Abstract
OBJECTIVE Little is known about factors associated with discharge against medical advice (DAMA) in adolescent acute care hospitalization for suicidal ideation (SI) and suicide attempt (SA). Our study seeks to determine whether certain socioeconomic factors or hospital characteristics are associated with DAMA in this population. METHOD This retrospective cross-sectional study used data from the National Inpatient Sample from the 2015 fourth quarter to 2019. We included children 10 to 19 years of age hospitalized with a primary or secondary International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis of SI or SA. Exposures were patient socio-demographics and hospital characteristics. The outcome was DAMA. Logistic regression generated odds ratios (ORs) with 95% CIs to measure the association between each patient and hospital characteristics and DAMA. RESULTS Of 476,755 hospitalizations meeting inclusion criteria, 3,825 (0.8%) were DAMA. After adjusting for socio-demographics and hospital characteristics, predictive factors for DAMA were age 16 to 19 years (OR = 1.41; CI = 1.08-1.82), self-pay status (OR = 1.43; CI = 1.12-1.83), hospital region South and West (OR = 1.55; CI = 1.10-2.20 and OR = 1.79; CI = 1.26-2.54, respectively), and urban non-teaching status of the hospital (OR = 1.90; CI = 1.42-2.55). Hispanic patients were less likely to be DAMA (OR = 0.66; CI = 0.51-0.85). CONCLUSION Variations in DAMA probabilities by age, insurance status, hospital teaching status, and hospital regions suggest a need for a better understanding of this uncommon outcome.

Abstract
A novel method for planning the placement of intra-oral lengthening devices using a paralleling device is described and illustrated with a case report. Simple radiographic measurements and study models are all that is required to construct a simple acrylic splint with guides, which allows accurate positioning of the distractors at surgery. The construction of ethylene vinyl acetate (EVA) baffles to prevent trauma to the labial mucosa from the intra-oral link arms is a technique that enhances patient comfort during distraction of the mandible. The case report demonstrates the application of the surgical planning technique and the use of EVA baffles for a patient with an overjet of 21.5 mm.

Abstract
OBJECTIVE This pilot study assessed force to debond (N); time, and site of bond failure of a single component self-etching primer (SEP) and adhesive system, Ideal 1 (GAC International Inc., USA) and compared it with the conventional acid etch and rinse regimen using 37% o-phosphoric acid solution and either Transbond XT (3M Unitek) or Ideal 1 adhesive. DESIGN In vitro laboratory study. SETTING Bristol Dental Hospital, UK. Sept 2003-Sept 2004. MATERIAL AND METHODS Nine groups of 20 premolars were bonded using metal orthodontic brackets using three protocols: (1) 37% o-phosphoric acid etch and Transbond XT adhesive; (2) 37% o-phosphoric acid and Ideal 1 adhesive; (3) Ideal 1 SEP and Ideal 1 adhesive. Force to debond and locus of bond failure were determined at three time intervals. RESULTS Enamel pre-treatment prior to bonding, namely SEP versus conventional etching had no significant effect on the median force to debond with the Ideal 1 adhesive. Similarly, when the enamel was conventionally etched, the adhesive type, namely Ideal 1 or Transbond XT, had no significant effect on the measured force to debond. However, there appeared to be differences in the locus of bond failure: failure predominated at the enamel/adhesive interface for the Transbond XT conventional etch group and at adhesive/bracket interface for the Ideal 1 SEP and adhesive group and the Ideal 1 adhesive conventional etch group. CONCLUSION These results suggested that the complete Ideal 1 SEP and adhesive system might be successful in vivo leading therefore to a clinical trial. However, implications for clean up time are discussed and improvements to in vitro study designs are advised.

Abstract
OBJECTIVE This study assessed the in vivo bond failure of the single component orthodontic self-etching primer system, Ideal 1 (GAC Orthodontic Products) and compared it with the conventional acid etching using a conventional 37% o-phosphoric acid, rinsing and drying regimen when bonding stainless steel orthodontic brackets to enamel. DESIGN Prospective randomized, controlled clinical trial. SETTING Orthodontic Department, Bristol Dental School. MATERIAL AND METHODS Twenty consecutive patients undergoing upper and lower fixed orthodontic treatment entered this cross-mouth control study. Diagonally opposite quadrants were randomly allocated to either the self-etching primer group or the conventional etching group. A total of 339 teeth were bonded with Ideal 1 light-cured adhesive. Bond failures and locus of bond failure were then recorded at 1, 6 and 12 months. RESULTS Significantly more bond failures occurred at each of the 3 time intervals, 1, 6 and 12 months, where the enamel was pretreated with the Ideal I self-etching primer, than when the enamel was treated with the conventional etchant, 37% o-phosphoric acid. With the latter the cumulative bond failure rates were 3.0, 5.3 and 14.8%, respectively. With the self-etching primer the cumulative failure rates were 29.4, 56.5 and 72.4%. CONCLUSION The study found that enamel pre-treatment with the Ideal 1 self-etching primer system prior to orthodontic bonding results in an unacceptably high bond failure rate when compared with conventional enamel acid etching.

Abstract
OBJECTIVE This study aimed to identify self report questionnaire measures of parent attributes and behaviors that have relevance for understanding injury risk among children 2-5 years of age, and test a new Parent Supervision Attributes Profile Questionnaire (PSAPQ) that was developed to measure aspects of protectiveness and parent supervision. METHODS Naturalistic observations were conducted of parents' supervision of children on playgrounds, with questionnaires subsequently completed by the parent to measure parent education, family income, parent personality attributes, attributes relevant to parent supervision, and beliefs about parents' control over the child's health status. These measures were then related to children's risk taking and injury history. RESULTS Visual supervision, auditory supervision, and physical proximity were highly intercorrelated, indicating that parents employed all types of behaviors in service of supervision, rather than relying predominantly on one type of supervisory behavior. Physical proximity was the only aspect of supervision behavior that served a protective function and related to children's risk taking behaviors: parents who remained close to their children had children who engaged in less risk taking. On questionnaires, parents who reported more conscientiousness, protectiveness, worry about safety, vigilance in supervision, confidence in their ability to keep their child safe, and belief in control over their child's health had children who showed less risk taking and/or experienced fewer injuries. The new PSAPQ measure was associated with specific aspects of supervision as well as children's risk taking and injury history. CONCLUSIONS This study reveals several parent attributes and behaviors with relevance for child injury risk that can be measured via self report questionnaires, including the new PSAPQ.

Abstract
BACKGROUND Many patients with persistent asthma need both long-acting bronchodilators and inhaled corticosteroids for optimal asthma control. OBJECTIVE Our purpose was to compare the efficacy and safety of salmeterol 50 microg combined with fluticasone 100 microg (in a combination dry powder product) with that of placebo, fluticasone, or salmeterol alone. METHODS A 12-week randomized, double-blind, multicenter study was conducted in 356 patients aged 12 years or older with asthma. After a 14-day screening period, patients were randomized to treatment with salmeterol 50 microg combined with fluticasone 100 microg (combination product), salmeterol 50 microg, fluticasone 100 microg, or placebo administered in the Diskus dry powder inhaler (GlaxoWellcome, UK) twice daily. RESULTS Mean change in FEV(1) at end point was significantly (P < or =.003) greater with the combination product (0.51 L) compared with placebo (0.01 L), salmeterol (0.11 L), and fluticasone (0.28 L). The combination product significantly increased (P < or =.013) area under the curve compared with placebo and fluticasone on day 1 and compared with placebo, salmeterol, and fluticasone at week 1 and week 12. Patients in the combination product group were less likely to withdraw from the study because of worsening asthma compared with those in the other groups (P < or =.020). The combination product significantly increased (P < or =.012) morning PEF (combination, 52.5 L/min; placebo, -23.7 L/min; salmeterol, -1.7 L/min; fluticasone, 17.3 L/min) and evening PEF at end point compared with the other groups. The combination product significantly (P < or =.025) reduced symptom scores and albuterol use compared with the other treatments and increased the percentage of nights with no awakenings and the percentage of days with no symptoms compared with placebo and salmeterol. All treatments were equally well tolerated. CONCLUSION Salmeterol 50 microg and fluticasone 100 microg combined in the Diskus powder delivery device offers significant clinical advantages over salmeterol or fluticasone alone at the same doses.

Abstract
Three hundred forty-nine patients with asthma previously treated with medium doses of inhaled corticosteroids during a 2-wk, single-blind, run-in period were randomized to treatment with salmeterol 50 microg combined with fluticasone propionate (FP) 250 microg, salmeterol 50 microg, FP 250 microg, or placebo, each given twice daily through a Diskus device for 12 wk. Mean change in FEV(1) at endpoint was significantly (p </= 0.001) greater with the salmeterol/FP combination product (0.48 L) than with placebo (-0.11 L), salmeterol (0.05 L), or FP (0.25 L). The combination product significantly increased the area under the 12-h serial FEV(1) curve relative to baseline over that with placebo, salmeterol, or FP at Day 1, Week 1, and Week 12 (p </= 0.025). Patients in the combination-product group had a significantly greater probability of remaining in the study without being withdrawn because of worsening asthma than did patients in the placebo, salmeterol, or FP groups (p </= 0.002). The combination product significantly increased (p < 0. 001) morning PEF at endpoint (53.5 L/min) as compared with placebo (-14 L/min), salmeterol (-11.6 L/min), or FP (15.2 L/min). The combination product significantly (p </= 0.011) reduced asthma symptom scores and supplemental albuterol use, and significantly increased the percentage of nights with no awakenings as compared with placebo, salmeterol, and FP (p </= 0.016). Combination treatment with salmeterol 50 microg and FP 250 microg given twice daily from the Diskus device provided better asthma control and greater improvement in pulmonary function than did the individual agents, and may simplify the management of asthma in patients who need both classes of drugs for optimal control of their disease.

Abstract
Two studies employed a known-groups validation strategy to evaluate a Thematic Apperception Test (TAT) scoring system purported to measure personal problem-solving skills, the Personal Problem-Solving System (PPSS). In Study 1 clinicians rated the records of 46 mental health outpatients for the presence of personal problem-solving skills deficits. Verbatim TAT transcripts from these patients were blindly scored using the PPSS. Participants predicted to demonstrate problem-solving deficits obtained lower PPSS scores. In Study 2 a psychiatric sample (n = 47) and a community-based comparison group (n = 47) completed a life history questionnaire, a checklist of problems currently experienced, a measure of psychiatric symptoms, and responded to 3 TAT cards. TAT responses were again blindly scored using the PPSS. In contrast to the comparison group, psychiatric patients checked a greater number of current problems, endorsed more psychiatric symptoms, and obtained lower scores on the PPSS. A discriminant function analysis using PPSS scores correctly classified 72% of these participants. PPSS scores predicted group membership even after controlling for differences in age, education, the number of problems experienced, and psychiatric symptoms. This combination of variables correctly classified 92% of the participants. Results of both studies are interpreted as supporting the discriminant validity of the PPSS.

Abstract
BACKGROUND Ondansetron hydrochloride is a selective serotonin subtype 3 (5HT3) receptor antagonist that has been shown to be an effective antiemetic in patients receiving cisplatin chemotherapy. METHODS This double-blind study compared the safety and efficacy of intravenous ondansetron with metoclopramide in patients receiving a 4- or 5-day regimen of cisplatin (20-40 mg/m2/day) combination chemotherapy. Forty-five patients were enrolled, and efficacy of the drug therapy could be studied for all 45. Patients were randomly assigned (1:1) to receive three daily intravenous doses of either 0.15 mg/kg ondansetron or 1 mg/kg metoclopramide. All patients were monitored daily for the number of emetic episodes (vomiting or retching), severity of nausea, adverse events, and laboratory safety parameters. RESULTS Seven (30%) patients who received ondansetron had no emetic episodes throughout the entire study period compared with two (9%) who received metoclopramide (P = 0.077). The greatest difference in antiemetic efficacy was seen on day 1, when 18 (78%) patients who received ondansetron had no emetic episodes compared with 3 (14%) patients who received metoclopramide (P < 0.001). Significantly fewer antiemetic treatment failures (more than five emetic episodes or withdrawal from the study) occurred with patients given ondansetron (9%) than with those given metoclopramide (50%) during the entire study period (P = 0.002). The most commonly reported adverse event associated with ondansetron therapy was headache (controlled with acetaminophen), whereas diarrhea and restlessness were the most commonly reported adverse events associated with metoclopramide therapy. Extrapyramidal symptoms were judged to have occurred in 13 patients who received metoclopramide and 1 patient who received ondansetron. However, the patient who received ondansetron subsequently was judged to have had an anxiety attack. In patients with low or normal baseline transaminase values, a greater percentage who received ondansetron had transient increases as great as twice the upper limit of normal in aspartate transaminase (5% versus 0%) and alanine transaminase (17% versus 6%) than those who received metoclopramide. CONCLUSIONS Ondansetron is superior to metoclopramide as antiemetic therapy for multiple-day cisplatin-based chemotherapy.

Abstract
The ability of cholesterol to move between bovine rod outer segment disk membranes and phospholipid membranes was examined. Disk membranes were incubated with small unilamellar phospholipid vesicles containing varying amounts of cholesterol. Aliquots were removed at specific times, and then the disks and the vesicles were separated by centrifugation and assayed for phospholipid and cholesterol content. When incubated with vesicles containing no cholesterol, the cholesterol to phospholipid ratio in the disk membrane was reduced due to migration of cholesterol from the disks into the vesicles. The cholesterol content of these cholesterol depleted disks could be readily returned to the normal disk cholesterol content by incubation of the cholesterol-depleted disks with small unilamellar vesicles containing high cholesterol. An apparent partition coefficient K was calculated as the quotient of the cholesterol/phospholipid mole ratio in the donor membranes and the cholesterol/phospholipid mole ratio in the acceptor membranes. The value of K was approximately 1 at cholesterol levels below normal disk cholesterol content, for disk membranes and phosphatidylcholine small unilamellar vesicles. Inclusion of phosphatidylethanolamine in the small unilamellar vesicle acceptor raised K, indicating that phosphatidylethanolamine creates an unfavourable environment for cholesterol. The cholesterol to phospholipid ratio of native disks could be increased by incubation with phosphatidylcholine small unilamellar vesicles (donor) which contained higher amounts of cholesterol than the disk membrane acceptor. In these experiments the distribution of cholesterol between disks and small unilamellar vesicles always favored the vesicles. The apparent partition coefficient was 1.7 at several cholesterol levels above the native disk cholesterol content. Liposomes made from lipid extracted from the disk membrane behaved in the same manner as intact disks with respect to cholesterol distribution at equilibrium. The phospholipid content of the disk membrane may be an important factor in determining the cholesterol content of the disk membrane.
