Reliable Rapid Assay for Gonorrhea and Chlamydia in the Emergency Department.

BACKGROUND: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are common sexually transmitted infections seen in the emergency department (ED). Due to an inability to reliably make accurate diagnosis by physical examination, concern for unreliable follow-up, and current delays in diagnostic nucleic acid amplification testing (NAAT), presumptive treatment active against CT and NG, as described by Centers for Disease Control clinical practice guidelines, is often performed. OBJECTIVES: The purpose of this study was to determine whether a rapid, urine NAAT performed in the ED is noninferior in its diagnostic sensitivity compared with a traditional, swab NAAT assay. METHODS: We performed a prospective, noninferiority study comparing two U.S. Food and Drug Administration-approved NAAT assays for CT and NG: a 90-min rapid assay, the Xpert CT/NG Assay (Cepheid, Sunnyvale, CA) using a urine sample vs. a traditional assay, the Aptima Combo 2 Assay (Gen-Probe Incorporated, San Diego, CA) using a swab sample. This study was registered on Clinicaltrials.gov (NCT02386514). RESULTS: A total of 1162 patient samples were included in the primary analysis. We observed excellent kappa agreement between assays: NG for men, 1.00 (95% confidence interval [CI] 1.00-1.00); NG for women, 0.87 (95% CI 0.79-0.94); CT for men, 0.81 (95% CI 0.59-1.00); and CT for women: 0.85 (95% CI 0.80-0.90), as well as excellent negative and positive predictive values for the rapid assay. CONCLUSION: Although the rapid Xpert CT/NG assay's diagnostic sensitivity did not meet our prespecified threshold for noninferiority, the diagnostic characteristics are robust enough to fit into a management pathway that may reduce unnecessary antibiotic use. There may be an opportunity to utilize the rapid Xpert CT/NG assay to improve accuracy of treatment in the ED.

Survival outcomes and patterns of failure in women with stage IIIC2 endometrial carcinoma.

OBJECTIVES: Para-aortic lymph node involvement in women with endometrial carcinoma (EC) is a poor prognostic factor. Many studies have included women with stage IIIC2 in cohorts of patients with advanced stage disease. The aim of this study was to analyze survival outcomes and patterns of failure in women with solely stage IIIC2 EC. METHODS: We identified women with FIGO stage IIIC2 EC who underwent surgical staging at our institution. In addition to descriptive analyses of patient demographics, tumor characteristics, and adjuvant treatment received, univariate log-rank analyses and Cox regression multivariate analyses (MVA) were performed to identify predictors of recurrence-free (RFS), disease-specific (DSS) and overall survival (OS). RESULTS: A total of 72 women were included in this study cohort. The median follow-up time was 43 months. The median number of positive para-aortic lymph nodes was one. Of the 61 women (84.7%) who received adjuvant therapy, 40 women (65.6%) received chemotherapy and radiation therapy (CRT), 17 women (27.9%) received chemotherapy alone (CT), and only 4 women (6.6%) received radiation therapy alone. Thirty-seven women (51.4%) experienced disease recurrence. Distant metastasis was the most common pattern of failure (73%). Five-year RFS, DSS, and OS were 48%, 51%, and 48%, respectively. Due to small study size, our exploratory multivariate analysis demonstrated that histologic grade was the only significant prognostic factor for DSS (p=0.03) and OS (p=0.02). The type of adjuvant therapy did not sustain its independent predictive significance for RFS, DSS and OS. CONCLUSIONS: Our findings suggest that almost half of women with stage IIIC2 can be cured with surgical staging and adjuvant therapies. The most common pattern of failure was distant metastasis calling for further optimization of systemic therapy.

Risk Factors for 30-Day Mortality in Patients with Methicillin-Resistant Staphylococcus aureus Bloodstream Infections.

OBJECTIVES: Methicillin-resistant Staphylococcus aureus (MRSA) blood stream infections (BSI) are a major health care problem accounting for a large percentage of nosocomial infections. The aim of this study was to identify risk factors associated with 30-day mortality in patients with MRSA BSI. METHODS: This was a retrospective study performed in Southeast Michigan. Over a 9- year period, a total of 1,168 patients were identified with MRSA BSI. Patient demographics and clinical data were retrieved and evaluated using electronic medical health records. RESULTS: 30-day mortality during the 9-year study period was 16%. Significant risk factors for 30-day mortality were age, cancer, heart disease, neurologic disease, nursing home residence and Charlson score >3 with Odds Ratio (OR) of 1.03 (CI 1.02-1.04), 2.29 (CI 1.40-3.75), 1.78 (CI 1.20-2.63), 1.65 (CI 1.08-2.25), 1.66 (CI 1.02 - 2.70) and 1.86 (CI 1.18 - 2.95) correspondingly. Diabetes mellitus, peripheral vascular disease (PVD), and readmission were protective factors for 30-day mortality with OR of 0.53 (CI 0.36-0.78), 0.46 (CI 0.26-0.84) and 0.13 (CI0.05 - 0.32) respectively. CONCLUSIONS: Our study identified significant risk factors for 30-day mortality in patients with MRSA BSI. Interestingly, diabetes mellitus, PVD and readmission were protective effects on 30-day mortality. There was no statistically significant variability in 30-day mortality over the 9-year study period.

Gonorrhea and chlamydia in the emergency department: Continued need for more focused treatment for men, women and pregnant women.

INTRODUCTION: Delay in current nucleic acid amplification testing for Neisseria gonorrhoeae and Chlamydia trachomatis has led to recommendations for presumptive treatment in patients with concern for infection and unreliable follow-up. In the urban setting, it is assumed that many patients have unreliable follow-up, therefore presumptive therapy is thought to be used frequently. We sought to measure the frequency of disease and accuracy of presumptive treatment for these infections. METHODS: This was an observational cohort study performed at an urban academic Level 1 trauma center ED with an annual census of 95,000 visits per year. Testing was performed using the APTIMA Unisex swab assay (Gen-Probe Incorporated, San Diego, CA). Presumptive therapy was defined as receiving treatment for both infections during the initial encounter without confirmation of diagnosis. RESULTS: A total of 1162 patients enrolled. Infection was present in 26% of men, 14% of all women and 11% of pregnant women. Despite high frequency of presumptive treatment, >4% of infected patients in each category went untreated. CONCLUSION: Inaccuracy of presumptive treatment was common for these sexually transmitted infections. There is an opportunity to improve diagnostic accuracy for treatment.

The impact of lymphadenectomy on survival endpoints in women with early stage uterine endometrioid carcinoma: A matched analysis.

OBJECTIVES: The role of pelvic lymphadenectomy (LA) in women with stage I endometrial carcinoma (EC) is controversial. The objective of this study is to investigate the prognostic impact of LA on survival endpoints in matched cohorts of women with stage I EC solely of endometrioid histology. Survival endpoints included recurrence-free (RFS), disease-specific (DSS) and overall survival (OS). METHODS AND MATERIALS: Patients with FIGO stage I EC who underwent hysterectomy with LA as part of their surgical staging between 1/1990 and 6/2015 were matched to a similar group that underwent hysterectomy without lymphadenectomy (NLA), based on stage, grade and adjuvant management. Univariate and multivariate modeling with Cox regression analysis was carried out for predictors of survival endpoints. RESULTS: 870 women constituted the study cohort (435 in each group). Median number of dissected lymph node in the LA group was 9 (range, 5-75). There was no statistically significant difference between the two groups in regards to 5-year OS (87.2% for LA vs. 91.7% for NLA) (p=0.36), DSS 97.7% vs. 98% (p=0.54) and RFS (93.7% vs. 90% (p=0.08), respectively. Lymphadenectomy was not a predictor of any of the studied survival endpoints. On multivariate analysis for the entire cohort, older age, deep myometrial invasion and higher tumor grade were predictors of worse RFS. For DSS, higher tumor grade, lower uterine segment (LUS) involvement and FIGO stage IB were significant predictors of worse outcome. For OS, older age and LUS involvement were the only two independent predictors for shorter OS. CONCLUSIONS: After matching for FIGO stage, grade and adjuvant management, it appears that lymphadenectomy in women with stage I EC does not impact survival endpoints.

Stereotactic Body Radiotherapy for Elderly Patients With Medically Inoperable Pancreatic Cancer.

OBJECTIVES: People over the age of 75 years account for approximately 40% of patients diagnosed with pancreatic cancer, many with comorbidities that may limit their treatment options. This study reports on the use of stereotactic body radiation therapy (SBRT) in this population. MATERIALS AND METHODS: Twenty consecutively treated patients over the age of 75 with pathologically proven localized pancreatic cancer were included in this retrospective review. All had been evaluated by a multidisciplinary team as unable to tolerate surgery or combined chemoradiation therapy. Patient outcomes were analyzed to determine the safety and efficacy of SBRT in this elderly cohort. RESULTS: The median age was 83.2 years (minimum 77 y, maximum 90 y). Eighteen patients were treated at time of initial diagnosis, and 2 for recurrence after surgery. Eleven (55%) of the patients had an Adult Comorbidity Evaluation-27 comorbidity index score of 3 (severe) and 6 (30%) had a score of 2 (moderate). Fourteen patients were treated with 35 Gy in 5 fractions, 5 with 30 Gy in 5 fractions, and 1 patient with 36 Gy in 3 fractions. Seven (35%) patients had common terminology criteria for adverse events (CTCAE) V4.0 toxicity grade of 1-2, and 3 patients had a CTCAE V4.0 toxicity grade of 3-4, 2 with dehydration, and 1 had episodes of gastrointestinal bleeding. Three patients recurred locally, 10 had distant metastases, 4 of whom were found on the first posttreatment scan. Median overall survival was 6.4 months (95% confidence interval, 3.5-10.8 mo). Median recurrence-free survival was 6.8 months (95% confidence interval, 1.3-23.5 mo). Two patients survived >23 months. CONCLUSION: SBRT for pancreatic cancer appears to be a safe and effective method for treatment of elderly patients, even in the setting of severe comorbidities.

Predictive Capacity of 3 Comorbidity Indices in Estimating Survival Endpoints in Women With Early-Stage Endometrial Carcinoma.

OBJECTIVE: The negative impact of comorbidity on survival in women with endometrial carcinoma (EC) is well-known. Few validated comorbidity indices are available for clinical use, such as the Charlson Comorbidity Index (CCI), the Age-Adjusted CCI (AACCI), and the Adult Comorbidity Evaluation-27 (ACE-27). The aim of the study is to determine which index best correlates with survival endpoints in women with EC. MATERIALS AND METHODS: We identified 1132 women with early-stage EC treated at an academic center. Three scores were calculated for each patient using CCI, AACCI, and ACE-27 at the time of hysterectomy. Univariate and multivariable modeling was used to determine predictors of survival. RESULTS: For each of the studied comorbidity indices, the highest scores were significantly correlated with poorer overall survival. The hazard ratio of death from any cause was 3.92 for AACCI, 2.25 for CCI, and 1.57 for ACE-27. All 3 indices were independent predictors of overall survival with a P value of less than 0.001 on multivariate analysis. In addition, lymphovascular space invasion, lower uterine segment involvement, and tumor grade were predictors of overall survival. Lymphovascular space invasion, grade (P < 0.001), and high AACCI score were the only significant predictors of recurrence-free survival (RFS). Lymphovascular space invasion and tumor grade were the only 2 predictors of disease-specific survival. CONCLUSIONS: Although all 3 studied comorbidity indices were significant predictors of overall survival in women with early-stage EC, AACCI showed a stronger association. It should be considered for evaluating comorbidity in women with early-stage EC.

Identifying disparity in emergency department length of stay and admission likelihood.

BACKGROUND: To assess whether insurance status has an effect on emergency department (ED) length of stay (LOS) and likelihood for admission or transfer to an operating room. METHODS: This was a retrospective cross-sectional study of all encounters from January 2011 through October 2013 at an urban, academic trauma center. Analysis included multi-variable linear regression for ED LOS and logistic regression for the likelihood of admission. RESULTS: Overall, 201 535 patients met the inclusion criteria, for which the mean age was 43.8 years, 55.9% were female, 23.4% were uninsured and 8% were of non-black race. Admission rate was 24.5% and operative rate was 1.4%. After adjusting for age, sex, triage acuity and race, the presence of insurance coverage was associated with an increased ED LOS of 575 (95%CI 552-598) vs. 567 (95%CI 543-591) minutes (P<0.01) among admitted patients and a decreased ED LOS of 456 (95%CI 381-531) vs. 499 (95%CI 423-575) minutes (P<0.01) among those transferred to an operating room. Adjusting for these same predictors, insured status remained a predictor for admission (odds ratio 1.24, 95%CI 1.20-1.28, P<0.01) and a negative predictor for transfer to the operating room (odds ratio 0.84, 95%CI 0.77-0.92, P<0.01). CONCLUSION: The insured experienced a clinically insignificant increase in ED LOS when admitted and a 43-minute decrease in ED LOS when being transferred to the operating room. The insured were more likely to be admitted and less likely to be transferred to an operating room.

Identifying a need for more focused treatment of chlamydia and gonorrhoea in the emergency department.

The indolent nature of chlamydia and gonorrhoea, along with the time delay associated with current diagnostic testing, makes definitive diagnosis while in the emergency department impossible. We therefore sought to determine the proportion of patients who receive accurate, presumptive antimicrobial treatment for these infections. A retrospective chart review was performed on all patient encounters that underwent chlamydia and gonorrhoea testing at an urban emergency department during a single month in 2012. Each encounter was reviewed for nucleic acid amplification test results and whether presumptive antibiotics were given during the initial visit. A total of 639 patient encounters were reviewed; 87.2% were female and the mean age was 26.7 years. Chlamydia was present in 11.1%, with women and men having similar infection rates: 10.6% vs. 14.6% (p = 0.277). Gonorrhoea was present in 5.0%, with a lower prevalence among women than men: 3.2% vs. 17.1% (p < 0.001). Women received presumptive treatment less often than men: 37.7% vs. 82.9% (p < 0.001). Presumptive treatment was less accurate in women than men: 7.9% vs. 25.6% (p < 0.001). After combining genders, 10.2% received accurate presumptive treatment; 33.3% were overtreated and 4.4% missed treatment. Presumptive treatment for chlamydia and gonorrhoea was more frequent and more accurate in men than in women. Overall, one-third of patients received unnecessary antibiotics, yet nearly 5% missed treatment. Better methods are needed for identifying patients who need treatment.

The Urban Emergency Department: A Potential Increased Occupational Hazard for Sharps-related Injuries.

OBJECTIVES: Health care workers are at risk for sharps-related injuries while working in the clinical arena. The authors sought to quantify and compare the frequency of these injuries for all health care personnel between the urban and community emergency department (ED). METHODS: A retrospective review was performed on the institutional human resources database of all self- or supervisor-reported sharps-related injuries that occurred to ED personnel in a single health system from January 2010 through September 2014. The health system was composed of a single urban academic Level I trauma center and seven community EDs, two of which were academic Level III trauma centers. Each sharps-related injury was reviewed for site of injury, job class, and type of instrument causing the injury. RESULTS: There were 171 sharps-related injuries reported during 447,986 urban and 1,350,623 community patient visits. Of the 171 injuries, 44.4% occurred to physicians, 39.2% to nurses, 12.9% to support staff, and 3.5% to physician assistants. Injuries occurred more frequently at the urban academic medical center when compared to the pooled community sites: 20.3 per 100,000 patient visits (n = 91) versus 5.9 per 100,000 patient visits (n = 80), respectively (odds ratio = 3.43, 95% confidence interval = 2.54 to 4.63, p < 0.001). They also occurred more frequently at the urban site when individually compared to each community site. CONCLUSIONS: Physicians accounted for the largest proportion of health care workers reporting sharps-related injuries. These injuries occurred more frequently in the urban ED than in the community EDs.

Lung Injury Prediction Score Is Useful in Predicting Acute Respiratory Distress Syndrome and Mortality in Surgical Critical Care Patients.

Background. Lung injury prediction score (LIPS) is valuable for early recognition of ventilated patients at high risk for developing acute respiratory distress syndrome (ARDS). This study analyzes the value of LIPS in predicting ARDS and mortality among ventilated surgical patients. Methods. IRB approved, prospective observational study including all ventilated patients admitted to the surgical intensive care unit at a single tertiary center over 6 months. ARDS was defined using the Berlin criteria. LIPS were calculated for all patients and analyzed. Logistic regression models evaluated the ability of LIPS to predict development of ARDS and mortality. A receiver operator characteristic (ROC) curve demonstrated the optimal LIPS value to statistically predict development of ARDS. Results. 268 ventilated patients were observed; 141 developed ARDS and 127 did not. The average LIPS for patients who developed ARDS was 8.8 ± 2.8 versus 5.4 ± 2.8 for those who did not (p < 0.001). An ROC area under the curve of 0.79 demonstrates LIPS is statistically powerful for predicting ARDS development. Furthermore, for every 1-unit increase in LIPS, the odds of developing ARDS increase by 1.50 (p < 0.001) and odds of ICU mortality increase by 1.22 (p < 0.001). Conclusion. LIPS is reliable for predicting development of ARDS and predicting mortality in critically ill surgical patients.

Intrafraction variability and deformation quantification in the breast.

PURPOSE: To evaluate intrafraction variability and deformation of the lumpectomy cavity (LC), breast, and nearby organs. METHODS AND MATERIALS: Sixteen left-sided postlumpectomy and 1 bilateral breast cancer cases underwent free-breathing CT (FBCT) and 10-phase 4-dimensional CT (4DCT). Deformable image registration was used for deformation analysis and contour propagation of breast, heart, lungs, and LC between end-exhale and end-inhale 4DCT phases. Respiration-induced motion was calculated via centroid analysis. Two planning target volumes (PTVs) were compared: PTV(FBCT) from the FBCT volume with an isotropic 10 mm expansion (5 mm excursion and 5 mm setup error) and PTV(4DCT) generated from the union of 4DCT contours with isotropic 5 mm margin for setup error. Volume and geometry were evaluated via percent difference and bounding box analysis, respectively. Deformation correlations between breast/cavity, breast/lung, and breast/heart were evaluated. Associations were tested between cavity deformation and proximity to chest wall and breast surface. RESULTS: Population-based 3-dimensional vector excursions were 2.5 ± 1.0 mm (range, 0.8-3.8 mm) for the cavity and 2.0 ± 0.8 mm (range, 0.7-3.0 mm) for the ipsilateral breast. Cavity excursion was predominantly in the anterior and superior directions (1.0 ± 0.8 mm and -1.8 ± 1.2 mm, respectively). Similarly, for all cases, LCs and ipsilateral breasts yielded median deformation values in the superior direction. For 14 of 17 patients, the LCs and breast interquartile ranges tended toward the anterior direction. The PTV(FBCT) was 51.5% ± 10.8% larger (P<.01) than PTV(4DCT). Bounding box analysis revealed that PTV(FBCT) was 9.8 ± 1.2 (lateral), 9.0 ± 2.2 (anterior-posterior), and 3.9 ± 1.8 (superior-inferior) mm larger than PTV(4DCT). Significant associations between breast and cavity deformation were found for 6 of 9 axes. No dependency was found between cavity deformation and proximity to chest wall or breast surface. CONCLUSIONS: Lumpectomy cavity and breast deformation and motion demonstrated large variability. A PTV(4DCT) approach showed value in patient-specific margins, particularly if robust interfraction setup analysis can be performed.

IGSF4 methylation as an independent marker of human papillomavirus-positive oropharyngeal squamous cell carcinoma.

IMPORTANCE: Human papillomavirus (HPV) is a known causative agent for oropharyngeal squamous cell carcinoma (OPSCC). Whereas it is becoming more firmly established that HPV-positive head and neck squamous cell carcinoma is associated with better survival outcomes, believed to be because of better response to chemoradiation therapy, the specific mechanisms for these improved survival outcomes remain underexplored. OBJECTIVE: To examine the relationship between HPV status and promoter methylation in an OPSCC cohort. DESIGN, SETTING, AND PARTICIPANTS: Real-time quantitative polymerase chain reaction was used to examine oncogenic HPV type 16 in a retrospective cohort of 121 patients with primary OPSCC. Aberrant promoter methylation of IGSF4, DAPK1, and ESR1 genes, known to be methylated in head and neck squamous cell carcinoma, including OPSCC, was examined by means of quantitative methylation-specific polymerase chain reaction. INTERVENTIONS: Patients received standard therapy. MAIN OUTCOMES AND MEASURES: Univariate associations between HPV and methylation were analyzed using Fisher exact tests followed by multivariable logistic regression. Cox proportional-hazards regression was used to model the risk of death given age, race, sex, HPV status, methylation, stage, smoking, and treatment. RESULTS: In univariate logistic regression analyses, HPV-positive status was significantly associated with Caucasian race (P = .02), treatment (radiotherapy only, P = .01; chemoradiotherapy, P = .007), and IGSF4 methylation (P = .005). The final multivariate logistic model, after controlling for patient characteristics (sex, age, smoking, race, and treatment) with backward variable selection among genes, retained IGSF4 methylation (OR, 4.5 [95% CI, 1.6-12.8]; P = .005), Caucasian race (OR, 2.9 [95% CI, 1.0-8.3]; P = .053), treatment (radiotherapy only vs neither: OR, 11.62 [95% CI, 2.02-66.82]; P = .02; chemoradiotherapy vs neither: OR, 11.15 [95% CI, 1.92-64.65]; P = .01), male sex (OR, 4.7 [95% CI, 1.3-17.0]; P = .02), and younger age (OR, 0.9 [95% CI, 0.90-1.0]; P = .008) as independent predictors of HPV-positive status. Cox regression modeling indicated HPV-negative status, age, male sex, smoking, and radiation treatment as independent predictors of mortality. CONCLUSIONS AND RELEVANCE: Methylation of IGSF4 is an independent predictor of HPV-positive status. DNA methylation in conjunction with HPV infection appears to play a role in OPSCC.

Recurrence patterns and survival endpoints in women with stage II uterine endometrioid carcinoma: a multi-institution study.

OBJECTIVE: There is paucity of data in regard to prognostic factors and outcome of women with 2009 FIGO stage II disease. The objective of this study was to investigate prognostic factors, recurrence patterns and survival endpoints in this group of patients. METHODS: Data from four academic institutions were analyzed. 130 women were identified with 2009 FIGO stage II. All patients underwent hysterectomy, oophorectomy and lymph node evaluation with or without pelvic and paraaortic lymph node dissections and peritoneal cytology. The Kaplan-Meier approach and Cox regression analysis were used to estimate recurrence-free (RFS), disease-specific (DSS) and overall survival (OS). RESULTS: Median follow-up was 44months. 120 patients (92%) underwent simple hysterectomy, 78% had lymph node dissection and 95% had peritoneal cytology examination. 99 patients (76%) received adjuvant radiation treatment (RT). 5-year RFS, DSS and OS were 77%, 90%, and 72%, respectively. On multivariate analysis of RFS, adjuvant RT, the presence of lymphovascular space invasion (LVSI) and high tumor grades were significant predictors. For DSS, LVSI and high tumor grades were significant predictors while older age and high tumor grade were the only predictors of OS. CONCLUSIONS: In this multi-institutional study, disease-specific survival for women with FIGO stage II uterine endometrioid carcinoma is excellent. High tumor grade, lymphovascular space invasion, adjuvant radiation treatment and old age are important prognostic factors. There was no significant difference in the outcome between patients who received vaginal cuff brachytherapy compared to those who received pelvic external beam radiation treatment.

African american women, hair care, and health barriers.

OBJECTIVES: The objective of this study was to elucidate the prevalence of hair loss among African American women; explore the psychosocial impact of hair grooming difficulties; and examine both perceptions related to physician encounters in this group and the relationship between hair grooming, physical activity, and weight maintenance. DESIGN: An anonymous retrospective and qualitative survey, the Hair Care Assessment Survey, is an 18-question novel survey instrument designed at the Henry Ford Hospital Department of Dermatology Multicultural Dermatology Center. SETTING: The Hair Care Assessment Survey was distributed at church-related functions at predominantly African American metropolitan Detroit churches. PARTICIPANTS: Two hundred African American women from metropolitan Detroit, Michigan, aged 21 to 83. MEASUREMENTS: The Hair Care Assessment Survey collected data relating to hair loss and hair care, psychosocial experiences relating to hair loss, and hair care as it relates to exercise and body weight management. Data was collected on doctor-patient hair-related medical visits and experiences with commercially available ethnic hair care products. RESULTS: More than 50 percent reported excessive hair loss. Twenty-eight percent had visited a physician to discuss hair issues, but only 32 percent felt their physician understood African American hair. Forty-five percent reported avoiding exercise because of hair concerns, and 22 percent felt that their hair impeded maintaining healthy body weight. CONCLUSION: Hair loss affects a compelling number of African American women, and a significant number express dissatisfaction in hair-related physician encounters. Additionally, hair styling problems present a serious impediment to physical activity and weight management among this already high-risk population.

Continuous bedside pressure mapping and rates of hospital-associated pressure ulcers in a medical intensive care unit.

BACKGROUND: Critically ill patients are vulnerable to the development of hospital-associated pressure ulcers (HAPUs). Positioning of patients is an essential component of pressure ulcer prevention because it off-loads areas of high pressure. However, the effectiveness of such positioning is debatable. A continuous bedside pressure mapping (CBPM) device can provide real-time feedback of optimal body position though a pressure-sensing mat that displays pressure images at a patient's bedside, allowing off-loading of high-pressure areas and possibly preventing HAPU formation. METHODS: A prospective controlled study was designed to determine if CBPM would reduce the number of HAPUs in patients treated in our medical intensive care unit. In 2 months, 422 patients were enrolled and assigned to beds equipped with or without a CBPM device. Patients' skin was assessed daily and weekly to determine the presence and progress of HAPUs. All patients were turned every 2 hours. CBPM patients were repositioned to off-load high-pressure points during turning, according to a graphic display. The number of newly formed HAPUs was the primary outcome measured. A χ(2) test was then used to compare the occurrence of HAPUs between groups. RESULTS: HAPUs developed in 2 of 213 patients in the CBPM group (0.9%; both stage II) compared with 10 of 209 in the control group (4.8%; all stage II; P = .02). CONCLUSION: Significantly fewer HAPUs occurred in the CBPM group than the control group, indicating the effectiveness of real-time visual feedback in repositioning of patients to prevent the formation of new HAPUs.

The prevalence of metabolic syndrome in patients with hidradenitis suppurativa.

BACKGROUND: Metabolic syndrome is a multifaceted disorder strongly associated with increased risk for development of cardiovascular disease. Chronic inflammatory diseases have been associated with metabolic syndrome. Hidradenitis suppurativa is a chronic inflammatory skin disease with significant physical and emotional sequelae. OBJECTIVE: We sought to investigate a possible association between hidradenitis suppurativa and metabolic syndrome. METHODS: A retrospective chart review of all dermatology clinic encounters over an 18-month period identified 366 patients with an appropriate diagnosis of hidradenitis suppurativa. A control population was created from patients seen in the same clinic during the same time period for the diagnoses of either keloids or verruca vulgaris using the matching criteria of age ±5 years, race, and gender. All participants were examined for characteristics of the metabolic syndrome as defined by the National Cholesterol Education Program Adult Treatment Program III guidelines. RESULTS: The prevalence of metabolic syndrome in patients with hidradenitis suppurativa was 50.6%, which was significantly higher than the control group at 30.2% (P < .001). LIMITATIONS: This was a retrospective review. Some participants could not be analyzed for metabolic syndrome presence as a result of missing data points. CONCLUSION: Our results indicate that patients with hidradenitis suppurativa may be at high risk for metabolic syndrome.
