Policy Process Theory for Rural Studies: Navigating Context and Generalization in Rural Policy
Authors: Peterson Holly L. , McBeth Mark K. , Jones Michael D. 
Published: August 2020

Rural studies and policy process literature are ripe for integration due to their interdisciplinary approaches, empirical‐foci, and importance of values, norms, and heuristics. Policy process theory often ignores the important context‐rich variation within the rural and urban distinction, yet offers qualities rural scholars may find useful, like generalizability. This integration would improve both literature by facilitating empirical inquiry. Process theory “lenses” offer internal consistency, a shared research agenda, and applicability in many settings. These qualities encourage sharing and comparing of diverse research findings, thereby advancing common understanding and exploration of the policy process. In illustration of these ideas, this article reviews five policy process frameworks, the Institutional Development and Analysis framework, the Advocacy Coalition Framework, the Social Construction Framework, the Narrative Policy Framework, and the Multiple Streams Approach, extant rural policy process studies, and provides examples of how the literature may be integrated to explore specific research areas and questions.Related ArticlesCrow, Deserai A., Lydia A.

Reputation‐SourcedAuthority and the Prospect of Unchecked Bureaucratic Power
Authors: Bertelli Anthony M. , Busuioc Madalina 
Published: August 2020

AbstractWe explore the democratic implications of a reputational account of bureaucratic authority. While an influential literature has examined the relevance of reputation—and mutual exchange between principals and agents in public organizations generally—the normative implications of these insights have largely escaped scrutiny. We discuss how reputation‐building impacts both the ability and the motivation of principals to oversee administrative policymaking. We argue that reputation‐sourced authority eschews ex ante incentives through the claims‐making and maneuvering of bureaucrats as they develop reputations with audiences. At the same time, it de‐legitimizes ex post oversight because monitoring and compliance must compete both with reputational authority and with resistance from the audiences that are the very sources of such authority.
Effect of Loop Tilting on the Heat Transfer and Pressure Drop in Two-Phase CO2 Based Natural Circulation Loop: An Experimental Study
Authors: Thippeswamy L. R. , Yadav Ajay Kumar 
Published: August 2020

Abstract
The natural circulation loop (NCL) is widely used where the safe and economic heat transfer device is desired. However, the instability associated with the regular change in fluid flow behavior due to the imbalance between friction and buoyant forces is a major disadvantage. One of the erudite solutions to overcome this is to tilt the entire loop by a certain angle, with an inherent penalty in heat transfer and pressure drop. In the present study, experimental studies have been carried out on two-phase carbon dioxide (CO2) based NCL, which has gained popularity because of its compactness and higher heat transfer rate. Pressure drop and heat transfer performance of the loop for various tilt angles (0 deg, 30 deg, and 45 deg) in different planes (XY and YZ planes) have been investigated. Methanol is used as the external fluid in cold and hot heat exchangers in order to maintain low operating temperature in the loop. Results show that the tilting of the loop causes a marginal drop in the heat transfer rate of two-phase CO2 based NCL. Hence, tilting of the loop could be a solution to instability problem without conceding the performance of the loop.

Abstract
Accurate failure criteria play a fundamental role in biomechanical analyses of aortic wall rupture and dissection. Experimental investigations have demonstrated a significant difference of aortic wall strengths in the circumferential and axial directions. Therefore, the isotropic von Mises stress and maximum principal stress, commonly used in computational analysis of the aortic wall, are inadequate for modeling of anisotropic failure properties. In this study, we propose a novel stress-based anisotropic failure criterion with dispersed fiber orientations. In the new failure criterion, the overall failure metric is computed by using angular integration (AI) of failure metrics in all directions. Affine rotations of fiber orientations due to finite deformation are taken into account in an anisotropic hyperelastic constitutive model. To examine fitting capability of the failure criterion, a set of off-axis uniaxial tension tests were performed on aortic tissues of four porcine individuals and 18 human ascending thoracic aortic aneurysm (ATAA) patients. The dispersed fiber failure criterion demonstrates a good fitting capability with the off-axis testing data. Under simulated biaxial stress conditions, the dispersed fiber failure criterion predicts a smaller failure envelope comparing to those predicted by the traditional anisotropic criteria without fiber dispersion, which highlights the potentially important role of fiber dispersion in the failure of the aortic wall. Our results suggest that the deformation-dependent fiber orientations need to be considered when wall strength determined from uniaxial tests are used for in vivo biomechanical analysis. More investigations are needed to determine biaxial failure properties of the aortic wall.

Published: August 2020

ObjectivesGain an overview of expected response rates (RRs) to patient-reported outcome measures (PROMs) in clinical quality registry-based studies and long-term cohorts in order to better evaluate the validity of registries and registry-based studies. Examine the trends of RRs over time and how they vary with study type, questionnaire format, and the use of reminders.DesignLiterature review with systematic search.Data sourcesPubMed, MEDLINE, EMBASE, kvalitetsregistre.no, kvalitetsregister.se and sundhed.dk.Eligibility criteriaArticles in all areas of medical research using registry-based data or cohort design with at least two follow-up time points collecting PROMs and reporting RRs. Annual reports of registries including PROMs that report RRs for at least two time points.Primary outcome measureRRs to PROMs.ResultsA total of 10 articles, 12 registry reports and 6 registry articles were included in the review. The overall RR at baseline was 75%±22.1 but decreased over time. Cohort studies had a markedly better RR (baseline 97%±4.7) compared with registry-based data at all time points (baseline 72%±21.8). For questionnaire formats, paper had the highest RR at 86%±19.4, a mix of electronic and paper had the second highest at 71%±15.1 and the electronic-only format had a substantially lower RR at 42%±8.7. Sending one reminder (82%±16.5) or more than one reminder (76%±20.9) to non-responders resulted in a higher RR than sending no reminders (39%±6.7).ConclusionsThe large variation and downward trend of RRs to PROMs in cohort and registry-based studies are of concern and should be assessed and addressed when using registry data in both research and clinical practice.

Published: August 2020

ObjectivesThe aim of this study was to evaluate whether a single treatment session of acupuncture, when applied in addition to standard treatment for acute low back pain (ALBP), reduces the time to recovery compared with standard treatment alone.DesignA multicentre, randomised, controlled trial.SettingConducted at 11 Norwegian general practitioners’ (GPs’) offices.Participants171 adults aged 20–55 years seeking their GP for ALBP (≤14 days) between March 2014 and March 2017. Patients with secondary back pain and previous sick leave and acupuncture treatment was excluded.InterventionsThe participants were randomised to either the control group (CG) or the acupuncture group (AG) by online software. The CG received standard treatment according to the Norwegian guidelines, while the AG received one session of Western medical acupuncture treatment in addition to standard treatment. The statistician was blinded to group status.Primary and secondary outcome measuresThe primary outcome was median days to recovery. Secondary outcomes were pain intensity, global improvement, back-specific functional status, sick leave, medication and adverse effects.Results185 participants were randomised, 95 in the CG and 90 in the AG. 14 participants did not receive the allocated intervention and 4 were excluded from the analysis. Thus, 167 participants were included in the analysis, 86 in the CG and 81 in the AG. The groups were similar according to baseline characteristics. The median time to recovery was 14 days for the CG and 9 days for the AG, HR 1.37 (95% CI 0.95 to 1.96), (p=0.089). No serious adverse effects were reported.ConclusionsWe did not find any statistically significant reduction in time-to-recovery after a single session of acupuncture for ALBP compared with standard care.Trial registration numberNCT01439412.

ObjectiveColorectal cancer (CRC) ranked second in terms of cancer mortality worldwide. It is associated with a substantial global disease burden. We aimed to examine whether the theory of planned behaviour (TPB) could predict the uptake of faecal immunochemical test to inform novel strategies for enhancing CRC screening participation in population-based programmes.DesignCross-sectional study.SettingsA Hong Kong-based and territory-wide telephone survey was conducted during the study period from October 2017 to November 2018.Participants4800 asymptomatic individuals aged 61–70 years who can communicate in Cantonese were recruited during the survey period. Those who had a history of CRC, chronic bowel inflammation, two or more first-degree relatives with CRC, and received colonoscopy in the past 10 years or faecal occult blood test in the past 5 years were excluded.Outcome measuresThe association between CRC screening uptake and the factors pertinent to TPB was analysed by univariable and multivariable regression models and the mediating effect of intention. We adjusted for age, gender, educational level, marital and working status, as well as household income.ResultsMultivariable regression analysis showed that high perceived behavioural control (adjusted OR (AOR)=12.35, 95% CI 8.21 to 18.60, p<0.001), high intention for CRC screening (AOR=7.86, 95% CI 6.60 to 9.36, p<0.001) and positive attitude towards CRC screening (accuracy and effectiveness: AOR=1.19, 95% CI 1.03 to 1.38, p<0.05; embarrassment and apprehension: AOR=4.27, 95% CI 3.13 to 5.82, p<0.001) were significantly associated with CRC screening uptake. Mediation analysis found that the effect of social norms on screening behaviour was primarily mediated by intention (83.2%), and this indirect, mediated effect accounted for 21.7% to 24.1% of total effects of other constructs in TPB on screening behaviour.ConclusionsThe variables pertinent to TPB could successfully predict CRC screening uptake. Promotion of CRC screening based on interventions that increase perceived behavioural control and behavioural intention could potentially enhance screening uptake. Further studies are needed to establish the cause and effect relationship among these variables and screening uptake, as well as to evaluate the cost-effectiveness of such interventions.

Published: August 2020

BackgroundOverweight and obesity are emerging public health problems in Ethiopia. However, primary study findings on the prevalence of overweight and obesity in Ethiopia are inconsistent. Therefore, this study aimed to estimate the pooled prevalence of overweight and obesity among adults in Ethiopia.MethodsStudies that looked at overweight and obesity among adults were searched from four international databases. The search involved articles published from 1 January 2010 to 10 March 2020. The Cochran’s Q χ2 and the I2 test statistics were used to check heterogeneity among the studies. The funnel plot and Egger’s regression tests were also used to assess the presence of publication bias. Subgroup analysis was performed by residence, study setting, sample size and year of study. Sensitivity analysis was also done to assess the effect of a single study on the pooled estimates. Data analysis was done using STATA V.14 software program.ResultsA total of 16 studies with 19 527 study participants were included in this systematic review and meta-analysis. The estimated pooled prevalence of overweight among adults in Ethiopia was 20.4%, and after adjustment for publication bias with the trim-and-fill analysis, the estimated prevalence rate was changed to 19%. Besides, the estimated pooled prevalence of obesity was 5.4%. The prevalence of overweight was higher, 22.6% in studies published since 2015, 22.4% in studies conducted only in urban settings and 24.4% in studies with small sample size (≤384 participants). Similarly, the prevalence of obesity was 6.9% in studies published since 2015, 6.2% in studies conducted only in urban settings, 6.4% in institution-based settings and 9.6% in studies with small sample size.ConclusionThe prevalence of overweight and obesity is high in Ethiopia compared with previous studies. This needs large scale awareness creation campaigns and situation-based and context-specific prevention strategies.

ObjectiveHub and spoke model has been used across industries to augment peripheral services by centralising key resources. This exercise evaluated the feasibility of whether such a model can be developed and implemented for quality improvement across rural and urban settings in India with support from a network for quality improvement.MethodsThis model was implemented using support from the state and district administration. Medical colleges were designated as hubs and the secondary and primary care facilities as spokes. Training in quality improvement (QI) was done using WHO’s point of care quality improvement methodology. Identified personnel from hubs were also trained as mentors. Both network mentors (from QI network) and hub-mentors (from medical colleges) undertook mentoring visits to their allotted facilities. Each of the participating facility completed their QI projects with support from mentors.ResultsTwo QI training workshops and two experience sharing sessions were conducted for implementing the model. A total of 34 mentoring visits were undertaken by network mentors instead of planned 14 visits and rural hub-mentors could undertake only four visits against planned 18 visits. Ten QI projects were successfully completed by teams, 80% of these projects started during the initial intensive phase of mentoring. The projects ranged from 3 to 10 months with median duration being 5 months.DiscussionVarious components of a health system must work in synergy to sustain improvements in quality of care. Quality networks and collaboratives can play a significant role in creating this synergy. Active participation of district and state administration is a critical factor to produce a culture of quality in the health system.

Published: August 2020

BackgroundCerebral venous sinus stenting is an established treatment for patients with idiopathic intracranial hypertension (IIH), refractory to medical management and with stenotic venous sinus on conventional cerebral venography. Currently, there are no clear guidelines on optimal noninvasive imaging modality for routine post-stenting follow-up. We investigated diagnostic yield of CT venography (CTV) for evaluation of stent patency.MethodsWe reviewed our clinical database of patients with a diagnosis of IIH, who underwent stenting of stenotic transverse or transverse/sigmoid sinus junction. Patients who had follow-up CTVs after more than 30 days were included in the final study group. All CTVs were reviewed by two readers for in-stent thrombosis, extrinsic stent compression, juxta-stent stenosis, and new contralateral venous sinus stenosis. Inter-observer agreement and association of stent patency with clinical outcomes (headache and papilledema) were assessed.ResultsIn all 36 included patients with 38 cerebral venograms for stenting, follow-up CTVs demonstrated adequate opacifications of the venous sinuses and stents for confident evaluation for in-stent thrombosis, extrinsic stent compression, juxta-stent stenosis, and new contralateral venous sinus stenosis, with inter-observer agreement coefficient of 0.7, 1.0, 0.8, and 1.0 respectively. Association between abnormal CTV and higher rates of persistent headache and lower rates of headache improvement/resolution was statistically significant (P-value of 0.01).ConclusionCTV is a reliable noninvasive imaging modality for evaluation of cerebral venous sinuses and stent patency following treatment of idiopathic intracranial hypertension with venous sinus stenting and could be used as a routine follow-up study.

Published: August 2020

BackgroundCricothyrotomy is associated with significant aerosolization that increases the potential risk of infection among healthcare providers. It is important to identify simple yet effective methods to suppress aerosolization and improve the safety of healthcare providers.Methods5 ear, nose and throat and general surgeons used a locally developed hybrid cricothyrotomy simulator with a porcine trachea to test three draping methods to suppress aerosolization during the procedure: an X-ray cassette drape, dry operating room (OR) towels and wet OR towels. The three methods were judged based on three categories: effectiveness of suppression, availability in all healthcare systems and ease of handling.ResultsAll five surgeons performed the procedure independently using each of the three suppression methods. The wet OR towel drape was found to be an effective method to suppress aerosolization, and it did not hinder the surgeons from performing the procedure accurately. This finding was confirmed by using an atomized fluorescein dye injection into the porcine trachea, representing aerosolized material while performing the procedure.ConclusionsWe present a novel intervention using wet towels to suppress aerosolization during cricothyrotomy. Wet towels are cheap and readily available within any healthcare setting regardless of the financial resources available.
Processing of Different Temporal Scales in the Human Brain

Published: August 2020

Abstract
While recalling life events, we reexperience events of different durations, ranging across varying temporal scales, from several minutes to years. However, the brain mechanisms underlying temporal cognition are usually investigated only in small-scale periods—milliseconds to minutes. Are the same neurocognitive systems used to organize memory at different temporal scales? Here, we asked participants to compare temporal distances (time elapsed) to personal events at four different temporal scales (hour, day, week, and month) under fMRI. Cortical activity showed temporal scale sensitivity at the medial and lateral parts of the parietal lobe, bilaterally. Activity at the medial parietal cortex also showed a gradual progression from large- to small-scale processing, along a posterior–anterior axis. Interestingly, no sensitivity was found along the hippocampal long axis. In the medial scale-sensitive region, most of the voxels were preferentially active for the larger scale (month), and in the lateral region, scale selectivity was higher for the smallest scale (hour). These results demonstrate how scale-selective activity characterizes autobiographical memory processing and may provide a basis for understanding how the human brain processes and integrates experiences across timescales in a hierarchical manner.

AbstractTo identify the factors influencing outcome in childhood mature B-cell non-Hodgkin lymphoma and acute leukemia (B-NHL/AL) with central nervous system (CNS) disease (CNS+), we analyzed patients &lt;18 years with newly diagnosed B-NHL/AL registered in 3 Lymphomes Malins B studies in France between 1989 to 2011. CNS+ was diagnosed on fulfillment of ≥1 of the following criteria: any L3 cerebrospinal fluid (CSF) blasts (CSF+), cranial nerve palsy, isolated intracerebral mass but also clinical spinal cord compression, and cranial or spinal parameningeal extension. Two hundred seventeen out of 1690 patients (12.8%) were CNS+. CNS+ was significantly associated with male gender, head/neck locations, Burkitt histology, high initial lactate dehydrogenase (LDH) level, and bone marrow involvement. CSF+ was the most frequent pattern of CNS+ (45%). For the 217 CNS+ patients, the 5-year event-free survival (EFS) and overall survival rates (95% confidence interval) were 81.5% (75.8% to 86.1%) and 83.9% (78.4% to 88.2%), respectively. In multivariate analysis, among CNS+ patients, low EFS was associated with CSF+, high initial LDH level, and poor response to cyclophosphamide, oncovin (vincristine), prednisone prephase. These findings have been considered for patient’s stratification in the international randomized phase 3 trial Inter-B-NHL-ritux 2010 for children and adolescents with high-risk B-NHL/AL with CNS+ CSF+ patients only receiving intensified chemotherapy.
