    Abstract α-Lipoic acid (LA), a dietary supplement known for its strong antioxidant and anti-inflammatory potential, faces challenges due to its poor aqueous solubility and thermal instability. To address these issues, herein methyl-beta-cyclodextrin (M-β-CD) was utilized to create inclusion complex (IC) of LA in 1:1 M stoichiometric ratio of M-β-CD to LA. The LA-M-β-CD-IC was further combined with pullulan (PUL), a non-toxic and water-soluble biopolymer, for the development of electrospun nanofibers (NF) by green and sustainable approach. The resulting PUL/LA/M-β-CD NF formed as a self-standing and flexible material with an average diameter of 569 ± 129 nm and encapsulation efficiency of ∼86.90 %. The developed NF demonstrated an accelerated release, quick dissolution, and disintegration when exposed to artificial saliva replicating the conditions of oral cavity. PUL/LA/M-β-CD NF attenuated the production of ROS and NO by downregulating pro-inflammatory enzymes (iNOS and COX-2) in lipopolysaccharide (LPS) stimulated RAW 264.7 cells. Moreover, PUL/LA/M-β-CD NF also significantly downregulated the expression of pro-inflammatory cytokines including TNF-α, IL-6, and IL-1β along with suppression of NF-ĸB nuclear translocation in comparison to LA (at 250 μM). In nutshell, PUL/LA/M-β-CD NF demonstrated great potential as a rapid disintegrating delivery system for oral anti-inflammatory treatment due to the enhanced physicochemical characteristics of LA.

    Abstract Hemodialysis remains the most popular modality of renal replacement therapy for end-stage renal disease patients with chronic kidney disease. Various factors such as a radial artery, cephalic vein diameter, age, hypertension, and diabetes mellitus can affect the fistula maturation. This study was carried out to know the patency rates and factors affecting fistula maturation in the Indian population. This is a prospective observational study which aimed to study the patency rate of arteriovenous (AV) fistulas. On the day of surgery, patients were shifted inside the operation theater. Under all aseptic precautions, an AV fistula was formed using the radial artery and cephalic vein. All patients were followed up for 6 months. The data were analyzed using IBM SPSS version 22. To see the change over a period of time, McNemar test for categorical data and repeated measure for continuous data followed by post hoc comparison by Bonferroni method were used. The mean age of the patients was 46.98 ± 13.33 years. The mean diameter of the cephalic vein, ulnar artery, and radial artery at the wrist was 1.733 ± 0.528, 1.700 ± 0.364, and 1.908 ± 0.420, respectively, whereas the mean diameter of the cephalic vein, ulnar artery, and radial artery at the forearm was 1.952 ± 0.488, 1.910 ± 0.421, and 2.058 ± 0.458, respectively. Immediate thrill after the surgery was present in 36/52 (69.2%) of the patients. The radial artery diameter at the wrist was significantly less in the patients with primary failure in whom immediate thrill was not present (P = 0.016). At 1-month follow-up, 30/49 (61.2%) and, at 6 months, 29/48 (60.4%) fistulas were functional. Radiocephalic AV fistulas have a reasonable success rate and minimal morbidity, and radial artery diameter is a good predictor of the outcome.

    Abstract SARS-CoV-2 affects the nervous system directly by neurotoxic action, by binding to angiotensin-converting enzyme-2 (ACE2) receptors or indirectly by inducing cytokine storm leading to disruption of the blood-brain barrier, immunological mediation, increasing blood coagulation and as a trigger for autoimmune-mediated demyelinating injuries in the central nervous system. In COVID-19 neuro-ophthalmological manifestations are not so common. Optic neuritis is the result of optic nerve inflammation and has varied causes. In many patients, signs of inflammation are not visible on the fundus, and it usually manifests as papillitis-anterior neuritis, retrobulbar neuritis or visible optic nerve oedema. We are reporting a case of a middle-aged adult diagnosed with myelin oligodendrocyte glycoprotein (MOG) antibody-positive optic neuritis of the right eye post-COVID-19 disease. Routine biochemical and haematological investigations, including electrolytes and hepatic and renal functions, were normal. In cerebrospinal fluid (CSF) - glucose 63.8 mg/dL, protein 39.1 mg/dL and ADA - 1 µ/L. No oligoclonal bands of immunoglobulin G (IgG) were seen on high-resolution electrophoresis. Serum Anti-MOG-antibodies were positive. A gadolinium-contrast magnetic resonance imaging (MRI) of the brain and orbits shows post-contrast enhancement in the superior aspect of the right intraconal soft tissue. The right optic nerve appears bulky and heterogeneous with peripheral post-contrast enhancement along its entire length suggestive of neuritis. A diagnosis of MOG antibody-positive optic neuritis was made, and the patient was treated with an injection of Methylprednisolone with intravenous immunoglobulin. Each day, the evaluation of the right eye showed remarkable improvement from finger counting to 6/6 vision. The patient was discharged on the 9th day of admission. We can conclude that early diagnosis was essential for improving the long-term outcome of the patient.

    Abstract The knowledge of different anatomic venous variants of central vessels is essential to improve the safety of procedures like central venous access and tunneled central catheter (TCC) placement. Persistent left superior vena cava (PLSVC) is an uncommon variant seen in 0.5 to 2% of common population, in 80 to 90% of which PLSVC commonly drains into the right atrium (RA) via the coronary sinus. We describe a rare case of PLSVC draining into RA through common channel with suprahepatic inferior vena cava, encountered while placing TCC into left internal jugular vein. This report highlights the radiological findings and the implications of this anatomic anomaly.

    Abstract Background With the improvement in noninvasive diagnostic imaging modalities, Endoscopic Retrograde Cholangio-Pancreatography (ERCP) has evolved into a primarily therapeutic procedure. Besides being efficacious and one of the most commonly done procedures, ERCP is also associated with a high risk of complications. However, there is a lack of studies analyzing the safety and success of ERCP in patients with liver cirrhosis. We retrospectively evaluated the outcome of ERCP in patients with cirrhosis of the liver compared to non-cirrhotic patients using the database from our institute. Methods Patients with liver cirrhosis who underwent ERCP from January 2010 to March 2020 were analyzed. This was a matched case-control study in which one cirrhotic patient undergoing ERCP was age and gender-matched randomly to one non-cirrhotic patient. We compared adverse events and the success rate of ERCP between cirrhotic patients and non-cirrhotic patients. The primary outcome of the study was analyzing the prevalence of procedure-related adverse events and their independent risk factors in patients of cirrhosis compared to the non-cirrhotic population. Results Two hundred patients were analyzed in both groups. Choledocholithiasis was the most common reason for ERCP in both groups. Mean Child-Turcotte-Pugh (CTP) score and Model for End-stage Liver Disease (MELD) score in the cirrhosis group were 9.16 ±1.78 and 19.09 ±7.06 respectively. Patients in the cirrhosis group had a significantly higher frequency of complications compared to the controls: 41 (20.5 %) versus 15 (7.5%), p < 0.01. Bleeding was the most common adverse event in both groups: 19 (9.5%) vs 6(3%). High International Normalised Ratio (INR), low platelets, and cholangitis at presentation were independently predictive of post-ERCP complications. Despite a similar technical success rate, the clinical success rate was lower in the cirrhotic than in the noncirrhotic group (83.9% versus 97.9%, p=0.006). Conclusion The prevalence of complications following ERCP was nearly three-fold higher in patients with cirrhosis than in non-cirrhotic patients. These events were related primarily to cholangitis, coagulopathy, and the advanced status of chronic liver disease.

    Abstract Introduction Klebsiella pneumonia is one of the most prevalent bacteria that cause nosocomial infections, particularly in critically ill patients in the intensive care unit (ICU). Multi-drug-resistant Klebsiella pneumoniae (MDRKP) has become an urgent risk to public health as its prevalence has sharply surged around the globe in recent decades. Therefore, this research was conducted to evaluate shifts over a four-year period in drug susceptibility patterns among Klebsiella pneumoniae isolates from mechanically ventilated intensive care unit patients. Materials and methods This is a retrospective observational study conducted in a tertiary care multi-specialty hospital and teaching institute in North India and was approved by the institutional ethics committee. The research comprised Klebsiella pneumoniae isolates from endotracheal aspirates (ETA) of patients on mechanical ventilation admitted to the general intensive care unit (ICU) of our tertiary care facility. The data from January to June 2018 and January to June 2022 were collected. According to the antimicrobial resistance profile of the strains, they were categorized as susceptible, resistant to one or two antimicrobial categories, multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant (PDR). The criteria for MDR, XDR, and PDR were proposed by the European Centre for Disease Prevention and Control (ECDC). IBM Statistical Package for the Social Sciences (SPSS) for Windows, Version 24.0, Armonk, NY, IBM Corp., was used for data input and analysis. Results A total of 82 cases of Klebsiella pneumonia were included in the study. Of these 82 isolates, 40 were isolated over a period of six months from January to June 2018, and the remaining 42 were isolated from January to June 2022. Among the 2018 group, five strains (12.5%) were classified as susceptible, three (7.5%) as resistant, seven (17.5%) as MDR, and 25 (62.5%) as XDR. The highest percentages of antimicrobial resistance in the 2018 group were observed with amoxicillin/clavulanic acid (90%), ciprofloxacin (100%), piperacillin/tazobactam (92.5%), and cefoperazone/sulbactam (95%). In comparison, the 2022 group showed no strain as susceptible; nine strains (21.4%) were classified as resistant; three strains (7%) as MDR; and 30 strains (93%) were classified as XDR. There was a significant increase in resistance to amoxicillin, from 10% in 2018 to nil in 2022. Overall, the rate of resistant Klebsiella pneumonia (K. pneumonia) increased from 7.5% (3/40) in 2018 to 21.4% (9/42) in 2022, while XDR Klebsiella pneumonia among the mechanically ventilated ICU patients significantly increased from 62.5% (25/40) in 2018 to 71% (30/42) in 2022. Conclusion  K. pneumoniae antibiotic resistance is a real threat in Asia and requires close monitoring to be controlled. More careful attempts should be made to create a new generation of antimicrobials since the prevalence of resistance to existing medications is rising. Antibiotic resistance should be monitored and reported by healthcare institutions regularly.
