In utero administration of hematopoietic stem cells (HSCs) has a variety of actual or potential clinical applications but is hindered by invasive, morbid administration techniques. We sought to determine whether donor HSCs could reach the fetal circulation after simple intra-amniotic delivery in a syngeneic rat model of transamniotic stem cell therapy (TRASCET).
Pregnant Lewis rat dams underwent volume-matched intra-amniotic injections in all fetuses (n=90) on gestational day 17 (E17; term=E21-22) of a suspension of commercially available syngeneic Lewis rat HSCs labeled with luciferase (n=37 fetuses) or an acellular suspension of recombinant luciferase (n=53). HSC phenotype was confirmed by flow cytometry. Fetuses were euthanized at term for screening of luciferase activity at select anatomical sites. Statistical comparisons were by Fisher's exact test.
Among survivors (47/90; 52.2%), donor HSCs were identified selectively in the placenta (p=0.003), umbilical cord (p<0.001), bone marrow (p<0.001), thymus (p=0.009), bowel (p=0.003), kidney (p=0.022), and skin (p<0.001) when compared with acellular luciferase controls.
Donor hematopoietic stem cells undergo hematogenous routing and can reach the fetal bone marrow after simple intra-amniotic delivery in a syngeneic rat model. Transamniotic stem cell therapy may become a practicable, minimally invasive strategy for the prenatal administration of these cells.

We examined whether engineered overexpression of fibroblast growth factor-2 (Fgf2) in donor mesenchymal stem cells (MSCs) could enhance spina bifida coverage induced by transamniotic stem cell therapy (TRASCET).
Pregnant Sprague-Dawley dams (n=24) exposed to retinoic acid for induction of fetal spina bifida were divided in three groups. An untreated group had no further manipulations. Two groups received volume-matched intra-amniotic injections into all fetuses (n=157) of either amniotic fluid-derived MSCs (afMSC; n=85) or afMSCs transduced with an Fgf2 transgene (Fgf2-afMSC; n=72) on gestational day 17 (term=21-22 days). Defect coverage was categorized at term by histology and pan-cytokeratin immunohistochemistry. Statistical coverage comparisons were by logistic regression.
Among 84 survivors with isolated spina bifida, 71 had definitive histology. Defect coverage rates in both the afMSC (38.5%) and Fgf2-afMSC (73.3%) groups were statistically significantly higher than in the untreated group (10%; p<0.001 for both). There was a significantly higher coverage rate in the Fgf2-afMSC group compared with the afMSC group (p=0.025).
Fgf2 overexpression in donor mesenchymal stem cells increases defect coverage rates in a rodent model of transamniotic stem cell therapy for spina bifida. Genetic engineering of donor cells is a promising strategy for the enhancement of this emerging therapy.

Ultrasound-guided (US) transversus abdominis plane (TAP) block is commonly utilized as part of a multi-modal approach for postoperative pain management. This study seeks to determine whether laparoscopic-guided TAP blocks are as effective as US-guided TAP blocks among pediatric patients.
In this prospective, randomized controlled trial, pediatric patients undergoing laparoscopic procedures were randomly assigned to one of two treatment arms US-guided TAP block (US-arm) or laparoscopic-guided TAP block (LAP-arm). Primary outcome was PACU pain scores. Secondary outcomes included PACU opioid consumption, block completion time and block accuracy.
Twenty-five patients were enrolled in each arm. In the LAP-arm, 59% of blocks were in the transversus abdominis plane compared to 74% of TAP blocks in the US-arm (p=0.18). Blocks were completed faster in the LAP-arm (2.1±1.9vs. 7.9±3.4min, p<0.001). The average highest PACU pain score was 3.4±3.1 for the LAP-arm and 4.3±3.8 for the US-arm (p=0.37). Overall PACU pain scores and opioid consumption were similar between the groups (1.2±1.3vs. 1.6±1.6, p=0.24; 2.2±5.8vs. 0.9±1.4MME, p=0.26).
Laparoscopic TAP blocks have equivalent efficacy in post-operative pain scores, narcotic use, and tissue plane accuracy as compared to US-guided TAP blocks. They are also completed faster and may result in less operating room and general anesthetic time for the pediatric patient.

Probably the interest in this topic has arisen with regard to the inclusion in the DSM-IV of the new category "Religious or Spiritual Problem" (Code V62.89). Until then, religious or spiritual issues had been viewed in the clinical practice as symptoms of some mental illnesses like, for example, the delusions with religious content typical of schizophrenics. But with the fourth edition of the aforementioned manual, there began to be an interest in the study of spirituality as it expresses a fundamental aspect of personality. In this vein, various models of integration of spirituality and psychotherapy have been formulated. Our intention is to study the problem of incommensurability as one of the epistemological and methodological problems that supposes a project of this type. We present the writings of the Desert Fathers as an explanatory model that guarantees an epistemologically legitimate integration of spiritual traditions with psychotherapeutic practice.
