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 differences. In the US, many diverse communities face risk communication challenges. We obtained radon testing data to evaluate patterns of radon testing in Allentown, the third largest city in Pennsylvania. Radon exposure is the second leading cause of lung cancer after smoking and is associated with over 21,000 lung cancer deaths in the US annually. It is estimated that 1 in every 15 homes in the US has elevated radon levels above the recommended action level set by the US Environmental Protection Agency. Allentown has some of the highest reported levels of indoor radon in the country, yet only a small portion of the population has tested their homes. This is true particularly among self-identified Hispanics, who make up nearly half of the city's population. This study seeksof non-Hispanics knew that they lived in an area with typically high radon levels. There was a statistically significant association between self-reported ethnicity and radon testing with non-Hispanics (43%) more likely to test their homes for radon than Hispanics (32%).Conclusion Individual and community understanding of the risks of exposure to radiation sources such as radon is dependent upon communication that informs and spurs appropriate action. This study demonstrates the need for culturally appropriate radon risk communication strategies targeted to a Hispanic population. Successful communication will raise awareness and knowledge that can lead to better public health protection.Introduction In May 2019 the International Working Group on the Diabetic Foot (IWGDF) launched their quadrennially updated guidelines on the management of diabetic foot infections (DFIs). Concomitantly, the number of new publications regarding DFI increased.Areas covered The IWGDF committee developed and addressed key questions and produced evidence-based recommendations related to diagnosing and treating DFIs. This narrative review provides an overview of this new guideline and also of other recently published literature in the field of DFIs.Expert opinion The 2019 IWGDF guidelines provide an authoritative, international, evidence-based approach to diagnosing and treating DFIs. The 27 recommendations are supported by systematic reviews of both diagnosis and interventions. Our review of this guideline, along with other recent publications in the field, allows us to offer state-of-the-art guidance for caring for these difficult infections. As the evidence base for management of DFIs remains suboptimal, we need further research to improve the management of DFIs.Background To evaluate the long-term progression of autosomal recessive retinitis pigmentosa (RP) due to mutations in KIZ using multimodal imaging and a quantitative analytical approach.Methods Whole exome sequencing (WES) and targeted capture sequencing were used to identify mutation. Fundus photography, short-wavelength autofluorescence (SW-AF), spectral-domain optical coherence tomography (SD-OCT) imaging, and electroretinography (ERG) were analyzed. Serial measurements of peripheral retinal pigment epithelium (RPE) atrophy area with SW-AF, as well as the ellipsoid zone (EZ) width using SD-OCT were performed.Results Two homozygous variants in KIZ-a c.226C>T mutation as well as a previously unreported c.119_122delAACT mutation-were identified in four unrelated patients. Fundus examination and ERG revealed classic rod-cone dysfunction, and SD-OCT demonstrated outer retinal atrophy with centrally preserved EZ line. SW-AF imaging revealed hyperautofluorescent rings with surrounding parafoveal, mid-peripheral and widespread loss of autofluorescence. The RPE atrophy area increased annually by 4.9%. Mean annual exponential rates of decline for KIZ patients were 8.5% for visual acuity and 15.9% for 30 Hz Flicker amplitude. The average annual reduction distance of the EZ distance was 66.5 μm per year.Conclusions RPE atrophy progresses along with a loss of photoreceptors, and parafoveal RPE hypoautofluorescence is commonly seen in KIZ-associated RP patients. KIZ-associated RP is an early-onset severe rod-cone dystrophy.Background Skin and soft tissue infections (SSTIs) are increasing. Frequent over- and under-treatment has been reported, including non-purulent SSTIs where cases demanding surgery or broad-spectrum therapy often are hard to identify. Our aim was to measure the predictive power of a modified severity score and use it to identify areas of improvement in antimicrobial therapy of non-purulent SSTIs.Methods We prospectively included adult patients admitted to hospital with non-purulent SSTIs. A modified Dundee score at admission was calculated retrospectively, and associations between severity and outcomes were analysed. We evaluated appropriateness of treatment in relation to severity scores, and assessed adverse effects of broad-spectrum therapy.Results We included 200 cases with cellulitis and 19 cases with necrotising soft tissue infections (NSTIs). Thirty-two per cent were categorised as severity class I, 15% as class II, 28% as class III and 25% as class IV (most severe). In class I, 66 out of 69 cases did not have a complicated course. All but one NSTI case were identified by the class IV criteria. Over-treatment was common and mostly seen in class I. Broad-spectrum antibiotics or clindamycin use was associated with an increased risk of diarrhoea. momordin-Ic nmr Prolonged treatment (>14 days) was associated with age, severity and surgery.Conclusions The modified Dundee score proved valuable in identifying those with the lowest risk of complication and the most severe infections, and could serve as a useful clinical tool in the emergency department. Frequent over-treatment and associated adverse effects were confirmed, underscoring the need for improved risk assessment.BACKGROUND Substance misuse remains a public health crisis and contributor to morbidity and mortality. The nursing workforce is not immune to the impacts of substance misuse as rates are thought to mirror those of the general population. Additionally, as substance misuse often begins in adolescence or early adulthood, prevalence of misuse among practicing nurses highlights the fact that students are also at risk. OBJECTIVES The purpose of this study was to examine rates and patterns of substance use and adverse childhood experience (ACE) exposure among nursing students while also examining associations between substance use and ACE exposure. METHOD This study utilizes a cross-sectional and descriptive design through the provision of email surveys to nursing students. Email surveys consisting of the Alcohol Use Disorders Identification Test, the Drug Abuse Screening Tool 10-item survey, the ACE Questionnaire, and a demographic inquiry were distributed via Qualtrics survey software. RESULTS A total of 662 individuals participated in the survey, the majority of whom self-identified as female, were undergraduate students, and were between 18 and 21 years. Moderate- to high-risk alcohol use was identified in 20% of students, while moderate- to high-risk drug use was identified in 3.6% of students. More than half of students endorsed exposure to at least one ACE. Significant associations were found between the Drug Abuse Screening Tool 10-item survey and the ACE Questionnaire. CONCLUSIONS The results of this study have significant implications for nursing educators and must inform groundwork for the development of policies and interventions that are evidence based, nonpunitive, and trauma informed.
