RESUMEN

Death Cafes (DCs) explicitly encourage conversation and constitute space to explore the dialogue around death and dying. This study draws on scholarship from communication and dialogue theory to explore the design features and facilitation practices used within DC meetings. Through qualitative analysis of the DC webpage and interviews with facilitators, the study uncovers how DC facilitators structure and manage conversations to help attendees normalize death conversations and manage the death anxiety of others in their lives. The analysis highlights three main tensions within the DC structure and facilitation guidelines: structure versus openness, authority versus equality, and conversation versus information. These fundamental contradictions are inherent in DCs, and facilitators need to manage them in order to promote meaningful dialogue among DC participants. This study deepens the theorizing around DC facilitation practices and has implications for death and dying practitioners hoping to foster dialogue about end-of-life topics.

RESUMEN

This article draws on the deliberative play framework to examine empirical examples of storytelling in an online deliberative forum: The Oregon Citizen Assembly (ORCA) Pilot on COVID-19 Recovery. ORCA engaged 36 citizens in deliberation about state policy through an online deliberative process spanning seven weeks. Drawing on literature on small stories in deliberation, we trace stories related to a policy proposal about paying parents to educate children at home. Our analysis demonstrates that storytelling activities accomplish aspects of deliberative play through introducing uncertainty, resisting premature closure, and promoting an "as if" frame that allows groups to explore the scope and implications of proposals. Forum design influences interaction and our analysis suggests that technology use and timing are key design features that can facilitate or inhibit deliberative play.

RESUMEN

In this article, we demonstrate the method of participatory causal modeling to map the interdependencies of critical performance variables in a complex nonprofit health care provider with considerable financial and operational control challenges. Critical performance variables are output performance dimensions that are fundamental indicators of organizational success. Causal modeling provides an approach for nonprofit leaders to examine how critical performance variables dynamically and recursively affect each other and thereby offers a path to identify key points of leverage for organizational action. Using a case study, we show that participatory system dynamics modeling revealed assumptions, choices, and complexities and so helped a nonprofit health care organization recognize possible strategic opportunities. This study demonstrates an approach that other nonprofits may deploy in situations where they are experiencing competing objectives and constraints in managing critical performance variables.

RESUMEN

A 15-year-old female blue and gold macaw ( Ara ararauna) was presented for evaluation after being found laterally recumbent, reluctant to move, and lethargic. Results of a complete blood count showed an increased number of immature heterophils with increased cytoplasmic basophilia and degranulation and the presence of a left shift. Radiographs and a computed tomography scan were performed and revealed a markedly enlarged spleen. An ultrasound-guided fine-needle aspirate of the spleen was submitted for cytologic examination and aerobic bacterial culture. While the culture revealed no growth, cytologic examination identified mononuclear phagocytes with cytoplasmic vacuoles containing structures consistent with bacteria. Pan-bacterial 16S rRNA polymerase chain reaction of the splenic sample followed by direct sequencing identified a Coxiella-like agent identical to one previously isolated in the liver of a golden-mantled rosella ( Platycercus eximius). Phylogenetic analysis shows that avian coxiellosis agents and Coxiella burnetii, the agent of Q fever, represent 2 independent events of development of vertebrate pathogenicity in this group of tick endosymbionts. This report suggests diagnostic and treatment directions for coxiellosis in avian patients and indicates where further study is needed.

RESUMEN

Many public and private genome-wide association studies that we have analyzed include flaws in design, with avoidable confounding appearing as a norm rather than the exception. Rather than recognizing flawed research design and addressing that, a category of quality-control statistical methods has arisen to treat only the symptoms. Reflecting more deeply, we examine elements of current genomic research in light of the traditional scientific method and find that hypotheses are often detached from data collection, experimental design, and causal theories. Association studies independent of causal theories, along with multiple testing errors, too often drive health care and public policy decisions. In an era of large-scale biological research, we ask questions about the role of statistical analyses in advancing coherent theories of diseases and their mechanisms. We advocate for reinterpretation of the scientific method in the context of large-scale data analysis opportunities and for renewed appreciation of falsifiable hypotheses, so that we can learn more from our best mistakes.

RESUMEN

In this paper we describe the validation of two scales constructed to measure pre-university students' changing disposition (i) to enter Higher Education (HE) and (ii) to further study mathematically-demanding subjects. Items were selected drawing on interview data, and on a model of disposition as socially- as well as self- attributed. Rasch analyses showed that the two scales each produce robust one-dimensional measures on what we call a 'strength of commitment to enter HE' and 'disposition to study mathematically-demanding subjects further' respectively. However, the former scale was initially found to suffer psychometrically from a ceiling effect, which we 'corrected' by adding some harder items at a later data point, and revised the scale according to our interpretation of subsequent results. We finally discuss the potential significance of the constructed measures of learning outcomes, as variables in monitoring or even explaining students' progress into different subjects in HE.

RESUMEN

PURPOSE: Vorapaxar is an orally active protease-activated receptor 1 (PAR-1) antagonist that inhibits thrombin-induced platelet aggregation. This open-label study assessed the pharmacokinetics and pharmacodynamics of single-dose warfarin in the presence/absence of multiple-dose vorapaxar in 12 healthy men. METHODS: Subjects received two treatments separated by ≥ 7-day washout: Treatment A warfarin 25 mg (Day 1); Treatment B vorapaxar 2.5 mg/day on Days 1-6 and vorapaxar 40 mg coadministered with warfarin 25 mg (Day 7). R-warfarin, S-warfarin, and prothrombin time (PT) were assayed predose and up to 120 h postdose. RESULTS: The geometric mean ratio (GMR) as a percentage (warfarin + vorapaxar/warfarin) was calculated. The GMR (90 % CIs) estimates of C(max) were 105 (99, 111) and 105 (99, 112) for R- and S-warfarin, respectively. The GMR (90 % CIs) estimates of AUC(0-∞) were 108 (101, 116) and 105 (96, 115) for R- and S-warfarin, respectively. The GMR (95 % CIs) estimates of AUC(0-120 h) for PT and INR were 97 (95, 98) and 96 (94, 98), respectively. CONCLUSION: Results of this study indicate that vorapaxar has no meaningful effect on the pharmacokinetics or pharmacodynamics of warfarin, suggesting that the coadministration of these two drugs or vorapaxar coadministered with other CYP2C9/CYP2C19 substrates is unlikely to cause a clinically significant pharmacokinetic drug interaction.

RESUMEN

This qualitative study evaluated barriers and facilitators to mobility in the homes of children with medical complexity (CMC) and the subsequent impact on CMC and their families. Eighteen caregivers of CMC were interviewed. Parents described that accessibility barriers impaired delivery of care at home and impacted the child's participation in family life. The most inaccessible areas were stairs and bathrooms. Mobility and transfers became more difficult as children grew larger. Parents and children sustained injuries from performance of activities of daily living (ADLs). When available, durable medical equipment (DME) and home modifications improved home access and typically were funded using insurance and state Title V funds. However, parents reported that larger home modifications, such as bathroom modifications, were cost prohibitive. A pediatrician's inquiry about mobility barriers may reveal crucial information about delivery of home care to CMC. CMC may be referred to rehabilitation specialists to address mobility needs.

RESUMEN

INTRODUCTION: We sought to characterize the current supports used by parents to care for children with medical complexity (CMC) at home and parental preferences for additional supports to meet identified gaps. METHOD: Semistructured interviews were conducted with parents of 18 CMC. Interviews were transcribed then analyzed using a constant comparative approach. RESULTS: Extended family and community offloaded nonmedical tasks, assisted financially, gave emotional reinforcement, and cared for CMC. Home health providers also directly cared for CMC, but access and quality varied. Government programs paid for in-home care, but eligibility varied. Parents wanted more paid home care but also more support completing nonmedical tasks, mitigating financial strains, and accessing mental health services. DISCUSSION: Parents of CMC relied on family and community members to help fill existing gaps in-home care, but gaps remained, suggesting the need for more medical and social supports for the in-home care of CMC and their families.

RESUMEN

A neutered male Mexican Hairless dog was presented for generalized weight loss and weakness. Initial laboratory testing and diagnostic imaging revealed thrombocytopenia and an interstitial to miliary lung pattern affecting all lung fields. Mild joint effusion was found on physical examination affecting the stifle, tarsal, carpal, and elbow joints. Examination of synovial fluid demonstrated an inflammatory polyarthropathy in 3 joints. Cytocentrifuged and direct preparations of the bronchoalveolar lavage (BAL) fluid sample were made and cells consistent with lupus erythematosus (LE) cells and ragocytes were found. Based on these findings, the anti-nuclear antibody (ANA) titer was determined as 1:640. A clinical diagnosis of systemic LE was made based on the satisfaction of 2 major criteria (thrombocytopenia and inflammatory polyarthritis), 4 minor criteria (central nervous system signs, lymphadenopathy, fever of unknown origin, and pleuritis), positive ANA titer, and the identification of presumed LE cells in BAL fluid. This case report highlights a novel finding of LE cells in respiratory secretions and provides a review of diagnostic criteria of systemic LE.

RESUMEN

Inhalant abuse is the intentional inhalation of a volatile substance for the purpose of achieving an altered mental state. As an important, yet underrecognized form of substance abuse, inhalant abuse crosses all demographic, ethnic, and socioeconomic boundaries, causing significant morbidity and mortality in school-aged and older children. This review presents current perspectives on epidemiology, detection, and clinical challenges of inhalant abuse and offers advice regarding the medical and mental health providers' roles in the prevention and management of this substance abuse problem. Also discussed is the misuse of a specific "over-the-counter" dissociative, dextromethorphan.

RESUMEN

Alitretinoin (9-cis-retinoic acid) is an FDA-approved topical therapy for the treatment of Kaposi sarcoma. Alitretinoin is a naturally occurring endogenous retinoid that binds to and activates all known intracellular retinoic acid receptor (RAR) subtypes alpha, beta, and gamma and retinoic X receptor (RXR) subtypes alpha, beta, and gamma. Photoaging of the skin is the result of accumulated exposure to solar UV radiation. Several topically applied retinoids have been proven clinically effective for treating the appearance of photoaging. Tretinoin and tazarotene, which have been shown to improve photodamaged skin, bind RAR subtypes only. The theoretic benefit of alitretinoin gel 0.1% (Panretin) in the treatment of photoaged skin stems from the binding and activation of both RARs and RXRs, which promote the repair mechanisms in damaged skin. The objective of this study was to evaluate the safety and efficacy of topical alitretinoin gel 0.1% in the treatment of photodamaged skin. The treatment was well tolerated by participants (N=20) and subjectively showed improvement of benign skin lesions (eg, seborrheic keratoses) and precancerous lesions (eg, actinic keratoses). Larger, blinded, controlled trials are needed to investigate the role of this novel retinoid in the treatment of photoaging.

RESUMEN

This ex vivo human percutaneous absorption study evaluated a set of six model drugs (ketamine hydrochloride, bupivacaine hydrochloride, diclofenac sodium, gabapentin, orphenadrine citrate, pentoxifylline) from two popular formulations for topically applied compounding preparations. The compounded preparations used in this study were Versatile cream and a reference cream. Each formulation was applied to human trunk skin mounted on Franz Diffusion Cells, 50 mg/chamber (or 28.2 mg/cm2). Serial dermal receiver solutions were collected for 48 hours. Analysis of the resultant data supports the concept that the Versatile base formulation provides improved characteristics relative to the reference base. This is of key importance where the patient does not show clinical improvement when a conventional topical delivery vehicle is used in the formulation. From the results, it is reasonable to anticipate that, relative to the reference formulation, the Versatile formulation provides enhanced transdermal delivery of some analgesic medications.

RESUMEN

La biomedicina en su rama de genética, ha experimentado grandes progresos científicos y técnicos en los últimos años, especialmente a partir del descubrimiento del genoma humano. Los avances originados han sobrepasado el ámbito de la patología para continuar los estudios en materia de salud, donde se incluyen las investigaciones de actividad física y deporte. Los atletas cuyo objetivo es conseguir el máximo rendimiento, pueden valerse de esta herramienta ilegal de células genéticamente modificadas. El abuso de conocimientos y técnicas adquiridos en el área de la terapia génica es una forma de dopaje, y está prohibido. Hasta el momento no hay pruebas de que ese dopaje genético se haya practicado aunque es probable su uso en un breve periodo de tiempo. En el presente trabajo de revisión se abordan los aspectos relacionados con la manipulación genética en el rendimiento deportivo y especialmente los genes que tienen un efecto directo sobre el comportamiento muscular. Pretendemos dar a conocer la realidad actual, además de identificar y analizar las proteínas más relevantes basadas en el dopaje genético

The advances added have surpassed the scope of the pathology to continue the studies in the field of health, which includes the investigations of physical activity and sport. Athletes, whose goal is to achieve maximum performance, can use this banned tool of genetically modified cells. Abuse of knowledge and techniques acquired in the field of gene therapy is a form of doping, and is prohibited. So far there is no evidence that this genetic doping has been practiced although it is likely to be used in a short period of time. In the present revision are analyzed the aspects related to the genetic manipulation in the sport performance and especially the genes that have a direct effect on the muscular behavior. We like to done more information about the current reality, and identify and analyze the most relevant proteins based on genetic doping

RESUMEN

BACKGROUND: Botulinum toxin type B (BTX-B, Myobloc, San Francisco, CA, USA) was FDA-approved for the treatment of cervical dystonia in December 2000. It has since been used off-label for the treatment of axillary hyperhidrosis. However, there are sparse data in the medical literature evaluating the safety and efficacy of Myobloc (botulinum toxin type B) for this indication. OBJECTIVE: To assess the safety, efficacy and duration of action of Myobloc (botulinum toxin type B) in the treatment of bilateral axillary hyperhidrosis. METHODS: This study was a double-blinded, randomized, pilot study conducted in an outpatient office setting at a private academic medical center beginning in November 2001. Twenty-three male and female volunteers between the ages of 18 and 80 were screened for participation; 20 participants with primary axillary hyperhidrosis were enrolled. Participants were injected subcutaneously with either Myobloc (botulinum toxin type B) (2500 U, or 0.5 ml, per axilla) or 0.5 ml vehicle (100 mM NaCl, 10 mM succinate, and 0.5 mg/ml human albumin) into bilateral axillae. Participants who received placebo were rolled over and received Myobloc (botulinum toxin type B) at subsequent visits. All participants were followed until sweating returned to baseline levels. This trial was initially conceived as a placebo-controlled study; however, owing to the insufficient size of the placebo group, the placebo arm of this trial was dropped during data analysis. The main outcome measures were safety, efficacy, and duration of effect. RESULTS: According to participant assessment of axillary hyperhidrosis improvement (A-HI) and quality of life (A-HQOL) scores and the physician assessment scores, a significant difference was observed in treatment response at Day 30 in the participants receiving Myobloc (botulinum toxin type B) injections. Duration of action ranged from 2.2 to 8.1 months (mean 5.0 months). The adverse event profile included bruising, flu-like symptoms, and dry eyes. CONCLUSION: Myobloc (botulinum toxin type B) proved to be safe and efficacious for the treatment of bilateral axillary hyperhidrosis. More studies are needed to assess the duration of response using different doses of Myobloc (botulinum toxin type B).
