Evaluación de signos vitales mediante una aplicación móvil en pacientes con insuficiencia cardiaca: ¿una oportunidad para la titulación remota? / Evaluation of vital signs through a mobile application in patients with heart failure: a opportunity for remote titration?

Resumen Antecedentes: Las consultas virtuales aumentaron exponencialmente, pero presentan como limitación la imposibilidad de valorar los signos vitales (SV), siendo especialmente útiles en los pacientes con insuficiencia cardiaca (IC) para titular medicación que modifica pronóstico. Este problema podría potencialmente solucionarse mediante una herramienta que pueda medir la presión arterial (PA) y frecuencia cardiaca (FC) de manera precisa, accesible y remota. Los teléfonos móviles equipados con tecnología de imágenes ópticas transdérmicas podrían cumplir con estos requisitos. Objetivo: Evaluar la precisión de una app basada en imagen óptica transdérmica para estimar SV en relación con la valoración clínica en pacientes con IC. Métodos: Estudio de cohorte prospectivo, se incluyeron pacientes evaluados en una unidad ambulatoria de IC de febrero a abril del 2022. Se valoró simultáneamente la PA y FC mediante la app y el examen clínico (PA con un esfigmomanómetro automatizado y FC por palpación braquial). Se realizaron tres mediciones por app y clínica en cada paciente, por dos médicos independientes, encontrándose ciegos a los resultados. Resultados: Se incluyeron 30 pacientes, con 540 mediciones de TA y de FC. Edad media de 66 (± 13) años, el 53.3% de sexo masculino. La fracción de eyección del ventrículo izquierdo media fue de 37 ± 15, con hospitalizaciones previas por IC el 63.3%, en CF II-III el 63.4%. La diferencia media entre la medición de la app y su medición de referencia clínica fue de 3.6 ± 0.5 mmHg para PA sistólica (PAS), 0.9 ± -0.2 mmHg para PA diastólica (PAD) y 0.2 ± 0.4 lpm para FC. Cuando se promedian las diferencias medias emparejadas para cada paciente, la media entre los 30 pacientes es de 2 ± 6 mmHg para PAS, -0.14 ± 4.6 mmHg para PAD y 0.23 ± 4 lpm para FC. Conclusión: La estimación de PA y FC por una app con tecnología de imagen óptica transdérmica fue comparable a la medición no invasiva en pacientes con IC, y cumple los criterios de precisión de la medición de PA en este estudio preliminar. La utilización de esta nueva tecnología de imagen óptica transdérmica brinda datos prometedores, que deberán ser corroborados en cohortes de mayor tamaño.

Abstract Background: Virtual consultations have increased exponentially, but a limitation is the inability to assess vital signs (VS). This is particularly useful in patients with heart failure (HF) for titrating prognosis-modifying medication. This issue could potentially be addressed by a tool capable of measuring blood pressure (BP) and heart rate (HR) accurately, remotely, and conveniently. Mobile phones equipped with transdermal optical imaging technology could meet these requirements. Objective: To evaluate the accuracy of a transdermal optical imaging-based app for estimating VS compared to clinical assessment in patients with HF. Methods: A prospective cohort study included patients evaluated in an HF outpatient unit between February and April 2022. BP and HR were simultaneously assessed using the app and clinical examination (BP with an automated sphygmomanometer and HR by brachial palpation). Three measurements were taken by both the app and clinic for each patient, by two independent blinded physicians. Results: Thirty patients were included, with 540 measurements of BP and HR. The mean age was 66 (± 13) years, 53.3% were male. The mean left ventricular ejection fraction was 37 ± 15, with 63.3% having previous hospitalizations for HF, and 63.4% in NYHA class II-III. The mean difference between the app measurement and its clinical reference measurement was 3.6 ± 0.5 mmHg for systolic BP (SBP), 0.9 ± -0.2 mmHg for diastolic BP (DBP), and 0.2 ± 0.4 bpm for HR. When averaging the paired mean differences for each patient, the mean across the 30 patients was 2 ± 6 mmHg for SBP, -0.14 ± 4.6 mmHg for DBP, and 0.23 ± 4 bpm for HR. Conclusion: The estimation of BP and HR by an app with transdermal optical imaging technology was comparable to non-invasive measurement in patients with HF and met the precision criteria for BP measurement in this preliminary study. The use of this new transdermal optical imaging technology provides promising data, which should be corroborated in larger cohorts.

Nomofobia e pandemia: um estudo sobre o medo de ficar desconectado no Brasil / Nomophobia and the pandemic: a study on the fear of being disconnected in Brazil / Nomofobia y pandemia: un estudio sobre el miedo a la desconexión en Brasil

As Tecnologias da Informação e Comunicação estão presentes na vida humana. Oferecem diversas vantagens, mas podem provocar problemas, entre eles a nomofobia ­ a angústia e o medo de se tornar incomunicável, sem acesso ao smartphone ou à internet. Para avaliar o grau de nomofobia foi criado o Nomophobia Questionnaire (NMP-Q). O objetivo deste artigo foi avaliar em que medida o isolamento social, como medida preventiva à covid-19, interferiu nos índices de nomofobia no Brasil. Foi aplicada uma versão adaptada do instrumento NMP-Q, durante a pandemia, a jovens através das mídias digitais. Os resultados indicam que o isolamento social interferiu no aumento da nomofobia, sobretudo em mulheres de 20 a 29 anos e de 50 a 59 anos, universitárias ou com pós-graduação e ganhando de 10 a 20 salários-mínimos. Este artigo se inscreve no conjunto de estudos internacionais que usaram o NMP-Q para avaliar o medo de ficar desconectado.

The Information and Communication Technologies are present in human life. They offer many advantages, but they can also cause problems, among them nomophobia ­ anguish and fear of becoming incommunicado, without access to a smartphone or internet. To assess the degree of nomophobia, the Nomophobia Questionnaire (NMP-Q) was created. The objective of this article was to evaluate to what extent the social isolation proposed as a preventive measure against covid-19 interfered in the indices of nomophobia in Brazil. An adapted version of NMP-Q was applied to young people through digital media during the pandemic. The results indicate social isolation interfered with the increase of nomophobia, especially in women aged 20 to 29 and 50 to 59 years, with university degree or post-graduation and earning 10 to 20 minimum wages. This article is part of a set of international studies that used the NMP-Q to assess the fear of being disconnected.

Relationships between internet addiction, smartphone addiction, sleep quality, and academic performance among high-school students

SUMMARY OBJECTIVE: In this study, we aimed to evaluate the relationships between Internet addiction, smartphone addiction, sleep quality, and academic success. METHODS: In this cross-sectional study, high-school students were surveyed to evaluate sleep quality, Internet addiction, and smartphone addiction. Students were queried about their demographics, and grade averages from the previous term were taken as an indicator of academic success. RESULTS: A total of 1,959 students were enrolled in this study, with 1,034 (52.8%) girls and 925 (47.2%) boys, and the median age of the participants was 16 (13-21) years. Multivariate analyses found that poor sleep quality in students who did not have breakfast before going to school was 1.58 times higher than those who did (p<0.001). Students who stayed in a dormitory had 1.79 times more poor sleep quality than those who stayed with their family, and a one-unit increase in the total score of the Young's Internet Addiction Test short form resulted in a 1.08-fold increase (both, p<0.001). CONCLUSION: Our study has shown that students' sleep quality was predicted to be lower if they stayed in a dormitory and skipped breakfast. In addition, Internet and smartphone addictions have a negative effect on sleep quality and academic performance.

A microscope in your pocket: can smartphones be used to perform microsurgery?

ABSTRACT Purpose: To evaluate the use of the latest generation smartphone camera in performing arterial microanastomosis in rats. Methods: Ten Wistar rats were divided into 2 groups and underwent anastomosis of the right carotid artery with the aid of magnification from a microscope (group M) and a smartphone camera (group S), to compare patency in 72 hours, as well as to measure the weight of the animals, diameter of the carotid arteries and anastomosis time. Results: There was no statistical difference between the weight of the animals or the diameter of the carotid arteries. There was a statistical difference for the time spent on anastomoses, which was greater in group S, with higher rates of thrombosis (p < 0.05). Conclusions: Although our patency and anastomosis time results were statistically lower in the smartphone group, there was success in some cases. As the segment continues to progress, it is likely that the results will improve in line with the evolution of camera technology.

Accuracy of a smartphone-assisted novel labeling method for marking target axial position in cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the convenience and accuracy of a novel smartphone-assisted “any-point two-step method” for finding the target axial position in cataract phacoemulsification combined with intraocular lens(IOL)implantation.METHODS: Prospective observational study. A total of 62 cases(62 eyes)of patients with age-related cataracts who underwent cataract phacoemulsification combined with IOL implantation in our hospital from October 2021 to April 2022 were selected. They were randomly divided into two groups: 31 cases(31 eyes)in the control group were applied with the “traditional two-step method” using slit lamp to mark the target axial position of the IOL, and 31 cases(31 eyes)in the experimental group were applied with the smartphone-assisted “two-step method” to mark the target axial position of the IOL. The Callisto eye navigation system was used as a standard reference, and the deviation of the reference marking point(deviation-1), the deviation of the target axial marking point(deviation-total), and the deviation of the angle from the reference marking point to the target axial marking point(deviation-2)were calculated and recorded as the preoperative axial marking time.RESULTS:Both deviation-1 and deviation-total values were lower in the experimental group than those in the control group(1.06°±1.39° vs 2.48°±2.23°, 1.77°±1.54° vs 2.81°±1.58°, all P&#x003C;0.01), but there was no significant difference in the deviation-2 values between the two groups(1.35°±1.40° vs 1.48°±1.79°, P&#x003E;0.05). The preoperative axial marking took shorter time in the experimental group than in the control group(1.77±1.70 min vs 2.88±3.20 min, P&#x003C;0.01).CONCLUSION: The smartphone-assisted “any-point two-step method” for finding the target axial position in cataract phacoemulsification combined with IOL implantation is simple, time-saving, and accurate compared with the “traditional two-step method”.

Smartphone addiction and postural alterations in the cervical region in adolescents / Dependência do smartphone e alteração postural da região cervical de adolescentes

ABSTRACT Objective: To evaluate smartphone addiction and postural alterations in the cervical region in adolescents. Methods: A cross-sectional study with 281 adolescents (15 to 19 years old), attending the 1st to the 3rd grades of High School, carried out between September and October 2019 in the city of Fortaleza, Ceará, Brazil. Data collection took place in two stages. In the first, they answered four self-administered questionnaires: sociodemographic questionnaire, health conditions and smartphone use, Nordic Musculoskeletal Symptom Questionnaire (NMQ), Self-Report Questionnaire (SRQ-20) and the Smartphone Addiction Inventory (SPAI-BR). In the second stage, they were submitted to photogrammetry using the Postural Assessment Software (SAPO) and anthropometric assessment (weight and height). The software SPSS Statistics version 23.0 was used for data analysis. Results: Of the total number of adolescents, 63.3% (n=178) showed smartphone addiction, using it for 5.8 hours (±3.5) during the week and 8.7 (±4.0) hours on the weekend. When analyzing postural alignment in the anterior view, a significant reduction in the lateral head tilt was observed when typing on the smartphone (p=0.002) compared to the anatomical position (baseline). In the lateral view, an increase in head anteriorization was observed during smartphone use (p<0.05). There was an association between smartphone addiction and head anteriorization (p<0.05). Conclusions: The use of the smartphone in the typing position causes postural alterations in the cervical region, especially in adolescents with smartphone addiction. Therefore, health promotion measures that alert adolescents to the adverse effects caused by prolonged smartphone use are necessary.

Na primeira, eles responderam a quatro questionários autoaplicáveis: questionário sociodemográfico, condições de saúde e uso do smartphon e, Questionário Nórdico de Sintomas Musculoesqueléticos (NMQ), Self-Report Questi onnaire (SRQ-20) e o Smartphone A ddiction Inventory (SPAI-BR). Na segunda etapa, foram submetidos a fotogrametria pelo Software de Avaliação Postural (SAPO) e avaliação antropométrica (peso e altura). Para a análise dos dados, foi utilizado o SPSS Statistics versão 23.0. Resultados: Do total, 63,3% (n=178) dos adolescentes apresentaram dependência do smartphone, com o uso de 5,8 horas (±3,5) durante a semana e 8,7 (±4,0) no fim de semana. Ao analisar o alinhamento postural na visão anterior, observou-se redução significativa da inclinação lateral de cabeça ao digitar no smartphon e (p=0,002) comparado à posição anatômica (baseline). Na visão lateral foi constatado aumento da anteriorização de cabeça durante o uso do smartphon e (p<0,05). Houve associação da dependência do smartphone com a anteriorização de cabeça (p<0,05). Conclusões: O uso do smartphone na posição de digitação causa alteração postural na região cervical, destacadamente naqueles que apresentam dependência do dispositivo. Dessa forma, são necessárias medidas de promoção de saúde que alertem os adolescentes sobre os efeitos adversos causados pelo uso prolongado do smartphone.

Accuracy of an artificial intelligence-based mobile application for detecting cataracts: Results from a field study

Purpose: To assess the accuracy of e?Paarvai, an artificial intelligence?based smartphone application (app) that detects and grades cataracts using images taken with a smartphone by comparing with slit lamp?based diagnoses by trained ophthalmologists. Methods: In this prospective diagnostic study conducted between January and April 2022 at a large tertiary?care eye hospital in South India, two screeners were trained to use the app. Patients aged >40 years and with a best?corrected visual acuity <20/40 were recruited for the study. The app is intended to determine whether the eye has immature cataract, mature cataract, posterior chamber intra?ocular lens, or no cataract. The diagnosis of the app was compared with that of trained ophthalmologists based on slit?lamp examinations, the gold standard, and a receiver operating characteristic (ROC) curve was estimated. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were computed. Results: The two screeners used the app to screen 2,619 eyes of 1,407 patients. In detecting cataracts, the app showed high sensitivity (96%) but low specificity (25%), an overall accuracy of 88%, a PPV of 92.3%, and an NPV of 57.8%. In terms of cataract grading, the accuracy of the app was high in detecting immature cataracts (1,875 eyes, 94.2%), but its accuracy was poor in detecting mature cataracts (73 eyes, 22%), posterior chamber intra?ocular lenses (55 eyes, 29.3%), and clear lenses (2 eyes, 2%). We found that the area under the curve in predicting ophthalmologists’ cataract diagnosis could potentially be improved beyond the app’s diagnosis based on using images only by incorporating information about patient sex and age (P < 0.0001) and best?corrected visual acuity (P < 0.0001). Conclusions: Although there is room for improvement, e?Paarvai app is a promising approach for diagnosing cataracts in difficult?to?reach populations. Integrating this with existing outreach programs can enhance the case detection rate.

A pilot non-randomized trial of smartphone-based anaglyph system for treatment of adult amblyopia through VR (Virtual Reality)

Purpose: To evaluate the effectiveness of amblyopia treatment through a smartphone?based anaglyph system by virtual reality (VR) in adult patients. Methods: A total of 10 subjects diagnosed with anisometropic amblyopia were enrolled during the study period. Best Corrected Visual Acuity (BCVA), stereoacuity, and contrast acuity were evaluated during three visits (at presentation, 3 months and 6 months) of smartphone?based anaglyph video run in the VR mode. All the amblyogenic factors including stereopsis, color vision, and contrast acuity were compared using Friedman two?way analysis of variance. Statistical significance was considered if P < 0.05. Results: Mean BCVA in amblyopic eye improved significantly from a logMAR value of 0.73 ± 0.64 before Virtual reality vision therapy (VRVT) to a post?training VRVT value of 0.48 ± 0.44 (P < 0.01). Mean stereoacuity changed from a value of 560.00 ± 301.58 before VRVT to a value of 263.00 ± 143.58 seconds of arc after training (VRVT) (P < 0.01). Mean accommodation changes from a value of 15.00 ± 7.40 before training or VRVT to value of 12.60 ± 6.10 cm after training (P < 0.01). Mean contrast acuity changes from a value of 1.21 ± 0.72 at presentation to a value of 1.52 ± 0.49 log unit after VRVT. Conclusion: A smartphone?based anaglyph system using VR vision therapy appears to be an effective treatment option for amblyopia in adults.

The role of mobile teledermoscopy in skin cancer triage and management during the COVID-19 pandemic

The unprecedented onset of the COVID-19 crisis poses a significant challenge to all fields of medicine, including dermatology. Since the start of the coronavirus outbreak, a stark decline in new skin cancer diagnoses has been reported by countries worldwide. One of the greatest challenges during the pandemic has been the reduced access to face-to-face dermatologic evaluation and non-urgent procedures, such as biopsies or surgical excisions. Teledermatology is a well-integrated alternative when face-to-face dermatological assistance is not available.Teledermoscopy, an extension of teledermatology, comprises consulting dermoscopic images to improve the remote assessment of pigmented and non-pigmented lesions when direct visualisation of lesions is difficult. One of teledermoscopy’s greatest strengths may be its utility as a triage and monitoring tool, which is critical in the early detection of skin cancer, as it can reduce the number of unnecessary referrals, wait times, and the cost of providing and receiving dermatological care. Mobile teledermoscopy may act as a communication tool between medical practitioners and patients. By using their smartphone (mobile phone) patients can monitor a suspicious skin lesion identified by their medical practitioner, or alternatively self-detect concerning lesions and forward valuable dermoscopic images for remote medical evaluation. Several mobile applications that allow users to photograph suspicious lesions with their smartphones and have them evaluated using artificial intelligence technology have recently emerged. With the growing popularity of mobile apps and consumer-involved healthcare, this will likely be a key component of skin cancer screening in the years to come. However, most of these applications apply artificial intelligence technology to assess clinical images rather than dermoscopic images, which may lead to lower diagnostic accuracy. Incorporating the direct-to-consumer mobile dermoscopy model in combin

Fundoscopy in the smartphone age: current ophthalmoscopy methods in neurology / A fundoscopia na era dos smartphones: métodos atuais de oftalmoscopia na neurologia

Abstract The observation of the human retina in vivo began in 1851 after the invention of the first ophthalmoscope by the German physicist Hermann von Helmholtz. In the following decades, direct and indirect ophthalmoscopy, with the use of ophthalmoscopes and condensing lenses, respectively, became part of the clinical examination, especially in ophthalmology and neurology. Today, over 170 years later, many ophthalmoscopes and condensing lenses exist on the market. Nevertheless, ophthalmoscopy is still not widely adopted as part of the physical exam of general practitioners, and the teaching of ophthalmoscopy in medical school remains challenging. Studies have shown that students prefer using newer ophthalmoscope models or condensing lenses during training, but most do not feel confident in performing ophthalmoscopy afterwards, regardless of the models used. Also, few students acquire ophthalmoscopes for their future practice, and clinical trials have not clearly demonstrated superiority of newer ophthalmoscope models over the conventional ones in diagnostic accuracy. The technological improvement of smartphone cameras in recent years has made it feasible to photograph the fundus of the eye using ophthalmoscopes or condensing lenses, reducing the need for retinographs and similar equipment. Smartphone assisted indirect fundoscopy is becoming increasingly popular. This approach allows adequate identification of the structures of the fundus, is cost-efficient, easy to implement, and permits easy recording and sharing of the images obtained, which is useful for case discussions and medical teaching. However, controlled clinical trials validating this method in the evaluation of optic nerve pathologies are needed.

Resumo A observação da retina humana in vivo começou em 1851, após a invenção do primeiro oftalmoscópio pelo físico alemão Hermann von Helmholtz. Nas décadas seguintes, a oftalmoscopia direta e indireta, com o uso de oftalmoscópios e lentes condensadoras, respectivamente, tornou-se parte do exame clínico, especialmente em oftalmologia e neurologia. Hoje, mais de 170 anos depois, diversos oftalmoscópios e lentes condensadoras estão disponíveis no mercado. No entanto, a oftalmoscopia ainda não é amplamente realizada no exame físico de médicos generalistas e o ensino da oftalmoscopia na faculdade de medicina ainda é desafiador. Estudos mostram que estudantes preferem usar modelos novos de oftalmoscópio ou lentes condensadoras durante seu treinamento, porém a maioria dos estudantes não se sente suficientemente confiante em realizar oftalmoscopia mais tarde, mesmo quando utilizam os modelos mais novos. Além disso, poucos alunos adquirem oftalmoscópios para sua prática futura, e ensaios clínicos não demonstraram uma clara superioridade dos novos modelos de oftalmoscópio em relação ao modelo convencional em acurácia diagnóstica. O aperfeiçoamento tecnológico das câmeras de smartphones nos últimos anos tornou possível fotografar o fundo do olho utilizando oftalmoscópios ou lentes condensadoras, reduzindo a necessidade de retinógrafos e equipamentos similares. A fundoscopia indireta realizada com smartphones vem se tornando cada vez mais popular. Esta abordagem permite a adequada identificação das estruturas do fundo do olho, é custo-efetiva, fácil de implementar e permite o fácil registro e compartilhamento das imagens obtidas, o que é útil para discussão de casos clínicos e para o ensino médico. Entretanto, ensaios clínicos controlados para a validação deste método na avaliação de patologias do nervo óptico são necessários.
