ABSTRACT
Huanglongbing (HLB) is a citrus disease of worldwide importance, associated with the presence of Candidatus Liberibacter asiaticus (Las) and vectored by the psyllid Diaphorina citri in Asia and the Americas. To properly manage HLB, removal of inoculum sources and control of the psyllid are undertaken. We evaluated the percentage of the psyllid population with Las, sampled from yellow sticky traps over a three-year period and its relationship with insect population, regions, season of the year, and HLB management in citrus areas in the southwestern, central, and northern regions of São Paulo (SP) and southwestern region of Minas Gerais states, Brazil. In each reading, up to 50 psyllids per region were collected and detection of Las in individual psyllids were made by quantitative polymerase chain reaction. The percentage of psyllids with Las-an average of 65.3%-was constant throughout the year in the southwestern region of SP state, while showing an increase from spring to autumn when sampled from central to northern regions. The proportion of psyllids carrying Las from each region and year period were compared by a proportion test and spectral density analysis. The proportion of psyllids carrying Las evaluated in the same region in different seasons presented statistical differences in central (Araraquara) and southwestern (Santa Cruz do Rio Pardo) regions in 2015, with higher values in the first semester (summer and autumn) than in the second semester (winter and spring). Orchards with poor HLB management had higher incidence of psyllids with Las. Spectral density analysis indicated that good management areas had 50% less relevant peaks of psyllids with Las than in areas with poor HLB management practices. The relationship between the percentage of psyllids carrying Las and the number of captured psyllids in the region in a given time denotes the most critical intake time for HLB spread in citrus orchards. The reduction in the population of psyllids carrying Las is a direct benefit from the use of good management practices.
ABSTRACT
Background: Studies that establish the indicators of clinical status deterioration of Ineffective airway clearance remain scarce. Prognostic studies provide data for nurses identify clinical indicators that suggest a higher chance of early development of a nursing diagnosis. Objective: To identify the prognostic indicators of short-term survival of ineffective airway clearance (IAC) in children with acute respiratory infection (ARI). Design: A prospective open cohort study. Methods: This study was with a group of 136 children with acute respiratory infection who were followed for a minimum of six and a maximum of ten consecutive days. Children who had not completed six days of monitoring or who were carriers of diseases that would alter the specific symptoms of respiratory infection were excluded. The survival rate of ineffective airway clearance was calculated using Nelson-Aalen's method. A Cox regression model was used to analyze the influence of clinical indicators on survival time of this diagnosis. Results: The diagnosis survival rate was extremely low (only 0.4% on the 5th day of follow-up). The greatest reduction in survival rate was observed in the first 48 h (survival rate = 2.5%). Four defining characteristics associated with a worse prognosis of IAC among children with ARI: ineffective cough (RR = 5.86; 95% CI: 3.53-9.72), absence of cough (RR = 2.92; 95% CI: 1.68-5.08), adventitious breath sounds (RR = 2.47; 95% CI: 2.01-3.03), and diminished breath sounds (RR = 1.23; 95% CI: 1.05-1.45). Conclusion: Four clinical indicators showed a strong relationship with an increased risk of worsening clinical status associated with this nursing diagnosis. Impact statement: Clinical deterioration related to ineffective airway clearance among children with acute respiratory infection is fast and requires particular attention from nurses.

Resumo: Entendendo a monogamia como dispositivo contingencial, analisa-se sua capacidade de influenciar os processos de constituição da identidade e as formas de identificação dos sujeitos. A partir das elaborações de Heinz Lichtenstein sobre as origens da identidade humana, incluímos a monogamia, ou alguns traços presentes neste arranjo, na unidade mãe-bebê, supondo que o estatuto hegemônico da monogamia revela algo de sua ligação com a situação antropológica fundamental descrita por Laplanche. Assim, traços do arranjo monogâmico seriam transmitidos à criança em seu estado de "órgão" da mãe e, enquanto pontos constitutivos da identidade, seriam compulsivamente repetidos com o objetivo de manter a coesão desta identidade.
Abstract: With the understanding that monogamy is a contingent device, the paper intends to analyze its ability to influence the processes of identity constitution of the subjects. From Heinz Lichtenstein's elaborations on the origins of human identity, we include monogamy, or some traits present in this arrangement, in the mother-infant unit, supposing that the hegemonic status of monogamy reveals some of its connection with the fundamental anthropological situation described by Laplanche. Thus, traces of the monogamous arrangement would be transmitted to the child in its "organ" state and would be compulsively repeated as constitutive points of identity, in order to maintain the cohesion of this identity.

PURPOSE: To establish prognostic indicators of survival for impaired gas exchange (IGE) (00030). METHODS: Secondary analysis of data from an open prospective cohort developed with a group of 136 children with acute respiratory infection (ARI). FINDINGS: On Day 1, IGE (00030) was present in 42.6% of the sample. New cases arose until the last day of evaluation. With regards to defining characteristics, only hypoxemia and abnormal skin color were associated with a higher risk of developing diagnosis. CONCLUSIONS: Children with ARI who exhibit hypoxemia and abnormal skin color had a worse prognosis for IGE (00030). IMPLICATIONS FOR NURSE PRACTICE: Nurses can use the research findings as a predictive marker of the evolution of the patient's health status.

The identification of clinical indicators with good predictive ability allows the nurse to minimize the existing variability in clinical situations presented by the patient and to accurately identify the nursing diagnosis, which represents the true clinical condition. The purpose of this study was to analyze the accuracy of NANDA-I clinical indicators of the nursing diagnosis ineffective airway clearance (IAC) in children with acute respiratory infection. This was a prospective cohort study conducted with a group of 136 children and followed for a period of time ranging from 6 to 10 consecutive days. For data analysis, the measures of accuracy were calculated for clinical indicators, which presented statistical significance in a generalized estimated equation model. IAC was present in 91.9% of children in the first assessment. Adventitious breath sounds presented the best measure of accuracy. Ineffective cough presented a high value of sensitivity. Changes in respiratory rate, wide-eyed, diminished breath sounds, and difficulty vocalizing presented high positive predictive values. In conclusion, adventitious breath sounds showed the best predictive ability to diagnose IAC in children with respiratory acute infection.

The aim of this study was to identify the defining characteristics that allow clinical differentiation of the nursing diagnoses, ineffective breathing pattern (IBP), ineffective airway clearance (IAC), and impaired gas exchange (IGE). A secondary analysis with a cohort design was developed from 1128 records obtained during the hospital stay of 136 children with acute respiratory infection. Groups of defining characteristics with greater differentiation capacity were identified by multiple correspondence analyses. The results showed that the defining characteristics that better differentiate the studied diagnoses are agitation, irritability and diaphoresis for IGE; dyspnea, use of accessory muscles to breathe, orthopnea, and abnormal breathing pattern for IBP and excessive sputum, absence of cough, difficulty verbalizing, nasal flaring, and adventitious breath sounds for IAC. Twelve defining characteristics that can assist clinicians to differentiate the three main respiratory nursing diagnoses among children with acute respiratory infection were identified in this study.

AIMS AND OBJECTIVES: To identify prognostic clinical indicators of short-term survival for ineffective breathing pattern in children with acute respiratory infection. BACKGROUND: Despite the studies of survival for nursing diagnosis, there is not enough evidence about the clinical indicators that are associated with a worse prognosis for ineffective breathing pattern. DESIGN: A prospective cohort study. METHODS: One hundred and thirty-six children were followed up for a minimum of six and a maximum of 10 consecutive days. The survival rate for ineffective breathing pattern was calculated using Nelson-Aalen's method. An extended Cox model was adjusted to identify the main prognostic clinical indicators for this nursing diagnosis. RESULTS: Over half of the sample had an ineffective breathing pattern at the first evaluation. The occurrence of new cases was observed until the ninth day of monitoring, and the survival rate after this day was low. According to the Cox model, the main clinical indicators of a poor prognosis were an abnormal breathing pattern, the use of accessory muscles, dyspnoea and increase in the anterior-posterior chest diameter. CONCLUSIONS: Children with acute respiratory infection who present with an abnormal breathing pattern, the use of accessory muscles to breathe, dyspnoea and increased anterior-posterior diameter have a poor prognosis for an ineffective breathing pattern. RELEVANCE TO CLINICAL PRACTICE: Survival analyses of nursing diagnoses allow the identification of clinical indicators that can be used in clinical practice as prognostic markers. The identification of indicators associated with a poor clinical prognosis allows nurses to intervene early and to maximise the possibility of a good outcome.

MÉTODO: Estudio observacional, descriptivo transversal desarrollado entre abril y septiembre de 2013 en un hospital ubicado en el nordeste de Brasil con una muestra de 205 niños. Los diagnósticos fueron establecidos por enfermeros expertos formados en esta materia. Se calcularon las medidas de sensibilidad, especificidad, valor de predicción positivo y negativo, razón de verosimilitud positiva y negativa y odds ratio diagnóstica para las características definitorias identificadas. RESULTADOS: Un 28,8% de los niños evaluados presentaron «deterioro del intercambio de gases». La disnea, la respiración anormal, la taquicardia y la hipoxemia presentaron las frecuencias más altas. La hipoxemia como característica clínica ha presentado valores altos de sensibilidad y especificidad. Un 5,9% de los niños evaluados presentaron «deterioro de la ventilación espontánea» y sus características definitorias más frecuentes fueron la disnea, el aumento de la frecuencia cardíaca y la disminución de la SaO2. El uso creciente de los músculos accesorios para respirar presentó las mejores medidas de validez para este diagnóstico. CONCLUSIÓN: La hipoxemia y el uso creciente de los músculos accesorios presentaron las mejores medidas de la validez respectivamente para «deterioro del intercambio de gases» y «deterioro de la ventilación espontánea». Es necesario contemplar estas características para una adecuada definición y uso de los diagnósticos en la práctica clínica

AIMS AND OBJECTIVES: The purpose of this study was to assess the prevalence of ineffective breathing pattern and the accuracy of its defining characteristics, among children and adolescents with congenital heart disease. BACKGROUND: The NANDA International nursing diagnosis, ineffective breathing pattern, has been noted to have high prevalence in different clinical contexts and age groups. Despite that, nurses continue to report difficulties in confirming this diagnosis. The lack of data regarding the sensitivity, specificity and predictive values of the defining characteristics contribute to decreased certainty in diagnosing ineffective breathing pattern. DESIGN: A diagnostic accuracy study. METHODS: This study of diagnostic accuracy was conducted with 61 children and adolescents with congenital heart disease. Two nurses were trained by the primary investigator on use of defining characteristics in the diagnostic process for ineffective breathing pattern. RESULTS: Ineffective breathing pattern was present in 26·2% of the children and adolescents sampled. When analysing the defining characteristics, alterations in depth of breathing, showed high values of sensitivity and specificity. In addition, orthopnoea, tachypnoea and use of accessory muscles to breathe, showed high values of specificity; dyspnoea showed high values of sensitivity. Finally, assumption of three-point position, bradypnoea and increased anterior-posterior diameter were not found to be statistically significant for this sample population. CONCLUSION: Five defining characteristics of ineffective breathing pattern presented measures of accuracy with statistically significant values in children with congenital heart disease. RELEVANCE TO CLINICAL PRACTICE: The findings can help nurses during the diagnostic process, as they identify which defining characteristics can be used to confirm or rule out the probability of occurrence of the diagnosis.

PURPOSE: To analyze the accuracy of the defining characteristics of impaired gas exchange (IGE). METHODS: Cross-sectional study carried out in 93 cardiac postoperative adult patients. The 19 NANDA-I defining characteristics related to IGE were evaluated. FINDINGS: Ten defining characteristics were found in the sample. The best accuracy values, including specificity, diagnostic odds ratio, and likelihood ratios, inter alia, were found to decreased carbon dioxide, abnormal arterial blood gases, abnormal arterial pH, and abnormal breathing. CONCLUSION: Some clinical indicators predict the presence/absence of IGE more accurately than others. IMPLICATIONS FOR NURSING PRACTICE: Knowledge of the accuracy of defining characteristics allows an early identification of particular nursing diagnoses, which can prevent complications.

Objetivou-se validar clinicamente uma árvore de decisão (AD) desenvolvida para diferenciação de dois diagnósticos de enfermagem respiratórios: Padrão respiratório ineficaz (PRI) e Desobstrução ineficaz de vias aéreas (DIVA). Esta árvore de decisão foi desenvolvida em um estudo prévio com 249 crianças como Infecção respiratória aguda. Dentre as geradas, a AD desenvolvida com o algoritmo Classification and Regression Trees foi escolhida para ser validada clinicamente por apresentar melhor poder de predição global (86,4%). Estudo do tipo metodológico desenvolvido a partir de registros de bancos de dados que serviram de subsídio para construção de duas dissertações de mestrado. Calculou-se uma amostra de 222 registros, sendo estes de 111 crianças com Infecção respiratória aguda e 111 com Asma. Foram estruturados três grupos de diagnosticadores: grupo de Padrão de Referência, grupo controle e grupo caso. O grupo caso teve acesso à Árvore de Decisão como ferramenta para auxílio na inferência diagnóstica. As inferências dos grupos de comparação (caso e controle) foram analisadas tomando como parâmetro balizador a inferência realizada pelo grupo Padrão de referência. As inferências dos diagnosticadores foram tabuladas em uma planilha do software Excel e os dados analisados no IBM SPSS versão 21.0 for Windows e no pacote estatístico R. Dos 222 registros analisados, 55,9% eram do sexo masculino, possuíam como principal antecedente familiar a Asma (57,2%), seguido de Tuberculose (17,6%). DIVA foi diagnosticado em 80,6% e PRI em 68,5% dos registros avaliados pelo grupo Padrão de Referência. Crianças mais jovens foram diagnosticadas mais vezes com ambos os diagnósticos em estudo. Frequência à creche e maior tempo de frequência foram mais prevalentes nas crianças sem os diagnósticos. As características definidoras com associação estatística com DIVA foram: Dispneia (84,68%, p<0,001), Ruídos adventícios respiratórios (84,23%, p<0,001), Tosse ineficaz (72,07%, p<0,001), Ortopneia (70,72%, p<0,001). Já para PRI, encontrou-se associação com Dispneia (85,13%, p<0,001), Alteração na profundidade respiratória (69,81%, p<0,001), Ortopneia (69,81%, p<0,001), Taquipneia (64,86%, p<0,001) e Uso da musculatura acessória para respirar (66,66%, p<0,001). Os diagnosticistas que utilizaram a AD obtiveram índices de concordância com o grupo Padrão de Referência superiores aos dos que não utilizaram a ferramenta de apoio. Foram necessárias maiores intervenções no grupo de diagnosticistas sem a AD para que a igualdade das inferências fosse alcançada. Este dado aponta para capacidade da ferramenta de tornar as inferências mais homogêneas. Melhores taxas de sensibilidade, especificidade, odd ratio diagnóstica, razões de verossimilhança positiva e negativa foram observados para as inferências do grupo com a AD. Dado os resultados apresentados, conclui-se que a ferramenta validada neste estudo contribuiu para inferências de maior qualidade, aumentando assim a acurácia das determinações diagnósticas. Pela alta taxa de sensibilidade e elevadas taxas de falso-positivo, a AD validada possui caraterísticas típicas de ferramentas de triagem diagnóstica.(AU)
