Variabilidade da frequência cardíaca e carga máxima atingida no teste de esforço físico dinâmico em homens idosos

INTRODUÇÃO: Um dos benefícios promovidos pelo exercício físico parece ser a melhora da modulação do sistema nervoso autônomo sobre o coração. No entanto, o papel da atividade física como um fator determinante da variabilidade da frequência cardíaca (VFC) não está bem estabelecido. Desta forma, o objetivo do estudo foi verificar se há correlação entre a frequência cardíaca de repouso e a carga máxima atingida no teste de esforço físico com os índices de VFC em homens idosos. MÉTODOS: Foram estudados 18 homens idosos com idades entre 60 e 70 anos. Foram feitas as seguintes avaliações: a) teste de esforço máximo em cicloergômetro utilizando-se o protocolo de Balke para avaliação da capacidade aeróbia; b) registro da frequência cardíaca (FC) e dos intervalos R-R durante 15 minutos na condição de repouso em decúbito dorsal. Após a coleta, os dados foram analisados no domínio do tempo, calculando-se o índice RMSSD, e no domínio da frequência, calculando-se os índices de baixa frequência (BF), alta frequência (AF) e razão BF/AF. Para verificar se existe associação entre a carga máxima atingida no teste de esforço e os índices de VFC foi aplicado o teste de correlação de Pearson (p < 0,05). RESULTADOS: Características demográficas, antropométricas, fisiológicas e carga máxima atingida no teste ergométrico: idade = 63 ± 3,0 anos; IMC = 24 ± 2kg/m²; FC = 63 ± 9bpm; PAS = 123 ± 19mmHg; PAD = 83 ± 8mmHg; carga máxima = 152 ± 29 watts. Não houve correlação entre os índices de VFC com os valores de FC de repouso e carga máxima atingida no teste ergométrico (p > 0,05). CONCLUSÃO: Os índices de variabilidade da frequência cardíaca temporal e espectrais estudados não são indicadores do nível de capacidade aeróbia de homens idosos avaliados em cicloergômetro.

Acupuncture as therapeutic resource in patient with bruxism

Bruxism is the harmful habit of clenching or grinding the teeth during the day and / or night, with unconscious pattern, with particular intensity and frequency, outside the functional movements of chewing and swallowing. It is accepted that bruxism is a response controlled by the neurotransmitters dopamine system associated with emotional component. The proposed of treatment of bruxism with acupuncture aims to stimulate sensory fibers of the peripheral nervous system leading to electrical transmission by neurons sufficient to produce changes in the central nervous system. As a consequence there is the release of substances (cortisol, endorphins, dopamine, noradrenaline and serotonin) that promote wellness and restoration of harmony, be it psychological, biological and / or behavioral.

Dental care for cerebral palsy patients using auxiliary resources to inhibit pathological tonic reflexes

Cerebral paralysis is a chronic illness that affects the central nervous system. In this article the author describes the techniques used at CAOE (Odontological Center for Assistance to patients with special needs) to restraint CP patients during dental treatment, because they present some pathological reflexes which interfere in their odontological assistance. Also it shows how to perform a special physical restraint and how to keep the mouth open by using simple tools including a homemade one. All the devices used during the dental treatment in cerebral palsy patients, such as the physical restraint with bands or sheet to wrap them up, cylindrical pad or cushion made of a soft material, or simple tools including a homemade one to keep the mouth open are usually and safely used in CAOE. All these simple devices are necessary, because there are no available funds for the acquisition of expensive material or equipment. Despite of a shortage of resources we can easily and efficiently assist these patients.

Medicamentos inadequados para idosos na estratégia da saúde da família

The ageing process can change the pharmacodynamics and pharmacokinetics parameters. Therefore, some medications are considered potentially inappropriate (PIM) for the elderly people, since they can increase the likelihood of occurrence of adverse drug events. The objectives are to estimate the frequency of use of PIM in the elderly people, with potentially hazardous drug interactions (PHDI) and to evaluate the impact of pharmaceutical intervention (PI) for the prescription of safer therapeutic alternatives. A cross-sectional study was performed in a Health Family Strategy (region of Araraquara, SP), between January and February/2012. The medical records of patients aged ≥60 years, that use at least one drug, were consulted for identification of PIM, according to the Beers criteria. The MPI identified were classified considering the Anatomical Therapeutic Chemical Classification System (ATC) and the essentiality of the drug (safety, effectiveness, quality and cost parameters) The inclusion criteria were met by 358 elderly, being that 93 of them (26%) had taken at least one PIM. Of the 114 different drugs prescribed for elderly, ten were classified as PIM, of which four of them act on the central nervous system, four on cardiovascular system and two on the digestive tract. Seven MPI are essential medicines, belonging to national list of essential drugs (RENAME-2010). Fourteen drug interactions were identified, of which two are PHDI (fluoxetine/amitriptyline and digoxin/hydrochlorothiazide).After the PI, there was no change in medical prescriptions of patients with PIM use or with DI. Medical prescriptions of elderly attended in the Health Family Strategy show pharmacotherapeutic safety problems, of which may be responsible for health hazardous for this age group. Although the intervention carried out by letter had been ineffective for the adherence of doctors in prescribing safe alternatives, wide dissemination of the lists that contain PIM and PHDI is need, as well as the inclusion of safer equivalents in RENAME, in order to contribute for rational use of drugs.

Selección del tratamiento farmacológico en el estado de mal epiléptico en niños

The status epilepticus (SE) is characterized by a series of crises which occur without recovery of consciousness or a single seizure lasting more than 30 minutes and can damage the central nervous system and systemic. The duration and frequency of attacks are directly related to patient prognosis. Whether seizures occur often and are longer, increase the risk of neurological and systemic complications. Child population has a higher frequency of seizures and it is associated with a lower threshold of immature brain to trigger these episodes. Aim: To determine the safest drugs prescribed for children in SE, their doses and schedules. A bibliographic survey was performed in electronic databases. Methods: The scientific health descriptors used for search was: “status epilecticus” and “anticonvulsivants” and “child”. Results: This strategy identified 396 manuscripts, of whom four were considered eligible for the study, after the assessment by floating reading and criteria. Of these, two were randomized trials and two descriptive. The studies address the use of oral midazolam, rectal diazepam and intravenous lorazepam. Conclusions: All investigated drugs were effective in treat in status epilepticus. Lorazepam is highlight, since it has fewer secondary effects and, as an alternative to the intravenous, oral midazolam. However, there is a need for further studies to demonstrate the efficacy and safety in the use of drugs in children.

Doença cerebelar em cães e gatos

Diseases of the cerebellar system are common in small animals, and result in a clinical syndrome characterized by hypermetria, base-wide stance and intentional tremors of the head and body. All movements of the limbs are spastic and awkward. The neurological examination assists in the localization of lesions restricted to the cerebellum or in the detection of disorders relating to other parts of the nervous system, which characterizes a multifocal disease process. Neurological disorders in dogs and cats may suggest a very extensive list of differential diagnoses, since they may be caused by infectious, degenerative and traumatic processes, among others. The possible etiologies for cerebellar syndrome include: aplasia and hypoplasia, abiotrophy, cancer, vascular stroke and inflammatory disorders. The aim of this paper is to review the clinical signs that aid in the location of the cerebellar lesion and discuss the possible causes of this syndrome in dogs and cats.

Meningite supurativa secundária a otite média e interna em um gato: relato de caso

Suppurative meningitis are rarely reported in dogs and cats. The present study aims to report the occurrence of suppurative meningitis secondary to otitis media and interna in a five-year-old female Persian cat examined at the Veterinary School of Unesp-Botucatu with acute progressive multifocal neurological alterations. Analysis of the cerebrospinal fluid (CSF) demonstrated predominance of neutrophils (90%) and the presence of bacteria. Therapy with antibiotics was initiated, but the animal came to die. beta-hemolytic Staphylococcus, beta-hemolytic Streptococcus and Proteus mirabilis were detected in fragments sent to culture. The present report demonstrates the importance of performing more specific exams such as complete CSF analysis in cases of otitis media and interna. This way, central nervous infections can be diagnosed and treated in a timely manner, as those are acute diseases with poor prognosis.

Glioma misto em um cão: relato de caso

Intracranial neoplasms are common causes of neurological disorders in middle-aged and elderly dogs. With the feasibility of computed tomography, it is now possible to determine the extent and exact location of brain tumors, identifying them ante mortem in dogs and cats. This paper aims to report the occurrence of a mixed glioma in a Boxer dog examined at the Veterinary Hospital of Unesp, Botucatu Campus. The animal presented with a brain syndrome of acute onset and progressive course. CT scan showed the presence of a mass in the right cerebral hemisphere extending from the frontal to the parietal region and involving the basal ganglia. Given the gravity of the neurological disorder, the owner chose to perform euthanasia. Microscopic analysis of the mass allowed the diagnosis of mixed glioma.

Sistema autônomo de iluminação utilizando energia solar

This work presents a self-sustainable lighting system using ultracapacitor as a storage device, replacing the conventional battery, using solar energy as the only energy supplier. A detailed study of solar panels, switched mode converters and ultracapacitors was made, in order to design a circuit capable of capturing solar energy and transfer it efficiently to a bank of ultracapacitors. Later, at nighttime, this energy is used for lighting in LED luminaires which have high luminous efficiency and high reliability index. This work presents the design of the solar panel, ultracapacitors bank, the development of the voltage converter circuit and charger working at the maximum power point of the solar panel. All subsystems were simulated and it was shown that the use of ultracapacitors is feasible to feed a LED lamp with enough brightness for a person to walk at night, for two night shifts, using a capacitive bank with twenty-four ultracapacitors. Replacing the battery by an ultracapacitor allows a faster recharge, with low maintenance costs, since ultracapacitors have a lifetime bigger than batteries; beyond reducing the environmental impact, as they don't use potentially toxic chemical compounds
