Pain and its impact on inpatient rehabilitation for acute traumatic spinal cord injury: analysis of observational data collected in the SCIRehab study.

To describe pain during inpatient rehabilitation and its impact on delivery of inpatient rehabilitation services for persons with spinal cord injury (SCI).



Prospective observational study and retrospective chart review.



Six inpatient rehabilitation facilities participating in the SCIRehab Study.



Patients (N=1357) receiving initial rehabilitation after traumatic SCI, for whom pain data were available.



Not applicable.



Self-reported rating of pain intensity (0-10), pain locations, and treatment time by various rehabilitation disciplines.



The vast majority of patients (97%) reported pain at least once during the rehabilitation stay, with an average pain intensity ± SD of 4.9 ± 2.4. Average pain intensity over the stay was severe (rated 7-10) for 30% of patients, moderate (4-6) for 42%, and mild (1-3) for 25%. Pain prevalence at admission was greater than at discharge (87% vs 74%), as was pain intensity (6.0 vs 4.6). Most (79%) of the 177 participants who did not have pain at admission reported pain at least once later in the rehabilitation stay, but their average high pain intensity over the stay was lower than that of the full sample (1.9 vs 4.9). Nearly half (47%) of patients reported pain at ≥ 3 locations during the stay, with the back, neck, and shoulder commonly reported. Patients with severe pain spent fewer days in rehabilitation, received less rehabilitation treatment time (hours per week and total hours), and had more treatment sessions altered in objective or content because of pain than those with lower pain levels.



Pain is a common problem for persons receiving inpatient rehabilitation for traumatic SCI and adversely impacts delivery of therapy services.
Epidemiology and Mechanisms of De Novo and Persistent Hypertension in the Postpartum Period.

The pathophysiology of hypertension in the immediate postpartum period is unclear.



We studied 988 consecutive women admitted to a tertiary medical center for cesarean section of a singleton pregnancy. The angiogenic factors soluble fms-like tyrosine kinase 1 and placental growth factor, both biomarkers associated with preeclampsia, were measured on antepartum blood samples. We then performed multivariable analyses to determine factors associated with the risk of developing postpartum hypertension. Of the 988 women, 184 women (18.6%) developed postpartum hypertension. Of the 184 women, 77 developed de novo hypertension in the postpartum period, and the remainder had a hypertensive disorder of pregnancy in the antepartum period. A higher body mass index and history of diabetes mellitus were associated with the development of postpartum hypertension. The antepartum ratio of soluble fms-like tyrosine kinase 1 to placental growth factor positively correlated with blood pressures in the postpartum period (highest postpartum systolic blood pressure [r=0.29, P<0.001] and diastolic blood pressure [r=0.28, P<0.001]). Moreover, the highest tertile of the antepartum ratio of soluble fms-like tyrosine kinase 1 to placental growth factor was independently associated with postpartum hypertension (de novo hypertensive group: odds ratio, 2.25; 95% confidence interval, 1.19-4.25; P=0.01; in the persistent hypertensive group: odds ratio, 2.61; 95% confidence interval, 1.12-6.05; P=0.02) in multivariable analysis. Women developing postpartum hypertension had longer hospitalizations than those who remained normotensive (6.5±3.5 versus 5.7±3.4 days; P<0.001).



Hypertension in the postpartum period is relatively common and is associated with prolonged hospitalization. Women with postpartum hypertension have clinical risk factors and an antepartum plasma angiogenic profile similar to those found in women with preeclampsia. These data suggest that women with postpartum hypertension may represent a group of women with subclinical or unresolved preeclampsia.
Assessment of Worldwide Acute Kidney Injury, Renal Angina and Epidemiology in Critically Ill Children (AWARE): study protocol for a prospective observational study

Acute kidney injury (AKI) is associated with poor outcome in critically ill children. While data extracted from retrospective study of pediatric populations demonstrate a high incidence of AKI, the literature lacks focused and comprehensive multicenter studies describing AKI risk factors, epidemiology, and outcome. Additionally, very few pediatric studies have examined novel urinary biomarkers outside of the cardiopulmonary bypass population.



This is a prospective observational study. We anticipate collecting data on over 5000 critically ill children admitted to 31 pediatric intensive care units (PICUs) across the world during the calendar year of 2014. Data will be collected for seven days on all children older than 90 days and younger than 25 years without baseline stage 5 chronic kidney disease, chronic renal replacement therapy, and outside of 90 days of a kidney transplant or from surgical correction of congenital heart disease. Data to be collected includes demographic information, admission diagnoses and co-morbidities, and details on fluid and vasoactive resuscitation used. The renal angina index will be calculated integrating risk factors and early changes in serum creatinine and fluid overload. On days 2-7, all hemodynamic and pertinent laboratory values will be captured focusing on AKI pertinent values. Daily calculated values will include % fluid overload, fluid corrected creatinine, and KDIGO AKI stage. Urine will be captured twice daily for biomarker analysis on Days 0-3 of admission. Biomarkers to be measured include neutrophil gelatinase lipocalin (NGAL), kidney injury molecule-1 (KIM-1), liver-type fatty acid binding protein (l-FABP), and interleukin-18 (IL-18). The primary outcome to be quantified is incidence rate of severe AKI on Day 3 (Day 3-AKI). Prediction of Day 3-AKI by the RAI and after incorporation of biomarkers with RAI will be analyzed.



The Assessment of Worldwide Acute Kidney Injury, Renal Angina and Epidemiology (AWARE) study, creates the first prospective international pediatric all cause AKI data warehouse and biologic sample repository, providing a broad and invaluable resource for critical care nephrologists seeking to study risk factors, prediction, identification, and treatment options for a disease syndrome with high associated morbidity affecting a significant proportion of hospitalized children.
Aldehyde dehydrogenase 1 (ALDH1) expression is an independent prognostic factor in triple negative breast cancer (TNBC)

Triple negative breast cancer (TNBC) is a subset of breast cancer that is highly aggressive and has a poor prognosis. Meanwhile, cancer stem cells (CSCs) are also characterized by a strong tumorigenic potential, which might be partly responsible for the aggressive behavior of TNBC. We previously showed that CSCs are enriched in TNBC cell lines and tissues. Further experiments in animal models revealed higher tumorigenicity of CSCs sorted from TNBC cell lines. In this study, we aimed to determine the clinical relationship between CSCs and TNBC by exploring the expression of aldehyde dehydrogenase 1 (ALDH1), which is a putative marker of breast CSCs, in TNBC tissues.ALDH1 levels in paraffin-embedded tumor tissues from 158 TNBC patients were evaluated by immunohistochemistry staining using an ALDH1A1 primary antibody. Staining evaluation was performed independently by two pathologists, and the expression level of ALDH1 was evaluated in terms of the percentage and intensity of positive cells. The association of immunohistochemistry staining of ALDH1 expression with clinical parameters was also analyzed.ALDH1 expression in tumor cells was observed in 88 out of 158 cases (55.7%). Analysis of clinicopathological parameters showed that the immunohistochemistry staining of ALDH1 was significantly correlated with tumor size (P = 0.02) and stage (P = 0.04). Survival analysis in patients with ALDH1 expression demonstrated shorter relapse-free survival (RFS) and overall survival (OS) times (P = 0.01; P = 0.001). Moreover, Cox multivariate analysis revealed that ALDH1 expression was an independent prognostic indicator of RFS and OS (P = 0.04; P = 0.04).Immunohistochemistry staining of ALDH1 in tumor cells is an independent prognostic indicator of RFS and OS in TNBC patients.
Faecal calprotectin: a noninvasive diagnostic tool and marker of severity in pouchitis.

In pouchitis, the mucosa is infiltrated by activated polymorphonuclear neutrophils capable of producing calprotectin, a stable antimicrobial myelomonocytic protein.



The aim is to assess the ability of faecal calprotectin to differentiate between inflamed and noninflamed ileal pouches, and to correlate this with inflammation severity using the newly developed Objective Pouchitis Score.



Fifty-four stool samples were collected from patients who had undergone restorative proctocolectomy; 46 from patients with ulcerative colitis and eight from those with familial adenomatous polyposis coli. Faecal calprotectin concentrations were determined by quantitative enzyme-linked immunosorbant assay.



Of the ulcerative colitis patients, six were diagnosed with pouchitis and pre-pouch ileitis (median faecal calprotectin: 865 microg/g, with a range of 95-2350 microg/g); 13 had pouchitis alone (145, 33-3350 microg/g) and 27 were uninflamed (56, 4-705 microg/g). Of the familial adenomatous polyposis patients, one had pouchitis and pre-pouch ileitis (305 microg/g), and seven had noninflamed pouches (9, 6-26 microg/g). Stool samples obtained from pouchitis patients had significantly higher calprotectin concentrations compared with those obtained from uninflamed pouches (Mann-Whitney: P<0.0001). Faecal calprotectin concentrations correlated closely with the Objective Pouchitis Score, the Pouch Disease Activity Index and endoscopic and histological inflammatory scores (Spearman rank test: P values <0.0001). Using a faecal calprotectin threshold of >or=92.5 microg/g to define a positive result, Receiver Operating Characteristic analysis demonstrated a sensitivity of 90% and a specificity of 76.5%.



Faecal calprotectin measurement is a useful noninvasive tool in the diagnosis of acutely inflamed ileal pouches and correlates well with the severity of pouchitis.
Sonographic visualization and ultrasound-guided block of the third occipital nerve: prospective for a new method to diagnose C2-C3 zygapophysial joint pain.

Chronic neck pain after whiplash injury is caused by cervical zygapophysial joints in 50% of patients. Diagnostic blocks of nerves supplying the joints are performed using fluoroscopy. The authors' hypothesis was that the third occipital nerve can be visualized and blocked with use of an ultrasound-guided technique.



In 14 volunteers, the authors placed a needle ultrasound-guided to the third occipital nerve on both sides of the neck. They punctured caudal and perpendicular to the 14-MHz transducer. In 11 volunteers, 0.9 ml of either local anesthetic or normal saline was applied in a randomized, double-blind, crossover manner. Anesthesia was controlled in the corresponding skin area by pinprick and cold testing. The position of the needle was controlled by fluoroscopy.



The third occipital nerve could be visualized in all subjects and showed a median diameter of 2.0 mm. Anesthesia was missing after local anesthetic in only one case. There was neither anesthesia nor hyposensitivity after any of the saline injections. The C2-C3 joint, in a transversal plane visualized as a convex density, was identified correctly by ultrasound in 27 of 28 cases, and 23 needles were placed correctly into the target zone.



The third occipital nerve can be visualized and blocked with use of an ultrasound-guided technique. The needles were positioned accurately in 82% of cases as confirmed by fluoroscopy; the nerve was blocked in 90% of cases. Because ultrasound is the only available technique today to visualize this nerve, it seems to be a promising new method for block guidance instead of fluoroscopy.
Nebivolol compared with metoprolol for erectile function in males undergoing coronary artery bypass graft

The aim of this study was to evaluate erectile function in males undergoing coronary artery bypass graft (CABG) while on two different adrenoceptor beta-blocker regimens, namely nebivolol and metoprolol. We hypothesize that the negative effects of cardiopulmonary bypass on erectile function may be possibly attenuated by preferring a vasodilating selective β1-blocker, nebivolol, to metoprolol as an anti-ischemic and antiarrhythmic agent in males undergoing CABG.



This randomized, double-blind, prospective clinical study was conducted in patients scheduled for CABG surgery between February 2012 and June 2014. A total of 60 consecutive patients who met inclusion criteria were randomized and divided into the following two groups: N group, which received 5 mg of nebivolol orally for 2 weeks before surgery plus 12 weeks after surgery or M group, which received 50 mg of metoprolol orally for the same period. All patients were evaluated by the erectile function domain of the International Index of Erectile Function-5 (IIEF-5) at the time of admission (before starting the beta-blocker) and 3 months after surgery.



In the metoprolol group, the mean IIEF-5 score decreased significantly from a baseline of 15.2±5.8 to 12.9±5.8 (p<0.001), but in the nebivolol group, this difference was not significant (from a baseline 12.9±5.5 to 12.4±5.5, p=0.053). In all patients, the mean IIEF-5 score decreased significantly from a baseline of 14.0±5.7 to 12.6±5.6 (p<0.001).



Although erectile function in males undergoing CABG surgery decreases when metoprolol is used, nebivolol exerts protective effects on erectile function against the disruptive effects of cardiopulmonary bypass in patients undergoing CABG.
Alexithymia and impaired facial affect recognition in multiple sclerosis

Despite the high relevance of emotion processing for social functioning, the study of the impairment of facial affect in multiple sclerosis (MS) has received little attention. Previous research reported evidence for emotion processing deficits but the nature and extent are not fully explained. Thirty-five MS patients underwent dedicated neuropsychological assessment of emotion processing using two facial affect recognition tasks and self-report measures of alexithymia. For comparison, healthy participants served as controls. Relative to healthy controls, MS patients were impaired in facial affect recognition on four of the six Ekman basic emotions, except happiness and disgust. The MS patients were more alexithymic than the healthy controls. These data provide evidence for deficits in the recognition of emotional face expressions and emotional introspection.
Effects of inulin supplementation on selected faecal characteristics and health of neonatal Saanen kids sucking milk from their dams.

Fifty newborn Saanen kids were used to study the effects of inulin supplementation on faecal score, faecal pH, selected faecal bacterial population, BW, body temperature, haematological traits, selected health parameters and the incidence of diarrhoea. Kids were sorted by parity of their dams and multiple birth (twin or triplet) and assigned to one of the two groups (control: CG, and experimental: EG) at birth. Each group consisted of 25 kids. The groups were similar with regard to sex and birth weight. All kids were fed colostrum for the first 3 days after birth, and then the kids in EG were adapted to inulin supplementation by an increased dosage from day 4 to 7. Each kid in EG was supplemented with 0.2 g, 0.3 g, 0.4 g, 0.5 g and 0.6 g inulin on day 4, 5, 6, 7 and from day 8 to 28, respectively, whereas the kids in CG did not receive inulin. Faecal score and faecal bacterial population were not affected by inulin supplementation (P > 0.05). There were differences in faecal pH on day 14 (P = 0.01) and 28 (P<0.05), whereas no difference in faecal pH on day 21 (P > 0.05) was detected between groups. No differences (P > 0.05) in BW and haematological traits were found between groups. Body temperature did not differ on day 14 and 21 (P > 0.05), whereas there was a difference in body temperature on day 28 (P = 0.01) between groups. The numbers of kids with pneumonia and kids treated for pneumonia and diarrhoea were similar for CG and EG. Kid losses during the study were the same for CG and EG. The incidence of diarrhoea was not affected by inulin supplementation (P > 0.05). Inulin supplemented to kids did not adversely affect faecal score. The effect of inulin on faecal pH was not consistent. The results of our study suggested that daily dose (0.6 g) of inulin might not be enough to observe effects of it. Our data will be useful to determine the dose and timing of inulin supplementation in future studies investigating the effects of inulin on the parameters associated with performance and health status in kids and other young ruminants.
Baseline clinical status as a predictor of methylprednisolone response in multiple sclerosis relapses.

To date, there are no available factors to predict the outcome after multiple sclerosis relapse.



To investigate factors that may be useful for predicting response to methylprednisolone treatment, following a relapse of multiple sclerosis (MS).



The study included 48 MS patients enrolled in a double-blind multicenter trial to receive intravenous versus oral high-dose methylprednisolone treatment. Associations were sought between the disability status prior to relapse and the relapse severity, determined by changes in the Expanded Disability Status Scale (EDSS) score, as well as the improvements after treatment. We also analyzed the relationships between the number of magnetic resonance imaging (MRI) gadolinium-enhancing lesions (Gd+) and improvement.



A higher EDSS score before relapse was associated with more severe relapses (p = 0.04) and less marked improvement (odds ratio (OR) 1.8; 95% CI (1.2-2.2); p = 0.05) after methylprednisolone treatment. Relapse severity (p = 0.29) and the number of Gd+ lesions at relapse (p = 0.41) were not related with improvement.



Clinical baseline status prior to MS relapse is a predictor of response to methylprednisolone treatment.
Nuclear MTA1 overexpression is associated with aggressive prostate cancer, recurrence and metastasis in African Americans

Metastasis-associated protein 1 (MTA1), a negative epigenetic modifier, plays a critical role in prostate cancer (PCa) progression. We hypothesized that MTA1 overexpression in primary tumor tissues can predict PCa aggressiveness and metastasis. Immunohistochemical staining of MTA1 was done on archival PCa specimens from University of Mississippi Medical Center and University of Iowa. We found that nuclear MTA1 overexpression was positively correlated with the severity of disease progression reaching its highest levels in metastatic PCa. Nuclear MTA1 overexpression was significantly associated with Gleason > 7 tumors in African Americans but not in Caucasians. It was also a predictor of recurrent disease. We concluded that MTA1 nuclear overexpression may be a prognostic indicator and a future therapeutic target for aggressive PCa in African American men. Our findings may be useful for categorizing African American patients with a higher probability of recurrent disease and metastasis from those who are likely to remain metastasis-free.
Quality of life in patients with ulcerative colitis.

Patients with inflammatory bowel disease (IBD) have to live with the perspective of a potential disability, which may lead in time to impaired quality of life (QoL). In order to fully understand the impact of IBD on patients and their careers we need to quantify the QoL.



To evaluate HRQol in ulcerative colitis patients as opposed to the general population and to identify the significant changes of HRQoL in accordance with the specific progression of UC.



The prospective study (January 2010 - December 2012), included 105 patients with ulcerative colitis (UC). Disease activity was quantified by means of the Truelove and Witts score (mild, moderate and severe). All patients were administered a self-completed IBD questionnaire (IBDQ). Lower scores were related to a worse QoL. Statistical analysis was performed and di fferences were considered significant when p < or = 0.05.



Ninety-one percent (91%) were admitted with a flare, while they were asked to fill in the IBDQ. Proctitis was met in 2.94% of the cases, left-sided colitis in 71.1% and pancolitis in 26%. There were 32 patients with mild activity, 62 with moderate activity and only 3 with severe activity. The range score for QoL was 90-180. In proctitis: 80-190, in left-side colitis: 120-200, in pancolitis: 70-160 (p>0.05). The patients with severe form had a lower score (50-140) than patients in remission (130-180) (p<0.01).



Patients with UC have significantly influenced the QoL as compared to the general population. We found no significant differences regarding the extension of the lesions. The severity of the flare had a significant impact on the QoL.
Carbon monoxide feedback in a motivational decision support system for nicotine dependence among smokers with severe mental illnesses.

Health concerns are common reasons for wanting to quit smoking among smokers with mental illnesses. Motivational interventions have used feedback from a carbon monoxide monitor to increase awareness of health concerns, but this device is not commonly available. Whether brief motivational interventions can be effective without this feedback is unknown. Using a randomized controlled trial, this study tested the effect of carbon monoxide feedback within a brief, multi-component, computerized motivational intervention among 124 smokers with schizophrenia or mood disorders. The main outcome was initiating cessation treatment over two months. Although participants in the carbon monoxide group increased their knowledge about the carbon monoxide, (χ(2)=6.97, df=1, p=.008), the main and secondary outcomes did not differ significantly between groups. Overall, 32% of participants initiated treatment. This study suggests that a computerized motivational decision support system can lead users to initiate cessation treatment, and that carbon monoxide feedback is not a necessary component.
In vivo effects of mesalazine or E. coli Nissle 1917 on microsatellite instability in ulcerative colitis.

Microsatellite instability (MSI) occurs in chronically inflamed colorectal tissue and may evolve to colitis-associated cancer. In vitro data suggest that mesalazine (5-ASA) improves MSI.



To analyse the changes in MSI in 156 distal colonic biopsies of 39 patients with ulcerative colitis that had been treated within a randomized, double-blind trial comparing 5-ASA with E. coli Nissle (EcN).



Two biopsies had been collected before and after 1 year of treatment. MSI testing was performed using a panel of eight markers, including 3 dinucleotide and 5 mononucleotide repeats.



No MSI was observed with any of the mono-repeats, and among dinucleotide repeats, only D5S346 (maps to APC) and D17S250 (p53) were consistently informative. Overall, 31/156 (20%) biopsies displayed MSI. After 1 year, 3/11 patients displayed MSI improvement [change to microsatellite stability (MSS); 1 on 5-ASA, 2 on EcN] at D5S346 and 4/11 showed MSI worsening (change from MSS to MSI; all 5-ASA). For D17S250, the corresponding data were for 3/9 patients (2 on 5-ASA, 1 on EcN) and 2/9 (both on 5-ASA), respectively.



In the set of biopsies taken from patients treated with 1.5 g 5-ASA for 1 year, there was no improvement in the prevalence of MSI in the distal colon.
