Abstract
Urinary tract morbidity has increased by 7% in Kazakhstan between 2007 to 2011. Pregnant women with extragenital pathologies or kidney diseases had the greatest prevalence of morbidity. Asymptomatic bacteriuria (AB) is one of the most important risk factors of pyelonephritis development in pregnant women, and it can affect the course and outcome of pregnancy, delivery, and postnatal period. AB prevention requires prevention of pregnancy complications including early diagnostic of urinary tract infections, timely optimization of therapy at outpatient facilities, and dynamic follow-up.

Abstract
Maternal hypertension associated with renal disease is a common pregnancy complication. Previously, we have shown in a rabbit model of mild hypertension that offspring from hypertensive mothers have increased blood pressure as adults. In human pregnancy, hypertension has been associated with decreased utero-placental blood flow. The aim of this study was to determine placental blood flow (PBF) in mild (2-kidney-1-wrapped; 2K-1W) and moderate (2-kidney-2-wrapped; 2K-2W) rabbit models of maternal hypertension. We hypothesized that PBF would be inversely related to the severity of the hypertension. PBF and renal blood flow (RBF) were measured using microspheres on day 28 of a 32-day gestation, in normotensive (sham), 2K-1W, and 2K-2W hypertensive groups. Mean arterial pressure (MAP, ∼7 mmHg, P < 0.05) was increased, and RBF (∼35%, P < 0.05) was reduced in the 2K-1W and 2K-2W (MAP ∼20 mmHg, P < 0.01; RBF ∼53%, P < 0.05) groups compared with the sham group. In the 2K-1W group, PBF fell by ∼12% ( P = 0.08) and fetal-to-placental weight ratio increased by ∼12% ( P < 0.01) compared with the sham group, reflecting an increase in the functional capacity of the placenta to deliver nutrients to the fetus. In the 2K-2W group, PBF decreased ∼51% ( P < 0.05) compared with the sham group, without changes in placental efficiency. Thus, in late gestation, placental blood flow was significantly reduced in the moderate hypertension group, without accompanying changes in fetal or placental weight or placental efficiency. In contrast, mild hypertension resulted in an increase in placental efficiency, without significant changes in placental blood flow. These findings suggest that mild and moderate hypertension may alter placental delivery of nutrients via differing mechanisms dependent upon the severity of the hypertension.

Abstract
BACKGROUND Maternal and fetal complications in pregnancies after renal transplantation have been highlighted in several reports, but information on their main predisposing factors is limited. The U.K. Transplant Pregnancy Registry was established in 1997 to obtain detailed information on pregnancies in female organ transplant recipients across the U.K. METHODS For each female kidney, liver, or cardiothoracic organ transplant recipient who had had a recent pregnancy, data on maternal and fetal factors and pregnancy outcomes were collected using forms completed by their transplant follow-up and obstetric units. For kidney transplant recipients, the factors that influence pregnancy outcome were studied using logistic regression, and the effect of pregnancy on graft function was analyzed. RESULTS There were live births in 83%, 69%, and 79% of pregnancies in cardiothoracic organ, liver, and kidney recipients, respectively. In 50% of live births from renal patients, delivery was preterm (<37 weeks), with 83% of the preterm infants delivered via caesarean. Preterm delivery was associated with maternal drug-treated hypertension and impaired renal function. A matched case-control study showed no evidence of increased renal allograft loss after pregnancy. A univariate survival analysis, however, suggested an association between drug-treated hypertension during pregnancy and poorer postpregnancy graft survival. In patients with prepregnancy serum creatinine (SCr) >150 micromol/L, a trend toward increased postpregnancy SCr was identified. CONCLUSIONS Pregnancy is likely to end in a live birth in a majority of organ transplant recipients. In patients with greater prepregnancy SCr and/or drug-treated hypertension during pregnancy, however, subsequent renal function may be adversely affected.

Abstract
Pregnancy, although rare in the patient with end-stage renal disease, is not uncommon in the transplant recipient. Physicians taking care of transplant recipients must be able to inform patients about the potential risks of pregnancy in this setting. The patient and her partner must know that the risks associated with pregnancy increase with worsening kidney function and hypertension. Current consensus opinion is that pregnancy can be relatively safely undertaken by 1 year after transplant if the patient has had no rejections during the year, allograft function is adequate, there are no infections that could affect the fetus, the patient is not taking teratogenic medications, and immunosuppressive medication dosing is stable. Consideration must be given to immunosuppression during pregnancy both with respect to the specific agents as well as the level of dosing. None of the medications are FDA category A; all are B or higher. Part of planning for pregnancy should include an evaluation of immunosuppression medication and a plan to modify the regimen prior to conception if its use may be risky for the developing fetus. Rejection can occur during a kidney transplant, so maintaining adequate immunosuppression is important. Other issues that need to be managed when caring for a pregnant transplant patient include: potential for infection (urinary tract infections are very common), hypertension, and anemia. The type of delivery, posttransplant contraception, and breast-feeding also need to be addressed.

Abstract
The purpose of this review was to examine the impact of varying degrees of renal insufficiency on pregnancy outcome in women with chronic renal disease. Our search of the literature did not reveal any randomized clinical trials or meta-analyses. The available information is derived from opinion, reviews, retrospective series, and limited observational series. It appears that chronic renal disease in pregnancy is uncommon, occurring in 0.03-0.12% of all pregnancies from two U.S. population-based and registry studies. Maternal complications associated with chronic renal disease include preeclampsia, worsening renal function, preterm delivery, anemia, chronic hypertension, and cesarean delivery. The live birth rate in women with chronic renal disease ranges between 64% and 98% depending on the severity of renal insufficiency and presence of hypertension. Significant proteinuria may be an indicator of underlying renal insufficiency. Management of pregnant women with underlying renal disease should ideally entail a multidisciplinary approach at a tertiary center and include a maternal-fetal medicine specialist and a nephrologist. Such women should receive counseling regarding the pregnancy outcomes in association with maternal chronic renal disease and the effect of pregnancy on renal function, especially within the ensuing 5 years postpartum. These women will require frequent visits and monitoring of renal function during pregnancy. Women whose renal disease is further complicated by hypertension should be counseled regarding the increased risk of adverse outcome and need for blood pressure control. Some antihypertensives, especially angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, should be avoided during pregnancy, if possible, because of the potential for both teratogenic (hypocalvaria) and fetal effects (renal failure, oliguria, and demise).

Abstract
Without strict glycemic control, diabetic pregnancies are frequently complicated by spontaneous abortion, stillbirth, or congenital malformation. Retrospective studies have been largely reassuring that pregnancy does not accelerate morbid outcomes in women with diabetic vascular disease. Improved outcomes of high-risk pregnancy in women with pregestational, type 1, or type 2 diabetes mellitus remain challenging, depending on a comprehensive and multidisciplinary team approach and extensive preconception counseling.

Abstract
OBJECTIVE The aim of this study is to give the results of our experience about pregnancies among the renal transplantation patients and to assess the impact of the pregnancy on renal graft function. PATIENTS AND METHODS Twenty pregnancies from 17 renal transplant recipients were analysed and long-term outcome of the renal graft was studied. We analysed the outcomes from clinical and biological data before, during and after pregnancy. RESULTS Mean patient age was 30.3+/-3.5 years and meantime between transplantation and the onset of pregnancy was 62.4+/-34.5 months. There was no significant difference between the biological data before and after pregnancy. We did not observe any acute rejection. The mean maternal complications were preeclampsia in 35%, low birth weight in 39%, prematurity in 45% and cesarean sections in 55%. There is no impact of the pregnancy on the renal graft during the follow-up (3 years). The follow-up revealed 2 cases of chronic rejection. DISCUSSION AND CONCLUSION A multi-disciplinary approach of pregnancy in renal recipients and an interval of 2 years after kidney transplantation are necessary. There are more complications during pregnancy without increased risks of graft lose.

Abstract
Pregnancy results in physiologic changes in almost all organ systems in the body mediated mainly by female sex hormones. Physiologic changes of pregnancy influence the dental management of women during pregnancy. Understanding these normal changes is essential for providing quality care for pregnant women. This review article briefly discusses the cardiovascular, respiratory, gastrointestinal, urogenital, endocrine, and oral physiologic changes that occur during normal gestation. A summary of current scientific knowledge of ionizing radiation is presented. Information about the compatibility, complications, and excretion of the common drugs during pregnancy is provided. Drugs and their usage during breast-feeding are also discussed. Guidelines for the management of a pregnant patient in the dental office are summarized.

Abstract
Successful pregnancy outcomes are possible after all types of solid organ transplantation and thousands of successful pregnancies in such women have been reported. As immunosuppressive medications are required to maintain adequate graft and maternal survival, major concerns are the effect of these agents on the fetus and the effect of pregnancy on the well being of mother and graft, against a background of continuing advances and modifications in immunosuppressive therapy. Women should avoid unnecessary medications during pregnancy but clinicians worry most about teratogens; agents (environmental, pharmaceuticals or other chemicals) that cause abnormal development, whether this be an overt structural birth defect or more subtle derangements of embryonic or fetal development. A concern is that any agent or combination of agents and maternal condition(s) may be teratogenic, a risk that is increased in the transplant population. The goal of immunosuppression is to ensure graft and patient survival by preventing acute rejection. Combinations of agents allow for synergistic effects while minimising drug toxicities. No specific combination has been deemed optimal and the effects of more recently available combinations require further study. Although there are known theoretical risks to mother and fetus, successful pregnancies are now the rule in transplant recipients. This is without an apparent increase in the type or incidence of malformations in the newborns, and usually with no evidence of graft dysfunction and/or irreversible deterioration either related to prepregnancy graft problems or unpredictable gestational factors. For immunosuppression, what is best for the mother and her survival should ensure the best outcome for the fetus and, although no specific malformation pattern has been reported to date, there are some interesting trends worthy of continued analyses. A balance of good maternal and graft outcome with the lowest risk of fetal toxicity must be the goal of management.
