Options for Psychological and Medical Treatment of Gender Dysphoria For individuals seeking care for gender dysphoria treatment 247 buy clopidogrel online, a variety of therapeutic options can be considered. The number and type of interventions applied and the order in which these take place may differ from person to person. In children and adolescents, a rapid and dramatic developmental process (physical, psychological, and sexual) is involved and 10 World Professional Association for Transgender Health the Standards of Care 7th Version there is greater fuidity and variability in outcomes, particular in prepubertal children. Diferences between Children and Adolescents with Gender Dysphoria An important difference between gender dysphoric children and adolescents is in the proportion for whom dysphoria persists into adulthood. Boys in these studies were more likely to identify as gay in adulthood than as transgender (Green, 1987; Money & Russo, 1979; Zucker & Bradley, 1995; Zuger, 1984). Newer studies, also including girls, showed a 1227% persistence rate of gender dysphoria into adulthood (Drummond, Bradley, Peterson-Badali, & Zucker, 2008; Wallien & Cohen-Kettenis, 2008). In contrast, the persistence of gender dysphoria into adulthood appears to be much higher for adolescents. However, in a follow-up study of 70 adolescents who were diagnosed with gender dysphoria and given puberty suppressing hormones, all continued with the actual sex reassignment, beginning with feminizing/masculinizing hormone therapy (de Vries, Steensma, Doreleijers, & Cohen-Kettenis, 2010). Another difference between gender dysphoric children and adolescents is in the sex ratios for each age group. In clinically referred, gender dysphoric children under age 12, the male/female ratio ranges from 6:1 to 3:1 (Zucker, 2004). In clinically referred, gender dysphoric adolescents older than age 12, the male/female ratio is close to 1:1 (Cohen-Kettenis & Pfaffin, 2003). Additional research is needed to refne estimates of its prevalence and persistence in different populations worldwide. World Professional Association for Transgender Health 11 the Standards of Care 7th Version Phenomenology in Children Children as young as age two may show features that could indicate gender dysphoria. They may express a wish to be of the other sex and be unhappy about their physical sex characteristics and functions. In addition, they may prefer clothes, toys, and games that are commonly associated with the other sex and prefer playing with other-sex peers. There appears to be heterogeneity in these features: Some children demonstrate extremely gender nonconforming behavior and wishes, accompanied by persistent and severe discomfort with their primary sex characteristics. In other children, these characteristics are less intense or only partially present (Cohen-Kettenis et al. It is relatively common for gender dysphoric children to have co-existing internalizing disorders such as anxiety and depression (Cohen-Kettenis, Owen, Kaijser, Bradley, & Zucker, 2003; Wallien, Swaab, & Cohen-Kettenis, 2007; Zucker, Owen, Bradley, & Ameeriar, 2002). The prevalence of autistic spectrum disorders seems to be higher in clinically referred, gender dysphoric children than in the general population (de Vries, Noens, Cohen-Kettenis, van Berckelaer-Onnes, & Doreleijers, 2010). Phenomenology in Adolescents In most children, gender dysphoria will disappear before or early in puberty. However, in some children these feelings will intensify and body aversion will develop or increase as they become adolescents and their secondary sex characteristics develop (Cohen-Kettenis, 2001; Cohen-Kettenis & Pfaffin, 2003; Drummond et al. Data from one study suggest that more extreme gender nonconformity in childhood is associated with persistence of gender dysphoria into late adolescence and early adulthood (Wallien & CohenKettenis, 2008). Yet many adolescents and adults presenting with gender dysphoria do not report a history of childhood gender nonconforming behaviors (Docter, 1988; Landen, Walinder, & Lundstrom, 1998). Therefore, it may come as a surprise to others (parents, other family members, friends, and community members) when a youths gender dysphoria frst becomes evident in adolescence. Adolescents who experience their primary and/or secondary sex characteristics and their sex assigned at birth as inconsistent with their gender identity may be intensely distressed about it. Many, but not all, gender dysphoric adolescents have a strong wish for hormones and surgery. Increasing numbers of adolescents have already started living in their desired gender role upon entering high school (Cohen-Kettenis & Pfaffin, 2003). If such treatment is offered, the pubertal stage at which adolescents are allowed to start varies from Tanner stage 2 to stage 4 (Delemarre-van de Waal & Cohen-Kettenis, 2006; Zucker et al. The percentages of treated adolescents are likely infuenced by the organization of health care, insurance aspects, cultural differences, opinions of health professionals, and diagnostic procedures offered in different settings. Inexperienced clinicians may mistake indications of gender dysphoria for delusions. Phenomenologically, there is a qualitative difference between the presentation of gender dysphoria and the presentation of delusions or other psychotic symptoms. The vast majority of children and adolescents with gender dysphoria are not suffering from underlying severe psychiatric illness such as psychotic disorders (Steensma, Biemond, de Boer, & Cohen-Kettenis, published online ahead of print January 7, 2011). It is more common for adolescents with gender dysphoria to have co-existing internalizing disorders such as anxiety and depression, and/or externalizing disorders such as oppositional defant disorder (de Vries et al. As in children, there seems to be a higher prevalence of autistic spectrum disorders in clinically referred, gender dysphoric adolescents than in the general adolescent population (de Vries et al. Competency of Mental Health Professionals Working with Children or Adolescents with Gender Dysphoria the following are recommended minimum credentials for mental health professionals who assess, refer, and offer therapy to children and adolescents presenting with gender dysphoria: 1. Competent in diagnosing and treating the ordinary problems of children and adolescents. World Professional Association for Transgender Health 13 the Standards of Care 7th Version Roles of Mental Health Professionals Working with Children and Adolescents with Gender Dysphoria the roles of mental health professionals working with gender dysphoric children and adolescents may include the following: 1. Directly assess gender dysphoria in children and adolescents (see general guidelines for assessment, below). Provide family counseling and supportive psychotherapy to assist children and adolescents with exploring their gender identity, alleviating distress related to their gender dysphoria, and ameliorating any other psychosocial diffculties. Assess and treat any co-existing mental health concerns of children or adolescents (or refer to another mental health professional for treatment). Refer adolescents for additional physical interventions (such as puberty suppressing hormones) to alleviate gender dysphoria. The referral should include documentation of an assessment of gender dysphoria and mental health, the adolescents eligibility for physical interventions (outlined below), the mental health professionals relevant expertise, and any other information pertinent to the youths health and referral for specifc treatments. Educate and advocate on behalf of gender dysphoric children, adolescents, and their families in their community. This is particularly important in light of evidence that children and adolescents who do not conform to socially prescribed gender norms may experience harassment in school (Grossman, DAugelli, & Salter, 2006; Grossman, DAugelli, Howell, & Hubbard, 2006; Sausa, 2005), putting them at risk for social isolation, depression, and other negative sequelae (Nuttbrock et al. Provide children, youth, and their families with information and referral for peer support, such as support groups for parents of gender nonconforming and transgender children (Gold & MacNish, 2011; Pleak, 1999; Rosenberg, 2002). Assessment and psychosocial interventions for children and adolescents are often provided within a multi-disciplinary gender identity specialty service. If such a multidisciplinary service is not available, a mental health professional should provide consultation and liaison arrangements with a pediatric endocrinologist for the purpose of assessment, education, and involvement in any decisions about physical interventions. Mental health professionals should not dismiss or express a negative attitude towards nonconforming gender identities or indications of gender dysphoria. Rather, they should acknowledge the presenting concerns of children, adolescents, and their families; offer a thorough assessment for gender dysphoria and any co-existing mental health concerns; and educate clients and their families about therapeutic options, if needed. Acceptance and removal of secrecy can bring considerable relief to gender dysphoric children/adolescents and their families. Assessment of gender dysphoria and mental health should explore the nature and characteristics of a childs or adolescents gender identity. Assessment should include an evaluation of the strengths and weaknesses of family functioning. Emotional and behavioral problems are relatively common, and unresolved issues in a childs or youths environment may be present (de Vries, Doreleijers, Steensma, & Cohen-Kettenis, 2011; Di Ceglie & Thummel, 2006; Wallien et al. For adolescents, the assessment phase should also be used to inform youth and their families about the possibilities and limitations of different treatments. The way that adolescents respond to information about the reality of sex reassignment can be diagnostically informative. Correct information may alter a youths desire for certain treatment, if the desire was based on unrealistic expectations of its possibilities. Psychological and Social Interventions for Children and Adolescents When supporting and treating children and adolescents with gender dysphoria, health professionals should broadly conform to the following guidelines: 1. Pathophysiology of Parkinsons disease rigidity: role of corticospinal motor projections symptoms 1 week after conception cheap 75mg clopidogrel with visa. Neurophysiology of Parkinsons disease symptoms quitting tobacco purchase clopidogrel line, levodopa-induced dyskinesias world medicine cheap clopidogrel online american express, dystonia medicine app order clopidogrel without a prescription, Huntingtons disease and myoclonus. Relationship between electromyographic activity and clinically assessed rigidity studied at the wrist joint in Parkinsons disease. Risus sardonicus may also occur in the context of dystonia, more usually symptomatic (secondary) than idiopathic (primary) dystonia. Cross References Parkinsonism; Wheelchair sign Rogers Sign Rogers sign, or the numb chin syndrome, is an isolated neuropathy affecting the mental branch of the mandibular division of the trigeminal (V) nerve, causing pain, swelling, and numbness of the lower lip, chin, and mucous membrane inside the lip. Hypoaesthesia involving the cheek, upper lip, upper incisors, and gingiva, due to involvement of the infraorbital portion of the maxillary division of the trigeminal nerve (numb cheek syndrome), is also often an ominous sign, resulting from recurrence of squamous cell carcinoma of the face inltrating the nerve. Le signe du mentonnier (parasthesie et anesthesie unilaterale) revelateur dun processus neoplasique metastatique. Cross References Parkinsonism; Wartenbergs swing test Rombergism, Rombergs Sign Rombergs sign is adjudged present (or positive) when there is a dramatic increase in unsteadiness, sometimes with falls, after eye closure in a patient standing comfortably (static Rombergs test). Before asking the patient to close his or her eyes, it is advisable to position ones arms in such a way as to be able to catch the patient should they begin to fall. A modest increase in sway on closing the eyes may be seen in normal subjects and patients with cerebellar ataxia, frontal lobe ataxia, and vestibular disorders (towards the side of the involved ear); on occasion these too may produce an increase in sway sufficient to cause falls. Large amplitude sway without falling, due to the patient clutching hold of the physician, has been labelled psychogenic Rombergs sign, an indicator of functional stance impairment. Cross References Ataxia; Functional weakness and sensory disturbance; Proprioception; Tandem walking Roos Test Roos test, or the elevated arm stress test, may be helpful in the diagnosis of vascular thoracic outlet syndrome, along with Adsons test. Development of numbness, pain, and paraesthesia, along with pallor of the hand, supports the diagnosis of thoracic outlet syndrome. Its presence in adults is indicative of diffuse premotor frontal disease, this being a primitive reex or frontal release sign. These movements may be performed voluntarily (tested clinically by asking the patient to Look to your left, keeping your head still, etc. A number of parameters may be observed, including latency of saccade onset, saccadic amplitude, and saccadic velocity. Of these, saccadic velocity is the most important in terms of localization value, since it depends on burst neurones in the brainstem (paramedian pontine reticular formation for horizontal saccades, rostral interstitial nucleus of the medial longitudinal fasciculus for vertical saccades). Latency involves cortical and basal ganglia circuits; antisaccades involve frontal lobe structures; and amplitude involves basal ganglia and cerebellar circuits (saccadic hypometria, with a subsequent correctional saccade, may be seen in extrapyramidal disorders such as Parkinsons disease; saccadic hypermetria or overshoot may be seen in cerebellar disorders). In Alzheimers disease, patients may make reex saccades towards a target in an antisaccadic task (visual grasp reex). Assessment of saccadic velocity may be of particular diagnostic use in parkinsonian syndromes. In progressive supranuclear palsy slowing of vertical saccades is an early sign (suggesting brainstem involvement; horizontal saccades may be affected later), whereas vertical saccades are affected late (if at all) in corticobasal degeneration, in which condition increased saccade latency is the more typical nding, perhaps reective of cortical involvement. Several types of saccadic intrusion are described, including ocular utter, opsoclonus, and square wave jerks. Saccadic (cogwheel) pursuit is normal in infants and may be a non-specic nding in adults; however, it may be seen in Huntingtons disease. This is a late, unusual, but diagnostic feature of a spinal cord lesion, usually an intrinsic (intramedullary) lesion but sometimes an extramedullary compression. Spastic paraparesis below the level of the lesion due to corticospinal tract involvement is invariably present by this stage of sacral sparing. Sacral sparing is explained by the lamination of bres within the spinothalamic tract: ventrolateral bres (of sacral origin), the most external bres, are involved later than the dorsomedial bres (of cervical and thoracic origin) by an expanding central intramedullary lesion. Although sacral sparing is rare, sacral sensation should always be checked in any patient with a spastic paraparesis. The outstanding ability may be feats of memory (recalling names), calculation (especially calendar calculation), music, or artistic skills, often in the context of autism or pervasive developmental disorder. Obsolete classication of such abilities as superlative technical skill, hypermnesia, calculating idiots, and calendar artists has been superseded by interest in how the disparities between these and general intellectual abilities come about and whether this is some form of release phenomenon. Occasionally, skills 320 Scoliosis S such as artistic ability may emerge in the context of neurodegenerative disease (Alzheimers disease, frontotemporal lobar degeneration). Scanning speech was originally considered a feature of cerebellar disease in multiple sclerosis (after Charcot), and the term is often used with this implication. However, cerebellar disease typically produces an ataxic dysarthria (variable intonation, interruption between syllables, explosive speech) which is somewhat different from scanning speech. Scanning speech correlates with midbrain lesions, often after recovery from prolonged coma. Cross References Delusion; Neologism; Paraphasia; Wernickes aphasia Schwabach Test In the Schwabach test, a vibrating tuning fork is held against the patients mastoid process, as in Rinnes test, until it is no longer audible. The examiner then places the tuning fork over his/her own mastoid, hence comparing bone conduction with that of the patient. If still audible to the examiner (presumed to have normal hearing), a sensorineural hearing loss is suspected, whereas in conductive hearing loss the test is normal. Mapping of the defect may be performed manually, by confrontation testing, or using an automated system. In addition to the peripheral eld, the central eld should also be tested, with the target object moved around the xation point. A central scotoma may be picked up in this way or a more complex defect such as a centrocaecal scotoma in which both the macula and the blind spot are involved. Infarction of the occipital pole will produce a central visual loss, as will optic nerve inammation. Scotomata may be absolute (no perception of form or light) or relative (preservation of form, loss of colour). A scotoma may be physiological, as in the blind spot or angioscotoma, or pathological, reecting disease anywhere along the visual pathway from retina and choroid to visual cortex.

It has been claimed as a reliable test of posterior column function of the spinal cord. Errors in this test correlate with central conduction times and vibration perception threshold. The utility of testing tactile perception of direction of scratch as a sensitive clinical sign of posterior column dysfunction in spinal cord disorders. A reappraisal of direction of scratch test: using somatosensory evoked potentials and vibration perception. Cross References Proprioception; Vibration Seborrhoea Seborrhoea is a greasiness of the skin which may occur in extrapyramidal disorders, particularly Parkinsons disease. Seizure morphology may be helpful in establishing aetiology and/or focus of onset. Partial: simple (no impairment of consciousness), for example, jerking of one arm, which may spread sequentially to other body parts (Jacksonian march); or complex, in which there is impairment or loss of consciousness: may be associated with specic aura (olfactory, deja vu, jamais vu) and/or automatisms (motor. Otherwise, as for idiopathic generalized epilepsies, various antiepileptic medications are available. Best treated with psychological approaches or drug treatment of underlying affective disorders; antiepileptic medications are best avoided. The differentiation of epileptic from non-epileptic seizures may be difficult; it is sometimes helpful to see a video recording of the attacks or to undertake in-patient video-telemetry. This pattern is highly suggestive of a foramen magnum lesion, usually a tumour but sometimes demyelination or other intrinsic inammatory disorder, sequentially affecting the lamination of corticospinal bres in the medullary pyramids. Cross References Hemiparesis; Paresis; Quadriparesis, Quadriplegia Setting Sun Sign the setting sun sign, or sunset sign, consists of tonic downward deviation of the eyes with retraction of the upper eyelids exposing the sclera. Setting sun sign is a sign of dorsal midbrain compression in children with untreated hydrocephalus.
Primary care centres are limited in their ability to adequately diagnose and treat certain neurological disorders treatment kidney infection buy cheap clopidogrel 75mg on line. For the management of severe cases and patients requiring access to diagnostic and technological expertise treatment neutropenia order clopidogrel with mastercard, a secondary level of care is necessary treatments yeast infections pregnant purchase genuine clopidogrel on line. A number of neurological services may be offered in district or regional hospitals that form part of the general health system medicine world nashua nh purchase genuine clopidogrel online. Common facilities include inpatient beds in general medicine, specialist beds, emergency departments and outpatient clinics. These services require adequate numbers of general as well as specialist professionals who can also provide supervision and training in neurology to primary care staff. In some countries, there are also other public or private facilities offering various types of neurological services in inpatient wards and outpatient clinics. These facilities are not expected to deliver primary neurological care but act as secondary and tertiary referral services. They also serve as facilities for clinical research, collection of epidemiological data, and the creation and distribution of health educational materials. Neurological specialist services require a large complement of trained specialist staff. Shortages of such staff are a serious problem in low income countries, as are the lack of nancial resources and infrastructure. Even within countries, signicant geographical disparities usually exist between regions. Little concerted effort has been made to use primary care as the principal vehicle of delivery of neurological services. Some countries have good examples of intersectoral collaboration between nongovernmental organizations, academic institutions, public sector health services and informal community-based health services. At present, such activities are limited to small populations in urban areas; most rural populations have no access to such services. Even in developed countries, more emphasis is placed on providing specialist services than on approaches to integrate neurological services into primary care. Such disorders are better managed by services that adopt a continuing care approach, emphasizing the long-term nature of these neurological disorders and the need for ongoing care. The emphasis is on an integrated system of service delivery that attempts to respond to the needs of people with neurological disorders. Integrated and coordinated systems of service delivery need to be developed where services based in primary, secondary and tertiary care complement each other. In order to address the needs of persons with neurological disorders for health care and social support, a clear referral and linkage system needs to be in place. The key principles for organizing such services include accessibility, comprehensiveness, coordination and continuity of care, effectiveness, and equity within the local social, economic and cultural contexts. Management of the disability is aimed at cure or the individuals adjustment and behaviour change. The social model of disability sees the issue mainly as a socially created problem and a matter related to the full integration of individuals into society. According to the social model, disability is not an attribute of the individual, but rather a complex collection of conditions, many of which are created by the social environment: the approach to disability requires social action and is a responsibility of society. Rehabilitation is one of the key components of the primary health-care strategy, along with promotion, prevention and treatment. While promotion and prevention primarily target risk factors of disease and public health principles and neurological disorders 17 treatment targets ill-health, rehabilitation targets human functioning. As with other key health strategies, it is of varying importance and is relevant to all other medical specialities and health professions. Though rooted in the health sector, rehabilitation is also relevant to other sectors including education, labour and social affairs. For example, building of ramps and other facilities to improve access by disabled people falls beyond the purview of the health sector but is nevertheless very important for the comprehensive management of a person with a disability. As a health-care strategy, rehabilitation aims to enable people who experience or are at risk of disability to achieve optimal functioning, autonomy and self-determination in the interaction with the larger physical, social and economic environment. It is based on the integrative model of human functioning, disability and health, which understands human functioning and disability both as an experience in relation to health conditions and impairments and as a result of interaction with the environment. Rehabilitation involves a coordinated and iterative problem-solving process along the continuum of care from the acute hospital to the community. It is based on four key approaches integrating a wide spectrum of interventions: 1) biomedical and engineering approaches; 2) approaches that build on and strengthen the resources of the person; 3) approaches that provide for a facilitating environment; and 4) approaches that provide guidance across services, sectors and payers. Specic rehabilitation interventions include those related to physical medicine, pharmacology and nutrition, psychology and behaviour, education and counselling, occupational and vocational advice, social and supportive services, architecture and engineering and other interventions. Health is a fundamental right, and rehabilitation is a powerful tool to provide personal empowerment. Rehabilitation strategy Because of the complexity of rehabilitation based on the above-mentioned integrative model, rehabilitation services and interventions applying the rehabilitation strategy need to be coordinated along the continuum of care across specialized and non-specialized services, sectors and payers. The rst refers to the guidance along the continuum of care and the second to the provision of a specic service. The assignment step refers to the assignment to a service and an intervention programme. The Evaluation Assignment evaluation step refers to service and the achievement of the intervention goal. The assignment step refers to the assignment of health professionals and interventions to the intervention targets. The intervention step refers to the specication of the intervention techniques, the denition of indicator measures to follow the progress of the intervention, and the denition of target values to be achieved within a 18 Neurological disorders: public health challenges predetermined time period. It also includes the decision regarding the need for another intervention cycle based on a reassessment. Rehabilitation of neurological disorders Rehabilitation should start as soon as possible after the diagnosis of a neurological disorder or condition and should focus on the community rehabilitation perspective. The type and provision of services is largely dependent on the individual health-care system. Therefore no generally agreed principles currently exist regarding the provision of rehabilitation and related services. Rehabilitation is often exclusively associated with well-established and coordinated multidisciplinary efforts by specialized rehabilitation services. While availability and access to these specialized inpatient or outpatient services are at the core of successful rehabilitation, a need also exists for rehabilitation service provision, from the acute settings through the district hospital and the community, often by health professionals not specialized in rehabilitation but working closely with the rehabilitation professionals. It is important to recognize that rehabilitation efforts in the community can be delivered by professionals outside the health sector, ideally in collaboration with rehabilitation professionals. Rehabilitation services are limited or nonexistent in many developing countries for people with disabilities attributable to neurological disorders or other causes. This means that many individuals with disabilities will depend totally on other people, usually family members, for help with daily activities, and this situation enhances poverty. Impoverished communities throughout the world are affected by a disproportionate number of disabilities and, in turn, people with disabilities become more vulnerable to poverty because of a lack of access to , or availability of, health care, social care and rehabilitation services. When rehabilitation services are available, the lack of human resources limits considerably the transfer of knowledge from specialized centres to district and community settings. The strategy of community-based rehabilitation has been implemented in many low income countries around the world and has successfully inuenced the quality of life and participation of persons with disabilities in societies where it is in practice. The philosophy of rehabilitation emphasizes patient education and self-management and is well suited for a number of neurological conditions. The basis for successful neurorehabilitation is the in-depth understanding and sound measurement of functioning and the application of effective interventions, intervention programmes and services. A wide range of rehabilitation interventions, intervention programmes and services has been shown to contribute effectively to the optimal functioning of people with neurological conditions. Effective neurorehabilitation is based on the involvement of expert and multidisciplinary assessment, realistic and goal-oriented programmes, and evaluation of the impact on the patients rehabilitation achievements; evaluation using scientically sound and clinically appropriate outBox 1.

To help prepare you for the exam symptoms xanax buy clopidogrel 75mg fast delivery, Chapter 15 presents a group of testing tips and Chapter 16 focuses on how to answer the free-response questions xerostomia medications side effects discount 75mg clopidogrel with amex. We have included a discussion of how best to approach the essays and also provide a number of examples of the kinds of essay questions likely to appear on the exam medications 7 rights order online clopidogrel. We also include model essay answers to give you an idea of what the readers of the exam are looking for medicine 014 75 mg clopidogrel with amex. Finally, the book includes an index that will be helpful to you anytime you come across a term or person you know is important, but do not remember. This eBook contains hundreds of hyperlinks that will help you navigate through the content of the book, bring you to helpful resources, and allow you to click between all questions and answers. They are listed in the table below, along with the chapter(s) in which you can find more information about them and their major contributions to the field. The multiple-choice portion of the exam contains 100 five-choice (A to E) questions. Overall, the questions in the latter part of the exam are a little more difficult than the early ones. Since there is no guessing penalty, you should try to answer every multiple-choice question on the exam. The free-response section of the test consists of two questions, and you must answer them both. Some students find writing two full essays in such a short amount of time to be difficult. Chapter 16 includes some helpful suggestions for tackling this section of the exam. Your score (ranging from 1 to 5) on the exam will take into account your performance on both the multiple-choice and free-response sections, with the multiple-choice section counting for twice as much. This means that two-thirds of your score depends on your performance on the multiple-choice questions, and the other one-third of your score is based on the quality of your essays. Each year, the exact breakdown of the percentage of people who earn each score differs.

The tube contains approximately 3 mL of gel and was flushed with water, which results in a fast bolus dose administration of 60/15 mg of levodopa/carbidopa and 60/60/15 mg of levodopa/entacapone/carbidopa. As night-time medication, patients were allowed to take levodopa/carbidopa immediate release oral tablets after infusion stop and up until three hours prior to infusion start. During the study, low-protein meals were served at hours 1, 4, 7, 10 and 13 after infusion start. A blood sample was collected within 5 min after flushing the tube and thereafter half-hourly from 14. Levodopa/carbidopa microtablets in healthy subjects Two studies had been previously performed with levodopa/carbidopa microtablets (Study 1 and Study 2, Table 1). Study 1 was a single-center, open-label, single dose study where 18 healthy volunteers received 100/25 mg of levodopa-carbidopa 40 microtablets. Blood samples were obtained once prior to dosing, every 10 minutes during the first hour after dose administration, every 20 minutes between hour 1 and 2, half-hourly between hour 2 and 3, hourly between hours 3 and 6, and then at 8, 10, 12 and 24 hours. Study 1 was included in the development of a population pharmacokinetic model for levodopa/carbidopa microtablets. The second study was a single-center, open-label, multiple dose study in116 cluding 10 healthy subjects (Study 2). The first dose was dispersed in 100 mL of water, and after intake an additional 100 mL of water was given. Blood samples were collected 5 minutes prior to each dose administration and at 20, 40, 60 and 90 minutes after dose intake. The last blood sample was taken at 810 minutes from the first dose administration. Study 2 was used for external validation of the levodopa microtablet population pharmacokinetic model, i. Levodopa/carbidopa microtablets All samples were analyzed at the Department of Pharmacology, University of Gothenburg, Sweden. After thawing and protein precipitation, the plasma concentrations of levodopa and carbidopa were determined (Table 2). Measurements of entacapone were missing for the first 5 patients due to degradation of entacapone by the stabilizer (sodium metabisulfite), which the blood collection tubes were primed with. Following this discovery, blood samples were collected in two different blood collection tubes, one with stabilizer, and one without. After thawing, and protein precipitation, the plasma concentrations of levodopa and carbidopa were determined (Table 2). Pharmacokinetic analysis Non-compartmental pharmacokinetic assessment All analyses were performed in R 3. The blood samples that were not drawn on the exact time point were approximated to the pre-specified times for the statistical analysis. The measured concentration at time 0 was subtracted from the rest of the measurements that were then divided with the individual administered dose of each compound. At least three descending measurements were required for the cal32 culation of t. The Welch two-sample t-test was used to compare the calcu-40 lated parameters from patients with values from healthy subjects. The inter-individual variability was included assuming a lognormal or normal (absorption related parameters) distribution of structural model parameters. The residual error models evaluated were additive, proportional, or combined additive and proportional error models. Levodopa/carbidopa microtablets the models for levodopa and carbidopa from microtablet administration were developed separately, and then combined for the covariate analysis. The patient population had a higher than expected plasma concentration at study start (mean 0. The plasma concentration prior to dose administration was estimated (with inter-individual variability), and assumed to be eliminated at the same rate as the individually estimated slopes of levodopa and carbidopa. For a description of the pharmacokinetics, including the double-peaks, several models were investigated; parallel absorption compartments where fractions of the total dose administered are assumed to be fractionated into two separate dosing compartments (fraction was estimated on the logit transformed scale to constrain the parameter between zero and one), with transit compartments or lag-times separately estimated, and with and without the inclusion of a mixture model; an empirical model where two gastric emp33 tying rates are estimated and; a semi-mechanistic model where an effect compartment links the plasma concentration of levodopa which acts as a feedback mechanism on the rate of gastric emptying. Because both levodopa and carbidopa were measured from the same blood sample and their residual error could be correlated, a part of the residual error was modeled as being shared between them. Because few blood samples were collected in relation to the oral treatment, the information was insufficient to allow for estimation of oral levodopa absorption related parameters. The absorption model for the oral treatment was described according to 128 a previously published model: one transit compartment between the depot 1 and central compartment, a single transfer rate constant fixed to 2. For illustration of a new dosing scheme on a population level, 1000 replicates of the dataset were simulated based on the study population, with altered doses. Initially, a graphically analysis was performed on all parameter-covariate relationships, by plotting empirical Bayes estimates versus covariates. The data split was made on study association, to preserve the relative proportions in the cross-validation datasets. It is a penalized estimation method where the covariates are stand130 ardized to a mean of zero and a variance of one. The covariates are included according to a linear covariate-parameter correlation and the selection of covariates is carried out based on the tuning parameter (t-value). The estimated regression coefficients are restricted based on the t-value which restricts the model size. The sum of the covariate coefficients has to be smaller than the t-value, which is estimated with a five-fold cross-validation. One advantage of the method is that all covariate-parameter relationships are tested simultaneously. In the microtablet trial (Paper I) the motor function test was done in repeated test cycles, once before the study dose administration and then repeatedly every 20 minutes until 111 minutes, and thereafter every 30 minutes until 321 minutes (time of the last test) or until the patient could no longer remain 36 without medication. Each test cycle was video recorded for blinded (with respect to time) assessment by three movement disorder specialists. A computer program was used to randomize the video sequences to ensure that the rating was blinded. The items included were; finger tapping (item 23), rapid alternating movements of hands (item 25), tapping the heel (item 26, only rated by two of the raters), rising from chair with arms held across the chest (item 27), gait (item 29) and bradykinesia (item 31) (Figure 5). The assessment of patient motor function was done at the same time points as the pharmacokinetic sampling. All patients with ongoing treatment, and four of the patients who had discontinued treatment, answered the survey. The two patients that had discontinued the treatment and did not answer the questionnaire were judged by their physician to be too cognitively impaired to do so. Levodopa/entacapone/carbidopa intestinal infusion Eleven patients were included in and completed the infusion study (Table 4). Pharmacokinetics Non-compartmental analysis of levodopa/carbidopa microtablets the patients had a higher than expected plasma concentration prior to dose administration, and therefore the non-compartmental analysis was conducted on data adjusted for the measured concentration prior to dose administration. The baseline and dose adjusted levodopa maximum concentration (Cmax/dose), was found to be higher for patients (p=0. Four patients were excluded from the comparison of systemic exposure and half-life estimation due to early drop-out. One patient was excluded due to an extremely high concentration prior to dose administration. The carbidopa half-life was found to be longer for patients, compared to the healthy volunteers (p=0.

The final model parameter estimates, together with corresponding uncertainties are listed in Table 6. Double-peak profiles, observed in both healthy subjects and patients, were adequately described with parallel absorption compartments, and included five and six transit compartments for levodopa and three and 10 transit compartments for carbidopa (Individual plots, for illustration purpose, Figure 6).
