Review
The adverse outcomes on the offspring from maternal diabetes in pregnancy are substantially documented. In this paper, we report main knowledge on impacts of maternal diabetes on early and long-term health of the offspring, with specific comments on maternal obesity. The main adverse outcome on progenies from pregnancy complicated with maternal diabetes appears to be macrosomia, as it is commonly known that intrauterine exposure to hyperglycemia increases the risk and programs the offspring to develop diabetes and/or obesity at adulthood. This "fetal programming", due to intrauterine diabetic milieu, is termed as "metabolic memory". In gestational diabetes as well as in macrosomia, the complications include metabolic abnormalities, degraded antioxidant status, disrupted immune system and potential metabolic syndrome in adult offspring. Furthermore, there is evidence that maternal obesity may also increase the risk of obesity and diabetes in offspring. However, women with GDM possibly exhibit greater macrosomia than obese women. Obesity and diabetes in pregnancy have independent and additive effects on obstetric complications, and both require proper management. Management of gestational diabetes mellitus and maternal obesity is essential for maternal and offspring's good health. Increasing physical activity, preventing gestational weight gain, and having some qualitative nutritional habits may be beneficial during both the pregnancy and offspring's future life.

Review
The aim of the present review was to explore the effect of parental misperceptions of their offspring's weight status during childhood and early adolescence on weight control strategies and children's eating behavior. Literature searching was limited to the PubMed database and to the English language from January 2000 to August 2022. Eligible studies had clearly associated parental misperception of offspring's weight with child eating habits or weight management and eating strategies in childhood to early adolescence. Sixteen studies (14 cross-sectional, 1 longitudinal and 1 with cross-sectional and longitudinal analyses) were included in the analysis. Weight loss attempts and child's eating behavior were the main outcomes. Sixteen studies found significant associations. Parental misperceptions of their offspring's weight status do influence their child's weight and eating behavior, especially in overweight children. Parents tend to follow potentially harmful methods when they overestimate their children's weight (food restriction) and when they underestimate their children's weight (pressure to eat). However, additional longitudinal studies are needed to better understand the impact of parental weight status perception on health behaviors and children's weight gain over time. The potential need for preventive intervention studies is warranted.

The internal (i.e., interoceptive) sensations that characterise hunger vary between people, and this may also be the case for thirst, although it has not been so well explored. There are probably both heritable and learning-based causes for this interoceptive variability. Consequently, it would seem plausible that parents and their offspring would have more similar patterns of hunger and thirst than pairs of strangers. We tested this idea, in addition to exploring its potential moderating variables, by studying the similarity of self-reported hunger and thirst sensations in 170 students and their primary caregivers from childhood. Both students and caregivers completed the same online-survey, covering hunger and thirst sensations, beliefs about the causes of hunger and thirst, the Three Factor Eating Questionnaire (revised) and demographic data. We find evidence of robust student-caregiver similarity in interoceptive hunger and thirst sensations (medium effect sizes), with these being moderated by caregiver beliefs about the homeostatic nature of each state (medium effect sizes). This suggests a potential role for caregivers in the development of their offspring's interoceptive cues for hunger and for thirst. In addition, thirst, like hunger, appears to be multidimensional, and varies between people. The implications of these findings are discussed.

Review
BACKGROUND
Some persons conceived with donor gametes react negatively when they found their birth via donor conception. They request access to information about and seek to communicate with the donor. However, some countries mandate donor anonymity. Other countries allow donor-conceived persons to access donor information, but they can only use this access if their parents have disclosed donor conception to them. We investigated a thorny issue of donor conception: whether donor conception should be shifted from an anonymous basis to a non-anonymous basis.
METHODS
We review the issues and concerns regarding donor conception. We then consider the impact of direct-to-consumer genetic testing on donor conception, as well as the influence of donor conception on offspring's identity and the potential of different types of donors. To discuss the future policy of donor conception, the policies on the anonymity of gamete donors were investigated using publicly-available documents in 15 countries.
RESULTS
The aim of mandating donor anonymity is to protect the privacy of the donor and intended parents. However, the diffusion of direct-to-consumer genetic testing may make it impossible to maintain anonymity. Birth via donor conception shapes the offspring's identity, and the donor may further influence the development of offspring's identity through communications. It remains important to disclose donor conception to donor-conceived offspring and to provide them with donor information. However, that information might be insufficient for some donor-conceived persons. Here are benefits to having open-identity donors and known donors. Such donors can make an agreement with the parents regarding future communication with the offspring, although both sides should respect privacy. Subsequent counseling for all parties involved can result in better tripartite communication agreements.
CONCLUSIONS
In sum, ethical and practical issues that complicate donor anonymity are driving a shift to non-anonymous donor conception, in which all parties come to a communication agreement. To pave the way for such a donor conception system, transitional measures can be put into place. For countries that already adopted non-anonymous donor conception, ensuring the communication agreements is important to protect the rights of parents, donor, and offspring.

Conditions during gestation, such as maternal smoking, may affect offspring's bone structure. This could increase the offspring's risk of bone fractures during childhood. In this study, we aimed to assess the association between prenatal exposure to maternal smoking and childhood bone fracture risk. We used a register-based birth cohort that included all children born in Finland between January 1987 and September 1990. After exclusions, the final study population consisted of 220,699 persons. Using a unique national identification number, we linked the cohort data to the fracture diagnosis in specialty care and covariate data using the Medical Birth Register (MBR), Statistics Finland and Care Register for Health Care (CRHC). The fractures were analyzed in three groups: all fractures, non-high-energy fractures, and high-energy fractures. The analyses were adjusted for sex, parity, child's year of birth, mother's age at childbirth, mother's and father's educational level, and mother's fracture status. We tested the association in three age groups: <1 year, 1-<5 years, and 5-<15 years using Cox and (recurrent fractures) Poisson regression. A total of 18,857 (8.5%) persons had at least one bone fracture diagnosis before the age of 15 years. In the age group 5-<15 years, maternal smoking during pregnancy was associated with higher fracture risk in all of the studied fracture groups: hazard ratio (HR) = 1.12 (95% confidence interval [CI] 1.06-1.17) in all fractures, 1.13 (95% CI 1.07-1.19) in non-high-energy, and 1.15 (95% CI 1.00-1.32) in high-energy fractures. There were no significant associations in other age groups in any of the fracture groups. No statistically significant association between maternal smoking during pregnancy and offspring's risk of recurrent fractures was found. In conclusion, 5- to 15-year-olds whose mothers have smoked during pregnancy have an increased risk of bone fractures treated in specialty care. © 2023 The Authors.

Because phenotypic plasticity can operate both within and between generations, phenotypic outcomes are often shaped by a complex history of environmental signals. For example, parental and embryonic experiences with predation risk can both independently and interactively influence prey offspring traits early in their life. Parental and embryonic risk experiences can also independently shape offspring phenotypes throughout an offspring's ontogeny, but the persistence of their interactive effects throughout offspring ontogeny is unknown. We examined the effects of parental and embryonic experiences with predation risk on the response of 1-year-old prey (the carnivorous snail, ) offspring to current predation risk. We found that parental and embryonic risk experiences had largely independent effects on offspring performance and that these effects were context dependent. Parental experience with risk had strong impacts on multiple offspring traits in the presence of current risk that generally improved offspring performance under risk, but embryonic risk experience had relatively weaker effects and only operated in the absence of current risk to reduce offspring growth. These results illustrate that past environmental experiences can dynamically shape organism phenotypes across ontogeny and that attention to these effects is key to a better understanding of predator/prey dynamics in natural systems.

BACKGROUND
From the very beginning of life, biological events in the intrauterine environment influence the developing child, its growth, maturation and adaptation. The aim of this study was to assess the impact of maternal vitamin D and adiponectin status on offspring growth, general and bone health.
METHODS
162 healthy pregnant women were included in the study, with their vitaminD and adiponectin levels measured in the 32 nd week of pregnancy. Body weight and bone mineral density measurements of their offspring were performed at birth and at the age of three, six, nine and twelve months. Information on children's infectious, allergic and chronic disease was collected from their medical records.
RESULTS
Vitamin D insufficiency/deficiency was present in 44% of pregnant women. There was no significant association between maternal vitamin D during pregnancy and offspring body weight at birth or later, as well as between maternal vitamin D and newborn bone mineral density. Additionally, there was no significant association between maternal vitamin D and infectious, allergic or other chronic diseases in offspring. A negative correlation between maternal adiponectin and offspring's body weight at birth was observed (r = - 0.37, p = 0.002), while association with bone mineral density in newborns was not significant.
CONCLUSION
Despite the significant prevalence of vitamin D insufficiency among pregnant women, it did not influence growth or health of their offspring in this study. Maternal adiponectin levels showed an inverse relationship with birth weight of the infants, which may highlight the important link between maternal health and the offspring's growth.

The current study investigated the effects of the maternal Zn source in conjunction with their offspring’s dietary Zn supplementation on the growth performance, antioxidant status, Zn concentration, and immune function of the offspring. It also explored whether there is an interaction between maternal Zn and their offspring’s dietary Zn. One-day-old Lingnan Yellow-feathered broilers (n = 800) were completely randomized (n = 4) between two maternal dietary supplemental Zn sources [maternal Zn−Gly (oZn) vs. maternal ZnSO4 (iZn)] × two offspring dietary supplemental Zn doses [Zn-unsupplemented control diet (CON), the control diet + 80 mg of Zn/kg of diet as ZnSO4]. oZn increased progeny ADG and decreased offspring mortality across all periods, especially during the late periods (p < 0.05). The offspring diet supplemented with Zn significantly improved ADG and decreased offspring mortality over the whole period compared with the CON group (p < 0.05). There were significant interactions between the maternal Zn source and offspring dietary Zn with regards to progeny mortality during the late phase and across all phases as a whole (p < 0.05). Compared with the iZn group, the oZn treatment significantly increased progeny liver and serum Zn concentrations; antioxidant capacity in the liver, muscle, and serum; and the IgM concentration in serum; while also decreasing progeny serum IL-1 and TNF-α cytokine secretions (p < 0.05). Similar results were observed when the offspring diet was supplemented with Zn compared with the CON group; moreover, adding Zn to the offspring diet alleviated progeny stress by decreasing corticosterone levels in the serum when compared to the CON group (p < 0.05). In conclusion, maternal Zn−Gly supplementation increased progeny performance and decreased progeny mortality and stress by increasing progeny Zn concentration, antioxidant capacity, and immune function compared with the same Zn levels from ZnSO4. Simultaneously, Zn supplementation in the progeny’s diet is necessary for the growth of broilers.

Review
Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder with both reproductive and metabolic abnormalities affecting women of reproductive age. While the exact origin of PCOS is unknown, observations from clinical and animal studies suggest that maternal hyperandrogenism may be a contributing factor. Because women with PCOS manifest hyperandrogenism during pregnancy, changes in the gestational endocrine milieu may play a role in the vertical transmission of this syndrome. This review discusses the potential developmental origins of PCOS, the impact of maternal PCOS on the offspring's health and contributions of the postnatal environment, capitalizing on findings from animal models that exhibit a PCOS-like phenotype. In addition, this review highlights the scarcity of data at early gestational stages in humans and the importance of animal experimentation to better understand the cellular and molecular mechanisms involved in the programming of adult diseases, therefore, helping identify therapeutic targets for preventive and treatment strategies.

The Effects of Prenatal Supplementation with β-Hydroxy-β-Methylbutyrate and/or Alpha-Ketoglutaric Acid on the Development and Maturation of Mink Intestines Are Dependent on the Number of Pregnancies and the Sex of the Offspring.
Prenatal and postnatal supplementation with β-hydroxy-β-methylbutyrate (HMB) and alpha-ketoglutaric acid (AKG) affects the development and maturation of offspring. Both substances have the potential to stimulate cell metabolism via different routes. However, parity affects development and may alter the effects of dietary supplementation. This study aimed to evaluate the effect of gestational supplementation with HMB and/or AKG to primiparous and multiparous minks on the structure and maturation of the offspring's small intestine. Primiparous and multiparous American minks (), of the standard dark brown type, were supplemented daily with HMB (0.02 g/kg b.w.) and/or AKG (0.4 g/kg b.w.) during gestation ( = 7 for each treatment). Supplementation stopped when the minks gave birth. Intestine samples were collected from 8-month-old male and female offspring during autopsy and histology and histomorphometry analysis was conducted (LAEC approval no 64/2015). Gestational supplementation had a long-term effect, improving the structure of the offspring's intestine toward facilitating absorption and passage of intestinal contents. AKG supplementation affected intestinal absorption (enterocytes, villi and absorptive surface), and HMB affected intestinal peristalsis and secretion (crypts and Goblet cells). These effects were strongly dependent on parity and offspring gender. Present findings have important nutritional implications and should be considered in feeding practices and supplementation plans in animal reproduction.
