Effect of UV-C disinfection and copper plating on healthcare-associated infections in a NICU with high ESBL infections.

INTRODUCTION: Healthcare-associated infections (HCAIs) in neonates are frequent and highly lethal, in particular those caused by extended spectrum beta-lactamase (ESBL) producing bacteria. We evaluated the beneficial effects of ultraviolet C (UV-C) disinfection and copper adhesive plating on HCAIs in the Neonatal Intensive Care Unit (NICU) of a third level paediatric hospital in Mexico City, both in combination of hand-hygiene (HH) and prevention bundles. METHODS: All NICU patients were included. There were 4 periods (P): P1: HH monitoring and prevention bundles; P2: P1+UV-C disinfection; P3: P2+Copper adhesive plating on frequent-contact surfaces and P4: Monitoring of P3 actions. RESULTS: 552 neonates were monitored during 15,467 patient days (PD). HCAI rates decreased from 11.03/1000 PD in P1 to 5.35/1000 PD in P4 (p=0.006). HCAIs with bacterial isolates dropped from 5.39/1000 PD in PI to 1.79/1000 PD in P4 (p=0.011). UV-C and copper were associated with significant HCAI prevention (RR 0.49, CI95% 0.30-0.81, p=0.005) and with lesser HCAIs with bacterial isolates (RR 0.33, CI95% 0.14-0.77, p=0.011). CONCLUSIONS: Copper adhesive plating combined with UV-C disinfection were associated with a drop in HCAI rates and with the elimination of ESBL-caused HCAIs. Hence, we propose that these strategies be considered in MDRO proliferation preventions.

Diagnostic support in pediatric craniopharyngioma using deep learning.

PURPOSE: We studied a pediatric group of patients with sellar-suprasellar tumors, aiming to develop a convolutional deep learning algorithm for radiological assistance to classify them into their respective cohort. METHODS: T1w and T2w preoperative magnetic resonance images of 226 Chilean patients were collected at the Institute of Neurosurgery Dr. Alfonso Asenjo (INCA), which were divided into three classes: healthy control (68 subjects), craniopharyngioma (58 subjects) and differential sellar/suprasellar tumors (100 subjects). RESULTS: The PPV among classes was 0.828±0.039, and the NPV was 0.919±0.063. Also explainable artificial intelligence (XAI) was used, finding that structures that are relevant during diagnosis and radiological evaluation highly influence the decision-making process of the machine. CONCLUSION: This is the first experience of this kind of study in our institution, and it led to promising results on the task of radiological diagnostic support based on explainable artificial intelligence (AI) and deep learning models.

Efecto del pulso de inundación sobre el ensamble de ostrácodos (Ostracoda: Podocopida) en microambientes en la Ciénaga Río Viejo, Colombia / Effect of the flood pulse on the ostracod assemblage (Ostracoda: Podocopida) in microenvironments in the Ciénaga Río Viejo, Colombia

Resumen Introducción: Las ciénagas hacen parte de la llanura de inundación de un río y son influenciadas por el pulso de inundación, fuerza que modula los cambios anuales en las variables bióticas y abióticas. Los ensambles biológicos tienen diferentes respuestas a este pulso y podrían presentar cambios en la composición y abundancia. Objetivo: Evaluar cómo se modifican las condiciones físico-químicas en los microambientes de vegetación flotante y el ensamble de ostrácodos a lo largo de un pulso de inundación en la Ciénaga Río Viejo, Santander, Colombia. Métodos: Se caracterizaron las variables físico-químicas de los microambientes de plantas acuáticas flotantes durante las cuatro fases hidrológicas del pulso de inundación: aguas bajas, altas, ascenso y descenso, en tres estaciones donde el pulso tuvo mayor efecto. Ostrácodos dulceacuícolas fueron recolectados de estos microambientes, identificados y contados. Resultados: Las condiciones ambientales dentro de los microhábitats fluctuaron siguiendo el pulso de inundación en el sistema. Se encontraron tres familias taxonómicas y seis especies de ostrácodos. No hubo diferencias en la composición y abundancia del ensamble de ostrácodos en el espacio y el tiempo, lo que sugiere que están protegidas contra los cambios ambientales causados por las fluctuaciones hidrológicas. La abundancia de especies cambió en respuesta a la variabilidad ambiental. Strandesia cf. sphaeroidea y Keysercypria sp. 2 están asociadas con aguas más someras y con mayor cobertura de vegetación acuática densa. Otras especies mostraron ser tolerantes a fluctuaciones hidrológicas y pueden estar relacionadas con la plasticidad ecológica, como Cytheridella ilosvayi, Diaphanocypris meridana y Stenocypris major, que han sido registradas en una variedad de ambientes acuáticos y con distribuciones a escala continental. Conclusiones: Los pulsos de inundación indujeron cambios ambientales en la Ciénaga de Río Viejo, pero los microhábitats con cobertura de vegetación flotante parecen estar protegidos contra el pulso hidrológico, permitiendo así que las comunidades de ostrácodos permanezcan casi sin alteraciones durante un pulso de inundación. Este conjunto de datos actualizado de agua dulce tropical contribuye a llenar los vacíos de conocimiento relacionados con la idoneidad del hábitat y la distribución de las comunidades de ostrácodos en Colombia.

Abstract Introduction: Swamps are lowland shallow tropical lakes in rivers floodplains, characterized by annual flood pulses that modulate changes in biotic and abiotic variables. Biological assemblages have different responses to flood pulses, remaining either undisturbed or with significant changes in composition and abundance. Objective: To evaluate how physical and chemical conditions are modified in mixed macrophytes microenvironments and ostracod species assemblages throughout a flood pulse in Rio Viejo swamp, Santander, Colombia. Methods: We characterized physical and chemical variables of microenvironments of aquatic floating plants, during four different hydrologic periods of the flood pulse: low, high, rising, and descending waters, at three stations where the flood pulse have the most important effect. Freshwater ostracods were collected from such microenvironments, identified, and counted. Results: Environmental conditions within microhabitats fluctuated following the flood pulse in the system. Three taxonomic families and six species of ostracods were observed. No differences in the composition and abundance of the spatio-temporal ostracod assemblages were observed, suggesting that they are buffered against environmental changes driven by hydrological fluctuations. Species abundance changed in response to environmental variability. Species such as Keysercypria sp. and Keysercypria sp. 2 are associated to shallower waters and more likely to dense aquatic vegetation cover. Other species showed to be more tolerant to hydrological fluctuations and may be related to ecological plasticity, species such as Cytheridella ilosvayi, Diaphanocypris meridana and Stenocypris major that have been recorded in a variety of aquatic environments and with distributions at continental scale. Conclusions: Flood pulses induced environmental changes in Rio Viejo Swamp, but microhabitats in mixed macrophyte cover seems to be buffered against the hydrological pulse, thus allowing almost undisturbed ostracod assemblages throughout a flood pulse. This updated tropical freshwater dataset contributes towards filling the knowledge gaps related to habitat suitability and distribution of ostracods communities in Colombia.

Therapeutic effect of α7 nicotinic receptor activation after ischemic stroke in rats.

Nicotinic acetylcholine α7 receptors (α7 nAChRs) have a well-known modulator effect in neuroinflammation. Yet, the therapeutical effect of α7 nAChRs activation after stroke has been scarcely evaluated to date. The role of α7 nAChRs activation with PHA 568487 on inflammation after brain ischemia was assessed with positron emission tomography (PET) using [18F]DPA-714 and [18F]BR-351 radiotracers after transient middle cerebral artery occlusion (MCAO) in rats. The assessment of brain oedema, blood brain barrier (BBB) disruption and neurofunctional progression after treatment was evaluated with T2 weighted and dynamic contrast-enhanced magnetic resonance imaging (T2 W and DCE-MRI) and neurological evaluation. The activation of α7 nAChRs resulted in a decrease of ischemic lesion, midline displacement and cell neurodegeneration from days 3 to 7 after ischemia. Besides, the treatment with PHA 568487 improved the neurofunctional outcome. Treated ischemic rats showed a significant [18F]DPA-714-PET uptake reduction at day 7 together with a decrease of activated microglia/infiltrated macrophages. Likewise, the activation of α7 receptors displayed an increase of [18F]BR-351-PET signal in ischemic cortical regions, which resulted from the overactivation of MMP-2. Finally, the treatment with PHA 568487 showed a protective effect on BBB disruption and blood brain vessel integrity after cerebral ischemia.

Hepatitis C virus micro-elimination in vulnerable populations before and during a global pandemic.

OBJECTIVE: to analyze a hepatitis C virus (HCV) microelimination strategy targeting vulnerable populations and the influence of the pandemic on its maintenance and outcomes. METHODS: in 2018, the Hepatology Unit implemented an HCV microelimination strategy for patients attending drug addiction care centers and Psychiatry Units such as the Alcoholism Treatment Unit. These centers reported suspected or confirmed cases of HCV infection directly to the hepatologists, who, after reviewing the clinical records, cite those patients if necessary. RESULTS: from June 2018 to February 2020, hepatologists were consulted on 37 anti-HCV positive patients, 31 of them were from Drug Addiction Care Centers, 5 from the Alcoholism Disorders Unit and 1 from the Department of Psychiatry. Fibrosis stage: F0-F1, 18 (50%); F2, 9 (25%); F3, 2 (4.2%); F4, 8 (20.8%). Female sex, 6 (16.7%). Required attending: Yes, 27 (73%). 25 (92.6%) went. Outpatient consultation: 10 (27%). Required treatment: 19 (51.3%). Sustained virological response: 19 (100%). Fibrosis stage of treated patients: F0-F1, 13 (68%); F2, 2 (11%); F3, 1 (5%); F4, 3 (16%). Patients from the Psychiatry Department during 2021: 11. 9 (82%) do not need to attend; 2 (18%): their situation is unknown. CONCLUSIONS: sustained communication with centers that care for populations at risk of active HCV infection is needed to detect cases, increase adherence to treatment, and rescue patients who require screening for hepatocarcinoma.

Exclusive breastfeeding abandonment in adolescent mothers: a cohort study within health primary services.

OBJECTIVE: to analyze the factors associated with the abandonment of exclusive breastfeeding in adolescent mothers during the first 6 months of the infant's life. METHOD: this is a cohort study of 105 adolescent mothers followed at the child's 2-, 4- and 6-months of age. The epidemiological approach was adopted, supported by the positivism paradigm. Exposure variables were those directly related to breastfeeding and sociodemographic, family, maternal and child conditions. Data were collected by interview and analyzed by bivariate and multivariate statistics. The Hazard Ratio (HR) was calculated with a 95% confidence interval (95%CI). The tests were performed, admitting an error type I of 5%. The confidentiality of data was ensured. RESULTS: the cumulative incidences of exclusive breastfeeding abandonment were 33.3%, 52.2% and 63.8%, at 2, 4 and 6 months, respectively. The variables that remain in the final multivariate model were maternal perception of milk quality (HR=11.6; 95%CI 3.6-37.5), pacifier use (HR=1.9; 95%CI 1.2-3.3), and time of first breastfeeding session (HR=1.4; 95%CI 0.5-12.9). CONCLUSION: the highest abandonment rate occurs before the fourth month. A perception of having poor-quality milk by the adolescent mother and pacifier use are factors that favor the abandonment of exclusive breastfeeding. Determining the factors associated with breastfeeding abandonment may allow their timely management, especially in more vulnerable populations. KEYPOINTS: (1) The highest abandonment rate of exclusive breastfeeding occurs before the fourth month. (2) A perception of having poor-quality milk may increase the abandonment of exclusive breastfeeding. (3) Pacifier use may increase the abandonment of exclusive breastfeeding. (4) Knowing the factors associated with exclusive breastfeeding may allow for timely management of them. (5) Exclusive breastfeeding promotion strategies must be adopted early, before and after birth.

Effects of Carbonated Beverage Consumption on Oral pH and Bacterial Proliferation in Adolescents: A Randomized Crossover Clinical Trial.

Sugary soft drinks modify salivary pH and favor bacterial proliferation and are associated with the development of caries. Information on the effects of consuming carbonated drinks without sucrose is limited. Methods: In this crossover clinical trial, salivary and dental biofilm pH were determined at 0, 5, 10, 15, 30, 45, and 60 min after the participants (n = 18) ingested a soft drink with sucrose, a soft drink with aspartame/acesulfame K, carbonated water, and plain water on different days. Dental biofilm cultures were conducted at 0- and 120-min. Results: Salivary pH decreased significantly after ingestion of the sucrose-containing soft drink when compared with the other types of beverages (median difference, -0.3--0.4, p ≤ 0.05), and the greatest difference was found with mineral water. A greater bacterial proliferation (Colony Forming Units [CFU]) was observed after ingestion of the drink with sucrose (↑310 × 103 CFU, p ≤ 0.01), followed by the drink with aspartame/acesulfame K (↑160 × 103 CFU, p ≤ 0.01) and carbonated water (↑60 × 103 CFU, p ≤ 0.05). No significant changes in bacterial proliferation were observed after the consumption of natural water. Conclusions: Ingestion of sucrose-containing soft drinks favors the acidification of salivary pH and the bacterial proliferation of dental biofilm. Although to a lesser extent, soft drinks containing aspartame/acesulfame K also favor bacterial proliferation.

Quality of life against seasonal vs perennial allergens: ESPRINT-15 modified in the pediatric population.

INTRODUCTION: Allergic rhinitis (AR) is a clinical syndrome characterized by IgE-mediated inflammation of the nasal mucosa. The present study investigates the quality of life (QoL) with AR among adults, using widely validated questionnaires, unlike in pediatric patients. MATERIALS AND METHODS: A cross-sectional descriptive observational study was conducted, analyzing the QoL of 102 children with AR aged between 10-15 years, belonging to two health centers (HC) in Zaragoza and two HC in Coruña. The comparison of means between the two groups is carried out using the Student's test or the Mann-Whitney test, considering a value of p˂0.05 to be significant. RESULTS: Around 102 children were studied, with a majority (59.8%) being male and a mean age of 12 years. Around 76.5% have a family history of atopy. It was found that AR is more prevalent in Zaragoza (p ˂0.005), and asthmais highly prevalent in Coruña (p ˂0.001). The most important sensitizations are pollen in Zaragoza (p ˂0.05) and dust mites in A Coruña (p ˂0.001). More treatment needs and associated comorbidities (p˂0.05) were observed in A Coruña. The results of the ESPRINT-15 show that 63% of the patients have a good QoL, 27% fair, and 8.8%, poor. Those sensitized to mites have a worse score (p = 0.02). It was found that 52% of children experienced improvement during home confinement, with no notable differences between the two populations. The use of the mask favored QoL in patients from Zaragoza (p ˂0.001). CONCLUSION: It was concluded that AR influences the QoL in pediatric patients. Greater QoL involvement, need for treatment, and comorbidities are observed in patients sensitized to dust mites compared to those sensitized to pollens. It was also observed that masks improved the symptoms, stopping patients being sensitized to pollens.

Employees' emotional awareness as an antecedent of organizational commitment-The mediating role of affective commitment to the leader.

Commitment has been perceived as a strategic topic in organizations due to its positive effect on retaining talent, increasing performance, or boosting employees' innovative behavior. However there are many focis of commitment in the workplace, which has represented a challenge to human resources management, who need implement measures to improve the employee's commitment. Recent research has suggested a need to conduct studies about commitment, namely antecedents and the relationship between different focis, to understand the dynamic and directionality between them. Hence, the purpose of this work is to analyze how employees' emotional awareness relates with two focis of commitment (the leader and the organization), also assessing the mediating role of affective commitment to the leader. The study uses structural equation modeling and Lisrel to test the hypotheses considering the multidimensionality of organizational commitment (affective; normative; and continuance), employees emotional awareness (understanding self-emotions; self-control when facing criticism; and understanding others' emotions), and the affective commitment to the leader, under the scope of Social Exchange Theory. The Mackinon's Z Test was used to assess the mediation role of affective commitment to the leader. The sample is composed for 403 employees from two multinational companies. The results provide empirical evidence about the mediating role of affective commitment to the leader in the relationship between employees' emotional awareness and organizational commitment, and the employees' emotional awareness as an antecedent of commitment. The implications for theory and practice are discussed.

Analysis of the Emotional Exhaustion Derived From Techno-Stress in the Next Generation of Qualified Employees.

This study analyses the emotional exhaustion of students inhigher education, derived from the extremely technology-relatedstrain associated to the current COVID-19 pandemic in a conservation of resources' approach. Technostress, as source of emotional exhaustion, was investigated in a sample of 333 students in a medium size public university in Spain. Data was collected in May 2020, during the COVID lockdown. After literature review, a structural model was developed, linking technostress with emotional exhaustion. Results confirm the expected cause-effect relationships. In addition, the study reveals two mediator variables that must be considered when managing students' suffering, perceived stress and intrapersonal conflicts. This study contributes to the academic literature in the field of managing and mitigating suffering. They do so by providing both new knowledge and empirical evidence on the effects of technostress in the new generations that will soon join the working life.

Profile of Daughters and Sisters of Women With Polycystic Ovary Syndrome: The Role of Proband's Glucose Tolerance.

CONTEXT: First-degree relatives of women with polycystic ovary syndrome (PCOS) present hormonal and metabolic alterations compared to girls unrelated to PCOS. It is unknown whether glucose intolerance in the PCOS proband confers a more severe metabolic predisposition on their first-degree relatives. OBJECTIVE: To determine whether glucose tolerance status in women with PCOS is associated with worsened glucose metabolism and sex hormone levels in their peripubertal daughters or sisters. DESIGN: Cross-sectional study. SETTING: Seven academic centers in North America, South America, and Europe. PATIENTS: Sixty-four pairs of women with PCOS and their daughters or younger sisters aged between 8 and 14 years were recruited. Twenty-five mothers or older sisters with PCOS were glucose intolerant (GI) and 39 were normal glucose tolerant (NGT). MAIN OUTCOME MEASURES: Beta-cell function estimated by the insulin secretion-sensitivity index-2 (ISSI-2) during an oral glucose tolerance test and by the disposition index during a frequently sampled IV glucose tolerance test. Free testosterone and 17-hydroxyprogesterone (17-OHP) levels. RESULTS: Being related to a GI PCOS proband was associated with a lower ISSI-2 (P-value = 0.032) after adjusting for ethnicity, body mass index z-score, and pubertal stage. They also had higher free testosterone (P-value = 0.011) and 17-OHP levels compared to girls with an NGT proband, the latter becoming significant after adjusting for confounders (P-value = 0.040). CONCLUSIONS: Compared to first-degree female relatives of women with PCOS and NGT, first-degree relatives of women with PCOS and GI display lower beta-cell function and hyperandrogenemia, putting them at higher risk of GI and PCOS development.

Biomechanical Analysis of Cervical Motion With a Pediatric Immobilization and Extrication Device.

OBJECTIVE: To determine the motions produced during pediatric extrication when using a system of motion estriction and extrication. METHODS: Simulation-based biomechanical analysis study conducted with inertial sensors to measure motion produced in the cervical spine of a pediatric simulator during extrication from a vehicle. RESULTS: The mean of the movements was 3.5° (SD ±1.35°). The mean time was 4 minutes 1 second (SD, ±45.09 seconds). The mean rotation toward the right was 3.34° (SD ±3.52°) and toward the left 2.62° (SD ±2.26°). The mean for lateralization was 6.24° (SD ±3.20°) toward the right and 2.50° (DE ±2.76°) toward the left. The mean for flexion was 2.36° (SD ±2.10°) and for extension 4.21° (SD ±2.15°). CONCLUSIONS: The device analyzed allows for the extrication of the pediatric patient with high levels of motion restriction of the spinal column with the Pediatric Immobilization and Extrication System.

Resumo Objetivo: analisar os fatores associados ao abandono do aleitamento materno exclusivo em mães adolescentes durante os primeiros seis meses de vida do bebê. Método: trata-se de um estudo de coorte com 105 mães adolescentes acompanhadas aos dois, quatro e seis meses de vida de seus filhos. Uma abordagem epidemiológica, apoiada por um paradigma positivista, foi adotada. As variáveis de exposição escolhidas foram aquelas diretamente relacionadas ao aleitamento materno e a condições sociodemográficas, familiares, maternas e infantis. Os dados usados foram coletados através de entrevistas e analisados por estatísticas bivariadas e multivariadas. A razão de risco (RR) foi calculada com um intervalo de confiança de 95% (IC95%). Os testes foram realizados, admitindo um erro tipo I de 5%. A confidencialidade dos dados foi garantida. Resultados: as incidências acumuladas de abandono do aleitamento materno exclusivo foram de 33,3%, 52,2% e 63,8%, aos dois, quatro e seis meses de vida dos bebês, respectivamente. As variáveis que permaneceram no modelo multivariado final foram percepção materna da qualidade de seu leite (HR=11,6; 95% IC 3,6-37,5), uso de chupeta (HR=1,9; 95% IC 1,2-3,3) e tempo de primeira sessão de aleitamento materno depois do nascimento (HR=1,4; 95% IC 0,5-12,9). Conclusão: a maior taxa de abandono ocorre antes do quarto mês de vida dos bebês. Mães adolescentes que julgaram seu leite como ruim e bebês que usam chupeta são fatores que favorecem o abandono do aleitamento materno exclusivo. A determinação dos fatores associados ao abandono do aleitamento materno pode permitir sua gestão oportuna, especialmente em populações mais vulneráveis.

Clinical and genetic characteristics in patients under 30 years with sporadic pituitary adenomas.

OBJECTIVE: Pituitary adenomas (PA) are rare in young patients, and additional studies are needed to fully understand their pathogenesis in this population. We describe the clinical and genetic characteristics of apparently sporadic PA in a cohort of young patients. DESIGN: Clinical and molecular analysis of 235 patients (age ≤ 30 years) with PA. Clinicians from several Spanish and Chilean hospitals provided data. METHODS: Genetic screening was performed via next-generation sequencing and comparative genomic hybridization array. Clinical variables were compared among paediatric, adolescent (<19 years) and young adults' (≥19-30 years) cohorts and types of adenomas. Phenotype-genotype associations were examined. RESULTS: Among the total cohort, mean age was 17.3 years. Local mass effect symptoms were present in 22.0%, and prolactinomas were the most frequent (44.7%). Disease-causing germline variants were identified in 22 individuals (9.3%), more exactly in 13.1 and 4.7% of the populations aged between 0-19 and 19-30 years, respectively; genetically positive patients were younger at diagnosis and had larger tumour size. Healthy family carriers were also identified. CONCLUSIONS: Variants in genes associated with syndromic forms of PAs were detected in a large cohort of apparently sporadic pituitary tumours. We have identified novel variants in well-known genes and set the possibility of incomplete disease penetrance in carriers of MEN1 alterations or a limited clinical expression of the syndrome. Despite the low penetrance observed, screening of AIP and MEN1 variants in young patients and relatives is of clinical value.

Encountering Suffering at Work in Health Religious Organizations: A Partial Least Squares Path Modeling Case-Study.

Health religious organizations tend to offer individual attention to patients in line with their spiritual character and, at the same time, the highest service quality. This study puts the attention on the nurse-patient relationship and empirically explores a theoretical model that links nurses' suffering at work with personal's willingness to engage in a therapeutic and spiritual relationship with patients and the consequent effect on quality. Data has been collected in the city of Madrid (Spain) in the month of June 2019 in Santa Elena Clinic. An analytical case-study based on Partial Least Squares (PLS) path modeling is the chosen method to verify the cause-effect hypothesized relationships. This study contributes to the current academic literature by providing new knowledge and empirical evidence on the topic of the future of work in health religious organizations. The main conclusion is the necessary inclusion of suffering, even in good places to work, as a key indicator for a better management. Results should be a useful source of information for practitioners that seek to implement better human management systems in these organizations.
