25 Treg cells have a broad T cell receptor repertoire that can recognize various self and non-self antigens. It has been suggested that the immune system employs Treg

cells to maintain self-tolerance by suppressing the activation and expansion of self-reactive lymphocytes that might otherwise cause autoimmune disease.25 A controlled balance between initiation and down-regulation of the host immune response is vital in maintenance of immune homeostasis. A number of studies have suggested that depletion or reduction of Treg cells leads to enhanced immune responses against various Inhibitors,research,lifescience,medical infectious pathogens including HCV.26,27 A higher Vorinostat purchase proportion of Treg cells was found in patients with chronic HCV infection when compared with successfully treated and/or Inhibitors,research,lifescience,medical healthy controls.26,28–30In vitro depletion of these cells results in increased HCV-specific T cell responsiveness.28,29 Thus, Treg cells appear to suppress the effector response of virus-specific T cells in patients with chronic HCV infection. Treg cells have

been shown to exert their suppressive activity through a number of different pathways. Production of immunoregulatory cytokines has been proposed as a major mechanism by which Treg cells mediate Inhibitors,research,lifescience,medical their function. Treg cell suppressive cytokines that have been described in the literature include transforming growth Inhibitors,research,lifescience,medical factor (TGF)-β, IL-10, and IL-35.31 These molecules have been shown to play a key role in the suppressive activity of Treg cells.31,32 Recently, we and others have identified the fibrinogen-like protein 2 (fgl2) as a putative effector gene of Treg cells and other regulatory T cell subsets, including CD8+CD45RClow T cells, CD8αα+ T cells in the intestine, and CD4−CD8− double negative (DN) T cells.31,33–36 FIBRINOGEN-LIKE PROTEIN 2 (FGL2) FGL2, also known as fibroleukin, was first cloned from cytotoxic T lymphocytes and was classified Inhibitors,research,lifescience,medical as a member of the fibrinogen superfamily due to its homology

(36%) with fibrinogen β and γ chains.37 The fgl2 gene, which has been localized to chromosome 7 and 5 in humans and mice, respectively, is composed of two exons that are separated by one intron. The fgl2 promoter contains cis element consensus sequences for the binding of various transcription factors, including Ets, AP1, Sp1, TCF1, Ikaros, and CEBP.38 The CYTH4 fgl2 gene encodes a protein of 432 amino acids in mice and 439 amino acids in humans. The deduced protein sequence contains a predicted signal peptide, five N-linked glycosylation sites, and conserved cysteine residues. Under non-reducing conditions the molecular mass of the protein is 250–300 kDa, and in reducing condition it is 64–70 kDa, indicating that FGL2 in its natural state forms a tetrameric complex.

2012), and no studies have investigated the neural basis of patients’ loss of self-awareness regarding a complex socioemotional characteristic such as their

capacity to behave empathically toward others. Empathy is a well-characterized, complex social behavior, involving the subjective emotional feelings induced by others’ emotions, the ability to differentiate between the feelings one experiences and the feelings expressed by others, and mental flexibility (Decety and HDAC inhibitor Jackson 2004). Inhibitors,research,lifescience,medical Despite this complexity, healthy individuals are able to represent their own level of empathy fairly accurately, indicating that this information is normally accessible to awareness. Examining the neural substrates of self-awareness for this type of complex behavioral trait could provide information to better dissociate modality-specific from supramodal neural processes underlying self-awareness. Previous neuroimaging studies have

examined impaired self-awareness independent of its directionality, despite the fact that patients can show highly divergent patterns (Michon Inhibitors,research,lifescience,medical et al. 1994; Rankin et al. 2005; Tranel et al. 2010; Zamboni et al. 2010), with some patients overestimating their level of functioning Inhibitors,research,lifescience,medical (“polishers”) and others underestimating it (“tarnishers”). Rather than reflecting a continuum, being overcritical or under critical may reflect divergent pathophysiological processes, thus this should be investigated independently. In this study, we asked whether either overestimation or underestimation of one’s capacity for empathic concern predict specific patterns of focal brain damage in a large sample of neurodegenerative disease patients and healthy older adults. To answer this question, we separated the sample into “polisher” and “tarnisher” Inhibitors,research,lifescience,medical subsamples based on the Inhibitors,research,lifescience,medical subject-informant discrepancy method, using

the Interpersonal Reactivity Index (IRI) (Davis 1983). Within each of these two subsamples, discrepancy measures were then correlated with structural MR images using voxel-based morphometry (VBM) across the whole brain. We also examined the degree to which the anatomy underlying self-awareness of empathic concern corresponds to the neural correlates of empathic concern itself and the neural correlates of affective perspective taking (Davis 1983), a cognitive capacity related Linifanib (ABT-869) to empathic concern (Davis 1983; Sollberger et al. 2012). Materials and Methods Subjects We studied 102 subjects, including 83 patients diagnosed with one of five neurodegenerative diseases and 19 healthy normal controls. Of the 83 patients, 28 patients met the research diagnostic criteria for behavioral variant frontotemporal dementia (bvFTD) (Rascovsky et al. 2011), 16 met criteria for semantic variant primary progressive aphasia (svPPA) (Gorno-Tempini et al. 2011), 4 met criteria for nonfluent variant primary progressive aphasia (nfvPPA) (Gorno-Tempini et al. 2011), 23 met criteria for AD (McKhann et al.

As a result of this increase, services were strained and major gaps between research base and clinical practice were identified with only 50% of children receiving

care that corresponded to guidelines of the American Academy of Child and Adolescent Psychiatry [Hoagwood et al. 2000]. ADHD services around the UK are disparate [Tettenborn et al. 2008] and we would suggest that if audited against the recent NICE Guideline [National Institute for Health and Clinical Excellence, 2008b], the gaps between research base and clinical practice would be at least as high as in the US. Guidelines for ADHD existed in the UK from the beginning of the millennium [Nutt et al. 2007; National Institute for Health and Clinical Excellence, #CDK assay keyword# 2006, 2000; Scottish Intercollegiate Guidelines Inhibitors,research,lifescience,medical Network, 2001; British Psychological Society, 2000] and although the complete NICE Guidelines only arrived late in 2008 [National Institute for Health and Clinical Excellence, 2008a], there was adequate time for implementation. Indeed, the 20 centres

of excellence participating in a multinational study appeared to broadly follow the recommendations set out in national guidelines at the time [Tettenborn et al. 2008], but the same may not translate elsewhere in the country. This disparity in service delivery, in Inhibitors,research,lifescience,medical our opinion mainly a result of underinvestment, could have been the reason behind the disparity in the doses of stimulants for the sample we collected. Furthermore, the lack of clinical pharmacy services to the children and adolescent mental health and community paediatric teams may be a contributing factor as to why Inhibitors,research,lifescience,medical guidelines referring to medicines management are not implemented and/or adhered to. As far as transition is concerned, the experience of UK community paediatricians is

that there are not many Inhibitors,research,lifescience,medical places that their patients can go when they reach adulthood [Marcer et al. 2008]. The suggestion that ADHD is likely to become increasingly important for primary care [Thapar and Thapar, 2002] and that generic teams may take over the care of adults with ADHD cannot be supported not only by our findings, but by the fact that many families of children or adults with ADHD have complex ongoing needs which merit specialist input [Salmon and Kemp, 2002]. The transition period is therefore a landmark process where not only people Ribonucleotide reductase come together, but also different service cultures and therapeutic approaches aiming to meeting the patients’ needs. We would expect that during this process and with clinical pharmacy input, disparities in medicines management would be addressed. Our data also showed that comorbid disorders are common in adults with ADHD. Anxiety disorders, substance abuse disorders and mood disorders are all highly prevalent comorbidities in this patient population, and there is also a significant incidence of antisocial disorder [McGough et al. 2005; Biederman et al. 1993; Shekim et al. 1990].

154 The many antidepressants available are clearly effective for depression but are generally unstudied for PPD. Other considerations

in the selection of an antidepressant are the patient’s tolerability of side effects and the response to a previously prescribed antidepressant. For women with previous episodes of depression, the general guideline is to prescribe the antidepressant used in the previous episode if the patient had a satisfactory response. A major concern about drug therapy for breast-feeding mothers is the effect of medication on the Inhibitors,research,lifescience,medical infant.155 In small studies, amitriptyline, nortriptyline, desipramine, clomipramine, imipramine, sertraline, fluvoxamine, and paroxetine were not detected in quantifiable amounts in infant, plasma and all infants were thriving.156-161 The results are encouraging, but cannot be generalized to all infants exposed Inhibitors,research,lifescience,medical to these medications. Because of the high risk of repeated PPD, the question of prophylactic treatment is important but unanswered. In the only controlled study of an antidepressant administered

as a prophylactic, the Inhibitors,research,lifescience,medical tricyclic antidepressant, nortriptyline, initiated immediately postpartum in nondepressed women at risk of a subsequent PPD, was not better than placebo; 25% of the women in each group had a recurrence of PPD.162 Hormone treatments Sublingual 17β-estradiol (1 mg, 3 to 8 times/day to achieve a serum Integrase inhibitor review concentration of 400 pmol/L) in open treatment for 8 weeks resulted in rapid and Inhibitors,research,lifescience,medical significant improvement for women with severe PPD.163 The women had very low serum estradiol concentrations at the pretreatment baseline (mean = 21.7 pg/mL), but whether the low estradiol levels differed from those of asymptomatic postpartum women could not be determined in the absence of a control group. Women with postpartum psychosis also responded to 17β-estradiol treatment in a similar study conducted by the same researchers.164 Transdermal 17β-estradiol (delivery of 200 μg/day for 6 months) was significantly better than placebo for PPD, meeting criteria for Inhibitors,research,lifescience,medical major depressive

disorder.165 The response occurred in the first month of treatment and was sustained for the 6 months of the randomized, double-blind ADAMTS5 study. The effect on symptoms of a progestin added after 3 months was not reported; endometrial curettage at the end of treatment showed endometrial changes (sic) in three women, which resolved on follow-up. A very small open pilot study administered estrogen immediately after delivery to prevent recurrent PPD.166 A much lower relapse rate than expected in the ensuing year (9% versus an expected 35% to 60% without prophylaxis) suggested the utility of estrogen for high-risk women and supported the hypothesis that PPD may be triggered by rapid changes in the levels of estradiol in vulnerable women.

Cell morphology Early studies of cell morphology found that repeated stress causes atrophy of CA3 pyramidal neurons in the hippocampus, characterized by a decreased number and length of apical dendrites.29,30 More recent studies have shown that pyramidal neurons in the PFC undergo a similar retraction/atrophy of apical dendrites, and a reduction in spine number in response to immobilization stress (Figure 2). 31 Chronic exposure to high levels of exogenous corticosterone, the rodent equivalent of Cortisol, causes a Inhibitors,research,lifescience,medical similar atrophy of hippocampal and PFC neurons.32,33 In contrast to most neurological disorders, in which the structural alterations

and loss of neurons is permanent, the stress-induced atrophy of hippocampal and PFC neurons is SGC-CBP30 nmr reversible. Most notably, removing animals from stress normalizes the dendritic arborization of pyramidal neurons over a period of several weeks.3,32,34 Moreover, chronic administration of certain antidepressants blocks or reverses hippocampal atrophy, Inhibitors,research,lifescience,medical even with continued stress exposure.29,30 This reversibility supports the notion that dendritic alterations represent a type of structural plasticity that has functional consequences. Cell proliferation Inhibitors,research,lifescience,medical In addition to dendritic atrophy, chronic stress decreases the proliferation

of new cells in the adult hippocampus Inhibitors,research,lifescience,medical and PFC. The dentate gyrus of the hippocampus is one of the few regions of the brain that continues to give rise to new neurons in adulthood, in rodents as well as nonhuman primates and humans.35,36 Interestingly, the rate of neurogenesis is influenced by environmental and endocrine factors, and stress is one of the most consistent and robust negative regulators (Figure 2). The proliferation of new neurons is decreased by different types of stress, including restraint, footshock, maternal separation, predator

odor, Inhibitors,research,lifescience,medical psychosocial stress, and sleep deprivation, and by administration of exogenous corticosterone.37 In the PFC the proliferation of glia is decreased by exposure to repeated stress38 or corticosterone treatment.39 Chronic stress also decreases the no number of glial fibrillary acidic protein (GFAP)-positive astrocytes in the hippocampus.40 In contrast, antidepressants increase the proliferation of neurons and glia in the hippocampus and/or PFC, and block or reverse the effects of stress.37,38,41,42 These effects require chronic administration (weeks), consistent with the time course for the therapeutic response to antidepressants. Different classes of antidepressant increase cell proliferation in rats, including serotonin selective transporter inhibitors, norepinephrine selective reuptake inhibitors (NSRIs), and electroconvulsive seizures (ECS),41,43,44 indicating that this is a common target of ADT.

Another rare GSK2656157 supplier seizure disorder with an age of onset intermediate between BFNC and BFIC is benign familial neonatal/infantile convulsions (BFNIC). In BFNIC both neonatal and early infantile onsets of the seizures can be present

in the same family. BFNIC has been shown to be caused by mutations in the voltagegated sodium channel subunit gene SCN2A, a gene that is also discussed as a minor gene for generalized epilepsy with febrile seizures plus (GEFS+).23 Febrile seizures, generalized epilepsy with febrile seizures plus, and Dravet syndrome Febrile seizures are the most common seizure Inhibitors,research,lifescience,medical type in humans; they affect 5 % to 10 % of children under the age of 6 years. In most patients an oligo- or polygenic background rather than a monogenic cause of the seizures is assumed. Inhibitors,research,lifescience,medical Rare families with an apparent autosomal dominant mode of inheritance have been identified, and several putative gene loci described. These tentative

gene locations include FEB1 on chromosome 8q13-q21, FEB2 on 19p, FEB3 on 2q23-q24, FEB4 on 5q14-q15, FEB5 on 6q22-q24, and FEB6 on 18p11.2. In some families febrile seizures may persist beyond Inhibitors,research,lifescience,medical the age of 6 years and/or may be associated with variable afebrile seizures (febrile seizures plus). This probably not so rare syndrome has been named generalized epilepsy with febrile seizures plus (GEFS+). Afebrile seizure types in GEFS+ individuals Inhibitors,research,lifescience,medical include generalized tonoclonic seizures, myoclonic, absence, and atonic seizures, and in some patients also partial seizures.24 The mode of inheritance underlying GEFS+ is still a matter of debate. Although in some families the trait is likely to be autosomal dominant, in others it is probably better described as oligogenic or as a major gene effect. A genetic concept involving more than one gene would also

better Inhibitors,research,lifescience,medical fit to the observed clinical variability in GEFS+. Several different ion channel genes have been implicated in GEFS+ – SCN1B, SCN1A, SCN2A, GABRG2 – but in most families the underlying mutation(s) remain elusive. The first GEFS+ mutation was identified in the SCN1B gene on chromosome all 19q13.1, a gene that encodes an accessory subunit of the voltage gated sodium channel.25 Nevertheless, most of the mutations identified since then were found in the SCN1A gene, one of the genes coding for the major, pore-forming α-subunit of the voltage gated sodium channel.25 These α-subunits are composed of four domains each containing sixTM (TM1-TM6), and the SCN1A mutations arc distributed over the whole length of this large gene.

3 Partial IAB can progress to advanced IAB. Progression time from partial IAB to advanced IAB is shorter than that of the normal P-wave to advanced IAB.20 As was previously thought, advanced IAB may

not exclusively be a complete block.21 Risk Factors and Pathophysiology of Interatrial Block Although the exact pathophysiology of impaired interatrial conduction remains largely unknown, some studies have shown intracellular fibrotic changes and metabolic inclusions in tissue from patients with IAB, particularly in the sarcomere and sarcoplasmic reticulum.22 Generally, coronary artery disease, which contributes to atherosclerotic plaque formation and endothelial injury, might lead Inhibitors,research,lifescience,medical to ischemia-mediated interatrial conduction delay. Thus, cardiovascular risk factors such as diabetes mellitus, hypercholesterolemia, Inhibitors,research,lifescience,medical hypertension, obesity, smoking, physical inactivity, and increasing age have been identified as risk factors for developing IAB.23  There are also studies that have supported this by showing a significant reduction in P-wave duration after angioplasty in patients with acute myocardial infarction.24 Progressive Inhibitors,research,lifescience,medical systemic sclerosis and possibly other autoimmune

disorders may also impair arterial circulation, including in the BB, and lead to the development of IAB.25 Moreover, amyloidosis, lymphoma, and hypertrophic cardiomyopathy involving the atrial septum, especially its superior portion near the BB, can produce similar interatrial conduction delay (table 1).26,27 Table 1 Risk factors and pathophysiology of interatrial block Inhibitors,research,lifescience,medical Increased atrial filling pressure and overstretch of the atrium in conditions such as congestive heart failure, valvular disorders, and hypervolemia

may also cause prolonged conduction or unmask already slowed impulse Selleck Estrogen Receptor inhibitor transmission in the interatrial conduction pathways. Since diuretic therapy for these can reduce P-wave duration, this statement is further supported.28 Inhibitors,research,lifescience,medical Potential Outcomes of Interatrial Block Interatrial Block and Left Atrial Size There are a number of significant concerns in patients with IAB. Patients with IAB tend to have increased LA volumes and diameters. These patients have longer left ventricular Doppler A-wave acceleration times and significantly lower Carnitine dehydrogenase LA stroke volumes, LA ejection fractions, and LA kinetic energy (table 2).29,30 Thus, IAB results in both delayed LA activation and delayed atrial contraction and potentially sets the stage for mistimed LA contraction against a closed or closing mitral valve, which results in a rise in LA pressure, increasing LA wall stress, and subsequent LA dilatation.29,31 IAB patients were matched with those who had normal LA and with a control series that included patients with enlarged LA without IAB.

14–16 CD40, a receptor of the TNF family, plays a critical role in the priming and activation of DCs, and is an attractive target for manipulation to augment antigen presentation. Some investigators have shown that CD40 agonistic monotherapy is sufficient for the induction of an effective immune response.17 Unlike other DC-expressed Inhibitors,research,lifescience,medical receptors that interact with the proinflammatory cytokines or pathogen-associated molecules that DCs encounter throughout the periphery, the DC-expressed CD40 receptor is engaged by CD4+ T-helper cells within the lymph node paracortex through its cognate ligand, CD40L.18,19 This signal enhances the expression of antigen-presenting and costimulatory

molecules, soluble cytokines, and several antiapoptotic molecules, ultimately enabling DCs to activate CTLs. Recent studies have also shown that CD40 stimulation enables DCs to cross-present antigen and overcome peripheral T-cell tolerance. In one ongoing effort to enhance immunogenicity of an autologous DC vaccine, a potent, druginducible CD40

(iCD40) receptor was engineered Inhibitors,research,lifescience,medical that permits temporally controlled, lymphoid-localized, DCspecific activation.20 iCD40 is Galunisertib solubility dmso composed of a membrane-localized Inhibitors,research,lifescience,medical cytoplasmic domain of CD40 fused to drug-binding domains, allowing it to respond to a lipid-permeable, high-affinity dimerizer drug (AP1903) while circumventing ectodomain-dependent negative-feedback mechanisms. These modifications permit prolonged activation of iCD40-expressing DCs in vivo, Inhibitors,research,lifescience,medical resulting in more potent CD8(+) T-cell effector responses, including the preclinical eradication of previously established solid tumors, relative to the standard clinical practice of ex vivo activation (P < .01). In addition, iCD40-mediated DC activation exceeded that achieved by stimulating the full-length, endogenous CD40 receptor both in vitro and in vivo. Because iCD40 is insulated from the extracellular environment and can be activated within the context of an immunologic synapse, iCD40-expressing DCs have a prolonged Inhibitors,research,lifescience,medical lifespan and should lead to more potent vaccines, perhaps even in immune-compromised patients.

Phase I safety Rolziracetam and dose range-finding studies with AP1903 have shown that this dimerizing agent reached effective serum concentrations without generating adverse side effects.20 An open phase I/IIa clinical trial at the University of Texas Health Science Center-Houston is evaluating the intradermal administration of an autologous DC vaccine pulsed with a form of PSMA and transduced with inducible human (ih)-CD40, followed 24 hours later by IV infusion of AP1903, in men with up to one prior systemic regimen for metastatic CRPC (Figure 2). In a related and potentially synergistic approach designed to enhance DC survival, introduction of activated Akt into DCs holds potential for enhancing the efficacy of DC vaccines.

A major disadvantage of MR elastography is the high costs of this technology. Ultrasound elastography, a novel development for assessing tissue stiffness, is considerably more affordable. This technology demonstrates a high applicability for the assessment of muscular tissues located within a few centimetres of the skin (85). While a skilled physician with excellent palpatory skills may be able to detect and assess regions of increased tissue stiffness as well, this technology could be used to document the progression of muscular fibrosis (e.g. when Inhibitors,research,lifescience,medical conducted once per year) in a quantifiable manner (86). However, for assessment of the important fibrotic changes in bronchial

and pericardic tissues in DMD patients, ultrasound elastography is not sufficient. For these purposes, MR elastography Inhibitors,research,lifescience,medical seems more suitable. Myography The development of passive tissue stiffness can also be assessed by biomechanical measurement of the tissue response to a calibrated indentation. Several portable tools are available that claim to measure muscle viscoelastic properties by simulated palpation through the skin (87). The newly developed MyotonPRO seems most promising, as it contains a highly sensitive triaxial BGB324 order accelerometer Inhibitors,research,lifescience,medical and its

basic technology has been successfully tested in conditions such as Parkinson’s disease and stroke (88, 89). While a previous model (Myoton-2) had been examined as a reliable tool for measuring muscle viscoelastic stiffness in healthy adults (90), the reliability of this Inhibitors,research,lifescience,medical improved version still needs to be properly examined, particularly with a wider range of patients and tissue properties, including DMD patients with different disease severities. Only tissues close to the skin can be examined; deeper connective tissues such as from deeper muscles or around the

lungs and heart cannot be reached with this Inhibitors,research,lifescience,medical tool. Advantages of this technology include its portability, affordability and ease of application. Conclusions While muscular dystrophies have mostly been approached as a dysfunction of skeletal myofibres, the accompanying changes in the connective tissue deserve specific interest as well. An increased understanding of the molecular dynamics underlying inflammation, myofibroblast proliferation, many tissue contracture and fibrosis will help in the development of future antifibrotic therapy approaches. A proactive early intervention is recommended, with particular emphasis being given to the pulmonary and pericardial connective tissues. In order to monitor the fibrotic tissue changes, the investigation and further development of appropriate assessment tools seems essential.

With the common phenomenon of aging of Western populations it is of utmost importance to follow time-dependent and age-dependent mortality patterns to predict future needs of Western health systems. Age-specific, gender-specific, and cause-of-death-specific mortality rates were extracted from the statistical abstract of Israel1 and include data for the period of 1975–2010; these are presented in Figure 1, separately for men (A) and women (B). Detailed age-specific causes of death data were available for the year 2009. Data presented were restricted to 5-year age groups starting at age 50, and for cause-specific mortality to the following age groups: 45–54, 55–64, 65–74, 75–84,

and 85+. Causes Inhibitors,research,lifescience,medical of mortality were separated into malignant diseases, acute myocardial infarction, other ischemic heart diseases, other forms of heart diseases, cerebrovascular disease, diabetes mellitus, respiratory diseases, diseases of kidney, infectious diseases, all external causes, signs/symptoms and ill-defined conditions, and all other diseases. Figure Inhibitors,research,lifescience,medical 1 is MK-0518 solubility dmso similar to the one posted on the National Institute of Aging Inhibitors,research,lifescience,medical website and

similar to data across the industrial world. The striking feature of this graph is that aging is a major log scale risk for most diseases, including the major killers: heart disease, cancer, diabetes, and Alzheimer’s. For example, while aging is a 100-fold risk for cardiovascular disease (CVD) according to Figure 1, hypercholesterolemia is known to carry only a

three-fold risk for CVD. For each of the mentioned diseases, aging is a log risk greater than the most Inhibitors,research,lifescience,medical important known risk factor for that disease. Figure 1 Mortality rates for major causes of death, by age, and gender (A: Males; B: Females), Israel 2009. What is the interpretation of this relationship of age and diseases? Based on Figure 1, those of us who investigate the biology of aging have hypothesized that unless we delay aging, we will not have a major impact on age-related Inhibitors,research,lifescience,medical diseases. Even if all cardiovascular disease were to be eliminated, the expected impact would be an additional 2.87 years of life.2 Explaining this in part is that cardiovascular disease can be prevented by drugs, and patients have been saved by interventions such as coronary vessel Bay 11-7085 stenting and by-pass surgery. However, those “saved” patients are likely to die from diabetes, cancer, or Alzheimer’s disease (if not from a second cardiovascular event) within a couple of years.3 This is because we have not addressed the aging part, which continues to put us at risk for other age-related diseases. Unless we delay aging, we will mainly replace one disease with another. Thus, addressing aging overall and not just aiming to prevent a single disease, may lead to a longer health span, and may be more economically cost-effective as well.
