Are We Ready for a Human Head Transplant? The Obstacles That Must Be Overcome

AbstractPurpose of ReviewSaving an individual ’s life by replacing his/her terminally diseased body with a healthy donor body would be an extraordinary scientific achievement. However, body-to-head transplantation (BHT) is neither a conventional proposal nor necessarily a logical “next step” in transplantation medicine. This review highli ghts the major hurdles standing in the way of performing human BHT.Recent FindingsRecent human BHT publicity was initiated by Sergio Canavero ’s TED talk “Head Transplantation: The Future Is Now” (At: and a number of public interviews promising to perform the first human case by December 2017, despite little research and public discourse on this subject. Both are necessary in the development of innovative and perhaps paradigm-shifting surgeries.SummaryRelatively little research has been conducted on BHT. This review discusses several major questions that have yet to be answered such as viability of spinal cord reconnection, immunological issues related to head-brain-body rejection, ethical and psychosocial issues posing questions regarding informed consent, and psychological consequences. The ethical, surgical, immunological, and psychosocial requisites to perform human BHT successfully are extraordinarily complex and at this time lack adequate experimental foundation.

ReyntjensAbstractThe combined transplantation of a thoracic organ and the liver is performed in patients with dual-organ failure in whom survival is not expected with single-organ transplantation alone. Although uncommonly performed, the number of combined liver-lung and liver-heart transplants is increasing. Anesthetic management of this complex procedure is challenging. Major blood loss, prolonged operation time, difficult weaning ...

The iPSCs showed a normal karyotype and exhibited the potential to differentiate into three germ layers in a teratoma assay, which is often used to assess the pluripotency of ...

We examined whether Rhy promotes this regulation in bone marrow human mesenchymal stromal cells (BM-hMSCs). Results revealed (i) Rhy modulated biological activity by regulating the mitochondria, N-methyl-D-aspartate receptor subunit, and levels of FGFβ (basic fibroblast growth factor), BDNF (brain-derived neurotrophic factor), OXTR (oxytocin receptor) and ATP (Adenosine triphosphate); (ii) Rhy altered expression level of BM-MSC proliferation/differentiation-related transcription genes; and (iii) interestingly, Rhy amplified the glycolytic flow ratio and lactate dehydrogenase activity while reducing pyruvate dehydrogen...

Bilateral renal agenesis has historically been described as “incompatible with life” as chronic anhydramnios results in pulmonary hypoplasia, leading to respiratory failure at birth. Recent reports have detailed the survival of infants with renal disease and severe oligo-/anhydramnios following prenatal serial amnioinfusions as a bridge to neonatal dialy sis with the goal of pediatric kidney transplant. Subsequently, clinical trials have proposed treating fetuses with bilateral renal agenesis with serial prenatal amnioinfusions to allow for pulmonary maturation and the potential for long-term survival.

As palliative medicine expands within the scope of care for patients with cancer, the interface between hematologic malignancies and palliative care is increasing. These patients are underrepresented compared to their solid tumor counterparts regarding palliative care consultation. A growing body of literature supports earlier palliative care for patients with hematologic malignancies. From the impact of palliative care on bone marrow transplant patients' quality of life, utility of informatics in symptom assessment, and the role of transfusions in medical decision making regarding hospice, palliative medicine providers ar...

Therapeutic yoga (TY) gently supports the body in therapeutic positions and may include relaxation breathing, comforting touch, and mindfulness meditation (MM). Evidence suggests that yoga, relaxation, and MM can help reduce anxiety, pain, nausea, and constipation. We piloted a feasibility project at a large New York teaching hospital to expand an established palliative care TY/MM program to include supportive cardiology patients. These are patients with advanced heart failure who are often awaiting (or have received) cardiac transplant, ventricular assistive devices, or total artificial heart support.

Hematopoietic stem cell transplantation (HSCT) is potentially curative for children with life-threatening conditions but can result in a high symptom burden and poor quality of life (QoL). Parents provide extensive care for their children and can experience psychological distress.

Hematopoietic cell transplant (HCT) carries a high risk of morbidity and mortality. Palliative care (PC) integration in HCT may improve patient/caregiver outcomes, however little is known about the impact of PC involvement on end-of-life care in pediatric HCT.
