Knowledge and Attitudes of Potential Community Health Worker Employers: Findings from the State of Arkansas, USA.

Community health workers (CHWs) are critical to health equity efforts, but sustaining CHW programs is challenging. Understanding stakeholders' knowledge and attitudes about CHWs can inform strategies to advance this important workforce. The authors implemented an online survey of potential CHW employers to learn their perceptions of CHWs' roles, outcomes, and abilities to affect important health outcomes, and of key issues that affect CHW employment. The survey was disseminated statewide to a diverse group of stakeholders working in healthcare in Arkansas. A total of 151 surveys were collected and included in the analysis. The organizations represented by respondents primarily included state and local agencies and clinics, followed by healthcare systems. The main professional roles of survey respondents were administrators and clinicians, followed by healthcare staff. Over 90% of respondents agreed that CHWs have the ability to conduct community outreach, serve as a liaison, navigate health systems, provide coaching support, and participate in care coordination. Over 90% of healthcare administrators, clinicians, and policymakers agreed that standardized training and a clear definition of role and scope of practice are important to CHW employment. However, almost two-thirds of respondents' organizations were not employing CHWs, adding to previous research which has primarily focused on CHW employers' attitudes. Understanding and addressing attitudes of those who lack experience with CHWs can help to identify actions needed to promote and increase adoption of CHWs. The authors share how they are using these data to engage stakeholders in decision-making and adoption of CHWs in their state.

A 10-Year Systematic Review of Photovoice Projects With Youth in the United States.

INTRODUCTION: Photovoice is a method used in community-based participatory research that places cameras in the hands of people and invites them to record their lives, engage in critical dialogue, and advocate for changes needed in their communities. This article presents a review of the literature from 2010 to 2019 on photovoice projects implemented with U.S. youth informed by an emancipatory research conceptual framework. METHOD: Information on 30 project elements was extracted from each of the 47 publications, representing 39 unique projects that met our inclusion criteria. Projects were also assessed for whether they met the goals of photovoice as originally conceptualized by Wang and Burris in 1997. RESULTS: Participants, policy makers, and community members were affected by photovoice projects. Outcomes ranged from researcher specific needs to community change and policy awareness and changes. Common outcomes included (1) gaining knowledge, (2) participant empowerment, (3) community change/action, (4) new partnerships, and (5) reaching policy makers. Of the 39 unique projects, 17 addressed all three photovoice goals, 12 addressed two, and 10 addressed only one. All the projects met the goal of enabling participants to record and reflect their community's strengths and concerns. Twenty-four were aligned with all three principles of emancipatory research. DISCUSSION: Photovoice is a valuable, flexible tool that can enable participants to play an active, guiding role in assessing the needs and assets of their community. Through critical reflection and dialogue, youth can become change agents in their communities. No single set of strategies will work best for every project.

Relationships between depression, anxiety, and pain in a group of university music students.

There is emerging interest in studying the incidence of music-related injuries and problems among students. The current study drew on a data set collected from 287 music majors and minors at a large US midwestern university school of music in order to determine if correlations existed between anxiety and/or depression and the reported presence of physical pain, and to understand the nature of any such relationships. Physical pain symptoms were scored on a scale of 0 (none) to 10 (excruciating) and summed across 21 body regions. Depression and anxiety symptoms were scored as none (0), mild (1), moderate (2), or severe (3), and each summed across either 13 symptoms for depression or 8 symptoms for anxiety. The potential linear relationship among these variables was evaluated using F-tests (as part of ANOVAs) and linear regression parameter estimation techniques. The explanatory value of these relationships was evaluated using R² values. Results indicate a clear positive linear relationship between both depression and pain, and anxiety and pain. However, the presence of depression and/or anxiety symptoms was insufficient to explain variability in pain scores of these participants.

Increased cortical inhibition in persons with schizophrenia treated with clozapine.

It has been previously demonstrated that unmedicated persons with schizophrenia have deficits in cortical inhibition (CI) as indexed with transcranial magnetic stimulation (TMS). This inhibition is largely mediated by cortical GABAergic mechanisms. It has also been demonstrated that these inhibitory deficits may be normalized with the use of atypical antipsychotic medications. The purpose of this study, therefore, was to examine the effects of clozapine on TMS measures of CI and to compare these effects to unmedicated persons with schizophrenia and healthy subjects. We used two TMS inhibitory paradigms: short interval intra-cortical inhibition (SICI) and the cortical silent period (CSP) to evaluate CI in 10 clozapine-treated persons with schizophrenia, 6 unmedicated persons with schizophrenia and 10 healthy subjects. Clozapine-treated persons with schizophrenia had significantly longer CSPs compared with healthy subjects and unmedicated persons with schizophrenia. There were no significant differences in SICI between groups, however, the severity of psychotic symptoms was correlated with reduced SICI across all persons with schizophrenia. Our findings suggest that clozapine treatment is associated with greater CI in persons with schizophrenia and this increase may be related to potentiation of cortical GABAergic receptor mediated inhibitory neurotransmission. Our results also confirm previous findings suggesting that deficits in CI are related to the severity of psychotic symptoms in persons with schizophrenia.

A comparative study of the effects of repetitive paired transcranial magnetic stimulation on motor cortical excitability.

OBJECTIVES: Various methods of application of repetitive transcranial magnetic stimulation (TMS) have been evaluated for their potential capacity to alter motor cortical excitability. Initial research suggests that the repetitive application of paired TMS pulses (repetitive paired pulse TMS (rppTMS)) may have greater effects on cortical excitability, perhaps through the facilitation of I-wave interaction. We aimed to compare the post-train effects of 15 min trains of rppTMS to investigate the potential therapeutic application of this technique as well as to compare it to a standard high frequency repetitive TMS paradigm. METHODS: Ten normal subjects received three 15 min sessions of rppTMS, 5 Hz high frequency rTMS and sham TMS in randomised order. rppTMS consisted of a single train of 180 pulse pairs (0.2 Hz, 1.5 ms inter-stimulus interval, supra-threshold intensity) administered over 15 min. The rTMS condition involved 750 pulses provided in 5s 5 Hz trains with a 25s inter-train interval at 90% of the RMT. Motor evoked potential size and cortical silent period duration were assessed before and after each session. RESULTS: There were no significant changes in cortical excitability produced by any of the stimulation conditions. Five hertz rTMS produced an increase in cortical silent period duration (p=0.004) which was not affected by rppTMS. CONCLUSIONS: Fifteen minutes trains of 1.5ms rppTMS do not substantially increase post train cortical excitability. Repetitive brief trains of 5Hz rTMS also do not alter excitability but appear to effect cortical inhibition.

A comprehensive review of the effects of rTMS on motor cortical excitability and inhibition.

Repetitive transcranial magnetic stimulation (rTMS) procedures are being widely applied in therapeutic and investigative studies. Numerous studies have investigated the effects of rTMS on cortical excitability and inhibition, yielding somewhat contradictory results. The purpose of this study was to comprehensively review this literature to guide the selection of methodology in therapeutic studies. We conducted a comprehensive review of all identified studies that investigated effects of low and/or high frequency rTMS on motor cortical excitability or inhibition. Low frequency rTMS appears to produce a transient reduction in cortical excitability as assessed by motor evoked potential (MEP) size and produces no substantial effect on cortical inhibition. High frequency rTMS appears to produce a persistent increase in MEP size and a reduction in cortical inhibition measured with paired pulse methods although few studies have investigated frequencies greater than 5Hz. A number of novel stimulation paradigms have significant potential for altering cortical excitability but require further investigation. Although commonly applied forms of rTMS have effects on cortical excitability, more substantial effects may be obtained through the use of novel stimulation paradigms or innovative approaches to the stimulation of areas connected to a potential target site. Further research is required, however, before these paradigms can be more widely adopted.

Reduced cerebellar inhibition in schizophrenia: a preliminary study.

OBJECTIVE: Postmortem and structural imaging studies suggest that patients with schizophrenia have disrupted cerebellar activity. It has been speculated that these abnormalities mediate disorganized thought processes and psychosis. The authors' goal was to use transcranial magnetic stimulation to measure cerebellar inhibition, a proxy of cerebellar activity, as the principal output of the cerebellum is inhibitory. METHOD: Cerebellar inhibition was accomplished by delivering a magnetic cerebellar conditioning stimulus 5-15 msec before a magnetic test stimulus to the motor cortex. The cerebellar conditioning stimulus inhibits the size of the motor evoked potential produced by the test stimulus by approximately 50%. Ten patients with schizophrenia and 10 healthy comparison subjects completed the cerebellar inhibition protocol. RESULTS: Patients with schizophrenia demonstrated significant deficits in cerebellar inhibition compared with healthy subjects. CONCLUSIONS: The authors conclude that deficits in cerebellar inhibitory activity in schizophrenia may be the result of an abnormality in the cerebellum or disrupted cerebellar-thalamic-cortical connectivity.
