BACKGROUND This study examined interview data from the National Health and Nutrition Examination Survey from 2005 to 2016. OBJECTIVE To determine national trends in self-reported depressive symptoms. METHOD Depressive symptoms were assessed using self-reported data on the nine-item Patient Health Questionnaire (PHQ-9), with a total score ≥10 and an individual item score of 2 or 3, indicating greater severity. RESULTS A total of 31,191 individuals contributed PHQ-9 data from 2005 to 2016. The absolute proportion of individuals with total PHQ-9 score ≥10 increased from 6.2% to 8.1%. After adjustment for participant demographic characteristics and comorbid conditions, the odds ratio for high PHQ-9 score at the end versus the beginning of the study interval was 1.27 (95% confidence interval [CI 1.07, 1.50]). Anhedonia, guilt/worthlessness, appetite, and hypoactivity/hyperactivity had the largest increases in individual item risk after adjusting for demographic and comorbid characteristics. CONCLUSIONS There were sizeable increases in the prevalence of self-reported depressive symptoms in the United States over an 11-year period. Further work is needed to understand the reasons for and implications of this increase. However, the results suggest greater efforts should be made by health care providers to screen for depressive symptoms that may warrant further assessment, treatment, or referral to mental health services as needed.INTRODUCTION We determine the level of adherence to the revised Kenya early infant diagnosis (EID) algorithm during implementation of a point-of-care (POC) EID project. METHODS Data before (August 2016 to July 2017) and after (August 2017 to July 2018) introduction of POC EID were collected retrospectively from the national EID database and registers for 33 health facilities. We assessed the number of HIV-infected infants who underwent confirmatory testing and received baseline viral load test and proportion of infants with an initial negative result who had a subsequent test. RESULTS AND DISCUSSION Significantly higher number of infants accessed confirmatory testing (94.2% versus 38.6%; P less then .0001) with POC EID. Baseline viral load test and follow-up testing at 6 months, although higher with POC EID, were not significantly different from the pre-POC EID intervention period. CONCLUSION The POC EID implementation has the potential to increase proportion of infants who receive confirmatory testing, thus reducing the risk of false-positive results.Purpose Interaction of ionizing radiations with cells leads to single- and double-strand breaks (SSBs and DSBs) as well as base lesions of DNA. Employing the Geant4-DNA toolkit, we simulated the transportation of primary alphas and secondary particles in liquid water to study the damage in the form of SSBs and DSBs.Materials and Methods Simulations were performed in a spherical water medium, where we used a B-DNA model and classified the DNA damage and its complexity. We assumed that in a certain vicinity of the DNA volume, energy depositions of more than 17.5 eV or hydroxyl radicals with a chemical-reaction probability of 0.13 would lead to strand breaks.Results The results of 2 to 20 MeV alpha particles showed that more than 65% of the energy-deposition cases within the DNA volume would result in a form of break. The frequency pattern of higher-complexity damage types appeared to peak at higher deposited energies. Conclusion We observed a reasonable agreement in terms of trend and value between our DSB yield results and experimental data. The yield results, as function of LET, suggested independence from particle type and converge to some extent at large LET. This manifests the dominant contribution of secondary electrons.Purpose Radiation risk communication is a critical component of radiation protection and the public's understanding of radiation risks and benefits. Risk communication becomes even more complicated when considering cultural and language dif
