    Abstract We investigate the effect of Supplemental Nutrition Assistance Program (SNAP) work requirements on work effort for a particularly disadvantaged subgroup of potential SNAP participants. Individuals age out of SNAP work requirements at age fifty and requirements are occasionally waived in certain areas. We leverage this policy variation in a regression discontinuity research design and find that, for adults with low income and low education, aging out of work requirements decreases employment, hours worked, and the probability of working over twenty hours per week only when requirements are in effect. This drop in work effort is not apparent among low‐income adults in general and is driven by individuals leaving the labor force because they report being unable to work or because they retire. The drop is smaller when states do not provide qualifying work opportunities. Overall, although we find meaningful effects consistent with theory for a subset of low‐income adults, it is not clear that the overall number affected is sufficiently large to translate to noticeable labor market effects among low‐income adults without dependents in general.

    Abstract Young adults, particularly college students, report a higher prevalence of risky sexual behavior than the general population, increasing their likelihood for unplanned pregnancy, sexually transmitted infections (STIs), and negative psychological outcomes. Although sexual risk behavior and its consequences are a major public health concern, current prevention literature is insufficient and relies on sexual risk measures with limited psychometric support. The present study, therefore, examined the psychometric properties of a sexual risk survey (SRS; Turchik, Garske, in Arch Sex Behav 38:936-948, 2009), using data from the first year of a longitudinal study following the outcomes of college students with and without attention-deficit/hyperactivity disorder (ADHD; N = 410). Principal components analyses were conducted to assess the factorial structure of the SRS comparing results from a general college population and a college population considered to be high-risk (ADHD). Results revealed four components across both samples. Internal consistency estimates for component scores and total scores ranged from .627 to 918. Implications of the findings are discussed and suggestions for future studies are advanced.

    Abstract In spite of important recent work on the history of technology and the dynamics of technological change in Latin America, the literature in this field remains relatively undeveloped. In part, this is due to a relative scarcity of available sources for conducting research. This research note argues that national patent records are an important and untapped source for a wide range of studies on technology and technological change. The research note announces the creation of major new comprehensive databases of patent records in several Latin American countries, part of a larger, ongoing project to compile and make publically accessible patent records across the region. We also provide an introduction to the history of patents in Latin America, followed by a discussion of both the use (and misuse) of patents as historical evidence and recent advances in collecting and using patent evidence in Latin America. A pesar de valiosos trabajos sobre la historia de la tecnología y las dinámicas del cambio tecnológico en América Latina, no se puede afirmar que exista una extensa historiografía sobre el asunto. En parte, esto se debe a la escasez relativa de fuentes de investigación. Este artículo sostiene, precisamente, que los registros nacionales de patentes han sido muy poco explotados y pueden constituir una importante fuente para una amplia gama de estudios sobre la tecnología y el cambio tecnológico. En concreto, se anuncia la creación de nuevas y exhaustivas bases de datos históricas de patentes en varios países de América Latina, como parte de un proyecto en curso, de mayor envergadura, que pretende compilar y hacer accesible al público los registros de toda la región. Se aporta, en suma, una introducción sobre la historia de las patentes en América Latina, seguida de un análisis de las ventajas e inconvenientes de su uso como evidencia histórica, así como de los últimos avances en su recopilación.

    Abstract Women who delay or do not attend Papanicolaou (Pap) screening are at increased risk for cervical cancer. Trials in countries with organized screening programs have demonstrated that mailing high-risk (hr) human papillomavirus (HPV) self-sampling kits to under-screened women increases participation, but U.S. data are lacking. HOME is a pragmatic randomized controlled trial set within a U.S. integrated healthcare delivery system to compare two programmatic approaches for increasing cervical cancer screening uptake and effectiveness in under-screened women (>3.4years since last Pap) aged 30-64years: 1) usual care (annual patient reminders and ad hoc outreach by clinics) and 2) usual care plus mailed hrHPV self-screening kits. Over 2.5years, eligible women were identified through electronic medical record (EMR) data and randomized 1:1 to the intervention or control arm. Women in the intervention arm were mailed kits with pre-paid envelopes to return samples to the central clinical laboratory for hrHPV testing. Results were documented in the EMR to notify women's primary care providers of appropriate follow-up. Primary outcomes are detection and treatment of cervical neoplasia. Secondary outcomes are cervical cancer screening uptake, abnormal screening results, and women's experiences and attitudes towards hrHPV self-sampling and follow-up of hrHPV-positive results (measured through surveys and interviews). The trial was designed to evaluate whether a programmatic strategy incorporating hrHPV self-sampling is effective in promoting adherence to the complete screening process (including follow-up of abnormal screening results and treatment). The objective of this report is to describe the rationale and design of this pragmatic trial.

  7. Article: Cervical VEMP Threshold Response Curve in the Identification of Ménière’s Disease

    Abstract Purpose: To investigate the sensitivity/specificity of a shift upward in the most sensitive frequency of the cervical vestibular evoked myogenic potential (cVEMP) threshold-response curve in the identification of Ménière’s disease (MD). A secondary purpose was to investigate the clinical characteristics that had an impact on the sensitivity/specificity and to adjust the criteria for a positive shift upward in the cVEMP curve to maximize performance of the test.
    Research Design: A retrospective review of patients diagnosed with MD and those without MD.
    Study Sample: Two hundred ninety-four patients met the inclusion criteria of symptom complaints of spontaneous events of vertigo and a full vestibular and balance evaluation with cVEMP threshold-response curve testing. Two hundred six of these patients were diagnosed with MD, and 88 patients were determined to be non-MD.
    Data Collection and Analysis: Review of the patients’ medical records was used to extract data on the results of the cVEMP curve, age, gender, duration from time of onset of spontaneous events, pure tone average from hearing test, and water caloric asymmetry. Student’s t -test, χ 2 test, receiver operating characteristic (ROC) curve with area under the curve (AUC), Pearson correlation coefficient, and sensitivity/specificity from 2 × 2 tables were all used in the analysis.
    Results: Basic sensitivity/specificity for a shift upward in the most sensitive frequency to 1000 Hz in the cVEMP threshold-response curve was 0.47/0.64 respectively. Clinical characteristics that were found to have a significant impact on the sensitivity/specificity were age equal to or above 60 yr and a caloric asymmetry ≥25%. Various combinations of age and caloric with the requirement of a shift upward in the cVEMP curve most sensitive frequency to 1000 Hz resulted in significant but modest improvements in sensitivity/specificity. However, the overall performance was not shown acceptable for routine clinical use with maximum sensitivity at 0.73. Therefore, placing an emphasis on specificity over sensitivity results showed specificity of 0.95 for those under 60 yr and 0.90 for those 60 yr of age or older with sensitivity at 0.20, but only in the context of a ≥25% caloric asymmetry.
    Conclusions: We recommend the use of the shift upward to 1000 Hz with a caloric asymmetry as the clinical protocol to maximize the use of the cVEMP threshold-response curve for assistance in the identification of MD, in the context of a ≥25% caloric asymmetry. This implies that if the test is negative no interpretation of identification of MD can be made. If the test is positive the results can be used to increase the argument for MD since the probability of the result being a false positive is only 5–10%.

    Abstract This paper provides insight into barriers to participation in welfare programs for a valuable subset of our population— agricultural laborers. To do this, we provide an overview of California agricultural labor participation in social welfare programs. Based on the program eligibility criteria, we identify three potential barriers to program access: (1) legal status, (2) seasonality of employment, and (3) physical access to county enrollment offices. We then use the program eligibility criteria and benefit calculations to establish benefit kinks for a well-used aid program: the Supplemental Nutrition Assistance Program (SNAP, known as CalFresh in California). Then, using the NAWS dataset, we present a comparison of families who report using CalFresh with those who do not, examine bunching around the income thresholds, and construct a measure of real income that includes program benefits.

    Abstract: Elevated risk of developing Alzheimer’s disease (AD) is associated with hypomorphic variants ...

    Abstract Elevated risk of developing Alzheimer’s disease (AD) is associated with hypomorphic variants of TREM2, a surface receptor required for microglial responses to neurodegeneration, including proliferation, survival, clustering, and phagocytosis. How TREM2 promotes such diverse responses is unknown. Here, we find that microglia in AD patients carrying TREM2 risk variants and TREM2-deficient mice with AD-like pathology have abundant autophagic vesicles, as do TREM2-deficient macrophages under growth-factor limitation or endoplasmic reticulum (ER) stress. Combined metabolomics and RNA sequencing (RNA-seq) linked this anomalous autophagy to defective mammalian target of rapamycin (mTOR) signaling, which affects ATP levels and biosynthetic pathways. Metabolic derailment and autophagy were offset in vitro through Dectin-1, a receptor that elicits TREM2-like intracellular signals, and cyclocreatine, a creatine analog that can supply ATP. Dietary cyclocreatine tempered autophagy, restored microglial clustering around plaques, and decreased plaque-adjacent neuronal dystrophy in TREM2-deficient mice with amyloid-β pathology. Thus, TREM2 enables microglial responses during AD by sustaining cellular energetic and biosynthetic metabolism.
