The Wavelength Papers
Authors: Windhausen Federico 
Published: June 2023

Abstract
What remains of the North American avant-garde of the 1960s and ‘70s? Certainly many more films than filmmakers, but a paper trail as well. Housed in museums, university libraries, film archives, and personal collections across the United States and Canada, a decentralized and ever-expanding set of documents and ephemera is shaping and informing numerous research-based projects in curation, academic scholarship, and film restoration. And yet, in contrast to this contemporary trend, the collected papers of Michael Snow at the Art Gallery of Ontario in Toronto have yet to be explored in depth. A notable exception is Elizabeth Legge's monograph on Snow's Wavelength (1967), which cites some of the notes he kept during the film's conceptualization and production.2 Because the analysis of those notes was not one of Legge's primary objectives, however, her book reproduces only three of the pages in Snow's Wavelength file.
The occasion of Snow's recent passing will doubtless be met by various forms of retrospection, and this small contribution to that extended moment of reflection makes available in print a greater number of the Wavelength files than have previously been published. They represent a rare instance of a canonical avant-garde film's being accompanied by a significant corpus of scribblings, illustrations, and diagrams. This selection, comprising twenty-four pages taken from the filmmaker's unbound notes, introduces some of the themes and questions that Snow was putting to paper during the project's year of gestation. Below, I offer a few remarks on those pages. They are admittedly somewhat arbitrary, but they are intended to bring to light some of the archive's lesser-known revelations.
Southern Hemisphere Storm Tracks and Large-Scale Variability: What Do the Latest Reanalyses Say?
Authors: Campbell Isaac , Renwick James A. 
Published: June 2023

Abstract
In this study, we explore linkages between the monthly mean 500 hPa height field (Z500) and its high-frequency variability over 2–8-day periods, a proxy for Southern Hemisphere storm track activity. We apply maximum covariance analysis to identify leading modes of covariability between the Z500 and high-frequency variance anomalies on monthly and submonthly time scales, using two reanalysis products. We also calculate covariance with indices of large-scale variability [Southern Annular Mode (SAM), El Niño–Southern Oscillation (ENSO), and zonal wave 3 (ZW3)]. We find large-scale circulation patterns emerge as prominent modes of covariability, particularly SAM and ENSO, accounting for 11.1% and 7.8% of covariability on the monthly scale, respectively. The seasonal cycle plays a prominent role in explaining variability in both SAM and ENSO interactions with the storm track. We find that despite a broadly linear response, both SAM and ENSO teleconnections present additional complexities and nonlinearities. Despite strong ZW3 signals in the mean height field, its influence on the high-frequency variance field remains unclear. We conclude the mean height field is most likely strongly linked with high-frequency variance, but interference from other influences may lead to an inconsistent response. We note both fields have an apparent hemispheric response to the SAM, but ENSO has a more regional response and ZW3 a relatively incoherent response. This suggests ENSO and ZW3 patterns depend less on feedbacks between the storm track and the mean height field than the SAM.
ENSO Modulation of Global MJO and Its Impacts on South America
Authors: Fernandes Laís G. , Grimm Alice M. 
Published: June 2023

Abstract
Changes in the Madden–Julian oscillation (MJO) and its impacts on the South American monsoon season during different El Niño–Southern Oscillation (ENSO) states [El Niño (EN), La Niña (LN), neutral (NT)] are analyzed in the global context of the MJO-propagating anomalies of convection and circulation. The background ENSO-related changes influence several aspects of MJO (relative occurrence of phases, propagation, convection, and teleconnections), and therefore modify the MJO impacts on South America (SA), such as precipitation anomalies and frequency of extreme events, as well as their distribution throughout the MJO cycle. Among the changes are the following: 1) a delay in the teleconnection between the central-east Pacific and SA, from MJO phase 8 in LN (MJOLNphase8) to MJO phase1 in EN (MJOENphase1); 2) enhanced MJO convection in the central-east subtropical South Pacific in MJOLNphases7 + 8 and a little farther east in MJOENphases8 + 1, in a region efficient in generating teleconnections that produce rainfall anomalies over central-east SA (CESA), especially the South Atlantic convergence zone (SACZ), strongest one phase earlier in LN (MJOLNphase8) than in EN (MJOENphase1), and a little shifted east in the latter than in the former; 3) enhancement of the extratropical teleconnection and its impacts over the SACZ in both EN and LN (with regard to NT), indicating nonlinear effects on MJO impacts over SA; 4) predominant increase (or reduction) in the frequency of extreme events over SA regions where both ENSO and MJO contribute in the same direction, with the greatest increase over CESA during EN in MJOENphase1 and over Southeast SA (SESA) in MJOENphase3.

Significance Statement
The changes produced by different El Niño–Southern Oscillation background states (neutral, El Niño, La Niña) in the Madden–Julian oscillation (MJO) and its impacts on precipitation over South America (SA) are disclosed for the austral summer monsoon season, when MJO is strongest. The reliability of the results is enhanced by using observed rainfall data. The background states affect MJO propagation, circulation, and convection, producing significant differences in precipitation and extremes over densely populated regions, besides phase shifts of the strongest impacts. The results are relevant to subseasonal prediction, since MJO is a key predictability source, to validate models and describe realistically the impacts over SA in each MJO phase. Models’ skill in simulating these results is assessed in a follow-up work.

Published: June 2023

Background Complex surgeries such as pancreaticoduodenectomies (PD) have been shown to have better outcomes when performed at high-volume centers (HVCs) compared to low-volume centers (LVCs). Few studies have compared these factors on a national level. The purpose of this study was to analyze nationwide outcomes for patients undergoing PD across hospital centers with different surgical volumes. Methods The Nationwide Readmissions Database (2010-2014) was queried for all patients who underwent open PD for pancreatic carcinoma. High-volume centers were defined as hospitals where 20 or more PDs were performed per year. Sociodemographic factors, readmission rates, and perioperative outcomes were compared before and after propensity score-matched analysis (PSMA) for 76 covariates including demographics, hospital factors, comorbidities, and additional diagnoses. Results were weighted for national estimates. Results A total of 19,810 patients were identified with age 66 ± 11 years. There were 6,840 (35%) cases performed at LVCs, and 12,970 (65%) at HVCs. Patient comorbidities were greater in the LVC cohort, and more PDs were performed at teaching hospitals in the HVC cohort. These discrepancies were controlled for with PSMA. Length of stay (LOS), mortality, invasive procedures, and perioperative complications were greater in LVCs when compared to HVCs before and after PSMA. Additionally, readmission rates at one year (38% vs 34%, P < .001) and readmission complications were greater in the LVC cohort. Conclusions Pancreaticoduodenectomy is more commonly performed at HVCs, which is associated with less complications and improved outcomes compared to LVCs.

Published: June 2023

Background: Most randomised controlled trials on advance care planning were conducted in people with advanced, life-limiting illnesses or in institutional settings. There are few studies on its effect in older people living in the community. Aim: To determine the effects of advance care planning in older community dwelling people. Design: The STADPLAN study was a cluster-randomised trial with 12 months follow-up. The complex intervention comprised a 2-days training for nurse facilitators that delivered a formal advance care planning counselling and a written information brochure. Patients in the control group received optimised usual care, that is, provision of a short information brochure. Setting/participants: Home care services in three regions of Germany were randomised using concealed allocation. Care dependent clients of participating home care services, aged 60 years or older, and rated to have a life-expectancy of at least 4 weeks were included. Primary outcome was active participation in care at 12 months, assessed by blinded investigators using the Patient Activation Measure (PAM-13). Results: Twenty-seven home care services and 380 patients took part. Three hundred seventy-three patients were included in the primary analysis ( n = 206 in the intervention and n = 167 in the control group). There was no statistically significant difference between the intervention and control group with regard to the PAM-13 after 12 months (75.7 vs 78.4; p = 0.13). No differences in quality of life, anxiety and depression, advance care planning engagement, and in proportion of participants with advance directives were found between groups. Conclusions: The intervention showed no relevant effects on patient activation or quality of life in community dwelling older persons, possibly indicating the need for more tailored interventions. However, results are limited by a lack of statistical power. Trial registration: German Clinical Trials Register: DRKS00016886

Published: June 2023

Background: School feeding programs (SFP) in low-income countries are designed to provide food to vulnerable school children to create optimal educational and health conditions for learners. Ethiopia scaled up the implementation of SFP in Addis Ababa. Yet, the utility of this program in terms of school absenteeism has not been monitored thus far. Hence, we aimed at evaluating the effect of the SFP on school performance of primary school adolescents in Addis Ababa, Central Ethiopia. Methods: A prospective cohort study was carried out from 2020 to 2021 on SFP-beneficiary (n = 322) and non-SFP beneficiary (n = 322). Logistic regression models were done using SPSS version 24. Results: In logistic regression, unadjusted model (model 1), the school absenteeism of non-school-fed adolescents was higher by 1.84 (adjusted odds ratio [aOR] 0.36, 95% confidence interval [CI] 1.28-2.64) as compared to school-fed adolescents. The odds ratio remained positive after adjusting for age and sex (model 2: aOR 1.84, 95% CI 1.27-2.65), and sociodemographic (model 3: aOR 1.84, 95% CI 1.27-2.67). In the final model, adjusted model 4, health and lifestyle, there was a significant increase in absenteeism of non-school-fed adolescents (model 4: aOR 2.37, 95% CI 1.54-3.64). The likelihood of absenteeism in female increase by 2.03 (aOR 2.03, 95% CI 1.35-3.05), whereas being in a low tertile wealth index family decreases absenteeism by (aOR 0.51, 95% CI 0.32-0.82). School feeding was negatively associated with school absenteeism. Conclusions: The findings imply the need for strengthening school feeding programs.

Published: June 2023

Background Research suggests that integrase strand transferase inhibitor use can lead to weight gain, and data from sub-Saharan countries are limited. This study investigated changes in weight in Namibians switched from tenofovir DF/emtricitabine/efavirenz (TEE) to tenofovir DF/lamivudine/dolutegravir (TLD). Methods Longitudinal, retrospective, and quantitative study from outpatient records of Namibians living with HIV/AIDS switched from efavirenz-to dolutegravir-based regimen at four clinics. A linear mixed effects model predicting weight 6 months prior to the switch, time of the switch, and at 6, 12-, and 18-months post-switch was run. A second analysis comparing change in weights between males and females was also run. Results 242 patients switched from TEE to TLD. Compared to patient weight at the time of the switch, weights were significantly higher at 6 (+0.9 kg, p = 0.004), 12 (+1.7 kg, p < 0.001), and 18 months (+1.4 kg, p < 0.001) post-switch. There was no significant weight change for males, but females had a significant weight gain at 12 (+1.58 kg, p = 0.012) and 18 months (+1.49 kg, p = 0.024) post switch. Conclusions Females living with HIV in Namibia gain weight when switched from TEE to TLD. Clinical implications on the development of cardiometabolic complications is unclear and mechanisms by which the weight gain occurs are unknown.

Published: June 2023

Background The aggregation of tau hyperphosphorylation (p-tau) into neurofibrillary tangles (NFT) is a hallmark in the histopathology of Alzheimer’s disease (AD). Our previous experiments found that β-asarone could prevent injury of PC12 cells induced by A 1–42, but could it fight cell damage of p-tau induced by okadaic acid (OA) is poorly understood. Objectives The emphasis of this study lies in β-asarone’s therapeutical effect on p-tau inhibition stimulated by OA. Materials and Methods 175 nmol OA was used to establish AD cells. Cell viability rate and cell toxicity were evaluated by the CCK-8 kit and LDH kit, respectively. The p-tau, Aβ42, β-secretase, and protein phosphatase 2A (PP2A) were examined by ELISA. Proteins closely related to the pathogenesis of AD are involved p-tau, Beclin-1, p-Akt, and p-mTOR were analyzed by western-blotting and immunofluorescence detection. Results The results revealed that β-asarone enhanced cell viability induced by OA in a dose-dependent manner. Moreover, compared to the OA model, p-tau, Aβ42, β-secretase, and Beclin-1 were reduced, while PP2A, p-Akt, and p-mTOR increased after treatment with β-asarone. Conclusion All data suggested that β-asarone decreased p-tau, Aβ42, and β-secretase levels, and activated PP2A levels by inhibiting Beclin-1-dependent autophagy in OA model cells, involving Akt/mTOR/Beclin-1 pathway.

Authors: Aluri James , Goodman David , Antshel Kevin , Mojtabai Ramin 
Published: June 2023

Objective: To assess whether prevalence of treatment for ADHD varies by location of mental healthcare among US college students aged 18 to 25 with professionally diagnosed ADHD. Method: Our analysis uses cross-sectional data from the National College Health Assessment (NCHA) and evaluated the relationship between types of care received and location of mental health services received in the past year (dichotomized into “use of any on-campus services” and “use of off-campus services only”). We generated unadjusted and adjusted logistic regression models of each type of treatment. Results: Students who reported receiving mental healthcare on campus were less likely to receive any medication (aOR 0.66, 95% CI [0.60, 0.72]), any therapy (aOR 0.82, 95% CI [0.75, 0.89]), and any medication or therapy for ADHD (aOR 0.63, 95% CI [0.57, 0.70]). Conclusion: Future research should evaluate the causes of lower prevalence of ADHD treatment among students receiving mental healthcare from campus-based clinics.
Pornography Use and Violence: A Systematic Review of the Last 20 Years
Authors: Mestre-Bach Gemma , Villena-Moya Alejandro , Chiclana-Actis Carlos 
Published: June 2023

Pornography use is one of the factors that has been proposed to be associated with violence. We aimed to explore the literature of the last 20 years, with the objective of understanding the possible association between pornography use and violence. Two electronic databases (PsycINFO/PsycARTICLES and PubMed/Medline) were used. We included members of the general population, of any sex, age, and sexual orientation, who were direct users of pornography or have a partner who uses pornography. Only studies with pornography use and violence assessments, and that specifically evaluated the association between both factors, were included. In all, 59 studies met the inclusion criteria. An association between pornography use and nonsexual violence seems to exist, although the causality of this association remains unclear. Heterogeneity of results exists regarding the association between pornography use and intimate partner sexual assault and coercion: some studies have failed to demonstrate this association, while others have observed it partially or significantly. Contradictory results have also been observed when examining the association between pornography use, rape myths, and other beliefs/attitudes. The main limitation is the heterogeneity in the conceptualization of both constructs (pornography and violence). Multiple theoretical models, methodologies, and categorizations have been used in the studies, complicating the comparability of the findings. The association between different types of violence and pornography use requires further in-depth research to better understand the specific link between both constructs. CRD42021259874.

Background: Peripheral artery disease (PAD) guidelines recommend revascularization only for patients with lifestyle-limiting claudication that is refractory to goal-directed medical therapy (class IIA, level of evidence A). However, real-world invasive treatment patterns and predictors of revascularization in patients with symptomatic lower-extremity PAD are still largely unknown. Aim: We aimed to examine rates, patient-level predictors, and site variability of early revascularization in patients with new or worsening PAD symptoms. Methods: Among patients with new-onset or recent exacerbation of PAD in the 10-center Patient-centered Outcomes Related to TReatment practices in peripheral Arterial disease: Investigating Trajectories (PORTRAIT) study enrolled between June 2011 and September 2015, we classified early revascularization (endovascular or surgical) as procedures being performed within 3 months of presentation. Hierarchical logistic regression was used to identify patient characteristics associated with early revascularization. Variability across sites was estimated using the median odds ratio (OR). Results: Among 797 participants, early revascularization procedures were performed in 224 (28.1%). Rutherford class 3 (vs Rutherford class 1; OR=1.86, 95% confidence interval [CI] 1.04–3.33) and having lesions in both iliofemoral and below-the-knee arterial segments (vs below the knee only; OR=1.75, 95% CI: 1.15–2.67) were associated with a higher odds of revascularization. Longer PAD duration >12 months (vs 1–6 months; OR=0.50, 95% CI: 0.32–0.77), higher ankle-brachial index scores (per 0.1 unit increase; OR=0.86, 95% CI: 0.78–0.96), and higher Peripheral Artery Questionnaire Summary scores (per 10 unit increase; OR=0.89, 95% CI: 0.80–0.99) were associated with a lower odds of revascularization. The raw rates for revascularization in different sites ranged from 6.25% to 66.28%, and the median OR was 1.88, 95% CI: 1.38–3.57. Conclusions: About 1 in 3 patients with symptomatic PAD received early revascularization. A more extensive disease and symptom burden were the main predictors of receiving early revascularization in PAD. There was significant site variability in revascularization patterns, and further studies will better understand the source of this variability and optimal selection criteria for early revascularization. Clinical Impact Real world patterns and predictors of early revascularization in peripheral artery disease are not well understood. In this retrospective analysis of the POTRAIT study, about 1 out of 3 patients with PAD symptoms received early revascularization, with significant site variability. A more extensive disease and symptom burden were the main predictors of receiving early revascularization in PAD.

Backgrounds: Nursing is the key group to provide healthcare services, and it is easy for nursing staff to develop mental health problems. Aims: The study aimed to evaluate prevalence of psychological symptoms in nurses working in an intensive care unit (ICU) and the inter-relationship of associations of psychological symptoms using network analysis. Methods: This study is a cross-sectional design study. The Chinese version of the Symptom Check List-90 (SCL-90) was used to measure the psychological status of ICU nurses. The network structure of psychological symptoms was characterised, and indices of ‘Expected influence’ were used to identify symptoms central to the network. Network stability was examined using a case-dropping bootstrap procedure. Results: Multiple logistic regression analysis found those who had worked more than 15 years were less likely to experience positive psychological symptoms, whereas nurses working in emergency ICU and other ICUs, nurses working in departments with over 16 beds were more likely to develop psychological symptoms. In addition, ‘Anxiety’, ‘Mental degeneration’ and ‘Depression’ were central symptoms in the network. Conclusions: ICU nurses reported a high level of psychological symptoms, which may affect the quality of their work and worsen public health problems.
