This review provides the reader with the up-to-date evidence-based basis for prescribing exercise as medicine in the treatment of 26 different diseases: psychiatric diseases (depression, anxiety, stress, schizophrenia); neurological diseases (dementia, Parkinson's disease, multiple sclerosis); metabolic diseases (obesity, hyperlipidemia, metabolic syndrome, polycystic ovarian syndrome, type 2 diabetes, type 1 diabetes); cardiovascular diseases (hypertension, coronary heart disease, heart failure, cerebral apoplexy, and claudication intermittent); pulmonary diseases (chronic obstructive pulmonary disease, asthma, cystic fibrosis); musculo-skeletal disorders (osteoarthritis, osteoporosis, back pain, rheumatoid arthritis); and cancer. The effect of exercise therapy on disease pathogenesis and symptoms are given and the possible mechanisms of action are discussed. We have interpreted the scientific literature and for each disease, we provide the reader with our best advice regarding the optimal type and dose for prescription of exercise.

Exercise as medicine – evidence for prescribing exercise as therapy in 26 different chronic diseases

This is the fourth updated Enhanced Recovery After Surgery (ERAS®) Society guideline presenting a consensus for optimal perioperative care in colorectal surgery and providing graded recommendations for each ERAS item within the ERAS® protocol. A wide database search on English literature publications was performed. Studies on each item within the protocol were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts and examined, reviewed and graded according to Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. All recommendations on ERAS® protocol items are based on best available evidence; good-quality trials; meta-analyses of good-quality trials; or large cohort studies. The level of evidence for the use of each item is presented accordingly. The evidence base and recommendation for items within the multimodal perioperative care pathway are presented by the ERAS® Society in this comprehensive consensus review.

Guidelines for perioperative care in elective colonic surgery: Enhanced recovery after surgery (ERAS®) society recommendations

Importance The human and financial costs of treating surgical site infections (SSIs) are increasing. The number of surgical procedures performed in the United States continues to rise, and surgical patients are initially seen with increasingly complex comorbidities. It is estimated that approximately half of SSIs are deemed preventable using evidence-based strategies. Objective To provide new and updated evidence-based recommendations for the prevention of SSI. Evidence Review A targeted systematic review of the literature was conducted in MEDLINE, EMBASE, CINAHL, and the Cochrane Library from 1998 through April 2014. A modified Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence and the strength of the resulting recommendation and to provide explicit links between them. Of 5759 titles and abstracts screened, 896 underwent full-text review by 2 independent reviewers. After exclusions, 170 studies were extracted into evidence tables, appraised, and synthesized. Findings Before surgery, patients should shower or bathe (full body) with soap (antimicrobial or nonantimicrobial) or an antiseptic agent on at least the night before the operative day. Antimicrobial prophylaxis should be administered only when indicated based on published clinical practice guidelines and timed such that a bactericidal concentration of the agents is established in the serum and tissues when the incision is made. In cesarean section procedures, antimicrobial prophylaxis should be administered before skin incision. Skin preparation in the operating room should be performed using an alcohol-based agent unless contraindicated. For clean and clean-contaminated procedures, additional prophylactic antimicrobial agent doses should not be administered after the surgical incision is closed in the operating room, even in the presence of a drain. Topical antimicrobial agents should not be applied to the surgical incision. During surgery, glycemic control should be implemented using blood glucose target levels less than 200 mg/dL, and normothermia should be maintained in all patients. Increased fraction of inspired oxygen should be administered during surgery and after extubation in the immediate postoperative period for patients with normal pulmonary function undergoing general anesthesia with endotracheal intubation. Transfusion of blood products should not be withheld from surgical patients as a means to prevent SSI. Conclusions and Relevance This guideline is intended to provide new and updated evidence-based recommendations for the prevention of SSI and should be incorporated into comprehensive surgical quality improvement programs to improve patient safety.

Considerable knowledge has accumulated in recent decades concerning the significance of physical activity in the treatment of a number of diseases, including diseases that do not primarily manifest as disorders of the locomotive apparatus. In this review we present the evidence for prescribing exercise therapy in the treatment of metabolic syndrome-related disorders (insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity), heart and pulmonary diseases (chronic obstructive pulmonary disease, coronary heart disease, chronic heart failure, intermittent claudication), muscle, bone and joint diseases (osteoarthritis, rheumatoid arthritis, osteoporosis, fibromyalgia, chronic fatigue syndrome) and cancer, depression, asthma and type 1 diabetes. For each disease, we review the effect of exercise therapy on disease pathogenesis, on symptoms specific to the diagnosis, on physical fitness or strength and on quality of life. The possible mechanisms of action are briefly examined and the principles for prescribing exercise therapy are discussed, focusing on the type and amount of exercise and possible contraindications.

Evidence for prescribing exercise as therapy in chronic disease.

BACKGROUND Since the patient’s skin is a major source of pathogens that cause surgical-site infection, optimization of preoperative skin antisepsis may decrease postoperative infections. We hypothesized that preoperative skin cleansing with chlorhexidine–alcohol is more protective against infection than is povidone–iodine. METHODS We randomly assigned adults undergoing clean-contaminated surgery in six hospitals to preoperative skin preparation with either chlorhexidine–alcohol scrub or povidone–iodine scrub and paint. The primary outcome was any surgical-site infection within 30 days after surgery. Secondary outcomes included individual types of surgical-site infections. RESULTS A total of 849 subjects (409 in the chlorhexidine–alcohol group and 440 in the povidone–iodine group) qualified for the intention-to-treat analysis. The overall rate of surgical-site infection was significantly lower in the chlorhexidine–alcohol group than in the povidone–iodine group (9.5% vs. 16.1%; P = 0.004; relative risk, 0.59; 95% confidence interval, 0.41 to 0.85). Chlorhexidine–alcohol was significantly more protective than povidone–iodine against both superficial incisional infections (4.2% vs. 8.6%, P = 0.008) and deep incisional infections (1% vs. 3%, P = 0.05) but not against organ-space infections (4.4% vs. 4.5%). Similar results were observed in the per-protocol analysis of the 813 patients who remained in the study during the 30-day follow-up period. Adverse events were similar in the two study groups. CONCLUSIONS Preoperative cleansing of the patient’s skin with chlorhexidine–alcohol is superior to cleansing with povidone–iodine for preventing surgical-site infection after cleancontaminated surgery.

Chlorhexidine–Alcohol versus Povidone–Iodine for Surgical-Site Antisepsis

Background Little information exists concerning the amount of information patients expect from physicians as to the risk for an adverse medication reaction. The present study was designed to determine such opinions in a population sample; to correlate results with sex, age, educational level, and previous experience with adverse effects; and to determine whether patients believe physicians should use discretion in the amount of such information given. Methods Two thousand five hundred sequential adults visiting outpatient clinics filled out a 12-item questionnaire. Percentages of subjects desiring information about varying degrees of risk and those believing physicians should and should not use discretion in the amount of such information provided were recorded. Results were correlated with demographic variables and previous experience of adverse effects. Results Among the respondents, 76.2% desired to be told of all possible adverse effects; 13.3% only if an adverse effect occurred 1 in 100 000 times; and 10.2% only if such occurrence was 1 in 100 times; 0.4% were not interested in any information. (Percentages have been rounded and do not total 100.) Percentages were closely similar to those for the same question that restricted opinion to serious adverse effects. Desire for maximum information was significantly correlated with lower educational level (P Conclusion Most individuals desire from physicians all information concerning possible adverse effects of prescribed medication and do not favor physician discretion in these decisions.

OBJECTIVE: To develop a meta-analysis to determine the effectiveness of rehabilitation in patients with chronic obstructive pulmonary disease (COPD). DATA SOURCES: MEDLINE, CINHAL, and Cochrane Library searches for trials of rehabilitation for COPD patients. Abstracts presented at national meetings and the reference lists of pertinent articles were reviewed. STUDY SELECTION: Studies were included if: trials were randomized; patients were symptomatic with forced expiratory volume in one second (FEV1) <70% or FEV1 divided by forced vital capacity (FEV1/FVC) <70% predicted; rehabilitation group received at least 4 weeks of rehabilitation; control group received no rehabilitation; and outcome measures included exercise capacity or shortness of breath. We identified 69 trials, of which 20 trials were included in the final analysis. DATA EXTRACTION: Effect of rehabilitation was calculated as the standardized effect size (ES) using random effects estimation techniques. RESULTS: The rehabilitation groups of 20 trials (979 patients) did significantly better than control groups on walking test (ES=0.71; 95% confidence interval [95% CI], 0.43 to 0.99). The rehabilitation groups of 12 trials (723 patients) that used the Chronic Respiratory Disease Questionnaire had less shortness of breath than did the control groups (ES=0.62; 95% CI, 0.35 to 0.89). Trials that used respiratory muscle training only showed no significant difference between rehabilitation and control groups, whereas trials that used at least lower-extremity training showed that rehabilitation groups did significantly better than control groups on walking test and shortness of breath. Trials that included severe COPD patients showed that rehabilitation groups did significantly better than control groups only when the rehabilitation programs were 6 months or longer. Trials that included mild/moderate COPD patients showed that rehabilitation groups did significantly better than control groups with both short- and long-term rehabilitation programs. CONCLUSION: COPD patients who receive rehabilitation have a better exercise capacity and they experience less shortness of breath than patients who do not receive rehabilitation. COPD patients may benefit from rehabilitation programs that include at least lower-extremity training. Patients with mild/moderate COPD benefit from short- and long-term rehabilitation, whereas patients with severe COPD may benefit from rehabilitation programs of at least 6 months.

Rehabilitation for Patients With Chronic Obstructive Pulmonary Disease: Meta-analysis of Randomized Controlled Trials

Aims
People who use illicit drugs are thought to have high rates of cigarette smoking; however, few population-based studies have been reported. We describe smoking patterns among illicit drug users, assess whether cigarette smoking is more prevalent among illicit drug users than it is among non-users and explore how smoking relates to level and type of drug use.

Design, setting, participants
We used adult responses to the 1997 National Household Survey on Drug Abuse (n = 16 661). Multivariate analyses used SUDAAN to adjust standard errors for the sampling design and controlled for age, race, sex, education, depression, treatment history and alcohol.

Measurements
Smoking rates, cessation rates and smoking levels.

Findings
Seventy-one per cent of recent illicit drug users smoked cigarettes at least once in the past month. Their adjusted odds of being a smoker were much greater than for the general population (OR = 3.07, P < 0.0001). Their quit rate, although substantial, was half that of non-users (23% versus 56%, P = 0.0001). Odds of being a smoker were higher for poly- versus monodrug users (OR = 2.35, P = 0.0020) and rose with increased drug use (OR = 1.36, P = 0.0374). Illicit drug users who perceived smoking to be risky were four times less likely to smoke (OR = 0.23, P = 0.0008).

Conclusions
Although most recent illicit drug users smoke, some are able to quit. Better understanding of concurrent cigarette and illicit drug use may provide impetus for policy change and shed light on underlying mechanisms of addiction. Clinicians, policy makers and user advocates should address tobacco use in drug treatment and in harm reduction interventions.

OBJECTIVES: To examine whether geographic proximity to mammography facilities influences mammogram utilization.



DESIGN: Retrospective cohort analysis.



SETTING: Rural state.



PARTICIPANTS: Female Kansas Medicare beneficiaries aged 65 to 79 (N = 117,901).



MEASUREMENTS: Using Medicare claims data, we measured county-level mammography rates for beneficiaries in Kansas. We calculated mammography rate differences for beneficiaries according to age, race, distance from permanent and mobile mammography sites, and county characteristics including county mammography service availability.



RESULTS: Of 105 counties, 37% had only permanent mammography facilities, 22% had both permanent and mobile sites, 29% had only mobile facilities, and 11% had neither, representing 44%, 44%, 9%, and 3% of the 117,901 beneficiaries, respectively. Of the beneficiaries, 91% lived less than 20 miles from a permanent facility; of the remaining 9%, 67% lived less than 20 miles from a mobile site. In 30 counties with only mobile sites, 90% of the 10,439 beneficiaries residing in the counties had access to the sites fewer than 2 days per month. County-level mammography rates ranged from 37% to 72%. Mammography utilization was 57% in counties with permanent facilities only, 55% in counties with both permanent and mobile sites, 53% in counties with only mobile sites, and 53% in counties with neither (P = 0.12). After adjusting for age, race, and county education level, the odds of receiving a mammogram was slightly lower for persons residing longer distances from a permanent facility (odds ratio = 0.97 for each 5-mile increase in distance, 95% confidence interval = 0.95–0.99).



CONCLUSION: The majority of Kansans live near a mammography facility. Although there is a large variation in county-level mammography rates across Kansas, this disparity is not well explained by proximity to mammography facilities.
