Oral Ergotamine versus Theophylline as Treatment of Post-dural Puncture Headache (PDPH) in Cesarean Section: A Randomized Clinical Trial
Authors: Manouchehrian Nahid , Jiriaii Nasrin , Sepehri Pourandokht Ghorbani 
Published: September 2023

Introduction:
Post Dural Puncture Headache is (PDPH) a relatively common complication of spinal anesthesia. This study aimed to compare the effect of oral administration of ergotamine and theophylline on PDPH in patients undergoing a cesarean section.

Materials and Methods:
This clinical trial was performed on 60 parturients undergoing cesarean section with PDPH. A tablet of theophylline (100 mg) or methyl ergotamine C (1 mg plus 100 mg caffeine) every 8 hours for 24 hours was administered randomly to patients referred to the hospital with PDPH. Using a checklist, demographic information, history of previous PDPH, number of punctures and intensity, location, and onset time of headache were collected. Intensity and duration of PDPH in the first 24 hours after surgery were the primary outcomes and nausea, vomiting, and vertigo were considered secondary outcomes. The intensity of the headache was assessed using Visual Analog Scale (VAS) before and within the first 24 hours after drug administration.

Results and Discussion:
In both groups, the VAS of headache significantly decreased at 2, 8, and 24 hours after administration of theophylline and ergotamine compared to pre-intervention time (theophylline from 8.6 ± 1.1 to 0.2 ± 0.1 and ergotamine from 8.6 ± 1.5 to 0.4 ± 0.2). However, the intensity of headaches was not different between the two groups at 2, 8, and 24 hours after the intervention. Duration of headache was similar in both groups (15.7 ± 5.9 in the theophylline group versus 17.5 ± 14.2 ergotamine group). In terms of secondary outcomes of nausea, vomiting, and vertigo, both groups were comparable.

Conclusion:
Oral administration of theophylline and ergotamine are similarly effective in reducing PDPH in cesarean sections.

Published: September 2023

Objective:
This study aims to identify barriers and facilitators of HIV/AIDS testing among Latin American immigrant men who have sex with men (MSM).

Methods:
A systematic literature review was conducted using the following databases: MEDLINE via the US National Library of Medicine's PubMed portal; Web of Science (WoS); Cumulative Index to Nursing and Allied Health Literature (CINAHL); Scopus; and Latin American and Caribbean Health Sciences Literature (LILACS).

Results:
Twelve studies were eligible. Overall, the studies indicated that Latin American immigrant MSM have low HIV testing rates. This low testing rate can be influenced by various factors, including knowledge and awareness about HIV; stigma, discrimination, and confidence in health services; barriers to accessing healthcare; type of partnerships and relationships; lack of knowledge about their rights; migration and documentation status; and personal, cultural, and religious beliefs

Conclusion:
Public health interventions aimed at increasing HIV testing among Latin immigrants should directly address the fundamental reasons for not getting tested. This approach is likely to be more successful by taking into account the specific needs and circumstances of Latin immigrant men who have sex with men.

Published: September 2023

Background:
Most hemophiliacs living with HIV are co-infected with HCV. In their clinical practice, the long-term effects of anti-HIV and anti-HCV therapies have not been sufficiently investigated.

Objective:
This study aimed to evaluate changes in HIV RNA and HCV RNA levels and the prognosis in hemophiliacs living with HIV over 24 years in Japan.

Methods:
We used cohort study data of 578 hemophiliacs living with HIV. We analyzed trends in HIV RNA levels between the fiscal years 1997 and 2008 (first follow-up), and trends in HIV RNA and HCV RNA levels between the fiscal years 2009 and 2020 (second follow-up). Mortality rates by HIV RNA and HCV RNA levels were calculated from 11,207 observed person-years and 194 deaths.

Results:
The percentage of HIV RNA levels <400 copies/mL rose in the first period of follow-up, and the percentage of HCV RNA-negative rose in the second period of follow-up. The participants with HIV RNA levels <400 copies/mL had a significantly lower mortality rate than the others, with a ratio of 0.46 in the first period. HCV antibody-positive participants who were HCV RNA-negative had a significantly lower mortality rate than those who were HCV RNA-positive, with a ratio of 0.47 in the second period.

Conclusion:
After the introduction of combination anti-HIV therapy over 24 years in hemophiliacs living with HIV, HIV RNA levels decreased in the first half of this period, resulting in decreased mortality. Additionally, HCV RNA levels decreased in the second half of this study period, resulting in even further decreased mortality.

Effects of Real-Time Pressure Map Feedback on Confidence in Pressure Management in Wheelchair Users With Spinal Cord Injury: Pilot Intervention Study
Authors: Vos-Draper Tamara L , Morrow Melissa M B , Ferguson John E , Mathiowetz Virgil G 
Published: September 2023

Background
Wheelchair users with a spinal cord injury (SCI) are at a high risk for developing pressure injuries (PIs). Performing weight shifts is a primary method of pressure management for PI prevention; however, individuals with SCI may lack confidence in their abilities to perform adequate pressure relief due to their lack of sensation. Real-time seat interface pressure mapping feedback may provide partial substitution for sensory feedback such that an individual’s confidence is improved.

Objective
We aim to examine how confidence for pressure management by wheelchair users with SCI was impacted by providing access to real-time, on-demand seat interface pressure mapping feedback.

Methods
Adults with SCI (N=23) completed self-efficacy questions addressing confidence around 4 factors related to performing weight shifts in this longitudinal, repeated-measures study. We evaluated the impact of providing standard PI prevention education and access to live pressure map feedback on confidence levels for performing weight shifts.

Results
Access to live pressure map feedback while learning how to perform weight shifts resulted in significantly higher confidence about moving far enough to relieve pressure at high-risk areas. Confidence for adhering to the recommended weight shift frequency and duration was not significantly impacted by in-clinic education or use of pressure map feedback. Confidence that performing weight shifts reduces PI risk increased most following education, with slight additional increase when pressure map feedback was added.

Conclusions
Access to live pressure mapping feedback improves confidence about performing weight shifts that relieve pressure when provided in the clinical setting and demonstrates potential for the same in the home. This preliminary exploration of a smartphone-based pressure mapping intervention highlights the value of access to continuous pressure mapping feedback to improve awareness and confidence for managing pressure.

The Peer Deterrent Effect of Whistleblowing on Financial Reporting Aggressiveness
Authors: Zhou Fuzhao , Shen Yinjie , Pitre Terence 
Published: September 2023

SYNOPSIS
Extant literature demonstrates that whistleblowing is associated with changes in the whistleblowing target’s financial reporting. This paper provides compelling evidence that whistleblowing also affects peer firms’ financial reporting. Specifically, we find that industry peers reduce their financial reporting aggressiveness following a whistleblowing allegation. This peer deterrent effect is stronger when the peer firm is geographically closer to the whistleblowing target, when the peer and whistleblowing target share a board member, when the peer is predicted to have a high probability of misstatement, and when the whistleblowing target is larger. Our findings are robust to an array of estimation methods, industry peer definitions, examining windows, and a placebo test.

The Informativeness of Sentiment Types in Risk Factor Disclosures: Evidence from Firms with Cybersecurity Breaches
Authors: Tsang Ronald C. W. , Baldwin Amelia A. , Hair Joseph F. , Affuso Ermanno , Lahtinen Kyre Dane 
Published: September 2023

ABSTRACTThis study examines the degree to which Loughran and McDonald (LM) word lists are informative at the item level of SEC filings, such as risk factors (RF) and management’s discussion and analysis (MDA) disclosures in 10-X reports. In this context, we explore if sentiment types are informative when associated with other material events, namely cybersecurity breaches. Our results support the assertion that sentiment types, beyond positive and negative, are informative at the individual disclosure item level, as tested in the RF and MDA sections. We also find that investors respond to different types of sentiment between RF and MDA. We find an economically significant estimated average economic impact of $469 million/firm. We further contribute to the literature by applying novel statistical methods that advance empirical accounting literature.Data Availability: Data are available from the public sources cited in the text.
The Effect of Mandatory Disclosure Dissemination on Information Asymmetry among Investors: Evidence from the Implementation of the EDGAR System
Authors: Gomez Enrique A. 
Published: September 2023

ABSTRACT
I study the effect of the implementation of the SEC’s EDGAR system on information asymmetry among investors. The SEC adopted EDGAR to decrease acquisition costs of mandatory filings. However, disclosure theory suggests that, even when acquisition costs are low, integration costs (i.e., costs necessary to filter and interpret information signals) may be so high that less sophisticated investors are disadvantaged, relative to their sophisticated peers. Consistent with this theory, I find evidence that EDGAR increased information asymmetries among investors. This result is more pronounced for firms with higher integration costs—i.e., those with more complex filings and filings that have higher information content—as well as for firms with lower analyst coverage. Overall, my results suggest that, although EDGAR lowered acquisition costs for all investors, it also benefited some investors at the expense of others.

New palaeomagnetic data for Palaeoproterozoic AMCG complexes of the Ukrainian Shield
Authors: Bakhmutov V.G. , Mytrokhyn O.V. , Poliachenko I.B. , Cherkes S.I. 
Published: September 2023

A palaeomagnetic study of rocks for two Palaeoproterozoic anorthosite-mangerite-charnockite-granite (AMCG) complexes in the Ukrainian Shield was done to put additional constraints on the interpretation of palaeogeography of Fennoscandia and Volgo-Sarmatia in the Palaeoproterozoic. With this study, 5 sites of Korsun-Novomyrhorod and 3 sites of Korosten AMCG complexes in central and north-western parts of the shield, respectively, were chosen for palaeomagnetic sampling given the geological, modern geochronological and previous palaeomagnetic data. Primary remanent magnetization was isolated on samples of anorthosites, Gabbro, and monzonites within a narrow time interval of U-Pb geochronology dataset of 1.76—1.75 Ga. The palaeomagnetic poles calculated for Korosten and Korsun-Novomyrhorod complexes are almost identical, which indicates that the Volyn and Ingul Domains developed within a single structure of the Ukrainian Shield since at least 1.75 Ga. The new palaeomagnetic pole calculated for all 8 sites (Plat=22.7 °N, Plon=167.4 °E, A95=3.3°) agrees well with previous studies by Elming et al. [2001, 2010]. The selection of the most reliable palaeomagnetic poles for Fennoscandia and Volgo-Sarmatia of this time indicates that the present position of the Ukrainian Shield relative to Fennoscandia is not the same as for about 1.75 Ga, when Fennoscandia occupied a subequatorial position within palaeolatitudes of 5—20 °N, and Volgo-Sarmatia was located close to the equator and rotated relative to Fennoscandia counterclockwise by about 40° compared to its present position.
Rural tourism service design based on collaborative filtering algorithm after epidemic normalization
Authors: Li Xu 
Published: September 2023

Abstract
In the epidemic, normalized tertiary and rural tourism service industries are in the economic depression stage. Under the epidemic, combined with big data technology to improve the economic income and development scale of rural tourism services become the current development trend of the tourism industry. This paper first proposes a collaborative filtering recommendation algorithm based on big data technology to study the design of rural tourism services under the new epidemic normalization. Then the basic principle of the content-based recommendation algorithm is to obtain the interests of tourists based on their historical behaviors and recommend rural tourism similar to their interest preferences, and choosing the appropriate similarity function can improve the accuracy of the neighborhood-based CF method. Finally, to meet the tourists’ demand for a full range of tourism experience services and build a rural tourism service system, the psychological demand of rural tourism tourists’ consumption is analyzed based on a collaborative recommendation algorithm. The results show that among the main factors attracting tourists, 75.54% are natural scenery, 54.68% are folk culture, 51.08% are unique flavors and food, 43.17 are experiencing rural life, and 41.73% are promoting relationships with friends. This study plays an important role in accelerating rural revitalization by attracting urban tourists back to the countryside and driving the transfer of consumer groups and the rural economy to increase income; thus, rural tourism plays an important role in accelerating rural revitalization.
Application of nonlinear regression theory based on edge computing to mathematical modeling in universities
Authors: Lu Fangfang , Tao Shuang , Wan Wenting 
Published: September 2023

Abstract
Mathematical modeling is the link between mathematics and practical problems and is the medium through which mathematics is widely used in related fields. This paper introduces the definitions of mathematical models in different disciplines and for different practical problems and gives the specific steps of mathematical modeling and the key problems to be solved in each step, the most important of which is nonlinear regression theory. The parameter estimation of the error variance of the nonlinear regression model is performed by the least squares method, and for the problem of poor numerical stability and computational complexity due to the pathological matrix in solving the least squares method, the least squares method is proposed based on adding the edge computing framework. The results show that the system efficiency of the nonlinear regression model based on edge computing is 92%, and the resource utilization is between 80% and 90% on average, which is higher than the two algorithms of RPP and RPA. The nonlinear regression model based on edge computing proposed in this paper organically combines mathematical modeling, which can make mathematical modeling play a greater role in the practical application process and solve more practical problems.
The cultivation system of cross-media narrative ability of scriptwriter talent based on cluster model
Authors: Yu Xiaonan 
Published: September 2023

Abstract
The arrival of the era of big data and integrated media has changed the way of media communication and broken the original single media narrative model. The interaction and communication between traditional media and emerging media have formed a new paradigm of narrative, i.e., cross-media narrative. Based on the purpose of studying the cross-media narrative ability cultivation system of screenwriting art talents, this paper analyzes the market growth of cross-media narrative works in the era of integrated media and the audience’s perceptions of cross-media narrative works such as IP adaptations using the K-means clustering method. From 2018 to 2021, the market share of cross-media narrative works grew from 21.1% to 35.3%, while traditional single-media narrative works declined by 34.76%. Faced with the surge of transmedia narrative works, 29.5% of viewers think the stories are unattractive, too homogeneous, and lack freshness. Another 24.6% of viewers think that the plot lacks originality and only copies novels. Another 33.2% of viewers think there is plagiarism and piracy. The current cross-media narrative works still have many problems, such as rough production and a lack of polished plots. The education of film and television scriptwriting should focus on the cultivation of cross-media narrative quality, the enhancement of cross-media narrative ability, and the training of cross-media narrative skills for scriptwriting talents to cultivate high-level applied scriptwriting talents who can connect with the industry.

Vocabulary Change in Process Writing: Effect of Text Structure Instruction
Authors: Oshima Sachi 
Published: September 2023

Abstract
The purpose of this study, conducted as a follow-up study of Oshima (2020), was to examine whether Japanese EFL students’ use of vocabulary changed after being given lessons on explicit instruction on text structure and process writing. Two groups of college students—the beginner-level group writing a descriptive essay and the advanced-level group writing an argumentative essay—wrote an outline, the first draft (D1), the second draft (D2), and the final draft (FD), and I examined the differences in lexical richness between students’ D1 and FD with New Word Level Checker (Mizumoto, 2021). The results showed that both groups’ drafts had changed in the number of words used (tokens), the number of unique words used (types), and the number of lower frequency words used. This study’s finding also supports the importance of choosing an appropriate measurement to analyze students’ vocabulary levels. For Japanese students, 1K-word bands, which have been widely used in previous literature, seem too broad to capture their small vocabulary improvement.
