'Sedentary behaviour counselling': the next step in lifestyle counselling in primary care; pilot findings from the Rapid Assessment Disuse Index (RADI) study.

BACKGROUND: Accumulating evidence emphasises a relationship between prolonged sitting and increased risk for cardiometabolic disorders and premature death irrespective of the protective effects of physical activity. Primary care physicians have the potential to play a key role in modifying patients' sedentary behaviour alongside physical activity. METHODS: A pilot study examining sedentary behaviour and physical activity counselling in a primary care clinic. A total of 157 patients completed a detailed survey related to lifestyle counselling received from their primary care physician. We analysed these responses to describe counselling practices within the 5A framework, and to examine correlates (ie, patients' demographics, sedentary behaviour and physical activity and clinical variables) related to receiving counselling. RESULTS: A total of 10% received general advice to decrease sitting time, in comparison with 53% receiving general physical activity counselling. None, however, received a written plan pertaining to sedentary behaviour whereas 14% received a written physical activity prescription. Only 2% were provided with specific strategies for sedentary behaviour change in comparison with 10% for physical activity change. Multivariable analysis revealed that patients who were obese were more likely to receive counselling to decrease sitting (OR=7.0; 95% CI 1.4 to 35.2). In comparison, higher odds for receiving physical activity counselling were associated with being younger, aged 40-59 years (OR=2.4; 95% CI 1.1 to 5.4); and being a non-smoker (OR=6.1; 95% CI 1.3 to 28.4). CONCLUSIONS: This study is the first to assess sedentary behaviour counselling practices in primary care and such practices appear to be infrequent. Future research should attempt to establish a 'knowledge base' to inform development of sedentary behaviour interventions, which should be followed by testing feasibility, efficacy, and subsequent effectiveness of these programmes in a clinical setting.

Social Connectedness, Physical Distancing, and Anxiety in Complying with Shelter-In-Place Orders and Advisories during the Once-In-A-Century COVID-19 Pandemic in the US: A Study of Social Media and Internet Users.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease (COVID-19), was first identified in Wuhan, China, in December 2019. As of 20 October 2020, the virus had infected 8,202,552 people, with 220,061 deaths in US, and in countries around the world, over 38 million people have become infected and over one million have died. The virus usually spreads via respiratory droplets from an infected person. At the time of compiling this paper, while countries around the world are still striving to find a "pharmaceutical intervention (PI)", including treatments and vaccines, they are left with only "non-pharmaceutical interventions (NPIs)", such as physical distancing, wearing masks, and maintaining personal hygiene. In the US, all 50 states, the District of Columbia, and five US territories issued mandatory stay-at-home orders between March 1 and 31 May 2020 to lower the risk of virus transmission. This study empirically examined how social connectedness and anxiety interact with shelter-in-place compliance and advisories during the pandemic. The study collected information from 494 adults using an online survey during April and July 2020.

The importance of implementing inpatient virtual coverage in an endocrinology practice: lessons learned thus far from the COVID-19 pandemic.

The COVID-19 pandemic has rapidly changed the landscape of medical care and the healthcare system needs to quickly adapt in order to continue providing optimal medical care to hospitalized patients in an efficient, effective, and safe manner. Endocrinology diseases are commonly present in patients with COVID-19 and often are major risk factors for development of severe disease. The use of electronic consultation and telemedicine have already been well-established in the outpatient setting but yet not commonly implemented in the inpatient arena. This type of remote medical care has the potential to provide a reliable delivery of endocrine care while protecting providers and patients from spreading infection. This short review intends to provide the initial steps for the development of an inpatient telemedicine endocrine service to patients with endocrine diseases. Telehealth will become part of our daily practices and has a potential to provide a safe and efficient method of consultative service.

Safety of the APOLLO Onyx delivery microcatheter for embolization of brain arteriovenous malformations: results from a prospective post-market study.

BACKGROUND: Catheter retention and difficulty in retrieval have been observed during embolization of brain arteriovenous malformations (bAVMs) with the Onyx liquid embolic system (Onyx). The Apollo Onyx delivery microcatheter (Apollo) is a single lumen catheter designed for controlled delivery of Onyx into the neurovasculature, with a detachable distal tip to aid catheter retrieval. This study evaluates the safety of the Apollo for delivery of Onyx during embolization of bAVMs. METHODS: This was a prospective, non-randomized, single-arm, multicenter, post-market study of patients with a bAVM who underwent Onyx embolization with the Apollo between May 2015 and February 2018. The primary endpoint was any catheter-related adverse event (AE) at 30 days, such as unintentional tip detachment or malfunction with clinical sequelae, or retained catheter. Procedure-related AEs (untoward medical occurrence, disease, injury, or clinical signs) and serious AEs (life threatening illness or injury, permanent physiological impairment, hospitalization, or requiring intervention) were also recorded. RESULTS: A total of 112 patients were enrolled (mean age 44.1±17.6 years, 56.3% men), and 201 Apollo devices were used in 142 embolization procedures. The mean Spetzler-Martin grade was 2.38. The primary endpoint was not observed (0/112, 0%). The catheter tip detached during 83 (58.5%) procedures, of which 2 (2.4%) were unintentional and did not result in clinical sequelae. At 30 days, procedure related AEs occurred in 26 (23.2%) patients, and procedure-related serious AEs in 12 (10.7%). At 12 months, there were 3 (2.7%) mortalities, including 2 (1.8%) neurological deaths, none of which were device-related. CONCLUSION: This study demonstrates the safety of Apollo for Onyx embolization of bAVMs. CLINICAL TRIAL REGISTRATION: CNCT02378883.

Community-based colorectal cancer screening trials with multi-ethnic groups: a systematic review.

The objective of this review was to summarize the current literature of community-based colorectal cancer screening randomized controlled trials with multi-ethnic groups. The CDC reports 40% of adults do not receive time-appropriate colorectal cancer screening. Although overall screening rates have improved since 2000, disparities remain. Studies examining community characteristics may offer insight into improving screening rates and eliminating disparities. We identified community-based colorectal cancer screening studies using PubMed and Ovid Medline database searches. Inclusion criteria were: community-based, randomized controlled trials; English language; published from 1/2001 to 8/2009; all colorectal cancer screening test interventions recommended in the 2008 "Joint Consensus" report; and study participants from at least two racial/ethnic groups, with not more than 90% representation from one group. There were 29 relevant articles published during 2001-2009; with 15 meeting inclusion criteria. We categorized the final studies (n = 15) into the four categories of Patient mailings (n = 3), Telephone outreach (n = 3), Electronic/multimedia (n = 4), and Counseling/community education (n = 5). Of 15 studies, 11 (73%) demonstrated increased screening rates for the intervention group compared to controls, including all studies (100%) from the Patient mailings and Telephone outreach groups, 4 of 5 (80%) Counseling/community education studies, and 1 of 4 (25%) Electronic/multimedia interventions. Patient choice and tailoring of information were common features of trials that increased screening rates across study categories. Including community-level factors and social context may be useful in future design and evaluation of colorectal cancer interventions to reduce or prevent new cases of colorectal cancer.

Do electronic health records help or hinder medical education?

Many countries worldwide are digitizing patients' medical records. What impact will these electronic health records have upon medical education? This debate examines the threats and opportunities.

First-year medical students can demonstrate EHR-specific communication skills: a control-group study.

BACKGROUND AND OBJECTIVES: Graduating medical students will universally use electronic health records (EHRs), yet a June 2007 literature search revealed no descriptions of EHR-specific communication skills curricula in US medical schools. We designed and tested methods to teach first-year medical students to optimally integrate EHRs into physician-patient communication in ambulatory encounters. METHODS: We randomly assigned 17 volunteer students to control (n=8) and intervention (n=9) groups. Both groups learned the mechanics of documenting patient histories using the EHR. Additionally, we taught the intervention group EHR-specific communications skills using guided discovery, brief didactics, and practice role plays. We compared both groups' general and EHR-specific communications skills using a standardized patient (SP) case. RESULTS: Students receiving EHR communication skills training performed significantly better than controls in six of 10 EHR communication skills. In 10 of 11 general communication skills, there were no significant differences between groups. CONCLUSIONS: First-year medical students can demonstrate EHR communication skills early in their medical training. However, in our setting, students did not spontaneously demonstrate EHR skills without instruction, and such skills did not correlate with general communication skills.

Providing access to specialty care for severely disabled institutional residents: an academic health center telemedicine model.

The UT Southwestern Virtual Wound Care Clinic provides care to disabled institutional residents in an urban setting. The program offers flexible financial mechanisms for residents of the facility to access specialty care. Telemedicine improves quality-of-life and reduces costs by minimizing patient transportation. The exchange of clinical knowledge benefits both parties.

Tailored information increases patient/physician discussion of colon cancer risk and testing: The Cancer Risk Intake System trial.

Assess whether receipt of tailored printouts generated by the Cancer Risk Intake System (CRIS) - a touch-screen computer program that collects data from patients and generates printouts for patients and physicians - results in more reported patient-provider discussions about colorectal cancer (CRC) risk and screening than receipt of non-tailored information. Cluster-randomized trial, randomized by physician, with data collected via CRIS prior to visit and 2-week follow-up telephone survey among 623 patients. Patients aged 25-75 with upcoming primary-care visits and eligible for, but currently non-adherent to CRC screening guidelines. Patient-reported discussions with providers about CRC risk and testing. Tailored recipients were more likely to report patient-physician discussions about personal and familial risk, stool testing, and colonoscopy (all p < 0.05). Tailored recipients were more likely to report discussions of: chances of getting cancer (+ 10%); family history (+ 15%); stool testing (+ 9%); and colonoscopy (+ 8%) (all p < 0.05). CRIS is a promising strategy for facilitating discussions about testing in primary-care settings.

Endocrine disturbances in empty sella syndrome: case reports and review of literature.

OBJECTIVE: To report 5 cases of empty sella syndrome (ESS) manifesting with various degrees of pituitary dysfunction. METHODS: We describe the initial manifestations in 5 patients with primary ESS and in previous cases of ESS reported in the English language literature. RESULTS: Review of our recent medical records identified 5 patients referred for evaluation of pituitary deficiencies in whom ESS was diagnosed. Glucocorticoid replacement was required in 3 patients, 2 of whom presented initially with symptoms of severe glucocorticoid deficiency. In each case, magnetic resonance imaging of the brain demonstrated an empty sella. CONCLUSION: Our cases suggest that endocrine abnormalities are not rare as the initial manifestation of ESS and that, contrary to many studies in the literature, the endocrine abnormalities may be quite severe.

Impact of Risk Assessment and Tailored versus Nontailored Risk Information on Colorectal Cancer Testing in Primary Care: A Randomized Controlled Trial.

BACKGROUND: Colorectal cancer screening is effective but underused. Guidelines for which tests are recommended and at what intervals depend on specific risks. We developed a tablet-based Cancer Risk Intake System (CRIS) that asks questions about risk prior to appointments and generates tailored printouts for patients and physicians summarizing and matching risk factors with guideline-based recommendations. METHODS: Randomized controlled trial among patients who: (i) used CRIS and they and their physicians received tailored printouts; (ii) used CRIS to answer questions but received standard information about cancer screening while their physicians received a standard electronic chart prompt indicating they were age-eligible but not currently adherent for colorectal cancer screening; or (iii) comprised a no-contact group that neither used CRIS nor received any information while their physicians received the standard prompt. Participation in testing was assessed via electronic medical record at 12 months. RESULTS: Participation in any colorectal cancer testing was three times higher for those who used the CRIS and received any printed materials, compared with no-contact controls (47% vs. 16%; P < 0.0001). Among CRIS users ages 50 and older, participation in any testing was higher in the tailored group (53% vs. 44%, P = 0.023). CONCLUSION: Use of CRIS and receipt of any information facilitated participation in testing. There was more testing participation in the CRIS-tailored than nontailored group. IMPACT: Asking patients questions about their specific risk factors and giving them and their providers information just prior to an appointment may increase participation in colorectal cancer testing. Tailoring the information has some added benefit.

Accuracy of endoscopic ultrasound in the evaluation of cystic pancreatic neoplasms: a community hospital experience.

OBJECTIVES: Reports on the use of endoscopic ultrasound (EUS) in differentiating benign, premalignant, and malignant pancreatic lesions have been widely variable, particularly with cystic neoplasms. We evaluated the use of EUS for cystic pancreatic lesions in a community hospital setting. METHODS: All patients who underwent EUS for cystic pancreatic neoplasms from 2007 to 2010 were reviewed. A final EUS diagnosis was determined based on the examiner's impression and fine-needle aspiration results if available. Lesions were stratified as benign, premalignant, or malignant. Patients underwent surgical resection, serial imaging studies, or medical oncology/palliative care consultation as indicated. RESULTS: One hundred eighteen patients with cystic pancreatic lesions underwent EUS during the study period. Endoscopic ultrasound diagnoses included 75 benign (63.6%), 35 premalignant (29.7%), and 8 malignant (4.2%) lesions. Thirty-eight patients (32.2%) underwent surgery, 77 (65.3%) were monitored with imaging, and 3 (2.5%) had unresectable malignancies. Elevated carcinoembryonic antigen levels showed a trend toward predicting mucinous cysts (P = 0.062). Accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for cystic lesions were 87.3%, 86.8%, 87.5%, 76.7%, and 93.3%, respectively. CONCLUSIONS: Endoscopic ultrasound is a valuable diagnostic modality in the evaluation of cystic pancreatic neoplasms in a community hospital setting.

Effective use of e-grading in the dental simulation clinic.

The purpose of this article is to describe the development and implementation of a grading software system, accessible from any platform, that engages today's generation of students and replaces paper grading. Set up at one U.S. dental school in an all-access, anytime (24/7) web-based program accessed through tablets, the software allows for a comparison between students' self-grading and instructor grading. This comparison facilitates student-faculty interaction, promoting discussion and student learning. The software can also be used for practical examination grading in which blinded grading between instructors is possible. The data gathered can produce descriptive reports students can draw upon to encourage self-learning and guided learning, propelling students to a better understanding of critical principles as they progress through multiple psychomotor skill sets. Other reports generated by the software allow for instructor calibration, exporting of grades directly into the university grading report system, and visual analysis of trends within each class. In a post-course survey, students (56 percent response rate) and faculty (79 percent response rate) agreed that the electronic grading was more efficient and allowed more time for faculty-student interaction than the previous grading system, thus creating an environment more conducive to learning. Overall, the software has improved students' perception of enhanced kinetic skills, while facilitating administration of preclinical projects and practical examinations.

Esophagectomy outcomes at a mid-volume cancer center utilizing prospective multidisciplinary care and a 2-surgeon team approach.

BACKGROUND: Esophagectomy is associated with high morbidity and mortality, leading to calls for restricted performance at high-volume centers. METHODS: Patients with esophageal cancer were evaluated prospectively in a multidisciplinary tumor board from January 2012 - December 2012. A 2-surgeon team was utilized and detailed outcomes were assessed prospectively. RESULTS: Thirty-one patients underwent esophagectomy, 20 patients underwent laparoscopic transhiatal (65%) approach, and 11 patients underwent laparoscopically assisted Ivor-Lewis (35%) approach. Eighty-one percent of the patients were male, with a median age of 64 years (range: 35 to 83 years) and 73% of the patients had adenocarcinoma. Neoadjuvant chemoradiation was performed in 79% of the patients. R0 resection was achieved in 29 (94%) patients, median nodes identified were 15. Major complications (grade III to V) occurred in 13 (42%) patients and did not correlate with surgical techniques, anastomotic leak occurred in 5 (16%) patients, and significant pulmonary complications occurred in 11 (35%) patients. The length of stay at the hospital was 10 days, readmission rate 23%, and 30-day mortality rate 6%. CONCLUSIONS: High-quality esophagectomy can be performed safely at a mid-volume cancer center. Our outcomes question the reliance on volume alone as an indicator of cancer surgical quality.

Multilevel correlates for human papillomavirus vaccination of adolescent girls attending safety net clinics.

BACKGROUND: Adolescent HPV vaccination in minority and low income populations with high cervical cancer incidence and mortality could reduce disparities. Safety-net primary care clinics are a key delivery site for improving vaccination rates in these populations. PURPOSE: To examine prevalence of HPV initiation (≥ 1 dose), completion (receipt of dose 3 within 12 months of initiation), and receipt of 3 doses in four safety-net clinics as well as individual-, household-, and clinic-level correlates of initiation. METHODS: We used multilevel modeling to investigate HPV initiation among 700 adolescent females who sought primary care in four safety-net clinics in Dallas, Texas from March 2007 to December 2009. Data were abstracted from patients' paper and electronic medical records. RESULTS: HPV vaccine uptake varied significantly by clinic. Across clinics, initiation was 36.6% and completion was 39.7% among those who initiated. In the total study population, only 15.7% received all three doses. In multivariate, two-level logistic regression analyses, initiation was associated with receipt of other adolescent vaccines, influenza vaccination in the year prior to data abstraction, being sexually active, and having more chart documentation (presence of health maintenance questionnaire and/or immunization record). There was no association between initiation and age, race/ethnicity, or insurance status. CONCLUSIONS: In four urban safety-net clinics, HPV initiation rates paralleled 2008 national rates. The correlation of HPV initiation with other adolescent vaccines underscores the importance of reviewing vaccination status at every health care visit. HPV vaccine uptake in safety-net clinics should continue to be monitored to understand impact on cervical cancer disparities.

A validated cultural competence curriculum for US pediatric clerkships.

OBJECTIVE: A 2006 national survey of pediatric clerkship directors revealed that only 25% taught cultural competence, but 81% expressed interest in a validated cultural competence curriculum. The authors designed and evaluated a multi-modality cultural competence curriculum for pediatric clerkships including a validated cultural knowledge test. METHODS: Curriculum content included two interactive workshops, multimedia web cases, and a Cultural and Linguistic Competence Pocket Guide. Evaluation included a student satisfaction survey, a Nominal Technique Focus Group, and a validated knowledge test. The knowledge test comprised 6 case studies with 49 multiple choice items covering the curricular content. RESULTS: Of 149/160 (93%) students who completed satisfaction surveys using a 5-point Likert scale, >82% strongly agreed or agreed that the curricular intervention was a meaningful experience (93%), increased their understanding of the culture of medicine (91%), increased their knowledge of racial and ethnic disparities (89%) and core cultural issues (91%), and improved their skills in working with interpreters (90%) and cross-cultural communication (82%). Top strengths identified by a focus group (34 students) included learning about interpreters, examples of cultural practices, and raised cultural awareness. Pre- and post-knowledge test scores improved by 17% (p<.0001). After six administrations, the test achieved the target reliability of .7. CONCLUSIONS: The authors successfully designed and validated a practical cultural competence curriculum for pediatric clerkships that meets the need demonstrated in the 2006 national survey. PRACTICE IMPLICATIONS: This curriculum will enable pediatric clerkship directors to equip more graduates to provide culturally sensitive pediatric care to an increasingly diverse US population.

Evaluation of a web-based family medicine case library for self-directed learning in a third-year clerkship.

BACKGROUND AND OBJECTIVES: Web-based cases are well accepted by medical students and enable faculty to deliver equivalent educational experiences to all students. A 2009 literature search revealed no study investigating student use patterns of Web-based case libraries for self-directed learning. We investigated third-year students' use of a Web-based case program for self-directed learning in a family medicine clerkship. METHODS: We analyzed Design A Case usage patterns of 210 medical students during academic year 2008--2009. We compared board score differences between these students and those from the previous 5 years who did not use Design A Case. We analyzed data from a 13-item survey, administered to a subgroup of 85 students, about the strengths, weaknesses, and acceptability of the program. RESULTS: Students completed, on average, four cases, which was beyond the requirement of three. They reported that the content was highly relevant to cases they saw in clinic. Almost 75% preferred the self-directed Web-based learning over didactics, and most (64%) felt they learned more electronically. Use of the cases was associated with equivalent Board scores versus didactic lectures. CONCLUSIONS: In our setting, self-directed learning using a Web-based case program was highly acceptable to students. Web-based cases may provide an option for family medicine educators who wish to deliver equivalent educational experiences across sites.

Elevation of osteopontin levels in brain tumor cells reduces burden and promotes survival through the inhibition of cell dispersal.

Osteopontin (OPN) is a pleotrophic molecule that has been associated with multiple disorders of the central nervous system (CNS). Its roles in CNS malignancy are unclear but suggest that higher levels of OPN expression correlate with increased tumor grade and increased migratory capacity of tumor cells. In this study OPN cDNA was cloned into a retroviral vector and used to infect F98 Fischer rat-derived glioma cells and U87 human-derived glioblastoma multiforme (GBM) cells in vitro. Cells expressing high levels of OPN migrated less distance than control cells in vitro. This effect was not RGD mediated, but was reversed in the presence of c-Jun N-terminal kinase (JNK) inhibitor suggesting that JNK1 is an essential component of a negative feedback loop affecting OPN activated signaling cascades. Implantation of tumor cells expressing high levels of OPN into adult Fischer rats and nude rats resulted in morphologically distinct tumors and prolonged host survival relative to controls. We propose that local produced, high level OPN expression limits the malignant character of glioma cells and that the downstream mechanisms involved represent pathways that may have therapeutic value in the treatment of human CNS malignancy.

Syndrome of inappropriate antidiuretic hormone secretion associated with coproporphyria: case report and review of literature.

OBJECTIVE: To remind physicians to consider the hepatic porphyrias in the differential diagnosis of the syndrome of inappropriate antidiuretic hormone secretion. METHODS: We present a case report of a patient seen in the hospital for severe hyponatremia, who was discovered to have the syndrome of inappropriate antidiuretic hormone secretion attributable to coproporphyria. Results of laboratory tests of the patient and her family are presented. RESULTS: A 54-year-old woman was seen in the hospital because of severe hyponatremia accompanied by generalized seizures. Her serum sodium concentration was 112 mEq/L, with concomitant serum and urine osmolalities of 235 and 639 mOsm/kg, respectively. Renal, thyroid, and adrenal functions were normal. Brain, chest, abdominal, and pelvic imaging studies were negative for occult malignant disease. Urinary excretions of porphobilinogen and aminolevulinic acid were substantially elevated. Results of follow-up urine, plasma, and fecal porphyrin studies were consistent with coproporphyria. Results of porphyrin metabolic studies of the patient's family showed normal findings in her parents and a minimally increased fecal coproporphyrin concentration and urinary uroporphyrin excretion in her sister. CONCLUSION: An endocrinology consultation is often requested for patients with hyponatremia. It is important to consider the acute hepatic porphyrias in the differential diagnosis, even though these are rare disorders and the family history may not always be helpful because of the high frequency of asymptomatic carriers.
