Combining External Medical Knowledge for Improving Obstetric Intelligent Diagnosis: Model Development and Validation
Authors: Zhang Kunli , Cai Linkun , Song Yu , Liu Tao , Zhao Yueshu
Published: May 2021

Background

Data-driven medical health information processing has become a new development trend in obstetrics. Electronic medical records (EMRs) are the basis of evidence-based medicine and an important information source for intelligent diagnosis. To obtain diagnostic results, doctors combine clinical experience and medical knowledge in their diagnosis process. External medical knowledge provides strong support for diagnosis. Therefore, it is worth studying how to make full use of EMRs and medical knowledge in intelligent diagnosis.

Objective

This study aims to improve the performance of intelligent diagnosis in EMRs by combining medical knowledge.

Methods

As an EMR usually contains multiple types of diagnostic results, the intelligent diagnosis can be treated as a multilabel classification task. We propose a novel neural network knowledge-aware hierarchical diagnosis model (KHDM) in which Chinese obstetric EMRs and external medical knowledge can be synchronously and effectively used for intelligent diagnostics. In KHDM, EMRs and external knowledge documents are integrated by the attention mechanism contained in the hierarchical deep learning framework. In this way, we enrich the language model with curated knowledge documents, combining the advantages of both to make a knowledge-aware diagnosis.

Results

We evaluate our model on a real-world Chinese obstetric EMR dataset and showed that KHDM achieves an accuracy of 0.8929, which exceeds that of the most advanced classification benchmark methods. We also verified the model’s interpretability advantage.

Conclusions

In this paper, an improved model combining medical knowledge and an attention mechanism is proposed, based on the problem of diversity of diagnostic results in Chinese EMRs. KHDM can effectively integrate domain knowledge to greatly improve the accuracy of diagnosis.

Published: May 2021

Background

Noninvasive and cuffless approaches to monitor blood pressure (BP), in light of their convenience and accuracy, have paved the way toward remote screening and management of hypertension. However, existing noninvasive methodologies, which operate on mechanical, electrical, and optical sensing modalities, have not been thoroughly evaluated in demographically and racially diverse populations. Thus, the potential accuracy of these technologies in populations where they could have the greatest impact has not been sufficiently addressed. This presents challenges in clinical translation due to concerns about perpetuating existing health disparities.

Objective

In this paper, we aim to present findings on the feasibility of a cuffless, wrist-worn, pulse transit time (PTT)–based device for monitoring BP in a diverse population.

Methods

We recruited a diverse population through a collaborative effort with a nonprofit organization working with medically underserved areas in Georgia. We used our custom, multimodal, wrist-worn device to measure the PTT through seismocardiography, as the proximal timing reference, and photoplethysmography, as the distal timing reference. In addition, we created a novel data-driven beat-selection algorithm to reduce noise and improve the robustness of the method. We compared the wearable PTT measurements with those from a finger-cuff continuous BP device over the course of several perturbations used to modulate BP.

Results

Our PTT-based wrist-worn device accurately monitored diastolic blood pressure (DBP) and mean arterial pressure (MAP) in a diverse population (N=44 participants) with a mean absolute difference of 2.90 mm Hg and 3.39 mm Hg for DBP and MAP, respectively, after calibration. Meanwhile, the mean absolute difference of our systolic BP estimation was 5.36 mm Hg, a grade B classification based on the Institute for Electronics and Electrical Engineers standard. We have further demonstrated the ability of our device to capture the commonly observed demographic differences in underlying arterial stiffness.

Conclusions

Accurate DBP and MAP estimation, along with grade B systolic BP estimation, using a convenient wearable device can empower users and facilitate remote BP monitoring in medically underserved areas, thus providing widespread hypertension screening and management for health equity.
Pharmacological interventions for the management of cancer-related fatigue among cancer survivors: systematic review and meta-analysis (Preprint)
Authors: Sun Xuemei , Chen Yancong , Cheung William , Wu Irene , Xiao Fang , Chung Vincent
Published: May 2021

BACKGROUND

Background: Current guidelines have different recommendations on applying pharmacological interventions for managing cancer-related fatigue (CRF) among cancer survivors.

OBJECTIVE

Objective: This systematic review aims to synthesize clinical evidence on pharmacological interventions for managing CRF.

METHODS

Methods: Five databases were searched for potential Randomized controlled trials (RCTs) from their inception till October 2020. RCTs assessing the effect of pharmacological treatments for CRF among cancer survivors were considered eligible. Clinical significance was determined by comparing the estimated effect with that of minimal important difference (MID). The risk of bias of included RCTs were appraised using the Cochrane risk of bias tool for randomized trials 2.

RESULTS

Results: A total of 15 RCTs (1238 participants) were included. Majority presented some concerns of bias arising from the randomization process and selection of the reported result. Meta-analysis showed that psychostimulant and wakefulness agents had statistically significant while clinical insignificant effect on the treatment of CRF (pooled weighted mean difference (WMD): 2.8, 95% confidence interval (CI): 0.2 to 5.4, I2: 0%, 3 RCTs, MID: 3.0 to 6.0). Three natural products, including Renshen Yangrong Tang (mean difference (MD): -16.1, 95% CI: -8.9 to -23.3, MID: -17.3 to -11.4), Tualang honey (MD: 11.2, 95% CI: 7.1 to 15.3, MID: 3.0 to 6.0) and Shenmai injection plus Peptisorb (MD: -1.6, 95% CI: -2.1 to -1.1, MID: -1.1 to -0.8) demonstrated statistically and clinically significant effect in reducing CRF.

CONCLUSIONS

Conclusions: Existing evidence showed promising effects of three natural products in reducing CRF among cancer survivors. The results from this study need to be further confirmed with well-designed and adequate powered RCTs that use validated instruments for the measurement of CRF.

CLINICALTRIAL

The protocol of this systematic review has been registered in PROSPERO (registration number: CRD42018102347).
Smartphone tilt as a measure of well-being? Evidence from two experience sampling studies (Preprint)
Authors: Kuhlmann Tim , Reips Ulf-Dietrich
Published: May 2021

BACKGROUND

Smartphone usage is increasing around the globe. Smartphones offer considerable opportunities to researchers implementing experience sampling designs. Besides convenient gathering of self-report data, the availability of objective sensor data promises advantages for data collection.

OBJECTIVE

Previous research has shown the relation between body posture and well-being as well as an association between smartphone sensor data and posture. We investigated the association of the smartphone’s objective tilt measure with self-reported well-being in the field.

METHODS

Two experience sampling studies with 98 and 261 participants were conducted. They included self-reported measures of well-being and objective sensor gathered at the same points in time. The sample included Android and iOS smartphones.

RESULTS

Results of Study 1 show a within-person association between deviation from the usual tilt and well-being, t(3392)=-3.9, p<.001, d=.13. In Study 2 this association was only shown for Android users, t(3389)=-2.20, p=.03, d=.08, but not for iOS users. Comparison of the groups did reveal differences in the distribution of the sensor measured tilt.

CONCLUSIONS

An association between subjective well-being and smartphone sensor data was shown, but not consistently across devices and studies. Possible explanations for the differing results by smartphone platform include heterogeneity of the hardware implemented and differences in the software sensor values. Advice on precautions to consider when implementing app studies on differing devices and platforms in the wild are given. Implications for future studies, including objective validation of sensor data, are also discussed.

Bit by Bit: Using Design-Based Research to Improve the Health Literacy of Adolescents
Authors: Subramaniam Mega , St. Jean Beth , Taylor Natalie Greene , Kodama Christie , Follman Rebecca , Casciotti Dana
Published: May 2021

Background

Although a low health literacy level has been found to be among the most powerful predictors of poor health outcomes, there is very little research focused on assessing and improving the health literacy skills of adolescents, particularly those from socioeconomically disadvantaged backgrounds. The vast majority of existing research focuses solely on reading comprehension, despite the fact that health literacy is actually a multifaceted concept, which entails many different types of skills.

Objective

The aim of this paper is to first mine existing literature to identify the many different skills that have been posited to constitute health literacy, and then, using this collection of skills as an overarching structure, to highlight the challenges that disadvantaged youth participating in our HackHealth after-school program encounter as they identify and articulate their health-related information needs, search for health-related information online, assess the relevance and credibility of this information, and manage and make use of it.

Methods

We utilized the design-based research method to design, implement, and revise our HackHealth program. To collect data regarding HackHealth participants’ health literacy skills and associated challenges, we used a variety of methods, including participant observation, surveys, interviews, focus groups, and logging of Web browser activities. We also collected data through specialized instructional activities and data collection forms that we developed for this purpose. Quantitative and qualitative techniques were used to analyze this data, as well as all of the artifacts that each student produced, including their final projects.

Results

We identified the various challenges that the 30 HackHealth participants faced in completing various health-related information activities during the course of the program. Based on these findings, we describe important implications for working with youth from socioeconomically disadvantaged backgrounds, how to assess and improve their health literacy skills, and offer specific recommendations for health literacy instruction aimed at this population.

Conclusions

With an increased societal focus on health and a shift from viewing patients as passive recipients of medical care to viewing them as active arbiters of their own health, today’s youth need to possess an array of health literacy skills to ensure that they can live long and healthy lives. Working with adolescents to help them develop and practice these skills will also help to break the cycle between poor health literacy and poor health outcomes, thereby reducing health disparities and improving the long-term outlook for the health of our nation.

Ki Ageng Gribig No.5 Malang Postal Code 65173. Having a vision that is "The realization of community empowerment, population control and the realization of gender equality and protection of women and children". BKBPM also mediates the strategy and policy direction planned by the Malang city government, namely increasing the empowerment of the poor, increasing the empowerment and protection of women and children. As well as improving the quality of family planning and family welfare (DP3AP2KB, 2016).

The results of the discussion stated that the number of family planning participants in RW 08 was 329 or 54.92 percent of the number of PUS (couples of childbearing age) of 599. The most enjoyed contraceptive method is an IUD of 98 or 29.78 percent. Whereas for MKJP KB (long-term method of family planning contraception) participants (Long Term Contraception Method) by 13 or 40.42 percent, and the most usage was NON MKJP which was 59.74 percent.

Based on the Gender Perspective, only 66 of the 329 KB participants or only 20% of the male participants are involved. This is based on the results of interviews in the family many  mothers who  do  not  approve  of her husband  using  the  Vasectomy  Contraception method, also due to suspicion if the husband uses it will be misused misused on other women (anonymous),  other than that the causes of Unmet need factors: Side effects on health, prohibitions from spouse or husband, discomfort, costs to be incurred, do not want to bother, subjective experience does not use contraception does not occur in pregnancy.

Published: May 2021

Background: Traumatic brain injury is a severe condition in elder patients. Young patients usually have better prognosis compared to the elderly. Head trauma might represent an initial event that leads to death in this population. Objective: To evaluate was to evaluate the epidemiological profile of elderly patients operated on chronic subdural hematoma (CSDH). Methods: This is a descriptive, observational and retrospective case series. The use of anticoagulant and antiplatelet drugs, length of hospital stay, mortality and CSDH recurrence, among others, were the evaluated variables. Results: A total of 328 patients had their records assessed. Patients younger than 60 years formed group 1 (n=102) and those older than 60 years formed group 2 (n=226). Ageing is correlated to higher mortality. Acetylsalicylic acid and anticoagulant drugs usage in both groups did not correlate to worse outcomes. In group 2, there were 33 deaths during hospital stay (14.6%) and 14 deaths within one year after surgery (6.2%). Only one death was registered in group 1. Conclusion: Ageing is an important isolated prognostic factor.

Authors: Leite Filho Cesar Auladino , Dantas Lara Inês Martins , Nogueira Felipe Vanderley , Rodrigues Vinicius Bessa
Published: May 2021

Introdução: O acidente vascular encefálico (AVE) é importante causa de morbimortalidade mundialmente. O tipo isquêmico é o mais comum, o qual tem potencial reversível com o uso de trombolíticos, porém com janela terapêutica de seis horas, o que em muitos locais resulta em impossibilidade terapêutica. Devido a isso, surgiu a trombectomia mecânica que expande esse tempo limite para 24 horas. Metodologia: Realizou-se um levantamento de dados nas bases eletrônicas PubMed, SciELO e DynaMed. Foram utilizados os descritores em ciências da saúde (DECS) e os termos: “trombectomia”, “AVE” e “anatomia” sendo selecionados trabalhos que contemplam o tratamento de AVE com o uso de trombectomia correlacionando anatomia e contexto clínico. Resultados: A trombectomia mecânica (TM) deve ser realizada em AVE isquêmico com menos de 24 horas do início dos sintomas, idade maior ou igual a 18 anos e ausência de incapacidade pré-AVE. Deve-se realizar exame angiográfico que identifique uma oclusão que deve ser da artéria anterior. Em outros casos, ela pode ser realizada, porém não como primeira linha. Conclusão: Os trabalhos concordam que a MT trouxe mudanças significativas para o AVC isquêmico, mas ainda são necessários mais estudos sobre o assunto, além de treinamento dos profissionais atuantes nesse cenário.

Published: May 2021

The central nervous system (CNS) is a common site of metastasis for a number of malignant tumors. Lung, breast, skin (melanoma), kidney and colorectal neoplasms form the most common group of primary sites that send distant metastases to the CNS, always via the hematogenous route. Delayed diagnosis, tumor aggressiveness, and failed primary treatment contribute to this evolution of secondary brain involvement. CNS metastases of salivary gland neoplasms are rare, with few cases reported in the literature. In the case here presented, a young male patient presents a peculiar situation of a carcinoma ex pleomorphic adenoma that developed metastasis to the brain by contiguity through the facial nerve. The outcome, as expected, was poor and the patient died.

Authors: Sousa Campos Fernanda Myllena , Castro Cabral Diego Arthur , Ferreira Lobão Carlos Augusto
Published: May 2021

Os cistos epidermoides do sistema nervoso central (SNC) são condições incomuns e apresentam-se em sítios variáveis, como a díploe do crânio, sendo esta a localização mais rara. Esses cistos são tumores de crescimento lento, semelhante ao padrão de crescimento das células epidérmicas da pele, geralmente localizados fora da linha média, nos ossos do crânio frontal, temporal ou parietal. Seu tratamento ideal consiste na remoção completa da lesão, através de craniotomia (ou craniectomia) sem comprometer a condição neurológica do paciente. Apresentamos o caso de um homem de 22 anos com diagnóstico histopatólogico de cisto epidermoide intradiplóico que foi submetido ao tratamento de escolha.
Para centralizar o periférico: personagem, raça e classe em Aquarius
Authors: Marques Ribeiro Luís Henrique , Mousinho Magalhães Luiz Antonio
Published: May 2021

O filme Aquarius, de Kleber Mendonça Filho, não tematiza explicitamente a questão racial. Contudo, a forma secundária, descolada do eixo principal da narrativa, parece obter um efeito centralizante para o entendimento de camadas de sentido enquanto obra que pensa a realidade brasileira. As relações que a personagem principal, de sugestivo nome Clara, estabelece com as personagens empregadas domésticas no filme, parece indicar a construção daquilo que pretendemos chamar de representações raciais complexas no cinema brasileiro.
Universo sertanejo: amor traído e Bolsonaro
Authors: França Vera Regina Veiga , Vieira Vanrochris Helbert
Published: May 2021

Este texto buscou encontrar confluências entre dois movimentos percebidos no universo da música sertaneja nos últimos anos: no cenário político, o apoio quase total dos cantores ao candidato Bolsonaro, em nome da ordem e do uso de armas; nas músicas, a temática dos relacionamentos afetivo-sexuais com ênfase no viés da “sofrência”, do eu lírico que sofre a separação, enfrenta relações instáveis e mulheres mais fortes. Zizek, através do conceito (lacaniano) de point de capiton, ajudou-nos a entender a coesão de elementos ideológicos díspares dentro de uma formação discursiva conservadora, delineada por um modelo de masculinidade.
Aspectos motivacionales para generar actividades cerebrales óptimas en el proceso de aprendizaje en un Ambiente Virtual de Aprendizaje
Authors: Bucheli-López Héctor Andrés , Rojas-Arango Bibiana Patricia , Vergara-Henao Sandra María , Rodríguez-Niño María Consuelo
Published: May 2021

Este estudio se centró en identificar la variedad de aspectos motivacionales que se pueden implementar en los Ambientes Virtuales de Aprendizaje. Se utilizó el paradigma de investigación cuantitativa, a partir del modelo experimental, donde la variable independiente es el estímulo (motivación) y la variable dependiente es el resultado obtenido en los campos cerebrales que mostraron activación. Para el análisis estadístico se utilizó la suite de office Microsoft Excel con la herramienta de análisis de datos. El estudio permitió observar un aumento leve de la actividad cerebral en el área prefrontal del hemisferio derecho, moderado en las áreas temporal y parietal del mismo hemisferio, y leve en el área central y las áreas frontales en ambos hemisferios. El área frontal está relacionada con la construcción y diseños de objetos y figuras, al tiempo que interviene en la memoria de trabajo para el material visual. Esto indica que las personas deben ser estimuladas de diferentes formas, entre las que se encuentran los aspectos motivacionales, para generar estados óptimos en el cerebro para los procesos de aprendizaje. Por lo tanto, se pueden definir estrategias tecnopedagógicas para el diseño de cursos que mejoren la atención, incidan en el aprendizaje significativo y garanticen la permanencia en la modalidad virtual.
Refazendo um trajeto: 10 anos de Semiologia – A teoria do Texto de Roland Barthes
Authors: Bellocchio Carolina Molinar , Pino Claudia Amigo
Published: May 2021

Este artigo parte da hipótese da virada de postura intelectual e escritural que Roland Barthes operou na década de 1960. Acreditamos que essa virada esteja ligada a uma nova maneira de Barthes se colocar em sua escritura, de incidir subjetivamente em sua produção, ligando a atividade acadêmica, profissional, a um trabalho de inscrição de subjetividade. Este trabalho pretende seguir algumas pegadas de modo a recompor o caminho trilhado por ele nesse período de 1961 a 1971-1972, no marco da década, de maneira específica o Seminário “10 anos de Semiologia – A teoria do Texto, oferecido na École pratique des hautes études. A fim de efeturamos tal análise, propomos refazer parte do trajeto empreendido por Barthes através da leitura de trechos de alguns textos, tais como os Elementos de Semiologia, Ensaios Críticos, A Aventura semiológica, Rumor da Língua e do seminário sobre Sarrasine de Balzac.
Charles S. Peirce – Precursor da virada não humana
Authors: Nöth Winfried
Published: May 2021

O artigo apresenta as ideias e os representantes principais (entre eles, Agamben, Derrida, Massumi) do movimento intelectual contemporâneo conhecido como a Virada Não Humana. Ele defende a tese de que a atual tendência de afastamento do antropocentrismo humanista em direção a novos horizontes filosóficos, que incluem reflexões sobre cognição, mentes e consciências humanas e não humanas, tem um precursor na filosofia e semiótica de Charles S. Peirce. Entre as ideias peircianas que prefiguram a ideia chave da Virada Não Humana de que os humanos deviam ser considerados como animais e os animais como seres racionais são o sinequismo e a semiótica da natureza, cujos descendentes contemporâneos são a linhas de pesquisa da zoossemiótica e a biossemiótica.

O espelho e o vidro
Authors: Silva Júnior Maurício Guilherme
Published: May 2021

O presente artigo busca analisar, comparativamente, o processo de construção do que aqui será chamado de “instantes imagéticos” em dois territórios narrativos aparentemente antípodas: a descrição ficcional do “ponto que concentra todos os pontos”, no conto “O Aleph”, do escritor argentino Jorge Luis Borges, e a construção editorial de reportagens diárias no Jornal Nacional (JN). Trata-se do primeiro movimento conceitual em torno de problematização a ser ampliada em outros tantos artigos, nos quais se pretende desenvolver investigações empíricas – sempre de modo comparado ao referido texto literário de Borges – acerca de coberturas jornalísticas específicas do JN e de telejornais de outras emissoras.
Análise Crítica da Narrativa aplicada ao radiojornalismo: uma proposta de adaptação metodológica
Authors: Quadros Mírian Redin de , Amaral Márcia Franz
Published: May 2021

Este artigo propõe uma aproximação teórica entre a definição prática de narrativa radiofônica e a perspectiva teórico e metodológica que interpreta o jornalismo como narrativa, articulando preceitos da Hermenêutica e da Pragmática. O objetivo é traçar apontamentos que conduzam a uma nova abordagem para os estudos de rádio, ao considerar a narrativa não somente como gênero ou formato textual, mas como um processo de ordenamento e atribuição de sentidos às experiências humanas. O texto toma como referência a Análise Crítica da Narrativa, proposta por Motta (2013), e sua divisão metodológica da narrativa em três planos: o plano da expressão, da estória e da metanarrativa. A partir destas instâncias analíticas, o artigo discute as características que diferenciam as narrativas radiofônicas das narrativas configuradas nos meios impressos, indicando potencialidades e especificidades para a aplicação metodológica da Análise da Narrativa em estudos de rádio.

Educação, jogos, gamificação
Authors: Pimenta Maria Alzira de Almeida , Dos Santos Roger
Published: May 2021

No contexto atual a ideia de gamificação ganhou lugar nas discussões sobre educação, especialmente, sobre práticas pedagógicas e aprendizagem. Além dos mais conhecidos jogos, praticados há mais de um século, a mídia e os videogames alargaram a seara dos jogos. Neste artigo, são apresentados elementos para se refletir e compreender como a gamificação e suas reverberações, na sociedade que abarcou a comunicação pela internet como parte de sua cultura, impactam a educação. O jogador nº 1, a ficção pensada por Cline (2018), sintetiza o conceito da cultura da convergência (JENKINS, 2009) que traduz, para a contemporaneidade, a multiplicidade de veículos e de linguagens aportadas na diversão pela interatividade. A ludicidade, presente nos games, vem ganhando lugar nas salas de aula e é preciso entendê-la em sua potencialidade e limitações.

Published: May 2021

This study presents energy, entropy, and exergy analyses of Al2O3-Cu/water hybrid nanofluid flow in a trapezoidal cross-sectioned channel under a turbulent regime (﻿104<Re<105) for the first time. Understanding the main source of the entropy generation along the channel, also obtaining the total entropy variation of hybrid nanofluid comparing to single nanofluids (Al2O3/water and Cu/water) and base fluid is pursued objective. In other to perform these aforementioned analyses, a realistic model, in which all formulas are derived, is developed and thermodynamic concepts such as exergy efficiency and exergy destruction for hybrid nanofluid flow in a non-circular cross-sectioned channel are discussed for the first time. Results obtaining from the analyses of both hybrid and single nanofluids have been compared and discussed for volumetric concentrations of 1.0% and 2.0%. As a result, it is obtained that 2.0% volume concentration hybrid nanofluid offers the best convective heat transfer performance with 34% enhancement and best exergetic performance. Furthermore, hybrid nanofluid has the lowest entropy generation value.

Chenopodium quinoa (quinoa) is considered a superfood, as it has
favourable nutrient composition and is gluten free. Quinoa has high
tolerance to several abiotic stresses, i.e. salinity, water deficit
(drought) and cold. The tolerance mechanisms are yet to be elucidated.
Quinoa has Epidermal Bladder Cells (EBCs) that densely cover the shoot
surface, particularly the younger parts of the plant. Here, we report on
the EBC’s primary and secondary metabolomes, as well as the lipidome in
response to abiotic stresses. EBCs were isolated from plants after cold,
heat, high-light, water deficit and salt treatments. We used untargeted
Gas Chromatography-Mass Spectrometry (GC-MS) to analyse metabolites and
untargeted and targeted Liquid Chromatography-MS (LC-MS) for lipids and
secondary metabolite analyses. We identified 64 primary metabolites,
including sugars, organic acids and amino acids, 19 secondary
metabolites, including phenolic compounds, betanin and saponins and 240
lipids categorized in five groups including glycerolipids and
phospholipids. Although we found only few changes in the metabolic
composition of bladders in response to abiotic stresses, metabolites
related with heat, cold and high-light treatments, but not salt stress,
were changed significantly. Na concentrations were
low in EBCs with all treatments, and approximately two orders of
magnitude lower than K concentrations.

Authors: Tahra Ahmet , Dinçer Murat , Onur Rahmi
Published: May 2021

Objective The Coronavirus pandemic has affected urological practice
worldwide. In this study, we aimed to evaluate functional urology
practice including outpatient clinic visits, routine examinations,
diagnostic procedures and surgical interventions with an online survey.
Method We conducted an online survey to evaluate Turkish urologists’
functional urology practices before and during the pandemic. In this
survey, we asked questions about the respondents’ place of work, being
part of a dedicated pandemic center, involvement with the pandemic and
an interest in functional urology. We also examined outpatient clinics,
routine examinations, diagnostic methods, and surgical practice before
and during the pandemic. Results A total of 152 urologists completed the
survey. The majority of the participants, (79.6%) were in tertiary
centers. Nearly one-third of respondents (32.2%) stated that more than
50% of their routine practice is related to functional urology. In
brief, 80.9% of the participants declared a decrease in the number of
outpatient visits for functional urology. 68.4% of the participants
declared a decrease in uroflowmetry practice, and 81.3% of had a
decrease in urodynamic studies performed. According to respondents,
92.1% stated a decrease in botulinum injections for the bladder, and
93.4% of the participants declared a decrease in anti-incontinence
surgery. Eighty-five percent of the participants declared a decrease in
prolapse surgery. One-hundred and twenty-eight participants (84.2%)
declared a decrease in surgery for benign prostate hyperplasia (BPH).
Only 28.9% of the participants responded that they diagnosed their
neuro-urology patients as they did prior to the pandemic. Conclusions
The daily practice of urology changed, and functional urology was one of
the most affected field. The large backlog of functional urology
patients is challenging and although conditions, diagnostic tools and
surgeries were classed as “benign”, we will have to face the effects
of patients’ Quality of life in the near future.

Introduction: The spatial thermodynamics of very high power-short
duration (vHPSD) radiofrequency (RF) application during pulmonary vein
isolation (PVI) in in-vivo model has not been well characterized. This
study was conducted to investigate the distance-temperature relationship
during vHPSD-RF ablation. Methods: PVI was performed using the vHPSD
catheter with the settings of 90W, RF time of 4 sec and 15mL/min
irrigation in a canine model. Catheter contact force (CF) of 10-20g was
defined as ‘normal’ and CF >20g as ‘firm’ CF. Tissue
temperature was monitored using thermocouples implanted at the surface
of the left atrial-pulmonary vein junction, left phrenic nerve, and the
luminal esophagus. PVI using a standard contact-force sensing catheter
(SCF) (settings of 35W, 30sec and 30mL/min irrigation) was performed for
comparison. Results: A total of 334 TC profiles in 4 animals was
investigated. Time to maximum tissue temperature (MTT) (6.0sec
[vHPSD/normal CF] vs. 30.5 sec [SCF/normal CF],
p<0.001; 8.0sec [vHPSD/firm CF] vs. 24.0sec [SCF/firm
CF], p=0.022) was shorter with vHPSD than in SCF groups. MTT within
10mm from catheter-tip was lower in vHPSD ablation with normal CF than
using SCF ablation (median 41.9°C [interquartile-range; 40.2-46.1]
vs. 49.5°C [45.9-56.2], p=0.013). The distance margin to keep the
MTT below 39ºC, 42ºC, and 50ºC were 4.9mm, 4.2mm, and 3.4mm,
respectively in the vHPDS group. This margin was larger (8.0mm, 6.6mm,
and 4.6mm) in the SCF group. Conclusion: Our study underscores that
vHPSD creates greater resistive heating than conventional catheter
ablation.

Authors: xie mingxing , Yuan Hongliang , Li Yuman , Wu Wenqian , Zhang Yongxing , Liu Manwei
Published: May 2021

Objective: This study was conducted to evaluate pre- and intraoperative
risk factors for 30-day mortality in patients with acute type A aortic
dissection (ATAAD). Methods: Three hundred thirteen patients with ATAAD
who underwent emergency surgery (264 men and 49 women; mean age, 48±10
years) were enrolled in our study. Preoperative and operative risk
factors for death were presented. Multivariable analysis was performed
to identify the influence of varying factors on 30-day mortality.
Results: Overall, 32 patients (10.2%) died within 30 days. Compared
with the surviving group, the deceased patients were more likely to have
tachycardia, elevated serum potassium levels, moderate to severe
pericardial effusion, suprasternal branch involvement, myocardial
ischemia, and lower-extremity ischemia. Regarding factors related to
surgery, the duration of surgery and cardiopulmonary bypass and
concomitant procedures of coronary artery bypass graft（CABG） were
greater in patients who died. In multivariate analysis, independent risk
factors were longer duration of surgery (odds ratio [OR]: 4.5,
p=0.001) and cardiopulmonary bypass (OR: 5.3, p=0.001), moderate to
severe pericardial effusion (OR: 3.3, p=0.017), suprasternal branch
involvement (OR: 4.9，p=0.002), and lower-extremity ischemia (OR: 7.6,
p＜0.001). Conclusions: Lower-extremity ischemia and suprasternal branch
involvement have the poorest outcomes. Moderate to severe pericardial
effusion could influence the outcome. Shorter duration of surgery is
associated with better outcomes. Key Words: acute type A aortic
dissection, surgery, mortality, risk factors

Authors: Obi-Egbedi Ogheneruemu , Hussayn Jamiu , Oluwatayo Isaac
Published: May 2021

The cocoa sector in Nigeria has experienced decline in production, yield, exports coupled with its inability to attain global standards and targets and, gradual loss of competitiveness at the world market. Trade liberalization was government’s panacea to the sector’s problem although, cocoa competitiveness remains an issue since liberalization. Therefore, the relationship between trade liberalization policy and competitiveness of Nigeria’s cocoa exports was examined in this study using data for the period 1961-2017. Cocoa market share was used to measure competitiveness while analytical tools employed were: ADF test, Johansen co-integration test and the vector error correction model (VECM). Market share, quantity of cocoa export and inflation rate were stationary at original level while others, at first difference. The co-integration test showed seven co-integrating equations. Trade liberalization policy was found to be an important driver of competitiveness. In addition, area harvested, production quantity and export quantity positively influenced competitiveness while world price of cocoa, interest rate on agricultural loans, exchange rate and trade liberalization influenced negatively. Therefore, appropriate trade policy formulation and implementation is recommended while, specific attention should be paid to monetary policies and cocoa production by the government.

Analysis of data from clinical cohorts, and more recently from human pancreatic tissue, indicates that reduced prohormone processing is an early and persistent finding in type 1 diabetes. In this article, we review the current state of knowledge regarding alterations in islet prohormone expression and processing in type 1 diabetes and consider the clinical impact of these findings. Lingering questions, including pathologic etiologies and consequences of altered prohormone expression and secretion in type 1 diabetes, and the natural history of circulating prohormone production in health and disease, are considered. Finally, key next steps required to move forward in this area are outlined, including longitudinal testing of relevant clinical populations, studies that probe the genetics of altered prohormone processing, the need for combined functional and histologic testing of human pancreatic tissues, continued interrogation of the intersection between prohormone processing and autoimmunity, and optimal approaches for analysis. Successful resolution of these questions may offer the potential to use altered prohormone processing as a biomarker to inform therapeutic strategies aimed at personalized intervention during the natural history of type 1 diabetes and as a pathogenic anchor for identification of potential disease-specific endotypes.
