Dual Advanced Therapies and Novel Pharmacotherapies for Moderately to Severely Active Crohn's Disease.

Gastroenterol Clin North Am 2022 Jun 22;51(2):283-298. Epub 2022 Apr 22.

Division of Gastroenterology, University of California, San Diego, 9500 Gilman Drive, MC 0956, La Jolla, CA 92093-0956, USA.

Over the past 2 decades, there have been incredible advances in the pharmacotherapeutic options for the treatment of patients with moderately to severely active Crohn's disease. Despite the leaps and strides in safety, efficacy, and mechanistic specificity of treatment targets, a significant portion (up to ∼20-50%) of patients have refractory Crohn's disease ± concomitant rheumatologic disease/extraintestinal manifestations for which existing biologic and small molecule therapies are ineffective. In this review, we will explore the available evidence for the use of dual advanced therapies (combination of biologic and/or small molecule therapies) and novel pharmacotherapies in phase 2 to 3 clinical trials.

Evolution of Investigating Informed Assent Discussions about CPR in Seriously Ill Patients.

J Pain Symptom Manage 2022 Jun;63(6):e621-e632

Pulmonary, Critical Care & Sleep Medicine, Cambia Palliative Care Center of Excellence at UW Medicine (R.A.E.), University of Washington, Seattle, Seattle, Washington, USA.

Context: Outcomes after cardiopulmonary resuscitation (CPR) remain poor. We have spent 10 years investigating an "informed assent" (IA) approach to discussing CPR with chronically ill patients/families. IA is a discussion framework whereby patients extremely unlikely to benefit from CPR are informed that unless they disagree, CPR will not be performed because it will not help achieve their goals, thus removing the burden of decision-making from the patient/family, while they retain an opportunity to disagree.

The First Affiliated Hospital of Shantou University, Shantou University Medical College, Shantou, China; Department of Urology, Shenzhen Institute of Translational Medicine, Shenzhen Second People's Hospital, The First Affiliated Hospital of Shenzhen University, Shenzhen, China; Guangdong Key Laboratory of Systems Biology and Synthetic Biology for Urogenital Tumors, Shenzhen, China; International Cancer Center of Shenzhen University, Shenzhen, China; Shenzhen Institute of Synthetic Biology, Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences, Shenzhen, China. Electronic address:

Cancer represents a leading cause of death, despite the rapid progress of cancer research, leading to urgent need for accurate preclinical model to further study of tumor mechanism and accelerate translational applications. Cancer cell lines cannot fully recapitulate tumors of different patients due to the lack of tumor complexity and specification, while the high technical difficulty, long time, and substantial cost of patient-derived xenograft model makes it unable to be used extensively for all types of tumors and large-scale drug screening. Patient-derived organoids can be established rapidly with a high success rate from many tumors, and precisely replicate the key histopathological, genetic, and phenotypic features, as well as therapeutic response of patient tumor.

Ovulation triggering with hCG alone, GnRH agonist alone or in combination? A randomized controlled trial in advanced-age women undergoing IVF/ICSI cycles.

Hum Reprod 2022 May 20. Epub 2022 May 20.

Reproductive Medical Center, International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China.

Study Question: Is a dual ovulation trigger with a combination of GnRH agonist (GnRHa) and hCG superior to single hCG and/or single GnRHa trigger in improving treatment outcomes in advanced-age women (aged ≥ 35 years) undergoing IVF/ICSI treatment?

Summary Answer: Co-administration of GnRHa and hCG as a dual trigger increases the number of good-quality embryos but it is not associated with a higher number of oocytes retrieved, compared with single hCG or GnRHa trigger.

What Is Known Already: Many studies have demonstrated that a dual trigger has positive impact on oocyte maturation, retrieval rate and pregnancy rate without increasing the risk of ovarian hyperstimulation syndrome (OHSS) in some groups of IVF patients, when compared with single hCG trigger. Few studies have however been conducted to compare a dual trigger with a single GnRHa trigger, and insufficient evidence exists to support which trigger can achieve the best outcomes in IVF patients aged ≥35 years.
