Serial femtosecond crystallography using ultrashort pulses from x-ray free electron lasers (XFELs) enables studies of the light-triggered dynamics of biomolecuies. We used microcrystals of photoactive yellow protein (a bacterial blue light photoreceptor) as a model system and obtained high-resolution, time-resolved difference electron density maps of excellent quality with strong features; these allowed the determination of structures of reaction intermediates to a resolution of 1.6 angstroms. Our results open the way to the study of reversible and nonreversible biological reactions on time scales as short as femtoseconds under conditions that maximize the extent of reaction initiation throughout the crystal.

In territorial systems where quality varies across an area the behavior of individuals is likely to be affected. Territorial aggression is likely linked to territory quality while behaviors like boldness may be linked to novel experiences or disturbance. The goal of this study is twofold: First, to determine whether individual male’s aggression and boldness responses correlate to territory quality (established by historical, 2000-2007, fledging success and clutch sizes) in a natural setting; Second, assess whether territorial individuals in areas disturbed by humans show a difference in behaviors when compared to their more naturally located counterparts. For both questions song playback was used to assay male territorial aggression and flight-initiation-distance was used to assay male boldness. It was found that male song sparrow aggression correlated with historical clutch size but not historical nest success; neither historical clutch size nor nest success correlated with boldness. Results suggest that either more aggressive males are better able to obtain and defend higher quality territories or that males modulate their aggressive behavior according to territory quality. For the second question, a comparison was conducted between aggression and boldness responses in the natural population and males found in the nearby towns of Linesville and Conneaut Lake, PA. Males on human disturbed territories are significantly more aggressive and bolder than males found in natural settings, suggesting more aggressive and/or bolder males are better able to cope with human related stresses or that human disturbance causes a change in male behaviors. Alternatively, given that aggression is correlated with territory quality it may be that human disturbed territories are of a higher quality than the natural territories.

Negative mental health outcomes associated with disaster exposure can increase risks of interpersonal and self-directed violence. However, the link between disaster exposure and increased incidence in violent deaths is not clearly established. The objective of this work is to assess the incidence of violent deaths in non-disaster and disaster periods across five distinct disaster events. This study uses an ecological, quasi-experimental design to assess violent deaths in pre-disaster and disaster periods across five U.S. states (e.g., North Carolina, Oregon, Oklahoma, Wisconsin, and Colorado) with federally declared disasters resulting from natural hazards (e.g., flood, wildfire, tropical cyclone, storms). Deaths recorded in the National Violent Death Reporting System were used to describe violent deaths with injuries occurring three-months prior to and after disaster onset. Poisson regression with population offsets and fixed effects was used to calculate incidence rate ratios for disaster affected and unaffected counties within the same state, comparing violent death rates in disaster periods with non-disaster periods. Most of all deaths were White (80.75%), male (76.87%), and unmarried (65.03%); the median age of decedents was 41.5 years (IQR: 28-55). Overall, the incidence of violent deaths was consistent between disaster and non-disaster periods for both affected (IRR: 0.985; 95% CI: 0.760-1.276) and unaffected counties (IRR: 1.062; 95% CI: 0.975-1.158). Rate ratios were heterogenous but not significant across individual disasters, with only non-suicide and all-cause violent deaths increasing significantly following severe storms and flooding in Wisconsin for counties ineligible for public assistance. The results of this study are consistent with the heterogenous findings on violent deaths and disasters throughout literature. As disasters become more frequent and severe, it is important to further consider the relationship between disaster impacts and negative mental health outcomes, including violent deaths.

Misinformation about reproductive health threatens to harm health outcomes, compromise medical trust, and enable misinformed policy restrictions. In recent years, reproductive health misinformation has proliferated online due to ideological campaigns and limited content moderation for reproductive health topics. Developing evidence-based practices to counter reproductive health misinformation requires an understanding of the content that women are exposed to online, which is currently lacking. This review sought to identify common claims and narratives about reproductive health on social media and the internet that could easily mislead. We performed a narrative review of articles about online reproductive health misinformation, from which we extracted misleading claims and narratives. We conducted a qualitative content analysis to describe the ways in which the claims and narratives could be misleading. We found that potentially misleading claims and narratives about reproductive topics relating to contraception and abortion, fertility, chronic disease, breast cancer, maternal health, and vaccines abound across social media platforms and websites, with 112 identified in total. One-third of this content could mislead by claiming that evidence-based interventions were associated with unattributed risks. Twenty-three percent made medical recommendations that do not align with professional guidelines. Fourteen percent promoted alternative medicine. Smaller numbers of claims and narratives exaggerated risks of medical interventions, discouraged evidence-based interventions, directly undermined medical trust, and proposed inaccurate biological mechanisms. Healthcare professionals can proactively promote evidence-based medical decision-making by increasing their awareness of prominent misleading claims and narratives.

This phase 3 trial showed that persons with noninfectious uveitis who received adalimumab were more likely to have serious adverse events and less likely to have ophthalmic inflammation, uveitic flare, or visual impairment than were those who received placebo. Noninfectious uveitis is a group of vision-threatening diseases that are characterized by intraocular inflammation; it can occur as a syndrome isolated to the eye or in association with a systemic condition. Uveitis has an estimated incidence of 17 to 52 cases per 100,000 person-years 1 and is estimated to cause 10 to 15% of cases of blindness in Western countries. 2 , 3 Glucocorticoids remain the mainstay of therapy despite their well-known ocular and systemic adverse effects. 4 – 6 Thus, there is a large unmet medical need for and a great interest in identifying more effective, glucocorticoid-sparing therapies, ideally targeting specific mediators of the . . .

Background Despite the importance of baseline health data for evidence-informed decision-making, these data are rarely available for displaced populations. At the height of the European refugee crisis, most of those seeking asylum in Europe were from regions with high prevalences of communicable and non-communicable diseases. To create an epidemiologic profile for refugees in camps on mainland Greece, this study assessed the prevalence of 11 communicable and non-communicable diseases among refugees utilizing Médecins du Monde (MdM) in-camp clinics. Methods The proportional morbidity of selected diseases among individuals utilizing MdM services were determined from data collected at refugee camp clinics on mainland Greece from April 2016 - July 2017. Overall and age-specific proportional morbidities were reported. Differences in disease burden among refugees from the largest sending countries - Afghanistan and Syria - were compared using proportional morbidity ratios and 95% confidence intervals. Patterns in results were compared with disease burden estimates in sending countries and with findings from comparable settings. Results Respiratory tract infections (RTIs) were the most prevalent outcome. Among RTIs, upper RTIs were most common, with a proportional morbidity of nearly 40%; throughout the study period, over 46% of children under 18 years had at least one upper RTI consultation. Musculoskeletal conditions (3.64%), were the most prevalent non-communicable outcome, followed by hypertension (2.21%) and asthma (1.28%). Afghans were 31.68% more likely than Syrians to have a consultation for at least one condition (PR: 1.32; 95% CI: 1.25, 1.39). The proportional morbidity of RTIs was comparable to sending countries, but there was a comparatively lower burden of other conditions among refugees than literature estimates from sending countries. Conclusion Refugees utilizing MdM clinics in camps had higher burdens of communicable diseases - predominantly RTIs - relative to non-communicable diseases. Non-communicable disease burdens were comparatively lower than reported prevalences from in-country populations. These findings can be attributed to a range of considerations including differences in demographic profiles between sending countries and refugee populations and missed opportunities for utilizing clinical care. Further investment is needed to capture the health profiles of displaced populations to support evidence-informed decision-making processes in humanitarian emergency responses.
