Sex differences in functional outcome after hospitalisation: A systematic review and meta-analysis.

The aims of this review were to determine: i) how many studies have examined global functioning outcomes from a psychiatric inpatient stay disaggregated by sex; and ii) if women have worse global functioning outcomes than men following an admission. A systematic review following PRISMA guidance and meta-analysis were conducted. Thirty-six studies met eligibility criteria for inclusion in the review. Of these, eleven papers provided sufficient data to conduct a meta-analysis of global functioning outcomes comparing men and women. Overall, differences between men and women were small. The meta-analysis revealed either no difference or a small significant difference in global functioning outcomes in favour of women, contrary to expectations. As many as 93% of otherwise eligible studies had to be excluded for not disaggregating data by sex. Women may have slightly superior functioning outcomes than men suggesting that inpatient services should be more heavily focused on applying principles of gender-informed care for men as well as women. The finding that so many potential studies had to be excluded for not reporting sex differences is consistent with other mental health literature and highlights a need for better reporting practices in relation to sex differences.

Child and adolescent psychiatrists' reported monitoring behaviors for second-generation antipsychotics.

OBJECTIVE: The number of children and adolescents (hereafter referred to as "children") who have been prescribed second-generation antipsychotics (SGAs) has increased over the last decade, but little is known about monitoring practices in pediatric patients who are vulnerable to adverse effects. We examined factors associated with psychiatrists' self-reported monitoring of children who were prescribed SGAs. METHODS: A survey was mailed to a national, randomly selected sample of 1600 child and adolescent psychiatrists from the American Medical Association mailing list. Using logistic regression, we tested whether psychiatrist characteristics, attitudes, and practice characteristics were associated with monitoring (baseline and/or periodic) the following: Patient history, height and weight, blood pressure, waist circumference, lipid and glucose levels, and electrocardiogram. RESULTS: Among the analytic sample of 308, at least two thirds reported monitoring patient history, height and weight, blood pressure, and fasting plasma lipids and glucose; 23% reported monitoring waist circumference; and 12% reported conducting an electrocardiogram. More than one third stated that they routinely monitored thyroid levels and more than half reported monitoring complete blood count and electrolytes/blood urea nitrogen. Psychiatrists reporting that they were able to measure vital signs on site were more likely to measure height and weight. Those who reported feeling comfortable conducting a physical examination were more likely to measure blood pressure. Those answering that the risk of metabolic syndrome was low were less likely to measure blood pressure and waist circumference. Being board certified and able to measure vital signs on site were associated with more monitoring of glucose and lipid levels. Conversely, years in practice and feeling that patients were nonadherent with blood work were associated with less monitoring of glucose and lipid levels. CONCLUSIONS: In this sample, inconsistent monitoring patterns of children prescribed SGAs were found. Efforts to communicate guidelines' evidence base and improve office capacity to measure and track adverse effects are needed to increase appropriate adverse effect monitoring in children who have been prescribed SGAs.

Variations in Physician Attitudes Regarding ADHD and Their Association With Prescribing Practices.

OBJECTIVE: The objective of this study was to test whether physicians' attitudes regarding the impact of ADHD on health-related quality of life (HRQL) explain differences in practices for prescribing psychostimulants in children. METHOD: In a cross-sectional survey, U.S.-based pediatricians and psychiatrists ("physicians") used the Paper-Standard Gamble--a widely used preference-based assessment of HRQL--to rate four vignettes describing ADHD health states of varying severity. Associations between standard gamble scores and questions about prescribing practices were analyzed using ordinal logistic regression. RESULTS: Surveys were mailed to 291 physicians; 127 (44%) returned complete forms. Lower standard gamble scores were associated with more emphasis on children's ADHD symptoms (p = .03) and less emphasis on parents' concerns about stimulant side effects (p = .03) when prescribing psychostimulants. CONCLUSION: Differences in physician perceptions of the severity of ADHD symptoms and in their emphasis on parental concerns about side effects may help explain variations in ADHD psychostimulant prescription patterns.

Component reductions in oxygen delivery generate variable haemodynamic and stress hormone responses.

BACKGROUND: In clinical practice, global oxygen delivery (DO2) is often considered as a whole; however pathological and adaptive responses after a decrease in individual constituents of the DO2 equation (cardiac output, haemoglobin, oxyhaemoglobin saturation) are likely to be diverse. We hypothesized that an equivalent decrease in DO2 after reductions in each separate component of the equation would result in different haemodynamic, tissue oxygenation, and stress hormonal responses. METHODS: Anaesthetized, fluid-resuscitated male Wistar rats were subjected to circulatory, anaemic, or hypoxic hypoxia (by haemorrhage, isovolaemic haemodilution, and breathing a hypoxic gas mix, respectively), produced either rapidly over 5 min or graded over 30 min, to a targeted 50% decrease in global oxygen delivery. Sham-operated animals acted as controls. Measurements were made of haemodynamics, skeletal muscle tissue oxygen tension, blood gas analysis, and circulating stress hormone levels. RESULTS: Whereas haemorrhage generated the largest decrease in cardiac output, and the greatest stress hormone response, haemodilution had the most marked effect on arterial pressure. In contrast, rapid hypoxaemia produced a minor impact on global haemodynamics yet induced the greatest decrease in regional oxygenation. A greater degree of hyperlactataemia was observed with graded insults compared with those administered rapidly. CONCLUSIONS: Decreasing global oxygen delivery, achieved by targeted reductions in its separate components, induces varying circulatory, tissue oxygen tension, and stress hormone responses. We conclude that not all oxygen delivery is the same; this disparity should be emphasized in classical teaching and re-evaluated in patient management.

Child and adolescent psychiatrists' attitudes and practices prescribing second generation antipsychotics.

OBJECTIVE: The purpose of this study was to examine psychiatrists' attitudes and practices in prescribing second-generation antipsychotics (SGA) to children and adolescents (referred to here as "children") and identify factors associated with off-label SGA use. METHODS: A survey was mailed to a national, randomly selected sample of 1600 child and adolescent psychiatrists identified by the American Medical Association. Multivariable logistic regression was used to identify factors, including psychiatrists' characteristics, practice characteristics, and psychiatrists' attitudes, that are associated with off-label SGA use (i.e., SGAs used in children with attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder, conduct disorder, or nonbipolar mood disorders). RESULTS: The final sample included 340 psychiatrists. Overall, respondents reported higher use and appropriateness of SGAs for United States Food and Drug Administration (FDA)-approved disorders, symptoms of aggression, and older child age. More than one third (36%) of respondents reported some off-label SGA use. Significant predictors of off-label use were: Practicing at inpatient/residential facilities (odds ratio [OR]=4.2, p=0.001); white/non-Hispanic race/ethnicity (OR=0.3, p<0.0001), agreeing that SGAs should be used for ADHD with aggression (OR=7.1, p<0.0001); and agreeing that SGAs should be used for severe delinquent behaviors (OR=1.9, p=0.03). CONCLUSIONS: Psychiatrists' attitudes about prescribing SGAs to children exhibiting aggressive symptoms were associated with off-label SGA use. Research is needed to understand the construct of aggression, potential interaction effects of aggression with diagnostic criteria, and their impact on SGA use.

Validation study of the Self-Assessment Goal Achievement (SAGA) questionnaire for lower urinary tract symptoms.

BACKGROUND: Patients' treatment goals for overactive bladder (OAB) and other lower urinary tract symptoms (LUTS) may not be aligned with their healthcare provider's goals. Successful management of OAB symptoms is improved by individualised treatment plans with attainable treatment goals. Goal attainment setting may facilitate patient-provider interaction and the development of a personalised treatment plan based on realistic, individual goals, thereby increasing patient satisfaction and therapeutic outcomes. The purpose of this study was to validate the utility of the Self-Assessment Goal Achievement (SAGA) questionnaire for LUTS in helping patients identify and achieve realistic treatment goals. METHODS: The 2-module SAGA questionnaire consists of nine prespecified (fixed) items and five open-ended items for goal identification and ranking (baseline module) and goal achievement rating (follow-up module). Adult patients in the United States (n = 104) seeking treatment for LUTS, including symptoms of OAB, completed the SAGA baseline module, micturition diary, other patient-reported outcome measures (PROs), and discussed their urinary goals with a clinician at baseline. The SAGA follow-up module was completed 2-4 months later. SAGA was validated based on analyses of face, concurrent, known-groups, and convergent validity and item distribution. RESULTS: Among the nine fixed goals of SAGA, four were ranked as very important by > 50% of patients (i.e. reduce night-time frequency, daytime frequency, urine leakage, urgency). Most patients did not change the importance level of their goals after discussion with their healthcare provider. Pearson correlations between SAGA, diary variables and PRO scores were generally of low to moderate strength. The global mean (SD) follow-up SAGA T-score was 32.54 (12.54), indicating that overall goal attainment was not achieved after 3 months. The goal attainment score was significantly different between groups differing in symptom severity, health-related quality of life, bladder control and continence status. CONCLUSIONS: The results support the validity of SAGA as a measure of patients' goals and goal achievement for the treatment of LUTS, including symptoms of OAB. SAGA may improve healthcare provider-patient interactions and treatment outcomes in clinical practice.

Survey of United States child and adolescent psychiatrists' cardiac screening practices prior to starting patients on stimulants.

OBJECTIVE: The purpose of this study was to determine psychiatrists' barriers, attitudes, and practices regarding cardiac screening prior to initiating stimulants in children with attention-deficit/hyperactivity disorder. BACKGROUND: Professional and federal oversight organizations recently have debated the evidence regarding sudden cardiac death (SCD) risk with stimulants, and have published guidelines recommending cardiac screening. It is not known how psychiatrists have responded. METHODS: This study was a cross-sectional survey of 1,600 randomly-selected U.S. members of the American Academy of Child and Adolescent Psychiatry. Analyses included descriptive statistics and logistic regression. RESULTS: Response rate was 40%; 96% met eligibility criteria. Barriers to identifying cardiac disorders in general included ability to perform a routine physical examination (74%) and care coordination with primary care providers (35%). Only 27% agreed that SCD risk warranted cardiac assessment. Prior to starting a patient on stimulants, 95% of psychiatrists obtained a routine history. The majority either conducted (9%), or relied on primary care providers to conduct (67%) a physical examination; 26% did not obtain a physical examination. Nineteen percent of psychiatrists ordered an electrocardiogram (ECG), of those, non-mutually exclusive reasons for ordering an ECG included standard practice procedure (62%), clinical findings (27%), medicolegal considerations (25%), and guideline adherence (24%). On multivariate modeling, psychiatrists were less likely to conduct cardiac screening themselves if in private practice (referent: academic medical center), if >50% of their patients had private insurance, or if they believed their ability to perform a physical examination to be a barrier. When modeling cardiac screening performed by any healthcare professional (e.g., psychiatrist, primary care practitioner), screening was less likely if the psychiatrist was practicing in a community mental health center (referent: academic medical center), was male, or if >50% of that psychiatrist's patients had private insurance. CONCLUSION: Findings suggest the tacit interplay between primary care and psychiatry for the assessment and management of medical risks associated with psychotropic medications should be improved, and solutions prioritized.

Cardiac screening prior to stimulant treatment of ADHD: a survey of US-based pediatricians.

OBJECTIVES: To determine pediatricians' attitudes, barriers, and practices regarding cardiac screening before initiating treatment with stimulants for attention-deficit/hyperactivity disorder. METHODS: A survey of 1600 randomly selected, practicing US pediatricians with American Academy of Pediatrics membership was conducted. Multivariate models were created for 3 screening practices: (1) performing an in-depth cardiac history and physical (H & P) examination, (2) discussing potential stimulant-related cardiac risks, and (3) ordering an electrocardiogram (ECG). RESULTS: Of 817 respondents (51%), 525 (64%) met eligibility criteria. Regarding attitudes, pediatricians agreed that both the risk for sudden cardiac death (SCD) (24%) and legal liability (30%) were sufficiently high to warrant cardiac assessment; 75% agreed that physicians were responsible for informing families about SCD risk. When identifying cardiac disorders, few (18%) recognized performing an in-depth cardiac H & P as a barrier; in contrast, 71% recognized interpreting a pediatric ECG as a barrier. When asked about cardiac screening practices before initiating stimulant treatment for a recent patient, 93% completed a routine H & P, 48% completed an in-depth cardiac H & P, and 15% ordered an ECG. Almost half (46%) reported discussing stimulant-related cardiac risks. Multivariate modeling indicated that ≥1 of these screening practices were associated with physicians' attitudes about SCD risk, legal liability, their responsibility to inform about risk, their ability to perform an in-depth cardiac H & P, and family concerns about risk. CONCLUSIONS: Variable pediatrician attitudes and cardiac screening practices reflect the limited evidence base and conflicting guidelines regarding cardiac screening. Barriers to identifying cardiac disorders influence practice.

Painful heat reveals hyperexcitability of the temporal pole in interictal and ictal migraine States.

During migraine attacks, alterations in sensation accompanying headache may manifest as allodynia and enhanced sensitivity to light, sound, and odors. Our objective was to identify physiological changes in cortical regions in migraine patients using painful heat and functional magnetic resonance imaging (fMRI) and the structural basis for such changes using diffusion tensor imaging (DTI). In 11 interictal patients, painful heat threshold + 1°C was applied unilaterally to the forehead during fMRI scanning. Significantly greater activation was identified in the medial temporal lobe in patients relative to healthy subjects, specifically in the anterior temporal pole (TP). In patients, TP showed significantly increased functional connectivity in several brain regions relative to controls, suggesting that TP hyperexcitability may contribute to functional abnormalities in migraine. In 9 healthy subjects, DTI identified white matter connectivity between TP and pulvinar nucleus, which has been related to migraine. In 8 patients, fMRI activation in TP with painful heat was exacerbated during migraine, suggesting that repeated migraines may sensitize TP. This article investigates a nonclassical role of TP in migraineurs. Observed temporal lobe abnormalities may provide a basis for many of the perceptual changes in migraineurs and may serve as a potential interictal biomarker for drug efficacy.

Human cerebellar responses to brush and heat stimuli in healthy and neuropathic pain subjects.

Though human pain imaging studies almost always demonstrate activation in the cerebellum, the role of the cerebellum in pain function is not well understood. Here we present results from two studies on the effects of noxious thermal heat and brush applied to the right side of the face in a group of healthy subjects (Group I) and a group of patients with neuropathic pain (Group II) who are more sensitive to both thermal and mechanical stimuli. Statistically significant activations and volumes of activations were defined in the cerebellum. Activated cerebellar structures were identified by colocalization of fMRI activation with the 'MRI Atlas of the Human Cerebellum'. Functional data (obtained using a 3T magnet) were defined in terms of maximum voxels and volume of activation in the cerebellum. Volume maps were then mapped onto two millimeter serial slices taken through the cerebellum in order to identify activation within regions defined by the activation volume. The data indicate that different regions of the cerebellum are involved in acute and chronic pain processing. Heat produces greater contralateral activation compared with brush, while brush resulted in more ipsilateral/bilateral cerebellar activation. Further, innocuous brush stimuli in healthy subjects produced decreased cerebellar activation in lobules concerned with somatosensory processing. The data also suggest a dichotomy of innocuous stimuli/sensorimotor cerebellum activation versus noxious experience/cognitive/limbic cerebellum activation. These results lead us to propose that the cerebellum may modulate the emotional and cognitive experience that distinguishes the perception of pain from the appreciation of innocuous sensory stimulation.

Photo amidoglycosylation of an allal azidoformate. Synthesis of beta-2-amido allopyranosides.

[figure: see text] Photolysis of an allal C-3 azidoformate provoked intramolecular nitrene insertion into the glycal C=C unit and allowed direct incorporation of alcohol nucleophiles as beta-disposed substituents at C-1. The 2-amido allopyranoside products were elaborated via N-acylation and selective oxazolidinone hydrolysis, providing N-Boc-protected 2-amino sugars and simplifying stereochemical assignments. Synthesis of the potentially labile allal azidoformate was achieved via reaction of the corresponding carbonyl imidazolide with trimethylsilyl azide, facilitated by dibutyltin oxide.

American Academy of Pediatrics. Committee on Injury and Poison Prevention. Safe transportation of newborns at hospital discharge.

All hospitals should set policies that require the discharge of every newborn in a car safety seat that is appropriate for the infant's maturity and medical condition. Discharge policies for newborns should include a parent education component, regular review of educational materials, and periodic in-service education for responsible staff. Appropriate child restraint systems should become a benefit of coverage by Medicaid, managed care organizations, and other third-party insurers.

American Academy of Pediatrics. Committee on Injury and Poison Prevention. Transporting children with special health care needs.

Children with special health care needs should have access to proper resources for safe transportation. This statement reviews important considerations for transporting children with special health care needs and provides current guidelines for the protection of children with specific health care needs, including those with a tracheostomy, a spica cast, challenging behaviors, or muscle tone abnormalities as well as those transported in wheelchairs.

The hospital record of the injured child and the need for external cause-of-injury codes. American Academy of Pediatrics. Committee on Injury and Poison Prevention, 1998-1999.

Proper record-keeping of emergency department visits and hospitalizations of injured children is vital for appropriate patient management. Determination and documentation of the circumstances surrounding the injury event are essential. This information not only is the basis for preventive counseling, but also provides clues about how similar injuries in other youth can be avoided. The hospital records have an important secondary purpose; namely, if sufficient information about the cause and mechanism of injury is documented, it can be subsequently coded, electronically compiled, and retrieved later to provide an epidemiologic profile of the injury, the first step in prevention at the population level. To be of greatest use, hospital records should indicate the "who, what, when, where, why, and how" of the injury occurrence and whether protective equipment (eg, a seat belt) was used. The pediatrician has two important roles in this area: to document fully the injury event and to advocate the use of standardized external cause-of-injury codes, which allow such data to be compiled and analyzed.

Abnormal tympanography after supine bottle feeding.

OBJECTIVE: To determine whether bottle feeding with the infant in the supine position is related to entry of milk into the middle ear, thereby predisposing the infant to otitis media. STUDY DESIGN: Ninety children, aged 7 to 24 months, who were free of respiratory infection and had normal tympanograms initially, were bottle fed in either the supine or the semiupright position, and tympanography was repeated immediately afterward. RESULTS: Thirty-four (59.6%) of the 57 infants fed in the supine position had abnormal postfeeding tympanographic results compared with only five (15%) of the 33 infants fed in the semiupright position (p < 0.005). In addition, when the infants with abnormal tympanograms were placed in semiupright or prone positions for 15 minutes after feeding, the majority of tympanograms returned to normal. CONCLUSION: These data suggest that supine bottle feeding has a significant effect on middle-ear pressure dynamics, probably caused by the aspiration of milk into the ear. The results also suggest that repositioning infants after feeding may mitigate the effects of supine feeding, at least in healthy children. Although this study did not demonstrate that tympanographic abnormality definitely predisposes to otitis media, it provides more evidence to encourage the practice of feeding infants in a semiupright position.
