The clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) system is a versatile and convenient genome-editing tool with prospects in gene therapy. This technique is based on customized site-specific nucleases with programmable guiding RNAs that cleave and introduce double-strand breaks (DSBs) at the target locus and achieve precise genome modification by triggering DNA repair mechanisms. Human hematopoietic stem/progenitor cells (HSPCs) are conventional cell targets for gene therapy in hematological diseases and have been widely used in most studies. ⋯ CRISPR/Cas9-mediated genome editing in autologous HSPCs and iPSCs is an ideal therapeutic solution for treating hereditary hematological disorders. Here, we review and summarize the latest studies about CRISPR/Cas9-mediated genome editing in patient-derived HSPCs and iPSCs to treat hereditary hematological disorders. Current challenges and prospects are also discussed.

Intracerebral haemorrhage in patients with brain metastases receiving therapeutic anticoagulation.
Venous thromboembolism is common in patients with solid malignancies and brain metastases. Whether to anticoagulate such patients is controversial given the possibility of intracerebral haemorrhage (ICH). We evaluated the added risk of ICH in patients with brain metastases receiving therapeutic anticoagulation. ⋯ Anticoagulation is associated with clinically significant ICH in patients with brain metastases, especially those with melanoma or prior ICH. The indication for anticoagulation and risk of intracerebral bleeding should be considered on an individual basis among such patients.

Clinical Outcomes of Pregnant and Postpartum Extracorporeal Membrane Oxygenation Patients.
The use of extracorporeal membrane oxygenation (ECMO) as a rescue therapy for cardiopulmonary failure is expanding in critical care medicine. In this case series, we describe the clinical outcomes of 21 consecutive pregnant or postpartum patients that required venovenous (VV) or venoarterial (VA) ECMO. Our objective was to characterize maternal and fetal survival in peripartum ECMO and better understand ECMO-related complications that occur in this unique patient population. ⋯ Survival for mother and neonate are excellent with peripartum ECMO in a high-volume ECMO center. Neonatal and maternal survival was 100% when ECMO was used in the late second or early third trimester. Based on these results, ECMO remains an important treatment option for peripartum patients with cardiopulmonary failure.

Observational Study
Patient Factors Associated with Opioid Consumption in the Month Following Major Surgery.
The aim of this study was to determine preoperative patient characteristics associated with postoperative outpatient opioid use and assess the frequency of postoperative opioid overprescribing. ⋯ In this prospective cohort of opioid-naïve patients undergoing major surgery, we found a number of characteristics associated with greater opioid use in the first month after surgery. Future studies should address the use of non-opioid medications and behavioral therapies in the perioperative period for these higher risk patients.
