Acute appendicitis remains a common reason for hospital admission. Reports have suggested a reduction in patients attending emergency departments during the acute phase of the SARSCoV- 2 pandemic. Moreover, a global surge in conservative management of acute appendicitis has recently been registered by the Appy Study of the Association of Italian Surgeons in Europe (ACIE)1. This is a treatment option that has been known for some years, although quite seldom used before the pandemic2–4. As most countries are experiencing new waves of the pandemic, the attitude of surgeons towards SARS-CoV-2 screening policies and personal protective equipment (PPE) used during the management of patients with acute appendicitis need to be established. According to a subanalysis of the ACIE Appy Study, half of surgeons globally were testing patients for SARS-CoV-2 only when symptomatic or there was suspicion of infection; approximately 12 per cent did not test patients at all (Fig. 1 and Table S1). There were regional differences. In Europe, respondents tested all patients (50.8 per cent) or those with suspected infection (43.9 per cent), with only 5.3 per cent not being tested at all. In the USA, the majority of participants only tested patients with a suspected infection (65.6 per cent). A similar picture of testing only those with a suspected infection was also reported from Latin America (57.2 per cent), Asia/Middle East (76.8 per cent), and Africa (41.7 per cent). Even more worrisome, 58.3 per cent of respondents from Africa and 27.6 per cent from Latin America were not testing patients at all before appendicectomy. Concerning the screening modality, most respondents used PCR alone or in combination with chest imaging. Serology was rarely used overall and never in Africa (Fig. 1 and Table S2 ). It is now accepted that chest imaging is not routinely required and that PCR is an accurate screening modality. Serology might, however, be useful to shed light on the disease course and previous exposure to the virus, but respondents from some countries still have restricted access to this test. In terms of PPE during appendicectomy, most African respondents did not use different PPE compared with the prepandemic period in patients who tested negative for COVID-19. More concerning is that 58.3 per cent did not use different PPE in untested patients. This differed from other regions where the rate of those not considering a change of PPE in untested patients did not exceed 22 per cent. One in 10 respondents from Latin America also reported that they were not using different PPE compared with the prepandemic phase in patients who tested positive for COVID-19. These data, and taking into account the high prevalence of acute appendicitis, leads to the conclusion that omission of routine patient screening may have contributed to local clusters among patients and threatened the safety of healthcare workers5. In this respect, it is likely that limited access to PPE explains the attitude of surgeons towards patients with unknown SARSCoV- 2 status or those infected, raising ethical concerns about the safety of surgical staff. It is of outmost importance that, even during challenging times and stress on economic stability, industrialized countries make efforts to sustain low-income countries and those with limited resources. This would ensure equal working conditions, safer treatment for patients with acute appendicitis, and better control of the pandemic

A study of the effect of E-beam (1 and 2 kGy) on the cholesterol oxidation product (COP) composition of fresh and marinated pork loin stored at 4 and 8 °C under different atmospheres (air, vacuum and carbon dioxide enriched) has been carried out for the first time. The combined statistical treatment of the distinct variables showed that minor differences were found in some cholesterol oxidation products of fresh loin due to storage temperature, packaging method and storage time. No effect of irradiation (up to 2 KGy) on the COP amount was found, concluding that E-beam can be a useful tool to extend the shelf-life of fresh and marinated loin without changes in the COP fraction.

- Abstract
Background: Azo pigments are widely used in the textile and leather industry, and they generate diverse contaminants (mainly in wastewater effluents) that affect biological systems, the rhizosphere community, and the natural activities of certain species., Methods: This review was performed according to the Systematic Reviews and Meta Analyses (PRISMA) methodology., Results: In the last decade, the use of Streptomyces species as biological azo-degraders has increased, and these bacteria are mainly isolated from mangroves, dye-contaminated soil, and marine sediments. Azo pigments such as acid orange, indigo carmine, Congo red, and Evans blue are the most studied compounds for degradation, and Streptomyces produces extracellular enzymes such as peroxidase, laccase, and azo reductase. These enzymes cleave the molecule through asymmetric cleavage, followed by oxidative cleavage, desulfonation, deamination, and demethylation. Typically, some lignin-derived and phenolic compounds are used as mediators to improve enzyme activity. The degradation process generates diverse compounds, the majority of which are toxic to human cells and, in some cases, can improve the germination process in some horticulture plants., Conclusions: Future research should include analytical methods to detect all of the molecules that are generated in degradation processes to determine the involved reactions. Moreover, future studies should delve into consortium studies to improve degradation efficiency and observe the relationship between microorganisms to generate scale-up biotechnological applications in the wastewater treatment industry., (© 2024 The Author(s).

- Abstract
Sarcocystis spp. are coccidian protozoans belonging to the Apicomplexa phylum. As with other members of this phylum, they are obligate intracellular parasites with complex cellular machinery for the invasion of host cells. Sarcocystis spp. display dixenous life cycles, involving a predator and a prey as definitive and intermediate hosts, respectively. Specifically, these parasites develop sarcocysts in the tissues of their intermediate hosts, ranging in size from microscopic to visible to the naked eye, depending on the species. When definitive hosts consume sarcocysts, infective forms are produced in the digestive system and discharged into the environment via feces. Consumption of oocyst-contaminated water and pasture by the intermediate host completes the parasitic cycle. More than 200 Sarcocystis spp. have been described to infect wildlife, domestic animals, and humans, some of which are of economic or public health importance. Interestingly, Old World camelids (dromedary, domestic Bactrian camel, and wild Bactrian camel) and New World or South American camelids (llama, alpaca, guanaco, and vicuña) can each be infected by two different Sarcocystis spp: Old World camelids by S. cameli (producing micro- and macroscopic cysts) and S. ippeni (microscopic cysts); and South American camelids by S. aucheniae (macroscopic cysts) and S. masoni (microscopic cysts). Large numbers of Old and New World camelids are bred for meat production, but the finding of macroscopic sarcocysts in carcasses significantly hampers meat commercialization. This review tries to compile the information that is currently accessible regarding the biology, epidemiology, phylogeny, and diagnosis of Sarcocystis spp. that infect Old and New World camelids. In addition, knowledge gaps will be identified to encourage research that will lead to the control of these parasites.

Pacheco-Quito EM, Jaramillo J, Sarmiento-Ordoñez J, and Cuenca-León K
- Abstract
Asthma is a chronic, heterogeneous respiratory pathology characterized by reversible airway inflammation. Therapeutics focus on symptom reduction and control, aimed at preserving normal pulmonary function and inducing bronchodilatation. The objective of this review is to describe the adverse effects produced by anti-asthmatic drugs on dental health, according to the reported scientific evidence. A bibliographic review was carried out on databases, such as Web of science, Scopus, and ScienceDirect. Most anti-asthmatic medications are administered using inhalers or nebulizers, making it impossible to avoid contact of the drug with hard dental tissues and oral mucosa, and thus promoting a greater risk of oral alterations, mainly due to decreases in the salivary flow and pH. Such changes can cause diseases, such as dental caries, dental erosion, tooth loss, periodontal disease, bone resorption, as well as fungal infections, such as oral candidiasis.

- Abstract
Background: The WHO roadmap for neglected tropical diseases includes yaws eradication requiring certification of elimination of transmission in all endemic and formerly endemic countries worldwide. A community-based programme for yaws control was considered to have achieved elimination of the infection in the endemic focus in Ecuador after 1993. We did a serosurvey of children in this focus to provide evidence for interruption of transmission., Methods: Survey of serum samples collected from children aged 2 to 15 years living in the formerly endemic and in geographically contiguous areas. A convenience sample of sera collected between 2005 were 2017 from non-yaws studies, were analyzed using immunochromatic rapid tests to screen (OnSite Syphilis Ab Combo Rapid Test) for Treponema pallidum-specific antibodies and confirm (DPP Syphilis Screen and Confirm) seroreactivity based on the presence antibodies to treponemal and non-treponemal antigens., Results: Seroreactivity was confirmed in 6 (0.14%, 95% CI 0.06-0.30) of 4,432 sera analyzed and was similar in formerly endemic (0.11%, (95% CI 0.01-0.75) and non-endemic (0.14%, 95% CI 0.06-0.34) communities. All seroreactors were of Afro-Ecuadorian ethnicity and most were male (4/6) and aged 10 or more years (5/6), the latter possibly indicating venereal syphilis. Only 1 seroreactor lived in a community in the Rio Santiago, that was formerly hyperendemic for yaws., Conclusion: We observed very low levels of treponemal transmission in both formerly endemic and non-endemic communities which might be indicative of congenital or venereal syphilis and, if yaws, would likely be insufficient to maintain transmission of this endemic childhood infection. Additional surveys of children aged 1 to 5 years are planned in Rio Santiago communities to exclude yaws transmission., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Vulvar masses in children are an unusual finding but their differential diagnosis is extensive. In case of solid masses, rhabdomyosarcoma (RMS) must always be considered due to the fact that it is the most common tumor in external genitals during childhood. However, RMS has a radiological appearance very similar to juvenile xanthogranuloma (JXG). We present a 16-month-old girl with a 2 cm solid mass on her left labia majora, with four overlying cutaneous papules. After imaging tests, an excisional biopsy was programmed due to high malignancy suspicion. Histopathology of the mass and one of the papules was diagnostic for JXG. After a 12-month follow-up, the patient shows no signs of relapse or complication. Deep JXG is an uncommon entity in childhood and exceptional in the genital area. Therefore, it must be included in the differential diagnosis of a solid vulvar mass, especially if accompanying yellowish xanthomatous cutaneous lesions are present., Competing Interests: Conflict of Interest All of the authors declare no conflicts of interest., (The Author(s).

Parra Izquierdo V, Frias-Ordoñez J, Galindo P, Romero-Sanchez C, and Florez C
- Abstract
Background: Tofacitinib is a molecule that inhibits Janus kinases, enzymes involved ulcerative colitis (UC) pathogenesis. This drug has recently been approved by INVIMA (abbreviation in Spanish of National Institute of Food and Drug Surveillance) in Colombia., Objective: to describe real-life experience in Colombian patients with a diagnosis of UC treated with tofacitinib since its approval., Methods: Case series of 6 patients diagnosed with UC with moderate-severe activity defined by the American College of Gastroenterology Ulcerative Colitis Activity Index (ACG score) treated with tofacitinib 10 mg every 12 hours (BID) in the induction and maintenance phase. The decision to use tofacitinib was based on clinical judgment and patient preference. Response to treatment was evaluated in terms of endoscopic (Mayo score), paraclinical (CRP, ESR, fecal Calprotectin, Hemoglobin) and clinical response (absence of abdominal pain, diarrhea, and rectal bleeding). Additionally, adverse events, steroid use and response to extraintestinal manifestations (EIM) were evaluated., Results: Four men and two women with an average age of 35.6 years were included. All 6 patients had moderate to severe UC; 5 patients with pancolitis and 1 with left-colitis. The average time of diagnosis was 4.08 years. Four patients had previously failed TNF-inhibitors (3 Adalimumab, 2 Infliximab, 1 Golimumab), and 2 patients had previously failed integrin alpha-4beta7-inhibitor (Vedolizumab). Two patients were naïve to biological therapy. Three patients were at risk of colectomy due to severe disease activity. Three patients presented EIM. During the induction phase, 1 maintained disease activity without response, 5 presented clinical and paraclinical remission, 20% remained in moderate-severe activity, 20% mild activity and 60% in remission, the 3 patients who were at risk of colectomy were ruled out from surgery due to symptom improvement. At the endoscopic level, 3 endoscopic studies were obtained in the end of induction, of which 1 presented a Mayo score 3, and 2 patients with Mayo score 1. For naïve patients to biological therapy, one achieved clinical and paraclinical remission upon induction, the endoscopic response still has not been measured, in the second naive patient, tofacitinib was used in-hospital since he didn't respond to intravenous steroids for 72 hours and there was no availability of infliximab, ruling out other predisposing factors to exacerbation, achieving the discharge with adequate symptoms control and paraclinical findings. Three patients discontinued corticosteroids, and three patients achieved dose reduction. One patient reported and adverse event, none had drug-associated leukopenia, and 3 of them without lipid alteration after induction. All patients resolved their EIM during induction. Only one patient has completed follow-up during maintenance for 26 weeks, which is in clinical, paraclinical and endoscopic remission with a dose of 10 mg BID, 1 patient at 16 weeks decided to suspend the medication due to lack of response and the other 4 patients are in clinical and paraclinical remission but have not completed the 26 weeks of maintenance and have a follow-up appointment pending., Conclusion: The results of this case report suggest that tofacitinib may be an effective therapeutic alternative in patients with moderate to severe UC and associated extraintestinal manifestations, with a good safety profile., (Copyright © 2021 by The American College of Gastroenterology.)

Parra Izquierdo V, Frias-Ordoñez J, Romero-Sanchez C, Alvarado J, and Florez C
- Abstract
Case: Background: Metastatic Crohn's disease (MCD) is an unusual cutaneous manifestation in Crohn's disease (CD), and concomitant oral and vulvar involvement is even more unusual. It can debut with cavity lesions oral such as canker sores, ulcers, lip edema, granulomatosis, dry mouth, abscesses in the salivary ducts, erythema, gingivitis, glossitis, among others, however, simultaneous compromise with several oral lesions and so severe with loss of multiple pieces dental is very rare., Case Presentation: Patient in the fourth decade of life with a family history of autoimmunity who debuts with severe oral manifestations with a requirement for extraction of 14 teeth, severe gingivitis, smooth tongue and glossitis, aphthous stomatitis, ulcers, lip edema and angular cheilitis, without clear cause, and in management by the oral pathology group. Associated with this, there was vulvo-perineal compromise with ulcerated, inflammatory, erythematous and infiltrated lesions. It was initially suspected of Behçet's disease, HLA B51 was performed, it was negative, also, negative pathergy test, and no other suggestive systemic findings. A vulvar biopsy was performed with marked edema of the dermis, dilated lymphatics with perivascular and interstitial lymphoplasmacytic infiltrate and noncaseating granulomas, negative for microorganisms. At this level, it was compatible with MCD, without presence of gastrointestinal symptoms and calprotectin levels in stool in normal range. High and low endoscopic studies and capsule endoscopy were performed in small intestine, without alterations, it was managed by dermatology with topical steroids and by dentistry with dental implants. It was considered patient with inflammatory bowel disease (IBD) type CD with severe extraintestinal manifestations (EIM), although it did not present compromise intestinal treatment, it was decided to start treatment with anti-TNF initially with adalimumab developing paradoxical psoriasis, later treatment with infliximab, again with presentation of severe paradoxical psoriasis, for which it was suspended. Cyclosporine was also used as an immunomodulator, presenting intolerable tachycardia. 18 months after these symptoms, she presented episcleritis of the left eye and begins with colicky abdominal pain and average diarrheal stools 5-a-day, it was performed high and low endoscopic studies without alterations and new capsule endoscopic of small intestine documenting Crohn's enteritis involving the duodenum, jejunum and ileum, considering a patient with IBD type CD, with EIM with vulvo-perineal compromise, severe oral involvement and episcleritis. Currently is under management with azathioprine and Ustekinumab, with clinical improvement significant., Conclusions: MCD represents a diagnostic challenge, it can debut without gastrointestinal involvement, and its clinical and histopathological findings simulate other entities. A timely diagnosis is required to seek early benefit in the patient., (Copyright © 2021 by The American College of Gastroenterology.)

- Abstract
Background: Damage control surgery (DCS) has emerged as a new option in the management of non-traumatic peritonitis patients to increase survival in critically ill patients. The purpose of this study was to compare DCS with conventional strategy (anastomosis/ostomies in the index laparotomy) for severe non-traumatic peritonitis regarding postoperative complications, ostomy rate, and mortality and to propose a useful algorithm in the clinical practice., Methods: Patients who underwent an urgent laparotomy for non-trauma peritonitis at a single level I trauma center in Colombia between January 2003 and December 2018, were retrospectively included. We compared patients who had DCS management versus definitive initial surgical management (DISM) group. We evaluated clinical outcomes and morbidities among groups., Results: 290 patients were included; 81 patients were treated with DCS and 209 patients underwent DISM. Patients treated with DCS had a worse critical status before surgery with higher SOFA score [median, DCS group: 5 (IQR: 3-8) vs. DISM group: 3 (IQR: 1-6), p < 0.001]. The length of hospital stay and overall mortality rate of DCS group were not significant statistical differences with DISM group. Complications rate related to primary anastomosis or primary ostomy was similar. There is not difference in ostomy rate among groups. At multivariate analysis, SOFA > 6 points and APACHE-II > 20 points correlated with a higher probability of DCS., Conclusion: DCS in severe non-trauma peritonitis patients is feasible and safe as surgical strategy management without increasing mortality, length hospital of stay, or complications. DCS principles might be applied in the non-trauma scenarios without increase the stoma rate.

- Abstract
The management of different industrial by-products, such as recycled aggregates from construction and demolition waste and alumina by-products, as well as the reduction of landfill deposits by incorporating these products in a second life cycle, were the focus of this work. The aim of this study was to demonstrate the technical viability of using these waste and by-product as a material for road pavement base layers. For this purpose, a real-scale application was carried out, and the behavior of three types of materials, applied on a section of an experimental road under real vehicle traffic conditions, was studied and compared. Three materials were used in these sections applied in the road sub-bases. First, a control material composed of a type of artificial gravel was used to be compared with the rest of materials; the second material was composed of recycled aggregates, and the third was composed of a mix of recycled aggregates and alumina waste. The results concluded that the effectiveness of the sections built using recycled aggregates and alumina waste was very positive and similar those constructed using natural aggregates.

- Abstract
Background: Cutaneous carcinosarcoma is a rare biphasic tumor comprising malignant epithelial and heterologous mesenchymal elements. Data on the clinical and histopathologic characteristics of this tumor are scarce. The objective of this study was to describe the clinicopathologic and immunohistochemical features of cutaneous carcinosarcoma., Methods: A descriptive retrospective study was conducted in a tertiary care hospital from Spain. We reviewed the records of eight patients with cutaneous carcinosarcoma who were diagnosed from 2009 to 2019., Results: The mean patient age at diagnosis was 72.13 years (range 44-91 years), and there was a male predilection (6 cases). The most common site of cutaneous carcinosarcoma was the head and neck (5 cases). Carcinosarcomas demonstrated variable histopathological and immunohistochemical features. Follow-up was available for 7-8 patients. There were two cases of local recurrence and one case of metastasis. Two patients died from the tumor during the entire follow-up., Conclusions: Although the number of cases in this study was limited, our results provide valuable insight into the clinical, histopathologic, and immunohistochemical characteristics of primary cutaneous carcinosarcoma., (© 2020 the International Society of Dermatology.)

- Abstract
Damage control resuscitation should be initiated as soon as possible after a trauma event to avoid metabolic decompensation and high mortality rates. The aim of this article is to assess the position of the Trauma and Emergency Surgery Group (CTE) from Cali, Colombia regarding prehospital care, and to present our experience in the implementation of the "Stop the Bleed" initiative within Latin America. Prehospital care is phase 0 of damage control resuscitation. Prehospital damage control must follow the guidelines proposed by the "Stop the Bleed" initiative. We identified that prehospital personnel have a better perception of hemostatic techniques such as tourniquet use than the hospital providers. The use of tourniquets is recommended as a measure to control bleeding. Fluid management should be initiated using low volume crystalloids, ideally 250 cc boluses, maintaining the principle of permissive hypotension with a systolic blood pressure range between 80- and 90-mm Hg. Hypothermia must be management using warmed blankets or the administration of intravenous fluids warmed prior to infusion. However, these prehospital measures should not delay the transfer time of a patient from the scene to the hospital. To conclude, prehospital damage control measures are the first steps in the control of bleeding and the initiation of hemostatic resuscitation in the traumatically injured patient. Early interventions without increasing the transfer time to a hospital are the keys to increase survival rate of severe trauma patients., Competing Interests: Conflict of Interest: the authors declare not to have any conflict of interest, (Copyright © 2020 Colombia Medica.)

- Abstract
Objectives: To describe the adsorption of ticarcillin and piperacillin on to polyethersulfone (PES) membranes using the recirculation function on an ex-vivo renal replacement circuit., Methods: Low (4-8 mg) or high (35-45 mg) doses of ticarcillin and low (4-8 mg) or high (70-80 mg) doses of piperacillin were added to 1 L of human blood-crystalloid mixture and circulated around an ex-vivo modified continuous renal replacement therapy machine at three different blood flow settings (150, 300 and 450 mL/min). Plasma samples were collected from the pre-filter port of the haemodiafilter circuit at consecutive timepoints for a total duration of 4 h. Plasma samples were measured using a validated ultra high performance liquid chromatography-tandem mass spectrometry method., Results: Eighty-one samples including both drugs were collected from 18 experimental runs. Overall, the percentage of piperacillin adsorption for the low and high doses ranged from 21.3% to 27.1% and from 11.5% to 23%, and the percentage of ticarcillin adsorption for the low and high doses ranged from 4.2% to 14.3% and from 3.7% to 15.1%, respectively. The low dose of piperacillin consistently yielded more than 20% adsorption of dose for all blood flow rates. This decreased with high blood flow rates when the high dose of piperacillin was used. Ticarcillin generally displayed ≤5% adsorption, with the exceptions being the high dose at 150 mL/min and the low dose at 300 mL/min, which displayed ~15% adsorption., Conclusions: Adsorption of both drugs tended to be higher at the lowest blood flow rates and lowest doses. This is likely due to saturation of parts of the filter that have a chemical attraction to both piperacillin and ticarcillin. At low doses at all three blood flow rates, piperacillin demonstrated >20% adsorption, whereas ticarcillin tended to have low rates (up to ~≤15%) of adsorption on to PES membrane filters., (Crown Copyright © 2020.

- Abstract
The aim of this study was to describe the population pharmacokinetics of ticarcillin during extended daily diafiltration (EDDf) in critically ill patients with acute kidney injury. Blood samples were collected from critically ill patients prescribed ticarcillin during one to two dosing intervals during which EDDf was performed. Plasma samples were measured using a validated ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method. Concentration-time data were analysed using a population pharmacokinetics approach with Pmetrics®. A total of 53 blood samples were collected from six critically ill patients (three male). The mean ± standard deviation patient age, weight and body mass index (BMI) was 43 ± 22 years, 88 ± 14 kg and 31 ± 5 kg/m
2 , respectively. A two-compartment linear model adequately described the data. Median population pharmacokinetic parameter estimates were as follows: clearance in the presence of EDDf (CLEDDf ), 6.41 L/h; clearance of EDDf (CLnon-EDDf ), 4.97 L/h; volume of distribution of the central compartment (Vc ), 56.46 L; intercompartmental clearance from the central to peripheral compartment (kCP ), 13.54 L/h; and intercompartmental clearance from the peripheral to central compartment (kPC ), 21.93 L/h. This is the first population pharmacokinetic model of ticarcillin in patients receiving EDDf. Large pharmacokinetic variability was found, supporting further investigation of the pharmacokinetics of less-studied β-lactam antibiotics in prolonged intermittent renal replacement therapy., (Copyright © 2019 Elsevier Ltd.

- Abstract
Introduction: New digital thoracic drainage systems allow an objective measurement of air leakage. They have proven their usefulness in the postoperative thoracic surgery in adults, but there is little experience with its use in the pediatric population. The objective of our study is to analyze their safety and effectiveness in the postoperative period of the pediatric patients., Method: A prospective consecutive observational study was done. All patients submitted to pulmonary resection between 2011 and 2017 and in whom digital thoracic drainage system was used (Thopaz Chest Drain System, Medela, Switzerland) were prospectively enrolled in this study. We analyzed variables: duration of chest tube (CT), days of hospitalization and radiographs in the immediate postoperative period related to the presence of CT. This group was compared with a historical cohort of patients (from 2011 to 2015) with a pulmonary resection in whom the traditional thoracic drainage was used. For the statistical analysis, the Mann-Whitney U-Test was used for independent samples., Result: Twenty-six patients were included, Digital drainage system was used in13 patients and traditional drainage was used in 13 patients. The median age was 18 months (12 days-14 years). The mean number of days with the chest tube was 1.69 ± 0.6 in digital drainage group versus 5.38 ± 4 days in traditional drainage group (p < 0.05) The mean number of postoperative radiographs was 2.8 ± 1.1 in digital drainage group versus 6.23 ± 5.2 radiographs in traditional drainage group (p < 0.05). The average hospital stay in digital drainage group was 5.69 ± 2.7 days versus 7 ± 4.7 days in the traditional drainage group (p > 0.05). No complications related to the use of digital drainage group were registered., Conclusion: The digital thoracic drainage systems provide an objective measurement of air leakage, allowing early chest tube removal and decreasing the number of radiographs performed postoperatively. Its use in the pediatric population appears to be safe and potentially beneficial., Level of Evidence: II., (Copyright © 2018 Elsevier Inc. All rights reserved.)

- Abstract
The energy consumption-growth nexus has been widely studied in the empirical literature, though results have been inconclusive regarding the direction, or even the existence, of causality. These inconsistent results can be explained by two important limitations of the literature. First, the use of bivariate models, which fail to detect more complex causal relations, or the ad hoc approach to selecting variables in a multivariate framework; and, second, the use of linear causal models, which are unable to capture more complex nonlinear causal relationships. In this paper, we aim to overcome both limitations by analysing the energy consumption-growth nexus using a Flexible Fourier form due to Enders and Jones (2016). The analysis focuses on the US over the period 1949 to 2014. From our results we can conclude that, where the linear methodology supports the neutrality hypothesis (no causality between energy consumption and growth), the Flexible Fourier form points to the existence of causality from energy consumption to growth. This is contrary to the linear analysis, suggesting that lowering energy consumption would adversely affect US economic growth. Thus, by employing the Flexible Fourier form we find the conclusions can be quite different., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: Direct diagnosis of small intestinal bacterial overgrowth (SIBO) requires the collection and culture of fluid from the jejunal lumen, with a finding of over 10
5 viable bacteria per mL. More often, SIBO is diagnosed indirectly, using a non-invasive test of the exhaled hydrogen and methane generated by microbial fermentation when ingested glucose reaches the jejunum. Our objective was to determine how well this breath test detects chronic overgrowth of jejunal bacteria that is unrelated to gastrointestinal surgery., Methods: Eighteen patients reporting symptoms consistent with SIBO received a glucose breath test. On a later day, the jejunal lumen was sampled via aspiration during enteroscopy. Jejunal aspirates were cultured on aerobic and anaerobic media. DNA was extracted from the same samples and analyzed by quantitative pan-bacterial PCR amplification of 16S ribosomal rRNA genes, which provided a culture-independent bacterial cell count., Key Results: Combined bacterial colony counts ranged from 5.7 x 103 to 7.9 x 106 CFU/mL. DNA-based yields ranged from 1.5 x 105 to 3.1 x 107 bacterial genomes per mL. Microbial viability ranged from 0.3% to near 100%. We found no significant correlation of glucose breath test results with either the number of bacterial colonies or with the DNA-based bacterial cell counts. Instead, higher signals in the hydrogen-methane breath test were significantly correlated with a lower viability of jejunal bacteria, at a P-value of .014., Conclusions & Inferences: The glucose-based hydrogen and methane breath test is not sensitive to the overgrowth of jejunal bacteria. However, a positive breath test may indicate altered jejunal function and microbial dysbiosis., (© 2018 John Wiley & Sons Ltd.)- Published

- Abstract
Severe sepsis or septic shock are the main factors influencing the prognosis of acute pyelonephritis (APN). Our aim was to analyze factors associated with the development of severe sepsis or septic shock in a large sample of patients with acute complicated pyelonephritis (ACPN).This prospective observational study comprised 1507 consecutive patients aged 14 years or older who were admitted to a tertiary care hospital because of ACPN between 1997 and 2015. Covariates associated in univariate analysis with severe sepsis or septic shock were then analyzed by multivariate logistic regression.Of the 1507 patients, 423 (28.1%) fulfilled the criteria for severe sepsis or septic shock at the time of admission. Crude and attributable mortality at 30 days were 17.7% and 11.7% in patients with severe sepsis or septic shock versus 1.7% and 0.6% in patients without severe sepsis or septic shock, P < .0001 and P < .0005, respectively. An age > 65 years, urinary instrumentation in the previous 2 weeks, the lack of mictional syndrome or costovertebral tenderness, an ectasia ≥ grade II, and bacteremia were independent risk factors associated with severe sepsis or septic shock.The prevalence of severe sepsis and septic shock in patients with ACPN is high. Some factors associated with severe sepsis are easy to identify in any emergency department. The information provided here could be useful when deciding which patients should be admitted to receive immediate treatment.

- Abstract
Background: The upper half of the human small intestine, known as the jejunum, is the primary site for absorption of nutrient-derived carbohydrates, amino acids, small peptides, and vitamins. In contrast to the colon, which contains 10
11 -1012 colony forming units of bacteria per ml (CFU/ml), the normal jejunum generally ranges from 103 to 105 CFU per ml. Because invasive procedures are required to access the jejunum, much less is known about its bacterial microbiota. Bacteria inhabiting the jejunal lumen have been investigated by classical culture techniques, but not by culture-independent metagenomics., Results: The lumen of the upper jejunum was sampled during enteroscopy of 20 research subjects. Culture on aerobic and anaerobic media gave live bacterial counts ranging from 5.8 × 103 CFU/ml to 8.0 × 106 CFU/ml. DNA from the same samples was analyzed by 16S rRNA gene-specific quantitative PCR, yielding values from 1.5 × 105 to 3.1 × 107 bacterial genomes per ml. When calculated for each sample, estimated bacterial viability ranged from effectively 100% to a low of 0.3%. 16S rRNA metagenomic analysis of uncultured bacteria by Illumina MiSeq sequencing gave detailed microbial composition by phylum, genus and species. The genera Streptococcus, Prevotella, Veillonella and Fusobacterium, were especially abundant, as well as non-oral genera including Escherichia, Klebsiella, and Citrobacter. The jejunum was devoid of the genera Alistipes, Ruminococcus, Faecalibacterium, and other extreme anaerobes abundant in the colon. In patients with higher bacterial loads, there was no significant change in microbial species composition., Conclusions: The jejunal lumen contains a distinctive bacterial population consisting primarily of facultative anaerobes and oxygen-tolerant obligate anaerobes similar to those found in the oral cavity. However, the frequent abundance of Enterobacteriaceae represents a major difference from oral microbiota. Although a few genera are shared with the colon, we found no evidence for retrograde movement of the most abundant colonic microbes to the jejunum. Some individuals had much higher bacterial loads, but this was not correlated with decreases in bacterial species diversity or other evidence of dysbiosis.- Published

240. Sediment size distribution and composition in a reservoir affected by severe water level fluctuations.

López P, López-Tarazón JA, Casas-Ruiz JP, Pompeo M, Ordoñez J, and Muñoz I
- Abstract
The reservoir sediments are important sinks for organic carbon (OC), the OC burial being dependent on two opposite processes, deposition and mineralization. Hence factors such as severe water level fluctuations are expected to influence the rate of OC accumulation as they may affect both deposition and mineralization. The Barasona Reservoir has been historically threatened by siltation, whilst the use of water for irrigation involves a drastic decrease of the water level. In this context, we have studied the physical and chemical characteristics (grain size, major and minor elemental compositions, organic and inorganic carbon, and nitrogen) of the recent sediments of the Barasona Reservoir and the relationships among them in order to: a) elucidate the main processes governing OC accumulation, b) evaluate the rate of OC mineralization and c) approach the effect of drought on the sediment characteristics in this system. Our results indicated that Barasona sediments were dominated by fine silts (>60%) and clays (>20%), the mean particle size decreasing from tail to dam. Desiccation increased particle sorting and size distribution became bimodal, but no effect on average size was observed. Attending to the composition, Barasona sediments were very homogeneous with low concentrations of nitrogen (TN) and phosphorus (<1.2 g kg(-1) dw and <0.6 g kg(-1) dw, respectively) and high concentration of OC (≈36 g kg(-1) dw). TN was negatively related to dry weight. Sediment mixing due to drastic changes in water level may have favoured the observed homogeneity of Barasona sediments affecting carbon, major ions and grain size. The high amount of OC deposited in Barasona sediment suggested that the adsorption of OC onto fine particles was more important than in boreal lakes. The rate of oxygen consumption by wet sediment ranged from 2.26 to 3.15 mg O2 m(-2) day(-1), values close to those compiled for Mediterranean running waters., (Copyright © 2015 Elsevier B.V.

- Abstract
Objectives: To determine the ability of urinary neutrophil gelatinase-associated lipocalin (uNGAL) to predict cardiac surgery-associated acute kidney injury (CSA-AKI), continuous renal replacement therapy (CRRT), mortality, and a composite outcome of major adverse kidney events at 365 days (MAKE365), and to investigate the influence of cardiopulmonary bypass (CPB) on NGAL release., Design: A prospective observational study., Setting: A single-center university hospital., Participants: A cohort of 288 adult cardiac surgery patients., Interventions: uNGAL was measured at baseline, immediately after surgery, and on days 1 and 2 postoperatively. The authors used the recent Kidney Disease Improving Global Outcomes consensus criteria to define CSA-AKI., Measurements and Main Results: CSA-AKI occurred in 36.1% of patients. uNGAL rapidly became significantly higher in patients who developed AKI, with peak value immediately after surgery (349.9 [76.6-1446.6] v 90.1 [20.8-328] ng/mg creatinine; p<0.001). No measure of uNGAL (peak, postsurgery, day 1 or 2 postsurgery) accurately predicted CSA-AKI, CRRT, mortality, or MAKE365. However, immediately after surgery, CPB induced greater uNGAL release compared with off-pump surgery (265.5 µmol/L [71-989.6] v 48.7 ng/mg creatinine [17-129.8]; p<0.001). Moreover, such early uNGAL release correlated with CPB duration (r = 0.505; p<0.001) but not with peak serum creatinine values on day 3 or 7 after surgery., Conclusions: uNGAL had a limited predictive ability for CSA-AKI or other relevant clinical outcomes after cardiac surgery and appeared to be more closely related to the use and duration of CPB. Thus, its levels may represent the aggregate effect of an inflammatory response to CPB as well as a renal response to cardiac surgery and inflammation., (Copyright © 2015 Elsevier Inc.

- Abstract
Purpose: The aim of this prospective and multicentric phase II study was to evaluate the efficacy and safety of temozolomide (TMZ) and bevacizumab (BV) in patients (pts) with recurrent glioblastoma (GB), previously treated with chemoradiotherapy and at least three cycles of adjuvant TMZ., Patients and Methods: Patients with GB at first relapse received BV 10 mg/kg day every 2 weeks and TMZ 150 mg/m(2) days 1-7 and 15-21, every 28 days. Patients underwent brain magnetic resonance imaging every 8 weeks., Results: Thirty-two evaluable pts were recruited in 8 sites. Fourteen pts (44%) had gross total resection. O(6)-methylguanine-DNA methyltransferase (MGMT) promoter was methylated in 12 pts, unmethylated in 6 pts, and missing in 14 pts. The estimated 6-month progression free survival (PFS) rate was 21.9% (95% CI 9.3-40.0%). The median PFS and overall survival (OS) were 4.2 months (95% CI 3.6-5.4 months) and 7.3 months (95% CI 5.8-8.8 months), respectively. No significant association with MGMT status was found in terms of OS or PFS. Six of 32 pts (19%; 95% CI 7.2-36.4) were long-term survivors, with a median PFS and OS (50% events) of 9.5 months (95% CI 7.9-23.6) and 15.4 (95% CI 8.9-NA), respectively: no differences in baseline characteristics were identified in comparison with total population. No unexpected toxicities or treatment-related deaths were observed., Conclusions: This regimen showed to be feasible and well tolerated in pts with recurrent GB pretreated with TMZ. Further investigation is warranted to identify subpopulations that are more likely to benefit from addition of BV to GB therapy.

- Abstract
Previous studies report a higher risk of cancer in patients with ESRD, but the impact of less severe CKD on risk of cancer is uncertain. Our objective was to evaluate the association between level of kidney function and subsequent cancer risk. We performed a retrospective cohort study of 1,190,538 adults who were receiving care within a health care delivery system, had a measurement of kidney function obtained between 2000 and 2008, and had no prior cancer. We examined the association between level of eGFR and the risk of incident cancer; the primary outcome was renal cancer, and secondary outcomes were any cancer and specific cancers (urothelial, prostate, breast, lung, and colorectal). During 6,000,420 person-years of follow-up, we identified 76,809 incident cancers in 72,875 subjects. After adjustment for time-updated confounders, lower eGFR (in milliliters per minute per 1.73 m(2)) was associated with an increased risk of renal cancer (adjusted hazard ratio [HR], 1.39; 95% confidence interval [95% CI], 1.22 to 1.58 for eGFR=45-59; HR, 1.81; 95% CI, 1.51 to 2.17 for eGFR=30-44; HR, 2.28; 95% CI, 1.78 to 2.92 for eGFR<30). We also observed an increased risk of urothelial cancer at eGFR<30 but no significant associations between eGFR and prostate, breast, lung, colorectal, or any cancer overall. In conclusion, reduced eGFR is associated with an independently higher risk of renal and urothelial cancer but not other cancer types., (Copyright © 2014 by the American Society of Nephrology.)

- Abstract
Lipoprotein Lp(a) levels are highly heritable and are associated with cardiovascular risk. We performed a genome-wide linkage analysis to delineate the genomic regions that influence the concentration of Lp(a) in families from the Genetic Analysis of Idiopathic Thrombophilia (GAIT) Project. Lp(a) levels were measured in 387 individuals belonging to 21 extended Spanish families. A total of 485 DNA microsatellite markers were genotyped to provide a 7.1 cM genetic map. The variance component linkage method was used to evaluate linkage and to detect quantitative trait loci (QTLs). The main QTL that showed strong evidence of linkage with Lp(a) levels was located at the structural gene for apo(a) on chromosome 6 (LOD score=13.8). Interestingly, another QTL influencing Lp(a) concentration was located on chromosome 2 with an LOD score of 2.01. This region contains several candidate genes. One of them is the tissue factor pathway inhibitor (TFPI), which has antithrombotic action and also has the ability to bind lipoproteins. However, quantitative trait association analyses performed with 12 SNPs in TFPI gene revealed no association with Lp(a) levels. Our study confirms previous results on the genetic basis of Lp(a) levels. In addition, we report a new QTL on chromosome 2 involved in the quantitative variation of Lp(a). These data should serve as the basis for further detection of candidate genes and to elucidate the relationship between the concentration of Lp(a) and cardiovascular risk.

- Abstract
Extracellular and intraneuronal formation of amyloid-beta aggregates have been demonstrated to be involved in the pathogenesis of Alzheimer's disease. However, the precise mechanism of amyloid-beta neurotoxicity is not completely understood. Previous studies suggest that binding of amyloid-beta to a number of targets have deleterious effects on cellular functions. In the present study we have shown for the first time that amyloid-beta 1-42 bound to a peptide comprising the microtubule binding domain of the heavy chain of microtubule-associated protein 1B by the screening of a human brain cDNA library expressed on M13 phage. This interaction may explain, in part, the loss of neuronal cytoskeletal integrity, impairment of microtubule-dependent transport and synaptic dysfunction observed previously in Alzheimer's disease.

No significant difference (p > 0.05) was observed in the specific aminopeptidase activity (SAA) developed by Pseudomonas fluorescens, P. putida and Flavobacterium odoratum either growing at pH 5.0-6.5 or at 7 and 12 degrees C. Nevertheless, a significant difference was found when comparing the SAA of these organisms. The SAA of F. odoratum was lower than those of pseudomonads. The 4-nitroaniline test is reliable to estimate the G(-) load of fresh food products.

- Abstract
There is limited information about the true incidence of acute renal failure (ARF). Most studies could not quantify disease frequency in the general population as they are hospital-based and confounded by variations in threshold and the rate of hospitalization. Earlier studies relied on diagnostic codes to identify non-dialysis requiring ARF. These underestimated disease incidence since the codes have low sensitivity. Here we quantified the incidence of non-dialysis and dialysis-requiring ARF among members of a large integrated health care delivery system - Kaiser Permanente of Northern California. Non-dialysis requiring ARF was identified using changes in inpatient serum creatinine values. Between 1996 and 2003, the incidence of non-dialysis requiring ARF increased from 322.7 to 522.4 whereas that of dialysis-requiring ARF increased from 19.5 to 29.5 per 100,000 person-years. ARF was more common in men and among the elderly, although those aged 80 years or more were less likely to receive acute dialysis treatment. We conclude that the use of serum creatinine measurements to identify cases of non-dialysis requiring ARF resulted in much higher estimates of disease incidence compared with previous studies. Both dialysis-requiring and non-dialysis requiring ARFs are becoming more common. Our data underscore the public health importance of ARF.

- Abstract
Objective: Describe the epidemiological characteristics of severe burn patients and analyze the factors related with morbidity-mortality., Design and Scope: Observational, retrospective study of patients admitted to an intensive care unit of a level III hospital due to severe burns from January 1998 to December 2004., Patients: 59 patients with criteria of "severe burn" and expected stay in ICU greater than three days. MAIN ENDPOINTS OF INTEREST: We studied epidemiological endpoints of this type of patients, diagnosis and initial treatment, early complications and morbidity-mortality., Results: The burned body surface was 41% +/- 25% and age 49 +/- 21 years. Patients remained hospitalized in ICU for a median of 4 days (interquartile range: 2-19). A total of 78% of the patients needed mechanical ventilation, 47% had some infection during admission and 28% developed acute kidney failure during the first week. Mortality in the ICU was 42%. Endpoints associated independently with a significant increase of mortality were burned body surface greater than 35% (OR 1.08; 95% CI: 1.03-1.12) and development of kidney failure (OR 5.47; 95% CI: 2.02 -8.93)., Conclusions: Mortality of these patients is very high and is conditioned largely by initial care. Percentage of burned body surface (BBS) and kidney failure entails greater mortality in our series.

- Abstract
Rates of ESRD are rising faster in Hispanic than non-Hispanic white individuals, but reasons for this are unclear. Whether rates of cardiovascular events and mortality differ among Hispanic and non-Hispanic white patients with chronic kidney disease (CKD) also is not well understood. Therefore, this study examined the associations between Hispanic ethnicity and risks for ESRD, cardiovascular events, and death in patients with CKD. A total of 39,550 patients with stages 3 to 4 CKD from Kaiser Permanente of Northern California were included. Hispanic ethnicity was obtained from self-report supplemented by surname matching. GFR was estimated from the abbreviated Modification of Diet in Renal Disease equation, and clinical outcomes, patient characteristics, and longitudinal medication use were ascertained from health plan databases and state mortality files. After adjustment for sociodemographic characteristics, Hispanic ethnicity was associated with an increased risk for ESRD (hazard ratio [HR] 1.93; 95% confidence interval [CI] 1.72 to 2.17) when compared with non-Hispanic white patients, which was attenuated after controlling for diabetes and insulin use (HR 1.50; 95% CI 1.33 to 1.69). After further adjustment for potential confounders, Hispanic ethnicity remained independently associated with an increased risk for ESRD (HR 1.33; 95% CI 1.17 to 1.52) as well as a lower risk for cardiovascular events (HR 0.82; 95% CI 0.76 to 0.88) and death (HR 0.72; 95% CI 0.66 to 0.79). Among a large cohort of patients with CKD, Hispanic ethnicity was associated with lower rates of death and cardiovascular events and a higher rate of progression to ESRD. The higher prevalence of diabetes among Hispanic patients only partially explained the increased risk for ESRD. Further studies are required to elucidate the cause(s) of ethnic disparities in CKD-associated outcomes.
