Objectives: To describe the proportion of patients with liver fibrosis in at-risk populations in primary care (PC). To know the agreement between FIB-4 and transitional elastography (TE), interobserver agreement between PC and hospital care (HC) in TE, and associated risk Factors (RF)., Methods: Observational, descriptive, cross-sectional study in ≥16 years of age with RF for chronic liver disease. Sex and age, RF (alteration of liver tests [LT], metabolic syndrome, diabetes, obesity, alcohol consumption, hepatic steatosis), and FIB-4, controlled attenuation parameter and TE in PC and in HC, were collected. According to a consensus algorithm, vibration-controlled TE was performed in PC in patients with FIB-4≥1,3, and those with measurement ≥8kPa were referred to HC., Results: 326 patients were studied. 71% were not referred to HC, due to liver stiffness <8kPa. 83 of the 95 derivations did TE in HC. 45 (54%) had TE ≥8, and 25 (30%) ≥12. The proportion of patients with stiffness ≥8kPa was 13,8% (45/326) and ≥12kPa, 7,6% (25/326). The predictive values of the FIB-4 were low. The interobserver correlation coefficient between TE in PC and HC was 0,433. Variables associated with TE ≥8 in PC: LT alteration, diabetes and steatosis. With TE ≥12: LT alteration, diabetes and obesity., Predictor Variables: LT alteration and obesity., Conclusions: The study supports the sequential performance of serum indices and TE as a screening for fibrosis in the at-risk population in PC, which allows a reduction in the percentage of patients referred to AH, and a better stratification of risk patients., (Copyright © 2024 Elsevier España, S.L.U.

Background and Objective: The older we get, the greater the production of reactive oxygen species and therefore the greater the oxidative stress, which is related to the deterioration of the health of older adults. This study analyzed the relationship between the oxidative profile and the dietary diversity index in an urban-marginal population of older adults in Costa Rica., Methods: Eighty-eight older adults were studied and various markers of oxidative stress, serum glucose levels, lipid profile, and some micronutrients were determined. In addition, the body mass index (BMI) was calculated and the dietary diversity index (DDI) was determined., Results: Lipid peroxidation and DNA oxidation, a mean plasma antioxidant capacity percentage of 39.54±10.67%, which decreased with age, were evidenced. 67% of the participants had alterations in glycemia, 73% had one or more alterations in blood lipid levels, 55% had insufficient vitamin D levels, and 68.6% were overweight. The average IDD was 4.91 points, indicating that the diet was not very diverse. No relationship was found between IDD and nutritional status, between nutritional status and oxidative stress, nor between biochemical variables and oxidative stress., Conclusion: The adults studied presented high oxidative stress, a high percentage of overweight, and a low IDD. A higher IDD was associated with a lower blood concentration of MDA and a higher % PAC., (Copyright © 2023 SEGG. Publicado por Elsevier España, S.L.U. All rights reserved.)

Objective: To describe the baseline characteristics, clinical presentation, imaging tests and outcomes, and identify potential prognostic factors in a cohort of patients diagnosed with cerebral venous thrombosis (CVT)., Patients and Methods: This retrospective, single-center, observational study included adult patients diagnosed with CVT from January 2016 to December 2020. The variables were reviewed using electronic medical records., Results: A total of 35 patients were included, with a median age at diagnosis of 50.3 (+/- 17.8) years, and the majority being women (74.4%). Nearly 95% of the patients presented at least one risk factor for the development of CVT. Heparins were used for the acute phase in 97.1% of cases, with 75% of those being low molecular weight heparins.During the first two weeks, a compound event (death, intensive care unit admission, National Institute of Health Stroke Scale at discharge >3, CVT recurrence, major bleeding, or the presence of complications) occurred in 28.6% of patients (10 patients).Over the mean follow-up period of 3.3 years, 14.3% of the patients died (with only one death attributed to CVT), one patient experienced major bleeding, and no patients had a recurrence of CVT., Conclusions: In our cohort, CVT predominantly affected young women with at least one risk factor for its development. The presence of edema on CT and corticosteroid treatment were associated with a poor short-term prognosis. However, we observed a favorable long-term prognosis in terms of mortality, recurrence, and bleeding., (Copyright © 2023 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI).

Introduction: The presence of stones in the urinary tract is a condition that has accompanied humans since ancient times. In colonial times, this condition was known as "stone pain" and its non-surgical management was based on the use of medicines derived from plants, animals and minerals., Objective: To contextualize a medical prescription used to modulate stone pain in the 18th century in the New Kingdom of Granada. Additionally, to analyze its components and evaluate the basis of its possible phytotherapeutic effects on the disease and pain., Material and Method: Document search in the Cipriano Rodríguez Santamaría Historical Archive of the Octavio Arizmendi Posada Library at Universidad de La Sabana. The document entitled "Prescription for bladder or kidney stone pain" was analyzed, and a complementary review of current scientific literature and original texts was performed with no time limits, in order to compare this prescription to related findings in the history of medicine., Results: The transcription of the source document revealed several phytotherapeutic agents such as chamomile (Matricaria recutita), lilies (Lilium lancifolium), clover (Trifolium pratense), and mallow roots (Malva sylvestris), accompanied by a large amounts of water., Conclusions: There is scientific evidence that could explain the anti-inflammatory and antioxidant effects of all plant-derived medicines used in this prescription. Abundant water intake to increase urine volume was an essential part of treatment. However, the lack of more precise data related to the prescription and the evolution of the patients makes it difficult to analyze its therapeutic efficacy., (Copyright © 2020 AEU.

Introduction: Haemophilus influenzae is a cause of mild and severe invasive infections, especially among children under 5 years old. Serotype b (Hib) was very frequent before the introduction of the vaccine, which was introduced in Paraguay in 2004., Methods: A total of 523 isolates of H. influenzae obtained from 1999 to 2017 and referred to the National Reference Laboratory in Paraguay were studied by conventional microbiological methods and molecular techniques., Results: The most frequent serotype was non-typeable (HiNT) (51.8%; 271/523), followed by Hib (43%; 225/523), Hia and Hif (1.5%; 8/523, respectively), Hic (1%; 5/523), Hie (0.8%; 4/523), and Hid (0.4%; 2/523). A total of 48.4% invasive infections were caused by HiNT, and 46.1% by Hib; 88.6% of isolates corresponded to meningitis, 70.8% to sepsis and 50.9% to pneumonia in children under 5 years. A total of 84% (181/217) of isolates corresponded to invasive infections caused by Hib in children under 5 years, with the highest proportion observed between 2001 and 2003. The most prevalent biotypes were biotype I (29%), biotype II (12%), biotype III (24%), and biotype IV (13%). Among the total of isolates, 13% (68/523) of isolates were resistant to ampicillin., Conclusion: After the introduction of the Hib vaccine in Paraguay, the number of invasive Hib cases decreased in children under 5 years old, although we observed an increase of HiNT in children over 5 years. Continuous surveillance is necessary in order to monitor the effectiveness of the vaccine and for the development of preventive interventions., (Copyright © 2020 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Background: Rapid sequence induction (RSI) in adults has undergone changes in recent years due to pharmacological and technological advances. The objective of this survey was to evaluate current practice among Spanish anesthesiologists., Methods: A 31-item questionnaire regarding RSI practice was sent to anesthesiologists working in Spanish public hospitals. Differences in responses according to the type of hospital or experience of the respondent were compared for all data using the chi-square and Fisher's exact test., Results: Approximately 15.89% of Spanish anesthesiologists participated in the survey (1002 questionnaires). The results show considerable heterogeneity in most aspects of RSI. Less than 20% of respondents administer sodium citrate. Sixty-four percent place a nasogastric tube in patients with intestinal obstruction. Gastric residue is assessed by ultrasound in 6% of cases. Only 25% of respondents measure ETO 2 to check the effectiveness of preoxygenation, and 22% use nasal oxygen insufflation with nasal prongs or THRIVE. Sixty two percent of respondents apply cricoid pressure, but only 50% release the pressure when encountering intubation difficulty. Up to 40% of respondents reported cases of aspiration despite applying cricoid pressure. Propofol was the most commonly used hypnotic (97.6%), but there was no clear preference in the choice of neuromuscular relaxant (suxamethonium versus rocuronium ratio of approximately 1:1). Only 44% of respondents calculated the dose of sugammadex that would be required for emergency reversal of rocuronium., Conclusions: The survey showed significant variation in RSI practice, similar to that of other countries. Quality prospective studies are needed to standardize clinical practice., (Copyright © 2020 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

Introduction: Risk management and patient safety are closely related, following this premise some industries have adopted measures to omit number 13. Healthcare is not left behind, in some hospital the day of surgery's or bed numbering avoid number 13. The objective was to assess whether it is necessary to redesign the safety policies implemented in hospitals based on avoiding 13 in the numbering of rooms/beds., Methods: A retrospective cohort study was conducted. Mortality and the number of adverse events suffered by patients admitted to rooms/beds numbering 13 (bad chance) or 7 (fair chance) over a two-year period to Intensive Care Unit, Medicine, Gastroenterology, Surgery, and Paediatric service were registered and compared., Results: A total of 8553 admissions were included. They had similar length-of-stay and Charlson Index scores (p-value=0.435). Mortality of bed 13 was 268 (6.2%, 95% CI 5.5-6.9) and 282 in bed 7 (6.7%, 95% CI 5.9-7.5) (p-value=0.3). A total of 422 adverse events from 4342 admissions (9.7%, 95% CI 8.9-10.6) occurred in bed 13, while in bed 7 the count of adverse events was 398 in 4211 admissions (9.4%, 95% CI 8.6-10.4) (p-value=0.6). Odds Ratio for mortality was equal to 0.9 (95% CI 0.8-1.1) and suffering adverse events when admitted to bed 13 versus bed 7 was 1.03 (95% CI 0.9-1.2)., Conclusions: Bed 13 is not a risk factor for patient safety. Hospitals should pay attention to causes and interventions to avoid adverse events based on evidence rather than beliefs or myths., (Copyright © 2020 FECA. Publicado por Elsevier España, S.L.U.

Objective: The aim of this study was to stratify medications used in hospital  care according to their potential risk., Method: The RAND/UCLA Appropriateness Method was used. Anatomical Therapeutic Chemical subgroups were classified according to their potential risk. A literature search, bulletins, and alerts issued by patient safety organizations were used to identify the potential safety risk of  these subgroups. Nine experts in patient/medication safety were selected to score the subgroups for their appropriateness in the classification. Two evaluation rounds were conducted: the first by email and the second by a  panel meeting., Results: A total of 298 Anatomical Therapeutic Chemical subgroups were  evaluated. They were classified into three scenarios (low, medium, and high  risk). In the first round, 266 subgroups were classified as appropriate to the  assigned scenario, 32 were classified as uncertain, and none were classified as  inappropriate. In the second round, all subgroups were classified as appropriate.  The most frequent subgroups in the low-risk scenario belonged to  group A "Alimentary tract and metabolism" (44%); the most frequent in the  medium-risk scenario belonged to group J "Antiinfectives for systemic use"  (32%); and the most frequent in the high-risk scenario belonged to group L  "Antineoplastic and immunomodulating agents" (29%) and group N "Nervous  system" (26%)., Conclusions: Based on the RAND/UCLA appropriateness method, Anatomical  Therapeutic Chemical subgroups used in hospital care were classified according  to their potential risk (low, medium, or high). These lists can be incorporated  into a risk-scoring tool for future patient/medication safety studies., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.)

The need to reduce the time it takes to establish a microbiological diagnosis and the emergence of new molecular microbiology and proteomic technologies has fuelled the development of rapid and point-of-care techniques, as well as the so-called point-of-care laboratories. These laboratories are responsible for conducting both techniques partially to response to the outsourcing of the conventional hospital laboratories. Their introduction has not always been accompanied with economic studies that address their cost-effectiveness, cost-benefit and cost-utility, but rather tend to be limited to the unit price of the test. The latter, influenced by the purchase procedure, does not usually have a regulated reference value in the same way that medicines do. The cost-effectiveness studies that have recently been conducted on mass spectrometry in the diagnosis of bacteraemia and the use of antimicrobials have had the greatest clinical impact and may act as a model for future economic studies on rapid and point-of-care tests., (Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Most cytostatic drugs cannot be administered directly to patients in their marketed presentation, but require previous reconstitution conducted in the Pharmacy Unit areas for cytostatic preparation. There are systems that allow drug reconstitution and transfer once it has been diluted, in order to protect staff from any potential contamination during handling. These are commonly known as Closed Systems, and generally have a piece for vial attachment and a syringe adapter with a built-in filter, that replace the traditional needles. Closed systems feature different characteristics and costs which is necessary to analyze in order to determine the most efficient one., (Copyright AULA MEDICA EDICIONES 2014.

In general, new technologies usually increase laboratory costs due to the need for an initial investment. However, as occurred with MALDI-TOF (matrix-assisted laser desorption ionization time-of-flight) mass spectrometry, this increase is subsequently offset by the discontinued use of traditional technologies and by the benefits to patients of the new information generated. In the clinical microbiology laboratory, the identification time is reduced with the use of MALDI-TOF (by at least 24 hours) and turnaround is improved, allowing faster production of the microbiological report. This beneficial effect has mainly been studied with blood cultures in patients with bacteraemia. In these patients, the length of hospital stay has been reduced by 1.6-6.6 days, depending on the type of patient and the appropriateness of treatment. This leads to better antimicrobial use and a reduction in total hospital cost of up to 43% per patient. Another factor that has been analysed is the decrease in mortality due to better management of antimicrobial therapy. Future multicentre studies should include other factors such as hospital organisation changes and clinical activity arising in response to the efforts of the clinical microbiology laboratory to rapidly obtain information of clinical value., (Copyright © 2016 Elsevier España, S.L.U.

Objective: An evaluation is made of the hospital mortality predicting capacity of the main predictive scoring systems., Design: A 2-year retrospective cohort study was carried out., Setting: A third level ICU with surgical and medical patients., Patients: All patients with multiorgan failure during the first day in the ICU., Main Variables: APACHE II and IV, SAPS II and III, MPM II and hospital mortality., Results: A total of 568 patients were included. Mortality rate: 39.8% (226 patients). Discrimination (area under the ROC curve; 95% CI): APACHE IV (0.805; 0.751-0.858), SAPS II (0.755; 0.697-0.814), MPM II (0.748; 0.688-0.809), SAPS III (0.737; 0.675-0.799) and APACHE II (0.699; 0.633-0.765). MPM II showed the best calibration, followed by SAPS III. APACHE II, SAPS II and APACHE IV showed very poor calibration. Standard mortality ratio (95% CI): APACHE IV 1.9 (1.78-2.02); APACHE II 1.1 (1.07-1.13); SAPS III 1.1 (1.06-1.14); SAPS II 1.03 (1.01-1.05); MPM 0.9 (0.86-0.94)., Conclusions: APACHE IV showed the best discrimination, with poor calibration. MPM II showed good discrimination and the best calibration. SAPS II, in turn, showed the second best discrimination, with poor calibration. The APACHE II calibration and discrimination values currently disadvise its use. SAPS III showed good calibration with modest discrimination. Future studies at regional or national level and in certain critically ill populations are needed., (Copyright © 2015 Elsevier España, S.L.U. and SEMICYUC. All rights reserved.)

The normal activity in the laboratory of microbiology poses different risks - mainly biological - that can affect the health of their workers, visitors and the community. Routine health examinations (surveillance and prevention), individual awareness of self-protection, hazard identification and risk assessment of laboratory procedures, the adoption of appropriate containment measures, and the use of conscientious microbiological techniques allow laboratory to be a safe place, as records of laboratory-acquired infections and accidents show. Training and information are the cornerstones for designing a comprehensive safety plan for the laboratory. In this article, the basic concepts and the theoretical background on laboratory safety are reviewed, including the main legal regulations. Moreover, practical guidelines are presented for each laboratory to design its own safety plan according its own particular characteristics., (Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Objective: To assess the response of patients diagnosed with painful bladder syndrome to treatment with instillations of sodium chondroitin sulfate., Material and Methods: We present a series of cases of patients with painful bladder syndrome who followed a bladder instillation protocol with sodium chondroitin sulfate, according to our centre's regimen. The response to treatment was assessed with respect to pain, according to the Downie scale; urinary frequency, according to the voiding diary; and subjective improvement, according to the Patient Global Impression of Improvement (PGI-I) scale., Results: A total of 28 patients with a median age of 59 years (range 22-90) followed this protocol. From the medical histories, 19.4% had suffered an infection of the urinary tract, 3.8% had suffered urinary tuberculosis, 7.6% received pelvic radiation therapy and 26.9% had taken anticholinergic drugs for overactive bladder syndrome. We evaluated the response to treatment at 0, 3, 6 and 12 months and found that at the end of treatment 72.3% of the patients had improved bladder pain and 75% were significantly better., Conclusions: Treatment with sodium chondroitin sulfate through endovesical instillation in painful bladder syndrome improves pain, voiding frequency and quality of life in the long term., (Copyright © 2013 AEU.

Effective communication skills form part of being a good doctor. Today there is solid evidence to support the teaching of effective communication skills in all medical schools. This article describes how communication is different from the other skills that medical students and residents need to learn, how this affects teaching and learning, and the application of these ideas in a Chilean medical school. We describe the premises that need to be taken into consideration when planning teaching communication in medicine and illustrate how these affected the development of our teaching of communication in our undergraduate curriculum. All medical education programmes should include formal teaching on the doctor-patient relationship, but must take into consideration the aspects of communication teaching that make it different from teaching other aspects of medicine., (Copyright © 2010 Elsevier España, S.L.

Introduction: The objective of the present work is to describe our experience in the surgery of the ureter and bladder in patients with primary and recurrent ovarian cancer subjected to peritonectomy procedures and the administration of hyperthermic intraoperative intraperitoneal chemotherapy (HIIC)., Patients and Method: Those patients who required surgical procedures on the distal ureter or bladder, were selected from a prospective data base constructed at the beginning of the peritoneal carcinomatosis program in our centre. Seven patients fulfilled this requirement and were included in the study. A total of 81 patients diagnosed with primary or recurrent ovarian cancer from December 2007 to April 2011 were included for maximum effort cytoreduction and HIIC., Results: It was necessary to perform some surgical manoeuvre on the ureter or bladder in seven patients, with a median age of 46 years (40-71). Four patients were operated on due to recurrence of the ovarian disease and in the other 3 patients the indication was surgical rescue after non-optimal surgery in another centre. There was direct tumour involvement of the lower urinary tract in 4 of them. Three patients (42%) in the series developed at least one postoperative complication., Conclusion: The performing of peritonectomy procedures that include the eventual resection of the ureter or bladder, and the subsequent application of HIIC in a selected group of patients with peritoneal dissemination due to an ovarian carcinoma can be done with reasonable rates of postoperative morbidity. These surgical procedures may be necessary to achieve optimal surgery., (Copyright © 2011 AEC. Published by Elsevier Espana. All rights reserved.)

Pathogenic bronchopulmonary colonizations and the exacerbations produced are among the most important causes of reduced pulmonary function in patients with bronchiectasis. The most frequent pathogens in these patients are Haemophilus influenzae and Pseudomonas aeruginosa. Lesions are produced by the local inflammatory process and the vicious circle developed by antigen stimulation, the release of inflammatory mediators, the presence of neutrophils, the increase of bacterial inoculum and the release of bacterial exoproducts. P. aeruginosa has been demonstrated to affect the patients with bronchiectasis and poorest quality of life and to colonize those with the poorest pulmonary function and the highest number of antimicrobial treatments. In bronchiectasis, as in chronic obstructive pulmonary disease (COPD) or cystic fibrosis, P. aeruginosa is able to colonize the respiratory mucosa chronically. Due to the ecological niche occupied by P. aeruginosa and the multitude of cycles with antimicrobial agents to which these patients are subjected, the development of antimicrobial resistance is highly likely, encouraged by the high proportion of hypermutation variants in existence. Likewise, P. aeruginosa naturally grows in the form of biofilms on the mucosal surface, greatly contributing to its persistence. Antimicrobial treatment in patients with bronchiectasis and P. aeruginosa colonization should be based on antimicrobial agents, alone or in combination, that do not lose activity when acting on biofilms., (Copyright © 2011 Sociedad Española de Neumología y Cirugía Torácica.

We report the case of a female patient who was diagnosed with Vogt-Koyanagi-Harada disease at the age of 14 years and who developed myelopathy, resulting in paraparesis. A cerebral magnetic resonance imaging scan revealed the presence of T2-hyperintense lesions in the periventricular white matter, suggesting demyelinization. Twelve years later, ulcerative colitis was diagnosed during workup for abdominal pain associated with bloody diarrhea. The association of these two diseases has previously been reported anecdotically. The management of the ulcerative colitis was complicated by the patient's neurological manifestations. Even though recent reports support the use of anti-TNF drugs in the management of Vogt-Koyanagi-Harada-associated uveitis, because of the lack of experience in patients with neurological symptoms, and the presence of apparently demyelinating lesions in our patient, we did not use these drugs in this case.
