Maternal pregnancy C-reactive protein predicts offspring birth size and body composition in metropolitan Cebu, Philippines.

The gestational milieu is an important influence on fetal development and long-term disease risk. Here we assess relationships between maternal pregnancy inflammation, indicated by C-reactive protein (CRP), and offspring anthropometric outcomes measured soon after birth. Data come from female participants (n=327, age 24.4-30.2 years) in a longitudinal study located in Metropolitan Cebu, Philippines. Between 2009 and 2014, pregnancy interviews (n=429) were conducted during which questionnaire and anthropometric data were obtained along with dried blood spot cards for CRP measurement. Offspring body weight, length, head circumference and five skinfold thickness measures were obtained soon after birth. Maternal pregnancy CRP was borderline (-1.11±0.64 days/log-mg/l; P<0.1) inversely related to gestational age at delivery, but did not increase the likelihood of preterm delivery. After adjusting for maternal pre-pregnancy body mass index, height, pregnancy adiposity, age, parity and other covariates, CRP was significantly, inversely related to offspring body weight (-0.047±0.017 kg/log-mg/l), length (-0.259±0.092 cm/log-mg/l) and sum of skinfolds (-0.520±0.190 mm/log-mg/l) (all P<0.05), and borderline inversely related to offspring head circumference (-0.102±0.068 cm/log-mg/l; P<0.1). Notably, relationships were continuous across the full CRP range, and not limited to unusually high levels of inflammation. These findings point to an important role of maternal non-specific immune activation as a predictor of offspring birth outcomes. In light of evidence that early life microbial, nutritional and stress experiences influence adult inflammatory regulation, these findings point to inflammation as a potential pathway for the intergenerational transmission of maternal experience to offspring health.

Precision and accuracy of a new device (CNAPTM) for continuous non-invasive arterial pressure monitoring: assessment during general anaesthesia.

BACKGROUND: Continuous non-invasive arterial pressure measured with CNAP (CNAP) has been shown to be superior to intermittent oscillometric measurements during procedural sedation and spinal anaesthesia. We assessed the performance of CNAP during general anaesthesia by analysis of agreement with invasive measurements of arterial pressure (AP). METHODS: Eighty-eight patients undergoing elective abdominal surgery, cardio-, or neurosurgery were included in the study. Systolic, diastolic, and mean AP measured by an intra-arterial catheter in the radial artery (IAP) were compared with those obtained by CNAP from the same arm. Data were analysed to determine the precision (i.e. measurement error) and accuracy (i.e. systematic error) of beat-to-beat CNAP values with respect to IAP. Also, we compared the frequency of fast changes in AP (FCAP) and hypotension (IOH) by both methods. RESULTS: CNAP precision of 4.5, 3.1, and 3.2 mm Hg (systolic, diastolic, and mean AP, respectively) was not significantly different from IAP precision, and CNAP accuracy was +6.7, -5.6, and -1.6 mm Hg. The frequency of AP pairs having a difference within the calculated limits of agreement was 81%, 64%, and 76% for systolic, diastolic, and mean AP, respectively. The calculated limits of agreement were +/-17.6, +/-11.4, and +/-12.0 mm, Hg, respectively. CNAP and IAP detected simultaneously to 82.1% FCAP and to 84.6% IOH. CONCLUSIONS: CNAP provides real-time estimates of arterial pressure comparable with those generated by an invasive intra-arterial catheter system during general anaesthesia.

Executive functioning in high-IQ adults with ADHD.

BACKGROUND: To examine the association between psychological tests of executive functioning and functional outcomes among high-IQ adults with attention deficit hyperactivity disorder (ADHD). METHOD: Subjects were high-IQ adults with (n=64) and without ADHD (n=53). Subjects were administered a battery of neuropsychological tests assessing executive functioning. RESULTS: High-IQ adults with ADHD performed less well than those without ADHD on several psychological tests of executive functioning, including the Wisconsin Card Sorting Test (WCST), Stroop Color and Word Test, Rey-Osterrieth Complex Figure Test (ROCF), California Verbal Learning Test (CVLT) and an auditory continuous performance test (CPT). Test performance in the high-IQ adult ADHD group, however, was average. In the entire sample, performance on several tests of executive functioning including the ROCF and the CVLT were significant predictors of real-world functioning. CONCLUSIONS: High-IQ adults with ADHD perform less well on tests of executive functioning relative to high-IQ control participants. Performance on several tests of executive functioning was a significant predictor of functioning.

Is adult attention deficit hyperactivity disorder a valid diagnosis in the presence of high IQ?

BACKGROUND: Because the diagnosis of attention deficit hyperactivity disorder (ADHD) in higher education settings is rapidly becoming a contentious issue, particularly among patients with high IQs, we sought to assess the validity of diagnosing ADHD in high-IQ adults and to further characterize the clinical features associated with their ADHD. METHOD: We operationalized high IQ as having a full-scale IQ120. We identified 53 adults with a high IQ who did not have ADHD and 64 adults with a high IQ who met diagnostic criteria for ADHD. Groups did not differ on IQ, socio-economic status or gender. RESULTS: High-IQ adults with ADHD reported a lower quality of life, had poorer familial and occupational functioning, and had more functional impairments, including more speeding tickets, accidents and arrests. Major depressive disorder, obsessive-compulsive disorder and generalized anxiety disorder diagnoses were higher in high-IQ adults with ADHD. All other psychiatric co-morbidities, including antisocial personality disorder and substance abuse, did not differ between the two high-IQ groups. ADHD was more prevalent in first-degree relatives of adults with ADHD relative to controls. CONCLUSIONS: Our data suggest that adults with ADHD and a high IQ display patterns of functional impairments, familiality and psychiatric co-morbidities that parallel those found in the average-IQ adult ADHD population.

Neurocognitive impairment in unaffected siblings of youth with bipolar disorder.

BACKGROUND: There is growing evidence for the familiality of pediatric bipolar disorder (BPD) and its association with impairments on measures of processing speed, verbal learning and 'executive' functions. The current study investigated whether these neurocognitive impairments index the familial risk underlying the diagnosis. METHOD: Subjects were 170 youth with BPD (mean age 12.3 years), their 118 non-mood-disordered siblings and 79 non-mood-disordered controls. Groups were compared on a battery of neuropsychological tests from the Wechsler Intelligence Scales, the Stroop Color Word Test, the Wisconsin Card Sorting Test (WCST), the Rey-Osterrieth Complex Figure (ROCF), an auditory working memory Continuous Performance Test (CPT) and the California Verbal Learning Test-Children's Version (CVLT-C). Measures were factor analyzed for data reduction purposes. All analyses controlled for age, sex and attention-deficit/hyperactivity disorder (ADHD). RESULTS: Principal components analyses with a promax rotation yielded three factors reflecting: (1) processing speed/verbal learning, (2) working memory/interference control and (3) abstract problem solving. The CPT working memory measure with interference filtering demands (WM INT) was only administered to subjects aged > or =12 years and was therefore analyzed separately. BPD youth showed impairments versus controls and unaffected relatives on all three factors and on the WM INT. Unaffected relatives exhibited impairments versus controls on the abstract problem-solving factor and the WM INT. They also showed a statistical trend (p=0.07) towards worse performance on the working memory/interference control factor. CONCLUSIONS: Neurocognitive impairments in executive functions may reflect the familial neurobiological risk mechanisms underlying pediatric BPD and may have utility as endophenotypes in molecular genetic studies of the condition.

Stability of executive function deficits into young adult years: a prospective longitudinal follow-up study of grown up males with ADHD.

OBJECTIVE: Although individuals with attention deficit-hyperactivity disorder (ADHD) commonly exhibit deficits in executive functions that greatly increase the morbidity of the disorder, all available information on the subject is cross sectional. METHOD: Males (n = 85) 9-22 years with ADHD followed over 7 years into young adulthood were assessed on measures of sustained attention/vigilance, planning and organization, response inhibition, set shifting and categorization, selective attention and visual scanning, verbal and visual learning, and memory. A binary definition of executive function deficits (EFDs) was defined based on a subject manifesting at least two abnormal tests 1.5 standard deviations from controls. RESULTS: The majority of subjects maintained EFDs over time (kappa: 0.41, P < 0.001; sensitivity: 55%, specificity: 85%, positive predictive value: 69%, and negative predictive value: 75%). CONCLUSION: Considering the morbidity of EFDs, these findings stress the importance of their early recognition for prevention and early intervention strategies. EFDs are stable over time.

Giving patients 'perceived control' over psoriasis: advice for optimizing the physician-patient relationship.

Patients with psoriasis suffer from the effects of a chronic illness. One of the most bothersome aspects of the disease is a sense of loss of 'control.' 'Perceived control' is an important and well-studied psychological concept. The literature on perceived control offers guidance to help improve the physician-patient relationship and outcomes in chronic diseases such as psoriasis. Practical suggestions include the use of materials and other resources offered by patient advocacy groups (such as those from the National Psoriasis Foundation) and the development of a physician-patient relationship that gives the patient a sense of control of their disease.

Exploratory analysis and a stochastic model for humusdisintegration.

Ulrich (1981) supposes in the hypothesis of humusdisintegration that the balance between polymerisation and breakdown of organic material may be disturbed in chemically well buffered European forest soils. This new aspect of aluminium toxicity may cause nitrogen exceedance in forest ecosystems and subsequent seasonal nitrate output (Eichhorn and Hutterman, 1999). In a research program the substances in the seepage water are monitored in a small woodland in central Germany. We explore these multivariate data for examining possible influences on the process of humusdisintegration and its temporal evolution. As a result, a regression model for carbon is developed, which includes covariables, i.e., other substances, as well as spatial and temporal terms describing systematic variability. Especially iron and aluminium turn out to be very influential in the model. So far our work is a basic step for monitoring the seepage water data by means of stochastic modelling.

Online pattern recognition in intensive care medicine.

In intensive care physiological variables of the critical-ly ill are measured and recorded in short time intervals. The existing alarm systems based on fixed thresholds produce a large number of false alarms. Usually the change of a variable over time is more informative than one pathological value at a particular time point. Intelligent alarm systems which detect important changes within a physiological time series are needed for suitable bedside decision support. There are various approaches to modeling time-dependent data and also several methodologies for pattern detection in time series. We compare several methodologies de-signed for online detection of measurement artifacts, level changes, and trends for a proper classification of the patient s state by means of a comparative case-study.

[The aspiration and swallowing of foreign bodies. The management of the aspiration or swallowing of foreign bodies during dental treatment]. / Aspiration und Verschlucken von Fremdkörpern. Verhalten bei Aspiration oder Verschlucken von Fremdkörpern während der zahnärztlichen Behandlung.

The purpose of this article is to draw attention to the possible complications of foreign body ingestion or aspiration associated with dental treatment, especially oral implant treatment. A guide for the management of swallowed or inhaled objects is given. When the object cannot be coughed out, then it is mandatory to take frontal and lateral chest roentgenograms to identify the object's position in the intestinal system or in the tracheobronchial tree. In case of ingestion, attempts should be made to recover the foreign object by esophagoscopy. Aspirated foreign bodies should be removed within 24 hours. Acute obstruction can be life threatening and delaying the removal of foreign objects may make a bronchoscopy technically more difficult. The clinician must be aware of the complications involved in accidentally inhaling or ingesting foreign bodies during dental treatment. Patients at greater risk of swallowing or aspirating foreign objects need to be identified and extra preventive steps must be taken to avoid such complications.

Evaluation of magnetic resonance cholangiography in the management of bile duct stones.

HYPOTHESIS: Magnetic resonance cholangiography (MRC) offers the potential for accurate, noninvasive detection of common bile duct stones (CBDSs) before cholecystectomy, and for a consequent reduction in the incidence of preoperative negative diagnoses associated with endoscopic retrograde cholangiography (ERC). DESIGN: Prospective cohort study: MRC results were correlated with ERC (high-risk patients) or intraoperative cholangiography (moderate-risk patients). SETTING: A university hospital providing primary, secondary, and tertiary care. PATIENTS: Seventy patients with suspected CBDSs scheduled to undergo elective cholecystectomy between April 15, 1997, and September 30, 1998. Forty patients were considered at high risk and 30 at moderate risk for CBDSs, according to results of liver function tests and sonograms of the upper abdomen. MAIN OUTCOME MEASURES: Confirmation or exclusion of CBDSs by MRC was assessed by a panel of radiologists who were unaware of the ERC results. Results of ERC and intraoperative cholangiography were analyzed by the investigating gastroenterologists or surgeon. RESULTS: Results of MRC were positive for CBDSs in 21 (52%) of 40 high-risk patients, a finding confirmed by preoperative ERC in 19 (90%) of 21 patients. Results of MRC were positive for CBDSs in 6 (20%) of 30 moderate-risk patients, all of which were confirmed by intraoperative cholangiography. Finally, CBDSs were present in 19 (48%) of 40 high-risk patients and 6 (20%) of 30 moderate-risk patients (P = .02). Overall sensitivity and specificity of MRC were 100% and 95.6%, respectively; the positive and negative predictive values were 92.6% and 100%, respectively. CONCLUSIONS: Magnetic resonance cholangiography is a reliable, noninvasive method for the detection or exclusion of CBDSs, and seems to reduce the frequency of negative diagnoses associated with ERC. Magnetic resonance cholangiography revealed no CBDSs in 19 (48%) of 40 patients at high risk for CBDSs. Thus, MRC-based diagnosis has the potential to reduce the number of invasive preoperative diagnostic procedures and their associated risks and overall health care costs.

Dimension reduction for highdimensional online-monitoring data in intensive care.

Nowadays high dimensional data in intensive care medicine can be captured, stored, and retrieved with the help of clinical information systems. Intelligent alarm systems are needed for an adequate bedside decision support, in the course of which the detection of qualitative patterns in physiologic monitoring data such as outliers, level changes, or trends aims at a proper classification of the patients state. Statistical time series techniques have already been applied successfully to the analysis of single physiological variables. The simultaneous online analysis of the multivariate patient curve yields further challenges. We describe methods for reducing the dimension and for keeping the computational efforts necessary for monitoring low. We present preliminary results of an ongoing study on monitoring critically ill patients.

Cutaneous and psychosocial benefits of alpha hydroxy acid use.

Alpha hydroxy acids are used extensively by patients and consumers for restorative cutaneous purposes. The current study of 32 patients evaluated the clinical and psychosocial effects of this cosmetic therapy. After 12 weeks, significant clinical improvements were found for facial skin tone and fine wrinkling, as well as for patient-reported satisfaction with physical appearance and with marital or relationship quality.

Hemodynamic effects of the somatostatin analog lanreotide in humans: placebo-controlled, cross-over dose-ranging Echo-Doppler study.

Because of their vasoactive effects, somatostatin and its analogs are increasingly used in the management of complications of chronic liver diseases such as variceal bleeding. Postprandial hyperemia augments splanchnic blood flow, subsequently increasing portal pressure. The aim of this study was to explore effects of the somatostatin analog, lanreotide, on food-stimulated hemodynamic parameters in healthy human subjects. A dose-response curve was constructed in eight healthy male subjects in a placebo-controlled cross-over study. On 4 different days, either 0 (placebo), 50, 100, or 200 microg/h of lanreotide was infused intravenously in random order, starting at 45 minutes for 7 hours. On each day, a liquid test meal (Ensure plus, 1.5 kcal/mL) was perfused intraduodenally at a rate of 3 mL/min over 7 hours after a 45-minute basal period. Diastolic arterial pressure (dBP), heart rate (HR), superior mesenteric arterial (SMA) average flow velocity (SMA-V), SMA pulsatility index (SMA-PI), portal venous volume flow (PV-F), and renal artery (RA) resistance index (RA-RI) were measured on regular intervals (flows using Echo-Doppler technology). Lanreotide at all doses abolished food-stimulated splanchnic hyperemia both in the SMA and PV over 7 hours. The fall in dBP and increase in HR after food perfusion were blunted under lanreotide. Food as well as lanreotide did not modify RA-RI. In summary: 1) lanreotide inhibits food-induced splanchnic hyperemia in normal subjects; 2) in parallel, systemic hemodynamic alterations to food stimulation are abolished with lanreotide; and 3) renal vascular resistance is unchanged. Because of its persistent splanchnic vasoconstrictive effect, lanreotide should be tested in patients with portal hypertension.
