Failure to complete long-term follow-up may lead to complications that potentially could have been avoided symptoms iron deficiency purchase leflunomide line. All of these conditions can cause adverse effects (Table 1) that may negatively impact the patients physical and mental health symptoms 3 days dpo order leflunomide overnight delivery, quality of life medications cause erectile dysfunction cheap leflunomide 20 mg without a prescription, growth medications for anxiety purchase leflunomide canada, development symptoms juvenile rheumatoid arthritis buy 10 mg leflunomide with amex, education symptoms carbon monoxide poisoning cheap leflunomide 20mg visa, and employment. Therefore, the development of long-term adverse effects must be assessed on an ongoing basis (1-10). The patients medical team should work in close collaboration to provide comprehensive care. For example, it is important to diagnose hemochromatosis (iron overload), which can lead to chronic liver disease if left untreated. In particular, screening for primary or secondary cancers is of the utmost importance. For example, patients should be counseled to avoid sun exposure, because it could result in malignancies. This chapter explores emerging therapies that can translate into better care for those patients. We will describe three of the most promising therapies in this realm: gene therapy, stem cell therapy, and a combination thereof known as stem cell gene therapy (1). Good to Know Hematopoietic stem cells are rare blood cells found in the bone marrow and umbilical cord. These cells are unique because they have the potential to develop into any of the various types of blood cells found in the body. Doctors can harvest and store a patients hematopoietic stem cells before radiation or chemotherapy, or these cells can be obtained from a human donor. A medical procedure called hematopoietic stem cell transplantation transfers stored or donated cells to a patients body. There are many barriers to successful gene transfer: moving the genetic material into the cell, evading the cells defenses, moving the genetic material through the shell of the nucleus, and fnally prodding it to integrate into the cells own genetic code, or genome. To overcome these challenges, researchers have used viruses as so-called vectors to deliver genetic material into cells. Researchers have simply borrowed these properties to insert genes of interest into the patients cellular genome. Researchers have traditionally used the gamma retroviral vector in gene therapy studies, although new and improved lentiviral vectors boast the advantage of being able to transduce non-dividing cells. Among these pyroviruses, adenoviruses are considered advantageous because they deliver the gene into the cell without causing the virus to integrate into the cellular genome. The disadvantage of adenoviruses, however, is that they are more likely than other viruses to elicit an immune response in the recipient (4). When some of the patients cells are removed from the body so that this genetic manipulation can take place in a laboratory, the procedure is known as ex vivo (Latin for outside the living) gene therapy. Conversely, when a viral vector containing the healthy gene is injected directly into the patient, the procedure is known as in vivo (Latin for within the living) gene therapy. Since the 1970s, researchers have searched for safe and effective ways to correct disease-related genes in human cells. In gene replacement, a gene of interest is inserted at an almost random location in the patients genome. This method predictably causes non-physiological regulation of the delivered gene in its new location, or the inadvertent functional disruption of other genes near the insertion site (5-7). Gene editing, on the other hand, takes advantage of the genomes natural ability to repair itself through a process called homologous recombination, in which the faulty gene is corrected at its original locus without the insertion of new material. Gene editing does not typically result in gene dysregulation, and no other region of the genome is likely to be affected (8,9). This gene correction strategy relied on the ability to deliver a functional gene along with other related elements needed to promote sustained, high-level gene expression. The drawbacks of this approach included loss of physiological regulation of the treated gene, and disruption and possible dysregulation of other genes. Even with this unfortunate event, the overall outcome of the trial provided evidence that gene therapy is equivalent or superior to the previous standard of care (hematopoietic cell transplantation), providing superior immune function, improved disease-free survival, and a better quality of life (5,6,10,11). It is important to note that the effects of insertional mutagenesis may vary from patient to patient. It can take a long time for side effects to occur, as demonstrated by the gene therapy trials performed to date. Stem Cell Therapy Stem cell therapy vectors Traditionally, stem cell therapy has entailed the use of bone marrow cells; this method has been experimentally and clinically proven in many thousands of successful bone marrow transplants over the last 50 years. While embryonic stem cells provide an opportunity to understand more deeply how stem cells work, their use remains controversial and various biological and legal constraints prevent their therapeutic use. More relevant to clinical care are induced pluripotent stem cells, which are embryonic stem cell-like cells from the skin or blood of adults that have been engineered with the potential to develop into any other type of cell in the body. Good to Know Pluripotent stem cells are cells capable of developing into almost any type of cell in the body. Through a procedure called stem cell therapy, physicians introduce new, healthy stem cells into a patients body to help replace, repair, or regenerate diseased tissues. Hematopoietic stem cell transplantation usually uses stem cells from the bone marrow or umbilical cord blood of a matched donor. These cells are thought to be located in the walls of the blood vessels and to perform key functions, such as supporting hematopoietic stem cells in the bone marrow and modulating the immune response. Methods of stem cell therapy There are at least two methods of cell therapy: traditional hematopoietic stem cell transplantation and immunomodulation. Traditional hematopoietic stem cell transplantation involves replacing the entire blood-producing system of the recipient patient with that of a healthy donor. Immunomodulation, on the other hand, involves modifying the patients immune response. Good to Know Graft-versus-host disease occurs when immune cells in the transplanted tissue attack the patients own cells. Stem cells, for example mesenchymal stromal cells, can also play a role in tissue repair and healing after injury. Side effects of stem cell therapy the most notable side effect of stem cell therapy is tumorigenesis, or the uncontrolled growth of stem cells, which can give rise to benign or malignant tumors. Most cancers are thought to originate from so-called cancer stem cells, which are in many ways similar to normally functioning stem cells in their cellular processes and metabolic pathways. Because of this, some donor stem cells potentially can cause malignancies in the patient; indeed, donor 263 Fanconi Anemia: Guidelines for Diagnosis and Management derived leukemias have been reported in some recipients of hematopoietic cell transplantation. Multiple researchers have observed this phenomenon in animal models when mesenchymal stromal cells were transplanted from one organism to another and gave rise to cancers (26). In theory, additional side effects are possible because of the specifc functions of stem cells. Stem Cell Gene Therapy An effective gene therapy strategy must target the cell type relevant to the specifc disease. In most instances, the effects of gene correction are enhanced by the corrected cells ability to reproduce and repopulate the body in meaningful numbers. For this reason, many gene therapies have attempted to deliver genes to stem cells. It seems only logical that the parallel tracks of gene therapy and stem cell therapy should be joined in one concerted effort termed stem cell gene therapy. For reasons mentioned above, the leading strategy for gene therapy represents a shift away from gene addition, in which an entirely new gene is pasted into the genome with the help of viruses or transposons, and a move toward genome editing, whereby the pathogenic mutation is corrected in its natural gene location with the aid of newly engineered molecules called zinc fnger nucleases, transcription activator-like effector nucleases, or homing endonucleases. In this fashion, the pathogenic mutation is permanently changed to the normal sequence. This process also preserves the architecture of the genome and maintains control of the gene by the cells normal regulatory elements. One of the advantages of gene editing is its spectacular fexibility and range of use; it can be used for targeted delivery, tissue-specifc regulatory sequences, or transduction of cell types committed to tissue-specifc differentiation programs. Viral transduction, however, resulted in transient or no correction of hematopoietic cells, an observation consistent with only short-term functional gene complementation (27-30). Individuals with a human leukocyte antigen-matched sibling donor, an abnormal karyotype, or a serious infection are not eligible for the trial (3,31,32). Hans-Peter Kiem (University of Washington/Fred Hutchinson Cancer Research Center, Seattle), has been 265 Fanconi Anemia: Guidelines for Diagnosis and Management approved by the U. This trial incorporates the updated transduction procedures and a relatively brief overnight incubation of cells in low oxygen in the presence of a reducing agent. In addition to the procedures mentioned above, the vector design and treatment of the cells may greatly reduce the risk to the patient. This will likely require the use of genetic components such as weak promoters, strong insulators, and strong polyadenylation sequences to isolate the functions of the inserted genes from the genome and that of the genome from the inserted genes. As mentioned above, most future efforts will likely focus on combined modalities and attempt to minimize oxidative stress in these cells. For example, a combination of stem cell expansion, correction of hematopoietic stem cells and mesenchymal stromal cells from the same patient, and co-infusion of these cells may provide an ideal environment for engraftment of the gene-corrected hematopoietic stem cells (34-36). The frst step involves the coordination of clinical trials so that individual research centers can pool their collective knowledge and statistical power. The second step involves focusing on a common goal, such as the development of treatments that can be rapidly translated to clinics around the world. The third step involves implementing real-time data exchanges and allowing for the evaluation of these data on the basis of scientifc merit. The feld of gene therapy started with a visionary and a daring idea, but suffered from a dearth of preclinical data. The frst clinical trials were permitted only because of the high risks of living with such challenging genetic diseases and the risks and incomplete effcacy of alternative therapies such as hematopoietic cell therapy. Through the years, the feld of gene therapy has overcome several crises at the collision of public expectations and unintended side effects, and has emerged as an acceptable therapy in the treatment of several genetic disorders.

Head and Neck Cancer in the General Population Head and neck cancer encompasses a wide variety of tumors that typically begin in the squamous cells that line the moist, mucosal surfaces of the oral cavity, nasal cavity, pharynx (throat), and larynx (voice box). Approximately 30,000 individuals are diagnosed with head and neck cancer in the United States annually, and about 30% of patients with head and neck cancer succumb to their disease. Good to Know A second primary cancer refers to the presence of an additional, unrelated cancer in someone who was previously diagnosed with another type of cancer. Head and neck cancers are prototypic tobacco-related cancers, and the initial risk for the development of cancer and the subsequent risk for the development of second 271 Fanconi Anemia: Guidelines for Diagnosis and Management primary cancers is directly attributable to the duration and intensity of tobacco exposure. Tobacco-related cancers can also occur in non-smokers as a result of secondhand (environmental) smoke exposure. Southeast Asia has the highest incidence of carcinomas of the oral cavity and oropharynx due to the practice of chewing tobacco containing the betel nut. The rates of laryngeal and hypopharyngeal cancer, which develops in the bottom part of the throat, are signifcantly elevated in Italy, France, and Spain due to the high prevalence of alcohol and tobacco use in those countries. Because a detailed review of head and neck cancer is not feasible in this chapter, we recommend consulting reference textbooks (22 and 23). The use of tobacco and tobacco products should be discouraged categorically, including exposure to secondhand smoke. While it is best to abstain from alcohol use, individuals who consume alcohol should restrict their intake to no more than one drink equivalent per month. Therefore, maintenance of proper oral hygiene and routine dental evaluations are recommended. Surveillance should begin at age 10, which is based on literature reports of the earliest age at diagnosis with head and neck cancer. Distinguishing suspicious lesions from those that are non-cancerous requires the input of a health care provider with signifcant experience in the evaluation and management of head and neck cancer. Appropriate professionals may have dental, oral surgery, otolaryngology, or general surgery backgrounds supplemented with specialized training in head and neck cancer. Therefore, all mucosal surfaces of the head and neck region need to be examined thoroughly. Examination of the distal oropharynx (the back of the throat), nasopharynx (the uppermost part of the throat, between the nasal cavity and the soft palate), larynx, and hypopharynx (the bottommost part of the throat) requires the use of either a transoral mirror or a fexible fberoptic laryngoscope. Any patient with odynophagia (painful swallowing), dysphagia (diffculty swallowing), or other localizing symptoms merits evaluation with a barium swallow study and/or esophagoscopy. A positive margin indicates the presence of tumor cells near the edge of the tissue, which suggests that the cancer has not been completely removed. A free fap refers to the transplant of a piece of tissue from one site of the body to another for the reconstruction of a defect. For example, N0 describes a cancer that has not spread to nearby lymph nodes, whereas N1 indicates lymph node involvement. The values for T, N, and M are then combined to assign an overall stage to the cancer. Optimized medically means that a doctor has chosen the best treatment for a patient depending on his or her individual circumstances. A qualifed professional should perform a thorough head and neck examination every 6 months. If suspicious lesions are identifed, they should be biopsied; further management should be dictated by the results from microscopic evaluation of the tissue. Once a premalignant or malignant lesion has been identifed and appropriately treated, the frequency of surveillance examinations should be increased to once every 2-3 months.
That negative charge on the cell membrane is pri marily caused by which of the following The face labeled by asterisks in the freeze-fracture preparation shown below may be characterized as which of the following Generally possessing a paucity of intramembranous particles 100 Anatomy symptoms for pregnancy leflunomide 10mg on-line, Histology medicine nelly generic 10 mg leflunomide with visa, and Cell Biology 33 medications you cannot crush buy leflunomide 20 mg on-line.

Which of the fol lowing is most likely to decrease in the absence of band 3 protein A 56-year-old man who drinks a six-pack of beer a day medications known to cause weight gain purchase leflunomide canada, with higher alcoholic intake on weekends medicine 524 buy 10mg leflunomide, holidays, and special days, presents to the internal medicine clinic. Which of the following would increase membrane fluidity in the hepatocytes of this patients liver The asymmetry of the cell membrane is established primarily by which of the following Flipping proteins between the leaflets of the lipid bilayer Cell Biology: Membranes 101 36. When the MedAct unit arrives they find a patient with acute shortness of breath and audible wheezing. Auscultation reveals decreased breath sounds with wheezing on inspiration and expiration. The patient has taken her prescribed medica tions with no relief of symptoms prior to her 911 call. Her current medica tion is albuterol, a moderately selective 2-receptor agonist. They possess a single hydrophobic transmembrane segment in the form of an helix. They are arranged so that both the amino and the carboxy-terminals are located intracellularly Cell Biology: Membranes Answers 30. It is responsible for the fundamental structure of the membrane and provides the barrier to water-soluble molecules in the external milieu. Other membrane functions are performed primarily by proteins that function as receptors, enzymes (catalysis of membrane-associated activities), and transporters (answers b, c, and d). Connection to the cytoskeleton (answer e) is performed by members of the spectrin family of proteins reinforcing the membrane on the cytosolic side. The membrane consists of a bilayer of phospholipids with the nonpo lar, hydrophobic layer in the central portion of the membrane and the hydrophilic polar regions of the phospholipids in contact with the aqueous components at the intra or extracellular surfaces of the membrane. The polar head groups of the lipid bilayer react with osmium to create the trilaminar appearance observed in electron micrographs of the plasma membrane. IgA func tions in several ways, one of which is to coat pathogens with a negative charge that repels the polyanionic charge on the cell surface. In IgA deficiency, pathogens can more easily attach to the cell surface leading to persistent infec tions. The carbohydrate of biological membranes is found in the form of gly coproteins and glycolipids rather than as free saccharide groups (answer a). The polyanionic charge of the membrane is produced by the sugar side chains on the glycoproteins and glycolipids. Glycoproteins often terminate in sialic acid side chains, which impart a negative (polyanionic) charge to the mem brane. Similarly, the glycolipids (also called glycosphingolipids), particularly 102 Cell Biology: Membranes Answers 103 the gangliosides, terminate in sialic acid residues with a strong negative charge. Cholesterol (answer c) alters membrane fluidity (see figure below and question 34) and is amphipathic (hydrophilic and hydrophobic properties). Peripheral membrane proteins (answer d) are found primarily on the cytosolic leaflet of the membrane bilayer. A = Integral membrane protein, B = Glycoprotein, C = Peripheral membrane protein (more abundant on cytosolic surface), D = sugar, E = cholesterol, F = hydrophobic fatty acid chains (hydrophilic polar head groups are not labeled), G = glycolipid 32. Freeze fracture is a procedure in which the tissue is rapidly frozen and fractured with a knife. The fracture plane occurs through the hydrophobic central plane of membranes, which is the plane of least resistance to the cleavage force. They are described as the extracellular face (E face) and the protoplasmic face (P face). The cytoplasm is the back ing for the P face, which in general contains numerous intramembranous particles (mostly protein). The E face is backed by the extracellular space 104 Anatomy, Histology, and Cell Biology and in general contains a paucity of intramembranous particles (see upper part of figure) compared with the P face (labeled with asterisks). In the absence of band 3 protein, the bicar bonate buffering of the blood is reduced, leading to acidosis or lowering of blood pH. In addition to its func tional, bidirectional anion exchanger role, band 3 plays a key membrane struc tural role, since the cytoplasmic domain of the protein interacts with spectrin through an ankyrin bridge. The result of a null mutation in band 3 is the formation of erythrocytes that are small and round instead of biconcave (spherocytosis). Spherocytes are osmotically fragile because of their decreased surface area per unit volume (answer a). The accelerated hemolysis leads to increased bile production (answer c) and jaun dice. Rotational and lateral movements of both pro teins and lipids contribute to membrane fluidity. Phospholipids are capable of lateral diffusion, rapid rotation around their long axis, and flexion of their hydrocarbon (fatty acyl) tails. They undergo transbilayer movement (answer b), known as flip flop, between bilayers in the endoplasmic reticulum; however, in general this Cell Biology: Membranes Answers 105 does not occur in the plasma membrane. An increase in the amount of cholesterol relative to phospholipid (answer c) has been shown by a variety of physicochemical techniques to decrease fluidity in both biological and artificial membranes by interacting with the hydrophobic regions near the polar head groups and stiffening this region of the membrane. Association or binding of integral membrane pro teins with cytoskeletal elements (answer d) on the interior of the cell and peripheral membrane proteins on the extracellular surface limit membrane mobility and fluidity. Carbo hydrates are associated with the N terminals of transmembrane proteins that extend from the extracellular surface, not the cytoplasmic surface (answer c). Cholesterol is different from proteins and phospholipids that are asymmetrically distributed within the bilayer (answer d). The small polar head group structure of cholesterol allows it to flip-flop from leaflet to leaflet and respond to changes in shape. In contrast to cholesterol, most proteins and phospho lipids are capable of only rare flip-flop (answer e). For example, transbi layer movement of phospholipid is limited mostly to the endoplasmic reticulum. Binding to G-protein-linked receptors activates or inactivates enzymes bound to the plasma membrane (adenylyl cyclase or phospholi pase C) or opens or closes ion channels using G proteins. The receptors, as well as muscarinic cholinergic receptors and rhodopsin, are multipass transmem brane (answer a) proteins consisting specifically of seven hydrophobic spanning segments of the single polypeptide chain. In the hydrophobic environment of the lipid bilayer, in the absence of water, they form hydrogen bonds with each other. There is a remarkable homology between the cell-surface receptors linked to the G proteins. Receptors with intrinsic enzyme activity belong to a separate 106 Anatomy, Histology, and Cell Biology class of single-pass transmembrane proteins (answer d). All of these trans membrane proteins show a carboxyl terminus on the cytosolic side and N linked glycosylation sites on the extracellular surface (answer e). The pathologist uses anti-vimentin antibodies with immunocytochemistry to stain the biopsy tissue. The stability and arrangement of actin filaments as well as their prop erties and functions depend on which of the following A 47-year-old man presents with fatigue and over the next few years became progressively weaker, eventually becoming paralyzed.

The type of intermediate fil ament protein is relatively specific for cells derived from the three embryonic germ layers. Antibodies to intermediate filament proteins have been used by pathologists to determine the origin of tumors. Intermediate filament proteins have a structural role but also are involved in the anchorage of the proteins that form ion channels. Desmin is found in striated and most smooth muscle, except vascular smooth muscle. Therefore, the initiation phase of protein synthesis is regulated 116 Cell Biology: Cytoplasm Answers 117 by the small subunit of the ribosome (answer d). The fundamental structure of the actin molecule is the same no matter what the function or arrangement in a cell.
However medications contraindicated in pregnancy buy discount leflunomide on-line, patient preference is not and cannot be the primary factor in devising an allocation system for ventilators in an influenza pandemic; more patients will want ventilators than can be accommodated treatment centers for alcoholism cheap leflunomide online american express. A public health emergency such as an influenza pandemic treatment yeast infection child purchase genuine leflunomide on line, by virtue of severe resource scarcity medication 3 checks buy leflunomide 10mg online, imposes harsh limits on decision-making autonomy for patients and health care providers medicine universities 20 mg leflunomide overnight delivery. Nonetheless medicine 4h2 pill leflunomide 20mg, a just scheme must endeavor to support autonomy, when possible, in ways that also honor the duties of care 66 See generally Benjamin Berkman, Incorporating Explicit Ethical Reasoning Into Pandemic Influenza Policies, 26 J. For example, where an eligible patient for ventilator therapy has appropriately articulated the wish to forgo such treatment, that expression of autonomy should be honored. Furthermore, an allocation system should stress the provision of care that may be possible when ventilator therapy is not. An ethically sound allocation system includes alternative forms of medical intervention and/or palliative care for patients not eligible for ventilator therapy. Duty to Steward Resources the second element in the ethical framework for allocating ventilators is the obligation for government and health care providers to responsibly manage resources during a period of true scarcity. The effort to balance this obligation to the community of patients against the primary duty to care for each patient generates the ethical tension in devising an allocation system. Even under ordinary, non-emergency circumstances, health care providers may question whether the estimated benefit of an intervention merits the use of scarce resources. For example, health care providers currently struggle to decide whether a blood transfusion (or antibiotics, or surgical intervention) is appropriate or justified for a particular patient, given that the quantity of a particular resource is limited. Yet an emergency on the scale of a severe influenza pandemic forces health care providers to confront limits far more starkly than they now do. Patients, some of whom might survive under ordinary circumstances, cannot be given the standard level of resources at the expense of numerous other patients who will likely die without any resources at all. Providers need to balance the obligation to save the greatest possible number of lives against that of the obligation to care for each single patient. As the number of affected patients increase, accommodating these two goals require more and more difficult decisions. An allocation system incorporates ethical decision-making processes so that the duty to steward resources and the limitations it may place on individual care is recognized as fair and acceptable under emergency circumstances. Duty to Plan A motivating force in designing an allocation system is the knowledge that planning is an obligation. An absence of a plan leaves allocation decisions to exhausted, over-taxed, front-line health care providers, who already bear a disproportionate burden in an emergency. A failure to produce an acceptable plan for a foreseeable crisis amounts to a failure of responsibility toward both patients and providers. Guidelines are essential to uphold health care staffs commitment to patients, ethics, and to professionalism during a time of crisis. In addition, health care providers are aware that some who served in the aftermath of Hurricane Katrina faced accusations of criminal conduct. Appropriate guidance may help prevent both the actuality and the fear of similar consequences for those who provide care in a future emergency. Although plans are obligatory, the Guidelines represent a starting point for the public and decision-makers to discuss how scarce resources, particularly ventilators, should be allocated. The Task Force acknowledged that current access to health care is unequal; no allocation system for a crisis can resolve inequities in pre-existing health status resulting from unequal access. In addition, because the clinical parameters of an influenza pandemic are as yet uncertain, increasing the difficulty of predicting survival or duration of critical symptoms, the specifics of the clinical ventilator allocation protocol may evolve as data about the pandemic viral strain 36 Chapter 1: Adult Guidelines become available during a pandemic. Nevertheless, the government has a duty to plan for foreseeable emergencies, and this work product embodies the current, best efforts at an effective, fair plan aimed at saving the most lives in an influenza pandemic where there are a limited number of available ventilators. Distributive Justice A just system of allocation must be applied consistently and broadly to be fair to all. In addition, the same allocation system should be implemented across the State, and the decision to implement clinical ventilator allocation protocols must be authorized by the State. The timing and content of a just allocation system cannot fall to individual hospitals, but must be coordinated with the State. A just and equitable health care system cannot allow for more expansive access at a prestigious private facility and more restrictive access at a community or public hospital. Cooperative agreements to pool scarce resources among local hospitals may help alleviate initial shortages. The allocation of ventilators from State and federal stockpiles must take into account the ratio of local populations to available resources, and supplement those resources accordingly. Ethically sound responses to a public health emergency must not exacerbate disparities in access to care. Rather, planners must designate appropriate resources for the most vulnerable, whom are most likely to suffer the greatest impact in a public health emergency. Transparency Any just plan allocating ventilators requires robust efforts to promote transparency, by seeking broad input in the design of the plan and educating the public. The Department of Health and the Task Force will continue to publicize the Guidelines, and share them with health care leaders and the community. The general publics values must be evaluated and included, because it is the public that ultimately must live with the outcomes of the Guidelines. The assessment of public comment and feedback has been integrated into the Guidelines and contributes to the development of a just allocation process. The ongoing process of obtaining and incorporating feedback helps promote public trust in the Guidelines. Triage Decision-Makers: Officer or Committee A physician attending to a patient should have neither the main nor the sole responsibility for determining whether his/her patient is eligible for ventilator therapy. Instead, a triage officer or triage committee makes the determination about a patients level of access to a ventilator. Neither a triage officer nor any members of the triage committee should have any direct contact with patients. A patients attending physician provides a patients clinical data to a triage officer/committee who examines the data and makes the decision whether a patient is eligible for (or continues with) ventilator therapy based on the clinical ventilator allocation protocol. Use of a separate person/team to triage is essential for an effective clinical ventilator allocation protocol for several reasons. First, this framework permits attending physicians to 37 Chapter 1: Adult Guidelines fulfill their obligation to care for their individual patients without facing a conflict of interest; they can advocate for their patients and not also be responsible for deciding to withhold or withdraw ventilator treatment. Second, separating the attending physicians from the triage decision-makers also ensure that the person(s) in this role is a senior/supervisory clinician. This person(s) will have access to real-time information, which helps with balancing the need for ventilator treatment versus resource availability. Further, this person(s) will make allocation decisions consistently across a group of patients. Finally applying role sequestration enhances the capacity for maintaining professionalism by helping to decrease burnout and stress for health care providers providing direct critical care during the epidemic and for the decision-makers, and for all clinicians to sustain their integrity as healers. It is probable that patients in need of a ventilator are individuals who may be familiar to a triage officer/committee and efforts should be made by the facility to ensure that a triage officer/committee does not have access to the identity of patients. To minimize decision bias and potential conflicts of interest, a triage officer or triage committee member should recuse him/herself where appropriate. While the Draft Guidelines suggested the use of a triage officer, these revised Adult Guidelines acknowledge that because acute care facilities differ in size and available resources, it is not appropriate to conclude that a triage officer is the best model for all facilities. Thus, the Task Force recommended that individual institutions should determine whether a triage officer or triage committee is appropriate. For either a triage officer/committee model, the individual(s) should have the appropriate background and training to apply the protocol with confidence. The benefits and drawbacks of both paradigms are presented below and each hospital should determine which model best suits its needs. Because one individual is in charge of these crucial decisions in normal, non-pandemic conditions, it is logical to utilize the same model for the Guidelines. Ideally, an intensivist may be the best specialist to be a triage officer, because this type of physician has more experience with critical care patients. The use of a triage officer ensures consistency and efficiency because only one person makes the triage decisions. In a pandemic, an overwhelming amount of patient data may need to be examined, and a triage officer may experience burn-out. Rotating a triage officer responsibility among a small group of people could 68 See Centers for Disease Control and Prevention, Ethical Considerations for Decision Making Regarding Allocation of Mechanical Ventilators during a Severe Influenza Pandemic or Other Public Health Emergency,17 (July 1, 2011). In addition, if a triage officer is unable to perform his/her duties, there is the question of who makes the triage decisions. A triage team could help decrease burn-out and stress for the triage decision-makers, who could share the responsibility and obtain support from other members. In addition, inclusion of individuals from outside the medical or clinical community, such as ethicists or religious/pastoral care representatives, in the triage committee could provide a perspective from outside the medical profession, which may be comforting to the general public. However, the contribution of these non-medical members may be limited because the triage decision is based on clinical factors alone. Shortcomings of a triage committee include questions related to how to resolve 70 disagreement about triage decisions between members and how decisions are made if all members are not available during the pandemic. In addition, staffing may be a problem, particularly in smaller community hospitals that may not have the resources to form a triage committee. Pitfalls of an Allocation System In building a clinical ventilator allocation protocol, there are pitfalls that an allocation system must avoid. Emergency planning must not serve as a means to resolve long-standing disparities in health care access. For instance, an allocation system does not alleviate the need to provide adequate resources. In a resource-constrained environment, triage may lead to the acceptance of a lack of resources without challenging the problem of scarcity. A just system seeks to avoid triage by first implementing less drastic means of limiting and deferring the use of scarce resources. Before implementing any allocation system, appropriate steps may include cancellation of elective surgeries and altering patient to staff ratios. While the Guidelines incorporate specific clinical parameters on how to allocate ventilators to ensure that protocols are applied consistently throughout the State, there are drawbacks to a framework that is too rigid. Specifically, flexibility is necessary so that, if and when the Guidelines are needed, they are current with the latest data on the pandemic viral strain. As currently written, the Guidelines are based, when possible, on scientific data and previous emergency planning experiences, and reflect the most up to date and commonly accepted medical data. The Guidelines are intended to allow for flexibility; they should be updated and revised as there are advances in clinical knowledge or changes in societal norms. As a severe pandemic is unfolding and real-time data on the pandemic viral strain become 69 See Rubinson et al. Additionally, the Guidelines must not be used to summarily resolve the controversial question of ventilator use for severely and permanently impaired patients. Quality of life judgments must not serve as a substitute for ethically sound principles that are available for public scrutiny. The Guidelines must reflect our common duty to protect the rights of the disabled, even while potentially encompassing them in an allocation system. Health care providers and family members will be reluctant to withhold/withdraw ventilators from patients. Guidelines that rely heavily on withdrawal of ventilators generate great concern and controversy and may be set aside in an emergency. Further, the experience of withdrawing ventilation is traumatic for all concerned, including health care staff. Doctors and nurses forced to extubate patients, even to save other patients, may not recover full professional confidence until long after the pandemic is resolved. Finally, the withdrawal of ventilation 71 without patient consent raises significant liability issues; again, appropriate guidelines limit instances of tragic choices. The Task Force and the various Workgroups involved in developing these Guidelines accepted the concept of removing patients with the highest probability of mortality from ventilators to give patients with a higher likelihood of survival an opportunity for ventilator therapy. However, they struggled with the notion of removing less ill patients from ventilators, particularly those who might recover with continued ventilator treatment beyond a certain time period that is longer than that prescribed in an allocation protocol. The Guidelines reflect an effort to address this tension by minimizing circumstances that require patient extubation, the most ethically and emotionally challenging aspect of any clinical ventilator allocation protocol. Triaging Ventilator-Dependent Chronic Care Patients Notably, the number of ventilators in chronic care facilities is not insignificant. The Department of Health estimates 1,902 ventilators are in nursing homes and chronic care 72 facilities. There was considerable debate both before and after the publication of the Draft Guidelines on whether ventilator-dependent chronic care patients should be triaged by the clinical criteria at the chronic care facilities. After additional consideration and review of public comments, the Task Force agreed with the 2006 Adult Clinical Workgroups recommendation that distinctions should be maintained between acute and chronic care facilities once the Guidelines are implemented, permitting chronic care facilities to maintain their specific mission. Patients using ventilators in chronic care facilities are not subject to the clinical protocol. If such patients require transfer to an acute care facility, then they are assessed by the same criteria as all other patients, and the possibility exists that these patients may fail to meet criteria for continued ventilator use. These facilities should implement procedures that would treat these patients onsite as much as possible so that only urgent cases are sent to acute 73 care facilities. Barriers to transfer are appropriate and likely during a phase in which acute care hospitals are overwhelmed. However, this approach may be problematic because it may not provide equitable health care to person with disabilities, and may place ventilator-dependent individuals in a difficult 74 position of choosing between life-sustaining ventilation and urgent medical care. Some argued that this strategy was contrary to the aim of saving the most lives because denying ventilator therapy to a ventilator-dependent person is different from denying the ventilator to someone who has a high probability of mortality who might have qualified for a ventilator under non-pandemic circumstances. Thus, if the ventilator is removed from a person known to depend upon it, s/he will not survive, regardless of the reason requiring hospitalization.
As an example medications januvia purchase leflunomide 20 mg amex, the rodent yolk sac placenta continues to function as an organ of transport for a much greater part of gestation than in the human treatment 5th disease cheap 20 mg leflunomide otc. Thus species differences in placental function and structure may affect the ability to apply teratogenic data developed in one species directly to other species medicine technology cheap leflunomide 20 mg on-line, including the human (Brent 1976) medicine 751 leflunomide 10 mg low price. As pharmacokinetic techniques and the actual measurement of metabolic products in the embryo become more sophisticated medicine in balance order leflunomide in united states online, the appropriateness of using animal data to predict human effects may improve medications ordered po are cheap leflunomide 10 mg otc. While it has been alleged that the placental barrier was protective, and therefore harmful substances did not reach the embryo, it is now clear that there is no placental barrier per se. Yet the package inserts on many drugs state that this drug crosses the placental barrier (Brent 1982). The uninitiated may infer from this statement that this characteristic of a drug is both unusual and hazardous. It would be a rare substance that could cross the placental barrier in one species, yet be unable to reach the fetus in another. No such chemical exists, except for selected proteins and many macromolecules whose actions are species-specific. The genetic constitution of an organism is an important factor in a species susceptibility to a drug or chemical. More than 30 disorders of increased sensitivity to drug toxicity or effects have been reported in humans due to an inherited trait (McKusick 1988). The effect of a drug or chemical depends on both the maternal and fetal genotypes, and may result in differences in cell sensitivity, placental transport, absorption, metabolism (activation, inactivation, active metabolites), receptor binding, and distribution. Differences in any of 138 these areas may account for some variations in teratogenic effects among species and in individual subjects. Evaluation of Drugs and Chemicals for Potential Teratogenicity in the Human While human epidemiological studies and clinical teratology observations are the foundation of teratogen discovery, chemicals and drugs can be evaluated for fetotoxic potential using in vivo animal studies and in vitro systems. It should be recognized that these nonhuman testing procedures are only one component in the process of evaluating the potential teratogenic risk of drugs and chemicals in humans. When possible, the evaluation of drug and chemical teratogenicity should include data obtained from human epidemiological studies, secular trend data in humans, animal developmental toxicity studies, the dose-response relationship to the teratogen and the relationship to the human pharmacokinetic equivalent dose in the animal studies, and considerations of biological plausibility (table 6) (Brent 1978, 1983, 1986; Shepard 1986). This method is of greatest value when used to evaluate chemicals and drugs that have been in use for some time, and (to a lesser extent) to evaluate new drugs that have a similar mechanism of action, structure, pharmacology, and purpose relative to other agents that have been extensively studied. Human teratogens identified since the thalidomide tragedy by human epidemiological studies, alert physicians or scientists, and/or animal studies. Few human teratogens have been initially discovered from animal experiments (table 7). Animal experiments are very helpful in supporting consistent findings discovered in human epidemiological studies or to study mechanisms of teratogenesis and the pharmacokinetics of reproductive toxins. Some investigators and regulatory agencies divide drugs and chemicals into teratogenic and nonteratogenic compounds. In reality, teratogenic potential can only be evaluated if one considers the agent, the dose, the species, and the stage of gestation at the time of administration. For 140 example, vitamin A and aspirin are not teratogenic during the sensitive organogenetic period if used in their appropriate dose, although they are teratogenic at higher exposures. Potential human teratogens constitute the largest group, because it includes all drugs and chemicals that can produce embryotoxic and fetotoxic effects at some exposure. Since these exposures do not occur or are not attained in humans, they usually represent no risk or minimal risks to the human embryo. The contributions of clinical teratologists and dysmorphologists clearly indicate that proven teratogens do not have the ability to produce every birth defect. More importantly, the concept of the syndrome in clinical medicine is probably more 141 appropriate in clinical teratology than any other area of clinical medicine. Many teratogens can be identified on the basis of the malformations that are produced. The syndromes may not always be separable, and environmentally produced birth defects may be confused with genetically determined malformations. As an example, a patient with bilateral radial aplasia and a ventricular defect may have Holt-Oram syndrome or thalidomide teratogenesis. It may or may not be possible to make a definitive diagnosis, even with a history of thalidomide ingestion during pregnancy. The specificity of some environmental teratogens can sometimes point to the mechanism or site of action. Similar symptoms or signs appear in many teratogenic syndromes and are therefore not very discriminating, such as growth retardation or mental retardation. On the other hand, rare or specific neurologic effects such as deafness, retinitis, or the pattern of cerebral calcifications may point to a specific teratogen. Epidemiologists sometimes use poor judgment when collating and classifying malformations. In many of the studies, limb defects that are clearly related to problems of organogenesis are classified with congenital amputations. Yet it is very unlikely that any agent being studied is responsible for both types of malformations. It is clear that epidemiological studies could be markedly improved if there were more input from clinical teratologists in planning and performing the studies. In the past few years, new teratogens that produce vascular disruptive phenomena have been reported, such as chorionic villus sampling, misoprostol, and most recently cigarette smoking. Environmental influences on human teratogenesis: Effects, associations, and allegations. Threshold teratogenic dose is likely; varies in individuals due to multiple factors. Androgens Masculinization of female embryo: Effects are dose dependent; stimulates clitotomegaly with or without fusion of growth and differentiation of sex labia minora Nongenital steroid receptor-containing tissue. If a woman becomes pregnant, therapy can be changed during the first trimester without increased risk of teratogenesis. Caffeine Teratogenic in rodent species with Exposure to 300 mg caffeine per day or doses of 150 mg/kg. No evidence studies indicate small differences in that a fetal caffeine syndrome exists for growth and pregnancy loss in the any malformation or group of caffeine-exposed groups; many other malformations. Environmental influence Reported effects or associations Comments Carbamazepine Minor craniofacial defects (upslanting Anticonvulsant; little known palpebral fissures, epicanthal folds, concerning mechanism.

Fetopathology amputation, cerebral infarctions and likely due to decreased uterine blood certain types of visceral and urinary flow and fetal vascular effects. Poor nutrition Significant risk of deleterious effects accompanies drug abuse, and multiple on fetal outcome. Because of the disruptive effects, but can occur in the mechanism of cocaine teratogenicity, a latter portion of the first trimester as well-defined cocaine syndrome is not well as the second and third trimester. Risk 10 to 25 percent anatomical defects such as absent during 8th to 14th week of gestation. Cyclophosphamide Growth retardation, ectrodactyly, Anticancer, alkylating agent; requires syndactyly, cardiovascular anomalies, cytochrome P450 monooxydase and other minor anomalies. The dose that increases risk of genitourinary abnormalities in the male is controversial. Diphenylhydantoin Hydantoin syndrome: microcephaly, Anticonvulsant; direct effect on cell mental retardation, cleft lip/palate, membranes, folate, and vitamin K hypoplastic nails and distal phalanges; metabolism. Metabolic intermediate characteristic, but not diagnostic facial (epoxide) suggested as the teratogenic features. Infectious agents Cytotoxic effects and inflammatory responses from fetal infections interfere with organogenesis and/or histogenesis. Characteristic syndromes related to the specific tissue localizaton and pathologic characteristics of the infectious agent and the duration of infectious process in embryo and fetus. Defects include mental retardation, deafness, cardiovascular malformations, cataracts, glaucoma, microphthalmia. Herpes simplex Generalized organ infections, microcephaly, hepatitis, eye defects, vesicular rash. Parvovims B 19 Infection can result in erythema infectiosum in children; in the fetus can result in hydrops fetalis and fetal death. Great risk of severe neonatal varicella if maternal infection occurs in last week of pregnancy. Environmental influence Reported effects or associations Comments Infectious agents (cont.

Methylmercury Minamata disease: cerebral palsy, Organic mercurials have a propensity microcephaly, mental retardation, to accumulate in lipid tissue, causing blindness, cerebellar hypoplasia. Since most cases are the result of accidental environmental exposure, estimation of risk is usually retrospective. Misoprostol A synthetic prostaglandin analog that is Classical animal teratology studies used illegally by millions of women for would not be helpful in discovering the purpose of abortion. Environmental influences on human teratogenesis: Effects, associations, and allegations (continued). Environmental influence Reported effects or associations Comments Oxazolidine-2,4-diones Fetal trimethadione syndrome: Anticonvulsants; affects cell membrane (Trimethadione, paramethadione) V-shaped eyebrows, low-set ears with permeability. Copper chelating agent; produces copper deficiency inhibiting collagen synthesis and maturation. Environmental influence Reported effects or associations Comments Progestins Masculinization of female embryo Stimulates or interferes with sex steroid exposed to high doses of some receptor-containing tissue. Dose of progestins in modem oral contraceptives presents no masculinization or feminization risks. Radioactive isotopes Tissue and organ-specific damage Higher doses of radioisotopes can dependent on the radioisotope element produce cell death and mitotic delay. If Effect is dependent on dose, administered to pregnant mother can distribution, metabolism, and cause fetal thyroid hypoplasia after the specificity of localization. Microtia, dermatoses; retinoids can cause direct anotia, thymic aplasia, and other cytotoxicity and alter programmed cell branchial arch and aortic arch death; affect many cell types, but abnormalities. Retinoids, topical (Tretinoin) Case reports of malformed offspring of Systemically administered retinoids mothers who used topical tretinoin for clearly have varying teratogenic treatment of acne or skin aging. Topical administration of studies reported do not suggest that tretinoin in animals in therapeutic topical tretinoin presents a reproductive doses are not teratogenic; massive risk. The epidemiological studies, exposures can produce maternal animal studies, and absorption studies toxicity and reproductive effects. More in humans do not suggest a teratogenic importantly, topical administration in risk. Maternal or placental complications Increased postnatal morbidity and can result in fetal death. Some studies report smoke contains many components, increases in anatomical malformations; nicotine can result in vascular spasm most studies do not report an and vasculitis which can result in a association, At present, no syndrome is higher incidence of placental associated with maternal smoking, pathology. Poor placental perfusion except for the recent report of vascular could account for the decreased fetal disruptive phenomena. Sonography (ultrasound) No confirmed detrimental effects Levels and types of medical resulting from medical sonography. Tetracycline Bone staining and tooth staining can Antibiotic; effects seen only if occur with therapeutic doses. Persistent exposure is late in the first or during high doses can cause hypoplastic tooth second or third trimester, since enamel. No other congenital tetracyclines have to interact with malformations are associated. While it esophageal or duodenal atresia, is likely that one or more of the anomalies of external ears, kidneys, theories have elements of the truth, the and heart. The thalidomide syndrome, etiology of thalidomide teratogenesis while characteristic and recognizable, has not been definitively determined. Thyroid: Iodine deficiency, iodides, Hypothyroidism or goiter; neurologic Fetopathic effect of endemic iodine radioiodine, antithyroid drugs and aural damage is variable. Fetopathic effect of iodides, antithyroid drugs, and radioiodine involves metabolic block, decreased thyroid hormone synthesis and gland development. Maternal intake of 12mg of iodide per day or more increases the risk of fetal goiter. Environmental influence Reported effects or associations Comments Valproic acid Primarily facial dysmorphology and Anticonvulsant; little is known about neural tube defects. Small percent, but the risk for facial head size and developmental delay dysmorphology may be greater. Vitamin D Large doses given as vitamin D Mechanism likely to involve a prophylaxis are possibly involved in disruption of cell calcium regulation.
