The current study assesses the relationship between continuing education (CE) with a focus on pediatrics and children with special heath care needs and how CE influences the knowledge and comfort levels of prehospital providers who treat these cases. Data are survey responses provided by paramedic and emergency medical technician (EMT) level providers (N = 575) in Los Angeles County. Regression models assessed the relationship between pediatric-focused continuing education and EMTs’ knowledge of and comfort with pediatric cases, adjusting for relevant covariates. EMTs’ participation in continuing education focusing on pediatrics and special health care needs was significantly associated with an increase in perceived comfort and knowledge. Among EMTs who did not receive continuing education focused on either pediatrics or special health care needs, the most frequently reported barrier to education was a perceived lack of availability. The impact of continuing education on perceived comfort and knowledge was more pronounced than the effect of prior experience, especially considering the limited prevalence of provider exposure to pediatric and childhood special health care needs cases compared to adult cases. Expanding educational opportunities is a promising approach to increasing the comfort and knowledge of EMTs who transport and care for pediatric cases.

AbstractRock aggregates constitute the enormous volume of inert construction material used around the globe. The petrologic description as igneous, sedimentary, and metamorphic types establishes the intrinsic formation pattern of the parent rock. The engineering properties of these rocks vary due to the differences in the transformation process (e.g. hydrothermal deposits) and weathering effect. The two most common mechanical tests used to investigate the performance of aggregates are the Los Angeles (LA) and micro-Deval (MD) tests. This study reviewed the geological parameters (including mineralogy, grain and crystal size, grain shape, and porosity) and the relationship to Los Angeles and micro-Deval tests. It was found that high content of primary minerals in rocks (e.g. quartz and feldspar) is a significant parameter for performance evaluation. Traces of secondary and accessory minerals also affect the performance of rocks, although in many cases it is based on the percentage. Furthermore, some studies showed that the effect of mineralogic composition on mechanical strength is not sufficient to draw final conclusions of mechanical performance; therefore, the impact of other textural characteristics should be considered. The disposition of grain size and crystal size (e.g. as result of lithification) showed that rocks composed of fine-grain textural composition of ≤ 1 mm enhanced fragmentation and wear resistance than medium and coarse grained (≥ 1 mm). The effect of grain shape was based on convex and concave shapes and flat and elongated apexes of tested samples. The equidimensional form descriptor of rocks somehow improved resistance to impact from LA than highly flat and elongated particles. Lastly, the distribution of pore space investigated by means of the saturation method mostly showed moderate (R = 0.50) to strong (R = 0.90) and positive correlations to LA and MD tests.

Abstract Objective: To understand the relationship between drug use, food insecurity (FI), and mental health among men who have sex with men (MSM). Design: Cohort study (2014-2019) with at least one follow-up. Setting: Visits at 6-month intervals included self-assessment for FI and depressive symptoms. Urine testing results confirmed drug use. Factors associated with FI were assessed using multiple logistic regression with random effects for repeated measures. General structural equation modeling tested whether FI mediates the relationship between drug use and depressive symptoms. Participants: Data were from HIV-positive and high-risk HIV negative MSM in Los Angeles, CA (n=431; 1,192 visits). Results: At baseline, FI was reported by 50.8% of participants, depressive symptoms in 36.7%, and 52.7% of urine screening tests were positive for drugs (i.e., marijuana, opioids, methamphetamine, cocaine, ecstasy). A positive drug test was associated with a 96% increase in the odds of being food insecure (95% CI: 1.26-3.07). Compared to those with high food security, individuals with very low food security have a nearly 7-fold increase in the odds of reporting depressive symptoms (95% CI: 3.71-11.92). Findings showed 14.9% of the association between drug use (exposure) and depressive symptoms (outcome) can be explained by FI (mediator). Conclusion: The prevalence of FI among this cohort of HIV-positive and high-risk HIV-negative MSM was high; the association between drug use and depressive symptoms was partially mediated by FI. Findings suggest that enhancing access to food and nutrition may improve mood in the context of drug use, especially among MSM at risk for HIV-transmission.

Primary care physicians face increasing amounts of administrative work (e.g., entering notes into electronic health records, managing insurance issues, delivering test results, etc.) outside of face-to-face patient visits. The objective of this study is to qualitatively describe the experience that primary care physicians have with administrative work, with an emphasis on their beliefs about their job role. I conducted semi-structured interviews with 28 family physicians and internists in Chicago, Los Angeles, and Miami and qualitatively analyzed themes from interview transcripts using the grounded theory approach. Two major themes concerning the relationship between primary care physicians and administrative work were discovered: (a) Administrative work was not central to primary care physicians’ job role beliefs, and (b) “below license” work should be delegated to nonphysicians. Job roles should be considered in future efforts to reduce physician administrative work in primary care.

Institutional Participation

The threat of deportation shapes the way that unauthorized immigrants and their families interact with social institutions. For example, the adult children of unauthorized immigrants might avoid institutions that keep formal records (“surveilling” institutions) because such institutions could potentially expose their families to deportation. Using intergenerational data from the Immigration and Intergenerational Mobility in Metropolitan Los Angeles survey, we examine the relationship between immigrant parents’ authorization status and their adult children’s institutional participation ( n = 3,283). Results from Poisson and propensity-weighted regression models suggest that the adult children of unauthorized immigrants were more likely to avoid surveilling institutions, such as formal employment, than those with authorized parents. In contrast, parental immigration status was unrelated to their attachment to non-surveilling institutions, such as community groups or religious organizations. This finding suggests that the adult children of unauthorized immigrants are not systematically disengaged from all institutions but may avoid surveilling institutions in particular due to fear of their family’s deportation. This type of system avoidance may have long-term consequences for their social and economic mobility.

Although recent evidence suggests a beneficial effect of alcohol for patients with traumatic brain injury (TBI), the level of alcohol that confers the protective effect is unknown. Our objective was to investigate the relationship between admission blood alcohol concentration (BAC) and outcomes in patients with isolated moderate to severe TBI. From 2005 to 2009, the Los Angeles County Trauma Database was queried for all patients ≥14 years of age with isolated moderate to severe TBI and admission serum alcohol levels. Patients were then stratified into four levels based on admission BAC: None (0 mg/dL), low (0-100 mg/dL), moderate (100-230 mg/dL), and high (≥230 mg/dL). Demographics, patient characteristics, and outcomes were compared across levels. In evaluating 3794 patients, the mortality rate decreased with increasing BAC levels (linear trend P < 0.0001). In determining the relationship between BAC and mortality, multivariable logistic regression analysis demonstrated a high BAC level was significantly protective (adjusted odds ratio 0.55; 95% confidence interval: 0.38-0.8; P = 0.002). In the largest study to date, a high (≥230 mg/dL) admission BAC was independently associated with improved survival in patients with isolated moderate to severe TBI. Additional research is warranted to investigate the potential therapeutic implications.

BackgroundThere is a strong body of evidence supporting associations between interpersonal trauma (IPT) and substance use; however, this tends to focus on associations between childhood trauma and substance use in non-pregnant populations. Neonatal and obstetric outcomes are poorer among pregnant women with problematic substance use, yet few studies have explored IPT as a possible mechanism underlying their use of substances.AimTo explore the literature regarding the relationship between IPT and substance misuse among pregnant women.MethodA systematic search of relevant databases was conducted and a narrative review of the literature was undertaken. Titles, abstracts and full articles were screened against inclusion criteria. Data were extracted and quality assessed.FindingsA total of 15 studies were identified that suggested associations between negative life events and substance misuse in pregnant women/new mothers.ConclusionsAlthough a link between IPT and substance misuse is suggested, this review has highlighted a number of important gaps in the literature that warrant further investigation. These include a paucity of UK-based studies, and a lack of research that fully explores possible associations between IPT and substance use in pregnant women. Moreover, research to date has employed quantitative methodology.
