Weight bias among exercise and nutrition professionals: a systematic review. Obes Rev 2018; 19:1492-1503.

Abstract
Obesity affects approximately one-third of American adults. Recent evidence suggests that weight bias may be pervasive among both exercise and nutrition professionals working with adults who have obesity. However, the published literature on this topic is limited. This review aimed to (i) systematically review existing literature examining weight bias among exercise and nutrition professionals; (ii) discuss the implications of this evidence for exercise and nutrition professionals and their clients; (iii) address gaps and limitations of this literature; and (iv) identify future research directions. Of the 31 studies that met the criteria for this review, 20 examined weight bias among exercise professionals, of which 17 (85%) found evidence of weight bias among professionals practicing physical therapy (n = 4), physical education (n = 8) and personal/group fitness training (n = 5). Of 11 studies examining weight bias among nutrition professionals, eight (73%) found evidence of weight bias. These findings demonstrate fairly consistent evidence of weight bias among exercise and nutrition professionals. However, the majority of studies were cross-sectional (90%). Given that weight bias may compromise quality of care and potentially reinforce weight gain and associated negative health consequences in patients with obesity, it is imperative for future work to examine the causes and consequences of weight bias within exercise and nutrition professions using more rigorous study designs.

Abstract
BACKGROUND Serious mental illness (SMI) is profoundly stigmatised, such that there is even an impact on relatives of people with SMI. Aims To develop and validate a scale to comprehensively measure self-stigma among first-degree relatives of individuals with SMI. METHOD We conducted group interviews focusing on self-stigma with first-degree relatives (n = 20) of people with SMI, from which 74 representative quotations were reframed as Likert-type items. Cognitive interviews with relatives (n = 11) identified 30 items for the Self-Stigma in Relatives of people with Mental Illness (SSRMI) scale. Relatives (n = 195) completed the scale twice, a month apart, together with four external correlate scales. RESULTS The 30-item SSRMI was reliable, with scores stable over time. Its single-factor structure allowed generation of a 10-item version. Construct validity of 30- and 10-item versions was supported by expected relationships with external correlates. CONCLUSIONS Both versions of the SSRMI scale are valid and reliable instruments appropriate for use in clinical and research contexts. Declaration of interest None.

Abstract
Intracranial calcification (ICC) is a relatively common radiological finding in children undergoing investigation for neurological disorders. Many causes are recognised, and ICC is often regarded as a non-specific sign.From an ongoing study of ICC, we identified 5 patients with characteristic radiological features, in whom a mutation in the COL4A1 gene was found.All patients had CT and MR imaging. MR images demonstrated features of periventricular leukomalacia with irregular dilatation of the lateral ventricles with or without porencephaly, loss of hemispheric white matter volume, and high signal on T2 and FLAIR sequences within periventricular and deep white matter. Calcification was apparent on MR in 4 patients. CT scans demonstrated spot and linear calcification in the subependymal region and around areas of porencephaly. Calcification was also visible in the deep cerebral white matter and basal ganglia. 1 patient showed calcification in the central pons.ICC occurs in COL4A1-related disease. The radiological features are distinct from other conditions demonstrating recognisable patterns of ICC, such as congenital cytomegalovirus infection and Aicardi-Goutiéres syndrome. In the absence of a known risk factor for periventricular leukomalacia, the presence of these radio-logical findings should suggest the possibility of COL4A1-related disease.

Abstract
OBJECTIVES To examine cardiac structural and functional changes in twin-twin transfusion syndrome (TTTS), relative to Quintero stage, as a means of evaluating the spectrum of cardiomyopathy in TTTS. METHODS This was a cross-sectional, retrospective study of 42 consecutive cases of TTTS referred to a single fetal therapy center. Quintero stages were assigned by standard criteria. Presence of ventricular hypertrophy, cardiomegaly, atrioventricular valve regurgitation (AVVR), ventricular systolic dysfunction and right ventricular outflow tract obstruction on fetal echocardiography were noted. The Doppler myocardial performance index (MPI), an index of global ventricular function, was calculated for both ventricles in subjects with adequate Doppler data. We compared cardiac changes across Quintero stages. RESULTS There was no cardiomyopathy observed in donor twins. The majority of subjects presented at Quintero Stage I (n = 14), II (n = 14) or III (n = 11), with fewer at Stages IV (n = 2) or V (n = 1). As early as Quintero Stages I and II, a significant proportion of recipient twins had ventricular hypertrophy (17/28, 61%), AVVR (6/28, 21%) or quantitative abnormalities in either right (12/24, 50%) or left (14/24, 58%) ventricular function. Increasing prevalence of biventricular systolic dysfunction and cardiomegaly accompanied advancing Quintero stage. CONCLUSIONS Changes in cardiac structure and function not reflected in Quintero staging occur in recipient twins early in the evolution of TTTS. Incorporation of cardiac findings into assessment of TTTS severity may prove useful in stratification of risk and treatment selection.

Abstract
We describe 15 members of a Caucasian family with an apparently homoplasmic T-->C mutation at nucleotide position 9185 (9185T>C) in the mtDNA encoded MTATP6 (ATPase 6) gene. The clinical phenotype is extremely variable and includes late-onset Leigh syndrome (LS), isolated demyelinating peripheral neuropathy and neurogenic muscle weakness, ataxia and retinitis pigmentosa (NARP). Following recent reports of this same mutation in a single case and in a family with late-onset LS and NARP-like features, our paper emphasises the role of MTATP6 in LS and expands the associated clinical phenotype further.

Abstract
AIM To determine incidence, aetiology, and clinical features of subdural haematoma and effusion (SDH/E) in infancy throughout the British Isles. METHODS Cases were notified to the British Paediatric Surveillance Unit over 12 months by paediatricians, neurosurgeons, and paediatric and forensic pathologists. RESULTS A total of 186 infants (121 boys, 65 girls) aged 0-2 years were identified. Annual incidence of SDH/E for the UK and Republic of Ireland is 12.54/100,000 aged 0-2 (95% CI 10.3 to 14.62) and 24.1/100,000 aged 0-1 (95% CI 20.89 to 28.18). A total of 106 infants suffered non-accidental head injury (NAHI), 7 accidental head injury, 26 a perinatal cause, 7 a non-traumatic medical condition, 23 meningitis, and in 17 the cause was undetermined; 35 infants died. Significant differences were found in injury pattern, body weight, and Townsend score between NAHI and SDH/E from other cause. There were fewer diagnostic investigations in non-NAHI cases. Delay in diagnosis of greater than a week occurred in 48/181. CONCLUSION SDH/E is a significant cause of morbidity and mortality in infancy. NAHI is the predominant cause of SDH/E. SDH/E can present in a non-specific and varied way and must be considered in any infant who is unwell. Determining the cause of the SDH/E in some cases continues to present a diagnostic challenge.

Abstract
Omeprazole is a unique and effective agent for suppression of gastric acid secretion. It promises to be especially useful in Zollinger-Ellison Syndrome (1) and in other patients who have failed to respond to H2 antagonist therapy. The dose requirement for zollinger-ellison syndrome (ZES) disease is upto 180 mg per day. The drug omeprazole shows biological half life of 2-3 hours. (2) Considering its proven therapeutic efficacy for ZES disease, this study is attempted to formulate sustained release capsule containing enteric coated granules. For formulating sustained release drug delivery system immediate release dose (IR) is calculated as 10 mg of drug and sustained release dose (SR) is taken as 50 mg. (3) The polymers used for retarding the release are Ethyl Cellulose (EC) and Hydroxy Propyl Methyl Cellulose (HPMC). Solvent evaporation technique is followed to prepare sustained release granules. Granules are finally coated with enteric coating of Suteric (Polyvinly acetate phthalate, PVAP). Thus the eight capsule formulations are prepared and formulation found very close to theoretical sustained release (TSR) according to in vitro study (4) is subjected to stability studies. Results show that product should be stored at room temperature or below ambient temperature.

Abstract
A systematic literature review from 1966 to 2000 revealed 2,730 English-language publications on the role of bacteria in human primary dental caries in vivo. The most pertinent 313 papers were analyzed in evidence tables accessible online (http://www.nidcr.nih.gov). The search targeted all bacterial types implicated previously in caries and asked two questions. First, what is the association of specific bacteria with tooth decay and can causation be attributed to any of those bacteria? Retrieved studies were categorized as randomized-blinded-interventional, longitudinal, case-control, and cross-sectional and were weighted in descending order in terms of significance. Although many studies, due to ethical requirements, had confounding variables, they still indicate strongly: 1) the central role of the mutans streptococci in initiation of caries of smooth surfaces and fissures of crowns of teeth and suggests their potent role in induction of root surface caries; and 2) that lactobacilli are implicated as important contributory bacteria in tooth decay, but their role in induction of lesions is not well supported. Second, what is the source of infection by cariogenic bacteria? Molecular/genetic studies of implicated bacteria isolated from humans, randomized-blinded-interventional, and longitudinal studies indicate that mutans streptococci are spread vertically among humans, mostly from mothers to their children. Implications of these conclusions are briefly discussed. The most significant problems of literature interpretation include the benefits/shortcomings of salivary and plaque monitoring of the flora, the role of sugar(s) in decay as it influences the flora, and modeling strategies to predict lesion score increments as distinct from determination of the etiological role of specific bacteria. Future directions for microbiological clinical caries research are suggested, and the use of the term "caries" to describe the disease, not its lesions, is urged.

Abstract
In the diabetic population, wound and foot infections are often mixed, containing from three to six organisms. This creates a significant problem regarding antibiotic protocols. Many of these episodes result in contiguous bone infections with subsequent erosive changes, sequestra, and involucrum. A multidisciplinary approach to treatment is often required. Studies have shown that a protocol of 6 weeks of intravenous antibiotics may be appropriate to treat osteomyelitis; however, this is controversial and often not curative. Osteomyelitis is a surgical disease; a subtle balance between medical and surgical therapy is necessary if a potentially curative outcome is to be achieved. The duration of antibiotic therapy may be shortened considerably after surgical intervention. In cases of infection mitigated by severe peripheral vascular disease, end-stage renal disease, diabetes, or other medical problems where surgery is not an option, long-term antibiotics may be used as suppressive therapy along with adjunctive local treatments. The following is the second article of a two-part series. The first paper discussed the diagnosis and microbiology of contiguous osteomyelitis in the diabetic foot. This article outlines the various medical, antibiotic, and surgical options available to the clinician. Adjunctive and alternative therapies also are discussed.

Abstract
Neurological integrity in sick children is difficult to assess clinically. The aim of this study was to determine the predictive value of EEG activity recorded with a bedside EEG analysing monitor in an intensive care unit. EEG activity was monitored in 108 children (age range 2 weeks to 16 years, median 1.7 years) considered at risk for cerebral abnormalities with a cerebral function analysing monitor (CFAM). Recordings were evaluated for features of background EEG activity including mean amplitude, frequencies, and symmetry. Electrical seizure activity was quantified if present. Predictive value of the EEG features was evaluated relative to the clinical neurological outcome after one year. Asymmetrical recordings were not seen in any child with a normal outcome. Suppression of background activity was seen in 75% of the children who died. Seizures were present in 68% of children with a poor outcome. Seventeen of the 32 children (65%) who died had prolonged seizures. Absence of seizures and the presence of superimposed fast EEG activity in response to benzodiazepine infusions correlated with good outcome. A combination of two or more predictive EEG features demonstrated >90% specificity and positive predictive likelihood of poor outcome. EEG features provide information about the functional cerebral integrity of sick children. Changes in cerebral activity detected by the CFAM aid decision making by providing such information readily at the bedside in intensive care.

Abstract
We screened automated ambulatory medical records, hospital and emergency room claims, and pharmacy records of 2,826 health maintenance organization (HMO) members who gave birth over a 30-month period. Full-text ambulatory records were reviewed for the 30-day postpartum period to confirm infection status for a weighted sample of cases. The overall postpartum infection rate was 6.0%, with rates of 7.4% following cesarean section and 5.5% following vaginal delivery. Rehospitalization; cesarean delivery; antistaphylococcal antibiotics; diagnosis codes for mastitis, endometritis, and wound infection; and ambulatory blood or wound cultures were important predictors of infection. Use of automated information routinely collected by HMOs and insurers allows efficient identification of postpartum infections not detected by conventional surveillance.

Abstract
Approximately 914 new dog bite injuries requiring emergency department visits occur daily in the United States. Attacks by dogs with training and strength to attack should be triaged cautiously because of the possibility of serious internal injury. A high index of suspicion is needed when treating patients with neck injuries secondary to dog bites. We report a case of successfully treated combined carotid artery and laryngeal injury produced by a dog bite.

Abstract
BACKGROUND Females have worse outcome than do males after coronary artery bypass grafting; however, gender effects on length of stay (LOS) outcomes, such as duration of intubation or intensive care unit (ICU) LOS, have not been evaluated previously. The authors hypothesized that adjustment for pertinent preoperative covariates would eliminate any significant effect of gender on duration of intubation, LOS in the ICU after extubation, total ICU LOS, postoperative (exclusive of ICU) LOS, or total postoperative LOS. METHODS Patients undergoing elective or urgent primary coronary artery bypass grafting surgery at 51 academic health centers in 1995 and 1997 were studied. Unique multivariable statistical models were developed for duration of intubation, ICU LOS after extubation, total ICU LOS, and postoperative (exclusive of ICU and total) LOS to test for independent associations with gender. Preoperative but not intraoperative or postoperative variables were included in the model. P> or =0.01 was considered significant. RESULTS All LOSs were of significantly longer duration in females than in males in both the 1995 (n = 1,064) and 1997 (n = 910) data collections. After covariate adjustment, female sex remained associated with significantly longer duration ICU LOS and total postoperative LOS in both the 1995 (female:male ratios 1.30:1 and 1.13:1, respectively) and the 1997 (female:male ratios 1.19:1 and 1.12:1, respectively) data sets. After covariate adjustment, duration of intubation and ICU LOS after extubation were of significantly longer duration in women than men in 1995 (female:male ratios 1.22:1 and 1.39:1, respectively), but the differences were not significant in 1997. CONCLUSIONS Even in the context of accelerated recovery programs, these analyses show that female sex has powerful associations with increased LOS intervals for coronary artery bypass grafting surgery, even after adjustment for preoperative covariates. These effects could result from differences in the ways in which men and women respond to coronary artery disease, anesthesia, and coronary artery bypass grafting surgery, or to bias on the part of healthcare workers.

Abstract
Although most surgical site infections (SSIs) occur after hospital discharge, there is no efficient way to identify them. The utility of automated claims and electronic medical record data for this purpose was assessed in a cohort of 4086 nonobstetric procedures following which 96 postdischarge SSIs occurred. Coded diagnoses, tests, and treatments were assessed by use of recursive partitioning, with 10-fold cross-validation, and logistic regression with bootstrap resampling. Specific codes and combinations of codes identified a subset of 2% of all procedures among which 74% of SSIs had occurred. Accepting a specificity of 92% improved the sensitivity from 74% to 92%. Use of only hospital discharge diagnosis codes plus pharmacy dispensing data had sensitivity of 77% and specificity of 94%. All of these performance characteristics were better than questionnaire responses from patients or surgeons. Thus, information routinely collected by health care systems can be the basis of an efficient, largely passive, surveillance system for postdischarge SSIs.

Abstract
BACKGROUND The authors hypothesized that shorter-acting opioid and neuromuscular blocking drugs would be associated with reductions in duration of intubation, length of stay (LOS) in the intensive care unit (ICU) after tracheal extubation, or postoperative (exclusive of ICU) LOS, and that shorter durations of intubation would be associated with reduced ICU LOS after extubation and postoperative (exclusive of ICU) LOS. METHODS One-thousand ninety-four patients undergoing primary coronary artery bypass graft surgery at 40 academic health centers were studied. Multiple patient-related factors were included in multivariate models for hypothesis testing. RESULTS The duration of tracheal intubation, ICU LOS after extubation, and postoperative (exclusive of ICU) LOS all varied significantly by site. There was no difference between vecuronium and pancuronium in duration of intubation, ICU LOS after extubation, or postoperative (exclusive of ICU) LOS. Use of sufentanil rather than fentanyl was associated with a significant (P=0.045) reduction of 1.9 h (95% CI, 0.04 to 4.1 h) in duration of tracheal intubation but had no significant effect on ICU LOS after extubation, total ICU LOS, postoperative (exclusive of ICU) LOS, or total postoperative LOS. The authors' best model predicts a complex association between increasing duration of intubation and both ICU LOS after tracheal extubation and postoperative (exclusive of ICU) LOS, which was associated with an increase in those measures when duration of intubation exceeded 7.3 or 3 h, respectively. CONCLUSIONS The LOS measures varied considerably among the institutions. Use of shorter-acting opioid and neuromuscular blocking drugs had no association with ICU LOS after tracheal extubation or with postoperative (exclusive of ICU) LOS. Only when the duration of intubation exceeded threshold values was it associated with increased LOS measures.

Abstract
Vincristine is an anti-neoplastic agent for intravenous use. Inadvertent intrathecal administration of vincristine tends to follow a predictable clinical sequence of a progressive ascending radiculomyeloencephalopathy, usually fatal in outcome. We report a case of a 10-year-old girl who suffered an inadvertent intrathecal vincristine administration. We have outlined the management strategy used and her consequent neurological progress. She has survived but with a significant neurological deficit. Her outcome is, however, less severe than in previous literature reports; this may in part be attributable to early aggressive neurological management. This case also serves to highlight the tragic consequences of human error when handling chemotherapeutic agents of this nature.

Abstract
Clinical benchmarking is a tool of CQI that can be used to improve outcomes in areas of strategic importance. While it is a simple tool, benchmarking requires a long-term commitment from the entire organization involved in its use to be successful. Benchmarking is a means of setting goals or targets. As a tool used for continuous quality management, benchmarking is an ongoing activity of comparing an organization's service, product, or process with similar ones outside the organization that are known to be the best. In attempting to emulate or surpass "best practice," an organization must set challenging but attainable goals and reach them with a plan of realistic and efficient actions.

Abstract
Consumer choice is a central principle of psychosocial rehabilitation and supported housing approaches. This study assessed level of housing choice and the relationship of choice to community success in supported housing demonstration projects in five states. Assessment of level of choice about housing revealed very limited housing options and a high degree of influence from service providers over housing choice. Despite few options, most respondents liked their housing option(s) and felt they had enough information to make a good housing decision. The relationship of choice to community success over time demonstrated that choice was positively related to housing satisfaction, residential stability, and psychological well-being. Discussion focuses on implications of the findings for mental health services and public policy.

Abstract
Seizures in a term infant with Ohtahara syndrome, associated with polymicrogyria, and a pre-term neonate with similar clinical features, failed to respond to conventional anticonvulsants, but were controlled with vigabatrin monotherapy. Another infant with Aicardi syndrome improved with vigabatrin. Autopsy in the first infant showed no evidence of intramyelinic oedema. The developmental outcome in the two survivors was better than expected for their condition.

Abstract
The clinical arm of the University of Utah operates a 400 bed general hospital and 30 specialty and subspecialty clinics and with the advent of managed care will soon be linked to a much wider network of health care facilities throughout the state. Each of these patient care facilities maintains its own patient record. To provide common access to data on any patient needed to provide continuity to the care process where ever it occurs, the institution has embarked on the development of a completely electronic patient record. In this paper we will describe the route we have taken to achieve this goal in hopes of providing some sign posts along the way for others seeking the same destination.

Abstract
Assessment of brain function is important in predicting long term outcome in sick neonates thus stimulating increasing interest in methods of cerebral surveillance. A report using the Cerebro Trac 2500 in adult intensive care suggested this monitor may provide more information about ongoing cerebral activity than the Cerebral Function Monitor (CFM). Simultaneous recordings in a cross-section of the neonatal population were obtained with multichannel EEG monitor, CFM and Cerebro Trac. Both conventional EEG and CFM determined changes in sleep states and background activity. Seizures of greater than 30 seconds duration were detected by both analyzing monitors, although shorter duration transients were not apparent. Despite the apparent similarity in fixed filters in both CFM and Cerebro Trac, the Cerebro Trac seemed to filter out the lower frequencies that can predominate in the neonatal EEG. The Cerebro Trac did not confer any advantage over the CFM for neonatal cerebral surveillance.

Abstract
On 19 January 1992, heterogeneous loss of HNO(3), ClNO(3), and HCl was observed in part of the Mount Pinatubo volcanic cloud that had cooled as a result of forced ascent. Portions of the volcanic cloud froze near 191 kelvin. The reaction probability of ClNO(3) and the solubility of HNO(3) were close to laboratory measurements on liquid sulfuric acid. The magnitude of the observed loss of HCl suggests that it underwent a heterogeneous reaction. Such reactions could lead to substantial loss of HCl on background sulfuric acid particles and so be important for polar ozone loss.

Abstract
Two N-linked sites of glycosylation in the insulin receptor were examined for their contribution to insulin binding, tyrosine kinase activity, and receptor biosynthesis. Asn397 and Asn418 were replaced by Gln using site-directed mutagenesis either as single mutations, i.e., Q-397 and Q-418, or as a double mutation in which both sites were removed (Q-D). The mutations were transiently expressed in COS cells and the findings compared with cells that transiently expressed the wild-type human insulin receptor. Q-397 and Q-418 mutant insulin receptors had insulin-binding characteristics similar to the wild-type human insulin receptor, whereas no insulin-binding activity could be detected above the control level in cells transfected with Q-D. Flow cytometry with antibodies against the human insulin receptor indicated the presence of Q-397, Q-418, and wild-type human insulin receptors in the surface of COS cells and failed to demonstrate a Q-D receptor. Insulin-induced autophosphorylation was similar in Q-397, Q-418, and wild-type human insulin receptors as was their ability to phosphorylate an artificial substrate, poly Glu-Tyr (4:1). Our inability to detect Q-D receptors was not caused by a lack of Q-D mRNA. COS cells transfected with Q-D cDNA generated as much Q-D mRNA as the amount of wild-type human insulin receptor mRNA present in cells transfected with wild-type receptor cDNA. Finally, pulse-chase experiments with [35S]Met were able to detect 190,000-M(r) proreceptors and the alpha-subunits for Q-397, Q-418, and wild-type human insulin receptors.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Menkes disease is an X-linked recessive disorder of copper metabolism resulting in death in early infancy. The gene has been mapped to band Xq13 based, in part, on a translocation breakpoint in a female with the disease, which was found to lie within 300 kilobases (kb) of the PGK-1 locus, allowing the isolation of a YAC clone spanning the breakpoint. Phage subclones from the breakpoint region were isolated and used to screen cDNA libraries. cDNA clones were found which detect an 8 kb transcript from normal individuals but show diminished or absent hybridization in Menkes disease patients. Partial sequence of the cDNA shows a unique open reading frame containing putative metal binding motifs which have been found in heavy metal resistance genes in bacteria. This gene is a strong candidate for the Menkes disease gene.

Abstract
Diffuse neuronal migration disorders associated with epilepsy can now be recognized by modern neuroimaging techniques, particularly high-resolution MRI. We report 10 patients with a recently described MRI picture of continuous or generalized band heterotopia underlying the cortical mantle, giving the appearance of a "double cortex." They have epilepsy, and almost all have mental retardation. The epileptic disorder varies in nature and degree of severity. Patients may present with infantile spasms, a Lennox-Gastaut syndrome, or other forms of secondary generalized or multifocal epilepsy. Response to medical treatment is variable. Callosotomy may lead to considerable reduction of drop attacks, present in 60%. Mental retardation is usually mild or moderate, and only rarely severe. It correlates with the type of epileptic syndrome, and is greater in patients with more disorganized cortex overlying the heterotopia. Recognition of this entity by MRI is important for appropriate diagnosis of the epileptic disorder, planning of therapeutic strategy, and prognosis.

Abstract
Full HLA-A,B and DR typing was carried out on 92 women with proteinuric pre-eclampsia, 80 of their husbands and 46 of their babies. The results were compared with corresponding data from 65 normotensive pregnancies involving primiparous women. The frequency of HLA-DR4 was increased in the pre-eclamptic women (RR 3.1; p less than 0.005) and in the babies of pre-eclamptic pregnancies (RR 2.6; p less than 0.03). The strongest association, however, was with sharing of HLA-DR4 between mother and fetus (RR 4.2; p = 0.01). There was no increase in HLA antigen sharing in general between spouses or maternal-fetal pairs in pre-eclampsia. Nor did pre-eclamptic women exhibit increased homozygosity in general at any HLA locus. We conclude that genetic susceptibility to pre-eclampsia depends at least partly on fetomaternal compatibility for a gene or genes associated with HLA-DR4.

Abstract
This paper describes an investigation of the comprehensive aerosol correlative measurement experiments conducted between November 1984 and July 1986 for satellite measurement program of the Stratospheric Aerosol and Gas Experiment (SAGE II). The correlative sensors involved in the experiments consist of the NASA Ames Research Center impactor/laser probe, the University of Wyoming dustsonde, and the NASA Langley Research Center airborne 14-inch (36 cm) lidar system. The approach of the analysis is to compare the primary aerosol quantities measured by the ground-based instruments with the calculated ones based on the aerosol size distributions retrieved from the SAGE II aerosol extinction measurements. The analysis shows that the aerosol size distributions derived from the SAGE II observations agree qualitatively with the in situ measurements made by the impactor/laser probe. The SAGE II-derived vertical distributions of the ratio N0.15/N0.25 (where Nr is the cumulative aerosol concentration for particle radii greater than r, in micrometers) and the aerosol backscatter profiles at 0.532- and 0.6943-micrometer lidar wavelengths are shown to agree with the dustsonde and the 14-inch (36-cm) lidar observations, with the differences being within the respective uncertainties of the SAGE II and the other instruments.
