Abstract
INTRODUCTION Anticholinergic or ß-3 agonist use following robotic simple prostatectomy (RASP) is not well described. We describe rates of antispasmodic use following RASP and identify potential predictors of medication use. MATERIALS AND METHODS A retrospective review of all RASP patients from 2/2016 - 1/2020 was conducted. Patients with no preoperative International Prostate Symptom Score (IPSS) were excluded. Demographics, clinical data, and postoperative medication use were collected by electronic medical record review. Multivariable logistic regression analysis using a priori variables was performed to identify independent factors associated with antispasmodic use. RESULTS A total of 255 patients underwent RASP at a mean age of 70.0 years ± 7.3 and mean body mass index (BMI) of 28.6 kg/m2 ± 5.0. Median preoperative prostate volume was 132.3 cc ± 45.0. Rates of preoperative diabetes, obstructive sleep apnea (OSA), smoking and alcohol use were 19.6%, 6.3%, 3.1%, and 11.8% respectively; 8.6% of patients (n = 22) initiated antispasmodics at a median of 2.5 months (IQR 1.3-4.2) postoperatively. Median duration of antispasmodic use was 6.5 months (IQR 1.7-14.7). Mirabegron was most commonly prescribed (31.8%). On multivariable logistic regression analysis, OSA was independently associated with postoperative antispasmodic use (OR 8.13, 95% CI 2.02-32.67, p = 0.003); 68.8% of OSA patients were treated with continuous positive airway pressure (CPAP). Treatment was not significantly associated with postoperative antispasmodic use (p = 0.61). CONCLUSION Patients with OSA are over 8 times more likely to require antispasmodic medications following RASP in the short term. These patients may benefit from more tailored preoperative counseling.

Abstract
Objective To evaluate the long-term safety and efficacy of indacaterol/glycopyrronium (IND/GLY) in patients with chronic obstructive pulmorary disease (COPD) in a real-world setting in Japan. Methods This 52-week, multicentre, post-marketing surveillance conducted in Japan between December 2013 and August 2019 included patients using IND/GLY for the first time to relieve airway obstructive disorder-related symptoms. Safety outcomes included the incidence of adverse events (AEs), serious AEs (SAEs), adverse drug reactions (ADRs), and serious ADRs during the 52-week period. The incidence of priority variables, including cardiovascular/cerebrovascular (CCV) AEs, β-adrenergic-related or anticholinergic AEs and cough, was also assessed. Safety outcomes were also evaluated in elderly patients. Efficacy outcomes included a physician's global assessment, COPD assessment test (CAT) and lung function test. Results Of the 1,167 patients registered, 1,108 were included in the safety and efficacy analysis. In the safety analysis population, the incidence of AEs was 13.54%, that of SAEs was 4.69%, that of ADR was 3.61%, and that of serious ADRs was 0.36% over 52 weeks. CCV AEs, β-adrenergic-related and anticholinergic AEs and cough were reported as 2.62%, 1.99% and 0.63%, respectively. The physician's global assessment showed that the overall response rate at the last assessment was 74.19%. The mean (95% confidence interval) CAT scores decreased from the start of treatment to Week 52 with IND/GLY [-6.9 (-7.8 to -6.1)]. The lung function (FEV1 and FVC) improved over time from the start of IND/GLY to Week 52. Conclusion IND/GLY demonstrated a good long-term safety profile in a real-world setting in Japanese patients with COPD, with beneficial effects in terms of the lung function and symptoms in clinical use.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 19:ijerph19010423. [PMID: 35010682 PMCID: PMC8744764 DOI: 10.3390/ijerph19010423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 12/24/2021] [Accepted: 12/28/2021] [Indexed: 11/16/2022]
Abstract
AIM The objective of this study was to assess the impact of a collaborative therapeutic optimization program on the rate of potentially inappropriate prescription of drugs with anticholinergic properties in nursing homes. METHODS Quasi-experimental study in 37 nursing homes in France. The intervention included the use of quality indicators for prescriptions combined with educational sessions and dedicated materials for nursing home staff (unlimited access to study material for staff, including nurses, general practitioners, pharmacists). Indicators were calculated based on routine data collected from an electronic pill dispenser system. The primary outcome was the presence of at least one prescription containing ≥1 drug from a list of 12 drugs with anticholinergic properties. A difference-in-differences analysis was conducted at 18 months as well as propensity score weighting to minimize any potential indication bias. A generalized estimating equation model estimated the probability of being prescribed at least one target drug at any time during a 9-month period for each resident. RESULTS In total, 33 nursing homes (intervention group: n = 10; control group: n = 23) were included, totalling 8137 residents. There was a decrease in the use of drugs with anticholinergic properties over time in both groups, as well as a decline in the intervention group compared to the control group (Odds Ratio: 0.685, 95% CI: 0.533, 0.880; p < 0.01) that was attributable to the intervention. An estimated 49 anticholinergic properties drug prescriptions were avoided by the intervention. CONCLUSION This study found that an intervention based on indicators derived from routine prescription data was effective in reducing use of drugs with anticholinergic properties prescriptions in nursing homes.

Abstract
Intestinal spasms are violent contractions that occur in the intestine, which cause discomfort to people who have them. Medicinal plants are widely used in traditional Moroccan medicine to treat these problems, among these being Artemisia campestris L. This study aims to evaluate the relaxant and antispasmodic effects of an aqueous extract of this plant (ACAE). It was performed in vitro on isolated segments of both isolated rat and rabbit jejunum mounted in an organ bath and tension recordings made via an isotonic transducer. ACAE caused a myorelaxant effect on baseline rabbit jejunum contractions in a dose-dependent and reversible manner with an IC50 of 1.52 ± 0.12 mg/ml. This extract would not act via adrenergic receptors pathway. On the other hand, the extract caused a dose-dependent relaxation of the jejunum tone in rat jejenum segments pre-contracted with either Carbachol (CCh; 10-6 M) or high K+ (KCl 75 mM) with an IC50 = 0.49 ± 0.02 mg/ml and 0.36 ± 0.02 mg/ml respectively. In the presence of different doses of the extract, the maximum response to CCh and CaCl2 was significantly reduced. This demonstrates that ACAE acts on both muscarinic receptors and voltage-dependent calcium channels. Thus, the plant extract acted on both muscarinic and nicotinic receptors and acts on the guanylate cyclase pathway, but not the nitric oxide pathway. These results indicate the mechanism by which Artemisia campestris L. acts as an effective antispasmodic agent in traditional Moroccan medicine.

Abstract
PURPOSE The clinician treating patients with neurogenic lower urinary tract dysfunction (NLUTD) needs to balance a variety of factors when making treatment decisions. In addition to the patient's urologic symptoms and urodynamic findings, other issues that may influence management options of the lower urinary tract include cognition, hand function, type of neurologic disease, mobility, bowel function/management, and social and caregiver support. This Guideline allows the clinician to understand the options available to treat patients, understand the findings that can be seen in NLUTD, and appreciate which options are best for each individual patient. This allows for decisions to be made with the patient, in a shared decision-making manner, such that the patient's quality of life can be optimized with respect to their bladder management. MATERIALS AND METHODS A comprehensive search for studies assessing patients undergoing evaluation, surveillance, management, or follow-up for NLUTD was conducted from January 2001 through October 2017 and was rerun in February 2021 to capture newer literature. The primary search returned 20,496 unique citations. Following a title and abstract screen, full texts were obtained for 3,036 studies. During full-text review, studies were primarily excluded for not meeting the PICO criteria. One hundred eight-four primary literature studies met the inclusion criteria and were included in the evidence base. RESULTS This guideline was developed to inform clinicians on the proper evaluation, diagnosis, and risk stratification of adult patients with NLUTD and the non-surgical and surgical treatment options available. Additional statements on urinary tract infection and autonomic dysreflexia were developed to guide the clinician. CONCLUSIONS NLUTD patients may undergo non-surgical and surgical treatment options depending on their level of risk, symptoms, and urodynamic findings. Appropriate follow-up, primarily based on their risk stratification, must be maintained after treatment.

Abstract
PURPOSE Benign prostatic hyperplasia (BPH) is a histologic diagnosis describing proliferation of smooth muscle and epithelial cells within the prostatic transition zone. The prevalence and severity of lower urinary tract symptoms (LUTS) in aging men are progressive and impact the health and welfare of society. This revised Guideline provides a useful reference on effective evidence-based management of male LUTS/BPH. See the accompanying algorithm for a summary of the procedures detailed in the Guideline (figures 1 and 2). MATERIALS AND METHODS The Minnesota Evidence Review Team searched Ovid MEDLINE, Embase, Cochrane Library, and AHRQ databases to identify eligible English language studies published between January 2008 and April 2019, then updated through December 2020. Search terms included Medical Subject Headings (MeSH) and keywords for pharmacological therapies, drug classes, and terms related to LUTS or BPH. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, information is provided as Clinical Principles and Expert Opinions (table 1). RESULTS Nineteen guideline statements pertinent to evaluation, work-up, and medical management were developed. Appropriate levels of evidence and supporting text were created to direct both primary care and urologic providers towards streamlined and suitable practices. CONCLUSIONS The work up and medical management of BPH requires attention to individual patient characteristics, while also respecting common principles. Clinicians should adhere to recommendations and familiarize themselves with standards of BPH management.

Abstract
Expression of bronchodilatory β2-adrenoceptors and bronchoconstrictive muscarinic M3-receptors alter with airway size. In COPD, (a combination of) β2-agonists and muscarinic M3-antagonists (anticholinergics) are used as bronchodilators. We studied whether differential receptor expression in large and small airways affects the response to β2-agonists and anticholinergics in COPD. Bronchoprotection by indacaterol (β2-agonist) and glycopyrrolate (anticholinergic) against methacholine- and EFS-induced constrictions of large and small airways was measured in guinea pig and human lung slices using video-assisted microscopy. In guinea pig lung slices, glycopyrrolate (1, 3 and 10 nM) concentration-dependently protected against methacholine- and EFS-induced constrictions, with no differences between large and small intrapulmonary airways. Indacaterol (0.01, 0.1, 1 and 10 μM) also provided concentration-dependent protection, which was greater in large airways against methacholine and in small airways against EFS. Indacaterol (10 μM) and glycopyrrolate (10 nM) normalized small airway hyperresponsiveness in COPD lung slices. Synergy of low indacaterol (10 nM) and glycopyrrolate (1 nM) concentrations was greater in LPS-challenged guinea pigs (COPD model) compared to saline-challenged controls. In conclusion, glycopyrrolate similarly protects large and small airways, whereas the protective effect of indacaterol in the small, but not the large, airways depends on the contractile stimulus used. Moreover, findings in a guinea pig model indicate that the synergistic bronchoprotective effect of indacaterol and glycopyrrolate is enhanced in COPD.

Abstract
Impaired thermoregulation and heat intolerance may be intrinsic to autonomic dysfunction in Parkinson's disease due to disturbances in perspiration regulation. Thermoregulatory impairment leading to hyperthermia/heatstroke can be accentuated with the usage of anticholinergics, which block the ability to sweat. Oxybutynin chloride is one of the most used anticholinergic agents in clinical practice for the management of detrusor hyperreflexia secondary to neurogenic bladder dysfunction and is often used in the setting of Parkinson's disease. We present a rare instance of oxybutynin-induced heatstroke in an elderly patient with Parkinson's disease.

Abstract
NONE Narcolepsy type 1 is characterized by excessive daytime sleepiness and cataplexy, as well as hypocretin deficiency. Cataplexy (the loss of voluntary postural muscle tone, often in response to emotional stimuli) is one of the most disabling features and is associated with significant social impairment and risk of injury. Cataplexy is usually alleviated by antidepressants sodium oxybate and pitolisant. In this case report, we describe three patients with severe, drug-resistant cataplexy who experienced a dramatic improvement when treated with tropatepine, an anticholinergic muscarinic antagonist (commonly used to prevent neuroleptic-induced parkinsonism) after the usual treatments had failed. The single side effect was mild mouth dryness. In addition to providing a new therapeutic option for resistant cataplexy, this benefit supports a role of cholinergic muscarinic transmission in rapid eye movement sleep atonia.

Abstract
OBJECTIVE To test the impact of a multicomponent behavioral intervention to reduce the use of high-risk anticholinergic medications in primary care older adults. DESIGN Cluster-randomized controlled trial. SETTING AND PARTICIPANTS Ten primary care clinics within Eskenazi Health in Indianapolis. INTERVENTION The multicomponent intervention included provider- and patient-focused components. The provider-focused component was computerized decision support alerting of the presence of a high-risk anticholinergic and offering dose- and indication-specific alternatives. The patient-focused component was a story-based video providing education and modeling an interaction with a healthcare provider resulting in a medication change. Alerts within the medical record triggered staff to play the video for a patient. Our design intended for parallel, independent priming of both providers and patients immediately before an outpatient face-to-face interaction. MEASUREMENT Medication orders were extracted from the electronic medical record system to evaluate the prescribing behavior and population prevalence of anticholinergic users. The intervention was introduced April 1, 2019, through March 31, 2020, and a preintervention observational period of April 1, 2018, through March 31, 2019, facilitated difference in difference comparisons. RESULTS A total of 552 older adults had visits at primary care sites during the study period, with mean age of 72.1 (SD 6.4) years and 45.3% African American. Of the 259 provider-focused alerts, only three (1.2%) led to a medication change. Of the 276 staff alerts, 4.7% were confirmed to activate the patient-focused intervention. The intervention resulted in no significant differences in either the number of discontinue orders for anticholinergics (intervention: two additional orders; control: five fewer orders, p = 0.7334) or proportion of the population using anticholinergics following the intervention (preintervention: 6.2% and postintervention: 5.1%, p = 0.6326). CONCLUSION This multicomponent intervention did not reduce the use of high-risk anticholinergics in older adults receiving primary care. Improving nudges or a policy-focused component may be necessary to reduce use of high-risk medications.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disorder that is increasingly viewed as a complex multi-dimensional disease without effective treatments. Recent randomized, placebo-controlled studies have shown volume losses of ~0.7% and ~3.5% per year, respectively, in the basal cholinergic forebrain (CBF) and hippocampus in untreated suspected prodromal AD. One year of donepezil treatment reduced these annualized rates of atrophy to about half of untreated rates. Similar positive although variable results have also been found in volumetric measurements of the cortex and whole brain in patients with mild cognitive impairment as well as more advanced AD stages after treatments with all three currently available acetylcholinesterase (AChE) inhibitors (donepezil, rivastigmine, and galantamine). Here we review the anti-neurodegenerative benefits of AChE inhibitors and the expected parallel disease-accelerating impairments caused by anticholinergics, within a framework of the cholinergic hypothesis of AD and AD-associated loss of nerve growth factor (NGF). Consistent with the "loss of trophic factor hypothesis of AD," we propose that AChE inhibitors enhance acetylcholine-dependent release and uptake of NGF, thereby sustaining cholinergic neuronal viability and thus slowing AD-associated degeneration of the CBF, to ultimately delay dementia progression. We propose that improved cholinergic therapies for AD started early in asymptomatic persons, especially those with risk factors, will delay the onset, progression, or emergence of dementia. The currently available competitive and pseudo- irreversible AChE inhibitors are not CNS-selective and thus induce gastrointestinal toxicity that limits cortical AChE inhibition to ~30% (ranges from 19% to 41%) as measured by in vivo PET studies in patients undergoing therapy. These levels of inhibition are marginal relative to what is required for effective symptomatic treatment of dementia or slowing AD-associated neurodegeneration. In contrast, because of the inherently slow de novo synthesis of AChE in the CNS (about one-- tenth the rate of synthesis in peripheral tissues), irreversible AChE inhibitors produce significantly higher levels of inhibition in the CNS than in peripheral tissues. For example, methanesulfonyl fluoride, an irreversible inhibitor reduces CNS AChE activity by ~68% in patients undergoing therapy and ~80% in cortical biopsies of non-human primates. The full therapeutic benefits of AChE inhibitors, whether for symptomatic treatment of dementia or disease-slowing, thus would benefit by producing high levels of CNS inhibition. One way to obtain such higher levels of CNS AChE inhibition would be by using irreversible inhibitors.

Abstract
AIM To determine whether oral potassium chloride (KCI) therapy with concomitant anticholinergic exposure among hospitalized patients is associated with an excess risk for upper gastrointestinal bleeding (UGIB). METHODS A retrospective controlled study among hospitalized patients between January 2007 and April 2019 who were treated with oral KCI. Patients were divided into two groups: with or without concomitant exposure to agents with anticholinergic activity. Outcome was defined as any UGIB. RESULTS The final sample included 13 728 subjects who received oral KCI treatment, of them 3542 (25.8%) had at least one documented overlap with an anticholinergic agent. Mean age was 67.6 (±17.2) and 6893 (50.2%) were females. Median KCI dose was 2.4 g (interquartile range [IQR] 1.2-5.4, n = 9416) with the majority (90.4%) being treated with the wax-matrix form (Slow-K). Twenty-six (0.2%) patients experienced an UGIB event. Univariate analysis demonstrated a significantly higher rate of UGIB among patients concomitantly treated with oral KCI and anticholinergics (0.3%) compared to those without anticholinergic exposure (0.1%, P = 0.018), with median 7 days (IQR 3-16.8) from first KCI dose to bleeding event. Multivariate analysis demonstrated that concomitant anticholinergic exposure (Odds Ratio 2.48, 95% Confidence Interval 1.11-6.51, P = 0.022) and anticoagulation treatment among patients with hemato-oncologic disease (OR 6.61, 95% CI 1.96-22.25, P = 0.002) were significantly associated with UGIB. CONCLUSION Hospitalized patients treated concomitantly with oral KCI and anticholinergic agents have significantly increased risk for UGIB.

Abstract
The currently approved cholinesterase inhibitors (donepezil, rivastigmine, and galantamine) produce gastrointestinal toxicity which limits dosing to that which produces only about 25% to 35% CNS cholinesterase inhibition in Alzheimer's disease patients undergoing treatment, below the minimum therapeutic target of about 40% to 50% CNS inhibition considered necessary to treat cognitive impairment. A recent strategy for producing high-level CNS acetylcholinesterase (AChE) inhibition (50% or higher) is to co-administer a muscarinic anticholinergic with the AChE inhibitor to block the dose-limiting cholinergic overstimulation of the gastrointestinal system, allow more robust AChE inhibition in the CNS, and improve efficacy in the treatment of Alzheimer's disease. Unfortunately, most common muscarinic anticholinergics, including solifenacin, readily penetrate the CNS and are directly associated with long-term exacerbation of the underlying neuropathology of Alzheimer's disease and increased brain atrophy. The co-administration of an anticholinergic with an AChE inhibitor is a rational strategy for improving efficacy in the symptomatic treatment of dementia, but there are significant long-term risks that have not yet been considered. For long-term safety against accelerating the underlying disease processes in Alzheimer's disease, anticholinergics used to increase the tolerability of AChE inhibitors should not penetrate, or have very limited penetration, of the blood-brain barrier. Neurotrophic-mediated mechanisms by which cholinergic drugs may affect neurodegeneration in Alzheimer's disease are explored and improved treatment options are suggested.

Abstract
BACKGROUND & AIMS A unique motor response to sustained esophageal distension, repetitive antegrade contractions (RACs), is observed using functional luminal imaging probe (FLIP) panometry. However, physiologic mechanisms related to this response are unexplored. This study aimed to evaluate the impact of cholinergic inhibition with atropine on the esophageal contractile response to sustained distention, including RACs, among healthy volunteers. METHODS 8 asymptomatic volunteers (ages 22-45) were evaluated in a crossover study design with 16-cm FLIP positioned across the esophagogastric junction and distal esophagus during sedated upper endoscopy. The FLIP study involving stepwise volumetric distension was performed twice in each subject, at baseline and again after atropine (15 mcg/kg) was administered intravenously. FLIP panometry was analyzed to assess the contractile response to distension. RESULTS Antegrade contractions, lumen-occluding contractions, and a RAC pattern were observed in 8/8, 8/8, and 7/8(88%) subjects, respectively, at baseline and in 5/8 (63%), 2/8 (25%) and 2/8 (25%) subjects after atropine. The rate of contractions in the RAC pattern was similar (6-7 contractions per minute) before and after atropine. Compared with the baseline study, distension-induced contractility was triggered at higher fill volumes after atropine. FLIP pressures were lower in response to volumetric filling after atropine than at baseline. CONCLUSIONS The vigor and triggering of the esophageal contractile response to distension is reduced by cholinergic inhibition in asymptomatic controls. The observation that the rate of contractions did not change when patients developed repetitive contractile responses suggests that this rate is not modified by cholinergic inhibition once contractility is triggered.

The anticholinergic effect on cognition (AEC) scale-Associations with mortality, hospitalisation and cognitive decline following dementia diagnosis. Int J Geriatr Psychiatry 2020; 35:1069-1077.

Abstract
OBJECTIVES To investigate associations between central anticholinergic burden (determined through the anticholinergic effect on cognition [AEC] scale) and mortality, hospitalisation and cognitive decline in patients with dementia. METHODS The South London and Maudsley NHS Foundation Trust (SLaM) Clinical Records Interactive Search (CRIS) application was used to identify patients with a first diagnosis of dementia. Medication exposure was extracted through a natural language processing algorithm, allowing for calculations and comparisons of AEC scores. Data were linked to national mortality and hospitalisation data sources, and serially recorded Mini-Mental State Examination (MMSE) scores were used to investigate cognitive decline. RESULTS We identified 14 093 patients with dementia, 60.7% were female and the mean age at diagnosis was 79.8 years. Patients for whom a review of their medication was indicated (AEC score ≥ 2 for any individual drug or total AEC score ≥ 3) had an increased risk of mortality (hazard ratio 1.07; 95% confidence interval [CI]: 1.01-1.15) and emergency hospitalisation (1.10; 95% CI: 1.04-1.17), but there were no associations with duration of hospitalisation. Cognitive trajectory analyses showed that this exposure group had lower MMSE scores at diagnosis and a sharper increase in MMSE scores over the subsequent 6 months, but similar slopes for the 6 to 36 months period compared to the remainder of the sample. CONCLUSIONS Patients with dementia receiving medication with high central anticholinergic activity appear to have worse prognosis in terms of mortality and hospitalisation risk, but have, primarily, acutely impaired cognitive function, rather than longer-term differences in cognitive decline.

Abstract
Objective To examine the urodynamic effects of fesoterodine on neurogenic detrusor overactivity and/or low compliance bladder. Methods A total of 77 patients (52 men, 25 women; aged 61.6 ± 20.3 years) were given fesoterodine 4–8 mg/day and prospectively followed for 12 weeks. The primary end‐point variable was change in the maximum cystometric capacity on urodynamic study. The secondary end‐point was to assess the number of patients whose neurogenic detrusor overactivity disappeared, and the changes in the urodynamic parameters, lower urinary tract symptoms questionnaires and the 3‐day frequency volume chart parameters after the treatment. Results A total of 13 patients (16.9%) withdrew because of adverse events (dry mouth or blurred vision), and four patients dropped out for unknown reasons. Finally, 60 patients completed the study. Bladder capacity at first desire to void, maximum cystometric capacity and bladder compliance increased by 29.2 mL, 79.9 mL and 22.2 mL/cm H2O, respectively, showed statistical significance (P = 0.026, P < 0.001 and P < 0.001). Neurogenic detrusor overactivity disappeared in 12 of 51 patients (23.5%), and a significant increase was observed in bladder capacity at first involuntary contraction (P < 0.001), and a significant decrease was observed in maximum detrusor contraction (P < 0.001). In patients with low compliance bladder (with detrusor underactivity without neurogenic detrusor overactivity; n = 9), maximum cystometric capacity and bladder compliance increased significantly (P = 0.003 and P = 0.006, respectively). Overactive bladder symptom score, International Consultation on Incontinence Questionnaire–Short Form, most items of King’s Health Questionnaire, and the number of urgency episodes and leaks in a day decreased significantly after treatment. Conclusions Fesoterodine seems to be a valid treatment option for neurogenic detrusor overactivity and/or low compliance bladder in neurogenic bladder patients.

Abstract
Objectives The present study was designed to investigate the effectiveness of trihexyphenidyl, a central anticholinergic drug, in preventing the post-traumatic stress disorder (PTSD) symptoms in a mouse model. Methods Mice were subjected to underwater trauma stress for 30 s on day 1 followed by three situational reminders (3rd, 7th and 14th day). Thereafter, the behavioral alterations including freezing behavior were noted on 21st day. The serum corticosterone levels were measured as a biochemical marker of trauma. Elevated plus maze test was done on day 1 and day 2 to assess the memory formation following exposure to trauma. Results Trauma and situational reminders were associated with a significant development of behavioral changes and freezing behavior on the 21st day. Moreover, there was also a significant decrease in the serum corticosterone levels. A single administration of trihexyphenidyl (2 and 5 mg/kg) significantly restored trauma associated-behavioral changes and serum corticosterone levels. Moreover, it significantly increased the transfer latency time on day 2 following stress exposure in comparison to normal mice suggesting the inhibition of memory formation during trauma exposure. Trihexyphenidyl also led to significant reduction in freezing behavior in response to situational reminders again suggesting the inhibition of formation of aversive fear memory. Conclusion The blockade of central muscarinic receptors may block the formation of aversive memory during the traumatic event, which may be manifested in form of decreased contextual fear response during situational reminders. Central anticholinergic agents may be potentially useful as prophylactic agents in preventing the development of PTSD symptoms.

Abstract
BACKGROUND It is recommended that anticholinergic medication is avoided in older people, especially those with cognitive impairment. OBJECTIVE To investigate anticholinergic load (ACL) over time in older primary care patients with and without cognitive impairment. METHODS Community-dwelling general practice patients at baseline (n = 1768), at year one (n = 1373) and a restricted cohort (with possible or definite cognitive impairment) at year two (n = 370) had medication regimens documented by a research nurse during a home visit. Anticholinergic medicines were categorized as levels 1-3 (low-high potency) and summed for each participant as a measure of their ACL. RESULTS Most participants had no change in ACL over time, but there was some turnover in the anticholinergic medications used. The mean change in ACL was 0.012 ± 0.99 from baseline to 12 months and -0.04 ± 1.3 from baseline to 24 months. Cardiovascular drugs were the most commonly used level 1 anticholinergics, followed by antidepressants and opioids. Antidepressants and urologicals were the most commonly used level 3 anticholinergics. The rate of anticholinergic deprescribing was equivalent to the rate of anticholinergic initiation, and commonly involved the level 1 drugs warfarin, furosemide and temazepam, and the level 3 drugs amitriptyline and oxybutynin. People with dementia had a higher ACL at baseline and year one compared with other participants. CONCLUSION ACL of community-dwelling older people was very stable over time. This may represent lost opportunities for deprescribing as well as potentially inappropriate prescribing, particularly in those with cognitive impairment.

Abstract
Anticholinergic drugs can be used as a treatment for many diseases. However, anticholinergic drugs are also known for their cognition-related side effects. Recently, there has been an increasing number of reports indicating a positive association between exposure to anticholinergic drugs and Alzheimer's disease (AD). Our novel study provides evidence of interactions between two representative anticholinergic drugs [Chlorpheniramine (CPM), a common antihistamine, and Trazodone (TRD), an antidepressant] with neuroprotective amyloid-beta (Aβ) chaperone, lipocalin-type prostaglandin D synthase (L-PGDS) and the amyloid beta-peptide (1–40). Here, we demonstrate that CPM and TRD bind to L-PGDS with high affinity where chlorpheniramine exhibited higher inhibitory effects on L-PGDS as compared to Trazodone. We also show that the interactions between the drug molecules and Aβ(1–40) peptides result in a higher fibrillar content of Aβ(1–40) fibrils with altered fibril morphology. These altered fibrils possess higher cytotoxicity compared to Aβ(1–40) fibrils formed in the absence of the drugs. Overall, our data suggest a mechanistic link between exposure to anticholinergic drugs and increased risk of Alzheimer's disease via inhibition of the neuroprotective chaperone L-PGDS and direct modification of Aβ amyloid morphology and cytotoxicity.

Abstract
In sepsis, anticholinergic dysregulation may result in encephalopathy or delirium during severe illness, either as a result of central inflammation or because of exposure to medications with anticholinergic activity. In this retrospective study, we determined the magnitude of anticholinergic drug exposure in 75 children with severe sepsis. We found that exposure over the first 5 days was high-median (interquartile range) daily anticholinergic drug scale score 4 (2-5)-and associated with higher vasoactive scores and death. We conclude that anticholinergic drug exposure is significant in severe sepsis, which means it may be a modifiable factor that should be studied further.

Abstract
Lower urinary tract symptoms, including urgency, urgency incontinence, frequency, and nocturia, are highly prevalent in older adults and are associated with significant morbidity and impairment in quality of life. When conservative measures such as bladder training fail to improve symptoms, pharmacological management is recommended by national and international guidelines. Mirabegron, an agonist of the β3 adrenergic receptor, demonstrates similar efficacy to the anticholinergic drugs without the risk of anticholinergic effects, but experience and evidence in the very elderly population are limited. This narrative review examines the current evidence base for mirabegron in very elderly adults.

Abstract
BACKGROUND/OBJECTIVES Glycopyrronium tosylate (GT) cloth, 2.4% is a topical anticholinergic approved in the United States for primary axillary hyperhidrosis in patients ≥9 years. This post hoc analysis evaluated long-term response (efficacy and safety) in pediatric patients (≥9 to ≤16 years) to GT in the 44-week, open-label extension (NCT02553798) of two, phase 3, double-blind, vehicle-controlled, 4-week trials (NCT02530281, NCT02530294). METHODS In the double-blind trials, patients ≥9 years with primary axillary hyperhidrosis were randomized 2:1 to once-daily GT:vehicle. Those who completed the study could receive open-label GT for up to an additional 44 weeks. Safety assessments included treatment-emergent adverse events (TEAEs) and local skin reactions (LSRs). Descriptive efficacy assessments included gravimetrically measured sweat production, Hyperhidrosis Disease Severity Scale response (≥2-grade improvement), and Children's Dermatology Life Quality Index. RESULTS Of 43 pediatric patients completing either double-blind trial, 38 (88.4%) entered the open-label extension (age, years: 9 [n = 1], 12 [n = 2], 13 [n = 7], 14 and 15 [n = 9 each], 16 [n = 10]). The safety profile observed was similar to the double-blind trials. Most TEAEs (>95%) were mild/moderate, related to anticholinergic activity, and infrequently led to discontinuation (n = 1/38 [2.6%]). No pediatric patients experienced a serious TEAE. Most anticholinergic TEAEs did not require a dose modification and resolved within 7 days. Approximately, one-third of patients (n = 13/38 [34.2%]) had LSRs; most were mild/moderate in severity. Improvements in efficacy measures were maintained from the double-blind trials. CONCLUSIONS Long-term, once-daily GT for up to 48 weeks (4-week double-blind plus 44 week open label) provides a noninvasive, well-tolerated treatment option for pediatric patients with primary axillary hyperhidrosis.

Abstract
Rationale: Targeted lung denervation (TLD) is a bronchoscopic radiofrequency ablation therapy for chronic obstructive pulmonary disease (COPD), which durably disrupts parasympathetic pulmonary nerves to decrease airway resistance and mucus hypersecretion. Objectives: To determine the safety and impact of TLD on respiratory adverse events. Methods: We conducted a multicenter, randomized, sham bronchoscopy–controlled, double-blind trial in patients with symptomatic (modified Medical Research Council dyspnea scale score, ≥2; or COPD Assessment Test score, ≥10) COPD (FEV1, 30–60% predicted). The primary endpoint was the rate of respiratory adverse events between 3 and 6.5 months after randomization (defined as COPD exacerbation, tachypnea, wheezing, worsening bronchitis, worsening dyspnea, influenza, pneumonia, other respiratory infections, respiratory failure, or airway effects requiring therapeutic intervention). Blinding was maintained through 12.5 months. Measurements and Main Results: Eighty-two patients (50% female; mean ± SD: age, 63.7 ± 6.8 yr; FEV1, 41.6 ± 7.3% predicted; modified Medical Research Council dyspnea scale score, 2.2 ± 0.7; COPD Assessment Test score, 18.4 ± 6.1) were randomized 1:1. During the predefined 3- to 6.5-month window, patients in the TLD group experienced significantly fewer respiratory adverse events than those in the sham group (32% vs. 71%, P = 0.008; odds ratio, 0.19; 95% confidence interval, 0.0750–0.4923, P = 0.0006). Between 0 and 12.5 months, these findings were not different (83% vs. 90%; P = 0.52). The risk of COPD exacerbation requiring hospitalization in the 0- to 12.5-month window was significantly lower in the TLD group than in the sham group (hazard ratio, 0.35; 95% confidence interval, 0.13–0.99; P = 0.039). There was no statistical difference in the time to first moderate or severe COPD exacerbation, patient-reported symptoms, or other physiologic measures over the 12.5 months of follow-up. Conclusions: Patients with symptomatic COPD treated with TLD combined with optimal pharmacotherapy had fewer study-defined respiratory adverse events, including hospitalizations for COPD exacerbation. Clinical trial registered with www.clinicaltrials.gov (NCT02058459).

Abstract
BACKGROUND/OBJECTIVE In previous reports, the usage of anticholinergic medications has been associated with an increased risk of dementia with prolonged usage or with a high Anticholinergic Cognitive Burden (ACB). This study aimed to investigate the association between anticholinergic medications and the risk of dementia using data from Taiwan's National Health Research Database (NHIRD). METHODS A total of 790,240 patients, with 197,560 patients receiving anticholinergic medications and 592,680 control patients (1:3) matched for sex, age, and index-year, were enrolled from the two million Longitudinal Health Insurance Dataset, a subdataset of the NHIRD, between 2000 and 2015. The time-dependent Cox regression analysis was used to explore the hazard ratio (HR) with a 95% confidence interval for the association between anticholinergics and the risk of dementia during the 15-year follow-up. The behavioral and psychological symptoms of dementia (BPSD) were recognized by the usage of psychotropics. The ACB ranged from zero to three, divided as score <1, 1-1.9, 2-2.9, 3-4.9,and ≧5. The sensitivity analysis was done by excluding the diagnoses of dementia in the first 2 or 4 years after anticholinergic usage. RESULTS In the anticholinergic usage cohort, the HR was 1.043 (95% CI = 0.958-1.212, p = 0.139) without a significant difference. The sensitivity analysis revealed no association between the usage of anticholinergics and the risk of dementia. Anticholinergic usage was not associated with BPSD. Male sex, patients of ages of 60-64 and ≧80, usage of antiparkinsonian medications, a history of Parkinson's disease, epilepsy, urinary incontinence, depression, bipolar disorder, and psychotic disorder were independent risk factors of dementia. Increased HRs for dementia were associated with an ACB ≥ 5 and an anticholinergic usage period ≥ 1,460 days. CONCLUSION In this study, the usage of anticholinergics was not associated with the risk of dementia or BPSD in a 15-year follow-up study. However, patients with the male sex, patients with ages of 65-79 and ≧80, patients with some comorbidities, high ACB scores, and long anticholinergic treatment duration were associated with the risk of dementia.

Abstract
Death rattle commonly occurs at the end of life and is typically managed with anticholinergic agents. Myasthenia gravis is an autoimmune disorder characterized by fatigability of skeletal muscle, resulting from autoimmune destruction of acetylcholine receptors at the motor endplate. The condition is treated with acetylcholinesterase inhibitors, which potentiate the action of acetylcholine. Agents that antagonize acetylcholine activity (e.g., anticholinergic agents, such as glycopyrrolate) can, therefore, exacerbate myasthenia gravis. We discuss the case of a patient dying with myasthenia gravis that developed problematic "death rattle," and the successful use of glycopyrrolate in treating this symptom.
