Long-term mortality and incidence of renal dialysis and transplantation in type 1 diabetes mellitus.

AIMS: We investigated long-term mortality and requirement of renal replacement therapy (RRT) in type 1 diabetes mellitus (T1DM) to study risk factors and late complication incidence of T1DM in a prospective cohort study at Lainz Hospital, Vienna, Austria. METHODS: In 1983-1984, T1DM patients [n = 648; 47% females, 53% males; age, 30 +/- 11 yr; T1DM duration, 15 +/- 9 yr; body mass index, 24 +/- 4 kg/m(2); glycated hemoglobin (HbA1c), 7.6 +/- 1.6%] were stratified into HbA1c quartiles [1st, 5.9 +/- 0.5% (range, 4.2-6.5%); 2nd, 6.9 +/- 0.3% (6.6-7.4%); 3rd, 7.9 +/- 0.3% (7.5-8.4%); and 4th, 9.6 +/- 1.3% (8.5-14.8%)]. Twenty years later, both endpoints (death and RRT) were investigated by record linkage with national registries. RESULTS: At baseline, creatinine clearance, blood pressure, and body mass index were comparable among the HbA1c quartiles, whereas albuminuria was more frequent in the 4th quartile (+15%; P < 0.03). After the 20-yr follow-up, 13.0% of the patients had died [rate, 708 per 100,000 person-years (95% confidence interval, 557-859)], and 5.6% had received RRT [311 per 100,000 person-years (95% confidence interval, 210-412)]. Patients with the highest HbA1c values (4th quartile) had a higher mortality rate and a greater incidence of RRT (P < 0.04). In the Cox proportional hazards analysis, age, male gender, increased HbA1c, albuminuria, and reduced creatinine clearance were predictors of mortality (P < 0.05). Predictors of RRT were albuminuria (P < 0.001), reduced creatinine clearance (P < 0.001), and belonging to the 4th HbA1c quartile (P = 0.06). In Kaplan-Meier analysis, mortality was linearly associated with poor glycemia, whereas RRT incidence appeared to rise at a HbA1c threshold of approximately 8.5%. CONCLUSION/INTERPRETATION: In the Lainz T1DM cohort, 13.0% mortality and 5.6% RRT were directly associated with and more frequently found in poor glycemia, showing that good glycemic control is essential for the longevity and quality of life in T1DM.

A simple score predicts future cardiovascular events in an inception cohort of dialysis patients.

Vascular calcifications are very common in dialysis patients and have been shown to be associated independently with outcome. However, all of these studies used prevalent patients on dialysis since many years. We investigated vascular calcifications in an inception cohort of dialysis patients and followed them for cardiovascular disease outcomes during an average observation period of 66 months. One hundred and fifty-four Caucasian dialysis patients were enrolled in one Austrian dialysis center. Standardized plain radiographs from the pelvis and calves were carried out in all patients at the start of dialysis therapy. Vascular calcifications were assessed by a single radiologist. At the start of renal replacement therapy, 67.5% of the patients showed vascular calcifications. During follow-up, 29.9% of patients suffered a cardiovascular event. An additive 'vascular risk score', constructed from the presence of vascular calcifications and/or previous cardiovascular events before the start of dialysis treatment, showed the strongest independent association with cardiovascular events in the Cox regression model adjusted for various risk factors. The presence of each of these two conditions was associated with a hazard ratio of 2.03 (95% confidence interval 1.19-3.46) and a hazard ratio twice as high if both conditions were present. In summary, vascular calcifications on plain X-rays of pelvis and calves are largely present in incident dialysis patients. A history of a cardiovascular event in the predialysis period together with vascular calcifications at the beginning of dialysis therapy is a more powerful predictor of a cardiovascular event than age, smoking, diabetes, or other traditional risk factors.

Analysis of formononetin from black cohosh (Actaea racemosa).

Black cohosh has been widely used as an herbal medicine for the treatment of symptoms related to menopause in America and Europe during the past several decades, but the bioactive constituents are still unknown. Formononetin is an isoflavone with known estrogen-like activity. This compound was first reported to be isolated from black cohosh in 1985, but subsequent research in 2002 using HPLC-PDA and LC-MS revealed no evidence to show the presence of formononetin in 13 populations of American black cohosh. A more recent report published in 2004 claimed to detect formononetin in an extract of black cohosh rhizomes using a TLC-fluorescent densitometry method. To further resolve these conflicting reports, we analyzed black cohosh roots and rhizomes for the presence of formononetin, using a combined TLC, HPLC-PDA and LC-MS method. We examined both methanolic and aqueous methanolic black cohosh extracts by HPLC-PDA and LC-MS methods, and did not detect formononetin in any extracts. We further determined the limits of detection of formononetin by HPLC-PDA and LC-MS. Our experimental results indicated that the sensitivity and accuracy of the HPLC-PDA and LC-MS methods for the analysis of formononetin were slightly higher than those of the reported fluorescent method, suggesting that the HPLC-PDA and LC-MS methods were reliable for the analysis of formononetin from black cohosh. We also repeated the reported TLC method to concentrate two fractions from a modern black cohosh sample and an 86-year-old black cohosh sample, respectively, and then analyzed these two fractions for formononetin using the HPLC-PDA and LC-MS method instead of the fluorescent method. Formononetin was not detected by HPLC-PDA or LC-MS. From the results of the present study it is not reasonable to attribute the estrogen-like activity of black cohosh extracts to formononetin.

Ankle-brachial index and peripheral arterial disease.

Patients with peripheral arterial disease including those with intermittent claudication have a high risk for cardiovascular and cerebrovascular morbidity and mortality. The outcome of patients with intermittent claudication is less limited by local complications in the leg than by the systemic complications of coronary and cerebral vessels. About 30 % of these patients will die within 5 years, three-quarters of them due to vascular events. Analyses using data of the KORA Study 2004/2005 (F3), a follow-up examination of the participants of the MONICA Survey 1994/95 (S3), will try to identify biochemical as well as genetic risk factors for peripheral arterial disease. The anti-atherogenic apolipoprotein A-IV will be one of our candidates of interest.

[How about the uncertainty in the haplotypes in the population-based KORA studies?].

In the KORA surveys, numerous candidate genes in the context of type 2 diabetes, myocardial infarction, atherosclerosis or obesity are under investigation. Current focus is on genotyping single nucleotide polymorphism (SNPs). Haplotypes are also of increasing interest: haplotypes are combinations of alleles within a certain section of one chromosome. Analysing haplotypes in genetic association studies is often more efficient than studying the SNPs separately. A statistical problem in this context is the reconstruction of the phase: genotyping the SNPs determines the alleles of an individual at one particular locus of the DNA, but does not reveal which allele is located on which one of the two chromosomes. This information is required when talking about haplotypes. There are statistical approaches to identify the most likely two haplotypes of an individual given the genotypes. However, a certain error in prognosis is unavoidable. There are also errors in the genotypes. These errors are assumed to be small for one SNP but can accumulate over the SNPs involved in one haplotype and thus can induce further uncertainty in the haplotype. It is therefore the aim of our project to quantify the uncertainties in the haplotypes particularly for genes investigated in the KORA surveys. We conduct computer simulations based on the haplotypes and their frequencies observed in the KORA individuals and compare the results with simulations based on mathematical modelling of the evolutionary process ("coalescent models"). The uncertainties in the haplotypes have an impact on the search for association between genes and disease: an association may not be detected as the haplotype uncertainty obscures the haplotype frequency differences between cases and controls. It is a further aim of our project to elucidate the extent of this problem and to develop strategies for reducing it.

Association of the 103I MC4R allele with decreased body mass in 7937 participants of two population based surveys.

BACKGROUND: The melanocortin-4-receptor gene (MC4R) is part of the melanocortinergic pathway that controls energy homeostasis. In a recent meta-analysis, the MC4R V103I (rs2229616) polymorphism was shown to be associated with body weight regulation. Although no functional differences between the isoleucine comprising receptor and the wild type receptor have been detected as yet, this meta-analysis of 14 case-control studies reported a mild negative association with obesity (odds ratio (OR) 0.69, p = 0.03). However, evidence in a large population based study in a homogeneous population and a significant estimate of the change in quantitative measures of obesity is still lacking. METHODS: We analysed the data of two surveys of a white population with the same high quality study protocol, giving a total of 7937 participants. RESULTS: By linear regression, we found a significant decrease of 0.52 body mass index (BMI) units (95% confidence interval (CI) -0.02 to -1.03, p = 0.043) for carriers of the heterozygote rs2229616G/A genotype, which was observed in 3.7% of the participants. Logistic regression yielded a significantly negative association of the MC4R variant with "above average weight" (BMI > or = median BMI) yielding an OR of 0.75 (95% CI 0.59 to 0.95 p = 0.017). We obtained similar results comparing obese (BMI > or =30 kg/m2, World Health Organization results for 1997) with non-obese (BMI < 30 kg/m2) participants. The results were found for both sexes and each survey separately, and did not depend on the modelling of age, sex, or survey effects. CONCLUSIONS: Our study confirms previous findings of a meta-analysis that the relatively infrequent G/A genotype of the V103I MC4R polymorphism is negatively associated with above average weight and obesity in population based original data of 7937 participants, and extends previous findings by showing for the first time a significantly lower BMI in individuals carrying the infrequent allele of this MC4R variant.

The value of plant collections in ethnopharmacology: a case study of an 85-year-old black cohosh (Actaea racemosa L.) sample.

Ethnopharmacological collections of plants used in traditional medical systems are a valuable but often underappreciated resource for scientific investigation. These collections contain many samples of plants currently employed in herbal and pharmaceutical medicine, and questions on stability and storage life can be examined using these historic collections as vouchers. A sample of black cohosh (Actaea racemosa L.), collected in 1919 by the physician and plant explorer Henry Hurd Rusby, was recently identified in the collections of The New York Botanical Garden and analyzed for its triterpene glycosidic and phenolic constituents qualitatively and quantitatively by high-performance liquid chromatography-photodiode array detector (HPLC-PDA) and liquid chromatography-mass spectrophotometry (LC-MS). A comparison of the triterpene glycosidic and phenolic constituents of the 85-year-old plant sample with those of a modern collection of Actaea racemosa showed the similarity of the two samples, confirming the stability of the older sample, despite its curation over the years under a variety of conditions. Quantitative analyses indicated that both plant samples have similar amounts of the four major triterpene glycosides, but the total amount of the six major phenolic constituents measured in the 85-year-old plant material is lower than the amount measured in the modern plant material. Methanol extracts of the two plant materials were tested for their antioxidant activity, and both extracts showed similar antioxidant activity.

Neuropathic pain after femoropopliteal bypass surgery.

OBJECTIVE: This retrospective study was performed to investigate prolonged postoperative pain in the area of the proximal or distal scar or the bypass tunnel after femoropopliteal bypass surgery to treat symptomatic peripheral arterial disease. PATIENTS AND METHODS: Ninety-three patients with peripheral arterial disease who underwent femoropopliteal bypass surgery between January 2000 and December 2002 were included in the study. The short-form McGill Pain Questionnaire was used to score pain. Ultrasound examination of the soft tissue around the graft was performed to exclude other pathologic conditions responsible for pain, such as inflammatory processes, perigraft reactions, swollen lymph nodes, and hematomas. RESULTS: Pain in at least one scar existed in 22 patients on average 13.9 +/- 9.8 months after surgery. In 10 patients pain existed simultaneously along the inguinal scar and the above-knee or below-knee scar. Pain along the bypass tunnel was experienced by seven patients. Most patients had mild to moderate pain. The mean numeric ranking score of pain severity in patients with pain was 4.2 +/- 2.3. The occurrence of prolonged postoperative pain was not associated with age, gender, diabetes, indication for surgery, material or type of bypass, number of preceding operations, or postoperative wound complications. Only follow-up time after femoropopliteal bypass surgery tended to be lower in patients with pain compared with those without pain. CONCLUSION: Prolonged postoperative neuropathic pain along the distal and proximal incision or the bypass tunnel exists in one fourth of patients after femoropopliteal bypass surgery. Patients should be informed of this kind of complication before surgery. The results of our study justify further investigations of the origin and treatment of this pain, to find effective methods to reduce the incidence of prolonged postoperative pain after femoropopliteal bypass surgery.

Decrease of plasma apolipoprotein A-IV during weight reduction in obese adolescents on a low fat diet.

OBJECTIVE: Apolipoprotein (apo) A-IV is an antiatherogenic apolipoprotein, which may be involved in the regulation of food intake. Plasma apoA-IV is elevated in human obesity and apoA-IV polymorphisms have been associated with the extent of obesity. Our aim was to determine the effects of weight loss on plasma apo-IV in obese adolescents and to examine the relation of apoA-IV with the degree of obesity. DESIGN: Longitudinal intervention study of a low fat hypocaloric diet conducted in a dietary camp. SUBJECTS: Two groups of obese adolescents (n=47 and n=29), age: 12.7+/-1.7 and 11.7+/-2.6 y, relative body mass index (RBMI): 168+/-24 and 175+/-34%, respectively. MEASUREMENTS: Plasma total apoA-IV, apoA-I, apoB, plasma distribution of apoA-IV, leptin, lipids, and lipoproteins before and after 3 weeks of weight reduction. RESULTS: Plasma apoA-IV decreased from 11.5+/-4.1 mg/dl before to 6.7+/-2.2 mg/dl after weight reduction in the first group (P<0.001) and to a similar extent in the second group. The relative amount of lipid-free apoA-IV and apoA-IV associated with apoA-I increased slightly, whereas apoA-IV associated with lipoproteins devoid of apoA-I decreased. ApoA-IV levels before and after weight reduction and the changes in plasma apoA-IV did not independently correlate with RBMI, weight loss, or plasma leptin. CONCLUSION: Plasma apoA-IV decreases markedly in overweight adolescents undergoing short-term weight reduction. The decrease is not directly related to the degree of weight loss and the mechanisms underlying this reduction remain to be clarified.

Black cohosh, a menopausal remedy, does not have estrogenic activity and does not promote breast cancer cell growth.

Black cohosh is an increasingly popular alternative to estrogen replacement therapy for the relief of menopausal symptoms, primarily hot flushes. However, an important consideration for long-term therapy is potential toxicity and carcinogenicity. Therefore, we undertook a study to assess the estrogenic activity of black cohosh to examine its safety for those with, or at high risk of developing, breast cancer. Several assays were utilized as listed: RNAse protection assays, which ascertain the regulation of the expression of E2-responsive genes; estrogen-responsive-element (ERE)-luciferase, which determines modulation of the ER function by transactivation of the ERE; the Ishikawa cell system, which has an E2-regulated endogenous alkaline phosphatase; and colony formation of ER-expressing breast cancer cells, which indicates possible progression of early stage breast cancer into a more aggressive state. Black cohosh extracts did not demonstrate estrogenic activity in any of these assay systems. This is an encouraging step in the assessment of the safety of black cohosh for treatment of menopausal hot flushes.

Analysis of thirteen populations of black cohosh for formononetin.

Black cohosh (Actaea racemosa L. syn. Cimicifuga racemosa (L.) Nutt.), a North American perennial plant, is a promising natural alternative to hormone replacement therapy for treating menopausal symptoms, but the mechanism of action is not understood. The clinical actions of this plant have been attributed to the isoflavonone formononetin since 1985, when its presence was reported in a black cohosh extract. Others have since looked for formononetin, but have not detected it. We looked for formononetin in extracts of black cohosh roots and rhizomes collected in thirteen locations in the eastern United States, including Maryland, New Jersey, New York, North Carolina, Pennsylvania, Virginia, and Tennessee. The rhizome samples were extracted using 80% methanol, and the extracts were partially purified using solid-phase extraction to concentrate any isoflavonoids that might be present. We tested for formononetin in these partially purified samples using thin-layer chromatography and high-performance liquid chromatography with a photodiode array detector and a mass spectrometer. Formononetin was not detected in any of the thirteen plant populations examined. Remifemin, a German product now on the United States market, and CimiPure, a commercially available black cohosh rhizome extract, were also analyzed. We did not detect formononetin, or ononin (formononetin-7-glucoside), in any sample tested by the above-mentioned chemical analyses. Therefore, the clinically observed estrogen-like actions of black cohosh, such as reduction of hot flashes, are likely due to a compound, or combination of compounds, other than formononetin.

Association of plasma bilirubin with coronary heart disease and segregation of bilirubin as a major gene trait: the NHLBI family heart study.

Decreased serum bilirubin levels have been associated with coronary heart disease (CHD). It is believed that bilirubin acts as an antioxidant, preventing formation of oxidized LDL and subsequent atherosclerosis. Serum bilirubin also segregates as a major gene, with the rarer genotype associated with elevated bilirubin levels and occurring in about 12% of the population. Using a large population-based study of random and CHD high risk families, this analysis was designed to replicate the association of lower serum bilirubin levels with early CHD (onset by age 55 for males and 65 for females) using 328 case/control samples and the major gene segregation of bilirubin levels in 555 families. There were significant differences in plasma bilirubin levels between 188 males (12.5 micromol/l) and 140 females (9.3 micromol/l, P<0.0001). Higher serum albumin and lower HDL-C significantly correlated with higher plasma bilirubin levels in females but not males. In sex-specific logistic regression models of early CHD (148 cases and 180 controls), lower plasma bilirubin was associated with increased prevalence of CHD in males with borderline significance (odds ratio=0.93 for a 1 micromol/l increase in bilirubin, P=0.056) but not in females. Bilirubin was found to segregate as a major gene using all 555 families consisting of 1292 individuals, with estimates replicating those in the previously published study. The most parsimonious model was a recessive model for high bilirubin levels that occurred in about 23% of the population. The means were separated by 1.7 standard deviations and there was a significant polygenic effect (h2=0.33, P=0.0009). We conclude that decreased bilirubin is mildly related to CHD in males but not in females. Because of an inverse correlation between HDL-C and bilirubin, the protective high HDL-C levels may have counteracted the CHD risk associated with lower bilirubin levels in females. The inferred major gene for bilirubin may protect against CHD, since elevated levels, rather than lower levels, were associated with this inferred gene.

Chronic renal transplantation: a model for the hyperhomocysteinemia of renal insufficiency.

Renal transplant recipients (RTR) are considered representative of patients with chronic renal insufficiency (CRI) in general with respect to both reduced, progressively declining renal function, and increased risk for cardiovascular disease (CVD). In accord with this argument, we hypothesized that total (t) plasma concentrations of the putatively atherothrombotic amino acid homocysteine (Hcy) would be equivalent in RTR and CRI patients with comparable renal function. We determined plasma tHcy, folate, pyridoxal 5'-phosphate, and B12 concentrations, in addition to serum creatinine and albumin concentrations, in 86 chronic, stable RTR, and 238 patients with CRI. Within comparable ranges of serum creatinine (i.e. RTR=0.6-4.2 mg/dl; CRI=0.7-4.1 mg/dl), tHcy concentrations did not differ between the two groups (RTR=15.0 micromol/l; CRI=14.9 micromol/l, P=0.899). ANCOVA revealed that renal function, gauged as a simple creatinine measurement, was the major independent determinant of plasma tHcy concentrations, accounting for approximately 80-90% of the total variability in tHcy predicted by the full model (i.e. full model R(2)) containing, in addition to creatinine, the seven other potential explanatory variables. If controlled trials confirm that tHcy-lowering treatment reduces CVD events rates in RTR, these results should be applicable to CRI patients in general.

Proteinuria and plasma total homocysteine levels in chronic renal disease patients with a normal range serum creatinine: critical impact of true glomerular filtration rate.

Conflicting data have been reported concerning the independent association between proteinuria and plasma total homocysteine (tHcy) levels, particularly among chronic renal disease (CRD) patients with a normal range serum creatinine. Studies of this potential relationship have been limited by failure to assess true GFR, failure to assess proteinuria in a quantitative manner, or arbitrary restriction of the range of proteinuria examined. We examined the potential independent relationship between plasma tHcy levels and a wide range of quantitatively determined proteinuria (i.e., 0.000-8.340 g/day), among 109 CRD patients with a normal range serum creatinine (range; 0.8-1.5 mg/dl; median=1.2 mg/dl). Glomerular filtration rate (GFR) was directly assessed by iohexol clearance, and plasma status of folate, pyridoxal 5'-phosphate, and B12, along with serum albumin, were also determined. Linear modeling with ANCOVA revealed that proteinuria was not independently associated with tHcy levels (partial R=0.127; P=0.201), after adjustment for potential confounding by GFR (partial R=0.408; P<0.001), age, sex, plasma B-vitamin status, and serum albumin. Moreover, descending across quartiles (Q) [from Q4 to Q1] of GFR, ANCOVA-adjusted (i.e., for age, sex, and folate status) geometric mean tHcy levels (micromol/l) were significantly increased: tHcy Q4 GFR=9.6; tHcy Q3 GFR=10.5; tHcy Q2 GFR=11.9; tHcy Q4 GFR=14.5; P<0.001 for overall Q difference. We conclude that across a broad spectrum of quantitatively determined proteinuria, after adjustment for true GFR, in particular, there is no independent relationship between proteinuria and tHcy levels among CRD patients with a normal range serum creatinine.

Global Forum on Safety of Herbal and Traditional Medicine: July 7, 2001, Gold Coast, Australia.

This report provides a summary of the background and inputs of various groups who attended the Global Forum on Safety of Herbal and Traditional Medicine conference held in the Gold Coast, Australia, on July 7, 2001. Keynote presentations covered the status of regulation of complementary medicine in Australia and comparative examples from Africa and Bangladesh. There was substantial input about work to date on databases, reflecting the need to have a focus on safety outcomes as a point of direction for the forum. Safety evaluation, which incorporates quality procedures, was identified as another point of focus. Clear evidence for the nonutilization of plants known to contain certain compounds producing deleterious effects was exemplified via data and information on the dangers of ingesting pyrrolizidine alkaloids.

Use of complementary and alternative medicine among women in New York City: a pilot study.

OBJECTIVE: This study documents the use of complementary and alternative medicine (CAM), among White, African American, and Hispanic/Latina women living in New York City. A pilot to a national survey of CAM use among American women, this study explores women's use of categories of CAM and various CAM practitioners, racial and ethnic differences in CAM use, and women's perceptions regarding the effectiveness of CAM. DESIGN AND LOCATION: Data were collected from women residing in New York City using random digit dialing/computer-assisted telephone interviewing (CATI). The sample of 300 had equal numbers of women (n = 100) who self-identified as White, Hispanic/Latina, and African American, equally stratified by age (below and above age 40). SUBJECTS: Eligibility requirements included self-identification as Anglo/white, African American, or Hispanic/Latina and between ages 18 and 80. MEASURES: Three distinct categories of CAM were explored: (1) medicinal teas, homeopathic remedies, herbs, vitamins; (2) yoga, meditation, spiritual practices; and (3) manual therapies including chiropractic, massage, acupressure. Health concerns of interest were those frequently described in prior focus groups, and included reproductive health issues (e.g., pregnancy, menstruation, menopause) as well as other common women's health problems (e.g., heart disease, high blood pressure, headaches). RESULTS: More than half the sample has used a CAM treatment or remedy, and 40% have visited a CAM practitioner. Among users, half have used only one of the CAM categories, approximately one third have used two, and 16% used all three. The category of CAM used most often was medicinal tea/herbs/vitamins; the practitioners visited most frequently were chiropractors (18%) and nutritionists (17%). Racial and ethnic differences in CAM use were minimal, and approximately one third of all treatments used were rated "very effective" by users. CONCLUSIONS: Substantial utilization of CAM remedies and treatments for a variety of women's health concerns is observed. Further inquiry with larger samples of women is recommended.

A comprehensive information resource on traditional, complementary, and alternative medicine: toward an international collaboration.

OBJECTIVES: A prototype for a comprehensive information resource for traditional complementary and alternative medicine (TCAM) has been developed to fill the considerable needs of a broad audience for worldwide access to TCAM information. The proposed resource is to be a comprehensive, vocabulary-controlled, integrated, standardized, multimedia information resource for TCAM. It will facilitate international cooperation, promote synergistic development of individual resources, promote dissemination of TCAM knowledge, and map the interrelationships among the TCAM traditions. METHODS: We organized two workshops for representatives of international databases that contain significant information on various aspects of alternative medicine. For the first workshop, we prepared and demonstrated a prototype named Complementary and Alternative Medicine Digital Library (CAMed) to illustrate the anticipated structure, content, and functionality of the comprehensive resource. We then constructed a second prototype to demonstrate the possibilities of searching across the collaborating databases and presented it to the representatives at the second workshop. OUTCOMES: Representatives of nine international databases attended the two workshops, in Bangalore, India (1998), and in Seoul, Korea (1999). We presented the prototypes at the workshops. Prototype I uses a Web interface, and supports browsing and searching from a variety of access points. Prototype II demonstrates a functional system that provides simultaneous access to selected represented databases by searching thesauri of these databases through our system. The group formalized itself as the International Collaboration for Information on Complementary and Traditional Medicine (IC2TM) with a goal of fully realizing the potential of the project.
