RESUMO

INTRODUCTION:  There are several operative modes to address hand fractures to gain better anatomical and functional results including external fixator, percutaneous K-wire fixation, lag screw fixation, tension band wiring, intra-medullary nails or wires, and plate-screw fixation. We evaluated the results of plate osteosynthesis in fractures of metacarpals and phalanges in a prospective manner. MATERIAL AND METHODS:  A total 50 adults (19-60 years) of either sex having 58 fractures managed by miniature plate osteosynthesis and followed for a minimum six months (6-19), including metacarpal and phalangeal fractures (unstable or serial fractures), intra-articular fractures, fracture-dislocation of proximal interphalangeal and distal interphalangeal joints with joint incongruity or subluxation were enrolled while contaminated compound fractures, pathological fractures and cases of reimplantation were excluded from study. Clinical assessment was done using the American Society for Surgery of the Hand (ASSH), total active flexion (TAF), total active range of motion (TAM) score, and the Disabilities of the Arm, Shoulder, and Hand (quick DASH) score while sequential radiographs were done at each follow-up. RESULT: All the fractures had perfect union clinically as well as radiologically with a mean duration of six weeks while functional outcomes in reference to clinical scores were observed excellent and fair in all cases. None of the cases had any loss of reduction, loosening of the implant, or other major complications. CONCLUSIONS: Miniature plate fixation provides enough stability in metacarpal and phalanges fractures, thereby allowing immediate active movements, which leads to excellent functional outcomes and early return to normal activities.

RESUMO

Generally, financial investments are necessary for portfolio management. However, the prediction of a portfolio becomes complicated in several processing techniques which may cause certain issues while predicting the portfolio. Moreover, the error analysis needs to be validated with efficient performance measures. To solve the problems of portfolio optimization, a new portfolio prediction framework is developed. Initially, a dataset is collected from the standard database which is accumulated with various companies' portfolios. For forecasting the benefits of companies, a Multi-serial Cascaded Network (MCNet) is employed which constitutes of Autoencoder, 1D Convolutional Neural Network (1DCNN), and Recurrent Neural Network (RNN) is utilized. The prediction output for the different companies is stored using the developed MCNet model for further use. After predicting the benefits, the best company with the highest profit is selected by Integration of Artificial Rabbit and Hummingbird Algorithm (IARHA). The major contribution of our work is to increase the accuracy of prediction and to choose the optimal portfolio. The implementation is conducted in Python platform. The result analysis shows that the developed model achieves 0.89% and 0.56% regarding RMSE and MAE measures. Throughout the analysis, the experimentation of the developed model shows enriched performance.

RESUMO

PURPOSE: Teleconsultation services can be used to overcome the barriers imposed by the Covid-19 pandemic in providing basic orthopaedic rehabilitation services. Aim of the study is to compare the effectiveness of rehabilitation provided via outpatient and teleconsultation in patients with mechanical low backache (LBA) and early osteoarthritis (OA) of the knee joint utilizing Patient-Reported Outcome Measures. The satisfaction level of patients receiving teleconsultation will also be assessed. METHODOLOGY: This study was a hospital-based prospective observational study. The study's participants were divided into two groups (Outpatient and Teleconsultation, respectively), and each group was further divided into two subgroups of 100 participants each (Knee-pain subgroup 1; LBA subgroup 2). SF-12 questionnaire, visual analogue scale (VAS) score for pain, and functional outcome scores (KOOS score for knee pain and the modified Oswestry Disability Index-MODI for LBA) were assessed at initial presentation and 6 months follow-up. Participants' satisfaction for teleconsultation service was assessed at final follow-up by 5 points Likert scale (5, very satisfied; 1, very dissatisfied). RESULTS: Mean consultation time was significantly longer in the outpatient group (p < 0.001). No statistically significant difference in the VAS score, KOOS score (58.0 ± 7.6 vs. 57.8 ± 9.2; p = 0.893), and MODI Score (24.7 ± 13.3 vs. 27.4 ± 12.4; p = 0.128) between the corresponding subgroups of the two groups at final follow-up. Eighty-seven percentage of the participants were satisfied (Likert score ≥ 4) with the teleconsultation services. CONCLUSION: Teleconsultation is equally effective to that as face-to-face outpatient consultation in the rehabilitation of patients with early OA knee and mechanical LBA. LEVEL OF STUDY: Level 2, Prospective comparative study.

RESUMO

As the spectre of climate change gains in strength with each passing moment, many of our mundane food crops like rice face the heat, leading to uncertain yields and unforeseen disease outbreaks. Subsequently, mankind is forced to look for alternative food choices that should primarily come from indigenous plants that are less demanding in terms of usage of water and application of chemical-based fertilizers/pesticides. There are plants growing in the wild in the arid and semi-arid zones of Rajasthan, India, that can come to the rescue, with an added potential for development into valuable functional foods-i.e., not only as source of carbohydrates, proteins, and micro-nutrients but also that of health benefiting nutraceuticals (like antioxidant flavonoids) and relevant enzymes. The other parts (non-edible) of these plants have often also been traditionally validated via diverse ethnomedicinal practices; these could also be useful bioenergy sources. Keeping in mind the broader aim of looking at future functional foods that are also required to be environmentally sustainable, the current report: (a) reviews the extant literature on underutilized legumes from arid/semi-arid zones, (b) discusses current status with respect to biological activities present therein, and (c) suggests pertinent research questions and solution paths in the domains of bioactives, bioenergy, and sustainable environment.

RESUMO

The use of enzymes to accelerate chemical reactions for the synthesis of industrially important products is rapidly gaining popularity. Biocatalysis is an environment-friendly approach as it not only uses non-toxic, biodegradable, and renewable raw materials but also helps to reduce waste generation. In this context, enzymes from organisms living in extreme conditions (extremozymes) have been studied extensively and used in industries (food and pharmaceutical), agriculture, and molecular biology, as they are adapted to catalyze reactions withstanding harsh environmental conditions. Enzyme engineering plays a key role in integrating the structure-function insights from reference enzymes and their utilization for developing improvised catalysts. It helps to transform the enzymes to enhance their activity, stability, substrates-specificity, and substrate-versatility by suitably modifying enzyme structure, thereby creating new variants of the enzyme with improved physical and chemical properties. Here, we have illustrated the relatively less-tapped potentials of plant enzymes in general and their sub-class of extremozymes for industrial applications. Plants are exposed to a wide range of abiotic and biotic stresses due to their sessile nature, for which they have developed various mechanisms, including the production of stress-response enzymes. While extremozymes from microorganisms have been extensively studied, there are clear indications that plants and algae also produce extremophilic enzymes as their survival strategy, which may find industrial applications. Typical plant enzymes, such as ascorbate peroxidase, papain, carbonic anhydrase, glycoside hydrolases and others have been examined in this review with respect to their stress-tolerant features and further improvement via enzyme engineering. Some rare instances of plant-derived enzymes that point to greater exploration for industrial use have also been presented here. The overall implication is to utilize biochemical clues from the plant-based enzymes for robust, efficient, and substrate/reaction conditions-versatile scaffolds or reference leads for enzyme engineering.

RESUMO

The global prevalence of obesity-related systemic disorders, including non-alcoholic fatty liver disease (NAFLD), and cancers are rapidly rising. Several of these disorders involve peroxisome proliferator-activated receptors (PPARs) as one of the key cell signaling pathways. PPARs are nuclear receptors that play a central role in lipid metabolism and glucose homeostasis. They can activate or suppress the genes responsible for inflammation, adipogenesis, and energy balance, making them promising therapeutic targets for treating metabolic disorders. In this study, an attempt has been made to screen novel PPAR pan-agonists from the ZINC database targeting the three PPAR family of receptors (α, γ, ß/δ), using molecular docking and molecular dynamics (MD) simulations. The top scoring five ligands with strong binding affinity against all the three PPAR isoforms were eprosartan, canagliflozin, pralatrexate, sacubitril, olaparib. The ADMET analysis was performed to assess the pharmacokinetic profile of the top 5 molecules. On the basis of ADMET analysis, the top ligand was subjected to MD simulations, and compared with lanifibranor (reference PPAR pan-agonist). Comparatively, the top-scoring ligand showed better protein-ligand complex (PLC) stability with all the PPARs (α, γ, ß/δ). When experimentally tested in in vitro cell culture model of NAFLD, eprosartan showed dose dependent decrease in lipid accumulation and oxidative damage. These outcomes suggest potential PPAR pan-agonist molecules for further experimental validation and pharmacological development, towards treatment of PPAR-mediated metabolic disorders.

RESUMO

Climate change has posed a challenge for food security all over the world in the form of fluctuating crop yields and novel disease outbreaks in plants. Human society's overdependence on a few food crops does not seem a wise precedence. There are numerous underutilized/orphan/neglected legumes growing in the Indian desert regions that can come to the rescue and act as balanced and sustainable sources of nutrients and health-benefitting nutraceuticals. However, challenges such as low plant yield, unidentified metabolic pathways and off-flavor in the food products derived from them prevent the realization of their full potential. Conventional breeding techniques are too slow to achieve the desired modifications and cater to the sharply rising demand for functional foods. The novel gene editing tools like CRISPR-Cas provide more precise tool to manipulate the target genes with or without introduction of foreign DNA and therefore, have better chances to be accepted by governments and societies. The current article reports some of the relevant 'gene editing' success stories with respect to nutraceutical and flavor profiles in the popular legumes. It highlights gaps and future potential, along with areas requiring caution, in underutilized edible legumes of the Indian (semi) arid regions like Prosopis cineraria, Acacia senegal and Cyamopsis tetragonoloba.

RESUMO

Background: We studied ankle arthrodesis with a transfibular approach using sagitally spilitted fibula as a biological plate (onlay grafting) as well as other half of fibula as morcellised local interpositional graft (inlay grafting) to achieve bony union. Material and methods: Retrospective clinico-radiological evaluation of 36 operated cases was done at 3, 6, 12 and 30 months follow-ups. Clinically union was considered once ankle became pain free on full weight bearing. Pain assessment was done by using VAS (visual analogue scale) score and functional evaluation was done by AOFAS (American Orthopaedic Foot & Ankle Society) hind foot score preoperatively and at different follow ups. Radiologically, sagittal plane ankle alignment and fusion status was determined at each follow up. Results: Mean age of patients was 40.36 ± 10.56 years (range 18-55), who were evaluated for mean duration of 33.32 ± 11.25 months (range 24-65). Thirty-three (91.7%) ankles were fused adequately and mean duration to achieve bony union was 5.09 ± 1.3 months (range 4-9 months). Mean post-operative AOFAS score at final follow up was 76.65 ± 4.87 in comparison to 45.76 ± 3.38, preoperatively. VAS score improved significantly from 7.8 (pre-operative) to 2.3 (final follow-up). Non-union in three patients (8.3%) and ankle malalignment in one patient was observed. Conclusion: Transfibular ankle arthrodesis achieves excellent bony unions and functional outcomes in severe ankle arthritis. Biologically incompetent fibula that to be judged individually by the operating surgeon to use it as a graft. Patients having inflammatory arthritis have more dissatisfaction than other aetiologies.

RESUMO

Introduction: Phenolic phytochemicals are known for antioxidant-mediated pharmacological effects in various diseases (diabetes, cancer, CVDs, obesity, inflammatory and neurodegenerative disorders). However, individual compounds may not exert the same biological potency as in combination with other phytochemicals. Cyamopsis tetragonoloba (Guar), an underutilized semi-arid legume which has been used as a traditional food in Rajasthan (India), is also a source of the important industrial product guar gum. However, studies on its biological activity, like antioxidant, are limited. Methods: We tested the effect of C. tetragonoloba seed extract to enhance the antioxidant activity of well-known dietary flavonoids (quercetin, kaempferol, luteolin, myricetin, and catechin) and non-flavonoid phenolics (caffeic acid, ellagic acid, taxifolin, epigallocatechin gallate (EGCG), and chlorogenic acid) using DPPH radical scavenging assay. The most synergistic combination was further validated for its cytoprotective and anti-lipid peroxidative effects in in vitro cell culture system, at different concentrations of the extract. LC-MS analysis of purified guar extract was also performed. Results and discussion: In most cases, we observed synergy at lower concentrations of the seed extract (0.5-1 mg/ml). The extract concentration of 0.5 mg/ml enhanced the antioxidant activity of Epigallocatechin gallate (20 µg/ml) by 2.07-folds, implicating its potential to act as an antioxidant activity enhancer. This synergistic seed extract-EGCG combination diminished the oxidative stress nearly by double-fold when compared with individual phytochemical treatments in in vitro cell culture. LC-MS analysis of the purified guar extract revealed some previously unreported metabolites, including catechin hydrate, myricetin-3-galactoside, gossypetin-8-glucoside, and puerarin (daidzein-8-C-glucoside) which possibly explains its antioxidant enhancer effect. The outcomes of this study could be used for development of effective nutraceutical/dietary supplements.

RESUMO

BACKGROUND: The use of social media in orthopaedic surgery and its allied associations has not been studied. There are various associations which are actively engaged in social media platforms to enhance their impact with their users across the globe. We evaluated the social media presence and extent of involvement of orthopaedics journals and their publishing companies, orthopaedics organizations, orthopaedics device firms, and health organizations. MATERIALS AND METHODS: We compiled a global list of orthopaedics journals and publishing companies, orthopaedics organizations, orthopaedics device firms and health organizations affiliated to orthopaedics (USA) through the internet and their reliable online links. All the categories and their contents were screened on various social media networking sites (Facebook, Twitter, and LinkedIn) in terms of their membership, likes, followers and active participation. Comparable variables were selected and compared. RESULTS: Orthopaedics journals corresponding to sports and health were more notable than others on social networking platforms, i.e., British Journal of Sports Medicine and American Journal of Sports Medicine. Medscape, Lancet, and Elsevier being the multispeciality health and information publishing companies have remarkable participation on Facebook, Twitter and LinkedIn. Medtronic has maximum followers on all discussed social networking sites. Mayo Clinic Rochester, Minnesota and Cleveland Clinic, Cleveland, Ohio were more admired than other orthopaedics hospitals on Facebook and Twitter in USA. American Academy of Orthopaedic Surgeons was the most popular society on Facebook and LinkedIn while American Orthopaedics Society for Sports Medicine was most talked about on twitter. CONCLUSIONS: Although the active involvement of orthopaedics journals and their publishers is lower than multispecialty publishing companies but increasing trends were found recently. Orthopaedics organisations and device firms were actively involved on social networking while orthopaedics multispeciality health organizations associated with renowned universities have huge likes or followers. The social networking has the potential to flourish these journals and organisations in the near future as large populations over the globe have been actively participating and growing in their numbers exponentially.

RESUMO

The history of pharmacovigilance started back 169 years ago with the death of a 15- year-old girl, Hannah greener. However, the Thalidomide incident of 1961 brought a sharp change in the pharmacovigilance process, with adverse drug reaction reporting being systematic, spontaneous, and regulated timely. Therefore, continuous monitoring of marketed drugs was essential to ensure the safety of public health. Any observed adverse drug reaction detected by signals was to be reported by the health profession. Moreover, signal detection became the primary goal of pharmacovigilance based on reported cases. Among various methods used for signal detection, the Spontaneous Reporting System was most widely preferred; although, it had the limitation of "under- reporting". Gradually, the World Health Organization collaborating centre and "Uppsala Monitoring Centre" were established in 1978 for international monitoring of drugs. The centre was responsible for operating various databases like vigiflow, vigibase, vigilyze, and vigiaccess. Recently, huge data could be generated through spontaneous reporting linked with computational methods, such as Bayesian Framework, E-Synthesis. Furthermore, drug safety surveillance at an early stage prior to the official alerts or regulatory changes was made possible through social media. In addition, India created a National Pharmacovigilance Program, and Schedule Y of the Drug and Cosmetic Act 1945 was reviewed and amended in 2005. The collaboration of Information Technology and Pharmaceutical Company can further enhance the awareness regarding artificial intelligence in pharmacovigilance, which was in its infancy until 2017. Artificial intelligence helps improve the quality and accuracy of information much quickly.

RESUMO

INTRODUCTION: Consensus is lacking regarding management of posttraumatic infected diaphyseal nonunions of femur following intramedullary nailing. Present study reports outcomes of single stage standardised treatment protocol using monolateral rail external fixator/limb reconstruction system in this type of infected diaphyseal femoral nonunions. METHODS: This retrospective study included 26 patients with mean age of 31.7 years having posttraumatic infected diaphyseal femoral nonunions following intramedullary nailing and managed with radical debridement and monolateral rail fixator. The results were assessed by Association for the Study and Application of the Method of Ilizarov criteria. RESULTS: Mean intraoperative bone gap was 4.34 (range, 2-7) cm. Mean gain in bone length was 4.04 (range, 0-7) cm. Fracture united primarily in 22 cases and after freshening of edges, fixator adjustment and fibular grafting in three more patients. Infection persisted in one patient. Most common complications were superficial pin tract infection (15 patients) and loss of more than 30° knee flexion (13 patients). The bone results were excellent, good, and poor in 15, 9, and 2 patients, respectively. The functional results were excellent, good, fair, and poor in 11,13,1 and 1 patient, respectively. CONCLUSION: Single stage procedure including radical debridement, acute docking, distraction osteogenesis at corticotomy site and stabilization with monolateral rail fixator reliably achieves good to excellent bone and functional results, union and eradication of infection in majority of infected nonunions of femoral diaphysis developing after intramedullary fixation. We recommend acute docking in bone gap ≤ 5 cm.

RESUMO

Background: Hernioplasty, in which a mesh is used to strengthen a weakness or defect in the inguinal wall, has replaced simple tissue repair. As it is associated with low recurrence, it is considered the gold standard and is one of the most common general surgical procedures. The ideal repair should be rapid, safe and simple to do, requires minimal dissection to create sufficient space, be cost-effective and be accompanied by a brief hospital stay, reduced pain, and fewer recurrences. The aim of the present study was to compare the efficacy of 3-stitch mesh fixation with that of traditional Lichtenstein mesh fixation of inguinal hernia repair. Materials and Methods: Between July 2018 and December 2019, 59 cases of primary, uncomplicated inguinal hernias were surgically treated. Both the classical Lichtenstein technique (group A, n = 30) and the Lichtenstein technique with the three-stitch fixation method (group B, n = 29) were used on patients with inguinal hernias. Between the two groups, the mean operative times, post-surgical pain scores, average hospital stays and postoperative complications including recurrence rates were compared. Results: With a P-value of 0.001, the 3-point fixation group (group B) took 3.41 ± 0.58 min less time to fix the mesh than the Lichtenstein group (group A, 5.52 ± 0.59 min). The pain after surgery was much less for participants who had 3-point mesh fixation than for those who had conventional mesh fixation in the early (1, 3, 7 and 15 days after surgery) and late (1 month and 3 months) postoperative periods, with a P-value of 0.0001. When compared to the classical mesh fixation group, the 3-point mesh fixation group had less urinary retention, seroma and swelling. Both groups had the same number of other complications. Conclusions: The three-point hernioplasty is a simple procedure that is easier to adopt, less time-consuming, causes less trauma and has a lower risk of postoperative discomfort including chronic groin pain.

RESUMO

Phenolic compounds include a broad variety of antioxidant plant substances such as flavonoids that have in common an aromatic ring with one or more hydroxyl groups. Nutraceuticals and health food supplements are designed from flavonoids as well as pure phytochemicals, often in isolation. However, studies on synergistic and antagonistic effects of such compounds are relatively few. In the current study, dual combinations prepared from five phenolic compounds (flavonoid and non-flavonoid) including rutin hydrate, quercetin dihydrate, hydroquinone, kaempferol, and resveratrol were tested for their antioxidant activities using DPPH · radical scavenging assay. The synergistic antioxidant interactions among these phenolics were evaluated by comparing their individual antioxidant effect with that obtained by a mixture of two compounds in various ratios. Quercetin dihydrate showed the highest antioxidant activity. Many combinations were found statistically synergistic in particular ratios. Rutin hydrate and resveratrol showed maximum synergy (1:1, 2:1, and 3:1 ratio). Antagonistic interactions were also identified. The results of this study could be used by industries to develop more potent nutraceutical supplements or guide the researchers for further bioactivity validation using in vivo assays.

RESUMO

Obesity is an abnormal fat accumulation disorder in the metabolic syndrome constellation, and a risk factor for diabetes, cardiovascular disorders, non-alcoholic fatty liver disease (NAFLD), and cancer. Nuclear receptors (Peroxisome proliferator-activated receptor, PPAR) are implicated in metabolic syndrome and NAFLD, and have potential for therapeutic targeting. Nuclear receptors are ligand-dependent transcription factors that have diverse roles in metabolism, including regulating genes involved in lipid and glucose metabolism, modulating inflammatory genes, and are crucial for maintaining metabolic flexibility. PPAR activates adipose triglyceride lipase, which then releases fatty acids as ligands for PPAR, indicating the interdependency of nuclear receptors and lipases. Here, molecular docking was performed with selected phytochemical ligands that can bind with PPAR-α/γ (PDB ID: 2ZNN and 2ATH, respectively) using Glide module of Schrodinger software followed by molecular dynamics simulation study using Desmond module, and ADMET analysis. Interestingly, orlistat which is a well-known lipase and fatty acid synthase inhibitor also demonstrated favorable binding affinity with both PPAR-α/γ (-10.96 kcal/mol against PPARα and -10.26 kcal/mol against PPARγ). The highest docking scores were however shown by the flavonoids - rutin (-14.88 kcal/mol against PPARα and -13.64 kcal/mol against PPARγ), and its aglycone, quercetin (-10.08 kcal/mol in PPARα and -9.89 kcal/mol in PPARγ). The other phytochemicals (genistein, esculin, daidzin, naringenin, daidzein, dihydroxy coumarin, hydroquinone) showed lower binding affinity as dual agonists. The anti-obesity effects were experimentally validated in cultured adipocytes, which revealed better lipid inhibition by rutin and quercetin than orlistat (quercetin > rutin > orlistat) pointing to their strong potential in anti-obesity treatment.

RESUMO

The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has drastically affected healthcare delivery to cancer patients, including those with malignant bone tumors, worldwide. Such cancer patients are more susceptible to COVID-19 infection and risk contracting the severe disease, but their holistic tumor management has also suffered a significant impact. Because of the acute shortage of healthcare resources due to their diversion in COVID management, substantial changes are needed in various aspects of management for high-grade tumor patients, particularly in developing countries and population-dense regions, so that their evidence-based appropriate treatment is ensured. Owing to a lack of consensus regarding the ideal course of action for the management of malignant bone tumors in the current situation, many such patients often get neglected, leading to loss of life/limb. This review elaborates on various guidelines proposed by different healthcare organizations and institutes regarding the modified care pathways for malignant bone neoplasms in the current coronavirus pandemic. The early published results of these modified care pathways and the changes in the oncology practice brought about by the pandemic are also discussed.

RESUMO

INTRODUCTION: The purpose of this study was to compare the role of the various surgical modalities ie, Hemiarthroplasty (HA), Dynamic Hip Screw (DHS), Cephalo-medullary nail (CMN) in the management of intertrochanteric fractures in elder patients with comparison of the results and assessment of the complications encountered with each method. METHODS: Total 105 adult patients having intertrochanteric fractures managed during July 2013 to December 2018 at tertiary trauma care centre and followed for minimum 12 months were included in the study. Patients were divided into three groups. Primary hemiarthroplasty was done in 35 patients (group A) while DHS and PFN was done in 35 patients each in group B and group C respectively. Functional evaluation was done using Modified Harris Hip score (HHS) at different intervals while ambulatory function was measured using the Parker Mobility Score. RESULTS: The mean age of patients was 72.14±2.9 years. Mean operative time and blood loss in group A was significantly higher than the other two groups. Hemiarthroplasty group could ambulate earlier than DHS/PFN group. Mean HHS at final follow up was 85.40±7 in group A while in group B and group C these values were 76.36±16.45 and 86.85±10.52 respectively. HHS was significantly higher (P, 0.01) in hemiarthroplasty group in comparison to DHS group. Post-operative complications were comparable in all the groups. CONCLUSION: We support the use of hemiarthroplasty for unstable intertrochanteric fracture in elderly patients with lesser failure rates, early mobilization and better functional outcomes. Early mobilization and less hospital stay should be the goal of every surgical procedure in the elder population.

RESUMO

Flavonoids and isoflavonoids in foods are attracting attention as they are significant antioxidant and phytoestrogenic compounds that are beneficial for human health. In this study, the edible pods of the underutilized desert legume Prosopis cineraria from Rajasthan, India were used to extract flavonoids. The pods from semi-arid zone showed the highest flavonoid content (432 mg Rutin hydrate/gm). UV spectrophotometric analysis was also done to characterize flavonoids. The flavonoids and isoflavonoids were further purified from semi-arid zone plants using column chromatography with Amberlite XAD7HP and Sephadex LH-20. LC-MS analysis revealed the presence of medicinally valuable antioxidant flavonoids and isoflavonoids in the pods, viz. vitexin, puerarin, phloridzin, and daidzein. It was seen that the flavonoids/isoflavonoids are present in the selected legume in different forms i.e. pure aglycone, C-glycoside as well as O-glycoside. This finding makes P. cineraria an attractive source candidate for extraction of these nutraceuticals with a potential for development into functional food.

RESUMO

BACKGROUND: Cefpodoxime Proxetil (CPD) is a broad-spectrum cephalosporin indicated in respiratory and urinary tract infections. CPD is a BCS class IV drug with pH-dependent solubility and has poor bioavailability. This study investigated the challenges of developing ternary components based on solid SNEDDS of CPD for in vitro dissolution rate enhancement and self-solidifying behaviour. METHODS: Tween 80, Transcutol and PEG6000 were employed as surfactants, solvents and solidifiers for a base of ternary components to develop self-solidifying solid SNEDDS, respectively. Ternary phase diagrams were used to characterize solidifying behaviour of ternary components in different proportions. S-SNEDDS formulations were drawn on the solidification areas available in the phase diagram and characterized for IR, XRD, DSC and in vitro drug release in various pH media. RESULTS: Ternary components for the preparation of self-solidifying solid SNEDDS were selected based on drug solubility. FTIR and DSC characterization studies ruled out any drug interaction between CPD and components chosen to prepare S-SNEDDS. CPD was transformed from a crystalline into an amorphous state in ternary dispersions as revealed from XRD data. Optimized formulation (S-S 1) demonstrated more than 95% of drug release irrespective of the pH environments of the medium. Calculation of dissolution efficiency and similarity factors indicate that S SNEDDS resulted in a higher drug dissolution rate over binary dispersion (p<0.01). The stability studies showed that the S SNEDDS were stable in performances and CPD assay. CONCLUSION: The present investigation provides an alternative approach for enhancing the CPD dissolution rate using self-solidifying solid SNEDDS exhibited solidification behaviour at ambient temperature conditions and drug loading, which could be exploited over conventional dosage form.
