[Pronunciation: subcutaneous = sub-kyoo-TAY-nee-us; cannula = CAN-yoo-luh; hypoglycemia = high-po-gly-SEE-mee-uh; occlusion = oh-KLOO-zhun] Welcome to your insulin pump training. In the next two minutes, we'll look at how the pump delivers insulin, and what you'll do each day to keep it working well. An insulin pump is a small, computerized device that delivers rapid-acting insulin through thin tubing to a soft cannula placed just under the skin, in the subcutaneous tissue. Together, the tubing and cannula are called the infusion set. The pump gives insulin in two ways. First, basal insulin: a small, steady trickle delivered throughout the day and night, to cover your body's background needs. Second, a bolus: an extra amount you request before meals, or to correct a high glucose reading. Your pump's settings are programd with your diabetes care team. Don't change them on your own. Each day, check your infusion site for redness, swelling, or leaking. Change the infusion set and rotate the site on the schedule your care team gives you. Using the same spot over and over can cause lumps under the skin that affect how insulin is absorbed. Pay attention to alarms. An occlusion alarm means insulin isn't flowing, often because the tubing is kinked or the cannula is blocked. Because a pump uses only rapid-acting insulin, an interruption can lead to high blood glucose quickly. Know the signs of low blood glucose, or hypoglycemia: shakiness, sweating, confusion, a racing heart. Keep fast-acting sugar with you, and follow the plan your team has given you. Finally, always carry backup supplies, and keep a backup plan for insulin injections in case the pump stops working. Your pump is a powerful tool. Your care team is your guide. Let's get started.

[Pronunciation: glomerulus = glow-MAIR-yoo-lus; glomerular = glow-MAIR-yoo-lur; afferent = AF-er-ent; efferent = EF-er-ent; arteriole = ar-TEER-ee-ole; Bowman's capsule = BOW-munz CAP-sool; Henle = HEN-lee; creatinine = kree-AT-ih-neen] Each of your kidneys contains around a million tiny filtering units called nephrons. Together, they filter the body's entire plasma volume dozens of times a day, keeping what the body needs and removing what it doesn't. Let's follow the path. Blood arrives through a small artery called the afferent arteriole. It flows into the glomerulus, a tight knot of capillaries that sits inside a cup-shaped structure called Bowman's capsule. Here, pressure pushes water and small molecules, such as sodium, glucose and urea, out of the capillaries and into the capsule. Blood cells and most proteins are too large, and stay behind. This is glomerular filtration. The blood then leaves through the efferent arteriole. The rate of filtration across both kidneys is called the glomerular filtration rate, or GFR. It's one of the most important measures of kidney function, and it's usually estimated from a blood test for creatinine. The filtered fluid, now called filtrate, moves into the renal tubule. In the proximal convoluted tubule, most of the water and sodium, and nearly all of the glucose, are reabsorbed into the blood. Next comes the loop of Henle, which dips down into the medulla. Its descending limb lets water out. Its ascending limb pumps salt out. Together, they build a concentration gradient that lets the kidney produce concentrated urine. In the distal convoluted tubule and the collecting duct, final adjustments are made, guided by hormones such as aldosterone and antidiuretic hormone. What remains flows on as urine. Filter. Reabsorb. Fine-tune. Every minute of every day, the nephron balances the body's water, salt and waste.

[Pronunciation: cholecystectomy = koh-lee-sis-TEK-toh-mee; laparoscopic = lap-uh-roh-SKOP-ik; pneumoperitoneum = noo-moh-pair-ih-toh-NEE-um; Trendelenburg = tren-DEL-en-burg; cephalad = SEF-uh-lad; infundibulum = in-fun-DIB-yoo-lum; hepatocystic = HEP-uh-toh-SIS-tik] This module reviews the key steps of laparoscopic cholecystectomy, with an emphasis on achieving the critical view of safety. The patient is positioned supine under general anesthesia. Pneumoperitoneum is established, and ports are placed: typically one at the umbilicus for the camera, with additional working ports in the epigastrium and right upper quadrant. The patient is placed in reverse Trendelenburg and rotated slightly to the left, allowing the bowel to fall away from the operative field. The fundus of the gallbladder is grasped and retracted cephalad over the liver. The infundibulum is retracted laterally, opening the hepatocystic triangle. Dissection begins. The peritoneum is incised on both the anterior and posterior aspects of the triangle, and fatty and fibrous tissue are cleared. Before any structure is clipped or divided, the critical view of safety must be established. Three criteria must be met. One. The hepatocystic triangle is cleared of fat and fibrous tissue. Two. The lower third of the gallbladder is separated from the liver bed, exposing the cystic plate. Three. Two structures, and only two, are seen entering the gallbladder: the cystic duct and the cystic artery. Only when all three criteria are confirmed are the cystic duct and artery clipped and divided. Many teams document the view with a photograph or video capture. If the critical view cannot be achieved, because of severe inflammation or unclear anatomy, consider a bailout strategy, such as subtotal cholecystectomy, or conversion to an open procedure. Choosing a bailout is a sign of good judgment, not failure. The gallbladder is then dissected from the liver bed, placed in a retrieval bag, and removed through a port site. The critical view of safety. In every case.

[Pronunciation: percutaneous = per-kyoo-TAY-nee-us; ostium = OSS-tee-um; stenosis = steh-NO-sis; atherosclerotic = ath-er-oh-skler-OT-ik; angioplasty = AN-jee-oh-plas-tee; restenosis = ree-steh-NO-sis; antiplatelet = an-tee-PLATE-let] Percutaneous coronary intervention, or PCI, is a procedure used to open narrowed or blocked coronary arteries. It's performed in the cardiac catheterization lab, usually with the patient awake and lightly sedated. Access is gained through an artery, most often the radial artery at the wrist, or the femoral artery in the groin. A sheath is placed, and a guiding catheter is advanced to the opening, or ostium, of the coronary artery. Contrast dye is injected, and X-ray images called angiograms show the vessel in real time. The team identifies the stenosis: the narrowed segment caused by atherosclerotic plaque. Next, a very thin guidewire is steered across the stenosis. Over that wire, a balloon catheter is advanced to the narrowed segment and inflated. The balloon compresses the plaque and widens the channel. This is balloon angioplasty. In most cases, a stent is then placed. The stent is a small mesh tube mounted on a balloon. As the balloon inflates, the stent expands against the vessel wall, and it stays in place as a scaffold when the balloon is withdrawn. Most stents used today are drug-eluting. They release medication slowly into the vessel wall to reduce the growth of scar tissue that can narrow the artery again. That re-narrowing is called restenosis. Final angiograms confirm that blood is flowing freely. The catheters are removed, and the access site is closed or compressed. After PCI, patients are usually prescribed antiplatelet medicines to lower the risk of a clot forming inside the stent. Taking them as prescribed is critical. Stopping them early, without guidance from the cardiology team, can be dangerous. PCI. A single puncture. A wire, a balloon, a stent. And blood flow restored to the heart muscle.

[Pronunciation: endotracheal = en-doh-TRAY-kee-ul; bronchospasm = BRONG-koh-spaz-um; pneumothorax = noo-moh-THOR-ax; extubation = ex-too-BAY-shun] This module covers alarm response on the Arden V7 critical care ventilator. Alarms are your early warning system. Responding quickly and systematically keeps your patient safe. Alarm fatigue is real, but every alarm deserves a response. The V7 sorts alarms by priority. High-priority alarms show in red, with a repeating tone. Medium-priority alarms show in yellow. Never silence an alarm without assessing the patient first. Start with the patient, not the screen. Is the patient safe right now? Look at chest rise, skin color, oxygen saturation and the patient's comfort. Let's look at two of the most common alarms. High peak pressure. The ventilator is meeting more resistance as it delivers a breath. Common causes include secretions in the airway, a kinked or bitten endotracheal tube, coughing, bronchospasm, or the patient breathing against the ventilator. More serious causes include a pneumothorax. Assess, suction if indicated, and check the tubing from the patient back to the machine. Low pressure, or low exhaled volume. This usually means a leak or a disconnection somewhere in the circuit. Check every connection, and listen for an audible leak. Check the cuff of the endotracheal tube. Consider unplanned extubation, and check the tube's position at the lips. If you can't quickly identify and fix the problem, and your patient is in distress, disconnect the patient from the ventilator and begin manual ventilation with a bag-valve device connected to oxygen. Call for the respiratory therapist and the medical team. Remember the order. The patient first. Then the circuit. Then the machine. In the next section, you'll practice responding to these alarms on the simulator.

[Pronunciation: arthroplasty = AR-throh-plas-tee; quadriceps = KWOD-rih-seps; anticoagulant = an-tee-koh-AG-yoo-lunt] You've had a total knee replacement, also called a total knee arthroplasty. The worn surfaces of your knee joint have been replaced with smooth metal and plastic parts. Now your recovery begins, and you are a big part of it. Your care team will give you instructions that fit your surgery and your health. Always follow them first. This video will help you understand why they matter. Movement is medicine. You'll probably be up and walking, with help and a walker, soon after surgery. Your physical therapist will teach you exercises to bend and straighten your knee and to strengthen your quadriceps, the large muscles at the front of your thigh. Do them as often as you're asked, even when they're uncomfortable. Regaining your range of motion early makes a real difference later. Manage your pain so you can move. Take your pain medicine exactly as prescribed. Ice and elevation can help with swelling. Let your team know if your pain isn't under control. Protect against blood clots. After joint surgery, there's a higher risk of clots in the legs. Your team may prescribe an anticoagulant, compression stockings or simple ankle exercises. Call your care team right away if you notice new pain, warmth or swelling in your calf. Call emergency services if you have sudden shortness of breath or chest pain. Watch your incision. Keep it clean and dry, and follow your instructions for bathing. Call your surgeon if you see increasing redness or drainage, or if you have a fever. Make your home safe. Clear walkways, remove loose rugs, and keep the things you use most within easy reach. Recovery takes time. Many people see steady progress over the first few months. Be patient with yourself, keep moving, and stay in touch with your care team. They're with you every step of the way.

[Pronunciation: incretin = in-KREE-tin; glucagon = GLOO-kuh-gon; agonist = AG-uh-nist; semaglutide = sem-uh-GLOO-tide; liraglutide = lir-uh-GLOO-tide; pancreatitis = pan-kree-uh-TYE-tis] Welcome to module three of your therapeutic area training: understanding the GLP-1 receptor agonist class. Before you can talk confidently with health care professionals about any product in this space, you need to understand the physiology behind it. Let's start there. When we eat, cells in the gut release hormones called incretins. One of the most important is glucagon-like peptide one, or GLP-1. GLP-1 does several things. It stimulates the pancreas to release insulin, but mainly when blood glucose is raised. That glucose-dependent action is a point clinicians will ask you about. It also reduces the release of glucagon, a hormone that raises blood glucose. It slows gastric emptying, so nutrients enter the bloodstream more gradually. And it acts on the brain to increase feelings of fullness. The challenge is that natural GLP-1 is broken down within minutes by an enzyme called DPP-4. GLP-1 receptor agonists, such as semaglutide and liraglutide, are designed to mimic the hormone while resisting that breakdown. They activate the same receptors, for much longer. Clinicians use this class in type 2 diabetes, and some agents are also approved for chronic weight management. Certain agents have shown cardiovascular benefits in outcome trials. You'll also need to know the safety profile. The most common side effects are gastrointestinal: nausea, vomiting and diarrhea, often most noticeable when treatment starts. The class carries warnings you'll study in detail, including pancreatitis and, for some agents, a warning about thyroid C-cell tumors. One reminder. In every conversation, you'll discuss only approved uses, and you'll present benefits and risks with fair balance, as covered in your compliance training. In module four, we'll look at the clinical evidence.

[Pronunciation: pharmacovigilance = FAR-muh-koh-VIJ-ih-lunss; adverse = AD-verse] Welcome to compliance essentials for field representatives. In this module, we'll cover two principles that shape every conversation you have with a health care professional: on-label promotion and fair balance. Let's start with on-label promotion. Every prescription medicine is approved for specific uses in specific patient populations. Those uses are described in the product's prescribing information, often called the label. As a representative, you may only promote a product for its approved uses. Promoting an unapproved use, known as off-label promotion, is prohibited, even if a clinician raises it first. So what do you do if a physician asks about an unapproved use? You don't answer it yourself. Explain that you can only discuss approved uses, and offer to submit a request to Medical Information, so a qualified medical colleague can respond directly. Now, fair balance. Whenever you present a product's benefits, you must also present its important risks, with comparable prominence. That means the risks aren't rushed, minimized, or left for the end of a meeting that runs short. If there's no time to cover the risks, there's no time to cover the benefits. Use only approved promotional materials. Don't create your own charts, summaries or comparisons. Finally, adverse events. If a health care professional mentions a side effect or problem experienced by a patient taking one of our products, you must report it to pharmacovigilance within the time frame set by company policy. You don't need to judge whether the product caused it. Just report it. On-label. Fair balance. Report adverse events. These aren't just rules. They protect patients, they protect clinicians' trust in you, and they protect your career. Now let's look at a scenario.

[Pronunciation: placebo = pluh-SEE-boh; investigational = in-vess-tih-GAY-shun-ul; randomized = RAN-duh-mized] Thank you for your interest in the ALDER-2 study. This video explains what taking part in a clinical trial means, so you can make an informed choice. It doesn't replace your conversation with the study team. Please ask them anything. A clinical trial is a research study that tests whether a treatment is safe and whether it works. This study is testing an investigational medicine. Investigational means it is not yet approved for this use. This is a randomized, double-blind, placebo-controlled study. Let's take those words one at a time. Randomized means a computer will assign you, by chance, to one of two groups. You won't choose your group, and neither will your doctor. This keeps the comparison fair. One group will receive the investigational medicine. The other will receive a placebo: something that looks the same, but contains no active medicine. Double-blind means that neither you nor the study team will know which group you are in until the study ends. This helps make sure the results aren't influenced by what anyone expects. If there's a medical need, the team can find out quickly. Taking part may involve extra visits, blood tests and questionnaires. The study team will explain the schedule, the possible risks and discomforts, and any possible benefits. You may not benefit directly, but the information gathered could help others in the future. Before you join, you'll be asked to read and sign an informed consent form. Take your time. Take it home if you like. Talk it over with family, or with your own doctor. Your participation is entirely voluntary. You can leave the study at any time, for any reason, and it won't affect the care you would normally receive. If you have questions now, or at any point during the study, contact your study team. Their details are on your information sheet. Thank you for considering it.

[Pronunciation: endodontic = en-doh-DON-tik; apical foramina = AY-pih-kul for-AM-ih-nuh; pulpitis = pul-PYE-tis; necrotic = neh-KROT-ik; periapical = pair-ee-AY-pih-kul; hypochlorite = high-poh-KLOR-ite; obturated = OB-tyoo-ray-tid; gutta-percha = GUT-uh PUR-chuh] This module provides an overview of conventional endodontic treatment, more commonly known as root canal treatment, for dental nurses and dental students. Inside every tooth, beneath the enamel and dentine, is the pulp: soft tissue containing nerves and blood vessels. The pulp extends from the pulp chamber in the crown, down through the root canals, to openings at the root tips called the apical foramina. When the pulp becomes irreversibly inflamed, a condition called irreversible pulpitis, or when it becomes necrotic and infected, root canal treatment can preserve the natural tooth. Treatment begins with diagnosis, including clinical tests and a periapical radiograph. Once local anaesthesia is achieved, the tooth is isolated with a rubber dam. This keeps the field clean and dry, and protects the patient's airway from small instruments and irrigants. An access cavity is prepared through the crown to reach the pulp chamber, and the canal openings, or orifices, are located. Next, the working length is determined, using an electronic apex locator and radiographs. Files are then used to clean and shape each canal to that length. Throughout shaping, the canals are irrigated, commonly with sodium hypochlorite, to dissolve organic tissue and disinfect the canal system. Careful technique is essential, to avoid forcing irrigant beyond the root tip. Once the canals are shaped and dried, they're obturated, or filled, usually with gutta-percha and a sealer. The access cavity is then sealed with a temporary or permanent restoration. Many teeth, especially back teeth, will later need a crown to protect them from fracture. Accurate length, thorough disinfection, and a good seal. Those three goals guide every case.
