Diagnostic findings in sinonasal aspergillosis in dogs in the United Kingdom: 475 cases (2011-2021). J Small Anim Pract 2024. [PMID: 38679786 DOI: 10.1111/jsap.13736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 02/28/2024] [Accepted: 03/31/2024] [Indexed: 05/01/2024]
Abstract
OBJECTIVES To describe the diagnostic tests used and their comparative performance in dogs diagnosed with sinonasal aspergillosis in the United Kingdom. A secondary objective was to describe the signalment, clinical findings and common clinicopathologic abnormalities in sinonasal aspergillosis. MATERIALS AND METHODS A multi-centre retrospective survey was performed involving 23 referral centres in the United Kingdom to identify dogs diagnosed with sinonasal aspergillosis from January 2011 to December 2021. Dogs were included if fungal plaques were seen during rhinoscopy or if ancillary testing (via histopathology, culture, cytology, serology or PCR) was positive and other differential diagnoses were excluded. RESULTS A total of 662 cases were entered into the database across the 23 referral centres. Four hundred and seventy-five cases met the study inclusion criteria. Of these, 419 dogs had fungal plaques and compatible clinical signs. Fungal plaques were not seen in 56 dogs with turbinate destruction that had compatible clinical signs and a positive ancillary test result. Ancillary diagnostics were performed in 312 of 419 (74%) dogs with observed fungal plaques permitting calculation of sensitivity of cytology as 67%, fungal culture 59%, histopathology 47% and PCR 71%. CLINICAL SIGNIFICANCE The sensitivities of ancillary diagnostics in this study were lower than previously reported challenging the clinical utility of such tests in sinonasal aspergillosis. Treatment and management decisions should be based on a combination of diagnostics including imaging findings, visual inspection, and ancillary testing, rather than ancillary tests alone.

Abstract
Truncated thioester N,S-diacetylcysteamine (SNAc) was utilised as a co-factor mimic for PseH, an acetyl-coA dependent aminoglycoside N-acetyltransferase, in the biosynthesis of the bacterial sugar, pseudaminic acid. Additionally, an azido-SNAc analogue was used to smuggle N7-azide functionality into the pseudaminic acid backbone, facilitating its use as a reporter of pseudaminyltransferase activity.

Etiologies of nontraumatic feline uveitis in the UK: A retrospective observational study of 72 cats. Open Vet J 2023; 13:1195-1204. [PMID: 37842107 PMCID: PMC10576583 DOI: 10.5455/ovj.2023.v13.i9.15] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 08/30/2023] [Indexed: 10/17/2023] Open
Abstract
Background Uveitis is a common ophthalmic diagnosis in cats, that can lead to discomfort and loss of vision. Identification of nonidiopathic cases facilitates treatment and could reduce morbidity associated with this condition. Aim To evaluate etiologies of nontraumatic uveitis in the UK, to compare diagnostic features between idiopathic cases and those with an established underlying etiology, and to investigate the association of clinical signs and abnormal diagnostic findings with a confirmed etiology. Methods Records of cats diagnosed with uveitis at a UK referral center between August 2009 and April 2018 were retrospectively reviewed, excluding traumatic (and reflex) cases. Cases were categorized based on whether an underlying etiology had been established in cases with confirmed etiology, idiopathic, and inconclusive cases. All cases had a minimum of 12-month follow-up unless an underlying etiology had been established. Population characteristics, clinical signs, diagnostic investigation features, and results were reported. Results 72 cases of uveitis were included, of which male cats and domestic breeds were overrepresented. An underlying etiology was determined in 23.6% of cases: 9.7% had infectious diseases, 5.6% had systemic neoplasia, 4.2% had primary ocular neoplasia, and 4.2% had metabolic disease. Idiopathic uveitis comprised 37.5% of cases, and the remaining 38.9% were inconclusive, of which 35.7% died or were euthanased within the follow-up period. Among the study population, no significant age difference was found between cats with idiopathic disease or confirmed etiology. The unilateral disease was reported in 56.9% of cases and was not different across the idiopathic cases and confirmed etiology groups. The most common ophthalmic clinical sign was an aqueous flare, followed by keratic precipitates and hypotony. Iris color change (p = 0.015) and the presence of an intraocular mass (p = 0.025) were associated with an underlying etiology. Conclusion Idiopathic uveitis was found to be the most common diagnosis in this study population. However, a similar proportion of cases had possible underlying etiologies as a high proportion manifested systemic disease within the follow-up time. An underlying etiology could be established only in a quarter of cases. Further studies are required to standardize the investigations required when assessing cats with uveitis to minimize patient morbidity.

Data-driven preoperative hemoglobin thresholds in patients undergoing Bilateral simultaneous total Knee arthroplasty are similar to patients undergoing unilateral total Knee arthroplasty. Knee 2023; 42:258-263. [PMID: 37105013 DOI: 10.1016/j.knee.2023.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 01/21/2023] [Accepted: 03/02/2023] [Indexed: 04/29/2023]
Abstract
INTRODUCTION Preoperative anemia is a risk factor for transfusions and complications following total knee arthroplasty (TKA). Bilateral TKA (bTKA) is more extensive compared to unilateral TKA (uTKA) and a higher preoperative hemoglobin threshold may be warranted. We hypothesized that the optimal hemoglobin cutoff value which predicts the need for postoperative transfusion would be higher for bTKA than uTKA. METHODS We conducted a case control study using a national database and identified patients undergoing primary TKA from 2010-2020. 1:1, nearest-neighbor propensity-score matching was used to create a cohort of patients undergoing uTKA matched with patients undergoing bTKA based on age, gender, Charlston Comorbidity Index (CCI), and American Society of Anesthesiology (ASA) classification. After 2015, NSQIP discontinued collection of the variables MI, angina, and hemiplegia. Thus, the accuracy of CCI, which was used as a matching variable, will be less accurate after 2015. To explore this limitation further, a sensitivity analysis was performed excluding data after 2015 and there was no change in the significance of our primary outcomes. Hemoglobin thresholds which maximally predict postoperative transfusion risk and 30-day complications were identified using Youden's index. Significance was considered if 95% CI's were non-overlapping. RESULTS 9,891 patients were included in each of the bTKA and uTKA cohorts with successful 1:1 matching (p > 0.05 for all criteria). 3.216 (16 %) of patients received a transfusion in the postoperative period. Hemoglobin values which predict postoperative transfusions were not significantly different between uTKA and bTKA for both female and male groups. In females, the preoperative hemoglobin threshold was 12.8 g/dL (95 % CI: 12.2-13.3) in patients undergoing bTKA and 12.7 g/dL (95 % CI: 12.2 - 13.2) in uTKA. In males, the threshold was 13.9 (95 % CI: 13.7-14.2) in patients undergoing bTKA and 13.1 g/dL (95 % CI: 12.5-13.8) in patients undergoing uTKA. CONCLUSIONS Preoperative hemoglobin values which maximally predict postoperative transfusion risk following uTKA and bTKA are similar without significant differences.

Validation of the Knowledge of Genome Sequencing (KOGS) scale in cancer patients. PATIENT EDUCATION AND COUNSELING 2022; 105:3110-3115. [PMID: 35738962 DOI: 10.1016/j.pec.2022.06.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 06/09/2022] [Accepted: 06/13/2022] [Indexed: 06/15/2023]
Abstract
INTRODUCTION The Knowledge of Genome Sequencing (KOGS) questionnaire was recently developed to measure knowledge of genomic sequencing (GS), with preliminary psychometric data supporting its reliability and validity. The aim of this study was to test the reliability and validity of the KOGS in a larger sample, and to confirm its utility in a cancer setting. METHODS The Genetic Cancer Risk in the Young (RisC) study recruits participants with a personal history of cancer, to investigate heritable cancer causes and future cancer risk using germline GS. Participants (n = 261) in a psychosocial substudy of RisC completed a questionnaire after consent to RisC but before GS, including the KOGS, the Intolerance of Uncertainty Scale, the Chew health literacy scale and items assessing demographic and disease variables. Confirmatory factor analysis (CFA), Cronbach alpha and correlational analyses were undertaken. RESULTS The CFA testing a single-factor model yielded a good model fit, χ2/df = 2.43, comparative fit index (CFI) = 0.97, root mean square error of approximation (RMSEA) = 0.07 and weighted mean root square (WRMR) = 1.03. Factor loadings of all items were above 0.60 and ranged between.66 and.93. The single factor score demonstrated excellent internal consistency (α = 0.82). KOGS scores were significantly associated with health literacy (r = 0.23, p < .001), having a university education [t(258) = -4.53, p < .001] and having a medical or science background [t(259) = -3.52, p < .001] but not with speaking a language other than English at home, time since diagnosis, previous genetic counselling/testing or intolerance of uncertainty. DISCUSSION This study confirmed a single-factor structure for the KOGS, and its reliability and validity in a cancer population. Associations with measures of health literacy and education were significant and positive as expected, supporting the KOG's construct validity. Previous genetic counselling may not be sufficient to provide specific knowledge of GS.

Abstract
OBJECTIVE Cancer patients, carers and oncology health professionals have been impacted by the COVID-19 pandemic in many ways, but their experiences and psychosocial responses to the pandemic are still being explored. This study aimed to document the experience of Australians living with cancer, family carers, and Oncology health professionals (HPs) when COVID-19 first emerged. METHODS In this qualitative study, participants (cancer patients currently receiving treatment, family carers and HPs) completed a semi-structured interview exploring their experiences of COVID-19 and the impact it had on cancer care. Participants also completed the Hospital Anxiety and Depression Scale (patients) and the Depression, Anxiety and Stress Scale (carers and HPs) to assess emotional morbidity. Thematic analysis was undertaken on qualitative data. RESULTS 32 patients, 16 carers and 29 HPs participated. Qualitative analysis yielded three shared themes: fear and death anxiety, isolation, and uncertainty. For HPs, uncertainty incorporated the potential for moral distress and work-stress. Patients and carers scoring high on anxiety/depression measures were more likely to have advanced disease, expressed greater death anxiety, talked about taking more extreme precautionary measures, and felt more impacted by isolation. CONCLUSION Cancer and COVID-19 can have compounding psychological impacts on all those receiving or giving care. PRACTICE IMPLICATIONS Screening for distress in patients, and burnout in HPs, is recommended. Increased compassionate access and provision of creative alternatives to face-to-face support are warrented.

Phenobarbital-induced autoimmune haemolytic anaemia, thrombocytopenia and peripheral lymphadenomegaly due to reactive lymphoid hyperplasia in a cat. JFMS Open Rep 2022; 8:20551169221079238.

Abstract
Case summary A female neutered domestic longhair cat, aged 1 year and 5 months, presented with lymphadenomegaly and anaemia following therapy with phenobarbital for idiopathic epilepsy. Physical examination revealed pale pink mucous membranes and peripheral lymphadenomegaly. Haematology showed a regenerative anaemia (haematocrit 19.3%, reticulocyte count 118.08 ×109/l), and saline agglutination was positive. Infectious disease screening was negative and lymph node cytology was consistent with reactive lymphoid hyperplasia. A diagnosis of phenobarbital-induced reactive lymphoid hyperplasia and immune-mediated anaemia was suspected. Complete resolution of the lymphadenomegaly and anaemia was documented within 4 weeks of phenobarbital discontinuation. Relevance and novel information There are limited case reports of phenobarbital-induced haematological changes and lymphadenomegaly; however, the combination has not previously been reported in cats and is similar to the rare but significant syndrome in humans known as ‘anticonvulsant hypersensitivity syndrome’. Anticonvulsant hypersensitivities should be considered as a potentially serious, yet reversible, sequela to phenobarbital treatment that may be mistaken for more severe illness such as neoplasia.

Abstract
Pseudaminic acids (Pses) are a group of non-mammalian nonulosonic acids (nulOs) that have been shown to be an important virulence factor for a number of pathogenic bacteria, including emerging multidrug-resistant ESKAPE pathogens. Despite their discovery over 30 years ago, relatively little is known about the biological significance of Pse glycans compared with their sialic acid analogues, primarily due to a lack of access to the synthetically challenging Pse architecture. Recently, however, the Pse backbone has been subjected to increasing synthetic exploration by carbohydrate (bio)chemists, and the total synthesis of complex Pse glycans achieved with inspiration from the biosynthesis and subsequent detailed study of chemical glycosylation by using Pse donors. Herein, context is provided for these efforts by summarising recent synthetic approaches pioneered for accessing Pse glycans, which are set to open up this underexplored area of glycoscience to the wider scientific community.

Protestant Christian attitudes to ART. Hum Reprod Open 2019; 2019:hoz018.

Abstract
STUDY QUESTION How do Christian religious beliefs affect attitudes to ART? SUMMARY ANSWER Attitudes to ART depend on the religiosity of the respondent, and although the majority of those that had successfully used ART were positive or moderately positive in their views, the acceptability of procedures fell when damage to the marriage relationship or the embryo was a potential outcome. WHAT IS KNOWN ALREADY Religion can impact views on ART. Sanctity of marriage and sanctity of the embryo are major concerns for some Christians, but details are unclear. METHODS A cross-sectional online survey was used to collect data from 1587 participants over a 3-month period in 2013, of which 1334 were of the Christian faith and included in this study. Descriptive statistics were reported for individual ARTs, and a general score of all ART approval was calculated. A multivariable linear and logistic regression was conducted on general approval for ART to identify predictors of ART approval. MAIN RESULTS AND THE ROLE OF CHANCE Indicators of religiosity (religious meeting attendance and Bible reading frequency) showed that this was a highly religious sample. We found that in this cohort of English-speaking, well-educated, practising and mainly Protestant Christians 164 (12.3%) of those had personal experience of ART. Most participants that had successfully used ART were positive or moderately positive in their views. Throughout the cohort, procedures were less acceptable if there was a perception that the marriage relationship or the life of the embryo was threatened: including donated gametes (28.7-29.1% approval), surrogacy (22.7-33.1% approval), and PGD (1.0-23.8% approval). A multivariable analysis of the ART approval score found that it was higher among those with Protestant compared with Catholic/Orthodox faith (P < 0.001; mean score difference, 5.06; 95% CI 4.36-5.81) and those who believe life begins after fertilisation (P < 0.001; mean score difference, 4.86; 95% CI 4.14-5.57). Approval was also higher, but to a lesser extent, in women than men (P = 0.008; mean score difference, 0.73; 95% CI 0.18-1.28), and those with lower religiosity (P < 0.001). The area raising most indecision for this cohort was disposal of excess embryos. LIMITATIONS REASONS FOR CAUTION This sample includes an uneven geographical spread of respondents and restriction to English-speaking participants. Different views may be expressed by a different religious cohort. Use of an online survey platform means that a bias towards those with computers (consistent with education levels of this cohort) could exist. Use of this platform also makes it impossible to know the response rate, and the veracity of responses cannot be verified. However, despite these limitations we believe this survey gives us insight into the reservations held among a certain population of Christians regarding the use of reproductive technology. WIDER IMPLICATIONS OF THE FINDINGS Our findings highlight the need for ART clinicians to consider the influence of patient spiritual beliefs on therapeutic options and provide detailed information that will allow them to be accommodated. Practices such as widening the options for collecting semen and limiting the number of embryos created through IVF so as to reduce or eliminate excess embryos may be helpful for these patients. STUDY FUNDING/COMPETING INTERESTS This study was supported by a grant from The Center for Bioethics & Human Dignity in Deerfield, Illinois, USA. The authors have no conflicts of interest to declare.

Abstract
BACKGROUND Data on dermatological manifestations of Noonan syndrome (NS) remain heterogeneous and are based on limited dermatological expertise. OBJECTIVES To describe the dermatological manifestations of NS, compare them with the literature findings, and test for dermatological phenotype-genotype correlations with or without the presence of PTPN11 mutations. METHODS We performed a large 4-year, prospective, multicentric, collaborative dermatological and genetic study. RESULTS Overall, 129 patients with NS were enrolled, including 65 patients with PTPN11-NS, 34 patients with PTPN11-NS with multiple lentigines (NSML), and 30 patients with NS who had a mutation other than PTPN11. Easy bruising was the most frequent dermatological finding in PTPN11-NS, present in 53·8% of patients. Multiple lentigines and café-au-lait macules (n ≥ 3) were present in 94% and 80% of cases of NSML linked to specific mutations of PTPN11, respectively. Atypical forms of NSML could be associated with NS with RAF1 or NRAS mutations. In univariate analysis, patients without a PTPN11 mutation showed (i) a significantly higher frequency of keratinization disorders (P = 0·001), including keratosis pilaris (P = 0·005), ulerythema ophryogenes (P = 0·0001) and palmar and/or plantar hyperkeratosis (P = 0·06, trend association), and (ii) a significantly higher frequency of scarce scalp hair (P = 0·035) and scarce or absent eyelashes (P = 0·06, trend association) than those with PTPN11 mutations. CONCLUSIONS The cutaneous phenotype of NS with a PTPN11 mutation is generally mild and nonspecific, whereas the absence of a PTPN11 mutation is associated with a high frequency of keratinization disorders and hair abnormalities.

Abstract
BACKGROUND Data on dermatological manifestations of cardiofaciocutaneous syndrome (CFCS) remain heterogeneous and almost without expert dermatological classification. OBJECTIVES To describe the dermatological manifestations of CFCS; to compare them with the literature findings; to assess those discriminating CFCS from other RASopathies, including Noonan syndrome (NS) and Costello syndrome (CS); and to test for dermatological phenotype-genotype correlations. METHODS We performed a 4-year, large, prospective, multicentric, collaborative dermatological and genetic study. RESULTS Forty-five patients were enrolled. Hair abnormalities were ubiquitous, including scarcity or absence of eyebrows and wavy or curly hair in 73% and 69% of patients, respectively. Keratosis pilaris (KP), ulerythema ophryogenes (UO), palmoplantar hyperkeratosis (PPHK) and multiple melanocytic naevi (MMN; over 50 naevi) were noted in 82%, 44%, 27% and 29% of patients, respectively. Scarcity or absence of eyebrows, association of UO and PPHK, diffuse KP and MMN best differentiated CFCS from NS and CS. Oral acitretin may be highly beneficial for therapeutic management of PPHK, whereas treatment of UO by topical sirolimus 1% failed. No significant dermatological phenotype-genotype correlation was determined. CONCLUSIONS A thorough knowledge of CFCS skin manifestations would help in making a positive diagnosis and differentiating CFCS from CS and NS.

Abstract
Pneumocystis pneumonia (PCP) is a life-threatening fungal disease that can occur in dogs. The aim of this study was to provide a preliminary genetic characterisation of Pneumocystis carinii f.sp.'canis' (P. canis) in dogs and thereby develop a reliable molecular protocol to definitively diagnose canine PCP. We investigated P. canis in a variety of lung specimens from dogs with confirmed or strongly suspected PCP (Group 1, n = 16), dogs with non-PCP lower respiratory tract problems (Group 2, n = 65) and dogs not suspected of having PCP or other lower respiratory diseases (Group 3, n = 11). Presence of Pneumocystis DNA was determined by nested PCR of the large and small mitochondrial subunit rRNA loci and by a real-time quantitative polymerase chain reaction (qPCR) assay developed using a new set of primers. Molecular results were correlated with the presence of Pneumocystis morphotypes detected in cytological/histological preparations. Pneumocystis DNA was amplified from 13/16 PCP-suspected dogs (Group 1) and from 4/76 dogs of control Groups 2 and 3 (combined). The latter four dogs were thought to have been colonized by P. canis. Comparison of CT values in 'infected' versus 'colonized' dogs was consistent with this notion, with a distinct difference in molecular burden between groups (CT ≤ 26 versus CT range (26 <CT < 35), respectively). Phylogenetic analyses showed that P. canis is specifically 'canine' associated, being separated from other mammalian Pneumocystis species, thereby confirming the accuracy of qPCR amplicon for Pneumocystis in dogs. Using qPCR, Pneumocystis DNA can be detected in specimens from the respiratory tract and a CT value can be interpreted to distinguish infection versus colonization.

Distinctive cutaneous and systemic features associated with specific antimyositis antibodies in adults with dermatomyositis: a prospective multicentric study of 117 patients. J Eur Acad Dermatol Venereol 2018; 32:1164-1172.

Abstract
BACKGROUND Identification of myositis-specific autoantibodies (MSAs) for dermatomyositis (DM) could allow the characterization of an antibody-associated clinical phenotype. OBJECTIVE We sought to define the clinical phenotype of DM and the risk of cancer, interstitial lung disease (ILD) and calcinosis based on MSA. METHODS A 3.5-year multicentre prospective study of adult DM patients was conducted to determine the clinical phenotype associated with MSAs and the presence of cancer, ILD and calcinosis. RESULTS MSAs were detected in 47.1% of 117 included patients. Patients with antimelanoma differentiation-associated protein-5 antibodies (13.7%) had significantly more palmar violaceous macules/papules [odds ratio (OR) 9.9], mechanic's hands (OR 8), cutaneous necrosis (OR 3.2), articular involvement (OR 15.2) and a higher risk of ILD (OR 25.3). Patients with antitranscriptional intermediary factor-1 antibodies (11.1%), antinuclear matrix protein-2 antibodies (6.8%) and antiaminoacyl-transfer RNA synthetase (5.1%) had, respectively, significantly more poikiloderma (OR 5.9), calcinosis (OR 9.8) and articular involvement (OR 15.2). Cutaneous necrosis was the only clinical manifestation significantly associated with cancer (OR 3.1). CONCLUSION Recognition of the adult DM phenotype associated with MSAs would allow more accurate appraisal of the risk of cancer, ILD and calcinosis.

Abstract
Current diagnosis of infectious diseases such as Hendra virus (HeV) relies mostly on laboratory-based tests. There is an urgent demand for rapid diagnosis technology to detect and identify these diseases in humans and animals so that disease spread can be controlled. In this study, an integrated lab-on-a-chip device using a magnetic nanoparticle immunoassay is developed. The key features of the device are the chaotic fluid mixing, achieved by magnetically driven motion of nanoparticles with the optimal mixing protocol developed using chaotic transport theory, and the automatic liquid handling system for loading reagents and samples. The device has been demonstrated to detect Hendra virus antibodies in dilute horse serum samples within a short time of 15 minutes and the limit of detection is about 0.48 ng ml-1. The device platform can potentially be used for field detection of viruses and other biological and chemical substances.

Nitric oxide is not obligatory for radial artery flow-mediated dilation following release of 5 or 10 min distal occlusion. Am J Physiol Heart Circ Physiol 2010; 298:H119-26.

Abstract
This study investigated the nitric oxide (NO) dependence of radial artery (RA) flow-mediated dilation (FMD) in response to three different reactive hyperemia (RH) shear stimulus profiles. Ten healthy males underwent the following three RH trials: 1) 5 min occlusion (5 trial), 2) 10 min occlusion (10 trial), and 3) 10 min occlusion with cuff reinflation at 30 s (10–30 trial). Trials were performed during saline infusion and repeated during NG-monomethyl-l-arginine (l-NMMA) infusion in the brachial artery. RA blood flow velocity was measured with Doppler ultrasound, and B-mode RA images were analyzed using automated edge detection software. Shear rate estimation of shear stress was calculated as the blood flow velocity/vessel diameter. l-NMMA decreased baseline vascular conductance by 35%. l-NMMA infusion did not affect the peak shear rate stimulus ( P = 0.681) or the area under the curve (AUC) of shear rate to peak FMD ( P = 0.088). The AUC was significantly larger in the 10 trial vs. the 10–30 or 5 trial ( P < 0.001). Although percent FMD (%change in diameter) in the 10 trial was larger than that in the 5 trial ( P = 0.035), there was no significant difference in %FMD between the saline and l-NMMA conditions in any trial: 5 trial, 5.62 ± 1.48 vs. 5.63 ± 1.27%; 10 trial, 9.07 ± 1.16 vs. 11.22 ± 2.21%; 10–30 trial, 6.52 ± 1.43 vs. 7.98 ± 1.51% for saline and l-NMMA, respectively ( P = 0.158). We conclude the following: 1) RH following 10 min of occlusion results in an enhanced stimulus and %FMD compared with 5 min of occlusion. 2) When the occlusion cuff is reinflated 30 s postrelease of a 10 min occlusion, it does not result in an enhanced %FMD compared with that which results from RH following 5 min of occlusion. 3) The lack of effect of l-NMMA on FMD suggests that NO may not be obligatory for radial artery FMD in response to either 5 or 10 min of occlusion in healthy volunteers.
