Authors: Lam Megan , Lu Justin Di , Elhadad Levi , Sibbald Cathryn , Alhusayen Raed
Published: February 2022

BACKGROUND

Down syndrome (DS) has been associated with cardiovascular, gastrointestinal, and immune-related abnormalities. Several dermatologic conditions, including hidradenitis suppurativa, have also been found to be associated with DS.

OBJECTIVE

The objective of this study was to characterize the prevalence, presentation, and unique features of dermatologic disorders associated with DS.

METHODS

Electronic searches of EMBASE (via Ovid), MEDLINE (via Ovid), and Web of Science databases were conducted on December 14, 2020. Observational studies including case reports of patients with DS presenting with concomitant primary dermatologic disorder were included.

RESULTS

This systematic review captured 40 observational studies and 99 case reports, including 10 observational studies that examined the prevalence of common skin disorders in patients with DS. The most common dermatologic conditions reported includes atopic dermatitis (8 studies, n=180; 19.7% mean prevalence), hidradenitis suppurativa (15, n=478; 3.2%), ichthyosis (4, n=16; 4.7%), lichen nitidus (6, n=6; 1.1%), psoriasis (21, n=65; 4.8%), alopecia areata (27, n=253; 7.4%), vitiligo (8, n=40; 4.4%), onychomycosis (3, n=198; 24.7%), calcinosis cutis (14, n=15), connective tissue nevi (6, n=6), dermatofibroma (3, n=3), melanoma (3, n=3), syringomas (14, n=182; 21.2%), and elastosis perforans serpiginosa (19, n=24; 0.5%).

CONCLUSIONS

Our results indicate an increased prevalence of common cutaneous disorders in patients with DS, particularly infectious, inflammatory, autoimmune, and connective tissue conditions. Current guidelines for the screening, general management, and use of systemic immunomodulatory agents in this patient population are lacking. Patients with DS would benefit from screening for dermatologic disorders not otherwise regularly performed for earlier diagnosis and treatment.

Virtual Dermatology and the COVID-19 Pandemic in a Resource-Limited Country Such as Nepal (Preprint)
Authors: Jha Krishna , Jha Anil Kumar
Published: February 2022

BACKGROUND

The COVID-19 pandemic has caused nationwide lockdown, which led to the disruption of health services. Despite being a rising health care modality in Nepal, virtual dermatology services became an effective tool to provide dermatologic care through web-based consultations throughout the country. Therefore, we assessed the implementation of teledermatology services at our center to provide uninterrupted health services across the country during the pandemic.

OBJECTIVE

This study aimed to evaluate the clinicodemographic profile of patients using teledermatology services and patient acceptance of this service.

METHODS

A retrospective, single-center, observational study was carried out. Clinicodemographic data from the patients using teledermatology services were obtained and analyzed. A set of questionnaires regarding patients’ acceptance of teledermatology services were administered to the patients through a survey via telephone calls, and the obtained data were interpreted.

RESULTS

A total of 122 teleconsultations were carried out within the country. The mean age of patients was 33.48 (SD 17.89) years. Of these 122 patients, 79 (64.8%) were from outside and 43 (35.2%) were from inside the city where the institute is located. The average distance from the institute to the patients’ residence was approximately 144.84 (SD 157.20) km, and the mean travel time was approximately 385.31 (SD 889.52) minutes. In total, 89 patients could be contacted, of whom 81 (91%) found the service easy to use, 75 (84.3%) were able to express their problems in a manner similar to that during direct visits, 49 (55.05 %) thought that the teleconsultation was the same as an in-person visit, 80 (89.9%) were satisfied, and 85 (95.5%) agreed to use teledermatology services in the future. Superficial fungal infection was the most common diagnosis (24.6 %). Newly registered patients were more satisfied than follow-up patients (96.36% vs 79.41%, respectively; P=.01).

CONCLUSIONS

This study highlights the importance of virtual dermatology services to deliver dermatologic care during the pandemic in Nepal. In the future, this program has a promising role in providing health care services to meet the medical needs of patients.
Interobserver and Human–Artificial Intelligence Concordance in Differentiating Between Invasive and In Situ Melanoma (Preprint)
Authors: Polesie Sam , Paoli John
Published: February 2022

BACKGROUND

Machine learning algorithms including convolutional neural networks (CNNs) have recently made significant advances in research settings. Even though several algorithms nowadays are targeted directly to the consumer market, their implementation in clinical practice is still pending. Most melanomas are easy to recognize even without the aid of dermoscopy. Nonetheless, it is often more challenging to discriminate between invasive melanoma and melanoma in situ (MIS) in a preoperative setting even with the assistance of dermoscopy. Although several dermoscopic features suggestive of MIS and invasive melanomas have been presented, their usefulness in a larger setting is limited by how well physicians agree on their presence or absence.

OBJECTIVE

The overarching aims of this research project are to identify useful dermoscopic features to help dermatologists predict melanoma thickness and to develop CNNs that can assist dermatologists in the preoperative assessment of melanoma thickness. The ultimate aim is to develop algorithms that can strengthen patient care, improve clinical decision-making, and be used in routine health care.

METHODS

We have included dermoscopic images as well as clinical close-up images of invasive melanomas and MIS from our department during the time period of January 1, 2016, to December 31, 2020. Using this image material, we have trained, validated, and tested two separated CNNs based on dermoscopic and clinical close-up images. We have also invited dermatologists to review the test sets and, for a subset of the dermoscopic images, asked them to specify the presence of prespecified dermoscopic features. Subsequently, we compared CNN outputs to the combined dermatologists’ output for all lesions and assessed the interobserver agreement for several dermoscopic features.

RESULTS

The CNN developed using dermoscopic images performed on par with the invited dermatologists whereas the CNN using clinical close-up images was outperformed by the group of dermatologists. Two dermoscopic features (atypical blue-white structures and shiny white lines) both displayed a moderate to substantial interobserver agreement and were both indicative of invasive melanomas >1.0 mm.

CONCLUSIONS

CNNs used to differentiate between invasive melanomas and MIS might be an example of a clinically relevant machine learning application, but they need further refinement and evaluation in prospective clinical trials. Only a few dermoscopic features are helpful in distinguishing melanoma thickness.
Fall Detection: a Camera and LiDAR Based Fall Detection System using Pose Estimation model (Preprint)
Authors: Wang Han Wei , Lai Feipei
Published: February 2022

BACKGROUND

Fall is dangerous for human, sometimes may cause body malfunction. Moreover, fall is dangerous especial for elder & newborn babies. According to statistics of World Health Organization, falls are the second leading cause of unintentional injury deaths worldwide. Each year an estimated 684,000 individuals die from falls globally of which over 80% are in low and middle income countries. Adults older than 60 years of age suffer the greatest number of fatal falls. 37.3 million of falls that are severe enough that require medical attention each year. It is possible to minimize the damage if we can make medical treatment as soon as possible after fall. We propose a new mechanism to detect fall using camera and LiDAR technology.

OBJECTIVE

Our goal is to make fall detection as precise as possible. We take advantage of camera and LiDAR to get the world 3D coordinate of the scene with human, and through pose estimation model to get human skeleton. Then we can do fall analysis using the 3D coordinate of human body. We can save more time for rescuers to rescue someone after fall. The scenario application of this system can be home, hospital, road, construction site, even factory, any place with human being.

METHODS

We take a photo of human using a camera and LiDAR. Then we use the 2D camera photo as the input of pose estimation machine learning model to get the 2D coordinate of human body. Then we transfer these 2D coordinates of human body into 3D coordinates by the 2D coordinates data and the depth information of LiDAR. Then we can detect if a man/woman is falling or not according to the 3D coordinate of the human body.

RESULTS

We analyze 4 poses of 5 rounds of 3 testers. The accuracy of this system is good (92.5%) even when parts of the body go out of camera sight. Both male and female and child testers with various height could be correctly detected (male of 182 cm, female of 160 cm and child of 98 cm). A fall can be detected and alerted in real time (more than 20 frames per second). Although there are some false negative when testing a fall pose. But many frames are analyzed during the single fall. Most of fall correctly alerted is enough for a rescue.

CONCLUSIONS

3D coordinate is more precise and easier to do judgement than 2D coordinate. We can get 3D coordinate by combining the 2D coordinate of camera and the depth information of LiDAR. And Apple already launched some iOS and iPadOS device with camera and LiDAR. In this paper we use iPad Pro 11” 3rd edition to do this work, which means this mechanism is of low cost and easy to implement.

A diferencia de otros espacios abiertos y verdes del campus de Ciudad Universitaria de la UNAM, la explanada central o Las Islas —vox populi—, a pesar de su protagonismo en el conjunto, ofrece grandes preguntas sobre su identidad. En este estudio se explora la formación histórica de esta gran explanada, en busca de comprenderla en su materialidad y concepción. Se demuestra cómo la vegetación fue incorporada tempranamente, con una intencionalidad de integración plástica, y se ponen en contexto los problemas para su adecuada interpretación. La discusión se aterriza en una serie de recomendaciones para la conservación de la explanada y sus atributos, como parte del conjunto universitario, declarado Patrimonio de la Humanidad por la UNESCO en 2007.
De la macro a la microhabitabilidad del espacio doméstico interior en tiempos de pandemia. Introducción al caso de estudio en Aguascalientes capital
Authors: Esparza Díaz de León Mario Ernesto
Published: February 2022

Habitar representa un concepto complejo no solo de describir sino de interpretar y configurar, tanto para el arquitecto o diseñador como para todo ser humano. Las diversas situaciones cotidianas presentan condiciones y variables que, en mayor o menor medida, inciden en la definición conceptual y material del habitar, y en el significado del ámbito como escenario mental o arquitectónico para la construcción de un discurso de vida que a diario establece diálogos y relaciones de experiencia entre el mismo habitante y sus diferentes contextos urbanos, culturales y sociales en distintas escalas. La situación de pandemia experimentada desde inicios de 2020 por la COVID-19 ha representado, en diferentes áreas y niveles, situaciones complejas traducidas en proyectos y manifiestas en espacios habitables. ¿Cómo ha sido la experiencia del espacio doméstico en pandemia y qué repercusiones tangibles e intangibles ha tenido, particularmente en la ciudad de Aguascalientes, México?
Familia y comunidad determinantes de la vida cotidiana en el diseño participativo de la vivienda
Authors: Vázquez Cruz Irving
Published: February 2022

Presentar el diseño participativo requiere profundizar en los procesos sociales, es decir posicionar a la narrativa que expresa las necesidades sentidas y reales de quienes habitan viviendas como espacios que refugian dinámicas cotidianas distintas, que generan rupturas epistemológicas en el imaginario y representación tácita de la reproducción social de la vivienda. Las necesidades de habitabilidad se deben adecuar a las inquietudes de la vida cotidiana, más aún en contextos de desigualdad social urbana. Es por ello que se presenta una aproximación al estudio de la importancia de la cotidianidad en el diseño participativo de la vivienda, el cual, a través de una metodología cualitativa, rescata la narrativa cotidiana en las expresiones que hay en la dinámica familiar, en el uso y habitabilidad rutinaria de la vivienda y las relaciones sistémicas con el espacio público que integran a la comunidad.

Implementation of Particle Swarm Optimization (PSO) to Improve Neural Network Performance in Univariate Time Series Prediction
Authors: Tyas Fitri Ayuning , Setianama Mamur , Fadilatul Fajriyah Rizqi , Ilham Ahmad
Published: February 2022

One of the oldest known predictive analytics techniques is time series prediction. The target in time series prediction is use historical data about a specific quantity to predicts value of the same quantity in the future. Multivariate time series (MTS) data has been widely used in time series prediction research because it is considered better than univariate time series (UTS) data. However, in reality MTS data sets contain various types of information which makes it difficult to extract information to predict the situation. Therefore, UTS data still has a chance to be developed because it is actually simpler than MTS data. UTS prediction treats forecasts as a single variable problem, whereas MTS may employ a large number of time-concurred series to make predictions. Neural Network (NN) model could be built to predict the target variable given the other (predictor) variables. In this study, we used Particle Swarm Optimization (PSO) algorithm to optimize performance of NN on a UTS dataset. Our proposed model is validated using x-validation and and use RMSE to measure its performance. The experimental results show that NN performance after optimization using PSO produces good results compared to classical NN performance. This is evidenced by the value of RMSE = 0.410 which is the smallest RMSE value produced. The smaller the RMSE value, the better the model performance. It can be concluded that the proposed method can improve NN performance on UTS data.

Published: February 2022

Classification of skin cancer is an important task to detect skin cancer and help with the treatment of skin cancer according to its type. There are many techniques in imaging used to classify skin cancer, one of the superior deep learning (DL) algorithms for classification is the Convolutional Neural Network (CNN). One type of skin cancer is dangerous is melanoma. In this study, CNN is proposed to help classify this type of skin cancer. The dataset consists of 15103 images of skin cancer pigments with 7 different types of skin cancer. These three tests proved malignant skin lesions can be classified with higher accuracy than non-melanocytic skin lesions which is 90% and performance evaluation shows melanocytic and non-melanocytic skin lesions detected with the highest accuracy. The tests conducted in this study grouped several types of skin diseases namely the first tests conducted using a group of melanocytic and non-melanocytic skin disease, second testing using groups of melanoma and melanocytic nevus diseases, and the final testing using malignant and benign. The proposed CNN model achieved significant performance with a best accuracy of 94% on the classification of melanoma and melanocytic nevus.

Published: February 2022

O objetivo deste estudo foi identificar, por um levantamento etnobotânico, o comportamento de compra e frequência de uso de cosméticos, bem como as plantas utilizadas para esses fins. Essa pesquisa foi realizada por meio de questionários on-line destinado exclusivamente às mulheres. O questionário foi respondido por 59 mulheres com idade entre 18 e 30 anos. A maioria (77,2%) afirma que a internet, amigos e familiares são as principais influências para a escolha dos produtos que utilizam, sendo os produtos para o cabelo, higiene corporal e íntima os mais usados. As plantas acerola, uva, abacaxi, morango e caju foram as frutas reconhecidas com ação anti-idade contribuindo com a pele. A partir dessa pesquisa, foi possível observar que as mulheres carregam conhecimento cultural sobre plantas, entretanto muitos desses conhecimentos são a partir de redes sociais. Nessa perspectiva, esse saber não garante eficiência, tornando necessário o desenvolvimento de estudos que confirmem essa percepção popular. Infere-se a necessidade de estudos a fim de proporcionar segurança na sua utilização tanto para os consumidores como para o meio ambiente, seja na sua forma in natura ou em associação com cosméticos, associado com a preservação da biodiversidade de forma sustentável pode contribuir nas relações de saúde única.

In total arch replacement, using frozen elephant trunk (FET) or elephant
trunk techniques ensures proximalization of the distal anastomosis.
However, in some cases, the left subclavian artery (LSCA) is deeply
located and difficult to visualize. Therefore, surgeons face technical
challenges during the LSCA reconstruction. We report an end-to-side
anastomosis technique that enables safer and easier anatomical
reconstruction of the LSCA.

Improving the efficacy of extended storage for reducing the risk of viral contaminated plant-based feed ingredients through investigating ambient temperature requirements.
Authors: Dee Nicholas , Havas Karyn A. , Shah Apoorva , Singrey Aaron , Spronk Gordon , Niederwerder Megan , Nelson Eric , Dee Scott
Published: February 2022

Viruses of veterinary significance such as African swine fever virus,
are known to survive for extended periods in plant-based feed
ingredients imported into North America. To reduce the likelihood of
virus introduction, high-risk ingredients, such as oil seed meals, are
stored in designated facilities for extended periods under controlled
environmental conditions to minimize viral infectivity prior to use in
diets. While 30 days has become a standard storage period, the required
ambient temperature to inactivate viruses during this time is not known.
To address the question, 1-metric ton totes of conventional soybean meal
were inoculated with PRRSV 144 lineage 1C variant and SVA prior to
storage for 30 days at 23.9º C, 15.5º C, or 10º C, and feeding to pigs.
Virus infectivity was evaluated through detection of viral RNA in oral
fluid samples, along with clinical signs. Results indicated that
inactivation of both viruses occurred in soy stored at 23.9º C. In
contrast, SVA infectivity was observed in soy stored at both 15.5º C and
10º C, while PRRSV 144 L1C variant infectivity was only observed in soy
stored at 10º C. These results suggest that a storage period of 30-days
and a temperature of 23.9º C are required to reduce the risk of virus
contaminated plant-based feed ingredients, such as soybean meal.

Published: February 2022

Every year, efforts are applied worldwide, particularly in the European Union, to improve health care systems by increasing the added value of resources already available for health care financing by increasing the performance of health care systems. According to experts of the World Health Organisation (WHO) and the Organisation for Economic Cooperation and Development (OECD), 20–40% of the resources are used for complications that could be avoided, for unnecessary treatment or administrative inefficiency. Therefore, a new initiative to improve health performance – the value-based health care concept (VBHC) is becoming increasingly popular in the world, and particularly in Europe. This scientific article aims to explore the possibilities of applying VBHC in Latvia and the interaction between various management tools in the field of health care. Application of the VBHC concept in Latvia is offered for discussion, where the outcome of the corresponding measure would be identified for each health service provider as part of a one-patient (care) pathway involving several independent health service providers. Based on the Health Care System Performance Assessment (HSPA), clinical (patient) pathways and indicators, to initiate an integrated VBHC model in four priority areas: circulatory system diseases, oncology, mental health, maternal and child health. Meta-analysis of the research is based on the use of qualitative data sources – the existing data sources from policies implemented by the Ministry of Health in Latvia and examples of the introduction of VBHC initiatives worldwide summarised by the VBHC Center Europe. The deductive research is based on the Value-Based Healthcare concept introduced by Porter and Teisberg (2007)
The Impact of the COVID-19 pandemic on the unemployment rate in Latvia
Authors:   Latvia University of Life Sciences and Technologies, Hohlova Vera , Rivza Baiba ,   Latvia University of Life Sciences and Technologies
Published: February 2022

The economic and labour market consequences of Covid-19 were immediate, significant and lasting, with longterm negative effects on global economic development and activity in general. The global virus pandemic is having a profound effect on the labour market with a sharp rise in the number of unemployed, which are at high risk of becoming long-term unemployed as the pandemic drags on, some of whom will not return to the labour market. The outbreak of Covid-19 and the measures taken to combat it are leading to a rapid demand for unemployment benefits, but a large proportion of the unemployed registered with employment agencies are not actively involved in job search or do not want to establish an employment relationship at all. It is important to track and describe the major changes in the labour market around the world, but the restrictions that are being put in place to combat Covid-19 pose a huge obstacle to conventional data collection approaches and activities. Within the framework of this study, the unemployed in Latvia were interviewed in order to find out and evaluate the impact of the Covid-19 pandemic on the unemployment rate and the unemployed in Latvia. The aim of the article is to find out problems caused by the Covid-19 pandemic, which are related to the unemployed and which need to be solved in Latvia, and possibly also in other European and other countries of the world.

COVID-19 policy and measures have caused both negative and positive challenges for the transport sector. The aim of the research is to model an impact of shocks that transport and logistics encounter during the COVID-19 era on the economy and regional development. A comparative-static approach that involves an input-output model with additional regional modelling block and scenarios are applied. Two scenarios are estimated for Latvia’s economy: firstly, extremely dramatic decline in demand on air transport services by 90%; secondly, unexpected increase in demand for postal and courier services that doubled output. The results of the first scenario argue that the service sector is influenced more than manufacturing due to air transport collapse –rental and leasing services (-11.6%), employment services (-9.7%), other transport services (-7.0%), impact on manufacturing is relatively minor and only on certain branches. The results of the second scenario on doubled output in postal and courier services argue that there is a positive impact, but the scale is relatively low, the most affected industries are manufacturing (of paper products (increase by 1.7%), rubber and plastic goods (1.6%)). The findings confirm that the urban areas due to higher economic activity and larger service sector are more affected to the modelled shocks both negative and positive. The rural areas are relatively less negatively affected during the crisis, but at the same time, during the recovery (for example, in the post-COVID era) it may lead to weaker economic activity and the rural areas will continue to lag behind urban areas.

This research paper summarises the results of the rapid changes in the structure of the economic system as a result of the impact of the Covid-19 pandemic in 2020. The following tasks were set for the research: to describe the national economic system before COVID-19 pandemic in Latvia, to identify and assess the main features of changes in the national economic system during 2020 and to identify and assess the geographical location of structural changes in the country. The obtained results indicate three main tendencies in the structure of the economic system. Some economic segments indicate that the number of employees has increased in the time of the pandemic influence, some almost remained unchanged or experienced a decrease. As the linear changes in the volume of employees in the elements of the main structure of the economy take place to a different extent, then there is also an increase or decrease in the share of certain main segments in the regions of Latvia.

Aunque la producción y el consumo de prendas de vestir generan altos impactos negativos en términos ambientales y sociales, pocos estudios han explorado el consumo socialmente responsable de vestuario de los colombianos. Este estudio, con enfoque etnográfico, tiene el propósito de conocer los criterios de decisión asociados al consumo responsable de vestuario en adultos entre los 30 y 44 años de nivel socioeconómico medio-alto de la ciudad de Medellín, en Colombia, a partir de 14 entrevistas semiestructuradas y seis ejercicios de observación participante. Se encontró un bajo nivel de conciencia sobre el impacto social y ambiental de estos consumos y que las prácticas de consumo responsable están limitadas por la información y la disponibilidad de alternativas sostenibles en el mercado. Los resultados revelan cuatro perfiles de consumidores según el consumo socialmente responsable de vestuario, que ofrece implicaciones tanto para la literatura de mercadeo de la moda como para las marcas de moda que están o quieren incursionar en la sostenibilidad.
Kynni unglinga af vinsælum ferðamannastöðum: Frístundir, ferðalög og menntun

Ferðamennska og tómstundir hafa fengið æ meira vægi í daglegu lífi fólks síðustu áratugi í kjölfar vaxandi velmegunar og breytinga á vinnumarkaði. Aðgengi að ferðamennsku og margs konar tómstundum er ólíkt og fer meðal annars eftir efnahagslegri stöðu fólks. Hérlendis er lítið vitað um samspil félagslegrar stöðu, ferðamennsku og tómstundaiðkunar. Markmið þessarar greinar er að varpa ljósi á þátttöku unglinga í ferðamennsku m.t.t. félagslegra og efnahagslegra þátta og ræða í samhengi við ferðahegðun Íslendinga innanlands, félagslega ferðamennsku og menntun. Notuð eru gögn úr HBSC-rannsókninni Heilsa og lífskjör skólabarna frá árinu 2017–2018 þar sem 6717 börn og unglingar svöruðu spurningum varðandi útiveru. Hér er gerð grein fyrir niðurstöðum spurninga um heimsóknir 12–15 ára barna og unglinga á þekkta áfangastaði á Íslandi. Niðurstöður benda til þess að eftir því sem börn eldast hafi þau komið á fleiri áfangastaði. Algengast er að svarendur segist hafa komið að Gullfossi, Geysi, á Þingvelli, í Heiðmörk og til Mývatns. Efnahagsleg staða, uppruni foreldra og búseta tengist heimsóknum á suma áfangastaði en þau áhrif eru ekki einhlít. Niðurstöður vekja upp spurningar um ólíka stöðu unglinga til að njóta ferðamennsku og tómstunda, um grundvöll fyrir frekari uppbyggingu félagslegrar ferðamennsku hérlendis og tengsl hennar við menntun og hlutverk skólakerfisins í því sambandi. Reifuð eru álitamál þessu tengd og vörðuð verðug rannsóknarefni á þessu sviði.
¡No quiero estudiar otra ciencia que invisibilice a la pedagogía!

Published: February 2022

Conocer los ámbitos de la pedagogía no es fácil en esta sociedad donde vivimos debido a la falta de conocimiento -y reconocimiento-acerca de la profesión del pedagogo. A todo ello, podemos unirle la cantidad de intrusismo laboral que existe en muchos lugares. Es por ello que expongo una breve experiencia personal para poder visibilizar la situación en la que nos encontramos la mayoría de pedagogos/as.
