A CROSS-SECTIONAL STUDY OF THE ASSOCIATION BETWEEN THE 1-HOUR ORAL GLUCOSE TOLERANCE TEST AND THE METABOLIC SYNDROME IN A HIGH-RISK SAMPLE WITH IMPAIRED FASTING GLUCOSE.

Objective: The aim of this study was to evaluate the association between the 1-hour oral glucose tolerance test (OGTT) (≥155 mg/dL) and metabolic syndrome (MS) in a sample with previous impaired fasting glucose (IFG). Methods: Three hundred and twenty four Peruvian subjects with a history of IFG ≥100 mg/dL were selected for a cross-sectional study. They underwent a 75 g OGTT and were assigned to different groups according to the result. We evaluated the association between 1-hour OGTT and MS. Results: The mean age was 56.5 ± 12.6 years and 191 (61.5%) were female. During the OGTT, we found 28 (8.6%) subjects with diabetes, 74 (22.8%) with IGT, and 222 (68.5%) with a normal glucose tolerance test with a 2-hour glucose <140 mg/dL (NGT). In the NGT group, 124 (38.3%) had 1-hour glucose levels <155 mg/dL, while 98 (30.2%) had 1-hour glucose levels ≥155 mg/dL. Evaluating the association between the 1-hour value in the OGTT and MS, we found that subjects with a 1-hour glucose ≥155 mg/dL were more than twice as likely to have MS as those with a 1-hour glucose <155 mg/dL (odds ratio = 2.64, 95% confidence interval: 1.52 to 4.57). In addition, body mass index, fasting glycemia, triglycerides, and waist circumferences were significantly higher in subjects with 1-hour glucose levels ≥155 mg/dL compared to those with 1-hour glucose levels <155 mg/dL (P<.05). Conclusion: Among subjects with IFG, performing an OGTT was helpful to identify subjects with 1-hour glucose levels ≥155 mg/dL and NGT who were significantly more likely to have MS and a worse cardiometabolic risk profile. Abbreviations: AST = aspartate aminotransferase; BMI = body mass index; CI = confidence interval; IFG = impaired fasting glucose; IGT = impaired glucose tolerance; LDL = low-density lipoprotein; MS = metabolic syndrome; NGT = normal glucose tolerance; OGTT = oral glucose tolerance test; OR = odds ratio; T2DM = type 2 diabetes; TG = triglycerides.

The effect of diet on the physical and mental development of children: views of parents and teachers in four European countries.

Although the impact of diet on physical health is an important public health issue, less attention has been devoted to the relationship between nutrition and children's mental development. The views of parents and teachers about the extent to which diet affects physical and mental development of children were compared in four European countries. An online questionnaire (developed in English and translated) was circulated through a market research agency. Participants were parents or teachers of children aged 4-10 years without learning or behavioural issues. Questionnaires were returned by 1606 parents (401 in England, Germany and Hungary; 403 in Spain) and 403 teachers (100 in each country, except for 103 in Hungary). Teachers were older than parents (35·3 % v. 18·3 % over 45 years; P<0·001) and less likely to smoke (15·9 % v. 26·3 %, P<0·001). There was no difference between the proportions of parents and teachers who felt that a child's physical development depended very much/extremely (v. moderately/slightly/not at all) on diet (overall 79·8 %). Lower proportions of both groups thought that mental development was very much/extremely influenced by diet (67·4 %). In the regression modelling, believing that physical and mental performance was greatly influenced by diet was significantly and positively associated with living in Hungary, scoring higher on a measure of General Health Interest and (parents only) level of education attained. Differences existed among countries in most views. Lower levels of awareness of the importance of diet for brain development and cognition (compared with physical health outcomes) indicate the potential for educating consumers, especially parents with lower educational attainment.

Importance of mental performance in parental choice of food for children aged 4-10 years: a study in four European countries.

OBJECTIVE: Typically, attention focuses on how nutrition affects physical health. The present study investigated the importance that parents attach to the impact of diet on mental performance when choosing food for their child. DESIGN: Questionnaire. SETTING: Four European countries. SUBJECTS: Parents of children aged 4-10 years (n 1574): England (n 397), Germany (n 389), Hungary (n 398) and Spain (n 390). RESULTS: Most parents (80-85 %) considered the effect of food on four elements of mental performance (child's ability to learn, attention, behaviour, mood) to be moderately, very, extremely (v. slightly, not at all) important in food choices; over 90 % considered healthiness of food and making food appealing to their child important; 79·8 % cost; 76·8 % convenience. Belief that food affects mental performance was 57·4 % (ability to learn), 60·5 % (attention); less than 40 % of parents agreed they were aware which foods had an effect. Parents with lower general interest in healthy eating were less likely to consider the effect of food on mental performance elements as important. Respondents from Germany were more likely to rate mental performance as important (except behaviour); those in Hungary less likely. The most important influence on parents' decisions about feeding their child was their own experience, except Spain, where family/friends/health professionals were more important. CONCLUSIONS: Nutrition affects brain development and cognitive functioning. Low prioritisation of the effect of food on mental performance indicates potential for educating parents.

Developing Cultural Competence through the Introduction of Medical Spanish into the Veterinary Curriculum.

The AAVMC has prioritized diversity as one of its core values. Its DiVersity Matters initiative is helping veterinary medicine prepare for the changing demographics of the United States. One example of the changing demographics is the growing Hispanic population. In 2013, the Texas A&M University College of Veterinary Medicine & Biomedical Sciences responded to the needs of this growing sector by introducing medical Spanish into the core curriculum for Doctor of Veterinary Medicine (DVM) students. The medical Spanish course takes place over 5 weeks during the second year of the curriculum, and is composed of lectures and group learning. While this may seem like a very compressed time frame for language learning, our goal is to provide students with basic medical vocabulary and a limited number of useful phrases. In this paper, we outline the implementation of a medical Spanish course in our curriculum, including our pedagogical approaches to the curricular design of the course, and an explanation of how we executed these approaches. We also discuss the successes and challenges that we have encountered, as well as our future plans for the course. We hope that the successes and challenges that we have encountered can serve as a model for others who plan to introduce a foreign language into their curriculum as a component of cultural competency.

Adaptations of the endothelin system after exercise training in a porcine model of ischemic heart disease.

OBJECTIVE: To the test the hypothesis that exercise training would increase endothelin-mediated vasoconstriction in collateral-dependent arteries via enhanced contribution of ET(A). METHODS: An ameroid constrictor was surgically placed around the proximal LCX artery to induce gradual occlusion in Yucatan miniature swine. Eight weeks postoperatively, pigs were randomized into sedentary or exercise-training (treadmill; 5 days/week; 14 weeks) groups. Subsequently, arteries (~150 µm diameter) were isolated from collateral-dependent and nonoccluded myocardial regions and studied. RESULTS: Following exercise training, ET-1-mediated contraction was significantly enhanced in collateral-dependent arteries. Exercise training induced a disproportionate increase in the ET(A) contribution to the ET-1 contractile response in collateral-dependent arteries, with negligible contributions by ET(B). In collateral-dependent arteries of sedentary pigs, inhibition of ET(A) or ET(B) did not significantly alter ET-1 contractile responses in collateral-dependent arteries, suggesting compensation by the functionally active receptor. These adaptations occurred without significant changes in ET(A), ET(B), or ECE mRNA levels but with significant exercise-training-induced elevations in endothelin levels in both nonoccluded and collateral-dependent myocardial regions. CONCLUSIONS: Taken together, these data reveal differential adaptive responses in collateral-dependent arteries based upon physical activity level. ET(A) and ET(B) appear to compensate for one another to maintain contraction in sedentary pigs, whereas exercise-training favors enhanced contribution of ET(A).

Exercise training-induced adaptations in mediators of sustained endothelium-dependent coronary artery relaxation in a porcine model of ischemic heart disease.

OBJECTIVE: The aim of this study was to test the hypothesis that exercise training enhances sustained relaxation to persistent endothelium-dependent vasodilator exposure via increased nitric oxide contribution in small coronary arteries of control and ischemic hearts. METHODS: Yucatan swine were designated to a control group or a group in which an ameroid constrictor was placed around the proximal LCX. Subsequently, pigs from both groups were assigned to exercise (five days/week; 16 weeks) or SED regimens. Coronary arteries (~100-350 µm) were isolated from control pigs and from both nonoccluded and collateral-dependent regions of chronically-occluded hearts. RESULTS: In arteries from control pigs, training significantly enhanced relaxation responses to increasing concentrations of bradykinin (10(-10) -10(-7) M) and sustained relaxation to a single bradykinin concentration (30 nM), which were abolished by NOS inhibition. Training also significantly prolonged bradykinin-mediated relaxation in collateral-dependent arteries of occluded pigs, which was associated with more persistent increases in endothelial cellular Ca(2+) levels, and reversed with NOS inhibition. Protein levels for eNOS and p-eNOS-(Ser1179), but not caveolin-1, Hsp90, or Akt, were significantly increased with occlusion, independent of training state. CONCLUSIONS: Exercise training enhances sustained relaxation to endothelium-dependent agonist stimulation in small arteries of control and ischemic hearts by enhanced nitric oxide contribution and endothelial Ca(2+) responses.

Functional outcomes and quality of life in patients treated with laparoscopic total colectomy for colonic inertia.

PURPOSE: To assess the functional outcomes and quality of life in patients with laparoscopic total colectomy for slow-transit constipation (STC). METHODS: All patients undergoing laparoscopic colectomy with ileorectal anastomosis for colonic inertia at two referral centers were analyzed. Their preoperative, intraoperative and postoperative details were recorded with a one-year follow-up. Their quality of life was assessed using the SF-36 questionnaire. RESULTS: Between 2004 and 2007, 710 patients were evaluated. Eight female patients (1.1 %) fulfilled the criteria for STC without obstructive defecation syndrome. Their mean age was 38 years ± 15 (range from 22 to 62). The conversion rate was 12.5 %. The morbidity rate was 37.5 %, and mortality was nil. The preoperative abdominal pain was 6.6 ± 0.3 and had decreased to 3.6 ± 2.3 postoperatively (P = 0.008). At 1 year, the defecation frequency per week had increased from 0.84 ± 0.24 to 6.75 ± 3.4 (P = 0.001). Three patients developed nocturnal leakage (37.5 %). Eighty-eight percent of the patients recommend the procedure. All parameters of the SF-36 questionnaire had improved at the one-year follow-up examination. CONCLUSION: Laparoscopic colectomy for slow-transit constipation is safe and increased the number of evacuations per week. Although nocturnal leakage may occur, these patients experience improvements in their quality of life.

Prediabetes and Cardiometabolic Risk: The Need for Improved Diagnostic Strategies and Treatment to Prevent Diabetes and Cardiovascular Disease.

The progression from prediabetes to type-2 diabetes depends on multiple pathophysiological, clinical, and epidemiological factors that generally overlap. Both insulin resistance and decreased insulin secretion are considered to be the main causes. The diagnosis and approach to the prediabetic patient are heterogeneous. There is no agreement on the diagnostic criteria to identify prediabetic subjects or the approach to those with insufficient responses to treatment, with respect to regression to normal glycemic values or the prevention of complications. The stratification of prediabetic patients, considering the indicators of impaired fasting glucose, impaired glucose tolerance, or HbA1c, can help to identify the sub-phenotypes of subjects at risk for T2DM. However, considering other associated risk factors, such as impaired lipid profiles, or risk scores, such as the Finnish Diabetes Risk Score, may improve classification. Nevertheless, we still do not have enough information regarding cardiovascular risk reduction. The sub-phenotyping of subjects with prediabetes may provide an opportunity to improve the screening and management of cardiometabolic risk in subjects with prediabetes.

Difficult diagnosis in the clinical evaluation of a patient with squamous cell carcinoma of the sigmoid colon: a case report.

BACKGROUND: Squamous cell carcinoma (SCC) of the sigmoid colon is an exceedingly rare subtype of colorectal cancer (CRC) associated with chronic inflammatory conditions. Due to its variable clinical presentation ranging from subclinical to fully symptomatic and limited available information, it poses a diagnostic challenge. We aim to provide a review of the current literature and raise awareness about the importance of a thorough clinical analysis for an early diagnosis. CASE PRESENTATION: We describe the case of a 59-year-old Peruvian woman with a medical history of diverticular disease and irritable bowel syndrome. The patient presented with nonspecific symptoms such as abdominal discomfort, constipation, and bloating. Diagnostic tests and biopsy revealed a rare case of squamous cell carcinoma of the sigmoid colon. The patient underwent surgical resection and adjuvant chemotherapy. CONCLUSION: Despite the rarity of this type of cancer in the colon, the patient's clinical course highlights the importance of considering it as a potential diagnosis in patients with nonspecific symptoms and a history of gastrointestinal disorders. Surgical treatment followed by radiotherapy is the preferred management. Factors such as lack of postoperative complications and the stage of the neoplasia can augur a positive. PROGNOSIS: A prompt diagnosis is crucial, as detecting a neoplasia in its early stages can make surgery more effective.

Real-life use of cefiderocol for salvage therapy of severe infections due to carbapenem-resistant Gram-negative bacteria.

Treatment of infections caused by carbapenem-resistant Gram-negative bacteria (CR-GNB) is challenging and new active antibiotics are needed urgently. This study describes the efficacy and safety of cefiderocol in a retrospective series of 13 patients with severe CR-GNB infection and limited treatment options. Pseudomonas aeruginosa was the predominant CR-GNB (n=8), followed by Burkholderia cepacia (n=3), Sthenotrophomona maltophilia (n=1) and KPC-producing Klebsiella pneumoniae (n=1). The source of infection was nosocomial pneumonia in 92.3% of cases (12/13), of which 11 cases were ventilator-associated pneumonia. Five patients were lung transplant recipients (38.5%). The median duration of treatment was 10 days (range 6-21 days). No severe adverse effects required reducing the dose or interrupting the treatment. Clinical and microbiological cure were assessed 7 days after the end of treatment, and achieved in 84.6% (11/13) of patients. Crude mortality at day 28 was observed in 23.1% (3/13) of cases. Cefiderocol is a valid alternative for the treatment of susceptible CR-GNB infections in patients with limited therapeutic options.

A qualitative interview study on effects of diet on children's mental state and performance. Evaluation of perceptions, attitudes and beliefs of parents in four European countries.

Nutrition is one of the many factors that influence a child's cognitive development and performance. Understanding the relationship between nutrition and mental performance in children is important in terms of their attainment and productivity both in school and later life. Since parents are seen as nutritional gatekeepers for their children's diets, their views and beliefs are of crucial importance. The present study aims to qualitatively examine parents' perceptions of the relationship between diet and mental performance of children. The study was conducted with a total of 124 parents in four European countries using a semi-structured interview schedule. Parents speak of the effects of diet at two levels; the nature of the effects of diet and the characteristics of the foods responsible for these effects. Mental outcomes are related to diet, with the effects perceived to be associated with attention and concentration, often mediated by effects on children's mood and behaviour. Parents categorise foods as 'good' or 'bad' with positive effects related generally to a healthy balanced diet while negative effects are perceived to be associated with sugary and fatty foods. Understanding parental perceptions is important for many purposes including the targeting of dietary advice and prioritising of public health issues.

Laparoscopic Hartmann's reversal has better clinical outcomes compared to open surgery: An international multicenter cohort study involving 502 patients.

Background: Hartmann's procedure (HP) is used in surgical emergencies such as colonic perforation and colonic obstruction. "Temporary" colostomy performed during HP is not always reversed in part due to potential morbidity and mortality associated with reversal. There are several contributing factors for patients requiring a permanent colostomy following HP. Therefore, there is still some discussion about which technique to use. The aim of this study was to evaluate perioperative variables of patients undergoing Hartmann's reversal using a laparoscopic and open approach. Methods: The multicenter retrospective cohort study was done between January 2009 and December 2019 at 14 institutions globally. Patients who underwent Hartmann's reversal laparoscopic (LS) and open (OS) approaches were evaluated and compared. Sociodemographic, preoperative, intraoperative variables, and surgical outcomes were analyzed. The main outcomes evaluated were 30-day mortality, length of stay, complications, and postoperative outcomes. Results: Five hundred and two patients (264 in the LS and 238 in the OS group) were included. The most prevalent sex was male in 53.7%, the most common indication was complicated diverticular disease in 69.9%, and 85% were American Society of Anesthesiologist (ASA) II-III. Intraoperative complications were noted in 5.3% and 3.4% in the LS and OS groups, respectively. Small bowel injuries were the most common intraoperative injury in 8.3%, with a higher incidence in the OS group compared with the LS group (12.2% vs. 4.9%, p < 0.5). Inadvertent injuries were more common in the small bowel (3%) in the LS group. A total of 17.2% in the OS versus 13.3% in the LS group required intensive care unit (ICU) admission (p = 0.2). The most frequent postoperative complication was ileus (12.6% in OS vs. 9.8% in LS group, p = 0.4)). Reintervention was required mainly in the OS group (15.5% vs. 5.3% in LS group, p < 0.5); mortality rate was 1%. Conclusions: Laparoscopic Hartmann's reversal is safe and feasible, associated with superior clinical outcomes compared with open surgery.

Ca2+ sensitization and PKC contribute to exercise training-enhanced contractility in porcine collateral-dependent coronary arteries.

Exercise training enhances endothelium-dependent coronary vasodilatation, improving perfusion and contractile function of collateral-dependent myocardium. Paradoxically, studies from our laboratory have revealed increased Ca(2+)-dependent basal active tone in collateral-dependent arteries of exercise-trained pigs. In this study, we tested the hypothesis that exercise training enhances agonist-mediated contractile responses of collateral-dependent arteries by promoting Ca(2+) sensitization. Ameroid constrictors were surgically placed around the proximal left circumflex coronary (LCX) artery of female Yucatan miniature pigs. Eight weeks postoperatively, pigs were randomized into sedentary (pen confined) or exercise-training (treadmill run; 5 days/wk; 14 wk) groups. Arteries (∼150 µm luminal diameter) were isolated from the collateral-dependent and nonoccluded (left anterior descending artery supplied) myocardial regions, and measures of contractile tension or simultaneous tension and intracellular free Ca(2+) concentration levels (fura-2) were completed. Exercise training enhanced contractile responses to endothelin-1 in collateral-dependent compared with nonoccluded arteries, an effect that was more pronounced in the presence of nitric oxide synthase inhibition (N(ω)-nitro-l-arginine methyl ester; 100 µM). Contractile responses to endothelin-1 were not altered by coronary occlusion alone. Exercise training produced increased tension at comparable levels of intracellular free Ca(2+) concentration in collateral-dependent compared with nonoccluded arteries, indicative of exercise training-enhanced Ca(2+) sensitization. Inhibition of PKC (calphostin C; 1 µM), but not Rho-kinase (Y-27632, 10 µM; or hydroxyfasudil, 30 µM), abolished the training-enhanced endothelin-1-mediated contractile response. Exercise training also increased sensitivity to the PKC activator phorbol 12,13-dibutyrate in collateral-dependent compared with nonoccluded arteries. Taken together, these data reveal that exercise training enhances endothelin-1-mediated contractile responses in collateral-dependent coronary arteries likely via increased PKC-mediated Ca(2+) sensitization.

Combined Endoscopic-Robotic Resection of a Giant Polyp to Avoid Colorectal Resection.

Colorectal cancer prevention relies on effective screening through colonoscopy and polypectomy. Several techniques and methods have been described to manage complex colonic polyps such as the ones that are endoscopically unresectable. Across time, we have been able to perform less invasive techniques that include different types of colonic resections, ranging from partial thickness, full-thickness and, segmental colectomies, however, none has proven to be the treatment of choice for these lesions. The technique presented here is an attractive alternative to segmental colectomy using a robotic platform to perform a full-thickness resection.

Control of differential-drive mobile robots for soft object deformation.

The aim of this work is a control scheme implementation to deform a nonrigid object in which deformation dynamics are modeled by the finite element method. The deformation of a soft object is highly difficult to model because of its non-linearity, time-dependency, and material-response characteristics. Thus, the control implementation for Differential Drive Mobile Robots (DDMR) to deform an elastic object, is a challenge. The proposed steps to solve it are: Position-control designed over DDMR kinematics. Alignment-control applied for DDMRs orientation. The desired shape of the object is achieved using two contact points as the control nodes. A centralized vision algorithm was employed in each stage to obtain positions. To show the usefulness of the proposed scheme, numerical simulation, and real-time implementation were carried out.

Atypical hyperglycemia presentation suggests considering a diagnostic of other types of diabetes: first reported GCK-MODY in Perú.

BACKGROUND: Prevalence of maturity-onset diabetes of the young (MODY) is estimated between 1 and 2% of all diabetes cases. In Latin-America little information has been described about the frequency of the disease, perhaps due to limited access to genetic studies. CASE PRESENTATION: We present the case of a male patient with a history of two years of fatigue, mild hyperglycemia and intermittent polyuria, accompanied by a recent history of weight loss. He was diagnosed initially as type 2 diabetes, but in the follow-up as a patient with type 1 diabetes. He required relatively low doses of insulin and was evaluated in the endocrinology service at a hospital in Lima. The results of glucose, insulin and C-peptide in the oral glucose tolerance test (OGTT) performed were not consistent with a type 1 diabetes. Moreover, the age of the patient and the clinical characteristics did not strongly suggest a diagnosis of type 2 diabetes either. These clinical features had prompted us to carry out the genetic study. The genetic test performed with a genetic MODY panel through a massive sequencing. Heterozygous pathogenic for a variant in GCK gene was found (c.629 T > C, p.Met210Thr.). His parents were negative for this variant after performed the genetic test. CONCLUSIONS: This is the first case of MODY for a pathogenic variant in the GCK gene reported in Perú. The genetic evaluation of a clinical suspicion of MODY is important to confirm the diagnosis and establish an adequate treatment in patients.

Correction to: Atypical hyperglycemia presentation suggests considering a diagnostic of other types of diabetes: first reported GCK-MODY in Perú.

Polymerase Chain Reaction Versus Blood Culture to Detect Candida Species in High-Risk Patients with Suspected Invasive Candidiasis: The MICAFEM Study.

INTRODUCTION: We evaluated the diagnostic reliability of serum polymerase chain reaction (PCR) versus blood culture, abdominal fluid or both (composite measure) in patients receiving empirical antifungal treatment for suspected invasive candidiasis. METHODS: This observational, prospective, non-interventional, multicentre study in Spain enrolled 176 critically ill patients admitted to the intensive care unit. Separate blood samples for culture and serum PCR were taken before the start of antifungal therapy. Patient assessment was performed according to each site's usual clinical practice. The primary end point was concordance between serum PCR and blood culture. Secondary end points were concordance between serum PCR and a positive abdominal fluid sample or the composite measure. Quality indices included sensitivity, specificity, positive/negative predictive values (PPV/NPV) and kappa indices. RESULTS: Among 175 evaluable patients, rates of Candida detection were similar for serum PCR (n = 16/175, 9.1%) versus blood culture (n = 14/175, 8.0%). Quality indices for serum PCR relative to blood culture were: sensitivity 21.4%; specificity 91.9%; PPV 18.8%; NPV 93.1%; kappa index 0.125. Thirty-two abdominal fluid samples were positive. Quality indices for serum PCR versus abdominal fluid were: sensitivity 31.3%; specificity 83.0%; PPV 15.6%; NPV 92.3%; kappa index 0.100. Quality indices for serum PCR versus the composite measure were: sensitivity 15.8%; specificity 92.7%; PPV 37.5%; NPV 79.9%; kappa index 0.107. CONCLUSION: The sensitivity of serum PCR for Candida detection was low and the rate of concordance was low between serum PCR and the other diagnostic techniques used to identify Candida infections. Hospital-based diagnostic tests need optimising to improve outcomes in patients with suspected invasive candidiasis. FUNDING: Astellas Pharma Inc.

Prognosis of urinary tract infection caused by KPC-producing Klebsiella pneumoniae: The impact of inappropriate empirical treatment.

INTRODUCTION: There is scarce information on the prognosis of urinary tract infections (UTI) caused by KPC carbapenemase-producing Klebsiella pneumoniae (KPC-Kp). OBJETIVE: To investigate the association between KPC-Kp aetiology and clinical failure and all cause mortality and to explore the impact of inappropriate empirical treatment. MATERIAL AND METHODS: This is a retrospective observational study of hospitalized patients with UTI due to K. pneumoniae. We explored clinical failure at day 21 and 30-day all-cause mortality using different models of adjusted analysis. RESULTS: We analyzed 142 episodes of UTI; 46 episodes (32.4%) were due to KPC-Kp and 96 episodes (67.6%) were due to non-KPC-Kp strains (62 wild type and 34 EBSL producer). Clinical failure was more frequent in the KPC-Kp group (41.3% vs. 15.6%, p = 0.001). KPC-Kp aetiology and inappropriate empirical therapy were associated in the non-adjusted analysis with clinical failure. When analysed in separate adjusted models, both were found to be associated; inappropriate empirical treatment (OR 2.51; 95% CI, 1.03-6.12; p = 0.04) and KPC-Kp (OR 2.73; 95% CI, 1.03-7.22; p = 0.04) were associated with increased risk of failure. All-cause 30-day mortality was higher in patients with KPC-Kp UTI (39.1% vs. 15.6%, p = 0.002). Bacteraemia was more frequent in patients with KPC-Kp etiology (23.9% vs. 10.4%; p = 0.034). In both cases, the association was not confirmed in the adjusted analysis. CONCLUSION: KPC-Kp UTI is associated with higher clinical failure and may be due to an increase in inappropriate empirical treatment.
