Declaration of Helsinki-the world's document of conscience and responsibility.

Abstract: Iwant to commend to you the guest editorial by Dr Ramin Parsa-Parsi and his colleagues on the 2013 revision of the World Medical Association’s (WMA’s) Declaration of Helsinki. This seminal document has been revised over the years, in keeping with the increasing sophistication of the field of bioethics as well as the expanding responsibilities for global health and international medicine. Dr. Parsa-Parsi headed the revision committee of the WMA for this latest revision, an extremely important position and task. We have just welcomed him as a new member of the international editorial board of the Southern Medical Journal, a great honor for our publication. The authors of this editorial identify the Declaration of Helsinki as a ‘‘living document,’’ one which was born in 1947, a time of great challenge for the medical profession and its integrity in patient care and human research. Following World War II, a number of Nazi physicians were placed on trialVa total of 12 trialsVin Nuremberg, Germany for war crimes and atrocities, including human experimentation and genocide, committed against human beings. These were known collectively as the Nuremberg doctors’ trials, and included Adolf Hitler’s personal physician and the chief physicians of several of the Nazi concentration camps. As the conduct of unethical experimentation on people by Nazi physicians became known globally through testimony and evidence, there was a realization of certainty within the international medical community that clear and concrete regulations for the conduct of legitimate human research must be developed and adhered to. Also clear was the realization that Nazi physicians had philosophically and functionally uncoupled the important dyadic principles of beneficence and nonmaleficence, effectively discarding or ignoring the enduringHippocratic principle of ‘‘first, do no harm.’’ While the Nuremberg trials were progressing, the Nuremberg Code was developedVa list of 10 guiding principles for the proper and ethical conduct of human research. Although never translated into law, the Code became the philosophical foundation for the more globally recognized regulations for human research compiled in the original 1947 Declaration of Helsinki. In fact, it is my understanding that the WMA was born as a result of the global medical profession’s recognition that a powerful voice for ethics and integrity needed to be heard. In addition, the WMA developed the Declaration of Geneva, which has become a widely used and highly regarded alternative to the Hippocratic Oath for delineating the obligations and duties of a physician. Every healthcare provider should be familiar with the Declaration of Geneva and the Declaration of Helsinki, as well as the fundamentals of human research obligations defined in the original Nuremberg Code. The principles codified in the Declaration of Helsinki became the basis for the regulations defining human subject research subsequently adopted in the United States. It is at once fascinating and appropriate that this document has been revised through the decades to reflect the modern practices of medicine and medical research, which confirms the importance of its principles to the advancement of science and the protection of human research subjects. We thank Dr Parsa-Parsi and his colleagues for their dedicated effort in this regard and for helping us better understand this vitally important document and its enduring application to modern medicine.

Where are the rest of us? Improving representation of minority faculty in academic medicine.

Abstract: Objectives Low numbers of underrepresented minority faculty members in academic medicine (black, Hispanic, Asian/Pacific Islander, Native American/Alaskan) continue to be a concern for medical schools because there is higher attrition and talent loss among this group. Although much has been written on this topic, there has not been a systematic review of the indexed literature published. Methods We searched MEDLINE, Web of Knowledge, ProQuest, and Google Scholar for articles relating to minority faculty and identified relevant articles. We then graded the evidence using the Strength of Recommendation Taxonomy. The same criteria were applied to extract evidence-based observations of challenges faced by minority faculty and provide recommendations. Results Of the 548 studies identified and reviewed, 15 met inclusion criteria for this literature review. Of the 15, 9 were cross-sectional studies and 6 were analyses of existing Association of American Medical Colleges workforce data. The cross-sectional studies documented perceived bias in the recruitment of faculty, quantified the lack of minority mentors, and revealed that black and Hispanic faculty members are more prevalent in states with higher minority populations. Studies using the Association of American Medical College workforce data also documented evidence of promotion bias, the lack of diversity in academic plastic surgery, and the lack of minority researchers funded by the National Cancer Institute. Conclusions This systematic review provides evidence that racism, promotion disparities, funding disparities, lack of mentorship, and diversity pressures exist and affect minority faculty in academic medicine. Based on these observed challenges, this review also provides specific recommendations that could improve representation of minority faculty members in academic medicine. These recommendations include implementing proven pipeline programs to increase the number of minority medical students, a systemwide adoption of proven culture change initiatives, reexamination of assignments to ensure equitable time distribution, and a reduction of medical school debt.

Project BOOST implementation: lessons learned.

Abstract: Objectives Enhancing care coordination and reducing hospital readmissions have been a focus of multiple quality improvement (QI) initiatives. Project BOOST (Better Outcomes by Optimizing Safe Transitions) aims to enhance the discharge transition from hospital to home. Previous research indicates that QI initiatives originating externally often face difficulties gaining momentum or effecting lasting change in a hospital. We performed a qualitative evaluation of Project BOOST implementation by examining the successes and failures experienced by six pilot sites. We also evaluated the unique physician mentoring component of this program. Finally, we examined the impact of intensification of the physician mentoring model on adoption of BOOST interventions in two later Illinois cohorts (27 hospitals). Methods Qualitative analysis of six pilot hospitals used a process of methodological triangulation and analysis of the BOOST enrollment applications, the listserv, and content from telephone interviews. Evaluation of BOOST implementation at Illinois hospitals occurred via mid-year and year-end surveys. Results The identified common barriers included inadequate understanding of the current discharge process, insufficient administrative support, lack of protected time or dedicated resources, and lack of frontline staff buy-in. Facilitators of implementation included the mentor, a small beginning, teamwork, and proactive engagement of the patient. Notably, hospitals viewed their mentors as essential facilitators of change. Sites consistently commented that the individualized mentoring was extremely helpful and provided significant accountability and stimulated creativity. In the Illinois cohorts, the improved mentoring model showed more complete implementation of BOOST interventions. Conclusions The implementation of Project BOOST was well received by hospitals, although sites faced substantial barriers consistent with other QI research reports. The unique mentorship element of Project BOOST proved extremely valuable in helping sites overcome their distinctive challenges and identify facilitators for success. The findings from this qualitative study should contribute to future BOOST implementation success and others' efforts to optimize hospital discharge transitions.

Fixed drug eruptions: presentation, diagnosis, and management.

Abstract: Fixed drug eruption (FDE) is a well-defined, circular, hyperpigmenting plaque that recurs as one or a few lesions always in fixed locations upon ingestion of a drug. FDE commonly occurs on the genitals, lips, trunk, and hands. Although the lesions are distinctive, the diagnosis of FDE often is missed because it shares none of the characteristics of more common morbilliform drug rashes. The diagnosis can be confirmed by histopathologic examination of a small punch biopsy specimen. Drug avoidance is the mainstay of treatment, and antihistamines can reduce associated pruritus. Raising awareness of this condition will increase the likelihood of prompt diagnosis leading to resolution within days to weeks after the offending drug is discontinued.

Hyperuricemia, gout, and related comorbidities: cause and effect on a two-way street.

Abstract: The prevalence of gout and hyperuricemia has increased dramatically during the last several decades, to the point that gout is the most common inflammatory arthritis in the United States, affecting approximately 8 million Americans. Patients with gout frequently have multiple comorbidities, including hypertension, chronic kidney disease, cardiovascular disease, obesity, diabetes, and hyperlipidemia, all of which have significant adverse impact on public health. In some cases (eg, chronic kidney disease) it is clear that the presence of the comorbidity contributes to the progression of hyperuricemia and/or gout. Conversely, the question of whether gout/hyperuricemia themselves contribute to the pathogenesis of gout comorbidities is an area of intensifying investigation. In vitro and animal models, large epidemiologic studies, and small clinical trials suggest that gout and/or hyperuricemia may contribute to hypertension, chronic kidney disease, and cardiovascular disease. More limited hypothesis-generating studies suggest a potential role for diabetes and obesity. Given that available drugs can lower serum urate levels and manage gout, it would be important to know whether not only gout and/or hyperuricemia can contribute to comorbidities but also better gout/hyperuricemic control can ameliorate some or all of these related conditions. We review the clinical associations between gout and its common comorbid conditions and the evidence supporting a causal relation between them. The evidence that gout and hyperuricemia contribute to the pathogenesis of their comorbidities creates greater urgency for appropriate gout management.

Acromioclavicular osteoarthritis: a common cause of shoulder pain.

Abstract: Osteoarthritis of the acromioclavicular joint is a frequent cause of shoulder pain and can result in significant debilitation. It is the most common disorder of the acromioclavicular joint and may arise from a number of pathologic processes, including primary (degenerative), posttraumatic, inflammatory, and septic arthritis. Patients often present with nonspecific complaints of pain located in the neck, shoulder, and/or arm, further complicating the clinical picture. A thorough understanding of the pertinent anatomy, disease process, patient history, and physical examination is crucial to making the correct diagnosis and formulating a treatment plan. Initial nonoperative management is aimed at relieving pain and restoring function. Typical treatments include anti-inflammatory medications, physical therapy, and injections. Patients who continue to exhibit symptoms after appropriate nonsurgical treatment may be candidates for operative resection of the distal clavicle through either open or arthroscopic techniques.

Serum biomarkers for traumatic brain injury.

Abstract: There is a lack of reliable serum biomarkers for routine use in the diagnostic workup of people with traumatic brain injury. Multiple biomediators and biomarkers have been described in the pertinent lit- erature in recent years; however, only a few candidate molecules have been associated with high sensitivity and high specificity for risk stratification and outcome prediction after traumatic brain injury. This review was designed to provide an overview of the state of the art re- garding established serum biomarkers in the field and to outline future directions of investigation.

Graves Orbitopathy: Update on Diagnosis and Therapy

Abstract: Graves orbitopathy (GO) is an autoimmune disorder representing the most frequent extrathyroidal manifestation of Graves disease. It is rare, with an age-adjusted incidence of approximately 16.0 cases per 100,000 population per year in women and 2.9 cases per 100,000 population per year in men. GO is an inflammatory process characterized by edema and inflammation of the extraocular muscles and an increase in orbital connective tissue and fat. Despite recent progress in the understanding of its pathogenesis, GO often remains a major diagnostic and therapeutic challenge. It has become increasingly important to classify patients into categories based on disease activity at initial presentation. A Hertel exophthalmometer measurement of >2 mm above normal for race usually categorizes a patient as having moderate-to-severe GO. Encouraging smoking cessation and achieving euthyroidism in the individual patient are important. Simple treatment measures such as lubricants for lid retraction, nocturnal ointments for incomplete eye closure, prisms in diplopia, or botulinum toxin injections for upper-lid retraction can be effective in mild cases of GO. Glucocorticoids, orbital radiotherapy, and decompression/rehabilitative surgery are generally indicated for moderate-to-severe GO and for sight-threatening optic neuropathy. Future therapies, including rituximab aimed at treating the molecular and immunological basis of GO, are under investigation and hold promise for the future.

Nitrofurantoin-induced hepatotoxicity: a rare yet serious complication.

Abstract: Nitrofurantoin is a commonly prescribed antibiotic for the treatment of recurrent uncomplicated urinary tract infections. Its importance has been emphasized by the current international clinical practice guidelines for the management of uncomplicated cystitis. Since its introduction into clinical practice, nitrofurantoin has been associated with various adverse effects, including hepatotoxicity. We searched the English-language literature using PubMed and SCOPUS for the period 1961 through the end of February 2013. Key search terms included "nitrofurantoin AND hepatotoxicity" as well as "nitrofurantoin AND hepatitis." When studies or case reports were found, we assessed articles cited in those publications. A broad spectrum of liver toxicity associated with nitrofurantoin use has been reported, ranging from acute hepatitis, granulomatous reaction, cholestasis, or autoimmune-mediated hepatitis to chronic active hepatitis that could lead to cirrhosis or death. The mechanism of hepatotoxicity is poorly understood, but it is believed to be the result of an immunologic process or a direct cytotoxic reaction. It has been postulated that prolonged exposure to nitrofurantoin, female sex, advanced age, and reduced renal function increase the risk of developing hepatotoxicity. For the management of severe cases, corticosteroids have been used along with nitrofurantoin discontinuation. Because of mixed results, the utility of corticosteroids has not been proven and should be used judiciously. Given the severity and seriousness of the adverse effect of hepatotoxicity, clinicians should weigh the risks and benefits of nitrofurantoin before initiating therapy, especially in long-term prophylaxis in high-risk patients. Clinicians also should be well versed in recognizing and managing liver injury associated with nitrofurantoin.

Yield of diagnostic tests and its impact on cost in adult patients with syncope presenting to a community hospital.

Abstract: Objectives Total annual costs for syncope-related hospitalizations were $2.4 billion in 2000. The aim of this study was to examine the type and number of tests ordered for patients admitted with syncope and whether these tests helped establish the cause. Methods We studied the records of 1038 patients coded as "syncope" in billing records, and 167 fulfilled the eligibility criteria. The main outcome measures were the diagnostic yield of the ordered tests, the incremental cost/incremental benefit, and the number of admissions that can be averted if risk stratification were used in the evaluation. Results The etiology of the syncope was identified in 48.3% of the patients. Postural blood pressure measurement has the highest diagnostic yield at 58.7%, whereas history taking diagnosed 19.7% of cases. The diagnostic yields of telemetry, electrocardiogram, radionuclide stress test, echocardiography, and troponin measurement were 4.76%, 4.24%, 3.44%, 0.94%, and 0.62%, respectively. Chest x-ray, carotid ultrasonography, 24-hour Holter monitoring, brain computed tomography, and brain magnetic resonance imaging did not yield the diagnosis in any of the patients. Only 1.9% of the money spent in the evaluation of syncope was effective in leading to a definitive diagnosis. The orthostatic blood pressure measurement was ranked first in the incremental cost/incremental benefit ratio and the radionuclide stress test was ranked last (17.03 vs 42,369.0, respectively). Approximately 6% of the patients did not meet the admission criteria. Conclusions Physicians ordered unnecessary tests that have a low yield and are not cost-effective. A standardized algorithmic approach should be the cornerstone in the evaluation of syncope.

Knowledge and management of sports concussions among coaches and certified athletic trainers in Alabama

Abstract: OBJECTIVES: To identify modifiable barriers in resources, knowledge, and management that may improve the care of young athletes with concussions in the state of Alabama. METHODS: An electronic survey was distributed to 2668 middle and high school coaches of contact sports in Alabama, and a paper survey was completed by 79 certified athletic trainers (ATCs) in 2010. Questions focused on their resource availability, knowledge of concussions based on the 2008 Consensus Statement on Concussion in Sport: the 3rd International Conference on Concussion in Sport (commonly known as the Zurich consensus statement), and management of concussions. RESULTS: A total of 402 (16% response rate) coaches and 55 ATCs (70% response rate) responded to the survey. This study highlights that ATC coverage often is limited to the high school level, football, and competitions. Both coaches and ATCs primarily use physicians to make return-to-play decisions, although coaches (43.7%) usually refer to primary care physicians, whereas ATCs (43.6%) refer to orthopedic or sports medicine physicians. The study also revealed that coaches and ATCs desire education and could expand concussion awareness by providing education to parents and athletes. No overall difference was seen in the knowledge and management of concussions between coaches and ATCs; however, ATCs were more likely to identify symptoms that are positive for concussions (P = 0.04). Both groups had difficulty recognizing subtle symptoms such as trouble sleeping, personality changes, and dizziness; they also were unaware that strenuous mental activities could delay concussion recovery, although ATCs scored significantly better than coaches (P CONCLUSIONS: This study describes coaches' and ATCs' varying knowledge and management techniques and highlights areas in which targeted interventions and outreach could be useful. These areas include increased ATC availability, coach/ATC concussion education, improved parent/athlete education, increased "return to think" awareness, and more consistent use of Sports Concussion Assessment Tool 2.

A comprehensive approach to glenohumeral arthritis.

Abstract: Arthritis of the glenohumeral joint is a common cause of debilitating shoulder pain, affecting up to one-third of patients older than 60 years. It is progressive in nature and characterized by irreversible destruction of the humeral head and glenoid articular surfaces. Inflammation of the surrounding soft tissues is often present and further contributes to the pain caused by the disease process. A number of primary (degenerative) and secondary pathological processes may result in this condition. Patients often present with a long history of shoulder pain, stiffness, and/or loss of function, or may have acute exacerbations of this chronic condition. Initial conservative management is aimed at improving pain and restoring function. Surgical treatment is indicated in severe or refractory cases when nonoperative management has failed. Shoulder replacement now accounts for the third most common joint replacement surgery after the hip and knee. This article reviews the basic science and clinical management of osteoarthritis of the glenohumeral joint.

Advance care planning and proxy decision making for patients with advanced Parkinson disease.

Abstract: OBJECTIVES: To examine advance care planning practices and proxy decision making by family healthcare proxies for patients with advanced Parkinson disease (PD). METHODS: Sixty-four spouses and adult children, self-designated as a/the healthcare proxy for advanced patients with PD, participated in a cross-sectional survey study. RESULTS: Sixty patients with PD (95%) had completed a living will, but only 38% had shared the document with a physician. Among three life-support treatments--cardiopulmonary resuscitation (CPR), ventilator, and feeding tube--47% of patients opted for CPR, 16% for ventilator, and 20% for feeding tube. Forty-two percent of proxies did not know patients' preferences for one or more of the three life-support treatments. Only 28% of proxies reported that patients wanted hospice. Patients who shared advance directives with a physician were significantly less likely to choose CPR and a feeding tube and they were more likely to choose hospice. In a hypothetical end-of-life (EOL) scenario, the majority of proxies chose comfort care as the EOL goal of care (53%) and pain and symptom management only as the course of treatment option (72%); these proxy choices for patients, however, were not associated with patients' preferences for life support. Patients' proxies preferred a form of shared decision making with other family members and physicians. CONCLUSIONS: Advance care planning is effective when patients, families, and healthcare professionals together consider future needs for EOL care decisions. Further efforts are needed by healthcare professionals to provide evidence-based education about care options and facilitate advanced discussion and shared decision making by the patient and families.

Canine-assisted therapy in the inpatient setting.

Abstract: Canine-assisted therapy (CAT) is widely used in outpatient settings, yet there is little published literature regarding its use, efficacy, and safety in the inpatient setting. The primary objective of this review was to consolidate published information regarding CAT efficacy and safety in the inpatient population. The secondary objective was to review safety concerns associated with CAT. The databases PubMed, Ovid MEDLINE, and Web of Knowledge were searched using the dates April 2003-April 2013 with the terms "animal assisted therapy" and "pet therapy." Articles were reviewed for the relevance of CAT in the inpatient setting, and those meeting our criteria were included in the study. The references of selected articles also were reviewed and included if study criteria were met. The review of the literature resulted in 429 total articles using the search terms. Of the 429 articles, 177 were duplicates and 218 pertained to the outpatient setting or involved animal therapies other than canine, leaving 34 articles that met the search criteria. The bibliography review of the 34 articles yielded an additional 10 articles. Our review of the literature showed that in the inpatient setting, CAT is an effective therapy among patients of all ages and with various medical problems and is safe, with no transmitted infections reported.

HSV-1 and HSV-2 seroprevalence in the united states among asymptomatic women unaware of any herpes simplex virus infection (Herpevac Trial for Women).

Abstract: Objectives Recent evidence suggests that the epidemiology of herpes simplex viruses (HSVs) is changing because fewer HSV-1 infections are acquired in childhood and increased sexual transmission of HSV-1 is reported. The objective of the study was to assess the seroprevalence of type-specific antibodies to HSV-1 and HSV-2 in the United States. Methods We used the Western blot antibody screening data from a large phase III vaccine efficacy trial (Herpevac Trial for Women) to assess the seroprevalence of type-specific antibodies to HSV-1 and HSV-2 in the United States. Results The antibody status of 29,022 women (>31,000 women interviewed and then had their blood drawn for the HSV testing [29,022 women]) between the ages of 18 and 30 years in the United States revealed that increasing age was associated with increasing seroprevalence to HSV. Overall, in asymptomatic women unaware of any HSV infection, HSV-1/-2 status was positive/negative in 45%, negative/positive in 5%, positive/positive in 7%, negative/negative in 38%, and indeterminate in 5%. HSV-1 infections were more common in Hispanic and non-Hispanic black women and in the US northeast and in individuals living in urban areas. HSV-2 was more common in non-Hispanic black women, the US south, and in urban areas. Conclusions Seronegative status for both HSV-1 and HSV-2 was the second most common finding after positive antibody to HSV-1 but negative antibody to HSV-2. Despite recent changes in genital herpes epidemiology, most women acquired HSV-1 but not HSV-2 infections before 18 years of age. Among participants screened for study participation and who were unaware of any HSV infection, progressively higher prevalence of the HSV-1 or HSV-2 antibody was observed in older subjects. Many women who test positive for HSV-1 and/or HSV-2 are unaware of their status.

Risk factors for inadequate colonoscopy bowel preparations in African Americans and whites at an urban medical center.

Abstract: Colorectal cancer (CRC) is the second leading cause of cancer mortality in the United States, with African Americans having the highest CRC incidence and mortality of all US populations.1 Although colonoscopy is considered the gold standard for CRC screening, its efficacy is dependent on the quality of the procedure, most notably bowel preparation. Suboptimal bowel preparations have been shown to lead to missed adenomatous polyps,2 the precursor for CRC. Poor bowel preparation also has been associated with longer procedure times and a decreased rate of intubating the cecum.3 Moreover, inadequate bowel preparation results in canceled or aborted procedures and repeated examinations or earlier surveillance intervals.2,3 Inadequate bowel preparation has been reported in 15% to 48% of all colonoscopies in a variety of patient populations.2,4–10 Previous studies have identified risk factors associated with an inadequate colonoscopy preparation, including older age,4,5 male sex,4,8 afternoon procedure time,5 Medicaid insurance,4,10 single status,4,10 use of an interpreter,10 and inpatient status.4,8 Most of these studies, however, have not included a large number of African Americans who are at high risk for CRC. Moreover, little is known about the impact of quality measures, including bowel preparation on CRC burden in African Americans. The aim of this study, therefore, was to estimate the prevalence of and risk factors associated with inadequate colonoscopy preparation in a diverse urban population.

Metformin use and the risk of esophageal cancer in Barrett esophagus.

Abstract: OBJECTIVES Diabetes mellitus is a significant risk factor for total cancer incidence and mortality. Metformin, a commonly used antidiabetic drug, has been shown to be protective against different types of cancers; however, its role in esophageal cancer is unknown. The goal of this study was to determine whether the use of metformin modifies the risk of development of esophageal adenocarcinoma in patients with Barrett esophagus. METHODS Patients with diagnoses of Barrett esophagus and esophageal cancer were identified during a 20-year period. Demographic and clinical data were collected. The outcome variable was esophageal adenocarcinoma. Univariate analysis was performed using two-sample t tests for continuous variables or the Fisher exact test for categorical variables. Multiple logistic regression analysis was then performed using the significant variables. RESULTS A total of 583 patients were identified with the diagnosis of Barrett esophagus or esophageal adenocarcinoma from 1992 to 2012. Of these, 115 had esophageal adenocarcinoma and 468 had Barrett esophagus. Age, smoking, and diabetes mellitus were found to be significant risk factors for the development of esophageal cancer with the following results: age (P < 0.001), smoking (P = 0.003), diabetes mellitus (P = 0.007). Statin use was protective against the development of cancer with P = 0.001. Metformin use was neither associated with an increased nor a decreased risk of esophageal cancer. CONCLUSIONS The three independent variables that predicted progression of Barrett esophagus to esophageal adenocarcinoma in our study were older age, smoking, and diabetes mellitus. Statin use showed protective effect against development of esophageal adenocarcinoma. Metformin use did not demonstrate any statistically significant protective effect.

Impact of an academic-community partnership in medical education on community health: evaluation of a novel student-based home visitation program.

Abstract: OBJECTIVES Current US healthcare delivery systems do not adequately address healthcare demands. Physicians are integral but rarely emphasize prevention as a primary tool to change health outcomes. Home visitation is an effective method for changing health outcomes in some populations. The Florida International University Herbert Wertheim College of Medicine Green Family Foundation NeighborhoodHELP service-learning program assigns medical students to be members of interprofessional teams that conduct household visits to determine their healthcare needs. METHODS We performed a prospective evaluation of 330 households randomly assigned to one of two groups: visitation from a student team (intervention group) or limited intervention (control group). The program design allowed randomly selected control households to replace intervention-group households that left the program of their own volition. All of the households were surveyed at baseline and after 1 year of participation in the study. RESULTS After 1 year in the program and after adjustment for confounders, intervention group households proved more likely (P ≤ 0.05) than control households to have undergone physical examinations, blood pressure monitoring, and cervical cytology screenings. Cholesterol screenings and mammograms were borderline significant (P = 0.05 and P = 0.06, respectively). CONCLUSIONS This study supports the value of home visitation by interprofessional student teams as an effective way to increase the use of preventive health measures. The study underscores the important role interprofessional student teams may play in improving the health of US communities, while students concurrently learn about primary prevention and primary care.

Safety and efficacy of percutaneous renal biopsy by physicians-in-training in an academic teaching setting.

Abstract: OBJECTIVES The safety and efficacy of percutaneous renal biopsy (PKB) are relatively little studied in a training setting. We sought to review our recent experience with bedside PKB in our training program. METHODS We performed a retrospective cohort review of our consecutive 2.5-year renal biopsy experience (May 2007-November 2009) at the University of Mississippi Nephrology Fellowship. All of the biopsies were performed exclusively by renal fellows using real-time ultrasound (US) visualization within the framework of a structured US-PKB training course. RESULTS A total of 64 patients underwent PKB during the index period; 50 (78.1%) of these procedures were performed on native kidneys. Participant age was 39.8 ± 13.7 years, blood pressures measured 140.1/85.3 ± 21.5/14.9 mm Hg, serum creatinine was 3.05 ± 3.15 mg/dL, and median random urine protein:creatinine ratio was 2.38 (25%-75% interquartile range 0.49-7.32). The biopsied kidneys measured 11.8 (±1.6) cm. We recovered 18.8 ± 11.5 glomeruli per procedure; two biopsies were unsuccessful. Focal glomerular sclerosis and lupus nephritis (22% and 25%, respectively) predominated among the specimens. Only three specimens returned with no diagnostic changes. There was a close correlation between preceding history and recovered diagnoses of diabetic changes and lupus nephritis (r 0.605 and 0.842; P < 0.0001 for both). Initial hemoglobin of 10.8 ± 1.8 g/dL dropped to 10.2 (1.9) g/dL after the procedure (P < 0.0001). Five (7.8%) patients needed transfusion; one patient experienced persistent urine leakage; however, none of the patients needed surgical or radiological intervention or died. CONCLUSIONS In the setting of a well-structured training environment, US-guided PKB is a reasonably safe and valuable component of renal fellowship training.

Endoscopic mucosal resection recurrence rate for colorectal lesions.

Abstract: Objectives We aimed to evaluate the polyp recurrence rate after endoscopic mucosal resection (EMR) and factors contributing to increased recurrence. Methods MEDLINE (from 1966 to 2013), the Cochrane Central Register of Controlled Trials, and the Scopus database were searched in December 2013. Studies evaluating the polyp recurrence rate after colonic EMR were included. All of the articles were assigned a quality score. Standard forms were used to extract data regarding study design, outcome measures, and adverse effects by two independent reviewers. We performed a meta-analysis with a random effects model. Separate analyses were performed for each main outcome by using odds ratio (OR) and risk difference. Heterogeneity was assessed by I(2) measure of inconsistency. Results For the recurrence rate of colorectal lesions, 30 articles were included, with a total of 3404 patients. The polyp recurrence rate after EMR was 13.1%. Piecemeal resection was associated with a higher recurrence rate compared with en bloc resection (OR 4.39, 95% confidence interval 2.05-9.41; 14 studies). The use of argon plasma coagulation did not affect the polyp recurrence rate (OR 1.23, 95% confidence interval 0.39-3.88). Significant heterogeneity was present among studies. Conclusions The recurrence rate of colorectal polyps after EMR is reasonably low; however, piecemeal resection was associated with a higher recurrence rate than en bloc resection after EMR.

Self-reported versus actual weight and height data contribute to different weight misperception classifications.

Abstract: Approximately 34% of 12- to 19-year-olds are overweight or obese.1 Numerous physical and psychosocial health consequences2,3 and economic costs4 have directed attention to the need for effective prevention/intervention programs. Adolescents who are overweight or obese are significantly more likely than their normal-weight counterparts to misperceive their weight status.5 This is concerning because overweight or obese adolescents who underestimate their weight status have been found to be less motivated to change their weight-related health behaviors.6 Conversely, normal-weight adolescents who overestimate their weight status tend to engage in more harmful weight-related practices7; therefore, future studies examining the potential effects of weight misperception across weight categories, including underweight, are warranted. The literature comparing the use of objective/actual versus subjective/self-reported height and weight measurements in the calculation of body mass index (BMI) is growing. A systematic review8 of 64 studies examining the relation between these two methods of assessment suggests trends of underreporting for weight/BMI and overreporting of height, with some differences based on sex and populations studied. Another literature review9 echoes the results of self-reported data underestimating overweight prevalence and suggests that self-reported data should be used only if these are the sole source of data. These issues are further complicated in the context of defining weight misperception. To date, the most common methodological approach to estimating weight misperception has involved calculating discrepancy scores between perceived weight status (assessed via a single-item question or body/figure silhouettes) and weight status calculated with self-reported6,10–13 or actual weights and heights.14–17 To our knowledge, no studies have directly compared utilization of different methods to define weight misperception, which could affect findings. Other studies have used additional strategies for defining weight misperception such as comparison of differences between self-reported weight versus actual weight18 and perceived weight versus weight status measured by waist circumference.19 The purpose of this study was to examine potential differences between the two most common approaches to defining weight misperception, underestimation and overestimation. Specifically, weight status perception was compared with self-reported weight status and actual weight status based on BMI percentiles calculated from self-reported and actual weights and heights, respectively. Furthermore, the accuracy of assigning weight status based on BMI percentiles calculated from self-reported weights and heights was assessed by comparing it with actual weight status.

EMS patients and walk-in patients presenting with severe sepsis: differences in management and outcome.

Abstract: OBJECTIVES Sepsis is a significant problem. The differences between patients with sepsis who walk into the emergency department (ED) and those who are transported via emergency medical services (EMS) have not been clarified. The aim of the study was to determine whether there was a difference in outcome between patients arriving by EMS and those presenting directly to the ED. METHODS We prospectively collected and reviewed a cohort of all cases of severe sepsis and septic shock admitted to the medical intensive care unit from the ED from November 2009 to March 2012. Extracted data were basic demographic information (including mode of ED arrival), clinical data, and treatments. We calculated Systemic Inflammatory Response Syndrome criteria, Acute Physiology and Chronic Health Evaluation II scores, and Sequential Organ Failure Assessment (SOFA) scores. The primary outcome was mortality in severely ill patients with sepsis. RESULTS A total of 378 subjects (78%) presented by EMS and 107 subjects were walk-in patients (22%). Patients transported via EMS were older (P 4 (P < 0.02), a more altered mental status (P < 0.01), and higher respiratory rates (P < 0.05) than did walk-in patients. Patients transported by EMS had worse disease severity when measured by an Acute Physiology and Chronic Health Evaluation II score (P < 0.01) but not by SOFA score. EMS patients had a shorter time to receiving antibiotics (P = 0.02) and central line placement (P < 0.01) than did walk-in patients. In a logistic model, mortality was associated with increasing age (adjusted odds ratio 1.3; 95% confidence interval [CI] 1.2-1.4), higher first-measured ED lactates (1.2; 95% CI 1.1-1.2), and increased initial SOFA score (adjusted odds ratio 1.2; 95% CI 1.1-1.3) but not EMS arrival or prehospital fluids. CONCLUSIONS Neither arrival by EMS nor fluid administration by EMS is associated with decreased mortality in severe sepsis.

Successful use of intravenous dexmedetomidine for magnetic resonance imaging sedation in autistic children.

Abstract: OBJECTIVES: Autism and autism spectrum disorders (A/ASD) represent a family of neurodevelopmental conditions that are associated with overactive, difficult-to-control behaviors. Sedating these patients for magnetic resonance imaging (MRI) poses challenges. Children with A/ASD were examined against clinical controls to determine the effectiveness and safety of intravenous (IV) dexmedetomidine for deep sedation. METHODS: The quality assurance data on all of the children who received IV dexmedetomidine sedation for MRI between July 2007 and December 2012 were reviewed. Patients in both groups were sedated by an intensivist-based team with a standard plan of 2 μg/kg IV dexmedetomidine administered for 10 minutes followed by an infusion of 1 μg · kg(-1)· hour(-1). The amount of IV dexmedetomidine was titrated to the deep level of sedation. A total of 56 patients in the A/ASD group and 107 in the control group were sedated with no reported sedation failures. Sedation parameters were compared between the A/ASD and control groups using analysis of covariance models, controlling for age, sex, and weight. RESULTS: Children in the A/ASD group were predominantly male (73%) and older (6.1 ± 0.3 years) than children in the control group (56%; 5.0 ± 0.2 years; P < 0.05 for both). Procedure time was significantly shorter for patients in the A/ASD group than in control patients (34.6 ± 2.4 vs 44.3 ± 1.6 minutes; P < 0.05). The A/ASD and control groups required a similar IV bolus of dexmedetomidine (2.6 μg/kg ± 0.1 vs 2.4 μg/kg ± 0.10; P = 0.29), with a significantly lower infusion dose in the A/ASD group (0.74 μg/kg ± 0.05 vs 0.89 μg/kg ± 0.03; P < 0.05). Heart rates were similar in the A/ASD group and the control group (67.0 beats per minute ± 1.6 vs 69.3 ± 1.1 beats per minute; P = 0.250). There were no complications. Recovery time was approximately 7 minutes longer in the A/ASD group than in the control group, but this was nonsignificant (101.2 ± 3.5 minutes vs 94.2 ± 2.4 minutes; P = 0.12). Analyses were performed using analysis of covariance methods and generalized linear models to control for age, sex, and weight. CONCLUSIONS: Children with A/ASD can be successfully sedated for MRIs with IV dexmedetomidine without complications.

Analysis of fall injuries by body mass index.

Abstract: OBJECTIVE: To examine the association of body mass index (BMI) and fall injuries. METHODS: Data were derived from the 2010 Behavioral Risk Factor Surveillance System and included subjects aged 45 years and older from Texas. The outcome was self-reported falls that resulted in injury to the respondents. Analysis of fall injuries by BMI was conducted and standard errors, 95% confidence intervals (CIs), and coefficients of variation were reported. Complex sample multivariate Poisson regression was used to examine the association of BMI and fall injuries. RESULTS: A total of 18,077 subjects were surveyed in 2010, and 13,235 subjects were aged 45 years old and older. The mean BMI was higher (29.94 vs 28.32 kg/m(2)) among those who reported fall injuries compared with those who did not. The fall injuries reported by obese respondents (relative risk [RR] 1.67) were found to be significantly (P = 0.031) higher compared with normal-weight respondents in the multivariate regression. Other risk factors that had significant association with fall injuries (when adjusted for BMI) were activity limitations (RR 5.00, 95% CI 3.36-7.46) compared with no limitations, and not having formal employment (homemaker: RR 2.68, 95% CI 1.33-5.37; unable to work: RR 5.01, 95% CI 1.87-13.29; out of work and students: RR 3.21, 95% CI 1.41-7.29) compared with the employed population. CONCLUSIONS: There is a significant association between obesity and fall injuries in adults aged 45 years old and older in Texas. Interventions in fall prevention, although generally targeted at present to older adults, also should take into account the weight status of the subjects. Language: en

Prenatal care, pregnancy outcomes, and postpartum birth control plans among pregnant women with opiate addictions.

Abstract: Objectives To describe how effectively we provided adequate prenatal care and postpartum contraception to prevent repeat, unintended pregnancies to women using opiates or medication maintenance therapy (MMT) during pregnancy. Methods We conducted a retrospective chart review of 94 women using opiates or MMT during 96 pregnancies while receiving prenatal care in the regional high-risk maternity care clinic between July 2010 and June 2012. We examined prenatal care usage, birth outcomes, and postpartum contraception using χ(2), Kruskal-Wallis, and binary logistic regression modeling. Results Patients were predominately white (93.6%), multiparous (75.5%), and in their 20s; 71 (74%) used MMT and 25 (26%) used prescribed or illicit opiates. Fewer than half (44% [46.2%]) received any documented prenatal counseling about postpartum contraception. Sixteen (17%) babies were premature. Sixty-four (66.7%) infants were diagnosed as having neonatal abstinence syndrome (NAS). Only 42 (43.8%) women attended their postpartum visits. Overall, 60 (62.5%) women received postpartum contraception. The only significant predictors of postpartum contraception use were preterm birth and postpartum appointment attendance. Conclusions Alternative strategies for providing postpartum care should be explored because women using opiates or MMT during pregnancy are significantly more likely to use postpartum contraception if they attend their postpartum appointments.

Perceptions of companion dog benefits on well-being of US military veterans with HIV/AIDS.

Abstract: Objectives Patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) frequently experience psychosocial complications in addition to physical illness. Conflicting data on the value of companion dog ownership in minimizing psychosocial distress suggest the need for more research in this field. This study helps to clarify and expand upon previous research on perceived well-being among patients with HIV/AIDS, specifically as it relates to how owning dogs influences the well-being of US military veterans living with HIV/AIDS. Methods Twenty-nine male veterans with a mean age of 52 years who reported having owned a dog since being diagnosed as having HIV/AIDS completed semistructured interviews regarding pet ownership and perceived well-being. Participants also completed a brief survey describing their pets and rating scales that assessed symptoms of depression (nine-question Patient Health Questionnaire-9) and the extent of attachment to their pets (Lexington Attachment to Pets Scale). Descriptive statistics were completed and interview responses were transcribed and examined qualitatively for key themes. Results The mean Patient Health Questionnaire-9 score of 8.9 (median score of 6) was consistent with mild depressive symptoms, and the mean Lexington Attachment to Pets Scale score was 83.2, indicative of high attachment to one's dog. Veterans reported walking their dogs a mean of 49 minutes/day. Qualitative analysis of the interviews showed that having HIV/AIDS interfered with well-being in three main ways (emotional burden, physical condition, and social isolation). Owning dogs enhanced perceived well-being in four ways (physical activity, companionship, responsibility, and stress reduction). Conclusions Twenty-eight of the 29 participants (97%) reported that owning dogs was a positive experience. Overall, this study suggests that veterans with HIV/AIDS who own companion dogs believe that it improves their well-being.

Factors associated with placement of rural primary care physicians in North Carolina.

Abstract: Objectives The objective of this study was to determine what factors influence primary care physicians to choose rural practice locations to better develop the rural workforce in North Carolina. To better recruit and retain physicians, residents, and medical students for rural practice, we must understand what factors positively influence their choice of practice location. Methods A survey was sent to all primary care physicians licensed in the state of North Carolina (N = 2829), with 975 usable (return rate 34.5%). Results were analyzed using basic descriptive statistics and χ(2) automatic interaction detection analysis. Results Findings indicated that solo practice, critical access hospital, community health center, or federally qualified health center sites were strongly associated with rural practice. Pay as a factor in choosing a work site, financial support from a hospital, and medical school loan repayment also was correlated with rural practice. Seventy-two percent of rural physicians reported being raised in a town of ≤11,000, which was found to be highly associated with working in a rural area. This single point is highly indicative of rural practice and by defining this new level it roughly doubles the predictive value previously defined by other researchers. Conclusions Incentives such as loan repayment, salary guarantees, and practice assistance for rural physicians currently provided under several federal and state programs should continue to assist in attracting primary care physicians to rural areas. Having been raised in an area of ≤11,000 was highly predictive of future rural medical practice and could be used in the recruitment of physicians and residents to increase the ultimate yield for rural areas. With these new data, North Carolina medical schools and practices serving rural areas may be able to better recruit and retain physicians with a predilection to rural practice.

Geographic variations of racial/ethnic disparities in cervical cancer mortality in Texas.

Abstract: Objectives To examine how racial/ethnic disparities of cervical cancer mortality vary geographically and to identify factors contributing to the variation. Methods Using the population-weighted risk difference, the authors investigated geographic patterns of racial/ethnic disparities in cervical cancer mortality in Texas based on data from 1995 to 2008 georeferenced at the census tract level. In addition, we considered the impact of seven factors--stage at diagnosis, spatial access to health care, and five factors that were created from available demographic data: socioeconomic status (SES), the sociodemographic factor, the percentage of African Americans, the health insurance factor, and the behavioral factor--on racial/ethnic disparities in the analysis using multivariate logistic regression. Results SES, the sociodemographic factor, the percentage of African Americans, and racial/ethnic disparities in late-stage diagnosis in a census tract were independent predictors of a census tract's displaying significant racial/ethnic disparities in cervical cancer mortality. Compared with a census tract with the highest SES, a census tract with the lowest SES was more likely to have higher mortality rates in African Americans (odds ratio 4.19, confidence interval 2.18-8.07) or Hispanics (odds ratio 8.15, confidence interval 5.27-12.61) than non-Hispanic whites after adjusting for covariates. Health insurance expenditures also influenced racial/ethnic disparities in mortality, although this effect was attenuated after adjusting for covariates. Neither our calculated behavioral factor nor spatial analysis of access to health care explained racial/ethnic gaps in mortality. Conclusions Findings from this study could allow cervical cancer intervention programs to more clearly identify areas that would reduce disparities in cervical cancer outcomes.

Attitudes toward self-sampling for cervical cancer screening among primary care attendees living on the US-Mexico border.

Abstract: BACKGROUND Hispanic women living along the US border with Mexico have one of the highest cervical cancer mortality rates in the nation, owing in part to lower rates of screening. The barriers to screening in this population include lack of access to care and fear of and embarrassment about the pelvic examination. Screening for oncogenic or high-risk human papillomavirus during cervical cytology has been added to screening recommendations. A novel method for human papillomavirus testing is self-sampling, in which women collect their own cervicovaginal samples. There is lack of information about the acceptability of self-sampling as an alternative to cytology for cervical cancer screening in women living along the US-Mexico border. METHODS We conducted five focus groups with women between the ages of 30 and 65 who were primary care patients of clinics along the US-Mexico border. We used constructs from different health behavioral theories as a framework for the interview guide. RESULTS A total of 21 women participated in the focus groups, 80% of whom were Hispanic; mean age was 53.4 (standard deviation 7.9). More than one-third (38%) of the participants had not undergone a Papanicolaou test in the last 3 years. Women identified the perceived benefits of self-sampling as ease, convenience, practicability, less embarrassment, and need for child care as compared with a Papanicolaou test. The main barrier to self-sampling was concern about not performing the test correctly. CONCLUSIONS In this qualitative study, we found positive attitudes toward self-sampling among women living along the US border with Mexico. Further research is needed to evaluate interventions that address women's low levels of self-efficacy to perform the test and to evaluate the effectiveness of self-sampling in increasing cervical cancer screening rates.

Association of body mass index and waist circumference with subclinical atherosclerosis in retired NFL players.

Abstract: OBJECTIVES: It is unknown which measure of adiposity (body mass index [BMI] or waist circumference [WC]) is associated with subclinical atherosclerosis in retired National Football League (NFL) players and whether this relation is attenuated after adjusting for components of the metabolic syndrome (elevated triglycerides, fasting glucose, and low levels of high-density lipoprotein-cholesterol [HDL-C]) that frequently coexist with obesity. METHODS: Coronary artery calcium (CAC) was measured in 926 retired NFL players. BMI was calculated as weight (in kilograms)/height (in meters)(2) and WC was measured in inches. Logistic regression analyses adjusting for age, race, systolic blood pressure, high sensitivity C-reactive protein, triglycerides, HDL-C, and fasting blood glucose were performed to evaluate whether BMI or WC was independently associated with the presence of CAC (CAC score >0). RESULTS: The median age, BMI and WC were 54 years, 31 kg/m(2), and 40 inches, respectively. CAC was present in 61% (n = 562) of retired players. Adjusting for age, race, systolic blood pressure, high sensitivity C-reactive protein, triglycerides, HDL-C, and fasting blood glucose, each standard deviation increase in BMI (4.85 kg/m(2)) was significantly associated with CAC (odds ratio [OR] 1.25, 95% confidence interval [CI] 1.03-1.50), but each standard deviation increase in WC (10.53 inches) was not significantly associated with CAC (OR 1.18, 95% CI 0.96-1.45). There was a significant association for the presence of CAC for highest versus lowest quartiles of both BMI (OR 1.93, 95% CI 1.13-3.28) and WC (OR 1.75, 95% CI 1.05-2.92), although the trend for the presence of CAC was significant only across increasing BMI quartiles, even in models that included WC. CONCLUSIONS: In retired NFL players both BMI and WC were associated with CAC. Higher BMI may be associated with an increasing trend for the presence of CAC independent of WC.
