On occasion, warranted, the selection of empirical antifungal therapy (eg, an continued use of specifc combinations of antimicrobials echinocandin, triazoles such as fuconazole, or a formulation might be indicated even after susceptibility testing is available 592 www. Decisions on defnitive antibiotic choices and for selected forms of endocarditis, where prolonged should be based on the type of pathogen, patient characteristics, courses of combinations of antibiotics are warranted.

Combination therapy used in this context connotes at least two different classes of antibiotics (usually 3. We suggest the use of low procalcitonin levels or similar a beta-lactam agent with a macrolide, fuoroquinolone, or biomarkers to assist the clinician in the discontinuation aminoglycoside for select patients). A controlled trial sug- of empiric antibiotics in patients who appeared septic, but gested, however, that when using a carbapenem as empiric have no subsequent evidence of infection (grade 2C).

One recent study failed to show any beneft of daily procal- ized clinical trials is not available to support combination citonin measurement in early antibiotic therapy or survival (84). In some clinical scenarios, combination therapies activity against the most likely pathogens based upon each are biologically plausible and are likely clinically useful even patient’s presenting illness and local patterns of infection. Combination therapy for suspected or known patients with severe sepsis (grade 2B) and for patients with Pseudomonas aeruginosa or other multidrug-resistant Gram- diffcult-to-treat, multidrug-resistant bacterial pathogens negative pathogens, pending susceptibility results, increases such as Acinetobacter and Pseudomonas spp. We suggest that the duration of therapy typically be 7 to 10 with an extended spectrum beta-lactam and either an ami- days if clinically indicated; longer courses may be appropri- noglycoside or a fuoroquinolone is suggested for P. Although patient factors may infuence the length tings where highly antibiotic-resistant pathogens are preva- of antibiotic therapy, in general, a duration of 7-10 days (in the lent, with such regimens incorporating carbapenems, colistin, absence of source control issues) is adequate. However, a recent controlled trial continue, narrow, or stop antimicrobial therapy must be made suggested that adding a fuoroquinolone to a carbapenem as on the basis of clinician judgment and clinical information. Cli- empiric therapy did not improve outcome in a population at nicians should be cognizant of blood cultures being negative in low risk for infection with resistant microorganisms (85). We suggest that combination therapy, when used empirically despite the fact that many of these cases are very likely caused in patients with severe sepsis, should not be administered by bacteria or fungi. De-escalation to the most appro- cultures will be negative in a signifcant percentage of cases of priate single-agent therapy should be performed as soon as severe sepsis or septic shock, despite many of these cases are the susceptibility profle is known (grade 2B). We suggest that antiviral therapy be initiated as early as pos- excluded as rapidly as possible, and intervention be under- sible in patients with severe sepsis or septic shock of viral taken for source control within the frst 12 hr after the diag- origin (grade 2C). Recommendations for antiviral treatment identifed as a potential source of infection, defnitive inter- include the use of: a) early antiviral treatment of suspected vention is best delayed until adequate demarcation of viable or confrmed infuenza among persons with severe infuenza and nonviable tissues has occurred (grade 2B). If intravascular access devices are a possible source with infuenza caused by 2009 H1N1 virus, infuenza A (H3N2) of severe sepsis or septic shock, they should be virus, or infuenza B virus, or when the infuenza virus type or removed promptly after other vascular access has been infuenza A virus subtype is unknown (97, 98). The principles of source control in the manage- updated information regarding the most active, strain-specifc, ment of sepsis include a rapid diagnosis of the specifc site of antiviral agents during infuenza epidemics (99, 100). Such infectious foci should dations can be given based on the current level of evidence. We recommend that antimicrobial agents not be used in to delayed surgical intervention for peripancreatic necro- patients with severe infammatory states determined to be sis showed better outcomes with a delayed approach (111).

Vasopressor therapy is required to sustain life in an extensive number of literature entries (135–147). Norepinephrine is more potent than dopamine Hg has been shown to preserve tissue perfusion (134).

This has been called relative and produces hyperlactatemia, no clinical evidence shows that vasopressin defciency because in the presence of hypotension, epinephrine results in worse outcomes, and it should be the vasopressin would be expected to be elevated. Epinephrine may increase aerobic lactate demonstrated that survival among patients receiving < 15 µg/ production via stimulation of skeletal muscles’ β2-adrenergic min norepinephrine at the time of randomization was better receptors and thus may prevent the use of lactate clearance to with the addition of vasopressin; however, the pretrial rationale guide resuscitation. With its almost pure α-adrenergic effects, for this stratifcation was based on exploring potential beneft in phenylephrine is the adrenergic agent least likely to produce the population requiring ≥ 15 µg/min norepinephrine. Higher tachycardia, but it may decrease stroke volume and is therefore doses of vasopressin have been associated with cardiac, digital, not recommended for use in the treatment of septic shock except and splanchnic ischemia and should be reserved for situations in circumstances where norepinephrine is: a) associated with where alternative vasopressors have failed (167). Vasopressin levels in septic shock support the routine use of vasopressin or its analog terlipressin have been reported to be lower than anticipated for a shock state (93, 95, 97, 99, 159, 161, 164, 166, 168–170). We suggest not using intravenous hydrocortisone as a treat- vasopressors are instituted. We recommend that low-dose dopamine not be used for citation and vasopressor therapy are able to restore hemo- renal protection (grade 1A). A large randomized trial and meta-analysis com- alone at a dose of 200 mg per day (grade 2C). Thus, the available data do not support administration of sive septic shock (hypotension despite fuid resuscitation and low doses of dopamine solely to maintain renal function. These catheters also allow continuous trial failed to show a mortality beneft with steroid therapy analysis so that decisions regarding therapy can be based on (178).

We recommend that a trial of dobutamine infusion up to study baseline (placebo) 28-day mortality rate was 61% and 20 μg/kg/min be administered or added to vasopressor (if 31%, respectively. We recommend against the use of a strategy to increase car- with prolonged low-dose steroid treatment in adult septic diac index to predetermined supranormal levels (grade 1B). Both reviews, however, confrmed a combined inotrope/vasopressor, such as norepinephrine or the improved shock reversal by using low-dose hydrocortisone epinephrine, is recommended if cardiac output is not measured. Several randomized trials on the use of low-dose the subset of adults with septic shock who should receive hydrocortisone in septic shock patients revealed a signifcant hydrocortisone (grade 2B). Furthermore, considerable inter- tion was observed between responders and nonresponders in a individual variability was seen in this blood glucose peak after recent multicenter trial (178).

Men needed it, too, though the pathological consequences of abstinence were less dire for them. One text, the De passionibus mulierum B, omitted all discussion of general physi- ology and anatomy. The second adaptation, Non omnes quidem, deliberately omitted reference to virginity when it compressed Muscio’s original discussion of sexuality. The salubriousness of virginity was also actively suppressed in two later renderings of the Gynecology, one a late-twelfth-century Hebrew translation and the other a late- thirteenth-century Latin abbreviation called De naturis mulierum. Erler,‘‘EnglishVowedWomenatthe End of the Middle Ages,’’ Mediaeval Studies  (): –. These remedies consist of medicated pessaries intended to cause the corrupted seed to issue forth. Charles Talbot was the first to rec- ognize these figures as referring to the disease of uterine suffocation; see C. Talbot, Medicine in Medieval England (NewYork: Science History Publications, London: Old- bourne, ), pp. My interpretation of these scenes differs from that proposed by Laurinda Dixon, Peril- ous Chastity: Women and Illness in Pre-Enlightenment Art and Medicine (Ithaca, N.

Table 1: Lifestyle Medicine Compared to Other Approaches to Patient Care Type of Practice Features -Emphasis on promoting behavior changes that allow the body to heal itself. Conventional - Emphasis on making a diagnosis and treatment with pharmaceuticals or surgery Medicine1 -Patient is passive recipient of care -Focuses on symptoms or signs of disease not the underlying lifestyle causes. Medicine2 Focus on treatments such as acupuncture, biofeedback and nutraceuticals along with some evidence-based lifestyle interventions. Naturopathy/ -Emphasis on homeopathic and naturopathic treatments such as herbs and colonics. Homeopathy5 -Treatments may be based on traditional practices rather than scientific evidence. The first basic level involves the recognition by all health care providers that lifestyle is a significant determinant of health and an important modifier of individual patient responses to pharmaceutical or surgical treatments. At this level all physicians should use lifestyle interventions as an adjunct to their standard treatment protocols. All physicians should be encouraged to adopt a patient-centered communication style that fosters motivation and health literacy in their patients. Current medical training does not routinely include a focus on the use of evidence-based lifestyle interventions such as nutrition, exercise and stress management techniques in the treatment of lifestyle-related diseases. Similar to any medical practice the team will work under the supervision and guidance of a Licensed Physician who is trained or has demonstrated expertise in Lifestyle Medicine. The range and level of staffing needed to operate a Lifestyle Medicine practice will depend on the services offered, financial considerations and the needs of the community and the patients served, however it is highly recommended that Lifestyle Medicine practices include the following professionals as appropriate. Licensed Dietitians/Nutritionists Nutrition is an essential therapeutic intervention in Lifestyle Medicine. The knowledge and skills of the nutrition professional will determine the success of nutrition treatments offered by the practice. Exercise Physiologists/Exercise Coaches/Personal Trainers Fitness assessments and exercise prescriptions are essential components of a Lifestyle Medicine treatment plan and exercise professionals are essential members of a Lifestyle Medicine treatment team. They may or may not also be nutrition professionals but they are role models for patients and may be asked by patients for nutrition advice. All patients of a Lifestyle Medicine practice should receive the same clear consistent message from all members of their treatment team. Psychologist/Licensed Therapists/Health Coaches Behavior modification is the key element of Lifestyle Medicine treatment. Professionals who can assist patients to understand and transform unhealthy behaviors into health promoting ones are essential members of the Lifestyle Medicine treatment team. These professionals should have a degree in psychology or a related field or certification as a health coach; a valid state license to practice if needed; and training in the principles of Lifestyle Medicine to ensure that all patients get the same clear consistent message from all members of their treatment team.
