Health state utilities of a population of Nigerian hypertensive patients

<p>Abstract</p> <p>Background</p> <p>Establishment of the health impact of hypertension on quality of life of Nigerians is a step towards controlling the disease. The study aimed to provide a Nigerian specific reference list of utility scores of hypertensive patients with various interacting conditions.</p> <p>Findings</p> <p>An interviewer-based, cross-sectional study was conducted using hypertensive patients in two purposively selected tertiary hospitals located in South-Eastern Nigeria. Health Utility Index Mark 3 (HUI3) was used.</p> <p>A total of 384 participants with either hypertension alone or with hypertension-associated complications were interviewed in the two tertiary hospitals.</p> <p>The overall mean utility score was 0.35 +/- 0.42. Patients with hypertension alone had the highest overall mean utility score (0.57 +/- 0.29) while hypertensive patients with stroke had the lowest overall mean score (0.04 +/- 0.36). Being a male, increase in age and mean arterial blood pressure, emergency visit and loss of work due to illness were associated with significant decrease in overall utility scores.</p> <p>Conclusions</p> <p>This study presented a reference for health state utilities of a population of Nigerian hypertensive patients.</p

Laparoscopic excision of an extra-biliary gallbladder duplication cyst in a 9-month-old infant

Duplication of the gallbladder is a rare congenital anomaly of the biliary system. We herein present a case of a 9-month-old full-term female with a prenatally identified gallbladder duplication cyst managed via laparoscopic excision

CD26 inhibition enhances allogeneic donor-cell homing and engraftment after in utero hematopoietic-cell transplantation

In utero hematopoietic-cell transplantation (IUHCT) can induce donor-specific tolerance to facilitate postnatal transplantation. Induction of tolerance requires a threshold level of mixed hematopoietic chimerism. CD26 is a peptidase whose inhibition increases homing and engraftment of hematopoietic cells in postnatal transplantation. We hypothesized that CD26 inhibition would increase donor-cell homing to the fetal liver (FL) and improve allogeneic engraftment following IUHCT. To evaluate this hypothesis, B6GFP bone marrow (BM) or enriched hematopoietic stem cells (HSCs) were transplanted into allogeneic fetal mice with or without CD26 inhibition. Recipients were analyzed for FL homing and peripheral-blood chimerism from 4 to 28 weeks of life. We found that CD26 inhibition of donor cells results in (1) increased homing of allogeneic BM and HSCs to the FL, (2) an increased number of injected animals with evidence of postnatal engraftment, (3) increased donor chimerism levels following IUHCT, and (4) a competitive engraftment advantage over noninhibited congenic donor cells. This study supports CD26 inhibition as a potential method to increase the level of FL homing and engraftment following IUHCT. The resulting increased donor chimerism suggests that CD26 inhibition may in the future be used as a method of increasing donor-specific tolerance following IUHCT

A multi-institution analysis of predictors of timing of inguinal hernia repair among premature infants

Purpose Inguinal hernias are common in premature infants, but there is substantial variation with regards to timing of repair. We sought to quantify and explain this variation. Methods Cohort study of infants < 34 weeks gestation diagnosed with an inguinal hernia and discharged from one of 329 neonatal intensive units between 1998 and 2012. Multivariable logistic regression clustered by site was used to evaluate demographic, clinical, maternal, and socioeconomic variables associated with pre-discharge repair. Results A total of 8037 infants met study criteria, and 3230 (40%) received a pre-discharge repair. The frequency of pre-discharge repair varied by site from 9% to 84%, and increased over the study period from 20% in 1998 to 45% in 2012. Concurrent gastrostomy or fundoplication and lower socioeconomic status were associated with an increased odds of receiving a pre-discharge repair. Conclusion There is substantial variation with regards to the timing of repair of inguinal hernias in premature infants, with an increasing number of infants receiving repair prior to hospital discharge over time. Concurrent gastrostomy or fundoplication and socioeconomic status are associated with timing of repair
