Background The purpose of this study was to identify incidence and survival patterns in conformational neurodegenerative disorders (CNDDs). Methods We identified 2563 reports on the incidence of eight conditions representing sporadic, acquired and genetic, protein-associated, i.e., conformational, NDD groups and age-related macular degeneration (AMD). We selected 245 papers for full-text examination and application of quality criteria. Additionally, data-collection was completed with detailed information from British, Swedish, and Spanish registries on Creutzfeldt-Jakob disease (CJD) forms, amyotrophic lateral sclerosis (ALS), and sporadic rapidly progressing neurodegenerative dementia (sRPNDd). For each condition, age-specific incidence curves, age-adjusted figures, and reported or calculated median survival were plotted and examined. Findings Based on 51 valid reported and seven new incidence data sets, nine out of eleven conditions shared specific features. Age-adjusted incidence per million person-years increased from ≤1.5 for sRPNDd, different CJD forms and Huntington's disease (HD), to 1589 and 2589 for AMD and Alzheimer's disease (AD) respectively. Age-specific profiles varied from (a) symmetrical, inverted V-shaped curves for low incidences to (b) those increasing with age for late-life sporadic CNDDs and for sRPNDd, with (c) a suggested, intermediate, non-symmetrical inverted V-shape for fronto-temporal dementia and Parkinson's disease. Frequently, peak age-specific incidences from 20–24 to ≥90 years increased with age at onset and survival. Distinct patterns were seen: for HD, with a low incidence, levelling off at middle age, and long median survival, 20 years; and for sRPNDd which displayed the lowest incidence, increasing with age, and a short median disease duration. Interpretation These results call for a unified population view of NDDs, with an age-at-onset-related pattern for acquired and sporadic CNDDs. The pattern linking age at onset to incidence magnitude and survival might be explained by differential pathophysiological mechanisms associated with specific misfolded protein deposits.

Biomarkers are critically needed for the early detection of pancreatic cancer (PC) are urgently needed. Our purpose was to identify a panel of genetic variants that, combined, can predict increased risk for early-onset PC and thereby identify individuals who should begin screening at an early age. Previously, we identified genes using a functional genomic approach that were aberrantly expressed in early pathways to PC tumorigenesis. We now report the discovery of single nucleotide polymorphisms (SNPs) in these genes associated with early age at diagnosis of PC using a two-phase study design. In silico and bioinformatics tools were used to examine functional relevance of the identified SNPs. Eight SNPs were consistently associated with age at diagnosis in the discovery phase, validation phase and pooled analysis. Further analysis of the joint effects of these 8 SNPs showed that, compared to participants carrying none of these unfavorable genotypes (median age at PC diagnosis 70 years), those carrying 1–2, 3–4, or 5 or more unfavorable genotypes had median ages at diagnosis of 64, 63, and 62 years, respectively (P = 3.0E–04). A gene-dosage effect was observed, with age at diagnosis inversely related to number of unfavorable genotypes (Ptrend = 1.0E–04). Using bioinformatics tools, we found that all of the 8 SNPs were predicted to play functional roles in the disruption of transcription factor and/or enhancer binding sites and most of them were expression quantitative trait loci (eQTL) of the target genes. The panel of genetic markers identified may serve as susceptibility markers for earlier PC diagnosis. PMID:27486767

Renal and obstetric outcomes in pregnancy after kidney transplantation in Singapore were last studied in 2002. A review of these outcomes in Singapore is now timely following advances in transplant and obstetric medicine. The aim was to evaluate the renal and obstetric outcomes in pregnancy after kidney transplantation in a Singapore tertiary center. Kidney transplant recipients who underwent pregnancy after transplantation at Singapore General Hospital between January 2001 and December 2012 were identified. Data on demographics, comorbidities and clinical outcomes were collected. There were 10 pregnancies identified in nine recipients. The median age of recipient at childbearing was 34.6 years (IQR, 32.8-36.8) and the median interval from transplantation to conception was 69 months (IQR, 38-97). There was no difference between the median pre-pregnancy estimated glomerular filtration rate (eGFR) (47.9 mL/min/1.73 m(2); IQR, 38.4-56.8) and median eGFR at time of last post-partum follow up (43.9 mL/min/1.73 m(2); IQR, 34.5-48.7, P = 0.549). Borderline allograft rejection occurred in one recipient (10.0%) 36 days after birth due to non-adherence to immunosuppressive medication, with subsequent allograft loss 37 months after birth. No mortalities were recorded during the study period. All the 10 pregnancies (100%) ended in singleton live births. Pre-eclampsia occurred in five pregnancies (50.0%), and there were seven (70.0%) preterm deliveries. The median gestational age was 35.4 weeks (IQR, 32.6-38.2) and the median birthweight was 2353 g (IQR, 1811-2648). Post-transplantation pregnancies ended successfully with no significant worsening of allograft function, but they were associated with risks to both recipients and newborns. © 2015 Japan Society of Obstetrics and Gynecology.

The current study uses magnetoencephalography (MEG) to characterize age-related changes and gender differences in the amplitudes and timing of cortical sources evoked by median nerve stimulation. Thirty-four healthy subjects from two age groups: 20-29 and >64 years of age were examined. After measuring the MEG responses, we modeled the data using a spatio-temporal multi-dipole modeling approach to determine the source locations and their associated timecourses. We found early, large amplitude responses in the elderly in primary somatosensory (approximately 20 ms) and pre-central sulcus timecourses (approximately 22 ms) and lower amplitude responses in the elderly later in primary somatosensory (approximately 32 ms) and contralateral secondary somatosensory timecourses (approximately 90 ms). In addition, females had larger peak amplitude responses than males in the contralateral secondary somatosensory timecourse (approximately 28 and 51 ms). These results show that the median nerve stimulation paradigm provides considerable sensitivity to age- and gender-related differences. The results are consistent with the theory that increased amplitudes identified in the elderly may be associated with decreased inhibition. The results emphasize that an examination of two discrete age groups, collapsed across gender, cannot provide a complete understanding of the fundamental changes that occur in the brain across the lifetime.

Amino acid racemization (AAR) is widely used as a cost-effective method to date molluscs in time-averaging and taphonomic studies, but it has not been attempted for echinoderms despite their paleobiological importance. Here we demonstrate the feasibility of AAR geochronology in Holocene aged Peronella peronii (Echinodermata: Echinoidea) collected from Sydney Harbour (Australia). Using standard HPLC methods we determined the extent of AAR in 74 Peronella tests and performed replicate analyses on 18 tests. We sampled multiple areas of two individuals and identified the outer edge as a good sampling location. Multiple replicate analyses from the outer edge of 18 tests spanning the observed range of D/Ls yielded median coefficients of variation < 4% for Asp, Phe, Ala, and Glu D/L values, which overlaps with the analytical precision. Correlations between D/L values across 155 HPLC injections sampled from 74 individuals are also very high (pearson r2 > 0.95) for these four amino acids. The ages of 11 individuals spanning the observed range of D/L values were determined using 14C analyses, and Bayesian model averaging was used to determine the best AAR age model. The averaged age model was mainly composed of time-dependent reaction kinetics models (TDK, 71%) based on phenylalanine (Phe, 94%). Modelled ages ranged from 14 to 5539 yrs, and the median 95% confidence interval for the 74 analysed individuals is ±28% of the modelled age. In comparison, the median 95% confidence interval for the 11 calibrated 14C ages was ±9% of the median age estimate. Overall Peronella yields exceptionally high-quality AAR D/L values and appears to be an excellent substrate for AAR geochronology. This work opens the way for time-averaging and taphonomic studies of echinoderms similar to those in molluscs.

Early diagnosis of autism spectrum disorders (ASD) enables early intervention that improves long term functioning of children with ASD but is often delayed until age of school entry. Few studies have identified factors that affect timely diagnosis. This study addressed how maternal education, race, age, marital status as well as neonatal birth factors affect the age at which a child is diagnosed with ASD. This study involved a retrospective analysis of 664 records of children treated at one of the largest autism treatment centers in the United States from March 1, 2009 to December 30, 2010. Logistic regression and Cox proportional hazards regression were used to identify maternal and neonatal factors associated with age of diagnosis. Infant gender, maternal race, marital status, and maternal age were identified as significant factors for predicting the age of ASD diagnosis. In the Cox proportional hazards regression model, only maternal race and marital status were included. Median survival age till diagnosis of children born to married mothers was 53.4 months compared to 57.8 months and 63.7 months of children born to single and divorced or widowed mothers respectively. Median survival age till diagnosis for children of African American mothers was 53.8 months compared to 57.2 months for children of Caucasian mothers. No statistically significant difference of timing of ASD diagnosis was found for children of varying gestational age. Children born to older or married mothers and mothers of minority races were more likely to have an earlier ASD diagnosis. No statistically significant differences in timing of ASD diagnosis were found for children born at varying gestational ages. Identification of these factors has the potential to inform public health outreach aimed at promoting timely ASD diagnosis. This work could enhance clinical practice for timelier diagnoses of ASD by supporting parents and clinicians around the world in identifying risk factors beyond gender and SES and developing strategies to recognize earlier signs of ASD and contribute to improved development outcomes in children with ASD.

To establish risks for development of hepatocellular carcinoma (HCC) in children with biliary atresia (BA), the most common chronic liver disease of childhood. In our tertiary referral center database we have identified children with BA who had development of or have been incidentally found to have HCC. Their demographic, clinical, radiologic, and histologic features were analyzed. Between 1990 and 2008, 387 infants were diagnosed with BA at our center. Of these, three (0.8 %) who underwent operation at a median age of 68 (range 66 to 71) days had development of a histologically proven HCC detected at a median age of 2.1 (range 1.8 to 4.9) years. Another two, referred later, were diagnosed with HCC on their liver explants at ages 1.1 and 17.75 years, respectively. Overall, two had elevated serum levels of alpha-fetoprotein. All five children underwent successful liver transplantation at a median age of 2.1 years (range 1.1 to 17.75) and remain well after a median of 2.5 (range 2 to 5.7) years. HCC develops in a small percentage of children with BA. Serum alpha-fetoprotein levels and ultrasound screening are helpful but not absolute markers of the malignant change. In the absence of the extrahepatic involvement, liver transplantation represents an effective treatment. Copyright © 2011 Mosby, Inc. All rights reserved.

Paraesophageal hernias (PEHs) involve herniation of stomach and/or other viscera into the mediastinum. These commonly occur in the elderly and can severely limit quality of life. Short term outcomes of repaired PEH demonstrated low morbidity and significant improvement in quality of life, but long-term data for all patients, especially the elderly, are lacking. Retrospective chart review of a prospectively collected database of patients aged 70 or greater with a symptomatic PEH repaired 5+ years ago. Quality of life data were assessed preoperatively, at 12-24 months, and at 5+ years using QOLRAD, GERD-HRQL, and DSS. We identified 137 patients who met the age criteria, with 69 patients undergoing surgery 5+ years ago. With ten patients were lost to follow-up, 59 patients were analyzed, including 24 males and 35 females. Median age at repair was 77 years. There were two 90-day mortalities, with one occurring within 30 days of surgery. Patients alive at evaluation had a median age of 74 years and were followed a median 7.4 years. From baseline, QOLRAD improved from 4 to 6.5, GERD-HRQL improved from 11 to 5, and swallowing improved from 11 to 38. During follow-up, 21 patients died. Deceased patients lived a median of 4 years after repair, with a median age at repair of 80 years. At a median time follow-up of 2 years, this group's QOLRAD improved from 5.1 to 7, GERD-HRQL improved from 16 to 4, and swallowing improved from 14.5 to 35. In elderly patients with symptomatic PEH undergoing surgical repair more than 5 years ago, there was sustained improvement in quality of life. This justifies surgical repair of symptomatic PEH in elderly patients.

Post-infarct ventricular tachycardia is associated with channels of surviving myocardium within scar characterized by fractionated and low-amplitude signals usually occurring late during sinus rhythm. Conventional automated algorithms for 3-dimensional electro-anatomic mapping cannot differentiate the delayed local signal of conduction within the scar from the initial far-field signal generated by surrounding healthy tissue. Ripple mapping displays every deflection of an electrogram, thereby providing fully informative activation sequences. We prospectively used CARTO-based ripple maps to identify conducting channels as a target for ablation. High-density bipolar left ventricular endocardial electrograms were collected using CARTO3v4 in sinus rhythm or ventricular pacing and reviewed for ripple mapping conducting channel identification. Fifteen consecutive patients (median age 68 years, left ventricular ejection fraction 30%) were studied (6 month preprocedural implantable cardioverter defibrillator therapies: median 19 ATP events [Q1-Q3=4-93] and 1 shock [Q1-Q3=0-3]). Scar (<1.5 mV) occupied a median 29% of the total surface area (median 540 points collected within scar). A median of 2 ripple mapping conducting channels were seen within each scar (length 60 mm; initial component 0.44 mV; delayed component 0.20 mV; conduction 55 cm/s). Ablation was performed along all identified ripple mapping conducting channels (median 18 lesions) and any presumed interconnected late-activating sites (median 6 lesions; Q1-Q3=2-12). The diastolic isthmus in ventricular tachycardia was mapped in 3 patients and colocated within the ripple mapping conducting channels identified. Ventricular tachycardia was noninducible in 85% of patients post ablation, and 71% remain free of ventricular tachycardia recurrence at 6-month median follow-up. Ripple mapping can be used to identify conduction channels within scar to guide functional substrate ablation. © 2016 American Heart Association, Inc.

Primary ovarian carcinoid tumors are rare neoplasms that constitute less than 0.1% of all ovarian carcinomas. However, carcinoid tumors metastatic to ovaries are more common. Cell proliferative rate is an important factor in the determination of neuroendocrine tumor prognosis. Limited data are available as regards Ki67 proliferation index in predicting the physiological features of carcinoid tumors involving the ovary. Pathology files of Mayo Clinic Rochester (1995-2014) were searched, and clinical information was collected from medical records. All cases were stained with an antibody against Ki67, and digital analysis was performed with digital imaging analysis. A total of 36 cases (median age 64 years, range 33-83 years), including 9 primary (median age 68 years, range 33-73 years) and 27 metastatic carcinoid cases (median age 64 years, range 36-83 years), were investigated in the current study. Seven out of nine (77.8%) primary ovarian carcinoids are associated with mature teratoma. Twenty two metastatic carcinoids (81.5%) were from the GI tract, four (14.8%) from the pancreas, and one (3.7%) from the posterior thorax location. There was significant difference of Ki67 index between primary (median 2.3%, range, 0.6-8.4%) and metastatic carcinoid tumors (median 9.7%, range, 1.3-46.7%) (p = 0.002). The survival time is much shorter among patients with metastatic carcinoid tumor (median survival 5.8 years) comparing to primary ovarian carcinoid tumor (median 14.2 years) (p = 0.0005). A strong association between Ki67 index and patient survival time was identified (Hazard ratio for 1-percentage point increase 1.11, p = 0.001). Comparing to primary ovarian carcinoid tumor, metastatic carcinoid usually exhibits a higher Ki67 index and a worse outcome.

To describe the dynamics of development along the early years of life among children living under unfavorable socioeconomic conditions. In 5401 children younger than 6 years old living in Florencio Varela and in the Matanza-Riachuelo River Basin (Matanza, Villa 21-24, Wilde, Villa Inflamable and Acuba), areas with a high proportion of families with unmet basic needs, a logistic regression analysis was used to estimate the median age at attainment of 13 psychomotor developmental milestones; differences between these ages and median age at attainment of milestones as per the national reference were plotted on the y-axis, while the median age as per the national reference was plotted on the x-axis. Three stages were observed: the first one between 0 and 270 days with normal development, in which the median age at attainment was similar to that of the national reference; a second one of progressive development delay; and a third one of recovery at 1260 days. Adjusted linear spline slopes were 0.06 (not significant), -0.26 (p < 0.0001) and 0.26 (p < 0.01) for stages 1, 2 and 3, respectively. The three slopes were statistically different from each other. The stage of normal development (stage 1) was attributed to the protective effect of the mother and the family environment; stage 2 of progressive delay, to the unfavorable impact of the environment, and stage 3 of partial recovery was attributed to attending a daycare center. These findings allow the implementation of effective interventions at each stage. Three periods with different developmental tempos were identified. Sociedad Argentina de Pediatría.

This study evaluated tolerability and efficacy of the ketogenic diet in infants less than 12 months of age. Infants less than 12 months of age, commencing the ketogenic diet between September 2007 and July 2016 were identified. Records were reviewed for epilepsy details, diet initiation details, efficacy and tolerability. Twenty-seven infants commenced the ketogenic diet (56% male, median age seven months). Median age at seizure onset was 1.9 months and 92% had daily seizures. An epilepsy syndrome was noted in 19 (West-11, epilepsy in infancy with migrating focal seizures-5, early myoclonic encephalopathy-1, Ohtahara-1, Dravet-1). Infants were on a median of two and had failed a median of one medications for lack of efficacy. All initiated a traditional ketogenic diet at full calories without fasting, and all but one started the diet in hospital. Significant hypoglycemia during initiation was seen in two - both had emesis +/- decreased oral intake. Eighty-eight percent developed urinary ketosis by 48 hours and all were successfully discharged on the diet (median ratio 3:1). Of those continuing dietary therapy, responder rates at one, six and 12 months were 68%, 82% and 91%, with 20%, 29% and 27% achieving seizure freedom. By 12 months, two stopped the diet for serious adverse effects, five discontinued for lack of efficacy, six were lost to follow-up and two died of unrelated causes. The ketogenic diet is an effective and well-tolerated treatment for infants with intractable epilepsy. In-hospital initiation is strongly recommended due to risk of hypoglycemia with emesis or reduced intake. Copyright © 2018 Elsevier Inc. All rights reserved.

The age of diagnosis of congenital hearing loss is one of the most important determinants of communication outcome. A previous study by the lead author had evaluated the performance of the public health services in Bloemfontein, South Africa (SA), in this regard. This study aimed to examine whether the private health services in the same city were any better. To determine whether the age of diagnosis of congenital hearing loss (CHL) in children seen in the private healthcare sector in Bloemfontein, Free State Province, SA, was lower than that in the public healthcare system in the same city. A comparative study design was utilised and a retrospective database review conducted. Data obtained from this study in the private healthcare sector were compared with data from a previous study in the public healthcare sector using the same study design. Forty-eight children aged <6 years with disabling hearing impairment (DHI) were identified in the private healthcare sector during the study period; 33/47 (70.2%) did not undergo hearing screening at birth. The median age of diagnosis of DHI in the private healthcare sector was 2.24 years, and this was statistically significantly lower than the median age of diagnosis of 3.71 years in the public healthcare sector (p<0.0001; 95% confidence interval (CI) 0.99-2.0). The median age of diagnosis of congenital hearing loss (CHL) in the private healthcare sector was 3.01 years in children who were not screened at birth, and 1.25 years in those who were screened at birth. This difference was statistically significant (p<0.01; 95% CI 0.72-2.47). We also compared the median age of diagnosis of CHL in children from the private healthcare sector who were not screened at birth (median 3.01 years) with that in children in the public healthcare sector (median 3.71 years). This difference was statistically significant (p<0.01; 95% CI 0.41-1.56). Children in the Free State are diagnosed with CHL at a younger age in the private healthcare sector than in the public healthcare sector. With the social and economic benefits of early intervention in cases of DHI well established internationally, SA healthcare providers in both the public and private sectors need to develop screening, diagnostic and (re)habilitation services for children with hearing impairment.

This study tests the hypothesis that most pedestrian collisions occur near victims' homes. Patients involved in automobile versus pedestrian collisions who presented to the emergency department at a Level I trauma center between January 2000 and December 2009 were included in the study. Patient demographics were obtained from the trauma registry. Home address was determined from hospital records, collision site was determined from the paramedic run sheet, and the shortest walking distance between the collision site and pedestrian residence was determined using Google Maps. We summarized distances for groups with the median and compared groups using the Kruskal-Wallis rank test. We identified 1917 pedestrian injury cases and identified both residence address and collision location for 1213 cases (63%). Forty-eight percent of the collisions were near home (within 1.1 km, 95% CI 45-51%). Median distance from residence to collision site was 1.4 km (interquartile range 0.3-7.4 km). For ages 0-17, the median distance 0.7 km, and 59% (95% CI 54-63%) of collisions occurred near home. For ages 65 and older, the median distance was 0.6 km and 65% (95% CI 55-73%) were injured near home. Distance did not differ by sex, race, ethnicity, or blood alcohol level. More severe injuries (Injury Severity Score ≥ 16) occurred further from home than less severe injuries (median 1.9 km vs. 1.3 km, p=.01). Patients with a hospital stay of 3 days or less were injured closer to home (median 1.3 km) than patients with a hospital stay of 4 days or more (median 1.8 km, p=.001). Twenty-two percent were injured within the same census tract as their home, 22% on the boundary of their home census tract, and 55% in a different census tract.

Epidemiological studies on myasthenia gravis (MG) in Mexico is mainly derived from experiences in referral centers. To describe the epidemiological characteristics of hospital discharges during 2010 with the diagnosis of MG in adults hospitalized in the Mexican public health system. We consulted the database of hospital discharges during 2010 of the National Health Information System (Ministry of Health, IMSS, IMSS oportunidades, ISSSTE, PEMEX, and the Ministry of Defense). The MG records were identified by the code G70.0 of the International Classification of Diseases 10th revision. During 2010 there were 5,314,132 hospital discharges (4,254,312 adults). Among them, 587 (0.01%) were adults with MG (median age: 47 years, 60% women). Women with MG were significantly younger than men (median age: 37 vs. 54 years, respectively; p < 0.001). The median hospital stay was six days. The case fatality rate was 3.4%, without gender differences. Age was associated with the probability of death. We confirmed the bimodal age-gender distribution in MG. The in-hospital case fatality rate in Mexico is consistent with recent reports around the world.

To establish the prevalence and patterns of use of touch-screen technologies in the toddler population. Parental questionnaires were completed for children aged 12 months to 3 years examining access to touch-screen devices and ability to perform common forms of interaction with touch-screen technologies. The 82 questionnaires completed on typically developing children revealed 71% of toddlers had access to touch-screen devices for a median of 15 min (IQR: 9.375-26.25) per day. By parental report, 24 months was the median age of ability to swipe (IQR: 19.5-30.5), unlock (IQR: 20.5-31.5) and active looking for touch-screen features (IQR: 22-30.5), while 25 months (IQR: 21-31.25) was the median age of ability to identify and use specific touch-screen features. Overall, 32.8% of toddlers could perform all four skills. From 2 years of age toddlers have the ability to interact purposefully with touch-screen devices and demonstrate a variety of common skills required to utilise touch-screen technology.

To assess medical resource utilization associated with Prader-Willi syndrome (PWS) in the US, hypothesized to be greater relative to a matched control group without PWS. We used a retrospective case-matched control design and longitudinal US administrative claims data (MarketScan) during a 5-year enrollment period (2009-2014). Patients with PWS were identified by Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code 759.81. Controls were matched on age, sex, and payer type. Outcomes included total, outpatient, inpatient and prescription costs. After matching and application of inclusion/exclusion criteria, we identified 2030 patients with PWS (1161 commercial, 38 Medicare supplemental, and 831 Medicaid). Commercially insured patients with PWS (median age 10 years) had 8.8-times greater total annual direct medical costs than their counterparts without PWS (median age 10 years: median costs $14 907 vs $819; P < .0001; mean costs: $28 712 vs $3246). Outpatient care comprised the largest portion of medical resource utilization for enrollees with and without PWS (median $5605 vs $675; P < .0001; mean $11 032 vs $1804), followed by mean annual inpatient and medication costs, which were $10 879 vs $1015 (P < .001) and $6801 vs $428 (P < .001), respectively. Total annual direct medical costs were ∼42% greater for Medicaid-insured patients with PWS than their commercially insured counterparts, an increase partly explained by claims for Medicaid Waiver day and residential habilitation. Direct medical resource utilization was considerably greater among patients with PWS than members without the condition. This study provides a first step toward quantifying the financial burden of PWS posed to individuals, families, and society. Copyright © 2016 The Authors. Published by Elsevier Inc.

No study has been conducted to investigate the spatial pattern and association of socioeconomic status (such as income) with breast and colorectal cancer incidence in Texas, United States. This study aimed to determine whether median household income was associated with the risk of developing breast and colorectal cancer in Texas and to identify higher cancer risks by race/ethnicity and geographic areas. This was a retrospective cohort study with an ecological component in using aggregated measures at the county level. We identified 243,677 women with breast cancer and 155,534 men and women with colorectal cancer residing in 254 counties in Texas in 1995-2011 from the public-use dataset of Texas Cancer Registry. The denominator population and median household income at the county level was obtained from the U.S. Bureau of the Census. Cancer incidence rates were calculated as number of cases per 100,000 persons and age-adjusted using the 2000 US population data. We used the ArcGIS v10.1 (geographic information system software) to identify multiple clustered counties with high and low cancer incidences in Texas. Age-adjusted breast cancer incidence rate in the highest median income quintile group was 151.51 cases per 100,000 in 2008-2011 as compared to 98.95 cases per 100,000 in the lowest median income quintile group. The risk of colorectal cancer appeared to decrease with increasing median income in racial/ethnic population. Spatial analysis revealed the significant low breast cancer incidence cluster regions located in southwest US-Mexico border counties in Texas. This study demonstrated that higher income was associated with an increased risk of breast cancer and a decreased risk of colorectal cancer in Texas. There were geographic variations with cancer incidence clustered in high risk areas in Texas. Future studies may need to explore more factors that might explain income and cancer risk associations and their geographic variations.

Background: Local control remains a challenge in pediatric parameningeal rhabdomyosarcoma (PM-RMS), and survival after local failure (LF) is poor. Identifying patients with a high risk of LF is of great interest to clinicians. In this study, we examined whether tumor response to induction chemotherapy (CT) could predict LF in embryonal PM-RMS. Methods: We identified 24 patients with embryonal PM-RMS, age 2 to 18 years, with complete magnetic resonance imaging and gross residual disease after surgical resection. All patients received proton radiation therapy (RT), median dose 50.4 Gy{sub RBE} (50.4-55.8 Gy{sub RBE}). Tumor size was measured before initial CT and before RT. Results:more » With a median follow-up time of 4.1 years for survivors, LF was seen in 9 patients (37.5%). The median time from the initiation of CT to the start of RT was 4.8 weeks. Patients with LF had a similar initial (pre-CT) tumor volume compared with patients with local controlled (LC) (54 cm{sup 3} vs 43 cm{sup 3}, P=.9) but a greater median volume before RT (pre-RT) (40 cm{sup 3} vs 7 cm{sup 3}, P=.009) and a smaller median relative percent volume reduction (RPVR) in tumor size (0.4% vs 78%, P<.001). Older age (P=.05), larger pre-RT tumor volume (P=.03), and smaller RPVR (P=.003) were significantly associated with actuarial LF on univariate Cox analysis. Conclusions: Poor response to induction CT appears to be associated with an increased risk of LF in pediatric embryonal PM-RMS.« less

2013-11-01

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease typically associated with elevated serum immunoglobulin G (IgG). Hypogammaglobulinemia in SLE patients has been attributed to immunosuppressive treatment or a transient effect associated with nephrotic syndrome. We retrospectively reviewed pediatric SLE patients from a single institution to identify patients with hypogammaglobulinemia and risk factors for hypogammaglobulinemia. A total of 116 pediatric SLE cases from 1997 to 2011 were reviewed and patients with hypogammaglobulinemia (IgG < 500 mg/dl) were identified. The two cohorts were evaluated for association with age, sex, presence of lupus nephritis at SLE diagnosis, disease activity at diagnosis, initial IgG level, and drug treatment. Eighty-six patients were included in our study, with a median age of 15 years and a median follow-up of 39.5 months. Seven percent (six of 86) of patients had hypogammaglobulinemia with a median onset of 27 months (0-72 months) after SLE diagnosis. Significant associations were noted for white race (p value 0.029), male sex (p value 0.009), and the presence of lupus nephritis at SLE diagnosis (p value 0.004). Use of immunosuppressive treatment did not show a statistical association with hypogammaglobulinemia, although two of the patients with hypogammaglobulinemia did receive rituximab. Most patients with hypogammaglobulinemia received intravenous immunoglobulin (IVIG) replacement therapy because of infections and/or concern for infection. Measurement of immunoglobulin levels during treatment in SLE could help identify patients with hypogammaglobulinemia who might require more aggressive follow-up to monitor for increased risk of infection and need for IVIG treatment. A prospective study is needed to validate associated risk factors identified in this study.

Purpose: To evaluate clinical and physico-dosimetric variables affecting clinical outcome of patients treated with Gamma Knife radiosurgery (GKRS) for brain metastases from non-small cell lung cancer (NSCLC). Methods and Materials: Between 2001 and 2006, 373 patients (298 men and 75 women, median age 65 years) with brain metastases from NSCLC underwent GKRS. All of them had KPS {>=} 60%, eight or fewer brain metastases, confirmed histopathological diagnosis and recent work-up (<3 months). Thirty-five patients belonged to recursive partitioning analysis (RPA) Class I, 307 patients were in RPA Class II, 7 patients were in RPA Class III. Median tumor volume wasmore » 3.6 cm{sup 3}. Median marginal dose was 22.5 Gy at 50% isodose.; median 10 Gy and 12 Gy isodose volumes were 30.8 cm{sup 3} and 15.8 cm{sup 3}, respectively. Follow-up with MRI was performed every 3 months. Overall survival data were collected from internal database, telephone interviews, and identifying registries. Results: Mean follow-up after GKRS was 51 months (range, 6 to 96 months); mean overall survival was 14.2 months. Of 373 patients, 29 were alive at time of writing, 104 had died of cerebral progression, and 176 had died of systemic progression. In 64 cases it was not possible to ascertain the cause. Univariate and multivariate analysis were adjusted for the following: RPA class, surgery, WBRT, age, gender, number of lesions, median tumor volume, median peripheral dose, and 10 Gy and 12 Gy volumes. Identified RPA class and overall tumor volume >5 cc were the only two covariates independently predictive of overall survival in patients who died of cerebral progression. Conclusions: Global volume of brain disease should be the main parameter to consider for performing GKRS, which is a first-line therapy for patient in good general condition and controlled systemic disease.« less

Inadequate iodine intake has been identified in populations considered iodine replete for decades. The objective of the current study is to evaluate urinary iodine concentration (UIC) and the probability of adequate iodine intake in subgroups of the Norwegian population defined by age, life stage and vegetarian dietary practice. In a cross-sectional survey, we assessed the probability of adequate iodine intake by two 24-h food diaries and UIC from two fasting morning spot urine samples in 276 participants. The participants included children ( n = 47), adolescents ( n = 46), adults ( n = 71), the elderly ( n = 23), pregnant women ( n = 45), ovo-lacto vegetarians ( n = 25), and vegans ( n = 19). In all participants combined, the median (95% CI) UIC was 101 (90, 110) µg/L, median (25th, 75th percentile) calculated iodine intake was 112 (77, 175) µg/day and median (25th, 75th percentile) estimated usual iodine intake was 101 (75, 150) µg/day. According to WHOs criteria for evaluation of median UIC, iodine intake was inadequate in the elderly, pregnant women, vegans and non-pregnant women of childbearing age. Children had the highest (82%) and vegans the lowest (14%) probability of adequate iodine intake according to reported food and supplement intakes. This study confirms the need for monitoring iodine intake and status in nationally representative study samples in Norway.

The global burden from cancer is rising, especially as low-income countries like Bangladesh observe rapid aging. So far, there are no comprehensive descriptions reporting diagnosed cancer group that include hematological malignancies in Bangladesh. This was a multi-center hospital-based retrospective descriptive study of over 5000 confirmed hematological cancer cases in between January 2008 to December 2012. Morphological typing was carried out using the "French American British" classification system. A total of 5013 patients aged between 2 to 90 years had been diagnosed with malignant hematological disorders. A 69.2% were males (n=3468) and 30.8% females (n=1545), with a male to female ratio of 2.2:1. The overall median age at diagnosis was 42 years. Acute myeloid leukemia was most frequent (28.3%) with a median age of 35 years, followed by chronic myeloid leukemia with 18.2% (median age 40 years), non-Hodgkin lymphoma (16.9%; median age 48 years), acute lymphoblastic leukemia (14.1%; median age 27 years), multiple myeloma (10.5%; median age 55 years), myelodysplastic syndromes (4.5%; median age 57 years) and Hodgkin's lymphoma (3.9%; median age 36 years). The least common was chronic lymphocytic leukemia (3.7%; median age 60 years). Below the age of 20 years, acute lymphoblastic leukemia was predominant (37.3%), followed by acute myeloid leukemia (34%). Chronic lymphocytic leukemia and multiple myeloma had mostly occurred among older patients, aged 50-over. For the first time, our study presents the pattern and distribution of diagnosed hematological cancers in Bangladesh. It shows differences in population distributions as compared to other settings with possibly a lower presence of non-Hodgkin lymphoma. There might be under-reporting of affected women. Further studies are necessary on the epidemiology, genetics and potential environmental risk factors within this rapidly aging country.

Historical research is limited in changes in pubertal development in Chinese girls. We aimed to identify the timing of pubertal characteristics and the secular trend of menarche age among Beijing girls from the 1980s through the 2000s. Six data sets were analyzed, including the Beijing Child and Adolescent Metabolic Syndrome study in 2004, where 9778 Bejing girls aged 6-18 years were studied. The Fetal Origins of Adult Disease study provided retrospective menarche age from 1940 through 1960. Other four studies were conducted in Beijing to obtain supplementary information to assess secular trend in menarche age. Linear regression method was used to analyze the data. Among Beijing girls in 2004, the median age at menarche was 12.1 years, which was 0.6 years earlier in urban than in rural areas. The median age at Breast Tanner Stage 2 was 9.5 ± 1.2 years, representing 9.4 ± 1.1 years and 9.6 ± 1.2 years for urban and rural girls, respectively. In contrast, the median age at Pubic Hair Tanner Stage 2 was 11.1 ± 1.1 years, representing 10.8 ± 1.1 and 11.4 ± 1.1 years for urban and rural girls, respectively. The menarche age of urban girls decreased by 4.2 months per decade, and that of rural girls by 9.6 months per decade from 1980 to 2004. Urban girls mature earlier than rural girls in Beijing. A secular trend towards earlier menarche was observed between the 1980s and the 2000s.

To determine the incidence of and factors associated with vitamin D deficiency rickets in Australian children. 18-month questionnaire-based prospective observational study, using Australian Paediatric Surveillance Unit (APSU) data. Australian paediatricians and child health workers, January 2006 - July 2007. Children aged ≤ 15 years with vitamin D deficiency rickets (25-hydroxyvitamin D [25OHD] ≤ 50 nmol/L, and elevated alkaline phosphatase levels [> 229 IU/L] and/or radiological rickets). Incidence of vitamin D deficiency rickets. Description of demographics, clinical presentation, identification and further analysis of overrepresented groups, and treatment regimens compared with best-practice guidelines. We identified 398 children with vitamin D deficiency (55% male; median age, 6.3 years [range, 0.2-15 years]). The overall incidence in children ≤ 15 years of age in Australia was 4.9/100 000/year. All had a low 25OHD level (median, 28 nmol/L [range, 5-50 nmol]) and an elevated alkaline phosphatase level (median, 407 IU/L [range, 229-5443 IU/L]), and 48 (12%) were hypocalcaemic. Ninety-five children had wrist x-rays, of whom 67 (71%) had rachitic changes. Most (98%) had dark or intermediate skin colour and 18% of girls were partially or completely veiled. Most children were born in Africa (252; 63%) and 75% of children were refugees. Duration of exclusive breastfeeding was inversely related to serum vitamin D levels in children < 3 years of age. Empirical vitamin D treatment was given to 4% of children before diagnosis. Vitamin D deficiency rickets is a significant problem in Australia among known high-risk groups. Public health campaigns to prevent, identify and tre@vitamin D deficiency, especially in high-risk groups, are essential.

We evaluated the temporal course of seizure outcome in children with pathology-confirmed focal cortical dysplasia and explored predictors of sustained seizure freedom. We performed a single-center retrospective study of children ≤ 18 years who underwent resective surgery from January 1, 2000 through December 31, 2012 and had pathology-proven focal cortical dysplasia. Surgical outcome was classified as seizure freedom (Engel class I) or seizure recurrence (Engel classes II-IV). Fisher exact and nonparametric Wilcoxon ranksum tests were used, as appropriate. Survival analysis was based on seizure-free outcome. Patients were censored at the time of seizure recurrence or seizure freedom at last follow-up. Thirty-eight patients were identified (median age at surgery, 6.5 years; median duration of epilepsy, 3.3 years). Median time to last follow-up was 13.5 months (interquartile range, 7-41 months). Twenty patients (53%) were seizure free and 26 patients (68%) attained seizure freedom for a minimum of 3 months. Median time to seizure recurrence was 38 months (95% confidence interval, 6-109 months), and the cumulative seizure-free rate was 60% at 12 months (95% confidence interval, 43%-77%). Clinical features associated with seizure freedom at last follow-up included older age at seizure onset (P = .02), older age at surgery (P = .04), absent to mild intellectual disability before surgery (P = .05), and seizure freedom for a minimum of 3 months (P < .001). Favorable clinical features associated with sustained seizure freedom included older age at seizure onset, older age at surgery, absent or mild intellectual disability at baseline, and seizure freedom for a minimum of 3 months.

Primary cytoreductive surgery (PDS) followed by platinum-based chemotherapy is the cornerstone of treatment and the absence of residual tumor after PDS is universally considered the most important prognostic factor. The aim of the present analysis was to evaluate trend and predictors of 30-day mortality in patients undergoing primary cytoreduction for ovarian cancer. Literature was searched for records reporting 30-day mortality after PDS. All cohorts were rated for quality. Simple and multiple Poisson regression models were used to quantify the association between 30-day mortality and the following: overall or severe complications, proportion of patients with stage IV disease, median age, year of publication, and weighted surgical complexity index. Using the multiple regression model, we calculated the risk of perioperative mortality at different levels for statistically significant covariates of interest. Simple regression identified median age and proportion of patients with stage IV disease as statistically significant predictors of 30-day mortality. When included in the multiple Poisson regression model, both remained statistically significant, with an incidence rate ratio of 1.087 for median age and 1.017 for stage IV disease. Disease stage was a strong predictor, with the risk estimated to increase from 2.8% (95% confidence interval 2.02-3.66) for stage III to 16.1% (95% confidence interval 6.18-25.93) for stage IV, for a cohort with a median age of 65 years. Metaregression demonstrated that increased age and advanced clinical stage were independently associated with an increased risk of mortality, and the combined effects of both factors greatly increased the risk.

Improvements in environmental conditions may result in an earlier onset of thelarche. However, its onset is not homogeneous among different population groups. To assess the relationship between nutritional status, ethnicity and age of thelarche. Cross-sectional study of girls in second through sixth grade, attending 165 schools located in Chile's Araucania region. Of these, 231 girls who presented thelarche (breast button) were selected. The girls' surnames were used to identify their ethnicity: indigenous had three or four last names of Mapuche indigenous origin (n =113), while non-indigenous were those who only had Chilean-Spanish last names (n =118). Weight, height, waist circumference and skinfold thicknesses were measured and socio-economic background information was collected through a home interview. The median age of thelarche was 10 years and 4 months, regardless of ethnic group. Multivariant models showed that an increase of one z score unit of body mass index (BMI) decreased the median age of thelarche by 5.6 months (CI: -7.24 to -3.90), controlling for the effect of different covariables. A decrease in one z score of height retards the median age of thelarche by 5.5 months (CI: 4.02 to 6.98). Ethnicity did not influence the age of thelarche. The age of thelarche found by us is similar to that reported in international studies, it comes earlier as weight increases, is delayed as height decreases and is not related to ethnicity.

Background Childhood Central Nervous System Primitive Neuro-Ectodermal brain Tumours (CNS-PNETs) are highly aggressive brain tumours for which molecular features and best therapeutic strategy remains unknown. We interrogated a large cohort of these rare tumours in order to identify molecular markers that will enhance clinical management of CNS-PNET. Methods Transcriptional and copy number profiles from primary hemispheric CNS-PNETs were examined using clustering, gene and pathways enrichment analyses to discover tumour sub-groups and group-specific molecular markers. Immuno-histochemical and/or gene expression analyses were used to validate and examine the clinical significance of novel sub-group markers in 123 primary CNS-PNETs. Findings Three molecular sub-groups of CNS-PNETs distinguished by primitive neural (Group 1), oligo-neural (Group 2) and mesenchymal lineage (Group 3) gene expression signature were identified. Tumour sub-groups exhibited differential expression of cell lineage markers, LIN28 and OLIG2, and correlated with distinct demographics, survival and metastatic incidence. Group 1 tumours affected primarily younger females; male: female ratios were respectively 0.61 (median age 2.9 years; 95% CI: 2.4–5.2; p≤ 0.005), 1.25 (median age 7.9 years; 95% CI: 6–9.7) and 1.63 (median age 5.9 years; 95% CI: 4.9–7.8) for group 1, 2 and 3 patients. Overall outcome was poorest in group 1 patients which had a median survival of 0.8 years (95% CI: 0.47–1.2; p=0.019) as compared to 1.8 years (95% CI: 1.4–2.3) and 4.3 years; (95% CI: 0.82–7.8) respectively for group 2 and 3 patients. Group 3 tumours had the highest incidence of metastases at diagnosis; M0: M+ ratio were respectively 0.9 and 3.9 for group 3, versus group 1 and 2 tumours combined (p=0.037). Interpretation LIN28 and OLIG2 represent highly promising, novel diagnostic and prognostic molecular markers for CNS PNET that warrants further evaluation in prospective clinical trials.

This study aimed to identify simple rules for allocating chronic obstructive pulmonary disease (COPD) patients to clinical phenotypes identified by cluster analyses.Data from 2409 COPD patients of French/Belgian COPD cohorts were analysed using cluster analysis resulting in the identification of subgroups, for which clinical relevance was determined by comparing 3-year all-cause mortality. Classification and regression trees (CARTs) were used to develop an algorithm for allocating patients to these subgroups. This algorithm was tested in 3651 patients from the COPD Cohorts Collaborative International Assessment (3CIA) initiative.Cluster analysis identified five subgroups of COPD patients with different clinical characteristics (especially regarding severity of respiratory disease and the presence of cardiovascular comorbidities and diabetes). The CART-based algorithm indicated that the variables relevant for patient grouping differed markedly between patients with isolated respiratory disease (FEV 1 , dyspnoea grade) and those with multi-morbidity (dyspnoea grade, age, FEV 1 and body mass index). Application of this algorithm to the 3CIA cohorts confirmed that it identified subgroups of patients with different clinical characteristics, mortality rates (median, from 4% to 27%) and age at death (median, from 68 to 76 years).A simple algorithm, integrating respiratory characteristics and comorbidities, allowed the identification of clinically relevant COPD phenotypes.

We have previously demonstrated that early primary repair of tetralogy of Fallot with pulmonary stenosis (TOF) can be safely performed without increase in hospital resource utilization or compromise to surgical technical performance scores (TPS). We sought to identify the optimal timing for elective early primary repair of TOF with respect to intermediate-term reintervention. Retrospective review of all patients with TOF undergoing elective primary repair between September 2004 and December 2013 was performed. Patients were stratified into reintervention group or no reintervention group. Multivariable Cox regression analysis identified independent predictors of reintervention. Youden's J-index in receiver operating characteristic analysis identified optimal age cutoff predictive of reintervention. Kaplan-Meier analysis with the log-rank test compared reintervention rates stratified by age and TPS. A total of 129 patients with median (interquartile range) age and weight of 78 days (56 to 111) and 5 kg (4.1 to 5.7), respectively, underwent primary repair. After a median (interquartile range) follow-up of 2.3 years (0.1 to 4.6), 18 patients (14%) required a total of 22 reinterventions. Youden's J-index revealed significantly lower risk of intermediate-term reintervention when repaired after 55 days of age (8% for >55 days old versus 31% for ≤55 days of age). Multivariable Cox regression identified age 55 days and younger (hazard ratio [HR] 4.5, 95% confidence interval [CI] 1.6 to 12.8, p = 0.004), valve sparing repair (HR 15.3, 95% CI 1.8 to 128.5, p < 0.001), residual right ventricular outflow tract (RVOT) gradient (HR 1.11, 95% CI 1.1 to 1.2, p < 0.001), and inadequate TPS (HR 21.5, 95% CI 7.4 to 63, p < 0.001) as independent predictors of overall intermediate-term reintervention. Elective repair in patients greater than 55 days of age, irrespective of size of the patient, can be safely performed without any increase in reintervention rates. Both residual peak RVOT gradient and TPS are effective in identifying patients at increased risk of reintervention. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc.

International guidelines recommend that severe asthma can only be diagnosed after contributory factors, including adherence, have been addressed. Accurate assessment of adherence is difficult in clinical practice. We hypothesised that electronic monitoring in children would identify nonadherence, thus delineating the small number with true severe asthma.Asthmatic children already prescribed inhaled corticosteroids were prospectively recruited and persistence of adherence assessed using electronic monitoring devices. Spirometry, airway inflammation and asthma control were measured at the start and end of the monitoring period.93 children (62 male; median age 12.4 years) were monitored for a median of 92 days. Median (range) monitored adherence was 74% (21-99%). We identified four groups: 1) good adherence during monitoring with improved control, 24% (likely previous poor adherence); 2) good adherence with poor control, 18% (severe therapy-resistant asthma); 3) poor adherence with good control, 26% (likely overtreated); and 4) poor adherence with poor control, 32%. No clinical parameter prior to monitoring distinguished these groups.Electronic monitoring is a useful tool for identifying children in whom a step up in treatment is indicated. Different approaches are needed in those who are controlled when adherent or who are nonadherent. Electronic monitoring is essential in a paediatric severe asthma clinic. Copyright ©ERS 2017.

Objective The critically ill, premature patients of neonatal intensive care units are susceptible to venous thrombosis, an adverse event associated with short- and long-term morbidity. Venous thrombosis is frequently treated with low molecular weight heparins (LMWH) such as enoxaparin, but optimal dosing of LMWH must balance the morbidity of venous thrombosis with the potential adverse affects of anticoagulation. The optimal dosing of enoxaparin for premature infants is unclear. The objective of this study was to describe enoxaparin therapy and follow-up in critically ill neonates diagnosed with venous thrombosis. Study Design Retrospective medical record review in the neonatal intensive care unit (NICU) in a single tertiary care institution. Infants with venous thrombosis diagnosed in the NICU were identified using pre-existing quality improvement lists and medical records. Results Twenty-six infants with 30 venous thromboses were identified with a median gestational age of 31 weeks at birth. Eighteen (69%) infants received enoxaparin for venous thrombosis during their hospitalization, beginning with a median dose of 1.5 mg/kg every 12h. This dose was increased to a median 2.1 mg/kg every 12h to achieve target anti-factor Xa levels. The target dose was significantly higher in patients with a postmenstrual age less than 37 weeks. Enoxaparin treatment was documented after discharge in 12 patients, continuing for a median of 99 days. Four patients died during hospitalization and their deaths were not attributable to venous thrombosis or anticoagulation complication. Follow-up documentation between 6 and 24 months after venous thrombosis diagnosis revealed no major morbidity of venous thrombosis or enoxaparin therapy. Conclusions Our data reinforces the relative safety and necessity of enoxaparin doses above 1.5 mg/kg per 12 hours in most neonates. This was particularly true for infants at lower postmenstrual age.

White matter development during childhood and adolescence is characterised by increasing white matter coherence and organisation. Commonly used scalar metrics, such as fractional anisotropy (FA), are sensitive to multiple mechanisms of white matter change and therefore unable to distinguish between mechanisms that change during development. We investigate the relationship between age and neurite density index (NDI) from neurite orientation dispersion and density imaging (NODDI), and the age-classification accuracy of NDI compared with FA, in a developmental cohort. Diffusion-weighted imaging data from 72 children and adolescents between the ages of 4-19 was collected (M=10.42, SD=3.99, 36 male). We compared NODDI metrics against conventional DTI metrics (fractional anisotropy [FA], mean diffusivity [MD], axial diffusivity [AD] and radial diffusivity [RD]) in terms of their relationship to age. An ROC analysis was also performed to assess the ability of each metric to classify older and younger participants. NDI exhibited a stronger relationship with age (median R 2 =.60) compared with MD (median R 2 =.39), FA (median R 2 =.27), AD (median R 2 =.14), and RD (median R 2 =.35) in a high proportion of white matter tracts. When participants were divided into an older and younger group, NDI achieved the best classification (median area under the curve [AUC]=.89), followed by MD (median AUC=.81), FA (median AUC=.80), RD (median AUC=.81), and AD (median AUC=.64). Our results demonstrate the sensitivity of NDI to age-related differences in white matter microstructural organisation over development. Importantly, NDI is more sensitive to such developmental changes compared to commonly used DTI metrics. This knowledge provides justification for implementing NODDI metrics in developmental studies.

It is necessary to develop a mechanism to estimate and analyze cumulative radiation risks from multiple CT exams in various clinical scenarios in children. To identify major contributors to high cumulative CT dose estimates using actual dose-length product values collected for 5 years in children. Between August 2006 and July 2011 we reviewed 26,937 CT exams in 13,803 children. Among them, we included 931 children (median age 3.5 years, age range 0 days-15 years; M:F = 533:398) who had 5,339 CT exams. Each child underwent at least three CT scans and had accessible radiation dose reports. Dose-length product values were automatically extracted from DICOM files and we used recently updated conversion factors for age, gender, anatomical region and tube voltage to estimate CT radiation dose. We tracked the calculated CT dose estimates to obtain a 5-year cumulative value for each child. The study population was divided into three groups according to the cumulative CT dose estimates: high, ≥30 mSv; moderate, 10-30 mSv; and low, <10 mSv. We reviewed clinical data and CT protocols to identify major contributors to high and moderate cumulative CT dose estimates. Median cumulative CT dose estimate was 5.4 mSv (range 0.5-71.1 mSv), and median number of CT scans was 4 (range 3-36). High cumulative CT dose estimates were most common in children with malignant tumors (57.9%, 11/19). High frequency of CT scans was attributed to high cumulative CT dose estimates in children with ventriculoperitoneal shunt (35 in 1 child) and malignant tumors (range 18-49). Moreover, high-dose CT protocols, such as multiphase abdomen CT (median 4.7 mSv) contributed to high cumulative CT dose estimates even in children with a low number of CT scans. Disease group, number of CT scans, and high-dose CT protocols are major contributors to higher cumulative CT dose estimates in children.

We report our experience in the elderly with aortic valve replacement using the Mitroflow A12 pericardial bioprosthesis. From January 1993 to January 2006, 491 patients over the age of 70 years received an aortic Mitroflow A12 bioprosthesis implantation. Concomitant procedures included coronary artery bypass grafting in 20% of patients. All patients had routine postoperative Echo-Doppler studies at discharge, one month and a mean of 11.1 months after surgery and annually thereafter. Twenty (4%) patients underwent a second aortic valve replacement due to bioprosthetic valve dysfunction (Group 2). Calcified stenosis was the most common finding at reoperation (98%). Median time to valve reoperation was 76 months. Of patients requiring reoperation, median age at first and second implantation was 73 (70-78) and 79 (76-83) years, respectively. For all patients, freedom from structural valve dysfunction (SVD) was 95+/-3% at 5 years and 55.8+/-2% at 10 years. Bioprosthetic valve deterioration was identified in 27 patients (Group 1). Median age of these patients at first operation and at diagnosis of deterioration by echo was 75 (70-84) and 77 (70-82) years, respectively. The median interval between operation and detection of bioprosthesis valve deterioration was 46 months. Among the total patient population, freedom from bioprosthetic deterioration was 85.7+/-2% at 5 years and 33.5+/-4% at 10 years. The Mitroflow A12 pericardial bioprosthesis provides less than optimal performance in elderly patients.

The aim of the study was to examine basal hypothalamic-pituitary-adrenal (HPA) axis activity and to determine associations of various covariates (gender, sleep-wake rhythm, demographic, academic, life style and health-related characteristics) with altered daily salivary cortisol profiles in late adolescence. The total analytic sample consisted of 903 Croatian secondary school students aged 18 - 21 years (median 19 years). Salivary cortisol was sampled at home at three time points over the course of one week and its concentrations were measured by using the enzyme immunoassay. In comparison to males, female students had a higher cortisol awakening response (CAR) (median 4.69, IQR 10.46 and median 3.03, IQR 8.94, respectively; P < 0.001), a steeper ("healthier") diurnal cortisol slope (DCS) (median 0.51, IQR 0.55 and median 0.44, IQR 0.51, respectively; P = 0.001), and a greater area under curve with respect to ground (AUC G ) (median 206.79, IQR 111.78 and median 191.46, IQR 104.18, respectively; P < 0.001). Those students who woke-up earlier and were awake longer, had a higher CAR (P < 0.001), a flatter ("less healthy") DCS (P < 0.001), and a greater AUCG (P < 0.001), than students who woke-up later and were awake shorter. Less consistent but still significant predictors of salivary cortisol indexes were age, school behaviour, friendship, diet healthiness and drug abuse. Gender and sleep-wake up rhythm were major determinants of the altered daily salivary cortisol profiles in late adolescence. The predictive power of other covariates, although less clear, has a potential for identifying vulnerable subgroups such as male drug users and females without a best friend.

Repeat liver transplantation (LT) is controversial because of inferior outcomes versus primary LT. A minimum 1-year expected post-re-LT survival of 50% has been proposed. We aimed to identify combinations of Model for End-Stage Liver Disease (MELD), donor risk index (DRI), and recipient characteristics achieving this graft survival threshold. We identified re-LT recipients listed in the United States from March 2002 to January 2010 with > 90 days between primary LT and listing for re-LT. Using Cox regression, we estimated the expected probability of 1-year graft survival and identified combinations of MELD, DRI, and recipient characteristics attaining >50% expected 1-year graft survival. Re-LT recipients (n = 1418) had a median MELD of 26 and median age of 52 years. Expected 1-year graft survival exceeded 50% regardless of MELD or DRI in Caucasian recipients who were not infected with hepatitis C virus (HCV) of all ages and Caucasian HCV-infected recipients <50 years old. As age increased in HCV-infected Caucasian and non-HCV-infected African American recipients, lower MELD scores or lower DRI grafts were needed to attain the graft survival threshold. As MELD scores increased in HCV-infected African American recipients, lower-DRI livers were required to achieve the graft survival threshold. Use of high-DRI livers (>1.44) in HCV-infected recipients with a MELD score > 26 at re-LT failed to achieve the graft survival threshold with recipient age ≥ 60 years (any race), as well as at age ≥ 50 years for Caucasians and at age < 50 years for African Americans. Strategic donor selection can achieve >50% expected 1-year graft survival even in high-risk re-LT recipients (HCV infected, older age, African American race, high MELD scores). Low-risk transplant recipients (age < 50 years, non-HCV-infected) can achieve the survival threshold with varying DRI and MELD scores. © 2015 American Association for the Study of Liver Diseases.

Objective: To describe factors associated with survival in Alzheimer disease (AD) in a multiethnic, population-based longitudinal study. Methods: AD cases were identified in the Washington Heights Inwood Columbia Aging Project, a longitudinal, community-based study of cognitive aging in Northern Manhattan. The sample comprised 323 participants who were initially dementia-free but developed AD during study follow-up (incident cases). Participants were followed for an average of 4.1 (up to 12.6) years. Possible factors associated with shorter lifespan were assessed using Cox proportional hazards models with attained age as the time to event (time from birth to death or last follow-up). In subanalyses, median postdiagnosis survival durations were estimated using postdiagnosis study follow-up as the timescale. Results: The mortality rate was 10.7 per 100 person-years. Mortality rates were higher among those diagnosed at older ages, and among Hispanics compared to non-Hispanic whites. The median lifespan of the entire sample was 92.2 years (95% CI: 90.3, 94.1). In a multivariable-adjusted Cox model, history of diabetes and history of hypertension were independently associated with a shorter lifespan. No differences in lifespan were seen by race/ethnicity after multivariable adjustment. The median postdiagnosis survival duration was 3.7 years among non-Hispanic whites, 4.8 years among African Americans, and 7.6 years among Hispanics. Conclusion: Factors influencing survival in Alzheimer disease include race/ethnicity and comorbid diabetes and hypertension.

Lynch syndrome and inflammatory bowel diseases (IBD) are associated with an increased risk of colorectal cancer (CRC). However, it is not clear whether the risk of CRC is even higher for patients with a combination of Lynch syndrome and IBD. We investigated the risk for CRC in this subgroup by establishing a Lynch syndrome cohort from the Radboud University Medical Center (Nijmegen, The Netherlands) and the Academic Medical Center (Amsterdam, The Netherlands). Patients with heterozygous germline mutations in MLH1, MSH2 (and EPCAM deletion-mediated MSH2 methylation), MSH6, or PMS2 who were tested and/or treated from 1998 through 2014 were included. Patients who developed IBD were identified by linkage of this cohort to the Dutch nationwide Pathology Registry (PALGA). Subsequently, we compared the risk of CRC between Lynch syndrome patients with IBD and without IBD. Of 1046 patients with Lynch syndrome, 15 developed IBD (1.4%). Patients with Lynch syndrome and IBD were significantly younger (median age, 38.0 y) than patients with Lynch syndrome without IBD (median age, 52.0 y; P = .001). Nevertheless, a similar proportion of patients in each group developed CRC: 4 of the 15 patients (26.7%) with Lynch syndrome and IBD compared with 311 of the 1031 patients (30.2%) with Lynch syndrome without IBD. Patients with Lynch syndrome and IBD developed CRC at a younger age (median age, 36.0 y) than patients with Lynch syndrome without IBD (median age, 46.0 y; P = .045). However, the cumulative incidence of CRC was similar between groups (P = .121). All patients with Lynch syndrome and IBD who developed CRC had ulcerative colitis, producing a higher cumulative incidence of CRC for this IBD subgroup (P < .001). In conclusion, patients with Lynch syndrome and IBD develop CRC risk at a younger age than patients without IBD; patients with ulcerative colitis are at especially high risk.

2017-10-06

Low fat-free mass (FFM) or high fat mass (FM) are abnormal body composition phenotypes associated with morbidity. These conditions in combination lead to worse health outcomes, and can be identified by a high FM/FFM ratio. Here, we developed sex, age, and body mass index (BMI) stratified, population-based FM/FFM reference values using bioelectrical impedance analysis (BIA) measurements. White, non-Hispanic individuals aged 18-90 years old with data for weight, stature and BIA resistance measures from the third National Health and Nutrition Examination Survey (NHANES) III were included. Previously validated and sex-specific BIA prediction equations were used to calculate FM and FFM. FM/FFM values were generated at 5th, 50th and 95th percentiles for each sex, age (18-39.9, 40-59.9, 60-69.9 and 70-90 years), and BMI category (underweight, normal weight, overweight, class I/II and class III obesity). A total of 6372 individuals who had estimated FM and FFM values were identified (3366 females, 3006 males). Median values of FM/FFM were 0.24 and 0.40 for young (≤39.9 years) males and females with normal BMI, and 0.34 for males and 0.59 for females who were overweight. For elderly individuals aged >70 years, median FM/FFM for males and females were respectively 0.28 and 0.45 for those with normal BMI, and 0.37 and 0.61 for those in the overweight category. These FM/FFM reference values provide information on body composition characteristics that account for age, sex and BMI, which can be useful to identify individuals at risk for body composition abnormalities.

Acquired hemophilia A (AHA), which is caused by autoantibodies against coagulation factor VIII (FVIII) is a rare, life-threatening bleeding disorder, the incidence of which appears to be increasing in Japan as the population ages. However, the clinical characteristics, treatment, and outcomes of AHA remain difficult to establish due to the rarity of this disease. We retrospectively analyzed data from 25 patients (median age 73 years; range 24-92 years; male n = 15) diagnosed with AHA between 1999 and 2015 at Gunma University Hospital. We identified autoimmune diseases and malignancy as underlying conditions in four and three patients, respectively. Factor VIII activity was significantly decreased in all patients (median 2.0%; range <1.0-8.0) by FVIII inhibitor (median 47.0 BU/mL; range 2.0-1010). Among 71 bleeding events, subcutaneous or intramuscular hemorrhage was the most prevalent. Seventeen patients required bypassing agents. Twenty-two (91.7%) of 24 patients treated with immunosuppressive agents achieved complete response (CR) during a median of 57.5 days (range 19-714 days). Although three patients (12%) relapsed and seven (28%) died of infection, none of the deaths were related to bleeding. Although most of our patients achieved CR after immunosuppressive therapy, the rate of infection-related mortality was unsatisfactorily high.

Purpose: To identify clinical and pathological factors that identify groups of women with stage I breast cancer with a 5-year risk of local recurrence (LR) ≤1.5% after breast-conserving therapy (BCS) plus whole-breast radiation therapy (RT). Methods and Materials: Study subjects were 5974 patients ≥50 years of age whose cancer was diagnosed between 1989 and 2006, and were referred with pT1 pN0 invasive breast cancer treated with BCS and RT. Cases of 5- and 10-year LR were examined using Kaplan-Meier methods. Recursive partitioning analysis was performed in patients treated with and without endocrine therapy to identify combinations of factors associated withmore » a 5-year LR risk ≤1.5%. Results: The median follow-up was 8.61 years. Median age was 63 years of age (range, 50 to 91). Overall 5-year LR was 1.5% (95% confidence interval [CI], 1.2%-1.9%) and 10-year LR was 3.4% (95% CI, 2.8%-4.0%). Of 2830 patients treated with endocrine therapy, patient subsets identified with 5-year LR ≤1.5% included patients with grade 1 histology (n=1038; LR, 0.2%; 95% CI, 0%-0.5%) or grade 2 histology plus ≥60 years of age (n=843; LR, 0.5%; 95% CI, 0%-1.0%). Ten-year LR for these groups were 0.8% (95% CI, 0.1%-1.6%) and 0.9% (95% CI, 0.2%-1.6%), respectively. Of 3144 patients treated without endocrine therapy, patients with grade 1 histology plus clear margins had 5-year LR ≤1.5% (n=821; LR, 0.6%; 95% CI, 0.1%-1.2%). Ten-year LR for this group was 2.2% (95% CI, 1.0%-3.4%). Conclusions: Histologic grade, age, margin status, and use of endocrine therapy identified 45% of a population-based cohort of female patients over age 50 with stage I breast cancer with a 5-year LR risk ≤1.5% after BCS plus RT. Prospective study is needed to evaluate the safety of omitting RT in patients with such a low risk of LR.« less

To study free- and protein-bound cobalamin absorption and the correlation with atrophic gastritis in healthy middle-aged and older subjects. A cross-sectional study. Fifty-two healthy subjects, aged 26 to 87 years, apparently free from conditions known to influence the cobalamin status. Middle-aged subjects were defined as those younger than 65 years of age (median age 57 years) and older subjects as those 65 years and older (median age 75 years). Protein-bound cobalamin absorption was assessed by 48-hour urinary excretion method following oral administration of scrambled egg yolk, labeled in vivo with 57 Co-cobalamin by injecting a hen with 57 Co-cyanocobalamin. The percentage of 57 Co-cobalamin bound to protein was 65%. Free cobalamin absorption was assessed by 48-hour urinary excretion method following oral administration of crystalline 57 Co-cyanocobalamin. Plasma cobalamin, folate and fasting plasma gastrin, and pepsinogen A and C concentrations were determined. The median urinary excretion of egg yolk 57 Co-cobalamin in middle-aged subjects was 12.3% (25th and 75th percentiles 10.5%-14.5%) compared with 11.7% (25th and 75th percentiles 9.8%-13.6%) in older subjects (P = .283). The median urinary excretion after administration of free 57 Co-cobalamin in middle-aged subjects was 25.7% (25th and 75th percentiles 20.6%-30.7%) compared with 27.9% (25th and 75th percentiles 21.4%-34.5%) in older subjects (P = .694). Neither egg yolk nor free 57 Co-cobalamin excretion correlated with age. A ratio of pepsinogen A to pepsinogen C less than 1.6, indicating atrophic gastritis, was found in 13 subjects. Within the atrophic gastritis group, 11 subjects had a pepsinogen A concentration greater than or equal to 17 micrograms/L, indicating mild to moderate atrophic gastritis, and two subjects had a pepsinogen A concentration less than 17 micrograms/L, indicating severe atrophic gastritis or gastric atrophy. All subjects had normal fasting plasma gastrin concentrations. Free and egg yolk 57 Co-cobalamin excretions were not reduced in the atrophic gastritis group when compared with the non-atrophic gastritis group. Median plasma cobalamin concentration was not significantly lower in older subjects (P = .205). Nonetheless, plasma cobalamin concentration correlated negatively with age (r = -.36; P = .008). We demonstrated no significant difference in either free or protein-bound cobalamin absorption between healthy middle-aged and older adults. In addition, no alteration in cobalamin absorption was found in subjects identified as having mild to moderate atrophic gastritis. Therefore, based on our results, the high prevalence of low cobalamin levels in older people cannot be explained by either the aging process or mild to moderate atrophic gastritis.

To determine whether treatment of lichen sclerosus et atrophicus (LS), with topical steroids reduces the rate of circumcision. Two independent reviewers performed a literature search of studies reporting treatment of LS with topical steroids using EMBASE and MEDLINE database(s). boys aged 0-18 years, clinical diagnosis of LS, treatment with topical steroids. Literature reviews, studies of phimosis without LS and adult patients were excluded. Data analysed for each paper included age, duration of treatment, length of follow up and outcome, notably circumcision or no surgery. The original search identified 26 titles. Application of exclusion criteria left 6 articles for inclusion in the study. Eighty nine patients with LS were treated with topical corticosteroids. Circumcision was avoided in 31/89 (35%; range 0-100%). Median patient age was 6.5 years (1 month-15 years). Median duration of treatment was 2 months (1-23 months); median follow-up 4 months (6 weeks-5 years). Treatment of LS with topical steroids reportedly avoided circumcision in 35% of boys. Duration of medical therapy and patient follow up in analysed studies were, however, short. A prospective randomised trial would provide a definitive answer. Systematic review. III.

To evaluate trends in the acquisition, storage, and utilization of donated corneal tissue in New Zealand, 2000 to 2009. The New Zealand National Eye Bank records were analyzed for the decade January 2000 to December 2009. Variables analyzed included donor demographics (age, sex, and ethnicity), donor source, donor cause of death, death-to-preservation interval (DPI), corneal storage time, tissue contamination, endothelial assessment, cornea suitability for transplantation, and corneal tissue utilization. A total of 1268 eye donors were identified during the 10-year period. Overall, 36% (n = 457) were female and 64% male (n = 813). Median donor age was 67 years, and 23% of donors were younger than 50 years (range, 5-90 years). There was a decrease in donor age over the decade (P = 0.006). The median DPI was 18.5 hours. No relationship was identified between cornea suitability for transplantation and DPI (P = 0.28) or donor gender (P = 0.54). There was a low microbial contamination rate (1%). Human immunodeficiency virus, hepatitis B, or hepatitis C serology was positive in 48 donors (4%). Overall, 90% of corneas were suitable for transplantation with a high utilization rate (88%). A novel association was identified between male sex and lower corneal endothelial cell density (P = 0.03). This New Zealand National Eye Bank analysis identified trends in the acquisition, storage, and utilization of donated corneal tissue throughout New Zealand over the past decade and provides valuable additional information to the international eye bank data.

Colon cancer is more common in the elderly than in younger and middle-aged people. Cancer clinical trials focus more on younger patients and the management of elderly patients with advanced disease is still unclear. We studied all patients presenting with colon adenocarcinoma metastasis to liver at a community teaching hospital from Dec 2000 through Dec 2007 by a retrospective review of Tumor Registry data and patient chart review with focus on age, clinical management, decision making, and survival. Sixty-seven patients with a median age of 69 and a male to female ratio of 31:36 were identified. The patients with obstructive symptoms and Eastern Cooperative Oncology Group performance status on presentation though varied little by age, smaller proportion of elderly patients underwent resection of the primary bowel tumor in the presence of liver metastases with ten of 16 (63%) aged 80 or greater being managed without surgery. The percentage of patient's preference to physician's preference for patients not undergoing the primary bowel resection increased for older age group. Median survival decreased significantly with age (p < 0.05). Age-related clinical management, decision-making autonomy, and survival are apparent in this study, and there was an increasing trend of patient's involvement in decision making as the age increases and, thus, affecting the age-related clinical management.

This study describes the timing of puberty in 8- to 14-year-old boys enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) and identifies factors associated with earlier achievement of advanced pubic hair stages. Women were enrolled during pregnancy and their offspring were followed prospectively. We analysed self-reported pubic hair Tanner staging collected annually. We used survival models to estimate median age of attainment of pubic hair stage >1, stage >2 and stage >3 of pubic hair development. We also constructed multivariable logistic regression models to identify factors associated with earlier achievement of pubic hair stages. Approximately 5% of the boys reported Tanner pubic hair stage >1 at age 8; 99% of boys were at stage >1 by age 14. The estimated median ages of entry into stages of pubic hair development were 11.4 years [95% confidence interval (CI) 11.3, 11.4] for stage >1, 12.7 years [95% CI 12.7, 12.8] for stage >2 and 13.5 years [95% CI 13.5, 13.6] for stage >3. Predictors of younger age at Tanner stage >1 included low birthweight, younger maternal age at delivery and being taller at age 8. Associations were found between younger age at attainment of stage >2 and gestational diabetes and taller or heavier body size at age 8. Being taller or heavier at age 8 also predicted younger age at Tanner stage >3. The results give added support to the strong influence of pre-adolescent body size on male pubertal development; the tallest and heaviest boys at 8 years achieved each stage earlier and the shortest boys later. Age at attainment of pubic hair Tanner stages in the ALSPAC cohort are similar to ages reported in other European studies that were conducted during overlapping time periods. This cohort will continue to be followed for maturational information until age 17. © 2010 Blackwell Publishing Ltd.

Aging is one of the most complicated phenomena and is the main risk factor for age-related diseases. Based on the public aging-related gene data, we propose a computational approach to predict the antiaging activities of compounds. This approach integrates network pharmacology and target fishing methods with the aim of identifying a potential antiaging compound from Scutellaria baicalensis Georgi. Utilizing this approach and subsequent experimental validation, it was found that baicalein at concentrations of 0.04, 0.2, and 1 mg/mL extended the mean, median, and maximum life spans in Drosophila melanogaster. Particularly, 0.2 mg/mL baicalein extends the mean and median life spans in male flies by 19.80% and 25.64%, respectively. Meanwhile, it was discovered that baicalein improved fertility in flies. Baicalein exerts antiaging effects likely through attenuating oxidative stress, including increases of CAT activity and GSH level and decrease of GSSG level.

The Hirsch index (h-index) is recognized as an effective way to summarize an individual's scientific research output. However, a benchmark for evaluating surgeon scientists in the field of hepatic surgery is still not available. A total of 3,251 authors who published between 1949 and 2011 were identified using the Scopus identification number. The h-index, the total number of cited document, the total number of citations, and the scientific age were calculated for each author using both Scopus and Google Scholar. The median h-index was 6 and the median scientific age, assessed with Google Scholar, was 19 years. The numbers of cited documents, numbers of citations, and h-indexes obtained from Scopus and Google Scholar showed good correlation with one another; however, the results from the 2 databases were modified in different ways by scientific age. By plotting scientific age against h-index percentiles an h-index growth chart for both Scopus database and Google Scholar was provided. This analysis provides a first benchmark to assess surgeon scientists' productivity in the field of liver surgery. Copyright © 2013 Elsevier Inc. All rights reserved.

To determine the frequency of radiographic abnormalities in hand/wrist radiographs of children with newly diagnosed polyarticular juvenile rheumatoid arthritis (polyJRA) because radiographs of small joints are an important tool in assessing outcomes in RA and there are clinical similarities between RA and polyJRA. A medical record review was performed to identify cases of polyJRA seen at Mayo Clinic from January 1, 1994, to December 31, 2001. Hand/wrist radiographs, obtained at the time of diagnosis, were reviewed by 3 radiologists with attention to periarticular osteopenia, joint space narrowing (JSN), or erosion. At least 2 radiologists had to independently identify abnormal findings on the same radiograph. The relative carpal length (RCL), judged by Poznanski's method, was also determined. From the review of 159 medical records, 60 cases of newly diagnosed polyJRA were identified. Twenty-five of these had hand/wrist radiographs at diagnosis; 18 sets were available for this study. Of those, 2/3 were female, 6% (1/18) had subcutaneous nodules, 7% (1/14) had elevated levels of serum rheumatoid factor, and 44% (7/16) had elevated serum levels of antinuclear antibodies. Median age at diagnosis was 10.2 years, median duration of hand/wrist symptoms at diagnosis was 10 months, and median number of joints with either swelling, pain on range of motion (ROM), or limited ROM was 14.5. Sixty-one percent of radiographs taken at the time of diagnosis of polyJRA were abnormal. While 44% had periarticular osteopenia, 28% had either erosions or JSN. Six (33%) had RCL > 2 SD below the mean for age. Five (83%) of those with RCL, > 2 SD below the mean for age, had periarticular osteopenia, JSN, or erosion. We conclude the frequency of abnormal hand/wrist radiographs is very high very early in the course of polyJRA. More studies are needed to determine to what extent these radiographic abnormalities correlate with clinical outcomes.

The natural history of ductal carcinoma in situ (DCIS) remains uncertain. The risk factors for the development of invasive cancer in unresected DCIS are unclear. Women diagnosed with DCIS on needle biopsy after 1997 who did not undergo surgical resection for ≥1 year after diagnosis were identified by breast centres and the cancer registry and outcomes were reviewed. Eighty-nine women with DCIS diagnosed 1998-2010 were identified. The median age at diagnosis was 75 (range 44-94) years with median follow-up (diagnosis to death, invasive disease or last review) of 59 (12-180) months. Twenty-nine women (33%) developed invasive breast cancer after a median interval of 45 (12-144) months. 14/29 (48%) with high grade, 10/31 (32%) with intermediate grade and 3/17 (18%) with low grade DCIS developed invasive cancer after median intervals of 38, 60 and 51 months. The cumulative incidence of invasion was significantly higher in high grade DCIS than other grades (p = .0016, log-rank test). Invasion was more frequent in lesions with calcification as the predominant feature (23/50 v. 5/25; p = .042) and in younger women (p = .0002). Endocrine therapy was associated with a lower rate of invasive breast cancer (p = .048). High cytonuclear grade, mammographic microcalcification, young age and lack of endocrine therapy were risk factors for DCIS progression to invasive cancer. Surgical excision of high grade DCIS remains the treatment of choice. Given the uncertain long-term natural history of non-high grade DCIS, the option of active surveillance of women with this condition should be offered within a clinical trial. Crown Copyright © 2018.

The efficacy of enzyme replacement therapy (ERT) in patients at an advanced stage of Pompe disease has only been addressed in a few studies. Our objective was to assess the long term effects of ERT in a cohort of patients with severe Pompe disease. We identified patients from the French Pompe Registry with severe respiratory failure and permanent wheelchair use (assisted walk for a few meters was allowed) when starting ERT. Patients' medical records were collected and reviewed and respiratory and motor functions, before ERT initiation and upon last evaluation were compared. Twelve patients (7 males) were identified. Median age at symptom onset was 24years [IQR=15.5; 36.0]. At baseline ventilation was invasive in 11 patients and noninvasive in one, with a median ventilation time of 24h [IQR=21.88; 24.00] (min 20; max 24). ERT was initiated at a median age of 52.5years [IQR=35.75; 66.50]. Median treatment duration was 55months [IQR=39.5; 81.0]. During observational period no adverse reaction to ERT was recorded, five patients (41.67%) died, three decreased their ventilation time by 30, 60 and 90min and two increased their assisted walking distance, by 80 and 20m. Some patients at a very advanced stage of Pompe disease may show a mild benefit from ERT, in terms of increased time of autonomous ventilation and of enlarged distance in assisted walk. ERT can be initiated in these patients in order to retain their current level of independence and ability to perform daily life activities. Copyright © 2017 Elsevier Inc. All rights reserved.

Purpose: To retrospectively evaluate the treatment outcome of patients with Merkel cell carcinoma after local and/or regional treatment. Methods and Materials: Patients presenting to our center between January 1980 and July 2006 with Merkel cell carcinoma and without distant metastases were reviewed. The primary endpoint was locoregional control. Secondary endpoints were distant recurrence, survival and treatment toxicity. Results: A total of 176 patients were identified. The median age was 79 years. The median follow-up was 2.2 years for all patients and 3.9 years for those alive at the last follow-up visit. The most common primary site was the head andmore » neck (56%), and 62 patients(35%) had regional disease at presentation. The initial surgery to the primary tumor involved (wide) local excision in 140 patients and biopsy only in 28 patients (8 patients had no identifiable primary tumor); 33 patients underwent nodal surgery. Of the 176 patients, 165 (94%) underwent radiotherapy (RT) and 29 of them also underwent concurrent chemotherapy. The median radiation dose was 50 Gy (range, 18-60). Locoregional recurrence developed in 33 patients(19%), with a median interval to recurrence of 8 months. Distant metastases developed in 43 patients(24%). Age, primary tumor size, and RT (no RT vs. <45 Gy vs. {>=}45 Gy) were predictive of locoregional control on univariate analysis. However, only RT remained significant on multivariate analysis. The estimated 5-year actuarial rate for locoregional control, progression-free survival, and overall survival was 76%, 60%, and 45%, respectively. Conclusion: The locoregional control rate for Merkel cell carcinoma in our study was comparable to those from other series using combined modality treatment with RT an integral part of treatment.« less

Lead, mercury and polychlorinated biphenyls (PCBs) are neurotoxicants with intergenerational health consequences from maternal body burden and gestational exposures. Little is known about multiple chemical exposures among childbearing-aged women. To determine the percentage of women aged 16-49 of diverse races and ethnicities whose body burdens for all three xenobiotics were at or above the median; to identify mixed exposures; and to describe those women disproportionately burdened by two or more of these chemicals based on susceptibility- and exposure-related attributes, socioeconomic factors and race-ethnicity. Secondary data analysis of National Health and Nutrition Examination Survey (1999-2004). The best-fit logistic regression model without interactions contained 12 variables. Four risk factors associated with body burden were notable (P≤0.05). An exponential relationship was demonstrated with increasing age. Any fish consumption in past 30 days more than doubled the odds. Heavy alcohol consumption increased the relative risk. History of breastfeeding reduced this risk. These women were more likely to have two xenobiotics at or above the median than one. More than one-fifth of these childbearing-aged women had three xenobiotic levels at or above the median. These findings are among the first description of US childbearing-aged women's body burden and risk factors for multiple chemical exposures. This study supports increasing age, any fish consumption and heavy alcohol consumption as significant risk factors for body burden. History of breastfeeding lowered the body burden. Limited evidence was found of increased risk among minority women independent of other risk factors. Copyright © 2012 Elsevier Inc. All rights reserved.

Chronic lymphocytic leukemia is a disease of the elderly, and despite major advances in treatment, remains incurable. The Cancer Registry of Norway has registered data on patients with chronic lymphocytic leukemia since 1953. We aimed to analyze trends in incidence and survival of chronic lymphocytic leukemia in Norway. We identified 7664 patients reported with chronic lymphocytic leukemia to the registry between 1953 and 2012. We gathered information on sex, age at diagnosis, date of death and basis for diagnosis. The age-standardized incidence increased from 0.6/100.000 person-years in 1953 to 3.1/100,000 person-years in 2012. We found a significant decrease in median age between 1993-2002 and 2003-2012 (75 vs. 72 years, 95%CI: 2.52-3.98, P < 0.001). Men were diagnosed at a significantly younger age than women. Immunophenotyping has become the most important diagnostic method after 2002. Median observed survival increased from 3 years in 1952-1963 to 8.5 years in 2003-2012. Five- and 10-year age-standardized net survival increased throughout the whole period across age groups and reached 79% and 57%, respectively. Median observed survival was significantly shorter in men than in women in 1993-2002 (4.9 vs. 6.1 years, P < 0.001). The gap between survival rates for men and women was diminishing in 2003-2012 in patients younger than 60 years while it remained considerable in older patients. Despite an aging Norwegian population, chronic lymphocytic leukemia (CLL) patients become younger at diagnosis. A fourfold increase in incidence, a prolonged survival, and major changes in diagnostic methods in Norway were observed. © 2016 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Context: Heterozygous mutations in the aggrecan gene (ACAN) cause autosomal dominant short stature with accelerated skeletal maturation. Objective: We sought to characterize the phenotypic spectrum and response to growth-promoting therapies. Patients and Methods: One hundred three individuals (57 females, 46 males) from 20 families with autosomal dominant short stature and heterozygous ACAN mutations were identified and confirmed using whole-exome sequencing, targeted next-generation sequencing, and/or Sanger sequencing. Clinical information was collected from the medical records. Results: Identified ACAN variants showed perfect cosegregation with phenotype. Adult individuals had mildly disproportionate short stature [median height, −2.8 standard deviation score (SDS); range, −5.9 to −0.9] and a history of early growth cessation. The condition was frequently associated with early-onset osteoarthritis (12 families) and intervertebral disc disease (9 families). No apparent genotype–phenotype correlation was found between the type of ACAN mutation and the presence of joint complaints. Childhood height was less affected (median height, −2.0 SDS; range, −4.2 to −0.6). Most children with ACAN mutations had advanced bone age (bone age − chronologic age; median, +1.3 years; range, +0.0 to +3.7 years). Nineteen individuals had received growth hormone therapy with some evidence of increased growth velocity. Conclusions: Heterozygous ACAN mutations result in a phenotypic spectrum ranging from mild and proportionate short stature to a mild skeletal dysplasia with disproportionate short stature and brachydactyly. Many affected individuals developed early-onset osteoarthritis and degenerative disc disease, suggesting dysfunction of the articular cartilage and intervertebral disc cartilage. Additional studies are needed to determine the optimal treatment strategy for these patients. PMID:27870580

To determine age-specific serum anti-Müllerian hormone (AMH) values for women presenting to U.S. fertility clinics. Retrospective study. Single clinical reference laboratory. A total of 17,120 women of reproductive age ranging from 24 to 50 years old. None. Determination of single-year median and mean AMH values with SDs. Single-year-specific median, mean, and SD values are summarized in Table 1. Both median and mean AMH values decreased steadily in a manner highly correlated with advancing age. The average yearly decrease in the median serum AMH value was 0.2 ng/mL/year through age 35 and then diminished to 0.1 ng/mL/year after age 35. The rate of decline in mean AMH values was 0.2 ng/mL/year through age 40 and then diminished to 0.1 ng/mL/year thereafter. Median and mean AMH levels decreased steadily with increasing age from 24 to 50 years of age. Such data may be of value to physicians and their patients who are considering reproductive options.

Elderly patients are often judged to be fit for emergency surgery based on age alone. This study identified risk factors predictive of in-hospital mortality amongst octogenarians undergoing emergency general surgery. A retrospective review of octogenarians undergoing emergency general surgery over 3 years was performed. Parametric survival analysis using Cox multivariate regression model was used to identify risk factors predictive of in-hospital mortality. Hazard ratios (HR) and corresponding 95% confidence interval were calculated. Seventy-three patients with a median age of 84 years were identified. Twenty-eight (38%) patients died post-operatively. Multivariate analysis identified ASA grade (ASA 5 HR 23.4 95% CI 2.38-230, p = 0.007) and chronic obstructive pulmonary disease (COPD) (HR 3.35 95% CI 1.15-9.69, p = 0.026) to be the only significant predictors of in-hospital mortality. Identification of high risk surgical patients should be based on physiological fitness for surgery rather than chronological age. Crown Copyright © 2014. Published by Elsevier Ltd.

Patients presenting with a sudden drop in the pleural fluid level after a pneumonectomy in the absence of a recognizable bronchopleural fistula (BPF) have been classified as cases of benign emptying of the post-pneumonectomy space (BEPS). A retrospective study of 1378 pneumonectomies identified 4 cases of BEPS (0.29%). The patients were men; median age 64 years and all had undergone a right pneumonectomy. The median time at diagnosis was 31 days postoperatively and the median follow-up time was 31 months. None of the patients experienced a documented BPF or empyema. Although BEPS is an extremely rare complication, early recognition and close patient monitoring will prevent unnecessary interventional strategies. © The Author 2015.

Indicators of abdominal size relative to height associated with sex, age, socioeconomic position and ancestry among US adults.

PubMed

Kahn, Henry S; Bullard, Kai McKeever

2017-01-01

The supine sagittal abdominal diameter (SAD) and standing waist circumference (WC) describe abdominal size. The SAD/height ratio (SADHtR) or WC/height ratio (WHtR) may better identify cardiometabolic disorders than BMI (weight/height2), but population-based distributions of SADHtR and WHtR are not widely available. Abdominal adiposity may differ by sociodemographic characteristics. Anthropometry, including SAD by sliding-beam caliper, was performed on 9894 non-pregnant adults ≥20 years in the US National Health and Nutrition Examination Surveys of 2011-2014. Applying survey design factors and sampling weights, we estimated nationally representative SADHtR and WHtR distributions by sex, age, educational attainment, and four ancestral groups. The median (10th percentile, 90th percentile) for men's SADHtR was 0.130 (0.103, 0.165) and WHtR 0.569 (0.467, 0.690). For women, median SADHtR was 0.132 (0.102, 0.175) and WHtR 0.586 (0.473, 0.738). Medians for SADHtR and WHtR increased steadily through age 79. The median BMI, however, reached maximum values at ages 40-49 (men) or 60-69 (women) and then declined. Low educational attainment, adjusted for age and ancestry, was associated with elevated SADHtR more strongly than elevated BMI. While non-Hispanic Asians had substantially lower BMI compared to all other ancestral groups (adjusted for sex, age and education), their relative reductions in SADHtR and WHtR, were less marked. These cross-sectional data are consistent with monotonically increasing abdominal adipose tissue through the years of adulthood but decreasing mass in non-abdominal regions beyond middle age. They suggest also that visceral adipose tissue, estimated by SADHtR, expands differentially in association with low socioeconomic position. Insofar as Asians have lower BMIs than other populations, employing abdominal indicators may attenuate the adiposity differences reported between ancestral groups. Documenting the distribution and sociodemographic features of SADHtR and WHtR supports the clinical and epidemiologic adoption of these adiposity indicators.

The prevalence of proximal hamstring pathology on MRI in the asymptomatic population.

Injury to the proximal hamstring complex (PHC) is becoming more frequently diagnosed. Patients attending our tertiary referral centre demonstrated 'pathological changes' in the unaffected normal contralateral PHC on MRI. The prevalence of PHC pathology, however, has not been previously documented in the literature in asymptomatic subjects. It is the hypothesis of this study that the natural history of asymptomatic pathological change on MRI in the PHC is not clear. The aim is to quantify the natural history of PHC degeneration. Two hundred and fifty-three consecutive patients with an asymptomatic PHC were reviewed retrospectively between 2009 and 2010. The PHC was assessed in multiple MRI planes by a specialist musculoskeletal consultant radiologist. Five hundred and six proximal hamstrings complexes were reviewed. Eighty-nine patients (35 %) were radiological normal both sides, median age 51 years (range 13-88). Thirty-four patients (13 %) had unilateral pathology, median age 55 years (range 25-89). Of these, 3 patients (1 %) had presence of a complete tear, median age 81 years (range 72-87). Sixteen patients (7 %) had tendinosis, median age 60 years (range 37-78). Fifteen patients (6 %) had a unilateral partial tear, median age 57 years (range 35-78). One hundred and thirty patients (52 %) had bilateral pathology, median age 65 years (range 25-89). Fifty-three patients (21 %) had the presence of bilateral tendinopathy alone, median age 56 years (range 25-89). Twenty-seven patients (11 %) had a partial tear on one side and tendinosis on the other, median age 68 years (range 38-89). Thirty-nine patients (15 %) had evidence of bilateral partial tears, median age 63 years (range 36-89), with 52 % demonstrating a torn conjoined and semi-membranosus tendon. The remaining 48 % had either an isolated tear of the conjoined or the semi-membranosus (the more commonly injured tendon 74 % of the time). Four patients (2 %) had bilateral complete ruptures with a median age of 68 years (range 59-78). Six patients (2 %) had a complete tear on one side and a partial tear on the other, median age 68 years (range 34-83). One patient had a complete tear on one side and tendinosis on the other, age 81 years. There is a higher prevalence of pathology in the asymptomatic population, 15 % have bilateral partial tears, and 2 % have bilateral complete tears. The semi-membranosus being the most affected, this may help clinically stratify the need for surgical intervention. I.

The register of activity at the Ebola Treatment Center (ETC) in Forecariah (Guinea), from April 23 to June 5, 2015 is presented for analysis. The viral load of each patient is evaluated by the cycle threshold (Ct). One hundred and thirty patients were seen in Triage at the ETC, of which 24 (18.5%) patients who failed to meet theWHO case criteria for viral hemorrhagic fever were excluded from admission to the ETC. Of the 106 patients admitted in the ETC, 72 (67.9%) were declared non-cases after the results of their two PCR (drawn 48 hours apart) tests were negative. Thirty-four patients were tested positive for Ebola virus disease (EVD): 19 women and 15 men (sex ratio: male/female = 0.78), mean age of 33.51 ± 20.1 years (extremes of 42 days to 70 years), of which six children were aged below 8 years. The median initial Ct value was 21.6 ± 6.3 cycles in this group. Enquiry into patient contacts was only able to identify actual contacts in 20 of these patients (58.8%). Thirteen patients were ultimately cured of EVD (six men and seven women) - with a median age of 31.8 years (extremes of 4 to 54 years). These patients presented on admission with a median Ct value of 21.88 ± 6.2 cycles (extremes of 17.6 to 31.7). Of the six children aged below 8 years, only one survived. Twenty-one patients (61.76%) with EVD died (9 men and 12 women) - median age, 34 ± 21 years (extremes of 42 days to 70 years). They presented on admission with a median Ct value of 18 ± 7 cycles (extremes of 12 to 24). The single most important factor associated with lethality was the Ct value at the time of admission to the ETC (P = 0.0004), i.e., the lower the Ct value, the higher the lethality rate or simply stated, the higher the viral load, the greater the lethality. Age, sex, identification of contact, and delay between the onset of symptoms and admission did not prove to be predictive of death outcome in our series.

Progressive multifocal leukoencephalopathy (PML) is a rare and potentially fatal condition caused by a brain infection with JC polyomavirus (JCV). PML develops almost exclusively in immunocompromised patients and has recently been associated with use of fumaric acid esters (FAEs), or fumarates. We reviewed the literature and the Dutch and European pharmacovigilance databases in order to identify all available FAE-associated PML cases and distinguish possible common features among these patients. A total of 19 PML cases associated with FAE use were identified. Five cases were associated with FAE use for multiple sclerosis and 14 for psoriasis. Ten patients were male and nine were female. The median age at PML diagnosis was 59 years. The median duration of FAE therapy to PML symptom onset or appearance of first PML lesion on brain imaging was 31 months (range 6-110). In all cases a certain degree of lymphocytopenia was reported. The median duration of lymphocytopenia to PML symptom onset was 23 months (range 6-72). The median lymphocyte count at PML diagnosis was 414 cells/µL. CD4 and CD8 counts were reported in ten cases, with median cell count of 137 and 39 cells/µL, respectively. Three patients died (16% mortality). The association between occurrence of PML in patients with low CD4 and CD8 counts is reminiscent of PML cases in the HIV population and suggests that loss of T cells is the most important risk factor.

The aim of this study was to report on results of uveal melanoma treatment with ruthenium-106 ( 106 Ru) brachytherapy with long-term follow-up, in terms of local tumor control, eye retention rate, radiation retinopathy, and patients' survival. Medical records of patients treated with ruthenium plaque due to uveal melanoma at the Department of Ophthalmology, Poznan University of Medical Sciences, Poland, between 1994 and 2014 were retrospectively reviewed. We identified 126 patients: 53 men, 73 women, mean age 60.04 years (range, 21-89). The largest basal diameter ranged from 4.04 mm to 18.9 mm (median, 10.67 mm), tumor height was 1.9 mm to 7.42 mm (median, 4.8 mm). Median scleral radiation dose was 570 Gy (range, 235-1,500 Gy), median apical dose 100 Gy (range, 60-129 Gy). Median follow-up was 66.5 months (range, 2-261 months). We noted a total of 19 (15%) recurrences. The actuarial rate of recurrence was 9.5% at 3 years, and 13.5% at 5 years postoperatively. Nine (7%) eye globes were lost, median time to enucleation was 5 years. The eye retention rate at 5 years was 92.7% and 81% at 10 years. Forty-three (34%) patients died before the end of the study, 24 (19%) of them due to metastatic disease. Metastatic death was related to: tumor size and TNM stage at presentation ( p = 0.002 vs. p = 0.0006, respectively) but not to age, gender, and plaque dosimetry. 106 Ru brachytherapy is an effective, globe sparing treatment that provides good tumor control and a high rate of survival. However, some ocular complications tend to appear late post-treatment, and therefore long-term follow-up is advised.

The follicular variant of papillary thyroid carcinoma (FVPTC) is a common subtype of papillary thyroid carcinoma. Few studies have compared the clinical behavior and treatment outcome of patients with FVPTC with the outcome of patients with pure papillary carcinoma (PTC). A retrospective study was performed to identify the influence of FVPTC compared with PTC on therapeutic variables, prognostic variables, and survival. A clinicopathologic analysis of 243 patients with papillary carcinoma was performed. One hundred forty-three tumors were PTC, and 100 tumors were FVPTC. The following variables were evaluated: age at diagnosis, tumor size, stage of tumor, treatment, capsular invasion, and survival. The median follow-up was 11.5 years. The median age was 43 years in the PTC group and 44 years in the FVPTC group. The median tumor size, disease stage, and type of initial surgery and iodine 131 ablation were similar. More patients had capsular invasion by the tumor and less metastases to cervical lymph nodes in the FVPTC group. The actuarial survival of patients age < 40 years was higher compared with the survival of patients age > 50 years in both groups. The 21-year overall actuarial survival was 82% in patients with PTC and 86% in patients with FVPTC (P value not significant). The pathologic and clinical behaviors of PTC and FVPTC were comparable. Prognostic factors, treatment, and survival also were similar. Patients in both groups must be treated identically. Copyright 2003 American Cancer Society.

Non-accidental trauma (NAT) victims account for a significant percentage of our pediatric trauma population. We sought to better understand the injury patterns and outcomes of NAT victims who were treated at our level I pediatric trauma center. Trauma registry data were used to identify NAT victims between January 2008 and December 2012. Demographic data, injury severity, hospital course, and outcomes were evaluated. One hundred and eighty-eight cases of suspected NAT were identified. Children were mostly male and white. The median age was 1.1 years; the median Injury Severity Score was 9. Traumatic brain injuries, lower extremity fractures, and skull fractures were the most common injuries. Twenty-seven per cent required medical procedures; most were performed by orthopedic surgery. Twenty-four per cent required admission to the pediatric intensive care unit. The median length of stay was two days. The mortality rate was 9.6 per cent. We generated a hot spot map of our catchment area and identified areas of our state where NAT occurs at increased rates. NAT victims sustain significant morbidity and mortality. Due to the severity of injuries, pediatric trauma surgeons should be involved in the evaluation and management of these children. Much work is needed to prevent the death and disability incurred by victims of child abuse.

Rates and characteristics of intracerebral cavernous malformations (ICMs) after cranial radiation therapy (CRT) remain poorly understood. Herein we report on ICMs detected on follow+up imaging in pediatric cancer patients who received CRT at age ≤ 18 years from 1980 to 2009. Through chart reviews (n=362) and phone interviews (n=104) of a retrospective cohort we identified 10 patients with ICMs. The median latency time for detection of ICMs after CRT was 12 years (range 1+24 years) at a median age of 21.4 years (IQR 15+28). The cumulative incidence was 3% (95% CI 1+8%) at 10 years post CRT and 14% (95% CI 7+26%) at 15 years. Three patients underwent surgical resection. Two surgical specimens were pathologically similar to sporadically occurring ICMs; one was consistent with capillary telangiectasia. ICMs are common after CRT and can show a spectrum of histological features. PMID:25122111

Adequate dietary potassium intake is associated with a reduced risk of cardiovascular and other chronic diseases. The Dietary Guidelines for Americans 2005 identifies milk and milk products as a major contributor of dietary potassium and lists dairy products, along with fruits and vegetables, as food groups to encourage. This paper further examines the impact of dairy consumption on the potassium intake of the United States (US) population. Using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2002 we determined potassium intakes for various age groups of individuals who met the recommended number of dairy servings compared to those who did not. We also examined the impact of dairy servings consumed on mean and median potassium intakes and compared intakes to the age-appropriate Adequate Intakes (AI). For all age groups, mean and median potassium intakes did not meet the respective AI. Mean potassium intakes were significantly greater in those subjects who met dairy intake recommendations compared to those who did not for all age groups. Mean and median potassium intakes increased with increasing dairy intake but were below current intake recommendations for all age groups analyzed. For adults age 19 to 50, 16.1% consumed the recommended number of dairy servings per day. For those 51 and older, 10.7% met current dairy intake recommendations. Consumption of dairy products is below current recommendations which contributes in part to suboptimal dietary potassium intakes among a large proportion of the US population. Since adequate potassium intake is associated with decreased risk of chronic disease, consumption of a variety of potassium-rich foods, including fruits, vegetables and low-fat and fat free dairy products, should continue to be encouraged.

To study the trends in incidence rate, type and surgical treatment, and patient characteristics of surgically verified endometriosis during 1987-2012. This is a register-based cohort study. We identified women receiving their first diagnosis of endometriosis in surgery from the Finnish Hospital Discharge Register (FHDR). Quality of the FHDR records was assessed bidirectionally. The age-standardized incidence rates of the first surgically verified endometriosis was assessed by calendar year. The cohort comprises 49 956 women. The quality assessment suggested the FHDR data to be of good quality. The most common diagnosis, ovarian endometriosis (46%), was associated with highest median age 38.5 years (interquartile range 31.0-44.8) and the second most common diagnosis, peritoneal endometriosis (40%), with median age 34.9 years (28.6-41.7). Between 1987 and 2012, a decrease was observed in the median age, from 38.8 (32.3-43.6) to 34.0 (28.9-41.0) years, and in the age-standardized incidence rate from 116 [95% confidence interval (CI) 112-121] to 45 (42-48) per 100 000 women. The proportion of hysterectomy as a first surgical treatment decreased from 38 to 19%, whereas that of laparoscopy increased from 42 to 73% when comparing 1987-1995 with 1996-2012. This nationwide cohort of surgically verified endometriosis showed a decrease in the incidence rate and in the patient age at the time of first diagnosis, even though the proportion of laparoscopy has increased. The number of hysterectomies has decreased. These changes are likely to reflect the evolving diagnostics, increasing awareness of endometriosis, and effective use of medical treatment before surgery. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

A multicenter study on Leigh syndrome: disease course and predictors of survival

PubMed Central

2014-01-01

Background Leigh syndrome is a progressive neurodegenerative disorder, associated with primary or secondary dysfunction of the mitochondrial oxidative phosphorylation. Despite the fact that Leigh syndrome is the most common phenotype of mitochondrial disorders in children, longitudinal natural history data is missing. This study was undertaken to assess the phenotypic and genotypic spectrum of patients with Leigh syndrome, characterise the clinical course and identify predictors of survival in a large cohort of patients. Methods This is a retrospective study of patients with Leigh syndrome that have been followed at eight centers specialising in mitochondrial diseases in Europe; Gothenburg, Rotterdam, Helsinki, Copenhagen, Stockholm, Brussels, Bergen and Oulu. Results A total of 130 patients were included (78 males; 52 females), of whom 77 patients had identified pathogenic mutations. The median age of disease onset was 7 months, with 80.8% of patients presenting by the age of 2 years. The most common clinical features were abnormal motor findings, followed by abnormal ocular findings. Epileptic seizures were reported in 40% of patients. Approximately 44% of patients experienced acute exacerbations requiring hospitalisation during the previous year, mainly due to infections. The presence of pathological signs at birth and a history of epileptic seizures were associated with higher occurrence of acute exacerbations and/or relapses. Increased lactate in the cerebrospinal fluid was significantly correlated to a more severe disease course, characterised by early onset before 6 months of age, acute exacerbations and/or relapses, as well as brainstem involvement. 39% of patients had died by the age of 21 years, at a median age of 2.4 years. Disease onset before 6 months of age, failure to thrive, brainstem lesions on neuroimaging and intensive care treatment were significantly associated with poorer survival. Conclusions This is a multicenter study performed in a large cohort of patients with Leigh syndrome. Our data help define the natural history of Leigh syndrome and identify novel predictors of disease severity and long-term prognosis. PMID:24731534

Background. Assessment of school readiness evaluates physical, social-emotional, and neuropsychological domains essential for educational success. Cognitive testing of preschool aged children with chronic liver disease may guide more timely interventions and focused efforts by health care providers. Patients and Methods. Children with chronic cholestatic liver disease diagnosed as an infant and still with their native liver (NL) and children who received a liver transplant (LT) before age of 2 years underwent testing with a battery of well-validated pediatric psychometric measures. Results. Eighteen (13 LT, 5 NL) patients (median age of 4.45 and 4.05 years, resp.) were tested. Median Full-Scale IQ was 98 (range 102-116) for LT and 116 [(range 90-106), p = 0.35, NS] for NL subjects. LT recipients had significantly greater visual based difficulties, poorer caregiver rated daily living skills ( p = 0.04), and higher levels of executive function based difficulties (e.g., inattention, inhibition). Conclusion. This pilot study highlights the risk of neuropsychological difficulties in early school age children who were under 2 years of age at time of LT. Comprehensive early school age assessment should integrate psychometric measures to identify children at greatest risk, thus allowing for proactive educational intervention.

There are limited data on the outcome of patients with thalassemia receiving HSCT from non-sibling matched family donors. Of the 341 patients with thalassemia major that underwent donor search at our center from January 2003 to December 2011, 236 (69.2%) had fully matched family donor of which 28 patients (8.2%) had non-sibling matched family donors identified. We report on seven patients with a median age of eight yr (4-21) who underwent myeloablative (n = 4) or RIC (n = 3) HSCT. The median age of the donors was 33 yr (4-47), three were parents, two first cousins, one paternal uncle, and one paternal aunt. All patients achieved primary neutrophil and platelet engraftment at a median of 18 (13-20) and 16 days (11-20), respectively. One patient developed grade II acute GVHD, and two patients developed limited chronic GVHD. One patient experienced secondary GF requiring a second transplant. At a median follow-up of 69 months (7-110), all patients are alive and thalassemia free. Our data emphasize the need for extended family HLA typing for patients with thalassemia major in regions where there is high rate of consanguinity. Transplant from non-sibling matched family donor can result in excellent outcome. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Reasons for declining kidney donors are older age, with or without, hypertension, kidney dysfunction, and diabetes. Implantation of both kidneys into a single recipient from such donors may improve their acceptability and outcome. Patients who underwent dual kidney transplantation (DKT) between June 2010 and May 2014 were identified from a prospectively maintained database. Single kidney transplantations (SKT) with matching donor criteria were also identified. Donors considered for DKT were the following: DBDs >70 years of age with diabetes and/or hypertension; DCDs >65 years of age with diabetes and/or hypertension; and DCDs >70 years of age. Over a 4-year period, 34 patients underwent adult DKT, and 51, with matching donor criteria, underwent SKT. The median estimated glomerular filtration rate (eGFR) at 12 and 36 months of DKT was 49 (range, 5-79) and 42 (range, 15-85) mL/min compared with SKT of 35 (range, 10-65) and 32 (range, 6-65), respectively. The 1-year graft survival for DKT and SKT was 88% and 96% (P = .52), and patient survival was 94% and 98%, respectively (P = .12). Median hospital stay, intensive care unit admission, and wound complications were more frequent in the DKT group. Graft function following DKT is significantly better compared with matched criteria SKT; graft and patient survival are similar. There is an increased rate of complications following DKT, with longer hospital stay and ICU admission. Copyright © 2016 Elsevier Inc. All rights reserved.

Marfan syndrome is a genetic disorder with considerable morbidity and mortality. Presently, clinicians use the 2010 revised Ghent nosology, which includes optional genetic sequencing of the FBN1 gene, to diagnose patients. So far, only a few studies based on older diagnostic criteria have reported a wide range of prevalence and incidence. Our aim was to study prevalence, incidence, and age at diagnosis in patients with Marfan syndrome. Using unique Danish patient-registries, we identified all possible Marfan syndrome patients recorded by the Danish healthcare system (1977-2014). Following, we confirmed or rejected the diagnosis according to the 2010 revised Ghent nosology. We identified a total of 1628 persons with possible Marfan syndrome. We confirmed the diagnosis in 412, whereof 46 were deceased, yielding a maximum prevalence of 6.5/100,000 at the end of 2014. The annual median incidence was 0.19/100,000 (range: 0.0-0.7) which increased significantly with an incidence rate ratio of 1.03 (95% CI: 1.02-1.04, p < 0.001). We found a median age at diagnose of 19.0 years (range: 0.0-74). The age at diagnosis increased during the study period, uninfluenced by the changes in diagnostic criteria. We found no gender differences. The increasing prevalence of Marfan syndrome during the study period is possibly due to build-up of a registry. Since early diagnosis is essential in preventing aortic events, diagnosing Marfan syndrome remains a task for both pediatricians and physicians caring for adults.

Estimation of aggregate exposure and risk requires detailed information regarding dermal contact and mouthing activity. We analyzed micro-level activity time series (MLATS) of children aged 7-12 years to quantify these contact behaviors and evaluate differences by age and gender. In all, 18 children, aged 7-12 years, were videotaped while playing outdoors. Video footage was transcribed via Virtual Timing Device (VTD) software. We calculated the hand and mouth contact frequency, hourly duration and median duration of contact with 16 object categories. Median mouthing frequencies were 12.6 events/h and 2.6 events/h for hands and non-dietary objects, respectively. Median hourly mouthing duration was 0.4 min/h and 0.1 min/h with hands and objects. Median mouthing contact duration was 1 s and 1.5 s with hands and objects, respectively. The median object contact frequency for both the hands combined was 537.3 events/h with an hourly contact duration of 81.8 min/h and a median contact duration of 3 s. There were no significant differences in the mouthing activity between genders or age groups. Female children had longer and more frequent hand contacts with several surface types. Age was negatively correlated with hand contacts of floor and wood surfaces. Contact frequencies in this study are higher than current regulatory recommendations for this age group.

To characterize a sample of Brazilian patients with maple syrup urine disease (MSUD) diagnosed between 1992 and 2011. In this retrospective study, patients were identified through a national reference laboratory for the diagnosis of MSUD and through contact with other medical genetics services across Brazil. Data were collected by means of a chart review. Eighty-three patients from 75 families were enrolled in the study (median age, 3 years; interquartile range [IQR], 0.57-7). Median age at onset of symptoms was 10 days (IQR 5-30), whereas median age at diagnosis was 60 days (IQR 29-240, p=0.001). Only three (3.6%) patients were diagnosed before the onset of clinical manifestations. A comparison between patients with (n=12) and without (n=71) an early diagnosis shows that early diagnosis is associated with the presence of positive family history and decreased prevalence of clinical manifestations at the time of diagnosis, but not with a better outcome. Overall, 98.8% of patients have some psychomotor or neurodevelopmental delay. In Brazil, patients with MSUD are usually diagnosed late and exhibit neurological involvement and poor survival even with early diagnosis. We suggest that specific public policies for diagnosis and treatment of MSUD should be developed and implemented in the country. Copyright © 2014 Sociedade Brasileira de Pediatria.

Background: Despite universal vaccination, chronic hepatitis B virus (HBV) infection remains a public health concern in North America owing to immigration. We aimed to characterize the number of people with a positive result of testing for HBV surface antigen (HBsAg) in Calgary, a large urban Canadian health care region, and to assess whether recommended laboratory tests and specialist consultation were done for those identified as HBsAg-positive. Methods: Based on laboratory and Alberta Health Services administrative data, we identified all adults (age > 18 yr) with a positive HBsAg test result from Jan. 1 to Dec. 31, 2014 within the Calgary Zone. Demographic and relevant laboratory data were extracted within 6 months of a positive HBsAg test result, and referral to hepatology (2011-2014) was identified from data on referral to a centralized clinic. Parametric and nonparametric statistical methods were used for analyses. Results: We identified 1214 HBsAg-positive people (584 women [48.1%]; median age 44 [interquartile range (IQR) 36-55] yr). A total of 1192 people (98.2%) had alanine aminotransferase testing (median level 23 [IQR 16-34] U/L; 117 [9.8%] with elevated levels), 682 (56.2%) had testing for HBV DNA (median level 2.8 [IQR 2.1-3.8] logIU/mL), 630 (51.9%) had HBV e antigen testing (negative result in 548 [87.0%]), and 145 (11.9%) had HBV e antibody testing (positive result in 111 [76.6%]). Overall, 144 people (11.9%) received anti-HBV treatment, and 390 (32.1%) were referred to a hepatologist. Interpretation: Many HBsAg-positive people in Calgary did not receive the recommended laboratory assessments. The results highlight the necessity of continual public health efforts to screen for chronic HBV infection in Canada and to ensure adequate follow-up in order to reach the World Health Organization's goal of viral hepatitis elimination by 2030.

We report a multicentre retrospective study that analysed clinical characteristics and outcomes in 117 patients with primary plasma cell leukaemia (pPCL) treated at the participating institutions between January 2006 and December 2016. The median age at the time of pPCL diagnosis was 61 years. Ninety-eight patients were treated with novel agents, with an overall response rate of 78%. Fifty-five patients (64%) patients underwent upfront autologous stem cell transplantation (ASCT). The median follow-up time was 50 months (95% confidence interval [CI] 33; 76), with a median overall survival (OS) for the entire group of 23 months (95% CI 15; 34). The median OS time in patients who underwent upfront ASCT was 35 months (95% CI 24·3; 46) as compared to 13 months (95% CI 6·3; 35·8) in patients who did not receive ASCT (P = 0·001). Multivariate analyses identified age ≥60 years, platelet count ≤100 × 10 9 /l and peripheral blood plasma cell count ≥20 × 10 9 /l as independent predictors of worse survival. The median OS in patients with 0, 1 or 2-3 of these risk factors was 46, 27 and 12 months, respectively (P < 0·001). Our findings support the use of novel agents and ASCT as frontline treatment in patients with pPCL. The constructed prognostic score should be independently validated. © 2018 John Wiley & Sons Ltd.

Growth retardation and malnutrition are major features of pediatric Crohn's disease (CD). We examined nutritional and growth parameters from diagnosis to maximal follow-up in a population-based pediatric cohort, and we determined predictive factors. A total of 261 patients (156 boys, 105 girls) with onset of CD before the age of 17 were identified from 1988 to 2004 through the EPIMAD registry (Registre des Maladies Inflammatoires Chroniques de l'Intestin) in northern France. Median age at diagnosis was 13 years (11.2-15.4) and median follow-up was 73 months (46-114). Z-scores of height/age, weight/age, and body mass index (BMI)/age were determined. Multivariate stepwise regression analysis identified predictive factors for malnutrition and growth retardation at maximal follow-up. At diagnosis, 25 children (9.5%) showed height less than -2 s.d., 70 (27%) weight less than -2 s.d., and 84 (32%) BMI less than -2 s.d. At maximal follow-up, growth retardation was present in 18 children (6.9%), whereas 40 (15%) had malnutrition. Nutritional status was more severely impaired in children with stricturing disease. Growth and nutritional retardation at diagnosis, young age, male gender, and extraintestinal manifestations at diagnosis were indicators of poor prognosis. A significant compensation was observed for weight and BMI in both genders and for height in girls. No treatment was associated with height, weight, or BMI at maximal follow-up. In our pediatric population-based study, growth retardation and severe malnutrition were still present at maximal follow-up in 6.9 and 15% of CD children, respectively. Young boys with substantial inflammatory manifestations of CD have a higher risk of subsequent growth failure, especially when growth retardation is present at diagnosis.

Maternal mortality and morbidity are major causes of death in low-resource countries, especially those in Sub-Saharan Africa. Healthcare workforce scarcities present in these locations result in poor perioperative care access and quality. These scarcities also limit the capacity for progressive development and enhancement of workforce training, and skills through continuing medical education. Newly available low-cost, in-situ simulation systems make it possible for a small cadre of trainers to use simulation to identify areas needing improvement and to rehearse best practice approaches, relevant to the context of target environments. Nurse anesthetists were recruited throughout Sierra Leone to participate in simulation-based obstetric anesthesia scenarios at the country's national referral maternity hospital. All subjects participated in a detailed computer assisted training program to familiarize themselves with the Universal Anesthesia Machine (UAM). An expert panel rated the morbidity/mortality risk of pre-identified critical incidents within the scenario via the Delphi process. Participant responses to critical incidents were observed during these scenarios. Participants had an obstetric anesthesia pretest and post-test as well as debrief sessions focused on reviewing the significance of critical incident responses observed during the scenario. 21 nurse anesthetists, (20% of anesthesia providers nationally) participated. Median age was 41 years and median experience practicing anesthesia was 3.5 years. Most participants (57.1%) were female, two-thirds (66.7%) performed obstetrics anesthesia daily but 57.1% had no experience using the UAM. During the simulation, participants were observed and assessed on critical incident responses for case preparation with a median score of 7 out of 13 points, anesthesia management with a median score of 10 out of 20 points and rapid sequence intubation with a median score of 3 out of 10 points. This study identified substantial risks to patient care and provides evidence to support the feasibility and value of in-situ simulation-based performance assessment for identifying critical gaps in safe anesthesia care in the low-resource settings. Further investigations may validate the impact and sustainability of simulation based training on skills transfer and retention among anesthesia providers low resource environments.

Cyclophosphamide (CYP) has been used for over 40 years in patients with steroid-sensitive nephrotic syndrome (NSSS) presenting frequent relapses (NSRF) or steroid dependence (NSSD). However, the long-term success of treatment with cyclophosphamide is difficult to predict. The objectives of this study are to determine long-term outcomes of cyclophosphamide and identify the factors associated with sustained remission. We retrospectively studied the data from 50 patients with idiopathic nephrotic syndrome, treated by oral cyclophosphamide and followed at service of pediatric for more than 8 years for idiopathic nephrotic syndrome and related factors for survival without relapse were evaluated by univariate analysis. The median age at the time of diagnosis was 4.3 years, and median follow-up time was 1.7 years with the median of 8 years at the first use of CYC. Patients had received a median cumulative dose of 168mg/kg. At the end of follow-up, 38% of patients entered into remission after using CYC while 62% failed to respond and further relapses then occur. The median time of stopping corticosteroid therapy was three month. The survival without relapse was respectively 56% (28 patients), 52% (26 patients), 48% (24 patients), and 38% (19 patients), at 6 months, one year, two years and more than two years. In univariate analysis, the survival without relapse was related to the age at the moment of starting the therapy par CYC (the median was 5 months for an age < 8 years and 41 months for an age≥8 years; P=0.049), the type of nephrotic syndrome [36 months for SNRF, 4 months for NSSD and nephrothic syndrome steroid resistant (NSSR); P=0.068], and the histological lesion (6 months for diffuse mesangial proliferation, 2 months for segmental glomerulosclerosis; P=0.009). The age at the moment of diagnosis, the sex and the cumulative dose of CYC did not have significant influence. The results presented in this study suggest the use of oral cyclophosphamide for short period remain second line effective therapy. Further well-designed trials are required to evaluate the efficacy of other steroid-sparing agents. Copyright © 2017 Société francophone de néphrologie, dialyse et transplantation.

A retrospective study of 354 human immunodeficiency virus (HIV)-infected patients identified a subgroup of 27 children with seizures (7.6%, 95% confidence interval: 5.1%-10.9%). Of the total group, 13% (n = 46) had identifiable neurologic deficits and 30% (n = 107) had developmental delay. Both observations were significantly more frequent in the subgroup of patients with seizures (P < .001). The median age of patients with seizures was 20 months (range, 8-87 months) and the median baseline CD4 percentage was 13.5% (interquartile range, 8%-23%). Seizures were treated with sodium valproate (n = 11), phenobarbital (n = 3), diazepam (n = 2), lamotrigine (n = 1), and carbamazepine (n = 1). Combination therapy was required for 5 children. Suboptimal valproic acid levels were recorded for 3 patients. When resources are available, antiepileptic drug level monitoring is advised for children who require both antiepileptic and antiretroviral medications to facilitate optimal seizure management.

To describe tachyphylaxis to intravitreal bevacizumab (IVB) in patients with exudative age-related macular degeneration (AMD). We retrospectively reviewed the records of 59 consecutive patients treated with IVB at the National Eye Institute over a 14-month period and identified cases demonstrating loss of treatment efficacy as revealed by spectral domain optical coherence tomography. We defined tachyphylaxis as a loss of therapeutic response to IVB 28 +/- 7 days after administration in an eye that had previously demonstrated a therapeutic response in the same time interval. Five patients (six eyes) were identified as developing tachyphylaxis after repeated treatment with IVB. High-dose IVB (2.50 mg) did not restore therapeutic response in these patients. Bilateral tachyphylaxis to IVB was seen after an episode of unilateral postinjection anterior uveitis. After the first treatment of IVB, the median time taken to develop tachyphylaxis was 100 weeks (range: 31-128 weeks), and the median number of IVB treatments to the development of tachyphylaxis was 8 treatments (range: 5-10 treatments). Tachyphylaxis can occur after long-term intravitreal use of bevacizumab in patients with AMD. The precise mechanism of tachyphylaxis is unclear, but both local and/or systemic factors may be involved.

Background: Early menopause, defined as the cessation of ovarian function before the age of 45 y, affects ∼10% of women and is associated with higher risk of cardiovascular disease, osteoporosis, and other conditions. Few modifiable risk factors for early menopause have been identified, but emerging data suggest that high vitamin D intake may reduce risk. Objective: We evaluated how intakes of vitamin D and calcium are associated with the incidence of early menopause in the prospective Nurses' Health Study II (NHS2). Design: Intakes of vitamin D and calcium from foods and supplements were measured every 4 y with the use of a food-frequency questionnaire. Cases of incident early menopause were identified from all participants who were premenopausal at baseline in 1991; over 1.13 million person-years, 2041 women reported having natural menopause before the age of 45 y. We used Cox proportional hazards regression to evaluate relations between intakes of vitamin D and calcium and incident early menopause while accounting for potential confounding factors. Results: After adjustment for age, smoking, and other factors, women with the highest intake of dietary vitamin D (quintile median: 528 IU/d) had a significant 17% lower risk of early menopause than women with the lowest intake [quintile median: 148 IU/d; HR: 0.83 (95% CI: 0.72, 0.95); P -trend = 0.03]. Dietary calcium intake in the highest quintile (median: 1246 mg/d) compared with the lowest (median: 556 mg/d) was associated with a borderline significantly lower risk of early menopause (HR: 0.87; 95% CI: 0.76, 1.00; P -trend = 0.03). Associations were stronger for vitamin D and calcium from dairy sources than from nondairy dietary sources, whereas high supplement use was not associated with lower risk. Conclusions: Findings suggest that high intakes of dietary vitamin D and calcium may be modestly associated with a lower risk of early menopause. Further studies evaluating 25-hydroxyvitamin D concentrations, other dairy constituents, and early menopause are warranted. © 2017 American Society for Nutrition.

Variables included age, gender, original training department, highest degree, rank, endowed chair assignment, National Institutes of Health (NIH) funding, and Hirsch index (H-index). Data were gathered from online sources such as departmental websites, NIH RePORTER, and Scopus. Results: There were a total of 87 PD. The median age was 48, and 14 (16%) were MD/PhD. A total of 21 (24%) weremore » female, and rank was relatively equally distributed above instructor. Of the 26 professors, at least 7 (27%) were female. At least 24 (28%) were working at the institution from which they had received their training. A total of 6 individuals held endowed chairs. Only 2 PD had active NIH funding in 2012. The median H-index was 12 (range, 0-51) but the index dropped to 9 (range, 0-38) when those who served as both PD and chair were removed from the group. A total of 76 chairs were identified at the time of the study. The median age was 55, and 9 (12%) were MD/PhD. A total of 7 (9%) of the chairs were female, and rank was professor for all with the exception of 1 who was listed as “Head” and was an associate professor. Of the 76 chairs, at least 10 (13%) were working at the institution from which they received their training. There were a total of 21 individuals with endowed chairs. A total of 13 (17%) had NIH funding in 2012. The median H-index was 29 (range, 3-60). Conclusions: These data provide benchmarks for individuals and departments evaluating leadership positions in the field of academic radiation oncology. Such data are useful for evaluating leadership trends over time and comparing academic radiation oncology with other specialties.« less

In the CORAL study, 255 chemosensitive relapses with diffuse large B-cell lymphoma (DLBCL) were consolidated with autologous stem cell transplantation (ASCT), and 75 of them relapsed thereafter. The median time between ASCT and progression was 7.1 months. The median age was 56.1 years; tertiary International Prognosis Index (tIPI) observed at relapse was 0-2 in 71.6% of the patients and >2 in 28.4%. The overall response rate to third-line chemotherapy was 44%. The median overall survival (OS) was 10.0 months (median follow-up: 32.8 months). Thirteen patients received an allogeneic SCT, and three a second ASCT. The median OS was shorter among patients who relapsed <6 months (5.7 months) compared with those relapsing ⩾12 months after ASCT (12.6 months, P=0.0221). The median OS in patients achieving CR, PR or no response after the third-line regimen was 37.7 (P<0.0001), 10.0 (P=0.03) and 6.3 months, respectively. The median OS varied according to tIPI: 0-2: 12.6 months and >2: 5.3 months (P=0.0007). In multivariate analysis, tIPI >2, achievement of response and remission lasting <6 months predicted the OS. This report identifies the prognostic factors for DLBCL relapsing after ASCT and thus helps to select patients for experimental therapy.

i) To establish the seroprevalence of Feline Coronavirus (FCoV) infection in two defined groups of cats in Sydney: owned and feral cats; ii) to identify factors associated with an increased risk of infection with FCoV; and iii) to establish the seroprevalence and FCoV antibody titres of owned cats with immunohistochemically confirmed feline infectious peritonitis (FIP). Prospective multi-institutional cross sectional study. Procedure Serum samples from owned cats presented to three inner city veterinary clinics in Sydney and feral cats from a colony in South Western Sydney over an 11-month period were tested for FCoV antibodies using the Immunocomb test kit. The relationship between serological score and six major factors (breed, age, gender, number of cats per household, living environment and health status) in the owned cat sample population was analysed and compared to cats with FIR RESULTS: The seroprevalence of FCoV infection in the sample population of owned and feral cats was 34% and 0%, respectively. The median Immunocomb scores of DSH, Persian, Siamese and Devon Rex cats were significantly lower than that of Burmese, BSH, Abyssinian, Birman, Ragdoll and Russian Blue. The median lmmunocomb score of pedigree cats less than 2 years-of-age was significantly higher than for pedigree cats greater than 2 years-of-age. This distinction was not evident in DSH cats in these age groups. The number of cats per household at the time of blood collection had a strong positive association with Immunocomb score. The median Immunocomb score of cats with immunohistochemically confirmed FIP was significantly higher than cats in the sample population of owned cats but there was sufficient overlap between these two groups to make definitive diagnosis of FIP by serology impossible. This represents the first seroprevalence study of FCoV in Australia. The major determinants of antibody score of owned cats identified in this study were breed, age and the number of cats per household. The significant relationship between the breed of the cat and the FCoV antibody titre further supports the notion, proposed previously by the authors, that breed related differences exist in the immunological response to FCoV infection.

Although macroscopic haematuria during the month following transurethral resection of the prostate, due to sloughing of necrotic tissue, is a phenomenon well known to urologists since introduction of endoscopic resection, its pathophysiological and epidemiological characteristics are poorly defined. The objective of this retrospective study was to define the incidence of serious macroscopic haematuria after transurethral resection of the prostate (TURP) and to identify the risk factors for macroscopic haematuria. The hospital database was used to identify patients treated by TURP between 1997 and 2004 and rehospitalized during the 31 days following the procedure. Files of patients presenting with haematuria and bladder clots were selected and analysed. Ten of a series of 624 patients undergoing TURP were hospitalised for bladder clots and their case files were analysed: median age: 72 years, median duration of TURP: 45 min and median weight of resection: 12 g. The operators' experience and the duration of post-TURP catheterization were not informative. In 2 cases, prostate cancer was diagnosed after analysis of resection chips. Two patients were treated by anticoagulants. Patients were essentially rehospitalized during the 2nd week (median: 11th day). A bladder catheter for was inserted for lavage in each case. No patient required reoperation or removal of clots under general anaesthesia. Two patients were transfused. We did not identify any risk factor for sloughing leading to macroscopic haematuria during the month following TURP. Macroscopic haematuria justifying rehospitalization is a rare event. However, in view of this low incidence, optimal analysis could only be performed in the context of a national prospective register.

Malaria control policies have not fully achieved the expected results due to little consideration of cultural aspects, among other factors. To explore the cultural domains pertaining to this disease in an endemic Colombian population, in order to both design and implement effective action plans. A convenience sampling was conducted to select inhabitants from 12 villages in Tierralta, Córdoba. In order to generate free-lists, participants were asked about their communities' health problems, causes of malaria, control measures and those responsible for malaria control. Smith's indexes were calculated for each item answered. Between 30 and 38 individuals per village participated in the study (N=401). The mean age was 40.24 years (standard deviation (SD)=14.22) and women were 45.39% of the total. Participants recognized malaria and respiratory infections as the primary health problems in the community (median Smith's indexes: 0.83 and 0.63, respectively). A lack of environmental interventions was identified as the main determinant of malaria (median Smith's index: 0.65). Finally, the health care center (median Smith's index: 0.71) and health professionals (median Smith's index: 0.52) were identified as those most responsible for malaria control. The design of programs to reduce the impact of malaria requires developing interventions or initiatives that are adapted to the community's needs, demands and available resources. Free-listing is proposed as an effective tool to collect information about cultural domains related to health.

Surprisingly few studies have examined weight change in hypothyroid patients after initiation of levothyroxine (LT4) therapy. Our study aimed to investigate weight change after initiation of LT4 treatment for primary hypothyroidism. Using electronic medical records from Boston Medical Center, Boston, Massachusetts, we performed a retrospective cohort study between January 1, 2003, and February 1, 2011. Adults ≥18 years of age with newly diagnosed primary hypothyroidism with an initial thyroid-stimulating hormone (TSH) level ≥10 mIU/L were identified. Patients with postsurgical hypothyroidism, thyroid cancer, and a history of radioactive iodine or head/neck irradiation, congestive heart failure, anorexia nervosa, end-stage renal disease, cirrhosis, pregnancy, or use of prescription weight-loss medications were excluded. TSH and weight at diagnosis and up to 24 months after LT4 initiation were collected. Weight change was assessed at the first posttreatment serum TSH level <5 mIU/L. A total of 101 patients (mean age, 48 ± 15 years; 71% women) were included. Initial median TSH was 18.3 mIU/L (range, 10.1 to 710.5 mIU/L) and initial median weight was 79.6 kg (range 41.5 to 167.5 kg). Posttreatment median TSH level was 2.3 mIU/L (range, 0.04 to 5 mIU/L), and weight change at a median of 5 months (range, 1.1 to 25.6 months) was -0.1 kg (range, -20.6 to 7.7 kg). Initial median body mass index (BMI) of 95 of the patients was 29.3 kg/m2 (range, 19.5 to 56.1 kg/m2), and the median change in BMI was -0.1 kg/m2 (range, -7.1 to 3.3 kg/m2). Only 52% of patients lost weight, with a mean weight loss of 3.8 ± 4.4 kg. Gender, race, education, insurance type, age, initial TSH level, time to normalization of TSH, and initial weight were not associated with changes in weight or BMI. Contrary to popular belief, our study of 101 patients with primary hypothyroidism showed that no significant weight change occurs after initiation of LT4 treatment.

The present study described a group A rotavirus (RVA) outbreak in an age-care facility in Brazil, using epidemiologic and molecular diagnostic methods. A descriptive clinical, epidemiological and environmental investigation was conducted. Stool samples were collected and screened for RVA, Norovirus (NoV), Enteric Adenovirus 40/41 (AdV 40/41) and Astrovirus (AstV) using ELISA, RT-PCR, qRT-PCR, electron microscopy and sequencing methods. Outbreak occurred during 26th-29th October, 2015; 28 individuals affected (22 residents; 6 staff). The attack rate was 25.9% and 8.5% among residents (median-age: 85.5 years) and staff (median-age: 28 years), respectively. Female staff was identified as the index case. RVA G2P[4] genotype was detected in 87.5% (7/8). Genetic analysis demonstrated that the outbreak involved one single strain, suggesting a common-source infection. RVA should be considered during outbreaks investigations in residential facilities, and raise the question if the current licensed RVA vaccines for children could also be helpful for the elderly.

This study presents the demographics, clinical spectrum, and outcome of patients with congenital factor VII (FVII) deficiency at a tertiary care center over a period of 12 years. Of the 49 patients, 27 (55%) patients were males. Consanguinity was found in 92% of the patients. The median age of symptom onset was 2.4 (interquartile range [IQR]: 1.1-6.5) years with a median age of 5.8 (IQR: 3.1-10) years at diagnosis. Life-threatening complications like intracranial bleeding (ICB) and intra-abdominal bleeding (IAB) were observed in 8 (16.4%) patients. We found that 11 (55%) of the 20 patients with FVII coagulant activity (FVIIc) <1% were either asymptomatic or showed mild phenotype. In contrast, 9 (53%) of the 17 patients with FVIIc >5% were affected by severe symptoms. Age <1 year was the only identified risk factor associated with development of life-threatening bleeding episodes (P = .042; odds ratio 6.46). Overall, 4 (8.2%) died as a consequence of ICB (3 patients) and IAB (1 patient). © The Author(s) 2013.

The aim of this study was to measure the prevalence of potentially inappropriate medications (PIMs) by using the EU(7)-PIM list, STOPP (Screening Tool of Older Persons' potentially inappropriate Prescriptions) version 2 criteria and the new comprehensive protocol. This prospective study involved a sample of 276 consecutive elderly patients discharged from the university teaching hospital. Age, gender, diagnoses, medication history and medicines at discharge were recorded. The main outcome measure was the prevalence of PIMs according to each set of criteria: EU(7)-PIM list, STOPP version 2 criteria and comprehensive protocol. The median patient age (range) was 74 (65-92) years. The median number of prescribed medications was 7 (1-17). STOPP identified 393 PIMs affecting 190 patients (69%), EU(7)-PIM list identified 330 PIMs in 184 patients (66.7%) whilst the comprehensive protocol identified 134 PIMs in 102 patients (37%). STOPP version 2 criteria identified significantly more PIMs per patient than the other two protocols (p < 0.001). Gender (p = 0.002), glomerular filtration rate (p = 0.039) and number of comorbidities (p = 0.001) were associated with the proportion of PIMs for the STOPP version 2 criteria only. A very high PIM prevalence at discharge was reported suggesting the urgent need for actions to reduce them. STOPP version 2 criteria identified significantly more PIMs than the EU(7)-PIM list and the comprehensive protocol and was found as a more sensitive tool for PIM detection.

Gorlin syndrome is an autosomal dominant disorder, characterized by multiple early-onset basal cell carcinomas (BCCs) and jaw keratocysts. Through association studies in cohorts of sporadic BCC, nine genetic variants have previously been identified to increase the risk of BCC. The nine SNPs were genotyped by Taqman allelic discrimination in 125 individuals with Gorlin syndrome. Kaplan-Meier survival curves and Cox proportional-Hazard regression analysis were applied to determine the association between genotypes and age of first BCC in individuals with Gorlin syndrome. The p.(Arg151Cys) variant in MC1R (rs1805007) was associated with an earlier median age of onset of BCC of 27 years (95% CI: 20-34) compared with 34 years (95% CI: 30-40) for wild-type individuals (hazard ratio (HR)=1.64, 95% CI: 1.04-2.58, P=0.034). The risk allele of the variant at the chromosome 5p15 locus encompassing TERT-CLPTM1L (rs401681) was also associated with an earlier median onset of BCC, 31 years (95% CI: 28-37) compared with 41 years (95% CI: 32-48, HR=1.44, 95% CI: 1.08-1.93, P=0.014). In individuals with a risk allele at either rs1805007 or rs401681 the median time to BCC was 31 years of age (95% CI: 28-34) compared with 44 years of age (95% CI: 38-53) in wild-type individuals (HR=2.48, 95% CI: 1.47-4.17, P=0.0002). Our findings may have implications for future personalized risk estimates and BCC screening strategies in individuals with Gorlin syndrome.

Does the Age of Donor Kidneys Affect Nocturnal Polyuria in Patients With Successful Real Transplantation?

We investigated whether the age of donor kidneys influences the incidence of nocturnal polyuria in patients with successful renal transplantation (RTX). Eighty-five patients (45 men and 40 women) undergoing RTX (median age, 47 years) were included in this study. Twenty-four-hour bladder diaries were kept for 3 days, and nocturnal polyuria was defined as a nocturnal polyuria index (nocturnal urine volume/24-hour urine volume) of >0.33. Risk factors for nocturnal polyuria were analyzed in patients with RTX by means of the Mann-Whitney U test, χ 2 test, and a logistic regression analysis. End-stage renal disease (ESRD) developed from diabetes mellitus in 16 patients (19%). Sixty-five patients (76%) received pre-transplant dialysis, with a median duration of 5 years. The median serum creatinine level and body mass index at the most recent visit were 1.2 mg/dL and 21.2 kg/m 2 , respectively. On the basis of the 24-hour bladder diaries, nocturnal polyuria was identified in 48 patients (56%). A logistic regression analysis revealed that diabetes mellitus as the original disease for ESRD was the only risk factor for nocturnal polyuria (odds ratio, 8.95; 95% confidence interval, 2.01-65.3; P = .0028). The age of donor kidneys at examination did not affect the incidence of nocturnal polyuria (P = .9402). Nocturnal polyuria was not uncommon in patients with successful RTX. Diabetes mellitus as the original disease for ESRD was the only risk factor for nocturnal polyuria, whereas the age of donor kidneys at examination did not affect the incidence of nocturnal polyuria. Thus, nocturnal polyuria is caused by recipient factors but not donor factors. Copyright © 2016 Elsevier Inc. All rights reserved.

SUMMARY SETTING Kisenyi slum in peri-urban Kampala, Uganda. OBJECTIVES Using chronic cough (≥2 weeks) inquiry as a screening tool to identify undetected smear-positive tuberculosis (TB) cases and to describe the characteristics of smear-positive TB cases detected by active case finding. DESIGN A house-to-house survey was conducted in five randomly selected villages in Kampala between June and August 2005. A sample of households was visited; adults aged ≥15 years were consecutively interviewed to identify those with chronic cough. Three sputum specimens were collected and examined by smear microscopy. RESULTS Among 930 individuals, we identified 189 (20%) chronic coughers. Of these, we found 33 (18%) undiagnosed smear-positive cases. The newly detected cases had an even sex distribution (P = 0.47), a median age of 30 years, a median cough duration of 1 month and 55% had acid-fast bacilli 1+ sputum smear grade. CONCLUSION These findings suggest that active case finding could supplement DOTS to yield additional smear-positive TB cases, lead to early diagnosis and thus shorten the duration of infectiousness before effective chemotherapy is initiated. In communities such as Kisenyi, this is a feasible strategy that may prove useful for TB control, but its cost-effectiveness needs to be evaluated. Early health care seeking for cough should be emphasized. PMID:19335958

Stricturing is a common complication of Crohn's disease. Endoscopic balloon dilatation (EBD) offers a valuable alternative to surgical intervention, but there are limited data on factors influencing its safety and efficacy. A multicenter retrospective audit across 4 U.K. teaching hospitals was performed on the use of EBD for Crohn's strictures between 1998 and 2011. Demographics, smoking status, medications, C-reactive protein, endoscopic findings, and subsequent surgery at follow-up were recorded. Success of EBD was defined as symptomatic improvement without the need for surgery at follow-up. Seventy-nine patients (47 women; median age, 48 yr) were identified for this study. Forty-eight (61%) patients had ileocolonic anastomotic strictures, whereas the rest had de novo strictures. In total, 191 EBDs (range, 1-11; median 2) were carried out on 93 strictures (range, 1-5; median 1) over a median duration of 12 months (range, 1-84). There were no serious adverse events. Success at index EBD was 34%, with a further 43% achieving long-term benefit from additional EBDs. Eighteen (23%) patients required surgery. Time to surgery after the first EDB was 2.6 to 71.1 months (median, 12.8 mo). Longer Crohn's disease duration (P = 0.03) and high C-reactive protein (P = 0.008) were associated with an increased need for subsequent surgery. EBD was safe and effective in achieving long-term symptom improvement and avoidance of surgery in most patients. Prospective controlled trials are needed to evaluate the effect of other factors, including Crohn's disease phenotype, and the role of concomitant medication to identify those best suited to EBD.

While pediatric diffuse intrinsic pontine gliomas (DIPG) remain fatal, recent data have shown subgroups with distinct molecular biology and clinical behavior. We hypothesized that diffusion-weighted MRI can be used as a prognostic marker to stratify DIPG subsets with distinct clinical behavior. Apparent diffusion coefficient (ADC) values derived from diffusion-weighted MRI were computed in 20 consecutive children with treatment-naïve DIPG tumors. The median ADC for the cohort was used to stratify the tumors into low and high ADC groups. Survival, gender, therapy, and potential steroid effects were compared between the ADC groups. Median age at diagnosis was 6.6 (range 2.3-13.2) years, with median follow-up seven (range 1-36) months. There were 14 boys and six girls. Seventeen patients received radiotherapy, five received chemotherapy, and six underwent cerebrospinal fluid diversion. The median ADC of 1,295 × 10(-6) mm(2)/s for the cohort partitioned tumors into low or high diffusion groups, which had distinct median survivals of 3 and 13 months, respectively (log-rank p < 0.001). Low ADC tumors were found only in boys, whereas high ADC tumors were found in both boys and girls. Available tissue specimens in three low ADC tumors demonstrated high-grade histology, whereas one high ADC tumor demonstrated low-grade histology with a histone H3.1 K27M mutation and high-grade metastatic lesion at autopsy. ADC derived from diffusion-weighted MRI may identify prognostically distinct subgroups of pediatric DIPG.

Introduction Sarcoidosis is a multi-organ system granulomatous disease of unknown origin with an incidence of 1–40/100,000. Though pulmonary manifestations are predominant, ocular sarcoidosis (OS) affects 25–50% of patients with sarcoidosis and can lead to blindness. Methods A retrospective, single-center chart review of sarcoidosis cases investigated variables associated with the development of OS. Inclusion criteria were biopsy-proven sarcoidosis, disease duration greater than 1 year, documented smoking status on chart review and documentation of sarcoid-related eye disease. Multivariate analysis identified independent risk factors for OS. Results Of 269 charts reviewed, 109 patients met inclusion criteria. The OS group had a significantly higher proportion of smokers (71.4%) than without OS (42.0%, p=0.027) with no difference (p=0.61) in median number of pack years. Male sex was significantly higher in the OS group (57.1% versus 26.1%, p=0.009). Median duration of sarcoidosis was higher in the OS group (10 versus 4 years, p=0.031). Multivariate regression identified tobacco exposure (OR=5.25, p=0.007, 95% CI 1.58–17.41), male sex (OR=7.48, p=0.002, 95% CI 2.15–26.01), and age (OR=1.114, p=0.002, 95% CI 1.04–1.19) as concomitant risk factors for the development of OS. Conclusion To date, there are few dedicated investigations of risk factors for OS, especially smoking. This investigation identified male sex, age, and tobacco exposure as independent risk factors for OS. Though disease duration did not withstand regression analysis in this moderately sized group, age at chart review suggests screening for OS should not remit but rather intensify in aging patients with sarcoidosis.

APC gene mutations in individuals with possible attenuated familial adenomatous polyposis coli

DOE Office of Scientific and Technical Information (OSTI.GOV)

Frayling, J.M.; Talbot, J.; Harocopos, C.A.

Spirio et al. have described an attenuated form of familial adenomatous polyposis (FAP) termed AAPC, where affected individuals have been found to have mutations in exons 3 & 4 of the APC gene. AAPC expression within a family appears to be extremely variable and can overlap clinically with FAP, giving rise to between zero and a few hundred adenomas. The phenotypic range associated with AAPC mutations is undefined and the frequency in the population of such alleles of the APC gene is unknown. In addition, it is as yet unclear how many cases of sporadic colorectal adenomas might have AAPC.more » In order to address this we have identified 110 individuals having a phenotype compatible with a diagnosis of AAPC, in three groups: (1) 30 individuals (15m, 15f; median age = 55y, range 8-71y) with some or all of the following: colonic adenomas (28 cases); colorectal cancer (12 cases); extra-colonic features of FAP, either desmoid tumours (4 cases, including 2 without colonic adenomas) or sebaceous cysts (2 cases). Sixteen cases had a family history of adenomas/colorectal cancer/extra-colonic features of FAP. (2) 16 individuals (10m, 6f) from the St. Mark`s Polyposis Registry, diagnosed with FAP (including a family history), who had unusually few adenomas (median = 200) at colectomy (median age = 43y, range 17-62y). (3) 64 individuals (43m, 21f) from the St. Mark`s Hospital Adenoma Follow-up Study who either had >4 adenomas at presentation (median total adenomas = 9), or >4 adenomas detected during follow-up (median total adenomas = 9). Genomic DNA was obtained from these individuals and exons 1-4 of the APC gene were amplified by PCR. Chemical cleavage of mismatch was used to screen for mutations, followed by sequencing if variant bands were found. Germ-line mutations have been identified in exons 3 and 4 in a proportion of these individuals, thus extending the clinical spectrum of phenotypes associated with mutations in this region of the APC gene.« less

Approximately 150-250 migrants die each year while attempting to cross the border from Mexico to the Southwest United States. Many border crossers survive the journey, but some develop life-threatening medical complications. Such complications have been subject to little formal analysis. We sought to determine the causes of critical illness in this population and to analyze the hospital course and outcomes of these patients. We retrospectively identified border crossers admitted to the intensive care units (ICUs) of two major teaching hospitals in southern Arizona. We recorded admitting diagnoses, severity of illness, length of stay, resource use, discharge diagnoses, and mortality. Our investigation identified 55 admissions to adult ICUs between January 1, 2010 and December 31, 2012. The median age of patients was 27 years. The median hospital length of stay was 7 days, with a median ICU length of stay of 3 days. The median temperature on arrival to the emergency department was 36.8°C. The most common admission diagnoses included trauma (40), rhabdomyolysis (27), acute liver injury (25), dehydration (24), acute kidney injury (19), and encephalopathy (17). Thirteen patients presented with respiratory failure, six patients with severe sepsis, and two with septic shock. A total of 19 patients required ventilator support during their hospital stay, and 30 required at least one surgical intervention. One patient required renal replacement therapy. The median Acute Physiology and Chronic Health Evaluation II score was 6. All but one patient survived to discharge from the hospital. Border crossers are a unique population of young individuals exposed to high temperatures and extreme conditions. Our review of border crosser admissions showed that most patients demonstrated signs of dehydration and leukocytosis, despite a normal median temperature. The median ICU stay was short, despite a high number of patients requiring ventilator support and surgical intervention. Only one death occurred in this cohort.

Background Animal tungiasis is believed to increase the prevalence and parasite burden in humans. Animal reservoirs of Tunga penetrans differ among endemic areas and their role in the epidemiology of tungiasis had never been investigated in Uganda. Methods and Findings To identify the major animal reservoirs of Tunga penetrans and their relative importance in the transmission of tungiasis in Uganda, a cross sectional study was conducted in animal rearing households in 10 endemic villages in Bugiri District. T. penetrans infections were detected in pigs, dogs, goats and a cat. The prevalences of households with tungiasis ranged from 0% to 71.4% (median 22.2) for animals and from 5 to 71.4% (median 27.8%) for humans. The prevalence of human tungiasis also varied among the population of the villages (median 7%, range 1.3–37.3%). Pig infections had the widest distribution (nine out of 10 villages) and highest prevalence (median 16.2%, range 0–64.1%). Pigs also had a higher number of embedded sand fleas than all other species combined (p<0.0001). Dog tungiasis occurred in five out of 10 villages with low prevalences (median of 2%, range 0–26.9%). Only two goats and a single cat had tungiasis. Prevalences of animal and human tungiasis correlated at both village (rho = 0.89, p = 0.0005) and household (rho = 0.4, p<0.0001) levels. The median number of lesions in household animals correlated with the median intensity of infection in children three to eight years of age (rho = 0.47, p<0.0001). Animal tungiasis increased the odds of occurrence of human cases in households six fold (OR = 6.1, 95% CI 3.3–11.4, p<0.0001). Conclusion Animal and human tungiasis were closely associated and pigs were identified as the most important animal hosts of T. penetrans. Effective tungiasis control should follow One Health principles and integrate ectoparasites control in animals. PMID:26473360

Prescription of a high-energy, high-fat diet is a mainstay of nutrition management in cystic fibrosis (CF). However, families may be relying on energy-dense, nutrient-poor (EDNP) foods rather than nutrient-dense (ND) foods to meet dietary targets. We aimed to evaluate the relative contribution of EDNP and ND foods to the usual diets of children with CF and identify sociodemographic factors associated with higher EDNP intakes. This is a cross-sectional comparison of children with CF aged 2-18 years and age- and gender-matched controls. Dietary intake was assessed using the Australian Child and Adolescent Eating Survey (ACAES) food frequency questionnaire. Children with CF (n = 80: 37 males; mean age 9.3 years) consumed significantly more EDNP foods than controls (mean age 9.8 years) in terms of both total energy (median [IQR]: 1301 kcal/day (843-1860) vs. 686 kcal/day (480-1032); p < 0.0001), and as a proportion of energy intake (median [IQR]: 44% (34-51) vs. 31% (24-43); p < 0.0001). Although children with CF met their estimated energy requirements (median [IQR]: 158% (124-187) vs. 112% (90-137); p < 0.0001) and their diets were high in fat (median [IQR]: 38% (35-41) vs. 34% (32-36); p < 0.0001), this was largely attributable to EDNP foods. High EDNP intakes (≥10 serves/day) were associated with socioeconomic disadvantage (p = 0.01) and rural residential location (p = 0.03). The energy- and fat-dense CF diet is primarily achieved by overconsumption of EDNP foods, rather than ND sources. This dietary pattern may not be optimal for the future health of children with CF, who are now expected to survive well into adulthood. Copyright © 2018 European Cystic Fibrosis Society.

To present the results of feminising genitoplasty done in female patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Case series. A tertiary referral centre in Hong Kong. Female patients with congenital adrenal hyperplasia undergoing corrective surgery for virilisation between 1993 and 2012. The operative result was judged with a scoring system (1-3) for four areas: appearance of clitoris, labia and vagina, plus requirement for revision surgery. A total of 23 female patients with congenital adrenal hyperplasia with a median age of 17.5 (range, 1.5-33.8) years were identified. Of these individuals, 17 presented in the neonatal period and early infancy, of which four had an additional salt-losing crisis. Six patients-including four migrants from mainland China-were late presenters at a median age of 2 (range, 0.5-14) years. Twenty-two patients had corrective surgery at a median age of 2 (range, 1-14) years. Clitoral reduction was performed in all, and further surgery in 21 patients. The additional surgery was flap vaginoplasty in 10 patients, a modified Passerini procedure in six, and a labial reconstruction in five; one patient with prominent clitoris was for observation only. Minor revision surgery (eg mucosal trimming) was required in three patients; a revision vaginoplasty was done in one individual. Of the 23 patients, 18 (78%) with a median age of 20 (range, 9.3-33.8) years participated in the outcome evaluation: a 'good' outcome (4 points) was seen in 12 patients and a 'satisfactory' (5-9 points) result in five patients. Nearly three quarters of our cohort (n=17) presented with classic virilising form of 21-hydroxylase deficiency. Only four (25%) patients experienced a salt-losing crisis. Female gender assignment at birth was maintained for all individuals in this group. 'Good' and 'satisfactory' outcomes of surgery were reported in nearly all participants.

Time to symptom resolution, return to school, and return to play after a sport-related concussion in children and adolescents (8-17 years of age) was examined using a retrospective cohort design. A total of 198 patients aged 8 to 17 years were included, with a mean age of 13.5 years (SD = 2.2). Patients aged 8 to 12 years were symptom-free in a median of 12.0 (range 1-60) days whereas 13- to 17-year olds were symptom-free in a median of 14.0 (range 1-300) days (P = .04). Patients aged 8 to 12 years returned to learn in a median of 4.0 (range 0-30) days compared with 2.5 (range 0-55.0) days in 13- to 17-year-olds (P = .86). Patients aged 8 to 12 years returned to play in a median of 14.0 (range 4-75) days compared with a median of 19.5 (range 5-75) days in 13- to 17-year-olds (P = .06). These results indicate that children and adolescents generally take 2 to 4 weeks to recover from a sport-related concussion. © The Author(s) 2015.

Our objective was to analyze the long-term oncologic outcomes of fertility-preserving hormonal treatment with medroxyprogesterone acetate (MPA) in patients with APA. In a retrospective chart review, we identified patients with APA who were treated with MPA for fertility preservation at our hospital between 2001 and 2011. Eighteen patients with histologically diagnosed APA were identified. Clinical data including treatment, obstetrical, and oncologic outcomes were recorded. The mean observation period was 77.6 months (median 73.5, range 22-142), and the mean age was 33.6 years. Four patients also developed well-differentiated endometrial carcinoma. After the treatment, 14 patients (77.8 %) achieved either a complete response or partial response. Eight patients experienced recurrence, while four experienced persistent disease. Ten patients (55.6 %) eventually underwent hysterectomy. The median time to hysterectomy was 40.3 months (range 24-68). Nine patients progressed to endometrial cancer, and one experienced persistent APA. Among younger patients (<35 years of age), four out of five patients who were married could have children. Seven patients (38.9 %) showed no evidence of the disease during the observation period (median 60 months, range 22-117 months). No one died because of the disease during the observation period. MPA yields a high response rate in APA, and if only younger patients are considered, a favorable pregnancy rate can be obtained. However, because recurrence rate is high, long-term follow-up under supervision of a trained gynecologic oncologist is required. To confirm MPA's utility, multi-center collaboration would be warranted.

The 2008 World Health Organization (WHO) criteria were used to identify 88 consecutive Mayo Clinic patients with 'myelodysplastic syndrome with isolated del(5q)' (median age 74 years; 60 females). In all, 60 (68%) patients were followed up to the time of their death. Overall median survival was 66 months; leukemic transformation was documented in five (5.7%) cases. Multivariable analysis identified age >or=70 years (P=0.01), transfusion need at diagnosis (P=0.04) and dysgranulopoiesis (P=0.02) as independent predictors of shortened survival; the presence of zero (low risk), one (intermediate risk) or >or=2 (high risk) risk factors corresponded to median survivals of 102, 52 and 27 months, respectively. Janus kinase 2 (JAK2), thrombopoietin receptor (MPL), isocitrate dehydrogenase 1 (IDH1) and IDH2 mutational analysis was performed on archived bone marrows in 78 patients; JAK2V617F and MPLW515L mutations were shown in five (6.4%) and three (3.8%) patients, respectively, and did not seem to affect phenotype or prognosis. IDH mutations were not detected. Survival was not affected by serum ferritin and there were no instances of death directly related to iron overload. The current study is unique in its strict adherence to WHO criteria for selecting study patients and providing information on long-term survival, practical prognostic factors, baseline risk of leukemic transformation and the prevalence of JAK2, MPL and IDH mutations.

The reported incidence of molar pregnancy varies widely among different geographic locations. This variation has been attributed, at least in part, to racial/ethnic differences. While the incidence of molar pregnancies is decreasing, certain ethnic groups such as Hispanics, Asians, and American Indians continue to have an increased risk of developing gestational trophoblastic disease across the globe. We sought to describe the potential effect of ethnicity/race on the presentation and clinical course of complete mole and partial mole. All patients followed up for complete mole and partial mole at a single institution referral center from 1994 through 2013 were identified. Variables including age, race, gravidity, parity, gestational age, presenting signs/symptoms, serum human chorionic gonadotropin values, and development of gestational trophoblastic neoplasia were extracted from medical records and patient surveys. Patients with complete mole and partial mole were categorized into race/ethnicity groups defined as white, black, Asian, or Hispanic. Due to low numbers of non-white patients with partial mole in each non-white category, patients with partial mole were grouped as white or non-white. Continuous variables were compared using the Kruskal-Wallis test and binary variables were compared using the Fisher exact test. A total of 167 complete mole patients with known race/ethnicity status were included (57.48% white, 14.97% Asian, 14.37% black, 13.17% Hispanic). Hispanics presented at younger age (median 24.5 years) compared to whites (median 32.0 years, P = .04) and Asians (median 31.0 years, P = .03). Blacks had higher gravidity than whites (P < .001) and Hispanics (P = .05). There was no significant difference in presenting symptoms, gestational age at diagnosis, and preevacuation serum human chorionic gonadotropin level by race/ethnicity. Hispanics were significantly less likely than whites to develop gestational trophoblastic neoplasia (absolute risk difference, 28.6%; 95% confidence interval, 8.1-39.2%; P = .02). A total of 144 patients with partial mole were analyzed. There were 108 white and 36 non-white patients. Median age was 31 years for white and 29 years for non-white patients (P = .006). Median gravidity was 2 for white and 3 for non-white patients (P < .001), and median parity was 0 for white patients and 1 for non-white patients (P = .003). There were no significant differences with respect to presenting signs and symptoms, gestational age, preevacuation human chorionic gonadotropin level, or risk of progression to gestational trophoblastic neoplasia. Hispanic patients with complete molar pregnancy had a significantly lower risk of developing gestational trophoblastic neoplasia than white patients. There were no significant differences among groups in terms of presenting symptoms, gestational age at diagnosis, or preevacuation human chorionic gonadotropin levels for either complete mole or partial mole patients.

Introduction Acute myeloid leukemia (AML) is a heterogeneous clonal disorder of haemopoietic progenitor cells diagnosed in individuals of any age, but with a median age of 67 years at presentation in adults. Assessment of the mutation status of Nucleophosmin protein-1 (NPM1) and FMS-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) are essential for the diagnosis, prognosis and treatment of AML. Methods A total of 160 de novo AML cases, both cytogenetically normal and abnormal, were analyzed for the presence of NPM1 and FLT3-ITD mutations and the results assessed in conjunction with epidemiological, clinical and laboratory findings. Results NPM1 mutations were found in 7.5%, while FLT3-ITD was present in 12% of these cases. Both of these were lower than expected. The median age at diagnosis of AML was 41 years and for the FLT3-ITD only cases, median age was 33 years; these ages were younger than expected. Conclusion The lower reported frequencies and younger median age at diagnosis of AML and these specific mutations may be contributed to by a number of factors including; effects of race on age of presentation, inclusion of patients diagnosed with de novo AML only and a generally younger median age of the South African population.

Data from in vitro experiments suggest that vitamin D reduces the rate of skin aging, whereas population studies suggest the opposite, most likely due to confounding by UV exposure. We investigated whether there are causal associations between 25-hydroxyvitamin D concentrations and features of skin aging in a bidirectional Mendelian randomization study. In the Rotterdam Study (N = 3,831; 58.2% women, median age 66.5 years) and Leiden Longevity Study (N = 661; 50.5% women, median age 63.1 years), facial skin aging features (perceived age, wrinkling, pigmented spots) were assessed either manually or digitally. Associations between 25-hydroxyvitamin D and skin aging features were tested by multivariable linear regression. Mendelian randomization analyses were performed using single nucleotide polymorphisms identified from previous genome-wide association studies. After meta-analysis of the two cohorts, we observed that higher serum 25-hydroxyvitamin D was associated with a higher perceived age (P-value = 3.6 × 10 -7 ), more skin wrinkling (P-value = 2.6 × 10 -16 ), but not with more pigmented spots (P-value = 0.30). In contrast, a genetically determined 25-hydroxyvitamin D concentration was not associated with any skin aging feature (P-values > 0.05). Furthermore, a genetically determined higher degree of pigmented spots was not associated with higher 25-hydroxyvitamin D (P-values > 0.05). Our study did not indicate that associations between 25-hydroxyvitamin D and features of skin aging are causal. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

Purpose Lung cancer is the most common cause of cancer mortality in the world. There are limited studies on survival outcomes of lung cancer in developing countries such as India. This study analyzed the outcomes of patients with lung cancer who underwent treatment at Cancer Institute (WIA), Chennai, India, between 2006 and 2015 to determine survival outcomes and identify prognostic factors. Patients and Methods In all, 678 patients with lung cancer underwent treatment. Median age was 58 years, and 91% of patients had non–small-cell lung cancer (NSCLC). Testing for epidermal growth factor receptor mutation was performed in 132 of 347 patients and 61 (46%) were positive. Results Median progression-free survival was 6.9 months and overall survival (OS) was 7.6 months for patients with NSCLC. Median progression-free survival was 6 months and OS was 7.2 months for patients with small-cell lung cancer. On multivariable analysis, the factors found to be significantly associated with inferior OS in NSCLC included nonadenocarcinoma histology, performance status more than 2, and stage. In small-cell lung cancer, younger age and earlier stage at presentation showed significantly better survival. Conclusion Our study highlights the challenges faced in treating lung cancer in India. Although median survival in advanced-stage lung cancer is still poor, strategies such as personalized medicine and use of second-line and maintenance chemotherapy may significantly improve the survival in patients with advanced-stage lung cancer in developing countries.

Understanding service provision for patients with advanced disease is a research priority, with a need to identify barriers that limit widespread integration of palliative care. To identify patient and organisational factors that influence the duration of hospice-based palliative care in the United Kingdom prior to death. This is a retrospective cohort study. A total of 64 UK hospices providing specialist palliative care inpatient beds and community services extracted data for all adult decedents (aged over 17 years) with progressive, advanced disease, with a prior referral (e.g. inpatient, community teams, and outpatient) who died between 1 January 2015 and 31 December 2015. Data were requested for factors relating to both the patient and hospice site. Across 42,758 decedents, the median time from referral to death was 48 days. Significant differences in referral to death days were found for those with cancer (53 days) and non-cancer (27 days) ( p < 0.0001). As age increases, the median days from referral to death decreases: for those under 50 years (78 days), 50-74 years (59 days), and 75 years and over (39 days) ( p = 0.0001). An adjusted multivariable negative binomial model demonstrated increasing age persisting as a significant predictor of fewer days of hospice care, as did being male, having a missing ethnicity classification and having a non-cancer diagnosis ( p < 0.001). Despite increasing rhetoric around early referral, patients with advanced disease are receiving referrals to hospice specialist palliative care very late in their illness trajectory. Age and diagnosis persist as determinants of duration of hospice specialist palliative care before death.

To test the hypothesis that there are important differences between studies on memory published in anesthesia literature and those published in the psychopharmacology literature, we compared the two from the period January 1978 through May 1988 to identify deficiencies in the design and methodologies used and to provide guidelines for future experiments. Eight-eight articles in each discipline were reviewed. The sample sizes were larger in the articles in anesthesia journals than in those in psychopharmacology journals (medians 52.5 vs. 18 subjects, respectively). Most (85%) of the studies in the anesthesia literature used patients, who had a median age of 38.9 yr and included a median of 28 women among the subjects per study. In contrast, the majority (60%) of the studies in the psychopharmacology literature used healthy volunteers, who had a median age of 23.6 yr and included a median of only 3.5 females among the subjects per study. Characteristics more common in the psychopharmacology than in the anesthesia literature, respectively, were use of a control or placebo group (90% vs. 42%), double-blind design (80% vs. 47%), use of pre- and posttreatment memory measurements (64% vs. 23%), use of multiple memory tests with distinct equated stimuli (83% vs. 8%), relation of methodology to some theoretical model of memory (72% vs. 17%), and use of other behavioral tests (68% vs. 48%). Relative to the psychopharmacology literature, the anesthesia literature used pictures as stimuli for the memory tests more often (44% vs. 14%, respectively) and words less often (11% vs. 67%) and relied heavily on questions about recall of perioperative events (41% vs. 0%). There is room for improvement in both types of literature, and more so in the anesthesia literature.

Purpose To describe our experience with 2-stage proximal hypospadias repair and report outcomes. To look at patient and procedure characteristics associated with surgical complications. Materials and Methods This was a retrospective study of patients with proximal hypospadias who underwent staged repair from January 1993–December 2012. Demographics, preoperative management, and operative technique were reviewed. Complications included glans dehiscence, fistula, meatal stenosis, non-meatal stricture, urethrocele/diverticula, and residual chordee. Cox proportional hazards model was used to evaluate the associations between the time to surgery for complications and patient- and procedure level factors. Results There were 134 patients. The median age at time of first stage surgery was 8.8 months. The median age at time of second stage surgery was 17.1 months and median time between surgeries was 8 months. The median follow-up was 3.8 years. Complications were seen in 71/134 (53%), the most common being fistula in 39/134 (29.1%). Reoperation was performed in 66/134 (49%) patients. Median time from urethroplasty to surgery for complication was 14.9 months. Use of preoperative testosterone decreased risk of having surgery for complication by 27% (hazard ratio (HR)=0.73 95%CI:0.55–0.98, p=0.04). In addition, patients that identified as Hispanic had an increased risk of having surgery for complications (HR=2.40 95%CI:1.28–4.53, p=0.01). Conclusions This study reviews the largest cohort of patients undergoing 2-stage hypospadias repair at a single institution. Complications and reoperation are close to 50% in the setting of complex genital reconstruction. PMID:25963188

Predominantly antibody deficiencies (PADs) are the most common type of primary immunodeficiency in adults. PADs frequently pass undetected leading to delayed diagnosis, delayed treatment, and the potential for end-organ damage including bronchiectasis. In addition, PADs are frequently accompanied by comorbid autoimmune disease, and an increased risk of malignancy. To characterize the diagnostic and clinical features of adult PAD patients in Victoria, Australia. We identified adult patients receiving, or having previously received immunoglobulin replacement therapy for a PAD at four hospitals in metropolitan Melbourne, and retrospectively characterized their clinical and diagnostic features. 179 patients from The Royal Melbourne, Alfred and Austin Hospitals, and Monash Medical Centre were included in the study with a median age of 49.7 years (range: 16-87 years), of whom 98 (54.7%) were female. The majority of patients (116; 64.8%) met diagnostic criteria for common variable immunodeficiency (CVID), and 21 (11.7%) were diagnosed with X-linked agammaglobulinemia (XLA). Unclassified hypogammaglobulinemia (HGG) was described in 22 patients (12.3%), IgG subclass deficiency (IGSCD) in 12 (6.7%), and specific antibody deficiency (SpAD) in 4 individuals (2.2%). The remaining four patients had a diagnosis of Good syndrome (thymoma with immunodeficiency). There was no significant difference between the age at diagnosis of the disorders, with the exception of XLA, with a median age at diagnosis of less than 1 year. The median age of reported symptom onset was 20 years for those with a diagnosis of CVID, with a median age at diagnosis of 35 years. CVID patients experienced significantly more non-infectious complications, such as autoimmune cytopenias and lymphoproliferative disease, than the other antibody deficiency disorders. The presence of non-infectious complications was associated with significantly reduced survival in the cohort. Our data are largely consistent with the experience of other centers internationally, with clear areas for improvement, including reducing diagnostic delay for patients with PADs. It is likely that these challenges will be in part overcome by continued advances in implementation of genomic sequencing for diagnosis of PADs, and with that opportunities for targeted treatment of non-infectious complications.

Objectives To determine the efficacy and tolerability of β blockers in a broad age range of women and men with heart failure with reduced ejection fraction (HFrEF) by pooling individual patient data from placebo controlled randomised trials. Design Prospectively designed meta-analysis of individual patient data from patients aged 40-85 in sinus rhythm at baseline, with left ventricular ejection fraction <0.45. Participants 13 833 patients from 11 trials; median age 64; 24% women. Main outcome measures The primary outcome was all cause mortality; the major secondary outcome was admission to hospital for heart failure. Analysis was by intention to treat with an adjusted one stage Cox proportional hazards model. Results Compared with placebo, β blockers were effective in reducing mortality across all ages: hazard ratios were 0.66 (95% confidence interval 0.53 to 0.83) for the first quarter of age distribution (median age 50); 0.71 (0.58 to 0.87) for the second quarter (median age 60); 0.65 (0.53 to 0.78) for the third quarter (median age 68); and 0.77 (0.64 to 0.92) for the fourth quarter (median age 75). There was no significant interaction when age was modelled continuously (P=0.1), and the absolute reduction in mortality was 4.3% over a median follow-up of 1.3 years (number needed to treat 23). Admission to hospital for heart failure was significantly reduced by β blockers, although this effect was attenuated at older ages (interaction P=0.05). There was no evidence of an interaction between treatment effect and sex in any age group. Drug discontinuation was similar regardless of treatment allocation, age, or sex (14.4% in those give β blockers, 15.6% in those receiving placebo). Conclusion Irrespective of age or sex, patients with HFrEF in sinus rhythm should receive β blockers to reduce the risk of death and admission to hospital.

2012-01-01

Nerve conduction velocity slows and amplitude declines with aging. Median and ulnar sensory nerves were tested at the annual meetings of the American Dental Association. Seven hundred four subjects had at least two observations. The rate of change in the nerve parameters was estimated while controlling for gender, age, change in hand temperature, baseline body mass index (BMI), and change in BMI. Amplitudes of the median sensory nerve action potentials decreased by 0.58 μV per year, whereas conduction velocity decreased at a rate of 0.41 m/s per year. Corresponding values for the ulnar nerve were 0.89 μV and 0.29 m/s per year. The rates of change in amplitudes did not differ, but the median nerve demonstrated a more rapid loss of conduction velocity. The rate of change for the median conduction velocity was higher than previously reported. The rate of change of median conduction velocity was significantly greater than for the ulnar nerve.

Marom, E M; Helms, C A

1999-05-01

To assess the MR imaging characteristics, presenting symptoms, age and nerve distribution of fibrolipomatous hamartoma. A computer search was performed of the term fibrolipomatous hamartoma through the musculoskeletal section MR imaging results at our institution from June 7, 1996 to January 21, 1998 followed by a search of the terms lipomatous hamartoma, median nerve, surrounding fat, increased fatty signal, coaxial, and neuroma. MR images and medical files were retrospectively reviewed by two experienced musculoskeletal radiologists for imaging characteristics, nerve and age distribution as well as for history of trauma. In addition three consultation cases from outside institutions were added for determination of image characteristics. Ten fibrolipomatous hamartomas were identified: eight in the median nerve, one in the ulnar nerve and one in the sciatic nerve. Mean age was 32.3 years (range 4-75 years, SD 21 years). Imaging characteristics were serpiginous low-intensity structures representing thickened nerve fascicles, surrounded by evenly distributed fat, high signal intensity on T1-weighted sequences and low signal intensity on T2-weighted sequences. The amount of fat varied; however, distribution in eight cases (80%) was predominantly between nerve fibers rather than surrounding them peripherally. All had a coaxial-cable-like appearance on axial planes and a spaghetti-like appearance on coronal planes that was not seen in any other type of median nerve abnormality imaged during the study period. The MR imaging characteristics of fibrolipomatous hamartoma are pathognomonic, obviating the need for biopsy for diagnosis.

ABSTRACT Objective To evaluate the epidemiological profile and overall survival of a large population of elderly individuals diagnosed with solid tumors in a tertiary hospital. Methods This retrospective study included patients aged >65 years, diagnosed with solid tumors between January 2007 and December 2011, at Hospital Israelita Albert Einstein, São Paulo, Brazil. The medical records were reviewed to obtain information about clinical variables and overall survival. Results A total of 806 patients were identified, and 58.4% were male. Mean age was 74 years (65 to 99 years). The most common types were prostate (22%), colorectal (21%), breast (19%), and lung cancer (13%), followed by bladder (8%), pancreas (6%), and other types (11%). The majority of patients were diagnosed at early stage disease. After a median follow-up of 27 months (15 to 45 months), 29% of the patients (234/806) died, predominantly in the group older than 70 years. For the entire cohort, the median 2-year survival rate was 71%. Median overall survival was not reached within the study period. In a multivariate analysis, age (HR: 1.35; 95%CI: 1.25-1.45; p<0.001) and disease stage (HR: 1.93; 95%CI: 1.75-2.14; p<0.001) were independent negative predictors of poor survival. Conclusion The most prevalent tumors were prostate, colorectal, breast, and lung cancer, with the larger proportion diagnosed at initial stages, reflecting the great number of patients alive at last follow-up.

To identify the impact of in-reach services providing specialist nursing care on outcomes for older people presenting to the emergency department from residential aged care. Retrospective cohort study compared clinical outcomes of 2278 presentations from 2009 with 2051 presentations from 2011 before and after the implementation of in-reach services. Median emergency department length of stay decreased by 24 minutes (7.0 vs 6.6 hours, P < 0.001) and admission rates decreased by 23% (68 vs 45%, P < 0.001). The proportion of people with repeat emergency department visits within six months decreased by 12% (27 vs 15%). The proportion of admitted patients who were discharged with an end of life palliative care plan increased by 13% (8 vs 21%, P = 0.007). There was a significant reduction in the median length of stay, fewer hospital admissions and fewer repeat visits for people from residential aged care following implementation of in-reach services. © 2014 ACOTA.

OBJECTIVE We sought to identify risk factors for congenital microcephaly in extremely low gestational age newborns. STUDY DESIGN Demographic, clinical, and placental characteristics of 1445 infants born before the 28th week were gathered and evaluated for their relationship with congenital microcephaly. RESULTS Almost 10% of newborns (n = 138), rather than the expected 2.2%, had microcephaly defined as a head circumference >2 SD below the median. In multivariable models, microcephaly was associated with nonwhite race, severe intrauterine growth restriction, delivery for preeclampsia, placental infarction, and being female. The risk factors for a head circumference between <1 and >2 SD below the median were similar to those of microcephaly. CONCLUSION Characteristics associated with fetal growth restriction and preeclampsia are among the strongest correlates of microcephaly among children born at extremely low gestational ages. The elevated risk of a small head among nonwhites and females might reflect the lack of appropriate head circumference standards. PMID:20541727

This study examined the lifetime prevalence and correlates of attempted suicide among transgender persons in Argentina. Data were derived from a nation-wide, cross-sectional survey conducted in 2013. We assessed individual, social, and structural correlates of reporting a history of attempting suicide using logistic regression. Among 482 participants, the median age was 30, 91% identified as transwomen, and 32% resided in the Buenos Aires metropolitan area. A lifetime suicide attempt was reported by 159 (33%), among whom the median age at first attempt was 17. In a multivariate model, internalized stigma was positively associated with a history of suicidal behavior, while participants with stable housing had reduced odds of prior suicide attempt(s). These findings suggest that reducing stigma and mitigating structural vulnerabilities (through, for example, the enactment and enforcement of laws that prohibit discrimination based on gender identity to ensure equitable access to housing) could be effective targets for intervention to reduce suicide attempts among transgender individuals in Argentina.

We identified two water tanks in Tasmania with water lead concentrations exceeding the Australian Drinking Water Guidelines (ADWG) limit; they had been constructed with stainless steel and high-lead solder from a single manufacturer. An investigation was initiated to identify all tanks constructed by this manufacturer and prevent further exposure to contaminated water. To identify water tanks we used sales accounts, blood and water lead results from laboratories, and media. We analysed blood and water lead concentration results from laboratories and conducted a nested cohort study of blood lead concentrations in children aged <18 years. We identifed 144 tanks constructed from stainless steel and high lead solder. Median water lead concentrations were significantly higher in the stainless steel tanks (121µg/L) than in the galvanised tanks (1µg/L). Blood lead concentrations ranged from 1 to 26µg/dL (median 5µg/dL); of these, 77% (n=50) were below the then-recommended health-related concentration of 10µg/dL. Concentrations in the 15 people (23%) above this limit ranged from 10-26µg/dL, with a median of 14µg/dL. The median blood lead concentration in the nested cohort of children was initially 8.5µg/dL, dropping to 4.5µg/dL after follow-up. Lead concentrations in the water tanks constructed from stainless steel and high-lead solder were up to 200 times above the recommended ADWG limits. Implications for public health: This investigation highlights the public health risk posed by use of non-compliant materials in constructing water tanks. © 2017 Department of Health and Human Services Tasmania.

PurposeTo investigate the clinical impact of performing prostate artery embolization (PAE) on patients with adenomatous-dominant benign prostatic hyperplasia (AdBPH).Materials and MethodsTwelve patients from the ongoing proSTatic aRtery EmbolizAtion for the treatMent of benign prostatic hyperplasia (STREAM) trial were identified as having AdBPH; defined as two or more adenomas within the central gland of ≥1 cm diameter on multi-parametric MRI (MP-MRI). These patients were age-matched with patients from the STREAM cohort, without AdBPH. Patients were followed up with repeat MP-MRI at 3 months and 1 year. International prostate symptom score (IPSS), international index for erectile function (IIEF), and quality of life assessment from themore » IPSS and EQ-5D-5S questionnaires were recorded pre-PAE and at 6 weeks, 3 months, and 1 year.ResultsThe mean age of patients was 68 (61–76). All patients had PAE as a day-case procedure. The technical success in the cohort was 23/24 (96%). There was a significant reduction in prostate volume following embolization with a median reduction of 34% (30–55) in the AdBPH group, compared to a mean volume reduction of 22% (9–44) in the non-AdBPH group (p = 0.04). There was a significant reduction in IPSS in the AdBPH group following PAE when compared with the control group [AdBPH median IPSS 8 (3–15) vs. non-AdBPH median IPSS 13 (8–18), p = 0.01]. IPSS QOL scores significantly improved in the AdBPH group (p = 0.007). There was no deterioration in sexual function in either group post-PAE.ConclusionsThis is the first time that AdBPH has been identified as being a predictor of clinical success following PAE.« less

Steroid-resistant nephrotic syndrome (SRNS) is the second most frequent cause of end-stage renal disease (ESRD) among patients manifesting at under 25 years of age. We performed mutation analysis using a high-throughput PCR-based microfluidic technology in 24 single-gene causes of SRNS in a cohort of 72 families, who presented with SRNS before the age of 25 years. Within an 18-month interval, we obtained DNA samples, pedigree information, and clinical information from 77 consecutive children with SRNS from 72 different families seen at Boston Children's Hospital (BCH). Mutation analysis was completed by combining high-throughput multiplex PCR with next-generation sequencing. We analyzed the sequences of 18 recessive and 6 dominant genes of SRNS in all 72 families for disease-causing variants. We identified the disease-causing mutation in 8 out of 72 (11.1%) families. Mutations were detected in the six genes: NPHS1 (2 out of 72), WT1 (2 out of 72), NPHS2, MYO1E, TRPC6, and INF2. Median age at onset was 4.1 years in patients without a mutation (range 0.5-18.8), and 3.2 years in those in whom the causative mutation was detected (range 0.1-14.3). Mutations in dominant genes presented with a median onset of 4.5 years (range 3.2-14.3). Mutations in recessive genes presented with a median onset of 0.5 years (range 0.1-3.2). Our molecular genetic diagnostic study identified underlying monogenic causes of steroid-resistant nephrotic syndrome in ~11% of patients with SRNS using a cost-effective technique. We delineated some of the therapeutic, diagnostic, and prognostic implications. Our study confirms that genetic testing is indicated in pediatric patients with SRNS.

Studies on the epidemiology of primary biliary cholangitis (PBC) in the Chinese population are lacking. We aimed to determine the epidemiology of PBC in Hong Kong (HK) with a population of 7.3 million. We retrieved data from the electronic database of the HK Hospital Authority, the only public healthcare provider in Hong Kong. PBC cases between 2000 and 2015 were identified by International Classification of Diseases (ICD)-9 code. We estimated the age-/sex-adjusted incidence rate and prevalence of PBC, and analyzed the adverse outcomes (hepatocellular carcinoma (HCC), liver transplantation, and death). One thousand and sixteen PBC patients aged ≥20 years were identified (female-to-male ratio 4:1; median age 60.6 years, interquartile range (IQR) 51.8-72.6 years; median follow-up 5.6 years, IQR 1.6-8.7 years). The average age/sex-adjusted annual incidence rate and prevalence were 8.4 per million person-years and 56.4 per million, respectively. Between 2000 and 2015, the age/sex-adjusted annual incidence rate increased from 6.7 to 8.1 per million person-years (Poisson P=0.002), while age/sex-adjusted prevalence increased from 31.1 to 82.3 per million (Poisson P<0.001). Fifty patients developed HCC, and 49 underwent liver transplantation. Case fatality risk decreased from 10.8 to 6.4% (Poisson P=0.003). The 5- and 10-year overall survival rates were 81.5 and 78.3%, whereas the transplant-free survival rates were 78.0% and 74.3%, respectively. Increasing age, cirrhosis and being treatment-naïve were associated with lower transplant-free survival. There is a considerable increase in the incidence and prevalence of PBC in the Chinese population over the past 16 years, with significant morbidity and mortality.

Background: Patients with acute neurologic symptoms may have other causes simulating ischemic stroke, called stroke mimics (SM), but they may also have averted strokes that do not appear as infarcts on neuroimaging, which we call neuroimaging-negative cerebral ischemia (NNCI). We determined the safety and outcome of IV thrombolysis within 3 hours of symptom onset in patients with SM and NNCI. Methods: Patients treated with IV tissue plasminogen activator (tPA) within 3 hours of symptom onset were identified from our stroke registry from June 2004 to October 2008. We collected admission NIH Stroke Scale (NIHSS) score, modified Rankin score (mRS), length of stay (LOS), symptomatic intracerebral hemorrhage (sICH), and discharge diagnosis. Results: Among 512 treated patients, 21% were found not to have an infarct on follow-up imaging. In the SM group (14%), average age was 55 years, median admission NIHSS was 7, median discharge NIHSS was 0, median LOS was 3 days, and there were no instances of sICH. The most common etiologies were seizure, complicated migraine, and conversion disorder. In the NNCI group (7%), average age was 61 years, median admission NIHSS was 7, median discharge NIHSS was 0, median LOS was 3 days, and there were no instances of sICH. Nearly all SM (87%) and NNCI (91%) patients were functionally independent on discharge (mRS 0–1). Conclusions: Our data support the safety of administering IV tissue plasminogen activator to patients with suspected acute cerebral ischemia within 3 hours of symptom onset, even when the diagnosis ultimately is found not to be stroke or imaging does not show an infarct. GLOSSARY AIS = acute ischemic stroke; CI = confidence interval; DWI = diffusion-weighted imaging; ED = emergency department; LOS = length of stay; mRS = modified Rankin score; NIHSS = NIH Stroke Scale; NNCI = neuroimaging-negative cerebral ischemia; OR = odds ratio; sICH = symptomatic intracerebral hemorrhage; SM = stroke mimics; tPA = tissue plasminogen activator.

Extended breastfeeding duration is common in India. Extended breastfeeding protects the infant from infectious disease and promotes child spacing. In the 1990s, the median breastfeeding duration in India was 24 months. Research aim: This study aimed to investigate the median duration of breastfeeding in India and to identify the factors associated with extended breastfeeding to 24 months as recommended by the World Health Organization. This cross-sectional data analysis used nationally representative data from the 2011-2012 Indian Human Development Survey II. The outcome in this study was extended breastfeeding defined as breastfeeding to 24 months or more. Multivariate logistic regression was used to identify the factors associated with extended breastfeeding. The median duration of breastfeeding was 12 months; approximately 25% of women breastfed 24 months or more. Women were at greater odds of breastfeeding 24 months or more if the infant was a boy compared with a girl, if the women lived in a rural area compared with an urban area, if the women were married at a young age (< 17 vs. 20 years or older at marriage), and if the delivery was assisted by a friend or relative compared with a doctor. The median duration of breastfeeding has decreased by 50% from 1992-1993 to 2011-2012. The women who continue to breastfeed 24 months or more tend to be more traditional (i.e., living in rural areas, marrying young, and having family/friends as birth attendants). Further research to study the health effect of decreased breastfeeding duration is warranted.

Following a severe case of rhabdomyolysis in our University Hospital after a co-administration of atorvastatin and fusidic acid, we describe this interaction as this combination is not clearly contraindicated in some countries, particularly for long-term treatment by fusidic acid. All cases of rhabdomyolysis during a co-administration of a statin and fusidic acid were identified in the literature and in the World and Health Organization database, VigiBase ® . In the literature, 29 cases of rhabdomyolysis were identified; mean age was 66 years, median duration of co-administration before rhabdomyolysis occurrence was 21 days, 28% of cases were fatal. In the VigiBase ® , 182 cases were retrieved; mean age was 68 years, median duration of co-administration before rhabdomyolysis was 31 days and 24% of cases were fatal. Owing to the high fatality associated with this co-administration and the long duration of treatment before rhabdomyolysis occurrence, fusidic acid should be used if there is no appropriate alternative, as long as statin therapy is interrupted for the duration of fusidic acid therapy, and perhaps a week longer. Rarely will interruption of this sort have adverse consequences for the patient. © 2018 The British Pharmacological Society.

To inform estimations of the potential impact of recently introduced pneumococcal conjugate vaccine (PCV), we report results of 11 years of pre-PCV surveillance for invasive pneumococcal disease (IPD) among children in Guatemala City. Cases of IPD in children younger than 5 years were identified by active surveillance at 3 referral hospitals in Guatemala City from October 1996 through 2007. Clinical and demographic data were obtained, and isolates of Streptococcus pneumoniae from normally sterile sites were serotyped using latex agglutination and confirmed by Quellung reaction. Four hundred fifty-two cases of IPD were identified with a case fatality rate of 21%. Meningitis was the most common cause of death (77% of all deaths) and occurred more often in infancy (median age 5 months) than other clinical syndromes. Of the 137 isolates serotyped, type 1 (26 cases, 17%), type 2 (25 cases, 16%) and type 5 (18 cases, 12%) were the most common. Serotype 2 was associated with a higher case fatality rate (28%), higher rate of meningitis (68%) and occurred in younger infants (median age, 3.5 months) than other common serotypes. Recently introduced PCV13 includes 73% of observed serotypes in the study. Infants with IPD presented at a young age. Serotype 2, rarely reported as a significant cause of IPD and not included in available PCVs, was a common cause of disease in this population. PCV13 introduction in Guatemala, begun in 2013, may not have as great an impact in disease reduction as has been observed in other countries.

Turner syndrome (TS), resulting from complete/partial X chromosomal monosomy, is associated with multiple co-morbidities and increased mortality. Although multidisciplinary management is recommended, TS women's health care is sub-optimal. This study evaluates a multidisciplinary adult TS service. Retrospective cohort study of 82 patients attending the quarterly TS clinic from December 2003 to December 2014. Evaluation included (1) demographics, (2) TS standardized co-morbidity screening, and (3) estrogen therapy use. Data analysis involved frequency statistics, T tests and polychoric correlation analysis. Median age at TS diagnosis was 14 years (range 0-65 years), with 12% of women aged >18 years. Median age at initial consultation was 31 years (range 16-65 years). Only 14% of patients were transition program referrals. XO karyotype occurred in 30%. Primary amenorrhea predominated; however, 37% of TS women were not taking estrogen therapy. The proportion of patients not previously screened (44-76%) and those with positive screening diagnoses (5-53%) varied according to co-morbidity. The mean (± standard deviation) number of co-morbidities identified increased following TS clinic screening (7.0 ± 2.6 post-screening vs. 4.4 ± 2.3 pre-screening; p < 0.0001). Polychoric correlation analysis identified particular co-morbidity groupings (including metabolism-related) and increased co-morbidities with primary amenorrhea. A multidisciplinary adult TS clinic improves health surveillance with increased identification of co-morbidities and initiation of estrogen therapy.

To determine the population pharmacokinetics of unbound hydrocortisone in critically ill neonates and infants receiving IV hydrocortisone for treatment of vasopressor-resistant hypotension and to identify patient-specific sources of pharmacokinetic variability. Prospective observational cohort study. Level 3 neonatal ICU. Sixty-two critically ill neonates and infants receiving IV hydrocortisone as part of standard of care for the treatment of vasopressor-resistant hypotension: median gestational age 28 weeks (range, 23-41), median weight 1.2 kg (range, 0.5-4.4), and 29 females. None. Unbound baseline cortisol and postdose hydrocortisone concentrations measured from blood samples being drawn for routine laboratory tests. A one-compartment model best described the data. Allometric weight and postmenstrual age were significant covariates on unbound hydrocortisone clearance and volume of distribution. Final population estimates for clearance, volume of distribution, and baseline cortisol concentration were 20.2 L/hr, 244 L, and 1.37 ng/mL, respectively. Using the median weight and postmenstrual age of our subjects (i.e., 1.2 kg and 28 wk) in the final model, the typical unbound hydrocortisone clearance and volume of distribution were 1.0 L/hr and 4.2 L, respectively. The typical half-life for unbound hydrocortisone was 2.9 hours. A sharp and continuous increase in unbound hydrocortisone clearance was observed at 35 weeks postmenstrual age. We report the first pharmacokinetic data for unbound hydrocortisone, the pharmacologically active moiety, in critically ill neonates and infants with vasopressor-resistant hypotension. Unbound hydrocortisone clearance increased with body weight and was faster in children with an older postmenstrual age. Unbound hydrocortisone clearance increased sharply at 35 weeks postmenstrual age and continued to mature thereafter. This study lays the groundwork for evaluating unbound hydrocortisone exposure-response relationships and drawing definitive conclusions about the dosing of IV hydrocortisone in critically ill neonates and infants with vasopressor-resistant hypotension.

The role of exercise testing to risk stratify patients with repaired coarctation of the aorta (CoA) is controversial. Concentric left ventricular (LV) hypertrophy, defined as an increase in the LV mass-to-volume ratio (MVR), is associated with a greater incidence of adverse cardiovascular events. The objective of the present study was to determine whether a hypertensive response to exercise (HRE) is associated with increased LVMVR in patients with repaired CoA. Adults with repaired CoA who had a symptom-limited exercise test and cardiac magnetic resonance imaging examination within 2 years were identified. A hypertensive response to exercise was defined as a peak systolic blood pressure >220 mm Hg during a symptom-limited exercise test. The LV mass and volume were measured using cardiac magnetic resonance by an investigator who was unaware of patient status. We included 47 patients (median age 27.3 years, interquartile range 19.8 to 37.3), who had undergone CoA repair at a median age of 4.6 years (interquartile range 0.4 to 15.7). Those with (n = 11) and without (n = 36) HRE did not differ in age, age at repair, body surface area, arm-to-leg systolic blood pressure gradient, gender, or peak oxygen uptake with exercise. Those with a HRE had a greater mean systolic blood pressure at rest (146 ± 18 vs 137 ± 18 mm Hg, p = 0.04) and greater median LVMVR (0.85, interquartile range 0.7 to 1, vs 0.66, interquartile range 0.6 to 0.7; p = 0.04) than those without HRE. Adjusting for systolic blood pressure at rest, age, age at repair, and gender, the relation between HRE and LVMVR remained significant (p = 0.001). In conclusion, HRE was associated with increased LVMVR, even after adjusting for multiple covariates. Copyright © 2013 Elsevier Inc. All rights reserved.

The management of hyperglycemia is challenging in older patients with type 2 diabetes owing to excess fragility and risk for adverse outcomes should hypoglycemia episodes occur. We evaluated baseline β-cell function as a potential risk factor for the development of hypoglycemia when saxagliptin or glimepiride was added in patients aged ≥65 years whose type 2 diabetes was poorly controlled on stable metformin monotherapy. A post hoc analysis of data from the GENERATION (Efficacy and Tolerability of Saxagliptin Compared with Glimepiride in Elderly Patients with Type 2 Diabetes: A Randomized, Controlled Study) trial, which enrolled 720 patients aged ≥65 years, was conducted. β-Cell function was assessed using homeostasis model assessment-2%β (HOMA-2%β). The percentage of patients experiencing any hypoglycemia event (ie, symptomatic event or event of plasma glucose concentration <54 mg/dL regardless of symptoms) was lower with saxagliptin compared with glimepiride (5.8% vs 34.8%). Regardless of treatment, patients with lower (median HOMA-2%β ≤39.1% [≤median]) versus higher (HOMA-2%β above median value [>median]) baseline β-cell function had a higher hypoglycemia event rate (1.27 vs 0.82 events/patient-year; adjusted incidence rate ratio [IRR] = 1.800; 95% CI, 1.501-2.159). In patients receiving glimepiride, the hypoglycemia event rate was higher in patients with baseline HOMA-2%β ≤median versus >median (2.29 vs 1.60 events/patient-year; adjusted IRR = 1.737; 95% CI, 1.439-2.097); corresponding saxagliptin hypoglycemia event rates were too low to draw meaningful conclusions (0.16 vs 0.09 events/patient-year; adjusted IRR = 2.457; 95% CI, 1.148-5.256). The association between lower β-cell function at baseline and increased prevalence of hypoglycemia was particularly strong in patients aged ≥75 years (adjusted IRR = 2.409; 95% CI, 1.686-3.442; P < 0.001), although it was also significant in patients aged 65 to <75 years old (adjusted IRR, 1.654; 95% CI, 1.339-2.043; P < 0.001). In patients with lower β-cell function, the addition of a sulfonylurea to a metformin regimen was associated with an increased risk for hypoglycemia compared with that in patients with higher β-cell function; low hypoglycemia event rates with the addition of saxagliptin limited equivalent assessments. These findings in older patients are especially relevant because morbidity associated with hypoglycemia is higher in this age group. ClinicalTrials.gov identifier: NCT01006603 (ClinicalTrials.gov).

Primary human immunodeficiency virus type 1 (HIV-1) infection is often under-diagnosed because of its nonspecific presentations. Elevated aminotransferase levels is one of its clinical manifestations, but is infrequently reported in the literature. The objective of this study was to investigate cases of elevated aminotransferases as a manifestation of primary HIV-1 infection. A retrospective chart review from October 1990 to May 2009 of HIV-1 infected patients in a registered database at a tertiary hospital was conducted to identify patients diagnosed with primary HIV-1 infection. An elevated aminotransferase level was broadly defined as above-normal values of alanine or aspartate aminotransferases. Acute hepatitis markers were determined using stored serum samples. Twenty-three of the 827 (2.8%) patients were identified as having a primary HIV-1 infection. All were male, with a median age of 26 years (range, 19-77 years), and the majority were men who had sex with men (19/23, 82.6%). The most common clinical manifestations were fever (95.7%), elevated aminotransferases (65.2%), fatigue (47.8%), and pharyngitis (47.8%). The median CD4 lymphocyte count was 374/μL (range, 109-674/μL) and the median log HIV viral load was 5.0 (range, 4.3-5.9). For the 15 patients with abnormal liver function tests, the median aspartate aminotransferase level was 112 U/L (range, 62-969 U/L) and the median alanine aminotransferase level was 146 U/L (range, 42-1,110 U/L). Elevated aminotransferases may be an initial manifestation of primary HIV infection and is more common than expected. Primary HIV-1 infection should be one of the differential diagnoses considered in young men presenting with unexplained, new-onset liver function impairment.

Probability proportional to size sampling was employed to randomly select children from thirty townships where the median iodine content in drinking water ranged from 150 to 300 μg/l; their urinary iodine concentrations were determined and their thyroid volumes were measured by ultrasound. Drinking water samples and salt samples from the villages where the children lived were collected using a systematic sampling method. Hebei Province of China. A total of 1259 children aged 8-10 years (621 boys and 638 girls). Children's median urinary iodine concentration was found to be 418·8 μg/l, and the iodine concentration was >300 μg/l for 68·3 % (248/363) of the urine samples. Children's median urinary iodine concentration in villages with median salt iodine >10 mg/kg was significantly higher than that in villages with median salt iodine <5 mg/kg (442·9 μg/l v. 305·4 μg/l, P ≈ 0). The goitre rate of 1259 children examined by ultrasound was 10·96 %. The iodine intake of children living in areas with mildly excessive iodine in drinking water in Hebei Province was found to be excessive. The measured iodine excess in the sampled children is exacerbated by consumption of iodized salt. Goitre was identified in these areas; however, due to the limitation of the current criteria for children's thyroid volume, a comprehensive assessment of the prevalence of goitre in these regions could not be made and further study is required.

Purpose: This study evaluates outcomes and patterns of care among patients receiving radiation therapy (RT) for bone metastases at a high-volume academic institution. Methods and Materials: Records of all patients whose final RT course was for bone metastases from April 2007 to July 2012 were identified from electronic medical records. Chart review yielded demographic and clinical data. Rates of complicated versus uncomplicated bone metastases were not analyzed. Results: We identified 339 patients whose final RT course was for bone metastases. Of these, 52.2% were male; median age was 65 years old. The most common primary was non-small-cell lung cancer (29%). Most patientsmore » (83%) were prescribed ≤10 fractions; 8% received single-fraction RT. Most patients (52%) had a documented goals of care (GOC) discussion with their radiation oncologist; hospice referral rates were higher when patients had such discussions (66% with vs 50% without GOC discussion, P=.004). Median life expectancy after RT was 96 days. Median survival after RT was shorter based on inpatient as opposed to outpatient status at the time of consultation (35 vs 136 days, respectively, P<.001). Hospice referrals occurred for 56% of patients, with a median interval between completion of RT and hospice referral of 29 days and a median hospice stay of 22 days. Conclusions: These data document excellent adherence to American Society for Radiation Oncolology Choosing Wisely recommendation to avoid routinely using >10 fractions of palliative RT for bone metastasis. Nonetheless, single-fraction RT remains relatively uncommon. Participating in GOC discussions with a radiation oncologist is associated with higher rates of hospice referral. Inpatient status at consultation is associated with short survival.« less

To complement a case series review of button battery impactions managed at our single military tertiary care center with a thorough literature review of laboratory research and clinical cases to develop a protocol to optimize patient care. Specifically, to identify predictive factors of long-term complications which can be used by the pediatric otolaryngologist to guide patient management after button battery impactions. A retrospective review of the Department of Defense's electronic medical record systems was conducted to identify patients with button battery ingestions and then characterize their treatment course. A thorough literature review complemented the lessons learned to identify potentially predictive clinical measures for long-term complications. Eight patients were identified as being treated for button battery impaction in the aerodigestive tract with two sustaining long-term complications. The median age of the patients treated was 33 months old and the median estimated time of impaction in the aerodigestive tract prior to removal was 10.5 h. Time of impaction, anatomic direction of the battery's negative pole, and identifying specific battery parameters were identified as factors that may be employed to predict sequelae. Based on case reviews, advancements in battery manufacturing, and laboratory research, there are distinct clinical factors that should be assessed at the time of initial therapy to guide follow-up management to minimize potential catastrophic sequelae of button battery ingestion.

Pseudo-Bartter Syndrome (PBS), although quite common in patients with cystic fibrosis (CF), is often missed as simple dehydration or Bartter syndrome. This study was performed in patients with PBS to compare the pattern and course of the disease with those with CF not manifesting with this syndrome. All patients with CF who attended the respiratory clinic at Queen Rania Al-Abdallah Hospital from January 2000 to April 2010 were included in this retrospective case-control study. A specially formulated data sheet was used and those with PBS and those not having the syndrome were identified. A total of 110 patients (51% female) with CF with a median age of seven years were followed-up. Eighteen (16.3%) of them had one or more episodes of PBS. The median follow-up period was 6.2 years. All the episodes occurred during summer and in infancy. Median age of the initial episode of PBS was three months. One-third of them were initially followed at the nephrology clinic. Three patterns of PBS were identified: single episode in three (16.6%) patients, recurrent in 12 (66.6%) patients and chronic in three (16.6%) patients. Early colonization of Pseudomonas spp before 1 st birthday was seen in 44% patients with PBS compared with 12% in other CF patients (P-value = 0.0075). The total number of colonized patients and other CF features at the time of the study did not differ significantly among patients, although the mean Shwachman-Kulczycki score is significantly lower in those with recurrent PBS (69 compared with 85 in other CF patients). Gene mutation was identified in only 30% of the entire cohort. PBS is common in patients with CF, and it should be kept in mind in any patient with hypotonic dehydration and metabolic alkalosis. Recurrent pattern is associated with earlier Pseudomonas colonization.

Purpose: To identify the incidence and the risk factors for pulmonary toxicity in children treated for cancer with contemporary lung irradiation. Methods and Materials: We analyzed clinical features, radiographic findings, pulmonary function tests, and dosimetric parameters of children receiving irradiation to the lung fields over a 10-year period. Results: We identified 109 patients (75 male patients). The median age at irradiation was 13.8 years (range, 0.04-20.9 years). The median follow-up period was 3.4 years. The median prescribed radiation dose was 21 Gy (range, 0.4-64.8 Gy). Pulmonary toxic chemotherapy included bleomycin in 58.7% of patients and cyclophosphamide in 83.5%. The followingmore » pulmonary outcomes were identified and the 5-year cumulative incidence after irradiation was determined: pneumonitis, 6%; chronic cough, 10%; pneumonia, 35%; dyspnea, 11%; supplemental oxygen requirement, 2%; radiographic interstitial lung disease, 40%; and chest wall deformity, 12%. One patient died of progressive respiratory failure. Post-irradiation pulmonary function tests available from 44 patients showed evidence of obstructive lung disease (25%), restrictive disease (11%), hyperinflation (32%), and abnormal diffusion capacity (12%). Thoracic surgery, bleomycin, age, mean lung irradiation dose (MLD), maximum lung dose, prescribed dose, and dosimetric parameters between V{sub 22} (volume of lung exposed to a radiation dose ≥22 Gy) and V{sub 30} (volume of lung exposed to a radiation dose ≥30 Gy) were significant for the development of adverse pulmonary outcomes on univariate analysis. MLD, maximum lung dose, and V{sub dose} (percentage of volume of lung receiving the threshold dose or greater) were highly correlated. On multivariate analysis, MLD was the sole significant predictor of adverse pulmonary outcome (P=.01). Conclusions: Significant pulmonary dysfunction occurs in children receiving lung irradiation by contemporary techniques. MLD rather than prescribed dose should be used to perform risk stratification of patients receiving lung irradiation.« less

Recently, automated alerts have been used to identify patients with respiratory failure based on set criteria, which can be gleaned from the electronic medical record (EMR). Such an approach may also be useful for identifying patients with severe adult respiratory distress syndrome (ARDS) who may benefit from extracorporeal membrane oxygenation (ECMO). Inhaled nitric oxide (iNO) is a common rescue therapy for severe ARDS which can be easily tracked in the EMR, and some patients started on iNO may have indications for initiating ECMO. This case series summarizes our experience with using automated electronic alerts for ECMO team activation focused particularly on an alert triggered by the initiation of iNO. After a brief trial evaluation, our Smart Alert system generated an automated page and e-mail alert to ECMO team members whenever a nonzero value for iNO appeared in the respiratory care section of our EMR. If iNO was initiated for severe respiratory failure, a detailed evaluation by the ECMO team determined if ECMO was indicated. For those patients managed with ECMO, we tabulated baseline characteristics, indication for ECMO, and outcomes. From September 2012 to July 2013, 45 iNO alerts were generated on 42 unique patients. Six patients (14%) met criteria for ECMO. Of these, four were identified exclusively by the iNO alert. At the time of the alert, the median PaO₂-to-FIO₂ ratio was 64 mm Hg (range, 55-107 mm Hg), the median age-adjusted oxygenation index was 73 (range, 51-96), and the median Murray score was 3.4 (range, 3-3.75), indicating severe respiratory failure. Median time from iNO alert to ECMO initiation was 81 hours (range, -2-292 hours). Survival to hospital discharge was 83% in those managed with ECMO. Automated alerts may be useful for identifying patients with severe ARDS who may be ECMO candidates. Diagnostic test, level V.

To investigate the clinical features of gynecological malignant tumor related multiple primary malignant neoplasms (MPMN). Apply retrospective and comprehensive analysis to the clinical data of 30 patients with gynecological malignant tumor related MPMN. Synchronous MPMN were found in 9 patients. Their average age was 50.2 years old and their median age was 49 years old. The neoplasms were located at ovary, uterus, cervix, breast and intestine. Metachronous MPMN were found in 21 patients. Their average age was 57.7 and their median age was 57 years old. The median interval between the first and the second primary malignant neoplasm was 4.0 years. The neoplasms were located at breast, ovary, uterus, gastrointestinal tract, uterine cervix, lung etc. In 30 cases, 26 of them were treated by surgical operation and further adjunctive treatment of chemotherapy and (or) radiotherapy was conducted as per the neoplasm staging and its pathological results. The rest 4 patients (first primary malignant neoplasms were excised from 3 of them and another one was not treated by surgical operation) received adjunctive treatment of chemotherapy and (or) radiotherapy. Followed ups, which varied from 6 to 60 months, were made to 29 patients and 20 out of the 29 were alive.5-year survival rate of patients with gynecological malignant tumor related MPMN was 47.8%, 2-year survival rate was 73.9%, and 1-year survival rate was 88.6%. Pay more attention to the patients with gynecological malignant tumor related MPMN, examine the high-risk patients with malignant tumor comprehensively, identify whether it is recurrence, metastasis or new growth of malignant neoplasm, and further ensure early diagnosis and proper treatment, avoiding misdiagnosis and missed diagnosis.

Primary evidence for the role of endocrinologic investigations in patients with adolescent gynecomastia is lacking in the current literature. The objective of this study was to assess the yield of endocrinologic investigations in the evaluation of adolescent gynecomastia to inform current practice for this common condition. A 26-year retrospective review was conducted. Data collection included patients with gynecomastia presenting to endocrinology at a quaternary children's hospital with a catchment area of 1 million. Clinical metrics, endocrinologic results, treatments, and costs were reviewed. One hundred ninety-seven patients met inclusion criteria. Ninety-eight (50 percent) were overweight or obese and 29 (15 percent) had a positive family history. The median age at onset was 11.5 years; 25 cases (13 percent) were prepubertal. A total of 15 patients (7.6 percent) were diagnosed with secondary gynecomastia (10 related to exogenous substance use). Endocrine investigations were performed in 173 patients (87 percent), with positive findings in three cases (1.7 percent). One hundred one patients were observed, with a median age at resolution of 14.6 years; 86 patients underwent surgery at a median age of 16.5 years. The case-cost of endocrine evaluation was $389. Endocrinologic workup identified secondary gynecomastia in 7.6 percent of patients, of which only 1.7 percent were evident on blood work. This workup is associated with an avoidable case-cost burden to the health care system and largely unnecessary testing for the child. Because a majority of secondary gynecomastia cases (67 percent) were drug-induced, we do not suggest routine endocrinology workup, as it adds little value. The authors' data suggest that referral for surgery is warranted if gynecomastia persists beyond 16 years of age. Diagnostic, IV.

Early treatment is associated with improved cognition in Hurler syndrome.

Poe, Michele D; Chagnon, Sarah L; Escolar, Maria L

Hurler syndrome is the most clinically severe form of an autosomal recessive lysosomal disorder characterized by the deficiency of α-L-iduronidase. The resulting accumulation of glycosaminoglycans causes progressive multisystem deterioration, resulting in death in childhood. Umbilical cord blood transplantation from unrelated donors has been previously shown to improve neurological outcomes of children <2 years of age and prolong life. The purpose of this article is to determine whether age at transplantation can predict cognitive outcomes. Between June 1997 and February 2013, 31 patients with Hurler syndrome underwent umbilical cord blood transplantation and were evaluated at baseline and every 6 to 12 months thereafter. All 31 patients underwent complete neurodevelopmental evaluation (median follow-up = 7.3 years, range = 2-21.7) and a median of 7.0 evaluations (range = 3-18). Younger age at transplantation was associated with improved cognitive function (p = 0.001), receptive and expressive language (p = 0.004 and p = 0.01), and adaptive behavior (p = 0.03). Early age at transplantation is a strong predictor of cognitive, language, and adaptive behavior outcomes. Children younger than 9 months at the time of transplant showed normal cognitive development. Our results demonstrate that early diagnosis is necessary for optimal outcomes and support the need for newborn screening, because most patients are not identified at this young age. © 2014 American Neurological Association.

A first trimester trisomy 13/trisomy 18 risk algorithm combining fetal nuchal translucency thickness, maternal serum free beta-hCG and PAPP-A.

This study examines 45 cases of trisomy 13 and 59 cases of trisomy 18 and reports an algorithm to identify pregnancies with a fetus affected by trisomy 13 or 18 by a combination of maternal age fetal nuchal translucency (NT) thickness, and maternal serum free beta-hCG and PAPP-A at 11-14 weeks of gestation. In this mixed trisomy group the median MoM NT was increased at 2.819, whilst the median MoMs for free beta-hCG and PAPP-A were reduced at 0.375 and 0.201 respectively. We predict that with the use of the combined trisomy 13 and 18 algorithm and a risk cut-off of 1 in 150 will for a 0.3% false positive rate allow 95% of these chromosomal defects to be identified at 11-14 weeks. Such algorithms will enhance existing first trimester screening algorithms for trisomy 21. Copyright 2002 John Wiley & Sons, Ltd.

To describe, in a sample of pediatric onco-hematological patients, the rate of occlusions in unused central venous catheters (CVC) flushed once a week with a 0.9% sodium chloride solution through a positive-pressure-valve needleless connector. Retrospective cohort study. Subjects aged 0-17 years were identified through a manual search in medical and nursing records and were observed for two years or until the occurrence of one of the following events: start or resume of continuous infusion; CVC removal; death. The primary study outcome was the frequency of CVC occlusion (partial or complete). Fifty-one patients were identified (median age 6 years). The median duration of follow-up was 169 days (IQR 111-305). During the follow up period, 14 patients (27%) had one CVC occlusion, in 2 cases (4%) the occlusion was complete, in 12 (23%) partial. All the occlusions were solved without the need for catheter removal. The lumen diameter ≤ 4.2 vs > 4.2 French showed a statistically significant association with occlusion at multivariate analysis (OR 4.0; 95% CI 1.1-14.7). Our findings are reassuring with respect to the management of the CVC using the adopted protocol. The study provides useful information for patient care, by verifying the performance of the adopted CVC management protocol and by identifying critical areas for nursing care.

The aim of this study was to identify predictors of a superior functional outcome after corrective osteotomy for paediatric malunited radius and both-bone forearm fractures. We performed a systematic review and meta-analysis of individual participant data, searching databases up to 1 October 2016. Our primary outcome was the gain in pronosupination seen after corrective osteotomy. Individual participant data of 11 cohort studies were included, concerning 71 participants with a median age of 11 years at trauma. Corrective osteotomy was performed after a median of 12 months after trauma, leading to a mean gain of 77° in pronosupination after a median follow-up of 29 months. Analysis of variance and multiple regression analysis revealed that predictors of superior functional outcome after corrective osteotomy are: an interval between trauma and corrective osteotomy of less than 1 year, an angular deformity of greater than 20° and the use of three-dimensional computer-assisted techniques.

2018-05-01

A significant proportion of patients with acute stroke symptoms have an alternative 'mimic' diagnosis. A narrative review was carried out to explore the frequency, characteristics and aetiology of stroke mimics. Prehospital and thrombolysis-treated patients were described separately. Overall, 9972 studies were identified from the initial search and 79 studies were included with a median stroke mimic rate of 19% (range: 1-64%). The prehospital median was 27% (range: 4-43%) and the thrombolysis median 10% (range: 1-25%). Seizures, migraines and psychiatric disorders are the most frequently reported causes of stroke mimics. Several characteristics are consistently associated with stroke mimics; however, they do not fully exclude the possibility of stroke. Nineteen per cent of suspected stroke patients had a mimic condition. Stroke mimics were more common with younger age and female sex. The range of mimic diagnoses, a lack of clear differentiating characteristics and the short treatment window for ischaemic stroke create challenges for early identification.

The main aim of our study was to investigate the handedness of patients with mesial temporal lobe epilepsy (MTLE). We also sought to identify clinical variables that correlated with left-handedness in this population. Handedness (laterality quotient) was assessed in 73 consecutive patients with MTLE associated with unilateral hippocampal sclerosis (HS) using the Edinburgh Handedness Inventory. Associations between right- and left-handedness and clinical variables were investigated. We found that 54 (74.0%) patients were right-handed, and 19 (26%) patients were left-handed. There were 15 (36.6%) left-handed patients with left-sided seizure onset compared to 4 (12.5%) left-handed patients with right-sided seizure onset (p=0.030). Among patients with left-sided MTLE, age at epilepsy onset was significantly correlated with handedness (8years of age [median; min-max 0.5-17] in left-handers versus 15years of age [median; min-max 3-30] in right-handers (p<0.001). Left-sided MTLE is associated with atypical handedness, especially when seizure onset occurs during an active period of brain development, suggesting a bi-hemispheric neuroplastic process for establishing motor dominance in patients with early-onset left-sided MTLE.

Rhabdomyolysis is a potentially life threatening condition of various etiology. The association between rhabdomyolysis and muscular dystrophies is under-recognized in clinical practice. To identify muscular dystrophies presenting with rhabdomyolysis at onset or as predominant feature. We retrospectively reviewed clinical and laboratory data of patients with a genetically confirmed muscular dystrophy in whom rhabdomyolysis was the presenting or main clinical manifestation. Thirteen unrelated patients (males=6; females=7) were identified. Median age at time of rhabdomyolysis was 18 years (range, 2-47) and median duration between the first episode of rhabdomyolysis and molecular diagnosis was 2 years. Fukutin-related protein (FKRP) muscular dystrophy (n=6) was the most common diagnosis, followed by anoctaminopathy-5 (n=3), calpainopathy-3 (n=2) and dystrophinopathy (n=2). Four patients experienced recurrent rhabdomyolysis. Eight patients were asymptomatic and 3 reported myalgia and exercise intolerance prior to the rhabdomyolysis. Exercise (n=6) and fever (n=4) were common triggers; rhabdomyolysis was unprovoked in 3 patients. Twelve patients required hospitalization. Baseline CK levels were elevated in all patients (median 1200 IU/L; range, 600-3600). Muscular dystrophies can present with rhabdomyolysis; FKRP mutations are particularly frequent in causing such complication. A persistently elevated CK level in patients with rhabdomyolysis warrants consideration for underlying muscular dystrophy. Copyright © 2015 Elsevier B.V. All rights reserved.

Pancreatico-enteric anastomotic (PEA) stenosis is one of the late complications following pancreaticoduodenectomy (PD) and reported for benign diseases. Literature for PEA stenosis following PD for malignancy is very limited due to low survival. Patients undergoing surgery for symptomatic, recurrent, obstructive pancreatitis due to PEA stenosis following PD for malignancy were retrospectively identified from the authors' prospective database between January 1997 and December 2014. Six patients with median age 56.5 years underwent revision surgery for PEA stenosis during this time period. At primary PD, all were node negative with T1/T2 disease. The primary PEA were pancreatico-jejunostomy (PJ) (n = 5) and pancreatico-gastrostomy (n = 1). Median time to develop symptoms was 62 months. At revision surgery, a Roux-en-Y longitudinal PJ (n = 5) and an end-to-side PJ (n = 1) were done. With a median follow-up of 36 months, pain relief was excellent (n = 5) to average (n = 1). With improving long-term survival in patients undergoing PD for malignancy more such patients will be identified in future. Patients with symptomatic PEA stenosis following PD for malignancy can be managed surgically, with excellent outcomes in centers of expertise in pancreatic surgery.

Locally advanced breast cancer in Saudi Arabia: high frequency of stage III in a young population.

In the Kingdom of Saudi Arabia (KSA), breast cancer constitutes 18% of all cancers in Saudi women. Whilst locally advanced breast cancer disease is unusual in Western countries, it constitutes more than 40% of all non-metastatic breast cancer in KSA. The relative frequency of locally advanced disease among our breast cancer population and the lack of a uniform consensus in the literature about its optimal management have prompted this retrospective analysis of the medical records of patients with Stage III breast cancer patients seen at King Faisal Specialist Hospital and Research Center between 1981 and 1991. In all, 315 patients were identified. Their median age +/- SD was 46 +/- 11.6 years which is distinctly different from the 60-65 years median age in industrial Western nations. Most patients were younger than 50 years (64%) and premenopausal (62%). Patients were approximately equally divided between Stage IIIA and Stage III B. Patients received multimodality treatment, including surgery, adjuvant chemotherapy, tamoxifen, and adjuvant radiotherapy. Sixty-one patients were excluded from survival analysis as they were considered lost to follow-up. Of the remaining 254 patients, 73 (29%) were alive and disease free, and 18 patients (7%) were alive but with evidence of the disease. The remaining 163 (64%) had died from breast cancer or its related complications. Their median overall survival (OS) was 54 months, (95% CI, 27 to 121 months) and the median progression-free survival (PFS) was 28.8 months (95% CI, 14.2 to 113 months). Cox proportional hazard model identified Stage III B and the number of positive axillary lymph nodes as poor predictors of OS and PFS. Radiotherapy was the only adjuvant modality that affected survival favourably. The prognosis of patients with Stage III disease remains poor despite the use of a multimodality approach. The overall young age of our patients may have contributed to the poor outcome. Moreover, the adverse effect of Stage III B disease (as compared with Stage III A) and axillary nodal status was evident. Whilst the favourable effect of radiotherapy on survival was demonstrated, the lack of independent efficacy of other modalities (adjuvant chemotherapy and tamoxifen) or the apparent deleterious effect of neoadjuvant chemotherapy should be addressed with discretion in such retrospective analysis. Optimal management of patients with locally advanced breast cancer disease should be appraised in well designed, prospective, randomised studies.

To investigate the utilization of health care services before and after transfer from pediatric to adult rheumatology care in clinical practice. Using US commercial claims data from January 2005 through August 2012, we identified individuals with a JIA diagnosis code from a pediatric rheumatologist followed by any diagnosis code from an adult rheumatologist. Individuals had 6 months observable time before the last pediatric visit and 6 months after the first adult visit. Medication, emergency room, physical therapy use, and diagnosis codes were compared between the pediatric and adult interval using McNemar's test. The proportion of days covered (PDC) of TNFi for the time between last pediatric and first adult visit was calculated. We identified 58 individuals with JIA who transferred from pediatric to adult rheumatology care after the age of 14. The median age at the last pediatric rheumatology visit was 18.1 years old and the median transfer interval was 195 days. 29 % of patients received NSAIDs in the adult interval compared to 43 % in the pediatric interval (p = 0.06). In the pediatric interval, 71 % received a JRA and 0 % received an RA physician diagnosis code compared to 28 and 45 %, respectively, in the adult interval. The median PDC for patients receiving a TNFi was 0.75 during the transfer interval. Individuals with JIA who transferred to adult care were more likely receive a diagnosis of RA instead of JRA and were less likely to receive NSAIDs, but had no significant immediate changes to other medication use.

To assess the emerging use of Twitter by urological journals. A search of the Journal of Citation Reports 2012 was performed to identify urological journals. These journals were then searched on Twitter.com. Each journal website was accessed for links to social media (SoMe). The number of 'tweets', followers and age of profile was determined. To evaluate the content, over a 6-month period (November 2013 to April 2014), all tweets were scrutinised on the journals Twitter profiles. To assess SoMe influence, the Klout score of each journal was also calculated. In all, 33 urological journals were identified. Eight (24.2%) had Twitter profiles. The mean (range) number of tweets and followers was 557 (19-1809) and 1845 (82-3692), respectively. The mean (range) age of the twitter profiles was 952 (314-1758) days with an average 0.88 tweets/day. A Twitter profile was associated with a higher mean impact factor of the journal (mean [sd] 3.588 [3.05] vs 1.78 [0.99], P = 0.013). Over a 6-month period, November 2013 to April 2014, the median (range) number of tweets per profile was 82 (2-415) and the median (range) number of articles linked to tweets was 73 (0-336). Of these 710 articles, 152 were Level 1 evidence-based articles, 101 Level 2, 278 Level 3 and 179 Level 4. The median (range) Klout score was 47 (19-58). The Klout scores of major journals did not exactly mirror their impact factors. SoMe is increasingly becoming an adjunct to traditional teaching methods, due to its convenient and user-friendly platform. Recently, many of the leading urological journals have used Twitter to highlight significant articles of interest to readers. © 2014 The Authors. BJU International © 2014 BJU International.

Little data are available concerning the role of general practitioners (GPs) in the diagnosis of melanoma. To evaluate the actual role of GPs in a population-based study covering five regions of France and 8·2 million inhabitants. A survey of cancer registries and pathology laboratories, and questionnaires to practitioners were used to identify incident melanomas in 2008, and evaluate characteristics of patients (age, sex, area of residence, social isolation), tumours (Breslow, ulceration, location, histological type), and GPs (training, conditions of practice), and their influence on patterns of diagnosis and Breslow thickness. Among 898 melanomas, 376 (42%) were first diagnosed in a general practice setting (GP group). Breslow thickness was much higher in the GP group than in other melanomas (median: 0·95 vs. 0·61 mm, P < 0·0001). Multivariate analysis identified an older age, lower limb location, nodular subtype and Breslow thickness as factors associated with the GP group. Within this group, 52·5% of melanomas were detected by patients (median Breslow thickness: 1·30 mm) and 47·5% by GPs (median Breslow thickness: 0·80 mm, P = 0·0009), including 8% during a systematic full-body skin examination. Previous GP training on melanoma was associated with active detection by GPs. Male sex and social isolation of patients were associated with thicker melanomas, whereas active detection by GPs was associated with thinner CMs. GPs play a key role in melanoma diagnosis in France, but still frequently detect thick tumours. Increasing awareness and training of GPs and focusing attention on male and/or socially isolated patients should help to improve early detection of melanoma. © 2012 The Authors.

Purpose To investigate the impact of modern postoperative radiotherapy (PORT) on overall survival (OS) for patients with N2 non–small-cell lung cancer (NSCLC) treated nationally with surgery and adjuvant chemotherapy. Patients and Methods Patients with pathologic N2 NSCLC who underwent complete resection and adjuvant chemotherapy from 2006 to 2010 were identified from the National Cancer Data Base and stratified by use of PORT (≥ 45 Gy). A total of 4,483 patients were identified (PORT, n = 1,850; no PORT, n = 2,633). The impact of patient and treatment variables on OS was explored using Cox regression. Results Median follow-up time was 22 months. On univariable analysis, improved OS correlated with younger age, treatment at an academic facility, female sex, urban population, higher income, lower Charlson comorbidity score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT. On multivariable analysis, improved OS remained independently predicted by younger age, female sex, urban population, lower Charlson score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT (hazard ratio, 0.886; 95% CI, 0.798 to 0.988). Use of PORT was associated with an increase in median and 5-year OS compared with no PORT (median OS, 45.2 v 40.7 months, respectively; 5-year OS, 39.3% [95% CI, 35.4% to 43.5%] v 34.8% [95% CI, 31.6% to 38.3%], respectively; P = .014). Conclusion For patients with N2 NSCLC after complete resection and adjuvant chemotherapy, modern PORT seems to confer an additional OS advantage beyond that achieved with adjuvant chemotherapy alone.

In this study, age at menopause was examined in relation to demographic and life style factors among Latin-American immigrants to Madrid and their Spanish counterparts. Respondents were drawn from the Decisions at Menopause Study (2002-2003) and from a recent sample of Latin-American immigrants to Madrid (2010-2011). The final sample included 484 women after excluding women with induced menopause and use of HT. Probit analyses and Cox proportional hazard models were used to estimate median age at menopause and to identify factors associated with an early age at menopause. Median estimated age at natural menopause was 52.0 years (51.2-53.0) for Spanish women and 50.5 years (49.9-51.2) for Latin-American women. Immigrant women were more likely to reach menopause at an earlier age after controlling for confounding factors. Nulliparity and lower levels of education were associated with an earlier age at menopause. A higher body mass index was associated with a later age at menopause in the Spanish model. Among the Latin-American sample, women from the Dominican Republic and women who underwent menopause before migrating were more likely to reach menopause at an earlier age. The results reported here demonstrate that early life events, including place of birth, and later life events, such as timing of migration, were associated with age at menopause. This study highlights the importance of taking into account differences in the age of onset of menopause in the multicultural population of Madrid when considering the health of women at midlife and beyond.

Contrary to conventional wisdom, the rectoanal gradient during evacuation is negative in many healthy people, undermining the utility of anorectal high-resolution manometry (HRM) for diagnosing defecatory disorders. We aimed to compare HRM and magnetic resonance imaging (MRI) for assessing rectal evacuation and structural abnormalities. We performed a retrospective analysis of 118 patients (all female; 51 with constipation, 48 with fecal incontinence, and 19 with rectal prolapse; age, 53 ± 1 years) assessed by HRM, the rectal balloon expulsion test (BET), and MRI at Mayo Clinic, Rochester, Minnesota, from February 2011 through March 2013. Thirty healthy asymptomatic women (age, 37 ± 2 years) served as controls. We used principal components analysis of HRM variables to identify rectoanal pressure patterns associated with rectal prolapse and phenotypes of patients with prolapse. Compared with patients with normal findings from the rectal BET, patients with an abnormal BET had lower median rectal pressure (36 vs 22 mm Hg, P = .002), a more negative median rectoanal gradient (-6 vs -29 mm Hg, P = .006) during evacuation, and a lower proportion of evacuation on the basis of MRI analysis (median of 40% vs 80%, P < .0001). A score derived from rectal pressure and anorectal descent during evacuation and a patulous anal canal was associated (P = .005) with large rectoceles (3 cm or larger). A principal component (PC) logistic model discriminated between patients with and without prolapse with 96% accuracy. Among patients with prolapse, there were 2 phenotypes, which were characterized by high (PC1) or low (PC2) anal pressures at rest and squeeze along with higher rectal and anal pressures (PC1) or a higher rectoanal gradient during evacuation (PC2). In a retrospective analysis of patients assessed by HRM, measurements of rectal evacuation by anorectal HRM, BET, and MRI were correlated. HRM alone and together with anorectal descent during evacuation may identify rectal prolapse and large rectoceles, respectively, and also identify unique phenotypes of rectal prolapse.

Purpose Advanced-stage mycosis fungoides (MF; stage IIB to IV) and Sézary syndrome (SS) are aggressive lymphomas with a median survival of 1 to 5 years. Clinical management is stage based; however, there is wide range of outcome within stages. Published prognostic studies in MF/SS have been single-center trials. Because of the rarity of MF/SS, only a large collaboration would power a study to identify independent prognostic markers. Patients and Methods Literature review identified the following 10 candidate markers: stage, age, sex, cutaneous histologic features of folliculotropism, CD30 positivity, proliferation index, large-cell transformation, WBC/lymphocyte count, serum lactate dehydrogenase, and identical T-cell clone in blood and skin. Data were collected at specialist centers on patients diagnosed with advanced-stage MF/SS from 2007. Each parameter recorded at diagnosis was tested against overall survival (OS). Results Staging data on 1,275 patients with advanced MF/SS from 29 international sites were included for survival analysis. The median OS was 63 months, with 2- and 5-year survival rates of 77% and 52%, respectively. The median OS for patients with stage IIB disease was 68 months, but patients diagnosed with stage III disease had slightly improved survival compared with patients with stage IIB, although patients diagnosed with stage IV disease had significantly worse survival (48 months for stage IVA and 33 months for stage IVB). Of the 10 variables tested, four (stage IV, age > 60 years, large-cell transformation, and increased lactate dehydrogenase) were independent prognostic markers for a worse survival. Combining these four factors in a prognostic index model identified the following three risk groups across stages with significantly different 5-year survival rates: low risk (68%), intermediate risk (44%), and high risk (28%). Conclusion To our knowledge, this study includes the largest cohort of patients with advanced-stage MF/SS and identifies markers with independent prognostic value, which, used together in a prognostic index, may be useful to stratify advanced-stage patients.

The stroke volume among black ischemic stroke patients in phase I of the population-based Greater Cincinnati/Northern Kentucky Stroke Study (GCNKSS) was smaller than reported among acute stroke studies, with a median stroke volume of 2.5 cm. However, it is not known if stroke volume was similar between black and white patients within the same study population. Phase II of the GCNKSS identified all ischemic strokes between July 1993 and June 1994. The stroke volume was estimated by study physicians using the modified ellipsoid method. Analysis of stroke volume by race, sex and age was performed for strokes with a measurable lesion of >or=0.5 cm(3). Among verified cases of ischemic stroke, 334 patients were eligible for this analysis. There were 191 whites (57%) and 143 blacks (43%). The mean age was 69.4 years. The median stroke volume for all patients was 8.8 cm(3) (range 0.5-540), with a mean of 36.4 cm(3). Stroke volume was not different between men and women, and it tended to increase with age. Although stroke volume was significantly higher among whites, age was a confounding factor. Subsequent analysis of stroke volume stratified by age showed no difference between blacks and whites in any age group. Our data show that most ischemic stroke lesions, regardless of the race, are of small size, and this may be an important reason for the low percentage of strokes treated currently with tissue-type plasminogen activator. The association of age with stroke volume requires further study. Copyright 2008 S. Karger AG, Basel.

An Economic Opportunity Survey was conducted on dairy farms in the North West Province of Cameroon. Results showed that median (range) number of cows in milk per farm was zero point six (0-4) and six (3-12) in the zero grazing and transhumance systems, respectively. Medians (range) of three (0-24) and four (3-10) litres of milk were sold per farm per day, corresponding to 30% and 60% of milk produced. 24% and 13% of total cattle per herd were milking cows in the zero grazing and transhumance systems respectively. Median milk production per cow on one day was two (0-25) and two (1-3) litres. Median calf production interval was 14.5 (12-25) and. 21.5 (14-29) months. More milk produced per day represented the best economic opportunity in both systems while reduced age at first calving and longer lactation length were the next in both. Wastage of milk through spoilage from poor hygiene and lack of cooling was a major problem. Holstein cows, which were in the zero grazing system, had unexpectedly short lactations. Constraints identified led to the setting up of interventions of training and advice for farmers and of better nutrition.

Intussusception (IS) is a form of acute intestinal obstruction that occurs mainly in infants and is usually of unknown cause. An association between IS and the first licensed rotavirus vaccine, a reassortant-tetravalent, rhesus-based rotavirus vaccine (RRV-TV), led to the withdrawal of the vaccine. New rotavirus vaccines have now been developed and extensively studied for their potential association with IS. This study aimed to describe the epidemiology and to estimate the incidence of IS in Latin American infants prior to new vaccine introduction. Children under 2 years of age representing potential IS cases were enrolled in 16 centers in 11 Latin American countries from January 2003 to May 2005. IS cases were classified as definite, probable, possible or suspected as stated on the Brighton Collaboration Working Group guidelines. From 517 potential cases identified, 476 (92%) cases were classified as definite, 21 probable, 10 possible and 10 suspected for intussusception. Among the 476 definite IS cases, the median age at presentation was 6.4 months with 89% of cases aged <1 year. The male to female ratio was 1.5:1. The incidence of definite IS per 100,000 subject-years ranged from 1.9 in Brazil to 62.4 in Argentina for children <2 years of age, and from 3.8 in Brazil to 105.3 in Argentina for children aged <1 year. Median hospital stay was 4 days with a high prevalence of surgery as the primary treatment (65%). Most cases (88%) made a complete recovery, but 13 (3%) died. No clear seasonal pattern of IS cases emerged. This study describes the epidemiology and estimates the incidence of IS in Latin American infants prior to the introduction of new rotavirus vaccines. The incidence of IS was found to vary between different countries, as observed in previous studies. Clinical study identifier 999910/204 (SERO-EPI-IS-204).

There is a well-established research base surrounding face recognition in patients with age-related macular degeneration (AMD). However, much of this existing research does not differentiate between results obtained for 'wet' AMD and 'dry' AMD. Here, we test the hypothesis that face recognition performance is worse in patients with dry AMD compared with visually healthy peers. Patients (>60 years of age, logMAR binocular visual acuity 0.7 or better) with dry AMD of varying severity and visually healthy age-related peers (controls) completed a modified version of the Cambridge Face Memory Test (CFMT). Percentage of correctly identified faces was used as an outcome measure for performance for each participant. A 90% normative reference limit was generated from the distribution of CFMT scores recorded in the visually healthy controls. Scores for AMD participants were then specifically compared to this limit, and comparisons between average scores in the AMD severity groups were investigated. Thirty patients (median [interquartile range] age of 76 [70, 79] years) and 34 controls (median age of 70 [64, 75] years) were examined. Four, seventeen and nine patients were classified as having early, intermediate and late AMD (geographic atrophy) respectively. Five (17%) patients recorded a face recognition performance worse than the 90% limit (Fisher's exact test, p = 0.46) set by controls; four of these had geographic atrophy. Patients with geographic atrophy identified fewer faces on average (±SD) (61% ± 22%) than those with early and intermediate AMD (75 ± 11%) and controls (74% ± 11%). People with dry AMD may not suffer from problems with face recognition until the disease is in its later stages; those with late AMD (geographic atrophy) are likely to have difficulty recognising faces. The results from this study should influence the management and expectations of patients with dry AMD in both community practice and hospital clinics.

Stereotactic body radiation therapy (SBRT) represents a promising treatment option for patients with localized pancreatic ductal adenocarcinoma (PDAC) who cannot tolerate surgical therapy. We retrospectively reviewed the records of patients with localized PDAC treated with SBRT at our institution between 2010 and 2016 to identify patients deemed medically inoperable due to poor performance status, advanced age, and/or comorbid conditions. Overall survival (OS), progression-free survival (PFS), and local progression-free survival (LPFS) were estimated using Kaplan-Meier curves. Twenty-nine patients were included. Median age was 74 (IQR 68-79). Thirteen patients (45%) had an Eastern Cooperative Oncology Group performance status of 2. Six patients (19%) had chronic obstructive pulmonary disease, 9 (31%) had cardiovascular disease, and 17 (58%) had diabetes mellitus. SBRT was delivered over 5 fractions to a median dose of 28 Gy (IQR, 25-33). Twenty-two patients (76%) received induction chemotherapy prior to SBRT, and 9 (31%) received maintenance chemotherapy after SBRT. Median OS was 13 months from diagnosis. Median OS and PFS were 8 and 6 months from SBRT, respectively. Six and 12-month LPFS rates were 91% and 78%, respectively. Patients receiving induction chemotherapy had superior survival from diagnosis than those who did not (14 vs. 7 months, p = 0.01). Three patients (10%) experienced acute grade ≥3 toxicity, and 1 patient (4%) experienced grade ≥3 late toxicity. Symptom relief was achieved at three-month follow-up in 8 of 11 patients (73%) experiencing abdominal pain. These results suggest SBRT may be safe and effective for patients who cannot tolerate surgery.

The burden of disease in children with non-cystic fibrosis (non-CF) bronchiectasis is unknown. Our study aimed to identify the determinants of quality of life (QOL) and parental mental health in this group of patients and their parents and to evaluate the effect of exacerbations on these parameters. Parents of 69 children (median age 7 years) with non-CF bronchiectasis prospectively completed two questionnaires (parent-proxy cough-specific quality of life [PC-QOL] and the Depression, Anxiety, and Stress Scale [DASS]) at stable and exacerbation states. Data on clinical, investigational, and lung function parameters were also collected. During the stable state, the median interquartile range (IQR) PC-QOL score was 6.5 (5.3-6.9) and the DASS 21-item questionnaire score was 6 (0-20). Being of a young age correlated with a worse QOL (r(5) = 0.242, P = .04) but radiologic extent, lung function, underlying cause, environmental tobacco smoke exposure, and chronic upper-airway disease did not influence these scores. Exacerbations caused significant worsening in the PC-QOL scores (median [IQR], 4.6 [3.8-5.4]; P = .001) and DASS scores (median [IQR], 22 [9-42]; P < .001; 38% with elevated anxiety, 54% with abnormal depression/stress scores during exacerbation). The presence of viral infection, hypoxia, and hospitalization did not influence the exacerbation PC-QOL and DASS scores. There is a significant burden of disease, especially during exacerbation, on parents of children with bronchiectasis. Prevention, early detection, and appropriate treatment of exacerbations are likely to reduce psychologic morbidity in this group.

Before the introduction of rotavirus vaccine in Egypt, information on the burden of disease and the circulating rotavirus genotypes is critical to monitor vaccine effectiveness. A cohort of 348 Egyptian children was followed from birth to 2 years of age with twice-weekly home visits to detect diarrheal illness. VP7 and VP4 genes were genotyped by reverse-transcription polymerase chain reaction and DNA sequencing. Forty percentage of children had rotavirus-associated diarrhea at least once by their second birthday. One hundred and twelve children experienced a single rotavirus diarrheal episodes (RDE) at a median age of 9 months; while 27 infants had their second RDE at a median age of 15 months and 1 infant had 3 RDE at the age of 2, 16 and 22 months. Of the 169 RDE, 82% could be assigned a G-type, while 58% had been identified a P-type. The most prevalent genotype was G2 (32%), followed by G1 (24%) and G9 (19%). G2P[4] rotavirus episodes were significantly associated with fever (P = 0.03) and vomiting (P = 0.06) when compared with other genotypes. G2 strains were the predominant genotype causing 50% of the second RDE while G9 represented 25% of the second RDE. Genotypes identified are similar to those detected globally except for absence of G4. Our finding that 75% of the second RDE were due to G2 and G9 indicates a possible reduction in natural protection afforded by these types compared with G1, where 90% of G1 cases did not experience a second xposure, indicating greater protection against recurrent symptomatic infection.

Sudden unexpected death in epilepsy is a major cause of premature death in people with epilepsy. We aimed to assess whether structural changes potentially attributable to sudden death pathogenesis were present on magnetic resonance imaging in people who subsequently died of sudden unexpected death in epilepsy. In a retrospective, voxel-based analysis of T1 volume scans, we compared grey matter volumes in 12 cases of sudden unexpected death in epilepsy (two definite, 10 probable; eight males), acquired 2 years [median, interquartile range (IQR) 2.8] before death [median (IQR) age at scanning 33.5 (22) years], with 34 people at high risk [age 30.5 (12); 19 males], 19 at low risk [age 30 (7.5); 12 males] of sudden death, and 15 healthy controls [age 37 (16); seven males]. At-risk subjects were defined based on risk factors of sudden unexpected death in epilepsy identified in a recent combined risk factor analysis. We identified increased grey matter volume in the right anterior hippocampus/amygdala and parahippocampus in sudden death cases and people at high risk, when compared to those at low risk and controls. Compared to controls, posterior thalamic grey matter volume, an area mediating oxygen regulation, was reduced in cases of sudden unexpected death in epilepsy and subjects at high risk. The extent of reduction correlated with disease duration in all subjects with epilepsy. Increased amygdalo-hippocampal grey matter volume with right-sided changes is consistent with histo-pathological findings reported in sudden infant death syndrome. We speculate that the right-sided predominance reflects asymmetric central influences on autonomic outflow, contributing to cardiac arrhythmia. Pulvinar damage may impair hypoxia regulation. The imaging findings in sudden unexpected death in epilepsy and people at high risk may be useful as a biomarker for risk-stratification in future studies. PMID:26264515

To evaluate the process of combined orthognathic and orthodontic care. To identify factors that affect treatment time and percentage Peer Assessment Rating (PAR) reduction, and the PAR efficiency factor for such cases. Retrospective multi centre study of patients who underwent orthognathic treatment in the East of England region. Analysis of consecutive cases that underwent orthognathic surgery in 2008. Inclusion criteria included pre- and post-surgery orthodontic treatment. Ten orthodontic units submitted data for a total of 118 patients. Within the sample, 64% were class III, 35% class II/1 and 1% class II/2. Overall extraction rate, excluding third molars, was 58%. Median age at bond up was 17 years. Mean total number of orthodontic attendances was 23. Median length of pre-surgical orthodontics was 23 months and post-surgical orthodontics was 7 months. Median length of total treatment was 29 months. Mean wait for surgery was 3·6 months. Diagnosis of incisor relationship and skeletal base, transfer of operator, total number of visits, tooth extraction and treatment unit affected treatment duration. Median pre- and post-treatment PAR scores were 43 and 4, respectively. Median change in PAR score was 38·5. Median per cent reduction in PAR was 90·6%. The median PAR efficiency factor (reduction in PAR score divided by treatment time in months) was 1·24. Diagnosis of incisor relationship and skeletal base correlated with percentage reduction in PAR score. Combined orthognathic treatment was effective. Factors affecting treatment duration and percentage reduction in PAR have been established.

Non-ischaemic cardiomyopathy (NIC) is an early complication of liver transplantation (LT). Our aims were to define the prevalence, associated clinical factors, and prognosis of this condition. A retrospective study was performed on patients undergoing LT at our institution from January 2005 to December 2012. Patients who developed NIC were identified. Data collected included demographic and clinical data. A total 1460 transplants were performed in this period and seventeen patients developed NIC. Pretransplant median QTc interval was 459 (range, 405-530), and median E/A ratio was 1 (range, 0.71-1.67). Fourteen patients (82%) were severely malnourished and required nutritional support. Thirteen patients (76%) had renal insufficiency. Median time to onset was 2 days post-transplant (range, 0-20). Echocardiograms showed global left ventricular hypokinesis and a decrease in ejection fraction (EF) from a median of 65% (range, 50-81) pretransplant to a median of 21% (range, 15-32). Median raw model for end-stage liver disease (MELD) score was 29 in patients with NIC vs. 18 in patients without cardiomyopathy (P = 0.01). There was no significant difference between recipients with NIC vs. recipients without cardiomyopathy regarding donor age, donor risk index, and cold and warm ischaemia time. Recovery of cardiac function occurred in 16 patients, with a median EF of 44% (range, 25-65%) at the time of discharge. The last echocardiogram available showed a median EF of 59% (range, 49-73%). One-year survival of NIC patients was 94.1%. Non-ischaemic cardiomyopathy is a rare complication after LT. Patients with NIC are critically ill, with high MELD score, and severe malnutrition. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The study aimed to describe the age distribution of breast cancer diagnosis among Chinese females for comparison with the United States and the European Union, and provide evidence for the screening target population in China. Median age was estimated from hospital databases from 7 tertiary hospitals in China. Population-based data in China, United States and European Union was extracted from the National Central Cancer Registry, SEER program and GLOBOCAN 2008, respectively. Age-standardized distribution of breast cancer at diagnosis in the 3 areas was estimated based on the World Standard Population 2000. The median age of breast cancer at diagnosis was around 50 in China, nearly 10 years earlier than United States and European Union. The diagnosis age in China did not vary between subgroups of calendar year, region and pathological characteristics. With adjustment for population structure, median age of breast cancer at diagnosis was 50~54 in China, but 55~59 in United States and European Union. The median diagnosis age of female breast cancer is much earlier in China than in the United States and the European Union pointing to racial differences in genetics and lifestyle. Screening programs should start at an earlier age for Chinese women and age disparities between Chinese and Western women warrant further studies.

Human rhinoviruses and enteroviruses in influenza-like illness in Latin America

PubMed Central

2013-01-01

Background Human rhinoviruses (HRVs) belong to the Picornaviridae family with high similarity to human enteroviruses (HEVs). Limited data is available from Latin America regarding the clinical presentation and strains of these viruses in respiratory disease. Methods We collected nasopharyngeal swabs at clinics located in eight Latin American countries from 3,375 subjects aged 25 years or younger who presented with influenza-like illness. Results Our subjects had a median age of 3 years and a 1.2:1.0 male:female ratio. HRV was identified in 16% and HEV was identified in 3%. HRVs accounted for a higher frequency of isolates in those of younger age, in particular children < 1 years old. HRV-C accounted for 38% of all HRVs detected. Phylogenetic analysis revealed a high proportion of recombinant strains between HRV-A/HRV-C and between HEV-A/HEV-B. In addition, both EV-D68 and EV-A71 were identified. Conclusions In Latin America as in other regions, HRVs and HEVs account for a substantial proportion of respiratory viruses identified in young people with ILI, a finding that provides additional support for the development of pharmaceuticals and vaccines targeting these pathogens.

To examine the early and late surgical outcomes of feminizing genitoplasty (FG) in adult transsexuals in a UK single surgeon practice over a 10-year period. Computerized and manual databases were searched over the period 1994-2004 to identify patients who had undergone male to female FG. Case-notes were retrieved and analysed to identify epidemiological data, the number and type of perioperative problems, early results at outpatient review, late occurring problems and patient satisfaction. A telephone questionnaire was then conducted targeting all FG patients in our series. The questions were directed at identifying surgical complications, outcome and patient satisfaction. In all, 233 case-notes were identified and 222 (95%) were retrieved. All patients had penectomy, urethroplasty and labiaplasty, 207 (93%) had formation of a neoclitoris, and 202 (91%) had a skin-lined neovagina. The median (range) age was 41 (19-76) years. The median hospital stay was 10 (6-21) days. A record of the first outpatient visit was available in 197 (84.5%) cases. The median time to follow up was 56 (8-351) days. Over all, 82.2% had an adequate vaginal depth, with a median depth of 13 (5-15) cm and 6.1% had developed vaginal stenosis. Three (1.7%) patients had had a vaginal prolapse, two (1.1%) had a degree of vaginal skin flap necrosis and one (0.6%) was troubled with vaginal hair growth. In 86.3% of the patients the neoclitorizes were sensitive. There was urethral stenosis in 18.3% of the patients and 5.6% complained of spraying of urine. Minor corrective urethral surgery was undertaken in 36 patients including 42 urethral dilatations, and eight meatotomies were performed. At the first clinic visit 174 (88.3%) patients were 'happy', 13 (6.6%) were 'unhappy' and 10 (5.1%) made no comment. Of the 233 patients, we successfully contacted 70 (30%). All had had penectomy and labioplasty, 64 (91%) had a clitoroplasty and 62 (89%) a neovagina. The median age was 43 (19-76) years and the median follow up was 36 (9-96) months. Overall, 63 (98%) had a sensate neoclitoris, with 31 (48%) able to achieve orgasm; nine (14%) were hypersensitive. Vaginal depth was considered adequate by 38 (61%) and 14 (23%) had or were having regular intercourse. Vaginal hair growth troubled 18 (29%), four (6%) had a vaginal prolapse and two (3%) had vaginal necrosis. Urinary problems were reported by 19 (27%) patients, of these 18 (26%) required revision surgery, 14 (20%) complained of urinary spraying, 18 (26%) had an upward directed stream and 16 (23%) had urethral stenosis. The patients deemed the cosmetic result acceptable in 53 (76%) cases and 56 (80%) said the surgery met with their expectations. This is largest series of early results after male to female FG. Complications are common after this complex surgery and long-term follow-up is difficult, as patients tend to re-locate at the start of their 'new life' after FG. There were good overall cosmetic and functional results, with a sustained high patient satisfaction.

As more people live longer, age-related neurodegenerative diseases are an increasingly important societal health issue. Treatments targeting specific pathologies such as amyloid beta in Alzheimer’s disease (AD) have not led to effective treatments, and there is increasing evidence of a disconnect between traditional pathology and cognitive abilities with advancing age, indicative of individual variation in resilience to pathology. Here, we generated a comprehensive neuropathological, molecular, and transcriptomic characterization of hippocampus and two regions cortex in 107 aged donors (median = 90) from the Adult Changes in Thought (ACT) study as a freely-available resource (http://aging.brain-map.org/). We confirm established associations between AD pathology and dementia, albeit with increased, presumably aging-related variability, and identify sets of co-expressed genes correlated with pathological tau and inflammation markers. Finally, we demonstrate a relationship between dementia and RNA quality, and find common gene signatures, highlighting the importance of properly controlling for RNA quality when studying dementia.

The size of waiting lists has traditionally been viewed as a fairly good measure of the quality of health care services. No statistical analysis exists in Iceland of the length of waiting times and the potential variation between groups of patients. This study was conducted within the office of the Directorate of Health in Iceland. This location was convenient since standardized information on waiting lists is collected by the office three times a year. Variations in waiting times were studied based on gender on the one hand and on age on the other. Data from the largest waiting lists, those amounting to 400 or more patients, were included in the study. The most frequently awaited operations were identified and the groups of people waiting for them analyzed. The departments and prospective operations included in the study were: Dept. of General Surgery at the University Hospital (UH) (laparoscopic gastro-oesophageal antireflux operation), Opthalmology at UH (phakoemulsification with implantation of artificial lens in posterior chamber), Orthopedic Surgery at UH (primary total prosthetic replacement of hip joint using sement), The Rehabilitation Center at Reykjalundur (rehabilitation, not specified), Ear, Nose and Throat (ENT) at UH (tonsillectomy), and Reconstructive Surgery at UH (reduction mammoplasty with transposition of areola). The lists were sorted by gender and age, with the latter consisting of two categories, older and younger patients. Every attempt was made as to ensure similar sample sizes for both age groups within each department. Finally, the median waiting time was determined and a Mann-Whitney test conducted in order to test for significance. The median waiting time for males at the General Surgery Dept. was 73 weeks as compared to 60 weeks for females. This was the only department where the median waiting time was significantly longer for males than for females (p<0.05). At three of the departments the older group had a longer median waiting time than the younger group, 18 weeks compared to 14 at Opthalmology (p<0.001), 26 versus 17 weeks at Reykjalundur (p<0.025) and 33 versus 21 weeks at ENT (p<0.01). Waiting times for females was significantly longer than for males at two departments, Reykjalundur (21 vs. 17 weeks, p<0.05) and ENT (33 vs. 29 weeks, p<0.05). This study revealed age and gender differences in median waiting times at Icelandic hospitals. These differences were in many cases marked and statistically significant. Various explanations have been put forward, however, further research is needed in order to determine if it these differences are due to actual clinical needs assessments or to age or gender discrimination.

To estimate the mean age at menarche and its association with nutritional status in Brazilian adolescents. The study sample included female adolescents aged 12-17 who participated in a multicenter, school-based, country-wide, cross-sectional study entitled The Study of Cardiovascular Risk in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes [ERICA]). Mean and median ages at menarche in Brazil were estimated. The association of age at menarche with sociodemographic data and nutritional status were described as means and their respective 95% confidence intervals. Survival analysis was used to assess the age at menarche according to nutritional status categories and the log-rank test was used to compare the medians. Bivariate and multivariate analyses were performed using Cox regression to verify the association between menarche and other variables. A total of 73,624 students were evaluated, comprising 40,803 girls, of whom 37,390 reported menarche at a mean age of 11.71 years and a median of 12.41 years. Median age at menarche was lower in overweight and obese girls (p<0.001). The multivariate analysis showed that excess weight (HR=1.28; 95% CI 1.21-1.36; p<0.001) and studying in a private school (HR=1.06; 95% CI 1.02-1.10; p=0.003) were associated with menarche. This is a pioneering study in Brazil with national and regional representativeness to estimate the mean and the median age of occurrence of menarche. Adolescents with excess weight had an earlier menarche than their peers, even after adjustment for confounding factors. Copyright © 2018 Sociedade Brasileira de Pediatria.

Functional constipation (FC) is a common gastrointestinal (GI) problem affecting children's well-being and quality of life. Although polyethylene glycol (PEG) is recommended as the first line therapy, it is not always applicable in lower socioeconomic populations. Hence, this study aimed to compare clinical courses of FC in children treated with different medications in order to identify prognostic factors related to treatment outcomes. We reviewed the medical records of patients aged ≤15 years diagnosed with FC according to the Rome IV criteria from 2007 to 2015 at the GI clinic, Songklanagarind Hospital. Baseline characteristic, medical history, and treatment outcomes were collected at first and subsequent visits. Exactly 104 patients (median age at diagnosis, 2.8 years) were diagnosed with FC. The number of follow-up visits per patient ranged from 1 to 35. The median duration of follow-up was 18.0 months (range, 6.0-84.2 months). PEG was given to 21% of patients. During the follow up period, 76% of patients experienced first recovery with a median time to recovery of 9.8 months. There were no significant differences in time until first recovery and relapse between patients who received and those who did not receive PEG ( p =0.99 and 0.06, respectively). Age >6 years, normal defecation frequency, no history of cow's milk protein allergy, and use of laxatives were associated with successful outcomes. Treatment outcomes between patients who had and never had PEG demonstrated no significant difference in our study. Hence, current practices in laxative prescriptive patterns may be effective.

Objective The purpose of this study was to examine the timing of early intervention diagnostic and therapeutic services in cochlear implant recipients from rural and urban areas. Study design Retrospective case series review Setting Tertiary referral center Patients Cochlear implant recipients from a single comprehensive hearing institute born with severe congenital sensorineural hearing loss were examined. Timing of diagnostic and therapeutic services was examined. Intervention(s) Diagnosis, amplification, and eventual cochlear implantation for all patients in the study Main outcome measure(s) Time points of definitive diagnosis, amplification, and cochlear implantation for children from urban and rural regions were examined. Correlation analysis of distance to testing center and timing of services was also assessed. Results 40 children born with congenital hearing loss were included in the study and were diagnosed at a median age of 13 weeks after birth. Children from rural regions obtained amplification at a median age of 47.7 weeks after birth, while urban children were amplified at 26 weeks after birth. Cochlear implantation was performed at a median age of 182 weeks after birth in those from rural areas and at 104 weeks after birth in urban-dwelling patients. A linear relationship was identified between distance to the implant center and timing of hearing aid amplification (r=0.5, p=0.033) and cochlear implantation (r=0.5, p=0.016). Conclusions Children residing outside of metro areas may be at higher risk of delayed rehabilitative services and cochlear implantation than those residing in urban areas that may be closer in proximity to tertiary care centers.

Background Little is known about the management of patients suffering from chronic obstructive pulmonary disease (COPD) during the last years of life. The aim of the study was to describe how management of COPD is performed in Sweden during the last two years of life. Methods From the nationwide Cause of Death register all individuals with COPD as the underlying cause of death during two years were identified in one sparsely and one densely populated area of Sweden. Data were collected from medical records using a pre-defined protocol, especially developed for this purpose. Results Of 822 individuals with COPD as underlying cause of death, medical records from 729 were available. The COPD diagnosis was based on lung function measurements in approximately half of the patients and median age at COPD diagnosis was 74 years (range 34-95). Women died at younger age, median 78 years (range 52-96) than did men (80 years (51-99)). The median survival time from diagnosis to death was 6 years in men and women in both areas. Among women and men 8.3% and 4.3% were never smokers, respectively. The structure of COPD management differed between the two areas, with utilization of physiotherapists, dieticians and working therapists being more used in the northern area, likely because of differences in accessibility to care institutions. Conclusions In Sweden COPD is mostly diagnosed late in life and often not verified by lung function measurements. Opposite to the general population, women with COPD die at a lower age than men.

Case Series Analysis of New Zealand Reports of Rapid Intense Potentiation of Warfarin by Roxithromycin.

Savage, Ruth L; Tatley, Michael V

2018-05-01

We undertook an analysis of all the reports to the New Zealand Centre for Adverse Reactions Monitoring of a roxithromycin/warfarin interaction after two recent reports described intense rapid warfarin potentiation. The interaction was first published in 1995. Cytochrome P450 3A4 inhibition has been the proposed mechanism but has limited biologic plausibility. There are suggestions that the clinical significance of the interaction may be increased by severe illness, polypharmacy, renal dysfunction, older age and increased warfarin sensitivity. To investigate the potentiating effect of warfarin on roxithromycin in this New Zealand case series, the reports were reviewed to identify patients at risk, compare the reporting pattern with published Australian data and evaluate the appropriateness of current prescribing advice. Thirty patient reports were identified. The age range was 23-88 years, mean 66.8, median 73.0 (standard deviation 17.7) and the international normalised ratios after roxithromycin commencement ranged from 3.6 to 16.7 (mean 7.6, median 7.6, standard deviation 3.6). For eight patients with measurements on day 3, international normalised ratios were 4.3-16.7 (mean 10.4, median 8.8, standard deviation 4.4). Four patients had serious haemorrhage. Indications for roxithromycin were a range of respiratory tract infections. Anticoagulation was stable for most patients prior to acute infection. Serious infection occurred in 54.5% (12 of 22 patients with information). Polypharmacy (five or more medicines daily) was used by 36.7% of patients long term, increasing acutely to 83.3%, including additional potentially interacting medicines. Warfarin daily dose (1.5-13.0 mg, mean 4.4, median 4.0, standard deviation 2.2) was moderate to low. Pre-roxithromycin international normalised ratio values ranged from 1.4 to 3.7, mean and median 2.5, standard deviation 0.5. A high proportion of interactions were observed between warfarin and roxithromycin compared with other macrolides and compared with cytochrome P450 3A4-related macrolide interactions. The pattern was similar to published Australian data. In this case series, the high prevalence of acute polypharmacy, including potentially interacting medicines, and serious infection suggests that they may have contributed to warfarin potentiation and increased the clinical significance of a roxithromycin/warfarin interaction.

To assess whether children ≤5 years of age, produce sufficient amounts of interferon gamma (IFN-ɣ) in response to phytohaemagglutinin (mitogen), and Mycobacterium tuberculosis antigens (TB antigens) in the QuantiFERON-TB Gold in-Tube test (QFT-GIT), (Cellestis Ltd., Australia). Is TB-antigen-induced IFN-ɣ response in children ≤5 years sufficient to consider QFT-GIT a possible tool for TB diagnostics? Study design, patient-subject selection, and methods: We recruited children 0-17 years old suspected of TB infection to this cross-sectional study, in whom QFT-GIT and TST were performed. We analyzed the median IFN-ɣ levels in mitogen and TB antigen tubes in children ≤5 years and >5 years, and the correlation between IFN-ɣ level in both tubes and age. A total of 153 children were enrolled, age median was 7.8 (IQR:8), 45 (29.4%) aged ≤5 years (median 3.4, IQR:1.7), 108 > 5 years (median 10.55, IQR:5.93). In the mitogen tubes, the median IFN-ɣ level was higher in children >5 years (median 17.87, IQR:2.1 vs 16.77, IQR:7.6), but surprisingly in the TB antigen tubes it was higher in the younger group (median 0.12, IQR:0.21vs 0.06, IQR:0.09, P = 0.04). We proved a positive correlation between IFN-ɣ level and age in mitogen tubes (r = 0.18, P = 0.03) and a negative correlation in TB antigen tubes (r = -0.17, P = 0.04). In latent tuberculosis infection patients, the latter correlation was found to be even stronger (r = -0.39, P = 0.01). The youngest children release sufficient amount of IFN-ɣ in response to TB antigens thus QFT-GIT might be a useful tool for TB diagnostics in this age group. © 2017 Wiley Periodicals, Inc.

This study was conducted to better understand the characteristics of chronic pain patients seeking treatment with medicinal cannabis (MC). Retrospective chart reviews of 139 patients (87 males, median age 47 years; 52 females, median age 48 years); all were legally qualified for MC use in Washington State. Regional pain clinic staffed by university faculty. age 18 years and older; having legally accessed MC treatment, with valid documentation in their medical records. All data were de-identified. Records were scored for multiple indicators, including time since initial MC authorization, qualifying condition(s), McGill Pain score, functional status, use of other analgesic modalities, including opioids, and patterns of use over time. Of 139 patients, 15 (11 percent) had prior authorizations for MC before seeking care in this clinic. The sample contained 236.4 patient-years of authorized MC use. Time of authorized use ranged from 11 days to 8.31 years (median of 1.12 years). Most patients were male (63 percent) yet female patients averaged 0.18 years longer authorized use. There were no other gender-specific trends or factors. Most patients (n = 123, 88 percent) had more than one pain syndrome present. Myofascial pain syndrome was the most common diagnosis (n = 114, 82 percent), followed by neuropathic pain (n = 89, 64 percent), discogenic back pain (n = 72, 51.7 percent), and osteoarthritis (n = 37, 26.6 percent). Other diagnoses included diabetic neuropathy, central pain syndrome, phantom pain, spinal cord injury, fibromyalgia, rheumatoid arthritis, HIV neuropathy, visceral pain, and malignant pain. In 51 (37 percent) patients, there were documented instances of major hurdles related to accessing MC, including prior physicians unwilling to authorize use, legal problems related to MC use, and difficulties in finding an affordable and consistent supply of MC. Data indicate that males and females access MC at approximately the same rate, with similar median authorization times. Although the majority of patient records documented significant symptom alleviation with MC, major treatment access and delivery barriers remain.

AIM: To evaluate the effectiveness of barium impaction therapy for patients with colonic diverticular bleeding. METHODS: We reviewed the clinical charts of patients in whom therapeutic barium enema was performed for the control of diverticular bleeding between August 2010 and March 2012 at Yokohama Rosai Hospital. Twenty patients were included in the review, consisting of 14 men and 6 women. The median age of the patients was 73.5 years. The duration of the follow-up period ranged from 1 to 19 mo (median: 9.8 mo). Among the 20 patients were 11 patients who required the procedure for re-bleeding during hospitalization, 6 patients who required it for re-bleeding that developed after the patient left the hospital, and 3 patients who required the procedure for the prevention of re-bleeding. Barium (concentration: 150 w%/v%) was administered per the rectum, and the leading edge of the contrast medium was followed up to the cecum by fluoroscopy. After confirmation that the ascending colon and cecum were filled with barium, the enema tube was withdrawn, and the patient’s position was changed every 20 min for 3 h. RESULTS: Twelve patients remained free of re-bleeding during the follow-up period (range: 1-19 mo) after the therapeutic barium enema, including 9 men and 3 women with a median age of 72.0 years. Re-bleeding occurred in 8 patients including 5 men and 3 women with a median age of 68.5 years: 4 developed early re-bleeding, defined as re-bleeding that occurs within one week after the procedure, and the remaining 4 developed late re-bleeding. The DFI (disease-free interval) decreased 0.4 for 12 mo. Only one patient developed a complication from therapeutic barium enema (colonic perforation). CONCLUSION: Therapeutic barium enema is effective for the control of diverticular hemorrhage in cases where the active bleeding site cannot be identified by colonoscopy. PMID:25987779

Reproductive success was relatively consistent, and adequate to maintain species abundance at a nearly constant level, during 1963-69. Both abundance and growth in length increased from the lower to the upper portion of the reservoir. In most characteristics -- growth in length, length-weight relation, age at maturity, and food -- goldeye in Lake Oahe were similar to those from other Missouri River impoundments. Experimental gill nets samples all lengths (range 80-460 mm; median, 320 mm) of goldeye, bottom trawls sampled mostly small fish, (median, 215 mm) and trap nets large ones (median, 345 mm). Commercial gill nets were highly size selective (median, 375 mm); fish of ages IV-VII made up 90% of the catch. Survival rates were 57 to 52% for ages II-X. Estimated survival rates for ages V-IX declined from 44 to 35% after the inception of the commercial fishery in 1966. The peak commercial catch was 151,432 kg (1.2 kg/hectare) in 1969. Unless recruitment declines, the population can support a fishery of that magnitude.

We present a model for longitudinal measures of fetal weight as a function of gestational age. We use a linear mixed model, with a Box-Cox transformation of fetal weight values, and restricted cubic splines, in order to flexibly but parsimoniously model median fetal weight. We systematically compare our model to other proposed approaches. All proposed methods are shown to yield similar median estimates, as evidenced by overlapping pointwise confidence bands, except after 40 completed weeks, where our method seems to produce estimates more consistent with observed data. Sex-based stratification affects the estimates of the random effects variance-covariance structure, without significantly changing sex-specific fitted median values. We illustrate the benefits of including sex-gestational age interaction terms in the model over stratification. The comparison leads to the conclusion that the selection of a model for fetal weight for gestational age can be based on the specific goals and configuration of a given study without affecting the precision or value of median estimates for most gestational ages of interest.

Objective Germline mutations in BRCA1/2 are related to increased lifetime risk of breast and ovarian cancer. While risk-reducing salpingo-oophorectomy reduces the risk for both cancers, loss of fertility is a major concern. A recent study suggested an association of BRCA1 mutation with occult primary ovarian insufficiency. The aim of this study was to determine whether BRCA1/2 mutation carriers have earlier onset of natural menopause than unaffected women. Materials and Methods Caucasian BRCA1/2 carriers (n=382) were identified within the UCSF Breast Cancer Risk Program Registry and compared to non-clinic-based Caucasian women in Northern California (n=765). We compared the two groups regarding median age at natural menopause before and after adjustment for known risk factors, and examined the role of smoking within each group, using the Kaplan-Meier approach for unadjusted analyses and Cox proportional hazards regression analyses for adjusted analyses. Results The median age at natural menopause in BRCA1/2 carriers was significantly earlier than the unaffected sample (50 vs 53years, p-value<0.001). The unadjusted hazard ratio for natural menopause comparing BRCA1/2 carriers to unaffected women was 4.06(95% confidence interval 3.03-5.45), 3.98(2.87-5.53) after adjusting for smoking, parity, and oral contraceptive use. For BRCA1/2 carriers who were current heavy smokers (≥20cigarettes/day), the median age at natural menopause was 46 vs.49years for non-smokers (p-value=0.027). Conclusions BRCA1/2 mutation was associated with significantly earlier age at natural menopause, and heavy smoking compounded this risk. As the relationship between menopause and end of natural fertility is considered fixed, these findings suggest a risk of earlier infertility among BRCA1/2 carriers. PMID:23362014

Patients with craniopharyngioma are at an increased risk for cardio- and cerebrovascular mortality. The metabolic syndrome (MetS) is an important cardiometabolic risk factor, but barely studied in patients with craniopharyngioma. We aimed to investigate the prevalence of and risk factors for the MetS and its components in patients with craniopharyngioma. Cross-sectional study with retrospective data. We studied the prevalence of and risk factors for the MetS and its components in 110 Dutch (median age 47 years, range 18-92) and 68 Swedish (median age 50 years, range 20-81) patients with craniopharyngioma with ≥3 years of follow-up (90 females (51%); 83 patients with childhood-onset craniopharyngioma (47%); median follow-up after craniopharyngioma diagnosis 16 years (range 3-62)). In Dutch patients aged 30-70 years and Swedish patients aged 45-69 years, we examined the prevalence of the MetS and its components relative to the general population. Sixty-nine (46%) of 149 patients with complete data demonstrated the MetS. Prevalence of the MetS was significantly higher in patients with craniopharyngioma compared with the general population (40% vs 26% ( P  < 0.05) for Dutch patients; 52% vs 15% ( P  < 0.05) for Swedish patients). Multivariable logistic regression analysis identified visual impairment as a borderline significant predictor of the MetS (OR 2.54, 95% CI 0.95-6.81; P  = 0.06) after adjustment for glucocorticoid replacement therapy and follow-up duration. Age, female sex, tumor location, radiological hypothalamic damage, 90 Yttrium brachytherapy, glucocorticoid replacement therapy and follow-up duration significantly predicted components of the MetS. Patients with craniopharyngioma are at an increased risk for the MetS, especially patients with visual impairment. © 2018 European Society of Endocrinology.

Background Few studies have quantified social mixing in remote rural areas of developing countries, where the burden of infectious diseases is usually the highest. Understanding social mixing patterns in those settings is crucial to inform the implementation of strategies for disease prevention and control. We characterized contact and social mixing patterns in rural communities of the Peruvian highlands. Methods and Findings This cross-sectional study was nested in a large prospective household-based study of respiratory infections conducted in the province of San Marcos, Cajamarca-Peru. Members of study households were interviewed using a structured questionnaire of social contacts (conversation or physical interaction) experienced during the last 24 hours. We identified 9015 reported contacts from 588 study household members. The median age of respondents was 17 years (interquartile range [IQR] 4–34 years). The median number of reported contacts was 12 (IQR 8–20) whereas the median number of physical (i.e. skin-to-skin) contacts was 8.5 (IQR 5–14). Study participants had contacts mostly with people of similar age, and with their offspring or parents. The number of reported contacts was mainly determined by the participants’ age, household size and occupation. School-aged children had more contacts than other age groups. Within-household reciprocity of contacts reporting declined with household size (range 70%-100%). Ninety percent of household contact networks were complete, and furthermore, household members' contacts with non-household members showed significant overlap (range 33%-86%), indicating a high degree of contact clustering. A two-level mixing epidemic model was simulated to compare within-household mixing based on observed contact networks and within-household random mixing. No differences in the size or duration of the simulated epidemics were revealed. Conclusion This study of rural low-density communities in the highlands of Peru suggests contact patterns are highly assortative. Study findings support the use of within-household homogenous mixing assumptions for epidemic modeling in this setting. PMID:25734772

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy. FPIES diagnosis is frequently delayed because of the absence of classic allergic symptoms and lack of biomarkers. We sought to characterize the clinical features and resolution of FPIES in patients evaluated in our practice. Subjects 6 months to 45 years of age with FPIES were prospectively recruited for oral food challenges (OFCs). Medical records were searched to identify the subjects who did not participate in OFCs. Among 160 subjects, 54% were male; median age at diagnosis was 15 months. We performed 180 OFCs to 15 foods in 82 subjects; 30% of the study population had FPIES confirmed based on OFC results. The most common foods were cow's milk (44%), soy (41%), rice (22.5%), and oat (16%). The majority (65%) reacted to 1 food, 26% reacted to 2 foods, and 9% reacted to 3 or more foods. The majority were atopic, and 39% had IgE sensitization to another food. Thirty-nine (24%) subjects had positive specific IgE levels to the food inducing FPIES. Among children with specific IgE to cow's milk, 41% changed from a milk FPIES to an IgE-mediated phenotype over time. The median age when tolerance was established was 4.7 years for rice, 4 years for oat, and 6.7 years for soy. Median age when milk tolerance was established for subjects with undetectable milk-specific IgE levels was 5.1 years, whereas none of the subjects with detectable milk-specific IgE became tolerant to milk during the study (P = .003). FPIES typically resolves by age 5 years. Milk FPIES, especially with detectable food-specific IgE, can have a protracted course and eventually transition to acute reactions. Copyright © 2014.

The aim was to determine the proportions and correlates of essential hypertension among children in a tertiary pediatric hypertension clinic. We evaluated 423 consecutive children and collected demographic and clinical history by retrospective chart review. We identified 275 (65%) hypertensive children (blood pressure >95th percentile per the "Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents") from 423 children referred to the clinic for history of elevated blood pressure. The remainder of the patients had normotension (11%), white coat hypertension (11%), prehypertension (10%), and pending diagnosis (3%). Among the 275 hypertensive children, 43% (n = 119; boys = 56%; median age = 12 years; range = 3-17 years) had essential hypertension and 57% (n = 156; boys = 66%; median age = 9 years; range = 0.08-19 years) had secondary hypertension. When compared with those with secondary hypertension, those with essential hypertension had a significantly older age at diagnosis (P = 0.0002), stronger family history of hypertension (94% vs. 68%; P < 0.0001), and lower prevalence of preterm birth (20% vs. 46%; P < 0.001). There was a bimodal distribution of age of diagnosis in those with secondary hypertension. The phenotype of essential hypertension can present as early as 3 years of age and is the predominant form of hypertension in children after age of 6 years. Among children with hypertension, those with essential hypertension present at an older age, have a stronger family history of hypertension, and have lower prevalence of preterm birth. © American Journal of Hypertension, Ltd 2014.

IRA balances and contributions: an overview of the EBRI IRA database.

PubMed

Copeland, Craig

2010-09-01

NEW IRA DATABASE: The Employee Benefit Research Institute created the EBRI IRA Database in order to more closely examine retirement savings behavior. The EBRI IRA Database is able to link individuals within and across the data providers and will also be able to link the data with participants in 401(k) plans, allowing retirement funds to be tracked as they are generated, rolled over, and ultimately used. This Issue Brief is the first of a series of publications analyzing the EBRI IRA Database, and highlights the distribution of IRA owners by IRA type, average and median account balances, and contributions to IRAs. The data security techniques used by the data providers assure that EBRI has no ability to identify individuals so that all privacy is assured. IRA TYPES: In the EBRI IRA Database, IRAs are classified into four types: traditional (originating from contributions), rollovers from other retirement plans, Roth, and SEP/SIMPLE. The distribution of the IRA accounts is 33.6 percent traditional IRAs; 33.4 percent rollover IRAs (combined with the traditional IRAs, 67 percent); 23.4 percent Roth IRAs; the remaining 9.6 percent are SEPs and SIMPLEs. OWNERSHIP BY AGE AND GENDER: IRA owners were more likely to be male, especially those having a rollover or a SEP/SIMPLE IRA. Among all IRA participants in the database, nearly one-half (48.3 percent) were ages 45-64. Only 16.7 percent of those owning a traditional IRA were under age 45, compared with 46.5 percent for those with a Roth, 30.4 percent for rollovers, and 34.8 percent for those with a SEP or SIMPLE. AVERAGE AND MEDIAN BALANCES: The average and median IRA account balance in 2008 was $54,863 and $15,756, respectively, while the average and median IRA individual balance (all accounts from the same person combined) was $69,498 and $20,046, Individuals with a rollover balance had the highest average and median balance at $91,783 and $31,264. Roth owners had the lowest average and median balance at $14,056 and $7,319. The average and median individual IRA balance increased with age before leveling off for those age 70 or older. Averages--The average amount contributed to an IRA in the database was $3,665 in 2008. The average contribution was highest for accounts owned by those ages 65-69. More contributions were made to Roth accounts than to traditional (combined traditional and rollover) accounts. However, the average contribution to a traditional account was higher, at $3,798, compared with $3,580 to a Roth account. Yet, a higher overall amount was contributed to Roth IRAs ($3.4 billion for Roths compared with $2.3 billion for traditional accounts). By type--Focusing only on those owning traditional, rollover, or Roth IRAs, 12.1 percent of the accounts were contributed to, and 15.1 percent of the individuals owning these IRA types contributed to them in 2008. When combining the owners of traditional and rollover IRAs (which are considered the same type for contribution purposes), 7.2 percent contributed, while 29.5 percent of those owning a Roth IRA contributed to a Roth IRA. Maxing out--Of those individuals contributing, 42.4 percent contributed the maximum amount. Of those contributing to a traditional or rollover IRA, 43.4 percent maxed out, while 40.2 percent did so with a Roth IRA.

Mated pairs of northern grasshopper mice, Onychomys leucogaster fuscogriseus, were maintained in a laboratory colony to determine their median longevity, maximum life span, and age-related pathologies. Median life span for both sexes and four cohorts was 1411 days and the maximum life span was 1915 days. There were no significant differences between sexes, but cohorts 5-7 generations removed from wild-caught parents had shorter median life spans. (auth)

The purpose of this study was to evaluate the efficacy and safety of gamma knife radiosurgery (GKRS) for the treatment of symptomatic brainstem intra-axial cavernous malformations (CMs) associated with high surgical morbidity. Twenty-one patients with symptomatic brainstem intra-axial CMs were treated by GKRS between 2005 and 2010. One patient was lost to follow-up. The median age of the patients was 39.5 years (range, 24-69 years). All patients had experienced 1 or more symptomatic hemorrhages before GKRS (range, 1-3). The median marginal radiation dose was 13 Gy, and the median volume of the malformation was 0.56 mL. The median follow-up period after radiosurgery was 32 months (range, 12-82 months; mean, 38.9 months). Before GKRS, 31 hemorrhages (1.55 per patient) were observed. The annual hemorrhage rate before GKRS was 39.5%, excluding the first hemorrhage. After GKRS, 1 hemorrhage (0.05 per patient) was identified. It occurred 6 months after radiosurgery. The patient showed complete recovery to a premorbid status with steroid medication. The annual hemorrhage rate after GKRS was 8.2% for the first 2 years. After the expected latency period, no hemorrhages were identified. One patient (5%) exhibited permanent paresthesia, which was a new neurologic symptom in absence of any hemorrhagic event, after the radiosurgery. GKRS seems to be relatively effective and safe for reducing the rebleeding rate of brainstem intra-axial CMs that have high surgical risk. Careful selection of a low marginal dose and an optimal radiosurgical technique are helpful to achieve good outcomes. Copyright © 2013 Elsevier Inc. All rights reserved.

Immediately calling an ambulance is the key factor in reducing time to hospital presentation for adult stroke. Little is known about prehospital care in childhood arterial ischemic stroke (AIS). We aimed to determine emergency medical services call-taker and paramedic diagnostic sensitivity and to describe timelines of care in childhood AIS. This is a retrospective study of ambulance-transported children aged <18 years with first radiologically confirmed AIS, from 2008 to 2015. Interhospital transfers of children with preexisting AIS diagnosis were excluded. Twenty-three children were identified; 4 with unavailable ambulance records were excluded. Nineteen children were included in the study. Median age was 8 years (interquartile range, 3-14); median Pediatric National Institutes of Stroke Severity Scale score was 8 (interquartile range, 3-16). Emergency medical services call-taker diagnosis was stroke in 4 children (21%). Priority code 1 (lights and sirens) ambulances were dispatched for 13 children (68%). Paramedic diagnosis was stroke in 5 children (26%), hospital prenotification occurred in 8 children (42%), and 13 children (68%) were transported to primary stroke centers. Median prehospital timelines were onset to emergency medical services contact 13 minutes, call to scene 12 minutes, time at scene 14 minutes, transport time 43 minutes, and total prehospital time 71 minutes (interquartile range, 60-85). Emergency medical services call-taker and paramedic diagnostic sensitivity and prenotification rates are low in childhood AIS. © 2017 American Heart Association, Inc.

To identify the prevalence of pulmonary complications in children undergone cardiac surgery, as well as demographic and clinical characteristics of this population. The sample comprised 37 children of both genders, underwent cardiac surgery at the Hospital Universitário Presidente Dutra, São Luis (MA) during the year of 2007. There were not included patients who had lung disease in pre-operative period, patients with neurological disorders, intra-operative death besides lack of data in medical records. The data were obtained from general medical and nursing staff of their medical records. The population of the study was predominantly composed by female children, from the countryside and at school age. Pathologies considered low risk were the majority, especially the patent ductus arteriosus, interventricular communication and interatrial communication. It was observed that the largest share of children made use of cardiopulmonary bypass for more than 30 minutes, with a median of 80 minutes, suffered a median sternotomy, using only the mediastinal drain and made use of mechanical ventilation after surgery, with the median about 6.6 hours. Only three (8.1%) patients developed pulmonary complications, and of these, two died. Most of the sample was female, school aged and from the countryside. The low time of cardiopulmonary bypass and mechanical ventilation, and congenital heart disease with low risk, may have been factors that contributed to the low rate of pulmonary complications postoperative.

Portal hypertension secondary to portal vein obstruction following liver transplant occurs in 5%-10% of children. Jejunal varices are uncommon in this group. We present a case series of children with significant GI blood loss, negative upper endoscopy, and jejunal varices detected by CE. Case series of patients who had CE for chronic GI blood loss following liver transplantation. Three patients who had their initial transplants at a median age of 7 months were identified at our institution presenting at a median age of 8 years (range 7-16 years) with a median Hgb of 2.8 g/dL (range 1.8-6.8 g/dL). Upper endoscopy was negative for significant esophageal varices, gastric varices, and bleeding portal gastropathy in all three children. All three patients had significant jejunal varices noted on CE in mid-jejunum. Jejunal varices were described as large prominent bluish vessels underneath visualized mucosa, one with evidence of recent bleeding. The results led to venoplasty of the portal vein in two patients and a decompressive shunt in one patient with resolution of GI bleed and anemia. CE is useful to diagnose intestinal varices in children with portal hypertension and GI bleeding following liver transplant. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Bladder stones that form in patients with spinal cord injury (SCI) can cause significant morbidity. This study sought to analyze factors associated with bladder stone formation to determine which patients might be at increased risk to develop bladder stones. A review of 56 SCI patients treated for bladder calculi over a 10-year period at a single institution was performed. These patients were compared with a control population of general SCI patients known to be stone free. The factors compared were patient age, duration of injury, level of injury, completeness of injury, method of bladder management, and the presence of documented urinary tract infections with urease-producing organisms. All patients with stones were male and had a median age of 58.5 years. The median level of injury was C6, the median time since injury was 21 years, 66% had complete injuries, 68% managed their bladders with indwelling catheters or suprapubic tubes, and 83% had a history of infections with urease-producing organisms. When compared with the control group, patients forming bladder stones were older (P = 0.03), were more likely to have indwelling catheters (P < 0.0001), had a history of infections with urease-producing organisms (P = 0.04), and had complete injuries (P = 0.018). This information can be used to identify patients who have an increased risk of bladder stones and measures can be taken to reduce their incidence and morbidity.

Objective To evaluate the impact of gentamicin exposure on sensorineural hearing loss (SNHL) in very low birth weight (VLBW) infants. Methods Exposure to gentamicin was determined in infants born between 1993 and 2010 at a gestational age < 32 weeks and/or with a birthweight < 1500 g, who presented with SNHL during the first 5 years of life. For each case, we selected two controls matched for gender, gestational age, birthweight, and year of birth. Results We identified 25 infants affected by SNHL, leading to an incidence of SNHL of 1.58% in our population of VLBW infants. The proportion of infants treated with gentamicin was 76% in the study group and 70% in controls (p = 0.78). The total cumulated dose of gentamicin administered did not differ between the study group (median 10.2 mg/kg, Q1-Q3 1.6–13.2) and the control group (median 7.9 mg/kg, Q1-Q3 0–12.8, p = 0.47). The median duration of gentamicin treatment was 3 days both in the study group and the control group (p = 0.58). Maximum predicted trough serum levels of gentamicin, cumulative area under the curve and gentamicin clearance were not different between cases and controls. Conclusion The impact of gentamicin on SNHL can be minimized with treatments of short duration, monitoring of blood levels and dose adjustment. PMID:27390846

We sought to determine the relationship between relative value units (RVUs) and intended measures of work in catheterization for congenital heart disease. RVU was determined by matching RVU values to Current Procedural Terminology codes generated for cases performed at a single institution. Differences in median case duration, radiation exposure, adverse events, and RVU values by risk category and cases were assessed. Interventional case types were ranked from lowest to highest median RVU value, and correlations with case duration, radiation dose, and a cases-predicted probability of an adverse event were quantified with the Spearman rank correlation coefficient. Between January 2008 and December 2010, 3557 of 4011 cases were identified with an RVU and risk category designation, of which 2982 were assigned a case type. Median RVU values, radiation dose, and case duration increased with procedure risk category. Although all diagnostic cases had similar RVU values (median 10), adverse event rates ranged from 6% to 21% by age group (P < .001). Median RVU values ranged from 9 to 54 with the lowest in diagnostic and biopsy cases and increasing with isolated and then multiple interventions. Among interventional cases, no correlation existed between ranked RVU value and case duration, radiation dose, or adverse event probability (P = .13, P = .62, and P = .43, respectively). Time, skill, and stress inherent to performing catheterization procedures for congenital heart disease are not captured by measurement of RVU alone.

We retrospectively reviewed all the children with right ventricular outflow tract obstruction, hypoplastic pulmonary annulus, and pulmonary arteries who underwent stenting of the right ventricular outflow tract for hypercyanotic spells at our institution between January, 2008 and December, 2013; nine patients who underwent cardiac catheterisation at a median age of 39 days (range 12-60 days) and weight of 3.6 kg (range 2.6-4.3 kg) were identified. The median number of stents placed was one stent (range 1-4). The median oxygen saturation increased from 60% to 96%. The median right pulmonary artery size increased from 3.3 to 5.5 mm (-2.68 to -0.92 Z-score), and the median left pulmonary artery size increased from 3.4 to 5.5 mm (-1.93 to 0 Z-scores). Among all, one patient developed transient pulmonary haemorrhage, and one patient had pericardial tamponade requiring drainage. Complete repair of tetralogy of Fallot +/- atrioventricular septal defect or double-outlet right ventricle was achieved in all nine patients. Transcatheter stent alleviation of the right ventricular outflow tract obstruction resolves hypercyanotic spells and allows reasonable growth of the pulmonary arteries to facilitate successful surgical repair. This represents a viable alternative to placement of a systemic-to-pulmonary artery shunt, particularly in small neonates.

To 1) describe the characteristics and outcomes over time of PICU patients with severe sepsis within the dedicated U.S. children's hospitals, 2) identify patient subgroups at risk for mortality from pediatric severe sepsis, and 3) describe overall pediatric severe sepsis resource utilization. Retrospective review of a prospectively collected multi-institutional children's hospital database. PICUs in 43 U.S. children's hospitals. PICU patients from birth to younger than 19 years were identified with severe sepsis by modified Angus criteria and International Classification of Diseases, 9th Revision, codes for severe sepsis and septic shock. None. Data from the Pediatric Health Information System database collected by the Children's Hospital Association from 2004 to 2012. Pediatric severe sepsis was defined by 1) International Classification of Diseases, 9th Revision, codes reflecting severe sepsis and septic shock and 2) International Classification of Diseases, 9th Revision, codes of infection and organ dysfunction as defined by modified Angus criteria. From 2004 to 2012, 636,842 patients were identified from 43 hospitals. Pediatric severe sepsis prevalence was 7.7% (49,153) with an associated mortality rate of 14.4%. Age less than 1 year (vs age 10 to < 19) (odds ratio, 1.4), underlying cardiovascular condition (odds ratio, 1.4) and multiple organ dysfunction, conferred higher odds of mortality. Resource burden was significant with median hospital length of stay of 17 days (interquartile range, 8-36 d) and PICU length of stay of 7 days (interquartile range, 2-17 d), with median cost/day of $4,516 and median total hospitalization cost of $77,446. There was a significant increase in the severe sepsis prevalence rate from 6.2% to 7.7% from 2004 to 2012 (p < 0.001) and a significant decrease in mortality from 18.9% to 12.0% (p < 0.001). Center mortality was negatively correlated with prevalence (rs = -0.48) and volume (rs = -0.39) and positively correlated with cost (rs = 0.36). In this largest reported pediatric severe sepsis cohort to date, prevalence increased from 2004 to 2012 while associated mortality decreased. Age, cardiovascular comorbidity, and organ dysfunction were significant prognostic factors. Pediatric severe sepsis remains an important cause for PICU admission and mortality and leads to a substantial burden in healthcare costs. Individual center's prevalence and volume are associated with improved outcomes.

Readmission to the hospital within 30 days is a measure of quality care; however, only few modifiable risk factors for 30-day readmission in adults with sickle cell disease are known. We performed a retrospective review of the medical records of adults with sickle cell disease at a tertiary care center, to identify potentially modifiable risk factors for 30-day readmission due to vasoocclusive pain episodes. A total of 88 patients ≥18 years of age were followed for 3.5 years between 2010 and 2013, for 158 first admissions for vasoocclusive pain episodes. Of these, those subsequently readmitted (cases) or not readmitted (controls) within 30 days of their index admissions were identified. Seven risk factors were included in a multivariable model to predict readmission: age, sex, hemoglobin phenotype, median oxygen saturation level, listing of primary care provider, type of health insurance, and number of hospitalized vasoocclusive pain episodes in the prior year. Mean age at admission was 31.7 (18-59) years; median time to readmission was 11 days (interquartile range 20 days). Absence of a primary care provider listed in the electronic medical record (odds ratio 0.38; 95% confidence interval, 0.16-0.91; P = .030) and the number of vasoocclusive pain episodes requiring hospitalization in the prior year were significant risk factors for 30-day readmission (odds ratio 1.30; 95% confidence interval, 1.16-1.44; P <.001). Improved discharge planning and ensuring access to a primary care provider may decrease the 30-day readmission rate in adults with sickle cell disease. Copyright © 2017 Elsevier Inc.

To date, over 150 disease-associated variants in CRB1 have been described, resulting in a range of retinal disease phenotypes including Leber congenital amaurosis and retinitis pigmentosa. Despite this, no genotype-phenotype correlations are currently recognised. We performed a retrospective review of electronic patient records to identify patients with macular dystrophy due to bi-allelic variants in CRB1. In total, seven unrelated individuals were identified. The median age at presentation was 21 years, with a median acuity of 0.55 decimalised Snellen units (IQR = 0.43). The follow-up period ranged from 0 to 19 years (median = 2.0 years), with a median final decimalised Snellen acuity of 0.65 (IQR = 0.70). Fundoscopy revealed only a subtly altered foveal reflex, which evolved into a bull's-eye pattern of outer retinal atrophy. Optical coherence tomography identified structural changes-intraretinal cysts in the early stages of disease, and later outer retinal atrophy. Genetic testing revealed that one rare allele (c.498_506del, p.(Ile167_Gly169del)) was present in all patients, with one patient being homozygous for the variant and six being heterozygous. In trans with this, one variant recurred twice (p.(Cys896Ter)), while the four remaining alleles were each observed once (p.(Pro1381Thr), p.(Ser478ProfsTer24), p.(Cys195Phe) and p.(Arg764Cys)). These findings show that the rare CRB1 variant, c.498_506del, is strongly associated with localised retinal dysfunction. The clinical findings are much milder than those observed with bi-allelic, loss-of-function variants in CRB1, suggesting this in-frame deletion acts as a hypomorphic allele. This is the most prevalent disease-causing CRB1 variant identified in the non-Asian population to date.

Utility of the serum C-reactive protein for detection of occult bacterial infection in children.

To assess the utility of serum C-reactive protein (CRP) as a screen for occult bacterial infection in children. Febrile children ages 3 to 36 months who visited an urban children's hospital emergency department and received a complete blood cell count and blood culture as part of their evaluation were prospectively enrolled from February 2, 2000, through May 30, 2001. Informed consent was obtained for the withdrawal of an additional 1-mL aliquot of blood for use in CRP evaluation. Logistic regression and receiver operator characteristic (ROC) curves were modeled for each predictor to identify optimal test values, and were compared using likelihood ratio tests. Two hundred fifty-six patients were included in the analysis, with a median age of 15.3 months (range, 3.1-35.2 months) and median temperature at triage 40.0 degrees C (range, 39.0 degrees C-41.3 degrees C). Twenty-nine (11.3%) cases of occult bacterial infection (OBI) were identified, including 17 cases of pneumonia, 9 cases of urinary tract infection, and 3 cases of bacteremia. The median white blood cell count in this data set was 12.9 x 10(3)/ micro L [corrected] (range, 3.6-39.1 x10(3)/ micro L) [corrected], the median absolute neutrophil count (ANC) was 7.12 x 10(3)/L [corrected] (range, 0.56-28.16 x10(3)/L) [corrected], and the median CRP level was 1.7 mg/dL (range, 0.2-43.3 mg/dL). The optimal cut-off point for CRP in this data set (4.4 mg/dL) achieved a sensitivity of 63% and a specificity of 81% for detection of OBI in this population. Comparing models using cut-off values from individual laboratory predictors (ANC, white blood cell count, and CRP) that maximized sensitivity and specificity revealed that a model using an ANC of 10.6 x10(3)/L [corrected] (sensitivity, 69%; specificity, 79%) was the best predictive model. Adding CRP to the model insignificantly increased sensitivity to 79%, while significantly decreasing specificity to 50%. Active monitoring of emergency department blood cultures drawn during the study period from children between 3 and 36 months of age showed an overall bacteremia rate of 1.1% during this period. An ANC cut-off point of 10.6 x10(3)/L [corrected] offers the best predictive model for detection of occult bacterial infection using a single test. The addition of CRP to ANC adds little diagnostic utility. Furthermore, the lowered incidence of occult bacteremia in our population supports a decrease in the use of diagnostic screening in this population.

This study evaluated the efficacy of a stepwise regimen of estradiol valerate for height control in girls with Marfan syndrome. Eight girls with Marfan syndrome who had completed estrogen treatment for height control were included. Estradiol valerate was started at a dose of 2 mg/day, and then was increased. The projected final height was estimated using the initial height percentile (on a disease-specific growth curve for Korean Marfan syndrome [gcPFHt]), and the initial bone age (baPFHt). After the estrogen treatment, the projected final height was compared to the actual final height (FHt). The median baseline chronological and bone age were 10.0 and 10.5 years, respectively. After a median of 36.5 months of treatment, the median FHt (172.6 cm) was shorter than the median gcPFHt (181.0 cm) and baPFHt (175.9 cm). In the six patients who started treatment before the age of 11 years, the median FHt (171.8 cm) was shorter than the median gcPFHt (181.5 cm) and baPFHt (177.4 cm) after treatment. The median differences between the FHt and gcPFHt and baPFHt were 9.2 and 8.3 cm, respectively. In two patients started treatment after the age of 11, the differences between FHt and gcPFHt, and baPFHt after treatment were -4 and 1.4 cm, and -1.2 and 0 cm for each case, respectively. A stepwise increasing regimen of estradiol valerate may be an effective treatment for height control in girls with Marfan syndrome, especially when started under 11 years old.

Universal varicella vaccination for 1-year-old children was introduced in Germany in 2004. We investigated changes in the incidence and type of varicella-associated neurologic complications in children during the first 7 years after universal vaccination recommendation. A surveillance study was conducted based on patients <17 years of age with an International Classification of Diseases (10th Revision) discharge diagnosis of varicella, annually reported by 22-29 pediatric hospitals in Bavaria, Germany, 2005 to 2011. Annual incidences were estimated and linear trend across years was assessed by Poisson regression models. Of a total of 1263 varicella-associated pediatric hospitalizations, 228 children (18.1%) had neurologic complications (median age 4 years, interquartile range 2-7; 56% male). The most frequent neurologic complications were febrile convulsion (32.0% of 228 children, median age 3.0 years), varicella encephalitis or meningitis (28.9%; median age 4.5 years), syncope (13.2%; median age 7.0 years) and cerebral convulsion (11.0%; median age 4.0 years). Other complications included ataxia (3.1%), facial nerve palsy (2.6%) and cerebral vasculitis/infarction (1.8%). Neurologic complications showed a continuous decrease between 2005 and 2011, from an incidence of 2.8 (95% confidence interval: 2.1-3.6) per 100,000 children <17 years of age to 1.2 (95% confidence interval: 0.7-2.1; P < 0.001). In particular, a marked decline was observed among children up to 7 years of age, mainly because of a decrease in the number of febrile convulsions and encephalitis or meningitis. The incidence of varicella-associated neurologic complications in children decreased approximately by 60% during the first 7 years following the recommendation for universal vaccination.

Adolescent refugees encounter traumatic stressors and are at risk of developing psychosocial health problems; limited research data exist internationally. This study aims to identify health risk behaviours among adolescent refugees resettling in Western Australia and assess the feasibility of using a standardised adolescent health questionnaire for this purpose. Refugees aged 12 years and above attending a tertiary Refugee Health Service (RHS) were recruited over 12 months. Sociodemographic data were collected. Psychosocial assessments based on the ' H ome, E ducation/Eating, A ctivities, D rugs, S exuality, S uicide/mental health' (HEADSS) framework were undertaken utilising interpreters where required. Health concerns identified were managed through the RHS. A total of 122 adolescents (20 ethnicities) participated; 65% required interpreters. Median age (range) was 14 (12-17) years. Most (80%) had nuclear family separation. Almost half (49%) had a deceased/missing family member. A third (37%) had lived in refugee camps and 20% had experienced closed detention. The median time (range) since arrival in Australia was 11 (2-86) months. Every adolescent had at least one health concern identified during the psychosocial assessment. Frequency of health concerns identified in each domain were 87% for home, 66% for education, 23% for eating, 93% for activities, 5% for drugs, 88% for sexuality and 61% for suicide/mental health. Most adolescents (75%) required intervention, consisting of counselling for health risk behaviours and/or referral to health or community services. It is feasible to use a standardised adolescent health questionnaire to identify health risk behaviours among a cohort of ethnically diverse adolescent refugees. Use of the questionnaire identified a large burden of psychosocial health issues requiring multidisciplinary intervention. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Juvenile idiopathic arthritis (JIA) is associated with significant morbidity in adulthood with at least one third of children continuing to have active inflammatory disease into their adult years and up to 60% of all patients continuing to have some limitation of their activities of daily living. A survey of service provision for these young people in the transition from paediatric to adult rheumatology care was therefore undertaken. A postal questionnaire was sent to all 92 members of the British Paediatric Rheumatology Group, representing 61 units providing a paediatric rheumatology service in the UK and Eire. Fifty-five replies were received representing a 60% completion rate of doctors and 84% of units on the mailing list. The majority of respondents were adult rheumatologists (n = 36, 65%) with 42% of respondents based in teaching hospitals. A median of 24 patients (new and follow-up, range 1-225) were seen in a median of two paediatric rheumatology clinics (range 0-15) per month. Eighteen per cent of units had a dedicated adolescent clinic (n = 9) with a median of one clinic per month and a median number of new patients per month of two (range 0-24) and 10 review patients (4-32). All the adolescent clinics involved an adult rheumatologist with five having a paediatrician in clinic and four having access to a paediatrician. The majority of clinics involved a specialist registrar (n = 6), a nurse specialist (n = 6), an occupational therapist (n = 6) and a physiotherapist (n = 5). The majority of clinics had flexible entry and exit criteria. In seven clinics there was a standardized process of transfer, first discussed at a median age of 13 yr (range 12-16) but no unit provided literature or organized pre-visits for this process. A demand for patient information resources (e.g. disease and drug information, careers) specifically aimed at adolescents with rheumatic diseases was identified. Generic health issues were only addressed by two clinics. Obstacles to current service provision and ideas for future developments were identified. This survey identifies a heterogeneity of provision of healthcare for adolescents with rheumatic disease and highlights the potential for further research and development.

To identify risk factors for the development of severe perineal lacerations and to give recommendations for their prevention in nulliparous women. A retrospective case-control analysis of deliveries at our University Hospital was performed. Multiparae, Caesarean sections, twin pregnancies, fetal breech position and preterm deliveries were excluded. Univariate and multivariate step forward regression analyses were performed; correlations between contributors were further analyzed by Spearman Rank Correlation. Differences between the degree of lacerations and maternal age were further analyzed with Friedman ANOVA followed by Dunn's Multiple Comparison Test. A total of 2,967 deliveries fitted our inclusion criteria, 50 (1.7%) mothers had higher-grade lacerations. Mediolateral and median episiotomy, advanced maternal age, vaginal operative delivery, higher fetal birth weight and abnormal cephalic presentation were associated with severe lacerations. Advanced maternal age plays an important role in the development of anal sphincter tears in nulliparous women. Episiotomy and operative vaginal deliveries should be restrictively performed when possible. To identify further preventive approaches in patients with accumulated risk factors prospective randomized studies are needed.

To report a possible association between human papilloma virus (HPV) vaccination and uveitis. Spontaneous reports from the National Registry of Drug-Induced Ocular Side effects, World Health Organization and Food and Drug Administration were collected on uveitis associated with human papilloma virus vaccination. A MEDLINE search was performed using keywords "uveitis," "iritis," "iridocyclitis," "human papilloma virus," "Cervarix", and "Gardasil." Data garnered from spontaneous reports included the age, gender, adverse drug reaction (ADR), date of administration, concomitant administration of other vaccinations, time until onset of ADR, other systemic reactions, and dechallenge and rechallenge data. A total of 24 case reports of uveitis associated with human papilloma virus vaccination were identified, all cases were female, and the median age was 17. Median time from HPV vaccination to reported ADR was 30 days (range 0-476 days). According to World Health Organization criteria, the relationship between human papilloma virus vaccination and uveitis is "possible." Causality assessments are based on the time relationship of drug administration, uveitis development and re-challenge data. Clinicians should be aware of a possible bilateral uveitis and papillitis following HPV vaccination.

Manifestations of Duchenne and Becker muscular dystrophy (DBMD) are present in up to 40% of heterozygous females, but there are few reports of females who exhibit skeletal muscle symptoms in childhood. From the Muscular Dystrophy Surveillance Tracking and Research Network, a multi-site population-based surveillance network for dystrophinopathy, nine symptomatic female heterozygotes with onset of symptoms prior to age 9 years were identified. The median age at diagnosis was 8.3 years, and the median interval from first symptoms to diagnosis was 1.35 years. Of the nine female heterozygotes, four had a positive family history, seven had intellectual disability and five had at least one mental health disorder. Mental health concerns included attention deficit hyperactivity disorder (ADHD), autism spectrum features, bipolar disorder, and depression. The frequency of intellectual and mental health problems in this group is higher than previously reported for affected males and for symptomatic females. These findings may have implications for diagnosis of early manifesting heterozygotes and for their health supervision. © 2014 Wiley Periodicals, Inc.

To analyze patients with a confirmed voice disorder in order to identify patterns regarding age, gender, and occupation compared to the general public. To explore effects of voice therapy according to the Voice Handicap Index (VHI) score pre- and post-therapy in relation to the number of sessions, age, and gender. Prospective cohort study. This study was conducted as a collaborative project between Linköping University and hospitals in the south-east health care region in Sweden. Six voice clinics participated by asking their patients voluntarily to complete the Swedish version of the VHI at the beginning and end of therapy. The two most prevalent diagnoses were dysphonia (43%) and phonasthenia (25%). Among the working population, the three most common occupational fields were education, health care, and child-care. The majority of the patients were women (74.3%), and the mean age of all patients was 55 years. A significant improvement in VHI scores was found after therapy, with an average decrease of 19 median points in total score and a substantial effect size (0.55). The number of sessions did not significantly correlate with the mean VHI score difference but had a weak correlation to the start and end scores. Increasing age correlated with a higher median VHI score both at the start and end of therapy but did not affect the average decrease between the two measurements.

To investigate obesity as susceptibility factor in patients with idiopathic AA amyloidosis. Clinical, biochemical and genetic data were obtained from 146 patients with AA amyloidosis. Control groups comprised 40 patients with long-standing inflammatory diseases without AA amyloidosis and 56 controls without any inflammatory disease. Patients with AA amyloidosis had either familial Mediterranean fever (FMF) or long-standing rheumatic diseases as underlying inflammatory disease (n = 111, median age 46 years). However, in a significant proportion of patients with AA amyloidosis no primary disease was identified (idiopathic AA; n = 37, median age 60 years). Patients with idiopathic AA amyloidosis were more obese and older than patients with AA amyloidosis secondary to FMF or rheumatic diseases. Serum leptin levels correlated with the body mass index (BMI) in all types of AA amyloidosis. Elevated leptin levels of more than 30 µg/l were detected in 18% of FMF/rheumatic + AA amyloidosis and in 40% of patients with idiopathic AA amyloidosis (p = .018). Finally, the SAA1 polymorphism was confirmed as a susceptibility factor for AA amyloidosis irrespective of the type of the disease. Obesity, age and the SAA1 polymorphism are susceptibility factors for idiopathic AA amyloidosis. Recent advances in treatment of FMF and rheumatic disorders will decrease the incidence of AA amyloidosis due to these diseases. Idiopathic AA, however, might be an emerging problem in the ageing and increasingly obese population.

The aims of the study were in a large group of neonates to identify the relative effect of bodyweight, postnatal age, and gestational age on zidovudine (ZDV) pharmacokinetics; to link concentrations with lactate and hemoglobin levels; and to find the more appropriate neonatal ZDV dose. In 484 neonates aged 3-30 days, born to HIV-infected mothers, 767 ZDV and 417 ZDV glucuronide concentrations were collected. Using a population approach, ZDV clearance per kilogram increased with postnatal age but not with gestational age. High neonatal exposures were found as follows: 14,025 ng/mL·h the first week and 6528 ng/mL·h the second week in comparison to 3000 ng/mL·h in adults. At month 1, median lactate level was 2.8 mmol/L (60%, ≥2.5 mmol/L) and median hemoglobin was 10.1 g/dL (90%, <12 g/dL). ZDV trough concentrations at first sampling (days 3-7) or at last sampling (day 20 ± 10) were significantly negatively correlated to hemoglobin at months 1, 3, and 6 (P < 0.02). ZDV maximal or trough concentrations at days 3-7 and at day 20 ± 10 were significantly positively correlated to lactate levels at months 3 and 6, respectively. To obtain an exposure comparable to adults, which should reduce neonatal toxicity, doses should to be decreased during the first 2 weeks of life.

Background: We sought to clarify possibly modifiable risk factors related to pollution responsible for acute bronchiolitis in hospitalized infants. Methods: For this observational study, we recruited 213 consecutive infants with bronchiolitis (cases: median age: 2 months; age range: 0.5–12 months; boys: 55.4%) and 213 children aged <3 years (controls: median age: 12 months; age range: 0.5–36 months; boys: 54.5%) with a negative medical history for lower respiratory tract diseases hospitalized at ‘Sapienza’ University Rome and IRCCS Bambino Gesù Hospital. Infants’ parents completed a standardized 53-item questionnaire seeking information on social-demographic and clinical characteristics, indoor pollution, eating habits and outdoor air pollution. Multivariate logistic regression analyses were run to assess the independent effect of risk factors, accounting for confounders and effect modifiers. Results: In the 213 hospitalized infants the questionnaire identified the following risk factors for acute bronchiolitis: breastfeeding ⩾3 months (OR: 2.1, 95% confidence interval [CI]: 1.2–3.6), presence of older siblings (OR: 2.8, 95% CI: 1.7–4.7), ⩾4 cohabitants (OR: 1.5, 95% CI: 1.1–2.1), and using seed oil for cooking (OR: 1.7, 95% CI: 1.2–2.6). Having renovated their home in the past 12 months and concurrently being exposed daily to smoking, involving more than 11 cigarettes and two or more smoking cohabitants, were more frequent factors in cases than in controls (p = 0.021 and 0.05), whereas self-estimated proximity to road and traffic was similar in the two groups. Conclusions: We identified several risk factors for acute bronchiolitis related to indoor and outdoor pollution, including inhaling cooking oil fumes. Having this information would help public health authorities draw up effective preventive measures – for example, teach mothers to avoid handling their child when they have a cold and eliminate exposure to second-hand tobacco smoke.

To determine if endophthalmitis following cataract surgery is linked to increased mortality. Increased mortality has been linked to patients with cataract and cataract surgery. We tested the hypothesis that post-cataract endophthalmitis has a greater risk of death than pseudophakes who do not develop this complication. Case-control study conducted in a tertiary public hospital. The study group comprised 50 consecutive patients with post-cataract endophthalmitis, and these were matched with selected controls. Patients with endophthalmitis following cataract surgery were identified from a prospective electronic surgical database. Subsequently, it was determined if the patient was deceased at the time of sequestration (September 2015), and the date of death was recorded. A previously described population who had undergone cataract surgery in the same facility was selected as a control group, and the population was case-matched in terms age, gender, presence or absence of diabetes and/or hypertension. The median survival rates were determined for the control group and the patients with post-cataract endophthalmitis. Fifty patients were identified as undergoing endophthalmitis post-cataract surgery, and 48 (n = 48) met inclusion criteria (mean age 72 years ±12 SD with 30:18 F:M); 17% were diabetic, and 50% had systemic hypertension. No statistically significant difference in median survival between the study and control cases was identified (100 months (95% confidence interval 86-114) vs. 106 months (95% confidence interval 66-146), respectively, P = 0.756). Post-cataract endophthalmitis was not associated with an increased rate of mortality in this study. © 2018 Royal Australian and New Zealand College of Ophthalmologists.

Tissue accumulation of advanced glycation end-products (AGE) is thought to be a contributing factor to the progression of cardiovascular disease (CVD). Skin autofluorescence, a non-invasive measure of AGE accumulation using autofluorescence of the skin under ultraviolet light, has shown associations with CVD in haemodialysis patients. The present study aimed to evaluate relationships of skin autofluorescence to renal function as well as CVD in pre-dialysis patients with chronic kidney disease (CKD). Subjects in this cross-sectional analysis comprised 304 pre-dialysis CKD patients [median age, 62.0 years; median estimated glomerular filtration rate (eGFR), 54.3 mL/min/1.73 m(2); diabetes, n = 81 (26.6%)]. AGE accumulation in skin was assessed by skin autofluorescence using an autofluorescence reader. Relationships between skin autofluorescence, eGFR, CVD history and other parameters were evaluated. Skin autofluorescence correlated negatively with eGFR (r = -0.42, P < 0.01) and increased as CKD stage advanced. Multiple regression analysis revealed significant correlations of skin autofluorescence with age, presence of diabetes, eGFR and CVD history in CKD patients (R(2) = 30%). Age, male gender, smoking history, skin autofluorescence and eGFR were significantly correlated with CVD history, and multiple logistic regression analysis identified age [odds ratio (OR), 1.09; 95% confidence interval (CI), 1.03-1.15; P < 0.01], history of smoking (OR, 6.50; 95%CI, 1.94-21.83; P < 0.01) and skin autofluorescence (OR, 3.74; 95%CI, 1.54-9.24; P < 0.01) as independent factors. Tissue AGE accumulation measured as skin autofluorescence increased as GFR decreased and was related to CVD history in CKD patients. Non-invasive autofluorescence readers may provide potential markers for clinical risk assessment in pre-dialysis CKD patients.

The optimal approach to estrogen replacement in girls with Turner syndrome has not been determined. The aim of the study was to assess the effects of an individualized regimen of low-dose ethinyl estradiol (EE2) during childhood from as early as age 5, followed by a pubertal induction regimen starting after age 12 and escalating to full replacement over 4 years. This study was a prospective, randomized, double-blind, placebo-controlled clinical trial. The study was conducted at two US pediatric endocrine centers. Girls with Turner syndrome (n = 149), aged 5.0-12.5 years, were enrolled; data from 123 girls were analyzable for pubertal onset. Interventions comprised placebo or recombinant GH injections three times a week, with daily oral placebo or oral EE2 during childhood (25 ng/kg/d, ages 5-8 y; 50 ng/kg/d, ages >8-12 y); after age 12, all patients received escalating EE2 starting at a nominal dosage of 100 ng/kg/d. Placebo/EE2 dosages were reduced by 50% for breast development before age 12 years, vaginal bleeding before age 14 years, or undue advance in bone age. The main outcome measures for this report were median ages at Tanner breast stage ≥2, median age at menarche, and tempo of puberty (Tanner 2 to menarche). Patterns of gonadotropin secretion and impact of childhood EE2 on gonadotropins also were assessed. Compared with recipients of oral placebo (n = 62), girls who received childhood low-dose EE2 (n = 61) had significantly earlier thelarche (median, 11.6 vs 12.6 y, P < 0.001) and slower tempo of puberty (median, 3.3 vs 2.2 y, P = 0.003); both groups had delayed menarche (median, 15.0 y). Among childhood placebo recipients, girls who had spontaneous breast development before estrogen exposure had significantly lower median FSH values than girls who did not. In addition to previously reported effects on cognitive measures and GH-mediated height gain, childhood estrogen replacement significantly normalized the onset and tempo of puberty. Childhood low-dose estrogen replacement should be considered for girls with Turner syndrome.

The primary goal of this study was to describe epidemiology and management strategies of the perforated duodenal ulcer, as well as the most common methods of laparoscopic perforated duodenal ulcer repair. The secondary goal was to demonstrate the value of prospective and retrospective studies regarding the early results of surgery and the risk factors. The tertiary goal was to emphasize the benefits of this operation, and the fourth goal was to clarify the possible risk factors associated with laparoscopic repair of the duodenal ulcer. The Medline/Pubmed database was used. Review was done after evaluation of 96 retrieved full-text articles. Thirteen prospective and twelve retrospective studies were selected, grouped, and summarized. The spectrum of the retrospective studies' results are as follows: median overall morbidity rate 10.5 %, median conversion rate 7%, median hospital stay 7 days, and median postoperative mortality rate 0%. The following is the spectrum of results of the prospective studies: median overall morbidity rate was slightly less (6%); the median conversion rate was higher (15%); the median hospital stay was shorter (5 days) and the postoperative mortality was higher (3%). The risk factors identified were the same. Shock, delayed presentation (> 24 hours), confounding medical condition, age > 70 years, poor laparoscopic expertise, ASA III-IV, and Boey score should be considered preoperative laparoscopic repair risk factors. Each of these factors independently should qualify as a criterion for open repair due to higher intraoperative risks as well as postoperative morbidity. Inadequate ulcer localization, large perforation size (defined by some as > 6 mm diameter, and by others as > 10 mm), and ulcers with friable edges are also considered as conversion risk factors.

Can the height of fall predict long bone fracture in children under 24 months?

PubMed

Hansoti, Bhakti; Beattie, Tom

It can be difficult to determine the exact mechanism of injury in infants and babies aged 24 months and under. Falls are the most common mechanism of injury in children. The purpose of this study is to identify the relationship between reported height of fall and long bone fracture. All children aged under 24 months who sustained a fracture (in the year 2003) were identified prospectively on the departmental fracture database. These children were matched for age and sex with children identified as having fallen but not having sustained a fracture. Sixty-three children aged 24 months and under were studied. The median height of fall in this group was 48 cm and that in the control group was 20 cm, P<0.001. A significant correlation was observed between the height of fall (cm) and severity of injury (Pearson's correlation coefficient=0.255). Receiver operating characteristic analysis indicates that the likelihood of significant fracture requiring admission and/or manipulation under anaesthesia occurs with a fall from a height of 56 cm [sensitivity 80% (confidence interval 29-97%), specificity 79% (confidence interval 70-86%)]. It was not possible to identify a height at which the risk of any fracture injury became significantly more likely. Height of fall is only one factor that must be considered in dealing with fracture injury in children aged 24 months or under. However, significant injury presenting with falls from less than 50 cm should be critically evaluated.

To introduce systems biology as a conceptual framework for research in family medicine, based on empirical data from a case study on the prediction of influenza vaccination outcomes. This concept is primarily oriented towards planning preventive interventions and includes systematic data recording, a multi-step research protocol and predictive modelling. Factors known to affect responses to influenza vaccination include older age, past exposure to influenza viruses, and chronic diseases; however, constructing useful prediction models remains a challenge, because of the need to identify health parameters that are appropriate for general use in modelling patients' responses. The sample consisted of 93 patients aged 50-89 years (median 69), with multiple medical conditions, who were vaccinated against influenza. Literature searches identified potentially predictive health-related parameters, including age, gender, diagnoses of the main chronic ageing diseases, anthropometric measures, and haematological and biochemical tests. By applying data mining algorithms, patterns were identified in the data set. Candidate health parameters, selected in this way, were then combined with information on past influenza virus exposure to build the prediction model using logistic regression. A highly significant prediction model was obtained, indicating that by using a systems biology approach it is possible to answer unresolved complex medical uncertainties. Adopting this systems biology approach can be expected to be useful in identifying the most appropriate target groups for other preventive programmes.

A longitudinal, prospective, observational, single-center, cohort study on healthy donors (HDs) was designed to identify predictors of CD34 + cells on day 5 with emphasis on the predictive value of the basal CD34 + cell count. As potential predictors of mobilization, age, sex, body weight, height, blood volume as well as white blood cell count, peripheral blood (PB) mononuclear cells, platelet count, hematocrit, and hemoglobin levels were considered. Two different evaluations of CD34 + cell counts were determined for each donor: baseline (before granulocyte colony-stimulating factor [G-CSF] administration) and in PB after G-CSF administration on the morning of the fifth day (day 5). A total of 128 consecutive HDs (66 males) with a median age of 43 years were enrolled. CD34 + levels on day 5 displayed a non-normal distribution, with a median value of 75.5 cells/µL. To account for the non-normal distribution of the dependent variable, a quantile regression analysis to predict CD34 + on day 5 using the baseline value of CD34 + as the key predictor was performed. On crude analysis, a baseline value of CD34 + ranging from .5 cells/µL to 1 cells/µL predicts a median value of 50 cells/µL on day 5; a value of 2 cells/µL predicts a median value of 70.7 cells/µL; a value of 3 cells/µL to 4 cells/µL predicts a median value of 91.3 cells/µL, and a value ≥ 5 predicts a median value of 112 cells/µL. In conclusion, the baseline PB CD34 + cell count correlates with the effectiveness of allogeneic PB stem cell mobilization and could be useful to plan the collection.

This paper describes the outcomes of gastrostomy feeding in patients with Crohn's disease (CD). Patients with CD who attended the Royal Hospital for Children, Glasgow and received gastrostomy feeding for at least two years between 2003 and 2010 were identified from the clinical database. The data recorded included the anthropometric data, CD phenotype, the surgical technique that was used, complications, medication, feed type, median feed, calories, volume and clinical outcomes. The study identified 16 patients (14 male) who had a gastrostomy inserted using a pull technique at a median age of 12.6 years. Of these two required laparoscopic placement. Short-term complications lasting less than one month were experienced by nine (56%) patients and one (6%) experienced long-term complications. Anthropometry significantly improved at follow-up compared to baseline: at 12 months, the body mass index z-score was 1.11 (p = 0.005) and the weight z-score was 0.19 (p < 0.05). At 24 months, the height z-score was -1.03 (p = 0.04). The daily median volume and calories from feeds increased significantly from baseline to post-PEG insertion, from 400 to 738 mL and 705 to 860 kcal/day (p ≤ 0.01). Gastrostomy feeding for paediatric patients with CD was associated with improved nutrition, weight gain and growth outcomes. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

AbstractFlea-borne (murine) typhus is a global rickettsiosis caused by Rickettsia typhi . Although flea-borne typhus is no longer nationally notifiable, cases are reported for surveillance purposes in a few U.S. states. The infection is typically self-limiting, but may be severe or life-threatening in some patients. We performed a retrospective review of confirmed or probable cases of fatal flea-borne typhus reported to the Texas Department of State Health Services during 1985-2015. When available, medical charts were also examined. Eleven cases of fatal flea-borne typhus were identified. The median patient age was 62 years (range, 36-84 years) and 8 (73%) were male. Patients presented most commonly with fever (100%), nausea and vomiting (55%), and rash (55%). Respiratory (55%) and neurologic (45%) manifestations were also identified frequently. Laboratory abnormalities included thrombocytopenia (82%) and elevated hepatic transaminases (63%). Flea or animal contact before illness onset was frequently reported (55%). The median time from hospitalization to administration of a tetracycline-class drug was 4 days (range, 0-5 days). The median time from symptom onset to death was 14 days (range, 1-34 days). Flea-borne typhus can be a life-threatening disease if not treated in a timely manner with appropriate tetracycline-class antibiotics. Flea-borne typhus should be considered in febrile patients with animal or flea exposure and respiratory or neurologic symptoms of unknown etiology.

Background Most patients with malignant peritoneal mesothelioma (MPM) present with late-stage, unresectable disease that responds poorly to systemic chemotherapy while, at the same time, effective targeted therapies are lacking. We assessed the efficacy of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemoperfusion (HIPEC) in MPM. Methods We prospectively analyzed 65 patients with MPM undergoing CRS/HIPEC between 2001 and 2010. Kaplan–Meier survival curves and multivariate Cox-regression models identified prognostic factors affecting oncologic outcomes. Results Adequate CRS was achieved in 56 patients (CC-0 = 35; CC-1 = 21), and median simplified peritoneal cancer index (SPCI) was 12. Pathologic assessment revealed predominantly epithelioid histology (81 %) and biphasic histology (8 %), while lymph node involvement was uncommon (8 %). Major postoperative morbidity (grade III/IV) occurred in 23 patients (35 %), and 60-day mortality rate was 6 %. With median follow-up of 37 months, median overall survival was 46.2 months, with 1-, 2-, and 5-year overall survival probability of 77, 57, and 39 %, respectively. Median progression-free survival was 13.9 months, with 1-, 2-, and 5-year disease failure probability of 47, 68, and 83 %, respectively. In a multivariate Cox-regression model, age at surgery, SPCI >15, incomplete cytoreduction (CC-2/3), aggressive histology (epithelioid, biphasic), and postoperative sepsis were joint significant predictors of poor survival (chi square = 42.8; p = 0.00001), while age at surgery, SPCI >15, incomplete cytoreduction (CC-2/3), and aggressive histology (epithelioid, biphasic) were joint significant predictors of disease progression (Chi square = 30.6; p = 0.00001). Conclusions Tumor histology, disease burden, and the ability to achieve adequate surgical cytoreduction are essential prognostic factors in MPM patients undergoing CRS/HIPEC. PMID:24322529

Background Both insufficient and excess iodine may produce thyroid disease. After salt iodization in China, the median urine iodine concentration (UIC) of children aged 8–10 years appeared adequate. However, it is unknown whether dietary changes due to rapid economic development in Shanghai have affected whole population iodine nutrition. Objective To assess dietary iodine intake, UIC and the prevalence of thyroid disease in the general population of Shanghai. Design A cross-sectional survey was conducted with general participants aged 5–69 years (n = 7,904) plus pregnant and lactating women (n = 380 each) selected by stratified multistage sampling. The iodine concentrations in their salt, drinking water and urine were measured. Daily iodine intake was estimated using the total diet study approach. Serum thyroid hormone concentrations and thyroid-related antibodies were measured and thyroid ultrasonography was performed. Results The median iodine concentration in salt was 29.5 mg/kg, and 12.8 µg/L in drinking water. Iodized salt, used by 95.3% of participants, contributed 63.5% of total dietary iodine. Estimated daily iodine intake was 225.96 µg. The median UIC of general participants was 146.7 µg/L; UIC <100 µg/L (iodine insufficiency) was seen in 28.6%; UIC >300 µg/L (iodine excess) in 10.1%. Pregnant women had a median UIC of 135.9 µg/L, with UIC <150 µg/L in 55.4%. Thyroid nodules and subclinical hypothyroidism were found in 27.44% and 9.17%, respectively. Conclusions According to published criteria, the current dietary iodine intake in Shanghai was generally sufficient and safe, but insufficient in pregnant women. Thyroid nodules and subclinical hypothyroidism were the commonest thyroid diseases identified. PMID:22911705

To describe our experience and current management approach for congenital nasal neuroglial heterotopia (NGH) and encephaloceles. Retrospective chart review at a tertiary pediatric hospital from 1970 to 2013. Thirty patients met inclusion criteria: 21 NGH and nine encephaloceles. Data including demographics, pathology, imaging modality, surgical approach, resection extent, outcomes, and complications were analyzed. Fourteen NGH patients (67%) presented with an internal nasal mass and nasal obstruction. Three patients (14%) presented with an external nasal mass and four (19%) had a mixed lesion. Median age at surgery was 0.51 years (interquartile range 1.32 years). Thirteen (62%) had an intranasal endoscopic approach. Median operative time was 1.6 hours (interquartile range 1.2 hours), and there were no major complications. Nine patients with encephalocele were identified: six (67%) presented with transethmoidal encephaloceles, two (22%) presented with nasoethmoidal encephaloceles, and one (11%) presented with a nasofrontal lesion. The median age at surgery was 1.25 years (interquartile range 1.4 years). All patients required a craniotomy for intracranial extension. Median operative time was 5 hours (interquartile range 1.9 hours), and eight patients (88%) had a total resection. Length of stay ranged from 3 to 14 days. Nasal neuroglial heterotopia and encephaloceles are very rare lesions that require multidisciplinary evaluation and management. At our institution, there has been a shift to magnetic resonance imaging alone for the evaluation of NGH to avoid radiation exposure. Endoscopic extracranial resection is feasible for most intranasal and mixed NGH without an increase in operative time, residual disease, or complications. 4.

AIM: To determine whether Helicobacter pylori (H. pylori) infection confers a higher risk of Nonalcoholic fatty liver disease (NAFLD). METHODS: Healthy people who underwent health screening were analyzed retrospectively. Inclusion criteria were age ≥ 20 years, history of H. pylori infection, and recorded insulin level. Participants were classified as H. pylori positive or negative according to 13C urea breath tests. NAFLD was defined using the hepatic steatosis index (HSI) and NAFLD liver fat score (NAFLD-LFS). Those with an HSI > 36 or NAFLD-LFS > -0.640 were considered to have NAFLD. Multivariable logistic regression was performed to identify risk factors for NAFLD. RESULTS: Three thousand six hundred and sixty-three people were analyzed and 1636 (44.7%) were H. pylori positive. H. pylori infection was associated with older age, male gender, hypertension, higher body mass index, and a dyslipidemic profile. HSI differed significantly between H. pylori positive and negative subjects (median 33.2, interquartile range (IQR) 30.0-36.2 for H. pylori-positive vs median 32.6, IQR 29.8-36.0 for negative participants, P = 0.005), but NAFLD-LSF did not [median -1.7, IQR -2.4 - -0.7 vs median -1.8, IQR -2.4-(-0.7), respectively, P = 0.122]. The percentage of people with NAFLD did not differ between infected and uninfected groups: HIS, 26.9% vs 27.1%, P = 0.173; NAFLD-LFS, 23.5% vs 23.1%, P = 0.778. H. pylori infection was not a risk factor, but C-reactive protein concentration and smoking were significant risk factors for NAFLD. CONCLUSION: H. pylori infection is not a risk factor for NAFLD as indicated by HSI or NAFLD-LFS. Prospective, large-scale studies involving liver biopsies should be considered. PMID:26937147

The craniopharyngeal canal is a rare, well-corticated defect through the midline of the sphenoid bone from the sellar floor to the anterosuperior nasopharyngeal roof. We reviewed a series of craniopharyngeal canals to determine a system of classification that might better our understanding of this entity, highlight the range of associated pathologic conditions, and optimize patient treatment. Available MR imaging, CT, and clinical data (from 1989-2013) of 29 patients (10 female, 15 male, 4 unknown; median age, 4 years; age range, 1 day-65 years) with craniopharyngeal canals were retrospectively examined. Qualitative assessment included orthotopic or ectopic adenohypophysis and the presence of a tumor and/or cephalocele. The midpoint anteroposterior diameter was measured. Clinical and imaging data were evaluated for pituitary dysfunction and accompanying anomalies. Craniopharyngeal canals were qualitatively separated into 3 types: incidental canals (type 1); canals with ectopic adenohypophysis (type 2); and canals containing cephaloceles (type 3A), tumors (type 3B), or both (type 3C), including pituitary adenoma, craniopharyngioma, dermoid, teratoma, and glioma. Quantitative evaluation showed a significant difference (P < .0001) in the anteroposterior diameters of type 1 canals (median, 0.8; range, 0.7-1.1 mm), type 2 canals (median, 3.9, range, 3.5-4.4 mm), and type 3 canals (median, 9.0; range, 5.9-31.0 mm) imparting small, medium, and large descriptors. Canals with cephaloceles all contained an ectopic adenohypophysis. The craniopharyngeal canals were associated with pituitary dysfunction (6/29) and congenital anomalies (8/29). Accurate diagnosis and classification of craniopharyngeal canals are valuable to characterize lesions requiring surgery, identify patients with potential pituitary dysfunction, and avoid iatrogenic hypopituitarism or CSF leak during surgical resection of nasopharyngeal masses.

Management of Paediatric Testicular Torsion - Are we adhering to Royal College of Surgeons (RCS) recommendations.

Thakkar, H S; Yardley, I; Kufeji, D

2018-05-01

Introduction In 2015, the Royal College of Surgeons of England (RCS) commissioned the East Midlands Clinical Network to develop a set of guidelines for the management of paediatric torsion. Two quality measures identified were the provision of surgery locally where possible and 100% of explorations within three hours. We sought to assess the adherence to these quality measures within our referral network. Materials and methods Retrospective data were collected for all paediatric scrotal explorations performed within our centre between January 2014 and July 2016. Patient demographics, sources of referral, transfer times, time to surgery and operative findings were obtained. Results A total of 100 patients underwent a scrotal exploration. Median age at presentation was 11 years (range 4 months to 15 years). Fifty-three per cent of referrals were from network hospitals. The median duration of symptoms was 25 hours (range 1-210 hours). The median transfer time from local centres was 120 minutes (range 45-540 minutes). The median time to theatre from the decision being made to operate was 60 minutes (range 30-600 minutes). Eighty-seven per cent of cases were explored within three hours. There were 13 cases of torsion with one orchidectomy. When taking into account the transfer time for external patients aged over five years without precluding comorbidities, exploration within three hours dropped to 18 of 46 (39%). Conclusion The RCS guidelines recognise the need for specialist input in very young patients. A large proportion of explorations are, however, currently taking place in older patients with unacceptably long transfer times. We propose an extension of this review nationally to work towards the local provision of care for suitable patients.

The influence of donor cause of death (DCD) on survival after lung transplantation (LTx) is uncertain. This was investigated using data from a national prospective cohort study of adult single and bilateral LTx undertaken between July 1995 and June 2002. DCD was categorized a priori into vascular and tumor (V), traumatic (T), hypoxic brain damage (H) and infective (I) causes. All T donor deaths were the result of blunt trauma. Risk factors for early (30 days), late (30 days to 5 years) and overall (5 years) mortality were identified using Cox regression analysis. Of 580 eligible transplants, DCDs were classified as V (n = 372), T (n = 153), H (n = 38) and I (n = 17). V donors were older (median 42 years) than the others (medians < 27 years) (p < 0.001). T donors were more likely to be of male gender (p < 0.001). Two hundred fifty-nine patients died within 5 years of surgery. The median follow-up time of survivors was 37 months. Unadjusted 5-year Kaplan-Meier survival rates did not vary with DCD (p = 0.6). Cox analysis identified donor age group, recipient diagnosis, pre-operative recipient ventilation, donor-recipient size mismatch, donor-recipient blood group variance, cytomegalovirus (CMV) mismatch and recipient creatinine clearance as predictors of mortality. After adjustment for these risk factors, DCD was not identified as a predictor of early (p = 0.2), late (p = 0.5) or overall mortality (p = 0.4) in LTx recipients. We found that DCD did not affect mid-term survival after LTx.

The aim of this study was to evaluate the efficacy of vacuum-assisted closure therapy in patients with open abdomen due to secondary peritonitis and to identify possible risk factors of fistula formation. The hospital OPS-database (time period 2005-2014) was searched to identify patients treated with an open abdomen due to secondary peritonitis, who underwent vacuum-assisted closure therapy. Medical records were retrospectively analyzed for patients' characteristics, cause of peritonitis, duration of vacuum therapy, number of relaparotomies, fascial closure rates, and risk factors of fistula formation. Forty-three patients (19 male, 24 female) with a median age of 65 years (range 24-90 years) were identified. The major cause of secondary peritonitis was anastomotic leakage after intestinal anastomosis or bowel perforation, the median APACHE II score was 11. Median duration of VAC treatment was 12 days (range 3-88 days). Twenty of 43 (47 %) patients died from septic complications. Delayed fascial closure was obtained by suturing in 20 of 43 patients (47 %). Overall 16 of 43 (37 %) patients developed enteroatmospheric fistulas. Re-explorations after starting VAC treatment and duration of VAC therapy were significantly associated with the occurrence of enteroatmospheric fistulas (p < 0.001). ROC curve analysis determined the optimal duration of VAC therapy to reduce the risk of fistula formation at 13 days. Long-term VAC treatment of patients with an open abdomen due to secondary peritonitis results in a relatively low fascial closure rate and a high risk of fistula formation.

Pneumocystis jirovecii pneumonia occurs in various immunocompromised patients. Despite the prophylaxis strategies in clinical practice, certain patients develop P. jirovecii pneumonia. This study was performed to investigate pediatric cases with P. jirovecii pneumonia in a single center. We identified pediatric patients younger than 19 years with microbiologically confirmed P. jirovecii pneumonia from January 2000 to February 2014. A retrospective chart review was performed. Fifteen episodes of P. jirovecii pneumonia in 14 patients were identified with median age of 8.3 years (range, 0.4-18.6 years). Among these patients, 11 patients had hematology-oncology diseases, 2 had primary immunodeficiency disorders (one with severe combined immunodeficiency and the other with Wiskott Aldrich syndrome), 1 had systemic lupus erythematosus and 1 received kidney transplant. Four patients were transplant recipients; 1 allogeneic and 2 autologous hematopoietic cell transplant and 1 with kidney transplant. The median absolute lymphocyte count at the diagnosis of P. jirovecii pneumonia was 5,156 cells/mm(3) (range, 20-5,111 cells/mm(3)). In 13 episodes (13 of 15, 86.7%), patients were not receiving prophylaxis at the onset of P. jirovecii pneumonia. For treatment, trimethoprim/sulfamethoxazole was given as a main therapeutic agent in all 15 episodes. Steroid was given in 9 episodes (60%). Median treatment duration was 15 days (range, 4-33 days). Overall mortality at 60 days was 35.7% (5 of 14). Majority of our patients developed P. jirovecii pneumonia while not on prophylaxis. Continuous efforts and more data are needed to identify high risk patients who may get benefit from P. jirovecii pneumonia prophylaxis.

Cardiovascular risk factors in people on antiretroviral treatment (ART) are poorly documented in resource-constrained settings. A cross-sectional study was conducted in 2009 to assess prevalence of diabetes and hypertension in a sample of 242 HIV-infected patients who had initiated ART between 1998 and 2002 in Dakar, Senegal (ANRS 1215 observational cohort). World Health Organization (WHO) criteria were applied to diagnose diabetes and hypertension. Multiple logistic regressions were used to identify factors associated with diabetes and hypertension. Patients had a median age of 46 years and had received ART for a median duration of about 9 years. 14.5% had diabetes and 28.1% had hypertension. Long duration of ART (≥119 months), older age, higher body mass index (BMI), and higher levels of total cholesterol were associated with higher risks of diabetes. Older age, higher BMI at ART initiation, and higher levels of triglycerides were associated with higher risk of hypertension. This study shows that diabetes and hypertension were frequent in these Senegalese HIV patients on ART. It confirms the association between duration of ART and diabetes and highlights the need to implement programs for prevention of cardiovascular risk factors in HIV patients from resource-constrained settings.

Cocaine use is prevalent among HIV-infected individuals. While cross-sectional studies suggest that cocaine users may be at increased risk for depression, long-term effects of cocaine on depressive symptoms remain unclear. This is a longitudinal study of 341 HIV-infected and uninfected men (135 cocaine users and 206 controls) ages 30-60 enrolled in the Multicenter AIDS Cohort Study during 1996-2009. The median baseline age was 41; 73% were African-American. In mixed-effects models over a median of 4.8 years of observation, cocaine use was associated with higher depressive symptoms independent of age, education level, and smoking (n = 288; p = 0.02); HIV infection modified this association (p = 0.03). Latent class mixed models were used to empirically identify distinct depressive trajectories (n = 160). In adjusted models, cocaine use was associated with threefold increased odds of membership in the class with persistent high depressive symptoms (95% confidence interval (CI) 1.38-6.69) and eightfold increased odds (95% CI (2.73-25.83) when tested among HIV-infected subjects only. Cocaine use is a risk factor for chronic depressive symptoms, particularly among HIV-infected men, highlighting the importance of integrating mental health and substance use treatments to address barriers to well-being and successful HIV-care.

To evaluate the feasibility of semen cryopreservation in pubertal boys before they receive gonadotoxic therapy and to identify which pretreatment parameters might predict successful cryopreservation. Retrospective data analysis. Tertiary fertility center, academic children's hospital. Between 1995 and 2005, 80 boys (median age 16.6 years, range 13.7-18.9 years) consulted the outpatient clinic of andrology for semen cryopreservation before a potentially gonadotoxic treatment. We assessed the pretreatment semen parameters, hormone levels, and patients' characteristics. Measurement of the number of adolescents able to cryopreserve semen. Thirteen boys were unable to produce semen by masturbation. In 53 boys semen quality was adequate for cryopreservation. In 14 patients semen analysis did not show motile spermatozoa, and therefore semen cryopreservation could not be performed. Although inhibin B showed a strong correlation with sperm count, no significant difference was found in serum T, inhibin B, LH, and FSH levels in the patients with or without successful sperm yield. Moreover, median age was not different between patients with and without a successful sperm yield. Semen cryopreservation in boys is a feasible method to preserve spermatozoa before gonadotoxic therapy is started and should be offered to all pubertal boys despite their young age. Serum hormone levels do not predict sperm yield.

Previous studies have noted a possible association between periodontal diseases and the risk of various cancers. We assessed cancer risk in a cohort of patients with moderate to severe periodontitis. Patients diagnosed with moderate to severe periodontitis by a periodontist between 2001 and 2010 were identified from the hospital registry. Patients younger than 35 years of age or with a prior cancer diagnosis were excluded. The age- and gender-standardized incidence rates (SIR) were calculated by dividing the number of observed cases by the number of expected cases from Turkish National Cancer Registry 2013 data. A total of 280 patients were included (median age 49.6, 54% female). Median follow-up was 12 years. Twenty-five new cancer cases were observed. Patients with periodontitis had 77% increased risk of cancer (SIR 1.77, 95% CI 1.17-2.58, p = .004). Women with periodontitis had significantly higher risk of breast cancer (SIR 2.40, 95% CI 0.88-5.33) and men with periodontitis had significantly higher risk of prostate cancer (SIR 3.75, 95% CI 0.95-10.21) and hematological cancers (SIR 6.97, 95% CI 1.77-18.98). Although showing a causal association necessitates further investigation, our results support the idea that periodontitis might be associated with increased cancer risk, particularly with hematological, breast and prostate cancers.

We sought to examine the short-term outcomes following single-stage repair of rectoperineal and rectovestibular fistulae in infants and identify risk factors for wound complication. Patients with a rectoperineal or rectovestibular fistula treated with a single-stage repair beyond the neonatal period (>30days of age) at a pediatric colorectal center (2011-2016) were reviewed. 36 patients with a rectoperineal and 7 patients with a rectovestibular fistula were repaired using the Posterior Sagittal Anorectoplasty (PSARP) approach. Median follow-up was 31months. The median age and weight at the time of repair were 166days and 6.5kg. Four patients (11%) suffered a wound complication (3 rectoperineal, 1 rectovestibular). Two required a diverting colostomy to allow wound healing. Two patients suffered skin separation managed with local wound care. All 4 patients experienced satisfactory wound healing without anoplasty stricture. Two different patients developed a stricture of the neo-anus. Age and weight at time of repair, gender, and presence of a genitourinary anomaly were not associated with wound complications. Delayed single-stage repair of rectoperineal and rectovestibular fistulae can be performed safely in infants beyond the newborn period. With attentive treatment, satisfactory healing can be anticipated if a wound complication is encountered. Retrospective Comparative Study, Level III. Copyright © 2018. Published by Elsevier Inc.

We aimed to understand the setting and litigation outcomes of surgical fires and operative burns. Westlaw, an online legal research data-set, was utilized. Data were collected on patient, procedure, and case characteristics. One hundred thirty-nine cases were identified; 114 (82%) operative burns and 25 (18%) surgical fires. Median plaintiff (patient) age was 46 (IQR:28-59). Most common site of operative burn was the face (26% [n = 36]). Most common source of injury was a high energy device (43% [n = 52]). Death was reported in 2 (1.4%) cases. Plaintiff age <18 vs age 18-50 and mention of a non-surgical physician as a defendant both were shown to be independently associated with an award payout (OR = 4.90 [95% CI, 1.23-25.45]; p = .02) and (OR = 4.50 [95% CI, 1.63-13.63]; p = .003) respectively. Plaintiff award payment (settlement or plaintiff verdict) was reported in 83 (60%) cases; median award payout was $215,000 (IQR: $82,000-$518,000). High energy devices remain as the most common cause of injury. Understanding and addressing pitfalls in operative care may mitigate errors and potentially lessen future liability. III.

Age is integrated in most risk stratification systems for well-differentiated thyroid cancer (WDTC). The most appropriate age threshold for stage grouping of WDTC is debatable. The objective of this study was to evaluate the best age threshold for stage grouping by comparing multivariable models designed to evaluate the independent impact of various prognostic factors, including age based stage grouping, on the disease specific survival (DSS) of our population-based cohort. Data from population-based thyroid cancer cohort of 2125 consecutive WDTC, diagnosed during 1970-2010, with a median follow-up of 11.5 years, was used to calculate DSS using the Kaplan Meier method. Multivariable analysis with Cox proportional hazard model was used to assess independent impact of different prognostic factors on DSS. The Akaike information criterion (AIC), a measure of statistical model fit, was used to identify the most appropriate age threshold model. Delta AIC, Akaike weight, and evidence ratios were calculated to compare the relative strength of different models. The mean age of the patients was 47.3 years. DSS of the cohort was 95.6% and 92.8% at 10 and 20 years respectively. A threshold of 55 years, with the lowest AIC, was identified as the best model. Akaike weight indicated an 85% chance that this age threshold is the best among the compared models, and is 16.8 times more likely to be the best model as compared to a threshold of 45 years. The age threshold of 55 years was found to be the best for TNM stage grouping. Copyright © 2015 Elsevier Ltd. All rights reserved.

Type 2 diabetes mellitus (DM2) is a chronic disease, and for treatment to succeed, it is necessary to harmonize the mental health of the patient with the environment, which impacts quality of life and adherence to medical regimens. The objetive of this study is describe the quality of life of patients with DM2 and the factors relates to its modification. This investigation was a cross-sectional study. Patients over 18 years of age with DM2 were selected. The following variables related to quality of life were studied: age, sex, occupation, marital status, years of DM2 evolution, comorbidities and presence of depression (Beck Depression Inventory). Perceived quality of life was measured with a health-related quality of life (HRQoL) scale, the 36-Item Short-Form Survey (SF-36). Patients were classified according to SF-36 HRQoL score (< 50, 51-75 and > 76 points). Among the 1394 patients included, the median age was 62 years. Global HRQoL had a median of 50.1 points. Bivariate analysis showed that age, marital status, sex, occupation, comorbidities, duration of DM2 and comorbidities had impacts on HRQoL. The logistic regression model identified age (odds ratio [OR] 1.04) and depression (OR 4.4) as independent factors that influenced overall quality of life. Patients with DM2 have poor HRQoL, which is associated with a high frequency of depression. Older age and the presence of depression impair patient HRQoL. R-2013-781-052.

2013-06-01

Reptile-associated salmonellosis (RAS) in children has been reported primarily due to direct contact with turtles, but recently also due to indirect contact with more exotic reptiles, causing disease in infants. To evaluate risk factors for RAS, we reviewed the RAS cases published in the literature since 1965. A case was defined as a child ≤18 years of age with an epidemiological link by identification of Salmonella enterica in cultures from both the affected child and the exposed reptile. We identified a total of 177 otherwise healthy children (median age 1.0 years, range 2 days to 17.0 years). RAS manifested mainly with gastrointestinal disease, but 15% presented with invasive RAS, including septicemia, meningitis, and bone and joint infection. The children with invasive RAS were significantly younger than children with noninvasive disease (median age 0.17 and 2.0 years, p<0.0001). RAS is most frequently seen after exposure to turtles (42%). However, children with invasive RAS had been exposed more often (p≤0.001) to reptiles other than turtles, including iguanas, bearded dragons, snakes, chameleons, and geckos. Children exposed to those latter reptiles usually kept indoors were younger than children exposed to turtles mostly kept outdoors (p<0.0001). RAS in children is significantly associated with invasive disease at young age, in particular infants <6 months of age. Exposure to reptiles, other than turtles, kept indoors is associated with RAS at younger age and more invasive disease. This finding is helpful for recognizing or even preventing invasive RAS in young infants that are at highest risk.

The study aimed to describe changes in the distribution of body mass index (BMI) among white non-Hispanic US men aged 40-69 years throughout the 20th century. The subjects were 12 312 randomly drawn Union Army veterans examined between 1890 and 1900, and 4059 NHANES (National Health and Nutrition Examination Survey) participants examined between 1976 and 2000. The study compared descriptive statistics of the age- and year-specific distributions of BMI. Between 1890 and 2000, median BMI of men aged 50-59 years increased by 5.7 kg/m(2) (25%), while the standard deviation almost doubled. In this age group, the current distribution of BMI is less right-skewed than in the earlier cohort. Obesity prevalence increased from 3.4% to 35%. In 1890-1894, median BMI declined with age, but by 2000 the age pattern had been reversed. The average annual growth rate of median BMI was lowest between 1900 and 1976 and has been rising to 0.5% per annum between 1988 and 2000. The increase in median BMI accounts for 75% of the rise in obesity prevalence between 1890 and 2000. The remainder must be attributed to changes in other features of the distribution, most notably the increased variance of BMI.

The individual motor elements presumed to be essential for motor development were determined from spontaneous movements involving the entire body of normal term and preterm infants. Then, diagnostic items for motor abnormality in infants with periventricular leukomalacia (PVL) were investigated. Video recordings of 24 healthy term infants, 21 normal preterm infants (8 males, 13 females; median gestational age 30 weeks; median birth weight 1216g) and 14 preterm infants with PVL (6 males, 8 females; median gestational age 30 weeks; median birth weight 1360g) were analyzed. In healthy term infants, predominant shoulder rotation was noticed until 1 month of age. After 2 months of age, isolated movements of the shoulder, elbow, hip, knee, and ankle frequently emerged. In preterm infants with PVL at the corrected age of 2 months, startle response and predominant shoulder rotation were more frequently seen and isolated neck, shoulder, elbow, hip, knee, and ankle movements were less frequently seen than in the normal preterm infants (Fisher's exact test, p<0.025). At 2 months of age, isolated movements evolve, and their failure to occur is suggested to be a useful sign for the diagnosis of cerebral motor disorders.

DNA methylation changes at a discrete set of sites in the human genome are predictive of chronological and biological age. However, it is not known whether these changes are causative or a consequence of an underlying ageing process. It has also not been shown whether this epigenetic clock is unique to humans or conserved in the more experimentally tractable mouse. We have generated a comprehensive set of genome-scale base-resolution methylation maps from multiple mouse tissues spanning a wide range of ages. Many CpG sites show significant tissue-independent correlations with age which allowed us to develop a multi-tissue predictor of age in the mouse. Our model, which estimates age based on DNA methylation at 329 unique CpG sites, has a median absolute error of 3.33 weeks and has similar properties to the recently described human epigenetic clock. Using publicly available datasets, we find that the mouse clock is accurate enough to measure effects on biological age, including in the context of interventions. While females and males show no significant differences in predicted DNA methylation age, ovariectomy results in significant age acceleration in females. Furthermore, we identify significant differences in age-acceleration dependent on the lipid content of the diet. Here we identify and characterise an epigenetic predictor of age in mice, the mouse epigenetic clock. This clock will be instrumental for understanding the biology of ageing and will allow modulation of its ticking rate and resetting the clock in vivo to study the impact on biological age.

Giant midline abdominal wall incisional herniae require repair/reconstruction to restore the structural and functional continuity of the anterior abdominal wall. We describe here our approach to these demanding cases through a combined retro-rectus mesh placement and components separation and their overall functional outcome. A retrospective analysis of a prospectively collected data was carried out and 28 patients who underwent giant (≥15 cm) midline incisional hernia reconstruction were identified in a large district general hospital between 2007 and 2013 with a median follow-up of 34 (6-76) months. Demographic data of our series include age of 60 (median) (30-87) years with a M:F ratio of 12:16, length of symptomatic hernia 18 (median) (12-36) months, more than two previous laparotomies (15), bowel obstructive symptoms (7) and recurrent herniation (7). BMI recorded was 32 (median) (24-46) and ASA of II (median) (I-III). Co-morbidities included cardiac disease (6), diabetes (6), respiratory disease (4) and systemic immunocompromise (2). Operative and technical details showed operative duration to be 180 (median) min, cranio-caudal rectus sheath defect 21 (median) cm, transverse rectus sheath defect 15 (median) cm, cross-sectional area of fascial defect 300 (median) cm(2) and size of mesh 690 (median) cm(2). Seven (25 %) developed short-term post operative complications: grade I seromata all resolving spontaneously (5); grade II superficial wound infections (2). Twenty-five (89 %) were completely asymptomatic at 34 (median) months' follow-up; 2 (7 %) reported mild pain, but not limiting any activity; 1 (4 %) described pain occasionally limiting activity. There was no clinical recurrence with one patient developing global bulging. Our series is comparable to the literature in patient cohort demographics, co-morbidity and risk factor profile; however, we demonstrate an excellent intermediate term outcome with no clinical recurrence and an improvement in quality of life, through their ability to perform normal day to day activities.

We aimed to study whether ketogenic diet (KD) therapy leads to resolution of super-refractory status epilepticus in pediatric patients without significant harm. A retrospective review was performed at Phoenix Children's Hospital on patients with super-refractory status epilepticus undergoing ketogenic diet therapy from 2011 to 2015. Ten children with super-refractory status epilepticus, ages 2-16 years, were identified. 4/10 patients had immune mediated encephalitis, including Rasmussen encephalitis, anti-N-methyl-d-aspartate receptor encephalitis, and post-infectious mycoplasma encephalitis. Other etiologies included Lennox Gastaut Syndrome, non-ketotic hyperglycinemia, PCDH19 and GABRG2 genetic epilepsy, New Onset Refractory Status Epilepticus, and Febrile Infection-Related Epilepsy Syndrome. 4/10 patients' EEG features suggested focal with status epilepticus, and 6/10 suggested generalized with status epilepticus. Median hospital length was 61days and median ICU length was 27days. The median number of antiepileptic medications prior to diet initiation was 3.0 drugs, and the median after ketogenic diet treatment was 3.5 drugs. Median duration of status epilepticus prior to KD was 18days. 9/10 patients had resolution of super-refractory status epilepticus in a median of 7days after diet initiation. 8/9 patients were weaned off anesthesia within 15days of diet initiation, and within 1day of achieving ketonuria. 1/10 patients experienced side effects on the diet requiring supplementation. Most patients achieved resolution of status epilepticus on KD therapy, suggesting it could be an effective therapy that can be utilized early in the treatment of children with super refractory status epilepticus.

Sunitinib is an oral tyrosine kinase inhibitor of VEGF, PDGF, c-KIT, and flt-3 receptors. A pediatric phase I study of sunitinib capsules identified the maximum tolerated dose as 15 mg/m(2)/day. This study was conducted to evaluate sunitinib given as a powder formulation. Sunitinib 15 mg/m(2) was administered orally daily for 4 weeks on/2 weeks off to patients <21 years old with refractory solid tumors. Sunitinib capsules were opened, and the powder sprinkled onto applesauce or yogurt. Plasma levels of sunitinib and an active metabolite, SU12662, were measured, and pharmacokinetic parameters were estimated. 12 patients, median age 13 (range 4-21) years, were treated. The most common first-cycle toxicities were leucopenia (n = 6), fatigue (n = 5), neutropenia (n = 4), and hypertension (n = 4). Three patients had dose-limiting toxicities (DLTs) in cycle 1 (dizziness/back pain, hand-foot syndrome, and intratumoral hemorrhage/hypoxia). A median peak plasma sunitinib concentration of 21 (range 6-36) ng/ml was reached at a median of 4 (range 4-8) h after the first dose. The median exposure (AUC(0-48)) was 585 (range 196-1,059) h ng/l. The median half-life was 23 (range 13-36) h. The median trough concentration measured before day 14 dosing was 32 (range 12-58) ng/ml. The pharmacokinetic profile of sunitinib appears similar between a powder formulation and published data using capsules. The powder formulation allows patients unable to swallow capsules to receive sunitinib.

Readmissions within 30-days of hospital discharge are a problem. The aim was to determine if the Better Outcomes for Older Adults through Safe Transitions (BOOST) risk assessment tool was applicable within the UK. Patients over 65 readmitted were identified retrospectively via a casenote review. BOOST assessment was applied with 1 point for each risk factor. 324 patients were readmitted (mean age 77 years) with a median of 7 days between discharge and readmission. The median BOOST score was 3 (IQR 2-4) with polypharmacy evident in 88% and prior hospitalisation in 70%. The tool correctly predicted 90% of readmissions using two or more risk factors and 99.1% if one risk factor was included. The BOOST assessment tool appears appropriate in predicting readmissions however further analysis is required to determine its precision.

Probabilistic population aging

PubMed Central

2017-01-01

We merge two methodologies, prospective measures of population aging and probabilistic population forecasts. We compare the speed of change and variability in forecasts of the old age dependency ratio and the prospective old age dependency ratio as well as the same comparison for the median age and the prospective median age. While conventional measures of population aging are computed on the basis of the number of years people have already lived, prospective measures are computed also taking account of the expected number of years they have left to live. Those remaining life expectancies change over time and differ from place to place. We compare the probabilistic distributions of the conventional and prospective measures using examples from China, Germany, Iran, and the United States. The changes over time and the variability of the prospective indicators are smaller than those that are observed in the conventional ones. A wide variety of new results emerge from the combination of methodologies. For example, for Germany, Iran, and the United States the likelihood that the prospective median age of the population in 2098 will be lower than it is today is close to 100 percent. PMID:28636675

1997-05-01

Fungal infections are an important cause of morbidity and mortality in patients with acute leukemia (AL). Candidemia, once rare, is now a common nosocomial infection because of the intensity of chemotherapy, prolonged neutropenia, administration of broad-spectrum antibiotics and use of central venous catheters (CVC). We retrospectively identified patients treated for AL from 6/86 to 6/95 who also had candidemia. We describe 28 patients (incidence 6.3%) with a median age of 39 years, 24 of whom were on remission induction and 4 on postremission chemotherapy. All patients had CVC and empiric antimicrobial therapy, 4 had been given prophylactic antifungal drugs, and 2 had parenteral nutrition. Neutropenia was profound (median leukocyte nadir 200/microliters, median duration 19 days). Candida was isolated in blood cultures 10 days (median) after the start of neutropenia. The clinical presentation included fever (100%), respiratory symptoms (71.4%), skin lesions (39.2%) and septic shock (17.8%). Amphotericin B was given to 17 patients and liposomal amphotericin to 5 patients. Infection resolved in 18 patients (64.2%). 10 of whom were in complete remission. Mortality from candidemia was 17.8% (5/28). In conclusion, fungal infections are responsible for death in a significant number of patients. In our series treatment success was related to its rapid onset and to the recovery of neutropenia.

ABSTRACT Objective: to evaluate the quality of care provided to older people with diabetes mellitus and/or hypertension in the Primary Health Care (PHC) according to the Chronic Care Model (CCM) and identify associations with care outcomes. Method: cross-sectional study involving 105 older people with diabetes mellitus and/or hypertension. The Patient Assessment of Chronic Illness Care (PACIC) questionnaire was used to evaluate the quality of care. The total score was compared with care outcomes that included biochemical parameters, body mass index, pressure levels and quality of life. Data analysis was based on descriptive statistics and multiple logistic regression. Results: there was a predominance of females and a median age of 72 years. The median PACIC score was 1.55 (IQ 1.30-2.20). Among the PACIC dimensions, the “delivery system design/decision support” was the one that presented the best result. There was no statistical difference between the medians of the overall PACIC score and individual care outcomes. However, when the quality of life and health satisfaction were simultaneously evaluated, a statistical difference between the medians was observed. Conclusion: the low PACIC scores found indicate that chronic care according to the CCM in the PHC seems still to fall short of its assumptions. PMID:29538582

The pseudotumorous form of tuberculosis is a rare entity. Whatever its location, it can simulate neoplasia by its radiological and/or endoscopic appearances. We highlight the diagnostic difficulties associated with this type of presentation. We performed a retrospective study of inpatient records from 2003 to 2016 in the pneumology department of La Rabta Hospital to identify cases of thoracic tuberculous pseudo-tumor. Seventeen patients were identified. The median age was 41 years and their symptomatology was dominated by cough and general debility. All had abnormal radiology with 10 cases of suspect lesions. Fibre-optic bronchoscopy revealed endobronchial abnormalities in 11 cases. The median overall diagnostic delay was 97 days. The diagnosis was confirmed bacteriologically in five cases, histologically in 14 cases and based on clinical presumption in one case. The progression was favourable: 13 patients have been declared cured and four patients are still undergoing treatment. Making a positive diagnosis of thoracic tuberculous pseudotumour can be difficult, as bacteriological samples are often negative. This can lead to a significant delay in diagnosis and treatment.

Management of patients with neuroendocrine tumors of the gastrointestinal tract or pancreas (GEP-NENs) poses diagnostic and therapeutic challenges. This study described the medico-legal claims reported to a national governmental system that oversees compensation to patients with GEP-NENs Materials and Methods: An electronic search of the Norwegian System of Compensation to Patients database was performed to identify claims evaluated between 2005-2016. The clinical information and the medico-legal evaluation were reviewed. We identified seven patients, five women and two men, with a median age of 57 (range=47-73) years. Delayed diagnosis (median diagnostic delay of 18 (range=6-48) months) was the main cause for claims in six out of the seven patients). Four patients received financial compensation based on the claim judgement. This review of claims that were evaluated by the Norwegian System of Compensation to Patients showed that a timely diagnosis of GEP-NENs remains a clinical challenge.

To understand the status of iodine nutrition and the affective factors of urinary iodine concentration among residents over age of 15 years in Shenzhen City. Totally 8152 residents from 73 communities were selected with stratified cluster random sampling. The morning urinary iodine was determined and the dietary assessment of iodine using a food frequency questionnaire were carried out. The range of urinary iodine was 9. 65 - 4039.09 μg/L and the median of urinary iodine was 194.59 μg/L among the residents. The percentages of the residents with urinary iodine < 50,50 - 100,100 - 199, 200 - 300, and ≥ 300 μg/L were 2.49%, 12.12%, 40.16%, 26.94% and 20.78%, respectively. There was significant difference in the medians of iodine between different gender (P = 0.0001), the medians of urinary iodine of men (201.32 μg/L) was slightly higher. There was no significant difference in urinary iodine levels (186.59 - 197.44 μg/L) among all age groups, the medians of urinary iodine of all age groups were within the recommended adequate intake. Along with the increase in age, the medians of urinary iodine of all age groups was gradually decreased. Sex, alcohol consumption and daily dietary iodine intake was significant in the final regression model. The iodine nutrition of residents in Shenzhen City was in good condition, populations with low or high iodine still exist. The monitoring is needed and the influencing factors of the urine iodine levels need much exploration.

Significant improvements in neurological function and pain relief are the benefits of aggressive surgical management of spinal metastatic disease. However, there is limited literature regarding the management of tumors with specific histological features. In this study, a series of patients undergoing spinal surgery for metastatic prostate cancer were reviewed to identify predictors of survival and functional outcome. The authors retrospectively reviewed the records of all patients who were treated with surgery for prostate cancer metastases to the spine between 1993 and 2005 at a single institution. Particular attention was given to initial presentation, operative management, clinical and neurological outcomes, and factors associated with complications and overall survival. Forty-four patients underwent a total of 47 procedures. The median age at spinal metastasis was 66 years (range 50-84 years). Twenty-four patients had received previous external-beam radiation to the site of spinal involvement, with a median dose of 70 Gy (range 30-74 Gy). Frankel scores on discharge were significantly improved when compared with preoperative scores (p = 0.001). Preoperatively, 32 patients (73%) were walking and 33 (75%) were continent. On discharge, 36 (86%) of 42 patients were walking, and 37 (88%) of 42 were continent. Preoperatively, 40 patients (91%) were taking narcotics, with a median morphine equivalent dose of 21.5 mg/day, and 28 patients (64%) were taking steroids, with a median dose of 16 mg/day. At discharge, the median postoperative morphine equivalent dose was 12 mg/day, and the median steroid dose was 0 mg/day (p < 0.001). Complications occurred in 15 (32%) of 47 procedures, with 9 (19%) considered major, and there were 4 deaths within 30 days of surgery. The median overall survival was 5.4 months. Gleason score (p = 0.002), total number of metastases (p = 0.001), and the degree of spinal canal compression (p = 0.001) were independent predictors of survival. Age > or = 65 years at the time of surgery was an independent predictor of a postoperative complication (p = 0.005). In selected patients with prostate cancer metastases to the spine, aggressive surgical decompression and spinal reconstruction is a useful treatment option. The results show that on average, neurological outcome is improved and use of analgesics is reduced. Gleason score, metastatic burden, and degree of spinal canal compression may be associated with survival following surgery, and thus should be considered carefully prior to opting for surgical management.

In the Democratic Republic of Congo, the incidence of sickle cell anemia (SCA) is estimated to affect 30,000 to 40,000 neonates per year. However, there is paucity of data on acute clinical manifestations in sickle cell children. In these circumstances, it is difficult to develop a health care policy for an adequate management of sickle cell patients. This was a seven years' retrospective study of children admitted with acute sickle cell crisis in the Department of Pediatrics in University Hospital of Kinshasa, Kinshasa, the Democratic Republic of Congo. A total of 108 patients were identified as having SCA. There were 56 (51%) girls and 52 (49%) boys. Median age was 10.5 years (range 1-24 years). No child was diagnosed by neonatal screening. The median age of diagnosis of sickle cell anemia was 90 months (range: 8-250 months). The median age at the first transfusion was 36 months (range 4-168). In this series, 61 (56.5%) patients were eligible for hydroxyurea. However, this treatment was only performed in 4 (6.6%) of them. Pain episodes, acute anemic crisis and severe infection represent respectively 38.2%, 34.3% and 21.9% of events. Altered sensorium and focal deficit were encountered occasionally and represented 3.4% of acute events. Acute renal manifestations, cholelithiasis and priapism were rarely reported, in this cohort. In Kinshasa, the care of patients suffering from sickle cell anemia is characterized by the delayed diagnosis and low detection of organ complications compared to reports of Western countries. This situation is due to resources deficiencies.

People with acquired immune deficiency syndrome (AIDS) develop ischemic stroke through distinct mechanisms. These include infections such as syphilis, tuberculosis, varicella, and other conditions such as cocaine abuse, endocarditis, and hypercoagulability. The effect of improved awareness, detection, and treatment with highly active antiretroviral therapy (HAART) on the incidence and outcome of AIDS patients with stroke is unknown. Data from the Nationwide Inpatient Sample from 1995 to 2010 were analyzed. Patients with ischemic stroke and AIDS were identified using ICD-9 (International Classification of Diseases) codes. Time trends for demographics, survival, and frequency of AIDS-associated conditions were analyzed. Proportion of AIDS among stroke patients increased significantly during the study. Median age of all strokes decreased from 75 years in 1995 to 72 years in 2010. Conversely, median age for men with stroke and AIDS increased from 43 years to 53 years; and for women with stroke and AIDS, from 41 years to 51 years. Death rates from stroke in the AIDS patients declined. In recent years, the death rates from stroke are similar to patients without HIV/AIDS. Stroke patients with AIDS had increased odds of syphilis (odds ratio [OR]: 33.50), varicella (OR: 48.34), tuberculosis (OR: 137.48), endocarditis (OR: 5.19), cocaine abuse (OR: 26.05), and hypercoagulability (OR: 4.82). In the HAART era, the median age of incident stroke in AIDS has increased and the mortality from stroke has improved. Research should focus on optimal management of dyslipidemia while on HAART. Whether HAART can reduce the incidence and improve survival of stroke needs to be explored. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

To assess WINROP (https://winrop.com), an algorithm using postnatal weight measurements, as a tool for the prediction of retinopathy of prematurity (ROP) in a large geographically and racially diverse study population. WINROP analysis was performed retrospectively on conventionally at-risk infants from 10 neonatal intensive careunits.Weight measurements were entered into WINROP, which signals an alarm for an abnormal weight gain rate. Infants were classified into categories of no alarm (unlikely to develop type 1ROP)and alarm (at risk for developing type 1ROP).Use of WINROP requires that an infant has (1) gestational age less than 32 weeks at birth, (2) weekly weight measurements,(3) physiologic weight gain,and(4)absence of other pathologic retinal vascular disease. A total of 1706 infants with a median gestational age of 28 weeks (range, 22-31 weeks) and median birth weight of 1016 g (range, 378-2240 g) were included in the study analysis. An alarm occurred in 1101 infants (64.5%), with a median time from birth to alarm of 3 weeks (range, 0-12 weeks) and from alarm to treatment of 8 weeks (range, 1 day to 22 weeks). The sensitivity of WINROP was 98.6% and the negative predictive value was 99.7%. Two infants with type 1 ROP requiring treatment after 40 weeks' postmenstrual age did not receive an alarm. The WINROP system is a useful adjunct for ROP screening that identifies high-risk infants early to optimize care and potentially reduce the overall number of diagnostic ROP examinations.

Sertoli and Leydig cell tumors (SCT and LCT) are uncommon testis neoplasms. Data regarding patient demographics and outcomes are limited to small series. We further characterized these tumors using a large cancer database. The Surveillance, Epidemiology, and End Results (SEER) database was queried from 2004 to 2012. International Classification of Diseases for Oncology (ICD-O) codes identified SCT and LCT. Common germ cell tumors (GCT) provided a reference group. Age, race, histology, tumor size, stage, and cancer-specific mortality (CSM) were compared. Thirty-one men had SCT, 76 had LCT, and 17,998 had GCTs. Median follow-up for SCT, LCT, and GCTs was 46, 38, and 50 months, respectively. Median ages for SCT and LCT were 39 and 47, respectively, which was older than those with GCT (34 years; P < .001). African American race was more common in SCT (23%) and LCT (24%) patients compared to GCT (3%, P < .001). LCT most commonly presented with stage I disease (98.5%), while patients with SCT presented at higher stages (35% with stage II/III). CSM was highest in patients with SCT (32% vs. 2% LCT and 7% GCT, P < .001). Median survival of those with CSM was similar between SCT, LCT, and GCTs (15, 12, and 14 months, respectively). Compared to GCT, SCT and LCT present at older ages and are more common in African Americans. Metastasic disease at presentation and CSM rates are higher in SCT compared to LCT and GCT, suggesting a clinically relevant distinction between these histologies. Better characterization of these rare neoplasms will continue to inform patient counseling and management. Copyright © 2016 Elsevier Inc. All rights reserved.

To evaluate the frequency of subclinical lead toxicity. Cross-sectional study. Department of Pathology and Laboratory Medicine, The Aga Khan University Hospital, Karachi, from January 2011 to December 2014. Analysis of laboratory data for blood lead levels (BLL) was performed. Lead was tested by atomic absorption spectrometer. For all subjects, only initial test results were included while the results of repeated testing were excluded. Exemption was sought from institutional ethical review committee. BLL of 2-10 ug/dl and 10-70 ug/dl in children and adults, respectively were taken as subclinical lead toxicity. Amongst the total number of subjects tested (n=524), 26.5% (n=139) were children (<16 years) while rest were adults. Overall median BLLs was 6.4 ug/dl (20.9-3.1). The median BLL was 4 ug/dl (6.7-2.6) in children and 8.3 ug/dl (27.9-3.4) in adults, respectively. The BLL increased with age; higher levels were observed in age range 21-30 years of subjects [median lead level 16.9 ug/dl (36.1-4)] and lower level [4.2 ug/dl (6.8-2.6)] in children with <10 years of age. Only 16% (n=22) children had desirable lead levels while most had either subclinical (76%, n=106) or toxic lead levels (8%, n=11). In adults, (55%, n=212) subjects had desired lead levels, and 40% (n=154) and 4.99% (n=19) had subclinical and toxic lead levels. Presence of subclinical lead poisoning even after phasing out of lead petroleum in Pakistanis is alarming, especially in children. A national population-based study to determine the lead status and targeted intervention to identify potential sources is need of the time.

Background By 2011, South African prevention of mother-to-child transmission of HIV (PMTCT) programmes had reduced perinatal HIV transmission at 6-weeks of age to 2.7%. We investigated the profile of newly-diagnosed vertically-infected children and their mothers to identify short-falls in the PMTCT programme. Methods In this operational follow-up study, fieldworkers enrolled mothers of newly-diagnosed HIV-infected children up to 2 years of age at 5 major healthcare facilities in Johannesburg. Structured questionnaires and clinical record reviews were conducted and analysed to describe the population and assess factors associated with PMTCT uptake. Results 289 mother-child pairs were enrolled. Timing of maternal HIV diagnosis influenced PMTCT access and feeding choices, and was associated with infants’ age at HIV diagnosis (7 weeks vs. 11 weeks vs. 31 weeks where mothers tested before, during or after the pregnancy respectively; p <0.0001). Women diagnosed before pregnancy (12%) were older (median 31 years) than those diagnosed during the index pregnancy (53% - median 27 years). Women diagnosed after delivery (35%) were younger (median 25 years, p<0.0001), of lower parity, and less likely to be South African citizens. In 81 cases (29%) late maternal diagnosis precluded any PMTCT access. Where women were diagnosed during or before pregnancy, the recommended PMTCT guidelines for mother and infant were followed in 86 (61%) pairs. Conclusion Failure to diagnose maternal HIV infection before delivery was the main reason for missing PMTCT prophylaxis and early infant testing. Timely maternal diagnosis enables PMTCT uptake, but implementation and follow-up gaps require attention to improve infant outcomes. PMID:24759066

To investigate the self-reported quality of sleep of non-mechanically ventilated patients admitted to an ICU, and to identify barriers to sleep in this setting. Patients admitted to the ICU of Frankston Hospital over a two month period who had spent at least one night in the ICU, and had not received mechanical ventilation were surveyed as they were discharged from the ICU. This survey required patients to rate the quality of their sleep in the ICU and at home immediately prior to hospitalisation on a 10cm visual analogue scale; and to identify perceived barriers to sleep in the ICU and at home prior to hospitalisation. 56 respondents were surveyed during the study period. Median age was 74 years (range=18-92 years); median ICU length of stay was 1 day (range=1-7 days). Overall, respondents rated their quality of sleep in ICU (median=4.9/10) as significantly worse than at home immediately prior to ICU admission (median=7.15/10; Z=-3.02, p<0.002); however 44% of respondents rated their quality of sleep in ICU as better, or no worse, than at home immediately prior to hospitalisation. Sub-group analysis revealed that among patients with reduced quality of sleep (<5/10) prior to hospitalisation, 71.4% rated their quality of sleep in ICU as better, or no worse, than at home prior to hospitalisation, with no significant difference between sleep quality ratings in ICU and at home (p=0.341). Respondents identified the following as barriers to sleep in the ICU: noise levels overnight (53.6%); discomfort (33.9%); pain (32.1%); being awoken for procedures (32%); being attached to medical devices (28.6%); stress/anxiety (26.8%); and light levels (23.2%). Pre-hospitalisation sleep quality appears to be an important influence on sleep in ICU. Many barriers to sleep in the ICU identified by respondents are potentially modifiable.

Using a somatosensory version of the oddball-paradigma the influence of age and gender on the P300-component and the comparison of the potential after stimulation of the right and left median nerve was studied in 30 healthy right handed volunteers (age: 20-35 years). Latency, amplitude, area and duration of the P300-potential were analysed. No relationship between age, gender and the P300-parameters were observed. The amplitude and the area of the potential obtained from the F3 electrode were greater after stimulation of the right median nerve compared to the potential after stimulation of the left median nerve. All other results were not significantly different. Strong positive correlations between the results after stimulation of the right and left median nerve were observed. These results showed that by a young group of volunteers age and gender did not influence the P300-component. Although the P300-Parameters had a between-subject variability, their mean remained constant over the study, their correlation coefficients were strong positive and the side of stimulation did not influence them (except for the electrode F3).

Fewer than 30% of U.S. youth meet the recommendation to be active ≥ 60 minutes/day. Access to parks may encourage higher levels of physical activity. To examine differences in park access among U.S. school-age youth, by demographic characteristics and urbanicity of block group. Park data from 2012 were obtained from TomTom, Incorporated. Population data were obtained from the 2010 U.S. Census and American Community Survey 2006-2010. Using a park access score for each block group based on the number of national, state or local parks within one-half mile, we examined park access among youth by majority race/ethnicity, median household income, median education, and urbanicity of block groups. Overall, 61.3% of school-age youth had park access--64.3% in urban, 36.5% in large rural, 37.8% in small rural, and 35.8% in isolated block groups. Park access was higher among youth in block groups with higher median household income and higher median education. Urban youth are more likely to have park access. However, park access also varies by race/ethnicity, median education, and median household. Considering both the demographics and urbanicity may lead to better characterization of park access and its association with physical activity among youth.

Despite the existence of evidence-based guidelines for the care of children with diabetes, widespread gaps in knowledge, attitude, and practice remain. The purpose of this paper is to present a review of benchmarking practices and results of this process within SWEET, moreover focusing on current challenges and future directions. Biannually, members electronically transfer de-identified clinic data for 37 parameters to the SWEET database. Each center receives benchmarking and data validation reports. In 2015, 48 centers have contributed data for 20 165 unique patients (51.6% male). After exclusion for missing data 19 131 patients remain for further analysis. The median age is 14.2 years, with a median diabetes duration 4.8 years; 96.0% of patients have type 1, 1.1% type 2, and 2.9% other diabetes types. Data completeness has increased over time. In 2015, median HbA1c of all patients' (diabetes type 1) medians was 7.8% (61.7 mmol/mol) with 39.1%, 41.4%, and 19.4% of patients having HbA1c < 7.5% (58 mmol/mol), 7.5%-9% (58-75 mmol/mol) and >9% (75 mmol/mol), respectively. Although HbA1c has been stable over time [7.7%-7.8% (60.7-61.7 mmol/mol)], there remains wide variation between centers. Fourteen centers achieve a median HbA1c <7.5% (58 mmol/mol). Our vision is that the participation in SWEET is encouraging members to deliver increasingly accurate and complete data. Dissemination of results and prospective projects serve as further motivation to improve data reporting. Comparing processes and outcomes will help members identify weaknesses and introduce innovative solutions, resulting in improved and more uniform care for patients with diabetes. © 2016 John Wiley & Sons A/S.

Ultrasound (US) measurement of the median nerve cross-sectional area (CSA) at the wrist is a useful diagnostic test for carpal tunnel syndrome (CTS). We compared median nerve normal values between samples of Indian and Dutch populations. The median nerve was examined by US at the wrist in 100 healthy volunteers in India and 137 volunteers in The Netherlands using the same protocol. Median nerve CSA at the wrist (7.0 ± 1.1 mm(2)) in the Indian cohort was lower in comparison to the Dutch cohort (8.3 ± 1.9 mm(2) ; P < 0.05). This difference was still present after controlling for age, height, and weight (P = 0.001). CSA normal values for the median nerve were different between the examined population samples even after correcting for age, height, and weight. This enforces the idea that laboratories around the world should obtain their own normative data. Copyright © 2013 Wiley Periodicals, Inc.

A plastic anemia is a rare life-threatening disease. However, since the introduction of immunosuppressive therapy and allogeneic stem cell transplantation, the outcome has improved considerably, and the 5-year survival is reported to be 70–80% in selected patient cohorts. Yet, contemporary population-based data on incidence and survival are lacking. We performed a national retrospective study to determine the incidence, treatment, and survival of patients with aplastic anemia diagnosed in Sweden from 2000–2011. Patients were included via the National Patient Registry, and diagnosed according to the Camitta criteria. In total, 257 confirmed cases were identified, with an overall incidence of 2.35 (95% CI: 2.06–2.64) cases per million inhabitants per year. Median age was 60 years (range: 2–92), and median follow up was 76 (0–193) months. Primary treatments included immunosuppressive therapy (63%), allogenic stem cell transplantation (10%), or single-agent cyclosporine/no specific therapy (27%). The 5-year survival was 90.7% in patients aged 0–18 years, 90.5% in patients aged 19–39 years, 70.7% in patients aged 40–59 years, and 38.1% in patients aged ≥60 years. Multivariate analysis showed that age (both 40–59 and ≥60 age groups), very severe aplastic anemia and single-agent cyclosporine/no specific therapy were independent risk factors for inferior survival. In conclusion, younger aplastic anemia patients experience a very good long-term survival, while that of patients ≥60 years in particular remains poor. Apparently, the challenge today is to improve the management of older aplastic anemia patients, and prospective studies to address this medical need are warranted. PMID:28751565

Children with benign epilepsy with centrotemporal spikes (BECTS) have traditionally been considered to have a uniformly good prognosis. However, benign may be a misnomer because BECTS is linked to cognitive deficits, a more severe phenotype with intractable seizures, and the potential for sudden unexpected death in epilepsy (SUDEP). To determine if cases of BECTS are present in the North American SUDEP Registry (NASR). The NASR is a clinical and biospecimen repository established in 2011 to promote SUDEP research. The NASR database, which includes medical records, results of electroencephalographic tests, and interviews with family members of patients with epilepsy who died suddenly without other identifiable causes of death, was queried from June 3, 2011, to June 3, 2016, for cases of BECTS. The patients with epilepsy had died suddenly without other identifiable causes of death (eg, drowning, trauma, exposure to toxic substances, or suicide); SUDEP classification was determined by the consensus of 2 epileptologists. Cases of SUDEP among children who received a diagnosis of BECTS among patients reported in the NASR. Three boys (median age at death, 12 years; range, 9-13 years) who received a diagnosis of BECTS by their pediatric epileptologist or neurologists were identified among 189 cases reported in the NASR. The median age of epilepsy onset was 5 years (range, 3-11 years), and the median duration of epilepsy was 4 years (range, 1-10 years). Two deaths were definite SUDEP, and 1 was probable SUDEP. Independent review of clinical and electroencephalographic data supported the diagnosis of BECTS in all 3 patients. None of the patients was prescribed antiseizure drugs, either owing to physician recommendation or mutual decision by the physician and parents. All 3 patients were found dead in circumstances typical of SUDEP. The 3 patients spanned the spectrum of BECTS severity: 1 had only a few seizures, 1 had more than 30 focal motor seizures, and 1 had 4 witnessed generalized tonic-clonic seizures and approximately 30 suspected generalized tonic-clonic seizures. Sudden unexpected death in epilepsy is a very rare outcome in BECTS that clinicians should consider discussing in appropriate circumstances and possibly factoring into treatment decisions.

Current evidence suggests that type 2 diabetes may have a greater impact on those with earlier diagnosis (longer duration of disease), but data are limited. We examined the effect of age at diagnosis of type 2 diabetes on the risk of all-cause and cause-specific mortality over 15 years. The data of 743,709 Australians with type 2 diabetes who were registered on the National Diabetes Services Scheme (NDSS) between 1997 and 2011 were examined. Mortality data were derived by linking the NDSS to the National Death Index. All-cause mortality and mortality due to cardiovascular disease (CVD), cancer and all other causes were identified. Poisson regression was used to model mortality rates by sex, current age, age at diagnosis, diabetes duration and calendar time. The median age at registration on the NDSS was 60.2 years (interquartile range [IQR] 50.9-69.5) and the median follow-up was 7.2 years (IQR 3.4-11.3). The median age at diagnosis was 58.6 years (IQR 49.4-67.9). A total of 115,363 deaths occurred during 7.20 million person-years of follow-up. During the first 1.8 years after diabetes diagnosis, rates of all-cause and cancer mortality declined and CVD mortality was constant. All mortality rates increased exponentially with age. An earlier diagnosis of type 2 diabetes (longer duration of disease) was associated with a higher risk of all-cause mortality, primarily driven by CVD mortality. A 10 year earlier diagnosis (equivalent to 10 years' longer duration of diabetes) was associated with a 1.2-1.3 times increased risk of all-cause mortality and about 1.6 times increased risk of CVD mortality. The effects were similar in men and women. For mortality due to cancer (all cancers and colorectal and lung cancers), we found that earlier diagnosis of type 2 diabetes was associated with lower mortality compared with diagnosis at an older age. Our findings suggest that younger-onset type 2 diabetes increases mortality risk, and that this is mainly through earlier CVD mortality. Efforts to delay the onset of type 2 diabetes might, therefore, reduce mortality.

Babies and bearded dragons: sudden increase in reptile-associated Salmonella enterica serovar Tennessee infections, Germany 2008.

In 2008 a marked increase in Salmonella enterica serovar Tennessee infections in infants occurred in Germany. In March and April 2008, eight cases were notified compared to a median of 0-1 cases in 2001-2006. We carried out an investigation including a case-control study to identify the source of infection. A patient was a child < 3 years of age with Salmonella Tennessee isolated from stool from September 1, 2007, through December 31, 2008, identified through the national surveillance system. A control was a child with a notified rotavirus infection in the matching district, frequency matched by age group. We conducted telephone interviews on feeding, herbal infusions, and animal contact. Matched odds ratios (mOR) were calculated using exact conditional logistic regression. For Salmonella Tennessee isolates, pulsed-field gel electrophoresis and multiple-locus variable number tandem repeat analysis were performed. Further cloacal swab samples of reptiles kept in case households were investigated. We identified 18 cases < 3 years. Ten children were male; median age was 3 months (1-32 months). In 8 of 16 case households reptiles were kept. Direct contact between child and reptile was denied. Other forms of reptile contact were reported in four of the remaining eight households. Ten case- and 21 control-patients were included in the study. Only keeping of a reptile and "any reptile contact" were associated with Salmonella Tennessee infection (mOR 29.0; 95% CI 3.1 ± ∞ and mOR 119.5; 95% CI 11.7 - ∞). Identical Salmonella Tennessee strains of child and reptile kept in the same household could be shown in 2 cases. Reptiles were the apparent source of Salmonella Tennessee infection in these infants. Indirect contact between infants and reptiles seems to be sufficient to cause infection and should therefore be avoided.

C3 glomerulopathy is a form of complement-mediated GN. Immunosuppressive therapy may be beneficial in the treatment of C3 glomerulopathy. Mycophenolate mofetil is an attractive treatment option given its role in the treatment of other complement-mediated diseases and the results of the Spanish Group for the Study of Glomerular Diseases C3 Study. Here, we study the outcomes of patients with C3 glomerulopathy treated with steroids and mycophenolate mofetil. We conducted a retrospective chart review of patients in the C3 glomerulopathy registry at Columbia University and identified patients treated with mycophenolate mofetil for at least 3 months and follow-up for at least 1 year. We studied clinical, histologic, and genetic data for the whole group and compared data for those who achieved complete or partial remission (responders) with those who did not achieve remission (nonresponders). We compared remission with mycophenolate mofetil with remission with other immunosuppressive regimens. We identified 30 patients who met inclusion criteria. Median age was 25 years old (interquartile range, 18-36), median creatinine was 1.07 mg/dl (interquartile range, 0.79-1.69), and median proteinuria was 3200 mg/g creatinine (interquartile range, 1720-6759). The median follow-up time was 32 months (interquartile range, 21-68). Twenty (67%) patients were classified as responders. There were no significant differences in baseline characteristics between responders and nonresponders, although initial proteinuria was lower (median 2468 mg/g creatinine) in responders compared with nonresponders (median 5000 mg/g creatinine) and soluble membrane attack complex levels were higher in responders compared with nonresponders. For those tapered off mycophenolate mofetil, relapse rate was 50%. Genome-wide analysis on complement genes was done, and in 12 patients, we found 18 variants predicted to be damaging. None of these variants were previously reported to be pathogenic. Mycophenolate mofetil with steroids outperformed other immunosuppressive regimens. Among patients who tolerated mycophenolate mofetil, combination therapy with steroids induced remission in 67% of this cohort. Heavier proteinuria at the start of therapy and lower soluble membrane attack complex levels were associated with treatment resistance. Copyright © 2018 by the American Society of Nephrology.

Background Body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) are used in screening and predicting obesity in adults. However, the best identifier of metabolic complications in children with obesity remains unclear. This study evaluated lipid profile distribution and investigated the best anthropometric parameter in association with lipid disorders in children with obesity. Methods A total of 2243 school children aged 7–17 years were enrolled in Guangzhou, China, in 2014. The anthropometric indices and lipid profiles were measured. Dyslipidemia was defined according to the US Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents. The association between anthropometry (BMI, WC, and WHR) and lipid profile values was examined using chi-square analysis and discriminant function analysis. Information about demography, physical activity, and dietary intake was provided by the participant children and their parents. Results Children aged 10–14 and 15–17 years old generally had higher triglyceride values but lower median concentration of total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol compared with children aged 7–9 years old (all P < 0.001). These lipid parameters fluctuated in children aged 10–14 years old. The combination of age groups, BMI, WC and WHR achieved 65.1% accuracy in determining dyslipidemic disorders. BMI correctly identified 77% of the total dyslipidemic disorders in obese children, which was higher than that by WHR (70.8%) (P< 0.05). Conclusion The distribution of lipid profiles in Chinese children differed between younger and older age groups, and the tendency of these lipid levels remarkably fluctuated during 10 to 14 years old. BMI had better practical utility in identifying dyslipidemia among school-aged children with obesity compared with other anthropometric measures. PMID:26963377

To assess the ability of prenatal ultrasound (US) in identifying systemic feeding arteries in bronchopulmonary sequestrations and hybrid lesions and report the ability of US in classifying bronchopulmonary sequestrations as intralobar or extralobar. Institutional Review Board-approved radiology and clinical database searches from 2008 to 2015 were performed for prenatal lung lesions with final diagnoses of bronchopulmonary sequestrations or hybrid lesions. All patients had detailed US examinations, and most patients had ultrafast magnetic resonance imaging (MRI). Lesion location, size, and identification of systemic feeding arteries and draining veins were assessed with US. The study consisted of 102 bronchopulmonary sequestrations and 86 hybrid lesions. The median maternal age was 30 years. The median gestational age was 22 weeks 5 days. Of bronchopulmonary sequestrations, 66 had surgical pathologic confirmation, and 100 had postnatal imaging. Bronchopulmonary sequestration locations were intrathoracic (n = 77), intra-abdominal (n = 19), and transdiaphragmatic (n = 6). Of hybrid lesions, 84 had surgical pathologic confirmation, and 83 had postnatal imaging. Hybrid lesion locations were intrathoracic (n = 84) and transdiaphragmatic (n = 2). Ultrasound correctly identified systemic feeding arteries in 86 of 102 bronchopulmonary sequestrations and 79 of 86 hybrid lesions. Of patients who underwent MRI, systemic feeding arteries were reported in 62 of 92 bronchopulmonary sequestrations and 56 of 81 hybrid lesions. Ultrasound identified more systemic feeding arteries than MRI in both bronchopulmonary sequestrations and hybrid lesions (P < .01). Magnetic resonance imaging identified systemic feeding arteries that US did not in only 2 cases. In cases in which both systemic feeding arteries and draining veins were identified, US could correctly predict intrathoracic lesions as intralobar or extralobar in 44 of 49 bronchopulmonary sequestrations and 68 of 73 hybrid lesions. Ultrasound is most accurate for systemic feeding artery detection in bronchopulmonary sequestrations and hybrid lesions and can also type the lesions as intralobar or extralobar when draining veins are evaluated. © 2017 by the American Institute of Ultrasound in Medicine.

Purpose: To identify the prognostic factors for spinal cord astrocytoma and determine the effects of surgery and radiotherapy on outcome. Methods and Materials: This retrospective study reviewed the cases of consecutive patients with spinal cord astrocytoma treated at Mayo Clinic Rochester between 1962 and 2005. Results: A total of 136 consecutive patients were identified. Of these 136 patients, 69 had pilocytic and 67 had infiltrative astrocytoma. The median follow-up for living patients was 8.2 years (range, 0.08-37.6), and the median survival for deceased patients was 1.15 years (range, 0.01-39.9). The extent of surgery included incisional biopsy only (59%), subtotal resectionmore » (25%), and gross total resection (16%). Patients with pilocytic tumors survived significantly longer than those with infiltrative astrocytomas (median overall survival, 39.9 vs. 1.85 years; p < 0.001). Patients who underwent resection had a worse, although nonsignificant, median survival than those who underwent biopsy only (pilocytic, 18.1 vs. 39.9 years, p = 0.07; infiltrative, 19 vs. 30 months, p = 0.14). Postoperative radiotherapy, delivered in 75% of cases, gave no significant survival benefit for those with pilocytic tumors (39.9 vs. 18.1 years, p = 0.33) but did for those with infiltrative astrocytomas (24 vs. 3 months; Wilcoxon p = 0.006). On multivariate analysis, pilocytic histologic type, diagnosis after 1984, longer symptom duration, younger age, minimal surgical extent, and postoperative radiotherapy predicted better outcome. Conclusion: The results of our study have shown that histologic type is the most important prognostic variable affecting the outcome of spinal cord astrocytomas. Surgical resection was associated with shorter survival and thus remains an unproven treatment. Postoperative radiotherapy significantly improved survival for patients with infiltrative astrocytomas but not for those with pilocytic tumors.« less

Watchful waiting (WW) is an acceptable strategy for managing prostate cancer (PC) in older men. Prostate-specific antigen (PSA) testing has resulted in a stage migration, with diagnoses made in younger men. An analysis of the Department of Defense Center for Prostate Disease Research Database was undertaken to document younger men with low- or intermediate-grade PC who initially chose WW. We identified men choosing WW who were diagnosed between January 1991 and January 2002, were 70 years or younger, had a Gleason score < or = 6 with no Gleason pattern 4, had no more than three positive cores on biopsy, and whose clinical stage was < or = T2 and PSA level was < or = 20. We analyzed their likelihood of remaining on WW, the factors associated with secondary treatment, and the influence of comorbidities. Three hundred thirteen men were identified. Median follow-up time was 3.8 years. Median age was 65.4 years (range, 41 to 70 years). Ninety-eight patients remained on WW; 215 proceeded to treatment. A total of 57.3% and 73.2% chose treatment within the first 2 and 4 years, respectively. Median PSA doubling time (DT) was 2.5 years for those who underwent therapy; those remaining on WW had a median DT of 25.8 years. The type of secondary treatment was associated with the number of patient's comorbidities (P =.012). Younger patients who choose WW seemed more likely to receive secondary treatment than older patients. PSA DTs often predict the use of secondary treatment. The number of comorbidities a patient has influences the type of secondary therapy chosen. The WW strategy may better be termed temporarily deferred therapy.

Background The licensed intravenous acetylcysteine regimen for treating paracetamol overdose in most countries uses three separate infusions over 21 h. This complex regimen, requiring different infusion concentrations and rates, has been associated with administration errors. The aim of the present study was to assess the extent of administration delays occurring during this acetylcysteine regimen. Method A 6‐month retrospective observational study was conducted at three English teaching hospitals with clinical toxicology services from October 2014. Patients aged 16 years and over, treated with intravenous acetylcysteine for paracetamol overdose, were included. The start times for infusions were recorded and the delays compared with the prescribed infusion times were calculated. Anaphylactoid reactions, intravenous cannula problems, overdose intent and smoking status were recorded to assess their contribution to delays. Results From 263 cases identified, 198 met the study inclusion criteria. The median time between the start of infusions 1 and 3 was delayed from the intended 5 h by a median (interquartile range) of 90 (50–163) min, with 135 (68%) cases delayed by more than 1 h. Significantly longer delays were observed in patients with anaphylactoid reactions [median delay 267 (217–413) min, n = 8] and accidental/supratherapeutic overdose [median delay 170 (95–260) min, n = 29]. There were no significant differences between smokers and nonsmokers, or for patients with intravenous cannula problems. Conclusion Long delays were identified during the three‐infusion acetylcysteine regimen for the treatment of paracetamol overdose. These were of clinical significance and could lead to periods of subtherapeutic plasma acetylcysteine concentrations and potentially avoidable hepatotoxicity, as well as delaying hospital discharge.

We evaluated the diagnostic and prognostic value of quantification of myocardial flow reserve (MFR) with positron emission tomography (PET) in orthotopic heart transplant patients. We retrospectively identified orthotopic heart transplant patients who underwent rubidium-82 cardiac PET imaging. The primary outcome was the composite of cardiovascular death, acute coronary syndrome, coronary revascularization, and heart failure hospitalization. Cox regression was used to evaluate the association of MFR with the primary outcome. The relationship of MFR and cardiac allograft vasculopathy severity in patients with angiography within 1 year of PET imaging was assessed using Spearman rank correlation and logistic regression. A total of 117 patients (median age, 60 years; 71% men) were identified. Twenty-one of 62 patients (34%) who underwent angiography before PET had cardiac allograft vasculopathy. The median time from orthotopic heart transplant to PET imaging was 6.4 years (median global MFR, 2.31). After a median of 1.4 years, 22 patients (19%) experienced the primary outcome. On an unadjusted basis, global MFR (hazard ratio, 0.22 per unit increase; 95% confidence interval, 0.09-0.50; P <0.001) and stress myocardial blood flow (hazard ratio, 0.48 per unit increase; 95% confidence interval, 0.29-0.79; P =0.004) were associated with the primary outcome. Decreased MFR independently predicted the primary outcome after adjustment for other variables. In 42 patients who underwent angiography within 12 months of PET, MFR and stress myocardial blood flow were associated with moderate-severe cardiac allograft vasculopathy (International Society of Heart and Lung Transplantation grade 2-3). MFR assessed by cardiac rubidium-82 PET imaging is a predictor of cardiovascular events after orthotopic heart transplant and is associated with cardiac allograft vasculopathy severity. © 2018 American Heart Association, Inc.

To evaluate outcome and adverse events following ventral stabilization of the atlantoaxial (AA) joint in dogs with clinical AA subluxation using screw/polymethymethacrylate (PMMA) constructs in a retrospective, multi-center cohort study. Historical cohort study. 35 client-owned dogs. Medical records from 3 institutions were reviewed to identify dogs with AA subluxation treated with ventral screw and PMMA constructs. Data on signalment, pre- and postoperative neurologic status, imaging performed, and adverse events were retrieved. Neurologic examination data were abstracted to generate a modified Frankel score at admission, discharge, and re-examination. Telephone interview of owners >180 days postoperative was conducted. Thirty-five dogs with AA subluxation treated with ventral screw/PMMA constructs were included. Most dogs were young (median age 1 year), small breed dogs with acute onset of neurologic signs (median duration 22.5 hours). Most dogs were non-ambulatory at the time of admission (median modified Frankel score 3). Adverse events were identified in 15/35 dogs including 9 dogs with major adverse events. Four dogs required a second surgery due to vertebral canal violation (n = 2) or implant failure (n = 2). Re-examination at 4-6 weeks postoperative reported 15/28 dogs with improved neurologic status and 19/28 dogs were ambulatory. Telephone follow-up was available for 23/35 dogs with 23/23 reported as ambulatory (median follow-up 390 days). Ventral application of screw and PMMA constructs for AA subluxation, as described here, is associated with clinical improvement in the majority of dog. Major adverse events are infrequent and the technique is considered relatively safe. © Copyright 2016 by The American College of Veterinary Surgeons.

Primary retroperitoneal mucinous cystadenocarcinoma (PRMCa) is a rare tumour. Prognosis and optimal management are not well established. In view of a case managed in our Centre, we performed a systematic review and meta-analysis. Systematic review of medical electronic databases for published data (1950-12/10/2015). No RCTs identified. Individual patient data detracted from case reports and case series were analysed In total, 73 female and 5 male cases of PRMCa identified including our case. Median age at diagnosis was 42.0 years (range 18-86 years), with women being significantly younger than men at diagnosis (42.0 years versus 62.2 years, p = 0.005). A palpable abdominal mass and abdominal pain were the most common presentations in 42.9 and 23.8 % of cases, respectively. Twenty-six women were <38 years old. There were 16 women <38 years old that had surgical data reported, of which 14 underwent fertility-sparing surgery with excision of the mass. Adjuvant chemotherapy was given in 24.1 % (13/72) women. Follow-up ranged from 1 to 130 months with a median of 15 months. Of the 57 cases that had follow-up reported, recurrence occurred in 23 cases (40.4 %) within a median of 8 months from diagnosis. Median disease-free survival was 15 months (range 1-130 months). Of the women who recurred, 14 died of their disease giving 1, 2 and 5-year disease-specific survival rates of 85.9, 80.7 and 75.4 %, respectively. PRMCa are rare and potentially aggressive tumours that often occur in young women. Removal of the tumour, adequate staging and adjuvant chemotherapy needs to be considered.

Timeliness of cancer treatment is an important aspect of health care quality. Veterans Affairs Medical Centers (VAMCs) are expected to treat a growing number of patients with cancer. Our objectives were to examine treatment times from diagnosis to first-course therapy for patients with colon and rectal cancers and assess factors associated with prolonged wait times. From the VA Central Cancer Registry, patients who underwent colon or rectal resection for cancer from 1998 to 2008 were identified. Time from diagnosis to definitive cancer-directed therapy was measured, and multivariable regression methods were used to determine predictors of prolonged wait times for colon (≥ 45 days) and rectal (≥ 60 days) cancers. From 124 VAMCs, 14,097 patients underwent colectomy, and 3,390 underwent rectal resection for cancer. For colon cancer, the median time to treatment increased by 68% over time (P < .001). From 2007 to 2008, the median time to colectomy was 32 days. Predictors of prolonged wait times included age ≥ 55 years (v < 55 years), time period (2007 to 2008 v 1998 to 2000), black race (v white), marriage status (married v unmarried), high-volume center status (v low volume), and treatment at a different hospital (v same hospital as initial diagnosis; all P < .05). For rectal cancer, the overall median time to first-course treatment increased by 74% (P < .001). From 2007 to 2008, the median time to proctectomy was 47 days. Similar predictors of prolonged wait times were identified for rectal cancer. Time to first treatment has increased for patients with colon and rectal cancers at VAMCs. Patient, tumor, and hospital factors are associated with prolonged time to treatment.

Purpose: Radiotherapy plays a central role in the definitive treatment of glioblastoma. However, the optimal management of elderly patients with glioblastoma remains controversial, as the relative benefit in this patient population is unclear. To better understand the role that radiation plays in the treatment of glioblastoma in the elderly, we analyzed factors influencing patient survival using a large population-based registry. Methods and Materials: A total of 2,836 patients more than 70 years of age diagnosed with glioblastoma between 1993 and 2005 were identified from the Surveillance, Epidemiology, and End Results (SEER) registry. Demographic and clinical variables used in the analysismore » included gender, ethnicity, tumor size, age at diagnosis, surgery, and radiotherapy. Cancer-specific survival and overall survival were evaluated using the Kaplan-Meier method. Univariate and multivariate analysis were performed using Cox regression. Results: Radiotherapy was administered in 64% of these patients, and surgery was performed in 68%. Among 2,836 patients, 46% received surgery and radiotherapy, 22% underwent surgery only, 18% underwent radiotherapy only, and 14% did not undergo either treatment. The median survival for patients who underwent surgery and radiotherapy was 8 months. The median survival for patients who underwent radiotherapy only was 4 months, and for patients who underwent surgery only was 3 months. Those who received neither surgery nor radiotherapy had a median survival of 2 months (p < 0.001). Multivariate analysis showed that radiotherapy significantly improved cancer-specific survival (hazard ratio [HR], 0.43, 95% confidence interval [CI] 0.38-0.49) after adjusting for surgery, tumor size, gender, ethnicity, and age at diagnosis. Other factors associated with Cancer-specific survival included surgery, tumor size, age at diagnosis, and ethnicity. Analysis using overall survival as the endpoint yielded very similar results. Conclusions: Elderly patients with glioblastoma who underwent radiotherapy had improved cancer-specific survival and overall survival compared to patients who did not receive radiotherapy.« less

To identify predictors of outcome and of electrophysiologic recovery in patients with carpal tunnel syndrome (CTS) treated by endoscopic carpal tunnel release using a nerve conduction testing system (NC-Stat; NEUROMetrix, Inc, Waltham, MA). Validity of the automated nerve conduction testing system was shown by comparing presurgical distal motor latencies (DMLs) against a reference obtained by referral to an electromyography laboratory. The DML was evaluated in 48 patients with CTS. Measurements were obtained within 1 hour of surgery and at 2 weeks, 6 weeks, 3 months, and 6 months after carpal tunnel release. Presurgical and postsurgical DMLs were then compared and correlated with variables and possible predictors of outcome including age, body mass index, gender, and presurgical DMLs. The automated nerve conduction testing system DMLs matched those of reference electromyography/nerve conduction study values with high correlation. Sensitivity of the automated nerve conduction testing system when compared with a standardized CTS case definition was 89%, with a specificity of 95%. A significant correlation was found between the DML before release and the DML 1 hour after release. Moreover, maximal postsurgical DML improvement was highly dependent on the presurgical DML, with no improvement shown for the <4-ms group, mild improvement for the 4-to-6-ms group, and maximal improvement in the >6-ms group. Among the clinical variables of age, gender, and body mass index only age was mildly predictive of postrelease DML changes at 6 months. No other correlations between clinical variables and postsurgical DMLs were significant. In addition the predictive value of age was lost when combined with the presurgical DML in a multivariate analysis. Postsurgical changes in the median nerve DML were highly dependent on the prerelease latency. The sensitivity and specificity of a nerve conduction monitoring system in detecting and aiding in the diagnosis of CTS is useful in the long-term management of patients with CTS and can aid in determining the level of improvement in median nerve function after endoscopic carpal tunnel release.

Acute liver failure caused by hepatitis E virus genotype 3 and 4 has been rarely described. Because of the presence of a short golden therapeutic window in patients with viral acute liver failure from other causes, it is possible that early recognition and treatment might reduce the morbidity and mortality. We performed a systematic review and pooled analysis of acute liver failure caused by hepatitis E virus genotype 3 and 4. Two reviewers appraised studies after searching multiple databases on June 12th, 2017. Appropriate tests were used to compare hepatitis E virus genotype 3 vs 4, suspected vs confirmed genotypes, hepatitis E virus-RNA positive vs negative, and to discern important mortality risk factors. We identified 65 patients, with median age 58 years (range: 3-79), and a male to female ratio of 1.2:1. The median bilirubin, ALT, AST and alkaline phosphatase (expressed by multiplication of the upper limit of normal) levels were 14.8, 45.3, 34.8 and 1.63 respectively. Antihepatitis E virus IgG, antihepatitis E virus IgM and hepatitis E virus-RNA were positive in 84%, 91% and 86% of patients respectively. The median interval from symptoms onset to acute liver failure was 23 days, and 16 patients underwent liver transplantation. Final outcome was reported in 58 patients and mortality was 46%. Age was a predictor of poor prognosis in multivariate analysis. No important differences were found between patients infected with genotype 3 vs 4, patients with confirmed vs suspected genotypes, or patients with positive vs negative RNA. Acute liver failure caused by hepatitis E virus genotype 3 and 4 is rare, similar between genotypes, occurs commonly in middle-aged/elderly patients and has a very high mortality. Age is predictive of poor prognosis in multivariate analysis. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Brain metastases from hepatocellular carcinoma (HCC) are rare, but their incidence is increasing because of developments in recent therapeutic advances. The purpose of this study was to investigate the characteristics of brain metastases from HCC, to evaluate the predictive factors, and to assess the efficacy of gamma knife surgery (GKS). A retrospective study was performed on patients with brain metastases from HCC who were treated at Tokyo Gamma Unit Center from 2005 to 2014. Nineteen patients were identified. The median age at diagnosis of brain metastases was 67.0 years. Fifteen patients were male and four patients were female. Six patients were infected with hepatitis B virus (HBV). Two patients were infected with hepatitis C virus (HCV). Eleven patients were not infected with HBV or HCV. The median interval from the diagnosis of HCC to brain metastases was 32.0 months. The median number of brain metastases was two. The median Karnofsky performance score at first GKS was 70. The median survival time following brain metastases was 21.0 weeks. Six-month and 1-year survival rates were 41.2 and 0%, respectively. One month after GKS, no tumor showed progressive disease. The HBV infection (positive vs. negative) was significantly associated with survival according to univariate analysis (p = 0.002). The patients having brain metastases from HCC had poor prognosis and low performance state. Therefore, GKS is an acceptable option for controlling brain metastases from HCC because GKS is noninvasive remedy and local control is reasonable.

Seventeen patients transplanted with hematopoietic cells to correct severe T lymphocyte immunodeficiency resulting from complete DiGeorge anomaly were identified worldwide, and retrospective data were obtained using a questionnaire-based survey. Patients were treated at a median age of 5 months (range, 2-53 months) between 1995 and 2006. Bone marrow was used in 11 procedures in 9 cases: 6 from matched unrelated donors, 4 from human leukocyte antigen (HLA)-identical siblings, and one haploidentical parent with T-cell depletion. Unmobilized peripheral blood was used in 8 cases: 5 from HLA-identical siblings, one from a matched unrelated donor, one from an HLA-identical parent, and one unrelated matched cord blood. Conditioning was used in 5 patients and graft-versus-host disease prophylaxis in 11 patients. Significant graft-versus-host disease occurred in 9 patients, becoming chronic in 3. Median length of follow-up was 13 months, with transplantation from HLA-matched sibling showing the best results. Median survival among deceased patients (10 patients) was 7 months after transplantation (range, 2-18 months). The overall survival rate was 41%, with a median follow-up of 5.8 years (range, 4-11.5 years). Among survivors, median CD3 and CD4 counts were 806 (range, 644-1224) and 348 (range, 225-782) cells/mm3, respectively, CD4+/CD45RA+ cells remained very low, whereas mitogen responses were normalized.

This study aimed to establish gender-related differences and the percentile curves for total body fat mass percentage (Total FM%), trunk/appendicular fat mass ratio (TrAppFMR), and fat mass ratio as % fat trunk/% fat lower limb (TrLLFMR) in Chinese children and adolescents using dual-energy X-ray absorptiometry (DXA). Children (n = 1541; 764 girls) and adolescents aged 5 to 19 years were recruited from southern China. Total FM% and regional FM were measured by DXA. TrAppFMR values were calculated as trunk FM divided by appendicular FM, and TrLLFMR values were calculated as the ratio between the percentage of trunk FM and the percentage of lower limb FM. Total FM% peaks for boys were at approximately age 11 years and continued to increase for girls throughout adolescence. Median Total FM% at the age of 19 years was 15.53% and 28.06% for boys and girls, respectively. Median TrAppFMR and TrLLFMR increases were 61% and 81% from 5 to 19 years of age in boys compared with those in girls, 31% and 54%. The curves for median TrAppFMR and TrLLFMR in girls were relatively flat, with TrAppFMR and TrLLFMR remaining near 1.0 after 16 years of age, whereas in boys, median TrAppFMR and TrLLFMR increased with age until approximately 19 years. Gender differences in the patterns of proportion and distribution of body fat were found. We present sex-specific percentile curves for Total FM%-age, TrAppFMR-age, and TrLLFMR-age relationships in this population.

OBJECTIVE An anti-angiogenic state has been described in patients with preeclampsia, small for gestational age (SGA) fetuses and fetal death, and changes in the concentration of circulating angiogenic and anti-angiogenic factors can precede the clinical recognition of preeclampsia and small for gestational age by several weeks. Gene deletion studies demonstrate that a selective group of endothelial growth factors are required for vascular development, including members of the vascular endothelial growth factor (VEGF) family, as well as Angiopoietin-1 and Angiopoietin-2, both ligands for the tyrosine kinase endothelial cell receptor Tie-2. These angiogenic factors have been proposed to promote angiogenesis in a coordinated and complementary fashion. Soluble Tie-2 (sTie-2) is the soluble form of the Tie-2 receptor which is detectable in biological fluids. The purpose of this study was to determine whether patients with preeclampsia and mothers who deliver a small for gestational age neonate have changes in the plasma concentrations of sTie-2. STUDY DESIGN This cross-sectional study included patients in the following groups: 1) non-pregnant women (n=40); 2) women with normal pregnancies (n=135); 3) patients with preeclampsia (n=112); and 4) patients who delivered a small for gestational age (SGA) neonate (n=53). Maternal plasma concentrations of sTie-2 were measured by a sensitive immunoassay. Parametric statistics were used for analysis. RESULTS 1) The median maternal plasma concentration of sTie-2 was lower in normal pregnant women than in non-pregnant women [median 16.0 ng/ml (range 5.0–71.6) vs. median 20.7 ng/ml (range 10.8–52.4), respectively; p=0.01)]; 2) Plasma sTie-2 concentrations in normal pregnancy changed significantly as a function of gestational age; 3) Patients with preeclampsia and those who delivered SGA neonates had a lower median maternal plasma concentration of sTie-2 than those with a normal pregnancy [Preeclampsia: median 14.9 ng/ml (range 4.9–67.3); SGA: median 10.9 ng/ml (range 5.1–29.1); Normal pregnancy: median 16.0 ng/ml (range 5.0–71.6); p=0.048 and p<0.001, respectively]; 4) Patients with SGA neonates had a lower median plasma concentration of sTie-2 than that of those with preeclampsia [median 10.9 ng/ml (range 5.1–29.1) vs. median 14.9 ng/ml (range 4.9–67.3), respectively; p<0.001)]; and 5) Patients with early-onset preeclampsia (≤34 weeks) had lower concentrations of sTie-2 than women with late-onset preeclampsia (>34 weeks) [median of delta values: −0.13 ng/ml (range −0.47–0.58) vs. median of delta values: −0.09 ng/ml (range: −0.60–0.58), respectively; p=0.043]. In contrast, there were no significant differences in the maternal plasma sTie-2 concentration between women with severe and mild preeclampsia (p=0.6). CONCLUSION Patients with preeclampsia and those with SGA fetuses have lower median plasma concentrations of soluble Tie-2 than women with normal pregnancies. PMID:18570117

Stereotactic radiosurgery (SRS) is a potentially important option for intracranial ependymoma patients. To analyze the outcomes of intracranial ependymoma patients who underwent SRS as a part of multimodality management. Seven centers participating in the International Gamma Knife Research Foundation identified 89 intracranial ependymoma patients who underwent SRS (113 tumors). The median patient age was 16.3 yr (2.9-80). All patients underwent previous surgical resection and radiation therapy (RT) of their ependymomas and 40 underwent previous chemotherapy. Grade 2 ependymomas were present in 42 patients (52 tumors) and grade 3 ependymomas in 48 patients (61 tumors). The median tumor volume was 2.2 cc (0.03-36.8) and the median margin dose was 15 Gy (9-24). Forty-seven (53%) patients were alive and 42 (47%) patients died at the last follow-up. The overall survival after SRS was 86% at 1 yr, 50% at 3 yr, and 44% at 5 yr. Smaller total tumor volume was associated with longer overall survival (P = .006). Twenty-two patients (grade 2: n = 9, grade 3: n = 13) developed additional recurrent ependymomas in the craniospinal axis. The progression-free survival after SRS was 71% at 1 yr, 56% at 3 yr, and 48% at 5 yr. Adult age, female sex, and smaller tumor volume indicated significantly better progression-free survival. Symptomatic adverse radiation effects were seen in 7 patients (8%). SRS provides another management option for residual or recurrent progressive intracranial ependymoma patients who have failed initial surgery and RT.

Pilot study to assess the effect of augmentative and alternative communication technology to enhance language development in children who are deaf or hard-of-hearing. Five children ages 5-10 years with permanent bilateral hearing loss who were identified with language underperformance participated in an individualized 24-week structured program using the application TouchChat WordPower on iPads ® . Language samples were analyzed for changes in mean length of utterance, vocabulary words and mean turn length. Repeated measures models assessed change over time. The baseline median mean length of utterance was 2.41 (range 1.09-6.63; mean 2.88) and significantly increased over time (p = 0.002) to a median of 3.68 at final visit (range 1.97-6.81; mean 3.62). At baseline, the median total number of words spoken per language sample was 251 (range 101-458), with 100 (range 36-100) different words spoken. Total words and different words significantly increased over time (β = 26.8 (7.1), p = 0.001 for total words; β = 8.0 (2.7), p = 0.008 for different words). Mean turn length values also slightly increased over time. Using augmentative and alternative communication technology on iPads ® shows promise in supporting rapid language growth among elementary school-age children who are deaf or hard-of-hearing with language underperformance.

Circulatory failure due to acute arterial hypertension in the neonatal period is rare. This study was undertaken to assess the clinical and echocardiographic manifestations of circulatory failure resulting from acute neonatal hypertensive crisis. Neonatal and cardiology databases from 2007 to 2010 were reviewed. An established diagnosis of circulatory failure due to neonatal hypertension before the age of 14 days was required for inclusion. Six patients were identified. Five patients presented with circulatory failure due to an acute hypertensive crisis. The median age at presentation was 8.5 days (range: 6.0-11.0) with a median body weight of 3.58 kg (range: 0.86-4.70). Echocardiography demonstrated mild left ventricular dysfunction [median shortening fraction (SF) 25%, range 10-30] and mild aortic regurgitation in 83% (5/6) of patients. One patient with left ventricular dysfunction (SF = 17%) had a large apical thrombus. Two patients were hypotensive, and hypertension only became evident after restoration of cardiac output. Administration of intravenous milrinone was successful, with rapid improvement of the clinical condition. Left ventricular function normalised in all survivors. Early neonatal circulatory collapse due to arterial hypertension is a rare but potentially life-threatening condition. At presentation, hypotension, especially in the presence of a dysfunctional left ventricle, does not exclude a hypertensive crisis being the cause of circulatory failure. The echocardiographic presence of mild aortic regurgitation combined with left ventricular hypocontractility in a structurally normal heart should alert the physician to the presence of underlying hypertension.

The objective of this paper is to measure the clinical course (months) in young athletes with persistent fatigue and to identify any covariates affecting the duration of recovery. This was a prospective longitudinal study of 68 athletes; 87% were elite (42 males, 26 females), aged 20.5±3.74 years (SD), who presented with the symptom of persistent fatigue. The collective duration to full clinical recovery was estimated using Kaplan-Meier product-limit curves, and covariates associated with prolonging recovery were identified from Cox proportional hazard models. The median recovery was 5 months (range 1-60 months). The range of presenting symptom duration was 0.5-36 months. The covariates identified were an increased duration of presenting symptoms [hazard ratio (HR), 1.06; 95% confidence interval (CI), 1.02-1.12; P=0.005] and the response of serum cortisol concentration to a standard exercise challenge (HR, 1.92; 95% CI, 1.09-3.38; P=0.03). Delay in recovery was not associated with categories of fatigue that included medical, training-related diagnoses, or other causes. In conclusion, the fatigued athlete represents a significant clinical problem with a median recovery of 5 months, whose collective clinical course to recovery can be estimated by Kaplan-Meier curves and appears to be a continuum. © 2009 John Wiley & Sons A/S.

The purpose of this study was to see how coronary magnetic resonance angiography (CMRA) compared to echocardiography for the detection of coronary artery origins and to compare CMRA measurements for coronary dimensions in children with published echocardiographic reference values. Enrolled patients underwent dual cardiac phase CMRA and echocardiography under the same anesthetic. Echocardiographic measurements of the right coronary artery (RCA), left anterior descending (LAD) and left main (LM) were made. CMRA dimensions were assessed manually at the same points as the echocardiographic measurements. The number of proximal LAD branches imaged was also recorded in order to give an estimate of distal coronary tree visualization. Fifty patients (24 boys, mean age 4.0 years (range 18 days to 18 years)) underwent dual-phase CMRA. Coronary origins were identified in 47/50 cases for CMRA (remaining 3 were infants aged 3, 9 and 11 months). In comparison, origins were identified in 41/50 cases for echo (remaining were all older children). CMRA performed better than echocardiography in terms of distal visualization of the coronary tree (median 1 LAD branch vs. median 0; p = 0.001). Bland-Altman plots show poor agreement between echocardiography and CMRA for coronary measurements. CMRA measurements did vary according to cardiac phase (systolic mean 1.90, s.d. 0.05 mm vs. diastolic mean 1.84, s.d. 0.05 mm; p = 0.002). Dual-phase CMRA has an excellent (94 %) success rate for the detection of coronary origins in children. Newborn infants remain challenging and echocardiography remains the accepted imaging modality for this age group. Echocardiographic reference ranges are not applicable to CMRA measurements as agreement was poor between modalities. Future coronary reference values, using any imaging modality, should quote the phase in which it was measured.

Point-of-sale (POS) advertising at retail stores is one of the key marketing avenues used by the tobacco industry. The United States Surgeon General urges actions to eliminate POS tobacco advertisements because of their influence on youth smoking. Many youth empowerment programs are implemented to address tobacco industry marketing influences, including POS tobacco advertisements. While youth are asked to take on such collective action, little is known regarding their perceptions and understanding of tobacco industry marketing influences and related advocacy activities. This mixed methods study examined Oklahoma's tobacco control youth empowerment program members' perceptions of tobacco industry marketing influences. Four focus groups were held with active program members from rural and urban areas. Overall, the focus group participants viewed the program as purposeful, as an avenue to help others, and as a way to make a difference. Specifically, the older participants (median age = 18 years) identified tobacco industry marketing influences such as POS, movies, and magazine advertisements and reported participating in activities that counter POS tobacco advertisements at retail stores. Likewise younger participants (median age = 16 years), identified similar tobacco industry marketing influences, but also included tobacco use by friends and family as tobacco industry marketing influences. Moreover, the younger participants did not report engaging in activities that addressed POS tobacco advertisements. The study results suggest that the empowerment program should tailor its programming, training, materials, and activities with input from youth of various ages. Thoughtfully developed messages and specific activities can truly empower youth and maximize their contribution as change agents who address POS or other initiatives at the retail environments to prevent chronic diseases.

To identify novel risk markers for incident heart failure using proteomic profiling of 80 proteins previously associated with cardiovascular pathology. Proteomic profiling (proximity extension assay) was performed in two community-based prospective cohorts of elderly individuals without heart failure at baseline: the Prospective Investigation of the Vasculature in Uppsala Seniors [PIVUS, n = 901, median age 70.2 (interquartile range 70.0-70.3) years, 80 events]; and the Uppsala Longitudinal Study of Adult Men [ULSAM, n = 685, median age 77.8 (interquartile range 76.9-78.1) years, 90 events]. Twenty-nine proteins were associated with incident heart failure in the discovery cohort PIVUS after adjustment for age and sex, and correction for multiple testing. Eighteen associations replicated in ULSAM. In pooled analysis of both cohorts, higher levels of nine proteins were associated with incident heart failure after adjustment for established risk factors: growth differentiation factor 15 (GDF-15), T-cell immunoglobulin and mucin domain 1 (TIM-1), tumour necrosis factor-related apoptosis-inducing ligand receptor 2 (TRAIL-R2), spondin-1 (SPON1), matrix metalloproteinase-12 (MMP-12), follistatin (FS), urokinase-type plasminogen activator surface receptor (U-PAR), osteoprotegerin (OPG), and suppression of tumorigenicity 2 (ST2). Of these, GDF-15, U-PAR, MMP-12, TRAIL-R2, SPON1 and FS were associated with worsened echocardiographic left ventricular systolic function at baseline, while only TIM-1 was positively associated with worsened diastolic function (P < 0.02 for all). Proteomic profiling identified several novel associations between proteins involved in apoptosis, inflammation, matrix remodelling, and fibrinolysis with incident heart failure in elderly individuals. Our results encourage additional studies investigating the underlying mechanisms and the clinical utility of our findings. © 2017 The Authors.

To assess health-related quality of life (HRQoL) parameters in patients who received radical cystectomy (RC) with ileal orthotopic neobladder (IONB) reconstruction and to identify clinic-pathologic predictors of HRQoL. From January 2010 to December 2013, a multicenter, retrospective on 174 RC-IONB patients was carried out. All patients completed the following questionnaires: the European Organization for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the IONB-Patient Reported Outcome (IONB-PRO). Univariate and multivariate analyses were computed to identify clinic-pathologic predictors of HRQoL. Median age was 66 years (range, 31-83), and 91.4% of patients were men. Median follow-up period was 37 months (range, 3-247). The EORTC QLQ-C30 revealed that age >65 years, absence of urinary incontinence, and absence of peripheral vascular disease were independent predictors of deteriorated body image. A follow-up > 36 months and the presence of urinary incontinence were independent predictors of worsened urinary symptoms, whereas the absence of urinary incontinence was an independent predictor of a worsened body image according to EORTC QLQ-BLM30 results. A follow-up >36 months and the absence of urinary incontinence were independent predictors of better functioning in terms of relational life, emotional life, and fatigue as revealed by the IONB-PRO. Age, presence of urinary incontinence, length of follow-up, and comorbidity status may influence postoperative HRQoL and should all be taken into account when counseling RC-IONB patients.

To determine success rates, predictors of recurrence, and recurrence management of patients treated for short anterior urethral strictures by direct vision internal urethrotomy (DVIU). We identified 128 patients who underwent DVIU of the anterior urethra between December 2009 and March 2016. Follow-up was conducted by telephone interviews. Success rates were assessed by Kaplan-Meier estimators. Predictors of stricture recurrence and different further therapy strategies were identified by uni- and multivariable Cox regression analyses. The mean age was 63.8 years (standard deviation: 16.3) and the overall success rate was 51.6% (N = 66) at a median follow-up of 16 months (interquartile range: 6-43). Median time to stricture recurrence was six months (interquartile range: 2-12). In uni- and multivariable analyses, only repeat DVIU (hazard ratio [HR] = 1.87, 95% confidence interval (CI) = 1.13-3.11, P= .015; and HR=1.78, 95% CI = 1.05-3.03, P = .032, respectively) was a risk factor for recurrence. Of 62 patients with recurrence, 35.5% underwent urethroplasty, 29% underwent further endoscopic treatment, and 33.9% did not undergo further interventional therapy. Age (HR = 1.05, 95% CI = 1.01-1.09, P = .019) and diabetes (HR = 2.90, 95% CI = 1.02-8.26, P = .047) were predictors of no further interventional therapy. DVIU seems justifiable in short urethral strictures as a primary treatment. Prior DVIU was a risk factor for recurrence. In case of recurrence, about one-third of the patients did not undergo any further therapy. Higher age and diabetes predicted the denial of any further treatment. Copyright © 2017 Elsevier Inc.

Very preterm infants can be treated with nasal continuous positive airway pressure (CPAP) from birth, but some fail. A rapid test, such as the stable microbubble test (SMT) on gastric aspirate, may identify those who can be managed successfully using CPAP. To determine if SMT can identify soon after birth, very preterm infants who may be successfully managed on CPAP alone. Stable microbubbles (diameter <15 µm) were counted in gastric aspirates taken <1 h of age from infants <30 weeks' gestation, who received CPAP from birth. Infants failed CPAP if intubated at <72 h of age. Clinicians were masked to SMT results. A receiver operating characteristic curve was generated to determine the relationship between number of microbubbles/mm(2) and subsequent intubation. 68 infants of mean (SD) 28.1 (1.4) weeks' gestation received CPAP in the delivery room at a median (interquartile range) pressure 7 (6-8) cmH2O and FiO2 0.25 (0.21-0.3). Gastric aspirates were taken at a median (interquartile range) age of 0.5 (0.3-0.6) hours. The best cut-off point for predicting CPAP success or failure was a SMT count of 8 microbubbles/mm(2). The area under the receiver operating characteristic curve was 0.8 (95% CI 0.7-0.9). A SMT count ≥8 microbubbles/mm(2) had a sensitivity of 53%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 60% for predicting CPAP success. Infants treated with CPAP from birth, who had SMT counts ≥8 microbubbles/mm(2) on their gastric aspirate, did not fail CPAP. Copyright © 2013 S. Karger AG, Basel.

Localized scleroderma also called morphea is a skin disorder of undetermined cause. The widely recognized Mayo Clinic Classification identifies 5 main morphea types: plaque, generalized, bullous, linear and deep. Whether each of these distinct types has a particular clinical course or is associated with some patient-related features is still unclear. We report here a retrospective series of patients with localized scleroderma with an attempt to identify features related to the type of lesion involved. The medical records of all patients with a diagnosis of localized scleroderma were reviewed by skilled practitioners. Lesions were classified according to the Mayo Clinic Classification. The relationship between each lesion type and various clinical features was tested by non-parametrical methods. The sample of 52 patients included 43 females and 9 males. Median age at onset was 30 y (range 1-76). Frequencies of patients according to morphea types were: plaque morphea 41 (78.8%) (including morphea en plaque 30 (57.7%) and atrophoderma of Pasini-Pierini 11 (21.1%)), linear scleroderma 14 (26.9%). Nine patients (17.3%) had both types of localized scleroderma. Median age at onset was lower in patients with linear scleroderma (8 y (range 3-44)) than in others (36 y (range 1-77)) (p=0.0003). Head involvement was more common in patients with linear scleroderma (37.5%) than in other subtypes (11.1%) (p=0.05). Atrophoderma of Pasini-Pierini was never located at the head. Systemic symptoms, antinuclear antibodies and the rheumatic factor were not associated with localized scleroderma types or subtypes. These results suggest that morphea types, in adults are not associated with distinct patient features except for age at disease onset (lower) and the localization on the head (more frequent), in patients with lesions of the linear type.

BACKGROUND: Serologic tests for HIV infection in infants less than 18 months do not differentiate exposure and infection since maternally acquired IgG antibodies may be detected in infants. Thus, the gold standard for diagnosis of HIV-1 infection in infants under the age of 2 years is DNA or reverse transcriptase polymerase chain reaction. There is an urgent need to evaluate alternative and cost effective laboratory methods for early diagnosis of infant HIV-1 infection as well as identifying infected infants who may benefit from cotrimoxazole prophylaxis and/or initiation of highly active antiretroviral therapy. METHODS: Whole blood was collected in EDTA from 137 infants aged 0 to 18 months. DNA polymerase chain reaction was used as the reference standard for diagnosis of HIV-1 infection. T-cell subset profiles were determined by flow cytometry. RESULTS: Seventy-six infants were DNA PCR positive while 61 were negative. The median CD4 counts of PCR negative infants were significantly higher than those of the PCR positive infants, p < 0.001. The median CD4/CD8 ratio and the %CD4 of the PCR positive infants were both significantly lower than those of the negative infants, p < 0.001. The CD4/CD8 ratio had a >98% sensitivity for diagnosis of HIV-1 infection and a specificity of >98%. CONCLUSION: The CD4/CD8 ratio appears useful in identifying HIV-infected infants. The development of lower cost and more robust flow cytometric methods that provide both CD4/CD8 ratio and %CD4 may be cost-effective for HIV-1 diagnosis and identification of infants for cotrimoxazole prophylaxis and/or highly active antiretroviral therapy.

Parasagittal meningiomas arise from the arachnoid cells of the angle formed between the superior sagittal sinus (SSS) and the brain convexity. In this retrospective study, we focused on factors that predict early recurrence and recurrence times. We reviewed 125 patients with parasagittal meningiomas operated from 1985 to 2014. We studied the following variables: age, sex, location, laterality, histology, surgeons, invasion of the SSS, Simpson removal grade, follow-up time, angiography, embolization, radiotherapy, recurrence and recurrence time, reoperation, neurologic deficit, degree of dependency, and patient status at the end of follow-up. Patients ranged in age from 26 to 81 years (mean 57.86 years; median 60 years). There were 44 men (35.2%) and 81 women (64.8%). There were 57 patients with neurologic deficits (45.2%). The most common presenting symptom was motor deficit. World Health Organization grade I tumors were identified in 104 patients (84.6%), and the majority were the meningothelial type. Recurrence was detected in 34 cases. Time of recurrence was 9 to 336 months (mean: 84.4 months; median: 79.5 months). Male sex was identified as an independent risk for recurrence with relative risk 2.7 (95% confidence interval 1.21-6.15), P = 0.014. Kaplan-Meier curves for recurrence had statistically significant differences depending on sex, age, histologic type, and World Health Organization histologic grade. A binary logistic regression was made with the Hosmer-Lemeshow test with P > 0.05; sex, tumor size, and histologic type were used in this model. Male sex is an independent risk factor for recurrence that, associated with other factors such tumor size and histologic type, explains 74.5% of all cases in a binary regression model.

Descriptive study. To determine the presence of median and ulnar neuropathies in both upper extremities of university guitarists. Peripheral nerve entrapment syndromes of the upper extremities are well documented in musicians. Guitarists and plucked-string musicians are at risk for entrapment neuropathies in the upper extremities and are prone to mild neurologic deficits. Twenty-four volunteer male and female guitarists (age range, 18-26 years) were recruited from the Belmont University School of Music and the Vanderbilt University Blair School of Music. Individuals were excluded if they were pregnant or had a history of recent upper extremity or neck injury. Subjects completed a history form, were interviewed, and underwent a physical examination. Nerve conduction status of the median and ulnar nerves of both upper extremities was obtained by performing motor, sensory, and F-wave (central) nerve conduction studies. Descriptive statistics of the nerve conduction study variables were computed using Microsoft Excel. Six subjects had positive findings on provocative testing of the median and ulnar nerves. Otherwise, these guitarists had normal upper extremity neural and musculoskeletal function based on the history and physical examinations. When comparing the subjects' nerve conduction study values with a chart of normal nerve conduction studies values, 2 subjects had prolonged distal motor latencies (DMLs) of the left median nerve of 4.3 and 4.7 milliseconds (normal, < 4.2 milliseconds). Prolonged DMLs are compatible with median neuropathy at or distal to the wrist. Otherwise, all electrophysiological variables were within normal limits for motor, sensory, and F-wave (central) values. However, comparison studies of median and ulnar motor latencies in the same hand demonstrated prolonged differences of greater than 1.0 milliseconds that affected the median nerve in 2 additional subjects, and identified contralateral limb involvement in a subject with a prolonged distal latency. The other 20 subjects demonstrated normal comparison studies of the median and ulnar nerves in both upper extremities. In this descriptive study of a population of 24 university guitarists, 4 musicians (17%) were found to have electrophysiologic evidence of median neuropathy at or distal to the wrist or carpal tunnel syndrome. Ulnar nerve electrophysiological function was within normal limits for all subjects examined.

A multi-country study of intussusception in children under 2 years of age in Latin America: analysis of prospective surveillance data

PubMed Central

2013-01-01

Background Intussusception (IS) is a form of acute intestinal obstruction that occurs mainly in infants and is usually of unknown cause. An association between IS and the first licensed rotavirus vaccine, a reassortant-tetravalent, rhesus-based rotavirus vaccine (RRV-TV), led to the withdrawal of the vaccine. New rotavirus vaccines have now been developed and extensively studied for their potential association with IS. This study aimed to describe the epidemiology and to estimate the incidence of IS in Latin American infants prior to new vaccine introduction. Methods Children under 2 years of age representing potential IS cases were enrolled in 16 centers in 11 Latin American countries from January 2003 to May 2005. IS cases were classified as definite, probable, possible or suspected as stated on the Brighton Collaboration Working Group guidelines. Results From 517 potential cases identified, 476 (92%) cases were classified as definite, 21 probable, 10 possible and 10 suspected for intussusception. Among the 476 definite IS cases, the median age at presentation was 6.4 months with 89% of cases aged <1 year. The male to female ratio was 1.5:1. The incidence of definite IS per 100,000 subject-years ranged from 1.9 in Brazil to 62.4 in Argentina for children <2 years of age, and from 3.8 in Brazil to 105.3 in Argentina for children aged <1 year. Median hospital stay was 4 days with a high prevalence of surgery as the primary treatment (65%). Most cases (88%) made a complete recovery, but 13 (3%) died. No clear seasonal pattern of IS cases emerged. Conclusions This study describes the epidemiology and estimates the incidence of IS in Latin American infants prior to the introduction of new rotavirus vaccines. The incidence of IS was found to vary between different countries, as observed in previous studies. Trial registration Clinical study identifier 999910/204 (SERO-EPI-IS-204) PMID:23710610

Advanced glycation endproducts (AGEs) are the products of non-enzymatic glycation and oxidation of proteins and lipids. Low-turnover tissues such as articular cartilage seem to be susceptible to the accumulation of AGEs, which might lead to cartilage degradation. Recently, a non-invasive method for measuring skin AGE accumulation was developed by using the Autofluorescence Reader (AFR). To examine the usefulness of measuring skin AGE in patients with bone and joint diseases, we examined autofluorescence (AF) levels in skin of patients with osteoarthritis (OA), rheumatoid arthritis (RA), and dialysis-related spondyloarthropathy (DRSA). Ninety-three patients with RA, 24 patients with OA, and 29 patients with DRSA were examined, and 43 healthy volunteers were used as controls. Skin AF was assessed on the lower arm with the AGE-Reader. Mean AF was significantly higher in the patients with RA (median 2.13 and range 1.25-2.94) or with DRSA (median 2.21 and range 1.29-3.88) than in the patients with OA (median 1.63 and range 1.07-2.31) or in the controls (median 1.74 and range 1.10-2.46). There was no significant difference between OA and the controls, or between RA and DRSA. These findings suggest that differences of AGE accumulation in the skin might reflect the different pathologies of these diseases.

To define the clinical features and outcomes of neonatal listeriosis, and identify the maternal risk factors to seek scope for improvement. Neonatal listeriosis was identified prospectively from a United Kingdom neonatal infection surveillance network (neonIN) between 2004 and 2014. The participating neonatal units completed a study-specific proforma. The incidence of neonatal listeriosis was 3.4 per 100,000 live births. Of the 21 cases identified, 19 were confirmed with a median gestational age of 33 weeks and a median birth weight of 1960 g. The majority had clinical features (95%, 18/19), presented within the first 24 h (95%, 18/19), and received penicillin empirically (94%, 18/19). The neonatal case-fatality rate was 21% (24% if probable cases were included). A proportion of mothers were investigated (60%, 12/18) and diagnosed with listeriosis (58%, 7/12); 32% (6/19) were treated with antibiotics but only 33% (6/12) included penicillin. Despite its rarity and the prompt and appropriate use of antibiotics neonatal listeriosis has a high case-fatality rate. There is room for improvement in the adherence to the empiric antibiotic choice for puerperal sepsis, according to the national guidelines as this, would target listeriosis. Strategies should be in place to prevent pregnancy-associated listeriosis in higher risk population. Copyright © 2016 The British Infection Association. All rights reserved.

To report long-term local control in patients with adenoid cystic cancer (ACC) of the head and neck managed by surgery and identify factors predictive for local failure. Single-institution retrospective cohort study. Eighty-seven patients who had surgery for ACC between 1985 and 2009 were identified. Patient, tumor, and treatment characteristics were recorded. Local recurrence-free survival (LRFS) was recorded by the Kaplan-Meier method. Predictors of local control were identified. The median age was 54 years. Seventy-two (83%) patients had perineural invasion, 61 (70%) had close/positive margins, and 58 (67%) had pT 1T2. Fifty-nine (68%) patients had postoperative radiation therapy (PORT). With a median follow-up of 85 months, the 10-year LRFS was 78.7%. There were 14 local recurrences. On multivariable analysis, pathological tumor (T)3T4 stage and no PORT were independent predictors for local failure. Patients with no PORT had a 13-fold increased risk of local failure compared to patients treated with PORT (P = 0.003) after adjusting for stage. After adjusting for T stage, patients who do not get PORT are more likely to have local recurrence. 4.

Abstract Background: Medication utilization and costs increased over the last decade, but the effects of race/ethnicity have never been well studied in longitudinal data. We analyzed reports of prescription medication use to (1) identify trajectories of use and (2) determine predictors associated with a large increase in use. Specifically, variations in medication use by race/ethnicity were examined. Methods: We analyzed the Study of Women's Health Across the Nation cohort with a median of 14 years of follow-up. Group-based trajectory models helped distinguish women with a low use of medications versus those with heavy use. Logistic regression was used to estimate the odds ratio (OR) for each racial/ethnic group associated with heavy use, controlling for potential baseline confounders. Results: The 2,798 women sampled had a mean age of 46 years at baseline and the median number of medications at baseline was 2, increasing to 4 over the follow-up period. Trajectory models identified that 16% of participants demonstrated heavy use of medications, from a median of 5 at baseline to 10 medications at final follow-up. Regression models controlling for age, obesity, number of comorbid conditions, and pain found that Hispanic (OR = 0.085, 95% confidence interval [CI]: 0.037–0.20), Chinese (OR = 0.32, 95% CI: 0.16–0.63), Japanese (OR = 0.33, 95% CI: 0.17–0.64), and Black (OR = 0.79, 95% CI: 0.57–1.11) women had lower odds for heavy use compared with White women. Conclusions: Longitudinal medication use among women in Study of Women's Health Across the Nation (SWAN) differed by race/ethnicity with non-White women having a lower odds of heavy use.

The purpose of the study was to evaluate the prostate serum antigen (PSA) response, local control, progression-free survival (PFS), and toxicity of stereotactic body radiotherapy (SBRT) for lymph node (LN) oligorecurrent prostate cancer. Between May 2012 and October 2015, 124 lesions were treated in 94 patients with a median dose of 24 Gy in 3 fractions. Seventy patients were treated for a single lesion and 25 for > 1 lesion. In 34 patients androgen deprivation (AD) was combined with SBRT. We evaluated biochemical response according to PSA level every 3 months after SBRT: a 3-month PSA decrease from pre-SBRT PSA of more than 10% identified responder patients. In case of PSA level increase, imaging was performed to evaluate clinical progression. Toxicity was assessed every 6 to 9 months after SBRT. Median follow-up was 18.5 months. In 13 patients (14%) Grade 1 to 2 toxicity was reported without any Grade 3 to 4 toxicity. Biochemical response, stabilization, and progression were observed in 64 (68%), 10 (11%), and 20 (21%) of 94 evaluable patients. Clinical progression was observed in 31 patients (33%) after a median time of 8.1 months. In-field progression occurred in 12 lesions (9.7%). Two-year local control and PFS rates were 84% and 30%, respectively. Age older than 75 years correlated with better biochemical response rate. Age older than 75 years, concomitant AD administered up to 12 months, and pelvic LN involvement correlated with longer PFS. SBRT is safe and offers good in-field control. At 2 years after SBRT, 1 of 3 patients is progression-free. Further investigation is warranted to identify patients who benefit most from SBRT and to define the optimal combination with AD.

MDMB-CHMICA is a synthetic cannabinoid receptor agonist which has caused concern due to its presence in cases of adverse reaction and death. 43 cases of suspected synthetic cannabinoid ingestion were identified from patients presenting at an Emergency Department and from post-mortem casework. These were subjected to liquid-liquid extraction using tertiary-butyl methyl ether and quantitatively analysed by Electrospray Ionisation Liquid Chromatography-tandem Mass Spectrometry. For positive samples, case and clinical details were sought and interrogated. 11 samples were found positive for MDMB-CHMICA. Concentrations found ranged from <1 to 22 ng/mL (mean: 6 ng/mL, median: 3 ng/mL). The age range was 15-44 years (mean: 26 years, median: 21 years), with the majority (82%) of positive results found in males. Clinical presentations included hypothermia, hypoglycaemia, syncope, recurrent vomiting, altered mental state and serotonin toxicity, with corresponding concentrations of MDMB-CHMICA as low as <1 ng/mL. Duration of hospitalisation ranged from 3 to 24 h (mean: 12 h, median: 8 h). The concentration range presented in this case series is indicative of MDMB-CHMICA having a high potency, as is known to be the case for other synthetic cannabinoid receptor agonists. The age range and gender representation were consistent with that reported for users of other drugs of this type. The clinical presentations observed were typical of synthetic cannabinoid receptor agonists and show the difficulties in identifying reactions potentially associated with drugs of this type. The range of MDMB-CHMICA concentrations in Emergency Department presentations (n = 9) and post-mortem cases (n = 2) was reported. No correlation between the concentration of this drug and clinical presentation or cause of death was reported in this sample. However, the potential for harm associated with low concentrations of MDMB-CHMICA and the symptoms of toxicity being non-specific were highlighted.

This study aimed to assess the impact of esophageal stenting on postoperative complications and survival in patients with obstructing esophageal and gastroesophageal junction (GEJ) cancer. All patients treated without neoadjuvant therapy that had an R0-resection performed for esophageal and GEJ cancer between January 2003 and December 2010 were identified from a prospectively maintained database. Data on stenting, postoperative mortality, morbidity, recurrence-free survival, complications, and length of hospital stay were collected. Kaplan-Meier plots for survival and recurrence-free survival curves were constructed for R0 resected patients. Data were compared between the stent and no-stent group by nonparametric tests. Two hundred seventy three consecutive R0 resected patients with esophageal or GEJ cancer were identified. Of these patients, 63 had a stent as a bridge to surgery. The male/female ratio was 2.64 (198/75) with a median age in the stent group (SG) of 65.1 versus 64.3 in the no stent group (NSG). Patients were comparable with respect to gender, age, smoking, TNM-classification, oncological treatment, hospital stay, tumor location, and histology. The median survival in the SG was 11.6 months compared with 21.3 months for patients treated without a bridging stent (P < 0.001). There were no statistically significant differences in 30-day mortality between the two groups, but NSG patients exhibited a significantly better two-year survival (P = 0.017). The median recurrence-free survival was 9.1 months for the SG compared with 15.2 months for the NSG. The use of a stent as a bridging procedure to surgery in patients treated without neaoadjuvant therapy for an esophageal or GEJ cancer that later underwent R0 resection decreased the two year survival and the recurrence-free survival. © 2016 International Society for Diseases of the Esophagus.

Most Western health systems remain single illness orientated despite the growing prevalence of multi-morbidity. Identifying how much time people with multiple chronic conditions spend managing their health will help policy makers and health service providers make decisions about areas of patient need for support. This article presents findings from an Australian study concerning the time spent on health related activity by older adults (aged 50 years and over), most of whom had multiple chronic conditions. A recall questionnaire was developed, piloted, and adjusted. Sampling was undertaken through three bodies; the Lung Foundation Australia (COPD sub-sample), National Diabetes Services Scheme (Diabetes sub-sample) and National Seniors Australia (Seniors sub-sample). Questionnaires were mailed out during 2011 to 10,600 older adults living in Australia. 2540 survey responses were received and analysed. Descriptive analyses were completed to obtain median values for the hours spent on each activity per month. The mean number of chronic conditions was 3.7 in the COPD sub-sample, 3.4 in the Diabetes sub-sample and 2.0 in the NSA sub-sample. The study identified a clear trend of increased time use associated with increased number of chronic conditions. Median monthly time use was 5-16 hours per month overall for our three sub-samples. For respondents in the top decile with five or more chronic conditions the median time use was equivalent to two to three hours per day, and if exercise is included in the calculations, respondents spent from between five and eight hours per day: an amount similar to full-time work. Multi-morbidity imposes considerable time burdens on patients. Ageing is associated with increasing rates of multi-morbidity. Many older adults are facing high demands on their time to manage their health in the face of decreasing energy and mobility. Their time use must be considered in health service delivery and health system reform.

Sentinel lymph node biopsy (SLNB) is recommended for patients with intermediate-thickness melanoma, but the use of SLNB for patients with thick melanoma is debated. This report presents a single-institution study investigating factors predictive of sentinel lymph node (SLN) metastasis and outcome for thick-melanoma patients . A retrospective review of a single-institution database from 1997 to 2012 identified 147 patients with thick primary cutaneous melanoma (≥4 mm) who had an SLNB. Clinicopathologic characteristics were correlated with nodal status and outcome. The median age of the patients was 67 years, and 61.9 % of the patients were men. The median tumor thickness was 5.5 mm, and 54 patients (36.7 %) had a positive SLN. Multivariable analysis showed that only tumor thickness significantly predicted SLN metastasis (odds ratio 1.14; 95 % confidence interval (CI) 1.02-1.28; P = 0.02). The overall median follow-up period was 34.6 months. Overall survival (OS) and melanoma-specific survival (MSS) were significantly worse for the positive versus negative-SLN patients. Multivariable analysis showed that age [hazard ratio (HR) 1.04; 95 % CI 1.01-1.07; P = 0.02] and SLN status (HR 2.24; 95 % CI 1.03-4.88; P = 0.04) significantly predicted OS, whereas only SLN status (HR 3.85; 95 % CI 2.13-6.97; P < 0.01) significantly predicted MSS. Tumor thickness predicts SLN status in thick melanomas. Furthermore, SLN status is prognostic for OS and MSS in thick-melanoma patients, with positive-SLN patients having significantly worse OS and MSS. These findings show that SLNB should be recommended for thick-melanoma patients, particularly because detection of SLN metastasis can identify patients for potential systemic therapy and treatment of nodal disease at a microscopic stage.

The purpose of this study was to examine how well two commonly used age-based prediction equations for maximal heart rate (HRmax ) estimate the actual HRmax measured in Black and White adults from the HERITAGE Family Study. A total of 762 sedentary subjects (39% Black, 57% Females) from HERITAGE were included. HRmax was measured during maximal exercise tests using cycle ergometers. Age-based HRmax was predicted using the Fox (220-age) and Tanaka (208 - 0.7 × age) formulas. The standard error of estimate (SEE) of predicted HRmax was 12.4 and 11.4 bpm for the Fox and Tanaka formulas, respectively, indicating a wide-spread of measured-HRmax values are compared to their age-predicted values. The SEE (shown as Fox/Tanaka) was higher in Blacks (14.4/13.1 bpm) and Males (12.6/11.7 bpm) compared to Whites (11.0/10.2 bpm) and Females (12.3/11.2 bpm) for both formulas. The SEE was higher in subjects above the BMI median (12.8/11.9 bpm) and below the fitness median (13.4/12.4 bpm) when compared to those below the BMI median (12.2/11.0 bpm) and above the fitness median (11.4/10.3) for both formulas. Our findings show that based on the SEE, the prevailing age-based estimated HRmax equations do not precisely predict an individual's measured-HRmax . Copyright © 2013 Wiley Periodicals, Inc.

Antipsychotic use among young children has grown rapidly despite a lack of approval by the U.S. Food and Drug Administration (FDA) for broad use in this age group. Characteristics of physicians who prescribed antipsychotics to young children were identified, and prescribing patterns involving young children and adults were compared. Physician-level prescribing data from IMS Health's Xponent database were linked with American Medical Association Masterfile data and analyzed. The sample included all U.S. psychiatrists and a random sample of 5% of family medicine physicians who wrote at least ten antipsychotic prescriptions per year from 2008 to 2011 (N=31,713). Logistic and hierarchical binomial regression models were estimated to examine physician prescribing for children ages zero to nine, and the types and numbers of ingredients used for children versus adults ages 20 to 64 were compared. Among antipsychotic prescribers, 42.2% had written at least one antipsychotic prescription for young children. Such prescribing was more likely among physicians age ≤39 versus ≥60 (odds ratio [OR]=1.70) and physicians in rural versus nonrural areas (OR=1.11) and was less likely among males (OR=.93) and graduates of a top-25 versus a lower-ranked U.S. medical school (OR=.87). Among physicians who prescribed antipsychotics to young children and adults, 75.0% of prescriptions for children and 35.7% of those for adults were for drugs with an FDA-approved indication for that age. Fewer antipsychotic agents were prescribed for young children (median=2) versus adults (median=7). Prescribing antipsychotics for young children was relatively common, but prescribing patterns differed between young children and adults.

Young adult survivors of childhood cancer have an increased risk for treatment-related morbidity and mortality. In this study, the authors assessed how treatment for childhood cancer affects older-adult health and health practices. One hundred seven adults treated for childhood cancer between 1947 and 1968, known to have survived past age 50 years, were identified from a single-institution cohort established in 1975. Updated vital status on eligible cases was obtained from public records. Survivors and a control group of their age-matched siblings and cousins completed a mailed survey to assess physical and social function, healthcare practices, and the prevalence of common adult illnesses. Of the 107 survivors known to be alive at age 50 years, 16 were deceased at follow-up; 7 deaths could be associated with prior treatment (second malignancy in radiation field [3], small bowel obstruction after abdominal radiation [2], and cardiac disease after chest irradiation [2]). The 55 survivors (median age, 56 years; range, 51-71 years), and 32 family controls (median age, 58 years; range, 48-70 years), reported similar health practices, health-related quality of life, and social function. However, survivors reported more frequent visits to healthcare providers (P < .05), more physical impairments (P < .05), fatigue (P = .02), hypertension (P = .001), and coronary artery disease (P = .01). An increased risk of hypertension was associated with nephrectomy during childhood (odds ratio, 18.9; 95% confidence interval, 3.0-118.8). The oldest adult survivors of childhood cancer continue to be at risk for treatment-related complications that potentially decrease their life expectancy and compromise their quality of life.

To identify geographic variability in the imaging of infants with congenital hydronephrosis at initial pediatric urologic evaluation. We performed a retrospective review of infants aged ≤ 12 months with congenital hydronephrosis seen as new patients from October 2010 to September 2011 at 3 regionally diverse pediatric urology practices: University of Virginia Hospital, Rady Children's Hospital, and Children's Hospital Colorado. Primary outcomes measured were the type and number of tests ordered at initial evaluation. Independent variables collected included the following: patient age, location, and initial ultrasound findings. Ultrasound findings were manually extracted from the attending pediatric urologist's clinic note. All other data were automatically extracted from the electronic medical record. Proportions were analyzed using Pearson's goodness of fit and Fisher exact tests. Medians were compared using the Kruskal-Wallis test. Two hundred forty-one patients met the study criteria. Median patient age was 2 months and did not differ across sites. Most patients (64.7%) had Society for Fetal Urology grade 0-2 hydronephrosis; prevalence of high-grade hydronephrosis varied across sites (P = .002). Use of voiding cystourethrography also varied across sites (17.6%-88.9%); this difference persisted when controlling for age and hydronephrosis grade (P <.05). Use of other imaging studies did not significantly differ across sites. Use of screening voiding cystourethrography for infants with congenital hydronephrosis varies across practices. This variation persists when controlling for differences in age and ultrasound findings, suggesting that regional differences in patient demographics, provider/parental preferences, or referral patterns might contribute to practice variations in the evaluation of these patients.

There is a lack of standardized and quantifiable measures of touch function, for clinical work. Furthermore, it is not possible to make accurate diagnostic judgments of touch function before normative values are estimated. The objectives of this study were to establish adult norms of the perceptual threshold of touch (PTT) for the hands and feet according to age and gender and to determine the effect of right/left side, handedness, height, weight, and body mass index (BMI) on the PTT. The PTT was assessed by using a high-frequency transcutaneous electrical nerve stimulator (Hf/TENS) with self-adhesive skin electrodes in 346 adults. The PTT was identified as the level registered in mA at which the participants perceived a tingling sensation. The PTT for all participants was a median of 3.75 mA (range 2.50-7.25) in the hands and a median of 10.00 (range 5.00-30.00) in the feet. With increasing age an increase of the PTT was found. Men reported higher PTT than women. The right hand had higher PTT than the left. Handedness, height, weight, and BMI did not affect the PTT. Adult norms of the PTT in the hands for age, gender, and right/left side are presented for four age groups. The present study's estimate of the PTT in the hands could be used as adult norms. Adult norms for the feet could not be estimated because the PTT values in the feet showed a great variance.

Duration of Untreated Psychosis (DUP) is an important measure associated with outcome of psychosis. This first study in the UK compared DUP between adolescent and adult-onset individuals and explored whether the adolescent-onset group showed variations in DUP that could be accounted for by sociodemographic and selected risk factors. This naturalistic cohort study included 940 new first-episode psychosis cases aged 14-35years (136 adolescent-onset versus 804 adult-onset psychotic individuals) referred to nine Early Intervention Services for Psychosis in London (2003-2009). Sociodemographic characteristics, age of onset, family history of mental illness, duration of untreated psychosis, suicidality and substance use information were collected at entry to the services. Adolescents presented with significantly greater median DUP (179days) than adults (81days, p=0.005). Large differences in DUP were found amongst adolescent ethnic groups (median DUP: White: 454days; Black: 103days; Asian and mixed: 28.5days). In addition, younger age of onset and higher lifetime cannabis use were associated with longer treatment delay amongst adolescents. This study of DUP in adolescent-onset psychosis found it to be approximately twice the length of DUP amongst adults. For the adolescent White sub-group, DUP was far greater than the UK Department of Health target (<3months). Both the high rates of lifetime cannabis use and the lower age of onset might explain the long DUP in this ethnic group. Physicians need to be particularly vigilant about identifying and managing early psychosis in adolescents. © 2013.

Biliary atresia is a major cause of extrahepatic obstructive jaundice in neonates. Early Kasai operation is the gold standard of treatment. In this study, we evaluated the effectiveness of stool color card screening by using claims data from the National Health Insurance Research Database. This was a retrospective cohort study. Data from medical charts of all inpatients who were diagnosed with biliary atresia from 1996 to 2008 were collected from Taiwan's National Health Insurance Research Database. Patients who received a Kasai operation or liver transplant were identified by the Operation code. The patients' gender, age at admission, and type of operation were collected and analyzed. From 1996 to 2008, the overall incidence of biliary atresia was 1.48 per 10,000 live births. The median age at first admission for patients with suspected biliary atresia decreased after the implementation of stool color card screening (47 vs 43 days). The proportion of very late referral decreased from 9.5% to 4.9%. The median age of Kasai operation advanced from 51 to 48 days. The proportions of Kasai operation within 60 days of age were 68.9% before and 73.6% after screening program. Stool color card screening seemed to increase parents' and physicians' awareness of biliary atresia. It also was associated with a decline in the proportion of late referral. Thus, screening might be especially effective in areas with high a proportion of late referral. Improvements in the speed of workup and the operation room should be the focus of education and training in the future.

Background Respiratory syncytial virus (RSV) is the leading cause of acute respiratory illness in young children and results in significant economic burden. There is no vaccine to prevent RSV illness but a number of vaccines are in development. We conducted this study to estimate the costs of severe RSV illness requiring hospitalization among children <5 years and associated financial impact on households in Bangladesh. Data of this study could be useful for RSV vaccine development and also the value of various preventive strategies, including use of an RSV vaccine in children if one becomes available. Methods From May through October 2010, children aged <5 years with laboratory–confirmed RSV were identified from a sentinel influenza program database at four tertiary hospitals. Research assistants visited case–patients’ homes after hospital discharge and administered a structured questionnaire to record direct medical costs (physician consultation fee, costs for hospital bed, medicines and diagnostic tests); non–medical costs (costs for food, lodging and transportation); indirect costs (caregivers’ productivity loss), and coping strategies used by families to pay for treatment. We used WHO–Choice estimates for routine health care service costs. We added direct, indirect and health care service costs to calculate cost–per–episode of severe RSV illness. We used Monte Carlo simulation to estimate annual economic burden for severe RSV illness. Findings We interviewed caregivers of 39 persons hospitalized for RSV illness. The median direct cost for hospitalization was US$ 62 (interquartile range [IQR] = 43–101), indirect cost was US$ 19 (IQR = 11–29) and total cost was US$ 94 (IQR = 67–127). The median out–of–pocket cost was 24% of monthly household income of affected families (US$ 143), and >50% families borrowed money to meet treatment cost. We estimated that the median direct cost of RSV–associated hospitalization in children aged <5 years in Bangladesh was US$ 10 million (IQR: US$ 7–16 million), the median indirect cost was US$ 3.0 million (IQR: 2–5 million) in 2010. Conclusion RSV–associated hospitalization among children aged <5 years represents a substantial economic burden in Bangladesh. Affected families frequently incurred considerable out of pocket and indirect costs for treatment that resulted in financial hardship. PMID:28702175

An ostomy seems a safe alternative in neonates with an acute abdomen when immediate restoration of bowel continuity is deemed undesirable. Faced with several complications in our center, and the feeling we are not the only center with these complications, we decided to assess the rate and type of complications after both ostomy creation and closure. All data regarding neonates (<30 days of age) who underwent a laparotomy for a suspected abdominal emergency in the period 2000 to 2010 were retrospectively analyzed. These data included demographics such as gender, gestational age, and birth weight. Disease etiology was defined and various features of the enterostomy were analyzed. These features included type, location, time to ostomy take down, and complications and mortality directly related to both creation and closure of the ostomy. A total of 155 patients who underwent a laparotomy for suspect acute abdomen were identified. Median gestational age was 33 weeks (range 25 to 40) and median birth weight was 1926 g (range 560 to 4380). Median age at laparotomy was 8 days (range 0 to 30). Indications for surgery were necrotizing enterocolitis (n = 38), spontaneous intestinal perforation (n = 11), intestinal atresia (n = 9) or obstruction (n = 5), and volvulus (n = 4). An ostomy was created in 67 patients (67/155: 43%): 38 boys and 29 girls. There were 8 jejuno-, 49 ileo-, and 10 colostomies created. In almost all cases (94%), a mucous fistula was also constructed.In 23 patients (23/67: 34%) ostomy-related complications occurred. Most frequent were high output ostomy (n = 10) and necrosis of the enterostomy (n = 7). Due to either one of the complications, nine patients (9/67: 13%) needed a reoperation.In this study, 11 patients died before ostomy closure could occur. In 53 patients, the ostomy was closed after a median of 107 days (range 4 to 299).After ostomy closure, complications occurred in 13 cases (13/53: 25%). Seven patients (7/53: 13%) needed another reoperation because of anastomotic leakage (n = 4), adhesions (n = 2), or incisional hernia (n = 1). There was no closure-related mortality. Although creating a temporary ostomy in newborns is preferable in certain situations, there is a considerable occurrence of complications and reoperations.

METHODS: Medical records of patients with brainstem gliomas treated from July 2001 to December 2012 were reviewed to identify treatment outcomes of surgery, radiation therapy and chemotherapy and associated prognostic factors in a Saudi population. RESULTS: We analyzed 49 brain stem glioma (BSG) patients from July 2001 to December 2012; 31 of them were males (63.3%) with a median age of 12.6 years (range: 8-64 mo). Twenty-two patients (44.9%) had diffuse intrinsic pontine gliomas (DIPG) and 15 (30.6%) presented with focal/tectal BSG. Histopathology was available in 30 patients (61.2%). Median survival time for the whole cohort was 1.5 years. One and two year OS rates were 51.1% and 41.9% respectively. Two year OS rates for focal/tectal, dorsally exophytic, cervicomedullary and DIPG tumors were 60%, 33.3%, 33.3% and 13.6% respectively (P < 0.0001). Significant prognostic factors related to OS were age at diagnosis (worse for > 18 years) P = 0.01, KPS < 70 P = 0.02, duration of symptoms (< 60 d) P = 0.002, histology (better for favorable) P = 0.002, surgery (maximal resection) P = 0.002, and concurrent chemotherapy with radiation therapy in DIPG (better if given) P = 0.01. CONCLUSION: BSG, especially the DIPG subgroup, had a dismal prognosis, needing more aggressive neurosurgical, radiation and chemotherapy techniques, while focal and tectal tumors were found to have a better prognosis.

Several cytokines have been detected in human milk but their relative concentrations differ among women and vary over time in the same person. The drivers of such differences have been only partially identified, while the effect of luminal cytokines in the fine-regulation of the intestinal immune system is increasingly appreciated. The aim of this study was to investigate the associations between obstetrical complications and human milk cytokine profiles in a cohort of Peruvian women giving birth to Low Birth Weight (LBW) infants. Colostrum and mature human milk samples were collected from 301 Peruvian women bearing LBW infants. The concentration of twenty-three cytokines was measured using the Luminex platform. Ninety-nine percent of women had at least one identified obstetrical complication leading to intra-uterine growth restriction and/or preterm birth. Median weight at birth was 1,420g; median gestational age 31 weeks. A core of 12 cytokines, mainly involved in innate immunity and epithelial cell integrity, was detectable in most samples. Maternal age, maternal infection, hypertensive disorders, preterm labor, and premature rupture of membranes were associated with specific cytokine profiles both in colostrum and mature human milk. Mothers of Very LBW (VLBW) neonates had significantly higher concentrations of chemokines and growth factor cytokines both in their colostrum and mature milk compared with mothers of larger neonates. Thus, maternal conditions affecting pregnancy duration and in utero growth are also associated with specific human milk cytokine signatures. Copyright © 2017. Published by Elsevier B.V.

To determine single year age-specific anti-Müllerian hormone (AMH) standard deviation scores (SDS) for women associated to normal ovarian function and different ovarian disorders resulting in sub- or infertility. Determination of particular year median and mean AMH values with standard deviations (SD), calculation of age-independent cut off SDS for the discrimination between normal ovarian function and ovarian disorders. Single-year-specific median, mean, and SD values have been evaluated for the Beckman Access AMH immunoassay. While the decrease of both median and mean AMH values is strongly correlated with increasing age, calculated SDS values have been shown to be age independent with the differentiation between normal ovarian function measured as occurred ovulation with sufficient luteal activity compared with hyperandrogenemic cycle disorders or anovulation associated with high AMH values and reduced ovarian activity or insufficiency associated with low AMH, respectively. These results will be helpful for the treatment of patients and the ventilation of the different reproductive options. Copyright © 2017 Elsevier B.V. All rights reserved.

Recent population-based studies have shown a low risk of esophageal adenocarcinoma (EAC) in patients with nondysplastic Barrett's esophagus (NDBE). We evaluated whether persistence of NDBE over multiple consecutive surveillance endoscopic examinations could be used in risk stratification of patients with Barrett's esophagus (BE). We performed a multicenter outcomes study of a large cohort of patients with BE. Based on the number of consecutive surveillance endoscopies showing NDBE, we identified 5 groups of patients. Patients in group 1 were found to have NDBE at their first esophagogastroduodenoscopy (EGD). Patients in group 2 were found to have NDBE on their first 2 consecutive EGDs. Similarly, patients in groups 3, 4, and 5 were found to have NDBE on 3, 4, and 5 consecutive surveillance EGDs. A logistic regression model was built to determine whether persistence of NDBE independently protected against development of cancer. Of a total of 3515 patients with BE, 1401 patients met the inclusion criteria (93.3% white; 87.5% men; median age, 60 ±17 years). The median follow-up period was 5 ± 3.9 years (7846 patient-years). The annual risk of EAC in groups 1 to 5 was 0.32%, 0.27%, 0.16%, 0.2%, and 0.11%, respectively (P for trend = .03). After adjusting for age, sex, and length of BE, persistence of NDBE, based on multiple surveillance endoscopies, was associated with a gradually lower likelihood of progression to EAC. Persistence of NDBE over several endoscopic examinations identifies patients who are at low risk for development of EAC. These findings support lengthening surveillance intervals or discontinuing surveillance of patients with persistent NDBE. Copyright © 2013 AGA Institute. Published by Elsevier Inc.

Squamous cell carcinoma (SCC) is an uncommon histologic subtype of bladder cancer with limited data on treatment patterns, outcomes, and prognostic factors. "Real world" information might inform decision-making, prognostic estimates, and clinical trial designs. A retrospective review of patients with tissue-confirmed bladder SCC treated at Cleveland Clinic from 2007 to 2016 was performed. Data on patient characteristics, treatment patterns, and clinical follow-up were extracted. Univariate analysis was used to identify predictors of overall survival (OS), recurrence-free survival (RFS) and time to recurrence. Of 58 identified patients, 42 had complete data available. Median age at diagnosis was 67 years (range, 37-90). Hematuria was the most common (71%) presenting symptom; 32 patients had pure SCC and 10 predominant/extensive squamous differentiation without major differences noted in clinicopathologic variables or outcomes among those 2 groups. Overall, 35 patients underwent cystectomy with 5 receiving neoadjuvant and 1 adjuvant chemotherapy, whereas 3 had chemotherapy for recurrent disease. Of patients with cystectomy, most had locally advanced disease (75% pT3/4, 35% pN+). Overall, 10 patients progressed and 14 died; median OS was not reached. The 2-year estimated OS, RFS, and cumulative incidence of recurrence were 61% ± 9%, 50% ± 9%, and 32% ± 9%, respectively. Hydronephrosis, older age (70 years or older), lymphovascular invasion, nodal metastases, and advanced T stage were associated with 1 or more poor outcomes. In patients with resectable bladder SCC, radical cystectomy remains the main treatment modality. The role of perioperative chemotherapy remains unclear. The identified prognostic factors might be helpful for prognostication, treatment discussion, and trial eligibility/stratification. Copyright © 2017 Elsevier Inc. All rights reserved.

Risk of infection with Pseudomonas aeruginosa in cystic fibrosis (CF) may be associated with environmental factors. To determine whether residential location is associated with risk of first acquisition of P. aeruginosa. We performed bronchoalveolar lavage and upper airway cultures in children newly diagnosed with CF to identify infection with P. aeruginosa during infancy and early childhood. Children were assessed according to their residence in a regional or metropolitan area. Multilocus sequence typing was used to determine P. aeruginosa genotype. An environmental questionnaire was also administered. A total of 105 of 120 (87.5%) infants diagnosed with CF were included in this study. Diagnosis in 65 infants (61.9%) followed newborn screening at mean age of 4.6 weeks. Sixty subjects (57.1%) were homozygous ΔF508, and 47 (44.8%) were female. Fifty-five (52.3%) infants were regional, of whom 26 (47.3%), compared with 9 of 50 (18.0%) metropolitan children, acquired infection with P. aeruginosa (odds ratio, 4.084; 95% confidence interval, 1.55-11.30). Age at acquisition was similar (regional: median, 2.31 yr; range, 0.27-5.96 yr; metropolitan: median, 3.10 yr, range, 0.89-3.70 yr). Strain typing identified P. aeruginosa genotypes often encountered in different ecological settings and little evidence of cross-infection. Ninety questionnaires (85.7%) were completed. Those who acquired P. aeruginosa were more likely to be living in a household that used water sprinkler systems (P = 0.032), but no differences were identified to explain increased risk of acquisition of P. aeruginosa in regional children. Geographical difference in residence of children with CF was associated with increased risk of first acquisition of P. aeruginosa, usually with strains associated with the environment rather than with cross-infection.

To describe the survival of a large nonobstructive hypertrophic cardiomyopathy (NO-HCM) cohort and to identify risk factors for increased mortality in this population. Patients were identified from the Mayo Clinic HCM database from January 1, 1975, through November 30, 2006, for this retrospective observational study. Patients with resting or provocable left ventricular outflow tract gradients were excluded. Echocardiographic, clinical, and genetic data were compared between subgroups, and survival data were compared with expected population rates. A total of 706 patients with NO-HCM were identified. During median follow-up of 5 years (mean, 7 years), there were 208 deaths. Overall survival was no different than expected compared with age- and sex-matched white US population mortality rates (P=.77). Independent predictors of death were age at diagnosis, "burned out" HCM, and history of transient ischemic attack or stroke; use of an implantable cardioverter defibrillator (ICD) was inversely related to death. After exclusion of patients with an ICD, there was no difference in survival compared with age- and sex- matched individuals (P=.39); age, previous transient ischemic attack/stroke, and burned out HCM were predictors of death. In this cohort, patients with NO-HCM had similar survival rates as age- and sex-matched white US population mortality rates. Although use of an ICD was inversely related to death, no differences in overall survival were seen after those patients were excluded. Burned out HCM was independently associated with an increased risk of death, identifying a subset of patients who may benefit from more aggressive therapies.

Quality of life (QoL) is impaired in childhood obesity, but the literature on this is all from Western countries. Aim. To test for impairment of QoL in obese children in Malaysia, using parent-reported and child-reported QoL. Health-related Quality of Life was measured using the Paediatric Quality of Life Inventory version 4.0. Comparison of QoL between a community sample of 90 obese children (as defined by US CDC and Cole-IOTF definitions), median age 9.5 y (interquartile range [IQR] 8.6, 10.5 y) and 90 control children of healthy weight (BMI less than the 85th centile of US reference data), median age 10.0 y (IQR 9.6, 10.5 y). Children were matched pair-wise for age, gender, and ethnic group, and controls were recruited from schools in the same area as obese participants. For child self-report, the healthy weight group had significantly higher QoL for the physical (median 82.9, IQR 65.7, 90.6), and psychosocial domains (median, 73.3, IQR 64.4, 83.3), and total QoL (median 76.1, IQR 64.1, 84.8) compared to the obese group (median 67.2, IQR 59.4, 81.3; median 62.5, IQR 53.3, 75.4; median 60.9, IQR 50.8, 73.9; all p < 0.001). There were no significant differences between the obese and healthy weight group for parent-reported physical health, psychosocial health, or total QoL. Obese children in Malaysia have markedly poorer QoL than their peers, but this is not evident when parent reports of QoL are used.

To determine the median age of natural menopause in United Arab Emirates women, the factors affecting that age and the prevalence of climacteric symptoms amongst those women. A population-based survey was conducted on a community sample of United Arab Emirates women who had had natural menopause defined as cessation of menstruation for at least 6 months at the end of reproductive years. A total of 742 women aged 40 years and above were recruited from both urban and rural areas of the country using the multi-stage stratified cluster sampling technique. Data were collected using a structured questionnaire and face to face interviews and included a number of familial, reproductive and life-style variables. The median age of the menopause in the United Arab Emirates is 48 years (mean = 47.3 +/- 3.29, range 40-59). This is significantly lower than the median age reported from the West (50.3 years). The subject median age of the menopause was significantly related to that of the mother (P < 0.001), older sister (P < 0.001), parity (P < 0.0001) and the previous use of oral contraceptive pills for more than 1 year (P < 0.001). Hot flushes were the commonest feature of the menopause occurring in 45% of women. The age of natural menopause in United Arab Emirates women, as in other developing countries, is less than in Western women and may be influenced by genetic factors, parity and previous use of oral contraceptives. Climacteric symptomatology, however, is similar in the different patient groups.

Between January and August 2011, the canton of Geneva, Switzerland, experienced a large measles outbreak with 219 cases (47 cases per 100,000 inhabitants) in the context of an extensive epidemic in a neighbouring region of France. Most cases were young adults (median age: 18 years), often unaware of their vaccination status. The vast majority of cases were either not (81%) or incompletely vaccinated (8%). Thirty clusters with a total of 119 cases and a median cluster size of three (range: 2–15 cases) were identified. Overall, 44 cases were imported or linked to imported cases. Of 73 contacts of cases who were quarantined, 50 developed measles and caused six secondary cases. This compares to 81 secondary cases among 173 non-quarantined cases (relative risk: 0.26; 95% confidence interval: 0.06–0.65), demonstrating the effectiveness of well targeted quarantine measures in reducing transmission.

Assessment of non-carcinogenic risks from chemical substances ingested with drinking water included peroral, skin and inhalation routes of contact with water. The study was carried out for children aged 3-6 years living in 4 districts (zones) of the city of Kazan. Regional exposure factors (REF) at the median (Me) and the 95-th Percentile (95P) levels were identified according to the results of the questionnaire survey. The value of total hazard indices (THI) calculated with application of REF at the median (Me) and the 95-th Percentile (95P) levels made THIMe = 14.2 and 17.1, and THI 95perc = 13.03 and 16.3 in zones with a combined type of water supply. The ingestion of chemical substances with drinking water in different zones of the city of Kazan implies, alert and high levels of non-carcinogenic health risk for the child population.

To examine the relation of the health-related practices of expectant mothers during pregnancy and fatigue in mother and prenatal attachment. Descriptive study. Sakarya Training and Research Hospital, Turkey, between February and April 2016. The study sample consisted of pregnant women (at least 20-week gestation) aged 18 years or above (n=211) who applied to prenatal care services and agreed to participate in the study. The data were collected through a Personal Information Form, Brief Fatigue Inventory (BFI) and the Prenatal Attachment Inventory (PAI). The PAI medians of the participants were 55 [42-64], and the BFI medians were 30 [23-42], and a negative, statistically significant relationship was found between BFI and PAI (r= -0.184, p=0.007). Expectant mothers who develop positive health behaviors during pregnancy feel less fatigue and positively affect the prenatal attachment. It is important to evaluate prenatal attachment and identify the mother with low attachment scores.

Non-AIDS-related malignancies now represent a frequent cause of death among HIV-infected patients. Albeit bladder cancer is one of the most common malignancies worldwide, it has been rarely reported among HIV-infected patients. We wished to assess the prevalence and characteristics of bladder cancer in HIV-infected patients. We conducted a single center retrospective study from 1998 to 2013 in a university hospital in Paris. Cases of bladder cancer among HIV-infected patients were identified using the electronic records of the hospital database and of the HIV-infected cohort. Patient characteristics and outcomes were retrieved from patients charts. A systematic review of published cases of bladder cancers in patients with HIV-infection was also performed. During the study period we identified 15 HIV-infected patients (0.2% of the cohort) with a bladder cancer. Patients were mostly men (73%) and smokers (67%), with a median age of 56 years at cancer diagnosis. Bladder cancer was diagnosed a median of 14 years after HIV-infection. Most patients were on ART (86%) with median current and nadir CD4 cell counts of 506 and 195 cells/mm3, respectively. Haematuria (73%) was the most frequent presenting symptom and HPV-associated lesions were seen in 6/10 (60%) patients. Histopathology showed transitional cell carcinoma in 80% and a high proportion of tumors with muscle invasion (47%) and high histologic grade (73%). One-year survival rate was 74.6%. The systematic review identified 13 additional cases of urothelial bladder cancers which shared similar features. Bladder cancers in HIV-infected patients remain rare but may occur in relatively young patients with a low nadir CD4 cell count, have aggressive pathological features and can be fatal.

Determinants of cardiomyocyte injury as quantified by high-sensitivity cardiac troponin I (cTnI) in young and healthy individuals, and sex-specific 99th percentiles are largely unknown. Our study included 2077 adults from the general population aged 25-41 years without cardiovascular disease. cTnI was measured using a high-sensitivity assay. We performed stepwise backward linear regression analyses to identify variables independently associated with hs-cTnI levels, and calculated narrow-sense heritability from 1638-genotyped participants. Median age was 37 years. cTnI was quantifiable in all but 11 participants (99.5 %). Median (interquartile range) cTnI was significantly higher in men than in women [0.99 (0.71; 1.65) versus 0.47 (0.33; 0.71) ng/L, p < 0.0001]. The 99th percentile of cTnI was 15.79 ng/L in men and 5.11 ng/L in women. Out of 46 variables, 22 independent determinants for cTnI were identified. The strongest associations were observed with sex, age, systolic blood pressure, heart rate, left ventricular mass, N-terminal pro B-type natriuretic peptide, and creatine kinase (all p < 0.0001). The final model explained 36 % of the overall cTnI variability. Heritability of cTnI was estimated to be 29 % (p = 0.005), but became non-significant when the residuals of the multivariable model were used for analysis (5 %, p = 0.36). Sex, age, and systolic blood pressure belong to the strongest determinants of hs-cTnI in healthy adults. The 99th percentile was three times higher in men compared to women. Hence, sex-specific cut-off values may be preferable when applying hs-cTnI for screening purposes. Our results may also improve the interpretation of cTn levels in daily clinical practice.

Symptom assessment by computers is only effective if it provides valid results and is perceived as useful for clinical use by the end users: patients and health care providers. To identify factors associated with discontinuation, time expenditure, and patient preferences of the computerized symptom assessment used in an international multicenter data collection project: the European Palliative Care Research Collaborative-Computerized Symptom Assessment. Cancer patients with incurable metastatic or locally advanced disease were recruited from 17 centers in eight countries, providing 1017 records for analyses. Observer-based registrations and patient-reported measures on pain, depression, and physical function were entered on touch screen laptop computers. The entire assessment was completed by 94.9% (n = 965), with median age 63 years (range 18-91 years) and median Karnofsky Performance Status (KPS) score of 70 (range 20-100). Predictive factors for noncompletion were higher age, lower KPS, and more pain (P ≤ 0.012). Time expenditure among completers increased with higher age, male gender, Norwegian nationality, number of comorbidities, and lower physical functioning (P ≤ 0.007) but was inversely related to pain levels and tiredness (P ≤ 0.03). Need for assistance was predicted by higher age, nationality other than Norwegian, lower KPS, and lower educational level (P < 0.001). More than 50% of patients preferred computerized assessment to a paper and pencil version. The high completion rate shows that symptom assessment by computers is feasible in patients with advanced cancer. However, reduced performance status reduces compliance and increases the need for assistance. Future work should aim at identifying the minimum set of valid screening questions and refine the software to optimize symptom assessment and reduce respondent burden in frail patients.

2017-10-01

The mainstay of current schistosomiasis control programs is mass preventive chemotherapy of school-aged children with praziquantel. This treatment is delivered through school-based, community-based, or combined school- and community-based systems. Attaining very high coverage rates for children is essential in mass schistosomiasis treatment programs, as is ensuring that there are no persistently untreated subpopulations, a potential challenge for school-based programs in areas with low school enrollment. This review sought to compare the different treatment delivery methods based both on their coverage of school-aged children overall and on their coverage specifically of non-enrolled children. In addition, qualitative community or programmatic factors associated with high or low coverage rates were identified, with suggestions for overall coverage improvement. This review was registered prospectively with PROSPERO (CRD 42015017656). Five hundred forty-nine publication of potential relevance were identified through database searches, reference lists, and personal communications. Eligible studies included those published before October 2015, written in English or French, containing quantitative or qualitative data about coverage rates for MDA of school-aged children with praziquantel. Among the 22 selected studies, combined community- and school-based programs achieved the highest median coverage rates (89%), followed by community-based programs (72%). School-based programs had both the lowest median coverage of children overall (49%) and the lowest coverage of the non-enrolled subpopulation of children. Qualitatively, major factors affecting program success included fear of side effects, inadequate education about schistosomiasis, lack of incentives for drug distributors, and inequitable distribution to minority groups. This review provides an evidence-based framework for the development of future schistosomiasis control programs. Based on our results, a combined community and school-based delivery system should maximize coverage for both in- and out-of-school children, especially when combined with interventions such as snacks for treated children, educational campaigns, incentives for drug distributors, and active inclusion of marginalized groups.

Muscle atrophy is seen in patients with metal-on-metal (MOM) hip implants, probably because of inflammatory destruction of the musculo-tendon junction. However, like pseudotumors, it is unclear when atrophy occurs and whether it progresses with time. Our objective was to determine whether muscle atrophy associated with MOM hip implants progresses with time. We retrospectively reviewed 74 hips in 56 patients (32 of them women) using serial MRI. Median age was 59 (23-83) years. The median time post-implantation was 83 (35-142) months, and the median interval between scans was 11 months. Hip muscles were scored using the Pfirrmann system. The mean scores for muscle atrophy were compared between the first and second MRI scans. Blood cobalt and chromium concentrations were determined. The median blood cobalt was 6.84 (0.24-90) ppb and median chromium level was 4.42 (0.20-45) ppb. The median Oxford hip score was 34 (5-48). The change in the gluteus minimus mean atrophy score between first and second MRI was 0.12 (p = 0.002). Mean change in the gluteus medius posterior portion (unaffected by surgical approach) was 0.08 (p = 0.01) and mean change in the inferior portion was 0.10 (p = 0.05). Mean pseudotumor grade increased by 0.18 (p = 0.02). Worsening muscle atrophy and worsening pseudotumor grade occur over a 1-year period in a substantial proportion of patients with MOM hip implants. Serial MRI helps to identify those patients who are at risk of developing worsening soft-tissue pathology. These patients should be considered for revision surgery before irreversible muscle destruction occurs.

Purpose Sunitinib is an oral tyrosine kinase inhibitor of VEGF, PDGF, c-KIT, and flt-3 receptors. A pediatric phase I study of sunitinib capsules identified the maximum tolerated dose as 15 mg/m2/day. This study was conducted to evaluate sunitinib given as a powder formulation. Methods Sunitinib 15 mg/m2 was administered orally daily for 4 weeks on/2 weeks off to patients <21 years old with refractory solid tumors. Sunitinib capsules were opened, and the powder sprinkled onto applesauce or yogurt. Plasma levels of sunitinib and an active metabolite, SU12662, were measured, and pharmacokinetic parameters were estimated. Results 12 patients, median age 13 (range 4–21) years, were treated. The most common first-cycle toxicities were leucopenia (n = 6), fatigue (n = 5), neutropenia (n = 4), and hypertension (n = 4). Three patients had dose-limiting toxicities (DLTs) in cycle 1 (dizziness/back pain, hand–foot syndrome, and intratumoral hemorrhage/hypoxia). A median peak plasma sunitinib concentration of 21 (range 6–36) ng/ml was reached at a median of 4 (range 4–8) h after the first dose. The median exposure (AUC0–48) was 585 (range 196–1,059) h ng/l. The median half-life was 23 (range 13–36) h. The median trough concentration measured before day 14 dosing was 32 (range 12–58) ng/ml. Conclusions The pharmacokinetic profile of sunitinib appears similar between a powder formulation and published data using capsules. The powder formulation allows patients unable to swallow capsules to receive sunitinib. PMID:22179104

Abstract Objective To conduct a systematic review of emergency care in low- and middle-income countries (LMICs). Methods We searched PubMed, CINAHL and World Health Organization (WHO) databases for reports describing facility-based emergency care and obtained unpublished data from a network of clinicians and researchers. We screened articles for inclusion based on their titles and abstracts in English or French. We extracted data on patient outcomes and demographics as well as facility and provider characteristics. Analyses were restricted to reports published from 1990 onwards. Findings We identified 195 reports concerning 192 facilities in 59 countries. Most were academically-affiliated hospitals in urban areas. The median mortality within emergency departments was 1.8% (interquartile range, IQR: 0.2–5.1%). Mortality was relatively high in paediatric facilities (median: 4.8%; IQR: 2.3–8.4%) and in sub-Saharan Africa (median: 3.4%; IQR: 0.5–6.3%). The median number of patients was 30 000 per year (IQR: 10 296–60 000), most of whom were young (median age: 35 years; IQR: 6.9–41.0) and male (median: 55.7%; IQR: 50.0–59.2%). Most facilities were staffed either by physicians-in-training or by physicians whose level of training was unspecified. Very few of these providers had specialist training in emergency care. Conclusion Available data on emergency care in LMICs indicate high patient loads and mortality, particularly in sub-Saharan Africa, where a substantial proportion of all deaths may occur in emergency departments. The combination of high volume and the urgency of treatment make emergency care an important area of focus for interventions aimed at reducing mortality in these settings. PMID:26478615

Adequate and timely provision of nutritional support is a crucial component of care of the critically ill burn patient. The goal of this study was to assess a single center's consistency with Society of Critical Care Medicine/American Society for Parenteral and Enteral Nutrition (SCCM/ASPEN) guidelines for nutritional support in critically ill patients. Acutely burned patients >45kg in weight admitted to a regional burn center during a two-year period and who required 5 or more days of full enteral nutritional support were eligible for inclusion in this retrospective review. Specific outcomes evaluated include time from admission to feeding tube placement and enteral feeding initiation and percent of nutritional goal received within the first week of hospital stay. Descriptive statistics were used for all analyses. IRB approval was obtained. Thirty-seven patients were included in this retrospective review. Median age of patients was 44.9 years (IQR: 24.2-55.1), and median burn injury size was 30% (IQR: 19-47). Median time to feeding tube placement was 31.1h post admission (IQR: 23.6-50.2h), while median time to initiation of EN was 47.9h post admission (IQR: 32.4-59.9h). The median time required for patients to reach 60% of caloric goal was 3 days post-admission (IQR: 3-4.5). The median time for initiation of enteral nutrition was within the SCCM/ASPEN guidelines for initial nutrition in the critically ill patient. This project identified a 16h time lag between placement of enteral access and initiation of enteral nutrition. Development of a protocol for feeding tube placement and enteral nutrition management may optimize early nutritional support in the acutely injured burn patient.

Fifty-six cases of Down syndrome were identified in a population of women who had undergone maternal serum triple marker screening [alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and unconjugated oestriol (uE3) analyses]. These affected pregnancies represented all known cases present in the population of 34,368 women screened. Using a 1:270 mid-trimester Down syndrome risk to define the screen-positive group, 42 affected pregnancies were screen-positive (medians: AFP = 0.79 MOM, hCG = 2.13 MOM, uE3 = 0.62 MOM, age 34.6 years) and 14 pregnancies were screen-negative (medians: AFP = 0.82 MOM, hCG = 1.57 MOM, uE3 = 0.92 MOM, age 24.2 years). Four affected pregnancies were associated with in utero death and each of these cases was associated with relatively extreme values of AFP, hCG, and uE3, including the three highest levels of hCG in the entire series of Down syndrome pregnancies. Twenty-nine (15 screen-positive and 14 screen-negative) affected pregnancies resulted in liveborns. Down syndrome pregnancies had a significantly shorter gestational term than controls, and Down syndrome babies were also lighter than controls, even after adjustment for sex and gestational age. In affected pregnancies, a low uE3 level appeared to be associated with a greater chance of a small-for-gestational age baby. No correlations could be demonstrated between AFP or hCG levels and gestational age-adjusted term weight. Based on this small series, it would appear that uE3 may be particularly useful in detecting those Down syndrome cases associated with small-for-gestational age fetuses. A very high hCG value may indicate a higher probability of fetal death.

Background While an increased risk of thyroid cancer from post-Chernobyl exposure to Iodine-131 (I-131) in children and adolescents has been well-documented, risks of other cancers or leukemia as a result of residence in radioactively contaminated areas remain uncertain. Methods We studied non-thyroid cancer incidence in a cohort of about 12,000 individuals from Belarus exposed under age of 18 years to Chernobyl fallout (median age at the time of Chernobyl accident of 7.9 years). During 15 years of follow-up from1997 through 2011, 54 incident cancers excluding thyroid were identified in the study cohort with 142,968 person-years at risk. We performed Standardized Incidence Ratio (SIR) analysis of all solid cancers excluding thyroid (n=42), of leukemia (n=6) and of lymphoma (n=6). Results We found no significant increase in the incidence of non-thyroid solid cancer (SIR=0.83, 95% Confidence Interval [CI]: 0.61; 1.11), lymphoma (SIR=0.66, 95% CI: 0.26; 1.33) or leukemia (SIR=1.78, 95% CI: 0.71; 3.61) in the study cohort as compared with the sex-, age- and calendar-time-specific national rates. These findings may in part reflect the relatively young age of study subjects (median attained age of 33.4years), and long latency for some radiation-related solid cancers. Conclusions We found no evidence of statistically significant increases in solid cancer, lymphoma and leukemia incidence 25 years after childhood exposure in the study cohort; however, it is important to continue follow-up non-thyroid cancers in individuals exposed to low-level radiation at radiosensitive ages.

Purpose Diagnosis of Rett syndrome (RTT) is often delayed. We sought to determine type of physician who typically makes the diagnosis of RTT and to identify risk factors for delayed diagnosis. Methods One-thousand eighty-five participants from the multicenter longitudinal RTT natural history study with classic and atypical RTT were recruited from 2006 to 2014. Age of diagnosis, diagnostician, diagnostic criteria, clinical and developmental data were collected. Results Among 919 classic and 166 atypical RTT participants, median diagnosis age was 2.7 years (interquartile range 2.0–4.1) in classic and 3.8 years (interquartile range 2.3–6.9) in atypical RTT. Pediatricians made the diagnosis of classic RTT rarely (5.2%); however, proportion diagnosed by pediatricians increased since 2006. Since the first diagnostic criteria, the age of diagnosis decreased among subspecialists but not pediatricians. Odds of a pediatrician making the diagnosis of classic RTT were higher if a child stopped responding to parental interaction, and lower if they possessed gastro-esophageal reflux, specific stereotypies, lost babbling or the ability to follow commands. Delayed acquisition of basic gross motor skills or finger feeding were associated with younger diagnosis; delayed acquisition of higher level fine motor skills, later onset of supportive features, and normal head circumference were associated with late diagnosis. 33% with microcephaly before 2.5 years were diagnosed after the median age of 2.7 years. Conclusions Age of RTT diagnosis has improved among subspecialists, and pediatricians have made the diagnosis of classic RTT more frequently since 2006. Strategies for educating diagnosticians should incorporate specific risk factors for delayed diagnosis. PMID:25801175

In patients with haemophilia A, factor VIII (FVIII) prophylaxis reduces bleeding frequency and joint damage compared with on-demand therapy. To assess the effect of prophylaxis initiation age, magnetic resonance imaging (MRI) was used to evaluate bone and cartilage damage in patients with severe haemophilia A. In this cross-sectional, multinational investigation, patients aged 12–35 years were assigned to 1 of 5 groups: primary prophylaxis started at age <2 years (group 1); secondary prophylaxis started at age 2 to <6 years (group 2), 6 to <12 years (group 3), or 12−18 years (group 4); or on-demand treatment (group 5). Joint status at ankles and knees was assessed using Compatible Additive MRI scoring (maximum and mean ankle; maximum and mean of all 4 joints) and Gilbert scores in the per-protocol population (n = 118). All prophylaxis groups had better MRI joint scores than the on-demand group. MRI scores generally increased with current patient age and later start of prophylaxis. Ankles were the most affected joints. In group 1 patients currently aged 27−35 years, the median of maximum ankle scores was 0.0; corresponding values in groups 4 and 5 were 17.0 and 18.0, respectively [medians of mean index joint scores: 0.0 (group 1), 8.1 (group 2) and 13.8 (group 4)]. Gilbert scores revealed outcomes less pronounced than MRI scores. MRI scores identified pathologic joint status with high sensitivity. Prophylaxis groups had lower annualized joint bleeds and MRI scores vs. the on-demand group. Primary prophylaxis demonstrated protective effects against joint deterioration compared with secondary prophylaxis. PMID:25470205

The prevalence of Wolff-Parkinson-White (WPW) syndrome varies between 0.68 and 1.7/1000. The epidemiological profile may be modified after the introduction of transcatheter interventions. The aim of this study is to investigate the epidemiological trends of the WPW syndrome in a general population during a period with available and reimbursed transcatheter ablation. Data of WPW patients <50 years old were retrieved from our national database (2000-2010). We identified 6086 (61% male) patients, accounting for an overall prevalence of 0.36/1000 with a peak of 0.61/1000 in ages 20-24 years. The risk of death and sudden death was 0.071% and 0.02% per patient-year, respectively. The 42 deaths occurred at a median age of 29 years. Associated congenial heart disease was noted in 158 (2.6%) patients, including 42 with Ebstein's anomaly that increased the mortality risk (P=0.001, OR=8.5). In those without congenital heart disease, myocardial dysfunction occurred in 115 (1.9%) patients and increased the risk of death (P<0.001, OR=10.6) and sudden death. Radiofrequency catheter ablation was performed in 2527 patients at a median age of 25.7 years (4.54% per patient-year, discharge mortality 0.16%); 11 (0.4%) before the age of 5, and 2231 (88%) after the age of 15. Whereas repeated ablation procedures accounted for 6.0% of the procedures, those in Ebstein's patients were 25%. Radiofrequency catheter ablation is already a common treatment for WPW patients, particularly during young adulthood, which accounts for a lower prevalence. Myocardial dysfunction and associated congenital heart disease remain as risks of mortality. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

This study aims to evaluate associations between variations in genes involved in the metabolism of environmental chemicals and steroid hormones and risk of menopause in smokers. Survival analysis was performed on 410 eligible participants from the Penn Ovarian Aging study (ongoing for 14 years), a cohort study of late-reproductive-age women. Single nucleotide polymorphisms at the following loci were studied: COMT Val158Met, CYP1B1*4 Asn452Ser, CYP1B1*3 Leu432Val, and CYP3A4*1B. Significant interactions between smoking and single nucleotide polymorphisms were observed in European-American carriers of CYP3A4*1B and CYP1B1*3, supporting a greater risk of menopause entry compared with those not carrying these alleles. Among CYP1B1*3 carriers, smokers had a greater risk of menopause entry than nonsmokers (adjusted hazard ratio [HR], 2.26; 95% CI, 1.4-3.67; median time to menopause, 10.42 and 11.07 y, respectively). No association between smoking and menopause was identified in CYP1B1 wild types. Among CYP3A4*1B carriers, smokers were at greater risk for menopause entry than nonsmokers (adjusted HR, 15.1; 95% CI, 3.31-69.2; median time to menopause, 11.36 and 13.91 y, respectively). Risk of menopause entry in CYP3A4 wild types who smoked was far lower (adjusted HR, 1.59; 95% CI, 1.03-2.44). Heavily smoking CYP1B1*3 carriers (adjusted HR, 3.0; 95% CI, 1.54-5.84; median time to menopause, 10.41 y) and heavily smoking CYP3A4*1B carriers (adjusted HR, 17.79; 95% CI, 3.21-98.65; median time to menopause, 5.09 y) had the greatest risk of menopause entry. Our finding that the risk of menopause entry in European-American smokers varies depending on genetic background represents a novel gene-environment interaction in reproductive aging.

Survivors of childhood cancer carry a substantial burden of long-term morbidity; personal risk awareness is critical to ensure survivors' engagement in early detection/management of complications. The impact of education provided in survivorship clinics on survivors' understanding of their personal health risks is unclear. Patients diagnosed with cancer at age 21 years or younger and at 2 or more years off therapy completed questionnaires about awareness of personal risk for therapy-related complications at T0 (first survivorship clinic visit) and at T1 to T5 (subsequent visits). After questionnaire completion at each clinic visit, survivors received education tailored to personal risk. A total of 369 survivors completed 1,248 visits (median, three visits; range, one to six visits). The median age at cancer diagnosis was 11 years (range, 0 to 21 years); the median age at T0 was 24 years (range, 5 to 57 years); 38% were white; 45% had leukemia; and 34% received hematopoietic cell transplantation. The cohort was at risk for a median of six (range, one to nine) complications. Awareness increased from 38.6% at T0 to 66.3% at T3. Generalized estimating equations (that adjusted for diagnosis, hematopoietic cell transplantation, race/ethnicity, and patient/parent education) showed significant gains in awareness from T0 to T1 (P < .001), T1 to T2 (P = .03), and T2 to T3 (P < .001) but no significant gain thereafter through T5 (P = .7). Predictors of low awareness included education less than a college degree (odds ratio [OR], 1.9; P = .02), longer time from diagnosis (OR, 1.03/year; P = .04), diagnosis of leukemia (OR, 2.1; P = .004), nonwhite race (OR, 2.8; P < .001), and risk for six or fewer complications (OR, 2.1; P = .002). Risk-based education in a survivorship clinic significantly increases awareness of personal health risk through three sessions, with saturation thereafter. Vulnerable populations with minimal gain in awareness identified in this study could inform targeted interventions. © 2015 by American Society of Clinical Oncology.

Pauci-immune glomerulonephritis is rare in African Americans (AA) and the clinical presentation and treatment outcomes of vasculitis have not been well described. We identified patients who were 2-92 years of age between 1983 and 2011 with a diagnosis of biopsy-proven pauci-immune glomerulonephritis (GN) at any point during their disease course. Comparing AA to Caucasian patients, we examined demographics, clinical features at presentation, treatment and outcomes of relapse, end-stage renal disease (ESRD), and death. Of the 672 patients, 75 were AA with the remainder being Caucasian. Compared to Caucasians, disease onset in AA was at an earlier age (52 vs. 57 years, p = 0.05) and was more often myeloperoxidase (MPO)-anti-neutrophil cytoplasmic antibody (ANCA) positive (71% vs. 54%, p = 0.01). AA patients had a shorter median time between onset of symptoms and biopsy compared to Caucasians [median (IQR): 0.23 (0.00, 1.22) months vs. 0.66 (0.00, 3.62) months, p = 0.003]. Median [Interquartile range (IQR)] follow-up in months was 28 (5, 52) in AA and 26 (10, 55) in Caucasian patients. Median estimated glomerular filtration rate was similar at presentation (21 vs. 22 ml/min/m(2)). Both groups had similar induction treatment regimens. There was less favorable treatment response among AA compared to Caucasians for initial treatment resistance (28% vs. 18%, p = 0.05) and complete remission (72% vs. 82%, p = 0.05). There were no differences in the number of renal relapses or number of deaths between the 2 groups. Overall, in multivariable analyses controlling for age, race, ANCA type, and entry serum creatinine, there were not differences by race in treatment response, renal relapse, ESRD, or death over the entire time of follow-up. AA patients with pauci-immune GN are younger and more often MPO-ANCA positive compared to Caucasians. Despite a shorter time to diagnosis for AA patients, there were no differences compared to Caucasians in treatment response, ESRD, renal relapse, or death rates by race over the entire duration of follow-up. © 2013 Published by Elsevier Inc.

Background The National Confidential Enquiry describes the epidemiology of children admitted to hospital with head injury. Method Children (<15 years old) who died or were admitted for >4 h with head injury were identified from 216 UK hospitals (1 September 2009 to 28 February 2010). Data were collected using standard proformas and entered on to a database. A descriptive analysis of the causal mechanisms, child demographics, neurological impairment, CT findings, and outcome at 72 h are provided. Results Details of 5700 children, median age 4 years (range 0–14.9 years), were analysed; 1093 (19.2%) were <1 year old, 3500 (61.4%) were boys. There was a significant association of head injury with social deprivation 39.7/100 000 (95% CI 37.0 to 42.6) in the least deprived first quintile vs. 55.1 (95% CI 52.1 to 58.2) in the most deprived fifth quintile (p<0.01). Twenty-four children died (0.4%). Most children were admitted for one night or less; 4522 (79%) had a Glasgow Coma Scale score of 15 or were Alert (on AVPU (Alert, Voice, Pain, Unresponsive)). The most common causes of head injury were falls (3537 (62.1%); children <5 years), sports-related incidents (783 (13.7%); median age 12.4 years), or motor vehicle accidents (MVAs) (401 (7.1%); primary-school-aged children). CT scans were performed in 1734 (30.4%) children; 536 (30.9%) were abnormal (skull fracture and/or intracranial injury or abnormality): 269 (7.6%) were falls, 82 (10.5%) sports related and 100 (25%). A total of 357 (6.2%) children were referred to social care because of child protection concerns (median age 9 months (range 0–14.9 years)). Conclusions The data described highlight priorities for targeted age-specific head injury prevention and have the potential to provide a baseline to evaluate the effects of regional trauma networks (2012) and National Institute of Health and Care Excellence (NICE) head injury guidelines (2014), which were revised after the study was completed.

Tendulkar, Rahul D., E-mail: tendulr@ccf.org; Hunter, Grant K.; Reddy, Chandana A.

Purpose: Men with high-risk prostate cancer have other competing causes of mortality; however, current risk stratification schema do not account for comorbidities. We aim to identify the causes of death and factors predictive for mortality in this population. Methods and Materials: A total of 660 patients with high-risk prostate cancer were treated with definitive high-dose external beam radiation therapy (≥74 Gy) and androgen deprivation (AD) between 1996 and 2009 at a single institution. Cox proportional hazards regression analysis was conducted to determine factors predictive of survival. Results: The median radiation dose was 78 Gy, median duration of AD was 6more » months, and median follow-up was 74 months. The 10-year overall survival (OS) was 60.6%. Prostate cancer was the leading single cause of death, with 10-year mortality of 14.1% (95% CI 10.7-17.6), compared with other cancers (8.4%, 95% CI 5.7-11.1), cardiovascular disease (7.3%, 95% CI 4.7-9.9), and all other causes (10.4%, 95% CI 7.2-13.6). On multivariate analysis, older age (HR 1.55, P=.002) and Charlson comorbidity index score (CS) ≥1 (HR 2.20, P<.0001) were significant factors predictive of OS, whereas Gleason score, T stage, prostate-specific antigen, duration of AD, radiation dose, smoking history, and body mass index were not. Men younger than 70 years of age with CS = 0 were more likely to die of prostate cancer than any other cause, whereas older men or those with CS ≥1 more commonly suffered non-prostate cancer death. The cumulative incidences of prostate cancer-specific mortality were similar regardless of age or comorbidities (P=.60). Conclusions: Men with high-risk prostate cancer are more likely to die of causes other than prostate cancer, except for the subgroup of men younger than 70 years of age without comorbidities. Only older age and presence of comorbidities significantly predicted for OS, whereas prostate cancer- and treatment-related factors did not.« less

Germline mutations in BRCA1 and BRCA2 (BRCA1/2) are related to an increased lifetime risk of developing breast and ovarian cancer. Although risk-reducing salpingo-oophorectomy reduces the risk of both cancers, loss of fertility is a major concern. A recent study suggested an association between BRCA1 mutation and occult primary ovarian insufficiency. The objective of the current study was to determine whether BRCA1/2 mutation carriers have an earlier onset of natural menopause compared with unaffected women. White carriers of the BRCA1/2 gene (n = 382) were identified within the Breast Cancer Risk Program Registry at the University of California at San Francisco and compared with non-clinic-based white women in northern California (n = 765). The 2 groups were compared with regard to median age at the time of natural menopause before and after adjustment for known risk factors, and the role of smoking within each group was examined using the Kaplan-Meier approach for unadjusted analyses and Cox proportional hazards regression analyses for adjusted analyses. The median age at the time of natural menopause in the BRCA1/2 carriers was significantly younger than among the unaffected sample (50 years vs 53 years; P < .001). The unadjusted hazard ratio for natural menopause when comparing BRCA1/2 carriers with unaffected women was 4.06 (95% confidence interval, 3.03-5.45) and was 3.98 (95% confidence interval, 2.87-5.53) after adjusting for smoking, parity, and oral contraceptive use. For BRCA1/2 carriers who were current heavy smokers (smoking ≥ 20 cigarettes/day), the median age at natural menopause was 46 years versus 49 years for nonsmokers (P = .027). The BRCA1/2 mutation was associated with a significantly earlier age at natural menopause, and heavy smoking compounded this risk. Because the relationship between menopause and the end of natural fertility is considered to be fixed, these findings suggest the risk of earlier infertility among BRCA1/2 carriers.

To assess the prevalence of early confluent/confluent white matter lesions (ec/cWMLs) in asymptomatic individuals aged ≥50 years and to identify associated clinical phenotypes. Cross-sectional analysis of 141 asymptomatic individuals aged ≥50 years assessed at an outpatient department in France. Brain magnetic resonance imaging was rated using the Fazekas scale. Age-adjusted odds ratios (ORs) and 95% confidence intervals were estimated using logistic models to investigate factors associated with ec/cWMLs; independent risk factors were identified by multivariate analysis. Median age was 63 years; 53.9% were women, 32.6% had hypertension, and 76.6% had ≥1 cardiovascular risk factors. The prevalence of ec/cWMLs was 26.2%. Apart from age, independent risk factors were family history of cardiovascular event (OR = 5.55; 1.13-27.32) and hypertension (2.47; 1.05-5.81). Patients with ec/cWMLs had lower cognitive dual-task walking speed (1.15; 0.98-1.40), MMSE (1.41; 1.06-1.89), and FAB scores (5.21; 1.49-19.84). The Scheltens score was independently associated with the WML severity score. ec/cWMLs are common in asymptomatic community-dwelling individuals aged ≥50 years. They are associated with cardiovascular risk factors, impairments in global and executive cognitive function, and Scheltens score elevation. © 2016 S. Karger AG, Basel.

Prevalence of skin sores and scabies in remote Australian Aboriginal communities remains unacceptably high, with Group A Streptococcus (GAS) the dominant pathogen. We aim to better understand the drivers of GAS transmission using mathematical models. To estimate the force of infection, we quantified the age of first skin sores and scabies infection by pooling historical data from three studies conducted across five remote Aboriginal communities for children born between 2001 and 2005. We estimated the age of the first infection using the Kaplan-Meier estimator; parametric exponential mixture model; and Cox proportional hazards. For skin sores, the mean age of the first infection was approximately 10 months and the median was 7 months, with some heterogeneity in median observed by the community. For scabies, the mean age of the first infection was approximately 9 months and the median was 8 months, with significant heterogeneity by the community and an enhanced risk for children born between October and December. The young age of the first infection with skin sores and scabies reflects the high disease burden in these communities.

The median maxillary labial frenum (MMLF) is a normal anatomic structure with inherent morphologic variations. This study sought to evaluate the prevalence of those variations in a diverse ethnic population and to educate practitioners about the prevalence of MMLF variations to prevent unnecessary biopsies. This study included adult, adolescent, and child patients at the Louisiana State University Health Science Center School of Dentistry. Among the 284 subjects examined, frenum normale was the most common frenum classification, followed by frenum with nodule and frenum with appendix. Most nodules were found in the intermediate third of the MMLF, while appendices were mainly found in the labial third. The prevalence of an appendix was significantly higher (P < 0.001) in Caucasians compared to African-Americans. The prevalence of nodules was marginally higher (P = 0.096) in Caucasians than in African-Americans. No other statistically significant differences were found with regard to ethnicity. Additionally, nodules and appendices on the MMLF were identified in all age groups, and may become more common with increasing age. The authors determined that variations of the MMLF are inherent and do not represent a pathologic condition, nor do they require biopsy for diagnostic purposes.

Orthodontic treatment of children/adolescents with special health care needs: an analysis of treatment length and clinical outcome

2014-01-01

Background The aim of this retrospective study was to analyse the treatment time and differences between the pre- and post-treatment peer assessment rating (PAR) index and aesthetic component (AC) of the index of orthodontic treatment need (IOTN) scores in children/adolescents with special health care needs (SHCNs), compared to non-special health care needs (NSHCNs) controls. Methods Based on certain inclusion and exclusion criteria, medical records of SHCNs and randomly selected NSHCNs controls at the Department of Orthodontics, University Hospital Muenster were analysed retrospectively for the treatment time, number of appointments, chair time (“moderate” or “considerable”), PAR scores, and AC scores. Sample size calculation, descriptive statistics, and explorative analyses were performed using the Mann–Whitney U Test. Results Twenty-nine children with SHCNs (21 boys, 9 girls; median age: 11 years, pre-treatment) and 29 children with NSHCNs (12 boys, 17 girls; median age: 12 years, pre-treatment) were enrolled in this study. The overall treatment time did not differ between the patient groups. However, more “considerable chair time” was needed for the SHCNs group compared to the control group (p < 0.05), whereas “moderate chair time” was more often needed in patients with NSHCNs (p = 0.001). The age of the patients at the first and last appointments showed significant statistical differences: children in the SHCNs group commenced orthodontic treatment earlier, by a median of 1 year, compared to children in the NSHCNs group. The SHCNs group had significantly higher pre- and post-treatment PAR scores (median 21/median 6) and AC scores (median 9/median 3) compared to NSHCNs patients (PAR: median 17/median 0; AC: median 5/median 1). However, the overall treatment time and the overall PAR and AC score reduction did not differ significantly between the SHCNs and NSHCNs groups. Conclusions While the overall treatment time and number of appointments did not differ, the overall chair time was higher in the SHCNs group. The pre- and post-treatment PAR and AC scores were significantly higher in the SHCNs group. PMID:24915851

To identify clinical or demographic variables that influence long-term mortality, as well as in-hospital mortality, with a particular focus on the effects of age. Cervical spine fractures with or without spinal cord injury (SCI) disproportionately impact the elderly who constitute an increasing percentage of the US population. We analyzed data collected for 10 years at a state-designated level I trauma center to identify variables that influenced in-hospital and long-term mortality among elderly patients with traumatic cervical spine fracture with or without SCI. Acute in-hospital mortality was determined from hospital records and long-term mortality within the study period (2003-2013) was determined from the National Death Index. Univariate and multivariate regression analyses were used to identify factors influencing survival. Data from patients (N = 632) with cervical spine fractures were analyzed, the majority (66%) of whom were geriatric (older than age 64). Most patients (62%) had a mild/moderate injury severity score (ISS; median, interquartile range: 6, 5). Patients with SCI had significantly longer lengths of stay (14.1 days), days on a ventilator (3.5 days), and higher ISS (14.9) than patients without SCI ( P < .0001 for all). Falls were the leading mechanism of injury for patients older than age 64. Univariate analysis identified that long-term survival decreased significantly for all patients older than age 65 (hazard ratio [HR]: 1.07; P < .0001). Multivariate analysis demonstrated age (HR: 1.08; P < .0001), gender (HR: 1.60; P < .0007), and SCI status (HR: 1.45, P < .02) significantly influenced survival during the study period. This study identified age, gender, and SCI status as significant variables for this study population influencing long-term survival among patients with cervical spine fractures. Our results support the growing notion that cervical spine injuries in geriatric patients with trauma may warrant additional research.

Population-based estimates of the incidence and prognosis of brain metastases at diagnosis of breast cancer are lacking. To characterize the incidence proportions and median survivals of patients with breast cancer and brain metastases at the time of cancer diagnosis. Patients with breast cancer and brain metastases at the time of diagnosis were identified using the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute. Data were stratified by subtype, age, sex, and race. Multivariable logistic and Cox regression were performed to identify predictors of the presence of brain metastases at diagnosis and factors associated with all-cause mortality, respectively. For incidence, we identified a population-based sample of 238 726 adult patients diagnosed as having invasive breast cancer between 2010 and 2013 for whom the presence or absence of brain metastases at diagnosis was known. Patients diagnosed at autopsy or with an unknown follow-up were excluded from the survival analysis, leaving 231 684 patients in this cohort. Incidence proportion and median survival of patients with brain metastases and newly diagnosed breast cancer. We identified 968 patients with brain metastases at the time of diagnosis of breast cancer, representing 0.41% of the entire cohort and 7.56% of the subset with metastatic disease to any site. A total of 57 were 18 to 40 years old, 423 were 41 to 60 years old, 425 were 61-80 years old, and 63 were older than 80 years. Ten were male and 958 were female. Incidence proportions were highest among patients with hormone receptor (HR)-negative human epidermal growth factor receptor 2 (HER2)-positive (1.1% among entire cohort, 11.5% among patients with metastatic disease to any distant site) and triple-negative (0.7% among entire cohort, 11.4% among patients with metastatic disease to any distant site) subtypes. Median survival among the entire cohort with brain metastases was 10.0 months. Patients with HR-positive HER2-positive subtype displayed the longest median survival (21.0 months); patients with triple-negative subtype had the shortest median survival (6.0 months). The findings of this study provides population-based estimates of the incidence and prognosis for patients with brain metastases at time of diagnosis of breast cancer. The findings lend support to consideration of screening imaging of the brain for patients with HER2-positive or triple-negative subtypes and extracranial metastases.

Biomaterial research has made available a biologically derived fully resorbable poly-4-hydroxybutyrate (P4HB) mesh for use in ventral and incisional hernia repair (VIHR). This study evaluates outcomes of patients undergoing VIHR with P4HB mesh. An IRB-approved prospective pilot study was conducted to assess clinical and quality of life (QOL) outcomes for patients undergoing VIHR with P4HB mesh. Perioperative characteristics were defined. Clinical outcomes, employment status, QOL using 12-item short form survey (SF-12), and pain assessments were followed for 24 months postoperatively. 31 patients underwent VIHR with bioresorbable mesh via a Rives-Stoppa approach with retrorectus mesh placement. The median patient age was 52 years, median body mass index was 33 kg/m 2 , and just over half of the patients were female. Surgical site occurrences occurred in 19% of patients, most of which were seroma. Hernia recurrence rate was 0% (median follow-up = 414 days). Patients had significantly improved QOL at 24 months compared to baseline for SF-12 physical component summary and role emotional (p < 0.05). Ventral hernia repair with P4HB bioresorbable mesh results in favorable outcomes. Early hernia recurrence was not identified among the patient cohort. Quality of life improvements were noted at 24 months versus baseline for this cohort of patients with bioresorbable mesh. Use of P4HB mesh for ventral hernia repair was found to be feasible in this patient population. (ClinicalTrials.gov Identifier: NCT01863030).

Retrospective cohort study. To describe the demographics, clinical presentation, and functional outcomes of fibrocartilaginous embolic myelopathy (FCEM). Academic inpatient rehabilitation unit in the midwestern United States. We retrospectively searched our database to identify patients admitted between January 1, 1995 and March 31, 2016, with a high probability of FCEM. Demographic, clinical, and functional outcome measures, including Functional Independence Measure (FIM) information was obtained by chart review. We identified 31 patients with findings suggestive of FCEM (52% male), which was 2% of the nontraumatic spinal cord injury population admitted to inpatient rehabilitation. The age distribution was bimodal, with peaks in the second and sixth-to-seventh decades. The most common clinical presentation was acute pain and rapid progression of neurologic deficits consistent with a vascular myelopathy. Only three patients (10%) had FCEM documented as a diagnostic possibility. Most patients had paraplegia and neurologically incomplete injuries and were discharged to home. Nearly half of the patients required no assistive device for bladder management at discharge, but most were discharged with medications for bowel management. Median FIM walking locomotion score for all patients was 5, but most patients were discharged using a wheelchair for primary mobility. Median motor FIM subscale score was 36 at admission and 69 at discharge, with a median motor efficiency of 1.41. FCEM may be underdiagnosed and should be considered in those with the appropriate clinical presentation, because their functional outcomes may be more favorable than those with other causes of spinal cord infarction.

Background. To improve our understanding of risk factors, management, diagnosis, and outcomes associated with histoplasmosis after solid organ transplant (SOT), we report a large series of histoplasmosis occurring after SOT. Methods. All cases of histoplasmosis in SOT recipients diagnosed between 1 January 2003 and 31 December 2010 at 24 institutions were identified. Demographic, clinical, and laboratory data were collected. Results. One hundred fifty-two cases were identified: kidney (51%), liver (16%), kidney/pancreas (14%), heart (9%), lung (5%), pancreas (2%), and other (2%). The median time from transplant to diagnosis was 27 months, but 34% were diagnosed in the first year after transplant. Twenty-eight percent of patients had severe disease (requiring intensive care unit admission); 81% had disseminated disease. Urine Histoplasma antigen detection was the most sensitive diagnostic method, positive in 132 of 142 patients (93%). An amphotericin formulation was administered initially to 73% of patients for a median duration of 2 weeks; step-down therapy with an azole was continued for a median duration of 12 months. Ten percent of patients died due to histoplasmosis with 72% of deaths occurring in the first month after diagnosis; older age and severe disease were risk factors for death from histoplasmosis. Relapse occurred in 6% of patients. Conclusions. Although late cases occur, the first year after SOT is the period of highest risk for histoplasmosis. In patients who survive the first month after diagnosis, treatment with an amphotericin formulation followed by an azole for 12 months is usually successful, with only rare relapse. PMID:24046304

Flea-borne (murine) typhus is a global rickettsiosis caused by Rickettsia typhi. Although flea-borne typhus is no longer nationally notifiable, cases are reported for surveillance purposes in a few U.S. states. The infection is typically self-limiting, but may be severe or life-threatening in some patients. We performed a retrospective review of confirmed or probable cases of fatal flea-borne typhus reported to the Texas Department of State Health Services during 1985–2015. When available, medical charts were also examined. Eleven cases of fatal flea-borne typhus were identified. The median patient age was 62 years (range, 36–84 years) and 8 (73%) were male. Patients presented most commonly with fever (100%), nausea and vomiting (55%), and rash (55%). Respiratory (55%) and neurologic (45%) manifestations were also identified frequently. Laboratory abnormalities included thrombocytopenia (82%) and elevated hepatic transaminases (63%). Flea or animal contact before illness onset was frequently reported (55%). The median time from hospitalization to administration of a tetracycline-class drug was 4 days (range, 0–5 days). The median time from symptom onset to death was 14 days (range, 1–34 days). Flea-borne typhus can be a life-threatening disease if not treated in a timely manner with appropriate tetracycline-class antibiotics. Flea-borne typhus should be considered in febrile patients with animal or flea exposure and respiratory or neurologic symptoms of unknown etiology. PMID:28500797

Preserving patient dignity is a sentinel premise of palliative care. This study was conducted to gain a better understanding of factors influencing preservation of dignity in the last chapter of life. We conducted an open-ended written survey of 100 multidisciplinary providers (69% response rate) and responses were categorized to identify 2 main themes, 5 subthemes, and 10 individual factors that were used to create the preservation of dignity card-sort tool (p-DCT). The 10-item rank order tool was administered to a cohort of community dwelling Filipino Americans (n = 140, age mean = 61.3, 45% male and 55% female). A Spearman correlation matrix was constructed for all the 10 individual factors as well as the themes and subthemes based on the data generated by the subjects. The individual factors were minimally correlated with each other indicating that each factor was an independent stand-alone factor. The median, 25th and 75th percentile ranks were calculated and "s/he has self-respect" (intrinsic theme, self-esteem subtheme) emerged as the most important factor (mean rank 3.0 and median rank 2.0) followed by "others treat her/him with respect" (extrinsic theme, respect subtheme) with a mean rank = 3.6 and median = 3.0. The p-DCT is a simple, rank order card-sort tool that may help clinicians identify patients' perceptions of key factors influencing the preservation of their dignity in the last chapter of life.

Background Cholangiocarcinoma is the second most frequent primitive liver malignancy and is responsible for 3% of the malignant gastrointestinal neoplasms. The aims of this study were to determine the association of serum levels of CA 19-9 at diagnosis with other clinical data and serum liver function tests and to identify possible factors that influence the survival rates during follow-up. Methods Retrospective observational study of 89 patients with a diagnosis of cholangiocarcinoma followed at the Department of Gastroenterology during 5 years. Statistical analyses were performed using SPSS version 20.0. Results Patients were followed up for a median time of 127 days (IQR: 48–564), and the median age at diagnosis was 71.0 years (IQR: 62.0–77.5). The median survival rate was 14.0 months (IQR: 4.3–23.7), and the mortality rate was 79%. Patients with CA 19-9 levels ≥103 U/L had lower albumin levels and higher levels of alanine aminotransferase and γ-glutamyltransferase. CA 19-9 levels ≥103 U/L were associated with a higher probability of metastization (p = 0.001) and lower rates of treatment with curative intent (p = 0.024). In a multivariate analysis, CA 19-9 levels <103 U/L and surgery were independent predictors of survival. Conclusion Predictive factors for overall survival were identified, namely presence of metastasis, surgery, and chemotherapy. CA 19-9 levels ≥103 U/L were predictive factors for survival and metastization. PMID:28848795

Glance legibility studies conducted at the TTI Proving Grounds examined the legibility of three commercially available LCS with respect to symbol, signal type, subject gender, and subject age. Also, the effect of ambient light conditions was also explored. Symbols on all three signals resulted in median glance legibility distances of 304.8 meters (1000 feet) or greater, whereas the 85th percentile glance legibility distance was 213.4 meters (700 feet) or greater. Of the various factors examined, only the age of the subject significantly influenced legibility distances. In general, drivers 65 years and older had to be 91.5 to 198.1 meters (300more » to 650 feet) closer to the signals to correctly identify the symbols being displayed than drivers aged 16 to 44 years.« less

The purpose of this study was to evaluate whether the sample of older adults in a home fire safety (HFS) study captured participants living in the areas at highest risk for fire occurrence. The secondary aim was to identify high risk areas to focus future HFS interventions. Geographic information systems software was used to identify census tracts where study participants resided. Census data for these tracts were compared with participant data based on seven risk factors (ie, age greater than 65 years, nonwhite race, below high school education, low socioeconomic status, rented housing, year home built, home value) previously identified in a fire risk model. The distribution of participants and census tracts among risk categories determined how well higher risk census tracts were sampled. Of the 46 census tracts where the HFS intervention was implemented, 78% (n = 36) were identified as high or severe risk according to the fire risk model. Study participants' means for median annual family income (P < .0001) and median home value (P < .0001) were significantly lower than the census tract means (n = 46), indicating participants were at higher risk of fire occurrence. Of the 92 census tracts identified as high or severe risk in the entire county, the study intervention was implemented in 39% (n = 36), indicating 56 census tracts as potential areas for future HFS interventions. The Geographic information system-based fire risk model is an underutilized but important tool for practice that allows community agencies to develop, plan, and evaluate their outreach efforts and ensure the most effective use of scarce resources.

and sulfur hexafluoride from 288 wells and springs in parts of the Santa Fe Group aquifer system. The surface-water data collected as part of this study include monthly measurements of major- and minor-element chemistry (30 elements), oxygen-18 and deuterium content of water, chlorofluorocarbons, and tritium content at 14 locations throughout the basin. Additional data include stable isotope analyses of precipitation and of ground water from City of Albuquerque production wells collected and archived from the early 1980?s, and other data on the chemical and isotopic composition of air, unsaturated zone air, plants, and carbonate minerals from throughout the basin. The data were used to identify 12 sources of water to the basin, map spatial and vertical extents of ground-water flow, map water chemistry in relation to hydrogeologic, stratigraphic, and structural properties of the basin, determine radiocarbon ages of ground water, and reconstruct paleo-environmental conditions in the basin over the past 30,000 years. The data indicate that concentrations of most elements and isotopes generally parallel the predominant north to south direction of ground-water flow. The radiocarbon ages of dissolved inorganic carbon in ground water range from modern (post-1950) to more than 30,000 years before present, and appear to be particularly well defined in the predominantly siliciclastic aquifer system. Major sources of water to the basin include (1) recharge from mountains along the north, east and southwest margins (median age 5,000-9,000 years); (2) seepage from the Rio Grande and Rio Puerco (median age 4,000-8,000 years), and from Abo and Tijeras Arroyos (median age 3,000-9,000 years); (3) inflow of saline water along the southwestern basin margin (median age 20,000 years); and (4) inflow along the northern basin margin that probably represents recharge from the Jemez Mountains during the last glacial period (median age 20,000 years). Water recharged from the Jemez Mountains during the last glacial period occurs at the water table in the central part of the basin and beneath younger recharge along the Rio Grande and the northern mountain front. In some parts of the basin, boundaries between hydrochemical zones appear to be near major faults that may affect ground-water flow. However, in other parts of the basin, such as along the east side of Albuquerque near the Sandia Fault zone, ground-water flow appears to be unaffected by major faults. Upward leakage of saline water occurs along some faults and can be a source of salinity and elevated arsenic concentrations in some ground water. A trough in the modern and predevelopment water table west of Albuquerque is centered along a zone of predominantly late Pleistocene age water through the center of the basin and is flanked and overlain along the trough boundary by water that infiltrated from the Rio Puerco on the west and the Rio Grande to the east. It is suggested that the groundwater trough is a relatively recent transient feature of the Santa Fe Group aquifer system. At Albuquerque, a distinct north-south boundary in deuterium content of ground water marks the division between recharge from the eastern mountain front and that from the Rio G

To determine the outcomes of Canadian children with biliary atresia. Health records of infants born in Canada between January 1, 1985 and December 31, 1995 (ERA I) and between January 1, 1996 and December 31, 2002 (ERA II) who were diagnosed with biliary atresia at a university center were reviewed. 349 patients were identified. Median patient age at time of the Kasai operation was 55 days. Median age at last follow-up was 70 months. The 4-year patient survival rate was 81% (ERA I = 74%; ERA II = 82%; P = not significant [NS]). Kaplan-Meier survival curves for patients undergoing the Kasai operation at age < or = 30, 31 to 90, and > 90 days showed 49%, 36%, and 23%, respectively, were alive with their native liver at 4 years (P < .0001). This difference continued through 10 years. The 2- and 4-year post-Kasai operation native liver survival rates were 47% and 35% for ERA I and 46% and 39% for ERA II (P = NS). A total of 210 patients (60%) underwent liver transplantation; the 4-year transplantation survival rate was 82% (ERA I = 83%, ERA II = 82%; P = NS). This is the largest outcome series of North American children with biliary atresia at a time when liver transplantation was available. Results in each era were similar. Late referral remains problematic; policies to ensure timely diagnosis are required. Nevertheless, outcomes in Canada are comparable to those reported elsewhere.

Severe idiopathic tricuspid regurgitation (TR) occurs in the aged, but the mechanism of TR is unclear and there is little information on atrial abnormalities associated with this condition. This study retrospectively analyzed patients with severe functional TR presenting with common clinical features suggesting a distinct syndrome. Eleven patients with severe functional TR were identified by reviewing the records of 16,235 consecutive patients. All patients had undergone clinical evaluation including echocardiography, electrocardiography and laboratory data. The median age of patients with severe functional TR was 78 years. All had a long-standing history of atrial fibrillation (median duration, 23 years). Clinical features are characterized by severe functional TR due to annular dilation, markedly dilated right atrium, episodes of right-sided heart failure, absent or diminished fibrillation waves on electrocardiogram, bradycardia probably due to partial atrial standstill, and decreased atrial natriuretic peptide secretion. During long-term follow up, right atrial size progressively increased in association with worsening TR. Severe functional TR occurs with long-standing atrial fibrillation and causes right-sided heart failure. The TR is caused by tricuspid valve systolic coaptation loss due to tricuspid annular dilation associated with atrial dilation. This condition is associated with atrial abnormalities, such as atrial standstill and impaired atrial natriuretic peptide secretion. We propose that atrial remodeling associated with atrial fibrillation is central to the occurrence of the syndrome.

Purpose: Atypical teratoid/rhabdoid tumor (AT/RT) is an uncommon and aggressive tumor that often affects infants. Irradiation improves survival but has traditionally been avoided in patients under the age of 3 due to the increasing risk of neurocognitive side effects. We report the first cohort of AT/RT patients treated with proton therapy. Methods and Materials: All patients with AT/RT treated at Massachusetts General Hospital (MGH) Frances H. Burr Proton Beam Therapy Benter between July 2004 and November 2011 were included in this study. All patients were treated with 3-dimensional conformal proton therapy (3D-CPT). Results: Ten consecutive patients of a median 2.3more » years of age and with a median follow-up of 27.3 months (range, 11.3-99.4 months) were identified. Two patients suffered distant relapse; 1 patient was successfully treated with involved field irradiation and chemotherapy, while the second patient died of disease. At last follow-up, 9 patients were alive without evidence of disease. Proton radiation demonstrated increasing sparing of the cerebrum, temporal lobe, cochlea, and hypothalamus. Conclusions: Initial clinical outcomes with proton therapy are favorable. The advantages of proton therapy are particularly suited to the treatment of AT/RT, a tumor that often requires irradiation treatment at an age when avoiding irradiation to healthy tissues is most desirable.« less

To evaluate the prevalence of malnutrition and its impact on mortality, functional decline and cognitive impairment among elder residents in long-term care settings. A prospective cohort study. Two veteran homes in Taiwan. A total of 1,248 male residents aged equal or more than 65 years. Charlson's comorbidity index (CCI), Minimum data set (MDS), resident assessment protocols (RAP), Activity of daily living-Hierarchy scale, Cognitive Performance Scale, MDS Social engagement scale. The mean age of participants is 83.1 ± 5.1 years, and the prevalence of malnutrition was 6.1%. Inadequate dietary content (57.9%) and unintentional weight loss (31.6%) account for the majority of malnutrition identified by MDS tool. Higher 18-month mortality rate (25% vs. 14.2%), higher baseline CCI (median 1 vs. 0), and higher baseline sum of RAP triggers (median 8.5 vs. 5) were noted among residents with malnutrition. Furthermore, malnutrition was shown predictive for functional decline (OR: 3.096, 95% CI: 1.715-5.587) and potential cognitive improvement (OR: 2.469, 95% CI: 1.188-5.128) among survivors after adjustment for age, body mass index and CCI. Malnutrition among elder men residing in veteran homes was associated with multimorbidities and higher care complexity, and was predictive for mortality and functional decline.

Hospital-acquired Clostridium difficile infection (CDI) may cause life-threatening colitis for children with cancer, making identification of risk factors important. We described characteristics of pediatric cancer patients with primary and recurring CDI, and evaluated potential risk factors. Among 189 cancer patients, 51 cases (27%) of CDI and 94 matched controls of cancer patients without CDI were analyzed. Multivariable logistic regression was used to evaluate the association between CDI and several potential risk factors. Median age of CDI cases was lower (3.3 y; 0.60 to 16.2) than controls (7.7 y; 0.4 to 20.5). Median duration of neutropenia before CDI was longer for CDI cases (10.0 d; 0.0 to 30.0) compared with duration calculated from reference date in controls (6.0 d; 0.0 to 29.0). Multivariable analysis showed that older age was associated with reduced risk (≥7 vs. 0 to 3 y, odds ratio=0.11; 95% confidence interval, 0.02-0.54), and prolonged neutropenia was associated with increased risk (odds ratio=1.11; 95% confidence interval, 1.01-1.22). CDI recurred in 26% of cases. Younger age and prolonged neutropenia were risk factors for CDI in children with cancer. Increasing awareness to these risk factors will help to identify opportunities for CDI prevention in cancer patients.

We aimed to investigate the incidence and mortality of herpes simplex encephalitis (HSE) in a nationwide cohort. From the Danish National Patient Registry, we identified all adults hospitalised with a first-time diagnosis of HSE in Denmark during 2004-2014. The HSE diagnoses were verified using medical records and microbiological data. Patients were followed for mortality through the Danish Civil Registry System. We estimated age-standardised incidence rates of HSE and 30-day, 60-day, and 1-year cumulative mortality. Furthermore, we assessed whether calendar year, age, gender, level of comorbidity, virus type, and department type was associated with HSE mortality. We identified a total of 230 cases of HSE. Median age was 60.7 years (interquartile range: 49.3-71.6). The overall incidence rate was 4.64 cases per million population per year (95% confidence interval: 4.06-5.28). The cumulative mortality within 30 days, 60 days, and 1 year of the HSE admission was 8.3%, 11.3%, and 18.6%, respectively. Advanced age and presence of comorbidity were associated with increased 60-day and 1-year mortality. This nationwide study of verified HSE found a higher incidence than reported in previous nationwide studies. Presence of comorbidity was identified as a novel adverse prognostic factor. Mortality rates following HSE remain high. Copyright © 2016 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

The study aimed to verify the role of parity, age and bowel function in the pathogenesis of anorectocele. A cross-sectional study was conducted regarding age, obstetrical history, Cleveland Clinic Constipation Score (CCCS), cinedefecography and anal manometry findings. Forty-five adult women complaining of obstructed defecation were evaluated; the median age was 46 years and median CCCS, 13. Fifteen patients were nulliparous and 23 multiparous (median parity 2). Eighteen had a history of episiotomy, fourteen delivered large babies and two had forceps-assisted delivery. Statistical analysis was performed using Spearman's correlation test and Fisher's exact test. Anal hypertonia was found in 14 (31.1%) patients, anal hypotonia in eight (17.8%), anismus in 13 (28.9%) and anorectoceles in 34 (75.6%) [median size 2.8 cm (0-6.4)]. There were no correlations between anorectocele and anal hypertonia (P = 0.7171), anismus (P = 0.4666), parity comparing nulliparous and multiparous patients (P = 1.000), episiotomy (P = 1.0000), forceps assistance (P = 1.0000), delivery of a large baby (P = 1.0000) anal resting pressure (P = 0.0883), anal voluntary pressure (P = 0.7327), parity (P = 0.4987) and age (P = 0.8603). There were correlations between anorectocele and the CCCS (P = 0.0082) and anal hypotonia (P = 0.0141). Anorectocele is not correlated with parity, age, episiotomy, delivery of a large baby and anismus. It was more frequent in patients with severe constipation and less common in patients with anal hypotonia.

The objective of our study was to use proton MR spectroscopy (MRS) to quantitatively evaluate bone marrow infiltration by measuring the fat fraction (FF) and to compare the FF with semiquantitative bone marrow MRI scores and clinical status in children treated for type 1 Gaucher disease (GD). Over a 2-year period, we prospectively evaluated 10 treated GD patients (six males, four females; median age, 15.1 years) and 10 healthy age-matched control subjects (five males, five females; median age, 15.3 years) using 3-T proton MRS of L5 and the femoral neck. Water and lipid AUCs were measured to calculate the FF. Two blinded pediatric musculoskeletal radiologists performed a semiquantitative analysis of the conventional MR images using the bone marrow burden score and modified Spanish MRI score. We evaluated symptoms, spleen and liver volumes, platelet levels, hemoglobin levels, and bone complications. In the femur, the FF was higher in the control subjects (median, 0.71) than the GD patients (0.54) (p = 0.02). In L5, the difference in FF--higher FF in control subjects (0.37) than in GD patients (0.26)--was not significant (p = 0.16). In both groups and both regions, the FF increased with patient age (p < 0.02). Semiquantitative scores showed no differences between control subjects and treated GD patients (p > 0.11). Eight of 10 GD patients were asymptomatic and two had chronic bone pain. The median age of patients at symptom onset was 4.0 years, the median age of patients at the initiation of enzyme replacement therapy was 4.3 years, and the median treatment duration was 10.2 years. Hemoglobin level, platelet count, and liver volume at MRI were normal. Mean pretreatment spleen volume (15.4-fold above normal) decreased to 2.8-fold above normal at the time of MRI (p = 0.01). Proton MRS detected FF differences that were undetectable using conventional MRI; for that reason, proton MRS can be used to optimize treatment of GD patients.

Genomic profiling of cell-free circulating tumor DNA (ctDNA) is a potential alternative to repeat invasive biopsy in patients with advanced cancer. We report the first real-world cohort of comprehensive genomic assessments of patients with non-small-cell lung cancer (NSCLC) in a Chinese population. We performed a retrospective analysis of patients with advanced or metastatic NSCLC whose physician requested ctDNA-based genomic profiling using the Guardant360 platform from January 2016 to June 2017. Guardant360 includes all 4 major types of genomic alterations (point mutations, insertion-deletion alterations, fusions, and amplifications) in 73 genes. Genomic profiling was performed in 76 patients from Hong Kong during the 18-month study period (median age, 59.5 years; 41 men and 35 women). The histologic types included adenocarcinoma (n = 10), NSCLC, not otherwise specified (n = 58), and squamous cell carcinoma (n = 8). In the adenocarcinoma and NSCLC, not otherwise specified, combined group, 62 of the 68 patients (91%) had variants identified (range, 1-12; median, 3), of whom, 26 (42%) had ≥ 1 of the 7 National Comprehensive Cancer Network-recommended lung adenocarcinoma genomic targets. Concurrent detection of driver and resistance mutations were identified in 6 of 13 patients with EGFR driver mutations and in 3 of 5 patients with EML4-ALK fusions. All 8 patients with squamous cell carcinoma had multiple variants identified (range, 1-20; median, 6), including FGFR1 amplification and ERBB2 (HER2) amplification. PIK3CA amplification occurred in combination with either FGFR1 or ERBB2 (HER2) amplification or alone. Genomic profiling using ctDNA analysis detected alterations in most patients with advanced-stage NSCLC, with targetable aberrations and resistance mechanisms identified. This approach has demonstrated its feasibility in Asia. Copyright © 2018 Elsevier Inc. All rights reserved.

Aim To explore the appropriateness of applying a detailed assessment of general movements (GMs) and characterise the relationship between global and detailed assessment. Method The analysis was based on 783 video-recordings of 233 infants (79 females) who had been videoed from 27 to 45 weeks postmenstrual age. Apart from assessing the global GM categories (normal, poor repertoire [PR], cramped-synchronised [CS] or chaotic GMs), we scored the amplitude, speed, spatial range, proximal and distal rotations, onset and offset, tremulous and cramped components of the upper and lower extremities. Applying the optimality concept, the maximum GM optimality score of 42 indicates the optimal performance. Results GM optimality scores differentiated between normal GMs (Median=39; P75=41, P25=37); PR GMs (Median=25; P75=29, P25=22), and CS GMs (Median=12; P75=14, P25=10; p<0.01). The optimality score for chaotic GMs (mainly occurring at late preterm age) was similar to those for CS GMs (Median=14; P75=17, P25=12). Short-lasting tremulous movements occurred from very preterm age to postterm age across all GM categories, including normal GMs. The detailed score at postterm age was slightly lower compared to the scores at preterm and term age for both normal (p=0.02) and PR GMs (p<0.01). Interpretation Further research might demonstrate that the GM optimality score provides a solid base for the prediction of improvement vs. deterioration within an individual GM trajectory.

Recommended margins for thick cutaneous melanoma (Breslow thickness >4 mm; T4) have decreased over recent decades. Optimal margins and the role of sentinel node biopsy (SNB) in thick head and neck melanoma remain controversial. A single-center review was conducted of patients treated between 2002 and 2012 assessing the impact of excision margins and sentinel lymph node status on locoregional recurrence and melanoma-specific survival (MSS). One hundred eight patients were identified. Median age was 71.1 years and median Breslow thickness was 6.0 mm. Median follow-up was 40 months. Locoregional recurrence occurred in 27% and there was no significant reduction in recurrence with margins ≥2 cm (p = .17). Increasing margins did not improve survival (p = .58). Fifty-nine patients (55%) underwent SNB, of which 27% were positive. There was a trend toward longer survival for patients who were sentinel lymph node-negative (p = .097). Wider margins do not significantly improve locoregional recurrence or MSS. Sentinel lymph node involvement reflects a poor prognosis. © 2016 Wiley Periodicals, Inc.

The objectives are to analyze the outcomes of fetal interventions for fetal limb abnormalities associated with amniotic band syndrome (ABS), to compare the outcome with the known natural history, and to establish selection criteria for fetal intervention. In a Medline search, six cases of prenatal fetoscopic interventions for ABS were found. An unpublished case was added. Review of the seven cases of treated ABS in utero suggests that abnormal, but present blood flow at Doppler distal to the area constricted by the band may optimally identify cases suitable for fetal surgery. We propose a prenatal classification in stages of cases of ABS based on ultrasound and Doppler findings. Premature rupture of membranes (PROM) occurred in five patients (71%). The median gestational age (GA) at delivery was 34.8 weeks (range 32 to 39). The median time between procedure and PROM was 6 weeks (range 4 days to 14.3 weeks). The median time between procedure and delivery was 11.8 weeks (range 5-17). The use of a uniform prenatal classification of cases of ABS may allow a more precise correlation of prenatal findings and postnatal outcome. (c) 2009 John Wiley & Sons, Ltd.

To learn whether an antecedent hematologic disorder (AHD) is associated with additional risk in patients with therapy-related acute myeloid leukemia (t-AML). We reviewed data of 301 patients with newly diagnosed t-AML who sought care from January 2000 to January 2014 (183 t-AML without AHD, 118 t-AML with AHD). Overall, median follow-up was 44 months. The primary malignancy was non-Hodgkin lymphoma in 92 (31%), breast cancer in 80 (27%), and prostate cancer in 49 (16%). Median relapse-free survival (RFS) in t-AML without or with AHD was 10 months and 29 months, respectively (P = .032); median overall survival (OS) was 8 months and 8 months, respectively (P = .53). Multivariate analysis for OS identified older age, poor performance status, thrombocytopenia, nonfavorable cytogenetics, and lack of response as adverse factors. The favorable-risk cohort had better RFS and OS compared to the outcomes of patients in the intermediate- and adverse-risk cohorts; the RFS and OS did not differ between intermediate- and adverse-risk cohorts. The presence of AHD did not affect OS. Copyright © 2016 Elsevier Inc. All rights reserved.

When retained hemothorax occurs, video-assisted thoracoscopy or thoracotomy is performed, but recently, tissue plasminogen activator (tPA) has been used. This study evaluated intrapleural tPA use for retained traumatic hemothoraces. A retrospective review was conducted of trauma patients treated with intrapleural tPA for retained hemothorax. Data included demographics, past medical and surgical histories, injury details, treatment details, and outcomes. Seven patients (median age = 47 years, male = 6, blunt trauma = 6) met study criteria. All patients received a chest tube. Six patients later received computed tomography-guided drains for tPA infusion. Number of tPA treatments per patient varied from 1 to 5. Median total tPA dosage was 24 mg. Median time from injury to chest tube placement was 11 days and from chest tube placement to first tPA treatment was 4 days. No patients required a video-assisted thoracoscopy; however, 1 patient required thoracotomy. There were no deaths or bleeding complications attributed to intrapleural tPA. Although future studies are needed to identify optimum treatment guidelines, intrapleural tPA appears to be a safe and efficacious treatment option. Copyright © 2014 Elsevier Inc.

To evaluate unmet clinical need in unselected hypertrophic cardiomyopathy (HCM) patients to determine the risk of a wide range of subsequent cardiovascular disease endpoints and safety endpoints relevant for trial design. Population based cohort (CALIBER, linked primary care, hospital and mortality records in England, period 1997-2010), all people diagnosed with HCM were identified and matched by age, sex and general practice with ten randomly selected people without HCM. Random-effects Poisson models were used to assess the associations between HCM and cardiovascular diseases and bleeding. Among 3,290,455 eligible people a diagnosis of hypertrophic cardiomyopathy was found in 4 per 10,000. Forty-one percent of the 1,160 individuals with hypertrophic cardiomyopathy were women and the median age was 57 years. The median follow-up was 4.0 years. Compared to general population controls, people with HCM had higher risk of ventricular arrhythmia (incidence rate ratio = 23.53, [95% confidence interval 12.67-43.72]), cardiac arrest or sudden cardiac death (6.33 [3.69-10.85]), heart failure (4.31, [3.30-5.62]), and atrial fibrillation (3.80 [3.04-4.75]). HCM was also associated with a higher incidence of myocardial infarction ([MI] 1.90 [1.27-2.84]) and coronary revascularisation (2.32 [1.46-3.69]).The absolute Kaplan-Meier risks at 3 years were 8.8% for the composite endpoint of cardiovascular death or heart failure, 8.4% for the composite of cardiovascular death, stroke or myocardial infarction, and 1.5% for major bleeding. Our study identified major unmet need in HCM and highlighted the importance of implementing improved cardiovascular prevention strategies to increase life-expectancy of the contemporary HCM population. They also show that national electronic health records provide an effective method for identifying outcomes and clinically relevant estimates of composite efficacy and safety endpoints essential for trial design in rare diseases.

From 1992 to 1996, 95 patients with tetanus were treated in the Chair and Department of Infectious Diseases in Cracow. Most of them came from rural area, and at old age (median 68 years). Small, trivial skin injuries were the most often identified portal of entry. Only few patients applied to doctor after injury for prophylaxis against tetanus. The authors emphasise that small skin injuries, which may be portal of entry for tetanus, should not be left abandoned.

The routine use of recombinant human granulocyte-colony stimulating factor (rhG-CSF) after high-dose chemotherapy and autologous stem cell transplantation (auto-SCT) is associated with increased costs. We prospectively explored a strategy that used prophylactic delayed filgrastim only in patients with risk factors. This sequential cohort analysis compared the outcomes of consecutive patients, treated on the risk-adapted protocol (RAP) (risk factors: prior febrile neutropenia; age >60 years; and CD34+ cell infused dose of <2 × 10(6/)/kg), who received filgrastim from day +6 after auto-SCT with a historical cohort (historical day-1 cohort [HD1]), who received filgrastim from day +1. Eighty-two patients were treated in the RAP cohort and compared with 115 patients in the HD1 cohort. There were no differences in median age (55 years) or median CD34+ cell dose (5.21 × 10(6)/kg [range, 2-62.2 × 10(6)/kg] vs. 5.24 × 10(6)/kg [range, 2.4-29.8 × 10(6)/kg]). Filgrastim was used for 6 fewer days in the RAP cohort (median 5 days [range, 0-11 days] vs. 11 days [range, 9-47 days]). There was a small absolute but significant difference in median time to neutrophil recovery in the HD1 cohort for the whole group, 10 days (range, 8-46 days) vs. 11 days (range, 9-22 days) (P = .03) and in patients with myeloma; 10 days (range, 9-14 days) vs. 11 days (range, 9-18 days) (P < .0001) as compared to the RAP cohort. There was no difference in median inpatient duration, 13 days (range, 10-26 days) vs. 12 days (range, 1-38 days) (P = .22) and 3-year survival (79% vs. 83% [P = .43]) between HD1 and RAP cohorts respectively. The use of a RAP to identify patients likely to benefit from prophylactic filgrastim is safe and results in cost savings. Patients with myeloma benefit from earlier introduction of filgrastim in terms of neutrophil recovery; this disease-specific observation is an important consideration for future studies.

This study represents the first reported outcomes for patients with advanced ovarian cancer (AOC) in South-West Wales undergoing treatment with primary debulking surgery or primary chemotherapy respectively. This is a retrospective study of consecutive, unselected patients with advanced ovarian, fallopian tube or primary peritoneal cancer (FIGO III/IV) presenting to a regional cancer centre between October 2007 and October 2014. Patients were identified from Welsh Cancer Services records and relevant data was extracted from electronic National Health Service (NHS) databases. Main outcome measures were median overall survival (OS), progression free survival (PFS) and perioperative adverse events. Hazard ratio estimation was carried out with Cox Regression analysis and survival determined by Kaplan-Meier plots. Of 220 women with AOC, 32.3% underwent primary debulking surgery (PDS) and 67.7% primary chemotherapy and interval debulking (PCT-IDS). Patients were often elderly (median age 67 years) with a poor performance status (26.5% PS >1). Complete cytoreduction (0cm residual) was achieved in 32.4% of patients in the PDS group and in 50.0% of patients undergoing IDS. Median OS for all patients was 21.9 months (PDS: 27.0 and PCT-IDS: 19.2 months; p >0.05) and median PFS was 13.1 months (PDS: 14.3 months and PCT-IDS: 13.0 months; p >0.05). Median overall and progression free survival for patients achieving complete cytoreduction were 48.0 and 23.2 months respectively in the PDS group and 35.4 months and 18.6 months in the IDS group (p >0.05). This retrospective study of an unselected, consecutive cohort of women with AOC in South West Wales shows comparable survival outcomes with recently published trials, despite the relatively advanced age and poor performance status of our patient cohort. Over the seven-year study period, our data also demonstrated a non-significant trend towards improved survival following primary surgery in patients who achieved maximal cytoreduction. Our future aim therefore is to examine and develop the role of extended surgery in these patients. Copyright © 2017 Elsevier Ltd. All rights reserved.

Choline and betaine are involved in several similar health-relevant metabolic pathways, but the foods sources are different. We have assessed their intakes (individual, sums and ratios) from a dominantly Chinese food cultural point of view. A representative free-living Taiwanese population aged 13-64 years was drawn from the Nutrition and Health Survey in Taiwan (NAHSIT) 1993-1996. Food intake was derived from interviews as 24-hour recalls. The USDA database, with adaptations for Taiwan, provided choline and betaine food compositions. Major food contributors of these nutrients were identified and compared with data from the US Framingham offspring study. Mean and variance reduced median nutrient intakes were calculated. Top ten major food contributors of choline in Taiwan were eggs, pork, chicken, fish, soybean and its products, dark leafy vegetables, dairy, fruit, wheat products and light leafy vegetables in sequence. For betaine, the top ten were dark leafy vegetables, wheat products, fish, pork, bread, chicken, cake/cookies, grain-based alcoholic beverages, rice and its products and sauces. The main contributors of choline in Taiwan and the USA were, respectively, eggs and red meat; and for betaine, greens were similarly best contributor. The rankings of the main food contributors of choline and betaine differed substantially between Taiwan and the USA. The total daily intakes (mean±SE, mg) in Taiwan for choline were 372±19 (median=348) in men and 265±9 (median 261) for women; for betaine, values were 101±3 (median 93) in men and 78±8 (median 76) for women. These allow for health outcome considerations.

This retrospective report describes experience with defibrotide in children with hepatic veno-occlusive disease (HVOD) following hematopoietic progenitor cell transplant (HPCT) in a single institution. Children who had undergone HPCT between February 1999 and June 2001 and between July 2003 and September 2004 and who received defibrotide during their admission were identified. Demographic data and information regarding the clinical course of these patients were abstracted from their health records. Fourteen children (mean age: 9.3 years; range: 0.4-18.1) who underwent HPCT during the study period received defibrotide for the treatment of HVOD; nine were girls. Most patients underwent HPCT for hematologic malignancies (8/14) and received matched unrelated donor transplants (8/14). Conditioning regimens included cyclophosphamide with total body irradiation (5/14) and busulfan followed by cyclophosphamide (7/14). HVOD was diagnosed on transplant day -4 to +33 (median: +10.5); defibrotide was started on transplant day -4 to +40 (median: +12). The median initial defibrotide dose was 33 mg/kg/day (11-40 mg/kg/day); the median maximum defibrotide dose was 38.5 mg/kg/day (11-81 mg/kg/day). The median duration of defibrotide therapy was 16 days (4-37 days). Defibrotide was discontinued due to clinical improvement (9), death (3), drug unavailability (1), and neurological toxicity (1). Gastrointestinal hemorrhage was observed in two patients and intra-cranial hemorrhage was observed in one patient during defibrotide therapy. The survival rate to day +100 was 79%. Defibrotide appears to be an effective and relatively safe treatment for children with HVOD. (c) 2006 Wiley-Liss, Inc.

Eggerthella lenta is an emerging pathogen that has been underrecognized due to historical difficulties with phenotypic identification. Until now, its pathogenicity, antimicrobial susceptibility profile, and optimal treatment have been poorly characterized. In this article, we report the largest cohort of patients with E. lenta bacteremia to date and describe in detail their clinical features, microbiologic characteristics, treatment, and outcomes. We identified 33 patients; the median age was 68 years, and there was no gender predominance. Twenty-seven patients (82%) had serious intra-abdominal pathology, often requiring a medical procedure. Of those who received antibiotics (28/33, 85%), the median duration of treatment was 21.5 days. Mortality from all causes was 6% at 7 days, 12% at 30 days, and 33% at 1 year. Of 26 isolates available for further testing, all were identified as E. lenta by both commercially available matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS) systems, and none were found to harbor a vanA or vanB gene. Of 23 isolates which underwent susceptibility testing, all were susceptible to amoxicillin-clavulanate, cefoxitin, metronidazole, piperacillin-tazobactam, ertapenem, and meropenem, 91% were susceptible to clindamycin, 74% were susceptible to moxifloxacin, and 39% were susceptible to penicillin.

One of the commonly used systemic agents for the treatment of aggressive fibromatosis is the anti-oestrogen drug tamoxifen. However, data on efficacy and optimum methods of response assessment are limited, consisting mainly of small case series and reports. A retrospective database was used to identify consecutive patients diagnosed with aggressive fibromatosis (AF) and treated with tamoxifen plus/minus non-steroidal anti-inflammatory drugs at our tertiary referral centre between 2007 and 2014. MRI and symptom changes were recorded. Thirty-two patients (13 male 19 female, median age 41 years) were included. Median duration of treatment with tamoxifen was 316 days. Of 9 patients with progressive disease by RECIST 1.1 (28%): 4 patients experienced worsening symptoms; 3 patients had improved symptoms and 2 had no change in symptoms. Of 22 patients with stable disease (69%): 11 had no change in symptoms; 6 had improved symptoms and 5 patients had worsening symptoms. One patient achieved a partial response with improved symptoms. No relationship was identified between symptomatic benefit and response by RECIST 1.1 on MRI. Prospective studies in AF should incorporate endpoints focusing on patient symptoms.

We examined the feasibility of using a remotely manoeuverable robot to make home hazard assessments for fall prevention. We employed use-case simulations to compare robot assessments with in-person assessments. We screened the homes of nine elderly patients (aged 65 years or more) for fall risks using the HEROS screening assessment. We also assessed the participants' perspectives of the remotely-operated robot in a survey. The nine patients had a median Short Blessed Test score of 8 (interquartile range, IQR 2-20) and a median Life-Space Assessment score of 46 (IQR 27-75). Compared to the in-person assessment (mean = 4.2 hazards identified per participant), significantly more home hazards were perceived in the robot video assessment (mean = 7.0). Only two checklist items (adequate bedroom lighting and a clear path from bed to bathroom) had more than 60% agreement between in-person and robot video assessment. Participants were enthusiastic about the robot and did not think it violated their privacy. The study found little agreement between the in-person and robot video hazard assessments. However, it identified several research questions about how to best use remotely-operated robots.

Sleep state development in preterm neonates can provide crucial information regarding functional brain maturation and give insight into neurological well being. However, visual labeling of sleep stages from EEG requires expertise and is very time consuming, prompting the need for an automated procedure. We present a robust method for automated detection of preterm sleep from EEG, over a wide postmenstrual age ([Formula: see text] age) range, focusing first on Quiet Sleep (QS) as an initial marker for sleep assessment. Our algorithm, CLuster-based Adaptive Sleep Staging (CLASS), detects QS if it remains relatively more discontinuous than non-QS over PMA. CLASS was optimized on a training set of 34 recordings aged 27-42 weeks PMA, and performance then assessed on a distinct test set of 55 recordings of the same age range. Results were compared to visual QS labeling from two independent raters (with inter-rater agreement [Formula: see text]), using Sensitivity, Specificity, Detection Factor ([Formula: see text] of visual QS periods correctly detected by CLASS) and Misclassification Factor ([Formula: see text] of CLASS-detected QS periods that are misclassified). CLASS performance proved optimal across recordings at 31-38 weeks (median [Formula: see text], median MF 0-0.25, median Sensitivity 0.93-1.0, and median Specificity 0.80-0.91 across this age range), with minimal misclassifications at 35-36 weeks (median [Formula: see text]). To illustrate the potential of CLASS in facilitating clinical research, normal maturational trends over PMA were derived from CLASS-estimated QS periods, visual QS estimates, and nonstate specific periods (containing QS and non-QS) in the EEG recording. CLASS QS trends agreed with those from visual QS, with both showing stronger correlations than nonstate specific trends. This highlights the benefit of automated QS detection for exploring brain maturation.

Many reports suggest gender disparity in cardiac care as a contributor to the increased mortality among women with heart disease. We sought to identify gender differences in the management of Myocardial Infarction (MI) Alert-activated ST-segment elevation myocardial infarction (STEMI) patients that may have resulted from prehospital initiation. A retrospective database was created for MI Alert STEMI patients who presented to the emergency department (ED) of an academic community hospital with 74,000 annual visits from April 2000 through December 2008. Included were patients meeting criteria for an MI Alert (an institutional clinical practice guideline designed to expedite cardiac catheterization for STEMI patients). Data points (before and after initiation of a prehospital alert protocol) were compared and used as markers of therapy: time to ECG, receiving β-blockers, and time to the catheterization laboratory (cath lab). Differences in categorical variables by patient sex were assessed using the χ(2) test. Medians were estimated as the measure of central tendency. Quantile regression models were used to assess differences in median times between subgroups. A total of 1231 MI Alert charts were identified and analyzed. The majority of the study population were male (70%), arrived at the ED via ambulance (60.1%), and were taking a β-blocker (67.8%) or aspirin (91.6%) at the time of the ED admission. Female patients were more likely than male patients to arrive at the ED via ambulance (65.9% vs 57.6%, respectively; P = 0.014). The median age of female patients was 68 years, whereas male patients were significantly younger (median age, 59 years; P < 0.001). The proportion of patients currently taking a β-blocker or low-dose aspirin did not vary by gender. Overall, 78.2% of the MI Alert patients arriving at the ED were MI2 (alert initiated by ED physician), and this did not vary by gender (P = 0.33). A total of 1064 MI Alert patients went to the cath lab: 766 male patients (88.9%) and 298 female patients (80.8%). Overall, the median time to cath lab arrival was 79 minutes for men and 81 minutes for women (P = 0.38). Overall, the median time to cath lab arrival significantly decreased from MI1 to MI3, (P(trend) < 0.001). For prehospital-initiated alerts (MI3), the median time to cath lab arrival was the same for men and women (64 minutes; P = 1.0). For hospital-initiated alerts, time to cath lab arrival was 82 minutes for male patients and 84 minutes for female patients (P = 0.38). Prehospital activation of the process decreased the time to the cath lab by 19 minutes (P < 0.001; 95% CI, 13.2-24.8). No significant gender differences were apparent in the STEMI patients analyzed, whether the MI Alert was initiated in the ED or prehospital initiated. Initiating prehospital-based alerts significantly decreased the time to the cath lab. Copyright © 2012 Elsevier HS Journals, Inc. All rights reserved.

Background: Objectives were to describe the proportion of deaths due to treatment-related mortality (TRM) and to identify risk factors and probable causes of TRM among paediatric cancer deaths in a population-based cohort. Methods: We included children with cancer ⩽18 years diagnosed and treated in Ontario who died between January 2003 and December 2012. Deaths were identified using a provincial registry, the Pediatric Oncology Group of Ontario Networked Information System. Probable causes of TRM were described. Results: Among the 964 deaths identified, 821 were included. The median age at diagnosis was 6.6 years (range 0–18.8) and 51.8% had at least one relapse. Of the deaths examined, TRM occurred in 217/821 (26.4%) while 604/821 (73.6%) were due to progressive cancer. Deaths from TRM did not change over time. Using multiple regression, younger age, leukaemia diagnosis and absence of relapse were independently positively associated with TRM. The most common probable causes of TRM were respiratory, infection and haemorrhage. Conclusions: TRM was responsible for 26.4% of deaths in paediatric cancer. Underlying diagnosis, younger age and absence of relapse were associated with TRM and causes of TRM differed by diagnosis group. Future work should evaluate TRM rate and risk factors among newly diagnosed cancer patients. PMID:28095399

To assess the safety of selective use of triple assessment with omission of radiological assessment proposed in patients <40-years old. Data were collected retrospectively for all patients seen in the one-stop breast clinic between January 2014 and August 2015. Demographics, symptoms, diagnostics, and treatment details were recorded. Subgroup and logistic regression analysis was performed to identify predictors for breast cancer. Of the 3,305 patients included, 95.6% (n=3,161) were first-time referrals. 57.6% (n=1,903) had a breast lump, and 4% (n=133) had a high-risk family history; 75.6% (n=2,499) underwent imaging and 16.7% (n=552) underwent a biopsy. The median age was 29 years (interquartile range [IQR]=25-34). Breast cancer was diagnosed in 29 cases (0.88%) and 3.2% (n=105) had surgery. Median referral-to-diagnosis time was 13 days (IQR=9-14) and referral-to-surgery time was 44 days (IQR=34-95). Patients with breast cancer were significantly older (33 versus 28 years, p=0.016). All patients were first-time referrals. Most patients had a breast lump with low suspicion on clinical examination and breast cancer identified on imaging. Time-to-diagnosis (12 versus 14 days, p=0.017) and time-to-surgery (37 versus 67 days, p=0.012) was significantly shorter in the breast cancer group. Comparative older age (odds ratio [OR]=1.08, 95% confidence interval [CI]: 1.01-1.15) and breast lump (OR=11.43,95% CI: 2.72-48.07) were the only significant predictors of cancer on uni/multivariate regression. Triple assessment is also the best practice for all patients in the younger age group. This cohort should not be treated any differently regarding one-stop clinic infrastructure as the cancers detected were not clinically malignant. Missed cancers in this age group would have significant personal, clinical, and legal consequences. Copyright © 2018 The Royal College of Radiologists. Published by Elsevier Ltd.

Age at the final menstrual period is of clinical and public health interest because the age at which natural menopause occurs may be a marker of ageing and health, and in general the menopausal transition increases the risk of many diseases, e.g. redistribution in the pattern of adiposity during the menopausal transition may increase risk of metabolic disease. The purpose of this research was to study the relationship between the menopausal status and body fatness. A random sample of 1932 Hungarian women was studied. Body composition was estimated by body impedance analysis. In a subsample free estradiol and progesterone levels in saliva were quantified. Body fat mass increased until the late 50s and then had a decrease through senescence. Premenopausal women who were much older than the median age at menopause had a higher amount of fat than their postmenopausal age-peers, while postmenopausal women, whose menopause occurred much earlier than the median age at menopause, had less fat than their premenopausal age-peers. The body fat mass in premenopausal women with low levels of sex hormones was always below the age-median value of the menopausal status subgroups, while the body fat mass of postmenopausal women with high levels of sex hormone levels was above the age-median values. The analysis of body fatness in the menopausal transition revealed that (1) the rate of reproductive ageing and the body fat pattern were significantly related, and (2) body fat mass of women with unexpected levels of sex hormones was related more to their hormonal levels than to their menopausal status or their age. Thus future epidemiological screenings of women exposed to higher levels of menopause-related health risks should be expanded beyond the estimation of menopausal status based only on menstrual history to include sex hormone level assessment, as well as body composition analysis.

Lynch syndrome is an autosomal dominant syndrome of familial malignancies resulting from germ line mutations in DNA mismatch repair (MMR) genes. Our goal was to take a pathway-based approach to investigate the influence of polymorphisms in cell cycle-related genes on age of onset for Lynch syndrome using a tree model. We evaluated polymorphisms in a panel of cell cycle-related genes (AURKA, CDKN2A, TP53, E2F2, CCND1, TP73, MDM2, IGF1, and CDKN2B) in 220 MMR gene mutation carriers from 129 families. We applied a novel statistical approach, tree modeling (Classification and Regression Tree), to the analysis of data on patients with Lynch syndrome to identify individuals with a higher probability of developing colorectal cancer at an early age and explore the gene-gene interactions between polymorphisms in cell cycle genes. We found that the subgroup with CDKN2A C580T wild-type genotype, IGF1 CA-repeats >or=19, E2F2 variant genotype, AURKA wild-type genotype, and CCND1 variant genotype had the youngest age of onset, with a 45-year median onset age, while the subgroup with CDKN2A C580T wild-type genotype, IGF1 CA-repeats >or=19, E2F2 wild-type genotype, and AURKA variant genotype had the latest median age of onset, which was 70 years. Furthermore, we found evidence of a possible gene-gene interaction between E2F2 and AURKA genes related to CRC age of onset. Polymorphisms in these cell cycle-related genes work together to modify the age at the onset of CRC in patients with Lynch syndrome. These studies provide an important part of the foundation for development of a model for stratifying age of onset risk among those with Lynch syndrome.

We have investigated the steady-state plasma concentrations of midazolam during continuous subcutaneous administration in palliative care. Using a sensitive gas chromatography with electron capture detector assay, plasma concentrations of midazolam were measured in 11 patients (median age 68 years; range 47-82 years; six females) receiving the drug by continuous subcutaneous infusion (median rate 20 mg/day; range 10-60 mg/day). While not significant, the infusion rate tended to decrease with increasing age of the patient (Spearman's p = -0.51; p = 0.11). The steady-state plasma concentration range was 10-147 ng/ml, with a median of 30 ng/ml. Infusion rates and plasma concentrations of midazolam were correlated (Spearman's p = 0.71; p < 0.05). No other significant relationships were found between plasma concentrations and the variables of age, sex and liver function.

Objective To analyze the clinical characteristics and endoscopic features of patients with lanthanum deposition in the stomach. Patients We retrospectively reviewed seven patients with lanthanum deposition in the stomach who were diagnosed at Okayama Saiseikai General Hospital. We investigated the patient sex, age at diagnosis, medical and medication histories, gastrointestinal symptoms, complications, presence or absence of gastric atrophy, and outcome. We also investigated any changes in the endoscopic features if previous endoscopic images were available. Results Seven patients (six males and one female) had lanthanum deposition. The median age was 65 years (range, 50-79 years). All patients had been undergoing dialysis (continuous ambulatory peritoneal dialysis in one patient, hemodialysis in six patients). The dialysis period ranged from 16 to 73 months (median, 52 months). The patients had all been taking lanthanum carbonate for a period ranging from 5 to 45 months (median, 27 months). Gastric atrophy was noted in 6 patients (85.7%). One patient had difficulty swallowing, and 1 other patient had appetite loss. The other 5 patients were asymptomatic. Endoscopic features included annular whitish mucosa (n = 4), diffuse whitish mucosa (n = 3), and whitish spots (n = 2). Five patients underwent multiple esophagogastroduodenoscopy. The endoscopic features were unchanged in 2 patients, whereas the whitish mucosa became apparent and spread during the course in 3 patients. Conclusion We identified 7 patients with lanthanum deposition in the stomach. All patients showed whitish lesions macroscopically. Although the pathogenicity of gastric lanthanum deposition is uncertain, lanthanum-related lesions in the stomach progressed during continuous lanthanum phosphate intake in several patients.

Laparoscopic colectomy for both benign and malignant disease, including inflammatory bowel disease (IBD), has recently been shown to have many advantages compared with open surgery. This study aimed to compare the effect of laparoscopic versus open subtotal colectomy (STC) for IBD on overall morbidity. A total of 99 patients undergoing STC for IBD at our institution from 2007 through 2011 were identified. Patients undergoing open STC were compared with patients undergoing laparoscopic STC. Outcomes included 30-day morbidity, conversion to laparotomy, intraoperative blood loss, operative time, admission time, late onset complications and 30-day mortality. Results are presented as median values. A total of 57 patients underwent open STC (Group 1) and 42 patients laparoscopic STC (Group 2). Group 1 comprised 26 males and 31 females, with a median age of 35 years and a body mass index (BMI) of 23.2 kg/m2. Group 2 comprised 18 males and 24 females, with a median age of 34 years and a BMI of 23.5 kg/m2. Group 2 had less morbidity (42.9% versus 75.4%, p < 0.002), reduced blood loss (100 ml versus 200 ml, p < 0.001), longer operative time (193.5 min. versus 128 min., p < 0.001), shorter length of hospital stay (six days versus 16 days, p < 0.001) than Group 1. One patient died (Group 1). There was no difference in late onset complications and no conversions to laparotomy in the laparoscopic group. Laparoscopic STC has a longer operative time, but improves short-term outcomes compared with open surgery. not relevant. not relevant.

To determine the prevalence and nature of residual cognitive disability after inpatient rehabilitation for children aged 7-18 years with traumatic injuries. This retrospective cohort study included children aged 7-18 years in the Uniform Data System for Medical Rehabilitation who underwent inpatient rehabilitation for traumatic injuries in 523 facilities from 2002-2011. Traumatic injuries were identified by standardized Medicare Inpatient Rehabilitation Facility-Patient Assessment Instrument codes. Cognitive outcomes were measured by the Functional Independence Measure instrument. A validated, categorical staging system derived from responses to the items in the cognitive domain of the functional independence measure was used and consisted of clinically relevant levels of cognitive achievement from stage 1 (total cognitive disability) to stage 7 (completely independent cognitive function). There were 13,798 injured children who completed inpatient rehabilitation during the 10-year period. On admission to inpatient rehabilitation, patients with traumatic brain injury (TBI) had more cognitive disability (median stage 2) than those with spinal cord injury or other injuries (median stage 5). Cognitive functioning improved for all patients, but children with TBI still tended to have significant residual cognitive disability (median stage on discharge, 4). Injured children gained cognitive functionality throughout inpatient rehabilitation. Those with TBI had more severe cognitive disability on admission and more residual disability on discharge. This is important not only for patient and family expectation setting but also for resource and service planning, as discharge from inpatient rehabilitation is a critical milestone for reintegration into society for children with serious injury.

Emergency Department (ED) encounters for ethanol intoxication are becoming increasingly common. The purpose of this study was to explore factors associated with ED length of stay (LOS) for ethanol intoxication encounters. This was a multi-center, retrospective, observational study of patients presenting to the ED for ethanol intoxication. Data were abstracted from the electronic medical record. To explore factors associated with ED LOS, we created a mixed-effects generalized linear model. We identified 18,664 eligible patients from 6 different EDs during the study period (2012-2016). The median age was 37years, 69% were male, and the median ethanol concentration was 213mg/dL. Median LOS was 348min (range 43-1658). Using a mixed-effects generalized linear model, independent variables associated with a significant increase in ED LOS included use of parenteral sedation (beta=0.30, increase in LOS=34%), laboratory testing (beta=0.21, increase in LOS=23%), as well as the hour of arrival to the ED, such that patients arriving to the ED during evening hours (between 18:00 and midnight) had up to an 86% increase in LOS. Variables not significantly associated with an increase in LOS included age, gender, ethanol concentration, psychiatric disposition, using the ED frequently for ethanol intoxication, CT use, and daily ED volume. Variables such as diagnostic testing, treatments, and hour of arrival may influence ED LOS in patients with acute ethanol intoxication. Identification and further exploration of these factors may assist in developing hospital and community based improvements to modify LOS in this population. Copyright © 2017 Elsevier Inc.

Systemic lupus erythematosus (SLE) frequently has neuropsychiatric involvement including affective disorders, psychosis, and cognitive dysfunction. Evidence suggests that anorexia nervosa (AN) in adolescents with SLE may be triggered by steroid-induced changes in weight and body shape. We propose that AN may be another manifestation of neuropsychiatric SLE and should be considered in this patient population. A retrospective chart review identified 7 children/adolescents diagnosed with SLE and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnostic criteria for AN, restrictive subtype, at the Hospital for Sick Children in Toronto between January 1989 and January 2011. One patient developed AN 15 months after being diagnosed with SLE that was attributed to prednisone-induced weight gain and cushingoid appearance. Of the remaining 6 patients, the median age at onset of AN symptoms was 12.2 years and diagnosis of AN was 13.6 years. The median age at SLE diagnosis was 14.2 years with median time after onset of AN symptoms of 20 months (7.5-32 months). All patients had evidence of joint symptoms and a positive antinuclear antibody, and 50% had lymphopenia at the time of SLE diagnosis. Treatment of SLE resulted in improvement of AN in all patients. The timing of the clinical presentation of AN in relation to the diagnosis of SLE and response to SLE treatment suggests that AN may be a novel presentation of neuropsychiatric SLE. Patients with AN who present with or develop joint symptoms, a positive antinuclear antibody, or lymphopenia should be investigated and followed for possible SLE.

A higher capacity to grow under hypoxic conditions can lead to a more aggressive behavior of tumor cells. Determining tumor activity under hypoxia may identify chronic lymphocytic leukemia (CLL) with aggressive clinical course and predict response to chemo-immunotherapy (CIT). A metabolic score was generated by determining pyruvate kinase and lactate dehydrogenase, key enzymes of glycolysis, ex vivo in primary CLL samples under normoxic and hypoxic conditions. This score was further correlated with clinical endpoints and response to CIT in 96 CLL patients. 45 patients were classified as metabolic high risk (HR), 51 as low risk (LR). Treatment-free survival (TFS) was significantly shorter in HR patients (median 394 vs 723 days, p = .021). 15 HR patients and 14 LR patients received CIT after sample acquisition. HR patients had a significantly shorter progression-free survival after treatment compared to LR patients (median 216 days vs not reached, p = .008). Multivariate analysis evaluating age, IGHV, TP53 deletion or mutation and 11q22-23 deletion besides the capacity of tumor cells to grow under severe hypoxic conditions identified the metabolic profile as the strongest independent risk factor for shorter TFS (hazard ratio 2.37, p = .011). The metabolic risk can provide prognostic and predictive information complementary to genetic biomarkers and identify patients who might benefit from alternative treatment approaches.

Prognostic factors for survival after liver resection for metastatic colorectal cancer identified up to date are quite inconsistent with a great inter-study variability. In this study we aimed to identify predictors of outcome in our patient population. A series of 70 consecutive patients from the oncological hepatobiliary database, who had undergone curative hepatic surgical resection for hepatic metastases of colorectal origin, operated between 2006 and 2011, were identified. At 44.6 months (range 13.7-73), 30 of 70 patients (42.85%) were alive. Patient demographics, primary tumor and liver tumor factors, operative factors, pathologic findings, recurrence patterns, disease-free survival (DFS), overall survival (OS) and cancer-specific survival (CSS) were analyzed. Clinicopathologic variables were tested using univariate and multivariate analyses. The 3-year CSS after first hepatic resection was 54%. Median CSS survival after first hepatic resection was 40.2 months. Median CSS after second hepatic resection was 24.2 months. The 3-year DFS after first hepatic resection was 14%. Median disease free survival after first hepatic resection was 18 months. The 3-year DFS after second hepatic resection was 27% and median DFS after second hepatic resection 12 months. The 30-day mortality and morbidity rate after first hepatic resection was 5.71% and 12.78%, respectively. In univariate analysis CSS was significantly reduced for the following factors: age >53 years, advanced T stage of primary tumor, moderately- poorly differentiated tumor, positive and narrow resection margin, preoperative CEA level >30 ng/ml, DFS <18 months. Perioperative chemotherapy related to metastasectomy showed a trend in improving CSS (p=0.07). Perioperative chemotherapy improved DFS in a statistically significant way (p=0.03). Perioperative chemotherapy and achievement of resection margins beyond 1 mm were the major determinants of both CSS and DFS after first liver resection in multivariate analysis. In our series predictors of outcome in multivariate analysis were resection margins beyond 1mm and perioperative chemotherapy. Studies on larger population and analyses of additional clinicopathologic factors like genetic markers could contribute to development of clinical scoring models to assess the risk of relapse and survival.

To determine the prevalence of self-reported 1-year injury history and examine its association with preparticipation evaluation components aimed at predicting future injury risk (PPE-IP) among preprofessional ballet and contemporary dancers. Cross-sectional study. Preprofessional ballet school, university contemporary dance program. Full-time preprofessional ballet and contemporary dancers. Preparticipation evaluation consisted of the Athletic Coping Skills Inventory-28, body mass index, total bone mineral density, ankle range of motion, active standing turnout, lumbopelvic control, unipedal dynamic balance, and Y-Balance test. Self-reported 1-year history of dance-related medical attention and/or time-loss injury. A total of 155 ballet [n = 90, 80 females, median age 15 years (range 11-19)] and contemporary [n = 65, 63 females, median age 20 years (range 17-30)] dancers participated. Forty-six percent (95% confidence interval (CI), 38.4-54.6) reported a 1-year injury history. Self-reported injury history was not associated with any PPE-IP, however, an influence of age and psychological coping skills on the relationship between 1-year injury history and PPE-IP was identified. Multivariable analyses revealed that prevalence of 1-year injury history did not differ by age [referent group <15 years; 15-18 years: odds ratio (OR) 0.80 (95% CI, 0.35-1.79); >18 years: OR 0.69 (95% CI, 0.30-1.56)], or level of psychological coping skills [OR 1.35 (95% CI, 0.61-2.94)]. The prevalence of self-reported 1-year injury history among preprofessional ballet and contemporary dancers is high. Although measures of PPE-IP did not differ based on injury history, it is important that age and psychological coping skills are considered in future dance injury prevention and prediction research.

We used the SEER (Surveillance Epidemiology and End Results) database (1999-2010) to analyze the clinical practice patterns and overall survival in patients with gliomatosis cerebri (GC), or glioma involving 3 or more lobes of the cerebrum. We identified 111 patients (age ≥18 years) with clinically or microscopically diagnosed GC in the SEER database. Analyses were performed to determine clinical practice patterns for these patients and whether these practices were associated with survival. Fifty-eight percent of the 111 patients with GC received microscopic confirmation of their diagnosis. Of the remaining patients, 40% were diagnosed via imaging or laboratory tests, and 2% had unknown methods of diagnosis. Seven percent of patients who did not have microscopic confirmation of their diagnosis received radiation therapy. Radiation therapy and surgery were not associated with survival. The only variable significantly associated with overall survival was age at diagnosis. Patients aged 18-50 years showed improved survival relative to patients aged >50 years (median survival, 11 and 6 months, respectively; P = 0.03). For patients aged >50 years, improved overall survival was observed in the post-temozolomide era (2005-2010) relative to those treated in the pre-temozolomide era (1999-2004) (median survival, 9 and 4 months, respectively; P = 0.005). In the SEER database, ∼40% of the patients with glioma with imaging findings of GC do not receive microscopic confirmation of their diagnosis. We propose that tissue confirmation is warranted in patients with GC, because genomic analysis of these specimens may provide insights that will contribute to meaningful therapeutic intervention.

There is limited data regarding outcomes of Ewing's sarcoma family of tumors in adolescents and adults compared with the same tumors in childhood. The aim of the study was to analyze prognostic factors and treatment results in a cohort of adolescents and adults with non-metastatic skeletal Ewing's sarcoma family of tumors. From 1992-2008, 90 adolescents and adults with Ewing's sarcoma family of tumors of the bone were referred to our institution. Sixty-five (72%) non-metastatic patients with analyzable data and treated in our institution were retrospectively evaluated. All patients were treated with alternated chemotherapy regimens administered every 3 weeks. The local treatment modality was selected according to tumor and patient characteristics. The median age was 21 years (range, 13-50). Most patients (74%) were >17 years of age. Forty-six percent of the tumors were located in the extremities. Local therapy was surgery in 45 patients and radiotherapy alone in 19 patients. Twenty-one patients received preoperative and 13 patients postoperative radiotherapy. Median follow-up was 43 months (range, 7-167). The 5-year event-free and overall survival rates for all patients were 44% and 49%, respectively. On univariate survival analysis, event-free and overall survival were worse for patients >17 years of age, tumor size >8 cm in diameter, an axial location, positive surgical margins, and poor histopathological response (<90% necrosis). Age, tumor site and tumor size on event-free and overall survival remained significant on multivariate analysis. We identified age, tumor size, and tumor site as independent prognostic factors, in accord with the Western literature. These patients require novel treatment modalities.

Mexican Americans are one of the largest and fastest growing ethnic groups in the United States, yet we have limited knowledge regarding changes (i.e., developmental trajectories) in cultural orientation based upon their exposure to the Mexican American and mainstream cultures. We examined the parallel trajectories of Mexican American and mainstream cultural values in a sample of 749 Mexican American adolescents (49% female) across assessments during the fifth grade (approximately 11 years of age), the seventh grade (approximately 13 years of age) and the tenth grade (approximately 16 years of age). We expected that these values would change over this developmental period and this longitudinal approach is more appropriate than the often used median split classification to identify distinct types of acculturation. We found four distinct acculturation trajectory groups: two trajectory groups that were increasing slightly with age in the endorsement of mainstream cultural values, one of which was relatively stable in Mexican American cultural values while the other was declining in their endorsement of these values; and two trajectory groups that were declining substantially with age in their endorsement of mainstream cultural values, one of which was also declining in Mexican American cultural values and the other which was stable in these values. These four trajectory groups differed in expected ways on a number of theoretically related cultural variables, but were not highly consistent with the median split classifications. The findings highlight the need to utilize longitudinal data to examine the developmental changes of Mexican American individual’s adaptation to the ethnic and mainstream culture in order to understand more fully the processes of acculturation and enculturation.

Pancreaticoduodenectomy (PD) is associated with high morbidity, which is perceived to be increased in the elderly. To our knowledge there have been no Australian series that have compared outcomes of patients over the age of 80 undergoing PD to those who are younger. Patients who underwent PD between January 2008 and November 2015 were identified from a prospectively maintained database. A total of 165 patients underwent PD of whom 17 (10.3%) were aged 80 or over. The pre-operative health status, according to American Society of Anesthesiologists class was similar between the groups (P = 0.420). The 90-day mortality rates (5.9% in the elderly and 2% in the younger group; P = 0.355) and the post-operative complication rates (64.7% in the elderly versus 62.8% in the younger group; P = 0.88) were similar. Overall median length of hospital stay was also similar between the groups, but older patients were far more likely to be discharged to a rehabilitation facility than younger patients (47.1 versus 12.8%; P < 0.0001). Older patients with pancreatic adenocarcinoma (n = 10) had significantly lower median survival than the younger group (n = 69) (16.6 versus 22.5 months; P = 0.048). No significant differences were seen in the rate of complications following PD in patients aged 80 or over compared to younger patients, although there appears to be a shorter survival in the elderly patients treated for pancreatic cancer. Careful selection of elderly patients and optimal peri-operative care, rather than age should be used to determine whether surgical intervention is indicated in this patient group. © 2017 Royal Australasian College of Surgeons.

To assess the clinical characteristics, diagnosis, and outcome of cardiac sarcoidosis in a single institution sarcoidosis clinic. Patients with cardiac sarcoidosis were identified using refined World Association of Sarcoidosis and Other Granulomatous Diseases (WASOG) criteria of highly probable and probable. Patient demographics, local and systemic treatments, and clinical outcome were collected. Of the 1,815 patients evaluated over a 6-year period, 73 patients met the WASOG criteria for cardiac sarcoidosis. The median age at diagnosis was 46 years, with a median follow-up of 8.8 years. Reduced left ventricular ejection fraction (LVEF) was the most common manifestation (54.8%). Patients with arrhythmias experienced ventricular tachycardia or severe heart block, (35.6% and 19.2%, respectively) with or without reduced LVEF. A total of 45 (61.6%) patients underwent cardiac PET scan and/or MRI, with 41 (91.1%) having a positive study. During follow-up, 10 patients (13.7%) either underwent transplant (n = 3) or died (n = 7) from sarcoidosis. Kaplan-Meier survival curves revealed 5- and 10-year survival rates of 95.5% and 93.4%, respectively. Univariate factors of age at diagnosis < 46 years, implantation of pacemaker or defibrillator, mycophenolate treatment, or LVEF > 40% were associated with improved survival. Cox regression analysis demonstrated that age ≥ 46 years and lack of an implanted pacemaker or defibrillator were the only independent predictors of mortality. The new WASOG criteria were able to characterize cardiac involvement in our sarcoidosis clinic. Age and lack of pacemaker or defibrillator were the significant predictors of mortality for cardiac sarcoidosis, and reduced LVEF < 40% was associated with worse prognosis.

2016-01-01

Background: Food-composition tables typically give measured nutrient concentrations in foods as a single summary value, often the mean, without providing information as to the shape of the distribution. Objective: Our objective was to explore how the statistical approach chosen to describe the iodine concentrations of foods affects the proportion of the population identified as having either insufficient or excessive iodine intakes. Design: We used food intake data reported by the 2009−2010 NHANES and measured iodine concentrations of Total Diet Study (TDS) foods from 4 US regions sampled in 2004–2011. We created 4 data sets, each by using a different summary statistic (median, mean, and 10th and 90th percentiles), to represent the iodine concentration distribution of each TDS food. We estimated the iodine concentration distribution of each food consumed by NHANES participants as the 4 iodine concentration summary statistics of a similar TDS food and used these, along with NHANES food intake data, to develop 4 estimates of each participant’s iodine intake on each survey day. Using the 4 estimates in turn, we calculated 4 usual iodine intakes for each sex- and age-specific subgroup. We then compared these to guideline values and developed 4 estimates of the proportions of each subgroup with deficient and excessive usual iodine intakes. Results: In general, the distribution of iodine intakes was poorly characterized when food iodine concentrations were expressed as mean values. In addition, mean values predicted lower prevalences of iodine deficiency than did median values. For example, in women aged 19–50 y, the estimated prevalence of iodine deficiency was 25% when based on median food iodine concentrations but only 5.8% when based on mean values. Conclusion: For nutrients such as iodine with highly variable concentrations in important food sources, we recommend that food-composition tables provide useful variability information, including the mean, SD, and median.

The objective of the study was to estimate the prevalence of periodontitis at state and local levels across the United States by using a novel, small area estimation (SAE) method. Extended multilevel regression and poststratification analyses were used to estimate the prevalence of periodontitis among adults aged 30 to 79 y at state, county, congressional district, and census tract levels by using periodontal data from the National Health and Nutrition Examination Survey (NHANES) 2009-2012, population counts from the 2010 US census, and smoking status estimates from the Behavioral Risk Factor Surveillance System in 2012. The SAE method used age, race, gender, smoking, and poverty variables to estimate the prevalence of periodontitis as defined by the Centers for Disease Control and Prevention/American Academy of Periodontology case definitions at the census block levels and aggregated to larger administrative and geographic areas of interest. Model-based SAEs were validated against national estimates directly from NHANES 2009-2012. Estimated prevalence of periodontitis ranged from 37.7% in Utah to 52.8% in New Mexico among the states (mean, 45.1%; median, 44.9%) and from 33.7% to 68% among counties (mean, 46.6%; median, 45.9%). Severe periodontitis ranged from 7.27% in New Hampshire to 10.26% in Louisiana among the states (mean, 8.9%; median, 8.8%) and from 5.2% to 17.9% among counties (mean, 9.2%; median, 8.8%). Overall, the predicted prevalence of periodontitis was highest for southeastern and southwestern states and for geographic areas in the Southeast along the Mississippi Delta, as well as along the US and Mexico border. Aggregated model-based SAEs were consistent with national prevalence estimates from NHANES 2009-2012. This study is the first-ever estimation of periodontitis prevalence at state and local levels in the United States, and this modeling approach complements public health surveillance efforts to identify areas with a high burden of periodontitis. © International & American Associations for Dental Research 2016.

There is a high risk of drug-related problems in nursing homes due to polypharmacy, multi-morbidity and age-related changes. We describe the drug use and compare the pharmacotherapy in two nursing homes with different staffing of physicians. We included 48 long-term patients from two nursing homes in Oslo; i.e. nursing home A (24 patients) and nursing home B (24 patients). A pharmacist recorded information on patients' drug use, identified and classified drug-related problems, and classified the drugs used according to their anticholinergic burden. Two physicians (with experience in geriatrics and nursing home medicine) assessed the clinical importance of the drug-related problems independently from each other. The physicians were blinded with respect to which nursing home the patients came from. Patients in nursing home A used a median (interquartile range [IQR]) of 7.0 (5.3-11.0) drugs, and those in nursing home B used 9.5 (8.0-12.8); the median difference was 2.0, 95% CI 1.0-4.0, p = 0.006). Patients also had lower anticholinergic drug scores in nursing home A (1.0 [0.0-2.0]) than in nursing home B (2.0 [2.0-3.8]); median difference 1.0, 95% CI 0.0-2.0, p = 0.009). Patients in home A also had lower numbers of drug-related problems (3.0 [2.0-4.0]) than those in home B (5.5 [3.3-8.0]); median difference 1.0, 85% CI 0.0-3.0, p = 0.007. No significant differences were found between the nursing homes with regard to patients' age, co-morbidity, kidney function, or dementia state, but nursing home A had a better staffing of physicians. The number of drugs used as well as the quality indicators varied considerably between the nursing homes assessed. Differences in physician staffing might be one reasonable explanation. Our study highlights the importance of systematic multidisciplinary medication reviews for quality improvement in nursing homes.

Four gamma-gultamyltransferases (GGT) fractions (b-, m-, s-, and f-GGT) have been identified in human plasma and their concentrations and ratios vary in different pathological conditions. To assess the behaviour of fractional GGT in cirrhotic patients evaluated for liver transplantation. This was a single-centre, cross-sectional study; GGT fractions were determined by gel-filtration chromatography. 264 cirrhotic patients (215 males; median age 54.5 years) were included and compared against a group of 200 healthy individuals (100 males; median age 41.5). Median (25th-75th percentile) total and fractional GGT were higher in cirrhotics, with s-GGT showing the greatest increase [36.6 U/L (21.0-81.4) vs. 5.6 U/L (3.2-10.2), P<0.0001], while the median b-GGT/s-GGT ratio was lower in cirrhotics than in healthy controls [0.06 (0.04-0.10)] vs. 0.28 (0.20-0.40), P<0.0001]. The ratio showed higher diagnostic accuracy (ROC-AUC, 95% CI: 0.951, 0.927-0.969) then either s-GGT (0.924, 0.897-0.947; P<0.05) or total GGT (0.900, 0.869-0.925; P<0.001). The diagnostic accuracy of the ratio was maintained (0.940, 0.907-0.963) in cirrhotic patients (n=113) with total GGT values within the reference range. The s-GGT fraction consisted of two components, with one (s2-GGT) showing a significant positive correlation with serum aspartate aminotransferases, alanine aminotransferase, lactate dehydrogenases (LDH), alkaline phosphatases and bilirubin, and negative with albumin. The b-GGT fraction showed a positive correlation with albumin, fibrinogen, and platelet counts, and negative with international normalized ratio, bilirubin and LDH. The ratio performs as a sensitive biomarker of the liver parenchymal rearrangement, irrespective of aetiology of cirrhosis and presence of hepatocellular carcinoma, even in patients with total GGT values within the reference range. © 2014 John Wiley & Sons A/S.

Craniopharyngiomas are frequent hypothalamo-pituitary tumors in children, presenting predominantly as cystic lesions. Morbidity from conventional treatment has focused attention on intracystic drug delivery, hypothesized to cause fewer clinical consequences. However, the efficacy of intracystic therapy remains unclear. We report the retrospective experiences of several global centers using intracystic interferon-alpha. European Société Internationale d'Oncologie Pédiatrique and International Society for Pediatric Neurosurgery centers were contacted to submit a datasheet capturing pediatric patients with cystic craniopharyngiomas who had received intracystic interferon-alpha. Patient demographics, administration schedules, adverse events, and outcomes were obtained. Progression was clinical or radiological (cyst reaccumulation, novel cysts, or solid growth). Fifty-six children (median age, 6.3 y) from 21 international centers were identified. Median follow-up from diagnosis was 5.1 years (0.3-17.7 y). Lesions were cystic (n = 22; 39%) or cystic/solid (n = 34; 61%). Previous progression was treated in 43 (77%) patients before interferon use. In such cases, further progression was delayed by intracystic interferon compared with the preceding therapy for cystic lesions (P = 0.0005). Few significant attributable side effects were reported. Progression post interferon occurred in 42 patients (median 14 mo; 0-8 y), while the estimated median time to definitive therapy post interferon was 5.8 (1.8-9.7) years. Intracystic interferon-alpha can delay disease progression and potentially offer a protracted time to definitive surgery or radiotherapy in pediatric cystic craniopharyngioma, yet demonstrates a favorable toxicity profile compared with other therapeutic modalities-important factors for this developing age group. A prospective, randomized international clinical trial assessment is warranted. © The Author(s) 2017. Published by Oxford University Press on behalf of the Society for Neuro-Oncology.

Food-composition tables typically give measured nutrient concentrations in foods as a single summary value, often the mean, without providing information as to the shape of the distribution. Our objective was to explore how the statistical approach chosen to describe the iodine concentrations of foods affects the proportion of the population identified as having either insufficient or excessive iodine intakes. We used food intake data reported by the 2009-2010 NHANES and measured iodine concentrations of Total Diet Study (TDS) foods from 4 US regions sampled in 2004-2011. We created 4 data sets, each by using a different summary statistic (median, mean, and 10th and 90th percentiles), to represent the iodine concentration distribution of each TDS food. We estimated the iodine concentration distribution of each food consumed by NHANES participants as the 4 iodine concentration summary statistics of a similar TDS food and used these, along with NHANES food intake data, to develop 4 estimates of each participant's iodine intake on each survey day. Using the 4 estimates in turn, we calculated 4 usual iodine intakes for each sex- and age-specific subgroup. We then compared these to guideline values and developed 4 estimates of the proportions of each subgroup with deficient and excessive usual iodine intakes. In general, the distribution of iodine intakes was poorly characterized when food iodine concentrations were expressed as mean values. In addition, mean values predicted lower prevalences of iodine deficiency than did median values. For example, in women aged 19-50 y, the estimated prevalence of iodine deficiency was 25% when based on median food iodine concentrations but only 5.8% when based on mean values. For nutrients such as iodine with highly variable concentrations in important food sources, we recommend that food-composition tables provide useful variability information, including the mean, SD, and median. © 2016 American Society for Nutrition.

Purpose: To identify clinical factors associated with prostate cancer-specific mortality (PCSM), adjusting for comorbidity, in elderly men with intermediate-risk prostate cancer treated with brachytherapy alone or in conjunction with external beam radiation therapy. Methods and Materials: The study cohort comprised 1,978 men of median age 71 (interquartile range, 66-75) years with intermediate-risk disease (Gleason score 7, prostate-specific antigen (PSA) 20 ng/mL or less, tumor category T2c or less). Fine and Gray's multivariable competing risks regression was used to assess whether prevalent cardiovascular disease (CVD), age, treatment, year of brachytherapy, PSA level, or tumor category was associated with the risk ofmore » PCSM. Results: After a median follow-up of 3.2 (interquartile range, 1.7-5.4) years, the presence of CVD was significantly associated with a decreased risk of PCSM (adjusted hazard ratio, 0.20; 95% CI 0.04-0.99; p = 0.05), whereas an increasing PSA level was significantly associated with an increased risk of PCSM (adjusted hazard ratio 1.14; 95% CI 1.02-1.27; p = 0.02). In the absence of CVD, cumulative incidence estimates of PCSM were higher (p = 0.03) in men with PSA levels above as compared with the median PSA level (7.3 ng/mL) or less; however, in the setting of CVD there was no difference (p = 0.27) in these estimates stratified by the median PSA level (6.9 ng/mL). Conclusions: In elderly men with intermediate-risk prostate cancer, CVD status is a negative predictor of PCSM and affects the prognostic capacity of pretreatment PSA level. These observations support the potential utility of prerandomization stratification by comorbidity to more accurately assess prognostic factors and treatment effects within this population.« less

To assess vitamin D status in Indigenous mothers and infants in the Northern Territory, and to determine whether cord blood vitamin D levels are correlated with the risk of infant hospitalisation for acute lower respiratory infection (ALRI). Within a nested cohort of 109 Indigenous mother-infant pairs recruited between 2006 and 2011, we used liquid chromatography-mass spectrometry to measure vitamin D (25(OH)D3) levels in maternal blood during pregnancy (n = 33; median gestation, 32 weeks [range, 28-36 weeks]) and at birth (n = 106; median gestation, 39 weeks [range, 34-41 weeks]), in cord blood (n = 84; median gestation, 39 weeks [range, 36-41 weeks]), and in infant blood at age 7 months (n = 37; median age, 7.1 months [range, 6.6-8.1 months]). ALRI hospitalisations during the first 12 months of infancy, identified using International Classification of Diseases coding (J09-J22, A37-A37.9). Compared with mean 25(OH)D3 levels in maternal blood during pregnancy (104 nmol/L), mean levels were 23% lower in maternal blood at birth (80 nmol/L) and 48% lower in cord blood samples (54 nmol/L). The mean cord blood 25(OH)D3 concentration in seven infants subsequently hospitalised for an ALRI was 37 nmol/L (95% CI, 25-48 nmol/L), lower than the 56 nmol/L (95% CI, 51-61 nmol/L) in the 77 infants who were not hospitalised with an ALRI (P = 0.025). Cord blood 25(OH)D3 concentrations were about half those in maternal blood during the third trimester of pregnancy (about 7 weeks earlier). Most cord blood levels (80%) were classified as vitamin D insufficient (< 75 nmol/L) by existing guidelines, and were lower among infants who were subsequently hospitalised with an ALRI.

Conflicting data exists regarding the influence of population density on colorectal cancer (CRC) outcomes; to better understand this, the present study evaluated outcomes along an urban-rural continuum. Colorectal patients aged ≥40 years from 1992 to 2002 were identified in the SEER (Surveillance, Epidemiology, and End Results) Registries of the National Cancer Institute in the USA. A total of 176 011 patients were identified, with median age 71; most lived in populous counties and were white (90%). Patients from large metropolitan counties were more often African-American, and those in rural counties were more likely to be white and have low socioeconomic status (SES). Patients from large metropolitan (>1 million) and rural counties were more likely to have metastatic disease and decreased survival compared to smaller metropolitan counties (<1 million). Late stage of presentation and diminished survival were also associated with African-American race, male sex and lower SES. Metropolitan counties with populations <1 million had superior CRC outcomes, in part secondary to race and SES.

To examine the patterns of care, outcomes, and prognostic factors for patients with head-and-neck cancer (HNC) treated with palliative radiotherapy (RT). An institutional HNC anthology and electronic patient records were used to identify patients with previously untreated HNC of mucosal or salivary gland origin who underwent palliative RT at our institution between July 2003 and June 2008. Overall survival was determined from the start date of RT to either the date of death or the date of last follow-up for living patients. The data were censored if the subject was either lost to follow-up or had not been seen for follow-up at our institution for ≥4 months. We identified 148 eligible patients. The median age was 72 years (range, 19-94). Of the 148 patients, 12 had Stage II-III, 39 Stage IVA, 36 Stage IVB, and 54 Stage IVC; for 7 patients, the stage was unknown. Oropharyngeal primary cancer (40) was the most common primary site. The Eastern Cooperative Oncology Group performance status was 0 in 15, 1 in 69, 2 in 40, 3 in 19, and 4 in 5 patients. The Adult Co-morbidity Evaluation-27 scale was 0 in 33, 1 in 47, 2 in 44, and 3 in 21. The median radiation dose was 50 Gy (range, 2-70), the median fraction number was 20 (range, 1-40), and the median total treatment time (including breaks) was 29 days (range, 1-80). At analysis, 108 patients (73%) had died, 20 (13.5%) were alive, and 20 (13.5%) had been censored. The median follow-up was 4.8 months, and the median survival time was 5.2 months. Information on the treatment response was available for 103 patients (70%). On multivariate analysis, the radiation dose was an independent predictor of both overall survival (hazard ratio 0.97, 95% confidence interval 0.96-0.99, p <.01) and treatment response (odds ratio 1.05, 95% confidence interval 1.01-1.08, p <.01). For patients considered unsuitable for curative RT, the radiation dose might be an independent predictive factor for both overall survival and treatment response. Additional research is required to more effectively select those patients who might benefit from more aggressive treatment. Copyright © 2011 Elsevier Inc. All rights reserved.

To determine the trend in the association between socioeconomic status and sex and median age at death from cystic fibrosis in England and Wales, over the past 50 years. Series of annual cross sectional studies of all registered deaths with a diagnosis of cystic fibrosis in England and Wales, from 1959 to 2008. We obtained national mortality data for cystic fibrosis from the Office for National Statistics. From 1959 to 2000, the Registrar General's Social Class coded socioeconomic status as manual or non-manual. From 2001 onwards, the National Statistics Socioeconomic Classification was implemented and socioeconomic status was split into three groups: professional and managerial, intermediate, and routine and manual. We calculated median age at death for every study year. We calculated the effects of sex and socioeconomic status on the odds of death above the median age at death for every study decade using logistic regression. From 1959 to 2008, 6750 deaths were attributed to cystic fibrosis in England and Wales. Males were more likely to die above the annual median age at death than females (from 1959 to 1999, adjusted odds ratio for socioeconomic status 1.28, 95% confidence intervals 1.13 to 1.45; from 2000 to 2008, 1.57, 1.18 to 2.08). Individuals in the highest socioeconomic class were also more likely to die above the median age of death than those in the lowest socioeconomic class (from 1959 to 2000, adjusted odds ratio for sex 2.50, 2.16 to 2.90; from 2001 to 2008, 1.89, 1.20 to 2.97). Socioeconomic status and sex remain strong determinants of survival from cystic fibrosis in England and Wales, and the magnitude of these effects does not appear to have substantially reduced over time.

We investigated whether race was associated with risk of death following brachytherapy-based treatment for localized prostate cancer, adjusting for age, cardiovascular comorbidity, treatment, and established prostate cancer prognostic factors. The study cohort was composed of 5,360 men with clinical stage T1-3N0M0 prostate cancer who underwent brachytherapy-based treatment at 20 centers within the 21st Century Oncology consortium. Cox regression multivariable analysis was used to evaluate the risk of death in African-American and Hispanic men compared to that in Caucasian men, adjusting for age, pretreatment prostate-specific antigen (PSA) level, Gleason score, clinical T stage, year and type of treatment, median income, and cardiovascular comorbidities. After a median follow-up of 3 years, there were 673 deaths. African-American and Hispanic races were significantly associated with an increased risk of all-cause mortality (ACM) (adjusted hazard ratio, 1.77 and 1.79; 95% confidence intervals, 1.3-2.5 and 1.2-2.7; p < 0.001 and p = 0.005, respectively). Other factors significantly associated with an increased risk of death included age (p < 0.001), Gleason score of 8 to 10 (p = 0.04), year of brachytherapy (p < 0.001), and history of myocardial infarction treated with stent or coronary artery bypass graft (p < 0.001). After adjustment for prostate cancer prognostic factors, age, income level, and revascularized cardiovascular comorbidities, African-American and Hispanic races were associated with higher ACM in men with prostate cancer. Additional causative factors need to be identified. Copyright © 2011 Elsevier Inc. All rights reserved.

Obesity may impair sexual function through multiple mechanisms, but little is known about sexual dysfunction among adults with severe obesity seeking bariatric procedures. To describe sexual function and associated factors before bariatric surgery. Ten U.S. clinical facilities. Before bariatric surgery, 2225 of 2458 Longitudinal Assessment of Bariatric Surgery-2 study participants (79% female, median age 45 years and median body mass index 46 kg/m 2 ) completed a survey about sexual function over the past month. Mixed effects ordinal logistic regression models were used to identify factors independently related to 4 domains of sexual function. One third of women (34%) and one quarter of men (25%) were not sexually active, alone or with a partner, in the past month. Twenty-six percent of women and 12% of men reported no sexual desire. Physical health limited sexual activity at least moderately in 38% of women and 44% of men. About one half of the women (49%) and the men (54%) were moderately or very dissatisfied with their sexual life. Among women, older age, being Caucasian, urinary incontinence, depressive symptoms, and antidepressant medication use were associated with poorer sexual function in multiple domains. In men, older age, not being married, depressive symptoms, and antidepressant medication use were associated with poorer sexual function in multiple domains. Before bariatric surgery, approximately one half of women and men with severe obesity are dissatisfied with their sexual life. Older age, severity of depressive symptoms, and antidepressant medication use are associated with poorer sexual function in both sexes. Copyright © 2016. Published by Elsevier Inc.

Purpose Polymicrogyria (PMG) is an epileptogenic malformation of cortical development. We describe the clinical epilepsy and imaging features of a large cohort with PMG-related epilepsy. Methods Participants were recruited through the Epilepsy Phenome/Genome Project, a multi-center collaborative effort to collect detailed phenotypic data on individuals with epilepsy. We reviewed phenotypic data from participants with epilepsy and PMG. Key Findings We identified 87 participants, 43 female and 44 male, with PMG and epilepsy. Median age of seizure onset was 3 years (range <1 month-37 years). Most presented with focal epilepsy (87.4%), some in combination with seizures generalized from onset (23.0%). Focal seizures with dyscognitive features were most common (54.3%). Of those presenting with generalized seizure types, infantile spasms were most prevalent (45.2%). The most common topographic pattern was perisylvian PMG (77.0%), of which the majority was bilateral (56.7%). Generalized PMG presented with an earlier age of seizure onset (median age of 8 months) and an increased prevalence of developmental delay prior to seizure onset (57.1%). Of the focal, unilateral and asymmetric bilateral groups where PMG was more involved in one hemisphere, the majority (71.4%) of participants had seizures that lateralized to the same hemisphere as the PMG or the hemisphere with greater involvement. Significance Participants with PMG had both focal and generalized onset of seizures. Our data confirm the involvement of known topographic patterns of PMG and suggest that more extensive distributions of PMG present with an earlier age of seizure onset and increased prevalence of developmental delay prior to seizure onset.

In this study, we examined differences in inpatient costs, length of stay, and in-hospital mortality between hospitalizations for patients with and without sickle cell disease (SCD) undergoing high-volume surgical procedures. We used Clinical Classification Software (CCS) codes to identify discharges in the 2002–2005 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project for patients who had undergone either cholecystectomy or hip replacement. We limited the non-SCD cohort to hospitals where patients with SCD had undergone the same procedure. We compared inpatient outcomes using summary statistics and generalized linear regression analysis to adjust for patient, hospital, and procedural characteristics. Overall, the median age of surgical patients with SCD was more than 3 decades less than the median age of patients without SCD undergoing the same procedure. In recognition of the age disparity, we limited the analyses to patients aged 18 to 64 years. Nonetheless, patients with SCD undergoing cholecystectomy or hip replacement were 12.1 and 14.4 years younger, had inpatient stays that were 73% and 82% longer, and incurred costs that were 46% and 40% higher per discharge than patients without SCD, respectively. Inpatient mortality for these procedures was low, approximately 0.6% for cholecystectomy and 0.2% for hip replacement, and did not differ significantly between patients with and without SCD. Multivariable regression analyses revealed that higher inpatient costs among patients with SCD were primarily attributable to longer hospital stays. Patients with SCD who underwent cholecystectomy or hip replacement required more health care resources than patients without SCD. PMID:19787790

Osteonecrosis of the femoral head (ONFH) is a prevalent complication of sickle cell disease (SCD) that has not been well described in population-based cohort studies. Using California's Office of Statewide Planning and Development discharge databases (1991-2013), we estimated the cumulative incidence of ONFH after accounting for the competing risk of death and used a multivariable Cox proportional hazards regression to identify factors associated with ONFH diagnosis. We also calculated rates of readmissions to the hospital or emergency department within 30 to 90 days of hip replacement surgery. Of the 6237 patients in our SCD cohort, 22% (n = 1356) developed ONFH at a median age of 27 years, and 23% (n = 308) of the patients with ONFH underwent hip replacement surgery at a median age of 36 years. The cumulative incidence of ONFH to age 30 years was higher among SCD patients with more severe disease (24%; vs 8% in less severe) and those with antecedent acute chest syndrome (ACS) (18%; vs 8% without prior history of ACS). From 2003 to 2013, SCD patients with more severe disease (hazard ratio [HR], 2.77; 95% confidence interval [CI], 2.38-3.23) or with antecedent ACS (HR, 1.61; CI, 1.35-1.91) were more likely to develop ONFH. Twenty-seven percent of post-hip surgery patients were readmitted within 30 days, mostly for painful vaso-occlusive crises. ONFH is a common SCD complication that increases with age; ongoing studies into prevention and effective nonsurgical interventions for SCD-induced osteonecrosis must remain a high research priority.

Parker, Brendan T.; Marco, Catherine

2014-01-01

Introduction Managing a patient’s expectations in the emergency department (ED) environment is challenging. Previous studies have identified several factors associated with ED patient satisfaction. Lengthy wait times have shown to be associated with dissatisfaction with ED care. Understanding that patients are inaccurate at their estimation of wait time, which could lead to lower satisfaction, provides administrators possible points of intervention to help improve accuracy of estimation and possibly satisfaction with the ED. This study was undertaken to examine the accuracy of patient estimates of time periods in an ED and identify factors associated with accuracy. Method In this prospective convenience sample survey at UTMC ED, we collected data between March and July 2012. Outcome measures included duration of each phase of ED care and patient estimates of these time periods. Results Among 309 participants, the majority underestimated the total length of stay (LOS) in the ED (median difference −7 minutes (IQR −29-12)). There was significant variability in ED LOS (median 155 minutes (IQR 75–240)). No significant associations were identified between accuracy of time estimates and gender, age, race, or insurance status. Participants with longer ED LOS demonstrated lower patient satisfaction scores (p<0.001). Conclusion Patients demonstrated inaccurate time estimates of ED treatment times, including total LOS. Patients with longer ED LOS had lower patient satisfaction scores. PMID:24672606

Background Shigella is a leading cause of childhood diarrhea mortality in sub-Saharan Africa. Current World Health Organization guidelines recommend antibiotics for children in non cholera-endemic areas only in the presence of dysentery, a proxy for suspected Shigella infection. Methods To assess the sensitivity and specificity of the syndromic diagnosis of Shigella-associated diarrhea, we enrolled children aged 6 months to 5 years presenting to 1 of 3 Western Kenya hospitals between November 2011 and July 2014 with acute diarrhea. Stool samples were tested using standard methods for bacterial culture and multiplex polymerase chain reaction for pathogenic Escherichia coli. Stepwise multivariable logit models identified factors to increase the sensitivity of syndromic diagnosis. Results Among 1360 enrolled children, median age was 21 months (interquartile range, 11–37), 3.4% were infected with human immunodeficiency virus, and 16.5% were stunted (height-for-age z-score less than −2). Shigella was identified in 63 children (4.6%), with the most common species being Shigella sonnei (53.8%) and Shigella flexneri (40.4%). Dysentery correctly classified 7 of 63 Shigella cases (sensitivity, 11.1%). Seventy-eight of 1297 children without Shigella had dysentery (specificity, 94.0%). The combination of fecal mucous, age over 23 months, and absence of excessive vomiting identified more children with Shigella-infection (sensitivity, 39.7%) but also indicated antibiotics in more children without microbiologically confirmed Shigella (specificity, 82.7%). Conclusions Reliance on dysentery as a proxy for Shigella results in the majority of Shigella-infected children not being identified for antibiotics. Field-ready rapid diagnostics or updated evidence-based algorithms are urgently needed to identify children with diarrhea most likely to benefit from antibiotic therapy. PMID:26407270

To describe clinical, laboratory, microbiological features, and outcomes of necrotizing fasciitis. From January 1, 2004 to December 31, 2011, 115 patients (79 males, 36 females) diagnosed with necrotizing fasciitis were admitted to Mackay Memorial Hospital in Taitung. Demographic data, clinical features, location of infection, type of comorbidities, microbiology and laboratory results, and outcomes of patients were retrospectively analyzed. Among 115 cases, 91 survived (79.1%) and 24 died (20.9%). There were 67 males (73.6%) and 24 females (26.4%) with a median age of 54 years (inter-quartile ranges, 44.0-68.0 years) in the survival group; and 12 males (50%) and 12 females (50%) with a median age of 61 years (inter-quartile ranges, 55.5-71.5 years) in the non-surviving group. The most common symptoms were local swelling/erythema, fever, pain/tenderness in 92 (80%), 87 (76%) and 84 (73%) patients, respectively. The most common comorbidies were liver cirrhosis in 54 patients (47%) and diabetes mellitus in 45 patients (39%). A single organism was identified in 70 patients (61%), multiple pathogens were isolated in 20 patients (17%), and no microorganism was identified in 30 patients (26%). The significant risk factors were gender, hospital length of stay, and albumin level. Necrotizing fasciitis, although not common, can cause notable rates of morbidity and mortality. It is important to have a high index of suspicion and increase awareness in view of the paucity of specific cutaneous findings early in the course of the disease. Prompt diagnosis and early operative debridement with adequate antibiotics are vital. Copyright © 2013 Elsevier Editora Ltda. All rights reserved.

The prognosis of amyloidosis is known to depend heavily on cardiac function and may be improved by identifying patients at highest risk for adverse cardiac events. Identify predictors of mortality in patients with cardiac light-chain amyloidosis (AL), hereditary transthyretin amyloidosis (m-TTR), or wild-type transthyretin amyloidosis (WT-TTR) to prompt physician to refer these patients to dedicated centers. Observational study. About 266 patients referred for suspected cardiac amyloidosis (CA) in two French university centers were included. About 198 patients had CA (AL = 118, m-TTR = 57, and WT-TTR = 23). Their median (25th-75th percentile) age, NT-proBNP left ventricular ejection fraction were, respectively, 68 years (59-76), 2339 pg mL -1 (424-5974), and 60% (48-66). About 31% were in NYHA class III-IV. Interventricular septal thickness was greater in the m-TTR and WT-TTR groups than in the AL group (p < 0.0001). Median follow-up in survivor was 26 months (15-44) and 87 (44%) patients died. By multivariate analysis, independent predictors of mortality for AL amyloidosis were the following: age, cardiac output and NT-proBNP; for TTR amyloidosis was: NT-proBNP. When all amyloidosis were combined NT-proBNP, low cardiac output and pericardial effusion were independently associated with mortality. NT-proBNP is a strong prognosticator in the three types of cardiac amyloidosis. High NT-proBNP, low cardiac output, and pericardial effusion at the time of screening should prompt physician to refer the patients to amyloidosis referral center.

Purpose To perform usability testing of a binocular optical coherence tomography (OCT) prototype to predict its function in a clinical setting, and to identify any potential user errors, especially in an elderly and visually impaired population. Methods Forty-five participants with chronic eye disease (mean age 62.7 years) and 15 healthy controls (mean age 53 years) underwent automated eye examination using the prototype. Examination included ‘whole-eye' OCT, ocular motility, visual acuity measurement, perimetry, and pupillometry. Interviews were conducted to assess the subjective appeal and ease of use for this cohort of first-time users. Results All participants completed the full suite of tests. Eighty-one percent of the chronic eye disease group, and 79% of healthy controls, found the prototype easier to use than common technologies, such as smartphones. Overall, 86% described the device to be appealing for use in a clinical setting. There was no statistically significant difference in the total time taken to complete the examination between participants with chronic eye disease (median 702 seconds) and healthy volunteers (median 637 seconds) (P = 0.81). Conclusion On their first use, elderly and visually impaired users completed the automated examination without assistance. Binocular OCT has the potential to perform a comprehensive eye examination in an automated manner, and thus improve the efficiency and quality of eye care. Translational Relevance A usable binocular OCT system has been developed that can be administered in an automated manner. We have identified areas that would benefit from further development to guide the translation of this technology into clinical practice. PMID:28824827

Individual factors associated with L- and H-type Bovine Spongiform Encephalopathy in France

PubMed Central

2012-01-01

Background Cattle with L-type (L-BSE) and H-type (H-BSE) atypical Bovine Spongiform encephalopathy (BSE) were identified in 2003 in Italy and France respectively before being identified in other countries worldwide. As of December 2011, around 60 atypical BSE cases have currently been reported in 13 countries, with over one third in France. While the epidemiology of classical BSE (C-BSE) has been widely described, atypical BSEs are still poorly documented, but appear to differ from C-BSE. We analysed the epidemiological characteristics of the 12 cases of L-BSE and 11 cases of H-BSE detected in France from January 2001 to late 2009 and looked for individual risk factors. As L-BSE cases did not appear to be homogeneously distributed throughout the country, two complementary methods were used: spatial analysis and regression modelling. L-BSE and H-BSE were studied separately as both the biochemical properties of their pathological prion protein and their features differ in animal models. Results The median age at detection for L-BSE and H-BSE cases was 12.4 (range 8.4-18.7) and 12.5 (8.3-18.2) years respectively, with no significant difference between the two distributions. However, this median age differed significantly from that of classical BSE (7.0 (range 3.5-15.4) years). A significant geographical cluster was detected for L-BSE. Among animals over eight years of age, we showed that the risk of being detected as a L-BSE case increased with age at death. This was not the case for H-BSE. Conclusion To the best of our knowledge this is the first study to describe the epidemiology of the two types of atypical BSE. The geographical cluster detected for L-BSE could be partly due to the age structure of the background-tested bovine population. Our regression analyses, which adjusted for the effect of age and birth cohort showed an age effect for L-BSE and the descriptive analysis showed a particular age structure in the area where the cluster was detected. No birth cohort effect was evident. The relatively small number of cases of atypical BSE and the few individual data available for the tested population limited our analysis to the investigation of age and cohort effect only. We conclude that it is essential to maintain BSE surveillance to further elucidate our findings. PMID:22647660

Over the last 2 decades, there has been growing interest in research on the mortality of domesticated pets. These studies relied on an effective data-collecting system. During 2012-2014, a real-time reporting system was designed for mortality data in owned dogs and cats. The present retrospective study aimed to report on the causes of death (CODs) or reasons for euthanasia (RFEs) in domesticated dogs in Taiwan, and to investigate CODs/RFEs segregated by demographic variables. Data from 2306 domesticated dogs were acquired during the 3-year period in the present study. The median age at death of the study population was 10.2 years (median interquartile range 7.0-14.0; range 0.0-25.0). Crossbred, female, and neutered dogs showed greater ages at death than other groups. The most common COD/RFE was neoplasia, followed by multiple organ involvement (MOI) and cardiovascular diseases. Segregated by cut-off ages, the most common COD/RFE was infection among dogs younger than 3 years or 1year, and neoplasia among dogs at or older than 3 years or 1year of age; the most common COD/RFE was neoplasia among dogs younger than median age, and MOI among dogs at or older than median age. Segregated by geographic variables, the ranking and frequency of CODs/RFEs displayed different patterns between the capital city/non-capital areas, and among areas stratified by human population densities. The study provides various insights into age at death and CODs/RFEs in owned-dog population in Taiwan, and provides new directions for future research. Copyright © 2017 Elsevier B.V.

Stage and age at diagnosis are important prognostic factors for patients with colorectal cancer. However, the proportion cured by stage and age is unknown in England. This population-based study includes 29,563 adult patients who were diagnosed and registered with colorectal cancer during 1997-2004 and followed till 2007 in North West England. Multiple imputation was used to provide more reliable estimates of stage at diagnosis, when these data were missing. Cure mixture models were used to estimate the proportion 'cured' and the median survival of the uncured by age and stage. For both colon and rectal cancer the proportion of patients cured and median survival time of the uncured decreased with advancing stage and increasing age. Patients aged under 65 years had the highest proportion cured and longest median survival of the uncured. Cure of colorectal cancer patients is dependent on stage and age at diagnosis with younger patients or those with less advanced disease having a better prognosis. Further efforts are required, in order to reduce the proportion of patients presenting with stage III and IV disease and ultimately increase the chance of cure. Copyright © 2012 Elsevier Ltd.

To quantify median nerve characteristics before and after strenuous wheelchair propulsion and relate them to symptoms of carpal tunnel syndrome (CTS). We hypothesized that persons with and without symptoms of CTS would have significantly different nerve characteristics at baseline and after propulsion. A repeated-measures design was used to obtain ultrasound images of the median nerve at 3 levels of the wrist (radius, pisiform, and hamate) before and after wheelchair propulsion. Investigators were blinded to subject history related to CTS. The 2007 and 2008 National Veterans Wheelchair Games and the Human Engineering Research Laboratories. Fifty-four participants between the ages of 18 and 65 years with a nonprogressive disability who used a manual wheelchair as their primary means of mobility completed this study. Participants completed questionnaires regarding demographics and the presence and severity of symptoms of CTS. Ultrasound images of the median nerve were obtained before and after a 15-minute strenuous wheelchair-propulsion task. Baseline values and post-propulsion changes were determined for median nerve cross-sectional area, flattening ratio, and swelling ratio. Differences in median nerve variables between symptomatic and asymptomatic groups were assessed. No significant differences between symptom groups were identified at baseline; however, persons with symptoms of CTS showed a significantly different percent change from baseline compared with the asymptomatic participants for cross-sectional area at pisiform (P = .014) and flattening ratio at hamate (P = .022), and they showed a strong trend toward a difference in swelling ratio (P = .0502). For each of these variables, the change in the symptomatic group was in the opposite direction of the change in the asymptomatic group. We found several median nerve responses to wheelchair propulsion associated with symptoms of CTS. These responses occurred even though no baseline ultrasound difference was found based on symptoms. Future research is necessary to determine how propulsion characteristics (ie, force, repetition, and posture) affect the median nerve response.

A lifespan approach was used to evaluate age at menopause, and determinants of surgical and natural menopause, in the multi-ethnic community of Hilo, Hawaii. Participants aged 40-60 years (n=898) were drawn from a larger, randomly generated sample recruited by postal questionnaires. Median age at natural menopause was computed by probit analysis. Logistic regression analysis was applied to examine determinants of hysterectomy, and Cox regression analysis was used to examine risk factors for an earlier age at menopause. History of hysterectomy, age at menopause. Frequency of hysterectomy was 19.2% at a mean age of 40.5 years. The likelihood of hysterectomy increased with older ages, lower education, mixed ancestry, having been overweight at age 30, and married 20 years prior to survey. Median age at natural menopause was 53.0 years. Smoking and not being married 10 years before survey were associated with an earlier age at menopause. Median age at menopause was later than the national average. Ethnicity and education were determinants of hysterectomy, but not associated with age at natural menopause. Events later in the lifespan (e.g., smoking and not being married 10 years prior to the survey) were more important than earlier events (e.g., childhood residence) in relation to age at menopause. The timing of weight gain and marital status appear to be important in relation to surgical menopause, and the timing of marital status appears to be important in relation to the timing of natural menopause.

Gastric intestinal metaplasia (GIM) is a common finding from routine endoscopies. Although GIM is an early step in gastric carcinogenesis, there is controversy regarding routine surveillance of patients with GIM in regions with a low prevalence of gastric cancer. We aimed to determine the incidence of gastric cancer among patients with GIM and risk factors for gastric cancer. We performed a retrospective cohort study of patients from the Kaiser Permanente Southern California region diagnosed with GIM from 2000 through 2011. GIM was identified by a keyword search of pathology reports; gastric cancer cases were identified by cross-reference with an internal cancer registry. The incidence of gastric cancer in patients with GIM (n = 923; median age at diagnosis, 68 y) was compared with that of an age- and sex-matched reference population (controls). Risk factors such as ethnicity, smoking status, history of Helicobacter pylori infection, and family history of gastric cancer were evaluated by individual Cox proportional hazards regression. We then performed a second case-cohort study to evaluate the risk of gastric cancer based on the location and extent of GIM. The median duration of follow-up evaluation was 4.6 years (interquartile range, 3.0-6.7 y). We identified 25 patients with GIM who developed gastric cancers. Seventeen cases of cancer were diagnosed at the same time as the diagnosis of GIM. Eight cases of cancer were identified within a median time period of 4.6 years after a diagnosis of GIM (interquartile range, 2-5.7 y). The overall incidence rate for the cohort was 1.72 (95% confidence interval, 0.74-3.39). Among the risk factors evaluated, only family history (hazard ratio, 3.8; 95% confidence interval, 1.5-9.7; P = .012) and extent of GIM (odds ratio, 9.4; 95% confidence interval, 1.8-50.4) increased the risk for gastric cancer. The incidence rate for gastric cancer in patients with a positive family history was 8.12 (95% confidence interval, 1.67-23.73). In an analysis of patients with GIM listed in the Kaiser Permanente Southern California database, 2.7% were diagnosed with gastric cancer; almost 70% of cases of gastric cancer were detected at the time of GIM diagnosis. Family history and extensive metaplasia were associated with an increased risk of subsequent gastric cancer. Targeted surveillance of patients with these criteria could increase early detection of gastric cancer. Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.

A small proportion of infants with oesophageal atresia (OA) are thought to have a proximal tracheoesophageal fistula (TOF). Failure to recognize these can hamper mobilization of the upper pouch and lead to life-threatening episodes of aspiration once oral feeding starts. We reviewed our experience of upper pouch fistulae to identify characteristic features of proximal TOF. A retrospective review of TOF/OA patient notes and bronchoscopy photographs and videos, identified from our database from 01/01/2006 to 12/31/2015, was performed. Eight (6.1%) infants were identified (M:F 5:3) from a total population of 131 newly diagnosed TOF/OA infants during the period. Their median gestational age was 33 (range 28-39) weeks, and median birth weight was 1647g (range 1100-3400g). Five were initially diagnosed with pure OA and 3 with a distal TOF. All patients underwent rigid bronchoscopy at the initial surgery but only one proximal fistula was identified. The 7 missed proximal fistulae were subsequently found either during on-table oesophagograms for gap assessment (n=2), at the time of thoracotomy when mobilizing the upper pouch (n=3), or during subsequent bronchoscopy for symptoms post OA repair (n=2). Two patients needed a further operation to divide the fistula. Review of the bronchoscopy videos identified four characteristic differences between upper and lower pouch fistulae. Proximal fistulae are found just distal to the vocal cords, are very small, often no more than a pit, do not open and close with ventilation, and are best identified by insufflation of the esophagus. Upper pouch fistulae are relatively easy to miss because of different characteristics compared with H-type or distal fistulae that have not previously been mentioned in the literature. level IV.

Atrial fibrillation (AF) is the most common cardiac dysrhythmia associated with significant morbidity and mortality. Several small studies have reported that low serum total testosterone (TT) levels were associated with a higher incidence of AF. In contrast, it is also reported that anabolic steroid use is associated with an increase in the risk of AF. To date, no study has explored the effect of testosterone normalization on new incidence of AF after testosterone replacement therapy (TRT) in patients with low testosterone. Using data from the Veterans Administrations Corporate Data Warehouse, we identified a national cohort of 76 639 veterans with low TT levels and divided them into 3 groups. Group 1 had TRT resulting in normalization of TT levels (normalized TRT), group 2 had TRT without normalization of TT levels (nonnormalized TRT), and group 3 did not receive TRT (no TRT). Propensity score-weighted stabilized inverse probability of treatment weighting Cox proportional hazard methods were used for analysis of the data from these groups to determine the association between post-TRT levels of TT and the incidence of AF. Group 1 (40 856 patients, median age 66 years) had significantly lower risk of AF than group 2 (23 939 patients, median age 65 years; hazard ratio 0.90, 95% CI 0.81-0.99, P =0.0255) and group 3 (11 853 patients, median age 67 years; hazard ratio 0.79, 95% CI 0.70-0.89, P =0.0001). There was no statistical difference between groups 2 and 3 (hazard ratio 0.89, 95% CI 0.78- 1.0009, P =0.0675) in incidence of AF. These novel results suggest that normalization of TT levels after TRT is associated with a significant decrease in the incidence of AF. © 2017 The Authors.

Anal adenocarcinoma (AA) represents 5% to 10% of anal cancer. Little is known about its natural history and prognosis. Using population-based data, we defined the outcomes of AA relative to other anorectal malignancies. We analyzed the Surveillance, Epidemiology, and End Results 18 database to identify patients ≥ 18 years old with AA, squamous cell carcinoma of the anus (SCCA), and rectal adenocarcinoma (RA) diagnosed between 1990 and 2011. Median overall survival (OS), 1-year, 3-year, 5-year, and 10-year OS were computed using actuarial methods. The log rank test was used to estimate the difference between Kaplan-Meier survival curves. A Cox proportional hazard regression model was used to adjust the effects of other covariates on survival, including age, year diagnosed, sex, stage, surgery, and radiation. Of 57,369 cases, 0.8% (n = 462) were patients with AA, 87.8% (n = 50,382) were patients with RA, and 11.4% (n = 6525) were patients with SCCA. The median age for AA was 69 years (range, 20-96 years), 66 years (range, 18-103 years) for RA, and 66 years (range, 14-104 years) for SCCA. The median OS was significantly lower for AA (33 months), compared with SCCA (118 months) and RA (68 months) (P < .01). In multivariate analysis, AA had a worse prognosis compared with SCCA (hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.59-0.75; P < .01) and RA (HR, 0.68; 95% CI, 0.61-0.77; P < .01), after adjusting for age, sex, race, stage, grade, radiation, and surgery. There was a strong trend for improved survival among patients who received radical surgery (HR, 0.71; 95% CI, 0.51-1.00; P = .05). AA confers a significantly worse prognosis than SCCA and RA.

Kozak, Kevin R.; Hamidi, Maryam; Manning, Matthew

2012-06-01

Purpose: This study examines the management and outcomes of muscle-invasive bladder cancer in the United States. Methods and Materials: Patients with muscle-invasive bladder cancer diagnosed between 1988 and 2006 were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Patients were classified according to three mutually exclusive treatment categories based on the primary initial treatment: no local management, radiotherapy, or surgery. Overall survival was assessed with Kaplan-Meier analysis and Cox models based on multiple factors including treatment utilization patterns. Results: The study population consisted of 26,851 patients. Age, sex, race, tumor grade, histology, and geographic location were associated withmore » differences in treatment (all p < 0.01). Patients receiving definitive radiotherapy tended to be older and have less differentiated tumors than patients undergoing surgery (RT, median age 78 years old and 90.6% grade 3/4 tumors; surgery, median age 71 years old and 77.1% grade 3/4 tumors). No large shifts in treatment were seen over time, with most patients managed with surgical resection (86.3% for overall study population). Significant survival differences were observed according to initial treatment: median survival, 14 months with no definitive local treatment; 17 months with radiotherapy; and 43 months for surgery. On multivariate analysis, differences in local utilization rates of definitive radiotherapy did not demonstrate a significant effect on overall survival (hazard ratio, 1.002; 95% confidence interval, 0.999-1.005). Conclusions: Multiple factors influence the initial treatment strategy for muscle-invasive bladder cancer, but definitive radiotherapy continues to be used infrequently. Although patients who undergo surgery fare better, a multivariable model that accounted for patient and tumor characteristics found no survival detriment to the utilization of definitive radiotherapy. These results support continued research into bladder preservation strategies and suggest that definitive radiotherapy represents a viable initial treatment strategy for those who wish to attempt to preserve their native bladder.« less

Pediatric heart transplant recipients undergo a variety of radiologic tests with the attendant risk of exposure to ionizing radiation. We sought to quantify and describe the cumulative exposure to all forms of medical radiation during the first year after pediatric heart transplantation and identify factors associated with higher exposure. Pediatric patients who received a heart transplant between January 2009 and May 2012 with follow-up at our institution were retrospectively reviewed. Patients were included if they survived through 1 year and the first coronary angiography. All medical testing using ionizing radiation performed during follow-up was compiled, and exposures were converted to effective dose (mSv). Included were 31 patients who underwent heart transplantation at a median age of 13.6 years (range, 0.3-18.3 years). The median number of radiologic tests performed was 38 (range, 18-154), including 8 catheterizations (range, 2-12), and 28 X-ray images (range, 11-135). Median cumulative effective dose was 53.5 mSv (range, 10.6-153.5 mSv), of which 91% (range, 34%-98%) derived from catheterizations, 31% (range, 8%-89%) of the exposure occurred during the transplant admission, 59% (range, 11%-88%) during planned follow-up, and 3% (0%-56%) during unplanned follow-up. Older age at transplant was a risk factor for increased exposure (p = 0.006). When adjusted for age, a trend toward increased exposure was shown for congenital heart disease as the indication for transplant (p = 0.08), pre-sensitization (p = 0.12), and positive crossmatch (p = 0.09). Pediatric heart transplant patients are exposed to significant amounts of ionizing radiation during the first post-transplant year, most during scheduled catheterization. As survival improves, considering the long-term risks associated with these levels of exposure is important. Copyright © 2014 International Society for Heart and Lung Transplantation.

We previously showed a survival benefit of the implantable cardioverter defibrillator (ICD) in males with arrhythmogenic right ventricular cardiomyopathy caused by a p.S358L mutation in TMEM43. We present long-term data (median follow-up 8.5 years) after ICD for primary (PP) and secondary prophylaxis in males and females, determine whether ICD discharges for ventricular tachycardia/ventricular fibrillation were equivalent to an aborted death, and assess relevant clinical predictors. We studied 24 multiplex families segregating an autosomal dominant p.S358L mutation in TMEM43. We compared survival in 148 mutation carriers with an ICD to 148 controls matched for age, sex, disease status, and family. Of 80 male mutation carriers with ICDs (median age at implantation 31 years), 61 (76%) were for PP; of 68 females (median age at implantation 43 years), 66 (97%) were for PP. In males, irrespective of indication, survival was better in the ICD groups compared with control groups (relative risk 9.3 [95% confidence interval 3.3-26] for PP and 9.7 [95% confidence interval 3.2-29.6] for secondary prophylaxis). For PP females, the relative risk was 3.6 (95% confidence interval 1.3-9.5). ICD discharge-free survival for ventricular tachycardia/ventricular fibrillation ≥ 240 beats per minute was equivalent to the control survival rate. Ectopy (≥ 1000 premature ventricular complexes/24 hours) was the only independent clinical predictor of ICD discharge in males, and no predictor was identified in females. ICD therapy is indicated for PP in postpubertal males and in females ≥ 30 years with the p.S358L TMEM43 mutation. ICD termination of rapid ventricular tachycardia/ventricular fibrillation can reasonably be considered an aborted death. © 2016 American Heart Association, Inc.

Worldwide, most neonates who survive prematurity and serious illness reside in low-resource settings where developmental outcome data and follow-up care are limited. This study aimed to assess in Fiji, a low-resource Pacific setting, prevalence and risk factors for moderate to severe neurodevelopmental impairment (NDI) in early childhood among high-risk neonates compared with controls. Retrospective cohort study comparing long-term outcomes for high-risk neonatal intensive care unit patients (n=149) compared with matched term, normal birth weight neonates (n=147) discharged from Colonial War Memorial Hospital between November 2008 and April 2010. NDI was defined as one or more of cerebral palsy, moderate to severe hearing or visual impairment, or global developmental delay using Bayley Scales of Infant and Toddler Development Third Edition (ie, score <70 in ≥1 of cognitive, language or motor domains). At median (IQR) age 36.1 (28.3, 38.0) months, prevalence of moderate to severe NDI % (95% CI, n) in high-risk and control groups was 12 (5 to 17, n=13) and 5 (2 to 12, n=5), respectively, an increased risk ratio (95% CI) of 2.7 (0.8 to 8.9). Median gestational age (weeks (median, IQR)) in the high-risk group was 37.5 (34-40) weeks. Among high-risk neonates, gestational age, birth weight, asphyxia, meningitis and/or respiratory distress were significantly associated with risk of NDI. Prevalence of NDI was high among this predominantly term high-risk neonatal cohort compared with controls. Results, including identified risk factors, inform efforts to strengthen quality of care and models of follow-up for high-risk neonates in this low-resource setting. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

We aimed to evaluate the clinicopathologic characteristics, immunohistochemical expression and prognostic factors of patients with primary gastrointestinal stromal tumors (GISTs). Data from 2,570 consecutive GIST patients from four medical centers in China (January 2001-December 2015) were reviewed. Survival curves were constructed by the Kaplan-Meier method, and Cox regression models were used to identify independent prognostic factors. Of the included patients, 1,375 (53.5%) were male, and the patient age range was 18 to 95 (median, 58) years. The tumors were mostly found in the stomach (64.5%), small intestine (25.1%) and colorectal region (5.1%). At the time of diagnosis, the median tumor size was 4.0 (range: 0.1-55.0) cm, and the median mitotic index per 50 high power fields (HPFs) was 3 (range: 0-254). Of the 2,168 resected patients, 2,009 (92.7%) received curative resection. According to the modified National Institutes of Health (NIH) classification, 21.9%, 28.9%, 14.1% and 35.1% were very low-, low-, intermediate- and high-risk tumors, respectively. The rate of positivity was 96.4% for c-Kit, 87.1% for CD34, 96.9% for delay of germination 1 (DOG-1), 8.0% for S-100, 31.0% for smooth muscle actin (SMA) and 5.1% for desmin. However, the prognostic value of each was limited. Multivariate analysis showed that age, tumor size, mitotic index, tumor site, occurrence of curative resection and postoperative imatinib were independent prognostic factors. Furthermore, we found that high-risk patients benefited significantly from postoperative imatinib (P<0.001), whereas intermediate-risk patients did not (P=0.954). Age, tumor size, mitotic index, tumor site, occurrence of curative resection and postoperative imatinib were independent prognostic factors in patients with GISTs. Moreover, determining whether intermediate-risk patients can benefit from adjuvant imatinib would be of considerable interest in future studies.
