Vascular catheter-related infections: an endemic disease in healthcare institutions. An opinion paper of the Spanish Society of Cardiovascular Infections (SEICAV).

Catheter-related infections (CRI) are a serious healthcare problem due to their potential to cause serious complications, including bacteraemia or infective endocarditis, and to increase patient morbidity and mortality. In addition, these in fections significantly prolong hospital stay and cost. Preventing CRI is crucial and is considered a criterion for quality and safety in healthcare. For these reasons, the Spanish Society of Cardiovascular Infections (SEICAV) has considered it pertinent to review this topic, with experts in different areas including clinical microbiologists, infectious disease specialists, surgeons and nurses. The data were presented at a session held at the Ramón Areces Foundation, which was organised in the form of specific questions grouped into three round tables. The first panel analysed the scale of the problem including epidemiological, clinical and diagnostic aspects; the second panel addressed advances in the treatment of CRI; and the third panel reviewed developments in the prevention of CRI. The recorded session is available on the Areces Foundation website and we believe it maybe of interest not only to health professionals, but also to any non-expert citizen interested in the subject.

Predictors of poor health-related quality of life among people living with HIV aged ≥60 years in the PISCIS cohort: Findings from the Vive+ project.

INTRODUCTION: Advancements in and accessibility to effective antiretroviral therapy has improved the life expectancy of people living with HIV, increasing the proportion of people living with HIV reaching older age (≥60 years), making this population's health-related quality of life (HRQoL) more relevant. Our aim was to identify the determinants of poor HRQoL in people living with HIV aged ≥60 years and compare them with those of their younger counterparts. METHODS: We used data from the 'Vive+' study, a cross-sectional survey conducted between October 2019 and March 2020, nested within the PISCIS cohort of people living with HIV in Catalonia and the Balearic Islands, Spain. We used the 12-item short-form survey (SF-12), divided into a physical component summary (PCS) and a mental component summary (MCS), to evaluate HRQoL. We used the least absolute shrinkage and selection operator for variable selection and used multivariable regression models to identify predictors. RESULTS: Of the 1060 people living with HIV (78.6% males) who participated in the study, 209 (19.7%) were aged ≥60 years. When comparing older people living with HIV (≥60 years) and their younger counterparts, older people exhibited a worse PCS (median 51.3 [interquartile range {IQR} 46.0-58.1] vs. 46.43 [IQR 42.5-52.7], p < 0.001) but a similar MCS (median 56.0 [IQR 49.34-64.7] vs. 57.0 [IQR 48.9-66.3], p = 0.476). In the multivariable analysis, cognitive function correlated with a PCS (ß correlation factor [ß] -0.18, p = 0.014), and depressive symptoms and satisfaction with social role correlated with an MCS (ß 0.61 and ß -0.97, respectively, p < 0.001) in people living with HIV aged ≥60 years. CONCLUSION: Depressive symptoms, poor cognitive function, and lower satisfaction with social roles predict poorer HRQoL in older people living with HIV. These factors need to be considered when designing targeted interventions.

The incidence of potentially serious complications during non-obstetric anaesthetic practice in the United Kingdom: an analysis from the 7th National Audit Project (NAP7) activity survey.

Complications and critical incidents arising during anaesthesia due to patient, surgical or anaesthetic factors, may cause harm themselves or progress to more severe events, including cardiac arrest or death. As part of the 7th National Audit Project of the Royal College of Anaesthetists, we studied a prospective national cohort of unselected patients. Anaesthetists recorded anonymous details of all cases undertaken over 4 days at their site through an online survey. Of 416 hospital sites invited to participate, 352 (85%) completed the survey. Among 24,172 cases, 1922 discrete potentially serious complications were reported during 1337 (6%) cases. Obstetric cases had a high reported major haemorrhage rate and were excluded from further analysis. Of 20,996 non-obstetric cases, 1705 complications were reported during 1150 (5%) cases. Circulatory events accounted for most complications (616, 36%), followed by airway (418, 25%), metabolic (264, 15%), breathing (259, 15%), and neurological (41, 2%) events. A single complication was reported in 851 (4%) cases, two complications in 166 (1%) cases and three or more complications in 133 (1%) cases. In non-obstetric elective surgery, all complications were 'uncommon' (10-100 per 10,000 cases). Emergency (urgent and immediate priority) surgery accounted for 3454 (16%) of non-obstetric cases but 714 (42%) of complications with severe hypotension, major haemorrhage, severe arrhythmias, septic shock, significant acidosis and electrolyte disturbances all being 'common' (100-1000 per 10,000 cases). Based on univariate analysis, complications were associated with: younger age; higher ASA physical status; male sex; increased frailty; urgency and extent of surgery; day of the week; and time of day. These data represent the rates of potentially serious complications during routine anaesthesia care and may be valuable for risk assessment and patient consent.

Peri-operative cardiac arrest: management and outcomes of patients analysed in the 7th National Audit Project of the Royal College of Anaesthetists.

The 7th National Audit Project of the Royal College of Anaesthetists studied peri-operative cardiac arrest in the UK, a topic of importance to patients, anaesthetists and surgeons. We report the results of the 12-month registry phase, from 16 June 2021 to 15 June 2022, focusing on management and outcomes. Among 881 cases of peri-operative cardiac arrest, the initial rhythm was non-shockable in 723 (82%) cases, most commonly pulseless electrical activity. There were 665 (75%) patients who survived the initial event and 384 (52%) who survived to hospital discharge. A favourable functional outcome (based on modified Rankin Scale score) was reported for 249 (88%) survivors. Outcomes varied according to arrest rhythm. The highest rates of survival were seen for bradycardic cardiac arrests with 111 (86%) patients surviving the initial event and 77 (60%) patients surviving the hospital episode. The lowest survival rates were seen for patients with pulseless electrical activity, with 312 (68%) surviving the initial episode and 156 (34%) surviving to hospital discharge. Survival to hospital discharge was worse in patients at the extremes of age with 76 (40%) patients aged > 75 y and 9 (45%) neonates surviving. Hospital survival was also associated with surgical priority, with 175 (88%) elective patients and 176 (37%) non-elective patients surviving to discharge. Outcomes varied with the cause of cardiac arrest, with lower initial survival rates for pulmonary embolism (5, 31%) and bone cement implantation syndrome (9, 45%), and hospital survival of < 25% for pulmonary embolism (0), septic shock (13, 24%) and significant hyperkalaemia (1, 20%). Overall care was rated good in 464 (53%) cases, and 18 (2%) cases had overall care rated as poor. Poor care elements were present in a further 245 (28%) cases. Care before cardiac arrest was the phase most frequently rated as poor (92, 11%) with elements of poor care identified in another 186 (21%) cases. These results describe the management and outcomes of peri-operative cardiac arrest in UK practice for the first time.

Peri-operative cardiac arrest: epidemiology and clinical features of patients analysed in the 7th National Audit Project of the Royal College of Anaesthetists.

The 7th National Audit Project of the Royal College of Anaesthetists studied peri-operative cardiac arrest in the UK, a topic of importance to patients, anaesthetists and surgeons. Here we report the results of the 12-month registry, from 16 June 2021 to 15 June 2022, focusing on epidemiology and clinical features. We reviewed 881 cases of peri-operative cardiac arrest, giving an incidence of 3 in 10,000 anaesthetics (95%CI 3.0-3.5 per 10,000). Incidence varied with patient and surgical factors. Compared with denominator survey activity, patients with cardiac arrest: included more males (56% vs. 42%); were older (median (IQR) age 60.5 (40.5-80.5) vs. 50.5 (30.5-70.5) y), although the age distribution was bimodal, with infants and patients aged > 66 y overrepresented; and were notably more comorbid (73% ASA physical status 3-5 vs. 27% ASA physical status 1-2). The surgical case-mix included more weekend (14% vs. 11%), out-of-hours (19% vs. 10%), non-elective (65% vs. 30%) and major/complex cases (60% vs. 28%). Cardiac arrest was most prevalent in orthopaedic trauma (12%), lower gastrointestinal surgery (10%), cardiac surgery (9%), vascular surgery (8%) and interventional cardiology (6%). Specialities with the highest proportion of cases relative to denominator activity were: cardiac surgery (9% vs. 1%); cardiology (8% vs. 1%); and vascular surgery (8% vs. 2%). The most common causes of cardiac arrest were: major haemorrhage (17%); bradyarrhythmia (9%); and cardiac ischaemia (7%). Patient factors were judged a key cause of cardiac arrest in 82% of cases, anaesthesia in 40% and surgery in 35%.

The 7th National Audit Project (NAP7) baseline survey of individual anaesthetists: preparedness for and experiences of peri-operative cardiac arrest.

The Royal College of Anaesthetists' 7th National Audit Project baseline survey assessed knowledge, attitudes, practices and experiences of peri-operative cardiac arrests among UK anaesthetists and Anaesthesia Associates. We received 10,746 responses, representing a 71% response rate. In-date training in adult and paediatric advanced life support was reported by 9646 (90%) and 7125 (66%) anaesthetists, respectively. There were 8994 (84%) respondents who were confident in leading a peri-operative cardiac arrest, with males more confident than females, but only 5985 (56%) were confident in leading a debrief and 7340 (68%) communicating with next of kin. In the previous two years, 4806 (46%) respondents had managed at least one peri-operative cardiac arrest, of which 321 (7%) and 189 (4%) of these events involved a child or an obstetric patient, respectively. Respondents estimated the most common causes of peri-operative cardiac arrest to be hypovolaemia, hypoxaemia and cardiac ischaemia, with haemorrhage coming fifth. However, the most common reported causes for the most recently attended peri-operative cardiac arrest were haemorrhage; (927, 20%); anaphylaxis (474, 10%); and cardiac ischaemia (397, 9%). Operating lists or shifts were paused or stopped after 1330 (39%) cardiac arrests and 1693 (38%) respondents attended a debrief, with 'hot' debriefs most common. Informal wellbeing support was relatively common (2458, 56%) and formal support was uncommon (472, 11%). An impact on future care delivery was reported by 196 (4%) anaesthetists, most commonly a negative psychological impact. Management of a peri-operative cardiac arrest during their career was reported by 8654 (85%) respondents. The overall impact on professional life was more often judged positive (2630, 30%) than negative (1961, 23%), but impact on personal life was more often negative.

Organisation of UK hospitals and anaesthetic departments in the treatment of peri-operative cardiac arrest: an analysis from the 7th National Audit Project (NAP7) local co-ordinator baseline survey.

We report the results of the Royal College of Anaesthetists' 7th National Audit Project organisational baseline survey sent to every NHS anaesthetic department in the UK to assess preparedness for treating peri-operative cardiac arrest. We received 199 responses from 277 UK anaesthetic departments, representing a 72% response rate. Adult and paediatric anaesthetic care was provided by 188 (95%) and 165 (84%) hospitals, respectively. There was no paediatric intensive care unit on-site in 144 (87%) hospitals caring for children, meaning transfer of critically ill children is required. Remote site anaesthesia is provided in 182 (92%) departments. There was a departmental resuscitation lead in 113 (58%) departments, wellbeing lead in 106 (54%) and departmental staff wellbeing policy in 81 (42%). A defibrillator was present in every operating theatre suite and in all paediatric anaesthesia locations in 193 (99%) and 149 (97%) departments, respectively. Advanced airway equipment was not available in: every theatre suite in 13 (7%) departments; all remote locations in 103 (57%) departments; and all paediatric anaesthesia locations in 23 (15%) departments. Anaesthetic rooms were the default location for induction of anaesthesia in adults and children in 148 (79%) and 121 (79%) departments, respectively. Annual updates in chest compressions and in defibrillation were available in 149 (76%) and 130 (67%) departments, respectively. Following a peri-operative cardiac arrest, debriefing and peer support programmes were available in 154 (79%) and 57 (29%) departments, respectively. While it is likely many UK hospitals are very well prepared to treat anaesthetic emergencies including cardiac arrest, the survey suggests this is not universal.

Radioquimioterapia neoadyuvante en cáncer de recto: Relevancia clínica del downstaging y la respuesta patológica completa

Antecedentes: La radioquimioterapia neoadyuvante es uno de los pilares del tratamiento del cáncer de recto localmente avanzado. La neoadyuvancia ha demostrado disminuir la recidiva local, generando también un downstaging tumoral, llegando incluso a una respuesta patológica completa (RPC), esta última relacionada con una mejor sobrevida global (SG) y sobrevida libre de enfermedad (SLE). Objetivo: Reportar los resultados anátomo-patológicos del tratamiento con radioquimioterapia en cáncer de recto, analizando su relación con la SG y la SLE. Material y Método: Estudio de cohorte prospectivo. Se analiza base de datos de cirugías coloproctológicas del Hospital Clínico de la Universidad de Chile, entre los años 20042019, incluyendo pacientes con cáncer de recto medio y bajo localmente avanzados, los cuales recibieron neoadyuvancia y posteriormente cirugía. Se realizó el análisis de sobrevida con el método de Kaplan-Meier y el test Log-rank para su comparación. Se consideró estadísticamente significativo un valor de p < 0,05. Resultados: 411 pacientes fueron operados por cáncer de recto, 143 pacientes recibieron neoadyuvancia, el 19% registró RPC. La SG del grupo con RPC fue 94% (IC 95%; 59,79-79,41%) mientras que la del grupo sin RPC fue 71% (IC 95%; 66,64-99,20%) (p = 0,018), la SLE en aquellos pacientes con RPC alcanzó un 100%, mientras que en aquellos sin RPC fue 74% (IC 95%; 64,08-81,28) (p = 0,008). Conclusiones: Los pacientes con RPC mostraron mejores resultados a largo plazo que aquellos sin RPC. La RPC podría indicar un perfil tumoral biológico favorable, con menos tendencia a la recurrencia y mejor supervivencia.

Background: One of the mainstays in the treatment of locally advanced rectal cancer is neoadjuvant chemoradiotherapy. Neoadjuvant therapy have demonstrated to decrease local recurrence, also generating tumor downstaging, even leading to a pathological complete response (PCR), the latter related to better overall survival (OS) and disease-free survival (SLE). Aim: To report the anatomo-pathological results of treatment with chemoradiotherapy in rectal cancer, analyzing the relationship with OS and SLE. Material and Method: Prospective cohort study. A database of colorectal surgeries from the Clinical Hospital of the University of Chile between the years 2004-2019, including patients with locally advanced low and middle rectal cancer, who received neoadjuvant and later surgery. Survival analysis was made with the Kaplan-Meier method and the Log-rank test for comparison. A value of p < 0.05 was considered statistically significant. Results: 411 patients underwent surgery for rectal cancer, 143 patients received neoadjuvant therapy, 19% registered PCR. The OS of the group with PCR was 94% (95% CI; 59.79-79.41%) while that of the group without PCR was 71% (95% CI; 66.64-99.20%) (p = 0.018), the SLE in those patients with PCR reached 100%, while in those without PCR it was 74% (95% CI; 64.08-81.28) (p = 0.008). Conclusions: Patients with PCR have better long-term results than those without PCR. PCR could indicate a favorable biological tumor profile, with less tendency to recurrence and improved survival.

Sexual differentiation of estrogen receptor alpha subpopulations in the ventromedial nucleus of the hypothalamus.

Estrogen receptor (ER) α-expressing neurons in the ventrolateral area of the ventromedial hypothalamus (VMHvl) are implicated in the control of many behaviors and physiological processes, some of which are sex-specific. Recently, three sex-differentiated ERα subpopulations have been discovered in the VMHvl marked by co-expression with tachikinin1 (Tac1), reprimo (Rprm), or prodynorphin (Pdyn), that may subserve specific functions. These markers show sex differences in adulthood: females have many more Tac1/Esr1 and Rprm/Esr1 co-expressing cells, while males have more Pdyn/Esr1 cells. In this study, we sought to understand the development of these sex differences and pinpoint the sex-differentiating signal. We examined developmental changes in the number of Esr1 cells co-expressing Tac1, Rprm or Pdyn using single-molecule in situ hybridization. We found that both sexes have similarly high numbers of Tac1/Esr1 and Rprm/Esr1 cells at birth, but newborn males have many more Pdyn/Esr1 cells than females. However, the number of cells with Tac1/Esr1 and Rprm/Esr1 co-expression markedly decreases by weaning in males, but not females, leading to sex differences in neurochemical expression. Female mice administered testosterone at birth have expression patterns akin to male mice. Thus, a substantial neurochemical reorganization of the VMHvl occurs in males between birth and weaning that likely underlies the previously reported sex differences in behavioral and physiological responses to estrogens in adulthood.

DNA methylation and demethylation shape sexual differentiation of neurochemical phenotype.

Some of the best-studied neural sex differences depend on differential cell death in males and females, but other sex differences persist even if cell death is prevented. These include sex differences in neurochemical phenotype (i.e., stable patterns of gene expression). Work in our laboratory over the last several years has tested the hypothesis that sex differences in DNA methylation early in life underlie sexual differentiation of neuronal phenotype. We have shown that 1) expression of enzymes that place or remove DNA methylation marks is greatest during the first week of life in the mouse brain and overlaps with the perinatal critical period of sexual differentiation; 2) a transient inhibition of DNA methylation during neonatal life abolishes several sex differences in cell phenotype in the mouse hypothalamus; 3) both DNA methylation and de-methylation contribute to the development of neural sex differences; and 4) the effects of DNA methylation and de-methylation are brain region- and cell type-specific.

Patient characteristics, anaesthetic workload and techniques in the UK: an analysis from the 7th National Audit Project (NAP7) activity survey.

Detailed contemporary knowledge of the characteristics of the surgical population, national anaesthetic workload, anaesthetic techniques and behaviours are essential to monitor productivity, inform policy and direct research themes. Every 3-4 years, the Royal College of Anaesthetists, as part of its National Audit Projects (NAP), performs a snapshot activity survey in all UK hospitals delivering anaesthesia, collecting patient-level encounter data from all cases under the care of an anaesthetist. During November 2021, as part of NAP7, anaesthetists recorded details of all cases undertaken over 4 days at their site through an online survey capturing anonymous patient characteristics and anaesthetic details. Of 416 hospital sites invited to participate, 352 (85%) completed the activity survey. From these, 24,177 reports were returned, of which 24,172 (99%) were included in the final dataset. The work patterns by day of the week, time of day and surgical specialty were similar to previous NAP activity surveys. However, in non-obstetric patients, between NAP5 (2013) and NAP7 (2021) activity surveys, the estimated median age of patients increased by 2.3 years from median (IQR) of 50.5 (28.4-69.1) to 52.8 (32.1-69.2) years. The median (IQR) BMI increased from 24.9 (21.5-29.5) to 26.7 (22.3-31.7) kg.m-2 . The proportion of patients who scored as ASA physical status 1 decreased from 37% in NAP5 to 24% in NAP7. The use of total intravenous anaesthesia increased from 8% of general anaesthesia cases to 26% between NAP5 and NAP7. Some changes may reflect the impact of the COVID-19 pandemic on the anaesthetic population, though patients with confirmed COVID-19 accounted for only 149 (1%) cases. These data show a rising burden of age, obesity and comorbidity in patients requiring anaesthesia care, likely to impact UK peri-operative services significantly.

Methods of the 7th National Audit Project (NAP7) of the Royal College of Anaesthetists: peri-operative cardiac arrest.

Cardiac arrest in the peri-operative period is rare but associated with significant morbidity and mortality. Current reporting systems do not capture many such events, so there is an incomplete understanding of incidence and outcomes. As peri-operative cardiac arrest is rare, many hospitals may only see a small number of cases over long periods, and anaesthetists may not be involved in such cases for years. Therefore, a large-scale prospective cohort is needed to gain a deep understanding of events leading up to cardiac arrest, management of the arrest itself and patient outcomes. Consequently, the Royal College of Anaesthetists chose peri-operative cardiac arrest as the 7th National Audit Project topic. The study was open to all UK hospitals offering anaesthetic services and had a three-part design. First, baseline surveys of all anaesthetic departments and anaesthetists in the UK, examining respondents' prior peri-operative cardiac arrest experience, resuscitation training and local departmental preparedness. Second, an activity survey to record anonymised details of all anaesthetic activity in each site over 4 days, enabling national estimates of annual anaesthetic activity, complexity and complication rates. Third, a case registry of all instances of peri-operative cardiac arrest in the UK, reported confidentially and anonymously, over 1 year starting 16 June 2021, followed by expert review using a structured process to minimise bias. The definition of peri-operative cardiac arrest was the delivery of five or more chest compressions and/or defibrillation in a patient having a procedure under the care of an anaesthetist. The peri-operative period began with the World Health Organization 'sign-in' checklist or first hands-on contact with the patient and ended either 24 h after the patient handover (e.g. to the recovery room or intensive care unit) or at discharge if this occured earlier than 24 h. These components described the epidemiology of peri-operative cardiac arrest in the UK and provide a basis for developing guidelines and interventional studies.

Protective role of Portuguese natural mineral waters on skin aging: in vitro evaluation of anti-senescence and anti-oxidant properties.

Natural mineral waters (NMWs) emerge from the earth as springs and their beneficial therapeutic effect has been empirically recognized in different countries. Portugal has diverse NMW resources that are sought for the relief of different afflictions including dermatological complications. However, there is a lack of scientific validation supporting this empiric knowledge. In this study, we aimed to screen the in vitro bioactivity of Portuguese NMWs with different chemical profiles, namely sulfurous/bicarbonate/sodic (SBS), bicarbonate/magnesium, sulfated/calcic, sulfurous/chlorinated/sodic, sulfurous/bicarbonate/fluoridated/sodic, and chlorinated/sodic, focusing on aging-related skin alterations. Mouse skin fibroblasts and macrophages were exposed to culture medium prepared in different NMWs. Cellular viability was evaluated by MTT assay and etoposide-induced senescence was analyzed through the beta-galactosidase staining kit. Wound healing was investigated by the scratch assay, and phototoxicity/photoprotection after UVA irradiation was evaluated using a neutral red solution. ROS production was quantified using the 2'7'-dichlorofluorescin diacetate dye, and the activity of superoxide dismutase (SOD) was analyzed by a commercial kit after lipopolysaccharide exposure. NMWs within the SBS profile demonstrated anti-senescence activity in skin fibroblasts, along with a variable effect on cellular viability. Among the tested NMWs, two decreased cellular senescence and preserved cell viability and were therefore selected for subsequent studies, together with a SBS NMW with therapeutic indications for dermatologic diseases. Overall, the selected NMW promoted wound healing in skin fibroblasts and activated SOD in macrophages, thus suggesting an anti-oxidant effect. None of the NMWs prevented phototoxicity after UV irradiation. Our results shed a light on the anti-aging potential of Portuguese NMW, supporting their putative application in cosmetic or medical products.

Utilidad de una estrategia nutricional sobre la dislipidemia en pacientes pediátricos con enfermedad renal crónica terminal / Usefulness of a nutritional strategy on dyslipidemia in pediatric patients with terminal chronic kidney disease

Antecedentes y objetivo: en la enfermedad renal crónica (ERC) existen múltiples factores que incrementan la presencia de la dislipidemia. El objetivo fue identificar la utilidad de una intervención nutricional sobre la dislipidemia, en niños con ERC terminal, a los 6 meses del inicio de la intervención. Materiales y métodos: estudio cuasiexperimental (antes y después). Se incluyeron pacientes con ERC terminal en diálisis peritoneal y hemodiálisis. A cada niño se le realizaron una somatometría y un perfil de lípidos al inicio y a los 6 meses de seguimiento. Se realizó un manual de alimentación con semaforización de los alimentos, poniendo de color rojo los alimentos que se deben consumir en la menor cantidad posible, además de incluir alimentos a tamaño real utilizando modelos educativos. Para comparar las variables cuantitativas antes y después de la intervención se transformaron las variables a su logaritmo y se aplicó la “t” de Student pareada. Resultados: se analizaron 41 pacientes. Posteriormente a la intervención se modificaron los parámetros del perfil lipídico; las concentraciones de HDL se incrementaron (41,0 mg/dL vs. 44,4 mg/dL, p = 0,048), mientras que las concentraciones de triglicéridos disminuyeron (227,1 mg/dL vs. 185.9 mg/dL, p = 0,007), lo cual persiste incluso una vez excluidos aquellos pacientes que se encontraban bajo tratamiento hipolipemiante (195 mg/dL vs. 171,6, p = 0,049). En cuanto al estado de dislipidemia, la hipertrigliceridemia disminuyó sin alcanzar la significancia (80,5 % vs. 62,5 %, p = 0,073). Conclusiones: la intervención nutricional mejoró las concentraciones de HDL y triglicéridos pasados 6 meses de la intervención en niños con ERC terminal (AU)

Background and objective: in chronic kidney disease (CKD) there are several factors that increase the presence of dyslipidemia. The aim of this study was to identify the usefulness of a nutritional intervention, in children with terminal CKD, on dyslipidemia 6 months after intervention start. Materials and methods: a quasi-experiment study (before and after) was performed. End-stage CKD patients on peritoneal dialysis and hemodialysis were included. Each child underwent a determination somatometry, and lipid profile at the beginning and at 6 months of follow-up. A nutritional guide was made with food traffic lights, turning the food that should be consumed in the least amount possible in red. In addition to including life-size food using educational models. To compare the quantitative variables before and after the intervention, the variables were transformed to their logarithm and a paired Student's t-test was applied. Results: a total of 41 patients were analyzed. After the intervention, the parameters in the lipid profile were modified; meanwhile HDL concentrations increased (41.0 mg/dL vs 44.4 mg/dL, p = 0.048), triglyceride concentrations decreased (227.1 mg/dL vs 185.9 mg/dL, p = 0.007), and these changes persist even after excluding patients who were under lipid-lowering treatment (195 mg/dL vs 171.6, p = 0.049). Regarding the state of dyslipidemia, hypertriglyceridemia decreased, without reaching significance (80.5 % vs 62.5 %, p = 0.073). Conclusions: the nutritional intervention improved HDL and triglyceride concentrations 6 months afterwards in children with terminal CKD (AU)

Correction to: Early Stepdown From Echinocandin to Fluconazole Treatment in Candidemia: A Post Hoc Analysis of Three Cohort Studies.

[This corrects the article DOI: 10.1093/ofid/ofab250.].

Ceftobiprole: a clinical view.

Ceftobiprole is a broad-spectrum, fifth-generation cephalosporin currently approved for community-acquired and non-ventilator-associated hospital-acquired pneumonia. High bactericidal and anti-biofilm activity has been exhibited in in vitro and animal models. This, together with its synergism with other antibiotics against gram-positive bacteria, makes it an ideal candidate for treatment of complex infections, such as those associated with devices or infective endocarditis. More clinical data are needed to achieve drug positioning.

Early Stepdown From Echinocandin to Fluconazole Treatment in Candidemia: A Post Hoc Analysis of Three Cohort Studies.

BACKGROUND: There are no clear criteria for antifungal de-escalation after initial empirical treatments. We hypothesized that early de-escalation (ED) (within 5 days) to fluconazole is safe in fluconazole-susceptible candidemia with controlled source of infection. METHODS: This is a multicenter post hoc study that included consecutive patients from 3 prospective candidemia cohorts (2007-2016). The impact of ED and factors associated with mortality were assessed. RESULTS: Of 1023 candidemia episodes, 235 met inclusion criteria. Of these, 54 (23%) were classified as the ED group and 181 (77%) were classified as the non-ED group. ED was more common in catheter-related candidemia (51.9% vs 31.5%; P = .006) and episodes caused by Candida parapsilosis, yet it was less frequent in patients in the intensive care unit (24.1% vs 39.2%; P = .043), infections caused by Nakaseomyces glabrata (0% vs 9.9%; P = .016), and candidemia from an unknown source (24.1% vs 47%; P = .003). In the ED and non-ED groups, 30-day mortality was 11.1% and 29.8% (P = .006), respectively. Chronic obstructive pulmonary disease (odds ratio [OR], 3.97; 95% confidence interval [CI], 1.48-10.61), Pitt score > 2 (OR, 4.39; 95% CI, 1.94-9.20), unknown source of candidemia (OR, 2.59; 95% CI, 1.14-5.86), candidemia caused by Candida albicans (OR, 3.92; 95% CI, 1.48-10.61), and prior surgery (OR, 0.29; 95% CI, 0.08-0.97) were independent predictors of mortality. Similar results were found when a propensity score for receiving ED was incorporated into the model. ED had no significant impact on mortality (OR, 0.50; 95% CI, 0.16-1.53). CONCLUSIONS: Early de-escalation is a safe strategy in patients with candidemia caused by fluconazole-susceptible strains with controlled source of bloodstream infection and hemodynamic stability. These results are important to apply antifungal stewardship strategies.

Onychoscopy in a Colombian population with a diagnosis of toenail onychomycosis: an evaluation study for this diagnostic test.

BACKGROUND: Onychoscopy is a technique that uses a dermatoscope for the evaluation of specific features of different skin conditions that are not visible to the naked eye. There are few studies establishing parameters for the diagnosis of onychomycosis based on onychoscopy. Determining the sensitivity and specificity of a potentially new diagnostic test for onychomycosis requires an evaluation study of this new diagnostic test, as there are limited studies reporting onychoscopy results. AIM: To determine the sensitivity, specificity, positive predictive value and negative predictive value of onychoscopy findings in a Colombian population with onychomycosis. METHODS: We assessed outpatients with a diagnosis of toenail onychomycosis confirmed by potassium hydroxide preparation or fungal culture. Onychoscopy was performed using a dermatoscope, and digital images collected using a smartphone. RESULTS: The onychoscopy findings were: longitudinal striae, distal spiked pattern, distal irregular termination, linear edge and ruins aspect, while some patients were confirmed as having traumatic onycholysis. A statistically significant association was found between the clinical symptoms of onychomycosis and both the clinical feature of dyschromia and the onychoscopy feature of longitudinal striae. CONCLUSION: We suggest that this technique is an alternative method that should be used in patients with onychopathies because it has the potential to differentiate onychomycosis from traumatic onycholysis and another nail involvement.
