Determining the impact of an artificial intelligence tool on the management of pulmonary nodules detected incidentally on CT (DOLCE) study protocol: a prospective, non-interventional multicentre UK study.

INTRODUCTION: In a small percentage of patients, pulmonary nodules found on CT scans are early lung cancers. Lung cancer detected at an early stage has a much better prognosis. The British Thoracic Society guideline on managing pulmonary nodules recommends using multivariable malignancy risk prediction models to assist in management. While these guidelines seem to be effective in clinical practice, recent data suggest that artificial intelligence (AI)-based malignant-nodule prediction solutions might outperform existing models. METHODS AND ANALYSIS: This study is a prospective, observational multicentre study to assess the clinical utility of an AI-assisted CT-based lung cancer prediction tool (LCP) for managing incidental solid and part solid pulmonary nodule patients vs standard care. Two thousand patients will be recruited from 12 different UK hospitals. The primary outcome is the difference between standard care and LCP-guided care in terms of the rate of benign nodules and patients with cancer discharged straight after the assessment of the baseline CT scan. Secondary outcomes investigate adherence to clinical guidelines, other measures of changes to clinical management, patient outcomes and cost-effectiveness. ETHICS AND DISSEMINATION: This study has been reviewed and given a favourable opinion by the South Central-Oxford C Research Ethics Committee in UK (REC reference number: 22/SC/0142).Study results will be available publicly following peer-reviewed publication in open-access journals. A patient and public involvement group workshop is planned before the study results are available to discuss best methods to disseminate the results. Study results will also be fed back to participating organisations to inform training and procurement activities. TRIAL REGISTRATION NUMBER: NCT05389774.

Effect of dentin roughening and type of composite material on the restoration of non-carious cervical lesions: an in vivo study with 18 months of follow-up.

Objectives: The purpose of this study was to evaluate the impact of dentin roughening and the type of composite resin used (either bulk-fill flowable or nanohybrid) on the restoration of non-carious cervical lesions (NCCLs) with an 18-month follow-up period. Materials and Methods: This prospective split-mouth study included 36 patients, each with a minimum of 4 NCCLs. For each patient, 4 types of restorations were performed: unroughened dentin with nanohybrid composite, unroughened dentin with bulk-fill flowable composite, roughened dentin with nanohybrid composite, and roughened dentin with bulk-fill flowable composite. A universal bonding agent (Tetric N Bond Universal) was applied in self-etch mode for all groups. The restorations were subsequently evaluated at 6, 12, and 18 months in accordance with the criteria set by the FDI World Dental Federation. Inferential statistics were computed using the Friedman test, with the level of statistical significance established at 0.05. Results: The 4 groups exhibited no significant differences in relation to fracture and retention, marginal staining, marginal adaptation, postoperative hypersensitivity, or the recurrence of caries at any follow-up point. Conclusions: Within the limitations of the present study, over an 18-month follow-up period, no significant difference was present in the clinical performance of bulk-fill flowable and nanohybrid composite restorations of non-carious cervical lesions. This held true regardless of whether dentin roughening was performed.

Cost-effectiveness of decellularised bone allograft compared with fresh-frozen bone allograft for acetabular impaction bone grafting during a revision hip arthroplasty in the UK.

OBJECTIVES: Fresh-frozen allograft is the gold-standard bone graft material used during revision hip arthroplasty. However, new technology has been developed to manufacture decellularised bone with potentially better graft incorporation. As these grafts cost more to manufacture, the aim of this cost-effectiveness study was to estimate whether the potential health benefit of decellularised bone allograft outweighs their increased cost. STUDY DESIGN: A Markov model was constructed to estimate the costs and the quality-adjusted life years of impaction bone grafting during a revision hip arthroplasty. SETTING: This study took the perspective of the National Health Service in the UK. PARTICIPANTS: The Markov model includes patients undergoing a revision hip arthroplasty in the UK. INTERVENTION: Impaction bone grafting during a revision hip arthroplasty using either decellularised bone allograft or fresh-frozen allograft. MEASURES: Outcome measures included: total costs and quality-adjusted life years of both interventions over the lifetime of the model; and incremental cost-effectiveness ratios for both graft types, using base case parameters, univariate sensitivity analysis and probabilistic analysis. RESULTS: The incremental cost-effectiveness ratio for the base case model was found to be £270 059 per quality-adjusted life year. Univariate sensitivity analysis found that changing the discount rate, the decellularised bone graft cost, age of the patient cohort and the revision rate all had a significant effect on the incremental cost-effectiveness ratio. CONCLUSIONS: As there are no clinical studies of impaction bone grafting using a decellularised bone allograft, there is a high level of uncertainty around the costs of producing a decellularised bone allograft and the potential health benefits. However, if a decellularised bone graft was manufactured for £2887 and lowered the re-revision rate to less than 64 cases per year per 10 000 revision patients, then it would most likely be cost-effective compared with fresh-frozen allograft.

Comparative assessment of the outcome of complete pulpotomy using mineral trioxide aggregate and Biodentine in mature permanent mandibular molars with symptomatic irreversible pulpitis: A randomized clinical trial with 18 months of follow-up.

Background: Mature permanent teeth with irreversible pulpitis have traditionally been managed with pulpectomy. With advancements in pulp biology and dental materials, many clinicians are using vital pulp therapies like pulpotomy to manage such teeth. The current study was conducted to help clinicians in making decisions about case selection and choice of material for such cases. Aim: This randomized clinical trial evaluated the outcome of complete pulpotomy, using mineral trioxide aggregate (MTA) and Biodentine, in permanent mandibular molars with symptomatic irreversible pulpitis (SIP). Materials and Methods: Fifty patients with moderate-to-severe pain in mandibular molars with SIP were included in this prospective, parallel, single-blind clinical trial. Coronal pulp was completely removed and hemostasis was achieved with a cotton pellet moistened with 2.5% sodium hypochlorite. Subsequently, the radicular orifices were randomly covered with MTA or Biodentine. All teeth were permanently restored with composite restoration at the same appointment. Clinical evaluation was performed at 1 week, 3 months, 6 months, 12 months, and 18 months and radiographic evaluation was done after 6 months, 12 months, and 18 months. Mann-Whitney U and Chi-square tests were utilized for statistical analysis. Results: Success rates of MTA and Biodentine pulpotomy were 63.6% and 69.6%, respectively, with no significant difference between the two groups at any follow-up period (P > 0.05). Conclusion: There were no significant differences in complete pulpotomy success rates between MTA and Biodentine over 18 months in mandibular molars with SIP.

Non-surgical management of dens invaginatus type IIIB in maxillary lateral incisor with three root canals and 6-year follow-up: A case report and review of literature.

BACKGROUND: The presence of dens invaginatus (DI) complicates treatment of any tooth, from diagnosis to access cavity and biomechanical preparation and obturation. Reports of successful non-surgical management of DI type IIIB in maxillary lateral incisor are rare. Here, we report such a case, with three root canals and a long follow-up. CASE SUMMARY: A 13-year-old female patient presented with mild pain in the maxillary right lateral incisor (#7) for 10-15 d. On examination, the tooth was slightly rotated, with slight tenderness on percussion and grade I mobility but with no caries, pockets or restorations and non-vital pulp (via vitality tests). Radiographic examination revealed unusual configuration of the tooth's root canals, with an enamel-lined invagination extending to the apex, suggesting the possibility of DI Oehler's type IIIB and a periapical radiolucency. Widening the access cavity lingually revealed one distinct buccal orifice and two distinct palatal orifices; under higher magnification of a dental operating microscope (DOM), the mesio-palatal and disto-palatal orifices were observed as connected by a C-shaped groove. The root canals were prepared with hand K-files following a step-back technique, and obturated using a combination technique of lateral condensation and vertical compaction. At the 6-year follow-up, the patient was asymptomatic, and the periapical radiography displayed significant healing around the apical end of the root. CONCLUSION: Proper knowledge of unusual root canal anatomy is required in treating DI. Conventional methods of root canal treatment can successfully resolve such complex cases, facilitated by DOM and cone-beam computed tomography.

Comparison of Hemodynamic Changes in Patients Undergoing Laparoscopic Cholecystectomy using rocuronium and vecuronium for Intubation and Maintenance under General Anesthesia.

Context: The context of the study is to compare and find better muscle relaxant between rocuronium and vecuronium for intubation and maintenance under general anesthesia in patients undergoing laparoscopic cholecystectomy. Aims: The aim of the study is to measure intubating condition, hemodynamic changes during intubation and also during maintenance of general anesthesia and to record complications, if any. Settings and Design: A prospective clinical study conducted in the Department of Anesthesiology in tertiary care center. Materials and Methods: A total of 100 patients of the American Society of Anesthesiologists Classes Grade I and II were planned for laparoscopic cholecystectomy were divided into two groups of 50 each. The subjects in the control and study group were put under anesthesia using injection propofol 2.0 mg.kg-1 along with injection vecuronium 0.10 mg.kg-1 and injection propofol 2.0 mg.kg-1 along with injection rocuronium 0.60 mg.kg-1, respectively. Hemodynamic monitoring and oxygen saturation (SPO2) were recorded at various intervals. Statistical Analysis Used: All the collected data were imported into Microsoft Excel, and the statistical analysis was done by using SPSS 25.0 version. Results: The mean heart rate before and after carboperitoneum at different time intervals and before and after extubation was significantly lower in vecuronium group. The mean systolic blood pressure and mean arterial pressure at 1 and 5 minutes after extubation were significantly more among vecuronium group. Conclusions: Rocuronium is reasonably cardiostable, produces excellent intubation conditions, has a shorter duration of action, and shows minimal cumulative effect.

Validation of the STARZ neonatal acute kidney injury risk stratification score in an independent prospective cohort.

OBJECTIVE: A rapid AKI risk assessment score would allow for improving management and outcomes. STARZ (Sethi, Tibrewal, Agrawal, Raina, waZir) score was developed for acute kidney injury (AKI) risk stratification of critically ill neonates. This is the first independent validation for the novel score outside the original enrolled centres. STUDY DESIGN: 750 neonates were included in the study. The STARZ score was calculated after 12 hours of admission. Neonates admitted in NICU and receiving IV fluids for at least 48 hours were included. RESULTS: A total of 8.8% neonates had AKI in the first 7 days post admission. The duration of hospital stay was significantly higher among neonates with AKI [10.5 (7-19) vs. 7 (5-10) days; p < 0.001]. Mortality risk was 6.4 times higher among those with AKI [8 (12.1%) vs. 13 (1.9%); p < 0.001; RR (95% CI): 6.38 (2.74-14.83)]. In this study, the STARZ neonatal scoring model showed a sensitivity of 89.4% in detecting AKI with a 90.9% specificity and a high negative predictive value of 98.9%. The area under ROC was 0.958 (0.934-0981) - a high discriminative power. CONCLUSIONS: The STARZ score allows for AKI risk stratification, providing opportunity for therapeutic interventions which may improve outcomes in critically ill neonates.

Developing a method to capture parental experience in a neonatal surgical centre in the context of COVID-19: a qualitative study.

INTRODUCTION: Improved parental experience is related to improved mental and physical health outcomes for the infant. The COVID-19 pandemic abruptly impacted on healthcare delivery and services need information to shape how to manage the disruption and recovery. METHODS: Our aim was to develop a systematic process to capture parents' experience of their neonatal surgical healthcare journey during the pandemic. We identified relevant stakeholders and using semistructured interviews, we explored three key themes.(1) How to recruit and collect data from representative parents?(2) What questions should be asked?(3) How to disseminate results for service development? RESULTS: Responses indicated the need to involve 'difficult to access groups' (eg, first language not English, high social deprivation, low health literacy), defined the range of family and patient characteristics variables to be considered for representative responses (eg, antenatal diagnosis, disease complexity, number of siblings, single parent, parental health). The proposed questions were grouped into five main topics: information preadmission; in-patient experience; support during admission; the effect of COVID-19; discharge and posthospital experience. Recommendations for dissemination included local, regional and national fora as well as the need to feedback to participants about the changes made.Based on the analysis, we developed a semistructured interview which underwent cognitive testing, prepilot and pilot phase testing. DISCUSSION: This protocol is grounded in the views of relevant stakeholders to ensure it captures relevant information in a pragmatic but methodologically sound way. It will next be used to assess parental experience in a large neonatal surgical unit. We hope that the protocol could be adapted and used by other groups.

Evaluation of Health-Related Quality of Life in Adult Patients on Hemodialysis.

BACKGROUND: Hemodialysis in end-stage renal disease patients causes disability in different domains of patient's lives, leading to impaired (quality of life [QOL]). Studies measuring the QOL in patients on renal replacement therapy are limited in the Indian scenario. AIMS: To evaluate the QOL in adult patients on maintenance hemodialysis by applying the World Health Organization QOL (WHOQOL)-BREF scale. MATERIAL AND METHODS AND STUDY DESIGN: Health-related QOL was evaluated in 100 adult patients on maintenance haemodialysis for 3 months or more in Dayanand Medical College and Hospital, Ludhiana. The WHOQOL-BREF was applied in these patients and the physical, psychological, social, and environmental health domains were assessed. RESULTS: Most common age group was 31-60 years (56%) with a mean age of 54.44 years, male: 74%. Patients with age more than 60 years had better QOL scores in the social domain which was statistically significant (P = 0.005). Male patients had better scores in all four domains and was significant in the social domain (P = 0.025). Married patients had better QOL scores in social domain. Duration of dialysis had a reverse correlation with QOL scores in physical domain with better scores in dialysis duration of <12 months. Frequency of dialysis did not significantly affect the QOL scores. QOL scores were directly related to the monthly family income in all four domains with the highest income group showing better scores (P < 0.05). CONCLUSION: The present study provided an insight into the factors that affect the QOL in hemodialysis patients. Patients with age >60 years had better QOL scores in the social domain. Female gender, low serum proteins, HD duration of more than 1 year, and low monthly income were found to be associated with impaired QOL domains in patients undergoing maintenance hemodialysis.

Comparison of Clinical Features and Outcome of Dengue Fever and Multisystem Inflammatory Syndrome in Children Associated With COVID-19 (MIS-C).

OBJECTIVE: To identify clinical and laboratory features that differentiate dengue fever patients from MIS-C patients and determine their outcomes. Methods: This comparative cross-sectional study was done at a tertiary care teaching institute. We enrolled all hospitalized children aged 1 month - 18 years and diagnosed with either MIS-C and/or dengue fever according to WHO criteria between June and December, 2020. Clinical and laboratory features and outcomes were recorded on a structured proforma. RESULTS: During the study period 34 cases of MIS-C and 83 cases of Dengue fever were enrolled. Mean age of MIS-C cases (male, 86.3%) was 7.89 (4.61) years. MIS-C with shock was seen in 15 cases (44%), MIS-C without shock in 17 cases (50%) and Kawasaki disease-like presentation in 2 cases (6%). Patients of MIS-C were younger as compared to dengue fever (P=0.002). Abdominal pain and erythematous rash were more common in dengue fever. Of the inflammatory markers, mean C reactive protein was higher in MIS-C patients [100.2 (85.1) vs 16.9 (29.3) mg/dL] (P<0.001). In contrast, serum ferritin levels were higher in dengue fever patients (P=0.03). Mean hospital stay (patient days) was longer in MIS- C compared to dengue fever (8.6 vs 6.5 days; P=0.014). CONCLUSION: Clinical and laboratory features can give important clues to differentiate dengue fever and MIS-C and help initiate specific treatment.

Oral cyclophosphamide therapy in 100 children with steroid-sensitive nephrotic syndrome: experience from a developing country.

BACKGROUND: Oral cyclophosphamide (CYP) is an important therapeutic agent in treatment of steroid-sensitive nephrotic syndrome having a steroid-dependent (SD) or frequent relapsing (FR) course. This retrospective observational study aimed to determine response to oral CYP and factors associated with positive response in these patients. METHODS: We studied 100 children (male; 75) with FR (19%) and SD (81%) NS treated with CYP in the Pediatric Nephrology clinic. Responders were defined as children in whom steroids were stopped for at least 6 months following CYP and factors affecting response were analysed. Relapse-free survival was estimated by Kaplan-Meier method. RESULTS: Median age at onset of NS was 3 years (IQR 2-5.2). Median age at CYP was 5.7 years (IQR 3.7-7.9). Fifty percent of patients were in the responder group at 6 months of CYP. Relapse-free survival post CYP therapy was 31% at 1 year, 11% at 2 years. Factors predicting good response were age at onset of NS > 3 years with 61.2% response at 6 months (p = 0.028) and older age at CYP initiation (> 5 years) with 61% response (p = 0.008). Multivariate regression analysis showed age at start of CYP > 5 years was an independent factor for good response (p = 0.044, OR = 2.903, CI -1.03 to 8.18). CONCLUSIONS: Judicious selection of patients, especially with age of onset of NS more than 3 years and initiation of CYP after age of 5 years, can predict better response in this group of patents.

Arbuscular mycorrhiza in combating abiotic stresses in vegetables: An eco-friendly approach.

Vegetable production is hampered by several abiotic stresses which are very common in this era of climate change. There is a huge pressure on the plants to survive and yield better results even in the prevalence of various environmental stresses such as cold stress, drought, heat stress, salinity etc. This necessitates the need of robust plant growth which is possible with mycorrhizal association. Mycorrhiza improves plants tolerance to several abiotic stresses by various physiological, functional and biochemical changes in plants. The application of arbuscular mycorrhiza (AM) as vegetable biofertilizers doesn't only influence the plant health, but moreover discursively it lowers the demand for harmful chemical fertilizers. Overall, it may be concluded that inoculation of vegetables with arbuscular mycorrhizal fungi can be used, as it easily guards plants against undesirable abiotic stresses. In this work, information is provided based on several examples from the literature based on the application of AM to combat harmful abiotic stresses in vegetable crops. This paper reviews the impacts of AM fungi on the plant parameters, its functional activities and molecular mechanisms which makes it more adaptable and underline the future prospects of using AM fungi as a biofertilizer in the stress condition.

Evaluating Combined Effect of Oral Premedication with Ibuprofen and Dexamethasone on Success of Inferior Alveolar Nerve Block in Mandibular Molars with Symptomatic Irreversible Pulpitis: A Prospective, Double-blind, Randomized Clinical Trial.

INTRODUCTION: The success rate of inferior alveolar nerve block decreases exorbitantly in teeth with symptomatic irreversible pulpitis. The purpose of this prospective, double-blind, randomized clinical trial was to evaluate the combined effect of oral premedication with ibuprofen and dexamethasone on the success rate of inferior alveolar nerve block in mandibular molars with symptomatic irreversible pulpitis. METHODS: Ninety-four adult patients actively experiencing pain and diagnosed with symptomatic irreversible pulpitis willingly participated in this study. Preoperative pain was recorded on the Heft-Parker visual analog scale. Patients were randomly allocated to 4 different groups and received placebo, 0.5 mg dexamethasone, 800 mg ibuprofen, or a combination of 0.5 mg dexamethasone and 800 mg ibuprofen. One hour after oral premedication, all patients received standard inferior alveolar nerve block containing 2% lignocaine with 1:200,000 adrenaline. Access cavity preparation was initiated 15 minutes after the administration of anesthesia. Pain scores were recorded on VAS after anesthesia, at dentin penetration to pulp chamber opening, and on file placement. Success was defined as no or mild pain (0-54 mm) throughout the procedure. RESULTS: The chi-square test was used for qualitative data comparison. The 1-way analysis of variance test and post hoc Bonferroni test showed a statistically significant difference between the combination of 0.5 mg dexamethasone and 800 mg ibuprofen group and the other 3 groups (P < .001). CONCLUSIONS: Preoperative administration of a combination of dexamethasone and ibuprofen improved the success rate of inferior alveolar nerve block in mandibular molars with symptomatic irreversible pulpitis.

Multidisciplinary Approach for the Management of Mandibular Canines with Rare Configuration.

It is very rare (2%-6% cases) for a mandibular canine to have two root canals and the incidence of finding two roots with two root canals in a mandibular canine that too bilaterally is almost negligible. This case report discusses the presence and multidisciplinary management of such rarest configuration in both mandibular canines of a female patient. This case shows the importance of recognition of anatomical variations in successful accomplishment of root canal treatment.

Biogasoline production from linoleic acid via catalytic cracking over nickel and copper-doped ZSM-5 catalysts.

Catalytic cracking of vegetable oil mainly processed over zeolites, and among all the zeolites particularly HZMS-5 has been investigated on wide range for renewable and clean gasoline production from various plant oils. Despite the fact that HZSM-5 offers a higher conversion degree and boost aromatics yield, the isomerate yield reduces due to high cracking activity and shape selectivity of HZSM-5. Hence, to overcome these problems, in this study the transition metals, such as nickel and copper doped over HZSM-5 were tested for its efficiencies to improve the isoparaffin compounds. The catalysts were screened with linoleic acid in a catalytic cracking reaction conducted at 450 ᵒC for 90 min in an atmospheric condition in batch reactor. Then, the gasoline composition of the organic liquid product (OLP) was analysed in terms of paraffin, isoparaffin, olefin, naphthenes and aromatics (PIONA). The results showed that Cu/ZSM-5 produced the highest liquid yield of 79.1%, at the same time reduced the production of gas and coke to 18.8% and 0.7%. Furthermore, the desired isoparaffin composition in biogasoline increased from 1.6% to 6.8% and at the same time reduced the oxygenated and aromatic compounds to 15.4% and 59.7%, respectively. The linoleic acid as model compound of rubber seed oil, in the catalytic cracking reaction provides a clearer understanding of the process. Besides, the water gas shift (WGS) reaction in catalytic cracking reaction provides insitu hydrogen production to saturate the branched olefin into the desired isoparaffin and the aromatics into naphthenes.

The role of ramosetron in the prevention of post-spinal shivering in obstetric patients. A prospective randomized double blind study.

BACKGROUND AND AIM: Intra/post-operative shivering is frequently observed in parturients posted for elective cesarean delivery (C/D) under spinal anaesthesia. Several studies have advocated the anti-shivering effect of 5-HT3 antagonists, although none has revealed convincing results. The study aims to evaluate the prophylactic effect of a single intravenous dose of ramosetron (0.3 mg), compared with a placebo (N - normal saline), for the prevention of post-spinal shivering (PSS) during elective C/D. METHOD: The study comprised 80 parturients of the American Society of Anaesthesiologists (ASA) physical status I/II, posted for elective C/D under spinal anaesthesia who were randomly divided into 2 equal groups; Group N: 0.9% normal saline (4 ml) immediately before induction of spinal anaesthesia and Group R: ramosetron (0.3 mg) intravenously diluted to 4 ml volume. Shivering at any time on a (0-4) scale and total dose of tramadol required for its treatment was recorded. The study also includes the recording of haemodynamic parameters and the incidence of early onset nausea and vomiting. RESULTS: Statistically significant data was obtained while comparing incidence of shivering and maximum shivering at any time (P = 0.001). A lower incidence of early onset nausea and decreased total dose of tramadol was also observed in the ramosetron group. CONCLUSION: Ramosetron (0.3 mg) is advocated to be an effective drug in preventing post-spinal shivering among parturients posted for elective C/D. Moreover, its role in preventing maternal nausea together with better haemodynamic parameters further supported the advantageous role of ramosetron in our group of patients.

Production of gasoline range hydrocarbons from catalytic cracking of linoleic acid over various acidic zeolite catalysts.

Employment of edible oils as alternative green fuel for vehicles had raised debates on the sustainability of food supply especially in the third-world countries. The non-edible oil obtained from the abundantly available rubber seeds could mitigate this issue and at the same time reduce the environmental impact. Therefore, this paper investigates the catalytic cracking reaction of a model compound named linoleic acid that is enormously present in the rubber seed oil. Batch-scale experiments were conducted using 8.8 mL Inconel batch reactor having a cyclic horizontal swing span of 2 cm with a frequency of 60 cycles per minute at 450 °C under atmospheric condition for 90 min. The performance of HZSM-5, HBeta, HFerrierite, HMordenite and HY catalysts was tested for their efficiency in favouring gasoline range hydrocarbons. The compounds present in the organic liquid product were then analysed using GC-MS and classified based on PIONA which stands for paraffin, isoparaffin, olefin, naphthenes and aromatics respectively. The results obtained show that HZSM-5 catalyst favoured gasoline range hydrocarbons that were rich in aromatics compounds and promoted the production of desired isoparaffin. It also gave a higher cracking activity; however, large gaseous as by-products were produced at the same time.

Unipept 4.0: Functional Analysis of Metaproteome Data.

Unipept ( https://unipept.ugent.be ) is a web application for metaproteome data analysis, with an initial focus on tryptic-peptide-based biodiversity analysis of MS/MS samples. Because the true potential of metaproteomics lies in gaining insight into the expressed functions of complex environmental samples, the 4.0 release of Unipept introduces complementary functional analysis based on GO terms and EC numbers. Integration of this new functional analysis with the existing biodiversity analysis is an important asset of the extended pipeline. As a proof of concept, a human faecal metaproteome data set from 15 healthy subjects was reanalyzed with Unipept 4.0, yielding fast, detailed, and straightforward characterization of taxon-specific catalytic functions that is shown to be consistent with previous results from a BLAST-based functional analysis of the same data.
