[Recommendations for the management of critically ill patients with COVID-19 in Intensive Care Units]. / Recomendaciones para el manejo de los pacientes críticos con COVID-19 en las Unidades de Cuidados Intensivos.

The COVID-19 pandemic has led to the admission of a high number of patients to the ICU, generally due to severe respiratory failure. Since the appearance of the first cases of SARS-CoV-2 infection, at the end of 2019, in China, a huge number of treatment recommendations for this entity have been published, not always supported by sufficient scientific evidence or with methodological rigor necessary. Thanks to the efforts of different groups of researchers, we currently have the results of clinical trials, and other types of studies, of higher quality. We consider it necessary to create a document that includes recommendations that collect this evidence regarding the diagnosis and treatment of COVID-19, but also aspects that other guidelines have not considered and that we consider essential in the management of critical patients with COVID-19. For this, a drafting committee has been created, made up of members of the SEMICYUC Working Groups more directly related to different specific aspects of the management of these patients.

Long-term predictors of residual or recurrent cervical intraepithelial neoplasia 2-3 after treatment with a large loop excision of the transformation zone: a retrospective study.

OBJECTIVE: To assess the long-term risk factors predicting residual/recurrent cervical intraepithelial neoplasia (CIN 2-3) and time to recurrence after large loop excision of the transformation zone (LLETZ). DESIGN: Retrospective study. SETTING: Colposcopy clinic. POPULATION: 242 women with CIN 2-3 treated between 1996 and 2006 and followed up until June 2016. METHODS: Age, margins, and high-risk human papillomavirus (HR-HPV) were estimated using Cox proportional hazard and unconditional logistic regression models. The cumulative probability of treatment failure was estimated by Kaplan-Meier analysis. MAIN OUTCOME MEASURE: Histologically confirmed CIN 2-3, HR-HPV, margins, age. RESULTS: CIN 2-3 was associated with HR-HPV (HR = 30.5, 95% confidence interval [CI] = 3.80-246.20), age >35 years (HR = 5.53, 95% CI = 1.22-25.13), and margins (HR = 7.31, 95% CI = 1.60-33.44). HR-HPV showed a sensitivity of 88.8% and a specificity of 80%. Ecto+ /endocervical+ (16.7%), uncertain (19.4%) and ecto- /endocervical+ margins (9.1%) showed a higher risk of recurrence (odds ratio [OR] = 13.20, 95% CI = 1.02-170.96; OR = 15.84, 95% CI = 3.02-83.01; and OR = 6.60, 95% CI = 0.88-49.53, respectively). Women with involved margins and/or who were HR-HPV positive had more treatment failure than those who were HR-HPV negative or had clear margins (P-log-rank <0.001). CONCLUSIONS: HR-HPV and margins seem essential for stratifying post-LLETZ risk, and enable personalised management. Given that clear margins present a lower risk, a large excision may be indicated in older women to reduce the risk. TWEETABLE ABSTRACT: After LLETZ for CIN 2-3, recurrences appear more often in women with positive HR-HPV and involved margins and aged over 35.

Molecular identification of zoonotic hookworm species in dog faeces from Tanzania.

The presence and distribution of various species of canine hookworms in Africa are poorly known. The main objective of this study, therefore, was to identify the hookworm species present in canine faecal samples from Morogoro, Tanzania, using molecular techniques. Faecal samples from 160 local dogs were collected and hookworm positive samples processed to recover larvae for further molecular characterization. DNA was extracted from pools of larvae from individual samples (n = 66), which were analysed subsequently using two different molecular approaches, polymerase chain reaction-linked restriction fragment length polymorphism (PCR-RFLP) and species-specific PCR coupled with Sanger sequencing. The PCR-RFLP technique detected only the presence of the ubiquitous Ancylostoma caninum in the 66 samples. However, by species-specific PCR coupled with Sanger sequencing we identified ten samples with A. braziliense, two with Uncinaria stenocephala and five with A. ceylanicum. Thus, all four known species of canine hookworms were identified in Morogoro, Tanzania. To our knowledge this is the first report of the detection of the presence of U. stenocephala and A. ceylanicum in Africa using molecular techniques. In addition to their veterinary importance, canine hookworms have zoonotic potential and are of public health concern.

Apps and intensive care medicine. / Apps y Medicina Intensiva.

Technological advances have played a key role over the last century in the development of humankind. Critical Care Medicine is one of the greatest examples of this revolution. Smartphones with multiple sensors constitute another step forward, and have led to the development of apps for use by both professionals and patients. We discuss their main medical applications in the field of Critical Care Medicine.

Recommendations of the Working Groups from the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) for the management of adult critically ill patients. / Recomendaciones para el tratamiento de los pacientes críticos de los Grupos de Trabajo de la Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias (SEMICYUC).

The standardization of the Intensive Care Medicine may improve the management of the adult critically ill patient. However, these strategies have not been widely applied in the Intensive Care Units (ICUs). The aim is to elaborate the recommendations for the standardization of the treatment of critical patients. A panel of experts from the thirteen working groups (WG) of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) was selected and nominated by virtue of clinical expertise and/or scientific experience to carry out the recommendations. Available scientific literature in the management of adult critically ill patients from 2002 to 2016 was extracted. The clinical evidence was discussed and summarised by the experts in the course of a consensus finding of every WG and finally approved by the WGs after an extensive internal review process that was carried out between December 2015 and December 2016. A total of 65 recommendations were developed, of which 5 corresponded to each of the 13 WGs. These recommendations are based on the opinion of experts and scientific knowledge, and are intended as a guide for the intensivists in the management of critical patients.

Faecal egg counts and expulsion dynamics of the whipworm, Trichuris trichiura following self-infection.

More than 400 million humans are estimated to be infected with the intestinal helminth parasite, Trichuris trichiura. The infection is chronic in nature and high-intensity infection can lead to colitis, anaemia, Trichuris Dysentery Syndrome and reduced cognitive performance. Single doses of 400 mg albendazole or 500 mg mebendazole (MBZ) are used in mass drug administration programmes, but this has been shown to be insufficient. In this study, worm expulsion dynamics are described after MBZ treatment, given as a multi-dose and single-dose treatment in two separate T. trichiura self-infection studies. Worm expulsion dynamics post-treatment showed a similar pattern regardless of the dose regime, with the first worms observed on day 2 and the last worms expelled on days 9 and 13 post-treatment. Establishment of a chronic infection was observed following the inefficient single-dose treatment. The prepatent period was 13-16 weeks in both studies and worms were found to have a lifespan of at least 1 year and 10 months. These self-infection studies provide key information on the chronicity of T. trichiura infections, expulsion dynamics after anthelmintic treatment and the prepatent period, as well as the fecundity of female worms, which was around 18,000 eggs/female per day.

Limitation of life-sustaining treatment in patients with prolonged admission to the ICU. Current situation in Spain as seen from the EPIPUSE Study.

OBJECTIVE: Limitation of life-sustaining treatment (LLST) is a recommended practice in certain circumstances. Limitation practices are varied, and their application differs from one center to another. The present study evaluates the current situation of LLST practices in patients with prolonged admission to the ICU who suffer worsening of their condition. DESIGN: A prospective, observational cohort study was carried out. SETTING: Seventy-five Spanish ICUs. PATIENTS: A total of 589 patients suffering 777 complications or adverse events with organ function impairment after day 7 of admission, during a three-month recruitment period. MAIN VARIABLES OF INTEREST: The timing of limitation, the subject proposing LLST, the degree of agreement within the team, the influence of LLST upon the doctor-patient-family relationship, and the way in which LLST is implemented. RESULTS: LLST was proposed in 34.3% of the patients presenting prolonged admission to the ICU with severe complications. The incidence was higher in patients with moderate to severe lung disease, cancer, immunosuppressive treatment or dependence for basic activities of daily living. LLST was finally implemented in 97% of the cases in which it was proposed. The decision within the medical team was unanimous in 87.9% of the cases. The doctor-patient-family relationship usually does not change or even improves in this situation. CONCLUSION: LLST in ICUs is usually carried out under unanimous decision of the medical team, is performed more frequently in patients with severe comorbidity, and usually does not have a negative impact upon the relationship with the patients and their families.

[A review of bioethics in the Intensive Care Unit: The autonomy and role of relatives and legal representatives]. / Revisión sobre bioética en la Unidad de Cuidados Intensivos: sobre la autonomía y el papel de los familiares y los representantes legales.

In recent decades we have witnessed a change in mentality in which patient autonomy has reached significant preponderance, with informed consent as the prime example. The approach in situations where the patient cannot make decisions varies from one country to another, affording greater or lesser importance to the wishes of the family when a surrogate has not been designated. Several studies show discrepancies between the decisions of patients and that the decisions which their surrogates have taken for them. We review concepts such as greatest benefit, evaluate the potential limitations of advance care directives, and consider different options when the action or treatment proposed by professionals comes into conflict with the ideas expressed by the patient's family or surrogates, and which has led to different legally sanctioned solutions in some regions.

Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) and the Spanish Society of Pediatric Intensive Care (SECIP) consensus recommendations for ECMO transport.

The evolution of extracorporeal membrane oxygenation treatment and the transport of patients receiving this treatment has changed dramatically in the last decade unevenly in different regions. The creation of specialized referral centers has been shown to improve outcomes. For all these reasons, it has been necessary to create networks of specialized teams and the number of secondary transports of patients with this treatment is increasing. In order to improve the quality of treatment and offer a guide to the services involved in these transports, the critical transport working groups of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) and the Spanish Society of Pediatric Intensive Care (SECIP) have carried out a joint effort to prepare these recommendations, focused on the following aspects: indications, reference center systems, means of transport, characteristics and equipment, human teams, training and clinical safety.

Risk factors for lymphedema after breast surgery: A prospective cohort study in the era of sentinel lymph node biopsy.

INTRODUCTION: The Objective was to investigate the incidence of lymphedema after breast cancer treatment and to analyze the risk factors involved in a tertiary level hospital. METHODS: Prospective longitudinal observational study over 3 years post-breast surgery. 232 patients undergoing surgery for breast cancer at our institution between September 2013 and February 2018. Sentinel lymph node biopsy (SLNB) or axillary lymphadenectomy (ALND) were mandatory in this cohort. In total, 201 patients met the inclusion criteria and had a median follow-up of 31 months (range, 1-54 months). Lymphedema was diagnosed by circumferential measurements and truncated cone calculations. Patients and tumor characteristics, shoulder range of motion limitation and local and systemic therapies were analyzed as possible risk factors for lymphedema. RESULTS: Most cases of lymphedema appeared in the first 2 years. 13.9% of patients developed lymphedema: 31% after ALND and 4.6% after SLNB (p < 0.01), and 46.7% after mastectomy and 11.3% after breast-conserving surgery (p < 0.01). The lymphedema rate increased when axillary radiotherapy (RT) was added to radical surgery: 4.3% for SLNB alone, 6.7% for SLNB + RT, 17.6% for ALND alone, and 35.2% for ALND + RT (p < 0.01). In the multivariate analysis, the only risk factors associated with the development of lymphedema were ALND and mastectomy, which had hazard ratios (95% confidence intervals) of 7.28 (2.92-18.16) and 3.9 (1.60-9.49) respectively. CONCLUSIONS: The main risk factors for lymphedema were the more radical surgeries (ALND and mastectomy). The risk associated with these procedures appeared to be worsened by the addition of axillary radiotherapy. A follow-up protocol in patients with ALND lasting at least two years, in which special attention is paid to these risk factors, is necessary to guarantee a comprehensive control of lymphedema that provides early detection and treatment.

Trophic ecology of Atlantic bluefin tuna Thunnus thynnus larvae.

Feeding intensity, diet composition, selectivity, energy ingestion and dietary niche breadth of larval Atlantic bluefin tuna Thunnus thynnus were studied on the eastern (Mediterranean) spawning grounds of the species. Larval T. thynnus were collected in the Balearic Archipelago (north-west Mediterranean Sea) during 2004 and 2005 using surveys specific for larval scombrids. Larvae between 2·6 and 8·7 mm standard length (L(S) ) are diurnal feeders, and 94% of the guts collected during daylight hours were full. The mean ±s.d. number of prey per gut was 7·1 ± 5·7, with mean ±s.d. ranging from 3·0 ± 1·6 in the smallest T. thynnus larvae to 11·1 ± 5·8 in 5·0-6·0 mm L(S) larvae. Up to 21 prey were found in a single larval gut (5·0-6·0 mm L(S) ) at the end of the day. Larvae progressively selected larger prey and exhibited increased carbon content concurrent with preflexion development of feeding and locomotory structures. Larvae of 5·0-6·0 mm L(S) exhibited positive selection of cladocerans over other prey (Chesson's index), whereas copepod nauplii dominated the diets of earlier stages. The dietary niche breadth measured increased initially but decreased at c. 5·5 mm L(S) . Appendicularians were found in the diet of larger larval sizes, but no piscivory was observed. Results are discussed in light of the sparse existing data for larval T. thynnus and other larval tuna species.

[Outpatient or short-stay videothoracoscopy-assisted thoracic sympathectomy: anesthesia in 445 cases]. / Anestesia para simpatectomía torácica por videotoracoscopia en régimen ambulatorio o corta estancia: experiencia en 445 casos.

OBJECTIVE: To demonstrate the safety of outpatient or short-stay bilateral videothoracoscopy-assisted thoracic sympathectomy. PATIENTS AND METHODS: The medical records of 445 who underwent bilateral videothoracoscopy-assisted thoracic sympathectomy were reviewed; the same protocols were used to guide these outpatient or short-stay procedures in all cases. Intravenous anesthesia was provided. An orotracheal tube allowed for carrying out the sympathectomy procedure during short periods of apnea. A 2% lidocaine solution was infused through the thoracic drains, which were removed soon after surgery. Data on intraoperative respiratory variables, pain, and intra- and postoperative complications were gathered. The data for patients undergoing the procedure on an outpatient or short-stay basis were compared. RESULTS: No significant differences in demographic or perioperative variables were found between the 2 groups. In 3.6% of the patients in the series, there was a record of a postoperative pulmonary complication: 4 therapeutic minithoracotomies; 1 subcutaneous emphysema without radiologic changes; 9 residual pneumothoraces, 2 requiring pleural drainage; 1 chylothorax; and 1 delayed hemothorax. With the exception of the late-developing hemothorax, all complications were diagnosed and treated in the immediate postoperative period. In the outpatient surgery group, unplanned admissions because of patient refusal to leave occurred in 6.5% of the cases. CONCLUSION: The low incidence of complications, and especially the finding that complications are detected in the early recovery period, indicate that this procedure can be performed on an outpatient basis.

[The heart and kidney in diabetes: Heart and kidney in diabetes]. / Corazón y riñón en la diabetes: efectos de los glucosúricos.

The diabetic kidney presents excess expression and activity of the SGLT2 transporter of the proximal tubule. This situation increases the renal reabsorption of Na and glucose and reduces their distal supply. In addition to the metabolic effects on the internal environment of this excess reabsorbed glucose, the renal tubule is subjected to glycosylated stress capable of locally activating both apoptosis and inflammasome. The result is a progressive loss of nephron units, activation of transition of mesangial epithelium and collagen deposition. Activation of insulin signalling by the MAP kinase pathway and resistance to the metabolic effects of insulin take place. This is simultaneously combined with afferent vasodilation due to hyperglycaemia, tubuloglomerular feedback inhibition due to reduced distal fluid supply, podocyte dedifferentiation and reduction in their number, the latter effects being due to insulin resistance. The result is self-feeding renal damage, with intraglomerular hyper-pressure, podocyte dedifferentiation, tubular apoptosis, and local and distant activation of inflammasome. All these effects are susceptible to be totally or partially corrected by inhibiting glucose transport via the SGLT transporters.

Recommendations for the evaluation and management of the anticipated and non-anticipated difficult airway of the Societat Catalana d'Anestesiologia, Reanimació i Terapèutica del Dolor, based on the adaptation of clinical practice guidelines and expert consensus. / Recomendaciones para la evaluación y manejo de la vía aérea difícil prevista y no prevista de la Societat Catalana d'Anestesiologia, Reanimació i Terapèutica del Dolor, basadas en la adaptación de guías de práctica clínica y consenso de expertos.

The Airway Division of the Catalan Society of Anaesthesiology, Intensive Care and Pain Management (SCARTD) presents its latest guidelines for the evaluation and management of the difficult airway. This update includes the technical advances and changes observed in clinical practice since publication of the first edition of the guidelines in 2008. The recommendations were defined by a consensus of experts from the 19 participating hospitals, and were adapted from 5 recently published international guidelines following an in-depth analysis and systematic comparison of their recommendations. The final document was sent to the members of SCARTD for evaluation, and was reviewed by 11 independent experts. The recommendations, therefore, are supported by the latest scientific evidence and endorsed by professionals in the field. This edition develops the definition of the difficult airway, including all airway management techniques, and places emphasis on evaluating and classifying the airway into 3 categories according to the anticipated degree of difficulty and additional safety considerations in order to plan the management strategy. Pre-management planning, in terms of preparing patients and resources and optimising communication and interaction between all professionals involved, plays a pivotal role in all the scenarios addressed. The guidelines reflect the increased presence of video laryngoscopes and second-generation devices in our setting, and promotes their routine use in intubation and their prompt use in cases of unanticipated difficult airway. They also address the increased use of ultrasound imaging as an aid to evaluation and decision-making. New scenarios have also been included, such as the risk of bronchoaspiration and difficult extubation Finally, the document outlines the training and continuing professional development programmes required to guarantee effective and safe implementation of the guidelines.

Update and recommendations in decision making referred to limitation of advanced life support treatment. / Puesta al día y recomendaciones en la toma de decisiones de limitación de tratamientos de soporte vital.

The Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) Bioethics Working Group has developed recommendations on the Limitation of Advanced Life Support Treatment (LLST) decisions, with the aim of reducing variability in clinical practice and of improving end of life care in critically ill patients. The conceptual framework of LLST and futility are explained. Recommendations referred to new forms of LLST encompassing also the adequacy of other treatments and diagnostic methods are developed. In addition, planning of the possible clinical courses following the decision of LLST is commented. The importance of advanced care planning in decision-making is emphasized, and intensive care oriented towards organ donation at end of life in the critically ill patient is described. The integration of palliative care in the critical patient treatment is promoted in end of life stages in the Intensive Care Unit.

Consensus Document of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC), the Spanish Society of Otorhinolaryngology and Head and Neck Surgery (SEORL-CCC) and the Spanish Society of Anesthesiology and Resuscitation (SEDAR) on Tracheotomy in Patients with COVID-19 Infection. / Documento de consenso de la Sociedad Española de Medicina Intensiva, Crítica, y Unidades Coronarias (SEMICYUC), la Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello (SEORL-CCC) y la Sociedad Española de Anestesiología y Reanimación (SEDAR) sobre la traqueotomía en pacientes con COVID-19.

The current COVID-19 pandemic has rendered up to 15% of patients under mechanical ventilation. Because the subsequent tracheotomy is a frequent procedure, the three societies mostly involved (SEMICYUC, SEDAR and SEORL-CCC) have setup a consensus paper that offers an overview about indications and contraindications of tracheotomy, be it by puncture or open, clarifying its respective advantages and enumerating the ideal conditions under which they should be performed, as well as the necessary steps. Regular and emergency situations are displayed together with the postoperative measures.

[Recommendations on cardiopulmonary resuscitation in patients with suspected or confirmed SARS-CoV-2 infection (COVID-19). Executive summary]. / Recomendaciones sobre reanimación cardiopulmonar en pacientes con sospecha o infección confirmada por SARS-CoV-2 (COVID-19). Resumen ejecutivo.

The SARS-CoV-2 pandemic has created new scenarios that require modifications to the usual cardiopulmonary resuscitation protocols. The current clinical guidelines on the management of cardiorespiratory arrest do not include recommendations for situations that apply to this context. Therefore, the National Cardiopulmonary Resuscitation Plan of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC), in collaboration with the Spanish Group of Pediatric and Neonatal CPR and with the Teaching Life Support in Primary Care program of the Spanish Society of Family and Community Medicine (SEMFyC), have written these recommendations, which are divided into 5 parts that address the main aspects for each healthcare setting. This article consists of an executive summary of them.

[Recommendations of the Working Groups from the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) for the management of adult critically ill patients in the coronavirus disease (COVID-19)]. / Recomendaciones de «hacer¼ y «no hacer¼ en el tratamiento de los pacientes críticos ante la pandemia por coronavirus causante de COVID-19 de los Grupos de Trabajo de la Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias (SEMICYUC).

On March 11, 2020, the Director-General of the World Health Organization (WHO) declared the disease caused by SARS-CoV-2 (COVID-19) as a pandemic. The spread and evolution of the pandemic is overwhelming the healthcare systems of dozens of countries and has led to a myriad of opinion papers, contingency plans, case series and emerging trials. Covering all this literature is complex. Briefly and synthetically, in line with the previous recommendations of the Working Groups, the Spanish Society of Intensive, Critical Medicine and Coronary Units (SEMICYUC) has prepared this series of basic recommendations for patient care in the context of the pandemic.
