Recent population surveys Report of the Education indicate that Manitobans may be at higher Working Group risk for Type 2 diabetes due to high dietary fat intakes and increased body weights. Patient and Considerable evidence supports a professional education allow the proper relationship between physical inactivity and implementation of general dietary and diabetes. This promotes the relationship emerged from the final goals of treatment: the day-to-day observations that societies that had well-being of the person with diabetes and discontinued their traditional lifestyles the preservation of life with the least risk experienced major increases in the of developing long-term problems. Stress reduction provides provide knowledge and increase awareness emotional stability and well-being, and of the behaviours and skills necessary to reduces the risk for diabetes.

Continuing education diabetes, its incidence and prevalence, and opportunities must be available to its distribution in Manitoba. Comprehensive care is fundamental to the The Care Working Group integrated prevention and/or delay of both the three themes into the development of their short-term and long-term complications of recommendations: diabetes. The goal of the Manitoba Diabetes September of 1998 have also conclusively Care Recommendations is to provide shown that optimal control of blood standardization of care and education glucose in Type 2 diabetes significantly throughout the province.

Given the different funding developed recommendations about sources for basic and clinical research, they communication networks throughout the should not be considered to be in province and among the various members competition with one another. An inventory of current and published Report of the Research research (Appendix D) was established and Working Group reviewed. Background Research is vital to understanding the nature The Research Working Group integrated of diabetes, reducing the burden of the four themes into the development of their disease and its complications, improving the recommendations: quality of life of Manitobans with diabetes Research Funding and reducing its economic and social costs. It is not easy to determine the total The ultimate success of our battle against amount of research funding for diabetes diabetes lies with research at all levels. There is promotion and support of research activities no central registry of projects, multiple must be a priority of this Strategy. Some research projects have no designated funding source other than the salaries of There are three types of diabetes research: the academic or government scientists • Basic: Refers to laboratory studies, animal involved in the research. One measure of the relating to diagnosis, prevention, magnitude of research funding support is treatment and outcomes of the disease. Table 3 summarizes the funds awarded to the University of Manitoba by various agencies during the period 1989-1997. Industry $ 153,693 Juvenile Diabetes Foundation $ 149,305 The vast majority of diabetes-related Manitoba Health Research research at the University of Manitoba is Council $ 75,745 carried out in the Faculty of Medicine but Canadian Kidney Foundation $ 43,000 other faculties involved have included Children’s Hospital/Health Dentistry, Nursing, Human Ecology and Sciences Centre Foundations $ 35,000 Physical Education. Manitoba Medical Services Foundation $ 30,000 Information on industry grants is incomplete Total $2,585,296 and not easily obtained. These funds are often administered through the hospital rather than the University, so there is no centralized accounting for these grants. Collaboration and Networks Diabetes researchers can not and should A Provincial Centre for Diabetes Research not work in isolation. Most diabetes (modeled, for example, on the Centre on researchers are already part of an informal Aging at the University of Manitoba) would network of colleagues and collaborators, provide dedicated and long-term nationally and internationally. It would attract Within the province, examples of the formal financial contributions by industry and linkages between researchers include the government and encourage the recruitment following: of high-calibre researchers to the university. It could also play a role in research groups formally recognized by province-wide recruitment of participants in the Faculty in its structural reorganization. Community-Based Diabetes • Health Canada is currently considering a Research and Ethics proposal for a Centre for Innovation in Research should involve the full Aboriginal Diabetes Care, Education and participation of communities, not only with Research to be based in Peguis First community members consenting as Nation. This National Centre would research subjects, but also involving them in consolidate and promote community-based deciding on priorities and playing an active research on diabetes interventions in the role in designing and executing the projects. The result would be a move away from the traditional model of research on While the majority of diabetes researchers communities towards research for are university-based academic researchers, communities and ultimately, research by it should be recognized that research is not communities. There with specific gains beyond contributing to are limited opportunities for practice-based an increase in the knowledge base. Several improve understanding of the research models exist, for example, the one process and scientific method. This concern developed by the Kahnawake Diabetes is jointly shared by the Education Working Education Project in Quebec. Existing guidelines and structures for ethical The media do not always provide accurate approval developed for basic biomedical accounts of research and researchers are and clinical research are not entirely suitable not always proficient in explaining their or appropriate for community-based work in comprehensible language.

Technical Expert Panel input 2-4 0–12 interval aA 30% greater improvement compared with placebo in composite symptom/rescue medication use scores was proposed as minimally clinically meaningful discount 10 mg singulair overnight delivery. We initially assessed the evidence to determine whether one treatment was therapeutically superior to another and found that order singulair online pills, for many comparisons purchase singulair 4 mg on line, the evidence suggested equivalence of the treatments compared. Equivalence: Treatments demonstrated comparable effectiveness, either for symptom improvement or harm avoidance. Two reviewers independently evaluated the strength of evidence, and agreement was reached through discussion and consensus when necessary. Four main domains were assessed: risk of bias, consistency, directness, and precision. Further research is very unlikely to change our confidence in the estimate of effect. Further research may change our confidence in the estimate of effect and may change the estimate. Further research is likely to change the confidence in the estimate of effect and is likely to change the estimate. Results Overview Of the 4,513 records identified through the literature search, 4,458 were excluded during screening. Four records were identified through gray literature and hand searching of bibliographies. However, this trial was not included because quality assessment was not possible without the published report. No observational studies, systematic reviews, or meta-analyses that met our inclusion criteria were identified. For most outcomes, evidence was insufficient to form any comparative effectiveness conclusion. In five comparisons, we found evidence for comparable effectiveness (equivalence) of treatments for at least one outcome (rows 5, 6, 8, 11, and 12 in Table B). We found evidence for superior effectiveness of one treatment over another for one outcome in each of two comparisons (row 5 and row 9 in Table B). For seven comparisons, trials included only a small proportion of the drugs in each class (rows 1, 6, 8, 9, 10, 11, and 12 in Table B). Summary of findings and strength of evidence for effectiveness in 13 treatment comparisons: Key Question 1—adults and adolescents a Asthma Comparison Representation Nasal Symptoms Eye Symptoms Quality of Life Symptoms 1. For all other outcomes, “insufficient” indicates insufficient evidence for conclusions of superiority; equivalence was not assessed. To avoid insomnia, moderate-strength evidence supported the use of oral selective antihistamine rather than either monotherapy with an oral decongestant or combination therapy with oral selective antihistamine plus oral decongestant. For all other comparisons, evidence to indicate superior harms avoidance with one treatment compared with another was insufficient or lacking. Two trials that compared oral selective antihistamine with oral nonselective antihistamine met our inclusion criteria. Evidence on nasal and eye symptoms and on harms was insufficient based on these trials, which had high risk of bias and reported imprecise results. No observational studies, systematic reviews, or meta-analyses met the required inclusion criteria. Summary of findings and strength of evidence for harms in 13 treatment comparisons: Key Question 2—adults and adolescents Comparison a a 1. Note: Entries indicate comparative efficacy conclusions supported by the evidence or insufficient evidence to form a conclusion. Comparative Effectiveness and Adverse Effects of Treatments in Adults and Adolescents 12 Years of Age or Older We did not find evidence that any single treatment demonstrated both greater effectiveness and lower risk of harms. Table D shows the four comparisons for which there was evidence to support a conclusion of superiority, either for effectiveness or for harms avoidance. Moderate- strength evidence supported the use of oral selective antihistamine to avoid insomnia associated with sympathomimetic decongestant at approximately 2 weeks (row 1 and row 4), but evidence was insufficient to draw any conclusion about comparative effectiveness between treatments. Comparison of efficacy and harms findings for four treatment comparisons a Comparison Representation Efficacy Outcome Harms Outcome b 1. Additional findings for comparative effectiveness in adults and adolescents were as follows. Because physiologic changes of pregnancy alter drug disposition, generalization of findings from nonpregnant populations to pregnant women requires knowledge of the magnitude and direction of these changes. No observational studies, systematic reviews, or meta-analyses met the required inclusion criteria. The evidence for effectiveness and for harms was insufficient to form any conclusion about oral selective and oral nonselective antihistamine for the treatment of nasal or eye symptoms in children younger than 12 years of age (mean age, 9 years; range, 4 to 12 years). This finding was based on studies of 20 percent of oral selective antihistamines and 9 percent of oral nonselective antihistamines used to treat children. As with harms outcomes, a finding of insufficient evidence to support a conclusion of superiority of one treatment over the other does not imply equivalence of the treatments. Each provided a description of the literature search, inclusion and exclusion criteria for identified trials, and quality assessments of included trials. In all cases, discordant conclusions could be attributed to differences in inclusion criteria for trials reviewed. For five of eight discordant conclusions, other systematic reviews formed conclusions about comparative effectiveness or harms and we found insufficient evidence to do so. The other three discordant conclusions involved intranasal corticosteroid alone (vs. We concluded that there was comparable effectiveness (equivalence) of the treatments compared, and other systematic reviews concluded that there was comparative superiority of intranasal corticosteroid. Limitations of Current Review and Evidence Base To narrow the scope of this project to a manageable size, we made several decisions at the start that had downstream consequences. Given the current state of transition between classification schemes for allergic rhinitis, use of the original scheme may have excluded some trials. We decided to pick one disease to study and then find studies similar enough to compare results. Introducing studies of allergic rhinitis classified according to the newer scheme may have added to the variability of included studies. It is hoped that we selected and found evidence to assess comparisons that are meaningful to users of this report. We excluded trials of one drug versus a placebo and focused on direct comparisons only. This decision was based on feasibility concerns, given the large scope of the project and time constraints. Harms assessment was limited by the absence of placebo groups, which can inform adverse event reporting particularly. For the comparison of oral selective antihistamine with oral nonselective antihistamine, in particular, this significantly reduced the number of included trials. Our minimum 2-week duration excluded examination of other treatment features that may be important to patients—for example, onset of action and harms associated with shorter exposure. Trials of less than 2 weeks’ duration often did not replicate natural methods of exposure to airborne allergens (i.
Of 42 countries in the African Region that reported on testing order singulair amex, the percentage of cases tested was less than 20% in 21 countries purchase singulair 5 mg free shipping. Most countries with 80 South-East Asia high rates of testing have had a policy of confrming every malaria Western Pacific case for several years cheap 5mg singulair mastercard; some countries have recently expanded the 60 South-East Asia availability of diagnostic testing with some success (Boxes 5. The number of conﬁrmed malaria cases rose from 53 000 in 2007 to 175 000 in 2009 because of the Figure Box 5. The number of recorded deaths from malaria has fallen ranging from very low in the plains along the Mekong River and in from 350 in 2000 to 5 in 2009.

Treatment outlets comprise any place where patients seek treatment for malaria such as hospitals, health centres, health posts, pharmacies, shops or kiosks. However, there is a wide use of less effective treatments to which malaria parasites are scatter of points, with most lying below the line that defnes where becoming increasingly resistant. Thus it appears that for many of oral artemisinin monotherapies, thereby delaying the onset of countries the number of children receiving antimalarial medicines is resistance to that drug and preserving its effectiveness. However, whereas almost all cases received the initiative to other malaria-endemic countries is envisaged.

The need for antimalarial medicines will depend on receiving an antimalarial in the private sector with that observed for diagnostic practices and the treatment policies existing within a the public sector. In high burden African countries tion of those not treated in a health facility have access to antima- most treatment policies allow for antimalarial medicines to be given larial medicines at home. The use of antimalarial medicines is recorded children attending private sector facilities also appear less likely to in household surveys but information on diagnostic testing, and 7. A high correlation is observed whether or not an adjustment is made for therefore treatment needs, is not available in most of these surveys. Hence, the lower rate of treatment utilization among those who are not treated in a health The lower proportion of children who received an antimalarial when facility may be appropriate. However, from the information available treated at home may be appropriate if fevers are transient, or consid- there is no assurance that children who receive antimalarial medicines ered by caregivers to be less serious and not requiring medication, but are those who are parasite-positive and in need of treatment. In addition household survey data are restricted that 87% of suspected malaria cases attending public health to children under 5, whereas data on the percentage of suspected facilities received a parasitological test, of which 48% tested malaria cases that are test positive are usually only available for all positive. Moreover the analysis does not consider public health facilities in Rwanda required an antimalarial (13% whether health workers withheld a test because other symptoms who were not tested plus 87% x 48% who tested positive). It children receiving an antimalarial is appropriate for those treated in therefore appears that the percentage of children receiving an private sector facilities or those who are not treated in any health antimalarial medicine compared to those needing one was 57% facility. The percentage of malaria among those who do not seek treatment is also required; patients with suspected malaria who received a parasitological test some insight could be derived from malaria indicator surveys that increased to 100% while only 22% were test positive. Unfortunately datasets from many percentage of patients attending public sector facilities that needed of such surveys are not readily available for analysis. The percentage of children attending public facilities who received an Rwanda 2005 % of cases in public sector antimalarial was recorded as 16%. The percentage of need that 20 6 0 had been fulﬁlled had therefore increased to 75% (16%/22%) Received parasitological test despite the overall percentage of children receiving an antimalarial having decreased. This is largely because the percentage of Need antimalarial (positive test suspected malaria cases testing positive for malaria had dropped or untested) from 48% to 22% owing to decreasing incidence of malaria as a Received result of control activities. In 2007–2009, the percentage of women who received two For 22 of the 35 high-burden countries, consistent data were doses of treatment during pregnancy ranged from 2. A high level of treatment international agencies have de-listed oral artemisinin-based mono- failure for this combination was also observed in four Indonesian therapy medicines from their product catalogues.

Based on their experience, a generic series of actions has been developed to remove oral artemisinin-based monotherapy medicines from the market (Box 5.

Proposed minimal standards for the genus Mycobac- terium and for the description of new slowly growing Mycobacterium Species discount generic singulair uk. Impact of new technologies on Mycobacterium tuberculo- sis genomics A new wave in the analysis of the physiological secrets of microorganisms started more than a decade ago with the reading of the first complete genome sequence, corresponding to the bacterium Haemophilus influenzae (Fleishman 1995). Nowa- days, the accessibility to hundreds of bacterial genome sequences has changed our way of studying the bacterial world, including bacterial pathogens such as M. A quick search in PubMed, limiting results to the last 10 years, showed more than 27,000 papers devoted to “omics” issues: more than three thousand concerning bacteria, and almost three hundred concerning Mycobacterium tuberculosis. Up to five different “omics” methodologies have been described so far, all concerning the global study of the target organism, analyzing all its genes, transcriptional products, proteins, etc. Integration of data derived from the several “omics” by bioinformatics will probably allow a rational insight into M. The sequence of the genome, and its comparison to sequences of other microorganisms reported in several databases, allowed the as- signation of precise functions to 40 % of the predicted proteins and the identifica- tion of 44 % of orthologues (genes with very similar functions in a different spe- cies), leaving 16 % as unique unknown proteins. The elucidation of complete genome sequences and the development of microar- ray-based comparative genomics have been powerful tools in the progress of new areas by the application of robotics to basic molecular biology. Comparative ge- nomics and genomic tools have also been used to identify factors associated with the pathogenicity of M. Moreover, these tools allowed a de- scription of the evolutionary scenario of the genus (see Chapter 2). A major barrier for genomic studies has been the great number of genes with unknown function that have been identified. The elucidation of protein function was possible with the global analysis of bacterial proteins, giving insights into the functional role of several so far unknown proteins. Thanks to the joint contributions of biochemical techniques and mass spectrometry, up to 1,044 non- redundant proteins were reported in different cellular fractions (Mawuenyega 2005). Genomics and other molecular tools allowed studies on gene expression and regu- lation, which were unthinkable years ago. Understanding how the bacillus regulates its different genes according to environmental changes will probably lead to the comprehension of many interesting aspects of M. This chapter will address the general basics, as well as the state-of-the-art ge- nomics, transcriptomics and proteomics in relation to M. Finally, a general overview will be made on lipids, the most peculiar metabolites of this bac- terium. Expectations were generated on the elucidation of some unique characteristics of the biology of the tubercle bacillus, such as its characteristic slow growth, the nature of its complex cell wall, certain genes related to its virulence and persistence, and the apparent stability of its genome. In turn, the few genes with particularly low (< 50 %) G+C content are those coding for transmembrane proteins or polyketide synthases. This deviation to low G+C content is believed to be a consequence of the required hydrophobic amino acids, essential in any trans- membrane domain, that are coded by low G+C content codons. The posses- sion of a single rrn operon in a position relatively distant from oriC has been pos- tulated to be a factor contributing to the slow growth phenotype of the tubercle bacillus (Brosch 2000a). Another 32 different insertion sequences were found, of which seven belonged to the 13E12 family of repetitive sequences; the other insertion sequences had not been described in other organisms (Cole 1998b). Two prophages were detected in the genome sequence; both are similar in length and also similarly organized. The second prophage, PhiRv2 has proven to be much more stable, with less variability among strains (Cole 1999). A bias in the overall orientation of genes with respect to the direction of replication was also found. It was also found that the number of genes that arose by duplication is similar to the number seen in E. The lack of divergence of duplicated genes is consistent with the hypothesis of a recent evolutionary descent or a recent bottleneck in my- cobacterial evolution (Brosch 2002, Sreevatsan 1997, see chapter 2). This flexibility is useful for survival in the changing environments within the human host that range from high oxygen tension in the lung alveolus to microaerophilic/anaerobic condi- tions within the tuberculous granuloma. In total, there are genes encoding for 250 distinct enzymes involved in fatty acid metabolism, compared to only 50 in the genome of E. These proteins are believed to play an important role in survival and multiplication of mycobacteria in different environments (Marri 2006). Pro- teins in this class contain multiple tandem repetitions of the motif Gly-Gly-Ala, hence, their glycine concentration is superior to 50 %. This gene encodes the enzyme in charge of removing oxidized guanines whose incorporation during repli- cation causes base-pair mismatching (Mizrahi 1998, Cole 1999). With the aim of making the information publicly available and the search and analysis of information easier, the Pasteur Institute (http://www. This database is freely available for use on the Internet and is known as the Tuberculist Web Server http://genolist. As more information was generated, databases grew bigger, more experimental information became available, and better and more accurate algorithms for gene identification and prediction were released. The letter C was not included since it usually stands for “comple- mentary”, which means that the gene is located in the complementary strand. As expected, the classes that exhibited the greatest numbers of changes were the un- known category and the conserved hypothetical category (Table 4-1). The re- annotation of the genome sequence allowed the identification of four sequencing errors making the current sequence size change from 4,411,529 to 4,411,532 bp (Camus 2002). Comparative genomics In recent times, new technologies have been developed at an overwhelming pace, in particular those related to sequencing and tools for genome sequence data man- agement, storage and analysis. As of April 2007, 484 microbial genomes have been finished and projects are underway aimed at the sequencing of other 1,155 micro- organisms (http://www. Mycobacteria are not an exception in this titanic genome-sequencing race; since 1998, when the first myco- bacterial genome sequence was published (Cole 1998a); many genome projects have been initiated. Until April 2007, 34 projects on the genome sequencing of different mycobacterial species are finished or in-process. For this reason, these are the strains that have been used as reference strains for comparative genomics both in vitro and in silico. The next step in comparative genomics was the use of genomic subtractive hybridi- zation or bacteria artificial chromosome hybridization for the identification of re- gions of difference among the strains under analysis (Mahairas 1996, Gordon 1999). As a result, they identified 10 regions of difference, including the three previously described (Mahairas 1996). Until 2002, most studies concerning comparative genomics were based on differ- ences among the strain type M. Some excellent reviews are available on comparative genomics, made before the publication of the second M. This strain was considered to be highly transmissible and virulent for human beings (Fleischmann 2002).

Inadequate training in risky use and addiction A related barrier to screening for risky use of means that many physicians do not recognize addictive substances and providing brief these conditions in their patients, do not believe interventions is the lack of effective and that substance-related interventions are appropriate specialty treatment services 203 effective, are unaware of what do with a available for referral when addiction is 211 patient who screens positive for risky use or identified. Although having more trained addiction or are uninformed about effective addiction physician specialists is critical to resources to which they could refer patients in providing care for those with severe forms of the need of more in-depth assessment or of specialty disease, the lack of such specialty providers is 204 treatment. Neither is it a legitimate Most schools lack employees or consulting reason for general health care professionals to be personnel with the necessary training and unprepared to provide addiction treatment that resources for identifying students who engage in does not require specialty care. These services risky use of addictive substances and attaining are designed to be provided in non-specialty care appropriate intervention services for those settings, along with some forms of assessment 205 students who need them. The real barrier survey of school personnel conducted for its in this case remains the lack of knowledge about 2011 report, Adolescent Substance Use: risky use and addiction and insufficient training America’s #1 Public Health Problem, found that in addressing these issues among health three-fourths of teachers are unable to identify a professionals.

Most schools have not set up partnerships with health care Because the general model in medicine today providers trained in conducting screening or (which is reflected or driven by insurance early interventions to refer students who engage reimbursement structures) is procedure-oriented in risky use nor do they have links to appropriate and reactive more than preventive, and because treatment programs to which they refer students insurance coverage for screening and brief 208 * with addiction. Too often, state substance increases the likelihood that risky use policymakers or administrators of these will not be adequately detected or that programs fail to understand how risky use and interventions will fail to reduce risky use across addiction impede progress in achieving their the board. Only a few screening instruments have The priorities of protecting patient undergone rigorous scientific examination to confidentiality and maintaining an amicable and determine their reliability, validity, sensitivity trusting doctor-patient relationship also may and specificity--key elements determining the § 221 impede health professionals’ implementation of effectiveness of such instruments. While existing federal than using objective and standardized measures * regulations protect the privacy of patients of risky use and risk for addiction, many of the receiving addiction-related services in settings more commonly-used screening instruments that are federally assisted and that are primary determine risk by relying on respondents’ providers of these services, the regulations do subjective reports of their own reactions to their 218 not apply to other service venues. These use of addictive substances and the reactions of ambiguous rules serve as a disincentive to health those around them, or their experiences of professionals to offer screening and brief adverse social and health consequences intervention services and an incentive to keep associated with such use. For example, while substance-related services divorced from risky alcohol use commonly is defined simply as 219 mainstream medicine. These tools also do not follow consistent standards nor are they designed to be tailored to ever had a drink first thing in the morning to the unique patterns, symptoms and steady your nerves or to get rid of a hangover 222 consequences of substance use of different age (Eye-opener)? Further, most screening instruments focus on specific other drug use (excluding nicotine) asks: (1) substances independently rather than identifying Have you ever ridden in a Car driven by risky use of all addictive substances or risk for addiction as a unified disease. Sensitivity refers to ‡ For example, any use of addictive substances by an instrument’s ability to identify correctly the children, adolescents or pregnant women constitutes presence of a condition; the higher the sensitivity the risky use; risky alcohol use is defined differently for less likely the instrument is to produce false women vs. Specificity is an instrument’s ability to individuals with co-occurring health conditions poses identify correctly those without the condition; the extreme risks even at levels that may be considered higher the specificity, the less likely the instrument is relatively safe among those without such conditions. An affirmative answer to each question is worth one point and a cut-off score of two is recommended for identifying 223 risky alcohol and other drug use, even though any use of addictive substances by adolescents is 224 considered risky. The typical screening process also may fail to distinguish those individuals with a higher level of substance involvement and the associated health and social consequences (including the risk for addiction) from those with lower levels of involvement--a distinction necessary for 225 providing appropriate interventions. In accordance with standard medical practice for the treatment of other chronic diseases, best practices for the effective treatment and management of addiction must be consistent with the scientific evidence of the causes and course of the disease. Behavioral therapies are those psychosocial interventions that focus more directly on addressing the patient’s substance-related behaviors, typically through behavioral reinforcement approaches, with less of an emphasis on the psychological or social determinants of their substance use. It is grounded in a public health model for addiction involving nicotine to be ignored in that addresses system and service coordination; the course of treating addiction involving health promotion and prevention, screening and alcohol or other drugs. Accordingly, when early intervention; treatment and recovery; and treating addiction, it is critical to recognize the resiliency supports to promote social integration 4 high rates of co-occurrence of different and optimal health and productivity. Treating the disease of occurring medical, including mental health, addiction involves addressing not only the problems exist and allow for the development of 10 specific object of the addiction, but the an appropriate and specific treatment plan. Assessment tools, as distinguished from screening tools, are meant to determine the The bottom line is that addiction is an illness that presence and severity of a clinical condition and we are able to treat and manage, if not cure, should parallel, at least in part, established ‡ provided that we focus on the person with the diagnostic criteria for the disease. Assessments addiction, the family and the community--a tools also might examine social, family and 8 holistic approach to a sprawling problem.

For example, in addition to perform a comprehensive assessment of the determining the patient’s health status, the stage patient’s medical, psychological and substance 14 and severity of the disease and the family use history and current health status, present history of addiction, the assessment should symptoms of addiction, potential withdrawal determine personality traits such as syndrome and related addictive behaviors.

It is * important that assessment instruments also offer Despite the distinction between screening and some degree of cultural sensitivity and that they assessment tools, the term screening often is used to 17 subsume the concept of assessment or are age and gender appropriate. Furthermore, while there is some overlap between screening or assessment procedures used to identify risky substance use and methods † used to diagnose a clinical addiction, a formal See Appendix H for some examples of assessment diagnosis of addiction should be based on the instruments used by practitioners and researchers to demonstration of specific symptoms included in the help make these diagnoses.
