Physical Insight into Ultra-low Desulfurization of Liquid Fuels using Sono-hybrid Fenton Reaction
Authors: Upadhyay Prachi , Chakma Sankar
Published: August 2023

The sulfur-containing hydrocarbons are the main source of SOx
and CO2
gas
emissions, which is a threat to the environment for sustainability development.
According to the US environment protection agency, the sulfur content should be
within the limit of 15 ppm and 30 ppm for diesel and gasoline, respectively. Also, a
couple of advanced techniques have been developed so far for the removal of sulfur
from fuels. Among these techniques, ultrasound-based advanced oxidation processes
have been found to be more efficient and effective for sulfur removal.
In this chapter, we have discussed the physical and chemical mechanism of ultrasound
based advanced oxidation processes including the influences of process parameters
such as pH, the concentration of sulfur, concentration of oxidant, presence of phase
transfer catalyst, oxalate ions, etc. Also, several hybrid techniques are discussed with
their advantages and disadvantages for obtaining ultra-low sulfur fuel.

HIV-infected and HIV-affected children experience grief from the death of their family, many caregiver transitions, and the potentially traumatic experience of living under stigma. Boy patient, 9 years old, Hindu, Balinese, single, not working, was consulted from the pediatric department and admitted in the Cempaka room of Prof. Dr. I.G.N.G. Ngoerah on April 6, 2023. From auto-anamnesis, he has a depressive mood, loss of interest and excitement, weight loss, fatigue or loss of energy, insomnia, psychomotor agitation, or retardation. The patient was diagnosed with Human Immunodeficiency Virus (HIV) in 2014 when he was a year and six months old. The patient lost his father in February 2023. The patient experienced depression caused by psychosocial stressors because of the loss of his father and was diagnosed with HIV. HIV-infected children are prone to get depression. One of the psychosocial stressors experienced by children with HIV is the prolonged mourning process due to the loss of a family member. Comprehensive treatment is needed in the form of psychopharmacology and psychotherapy. Family support is the most important thing in relieving symptoms of depression and increasing medication adherence.

Authors: Azalia Raslea , Sukiyono Ketut , Windirah Nola
Published: August 2023

Stabilization of food prices is still a strategic issue in Indonesia. This is because most Indonesians use their income mostly for food. Various publications reported that Indonesian food expenditure is approximately half of their income. Therefore, maintaining price stability, including beef and chicken meat price, is a significant policy to design. However, the continuous difficulty in predicting how beef and chicken meat prices behave is another reason for the importance of analyzing the price behavior of these two commodities. This research aims to respond to these problems by analyzing price fluctuations and price trends in beef and chicken meat commodities in Indonesia. The data used is monthly beef and chicken meat prices in Indonesia from January 2018 until December 2022, or 60 observations. Analysis of price fluctuations (instability) and trend analysis is applied. The results show that commodity chicken meat has a higher instability (fluctuation) than beef price. Both beef and chicken meat trend show a quadratic pattern, with an increasing trend for beef and a decreasing trend for chicken meat.

Authors: Islas-Hernández C. Sofia , Alvarado-Cárdenas Leonardo O.
Published: August 2023

Antecedentes y Objetivos: Spigelia es un género neotropical con cerca de 90 especies distribuidas desde los Estados Unidos de América hasta Argentina. La diversidad del género presenta una separación espacial entre un grupo en Norte-Centroamérica/Caribe (NA) y otro en Sudamérica (SA), cada uno con un importante centro de diversificación. Sin embargo, el conocimiento sistemático del grupo no ha sido actualizado en los últimos 10 años, por lo que el objetivo de este trabajo es generar una sinopsis sistemática para el género distribuido en la región NA.
Métodos: El trabajo se realizó a través de la búsqueda de información bibliográfica para obtener la historia taxonómica, así como trabajo de campo y revisión de material herborizado, a partir del cual se realizaron descripciones diagnósticas y mapas de distribución.
Resultados clave: Se encontraron 29 especies distribuidas en la región NA, lo que representa alrededor de 30% de la diversidad del género, en las zonas tropical y subtropical. En la región NA, Mesoamérica es una de las regiones en las que se concentra la diversidad vegetal, lo que la cataloga como hotspot. El trabajo incluye información novedosa sobre la morfología del grupo, como descripciones de los caracteres polínicos y carpológicos, claves de identificación por regiones en NA y mapas de distribución en el área de estudio.
Conclusiones: Este estudio representa el primer tratamiento taxonómico para el género Spigelia que incluye todas las especies de la región central y norte del continente americano. La información recopilada en este trabajo puede ser útil para ser integrada en análisis filogenéticos que ayuden a resolver las relaciones intragenéricas del grupo. Asimismo, la aplicación de herramientas de modelado de distribución potencial que permitan ubicar áreas para futuras colectas, así como el desarrollo de análisis biogeográficos que ayuden a comprender la distribución de la diversidad de Spigelia a lo largo del continente.

Sexuality and Sexual and Reproductive Health Depiction in Social Media: Content Analysis of Kinyarwanda YouTube Channels
Authors: Uhawenimana Thierry Claudien , Musabwasoni Marie Grace Sandra , Nsengiyumva Richard , Mukamana Donatilla
Published: August 2023

Background

Social media platforms such as YouTube can be used to educate people of reproductive age about healthy and nonrisky sexual and reproductive health (SRH) practices and behaviors. However, there is a paucity of evidence to ascertain the authenticity of sexuality and SRH content on Kinyarwanda YouTube, making it difficult to determine the extent to which these topics are covered, the characteristics of available videos, and the themes covered by these videos.

Objective

The aims of this study were (1) to determine the extent to which YouTube channels in Kinyarwanda-language videos address sexuality and SRH issues, identify the general characteristics of the available videos (type of video, when published, intention for the audience, and content focus), and the aspects of sexuality and SRH covered; and (2) to identify the themes covered by retrieved Kinyarwanda videos, and the extent to which the channels have been used to communicate issues of sexuality and SRH during the COVID-19 pandemic.

Methods

Using a content analysis approach, we searched Kinyarwanda YouTube channels to analyze videos about sexuality and SRH. The adopted framework for data collection from social media platforms builds on three key steps: (1) development, (2) application, and (3) assessment of search filters. To be included, an audio and/or visual video had to be in Kinyarwanda and the video had to be directed to the general public. Descriptive statistics (frequency and percentages) were computed to characterize the basic characteristics of retrieved channels, portrayal of the videos, and presentation of sexuality and SRH themes that emerged from retrieved videos. Further analysis involved cross-tabulations to explore associations between the focus of the channel and the date when the channel was opened and the focus of the channel and who was involved in the video.

Results

The YouTube search retrieved 21,506 videos that tackled sexuality and SRH topics. During the COVID-19 pandemic, there was a 4-fold increase (from 7.2% to 30.6%) in channels that solely focused on sexually explicit content. The majority of the 1369 retrieved channels (n=1150, 84.0%) tackled the topic of sexuality, with sexually explicit content predominantly found in the majority of these videos (n=1082, 79%), and only 16% (n=287) of the videos covered SRH topics.

Conclusions

This is the first study to analyze the use of YouTube in communicating about sexuality and SRH in the Kinyarwanda language. This study relied on videos that appeared online. Further research should gather information about who accesses the videos, and how channel owners and individuals involved in the videos perceive the impact of their videos on the Rwandan community’s sexuality and SRH.

Authors: Aclan Roslyn , George Stacey , Laver Kate
Published: August 2023

Background

Age-friendly environments in homes and communities play an important role in optimizing the health and well-being of society. Older people have strong preferences for remaining at home as they age. Home environment assessment tools that enable older people to assess their homes and prepare for aging in place may be beneficial.

Objective

This study aims to establish the validity of a digital self-assessment tool by assessing it against the current gold standard, an occupational therapy home assessment.

Methods

A cohort of adults aged ≥60 years living in metropolitan Adelaide, South Australia, Australia, assessed their homes using a digital self-assessment tool with 89 questions simultaneously with an occupational therapist. Adults who were living within their homes and did not have significant levels of disabilities were recruited. Cohen κ and Gwet AC1 were used to assess validity.

Results

A total of 61 participants (age: mean 71.2, SD 7.03 years) self-assessed their own homes using the digital self-assessment tool. The overall levels of agreement were high, supporting the validity of the tool in identifying potential hazards. Lower levels of agreement were found in the following domains: steps (77% agreement, Gwet AC1=0.56), toilets (56% agreement, κ=0.10), bathrooms (64% agreement, κ=0.46), and backyards (55% agreement, κ=0.24).

Conclusions

Older people were able to self-assess their homes using a digital self-assessment tool. Digital health tools enable older people to start thinking about their future housing needs. Innovative tools that can identify problems and generate solutions may improve the age-friendliness of the home environment.
Cause of Death in Patients with Oropharyngeal Carcinoma by Human Papillomavirus Status: Comparative Data Analysis (Preprint)
Authors: Zhang Dong-Dong , Lei Min , Wang Yue , Zeng Pei-Ji , Hong Yong-Jun , Cai Cheng-Fu
Published: August 2023

BACKGROUND

The incidence of oropharyngeal squamous cell carcinomas (OPSCC) has increased in recent decades, and human papillomavirus (HPV) infection is the main cause of OPSCC. The data regarding causes of death (CODs) are vitally important in informing follow-up strategies and revising treatment strategies to deal with any possible preventable treatment-related COD. However, limited studies have assessed the competing COD by HPV status in patients with OPSCC.

OBJECTIVE

We aimed to analyze the distribution of the competing COD according to HPV status in OPSCC.

METHODS

We retrospectively included stage I-IVB patients with OPSCC from the Surveillance, Epidemiology, and End Results database between 2010 and 2015. The association between HPV status and head and neck cancer–specific mortality (HNCSM), second primary cancer mortality (SPCM), and noncancer-caused mortality (NCCM) were analyzed. The chi-square test, Kaplan-Meier analysis, and Fine and Gray model were used for statistical analysis.

RESULTS

We included 5852 patients in this study and 73.2% (n=4283) of them had HPV-related tumors. A total of 1537 (26.3%) patients died, including 789 (51.3%), 333 (21.7%), and 415 (27%) patients who died from head and neck cancer, second cancer, and noncancer causes, respectively. The 5-year HNCSM, SPCM, NCCM, and overall mortality were 14.7%, 6.5%, 7.7%, and 26.4%, respectively. Those with HPV-positive disease had a lower cumulative incidence of HNCSM (subdistribution hazard ratio [sHR] 0.362, 95% CI 0.315-0.417; P<.001), SPCM (sHR 0.400, 95% CI 0.321-0.496; P<.001), and NCCM (sHR 0.460, 95% CI 0.378-0.560; P<.001) than those with HPV-negative disease. The 5-year risk of HNCSM was 26.9% and 10.7% in those with HPV-negative and HPV-positive disease, respectively (P<.001). The 5-year risk of SPCM was 12.4% and 4.6% in those with HPV-negative and HPV-positive disease, respectively (P<.001). The 5-year risk of NCCM of death was 13.7% and 5.8% in those with HPV-negative and HPV-positive disease, respectively (P<.001). Using the Fine and Gray competing-risks model, our results show that those with HPV-negative tumors had a significantly higher risk of HNCSM (P<.001), SPCM (P<.001), and NCCM (P<.001) than those with HPV-negative tumors.

CONCLUSIONS

HPV-positive OPSCC has a lower NCSM, SPCM, and NCCM as compared to those with HPV-negative OPSCC. HPV positivity is a favorable prognostic factor in the context of overcoming cancer as well as in terms of reducing the risk of other CODs in OPSCC. Our finding supports the need to tailor patient follow-up based on the HPV status of patients with OPSCC.

Authors: Ali Suad , Alizai Hira , Hagos Delal Jemal , Rubio Sindy Ramos , Calabia Dale , Serrano Jimenez Penelope , Senthil Vinuu Aarif , Appel Lora
Published: August 2023

BACKGROUND

Lifestyle behaviors including exercise, sleep, diet, stress, mental stimulation, and social interaction significantly impact the likelihood of developing dementia. Mobile health (mHealth) apps have been valuable tools in addressing these lifestyle behaviors for general health and well-being, and there is growing recognition of their potential use for brain health and dementia prevention. Effective apps must be evidence-based and safeguard user data, addressing gaps in the current state of dementia-related mHealth apps.

OBJECTIVE

This study aims to describe the scope of available apps for dementia prevention and risk factors, highlighting gaps and suggesting a path forward for future development.

METHODS

A systematic search of mobile app stores, peer-reviewed literature, dementia and Alzheimer association websites, and browser searches was conducted from October 19, 2022, to November 2, 2022. A total of 1044 mHealth apps were retrieved. After screening, 152 apps met the inclusion criteria and were coded by paired, independent reviewers using an extraction framework. The framework was adapted from the Silberg scale, other scoping reviews of mHealth apps for similar populations, and background research on modifiable dementia risk factors. Coded elements included evidence-based and expert credibility, app features, lifestyle elements of focus, and privacy and security.

RESULTS

Of the 152 apps that met the final selection criteria, 88 (57.9%) addressed modifiable lifestyle behaviors associated with reducing dementia risk. However, many of these apps (59/152, 38.8%) only addressed one lifestyle behavior, with mental stimulation being the most frequently addressed. More than half (84/152, 55.2%) scored 2 points out of 9 on the Silberg scale, with a mean score of 2.4 (SD 1.0) points. Most of the 152 apps did not disclose essential information: 120 (78.9%) did not disclose expert consultation, 125 (82.2%) did not disclose evidence-based information, 146 (96.1%) did not disclose author credentials, and 134 (88.2%) did not disclose their information sources. In addition, 105 (69.2%) apps did not disclose adherence to data privacy and security practices.

CONCLUSIONS

There is an opportunity for mHealth apps to support individuals in engaging in behaviors linked to reducing dementia risk. While there is a market for these products, there is a lack of dementia-related apps focused on multiple lifestyle behaviors. Gaps in the rigor of app development regarding evidence base, credibility, and adherence to data privacy and security standards must be addressed. Following established and validated guidelines will be necessary for dementia-related apps to be effective and advance successfully.

A Systematic Background Check of TRICARE Provider Names (Preprint)
Authors: Bychkov David
Published: August 2023

UNSTRUCTURED

During Covid-19, the Defense Health Agency's TRICARE insurance plan expanded its coverage to include 30.1% additional civilian healthcare providers. The DHA's Annual Report, however, states that TRICARE's provider directories are only 80% accurate. Although the DHA's 9.6 million beneficiaries need expanded access to care, they also require protection from misleading information, medical fraud, patient abuse, and identity theft. Since 2013, the Department of Health and Human Services' Office of the Inspector General has excluded 17,706 physicians from federal health programs due to misconduct. Patients who receive care from excluded providers experience worse medical outcomes. To determine if any excluded provider names were found on TRICARE's website, we performed background checks on TRICARE West's healthcare provider directory between January 1 and March 2023. Out of 39,463 provider names sampled from 22 states, there were 2,398 matches (6.08%) with individuals and businesses found in the OIG List of Excluded Individuals and Entities (OIG-LEIE), the GSA-SAM, the HHS HIPAA Breach Report, the International Trade Administration's Consolidated Screening List, the OIG-HHS Fugitive List, the FBI's January 6th Capitol Violence List of Charged Defendants,
State Medicaid Exclusion Lists, and FDA Debarment Lists. Our study includes demographic analysis of the matching names and recommendations for an Insider Threat Management model. We recommend that DHA officials publish the National Provider Identification (NPI) numbers of all TRICARE providers. NPI numbers facilitate more accurate background checks of healthcare providers.

Comparison of the Composition and Abundance of Phytoplankton Based on Different Land Use in the Cisadane River, Tangerang Regency
Authors: Varmlandia Alifa , Hadisusanto Suwarno
Published: August 2023

Phytoplankton is an autotrophic organism that produce its own food through the process of photosynthesis with the help of sunlight which forms the basis of water productivity to be utilized for trophic organisms above. In freshwater, river plankton are categorized as potamoplankton. Rivers are a dominant freshwater ecosystem and have a more stable morphology than other freshwaters. Changes in land function is triggered by an increase in human population, an increase in the number of residential areas and industrial activities that discharge untreated waste into the river. Because of the importance of phytoplankton for life, it is necessary to conduct research on the Comparison of Phytoplankton Composition and Abundance Based on Different Land Uses in the Cisadane River, Tangerang Regency. In this study, sampling was carried out using a purposive sampling method by measuring parameters such as pH, temperature, and water transparency. Identification of phytoplankton composition and abundance was carried out using the Sedgwick Rafter Counting Cell (SRCC) using the sweep method. The results of this study obtained 23 phytoplankton genera from 6 classes consisting of: Bacillaryophyceae, Cyanophyceae, Chlorophyceae, Conjugatophyceae, Trebouxiophyceae, and Zygnematophyceae. Phytoplankton abundance was 185-490 Ind/L with the highest abundance in both areas are Bacillaryopiceae and Navicula. The diversity index was 1.307-2.124 and the dominance index was 0.201-0.461. Water quality parameters that affect the composition and abundance of phytoplankton are water-transparency, pH, and water temperature. The fertility level of the Cisadane River waters has an oligotrophic fertility level.
Algorithmic Maps and the Political Geography of Early-modern Japan
Authors: Ravina Mark
Published: August 2023

Many of our conventional mapping practices are ill-suited to the complexities and nuances of pre-modern politics, especially in the non-Western world. Choropleth maps suggest that political borders are clear and uniform, but early modern politics was characterized by ill-defined and overlapping political spheres. This study uses interactive maps to explore the case of composite state borders in early modern Japan. Using points, rather than polygons, to represent villages, we reproduce how Tokugawa-era officials understood political space primarily as population nodes, not as clearly defined polygons. In lieu of conventional borders, we calculate Voronoi polygons to show where political authority was spatially fragmented. Using logit analysis we show that increased spatial contiguity allowed lords (daimyo) to establish monopolies and tax their holdings more intensively. Other factors, such as the lord’s rank, figure prominently in the historiography, but can not be substantiated in our analysis.
Lecture Course “Modern Physics”
Authors: V. K. Voronov , L. A. Gerashchenko , O. V. Dudareva , A. Funtikova E.
Published: August 2023

In the paper, the structure of the lecture course “Modern Physics” is described in detail. The course is based on a logical presentation of modern ideas about quantum-, atomic-, nuclear-, and molecular physics as well as astrophysics. A special attention is paid to a relatively new interdisciplinary research field, namely the physics of open systems, and to the study of clusters as one of the most promising scientific areas. Separate chapters of the textbook are devoted to nonlinear optics, quantum information, structure and dynamics of molecules. The fundamental laws and concepts of modern physics, their relationship and origin are comprehensively discussed. It is underlined that this lecture course is intended, first of all, for students of technical universities, postgraduate students of relevant specialties, as well as professors of vocation-related subjects. The inclusion of new sections of physics in the curricula of universities is rationalized, in particular, by the fact that physics is closely related to engineering. Due to this fact, the important role that physics plays in society becomes especially evident. The paper may also be of interest to those who are fond of physics and its state-of-the art.
Need for an Aligned ESP Writing Course for Engineering Students
Authors: Kharbanda Prem Raj
Published: August 2023

The English writing skills of engineering students in India is a tricky proposition. The term- end university exams majorly test their writing ability but the students focus more on oral communication skills to do well in group discussions and interviews to get placed. To add to this, the pressure of domain subjects and a lack of awareness about the real need of writing skills at the workplace and in higher education contribute both to a neglect and poor standard of writing. University courses are not updated frequently and proper needs analysis is not done. India produces the largest number of engineers annually. The paper argues for a mechanism to continuously update English writing course for engineering students by aligning the views of all stakeholders. It also recommends granting autonomy and flexibility to ESP teachers to draft a new or modify the existing writing course which will be updated as per the academic and workplace needs.
Education, Sisterhood and Solidarity in Buchi Emecheta’s Kehinde (1994)
Authors: Sene Abdou , Gueye Mansour
Published: August 2023

Facing patriarchal African societies where men were empowered at the expense of women, the main concern of African female writers of the first and second generations has chiefly been the restoration of the social condition of the African woman. The male-oriented perspectives in African male writings did not align with African women writers’. So as a response, these female writers started coming up with a new type of female characters whose stories are woven from their own experience and milieu. One of those novels is Emecheta’s Kehinde (1994) where the heroine, after living in London for eighteen years, joined her husband in Lagos, could no longer bear the brunt of life she was expected to lead as a woman and wife in a Nigerian patriarchal society. Consequently, she was compelled to return to England. One may wonder what solutions Buchi Emecheta proposes in order to help Nigerian women in particular and African women in general improve their living conditions in a male-dominated African society. From a feminist perspective, this article will deal with The Empowerment of Women in Buchi Emecheta’s Kehinde. Based on sociology, culture, psychology and feminism, this study will first analyze the importance of women’s education and then will examine Emecheta’s advocacy for solidarity among women.

Humanitarian work has proven to be dangerous over the years, causing, over time, emotional or physical trauma in many professionals who deal with natural disasters that have affected large nations. These professionals need to be able to deal flexibly and adapt quickly to the reality of the current context, running the risk of developing symptoms of depression, PTSD - Post Traumatic Stress Disorder and compassion fatigue, a syndrome of biological, psychological and emotional exhaustion. social aspects, a very important indicator, studied in health professionals, considered the greatest threat to the mental health of professionals, especially those ones who work directly with trauma and victims. Health professionals, in direct contact with people who are suffering, at risk of death, or in a situation of pain, can lead them to a secondary model of prolonged stress, called Compassion Fatigue, which can be labeled as “ Cost of caring”, or “Emotional pain”. In view of this, the present work aims to present an investigation on mental health indicators in health professionals who work in humanitarian actions. A cross-sectional, descriptive exploratory research was carried out using the chain reference sampling technique or the snowball technique. The study was conducted online through the Google Forms survey management application. The results show that these professionals receive more support from the family than leadership, colleagues and friends, and the younger the professional's age, the higher the compassion fatigue index.
Censorship and autocensorship: Some considerations on the editorial history of the Parhaego
Authors: Benedittis Andrea De
Published: August 2023

In this article, we have examined some aspects of the editing of the Parhaego (Reflections on Parhae). First of all, we have tried to contextualize the work within the panorama of late Chosŏn historiography. In this sense, we have remarked that the work is part of a gradual reshaping of the story of Parhae, rearticulated within the narrative of Chosŏn history. Yu Tŭkkong’s major contribution was not to revolutionize the historical narrative of Korea nor the perception of the Parhae kingdom, but rather to collect all the sources then available for reconstructing the history of the kingdom, enjoying his privileged position within the Kyujanggak (the Royal Library). In considering this, we have observed that despite the apparent liberalism of the Chŏngjo reign, publishing and scholarship were actually under strict surveillance. During this period, the king imposed a ban on the import of books from the Qing Empire and also forced several scholars to correct their literary style. Amid this climate of control and censorship, the editing of the Parhaego took place－a work that had a rather unusual and troubled genesis, being subjected to numerous alterations and corrections since its publication in 1784. Reconstructing the genesis of this book, albeit only partially, may also provide a starting point for further reflections on authorship during this crucial phase of the Chosŏn period, when the book was exposed to possible corrections, rewritings, and expansions, even without the full consent of the original author. This process is particularly evident in the Parhaego, which was not merely historical work, but also highly political as a manifesto giving voice to the policy of reconquering the Northern Territories that was in vogue in those years.
EXTRATO DE ORA-PRO-NOBIS COMO INIBIDOR DE CORROSÃO
Authors: Dessupoio Fernandes Larissa , Pressentin Cardoso Sheila
Published: August 2023

A corrosão é um processo espontâneo que ocorre sobre superfícies metálicas, acarretando prejuízos para diversos setores industriais. Os inibidores de corrosão são composições que atuam na proteção de peças metálicas e no retardamento do processo corrosivo, sendo os inibidores de adsorção os mais indicados para o meio ácido. A maioria dos inibidores existentes no mercado são tóxicos aos seres humanos e ao meio ambiente, por isso extratos naturais de origem vegetal passaram a ser testados como inibidores de corrosão ambientalmente seguros. A pesquisa apresentada teve por objetivo avaliar o uso de extratos aquoso e liofilizado da ora-pro-nobis como potencial matéria-prima para a formulação de inibidores de corrosão naturais para o aço carbono P110 em ácido clorídrico 1 mol.L-1. A eficiência de inibição dos extratos foram calculadas a partir de ensaios gravimétricos, variando a concentração dos extratos, e de isotermas de adsorção. O extrato aquoso da ora-pro-nobis obteve a maior eficiência de inibição com o uso de uma concentração de 30% v/v, no valor de 87,87%, com o extrato liofilizado tendo a maior eficiência de inibição na concentração de 1 g/L, no valor de 87,55%. A eficiência de inibição do extrato liofilizado aumenta com o tempo do ensaio. Ambos os extratos apresentam potencial para uso como inibidor de corrosão, tendo como base as condições usadas nos ensaios. Dentre as isotermas de adsorção testadas, a isoterma de Frunkin apresentou o maior coeficiente de determinação (R2), com a energia livre de adsorção sendo de -20,54 kJ.mol-1, indicando que o processo de adsorção do extrato da ora-pro-nobis sobre a superfície metálica é espontâneo e de natureza física.

Published: August 2023

Background and Objectives For T1–T2 early glottic cancer, single modality treatment with radiation therapy (RT) or transoral laser microsurgery is the standard therapeutic option. However, the choice between surgery and RT has been debated for decades. Even though patient selection bias for each modality inherently exists in the retrospective study, this study aimed to compare the oncologic outcomes of the actual treatment of these patients between surgery-based treatment and RT.Materials and Method The medical records of 417 patients with T1–T2N0 glottic squamous cell carcinoma were reviewed who were treated at our institution between 1995 and 2014. The patients were divided into two groups; primarily surgery-based treatment (OP, n=209) or RT (n=208).Results In the T1 stage, local failure, overall survival (OS), and disease-free survival (DFS) rates were not different between the OP and RT groups. However, in the T2 stage, the local failure rate was higher in the RT group (p<0.01). OS and DFS were higher in the OP group (p=0.019 and p=0.004, respectively). Larynx-preservation rate was similar in both groups (97.1% and 96.2%, p=0.576). Multivariate analysis showed that age (>65), presence of multiple primary cancer, and treatment modality were significant variables influencing OS and DFS.Conclusion Surgery-based treatment provided better local control rates, DFS, and OS in patients with T1–T2N0 glottic SCC. In the T1 stage, treatment outcomes were similar between OP and RT groups. In the T2 stage, OP showed better results than RT, suggesting that refined strategies are required to improve the oncologic outcomes of RT for T2 glottic cancer.

Background and Objectives This study aimed to evaluate the voice of patients with vocal cord palsy using the Praat compared to Speech tool.Materials and Method The medical record of the patients with vocal cord palsy from 2013 to 2021 was analyzed retrospectively to validate Praat as a voice evaluation modality compared to the speech tool. Total 60 patients were enrolled in this study. Thirty control and 30 vocal cord palsy patients were selected to undergo recording of voice samples. The voice samples, /a/ and “Sancheck” were evaluated both groups and cepstral peak prominence was analyzed with both modalities; Praat and speech tool.Results Statistically significant differences were observed between the control and vocal cord palsy groups in the speech tool and Praat. There was also a significant difference between pre- and post-treatment values in the vocal cord palsy group. A similar change in the voice value was observed using both methods. The Praat showed a lower value in 1st visit of patients with vocal cord palsy in the vowel test. The Praat vowel test may sensitively represent voice problems in patients with vocal cord palsy. This could contribute to decision-making regarding the treatment modality for vocal cord palsy.Conclusion Praat is open-access software that is freely available. It can be easily and sufficiently used for voice evaluation in patients with vocal cord palsy.
Two Cases of Laryngomalacia With Congenital Vallecular Cyst Treated by Supraglottoplasty
Authors: Kim HeeJung , Choi Nayeon
Published: August 2023

Vallecular cyst consisted of a unilocular cystic mass of variable size arising from the lingual surface of the epiglottis and containing clear fluid is a rare occurrence in children. Although a cyst is benign, it may cause serious airway obstruction and even death if not treated appropriately. Also, laryngomalacia is the most common congenital anomaly that causes inspiratory stridor and airway obstruction in the newborn. Symptoms typically begin to appear at around 2 to 3 weeks of age and become worse between 4 and 8 months. With a review of literature, we report two cases of vallecular cyst with symptomatic laryngomalacia in a 1-month-old female and a 2-month-old male. Both patients experienced symptom relief after undergoing endoscopic supraglottoplasty.
A non-invasive and simple method of rescuing an entrapped tongue from a glass water bottle for a small state hospital: a case report
Authors: Oral Hayrunnisa , Mert Lezgin , Köktürk Bora
Published: August 2023

If children try to vigorously drink fluid from a glass bottle or play with it, their tongues can be entrapped in the bottle wherein the vacuum is created. The entrapped tongue causes lingual edema, leading to the lingual necrosis and upper airway obstruction. In this case, a 5-year-old boy whose tongue was entrapped in a glass bottle visited the emergency department of a small state hospital, where his tongue was removed non-invasively by applying positive pressure into the bottle.

A rare case of splenic hematoma after drainage of splenic abscess with infective endocarditis
Authors: Li Xuejie , Huang Kun , Yang Jiaqi
Published: August 2023

Infective endocarditis with splenic abscesses remains a complex and
unusual clinical scenario. We present a rare case of splenic hematoma
caused by puncture and drainage of splenic abscess with infective
endocarditis. The puncture drainage of the splenic abscess may lead to
bleeding or the spread of infection. So when infective endocarditis is
complicated with splenic abscess, splenectomy rather than drainage of
the splenic abscess is preferred to lower the risk of splenic hemorrhage
and eradicate the source of infection.
