Traumatic spinal cord injury in West Virginia: Disparities by insurance and discharge disposition from an acute care hospital

Context: Medicaid has been linked to worse outcomes in a variety of diagnoses such as lung cancer, uterine cancer, and cardiac valve procedures. It has furthermore been linked to the reduced health-related quality of life outcomes after traumatic injuries when compared to other insurance groups. In spinal cord injury (SCI), the care provided in the subacute setting may vary based upon payor status, which may have implications on outcomes and cost of care.

Design: A retrospective review utilizing the institutional trauma databank was performed for all adult patients with spinal cord injury since 2009. Pediatric patients were excluded. Insurance type, race, length of stay, discharge status (alive/dead), discharge disposition, injury severity score (ISS), and hospital charges billed were recorded.

Results: Two hundred patients were identified. Overall 27.5% of patients with SCI during the period of our review were Medicaid beneficiaries. ISS was similar between Medicaid and non-Medicaid patients, but the Medicaid beneficiaries were younger (37 vs 50 years of age; P?<?.001). Medicaid beneficiaries had a significantly longer length of stay (20.9 days; P?<?.001) when compared to all other patients. They furthermore were more likely to be discharged home or to a skilled nursing facility rather than an acute rehabilitation center. Inpatient charges billed for Medicaid beneficiaries were significantly higher than those of non-Medicaid patients (203,264 USD vs 140,114 USD; P?=?.015), likely reflecting the increased length of stay while awaiting appropriate disposition.

Conclusion: Medicaid patients with SCI in West Virginia had a longer hospital stay, higher charges billed, and were more likely to be discharged home or to a skilled nursing facility rather than an acute rehabilitation center, when compared to non-Medicaid patients. The lack of availability of rehabilitation facilities for Medicaid beneficiaries likely explains this difference.     

The effects of pentoxifylline on liver regeneration after portal vein ligation in rats.

AIM: To determine the effects of pentoxifylline, a methyl xanthine derivative on hepatic cell production of uninterferred lobe after portal vein branch ligation. METHODS: Sixty-six rats were randomly allocated into 9 groups with 8 rats in PVL groups and 6 rats in sham operation groups. The portal branches of the median and the lateral liver lobes, corresponding to approximately 70% of the liver volume were ligated in the PVL groups. The control group received 0.9% NaCl solution. The rats in the treatment groups received pentoxifylline at the dose of 50 mg/kg/dy. After 1, 2, 4 days of portal vein ligation in both PVL and PVNL lobes the levels of adenine nucleotides were determined and flowcytometric analysis of cell cycles were performed. RESULTS: On the first day of portal branch ligation energy charge was significantly lower, in pentoxifylline treated group comparing to pentoxifylline untreated group, both in PVL and PVNL lobes (P<0.05). Proliferative indexes were 0.38 and 0.29 in pentoxifylline treated and pentoxifylline untreated PVNL lobes respectively (P<0.05). CONCLUSION: Pentoxifylline treatment resulted in an increase of percentage of calls entering mitosis phase on the first day after PVL, somehow accelerating the regeneration process.     

Pentraxin 3 concentrations of the mothers with preterm premature rupture of membranes and their neonates,and early neonatal outcome

Background: Pentraxin 3 (PTX3) is an acute phase reactant which has been used to detect intra-amniotic infections (IAI) in pregnancy, but the prognostic value of PTX3 concentrations on neonates has not been studied. We aimed to investigate the relationship between maternal PTX3–neonatal PTX3 concentrations and early neonatal outcome.

Methods: The mothers diagnosed with preterm prelabor rupture of membranes (PPROM) (n?=?28) and their preterm infants (n?=?28) were included in the study. PTX3 concentrations were studied in plasma in the maternal peripheral blood and umbilical/peripheral vein in the neonates. The relationship between the mPTX3–nPTX3 concentrations and neonatal outcome were investigated using non-parametric tests and binary logistic regression analysis.

Results: The mean mPTX3 concentration was 10.35?±?7.82?μg/L. Ten (35.7%) of all mothers were within the normal range and 18 (64.3%) in high percentile (≥97.5 percentile). There was no relation between mPTX3 concentrations and clinical or histologic chorioamnionitis, latency of PPROM, and early neonatal outcome. Mean nPTX3 concentrations was 9.18?±?7.83?μg/L and high nPTX3 concentrations were detected in five (17.8%) neonates. nPTX3 concentrations were inversely correlated with gestational age and correlated with rate of intraventricular hemorrhage (IVH) and mortality. Neonates with high nPTX3 concentrations also have lowered APGAR scores, increased rate of respiratory distress syndrome, clinical sepsis, IVH, necrotizing enterocolitis and prolonged NICU stay.

Conclusion: High PTX3 concentrations of the newborns are associated with some worsened early neonatal outcome including lower gestational age at delivery, increased rate of IVH and mortality. Maternal PTX3 concentrations are not an adequate marker in defining clinical or histologic chorioamnionitis and early neonatal outcome.     

Seroprevalence of tetanus immunity among noninsulin-dependent diabetes mellitus patients

Tetanus is a preventable disease that continues to affect people in both developing and developed countries. The aim of the present study was to evaluate the immunity profile to tetanus in patients with Type II diabetes mellitus (DM) and to compare them with healthy controls. The tetanus antitoxin levels in 310 diabetic patients (104 males and 206 females) and in 200 healthy controls (72 males and 128 females) were measured by ELISA (Virotech, Germany). The mean antitoxin concentration in patient and control groups were 0.8238+/-1.61 and 0.9978+/-1.49 IU/ml, respectively. There was a statistically significant difference between the two groups (z=-3.520, P=.0001 and odds ratio was 2.367). There was a definitive inverse correlation between the duration of diabetes and tetanus antibody titers (Spearman's correlation analysis, r=-.155, P=.006). A gender-dependent difference in the susceptibility to tetanus was present in the diabetic group with antibody titers being significantly higher in males compared with females (z=-2.267, P=.023). For both of control (chi(2)=20.207, P=.003) and patient (chi(2)=43.532, P=.0001) groups, there was a significant inverse correlation between the tetanus immunity levels and age. Statistically, a significant drop in antibody titers of both groups was found as the period past from the last immunization increased (Pearson correlation analysis: for patient group r=-.364, P=.0001; for control group r=-.143, P=.044). The tetanus antitoxin levels were significantly increased in individuals who had primary immunization during childhood (for patient group chi(2)=17.191, P=.0001; for control group chi(2)=9.911, P=.007). A significant reduction in the level of antitoxin immunity to tetanus in association with an increased susceptibility to infections in patients with diabetes may implicate the need for improving vaccination rates in this patient group.     

Evaluation of salivary total oxidant-antioxidant status and DNA damage of children undergoing fixed orthodontic therapy

Objective:To determine the total oxidant status (TOS), total antioxidant status (TAS), and the 8-hydroxy-2′-deoxyguanosine (8-OHdG) levels and their interrelationship in the saliva of children undergoing fixed orthodontic therapy.Materials and Methods:Thirty children were randomly divided into three groups. The attachments were bonded to all of the teeth using three different orthodontic composites: Transbond XT, Kurasper F, and GrenGloo. The salivary levels of TOS, TAS, and 8-OHdG were determined three times, as follows: before treatment (T₁) and at 1 month (T₂) and 3 months (T₃) following appliance placement. All data were statistically analyzed.Results:There were no significant differences in TOS, TAS, and 8-OHdG within the same time periods among the three different orthodontic composites (P > .05). TAS in all composite groups decreased over time. These decreases were found to be significant for Kurasper F and GrenGloo at the T₁–T₃ and T₂–T₃ time periods (P < .05). In all composite groups 8-OHdG decreased between T₁ and T₂ (P < .05). However, 8-OHdG in all composite groups increased from T₂ to T₃. These differences in 8-OHdG were significant in Kurasper F and GrenGloo (P < .05).Conclusions:Fixed orthodontic appliances bonded with the tested composites did not increase the cytotoxicity markers in saliva.
