    Abstract Purpose: To compare which imaging and biochemical biomarkers are associated with different stages of diabetic retinopathy (DR) in type 2 diabetes mellitus patients with diabetic macular edema (DME).
    Patients and methods: It was a cross-sectional, observational study that included 100 patients of DME with different stages of DR. Patients were divided into two groups: Group A - DME with non-proliferative diabetic retinopathy (NPDR) and Group B - DME with proliferative diabetic retinopathy (PDR). Group A was further subdivided into three subgroups: A (1) - DME with mild NPDR, A (2) - DME with moderate NPDR, and A (3) - DME with severe NPDR. The primary outcome measure was the association of imaging and biochemical biomarkers with different stages of DR in patients with DME.
    Results: Out of 100 patients, Group A (1) had 1, Group A (2) 44, Group A (3) 29, and group: B had 29 patients. As Group A (1) had only one patient, we did not include it in the calculation. The overall mean age of the study population was 54.84+9.87 years, with a male preponderance (76%). The HbA1c levels, serum triglyceride level, serum cholesterol level, and microalbuminuria level showed no significant association with different stages of DR (P>0.05). Still, we found high serum urea levels (p=0.027) in Group B patients. The optical coherence tomography (OCT)-based imaging biomarkers - central subfield thickness (CST), cystoid macular edema (CME), subretinal fluid (SRF), and hyperreflective foci (HRF) - showed no significant association with various stages of DR. The presence of diffuse retinal thickness (DRT) (p=0.04) and the epiretinal membrane (ERM) (p=0.04) showed significant association with Group B patients.
    Conclusion: The essential biochemical biomarkers such as serum urea levels and DRT and ERM may be considered an important imaging biomarker for the advanced stage of DR.

    Abstract Metabolic acidosis affects about 15% of patients with chronic kidney disease. As kidney function declines, the kidneys progressively fail to eliminate acid, primarily reflected by a decrease in ammonium and titratable acid excretion. Several studies have shown that the net acid load remains unchanged in patients with reduced kidney function; the ensuing acid accumulation can precede overt metabolic acidosis, and thus, indicators of urinary acid or potential base excretion, such as ammonium and citrate, may serve as early signals of impending metabolic acidosis. Acid retention, with or without overt metabolic acidosis, initiates compensatory responses that can promote tubulointerstitial fibrosis via intrarenal complement activation and upregulation of endothelin-1, angiotensin II, and aldosterone pathways. The net effect is a cycle between acid accumulation and kidney injury. Results from small- to medium-sized interventional trials suggest that interrupting this cycle through base administration can prevent further kidney injury. While these findings inform current clinical practice guidelines, large-scale clinical trials are still necessary to prove that base therapy can limit chronic kidney disease progression or associated adverse events.

    Abstract Medical data processing is exponentially increasing day by day due to the frequent demand for many applications. Healthcare data is one such field, which is dynamically growing day by day. In today's scenario, an enormous amount of sensing devices and data collection units have been employed to generate and collect medical data all over the world. These healthcare devices will result in big real-time data streams. Hence, healthcare-based big data analytics and monitoring have gained hawk-eye importance but needs improvisation. Recently, machine and deep learning algorithms have gained importance to analyze huge amounts of medical data, extract the information, and even predict the future insights of diseases and also cope with the huge volume of data. But applying the learning models to handle big/medical data streams remains to be a challenge among the researchers. This paper proposes the novel deep learning electronic record search engine algorithm (ERSEA) along with firefly optimized long short-term memory (LSTM) model for better data analytics and monitoring. The experimentations have been carried out using Apache Spark using the different medical respiratory data. Finally, the proposed framework results are contrasted with existing models. It shows the accuracy, sensitivity, and specificity like 94%, 93.5%, and 94% for less than 5 GB dataset, and also, more than 5 GB it provides 94%, 92%, and 93% to prove the extraordinary performance of the proposed framework.

    Abstract Aim: To report cumulative mortality rates using survival analysis from an outbreak of 211 patients with post COVID-19 rhino-orbito-cerebral mucormycosis (ROCM) in central India.
    Methods: Case files of eligible patients were evaluated and mucor was identified from deep nasal swabs using freshly prepared KOH mount. All patients underwent contrast enhanced MRI and disease staging was done based on the extent of anatomical involvement. All patients received intravenous Amphotericin B and sinus debridement was done when possible. Orbital exenteration was reserved for patients with advanced orbital disease.
    Results: The mean age was 50.7 ± 10.2 of which 147 (70%) were men. At presentation, ROCM was limited to sinuses in 72 (34%), orbital extension was seen in 102 (48%) and 31 (15%) had CNS extension. Sinus debridement was possible in 82% cases (n = 173). Thirty-five (16.6%) patients died due to ROCM. The mean follow-up of patients who survived was 126.6 ± 16.4 days. The cumulative mortality rate at day 10 was 4.8% (95%CI = 2.6-8.8%) and increased 13.1% (95%CI = 9.1-18.7%) at day 30 and to 18.4% (95%CI = 13.6-24.8%) at day 60. Majority of deaths (n = 26, 75%) occurred within 1-month of ROCM presentation. Multivariable hazards analysis showed that patients with CNS involvement had a 6.5 times higher risk of death (Hazard Ratio = 6.71, 95% CI = 2.9-15.5, p < 0.001).
    Conclusion: We report significantly lower mortality rates compared to recent literature that varies from 30 to 80% at 1-month follow-up. Timely sinus debridement and systemic Amphotericin B can help reduce mortality. Presence of CNS extension significantly increased the mortality risk with patients with ROCM.

    Abstract The comorbidity of keratoconus with Fuchs' endothelial dystrophy with cataract is a rare clinical combination. We present an amalgamation of surgical techniques to manage the above clinical conditions and its complications in single setting. The modified triple procedure, namely, the phacoemulsification, pinhole pupilloplasty, and pre-Descemet's endothelial keratoplasty (PDEK) in the order of description is followed in single sitting. Lens removal by phacoemulsification, correction of irregular astigmatism by pinhole pupilloplasty (pinhole optics), and exchanging the endothelial layer for PDEK forms the main segments of the triple procedure. This combination of techniques may decrease the risk of multiple surgeries and its related complications. Moreover, it will allow the patient for faster visual rehabilitation by improving the uncorrected visual acuity and visual quality.

    Abstract Objective: The present study was investigated to provide a documentary evidence for the determination of rutin, isoquercetin, and quercetin flavonoids from the flora of
    Materials and methods: RP-HPLC analysis was performed by gradient elution with a low-pressure gradient using 0.5% acetic acid: acetonitrile as a mobile phase with a flow rate of 1.0 ml/min. The separation was done at 26°C using a Kinetex XB-C18 column as stationary phase and the detection wavelength at 356 nm. The proposed method was validated as per International Conference on Harmonisation guidelines with respect to specificity, linearity, precision, accuracy, limit of detection (LOD), and limit of quantification (LOQ).
    Results: The validated results were within the acceptable limits. In specificity, the retention time of rutin, isoquercetin, and quercetin peak in the sample was matched with the reference standard peak and showed good resolution. An excellent linearity was obtained with correlation coefficient (r) higher than 0.999. In precision, the repeatability and intermediate showed <1.0% of % relative standard deviation of peak area percentage indicating high precision and accurate. The recovery rate for rutin, isoquercetin, and quercetin was between 99.85%-101.37%, 101.90%-103.24%, and 101.74%-106.73%, respectively. The lower LOD and LOQ of rutin, isoquercetin, and quercetin enable the detection and quantitation of these flavonoids in
    Conclusion: The developed analytical method is convenient for the determination of flavonoids content in herbal drugs.

    Abstract The SARS-CoV-2 subvariant BA.2.86 'Pirola', first identified in Denmark in August 2023, has manifested with a significantly mutated spike protein profile, suggesting a heightened ability to evade vaccine-induced and infection-induced antibodies. This article outlines the epidemiological spread, immune response implications, and global responses to BA.2.86. Preliminary observations indicate community transmissions of the subvariant, even among those previously infected or vaccinated. Notably, the BA.2.86 infection has shown a potential to amplify antibody responses. The variant's emergence has evoked memories of the Omicron variant's rise in late 2021, though global immunity levels might modulate the impact of BA.2.86 impact differently. Continuous genomic surveillance, coupled with integrated diagnostic and epidemiological strategies, proves crucial in early detection and management. The emergence of BA.2.86 reaffirms the unpredictable nature of the COVID-19 pandemic, emphasizing the need for ongoing research, adaptability, and global collaboration.
