The Effect of Fathers' Kangaroo Care Experience of Preterm Babies on Paternal Attachment / 중환자간호학회지

PURPOSE: This study was intended to standardize the Kangaroo care protocol for fathers, and to determine the effect of fathers' Kangaroo care experience on paternal attachment.METHODS: The data was collected from February to April, 2013. The study subjects were 34 fathers (17 experimental group subjects, 17 control group subjects) of premature babies, bornatatertiaryhospitalinSeoul, who agreed to participate. The standardized Kangaroo care protocol, which consisted of at least three 60-minutes sessions during the hospitalization period in a neonatal intensive care unit, was carried out with the experimental group. The data was analyzed by a χ2-test and Mann-Whitney U test.RESULTS: The results were as follows: 1) There were no between-group differences in the general characteristics of babies and their fathers. 2) The Kangaroo care fathers showed higher scores of paternal attachment than the control group (Z=-3.657, p=0.008).CONCLUSION: Fathers who attended the Kangaroo care sessions showed stronger paternal attachment than those who did not. Therefore, use of a Kangaroo care program for fathers of premature babies at neonatal intensive care units is recommended.

National Survey of Kangaroo Care Practice, Barriers, Knowledge, and Belief / 임상간호연구

PURPOSE: A National survey was conducted to assess neonatal intensive care nurses' practice, barriers, knowledge, and belief regarding Kangaroo Care (KC). METHODS: A descriptive survey was conducted. Kangaroo care questionares were sent to nurses in all hospitals in Korea whose were identified as providing neonatal intensive care services(N=263). Descriptive statistics were used to summarized the data. RESULTS: Among 67 neonatal care units, 61.1% adapted KC in their practice. About 60% of nurses in the KC providing hospital actually practiced KC. Major barrier of practicing KC were infant safety concerns, as well as work load of nurses. Respondants who had practiced KC were more knowledgable and were more positive in their belief regarding KC. CONCLUSION: The findings suggest that in order to overcome barriers of practicing KC, educational programs are recommended designed for nurses. In addition, development of KC practice guideline is necessary to facilicate successful and safe KC.

Infection with Toxoplasma gondii in a red kangaroo (Macropus rufus) and a Patagonian mara (Dolichotis patagonum) in captivity / Infecção por Toxoplasma gondii em um canguru vermelho (Macropus rufus) e em uma mara (Dolichotis patagonum) em cativeiro

Abstract Toxoplasmosis is an infectious, zoonotic and parasitic disease, caused by Toxoplasma gondii. In this manucript, two cases of infection with T. gondii in captive animals from a zoological park in the central region of Chile are described. One case was a red kangaroo (Macropus rufus), which is highly susceptible to the infection, and the other was a Patagonian mara (Dolichotis patagonum), a rodent in which there is no previous report of the infection. Both animals had myocarditis, with the presence of intralesional tachizoites and cysts suggestive of infection with T. gondii. This infection was confirmed by immunohistochemistry in both animals. The origin of the infection is unknown, but it is likely that free ranging domestic felines were associated with the dissemination of the parasites. This highlights the importance of controlling the domestic animal populations in zoological parks. To the best of our knowledge, this is the first time that T. gondii infection is described in a Patagonian mara, adding a new host for this infectious agent.

Resumo Toxoplasmose é uma doença parasitária infecciosa e zoonótica causada por Toxoplasma gondii. São descritos dois animais com toxoplasmose, mantidos em cativeiro, em um zoológico na região central do Chile. Um destes foi um canguru vermelho (Macropus rufus), o qual é altamente suscetível à infecção; o outro foi uma mara (Dolichotis patagonum), um roedor sem relato prévio de infecção por T. gondii. Ambos os animais tinham miocardite associada a organismos protozoários intralesionais, sugestivos de infecção por Toxoplasma gondii. Esta infecção foi confirmada pela imuno-histoquímica, nos dois animais. A origem da infecção é desconhecida, mas é provável que felinos domésticos errantes estejam associados com a disseminação do protozoário. Isso destaca a importância do controle populacional de animais domésticos em zoológicos. Até onde se sabe, esta é a primeira vez que a infecção por T. gondii é descrita em uma mara, adicionando um novo hospedeiro para este agente infeccioso.

Analysis of Studies on High-Risk Infants and Quality Assessment of Intervention Studies

PURPOSE: It is critical that evidence from research is applied to everyday nursing practice to improve the quality of care and health outcomes. Aims of this study were to review high-risk infant related studies published in major nursing and non-nursing journals in Korea and to assess the quality of intervention studies. METHODS: Through the Korean literature search engine of RISS.KR the authors identified 132 studies, and two researchers evaluated each of these studies using the analysis criteria. The quality of intervention studies was assessed using the van Tulder Scale. RESULTS: Among the studies, 40.2% were either thesis or dissertation and 86.4% were quantitative studies. Convenience sampling was the most commonly used sampling method. All experimental studies were quasi-experiment except one pre-experiment study. Sensory stimulation and kangaroo care were the most common interventions for high-risk infants. Over half of the intervention studies were assessed to be "low risk of bias" but both randomization and blinding processes were not adequately satisfied in most of the studies. CONCLUSION: Findings of this study suggest that high-risk infants are more likely to be recruited for experimental studies but types of interventions were very limited. To provide evidence-based care for high-risk infants, rigorously conducted experimental studies should be encouraged.

Knowledge and Beliefs about Kangaroo Care among Nursing Students

PURPOSE: This study was conducted to investigate nursing students' knowledge and beliefs about Kangaroo care (KC). METHODS: A cross-sectional descriptive design was used. Undergraduate students enrolled in departments of nursing (n=322) from three universities in D city participated. Knowledge and beliefs about KC were measured using the Kangaroo Care Questionnaire (KCQ). RESULTS: The overall level of nursing students' knowledge about KC was very low with a mean score of 6.9 out of 17. The mean score for nursing students' beliefs about KC was 87.4 out of 100, indicating relatively positive beliefs. The students who had both education and exposure to KC had higher scores for knowledge and more positive beliefs about KC compared to students with no experience or exposure to KC. There was a positive correlation between knowledge and beliefs about KC (r=.371, p<.001). CONCLUSION: The results suggest that there is a need to develop educational programs for nursing students in order to increase their knowledge and develop positive beliefs about KC.

Characteristics of Animal Shoulder Models for Rotator Cuff Experiments

Animal shoulder models are important in the investigation of the natural history of various pathologic conditions and for evaluation of the effectiveness of different treatments and biomaterials. The characteristics of animal shoulder models that may be used for rotator cuff related experiments are different with regard to the anatomy, behavioral pattern, advantages and disadvantages in application to each other. The lower primates and all the non-primate species, except the tree kangaroo, were neither functional overhead nor had a true rotator cuff. Utilizing more advanced primates, or perhaps even the tree kangaroo would be ideal and the most relevant to man as they possess a true rotator cuff. However, ethical concerns, costs, and many limitations in obtaining primates generally preclude the use of these animals for such research. Finally we should consider the differences in comparative anatomy and behavioral pattern of each animal model during performance or interpretation of rotator cuff experiments.

Efficacy and Safety of Kangaroo Mother Care in Preterm Infants in Korea / 대한주산의학회잡지

PURPOSE: This study aimed to identify the safety of Kangaroo Mother Care (KMC) and to analyze its medical and psychological effects. METHODS: Forty five preterm infants, admitted to Gangnam Severance Hospital NICU from October 2012 to September 2013, were recruited. KMC was performed for 1 hour daily until the discharge by either mother or father. The medical effects in KMC group were compared with historical control group. Psychological effects in KMC group were made a comparison with the non-KMC group. RESULTS: The mean gestational age was 31.3+/-3.5 weeks, and the mean birth weight was 1,080+/-250 g. KMC was started at the mean age of 18.3+/-8.4 days. No event of hypothermia, bradycardia, desaturation, or hypotension occurred. There was no event of death or sepsis. Four patients (9%) had apnea but recovered after the tactile stimulation. Duration of the hospitalization in KMC group was significantly shorter than control group (P=0.041). Spielberger's anxiety scale decreased from 49.7 to 48.5. Muller's maternal attachment inventory increased from 98.4 to 99.5. Reduction of the self-happiness score improved from 5% to 70%. The score for Spielberger's anxiety scale tended to be lower in the KMC group than in the control group without statistically significant. Muller's maternal attachment inventory score was significantly higher in the KMC group. CONCLUSION: KMC is a safe method to Korean preterm infants. Due to reduction of hospitalization and beneficial psychological effect, we believe that offering KMC to more preterm infants as a supplement therapy will be useful.

Integrative Review of Nursing Intervention Studies on Mother-Infant Interactions

PURPOSE: The purpose of this study was to describe the components and content of nursing intervention studies on mother-infant interactions and to present strategies for future studies. METHODS: Four electronic databases in the Korean language were searched to identify studies done between January 1998 and December 2011. The search yielded 145 articles. From these articles, 19 studies met the inclusion criteria. RESULTS: Mother-infant interactions in these studies were found to include verbal and non-verbal communication basic for optimal growth and development of the child. Six kinds of interventions for mother-infant interactions were identified as follows: sensory stimulation, education program, whole body massage, kangaroo care, visiting support, and music therapy. CONCLUSION: Further studies with well designed clinical trials need to be done in the area of child nursing to provide evidence based data for the development of strategies to promote positive mother-infant interactions.

Toxoplasmosis sistémica en un canguro rojo (Macropus rufus) cautivo / Systemic toxoplamosis in a captive red kangaroo (Macropus rufus)

Los objetivos del estudio fueron presentar y documentar los hallazgos histopatológicos de toxoplasmosis sistémica en un canguro rojo (Macropus rufus) mantenido en cautiverio donde se describen los hallazgos macro y microscópicos encontrados y los análisis adicionales realizados. En el laboratorio de histopatología animal (Universidad de los Llanos) se recibieron muestras de tejidos fijados en formol tamponado, al 10% que procedían de un ejemplar macho de Macropus rufus, de ocho años de edad y 50 kg de peso corporal. Las muestras se procesaron mediante métodos rutinarios para microscopía óptica. Los cortes histológicos de 3-4 mm de grosor se colorearon con Hematoxilina-Eosina (H&E) y se realizó en algunos cortes la tinción de Ácido Periódico Schiff (PAS), PCR e IHQ. Al análisis histopatológico se encontró una toxoplasmosis sistémica asociada a quistes de protozoarios con inmunoreactividad positiva para T. gondii. La detección de T gondii en tejidos en formalina fue hecha usando dos ensayos de PCR que señalaban segmentos de ADN de diferentes secuencias repetitivas encontradas en T gondii y la IHQ confirmo lo hallado por PCR. Histopatológicamente se diagnosticó infección crónica por protozoarios eucoccideos de la familia Sarcocystidae. El diagnóstico etiológico fue de toxoplasmosis.

The objetives of this study were to present and document the hystopathologycal findings of systemic toxoplamosis in a captive red kangaroo (Macropus rufus) which described macro and microscopic findings of the hystopathological analysis. In the laboratory of animal histopathology (Universidad de los Llanos) formalin fixed tissue specimens were received, from a captive male Macropus rufus, who was eight years old and weighed 50 kg. The samples were processed by usual methods for optical microscopy. The histological sections of 3-4 mm thick were colored with Hematoxilin-Eosin (H&E) and then some samples stained with Periodic Acid Schiff (PAS), and processed by PCR and IHQ. Once the histopathological analysis was performed systemic toxoplasmosis was associated to protozoa cysts immunoreactives to T. gondii. The molecular detection of T. gondii in formalin fixed tissues was made using two PCR tests and confirmated by IHQ. Histopathologically a chronic infection by an eucoccideo protozoa from the Sarcocystidae family was diagnosed. The etiologic diagnosis was toxoplasmosis.

Lens proteome map and -crystallin profile of the catfish Rita rita.

Crystallins are a diverse group of proteins that constitute nearly 90% of the total soluble proteins of the vertebrate eye lens and these tightly packed crystallins are responsible for transparency of the lens. These proteins have been studied in different model and non-model species for understanding the modifications they undergo with ageing that lead to cataract, a disease of protein aggregation. In the present investigation, we studied the lens crystallin profile of the tropical freshwater catfish Rita rita. Profiles of lens crystallins were analyzed and crystallin proteome maps of Rita rita were generated for the first time. A-crystallins, member of the -crystallin family, which are molecular chaperons and play crucial role in maintaining lens transparency were identified by 1-and 2-D immunoblot analysis with anti-A-crystallin antibody. Two protein bands of 19-20 kDa were identified as A-crystallins on 1-D immunoblots and these bands separated into 10 discrete spots on 2-D immunoblot. However, anti-B-crystallin and antiphospho-B-crystallin antibodies were not able to detect any immunoreactive bands on 1- and 2-D immunoblots, indicating B-crystallin was either absent or present in extremely low concentration in Rita rita lens. Thus, Rita rita -crystallins are more like that of the catfish Clarias batrachus and the mammal kangaroo in its A- and B-crystallin content (contain low amount from 5-9% of aB-crystallin) and unlike the dogfish, zebrafish, human, bovine and mouse -crystallins (contain higher amount of B-crystallin from 25% in mouse and bovine to 85% in dogfish). Results of the present study can be the baseline information for stimulating further investigation on Rita rita lens crystallins for comparative lens proteomics. Comparing and contrasting the -crystallins of the dogfish and Rita rita may provide valuable information on the functional attributes of A- and B-isoforms, as they are at the two extremes in terms of A-and B-crystallin content.

Perception of Nurses and Physicians in Neonatal Intensive Care Units on Kangaroo Care

PURPOSE: To identify the perception and practices of kangaroo care in nurses and doctors working in neonatal intensive care units (NICU) in Korea. METHODS: One hundred forty-nine nurses and nineteen doctors working in the NICU from six university hospitals completed a survey questionnaire. RESULTS: Most agreed that Kangaroo care promoted attachment and parental confidence as well as physical health of the infant. However, nurses and doctors showed a negative perception in providing kangaroo care for premature infants under 1,000 grams or within several hours after birth. Major barriers for kangaroo care were worrying about extubation and safety problems of premature infants. Married or senior nurses showed a more positive perception than others. Also nurses who worked in hospitals where kangaroo care was provided had a lower barrier perception than other nurses. CONCLUSION: Nurses and doctors working in NICU worried about adverse effects of kangaroo care even though they perceived positive effects. Standard education programs and manuals should be developed before dissemination of kangaroo care in Korea.

The Effects of Kangaroo Care on Maternal Self-esteem and Premature Infants' Physiological Stability / 여성건강간호학회지

PURPOSE: This paper identified the effects of kangaroo care (KC) on maternal self-esteem and the growth and physiological stability of premature infants hospitalized in the neonatal intensive care unit. METHODS: The experiment was conducted with an experimental group of 17 infants, and a control group of 17 infants selected by convenience sampling. KC was given to the infants one time a day for 30 minutes after feeding for two weeks. Their weight was measured every morning, and their physiological stability was measured in terms of their body temperature, respiratory rate, heart rate, oxygen saturation, and stability of the cardio-respiratory system in premature infants (SCRIP) score, as physiological responses at every 10 minutes during the intervention. Maternal self-esteem was assessed by a maternal self-report inventory. RESULTS: The experimental group showed significant increase in the self-esteem of mothers. Also, KC was effective on physiological stabilization of preterm infants. CONCLUSION: This study suggests that KC can be provided in clinical settings more widely in Korea as one of the nursing interventions aimed at promoting maternal self-esteem as well as infants' physiological stabilization.

Gross anatomy of the heart in the western grey kangaroo (Macropus fuliginosus) / Anatomía macroscópica del corazón en el canguro gris occidental (Macropus fuliginosus)

The aim of this study was provide a description of the macroscopic heart anatomy of the kangaroo Macropus fuliginosus. The terms of the Nomina Anatomica Veterinaria were employed. Heart did not have interventricular sulcus. Auricles were located in both faces of the heart. Right ventricle had slight septomarginal trabecula that extended between papilar muscles and the parietal wall. Right ventricle parietal wall had plenty of trabecula carneae. Septal wall was smooth and had three papilar muscles. Papilar muscles of left ventricle were two and they were located over parietal wall. Septal walls and parietal of left ventricle were full of trabecula carneae that surrounded papilar muscles. Two vessels derived from the aorta, right and left sinus coronary arteries and a septal artery. Septal artery gave irrigation to interventricular septum and derived from left sinus of the aorta and their lumen had a higher diameter than the left coronary artery. Coronary arteries had intra myocardic route.

El objetivo de este estudio fue proporcionar una descripción de la anatomía macroscópica de corazón el canguro Macropus fuliginosus. Fueron empleados los términos de la Nomina Anatómica Veterinaria. El corazón no tuvo surco interventricular. Las aurículas se encontraban en ambas caras del corazón. El ventrículo derecho presentó una trabécula septomarginal delgada que se extendía entre los músculos de la pared papilar y parietal. La pared parietal del ventrículo derecho presentó un montón de trabéculas carnosas. La pared septal era lisa y tenía tres músculos papilares. Los músculos papilares del ventrículo izquierdo fueron dos y se encontraron en la pared parietal. Las paredes septal y parietal del ventrículo izquierdo estaban llenas de trabéculas carnosas que rodeaban los músculos papilares. Dos vasos procedentes desde la aorta, arterias del seno coronario derecho e izquierdo, y la arteria septal.

Las arterias coronarias presentaron un trayecto intramiocardico.

Physiological Effects of Kangaroo Care(skin-to-skin care) in Small Preterm Infants and Their Parents

PURPOSE: Kangaroo care is the practice of holding a small premaure infant, naked except for a diaper and hat, against a parent's chest. The purpose of this study is to determine the safety and feasibility of kangaroo care in a NICU as defined by physiological variables. MEHTODS: Ten stable, spontaneously breathing preterm infants, weighing less than 2,000gm were included in this 60-min. Kangaroo care (kc) study. Physiological variables, including heart and respiratory rates, blood pressure, skin and core temperature, pulse oximetry oxygen saturation and maternal serum prolactin were measured before, during and after kc. RESULTS: Kc did not significantly affect any of these infants' physiological variables before and during kc. Maternal core temperature rose significantly during kc (36.7+/-0.4 degree (C) vs 37.0+/-0.2 degree (C), P< 0.05). After kc, the mean prolactin level (233.3+/-240.6ng/ml) of mothers was higher than the preceding day(81.9+/-94.2ng/ml) and before kc (71.2+/-96.3ng/ml) (P<0.05). CONCLUSION: For stables preterm infants weighing less than 2,000gm, 60min of kc is safe and well tolerated. The beneficial effects of kc such as stability of the preterm infants receiving kc and increase of maternal prolactin after kc suggest the need to incorporate it into standards of care.

The Effects of Kangaroo Care on Anxiety and Confidence and Gratification of Mothering Role in Mothers of Low Birth Weight Infants / 아동간호학회지

This study was performed to investigate the effect of kangaroo care on anxiety and confidence and gratification of mothering role in mothers of low birth weight infants. The subjects were 30 mothers of low birth weight infants, sixteen for the kangaroo care group and fourteen for the control group, whose infants hospitalized in two neonatal intensive care unit at two university-affiliated hospital. The kangaroo care was applied 9 times during the twenty six days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a low birth weight infant wearing a diaper and a hat is placed on its mother's chest. The questionnaire, state anxiety was completed before beginning the first intervention. The questionnaire, state anxiety and confidence and gratification of mothering role were completed at 2 weeks after discharge. The data were analyzed by a SPSS program. The results were as follows : 1. There were no significant differences in the state anxiety between the kangaroo care and the control group before beginning the first intervention. The state anxiety was significantly lower in kangaroo care group than in control group. 2.The confidence of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 3.The gratification of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 4. In mothers of low birth weight infants, the state anxiety was negatively correlated to the confidence of mothering role and the gratification of mothering role at 2 weeks after discharge. And the confidence of mothering role in mothers of low birth weight infants was positively correlated to the gratification of mothering role at 2 weeks after discharge. These results suggest that kangaroo care is an effective nursing intervention for mothers of low birth weight infants in reducing the state anxiety, improving the confidence and gratification of mothering role.

The Effects of Kangaroo Care on Body Weight, Physiologic Responses and Behavioral States in Premature Infants / 간호학회지

This study was performed to investigate the effect of kangaroo care on body weight, physiological responses and behavioral states in premature infants. The subjects were 32 premature infants, fifteen for the kangaroo care group and seventeen for the control group, who hospitalized in a neonatal intensive care unit at a university-affiliated hospital. The kangaroo care was applied 8 times during the twenty five days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a premature infant wearing a diaper and a hat is placed on its mother's chest. As for the measures, body weight was measured everyday. The levels of epinephrine, norepinephrine and 17-OHCS were measured twice, before beginning the first intervention and after finishing the last intervention. While each session of the care is undergoing, such physiological responses were measured periodically as heart rate, respiration rate, oxygen saturation, core temperature and skin temperature. The results were as follows : 1. The weight gain was significantly greater in the kangaroo care group than that in the control group during the period of performing the kangaroo care. 2. No significant difference was revealed between the two groups in heart rate, respiration rate, oxygen saturation and core temperature. The kangaroo care group also showed significant increases in the skin temperature. 3. The differences in the levels of epinephrine, norepinephrine and 17-OHCS were not significant between the kangaroo care and the control groups. The level of norepinephrine in the two groups was significantly increased over time. 4. Sleep pattern changed significantly in the kangaroo group from a very restless sleep to a very quiet sleep. These results suggest that kangaroo care is an effective nursing intervention for premature infants in gaining weight, achieving stable physiological responses and facilitating a quiet sleep.
