Utilization of Screening Mammography in Women Before 50: Cross-Sectional Survey Results from the National Health Interview Survey.

OBJECTIVE: While the American College of Radiology recommends annual screening mammography starting at age 40 years, the US Preventive Services Task Force (USPSTF) recommends that screening mammography in women younger than age 50 years should involve shared- decision making (SDM) between clinicians and patients, considering benefits and potential harms in younger women. Using a nationally representative cross-sectional survey, we aimed to evaluate patient-reported reasons and predictors of screening mammography utilization in this age group. METHODS: Respondents aged 40-49 years from the 2018 National Health Interview Survey (NHIS) without a history of breast cancer were included (response rate 64%). Participants reported sociodemographic variables and reasons they did not engage in mammography screening within the last two years. Multiple variable logistic regression analyses were performed to evaluate the association between sociodemographic characteristics and patient-reported screening mammography use, accounting for complex survey sampling design elements. RESULTS: 1,948 women between the ages of 40-49 years were included. Of this group, (758/1948) 46.6% reported receiving a screening mammogram within the last year, and 1196/1948 (61.4%) reported receiving a screening mammogram within the last two years. The most common reasons for not undergoing screening included: "No reason/never thought about it" 744/1948 (38.2%), "Put it off" 343/1948 (17.6%), "Didn't need it" 331/1948 (16.9%), "Doctor didn't order it" 162/1948 (8.3%), and "I'm too young" 63/1948 (5.3%). Multiple variable analyses demonstrated that lack of health insurance was the strongest predictor of mammography non-engagement (p< 0.001). CONCLUSION: Deficits in shared- decision-making in women younger than 50 years related to mammography utilization exist. Radiologists may be key in addressing this issue among ambulatory care providers and patients, educating about the benefits and harms of screening younger women, particularly in racial/ethnic minorities and uninsured patients, who experience additional barriers to care and SDM discussions.

[Impact of social network use on anorexia and bulimia in female adolescents: a systematic review].

Systematic review of published studies on the impact of social networks (SN) use on anorexia and bulimia in female adolescents. We selected articles published over the past 10 years, written in English, Spanish or Portu-guese found in The Cochrane Library Plus, PubMed, WOS, PsycINFO, and Scopus databases and with enough methodological quality. Nine studies were included in this review with a sample of 2,069 adolescents; 75.3% were female, mean age was 18 years, and mostly used Facebook and Instagram. Despite some positive aspects, SNs promote beauty standards in terms of thinness, allow comparisons between peers increasing concerns about weight, and create spaces that encourage anorexia and bulimia. Therefore, SN use plays a role in the development of eating disorders. The promotion of extreme thinness in girls makes this population more vulnerable.

Influencia de las redes sociales sobre la anorexia y la bulimia en las adolescentes: una revisión sistemática / Impact of social network use on anorexia and bulimia in female adolescents: a systematic review

Se realizó una revisión sistemática de los estudios que han investigado la influencia de las redes sociales (RRSS) sobre las adolescentes en relación a la anorexia y bulimia nerviosa. Se seleccionaron artículos publicados en inglés, español o portugués en las bases de datos The Cochrane Library Plus, PubMed, WOS, PsycINFO y Scopus en los diez últimos años, con calidad suficiente. Se incluyeron nueve estudios con una muestra de 2.069 adolescentes (75,3% mujeres) de edad media 18 años, que utilizaban principalmente Facebook e Instagram. A pesar de algunos aspectos positivos, las RRSS promueven cánones de belleza basados en la delgadez, permiten la comparación entre iguales incrementando la preocupación por el peso, y crean espacios que fomentan los trastornos de la conducta alimentaria. Por tanto, las RRSS influyen en el desarrollo de trastornos de la conducta alimentaria y al promover la extrema delgadez en las chicas, las hace más vulnerables.(AU)

Influence of water on the microscopic dynamics of 1-butyl-3-methylimidazolium tetrafluoroborate studied by means of quasielastic neutron scattering.

We present a systematic study on the effect of water on the microscopic dynamics of 1-butyl-3-methylimidazolium tetrafluoroborate by means of quasielastic neutron scattering. By mixing the ionic liquid with either heavy or light water, the different contributions to the quasielastic broadening could be identified and treated separately. This study was performed at room temperature, which is more than 15 °C above the demixing line. Our results show that even small amounts of water accelerate the diffusion mechanisms considerably. While samples with small water percentage reveal a diffusion process confined within ionic liquid nanodomains, an admixture of more than 15 wt. % water relieves the confinement. Furthermore, the presence of two water species was identified: one behaving as free water, whereas the other was interpreted as a component bound to the ionic liquid motion. Based on the fact that water preferentially binds to the BF4 anion, which itself has a negligible contribution to the scattered intensity, our experiments reveal unprecedented information about the microscopic anion dynamics.

[Non-drug treatments for chronic non-malignant pain: patients' perceptions].

BACKGROUND: The prevalence of chronic pain in Spain is 17%. There is a need for more scientific data on non-drug treat-ments that can be effectively used to treat chronic pain. The aim of this study is to analyze how patients with chronic non-malignant pain perceive non-drug approaches. METHOD: Mixed, descriptive and phenomenological study. Nineteen patients enrolled in a workshop on pain management and non-drug treatments that consisted of four sessions (one session a week). Each session lasted four hours. The patients then participated in a reflective writing activity about their personal experiences. Data from this activity was then ana-lyzed. Atlas.ti 8 software was used for the qualitative data analysis. RESULTS: Sixteen participants tried an alternative therapy and fourteen assessed its benefits. The participants' expecta-tions were divided into three groups of similar size: relief from physical pain, emotional pain management and tools for use in daily life. All the participants were satisfied with the workshop. Perceived personal benefits were better pain and sleep management, reduced fatigue, reduced drug consumption; a more positive approach to life, better mood, more positive energy, more motivation and improved capacity to cope. CONCLUSIONS: The participants commented that the workshop had helped them to reduce pain levels and consume to fewer analgesics, and had reduced other symptoms associated with chronic disease, thus improving their perceived health. They also expressed great satisfaction with the organization and teachers.

Propagative Oscillations in Codirectional Polariton Waveguide Couplers.

We report on novel exciton-polariton routing devices created to study and purposely guide light-matter particles in their condensate phase. In a codirectional coupling device, two waveguides are connected by a partially etched section that facilitates tunable coupling of the adjacent channels. This evanescent coupling of the two macroscopic wave functions in each waveguide reveals itself in real space oscillations of the condensate. This Josephson-like oscillation has only been observed in coupled polariton traps so far. Here, we report on a similar coupling behavior in a controllable, propagative waveguide-based design. By controlling the gap width, channel length, or propagation energy, the exit port of the polariton flow can be chosen. This codirectional polariton device is a passive and scalable coupler element that can serve in compact, next generation logic architectures.

Effectiveness of a On-site Medicalization Program for Nursing Homes With COVID-19 Outbreaks.

BACKGROUND: Nursing homes are highly vulnerable to the occurrence of COVID-19 outbreaks, which result in high lethality rates. Most of them are not prepared to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. METHOD: A coordinated on-site medicalization program (MP) in response to a sizeable COVID-19 outbreak in 4 nursing homes was organized, with the objectives of improving survival, offering humanistic palliative care to residents in their natural environment, and reducing hospital referrals. Ten key processes and interventions were established (provision of informatics infrastructure, medical equipment, and human resources, universal testing, separation of "clean" and "contaminated" areas, epidemiological surveys, and unified protocols stratifying for active or palliative care approach, among others). Main outcomes were a composite endpoint of survival or optimal palliative care (SOPC), survival, and referral to hospital. RESULTS: Two hundred and seventy-two of 457 (59.5%) residents and 85 of 320 (26.5%) staff members were affected. The SOPC, survival, and referrals to hospital occurred in 77%, 72.5%, and 29% of patients diagnosed before the start of MP, with respect to 97%, 83.7%, and 17% of those diagnosed during the program, respectively. The SOPC was independently associated to MP (OR = 15 [3-81]); and survival in patients stratified to active approach, to the use of any antiviral treatment (OR = 28 [5-160]). All outbreaks were controlled in 39 [37-42] days. CONCLUSIONS: A coordinated on-site MP of nursing homes with COVID-19 outbreaks achieved a higher SOPC rate, and a reduction in referrals to hospital, thus ensuring rigorous but also humanistic and gentle care to residents.

Death risk stratification in elderly patients with covid-19. A comparative cohort study in nursing homes outbreaks.

Elderly people are more severely affected by COVID-19. Nevertheless scarce information about specific prognostic scores for this population is available. The main objective was to compare the accuracy of recently developed COVID-19 prognostic scores to that of CURB-65, Charlson and PROFUND indices in a cohort of 272 elderly patients from four nursing homes, affected by COVID-19. Accuracy was measured by calibration (calibration curves and Hosmer-Lemeshov (H-L) test), and discriminative power (area under the receiver operation curve (AUC-ROC). Negative and positive predictive values (NPV and PPV) were also obtained. Overall mortality rate was 22.4 %. Only ACP and Shi et al. out of 10 specific COVID-19 indices could be assessed. All indices but CURB-65 showed a good calibration by H-L test, whilst PROFUND, ACP and CURB-65 showed best results in calibration curves. Only CURB-65 (AUC-ROC = 0.81 [0.75-0.87])) and PROFUND (AUC-ROC = 0.67 [0.6-0.75])) showed good discrimination power. The highest NPV was obtained by CURB-65 (95 % [90-98%]), PROFUND (93 % [77-98%]), and their combination (100 % [82-100%]); whereas CURB-65 (74 % [51-88%]), and its combination with PROFUND (80 % [50-94%]) showed highest PPV. PROFUND and CURB-65 indices showed the highest accuracy in predicting death-risk of elderly patients affected by COVID-19, whereas Charlson and recent developed COVID-19 specific tools lacked it, or were not available to assess. A comprehensive clinical stratification on two-level basis (basal death risk due to chronic conditions by PROFUND index, plus current death risk due to COVID-19 by CURB-65), could be an appropriate approach.

Outcomes of the PIRASOA programme, an antimicrobial stewardship programme implemented in hospitals of the Public Health System of Andalusia, Spain: an ecologic study of time-trend analysis.

OBJECTIVES: Inappropriate antimicrobial use favours the spread of resistance, and multidrug-resistant microorganisms (MDR) are currently of major concern. Antimicrobial stewardship programmes (ASPs) are essential for improving antibiotic use in hospitals. However, their impact on entire healthcare systems has not been thoroughly assessed. Our objective was to provide the results of an institutionally supported ASP involving 31 public hospitals in Andalusia, Spain. METHODS: We designed an ecologic time-series study from 1 January 2014 to 31 December 2017. Quarterly, data on indicators were collected prospectively, and feedback reports were provided. PIRASOA is an ongoing clinically based quality-improvement programme whose key intervention is the educational interview, regular peer-to-peer interventions between advisors and prescribers to reinforce the appropriate use of antibiotics. Seventy-two indicators were monitored to measure prescribing quality (inappropriate treatments), antimicrobial consumption (defined daily doses per 1000 occupied bed-days), incidence density of MDR per 1000 occupied bed-days and crude mortality rate associated with bloodstream infections. We used Joinpoint regression software to analyse the trends. RESULTS: The quality of antimicrobial prescribing improved markedly, and the inappropriate treatment rate was significantly lower, with quarterly percentage change (QPC) = -3.0%, p < 0.001. Total antimicrobial consumption decreased (QPC = -0.9%, p < 0.001), specifically carbapenems, amoxicillin/clavulanic acid, quinolones and antifungal agents, whereas antipseudomonal cephalosporin use increased. While the incidence of MDR showed a sustained decreasing trend (QPC = -1.8%; p 0.002), the mortality of patients with bloodstream infections remained stable (QPC = -0.2%, p 0.605). CONCLUSIONS: To date, the PIRASOA programme has succeeded in optimizing the use of antimicrobial agents and has had a positive ecologic result on bacterial resistance at level of an entire healthcare system.

[Screening for Chagas disease in pregnancy and newborns in Andalusia (Spain)]. / Cribado de Chagas en embarazo y neonato en Andalucía (España).

BACKGROUND: To determine the current state of the implementation of Chagas screening in pregnancy and newborns at risk in the eight Andalusian provinces. METHODS: An observational, cross-sectional and descriptive study was carried out through a survey reviewed and validated by experts from the Andalusian Group of Pediatric Infectious Diseases and Immunology. Eighteen pediatric infectious disease specialists from Andalusian referral hospitals (fourteen public and four private) participated. RESULTS: The Chagas screening during pregnancy was known by seventeen specialists (94%), and systema-tically applied in seven hospitals (38.9%) by gynecologists or midwives. The protocol for following-up newborns at risk was known by sixteen specialists (88.9%) and applied in ten hospitals (55.5%), two of which did not study siblings and relatives of these newborns. Only two cases of vertical transmission of Chagas (11.1%) were detected; it happened in two hospitals applying systematically the Chagas screening to pregnant woman at risk, the same ones that also diagnosed two cases in siblings of newborns at risk. CONCLUSION: In Andalusia screening of Chagas disease in pregnant women and newborns at risk is not carried out in a systematic and uniform way in all the reference hospitals, so an underdiagnosis of congenital Chagas disease is highly probable. The training of professionals involved in assisting pregnant women and their offspring, and the unification of the follow-up criteria for newborns at risk would be essential for carrying out both a correct diagnosis and an early treatment of these cases.

[Analysis of the effectiveness of assisted reproduction techniques]. / Análisis de la eficacia de las técnicas de reproducción asistida.

There are a high number of people affected by infertility who require assisted reproduction techniques. For this reason the aim of this review was to analyze the effectiveness of the interventions carried out using these techniques. A systematic peer review was performed on twelve databases. Inclusion criteria were: randomized clinical trials, published between 2011 and 2016, and with a score greater than two on the Jadad scale. The pharmacological interventions that proved effective were the administration of hormones, intrauterine human chorionic gonadotropin, gonadotrophin and dehydroepiandrosterone, and metformin. An effective surgical intervention, endometrial scratching, was identified. No effective non-pharmacological interventions were found. Assisted reproduction techniques show heterogeneity in both the interventions included and effectiveness criteria (pregnancy rate, live birth rate or implantation rate), which makes a unification of criteria necessary.

Do we need new high-risk criteria for surgically treated renal cancer patients to improve the outcome of future clinical trials in the adjuvant setting? Results of a comprehensive analysis based on the multicenter CORONA database.

BACKGROUND: Since there is still an unmet need for potent adjuvant strategies for renal cancer patients with high progression risk after surgery, several targeted therapies are currently evaluated in this setting. We analyzed whether inclusion criteria of contemporary trials (ARISER, ASSURE, SORCE, EVEREST, PROTECT, S-TRAC, ATLAS) correctly identify high-risk patients. METHODS: The study group comprised 8873 patients of the international CORONA-database after surgery for non-metastatic renal cancer without any adjuvant treatment. Patients were divided into potentially eligible high-risk and assumable low-risk patients who didn't meet inclusion criteria of contemporary adjuvant clinical trials. The ability of various inclusion criteria for disease-free survival (DFS) prediction was evaluated by Harrell's c-index. RESULTS: During a median follow-up of 53 months 15.2% of patients experienced recurrence (5-year-DFS 84%). By application of trial inclusion criteria, 24% (S-TRAC) to 47% (SORCE) of patients would have been eligible for enrollment. Actual recurrence rates of eligible patients ranged between 29% (SORCE) and 37% (S-TRAC) opposed to <10% in excluded patients. Highest Hazard Ratio for selection criteria was proven for the SORCE-trial (HR 6.42; p < 0.001), while ASSURE and EVEREST reached the highest c-index for DFS prediction (both 0.73). In a separate multivariate Cox-model, two risk-groups were identified with a maximum difference in 5-year-DFS (94% vs. 61%). CONCLUSION: Results of contemporary adjuvant clinical trials will not be comparable as inclusion criteria differ significantly. Risk assessment according to our model might improve patient selection in clinical trials by defining a high-risk group (28% of all patients) with a 5-year-recurrence rate of almost 40%.

The accumulation of reproductive isolation in early stages of divergence supports a role for sexual selection.

Models of speciation by sexual selection propose that male-female coevolution leads to the rapid evolution of behavioural reproductive isolation. Here, we compare the strength of behavioural isolation to ecological isolation, gametic incompatibility and hybrid inviability in a group of dichromatic stream fishes. In addition, we examine whether any of these individual barriers, or a combined measure of total isolation, is predicted by body shape differences, male colour differences, environmental differences or genetic distance. Behavioural isolation reaches the highest values of any barrier and is significantly greater than ecological isolation. No individual reproductive barrier is associated with any of the predictor variables. However, marginally significant relationships between male colour and body shape differences with ecological and behavioural isolation are discussed. Differences in male colour and body shape predict total reproductive isolation between species; hierarchical partitioning of these two variables' effects suggests a stronger role for male colour differences. Together, these results suggest an important role for divergent sexual selection in darter speciation but raise new questions about the mechanisms of sexual selection at play and the role of male nuptial ornaments.
