© 2020 The Authors The assessment of behavioral outcomes is a central component of neuroscientific research, which has required continuous technological innovations to produce more detailed and reliable findings. In this article, we provide an in-depth review on the progress and future implications for three model organisms (mouse, rat, and Drosophila) essential to our current understanding of behavior. By compiling a comprehensive catalog of popular assays, we are able to compare the diversity of tasks and usage of these animal models in behavioral research. This compilation also allows for the evaluation of existing state-of-the-art methods and experimental applications, including optogenetics, machine learning, and high-throughput behavioral assays. We go on to discuss novel apparatuses and inter-species analyses for centrophobism, feeding behavior, aggression and mating paradigms, with the goal of providing a unique view on comparative behavioral research. The challenges and recent advances are evaluated in terms of their translational value, ethical procedures, and trustworthiness for behavioral research.

© 2019 John Wiley  &  Sons Ltd Background: Human milk (HM) transforming growth factor beta (TGF-β) is critical for inflammation regulation and oral tolerance promotion. Previous reports suggested that variations in HM TGF-β levels are associated with allergic outcomes. Objective: We undertook a systematic review (PROSPERO 2017 CRD42017069920) to reassess the evidence on the relationships between HM TGF-β and allergic outcomes in children. Methods: Electronic bibliographic databases (MEDLINE, EMBASE and Cochrane Library) were systematically searched. Two independent reviewers screened reference lists, extracted the data and assessed risk of bias using the National Institute for Clinical Excellence methodological checklist. Results: A total of 21 studies were identified. Sixteen studies assessed relationships between HM TGF-β and risk of eczema; 14, allergic sensitization; nine, wheezing/asthma; six, food allergy; three, allergic rhinitis/conjunctivitis. Five cohorts (5/18, 28%) reported a protective effect of TGF-β1, while 3 (3/10, 30%) suggested increased risk of allergic outcomes development and 1 (1/10, 10%), a protective effect of TGF-β2 on eczema. Meta-analysis was not possible due to significant heterogeneity in methodology, age of outcome assessment and differing statistical approaches. 71% (15/21) of studies carried a high risk of bias. Conclusion and clinical relevance: In contrast with previous findings, we did not find strong evidence of associations between HM TGF-β and allergic outcomes. Differences in studies' methodology and outcomes do not allow unconditional rejection or acceptance of the hypothesis that HM TGF-β influences the risk of allergy development. Future studies on diverse populations employing standardized methods, accurate phenotyping of outcomes and evaluation of the effect of TGF-β in combination with other HM immune markers, microbiome and oligosaccharides are required.

Breastfeeding rates are low in the UK, where approximately one quarter of infants receive a breastmilk substitute (BMS) in the first week of life. We investigated the reasons for early BMS use in two large maternity units in the UK, in order to understand the reasons for the high rate of early BMS use in this setting. Data were collected through infant feeding records, as well as maternal and midwife surveys in 2016. During 2016, 28% of infants received a BMS supplement prior to discharge from the hospital maternity units with only 10% supplementation being clinically indicated. There was wide variation in BMS initiation rates between different midwives, which was associated with ward environment and midwife educational level. Specific management factors associated with non-clinically indicated initiation of BMS were the absence of skin-to-skin contact within an hour of delivery (p = 0.01), and no attendance at an antenatal breastfeeding discussion (p = 0.01). These findings suggest that risk of initiating a BMS during postnatal hospital stay is largely modifiable. Concordance with UNICEF Baby Friendly 10 steps, attention to specific features of the postnatal ward working environment, and the targeting of midwives and mothers with poor educational status may all lead to improved exclusive breastfeeding rates at hospital discharge.

Nowadays, the breast-feeding, despite the approved advantages, is not a standard in many communities. The multi-factorial determinants determining its prevalence need to be supported at various levels - from legal and legislative one to views and values of society, conditions of women's labor and also health care system that can develop a favorable environment for breast-feeding. The breast-feeding effects positively on health, economic development and ecology and therefor it is a benefit for children, women and whole society in short-term and long-term perspective. The defense, propaganda and support of breast-feeding need a political will, and financial investments to implement its advantages.

Assessment of the practice of breastfeeding support in a department of neonatal and premature infant pathology of the Tambov Regional Children’s Clinical Hospital (TRCCH) after 3–4 years of becoming a WHO/UNICEF Baby Friendly Hospital. Patients and methods. Mothers were questioned using specially designed questionnaires at their admission to the department and at discharge from hospital. Overall, 356 mothers were questioned at admission and 327 at discharge. The results were processed on the SPSS.19 statistical programme. Frequency distribution, mean values (± standard deviation) and Student’s t-coefficient were determined. Results. The practice of supporting breastfeeding in the department consisted in observance of the 10 steps of successful breastfeeding: mother and infant remaining together (98.2%), breastfeeding on an infant’s demand (91.3%), breastfeeding at night (98.6%), breast milk extraction for infant feeding and lactation stimulation (88.6%), informing mothers about the benefits and technique of breastfeeding (90.5%). The percentage of breastfed infants significantly increased by the time of discharge from the department – to 89.4% (at admission – 71.9%; p < 0.0001), among them exclusively breastfed infants – to 66.5% (at admission – 45.3%; p < 0.0001). Conclusion. The practice of breastfeeding based on current international recommendations is successfully supported in the neonatal department of TRCCH. Nevertheless, breastfeeding parameters might be considerably improved due to attainment of continuity in the work of maternity clinics and TRCCH and optimization of the practices of breast milk extraction, storage and use in the department.

To study the quality of life of feeding mothers and toe establish whether the adherence to breastfeeding influences physical and mental health of women. Patients and methods. We conducted a questionnaire survey of 151 mothers who had small infants. Their quality of life was studied with the help of the SF-36 questionnaire. Results. As we have found, the higher is the material wellbeing of the family, the less women adhere to breastfeeding (per capita income of the family of breastfeeding mothers are almost 2 times lower than in nonbreastfeeding women – 22500 ± 3.800 and 43958.33 ± 4.240 rubles, respectively, р < 0.05). Subjective perceptions of physical health (functioning), parameters of life activity (Vitality – VT) and subjective assessment of their health (General Health – GH) were similar in both breastfeeding and nonbreastfeeding mothers (VT 56.48 ± 3.77 and 58.33 ± 2.91; GH 68.52 ± 4.13 and 65.83 ± 1.95, р > 0.05). Irrespective of breastfeeding adherence, women after childbirth did not report of worsening of their health (50.93 ± 4.01 and 44.79 ± 2.61, respectively, р > 0.05). But in breastfeeding mothers parameters of the quality of life were demonstrative of a higher endurance (physical functioning 73.89 ± 1.66 and 85.22 ± 3.19, role functioning 52.78 ± 2.16 and 65.63 ± 3.73, р < 0.05). Breastfeeding mothers more rarely had difficulties in routine activities due to their physical condition and pain (bodily pain 73.89 ± 3.77 and131.35 ± 2.16, р < 0.05), physical and emotional condition did not interfere with communication and social activity (social functioning 67.13 ± 1.93 and 139.8 ± 6.92, р < 0.05, mental health 95.11 ± 7.18 and 58.17 ± 8.11, р < 0.05). They are less prone to depression and have higher values of the positive emotions parameter (role emotional functioning 64.08 ± 3.98 and 215.73 ± 12.67, р < 0.01). Conclusion. The results of the study can be used in programmes aimed at expanding breastfeeding.

AIM: To develop and justify optimal nutritional support in early phase of acute pancreatitis (AP).MATERIAL AND METHODS: 140 AP patients were enrolled. They were divided into groups depending on nutritional support: group I (n=70) - early enteral tube feeding (ETF) with balanced mixtures, group II (n=30) - early ETF with oligopeptide mixture, group III (n=40) - total parenteral nutrition (TPN). The subgroups were also isolated depending on medication: A - Octreotide, B - Quamatel, C - Octreotide + Quamatel. Pancreatic secretion was evaluated by using of course of disease, instrumental methods, APUD-system hormone levels (secretin, cholecystokinin, somatostatin, vasointestinal peptide).RESULTS: ETF was followed by pancreas enlargement despite ongoing therapy, while TPN led to gradual reduction of pancreatic size up to normal values. α-amylase level progressively decreased in all groups, however in patients who underwent ETF (I and II) mean values of the enzyme were significantly higher compared with TPN (group III). Secretin, cholecystokinin and vasointestinal peptide were increasing in most cases, while the level of somatostatin was below normal in all groups.CONCLUSION: Enteral tube feeding (balanced and oligopeptide mixtures) contributes to pancreatic secretion compared with TPN, but this negative impact is eliminated by antisecretory therapy. Dual medication (Octreotide + Quamatel) is more preferable than monotherapy (Octreotide or Quamatel).

To investigate the effectiveness of the application of clinical guidelines “Enteral feeding of preterm infants” in infants below 32 weeks’ gestation. Material and methods. The study comprised 114 extremely preterm infants born before (2013-2014, group 1, n=53) and after (2014-2015, group 2, n=61) introduction of the clinical guidelines. Comparative analysis included breastfeeding frequency, the time of initiation of enteral feeding and achieving enteral feeds up to a volume of 150ml/kg/d, the incidence of necrotizing enterocolitis (NEC), gastrointestinal dysfunction, gastric bleeding, the use of breast milk fortifier, and the dynamics of infant postnatal physical growth. A comparative assessment also included the length of hospital stay, postconceptional age (PCA) and body weight at the time of hospital discharge. Results. After the introduction of clinical guidelines, 47 (77%) children received maternal colostrum on the first day of life. Breastfeeding was initiated significantly earlier: within 1 (1-5) day after birth in group 2 compared with 9 (2-28) days in group 1. Most infants received enteral feeding on the first day of life, though the infants in group 2 were administered it significantly earlier [7.5 hours (3.5-51) vs. 12 (6-144)]. A significant part of the extremely preterm infants was fed with breast milk. Sixteen (30%) infants in group 1 and almost twice fewer children in group 2 [10 (16%)] were on artificial feeding. In group 2, full enteral feeding was achieved significantly earlier than in group 1 [12 days (6-48) vs. 18.5 (13-47)], while the incidence of NEC in group 2 decreased 1.7-fold (14.8% vs. 24.5%). By 36 weeks’ PCA, the infants in group 2 had significantly higher body weight than babies in group 1 [2220 g (1420-2818) vs. 2050 g (950-3190)]. Conclusion. The clinical implementation of the guidelines “Enteral feeding of preterm infants” has resulted in significantly higher feeding efficiency in extremely preterm babies.
