Abstract
Overactive bladder syndrome (OAB) is defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency incontinence, in the absence of urinary tract infection or other obvious pathology. The mainstay of treatment of OAB is anticholinergic/antimuscarinic medication. These drugs block muscarinic receptors throughout the body, not only the bladder, including in the brain, which may lead to cognitive side effects. Anticholinergic load or burden is the cumulative effect of taking drugs that are capable of producing anticholinergic adverse effects. The elderly are more susceptible to these effects, especially as there is increased permeability of the blood brain barrier. The anticholinergic drugs for OAB are able to enter the central nervous system and lead to central side effects. There is increasing evidence that a high anticholinergic load is linked to the development of cognitive impairment and even dementia. Some studies have found an increased risk of mortality. In view of this, care is needed when treating OAB in the elderly. Trospium chloride is a quaternary amine anticholinergic, which has a molecular structure, which theoretically means it is less likely to cross the blood brain barrier and exert central side effects. Alternatively, mirabegron can be used, which is a beta-3 adrenoceptor agonist, which does not add to the anticholinergic load or exert central nervous system side effects. Conservative therapy can be used as an alternative to pharmacological treatment in the form of behavioral modification, fluid management and bladder retraining. Neuromodulation or the use of botox can also be alternatives, but success may be less in the older adult and will require increased hospital attendances.

Abstract
Background: This document provides clinical recommendations for the pharmacologic treatment of chronic obstructive pulmonary disease (COPD). It represents a collaborative effort on the part of a panel of expert COPD clinicians and researchers along with a team of methodologists under the guidance of the American Thoracic Society. Methods: Comprehensive evidence syntheses were performed on all relevant studies that addressed the clinical questions and critical patient-centered outcomes agreed upon by the panel of experts. The evidence was appraised, rated, and graded, and recommendations were formulated using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Results: After weighing the quality of evidence and balancing the desirable and undesirable effects, the guideline panel made the following recommendations: 1) a strong recommendation for the use of long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) combination therapy over LABA or LAMA monotherapy in patients with COPD and dyspnea or exercise intolerance; 2) a conditional recommendation for the use of triple therapy with inhaled corticosteroids (ICS)/LABA/LAMA over dual therapy with LABA/LAMA in patients with COPD and dyspnea or exercise intolerance who have experienced one or more exacerbations in the past year; 3) a conditional recommendation for ICS withdrawal for patients with COPD receiving triple therapy (ICS/LABA/LAMA) if the patient has had no exacerbations in the past year; 4) no recommendation for or against ICS as an additive therapy to long-acting bronchodilators in patients with COPD and blood eosinophilia, except for those patients with a history of one or more exacerbations in the past year requiring antibiotics or oral steroids or hospitalization, for whom ICS is conditionally recommended as an additive therapy; 5) a conditional recommendation against the use of maintenance oral corticosteroids in patients with COPD and a history of severe and frequent exacerbations; and 6) a conditional recommendation for opioid-based therapy in patients with COPD who experience advanced refractory dyspnea despite otherwise optimal therapy. Conclusions: The task force made recommendations regarding the pharmacologic treatment of COPD based on currently available evidence. Additional research in populations that are underrepresented in clinical trials is needed, including studies in patients with COPD 80 years of age and older, those with multiple chronic health conditions, and those with a codiagnosis of COPD and asthma.

Abstract
Introduction Although antimuscarinics form the first-line therapy in overactive bladder (OAB), little is known regarding antimuscarinic discontinuation among OAB patients in nursing homes. This study examined treatment patterns and predictors of antimuscarinic discontinuation among long-term nursing home (LTNH) residents with OAB. Methods The study cohort included LTNH residents (defined as residents staying ≥ 101 consecutive days) from the Minimum Data Set linked 2013–2015 Medicare claims data. Patients with OAB were defined by OAB-related claims and medication codes. Treatment patterns and discontinuation (medication gap ≥ 30 days) were characterized by examining OAB-specific antimuscarinics prescribed during LTNH stays. The Andersen Behavioral Model was used to identify predisposing, enabling and need factors that predict discontinuation. Kaplan-Meier curves and multivariable Cox proportional hazards regression model were used to assess the unadjusted and adjusted times to discontinuation, respectively, among different antimuscarinics. Results The mean age of the study cohort (n = 11,012) was 81.6 years (± 8.5), 74.6% were female, and 89.8% were non-Hispanic White. The mean duration of nursing home stay was 530.1 (± 268.4) days. The most commonly prescribed OAB-specific antimuscarinic was oxybutynin (69.8%). Overall, 66.5% of the study cohort discontinued the index antimuscarinic. Multivariable Cox PH regression analysis revealed that compared to LTNH residents who initiated treatment with oxybutynin, treatment discontinuation was lower with solifenacin or fesoterodin and discontinuation was more frequent when treatment was initiated with tolterodine, darifenacin or trospium compared with oxybutynin. In addition, several need factors (comorbidities, medication use and anticholinergic burden, etc.) were associated with antimuscarinic discontinuation. Conclusion About two-thirds of LTNH residents with OAB discontinued their index antimuscarinic during their nursing home stay. There was significant variation in discontinuation based on the index antimuscarinic agent with lowest risk of discontiuation with solifenacin and fesoterodin. Concerted efforts to optimize antimuscarinic use are needed to improve the management of OAB in nursing homes.

Abstract
INTRODUCTION Multiple Sclerosis (MS) manifests with a plethora of signs and symptoms affecting brain structures and spinal pathways. The multitude of lesions in MS patients makes difficult to establish the relative role of each of them to lower urinary tract symptoms (LUTS). Generally, the subcortical white-matter lesions result in detrusor overactivity, whilst lesions of the spinal cord result in the combined occurrence of detrusor overactivity and detrusor-sphincter dyssynergia (DSD). It has been estimated that 80-90% of patients with MS will suffer from some form of LUTS over the course of the disease. Among LUTS, the most reported is detrusor overactivity which includes urinary urgency, frequent urination, nocturia, and urge urinary incontinence. AREAS COVERED The authors review the management of lower urinary tract symptoms in MS patients providing their expert opinions on the subject matter. EXPERT OPINION LUTS affect the quality of life substantially and are associated with a significantly increased mortality. The adequate management is an important challenge for both patients and caregivers with a multidisciplinary approach likely necessary.

Abstract
OBJECTIVE To evaluate whether the lower dropout rate of the treatment of overactive bladde r(OAB) with mirabegron could generate cost savings to the National Health System (NHS) and lead to quality-adjusted life years (QALYs) gains, compared to the most commonly prescribed antimuscarinics (AM) in Spain (tolterodine, fesoterodine, oxybutynin, solifenacin). METHODS A probabilistic model (second order Monte Carlo simulation) in a hypothetical cohort of 1,000 patients with OAB and a time horizon of 1 year was carried out. Discontinuation and persistence rates for both mirabegron and AM were obtained from a Spanish observational study in 1798 patients. Unit costs (€ 2018) and utility loss associated with treatment discontinuation were obtained from Spanish public prices and literature, respectively. RESULTS Persistence rates in patients treated with mirabegron were twice as high compared to AM, leading to a QALY gain of 0.0151 ± 0.0007 per year. Treatment with mirabegron could generate savings of 80.74 ±4.61 € per patient per year compared to AM, assuming 100% probability of saving. The hypothetical substitution of AM treatment for mirabegron could potentially generate savings of 6.6 million euros (95% CI 3.9-10.1 million euros) to the NHS and 1,238 QALYs gains (CI95%731; 1,885 QALYs) within a period of 1 year. CONCLUSIONS The probabilistic model presented showed a greater persistence in patients treated with mirabegron compared to AM, leading to a positive impactin patients quality of life, as well cost savings to the NHS in Spain.

Abstract
RATIONALE Voiding difficulty is more common in males, although it is not uncommon in females. Female voiding difficulty can be caused by iatrogenic, anatomic, and neurogenic factors, and specifically urethra stricture, impaired detrusor contractility, primary bladder neck obstruction, and detrusor-external sphincter dyssynergia. Labial adhesion is a rare cause of female voiding difficulty.The incidence of labial fusion has been reported to be 0.6% to 1.4% in children; however, the incidence in the elderly has yet to be fully elucidated. PATIENT CONCERNS We present the case of a postmenopausal and sexually inactive 76-year-old female patient who had nearly total vaginal and urethral occlusion due to labial adhesion. She had no underlying diseases and came to our clinic with a 10-month history of voiding difficulty, postmicturition dribbling, and involuntary urinary leakage when getting up. DIAGNOSIS A genital examination revealed nearly total fusion of the labia minor with only a 3-mm pinhole opening at the posterior end. INTERVENTIONS Treatment included surgical separation, the local application of estrogen cream, and self-dilatation. She also received an antimuscarinic agent to treat overactive bladder secondary to bladder outlet obstruction which was caused by labial adhesion. OUTCOMES No surgical complications occurred. Moreover, no labial adhesion or voiding dysfunction was found immediately after the surgery or after 6 months of follow-up. LESSONS SUBSECTIONS Genital examinations are a basic but very important noninvasive skill for physicians. This case report highlights that genital examinations should be a priority for patients with gynecological or urological symptoms.

Abstract
Purpose The clinical manifestation of COPD can differ by gender, with women experiencing worse lung function and health-related quality of life than men. Additionally, women tend to report more symptoms given the same disease severity. Accordingly, the impact of gender on efficacy and safety in patients with moderate-to-very-severe COPD was examined following 12 weeks of nebulized glycopyrrolate (GLY) 25 µg twice daily (BID) or placebo. Patients and Methods GLY and placebo pooled data from the replicate 12-week GOLDEN 3 and 4 studies (n=861) were grouped by gender. Endpoints reported were change from baseline in trough forced expiratory volume in 1 second (FEV1), St George's Respiratory Questionnaire (SGRQ) and EXAcerbations of COPD Tool-Respiratory Symptoms (EXACT-RS) total scores. Safety was evaluated by reviewing the incidence of adverse events (AEs) and serious AEs. Results Men (placebo: 54.7%; GLY: 56.1%) were generally older with a greater proportion of high cardiovascular risk and use of background long-acting β2-agonists or inhaled corticosteroids. GLY treatment resulted in significant, clinically important improvements in trough FEV1, regardless of gender. Patients treated with GLY reported significant improvements in SGRQ total score, irrespective of gender; however, the improvement was numerically higher in women. Although EXACT-RS improved in both genders, only women experienced a significant improvement. Overall, GLY was well tolerated with a numerically lower incidence of AEs in men than women. Conclusion Treatment with nebulized GLY resulted in lung function, SGRQ total score, and EXACT-RS total score improvements regardless of gender. However, only EXACT-RS showed significantly greater improvements in women compared with men. Treatment with GLY was generally well tolerated across genders. These data support the efficacy and safety of GLY 25 µg BID in patients with moderate-to-very-severe COPD, independent of gender. Gender similarities in airflow improvement and differences in symptom-reporting augment the evidence supporting the consideration of individualized treatment plans for COPD patients.

Abstract
Suicidal ingestion of organophosphorus (OP) or carbamate (CM) compounds challenges health care systems worldwide, particularly in Southeast Asia. The diagnosis and treatment of OP or CM poisoning is traditionally based on the clinical appearance of the typical cholinergic toxidrome, e.g. miosis, salivation and bradycardia. Yet, clinical signs might be inconclusive or even misleading. A current case report highlights the importance of enzymatic assays to provide rapid information and support clinicians in diagnosis and rational clinical decision making. Furthermore, the differentiation between OP and CM poisoning seems important, as an oxime therapy will most probably not provide benefit in CM poisoning, but—as every pharmaceutical product—it might result in adverse effects. The early identification of the causing agent and the amount taken up in the body are helpful in planning of the therapeutic regimen including experimental strategies, e.g. the use of human blood products to facilitate scavenging of the toxic agent. Furthermore, the analysis of biotransformation products and antidote levels provides additional insights into the pathophysiology of OP or CM poisoning. In conclusion, cholinesterase activities and modern analytical methods help to provide a more effective treatment and a thorough understanding of individual cases of OP or CM poisoning.

Abstract
BACKGROUND Urgency urinary incontinence afflicts many adults, and most commonly affects women. Medications, a standard treatment, may be poorly tolerated, with poor adherence. This warrants investigation of alternative interventions. Mind-body therapies such as hypnotherapy may offer additional treatment options for individuals with urgency urinary incontinence. OBJECTIVE To evaluate hypnotherapy's efficacy compared to medications in treating women with urgency urinary incontinence. MATERIALS AND METHODS This investigator-masked, noninferiority trial compared hypnotherapy to medications at an academic center in the southwestern United States, and randomized women with non-neurogenic urgency urinary incontinence to weekly hypnotherapy sessions for 2 months (and continued self-hypnosis thereafter) or to medication and weekly counseling for 2 months (and medication alone thereafter). The primary outcome was the between-group comparison of percent change in urgency incontinence on a 3-day bladder diary at 2 months. Important secondary outcomes were between-group comparisons of percent change in urgency incontinence at 6 and 12 months. Outcomes were analyzed based on noninferiority margins of 5% for between group differences (P < 0.025) (that is, for between group difference in percentage change in urgency incontinence, if the lower bound of the 95% confidence interval was greater than -5%, noninferiority would be proved). RESULTS A total of 152 women were randomized to treatment between April 2013 and October 2016. Of these women, 142 (70 hypnotherapy, 72 medications) had 3-day diary information at 2 months and were included in the primary outcome analysis. Secondary outcomes were analyzed for women with diary data at the 6-month and then 12-month time points (138 women [67 hypnotherapy, 71 medications] at 6 months, 140 women [69 hypnotherapy, 71 medications] at 12 months. There were no differences between groups' urgency incontinence episodes at baseline: median (quartile 1, quartile 3) for hypnotherapy was 8 (4, 14) and medication was 7 (4, 11) (P = .165). For the primary outcome, although both interventions showed improvement, hypnotherapy did not prove noninferior to medication at 2 months. Hypnotherapy's median percent improvement was 73.0% (95% confidence interval, 60.0-88˖9%), whereas medication's improvement was 88.6% (95% confidence interval, 78.6-100.0%). The median difference in percent change between groups was 0% (95% confidence interval, -16.7% to 0.0%); because the lower margin of the confidence interval did not meet the predetermined noninferiority margin of greater than -5%, hypnotherapy did not prove noninferior to medication. In contrast, hypnotherapy was noninferior to medication for the secondary outcomes at 6 months (hypnotherapy, 85.7% improvement, 95% confidence interval, 75.0-100%; medications, 83.3% improvement, 95% confidence interval, 64.7-100%; median difference in percent change between groups of 0%, 95% confidence interval, 0.0-6.7%) and 12 months (hypnotherapy, 85.7% improvement, 95% confidence interval, 66.7-94.4%; medications, 80% improvement, 95% confidence interval, 54.5-100%; median difference in percent change between groups of 0%, 95% confidence interval, -4.2% to -9.5%). CONCLUSION Both hypnotherapy and medications were associated with substantially improved urgency urinary incontinence at all follow-up. The study did not prove the noninferiority of hypnotherapy compared to medications at 2 months, the study's primary outcome. Hypnotherapy proved noninferior to medications at longer-term follow-up of 6 and 12 months. Hypnotherapy is a promising, alternative treatment for women with UUI.

Abstract
PURPOSE We investigated treatment satisfaction with flexible-dose fesoterodine in patients with overactive bladder (OAB) who were dissatisfied with previous anticholinergic therapy. MATERIALS AND METHODS The subjects were prescribed fesoterodine 4 mg for 4 weeks and fesoterodine 4 mg or 8 mg for another 8 weeks. The primary end point of this study was patients' satisfaction after 12 weeks of fesoterodine treatment on a five-point Likert scale. Secondary end points included a change in the number of daytime micturition, urgency incontinence episodes, urgency episodes, and nocturnal micturition in a 24-hour period from baseline to final assessment. RESULTS Overall, 84 patients were assigned to the treatment group in this study and 63 patients completed the 12-week treatment course. A final fesoterodine dose of 4 mg and 8 mg was used by 45 (71.4%) and 18 (28.6%) patients, respectively. The satisfaction and dissatisfaction rates at 12 weeks were 69.9% and 14.2%, respectively. Mean changes in the daytime micturitions (9.73 ± 4.72 vs. 7.76 ± 2.86), urgency episodes (7.73 ± 5.68 vs. 3.71 ± 4.09), and nocturnal micturitions (2.13 ± 1.36 vs. 1.68 ± 1.12) in 24 hours improved significantly with flexible-dose fesoterodine treatment (P < .05). Most adverse events were mild and none were severe. CONCLUSION The flexible dose fesoterodine represents an alternative treatment modality in patients with OAB who are dissatisfied with previous anticholinergic therapy in Korea.

Abstract
BACKGROUND Nearsightedness (myopia) causes blurry vision when one is looking at distant objects. Interventions to slow the progression of myopia in children include multifocal spectacles, contact lenses, and pharmaceutical agents. OBJECTIVES To assess the effects of interventions, including spectacles, contact lenses, and pharmaceutical agents in slowing myopia progression in children. SEARCH METHODS We searched CENTRAL; Ovid MEDLINE; Embase.com; PubMed; the LILACS Database; and two trial registrations up to February 2018. A top up search was done in February 2019. SELECTION CRITERIA We included randomized controlled trials (RCTs). We excluded studies when most participants were older than 18 years at baseline. We also excluded studies when participants had less than -0.25 diopters (D) spherical equivalent myopia. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methods. MAIN RESULTS We included 41 studies (6772 participants). Twenty-one studies contributed data to at least one meta-analysis. Interventions included spectacles, contact lenses, pharmaceutical agents, and combination treatments. Most studies were conducted in Asia or in the United States. Except one, all studies included children 18 years or younger. Many studies were at high risk of performance and attrition bias. Spectacle lenses: undercorrection of myopia increased myopia progression slightly in two studies; children whose vision was undercorrected progressed on average -0.15 D (95% confidence interval [CI] -0.29 to 0.00; n = 142; low-certainty evidence) more than those wearing fully corrected single vision lenses (SVLs). In one study, axial length increased 0.05 mm (95% CI -0.01 to 0.11) more in the undercorrected group than in the fully corrected group (n = 94; low-certainty evidence). Multifocal lenses (bifocal spectacles or progressive addition lenses) yielded small effect in slowing myopia progression; children wearing multifocal lenses progressed on average 0.14 D (95% CI 0.08 to 0.21; n = 1463; moderate-certainty evidence) less than children wearing SVLs. In four studies, axial elongation was less for multifocal lens wearers than for SVL wearers (-0.06 mm, 95% CI -0.09 to -0.04; n = 896; moderate-certainty evidence). Three studies evaluating different peripheral plus spectacle lenses versus SVLs reported inconsistent results for refractive error and axial length outcomes (n = 597; low-certainty evidence). Contact lenses: there may be little or no difference between vision of children wearing bifocal soft contact lenses (SCLs) and children wearing single vision SCLs (mean difference (MD) 0.20D, 95% CI -0.06 to 0.47; n = 300; low-certainty evidence). Axial elongation was less for bifocal SCL wearers than for single vision SCL wearers (MD -0.11 mm, 95% CI -0.14 to -0.08; n = 300; low-certainty evidence). Two studies investigating rigid gas permeable contact lenses (RGPCLs) showed inconsistent results in myopia progression; these two studies also found no evidence of difference in axial elongation (MD 0.02mm, 95% CI -0.05 to 0.10; n = 415; very low-certainty evidence). Orthokeratology contact lenses were more effective than SVLs in slowing axial elongation (MD -0.28 mm, 95% CI -0.38 to -0.19; n = 106; moderate-certainty evidence). Two studies comparing spherical aberration SCLs with single vision SCLs reported no difference in myopia progression nor in axial length (n = 209; low-certainty evidence). Pharmaceutical agents: at one year, children receiving atropine eye drops (3 studies; n = 629), pirenzepine gel (2 studies; n = 326), or cyclopentolate eye drops (1 study; n = 64) showed significantly less myopic progression compared with children receiving placebo: MD 1.00 D (95% CI 0.93 to 1.07), 0.31 D (95% CI 0.17 to 0.44), and 0.34 (95% CI 0.08 to 0.60), respectively (moderate-certainty evidence). Axial elongation was less for children treated with atropine (MD -0.35 mm, 95% CI -0.38 to -0.31; n = 502) and pirenzepine (MD -0.13 mm, 95% CI -0.14 to -0.12; n = 326) than for those treated with placebo (moderate-certainty evidence) in two studies. Another study showed favorable results for three different doses of atropine eye drops compared with tropicamide eye drops (MD 0.78 D, 95% CI 0.49 to 1.07 for 0.1% atropine; MD 0.81 D, 95% CI 0.57 to 1.05 for 0.25% atropine; and MD 1.01 D, 95% CI 0.74 to 1.28 for 0.5% atropine; n = 196; low-certainty evidence) but did not report axial length. Systemic 7-methylxanthine had little to no effect on myopic progression (MD 0.07 D, 95% CI -0.09 to 0.24) nor on axial elongation (MD -0.03 mm, 95% CI -0.10 to 0.03) compared with placebo in one study (n = 77; moderate-certainty evidence). One study did not find slowed myopia progression when comparing timolol eye drops with no drops (MD -0.05 D, 95% CI -0.21 to 0.11; n = 95; low-certainty evidence). Combinations of interventions: two studies found that children treated with atropine plus multifocal spectacles progressed 0.78 D (95% CI 0.54 to 1.02) less than children treated with placebo plus SVLs (n = 191; moderate-certainty evidence). One study reported -0.37 mm (95% CI -0.47 to -0.27) axial elongation for atropine and multifocal spectacles when compared with placebo plus SVLs (n = 127; moderate-certainty evidence). Compared with children treated with cyclopentolate plus SVLs, those treated with atropine plus multifocal spectacles progressed 0.36 D less (95% CI 0.11 to 0.61; n = 64; moderate-certainty evidence). Bifocal spectacles showed small or negligible effect compared with SVLs plus timolol drops in one study (MD 0.19 D, 95% CI 0.06 to 0.32; n = 97; moderate-certainty evidence). One study comparing tropicamide plus bifocal spectacles versus SVLs reported no statistically significant differences between groups without quantitative results. No serious adverse events were reported across all interventions. Participants receiving antimuscarinic topical medications were more likely to experience accommodation difficulties (Risk Ratio [RR] 9.05, 95% CI 4.09 to 20.01) and papillae and follicles (RR 3.22, 95% CI 2.11 to 4.90) than participants receiving placebo (n=387; moderate-certainty evidence). AUTHORS' CONCLUSIONS Antimuscarinic topical medication is effective in slowing myopia progression in children. Multifocal lenses, either spectacles or contact lenses, may also confer a small benefit. Orthokeratology contact lenses, although not intended to modify refractive error, were more effective than SVLs in slowing axial elongation. We found only low or very low-certainty evidence to support RGPCLs and sperical aberration SCLs.

Abstract
Bronchodilators, including long-acting muscarinic antagonists (LAMAs), improve airflow limitation and lung hyperinflation in patients with chronic obstructive pulmonary disease (COPD). While bronchodilators increase airway caliber and deflate the lungs, little is known about the effects of the local interaction between airway dilation and lung deflation on functional improvements resulting from bronchodilator therapy. This study aimed to explore whether lung deflation with increased airway volume in the upper and lower lung regions would produce different physiological responses to LAMA therapy. Using the clinical data of 41 patients with COPD who underwent spirometry and inspiratory computed tomography (CT) before and 1 year after LAMA treatment, we measured the 1-year change in the airway tree to lung volume percentage ratio (AWV%) for the right upper, middle, and lower lobes (RUL, RML, and RLL) and the left upper and lower lobes (LUL and LLL), and total airway count (TAC) identifiable on CT in relation to the forced expiratory volume in 1 s (FEV1 ). The results showed that LAMA treatment significantly increased the FEV1 and AWV% of the RUL, RML, RLL, LUL, and LLL. Increased AWV% in the RLL and LLL, but not in the RUL and LUL, was correlated with increased FEV1 . In the multivariate analysis, the increased AWV% in the RLL was associated with the increased FEV1 independent of the change in TAC in the RLL after treatment. This is the first study to show that the physiological improvements after bronchodilator treatment in COPD could be mainly due to the combination of regional deflation and increased airway volume of the lower lobes.

Abstract
Muscarinic acetylcholine receptors (mAChR) play important roles in regulating complex behaviors such as cognition, movement, and reward, making them ideally situated as potential drug targets for the treatment of several brain disorders. Recent advances in the discovery of subtype-selective allosteric modulators for mAChRs has provided an unprecedented opportunity for highly specific modulation of signaling by individual mAChR subtypes in the brain. Recently, mAChR allosteric modulators have entered clinical development for Alzheimer's disease (AD) and schizophrenia, and have potential utility for other brain disorders. However, mAChR allosteric modulators can display a diverse array of pharmacological properties, and a more nuanced understanding of the mAChR will be necessary to best translate preclinical findings into successful clinical treatments.

Abstract
Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disease characterized by cough, dyspnea, and sputum production caused by inhalation of harmful chemicals, such as tobacco smoke. COPD should be suspected in patients with a significant smoking history, shortness of breath, and sputum production. The diagnosis is made by spirometry. A forced expiratory volume in the first second of expiration to forced vital capacity (FEV1/FVC) ratio of less than 0.7 after bronchodilator administration confirms the diagnosis. Therapy for patients with stable COPD should include a bronchodilator, either a long-acting beta2-agonist (LABA) or a long-acting muscarinic antagonist (LAMA). For patients who continue to experience dyspnea with a single bronchodilator, dual therapy with a LABA and LAMA is appropriate. For patients with continued exacerbations, inhaled corticosteroids can be added to LABA-LAMA therapy. Acute exacerbations are characterized by a worsening of symptoms that requires additional therapy. Short-acting beta2-agonists with or without short-acting muscarinic antagonists are the basic therapy for acute exacerbations of COPD. Systemic glucocorticoids have been shown to shorten exacerbations and improve lung function. Antibiotics have been shown to reduce rates of treatment failure and sputum purulence. Noninvasive mechanical ventilation is preferred for patients with respiratory failure.

Abstract
Introduction Pharmacotherapy for overactive bladder (OAB) is generally associated with low rates of persistence and adherence. This study was conducted to explore the patient journey in a UK primary care setting (experiences, perceptions, attitudes, and levels of engagement and expectations) and identify self-reported reasons for patient non-adherence and/or non-persistence to medications for OAB. Methods This was a qualitative, non-interventional study involving one-to-one semi-structured, face-to-face or phone interviews with individuals aged 40–80 years, diagnosed with OAB, and currently taking, or having taken, either antimuscarinic or β3-adrenoceptor agonist medications within the last 12 months. Thematic analyses of interview transcripts identified themes surrounding the participants’ experiences with OAB. Results A total of 20 interviews were conducted (face-to-face, n = 13; telephone, n = 7). Interviews from five men and 13 women (mean age 70 years) were included in the final analysis. The most common OAB symptoms reported included urgency, frequency, incontinence and nocturia. Several key themes of factors influencing persistence and/or adherence to prescribed OAB medication were identified: patients’ attitude and condition adaptation behaviour; support with treatment; unmet efficacy/tolerability expectations; drug/condition hierarchy. Non-adherence and/or non-persistence to OAB medication was largely intentional, with patients balancing side effects against perceived clinical benefits. Perceived lack of efficacy was the primary reason for discontinuing treatment. Other factors cited included side effects of medication (either experienced or a fear of future effects), a general aversion to long-term medication taking, drug/condition hierarchy relative to other comorbidities, and limited healthcare professional (HCP) support/engagement. Patients expressed condition adaptation behaviours to help self-manage their condition. Conclusion Persistence and adherence to OAB medication may be suboptimal. HCPs might be able to improve persistence and adherence by fostering realistic treatment expectations and scheduling regular medication reviews. These measures may help optimise patient care and support more adherent behaviours, thus minimising the impact of undertreated OAB on patient quality of life.

Abstract
Deterioration or inborn malformations of the cardiac conduction system (CCS) interfere with proper impulse propagation in the heart and may lead to sudden cardiac death or heart failure. Patients afflicted with arrhythmia depend on antiarrhythmic medication or invasive therapy, such as pacemaker implantation. An ideal way to treat these patients would be CCS tissue restoration. This, however, requires precise knowledge regarding the molecular mechanisms underlying CCS development. Here, we aimed to identify regulators of CCS development. We performed a compound screen in zebrafish embryos and identified tolterodine, a muscarinic receptor antagonist, as a modifier of CCS development. Tolterodine provoked a lower heart rate, pericardiac edema, and arrhythmia. Blockade of muscarinic M3, but not M2, receptors induced transcriptional changes leading to amplification of sinoatrial cells and loss of atrioventricular identity. Transcriptome data from an engineered human heart muscle model provided additional evidence for the contribution of muscarinic M3 receptors during cardiac progenitor specification and differentiation. Taken together, we found that muscarinic M3 receptors control the CCS already before the heart becomes innervated. Our data indicate that muscarinic receptors maintain a delicate balance between the developing sinoatrial node and the atrioventricular canal, which is probably required to prevent the development of arrhythmia.

Abstract
Chronic heart and lung diseases are very common in the elderly population. The combination of chronic heart failure and chronic obstructive pulmonary disease (COPD) is also common and, according to current guidelines, these patients should be treated for both diseases. In patients with heart failure, beta-blockers are very important drugs because their use is associated with significantly improved morbidity and mortality. These beneficial effects were documented in patients with and without COPD, although theoretically there is a risk for bronchoconstriction, particularly with non-beta1 selective blockers. In COPD patients, long-acting sympathomimetics (LABA) improve lung function, dyspnea, and quality of life and their combination with a beta-blocker makes sense from a pharmacological and a clinical point of view, because any potential arrhythmogenic effects of the LABA will be ameliorated by the beta-blocker. Inhaled tiotropium, a long-acting muscarinic antagonist (LAMA), has been extensively investigated and no safety concerns were reported in terms of cardiac adverse effects. The same applies for the other approved LAMA preparations and LAMA-LABA combinations. Severe COPD causes air-trapping with increasing pressures in the thorax, leading to limitations in blood return into the thorax from the periphery of the body. This causes a decrease in stroke volume and cardiac index and is associated with dyspnea. All these adverse effects can be ameliorated by potent anti-obstructive therapy as recently shown by means of a LABA-LAMA combination.

Abstract
Tiotropium/olodaterol (Stiolto® Respimat®; Spiolto® Respimat®) is an inhaled fixed-dose combination of the long-acting muscarinic antagonist tiotropium bromide (hereafter referred to as tiotropium) and the long-acting β2-adrenergic agonist olodaterol. It is available in several countries, including the USA, Japan, China and those of the EU, where it is indicated for the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). The efficacy of tiotropium/olodaterol 5/5 μg/day in patients with COPD was evaluated in phase III or IV trials of 6-52 weeks' duration. Tiotropium/olodaterol improved lung function to a greater extent than each of its individual components or placebo in 12- and 52-week trials. In 6-week trials, tiotropium/olodaterol provided greater lung function benefits over 24 h than the individual components, placebo or twice-daily fluticasone propionate/salmeterol. Tiotropium/olodaterol also demonstrated beneficial effects on health-related quality of life (HR-QoL), dyspnoea, inspiratory capacity, exercise endurance and the need for rescue medication. In an 8-week open-label trial, umeclidinium/vilanterol was superior to tiotropium/olodaterol for the primary endpoint of trough forced expiratory volume in 1 s. The tolerability profile of tiotropium/olodaterol was generally similar to that of the individual components. In conclusion, tiotropium/olodaterol provides a useful option for the maintenance treatment of COPD, with the convenience of once-daily administration via a single inhaler.

Abstract
This case report describes a probable unilateral accommodation spasm in a 10 year-old girl with no significant medical history. The right eye showed decreased visual acuity, 0.2 to 0.6 for far distance and 0.125 for near distance. Refraction without cycloplegia showed myopization up to -6 and cycloplegic refraction of+0.50. The patient had normal ocular motility, orthophoria, normal pupil reflex, normal anterior and posterior segments, normal optical coherence tomography. Neurophysiological tests and brain magnetic resonance imaging were all normal. Treatment with atropine 1% drops for 15 days improved distance visual acuity to 0.8. Accommodation spasm is a rare condition and is usually bilateral. Imaging test are necessary because it may be associated with ocular or head trauma. Treatment consists of cycloplegic drugs (atropine, cyclopentolate); however, there is no defined guideline.

Abstract
BACKGROUND Whether the beneficial effects of long-acting muscarinic antagonists (LAMA) are better than those of long-acting β2 agonist/corticosteroids (LABA/ICS) in preventing exacerbations in chronic obstructive pulmonary disease (COPD) remains unclear. This study aimed to assess the risk of exacerbations in moderate to severe COPD patients receiving LAMA versus LABA/ICS. METHODS We retrospectively reviewed the medical records of patients diagnosed with COPD (2008-2010). The inclusion criteria were age ≥ 40 years, forced expiratory volume in 1 second (FEV1) 30% to 80% of predicted value and at least three prescriptions for COPD medication, including LAMA or LABA/ICS. RESULTS Of the 557 COPD patients screened, 90 patients were enrolled in the analysis. The demographic characteristics of patients receiving LABA/ICS or LAMA were similar. The all exacerbation rates was significantly higher in patients with global initiative for chronic obstructive lung disease stage II COPD treated with LABA/ICS than in those treated with LAMA (p = 0.001), regardless of previous exacerbation history. Patients with previous exacerbation history showed an independent increase in the risk of moderate or severe exacerbation compared with those without exacerbation history (hazard ratio 3.86, 95% CI 1.75-8.53, p = 0.001). CONCLUSION In comparison with LABA/ICS, LAMA is beneficial in reducing exacerbation risk for moderate COPD. Previous exacerbation history independently predicts the future risk of exacerbation regardless of treatment.

Abstract
IMPORTANCE There is concern that long-acting muscarinic antagonists increase cardiovascular morbidity or mortality in patients with chronic obstructive pulmonary disease (COPD). OBJECTIVE To determine the cardiovascular safety (noninferiority) and efficacy (superiority) of aclidinium bromide, 400 μg twice daily, in patients with COPD and cardiovascular disease or risk factors. DESIGN, SETTING, AND PARTICIPANTS Multicenter, randomized, placebo-controlled, double-blind, parallel-design study conducted at 522 sites in North America. A total of 3630 patients with moderate to very severe COPD and either a history of cardiovascular disease or at least 2 atherothrombotic risk factors were randomized; follow-up occurred for up to 3 years until at least 122 major adverse cardiovascular events (MACE) occurred. The first patient was enrolled on October 16, 2013 and the last on August 22, 2016. The final patient completed follow-up on September 21, 2017. INTERVENTIONS Patients were randomized to receive aclidinium (n = 1812) or placebo (n = 1818) by dry-powder inhaler, twice daily for up to 3 years. MAIN OUTCOMES AND MEASURES The primary safety end point was time to first MACE over up to 3 years (hazard ratio [HR] 1-sided 97.5% CI noninferiority margin = 1.8). The primary efficacy end point was the annual COPD exacerbation rate during the first year of treatment. Secondary outcomes included an expanded MACE definition (time to first MACE or serious cardiovascular event of interest) and annual rate of exacerbations requiring hospitalization. RESULTS Among 3589 patients analyzed (mean age, 67.2 years; 58.7% male), 2537 (70.7%) completed the study. Of these, 69 (3.9%) aclidinium and 76 (4.2%) placebo patients had a MACE (HR, 0.89; 1-sided 97.5% CI, 0-1.23); the expanded MACE definition included 168 (9.4%) aclidinium vs 160 (8.9%) placebo patients with events (HR, 1.03; 1-sided 97.5% CI, 0-1.28). Annual moderate to severe exacerbation rates (aclidinium, 0.44; placebo, 0.57; rate ratio, 0.78; 2-sided 95% CI, 0.68-0.89; P < .001) and rate of exacerbations requiring hospitalization (aclidinium, 0.07; placebo, 0.10; rate ratio, 0.65; 2-sided 95% CI, 0.48-0.89; P = .006) decreased significantly with aclidinium vs placebo. The most common adverse events were pneumonia (aclidinium, 109 events [6.1%]; placebo, 105 events [5.8%]), urinary tract infection (aclidinium, 93 events [5.2%]; placebo, 89 events [5.0%]), and upper respiratory tract infection (aclidinium, 86 events [4.8%]; placebo, 101 events [5.6%]). CONCLUSIONS AND RELEVANCE Among patients with COPD and increased cardiovascular risk, aclidinium was noninferior to placebo for risk of MACE over 3 years. The rate of moderate to severe COPD exacerbations was reduced over the first year. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01966107.

Abstract
OBJECTIVES To determine if symptoms changed after changing chronic obstructive pulmonary disease (COPD) triple-therapy inhalers to a less expensive regimen. STUDY DESIGN Retrospective observational case-series analysis. METHODS A quality improvement program was instituted to reduce drug costs associated with COPD inhalers between fall 2016 and spring 2017. Patients identified as taking an inhaled corticosteroid (ICS)/long-acting β agonist (LABA) inhaler and a long-acting muscarinic agonist (LAMA) inhaler were changed to a LAMA/LABA inhaler and an ICS inhaler. Symptoms were assessed at baseline and subsequent follow-up using the COPD Assessment Test (CAT), with lower scores representing better symptom control. Then, a retrospective observational case-series analysis of 118 patient charts was completed. The primary outcome was mean difference in CAT score. Data were analyzed using a paired t test with an α value of 0.05. RESULTS Of 118 patients included in the quality improvement program, 19 met the inclusion and exclusion criteria. The mean (SD) CAT score prior to the change was 15.53 (5.36), and the mean (SD) CAT score after the change was 14.68 (6.98). Symptom scores improved after the change, with an average difference in postchange and prechange CAT scores of -0.84, although this difference was not statistically significant (95% CI, -3.57 to 1.89; P = .525). CONCLUSIONS Based on the results of this observational review, changing COPD triple-therapy inhalers did not result in a significant change in patient-reported symptom scores. Patients may use triple-therapy inhalers that are most affordable without a significant change in symptom control.
