RESUMO

Klebsiella pneumoniae, which is among the top three pathogens on WHO's priority list, is one of the gram-negative bacteria that doctors and researchers around the world have fought for decades. Capsular polysaccharide (CPS) protein is extensively recognized as an important K. pneumoniae virulence factor. Thus, CPS has become the most characterized target for the discovery of novel drug candidates. The ineffectiveness of currently existing antibiotics urges the search for potent antimicrobial compounds. Flavonoids are a group of plant metabolites that have antibacterial potential and can enhance the present medications to elicit improved results against diverse diseases without adverse reactions. Henceforth, the present study aims to illustrate the inhibitory potential of flavonoids with varying pharmacological properties, targeting the CPS protein of K. pneumoniae by in silico approaches. The flavonoid compounds (n = 169) were retrieved from the PubChem database and screened using the structure-based virtual screening approach. Compounds with the highest binding score were estimated through their pharmacokinetic effects by ADMET descriptors. Finally, four potential inhibitors with PubChem CID: (4301534, 5213, 5481948, and 637080) were selected after molecular docking and drug-likeness analysis. All four lead compounds were employed for the MDS analysis of a 100 ns time period. Various studies were undertaken to assess the stability of the protein-ligand complexes. The binding free energy was computed using MM-PBSA, and the outcomes indicated that the molecules are having stable interactions with the binding site of the target protein. The results revealed that all four compounds can be employed as potential therapeutics against K. pneumoniae.

RESUMO

BACKGROUND: The Health Planning Process under National Health Mission (NHM) is participatory in nature and the State Programme Implementation Plan (PIP) is an aggregation of District PIPs which is examined and approved by the National Programme Coordination Committee (NPCC), Ministry of Health and Family Welfare, Government of India. Many times there are delays in releasing of Record of Proceedings (ROPs)/approvals. This affects utilisation of NHM funds at district level and below and desired outcomes are not achieved. The present study aims to analyse the process of fund flow, disbursement and utilisation of funds on various components under Reproductive Maternal New born Child and Adolescent Health (RMNCH+A) in the district Gurugram. METHODOLOGY: The study was conducted in the District Gurugram of Haryana State, India. One Community Health Centres (CHCs), two Primary Health Centres (PHCs) and four Sub Health Centres were randomly selected. Primary and secondary data were collected in the study. Medical Officer (I/C), Accounts Staff and Health Workers were interviewed using separate schedules regarding process of disbursement, delays in release and utilisation of funds. Separate checklists were prepared to collect data on availability and utilisation of funds at District, CHC and PHC levels under different components of programme. FINDINGS: Study found that PIP is prepared with inputs from Block level but community participation at (PHC) and below was not present. There was a delay in reaching funds to district due to delayed release of ROPs. Almost 30%-40% of the budget could not be utilised due to delay in receiving of budget. Utilisation of funds was less in some programme activities due to vacant positions project staff. Only 38% and 31% of the funds were utilised under the child health and family planning budget head for the district of Gurugram in the year 2016-17. Accounts staffs were overburdened which affected monitoring of funds utilisation. Budget release from State to District and below was through e-Banking. Auxiliary Nurse Midwives (ANMs) at Sub centre used to get Untied Funds at the end of third quarter. The Government introduced new 18 broad budget heads in NHM Budget for improving utilisation of budget. CONCLUSION: Delayed release of ROPs and erroneous estimation of budget under the programme, very rigid and large number of budget heads poses challenges of understanding and analysing expenditure and affects utilisation of funds under the NHM. Moreover, vacant positions in the programme, unrealistic planning, weak community participation in planning of expenditure and unexplained budget cut in ROPs were main challenges faced by the District.

RESUMO

Staphylococcus aureus is a human bacterial pathogen that can cause a wide range of symptoms. As virulent and multi-drug-resistant strains of S. aureus have evolved, invasive S. aureus infections in hospitals and the community have become one of the leading causes of mortality and morbidity. The development of novel techniques is therefore necessary to overcome this bacterial infection. Vaccines are an appropriate alternative in this context to control infections. In this study, the collagen-binding protein (CnBP) from S. aureus was chosen as the target antigen, and a series of computational methods were used to find epitopes that may be used in vaccine development in a systematic way. The epitopes were passed through a filtering pipeline that included antigenicity, toxicity, allergenicity, and cytokine inducibility testing, with the objective of identifying epitopes capable of eliciting both T and B cell-mediated immune responses. To improve vaccine immunogenicity, the final epitopes and phenol-soluble modulin α4 adjuvant were fused together using appropriate linkers; as a consequence, a multiepitope vaccine was developed. The chosen T cell epitope ensemble is expected to cover 99.14% of the global human population. Furthermore, docking and dynamics simulations were used to examine the vaccine's interaction with the Toll-like receptor 2 (TLR2), revealing great affinity, consistency, and stability between the two. Overall, the data indicate that the vaccine candidate may be extremely successful, and it will need to be evaluated in experimental systems to confirm its efficiency.

RESUMO

The recent global pandemic associated with the highly contagious novel coronavirus (SARS-CoV-2) has led to an unpredictable loss of life and economy worldwide, and the discovery of antiviral drugs is an urgent necessity. For the discovery of new drug leads and for the treatment of various diseases, natural products and purified photochemical from medicinal plants are used. The RNA cap was methylated by two S-adenosyl-L-methionine (SAM)-dependent methyltransferases of SARS coronavirus (SARS-CoV-2), catalyzed by NSP16 2'-O-Mtase. Natural substrate SAM, 128 Phytocompounds retrieved from the Phytocompounds database, and 11 standard FDA-approved HIV drugs reclaimed from the PubChem database are subjected to docking analysis. The docking study was done using AutoDock Vina. Further, admetSAR and DruLiTO servers are used to analyze the drug-likeness properties. The NSP16/10 structure and natural substrate SAM, Phytocompounds Withanolide (WTL), and HIV standard drug Dolutegravir (DLT) as hit compounds were identified by molecular dynamics using the Gromacs GPU-enabled package. To examine the effectiveness of the identified drugs versus COVID-19, further in vitro and in vivo studies are required. Communicated by Ramaswamy H. Sarma.

RESUMO

In this paper, a deep learning algorithm was proposed to ensure the voice call quality of the cellular communication networks. This proposed model was consecutively monitoring the voice data packets and ensuring the proper message between the transmitter and receiver. The phone sends its unique identification code to the station. The telephone and station maintain a constant radio connection and exchange packets from time to time. The phone can communicate with the station via analog protocol (NMT-450) or digital (DAMPS, GSM). Cellular networks may have base stations of different standards, which allow you to improve network performance and improve its coverage. Cellular networks are different operators connected to each other, as well as a fixed telephone network that allows subscribers of one operator to another to make calls from mobile phones to landlines and from landlines to mobiles. The simulation is conducted in Matlab against different performance metrics, that is, related to the quality of service metric. The results of the simulation show that the proposed method has a higher QoS rate than the existing method over an average of 97.35%.

RESUMO

Sorghum is a major grain crop used in traditional meals and health drinks, and as an efficient fuel. However, its productivity, value, germination, and usability are affected by grain mold, which is a severe problem in sorghum production systems, which reduces the yield of harvested grains for consumer use. The organic approach to the management of the disease is essential and will increase consumer demand. Bioactive molecules like mVOC (volatile organic compound) identification are used to unravel the molecules responsible for antifungal activity. The Streptomyces rochei strain (ASH) has been reported to be a potential antagonist to many pathogens, with high levels of VOCs. The present study aimed to study the inhibitory effect of S. rochei on sorghum grain mold pathogens using a dual culture technique and via the production of microbial volatile organic compounds (mVOCs). mVOCs inhibited the mycelial growth of Fusarium moniliforme by 63.75 and Curvularia lunata by 68.52%. mVOCs suppressed mycelial growth and inhibited the production of spores by altering the structure of mycelia in tripartite plate assay. About 45 mVOCs were profiled when Streptomyces rochei interacted with these two pathogens. In the present study, several compounds were upregulated or downregulated by S. rochei, including 2-methyl-1-butanol, methanoazulene, and cedrene. S. rochei emitted novel terpenoid compounds with peak areas, such as myrcene (1.14%), cymene (6.41%), and ç-terpinene (7.32%) upon interaction with F. moniliforme and C. lunata. The peak area of some of the compounds, including furan 2-methyl (0.70%), benzene (1.84%), 1-butanol, 2-methyl-(8.25%), and myrcene (1.12)%, was increased during tripartite interaction with F. moniliforme and C. lunata, which resulted in furan 2-methyl (6.60%), benzene (4.43%), butanol, 2-methyl (18.67%), and myrcene (1.14%). These metabolites were implicated in the sesquiterpenoid and alkane biosynthetic pathways and the oxalic acid degradation pathway. The present study shows how S. rochei exhibits hyperparasitism, competition, and antibiosis via mVOCs. In addition to their antimicrobial functions, these metabolites could also enhance plant growth.

RESUMO

Background and Objective: Data regarding the epidemiology and outcomes of acute kidney injury (AKI) from our part of the world are limited. The irking consequences of AKI, both on the patient and the health care system, are being increasingly recognized. We aimed to study the epidemiology and short-term outcomes of AKI and to analyze the factors associated with adverse renal outcomes. Materials and Methods: We retrospectively studied AKI patients stratified according to the Kidney Disease: Improving Global Outcomes (KDIGO) stage, regarding clinicodemographic data, renal replacement therapy (RRT), and 90-day outcomes. Those with preexisting CKD Stage 4 (defined by estimated glomerular filtration rate [eGFR] <30 mL/min/1.73 m2) and above, prior renal transplant (s), or acute glomerulonephritis were excluded. The primary outcome was a composite of de novo CKD (eGFR <60 mL/min/1.73 m2) or CKD progression (decline in eGFR category to any higher stage) in patients with baseline CKD at 90 days. The secondary outcome was a composite of de novo CKD, CKD progression, or death at 90 days. Results: Of the 358 patients, 52.5% had Stage 3 AKI. Eighty-eight patients (24.6%) had baseline CKD. Sepsis (51.4%) was the predominant etiology followed by nephrotoxins (42.5%). Renal replacement therapy (RRT) was required in 94 (26.3%) patients with hemodialysis being the most common modality. After excluding lost to follow-up, 66 patients (20.3%) had the primary outcome, and 195 patients (60%) had the secondary outcome. The 90-day mortality was observed in 39.7% of patients. AKI stage (P = 0.002), baseline CKD (P = 0.000) and RRT need (P = 0.005) were significantly associated with the primary outcome, while age >60 (P = 0.018), SOFA (Sequential Organ Failure Assessment) ≥9 (P = 0.000), hypoalbuminemia (P = 0.024), baseline CKD (P = 0.000) and RRT need (P = 0.001) were associated with the secondary outcome. Conclusion: Sepsis was the dominant precipitant of AKI and a major proportion had preventable etiology. AKI severity, baseline CKD status, and RRT need were found to predict the development or progression of CKD.

RESUMO

Introduction: Clinical use of tacrolimus has been challenging due to its narrow therapeutic index and highly variable pharmacokinetics. In this study, we compared patients who received body weight-based tacrolimus dosing pre-transplant (transplanted from 2016 to 2018) with those who received CYP3A5 genotype-based dosing (2018 to 2020). Methods: Eighty-two renal transplant recipients were non-randomly assigned to genotype-adapted or bodyweight-based tacrolimus dosing groups. The primary end point was to study the proportion of subjects who achieved the target tacrolimus C0 on post-op day 4. Secondary end points included clinical outcomes and safety. Results: The proportion of subjects who achieved the target tacrolimus C0 on postoperative days 4 and 10 were significantly higher in the adapted group, 53.6% and 47.5%, compared to 24.3% and 17% in controls, respectively (P = 0.01). Adapted group subjects achieved their first target tacrolimus C0 significantly earlier (4 days) compared to 25 days in controls (P = 0.01). The total number of tacrolimus dose modifications required in the first postop month were lower in the adapted group; 47 compared to 68 in the controls (P = 0.05). The proportion of subjects with sub-therapeutic tacrolimus exposure on postoperative day 4 was significantly higher in the controls, 56% versus 10% in the adapted group (P < 0.001). There were no significant differences between the groups in the rate of biopsy proven acute rejections, adverse events, and graft function at the end of 3 months follow up. Conclusion: Genotype-based tacrolimus dosing leads to more subjects achieving the target tacrolimus C0 earlier. However, there may be a higher risk of tacrolimus nephrotoxicity.

RESUMO

Background: t(8;21)(q22;q22) is the most frequent recurrent translocation in acute myeloid leukemia (AML) resulting in an in-frame fusion of RUNX1/RUNX1T1 that regulates various genes involved in the signaling pathways. This leukemogenic alteration is usually associated with a favorable clinical outcome. Variants of t(8;21) can be formed involving a third or fourth chromosome in ~3-4% of t(8;21)-AML. Due to the rarity of variant t(8;21), its clinicopathological features and prognostic significance are still unclear. Here we present three AML cases with cryptic rearrangements of chromosomes 8 and 21 without standard RUNX1/RUNX1T1. Materials and Methods: Conventional karyotyping and fluorescence in situ hybridization and/or spectral karyotyping of the pretreatment bone marrow aspirate of de novo AML patients were performed to delineate chromosomal abnormalities. Results: We identified three cases with novel variants of t(8;21); der(13)t(8;21;13), isodicentric derivative 8 with chromosome 21[,+idicder(8)(q11.1)t(8;21)(q22;q11.1)] and der(21)t(8;12;21)(q22;q?;q22). Conclusion: AML with t(8;21)(q22;q22);RUNX1-RUNX1T1 forms a distinct WHO subcategory and hence the identification of variants or unusual translocations associated with t(8;21) deserves more attention. Contribution to the variant/ unusual t(8;21) database will further refine the risk stratification and may help to significantly advance the current treatment regimen.

RESUMO

Enterococcus faecium is an emerging ESKAPE bacterium that is capable of causing severe public health complications in humans. There are currently no licensed treatments or vaccinations to combat the deadly pathogen. We aimed to design a potent and novel prophylactic chimeric vaccine against E. faecium through an immunoinformatics approach The antigenic Penicillin-binding protein 5 (PBP 5) protein was selected to identify B and T cell epitopes, followed by conservancy analysis, population coverage, physiochemical assessment, secondary and tertiary structural analysis. Using various immunoinformatics methods and tools, two linear B-cell epitopes, five CTL epitopes, and two HTL epitopes were finally selected for vaccine development. The constructed vaccine was determined to be highly immunogenic, cytokine-producing, antigenic, non-toxic, non-allergenic, and stable, as well as potentially effective against E. faecium. In addition, disulfide engineering, codon adaptation, and in silico cloning, were used to improve stability and expression efficiency in the host E. coli. Molecular docking and molecular dynamics simulations indicated that the structure of the vaccine is stable and has a high affinity for the TLR4 receptor. The immune simulation results revealed that both B and T cells had an increased response to the vaccination component. Conclusively, the in-depth in silico analysis suggests, the proposed vaccine to elicit a robust immune response against E. faecium infection and hence a promising target for further experimental trials.

RESUMO

BACKGROUND: The risk of severe coronavirus disease 2019 (COVID-19) varies significantly among persons of similar age and is higher in males. Age-independent, sex-biased differences in susceptibility to severe COVID-19 may be ascribable to deficits in a sexually dimorphic protective attribute that we termed immunologic resilience (IR). OBJECTIVE: We sought to examine whether deficits in IR that antedate or are induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection independently predict COVID-19 mortality. METHODS: IR levels were quantified with 2 novel metrics: immune health grades (IHG-I [best] to IHG-IV) to gauge CD8+ and CD4+ T-cell count equilibrium, and blood gene expression signatures. IR metrics were examined in a prospective COVID-19 cohort (n = 522); primary outcome was 30-day mortality. Associations of IR metrics with outcomes in non-COVID-19 cohorts (n = 13,461) provided the framework for linking pre-COVID-19 IR status to IR during COVID-19, as well as to COVID-19 outcomes. RESULTS: IHG-I, tracking high-grade equilibrium between CD8+ and CD4+ T-cell counts, was the most common grade (73%) among healthy adults, particularly in females. SARS-CoV-2 infection was associated with underrepresentation of IHG-I (21%) versus overrepresentation (77%) of IHG-II or IHG-IV, especially in males versus females (P < .01). Presentation with IHG-I was associated with 88% lower mortality, after controlling for age and sex; reduced risk of hospitalization and respiratory failure; lower plasma IL-6 levels; rapid clearance of nasopharyngeal SARS-CoV-2 burden; and gene expression signatures correlating with survival that signify immunocompetence and controlled inflammation. In non-COVID-19 cohorts, IR-preserving metrics were associated with resistance to progressive influenza or HIV infection, as well as lower 9-year mortality in the Framingham Heart Study, especially in females. CONCLUSIONS: Preservation of immunocompetence with controlled inflammation during antigenic challenges is a hallmark of IR and associates with longevity and AIDS resistance. Independent of age, a male-biased proclivity to degrade IR before and/or during SARS-CoV-2 infection predisposes to severe COVID-19.

RESUMO

Thalidomide causes teratogenic effects in several animal species and in humans. Accordingly, the World Health Organization banned thalidomide when mothers who took thalidomide during pregnancy delivered abnormal fetuses. After four decades, thalidomide underwent drug "re-purposing" since its antiangiogenic and immunomodulatory effects were therapeutic for multiple myeloma. There are no reports of thalidomide's effects on prokaryotes, but it showed teratogenic effects in Arabidopsis thaliana, an ancestor of the plant kingdom. This proof of concept study clearly shows that thalidomide caused a significant and reproducible decrease in germination rate, nitric oxide (NO) production, and chlorophyll content of fennel plantlets. Thalidomide also induced the formation of abnormal fennel plantlets with stunting, wrinkling, and curling of fennel shoots and leaves. Notably, quantitative analysis showed that thalidomide caused a 50% increase in the formation of abnormal fennel plantlets and that these negative effects of thalidomide showed a 2.50- to 4-fold decrease when fennel seeds were co-incubated with an NO donor (Spermine NoNoate) or a stable cGMP analog 8-bromo Guanosine 3',5'-cyclic monophosphate (8-Bromo-cGMP). This study is important because it confirms that thalidomide's negative effects on fennel seed germination and growth are mediated by attenuation of NO and disruption of NO signaling. This reproducible model of thalidomide-induced, NO-dependent damage in a plant system can be used to further investigate the molecular mechanisms of thalidomide action in plants. Importantly, this study establishes a link between the evolution of development of higher plants and mammals.

RESUMO

A 32-year-old habitual tobacco chewer was diagnosed with squamous cell carcinoma of the tongue. He was initiated on chemo-radiation therapy. After completing 23 cycles of radiation and four cycles of cisplatin-based chemotherapy, he presented with acute nephritic syndrome. Renal biopsy showed IgA nephropathy and acute tubular injury. With supportive care, renal function stabilised with a reduction in proteinuria. We wish to highlight the poorly understood association between mucosal malignancies and IgA nephropathy. It is also interesting to note the peculiar temporal profile of glomerular involvement in our patient, where the onset of the glomerulonephritis was after the initiation of chemo-radiotherapy. This is unlike what has been described earlier.

RESUMO

A 30-year-old woman with history of passage of stones since childhood presented with oliguria and pedal edema for 10 days. She had hypertension with a creatinine of 4.1 mg/dL. Evaluation showed presence of bilateral multiple renal calculi with features of chronicity of kidney disease. Metabolic work-up for nephrolithiasis turned out to be negative and eventually renal biopsy revealed features of chronic interstitial nephritis with greenish brown refractile crystals in the tubular lumen and interstitium. The possibility of dihydroxy adenine crystalline nephropathy was considered. Spectrophotometry of RBC lysates revealed decreased activity of Adenine phosphoribosyl-transferase enzyme. Gene amplification by PCR and sequential analysis identified a missense mutation in exon 3 region of APRT gene in the patient and her family members. This case report highlights the need to contemplate the diagnosis of DHA crystalline nephropathy in young patients with nephrolithiasis and the identification of a rare genetic mutation, which is being reported for the first time in India.

RESUMO

BACKGROUND: Cardiovascular Diseases (CVDs) such as stroke, high blood pressure, peripheral vascular disease, ischemic heart disease and acute myocardial infarction are some of the leading causes of death. To treat CVDs, commercially available thrombolytic agents are widely used. However, these thrombolytic agents have various side effects. Alternatively, fibrinolytic enzymes from bacterial sources are highly safe and have direct blood clot lytic activity. METHODS: A fibrinolytic enzyme producing bacterial strain, Bacillus flexus BF12, was isolated from a solar saltpan in Kanyakumari District, Tamilnadu, India. Enzyme production was improved by optimizing physical factors and nutritional factors. RESULTS: A novel fibrinolytic enzyme was isolated from a strain of the studied B. flexus BF12. Enzyme production was enhanced significantly by optimizing process parameters. The critical physical factors (pH and salinity) and influencing nutritional factors (carbon, nitrogen and ions) were optimized by one variable at a time approach, followed by the statistical method. The strain BF12 was highly active at alkaline pH (>7.0) and between 4 and 6% NaCl concentration. The nutrients such as fructose (carbon source), beef extract (nitrogen source) and CaCl2 significantly influenced enzyme production. Central composite design and response surface methodology improved 3.2-fold enzyme yield than unoptimized culture medium. Fibrinolytic protease was purified by ammonium sulphate precipitation, dialysis and gel filtration chromatography. DISCUSSION: The molecular weight of an enzyme was found to be 23 kDa. It was active at a broad temperature (40-60 °C) and pH (7.0-9.0) ranges. Enzyme activity was enhanced by Ca2+ and Co2+ ions. The purified protease retained 100% enzyme activity in the presence of ethanol and acetone. Acetonitrile, butanol, DMSO, methanol and chloroform showed enzyme activity of 63%, 92.5%, 94.7%, 92.3% and 90.4%, respectively. The purified enzyme degraded 100% of human blood clot. CONCLUSION: The Bacillus flexus BF12 fibrinolytic enzyme shows promising potentials in nutraceutical and food fortification applications. The application of fibrinolytic enzymes could prevent CVDs.

RESUMO

Patient living with chronic viral hepatitis in India faces the high cost of treatment and impoverishment. The present study is aimed to assess the cost of treatment and economic consequences among chronically infected viral hepatitis patients at a tertiary care hospital in Delhi. The descriptive cross-sectional study was undertaken during October 2016-January 2017. Three hundred and eighty-nine participants were interviewed through a schedule for variables and assessing both direct and indirect costs. Costs of hospital expenditure were extracted from records available with patients or databases of the hospital. The average outpatient expenditure and the inpatient costs were calculated. Direct nonmedical costs were also included. The analysis revealed the total cost of treatment ranged from Rs. 16,600/-to Rs. 1,709,000/-with a median of Rs. 193,500 per year. The cost of treatment increased with the severity of the disease. The cost of treatment led to impoverishment in 52.8% of families and imposed a substantial economic burden and consequences on the patients.

RESUMO

A 28-year-old male, 3 years post renal transplant with stable graft function, presented with vomiting for 2 days. He had graft dysfunction and graft biopsy done revealed acute cell - mediated rejection BANFF-IA. After receiving glucocorticoids for rejection, he developed severe enterocolitis and impending respiratory failure. Chest X-ray and computed tomography of the chest revealed miliary mottling. Evaluation showed presence of filariform larvae of Strongyloides stercoralis in the stool and sputum. A diagnosis of Strongyloides Hyperinfection Syndrome (SHS) was made. After a prolonged course of treatment with noninvasive ventilation, broad-spectrum antimicrobials, parenteral ivermectin and oral albendazole therapy, he eventually recovered. This case report is to highlight that Strongyloides Hyperinfection Syndrome should also be considered in the differential in any immunocompromised patient presenting with miliary mottling in imaging.

RESUMO

Despite several decades of intensive research and hard work in nephrology, a void exists in the availability of markers for identifying at-risk individuals, diagnosing diseases at incipient stage, and predicting treatment response. Most of the current widely available diagnostic tools such as creatinine, urine analysis, and imaging studies are quite insensitive such that about half of the kidney function is lost before perceivable changes are observed with these tests. In addition, these parameters are affected by factors other than renal, questioning their specificity. Renal biopsy, though specific, is quite expensive, risky, and invasive. The recent surge in the knowledge of small molecules in the tissue and body fluids, "metabolomics," thanks to the Human Metabolome Database created by the Human Metabolome Project, has opened a new avenue for better understanding the disease pathogenesis and, in parallel, to identify novel biomarkers and druggable targets. Kidney, by virtue of its metabolic machinery and also being a major handler of metabolites generated by other tissues, is very much amenable to the metabolomic approach of studying its various perturbations. The gut microbiome, characterized by the Human Microbiome Project, is one of the principal players in metabolomics. Changes in metabolite profile due to alterations in gut microbiome can occur either as a cause or consequence of renal diseases. Unmasking the renal-metabolome-microbiome link has a great potential to script a new era in the diagnosis and management of renal diseases.

RESUMO

We report a 49-year-old man with microscopic hematuria, subnephrotic proteinuria, and rapidly progressive renal failure. His biopsy had features of PhosphoLipase A2 Receptor (PLA2R) positive membranous nephropathy with circumferential cellular crescents. Further work-up revealed IgG antiGlomerular Basement Membrane (anti-GBM) antibody titer of 188 U/mL (normal <7 U/mL). A final diagnosis of membranous nephropathy with anti-GBM disease was made. These two distinct pathological entities can occur together resulting in significant morbidity and mortality unless diagnosed early and treatment initiated promptly. Outcomes have been poor, given the nonspecific presentation and delay in diagnosis.

RESUMO

AIM: To assess the impact of a pilot nurse-led paediatric oncology fast-track clinic (OFTC) for complications and side effects following chemotherapy within a paediatric tertiary hospital. METHODS: Prospective clinical data from the first 100 patients seen in the OFTC were compared with retrospective data of oncology patient presentations to the emergency department (ED) (over a 1-year period, n = 196) who would have been eligible for review in the OFTC. Parent and patient satisfaction of clinical care were also assessed via surveys pre- and post-OFTC implementation. RESULTS: Analysis which achieved statistical difference was a reduction in the number of blood tubes taken in OFTC (average 1.9 for those discharged from clinic, 2.9 for those admitted from clinic) in comparison to those seen in the ED (average 3.2) (p = 0.0027). The average number of interventions per patient seen in the ED were 2.1 (standard deviation 1.64) compared with 1.7 (standard deviation 1.55) interventions per patient seen in the OFTC, and who were not admitted following review. This result approached statistical significance with p = 0.0963. Other results which did not meet statistical significance included a reduction in treatment times, hospital admissions and medical oncology reviews. CONCLUSION: Our pilot study implementing an OFTC for the triage and assessment of chemotherapy-related complications has proven successful from an operational and consumer perspective. The clinic improved care by ensuring expedited review, more streamlined interventions, and less overall hospital admissions. The improvements in efficiency were also mirrored by increased parent and patient satisfaction.
