RESUMEN

Telemedicine in its most common form is the use of videoconferencing to consult with a patient and telapheresis is telemedicine in the form of videotelephony applied to consult with a patient for apheresis. The article discusses how a large apheresis program in a metropolitan area provided physician coverage for apheresis in a more remote hospital using telapheresis with local physician "partners" and local nurses employed by and trained by the apheresis program that perform the procedure. Consent for the procedure was obtained, and orders were placed by the local physician after consultation with the apheresis physician, or the apheresis physician him/herself, having obtained privileges at the remote hospital. This allowed patients access to apheresis procedures nearer to their place of residence and in familiar surroundings which generally made them feel more positive about their health care experience.

RESUMEN

The wide spread availability and use of sophisticated high-speed telecommunication networks coupled with inexpensive and easily accessible computing capacity have catalyzed the creation of new tools and strategies for healthcare delivery. Such tools and strategies are of value to apheresis medicine (AM) practitioners if they improve delivery of patient care, enhance safety during a therapeutic apheresis (TA) intervention, facilitate care access, advance technical capabilities of apheresis devices, and/or elevate quality performance within TA programs. In the past several years, healthcare delivery systems' adoption of telecommunication technologies has been fostered by organizational financial and quality improvement objectives. More recently, adoption of telehealth technologies has been catalyzed by the COVID-19 pandemic as these technologies enhance both patient and provider safety in an era of social distancing. These changes will also influence the delivery of TA services which now can be generally viewed in a tripartite model format comprised of traditional hospital-based fixed site locales, mobile TA operations and lately an evolving telemedicine remote management model now reffered to as telapheresis (TLA). This communication developed by the Public Affairs and Advocacy Committee of the American Society for Apheresis (ASFA) and endorsed by its Board of Directors, reviews and describes various aspects of established and evolving electronic technologies related to TLA and the practice of AM. In subsequent companion publications, additional aspects to TLA will be explored and ASFA's vision of reasonable, regulatory compliant and high-quality TLA practices will be expounded.

RESUMEN

INTRODUCTION: Limited evidence describes physical activity-associated bleeding risks for people with haemophilia, and risks are usually described only generically. AIM: To assess activity-specific ranges of risk for joint, soft tissue and head bleeds by identifying inherent and modifiable risk factors associated with each activity, based on opinions of expert physical therapists (PTs). METHODS: Physical therapists from US haemophilia treatment centres (HTCs) participated in a survey of 101 physical activities. For each activity, PTs provided minimum/maximum risk scores (low = 1; high = 5), and indicated specific bleeding risks in six joints and three injury types (bruising, muscle bleeding, head injury). Risk drivers were identified from free-text comments and explored at a consensus meeting, where they were categorized as inherent or modifiable and activity-driven or patient-driven. RESULTS: Of 32 invited PTs, 17 participated; median experience was 24 years as a PT and 16 years at an HTC. Only a few activities had a wide range of risk assessments encompassing both lower and upper ends of the response range. Joint injury risks were consistent with position and physical requirements, and head and muscle bleed risks were associated with physical contact. Eight PTs participated in the consensus meeting; key risk drivers identified included progression from seasonal to year-round participation, overtraining and improper body mechanics. Inherent risks included impact with surface/ball/equipment and field/surface condition; modifiable risks included safety equipment and tricks/stunts. CONCLUSIONS: These data provide a framework for discussion with patients/families, recognizing how certain activities may be modified to decrease risk, and identifying activities with nonmodifiable inherent risks.

RESUMEN

We previously localized and fine-mapped Charcot Marie Tooth 4A (CMT4A), the autosomal recessive, demyelinating peripheral neuropathy, to chromosome 8. Through additional positional cloning, we have identified a good candidate gene, encoding ganglioside-induced differentiation-associated protein-1 (GDAP1). We found three different mutations in four different Tunisian families-two nonsense and one missense mutation. How mutations in GDAP1 lead to CMT4A remains to be understood.

RESUMEN

CONTEXT: Considering that 42% of children and adolescents and 91% of dentate adults experience dental caries, oral disease is a public health problem. Although the population's oral health is improving, certain subgroups remain at increased risk for dental disease. OBJECTIVE: To assess the oral health status at the substate level and explore the possibility of geographic oral health inequalities in New Hampshire while building upon existing surveillance data sets. DESIGN: We used the Third Grade Oral Health and NH Behavioral Risk Factor Surveillance System surveys. We ensured the availability of substate level data and compared county/region specific estimates. SETTING: New Hampshire. PARTICIPANT: Adults and third-grade students in public schools. MAIN OUTCOME MEASURES: The prevalence of dental caries, untreated caries, and dental sealants among children; and the insurance status, utilization of dental services, and edentulism among adults. RESULTS: Of the 10 counties, the northernmost Coos County had consistently worse outcomes when compared with other counties. Only 64% of adult Coos County residents reported a dental visit in the past year; of these, 66% reported dental cleaning. Among adults 65 years and older, 29% were edentulous. In comparison with the state overall, these estimates were 76%, 77%, and 19%, respectively. Coos County third-grade students had the highest prevalence of dental caries experience (64% compared with 44% in New Hampshire) and untreated caries (31% compared with 12%), and only 24% had dental sealants (state prevalence is 60%). CONCLUSIONS: Overall oral health status in our state is favorable and comparable with the nation, yet significant geographic inequalities exist among children and adults. The oral health status of disparate groups can be improved using tailored interventions such as community water fluoridation or expansion of school-based dental sealant programs. Surveillance at the substate level is an essential part of the planning, targeting, and progress monitoring.

RESUMEN

There has long been informal debate among tissue viability nurse concerning the care mobile patients with venous leg ulcers recieve by GP practice nurses. There is anecdotal concern that evidence based care is not being given in some GP practices. This article considers the management of a patient with chronic venous leg ulceration. It highlights the importance of correct assessment, management and the application of evidence based practice. Suggestions are made for changing current leg ulcer service provision. It is hoped this article will stimulate debate on the national picture of leg ulcer service delivery.

RESUMEN

LC-MS4 has been used to detect and characterize in green coffee beans 12 chlorogenic acids not previously reported in nature. These comprise three isomeric dimethoxycinnamoylquinic acids (7-9) (Mr 382), three caffeoyl-dimethoxycinnamoylquinic acids (22, 24, and 26) (Mr 544), three diferuloylquinic acids (13-15) (Mr 544), and three feruloyl-dimethoxycinnamoylquinic acids (28, 30, and 32) (Mr 558). Structures have been assigned on the basis of LC-MS4 patterns of fragmentation and relative hydrophobicity and, in the case of the dimethoxycinnamoylquinic acids, by comparison with authentic standards. Several new structure-diagnostic fragmentations have been identified for use with diacyl-chlorogenic acids, for example, m/z 299 and 255 for C4 caffeoyl, m/z 313 and 269 for C4 feruloyl, nearly equal elimination of both cinnamoyl residues for vic-3,4-diacyl, and an increasing ratio of "dehydrated" ions to "non-dehydrated" ions at MS2 with increasing methylation of those cinnamoyl residues. Possible mechanisms have been proposed to account for the fragmentations observed. The mass spectrometric resolution of six isomeric chlorogenic acids (Mr 544) in a crude plant extract by fragment-targeted LC-MS2 and LC-MS3 experiments illustrates the analytical power and advantage of ion trap mass spectroscopy.

RESUMEN

LC-MS4 has been used to detect and characterize in green coffee beans 15 quantitatively minor p-coumaric acid-containing chlorogenic acids not previously reported in nature. These comprise 3,4-di-p-coumaroylquinic acid, 3,5-di-p-coumaroylquinic acid, and 4,5-di-p-coumaroylquinic acid (Mr 484); 3-p-coumaroyl-4-caffeoylquinic acid, 3-p-coumaroyl-5-caffeoylquinic acid, 4-p-coumaroyl-5-caffeoylquinic acid, 3-caffeoyl-4-p-coumaroyl-quinic acid, 3-caffeoyl-5-p-coumaroyl-quinic acid; and 4-caffeoyl-5-p-coumaroyl-quinic acid (Mr 500); 3-p-coumaroyl-4-feruloylquinic acid, 3-p-coumaroyl-5-feruloylquinic acid and 4-p-coumaroyl-5-feruloylquinic acid (Mr 514); and 4-dimethoxycinnamoyl-5-p-coumaroylquinic acid and two isomers (Mr 528) for which identities could not be assigned unequivocally. Structures have been assigned on the basis of LC-MS4 patterns of fragmentation. Forty-five chlorogenic acids have now been characterized in green Robusta coffee beans.

RESUMEN

The fragmentation behavior of all six dicaffeoylquinic acids (diCQA) has been investigated using LC-MS(4). It is possible to discriminate between each of the isomers including those for which commercial standards are not available. For diCQA, the ease of removal of the caffeoyl residue during fragmentation is 1 approximately = 5 > 3 > 4. The distinctive fragmentation observed for the little-studied 1,4-dicaffeoylquinic acid involves elimination of the C1 caffeoyl residue, repeated dehydrations leading to the aromatization of the quinic acid moiety, and its decarboxylation. It is suggested that this process is initiated by the C1 carboxyl protonating the C5 hydroxyl in the inverted chair conformer, followed by its protonating the C1 caffeoyl residue in the favored chair conformation. The fragmentation of 1-caffeoylquinic acid is indistinguishable from that of the commercially available 5-caffeoylquinic acid, but these two isomers can be distinguished easily by their facile chromatographic resolution on reversed phase packings. The hierarchical key previously developed for characterizing chlorogenic acids has been extended to accommodate 1-caffeoylquinic acid and the 1-acyl dicaffeoylquinic acids.

RESUMEN

Carnivorous plants are usually restricted to nutrient-poor environments, suggesting that there is a cost to caputuring animals that is offset by the benefits of carnivory only under unusual circumstances. One such cost could involve a reduced photosynthetic capacity associated with the growth and maintenance of prey-capture organs. This hypothesis is tested using the common bladderwort, Utricularia macrohiza, which bears numerous distinct prey-capture bladders. Measurements of the photosynthetic and respiration rates of leaves and bladders were incorporated into growth models to estimate the growth rates of plants with and without bladders. Comparisons were made in three lakes which differed in nutrient status and in which plants exhibited marked differences in their densities of prey-capture bladders. Overall, photosynthetic rates for leaves were approximately twice those for bladders while respiration rates did not differ significantly between tissues. Calculations incorporating these values indicate that plants producing both bladders and leaves would grow to as little as 21% or as much as 83% of plants that produced leaves alone. Comparisons among lakes led to the rejection of the hypothesis that plants from some lakes are able to produce more bladders per leaf because bladders differ in their photosynthetic productivity.

RESUMEN

The fragmentation behavior of 18 chlorogenic acids that are not substituted at position 1 has been investigated using LC-MS(4) applied to a methanolic coffee bean extract and commercial cider (hard cider). Using LC-MS(3), it is possible to discriminate between each of the three isomers of p-coumaroylquinic acid, caffeoylquinic acid, feruloylquinic acid, and dicaffeoylquinic acid, and a hierarchical key has been prepared to facilitate this process when standards are not available. MS(4) fragmentations further support these assignments, but were not essential in reaching them. The distinctive behavior of 4-acyl and 3-acyl chlorogenic acids compared with the 5-acyl chlorogenic acids is a key factor permitting these assignments. The fragmentation patterns are dependent upon the particular stereochemical relationships between the individual substituents on the quinic acid moiety. Fragmentation is facilitated by 1,2-acyl participation and proceeds through quinic acid conformers in which the relevant substituents transiently adopt a 1,3-syn-diaxial relationship. Selected ion monitoring at m/z 529 clearly indicated the presence in coffee of six caffeoylferuloylquinic acid isomers, whereas previously only two or three had been demonstrated. The hierarchical key permitted specific structures to be assigned to each of the six isomers. These assignments are internally consistent and consistent with the limited data previously available.

RESUMEN

OBJECTIVE: Nonmedically indicated (elective) deliveries before 39 weeks of gestation result in unnecessary neonatal morbidity. We sought to determine whether implementation of a process improvement program will decrease the rate of elective scheduled singleton early-term deliveries (37 0/7-38 6/7 weeks of gestation) in a group of diverse community and academic hospitals. METHODS: Policies and procedures for scheduling inductions and cesarean deliveries were implemented and patient and health care provider education was provided. Outcomes for scheduled singleton deliveries at 34 weeks of gestation or higher were submitted through a web-based data entry system. The rate of scheduled singleton elective early-term deliveries as well as the rates of early-term medically indicated and unscheduled deliveries, neonatal intensive care unit admissions, and singleton term fetal mortality rate were evaluated. RESULTS: A total of 29,030 scheduled singletons at 34 weeks of gestation or higher were delivered in 26 participating hospitals between January 2011 and December 2011. Elective scheduled early-term deliveries decreased from 27.8% in the first month to 4.8% in the 12th month (P<.001); rates of elective scheduled singleton early-term inductions (72%, P=.029) and cesarean deliveries (84%; P<.001) decreased significantly. There was no change in medically indicated or unscheduled early-term deliveries. Neonatal intensive care unit admissions among scheduled early-term singletons decreased nonsignificantly from 1.5% to 1.2% (P=.24). There was no increase in the term fetal mortality rate. CONCLUSION: A rapid-cycle process improvement program substantially decreased elective scheduled early-term deliveries to less than 5% in a group of diverse hospitals across multiple states. LEVEL OF EVIDENCE: III.

RESUMEN

OBJECTIVE: Patients with rheumatoid arthritis (RA) with lower socioeconomic status (SES) are known to have more severe disease, more comorbidity, and higher mortality. It is not known whether SES influences response to treatment in RA. We examined the relationship between area of residence (as a surrogate for SES) and baseline outcome measures and response to treatment, using data from the British Rheumatoid Outcome Study Group randomized controlled trial of aggressive versus symptomatic treatment of long-standing, stable RA. METHODS: A total of 466 patients from 5 centers were recruited to the trial. Baseline data included age, sex, smoking status, and comorbidity. Patients were assigned a Townsend score (a measure of social deprivation) according to their area of residence. Outcome measures including the Disease Activity Score (DAS28), Health Assessment Questionnaire, Medical Outcomes Study Short Form-36, and EuroQol (EQ5D) were recorded at the beginning and end of the 3 year trial. The baseline, 3 year values, and change data were examined by Townsend quintile adjusting for each treatment arm. RESULTS: Significant relationships between increasing social deprivation by area of residence and higher disease activity, higher pain, poorer physical function, poorer emotional aspects of mental health, and lower quality of life were found at baseline (adjusted for age, sex, disease duration, current smoking, treatment center, and treatment group). During the 3 year trial period, patients from the most deprived areas showed greater improvement, with statistically significant greater improvement on DAS28 (p = 0.041) and 28 tender joint count (p = 0.015). CONCLUSION: Area of residence is related to the severity of RA at recruitment and is a predictor of response in a clinical trial situation. The results suggest that measures of SES should be recorded for patients enrolled in clinical trials, longitudinal observational studies, and in the clinical setting.
