Antibiotics are frequently administered during pregnancy. Although necessary to address acute infections, their use facilitates antibiotic resistance. Other associations have also been found with the use of antibiotics, such as perturbations of gut bacteria, delays in microbial maturation, and increased risks of allergic and inflammatory diseases. Little is known about how the prenatal and perinatal administration of antibiotics to mothers affects the clinical outcomes of their offspring. A literature search was conducted of the Cochrane, Embase, and PubMed engines. The retrieved articles were reviewed by two authors and verified for relevance. The primary outcome was the effect of pre- and perinatal maternal antibiotic use on clinical outcomes. Thirty-one relevant studies were included in the meta-analysis. Various aspects are discussed, including infections, allergies, obesity, and psychosocial factors. In animal studies, antibiotic intake during pregnancy has been suggested to cause long-term alterations in immune regulation. In humans, associations have been found between antibiotic intake during pregnancy and different types of infections and an increased risk of pediatric infection-related hospitalization. A dose-dependent positive association between pre- and perinatal antibiotic use and asthma severity has been reported in animal and human studies, while positive associations with atopic dermatitis and eczema were reported by human studies. Multiple associations were identified between antibiotic intake and psychological problems in animal studies; however, relevant data from human studies are limited. However, one study reported a positive association with autism spectrum disorders. Multiple animal and human studies reported a positive association between pre- and perinatal antibiotic use by mothers and diseases in their offspring. Our findings have potentially significant clinical relevance, particularly considering the implications for health during infancy and later in life as well as the related economic burden.

Purpose: Infantile colic diagnostic criteria were established by Rome IV. A universally accepted management remains to be established. We aimed to evaluate diagnostic criteria, management strategies, and perceived regional prevalence of infantile colic in Pakistan, as well as its effect on physicians and parents. Methods: A questionnaire was distributed amongst 1,256 physicians. Results: We received 800 replies. Wessel and Rome IV criteria were used by most physicians for diagnosis; however, the response "any infant who cries a lot" was selected by older physicians (48% of those over 60 years), physicians in rural areas (32%), physicians practicing in private clinics (27%), and general physicians (30%). Estimated prevalence of infantile colic ranges from 21-40%. Reassurance was the most widely recommended management strategy followed by herbal teas (51%), switching to a different formula (49%), probiotics (28%) and antibiotics (26%), discontinuation of breastfeeding (14%), elimination of dairy products from the breastfeeding mothers' diet (6%), and the administration of colic drops (1%). Most physicians considered the negative impact of colic on their personal lives and the parents as mild-to-moderate. Notably, 38% of percent of physicians routinely screened for maternal depression, and 45% of physicians were aware of the association between infantile colic and shaken baby syndrome. Conclusion: Most physicians in Pakistan diagnose and manage infantile colic according to the established guidelines. However, the guidelines pertaining to treatment planning are not followed. Educational efforts directed toward general physicians and doctors practicing in rural areas and clinics must be implemented to avoid unnecessary testing and treatment burden.

Mother and infant relationship has a great influence on child's developments. Expecially, mother and infant relationship is affected by mother and infant interactions during one year after birth and an omen of mother-infant interaction after birth is mother-fetus interaction. This study was conducted to develop mother-fetus interaction promotion program of talking and tactual stimulation aimed at enhancing sensitivity of primiparas and to evaluate the effect of the nursing intervention program on mother-fetus interaction and mother-infant play interaction. Non-eguivalent control group posttest design was used, and Blumer's symbolic interaction theory and Barnard's mother-infant interaction model was used a conceptual framework of this study. Fifty primiparas and infant(26 mother-infant dyads for intervention group and 24 dyads for control group) were recruited from three general hospital and an OBGY clinic located in Kwang Nung city. Data was collected from January 30th to December 20th in 2001. For the intervention group, programed education which focused on mother-fetus interaction in the 1st trimester. Telephone counselling was provided with interval of two weeks. For two groups, home visiting for data collection of mother- fetus interaction was conducted at 36 to 38 weeks of gestational age. And mother-infant play interactions were assessed at 4 to 6 weeks after birth using videotapes. Play situations were videotaped and two trained observers analyzed the tapes. The data were analyzed using chi-square test and Fisher's Exact Test to test the equivalence of two groups, and the effect of intervention progrom was determined with t-test and Wilcoxon Rank Sum test. The results were as follows: 1. The significant difference was found in mother-fetus interaction between two groups(t=2.085, P=0.0425). It indicated that intervention progrom was effective in improving mother-fetus interaction. 2. The significant difference was found in mother-infant play interaction between two groups(W=347.5, P=0.0001). In subscale analysis, three subscales showed significant differences between the groups: interactional behavior of mother(t=5.921, P=0.0001), interactional behavior of infant(t=5.736, P= 0.0000), and synchronic interactional behavior of mother and infant(t=7.940, P= 0.0000). In conclusion, this study has shown that the applied nursing intervention aimed at enhancing sensitivity of primiparas promoted mother-fetus interaction and mother-infant play interaction. Therefore, this study suggests that this nursing interventions to increase maternal sensitivity to the fetus's movement should be broadly applied to primiparas, which can be beneficial for formation of mother - infant relationship, and for promotion the social, affective, and cognitive developments of their children.

The studies of M. Colombo (1989) and W. Lange (1992) showed that 30~40% of people became chronic after suffering from hepatitis B virus (HBV) and C virus (HCV) infection, and about 50% of the chronic cases transformed into primary liver cancer. There have been few studies done in Mongolia on hepatitis infection among health professionals, particularly in nurses. In a study done by Chimedsuren (8), the study showed that 19.4% of people with identified surface hepatitis B antigen (HBsAg) and antibodies to hepatitis C virus and 8% of people with the identified nucleotide of RNA for the hepatitis C virus (polymerase chain reaction) had an acute form of hepatitis C. Studies on the hepatitis virus genome damaging effect on liver cells showed that genotype 8 (A, B, C, D, E, F, G, TTV) had the most damaging effect on liver cells (Hahn and Faeka, 2007). Several studies have shown a relationship between hepatitis B virus infection and a lack of compliance regarding safety regulations and rules by medical personnel. Results of a study from the Maternal and Child Health Research Center showed that tests done to detect hepatitis B virus antigen and antibodies to C virus did not reveal anything. Both antigen and antibodies in 69% cases did not show, and separately, B virus and antibodies to hepatitis C virus were identified in 13% and 9%, respectively. Results of the tests taken from health personnel in Shastin Central Hospital showed that in 76% of the cases, the B virus antigen with C virus antibodies was not identified. In 8% of the cases, the B virus antigen was present on its own. The combination of B the virus antigen and C virus antibodies were present in 8% of nurses and doctors, respectively. 82% of the cases had negative results for the detection of a combination of B virus antigen and C virus antibodies taken from health personnel from the State Central Clinical Hospital whereas the B virus antigen and C virus antibodies by themselves were present in 7% and 14% of the cases, respectively. Combined cases of the B virus antigen and C virus antibodies were identified in 4% of the personnel. Results of the tests taken from the health personnel in the Hospital of the Ministry of Justice and Internal Affairs showed that in 79% of the cases, the B virus antigen with C virus antibodies were not identified. Separately, the B virus and antibodies to hepatitis C virus were identified in 8% and 13% of the cases, respectively.

This study was performed to investigate the effect of human follicular fluid (HFF) on development of mouse embryos, for evaluating the suitability of HFF as a substitutive material of human fetal cord serum in ART program. The various concentrations of HFF were added into the culture medium and the effects of HFF concentrations were examined to identify the optimal concentration of HFF for embryo development. The potency of HFF in improving embryo development was compared to that of other protein supplement. Collected HFFs were classified with the maturity of the containing oocytes; mature, immature, atretic, and then the effects of the classified HFFs on embryo development were examined. Also, HFF was separated into the low (<30,000 Da) and high (>30,000 Da) molecular weight fractions and the effects of the fractions on embryo development were investigated. The highest development rate was found in culture medium supplemented with 20% HFF, bnt this rate was reversely reduced at the concentrations of HFF higher than 20%. The development rates to the blastocyst, hatching blastocyst, attachment and outgrowth cultured in mature HFF was significantly higher than those in immature and atretic HFF, and mean cell number in blastocyst was higher in mature HFF than in immature and atretic HFF. The development rates of mouse embryos according to protein sources were significantly higher in HFF than in fetal cord serum (FCS), maternal serum (MS) and bovine serum albumin (BSA), and mean cell number in blastocyst cultured in HFF was higher than that in FCS, MS and BSA. The development rates of embryo and mean cell number in blastocyst cultured in high molecular weight fraction of HFF were higher than those in low molecular weight fraction, but the results of high molecular weight fraction were lower than those of whole HFF. Therefore, these results indicated that human mature follicular fluid was useful for improving the development of mouse embryos, which suggests a possibility that HFF also may be used efficiently for improving the culture condition in human ART program as a protein supplement.

The purpose of this study was to identify the trends and contents of intervention towards children using meta analysis, to support the basis for using in the field and research method about nursing intervention. We used 27 materials which was reported from 1970 to August, 1999 : dissertation study and Korean Nurses' Academic society Journals, the Journal of Korean Academic society of Adult Nursing, The Korea Journal of Maternal and Child Health Nursing. The types of intervention we used came from 3 different researchers. Snyder showed cognitive, movement, social sensory intervention. McCloskey & Bulechek categorized as the following : self-care assistance, acute care management, life-style alteration, health promotion, life support intervention, Craft & Denehy classified psychosocial intervention and biophysiological intervention. Some findings are summarized as follow : Out of the 27 researches sensory intervention had the most in there thesis, recently cognitive intervention research has a tendency to increase. 18 researches has acute care management in there theses, and health promotion was found the least. Out of the 27 thesis 15 thesis was classified as biophysiological intervention and 12 had psychosocial. 27 thesis had 11 types of interventions which originally was categorized by Snyder, therefore sensory intervention thesis had the most. 11 types of intervention which originally was classified by McClosky & Bulechek, teaching and information had the most out of acute care management. Out of 27 thesis, 14 had dealt with newborns, especially newborns with sensory intervention. Therefore school age and above had cognitive intervention which was used for teaching and information. Infants, preschool, schoolage children received acute care management the most, health promotion intervention was used towards adolescences. Depending on the characteristics of dependent variables, it was analysed using meta however 17 thesis are possible except primary experimental research. Mean effect size comparison by Snyder classification, cognitive intervention was the largest mean(1.51), sensory intervention was larger(0.71) also, movement intervention was in the middle(0.56) as shown. Comparison done by McClosky & Bulechek, the intervention leading to life style alteration was the largest mean(1.97), teaching was used the most. Comparison by Craft & Denehy classification, psychosocial intervention was larger(1.15) than biophysiological intervention (0.67). The result of nursing intervention through age classification, the largest weighted mean effect size in the research was towards infants and neonates. The research which was focused on nursing intervention, has important meaning in nursing practice and knowledge development. When we know that children's nursing intervention is necessary and overcome our biased view, efficiency of children's nursing intervention are increased and professionalized. Therefore results will be important basic data to guide a development of child nursing intervention & classification.
