Platypnea Orthodeoxia Syndrome Secondary to a Persistent Eustachian Valve.

Platypnea-Orthodeoxia syndrome (POS) is a rare and poorly understood syndrome characterized by platypnea and oxygen desaturation in the upright position that is relieved by recumbency. Here, we report a case of an 84-year-old woman who had chronic hypoxia in an upright position despite using home oxygen. The patient presented for hypoxia evaluation and was noted to have a restrictive pattern on pulmonary function tests (PFT). An echocardiogram showed a prominent eustachian valve extending from inferior to superior vena cava with contrast approaching the interatrial septum. The patient had a complete resolution of her platypnea following the closure of the patent foramen ovale.

Informant-based hearing difficulties and the risk for mild cognitive impairment and dementia.

BACKGROUND: hearing loss has been associated with mild cognitive impairment (MCI) and dementia. Studies have not assessed whether hearing difficulties (HD) that interfere with daily activities as reported by partners can be a marker for increased risk for cognitive decline and impairment. OBJECTIVE: to assess the cross-sectional and longitudinal associations between informant-based HD, which interfere with daily activities and the risk for MCI and dementia. METHODS: the study included 4812 participants without dementia, enrolled in the Mayo Clinic Study of Aging (mean age (SD) 73.7 (9.6) years) with cognitive evaluation and informant-based report on participant's HD that interfere significantly with daily activities at baseline and for every 15 months. Cox proportional hazards models (utilising time-dependent HD status and age as the time scale) were used to examine HD and the risk for MCI or dementia, and mixed-effects models (allowing for random subject-specific intercepts and slopes) were used to examine the relationship between HD and cognitive decline. RESULTS: about, 981 participants had HD and 612 (12.7%) had prevalent MCI at baseline; 759 participants developed incident MCI and 273 developed incident dementia. In cognitively unimpaired participants at baseline, those with HD had higher risk for MCI (hazard ratio [HR] = 1.29, 95% confidence interval [CI] (1.10, 1.51), P = 0.002; adjusting for sex, years of education). In participants without dementia, those with HD had higher risk for dementia (HR: 1.39, 95% CI, (1.08-1.79), P = 0.011; adjusting sex and education). In individuals with MCI, HD was associated with modestly greater cognitive decline. CONCLUSIONS: informant-based HD was associated with increased risk for MCI and dementia.

Medications Affecting the Biochemical Conversion to Type 2 Diabetes: A Systematic Review and Meta-Analysis.

CONTEXT: The extent to which some pharmacological interventions reduce or increase the risk of biochemical conversion to type 2 diabetes mellitus (T2DM) in at-risk individuals is unclear. METHODS: We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Scopus through 24 August 2017 for randomized controlled trials evaluating the effect of drugs suspected to modify the risk of biochemical conversion to T2DM. RESULTS: We included 43 trials with 192,156 subjects (mean age, 60 years; 56% men; mean body mass index, 30.4 kg/m2). α-Glucosidase inhibitors, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, metformin, orlistat, phentermine/topiramate, and pioglitazone significantly reduced the risk of biochemical conversion to T2DM, whereas statins and nateglinide increased the risk. There was insufficient direct evidence regarding the effects of sulfonylureas, glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, and sodium-glucose cotransporter-2 inhibitors. Most trials were brief and evaluated this outcome during treatment without a withdrawal or washout period. CONCLUSIONS: Several drugs modify the risk of biochemical conversation to T2DM, although whether this effect is persistent and clinically relevant is unclear. Future studies need to focus on cardiovascular disease prevention, mortality, and patient-important outcomes instead of biochemical conversion to T2DM.

Epidemiology of Pediatric Critical Illness in a Population-Based Birth Cohort in Olmsted County, MN.

OBJECTIVES: Investigations of pediatric critical illness typically focus on inpatient cohorts drawn from wide referral areas and diverse healthcare systems. Cohorts amenable to investigating the full spectrum of critical illness as it develops within a community have yet to be studied in the United States. Our objective was to provide the first epidemiologic report of the incidence and presentation of pediatric critical illness within a U.S. population-based birth cohort. DESIGN: Retrospective cohort study. SETTING: A geographically defined community (Olmsted, MN) with medical record linkage across all health systems. All ICU services are provided within a single children's hospital. PATIENTS: A birth cohort of children (n =9,441) born 2003-2007 in Olmsted County, MN. MEASUREMENTS AND MAIN RESULTS: During the study period, there were a total of 15,277 ICU admissions to Mayo Clinic Children's Hospital. A total of 577 birth cohort children accounted for 824 of these admissions during the 61,770 person-years of follow-up accumulated. Incidence of first-time ICU admission was 9.3 admits per 1,000 person-years. Admission rates were highest in the first year of life and then declined steadily. Respiratory problems were among the most common reasons for admission at any age and diagnoses reflect changes in health risk factors as children grow and develop over time. After 1 year old, a majority of children admitted have preexisting chronic comorbidities and/or prior ICU stays. In-hospital mortality occurred exclusively in children admitted prior to 5 days of age (n = 4). Seven children died after hospital discharge. CONCLUSIONS: This is the first report characterizing critical illness within a population-based birth cohort of U.S. children. The results demonstrate the changing incidence, presentation, and healthcare requirements associated with critical illness across the developmental spectrum as a population of children ages.

Bypass surgery versus endovascular interventions in severe or critical limb ischemia.

OBJECTIVE: Critical limb ischemia is associated with a significant morbidity and mortality. We systematically reviewed the evidence to compare bypass surgery with endovascular revascularization in patients with critical limb ischemia. METHODS: We systematically searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL, and Scopus through October 2014 for comparative studies (randomized and nonrandomized). Predefined outcomes of interest were mortality, major amputation, patency, and wound healing. We pooled odds ratios (ORs) of the outcomes of interest using the random-effects model. RESULTS: Nine studies that enrolled 3071 subjects were included. There was no significant difference in mortality (OR, 0.72; 95% confidence interval [CI], 0.44-1.16) or amputation (OR, 1.2; 95% CI, 0.87-1.65). Bypass surgery was associated with higher primary patency (OR, 2.50; 95% CI, 1.25-4.99) and assisted primary patency (OR, 3.39; 95% CI, 1.53-7.51). The quality of evidence was low for mortality and amputation outcomes and moderate for patency outcomes. CONCLUSIONS: Low quality of evidence due to imprecision and heterogeneity suggests that bypass surgery and endovascular approaches may have similar effect on mortality and major amputations. However, better primary and primary assisted patency can be expected with surgery.

Pretransplant frailty is associated with decreased survival after lung transplantation.

BACKGROUND: Frailty is a condition of increased vulnerability to adverse health outcomes. Although frailty is an important prognostic factor for many conditions, the effect of frailty on mortality in lung transplantation is unknown. Our objective was to assess the association of frailty with survival after lung transplantation. METHODS: We performed a retrospective cohort analysis of all adult lung transplant recipients at our institution between 2002 and 2013. Frailty was assessed using the frailty deficit index, a validated instrument that assesses cumulative deficits for up to 32 impairments and measures the proportion of deficits present (with frailty defined as >0.25). We examined the association between frailty and survival, adjusting for age, sex, and bilateral (vs single) lung transplant using Cox proportional hazard regression models. RESULTS: Among 144 lung transplant patients, 102 (71%) completed self-reported questionnaires necessary to assess the frailty deficit index within 1 year before lung transplantation. Frail patients (n = 46) had an increased risk of death, with an adjusted hazard ratio (HR) of 2.24 (95% confidence interval [CI], 1.22-4.19; p = 0.0089). Frailty was not associated with an increased duration of mechanical ventilation (median, 2 vs 2 days; p = 0.26), intensive care unit length of stay (median, 7.5 vs 6 days; p = 0.36) or hospital length of stay after transplantation (median, 14 vs 10.5 days; p = 0.26). CONCLUSIONS: Pre-transplant frailty was independently associated with decreased survival after lung transplantation. Pre-transplant frailty may represent an important area for intervention to improve candidate selection and lung transplant outcomes.

Nonrevascularization-based treatments in patients with severe or critical limb ischemia.

OBJECTIVE: The aim of this systematic review was to synthesize the existing evidence about various nonrevascularization-based therapies used to treat patients with severe or critical limb ischemia (CLI) who are not candidates for surgical revascularization. METHODS: We systematically searched multiple databases through November 2014 for controlled randomized and nonrandomized studies comparing the effect of medical therapies (prostaglandin E1 and angiogenic growth factors) and devices (pumps and spinal cord stimulators). We report odds ratios (ORs) and 95% confidence intervals (CIs) of the outcomes of interest pooling data across studies using the random effects model. RESULTS: We included 19 studies that enrolled 2779 patients. None of the nonrevascularization-based treatments were associated with a significant effect on mortality. Intermittent pneumatic compression (OR, 0.14; 95% CI, 0.04-0.55) and spinal cord stimulators (OR, 0.53; 95% CI, 0.36-0.79) were associated with reduced risk of amputation. A priori established subgroup analyses (combined vs single therapy; randomized vs nonrandomized) were not statistically significant. CONCLUSIONS: Very low-quality evidence, mainly due to imprecision and increased risk of bias, suggests that intermittent pneumatic compression and spinal cord stimulators may reduce the risk of amputations. Evidence supporting other medical therapies is insufficient.

The natural history of untreated severe or critical limb ischemia.

OBJECTIVE: Critical limb ischemia (CLI) is associated with high morbidity and mortality. Because most patients with CLI will eventually undergo some type of revascularization, the natural history of CLI is not well defined, although it is important to know when patients decide to pursue treatment. METHODS: We systematically searched multiple databases for controlled and uncontrolled studies of patients with CLI who did not receive revascularization with a minimum follow-up of ≥1 year. Predefined outcomes of interest were mortality, major amputation, and wound healing. Random-effects meta-analysis was used to pool cumulative incidence across studies. RESULTS: We identified 13 studies enrolling 1527 patients. During a median follow-up of 12 months, all-cause mortality rate was 22% (confidence interval [CI], 12%-33%) and major amputation rate was 22% (CI, 2%-42%). Worsened wound or ulcer was found at 35% (CI, 10%-62%). There was a trend toward improvement in mortality and amputation rate in studies done after 1997. The quality of evidence was low because of increased risk of bias and inconsistency. CONCLUSIONS: Mortality and major amputations are common in patients who have untreated CLI during a median follow-up of 1 year, although these outcomes have improved in recent times.

The incremental benefit of functional imaging in pheochromocytoma/paraganglioma: a systematic review.

Computed tomography (CT) and magnetic resonance imaging (MRI) are the major imaging modalities used for the localization of catecholamine-producing tumors (pheochromocytoma and paraganglioma). Functional imaging (FI) offers an alternative approach to localize, evaluate, and stage these tumors. Our objective was to describe the additive benefit of FI studies for patients with pheochromocytoma and paraganglioma (PPG) who have undergone MRI or CT scan evaluation. We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus from database inception through June 2012 for studies that included patients with biochemically proven PPGs who underwent CT or MRI and additional FI for the localization of PPGs. We included 32 studies enrolling a total of 1,264 patients with a mean age of 43-years old. The studies were uncontrolled and evaluated six FI modalities. FI tests provided small additive value to CT/MRI, aiding in the localization of only 24/1,445 primary cases (1.4 %) and 28/805 metastatic cases (3.5 %). In metastatic cases, 6-[F-18]fluoro-L-dihydroxyphenylalanine (DOPA) and fluorodopamine-PET (FDA) were the FI tests most successful at identifying disease missed by CT/MRI, providing additional benefit in 6/60 (10 %) and 5/78 (6.4 %) cases, respectively. No clinically significant findings were observed in any of the predefined subgroups. No study evaluated the impact of FI on the completeness of surgical resection or other patient-important outcomes. Observational evidence suggests that FI tests have a limited additional role in patients with PPGs who have undergone CT/MRI evaluation. However, the role of FI tests in specific subgroups of patients with atypical presentations (metastatic, extra-adrenal) as well as the use of hybrid FI tests should be explored. Further research should also evaluate the impact of FI tests on patient-important outcomes.

Clinical review: Drugs commonly associated with weight change: a systematic review and meta-analysis.

CONTEXT: Various drugs affect body weight as a side effect. OBJECTIVE: We conducted this systematic review and meta-analysis to summarize the evidence about commonly prescribed drugs and their association with weight change. DATA SOURCES: MEDLINE, DARE, and the Cochrane Database of Systematic Reviews were searched to identify published systematic reviews as a source for trials. STUDY SELECTION: We included randomized trials that compared an a priori selected list of drugs to placebo and measured weight change. DATA EXTRACTION: We extracted data in duplicate and assessed the methodological quality using the Cochrane risk of bias tool. RESULTS: We included 257 randomized trials (54 different drugs; 84 696 patients enrolled). Weight gain was associated with the use of amitriptyline (1.8 kg), mirtazapine (1.5 kg), olanzapine (2.4 kg), quetiapine (1.1 kg), risperidone (0.8 kg), gabapentin (2.2 kg), tolbutamide (2.8 kg), pioglitazone (2.6 kg), glimepiride (2.1 kg), gliclazide (1.8 kg), glyburide (2.6 kg), glipizide (2.2 kg), sitagliptin (0.55 kg), and nateglinide (0.3 kg). Weight loss was associated with the use of metformin (1.1 kg), acarbose (0.4 kg), miglitol (0.7 kg), pramlintide (2.3 kg), liraglutide (1.7 kg), exenatide (1.2 kg), zonisamide (7.7 kg), topiramate (3.8 kg), bupropion (1.3 kg), and fluoxetine (1.3 kg). For many other remaining drugs (including antihypertensives and antihistamines), the weight change was either statistically nonsignificant or supported by very low-quality evidence. CONCLUSIONS: Several drugs are associated with weight change of varying magnitude. Data are provided to guide the choice of drug when several options exist and institute preemptive weight loss strategies when obesogenic drugs are prescribed.

Testing for germline mutations in sporadic pheochromocytoma/paraganglioma: a systematic review.

BACKGROUND: The presence of germline mutations in sporadic pheochromocytomas and paragangliomas (SPPs) may change the clinical management of both index patients and their family members. However, the frequency of germline mutations in SPPs is unknown. OBJECTIVE: To describe the frequency of germline mutations in SPPs and to determine the value of testing index patients and their family members for these mutations. METHODS: We searched databases through June 2012 for observational studies of patients with SPPs who underwent germline genetic testing. The criteria used to define sporadic tumours were (i) the absence of a family history of PCC/PG, (ii) the absence of syndromic features, (iii) the absence of bilateral disease and (iv) the absence of metastatic disease. RESULTS: We included 31 studies including 5031 patients (mean age 44). These patients received tests for any of these ten mutations: SDHAF2, RET, SDHD, SDHB, SDHC, VHL, TMEM127, MAX, Isocitrate Dehydrogenase Mutation (IDH) and NF1. The overall frequency of germline mutation in SPP was 551 of 5031 or 11%; when studies with patients fulfilling four criteria for sporadic tumours were used, the frequency was 171 of 1332 or 13%. The most common germline mutation was SDHB 167 of 3611 (4·6%). Little outcome data were available to assess the benefits of genetic testing in index cases and family members. CONCLUSIONS: The frequency of germline mutations in SPPs is approximately 11-13% and the most common mutations affect less than 1 in 20 patients. The value of testing for germline mutations in patients with SPPs and their family members is unknown, as the balance of potential benefits and harms remains unclear.

PTSD in post-road traffic accident patients requiring hospitalization in Indian subcontinent: A review on magnitude of the problem and management guidelines.

Traumatic events after a road traffic accident (RTA) can be physical and/or psychological. Posttraumatic stress disorder (PTSD) is one of the major psychological conditions which affect accident victims. Psychological issues may not be addressed in the emergency department(ED) immediately. There have been reports about a mismatch between the timely referrals from ED to occupational or primary care services for these issues. If left untreated, there may be adverse effects on quality of life (QOL) and work productivity. Hospital expenses, loss of income, and loss of work could create a never ending cycle for financial difficulties and burden in trauma victims. The aim of our review is to address the magnitude of PTSD in post-RTA hospitalized patients in Indian subcontinent population. We also attempted to emphasis on few management guidelines. A comprehensive search was conducted on major databases with Medical Subject Headings (MeSH) term 'PTSD or post-traumatic stress' and Emergency department and vehicle or road or highway or automobile or car or truck or trauma and India. Out of 120 studies, a total of six studies met our inclusion criteria and were included in the review. Our interpretation of the problem is that; hospital expenditure due to trauma, time away from work during hospitalization, and reduction in work performance, are three major hits that can lead RTA victims to financial crisis. Proposed management guidelines are; establish a coordinated triage, implementing a screening tool in the ED, and provide psychological counseling.

Clinical review: The benefits and harms of systemic dehydroepiandrosterone (DHEA) in postmenopausal women with normal adrenal function: a systematic review and meta-analysis.

CONTEXT: Exogenous dehydroepiandrosterone (DHEA) therapy has been proposed to replenish the depletion of endogenous DHEA and its sulfate form, which occurs with advancing age and is thought to be associated with loss of libido and menopausal symptoms. OBJECTIVE: We conducted a systematic review and meta-analysis to summarize the evidence supporting the use of systemic DHEA in postmenopausal women with normal adrenal function. METHODS: We searched MEDLINE, EMBASE, PsycInfo, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through January 2014. Pairs of reviewers, working independently, selected studies and extracted data from eligible randomized controlled trials (RCTs). We used the random-effects model to pool across studies and evaluated heterogeneity using the I(2) statistic. RESULTS: We included 23 RCTs with moderate to high risk of bias enrolling 1188 women. DHEA use was not associated with significant improvement in libido or sexual function (standardized mean difference, 0.35; 95% confidence interval, -0.02 to 0.73; P value = .06; I(2) = 62%). There was also no significant effect of DHEA on serious adverse effects, serum lipids, serum glucose, weight, body mass index, or bone mineral density. This evidence warranted low confidence in the results, mostly due to imprecision, risk of bias, and inconsistency across RCTs. CONCLUSIONS: Evidence warranting low confidence suggests that DHEA administration does not significantly impact sexual symptoms or selected metabolic markers in postmenopausal women with normal adrenal function.

Clinical review: The benefits and harms of systemic testosterone therapy in postmenopausal women with normal adrenal function: a systematic review and meta-analysis.

CONTEXT: The use of T has been suggested to improve women's health during the postmenopausal period. OBJECTIVE: We conducted a systematic review and meta-analysis of randomized trials to summarize the best available evidence regarding the benefits and harms of systemic T in postmenopausal women with normal adrenal function. METHODS: A comprehensive search of MEDLINE, EMBASE, PsycInfo, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, EBSCO CINAHL, and Scopus was conducted through January 2014. We conducted study selection, data extraction, and appraisal in duplicate. Random-effects meta-analysis was used to pool results. RESULTS: We identified 35 randomized trials (n = 5053) at a moderate risk of bias. T use was associated with statistically significant improvement in various domains of sexual function and personal distress in postmenopausal women, although the majority of the trials did not have specific or contemporary diagnostic criteria for androgen deficiency in women. T use was also associated with a reduction in total cholesterol, triglyceride, and high-density lipoprotein and an increase in low-density lipoprotein and in the incidence of acne and hirsutism. No significant effect was noted on anthropometric measures and bone density. Long-term safety data were sparse, and the quality of such evidence was low. CONCLUSION: Despite the improvement in sexual function associated with T use in postmenopausal women, long-term safety data are lacking.

Dual computer monitors to increase efficiency of conducting systematic reviews.

OBJECTIVE: Systematic reviews (SRs) are the cornerstone of evidence-based medicine. In this study, we evaluated the effectiveness of using two computer screens on the efficiency of conducting SRs. STUDY DESIGN AND SETTING: A cohort of reviewers before and after using dual monitors were compared with a control group that did not use dual monitors. The outcomes were time spent for abstract screening, full-text screening and data extraction, and inter-rater agreement. We adopted multivariate difference-in-differences linear regression models. RESULTS: A total of 60 SRs conducted by 54 reviewers were included in this analysis. We found a significant reduction of 23.81 minutes per article in data extraction in the intervention group relative to the control group (95% confidence interval: -46.03, -1.58, P = 0.04), which was a 36.85% reduction in time. There was no significant difference in time spent on abstract screening, full-text screening, or inter-rater agreement between the two groups. CONCLUSION: Using dual monitors when conducting SRs is associated with significant reduction of time spent on data extraction. No significant difference was observed on time spent on abstract screening or full-text screening. Using dual monitors is one strategy that may improve the efficiency of conducting SRs.

Comparative systematic review and meta-analysis of compression modalities for the promotion of venous ulcer healing and reducing ulcer recurrence.

OBJECTIVE: This was a systematic review of the literature to determine which compression method is superior in promoting ulcer healing and reducing recurrence in patients with lower extremity venous ulcer disease. METHODS: We conducted a comprehensive search of multiple databases for randomized and nonrandomized comparative studies from 1990 to December 2013. RESULTS: We identified 36 studies and two Cochrane systematic reviews. Many studies had moderate risk of bias. We found no overall difference between compression stockings vs compression bandages with respect to ulcer healing, time to ulcer healing, or ulcer recurrence outcomes. When we compared stockings vs short stretch bandages, stockings were superior with respect to ulcer healing. However, stockings compared with four-layer systems showed no difference in ulcer healing outcomes. When four-layer systems were compared with compression with less than four layers, there was also no significant difference in ulcer healing outcomes. Similarly, short stretch bandages were not superior to long stretch bandages with respect to ulcer healing, time to ulcer healing, or ulcer recurrence. One Cochrane review presented many additional comparisons and reported increased wound healing with compression compared with no compression, with multicomponent systems over single component systems, and compression systems with an elastic component over no elastic component. Another Cochrane review demonstrated a reduction in recurrence with compression in patients with healed ulcers. CONCLUSIONS: At least moderate-quality evidence supports compression over no compression, multicomponent systems over single component systems, and systems with an elastic component over those without. We did not find significant differences with respect to ulcer healing outcomes for other comparisons. Low-quality evidence supports the effect of compression on ulcer recurrence.

Systematic review and meta-analysis of surgical interventions versus conservative therapy for venous ulcers.

OBJECTIVE: This goal of this study was to systematically review the literature to determine if surgical intervention (open or endovascular) is superior to compression alone with respect to ulcer healing, ulcer recurrence, and time to ulcer healing in patients with lower extremity venous ulcer disease. METHODS: We conducted a comprehensive search of multiple databases for randomized controlled trials (RCTs) and comparative observational studies from 1990 to December 2013. The interventions of interest were any open or endovascular surgical interventions on the venous system in the lower extremity compared with compression alone. RESULTS: We included 11 studies (seven RCTs and four observational studies) with moderate to increased risk of bias. The meta-analysis of all studies demonstrated increased healing rate (pooled risk ratio [RR], 1.06; 95% confidence interval [CI], 1.00-1.13; I(2) = 10%) and lower risk of recurrence (RR, 0.54; 95% CI, 0.34-0.85; I(2) = 27%) with open surgical procedures compared with compression. However, the meta-analysis of only RCTs showed no difference, possibly due to imprecision. The meta-analysis of three RCTs showed no difference in time to ulcer healing, -0.41 (95% CI, -0.89 to 0.07). Two studies of endovascular surgical procedures compared with compression showed no significant difference in ulcer healing (RR, 1.65; 95% CI, 0.43-6.32). One study of open surgical venous ligation and stripping compared with endovenous laser also showed no significant difference in ulcer recurrence (RR, 0.83; 95% CI, 0.21-3.27). CONCLUSIONS: Open surgical interventions may improve lower extremity venous ulcer healing. The quality of this evidence is low because the analysis was dominated by the results of observational studies. The current evidence does not definitively support the superiority of endovascular surgical interventions compared with compression alone.

Improving patient-centered care: agenda-setting in occupational medicine.

OBJECTIVE: To improve patient satisfaction with care at an occupational medicine clinic by promoting agenda-setting before the visit. METHODS: We distributed agenda-setting form to 77 randomly selected patients attending an occupational health clinic and used another randomly selected sample of 36 patients as control group. Patients completed a survey regarding the acceptability of this procedure and whether they felt clinicians addressed their important concerns. RESULTS: Most patients found the form helpful (73%) and wanted it offered in future visits (74%). There was no statistically significant difference in terms of the proportion of patients expressing greatest satisfaction by answering, "strongly agree" (intervention [86%], control [97%]; odds ratio, 0.17; 95% confidence interval, 0.02 to 1.38; P = 0.06). CONCLUSION: Agenda-setting can improve patient experience before occupational visits but does not improve postvisit satisfaction.

Clinical review. Risk factors for low bone mass-related fractures in men: a systematic review and meta-analysis.

CONTEXT: Testing men at increased risk for osteoporotic fractures has been recommended. OBJECTIVE: The aim of this study was to estimate the magnitude of association and quality of supporting evidence linking multiple risk factors with low bone mass-related fractures in men. DATA SOURCES: We searched MEDLINE, EMBASE, Web of Science, SCOPUS and Cochrane CENTRAL through February 2010. We identified further studies by reviewing reference lists from selected studies and reviews. STUDY SELECTION: Eligible studies had to enroll men and quantitatively evaluate the association of risk factors with low bone density-related fractures. DATA EXTRACTION: Reviewers working independently and in duplicate determined study eligibility and extracted study description, quality, and outcome data. DATA SYNTHESIS: Fifty-five studies provided data sufficient for meta-analysis. The quality of these observational studies was moderate with fair levels of multivariable adjustment and adequate exposure and outcome ascertainment. Statistically significant associations were established for age, low body mass index, current smoking, excessive alcohol use, chronic corticosteroid use, history of prior fractures, history of falls, history of hypogonadism, history of stroke, and history of diabetes. Statistical heterogeneity of the meta-analytic estimates of all associations was significant except for chronic corticosteroid use. None of these associations were of large magnitude (i.e. adjusted odds ratios were generally <2). No evidence supporting a particular effective testing or screening strategy was identified. CONCLUSIONS: Multiple risk factors for fractures in men were identified, but their usefulness for stratifying and selecting men for bone density testing remains uncertain.
