Abstract
PURPOSE To assess the incidence of MRSA positive patients in pregnancy, as well as the postpartum outcomes in MRSA positive patients. METHODS This is a retrospective cohort study of women who underwent universal MRSA universal at a tertiary medical center. A MRSA swab was routinely collected as part of the patient's prenatal care at 35-37 weeks gestation or on admission to labor and delivery. Demographic information and decolonization antibiotics were collected by electronic medical record review, using ICD-9 codes. Outcome data were collected, including mode of delivery, hospital length of stay, endometritis, wound cellulitis, and wound infection. p < 0.05 was considered significant. A univariate logistic regression and a multivariable binary logistic regression model were used to analyze the strength of association between outcomes and MRSA status. Statistical analysis was performed with SAS, version 9.4. RESULTS The incidence of MRSA during the 4 year study period was 1.9% (82 MRSA positive out of 4369 total patients). 90.2% (74/82) of MRSA positive patients received decolonization antibiotics. No difference was noted in mode of delivery. Logistic regression failed to identify any significant differences in other relevant outcomes for MRSA positive women including endometritis 1.1 (0.1-17.5) [positive 0, versus negative 0.6% (n = 24)], wound cellulitis 5.9 (0.4-82.1) positive 0, versus negative 0.1% (Gorwitz et al. in J Infect Dis 197:1226-1234, 2008) and wound infection 3.3 (0.6-16.9) [positive 1.2%, versus negative 0.5% ( in Am J Infect Control 32:470-85, 2004)] when compared to MRSA negative women. CONCLUSION When universal MRSA screening was performed at an academic tertiary care center, the overall incidence of MRSA was low. MRSA positive and subsequently decolinzed patients did not have any identified increase in postpartum infectious morbidity, as compared to MRSA negative patients.

Abstract
INTRODUCTION Antibiotics are life-saving drugs but irrational/inappropriate use leads to the emergence of antibiotic-resistant bacterial superbugs, making their treatment extremely challenging. Increasing antimicrobial resistance (AMR) among bacterial pathogens is becoming a serious public health concern globally. If ignorance persists, there would not be any antibiotics available to treat even a common bacterial infection in future. AREA COVERED This article intends to collate and discuss the potential of 4D's (right Drug, Dose, Duration, and De-escalation of therapy) approach to tackle the emerging problem of AMR. For this, we searched PubMed, Google Scholar, Medline, and clinicaltrials.gov databases primarily using keywords 'optimal antibiotic therapy,' 'antimicrobial resistance,' 'higher versus lower dose antibiotic treatment,' 'shorter versus longer duration antibiotic treatment,' 'de-escalation study', and 'antimicrobial stewardship measures' and based on the findings, form and expressed our opinion. EXPERT OPINION More efforts are needed for developing diagnostics for rapid, accurate, point-of-care, and cost-effective pathogen identification and antimicrobial susceptibility testing (AST) to facilitate rational use of antibiotics. Current dosing and duration of therapies also need to be redefined to maximize their impact. Furthermore, de-escalation approaches should be developed and encouraged in the clinic. This altogether will minimize selection pressure on the pathogens and reduce emergence of AMR.

Abstract
INTRODUCTION: According to the data by World Health Organization, the broad and often insufficiently substantiated prescription of antibiotics, including for prophylactic purposes, has led to the growth of antibiotic-resistant microflora, which is a dangerous and intractable problem of modern medicine. Despite the undoubted benefits of antibiotics in the management of wound infection and endometritis after cesarean section, the routine prophylactic administration of antibacterial drugs can not only carry the risk of growth of resistant nosocomial microflora, but also have doubtful effects on the health of a newborn.
PURPOSE OF THE STUDY: The purpose of the study was to justify the possibility of carrying out elective cesarean section operations without routine antibiotic prophylaxis.
MATERIALS AND METHODS: An analysis of 333 cases of elective cesarean section operations carried out in the obstetric department in the period from 2017 to 2019 was performed. Routine antibiotic prophylaxis before surgery was not prescribed in 118 healthy patients with an uncomplicated history and a smooth course of the gestational process. The remaining 215 women received a single intravenous injection of 1 g of cefazolin sodium intraoperatively, after extraction of the fetus. A comparative analysis of the clinical groups was carried out according to the following criteria: vaginal microbiocenosis before surgical delivery, duration, and features of the operation, clinical blood count on days 1 and 5 of the post-operative period, condition of postoperative sutures, the presence of discharge from the wound, signs of infectious complications from the uterus or other organs, uterine involution rate, duration of hospital stay before and after surgery, follow-up history for 1 month after discharge from the maternity ward. The data obtained were subjected to statistical processing.
RESULTS: We have found no significant differences in the course and number of complications in the postpartum period in the compared clinical groups. The statistically significant transient leukocytosis observed on the 1st day of the postoperative period in patients who did not undergo antibiotic prophylaxis before the surgery seems to be associated with a more pronounced adaptive reaction and was not combined with any clinical symptoms of development of infection.
CONCLUSION: No relationship has been identified between the routine prescription of antibiotics before or during an elective cesarean section and the risk of developing infectious complications in the post-operative period. Antibiotic prophylaxis before surgery should be carried out differentially, taking into account the history and features of the course of this pregnancy.

Abstract
PURPOSE To summarize the available evidence to explore the effect of different prophylactic cefazolin regimens on postoperative surgical site infection after cesarean section. METHODS We searched WOS, Pubmed, and EMBASE Database also traced citations in the reference sections of the retrieved studies. English search words: Cesarean section, Surgical site infection, Cefazolin. The majority of the literature are randomized controlled trials comparing varied regimens of cefazolin. RESULTS A total of 11 randomized controlled trials and 4 non-randomized controlled trials involving 16,328 pregnant women were eligible. There was no statistically significant difference in the risk of SSI after cesarean section when cefazolin was given at a high dose compared with cefazolin at a low dose (OR 0.77, 95% CI 0.57-1.04, I2 = 0.0%). The risk of SSI after cesarean section was reduced by prophylactic use of cefazolin before skin incision compared with that after the umbilical cord clamping (OR 0.48, 95% CI 0.29-0.82, I2 = 53.4%). Because of the extreme heterogeneity of the combined drug use, no meta-analysis results were provided. The consequences of cefazolin combined with other antibiotics (either orally or intravenously) vary widely. For pregnant women with different risk factors, cefazolin alone or the type, dose and drug route of cefazolin combined with additional antibiotics need to be further studied and explored. CONCLUSIONS All in all, this article illustrates a better use of cefazolin for the control of Surgical incision site infection in the cesarean section. For pregnant women with cesarean section without high-risk factors of infection, the use of cefazolin is effective, but for pregnant women with different high-risk factors, the specific use of prophylactic antibiotics needs to be further explored.

Abstract
Antimicrobial prophylaxis during surgery aims to prevent post-operative site infections. For fetal surgery, this includes the fetal and amniotic compartments. Both are deep compartments as drug equilibrium with maternal blood is achieved relatively late. Despite prophylaxis, chorio-amnionitis or endometritis following ex utero intrapartum treatment or fetoscopy occur in 4.13% and 1.45% respectively of the interventions. This review summarizes the observations on two commonly administered antimicrobials (cefazolin, clindamycin) for surgical prophylaxis during pregnancy, with emphasis on the deep compartments. For both compounds, antimicrobial exposure is on target when we consider the maternal and fetal plasma compartment. In contrast, amniotic fluid concentrations-time profiles display a delayed and much more blunted pattern, behaving as deep compartment. For cefazolin, there are data that document further dilution in the setting of polyhydramnios. Along this deep compartment concept, there is some accumulation during repeated administration, modeled for cefazolin and observed for clindamycin. The relative underexposure to antimicrobials in amniotic fluid may be reflected in the pattern of maternal-fetal complications after fetal surgery, and suggest that antimicrobial prophylaxis practices for fetal surgery should be reconsidered. Further studies should be designed by a multidisciplinary team (fetal surgeons, clinical pharmacologists and microbiologists) to facilitate efficient evaluation of antimicrobial prophylaxis.
