All subjects received weekly group therapy emphasizing motivational enhancement symptoms checklist purchase citalopram 20 mg on line, relapse prevention symptoms iron deficiency purchase discount citalopram on-line, and social skills training medications side effects purchase citalopram discount. Trial endpoint cessa tion rates (confirmed by a carbon monoxide level <10 ppm) were 50% (8 of 16) in the bu propion group and 12. Positive symptoms of schizophrenia were not affected, but negative symptom scores were reduced by about 15% in the bupropion group. In addition, treatment with a second versus a first-generation antipsy chotic medication strongly predicted success in smoking cessation in patients with schizo phrenia. The results from these preliminary placebo-controlled trials of bupropion suggest that smoking reduction and cessation are possible in patients with schizophrenia, exacerbation of psychotic symptoms is unlikely, and negative symptoms of schizophrenia may be reduced. With endpoint cessation rates of 11%�50%, bupropion may be more effective at higher doses (300 vs. In addition, the use of bupropion is not recommended in individuals with a past or particularly a current diagnosis of an eating disorder because one study found an increased risk of generalized tonic clonic (grand mal) seizures in bupropion-treated patients with bulimia (1591. Bupropion is started 7 days before the target quit date at 150 mg/day and, after 4�5 days, the dose is increased to 150 mg b. Currently there are few data as to which subgroups of smokers may benefit most for treatment with bupropion, although Treatment of Patients With Substance Use Disorders 141 Copyright 2010, American Psychiatric Association. Some evidence suggests that its benefits persist for up to a year of treatment (895) and that its efficacy can be augmented by concomi tant use of the nicotine patch (455); however, data on adding psychosocial therapies to nortrip tyline treatment are mixed (456, 895, 1579. Nortriptylines mechanism of action in treating nicotine dependence is unclear, although the medication does block reuptake of norepinephrine and serotonin and may have indirect effects on dopamine (816. In addition, its mechanism in nicotine dependence may be distinct from its mechanism in treating depression, because its efficacy in smoking cessation is unrelated to the presence or absence of depressive symptoms or major depressive disorder (456, 795, 815, 816. Side effects of nortriptyline are frequent (455, 815, 816) and include anticholinergic effects (e. The toxicity of nortriptyline in overdose amounts also needs to be taken into consideration when prescribing this medication. Because of its suggested efficacy for alcohol and opioid withdrawal, it was tried with nicotine withdrawal as well (749, 1593. The most common side effects of clonidine treatment are dry mouth, se dation, and constipation (818, 819, 1594. Postural hypotension, rebound hypertension, and depression are rare when clonidine is used for smoking cessation treatment (1594. In several small trials (820, 821), it was shown to result in an initial increase but a subsequent decrease in cig arette use. It has been postulated that naltrexone, the long-acting oral form of the short-acting intravenous opioid antagonist naloxone, would be useful in treating nicotine dependence be cause the performance-enhancing and other positive effects of nicotine may be opioid medi ated (1596. Although one preliminary study showed benefits of naltrexone in combination with nicotine patch therapy (1597), naltrexone did not appear to decrease smoking in other studies (603, 822) and may even have increased smoking in some individuals (749, 1598. Thus, there is little evidence that these diverse pharmacotherapies are useful for smoking cessation. In addition to bupropion and nortriptyline, other antidepressive agents have been studied in nicotine-dependent patients. Although possible benefits have been found for the monoamine oxidase A inhibitor moclobemide (1607) and the monoamine oxidase B inhibitor selegiline hydrochloride (1608) for smoking cessation, larger trials of these agents are warranted. At the present time there is no evidence that other antidepressants are efficacious in treating nicotine dependence (795. The efficacy of auricular acupuncture has been supported by some (786) but not other (1609) studies. The results of two more recent controlled studies (785, 1610) suggest that active versus sham acupuncture can lead to short and long-term reduction in cigarette smoking but not smoking cessation. In addition, a meta analysis of multiple other smaller studies of acupuncture has found no evidence for acupunc ture efficacy in smoking cessation (788. In accordance with these results, acupuncture cannot be recommended as a treatment for smoking cessation. Other somatic treatments that have been proposed include black pepper extracts (1611), capsaicin (1612), denicotinized tobacco (1613�1615), cigarette flavorings (1616), regenerated (denicotinized) smoke (1617), and citric acid inhaler (1618, 1619), all of which decrease ciga rette craving or withdrawal symptoms or provide a substitute for the satisfaction from cigarettes in laboratory tests. However, none of these modalities have been sufficiently studied to recom mend their use.
No major opinion apparently has addressed whether the exclusion of laws of nature from patent-eligibility is constitutionally mandated medications qid order generic citalopram, although this may be the case medications or therapy buy 20mg citalopram fast delivery, because patents on laws of nature would not serve to promote the progress of useful arts cancer treatment 60 minutes citalopram 40 mg cheap. The isolation and purification exception to the general unpatentability of products of nature. Oysters and oligonucelotides: concerns and proposals for patenting research tools. Purification and isolation here refer not to absolute purity, but to the general absence of other large molecules and biological substances. Supreme Court considered a different inquiry: whether a living thing that did not occur naturally was patentable. A case that was closely watched by the biotechnology community, Charkrabarty concerned the patentability of a bacterium that had 196 been genetically altered by introducing plasmids that enabled it to degrade oil. The Supreme Court held that the bacterium qualified as a patentable manufacture or composition of matter because it was �a new bacterium with markedly different characteristics from any found in 197 nature and one having the potential for significant utility. No case, however, has squarely considered the question of whether 199 isolated, purified nucleic acid molecules are patentable subject matter. Conley and Makowski argue that the focus of the patentability inquiry, as established in Parke-Davis and Charkrabarty, is not on purification per se, but on whether an invention derived from nature differs �in some substantial and material 194 Parke-Davis & Co. At least some cases before Parke-Davis that considered whether claimed inventions derived from nature were patentable found that they were not patentable�see, for example, American Wood-Paper Co. Even some cases after Parke-Davis found such inventions not to be patentable�see, for example, General Electric Co. Different perspectives on the evolution of �products of nature jurisprudence can be found in Gipstein, op. Back to the future: rethinking the product of nature doctrine as a barrier to biotechnology inventions (Part I. Journal of the Patent & Trademark Office Society 85:371-398; and L Andrews and J Paradise. Paper presented at the Conference on Living Properties: Making Knowledge and Controlling Ownership in the History of Biology. District Court, Southern District of New York, the plaintiffs argue that patents on isolated nucleic acid molecules and association patent claims violate �long established principles 206 that prohibit the patenting of laws of nature, products of nature, and abstract ideas. If the defendants prevail, the Committees recommendation will still be relevant because gene patents and associations will remain enforceable. But even if the plaintiffs prevail, the decision would not lead to the automatic 208 invalidation of all existing patents on genes and associations. Conley and Makowskis statement that the invention must have material differences over the product of nature is simply a way of rephrasing the Parke-Davis requirement that the invention differ in kind from the product of nature. It also challenges patents that claim methods of associating a genotype with a phenotype. District Court for the Southern District of New York held in a written decision issued on March 29, 2010, that the claims-in-suit were invalid for claiming unpatentable subject matter. Recent Case Law Relevant to Association Patent Claims During its 2010 term, the U. Before reviewing this case, this section provides some background on these patents and the controversy they have provoked. As noted in the Introduction, novel, useful, and nonobvious processes are eligible for patents. Relying on this ability to patent processes or methods, researchers who have discovered associations between particular gene variants and disease have obtained patent claims upon processes involving simply associating a genotype with a phenotype. Critics of the patenting of such associations argue that process claims of this nature should not be patent-eligible because they involve unpatentable fundamental laws of nature�namely, the relationship or association between a particular genetic sequence and a disease. Furthermore, it 209 can be argued that such processes involve mental steps that are not subject to protection. Supreme Court precedent, the Federal Circuit first recognized that processes that involve a specific application of an abstract idea or natural law are patent-eligible, even though abstract ideas and natural laws themselves are not 210 patentable. The Federal Circuit then elaborated that a process is limited to a specific application of an abstract idea or natural law (and thus patentable) if (1) it is tied to a particular 211 machine or apparatus or (2) it transforms a particular article into a different state or thing. The patented process in question in Bilski was not a process for simply associating a genotype 212 with a phenotype, but �a method of hedging risk in the field of commodities trading. The answer will depend on how patent examiners and courts interpret the precise meaning of �machine and �transformation.
Maternal and neonatal transport programs are typically considered separately because they each have particular characteristics medicine hat buy discount citalopram 40 mg on-line, requirements symptoms rotator cuff injury citalopram 10mg online, and are generally overseen by their respective specialists treatment syphilis buy citalopram overnight. Maternal Transport Maternal transport refers to the transport of a pregnant woman during the antepartum period or intrapartum period for special care of the woman, the neonate, or both. Occasionally, the same system is used to transport a postpar tum woman so that the mother can either be with her baby or receive a higher level of care for severe postpartum complications. Depending on the severity of the maternal illness, a team from the receiving hospital may go to the referring hospital to pick up the patient, or the patient may be sent by one-way ambu lance from the referring hospital to the receiving hospital. All attempts should be made to ensure that women and infants at high risk receive care in a facility that provides the required level of specialized obstetric and newborn care. Formal transfer agreements should be in place that clearly outline the responsibilities of each facility. Neonatal Transport the interhospital transfer of a newborn infant who requires specialized or intensive care generally proceeds according to one of the following approaches: � A team is sent from one hospital, often a regional center, to the referring hospital to evaluate and stabilize the infant at the referring hospital and then transfer the infant to the teams hospital. Maternal and Neonatal Interhospital Transfer 79 � A team is sent from one hospital to the referring hospital to evaluate and stabilize the infant and then transfer the infant to a third hospital. Such a transfer may be necessary because of bed constraints or the need for spe cialized care available only at the third hospital. Transport Program Components and Responsibilities Components To ensure optimal care of patients at high risk, the following components should be part of a regional referral program: � Formal transfer plans for mothers and infants with receiving hospitals that are established by facilities that provide lower levels of care � A method of risk identification and assessment of problems that are expected to benefit from consultation and transport � Assessment of the perinatal capabilities and determination of conditions necessitating consultation, referral, transfer, and return transfer of each participating hospital � Resource management to maximize efficiency, effectiveness, and safety � Adequate financial and personnel support � A reliable, accurate, and comprehensive communication system between participating hospitals and transport teams � Determination of responsibility for each of these functions An interhospital transport program should provide 24-hour service. It should include a receiving or program center responsible for ensuring that patients at high risk receive the appropriate level of care, a dispatching unit to coordinate 80 Guidelines for Perinatal Care the transport of patients between facilities, an appropriately equipped transport vehicle, and a specialized transport team. The program also should have a sys tem for providing a continuum of care by various health care providers, includ ing the personnel and equipment required for the level of care needed, as well as outreach education and program evaluation. Responsibilities Each of the functional components of an interhospital transport program has specific responsibilities. If the transport is done by the referring hospital, the referring physician and hospital retain responsibility until the transport team arrives with the patient at the receiving hospital. If the transport team is sent by the receiving hospital, the receiving physician or designee assumes responsibility for patient care from the time the patient leaves the referring hospital. It should be emphasized that during the preparation for transport by the transport team, the referring physician and hospital retain responsibility for the patient unless there have been other prior agreements. Transport services should work with their referring hospital to delineate clearly the primary medical responsibility for the patient when the patient is still within the referring hospital but is being cared for by the transport team. Regardless of the site of origin of the transport team, qualified staff should accompany the patient to the receiving hospital. Medical�Legal Aspects Many legal details of perinatal transport are not well defined and are subject to interpretation. In addition, many transport teams provide service in more than one state and therefore must comply with the laws of the state in which they are practicing and cannot be guided solely by their home state or area. Legal consult should be sought when developing a service to ensure compatibility with existing laws, and periodic review is encouraged to maintain compliance with laws and regulations. It is clear that all involved parties (eg, the referring hospital and personnel, the receiving hospital and personnel, and the transpor tation carriers or corporations) assume a number of responsibilities for which they are accountable: � Each transport system must comply with the standards and regulations set forth by local, state, and federal agencies. The completed consent form should be signed by the patient or Maternal and Neonatal Interhospital Transfer 81 parent or guardian and witnessed; a copy should be placed in the patients medical record. If the neonatal patient requires an emergency procedure before the parents arrival at the receiving facility, the informed consent for this procedure should be obtained before departure from the referring facility if this action will not adversely delay the transport. The professional qualifications and actions of the transport team are the responsibility of the institution that employs the team. Director the director of the transport programs (maternal or neonatal) should be either a subspecialist in maternal�fetal medicine or neonatology, respectively, or, in selected cases, an obstetrician�gynecologist or pediatrician, respectively, with special expertise in these subspecialty areas. As noted previously, typically the programs are organized and directed separately. The program directors respon sibilities include the following: � Training and supervising staff � Ensuring appropriate review of all transport records � Developing and implementing protocols for patient care � Developing and maintaining standardized patient records and a database to track the program � Establishing a program for performance quality 82 Guidelines for Perinatal Care � Identifying trends and effecting improvements in the transport system by regularly reviewing the following elements: � Reviewing operational aspects of the program, such as response times, effectiveness of communications, and equipment issues � Reviewing evaluation forms completed by the referring and receiving hospitals soon after each transport � Developing protocols for programs that use multiple modes of transport (ground, helicopter, and airplane) � Determining which mode of transport should be used and any condi tions, such as weather, that would preclude the use of a particular form of transport � Developing alternative plans for care of the patient if a transport cannot be accomplished � Ensuring that proper safety standards are followed during transport � Requiring the transportation services to follow established guidelines regarding maintenance and safety the director may delegate specific responsibilities to other persons or groups but retains the responsibility of ensuring that these functions are addressed appropriately. Referring Hospital Referring physicians should be familiar with the transport system, including how to gain access to its services and appropriately use its services. The refer ring physician is responsible for evaluating the patients condition and initiating stabilization procedures before the transport team arrives.
Statistical Tabulations Statistical tabulations for vital events related to pregnancy provide the medical and statistical community with valuable information on reproductive health and generate data on trends apparent in this country and worldwide treatment centers for drug addiction order 20mg citalopram with mastercard. This information often is disaggregated and used to examine specific events over time or within selected geographic locations symptoms 0f high blood pressure citalopram 40 mg lowest price. In informing the public about health issues symptoms cervical cancer buy cheap citalopram, media sources often report various statistical measures. Heightened public interest in health-related issues makes it essential that the medical com munity understand and have the capacity to interpret these statistics. The following explanations of statistical tabulations are intended to provide the reader with a better understanding of the measures used for events related to reproduction: Rate: A measure of the frequency of some event in relation to a unit of popu lation during a specified time period, such as a year; events in the numerator of the rate occur to individuals in the denominator. Rates express the risk of the event in the specified population during a particular time. Rates generally are expressed as units of population in the denominator (eg, per 1,000, per 100,000. Ratios: A term that expresses a relationship of one element to a different ele ment (where the numerator is not necessarily a subset of the denominator. For exam ple, the sex ratio of live births for 2008 was 1,048 males per 1,000 females. Live Birth Measures these measures are designed to show the rate at which childbearing is occurring in the population. The crude birth rate, which relates the total number of births to the total population, indicates the effect of fertility on population growth. The general fertility rate is a more specific measure of fertility because it relates the number of births to the population at risk, namely, women of childbearing age (assumed to be aged 15�44 years. An even more specific set of rates, the 502 Guidelines for Perinatal Care age-specific birth rate, relates the number of births to women of specific ages directly to the total number of women in that age group. Formulae for these measures are as follows: Number of live births to women of all ages during a calendar year 1,000 Crude birth rate = Total estimated mid-year population Number of live births to women of all ages during a calendar year 1,000 General fertility rate = Estimated mid-year population of women aged 15�44 years Number of live births + number of fetal deaths + number of induced terminations of pregnancy during a calendar year 1,000 General pregnancy rate = Estimated mid-year population of women aged 15�44 years Number of live births to women in a specific age group during a calendar year 1,000 Age-specific birth rate = Estimated mid-year population of women in same age group the sum of age-specific birth rates of women Total fertility rate = at each age group 10�14 through 45�49. Because the birth weight of the infant is included on the birth certificate, it is possible to tabulate and focus an analysis on selected groups of live births, for example, those weighing 500 g or more. Therefore, they can be shown by place of occurrence, by place of residence, and by kind of setting of delivery, such as at a hospital or home. Most tabulations of vital statistics are routinely calculated by place of residence of the mother, but they could be tabulated on another basis as well. Appendix F 503 Fetal Mortality Measures the population at risk of fetal mortality is the number of live births plus the number of fetal deaths in a year. Fetal death indices, defined by a minimum weight and gestational age, indicate the magnitude of late pregnancy losses. It is recognized that most states report fetal deaths on the basis of gestational age. Therefore, it is recommended that states adopt minimum reporting requirements of fetal deaths based on and labeled as specific birth weight rather than gestational age (see also �Fetal Death later in this appendix. In addition, statistical tabulations of fetal deaths should include, at a minimum, fetal deaths of those weighing 500 g or more. It is recognized that states will not be able to immediately translate data from gestational age to weight, and, for comparative purposes, it may be desir able to know fetal death rates for various gestational periods. Therefore, the collection of both weight and gestational age is recommended to allow for these comparisons. When calculating fetal death rates based on gestational age, the number of weeks or more of stated or presumed gestation can be substituted for weight in the previous formulae. Number of fetal deaths (x weight or more) during a period 1,000 Fetal death rate = Number of fetal deaths (x weight or more) + number of live births during the same period Number of fetal deaths (x weight or more) during a period 1,000 Fetal death ratio = Number of live births during the same period Perinatal Mortality Measures ^ Perinatal death is not a reportable vital event, per se, but is used for statistical purposes. Indices of perinatal mortality combine fetal deaths and live births with only brief survival (up to a few days or weeks) on the assumption that similar factors are associated with these losses. The population at risk is the total number of live births plus fetal deaths, or alternatively, the number of live births. Perinatal mortality indices can vary as to age of the fetus and the infant who is included in the particular tabulation. When perinatal death rates based on gestational age are calculated, the number of weeks of a stated or presumed gestational age can be substituted for weight in the formulae. When comparisons based on gestational age are desired, the generally accepted breakdown is as follows: � Perinatal period I includes infant deaths occurring at less than 7 days and fetal deaths with a stated or presumed period of gestation of 28 weeks or more. Therefore, they can be shown by place of occurrence, by place of residence, and by place of delivery, such as at a hospital or home.
