Use of Social Media for Patient Education in Dermatology: Narrative Review
Authors: Wojtara Magda Sara 
Published: April 2023

Background
Social media has rapidly become one of the main avenues for news and communication among those with access to technology. Nearly 60% or 4.7 billion people worldwide use social media. Different social media networks provide users with a barrage of posts, opinions, and transformations. With this noticeable uptick in physician and patient education usage of social media, exploration of the impacts of social media on patient education in dermatology is crucial.

Objective
The goal of this narrative review was to evaluate existing peer-reviewed literature examining the use of social media for patient education in dermatology and to establish trends and implications. Additional attention was given to different social media sites, and potential differences in modalities of posts such as short-form videos on TikTok and Instagram Reels, long-form videos on YouTube, and infographics on Twitter, Instagram, and Facebook.

Methods
PubMed, Access DermatologyDxRx, and Scopus searches of peer-reviewed publications were performed to discover articles with social media and patient education keywords in combination with other health care–relevant or dermatology-relevant keywords. Subsequently, the screening of these studies was performed by the author who has experience with education and research experience in health care, dermatology, social media, and telehealth. Ultimately, the selected articles were summarized through qualitative analysis of key points and presented for further discussion.

Results
Through this narrative review, the researcher was able to identify several publications focusing on dermatology and social media. Some common subject areas included the use of social media for the promotion of private dermatology practices, residency programs, and research journals. So long as providers, such as dermatologists, take ethical considerations into account, these platforms can provide patients with curated educational content. In addition, several publications emphasized the use of social media as a form of patient education on dermatologic conditions but also as a source of misinformation.

Conclusions
This narrative review illuminated the use of social media as a form of patient education for dermatology, with its applications addressed across many demographics and situations. As social media platforms continue to update their algorithms, content filters, and posts, social media may become a reputable form of patient education in dermatology. Future studies and innovations should continue to explore innovations in this space, the efficacy of different modalities of posts, and longitudinal differences in patient outcomes and health literacy.
Obstacles to Evidence-Based Procurement, Implementation, and Evaluation of Health and Welfare Technologies in Swedish Municipalities: Mixed Methods Study
Authors: Norgren Therese , Richardson Matt X , Wamala-Andersson Sarah 
Published: April 2023

Background
Health and welfare technologies (HWTs) are interventions that aim at maintaining or promoting health, well-being, quality of life, and increasing efficiency in the service delivery system of welfare, social, and health care services, while improving the working conditions of the staff. Health and social care must be evidence-based according to national policy, but there are indications that evidence for HWT effectiveness is lacking in related Swedish municipal work processes.

Objective
This study aimed to investigate whether the evidence is used when Swedish municipalities procure, implement, and evaluate HWT, and if so, the kinds of evidence and the manner of their use. The study also aimed to identify if municipalities currently receive adequate support in using evidence for HWT, and if not, what support is desired.

Methods
An explanatory sequential mixed methods design was used with quantitative surveys and subsequent semistructured interviews with officials in 5 nationally designated “model” municipalities regarding HWT implementation and use.

Results
In the past 12 months, 4 of 5 municipalities had required some form of evidence during procurement processes, but the frequency of this varied and often consisted of references from other municipalities instead of other objective sources. Formulating requirements or requests for evidence during procurement was viewed as difficult, and gathered evidence was often only assessed by procurement administration personnel. In total, 2 of 5 municipalities used an established process for the implementation of HWT, and 3 of 5 had a plan for structured follow-up, but the use and dissemination of evidence within these were varying and often weakly integrated. Standardized processes for follow-up and evaluation across municipalities did not exist, and those processes used by individual municipalities were described as inadequate and difficult to follow. Most municipalities desired support for using evidence when procuring, establishing evaluation frameworks for, and following up effectiveness of HWT, while all municipalities suggested tools or methods for this kind of support.

Conclusions
Structured use of evidence in procurement, implementation, and evaluation of HWT is inconsistent among municipalities, and internal and external dissemination of evidence for effectiveness is rare. This may establish a legacy of ineffective HWT in municipal settings. The results suggest that existing national agency guidance is not sufficient to meet current needs. New, more effective types of support to increase the use of evidence in critical phases of municipal procurement and implementation of HWT are recommended.
Stimulant Use Associated With Psychosocial Factors, HIV Risk, and Concurrent Hazardous Alcohol Use Among US Adults: Exploratory Cross-Sectional Questionnaire Study
Authors: Lee Frank , Jain Jennifer Payaal , Duthely Lunthita M , Ikeda Janet , Santos Glenn-Milo 
Published: April 2023

Background
Stimulant use is a major public health problem that contributes to morbidity and mortality among men who have sex with men (MSM) in the United States. To reduce the harms associated with stimulant use, there is a need to identify the factors associated with stimulant use to inform interventions. Additionally, there is a need to use large crowdsourcing platforms like Amazon Mechanical Turk (MTurk) to engage more individuals who use substances across the United States.

Objective
We identified the correlates of stimulant use among people who use alcohol or stimulants in the United States recruited using MTurk.

Methods
Participants who were aged ≥18 years in the United States and reported alcohol or stimulant (ie, cocaine, crack cocaine, and methamphetamine) use were deemed eligible and recruited via the web platform MTurk. Participants completed a baseline survey, which assessed sociodemographics, psychosocial (ie, depression, affect, self-esteem, and stress) factors, substance use, and sexual behaviors. Data were collected and analyzed with STATA (version 17; StataCorp). Stratifying by MSM status, bivariate and multivariable logistic regression models were built in STATA to examine the correlates of stimulant use. Multivariable models controlled for age, race, health insurance, and relationship status.

Results
Of 272 participants, 201 (73.9%) identified as male, 134 (49.2%) were MSM, 52 (19.1%) were from racial and ethnic minoritized communities, and 158 (58%) were in a relationship. The mean age was 36.10 (SD 10.3) years. A total of 40 (14.7%) participants reported stimulant use in the past 6 months. Factors significantly associated with stimulant use were being MSM (adjusted odds ratio [aOR] 4.61, 95% CI 1.97-10.81), a higher Alcohol Use Disorders Identification Test-Concise score (aOR 1.24, 95% CI 1.08-1.42), more intense cravings for alcohol in the past 24 hours (aOR 1.03, 95% CI 1.01-1.04), a higher depression score (aOR 1.06, 95% CI 1.01-1.12), a greater number of male partners in the last 6 months (aOR 1.32, 95% CI 1.08-1.61), a greater number of female partners in the last 6 months (aOR 1.42, 95% CI 1.04-1.92), and being diagnosed with a sexually transmitted infection (eg, syphilis, gonorrhea, chlamydia, herpes simplex virus, human papillomavirus, and other) in the last 6 months (aOR 14.61, 95% CI 3.45-61.87). Additionally, there was a significant additive interaction between MSM status and negative affect, such that the impact of negative affect on stimulant use was significantly greater among MSM compared with non-MSM (relative excess risk due to interaction 0.085, 95% CI 0.037-0.13).

Conclusions
Interventions that address stimulant use should use evidence-based approaches that reduce negative affect, depression, and cravings for alcohol. Additionally, interventions should be customized for MSM populations.
Use of Peer-Led Web-Based Platforms for Peer-Assisted Learning Among Canadian Anesthesia Residents and Fellows: Cross-Sectional Study (Preprint)
Authors: Li Casey , Salman Maria , Esmail Tariq , Matava Clyde 
Published: April 2023

BACKGROUND

Peer-assisted learning (PAL) using peer-led web-based platforms (PWPs), including social media, can be a highly effective method of supporting medical trainees. PWPs, such as mobile apps for sharing anesthesia resources and social media groups or discussion forums pertaining to anesthesia training, may play a role in facilitating anesthesia trainee-led web-based education. However, there have been many challenges facing anesthesia trainees when it comes to incorporating PWPs, especially social media and mobile apps for PAL.

OBJECTIVE

The primary objective of this survey was to assess the proportion of trainees that use social media and mobile apps. The secondary objective was to identify the trainees’ perceptions on the use of social media and mobile apps for educational purposes, including PAL.

METHODS

This cross-sectional study was conducted through a survey administered via email at a single large academic center. The survey tool collected data between 2016 and 2017 on the following: demographic data (year of study, field of specialty), use of technology and web-based resources for medicine, use of social media platforms for anesthesia or training, benefits and barriers to future uses of social media for training, and ideas for trainee-led websites. Descriptive statistics were reported.

RESULTS

In total, 80 anesthesia trainees (51 residents and 29 fellows) responded to the survey (response rate of 33% of out 240 trainees contacted). All trainees reported having a mobile device that most (n=61, 76%) reported using multiple times a day to access medical resources. The highest perceived benefits of PWPs according to residents were that the most valuable information was available on-demand (n=27, 53%), they saved time (n=27, 53%), and they improved their overall learning experience within anesthesia (n=24, 47%). In comparison, fellows thought that PWPs were beneficial because they provided multiple perspectives of a single topic (n=13, 45%) and served as an additional platform to discuss ideas with peers (n=13, 45%). The most popular platforms used by both residents and fellows were Facebook (residents: n=44, 86%; fellows: n=26, 90%) followed by LinkedIn (residents: n=21, 42%; fellows: n=9, 29%). Even though most anesthesia trainees used social media for personal reasons, only 26% (n=21) reported having used resident- or fellow-driven PWP resources. Examples of PWPs that trainees used included anesthesia groups and a resident Dropbox resource folder.

CONCLUSIONS

There was generally an acceptance for using PWPs for PAL as they provided various benefits for trainees at all levels of learning. PWPs have the potential to garner an increased sense of community and sharing within learning experiences throughout all levels of training. The information gained from this survey will help inform the basis for developing an anesthesia trainee-led e-learning platform.

Análisis exploratorio de los coeficientes de Rasmussen para la economía chilena, mediante las tablas input-ouput, período 1996 - 2008
Authors: Pino Arriagada Osvaldo , King Domínguez Andrea 
Published: April 2023

El objetivo de este trabajo es analizar la naturaleza de las actividades gravitantes de la economía chilena, por medio de un análisis comparativo y exploratorio de los coeficientes de Rasmussen. El estudio considera para el análisis las tablas input-ouput (12 x 12 sectores) del Banco Central de Chile de los años 1996, 2003 y 2008, su matriz inversa, los Multiplicadores de la producción y Multiplicadores de la expansión uniforme de la demanda. Luego se construyen los índices de poder de dispersión y sensibilidad de dispersión para cuantificar la naturaleza de los eslabonamientos sectoriales. Finalmente, se caracteriza cada actividad económica como clave, estratégica, impulsora o isla. Los resultados apoyan la hipótesis de permanencia estructural: las variables cambian, pero las relaciones entre ellas se mantienen constantes. AbstractThe purpose of this study is to analyze the nature of the important activities, in the Chilean economy, using Rasmussen´s coefficients by means of an exploratory and comparative analysis. This study incorporate the Chilean Central Bank´s input – output tables (12 x 12 sectors) for the years 1996, 2003 and 2008. Incorporating the estimation of the inverse matrix, the production multipliers and the uniform demand expansion multiplier, the authors constructed indices of dispersion power and dispersion sensibility for the quantification of productive linkages. Finally, based on these indices, every activity is characterized as key, strategic, driver and island sectors, for 1996, 2003 and 2008. The results support the hypothesis of structural permanence. The variables changes, but the relationship between them remains constant.

Authors: Laser Procianoy Jairo , Frota Decourt Roberto 
Published: April 2023

El propósito de este trabajo es evaluar, si en un sistema legal débil, existe algún mecanismo legar para aumentar la vigilancia accionistas sobre la gestión y obtener mejores resultados para ellos. Se utilizó la prueba T para verificar si la media de cada variable analizada presentó diferencias significativas entre empresas con y sin Consejo Fiscal. Encontramos que la existencia de un Consejo Fiscal activo se asocia con un mayor ROE. También se encontró que las empresas con el Consejo Fiscal se involucran mucho menos en earnings management. El Consejo Fiscal es un importante mecanismo de protección de los accionistas y el control permitido por la ley. Es una persona jurídica separada independiente del consejo de administración y de gestión. AbstractThe purpose of this paper is to test, even in a weak legal system, there is any legal mechanism to increase shareholders monitoring over the management and get better results for them. We used the T test to verify if the mean of each analyzed variable has presented significant difference between firms with and without Fiscal Council. We found that the existence of an active Fiscal Council is associated with higher ROE which it improves firm performance. We also found that firms with Fiscal Council engage significantly less in earnings management. The Fiscal Council is an important mechanism of shareholders protection and monitoring allowed by the Law. It a separate corporate body independent of the board of directors and management.
Análisis económico de una casa eficiente con uso de energía fotovoltaica
Authors: Zúñiga Jara Sergio , Álvarez Madeleyn , Santander Meybol , Serrano Edxell 
Published: April 2023

El estudio aplica una metodología para evaluar la conveniencia económica de una inversión en energía fotovoltaica para una familia típica. Se permite concluir, en base al Valor Actual Neto (VAN) y la Tasa Interna de Retorno (TIR) que el éxito de este tipo de proyectos de escala familiar está fuertemente condicionado por el monto de la inversión inicial y reinversiones. Como resultado final, los proyectos no resultaron rentables aún después de un análisis de sensibilidad de variables críticas, que incluyó la existencia de subsidios. Esto parece explicar el por qué cuando se adquieren estos equipos a través de un subsidio del Estado, es frecuente ver que los usuarios no realizan las reinversiones necesarias y terminan abandonándolos. AbstractThis study evaluate the economic attractiveness of an investment in photovoltaicenergy for a typical family. Based on the Net Present Value and the Internal Rate of Return we established that the success of this type of family-scale projects is strongly affected by the amount of the initial investment and the reinvestment. As a final result, the projects were not profitable even after a sensitivity analysis of critical variables, which included the existence of subsidies from the Government. This seems to explain why when purchasing this equipment through a subsidy, it is common to see that users do not perform the necessary reinvestments and end up abandoning them.

Published: April 2023

La presente investigación pretende identificar los factores determinantes del desarrollo económico, realizando un análisis cuantitativo comparativo entre Chile y otros países o regiones. Para medir el comportamiento del desarrollo económico, se utiliza como variable endógena el Producto Interno Bruto. Las variables exógenas que lo explicarían se someten a un análisis factorial, para posteriormente seleccionar a través de un modelo econométrico aquéllas que sean las más relevantes. Finalmente se realiza una comparación relativa del PIB de Chile en relación a los demás grupos para establecer potenciales relaciones entre sus series, lo que se hace por medio de un análisis de cointegración de los residuos de la serie del PIB para la frontera de tiempo del estudio. AbstractThis research is oriented to identify and analyzed the contributing factors to economic development through a quantitative comparative study between Chile and other countries and regional areas. Thus, the behavior of economic development is measure by the Gross Domestic Product as endogenous variable. The exogenous variables that explain subjected to factor analysis, and subsequently selected through an econometric model of those which are the most relevant. Finally, a cointegration analysis is run to establish eventual correlation among the GDP of the countries consider in the present study.

Published: April 2023

La internacionalización de la empresa es un tema relevante en el estudio de las organizaciones. Es por ello, que el presente estudio comparativo persigue dos objetivos: En primer lugar, realizar una revisión teórica sobre las estrategias de entrada a mercados externos, y en segundo lugar, contrastar los planteamientos anteriores para aportar evidencia empírica al respecto, a partir de una muestra de empresas chilenas y españolas. El contraste se realizará sobre las empresas internacionalizadas y cuyo país de origen sea Chile o España. Las fuentes de información utilizadas serán la base de datos de las Sociedades Anónimas reguladas por la Superintendencia de Valores y Seguros (SVS) en el caso chileno y la Comisión Nacional del Mercado de Valores (CNMV) en el caso español, para el periodo 2007-2008. Los resultados del análisis descriptivo permiten observar que la principal forma de entrada a mercados externos es la exportación, indiferente del país analizado. En conclusión, las empresas optan por esta modalidad por el menor riesgo e inversión que implica esta estrategia. AbstractThe internationalization of the firm is an important topic in the study of the organizations. It is because of this that the present comparative study pursues two goals. Firstly, to realize a bibliographic revision on the entrance strategies to external markets, and secondly, to contrast the previous ideas to give an empirical evidence., starting from a sample of Chilean and Spanish firms. The contrast will be carried out on the internationalized firms and whose origin country is Chile and Spain. The sources of information will be the database of the Anonymous Societies regulated by the Superintendent of Securities and Insurance (SVS) in the Chilean case and the National Commission of the Stock Market (CNMV) in the Spanish case, for the period 2007-2008. The results of the descriptive analysis allow to observe that the main entrance form to external markets is the export, indifferent of the analyzed country. In conclusion, the firms opt for this modality for the smallest risk and investment that this strategy imply.
