Over the past decade, practice of sharing brain magnetic resonance imaging (MRI) data is increasing given significance of reproducibility and transparency in human neuroscience. Larger multimodal brain MRI databases are needed for more robust research findings considering potential possibilities of large variability in human neuroscience. There are currently more than tens of thousands of shared brain MRI datasets across multiple conditions and hundreds of neuroimaging studies using multimodality through shared brain MRI data repositories. This article critically reviews aims, procedures, and current state of brain MRI data sharing. This review focuses on projects and research findings using structural and functional MRI open databases and is further divided into T1- and diffusion-weighted images for structural MRI as well as resting-state and task-based functional MRI. The challenges and directions are finally discussed. Advances in brain MRI data sharing will lead to more rapid progression in human neuroscience by fostering effective longitudinal, multi-site, multimodal neuroimaging research.

Although prenatal and neonatal intensive care in recent years improved survival of infants, the risk of cerebral palsy (CP) in infants with perinatal asphyxia persisted. Screening criteria for risk factors of cerebral palsy and delayed development (DD) in term infants with perinatal asphyxia are required so that early diagnosis and rehabilitation and physical therapy could decrease the neurologic complications and maximize quality of life. To identify the risk factors of CP and DD in infants with perinatal asphyxia, we undertook a case-control study of 25 infants with perinatal asphyxia (5 min Apgar score below 6). At one year follow-up, 12 infants developed CP and DD and 13 control infants showed normal development. Risk factors associated with an increased risk of CP and DD were the number of abortion (p=0. 031), history of neonatal seizure (p=0.021), hypoxic ischemic encephalopathy (p=0.046), and poor response to resuscitation immediately after birth (p=0.017). In term infants with perinatal asphyxia, the risk factors of CP and DD were increased number of abortion, history of neonatal seizure, and hypoxic ischemic encephalopathy and poor response to resuscutation. Thus infants with these risk factors should be carefully followed up after hospital discharge and further extensive and prospective study in term infants with perinatal asphyxia could elucidate possible mechanisms related to cerebral palsy and delayed development.

Hyperbaric oxygen therapy (HBOT) is a noninvasive method that supplies pure oxygen under a pressure greater than normal atmospheric pressure to increase the partial pressure of oxygen in the plasma and tissue. Based on the potential mechanisms of HBOT, including neuroprotection and neurological recovery, HBOT has been suggested as a promising therapeutic option for neurological and psychiatric disorders. This review specifically focused on the clinical trials applying HBOT for psychiatric disorders published during the recent decade. We critically reviewed the efficacy and safety of HBOT in psychiatric disorders, and cautiously suggested the future directions for further research.

PURPOSE: The vancomycin dosage regimen is regularly modified according to the patient's glomerular filtration rate (GFR). In the present study, we aimed to assess the usefulness of serum cystatin C (Cys-C) concentration, compared with serum creatinine (SCr) concentration, for predicting vancomycin clearance (CLvcm) in neonates. METHODS: We retrospectively analyzed the laboratory data of 50 term neonates who were admitted to the neonatal intensive care unit and received intravenous vancomycin, and assessed the pharmacokinetic profiles. Creatinine clearance (CLcr) and GFR based on Cys-C (GFRcys-c) were estimated using the Schwartz and Larsson formulas, respectively. RESULTS: The mean CLvcm (+/-standard deviation) was 74.52+/-31.17 L/hr, the volume of distribution of vancomycin was 0.67+/-0.14 L, and vancomycin half-life was 9.16+/-17.42 hours. The SCr was 0.46+/-0.25 mg/dL and serum Cys-C was 1.43+/-0.34 mg/L. The peak and trough concentrations of vancomycin were 24.65+/-14.84 and 8.10+/-5.35 mcg/mL, respectively. The calculated GFR based on serum creatinine concentration (GFR-Cr) and GFRcys-c were 70.2+/-9.45 and 63.6+/-30.18 mL/min, respectively. The correlation constant for CLvcm and the reciprocal of Cys-C (0.479, P=0.001) was significantly higher than that for CLvcm and the reciprocal of SCr (0.286, P=0.044). GFRcys-c was strongly correlated with CLvcm (P=0.001), and the correlation constant was significantly higher than that for CLvcm and CLcr (0.496, P=0.001). Linear regression analysis showed that only GFRcys-c was independently and positively correlated with CLvcm (F=41.9, P<0.001). CONCLUSION: The use of serum Cys-C as a marker of CLvcm could be beneficial for more reliable predictions of serum vancomycin concentrations, particularly in neonates.

PURPOSE: We investigated the effects of restricted fluid in the first 7 days of life on the risk of bronchopulmonary dysplasia (BPD) or patent ductus arteriosus (PDA) in very low birth weight (VLBW) infants. METHODS: Eighty three VLBW infants who lived more than 28 days were selected. The amount of daily maintenance fluid was determined by calculation of insensible water loss (IWL) and urine output (UO). Seventy to 80 percent of calculated amount was given to the ventilated infants. Subjects were grouped into low (<25th%), moderate (25-75th%), and high (>75th%) fluid groups for the first 24 hours, 3 days and 7 days. Chi square tests analyzed proportions of subjects with or without morbidities across fluid groups. Multivariate logistic regression was used to analyze the effect of fluid intake on BPD or PDA, controlling for factors that are significantly associated with BPD or PDA by univariate analysis. RESULTS: Rates of BPD and PDA were not significantly associated with fluid groups on each time period. The result was the same after controlling for factors that are significantly associated with BPD or PDA by univariate analysis. For the first 3 and 7 days, fluid intakes were positively related with maximal weight loss, urine output and mechanical ventilation duration. CONCLUSION: In VLBW infants, when given based on needs reflected from IWL and UO versus intake, relatively low fluid intakes in the first week of life do not decrease the risk of BPD or PDA, and vice versa. We suggest that calculation of daily fluid based on IWL and UO is appropriate for VLBW infants.

Over the past decade, an increasing number of neuroimaging studies have provided insight into the neurobiological mechanisms of posttraumatic stress disorder (PSTD). In particular, molecular neuroimaging techniques have been employed in examining metabolic and neurochemical processes in PTSD. This article reviews molecular neuroimaging studies in PTSD and focuses on findings using three imaging modalities including positron emission tomography (PET), single photon emission computed tomography (SPECT), and magnetic resonance spectroscopy (MRS). Although there were some inconsistences in the findings, patients with PTSD showed altered cerebral metabolism and perfusion, receptor bindings, and metabolite profiles in the limbic regions, medial prefrontal cortex, and temporal cortex. Studies that have investigated brain correlates of treatment response are also reviewed. Lastly, the limitations of the molecular neuroimaging studies and potential future research directions are discussed.
