Criticisms and Limitations: patients were excluded from the study if their treating physician felt that renal artery revascularization was clearly indicated cholesterol lowering foods plant sterols buy 5mg rosuvastatin mastercard. T us cholesterol count chart buy 5 mg rosuvastatin free shipping, there may have been a selection bias such that patients less likely to beneft from revascularization were disproportionately included in the study. Additionally, 41% of enrolled patients had a renal artery stenosis <70%, which may not be severe enough to cause complications such as hypertension or renal dysfunction. However, a post hoc analysis of this study and subsequent studies involving patients with more severe stenosis have also failed to demonstrate a beneft with revascularization (see the following section). Guidelines from the National Kidney Foundation recommend that the decision about whether to treat patients with renovascular disease with revascularization versus medical ther- apy should be made on a case-by-case basis. Further research will be needed to determine which subgroups of patients, if any, beneft from revascularization. T e patient’s physician initiates him on amlodipine and when he returns one month later he is found to have a blood pressure of 162/98 and a serum cre- atinine of 2. Suggested Answer: T is patient has renal artery stenosis complicated by hypertension and kid- ney disease. T us, it would be appropriate to treat him medically with statins, antiplate- let agents, and antihypertensives. Further research will be needed to deter- mine whether subgroups of patients with severe disease might beneft from revascularization.

Year Study Began: 2002 Year Study Published: 2006 Study Location: 130 sites in the United States. Who Was Excluded: patients on renal replacement therapy at the time of enrollment. Also excluded were patients with “uncontrolled hypertension, active gastrointestinal bleeding, an iron overloaded state, a history of frequent transfusions in the last 6 months, refractory iron defciency anemia, active can- cer, previous therapy with epoetin alfa, or patients with unstable angina. Patients with Chronic Kidney Disease and Anemia Randomized Target Hemoglobin of 13. Study Intervention: patients in both groups received weekly subcutaneous injections of epoetin alfa initially at a dose of 10,000 units. Afer the third weekly injection, the epoetin alfa dose was adjusted to target a hemoglobin level of either 13. The maximum dose of epoetin alfa could not exceed 20,000 units in either group, and dosing could be switched to every other week for patients with stable hemoglobin levels. Importantly, patients in both groups who began renal replacement therapy were no longer eligible to participate in the study and began receiving usual care once this occurred. Endpoints: primary outcome: A composite of death, myocardial infarction, hospitalization for congestive heart failure (ChF), and stroke. Secondary out- comes: Time to renal replacement therapy; hospitalization for any cause; and changes in quality-of-life scores. Criticisms and Limitations: Of the study population, 38% did not complete follow-up (21% for unlisted reasons and 17% due to the initiation of dialysis). Because the study was unblinded, it is possible that physicians’ knowledge of patients’ study assignment impacted their decision to initiate dialysis, which could have biased the results. Reassuringly, however, the proportion of patients 118 Neph RoLogy who initiated dialysis was similar between the groups, and an analysis in which dialysis initiation was combined with the primary composite outcome showed results congruent with the primary analysis. Other Relevant Studies and Information: • The Normal Hematocrit Trial evaluated 1,233 patients with cardiovascular disease who were on hemodialysis and found that targeting a hematocrit of 42% compared to 30% yielded no cardiovascular or mortality advantage and was associated with increased risk of thrombosis of grafs and fstulas. The decision to start treatment should be based on the rate of fall in hemoglobin and a discussion of risks and benefts with the patient.

A modified Seldinger technique is used to obtain access over a soft wire using fluoroscopic guidance cholesterol joint pain rosuvastatin 10 mg with visa. Another arterial access involves placing a 6F to 8F short sheath in the common femoral artery using the modified Seldinger technique (long sheaths cholesterol levels tester buy 5mg rosuvastatin mastercard, such as 23 or 35 cm vap cholesterol test quest discount 10mg rosuvastatin fast delivery, can be used if there is significant tortuosity and/or additional support is required). Using fluoroscopic guidance when entering the femoral artery above the inferior margin of the femoral head but below the pelvic rim increases the likelihood of entering the common femoral artery at a compressible site above the common femoral artery bifurcation and below the inferior epigastric artery. The superficial/profunda femoral artery bifurcation is best seen in the ipsilateral 30° to 40° projection. The brachial and radial arteries can accommodate up to 7F and 6F sheaths, respectively. Ulnar artery and digital arch patency should be confirmed via the Allen and/or Barbeau test in case the radial artery becomes occluded (approximately 3% to 5%). Radial access improves hemostasis and earlier ambulation but may have slightly increased radiation exposure. The choice of coronary equipment is no longer limited because of technologic advances in 6F to 7F compatible devices. Larger guide size (7F or 8F) provides extra support and permits the use of larger rotational atherectomy burrs and use of simultaneous kissing stents. The Amplatz guide catheter is also the most likely catheter to traumatize the ostial/proximal coronary artery in inexperienced hands because of its tendency to deeply engage the vessel. The choice of a wire depends on the wire tip’s stiffness, and support characteristics. Stiff tips are helpful to penetrate chronic total occlusions but increase the risk of vessel dissection or perforation. Hydrophilic wires are quite slippery and may be used to cross tortuous high-grade lesions, but can easily cause dissection or end-vessel perforation. Support wires also typically have stiffer tips and are primarily used as a supportive rail to deliver coronary equipment through tortuous vessels. Both short (approximately 180 cm) and long (approximately 300 cm) wires are available. Most operators prefer the routine use of a rapid exchange (Rx) system, which uses a monorail that permits easy exchange over a short wire, although situations that require an over-the-wire system may be better served with the use of a longer wire to avoid dislodging the wire during equipment exchanges. This complementary imaging modality can be invaluable when repeated angiographic views fail to determine the mechanism and/or significance of a coronary lesion. The superior image quality allows an evaluation of stent apposition, poststent dissection, and analysis of plaque characteristics and plaque rupture. This information is helpful in determining whether a moderate-grade coronary stenosis (i. Using wave- intensity analysis, a period of diastole in which equilibration occurs between pressure waves from the aorta and distal microcirculation was identified at approximately 75% into diastole (ending 5 ms before the R-wave). A balloon-tipped Swan–Ganz catheter advanced to the pulmonary arteries allows measurement of right and left heart filling pressures as well as the cardiac output. The coronary balloon remains the backbone of endovascular intervention, although it is almost never used as a stand-alone therapy. The initial gain in the coronary lumen achieved by balloon inflation results in localized dissection of the intima (and often the media) plus distension of the adventitia. The dissection is covered by platelet-rich thrombus and later by new intimal layers. As a result of these inevitable dissections, the abrupt closure rate is 4% to 7%, although the use of more potent contemporary antithrombotic therapies has reduced this rate. Present-day coronary stents are flexible, laser-cut and polished, balloon- mounted, and expandable, slotted tubes composed of either stainless steel or metal composites such as cobalt–chromium. First implanted in 1986 and used for emergency treatment of coronary dissection after angioplasty, the early era of the intracoronary stent placement was plagued by high rates of subacute closure despite intensive anticoagulation regimens that often led to bleeding complications and prolonged hospitalization. Evolution of stent design, high-pressure implantation of stents, and advances in periprocedural antithrombotic regimens led to a rapid reduction in procedural complication rates and marked improvement in the ease of stent delivery. Antiproliferative agents such as sirolimus, paclitaxel, zotarolimus, and everolimus arrest cell division during the mitotic growth phase. The Resolute stent makes use of the Driver platform with a newly designed polymer that allows a delayed release of the drug for out to 3 months. The Resolute Integrity stent elutes zotarolimus from Medtronic’s Integrity stent platform. Stent thrombosis is defined as early (<30 days), late (30 days to 1 year), and very late (>1 year).

Relationship Patterns Relationship patterns are often unpredictable cholesterol friendly foods list order cheapest rosuvastatin, chaotic, impulsive, and highly sexual- ized. Some people with manic features inspire followers and protégés, whose moods are elevated by sharing in the manic persons’ grand schemes. In this context, we note that the psychodynamic treatment of bipolar states is likely to be daunting. Therapists may have trouble keeping up with the (hypo-)manic phases and may be bewildered by rapid shifts between these phases and depressed ones. Coffee and “herbal remedies” increased her energies and elevated her mood, but she also needed alcohol to quell excessive agitation. She became hyperactive and impulsively accepted several dates, on which she felt high sexual arousal. Thinking she had a “special ability” at prophecy, she approached friends and colleagues to pre- dict their futures. Her work functioning decreased significantly, as her hyperactivity was not focused properly. S25 Maternal Affective Disorders During pregnancy, a mother normally enters a mental state of “primary maternal pre- occupation,” which involves heightened sensitivity toward, and intense identification with, her developing baby. With the baby’s birth, she develops a new mental organiza- tion that has been called the “motherhood constellation. The mother reorganizes her self-identity, putting her baby first and herself second. The puerperium is a well-recognized time of increased vulnerability to depression. Sociocultural evolution has led to a relative disappearance of the functional extended Symptom Patterns: The Subjective Experience—S Axis 161 family that traditionally aided mothers; this support has not been replaced by any other social unit or health structure, although recent research has found that home visits to teenage mothers enhance parenting, reduces maternal risks, and improves child developmental outcomes. Understanding this phase is crucial because difficul- ties during pregnancy and in the postpartum period have a profound impact on the mother–baby dyad and on the baby’s developing mental organization. Three relevant conditions within the category of maternal affective disorders, in order of severity, are maternity blues, postpartum depression, and puerperal psy- chosis. Professional consultation is recommended for maternity blues and considered mandatory for postpartum depression and puerperal psychosis. Maternity Blues The term “maternity blues” (or “baby blues”) denotes a common, relatively mild, tran- sient mood disturbance. Dysphoria or mood swings peak between the third and fifth day after childbirth, with some cultural variation (e. A family history of depression and a personal history of depression or premenstrual dysphoria are common. Risk factors include stressful events, poor social adjustment, ambivalence in families, economic difficulties, and unplanned pregnancies. Symptoms may include transient tearful episodes, anxiety, headache, fatigue, emotional lability, irritability, depersonalization/derealization, and depressed mood. Maternity blues may have serious consequences, however, including compromise of emotional closeness and maternal competence (see also Chapter 10). Mothers can be fragile in the postpartum period and generally benefit from family ties, especially if these are not compromised by prior conflicts. Postpartum Depression Postpartum depression is a significant health problem affecting 10–20% of new moth- ers yearly. It involves persistent sadness; frequent crying; emotional lability; poor con- centration; memory troubles; feelings of worthlessness, inadequacy, or guilt; irrita- bility; loss of interest in self-care; not feeling up to everyday tasks; loss of energy; anxiety; bizarre thoughts and fears; obsessive thoughts of harm to the baby; feeling overwhelmed; and loss of pleasure in previously enjoyable activities, including sex. Thoughts of death or suicide are common, continuing beyond 2 weeks after delivery. Women vulnerable to depression prior to delivery tend to have depressions that extend into the postpartum period. It leads to inse- cure attachment patterns and increased risk of untreated emotional problems in chil- dren.
