ABSTRACT

Objectives. Knitted protective garments with reliable thermal and functional properties are the subject of intense research. However, achieving both attributes is quite challenging and necessary at the same time, especially when the fabrics are employed for undergarments. Hence, this research aims to develop fire protection clothing liners and undergarment fabrics integrating thermal comfort, fire resistance, antibacterial and antistatic properties. Methods. Knitted textiles have been engineered using two different protective yarns with different blend ratios of cotton and Protex fibers. Two variable plating threads of multifilament and channeled polyester (Sorbtek) were also employed to escort thermal comfort with protective action. Specialty treatments of the fabrics were performed imparting antimicrobial and antistatic properties. Results. Thermal characterization revealed a noticeable change in fluid transmission and heat retention characteristics with knitting and plating yarn variation. Better fluid transfer and considerable heat retention were observed in Sorbtek plated protective fabrics. However, the flame endurance was improved by reducing the cotton percentage in the primary knitting protective yarns during vertical flame retardancy characterization. Moreover, one-way analysis of variance showed that the treatment component was statistically significant (p < 0.05) in the variation of thermal characteristics.

ABSTRACT

We evaluated the efficacy of hyperbaric oxygen (HBO₂) therapy used to salvage sudden sensorineural hearing loss (SSNHL) at a short distance from ineffective primary treatment. We examined the data on 70 patients who suffered from SSNHL. The treatment was administered from 1 to 3 months after the onset of the hearing loss, i.e., after ineffective primary corticosteroid therapy. The monitored group was divided into three subgroups according to the degree of hearing impairment. Treatment success was assessed by using pre- and post-treatment audiograms. A statistically significant improvement in auditory threshold in all three frequency bands was observed in patients with severe hearing impairment of more than 60 dB, with mean auditory gains of 14.5 dB in low frequencies, 11.2 dB in middle (spoken speech) frequencies, and 13.2 dB in high frequencies. In this subgroup, 54.17 % of patients with severe hearing impairment experienced an improvement in hearing gain by 5 dB or more, 33.33 % by > 10 dB, and 25.00 % by > 20 dB. In patients with moderate and slight hearing impairments, the tendency to improve the hearing gain was not statistically significant. Based on our findings, we conclude that salvage HBO₂ treatment in patients with SSNHL is apparently most efficacious for individuals with severe hearing impairment. This finding is valuable for effective resource management in healthcare and public health.

ABSTRACT

A common complication of hyperbaric oxygen (HBO₂) treatment is middle ear barotrauma (MEB), which can lead to pain, treatment abandonment, or delay in treatment. Studies have shown that pseudoephedrine decreases MEB for pressure changes in SCUBA divers and airplane travelers. We conducted a randomized, double-blind, placebo-controlled trial to determine if pseudoephedrine effectively decreases MEB rates in patients receiving their first HBO₂ treatment. There was no statistically significant difference between the pseudoephedrine and placebo groups concerning ear pain ratings, tympanic membrane injury, or rescue medication to help equalize ear pressure. Pseudoephedrine prophylaxis, given between 45 minutes and two hours before multiplace HBO₂ treatment, does not mitigate MEB or treatment delays.

ABSTRACT

OBJECTIVE: Scoliosis is primarily seen during adolescence and often causes significant concern among patients and their families when the deformity becomes noticeable. With technological advancements, patients frequently search the Internet for information regarding their disease’s diagnosis, treatment, prognosis, and potential complications. This study aims to assess the quality of Google and ChatGPT responses to questions about scoliosis.

METHODS: A search was conducted using Google with the keyword “scoliosis.” The first ten questions listed under the “People Also Ask” (FAQs) section were recorded. Responses to these questions from ChatGPT and Google were evaluated using a four-level rating system: “Excellent response not requiring clarification,” “satisfactory requiring minimal clarification,” “satisfactory requiring moderate clarification,” and “unsatisfactory requiring substantial clarification.” Additionally, the sources of the responses were categorized as academic, commercial, medical practice, governmental, or social media.

RESULTS: ChatGPT provided “excellent responses requiring no explanation” for 9 out of 10 questions (90%). In contrast, none of Google’s responses were categorized as excellent; 50% were unsatisfactory, requiring substantial clarification; 40% were satisfactory, requiring moderate clarification, and 10% were satisfactory, requiring minimal clarification. ChatGPT sourced 60% of its responses from academic resources and 40% from medical practice websites. Conversely, Google did not use scholarly sources, with 50% of reactions derived from commercial websites, 30% from medical practice sources, and 20% from social media. When the agreement between the 4 raters, regardless of AI, was examined using Fleiss Multirater Kappa in the reliability analysis, a statistically significant (p < 0.001) moderate agreement (κ = 0.48) was found.

CONCLUSION: ChatGPT outperformed Google by providing more accurate, well-referenced responses and utilizing more credible academic sources. This suggests its potential as a more reliable tool for obtaining health-related information.

ABSTRACT

There has been varying data on whether stoma-site specimen extraction (SSE) increases the risk of ostomy-related complications versus specimen extraction via a separate incision (non-SSE). Complications may be grouped into early (skin excoriation, stoma retraction or necrosis) and late (hernia, prolapse, stenosis, and ischemia dermatitis) complications. SSE in robotic surgery requires one fewer incision, but its impact on rates of early and late stoma-related complications is unknown. We hypothesized that outcomes are similar between SSE and non-SSE robotic colorectal surgery. A retrospective single-center analysis of patients undergoing robotic colorectal surgery was performed. Adult patients (≥ 18 years) who underwent elective, minimally invasive robotic-assisted colorectal resection with either ileostomy or colostomy creation between January 1, 2017 and December 31, 2021 were included. A multivariable logistic regression was performed to compare the two groups. A total of 95 patients were identified; 68 had stoma-site extraction (SSE) performed. There were no statistically significant differences in early or late complications between the two groups. In multivariable logistic regression analysis, the extraction site was not significantly associated with the risk of post-operative stoma complications within the first year-only age demonstrated a significant association with the risk of stoma complications. SSE was associated with significantly decreased operative time, although this difference may also be due to differences between surgeons. Most patients underwent ostomy reversal within 1 year of ostomy creation. Stoma-site specimen extraction (SSE) is a safe method of specimen removal in patients undergoing robotic colorectal surgery. Increased use of SSE may allow for shorter operative times and allows for colectomies to be performed with one fewer incision. As most patients had a stoma for less than 1 year, we caution against generalizing these results to those expected to have a permanent stoma.

ABSTRACT

BACKGROUND: Since October 2019, Lebanon has been facing a severe and multifaceted economic crisis, considered one of the three most severe crises globally since the mid-1980s. Generally, economic crises and recessions are known to impact psychological well-being and mental health significantly.

AIM: Considering this unique social context, the objective of this cross-sectional study was to investigate the association between financial well-being, anxiety, and depression among Lebanese adults during times of crisis.

METHOD: This study included 225 Lebanese adults who completed an online questionnaire assessing sociodemographic data, financial well-being, anxiety, and depression.

RESULTS: Statistical analysis showed strong correlations between financial well-being and anxiety, as well as depression. This study shows an association between increasing levels of financial well-being and decreasing levels of anxiety and depression among Lebanese adults in times of crisis. Moreover, the study found negative correlations between age and anxiety, as well as age and depression. It also found that education level correlated with anxiety.

CONCLUSION: The study offers insights into mental health in Lebanese society during times of crisis and recession, especially among relatively younger adults.

ABSTRACT

INTRODUCTION: Various nephrolithometry scoring systems have been introduced to assess the outcomes of percutaneous nephrolithotomy (PCNL) and postoperative complications. Previous studies have incorporated various variables to determine factors influencing postoperative acute kidney injury (AKI). Using separate scoring systems or nomograms to predict postoperative outcomes and AKI is cumbersome. Our study aims to find if stone scoring systems can be used to predict AKI following a PCNL procedure.

MATERIALS AND METHODS: A prospective observational study was conducted at Kasturba Hospital and Medical College from December 2023 to June 2024. All patients undergoing PCNL were included in the study. Scores were calculated for all patients pre-operatively using various nephrolithometry scoring systems. Patients were divided into two groups based on the presence or absence of AKI following PCNL. The various stone scoring systems were assessed for their ability to predict AKI following PCNL.

RESULTS: Out of the 90 patients in the study, 15 (16.66%) developed AKI, and 75 (83.33%) had no AKI following PCNL. Statistical significance was found in stone size (p < 0.001), stone location (p = 0.011), Staghorn (p < 0.001), Guy’s Score (p = 0.001), STONE score (0.002), CROES Score (p = 0.001), Amplatz size (p = 0.012) and energy source (p = 0.01). No statistical significance was found when comparing sex, comorbidities, number of stones, the severity of HN, puncture location and number, intraoperative hypotension, operative time, and duration of hospital stay.

CONCLUSION: Nephrolithometry scoring systems, in addition to assessing postoperative outcomes such as stone-free rate and complications, can also be used to predict the occurrence of AKI. The use of a limited number of scoring systems to assess all the postoperative outcomes will help simplify and facilitate their use in routine clinical practice.

ABSTRACT

OBJECTIVE: To compare the quality of orthodontic clinical photographs taken with a mirrorless camera and a smartphone compared with those taken with a digital single lens reflex (DSLR) camera.

METHODS: This cross-sectional study involved six participants (models), each of whom had five extra-oral and five intra-oral photographs taken using a DSLR (Canon 70D), a mirrorless camera (Canon RP) and a smartphone (iPhone 14 Pro), resulting in a total of 180 photographs. Four orthodontists served as assessors, evaluating the quality of each photograph based on image clarity, colour accuracy and lighting. They categorised the photographs as ‘good’ (no errors), ‘acceptable’ (some errors) or ‘unacceptable’, while also noting any specific errors observed. Statistical analysis was conducted using Fisher’s exact test and Pearson’s chi-square test. All statistical tests were interpreted at a significance level of 5%.

RESULTS: Compared to the DSLR camera, the photographs taken with the mirrorless camera were of identical quality, with 100% of photographs rated as good for each camera. For the smartphone camera, 41.7% were assessed as good and 58.3% as acceptable, which was significantly less (P < 0.001) than for the DSLR (100% good). For smartphone intra-oral photographs, the majority of ‘upper occlusal’ and ‘lower occlusal’ photographs were classified as ‘good’ (62.5%), while the remaining 37.5% were rated as ‘acceptable’. In contrast, for ‘right buccal’ and ‘left buccal’ photographs, the majority of photographs (87.5%) were categorised as ‘acceptable’, with only 12.5% rated as ‘good’.

CONCLUSION: In conclusion, although DSLR and mirrorless cameras consistently produce high-quality orthodontic photographs suitable for all clinical and professional purposes, smartphone cameras fall short in photographic quality. Given their lower resolution and pixel count, smartphone-captured photographs may be adequate for clinical records but are not recommended for large-format applications.

ABSTRACT

The Recruitment and Retention for Alzheimer’s Disease Diversity in the Alzheimer’s Disease Sequencing Project (READD-ADSP) aims to recruit 5000 African participants (Alzheimer’s disease [AD] and cognitively unimpaired controls) to generate genomic and biomarker data to better characterize AD neurobiology in Africa from countries that constitute the African Dementia Consortium (AfDC). Blood samples from study participants are separated into fractions and transported to the African Coordinating Centre (ACC: Ibadan, Nigeria), where DNA extraction and long-term biospecimen storage are carried out. Plasma and DNA aliquots are shipped to the John P. Hussman Institute for Human Genomics, University of Miami (HIHG-UM, Miami, USA) for genotyping, whole genome sequencing, and biomarker analysis. Innovative solutions were devised to mitigate challenges encountered so far. Our biobanking experience in a low-resource setting demonstrates the feasibility of establishing a successful African biobanking network, as an important infrastructure to support Alzheimer’s disease and related dementias research in Africa. HIGHLIGHTS: Biobanking is gaining grounds in Africa in studies related to neurological disorders. The Recruitment and Retention for Alzheimer’s Disease Diversity in the Alzheimer’s Disease Sequencing Project (READD-ADSP) biobanking network is a new initiative to enhance infrastructure for Alzheimer’s disease and related dementias (ADRD) research in Africa through the African Dementia Consortium. The processes of the stepwise creation and development of the READD-ADSP biobanking network have been guided by global best practices and regulatory standards. Challenges were encountered in the process of establishing the READD-ADSP biobank, and home-grown solutions were developed to mitigate the challenges. The READD-ADSP biobanking experience offers lessons to researchers in low-resource settings on how collaborative efforts between the global north and global south enhance cutting-edge team science to tackle ageing-associated brain disorders in low- and middle-income countries.

ABSTRACT

BACKGROUND Salivary gland neoplasms present a diagnostic challenge due to their heterogeneous nature and varying histological subtypes. Recent studies have highlighted the potential role of inflammatory biomarkers, such as neutrophil to lymphocyte ratio (NLR) and systemic immune inflammation index (SII), in enhancing diagnostic accuracy for distinguishing between benign and malignant parotid gland tumors. This study aimed to evaluate the use of inflammatory biomarkers – NLR, platelet-to-lymphocyte ratio (PLR), SII, and systemic inflammation response index (SIRI) – in the differential diagnosis of parotid gland tumors. MATERIAL AND METHODS Patients who underwent parotidectomy in a single center between 2019 and 2023 were included. Inflammatory biomarkers (NLR, PLR, SII, SIRI) were calculated and compared according to histopathological features (benign vs malignant) and subgroups (benign: pleomorphic adenoma, Warthin, and others; and malignant: high grade, low grade, and lymphoma. RESULTS A total of 206 patients were included in the study (benign: 177, malignant: 29). No significant difference was detected in NLR, PLR, SII and SIRI values between benign and malignant tumor groups. While all inflammatory markers were found to be elevated, only PLR exhibited a statistically significant difference among high-grade, low-grade, and benign tumor groups (P=0.05). Patients with Warthin tumor revealed significantly lower PLR and higher SIRI values than those with pleomorphic adenoma (P=0.02 and P<0.001, respectively). CONCLUSIONS Evaluation of inflammatory biomarkers seems to play a promising role in diagnosing parotid tumors, especially Warthin tumor and high-grade malignancies. Due to their accessibility and cost-effectiveness, further studies are warranted to determine their accuracy and optimal use in clinical practice.
