Correlation of Blood Hemoglobin Values with Non-Invasive Co-Oximetry Measurement of SpHb in Dogs Undergoing Elective Ovariohysterectomy.

Cardiovascular function monitoring has been suggested as a key parameter to determine patient stability during the anesthetic process. However, the use of pulse co-oximetry has been suggested as a technology to complement the monitoring of this system as a direct way to assess hemoglobin (Hb) blood concentration. Therefore, this study aimed to correlate and determine the measurement bias between Hb blood levels with continuously determined blood hemoglobin concentration (SpHb) and arterial oxygen content values (SpOC), both obtained by noninvasive co-oximetry in dogs undergoing elective ovariohysterectomy (OVH). A total of 85 clinically healthy bitches of different breeds that were admitted for elective OVH surgery were evaluated. These animals underwent SpHb and SpOC capture after the in vivo setting for the duration of the surgical procedure. Likewise, five minutes before the end of the surgical procedure, a blood sample was obtained directly from the jugular vein to determine the blood concentration of Hb (HbLAB). The Bland-Altman analysis showed 95% limits of agreement from -4.22 to 4.99 g/dL with a BIAS (mean difference) of 0.384 ± 2.35 g/dL (r = 0.401). SpHb recordings were correlated with oxygen saturation (SpO2) (r = 0.995), SpOC (r = 0.992) and with perfusion index (PI) (r = 0.418). Therefore, SpHb presents a moderate positive correlation with direct blood concentration of Hb. This possibly shows that continuous measurement of SpHb by noninvasive co-oximetry is a reliable and advanced alternative for monitoring Hb concentration in dogs under anesthesia.

Anticaries properties of natural berries: systematic literature review.

CONTEXT: Anticariogenic properties have been ascribed to polyphenolic compounds present in high concentrations in numerous fruits. Berries, in particular, have been reported as potentially having an inhibitory effect on the dental biofilm and subsequently on caries, but the evidence is unclear. OBJECTIVE: The objective of this review was to explore the literature and summarize the evidence for berries having an inhibitory effect on the dental biofilm and an anticariogenic effect. DATA SOURCES: Following Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, the PubMed, Web of Science, and SCOPUS databases were scanned using predefined and accessible terms, with a search strategy based on a structured PICO question. DATA EXTRACTION: After article selection, 23 studies met the inclusion criteria, most of them being in vitro studies. A risk assessment was performed, and data were extracted and presented in a table for qualitative analysis. DATA ANALYSIS: Meta-analyses were conducted using standardized mean differences (SMDs) with a 95% confidence interval (CI) by Review manager 5.4. RESULTS: Only 3 types of berries were found to have a reported anticaries effect: grape seed extract (GSE), cranberry, and sour cherry. Nine studies that fulfilled the eligibility criteria were subjected to quantitative analysis. Meta-analyses showed GSE was associated with enhanced remineralization of dental enamel (SMD = .96 95% CI [.45, 1.46], P < .0002) and of dentin (SMD = .65 95% CI [.13, 1.17], P = .01). Cranberry extracts positively influenced the cariogenic dental biofilm by decreasing the biofilm biomass (SMD = -2.23 95% CI [-4.40, -.05], P = .04), and biovolume (SMD = -2.86 95% CI [-4.34, -1.37], P = .0002), and increasing the biofilm pH (SMD = 7.9 95% CI [3.49, 12.31], P < .0004). CONCLUSION: Within the limitations of this systematic review and metaanalysis, GSE and cranberries or their active compounds could represent an alternative for caries management. Further clinical trials are needed to verify this effect in a clinical setting. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42020223579.

Sedation level with midazolam: A pediatric surgery approach.

Midazolam (MDZ) is a short-acting benzodiazepine that is widely used to induce and maintain general anesthesia during diagnostic and therapeutic procedures in pediatric patients due to its sedative properties. The aim of this study was to perform a systematic review without a meta-analysis to identify scientific articles and clinical assays concerning MDZ-induced sedation for a pediatric surgery approach. One hundred and twenty-eight results were obtained. After critical reading, 37 articles were eliminated, yielding 91 publications. Additional items were identified, and the final review was performed with a total of 106 publications. In conclusion, to use MDZ accurately, individual patient characteristics, the base disease state, comorbidities, the treatment burden and other drugs with possible pharmacological interactions or adverse reactions must be considered to avoid direct alterations in the pharmacokinetics and pharmacodynamics of MDZ to obtain the desired effects and avoid overdosing in the pediatric population.

Food Loss and Waste Actions: Experiences of the Costa Rican Food Loss and Waste Reduction Network.

Food Loss and Waste (FLW) reduction and prevention can be crucial entry points to achieve sustainable food systems. However, the complexity of this problem poses the need for multistakeholder and multidimensional approaches. The Costa Rican FLW Reduction Network has been working since 2014 as a collaborative platform that brings together different sectors and disciplines to promote a change through communication and awareness, alliances, and research and innovation. The purpose of our study was to share the experience of Costa Rica in regards to the applied FLW actions and its catalytic effect on FLW innovation. The study was developed through a multimethod approach that included case studies, stakeholder analysis and literacy analysis to provide an overall assessment of the strategy as input for further efforts in this matter. The main findings indicate that collaborative actions among institutions and sectors are vital in promoting FLW reduction; however, FLW innovation is still at an inception phase where financial resources and policy barriers remain as aspects to address. In conclusion, the Costa Rica FLW Network represents an asset to trigger ongoing and future actions, and approaches like an integrated innovation ecosystem must be promoted.

Unveiling the social performance of selected agri-food chains in Costa Rica: the case of green coffee, raw milk and leafy vegetables.

PURPOSE: Several frameworks coincide in the importance of addressing social impacts to ensure sustainability. However, the agri-food sector, regarded as key in sustainable production, still neglects to identify potential social impacts when applying life cycle approaches. This work contributes to understanding the social performance of three agricultural products from a Latin American and Caribbean developing country as Costa Rica while recognising the challenges of Social-Life Cycle Assessment (S-LCA) application in this context. METHODS: S-LCA represents a powerful technique to evaluate the potential social impacts of a product. Three case studies were analysed through S-LCA, using the subcategory assessment method (SAM) to characterise the social impacts and detect hotspots in the production of green coffee, raw milk and leafy vegetables. Primary data was collected through questionnaires to relevant informants and observations. In addition to secondary information, these data and information were used to assess eight impact subcategories for the farmer and worker stakeholder groups and nine subcategories for the local community. RESULTS AND DISCUSSION: The main results suggest that the Costa Rican institutional and market frameworks provide an enabling environment for a generally positive social performance in the studied cases. The assessed stakeholders can fulfil basic needs through access to inputs and services and achieve fair-trading conditions. Child labour, forced labour and evidence of environmental or health risks for the surrounding communities were absent. Important efforts to address the delocalisation, migration and child labour were observed, suggesting the potential development of social handprints in further studies. However, the farm production phase, related to farmers and workers, entails hotspots regarding social security and women's empowerment. Moreover, farmers appear as the most vulnerable group because of their overall social performance. CONCLUSIONS: S-LCA helped identify relevant areas of intervention in the context of these particular case studies; however, further research and capacity building are recommended to tackle the detected challenges, both in the agri-food chains and in the use of S-LCA. Furthermore, these findings can aid in future decision and policy-making to improve and safeguard the positive social performance observed in the studied products.

Cybervictimization, Depression, Suicidal Ideation, and Addictive Behavior toward Social Media / Cibervictimización, Depresión, Ideación Suicida, y Comportamiento Adictivo hacia Redes Sociales

Abstract An addictive behavior is considered to exist when there is excessive use, loss of control and tolerance, and withdrawal symptoms which cause negative repercussions in everyday life and become a concern where other psychopathological problems may manifest. The objective of this study was to develop an explanatory model of cybervictimization, depression, suicidal ideation and addictive behavior toward social media. Instruments that measured these variables were applied to a total sample of 406 university students. A significant correlation was found between addictive behavior toward social media, cybervictimization, depression, and suicidal ideation. The model explained that cybervictimization and depression can lead to two outcomes: an addictive behavior toward social media, or suicidal thoughts. These results contribute to a better understanding of current phenomenon such as cybervictimization and addictive behavior toward social media with respect to depression and suicidal ideation. A deeper investigation is recommended to create preventive and intervention programs for healthy Internet usage for young people.

Resumen Se considera que existe un comportamiento adictivo cuando hay un uso excesivo, pérdida de control y tolerancia, y síntomas de abstinencia que causan repercusiones negativas en la vida cotidiana y se convierten en una preocupación donde pueden manifestarse otros problemas psicopatológicos. El objetivo de este estudio fue desarrollar un modelo explicativo de cibervictimización, depresión, ideación suicida y comportamiento adictivo hacia las redes sociales. Los instrumentos que midieron estas variables se aplicaron a una muestra total de 406 estudiantes universitarios. Se encontró una correlación significativa entre el comportamiento adictivo hacia las redes sociales, la cibervictimización, la depresión y la ideación suicida. El modelo explicó que la cibervictimización y la depresión pueden conducir a dos resultados: un comportamiento adictivo hacia las redes sociales o pensamientos suicidas. Estos resultados contribuyen a una mejor comprensión del fenómeno actual, como la cibervictimización y el comportamiento adictivo hacia las redes sociales con respecto a la depresión y la ideación suicida. Se recomienda una investigación más profunda para crear programas preventivos e de intervención para el uso saludable de Internet para los jóvenes.

Percepción de enfermería respecto a la atención hospitalaria otorgada a personas que viven con VIH / Percepção da enfermagem em relação a atenção hospitalar dada para pessoas que vivem com HIV / Nursing perception regarding the attention given in hospitals to patients that live with HIV

Resumen: Dado el contexto epidemiológico en Chile referente al alza de la cantidad de personas con VIH, cobra relevancia el fortalecimiento del cuidado otorgado a estos pacientes. Por esto, el objetivo de esta investigación es conocer la percepción de enfermeras(os) respecto a la atención otorgada a personas que viven con VIH (PVVIH) en un servicio hospitalario de atención terciaria de salud, buscando contribuir a la enfermería. Para ello se utilizó un paradigma de investigación cualitativo tipo estudio de caso, recolectando la información con una entrevista semiestructurada, finalizando con un análisis del discurso de tipo semiótico. Se destacó que en las primeras atenciones se generaba "temor" en la atención a PVVIH, el que desaparecía a medida que aumentaban los conocimientos de la profesional. Enfermeras participantes refirieron la inexistencia de diferencias en la atención entre PVVIH y otros pacientes, evidenciándose una incongruencia entre el discurso y el actuar en enfermería al ocupar mayores medidas de precaución al realizar procedimientos a PVVIH. Como fortalezas identificadas en la atención a PVVIH se encontró el no discriminar a pacientes, la capacidad de enfrentar distintos contextos de atención y la destreza procedimental, entre otras, mientras que los aspectos a mejorar en la atención se vincularon con la relación que se genera con los PVVIH y sus familiares. Como conclusión, las enfermeras no hacen mayores distinciones en la atención con PVVIH. Es importante que las profesionales reconozcan sus habilidades y aspectos a mejorar para seguir humanizando la atención a PVVIH, siendo agentes educadores y de cambio.

Pontos fortes identificados na atenção de portadores de HIV foram a não discriminação dos pacientes, a capacidade de enfrentar-se a distintos contextos na atenção, as habilidades de procedimentos, entre outras. Enquanto aos aspectos a melhorar na atenção se vincularam com a relação que se gera como os pacientes portadores de HIV e seus familiares Como conclusão os enfermeiros( não fazem maiores distinções na atenção de pacientes com HIV. É importante que os profissionais reconheçam suas habilidades e pontos para melhorar e assim continuar avançando na humanização da atenção dos portadores de HIV conseguindo ser agentes educadores e de mudança.

Abstract: Given the epidemiological context in Chile concerning the increased quantities of people with HIV, improving the care given to these patients becomes relevant. The objective of this research is to find about the perception of nurses concerning the care given to people living with HIV (PLHIV) in a tertiary health care hospital service, seeking to contribute to nursing improvements. In order to accomplish this task a qualitative research paradigm was used as a type of case study, collecting the information with a semi-structured interview, ending with a semiotic analysis of the discourse. It was pointed out that in the first sessions there is some fear generated in the attention to PLHIV, which gradually disappears with the increase of the professional's knowledge. Participating nurses referred to the lack of differences in care between PLHIV and other patients, evidencing an incongruence between the speech and the action by taking greater precautions when performing procedures for PLHIV. The strengths identified in the attention to PLHIV were the no discrimination to these patients, the ability to face different contexts of attention and the procedural skills, among others, while aspects to improvement in care were linked to the relationship that is generated with PLHIV and their families. In conclusion, nurses do not make noticeable distinctions in the care of PLVIH. It is important that professionals recognize their skills and the aspects that can be improved in order to continue humanizing the attention to PLHIV, acting as educators and agents of change.

Sublingual misoprostol is as effective as intravenous oxytocin to reduce intra-operative blood loss during cesarean delivery in women living at high altitude.

OBJECTIVE: To assess the effect of sublingual misoprostol compared to intravenous oxytocin for blood loss during cesarean delivery in women living at high altitude. STUDY DESIGN: In a randomized trial, conducted in Quito, Ecuador (2800 m above sea level), 100 women received either sublingual misoprostol (400 µg) or intravenous oxytocin (10 IU). RESULTS: Bleeding in the misoprostol was no different than in the oxytocin group. Shivering was reported in 66% of women in the misoprostol group. CONCLUSION: Sublingual misoprostol might be a valid alternative to oxytocin reduce intra-operative blood loss during cesarean section in women living at high altitude.

It is better to smile to women: gender modifies perception of honesty of smiling individuals across cultures.

Social perception studies have revealed that smiling individuals are perceived more favourably on many communion dimensions in comparison to nonsmiling individuals. Research on gender differences in smiling habits showed that women smile more than men. In our study, we investigated this phenomena further and hypothesised that women perceive smiling individuals as more honest than men. An experiment conducted in seven countries (China, Germany, Mexico, Norway, Poland, Republic of South Africa and USA) revealed that gender may influence the perception of honesty in smiling individuals. We compared ratings of honesty made by male and female participants who viewed photos of smiling and nonsmiling people. While men and women did not differ on ratings of honesty in nonsmiling individuals, women assessed smiling individuals as more honest than men did. We discuss these results from a social norms perspective.
