RESUMEN

BACKGROUND: Burnout and psychosocial distress are serious and growing issues for healthcare workers (HCWs) and healthcare systems across the globe. Exacerbated by changes in healthcare delivery during and following the Covid-19 pandemic, these issues negatively affect HCW wellbeing, clinical outcomes and patient safety. Art Therapy has demonstrated promise as a suitable but under researched intervention, warranting further investigation. This systematic review aims to ascertain what art therapy-based interventions used to address burnout and / or psychosocial distress in HCWs have been reported in the health and social care literature and how these have been evaluated. METHODS: Six databases (PubMed, PsycINFO, MEDLINE, EMBASE, CINAHL, ProQuest Central), Google Scholar and three clinical trial registries (CENTRAL, ICTRP and ClinicalTrials.gov) were searched for studies using art therapy-based methods to engage with burnout risk or psychosocial distress in HCWs. Following screening for eligibility study characteristics and outcomes were extracted by two reviewers independently. Studies were evaluated using the Joanna Briggs Institute (JBI) Critical Appraisal Tools. Outcomes were grouped for analysis. Quantitative and qualitative results were synthesised and integrated using narrative synthesis. RESULTS: Twenty-seven studies, drawn from thirteen countries, spanning five continents were selected for inclusion. Fifty percent were published in the last five years, indicating growing global research in the field. Fourteen studies used quantitative research methods and thirteen used qualitative methods. A total of 1580 participants took part in the studies, with nurses most broadly represented (59%). Interventions were mostly delivered in groups (95%) and by an art therapist (70%). Heterogeneity and insufficient randomised controlled trials precluded the possibility of meta-analysis. However, a review of available data showed evidence of medium to large effects for emotional exhaustion (burnout), work-related stress and common mental health issues. A content analysis of qualitative data of perceived effect complemented quantitative findings. CONCLUSION: Global research into the use of art therapy-based methods to address burnout and psychosocial distress in HCWs is growing. Whilst further high-quality evidence such as randomised controlled trials would be beneficial, findings suggest that art therapy-based methods should be strongly considered as an acceptable and effective treatment for symptoms of emotional exhaustion (burnout) and psychosocial distress in HCWs.

RESUMEN

OBJECTIVE: Little is known about the extent to which interventions can prevent perinatal anxiety disorders. We conducted a systematic review and meta-analysis to examine whether interventions can decrease the onset and symptoms of perinatal anxiety among individuals without an anxiety disorder diagnosis. METHOD: We conducted a comprehensive literature search across five databases related to key concepts: (1) anxiety disorders/anxiety symptom severity (2) perinatal (3) interventions (4) prevention. We included studies that examined a perinatal population without an anxiety disorder diagnosis, included a comparator group, and assessed perinatal anxiety. We included interventions focused on perinatal anxiety as well as interventions to prevent perinatal depression or influence related outcomes (e.g., physical activity). RESULTS: Thirty-six studies were included. No study assessing the incidence of perinatal anxiety disorder (n = 4) found a significant effect of an intervention. Among studies assessing anxiety symptom severity and included in the quantitative analysis (n = 30), a meta-analysis suggested a small standardized mean difference of -0.31 (95% CI [-0.46, -0.16], p < .001) for anxiety at post intervention, favoring the intervention group. Both mindfulness (n = 6), and cognitive behavioral therapy approaches (n = 10) were effective. CONCLUSIONS: Interventions developed for perinatal anxiety were more effective than interventions to prevent perinatal depression. Psychological interventions show promise for reducing perinatal anxiety symptom severity, though interventions specifically targeting anxiety are needed.

RESUMEN

BACKGROUND: Arts therapies are widely but inconsistently provided in community mental health. Whilst they are appealing to patients, evidence for their effectiveness is mixed. Trials to date have been limited to one art-form or diagnosis. Patients may hold strong preferences for or against an art-form whilst group therapies rely on heterogeneity to provide a range of learning experiences. This study will test whether manualised group arts therapies (art therapy, dance movement therapy and music therapy) are effective in reducing psychological distress for diagnostically heterogeneous patients in community mental health compared to active group counselling control. METHODS: A pragmatic multi-centre 2-arm randomised controlled superiority trial with health economic evaluation and nested process evaluation. Adults aged ≥ 18, living in the community with a primary diagnosis of psychosis, mood, or anxiety disorder will be invited to participate and provide written informed consent. Participants are eligible if they score ≥ 1.65 on the Global Severity Index of the Brief Symptom Inventory. Those eligible will view videos of arts therapies and be asked for their preference. Participants are randomised to either their preferred type of group arts therapy or counselling. Groups will run twice per week in a community venue for 20 weeks. Our primary outcome is symptom distress at the end of intervention. Secondary outcomes include observer-rated symptoms, social situation and quality of life. Data will be collected at baseline, post-intervention and 6 and 12 months post-intervention. Outcome assessors and trial statisticians will be blinded. Analysis will be intention-to-treat. Economic evaluation will assess the cost-effectiveness of group arts therapies. A nested process evaluation will consist of treatment fidelity analysis, exploratory analysis of group process measures and qualitative interviews with participants and therapists. DISCUSSION: This will be the first trial to account for patient preferences and diagnostic heterogeneity in group arts therapies. As with all group therapies, there are a number of logistical challenges to which we have had to further adapt due to the COVID-19 pandemic. Overall, the study will provide evidence as to whether there is an additive benefit or not to the use of the arts in group therapy in community mental health care.

RESUMEN

BACKGROUND: Despite effective treatments, one fifth of patients develop chronic depression. Music therapy may offer a different approach. This study aimed to assess feasibility and acceptability of a music therapy intervention and trial methodology. METHODS: A parallel two-arm randomised controlled trial with wait-list control, mixed feasibility/acceptability measures and nested process evaluation. Adults with long-term depression (symptom duration > 1 year) were recruited from community mental health services and computer randomised to 42 sessions of group music therapy with songwriting three times per week or wait-list control. Depression, social functioning, distress, quality of life, satisfaction and service use were assessed by blinded researchers at enrolment, 1 week and 3 and 6 months post-therapy. Outcomes were analysed descriptively, controlling for baseline covariates. Recruitment (number eligible, participation and retention rates) and intervention (fidelity, adherence) feasibility were assessed using pre-defined stop-go criteria. Attendance, adverse events, mood, relationship satisfaction and semi-structured interviews were analysed in a nested process evaluation. RESULTS: Recruitment processes were feasible with 421 eligible, 12.7% participation and 60% (18/30) retention. Thirty participants were randomised to intervention (N = 20) and control (N = 10). Session attendance was low (mean 10.5) with four withdrawals. Music therapist adherence was good but changes to session frequency were suggested. Outcomes were available for 10/20 treatment and 9/10 wait-list participants. Depression increased in both arms post-therapy. Treatment depression scores fell below baseline 3 and 6 months post-therapy indicating improvement. Wait-list depression scores increased from baseline 3 and 6 months post-therapy. At 3 months, the treatment arm improved from baseline on all measures except satisfaction and functioning. At 6 months, quality of life, distress and functioning improved with reduction in health service contacts. High-attending participants improved more than low-attending. Seven adverse events (one serious) were reported. LIMITATIONS: As this was a feasibility study, clinical outcomes should be interpreted cautiously. CONCLUSION: A randomised controlled trial of group music therapy using songwriting is feasible with inclusion criteria and session frequency modifications, but further intervention development is required.

RESUMEN

Mild traumatic brain injury (mTBI) affects 42 to 56 million individuals worldwide annually. Even more individuals are affected by sub-concussive repetitive head impacts (SRHIs). Such injuries may result in significant acute and chronic symptoms. A study of how individuals may adjust or augment their nutritional and dietary habits to prevent cumulative neurotrauma and promote post-injury recovery is necessary. The objective of the current study is to systematically review nutritional and dietary interventions for neurotrauma prevention and mTBI recovery to direct clinical decision-making and identify future areas of research. This systematic review, without a specified time-period, was performed in PubMed, Scopus, Cochrane, CINAHL, and Web of Science followed by a manual search of references. Search strings were generated by a research librarian. Studies were included if they: 1) investigate human subjects with mTBI or SRHI; 2) investigate a supplement/ingredient of dietary supplement sold in the U.S. or dietary intervention without classification as a drug or prohibitive statement against use by the U.S. Food and Drug Administration (FDA); 3) assess a quantifiable outcome; and 4) are published in English in a peer-reviewed journal with an accessible full-length article. Studies were excluded if: 1) the study included non-mTBI or SRHI subjects (e.g., moderate/severe TBI, stroke); 2) mTBI is not assessed separately from moderate/severe mTBI; or 3) the studies that required intracranial hemorrhage. Fifteen studies from 12 unique subject populations met inclusion and exclusion criteria. A total of 1139 mTBI or SRHI subjects were enrolled across intervention arms in the study populations. A total of eight intervention were studied. Omega-3 fatty acid (n-3FA), melatonin, and Pinus radiata were the only interventions examined in multiple studies. Studies included 10 randomized-control trials, three prospective observational studies, and two retrospective observational studies. Seven of the 15 studies had a low risk of bias. Eleven studies reported benefit of the intervention. Strongest evidence supports n-3FA utility for neurotrauma prevention in athletes exposed to SRHI. Both Pinus radiata and melatonin may have benefit for persistent post-concussion symptoms; however, additional multi-center studies are necessary prior to making a definitive conclusion on these supplements' efficacy. Future studies should continue to assess both novel interventions and additional interventions examined in this review to bring additional evidence to the burgeoning field of nutritional and dietary interventions for SRHI and mTBI.

RESUMEN

OBJECTIVES: The arts therapies include music therapy, dance movement therapy, art therapy and dramatherapy. Preferences for art forms may play an important role in engagement with treatment. This survey was an initial exploration of who is interested in group arts therapies, what they would choose and why. DESIGN: An online cross-sectional survey of demographics, interest in and preferences for the arts therapies was designed in collaboration with patients. The survey took 10 min to complete, including informed consent and 14 main questions. Summary statistics, multinomial logistic regression and thematic analysis were used to analyse the data. SETTING: Thirteen National Health Service mental health trusts in the UK asked mental health patients and members of the general population to participate. PARTICIPANTS: A total of 1541 participants completed the survey; 685 mental health patients and 856 members of the general population. All participants were over 18 years old, had capacity to give informed consent and sufficient understanding of English. Mental health patients had to be using secondary mental health services. RESULTS: Approximately 60% of participants would be interested in taking part in group arts therapies. Music therapy was the most frequent choice among mental health patients (41%) and art therapy was the most frequent choice in the general population (43%). Past experience of arts therapies was the most important predictor of preference for that same modality. Expectations of enjoyment, helpfulness, feeling capable, impact on mood and social interaction were most often reported as reasons for preferring one form of arts therapy. CONCLUSIONS: Large proportions of the participants expressed an interest in group arts therapies. This may justify the wide provision of arts therapies and the offer of more than one modality to interested patients. It also highlights key considerations for assessment of preferences in the arts therapies as part of shared decision-making.

RESUMEN

Adult barn owl hearing is acute, but development of this sense is not well understood. We, therefore, measured auditory brainstem responses in barn owls from before the onset of hearing (posthatch day 2, or P2) to adulthood (P69). The first consistent responses were detected at P4 for 1 and 2 kHz, followed by responses to 0.5 and 4 kHz at P9, and 5 kHz at P13. Sensitivity to higher frequencies increased with age, with responses to 12 kHz appearing about 2 months after hatching, once the facial ruff was mature. Therefore, these altricial birds achieve their sensitivity to sound during a prolonged period of development, which coincides with maturation of the skull and facial ruff (Haresign and Moiseff in Auk 105:699-705, 1988).

RESUMEN

BACKGROUND: Depression is of significant global concern. Despite a range of effective treatment options it is estimated that around one in five diagnosed with an acute depressive episode continue to experience enduring symptoms for more than 2 years. There is evidence for effectiveness of individual music therapy for depression. However, no studies have as yet looked at a group intervention within an NHS context. This study aims to assess the feasibility of conducting a randomised controlled trial of group music therapy for patients with long-term depression (symptom durations of 1 year or longer) within the community. METHODS: This is a single-centre randomised controlled feasibility trial of group music therapy versus wait-list control with a nested process evaluation. Thirty participants will be randomised with unbalanced allocation (20 to receive the intervention immediately, 10 as wait-list controls). Group music therapy will be offered three times per week in a community centre with a focus on songwriting. Data will be collected post-intervention, 3 and 6 months after the intervention finishes. We will examine the feasibility of recruitment processes including identifying the number of eligible participants, participation and retention rates and the intervention in terms of testing components, measuring adherence and estimation of the likely intervention effect. A nested process evaluation will consist of treatment fidelity analysis, exploratory analysis of process measures and end-of-participation interviews with participants and referring staff. DISCUSSION: Whilst group music therapy is an option in some community mental health settings, this will be the first study to examine group music therapy for this particular patient group. We will assess symptoms of depression, acceptability of the intervention and quality of life. We anticipate potential challenges in the recruitment and retention of participants. It is unclear whether offering the intervention three times per week will be acceptable to participants, particularly given participants' enduring symptoms and impact upon motivation. This study will provide data to inform both development of the intervention and to assess and inform the design of a full trial. TRIAL REGISTRATION: ISRCTN.com, ISRCTN18164037 .

RESUMEN

Auditory sensitivity was measured in a species of diving duck that is not often kept in captivity, the lesser scaup. Behavioral (psychoacoustics) and electrophysiological [the auditory brainstem response (ABR)] methods were used to measure in-air auditory sensitivity, and the resulting audiograms were compared. Both approaches yielded audiograms with similar U-shapes and regions of greatest sensitivity (2000-3000 Hz). However, ABR thresholds were higher than psychoacoustic thresholds at all frequencies. This difference was least at the highest frequency tested using both methods (5700 Hz) and greatest at 1000 Hz, where the ABR threshold was 26.8 dB higher than the behavioral measure of threshold. This difference is commonly reported in studies involving many different species. These results highlight the usefulness of each method, depending on the testing conditions and availability of the animals.

RESUMEN

Task analysis is a descriptive study methodology that has wide application in the health professions. Task analysis is particularly useful in assessment and definition of the knowledge, skills, and behaviors that define the scope of practice of a health profession or occupation. Jhpiego, a US-based nongovernmental organization, has adapted traditional task analysis methods in several countries in assessment of workforce education and practice issues. Four case studies are presented to describe the utility and adaptability of the task analysis approach. Traditional task analysis field survey methods were used in assessment of the general and maternal-child health nursing workforce in Mozambique that led to curriculum redesign, reducing the number of education pathways from 4 to 2. The process of health system strengthening in Liberia, following a long history of civil war conflict, included a traditional task analysis study conducted among 119 registered nurses and 46 certified midwives who had graduated in the last 6 months to 2 years to determine gaps in education and preparation. An innovative approach for data collection that involves "playing cards" to document participant opinions (Task Master, Mining for Data) was developed by Jhpiego for application in other countries. Results of a task analysis involving 54 nurses and 100 nurse-midwives conducted in Lesotho were used to verify the newly drafted scope and standards of practice for nurses and to inform planning for a competency-based preservice curriculum for nursing. The Nursing and Midwifery Council developed a 100-question licensing examination for new graduates following a task analysis in Botswana. The task analysis process in each country resulted in recommendations that were action oriented and were implemented by the country governments. For maximal utility and ongoing impact, a task analysis study should be repeated on a periodic basis and more frequently in countries undergoing rapid change in development of workforce policy.

RESUMEN

In this paper, we compare some of the neural strategies for sound localization and encoding interaural time differences (ITDs) in three predatory species of Reptilia, alligators, barn owls and geckos. Birds and crocodilians are sister groups among the extant archosaurs, while geckos are lepidosaurs. Despite the similar organization of their auditory systems, archosaurs and lizards use different strategies for encoding the ITDs that underlie localization of sound in azimuth. Barn owls encode ITD information using a place map, which is composed of neurons serving as labeled lines tuned for preferred spatial locations, while geckos may use a meter strategy or population code composed of broadly sensitive neurons that represent ITD via changes in the firing rate.

RESUMEN

BACKGROUND AND OBJECTIVES: There is an emerging evidence base for the use of music therapy in the treatment of severe mental illness. Whilst different models of music therapy have been developed in mental health care, none have specifically accounted for the features and context of acute in-patient settings. This review aimed to identify how music therapy is provided for acute adult psychiatric in-patients and what outcomes have been reported. REVIEW METHODS: A systematic review using medical, psychological and music therapy databases. Papers describing music therapy with acute adult psychiatric in-patients were included. Analysis utilised narrative synthesis. RESULTS: 98 papers were identified, of which 35 reported research findings. Open group work and active music making for nonverbal expression alongside verbal reflection was emphasised. Aims were engagement, communication and interpersonal relationships focusing upon immediate areas of need rather than longer term insight. The short stay, patient diversity and institutional structure influenced delivery and resulted in a focus on single sessions, high session frequency, more therapist direction, flexible use of musical activities, predictable musical structures, and clear realistic goals. Outcome studies suggested effectiveness in addressing a range of symptoms, but were limited by methodological shortcomings and small sample sizes. Studies with significant positive effects all used active musical participation with a degree of structure and were delivered in four or more sessions. CONCLUSIONS: No single clearly defined model exists for music therapy with adults in acute psychiatric in-patient settings, and described models are not conclusive. Greater frequency of therapy, active structured music making with verbal discussion, consistency of contact and boundaries, an emphasis on building a therapeutic relationship and building patient resources may be of particular importance. Further research is required to develop specific music therapy models for this patient group that can be tested in experimental studies.

RESUMEN

Axons from the nucleus magnocellularis (NM) and their targets in nucleus laminaris (NL) form the circuit responsible for encoding interaural time differences (ITDs). In barn owls, NL receives bilateral inputs from NM such that axons from the ipsilateral NM enter NL dorsally, while contralateral axons enter from the ventral side. These afferents and their synapses on NL neurons generate a tone-induced local field potential, or neurophonic, that varies systematically with position in NL. From dorsal to ventral within the nucleus, the best interaural time difference (ITD) of the neurophonic shifts from contralateral space to best ITDs around 0 µs. Earlier recordings suggested that in NL, iso-delay contours ran parallel to the dorsal and ventral borders of NL (Sullivan WE, Konishi M. Proc Natl Acad Sci U S A 83:8400-8404, 1986). This axis is orthogonal to that seen in chicken NL, where a single map of ITD runs from around 0 µs ITD medially to contralateral space laterally (Köppl C, Carr CE. Biol Cyber 98:541-559, 2008). Yet the trajectories of the NM axons are similar in owl and chicken (Seidl AH, Rubel EW, Harris DM, J Neurosci 30:70-80, 2010). We therefore used clicks to measure conduction time in NL and made lesions to mark the 0 µs iso-delay contour in multiple penetrations along an isofrequency slab. Iso-delay contours were not parallel to the dorsal and ventral borders of NL; instead the 0 µs iso-delay contour shifted systematically from a dorsal position in medial NL to a ventral position in lateral NL. Could different conduction delays account for the mediolateral shift in the representation of 0 µs ITD? We measured conduction delays using the neurophonic potential and developed a simple linear model of the delay-line conduction velocity. We then raised young owls with time-delaying earplugs in one ear (Gold JI, Knudsen EI, J Neurophysiol 82:2197-2209, 1999) to examine map plasticity.

RESUMEN

OBJECTIVES: Not all patients with post-traumatic stress disorder (PTSD) respond to cognitive behavioural therapy (CBT). Literature suggests group music therapy might be beneficial in treating PTSD. However, feasibility and effectiveness have not been assessed. The study objectives were to assess whether group music therapy was feasible for patients who did not respond to CBT, and whether it has an effect on PTSD symptoms and depression. DESIGN: The study employed mixed methods comprising of an exploratory randomized controlled trial, qualitative content analysis of therapy, and patient interviews. METHOD: Patients with significant PTSD symptoms (n = 17) following completion of CBT were randomly assigned to treatment (n = 9) or control groups (n = 8). The treatment group received 10 weeks of group music therapy after which exit interviews were conducted. Control group patients were offered the intervention at the end of the study. Symptoms were assessed on the Impact of Events Scale-Revised and Beck Depression Inventory II at the beginning and end of treatment. RESULTS: Treatment-group patients experienced a significant reduction in severity of PTSD symptoms (-20.18; 95% confidence interval [CI]: [-31.23, -9.12]) and a marginally significant reduction in depression (-11.92; 95%CI: [-24.05, 0.21]) at 10 weeks from baseline compared to the control. Patients viewed music therapy as helpful and reported experiences concur with current literature. CONCLUSIONS: Group music therapy appears feasible and effective for PTSD patients who have not sufficiently responded to CBT. Limitations include the small sample size and lack of blinding. Further research should address these limitations, test sustainability, and identify specific factors that address symptoms in treatment.

RESUMEN

Turtles, like other amphibious animals, face a trade-off between terrestrial and aquatic hearing. We used laser vibrometry and auditory brainstem responses to measure their sensitivity to vibration stimuli and to airborne versus underwater sound. Turtles are most sensitive to sound underwater, and their sensitivity depends on the large middle ear, which has a compliant tympanic disc attached to the columella. Behind the disc, the middle ear is a large air-filled cavity with a volume of approximately 0.5 ml and a resonance frequency of approximately 500 Hz underwater. Laser vibrometry measurements underwater showed peak vibrations at 500-600 Hz with a maximum of 300 µm s(-1) Pa(-1), approximately 100 times more than the surrounding water. In air, the auditory brainstem response audiogram showed a best sensitivity to sound of 300-500 Hz. Audiograms before and after removing the skin covering reveal that the cartilaginous tympanic disc shows unchanged sensitivity, indicating that the tympanic disc, and not the overlying skin, is the key sound receiver. If air and water thresholds are compared in terms of sound intensity, thresholds in water are approximately 20-30 dB lower than in air. Therefore, this tympanic ear is specialized for underwater hearing, most probably because sound-induced pulsations of the air in the middle ear cavity drive the tympanic disc.

RESUMEN

Animals, including humans, use interaural time differences (ITDs) that arise from different sound path lengths to the two ears as a cue of horizontal sound source location. The nature of the neural code for ITD is still controversial. Current models differentiate between two population codes: either a map-like rate-place code of ITD along an array of neurons, consistent with a large body of data in the barn owl, or a population rate code, consistent with data from small mammals. Recently, it was proposed that these different codes reflect optimal coding strategies that depend on head size and sound frequency. The chicken makes an excellent test case of this proposal because its physical prerequisites are similar to small mammals, yet it shares a more recent common ancestry with the owl. We show here that, like in the barn owl, the brainstem nucleus laminaris in mature chickens displayed the major features of a place code of ITD. ITD was topographically represented in the maximal responses of neurons along each isofrequency band, covering approximately the contralateral acoustic hemisphere. Furthermore, the represented ITD range appeared to change with frequency, consistent with a pressure gradient receiver mechanism in the avian middle ear. At very low frequencies, below 400 Hz, maximal neural responses were symmetrically distributed around zero ITD and it remained unclear whether there was a topographic representation. These findings do not agree with the above predictions for optimal coding and thus revive the discussion as to what determines the neural coding strategies for ITDs.

RESUMEN

BACKGROUND: In 2002, the University of Washington School of Nursing (SON) partnered with Bastyr University on a five-year plan to offer a four-week intensive "CAM Camp" (CAMp) for SON faculty members and medical students from across the country. The four-week educational program introduced attendees to various complementary and alternative medicine (CAM) modalities through didactic and experiential learning. OBJECTIVE: To enhance complementary and alternative medicine content in a SON curriculum and to increase SON faculty knowledge and understanding about (1) the range of CAM therapies, (2) the theoretic and cultural backgrounds of these therapies, and (3) their potential contributions to the health of diverse populations. DESIGN: A descriptive pretest, posttest design was used to compare pre-CAMp CAM knowledge and CAM course content with post-CAMp knowledge levels of faculty and course CAM content. RESULTS: On post-CAMp surveys, familiarity with CAM modalities was rated with mixed results as compared with positive reports on the qualitative interviews. Interview results were more positive about CAM in general and were less specific about individual CAM topics. Statistically significant increases in competences were evident in each of 13 competencies rated with four competencies at P < .01. The number of required and elective courses containing CAM content increased as did the CAM content in continuing education conferences offered by the SON.

RESUMEN

In the auditory system, precise encoding of temporal information is critical for sound localization, a task with direct behavioral relevance. Interaural timing differences (ITDs) are computed using axonal delay lines and cellular coincidence detectors in nucleus laminaris (NL). We present morphological and physiological data on the timing circuits in the emu, Dromaius novaehollandiae, and compare these results with those from the barn owl (Tyto alba) and the domestic chick (Gallus gallus). Emu NL was composed of a compact monolayer of bitufted neurons whose two thick primary dendrites were oriented dorsoventrally. They showed a gradient in dendritic length along the presumed tonotopic axis. The NL and nucleus magnocellularis (NM) neurons were strongly immunoreactive for parvalbumin, a calcium-binding protein. Antibodies against synaptic vesicle protein 2 and glutamic acid decarboxlyase revealed that excitatory synapses terminated heavily on the dendritic tufts, while inhibitory terminals were distributed more uniformly. Physiological recordings from brainstem slices demonstrated contralateral delay lines from NM to NL. During whole-cell patch-clamp recordings, NM and NL neurons fired single spikes and were doubly rectifying. NL and NM neurons had input resistances of 30.0 +/- 19.9 Momega and 49.0 +/- 25.6 Momega, respectively, and membrane time constants of 12.8 +/- 3.8 ms and 3.9 +/- 0.2 ms. These results provide further support for the Jeffress model for sound localization in birds. The emu timing circuits showed the ancestral (plesiomorphic) pattern in their anatomy and physiology, while differences in dendritic structure compared to chick and owl may indicate specialization for encoding ITDs at low best frequencies.

RESUMEN

A recent trend discouraging or not offering women a choice to labor after a cesarean birth has resulted in higher cesarean birth rates and lower rates of vaginal birth after cesarean birth (VBAC). The few studies describing midwifery practice have demonstrated favorable outcomes; however, the studies are too small to thoroughly evaluate critical outcomes. In this retrospective descriptive study, clinical outcome data were obtained from eight midwifery practices. The aims were to collect, aggregate, and analyze data from multiple midwifery practices and then describe outcomes. Usable data representing 649 trials of labor were submitted. Overall, 72% (range 64%-100%) of women gave birth vaginally. Mean infant birth weight was 3,501 (SD = 534) g, and the mean Apgar scores were 7.99 (SD = 1.4; median 8) at 1 minute and 8.84 (SD = 0.8; median 9) at 5 minutes. Only 5.3% (n = 14) of infants were admitted to the neonatal intensive care unit. This small retrospective study demonstrates similar outcomes to those reported in the current literature. A larger prospective study to carefully describe midwifery care outcomes using a common data collection method is needed to provide evidence for determining the continuation of VBAC as part of midwifery care.

RESUMEN

Midwives have been providing care for women choosing vaginal birth after cesarean birth (VBAC) for over 20 years. The 1999 American College of Obstetrician Gynecologist (ACOG) guidelines and recent studies questioning the relative safety of VBAC have raised concerns about continuing to offer this option. As part of an effort to understand VBAC care provided by midwives, this study used a national survey sample to examine practices, scope, and recent changes in the provision of VBAC care. The survey, which included demographic and practice items was mailed in late 2000 to a purposeful sample of 325 midwifery practices. The return rate was 62%. Nearly all (94%) of the responding practices were providing VBAC care, and almost half of them (43%) stated that their ability to do so had changed within the past 2 years secondary to recent studies in the obstetric literature, the 1999 ACOG statement, and concerns from third-party payers. Criteria for offering VBAC are stricter, and consent forms are more extensive. Other changes included the need for additional or more intensive support services, in-house anesthesia, and surgery backup. Midwives continue to provide VBAC care, although with some increased restrictions. This study provides background for future research that will determine how midwifery care affects the rate of successful VBACs.
