Abstract: A complete census of dusty star-forming galaxies (DSFGs) at early epochs is necessary to constrain the obscured contribution to the cosmic star formation rate density (CSFRD) however, DSFGs beyond z ∼ 4 are both rare and hard to identify from photometric data alone due to degeneracies in submillimeter photometry with redshift. Here, we present a pilot study obtaining follow-up Atacama Large Millimeter Array (ALMA) 2 mm observations of a complete s le of 39 850 μ m-bright dusty galaxies in the SSA22 field. Empirical modeling suggests 2 mm imaging of existing s les of DSFGs selected at 850 μ m—1 mm can quickly and easily isolate the “needle in a haystack” DSFGs that sit at z 4 or beyond. Combining archival submillimeter imaging with our measured ALMA 2 mm photometry (1 σ ∼ 0.08 mJy beam −1 rms), we characterize the galaxies’ IR spectral energy distributions (SEDs) and use them to constrain redshifts. With available redshift constraints fit via the combination of six submillimeter bands, we identify 6/39 high- z candidates each with % likelihood to sit at z 4, and find a positive correlation between redshift and 2 mm flux density. Specifically, our models suggest the addition of 2 mm to a moderately constrained IR SED will improve the accuracy of a millimeter-derived redshift from Δ z /(1 + z ) = 0.3 to Δ z /(1 + z ) = 0.2. Our IR SED characterizations provide evidence for relatively high-emissivity spectral indices (〈 β 〉 = 2.4 ± 0.3) in the s le. We measure that especially bright ( S 850 μ m 5.55 mJy) DSFGs contribute ∼10% to the cosmic-averaged CSFRD from 2 z 5, confirming findings from previous work with similar s les.

Abstract: Asthma and atopic dermatitis (AD) are chronic allergic conditions, along with allergic rhinitis and food allergy and cause high morbidity and mortality both in children and adults. This study aims to evaluate the global, regional, national, and temporal trends of the burden of asthma and AD from 1990 to 2019 and analyze their associations with geographic, demographic, social, and clinical factors. Using data from the Global Burden of Diseases (GBD), Injuries, and Risk Factors Study 2019, we assessed the age‐standardized prevalence, incidence, mortality, and disability‐adjusted life years (DALYs) of both asthma and AD from 1990 to 2019, stratified by geographic region, age, sex, and socio‐demographic index (SDI). DALYs were calculated as the sum of years lived with disability and years of life lost to premature mortality. Additionally, the disease burden of asthma attributable to high body mass index, occupational asthmagens, and smoking was described. In 2019, there were a total of 262 million [95% uncertainty interval (UI): 224–309 million] cases of asthma and 171 million [95% UI: 165–178 million] total cases of AD globally age‐standardized prevalence rates were 3416 [95% UI: 2899–4066] and 2277 [95% UI: 2192–2369] per 100,000 population for asthma and AD, respectively, a 24.1% [95% UI: −27.2 to −20.8] decrease for asthma and a 4.3% [95% UI: 3.8–4.8] decrease for AD compared to baseline in 1990. Both asthma and AD had similar trends according to age, with age‐specific prevalence rates peaking at age 5–9 years and rising again in adulthood. The prevalence and incidence of asthma and AD were both higher for in iduals with higher SDI however, mortality and DALYs rates of in iduals with asthma had a reverse trend, with higher mortality and DALYs rates in those in the lower SDI quintiles. Of the three risk factors, high body mass index contributed to the highest DALYs and deaths due to asthma, accounting for a total of 3.65 million [95% UI: 2.14–5.60 million] asthma DALYs and 75,377 [95% UI: 40,615–122,841] asthma deaths. Asthma and AD continue to cause significant morbidity worldwide, having increased in total prevalence and incidence cases worldwide, but having decreased in age‐standardized prevalence rates from 1990 to 2019. Although both are more frequent at younger ages and more prevalent in high‐SDI countries, each condition has distinct temporal and regional characteristics. Understanding the temporospatial trends in the disease burden of asthma and AD could guide future policies and interventions to better manage these diseases worldwide and achieve equity in prevention, diagnosis, and treatment.
