Development of a multiphasic, cryptic screening protocol for body dysmorphic disorder in cosmetic dermatology.

BACKGROUND: The incidence of body dysmorphic disorder in cosmetic dermatology is high. Even though treating patients with this disorder may worsen symptoms and is fraught with potential complications, screening is low, due in part to lack of knowledge of the disorder, as well as inadequate screening tools. OBJECTIVES: To verify the probability of body dysmorphic disorder in a nonsurgical esthetic setting and determine the effect of a multiphasic screening protocol on mitigating poor outcomes in high-risk patients. METHODS: A multiphasic screening protocol for body dysmorphic disorder was distributed to a total of eight esthetic clinics in the United States. Practitioners administered an anonymous, cryptic prescreening form to all new, incoming patients aged ≥ 18 to ≤ 65 years from June 1, 2019, through September 1, 2019, followed by a second, more extensive screening questionnaire. Patients with suspected or subclinical body dysmorphic disorder could be refused treatment. RESULTS: A total of 734 initial screenings were recorded over 16 weeks. Of these, 4.2% (31/734) proceeded to the secondary screening phase; 29% (9/31) subsequently screened positive for body dysmorphic disorder. Practitioners refused to treat 77.8% (7/9) of positive screenings. Two patients out of seven who tested positive underwent a third screening and were subsequently treated with positive outcomes. CONCLUSIONS: Use of a cryptic screening protocol enables identification of individuals at risk for BDD and encourages open and continuous communication between patient and provider.

Predicting Liver Disease Risk Using a Combination of Common Clinical Markers: A Screening Model from Routine Health Check-Up.

BACKGROUND: Early detection is crucial for the prognosis of patients with autoimmune liver disease (AILD). Due to the relatively low incidence, developing screening tools for AILD remain a challenge. AIMS: To analyze clinical characteristics of AILD patients at initial presentation and identify clinical markers, which could be useful for disease screening and early detection. METHODS: We performed observational retrospective study and analyzed 581 AILD patients who were hospitalized in the gastroenterology department and 1000 healthy controls who were collected from health management center. Baseline characteristics at initial presentation were used to build regression models. The model was validated on an independent cohort of 56 patients with AILD and 100 patients with other liver disorders. RESULTS: Asymptomatic AILD individuals identified by the health check-up are increased yearly (from 31.6% to 68.0%, p < 0.001). The cirrhotic rates at an initial presentation are decreased in the past 18 years (from 52.6% to 20.0%, p < 0.001). Eight indicators, which are common in the health check-up, are independent risk factors of AILD. Among them, abdominal lymph node enlargement (LN) positive is the most significant different (OR 8.85, 95% CI 2.73-28.69, p < 0.001). The combination of these indicators shows high predictive power (AUC = 0.98, sensitivity 89.0% and specificity 96.4%) for disease screening. Except two liver or cholangetic injury makers, the combination of AGE, GENDER, GLB, LN, concomitant extrahepatic autoimmune diseases, and familial history also shows a high predictive power for AILD in other liver disorders (AUC = 0.91). CONCLUSION: Screening for AILD with described parameters can detect AILD in routine health check-up early, effectively and economically. Eight variables in routine health check-up are associated with AILD and the combination of them shows good ability of identifying high-risk individuals.

Feasibility of Brigade-Style, Multiphasic Cancer Screening in Rural Honduras.

PURPOSE: To evaluate the feasibility of brigade-style, multiphasic cancer screening in Honduras, exploring data from 3 screening events that each tested for multiple cancers on single occasions. METHODS: This series of 3 studies each used a single-arm, post-test-only design to explore the feasibility of implementing multiphasic, community-based cancer screening at the same rural location in 2013, 2016, and 2017. The 2013 event for women screened for 2 cancers (breast and cervix), and the 2016 event for women screened for 3 cancers (breast, cervix, and thyroid). The 2017 event for men screened for 5 cancers (skin, prostate, colorectal, oropharynx, and testes). RESULTS: Totals of 473 and 401 women participated in the 2013 and 2016 events, respectively, and 301 men participated in the 2017 event. Staffing for each event varied from 33 to 44 people and relied primarily on in-country medical students and local community members. High rates (mean, 88%) of compliance with referral for follow-up testing at clinics and primary care facilities were observed after the screening events. CONCLUSION: The multiphasic, community-based approach proved feasible for both women and men and resulted in high rates of compliance with follow-up testing. This approach appears highly replicable: it was conducted multiple times across the years with different screening targets, which could be further scaled elsewhere using the same technique.

CT attenuation values and mineral distribution can be used to differentiate dogs with and without gallbladder mucoceles.

Gallbladder mucoceles are potentially fatal in dogs. Multiphase CT angiography was performed to evaluate the canine gallbladder in three conditions: no sludge, sludge occupying ≥25% of the lumen, and mucoceles. Twenty dogs with normal hepatobiliary bloodwork and no-to-minimal gallbladder sludge, 13 dogs with normal bloodwork and ≥25% sludge in the gallbladder lumen, and 18 dogs with histologically confirmed gallbladder mucoceles were enrolled in a prospective, observational diagnostic accuracy study. Three regions of interest (ROI) were stratified in the dorsal-ventral orientation and a single ROI was measured within the hepatic parenchyma. Mean attenuation and presence of mineral were recorded. Average Hounsfield units (HU) were recorded for precontrast, arterial, portovenous, and late venous phases. The overall median HU value for mucoceles was significantly higher than gallbladders without sludge and with sludge; precontrast median overall attenuation was 49.3, 35.8, and 39.7 HU, respectively (P < .000004). Mineral was seen in four (20%) dogs with no sludge, seven (56%) dogs with sludge, and nine (50%) dogs with mucoceles. Mineral in the dogs with mucoceles was located within the central aspect of the gallbladder lumen in 67% of mucoceles; this mineral distribution was not seen in any dog without a mucocele. Computed tomography can differentiate a subset of gallbladder mucoceles from dogs with and without gallbladder sludge, especially in the precontrast series. An HU value of 48.6 is 52% sensitive and 96% specific for a gallbladder mucocele. A hyperattenuating gallbladder on precontrast CT images and centrally distributed mineral can be a gallbladder mucocele.

A Multilevel Intervention With African American Churches to Enhance Adoption of Point-of-Care HIV and Diabetes Testing, 2014-2018.

We describe a multilevel intervention to enhance adoption of point-of-care HIV and diabetes testing at church health fairs in Atlanta, Georgia. Church leaders viewed a leadership video and subsequently conducted social activities that support testing. After the multilevel intervention, a third of churches hosted HIV and diabetes health fairs, and church leaders engaged in more social activities. Of 193 attendees receiving health services, 56.6% received HIV testing and 92.7% received diabetes testing. This implementation science approach could reduce HIV and diabetes disparities among African Americans.

Evaluación económica de la implantación del autoanalizador Alfred 60/AST de detección de crecimiento bacteriano con sembrador automático / Economic evaluation of the Alfred 60/AST device implantation for bacterial growth detection with automatic sewing machine

Introducción: En los laboratorios de microbiología se impone cada vez más utilizar sistemas de cribado automatizados para descartar las orinas negativas. Nuestro objetivo fue estimar el umbral presupuestario a partir del cual el autoanalizador Alfred-60/AST sería rentable para nuestro hospital. Material y métodos: Estudio de minimización de costes mediante árboles de decisión, realizado en un Hospital General. Se comparó el coste del urocultivo tradicional con el procesamiento automático mediante Alfred-60/AST. El procesamiento tradicional supone el cultivo manual de todas las orinas recibidas en agar sangre y MacConkey e identificación de todos los microorganismos aislados con el sistema Vitek-2. El autoanalizador sembraría solo las orinas positivas en un medio cromogénico que identificaría directamente los aislamientos de Escherichia coli. Resultados: Las variables con mayor impacto económico en el modelo fueron la probabilidad de obtener un cultivo positivo, la prevalencia de E. coli en los urocultivos y el coste por muestra del sembrador. El análisis de sensibilidad multivariante mostró que el modelo es sólido. El análisis de sensibilidad bivariable mostró que el modelo es sensible a la modificación de los costes, principalmente del sembrador automático. A un valor umbral de 1,40 euros por determinación, el procesamiento automático reduciría los costes anuales en 2.879 euros. Conclusión: La introducción del autoanalizador Alfred-60/AST en nuestro laboratorio a un precio de 1,40 euros por determinación reduciría la carga de trabajo en el procesamiento de orinas, ahorrando tiempo y costes

Introduction: It is becoming increasingly necessary to automatize screening of urine samples to culture at Microbiology laboratories. Our objective was to estimate the budget threshold from which the Alfred 60/AST device would be profitable for our hospital. Material and methods: Cost minimization study by decision trees, carried out in a General Hospital. The cost of traditional urine culture and urine processing using Alfred-60/AST were compared. Traditional processing involves the culture of all urine specimens received onto blood and MacConkey agar, and identification of every microorganism isolated by Vitek-2 system. The autoanalyzer would only inoculate the positive urines onto a chromogenic media, directly identifying the Escherichia coli isolates. Results: The variables with the greatest economic impact in the model were the probability of obtaining a positive culture, the prevalence of E. coli in the urine cultures and the cost per sample using Alfred-60/AST. The multivariate sensitivity analysis showed that the model was solid. The bivariate sensitivity analysis showed that the model is suceptible to cost modification, mainly of the automatic device. At a threshold value of 1.40 euros/determination, the automatic processing would decrease the annual costs in 2,879 euros. Conclusion: The introduction of the Alfred-60/AST device in our laboratory at 1.40 euros/determination would reduce urine processing workload, saving time and costs

A multifaceted model for improving the appropriateness of indications for cesarean delivery / Un modelo multifacético para mejorar la adecuación de las indicaciones de cesárea

Background: We evaluated the effectiveness of a multifaceted strategy to improve the appropriateness of the indications for cesarean delivery in 41 hospitals belonging to the Spanish National Health Service. Methods: We implemented indications for emergency and elective cesareans and analyzed their appropriateness prospectively. We provided staff with feedback and training courses and allocated the necessary resources. The results were published. A pre-post design without a control group was used. Results: The total number of deliveries in both periods was 23,711 and 29,627; of these, 5,380 and 6,371, respectively, were cesarean deliveries. The general cesarean rate decreased by 1.19 percentage points, and the overall appropriateness rate increased by 15.45% (95%CI, 13.78-17.13): 8.65% (95%CI, 6.24-11.07) for elective cesarean and 20.15% (95%CI, 17.93-22.36) for emergency cesareans. Appropriateness improved across all 5 indications for emergency cesarean, ranging from 10.87% (95%CI, 6.85-14.89) for fetal distress to 29.97% (95%CI, 24.49-35.45) for cephalopelvic disproportion. Conclusion: This strategy appears to be effective for increasing the appropriateness of the indications for cesarean delivery and reducing the complications and costs associated with the cesarean deliveries avoided

Se utilizó un diseño pre-post sin grupo control. Resultados: el número de partos en los periodos pre y post fue 23.711 y 29.627, y el de cesáreas, 5.380 y 6.371, respectivamente. El porcentaje global de cesáreas descendió 1,19, y el de adecuación global aumentó 15,45 (IC 95%: 13,78-17,13); 8,65 (IC 95%: 6,24-11,07) en el conjunto de programadas y, 20,15 (IC 95%:17,93-22,36) en el conjunto de las urgentes. La mejora en la adecuación se observó en las cinco indicaciones de cesáreas urgentes y osciló entre 10,87 (IC 95%: 6,85-14,89) en el grupo de riesgo de pérdida de bienestar fetal y 29,97 (IC 95%: 24,49-35,45) en el de desproporción pelvifetal. Conclusión: esta estrategia parece ser efectiva para aumentar la adecuación de las indicaciones de cesáreas y reducir las complicaciones y los costes asociados con las cesáreas evitadas

Overall and Multiphasic Findings of the Prostate, Lung, Colorectal and Ovarian (PLCO) Randomized Cancer Screening Trial.

BACKGROUND: Screening tests are typically evaluated for a single disease, but multiple tests for multiple diseases are performed in practice. The Prostate, Lung, Colorectal and Ovarian (PLCO) cancer screening trial assessed testing for four cancers simultaneously and can be viewed as a multiphasic cancer intervention. This paper presents overall and multiphasic findings of this trial. METHODS: The PLCO trial was a randomized multi-center trial conducted at ten screening centers in the US. Participants were 76,682 men and 78,215 women ages 55 - 74 and free of the target cancers at trial entry. Screening tests were PSA and digital rectal examination for prostate cancer, chest x-ray for lung cancer, flexible sigmoidoscopy for colorectal cancer, CA125 and transvaginal ultrasound for ovarian cancer. Outcomes and harms of screening were assessed including compliance, test results, incidence, mortality, false positives and overdiagnosis. RESULTS: Screening compliance was 82%, 72,820 (8%) of 906,064 exams were positive, the overall PPV was 4.2% and the cancer detection rate was 3.38/1000. A mortality reduction was observed only for colorectal cancer (RR 0.72, 95% CI 0.61 - 0.85) with no effect on all-cause mortality. Ninety-six percent of positive exams were falsely positive and there was a suggestion of overdiagnosis of prostate and possibly ovarian cancers. Multiphasic testing resulted in 7374 men and 2748 women experiencing multiple false positive results from multiple types of tests. CONCLUSION: Multiphasic cancer screening led to reduced mortality for one target cancer and imposed a burden on the health care system that included substantial false positives and likely overdiagnosis.

"To screen or not to screen": Comparing the health and economic benefits of early peanut introduction strategies in five countries.

BACKGROUND: Early peanut introduction (EPI) in the first year of life is associated with reduced risk of developing peanut allergy in children with either severe eczema and/or egg allergy. However, EPI recommendations differ among countries with formal guidelines. METHODS: Using simulation and Markov modeling over a 20-year horizon to attempt to explore optimal EPI strategies applied to the US population, we compared high-risk infant-specific IgE peanut screening (US/Canadian) with the Australiasian Society for Clinical Immunology and Allergy (Australia/New Zealand) (ASCIA) and the United Kingdom Department of Health (UKDOH)-published EPI approaches. RESULTS: Screening peanut skin testing of all children with early-onset eczema and/or egg allergy before in-office peanut introduction was dominated by a no screening approach, in terms of number of cases of peanut allergy prevented, quality-adjusted life years (QALY), and healthcare costs, although screening resulted in a slightly lower rate of allergic reactions to peanut per patient in high-risk children. Considering costs of peanut allergy in high-risk children, the per-patient cost of early introduction without screening over the model horizon was $6556.69 (95%CI, $6512.76-$6600.62), compared with a cost of $7576.32 (95%CI, $7531.38-$7621.26) for skin test screening prior to introduction. From a US societal perspective, screening prior to introduction cost $654 115 322 and resulted in 3208 additional peanut allergy diagnoses. Both screening and nonscreening approaches dominated deliberately delayed peanut introduction. CONCLUSIONS: A no-screening approach for EPI has superior health and economic benefits in terms of number of peanut allergy cases prevented, QALY, and total healthcare costs compared to screening and in-office peanut introduction.

Analysis of a Screening System for Diabetic Cardiovascular Autonomic Neuropathy in China.

BACKGROUND The aim of this study was to create a screening system for diabetic cardiovascular autonomic neuropathy (DCAN) in diabetic patients. MATERIAL AND METHODS A Chinese cohort of 455 diabetic participants was recruited between 2011 and 2013. Short-term heart rate variability testing was used to evaluate cardiovascular autonomic function. A simple model was developed using multiple variable regression to include only significant risk factors that were simple and easily assessed. A DCAN score was determined based on the coefficients of the multiple variable model. This score was tested on the entire cohort of 455 diabetic patients and another independent, external cohort of 115 diabetic patients. RESULTS The screening system consisted of age, body mass index, duration of diabetes mellitus, and resting heart rate, and these factors were significantly (P<0.05) associated with DCAN. Receiver operating characteristic (ROC) curve analysis was done. The areas under the ROC curve were 0.798, 0.756, and 0.729 for the total sample, validation cohort, and external set, respectively. A cutoff DCAN score of 12 out of 25 produced optimal results for sensitivity (80.36%), specificity (58.27%), and percentage of patients that needed subsequent testing (43.55%) for the validation set. CONCLUSIONS The study concludes that a simple and practical DCAN screening can be applied for early intervention to delay or prevent the disease in the Chinese population.

Out-of-Hospital screening for HIV, HBV, HCV and Syphilis in a vulnerable population, a public health challenge.

We explored rates of Hepatitis B virus (HBV), Human Immunodeficiency Virus, Hepatitis C virus and Syphilis in a vulnerable population (mostly intravenous drug users, sex workers and homeless people) and focused on factors associated with failure to return for results (FTR) and with having a false perception (FP) of Immunization against HBV. We performed a prospective multicenter observational study in nine mobile (Out-of-Hospital) areas of screening located in Paris from 1 January 2014 through 31 December 2014. A total of 341 patients were recruited. The proportion of FTR for results was 38.75%. In multivariate analysis, unemployment was significantly associated with FTR (OR = 4.29; IC = [1.12; 16.39]), as well as having been screened in the past (OR = 4.32, IC = [1.70; 10.97]); 18.03% of patients had a FP of an Immunization against HBV. In multivariate analysis, having one's own place of residence protected against FP (OR = 0.33, [0.12; 0.95]), while being screened in the past enhanced the risk of FP (OR = 3.28, IC = [1.06; 10.11]). The rate of FTR is a problem and use of currently available technologies, such as phone texting, might be a partial solution in conjunction with rapid tests for diagnosis. In addition, more information and comprehension of the results should be provided together with specific anti-HBV vaccination campaigns targeting these specific populations.

Obesity, diabetes, serum glucose, and risk of primary liver cancer by birth cohort, race/ethnicity, and sex: Multiphasic health checkup study.

OBJECTIVE: Obesity and diabetes have been associated with liver cancer. However, recent US-based studies have suggested a lack of association between obesity and liver cancer among blacks and women. METHODS: We conducted a nested case-control study within the Multiphasic Health Checkup (MHC) cohort of Kaiser Permanente Northern California (KPNC) members. Liver cancer was diagnosed using the KPNC Cancer Registry. Detailed self-administered questionnaires and a standardized examination that included measurement of height and weight and a 1-h glucose tolerance test were completed prior to diagnosis of liver cancer for cases (n=450) and matched controls (4489). Height and weight were utilized to calculate BMI (kg/m(2)) as a measure of adiposity: underweight (15-≤8.5kg/m(2)), normal weight (18.5-≤25kg/m(2)), overweight (25-≤30kg/m(2)), and obese (≥30kg/m(2)). Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CI) for the association between BMI, diabetes, and serum glucose with subsequent incidence of liver cancer, in models that were stratified by birth cohort, race/ethnicity, and sex. RESULTS: Compared to normal weight individuals, obese individuals had a 2.4-fold increased risk of liver cancer (OR=2.38, 95% CI: 1.68-3.36), and overweight individuals had a 32% increased risk (OR=1.32, 95% CI: 1.03-1.70). This association did not differ when stratified by birth cohort, race/ethnicity, or sex (pint>0.05). Among blacks and women, obesity was associated with at least a 2-fold increased risk of liver cancer (OR=2.29, 95% CI: 1.22-4.28 and OR=2.00, 95% CI: 1.14-3.52, respectively). More moderate increased odds ratios were noted for diabetes (OR=1.28, 95% CI: 0.65-2.54) and serum glucose ≥200mg/dL (OR=1.63, 95% CI: 0.48-5.55), although the results did not attain statistical significance. CONCLUSION: In summary, our finding of a positive association between obesity and liver cancer suggests that a higher BMI may increase the risk of liver cancer in the US, for both sexes and all race/ethnicities.

Hepatitis C Screening Rate Among Underserved Adults With Serious Mental Illness Receiving Care in California Community Mental Health Centers.

Although HCV is more prevalent among people with severe mental illness (SMI; e.g., schizophrenia, bipolar disorder) than in the general population (17% vs 1%), no large previous studies have examined HCV screening in this population. In this cross-sectional study, we examined administrative data for 57 170 California Medicaid enrollees with SMI to identify prevalence and predictors of HCV screening from October 2010 through September 2011. Only 4.7% (2674 of 57 170) received HCV screening, with strongest predictors being nonpsychiatric health care utilization and comorbid substance abuse.

Poor Collateral Circulation Assessed by Multiphase Computed Tomographic Angiography Predicts Malignant Middle Cerebral Artery Evolution After Reperfusion Therapies.

BACKGROUND AND PURPOSE: Collateral circulation (CC) has been associated with recanalization, infarct volume, and clinical outcome in patients undergoing acute reperfusion therapies. However, its relationship with the development to malignant middle cerebral artery infarction (mMCAi) has not been evaluated. Our aim was to determine the impact of CC using multiphase computed tomographic angiography (during the acute stroke phase in the prediction of mMCAi. METHODS: Patients with consecutive acute stroke with <4.5 hours who were evaluated for reperfusion therapies and presented with an M1-MCA or terminal internal carotid artery occlusion by CTA were included. CC was evaluated on 6 grades by multiphase CTA according to the University of Calgary CC Scale; CC status was defined as poor (grades, 0-3) or good (grades, 4-5). The mMCAi was defined according to clinical and radiological criteria. Recanalization was assessed with transcranial Doppler at 24 hours and final Thrombolysis in Brain Ischemia score≥2b in patients undergoing endovascular reperfusion treatment. RESULTS: Eighty-two patients were included. Mean age was 65.1±13.83 years, median baseline National Institutes of Health Stroke Scale score was 18 (interquartile range, 13-20), and 67.9% M1 and 32.1% terminal internal carotid artery occlusions. Fifty-three patients received endovascular reperfusion treatment. Fifteen patients developed mMCAi. In the univariate analysis, patients with mMCAi had lower CC scores (2.29 versus 3.71; P=0.001). Endovascular reperfusion treatment was associated with lower rate of mMCAi development than only intravenous reperfusion treatment (9.4% versus 29.6%; P=0.028). Patients with poor CC had higher risk of developing mMCAi (13% versus 2%; P=0.001). On the multivariate analysis adjusted by age, vessel occlusion, baseline National Institutes of Health Stroke Scale, and recanalization, the presence of poor CC by multiphase CTA was the only independent predictor of mMCAi (P=0.048; odds ratio, 9.72; 95% confidence interval, 1.387-92.53). CONCLUSIONS: CC assessment by multiphase CTA independently predicts malignant MCA infarction progression. In patients with persistent occlusion after reperfusion therapies, the presence of poor CC may improve the early mMCAi detection and management.
