Thanks, Tom. This morning, I will review the performance of our major business segments; Pharmaceuticals, Nutritionals, and Medical Products including Diabetes Care, Diagnostics and Abbott Vascular. And you will have to forgive me, I have got head cold, so I may pause here occasionally. Let me start with our global Pharmaceutical business where sales increased more than 14% in the quarter, driven by 25% growth in international Pharmaceuticals. Excluding the impact of generic Omnicef, U.S. Pharmaceuticals increased approximately 14%. Including the impact, reported U.S. Pharmaceutical sales increased 3.6%. In Immunology, worldwide HUMIRA sales were up 54% to $878 million, which includes nearly 70% international growth. In 2008, we expect global HUMIRA sales will exceed $4 billion as HUMIRA continues to capture a majority of all patients new to anti-TNF therapy in a market that continues to grow double digit with HUMIRA driving a majority of that market growth. In the quarter, we continued to build our positions in both Dermatology and Gastroenterology segments, while maintaining our consistent share gains in Rheumatology. And with the FDA approval of two new indications in the first quarter alone, HUMIRA is now approved for six indications in total. In addition, this morning we are pleased to announce the approval of HUMIRA for rheumatoid arthritis in Japan. This new market opportunity represents to Abbott alone more than $300 million in additional peak year sales. We will co-market this product with Eisai in Japan. At the end of January, we launched HUMIRA for psoriasis and the result so far have exceeded our expectations. Our U.S. new prescription share in dermatology has grown by nearly 8 percentage points in just the first few months of launch, increasing our [inaudible] share in Dermatology to more than 20%. HUMIRA's early success in psoriasis is based on its outstanding clinical data. HUMIRA has raised the bar for what physicians and patients should expect for reliable skin clearance. We've demonstrated that nearly 75% of HUMIRA patients achieved a 75% reduction in their symptoms. In February, we presented new longer-term data at the American Academy of Dermatology meeting, demonstrating HUMIRA's durability of response. Unlike some other therapies, which decrease in response over time, HUMIRA clinical results continue to improve longer term, now out to 18 months. We also continue to see steady growth HUMIRA in Crohn's disease, which we launched just over a year ago. We've recently surpassed 35% share in Crohn's as we continue to see strong demand for HUMIRA as the biologic of choice for both new patients and those switching from other therapies. HUMIRA offers the only self-administered biologic treatment for Crohn's patients, providing a distinct convenience advantage over the competition. We'll also present new, longer-term Crohn's data at the Digestive Disease Week meeting this May, demonstrating HUMIRA's sustainability and durability of response. Crohn's and psoriasis are the two largest markets after rheumatoid arthritis, each at approximately $1 billion in sales today with strong double-digit growth expected over the next several years. Also in the quarter, we launched our sixth indication for HUMIRA, juvenile rheumatoid arthritis. HUMIRA is the first biologic treatment to receive FDA approval for this condition in almost a decade and the first to be self-administered once every two weeks. The growing awareness of HUMIRA among physicians and the growing body of best-in-class clinical data should continue to drive demand for HUMIRA. In our lipid management franchise in the first quarter, we received U.S. approval for Simcor in line with our expectations. The launch is very early, but is proceeding quite well. Our full primary care sales force is now promoting this new brand and was able to reach approximately 80,000 physicians during the first week of launch. Simcor combines two well-established medications, Niaspan and Simvastatin, to powerfully target multiple lipid parameters in a single therapy. Data from two Phase III trials have demonstrated Simcor's role in improving key lipid levels versus the use of a statin alone. We began shipping Simcor in early March with active sales force detailing, beginning in late March. Sales of Simcor in the quarter were close to $20 million, on track for our full-year sales forecast this year of approximately $100 million. Niaspan, our HDL-raising therapy, grew 24% in the first quarter. Since the launch last year of our new film-coated Niaspan tablets as well as the additional Abbott promotional efforts following the Kos acquisition, we have steadily increased Niaspan prescription share growth. Total prescriptions are now growing faster than the overall cholesterol market, our first for this product in more than two years. Niaspan is the only prescription therapy capable of increasing HDL 25% to 35% on average with proven cardiovascular outcomes. It's a safe, effective and very well known therapy. Flushing is a temporary side effect associated with any Niaspan therapy. For most patients this side effect is greatly reduced when Niaspan is taken with Aspirin, one of the safest and most trusted medications. In pivotal studies, less than 6% of Niaspan patients discontinued therapy due to a flushing side effect. Similar results were also seen in our two pivotal trials for Simcor, which contains Niaspan. This compares very favorably to the competitive data we've seen. We expect strong double-digit growth for Niaspan to continue throughout 2008. Also in the quarter Tricor sales were up nearly 10%. Tricor remains the best available therapy for lowering triglycerides with a long-established safety and efficacy profile. We also presented our pivotal Phase III clinical trial results on our new fenofibric acid molecule, TriLipix, at the American College of Cardiology meeting last month. Our goal with the development of TriLipix was to design an optimal compound that could be combined with statins to address the difficult-to-treat mixed dislipidemic patient population. These are patients with high triglycerides, low HDL and high LDL, more than 40 million patients in total. Our Phase III data showed that we met our clinical development goal. Results from two of our trials demonstrated the TriLipix in combination with Lipitor and Zocor significantly improve three key lipid parameters, doubling triglyceride reduction, doubling HDL improvement and producing clinically meaningful LDL reductions. This is the largest and first-ever clinical program to evaluate the efficacy and safety of a fibrate in combination with statins. We expect to present additional Phase III data from our TriLipix program throughout this year, including data from our third combination trial with CRESTOR at the National lipid Association meeting at the end of May and at a podium presentation at the American Diabetes Association meeting this June. We submitted TriLipix for FDA approval at the end of last year and we remain on track for FDA approval in the fourth quarter of this year. The next step in our development program is our partnership with AstraZeneca to combine TriLipix and CRESTOR as a fixed-dose therapy. This combination product is in Phase III development, and we expect to submit for regulatory approval in the second half of next year. With many unique therapies that address lipid problems beyond LDL alone, Abbott's lipid franchise is extraordinarily well positioned to address the growing needs for comprehensive lipid management now and over the long-term. For the full year, we expect continued strong double-digit growth in our lipid franchise. Moving on to HIV where both Kaletra and Norvir were up double digits worldwide in the first quarter, we recently announced European regulatory approval of a new lower strength formulation of Kaletra, which is suitable for pediatric use. Depakote sales in the first quarter were up double-digits. Depakote ER, our once-a-day version of Depakote, accounts for more than 50% of total Depakote prescriptions. And in the TAP joint venture, sales of both the PPI Prevacid and the hormone therapy Lupron, which Abbott will be receiving when the deal is closed, were in line with our expectations. Prevacid sales were $550 million, and in March TAP received a favorable court ruling against Teva upholding the validity and enforceability of Prevacid's compound patent. The compound patent extends through November of 2009, assuming a six-month pediatric extension. TAP's next generation PPI, TAK-390 MR, was also submitted for U.S. FDA approval in early January or late... actually late last year, and results from the Phase III clinical trial program will be at the upcoming Digestive Disease Week medical meeting in May. Lupron sales were $147 million in the first quarter, on track to achieve full-year sales of approximately $600 million. And as Tom mentioned, we expect to close on the TAP transaction in the second quarter. At that time, Abbott will begin selling Lupron as part of our domestic pharmaceutical business and we expect it to contribute approximately $400 million in sales this year, although as we mentioned annualized sales are closer to $600 million. As a reminder, the majority of Lupron sales come from its indication for prostate cancer where it holds market-leading share. It's also a leading therapy for endometriosis and central precocious puberty. The addition of Lupron will accelerate Abbott's on-market presence in oncology where we currently have several therapies in early and mid-stage development in our Abbott pipeline. So in summary, in Pharmaceuticals for the second quarter and the full-year, we expect double-digit sales growth for both our domestic and international Pharmaceutical businesses. In our global Nutritionals business, sales in the quarter were up nearly 11%, driven by 21% growth in international Nutritionals as demand continues to increase for high-quality nutritional products in emerging markets. We continue to see broad-based growth across our International Nutritionals business, including several very strong growth objectives in pediatric... in the pediatric segment. U.S. Nutritionals sales were up low single-digit, lead by growth of new products including our infant formula, Similac Sensitive. In the second quarter, we expect mid-single digit growth in our U.S. Nutritionals business and continued strong double-digit growth internationally. So if we turn now to our Medical Products businesses, let me start with Diabetes Care where worldwide sales increased more than 14%. In the U.S., we recently launched our second automated calibration meter, FreeStyle Freedom Lite. Both FreeStyle Lite and FreeStyle Freedom Lite meters eliminate the manual calibration step required by most glucose meters, which improves convenience for people with diabetes. In the U.S., we've also launched the FreeStyle Navigator continuous glucose monitoring system, which monitors glucose levels every minute. Continuous information about glucose levels allows patients to more closely manage their disease. Navigator was launched in Europe last year. We also further expanded our diabetes commercial presence in emerging markets where sales in Asia and Latin America grew at strong double-digit rates. And in the U.S., we recently initiated a new promotional program in major media outlets including television, radio and print. In the second quarter, we expect double-digit growth worldwide in our Abbott Diabetes Care business. Now, let me turn to our worldwide Diagnostics business where sales grew more than 17% in the quarter, driven by continued strong growth in our international business. We saw double-digit growth in our Immunochemistry and Hematology segment this quarter, driven by sales in Europe, Latin America and Asia, particularly China, where we had strong double-digit growth. Abbott PRISM sales and ARCHITECT placements drove U.S. performance in the quarter. In January, we received FDA approval for our fifth automated blood-screening test for PRISM, HTLV. We plan to further expand the PRISM menu with the launch of HIV. We also recently launched a new ARCHITECT platform, the i1000, to meet the needs of our smaller volume lab customers. We continue to gain share with our larger volume analyzers, which were launched at the end of last year. In our Point-of-Care business, sales in the quarter were more than 20%. Growth was driven by strong cardiac cartridge sales and further penetration of our CHEM 8 test, which received a claim for broader use last year. And in Molecular Diagnostics, sales also increased more than 20% in the quarter. Our m2000 real-time PCR System continues to gain share worldwide. In the U.S., we submitted chlamydia, gonorrhea test for FDA [ph] approval for the m2000 system and additional infectious disease submissions are planned for later this year. We continue to expand our presence in the area of Pharmacogenomics. As part of this strategy, we entered into a collaboration agreement with Genentech recently to develop a companion diagnostic test for their cancer medication, Tarceva. We also made an equity investment in Ibis, a subsidiary of Isis, for the development of a new Molecular Diagnostics technology. So in the second quarter, our worldwide Diagnostics businesses, we anticipate continued double-digit growth. This includes continued strong double-digit growth in both Molecular Diagnostics as well as Point-of-Care and high single-digit growth in Immunochemistry and Hematology. In our Vascular business, in the quarter global sales were driven by approximately 35% growth internationally, as we continue to drive share and launch XIENCE into new geographies. As expected, U.S. sales were impacted by year-over-year declines in PCI volume and third-party catheter sales, although we do see very encouraging signs in the market as both U.S. PCI volume and DES penetration improved sequentially from the fourth quarter of last year, with DES penetration ending the month of March at the highest level we've seen in nearly a year in the mid-to-high 60s. So let me start with XIENCE where we ended February with XIENCE-only share, excluding France, in the low to mid 20s. In February, we were granted reimbursement for XIENCE in France, the second largest DES market in Europe. XIENCE launch has got off to a strong start with share already in the high-teens in France several weeks post-launch, given the outstanding commercial execution we've seen from our sales and marketing efforts in France. Our first quarter results only include two weeks of sales, given that our international business reports on a one-month lag. Recently, we also launched a 2.25-millimeter version of XIENCE in international markets, offering physicians access to a wider range of stent sizes to treat a variety of patient types. We expect to see a more meaningful impact from the 2.25 product and France launches in the second quarter. In the U.S., we continue to expect a second-quarter launch for XIENCE. The strong body of scientific data for XIENCE as well as our highly experienced U.S. Vascular sales force positions us extremely well for launch. In fact, we have one of the largest U.S. Vascular sales forces in the industry, which is nearly 100% intact post the Guidant acquisition. Recall that Abbott maintains market share leadership in bare-metal stents with approximately 60% VisionShare. So our commercial team knows how to win in what remains a highly competitive market. In addition, we remain confident in our manufacturing capacity. As we’ve said many times in the past, we can supply more than 50% of the worldwide market at this time. Outside of the U.S., our ex-U.S. team has begun to promote XIENCE with longer-term data. This includes one-year data on more than 1000 patients from our SPIRIT III trial. In addition, a few weeks ago at the American College of Cardiology meeting, we presented follow-up data for XIENCE. Two-year clinical results from our smaller ex-U.S. SPIRIT II clinical trial demonstrated a 40% reduction in major adverse cardiac events or MACE compared to TAXUS. MACE is an important clinical measure of safety and efficacy outcomes for patients and physicians and is defined as cardiac death, heart attack or ischemia-driven target lesion revascularization. XIENCE has consistently reduced MACE by 40% or more compared to TAXUS at any given time point measured in SPIRIT II or SPIRIT III clinical trials. In mid-May, at EuroPCR, we look forward to presenting two-year data from our larger 1,000-patient U.S. pivotal trial, SPIRIT III. We are pleased today to confirm that this data has been accepted as a late-breaker presentation and the lead investigator of the trial, Dr. Gregg Stone, will be highlighting the data at a podium presentation. We'll also present four-year data from SPIRIT I as well as 30-day data from SPIRIT V, which is our 2,700 patient registry trial that completed enrollment at the end of the last year. Additionally, we anticipate publication of the one-year SPIRIT III data very soon. We continue to enroll patients in our U.S. continued access trial, SPIRIT IV, which now has more than 3,000 patients enrolled. As a reminder, we expanded SPIRIT IV to nearly 3,700 patients in this trial last year, which is evaluating the primary end-point of MACE at one year. So for the quarter, our global DES franchise sales, which include XIENCE as well as our third-party DES product revenues, were approximately $100 million for the quarter, up nearly 30% sequentially from the fourth quarter. Despite an expected high single-digit decline in U.S. PCI volumes versus the first quarter of last year, worldwide coronary stent sales, which include bare-metal and drug-eluting stents, were up more than 18% in the quarter. PCI volumes also impacted other coronary sales where we saw lower third-party catheter sales in the first quarter. As a sign of market recovery however, U.S. PCI volumes were up sequentially versus the fourth quarter, and DES penetration also improved to the mid-to-high 60% range at the end of March. This is encouraging as we continue to see evidence that the DES market has stabilized and we anticipate the entry of new next-generation DES technology, including XIENCE, will help to improve market growth as we move throughout the year. Looking forward to the second quarter in Vascular, we expect double-digit growth for the business. Finally, let me take a few minutes to address our overall pipeline. [inaudible] after submitting a record number of major new products for approval last year, we've already received several regulatory approvals and begun to launch process for a number of products. And we continue to execute on every phase of our late-stage pipeline and regulatory approval. As I've mentioned, already this year we have launched HUMIRA for psoriasis and juvenile rheumatoid arthritis, as well as Simcor for comprehensive cholesterol treatment. In diabetes, we received U.S. approval for FreeStyle Navigator, our continuous glucose meter... monitor, as well as the launch of FreeStyle Freedom Lite. Also this year, we anticipate FDA approval for our drug-eluting stent, XIENCE V, as Tom said in the second quarter; our next-generation fenofibrate, TriLipix, and our controlled-release branded medication, Vicodin CR. And in the next several months, we plan to present data on several of our pipeline compounds. Upcoming data that I haven't mentioned includes the first presentation of our Phase III pivotal trial data in chronic pain for controlled-release Vicodin at the American Pain Society meeting in May. This past February, we presented data from our Vicodin CR long-term safety trial as well as additional efficacy trials. We submitted Vicodin CR to FDA at the end of last year from moderate to moderately severe pain indication and anticipate approval at the end of this year. From our early stage pipeline, we'll be presenting data at the American Psychiatric Association in May on ABT-089, one of neuroscience compounds for ADHD, as well as early stage data from our oncology compounds at ASCO in June. We believe we have one of the highest productivity rates for late-stage pipeline products in our industry. As a result, 2008 is one of the most significant years for Abbott in terms of major new product launches, including three major new products that have been accepted by the agency and are currently under active FDA review, including XIENCE, TriLipix and Vicodin CR. So in summary, we are pleased with our results for the quarter. In 2008, we continue to expect another year of double-digit performance accelerating as well. With that, we'll now open up the call for questions. Question and Answer
