- Abstract
Objective: Despite numerous clinical trials, it is unknown whether ethnicity affects treatment response to cognitive enhancers in Alzheimer's disease (AD). There is convincing evidence of ethnic and genetic variability in drug metabolism. This article reviews the available data on ethnicity in clinical trials for AD to answer two questions: (1) what are the challenges to diagnose and treat AD across different ethnic groups, and (2) are there differences in response to pharmacologic interventions for AD across these different ethnic groups?Method: Available data from Alzheimer's Disease Cooperative Study (ADCS) randomized controlled clinical trials and from randomized controlled industry-sponsored trials for four cognitive enhancers (donepezil, galantamine, rivastigmine and sabeluzole) were pooled to assess the numbers of non-Caucasian participants.Results: The participation of ethnic minority subjects in clinical trials for AD was dependent on the funding source, although Caucasian participants were over-represented and non-Caucasian participants were under-represented in the clinical trials. Because of the low participation rate of ethnic minorities, there were insufficient data to assess any differences in treatment outcome among different ethnic groups. Strategies to improve diversity in clinical trials are discussed.Conclusion: Greater participation of ethnically diverse participants in clinical trials for AD would generate additional information on possible differences in metabolism, treatment response, adverse events to therapeutic agents, and could foster the investigation of genetic variability among ethnic groups.

INTERVIEWING in psychiatry ,CHILD psychopathology - Abstract
Previous studies have suggested that discrepant reporting in a test-retest reliability paradigm is not purely random measurement error, but partly a function of a systematic tendency to say "no" during retest to questions answered positively at initial testing ("attenuation"). To examine features of interview questions that may be associated with attenuation, three raters independently assessed the structural and content features of questions from the Diagnostic Interview Schedule for Children (version 2.3) and linked these to data from a test-retest reliability study of 223 community respondents (parent and child reports). Results indicated that for both parent and youth reports, item features most strongly associated with attenuation were (a) being a "stem" question (asked of all respondents, regardless of any skip structure); (b) question placement in the first half of the interview; (c) question length; (d) question complexity; or (e) requiring assessment of the timing, duration, or frequency of a symptom. Findings may be explained by participants' conscious efforts to avoid further questions or by their learning more about the nature and purpose of the interview as they gain more experience; alternatively, findings may represent a methodological artifact of structured interview design.

CONDUCT disorders in adolescence ,BEHAVIOR disorders in children - Abstract
In a cross-sectional household sample of 9-through 17-year-old youths from 4 U.S. communities, youths with earlier ages of onset of conduct problems engaged in more conduct problems than youths with later ages of onset when current age and gender were controlled. Specifically, youths with earlier ages of onset were more likely to engage in several types of physical aggression, frequent lying, theft, and vandalism and were less likely to engage in only truancy. There also was an inverse relation between age of onset and level of functional impairment, mental health service use, and meeting diagnostic criteria for conduct disorder, attention-deficit hyperactivity disorder, and oppositional defiant disorder. Within the limits of cross-sectional data, these results support the hypothesis that key aspects of the heterogeneity of conduct problems among youths are related to the age of onset of conduct problems.

COMPOSITE International Diagnostic Interview ,INTERVIEWING in psychiatry ,PSYCHIATRIC diagnosis ,MENTAL illness ,PATHOLOGICAL psychology - Abstract
The CIDI is a fully standardised diagnostic interview designed for assessing mental disorders based on the definitions and criteria of ICD-10 and DSM-III-R. Field trials with the CIDI have been conducted in 18 centres around the world, to test the feasibility and reliability of the CIDI in different cultures and settings, as well as to test the inter-rater agreement for the different types of questions used. Of 590 subjects interviewed across all sites and rated by an interviewer and observer, 575 were eligible for analysis. The CIDI was judged to be acceptable for most subjects and was appropriate for use in different kinds of settings. Many subjects fulfilled criteria for more than one diagnosis (lifetime and six-month). The most frequent lifetime disorders were generalised anxiety, major depression, tobacco use disorders, and agoraphobia. Percentage agreements for all diagnoses were above 90% and the kappa values were all highly significant. No significant numbers of diagnostic disconcordances were found with lifetime, six-month, and four-week time frames. [ABSTRACT FROM AUTHOR]

- Abstract
Human neutrophils participate in the host innate immune response, partly mediated by the multicomponent superoxide-generating enzyme NADPH oxidase. A correlation between phosphorylation of cytosolic NADPH oxidase components and enzyme activation has been identified but is not well understood. We previously showed that p22(phox), the small subunit of the membrane-bound oxidase component flavocytochrome b(558), is an in vitro substrate for both a phosphatidic acid-activated kinase and conventional protein kinase C isoforms (Regier, D. S., Waite, K. A., Wallin, R., and McPhail, L. C. (1999) J. Biol. Chem. 274, 36601-36608). Here we show that several neutrophil agonists (phorbol myristate acetate, opsonized zymosan, and N-formyl-methionyl-leucyl-phenylalanine) induce p22(phox) phosphorylation in intact neutrophils. To determine if phospholipase D (PLD) is needed for p22(phox) phosphorylation, cells were pretreated with ethanol, which reduces phosphatidic acid production by PLD in stimulated cells. Phorbol myristate acetate-induced phosphorylation of p22(phox) and NADPH oxidase activity were not reduced by ethanol. In contrast, ethanol reduced both activities when cells were stimulated by N-formyl-methionyl-leucyl-phenylalanine or opsonized zymosan. Varying the time of stimulation with opsonized zymosan showed that the phosphorylation of p22(phox) coincides with NADPH oxidase activation. GF109203X, an inhibitor of protein kinase C and the phosphatidic acid-activated protein kinase, decreased both p22(phox) phosphorylation and NADPH oxidase activity in parallel in opsonized zymosan-stimulated cells. Stimulus-induced phosphorylation of p22(phox) was on Thr residue(s), in agreement with in vitro results. Overall, these data show that NADPH oxidase activity and p22(phox) phosphorylation are correlated and suggest two mechanisms (PLD-dependent and -independent) by which p22(phox) phosphorylation occurs.

- Abstract
Using a phosphorylation-dependent cell-free system to study NADPH oxidase activation (McPhail, L. C., Qualliotine-Mann, D., and Waite, K. A. (1995) Proc. Natl. Acad. Sci. U. S. A. 92, 7931-7935), we previously showed that p47(phox), a cytosolic NADPH oxidase component, is phosphorylated. Now, we show that p22(phox), a subunit of the NADPH oxidase component flavocytochrome b(558), also is phosphorylated. Phosphorylation is selectively activated by phosphatidic acid (PA) versus other lipids and occurs on a threonine residue in p22(phox). We identified two protein kinase families capable of phosphorylating p22(phox): 1) a potentially novel, partially purified PA-activated protein kinase(s) known to phosphorylate p47(phox) and postulated to mediate the phosphorylation-dependent activation of NADPH oxidase by PA and 2) conventional, but not novel or atypical, isoforms of protein kinase C (PKC). In contrast, all classes of PKC isoforms could phosphorylate p47(phox). In a gel retardation assay both the phosphatidic acid-dependent kinase and conventional PKC isoforms phosphorylated all molecules of p22(phox). These findings suggest that phosphorylation of p22(phox) by conventional PKC and/or a novel PA-activated protein kinase regulates the activation/assembly of NADPH oxidase.

- Abstract
• After more than 12 years of development, the ninth edition of the Present State Examination (PSE-9) was published, together with associated instruments and computer algorithm, in 1974. The system has now been expanded, in the framework of the World Health Organization/Alcohol, Drug Abuse, and Mental Health Administration Joint Project on Standardization of Diagnosis and Classification, and is being tested with the aim of developing a comprehensive procedure for clinical examination that is also capable of generating many of the categories of the International Classification of Diseases, 10th edition, and the Diagnostic and Statistical Manual of Mental Disorders, revised third edition. The new system is known as SCAN (Schedules for Clinical Assessment in Neuropsychiatry). It includes the 10th edition of the PSE as one of its core schedules, preliminary tests of which have suggested that reliability is similar to that of PSE-9. SCAN is being field tested in 20 centers in 11 countries. A final version is expected to be available in January 1990.

- Abstract
Several loci on the tumor-inducing plasmid from Agrobacterium tumefaciens were transcriptionally activated in the presence of wounded plant tissue or extracts. The inducible virulence loci were required for efficient tumor formation. In contrast, the plant-inducible locus pinF was not observed to be absolutely essential for virulence. Mutants in pinF showed an attenuated virulence on a variety of dicotyledonous hosts, and this attenuation became more pronounced with decreasing numbers of bacterial cells in the inoculum. The DNA sequence of a 5.5-kilobase region which included the pinF locus from the octopine-type tumor-inducing plasmid A6 was determined. Four open reading frames consistent with the observed transcription of pinF were observed. Two of the open reading frames, pinF1 and pinF2, coded for polypeptides with relative molecular weights of 47,519 (pinF1) and 46,740 (pinF2). A comparison of the amino acid sequences of pinF1 and pinF2 indicated that they were similar to each other and to known polypeptide sequences for cytochrome P-450 enzymes.

- Abstract
The production of cytokinins by plant-associated bacteria was examined by radioimmunoassay. Strains producing trans-zeatin were identified in the genera Agrobacterium and Pseudomonas. Agrobacterium tumefaciens strains containing nopaline tumor-inducing plasmids, A. tumefaciens Lippia isolates, and Agrobacterium rhizogenes strains produced trans-zeatin in culture at 0.5 to 44 micrograms/liter. Pseudomonas solanacearum and Pseudomonas syringae pv. savastanoi produced trans-zeatin at levels of up to 1 mg/liter. In vitro cytokinin biosynthetic activity was measured for representative strains and was found to correlate with trans-zeatin production. The genetic locus for trans-zeatin secretion (tzs) was cloned from four strains: A. tumefaciens T37, A. rhizogenes A4, P. solanacearum K60, and P. syringae pv. savastanoi 1006. Southern blot analysis showed substantial homology of the Agrobacterium tzs genes to each other but not to the two Pseudomonas genes.

- Abstract
The virulence genes of the Agrobacterium tumefaciens Ti plasmid are grouped into six transcription units and direct the transfer of T-DNA into plant cells. We report here the nucleotide sequence of the largest vir operon, virB, from the Ti plasmid pTiA6NC. This operon contains 11 open reading frames, 7 of which show evidence of translational coupling. trpE::virB gene fusions were used to confirm the reading frames of genes virB2, 4, 5, 6, 7, 8, 10, and 11. In addition, the native gene products of virB6 and virB9 were identified using maxicell and in vitro transcription-translation techniques, and the VirB9 protein was found to be proteolytically processed. The codon usage of the predicted virB genes is very similar to the other pTiA6 vir genes and is much less biased than Escherichia coli. Since many of the virB gene products have secretion signals common to exported bacterial proteins, it is likely that they will be membrane-associated. We propose that the VirB proteins are involved in the formation of a transmembrane structure which mediates the passage of the transferred T-DNA molecule through the bacterial and plant cell membranes.

We hope that the ECA Program can make a significant, and perhaps unique, contribution to the field of psychiatric epidemiology and to mental health services research. If the Program provides total true prevalence data on mental disorders according to the latest diagnostic criteria, that in itself will be a significant contribution. Such data should be of enormous benefit to those interested in etiology as well as those interested in health services research. For researchers interested in etiology, the data can be used to identify, by comparison, high-risk groups; for those interested in health services research, the results can serve as a health planning guide that does not depend on the presence or absence of treatment facilities in a given area. Incidence data will be the second major contribution of the ECA Program. Its two-wave design enhances the study of incidence, etiology, and the natural history of disorders and also allows study of the social behavior of persons entering treatment for mental disorders--a subject important to health planners. Finally, a significant result of the ECA Program may be the establishment of a viable standardized methodology for the epidemiologic study of mental disorders by means of which demonstrably replicable results can be produced. Once we demonstrate the equivalence of method and results, then the stage is set for comparative studies of all sorts.

Background Patient decision aids should help people make evidence-informed decisions aligned with their values. There is limited guidance about how to achieve such alignment. Purpose To describe the range of values clarification methods available to patient decision aid developers, synthesize evidence regarding their relative merits, and foster collection of evidence by offering researchers a proposed set of outcomes to report when evaluating the effects of values clarification methods. Data Sources MEDLINE, EMBASE, PubMed, Web of Science, the Cochrane Library, and CINAHL. Study Selection We included articles that described randomized trials of 1 or more explicit values clarification methods. From 30,648 records screened, we identified 33 articles describing trials of 43 values clarification methods. Data Extraction Two independent reviewers extracted details about each values clarification method and its evaluation. Data Synthesis Compared to control conditions or to implicit values clarification methods, explicit values clarification methods decreased the frequency of values-incongruent choices (risk difference, –0.04; 95% confidence interval [CI], –0.06 to –0.02; P < 0.001) and decisional conflict (standardized mean difference, –0.20; 95% CI, –0.29 to –0.11; P < 0.001). Multicriteria decision analysis led to more values-congruent decisions than other values clarification methods (χ2 = 9.25, P = 0.01). There were no differences between different values clarification methods regarding decisional conflict (χ2 = 6.08, P = 0.05). Limitations Some meta-analyses had high heterogeneity. We grouped values clarification methods into broad categories. Conclusions Current evidence suggests patient decision aids should include an explicit values clarification method. Developers may wish to specifically consider multicriteria decision analysis. Future evaluations of values clarification methods should report their effects on decisional conflict, decisions made, values congruence, and decisional regret.

- Abstract
Objectives: A health technology assessment (HTA) does not systematically account for the circumstances and needs of children and youth. To supplement HTA processes, we aimed to develop a child-tailored value assessment framework using a multicriteria decision analysis approach., Methods: We constructed a multicriteria-decision-analysis-based model in multiple phases to create the Comprehensive Assessment of Technologies for Child Health (CATCH) framework. Using a modified Delphi process with stakeholders having broad disciplinary and geographic variation (N = 23), we refined previously generated criteria and developed rank-based weights. We established a criterion-pertinent scoring rubric for assessing incremental benefits of new drugs. Three clinicians independently assessed comprehension by pilotscoring 9 drugs. We then validated CATCH for 2 childhood cancer therapies through structured deliberation with an expert panel (N = 10), obtaining individual scores, consensus scores, and verbal feedback. Analyses included descriptive statistics, thematic analysis, exploratory disagreement indices, and sensitivity analysis., Results: The modified Delphi process yielded 10 criteria, based on absolute importance/relevance and agreed importance (median disagreement indices = 0.34): Effectiveness, Child-specific Health-related Quality of Life, Disease Severity, Unmet Need, Therapeutic Safety, Equity, Family Impacts, Life-course Development, Rarity, and Fair Share of Life. Pilot scoring resulted in adjusted criteria definitions and more precise score-scaling guidelines. Validation panelists endorsed the framework's key modifiers of value. Modes of their individual prescores aligned closely with deliberative consensus scores., Conclusions: We iteratively developed a value assessment framework that captures dimensions of child-specific health and nonhealth gains. CATCH could improve the richness and relevance of HTA decision making for children in Canada and comparable health systems., Competing Interests: Author Disclosures Author disclosure forms can be accessed below in the Supplemental Material section., (Copyright © 2024.

- Abstract
Abstract: Hyperammonemia is a serious clinical condition associated with significant morbidity and mortality. In the pediatric population, this is often caused by urea cycle disorders, acute liver failure, or other less common underlying etiologies. Children and teens with hyperammonemia can have a broad range of clinical findings, including vomiting, respiratory distress, and changes in mental status. As ammonia levels worsen, this presentation can progress to respiratory failure, encephalopathy, cerebral edema, seizures, and death. Given the risk of neurologic damage, timely identification and management of hyperammonemia is critical and includes initial resuscitation, early consultation with subspecialists, and initiation of appropriate therapies. It is important for pediatric emergency medicine providers to understand the clinical findings, causes, diagnosis, and management of hyperammonemia because they play a key role in the provision of effective, multidisciplinary care of these patients., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Introduction: Type 1 pseudohypoaldosteronism (PHA) consists of resistance to aldosterone. Neonatal presentation is characterized by salt wasting, hyperkalemia, and metabolic acidosis with high risk of mortality. Type 1 PHA can be autosomal dominant (renal type 1) or autosomal recessive (systemic type 1). Renal PHA type 1 can be feasibly managed with salt supplementation; however, systemic PHA type 1 tends to have more severe electrolyte imbalance and can be more refractory to treatment., Case Presentation: We present a case of a 3-year-old girl with systemic PHA type 1, diagnosed and confirmed molecularly in infancy, who has been successfully managed with sodium polystyrene sulfonate decanted into feeds along with sodium supplementation. On day 5 of life, a full-term female infant presented to the ED for 2 days of non-bloody, non-bilious emesis, along with hypothermia to 94°F. Laboratory results were notable for hyponatremia (Na) of 127, hyperkalemia (K) of 7.9, and acidosis with bicarbonate level of 11.2. Genetic testing ordered within a week of life confirmed PHA type 1 with a homozygous pathogenic frameshift variant in SCNN1A c.575delA (p.Arg192GlyfsX57). Sodium polystyrene sulfonate and feeds were decanted until the age of 16 months, and she was also continued on NaCl supplementation. She was gradually transitioned to directly administered sodium polystyrene sulfonate without any electrolyte issues. She has overall done well after gastrostomy-tube (G-tube) placement without severe hyperkalemia even with several hospitalizations for gastrointestinal or respiratory illnesses., Discussion/conclusion: A treatment approach to systemic PHA and sodium polystyrene sulfonate administration in neonates and infants is described., Competing Interests: NM has no conflicts of interest with this topic; she is on the advisory board of Pfizer and BioMarin. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Alkhatib, Bartlett, Kanakatti Shankar, Regier and Merchant.)

- Abstract
Purpose: GM1 gangliosidosis (GM1) is an ultra-rare lysosomal storage disease caused by pathogenic variants in galactosidase beta 1 ( GLB1 ; NM_000404), primarily characterized by neurodegeneration, often in children. There are no approved treatments for GM1, but clinical trials using gene therapy (NCT03952637, NCT04713475) and small molecule substrate inhibitors (NCT04221451) are ongoing. Understanding the natural history of GM1 is essential for timely diagnosis, facilitating better supportive care, and contextualizing the results of therapeutic trials., Methods: Forty-one individuals with type II GM1 (n=17 late infantile and n=24 juvenile onset) participated in a single-site prospective observational study. Here, we describe the results of extensive multisystem assessment batteries, including clinical labs, neuroimaging, physiological exams, and behavioral assessments., Results: Classification of 37 distinct variants in this cohort was performed according to ACMG criteria and resulted in the upgrade of six and the submission of four new variants to pathogenic or likely pathogenic. In contrast to type I infantile, children with type II disease exhibited normal or near normal hearing and did not have cherry red maculae or significant hepatosplenomegaly. Some older children with juvenile onset developed thickened aortic and/or mitral valves with regurgitation. Serial MRIs demonstrated progressive brain atrophy that were more pronounced in those with late infantile onset. MR spectroscopy showed worsening elevation of myo-inositol and deficit of N -acetyl aspartate that were strongly correlated with scores on the Vineland Adaptive Behavior Scale and progress more rapidly in late infantile than juvenile onset disease., Conclusion: The comprehensive serial phenotyping of type II GM1 patients expands the understanding of disease progression and clarifies some common misconceptions about type II patients. Findings from this 10-year endeavor are a pivotal step toward more timely diagnosis and better supportive care for patients. The wealth of data amassed through this effort will serve as a robust comparator for ongoing and future therapeutic trials., Competing Interests: Conflict of Interest Disclosure ALH receives consulting fees from Teladoc.

- Abstract
Acute care surgeons encounter patients experiencing surgical emergencies related to advanced malignancy, catastrophic vascular events, or associated with multisystem organ failure. The acute nature is a factor in establishing a relationship between surgeon, patient, and family. Surgeons must use effective communication skills, empathy, and a knowledge of legal and ethical foundations. Training in palliative care principles is limited in many medical school and residency curricula. We offer examples of clinical situations facing acute care surgeons and discuss evidence-based recommendations to facilitate successful treatment and outcomes., (Copyright © 2023 Elsevier Inc.

- Abstract
ATP1A3 encodes the α3 subunit of the sodium-potassium ATPase, one of two isoforms responsible for powering electrochemical gradients in neurons. Heterozygous pathogenic ATP1A3 variants produce several distinct neurological syndromes, yet the molecular basis for phenotypic variability is unclear. We report a novel recurrent variant, ATP1A3(NM_152296.5):c.2324C>T; p.(Pro775Leu), in nine individuals associated with the primary clinical features of progressive or non-progressive spasticity and developmental delay/intellectual disability. No patients fulfil diagnostic criteria for ATP1A3-associated syndromes, including alternating hemiplegia of childhood, rapid-onset dystonia-parkinsonism or cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss (CAPOS), and none were suspected of having an ATP1A3-related disorder. Uniquely among known ATP1A3 variants, P775L causes leakage of sodium ions and protons into the cell, associated with impaired sodium binding/occlusion kinetics favouring states with fewer bound ions. These phenotypic and electrophysiologic studies demonstrate that ATP1A3:c.2324C>T; p.(Pro775Leu) results in mild ATP1A3-related phenotypes resembling complex hereditary spastic paraplegia or idiopathic spastic cerebral palsy. Cation leak provides a molecular explanation for this genotype-phenotype correlation, adding another mechanism to further explain phenotypic variability and highlighting the importance of biophysical properties beyond ion transport rate in ion transport diseases., (Published by Oxford University Press on behalf of the Guarantors of Brain 2023.)

- Abstract
Expensive drugs for rare diseases pose unique economic, evidentiary and ethical challenges, and these will continue to escalate unless steps are taken urgently to address these challenges. We propose concrete actions that all stakeholders (federal and provincial/territorial governments, patients, healthcare providers, the public and drug manufacturers) could take now as a first step toward enhancing sustainability in the use of innovative (albeit expensive) therapies within our publicly funded healthcare system., (Copyright © 2023 Longwoods Publishing.)

- Abstract
There has been explosive growth in the market for expensive drugs for rare diseases (EDRDs). Traditional standards of evidence are not achievable for rare diseases, so lower standards are applied. The price of these drugs is extremely high. This combination of lower standards and higher prices make EDRDs attractive to manufacturers. Legislation designed to incentivize drug development for rare diseases contains loopholes that drive prices up worldwide. Canada compounds those problems with a complex network of agencies that impede communication between those providing market authorization and those purchasing drugs. Drug pricing is not related to metrics like investment or value, but rather willingness to pay. Without high-quality evidence to assess value, we inadvertently prioritize patients with rare diseases over those with common diseases, creating conflict among ethical principles such as social utility, justice and the rule of rescue. Lack of transparency over what is being funded and for whom makes it hard to mitigate challenges through effective policy development. We review the evidentiary, economic and ethical issues around EDRDs and ways to move forward, including enhanced transparency and the development of high-quality evidence to ensure that we do not pay for drugs that do not work., (Copyright © 2023 Longwoods Publishing.)

- Abstract
Background: Recent advances are enabling delivery of precision genomic medicine to cancer clinics. While the majority of approaches profile panels of selected genes or hotspot regions, comprehensive data provided by whole-genome and transcriptome sequencing and analysis (WGTA) present an opportunity to align a much larger proportion of patients to therapies., Patients and Methods: Samples from 570 patients with advanced or metastatic cancer of diverse types enrolled in the Personalized OncoGenomics (POG) program underwent WGTA. DNA-based data, including mutations, copy number and mutation signatures, were combined with RNA-based data, including gene expression and fusions, to generate comprehensive WGTA profiles. A multidisciplinary molecular tumour board used WGTA profiles to identify and prioritize clinically actionable alterations and inform therapy. Patient responses to WGTA-informed therapies were collected., Results: Clinically actionable targets were identified for 83% of patients, of which 37% of patients received WGTA-informed treatments. RNA expression data were particularly informative, contributing to 67% of WGTA-informed treatments; 25% of treatments were informed by RNA expression alone. Of a total 248 WGTA-informed treatments, 46% resulted in clinical benefit. RNA expression data were comparable to DNA-based mutation and copy number data in aligning to clinically beneficial treatments. Genome signatures also guided therapeutics including platinum, poly-ADP ribose polymerase inhibitors and immunotherapies. Patients accessed WGTA-informed treatments through clinical trials (19%), off-label use (35%) and as standard therapies (46%) including those which would not otherwise have been the next choice of therapy, demonstrating the utility of genomic information to direct use of chemotherapies as well as targeted therapies., Conclusions: Integrating RNA expression and genome data illuminated treatment options that resulted in 46% of treated patients experiencing positive clinical benefit, supporting the use of comprehensive WGTA profiling in clinical cancer care., (Copyright © 2022 The Authors.

- Abstract
Purpose: This paper aims to report collective information on safety and efficacy of empagliflozin drug repurposing in individuals with glycogen storage disease type Ib (GSD Ib)., Methods: This is an international retrospective questionnaire study on the safety and efficacy of empagliflozin use for management of neutropenia/neutrophil dysfunction in patients with GSD Ib, conducted among the respective health care providers from 24 countries across the globe., Results: Clinical data from 112 individuals with GSD Ib were evaluated, representing a total of 94 treatment years. The median age at start of empagliflozin treatment was 10.5 years (range = 0-38 years). Empagliflozin showed positive effects on all neutrophil dysfunction-related symptoms, including oral and urogenital mucosal lesions, recurrent infections, skin abscesses, inflammatory bowel disease, and anemia. Before initiating empagliflozin, most patients with GSD Ib were on G-CSF (94/112; 84%). At the time of the survey, 49 of 89 (55%) patients previously treated with G-CSF had completely stopped G-CSF, and another 15 (17%) were able to reduce the dose. The most common adverse event during empagliflozin treatment was hypoglycemia, occurring in 18% of individuals., Conclusion: Empagliflozin has a favorable effect on neutropenia/neutrophil dysfunction-related symptoms and safety profile in individuals with GSD Ib., Competing Interests: Conflict of Interest All authors declare no conflicts of interest., (Copyright © 2022 The Authors.

- Abstract
Background: Peptic ulcer disease (PUD), once primary a surgical problem, is now medically managed in the majority of patients. The surgical treatment of PUD is now strictly reserved for life-threatening complications. Free perforation, refractory bleeding and gastric outlet obstruction, although rare in the age of medical management of PUD, are several of the indications for surgical intervention. The acute care surgeon caring for patients with PUD should be facile in techniques required for bleeding control, bypass of peptic strictures, and vagotomy with resection and reconstruction. This video procedures and techniques article demonstrates these infrequently encountered, but critical operations., Content Video Description: A combination of anatomic representations and videos of step-by-step instructions on perfused cadavers will demonstrate the key steps in the following critical operations. Graham patch repair of perforated peptic ulcer is demonstrated in both open and laparoscopic fashion. The choice to perform open versus laparoscopic repair is based on individual surgeon comfort. Oversewing of a bleeding duodenal ulcer via duodenotomy and ligation of the gastroduodenal artery is infrequent in the age of advanced endoscopy and interventional radiology techniques, yet this once familiar procedure can be lifesaving. Repair of giant duodenal or gastric ulcers can present a challenging operative dilemma on how to best repair or exclude the defect. Vagotomy and antrectomy, perhaps the least common of all the aforementioned surgical interventions, may require more complex reconstruction than other techniques making it challenging for inexperienced surgeons. A brief demonstration on reconstruction options will be shown, and it includes Roux-en-Y gastrojejunostomy., Conclusion: Surgical management of PUD is reserved today for life-threatening complications for which the acute care surgeon must be prepared. This presentation provides demonstration of key surgical principles in management of bleeding and free perforation, as well as gastric resection, vagotomy and reconstruction., Level of Evidence: Video procedure and technique, not applicable., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Patient decision aids should help people make evidence-informed decisions aligned with their values. There is limited guidance about how to achieve such alignment., Purpose: To describe the range of values clarification methods available to patient decision aid developers, synthesize evidence regarding their relative merits, and foster collection of evidence by offering researchers a proposed set of outcomes to report when evaluating the effects of values clarification methods., Data Sources: MEDLINE, EMBASE, PubMed, Web of Science, the Cochrane Library, and CINAHL., Study Selection: We included articles that described randomized trials of 1 or more explicit values clarification methods. From 30,648 records screened, we identified 33 articles describing trials of 43 values clarification methods., Data Extraction: Two independent reviewers extracted details about each values clarification method and its evaluation., Data Synthesis: Compared to control conditions or to implicit values clarification methods, explicit values clarification methods decreased the frequency of values-incongruent choices (risk difference, -0.04; 95% confidence interval [CI], -0.06 to -0.02; P < 0.001) and decisional conflict (standardized mean difference, -0.20; 95% CI, -0.29 to -0.11; P < 0.001). Multicriteria decision analysis led to more values-congruent decisions than other values clarification methods (χ
2 = 9.25, P = 0.01). There were no differences between different values clarification methods regarding decisional conflict (χ2 = 6.08, P = 0.05)., Limitations: Some meta-analyses had high heterogeneity. We grouped values clarification methods into broad categories., Conclusions: Current evidence suggests patient decision aids should include an explicit values clarification method. Developers may wish to specifically consider multicriteria decision analysis. Future evaluations of values clarification methods should report their effects on decisional conflict, decisions made, values congruence, and decisional regret.- Published

- Abstract
The national importance of telemedicine for safe and effective patient care has been highlighted by the current COVID-19 pandemic. Prior to the 2020 pandemic the Division of Genetics and Metabolism piloted a telemedicine program focused on initial and follow-up visits in the patients' home. The goals were to increase access to care, decrease missed work, improve scheduling, and avoid the transport and exposure of medically fragile patients. Visits were conducted by physician medical geneticists, genetic counselors, and biochemical dietitians, together and separately. This allowed the program to develop detailed standard operating procedures. At the onset of the COVID-19 pandemic, this pilot-program was deployed by the full team of 22 providers in one business day. Two physicians remained on-site for patients requiring in-person evaluations. This model optimized patient safety and workforce preservation while providing full access to patients during a pandemic. We provide initial data on visit numbers, types of diagnoses, and no-show rates. Experience in this implementation before and during the pandemic has confirmed the effectiveness and value of telemedicine for a highly complex medical population. This program is a model that can and will be continued well-beyond the current crisis., (© 2020 Wiley Periodicals LLC.)

- Abstract
Despite continuing improvements in the management of classical Hodgkin lymphoma (cHL), relapse remains associated with a risk of lymphoma-related mortality. The biological composition of relapse tumour biopsies shows interpatient variability, which can be leveraged to design prognostic biomarkers. Here, we validated the RHL30 assay, a previously reported gene expression model in an independent cohort of 41 patients with relapsed cHL. Patients classified as high-risk by the RHL30 assay had inferior failure-free survival (FFS) after autologous stem cell transplantation (2-year FFS 41% vs. 92%, P = 0·035). The RHL30 model is a robust biomarker that risk-stratifies patients considered for autologous stem cell transplantation., (© 2020 British Society for Haematology and John Wiley & Sons Ltd.)

- Abstract
Inherited genetic variation has important implications for cancer screening, early diagnosis, and disease prognosis. A role for germline variation has also been described in shaping the molecular landscape, immune response, microenvironment, and treatment response of individual tumors. However, there is a lack of consensus on the handling and analysis of germline information that extends beyond known or suspected cancer susceptibility in large-scale cancer genomics initiatives. As part of the Personalized OncoGenomics program in British Columbia, we performed whole-genome and transcriptome sequencing in paired tumor and normal tissues from advanced cancer patients to characterize the molecular tumor landscape and identify putative targets for therapy. Overall, our experience supports a multidisciplinary and integrative approach to germline data management. This includes a need for broader definitions and standardized recommendations regarding primary and secondary germline findings in precision oncology. Here, we propose a framework for identifying, evaluating, and returning germline variants of potential clinical significance that may have indications for health management beyond cancer risk reduction or prevention in patients and their families., (© The Author(s) 2020.

- Abstract
Importance: Alkaptonuria is an autosomal recessive disorder caused by pathogenic variants in the HGD gene. Deficiency of the HGD enzyme leads to tissue deposition of homogentisic acid (HGA), causing severe osteoarthropathies and cardiac valve degeneration. Although HGD is vital for the catabolism of tyrosine, which provides the basis for thyroid hormone synthesis, the prevalence of thyroid dysfunction in alkaptonuria is unknown., Objective: To assess thyroid structure and function in patients with alkaptonuria., Design, Setting, and Participants: A single-center cohort study was conducted in a tertiary referral center including patients with alkaptonuria followed up for a median of 93 (interquartile range, 48-150) months between February 1, 2000, and December 31, 2018. The alkaptonuria diagnosis was based on clinical presentation and elevated urine HGA levels. A total of 130 patients were considered for participation., Main Outcomes and Measures: Prevalence of thyroid dysfunction in adults with alkaptonuria compared with the general population. Thyrotropin and free thyroxine levels were measured by immunoassay and repeated in each patient a median of 3 (interquartile range, 2-22) times. Neck ultrasonographic scans were analyzed in a subset of participants. Logistic regression was used to test the association of thyroid dysfunction with age, sex, thyroid peroxidase (TPO) antibodies, serum tyrosine levels, and urine HGA levels., Results: Of the 130 patients, 5 were excluded owing to thyroidectomy as the cause of hypothyroidism. The study cohort consisted of 125 patients; the median age was 45 (interquartile range, 35-51) years. Most of the patients were men (72 [57.6%]). The prevalence of primary hyperthyroidism was 0.8% (1 of 125 patients), similar to 0.5% observed in the general population (difference, 0.003; 95% CI, -0.001 to 0.04; P = .88). The prevalence of primary hypothyroidism was 16.0% (20 of 125 patients), which is significantly higher than 3.7% reported in the general population (difference, 0.12; 95% CI, 0.10-0.24; P < .001). Women were more likely to have primary hypothyroidism than men (odds ratio, 10.99; 95% CI, 3.13-38.66; P < .001). Patients with TPO antibodies had a higher likelihood of primary hypothyroidism than those without TPO antibodies (odds ratio, 7.36; 95% CI, 1.89-28.62; P = .004). There was no significant difference in the prevalence of thyroid nodules between patients in this study (29 of 49 [59.2%]) vs the general population (68%) (difference, 0.088; 95% CI, -0.44 to 0.73; P = .20) or of cancer (7% vs 5%; difference, 0.01; 95% CI, -0.01 to 0.17; P = .86)., Conclusions and Relevance: The high prevalence of primary hypothyroidism noted in patients with alkaptonuria in this study suggests that serial screening in this population should be considered and prioritized.

- Abstract
New streamlined models for genetic counseling and genetic testing have recently been developed in response to increasing demand for cancer genetic services. To improve access and decrease wait times, we implemented an oncology clinic-based genetic testing model for breast and ovarian cancer patients in a publicly funded population-based health care setting in British Columbia, Canada. This observational study evaluated the oncology clinic-based model as compared to a traditional one-on-one approach with a genetic counsellor using a multi-gene panel testing approach. The primary objectives were to evaluate wait times and patient reported outcome measures between the oncology clinic-based and traditional genetic counselling models. Secondary objectives were to describe oncologist and genetic counsellor acceptability and experience. Wait times from referral to return of genetic testing results were assessed for 400 patients with breast and/or ovarian cancer undergoing genetic testing for hereditary breast and ovarian cancer from June 2015 to August 2017. Patient wait times from referral to return of results were significantly shorter with the oncology clinic-based model as compared to the traditional model (403 vs. 191 days; p < 0.001). A subset of 148 patients (traditional n = 99; oncology clinic-based n = 49) completed study surveys to assess uncertainty, distress, and patient experience. Responses were similar between both models. Healthcare providers survey responses indicated they believed the oncology clinic-based model was acceptable and a positive experience. Oncology clinic-based genetic testing using a multi-gene panel approach and post-test counselling with a genetic counsellor significantly reduced wait times and is acceptable for patients and health care providers., Competing Interests: Research and funding support was provided by AstraZeneca and research support was provided by BC Cancer and the University of British Columbia.

- Abstract
We report a case of two consecutive pregnancies in the same couple presenting with very low pregnancy-associated plasma protein A (PAPP-A), with both pregnancies affected by multiple anomalies of a similar phenotype identified during mid-trimester ultrasound, and eventual diagnosis of Peters-plus syndrome. This case is important in expanding the differential for very low PAPP-A. It also demonstrates the diagnostic value of whole-exome sequencing (WES) after prenatal diagnosis of recurrent fetal ultrasonographic findings. The importance and complexity of providing patient education to enable informed consent for next generation sequencing technologies is discussed.

- Abstract
Inborn errors of metabolism (IEM), although individually rare, occur in 1 out of every 1,500 births. The first opportunity to detect IEM occurs during preconception counseling, when pregnant women and couples considering future pregnancies can undergo carrier screening. For individuals of all ethnic backgrounds, the screening includes testing for a variety of IEM and non-IEM. For individuals of Ashkenazi Jewish descent, carrier screening, per the American College of Medical Genetics and Genomics, also includes testing for Tay-Sachs disease and four other IEM. Inborn errors of metabolism can present in utero; in newborns; or in children, adolescents, and adults. Some IEM can be detected in utero with the use of ultrasonography. Most commonly, IEM are detected at newborn screening. Expanded newborn screening, which now includes 34 core conditions, allows for diagnosis in the newborn period and provides the opportunity for early institution of available treatments. However, some newborns present with symptoms consistent with an IEM before the availability of pending newborn screening results or present with symptoms attributable to an IEM not detectable with screening. Such situations are medical emergencies requiring immediate consultation with a metabolic specialist. If a delay occurs in obtaining consultation, initial treatment involves discontinuing feeding and providing high-rate glucose infusions. Some IEM present later in life. Children may develop and present with dysmorphic facial features. In some cases, symptoms may not appear until adolescence or adulthood when patients have residual enzyme activity that allows for slow accumulation of toxic molecules over time. Long-term treatments are effective for some IEM. Treatments include dietary restrictions and enzyme-replacement therapies.

- Abstract
Background: Spending on cancer drugs has risen dramatically in recent years compared to other areas of health care, due in part to higher prices associated with newly approved drugs and increased demand for these drugs. Addressing this situation requires making difficult trade-offs between cost, harms, and ability to benefit when using public resources, making it important for policy makers to have input from many people affected by the issue, including citizens., Methods: In September 2014, a deliberative public engagement event was conducted in Vancouver, British Columbia (BC), on the topic of priority setting and costly cancer drugs. The aim of the study was to gain citizens' input on the topic and have them generate recommendations that could inform cancer drug funding decisions in BC. A market research company was engaged to recruit members of the BC general public to deliberate over two weekends (four days) on how best to allocate resources for expensive cancer treatments. Participants were stratified based on the 2006 census data for BC. Participants were asked to discuss disinvestment, intravenous versus oral chemotherapy delivery, and decision governance. All sessions were audio recorded and transcribed. Transcripts were analyzed using NVivo 11 software., Results: Twenty-four individuals participated in the event and generated 30 recommendations. Participants accepted the principle of resource scarcity and the need of governments to make difficult trade-offs when allocating health-care resources. They supported the view that cost-benefit thresholds must be set for high-cost drugs. They also expected reasonable health benefits in return for large expenditures, and supported the view that some drugs do not merit funding. Participants also wanted drug funding decisions to be made in a non-partisan and transparent way., Conclusion: The recommendations from the Vancouver deliberation can provide guidance to policy makers in BC and may be useful in challenging pricing by pharmaceutical companies.
