Abstract
We ranked businesses for their ability to fill gaps in the AED landscape. 23% of OHCAs in public, and 4% in homes, were within 100 m of an existing AED. Many businesses can simultaneously improve coverage of arrests in public and homes. Rankings were largely robust to the coverage radius used (100 m, 200 m, and 500 m). Even if all 5006 business locations hosted AEDs, large gaps in OHCA coverage remain.

Abstract
OBJECTIVE The COVID-19 pandemic prompted health systems to rapidly adopt telehealth for clinical care. We examined the impact of demography, subspecialty characteristics, and broadband availability on the utilization of telehealth in pediatric populations before and after the early period of the COVID-19 pandemic. METHODS Outpatients scheduled for subspecialty visits at sites affiliated with a single quaternary academic medical center between March-June 2019 and March-June 2020 were included. The contribution of demographic, socioeconomic, and broadband availability to visit completion and telehealth utilization were examined in multivariable regression analyses. RESULTS Among visits scheduled in 2020 compared to 2019, in-person visits fell from 23,318 to 11,209, while telehealth visits increased from 150 to 7,675. Visits among established patients fell by 15% and new patients by 36% (P < .0001). Multivariable analysis revealed that completed visits were reduced for Hispanic patients and those with reduced broadband; high income, private non-HMO insurance, and those requesting an interpreter were more likely to complete visits. Those with visits scheduled in 2020, established patients, those with reduced broadband, and patients older than 1 year were more likely to complete TH appointments. Cardiology, oncology, and pulmonology patients were less likely to complete scheduled TH appointments. CONCLUSIONS Following COVID-19 onset, outpatient pediatric subspecialty visits shifted rapidly to telehealth. However, the impact of this shift on social disparities in outpatient utilization was mixed with variation among subspecialties. A growing reliance on telehealth will necessitate insights from other healthcare settings serving populations of diverse social and technological character.

Abstract
Knowing precisely where a spacecraft lands on Mars is important for understanding the regional and local context, setting, and the offset between the inertial and cartographic frames. For the InSight spacecraft, the payload of geophysical and environmental sensors also particularly benefits from knowing exactly where the instruments are located. A ~30 cm/pixel image acquired from orbit after landing clearly resolves the lander and the large circular solar panels. This image was carefully georeferenced to a hierarchically generated and coregistered set of decreasing resolution orthoimages and digital elevation models to the established positive east, planetocentric coordinate system. The lander is located at 4.502384°N, 135.623447°E at an elevation of -2,613.426 m with respect to the geoid in Elysium Planitia. Instrument locations (and the magnetometer orientation) are derived by transforming from Instrument Deployment Arm, spacecraft mechanical, and site frames into the cartographic frame. A viewshed created from 1.5 m above the lander and the high-resolution orbital digital elevation model shows the lander is on a shallow regional slope down to the east that reveals crater rims on the east horizon ~400 m and 2.4 km away. A slope up to the north limits the horizon to about 50 m away where three rocks and an eolian bedform are visible on the rim of a degraded crater rim. Azimuths to rocks and craters identified in both surface panoramas and high-resolution orbital images reveal that north in the site frame and the cartographic frame are the same (within 1°).

Abstract
A number of psychological variables bearing on the process of adjustment to acquired visual loss are examined conceptually and empirically in an attempt to clarify their relationships and to develop a testable model of adjustment which might enable rehabilitation specialists to identify clients with special problems, evaluate the effectiveness of rehabilitation programs, and determine the role of psychological factors in the context of skill acquisition. The model presented offers an alternative to existing psychodynamic models in that it is in principle a testable one. Preliminary analysis of data has resulted in the devising of a questionnaire tentatively called the Nottingham Adjustment Scale, which practitioners and researchers are encouraged to use.

Abstract
The objectives of this study were to characterize relationships between water and paddlefish Polyodon spathula dentary Sr:Ca, δ18 O and stable hydrogen isotope ratio (δD) to determine the accuracy with which individual P. spathula could be assigned to their collection locations using dentary-edge Sr:Ca, δD and δ18 O. A laboratory experiment was also conducted to determine whether dentary Sr:Ca in age 0 year P. spathula would reflect shifts in water Sr:Ca to which fish were exposed. Significant linear relationships between water and dentary Sr:Ca, δD and δ18 O were observed, although the relationship between water and dentary δ18 O was weaker than those for Sr:Ca and δD. Classification success for individual fish to collection locations that differed in water Sr:Ca, δD and δ18 O ranged from 86 to 100% based on dentary-edge Sr:Ca, δD and δ18 O. Dentary Sr:Ca increased significantly in laboratory-reared age 0 year P. spathula following 4 weeks of exposure to elevated water Sr:Ca; dentary Sr:Ca of fish held in water with elevated Sr:Ca was also significantly higher than that of control fish reared in ambient laboratory water. Results indicated that P. spathula dentaries reflect water signatures for commonly-applied natural chemical markers and strongly suggest that dentary microchemistry and stable-isotopic compositions will be applicable for reconstructing P. spathula environmental history in locations where sufficient spatial differences in water chemistry occur.

Abstract
Bispectral index (BIS) monitor is a neurophysiological monitoring device which continually analyses a patient's electroencephalogram during sedation and general anaesthesia to assess the level of consciousness and depth of anaesthesia. BIS monitoring, whilst performing sleep nasendoscopy (using midazolam and propofol), has helped validate depth of sedation and allowed comparison with levels of sedation of control patients during natural sleep. A prospective study of 30 patients with snoring undergoing sleep nasendoscopy with BIS monitoring was conducted. BIS monitoring was recorded throughout the procedure and assessment of snoring was made at the appropriate level of sedation and snoring. BIS values were compared with control patients. The 30 patients undergoing sleep nasendoscopy had average BIS values ranging from 50.72 to 61.2. Similar results were seen with BIS and oxygen saturation in the control group. BIS monitoring provides an adjunct to the assessment of sleep nasendoscopy in determining the level of sedation required for snoring assessment. Comparable BIS values and oxygen saturation levels were obtained between controls and patients during sedation-induced sleep, thus validating the role of sleep nasendoscopy.

Abstract
Complementary but independent medium-energy and low-energy ion scattering studies of the (0001) surfaces of V(2)O(3) films grown on Pd(111), Au(111) and Cu(3)Au(100) reveal a reconstructed full O(3)-layer termination creating a VO(2) surface trilayer. This structure is fully consistent with previous calculations based on thermodynamic equilibrium at the surface during growth, but contrasts with previous suggestions that the surface termination comprises a complete monolayer of vanadyl (V=O) species.

Abstract
Dandruff is a common problem in approximately 30% of the world's population. Reports in the literature regarding treatment of this condition with various antidandruff shampoos usually report the level of active ingredient within the formulation. However, we propose that a more important parameter relating to antidandruff efficacy is the amount of active ingredient delivered to the scalp from the shampoo. This report describes the results from two studies designed to investigate the relationship between the level of zinc pyrithione (ZnPTO) deposited onto the scalp and the resultant scalp condition. A double-blind randomized vehicle-controlled clinical study comparing three shampoos - a vehicle, a low-depositing ZnPTO shampoo and a high-depositing ZnPTO shampoo - was carried out in the U.K. with 53 panelists with dandruff or mild-to-moderate seborrheic dermatitis of the scalp. Both shampoos containing ZnPTO were significantly superior in antidandruff efficacy to the vehicle. Furthermore, the high-depositing ZnPTO shampoo was significantly superior compared with the low-depositing ZnPTO shampoo in terms of both antidandruff efficacy and antimycotic activity. Antidandruff performance and antimycotic activity of ZnPTO-containing shampoos is highly dependent on the amount of active ingredient delivered to the scalp. Furthermore, careful manipulation of the formulation parameters of an antidandruff shampoo can result in enhanced levels of delivery of the active ingredient without having to increase the level of active ingredient within the formulation.

Abstract
The energy spectrum associated with scattering of 100 keV H+ ions from the outermost few atomic layers of Cu(111) in different scattering geometries provides direct evidence of trajectory-dependent electronic energy loss. Theoretical simulations, combining standard Monte Carlo calculations of the elastic scattering trajectories with coupled-channel calculations to describe inner-shell ionization and excitation as a function of impact parameter, reproduce the effects well and provide a means for far more complete analysis of medium-energy ion scattering data.

Abstract
The growth and annealing behavior of ultrathin Au films on Pd{111} were monitored with scanning tunneling microscopy (STM) and medium energy ion scattering (MEIS). The adsorption of acetic acid on both clean and deliberately carbon-contaminated bimetallic surfaces was investigated with reflection absorption infrared spectroscopy (RAIRS) and temperature-programmed desorption (TPD). We report that the surface chemistry of acetic acid is strongly modified by the presence of Au in the bimetallic surface which acts both to stabilize adsorbed acetate and to decrease the tendency of acetic acid to decompose on adsorption to produce adsorbed carbon. The adsorption of acetic acid at 300 K is found to cause measurable segregation of Pd to the surface for all surface compositions tested.

Abstract
OBJECTIVE The paper reviews the experience with the EmOC process indicators, and evaluates whether the indicators serve the purposes for which they were originally created - to gather and interpret relatively accessible data to design and implement EmOC service programs. METHOD We review experience with each of the 6 process indicators individually, and monitoring change over time, at the level of the facility and at the level of a region or country. We identify problems encountered in the field with data collection and interpretation. RESULT While they have strengths and weaknesses, the process indicators in general serve the purposes for which they were developed. The data are easily collected, but some data problems were identified. We recommend several relatively minor modifications to improve data collection, interpretation and utility. CONCLUSIONS The EmOC process indicators have been used successfully in a wide variety of settings. They describe vital elements of the health system and how well that system is functioning for women at risk of dying from major obstetric complications.

Abstract
OBJECTIVE The 5-year project in the province of Sofala was designed to improve access, quality and utilization of emergency obstetric care (EmOC) by strengthening rural hospitals and health centers and ultimately the health system's capacity to respond to emergencies more quickly and effectively. METHODS Implementation consisted of attention to infrastructure, human resource development, transportation and communication systems, and management. Specific management aspects that were targeted for improvement included: supportive supervision, logistics for supplies, equipment and drugs, record keeping, monitoring and evaluation, and quality improvement techniques such as maternal death audits. RESULTS Access to EmOC improved with an increase in the number of fully functional EmOC facilities from 4 to 18. The number of women with obstetric complications who were admitted for treatment in participating facilities tripled, and the proportion of those women dying declined by half. CONCLUSIONS Close collaboration and partnership with the provincial health directorate make the sustainability of many results likely while the replication of much of the Sofala model to other provinces is promising for the national strategy to reduce maternal mortality.

Abstract
The first measurements of double-hadron production in deep-inelastic scattering within the nuclear medium were made with the HERMES spectrometer at DESY HERA using a 27.6 GeV positron beam. By comparing data for deuterium, nitrogen, krypton, and xenon nuclei, the influence of the nuclear medium on the ratio of double-hadron to single-hadron yields was investigated. Nuclear effects on the additional hadron are clearly observed, but with little or no difference among nitrogen, krypton, or xenon, and with smaller magnitude than effects seen on previously measured single-hadron multiplicities. The data are compared with models based on partonic energy loss or prehadronic scattering and with a model based on a purely absorptive treatment of the final-state interactions. Thus, the double-hadron ratio provides an additional tool for studying modifications of hadronization in nuclear matter.

Abstract
OBJECTIVE This paper examines the availability of basic and comprehensive emergency obstetric care (EmOC), interventions used to treat direct obstetric complications. Determining what interventions are provided in health facilities is the first priority in analyzing a country's capabilities to treat obstetric emergencies. There are eight key interventions, six constitute basic EmOC and all eight comprehensive EmOC. METHODS AND RESULTS Based on data from 24 needs assessments, the following global patterns emerge: comprehensive EmOC facilities are usually available to meet the recommended minimum number for the size of the population, basic EmOC facilities are consistently not available in sufficient numbers, both in countries with high and moderate levels of maternal mortality, and the majority of facilities offering maternity services provide only some interventions indicating an unrealized potential. CONCLUSION Upgrading maternities, health centers and hospitals to at least basic EmOC status would be a major contributing step towards maternal mortality reduction in resource-poor countries.

Abstract
OBJECTIVE This paper argues for an additional indicator for measuring progress of the Millennium Development Goal for maternal health-the availability of emergency obstetric care. METHODS MDG monitoring will be based on two indicators: the maternal mortality ratio and the proportion of births attended by skilled personnel. Strengths and weaknesses of a third indicator are discussed RESULTS The availability of EmOC measures the capacity of the health system to respond to direct obstetric complications. Benefits to using this additional indicator are its usefulness in determining an adequate distribution of services and showing management at all levels what life-saving interventions are not being provided, and stimulate thought as to why. It can reflect programmatic changes over a relatively short period of time and data requirements are not onerous. CONCLUSION A measure of strength of the health system is important since many interventions depend on the health system for their implementation.

Abstract
OBJECTIVE This paper examines the frequency with which a set of life-saving interventions or signal functions was performed to treat major obstetric complications. METHODS AND RESULTS The basic signal functions include parenteral antibiotics, anticonvulsants and oxytocics, and the procedures of manual removal of the placenta, removal of retained uterine products, and assisted vaginal delivery. Comprehensive functions include the six basic functions, cesarean delivery, and blood transfusions. Data from 1906 health facilities in 13 countries indicate that the most likely functions to be reported are oxytocics and antibiotics. The basic function least likely to be reported is assisted vaginal delivery. Many of the facilities surveyed did not have the infrastructure to perform operations or provide blood transfusions. CONCLUSIONS These data can help governments allocate their budgets appropriately, help policy makers and planners identify systemic bottlenecks and prioritize solutions. Monitoring the performance of the functions informs us of the capacity of the health system to provide key interventions when obstetric emergencies occur.

Abstract
OBJECTIVE With support from the Averting Maternal Death and Disability (AMDD) Program, CARE began the FEMME Project in 2000 to increase access and utilization of emergency obstetric care (EmOC) services for the approximately 48,000 pregnant women in the northern provinces of Ayacucho. METHODS The project targeted 5 facilities with a comprehensive package of interventions designed to improve capacity to provide quality EmOC services and to promote a human rights approach in health care. Key program activities included improvements in infrastructure, human resources capacity development, development of service standards and protocols, quality improvement activities, and promoting a rights-based approach to health. RESULTS By the end of the project, northern Ayacucho had 6 functioning EmOC facilities: 3 comprehensive (including a non-FEMME project facility) and 3 basic. This exceeds the UN minimum recommendation of 5 EmOC facilities per 500,000 population. Other changes in the UN process indicators indicate an increase in quality and utilization of EmOC services. Met need for EmOC increased significantly from 30% in 2000 to a high of 84% in 2004. Case fatality rates declined and the number of maternal deaths in the entire region declined. CONCLUSION CARE's work in Ayacucho made an impact on policies and programs related to EmOC throughout the region. Within CARE, project experiences have supported maternal health programs particularly in the Latin American/Caribbean region.

Abstract
The Hermes experiment has investigated the tensor spin structure of the deuteron using the 27.6 GeV/c positron beam of DESY HERA. The use of a tensor-polarized deuteron gas target with only a negligible residual vector polarization enabled the first measurement of the tensor asymmetry A(d)zz and the tensor structure function b(d)1 for average values of the Bjorken variable 0.01< <x> <0.45 and of the negative of the squared four-momentum transfer 0.5 GeV2 < <Q2> <5 GeV2. The quantities A(d)zz and b(d)1 are found to be nonzero. The rise of b(d)1 for decreasing values of x can be interpreted to originate from the same mechanism that leads to nuclear shadowing in unpolarized scattering.

Abstract
OBJECTIVE To monitor changes in the utilization and need for obstetric care between 1995 and 1998 at three hospitals in the highlands of Guatemala. METHODS We collected data on 5300 obstetric admissions from maternity registries and selected 10 indicators to measure intermediate outcomes. RESULTS Utilization of services increased at some or all hospitals as measured by the number of obstetric admissions, proportion of births in facilities, and cesarean deliveries as a proportion of all births. We observed increases in the proportion of women expected to have obstetric complications who were treated at each hospital and in the proportion of women with obstetric complications who were referrals. The changes in patient profile reflect increased service utilization and accessibility among women who traditionally used the health system the least. CONCLUSIONS Positive changes in these indicators are likely to be associated with a reduction in maternal mortality. Without a control area, we cannot be sure of a cause and effect relationship between outcomes and interventions, nevertheless, maternity registry data offer an inexpensive source of information for facilities to monitor changes.

Abstract
The UN process indicators are used to assess the availability, utilization and quality of emergency obstetric care (EmOC). Needs assessments for EmOC in Bolivia, El Salvador and Honduras show reasonable availability of comprehensive EmOC facilities for their population sizes, but a scarcity of basic facilities. Utilization rates among women with obstetric complications are high in El Salvador and Honduras. Case fatality rates tend to be below 1% in all three countries, but the more rural areas in each have poorer indicators.

Abstract
High volume air sampling in the Canadian Prairies was used to characterize atmospheric concentrations for 10 herbicides (alachlor, atrazine, ethalfluralin, metolachlor, 2,4-D, dicamba, bromoxynil, MCPA, trifluralin, and triallate) along a 500-km north-south transect. Atmospheric concentration measurements at various altitudes identified that of the six herbicides present in the highest concentrations, triallate was strongly influenced by local sources, while 2,4-D, dicamba, bromoxynil, MCPA and trifluralin were dominated by regional atmospheric transport. Concentrations of the herbicides measured at various altitudes were compared with dry deposition rates measured using a dry/wet deposition sampler and used to calculate deposition velocities V(d). The primary atmospheric transport mechanism for MCPA and bromoxynil was shown to be adsorption to particles dispersed in the atmosphere, with the same mechanism also confirmed for 2,4-D and dicamba, while trifluralin was shown to be transported mainly in the gas phase. This method of calculation indicated that transportation of triallate was influenced by particle adsorption. Weekly maximum atmospheric loadings of the major herbicides present in the Prairies were estimated to range from 73 kg for trifluralin to 541 kg for 2,4-D.

Abstract
Single-spin asymmetries for semi-inclusive electroproduction of charged pions in deep-inelastic scattering of positrons are measured for the first time with transverse target polarization. The asymmetry depends on the azimuthal angles of both the pion (phi) and the target spin axis (phi(S)) about the virtual-photon direction and relative to the lepton scattering plane. The extracted Fourier component sin((phi+phi(S))(pi)(UT) is a signal of the previously unmeasured quark transversity distribution, in conjunction with the Collins fragmentation function, also unknown. The component sin((phi-phi(S)(pi)(UT) arises from a correlation between the transverse polarization of the target nucleon and the intrinsic transverse momentum of quarks, as represented by the previously unmeasured Sivers distribution function. Evidence for both signals is observed, but the Sivers asymmetry may be affected by exclusive vector meson production.

Abstract
Double-spin asymmetries of semiinclusive cross sections for the production of identified pions and kaons have been measured in deep inelastic scattering of polarized positrons on a polarized deuterium target. Five helicity distributions including those for three sea quark flavors were extracted from these data together with reanalyzed previous data for identified pions from a hydrogen target. These distributions are consistent with zero for all three sea flavors. A recently predicted flavor asymmetry in the polarization of the light quark sea appears to be disfavored by the data.

Spin-dependent lepton-nucleon scattering data have been used to investigate the validity of the concept of quark-hadron duality for the spin asymmetry A1. Longitudinally polarized positrons were scattered off a longitudinally polarized hydrogen target for values of Q2 between 1.2 and 12 GeV2 and values of W2 between 1 and 4 GeV2. The average double-spin asymmetry in the nucleon resonance region is found to agree with that measured in deep-inelastic scattering at the same values of the Bjorken scaling variable x. This finding implies that the description of A1 in terms of quark degrees of freedom is valid also in the nucleon resonance region for values of Q2 above 1.6 GeV2.

Abstract
Exclusive coherent and incoherent electroproduction of the rho(0) meson from 1H and 14N targets has been studied at the HERMES experiment as a function of coherence length (l(c)), corresponding to the lifetime of hadronic fluctuations of the virtual photon, and squared four-momentum of the virtual photon (-Q2). The ratio of 14N to 1H cross sections per nucleon, called nuclear transparency, was found to increase (decrease) with increasing l(c) for coherent (incoherent) rho(0) electroproduction. For fixed l(c), a rise of nuclear transparency with Q2 is observed for both coherent and incoherent rho(0) production, which is in agreement with theoretical calculations of color transparency.

Abstract
The purpose of this study was to examine whether coping with pain changed immediately and one year after a self-care intervention for school-age children and adolescents with sickle cell disease (SCD). Sixty-five children and 32 adolescents attended an educational program for living with SCD. They were then randomly assigned to relaxation, art therapy or attention-control groups. Coping was measured before, after the intervention, and 12 months later. Thirty-three children and 14 adolescents completed the one year follow-up. Although there was no significant increase in the overall number of coping strategies school-age children and adolescents used from baseline to 12 months, there was a significant increase in those strategies specifically targeted by the intervention. For adolescents, there was a significant increase in the total number of coping scores used before the intervention and one year later. When compared to well African-American adolescents, overall coping scores in this sample were significantly lower. Health care utilization related to clinic visits, emergency department visits and hospitalizations decreased significantly for all participants in the study.

Abstract
Computerised dynamic posturography (CDP) can be used as an early marker of recovery to street fitness in patients undergoing ambulatory surgery. We studied three groups of patients undergoing nasal surgery. The goal of this study was to determine whether recovery, as assessed by CDP, is more rapid in patients having nasal surgery under sedation coupled with local anaesthesia or those having surgery under general anaesthesia. We further assessed the acceptability of sedation accompanied by local anaesthesia. A control group was included to determine if there is a learning curve to posturography. There was no difference between the two study groups in terms of balance. Balance was not significantly impaired at 3 h postoperative testing.

Abstract
ISSUES AND PURPOSE To evaluate the characteristics of vaso-occlusive episodes, home management of pain and its impact on the daily activities, and a diary as a method of data collection. DESIGN AND METHODS Forty-six adolescents and 75 children were asked to complete daily diaries during the intervention period of a larger study. RESULTS Mild pain was recorded 95% of the time; moderate pain, 3%; and severe pain, 1%. The pattern and location of pain varied greatly. Adolescents used more interventions than did children. When pain intensity was mild, 80% of the children/adolescents maintained school, social, and home activities, but decreased play/sport activities. When pain intensity was high, they decreased their participation in all activities. PRACTICE IMPLICATIONS Sickle cell pain episodes are unpredictable and highly variable. Diaries can enhance children's and adolescents' documentation and communication about their pain experiences.

Abstract
There is evidence for inhibitory effects of adrenocorticosteroids on serotonergic (5-HT) activity. However, in depression the relationship between altered cortisol levels and brain 5-HT function remains to be clarified. The aim of this study was to investigate whether hypothalamic-pituitary-adrenal (HPA) axis hyperactivity is associated with 5-HT dysfunction in depressed patients, especially in those with suicidal behaviour. Cortisol levels following the dexamethasone suppression test (DST, 1 mg PO) and prolactin, corticotropin and cortisol responses to the d-fenfluramine test (d-FEN, 45 mg PO) - a specific 5-HT releaser/uptake inhibitor - were measured in 71 drug-free DSM-IV major depressed inpatients (40 with a history of suicide attempt, 31 without) and 34 hospitalized healthy control subjects. Depressed patients showed higher post-DST cortisol levels but similar responses to d-FEN compared with control subjects. Hormonal responses to d-FEN were not correlated with cortisol levels (basal or post-DST). Among the depressed patients, DST suppressors and DST nonsuppressors exhibited no significant difference in endocrine responses to d-FEN. However, patients with a history of suicide attempt, when compared with patients without such a history, showed lower hormonal responses to d-FEN but comparable basal and post-DST cortisol levels. Taken together these results suggest that, in depression, HPA axis hyperactivity is not responsible for the reduced 5-HT activity found in patients with a history of suicidal behavior.

Abstract
The efficacy and safety of two dosages of tolcapone were compared in a 12-week crossover trial involving 118 nonfluctuating patients with PD on a stable dose of levodopa (L-Dopa). At trial onset, all patients received open-label tolcapone 100 mg three times daily for 4 weeks. At week 4, 116 eligible patients entered an 8-week double-blind treatment period and were randomized to receive tolcapone three times daily at either 100 mg (group 1; n = 58) or 200 mg (group 2; n = 58) until week 8, followed by the alternative tolcapone dosage until week 12. Ratings included Unified Parkinson's Disease Rating Scale (UPDRS), Schwab & England, and patient diaries, assessed at baseline and at 4, 8, and 12 weeks. At week 4, the investigator's global assessment (IGA) of efficacy showed improvement in 76% of patients. The mean total daily L-Dopa dose and mean UPDRS scores for subscales II and III decreased significantly (p < 0.001). During the double-blind treatment period, IGA showed improvements at either or both dosages in 61% of patients; further changes in other efficacy variables were minimal and were similar with both tolcapone dosages. The most frequent adverse events were dopaminergic (nausea and dyskinesia); the most frequent nondopaminergic adverse event was diarrhea. The incidence of adverse events during double-blind treatment was slightly higher with tolcapone 200 mg three times daily (33%) than with tolcapone 100 mg three times daily (24%). The authors conclude that tolcapone dosages of 100 mg three times daily and 200 mg three times daily are well tolerated and equally effective in improving function in L-Dopa-treated nonfluctuating patients with PD.
