The pressure values on a manikin were sensed by the JUZO pressure monitor, a special device created for the purpose of measuring the force under compressive garments. The pressure inside the inflatable bladder was extrapolated from a pressure gauge and the pressure was recorded at different degrees of inflation of the belt (mmHG) along two different areas of the abdomen, the midsternal line and the midclavicular line, to discern differences in force exerted on the patient (mmHG). Computational studies on the data from the JUZO pressure monitor as well as the data from the pressure gauge on the inflatable bladder allow us to create a model that can correlate the amount of pressure in the inflatable bladder to the amount of pressure exerted on the belt, thus making sure that the patient is not being harmed by the compressive force. The results of our study indicate that there is no significant difference between the pressures exerted on the midsternal and midclavicular lines of the body by the abdominal binder and that no significant difference exists between the external pressure measured by the inflatable belt and the pressure sensed on the human body by the JUZO sensor; however, we were able to extrapolate an equation that can tell the user the amount of pressure that is actually being exerted on them based on the pressure in the inflatable bladder as recorded by the gauge.

Abstract
Background Orthostatic blood pressure dysregulation, including orthostatic hypotension (OH) and orthostatic hypertension (OHT), is common in the elderly. The association between OH and, to a lesser extent, OHT with geriatric syndromes is controversial and little investigated. Our objective was to assess the association between orthostatic blood pressure dysregulation and geriatric syndromes in an ambulatory outpatient population. Methods This observational study included all outpatients for whom a one-visit comprehensive geriatric assessment was performed during a year. OH was defined as a decrease of at least 20 mmHg in systolic blood pressure (SBP) and/or 10 mmHg in diastolic blood pressure (DBP) after 1 or 3 min of standing. OHT was defined as an increase of more than 20 mmHg in SBP after 1 or 3 min of standing. Comorbidities, drugs regimen, a history of previous falls, nutritional, frailty, functional and cognitive status were compared between patients with OHT or OH and controls (NOR). Results Five hundred thirty patients (mean age: 82.9 ± 5.1 years) were included. 19.6% had an OH and 22.3% an OHT. OHT patients were more frequently female, had more diabetes and a lower resting SBP than patients with NOR. OH patients had a higher resting SBP than NOR. After adjusting for age, sex, resting SBP and diabetes, OHT was associated with a low walking speed (OR = 1.332[1.009–1.758]; p = 0.043) and severe cognitive impairment at MMSe score (OR = 1.629[1.070–1.956]; p = 0.016) compared to NOR. Conversely, OH was associated with a lower grip strength (p = 0.016) than NOR. Conclusion OHT and OH are common in elderly but associated with different geriatric phenotypes.

Abstract
The study investigated the association of orthostatic hypotension (OH) with functional position change and balance in older adults with hypertension. The presence of OH was assessed with intermittent (OH intermittent) and continuous blood pressure (OH continuous) monitoring. The change in functional position was tested with sitting to standing assessment, balance performance using activity specific balance confidence scale (ABC), and timed up and go test (TUG). Testing unilateral and bilateral standing with and without altered sensory inputs was tested using the Humac balance system. ABC, TUG, and standing up time showed no significant association with OH intermittent and OH continuous. A significant association was found between bilateral standing with eyes closed on foam surface for overall stability index and OH intermittent. Older people with hypertension may be routinely examined for OH and appropriate intervention strategies should be included for comprehensive care.

Abstract
BACKGROUND Multimodal analgesia, a key component of enhanced recovery after surgery protocols, emphasizes the use of nonopioid analgesics. Preoperative and postoperative gabapentin is often included within multimodal analgesia because it has been shown to reduce postoperative opioid use. However, the role of gabapentin has been questioned because of concerns of adverse effects, particularly in the elderly. In an effort to better understand the specific role of gabapentin within the context of an established enhanced recovery after surgery protocol, the authors studied the prevalence of its adverse effects in patients undergoing abdominal wall reconstruction. METHODS Following institutional review board approval, a retrospective review of a prospectively collected database of 267 consecutive patients who underwent abdominal wall reconstruction performed by a single surgeon was conducted. Demographic variables; operative details; postoperative analgesic use; the presence of dizziness, lightheadedness, or altered mental status; hypotension; negative Richmond Agitation Sedation Scale scores; and postoperative falls were recorded and analyzed according to postoperative gabapentin administration. RESULTS Two hundred thirteen patients (80 percent) met inclusion criteria, of which 138 (65 percent) received postoperative gabapentin. Postoperative gabapentin use was not associated with dizziness, lightheadedness, or altered mental status; hypotension; negative Richmond Agitation Sedation Scale scores; or falls. Furthermore, even among those aged 65 years or older, postoperative gabapentin use was not significantly associated with these adverse events. CONCLUSIONS In patients undergoing abdominal wall reconstruction, postoperative gabapentin administration was not associated with an increase in adverse effects. Further prospective analysis may better allow the characterization of the adverse effects of perioperative gabapentin. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
Background. Falls as geriatric syndrome in elderly age are associated with high health risks, including serious injury, prolonged hospital stays, and medical and follow-up costs. The prevalence of falls in comorbid elderly patients without hypertension remains uncertain.
Aim. To study the incidence of falls in the comorbid elderly with or without hypertension.
Materials and methods. The study included 5240 outpatients aged 60 and over with three or more chronic diseases treated at Moscow polyclinics with verified diagnoses according to medical records in 20152018. The exclusion criteria were acute illness, exacerbation of chronic diseases, disease decompensation, severe sensory impairment and dementia. Student's t-criterion was used to compare quantitative variables between groups and Fisher's exact test was used to compare binary variables.
Results. The age of study participants was 71.0 0.1 years, 72.4% women. The vast majority of patients (99.3%, n=5202) has been diagnosed with arterial hypertension or essential hypertension, and 0.7% of patients (n=38) had no such diagnoses. The incidence of falls in hypertensive patients was 16.4% (n=857), while 42.1% (n=16) of patients without hypertension reported falls (p=0.00018; odds ratio 3.69; 95% confidence interval 1.807.38).
Conclusion. The paradox of the greater frequency of falls in the group of elderly patients who experienced no blood pressure elevation episodes compared with hypertensive patients has not been fully understood yet and can indicate that the risk of falls in patients who experienced no blood pressure elevation is higher; however, further research is required.

Abstract
BACKGROUND Alzheimer's disease (AD) patients frequently present with orthostatic hypotension. This inability to reflexively increase blood pressure on standing is a serious health concern and increases the risk of stroke and cardiovascular diseases. OBJECTIVE Since there are no clear mechanisms for orthostatic hypotension in human AD, the present study assessed the autonomic changes that could explain this comorbidity in an AD animal model. METHODS We used the established streptozotocin-induced rat model of AD (STZ-AD), which mimics many hallmark symptoms of sporadic AD in humans. Baroreflex responses were analyzed in anesthetized STZ-AD rats using femoral catheterization for blood pressure and heart rate, and autonomic activity was assessed using specific blockers and splanchnic sympathetic nerve recordings. Expression levels of autonomic receptors at the heart were examined using the western blot technique. RESULTS Baroreflex function in STZ-AD showed a blunted heart rate (HR) response to low blood pressure challenges, and the maximal sympathetic nerve activity was reduced. Conversely, HR responses to high blood pressure were similar to control, indicating no change in parasympathetic nerve activity. Under resting conditions, autonomic blockade demonstrated a baseline shift to increased sympathetic tone in STZ-AD. Protein expression levels of beta-1 adrenergic receptor and muscarinic acetylcholine receptor M2 in the heart were unchanged. CONCLUSION Our study provides the first data on the pathological influence of AD on baroreflex function, which primarily affected the sympathetic nervous system in STZ-AD. These results represent the first mechanisms that may correlate with the orthostatic hypotension in human AD.

Abstract
BACKGROUND Orthostatic hypotension (OH) increases the risk of falls and associated morbidity and mortality in elderly. Hence, determining the prevalence of OH and its associated factors is important, especially in understudied LMIC settings. METHODS A community-based cross-sectional study was conducted among randomly selected 240 community-dwelling elderly from Thiruvananthapuram, Kerala. The OH symptoms were assessed by standard clinical measurements and frailty was assessed by modified Fried frailty phenotype. Logistic regression analysis was conducted to assess the factors associated with OH. RESULTS The prevalence of OH and frailty among participants was 9.6 and 29.2 percent respectively. In the first minute, OH was associated with increased odds of falls (OR = 1.97 [95%CI = 1.05, 3.72]). Increase in number of co-morbidities (ORadj = 1.82 [95%CI = 1.36, 2.48]), number of medicines used (ORadj = 1.73 [95%CI = 1.28, 2.34]), and orthostatic intolerance (ORadj = 3.67 [95%CI = 1.13, 11.94]) increased the odds of having OH. Elderly with diabetes (ORadj = 4.81 [95%CI = 1.57, 14.77]), hypertension (ORadj = 4.97 [95%CI = 1.01, 24.46]) and cognitive impairment (ORadj = 5.01 [95%CI = 1.40, 18.51]) were at a higher odds of having OH. CONCLUSIONS OH and frailty are prevalent in community dwelling elderly in Thiruvananthapuram district. Frailty may be a risk factor for OH in the first minute. The number of co-morbidities may be an independent risk factor for OH. Hence, elderly people with comorbidities and cognitive impairment may be actively assessed for OH to prevent falls and associated injuries.

Abstract
The aim of this study was to determine the relationship between the fear of falling/the degree of fear of falling (FoF) and orthostatic hypotension (OH) in older adults. This cross-sectional study was conducted with 314 older outpatients. If the total score of the Falls Efficacy Scale-International scale was 16-19, 20-27 and ≥ 28, it was assumed that there was low FoF, moderate FoF and high FoF, respectively. OH was evaluated for the 1st (OH1) and 3rd (OH3) minutes, after transitioning from the supine position to standing. Participants were aged 65-93 years (mean age 74.2 ± 8.5 years) and 193 (61.5%) were female. Among the FoF groups, significant differences were found for age, gender, education, marital status, who the patient lived with, the history of falling and hypertension, Timed Up-Go test score and hemoglobin levels (p < 0.005). The prevalence of OH1 and OH3 was found to be significantly higher in those with an FoF score of 20 and above than those below 20 (p < 0.005). After adjustment for potential confounders, participants who reported a high FoF had higher risk for OH1 and OH3 (OR 2.14, 95% CI 1.14-4.0, p = 0.017; and OR 2.72, 95% CI 1.46-5.09, p = 0.002, respectively), but those with moderate FoF had no increased risk of having OH compared to low FoF (p > 0.05). There is a close relationship between high FoF and OH in older adults. Therefore, when evaluating an older patient with OH, FoF should be evaluated, or FoF should also be questioned in older patients with OH.

Abstract
INTRODUCTION Multiple sclerosis (MS) is a chronic demyelinating immune mediated disease of the central nervous system. Autonomic dysfunction (AD) is frequently present in persons with MS (pwMS) and increases with disease duration and progression. AREAS COVERED Cardiovascular, genitourinary, and sudomotor autonomic dysfunction in pwMS are reviewed and managing of these disorders is addressed. EXPERT OPINION AD in pwMS can manifest with a myriad of symptoms including cardiovascular, urogenital, and sweating disorders. These symptoms can significantly impact the quality of life of pwMS with poor tolerance of upright position, difficulties in sexual function, and low endurance of physical activity especially in warm environments. Health professionals involved in care of pwMS should possess basic knowledge of the function of the autonomic nervous system and be informed of the way disorders of the autonomic function may manifest in pwMS in order to provide the proper care.

Abstract
Background The objective was to investigate the individual effect and potential interactions of probable rapid eye movement sleep behavior disorder (pRBD) and sleep insufficiency on fall risk among a Chinese elderly population. Methods Community-dwelling population aged 55 years or above were recruited from the Beijing Longitudinal Study on Aging II cohort from 2010 to 2011. Odds ratio (ORs) and 95% confidence intervals (CIs) were estimated using multivariate logistic regression models. Multiplicative and additive interactions between pRBD and sleep insufficiency were examined using likelihood ratio tests and relative excess risk due to interaction (RERI), respectively. Results Among 6891 included participants, 479 experienced at least once fall. pRBD and sleep insufficiency were both independently associated with elevated fall risk. Compared to the elderly without pRBD or sleep insufficiency, pRBD and sleep insufficiency was each associated with a 2.57-fold (OR = 2.57, 95%CI: 1.46–4.31) and 1.45-fold (OR = 1.45, 95%CI: 1.11–1.88) risk of falls individually, while their coexistence was associated with a less-than-additive 17% (OR = 1.17, 95%CI: 0.43–2.63) increased risk of falls. The combination of these two factors demonstrated evidence of a negative interaction on both multiplicative (ratio of ORs = 0.31, 95%CI: 0.10, 0.86) and additive (RERI = − 1.85, 95%CI: − 3.61, − 0.09) scale. Conclusions Our study has provided robust evidence for the adverse effect of pRBD and sleep insufficiency, as well as their negative interaction on increasing fall risk in a Chinese elderly population.

Abstract
Introduction: Falls, which have a higher incidence and mortality due to accidental injuries, are a major global health challenge. The effects of lifestyle factor, health indicator, psychological condition, and functional status interventions on the risk of falls are unknown and the conventional regression model would not adjust for the confounders. This study aimed to evaluate the 4-year risk of falls on the basis of these hypothetical interventions among Chinese older adults. Methods: Data were obtained from 9,692 aged 65 years and over older adults in the China Health and Retirement Longitudinal Study wave, from 2011 to 2015. We used the parametric g-formula to evaluate the risk of falls on the basis of independent hypothetical interventions of sleep duration, social activities, smoking status, drinking status, body mass index (BMI), systolic blood pressure (SBP), vision, depression, activities of daily living (ADL), and their different joint intervention combinations. Results: During the follow-up of 4 years, we documented 1,569 falls. The observed risk of falls was 23.58%. The risk ratios (95% confidence intervals [CIs]) of falls under the intensive hypothetical interventions on increasing sleep duration, participating in more social activities, quit smoking and drinking, reducing BMI and SBP, better vision, alleviating depressive symptoms, and improving ADL capability were 0.93 (0.87–0.96), 0.88 (0.79–0.92), 0.98 (0.95–1.03), 0.97 (0.95–1.02), 0.92 (0.86–1.03), 0.93 (0.87–1.04), 0.86 (0.74–0.91), 0.91 (0.85–0.96), and 0.79 (0.74–0.85), respectively. The feasible and intensive joint hypothetical intervention reduced the 4-year fall risk by 22% (95% CI: 0.52–0.91) and 33% (95% CI: 0.56–0.72), respectively. Conclusions: Hypothetical interventions for increasing sleep duration, participating in more social activities, better vision, alleviating depressive symptoms, and improving ADL capability help protect older adults from falls. Our findings suggest that a combination of lifestyle factors, health indicators, psychological conditions, and functional status may prove to be an effective strategy for preventing falls among older adults.

Abstract
High blood pressure is a risk factor for cardiovascular morbidity and mortality, as well as cognitive decline and loss of autonomy in the elderly and old age. Randomized clinical trials (RCTs) in populations of older patients living at home with low comorbidity and preserved autonomy indicate the benefit of lowering elevated blood pressure in patients over 80 years of age. Older patients with senile asthenia, loss of autonomy and other geriatric problems were excluded from RCTs, and observational studies in these groups of patients indicate an increase in morbidity and mortality with lower blood pressure and antihypertensive therapy. Obviously, in very elderly patients, a universal strategy for the treatment of arterial hypertension cannot be applied due to the significant heterogeneity of their functional status. The geriatric approach to the management of arterial hypertension in older patients involves an assessment of the functional status, the presence of senile asthenia, and the degree of autonomy for the choice of antihypertensive therapy tactics.

Abstract
OBJECTIVES Orthostatic hypotension (OH) and orthostatic intolerance symptoms are common in older community-dwelling adults and are associated with reduced quality of life and detrimental health outcomes. This study aimed to determine the prevalence, co-occurrence and determinants of OH and orthostatic intolerance symptoms in geriatric rehabilitation inpatients. DESIGN Observational, longitudinal cohort, "REStORing the health of acutely unwell adulTs" (RESORT). SETTING AND PARTICIPANTS Geriatric rehabilitation inpatients (n = 1505) of a tertiary teaching hospital in Melbourne, Australia. METHODS OH was defined as a drop in systolic blood pressure by ≥20 mm Hg and/or diastolic blood pressure by ≥10 mm Hg within three 3 of moving from supine to a standing or sitting position. Symptoms were recorded following the 3 minutes. Determinants included sociodemographics, reason for admission, cognitive health, nutritional status, physical performance, frailty, morbidity, medication use, length of stay (LOS), and number of geriatric conditions. Independent t-tests, Mann-Whitney U tests or χ2 tests were used to analyze differences between inpatients with and without OH and symptoms. Logistic regression analyses were used to ascertain the determinants. RESULTS OH and orthostatic intolerance symptoms were prevalent in 19.8% (standing: 21.4%, sitting: 18.2%) and 22.6% (standing: 25.0%, sitting: 20.2%) of inpatients, respectively. Symptoms were reported by 32.8% of inpatients with OH and 20.1% without OH. Higher number of comorbidities and geriatric conditions, low functional independence, and longer LOS were determinants of OH. Female gender, higher number of morbidities and geriatric conditions, low functional independence, depression risk, poor physical performance, musculoskeletal and "other" reasons for admission, and long LOS during geriatric rehabilitation were determinants of symptoms. CONCLUSIONS AND IMPLICATIONS OH and orthostatic intolerance symptoms occur in one-fifth of geriatric rehabilitation inpatients, however, the co-occurrence is low and determinants differ. Poorer health in patients with orthostatic intolerance symptoms highlights the need to assess symptoms in clinical practice, independent of an OH diagnosis.

Abstract
OBJECTIVES To assess the prevalence of orthostatic hypotension (OH) and the association of OH with the risk of falls among community-dwelling older adults with a previous fall. DESIGN Longitudinal study. SETTING AND PARTICIPANTS The subjects (n = 561) were participants in fall prevention conducted in western Finland. METHODS Blood pressure (BP) was measured in supine position and at 30 seconds and 3 minutes after standing. The participants were divided according to the consensus definition to an OH group (OHG) and a non-OH group (non-OHG). Falls were recorded by fall diaries during 12 months. Falls requiring treatment were gathered from health center and hospital registers during 12 and 36 months. RESULTS The prevalence of OH was 23.4% (30 seconds) and 7.3% (3 minutes). The 30-second measurement showed that the incidence of falls and that of falls requiring treatment were significantly higher in OHG compared with non-OHG during 12 months. After adjustments, the incidence of falls remained higher in all 5 adjusted models whereas that of falls requiring treatment remained higher only after adjustment for functional balance. The 3-minute measurement showed that the incidence of falls was higher in OHG compared with non-OHG during 12 months and remained higher after adjustments for functional balance and for age and functional balance. During the 36-month follow-up, OH measured at 30 seconds or 3 minutes after standing was not associated with the occurrence of falls leading to treatment. CONCLUSIONS AND IMPLICATIONS OH at 30 seconds or 3 minutes after standing is associated with a greater risk for falling within 12 months in older adults. The 30-second blood pressure measurement is more reliable to detect the risk than the 3-minute measurement. The results support the usability of 30-second measurement in determining OH and the risk for falling among older persons.

Abstract
BACKGROUND Orthostatic hypotension (OH) is a clinical sign associated with severe adverse health outcomes in older adults. It has been reported to be common in patients with Alzheimer's disease (AD). The present meta-analysis aimed to investigate the prevalence and risk of OH in AD patients. METHODS English-language articles published from January 1990 to August 2020 were searched in PubMed, ScienceDirect, Cochrane, and Web of Science with the keywords "Alzheimer" and "autonomic dysfunction" or "dysautonomia" or "postural hypotension" or "orthostatic hypotension." All prospective clinical studies (case-control, cohort, and cross-sectional studies, and randomized controlled trials) that were regarded as pertinent were included in this study. For quality assessment, the Newcastle-Ottawa Scale was used. Odds ratios (OR) and risk ratios (RR) were extracted with 95% confidence intervals (CI) and combined using the random effects model after logarithmic transformation. The prevalence in the AD patients was also combined using the random effects model. RESULTS The meta-analysis involved 11 studies (7 case-control and 4 case series) to assess the risk of OH in AD. It was found that AD increased the risk of OH with an RR of 1.98 (95% CI: 0.97-4.04) and an OR of 2.53 (95% CI:1.10-5.86) compared to healthy controls, and OH was present in 28% (95% CI: 0.17-0.40) of 500 AD patients. CONCLUSION There is an elevated risk of OH in AD by nearly 2.5-fold. Therefore, the evaluation of postural blood pressure changes should definitely be among the follow-up and treatment goals of AD.
