A Giant Mass Filling the Left Atrium: A Case Report
Authors: Gonçalves Fernando Fonseca , Borges Sara , Moreira José Ilídio
Published: November 2021

Background:

Cardiac tumors have heterogeneous and unspecific clinical presentations
which is why their diagnosis is difficult.

Case report:

A middle-aged woman presented to the emergency department with unspecific symptoms
developing over 2 weeks. Multimodality imaging revealed a large mass filling the left atrium
with a large base adherent to the fossa ovalis and flow obstruction. After surgical extraction, the
anatomopathological analysis was compatible with a primary benign cardiac tumor.

Conclusion:

Clinical presentation of cardiac tumors is usually unspecific and multimodality imaging
is crucial in the diagnostic workflow. Surgical excision should be performed as quickly as possible.
Changes in the Area Adjacent to the Internal Receiver-Stimulator of Cochlear Implant: A Retrospective Study
Authors: Aljazeeri Isra , Khurayzi Tawfiq , Abdelsamad Yassin , Almuhawas Fida , Hagr Abdulrahman
Published: November 2021

Background:

In some patients with cochlear implants, bony resorption at the internal receiver-stimulator site can be observed on postoperative computed tomography. Therefore, it is essential to elucidate the effects of the internal receiver-stimulator on the scalp and bony bed over time.

Objective:

We aimed to evaluate how the internal receiver-stimulator of a cochlear implant device changed the thickness of the surrounding scalp and skull over time using computed tomography.

Methods:

This retrospective study evaluated patients who underwent cochlear implantation and received two computed tomography scans postoperatively for different indications at a tertiary referral centre. The main outcomes were scalp thickness and bony bed depth.

Results:

Fourteen ears were included in this study. There was very good inter-rater reliability, with a Cronbach’s alpha of 0.94. The mean scalp thickness over the internal receiver-stimulator was 6.02 (+/-2.4) mm in the first scan and decreased with no significant change to 5.62 mm (+/-1.64) in the second scan (p = 0.59, paired t-test). The mean depth of the bony bed increased significantly from 1.39 mm (+/-0.93) to 2.62 mm (+/-1.24) (p = 0.03).

Conclusion :

There was no change in the thickness of the scalp overlying the internal receiver-stimulator indicating that the scalp was more resistant than the bony skull to the tensile pressure exerted by the internal receiver-stimulator. In contrast, the bony bed depth of the internal receiver-stimulator increased over time. This can result in decreased internal receiver-stimulator protrusion and decreased risk of device displacement and migration.
Effect of Functionality of Organophosphorus Flame Retardants on
Flammability and Thermal Stability of DGEBA-Based Epoxy Resin Nanocomposites
Authors: Bazzad Priyanka , Dahiya J.B.
Published: November 2021

Background:

Epoxy resins have been extensively used in fire hazard environments,
such as printed circuit boards, electrical isolation materials, adhesives, construction, and transportation
due to their economically viable, simple processing. Therefore, the development of thermally
stable and flame-retardant epoxy resin systems is essential.

Objective:

The aim of the present study was to study the effect of the functionality of organophosphorus
flame retardants on DGEBA-based epoxy resin nanocomposites on thermal stability and
flame retardancy.

Method:

DGEBA (diglycidyl ether of bisphenol-A)-based epoxy resin nanocomposites having 2.0
wt% phosphorus were prepared with organophosphorus flame retardants with different functionalities
by using an in-situ polymerization method. The flame retardant compounds uni-functional 9,
10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and bi-functional 2-(6-oxid-6Hdibenz
[c, e] [1, 2] oxaphosphorin 6-yl) 1, 4-benzenediol (DOPO-HQ) were prepared. The thermal
behavior of composites was studied by TG and DTA techniques. The flammability behavior was investigated
by UL-94 and limiting oxygen index (LOI) tests.

Results:

The XRD and TEM results showed the mixed dispersion of nanoclay platelets in an epoxy
matrix. The thermal stability of the epoxy composite (EPDOPO-HQ) containing bi-functional DOPOHQ
is increased by 16°C in comparison to the epoxy composite (EPDOPO) containing uni-functional
DOPO. According to the TG analysis, the addition of nanoclay was observed to be more effective
and synergistic with bi-functional DOPO-HQ as the EPDOPO-HQ/NC sample gains more resistance to
degradation after around 450°C and also gave rise to a high char yield. Epoxy resin samples containing
reactive flame retardants gave UL-94 V-0 rating, but further addition of 2.0 wt% nanoclay
lowered the rating from V-0 to V-1.

Conclusions:

TG analysis of the epoxy composite samples showed that the addition of nanoclay
were observed to be synergistic with bi-functional flame retardant (DOPO-HQ) as the EPDOPO-HQ/NC
sample gained more resistance to degradation after around 450°C due to the formation of mixed intercalated
and exfoliated structure. The EPDOPO-HQ sample gave a high char yield with increased
onset degradation temperature, high thermal stability as well as high flame retardancy.

Authors: Ryan Kelly A , Smith Shawna N , Yocum Anastasia K , Carley Isabel , Liebrecht Celeste , Navis Bethany , Vest Erica , Bertram Holli , McInnis Melvin G , Kilbourne Amy M
Published: November 2021

Background

Life Goals is an evidence-based self-management intervention that assists individuals with bipolar disorder (BD) by aligning BD symptom coping strategies with their personal goals. The intervention can be availed via in-person and telephonic sessions, and it has been recently developed as an individualized, customizable mobile app.

Objective

We examined the feasibility, usability, and acceptability of the Life Goals self-management app among individuals diagnosed with BD who used the app for up to 6 months.

Methods

A total of 28 individuals with BD used the Life Goals app on their personal smartphone for 6 months. They completed key clinical outcome measurements of functioning, disability, and psychiatric symptoms at baseline, 3 months, and 6 months, in addition to a poststudy survey about usability and satisfaction.

Results

Participants used the app for a median of 25 times (IQR 13-65.75), and for a longer time during the first 3 months of the study. The modules on depression and anxiety were the most frequently used, accounting for 35% and 22% of total usage, respectively. Overall, the study participants found the app useful (15/25, 60%) and easy to use (18/25, 72%), and they reported that the screen displayed the material adequately (22/25, 88%). However, less than half of the participants found the app helpful in managing their health (10/25, 40%) or in making progress on their wellness goals (9/25, 36%). Clinical outcomes showed a trend for improvements in mental and physical health and mania-related well-being.

Conclusions

The Life Goals app showed feasibility of use among individuals with BD. Higher user engagement was observed in the initial 3 months with users interested more frequently in the mood modules than other wellness modules. Participants reported acceptability with the ease of app use and satisfaction with the app user interface, but the app showed low success in encouraging self-management within this small sample. The Life Goals app is a mobile health technology that can provide individuals with serious mental illness with more flexible access to evidence-based treatments.
Cannabis as a medicine from the social media perspective: Narrative review of the literature (Preprint)
Authors: Khademi Habibabadi Sedigheh , Hallinan Christine Mary , Conway Mike , Bonomo Yvonne Ann
Published: November 2021

BACKGROUND

Online user generated data is increasingly used for monitoring public health concerns and behaviors, and provides data that is not readily accessible using traditional health reporting systems.

OBJECTIVE

The objective of this papers is to provide a narrative review of the outcomes of studies which have utilised user-generated text as a data source to study cannabis as a medicine.

METHODS

Medline, Scopus, Web of Science, and Embase databases were searched from inception until May 2021. The inclusion criteria for this review were primary research studies and reviews that reported on the analysis of online user-generated content related to cannabis as medicine.

RESULTS

Thirty-eight studies were included in this review. The search was performed during May 2021 and was limited to English-language studies published between January 1974 and May 2021. Thirty-two studies analysed text, three focused on the analysis of online video content, and three analysed web search volume trends. The studies showed that many consumers utilise online sources to find information about, and make decisions on the use of cannabis as medicine. Sentiment around medicinal use of cannabis was found to be mostly positive with minimal mentions of adverse events associated with product use.

CONCLUSIONS

Online user-generated text is widely used by both consumers and researchers for studying cannabis and its medicinal effects. Consumers value their ability to exchange experiences online and come to rely on online information sources. Researchers can investigate consumer sentiment and experiences, including the opportunity to monitor cannabis effects and adverse events. However, the nature of the online environment means that information is often incomplete and not supported by scientific evidence, and affords a challenge to health governance agencies to provide factual, timely, and reliable evidence-based health information to consumers.
Telehealth Availability and Use of Related Technologies Among Medicare-Enrolled Cancer Survivors: Cross-sectional Findings From the Onset of the COVID-19 Pandemic (Preprint)
Authors: Lama Yuki , Davidoff Amy J , Vanderpool Robin C , Jensen Roxanne E
Published: November 2021

BACKGROUND

There has been rapid integration of telehealth into care delivery during the COVID-19 pandemic. However, little is known about technology ownership, internet access and use for communication, and telehealth availability among cancer survivors, particularly those enrolled in Medicare.

OBJECTIVE

This study aims to identify sociodemographic associations with technology ownership, internet access and use for communication, and telehealth availability in a population-based sample of Medicare-enrolled cancer survivors.

METHODS

Data are from the Medicare Current Beneficiary Survey COVID-19 Summer 2020 Supplement administered between June 10 and July 15, 2020. Analyses were restricted to beneficiaries who reported a prior (nonskin) cancer diagnosis and a usual source of care (N=2044). Dichotomous outcomes included technology ownership, internet access, internet use for communication, and telehealth availability from providers. Sociodemographic correlates included sex, age, race/ethnicity, Medicare/Medicaid dual enrollment, rurality, census region, and self-reported comorbidities.

RESULTS

Over half (957/2044, 53%) of cancer survivors reported using the internet for communication purposes, and 62% (1218/2044) reported that their usual provider had telehealth services available. Using the internet for communication purposes was reported less frequently for rural compared to urban survivors (adjusted probability of 28% vs 46%; P<.001) and for Hispanic and Black survivors compared to non-Hispanic White survivors (29%, 31%, and 44%, respectively; all P<.01). Rural survivors reported lower telehealth availability (53% vs 63%; P<.001); no significant differences in telehealth availability were identified by race/ethnicity.

CONCLUSIONS

During the COVID-19 pandemic, study findings highlight a complex digital divide among Medicare beneficiaries with a history of cancer related to device ownership necessary for telehealth, internet access and use for communication, and reports of providers having telehealth available. Multilevel approaches are needed to increase equitable telehealth availability and use for cancer survivors. Suggested strategies include increasing broadband internet access to providers and patients in at-risk communities, supporting telehealth implementation among providers that serve populations with known health disparities, raising awareness of providers’ available telehealth services among patients, and screening for technology use and provision of telehealth-related technical assistance among older and historically underserved cancer survivors.
Acceptability of Web-Based Mental Health Interventions in the Workplace: Systematic Review (Preprint)
Authors: Scheutzow Johanna , Attoe Chris , Harwood Joshua
Published: November 2021

BACKGROUND

Web-based interventions have proven to be effective not only in clinical populations but also in the occupational setting. Recent studies conducted in the work environment have focused on the effectiveness of these interventions. However, the role of employees’ acceptability of web-based interventions and programs has not yet enjoyed a similar level of attention.

OBJECTIVE

The objective of this systematic review was to conduct the first comprehensive study on employees’ level of acceptability of web-based mental health interventions based on direct and indirect measures, outline the utility of different types of web-based interventions for work-related mental health issues, and build a research base in the field.

METHODS

The search was conducted between October 2018 and July 2019 and allowed for any study design. The studies used either qualitative or quantitative data sources. The web-based interventions were generally aimed at supporting employees with their mental health issues. The study characteristics were outlined in a table as well as graded based on their quality using a traffic light schema. The level of acceptability was individually rated using commonly applied methods, including percentile quartiles ranging from low to very high.

RESULTS

A total of 1303 studies were identified through multiple database searches and additional resources, from which 28 (2%) were rated as eligible for the synthesis. The results of employees’ acceptability levels were mixed, and the studies were very heterogeneous in design, intervention characteristics, and population. Approximately 79% (22/28) of the studies outlined acceptability measures from high to very high, and 54% (15/28) of the studies reported acceptability levels from low to moderate (overlap when studies reported both quantitative and qualitative results). Qualitative studies also provided insights into barriers and preferences, including simple and tailored application tools as well as the preference for nonstigmatized language. However, there were multiple flaws in the methodology of the studies, such as the blinding of participants and personnel.

CONCLUSIONS

The results outline the need for further research with more homogeneous acceptability studies to draw a final conclusion. However, the underlying results show that there is a tendency toward general acceptability of web-based interventions in the workplace, with findings of general applicability to the use of web-based mental health interventions.

ABSTRACT

 

Background: When pain, deformity and instability compromise wrist function, wrist stabilization by means of fusion is a procedure of recognized validity. The goal of wrist arthrodesis is to provide the patient with a stable wrist for power grip and the predictable relief of pain while sacrificing wrist motion. The radioscapholunate (RSL) fusion is one of salvage procedure indicated in the case of traumatic or degenerative osteoarthritis of the radiocarpal joint, involving the lunate facet of the radius. RSL-fusion reduced total wrist motion (3 MC/Rad) in the F/E axis to an average of 49% of F/E in the unfused wrist but  preserves midcarpal joint motion while alleviating pain.

Case Report: We report a 43-year-old male patient with pain on his left wrist. 10 months before admission, he felt down from stairs with his left hand bear his body weight. He broke his wrist and got surgery at that time. Because still feel pain and his index finger can’t fully extensed, he brought to Soeharso orthopaedic hospital. Here, we have done RSL-fusion using cross pinning K-Wire to reduce pain, distal scapoid excision to optimizing radial angulation and release superficial flexor tendon index finger of left hand.

Discussion: With Secondary OA of left wrist post traumatic with neglected radiocarpal dislocation and superficial flexor tendon contracture due to entrapment index finger of left hand post RSL-fusion, distal scapoid excision and release contracture can reduce pain at radiocarpal joint and improve range of movement.

Conclusion: The goal of Radioscapholunate (RSL) fusion is to optimizing wrist motion and strength while minimizing or eliminating pain

Hotspot is one form of utilizing Wireless LAN technology that can be used to access internet services and is usually found in public areas such as libraries, campus internet parks, or offices. Aspects that need to be considered in hotspots to make users feel comfortable is security then at the provider side, the aspect that needs to be considered is the regulation of bandwidth allocation to optimize the data transfer speeds that the network and to prevent the possibility of dense network traffic. RADIUS server is one type of server that can be used at hotspots to secure hotspots because it supports various types of encryption. In this study, optimization of the settings for hotspot network bandwidth is optimized by integrating the RADIUS server with RouterOS. Bandwidth allocation management is done by determining the active time of a user account and set quotas hotspot uploads and downloads for the account. The results obtained from this study indicate that when a hotspot user account has passed the active time or has passed the upload quota and the download given, the account will be deleted from the list of hotspot user accounts or disabled.
