Nursing intervention versus usual care to improve delirium among home-dwelling older adults receiving homecare after hospitalization: feasibility and acceptability of a Randomized Controlled Trail.

BACKGROUND: Delirium is an acute cognitive impairment among older hospitalized patients. It can persist until discharge and for months after that. Despite proof that evidence-based nursing interventions are effective in preventing delirium in acute hospitals, interventions among home-dwelling older patients is lacking. The aim was to assess feasibility and acceptability of a nursing intervention designed to detect and reduce delirium in older adults after discharge from hospital. METHODS: Randomized clinical pilot trial with a before/after design was used. One hundred and three older adults were recruited in a home healthcare service in French-speaking Switzerland and randomized into an experimental group (EG, n = 51) and a control group (CG, n = 52). The CG received usual homecare. The EG received usual homecare plus five additional nursing interventions at 48 and 72 h and at 7, 14 and 21 days after discharge. These interventions were tailored for detecting and reducing delirium and were conducted by a geriatric clinical nurse (GCN). All patients were monitored at the start of the study (M1) and throughout the month for symptoms of delirium (M2). This was documented in patients' records after usual homecare using the Confusion Assessment Method (CAM). At one month (M2), symptoms of delirium were measured using the CAM, cognitive status was measured using the Mini-Mental State Examination (MMSE), and functional status was measured using Katz and Lawton Index of activities of daily living (ADL/IADL). At the end of the study, participants in the EG and homecare nurses were interviewed about the acceptability of the nursing interventions and the study itself. RESULTS: Feasibility and acceptability indicators reported excellent results. Recruitment, retention, randomization, and other procedures were efficient, although some potentially issues were identified. Participants and nurses considered organizational procedures, data collection, intervention content, the dose-effect of the interventions, and methodology all to be feasible. Duration, patient adherence and fidelity were judged acceptable. Nurses, participants and informal caregivers were satisfied with the relevance and safety of the interventions. CONCLUSIONS: Nursing interventions to detect/improve delirium at home are feasible and acceptable. These results confirm that developing a large-scale randomized controlled trial would be appropriate. TRIAL REGESTRATION: ISRCTN registry no: 16103589 - 19 February 2016.

Degree of hermeticity of a multicompartment compliance aid: Implications for the quality of professional pharmaceutical services

A multicompartment compliance aid (MCA) is a blister-type repackaging system that aims to facilitate drug administration and thereby increase patient adherence. One of the characteristics of the MCA that should be taken into account is the moisture permeability, since this atmospheric condition is one of the most important factors that can modify the stability of medicines. In the current paper we report the moisture permeability tests performed on a MCA according to the US Pharmacopeia. This information on the suitability of the device will help pharmacists implement a high-quality professional service.

Évaluation d’une intervention infirmière Motivationnelle Selon les Stades de Changement (MSSC) sur des comportements d’auto-soins chez des patients insuffisants cardiaques

L’insuffisance cardiaque (IC), une maladie chronique caractérisée par un mauvais fonctionnement du muscle cardiaque, entraîne des symptômes comme l’essoufflement, l’œdème et la fatigue. L’IC nécessite l’adoption de comportements d’auto-soins pour prévenir les épisodes de décompensation. Le but de cette recherche est d’évaluer l’intervention infirmière motivationnelle selon les stades de changements (MSSC) sur les comportements d’auto-soins chez des patients IC. Afin de guider l’intervention MSSC, la théorie spécifique aux auto-soins chez les patients IC de Riegel et Dickson (2008) a été retenue ainsi que le modèle d’intervention de Bédard et al. (2006) combinant le modèle transthéorique (Prochaska & DiClemente, 1984) et l’entrevue motivationnelle (Miller & Rollnick, 2006). Il s’agit d’un devis expérimental randomisé (pré et post-test) avec groupe contrôle (N = 15/groupe). Les patients du groupe contrôle ont reçu les soins usuels et les patients du groupe intervention (GI) ont reçu l’intervention MSSC durant trois entretiens. Les mesures de résultats ont été collectées à un mois suite à la randomisation par une assistante de recherche aveugle à la randomisation. L’effet de l’intervention a été évalué par des analyses de covariance sur cinq mesures de résultats : la réalisation et la gestion (générale et spécifique à l’IC) des auto-soins, la confiance aux auto-soins (générale et spécifique à l’IC) et la conviction. L’acceptabilité et la faisabilité ont été évaluées. Les résultats indiquent un effet significatif sur la mesure de confiance à effectuer les auto-soins spécifiques à l’IC. La majorité des participants du GI ont progressé dans leurs stades de changement. Ces résultats soulignent le potentiel de cette approche pour favoriser l’adoption des auto-soins mais une étude à plus large échelle est proposée afin d’évaluer l’effet de cette approche dans un essai clinique randomisé.

Compliance measurement-guided medication management programs in hypertension : a systematic review

Objectif principal: Il n’est pas démontré que les interventions visant à maîtriser voire modérer la médicamentation de patients atteints d’hypertension peuvent améliorer leur gestion de la maladie. Cette revue systématique propose d’évaluer les programmes de gestion contrôlée de la médicamentation pour l’hypertension, en s’appuyant sur la mesure de l’observance des traitements par les patients (CMGM). Design: Revue systématique. Sources de données: MEDLINE, EMBASE, CENTRAL, résumés de conférences internationales sur l’hypertension et bibliographies des articles pertinents. Méthodes: Des essais contrôlés randomisés (ECR) et des études observationnelles (EO) ont été évalués par 2 réviseurs indépendants. L’évaluation de la qualité (de ce matériel) a été réalisée avec l’aide de l’outil de Cochrane de mesure du risque de biais, et a été estimée selon une échelle à quatre niveaux de qualité Une synthèse narrative des données a été effectuée en raison de l'hétérogénéité importante des études. Résultats: 13 études (8 ECR, 5 EO) de 2150 patients hypertendus ont été prises en compte. Parmi elles, 5 études de CMGM avec l’utilisation de dispositifs électroniques comme seule intervention ont relevé une diminution de la tension artérielle (TA), qui pourrait cependant être expliquée par les biais de mesure. L’amélioration à court terme de la TA sous CMGM dans les interventions complexes a été révélée dans 4 études à qualité faible ou modérée. Dans 4 autres études sur les soins intégrés de qualité supérieure, il n'a pas été possible de distinguer l'impact de la composante CMGM, celle-ci pouvant être compromise par des traitements médicamenteux. L’ensemble des études semble par ailleurs montrer qu’un feed-back régulier au médecin traitant peut être un élément essentiel d’efficacité des traitements CMGM, et peut être facilement assuré par une infirmière ou un pharmacien, grâce à des outils de communication appropriés. Conclusions: Aucune preuve convaincante de l'efficacité des traitements CMGM comme technologie de la santé n’a été établie en raison de designs non-optimaux des études identifiées et des ualités méthodologiques insatisfaisantes de celles-ci. Les recherches futures devraient : suivre les normes de qualité approuvées et les recommandations cliniques actuelles pour le traitement de l'hypertension, inclure des groupes spécifiques de patients avec des problèmes d’attachement aux traitements, et considérer les résultats cliniques et économiques de l'organisation de soins ainsi que les observations rapportées par les patients.

Prevalencia y factores asociados a la no adherencia al tratamiento farmacológico con antipsicóticos en pacientes adultos con esquizofrenia

Objetivo: Determinar la prevalencia y los factores asociados a la no adherencia al tratamiento farmacológico con antipsicóticos en pacientes adultos con esquizofrenia. Métodos: Estudio de corte transversal de 184 pacientes en la Clínica La Paz, en Bogotá entre el período de 2008 – 2009. Se hizo recolección y verificación de la información con la aplicación de un cuestionario que evaluó factores relacionados con la no adherencia terapéutica. Resultados: La prevalencia de no adherencia fue del 51.2%. Las variables con asociación estadísticamente significativa a la no adherencia al tratamiento farmacológico fueron: pertenecer a los estratos socioeconómicos bajos (RP=1.35; IC 95% 1.01 - 1.79), tener un nivel educativo de primaria (RP= 1.44; IC 95%: 1.07 - 1.93), consumo de sustancias psicoactivas, marihuana (RP=1.80, IC95%: 1.40 – 2.32), tener familiares de primer grado con antecedentes de enfermedad mental (RP=1.48, IC95%: 1.12 -1.94); y el tener madre con antecedente de enfermedad mental (RP=1.77, IC95%: 1.36 - 2.31). Los factores que explicaron la no adherencia con el análisis multivariado fueron: el no haber tenido a tiempo los medicamentos y el no haberlos recibido en su totalidad en el último mes, comportándose como factores con mayor probabilidad de asociación a la no adherencia. Conclusión: Tener antecedentes familiares en primer grado de enfermedad mental, inadecuado acceso a los servicios de salud, consumo de sustancias psicoactivas y efectos adversos aumentan el riesgo de no adherencia al tratamiento farmacológico en pacientes esquizofrénicos predisponen a un mayor riesgo de no adherencia terapéutica. Palabras clave: Esquizofrenia, adherencia al tratamiento, factores de riesgo, antipsicóticos.

Causes of preventable drug-related hospital admissions: a qualitative study

Objective: To explore the causes of preventable drug-related admissions (PDRAs) to hospital. Design: Qualitative case studies using semi-structured interviews and medical record review; data analysed using a framework derived from Reason's model of organisational accidents and cascade analysis. Participants: 62 participants, including 18 patients, 8 informal carers, 17 general practitioners, 12 community pharmacists, 3 practice nurses and 4 other members of healthcare staff, involved in events leading up to the patients' hospital admissions. Setting: Nottingham, UK. Results: PDRAs are associated with problems at multiple stages in the medication use process, including prescribing, dispensing, administration, monitoring and help seeking. The main causes of these problems are communication failures ( between patients and healthcare professionals and different groups of healthcare professionals) and knowledge gaps ( about drugs and patients' medical and medication histories). The causes of PDRAs are similar irrespective of whether the hospital admission is associated with a prescribing, monitoring or patient adherence problem. Conclusions: The causes of PDRAs are multifaceted and complex. Technical solutions to PDRAs will need to take account of this complexity and are unlikely to be sufficient on their own. Interventions targeting the human causes of PDRAs are also necessary - for example, improving methods of communication.

Implante endoscópico no esôfago distal de polimetilmetacrilato para controle do refluxo gastrofágico : estudo experimental em modelo animal

XIXA doença do refluxo gastroesofágico (DRGE) comumente afeta o esôfago e provavelmente é a condição mais prevalente no segmento alto do trato gastrointestinal, acometendo entre 5 e 45% da população ocidental. A terapêutica atual para essa doença além de medidas gerais e dietéticas, inclui tratamento farmacológico e/ou cirurgia. Ambos podem ser eficazes, mas apresentam elevado custo financeiro. O tratamento com fármacos pode apresentar baixa aderência medicamentosa e a cirurgia tem baixa, mas não desprezível, morbidade e mortalidade. Idealmente o tratamento da DRGE deveria ser eficaz, com baixo risco e com baixo custo. Objetivos: 1. Desenvolver um modelo experimental em suínos para o estudo do Refluxo Gastroesofágico através da Pressão e do Volume de Vazão Gástricos; 2. Avaliar a eficácia do implante endoscópico de PMMA ao nível do Esfíncter Esofágico Inferior (EEI) para aumentar a Pressão de Vazão Gástrica, o Volume de Vazão Gástrico e a Pressão Basal do EEI; 3. Descrever as reações histológicas associadas ao implante de PMMA. Material e Métodos: Suínos da raça Large White, do sexo feminino com 8 semanas de vida foram estudados no experimento. Foi realizada manometria do esfíncter esofágico inferior com registro da pressão basal com cateter de perfusão com água e técnica de retirada lenta. Calculou-se, também, a extensão do EEI. Após, gastrostomia era realizada com colocação intragástrica da extremidade distal de uma sonda de Foley com três vias e um cateter de pHmetria esofágica introduzido via oral com o sensor distal posicionado 5 cm acima do bordo superior de esfíncter esofágico inferior. Iniciava-se, XXentão, a infusão contínua no estômago de uma solução de HCl a 0,02N com medida e registro simultâneos da Pressão e do Volume de Vazão Gástricos e do pH esofágico. Definiu-se a Pressão de Vazão Gástrica (PVG) e o Volume de Vazão Gástrico quando houve brusca e sustentada acidificação do esôfago distal (pH<3). Após, introduzia-se um tubo metálico (Tubo Introdutor ou TI) via oral e, em seguida, o endoscópio, seguindo ambos até o esôfago distal. Cateter de nylon com agulha calibre 16 era introduzido pelo tubo introdutor e o PMMA implantado na área correspondente ao EEI com uma pistola dosadora volumétrica que permitia a injeção de volumes prédeterminados em 3 ou 4 pontos da submucosa (total por ponto = 0,73 ml de PMMA). As medidas de PVG, VVG e pressão basal do EEI foram repetidas após 28 dias, sacrificando-se os animais e removendo-se esôfago médio e distal, junção esofagogástrica, fundo e corpo gástricos para estudo histológico. Previamente ao experimento, três projetos pilotos foram desenvolvidos. O primeiro designado como “Projeto Piloto: Refluxo Gastroesofágico por pHmetria de 24H” (RGE 24H) buscou a via de acesso transnasal para registro de pHmetria por 24 horas. No segundo, designado “Projeto Piloto: Esofagostomia”, para confirmação de refluxo gastroesofágico espontâneo em suínos da raça Large White, utilizou-se anestesia com associação de tiletamina 125 mg e zolazepam 125 mg em combinação com um sedativo, a xilazina a 2% . A pHmetria foi mantida por 24 horas. Os dados descritos por Kadirkamanathan et al. não foram reproduzidos no nosso laboratório. Optou-se então pela realização de um terceiro projeto, “Projeto Piloto: Gastrostomia” para induzir refluxo gastroesofágico através de um modelo experimental e testar a reprodutibilidade da Pressão de Vazão Gástrica. Obteve-se sucesso. Resultados: Trinta e sete animais foram estudados em 60 intervenções no Laboratório de motilidade experimental. O projeto piloto “RGE:24h” foi abandonado após perda de 5 animais pela anestesia com halotano e, solucionada esta questão, a sistemática infecção do tecido celular subcutâneo nasal, dificultando a manutenção do cateter de phmetria em outros 5 animais. No “Projeto Piloto: Esofagostomia”, em cinco animais estudados (cada animal em duas ocasiões diferentes) não se reproduziram os achados de refluxo espontâneo. No terceiro projeto “Projeto Piloto: Gastrostomia” quatro animais foram estudados em dois momentos diferentes obtendo-se sucesso e reprodutibilidade XXIdos dados. Criado o modelo experimental, quatorze suínos foram submetidos ao experimento com implante endoscópico de PMMA com os seguintes resultados: A média dos pesos com 8 semanas de idade foi 14,98 ± 2,43 e 28 dias após o implante, 20,26 ± 3,68. O ganho ponderal foi considerado normal para a espécie. A Pressão de Vazão Gástrica média no dia 1 foi 8,08 mmHg e no dia 28, 10,69mmHg (Teste t de Student: t = 2,72 gl = 13 p = 0,017). Os Volumes de Vazão Gástricos médios foram: 392,86 ml para o dia 1 e 996,71 ml no dia 28 (teste t de Student: t = 11,66 gl = 13 p< 0,001). A Pressão Basal do EEI e o comprimento do esfíncter, não apresentaram diferenças estatisticamente significativas. PMMA foi identificado como depósitos de grandes vacúolos no tecido intersticial ao exame histológico da junção esofagogástrica associado a histiócitos, plasmócitos e presença de células gigantes tipo Langhans indicando reação tecidual de corpo estranho em todos os animais. Fibrose e macrófagos com vacúolos intracelulares estiveram presentes em menor freqüência. Conclusões: 1. O modelo experimental, em suínos, desenvolvido viabilizou o estudo do Refluxo Gastroesofágico através da Pressão de Vazão Gástrica e Volume de Vazão Gástrico; 2. O implante de PMMA, no presente estudo, aumentou a Pressão de Vazão e o Volume de Vazão Gástricos, mas não a Pressão Basal do EEI, nem tampouco aumentou o seu comprimento; 3. Depósito de PMMA implantado e evidência de processo inflamatório crônico e reação tecidual de corpo estranho foi encontrada no local do implante de PMMA. Macrófagos com vacúolos intracelulares e fibrose foram encontrados com menos freqüência.

Intervenção dietoterápica em portadores de lipodistrofia generalizada congênita do Rio Grande do Norte

Congenital generalized lipodystrophy is a rare genetic disease with autosomal recessive inheritance characterized by the generalized absence of subcutaneous adipose tissue and insulin resistance. The aim of our study was to determine the profile of patients with congenital generalized lipodystrophy (Berardinelli-Seip syndrome) through their clinical history, eating habits, and socioeconomic and cultural aspects; assess food consumption and nutritional status of the study group; propose and evaluate a diet therapy model associated to oral supplementation with zinc to help in the control and prevention of metabolic complications associated to the pathology. Initial assessment of food consumption indicated a voracious appetite in all the patients studied. The introduction of zinc reduced appetite, contributing to patient adherence to the food plan proposed. It was also observed that the proposed diet contributed mainly to glycidic control, specifically with respect to HbA1c. The nutritional status of the patients investigated was adequate in terms of body mass index (BMI), arm muscle circumference (AMC), arm muscle area AMA, but triceps skinfold (TSF) indicated serious malnutrition. Our study is unique in the literature and provides important information to the field of nutrition and to individuals with this pathology. Furthermore, it contemplates the interdisciplinary and multidisciplinary requirements of the Postgraduate Program in Health Sciences of the Federal University of Rio Grande do Norte (UFRN), Natal, Brazil

Obtenção de sistemas multiparticulados de isoniazida revestidos com polímero de liberação entérica

Known for thousands of years, tuberculosis (TB) is the leading cause of mortality by a single infectious disease due to lack of patient adherence to available treatment regimens, the rising of multidrug resistant strains of TB (MDR-TB) and co-infection with HIV virus. Isoniazid and rifampicin are the most powerful bactericidal agents against M. tuberculosis. Because of that, this couple of drugs becomes unanimity in anti-TB treatment around the world. However, the rifampicin in acidic conditions in the stomach can be degraded rapidly, especially in the presence of isoniazid, which reduces the amount of available drug for absorption, as well as its bioavailability, contributing to the growing resistance to tuberculostatic drugs. Rifampicin is well absorbed in the stomach because of its high solubility between pH 1 and 2 and the gastric absorption of isoniazid is considered poor, therefore it is mostly intestinal. This work has as objective the development of gastro-resistant multiple-systems (granules and pellets) of isoniazid aiming to prevent the contact with rifampicin, with consequent degradation in acid stomach and modulate the release of isoniazid in the intestine. Granules of isoniazid were obtained by wet method using both alcoholic and aqueous solutions of PVP K-30 as aggregating and binder agent, at proportions of 5, 8 and 10%. The influence of the excipients (starch, cellulose or filler default) on the physical and technological properties of the granules was investigated. The pellets were produced by extrusionesferonization technique using isoniazid and microcrystalline cellulose MC 101 (at the proportion of 85:15) and aqueous solution of 1% Methocel as platelet. The pellets presented advantages over granular, such as: higher apparent density, smaller difference between apparent and compaction densities, smoother surface and, especially, smaller friability, and then were coated with an organic solution of Acrycoat L 100 ® in a fluidized bed. Different percentages of coating (15, 25 and 50%) were applied to the pellets which had their behavior evaluated in vitro by dissolution in acidic and basic medium. Rifampicin dissolution in the presence of uncoated and coated isoniazid pellets was evaluated too. The results indicate that the gastro resistance was only achieved with the greatest amount of coating and isoniazid is released successfully in basic step. The amount of rifampicin in the dissolution medium when the isoniazid pellets were not coated was lower than in the presence of enteric release pellets. Therefore, the polymer Acrycoat L 100 ® was efficient for coating with gastro-resistant function and can solve the problem of low bioavailability of rifampicin and help to reduce its dosage

Adesão ao tratamento, acesso e qualidade da assistência em Aids no Brasil

A adesão à terapia antirretroviral (TARV) é crucial para a efetividade e o impacto do tratamento da Aids. Este artigo discute as relações entre adesão e qualidade dos serviços de assistência a pessoas vivendo com Aids (PVA), evidenciando a qualidade como elo central entre adesão e acesso. Está baseado nos resultados de pesquisas que conduzimos sobre a atenção a PVA no Brasil. Nossos estudos apontam que os grupos de pacientes acompanhados em serviços com número inferior a 100 pacientes apresentam risco estimado de não adesão maior do que os grupos acompanhados em serviços com mais de 500 pacientes. Apontam também que serviços com menos de 100 pacientes têm risco estimado maior de pertencer a grupos de má qualidade. Isto está relacionado à baixa complexidade observada nos serviços de menor porte caracterizada por: dificuldades em manter uma estrutura mínima de recursos humanos e materiais, simplificação da organização dos processos de trabalho, centramento no trabalho autônomo do profissional médico e gerenciamento sem projeto técnico. Há necessidade de pautar novos estudos sobre adesão e qualidade. As evidências existentes já apontam, porém, a necessidade de revisão na alocação dos serviços de assistência a PVA, bem como a de homogeneizar a qualificação destes serviços, condições necessárias para a manutenção de taxas aceitáveis de adesão à TARV no país.

Transtorno afetivo bipolar: perfil farmacoterapêutico e adesão ao medicamento

This cross-sectional and descriptive study aimed to verify the adherence of patients with Bipolar Affective Disorder (BAD) to medication and to identify possible causes of adherence and non-adherence to medication according to the pharmacotherapeutic profile. The study was carried out in a mental health service in a city in the interior of the state of Sao Paulo. Participants included 101 patients with BAD. Structured interviews and the Morisky-Green test were used for data collection, and the Statistical Package for Social Science was employed for data analysis. Most subjects (63%) did not adhere to medication. Although there were no significant differences between the adherent and non-adherent groups for the researched variables, the use of polypharmacotherapy and complex treatment regimens was observed in treatment for BAD. In practice, implementing strategies to improve the adherence of patients to medication treatment remains a challenge.

Systemic therapy for atopic dermatitis.

Systemic therapy for atopic dermatitis (AD) is indicated in patients with severe disease refractory to adequate topical treatment. Currently available drugs aim to decrease inflammation by suppressing and/or modulating immune responses and thus may indirectly improve skin barrier function, resulting in a decrease in clinical signs and symptoms in particular pruritus. Before considering systemic treatment, patient adherence to topical treatment including skin care has to be ensured. The selection of the drug depends on the disease severity, localization, complications, concomitant diseases, and age of the patient, but also on their availability and costs as well as the doctor's experience. Bearing in mind the potential risk of resistance, systemic therapy with antibiotics should be exclusively considered in clinically manifest infections such as in children. Here, we review recently published clinical trials and case reports on systemic therapy of pediatric and adult patients with AD to draw conclusions for clinical practice. Although AD is a common disease, controlled clinical studies investigating the efficacy of systemic drugs are scarce, except for cyclosporine, which has been approved for the therapy of severe AD.

A review of telemedicine and asthma

The literature contains a number of reports of early work involving telemedicine and chronic disease; however, there are comparatively few studies in asthma. Most of the telemedicine studies in asthma have investigated the use of remote monitoring of patients in the home, e.g. transmitting spirometry data via a telephone modem to a central server. The primary objective of these studies was to improve management. A secondary benefit was that patient adherence to prescribed treatment is also likely to be improved. Early results are encouraging; home monitoring in a randomized controlled trial in Japan significantly reduced the number of emergency room visits by patients with poorly controlled asthma. Other studies have described the cost-benefits of a specialist asthma nurse who can manage patients by telephone contact, as well as deliver asthma education. Many web-based systems are available for the general public or healthcare professionals to improve education in asthma, although their quality is highly variable. The work on telemedicine in asthma clearly shows that the technique holds promise in a number of areas. Unfortunately - as in telemedicine generally - most of the literature in patients with asthma refers to pilot trials and feasibility studies, with short-term outcomes. Large-scale, formal research trials are required to establish the cost effectiveness of telemedicine in asthma.

Formulation design considerations for oral vaccines

Whilst oral vaccination is a potentially preferred route in terms of patient adherence and mass vaccination, the ability to formulate effective oral vaccines remains a challenge. The primary barrier to oral vaccination is effective delivery of the vaccine through the GI tract owing to the many obstacles it presents, including low pH, enzyme degradation and bile-salt solubilization, which can result in breakdown/deactivation of a vaccine. For effective immune responses after oral administration, particulates need to be taken up bythe M cells however, these are few in number. To enhance M-cell uptake, particle characteristics can be optimized with particle size, surface charge, targeting groups and bioadhesive properties all being considerations. Yet improved uptake may not translate into enhanced immune responses and formulating particulates with inherent adjuvant properties can offer advantages. Within this article, we establish the options available for consideration when building effective oral particulate vaccines.
