The Diurnal Temperature Range in CMIP6 Models: Climatology, Variability, and Evolution
Authors: Wang Kang , Clow Gary D. 
Published: August 2020

AbstractThe diurnal temperature range (DTR) is an identifiable and sensitive indicator of the synchronicity of changes in diurnal temperature extrema, but capturing DTR dynamics is challenging for climate models. This study investigates the climatology, variability, and changes of DTR in recent models participating in phase 6 of the Coupled Model Intercomparison Project (CMIP6). The results show that the CMIP6 models underestimate DTR climatology relative to observations. Most individual models overestimate December–February variability, particularly at high latitudes of the Northern Hemisphere. The models show substantially different changes over land surfaces and do not fully capture the observed spatiotemporal evolution of DTR. Large intermodel differences seem to be controlled by daily minimum air temperature. In the Northern Hemisphere, precipitation and cloud longwave and shortwave radiative effects appear to make important contributions to the intermodel discrepancies. Evaporative fraction is an important factor contributing to the intermodel differences in DTR during the summer in the Northern Hemisphere. In general, CMIP6 models have not improved their ability to simulate temporal DTR changes in a consistent way over the entire analysis period (1901–2005) relative to their CMIP5 counterparts. For periods of rapid DTR decline (e.g., 1951–80) CMIP6 models are typically better than the CMIP5 versions at simulating DTR, whereas for other periods CMIP6 models underperform their CMIP5 counterparts.

Published: August 2020

AbstractSevere local storm (SLS) activity is known to occur within specific thermodynamic and kinematic environments. These environments are commonly associated with key synoptic-scale features—including southerly Great Plains low-level jets, drylines, elevated mixed layers, and extratropical cyclones—that link the large-scale climate to SLS environments. This work analyzes spatiotemporal distributions of both extreme values of SLS environmental parameters and synoptic-scale features in the ERA5 reanalysis and in the Community Atmosphere Model, version 6 (CAM6), historical simulation during 1980–2014 over North America. Compared to radiosondes, ERA5 successfully reproduces SLS environments, with strong spatiotemporal correlations and low biases, especially over the Great Plains. Both ERA5 and CAM6 reproduce the climatology of SLS environments over the central United States as well as its strong seasonal and diurnal cycles. ERA5 and CAM6 also reproduce the climatological occurrence of the synoptic-scale features, with the distribution pattern similar to that of SLS environments. Compared to ERA5, CAM6 exhibits a high bias in convective available potential energy over the eastern United States primarily due to a high bias in surface moisture and, to a lesser extent, storm-relative helicity due to enhanced low-level winds. Composite analysis indicates consistent synoptic anomaly patterns favorable for significant SLS environments over much of the eastern half of the United States in both ERA5 and CAM6, though the pattern differs for the southeastern United States. Overall, our results indicate that both ERA5 and CAM6 are capable of reproducing SLS environments as well as the synoptic-scale features and transient events that generate them.

Published: August 2020

AbstractReliable reanalysis products can be exploited to drive mesoscale numerical models and generate high-resolution reconstructions of high-impact weather events. Within this framework, regional weather and climate models may greatly benefit from the recent release of the ERA5 product, an improvement to the ERA-Interim dataset. In this study, two different convection-permitting models driven by these two reanalysis datasets are used to reproduce three heavy precipitation events affecting a Mediterranean region. Moreover, different sea surface temperature (SST) initializations are tested to assess how higher-resolution SST fields improve the simulation of high-impact events characterized by strong air–sea interactions. Finally, the coupling with a distributed hydrological model allows evaluating the impact at the ground, specifically assessing the possible added value of the ERA5 dataset for the high-resolution simulation of extreme hydrometeorological events over the Calabria region (southern Italy). Results, based on the comparison against multiple-source precipitation observations, show no clear systematic benefit to using the ERA5 dataset; moreover, intense convective activity can introduce uncertainties masking the signal provided by the boundary conditions of the different reanalyses. The effect of the high-resolution SST fields is even more difficult to detect. The uncertainties propagate and amplify along the modeling chain, where the spatial resolution increases up to the hydrological model. Nevertheless, even in very small catchments, some of the experiments provide reasonably accurate results, suggesting that an ensemble approach could be suitable to cope with uncertainties affecting the overall meteo-hydrological chain, especially for small catchments.

Published: August 2020

Objectives The highest rates of surgical site infections (SSIs) are associated with colorectal operations (up to 30%). A sentinel paper showed that the use of intravenous (IV) cefazolin and metronidazole was associated with decreased rates of SSI compared with cefoxitin (6% vs 13%). We reviewed the association of SSI with prophylactic antibiotic choice. We specifically investigated the regimens of ceftriaxone and metronidazole IV, cefoxitin IV, or ertapenem. Methods We conducted a retrospective review of 532 colon surgeries between 2016 and 2018. Inclusion criteria were patients 18-89 years of age undergoing elective colon surgery who received ceftriaxone/metronidazole, cefoxitin, or ertapenem for prophylaxis. All emergent cases were excluded. This resulted in 241 elective colon cases for review. The primary endpoint was to determine if the use of ceftriaxone/metronidazole decreased the rate of SSI. Results In total, there were 241 elective colon cases with 21 SSI. We compared SSI rates in the ceftriaxone/metronidazole group to those patients receiving either cefoxitin or ertapenem (4.5% vs 12.2%; P = .035). We then compared SSI in ceftriaxone/metronidazole to SSI in cefoxitin (4.5% vs 10%; P = .13). Finally, we compared SSI in the ceftriaxone/metronidazole group to SSI in the ertapenem group (4.5% vs 14%; P = .03). Comorbidities and underlying factors were similar across all antibiotic groups. Conclusion In our experience, the use of ceftriaxone/metronidazole is associated with a decreased SSI rate. Furthermore, ceftriaxone/metronidazole use is superior to the use of ertapenem, with a trend toward superiority over cefoxitin. Based on this study, we recommend ceftriaxone/metronidazole as antibiotic prophylaxis for elective colon surgery.
The Effects of Residential Mobility on Criminal Persistence and Desistance during the Transition to Adulthood
Authors: Widdowson Alex O. , Siennick Sonja E. 
Published: August 2020

Objectives: Prior research has documented that residential mobility has the potential to trigger both criminal persistence and desistance, with frequent moving often predicting persistence and long-distance moving predicting desistance. However, less work has considered this possibility during the transition to adulthood. To address this shortcoming, we assessed the effects of different residential moves on offending during this period in the life course. Methods: Using 15 waves of data from the National Longitudinal Survey of Youth 1997 Cohort, a sample of youth followed from ages 12 to 32, we used mixed-effects models to examine whether frequent moving, between-county moves (a proxy for long-distance), and moving distance are associated with within-individual change in self-reported offending and arrest. Results: Findings indicated that frequent moving was not associated with persistent offending. In addition, individuals who made between-county moves showed significant within-individual reductions in self-reported offending and arrest, with those reductions emerging immediately after the move and persisting over time. Finally, individuals who moved further in distance were more likely to experience reductions in self-reported offending, although any moving distance reduced arrest. Conclusions: A long-distance residential move may serve as a turning point that facilitates reductions in self-reported offending and arrest.

Published: August 2020

Objectives The health profile of Arab American mothers and infants may differ from that of non–Arab American mothers and infants in the United States as a result of social stigma experienced in the historical and current sociopolitical climate. The objective of our study was to compare maternal health behaviors, maternal health outcomes, and infant health outcomes of Arab American mothers and non-Hispanic white mothers in Massachusetts and to assess the role of nativity as an effect modifier. Methods Using data from Massachusetts birth certificates (2012-2016), we conducted adjusted logistic and linear regression models for maternal health behaviors, maternal health outcomes, and infant health outcomes. We used Arab ethnicity as the exposure of interest and nativity as an effect modifier. Results Arab American mothers had higher odds than non-Hispanic white mothers of initiating breastfeeding (adjusted odds ratio [aOR] = 2.61; 95% CI, 2.39-2.86), giving birth to small-for-gestational-age infants (aOR = 1.28; 95% CI, 1.18-1.39), and having gestational diabetes (aOR = 1.31; 95% CI, 1.20-1.44). Among Arab American mothers, non–US-born mothers had higher odds than US-born mothers of having gestational diabetes (aOR = 1.80; 95% CI, 1.33-2.44) and lower odds of initiating prenatal care in the first trimester (aOR = 0.41; 95% CI, 0.33-0.50). In linear regression models, infants born to non–US-born Arab American mothers weighed 42.1 g (95% CI, −75.8 to −8.4 g) less than infants born to US-born Arab American mothers. Conclusion Although Arab American mothers engage in positive health behaviors, non–US-born mothers had poorer maternal health outcomes and access to prenatal care than US-born mothers, suggesting the need for targeted interventions for non–US-born Arab American mothers.

Published: August 2020

Objective Although some studies have reported a higher incidence of HIV infection among non–US-born people than among US-born people, national data on this topic are scarce. We compared the epidemiology of HIV infection between US-born and non–US-born residents of the United States and examined the characteristics of non–US-born people with diagnosed HIV infection by region of birth (ROB). Methods We used a cross-sectional study design to produce national, population-based data describing HIV infection among US-born and non–US-born people. We analyzed National HIV Surveillance System data for people with HIV infection diagnosed during 2010-2017 and reported to the Centers for Disease Control and Prevention (CDC). We compared data on demographic characteristics, transmission risk category, and stage 3 infection (AIDS) classification within 3 months of HIV diagnosis, by nativity and ROB. Results During 2010-2017, 328 317 children and adult US residents were diagnosed with HIV infection and were reported to CDC: 214 973 (65.5%) were US-born, 50 301 (15.3%) were non–US-born, and 63 043 (19.2%) were missing data on country of birth. After adjusting for missing country of birth, 266 147 (81.1%) people were US-born and 62 170 (18.9%) were non–US-born. This group accounted for 15 928 of 65 645 (24.2%) HIV diagnoses among girls and women and 46 242 of 262 672 (17.6%) HIV diagnoses among boys and men. A larger percentage of non–US-born people than US-born people had stage 3 infection (AIDS) at HIV diagnosis (31.2% vs 23.9%). Among non–US-born people with HIV diagnoses, 19 876 (39.5%) resided in the South. Conclusions Characterizing non–US-born people with HIV infection is essential for developing effective HIV interventions, particularly in areas with large immigrant populations.

Published: August 2020

Objective: To investigate the association between genetic polymorphisms and sudden sensorineural hearing loss (SSNHL). Most of the SSNHL cases still remain idiopathic, and several etiopathogenetic hypotheses, including a genetic predisposition, have been proposed. Methods: A literature review was conducted using different databases: Medline/PubMed, EMBASE, and CINAHL, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All databases have been searched from May 2016 to April 2020. Results: Genetic susceptibility could represent a key element in the pathogenesis of SSNHL. A number of genetic polymorphisms related to (1) inner ear microvascular disease and endothelial dysfunction and (2) to inner ear oxidative stress and inflammation have been addressed in the current literature. Conclusions: The potential identification of a genetic profile related to SSNHL could provide a more accurate prognostic evidence of idiopathic SSNHL (ISSNHL), offering to the patients not only early-prevention strategies but eventually information on various inheritance modalities.

Authors: Sun Wei , Wen Wei-Ping , Zhu Xiao-Lin 
Published: August 2020

Objectives: This study was performed to evaluate the significance of intraoperative preservation of the internal branch of the superior laryngeal nerve (ibSLN) during surgery for hypopharyngeal squamous cell carcinoma (HSCC). Methods: Twelve patients with HSCC underwent surgery between January 2017 and December 2018. Sensation in the hypopharyngeal mucosa was tested using a flexible laryngeal endoscope on postoperative day 5. Results: Surgeries were successfully performed in 10 patients with HSCC arising from the internal wall of the pyriform fossa and in 2 patients with HSCC arising from the posterior wall of the hypopharynx. The main trunk of the ibSLN was preserved in all patients. Testing of sensation in the hypopharyngeal mucosa revealed the presence of the cough reflex in all patients. All patients achieved a full normal oral diet at a median of 8.5 days (range, 6-11 days) and removal of the tracheal tube at a median of 10 days (range, 7-12 days). Conclusions: Our results showed that preservation of the ibSLN during surgery for HSCC is feasible and important in the recovery of sensation in the hypopharyngeal mucosa.
The pervasive relevance of COVID-19 within routine paediatric palliative care consultations during the pandemic: A conversation analytic study
Authors: Ekberg Katie , Weinglass Lara , Ekberg Stuart , Danby Susan , Herbert Anthony 
Published: August 2020

Background: The importance of caring for children with complex and serious conditions means that paediatric palliative care must continue during pandemics. The recent pandemic of Coronavirus Disease 2019 (COVID-19) provides a natural experiment to study health communication during pandemic times. However, it is unknown how communication within consultations might change during pandemics. Aim: This study, a sub-study of a larger project, aimed to examine real-world instances of communication in paediatric palliative care consultations prior to and during the COVID-19 pandemic to understand how clinicians and families talk about the pandemic. Design: Paediatric palliative care consultations prior to, during, and immediately following the initial peak of COVID-19 cases in Australia were video recorded and analysed using Conversation Analysis methods. Setting/participants: Twenty-five paediatric palliative care consultations (including face-to-face outpatient, telehealth outpatient and inpatient consultations) were video recorded within a public children’s hospital in Australia. Participants included 14 health professionals, 15 child patients, 23 adult family members and 5 child siblings. Results: There was a pervasive relevance of both serious and non-serious talk about COVID-19 within the consultations recorded during the pandemic. Topics typical of a standard paediatric palliative care consultation often led to discussion of the pandemic. Clinicians (55%) and parents (45%) initiated talk about the pandemic. Conclusions: Clinicians should not be surprised by the pervasiveness of COVID-19 or other pandemic talk within standard paediatric palliative care consultations. This awareness will enable clinicians to flexibly address family needs and concerns about pandemic-related matters that may impact health and wellbeing.
Popular conspiracy theories in Slovakia and the Czech Republic
Authors: Panczová Zuzana , Janeček Petr 
Published: August 2020

AbstractThe study presents popular conspiracy theories spread within the Czech and Slovak language milieu. Along with the growth in the number of internet portals disseminating this type of texts, their reflection in public opinion is also visible in the way almost every major foreign policy issue or domestic case is commented upon in public internet discussions. The authors seek to identify the narrative and rhetorical sources of conspiracism in these countries since the rise of modern nationalism in the 19th century, focusing on the events accompanying the creation of the common state of the Slovaks and Czechs, the period of the Second World War, the rule of the Communist regime, the events related to the fall of the Iron Curtain and the “Velvet Revolution” in 1989 up to the present. The paper focuses attention on group-shared images of the enemies and on mutual interactions between the interpretations of local events and global conspiracy theories, as well as updates or later reinterpretations of older conspiracy motifs.
Evaluating Culturally Tailored Strategies for Implementing Cognitive Interviewing on Edinburgh Postnatal Depression Scale Among Chinese Immigrant Women

Published: August 2020

Introduction While the Edinburgh Postnatal Depression Scale (EPDS) is a standard clinical screening tool for postpartum depression, it is unclear whether it is culturally appropriate for Chinese immigrant women in the United States. Cognitive interviewing (CI) is a method for evaluating a scale’s cultural appropriateness. However, CI procedures are problematic with Chinese population. This study assesses three culturally tailored strategies for implementing CI to evaluate the Chinese version of the EPDS (C-EPDS). Methodology CI was conducted with 12 participants in the United States. Three culturally tailored strategies—a CI description, a vignette exercise, and debriefing were used. Directed content analysis was used for data analysis. Results The strategies increased participants’ understanding and ability to perform CI procedures, enabling them to discuss postpartum depression. Participants had difficulty responding to several C-EPDS items. Discussion Findings highlight the importance of using culturally tailored strategies for implementing CI to assess cultural appropriateness of clinical screening tools.

Published: August 2020

Objectives: The aim of this study was to investigate whether blood temperature monitoring–guided vascular access intervention could improve dialysis adequacy. Methods: We retrospectively evaluated all patients who received outpatient-based prevalent hemodialysis patients ( n = 84) in our artificial kidney room between January 2019 and October 2019. Through blood temperature monitoring, access blood flow was calculated every month and Kt/ V was calculated every 3 months. The reference point was set at the time of vascular intervention in the patients ( n = 27) who underwent intervention or at the middle of the study period in patients ( n = 57) who did not undergo intervention. The mean blood temperature monitoring–estimated access flow and Kt/ V before and after the reference point were calculated and compared. Results: Among 84 patients, 30 (35.7%) showed access flow rates of <500 mL/min, calculated by blood temperature monitoring during the study period. Twenty-seven patients (32.1%) underwent vascular intervention, of whom 24 (28.6%) showed access flow rates of <500 mL/min, 2 (2.4%) showed weak bruit or thrill incapable of needling, and 1 (1.2%) presented acute occlusion. Six patients (7.1%) whose access flow rates were <500 mL/min refused to undergo intervention. All angiographies in the patients whose access flow rates were <500 mL/min who underwent intervention showed a significant stenosis. The mean change in blood temperature monitoring–estimated access flow and Kt/ V before and after vascular intervention was 483.3 ± 490.6 and 0.19 ± 0.21, respectively, which showed significant differences (all p < 0.05). A weak positive correlation between the mean change in blood temperature monitoring–estimated access flow and Kt/ V was shown in all study patients by Pearson’s correlation analysis ( r = 0.234, p = 0.033). Conclusion: Access flow estimation by blood temperature monitoring might identify candidates who require vascular intervention. Blood temperature monitoring–guided vascular intervention significantly improved access flow and dialysis adequacy.
Recovery processes among young adults treated for alcohol and other drug problems: A five-year follow-up
Authors: Skogens Lisa , von Greiff Ninive 
Published: August 2020

Aim: Studies on recovery from alcohol and other drugs (AOD) among young adults are scarce. In the present study, young adults, previously interviewed with a focus on their recovery process shortly after they completed treatment, were re-interviewed five years later focusing on their recovery process during the last five years in relation to their former AOD problems, other problems and processes of change. Methods: Twenty-one young adults were interviewed: 16 women and five men aged between 25 and 33 years. After transcribing the interviews, the material was analysed thematically. Results: Three overall themes emerged: previous problems, mental illness and the search for identity. The results were discussed in relation to recovery capital, primarily focusing on human and social capital. The results indicate that the group in focus often needs professional support for mental health issues in order to reach a stable recovery. Conclusions: Since the problems described were heterogeneous, this client group might benefit from individual treatment and extended support after treatment. Further, the results indicate that the established period of five years for a stable recovery might need to be extended for young adults.
