Reliability of different body temperature measurement sites during normothermic cardiac surgery.

INTRODUCTION: Patients undergoing cardiac surgery can experience significant thermal changes during the perioperative period and, for that reason, it is essential to monitor temperatures with adequate accuracy and precision during cardiopulmonary bypass (CPB). The primary aim of the current study was to measure the discrepancies between temperatures at different body sites during normothermic or mild hypothermic CPB. METHODS: 48 patients undergoing cardiac surgery participated in our study. Simultaneous temperatures were measured at nasopharynx, pulmonary artery, arterial outlet, venous inlet, forehead using a heat flux sensor, and urinary bladder at 5-min intervals throughout surgery. The Bland-Altman plot for repeated measures was used to assess concordance between methods. RESULTS: The duration of surgery was 360 min (interquartile range (IQR) 300-412), while the median cross-clamp time was 135 min (IQR 101-169). During the CPB time, the average difference between arterial outlet and nasopharyngeal temperature was -0.16°C (95% limits of agreement of ±0.93). The bias between arterial outlet and the venous inflow was 0.16°C and the 95% limits of agreement were -0.63 to 0.95°C. The Bland-Altman analysis showed an average difference between oxigenator arterial outlet and bladder probe of -0.62 (95% limits of agreement of ±1.3). The average difference between arterial outlet and Tcore™ temperatures was 0.08°C (95% limits of agreement of ±1.46). 25 patients (52.08%) presented nasopharyngeal temperatures higher than 37°C in the post-CPB period, but none of them exceeded 38°C. CONCLUSIONS: Perfusionists should be cautious when using the nasopharyngeal site as the only surrogate of brain temperature, even in normothermic cardiac surgery because the precision of measurements is not entirely adequate.

Xiroi II, an Evolved ASV Platform for Marine Multirobot Operations.

In this paper, we present the design, development and a practical use of an Autonomous Surface Vehicle (ASV) as a modular and flexible platform for a large variety of marine tasks including the coordination strategies with other marine robots. This work tackles the integration of an open-source Robot-Operating-System (ROS)-based control architecture that provides the ASV with a wide variety of navigation behaviors. These new ASV capabilities can be used to acquire useful data from the environment to survey, map, and characterize marine habitats. In addition, the ASV is used as a radio frequency relay point between an Autonomous Underwater Vehicle (AUV) and the ground station as well as to enhance the Acoustic Communication Link (ACL) with the AUV. In order to improve the quality of the ACL, a new Marine Multirobot System (MMRS) coordination strategy has been developed that aims to keep both vehicles close to each other. The entire system has been successfully designed, implemented, and tested in real marine environment robotic tasks. The experimental tests show satisfactory results both in ROS-based navigation architecture and the MMRS coordination strategy resulting in a significant improvement of the quality of the ACL.

Treatment patterns and outcomes in real-world transplant-ineligible patients newly diagnosed with multiple myeloma.

Despite the significant proportion of older patients with newly diagnosed multiple myeloma (MM), most clinical trials driving therapeutic decisions in routine practice include younger and presumably healthier patients than those in the real world. Furthermore, longitudinal studies suggest that elderly, transplant-ineligible patients with MM are not benefitting enough from new anti-MM agents. We retrospectively analyzed the profile of and treatment patterns and outcomes in 675 transplant-ineligible patients with MM who started frontline therapy in routine practice. The mean (SD) age was 75.6 (6.7) years; 152 (47.4%) had Eastern Cooperative Oncology Group performance status (ECOG PS) 2-4, and 73 (25.1%) had high cytogenetic risk. The most frequent frontline therapy was non-VMP bortezomib-based regimens (n=207; 30.7%), which were more frequent among patients with ECOG PS 0/1 and higher risk (e.g., international staging system (ISS) stage III, severely impaired glomerular filtrate rate (GFR), high lactate dehydrogenase (LDH), and high-risk cytogenetics); 185 patients (27.4%) started an attenuated (lite) VMP regimen, and 159 (23.6%) a VMP (VISTA) regimen. Median progression-free survival and overall survival (OS) were 15.3 months (95%CI 14.0-16.9) and 33.5 months (95%CI 29.1-37.2), respectively; 405 patients (78.2%) achieved partial response or better. Age, ECOG PS, ISS stage, serum LDH, GFR, cytogenetic risk, and treatment regimen significantly influenced OS. In this study, a remarkable proportion of transplant-ineligible patients with MM were older, frontline regimens were highly heterogeneous, and patients at higher risk often received less efficacious combinations. These findings suggest that clinicians have limited objective criteria for therapeutic decisions for this patient group.

The Spanish National Network "Grupo Castrillo": 22 Years of Nationwide Neonatal Infection Surveillance.

OBJECTIVE: This study aimed to describe the epidemiology of vertically transmitted sepsis (VS) and nosocomial sepsis (NOS) in very low birth weight (VLBW) neonates (birth weight ≤ 1,500 g) over the past 22 years in Spain. STUDY DESIGN: This is a retrospective analysis of prospectively collected VS and NOS in neonates from 1996 to 2018 in the 44 neonatal units integrated in the Spanish Neonatal Network Grupo Castrillo. RESULTS: A total of 2,676 episodes of VS were recorded in 2,196,129 live births (LBs; 1.2/1,000 LBs) over the study period (1996-2018). The incidence declined from 2.4 to 1 to 1.2/1,000 LBs (p < 0.0001). Of the 2,676 episodes, 95.7% were early onset (≤72 hours) and 4.3% cases late onset VS. Group B streptococcus (GBS) (33.1%) and E. coli (29.3%) were the most frequently isolated pathogen. The GBS incidence declined significantly from 1.25 to 0.21/1,000 LBs (p < 0.0001). E. coli incidence showed a significant increase trend in VLBW infants (p < 0.05). The global mortality per 1000 LBs decreased from 0.21 to 0.13/1,000. A total of 7,036 episodes of NOS involving 5,493 VLBW infants were registered over 20,935 neonatal admissions (NAs) in the study period (2006-2018). The incidence was 26.2 per 100 NAs. The median postnatal age at onset was 13 days (interquartile range [IQR]: 9-23 days). Around 80% of cases occurred in infants with a central line in place. Gram positive (GP) bacteria accounted for 66.2% with Staphylococcus epidermidis as the most frequently isolated pathogen, gram negative (GN) bacteria entailed 27.4%, and fungi 6.2%. Klebsiella sp. was the most common GN isolated and Candida albicans the most prevalent fungus. The overall mortality was 8.3%. CONCLUSION: The causative pathogen of neonatal sepsis may change over time and between countries, therefore a national surveillance network based on a consensus definition could be essential to provide accurate information. KEY POINTS: · Grupo Castrillo is a Spanish network for neonatal infections surveillance.. · A neonatal sepsis definition based on epidemilogical and not only chronological criteria was established.. · Epidemiology of neonatal sepsis may change over time; therefore, a national surveillance network is essential to provide accurate information..

Idiopathic granulomatous mastitis: A systematic review of 3060 patients.

Idiopathic granulomatous mastitis is a rare benign breast disease. A systematic review was designed. Clinical and therapeutic characteristics were analyzed. Human Development Index (HDI) was used to define two groups of study: group A (very high and high HDI) and group B (medium and low HDI). Corticosteroid therapy was done in 69% group A and 78% group B. Surgery was done in 63% in group A and 83% in group B. Antibiotics were used in 68% group A and 88% group B. There is no consensus about optimal treatment for granulomatous mastitis.

Rationale and Study Design for an Individualized Perioperative Open Lung Ventilatory Strategy in Patients on One-Lung Ventilation (iPROVE-OLV).

OBJECTIVE: The aim of this clinical trial is to examine whether it is possible to reduce postoperative complications using an individualized perioperative ventilatory strategy versus using a standard lung-protective ventilation strategy in patients scheduled for thoracic surgery requiring one-lung ventilation. DESIGN: International, multicenter, prospective, randomized controlled clinical trial. SETTING: A network of university hospitals. PARTICIPANTS: The study comprises 1,380 patients scheduled for thoracic surgery. INTERVENTIONS: The individualized group will receive intraoperative recruitment maneuvers followed by individualized positive end-expiratory pressure (open lung approach) during the intraoperative period plus postoperative ventilatory support with high-flow nasal cannula, whereas the control group will be managed with conventional lung-protective ventilation. MEASUREMENTS AND MAIN RESULTS: Individual and total number of postoperative complications, including atelectasis, pneumothorax, pleural effusion, pneumonia, acute lung injury; unplanned readmission and reintubation; length of stay and death in the critical care unit and in the hospital will be analyzed for both groups. The authors hypothesize that the intraoperative application of an open lung approach followed by an individual indication of high-flow nasal cannula in the postoperative period will reduce pulmonary complications and length of hospital stay in high-risk surgical patients.

Evaluation of the novel non-invasive zero-heat-flux Tcore™ thermometer in cardiac surgical patients.

Tcore™ Sensor is a novel zero-heat-flux thermometer that estimates core temperature from skin over forehead. We tested the hypothesis that this system estimates core temperature to an accuracy within 0.5 °C. 40 cardiac surgical patients were enrolled (960 measurements). Reference core temperatures were measured in nasopharynx, pulmonary artery and the arterial branch of the oxygenator of the cardiopulmonary bypass (CPB) circuit. 95% Bland-Altman limits of agreement for repeated measurement data was used to study the agreement between Tcore™ thermometer and the reference methods. The proportion of all differences that were within 0.5 °C and Lin's concordance correlation coefficient (LCCC) were estimated as well. The mean overall difference between Tcore™ and nasopharyngeal temperature was - 0.2 ± 0.5 °C (95% limits of agreement of ± 1.09). The proportion of differences within 0.5 °C was 68.80% (95% CI 65.70-71.70%) for nasopharyngeal reference. LCCC was 0.84 (95% CI 0.83-0.86). The mean bias between Tcore™ and the temperature measured in the pulmonary artery was - 0.2 ± 0.5 °C (95% limits of agreement of ± 1.16). 55.30% of measurements were ≤ 0.5 °C (95% CI 51.40-59.20%). LCCC was 0.60 (95% CI 0.56-0.64). The average difference between Tcore™ and the temperature measured at the arterial outlet during the CPB period was - 0.1 ± 0.7 °C (95% limits of agreement of ± 1.43). The proportion of differences within 0.5 °C was 54.40% (95% CI 48.80-60.00%). LCCC was 0.74 (0.69-0.79). Cutaneous forehead zero-flux temperatures were not sufficiently accurate for routine clinical use in the cardiac surgical population.

Educating Engineers for the Public Good Through International Internships: Evidence from a Case Study at Universitat Politècnica de València.

At Universitat Politècnica de València, Meridies, an internship programme that places engineering students in countries of Latin America, is one of the few opportunities the students have to explore the implications of being a professional in society in a different cultural and social context. This programme was analyzed using the capabilities approach as a frame of reference for examining the effects of the programme on eight student participants. The eight pro-public-good capabilities proposed by Melanie Walker were investigated through semi-structured interviews. The internship is an environment in which students can put into practice the knowledge they have acquired in undergraduate studies and to find practical relevance in what they studied. Occasionally, this also entails a critical questioning of what they have learned, a greater awareness of the limits of the contents of their studies and of the way things were taught, and interest in less explored issues that are closely linked to social justice. However, tensions can arise between the pro-public-good oriented perspectives of this programme, and a more instrumental vision. One way to overcome these tensions is to foster consideration of reflexivity, that is, the dynamic relationship between technology and society. To do so, the programme must create space before and during the internship, and upon the return of the students, to discuss and collectively reflect upon their lived experience. Additionally, it ought to engage supervisors in this educational journey, both at the university and in the host institutions, and also involve socially committed organisations in this task.

Iron bioavailability from supplemented formula milk: effect of lactoferrin addition.

PURPOSE: In this work, the absorption and/or bioavailability of iron from two chemical species, 57Fe-Lf (apo-lactoferrin) complex and 57FeSO4 at low and high dose, and in Lf excess were investigated in lactating wistar rats. METHODS: The methodology used is based on the use of stable isotopes in combination with the approach "isotope pattern deconvolution" and ICP-MS for detection. This approach provides quantitative information about exogenous (57Fe) and endogenous iron (natFe) distribution in fluids and tissues in the iron-supplemented rat groups. RESULTS: The observed results with supplemented rats were compared with those found in rats receiving maternal feeding. Interestingly, differences were found between groups in iron for transport and storage compartments, but not in the functional one, depending upon the dose of iron administered and the chemical species. CONCLUSION: Considering the results obtained, supplementation with iron salts in excess of Lf appears to be the best way of iron supplementation of formula milk.

Recommendations on the clinical use of bendamustine in lymphoproliferative syndromes and multiple myeloma.

Bendamustine is an increasingly used hybrid alkylating agent that is active in lymphoid neoplasias via a novel mechanism of action. There are some pending questions about its use in clinical practice because of its developmental features. A consensus panel of several leading Spanish hematologists with broad experience in the clinical use of bendamustine has established recommendations for the management and treatment of hematological patients with bendamustine based on available clinical data and the experience of the participants. These recommendations address the dose and treatment regimen for different clinical indications, the management of toxicity, and support therapy. This article contains the conclusions of this consensus panel, which are intended to serve as guidelines for the use of bendamustine.

Influence of uridine diphosphate-glucuronyltransferase 2B7 (UGT2B7) variants on postoperative buprenorphine analgesia.

BACKGROUND: Genetic factors are known to influence individual differences in pain and sensitivity to analgesics. Different genetic polymorphisms in opioid-metabolizing enzymes that can affect the analgesic response to opioids have been proposed. This study investigates a possible difference in the response to postoperative buprenorphine analgesia related to the presence of different isoforms (cytosine or thymine substitution at nucleotide 802) of UGT2B7 gene. METHODS: Transdermal buprenorphine was administered to 91 patients who underwent muscle-sparing thoracotomy. UGT2B7 polymorphism at locus C802T (His268Tyr) was detected using a PCR Taqman-based procedure. The severity of postoperative pain at rest and during coughing or deep inspiration was assessed by visual analog scale score after surgery. Hospital stay and perioperative opioid consumption were collected. RESULTS: Genotype frequencies were 18.4% for UGT2B7*1/*1, 52.9% for UGT2B7*1/*2, and 28.7% for UGT2B7*2/*2. VAS pain scores at rest were statistically similar among the groups except at 24, 60, and 120 hours (UGT2B7*2/*2 genotype showing higher pain scores). Patients with the UGT2B7*2/*2 genotype showed higher VAS scores triggered by coughing after the 48 hours (P < 0.05). In addition, patients with this genotype reported a higher prevalence of severe pain after 48 postoperative hours (P < 0.05). Thirty-eight percent of patients carrying genotype UGT2B7*2/*2 experienced severe pain in a final survey vs. 17% in the group with UGT2B7*1/*1 (P = 0.36). CONCLUSIONS: The presence of the SNP 802C>T UGT2B7 (UGT2B7*2/*2) is associated with a worse analgesic response to transdermal buprenorphine in the postoperative period of thoracic surgery.

Do chronic myeloid leukemia patients with late "warning" responses benefit from "watch and wait" or switching therapy to a second generation tyrosine kinase inhibitor?

In the latest recommendations for the management of chronic-phase chronic myeloid leukemia suboptimal responses have been reclassified as "warning responses." In contrast to previous recommendations current guidance advises close monitoring without changing therapy. We have identified 198 patients treated with first-line imatinib, with a warning response after 12 months of treatment (patients with a complete cytogenetic response but no major molecular response [MMR]). One hundred and forty-six patients remained on imatinib, while 52 patients changed treatment to a second generation tyrosine kinase inhibitor (2GTKI). Changing therapy did not correlate with an increase in overall survival or progression-free survival. Nevertheless, a significant improvement was observed in the probability of a MMR: 24% vs. 42% by 12 months and 43% vs. 64% by 24 months (P = 0.002); as well as the probability of achieving a deep molecular responses (MR(4.5) ): 1% vs. 17% and 7% vs. 23% by 12 and 24 months, respectively (P = <0.001) .The treatment change to 2GTKI remained safe; however, we have observed a 19% of treatment discontinuation due to side effects. We have observed an improvement of molecular responses after changing treatment to 2GTKI in patients with late suboptimal response treated with imatinib first line. However, these benefits were not correlated with an improvement of progression free survival or overall survival.

Dynamic versus standard bougies for tracheal intubation with direct or indirect laryngoscopy in simulated or real scenarios: a systematic review and meta-analysis.

INTRODUCTION: This systematic review and meta-analysis aimed to compare the efficacy of dynamic versus standard bougies to achieve tracheal intubation. METHODS: We searched MEDLINE, Embase, CENTRAL, Web of Science, Scopus and Google Scholar on 10 October 2023. We included clinical trials comparing both devices. The primary outcome was the first-attempt intubation success rate. The secondary outcome was the time required for tracheal intubation. RESULTS: Eighteen studies were included. Dynamic bougies do not increase first-attempt success rate (RR 1.11; p = 0.06) or shorten tracheal intubation time (MD -0.30 sec; p = 0.84) in clinical trials in humans. In difficult airways, first-attempt success intubation rate was greater for dynamic bougies (RR 1.17; p = 0.002); Additionally, they reduced the time required for intubation (MD -4.80 sec; p = 0.001). First-attempt intubation success rate was higher (RR 1.15; p = 0.01) and time to achieve intubation was shorter when using Macintosh blades combined with dynamic bougies (MD -5.38 sec; p < 0.00001). Heterogeneity was high. CONCLUSION: Dynamic bougies do not increase the overall first-pass success rate or shorten tracheal intubation time. However, dynamic bougies seem to improve first-attempt tracheal intubation rate in patients with difficult airways and in those intubated with a Macintosh blade. Further research is needed for definitive conclusions. REGISTRATION OF PROSPERO: CRD42023472122.

Individualised, perioperative open-lung ventilation strategy during one-lung ventilation (iPROVE-OLV): a multicentre, randomised, controlled clinical trial.

BACKGROUND: It is uncertain whether individualisation of the perioperative open-lung approach (OLA) to ventilation reduces postoperative pulmonary complications in patients undergoing lung resection. We compared a perioperative individualised OLA (iOLA) ventilation strategy with standard lung-protective ventilation in patients undergoing thoracic surgery with one-lung ventilation. METHODS: This multicentre, randomised controlled trial enrolled patients scheduled for open or video-assisted thoracic surgery using one-lung ventilation in 25 participating hospitals in Spain, Italy, Turkey, Egypt, and Ecuador. Eligible adult patients (age ≥18 years) were randomly assigned to receive iOLA or standard lung-protective ventilation. Eligible patients (stratified by centre) were randomly assigned online by local principal investigators, with an allocation ratio of 1:1. Treatment with iOLA included an alveolar recruitment manoeuvre to 40 cm H2O of end-inspiratory pressure followed by individualised positive end-expiratory pressure (PEEP) titrated to best respiratory system compliance, and individualised postoperative respiratory support with high-flow oxygen therapy. Participants allocated to standard lung-protective ventilation received combined intraoperative 4 cm H2O of PEEP and postoperative conventional oxygen therapy. The primary outcome was a composite of severe postoperative pulmonary complications within the first 7 postoperative days, including atelectasis requiring bronchoscopy, severe respiratory failure, contralateral pneumothorax, early extubation failure (rescue with continuous positive airway pressure, non-invasive ventilation, invasive mechanical ventilation, or reintubation), acute respiratory distress syndrome, pulmonary infection, bronchopleural fistula, and pleural empyema. Due to trial setting, data obtained in the operating and postoperative rooms for routine monitoring were not blinded. At 24 h, data were acquired by an investigator blinded to group allocation. All analyses were performed on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, NCT03182062, and is complete. FINDINGS: Between Sept 11, 2018, and June 14, 2022, we enrolled 1380 patients, of whom 1308 eligible patients (670 [434 male, 233 female, and three with missing data] assigned to iOLA and 638 [395 male, 237 female, and six with missing data] to standard lung-protective ventilation) were included in the final analysis. The proportion of patients with the composite outcome of severe postoperative pulmonary complications within the first 7 postoperative days was lower in the iOLA group compared with the standard lung-protective ventilation group (40 [6%] vs 97 [15%], relative risk 0·39 [95% CI 0·28 to 0·56]), with an absolute risk difference of -9·23 (95% CI -12·55 to -5·92). Recruitment manoeuvre-related adverse events were reported in five patients. INTERPRETATION: Among patients subjected to lung resection under one-lung ventilation, iOLA was associated with a reduced risk of severe postoperative pulmonary complications when compared with conventional lung-protective ventilation.

Prognostic factors of mortality in very low-birth-weight infants with neonatal sepsis of nosocomial origin.

OBJECTIVE: To identify the variables associated with sepsis-associated mortality, as well as to develop a severity risk score to predict death in very low-birth-weight (VLBW) neonates affected by nosocomial sepsis. STUDY DESIGN: Retrospective cohort study. Infants weighing ≤ 1500 g with neonatal sepsis of nosocomial origin were included. Epidemiological, clinical, and laboratory variables were recorded at onset (0 hours), at 12 hours, and at 24 hours. Bivariate and multivariate analyses were performed. RESULT: The study population included 95 VLBW infants who presented 129 episodes of nosocomial sepsis. In the bivariate analysis, gram-negative bacilli as the etiology of sepsis, seizures, age, postconceptional age, weight, serum procalcitonin (24 hours), platelet count (24 hours), blood urea nitrogen (0 and 24 hours), creatinine (24 hours), diuresis (12 and 24 hours), mean blood pressure (12 and 24 hours), pH, base excess (0, 12, and 24 hours), and SpO(2) (pulse oximetric saturation):F(IO(2)) (fraction of inspired oxygen) ratio (12 and 24 hours) were significantly associated with mortality. In the multivariate analysis, weight at the onset of sepsis, base excess (0 hours), and SpO(2):F(IO(2)) ratio (12 hours) were independent predictors of mortality. CONCLUSION: A lower weight at the onset of sepsis, base excess, and SpO(2):F(IO(2)) ratio are useful to predict nosocomial sepsis-associated mortality in VLBW infants.

[Prevention of Neonatal Group B Sreptococcal Infection. Spanish Recommendations. Update 2012.

Documento de consenso SEIMC/SEGO/SEN/SEQ/SEMFYC.

Group B streptococci (GBS) remain the most common cause of early onset neonatal sepsis. In 2003 the Spanish Societies of Obstetrics and Gynaecology, Neonatology, Infectious Diseases and Clinical Microbiology, Chemotherapy, and Family and Community Medicine published updated recommendations for the prevention of early onset neonatal GBS infection. It was recommended to study all pregnant women at 35-37 weeks gestation to determine whether they were colonised by GBS, and to administer intrapartum antibiotic prophylaxis (IAP) to all colonised women. There has been a significant reduction in neonatal GBS infection in Spain following the widespread application of IAP. Today most cases of early onset GBS neonatal infection are due to false negative results in detecting GBS, to the lack of communication between laboratories and obstetric units, and to failures in implementing the prevention protocol. In 2010, new recommendations were published by the CDC, and this fact, together with the new knowledge and experience available, has led to the publishing of these new recommendations. The main changes in these revised recommendations include: microbiological methods to identify pregnant GBS carriers and for testing GBS antibiotic sensitivity, and the antibiotics used for IAP are updated; The significance of the presence of GBS in urine, including criteria for the diagnosis of UTI and asymptomatic bacteriuria in pregnancy are clarified; IAP in preterm labour and premature rupture of membranes, and the management of the newborn in relation to GBS carrier status of the mother are also revised. These recommendations are only addressed to the prevention of GBS early neonatal infection, are not effective against late neonatal infection.

Disinfection of Reusable Laryngoscopes: A Survey about the Clinical Practice in Spain.

Airway device-associated infections resulting from the cross-contamination of reusable laryngoscopes are one of the main causes of healthcare-associated infections. Laryngoscope blades are highly contaminated with various pathogens, including Gram-negative bacilli, which can cause prolonged hospitalization, high morbidity and mortality risks, the development of antibiotic-resistant microorganisms, and significant costs. Despite the Centers for Disease Control and Prevention and the American Society of Anesthesiologists' recommendations, this national survey of 248 Spanish anesthesiologists showed that there is great variability in the processing of reusable laryngoscopes in Spain. Nearly a third of the respondents did not have an institutional disinfection protocol, and 45% of them did not know the disinfection procedure used. Good practices for the prevention and control of cross-contamination can be ensured through compliance with evidence-based guidelines, education of healthcare providers, and audits of clinical practices.
