Data concerning the use of angiotensin receptor antagonists have also accumulated. As involves both ischemic and hemorrhagic stroke [283], and summarized in section 4. In this trial combination treat events incidence of cardiovascular events was 31% less ment with perindopril and indapamide lowered systolic with the angiotensin receptor antagonist eprosartan than blood pressure by 12. Overall, if the role of blood cognitive functions have been discussed, with the help pressure reduction appears to be very well established, of a recent meta-analysis [406]. Overall, lowering blood the comparative ef cacy of different antihypertensive pressure was found to slightly improve cognitive perform agents in preventing recurrence of stroke requires to ance and memory, but not to bene t learning capacity. However, in a recent trial on 339 Patients with coronary heart disease often have elevated hypertensive patients, administration of candesartan from blood pressure values or a history of hypertension [622], the rst day after stroke signi cantly and markedly and after a myocardial infarction the risk of a subsequent reduced cumulative 12 months mortality and number of fatal or non-fatal coronary event is greater if blood pressure cardiovascular events [614]. In many instances the randomized studiesonbloodpressuremanagementduring acute stroke are necessary to clarify the matter, and a few are under way [615, 616]. On the other hand, marked blood pressure angiotensin receptor antagonists reduces the inci elevations may be life threatening in these severely com dence of recurrent myocardial infarction and death. There is at present no evidence on the results of trials that have explored the effects of antihy superiority of speci c antihypertensive drugs. In patients with heart failure, if tive properties of the agents rather than the effect of blood hypertension persists after the use of these agents, pressure reduction, to the point that in some of these dihydropiridine calciumantagonistscan beadded, particu studies blood pressure changes were unreported. Evidence is growing, blood pressure changes were reported, almost invariably however, that a signi cant proportion of chronic heart blood pressure was found to be lower in actively treated failure patients, particularly hypertensive and elderly sub patients, so that the relative weight of direct and blood jects, does not present with systolic dysfunction, but rather pressure mediated bene ts cannot be easily unravelled. As to patients with chronic coronary heart disease, the results of four recent placebo-controlled trials have been 7. The increases the risk of cardiovascular morbidity and important role of blood pressure lowering in patients with mortality by approximately 2 to 5 fold with a marked coronary heart disease is supported by a post-hoc analysis increase in the risk of embolic stroke [628]. Hypertensive patients with events decreased steeply in relation to the achieved blood these alterations appear to require intensive antihyper pressure value and was markedly less in patients with tensive therapy. Blood pressure control appears to be blood pressure control versus those without control [478]. The studies mentioned above were both relatively small, and con rmation by large ongoing trials is desirable before Thus it appears that patients with coronary heart disease administration of these agents is rmly recommended for bene t from blood pressure lowering interventions and secondary prevention of atrial brillation. For the time that it does not matter much by which drug blood pressure being, however, angiotensin receptor antagonists may be is reduced; in particular claims that calcium antagonists preferred also in patients with previous episodes of atrial may be dangerous in coronary patients have been dis brillation who require antihypertensive therapy. Obviously, in coronary patients it may be prudent meta-analysis involving published data on primary and to lower blood pressure gradually and to avoid tachycardia.

The efficacy of the In another experimental animal study by application of bioresorbable barrier Schenk et al (1994), similar results were membranes for the treatment of critical size reported. The study aimed to demonstrate the mandibular defects has been further histological healing pattern of bone documented in various experimental models regeneration in membrane-protected in rats and rabbits (Colangelo et al 1993, mandibular osseous defects. In this study, Sandberg et al 1993, Zellin et al 1995, saddle-type defects measuring approximately Lundgren et al 1998). After healing periods of 2 and 4 applied to promote bone regeneration in months, the histological evaluation showed critical size calvarial osseous defects. It was also and underlying soft tissues enhanced bone reported the maturation sequences of the regeneration in experimental calvarial bone regenerated bone closely resembled the pattern defects in rats. On the contrary, incomplete of bone development and growth (Schenk et occlusion of the surrounding intracranial (dura al 1994). Similar observations were following application of a bioresorbable reported when only a pericranial non barrier membrane made of resorbable membrane was used on calvarial polyhydroxybutyrate (Kostopoulos et al defects of rabbits and rats (Hammerle et al 1994a). In addition, the at the lower border of both mandibular rami effect of membrane collapse into the defects of rats, and one side was covered with the was studied and showed that diminished space bioresobable membrane, while the availability for bone regeneration resulted in contralateral side remained uncovered and limited new bone formation (Lundgren et al served as control. The authors concluded that the the membranes results in incomplete bone fill predictability of bone formation depends of the created space due to soft tissue invasion mainly on the presence or absence of barrier 184 Chapter 17 membranes. However, at 12 weeks of healing there was no difference in the amount of newly formed bone Neo-osseogenesis beyond the skeletal among the experimental groups with different envelope membrane porosities. The authors concluded that there is a porosity range within which Several preclinical studies and human osteogenesis beneath the membrane is investigations were carried out to investigate optimal, tissue integration for stability is the possibility of augmenting and/or adequate, and soft connective tissue ingrowth regenerating bone beyond the skeletal is avoided (Zellin & Lindhe 1996). Another envelope (Lundgren et al 1995, Hammerle et study by Lundgren et al (1998) investigated al 1996, Stavropoulos et al 2001, Donos et al the effect of various barrier porosities on 2002a, Donos et al 2002b, Donos et al 2002c, guided bone augmentation.

They demonstrated that new bone of bone formation during the early healing can be produced in areas beyond the skeletal period, but in a less predictable manner. However, after 12 weeks of healing, are a number of factors to be considered when similar amounts of mineralized neogenetic extra-skeletal osteogenesis is to be achieved bone were observed. Also, larger and more rigid suggested that increased porosity of the Teflon membranes of various permeabilities membrane may enhance neogenetic bone and surface characteristics were produced.

The et al (1995) introduced and used prefabricated histological sections showed that the smooth surface titanium dome-shaped specimens harvested before 12 weeks were membranes to create a secluded space adjacent almost entirely comprised of soft tissue, to the bone surface and ensured peripheral whereas specimens with more than 4 months sealing between the borders of the barrier and of healing period were composed of both soft the adjoining bone surface. Similar results were observed as shown 186 Chapter 17 in the previous studies, suggesting that the use presence of uncontrolled diabetes. Diabetes mellitus Osteoporosis Diabetes mellitus is defined as a clinically and genetically heterogeneous group of Osteoporosis is characterized by a metabolic disorders manifested by abnormally reduction in bone mineral density and high levels of blood glucose (Mealey & microarchitectural deterioration of the bone Ocampo 2007).

Where information is available, these elective abortions occurred at gestational weeks 6 to 10. According to the sponsor, no congenital anomalies or any other defects were reported. Seven pregnancies were reported lost to follow-up and 5 pregnancies were reported pending ((outcome unknown). One had unspecified infertility problem and one received an aborticide from her general practitioner. No congenital anomalies or other fetal defects were reported for the 2 live birth. Drug Abuse Potential At the End-of-Phase 2 Meeting, the Division determined that it was not required to have an abuse potential assessment for vortioxetine because vortioxetine was in a class of drugs that we were concerned about abuse potential; and there was no binding at targets that we were concerned about. In addition, there was no evidence in animal studies of abuse potential (for example, self-mutilation or hyperactivity, as per our Pharmacology/Toxicology reviewer Dr. The sponsor asserted that they did not find any evidence of drug-seeking behavior in the clinical studies. Death No deaths occurred during the reporting period for the 120-Day Safety Update. Subdural hematoma was probably caused by head trauma while metrorrhagia is hard to determine. The attending physician considered the event had been due to head trauma although the patient had no memory of such event. Elderly patients may be at greater risk of developing hyponatremia with a serotonergic antidepressant. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which can lead to falls.

The results suggest that intact, raw milk products remain a better source of nutrients and gut health for hyper-sensitive newborns, than most formula product. Lactose, and its interaction with the developing gut microbiota, deserves more attention. Research should continue to better define the nutritive and gut protective factors in natural milk that are of benefit in newborn and growing infants. Impact of nutrient density of formula on nutritional intakes in healthy term infants and the influence of home reconstitution Rigo J. Between 2-16 wks of age, infants were exclusively fed with powder formulas with different protein/energy ratio: 1. Protein intakes calculated from nitrogen determination were compared to that estimated from the labelled values. Discordant results for fat and nitrogen contents (n=6) and formula intakes reported as < 100 or >220ml/kg body weight*day were considered as out of ranges (n=29) and were excluded from the final analysis (n=298). Our study suggests that nutritional density, influenced by home reconstitution, significantly impacts nutrient intake. This needs to be considered in the interpretation of the results of nutritional studies performed in healthy term infants. The multicenter European Childhood Obesity Project was designed to examine the effect of protein supply on anthropometric and metabolic development from infancy throughout childhood. Early nutritional programming of body composition and growth is modulated by protein supply in infancy. The opportunity to reduce body fat mass in early and late childhood by lowering the protein intake of infants offers a new preventive potential of childhood obesity. The reported results do not necessarily reflect the views of the Commission and in no way anticipate to the future policy in this area. Iron and vitamin D deficiency in preterm babies a potential programming link to cardiovascular disease in later life Conlon C. Experimental data suggest that iron and vitamin D deficiency may alter development of the heart, vasculature and metabolic pathways resulting in altered function, thereby potentially leading to cardiovascular disease. The aim of this study was to determine the iron and vitamin D status of preterm babies after hospital discharge. Babies (< 37 weeks gestation) were recruited to the study 4 months after discharge. We conclude that suboptimal micronutrient status in preterm babies 4 months after hospital discharge is common. Optimising nutrition after discharge as well as in hospital may ameliorate the potential cardiovascular disease burden in survivors of preterm birth, a population that is increasing steadily worldwide. Formula-fed infants show higher growth velocities, which has been associated with a higher risk of obesity and type 2 diabetes in later life. Results from several studies indicated, that rapid early growth seems due to a higher protein intake of formula-fed infants compared to breastfed infants. Besides differences in metabolism it has been found that the energetic efficiency (growth per 100 kcal) of breastfed infants is 11% higher than the energetic efficiency of formula fed infants. Less data is available on the importance of formula composi tion for the energetic efficiency of infant formulae. The importance of macronutrient composition or other factors of infant formulae for the utilization efficiency of dietary energy for growth has not been fully elucidated. Results from a randomized controlled trial in 213 healthy term infants until the age of 4 months indicated, that similar to growth velocities in early infancy, the energetic efficiency in formula-fed infants is mainly influenced by the dietary protein / amino acid composition. It is point towards efficiency increasing effects of replacing beta-lactoglobulin by alpha-lactalbumin and the higher content of tryptophan. In respect to growth velocities and energetic efficiency the protein component of infant formulae might be the most important factor of an infant formula. Thus, newly designed formulae with revised protein content and composition should be evaluated in randomized clinical studies including consideration of their energetic efficiency. With an increasing percentage of the global popula tion living in urban areas with high ambient air pollution, and with those living in rural areas turning to alternative solid fuel-burning energy sources in the context of increased energy prices, exposure to air pollution from both outdoor and indoor sources is ubiquitous. It is likely that air pollution has health effects similar to exposure to maternal tobacco smoke, which is similarly composed of mixtures of particles and gases. However, few epidemiologic analyses have examined implications of prenatal air pollution for outcomes beyond the neonatal period. In this talk I will review the global scope of air pollution exposures, components of air pollution, and methods of assessing air pollution exposure in the context of epidemiologic studies. I will discuss existing evidence regarding associations of pollu tion exposure with postnatal growth, obesity, and cardiometabolic risks, and likely mechanisms by which these exposures may act. Accumulating evidence for the obesogenic and endocrine disrupting properties of air pollution has implications for global health. Given a significant interaction between sex and pre-/ postnatal variables, sex stratified analyses were undertaken. In humans, these findings have mostly been explored with respect to weight gain in early child hood. This study examined associations between maternal concentrations of organohalogen contaminants and offspring cardiometabol ic-risk factors at 20 years. Methods: A cohort of 665 Danish pregnant women recruited in 1988-1989 with offspring follow-up in 2008-2009. Other perfluoroalkyl acids were not independently associated with offspring anthro pometry. The aim of this study was to examine associations between organic food consumption during pregnancy and the risk of preeclampsia among Norwegian women. Methods: the present study includes 28, 192 nulliparous women who were recruited to the Norwegian Mother and Child Cohort Study (MoBa) in the years 2002-2007 and had completed a general health questionnaire at gestational week 15 and a food frequency questionnaire at weeks 17-22. Information about preeclampsia was retrieved from the Medical Birth Registry of Norway. The exposure variables were self-reported frequency of organic food consumption in six main food groups. We estimated relative risk as odds ratios and controlled for confounding with multiple logistic regressions. Overall dietary quality was assessed as scores on a healthy food pattern derived by principal component analysis and included as a covariate. No associations with preeclampsia were found for high intake of organic fruit, cereals, eggs or dairy, or an index reflecting total organic consumption. Future studies need to address possible causal relationships underlying the observed association. However there is increasing evidence for adverse health effects of exposure to environmental toxi cants in early life, amongst others on growth and obesity. Animal experiments indicate that environmental toxicants with endocrine disruptive properties may be of special concern. One compel ling study exposed stem cells to organotins and observed increased the number of adipocytes on behalf of the number of skeleton cells. Recently it has been acknowledged that gut microbiota plays a role in early programming. Animal experiments have shown the critical importance of exposure to gut microbiota during early life for optimal development and later functions of diverse organsystems. The more senior the colleague, the less importance he or she placed on the need for anything as mundane as evidence. There is a distinction between these terms; however, they are commonly used interchangeably.

In addition, reduced need for venous access can prevent transfer of an older person away from their current setting to accommodate a higher level of care. In one Canadian study, approximately half of hospitalizations were considered avoidable. Transfer often results in long periods in an unfamiliar and stressful environment for the older person. Other hazards include delirium, hospital-acquired infections, medication side effects, lack of sleep, and rapid loss of muscle strength while bedridden. Frail older persons assessed and treated in their current settings have the opportunity to receive more individualized care and better comfort and end-of-life care. Continuous bed rest or limited ambulation during a hospital stay causes deconditioning and loss of muscle mass and is one of the primary factors for loss of walking independence in hospitalized older adults. Up to 65% of older persons who can walk independently will lose this ability during a hospital stay. Walking during the hospital stay is critical for maintaining this functional ability. Loss of walking independence increases the length of hospital stay, the need for rehabilitation services, the possibility of placement in a nursing home, and the risk for falls both during and after discharge from the hospital. Perceived benefts of restraints are often outweighed by their signifcant potential for harm, including serious complications and even death. Turning an older person q2h is often considered the gold standard implemented in many areas of health care to aid in the avoidance of skin breakdown and pressure injuries. However, there is little evidence to support this particular frequency of repositioning. For older persons at low risk for skin breakdown, this practice may severely impact their quality of life due to sleep deprivation and disruption, leading to delirium, depression and other psychiatric impairments. Excessive repositioning of an older adult may also result in shearing forces that can lead to pressure injuries. Conversely, q2h turning may be inadequate for persons at higher risk for skin breakdown, including those with decreased tissue tolerance and limited mobility. The group consisted of gerontological nursing experts from across Canada, representing a broad range of geographical regions and practice settings. Using a modifed Delphi process for the next two rounds of revision, the group refned and adapted 17 items until it reached consensus on a fnal six-item list. A literature review was conducted to confrm the evidence for these items, and supporting nursing research was added where appropriate.

Yet it can also lead to preventable harms such as urinary tract infection, sepsis and delirium. As a result, extra sheets and pads can contribute to skin breakdown and impede the healing of existing pressure wounds. However, supplemental oxygen does not benefit patients who are short of breath but not hypoxic. Adult incontinence containment products are frequently used for continent patients (especially women) with low mobility. Yet the literature associates their use with multiple adverse outcomes including diminished self-esteem and perceived quality of life, and higher incidence rates of dermatitis, pressure wounds and urinary tract infections. Among older adults, nurses should conduct a thorough assessment to determine the risk of such outcomes before initiating or continuing the use of incontinence containment products. The development of a continence care plan should be a shared decision-making process that includes the known wishes of clients regarding care needs and the perspectives of carers and the health care team. Tube feeding for older adults with advanced dementia offers no benefit over careful feeding assistance related to the outcomes of aspiration pneumonia and the extension of life. Tube feeding may contribute to client discomfort and result in agitation, the use of physical and/or chemical restraint and worsening pressure wounds. People with dementia frequently exhibit responsive behaviors, which are often misinterpreted as aggression, resistance to care and challenging or disruptive behaviours. The benefit of these drugs is limited, however, and they can also cause serious harm including premature death.

The stepwise breakdown of glucose into pyruvate is called glycolysis and occurs in both facultative and obligate aerobes (Figure 1. In fermentation, pyruvate produced by glycolysis is converted to ethanol or lactate (Figure 1. Thus it can be seen that aerobic respiration generates much more energy than anaerobic processes. All higher organisms are obligate aerobes but they can make use of both anaerobic and aerobic processes. Rather, higher organisms must obtain the vast majority of their energy from aerobic respiration, and that is why oxygen is essential for their survival. A total lack of oxygen is referred to as anoxia and rapidly results in cell death. For example, brain damage can result from perhaps as little as three minutes of anoxia. An acute decrease in respired oxygen leads to hypoxia, a situation where oxygen is still delivered to the tissue, but at a rate insufficient to maintain normal cellular processes. The effects of hypoxia depend upon the tissue and the degree and duration of the hypoxic event. For example, the brain is a very aerobic tissue and is exquisitely sensitive to oxygen tension. A more marked drop can result in unconsciousness, progressive depression of the central nervous system, circulatory failure and death. For example, the occlusion of essential blood vessels to the heart (a consequence of atherosclerosis and/or blood clots) results in ischemia. It has been estimated that irreversible myocardial damage can occur after about 20 minutes of ischemia (Sobel (1974)). Exposure to elevated levels of oxygen results in hyperoxia and is deleterious to aerobic microorganisms, plants and animals. Plants show decreased chloroplast development and leaf damage when exposed to oxygen levels above normal. Animals exposed to 100% oxygen show a variety of symptoms depending upon the duration of exposure (Crapo et al. Humans suffer chest soreness, coughing and sore throats following several hours of exposure to pure oxygen. Longer periods cause alveolar damage, edema and permanent irreversible lung damage. Unfortunately, earlier this century unintentional retinal damage and blindness (retrolental fibroplasia) was caused to premature babies when they were maintained on high oxygen levels in their incubators. Fortunately, the level of oxygen to which premature babies are exposed is now more carefully monitored. For example, hyperbaric oxygen is used to treat gangrene because of its toxicity to the obligate anaerobes that cause it. Correct oxygen tension is important to deep sea divers, astronauts, mountain climbers, athletes going from low to high elevations and those undergoing general anesthesia. Oxygen tension is also important in preventing the growth of harmful anaerobic pathogens in canned and bottled foods and beverages. This subject was reviewed recently by Gilbert (1999) so only an overview will be presented here. This breakthrough proposal, however, was initially strongly criticized by researchers who proposed that free radicals were far too reactive to exist in any great quantity in biological materials. These objections were finally laid to rest by the detection of free radicals both in dry biological tissues and in living organisms by electron spin resonance (Commoner et al. His theory proposed that the accumulating irreversible damage to biologically important macromolecules over time led to disease and aging. The superoxide theory of oxygen toxicity, though not completely correct, was responsible for a great deal of experimental work and a better understanding of the field as a whole (reviewed in Halliwell and Gutteridge (1993)). We now know that oxygen mediates its toxic effects through a variety of compounds, not just free radicals, many of which contain other atoms in addition to oxygen. The term radical originally used by chemists referred to an ionic group that had either positive or negative charges associated with it. A free radical is now defined as an atom or molecule that has one or more unpaired electrons. The energy required to cause bond dissociation can be brought about by several different processes, including exposure to heat or electromagnetic radiation, or by chemical reaction. Remember that covalent bonds are formed when two atoms share electrons (usually one from each atom). Radical reactions are much more common in the gas phase and at high temperatures. Readers should be aware that many radical reactions found in the literature (especially chemistry texts) may be for gas phase reactions and are not always applicable to biological systems. Having said this, gas phase free radical chemistry is extremely important to those investigating the effects of atmospheric pollution and cigarette smoke on biological systems. Radicals are produced when high-energy shock waves are used to destroy solid objects. This table summarizes both in vitro and in vivo approaches for free radical production. Like any other chemical, radicals show a broad spectrum of physical and chemical properties. Radicals may share certain common characteristics and can be grouped together as presented in the following table. Unfortunately, as will be readily apparent such classification is not perfect as some radicals can belong to more than one category. A physiological consequence is that radicals play an important role in initiating lipid peroxidation while chain-breaking antioxidants prevent lipid peroxidation by reacting with the radicals forming a much less energetic and less dangerous radical species. Here a single initiation process can lead to the destruction of many poly-unsaturated fatty acid molecules. Unfortunately, not only does this affect membrane fluidity and thus many biochemical processes, but it can also lead to the production of cytotoxic carbonyl breakdown products (Chapter 3). Like any other chain reaction, lipid peroxidation consists of three phases termed a) initiation, b) propagation and c) termination. Biological systems are equipped with several mechanisms designed to prevent lipid peroxidation. Such processes include prevention of radical formation (inhibiting initiation) or 1 Note during disproportionation one species is reduced while the other is oxidized. When placed in an external magnetic field the unpaired electron can align itself, either parallel or antiparallel, to that field. Exposure to electromagnetic radiation of the correct energy will move the electron from the lower energy level to a higher excited one. Thus an absorption spectrum is obtained which can be used for quantitation as well as gaining information about the environment surrounding the free radical (see Halliwell and Gutteridge (1993)). This can be overcome by using spin-trap agents that react with the free radical to produce a longer-lived species that is still paramagnetic (Figure 1. Interestingly, spin traps are also proving to be beneficial in the treatment of diseases thought to involve oxidative stress where they probably act to scavenge damaging free radicals. The ideal spin-trap should readily and specifically react with the radical of interest. It should never decompose during experimentation producing free radicals (see Halliwell and Gutteridge (1993)). The ideal reagent must not be toxic and should readily pass though any biological barrier. This approach is much more versatile than spin trapping as neither the scavenging agent nor the product needs to be a radical. Although often referred to as free radicals, many of the compounds of interest to the field of redox biochemistry are not free radicals and include many non-radical species (Table 1.
