RESUMEN
BACKGROUND: The aim of this study was to assess the impact of ileostomy closure following preoperative physiological stimulation (PPS) on postoperative ileus (POI) in patients with loop ileostomy after low anterior resection for rectal cancer. METHODS: Patients who underwent ileostomy closure between January 2017 and February 2020 in two tertiary referral centers were prospectively included. PPS stimulation was compared to standard treatment. Stimulation was carried out daily during the 15 days prior to ileostomy closure by the patient's self-instillation of 200 ml of fecal contents from the ileostomy bag via the efferent loop, using a rectal catheter. Standard treatment (ST) consisted of observation. Outcomes measures were POI, morbidity, stimulation feasibility, and predictors to ileus. RESULTS: A total of 58 patients were included [42 males and 16 females, median age 67 (43-85) years]. PPS was used in 24 patients, who completed the entire stimulation process, and ST in 34 patients. No differences in preoperative factors were found between the two groups. POI was significantly lower in the PPS group (4.2%) vs the ST group (32.4%); p < 0.01, OR: 0.05 (CI 95% 0.01-0.65). The PPS group had a shorter time to restoration of bowel function (1 day vs 3 days) p = 0.02 and a shorter time to tolerance of liquids (1 day vs 2 days), p = 0.04. Age (p = 0.01), open approach at index surgery, p = 0.03, adjuvant capecitabine (p = 0.01). and previous abdominal surgeries (p = 0.02) were associated with POI in the multivariate analysis. C-reactive-protein values on the 3rd (p = 0.02) and 5th (p < 0.01) postoperative day were also associated with POI. CONCLUSIONS: PPS for patients who underwent ileostomy closure after low anterior resection for rectal cancer is feasible and might reduce POI.

AIM: The aim of the study was to compare the incidence of perineal hernia and the perineal wound morbidity following extralevator abdominoperineal excision (ELAPE) between two groups - primary perineal closure and reconstruction with a biological mesh. METHOD: One hundred and forty-seven consecutive patients who underwent ELAPE for primary rectal cancer between January 2007 and December 2018 in two tertiary referral centres were retrospectively identified from prospective databases. Perineal closure was carried out via primary closure or with a biological mesh (porcine dermal collagen mesh). Outcome measures were perineal hernia and perineal wound morbidity (infection, dehiscence, persistent sinus and chronic pain). RESULTS: A total of 139 patients were included in the study. A prophylactic mesh was used in 80 (57.5%) and primary closure was practised in 59 (42.4%) patients. The median follow-up was 30 (interquartile range 46.88) months. Thirty patients (21.6%) developed perineal hernia. No significant differences were found between prophylactic mesh and primary closure (16.3% vs 23.3%, P = 0.07). The median period between surgery and hernia diagnosis was 8 months in the primary closure group and 24 months in the mesh group (P < 0.01). Perineal wound morbidity was significantly higher in the prophylactic mesh group (55% vs 33.9%, P < 0.01). CONCLUSION: In our study, the use of a biological mesh did not reduce the rate of perineal hernia, although it did delay its appearance. Perineal closure using a biological mesh may increase perineal morbidity, both acute and chronic.

In 2007, the United States successfully eliminated canine rabies virus variant. Globally, however, dogs remain the principal source of human rabies infections. Since 2007, three cases of canine rabies virus variant were reported in dogs imported into the United States, one each from India (2007), Iraq (2008), and Egypt (2015) (1-3). On December 20, 2017, a dog imported into the United States from Egypt was identified with rabies, representing the second case from Egypt in 3 years. An Egyptian-based animal rescue organization delivered four dogs from Cairo, Egypt, to a flight parent (a person solicited through social media, often not affiliated with the rescue organization, and usually compensated with an airline ticket), who transported the dogs to the United States. The flight parent arrived at John F. Kennedy International Airport (JFK) in New York City and, via transporters (persons who shuttle dogs from one state to another), transferred the dogs to foster families; the dogs ultimately were adopted in three states. The Connecticut Department of Public Health Laboratory (CDPHL) confirmed the presence of a canine rabies virus variant in one of the dogs, a male aged 6 months that was adopted by a Connecticut family. An investigation revealed the possibility of falsified rabies vaccination documentation presented on entry at JFK, allowing the unvaccinated dog entry to the United States. This report highlights the continuing risk posed by the importation of dogs inadequately vaccinated against rabies from high-risk countries and the difficulties in verifying any imported dog's health status and rabies vaccination history.

Blastocystis sp. is a widespread microorganism that colonizes the intestinal tract of several animals, including human beings, while its pathogenic role in humans is still under debate. The objective of the present study was to describe the frequency of Blastocystis sp. subtypes (STs) and their genetic variation within and among samples recovered from scholars inhabiting two rural villages with tropical climates and compare this information with previously documented data from arid and temperate zones in Mexico. Blastocystis sp. positive samples and ST identification were achieved by coprological analysis screening and Polymerase Chain Reaction-sequencing, respectively. Classical population genetics indexes (nucleotide diversity (π), haplotype polymorphism (θ), gene flow (Nm), genetic differentiation (ST), and Tajima's D) were calculated by comparing the sequences here obtained (n = 42) and those from previous studies from the arid (n = 80) and temperate (n = 61) climates from Mexico. Although Blastocystis sp. was the parasite most frequently found between 33% and 26% in both communities, only STs 1-3 were found. Haplotype network inference of Blastocystis sp. STs showed different haplotype profiles among STs vs. climate zones, although no specific haplotypes were identified for any particular climatic zone. Population genetics indexes showed different values within STs and climate zones (π and θ values ranged from 0.004 to 0.147; Nm > 4 and ST from 0.006 to 0.12). Our results show that Blastocystis sp. subtypes exhibit a different genetic variability profile according to the climate zone, suggesting a balancing process between the genetic variability within the Blastocystis sp. subtype and the number of haplotypes identified in each climate.

BACKGROUND: Peritoneal dialysis (PD) is not frequently used in our setting. OBJECTIVE: To analyze the psychological factors involved in the choice of renal replacement therapy (RRT). MATERIAL AND METHODS: A prospective observational study of stable patients without cognitive or sensory deficits who were informed about RRT from January 2004 to July 2006 and agreed to participate. The patients were given and completed the Beck Depression Inventory and the Eysenck personality questionnaire. Clinical and sociodemographic data and RRT choice were recorded. End of follow-up: 2007/10/31. RESULTS: 44 patients were studied: age, 65.4 +/- 13.1 years, 48% male, 34% diabetic. When choosing RRT, 36% of patients had symptoms of depression. Neither depression symptoms nor personality traits were related to the choice of dialysis type. The youngest patients chose PD (41%). After a mean followup of 8 +/- 8 months, 70% of patients started RRT (68% haemodialysis [HD], 32% PD). None of the patients who chose HD changed their mind, but 3 of the 13 patients (23%) who chose PD finally commenced HD, usually in the context of a worsening of the disease. Half of the patients with depression symptoms when choosing PD and a third of the patients with higher levels of neuroticism changed their decision and finally opted for HD. CONCLUSIONS: When choosing RRT, the prevalence of depression symptoms is high. Neither depression nor personality traits influenced the initial choice of RRT, although these factors may be involved in subsequent changes to the decision.

INTRODUCTION: In 2007 the Scientific Quality-technical and Improvement of Quality in Peritoneal Dialysis was edited. It includes several quality indicators. As far as we know, only some groups of work had evaluated these indicators, with inconclusive results. AIM: To study the evolution and impact of guidelines in Peritoneal Dialysis. METHODS: Prospective cohort study of each incident of patients in Peritoneal Dialysis, in a regional public health care system (2003-2006). We prospectively collected baseline clinical and analytical data, technical efficacy, cardiovascular risk, events and deaths, hospital admissions and also prescription data was collected every 6 months. RESULTS: Over a period of 3 years, 490 patients (53.58 years of age; 61.6% males.) Causes of ERC: glomerular 25.5%, diabetes 16%, vascular 12.4%, and interstitial 13.3%. 26.48% were on the list for transplant. Dialysis efficacy: Of the first available results, the residual renal function was 6.37 ml/min, achieving 67.6% of all the objectives K/DOQI. 38.6% remained within the range during the entire first year. Anaemia: 79.3% received erythropoietic stimulating agents and maintained an average Hb of 12.1 g/dl. The percentage of patients in the range (Hb: 11-13 g/dl) improved after a year (58.4% vs 56.3% keeping in the range during this time of 25.6%). Evolution: it has been estimated that per patient-year the risk of: 1) mortality is 0.06 IC 95% [0.04-0.08]; 2) admissions 0.65 [0.58-0.72]; 3) peritoneal infections 0.5 [0.44-0.56]. CONCLUSION: Diabetes Mellitus patients had a higher cardiovascular risk and prevalence of events. The degrees of control during the follow-up in many topics of peritoneal dialysis improve each year; however they are far from the recommended guidelines, especially if they are evaluated throughout the whole study.

OBJECTIVE: To determine the prevalence of relevant drug-drug interactions (DDIs) and associated predictor factors in a sample of patients with multiple complex chronic diseases (polypathological patients) receiving multiple drug therapy. Our secondary objective was to determine the acceptance of a drug interaction reporting program with recommendations addressed to the prescribing physicians. SUBJECTS AND METHODS: A cross-sectional study performed in three primary care centres assigned to a teaching hospital. All patients with 2 or more chronic diseases and treated simultaneously with 5 or more drugs were recruited in the study. DDIs were detected by using Drug-Reax System((R)) (Micromedex) program, the Drug Data Base (Bot) Spanish General Council of Official Colleges of Pharmacists or literature search when needed. Those DDIs which, according to the opinion of the pharmacist investigators, required any intervention were considered relevant. Acceptance of the reported DDI recommendations was evaluated by means of a survey addressed by primary care physicians ("acceptable," pertinent recommendation to modify treatment). RESULTS: A total of 283 polypathological polymedicated patients were included. Mean age was 74.5 years (range 43-100 years). Mean number of diseases per patient was 2.5 and prescriptions 9.7). Out of a total of 2748 drug prescriptions, 1053 DDIs in 250 patients (96.5%) were identified. Of these, 45% were filtered as relevant DDIs. The presence of ischemic heart disease, two or more hospital admissions and having received 7 or more prescriptions were associated with the presence of DDIs. 177 informs containing 473 recommendations about DDIs were sent to primary care physicians from our Pharmacy Department. 339 recommendations were answered by primary care physicians, and 84% were favourably accepted. CONCLUSIONS: Almost every polypathological polymedicated patient is exposed to at least one DDI and about a 60% would require any intervention. Appropriate filtering and personalising recommendations in a collaborative way may represent an adequate manner to improve the risk-benefit ratio of the drug prescriptions.

INTRODUCTION: Hip fracture in the elderly is one of the most prevalent diagnoses in Orthopedic Surgery Departments. It has a great impact in medical, economic and social terms. Our objective is to analyze clinical impact of a co-management care model between orthopedic surgery and internal medicine departments for elderly patients admitted with hip fracture in a tertiary referral hospital. MATERIAL AND METHODS: Retrospective cohort study of patients older than 65 years old admitted with hip fracture between January 2005-August 2006 (HIST cohort) without a co-management care model, and between January 2008-August 2010 (COFRAC cohort) with a co-manEdadment care model. Analysis of demographic, clinical and surgery characteristics, complications incidence and mortality and re-admissions at 30 days was made. RESULTS: A total of 701 patients were included (471 HIST, 230 COFRAC). There were no differences in sex, gender, time to surgery, type of anesthesia and surgery, length of stay, ambulation at discharge and 30-days emergency room consultation, readmissions or mortality at 30 days. There were differences in identification of polypatological patients (16.8 vs. 24.4%, P=0.02), presence of osteoporosis (3.9 vs. 7.6%, P=0.03), motor deficit (3.5 vs. 8.8%, P=0.03), number of chronic drugs (3.7±2.5 vs. 4.3±3.2, P<0.01), diagnosis of delirium (15.6 vs. 20.9%, P=0.048), constipation (80.3 vs. 74.7%, p<0.001), monitoring of anemia (83.3 vs. 97.1%, P>0.01) and renal failure at discharge (44.5 vs. 97.3%, P<0.01) and hospital mortality (4.6 vs. 1.3%, P=0.02). CONCLUSIONS: Co-management for elderly patients admitted with hip fracture provides a better information about previously chronic conditions, a higher control of hospital complications and decreases hospital mortality.
RESUMEN
We report an experimental study of the temporal and spatial dynamics of shock waves, cavitation bubbles, and sound waves generated in water during laser shock processing by single Nd:YAG laser pulses of nanosecond duration. A fast ICCD camera (2 ns gate time) was employed to record false schlieren photographs, schlieren photographs, and Mach-Zehnder interferograms of the zone surrounding the laser spot site on the target, an aluminum alloy sample. We recorded hemispherical shock fronts, cylindrical shock fronts, plane shock fronts, cavitation bubbles, and phase disturbance tracks.
RESUMEN
AIM: To describe the characteristics, practice patterns, targets and outcome of the Type 2 diabetic patients (DM 2) in peritoneal dialysis (PD) and to compare them with non-diabetic ones. METHODS: Prospective cohort study of every incident PD patient in a regional public health care system (2003-2006). We prospectively collected baseline data, hospital admissions, peritonitis, transplants, CV events and deaths. Every six months PD prescription data and results on efficacy, anaemia, blood pressure (BP) were collected. RESULTS: DM 2 patients (n = 65) were older and presented a higher rate of previous CV events (60.9% vs. 17.7% p<0001) than non-DM patients (n = 376) and worse BP control at inclusion on PD. There were no differences in dialysis efficacy targets and anaemia management. HOSPITAL ADMISSIONS: DM 2 patients present higher hospitalisation rates 1.1 [0.9-1.4] than NoDM ones 0.6 [0.5-0.7] admissions per year at risk. Survival: DM 2 patients present lower PD-technique survival than No DM ones (870 vs. 1002 days Kaplan-Mayer estimation p = 0.009) and higher annual mortality rate (13.7 vs. 4.1%, p: 0.021) with a crude mortality hazard ratio (HR) of 2.5 [1.1-5.6] after correction by age. However, the best predictive model for mortality by Cox proportional hazards model includes age, existence of previous CV events and forced inclusion on PD and excludes DM 2. The association between DM 2 and CV events ruled out DM 2 from the multivariate risk model. CONCLUSION: Type 2 DM patients had a higher prevalence of previous CV events, and a worse global outcome. Previous CV events may explain part of this risk.

A technique has been developed for fabrication of ultrahydrophobic Ti-6Al-4V surface by vacuum process. This report has the data related to the article "Hybrid laser and vacuum process for rapid ultrahydrophobic Ti-6Al-4â¯V surface formation" on the fabrication of ultrahydrophobic Ti-6Al-4V by Vacuum process (Jagdheesh et al., 2019). The present data consist of X-ray photo electron spectroscopy spectrums recorded for the laser patterned ultrahydrophobic samples, droplet image and surface chemical composition of laser patterned Ti-6Al-4V samples before vacuum process(b. v. p.) and after vacuum process (a. v. p.) for 120â¯min. The presented data give a clear idea about the chemical modification evolved during the vacuum process.
RESUMEN
The purpose of this study was to determine if different methods for average bioequivalence in high variability drugs coincide or not in their conclusions when applied to the same dataset, and to discuss the method validity and reliability of the conclusions. Different approaches for the evaluation of average bioequivalence were applied to the results of a bioavailability trial on the diuretic drug Furosemide. These methods included widening the bioequivalence limits according to regulatory recommendations, scaling the limits and scaling the bioequivalence statistic, jointly with evaluating alternative bioavailability measures. The methods to establish the bioequivalence limits were also combined with some alternative methods to construct confidence intervals. The decision on bioequivalence depends much more on the bioavailability measures than on the statistical approach. The reliability of the final decision lies mainly in the interpretation of these measures and on the special characteristics of each drug.

According to previous reviews, hemoperitoneum episodes appear in 6.1-8.4% of the peritoneal dialysis patients, and they are severe in a 20% of them. Due to the absence of severe hemoperitoneum in our peritoneal dialysis program, we retrospectively reviewed hemoperitoneum non-related with abdominal surgery or catheter placing. We analyzed its incidence, etiology, prognostic and clinical outcome, as well as the possible effect of recurrent hemoperitoneum on peritoneal function. A total of 132 patients were treated in our centre during a period of 173 months. Mean age at the beginning of peritoneal dialysis was 59+/-17.1 years, 43.2% were females, and 22.8% of them were menstruating women. Twenty-two patients had at least one hemoperitoneum episode during follow-up, with an incidence of 17%. The mean time interval between the start of peritoneal dialysis and the first hemoperitoneum episode was 0.66+/-0.94 years (range: 0.01-3.20 years). 73% were women. Most cases (59%) were due to menstruation. Remarkably, all the menstruating women presented hemoperitoneum at least once with a high incidence of recurrent episodes. The other hemoperitoneum episodes were mainly of unknown etiology (32% of patients), being this one the main cause in males. We only observed two more cases: a male who presented hemoperitoneum related to dicumarinic overdose and a female who presented hemoperitoneum due to mesenteric ischemia. All the 22 patients had a favourable outcome, except for the woman with mesenteric ischemia, what represented an incidence of 4.5% of severe hemoperitoneum. No significant association was found between episodes of hemoperitoneum and aspirin treatment, dicumarinic treatment or the presence of coagulopathy. There was no association either between recurrent hemoperitoneum and the number of peritonitis episodes, peritoneal function or technique survival. In conclusion, hemoperitoneum is a common and usually benign problem in peritoneal dialysis patients, frequently due to retrograde menstruation, and no deleterious long-term effects were found in patients with recurrent hemoperitoneum.

We have fabricated and characterized a lattice of submicron cone-shaped holes on a SiO(2)/Si wafer. Reflectivity profiles as a function of angle of incidence and polarization, phase shift and spectrometry are obtained for several fluids with different refractive indexes filling the holes. The optical setup allows measuring in the center of a single hole and collecting all data simultaneously, which can be applied for measuring extremely low volumes of fluid (in the order of 0.1 femtolitres) and label-free immunoassays, as it works as a refractive index sensor. A three layer film stack model is defined to perform theoretical calculations.
RESUMEN
Multivariate calibration methods (partial least squares calibration, back propagation multilayer perceptrons networks, radial basis functions and generalized regression neural networks) were applied to the simultaneous fluorometric quantification of levofloxacin, garenoxacin and grepafloxacin, without previous separation steps. A data matrix was obtained by registering the emission spectra of mixtures of the three quinolones in urine (with concentrations ranging over 0.00-0.40 microg mL-1 for each quinolone) with a 283 nm excitation at pH 4.0. The generalized regression neural network model proved to be the most adequate model for simultaneous quantification of the three quinolones in urine samples.

BACKGROUND AND OBJECTIVE: Knowledge of the life-sustaining treatment preferences of the dialysis patients would be extremely helpful to substitute decision-makers and nephrologists in deciding whether to continue or stop a treatment. The population of the Mediterranean countries show this opinion with less frequency. The objective of this study is: 1) the knowledge of the patient's view for the advance directives; it may increase the likelihood to get the correct decisions of the staff when complications break the normal course of chronic dialysis, and 2) the statement of the advance directives. MATERIAL AND METHOD: We distributed 135 questionnaires to patients with chronic renal failure in dialysis treatment of the Sabadell's Hospital to explore demographic information about responders and not-responders and explore the rate of questionnaires was completed about the cardiopulmonary resuscitation, respirator, tube feeding and dialysis in case of coma, persistent vegetative state, severe dementia and terminal illness. We explore about the representative of patients and in case of not-responders about the cause to not answer. RESULTS: Sixty-four of 135 patients (47,8%) did not want cardiopulmonary resuscitation, respirator, tube feeding or dialysis in case of coma, persistent vegetative state, severe dementia or terminal illness. Compared with patients who wanted the treatments, those who did not were older (71,2 versus 62,2 years; p = 0.002). There was no difference in the other demographic questions, including sex (p=0.674), cause of kidney failure (p=0.815), comorbid conditions (p=0.824), and social status (language of questionnaire -0.155- and standard of education -0.288-). Advance care planning does not occur solely within the context of the physician-patient relationship; the respondents reported the representative in the family, essentially. The patients not-responders doesn t want to think in those situations and also they show doubt about the interpretation of their answers. CONCLUSIONS: near 50% patients in chronic dialysis want to stop certain treatments in case of resuscitation cardiopulmonary, coma, persistent vegetative state, severe dementia or terminal illness. The older patients want the limitation of treatments more frequently.

BACKGROUND: The incidence of chronic renal failure increase with the age. The selection of patient to dialysis has been increasing in spite of the high comorbidity. Moreover, in our clinical practice the aged patient is not contraindicated to dialysis. However, in the nephrology clinical practice not all the patients start the treatment with dialysis. OBJECTIVE The aim of our study has been to compare the characteristics of the patients who had not been dialyzed between the periods 1992-1995 and 2000-2003 to analyze the trend of the nephrology clinical practice. MATERIAL AND METHODS: Comparative study of the characteristics and the evolution of patients with chronic renal failure in stage V, (renal failure) not incorporated to dialysis in one hospital during four years between the periods the 1992-1995 ( period A) and 2000-2003 (period B). RESULTS: Start dialysis (period A versus period B): 116 patients, age 59.9+15.5 years vs. 229 patients, age 64.0+15.8 years (p<0.05). Non-dialysis (period A versus period B): 38 patients, age 77.5+9.3 years vs. 37 patients, age 81.7+6.2 years (p<0.01). Renal function: serum creatinina 7.4+2.4 mg/dl vs. 5.3+1.2 mg/dl (p<0.001), MDRD estimate glomerular filtration 6.9+2.4 mg/dl ml/min/1.73 m2 vs. 10.0+2.3 ml/min/1.73 m2 (p<0.001). Primary renal disease: unknown etiology 31.5 % vs. 24.3 %, nephroangiosclerosis 23.6 % vs. 32.4 %, diabetes 28.9 % vs. 21.6 %. Functional status: dependent patients 34.2 % vs 83.8 % (p<0.001). The principal reason for non-dialysis were: personal decision: 26.3 % vs. 35.1 %, dementia 15.8 % vs. 29.7 %, brief life expectancy because of serious co-existing diseases 13.1 % vs. 21.7 % and serious chronic illness with inability for themselves care 44.7 % vs. 13.1 %. Comorbid conditions: 2.3+1.0 vs. 3.0+1.5 (p<0.05). Survival: 55+168 days vs. 168+236 days (p<0.001). CONCLUSION: Most of the patients that don't begin dialysis are elderly together with a poor functional capacity and with more autonomy in their decisions. The identification of patients with renal failure (stage V) was detected early in the last period than in the following one. The conservative management of non-dialyzed uremic patients is a significative nephrology clinical practice due to more survival of those persons.
