Glycemic control, depression, diabetes distress among adolescents with type 2 diabetes: effects of sex, race, insurance, and obesity.

AIMS: To determine (1) differences in depression and distress scores between adolescents with type 1 (T1D) and type 2 diabetes (T2D), (2) how socioeconomic factors, obesity, race, and treatment regimen affect depression and diabetes distress in adolescent T2D, (3) the relationships between depression and diabetes distress scores in adolescents with T2D, and (4) how depression and diabetes distress scores relate to current and future glycemic control in adolescents with T2D. BACKGROUND: Diabetes distress is a negative emotional reaction to diabetes complications, self-management demands, unresponsive providers, poor interpersonal relationships, and to diabetes itself. It is frequently mistaken for depression and the two are interrelated. Increases in both predict poor glycemic control in adolescents with T1D. METHOD: Depression (PHQ-9) and diabetes distress (PAID-T) scores from self-administered tests were studied in 364 patients with diabetes between the ages of 13-17. Kruskal-Wallis test was used to assess differences between types of diabetes, sexes, races, and insurance status. Spearman correlations, and robust rank order multivariable regression analysis were used to assess relationships. Medical records were reviewed for follow-up hemoglobin A1c (HbA1c) levels over 3 years. RESULTS: HbA1c was significantly lower in females with T2D than with T1D (p = 0.019) but not in males. It, also, did not differ between females and males with T2D. Median PHQ-9 score in females with T2D was significantly greater than in females with T1D (p = 0.007) but did not differ between females and males with T2D. PHQ-9 scores did not differ between males with T2D and T1D. PAID-T scores, however, were higher in males with T2D than in males with T1D but did not differ between females. PHQ-9 scores and PAID-T scores were significantly related in T2D (rs = 0.65, p < 0.001). Neither was related to HbA1c in T2D. CONCLUSIONS: As in adolescents with T1D, depression and diabetes distress screening scores are closely related in adolescent T2D. However, unlike T1D, they are not related to glycemic control in T2D. Depression and diabetes distress may be more closely related to weight and lifestyle concerns.

Glycemic control, depression, diabetes distress among adolescents with type 1 diabetes: effects of sex, race, insurance, and obesity.

AIMS: To determine whether diabetes distress or depression screening better predict increased hemoglobin A1c (HbA1c) and to assess interactions with age, sex, race, obesity, and insurance status. BACKGROUND: Diabetes distress is a negative emotional reaction to diabetes, diabetes complications, self-management demands, unresponsive providers, and/or poor interpersonal relationships. Guidelines recommend annual depression screening, however diabetes distress may be mistaken for depression. METHOD: Depression (PHQ-9) and diabetes distress (PAID-T) scores from self-administered tests were studied in 313 patients with type 1 diabetes (T1D) between the ages of 13-17. Spearman correlations and robust rank order multivariable regression analysis were used to assess relationships to age, duration, HbA1c. Kruskal-Wallis test was used to assess differences between sexes, races, and insurance status. Receiver operator curves (ROC) were constructed to see whether PAID-T or PHQ-9 scores more closely predicted HbA1c greater than 9%. RESULTS: HbA1c was more strongly correlated with PAID-T (rs = 0.37, p < 0.01), than PHQ-9 (rs = 0.27, p < 0.01) scores. Area under ROC curve for poor HbA1c was 0.75 for PAID and 0.64 for PHQ-9. PAID-T and PHQ-9 scores were increased in females and subjects with public insurance and both were significantly related to HbA1c even when accounting for age, sex, race obesity, and insurance status. PHQ-9 and PAID-T scores correlated with BMI-Z scores in Blacks, but not Whites. CONCLUSIONS: Both depression and diabetes distress are associated with increased HbA1c in adolescents with T1D, though distress is more so. Diabetes distress and depression should be routinely assessed in T1D adolescents, particularly those with public insurance.

How European primary care practitioners think the timeliness of cancer diagnosis can be improved: a thematic analysis.

BACKGROUND: National European cancer survival rates vary widely. Prolonged diagnostic intervals are thought to be a key factor in explaining these variations. Primary care practitioners (PCPs) frequently play a crucial role during initial cancer diagnosis; their knowledge could be used to improve the planning of more effective approaches to earlier cancer diagnosis. OBJECTIVES: This study sought the views of PCPs from across Europe on how they thought the timeliness of cancer diagnosis could be improved. DESIGN: In an online survey, a final open-ended question asked PCPs how they thought the speed of diagnosis of cancer in primary care could be improved. Thematic analysis was used to analyse the data. SETTING: A primary care study, with participating centres in 20 European countries. PARTICIPANTS: A total of 1352 PCPs answered the final survey question, with a median of 48 per country. RESULTS: The main themes identified were: patient-related factors, including health education; care provider-related factors, including continuing medical education; improving communication and interprofessional partnership, particularly between primary and secondary care; factors relating to health system organisation and policies, including improving access to healthcare; easier primary care access to diagnostic tests; and use of information technology. Re-allocation of funding to support timely diagnosis was seen as an issue affecting all of these. CONCLUSIONS: To achieve more timely cancer diagnosis, health systems need to facilitate earlier patient presentation through education and better access to care, have well-educated clinicians with good access to investigations and better information technology, and adequate primary care cancer diagnostic pathway funding.

Identifying important health system factors that influence primary care practitioners' referrals for cancer suspicion: a European cross-sectional survey.

OBJECTIVES: Cancer survival and stage of disease at diagnosis and treatment vary widely across Europe. These differences may be partly due to variations in access to investigations and specialists. However, evidence to explain how different national health systems influence primary care practitioners' (PCPs') referral decisions is lacking.This study analyses health system factors potentially influencing PCPs' referral decision-making when consulting with patients who may have cancer, and how these vary between European countries. DESIGN: Based on a content-validity consensus, a list of 45 items relating to a PCP's decisions to refer patients with potential cancer symptoms for further investigation was reduced to 20 items. An online questionnaire with the 20 items was answered by PCPs on a five-point Likert scale, indicating how much each item affected their own decision-making in patients that could have cancer. An exploratory factor analysis identified the factors underlying PCPs' referral decision-making. SETTING: A primary care study; 25 participating centres in 20 European countries. PARTICIPANTS: 1830 PCPs completed the survey. The median response rate for participating centres was 20.7%. OUTCOME MEASURES: The factors derived from items related to PCPs' referral decision-making. Mean factor scores were produced for each country, allowing comparisons. RESULTS: Factor analysis identified five underlying factors: PCPs' ability to refer; degree of direct patient access to secondary care; PCPs' perceptions of being under pressure; expectations of PCPs' role; and extent to which PCPs believe that quality comes before cost in their health systems. These accounted for 47.4% of the observed variance between individual responses. CONCLUSIONS: Five healthcare system factors influencing PCPs' referral decision-making in 20 European countries were identified. The factors varied considerably between European countries. Knowledge of these factors could assist development of health service policies to produce better cancer outcomes, and inform future research to compare national cancer diagnostic pathways and outcomes.

The Recent Pathology Residency Graduate Job Search Experience: A Synthesis of 5 Years of College of American Pathologists Job Market Surveys.

CONTEXT: - Pathology residents and fellows tailor their training and job search strategies to an actively evolving specialty in the setting of scientific and technical advances and simultaneous changes in health care economics. OBJECTIVE: - To assess the experience and outcome of the job search process of pathologists searching for their first non-fellowship position. DESIGN: - The College of American Pathologists (CAP) Graduate Medical Education Committee has during the past 5 years sent an annual job search survey each June to CAP junior members and fellows in practice 3 years or less who have actively searched for a non-fellowship position. RESULTS: - Job market indicators including job interviews, job offers, positions accepted, and job satisfaction have remained stable during the 5 years of the survey. Most survey respondents who had applied for at least 1 position had accepted a position at the time of the survey, and most applicants who had accepted a position were satisfied or very satisfied. However, most attested that finding a non-fellowship position was difficult. Despite a perceived push toward subspecialization in surgical pathology, the reported number of fellowships completed was stable. Respondent demographics were not associated with job search success with 1 significant exception: international medical school graduate respondents reported greater perceived difficulty in finding a position, and indeed, fewer reported having accepted a position. CONCLUSIONS: - Pathology residents and fellows seeking their first position have faced a relatively stable job market during the last 5 years, with most accepting positions with which they were satisfied.

Assessment and Management of Professionalism Issues in Pathology Residency Training: Results From Surveys and a Workshop by the Graduate Medical Education Committee of the College of American Pathologists.

Professionalism issues are common in residency training and can be very difficult to recognize and manage. Almost one-third of the milestones for pathology recently instituted by the Accreditation Council for Graduate Medical Education encompass aspects of professionalism. Program directors are often unsure of how and when to remediate residents for unprofessional behavior. We used a case-based educational approach in a workshop setting to assist program directors in the management of unprofessional behavior in residents. Eight case scenarios highlighting various aspects of unprofessional behavior by pathology residents were developed and presented in an open workshop forum at the annual pathology program director's meeting. Prior to the workshop, 2 surveys were conducted: (1) to collect data on program directors' experience with identifying, assessing, and managing unprofessional behavior in their residents and (2) to get feedback from workshop registrants on how they would manage each of the 8 case scenarios. A wide range of unprofessional behaviors have been observed by pathology program directors. Although there is occasionally general agreement on how to manage specific behaviors, there remains wide variation in how to manage many of the presented unprofessional behaviors. Remediation for unprofessional behavior in pathology residents remains a difficult and challenging process. Additional education and research in this area are warranted.

Influencing preferences for different types of causal explanation of complex events.

OBJECTIVE: We examined preferences for different forms of causal explanations for indeterminate situations. Background: Klein and Hoffman distinguished several forms of causal explanations for indeterminate, complex situations: single-cause explanations, lists of causes, and explanations that interrelate several causes. What governs our preferences for single-cause (simple) versus multiple- cause (complex) explanations? METHOD: In three experiments, we examined the effect of target audience, explanatory context, participant nationality, and explanation type. All participants were college students. Participants were given two scenarios, one regarding the U.S. economic collapse in 2007 to 2008 and the other about the sudden success of the U.S. military in Iraq in 2007. The participants were asked to assess various types of causal explanations for each of the scenarios, with reference to one or more purposes or audience for the explanations. RESULTS: Participants preferred simple explanations for presentation to less sophisticated audiences. Malaysian students of Chinese ethnicity preferred complex explanations more than did American students. The form of presentation made a difference: Participants preferred complex to simple explanations when given a chance to compare the two, but the preference for simple explanations increased when there was no chance for compari- son, and the difference between Americans and Malaysians disappeared. CONCLUSIONS: Preferences for explanation forms can vary with the context and with the audience, and they depend on the nature of the alternatives that are provided. APPLICATION: Guidance for decision-aiding technology and training systems that provide explanations need to involve consideration of the form and depth of the accounts provided as well as the intended audience.

Hospitalized but not admitted: characteristics of patients with "observation status" at an academic medical center.

IMPORTANCE: The Centers for Medicare & Medicaid Services (CMS) defines observation status for hospitalized patients as a "well-defined set of specific, clinically appropriate services," usually lasting less than 24 hours, and that in "only rare and exceptional cases" should last more than 48 hours. Although an increasing proportion of observation care occurs on hospital wards, studies of patients with observation status have focused on the efficiency of dedicated units. OBJECTIVE: To describe inpatient and observation care. DESIGN AND SETTING: Descriptive study of all inpatient and observation stays between July 1, 2010, and December 31, 2011, at the University of Wisconsin Hospital and Clinics, a 566-bed tertiary academic medical center. PARTICIPANTS: All patients with observation or inpatient stays during the study period. MAIN OUTCOMES AND MEASURES: Patient demographics, length of stay, difference between cost and reimbursement per stay, and percentage of patients discharged to skilled nursing facilities. RESULTS: Of 43,853 stays, 4578 (10.4%) were for observation, with 1141 distinct diagnosis codes. Mean observation length of stay was 33.3 hours, with 44.4% of stay durations less than 24 hours and 16.5% more than 48 hours. Observation care had a negative margin per stay (-$331); the inpatient margin per stay was positive (+$2163). Adult general medicine patients accounted for 2404 (52.5%) of all observation stays; 25.4% of the 9453 adult general medicine stays were for observation. The mean length of stay for general medicine observation patients was 41.1 hours, with 32.6% of stay durations less than 24 hours and 26.4% more than 48 hours. Compared with observation patients on other clinical services, adult general medicine had the highest percentage of patients older than 65 years (40.9%), highest percentage female patients (57.9%), highest percentage of patients discharged to skilled nursing facilities (11.6%), and the most negative margin per stay (-$1378). CONCLUSIONS AND RELEVANCE: In an academic medical center, observation status for hospitalized patients differed markedly from the CMS definition. Patients had a wide variety of diagnoses; lengths of stay were typically more than 24 hours and often more than 48 hours. The hospital lost money, primarily because reimbursement for general medicine patients was inadequate to cover the costs. It is uncertain what role, if any, observation status for hospitalized patients should have in the era of health care reform.

Factors associated with failure to follow-up at a medical clinic after an ED visit.

BACKGROUND: Although emergency department (ED) discharge is often based on the presumption of continued care, the reported compliance rate with follow-up appointments is low. STUDY OBJECTIVES: The objectives of this study are to identify factors associated with missed follow-up appointments from the ED and to assess the ability of clinicians to predict which patients will follow-up. METHODS: Patients without insurance or an outpatient primary care provider (PCP) were given a follow-up clinic appointment before discharge. Information identifying potential follow-up barriers was collected, and the physician's perception of the likelihood of follow-up was recorded. Patients who missed their appointment were contacted via telephone and were offered a questionnaire and a rescheduled clinic appointment. RESULTS: A total of 125 patients with no PCP were enrolled. Sixty (48%; 95% confidence interval, 39-57) kept their scheduled appointment. Sex, distance from clinic, availability of transportation, or time since last nonemergent physician visit was associated with attendance to the follow-up visit. Clinicians were unable to predict which patients would follow-up. Contact by telephone was made in 48 (74%) of patients who failed to follow-up. Of the 14 patients willing to reschedule, none returned for follow-up. CONCLUSION: Among ED patients who lack a PCP and are given a clinic appointment from the ED, less than half keep the appointment. Moreover, clinicians are unable to predict which patients will follow up. This study highlights the difficulty in maintaining continuity of care in populations who are self-pay or have Medicaid and lack regular providers. This may have implications on discharge planning from the ED.

Pathology subspecialty fellowship application reform, 2007-2010.

The specialty of pathology and laboratory medicine has entered a phase in which the 4-year sequence of residency training is almost universally followed by 1 or more years of subspecialty fellowship training. Such training may occur in an American Board of Pathology-recognized subspecialty or any number of "subspecialty fellowships" that do not lead to subspecialty board certification. Unlike the application process for first-year pathology residency, which is run through the National Resident Matching Program, applications for subspecialty pathology fellowships have no consistent coordination. Responding to widespread dissatisfaction voiced in 2007 by national pathology resident organizations, the Association of Pathology Chairs began evaluation and potential intervention in the fellowship application process. After 3 years of effort, the Council of the Association of Pathology Chairs has recommended implementation of a pathology subspecialty fellowship matching program starting in the 2011-2012 recruiting year for applicants matriculating in fellowship programs in July 2013. We report on the data that informed this decision and discuss the pros and cons that are so keenly felt by the stakeholders in this as-yet-incomplete reform process.

Pathology subspecialty fellowship application reform 2007 to 2010.

The specialty of Pathology and Laboratory Medicine has entered into a phase when the 4-year sequence of Anatomic Pathology and/or Clinical Pathology Residency Training is almost universally followed by 1 or more years of Subspecialty Fellowship Training. Such training may occur in one of the American Board of Pathology-recognized subspecialties or any number of "subspecialty fellowships" that, although not leading to subspecialty board certification, may nevertheless fall under the oversight of the local institutional Graduate Medical Education Committee and the Accreditation Council for Graduate Medical Education Review Committee for Pathology. Unlike the application process for first-year Pathology Residency, which is run through the National Resident Matching Program, applications for Subspecialty Pathology Fellowships are not coordinated by any consistent schedule. Competition for Subspecialty Pathology Fellowships has consistently resulted in undesirable drift of the fellowship application process to dates that are unacceptably early for many fellowship applicants. Responding to widespread dissatisfaction voiced by national pathology resident organizations, in 2007, the Association of Pathology Chairs began evaluation and potential intervention in the fellowship application process. Three years of intermittently intense discussion, surveys, and market analysis, have led the Council of the Association of Pathology Chairs to recommend implementation of a Pathology Subspecialty Fellowship Matching program starting in the 2011 to 2012 recruiting year, for those Applicants matriculating in fellowship programs July 2013. We report on the data that informed this decision and discuss the pros and cons that are so keenly felt by the stakeholders in this as-yet-incomplete reform process.

Long-term adherence to antihypertensive therapy: a survey in four primary care clinics.

BACKGROUND: Many hypertensive patients have suboptimal control of their blood pressure. One of the most common causes is poor adherence with treatment. AIM: To identify factors associated with poorer adherence to antihypertensive treatment. METHODS: The study was conducted in four urban clinics of Clalit Health Services (Israel's largest Health management organization): 3799 patients aged > 20 years with hypertension in whom a new antihypertensive medicine was started in a 3-year period were included. Data included: age; gender; chronic diseases; type of antihypertensive medicine; and adherence with treatment. Reasons for non-adherence had been evaluated in a random sample of 453 of the medical records. RESULTS: Of the patients, 2234/3799 (58.8%) stopped >or= 1 medicine. Lower adherence was associated with female gender, new immigration, ischemic heart disease and being a non-diabetic. Adherence was related to the type of medicine. The highest rates of adherence were found with the use of angiotensin receptor blockers (59.1%) and selective beta-blockers (59%), and the lowest with non-selective beta-blockers (30.1%). There was no documentation of the reason to medicine cessation in 183/453 (40.4%) of the medical records. In 20.1% of cessations, the physician continued to prescribe the drug, despite the fact that the patient had stopped purchasing it. Common reasons for treatment cessation were side effects (15%) and lack of blood pressure control (5.5%). CONCLUSIONS: Adherence with antihypertensive treatment declines with time and is associated with the type of medicine, and sociodemographic and clinical backgrounds. Family physicians must increase their documentation and awareness to medicine adherence.

Can screening for optic nerve gliomas in patients with neurofibromatosis type I be performed with visual-evoked potential testing?

BACKGROUND: Screening for optic nerve gliomas (ONGs) in children with neurofibromatosis type 1 (NF1) is problematic. Visual acuity (VA) can be unreliable in children. Magnetic resonance imaging is the most sensitive test for ONG, but it is expensive. This study was designed to determine whether visual-evoked potential testing (VEP) is a sensitive and cost-effective screening test for ONG in NF1 in children. METHODS: We undertook a retrospective review of patients with NF1 at a tertiary care eye center that were born between 1983 and 2003. VA was considered abnormal if 20/40 or worse or more than 2 lines difference between eyes. VEP was abnormal if the P100 was >108 ms (ms) or the interocular difference was greater than 5.0 ms. RESULTS: Of 297 patients found with NF1, 144 were children and 30 had VEP and MRI. Of those, 14 had ONG and 16 did not. The average P100 of the VEP was 110.5 ms in patients with ONG compared with 103.1 ms (p = 0.004) in those without ONG. VEP was 86% sensitive and 75% specific in detecting ONG. VA was 50% sensitive and 50% specific. Six patients with ONG had normal vision and abnormal VEP. Two subjects had initial abnormal VEP but normal MRI and showed ONG on follow-up imaging. One subject with ONG had a normal VEP initially but subsequent VEP was abnormal. CONCLUSION: Using serial VEPs, the sensitivity is 93%. Cost of VEP and MRI is $150 and $1750, respectively. VEP is a sensitive and cost-effective screening test for ONG in NF1. VEP may assist in earlier diagnoses of ONG, especially in children with equivocal or difficult ophthalmic examinations.

Advantages of multi-color fluorescent proteins for whole-body and in vivo cellular imaging.

The revolution of in vivo cancer biology enabled by fluorescent proteins is described. The high extinction coefficients, quantum yields, and unique spectral properties of fluorescent proteins have been taken advantage of in order to visualize, in real time, the important aspects of cancer in living animals, including tumor cell trafficking, invasion, metastasis, and angiogenesis. Fluorescent proteins enable whole-body imaging of tumors on internal organs. These multicolored proteins have allowed the color-coding of cancer cells growing in vivo with distinction of different cell types, including host from tumor, with single-cell resolution.

BD Biosciences contributions in CD4 counting and immune status for HIV/AIDS.

BD Biosciences is a leader in the use of flow cytometry for determining immune system status and for counting CD4 cells in patients with human immunodeficiency virus (HIV) infection. The company has gained this position through many years of basic research and product development in immunology and cell biology, dye chemistry, immunoassays, instrumentation, and software. Some of the highlights of these developments and their historical perspective are described in this review.

Near-infrared dyes for six-color immunophenotyping by laser scanning cytometry.

BACKGROUND: To adequately analyze the complexity of the immune system and reduce the required sample volume for immunophenotyping in general, more measurable colors for the discrimination of leukocyte subsets are necessary. Immunophenotyping by the laser scanning cytometer (LSC), a slide-based cytometric technology, combines cell detection based on multiple colors with their subsequent visualization without the need for physical cell sorting. In the present study, the filter setting of the LSC was adapted for the measurement of the far-red emitting dye cyanine 7 (Cy7), thereby increasing the number of measurable commercially available fluorochromes. METHODS: The optical filters of the LSC were replaced-photomultiplier (PMT) 3/allophycocyanin (APC): 740-nm dichroic long pass, and 670-/55-nm bandpass; PMT 4/Cy7: 810-/90-nm bandpass. Peripheral blood leukocytes were stained directly by fluorochrome-labeled antibodies or by indirect staining. The tandem dyes of Cy7 (phycoerythrin [PE]-Cy7, APC-Cy7) and the fluorochromes fluorescein isothiocyanate (FITC), PE, PE-Cy5, and APC were tested alone and in different combinations. RESULTS: With the new filter combination and tandem fluorochromes, Cy7 was measurable at 488-nm (argon laser) or 633-nm (helium-neon laser) excitation. Resolution was in the range of FITC for PE-Cy7 but approximately 30% lower for APC-Cy7; spillover into the respective donor fluorochrome channel for both tandem dyes was prominent. A six-color panel for leukocyte subtyping was designed. CONCLUSIONS: With this adaptation, it is possible to measure the tandem conjugates PE-Cy7 and APC-Cy7. This new setup opens the way for six-color immunophenotyping by LSC.
