Abstract
PURPOSE To analyze faculty experiences regarding facilitating discussions as part of the institution's curriculum on racial and ethnic implicit bias recognition and management. METHOD Between July 2014 and September 2016, the authors conducted 21 in-depth interviews with faculty who had experience teaching in implicit bias instruction or were interested in facilitating discussions related to implicit bias and the Implicit Association Test. Grounded theory methodology was used to analyze interview transcripts. RESULTS Participants identified challenges that affect their ability to facilitate instruction in implicit bias. Faculty described the influence of their own background and identities as well as the influence of institutional values on their ability to facilitate implicit bias discussions. They noted the impact of resistant learners and faculty during discussions and made suggestions for institutional measures including the need for implementation of formalized longitudinal implicit bias curricula and faculty development. CONCLUSIONS Faculty facilitating sessions on implicit bias must attend faculty development sessions to be equipped to deal with some of the challenges they may face. Buy-in from institutional leadership is essential for successful implementation of implicit bias teaching, and medical educators need to consider formalized longitudinal curricula addressing the recognition and management of implicit biases.

Abstract
OBJECTIVE Patients describe feelings of bias and prejudice in clinical encounters; however, their perspectives on restoring the encounter once bias is perceived are not known. Implicit bias has emerged as a target for curricular interventions. In order to inform the design of novel patient-centered curricular interventions, this study explores patients' perceptions of bias, and suggestions for restoring relationships if bias is perceived. METHODS The authors conducted bilingual focus groups with purposive sampling of self-identified Black and Latino community members in the US. Data were analyzed using grounded theory. RESULTS Ten focus groups (in English (6) and Spanish (4)) with N = 74 participants occurred. Data analysis revealed multiple influences patients' perception of bias in their physician encounters. The theory emerging from the analysis suggests if bias is perceived, the outcome of the encounter can still be positive. A positive or negative outcome depends on whether the physician acknowledges this perceived bias or not, and his or her subsequent actions. CONCLUSIONS Participant lived experience and physician behaviors influence perceptions of bias, however clinical relationships can be restored following perceived bias. PRACTICE IMPLICATIONS Providers might benefit from skill development in the recognition and acknowledgement of perceived bias in order to restore patient-provider relationships.

Abstract
The Bronx Ongoing Pediatric Screening (BOPS) project sought to improve screening for sexual activity and sexually transmitted infections (gonorrhea and chlamydia [GCC] and HIV) in a primary care network, employing a modified learning collaborative, real-time clinical data feedback to practices, improvement coaching, and a pay-for-quality monetary incentive. Outcomes are compared for 11 BOPS-participating sites and 10 non-participating sites. The quarterly median rate for documenting sexual activity status increased from 55% to 88% (BOPS sites) and from 13% to 74% (non-BOPS sites). GCC screening of sexually active youth increased at BOPS and non-BOPS sites. Screening at non-health care maintenance visits improved more at BOPS than non-BOPS sites. Data from nonparticipating sites suggests that introduction of an adolescent EMR template or other factors improved screening rates regardless of BOPS participation; BOPS activities appear to promote additional improvement of screening during non-health maintenance visits.

Abstract
The most prominent structural components in bone are collagen and mineral. However, bone additionally contains a substantial amount of noncollagenous proteins (most notably of the SIBLING protein family), some of which may act as cohesive/adhesive "binders" for the composite hybrid collagen/mineral scaffolding, whether in the bulk phase of bone, or at its interfaces. One such noncollagenous protein - osteopontin (OPN) - appears to be critical to the deformability and fracture toughness of bone. In the present study, we used a reconstructed synthetic mineral-OPN-mineral interface, and a biogenic (natural tooth dentin) mineral/collagen-OPN-mineral/collagen interface, to measure the fracture toughness of OPN on mineralized substrates. We used this system to test the hypothesis that OPN crosslinking by the enzyme tissue transglutaminase 2 (TG2) that is found in bone enhances interfacial adhesion to increase the fracture toughness of bone. For this, we prepared double-cantilever beam substrates of synthetic pure hydroxyapatite mineral, and of narwhal dentin, and directly apposed them to one another under different intervening OPN/crosslinking conditions, and fracture toughness was tested using a miniaturized loading stage. The work-of-fracture of the OPN interface was measured for different OPN formulations (monomer vs. polymer), crosslinking states, and substrate composition. Noncrosslinked OPN provided negligible adhesion on pure hydroxyapatite, whereas OPN crosslinking (by the chemical crosslinker glutaraldehyde, and TG2 enzyme) provided strong interfacial adhesion for both hydroxyapatite and dentin using monomeric and polymeric OPN. Pre-coating of the substrate beams with monomeric OPN further improved the adhesive performance of the samples, likely by allowing effective binding of this nascent OPN form to mineral/matrix components, with this pre-attachment providing a protein layer for additional crosslinking between the substrates.

Abstract
OBJECTIVES Chronic pain is prevalent, burdensome, and costly, and there are ethnic and racial disparities in treatment. Acupuncture is effective and safe, but access is limited. Group acupuncture can decrease cost and increase capacity by decreasing clinic space needs and increasing patient volume per acupuncturist; however, the effectiveness and patient acceptability of group and individual session acupuncture have never been directly compared. DESIGN The Acupuncture Approaches to Decrease Disparities in Pain Treatment (AADDOPT-2) study is a randomized comparative effectiveness trial of acupuncture for chronic pain. Semistructured in-depth interviews were conducted with a subset of patients enrolled in the trial. SETTINGS/LOCATION Outpatient clinics in an urban, low income area serving a primarily black and Hispanic population. SUBJECTS Qualitative interviews were conducted with 46 patients; 23 in each arm of the AADDOPT-2 study. INTERVENTIONS Patients were randomized to receive either individual acupuncture or acupuncture delivered in a small group. OUTCOME MEASURES Transcripts of the interviews were analyzed using an inductive thematic framework to explore and compare the patient experience in group and individual settings. RESULTS Patients in both study arms valued the pain relief, improved quality of life, and relaxation experienced during acupuncture. Privacy and mixed-sex groups were cited as a concern by a minority of patients; however, most of those randomized to the group setting noted that these concerns abated after initiating treatment. Differences between arms included the depth of the relationship with the acupuncturist and misgivings related to the treatment space. Group dynamics varied; some groups fostered a supportive, therapeutic interaction, while others were more reserved. CONCLUSIONS Patients in both arms valued their acupuncture experience. Participants described both positive and negative aspects of the group setting.

Abstract
X-linked hypophosphatemia (XLH) is a skeletal disease caused by inactivating mutations in the PHEX gene. Mutated or absent PHEX protein/enzyme leads to a decreased serum phosphate level, which cause mineralization defects in the skeleton and teeth (osteomalacia/odontomalacia). It is not yet altogether clear whether these manifestations are caused solely by insufficient circulating phosphate availability for mineralization or also by a direct, local intrinsic effect caused by impaired PHEX activity. Here, we evaluated the local role of PHEX in a 3-dimensional model of extracellular matrix (ECM) mineralization. Dense collagen hydrogels were seeded either with human dental pulp cells from patients with characterized PHEX mutations or with sex- and age-matched healthy controls and cultured up to 24 d using osteogenic medium with standard phosphate concentration. Calcium quantification, micro-computed tomography, and histology with von Kossa staining for mineral showed significantly lower mineralization in XLH cell-seeded scaffolds, using nonparametric statistical tests. While apatitic mineralization was observed along collagen fibrils by electron microscopy in both groups, Raman microspectrometry indicated that XLH cells harboring the PHEX mutation produced less mineralized scaffolds having impaired mineral quality with less carbonate substitution and lower crystallinity. In the XLH cultures, immunoblotting revealed more abundant osteopontin (OPN), dentin matrix protein 1 (DMP1), and matrix extracellular phosphoglycoprotein (MEPE) than controls, as well as the presence of fragments of these proteins not found in controls, suggesting a role for PHEX in SIBLING protein degradation. Immunohistochemistry revealed altered OPN and DMP1 associated with an increased alkaline phosphatase staining in the XLH cultures. These results are consistent with impaired PHEX activity having local ECM effects in XLH. Future treatments for XLH should target both systemic and local manifestations.

Abstract
BACKGROUND/AIMS Cancer clinical trials give patients access to state-of-the-art treatments and facilitate the translation of findings into mainstream clinical care. However, patients from racial and ethnic minority groups remain underrepresented in clinical trials. Primary care physicians are a trusted source of information for patients, yet their role in decision-making about cancer treatment and referrals to trial participation has received little attention. The aim of this study was to determine physicians' knowledge, attitudes, and beliefs about cancer clinical trials, their experience with trials, and their interest in appropriate training about trials. METHODS A total of 613 physicians in the New York City area primarily serving patients from ethnic and racial minority groups were invited via email to participate in a 20-min online survey. Physicians were asked about their patient population, trial knowledge and attitudes, interest in training, and personal demographics. Using calculated scale variables, we used descriptive statistical analyses to better understand physicians' knowledge, attitudes, and beliefs about trials. RESULTS A total of 127 physicians completed the survey. Overall, they had low knowledge about and little experience with trials. However, they generally had positive attitudes toward trials, with 41.4% indicating a strong interest in learning more about their role in trials, and 35.7% indicating that they might be interested. Results suggest that Black and Latino physicians and those with more positive attitudes and beliefs were more likely to be interested in future training opportunities. CONCLUSION Primary care physicians may be an important group to target in trying to improve cancer clinical trial participation among minority patients. Future work should explore methods of educational intervention for such interested providers.

Abstract
BACKGROUND Racial/ethnic minority groups remain underrepresented in clinical trials. Many strategies to increase minority recruitment focus on minority communities and emphasize common diseases such as hypertension. Scant literature focuses on minority recruitment to trials of less common conditions, often conducted in specialty clinics and dependent on physician referrals. We identified trust/mistrust of specialist physician investigators and institutions conducting medical research and consequent participant reluctance to participate in clinical trials as key-shared barriers across racial/ethnic groups. We developed a trust-based continuous quality improvement intervention to build trust between specialist physician investigators and community minority-serving physicians and ultimately potential trial participants. To avoid the inherent biases of non-randomized studies, we evaluated the intervention in the national Randomized Recruitment Intervention Trial (RECRUIT). This report presents the design of RECRUIT. Specialty clinic follow-up continues through April 2017. METHODS We hypothesized that specialist physician investigators and coordinators trained in the trust-based continuous quality improvement intervention would enroll a greater proportion of minority participants in their specialty clinics than specialist physician investigators in control specialty clinics. Specialty clinic was the unit of randomization. Using continuous quality improvement, the specialist physician investigators and coordinators tailored recruitment approaches to their specialty clinic characteristics and populations. Primary analyses were adjusted for clustering by specialty clinic within parent trial and matching covariates. RESULTS RECRUIT was implemented in four multi-site clinical trials (parent trials) supported by three National Institutes of Health institutes and included 50 associated specialty clinics from these parent trials. Using current data, we have 88% power or greater to detect a 0.15 or greater difference from the currently observed control proportion adjusting for clustering. We detected no differences in baseline matching criteria between intervention and control specialty clinics (all p values > 0.17). CONCLUSION RECRUIT was the first multi-site randomized control trial to examine the effectiveness of a trust-based continuous quality improvement intervention to increase minority recruitment into clinical trials. RECRUIT's innovations included its focus on building trust between specialist investigators and minority-serving physicians, the use of continuous quality improvement to tailor the intervention to each specialty clinic's specific racial/ethnic populations and barriers to minority recruitment, and the use of specialty clinics from more than one parent multi-site trial to increase generalizability. The effectiveness of the RECRUIT intervention will be determined after the completion of trial data collection and planned analyses.

Abstract
AIMS One method of femoral head preservation following avascular necrosis (AVN) is core decompression and insertion of a tantalum rod. However, there may be a high failure rate associated with this procedure. The purpose of this study was to document the clinical and radiological outcomes following total hip arthroplasty (THA) subsequent to failed tantalum rod insertion. PATIENTS AND METHODS A total of 37 failed tantalum rods requiring total hip arthroplasty were identified from a prospective database. There were 21 hips in 21 patients (12 men and nine women, mean age 37 years, 18 to 53) meeting minimum two year clinical and radiographic follow-up whose THAs were carried out between November 2002 and April 2013 (mean time between tantalum rod implantation and conversion to a THA was 26 months, 6 to 72). These were matched by age and gender to individuals (12 men, nine women, mean age 40 years, 18 to 58) receiving THA for AVN without prior tantalum rod insertion. RESULTS There were no functional outcome differences between the two groups. Tantalum residue was identified on all post-operative radiographs in the tantalum group. Linear wear rates were comparable between groups with no evidence of catastrophic wear in either group. CONCLUSION In the short term, tantalum rod implantation does not demonstrate an adverse effect on subsequent total joint replacement surgery. There is however, a high rate of retained tantalum debris on post-operative radiographs and thus there is an unknown risk of accelerated articular wear necessitating longer term study.

Abstract
Transglutaminase 2 (TG2), a protein-crosslinking enzyme, participates in extracellular matrix maturation and cell adhesion in cartilage and bone. We hypothesized that TG2 has similar roles in teeth. A TG activity assay and immunoblotting of rat tooth extracts showed TG activity and the presence of high-molecular-weight forms of the SIBLING (Small Integrin-Binding LIgand N-linked Glycoprotein) proteins: dentin matrix protein 1 (DMP1), dentin phosphoprotein (DPP), and bone sialoprotein (BSP). DMP1 and BSP, each containing both glutamine and lysine residues critical for crosslink formation, readily formed polymers in vitro when incubated with TG2. The ability of glutamine-lacking DPP to form polymers in vitro and in vivo demonstrates that it could act as a lysine donor for crosslinking, potentially having protein crosslinking partner(s) in teeth. Consistent with a role in cell adhesion, the TG2 isoform was co-localized by immunohistochemistry with its substrates at cell-matrix adhesion sites, including along odontoblast tubules (DMP1 and DPP), in the pericellular matrix of cementocytes (DMP1), and in predentin (BSP).

Abstract
INTRODUCTION Sleep disorders affect up to 1 in 4 adults and can adversely affect a variety of health conditions. However, little is known about detection of sleep disorders in ethnically diverse urban primary care settings. METHODS Patients in urban primary care settings completed surveys to screen for sleep problems and identify comorbid conditions. Providers were given screening results, and provided feedback regarding their clinical utility. RESULTS Participants (n = 95) were predominantly women (76.8%) and black, non-Hispanic (46.3%), or Hispanic (38.9%). High proportion of participants screened positive for insomnia (31.6%) and screened high risk for sleep apnea (42.1%). Only one-third (32.6%) of participants reported sleeping the recommended 7 to 9 hours per night. The presence of chronic pain (χ(2) = 4.97, P = .03) was associated with clinically significant insomnia. Obesity was associated with fewer hours of sleep per night, t = 2.19(87), P = .03, and risk for sleep apnea (OR = 3.11, 95% CI = 1.28-7.50). Participants were interested in receiving help for sleep issues during their primary care visits (40%), and providers found the screening at least somewhat useful (74.4%). DISCUSSION Results highlight the potentially high unmet need for screening and treatment of sleep problems in ethnically diverse urban primary care settings.

Abstract
Certain mutations in the COL1A1 and COL1A2 genes produce clinical symptoms of both osteogenesis imperfecta (OI) and Ehlers-Danlos syndrome (EDS) that include abnormal craniofacial growth, dental malocclusion, and dentinogenesis imperfecta. A mouse model (Col1a1(Jrt)/+) was recently developed that had a skeletal phenotype and other features consistent with moderate-to-severe OI and also with EDS. The craniofacial phenotype of 4- and 20-wk-old Col1a1(Jrt)/+ mice and wild-type littermates was assessed by micro-computed tomography (µCT) and morphometry. Teeth and the periodontal ligament compartment were analyzed by µCT, light microscopy/histomorphometry, and electron microscopy. Over time, at 20 wk, Col1a1(Jrt)/+ mice developed smaller heads, a shortened anterior cranial base, class III occlusion, and a mandibular side shift with shorter morphology in the masticatory region (maxilla and mandible). Col1a1(Jrt)/+ mice also had changes in the periodontal compartment and abnormalities in the dentin matrix and mineralization. These findings validate Col1a1(Jrt)/+ mice as a model for OI and EDS in humans.

Abstract
Background Integrative medicine (IM) provides patient-centered care and addresses the full range of physical, emotional, mental, social, spiritual, and environmental influences that affect a person’s health. IM is a “whole systems” approach that employs multiple modalities as opposed to an isolated complementary therapy. Thus, studying outcomes of IM is more challenging than evaluating an isolated intervention. Practice-based research networks (PBRNs) allow for clinicians/investigators at multiple diverse sites using common methodology to pool their data, increase participant sample size and increase generalizability of results. To conduct real-world, practice-based research, the Bravewell Collaborative founded BraveNet in 2007 as the first national integrative medicine PBRN. Methods and design Patients Receiving Integrative Medicine Effectiveness Registry (PRIMIER) is a prospective, non-randomized, observational evaluation conducted at fourteen clinical sites. Participants receive a non-standardized, personalized, multimodal IM approach for various medical conditions. Using the REDCap electronic platform, an anticipated 10,000 study participants will complete patient-reported outcome measures including Patient Reported Outcomes Measurement Information System (PROMIS)-29, Perceived Stress Scale-4, and the Patient Activation Measure at baseline, 2, 4, 6, 12, 18 and 24 months. Extractions from participants’ electronic health records include IM services received, as well as ICD diagnostic codes, and CPT billing codes associated with each IM visit. Repeated-measures analyses will be performed on data to assess change from baseline through 24 months with planned subgroup analyses to include specific clinical population and specific IM intervention or combinations. Discussion As the PRIMIER registry grows, we anticipate that our results would provide an indication of the promise of PBRN research efforts in IM. Analyses will incorporate a large sample of participants and an expected 10-year observation period and will provide the ability to evaluate the effect of IM on outcomes for specific clinical populations and specific IM interventions or combinations. As such, PRIMIER will serve as a national platform for future evaluations of IM best practices.

Abstract
OBJECTIVES To examine the experience of patients from a low-income, ethnically diverse medically underserved population receiving acupuncture for chronic pain. DESIGN Qualitative analysis using inductive thematic analysis of interviews with participants from an acupuncture trial. SETTINGS/LOCATION Four community health centers in the Bronx, New York. PARTICIPANTS Thirty-seven adults with chronic neck or back pain or osteoarthritis who participated in a previous acupuncture trial. INTERVENTIONS Up to 14 weekly acupuncture treatments. OUTCOME MEASURES Pain and quality of life were examined in the original trial; this study examines qualitative outcomes. RESULTS The themes grouped naturally into three domains of the acupuncture experience: the decision-making process, the treatment experience, and the effect of acupuncture on health. Regarding decision-making, important factors were a willingness to try something new even if you do not necessarily "believe" in it or have specifically positive expectations; a sense that medications were not working for their pain, that they also caused significant adverse effects, and that natural strategies might be preferable; and a feeling of desperation. Cost and access were significant barriers to acupuncture treatment. Regarding the process of acupuncture, the open and personal communication with the acupuncturist was an important factor, as were the sense that the process of acupuncture related to a natural process of healing or correction within the body and that part of making acupuncture successful required being open to the power of the mind to generate a positive outcome. Regarding the effect of treatment, notable aspects were the deep sense of rest and relaxation participants reported during treatment as well as the benefit they experienced for conditions other than pain. CONCLUSIONS The themes that emerged in this ethnically diverse, low-income population were very similar to those that have emerged over the past decade of qualitative research on the acupuncture experience in other patient populations.

Abstract
BACKGROUND The intrauterine device (IUD) is a highly effective contraceptive, yet not all primary care providers (PCPs) counsel adolescents about IUDs. We sought to describe PCPs' frequency of counseling adolescents about IUDs and identify whether different factors are associated with frequent counseling by pediatricians compared with family physicians and gynecologists. METHODS Surveyed PCPs affiliated with a Bronx, New York academic institution. MAIN OUTCOME Frequent counseling of female adolescents about IUDs. RESULTS Frequent counseling was lower in pediatricians compared with family physicians and gynecologists (35.8% and 81.6%, respectively, P < .001). Among all PCP types, frequent counseling was associated with feeling more competent counseling and managing expected IUD side effects (P < .001). Other significant variables included inserting IUDs themselves (P < .001, family physicians and gynecologists) or having access to an inserter in their office (P = .04, pediatricians). CONCLUSIONS Correlates of frequent IUD counseling differed according to PCP specialty. Our results suggest that interventions to increase IUD counseling should focus on improving PCPs' competency around counseling and side effect management as well as increasing access to IUD inserters.

Extracellular matrix mineralization in murine MC3T3-E1 osteoblast cultures: an ultrastructural, compositional and comparative analysis with mouse bone. Bone 2015; 71:244-56.

Abstract
Bone cell culture systems are essential tools for the study of the molecular mechanisms regulating extracellular matrix mineralization. MC3T3-E1 osteoblast cell cultures are the most commonly used in vitro model of bone matrix mineralization. Despite the widespread use of this cell line to study biomineralization, there is as yet no systematic characterization of the mineral phase produced in these cultures. Here we provide a comprehensive, multi-technique biophysical characterization of this cell culture mineral and extracellular matrix, and compare it to mouse bone and synthetic apatite mineral standards, to determine the suitability of MC3T3-E1 cultures for biomineralization studies. Elemental compositional analysis by energy-dispersive X-ray spectroscopy (EDS) showed calcium and phosphorus, and trace amounts of sodium and magnesium, in both biological samples. X-ray diffraction (XRD) on resin-embedded intact cultures demonstrated that similar to 1-month-old mouse bone, apatite crystals grew with preferential orientations along the (100), (101) and (111) mineral planes indicative of guided biogenic growth as opposed to dystrophic calcification. XRD of crystals isolated from the cultures revealed that the mineral phase was poorly crystalline hydroxyapatite with 10 to 20nm-sized nanocrystallites. Consistent with the XRD observations, electron diffraction patterns indicated that culture mineral had low crystallinity typical of biological apatites. Fourier-transform infrared spectroscopy (FTIR) confirmed apatitic carbonate and phosphate within the biological samples. With all techniques utilized, cell culture mineral and mouse bone mineral were remarkably similar. Scanning (SEM) and transmission (TEM) electron microscopy showed that the cultures had a dense fibrillar collagen matrix with small, 100nm-sized, collagen fibril-associated mineralization foci which coalesced to form larger mineral aggregates, and where mineralized sites showed the accumulation of the mineral-binding protein osteopontin. Light microscopy, confocal microscopy and three-dimensional reconstructions showed that some cells had dendritic processes and became embedded within the mineral in an osteocyte-like manner. In conclusion, we have documented characteristics of the mineral and matrix phases of MC3T3-E1 osteoblast cultures, and have determined that the structural and compositional properties of the mineral are highly similar to that of mouse bone.

A mixed-methods examination of communication between oncologists and primary care providers among primary care physicians in underserved communities. Cancer 2014; 121:908-15.

Abstract
BACKGROUND Research has demonstrated that communication and care coordination improve cancer patient outcomes. To improve communication and care coordination, it is important to understand primary care providers' (PCPs') perceptions of communication with oncologists as well as PCPs' communication needs. METHODS A mixed-methods approach was used in the present study. In the qualitative phase of the study, 18 PCPs practicing in underserved, minority communities were interviewed about their experiences communicating with oncologists. In the quantitative phase of the study, 128 PCPs completed an online survey about their preferences, experiences, and satisfaction with communication with oncologists. RESULTS Results indicated a PCP-oncologist gap in communication occurred between diagnosis and treatment. PCPs wanted more communication with oncologists, updates on their patients' prognosis throughout treatment, and to be contacted via telephone or email and saw their role as crucial in providing supportive care for their patients. CONCLUSIONS Although PCPs recognize that they play a critical, proactive role in supporting patients throughout the continuum of their cancer care experience, existing norms regarding postreferral engagement and oncologist-PCP communication often hinder activation of this role among PCPs. Expected standards regarding the method, frequency, and quality of postreferral communication should be jointly articulated and made accountable between PCPs and oncologists to help improve cancer patients' quality of care, particularly in minority communities.

Abstract
BACKGROUND AND OBJECTIVES Integrating family into family medicine has been recognized as important for the discipline, yet there is little known about how family-oriented care is taught in training environments. This paper presents results of a national survey assessing the status of teaching family concepts/skills in family medicine residency programs. METHODS We sought to survey the program director (PD), a behavioral science faculty (BSF), and a chief resident (CR) from all 454 Accreditation Council for Graduate Medical Education (ACGME) family medicine residency programs. RESULTS Respondents (n=489) were PDs (29%), CRs (34%), and BSF (36%). Of all respondents, 47% to 66% believe that integrating family concepts/skills into family medicine training is very important (highest level of importance). However, only 19%--23% believe their own programs place this level of importance on this curricular area. Less weight is given to family topics when compared with other behavior science subjects. Behavioral scientists who reported inclusion of (1) family concepts/skills in the formulation of ACGME competencies, (2) evaluation of residents on these skills, or (3) the presence of a family champion or scholar in the program, all reported teaching significantly more family-oriented skills compared to those that did not, respectively, 1 (6.96 versus 4.48), 2 (6.55 versus 4.97), and 3 (6.62 versus 4.54). CONCLUSIONS Teaching about the family in family medicine continues to be highly valued among educators and their trainees; however, it is not perceived to be similarly valued in residency programs. Current changes in health care offer opportunities to promote and affirm family-oriented care. New curricular strategies are needed so that family-oriented care continues to define the uniqueness of family medicine.

Abstract
Phosphatases are involved in bone and tooth mineralization, but their mechanisms of action are not completely understood. Tissue-nonspecific alkaline phosphatase (TNAP, ALPL) regulates inhibitory extracellular pyrophosphate through its pyrophosphatase activity to control mineral propagation in the matrix; mice without TNAP lack acellular cementum, and have mineralization defects in dentin, enamel, and bone. PHOSPHO1 is a phosphatase found within membrane-bounded matrix vesicles in mineralized tissues, and double ablation of Alpl and Phospho1 in mice leads to a complete absence of skeletal mineralization. Here, we describe mineralization abnormalities in the teeth of Phospho1(-/-) mice, and in compound knockout mice lacking Phospho1 and one allele of Alpl (Phospho1(-/-);Alpl(+/-) ). In wild-type mice, PHOSPHO1 and TNAP co-localized to odontoblasts at early stages of dentinogenesis, coincident with the early mineralization of mantle dentin. In Phospho1 knockout mice, radiography, micro-computed tomography, histology, and transmission electron microscopy all demonstrated mineralization abnormalities of incisor dentin, with the most remarkable findings being reduced overall mineralization coincident with decreased matrix vesicle mineralization in the Phospho1(-/-) mice, and the almost complete absence of matrix vesicles in the Phospho1(-/-);Alpl(+/-) mice, whose incisors showed a further reduction in mineralization. Results from this study support prominent non-redundant roles for both PHOSPHO1 and TNAP in dentin mineralization.

Abstract
Latissimus dorsi tendon transfer (LDTT) is technically challenging. In order to clarify the local structural anatomy, we undertook a morphometric study using six complete cadavers (12 shoulders). Measurements were made from the tendon to the nearby neurovascular structures with the arm in two positions: flexed and internally rotated, and adducted in neutral rotation. The tendon was then transferred and measurements were taken from the edge of the tendon to a reference point on the humeral head in order to assess the effect of a novel two-stage release on the excursion of the tendon. With the shoulder flexed and internally rotated, the mean distances between the superior tendon edge and the radial nerve, brachial artery, axillary nerve and posterior circumflex artery were 30 mm (26 to 34), 28 mm (17 to 39), 21 mm (12 to 28) and 15 mm (10 to 21), respectively. The mean distance between the inferior tendon edge and the radial nerve, brachial artery and profunda brachii artery was 18 mm (8 to 27), 22 mm (15 to 32) and 14 mm (7 to 21), respectively. Moving the arm to a neutral position reduced these distances. A mean of 15 mm (8 to 21) was gained from a standard soft-tissue release, and 32 mm (20 to 45) from an extensile release. These figures help to define further the structural anatomy of this region and the potential for transfer of the latissimus dorsi tendon.

Abstract
While advances in biomineralization have been made in recent years, unanswered questions persist on bone- and tooth-cell differentiation, on outside-in signaling from the extracellular matrix, and on the link between protein expression and mineral deposition. In the present study, we validate the use of a bioengineered three-dimensional (3D) dense collagen hydrogel scaffold as a cell-culture model to explore these questions. Dental pulp progenitor/stem cells from human exfoliated deciduous teeth (SHEDs) were seeded into an extracellular matrix-like collagen gel whose fibrillar density was increased through plastic compression. SHED viability, morphology, and metabolic activity, as well as scaffold mineralization, were investigated over 24 days in culture. Additionally, measurements of alkaline phosphatase enzymatic activity, together with immunoblotting for mineralized tissue cell markers ALPL (tissue-non-specific alkaline phosphatase), DMP1 (dentin matrix protein 1), and OPN (osteopontin), demonstrated osteo/odontogenic cell differentiation in the dense collagen scaffolds coincident with mineralization. Analyses of the mineral phase by electron microscopy, including electron diffraction and energy-dispersive x-ray spectroscopy, combined with Fourier-transform infrared spectroscopy and biochemical analyses, were consistent with the formation of apatitic mineral that was frequently aligned along collagen fibrils. In conclusion, use of a 3D dense collagen scaffold promoted SHED osteo/odontogenic cell differentiation and mineralization.

Abstract
PURPOSE Although the US adolescent pregnancy rate is high, use of the most effective reversible contraceptives-intrauterine devices (IUDs) and implantable contraception-is low. Increasing use of long-acting reversible contraception (LARC) could decrease adolescent pregnancy rates. We explored New York City primary care physicians' experiences, attitudes, and beliefs about counseling and provision of LARC to adolescents. METHODS We conducted in-depth telephone interviews with 28 family physicians, pediatricians, and obstetrician-gynecologists using an interview guide based on an implementation science theoretical framework. After an iterative coding and analytic process, findings were interpreted using the capability (knowledge and skills), opportunity (environmental factors), and motivation (attitudes and beliefs) conceptual model of behavior change. RESULTS Enablers to IUD counseling and provision include knowledge that nulliparous adolescents are appropriate IUD candidates (capability) and opportunity factors, such as (1) a clinical environment supportive of adolescent contraception, (2) IUD availability in clinic, and (3) the ability to insert IUDs or easy access to an someone who can. Factors enabling motivation include belief in the overall positive consequences of IUD use; this is particularly influenced by a physicians' perception of adolescents' risk of pregnancy and sexually transmitted disease. Physicians rarely counsel about implantable contraception because of knowledge gaps (capability) and limited access to the device (opportunity). CONCLUSION Knowledge, skills, clinical environment, and physician attitudes, all influence the likelihood a physician will counsel or insert LARC for adolescents. Interventions to increase adolescents' access to LARC in primary care must be tailored to individual clinical practice sites and practicing physicians, the methods must be made more affordable, and residency programs should offer up-to-date, evidence-based teaching.

Abstract
Tissue-nonspecific alkaline phosphatase (TNAP) is expressed in mineralizing tissues and functions to reduce pyrophosphate (PP(i) ), a potent inhibitor of mineralization. Loss of TNAP function causes hypophosphatasia (HPP), a heritable disorder marked by increased PP(i) , resulting in rickets and osteomalacia. Tooth root cementum defects are well described in both HPP patients and in Alpl(-/-) mice, a model for infantile HPP. In Alpl(-/-) mice, dentin mineralization is specifically delayed in the root; however, reports from human HPP patients are variable and inconsistent regarding dentin defects. In the current study, we aimed to define the molecular basis for changes in dentinogenesis observed in Alpl(-/-) mice. TNAP was found to be highly expressed by mature odontoblasts, and Alpl(-/-) molar and incisor roots featured defective dentin mineralization, ranging from a mild delay to severely disturbed root dentinogenesis. Lack of mantle dentin mineralization was associated with disordered and dysmorphic odontoblasts having disrupted expression of marker genes osteocalcin and dentin sialophosphoprotein. The formation of, initiation of mineralization within, and rupture of matrix vesicles in Alpl(-/-) dentin matrix was not affected. Osteopontin (OPN), an inhibitor of mineralization that contributes to the skeletal pathology in Alpl(-/-) mice, was present in the generally unmineralized Alpl(-/-) mantle dentin at ruptured mineralizing matrix vesicles, as detected by immunohistochemistry and by immunogold labeling. However, ablating the OPN-encoding Spp1 gene in Alpl(-/-) mice was insufficient to rescue the dentin mineralization defect. Administration of bioengineered mineral-targeting human TNAP (ENB-0040) to Alpl(-/-) mice corrected defective dentin mineralization in the molar roots. These studies reveal that TNAP participates in root dentin formation and confirm that reduction of PP(i) during dentinogenesis is necessary for odontoblast differentiation, dentin matrix secretion, and mineralization. Furthermore, these results elucidate developmental mechanisms underlying dentin pathology in HPP patients, and begin to explain the reported variability in the dentin/pulp complex pathology in these patients.

Abstract
OBJECTIVES We evaluated an intervention designed to identify patients at risk for hepatitis C virus (HCV) through a risk screener used by primary care providers. METHODS A clinical reminder sticker prompted physicians at 3 urban clinics to screen patients for 12 risk factors and order HCV testing if any risks were present. Risk factor data were collected from the sticker; demographic and testing data were extracted from electronic medical records. We used the t test, χ(2) test, and rank-sum test to compare patients who had and had not been screened and developed an analytic model to identify the incremental value of each element of the screener. RESULTS Among screened patients, 27.8% (n = 902) were identified as having at least 1 risk factor. Of screened patients with risk factors, 55.4% (n = 500) were tested for HCV. Our analysis showed that 7 elements (injection drug use, intranasal drug use, elevated alanine aminotransferase, transfusions before 1992, ≥ 20 lifetime sex partners, maternal HCV, existing liver disease) accounted for all HCV infections identified. CONCLUSIONS A brief risk screener with a paper-based clinical reminder was effective in increasing HCV testing in a primary care setting.
