Abstract: The protective effects of Kangaroo mother care (KMC) on the neurodevelopment of preterm infants are well established, but we do not know whether the benefits persist beyond infancy. Our aim was to determine whether providing KMC in infancy affected brain volumes in young adulthood. Standardised cognitive, memory and motor skills tests were used to determine the brain volumes of 20‐year‐old adults who had formed part of a randomised controlled trial of KMC versus incubator care. Multivariate analysis of brain volumes was conducted according to KMC exposure. The study comprised 178 adults born preterm: 97 had received KMC and 81 were incubator care controls. Bivariate analysis showed larger volumes of total grey matter, basal nuclei and cerebellum in those who had received KMC, and the white matter was better organised. This means that the volumes of the main brain structures associated with intelligence, attention, memory and coordination were larger in the KMC group. Multivariate lineal regression analysis demonstrated the direct relationship between brain volumes and duration of KMC, after controlling for potential confounders. Our findings suggest that the neuroprotective effects of KMC for preterm infants persisted beyond childhood and improved their lifetime functionality and quality of life.

Abstract: Background. In 1978, kangaroo mother care (KMC) was proposed as a caring alternative for low birth weight (LBW) infants. We are reporting here early outcomes of a randomized, controlled trial comparing KMC to traditional care. Method. An open randomized, controlled trial was conducted in a large tertiary care hospital. All newborn infants ≤2000 g, surviving the neonatal period and being eligible for a minimal care unit, were included. A total of 1084 newborns ≤2000 g were followed, and 746 were randomized—382 to KMC and 364 to traditional care. KMC infants were discharged after randomization, regardless of weight or gestational age. Infants spent 24 hours per day in an upright position, in skin-to-skin contact, and attached to the mother's chest. After randomization, control infants remained at the minimal care unit until meeting usual discharge criteria. Both groups are being followed up to 12 months of corrected age 679 (90%) were available for evaluation when they reached term (40 to 41 weeks of postconceptional age). The present paper reports early outcomes (when reaching term) including mortality, infectious episodes, hospital stay after eligibility, and growth and feeding patterns. Results. Both study groups were similar regarding all baseline variables but weight at eligibility. The risk of dying was similar in both groups (relative risk = 0.59, 95% confidence interval 0.22–1.6). There were no differences in growth indices. Nosocomial infections were more frequent in control infants. Hospital stay after eligibility was shorter in KMC, primarily for infants ≤1800 g. Conclusions. These results show that KMC is a safe approach to the care of clinically stable LBW infants. Our findings provide the necessary scientific support to a method that is already incorporated in the care of LBW infants at many hospitals around the world and at different levels of care.

Abstract: Documenting the clinical course and forecast for a concurrent cohort of discharged preterm infants who received home oxygen in Bogota, Colombia. This was a prospective study of a concurrent cohort of 194 newborn infants having 34 weeks gestational age (GA) or less at birth who were born in 12 institutions and followed up for one year of corrected age to assess mortality, morbidity, growth and development. Oxygen dependency was mild in 49 infants (25.3 %) and moderate-severe in 145 of them (74.7 %). There were 3 deaths vital status was known in 169 infants at 40 weeks GA (87.1 %) and 103 (53%) at 1 year. Breast feeding at term was successful in 147 (75.8 %) infants. Growth indices at one year were appropriate (8,991 g weight, 73 cm height and 46.2 cm head circumference) 74.1 % of the cohort were still receiving home oxygen at 40 weeks and and 22.7 % at 3 months and oxygen was discontinued on average on postnatal day 109. 56.8 % of the cohort were readmitted to hospital at least once, 47% of them because of respiratory conditions. Only 71 % had ophthalmological screening and retinopathy of prematurity (ROP) was detected in 38 % of cases (4 severe cases: 3 laser surgery and 1 blind infant). Neuro-psychomotor and sensorial screening tests were only performed on 19 % of the infanys. More than 60 % of newborn infants discharged with home oxygen lacked structured follow-up. Oxygen-dependancy in infants is complex our data suggested that there is plenty of room for improvement in Bogotá in that respect.

Abstract: Describing preterm breast milk evolution and composition according to gestational age (GA) and postnatal age (PNA) in a cohort of mothers cared for in an ambulatory Kangaroo Mother Care Program (KMCP) in a developing country. A cohort involving 113 mothers who delivered 'healthy' preterms adequate for GA was assembled. Mothers received intensive breastfeeding support before discharge. S les of both fore- and hind milk were obtained at entry into KMCP and weekly thereafter, until term. Composition was described according to PNA and postconceptional age (PCA). Protein concentration varied inversely with both PCA and PNA. Fat concentration was consistently higher in hind milk than in fore milk s les of the same feed. Lactose increased steadily with PCA. Calcium hosphorus ratios were stable, close to 2:1 and content of both was similar in s les of different PCA and PNA. Minerals concentration could be inadequate for preterms. Protein concentration decreases steadily to mature milk levels by the third week of PNA, regardless of birth GA. Therefore, from the third week of PNA onwards, protein content could be insufficient to satisfy needs of preterms born at 32 weeks or less. Feeding hind milk could increase caloric density and fat intake to better meet preterms' nutritional needs.

Abstract: Randomized clinical trials have shown that Kangaroo Mother Care (KMC) can decrease morbidity and mortality due to low birthweight. Between 1994 and 2004, 44 teams in 25 developing countries were trained in KMC in Bogotá, Colombia however, not all the teams were successful in initiating their own programmes and, of those that started, not all replicated the validated model. To identify factors involved in unsuccessful KMC implementation and find solutions. A study was conducted in which 17 open-ended questionnaires were sent by e-mail to the coordinators of functioning KMC programmes in 15 countries, and 15 site visits were made to institutes that reported problems in starting programmes. The information was classified according to the perceived obstacle and the KMC model component involved. The early-discharge component (including ambulatory follow-up) was that found most difficult to implement. Resistance from health professionals, mothers and families was often related to local cultural practices. Active surveillance for and appropriate identification of obstacles usually indicated the appropriate solution. Some of the obstacles were common to many second-generation KMC programmes, making this information valuable for the implementation of programmes.

Abstract: Synovial microenvironment (SME) plays a vital role in the formation of synovial pannus and the induction of cartilage destruction in arthritis. In this work, a concept of the photocatalytic regulation of SME is proposed for arthritis treatment, and monodispersive hydrogen-doped titanium dioxide nanorods with a rutile single-crystal structure are developed by a full-solution method to achieve near infrared-photocatalytic generation of hydrogen molecules and simultaneous depletion of overexpressed lactic acid (LA) for realizing SME regulation in a collagen-induced mouse model of rheumatoid arthritis. Mechanistically, locally generated hydrogen molecules scavenge overexpressed reactive oxygen species to mediate the anti-inflammatory polarization of macrophages, while the simultaneous photocatalytic depletion of overexpressed LA inhibits the inflammatory/invasive phenotypes of synoviocytes and macrophages and ameliorates the abnormal proliferation of synoviocytes, thereby remarkably preventing the synovial pannus formation and cartilage destruction. The proposed catalysis-mediated SME regulation strategy will open a window to realize facile and efficient arthritis treatment.

Abstract: This study tested the hypothesis that Kangaroo Mother Care creates a climate in the family, which enhances infants' performance on the developmental quotient scale. The largest social security hospital in Colombia with a neonatal intensive care unit. At 12 months of corrected age, 194 families in the Kangaroo Mother Care group and 144 families in the Traditional Care group were available for analysis. Infants were kept 24 h/day in an upright position, in skin-to-skin contact until it was no longer tolerated by the infants. Babies in the Traditional Care were kept in incubators on the Minimal Care Unit until they satisfied the usual discharge criteria. The Home Observation for Measurement of the Environment (HOME), Father Involvement and Developmental Quotient (Griffiths) scores. 1) Kangaroo mothers created a more stimulating context and a better caregiving environment than mothers in the Traditional Care group 2) this environment was positively correlated to father involvement and 3) the family environment of male infants was most improved by Kangaroo Mother Care. Kangaroo Mother Care has a positive impact on home environment. The results also suggest, first, that both parents should be involved as direct caregivers in the Kangaroo Mother Care procedure and secondly, that this intervention should be directed more specifically at infants who are more at risk at birth. The Kangaroo Mother Care intervention could be an excellent means to ensure parents' mature involvement in the future of their children.

Abstract: Breast-milk fortifiers recommended for premature infants are seldom available in developing countries. We describe the characteristics of growth in preterm infants under ambulatory Kangaroo Mother Care (KMC) who eventually required supplemental formula because of failure to thrive with exclusive breast feeding. We evaluated the relationship between growth indices at term, nutritional status of the infant at birth, and feeding pattern. Prospective cohort study conducted in the Neonatal Unit at Clínica San Pedro Claver and the KMC program, an ambulatory clinic from the Clínica del Niño tertiary care clinics in Bogotá, Colombia. Included were 115 mothers and their 129 healthy, preterm infants. One hundred twenty-six (98.4%) infants were available for evaluation at term. Infant weights were monitored daily until they achieved 15 g/kg per day for 2 days and then weekly until term. Formula was offered only to infants who did not gain 15 g per kg per day for 3 consecutive days. Sixty (47.6%) infants gained weight adequately with exclusive breast feeding. In 14 of those who needed supplements, adequate weight gain was achieved before reaching term and supplements could be stopped. The more immature infants required supplementation more frequently. With or without supplementation, infants with lower weight for gestational age at birth were less likely to achieve adequate weight by term. Growth indices at term in premature infants were close to those expected for term infants born in Bogotá (between percentile 10 to percentile 25). Decision on formula supplementation of breast milk should be made not only based on birth weight or gestational age but on a careful monitoring of weight gain while the mother is receiving continuous support to enhance and maintain successful breast-feeding. Small-for-date premature infants thrive less well than other infants even with supplementation.

Abstract: Since Kangaroo Mother Care (KMC) was developed in Colombia in the 1970s, two trends in clinical application emerged. In low income settings, the original KMC model is implemented. This consists of continuous (24 h/day, 7 days/week) and prolonged mother arent-infant skin-to-skin contact early discharge with the infant in the kangaroo position (ideally) exclusive breastfeeding and, adequate follow-up. In affluent settings, intermittent KMC with sessions of one or a few hours skin-to-skin contact for a limited period is common. As a result of the increasing evidence of the benefits of KMC for both infants and families in all intensive care settings, KMC in a high-tech environment was chosen as the topic for the first European Conference on KMC, and the clinical implementation of the KMC model in all types of settings was discussed at the 7th International Workshop on KMC. Kangaroo Mother Care protocols in high-tech Neonatal Intensive Care Units (NICU) should specify criteria for initiation, kangaroo position, transfer to/from KMC, transport in kangaroo position, kangaroo nutrition, parents' role, modification of the NICU environment, performance of care in KMC, and KMC in case of infant instability. Implementation of the original KMC method, with continuous skin-to-skin contact whenever possible, is recommended for application in high-tech environments, although scientific evaluation should continue.

Abstract: Background. Based on the general bonding hypothesis, it is suggested that kangaroo mother care (KMC) creates a climate in the family whereby parents become prone to sensitive caregiving. The general hypothesis is that skin-to-skin contact in the KMC group will build up a positive perception in the mothers and a state of readiness to detect and respond to infant's cues. Method. The randomized controlled trial was conducted on a set of 488 infants weighing & g, with 246 in the KMC group and 242 in the traditional care (TC) group. The design allows precise observation of the timing and duration of mother–infant contact, and takes into account the infant's health status at birth and the socioeconomic status of the parents. Bonding Assessment. Two series of outcomes are assessed as manifestations of a mother's attachment behavior. The first is the mother's feelings and perceptions of her premature birth experience, including her sense of competence, feelings of worry and stress, and perception of social support. The second outcome is derived from observations of the mother and child's responsivity to each other during breastfeeding at 41 weeks of gestational age. Interventions. KMC has three components. The first is the kangaroo position. Once the premature infant has adapted to extrauterine life and is able to breastfeed, he is positioned on the mother's chest, in a upright position, with direct skin-to-skin contact. The second component is kangaroo nutrition. Although breastfeeding is the prime source of nutrition, infants also may receive preterm formula whenever necessary and vitamin supplements. The third component is the clinical control infants are monitored on a regular basis, daily until they are gaining at least 20 g per day. Afterward, weekly clinic visits are scheduled until term, which constitutes the ambulatory minimal neonatal care. In the TC group, infants are kept in incubators until they are able to self-regulate their temperature and are thriving (ie, have an appropriate weight gain). Infants are discharged according to current hospital practice, usually not before their weight is ∼1700 g. Afterward, as with the KMC group, weekly clinic visits are scheduled until term. Results. We observed a change in the mothers' perception of her child, attributable to the skin-to-skin contact in the kangaroo-carrying position. This effect is related to a subjective “bonding effect” that may be understood readily by the empowering nature of the KMC intervention. Moreover, in stressful situations when the infant has to remain in the hospital longer, mothers practicing KMC feel more competent than do mothers in the TC group. This is what we call a resilience effect. In these stressful situations we also found a negative effect on the feelings of received support of mothers practicing KMC. We interpret this as an isolation effect. To thwart this deleterious effect, we would suggest adding social support as an integral component of KMC. The observations of the mothers' sensitive behavior did not show a definite bonding effect, but rather a resilience effect. This is attributable to the KMC intervention mothers practicing KMC were more responsive to an at-risk infant whose development has been threatened by a longer hospital stay. Otherwise, we observed that the mothers (in both the KMC group and the TC group) had behavioral patterns that were adapted to the child's at-risk health status and to the precarious condition of some premature infants requiring intensive care. We conclude that the infant's health status may be a more prominent factor in explaining a mother's more sensitive behavior, which overshadows the kangaroo-carrying effect. Conclusion. These results suggest that KMC should be promoted actively and that mothers should be encouraged to use it as soon as possible during the intensive care period up to the 40 weeks of gestational age. Thus, KMC should be viewed as a means of humanizing the process of giving birth in a context of prematurity. This finding confirms the conclusions of the 1996 Trieste workshop suggesting that KMC should be promoted both in hospitals and after early discharge.

Abstract: Given that prematurity has deleterious effects on brain networking development beyond childhood, the study explored whether an early intervention such as Kangaroo Mother Care (KMC) in very preterm preemies could have influenced brain motor function up to adolescence. Transcranial magnetic stimulation (TMS) was applied over the primary motor cortex (M1) of 39 adolescents born very prematurely ( 37 weeks' gestational age, >2500 g) to assess the functional integrity of motor circuits in each hemisphere (motor planning) and between hemispheres (callosal function). All TMS outcomes were similar between KMC and term adolescents, with typical values as in healthy adults, and better than in Controls. KMC adolescents presented faster conduction times revealing more efficient M1 cell synchronization (p < 0.05) and interhemispheric transfer time (p < 0.0001), more frequent inhibitory processes with a better control between hemispheres (p < 0.0001). The enhanced synchronization, conduction times and connectivity of cerebral motor pathways in the KMC group suggests that the Kangaroo Mother Care positively influenced the premature brain networks and synaptic efficacy up to adolescence.

Abstract: We compare the educational effects of two medical protocols that mitigate long-term consequences of prematurity or low birth weight. The two protocols are Traditional Care (TC), which uses incubators, and Kangaroo Mother Care (KMC) which replaces incubators for 24-hour skin-to-skin contact between newborns and caregivers. We concentrate on educational outcomes addressing contradictory results in previous contributions. We use a randomized controlled trial implemented in 1993 that randomly assigned children to either TC or KMC. OLS results suggest that KMC children spent more time in preschool, had fewer temporary school absences, and showed lower math test scores. Both groups observed similar effects on high-school graduation and language test scores. We correct for attrition, small s le, and multiple outcomes. Effects on preschool attendance and school absenteeism are robust, particularly for more vulnerable infants (birth weight ≤ 1,800 g). The other effects lose statistical significance due to multiple outcome testing or attrition corrections.

Abstract: The hallmark of Kangaroo Mother Care (KMC) is the kangaroo position: the infant is cared for skin-to-skin vertically between the mother's breasts and below her clothes, 24 h/day, with father/substitute(s) participating as KMC providers. Intermittent KMC (for short periods once or a few times per day, for a variable number of days) is commonly employed in high-tech neonatal intensive care units. These two modalities should be regarded as a progressive adaptation of the mother-infant dyad, ideally towards continuous KMC, starting gradually and progressively with intermittent KMC. The other components in KMC are exclusive breastfeeding (ideally) and early discharge in kangaroo position with strict follow-up. Current evidence allows the following general statements about KMC in affluent and low-income settings: KMC enhances bonding and attachment reduces maternal postpartum depression symptoms enhances infant physiologic stability and reduces pain, increases parental sensitivity to infant cues contributes to the establishment and longer duration of breastfeeding and has positive effects on infant development and infant arent interaction. Therefore, intrapartum and postnatal care in all types of settings should adhere to a paradigm of nonseparation of infants and their mothers/families. Preterm/low-birth-weight infants should be regarded as extero-gestational foetuses needing skin-to-skin contact to promote maturation. Kangaroo Mother Care should begin as soon as possible after birth, be applied as continuous skin-to-skin contact to the extent that this is possible and appropriate and continue for as long as appropriate.

Abstract: Mild maternal hypothyroidism during pregnancy can adversely affect infant development. We studied thyrotropin (TSH) levels in mothers of premature and low-birth-weight infants in Colombia, where iodized salt supplements the diet to correct iodine deficiency. The additional impact of salt restriction in mothers with hypertensive disorders was examined. Blood was spotted on filter paper from 404 mothers and their infants. Using radioimmunoassay (RIA), TSH was measured in the mothers, and TSH and thyroxine in their infants at three postpartum times. Initially, mothers had high TSH levels (i.e., TSH > 10 mU/L in half the mothers at the first assessment). Fourteen days later, only 9.3%, and at calculated term 7.5% were greater than 10 mU/L. Maternal TSH levels correlated with infant birth weight and gestational age (r = 0.47, and r = 0.49, p < 0.01). Initial TSH values were higher in salt restricted (20.1 +/- 2 mU/L, n = 76) versus control mothers (14.6 +/- 0.85, n = 328, p < 0.01), dropping dramatically in both groups 14 days later (to 3.4 +/- 0.7 mU/L vs. 2.8 +/- 0.4 mU/L) and at calculated term (2.8 +/- 0.4 mU/L vs. 2.3 +/- 0.6 mU/L). Increased maternal TSH levels during pregnancy in an iodine-deficient area may be aggravated by salt restriction. Monitoring TSH and supplementing iodine or thyroxine are recommended in pregnancy, especially if dietary salt restriction is prescribed.

Abstract: The aim of this retrospective study was to evaluate the clinical outcome of fixed tooth- and implant-supported protheses manufactured in porcelain veneered cobalt-chromium (CoCr) or titanium with a follow-up period of 5-9 years. This study included 63 patients with a total of 86 fixed dental protheses (FDPs) (53 implant-supported and 33 tooth-supported). In total, 67 were short-span FDPs (3-5 units) and 19 were long-span FDPs (6-12 units). The FDPs were evaluated using a modified version of the California Dental Association (CDA). The binary regression analysis indicated that neither CoCr nor titanium had a statistically significant effect on the odds of success or survival of either tooth- or implant-supported FDPs. However, the success of FDPs was negatively affected by greater FDP length and general tooth wear. The survival of FDPs was negatively affected by increased FDP longevity. This study found no statistically significant effect on the odds of success and survival outcomes for any combination of tooth-supported, implant-supported, porcelain-veneered CoCr, or porcelain-veneered titanium FDPs. As the number of FDPs was limited, the results should be interpreted with caution. This study shows that the choice between CoCr porcelain and titanium porcelain in fixed protheses did not have a statistically significant effect on the outcome.

Abstract: To assess the effectiveness and safety of Kangaroo Mother Care (KMC) for infants of low birth weight. An open, randomized, controlled trial of a Colombian social security referral hospital was conducted. A total of 1084 consecutive infants who were born at ≤2000 g were followed, and 746 newborns were randomized when eligible for minimal care, with 382 to KMC and 364 to “traditional” care. Information on vital status was available for 693 infants (93%) at 12 months of corrected age. KMC consisted of skin-to-skin contact on the mother's chest 24 hours/day, nearly exclusive breastfeeding, and early discharge, with close ambulatory monitoring. Control infants remained in incubators until the usual discharge criteria were met. Both groups were followed at term and at 3, 6, 9, and 12 months of corrected age. The main outcomes measured were morbidity, mortality, growth, development, breastfeeding, hospital stay, and sequelae. Baseline variables were evenly distributed, except for weight at recruitment (KMC: 1678 g control participants: 1713 g). The risk for death was lower among infants who were given KMC, although the difference was not significant (KMC: 11 [3.1%] of 339 control participants: 19 [5.5%] of 324 relative risk: 0.57 95% confidence interval: 0.17–1.18). The growth index of head circumference was statistically significantly greater in the group given KMC, but the developmental indices of the 2 groups were similar. Infants who weighed ≤1500 g at birth and were given KMC spent less time in the hospital than those who were given standard care. The number of infections was similar in the 2 groups, but the severity was less among infants who received KMC. More of these infants were breastfed until 3 months of corrected age. These results support earlier findings of the beneficial effects of KMC on mortality and growth. Use of this technique would humanize the practice of neonatology, promote breastfeeding, and shorten the neonatal hospital stay without compromising survival, growth, or development.

Abstract: i Objective: /i To assess whether complete kangaroo mother care (KMC), a skin-to-skin contact intervention, would affect longitudinal/developmental patterns of hormonal change. i Method: /i An open randomized controlled trial was conducted in a large tertiary care hospital, comparing KMC and traditional care for newborn infants weighing less than 2,001 g. Eighty-seven healthy preterm ( weeks gestational age) infants from this study provided three blood-spot s les on filter paper: at randomization (postnatal age 1–5 days), 2 weeks later, and at calculated term (41 weeks gestational age). They met a number of additional inclusion criteria including discharge from the hospital within the first postnatal week. The levels of 17α-hydroxy-progesterone (17-OHP), thyroxine-stimulating hormone (TSH) and thyroxine (T sub /sub ) were assessed by radioimmunoassay. Birth weight ( ,800 or ≧1,800 g) and prenatal maternal corticosteroid treatment were taken into account in the analysis. i Interventions: /i Complete KMC includes early discharge, positioning the infant on the parent’s chest in an upright position, 24 h/day in skin-to-skin contact, and breast-feeding. In the traditional care group, infants were discharged according to routine hospital practice. i Results: /i Levels of 17-OHP and TSH decreased significantly from eligibility to calculated term while T sub /sub levels did not change significantly over time. Most importantly, overall, treatment (KMC) did not interact with the pattern of physiological change. i Conclusions: /i Maturation of the pituitary-thyroid axis and adrenal function is apparently not compromised by KMC, at least in healthy preterm infants.
