Initial molecular experiments with estrogen on neuronal Steroid hormones that alter the seizure threshold by altering excitability demonstrated complex effects, altering excitability the overall excitability of neurons are termed neuroactive through both actions on neuronal membranes and on second steroids or neurosteroids. Further, seizures can alter the levels messenger systems, each with a specific time course of activity. It has since been concluded that the effects of estrogen in the Effects of Neurosteroids brain follow two avenues, either through genomic or through on Neuronal Excitability nongenomic pathways (22). The effects binding affinity for estradiol but have differential affinity to of these hormones, as well as another neuroactive reproducother estrogens, such as phytoestrogens. Neurophysiologic effects of exogenous and endogeand have cell-specific expression. However, there is a high nous neurosteroid can influence seizures and epilepsy; theredegree of homology between these receptor types and they can fore, this initial discussion provides a basis for some of the be present even within the same cell type (24). The classic genomic pathway has a specific time course, with an onset between minutes to hours and a long duration of Estrogen action. This pathway leads to regulation of protein synthesis Early whole animal and even human experiments have shown by a direct or an indirect mechanism. Specifically, estrogen dose, route of administration, acute central chloride-selective ion channel (44). The major isoversus chronic administration, natural hormonal milieu, and forms consist of two subunits, two subunits, and one estrogenic species can alter whether estrogen is proconvulsant 2-subunit, and are primarily localized to synapses (45). This increases the estrogen also influences its modulating effects on neuroexchloride current through the channel, hyperpolarizing the cell citability. This differential effect may be due to opposing and resulting in reduced cellular excitability. For example, mixture of conjugated equine estrogens and estrone has higher prolonged exposure to allopregnanolone in rats causes proepileptogenic potency compared to estradiol (8). This dynamic quality linked to its complex activity in the brain, and further, the has implications for seizure threshold during menstrual examples cited herein have ready extrapolation to the use of cycling, although the alterations in receptor composition are estrogen in humans. Complicating progesterone picture, both progesterone and allopregnanolone exacerbate Progesterone seizures in animal models of absence epilepsy (49,50). In contrast, progesterone has long been known to have a seizure-protective effect, as demonstrated in early studies. Testosterone High doses induce sedation and anesthesia in rats and in the neurophysiologic activity of testosterone is no less comhumans (28), primarily as a result of actions of the metabolite plex than the previously discussed reproductive hormones. Progesterone reduces spontaneous interictal Androgens are irreversibly converted in the body to two major spikes produced by cortical application of penicillin (29), and classes of biologically active metabolites: estrogens, formed suppresses kindling (30) and focal seizures (31) in animals. Estrogen has proconvulsant potential, since been discovered to be through its conversion to the neuas outlined above, while the 5 reduced androgens, by conrosteroid allopregnanolone (40). Prolactin initiates milk synthesis in the mammary glands and More recently, two other endogenous testosterone metabolites affects growth, osmoregulation, and fat and carbohydrate present in fairly high concentrations in men, androsterone and metabolism. Prolactin also inhibits sexual behavior (67) and etiocholanolone, have also been found to have anticonvulsant promotes parental behavior (68). Pituitary induced seizures in rats, pretreatment with high doses of the prolactin increases more than twofold after generalized conaromatase inhibitor letrozole (which blocks the conversion of vulsive seizures, most complex partial seizures, and simple partestosterone to estrogen) markedly increased the seizure tial seizures involving limbic structures, but in general not after threshold compared to the effect of testosterone alone (57). The increase occurs within 5 minutes, is maximal by cortical distribution of steroid hormone receptors may account 15 minutes, and persists for 1 hour (74). Other changes include for some of the differential effects of each steroid hormone on elevation in corticotropin and cortisol following both convulneuronal excitability, endocrine function, and reproductive sions and stimulation of mesial temporal lobe structures. Neocortical receptors for the basolateral nuclear group inhibits its release (76), dependestrogen in the immature brain are largely absent after puberty ing on which group is affected by excitation of the amygdala. Anatomic specificity and varying distribution might the inhibitory or stimulatory effect ultimately alters release of account, in part, for changes in seizure expression with the corresponding pituitary hormones (77), as does seizurechanges in reproductive function. These important experiments clearly indiaffect an important brain structure critical for regulating cate a mechanism by which seizures and epilepsy disrupt this reproductive and sexual behavior, the hypothalamus. The folfinely tuned hormonal feedback system by affecting central lowing section serves as a foundation for how reproductive nervous system reproductive regulation, which could then dysfunction can occur in epilepsy, including an increased rate adversely modify gonadal steroidogenesis and morphology. A recent levels, and further, this alteration has been shown to be report in men with epilepsy documents that pulsatile secretion reversible. In an amazing experiment in female rats that had withdrawing valproate resulted in decreases in these paramepilocarpine-induced seizures, an increased incidence of acyclicters but the small number of subjects in this subset (10 ity was found after 2 to 3 months of observation. Serum nificantly in men after stopping carbamazepine, while there testosterone was increased in epileptic rats, whereas estradiol, were no significant changes in 17 estradiol progesterone, progesterone, and prolactin were not. Locock first described the menstrual cycle and its relationship with epilepsy (103). Epileptic seizures usually occur in an unpredictable pattern; however, menstrual exacerbations have Biologic Mechanisms documented up to 70% of women with epilepsy. Despite the clear and documented relationship, many clinicians discount the sensitivity of neurons to the modulating effects of individthe association when brought up by female patients. This is ual steroid hormones changes after puberty and in response to contributed to by the lack of specific treatment for catamenial fluctuations in basal levels of steroid hormones over a reproepilepsy and an incomplete understanding of the cause. In contrast to its effects in postpubertal rats, estrogen does not alter the rate of amygdala the Normal Menstrual Cycle kindling in prepubertal male and female rats. Rats castrated prepubertally have higher seizure thresholds to minimal and the average menstrual cycle is 28 days; however the normal maximal electroshock than do animals castrated after puberty range is 24 to 35 days. The menstrual cycle has varies so as to maintain homeostatic regulation of brain two phases: the follicular phase (days 1 to 13) and luteal phase excitability (4,108,109). The follicular phase consists of the ovarian folseizure onset induced by chemical convulsants (bicuculline, licles growing and the dominant follicle with the most follicupicrotoxin, pentylenetetrazol, and strychnine) changes over lar receptors becoming the ovulatory follicle. The nondominant follicles chemical convulsants than are females in diestrus and males, degenerate. In the luteal phase, the dominant follicle forms the whereas infusion of a progesterone metabolite increases the corpus luteum, which produces progesterone.

Phenytoin has been shown to be useful in neuropathic pain In one study of elderly patients treatment of diabetes cheap duphalac 100 ml on-line, phenytoin and valproic (145) symptoms 8 days post 5 day transfer purchase cheap duphalac on-line, motion sickness (146 medications not to be taken with grapefruit duphalac 100 ml line,147) medications lisinopril buy duphalac, cardiac arrhythmias, conacid had similar effects (171), whereas a second study tinuous muscle fiber activity syndrome, myotonic muscular reported no cognitive impairment resulting from modest dystrophy, and myotonia congenita (148). It may also have a increases in serum phenytoin concentrations (between role in the treatment of recessive dystrophic epidermolysis bul11 g/mL and 16 g/mL) (172).

Therapeutic levels of phenytoin administered rectally have not been maintained in patients with seizures (238). Fosphenytoin For maintenance therapy, the nonlinear pharmacokinetics and wide interindividual variability in metabolism and Concentration-Dependent Effects absorption necessitate individualized regimens. The typical Intravenous fosphenytoin infusion has a favorable side-effect initial dose of 300 mg/day results in concentrations between profile (8,105,225). The local reactions associated with 10 and 20 g/mL in fewer than 30% of patients, and more administration of parenteral phenytoin solution (infusion-site than 57% will achieve concentrations below 10 g/mL (41). Pain at the site of fosphenytoin and 20 g/mL in approximately 45% of otherwise healthy infusion is rare, but 48. Pruritus or tingling on clinical response, increasing dosage for lack of seizure conappears soon after an infusion starts, abates rapidly when the trol or lowering dosage for concentration-dependent toxic infusion stops, and can be reduced or abolished by slowing the reactions.

This ability is highly effective in infection control as a first line of defence (Eckmann) medicine mountain scout ranch duphalac 100 ml with mastercard. At the mucosal surface medicine kidney stones order duphalac 100 ml on-line, immunoglobulins modulate this system of defence (Johansen et al asthma medications 7 letters duphalac 100 ml with amex. The gastric mucosal surface protects the gastrointestinal tract against this acid and medicine queen mary discount duphalac 100ml fast delivery, the protein digesting enzyme, pepsin. Improved critical care management of patients with single organ failure has reduced mortality, but increased the risk of multiple organ dysfunction syndrome (C. In the healthy person, the intestinal epithelial barrier selectively enables the movement of molecules through the epithelium; however, Doig et al. Damaged intestinal mucosa plays a key role in increased permeability (Johnson & Kudsk, 1999). Without adequate nutrition, the ability to mount an inflammatory response is diminished (Griffiths, 2007). Enteral stimulation enhances immune defences (Kudsk, 2001) and facilitates the hosts protection from bacteria and toxic products (Kudsk, 2002). It has also been suggested that commencing enteral nutrition may also restore intestinal anatomy and function (Grant, 2006). Initiating enteral nutrition early as a means to ameliorate septic complications is purported to be important. For example, a meta-analysis in 1992 highlighted the potential for early enteral nutrition to reduce the development of septic complications (Moore et al. Furthermore, research on mice has demonstrated a reduced rate of death when subjects are enterally fed as opposed to parenterally fed (Fukatsu et al. What this research highlights is that enteral nutrition is essential to the promotion of health in the critically ill patient and thus, ensuring the effective and adequate delivery of this critical component of intensive care is crucial. The impact of critical illness on the gastrointestinal system Reduced gastric motility Critical illness has been associated with reduced gastric motility (Dive, Moulart, Jonard, Jamart, & Mahieu, 1994; Gue, 2006). Stress alters gastrointestinal motor function and gut motility, particularly inhibiting gastric emptying (Gue). The critically ill mechanically ventilated patient has less peristaltic activity, particularly in the stomach, compared to that of healthy individuals (Dive et al. A literature review addressing aspects of critical illness that impact on gastrointestinal motility discussed the impact of both acute illness and therapeutic interventions such as opioids, fi-adrenergic blockers, and anticholinergic drugs (Fruhwald, Holzer, & Metzler, 2008). Several factors that reduce the natural defence mechanisms of the gastrointestinal tract were discussed, including abdominal surgery, haemodynamic instability, fluid and electrolyte alterations, vasoactive medication, sedation and analgesia. The provision of enteral nutrition to ameliorate the impact of these has been purported, however patients would require adequate intestinal motility (Fruhwald et al. One method of promoting intestinal motility is the administration of prokinetics to facilitate gastric emptying (Deane, Fraser, & Chapman, 2009). Potential for aspiration Critical illness has also been linked with the aspiration of gastric contents (Bullock, Waltrip, Price, & Galandiuk, 2004; Elpern, 1997; Grant, 2006). In the intubated patient, the endotracheal tube stents the glottis open, and if a nasoor oro-gastric tube is present this stents the oesophageal sphincter open. This may predispose the intubated and enterally fed patient to aspiration (Bullock et al. Gastric distension may result in gastroesophageal reflux and ultimately pulmonary aspiration (Grant). Despite the use of cuffed endotracheal tubes, these do not reliably prevent aspiration of substances into the lower airway (Elpern). Improving the delivery of enteral nutrition In an effort to mitigate the potential risks associated with delivering enteral nutrition, standardisation of practice has been proposed as one method to improve the management of enteral nutrition. The lack of reliable and valid research related to the effective delivery of enteral nutrition, may mean that there is a reliance on largely unchallenged tradition and rituals (Marshall & West). Marshall and West identified that the strategies for the management of enteral nutrition may result in insufficient delivery of feed. Evidence-based guidance the effective use of an algorithm has been shown to improve the delivery of prescribed enteral nutrition rates (Adam & Batson, 1997; Bowman et al. What these studies highlight is that having a protocol or algorithm to guide enteral nutrition delivery is of benefit. Furthermore, the stomach has previously been identified as a source of bacteria for colonising the trachea in the mechanically ventilated critical care patient (Pingleton, Hinthorn, & Liu, 1986; Tryba, 1991). These malnourished patients had a higher incidence of complications and fewer were discharged from the hospital. Underfeeding was associated with malnutrition, and overfeeding was associated with poor glycaemic control and impaired weaning from mechanical ventilation (Reid, 29 2006). Comparatively, overfeeding predominantly occurs when patients receive both an oral and enteral diet, and when patients are delivered a nutrient dense enteral formula (Reid, 2006). Nutrients are well matched to requirements of the immune response in the healthy person, but these are confounded by the inpatients variables of immobility and continuous nutrient delivery in the critically ill (Griffiths, 2007). This highlights the importance of facilitating the safe delivery of enteral nutrition, both to achieve caloric requirements and to mitigate a potential risk of aspiration. The underlying assumption that the stomach has a fixed volume capacity, and measurement of the volume of stomach contents enables prediction of potential overflow into the oesophagus and increased aspiration risk, has been dismissed as inherently flawed (McClave & Snider, 2002). This premise for aspiration risk assessment may be further undermined by Metheny et al. Furthermore, the assumption that enteral feeding intolerance leads to the development of pneumonia has also been questioned. Other methods have been proposed in the literature as a measure to assess gastric 31 emptying including scintigraphy, the paracetamol absorption test, breath tests, refractometry, ultrasound, and gastric impedance monitoring (Moreira & McQuiggan, 2009). Moreira and McQuigganfis narrative review found refractometry to be the most appropriate of these methods. A refractometer measures the degree of light bending between substances of different densities (Chang, McClave, Hsieh, & Chao, 2007). Despite this, high gastric residual volumes have been identified as one of the primary reasons for discontinuing enteral nutrition (McClave et al. Literature and systematic reviews were sought through a search of electronic databases. There was considerable disparity in the recommendations and guidelines of the professional groups and the reviews internationally. However, each of these latter higher recommendations relied heavily on the review of McClave and Snider (2002). The most common recommended action was to reduce the enteral 36 nutrition infusion rates (Cerra et al. Other recommendations included to cease the enteral nutrition (American Society for Parenteral and Enteral Nutrition Board of Directors & the Clinical Guidelines Task Force, 2002; Bowman et al. Some recommendations included the combination of several of the above actions, for example, to introduce prokinetics and implement aspiration risk reduction methods. The quality of evidence for the basis of these recommendations varied considerably. Of the 15 recommendations, three were clearly based on a reproducible search strategy (Edwards & Metheny, 2000; Heyland et al. These recommendations were supported from sources ranging from a single expert opinion or a single randomised controlled trial, to a systematic review of several research trials, which reflects the disparity in the rigour of the evidence-base. Systematic review objectives What has been highlighted so far is the potential scope for a systematic review to inform this topic more effectively than the existing literature to date. It is essential to balance important benefits against important harms when administering enteral nutrition and this is demonstrated in the objectives of this systematic review. The key research objectives included to: develop an appropriate research method to answer the question; conduct the systematic literature search; critically appraise the results of the systematic literature search; discuss the results of the systematic review of the literature considering the position of key reference groups related to this subject; identify limitations of the systematic review; 38 draw on implications for current practice to be disseminated; and finally, identify future opportunities for research. The implications of tradition, ritual, and evidence based practice in nursing were considered in association with optimising the delivery of enteral nutrition. The aim of the systematic review was identified and the overarching objectives were outlined. Clinical practice guidelines and review recommendations were identified and critiqued. There is discussion of the rationale for conducting a systematic review and meta-analysis in order to answer the objectives of this research project. The format of the systematic review is addressed, specifically why the Cochrane Collaboration methodology was used for the systematic review, and the structure of the Cochrane systematic review is described.

Consequently, internally generated development amortized on a straight line basis over the useful life of the expenses arising before marketing approval has been obtained, software from the date on which the software is ready for use. Other intangible assets acquired in a business combination Some industrial development expenses (such as those incurred in developing a second-generation synthesis process) are Other intangible assets acquired in a business combination which incurred after marketing approval has been obtained, in order to relate to in-process research and development and currently improve the industrial process for an active ingredient. The some clinical trials, for example those undertaken to obtain a related deferred tax liability is also recognized if a deductible or geographical extension for a molecule that has already obtained taxable temporary difference exists. Rights to products currently marketed by Sanofi are amortized on Separately acquired research and development a straight line basis over their useful lives, determined on the basis of cash flow forecasts which take into account the patent Payments for separately acquired research and development are protection period of the marketed product. Property, plant and equipment (i) controlled by Sanofi, (ii) expected to provide future economic benefits for Sanofi, and (iii) identifiable. Consequently, upfront and milestone approach to accounting for property, plant and equipment is payments to third parties related to pharmaceutical products for applied. Under this approach, each component of an item of which marketing approval has not yet been obtained are property, plant and equipment with a cost which is significant in recognized as intangible assets, and amortized on a straight line relation to the total cost of the item and which has a different basis over their useful lives beginning when marketing approval useful life from the other components must be depreciated is obtained. Government grants relating to property, plant and equipment are deducted from the acquisition cost of the asset to which Quantitative and qualitative indications of impairment (primarily they relate. A lease qualifies as a finance lease if it transfers substantially all of the risks and Other intangible assets not yet available for use (such as rewards of ownership of the asset to Sanofi. The depreciable amount of items of property, plant and When there is an internal or external indication of impairment, equipment, net of any residual value, is depreciated on a straight Sanofi estimates the recoverable amount of the asset and line basis over the useful life of the asset. The useful life of an recognizes an impairment loss if the carrying amount of the asset asset is usually equivalent to its economic life. The recoverable amount of the asset is the higher of its fair value less costs to sell or its value in the customary useful lives of property, plant and equipment are use. Fixtures 10 to 20 years In the case of goodwill, estimates of future cash flows are based Machinery and equipment 5 to 15 years on a medium-term strategic plan, an extrapolation of the cash Other 3 to 15 years flows beyond that plan, and a terminal value. In the case of other intangible assets, the period used is based on the economic life Useful lives and residual values of property, plant and equipment of the asset. The effect of any adjustment to useful lives or residual values is recognized prospectively as a change Estimated cash flows are discounted at long-term market interest in accounting estimate. Impairment of property, plant and equipment software and on certain rights are recognized in the relevant and intangible assets classification of expense by function. Reversals of impairment losses charged group) to Assets held for sale or exchange, the carrying against property, plant and equipment, intangible amounts of the asset (or of all the assets and liabilities in the assets, and investments accounted for using the asset group) must be measured in accordance with the equity method applicable standards. At the end of each reporting period, Sanofi assesses whether Subsequent to reclassification to Assets held for sale or events or changes in circumstances indicate that an impairment exchange, the non-current asset (or asset group) is measured at loss recognized in a prior period in respect of an asset (other the lower of carrying amount or fair value less costs to sell, with than goodwill) or an investment accounted for using the equity any write-down recognized by means of an impairment loss. If this is the case, and the recoverable Once a non-current asset has been reclassified as held for sale amount as determined based on the revised estimates exceeds or exchange, it is no longer depreciated or amortized. Impairment of intangible assets, while reversals of impairment the profit or loss generated by a held-for-sale asset group is losses in respect of investments accounted for using the equity reported in a separate line item in the income statement for the method are recognized within the income statement line item current period and for the comparative periods presented, Share of profit/(loss) from investments accounted for using provided that the asset group: the equity method. Impairment losses taken against goodwill fi represents a separate major line of business or geographical are never reversed, unless the goodwill is part of the carrying area of operations; or, amount of an investment accounted for using the equity method. Assets held for sale or exchange and major line of business or geographical area of operations; or, liabilities related to assets held for sale or fi is a subsidiary acquired exclusively with a view to resale. Gains and losses arising from changes in fair value are any depreciation, amortization or revaluation that would have recognized in equity within the statement of comprehensive been recognized if the asset had not been reclassified as held income in the period in which they occur. When such assets for sale, or (b) its recoverable amount at the date of are derecognized, the cumulative gains and losses previously reclassification; recognized in equity are reclassified to profit or loss for the period within the line items Financial income or Financial fi the backlog of depreciation, amortization and impairment not expenses. Financial instruments recognized in profit or loss within the line items Financial income or Financial expenses. The classification used depends on (i) the characteristics of the On initial recognition of an equity investment in an entity not contractual cash flows. Cost ceases to be a representative measure of applied at the time of initial recognition. In such cases, an internal valuation is carried income out, based mainly on peer comparisons. Gains and losses arising from changes in repayments of principal and which are managed with a view to fair value are recognized in equity within the statement of collecting cash flows. The main assets in this category are loans comprehensive income in the period in which they occur. They are presented within the line items Other such instruments are derecognized, the previously-recognized non-current assets, Other current assets, Accounts changes in fair value remain within Other comprehensive receivable and Cash and cash equivalents. These the line item Financial income; financial assets are measured at amortized cost using the effective interest method. Accounts receivable are initially recognized at the amount Such financial instruments are designated as hedging invoiced to the customer. The expected credit loss is estimated effectiveness of the hedging relationship will be assessed, and of collectively for all accounts receivable at each reporting date using the underlying market risk management objective and strategy; an average expected loss rate, determined primarily on the basis (b) the hedged item and the hedging instrument are eligible for of historical credit loss rates. However, that average expected loss hedge accounting; and (c) there is an economic relationship rate may be adjusted if there are indications of a likely significant between the hedged item and the hedging instrument, defined on increase in credit risk. If a receivable is subject to a known credit the basis of a hedge ratio that is consistent with the underlying risk, a specific impairment loss is recognized for that receivable. Impairment losses on accounts receivable are recognized within Selling and general expenses in the income statement. Derivative instruments A fair value hedge is a hedge of the exposure to changes in fair value of an asset, liability or firm commitment that is attributable Derivative instruments that do not qualify for hedge accounting to one or more risk components and could affect profit or loss. That risk is estimated on the basis of cash flows from an asset, liability or highly probable forecast observable, publicly-available statistical data. Changes there must be: in fair value attributable to the ineffective portion of the hedge are (a) a legally enforceable right to offset; and recognized in the income statement within Other operating income for hedges of operating activities, and within Financial (b) the intention either to settle on a net basis, or to realize the income or Financial expenses for hedges of investing or asset and settle the liability simultaneously.
