Desarrollo y morfología del fruto y la semilla del género hemiparásito <i>Jodina</i> (Cervantesiaceae)

The monotypic genus Jodina is endemic to central and southeastern South America, common in forests and scrubland environments. The fruit type in Jodina is controversial since it has been described at different stages of development. The main objective of this work was to analyze the morphology of the fruit of J. rhombifolia during its maturation to attain a consensus about its type. Also characteristics of seed development and anatomy were analyzed in detail. Material was processed according to conventional techniques for LM and SEM studies. The fruit of J. rhombifolia is a pseudodrupe since the ovary is half-inferior; the fleshy layer of the pericarp is constituted by an increase of the nectary disk whereas the stony layer is represented by the mesocarp. Participation of the nectary disk as part of the fruit wall has not been mentioned previously. The seed is "naked" -the integument disintegrates during development- and the resulting structure is a pyrene. The interpretations made by other authors on the fruit of Jodina are also discussed.El género monotípico Jodina es endémico del centro y sureste de América central, común en bosques y ambientes de matorral. El tipo de fruto en Jodina es controvertido, ya que se ha descrito en diferentes etapas de su desarrollo.

Asimismo, se analizaron en detalle diferentes características del desarrollo y la anatomía de la semilla. El material se estudió de acuerdo con las técnicas convencionales utilizadas en estudios con MO y MEB. El fruto de J. rhombifolia es una pseudodrupa, dado que el ovario es semiínfero; la capa carnosa del pericarpio está constituida por un engrosamiento del disco y la capa dura está representada por el mesocarpio. La participación del disco como parte de la pared del fruto no se ha mencionado anteriormente. La semilla es “desnuda” —el tegumento se desintegra durante el desarrollo— y la estructura resultante es un pireno.

Efficacy of a mandibular advancement intraoral appliance (MOA) for the treatment of obstructive sleep apnea syndrome (OSAS) in pediatric patients : a pilot-study

To evaluate the treatment efficacy of a mandibular advancement intraoral appliance (MOA) for treatment of obstructive sleep apnea syndrome (OSAS) in pediatric patients. Eighteen patients (mean=8.39 years old, women=44.4%) were selected. Sleep disorders, sleep bruxism, and temporomandibular disorders were assessed by the Sleep Disturbance Scale for Children (SDSC), the BiteStrip® (portable SB device), and the Research Diagnostic Criteria for Temporomandibular Disorders, respectively. The clinical diagnosis of OSAS was confirmed with a type 3 portable monitor device (ApneaLinkTM Plus). A silicon-based material MOA was used by patients for 60 days, and the results were compared to baseline. The median RDI was significantly reduced from 10 to 4.5 events/hour. Nadir SpO2 significantly increased from 82.6% to 88.9%. Total snoring events/hour have also significantly decreased from 205.5 to 91.5. Signs and symptoms of TMD remained unaltered. There was also a reduction from moderate to absence of SB in 12 patients. Similarly, all variables measured by the SDSC have had very significant reductions: disorders of initiating and maintaining sleep, sleep disordered breathing, disorders of arousal, nightmares, sleep wake transition disorders, disorders of excessive somnolence, and sleep hyperhidrosis. In selected cases, OA maybe considered as an alternative for the OSAS treatment

Clinical outcomes of medication therapy management services in primary health care

This study evaluates whether the integration of pharmacists into health-care teams through the delivery of pharmaceutical care-based medication therapy management (MTM) services can improve the clinical outcomes of patients with chronic health conditions in the primary health-care setting. A retrospective descriptive study of 92 outpatients assisted by MTM pharmacists in primary health-care units was carried out over 28 months (median follow-up: 05 months). Patients were followed up by MTM pharmacists, with a total of 359 encounters and a ratio of 3.9 encounters per patient. The prevalence of hypertension, diabetes mellitus and dyslipidaemia was 29.5%, 22.0% and 19.4%, respectively. There was a high prevalence of drug-related problems with a ratio of 3.4 per patient. Pharmacists performed a total of 307 interventions to prevent or resolve drug-related problems. With regard to control of the most prevalent chronic medical conditions, a high percentage of patients reached their therapy goals by the last encounter with the pharmacist: 90.0% for hypertension, 72.3% for diabetes mellitus and 90.3% for dyslipidaemia. MTM services provided by pharmacists resolved drug therapy problems and improved patients' clinical outcomes. This study provides evidence for health-care managers of the need to expand the clinical role of pharmacists within the Brazilian public health-care system

Estudo de caso em uma empresa do setor madeireiro do Alto Paranaíba: uma proposta de implementação da gestão da qualidade total e da gestão da rotina / Quality management and current approaches: a case study in a logging company located in the Alto Paranaíba

O objetivo desse artigo consistiu em identificar, em uma empresa do setor madeireiro situada na mesorregião do Alto Paranaíba, características do gerenciamento da qualidade voltados para a Gestão da Qualidade Total (TQM) e uma de suas abordagens atuais, o Gerenciamento da Rotina do Dia-a-Dia (GRD). Para atingi-lo, foram coletados dados na empresa foco do trabalho, mediante entrevista com o gerente da produção e de observação buscando realizar o alinhamento entre teoria e prática. Dentre os resultados, discutiu-se a viabilidade da proposta de aplicação do GRD para o microprocesso prioritário identificado na empresa, a saber, o processo de produção do principal produto da empresa, a porta. Visando a melhoria contínua, sugeriu-se a implementação da metodologia CEDAC, a fim de incentivar a participação dos funcionários na busca pela melhoria contínua das atividades realizadas no dia a dia

Controle postural em pacientes com lesão do ligamento cruzado anterior

A lesão do ligamento cruzado anterior (LCA) do joelho acarreta alterações somatosensoriais em função da perda de informações provenientes dos mecanorreceptores presentes no LCA. Esses receptores constituem importante fonte de informação sensorial, afetando o desempenho de vários atos motores, dentre os quais o controle postural. O estudo objetivou analisar o controle postural de indivíduos com joelhos normais e com lesão unilateral do LCA. Participaram 15 voluntários com lesão do LCA (grupo lesado) e 15 voluntários com joelhos normais (grupo controle). O controle postural foi analisado por plataforma de força, sendo o voluntário instruído a assumir a situação experimental em apoio unipodal direito e esquerdo, posicionado no centro da plataforma de modo estático e com os olhos fechados. A plataforma de força forneceu informações de forças e momentos no eixo vertical e horizontal, a partir das quais foi obtida a área de deslocamento do centro de pressão nas direções ântero-posterior e médio-lateral. Os resultados mostram que indivíduos com lesão do LCA apresentaram maior amplitude média de oscilação comparados aos do grupo controle, sugerindo que o deficit no controle postural seja devido à perda de informações proprioceptivas nos indivíduos com LCA. Esses resultados têm implicações para a abordagem clínica de indivíduos com lesão do LCA.Anterior cruciate ligament (ACL) injury leads to sensorimotor changes due to lack of information from mechanoreceptors at the ACL. These receptors are an important source of sensory information, affecting the performance of various motor responses, among which postural control. The purpose of this study was to assess postural control in individuals with normal knees and with unilateral ACL injury. Fifteen subjects with ACL injury and 15 healthy young subjects (control group) were submitted to postural control assessment by standing in single-leg stance (both right and left) on a force platform; they stood at the centre of the platform, with eyes closed, remaining in the position for 30 seconds. The force platform provided information on forces and moments along both vertical and horizontal axes, from which was obtained the centre of pressure displacement in anterior-posterior and medial-lateral directions. Individuals with ACL injury showed greater mean sway amplitude than healthy control ones, suggesting that their deficit in postural control might be due to lack of proprioceptive information. These results have implications for the clinical approach of individuals with ACL injury
