RESUMEN

Triple negative breast cancers (TNBC) are clinically heterogeneous but mostly aggressive malignancies devoid of expression of the estrogen, progesterone, and HER2 (ERBB2 or NEU) receptors. It accounts for 15-20% of all cases. Altered epigenetic regulation including DNA hypermethylation by DNA methyltransferase 1 (DNMT1) has been implicated as one of the causes of TNBC tumorigenesis. The antitumor effect of DNMT1 has also been explored in TNBC that currently lacks targeted therapies. However, the actual treatment for TNBC is yet to be discovered. This study is attributed to the identification of novel drug targets against TNBC. A comprehensive docking and simulation analysis was performed to optimize promising new compounds by estimating their binding affinity to the target protein. Molecular dynamics simulation of 500 ns well complemented the binding affinity of the compound and revealed strong stability of predicted compounds at the docked site. Calculation of binding free energies using MMPBSA and MMGBSA validated the strong binding affinity between compound and binding pockets of DNMT1. In a nutshell, our study uncovered that Beta-Mangostin, Gancaonin Z, 5-hydroxysophoranone, Sophoraflavanone L, and Dorsmanin H showed maximum binding affinity with the active sites of DNMT1. Furthermore, all of these compounds depict maximum drug-like properties. Therefore, the proposed compounds can be a potential candidate for patients with TNBC, but, experimental validation is needed to ensure their safety.Communicated by Ramaswamy H. Sarma.

RESUMEN

What is the effect of our gut microbial flora on brain? Does the gut microbiome have any role in the causation of psychiatric and neurodegenerative diseases? Does the effect of gut microbiota traverse the gut-brain axis? Questions like these have captured the interest and imagination of the scientific community for quite some time now. Research in the quest for answers to these questions, to unravel the potential role of the microbiota inhabiting the gut in controlling brain functions, has progressed manifold over the last two decades. Although the possibility of microbiome as a key susceptibility factor for neurological disorders viz. Parkinson's disease, Alzheimer's disease, multiple sclerosis, and autism spectrum disorder has bolstered by an increase in the clinical and preclinical evidence, the field is still in its infancy. Given the fact that the diversity of the gut microbiota is affected by various factors including the diet and exercise, the interpretation of such data becomes all the more difficult. Also, such studies have been mostly conducted on animal models, so there is a need for randomized controlled trials in human subjects, corroborated by longitudinal studies, to establish if modulating the gut microbiota can unravel novel therapeutic interventions. Exploring the genomic, metagenomic and metabolomic data from clinical subjects with psychiatric and neurological diseases can prove to be a helpful guide in individual treatment selection.

RESUMEN

BACKGROUND/OBJECTIVES: Sarcopenia in pancreatic cancer may increase the risk of chemotherapy-related toxicity and post-operative morbidity. This systematic review and meta-analysis aimed to quantify the prevalence of sarcopenia in early stage pancreatic cancer. METHODS: Relevant studies were identified using Ovid Medline and Elsevier Embase. Pooled estimates of prevalence rates (percentages) and corresponding 95% confidence interval (CI) were computed using a random-effects model to allow for heterogeneity between studies. RESULTS: The majority of the 33 studies (n = 5,593 patients) included in this meta-analysis utilized computed tomography (CT)-derived measures for body composition assessment in patients undergoing pancreatic resection. Reported prevalence of sarcopenia varied between 14 and 74%, and the pooled prevalence was 39% (95% CI: 38-40%) Heterogeneity was considerable, however, (I2 = 93%) and did not improve significantly when controlling for assessment method, and use of pre-defined cut-offs for sarcopenia, limiting potential to evaluate the true impact of sarcopenia. CONCLUSION: The ready availability of sequential CT offers a valuable opportunity for body composition assessment, but the quality of assessment and interpretation must improve before the impact of body composition on treatment-related outcomes and survival can be assessed. We suggest recommendations for the assessment of body composition for the design of future studies.

RESUMEN

BACKGROUND: Laparoscopic cholecystectomy has become the standard surgical approach in the treatment of cholelithiasis. Diverse surgical techniques and different imaging modalities have been described to evaluate the biliary anatomy and prevent or early detect bile duct injuries. X-ray intraoperative cholangiography (IOC) and near infrared indocyanine green fluorescent cholangiography (NIR-ICG) are safe and feasible techniques to assess biliary anatomy. The aim of this systematic review will be to evaluate if NIR-ICG can visualize extrahepatic biliary anatomy more efficiently and safer than IOC in minimally invasive cholecystectomy for gallstone disease. METHODS: Literature search will be performed via MEDLINE (PubMed), Embase, Scopus, the Cochrane Central Register of Controlled Trials, and Web of Science Core Collection from 2009 to present. All randomized controlled clinical trials and prospective non-randomized controlled trials which report on comparison of NIR-ICG versus IOC will be included. All patients over 18 years old who require elective or urgent minimally invasive cholecystectomy (undergoing NIR-ICG during this procedure) due to gallstone disease both acute and chronic will be included. Since BDI has a low incidence, the primary outcome will be the ability to visualize extrahepatic biliary anatomy and the time to obtain relevant images of these structures. Two researchers will individually screen the identified records, according to a list of inclusion and exclusion criteria. Bias of the studies will be evaluated with the Newcastle-Ottawa score for non-randomized studies and with The Cochrane Risk of Bias Tool for randomized controlled trials. Quality of evidence for all outcomes will be determined with the GRADE system. The data will be registered in a predesigned database. If selected studies are sufficiently homogeneous, we will perform a meta-analysis of reported results. In the event of a substantial heterogeneity, a narrative synthesis will be provided. Subgroup analysis will be used to investigate possible sources of heterogeneity. DISCUSSION: Understanding the benefits of this technique is critical to ensuring policymakers can make informed decisions as to where preventive efforts should be focused regarding specific imaging techniques. If ICG is proven to be faster and non-invasive, its routine use could be encouraged. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42020177991 .

RESUMEN

In the present study, the efficiency of four different strains of Pseudomonas aeruginosa and their biosurfactants in the bioremediation process were investigated. The strains were found to be capable of metabolizing a wide range of hydrocarbons (HCs) with preference for high molecular weight aliphatic (ALP) over aromatic (ARO) compounds. After treating with individual bacteria and 11 different consortia, the residual crude oils were quantified and qualitatively analyzed. The bacterial strains degraded ALP, ARO, and nitrogen, sulphur, oxygen (NSO) containing fractions of the crude oil by 73-67.5, 31.8-12.3 and 14.7-7.3%, respectively. Additionally, the viscosity of the residual crude oil reduced from 48.7 to 34.6-39 mPa s. Further, consortium designated as 7 and 11 improved the degradation of ALP, ARO, and NSO HCs portions by 80.4-78.6, 42.7-42.4 and 21.6-19.2%, respectively. Moreover, addition of biosurfactant further increased the degradation performance of consortia by 81.6-80.7, 43.8-42.6 and 22.5-20.7%, respectively. Gas chromatographic analysis confirmed the ability of the individual strains and their consortium to degrade various fractions of crude oil. Experiments with biosurfactants revealed that polyaromatic hydrocarbons (PAHs) are more soluble in the presence of biosurfactants. Phenanthrene had the highest solubility among the tested PAHs, which further increased as biosurfactant doses raised above their respective critical micelle concentrations (CMC). Furthermore, biosurfactants were able to recover 73.5-63.4% of residual oil from the sludge within their respective CMCs. Hence, selected surfactant-producing bacteria and their consortium could be useful in developing a greener and eco-sustainable way for removing crude oil pollutants from soil.

RESUMEN

BACKGROUND: A progressive reduction in the secretion of pancreatic enzymes in patients with chronic pancreatitis (CP) results in malabsorption and ultimate malnutrition. However, the pathogenesis of malnutrition is multifactorial and other factors such as chronic inflammation, alcohol excess and poor dietary intake all contribute. Patients may restrict their dietary intake due to poor appetite or to avoid gastrointestinal symptoms and abdominal pain. Whilst up to half of patients with chronic pancreatitis are reportedly malnourished, the dietary intake of patients with CP is relatively understudied and has not been systematically reviewed to date. AIM: To perform a systematic review and meta-analysis of the dietary intakes of patients with CP compared to healthy controls, and to compare the dietary intake of patients with alcohol-related CP and non-alcohol-related CP. METHODS: A systematic literature search was performed using EMBASE, MEDLINE, and Cochrane review on studies published between 1946 and August 30th, 2019. Adult subjects with a diagnosis of CP who had undergone dietary assessment were included in the systematic review (qualitative analysis). Studies on patients with other pancreatic diseases or who had undergone pancreatic surgery were not included. Studies comparing the dietary intake of patients with CP to that of healthy controls were included in the meta-analysis (quantitative analysis). Meta-analysis was performed using Review Manager 5.3. Newcastle Ottawa Scale (NOS) was used to assess quality of studies. RESULTS: Of 6715 studies retrieved in the search, 23 were eligible for qualitative analysis while 12 were eligible for quantitative analysis. In the meta-analysis, the total energy (calorie) intake of patients with CP was similar to that of healthy controls [mean difference (MD): 171.3; 95% confidence interval (CI): -226.01, 568.5; P = 0.4], however patients with CP consumed significantly fewer non-alcohol calories than controls [MD: -694.1; 95%CI: -1256.1, (-132.1); P = 0.02]. CP patients consumed more protein, but carbohydrate and fat intakes did not differ significantly. Those with alcohol-related CP consumed more mean (standard deviation) calories than CP patients with a non-alcohol aetiology [2642 (1090) kcal and 1372 (394) kcal, respectively, P = 0.046], as well as more protein, fat, but not carbohydrate. CONCLUSION: Although patients with CP had similar calorie intake to controls, studies that analysed the contribution of alcohol to energy intake showed that patients with CP consumed fewer non-alcohol calories than healthy controls. A high calorie intake, made up to a large degree by alcohol, may in part contribute to poor nutritional status in CP.

RESUMEN

INTRODUCTION: Chronic pancreatitis (CP) is characterised by pain, functional deficits, nutritional and mechanical complications. Frequently managed in out-patient settings, the clinical course is unpredictable and requires multi-disciplinary care. There remains substantial variation in management. In contrast to acute pancreatitis, there are no globally accepted classification or severity scores to predict the disease course or compare interventions. We conducted a systematic review to determine the scope and clinical use of existing scoring systems. METHODS: A systematic search was developed with a medical librarian using the Embase, Medline and Cochrane databases. Original articles and conference abstracts describing an original or modified classification or scoring system in CP that stratified patients into clinical and/or severity categories were included. To assess clinical application/validation, studies using all or part of a score as a stratification tool to measure another parameter or outcome were selected. Studies reporting on diagnosis or aetiology only were excluded. Four authors performed the search in independent pairs and conflicts were resolved by a fifth author using CovidenceTM systematic review software. RESULTS: Following screening 6,652 titles and 235 full-text reviews, 48 papers were analysed. Eleven described original scores and 6 described modifications of published scores. Many were comprehensive but limited in capturing the full spectrum of disease. In 31 studies, a score was used to categorise patients to compare or correlate various outcome measures. Exocrine and endocrine dysfunction and pain were included in 6, 5, and 4 scoring systems, respectively. No score included other nutrition parameters, such as bone health, malnutrition, or nutrient deficiency. Only one score has been objectively validated prospectively and independently for monitoring clinical progression and prognosis, but this had been applied to an in-patient population. CONCLUSION: Available systems and scores do not reflect recent advances and guidelines in CP and are not commonly used. A practical clinical classification and scoring system, validated prospectively for prognostication would be useful for the meaningful analysis in observational and interventional studies in CP.

RESUMEN

We present a case of an unexpected cause of bowel ischemia in an intensive care unit patient with herpes simplex virus encephalitis who required an operation. A 79-year-old lady was being worked up and treated for encephalitis with antibiotics and an antiviral. On Day 13, she developed abdominal pain, and an ultrasound showed cholelithiasis but no cholecystitis; thus conservative treatment was advocated. By Day 18, pain localized to the right iliac fossa, and she had an emergency laparotomy that showed bowel ischemia and perforation of the caecum with the cause being a terminal ileal adhesional band. An extended right hemicolectomy and ileostomy was performed. Patients with significant comorbidities who are intensive care unit-dependent may still have unexpected clinical challenges. We advocate an increased clinical vigilance in this cohort for unexpected life-threatening presentations such as bowel ischemia and more specifically the cause of the bowel ischemia.

RESUMEN

AIMS: Evaluation of the role and impact of introducing a dedicated coloproctology procedure clinic in tertiary referral colorectal unit. METHODS: A retrospective analysis of 126 consecutive patients managed in the coloproctology clinic between March2015 and September 2016 was carried out. All patients were preselected for attendance based on symptom-based protocol. RESULTS: Based on the information available in GP referrals, 126 patients with bleeding per rectum with low risk of cancer were re-triaged from the general outpatient to dedicated coloproctology procedure clinic. Those patients accounted for 14% of waiting list. The average waiting time to attend clinic was 27 months from referral to undergoing definitive procedure. A proctoscopy or/and rigid sigmoidoscopy was performed in patients. Seventy-nine (89.7%) patients were completely managed and discharged after attending their first visit. Sixty-seven (76%) patients had 2nd- or 3rd-degree haemorrhoids and were treated with rubber band ligation (RBL) or phenol injection in outpatient setting. Two patients had an anal fissure and were managed conservatively with medication. After clinic, follow-up was through telephone clinic. This avoids attendance physically in the hospital. Symptoms persisted in nine patients and were subsequently scheduled for colonoscopy, three had benign polyps. With the introduction of the procedure clinic, the waiting time from referral to treatment was reduced from 27 to 6 months (p < 0.05). CONCLUSIONS: Establishing a dedicated "Coloproctology procedure clinic" is an effective strategy in reducing number of hospital visits per patient and hospital waiting list. This innovative clinic reduces utilisation of precious endoscopy unit resources. This ultimately will improve endoscopy efficiency.

RESUMEN

BACKGROUND & AIMS: Laparoscopic anti-reflux surgery (LARS) aims to provide relief from gastroesophageal reflux disease (GORD). With increase in the prevalence of obesity, there is a concurrent increase in obese patients requiring LARS. In addition to being a more technically difficult procedure, there is conflicting evidence regarding the effectiveness of LARS in obese patients. We performed a systematic review and meta-analysis to compare the outcomes of LARS in obese versus non-obese patients. METHODS: Articles on the effects of obesity on LARS were identified from Ovid Medline, EMBASE and the Cochrane Library databases up to 30th of November 2016. Two independent searches were conducted. Data were extracted independently by two researchers. The primary outcome was recurrence, whilst the secondary outcome was operative time. Pooled data were statistically analysed using forest and funnel plots. RESULTS: Twelve studies (3346 patients) met the inclusion criteria, with 923 patients in the obese group and 2423 patients in the non-obese group. Based on a random effects model, there was a risk ratio of 1.36 (95% CI 1.08-1.72, p = 0.009), if studies reporting recurrence objectively are analysed risk ratio of 1.53 (95% CI 1.01-2.32, p = 0.05) showing 53% increased risk of recurrence for obese patients. Using a random effects model, the difference in operative time was 13.94 min (95% confidence interval (CI) 9.33-18.55, p < 0.0001), showing an increased operative time for obese patients. CONCLUSION: A meta-analysis of 12 studies showed that there was greater recurrence of GORD symptoms and longer operative time relating to LARS in obese patients compared to non-obese patients.

RESUMEN

BACKGROUND: Small intestinal bacterial overgrowth (SIBO) is a condition characterised by symptoms similar to pancreatic exocrine insufficiency (PEI) in chronic pancreatitis patients. SIBO is thought to complicate chronic pancreatitis in up to 92% of cases; however, studies are heterogeneous and protocols non-standardised. SIBO may be determined by measuring lung air-expiration of either hydrogen or methane which are by-products of small bowel bacterial fermentation of intraluminal substrates such as carbohydrates. We evaluated the prevalence of SIBO among a defined cohort of non-surgical chronic pancreatitics with mild to severe PEI compared with matched healthy controls. METHODS: Thirty-five patients and 31 age-, gender- and smoking status-matched healthy controls were evaluated for SIBO by means of a fasting glucose hydrogen breath test (GHBT). The relationship between SIBO and clinical symptoms in chronic pancreatitis was evaluated. RESULTS: SIBO was present in 15% of chronic pancreatitis patients, while no healthy controls tested positive (P = 0.029). SIBO was more prevalent in those taking pancreatic enzyme replacement therapy (PERT) (P = 0.016), with proton pump inhibitor use (PPI) (P = 0.022) and in those with alcohol aetiology (P = 0.023). Patients with concurrent diabetes were more often SIBO-positive and this was statistically significant (P = 0.009). There were no statistically significant differences in reported symptoms between patients with and without SIBO, with the exception of 'weight loss', with patients reporting weight loss more likely to have SIBO (P = 0.047). CONCLUSION: The prevalence of SIBO in this study was almost 15% and consistent with other studies of SIBO in non-surgical chronic pancreatitis patients. These data support the testing of patients with clinically-relevant PEI unresolved by adequate doses of PERT, particularly in those patients with concurrent diabetes. SIBO can be easily diagnosed therefore allowing more specific and more targeted symptom treatment.

RESUMEN

INTRODUCTION: With high incidence of haemorrhoidal disease and significant complication rates of traditional haemorrhoidectomy procedures, transanal haemorrhoidal artery ligation and mucopexy (THD) emerges as a minimally invasive procedure with superior results. However, it is crucial that effectiveness of results and patient satisfaction be gauged based on post-operative experience, symptomology and recurrence. AIM: Our aim is to provide a long-term analysis of efficacy and patient's satisfaction for the procedure, for the largest patient population, in correlation to presenting symptoms and degree of haemorrhoids. METHOD: A prospective study was conducted for all the patients (324) that underwent THD between 2011 and 2016 in Naas General Hospital. The assessment was done for postoperative complications, symptoms pre- and postoperatively and patients' satisfaction rating. Clinical follow-up was done after 6 weeks and long-term follow-up by standardized questionnaire filled by telephonic clinic. RESULTS: Of the 324 patients who underwent surgery, 256 (79.0%) participated in the study. There were 119 (46.5%) males and 137 (53.5%) females. The average age of patients was 48.40 years (17-82). Two hundred and fifteen (84.0%) patients had no recurrence. Forty-one (16.0%) had recurrence requiring further treatment. There was statistically significant higher recurrence in patients with grade 3 and 4 haemorrhoids and per-rectal bleeding (p < 0.05) while there was no statistically significant recurrence for age, gender, sedentary lifestyle and constipation/pruritus. Two hundred and twenty-four (87.5%) patients were completely satisfied from the procedure and highly recommend the procedure. CONCLUSION: THD is a comparably pain-free procedure with improved results that prides in higher long-term satisfaction, minimal recurrence and fewer complications, in comparison to other surgical modalities.

RESUMEN

INTRODUCTION: Percutaneous Suprapubic urinary bladder catheterisation (SPC) is a common procedure performed in cases of urinary retention where attempt to pass urethral catheter has failed. However, the procedure requires meticulous precision, vigilance and sound knowledge of anatomy, to avoid grave complications. We are reporting a very rare complication of Suprapubic catheterisation that is small bowel obstruction. Our case is first Irish and 10th global case of small bowel obstruction secondary to SPC. CASE PRESENTATION: Aim of this study was to report this rare complication of the SPC in our patient who was 88 years old retired farmer presenting to emergency department with small bowel obstruction. In our case after clinical examination diagnosis was made with CT scan. Laparoscopy done and found that SPC passed through mesentery before entering bladder and was released laparoscopically. We also searched the literature to find similar reported cases to extract useful information from these cases and use this information to draw conclusions and make recommendations to avoid injuries in the future. Database search conducted in March 2017 on the bibliographic databases Ovid MEDLINE (1946 to November 2016) and EMBASE (1980 to November 2016) along with additional reference searching revealed only 9 reported cases of small bowel obstruction secondary to SPC. CONCLUSIONS: From the extensive literature search we found that there are only nine cases reported so far globally, and our case is first Irish and tenth international case of bowel obstruction secondary to SPC. Significantly distended bladder, use of ultrasound and extra precaution in elderly patients can reduce the risk of damage to bowel.

RESUMEN

BACKGROUND: Several studies have suggested a link between microbiota imbalance and some gastrointestinal, inflammatory and neoplastic diseases. However, the role in pancreatic diseases remain unclear. To evaluate the available evidence for pancreatic diseases, we undertook a systematic review. METHODS: OVID Medline (1946-2017), EMBASE (1980-2017) and the Cochrane Central Register of Controlled Trials (CENTRAL Issue 3, 2017) were searched for studies on microbiota in pancreatic disease. We also searched the reference lists of retrieved papers, and conference proceedings. We excluded animal studies, reviews, and case reports. RESULTS: A total of 2833 articles were retrieved. After screening and applying the exclusion criteria, 10 studies were included. Three studies showed lower levels of Bifidobacterium or Lactobacillus and higher levels of Enterobacteriaceae in chronic pancreatitis. Two of these studies were uncontrolled, and the third (controlled) study which compared patients with endocrine and exocrine insufficiency, reported that Bacteroidetes levels were lower in those patients without diabetes, while Bifidobacteria levels were higher in those without exocrine insufficiency. Only one study investigated acute pancreatitis, showing higher levels of Enterococcus and lower levels of Bifidobacterium versus healthy participants. There was an overall association between pancreatic cancer and lower levels of Neisseria elongate, Streptococcus mitis and higher levels of Porphyromonas gingivalis and Granulicatella adiacens. CONCLUSIONS: Current evidence suggests a possible link between microbiota imbalance and pancreatic cancer. Regarding acute and chronic pancreatitis, data are scarce, dysbiosis appears to be present in both conditions. However, further investigation is required to confirm these findings and to explore therapeutic possibilities.

RESUMEN

A series of previously conducted experiments pertaining to various chemicals and drugs uncover a natural linkage between the molecular structures and the bio-medical and pharmacological characteristics. The forgotten topological index computed for the molecular structures of various chemical compounds and drugs has proven significant in medical and pharmaceutical fields by predicting biological features of new chemical compounds and drugs. A topological index can be considered as the transformation of chemical structure into a real number. Dendrimers are highly-branched star-shaped macromolecules with nanometer-scale dimensions. Dendrimers are defined by three components: a central core, an interior dendritic structure (the branches), and an exterior surface with functional surface groups. In this paper, we determine forgotten topological indices of poly(propyl) ether imine, porphyrin, and zinc-porphyrin dendrimers.

RESUMEN

OBJECTIVE: To investigate trends in acute public hospital patient discharges in Ireland, to analyse hospital discharge activity for geographical variations, aetiological differences, and to estimate a national prevalence for chronic pancreatitis. METHOD: We performed a nationwide retrospective study of all in-patient discharges from acute public hospitals in Ireland, participating in the Hospital In-Patient Enquiry (HIPE) reporting system. We searched for International Classification of Disease, Tenth Revision, Australian Modification (ICD-10-AM) codes K86.0 alcohol-induced chronic pancreatitis, and K86.1 other chronic pancreatitis, and data were extracted for the years 2009-2013. RESULTS: There were 4098 emergency admissions for any aetiology chronic pancreatitis during the 5 year study period. Total discharges ranged from 753 in 2009 to 999 in 2013. Total patients ranged from 530 in 2009 to 601 in 2013. Prevalence of chronic pancreatitis is estimated at 11.6 per 100,000 to 13.0 per 100,000 over the five years. 'Other aetiology chronic pancreatitis' discharges were almost double that of 'alcohol chronic pancreatitis'. We found notable geographical variation in hospital discharge activity for chronic pancreatitis. CONCLUSIONS: We report a prevalence which is similar to those worldwide studies who adopted a similar methodology utilising exact counts of patients. Our data are an underestimated as they are based on in-patient discharges only, excluding those attending primary care, outpatient or emergency room visits without admission. Despite studying this disease in a population with high per capita alcohol consumption, we report almost twice as many discharges for non-alcohol aetiology chronic pancreatitis.

RESUMEN

This study is to probe the pattern of antibiotic resistance against aminoglycosides and its mechanism in E. coli obtained from patients from Chennai, India. Isolation and identification of pathogens were done on MacConkey agar. Antimicrobial sensitivity testing was done by disc diffusion test. The identification of genes encoding aminoglycoside modifying enzymes was done by Polymerase Chain Reaction (PCR). Out of 98 isolates, 71 (72.45%) isolates were identified as E. coli and the remaining 27 (27.55%) as other bacteria. Disc diffusion method results showed a resistance level of 72.15% for streptomycin, 73.4% for gentamicin, 63.26% for neomycin, 57.14% for tobramycin, 47.9% for netilmicin, and 8.16% for amikacin in E. coli. PCR screening showed the presence of four genes, namely, rrs, aacC2, aacA-aphD, and aphA3, in their plasmid DNA. The results point towards the novel mechanism of drug resistance in E. coli from UTI patients in India as they confirm the presence of genes encoding enzymes that cause resistance to aminoglycoside drugs. This could be an alarm for drug prescription to UTI patients.
