In recent publications, positive results have been reported with the use of glasses with red protective filters in prematurely born infants with low body weight, which were presumably associated with a decrease in the levels of illumination of the environment of the child. However, to date, it has not been proven that a decrease in the amount of light reaching the retina of the newborn affects the frequency and severity of retinopathy of prematurity (RP). The analysis of the literature on the therapeutic effect of various modes of red and near infrared radiation on the retina is presented, which allowed a different look at the protective mechanisms of glasses-filters in premature babies. It has been suggested and substantiated that the observed effect may relate to the phenomenon of pre-conditioning photostimulation, which reduces the risk of developing RP and reduces the severity of the disease due to the induction of adaptive plastic reactions in the retina.

Background. Medical care for premature babies in Germany is divided into two levels. Perinatal centers of the first level provide care for infants with body weight at birth <1500 g. Perinatal centers of the second level provide care for children whose body weight exceeds 1500 g. In order to be included in the list of first level institutions, the hospital must, among other, be able to pick up children from other institutions in the surrounding region. Mobile incubators are used for this purpose. Such an incubator is a kind of a mobile intensive care unit. In some cases, the incubator is delivered to the desired location by helicopter, but in most cases, specialized road transport is used. Objective. To describe neonatological medical care in Germany. Materials and methods. Analysis of own experience and available literature data on this issue. Results and discussion. In recent years, Germany experiences a decrease in the number of births, which causes the problem of professional training of doctors. Hospitals with the fewest births are closed due to lack of efficiency. Although there are some fluctuations from year to year, in general, the number of premature babies with extremely low birth weight remains approximately constant. Prematurity remains one of the most important problems of modern medicine, as it is accompanied by high mortality rates. The earlier the premature birth is and the lower the body weight is, the higher these rates are. Prematurity is caused by numerous risk factors. Multiple pregnancies are accompanied by the highest risk of premature birth. The presence of twins or triples increases this risk by 7.7 times. Other risk factors include vaginal bleeding in late pregnancy, preeclampsia, and a history of preterm birth. Over the past 20 years, the survival of children born before 32 weeks of pregnancy or weighing <1500 g has increased by almost 20 %. The smallest premature baby born in our clinic is a baby born at 24 weeks of gestation with a body weight of 350 g. Nowadays in Germany, the survival rate of infants born after 24 weeks of gestation is almost 80 %, and after 29 weeks – almost 100 %. It should be noted that maintaining the life of a premature baby from birth to discharge costs 250-300 thousand euros. Bronchopulmonary dysplasia is an important problem of premature infants, especially in case of mechanical lung ventilation (MLV) or joining infections. Up to 40 % of children who die from complications of bronchopulmonary dysplasia can be saved. If possible, MLV and infections should be avoided, premature births should be prevented, so-called neuroprotective ventilation and nasal or mask devices that do not require intubation should be used. Surfactants have made great progress in the management of premature infants. The modern LISA (less invasive surfactant administration) method allows to inject a surfactant into a child’s lungs without intubation. In the early 20th century, 100 % oxygen was used in the resuscitation of newborns, but now we use air (21 % oxygen) or a mixture containing up to 30 % oxygen. To prevent necrotizing enterocolitis, premature infants are prescribed probiotics based on lyophilized lactic acid bacteria and bifidobacteria. Breast milk is an another way to prevent this complication of prematurity. There is a breast milk bank in Potsdam. Conclusions. 1. Prematurity remains one of the most important problems of modern medicine, as it is accompanied by high mortality rates. 2. Multiple pregnancies are accompanied by the highest risk of premature birth. 3. Nowadays in Germany, the survival rate of children born after 24 weeks of gestation is almost 80 %, and after 29 weeks – almost 100 %. 4. Surfactants and the LISA method have made great progress in the management of premature infants. 5. Probiotics and breast milk are prescribed to premature babies to prevent necrotizing enterocolitis.

Anemia Of Prematurity

Anemia of prematurity is a common pathology in premature infants. The prevalence of anemia of prematurity is inversely proportional to the gestational age and body weight at birth. The pathogenetic importance of impaired erythropoietin (EPO) production in anemia of prematurity provides the rationale for therapy with erythropoiesis stimulating agents (ESAs) including recombinant EPO. A comparative analysis of the effectiveness of different regimens of recombinant human erythropoietin in extremely and very low birth weight infants (ELBW and VLBW) was studied. Research has been set as a prospective analysis of 133 VLBW and ELBW infants (in the period from December 2017 to February 2019). Gestational age (GA) of the children ranged from 26 to 33 weeks, of these, GA of 75 children (56%) was 30 weeks or less. Depending on the treatment of anemia of prematurity all infants were divided into 5 groups: group 1 (n = 26) – premature babies who were prescribed ESAs since 3 day of life 200 IU/kg 3 times per week subcutaneously; group 2 (n = 21) – premature babies who were prescribed ESAs since 3 day of life 400 IU/kg 3 times per week subcutaneously; group 3 (n = 37) – premature babies who were prescribed ESAs since 8 day of life 200 IU/kg 3 times per week subcutaneously; group 4 (n = 18) – premature babies who were prescribed ESAs since 8 day of life 400 IU/kg 3 times per week subcutaneously; group 5 (n = 31) premature infants who did not receive treatment with recombinant human erythropoietin (control group). Subgroups of children of gestational age ≤ 30 weeks were identified in each group. The groups and subgroups did not differ significantly in gestational age, weight, birth length, and Apgar score at 1 and 5 minutes of life, p > 0.05. Also, there were no statistically significant differences in the age of the 1st transfusion, the frequency and total volume of transfusions, the duration of respiratory therapy, the duration of hospitalization, including treatment in NICU, body weight and age at discharge. The frequency of retinopathy of prematurity stage ≥ 3, periventricular leukomalacia, bronchopulmonary dysplasia of moderate and severe severity, intraventricular hemorrhages of varying severity, necrotizing enterocolitis was not statistically significant in the study groups and subgroups. Statistically significant differences in the concentration of hemoglobin in the peripheral blood of premature infants were revealed at discharge. In the control group, children had a lower level of hemoglobin at discharge (94 g/l) compared with the groups with early appointment of ESAs (109 g/l and 107 g/l in groups 1 and 2, respectively, P0-1 = 0.048 and P0-2 = 0.047) due to newborn GA ≤ 30 weeks. It is preferable to use of the drug ESAs at a dose of 200 IU/kg 3 p/week p/, starting from the 3rd day of life. The effectiveness of erythropoietin therapy, the time of its start and various treatment regimens remain controversial issues that require further study. The study was approved by the Independent Ethics Committee of the National Medical Research Center for Obstetrics, Gynecology and Perinatology named after Academician V.I. Kulakov.

Background: Premature infants have a risk of death in the first year of life mainly due to prematurity. Developmental stimulation interventions in premature infants can have a positive impact on weight gain and infant development. The purpose of this study was to determine the effect of the application of growth and development intervention booklets on mothers who had a premature baby to increase the growth and development of infants aged 0-6 months in Karanganyar Regency. Method: The method used in this study is the method in this study. This research uses a quantitative method with a Quasy experiment in the form of a pre-post test design. The sample in this study was Mother and Baby in Karanganyar District who had met the inclusion and exclusion criteria. Results: The results of this study showed that there were differences in body weight and height growth before and after the study in the control group (ρ <0.05). There were no differences in development before and after the study in the control group (ρ> 0.05). There were differences in body weight and height growth before and after the study in the intervention group (ρ <0.05). There are differences in development before and after the study in the control group (ρ <0.05). There is no effect of the application of growth intervention booklet stimulation, but there is a developmental influence on premature infants aged 0-6 months in Karanganyar Regency. Conclusion: SDIDTK booklet can significantly improve the development of premature babies. It is expected that parents can provide stimulation to premature babies well to increase growth and development

The study and monitoring of international indicators of the health status of premature infants is the current vector of scientific research in neonatology.Objective. To assess the effectiveness of the nursing technologies of premature babies in the Republic of Belarus based on the analysis of long-term indicators of morbidity, mortality and survival of the infants with extremely low body weight.Material and methods. Statistical reports data were used for a retrospective analysis of epidemiological indicators for the period of 2002–2018.Results. The proportion of premature infants in the Republic of Belarus was stabilized at 4,2–4,5% increase in the absolute numbers, including those born weighing less than 1500 g. The ratio of the absolute number of alive and stillborn infants with extremely low body weight is many times higher than the initial values (p<0,05). The survival rate of infants with a body weight of 500–999g up to 1 year increased 2 times to the maximum level in 2018 (81,5%). There was an increase in the overall incidence of premature children in 2002–2010 (p<0,05) and a decrease by 2016 (p=0,001), including those born with a body weight of 500–999 g. Respiratory distress syndrome, intrauterine hypoxia and asphyxia during childbirth, an increase in the frequency of infections specific to the perinatal period (p <0,05) were registered more often. Among the children born with a body weight of 500–999 g, the incidence of congenital pneumonia for the period 2002–2009 increased to a maximum level of 263,4 ‰ (p <0,05) with a twofold decrease by 2018. The republican mortality rate of premature babies was stabilized at the level of 0,95 ‰ in the last 9 years, while the indicator was decreased 5 times among children weighing 500–999 g.Conclusion. The assessment of the long-term dynamics of the main indicators of the health status of premature infants in the Republic of Belarus testified to the effectiveness of a complex of organizational and medical measures for their nursing.

AbstractIn eusocial honey bees, Apis mellifera, diet, gut microbiota and nestmates can all contribute to the health of freshly emerged individual workers, but their relative importance for longevity and body weight is currently unknown. Here, we show that diet is most relevant, followed by gut microbiota and the presence of nestmates. Freshly emerged workers were randomly assigned to eight treatments (with or without honey/pollen, protein-substitute lactalbumin, antibiotic tetracycline and nestmates for 24 h) and maintained under standardised laboratory conditions. Longevity and food consumption were measured daily and fresh body weight was assessed at day 7. The data show a significantly better survival and a higher body weight in workers supplied with honey/pollen. Survival was higher in the lactalbumin treatments compared to the ones restricted to sucrose only, but lower compared to those with honey/pollen, highlighting the importance of micronutrients. In contrast, antibiotic treatment had a significant negative effect on longevity and body weight, which may be explained by inactivated gut microbiota and/or toxicity of the antibiotics. There was no positive effect of nestmates, probably due to the short exposure period. In contrast, nestmates showed a negative effect on survival in antibiotic-treated workers, possibly by transmitting pathogens and antibiotic-induced gut dysbiosis. In conclusion, a macro- and micronutrient-rich diet appears to be the key to individual honey bee worker health. Providing an optimal diet and possibly gut microbiota appears to be a promising way to promote managed A. mellifera health.

AbstractBreast cancer is the most common cancer that causes death in women. Conventional therapies, including surgery and chemotherapy, have different therapeutic effects and are commonly associated with risks and side effects. Near infrared radiation is a technique with few side effects that is used for local hyperthermia, typically as an adjuvant to other cancer therapies. The understanding of the use of near NIR as a monotherapy, and its effects on the immune cells activation and infiltration, are limited. In this study, we investigate the effects of HT treatment using NIR on tumor regression and on the immune cells and molecules in breast tumors. Results from this study demonstrated that local HT by NIR at 43 °C reduced tumor progression and significantly increased the median survival of tumor-bearing mice. Immunohistochemical analysis revealed a significant reduction in cells proliferation in treated tumor, which was accompanied by an abundance of heat shock protein 70 (Hsp70). Increased numbers of activated dendritic cells were observed in the draining lymph nodes of the mice, along with infiltration of T cells, NK cells and B cells into the tumor. In contrast, tumor-infiltrated regulatory T cells were largely diminished from the tumor. In addition, higher IFN-γ and IL-2 secretion was observed in tumor of treated mice. Overall, results from this present study extends the understanding of using local HT by NIR to stimulate a favourable immune response against breast cancer.

Background: Nutrition plays an important role in maintaining the overall health of older people. Inadequate intake may lead to impaired body function, higher morbidity, and mortality. Oral nutritional supplements (ONS) showed positive effect on the nutritional status of the elderly; however, systematic evidence is currently lacking on the effect of ONS on the elderly with anorexia. Aims: The current systematic review and meta-analysis included randomized controlled trial (RCT) articles to investigate the effectiveness of ONS on the main aspects of anorexia of aging (AA). Methods: By using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method, researchers independently searched PubMed/MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Library, China National Knowledge Infrastructure (CNKI) and other gray literature resources for publications that met the inclusion criteria by October 2020. The Cochrane Risk of Bias Tools were used for quality assessment. The inverse-variance method was used for the fixed model (FM) while the DerSimonian–Laird method was used for the random model (RM). Respective 95% confidence intervals (95% CIs), mean difference (MD) or standardized mean difference (SMD) was used for indices in terms of effect size (ES). Results: 2497 records were found through the systematic search, while 17 RCTs (n = 1204) were included, with a mean age of 81.9 years (range: 74–87 years). Supplementation occurred in the morning, mid-day, and evening, while the times varied from one to three times a day. The results of meta-analysis showed that, generally, ONS had a positive effect on the overall appetite, MD = 0.18, 95% CI (0.03, 0.33), p = 0.02, and consumption, MD = 1.43, 95% CI (0.01, 2.86), p = 0.05; but not significant in terms of other aspects of appetite: hunger, p = 0.73; fullness, p = 0.60; desire to eat, p = 0.80; preoccupation, p = 0.15. Additionally, it showed an increase in the overall energy intake, SMD = 0.46, 95% CI (0.29, 0.63), p < 0.001, in protein intake, SMD = 0.59, 95% CI (0.16, 1.02), p = 0.007, and in fat intake, MD = 3.47, 95% CI (1.98, 4.97), p < 0.001, while no positive effect was found on carbohydrates intake, p = 0.06. Significance differences were also found in the body weight, SMD = 0.53, 95% CI (0.41, 0.65), p < 0.001, and body mass index (BMI), MD = 0.53, 95% CI (0.12, 0.95), p = 0.01. Moreover, subgroup analyses were conducted according to the nutrient density with no positive results showed except for the low-density ONS on overall energy intake. Conclusions: The results of the present study indicated that ONS had beneficial effects on overall appetite, energy intake, body weight and BMI.
