Impact of Implementing Paris System on Diagnostic Precision and Management of Urinary Bladder Neoplasms.

The diagnosis of atypia has always been under question both by the pathologist and the clinician. It was one of the main aims of the Paris system (TPS) to reduce the number of cases under the AUC (Atypical urothelial cells) category. With the strict criteria laid down by the Paris system, the rate of diagnosis of this category has reduced markedly. This study was done to test the impact of implementing TPS categories and criteria in comparison to our previously used system. TPS is one of the important deciding factors for the management of the patient. The management of patients with AUC diagnosis often varies depending on the treating physician (urologist/nonurologist). For further categorization of the diagnosis of AUC, markers like p53 and Ki67 can be used. One hundred urinary cytology specimens received for the period of 6 months were included in the study. The presentation of the categorical variables was done in the form of numbers and percentages (%). Interrater kappa agreement was used to find out the strength of the agreement between the Paris system and the traditional system. Using histopathological diagnosis as the gold standard, sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic accuracy were calculated. Immunohistochemistry was performed on the cell block for Ki67 and p53, and their values were correlated with histopathological examination, using Spearman's rank correlation. The interrater kappa agreement analyzed between the traditional reporting system and the Paris system was 0.522. Around 32% (6/19) of cases that were reported as AUC by the traditional system were recategorized under negative for high-grade urothelial carcinoma (NHGUC) by the Paris system. Thus, obliviating the need for further management and decreasing the unnecessary cost of the health care system with a decrease in patient anxiety. Histopathology was available in 28 cases and diagnostic accuracy of urine cytology classified by TPS was 89.2% with a sensitivity of 94.4%, specificity of 80%, positive likelihood ratio of 89.4, and negative likelihood ratio of 88.6. The correlation coefficient of p53 with grading of carcinoma was found to be strong at 0.864. The correlation coefficient of Ki67 with grading of carcinoma was also as strong as 0.885. TPS along with immunohistochemistry improves the performance of urine cytology by reclassifying the AUC category into other groups and increases the sensitivity for detecting HGUC.

Exploring Sociodemographic Factors in Allergic Fungal Rhinosinusitis in a Northern California Patient Population.

BACKGROUND: Allergic fungal rhinosinusitis (AFRS) is a subtype of chronic rhinosinusitis (CRS) that has previously been associated with younger age and Black patients. However, the role of demographic and socioeconomic factors in AFRS severity remains to be fully elucidated. OBJECTIVE: The objective of this study was to determine whether demographic and socioeconomic factors are associated with incidence of AFRS, as well as with disease severity in Northern California. METHODS: A retrospective cohort study was conducted of adult patients with AFRS and CRS from 2010 to 2019. AFRS was determined by the Bent and Kuhn criteria, and severity was assessed by radiographic evidence of cranioorbital invasion and other clinical parameters. Chi-square and t-test were used to assess demographic and socioeconomic differences between AFRS and CRS cohorts, and multivariable logistic regression was used to assess risk factors for severe AFRS. RESULTS: Black patients represented 26.2% (55/210 patients) of the AFRS group and 4.9% (842/17,300 patients) of the CRS group, with pairwise comparison of race/ethnicity categories showing that the AFRS group had significantly higher proportions of Black race/ethnicity compared with other race/ethnicities (p < 0.01). AFRS and CRS groups differed significantly by age, with mean ages of 48.7 and 51.0 years, respectively (p = 0.04). There were no significant differences in gender, Medicaid status, comorbidities, and socioeconomic status measures. Multivariate logistic regression showed that Black patients had higher odds of having severe AFRS (adjusted odds ratio = 2.29; 95% confidence interval: 1.18-4.45). CONCLUSION: AFRS has a unique predilection for Black patients, and severe disease is also more likely in this population.

Preclinical models of atherosclerosis: An overview.

Atherosclerosis is a primary cause of illness and death globally and its mechanism is still unclear. Different animal models have been created to evaluate the progression of atherosclerosis, allowing researchers to carefully control the circumstances of the experiment as well as the nutrition and environmental risk factors. To investigate the negative effects of various interventions, pathophysiological alterations might be generated utilizing genetic or pharmacological methods. These models' molecular and pathophysiological mechanisms have been clarified through experiments, and they have served as platforms for the creation of new drugs. Different models can be employed to address various research problems, each with its own benefits and drawbacks. In the current review study, various species of atherosclerosis models are discussed, along with the viability of using them in experiments.

Chemical kinetics and thermodynamics of PPO activity, colour changes and microbial degradation during blanching of the sugarcane billets.

BACKGROUND: Sugarcane juice, which has a short shelf life, is a popular thirst-quenching and rejuvenating beverage worldwide. The limited shelf life is a result of changes in polyphenol oxidase (PPO) activity, total plate count (TPC) and color attributes (L*, a* and b*-values). We hypothesized that chemical kinetics and thermodynamics of blanched sugarcane cane juice causing alterations in PPO, TPC, and L, a* and b*-values will address the challenges of sugarcane juice preservation. RESULTS: Sugarcane billets were blanched at variable time-temperature combinations in the range 0-20 min and 70-90 °C. Reaction rates increased with increasing temperature; PPO activity, TPC and colour followed first-order kinetics. PPO activity had an activation energy (Ea) of 81 kJ mol-1. The half life (t½) dropped from 16.5 to 3.47 min and decimal reduction time (D-values) dropped from 54.83 to 11.52 min. Thus reactions were temperature-sensitive. Thermodynamic studies indicated an endothermic (positive enthalpy values, ΔH > 0; 78.10 kJ mol-1) and reversible process (negative entropy values ΔS < 0; -0.044 kJmol-1 K-1). Michaeli-Menten constant (Km) and maximum velocity (Vmax) of PPO activity were determined by adding variable lemon juice concentrations in sugarcane juice. As the Km values increased (from 5.53 to 15.81 mm) and Vmax values decreased (from 666.67 to 384.61 UmL-1), a Lineweaver-Burk plot suggested decreased PPO affinity of sugarcane juice. CONCLUSION: The results of the present study indicate that studies on chemical kinetics and thermodynamics (PPO, TPC and L, a* and b*-values) of blanched sugarcane cane juice shall mitigate challenges of sugarcane juice preservation. © 2024 Society of Chemical Industry.

SEMA3B inhibits TGFß-induced extracellular matrix protein production and its reduced levels are associated with a decline in lung function in IPF.

Idiopathic pulmonary fibrosis (IPF) is marked by the activation of fibroblasts, leading to excessive production and deposition of extracellular matrix (ECM) within the lung parenchyma. Despite the pivotal role of ECM overexpression in IPF, potential negative regulators of ECM production in fibroblasts have yet to be identified. Semaphorin class 3B (SEMA3B), a secreted protein highly expressed in lung tissues, has established roles in axonal guidance and tumor suppression. However, the role of SEMA3B in ECM production by fibroblasts in the pathogenesis of IPF remains unexplored. Here, we show the downregulation of SEMA3B and its cognate binding receptor, neuropilin 1 (NRP1) in IPF lungs compared with healthy controls. Notably, the reduced expression of SEMA3B and NRP1 is associated with a decline in lung function in IPF. The downregulation of SEMA3B and NRP1 transcripts was validated in the lung tissues of patients with IPF, and two alternative mouse models of pulmonary fibrosis. In addition, we show that TGFß functions as a negative regulator of SEMA3B and NRP1 expression in lung fibroblasts. Furthermore, we demonstrate the anti-fibrotic effects of SEMA3B against TGFß-induced ECM production in IPF lung fibroblasts. Overall, our findings uncovered a novel role of SEMA3B in the pathogenesis of pulmonary fibrosis and provided novel insights into modulating the SEMA3B-NRP1 axis to attenuate pulmonary fibrosis.

Reproductive functions and pregnancy outcome in female patients with celiac disease.

BACKGROUND AND AIM: Abnormalities in the reproductive functions are often ignored while evaluating a patient with celiac disease (CeD). We evaluated the entire reproductive functions in female patients with CeD. METHODS: In a case control study between 2020 and 2021 using detailed questionnaire, we evaluated reproductive functions (age at menarche, menstrual pattern, fertility, pregnancy outcome and menopause) in biopsy-proven female patients with CeD of age >10 years. The questionnaire was administered either in person or telephonically. Age-matched healthy female controls (twice the number) were also recruited. RESULTS: Of 1086 CeD patients, 470 were females and 288 were included. As compared with controls (n = 586), females with CeD had higher age at menarche (14.6 ± 2.0 vs 13.6 ± 1.5 years; P = 0.001), delayed menarche (30.8% vs 11.4%; P = 0.001), abnormal menstrual pattern (39.7% vs 25.8%; P < 0.001), involuntary delay in conception at > 1 year (33.8% vs 11.8%; P = 0.01), current infertility rate (10.5% vs 5.2%;P = 0.028), and poorer overall pregnancy outcomes (abortion [23.5% vs 12.8%; P = 0.001], pre-term birth [16.3% vs 3.7%; P = 0.001]). CONCLUSIONS: Either one or more aspect of reproductive functions and pregnancy outcome is affected adversely in three-fourth female patients with CeD.

Associations between nonnutritive sucking habits, developing malocclusion, and various feeding practices in 3-6-year-old Indian urban children: A case-control study.

BACKGROUND: Nutritive sucking and nonnutritive sucking (NNS) may affect the craniofacial development, differently. AIM AND OBJECTIVES: We investigated associations between NNS habits (NNSHs), developing malocclusion, and various feeding practices in 3-6-year-old children. METHODOLOGY: A sample of 350 children 3-6-year-old from various preschools were selected for this case-control study (94 with NNSH and 256 without NNSH). NNSH (outcome) and feeding practices and developing malocclusions (exposures) were assessed using a structured study tool. RESULTS: The prevalence of NNSH in 3-6-year-old children was 26.8%. The odds (95% [confidence interval (CI)]) of boys compared to girls having NNSH were 0.66 (0.4121-1.706) (P = 0.0290). The overall prevalence of developing malocclusion in 3-6-year-old children was 34.01% out of which open bite was most commonly reported with 12.57% followed by spacing 8.5%, increased overjet 6.8%, crowding 2.2%, posterior crossbite and rotation 1.4%, and overbite 1.14%. Breastfeeding was found to be the most commonly used mode of feeding reported by 53.42% of mothers. It was found that the odds (95% [CI]) of subjects having NNSH were 0.66 (0.4694-0.9460) (P < 0.0001) who were not breastfed as compared to those who were breastfed. Among developing malocclusions, increased overjet with P = 0.0019, open bite with P = 0.0416, and spacing with P = 0.0243 were found to be associated with feeding practices. CONCLUSION: The prevalence of NNSH and developing malocclusions (increased overjet, open bite, and spacing) was 26.8% and 34.01%, respectively. Breastfeeding played a protective role against developing NNSH.

Contemporary experience of mitral transcatheter edge-to-edge repair technology in patients with mitral annular calcification.

BACKGROUND: Mitral annular calcification (MAC) has been an exclusion for many of the earlier pivotal trials that were instrumental in gaining device approval and indications for mitral transcatheter edge-to-edge repair (M-TEER). AIMS: To evaluate the impact of MAC on the procedural durability and success of newer generation MitraClip® systems (G3 and G4 systems). METHODS: Data were collected from Northwell TEER registry. Patients that underwent M-TEER with third or fourth generation MitraClip device were included. Patients were divided into -MAC (none-mild) and +MAC (moderate-severe) groups. Procedural success was defined as ≤ grade 2 + mitral regurgitation (MR) postprocedure, and durability was defined as ≤ grade 2 + MR retention at 1 month and 1 year. Univariate analysis compared outcomes between groups. RESULTS: Of 260 M-TEER patients, 160 were -MAC and 100 were +MAC. Procedural success was comparable; however, there were three patients who required conversion to cardiac surgery during the index hospitalization in the +MAC group versus none in the -MAC group (though this was not statistically significant). At 1-month follow-up, there were no significant differences in MR severity. At 1-year follow-up, +MAC had higher moderate-severe MR (22.1% vs. 7.5%; p = 0.002) and higher mean transmitral gradients (5.3 vs. 4.0 mmHg; p = 0.001) with no differences in mortality, New York Heart Association functional class or ejection fraction. CONCLUSION: In selective patients with high burden of MAC, contemporary M-TEER is safe, and procedural success is similar to patients with none-mild MAC. However, a loss of procedural durability was seen in +MAC group at 1-year follow-up. Further studies with longer follow-ups are required to assess newer mTEER devices and their potential clinical implications in patients with a high burden of MAC.

Synchronous Papillary and Follicular Carcinoma with Scalp and Nodal Metastasis: A case report with review of literature.

Collision tumor comprise of existence of two histologically distinct and separate neoplasms in any organ. Thyroid gland is an uncommon site for these tumors, with frequently involved organs being liver, adrenal and stomach. Even among the synchronous tumors of thyroid, papillary and medullary carcinoma are most commonly reported. The present case reports a rare presentation of a collision tumor comprising of papillary and follicular carcinoma with scalp metastasis from the follicular carcinoma and lymph nodal metastasis from the papillary component. It is essential for the clinician to be aware of such an entity so as to guide further treatment and management.

Kayser-Fleischer rings: The pathognomonic for Wilson's disease.

Wilson's disease is a genetic disorder of copper metabolism that primarily manifests with hepatic and neurological features. Kayser-Fleischer rings (KF rings) are pathognomonic of Wilson's disease and helps in establishing its diagnosis.

A novel class of inhibitors that disrupts the stability of integrin heterodimers identified by CRISPR-tiling-instructed genetic screens.

The plasma membrane is enriched for receptors and signaling proteins that are accessible from the extracellular space for pharmacological intervention. Here we conducted a series of CRISPR screens using human cell surface proteome and integrin family libraries in multiple cancer models. Our results identified ITGAV (integrin αV) and its heterodimer partner ITGB5 (integrin ß5) as the essential integrin α/ß pair for cancer cell expansion. High-density CRISPR gene tiling further pinpointed the integral pocket within the ß-propeller domain of ITGAV for integrin αVß5 dimerization. Combined with in silico compound docking, we developed a CRISPR-Tiling-Instructed Computer-Aided (CRISPR-TICA) pipeline for drug discovery and identified Cpd_AV2 as a lead inhibitor targeting the ß-propeller central pocket of ITGAV. Cpd_AV2 treatment led to rapid uncoupling of integrin αVß5 and cellular apoptosis, providing a unique class of therapeutic action that eliminates the integrin signaling via heterodimer dissociation. We also foresee the CRISPR-TICA approach to be an accessible method for future drug discovery studies.

Therapeutic targeting Tudor domains in leukemia via CRISPR-Scan Assisted Drug Discovery.

Epigenetic dysregulation has been reported in multiple cancers including leukemias. Nonetheless, the roles of the epigenetic reader Tudor domains in leukemia progression and therapy remain unexplored. Here, we conducted a Tudor domain-focused CRISPR screen and identified SGF29, a component of SAGA/ATAC acetyltransferase complexes, as a crucial factor for H3K9 acetylation, ribosomal gene expression, and leukemogenesis. To facilitate drug development, we integrated the CRISPR tiling scan with compound docking and molecular dynamics simulation, presenting a generally applicable strategy called CRISPR-Scan Assisted Drug Discovery (CRISPR-SADD). Using this approach, we identified a lead inhibitor that selectively targets SGF29's Tudor domain and demonstrates efficacy against leukemia. Furthermore, we propose that the structural genetics approach used in our study can be widely applied to diverse fields for de novo drug discovery.

Unveiling the potential of linseed mucilage, its health benefits, and applications in food packaging.

Industrial waste products derived from the oil industry often contain valuable substances and elements with great potential. These by-products can be used for various purposes, including as nutrients, bioactive compounds, fuels, and polymers. Linseed mucilage (LM) is one such example of a beneficial by-product obtained from linseed. It possesses favorable chemical and functional properties, depending on its method of extraction. Different pretreatments, such as enzymatic extraction, microwave-assisted extraction, pulse electric field, and ultrasound-assisted extraction, have been explored by various researchers to enhance both the yield and quality of mucilage. Furthermore, LM has exhibited therapeutic effects in the treatment of obesity, diabetes, constipation, hyperlipidemia, cancer, and other lifestyle diseases. Additionally, it demonstrates favorable functional characteristics that make it suitable to be used in bioplastic production. These properties preserve food quality, prolong shelf life, and confer antimicrobial activity. It also has the potential to be used as a packaging material, especially considering the increasing demand for sustainable and biodegradable alternatives to plastics because of their detrimental impact on environmental health. This review primarily focuses on different extraction techniques used for linseed mucilage, its mechanism of action in terms of health benefits, and potential applications in food packaging.

Neurological Manifestations of Scrub Typhus Infection in Pediatric Patient: A Case Report From Tertiary Care Hospital in Central India.

Scrub typhus is a neglected tropical bacterial disease endemic in central India which can manifest as meningitis/meningoencephalitis in children. It is difficult to diagnose clinically, especially in the absence of eschar or rash. Scrub typhus is seldom considered the differential diagnosis of meningitis in the Indian subcontinent. Appropriate investigations can lead to early detection of infection and initiation of correct antibiotic treatment leading to better patient prognosis even when features of meningitis supervene. Here, we report a pediatric case of scrub typhus meningitis that could be saved due to timely investigations and initiation of appropriate antimicrobial agents.

Growth, ultrastructural and physiological characteristics of Abelmoschus cytotypes under elevated ozone stress: a study on ploidy-specific responses.

Tropospheric ozone (O3 ) is a significant abiotic stressor whose rising concentration negatively influences plant growth. Studies related to the differential response of Abelmoschus cytotypes to elevated O3 treatment are scarce and need further exploration to recognise the role of polyploidisation in stress tolerance. In this study, we analysed the changes in growth pattern, ultrastructure, physiology and foliar protein profile occurring under O3 stress in Abelmoschus moschatus (monoploid), Abelmoschus esculentus (diploid) and Abelmoschus caillei (triploid). Our findings showed that higher stomatal conductance in A. moschatus triggered higher O3 intake, causing damage to stomatal cells and photosynthetic pigments. Additionally, it caused a reduction in photosynthetic rates, leading to reduced plant growth, total biomass and economic yield. This O3 -induced toxicity was less in diploid and triploid cytotypes of Abelmoschus . Protein profiling by sodium dodecyl sulpate-polyacrylamide gel electrophoresis showed a significant decrease in the commonly found RuBisCO larger and smaller subunits. The decrease was more prominent in monoploid compared to diploid and triploid. This study provides crucial data for research that aim to enhance plant ability to withstand O3 induced oxidative stress. Our findings may help in developing a tolerant variety through plant breeding techniques, which will be economically more advantageous in reaching the objective of sustainable production at the high O3 levels projected under a climate change scenario.

Viridibacillus culture derived silver nanoparticles exert potent anticancer action in 2D and 3D models of lung cancer via mitochondrial depolarization-mediated apoptosis.

Lung cancer is one of the most commonly occurring cancer types that accounts for almost 2 million cases per year. Its resistance to anticancer drugs, failure of new molecules in clinical trials, severe side-effects of current treatments, and its recurrence limit the success of anticancer therapies. Nanotherapeutic agents offer several advantages over conventional anticancer therapies, including improved retention in tumors, specificity, and anticancer effects at lower concentrations, hence reducing the side-effects. Here, we have explored the anticancer activity of silver nanoparticles synthesized in Viridibacillus sp. enriched culture medium for the first time. Such green nanoparticles, synthesized by biological systems, are superior to chemically synthesized ones in terms of their environmental footprint and production cost, and have one crucial advantage of excellent stability owing to their biological corona. To assess anticancer activity of these nanoparticles, we used conventional 2D cultured A549 cells as well as 3D spheroids of A549 cells. In both models of lung cancer, our silver nanoparticles diminished cell proliferation, arrested DNA synthesis, and showed a dose dependent cytotoxic effect. The nanoparticles damaged the DNA and mitochondrial structures in both A549 cells and A549 spheroids, leading to mitochondrial depolarization and increased cell permeability. Low lethal median doses (LD50) for 2D cultured A549 cells (1 µg/ml) and for A549 spheroids (13 µg/ml) suggest that our nanoparticles are potent anticancer agents. We also developed in vitro tumor progression model and in vitro tumor size model using 3D spheroids to test anticancer potential of our nanoparticles which otherwise would require longer experimental duration along with large number of animals and trained personnel. In these models, our nanoparticles showed strong dose dependent anticancer activity. In case of in vitro tumor progression model, the A549 cells failed to form tight spheroidal mass and showed increased dead cell fraction since day 1 as compared to control. On the other hand, in case of in vitro tumor size model, the 4 and 8 µg/ml nanoparticle treatment led to reduction in spheroid size from 615 ± 53 µm to 440 ± 45 µm and 612 ± 44 µm to 368 ± 62 µm respectively, within the time span of 3 days post treatment. We believe that use of such novel experimental models offers excellent and fast alternative to in vivo studies, and to the best of our knowledge, this is the first report that gives proof-of-concept for use of such novel in vitro cancer models to test anticancer agents such as Viridibacilli culture derived silver nanoparticles. Based on our results, we propose that these nanoparticles offer an interesting alternative for anticancer therapies, especially if they can be combined with classical anticancer drugs.

Alzheimer Disease or Other Dementias in Adult Day Services Centers, 2020.

Objectives-Alzheimer disease or other dementias are among the most common chronic conditions of adult day services center (ADSC) participants. This report compares prevalence of these conditions (referred to collectively as dementia) among participants in ADSCs that provide specialized care for dementia with other ADSCs, by census region, metropolitan statistical area status, chain affiliation, and ownership type. Methods-This report uses data from the ADSC component of the 2020 National Post-acute and Long-term Care Study. The survey collects data on ADSCs every 2 years from all 50 states and the District of Columbia. Data were collected from January 2020 through mid-July 2021. The results are based on survey responses from about 1,800 eligible ADSCs from a census of 5,500 ADSCs and are weighted to be nationally representative. The percentage of participants diagnosed with dementia is calculated from responses to a question about the number of current participants diagnosed with dementia. Geographical and ADSC characteristics include census region, metropolitan statistical area, ownership status, and chain affiliation. Results-In ADSCs that provide specialized dementia care, 42.2% of participants had dementia, while 22.7% of participants also had dementia in ADSCs that do not specialize in dementia care. The overall prevalence of dementia was similar across regions, with a slightly lower percentage in the West. Dementia was more prevalent in ADSCs in metropolitan statistical areas, nonchain centers, and nonprofit centers. In general, for each of the selected characteristics, the prevalence of dementia was higher in specialized centers than in nonspecialized centers.

Digital Rectal Exams Are Infrequently Performed Prior to Anorectal Manometry.

BACKGROUND: Digital rectal examination should be performed prior to anorectal manometry; however, real-world data is lacking. AIMS: Characterize real world rates of digital rectal and their sensitivity for detecting dyssynergia compared to anorectal manometry and balloon expulsion test. METHODS: A retrospective single-center study was conducted to examine all patients who underwent anorectal manometry for chronic constipation between 2021 and 2022 at one tertiary center with motility expertise. Primary outcomes consisted of the rate of digital rectal exam prior to anorectal manometry; and secondary outcomes included the sensitivity of digital rectal exam for dyssynergic defecation. RESULTS: Only 42.3% of 142 patients had digital rectal examinations prior to anorectal manometry. Overall sensitivity for detecting dyssynergic defecation was 46.4%, but significantly higher for gastroenterology providers (p = .004), and highest for gastroenterology attendings (82.6%). CONCLUSIONS: Digital rectal examination is infrequently performed when indicated for chronic constipation. Sensitivity for detecting dyssynergic defecation may be impacted by discipline and level of training.

Role of encapsulation on the bioavailability of omega-3 fatty acids.

Omega-3 fatty acids (omega-3 FAs) have been widely recognized for their therapeutic advantages, including anti-inflammatory and cardioprotective properties. They have shown promise in enhancing regulatory function, promotingdevelopment and mitigating the progression of diabetes and cancer. The scientific communities, along with industries, are actively endorsing initiatives aimed at increasing the daily intake of lipids rich in omega-3 FAs. Nevertheless, incorporating polyunsaturated FAs (PUFAs) into food products poses several challenges due to their susceptibility to oxidation when exposed to oxygen, high temperatures, and moisture. This oxidative deterioration results in undesirable flavours and a loss of nutritional value. Various methods, including physical blending, interesterification, and encapsulation, have been utilized as ways to enhance the stability of edible oils rich in PUFA against oxidation. Encapsulation has emerged as a proven strategy for enhancing the oxidative stability and functional properties of omega-3 FA-rich oils. Multiple encapsulation methods have been developed to stabilize and improve the delivery of omega-3 FAs in food products. The selection of an appropriate encapsulation method depends on the desired application of the encapsulated oil. In addition, encapsulation enhances the bioavailability of omega-3 FAs by promoting increased absorption of the encapsulated form in the intestinal epithelium. This review discusses the techniques and principles of omega-3 FA-rich oil encapsulation and its role in improving stability and bioavailability. Furthermore, it also investigates the potential health benefits of these encapsulated oils. This review explores the variations in bioavailability based on encapsulation techniques and processing, offering vital insights for nutrition and product development.

Applications of artificial intelligence and bioinformatics methodologies in the analysis of ocular biofluid markers: a scoping review.

PURPOSE: This scoping review summarizes the applications of artificial intelligence (AI) and bioinformatics methodologies in analysis of ocular biofluid markers. The secondary objective was to explore supervised and unsupervised AI techniques and their predictive accuracies. We also evaluate the integration of bioinformatics with AI tools. METHODS: This scoping review was conducted across five electronic databases including EMBASE, Medline, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science from inception to July 14, 2021. Studies pertaining to biofluid marker analysis using AI or bioinformatics were included. RESULTS: A total of 10,262 articles were retrieved from all databases and 177 studies met the inclusion criteria. The most commonly studied ocular diseases were diabetic eye diseases, with 50 papers (28%), while glaucoma was explored in 25 studies (14%), age-related macular degeneration in 20 (11%), dry eye disease in 10 (6%), and uveitis in 9 (5%). Supervised learning was used in 91 papers (51%), unsupervised AI in 83 (46%), and bioinformatics in 85 (48%). Ninety-eight papers (55%) used more than one class of AI (e.g. > 1 of supervised, unsupervised, bioinformatics, or statistical techniques), while 79 (45%) used only one. Supervised learning techniques were often used to predict disease status or prognosis, and demonstrated strong accuracy. Unsupervised AI algorithms were used to bolster the accuracy of other algorithms, identify molecularly distinct subgroups, or cluster cases into distinct subgroups that are useful for prediction of the disease course. Finally, bioinformatic tools were used to translate complex biomarker profiles or findings into interpretable data. CONCLUSION: AI analysis of biofluid markers displayed diagnostic accuracy, provided insight into mechanisms of molecular etiologies, and had the ability to provide individualized targeted therapeutic treatment for patients. Given the progression of AI towards use in both research and the clinic, ophthalmologists should be broadly aware of the commonly used algorithms and their applications. Future research may be aimed at validating algorithms and integrating them in clinical practice.
