Abstract
Background Obtaining complete and accurate information in recruitment registries is essential for matching potential participants to research studies for which they qualify. Since electronic health record (EHR) systems are required to make patient data available to external systems, an interface between EHRs and recruitment registries may improve accuracy and completeness of volunteers' profiles. We tested this hypothesis on ResearchMatch (RM), a disease- and institution-neutral recruitment registry with 1357 studies across 255 institutions. Methods We developed an interface where volunteers signing up for RM can authorize transfer of demographic data, medical conditions, and medications from the EHR into a registration form. We obtained feedback from a panel of community members to determine acceptability of the planned integration. We then developed the EHR interface and performed an evaluation study of 100 patients to determine whether RM profiles generated with EHR-assisted adjudication included more conditions and medications than those without the EHR connection. Results Community member feedback revealed that members of the public were willing to authenticate into the EHR from RM with proper messaging about choice and privacy. The evaluation study showed that out of 100 participants, 75 included more conditions and 69 included more medications in RM profiles completed with the EHR connection than those without. Participants also completed the EHR-connected profiles in 16 fewer seconds than non-EHR-connected profiles. Conclusions The EHR to RM integration could lead to more complete profiles, less participant burden, and better study matches for many of the over 148,000 volunteers who participate in ResearchMatch.

Abstract
New technologies and disruptions related to Coronavirus disease-2019 have led to expansion of decentralized approaches to clinical trials. Remote tools and methods hold promise for increasing trial efficiency and reducing burdens and barriers by facilitating participation outside of traditional clinical settings and taking studies directly to participants. The Trial Innovation Network, established in 2016 by the National Center for Advancing Clinical and Translational Science to address critical roadblocks in clinical research and accelerate the translational research process, has consulted on over 400 research study proposals to date. Its recommendations for decentralized approaches have included eConsent, participant-informed study design, remote intervention, study task reminders, social media recruitment, and return of results for participants. Some clinical trial elements have worked well when decentralized, while others, including remote recruitment and patient monitoring, need further refinement and assessment to determine their value. Partially decentralized, or "hybrid" trials, offer a first step to optimizing remote methods. Decentralized processes demonstrate potential to improve urban-rural diversity, but their impact on inclusion of racially and ethnically marginalized populations requires further study. To optimize inclusive participation in decentralized clinical trials, efforts must be made to build trust among marginalized communities, and to ensure access to remote technology.

Abstract
CONTEXT Interruption of the renin-angiotensin-aldosterone system prevents incident diabetes in high-risk individuals, although the mechanism remains unclear. OBJECTIVE To test the hypothesis that activation of the endogenous renin-angiotensin-aldosterone system or exogenous aldosterone impairs insulin secretion in humans. DESIGN We conducted a randomized, blinded crossover study of aldosterone vs vehicle and compared the effects of a low-sodium versus a high-sodium diet. SETTING Academic clinical research center. PARTICIPANTS Healthy, nondiabetic, normotensive volunteers. INTERVENTIONS Infusion of exogenous aldosterone (0.7 μg/kg/h for 12.5 h) or vehicle during low or high sodium intake. Low sodium (20 mmol/d; n = 12) vs high sodium (160 mmol/d; n = 17) intake for 5-7 days. MAIN OUTCOME MEASURES Change in acute insulin secretory response assessed during hyperglycemic clamps while in sodium balance during a low-sodium vs high-sodium diet during aldosterone vs vehicle. RESULTS A low-sodium diet increased endogenous aldosterone and plasma renin activity, and acute glucose-stimulated insulin (-16.0 ± 5.6%; P = .007) and C-peptide responses (-21.8 ± 8.4%; P = .014) were decreased, whereas the insulin sensitivity index was unchanged (-1.0 ± 10.7%; P = .98). Aldosterone infusion did not affect the acute insulin response (+1.8 ± 4.8%; P = .72) or insulin sensitivity index (+2.0 ± 8.8%; P = .78). Systolic blood pressure and serum potassium were similar during low and high sodium intake and during aldosterone infusion. CONCLUSIONS Low dietary sodium intake reduces insulin secretion in humans, independent of insulin sensitivity.

Abstract
Renin-angiotensin-aldosterone system blockade reduces the incidence of type 2 diabetes in clinical trials. We previously demonstrated that aldosterone impairs insulin secretion via a direct beta-cell effect in mice. To test the hypothesis that aldosterone and the mineralocorticoid receptor contribute to impaired insulin secretion in humans, we enrolled subjects with metabolic syndrome treated with hydrochlorothiazide (HCTZ) 12.5 mg daily for 4 weeks (baseline) followed by either Spironolactone 25 mg daily (SPL, n=16) versus Aliskiren 150 mg daily (ALI, n=19) for 4 weeks. We assessed insulin secretion and sensitivity using hyperglycemic clamps during sodium controlled diet (160 mmol Na).
During HCTZ alone, plasma aldosterone correlated inversely with the initial insulin response and disposition index (Figure A), but not with insulin sensitivity index. Plasma aldosterone decreased during aliskiren (-1.5±0.78 ng/dL) and increased during spironolactone treatment (+4.0±0.8 ng/dL; p<0.001 between treatment). Blood pressure, serum potassium, and insulin sensitivity index were unchanged. The acute insulin response increased compared to baseline during SPL compared to ALI (+11.6±7.9 vs -10.7±7.7 μU/mL; p=0.048), whereas insulin sensitivity index was unchanged.
We conclude that aldosterone is inversely associated with the initial phase insulin secretory response, the earliest detectable change in impaired glucose tolerance. Treatment with spironolactone could improve glucose homeostasis by restoring insulin secretion in subjects with metabolic syndrome.

Abstract
Early-generation β-blockers lower blood pressure and reduce cardiovascular morality in coronary artery disease and congestive heart failure but worsen glucose homeostasis and fibrinolytic balance. Nebivolol is a third-generation β-blocker that increases the bioavailability of nitric oxide. We compared the effect of nebivolol (5 mg/d) and the β(1)-selective antagonist metoprolol (100 mg/d) on glucose homeostasis and markers of fibrinolysis in 46 subjects with metabolic syndrome. Subjects underwent a frequently sampled IV glucose tolerance test after 3-week washout and placebo treatment and after randomized treatment with study drug. After 12-week treatment, nebivolol and metoprolol equivalently decreased systolic blood pressure, diastolic blood pressure, and heart rate. Neither drug affected β-cell function, disposition index, or acute insulin response to glucose. Metoprolol significantly decreased the insulin sensitivity index. In contrast, nebivolol did not affect insulin sensitivity, and the decrease in sensitivity was significantly greater after metoprolol than after nebivolol (-1.5±2.5×10(-4)×min(-1) per milliunit per liter versus 0.04±2.19×10(-4)×min(-1) per milliunit per liter after nebivolol; P=0.03). Circulating plasminogen activator inhibitor also increased after treatment with metoprolol (from 9.8±6.8 to 12.3±7.8 ng/mL) but not nebivolol (from 10.8±7.8 to 10.5±6.2 ng/mL; P=0.05 versus metoprolol). Metoprolol, but not nebivolol, increased F(2)-isoprostane concentrations. In summary, treatment with metoprolol decreased insulin sensitivity and increased oxidative stress and the antifibrinolytic plasminogen activator inhibitor 1 in patients with metabolic syndrome, whereas nebivolol lacked detrimental metabolic effects. Large clinical trials are needed to compare effects of nebivolol and the β(1) receptor antagonist metoprolol on clinical outcomes in patients with hypertension and the metabolic syndrome.

Abstract
BACKGROUND Defects in the handling of renal salt reabsorption may contribute to interindividual differences in blood-pressure regulation and susceptibility to hypertension. Sodium chloride reabsorption in the thick ascending limb (TAL) is dependent in part on the chloride channel, ClC-Kb (encoded by CLCNKB), and its accessory subunit, barttin (encoded by BSND). METHODS We investigated genetic variations in BSND in a screening population, and genotyped a homogenous cohort of normotensive and hypertensive Ghanaian subjects, in addition to four ethnically defined control populations. Functional consequences of the identified BSND variants were examined using a heterologous expression system. RESULTS Three novel, nonsynonymous coding-sequence single-nucleotide polymorphisms were identified (V43I, E255Q, and G284D) in the screening population. BSND-V43I was identified in African American, Asian, and Hispanic subjects, with minor allele frequencies of 0.14, 0.18, and 0.01, respectively, but it was absent in the Caucasian population. BSND-E225Q and BSND-G284D were rare variants. Two of these variants (V43I and G284D) exhibited partial loss-of-function phenotypes when heterologously expressed with ClC-Kb chloride channels in cultured cells. In logistic regression analyses, we observed no association between hypertension and BSND-I43 in our study population. However, we did observe significant deviation from Hardy-Weinberg equilibrium in the normotensive population. CONCLUSIONS We conclude that BSND-V43I, a common variant conferring partial loss of function, exhibits significant deviation from Hardy-Weinberg equilibrium in the Ghanaian normotensive control population. However, it does not independently confer protection against hypertension.

Abstract
Prostaglandin (PG)E2 is a major cyclooxygenase (COX) product that is important in human physiology and pathophysiology. Quantification of systemic PG production in humans is best assessed by measuring excreted urinary metabolites. Accurate and easy-to-perform assays to quantify the major urinary metabolite of PGE2, 11alpha-hydroxy-9,15-dioxo-2,3,4,5-tetranor-prostane-1,20-dioic acid (PGE-M), do not exist. We now report the development of a robust and facile method to measure urinary PGE-M excretion in humans using stable isotope dilution techniques employing liquid chromatography/tandem mass spectrometry (LC/MS/MS). Concentrations of the metabolite in urine from healthy humans are nearly twofold greater in men than in women (10.4+/-1.5 vs. 6.0+/-0.7 ng/mg creatinine). Levels of PGE-M in healthy humans are suppressed significantly not only by the nonselective COX inhibitor ibuprofen but also by the COX-2 selective inhibitor rofecoxib, suggesting that the majority of PGE2 formed in vivo is derived from COX-2. Increased COX-2 expression and increased PGE2 production are associated with malignancy. Levels of PGE-M were found to be greatly increased in humans with unresectable non-small cell cancer of the lung, and this increase is dramatically reduced by administration of the COX-2 inhibitor celecoxib, implying that COX-2 contributes significantly to the overproduction of PGE2. In summary, quantification of PGE-M using LC/MS/MS provides a facile and accurate method to assess PGE2 formation in human physiological and pathophysiological processes.

Abstract
Activities of daily living scales can be a useful tool in assessing change in people with dementia, either as the disease progresses or in response to treatment. However, little data exist as to the sensitivity to change of instruments used. The Bristol Activities of Daily Living Scale was developed with assistance from the carers of community dwelling people with dementia to be completed by such people and has been shown to have internal consistency as well as face and construct validity. This study aimed to analyse the sensitivity to change of the Bristol Activities of Daily Living Scale in people with Alzheimer's disease receiving anticholinesterase medication. Using the Clinician's Global Rating of Change as a gold standard for change, differences between Bristol Activities of Daily Living Scale scores before and after medication were compared with change in Mini-Mental State Examination, Alzheimer's Disease Assessment Scale - Cognitive and the Nurses Observation Scale for Geriatric Patients, in 61 older adults receiving anticholinesterase medication for Alzheimer's disease. Both the Bristol Activities of Daily Living Scale and the Nurses Observation Scale for Geriatric Patients are sensitive and specific in predicting improvement or stability as measured by the clinician's global rating of change. However, unlike the Nurses Observation Scale for Geriatric Patients, change over time in the Bristol Activities of Daily Living Scale significantly correlates with change in the Mini-Mental State Examination and the Alzheimer's Disease Assessment Scale - Cognitive. The Bristol Activities of Daily Living Scale is sensitive to change in activities of daily living and shows the expected and desirable relationship with measures of cognition.

Abstract
The Bristol Memory Disorders Clinic uses the Weigl Color Form Sorting Test (CFST) to appraise abstraction and the ability to shift set. The original scoring system for the CFST (Grewal & Haward, 1984), developed on the premise that sorting to form is more difficult than sorting to color, had no score for an individual able to sort to form and subsequently unable to shift to color with a cue. Clinical experience suggested that the performance of some individuals required such a score. A new scoring system was developed and validated in a memory-disorders-clinic sample. The validation showed the new score to be necessary and gave support to the original premise that people with organic brain damage show a preference for sorting to color.

Abstract
The estrogen receptor (ER) binds with high affinity to the nonclassical estrogen response elements (ERE) found in the rat prolactin gene. There are two putative EREs in this gene; at -1582 and -1722 upstream of the transcriptional start site. We used DNA binding assays based on the immunoprecipitation of receptor with bound DNA to quantitate the binding of ER to these two elements. ER bound each element with significantly higher affinity than it bound to nonspecific DNA, but with 10-100-fold less affinity than that for the classical ERE sequence derived from the vitellogenin A2 gene. These comparisons rank the prolactin gene sequences as weak EREs. We also observed a 1:1 ratio of ER to ERE in the bound complexes, indicating that these high-affinity interactions were not dependent upon an ER homodimer. These data support the role of these sequences in mediating estrogen regulation of the prolactin gene.

Abstract
We added phenylpropanolamine OROS (Acutrim; Ciba-Geigy Corp.) or placebo to a physician-managed behavior modification, mild caloric restriction, and exercise weight control program. One hundred six healthy, overweight (115% to 130% ideal body weight) women participated in this 14-week double-blind clinical trial. On average, the participants who took Acutrim lost significantly more weight (X +/- SE; 6.1 +/- 0.6 kg; 8.0% +/- 0.8%) than did those taking placebo (4.3 +/- 0.7 kg; 5.5% +/- 0.8%; P less than 0.05). Those taking Actrim continued to lose weight over the Christmas holiday, while the placebo group gained weight. Fifteen participants taking placebo withdrew, three because of adverse drug reactions (ADRs). Thirteen of 53 participants in the Acutrim group left the study, two because of ADRs. Dry mouth was the most frequent complaint from participants taking Acutrim. No serious cardiovascular effects occurred. Both complaints and the number of participants reporting ADRs decreased with continued dosing. We conclude that Acutrim is a safe, modestly effective adjunct to a physician-managed, integrated weight control program.
