Review
Several studies have shown that accelerated growth in the postnatal period is critical for the development of chronic diseases. The term catch-up has been used for the accelerated growth of children who have suffered some sort of restriction of nutrition or oxygen supply. However, accelerated growth has been observed among children who have an appropriate birth weight for their gestational age (AGA) and with no apparent morbidity. Therefore, this systematic review was carried out on the associated factors of accelerated growth, or catch-up, using the Medline/Pubmed database. Only cohort studies written in Portuguese, English or Spanish, with children between zero and 12 years old who presented accelerated growth or catch-up as the outcome were included. Out of the 2,155 articles found, 9 were selected. There is no uniformity in the operational definition of accelerated growth, or in the concept of catch-up. According to this review, accelerated growth is associated with primiparity, maternal smoking during pregnancy, lower birth weight, and early weaning. The main limitations in the available literature are the high number of follow-up losses and the lack of control for confounding factors. The determinants of accelerated growth still need to be studied further, especially among AGA children.

There is a wealth of evidence for a lifespan penalty when environmental conditions influence an individual's growth trajectory, such that growth rate is accelerated to attain a target size within a limited time period. Given this empirically demonstrated relationship between accelerated growth and lifespan, and the links between lifespan and telomere dynamics, increased telomere loss could underpin this growth-lifespan trade. We experimentally modified the growth trajectory of nestling zebra finches (), inducing a group of nestlings to accelerate their growth between 7 and 15 days of age, the main phase of body growth. We then sequentially measured their telomere length in red blood cells at various time points from 7 days to full adulthood (120 days). Accelerated growth between 7 and 15 days was not associated with a detectable increase in telomere shortening during this period compared with controls. However, only in the treatment group induced to show growth acceleration was the rate of growth during the experimental period positively related to the amount of telomere shortening between 15 and 120 days. Our findings provide evidence of a long-term influence of growth rate on later-life telomere shortening, but only when individuals have accelerated growth in response to environmental circumstances.

Review
BACKGROUND
Whilst prevention of growth faltering has both short- and long-term health benefits, whether too fast or accelerated infant growth adversely affects later health outcomes is controversial and a major focus of research.
SUMMARY
Many observational studies suggest that rapid weight gain in infancy (upward centile crossing) increases the long-term risk of obesity and non-communicable disease. This association has been seen in infants from low- and high-income countries, in infants born preterm or at term, and those born with normal or low birth weight for gestation. Experimental (randomized) studies in both breast- and formula-fed infants support a causal link between early growth acceleration and infant nutrition and later risk of obesity. These observations suggest that strategies to optimize the pattern of infant growth could make a major contribution to stemming the current global epidemic of non-communicable disease. Key Messages: The optimal pattern of infant weight gain is likely to differ in different populations. The benefits of rapid infant weight gain for later neurodevelopment favors the promotion of rapid growth in infants born preterm. However, growth acceleration in healthy infants born at term (either normal or low birth weight for gestation) is likely to have adverse effects for long-term health.

Previous research has demonstrated accelerated head and body growth during infancy in children with autism spectrum disorders. No study has yet examined head growth in children who lose their autism spectrum disorder diagnoses. Head circumference, length, and weight growth during infancy for 24 children who maintained their diagnoses were compared with 15 children who lost their diagnoses, and to 37 typically developing controls. Results showed that head circumference and weight growth were significantly greater in both autism spectrum disorder groups compared with controls, with no significant differences between autism spectrum disorder groups. However, when length and weight were controlled for, accelerated head growth remained significant in the children who lost their diagnoses. Findings suggest that children who lose their autism spectrum disorder diagnoses and children who maintain their diagnoses show similar head circumference, length, and weight growth trajectories during infancy, although subtle differences in body growth between groups may exist.

In this paper, a simple numerical procedure is presented to monitor the growth of Streptococcus sanguinis over time in the absence and presence of propolis, a natural antimicrobial. In particular, it is shown that the real-time decomposition of growth curves obtained through optical density measurements into growth rate and acceleration can be a powerful tool to precisely assess a large range of key parameters (i.e., lag time [], starting growth rate [γ], initial acceleration of the growth [], maximum growth rate [γ], maximum acceleration [], and deceleration [] of the growth and the total number of cells at the beginning of the saturation phase []) that can be readily used to fully describe growth over time. Consequently, the procedure presented provides precise data of the time course of the different growth phases and features, which is expected to be relevant, for instance, to thoroughly evaluate the effect of new antimicrobial agents. It further provides insight into predictive microbiology, likely having important implications for assumptions adopted in mathematical models to predict the progress of bacterial growth. The new and simple numerical procedure presented in this paper to analyze bacterial growth will possibly allow the identification of true differences in efficacy among antimicrobial drugs for their applications in human health, food security, and the environment, among others. It further provides insight into predictive microbiology, likely helping in the development of proper mathematical models to predict the course of bacterial growth under diverse circumstances.

The stimulation of photosynthesis is a strategy for achieving sustainable plant production. Red light is useful for plant growth because it is absorbed by chlorophyll pigments, which initiate natural photosynthetic processes. Ultraviolet (UV)-to-red wavelength-converting materials are promising candidates for eco-friendly plant cultures that do not require electric power. In this study, transparent films equipped with a UV-to-red wavelength-converting luminophore, the Eu complex, were prepared on commercially available plastic films for plant growth experiments. The present Eu-based films absorb UV light and exhibit strong red luminescence under sunlight. Eu-painted films provide significant growth acceleration with size increment and biomass production for vegetal crops and trees in a northern region. The plants cultured with Eu-painted films had a 1.2-fold height and 1.4-fold total body biomass than those cultures without the Eu luminophores. The present film can promote the plant production in fields of agriculture and forestry.

Since some antifreeze proteins and glycoproteins (AF(G)Ps) cannot directly bind to all ice crystal planes, they change ice crystal morphology by minimizing the area of the crystal planes to which they cannot bind until crystal growth is halted. Previous studies found that growth along the -axis (perpendicular to the basal plane, the crystal plane to which these AF(G)Ps cannot bind) is accelerated by some AF(G)Ps, while growth of other planes is inhibited. The effects of this growth acceleration on crystal morphology and on the thermal hysteresis activity are unknown to date. Understanding these effects will elucidate the mechanism of ice growth inhibition by AF(G)Ps. Using cold stages and an infrared laser, ice growth velocities and crystal morphologies in AF(G)P solutions were measured. Three types of effects on growth velocity were found: concentration-dependent acceleration, concentration-independent acceleration, and concentration-dependent deceleration. Quantitative crystal morphology measurements in AF(G)P solutions demonstrated that the adsorption rate of the proteins to ice plays a major role in determining the morphology of the bipyramidal crystal. These results demonstrate that faster adsorption rates generate bipyramidal crystals with diminished basal surfaces at higher temperatures compared to slower adsorption rates. The acceleration of growth along the -axis generates crystals with smaller basal surfaces at higher temperatures leading to increased growth inhibition of the entire crystal.

Regulation of final organ size is a complex developmental process that involves the integration of systemic and organ-specific processes. Previously, we have shown that in developing Drosophila, perturbing the growth of one imaginal disc - the parts of a holometabolous larva that become the external adult organs - retards growth of other discs and delays development, resulting in tight inter-organ growth coordination and the generation of a correctly proportioned adult. Whether different parts of the same imaginal disc similarly coordinate their growth to generate a functioning adult organ is, however, unclear. In this study, we use the wing imaginal disc in Drosophila to study and identify mechanisms of intra-organ growth coordination. We generate larvae in which the two compartments of the wing imaginal disc have ostensibly different growth rates (wild-type or growth-perturbed). We find that there is tightly coordinated growth between the wild-type and growth-perturbed compartments, where growth of the wild-type compartment is retarded to match that of the growth-perturbed compartment. Crucially, this coordination is disrupted by application of exogenous 20-hydroxyecdysone (20E), which accelerates growth of the wild-type compartment. We further elucidate the role of 20E signaling in growth coordination by showing that in wild-type discs, compartment-autonomous up-regulation of 20E signaling accelerates compartment growth and disrupts coordination. Interestingly, growth acceleration through exogenous application of 20E is inhibited with suppression of the Insulin/Insulin-like Growth Factor Signaling (IIS) pathway. This suggests that an active IIS pathway is necessary for ecdysone to accelerate compartment growth. Collectively, our data indicate that discs utilize systemic mechanisms, specifically ecdysone signaling, to coordinate intra-organ growth.
