A new technique to preserve the uterus in patients with placenta accreta spectrum disorders

BACKGROUND

Placenta accreta spectrum disorders are associated with substantial maternal morbidity and mortality. Despite a preoperative diagnosis, the rate of complications remains high, and the condition is generally associated with the need for a hysterectomy.

OBJECTIVE

This study aimed to evaluate the outcomes of a new uterine-preserving technique (called the combined approach, including surgical hemostasis, bilateral ligation of the descending branches of the uterine arteries, and hemostatic external supraplacental stitch with the use of the Zhukovsky double-balloon tamponade in patients with placenta accreta spectrum disorders) during cesarean delivery in women with placenta accreta spectrum disorders vs the surgical technique used until 2014.

STUDY DESIGN

This retrospective cohort study included 147 patients with placenta accreta spectrum disorders who were divided into 2 groups: the study group (n=95) is to undergo cesarean delivery using the combined approach, and the control group (n=52) is to undergo the surgical technique used until 2014, which included bilateral uterine artery ligation, which is the transfusion of plasma, red blood cells, platelets, and protease inhibitors.

RESULTS

The volume of blood loss was 1.5-fold lower (P=.0010), the number of blood transfusions was 5.1-fold lower (P=.026), and the rate of bladder injuries was 19-fold lower (P=.012) in the study group than that in the control group. The duration of hospital stay after delivery was 4 days lesser (P=.001) and the number of hysterectomies was 4.5-fold lower in the study group than in the control group (P=.023). The study groups did not differ in terms of placenta accreta spectrum type.

CONCLUSION

The combined approach during cesarean delivery proved to be more effective than the surgical technique used until 2014 in reducing the number of hysterectomies, blood loss volume, number of blood transfusions, and duration of hospital stay in patients with placenta accreta spectrum disorders.

Iron stores in steady-state sickle cell disease children accessing care at a sickle cell disease clinic in Kumasi, Ghana: A cross-sectional study

Background and Aims

Children with sickle cell disease (SCD) have an increased risk of multiple hemotransfusions and this can predispose them to elevated iron stores. The objectives of the study were to determine the extent of elevated iron stores and the associated risk factors in a population of steady-state SCD children in Ghana.

Methods

This cross-sectional study was conducted at the pediatric sickle cell clinic at the Komfo Anokye Teaching Hospital. Complete blood count and serum ferritin assay were performed for (n = 178) steady-state SCD children. Descriptive and multivariate logistic regression analysis were performed. Elevated iron stores were defined as serum ferritin levels >300 ng/ml. Statistical significance was considered at p < 0.05.

Results

The mean (standard deviation) age of the participants was 9.61 (±4.34) years, and 51% of them were males. About 17% of SCD children had elevated iron stores and receiving at least three hemotransfusions during the last 12 months was strongly associated with elevated iron stores (p < 0.001). History of chronic hemotransfusion increased the odds of having elevated iron store (adjusted odds ratio [aOR] = 11.41; 95% confidence interval [CI] = 3.11-30.85; p < 0.001) but SCD patients on hydroxyurea treatment had reduced-odds of having elevated iron stores (aOR = 0.18; 95% CI = 0.06-0.602; p = 0.006). Moreover, red blood cell (Coef. = -0.84; 95% CI = -0.37, -1.32; p = 0.001), hemoglobin (Coef. = -0.83; 95% CI = -0.05, -1.61; p = 0.04), hematocrit (Coef. = -0.85; 95% CI = -0.08, -1.63; p = 0.03), mean cell volume (Coef. = 0.02; 95% CI = 0.01, 0.03; p = 0.001) and mean cell hemoglobin (Coef. = 0.04; 95% CI = 0.01, 0.07; p = 0.002) could significantly predict serum ferritin levels.

Conclusion

The magnitude of elevated iron stores was high among children with SCD in steady-state. Red cell indices could provide invaluable information regarding the risk of elevated iron stores. SCD children who have a history of chronic hemotransfusion or had received at least three hemotransfusions in a year should be monitored for elevated iron stores.

[Review of current issues of diagnosis and prevention of blood-borne nosocomial viral infections.]

Provision of infection security in transplantology and transfusiology is a challenging and significant problem that depends on the quality of medical donor selection and laboratory diagnosis of the blood collected. At present, a large number of blood-borne viruses are known; nevertheless, in Russia, the list of viral agents to be tested during the examination by the blood service boils down to three ones: HIV, hepatitis C and hepatitis B viruses. The review article demonstrates the need for implementation of additional laboratory tests for the agents of the priority healthcare-associated blood-borne infections (HAI) using a risk-based approach, i.e., on specified sites and in high risk groups. It presents a methodology for determination of a quantitative blood-induced infection residual risk (BIRR) index to be used while evaluating the efficiency of viral security provision in the blood service.
