A to E, Lateral views showing successive stages in the development of the otic vesicle into the membranous labyrinth from the fifth to eighth weeks. A to D, Diagrammatic sketches illustrating the development of a semicircular duct. F to I, Sections through the cochlear duct showing successive stages in the development of the spiral organ and the perilymphatic space from the 8th to the 20th weeks. Observe the relationship of these parts of the ear to the otic vesicle, the primordium of the internal ear. A, At 4 weeks, illustrating the relation of the otic vesicle to the pharyngeal apparatus. C, Later stage showing the tubotympanic recess (future tympanic cavity and mastoid antrum) beginning to envelop the ossicles. D, Final stage of ear development showing the relationship of the middle ear to the perilymphatic space and the external acoustic meatus. Note that the tympanic membrane develops from three germ layers: surface ectoderm, mesenchyme, and endoderm of the tubotympanic recess. Inductive influences from the otic vesicle stimulate the mesenchyme around the otic vesicle to condense and differentiate into a cartilaginous otic capsule (see. The transforming growth factor β1 may play a role in modulating epithelial-mesenchymal interaction in the internal ear and in directing the formation of the otic capsule. As the membranous labyrinth enlarges, vacuoles appear in the cartilaginous otic capsule and soon coalesce to form the perilymphatic space. The membranous labyrinth is now suspended in perilymph (fluid in perilymphatic space). The perilymphatic space related to the cochlear duct develops two divisions, the scala tympani and scala vestibuli (see. The cartilaginous otic capsule later ossifies to form the bony labyrinth of the internal ear. The internal ear reaches its adult size and shape by the middle of the fetal period (20-22 weeks). The proximal part of the tubotympanic recess forms the pharyngotympanic tube (auditory tube). It has been suggested that, in addition to apoptosis in the middle ear, an epithelium-type organizer located at the tip of the tubotympanic recess probably plays a role in the early development of the middle ear and tympanic membrane. The mastoid antrum is almost adult size at birth; however, no mastoid cells are present in newborn infants. By 2 years of age, the mastoid cells are well developed and produce conical projections of the temporal bones, the mastoid processes. Development of the External Ear page 433 page 434 the external acoustic meatus, the passage of the external ear leading to the tympanic membrane, develops from the dorsal part of the first pharyngeal groove. The ectodermal cells at the bottom of this funnel-shaped tube proliferate to form a solid epithelial plate, the meatal plug (see. Late in the fetal period, the central cells of this plug degenerate, forming a cavity that becomes the internal part of the external acoustic meatus (see. The external acoustic meatus, relatively short at birth, attains its adult length in approximately the ninth year. The primordium of the tympanic membrane is the first pharyngeal membrane, which forms the external surface of the tympanic membrane. In the embryo, the pharyngeal membrane separates the first pharyngeal groove from the first pharyngeal pouch (see. As development proceeds, mesenchyme grows between the two parts of the pharyngeal membrane and differentiates into the collagenic fibers in the tympanic membrane. To summarize, the tympanic membrane develops from three sources: Ectoderm of the first pharyngeal groove Endoderm of the tubotympanic recess, a derivative of the first pharyngeal pouch Mesenchyme of the first and second pharyngeal arches the auricle (pinna), which projects from the side of the head, develops from mesenchymal proliferations in the first and second pharyngeal arches-auricular hillocks-surrounding the first pharyngeal groove. As the mandible develops, the auricles assume their normal position at the side of the head (see. Note that three auricular hillocks are located on the first pharyngeal arch and three on the second arch. As the mandible and teeth develop, the auricles move from the superior neck region to the side of the head. The parts of the auricle derived from the first pharyngeal arch are supplied by its nerve, the mandibular branch of the trigeminal nerve; the parts derived from the second arch are supplied by cutaneous branches of the cervical plexus, especially the lesser occipital and greater auricular nerves. The facial nerve of the second pharyngeal arch has few cutaneous branches; some of its fibers contribute to the sensory innervation of the skin in the mastoid region and probably in small areas on both aspects of the auricle. Congenital Deafness page 434 page 435 Because formation of the internal ear is independent of development of the middle and external ears, congenital impairment of hearing may be the result of maldevelopment of the sound-conducting apparatus of the middle and external ears or of the neurosensory structures of the internal ear. Approximately three in every 1000 newborns have significant hearing loss, of which there are many subtypes. Most types of congenital deafness are caused by genetic factors, and many of the genes responsible have been identified. Congenital deafness may be associated with several other head and neck anomalies as a part of the first arch syndrome (see Chapter 9). Congenital fixation of the stapes results in conductive deafness in an otherwise normal ear. Failure of differentiation of the anular ligament, which attaches the base of the stapes to the oval window (fenestra vestibuli), results in fixation of the stapes to the bony labyrinth. This designation is made when the margin of the auricle or helix (arrow) meets the cranium at a level inferior to the horizontal plane through the corner of the eye. Almost any minor auricular defect may occasionally be found as a usual feature in a particular family. Minor anomalies of the auricles may serve as indicators of a specific pattern of congenital anomalies. For example, the auricles are often abnormal in shape and low-set in infants with chromosomal syndromes. Auricular Appendages Auricular appendages (skin tags) are common and may result from the development of accessory auricular hillocks. The appendages usually appear anterior to the auricle, more often unilaterally than bilaterally. The appendages, often with narrow pedicles, consist of skin but may contain some cartilage. Absence of the Auricle Anotia (absence of the auricle) is rare but is commonly associated with the first pharyngeal arch syndrome (see Chapter 9). Microtia Microtia (a small or rudimentary auricle) results from suppressed mesenchymal proliferation. This anomaly often serves as an indicator of associated anomalies, such as an atresia of the external acoustic meatus and middle ear anomalies. Preauricular Sinuses and Fistulas Pitlike cutaneous depressions or shallow sinuses are occasionally located in a triangular area anterior to the auricle. Preauricular sinuses may be associated with internal anomalies, such as deafness and kidney malformations. The embryologic basis of auricular sinuses is uncertain, but some are related to abnormal mesenchymal proliferation and defective closure of the dorsal part of the first pharyngeal groove. Most of this pharyngeal groove normally disappears as the external acoustic meatus forms. Other auricular sinuses appear to represent ectodermal folds that are sequestered during formation of the auricle. They are asymptomatic and have only minor cosmetic importance; however, they often develop serious infections. Auricular fistulas (narrow canals) connecting the preauricular skin with the tympanic cavity or the tonsillar sinus (fossa) (see. Usually the deep part of the meatus is open, but the superficial part is blocked by bone or fibrous tissue. Often abnormal development of both the first and second pharyngeal arches is involved. The auricle is also usually severely affected and anomalies of the middle and/or internal ear are sometimes present. Atresia of the external acoustic meatus can occur bilaterally or unilaterally and usually results from autosomal dominant inheritance. Absence of the External Acoustic Meatus Absence of the external acoustic meatus is rare; usually the auricle is normal. This anomaly results from failure of inward expansion of the first pharyngeal groove and failure of the meatal plug to disappear (see. Congenital Cholesteatoma this is a rest of epithelial cells (fragment of embryonic tissue that is retained after birth). The rest appears as a white cystlike structure medial to or within the tympanic membrane. The rest probably consists of cells from the meatal plug that were displaced during its canalization (see. Note the external orifice of the fistula below the auricle and the upward direction of the catheter (sinus tract) toward the external acoustic meatus. The groove deepens to form a hollow optic vesicle that projects from the forebrain. The optic vesicle contacts the surface ectoderm and induces development of the lens placode, the primordial lens. As the lens placode invaginates to form a lens pit and lens vesicle, the optic vesicle invaginates to form an optic cup. The retina, optic nerve fibers, muscles of the iris, and epithelium of the iris and ciliary body are derived from the neuroectoderm of the forebrain. The sphincter and dilator muscles of the iris develop from the ectoderm at the rim of the optic cup. The surface ectoderm gives rise to the lens and the epithelium of the lacrimal glands, eyelids, conjunctiva, and cornea. The mesenchyme gives rise to the eye muscles, except those of the iris, and to all connective and vascular tissues of the cornea, iris, ciliary body, choroid, and sclera. Defects of sight may result from infection of tissues and organs by certain microorganisms during the fetal period. Most ocular anomalies are caused by defective closure of the retinal fissure during the sixth week. Congenital cataract and glaucoma may result from intrauterine infections, but most congenital cataracts are inherited. The otic vesicle divides into a dorsal utricular part, which gives rise to the utricle, semicircular ducts, and endolymphatic duct, and a ventral saccular part, which gives rise to the saccule and cochlear duct. The bony labyrinth develops from the mesenchyme adjacent to the membranous labyrinth. The epithelium lining the tympanic cavity, mastoid antrum, and pharyngotympanic tube is derived from the endoderm of the tubotympanic recess, which develops from the first pharyngeal pouch. The auditory ossicles develop from the dorsal ends of the cartilages in the first two pharyngeal arches. The epithelium of the external acoustic meatus develops from the ectoderm of the first pharyngeal groove. The tympanic membrane is derived from three sources: endoderm of the first pharyngeal pouch, ectoderm of the first pharyngeal groove, and mesenchyme between the above layers. The auricle develops from the fusion of six auricular hillocks, which form from mesenchymal prominences around the margins of the first pharyngeal groove. Congenital deafness may result from abnormal development of the membranous labyrinth and/or bony labyrinth, as well as from abnormalities of the auditory ossicles. Recessive inheritance is the most common cause of congenital deafness, but a rubella virus infection near the end of the embryonic period is a major environmental factor known to cause abnormal development of the spiral organ and defective hearing. There are many minor anomalies of the auricle; however, some of them may alert the clinician to the possible presence of associated major anomalies. Low-set, severely malformed ears are often associated with chromosomal abnormalities, particularly trisomy 13 and trisomy 18. An infant has small, multiple calcifications in the brain, microcephaly, and microphthalmia. The eye was microphthalmic, and there was persistence of the distal end of the hyaloid artery. Mallo M: Formation of the middle ear: Recent progress on the developmental and molecular mechanisms. Maroon H, Walshe J, Mahmood R, et al: Fgf3 and Fgf8 are required together for formation of the otic placode and vesicle. At the external orifices, the digestive tract, for example, the mucous membrane and integument (Latin [L]. The skin consists of two layers that are derived from surface ectoderm and its underlying mesenchyme. The epidermis is a superficial epithelial tissue that is derived from surface ectoderm. The dermis is a deeper layer composed of dense, irregularly arranged connective tissue that is derived from mesenchyme. This meshwork of embryonic connective tissue or mesenchyme, derived from mesoderm, forms the connective tissues in the dermis.
Regimen-related diabetes distress was associated with greater interpersonal-related and burden-related diabetes distress cholesterol medication and constipation vytorin 30 mg free shipping, and depressive symptoms cholesterol medication generic buy 20mg vytorin amex, and worse adherence and HbA1c score cholesterol esc generic 20mg vytorin free shipping. Multiple regressions tested the unique role of regimen-related distress in adherence and HbA1c cholesterol chart for seafood purchase 30 mg vytorin with mastercard, above and beyond other types of diabetes distress and age cholesterol medication vytorin side effects order 30mg vytorin fast delivery. To examine diabetes cholesterol target values vytorin 20 mg, and not general distress, all analyses controlled for depressive symptoms. Regimen-related distress was uniquely related to both worse adherence and HbA1c, above and beyond other types of diabetes distress. Consistent with the literature, these results suggest that diabetes distress, particularly regimen distress, is associated with decreased adherence to self-management. Diabetes distress may be an important consideration for younger adult patients, who may struggle with competing life demands. Romantic partners can impact self-care behaviors and well-being by providing instrumental or emotional support when faced with a problem. Partners may also perceive diabetes as a shared issue and pool their resources in combating problems through a process of collaborative coping. Partners may also hinder self-care and well-being by avoiding diabetes problems or acting in a controlling manner. To examine the impact of partner behavior on well-being, we conducted a study involving 70 couples coping with recently diagnosed (<3 years) type 2 diabetes (61% white, M age = 54. Patients completed self-report measures of self-care, psychological and relational well-being, and partner behaviors (instrumental support, emotional support, communal coping, avoidance, and controlling behavior). Couples then participated in a videotaped discussion about a diabetes problem (which was later coded by independent observers for partner behaviors), after which they reported perceptions of the partner and discussion. Results indicated self-report and observational measures were related for some. Findings suggest partners play an important role in diabetes self-care and well-being. Adherence involves different factors that impede or promote self-care behaviors; a social learning approach offers an empirically supported mechanism through which to better understand cognitive, behavioral, and environmental barriers to diabetes adherence. The present study examined barriers to diabetes management among 64 participants (Mage = 52. Obstacles to medication adherence were encountered less than once per month (M = 1. Consistent with previous literature, depression was associated with an increased perception of barriers both overall (r = -. Gender, education, and race were unrelated to self-management obstacles; older age was associated with fewer perceived barriers to glucose testing (r = -. Complex behavior change, such as that required by diet and exercise regimens, seems most vulnerable to adherence barriers. Identifying and addressing such barriers through individualized intervention may allow for more effective and patient-centered care. Cross-sectional analyses for Y1 and for Y2 test relationships among temporally concurrent experience of the constructs. Specifically, a high internal health locus of control is associated with more diabetes self-care behaviors and lower A1C levels. The purpose of this study was to examine health protective behaviors, perceived susceptibility of developing type 2 diabetes, perceived severity of type 2 diabetes, and internal health locus of control among emerging adults with (n=66) or without a parent/ grandparent (n=131) diagnosed with type 2 diabetes. Participants completed a family history of type 2 diabetes form, the Summary of Diabetes Self-Care Activities Measure, the Behavioral Risk Factor Surveillance System sugary drinks subscale, risk of illness questions developed by Ranby (three items to assess perceived susceptibility of type 2 diabetes and one item to assess perceived severity of type 2 diabetes), and the Multidimensional Health Locus of Control Scales. Students with a familial risk for type 2 diabetes reported lower internal health locus of control scores (t(195) = 2. It can negatively impact quality of life, medication adherence, and clinical progression of the disease. Results: Significant differences in affect over time were found between the two conditions, with greater improvements in resistance exercise compared to the control (F=2. There were also significant differences in activation between the conditions over time (F=7. Compared to other racialethnic groups, persons of Hispanic origin are the most likely to die from diabetes. Comorbid depression is common in diabetes and contributes to poor health outcomes, but there is evidence that social support can mitigate these effects. Hispanics tend to have strong family ties that provide support, yet this support does not consistently lead to better outcomes. Thus, we examined the extent to which psychosocial factors and their effects on depression vary by gender and language-based acculturation. Methods: Using Pearson correlations and multiple regression, we examined cross-sectional, baseline associations of depression with perceived support, diabetes-related distress, and other social and personal factors obtained from principal components analysis. When adjusting for age, gender and language, psychosocial factors significantly associated with increased depression included less support received, greater emotional burden, and less ability to socialize or pursue normal activities. Conclusions: the social support provided by traditional family and social networks of less acculturated Hispanics may play an important role in lowering the risk of comorbid depression. The quality of interpersonal relationships and ability to continue normal activities may also play an important protective role. More acculturated women may be at greater risk for comorbid depression and interventions should seek to augment their support needs. Semi-structured qualitative interviews were conducted with 30 clients of the Linkage to Care intervention regarding their experiences with the intervention, and barriers and facilitators of medication adherence. Barriers to medication adherence included side effects, dislike of pills, housing instability, cost or insurance difficulties, and privacy concerns. Substance use was also a barrier for many participants, who indicated that they had been discouraged from taking medications while using substances, that substance use decreased their motivation to take medications, or led to forgetfulness. Facilitators to medication adherence included faith in an eventual cure as well as a "one pill" regimen. This medication regimen was highly attractive, especially for individuals who had previously been on more complicated previous regimens. Maintaining a "one pill" regimen also provided motivation for high adherence to avoid the need to switch regimens or add additional pills in the future. Interventions to increase adherence should include focus on the impact of substance use and abuse, and include informational and motivational content, as well as social support. No participants reported missing medication "because of being with a sexual partner". Results indicated that individual and structural barriers were the major factors associated with being lost to follow-up. A 14-item questionnaire asked to what extent participants rely on specific assumptions (He looks healthy, etc. Results: Participants were primarily White (94%) and welleducated (64% had completed college), and were similar between study arms. The sum of the attribution of serostatus questionnaire, measured by Likert scale, was significantly lower at the 3-month follow-up (M = 17. This reduction was maintained with the 3-month and 6-month responses not differing significantly [F(1, 38) = 0. Therefore, interventions have been developed to address both alcohol use and sexual risk behaviors. Independent raters coded participant, design and methodological characteristics, and intervention content. Results: the study samples included 9,551 participants (M=25 years of age; 38% women). Compared to controls, intervention participants reduced their sexual risk behaviors across a number of measures. There were no significant differences between the intervention and controls on any alcohol outcome with one exception: heavy drinking (d+=0. Future research should determine the optimal methods for integrating alcohol interventions with sexual risk reduction content. In path model analyses, controlling for age, race/ethnicity, sexual and gender identity, income, and relationship status, an indirect effect of comorbidities, through quality of life, was observed for all three outcomes. In other words, to the extent that comorbidities impair quality of life, outcomes such as depression, substance use problems, and medication adherence self-efficacy are also impacted. Accordingly, efforts to maximize improvements to quality of life and minimize the impact of comorbidities may yield improve mental and behavioral health outcomes among this already-burdened and underserved population. Participants completed a survey assessment utilizing Audio Computer Assisted Interviewing software. We sought to (a) characterize levels of intentional non-adherence and (b) examine demographic, health status, and attitudinal correlates of general adherence difficulties and adherence lapses that are patient initiated. Overall, 66% of participants reported at least one form of intentional non-adherence. Global adherence difficulties were associated with having higher daily pill counts, t (1,115) = -2. Participants/Method: Data collected from a sample of 743 Black and White students aged 18-24 were analyzed. Some groups seem to show improvement over time, while others experience poorer mental health, particularly depression, the longer they reside in the U. However, few studies have examined the relationships between place of birth and anti-depressant use in the U. Future studies should explore the influence of place of birth on anti-depressant use and mental healthcare treatment in the United States. Food insecurity was not associated with neurocognitive functioning for the control group. Mobile sensing platforms have potential to aid in recognizing symptoms of mental illness; however, early evidence of the potential value of this approach has not been clinically validated. Clinical symptoms were measured through validated structured clinical interview assessments (Structured Clinical Interview for Disorders) with a licensed clinical social worker. A combination hypothesis and data driven approach was used to derive the symptom models. The use of mobile sensing platforms to assess behavioral biomarkers can allow individuals, clinicians, and researchers to track episode onset, symptom progression, and relapse. While significant differences were found in rates of measurement across settings, overall rates were low. Asian-American populations are characterized by elevated suicide rates and a tendency to seek social support from family and friends over mental health professionals. Gatekeeper training programs have been developed to train frontline individuals in assisting an at-risk person to utilize mental health treatment resources. Methods: We adapted an evidence-based gatekeeper training into a two-hour, multi-modal and interactive event for JapaneseAmericans and related stakeholders. Then we evaluated the intervention compared to an attention control using mixed methods. Intervention participants (n=85) showed significant increases in all three types of intended gatekeeper behavior, all four measures of self-efficacy, and both measures of social norms relevant to suicide prevention, while the control group (n=48) showed no significant improvements. Additional results showed significantly higher satisfaction and no adverse experiences associated with the gatekeeper training. The separate collection of qualitative data, and integration with the quantitative survey constructs confirmed and expanded understanding about the benefits of the intervention. Conclusions: A brief, multimodal gatekeeper training is efficacious in promoting positive gatekeeper behaviors and self-efficacy for suicide prevention in an at-risk ethnic minority population of Japanese Americans. Participants were measured on percentage of days with missed doses for non-psychotropic medications. The majority of the sample was female (73%), AfricanAmerican (72%), and had a primary language of English (95%). Result: At baseline, participants have shown moderate to severe problem in maintaining QoL based on scoring standard of Skindex29 [overall 42.

Psychological well-being is a complex construct that has been conceptualized to include factors of (1) autonomy, (2) environmental mastery, (3) personal growth, (4) positive relation with others, (5) purpose if life, and (6) self-acceptance. One pathway that may operate as a link between marital status and these elements of psychological well-being may be effective couple communication and decision making. Frequent couple communication as well as joint decision-making may act as a pathway to increase psychological well-being in older individuals. The purpose of this study is to determine the factors related to suicidal ideation and suicide attempts among a statewide sample of college students. The 2013 Texas Survey of Substance Use among College Students (N=11,164; 60% female, 85% White) was a multi-stage cluster designed study, representing undergraduates ages 18 to 26 public and private universities, colleges, and community colleges across the state of Texas. Over six percent of students had thought about suicide in the past year and a little over one percent had attempted suicide in the past year. All variables except for parent education and past month alcohol use were correlated with either suicidal ideation or suicide attempt. Grade point average, skipping class, past month drug use, perceptions of suicide, underage drinking, and heavy drinking being problems on campus, depressive symptoms, and lifetime history of psychotropic medication were all associated with past year suicidal ideation in the regression model. However, the only variables related to past year suicide attempt were depressive and anxiety symptoms and the perception that suicide was a problem on campus. Very few factors were associated with past year suicide attempts, but both academic and behavioral factors were associated with past year suicidal ideation. Future efforts to reduce suicidality among college students should include campus-wide partnerships to identify those at highest risk. The purpose of this study was to (1) describe health behavior adoptions; (2) barriers to adoption; (3) support needed in order to engage in health behaviors; (4) and health behaviors adoptions desired among Latino caregivers. Interviews were conducted in English and Spanish about the caregiver role, family and social support, and health behaviors.

Binary systems for inducible regulation of transgene expression are widely used in mice. Methods: We developed a single, polycistronic tetracycline-inducible expression platform to control the expression of multiple cistrons in mammalian cells. This platform has three basic constructs: regulator, responder, and destination vectors. The modular Gateway recombineering-compatible components facilitate rapidly generating vectors to genetically modify mammalian cells. Results: We show that our combined expression construct drives expression of both the mCherry and Rs1 transgenes in a doxycycline-dependent manner. Heterozygous mice carrying the Rs1 expression construct showed normal growth and weight, and developed small increases in bone formation that could be observed in the calvaria. These findings indicate that promoter selection is an important factor when developing transgene expression models. This is an open access article distributed under the terms of the Creative Commons Attribution License creativecommons. They have proven valuable for studying the roles of activated G-protein signaling in complex systems, including cardiomyocyte function [4], neurological development and function [5-7], and bone development [8-11]. Various methods are available for introducing the responder and regulator constructs independently (for example, by mixing lentiviral constructs or sequential transgene introduction). These methods have significant limitations: the exact ratios of the responder and regulator plasmids are not fully controlled, the constructs may integrate at multiple sites (thus increasing the risk of off-target effects), and separate drug resistance genes may be needed to ensure that both constructs are maintained as stable integrants. To address these challenges and determine if global Gs signaling affects early mouse development, we developed a single-vector polycistronic Tet-inducible expression platform based on a modular construction strategy. This platform uses three vectors that can be recombined to form a single Tet-inducible expression vector. Materials and methods Plasmids All plasmid constructs used in this study, their Addgene accession numbers, and maps are summarized in Table S1 in Additional File 1 and Figures S1A-H in Additional File 2. The pA sequence from pDest27 (Invitrogen) was then cloned into the NotI/SbfI sites, again in reverse orientation. A LoxP site was introduced into the NdeI/XhoI sites, allowing full excision of the targeted construct when used together with the LoxP site in the pEntl1L3 vector. The self-cleaving 2A site generates two separate peptides in equal concentrations [26,27] via a ribosomal "skip" mechanism just before the C-terminal end of the 2A peptide [28] and has been useful for making multicistronic reporters [29]. However, the shortened TetO retained comparable function to the full-length TetO (designated with "fl" for full length) in separate in vitro assays (data not shown). The recombineering junctions within the final expression vectors were verified by sequencing. Medium was supplemented with 1 ng/ml doxycycline (a tetracycline analog) (Sigma Aldrich). Both males and females were analyzed together in our experiments as no sex-dependent differences were observed. Taqman probe sets used for expression analysis for apoptosis, pluripotency, and differentiation markers are as follows: Bad (Mm00432042 m1), Ccnb3 (Mm00805476 m1), Mcl1 (Mm01257352 g1), Oct3/4 (Mm00658129 gH) and Sox2 (Mm00488369 s1), Foxa2 (Mm01976556 s1), Nestin (Mm00450205 m1), Nkx2. Results Assembly of single-vector poly-cistronic Tet-regulated expression vectors To create a single-vector Tet-regulated expression construct, we used a modular cloning strategy employing the Gateway recombineering system [37] with standardized entry vector plasmids to assemble the tetracyclineregulated components into different destination vector backbones (Figure 1A). The mCherry and Rs1 cistrons are separated by a P2A ribosomal skip sequence to allow simultaneous expression of both peptides. The entry plasmids were recombined using Gateway technology into the desired destination vector containing the AttR1 and AttR2 Gateway sites. In addition, flanking insulator sequences are included to minimize any read-through activation of the constructs by surrounding promoters (such as Rosa26) that may lead to "leakiness" or steric interference from endogenous promoter activity. The destination vector contains the recipient attR1 and attR2 sites, as well as a selectable marker, and serves as the final backbone for expressing the transgenes in mammalian cells. Multiple Gateway destination vectors based on standard expression plasmids, lentiviral expression vectors, and knockin constructs are now generally available. We combined the regulator, responder, and destination vectors by Gateway recombineering to create the final single-vector Tet-inducible expression constructs. The regulator and responder cassettes were designed to lie in opposite orientations with the polyA tails nearest each other, thus preventing cross-activation and transcriptional read-through. The unidirectional three-way Gateway recombination strategy ensures that the regulator and responder cassettes are always positioned in the proper orientation. In addition, insulator sequences from the chicken b-globin gene flank both sides of the construct to prevent inadvertent read-through into the expression cassettes. Finally, we placed flanking LoxP sites around the construct to allow for Cre-mediated TetO LoxP Ins mCh-Rs1 pA AttB3 AttB2 Wildtype Targeted Un-targeted Hsiao et al. The Rs1 and mCherry cistrons are separated by a P2A ribosomal skip sequence, which allows genes to be expressed simultaneously from the same promoter [28]. The 2A sequences have also been used to express peptides in equimolar ratios [26,27]. Cells cultured in the presence of doxycycline, thus suppressing the transactivator activity, showed no mCherry expression after 24 hours (Figure 1B). In contrast, cells cultured in the absence of doxycycline showed robust mCherry expression (Figure 1C), indicating doxycyclinedependent suppression of transgene expression from our expression construct. Site-specific introduction of the expression cassette into the transcriptionally-permissive Rosa26 locus was performed by gene targeting into E14Tg2A. Fourteen highpercentage chimeras were identified, and two lines (Line A and Line B) were backcrossed onto the C57Bl/6 background. Mice were maintained and mated on doxycyclinecontaining chow to suppress transgene expression and minimize any risk of embryonic lethality, as has been hypothesized to occur in diseases with activated Gs signaling during embryogenesis such as McCune-Albright Syndrome [44]. Surprisingly, only whole bone showed an induction of Rs1 expression in mice raised off of doxycycline (Figure 3). Rs1 expression was allowed (off doxy) or suppressed (on doxy) in mice for four weeks starting from gestation. To determine if the TetO-mCh-Rs1 responder portion of the construct containing a P2A ribosomal skip sequence was functional, we generated ColI(2. At nine weeks of age, the double mutants showed a significant increase in bone mineral density (Figure 4A) that was comparable to our published results in the ColI(2. Our results also show that the Rs1 and mCherry cistrons can be expressed from a single locus when separated by a P2A sequence, and that the Rs1 receptor expressed in this manner retains biological activity in vivo. Discussion We created a modular system that uses Gateway recombineering technology to combine the binarytetracyclineregulated expression components into a single vector. By using a targeting vector with a known genomic insertion site (Rosa26), we could introduce all of the components needed for tetracycline-regulated expression into a wellcharacterized and transcriptionally-active locus. Although a variety of methods for combining the tetracycline-inducible expression components into a single vector have been described [14-22,46,47], our modular system has the added advantage of facilitating the rapid interchange of the expression components for tetracycline-induced expression as well as the choice of viral and non-viral delivery backbones. We easily inserted the expression cassettes into two final destination vectors, including a new Gateway-enabled construct for targeting into the mouse Rosa26 locus. The observed low levels of Rs1 expression in mouse tissues likely accounts for the absence of embryonic lethality and other pathology we would have expected if our model mimicked McCune-Albright syndrome [44]. This system could be used for a variety of genetic studies where a single cassette is advantageous. To facilitate these applications, we generated a series of improved vectors (Table S2 in Additional File 3 and Figures S2A-F in Additional File 4). We believe that these constructs will help advance the generation of new inducible expression models. In addition, these constructs are compatible with new technologies such as transposon-mediated gene Hsiao et al. The modular design allows rapid introduction of different combinations of promoters and expressed transgenes. These findings indicate that the specific choice of the promoter is an important consideration for driving high expression of the transgenes and that promoters validated for use in tissue culture models may have different functional characteristics when used in vivo.

This study assessed State policy from the broadest perspective: prevention, intervention, identification, and treatment of prenatal substance exposure, including immediate and ongoing services for the infant, the mother, and the family. States have responded in different ways to mounting concerns over the negative effects that prenatal exposure to illicit drugs and alcohol have on developing infants. States have instituted a range of policies to address prenatal substance exposure. These policies are carried out by multiple agencies and organizations, and practice does not always conform to official policy. This need makes the issue of developing system linkages as important as the issue of handling each of the five intervention points, since the linkages pull the interventions in the five areas together. Information was gathered and analyzed from three sources: a review of Federal policies and actions; a review of existing literature and summaries of State policies; and structured interviews with key informants in 10 States. States were included from different regions of the Nation and of different sizes to provide a useful sample. The States selected were California, Hawaii, Illinois, Maryland, Massachusetts, Minnesota, Rhode Island, South Carolina, Virginia, and Washington. The typical informants were officials in State agencies responsible for child welfare, maternal and child health, and drug and alcohol treatment. Other contacts included staff from family or dependency courts, developmental disabilities agencies, and hospitals. An interview guide was drafted based on the primary policy questions to be assessed. Pilot test interviews were conducted with two States, and final revisions to the interview guide were then made. A content analysis emphasizing the fivepoint framework was conducted on the qualitative interview data. Additional documentation, such as State legislation, administrative guidelines, and practice protocols, was compiled from the States based on information provided in the interviews. During the data collection phase, information was reviewed and contacts were made with additional States, including Arkansas, Colorado, Maine, and Texas. News reports on the current legislative proposals in these States were collected, reviewed, and summarized for inclusion in this report as additional detail. Pre-Pregnancy Awareness Nineteen of the States have public education campaigns that emphasize the harm done by using alcohol, tobacco, and illicit drugs during pregnancy. Some States also have worked with institutions of higher education to disseminate this message. However, the national rates of use during the first trimester suggest that the message is not getting through to many women before they are aware of their pregnancies, especially those who are younger. Good model programs for prenatal screening operate in most of the 10 States, but no service delivery system in the Nation requires prenatal screening for substance use. Although Medicaid covers the cost of 37% of births nationally, there is no Medicaid requirement for prenatal screening for substance use. Although several States have done onetime prevalence studies, no State has current prevalence data on substance use during pregnancy. Seven of the 10 States interviewed consider prenatal exposure to be evidence of child abuse or neglect, whereas three others do not. Because of the lack of uniformity in child welfarereferred developmental assessments used in most States, it is difficult to assess status in immediate postnatal services and the variability in State policy and practice is itself a finding. Services for Children and Families Ideally, services for the infant or child and the parents are woven together in a comprehensive approach. More typically, the primary emphasis is on the child or the parents, rather than on both simultaneously.

We examined the prevalence of chronic health conditions and their associations with depressive and anxiety symptoms from pre-adolescence to mid-adolescence in a community sample of preadolescents. Methods: this longitudinal study includes 5,147 youth and their caregivers from three U. Youth reported on their depressive symptoms at ages 11, 13, and 16 and their anxiety symptoms at ages 13 and 16. Participants with and without chronic health conditions were compared on depressive and anxiety symptoms at each time point using linear regression models, adjusting for demographic covariates and sampling design. Results: Nearly forty four percent of youth experienced a chronic health condition. The prevalence of chronic health conditions was higher in Non-Hispanic Whites and males. Having any type of chronic health condition was associated with a persistent elevation in depressive and anxiety symptoms. Experiencing multiple conditions put adolescents at even higher risk of elevated depressive and anxiety symptoms. Conclusions: Youth with chronic health conditions are at risk of experiencing more depressive and anxiety symptoms from preadolescence to mid-adolescence. Mental health should be monitored in children with chronic health conditions, especially as they transition into adolescence. Anxiety psychopathology occurs in approximately half of all epilepsy patients (Beyenberg et al. Indeed, anxiety is associated with greater seizure frequency and functional impairment (Choi-Kwon et al. However, there has been little exploration of the role of anxiety-related cognitive risk factors in epilepsy. Yet a large body of research has found that there is significant street-to-street variability in crime problems. Capturing these street-level variations in crime may therefore be important for understanding the relationships between violent crime and mental health. We compare hot spot streets (averaging more than 24 violent crime calls a year) with cool (x=6 violent crime calls) and cold spots (x=1. We find large and significant differences between hot spots and cool spots suggesting that mental health services should be specially directed at hot spot streets. First, we used propensity score matching to identify comparable samples of respondents from high crime and low crime areas. Second, we used negative binomial regression to assess the influence of street-level violent crime on mental illness, incorporating the propensity scores as weights in the regression model. Mindful behaviors and thoughts may account for the prevalence of higher resilience in this population, especially the act of observing without judgment. Using the Transactional Model of Stress and Coping (Lazarus & Cohen, 1977) as a theoretical framework, we hypothesize that negative social exchange (Test of Negative Social Exchange, Ruehlman & Karoly, 1991) and perceived stress (Perceived Stress Scale, Cohen & Kamarck, 1983) are negatively correlated with resilience (Connor-Davidson Resilience Scale, Connor et al. After providing informed consent and completing the survey, participants received a $25 incentive. A hierarchical regression analysis found our model to be significant overall (Adjusted R2=. Negative social exchange and perceived stress negatively correlate with resilience (=-. Resilience often protects against negative mental health outcomes often associated with discrimination and stigma-related stress (Meyer, 2015). No significant differences were found between groups in their self-reported depressive symptoms, selfesteem, and overall psychiatric symptoms. Prediabetes was defined by prior diagnosis of impaired fasting glucose or impaired glucose tolerance in the electronic medical record problem list or A1c between 5. This risk factor has been posited as one explanation to why women have higher rates of these mental health issues than men, despite also reporting higher rates of social support. The current study proposed that problem-solving, emotion coping, and different types of social support would interact with co-rumination in order to differentially predict depression and anxiety. Current stress level was predicted to also interact with co-rumination and coping variables to predict these outcomes. The sample consisted of 63 female undergraduate students, the majority who were 18 years old (M = 18), were freshmen in college (85%), and identified as Caucasian/White (67%). Participants completed measures of co-rumination, coping, stress, anxiety and depressive symptoms. Findings indicated that co-rumination, coping, and stress did not interact to predict depressive symptoms. The relationship between co-rumination and anxiety varied as a function of both appraisal support (=. These findings demonstrated that women who are more likely to engage in co-rumination had higher levels of anxiety. Nonetheless, for women who indicated they had higher levels of stress, co-rumination appeared to be protective against anxiety. The present findings highlight the need for more understanding in this area and especially further exploration of the role of co-rumination in anxiety and in young adult women. Determining the factors that make women vulnerable to depression and anxiety is important given the high rates of clinical diagnoses in this population. Future research should explore the interplay of co-rumination, stress and coping abilities using more diverse samples in order to expand our understanding of how risk for depression and anxiety is conferred in other populations. This study examines barriers faced by Taiwanese parents in taking their affected children to be tested. Such genomic-related health disparities should be addressed to attain health equity and for policy implications. This project further tested the benefits of these interviews for patients on inpatient medical units and the effects on patient satisfaction. We hypothesized that by telling stories about coping with previous adversity, patients would develop greater coping self-efficacy and report greater satisfaction with their hospital experience. Trained hospital volunteers conducted 45-60 minute interviews with patients during their inpatient stay (n=46; age=69. Interviews were audio recorded and reviewed by study personnel to provide interviewer feedback. Positive and negative affect and coping self-efficacy were measured pre- and post-interview, and patient satisfaction was assessed at discharge. Paired-sample t-tests compared positive affect, negative affect, and coping self-efficacy pre- and post-interview. Preliminary results suggest this intervention has a beneficial impact on positive affect and patient satisfaction during hospitalization. While this ongoing project requires further recruitment of patients to gather a control group and a more representative sample, these early results are promising. Complementary treatment options, such as mindfulness-based interventions, are important areas to explore. There was a significant indirect effect of trait mindfulness on depression through pain, b = -0. It also suggests that the relationship between mindfulness and depression is partially explained by pain and the relationship between mindfulness and pain is partially explained by depression. For example, the relationship between depression and lifetime substance use outcomes are mediated by negative urgency (Pang et al. To our knowledge, however, the impact of impulsivity on the relationship between depression and involvement in co-morbid risk behaviors has not been explored. Using a crosssectional sample of college students (N=778), we investigated relationships between impulsivity, depression, and number of risk behaviors. We classified participants as engaging in each risk behavior if they endorsed that others had complained about the behavior: 32. Bootstrapped mediation analyses (Preacher & Hayes, 2004) indicated the relationship between depression and multiple risk behaviors was partially mediated by negative urgency, positive urgency, lack of premeditation and perseverance, but not sensation seeking. The extent to which various forms of impulsivity can be modified to prevent involvement in multiple risk behaviors should be a focus of future research. Additionally, among the studies that have found an association between skin tone and health, very few have systematically investigated the mechanisms underlying the association. The goal of this study was two-fold: 1) to reconcile inconsistencies in previous findings; and 2) to explore multiple mechanisms through which skin tone may affect health in Black Americans. One hundred and eighteen self-identified Black Americans completed a series of measures, including physical/mental health as well as factors that may be associated with both skin tone and health. One likely reason for the previously mixed findings is the use of suboptimal techniques in past studies assessing skin tone. In the present study, we quantified skin tone by objectively assessing luminosity from participant faces using a spectrometer. Furthermore, a series of mediation analyses using bootstrapping technique provided preliminary results suggesting that the association between skin tone and mental health was mediated by both self-esteem and perceived discrimination independently, whereas the association between skin tone and physical health was mediated by selfesteem. These results offer further insight into the role of skin tone in within-race health disparities and may aid in the development of potential interventions as these mediators found in this study are relatively malleable psychological constructs. However, there has not been any study examining depressive symptoms across regions. The purpose of this study was to investigate the prevalence of the older population experiencing depressive symptoms across different regions in the United States. Methods Data were obtained from the 2011-2014 National Health and Aging Trends Study, a longitudinal study that included a nationally representative sample of individuals aged 65 or older. Regions of residence were categorized by Northeast, Midwest, South and West census regions. A composite score of 3 or greater from the Personal Health Questionnaire-2 was used to indicate the presence of depressive symptoms. The comparison of proportion having depression across regions were analyzed using chi-square tests. Results A total of 3,863 participants over the age of 65 were included in this study. Disparities in the prevalence of depressive symptoms were observed across different regions in the United States. Conclusion Understanding regional variations of depressive symptoms can inform the public regarding resource allocation and treatment models. Overall, the premotivational and social support variables accounted for 40% of the variance in intentions, with affective attitudes (=. Methods: Overweight adults (n=12) were recruited for a 4-week trial to examine the usability of the Bite Counter for dietary self-monitoring. Participants received behavior change information along with a bites/day goal, and used the counter to track their diet by measuring bites taken at each eating event. Items measuring the usability of the counter and information processing (user control, cognitive load, and novelty) were assessed on the final survey. Conclusions: Use of the Bite Counter was significantly associated with eating behavior conducive to weight management and increased self-efficacy in resisting overeating when in physical discomfort and doing positive activities. This is primarily due to the calorically dense, nutrition-poor offerings at these types of eating establishments. Furthermore, research shows that the majority of restaurant patrons base purchasing decisions on taste, price and habit, regardless of calorie or nutrient content. Methods: Customer receipts and survey data were collected from 329 participants using street-intercept survey methodology at 29 fast-food locations in low- and high-income neighborhoods throughout the Phoenix metropolitan area. Multivariate regression analyses examined the association between weight status and fast-food purchases. Conclusion: Food choices made at fast-food restaurants vary by patron weight status. Behavior interventions aimed at reducing caloric consumption at fast-food restaurants should target specific purchase behaviors such as choosing healthier sides, not ordering sides and promoting the use of calorie menu labels among customers, particularly those most at risk for poor health outcomes. However, little research has explored potential psychological mechanisms underlying incentive-induced behavior change and maintenance, and some theorists predict that incentives could undermine intrinsic motivation to engage in behavior. The present study employed a brief 3-arm randomized controlled trial to examine how incentive interventions affect psychological factors thought to underlie behavior maintenance. Behavior engagement and theoretically-informed psychological factors were measured at baseline, at the end of the intervention, and two weeks following the cessation of the intervention. In turn, these increases predicted behavior maintenance at follow-up (attitudes: t(55) = 2. In sum, this study demonstrates that monetary incentives can alter health behavior engagement without decrements in intrinsic motivation or other relevant cognitive and motivational constructs. Further, it suggests that incentives may serve as a mechanism by which to initiate behavior change but that increased experience with the behavior may then lead to enhancements in key psychological constructs, which can potentiate behavior maintenance following the cessation of incentives. These foods, containing artificial combinations of added sugar, fat, and/or salt, may enhance activation of brain reward circuitry, and may thus lead to preferential selection of these foods over more natural alternatives. This study examined associations of food reward sensitivity with eating behaviors. Participants selfreported weekly intake frequency of fast food and daily intake of 100% fruit juice, fruit, green vegetables, orange vegetables, beans, whole grains, soda (not diet), sweet/salty snacks, nuts/seeds, processed meats, fish, dairy products, and cheesy foods. In this nationallyrepresentative sample of young adults, food reward sensitivity was associated with greater intake of foods of minimal nutritional value, but was not associated with intake of more health-promoting foods, suggesting food reward sensitivity may lead to preferential intake of unhealthful foods. For consuming fruits and vegetables (F&V) at recommended levels, more people were in the pre-contemplation (36. For low fat diet adherence, the most people were in the pre-contemplative stage (38. Although few barriers to F&V consumption were reported, the most frequent was F&V being too expensive (35.
