Abstract
Numerous plants are traditionally grown in kitchen gardens and consumed by the general population. Incidents of accidental ingestion of harmful plants due to their striking resemblance with the edible ones are well-known. Cases: A family of three (a mother and her two children) unintentionally consumed leaves of small plants of Datura stramonium, instead of Solanum nigrum. They were admitted in intensive care unit with anticholinergic symptoms, treated symptomatically and discharged. On probing further, it is understood that both the plants look similar when young. However, it is easy to distinguish between them when the plants are fully grown. Conclusion: It is essential to educate the public regarding proper identification of locally available leafy vegetables that are fit for consumption. Also, clinicians should have a high index of suspicion in such cases of family poisoning even in the absence of a reliable history.

Steer AE, Ozcan J, Emeto TI. The role of anticholinergic medication in the prevention of bradycardia during laparoscopic gynaecological surgery. Aust N Z J Obstet Gynaecol 2019; 59:777-780. [PMID: 31657007 DOI: 10.1111/ajo.13079] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 08/17/2019] [Accepted: 09/11/2019] [Indexed: 11/28/2022]
Abstract
Bradycardia and cardiac arrest are recognised complications of laparoscopic gynaecological surgery. Anticholinergic agents are indicated in the treatment of perioperative bradyarrhythmia; however, their role in the prevention of bradycardia as a result of insufflation of the peritoneum is less well defined. This article systematically reviewed the literature with respect to the role of anticholinergic agents in the prevention of clinically significant bradyarrhythmia during laparoscopic gynaecological surgery. Eight studies were included for review following an extensive database search. This review highlights the paucity of evidence supporting the prophylactic use of anticholinergic agents in preventing clinically significant bradycardia in women undergoing laparoscopic gynaecological surgery.

Abstract
Introduction: Non-neurogenic urinary incontinence in children is a common condition that affects the quality of life for both patients and parents. Symptoms may occur in the daytime, nighttime, or both and may be the result of structural and functional anomalies. Evaluation and management of associated co-morbidities, such as constipation is critical to management. Behavioral therapy is a fist line therapy in most cases of non-neurogenic urinary incontinence and pharmacologic therapy a second-line therapy.Areas covered: In this review, the authors cover the pharmacologic agents, FDA approved and commonly used non-FDA approved, available for the treatment of four non-structural etiologies of non-neurogenic urinary incontinence in children. These include nocturnal enuresis, overactive bladder, giggle incontinence, and dysfunctional voiding.Expert opinion: Non-neurogenic causes of urinary incontinence in children represent a complicated medical condition that requires both pharmacologic and non-pharmacologic management. Limited FDA-approved therapies as well as suboptimal results with approved therapies due to a lack in the understanding of the underlying pathophysiology and patient selection may lead to the use of alternative non-FDA approved therapies.

Abstract
Background: Interleukin (IL)-26 is a neutrophil-mobilizing and bactericidal cytokine that is enhanced in human airways in vivo in response to endotoxin from Gram-negative bacteria. This cytokine is also enhanced in the airways during exacerbations of chronic obstructive pulmonary disease (COPD). Here, we investigated whether human primary lung fibroblasts (HLF) release IL-26 constitutively and in response to TLR4 stimulation by endotoxin and characterized the effects of bronchodilatory and anti-inflammatory drugs utilized in COPD. Methods: The HLF were stimulated with different concentrations of endotoxin. Cells were also treated with different concentrations of bronchodilatory and anti-inflammatory drugs, with and without endotoxin stimulation. Cytokine protein concentrations were quantified in the cell-free conditioned media [enzyme-linked immunosorbent assay (ELISA)], and the phosphorylation levels of intracellular signaling molecules were determined (phosphoELISA). Results: Whereas HLF displayed constitutive release of IL-26 into the conditioned medium, endotoxin markedly enhanced this release, as well as that of IL-6 and IL-8. This cytokine release was paralleled by increased phosphorylation of the intracellular signaling molecules NF-κB, c-Jun N-terminal kinase (JNK) 1-3, p38, and extracellular signal-regulated kinase (ERK) 1/2. The glucocorticoid hydrocortisone caused substantial inhibition of the endotoxin-induced release of IL-26, IL-6, and IL-8, an effect paralleled by a decrease of the phosphorylation of NF-κB, p38, and ERK1/2. The muscarinic receptor antagonist (MRA) tiotropium, but not aclidinium, caused minor inhibition of the endotoxin-induced release of IL-26 and IL-8, paralleled by a decreased phosphorylation of NF-κB. The β2-adrenoceptor agonist salbutamol caused modest inhibition of the endotoxin-induced release of IL-26 and IL-8, paralleled by a decreased phosphorylation of NF-κB, JNK1-3, and p38. Similar pharmacological effects were observed for the constitutive release of IL-26. Conclusions: The HLF constitute an abundant source of IL-26 that may contribute to local host defense against Gram-negative bacteria. Among the tested drugs, the glucocorticoid displayed the most powerful inhibitory effect, affecting the NF-κB, p38, and ERK1/2 signaling pathways. Whether or not this inhibition of IL-26 contributes to an increased risk for local infections in COPD requires further evaluation.

Abstract
Quetiapine in an atypical antipsychotic drug that is frequently used for delirium and behavioral and psychological symptoms in dementia. However, its potential anticholinergic effects, mediated primarily through its metabolite norquetiapine, could present as counterproductive adverse effects in these situations. There is little data published discussing this potential negative impact on quetiapine’s safety and tolerability, especially in the elderly. Here, we present what is, to our knowledge, the first published case report of delirium apparently induced by low-dose quetiapine, in a 95-year-old patient with no prior history of mental illness, and the potential role of its metabolite norquetiapine.

Abstract
OBJECTIVES To evaluate changes in the use of antipsychotics and medications with anticholinergic activity (MACs) during hospitalization in older adults with dementia and factors associated with antipsychotic prescriptions and increased anticholinergic burden (ACB). METHODS AND DESIGN This retrospective cohort study included all patients aged 65 years or older with a discharge diagnosis of dementia hospitalized at the university hospital of Udine, Italy, from 2012 to 2014. Medications dispensed within 3 months before and after hospitalization were identified in community-pharmacy dispensations while those prescribed at discharge were collected from Hospital Electronic Medical Records (EMR). ACB was assessed using the Anticholinergic Cognitive Burden score. RESULTS Among 1908 patients included, at discharge, 37.0% used one or more antipsychotic (9.4% before and 12.6% after hospitalization), 68.6% used one or more MAC (49.1% and 45.7%, respectively), and ACB of 38.4% of patients increased at discharge mainly because of a higher use of antipsychotics with anticholinergic activity (33% at discharge vs 12% before hospitalization). Prescription of antipsychotics at discharge was associated with prior treatment with antipsychotics (adjusted odds ratio [aOR] 4.85; 95%CI, 3.37-6.97), psychiatric conditions, (4.39; 3.47-5.54) and discharge from surgical department (2.17; 1.32-3.55). An increased ACB was associated with psychiatric conditions (1.91; 1.52-2.39), discharge from surgical (1.75; 1.09-2.80) or medical department (1.50; 1.04-2.17), and with cardiac insufficiency (1.41; 1.00-1.99). CONCLUSIONS ACB was higher at discharge, and antipsychotics were the main drivers of this increase. Clinicians treating older adults with dementia should be aware of the risks associated with antipsychotics and that some of these medications may increase the risk of anticholinergic effects.

Preliminary phytochemical analysis and evaluation of in vitro antioxidant, antiproliferative, antidiabetic, and anticholinergics effects of endemic Gypsophila taxa from Turkey. J Food Biochem 2019; 43:e12908. [PMID: 31353687 DOI: 10.1111/jfbc.12908] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Revised: 04/06/2019] [Accepted: 05/05/2019] [Indexed: 12/31/2022]
Abstract
The phenolic contents and antioxidant, anticancer, antidiabetic, and anticholinergic potentials of four endemic Gysophila taxa (G. pallida, G. arrosti, G. tuberculosa, and G. eriocalyx) were investigated. The HPLC analysis showed that methanol extracts of all the tested species were richer in phenolics than water extracts. 3,4-dihydroxybenzoic acid, p-hydroxybenzoic acid, vanillin, syringic acid, and p-coumaric acid were detected in all extracts. In parallel to the phenolic contents, methanol extracts displayed comparatively higher antioxidant activity than water extracts. Additionally, all extracts exhibited dose-dependent antiproliferative activity on the cancer cell lines with lower IC50 values changing from 0.170 to 1.805 mg/ml. Moreover, the extracts impressively inhibited the acetylcholinesterase (0.63-26.04), butyrylcholinesterase (3.66-10.73), and α-glycosidase (98.52-235.55) enzymes with very low IC50 (mg/ml) values. Together, the present results indicate that Gysophila taxa have various biological activities together with higher phenolic contents. Hence, these species hold good potential for use in the pharmaceutical industry. PRACTICAL APPLICATIONS: Gypsophila taxa having numerous biological activities have been used for different purpose in folk medicine as well as their use in the food industry. The obtained results of the current study indicated that the extracts of Gypsophila taxa are rich in phenolics and flavonoids with powerful antioxidant and antiproliferative activity against different type of cancer cell lines. In addition, the extracts obtained from these taxa showed notable antidiabetic and anticholinergics effects. Gypsophila taxa could be used as a natural material to develop anticancer, antidiabetic, and anticholinergic drugs.

Abstract
OBJECTIVES Older adults with dementia are particularly vulnerable to adverse outcomes resulting from anticholinergic use. We aimed to: (i) Examine the anticholinergic burden of patients with dementia attending a Psychiatry of Later Life (PLL) service (ii) Examine concomitant prescription of acetylcholinesterase inhibitors (AChEIs) and anticholinergics and (iii) Compare the Anticholinergic Cognitive Burden (ACB) scale with a recently published composite list of anticholinergics. METHODS Retrospective chart review of new referrals with a diagnosis of dementia (n = 66) seen by the PLL service, Tallaght University Hospital, Dublin, Ireland, over a consecutive period of 4 months. RESULTS The mean ACB score was 2.2 (range = 0-9, SD = 2.1). 37.9% (n = 25) had a clinically significant ACB score (>3) and 42.1% (n = 8) of those taking AChEIs had a clinically significant ACB score. A significantly greater number of medications with anticholinergic activity were identified using the composite list versus the traditional ACB scale (2.3 v.1.5, p = 0.001). CONCLUSIONS We demonstrated a significant anticholinergic burden amongst patients with dementia attending a specialist PLL service. There was no difference in anticholinergic burden between groups prescribed and not prescribed AChEIs, indicating that these medications are being prescribed without discontinuation of potentially inappropriate medications with anticholinergic activity. The true anticholinergic burden experienced by patients may be underestimated by the use of the ACB score alone, although the clinical significance of this finding is unclear. Calculation of true clinical anticholinergic burden load and its translation to a specific rating scale remains a challenge.

Abstract
Background: Antimuscarinic delirium is associated with significant morbidity, and its management requires substantial resource allocation, including intubation, restraint, and intensive care unit (ICU) placement. There is controversy over the management of these patients. Physostigmine can rapidly reverse antimuscarinic delirium but has been associated with adverse effects. Objective: This study aims to assess the effect of physostigmine use on resource allocation and adverse events. Methods: This is a retrospective chart review of patients with an antimuscarinic toxidrome at a single hospital approved by the local institutional review board. A blinded abstractor recorded data from patient charts. Whether the patient was given physostigmine, intubated, restrained, or admitting to critical care was recorded. We recorded instances of seizure, vomiting, or bradycardia. The primary aim was to compare frequency of intubation as a function of physostigmine administration. Results: A total of 141 patients were identified. We found no difference between the groups in age, gender, or initial heart rate; 65 (46%) were given physostigmine, 45 (32%) were admitted to the ICU, and 29 (20%) were intubated. Patients who received physostigmine in the first 24 hours were less likely to be intubated and less likely to be admitted to an ICU. The instance of bradycardia (n = 16), vomiting (n = 27), and seizures (n = 7) was limited, and there were no significant differences between the groups. There were no associations noted between physostigmine administration and adverse effects. Conclusion and Relevance: This study demonstrated that physostigmine use is associated with decreased resource utilization (including intubation and ICU placement) without increasing rates of bradycardia, vomiting, or seizures.

Abstract
Allergic rhinitis (AR) is a chronic upper respiratory disease estimated to affect between 10 and 40% of the worldwide population. The mechanisms underlying AR are highly complex and involve multiple immune cells, mediators, and cytokines. As such, the development of a single drug to treat allergic inflammation and/or symptoms is confounded by the complexity of the disease pathophysiology. Complete avoidance of allergens that trigger AR symptoms is not possible and without a cure, the available therapeutic options are typically focused on achieving symptomatic relief. Topical therapies offer many advantages over oral therapies, such as delivering greater concentrations of drugs to the receptor sites at the source of the allergic inflammation and the reduced risk of systemic side effects. This review describes the complex pathophysiology of AR and identifies the mechanism(s) of action of topical treatments including antihistamines, steroids, anticholinergics, decongestants and chromones in relation to AR pathophysiology. Following the literature review a discussion on the future therapeutic strategies for AR treatment is provided.

Abstract
BACKGROUND Respiratory distress protocols (RDPs) are protocolized prescriptions comprised of 3 medications (a benzodiazepine, an opioid, and an anticholinergic) administered simultaneously as an emergency treatment for respiratory distress in palliative care patients in the province of Quebec, Canada. However, data on appropriate use that justifies the combination of all 3 components is scarce and based on individual pharmacodynamic properties along with expert consensus. OBJECTIVES Our study aimed to evaluate the conformity and the effectiveness of RDPs prescribed and administered to hospitalized adult patients. METHODS This was a prospective and descriptive study conducted in a single center. Prescription and administration conformity were assessed based on predefined appropriateness criteria. RESULTS A total of 467 adult patients were prescribed a RDP, 175 administrations were documented, and 78 patients received at least 1 RDP. Prescription conformity was assessed on 1473 separate occasions over the trial period. Overall prescription conformity was found to be 37% (95% confidence interval [CI]: 33.6-40.4), and administration conformity was 37.7% (95% CI: 26.2-50.7). Low administration conformity was primarily explained by incorrect indications for RDP use. Seemingly important determinants of higher conformity were prescriber's speciality in palliative care, use of preprinted orders, pharmacist involvement, and hospitalization in the palliative care unit. CONCLUSION This study highlights important gaps in the use of RDPs in our institution. Health-care provider training appears necessary in order to ensure adequate conformity and allow for further evaluation of RDP effectiveness.

Abstract
Despite major advances in therapeutic interventions and the availability of detailed treatment guidelines, a high proportion of patients with symptomatic asthma remain uncontrolled. Asthma management is largely guided by the Global Initiative for Asthma (GINA) strategy and is based on a backbone of inhaled corticosteroid (ICS) therapy with the use of additional therapies to achieve disease control. Inhaled long-acting bronchodilators alone and in combination are the preferred add-on treatment options. Although long-acting muscarinic antagonists (LAMAs) are a relatively recent addition to disease management recommendations for asthma, tiotropium has been extensively studied in a large clinical trial program. In Europe and the United States, tiotropium is approved for patients aged ≥6 years and uncontrolled on medium- to high-dose ICS/long-acting β2-agonists at GINA Steps 4 and 5 with a history of exacerbations. Evidence supports the efficacy of tiotropium Respimat® in adults in terms of lung function and asthma control, with a safety profile comparable with that of placebo across a range of asthma severities. Similarly, clinical trials in patients aged 1-17 years have shown improvements in lung function and trends toward improved asthma control. Furthermore, its efficacy makes tiotropium relatively easy to incorporate into routine clinical practice, irrespective of allergic status and without the need for patient phenotyping. Tiotropium is a cost-effective treatment that may offer an important alternative to other, more expensive add-on therapies. This review discusses the potential future position of LAMAs in clinical practice by considering the continuously evolving evidence. Prominence is given to tiotropium, the only LAMA supported by a structured clinical trial program in asthma to date, while also considering other recommended treatment options for patients with uncontrolled asthma. The importance of effective patient/caregiver-clinician communication and shared decision-making in enhancing treatment adherence is also highlighted.

Abstract
Asthma is the most common chronic airway disease in children, with more than half the reported cases of persistent asthma starting in children below the age of 3 years. Asthma diagnosis in preschool children has proven to be challenging due to the heterogeneity of the disease, the continuing development of the immune system in such a young population, and lack of diagnostic options such as lung function measurement. Early diagnosis and treatment of asthmatic symptoms will improve patients' quality of life and help reduce disease morbidity. However, validated treatment options are scarce due to paucity of data and lack of conclusive studies in such a young patient population. Adjusting study design and endpoints to capture more reliable data with minimal risk of harm to patients is necessary. This thematic series review outlines the current position on preschool asthma, consolidates the current understanding of risk factors and diagnostic hurdles, and emphasizes the importance of early detection and management to help improve patients' quality of life, both present and future. Particular focus was given to anticholinergics and their emerging role in the treatment and control of asthma in pediatric patients.

Abstract
The burden of uncontrolled asthma in children and adolescents is high. Treatment options for pediatric patients (aged under 18 years) with asthma are largely influenced by the Global Initiative for Asthma recommendations. Algorithms for adolescents (12-18 years) and adults are identical, but recommendations for children aged under 6 years and 6-11 years differ. Although the goals of treatment for pediatric patients with asthma are similar to those for adults, relatively few new therapies have been approved for this patient population within the last decade. Designing clinical trials involving children presents several challenges, notably that children are often less able to perform lung function tests, and traditional endpoints used in clinical trials with adults, such as forced expiratory volume in 1 second, asthma exacerbations and questionnaires, have limitations associated with their use in children. There are also ethical considerations related to the performance of longer placebo-controlled exacerbation trials. This review considers additional clinical endpoints to those traditionally reported, including forced expiratory flow at 25%-75% of forced vital capacity, which may help shed light on which treatments are most effective for use in pediatric patients with asthma. The pros and cons of specific and potentially clinically relevant endpoints are considered, along with device considerations and patient preferences that may enhance adherence and quality of life. Recent advances in the management of children and adolescents, including the US Food and Drug Administration and European Medicines Agency approval of tiotropium in patients with asthma aged 6 years and over, are also discussed.

Abstract
Hyperhidrosis is a condition characterized by excessive sweat production beyond which is physiologically necessary for thermal regulation. Affecting over 4.8% of the United States population, studies have shown that severe primary hyperhidrosis interferes with daily activities and can be considered intolerable, negatively impacting a patient’s quality of life. Glycopyrronium tosylate is a topical anticholinergic agent that reduces sweat production by blocking the activation of acetylcholine receptors in peripheral sweat glands. In clinical trials, topical glycopyrronium tosylate, a pre-moistened cloth containing 2.4% glycopyrronium solution, was shown to be an effective, safe and non-invasive treatment for patients suffering from primary hyperhidrosis. This review examines the clinical trials of topical glycopyrronium tosylate and its role in primary hyperhidrosis. Glycopyrronium tosylate was recently US FDA-approved (as of June 2018) to manage patients with primary axillary hyperhidrosis.

Abstract
Background: Hypertension is prevalent in older adults. Hypertension has also been associated with an increased risk of cognitive decline. However, evidence relating to the impact of antihypertensive use is mixed. Calcium-channel blockers (CCB) have been suggested as the most beneficial class of antihypertensive for protection of cognition in older adults, however, to date, there have been no cohort studies designed to examine this. Methods: Community-dwelling treated hypertensive adults aged 80 and over were recruited from general practice sites and followed for 1 year. Cognitive function was assessed at baseline and 12 months using the modified Mini-Mental State Exam (3MS). Regression was used to examine the association between 12-month exposure to antihypertensive class and change in cognitive function. Results: A total of 292 participants completed the study. Mean change in 3MS score was a rise of 0.53 [standard deviation (SD) 4.7] 3MS points in those taking CCBs (n = 135) compared with a drop of 0.09 (SD 5.1) in those without (n = 157) p = 0.28. There was no relationship between CCBs or between any antihypertensive class and change in cognitive function over 1 year. Additional analyses using a clinically meaningful fall of 5 or more 3MS points showed similar results. Conclusion: In a hypertensive community-dwelling older adult population treated with antihypertensives, there was no evidence that CCBs were protective of cognitive function over a 12-month exposure. If a protective effect is present, it may be small or require a longer treatment period. Larger longer studies are required for confirmation.

Abstract
OBJECTIVE Benzodiazepines and anticholinergics are risk factors for delirium in the intensive care unit (ICU). We tested the impact of a deprescribing intervention on short-term delirium outcomes. DESIGN Multisite randomized clinical trial. SETTING ICUs of three large hospitals. PARTICIPANTS Two hundred adults aged 18 years or older and admitted to an ICU with delirium, according to the Richmond Agitation-Sedation Scale and the Confusion Assessment Method for the ICU (CAM-ICU). Participants had a contraindication to haloperidol (seizure disorder or prolonged QT interval) or preference against haloperidol as a treatment for delirium, and were excluded for serious mental illness, stroke, pregnancy, or alcohol withdrawal. Participants were randomized to a deprescribing intervention or usual care. The intervention included electronic alerts combined with pharmacist support to deprescribe anticholinergics and benzodiazepines. MEASUREMENTS Primary outcomes were delirium duration measured by the CAM-ICU and severity measured by the Delirium Rating Scale Revised-98 (DRS-R-98) and the CAM-ICU-7; secondary outcomes included adverse events and mortality. RESULTS Participants had a mean age of 61.8 (SD = 14.3) years, 59% were female, and 52% were African American, with no significant differences in baseline characteristics between groups. No differences between groups were identified in the number exposed to anticholinergics (P = .219) or benzodiazepines (P = .566), the median total anticholinergic score (P = .282), or the median total benzodiazepine dose in lorazepam equivalents (P = .501). Neither median delirium/coma-free days (P = .361) nor median change in delirium severity scores (P = .582 for DRS-R-98; P = .333 for CAM-ICU-7) were different between groups. No differences in adverse events or mortality were identified. CONCLUSIONS When added to state-of-the-art clinical services, this deprescribing intervention had no impact on medication use in ICU participants. Given the age of the population, results of clinical outcomes may not be easily extrapolated to older adults. Nonetheless, improved approaches for deprescribing or preventing anticholinergics and benzodiazepines should be developed to determine the impact on delirium outcomes.

Abstract
Radiation therapy requires repeated anesthetic administration to patients who often have multiple comorbidities contributing to an increased rate of anesthetic complications such as pneumonia. This is a retrospective observational study in which data were collected from 146 medical records of dogs receiving repeat anesthesia for radiation treatment from prior to management changes and compared to data from 149 cases treated after completion of management changes. The objective was to determine if changes in case management protocol that were put in place decreased the risk of pneumonia development among these patients. Management changes that were made included the following: decrease in anticholinergic and pure-mu opioid use, change in positioning during intubation and recovery, prophylactic treatment of nausea, timing of cuff inflation and deflation, and aseptic handling of intubation equipment. There was a significant association between diagnosis of pneumonia and the following: pre- vs. post-changes to protocol, presence of a neurologic tumor, presence of respiratory disease, presence of megaesophagus, and number of radiation fractions completed. Diagnosis of pneumonia did not vary significantly by age group, body weight category, or sex. In a multivariable logistic regression model that controlled for the effects of the three concurrent diseases and fractions completed, the odds of being diagnosed with pneumonia were approximately 10 times greater among dogs anesthetized prior to management changes (odds ratio = 9.9, 95% CI = 2.0-48.7, P = 0.005).

Abstract
INTRODUCTION Cognitive impairment is a core feature and shows the highest impact on functional outcome in patients with schizophrenia. There have been no previous studies investigating the role of the pharmacist in a multidisciplinary team on cognitive outcomes in patients with schizophrenia. PURPOSE We evaluated the impact of pharmacist intervention on cognitive outcomes in patients with schizophrenia by focusing on anticholinergic discontinuation. PATIENTS AND METHODS A prospective, open-label, randomized, controlled study was conducted. Patients with schizophrenia were randomly assigned to either the pharmacist intervention or usual care groups. In the pharmacist intervention group, the pharmacist identified drug-related problems (DRPs) and provided a pharmacotherapy suggestion, while there was no intervention in the usual care group. The primary outcome was mean change from baseline of executive function by using Wisconsin Card Sorting Test (WCST) perseverative errors within the pharmacist intervention group at week 12. RESULTS A total of 30 patients completed the study (13 in the pharmacist intervention group and 17 in the usual care group). WCST perseverative errors at the end of the study within the pharmacist intervention group improved significantly from baseline (P=0.003). DRPs at week 12 were reduced by 85.19% and 9.76% in the pharmacist intervention and usual care groups, respectively. The most common intervention was the discontinuation of anticholinergics in patients without extrapyramidal side effects. CONCLUSION Added-on pharmacist intervention in a multidisciplinary team could help to improve cognitive functions in patients with schizophrenia by reducing DRPs and optimizing the drug therapy regimen, especially for anticholinergic discontinuation.

Abstract
BACKGROUND Previous studies have shown associations between the use of anticholinergics (AC) and cognitive performance in the elderly, considering AC as a homogeneous set of drugs. The present study aims to assess the relationship between exposure to AC drugs and cognitive performance in middle-aged adults according to AC potency and drug class. METHODS Our cross-sectional study used baseline data of 34 267 participants aged 45-70 from the Consultants des centres d'examen de santé de la sécurité sociale (CONSTANCES) cohort. The cumulative exposure to AC was measured using national reimbursement databases over the 3-year period preceding assessment of cognitive performance. Eight classes of AC drugs were differentiated. Episodic verbal memory, language abilities and executive functions were evaluated by validated neuropsychological tests. Analyses were controlled on lifestyle and health status variables. RESULTS This study showed a negative association between overall cumulative AC exposure and cognitive performances after adjustment. The use of drugs with possible AC effect according to the Anticholinergic Cognitive Burden scale (ACB-1 score) was only associated with executive functions. Analyses of AC exposure across drug classes showed a negative association between the use of AC antipsychotics and all cognitive functions assessed. Heterogeneous associations were found for the use of AC anxiolytics, AC opioids and AC drugs targeting the gastrointestinal tract or metabolism. We did not find significant associations between the use of antihistamines, antidepressants, cardiovascular system or other AC medications and cognitive function. CONCLUSION Association between AC drugs and cognitive performance was highly heterogeneous across drug classes; this heterogeneity will have to be considered by future studies.

Abstract
OBJECTIVES It is important to describe and understand the prevalence and risk factors for the syndrome of delirium in critical illness. Since anticholinergic medication may contribute to the development of delirium in the PICU, we have sought to quantify anticholinergic medication exposure in patients with prolonged admission. We have used Anticholinergic Drug Scale scores to quantify the magnitude or extent of this burden. DESIGN Retrospective cohort study, January 2011 to December 2015. SETTING Single academic medical center PICU. PATIENTS Children under 18 years old with a PICU admission of 15 days or longer, requiring mechanical ventilation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Daily Anticholinergic Drug Scale scores for the first 15 days of admission, in each of 88 subjects (total of 1,320 PICU days), were collected and assessed in relation to demographic data, severity of illness, and medication use. Median (interquartile range) of daily Anticholinergic Drug Scale score was 5 (interquartile range, 3-7). Anticholinergic Drug Scale score was not associated with age, sex, medical history, presenting Severity of Illness score, PICU length of stay, ventilator hours, or hospital mortality. Medications most frequently associated with high Anticholinergic Drug Scale score were low potency anticholinergic drugs such as morphine, midazolam, vancomycin, steroids, and furosemide, with the exception of ranitidine (Anticholinergic Drug Scale score 2). Patients receiving high doses of midazolam infusion had significantly higher Anticholinergic Drug Scale scores compared with those receiving lower or no midazolam dosing. CONCLUSIONS A high number of medications with anticholinergic effects are administered to PICU patients receiving prolonged mechanical ventilation. These exposures are much higher than those reported in adult intensive care patients. Since anticholinergic drug exposure is associated with delirium, further study of this exposure in PICU patients is needed.

Abstract
Long-acting muscarinic antagonists (LAMAs), along with long-acting β2-agonists (LABAs), are the mainstay for treatment of patients with COPD. Glycopyrrolate, or glycopyrronium bromide, like other LAMAs, inhibits parasympathetic nerve impulses by selectively blocking the binding of acetylcholine to muscarinic receptors. Glycopyrrolate is unusual in that it preferentially binds to M3 over M2 muscarinic receptors, thereby specifically targeting the primary muscarinic receptor responsible for bronchoconstriction occurring in COPD. Inhaled glycopyrrolate is slowly absorbed from the lungs and rapidly eliminated from the bloodstream, most likely by renal excretion in its unmetabolized form, limiting the potential for systemic adverse events. Inhaled glycopyrrolate is a fast-acting, efficacious treatment option for patients with moderate-severe COPD. It improves lung function, reduces the risk of exacerbations, and alleviates the symptoms of breathlessness, which in turn may explain the improvement seen in patients' quality of life. Inhaled formulations containing glycopyrrolate are well tolerated, and despite being an anticholinergic, few cardiovascular-related events have been reported. Inhaled glycopyrrolate is thus of value as both monotherapy and in combination with other classes of medication for maintenance treatment of COPD. This review covers the mechanism of action of inhaled glycopyrrolate, including its pharmacokinetic, pharmacodynamic, and safety profiles, and effects on mucus secretion. It also discusses the use of inhaled glycopyrrolate in the treatment of COPD, as monotherapy and in fixed-dose combinations with LABAs and inhaled corticosteroid-LABAs, including a triple therapy recently approved in Europe.

Abstract
STUDY OBJECTIVE To determine the influence of anticholinergic medications on transitions in cognitive diagnosis of older adults in primary care. DESIGN This observational cohort study was conducted over a mean follow-up of 3.2 years. Anticholinergic exposure was defined by pharmacy dispensing and claims records. Cognitive diagnosis was performed by an expert panel at baseline and annually up to 4 years. DATA SOURCE Medication exposure and other clinical data were extracted from the Indiana Network for Patient Care (INPC). The cognitive diagnosis was derived from a cognitive screening and diagnosis study. PARTICIPANTS A total of 350 adults 65 years and older without dementia and receiving primary care in a safety net health care system. MEASUREMENT AND MAIN RESULTS Cognitive diagnosis followed a two-phase screening and consensus-based neuropsychiatric examination to determine a baseline diagnosis as normal cognition, mild cognitive impairment (MCI), or dementia, with a follow-up neuropsychiatric examination and consensus-based diagnosis repeated annually. The Anticholinergic Cognitive Burden scale was used to identify anticholinergics dispensed up to 10 years before enrollment and annually throughout the study. A total standard daily dose of anticholinergics was calculated by using pharmacy dispensing data from the INPC. Among 350 participants, a total of 978 diagnostic assessments were completed over a mean follow-up of 3.2 years. Compared with stable cognition, increasing use of strong anticholinergics calculated by total standard daily dose increased the odds of transition from normal cognition to MCI (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.01-1.31, p = 0.0342). Compared with stable MCI, strong anticholinergics did not influence the reversion of MCI to normal cognition (OR 0.95, 95% CI 0.86-1.05, p = 0.3266). CONCLUSION De-prescribing interventions in older adults with normal cognition should test anticholinergics as potentially modifiable risk factors for cognitive impairment.
