Protein deficiency has also been shown to adversely affect kidney function women's health clinic uvm generic femara 2.5 mg with amex, where it has adverse effects on both glomerular and tubular function (Benabe and Martinez-Moldonado, 1998). Total starvation will result in death in initially normal-weight adults in 60 to 70 days (Allison, 1992). For comparison, protein and energy reserves are much smaller in premature infants, and survival of 1,000-g neonates is only about 5 days (Heird et al. Clinical Assessment of Protein Nutritional Status No single parameter is completely reliable to assess protein nutritional status. Borderline inadequate protein intakes in infants and children are reflected in failure to grow as estimated by length or height (Jelliffe, 1966; Pencharz, 1985). However, weight-height relationships can be distorted by edema and ascites (Corish and Kennedy, 2000). Mid-upper arm parameters such as arm muscle circumference have been used to measure protein status (Young et al. The triceps skinfold is reflective of energy nutritional status while the arm muscle circumference (or diameter) is reflective of protein nutritional status (unless a myopathy or neuropathy is present) (Patrick et al. In addition, urinary creatinine excretion has been used as a reflection of muscle mass (Corish and Kennedy, 2000; Forbes, 1987; Young et al. The most commonly used methods to clinically evaluate protein status measure serum proteins; the strengths and weaknesses of these indicators are summarized in Table 10-6. In practical terms, acute protein depletion is not clinically important as it is rare, while chronic deficiency is important. Serum proteins as shown in Table 10-6 are useful, especially albumin and transferrin (an iron-binding protein). Due to their very short half-lives, prealbumin and retinol binding protein (apart from their dependence on vitamin A status) may reflect more acute protein intake than risk of protein malnutrition (which is a process with an onset of period of 7 to 10 days (Ramsey et al. Hence, albumin and transferrin remain the best measures of protein mal nutrition, but with all of the caveats listed in Table 10-6. In protein malnutrition, the skin becomes thinner and appears dull; the hair first does not grow, then it may fall out or show color changes (Pencharz, 1985). Over a longer period of time, assessment of changes in lean body mass reflects protein nutritional status. The clinical tools most available to assess lean mass are dual emission x-ray absorptiometry and bioelectrical impedance (Pencharz and Azcue, 1996). This section reviews some of the possible indicators used or proposed for use in analyses estimating human protein requirements. Factorial Method the factorial method is based on estimating the nitrogen (obligatory) losses that occur when a person is fed a diet that meets energy needs but is essentially protein free and, when appropriate, also relies on estimates of the amount of nitrogen that is accreted during periods of growth or lost to mothers during lactation. The major losses of nitrogen under most con ditions are in urine and feces, but also include sweat and miscellaneous losses, such as nasal secretions, menstrual losses, or seminal fluid. This is where the factorial method has its greatest weakness, since the relationship between protein intake and nitrogen retention is somewhat curvilinear; the efficiency of nitrogen retention becomes less as the zero balance point is approached (Rand and Young, 1999; Young et al. Additionally, in order to utilize the factorial approach when determining the protein requirement for infants and children, their needs for protein accreted as a result of growth must be added to their maintenance needs. Nitrogen Balance Method this classical method has been viewed by many as theoretically the most satisfactory way of determining the protein requirement. Nitrogen balance is the difference between nitrogen intake and the amount excreted in urine, feces, skin, and miscellaneous losses. As discussed below, nitro gen balance remains the only method that has generated sufficient data for the determination of the total protein (nitrogen) requirement. It is assumed that when needs are met or exceeded adults come into nitrogen balance; when intakes are inadequate, negative nitrogen balance results. In determining total protein (nitrogen) needs, high-quality proteins are utilized as test proteins to prevent negative nitrogen balance resulting from the inadequate intake of a limiting indispensable amino acid. A significant literature exists regarding the methods and procedures to use in deter mining nitrogen balance amount (Manatt and Garcia, 1992; Rand et al. Limitations of the Method the nitrogen balance method does have substantial practical limita tions and problems. First, the rate of urea turnover in adults is slow, so several days of adaptation are required for each level of dietary protein tested to attain a new steady state of nitrogen excretion (Meakins and Jackson, 1996; Rand et al. Second, the execution of accurate nitro gen balance measurements requires very careful attention to all the details of the procedures involved. Since it is easy to overestimate intake and underestimate excretion, falsely positive nitrogen balances may be obtained (Hegsted, 1976). Indeed, an overestimate of nitrogen balance seems con sistent throughout the literature because there are many observations of quite considerable apparent retention of nitrogen in adults (Oddoye and Margen, 1979). A third limitation of the nitrogen balance method is that since the requirement is defined for the individual, and studies rarely provide exactly the amount of protein necessary to produce zero balance, individuals must be studied at several levels of protein intake in the region of the requirement so that estimates of individual requirements can be interpolated (Rand et al. Finally, dermal and miscellaneous losses of nitro gen must be included in the calculation. These are inordinately difficult to measure, and vary with the environmental conditions. In fact, the literature indicates marked (at least twofold) differ ences between studies (Calloway et al. The inclusion of dermal and miscellaneous nitrogen losses can have a significant effect on estimates of amino acid requirements via nitrogen balance, especially in adults (Calloway et al. Statistical Analysis of Nitrogen Balance Data In studies with healthy adults in presumably good nutritional status, it is generally assumed that the protein requirement is achieved when an individual is in zero nitrogen balance. To some extent, this assumption poses problems that may lead to underestimates of the true protein requirement. First, there are sufficient observations of paradoxically high positive nitrogen balances in the literature to imply that when individuals are in measured body nitrogen equilibrium, they are in fact in a small nega tive nitrogen balance (Kopple, 1987). The large majority of the studies have concentrated their measurements of protein adequacy at levels of intake below nitrogen balance and as a result, the intercept of protein intake at zero nitrogen balance is lower than the true intercept as the efficiency of protein utilization decreases as zero balance is reached (Young et al. The empirical solution is to carry out measurements that span nitro gen equilibrium, ideally by using multiple levels of intake in the same individual and interpolating individual requirement levels. Three differ ent interpolation schemes have been proposed, based on (1) a smooth nonlinear model (Hegsted, 1963; Rand and Young, 1999), (2) a two-phase linear model (also called bilinear or breakpoint) (Kurpad et al. Since the physiological response relationship between nitrogen intake and balance is theoretically expected not to be linear, the more complex models (1 and 2 above) would be appropriate bases for arriving at a requirement estimate. Thus, while it is recognized that the first two models above are more realistic biologically, because of the lack of available data the method adopted for this report is to use linear interpolation to estimate the indi vidual requirements (the intakes predicted to result in zero balance) that in turn are used to estimate the distribution of protein requirements. The bilinear model was used to estimate requirements for some of the amino acids; however, estimates of population variability (between individuals) were derived from the analysis of protein requirements. These approaches give somewhat different information about the requirement for the amino acid. Moreover, each method has peculiar theoretical and practical disadvantages, thus the level of consis tency of estimates based on different approaches should be examined. Many explanations have been put forward for the lower results using nitrogen balance methodology, including the fact that excess nonprotein energy may have been used in many nitrogen balance studies (Garza et al. The design of that study allowed for the determination of between individual variance by studying each individual at several levels of lysine intake. In fact, within the large nitrogen balance and amino acid require ment literature, only one other study (Reynolds et al. The reanalysis of the 1956 Jones study produced an estimate of nitrogen equi librium for lysine of 30 mg/kg/d, which is comparable to the values derived by the other methods described below (Rand and Young, 1999). In addition, most of the classic amino acid work using nitrogen balance (Leverton et al. Unfortunately, for infants and children the only data available are those based on nitrogen balance, and considerable uncertainty about the accuracy of the estimates remains. However, recent factorial estimates are in reasonable agreement with the nitrogen balance estimates (Dewey et al. Plasma Amino Acid Response Method this method was the first that focused on the physiology of the indi vidual amino acid (Longnecker and Hause, 1959; Munro, 1970). The reasoning behind this approach is that when the intake of the test amino acid is below its dietary requirement, then its circulating concentration is not only low, but also is relatively insensitive to changes in intake. As intakes of the target amino acid approach the requirement level by increasing the intake of the limiting amino acid, the plasma level of the amino acid starts to increase progressively (see Figure 10-4). A variation on this method involves the examination of the changes in the plasma concentration of the test amino acid as the adult moves from the post absorptive to the fed state post-consumption (Longnecker and Hause, 1961). The main difficulty is that amino acid metabolism is so complex that factors other than the level of amino acid intake, such as gastric emptying time, can influence its concentration (Munro, 1970). This marked a major theoretical advance over the nitrogen balance and plasma amino acid response methods. Thus by analogy to the 2 concentration method, it is assumed that below the requirement the test amino acid is conserved and that there is a low constant oxidation rate, but once the requirement is reached, the oxidation of the test amino acid increases progressively. The most salient problem arises from the reliance on the determination of a breakpoint in the oxidation of the test amino acid. However, at these low dietary intakes, the intake of the infused labeled amino acid becomes significant in relation to dietary intake. This limits its use largely to the branched chain amino acids, phenylalanine, and lysine. Other amino acids, such as threonine and tryptophan, pose particular problems (Zhao et al. A criticism of this method has been that measurements were only made during a short period during which food was given at regular hourly intervals. A later modification of this approach was to infuse the labeled amino acid during a period of fasting followed by a period of hourly meals, thus acknowledging the discontinuous way in which food is normally taken (Young et al. However, although this was an advance on the earlier approach, assumptions still had to be made to extrapolate the results from the short periods to a full day. Thus the 24-hour amino acid balance method was developed to determine the balance of the test amino acid over a 24-hour period that encompassed periods of fasting and feeding. This marked a significant advance in deter mining amino acid requirements because it moved investigations away from the simple study of nitrogen metabolism and allowed, in principle at least, direct measurements of the quantities of the amino acid lost under different nutritional circumstances. This is difficult because amino acid metabolism is compartmentalized and measurements of plasma amino acid labeling likely underestimate true turnover, and hence true oxidative loss, of the amino acid. Although for some amino acids this problem can be circumvented by administering a labeled metabolic product of the amino acid. This probably underlies the fact that to date this method has been applied to only three amino acids: leucine (El-Khoury et al. The reasoning is that when a single indispensable amino acid is provided below its requirement, it acts as the single and primary limitation to the ability to retain other nonlimiting amino acids in body protein. These other amino acids, including the indicator amino acid, are then in nutritional excess and are oxidized (Zello et al. As the intake of the test amino acid is increased, protein retention increases and the oxidation of the indicator amino acid falls until the requirement level of the test amino acid is reached, after which the oxidation of the indicator amino acid is lower and essentially constant. The data are then analyzed to obtain as estimate of the intersection of the constant and linear portions of the relationship (the breakpoint). The first advantage is that the metabolic restrictions of carbon dioxide release apply only to the indicator amino acid. Second, the pool size of the indicator amino acid does not change radically as the intake of the test amino acid is varied. Thus to some extent, potential problems of compart mentation are minimized and, in principle, the method does not require estimates of the turnover of the indicator amino acid. Second, the dependence of the result on the amount of total protein given during the isotope infusion has not been established. Third, the choice of the best indicator is still under study so that data obtained with the method are dependent on the assumption of the general applica bility of the indicator amino acids (phenylalanine and lysine) that have been used most frequently. Classical nitrogen balance studies in humans show that it takes 7 to 10 days for urinary nitrogen to equilibrate in adults put on a protein-free diet (Rand et al. On the other hand, it has been shown that most (about 90 percent) of the adaptation in leucine kinetics is complete in 24 hours (Motil et al. These investigators were unable to show any effect of prior adaptation to these two different phenylalanine intakes on the rates of phenylalanine oxidation at changing phenylalanine intakes, where the adaptation to the test level was about 4 hours. Clearly, from this study, adaptations in amino acid metabolism appear to take place much more quickly than do adaptations in urinary nitrogen excretion and are (at least for leucine [Motil et al. For the regression models to work, ranges of intake (particularly at the low end) have to be fed. In practical terms, this has greatly hampered studies in infants, children, and other vulnerable groups. On the other hand, if the individual only needs to be on a low or even zero intake of the test amino acid for a matter of 8 hours, then it becomes feasible to study indispensable amino acids in these and other vulnerable groups. Such a minimally invasive indicator oxidation model has been devel oped (Bross et al.

This database primarily measures Dietary Fiber intake because isolated Functional Fibers breast cancer logo download femara 2.5 mg for sale, such as pectins and gums minstrel show generic 2.5 mg femara with mastercard, that are used as ingredients represent a very minor amount of the fiber present in foods womens health conference buy genuine femara. For instance womens health 2 coffee purchase 2.5mg femara visa, the fiber content of fat-free ice creams and yogurts womens health 5k order cheapest femara, which contain Func tional Fibers as additives pregnancy test meme purchase cheap femara line, is much less than 1 g/serving and therefore is often labeled as having 0 g of fiber. Although there is a seemingly large gap between current fiber intake and the recommended intake, it is not difficult to consume recommended levels of Total Fiber by choosing foods recommended by the Food Guide Pyramid. Most studies that assess the effect of fiber intake on mineral status have looked at calcium, magnesium, iron, or zinc. Most studies investigating the effects of cereal, vegetable, and fruit fibers on the absorption of calcium in animals and humans have reported no effect on calcium absorption or balance (Spencer et al. However, some studies described a decrease in calcium absorption with ingestion of Dietary Fiber under certain conditions (Knox et al. Slavin and Marlett (1980) found that supplementing the diet with 16 g/d of cellulose resulted in significantly greater fecal excretion of calcium resulting in an average loss of approxi mately 200 mg/d. There was no effect on the apparent absorption of calcium after the provision of 15 g/d of citrus pectin (Sandberg et al. Studies report no differences in magnesium balance with intake of certain Dietary Fibers (Behall et al. Astrup and coworkers (1990) showed no effect of the addition of 30 g/d of plant fiber to a very low energy diet on plasma concentrations of magnesium. There was no effect on the apparent absorption of magnesium after the provision of 15 g/d of citrus pectin (Sandberg et al. Magnesium balance was not significantly altered with the consumption of 16 g/d of cellulose (Slavin and Marlett, 1980). A number of studies have looked at the impact of fiber containing foods, such as cereal fibers, on iron and zinc absorption. These cereals typically contain levels of phytate that are known to impair iron and zinc absorption. Coudray and colleagues (1997) showed no effect of isolated viscous inulin or partly viscous sugar beet fibers on either iron or zinc absorption when compared to a control diet. Metabolic balance studies conducted in adult males who consumed four oat bran muffins daily showed no changes in zinc balance due to the supplementation (Spencer et al. Brune and coworkers (1992) have suggested that the inhibi tory effect of bran on iron absorption is due to its phytate content rather than its Dietary Fiber content. There are limited studies to suggest that chronic high intakes of Dietary Fibers can cause gastrointestinal distress. The con sumption of wheat bran at levels up to 40 g/d did not result in significant increases in gastrointestinal distress compared to a placebo (McRorie et al. For instance, 75 to 80 g/d of Dietary Fiber has been associated with sensations of excessive abdominal fullness and increased flatulence in individuals with pancreatic disease (Dutta and Hlasko, 1985). Furthermore, the consumption of 160 to 200 g/d of unprocessed bran resulted in intestinal obstruction in a woman who was taking an antidepressant (Kang and Doe, 1979). Summary Dietary Fiber can have variable compositions and therefore it is difficult to link a specific fiber with a particular adverse effect, especially when phytate is also often present. It is concluded that as part of an overall healthy diet, a high intake of Dietary Fiber will not produce significant deleterious effects in healthy people. Special Considerations Dietary Fiber is a cause of gastrointestinal distress in people with irritable bowel syndrome. Those who suffer from excess gas production can consume a low gas-producing diet, which is low in dietary fiber (Cummings, 2000). Hazard Identification for Isolated and Synthetic Fibers Unlike Dietary Fiber, it may be possible to concentrate large amounts of Functional Fiber in foods, beverages, and supplements. Since the potential adverse health effects of Functional Fiber are not completely known, they should be evaluated on a case-by-case basis. In addition, projections regard ing the potential contribution of Functional Fiber to daily Total Fiber intake at anticipated patterns of food consumption would be informative. Func tional Fiber, like Dietary Fiber, is not digested by mammalian enzymes and passes into the colon. Thus, like Dietary Fiber, most potentially deleterious effects of Functional Fiber ingestion will be on the interaction with other nutrients in the gastrointestinal tract. Data from human studies on adverse effects of consuming what may be considered as Functional Fibers (if suffi cient data exist to show a potential health benefit) are summarized below under the particular fiber. Chitin and Chitosan Studies on the adverse effects of chitin and chitosan are limited. While the adverse gastrointestinal effects of gums are limited, incidences of moderate to severe degrees of flatulence were reported from a trial in which 4 to 12 g/d of a hydrolyzed guar gum were provided to 16 elderly patients (Patrick et al. Gums such as the exudate gums, gum arabic, and gum tragacanth have been shown to elicit an immune response in mice (Strobel et al. When F-344 rats, known to have a high incidence of neoplastic lesions, were given 0, 8,000, 20,000, or 50,000 ppm doses of fructooligo saccharide, the incidence of pituitary adenomas was 20, 26, 38, and 44 per cent, respectively (Haseman et al. Clevenger and coworkers (1988) reported no difference in the onset of cancer in F-344 rats fed 0, 8,000 (341 to 419 mg/kg/d), 20,000 (854 to 1,045 mg/kg/d), or 50,000 ppm (2,170 to 2,664 mg/kg/d) doses of fructooligosaccharide compared with the controls. Henquin (1988) observed a lack of developmental toxicity when female rats were fed a diet containing 20 per cent fructooligosaccharide during gestation. When pregnant rats were fed diets containing 5, 10, or 20 percent fructooligosaccharide during ges tation, no adverse developmental effects were observed (Sleet and Brightwell, 1990). Fructooligosaccharide has been tested for genotoxicity using a wide range of test doses (0 to 50,000 ppm); the results indicated no genotoxic potential from use of fructooligosaccharide (Clevenger et al. Cramping, bloating, flatulence, and diarrhea was observed at intakes ranging from 14 to 18 g/d of inulin (Davidson and Maki, 1999; Pedersen et al. Consumption of 5 or 15 g/d of fructooligosaccharide produced a gaseous response in healthy men (Alles et al. Briet and coworkers (1995) reported increased flatulence as a result of consuming more than 30 g/d of fructo oligosaccharide, increased bloating at greater than 40 g/d, and cramps and diarrhea at 50 g/d. Increased flatulence and bloating were observed when 10 g/d of fructooligosaccharide was consumed (Stone-Dorshow and Levitt, 1987). The role carbohydrate malabsorption plays in the onset of diarrhea most likely depends upon the balance between the osmotic force of the carbohydrate and the capacity of the colon to remove the carbohydrate via bacterial fermentation. In order to evaluate the significance of osmolarity, Clausen and coworkers (1998) compared the severity of diarrhea after consumption of fructooligosaccharide and lactulose, both of which are nonabsorbable carbohydrates. Although both carbohydrates are fermented by colonic microflora, they differ in osmolarity. In a crossover design, 12 individuals were given fructooligosaccharide or lactulose in increasing doses of 0, 20, 40, 80, and 160 g/d. The increase in fecal volume measured as a function of the dose administered was twice as high for lactulose as for fructooligosaccharide; however, there was substantial interindividual varia tion in the response. The researchers concluded that fecal volume in carbohydrate-induced diarrhea is proportional to the osmotic force of the malabsorbed saccharide, even though most is degraded by colonic bacteria (Clausen et al. Anaphylaxis was observed following the intravenous administration of inulin for determining the glomerular filtration rate (Chandra and Barron, 2002). A skin-pricking test revealed hypersensitivity to each of the above foods or ingredients (Gay-Crosier et al. Pectin Pectin has been shown to have a negligible effect on zinc retention in humans (Lei et al. Polydextrose Polydextrose has showed no reproductive toxicity, teratology, muta genicity, genotoxicity, or carcinogenesis in experimental animals (Burdock and Flamm, 1999). In humans, no reports of abdominal cramping or diarrhea were reported in men and women who were given up to 12 g/d of polydextrose (Jie et al. Furthermore, there were no complaints of abdominal distress with the consumption of 30 g/d of polydextrose (Achour et al. However, flatulence and gas-related problems were reported following the intake of 30 g/d of polydextrose (Tomlin and Read, 1988). Diarrhea was reported with the consumption of 15 g/d of poly dextrose; however, this symptom ceased after 1 month of intake (Saku et al. In a meta-analysis of eight studies regarding psyllium intake, the authors found that psyllium was well tolerated and safe (Anderson et al. Furthermore, an elderly woman who was given 2 tbs of a psyllium-based laxative three times daily suffered from small bowel obstruction (Berman and Schultz, 1980). Thus, psyllium generally does not cause gastrointestinal distress provided adequate amounts of water are consumed. In the European Center Prevention Organization Study, psyllium (Functional Fiber) was provided at a level of 3. Patients (n = 655) with a history of colon adenomas were randomly assigned to one of three treatment groups: 2 g/d of calcium, 3. The adjusted odds ratio for colon adenoma recur rence for the psyllium fiber intervention was 1. The authors concluded that supplementation with psyllium may have adverse effects on colon adenoma recurrence. Several reports of anaphylaxis have been reported following the ingestion of psyllium-containing cereals (Drake et al. Symptoms of asthma have also been reported in individuals exposed to psyllium powder (Busse and Schoenwetter, 1975). Summary While occasional adverse gastrointestinal symptoms are observed when consuming some of the isolated or synthetic fibers, serious chronic adverse effects have not been observed. Furthermore, due to the bulky nature of fibers, excess consumption is likely to be self-limiting. There also needs to be increased validation of intermediate markers, such as polyp recurrence, and assess ment of functional markers.

Augmentation with a second-generation antipsy no difference in remission between changing to either chotic agent was significantly more effective than placebo mirtazapine or nortriptyline at the third step. These previous studies were either small in size tidepressant medication trials, this meta-analysis showed or, in the vast majority of instances, were neither random no differences in response or remission rates among the in ized nor blinded. To date, few data from controlled studies though results from these trials have been variable, up to address the longer term efficacy or side effects of combin 50% of patients have been found to respond.

The cumulative probability of subsequent trial found that continuation pharmacother recurrence through the first 12 months of the maintenance apy with lithium plus nortriptyline (N=94) was comparable phase treatment was 23. One study found that among patients who may effectively lengthen the interepisode interval for responded to acute treatment with cognitive therapy, those patients with recurrent depression who do not receive who continued this treatment over 2 years had lower re medication (289, 314, 513, 1056). Results from a series of studies (365, 367, medication plus treatment as usual (368, 497, 1160). A (497) studied 187 patients with recurrent major depressive 6-year follow-up of patients treated with medication and disorder who were currently in remission. Research on cognitive therapy has explored with the number of previous depressive episodes. Some results suggest that the combination of an more than three booster sessions over that year, had a lower tidepressant medications plus psychotherapy may be rate of relapse (31%) than those withdrawn from medica additionally effective in preventing relapse over treatment tion (76%). They also exhibited no greater likelihood of with single modalities (314, 365, 506, 515, 516). However, depressive relapse than patients who continued pharma in individuals older than age 70 years who received main cotherapy (47%), suggesting possible lasting benefits of tenance treatment with paroxetine and clinical manage cognitive therapy. It would be important to determine the compo there are still many unanswered questions about optimiz nents of specific psychotherapies that are responsible for ing and individualizing treatment. The following areas re efficacy, the patient-specific factors that moderate the ef quire additional study. In the frequency of psychotherapy for particular patient sub nearer term, science can focus on predictors of benefit and groups, types of psychotherapy, or phases of depression adverse effects of specific treatments. Outcome measures of psychotherapy studies depression or moderators of treatment response may be should not only examine acute symptom response but also found through genomics, proteomics, physiological mark whether psychotherapies have enduring, protective ef ers, personality traits, personal experiences, co-occurring fects in averting relapse and recurrence of depression after conditions, or clusters of specific depressive symptoms. A manual-based model of psycho Culture, race, and ethnicity merit study in shaping treat dynamic therapy for depression (1170) may be helpful in ment selection and predicting response and side effects. Even if science were to offer perfect and personalized Strategies for sequencing psychotherapy in the overall treatments for depression, patients must be able to gain treatment of major depressive disorder and for combining access to care and adhere to recommended interventions. Re Much work remains to be done on medication inter search should also consider the cost-effectiveness of care vention in depression. We should address the comparative and effects of treatment on functioning and quality of life. More research is required on the continuation and particular treatments or combinations of treatments have maintenance phases.
