Is pain relief equally efficacious and free of side effects with repeated doses of oral sucrose in preterm neonates?

The aim of the present study was to examine the efficacy and potential side effects of repeated doses of oral sucrose for pain relief during procedures in NICU. Thirty-three preterm neonates were randomly allocated in blind fashion into two groups, the sucrose group (SG = 17) and the control group (CG = 16). The responses of neonates to pain and distress were assessed during blood collection on four consecutive assessment (ass.) days. For the first assessment, the neonates did not receive any solution before the blood collection procedure. During the next three days, the SG received oral sucrose (25%; 0.5 ml/kg) and the CG received sterile water, 2 min before each minor acute painful procedure. The neonates were evaluated during blood collection each morning. The assessment was divided into five phases: Baseline (BL), Antisepsis (A), Puncture (P), Dressing (D), and Recovery (R). The neonates` facial activity (NFCS), behavioral state, and heart rate were evaluated. The data analysis used cut-off scores for painful and distressful responses. No side effects of using sucrose were detected. There were significantly fewer SG neonates with facial actions signaling pain than CG neonates in P (ass.2) and in A (ass.3). We found significantly fewer SG neonates in the awake state than CG neonates in P (ass.2 and ass.4). There were significantly fewer SG neonates crying during A (ass.2), P (ass.2 and ass.4), and D (ass.3). There was no statistical difference between-groups for physiological response. The efficacy of sucrose was maintained for pain relief in preterm neonates with no side effects. (C) 2007 International Association for the Study of Pain. Published by Elsevier B.V.

Effects of progressive exercise during phase I cardiac rehabilitation on the heart rate variability of patients with acute myocardial infarction

Purpose. aEuro integral Heart rate variability (HRV) decreases after an acute myocardial infarction (AMI) due to changes in cardiac autonomic balance. The purpose of the present study, therefore, was to evaluate the effects of a progressive exercise protocol used in phase I cardiac rehabilitation on the HRV of patients with post-AMI. Material and methods. aEuro integral Thirty-seven patients who had been admitted to hospital with their first non-complicated AMI were studied. The treated group (TG, n == 21, age == 52 +/-+/- 12 years) performed a 5-day programme of progressive exercise during phase I cardiac rehabilitation, while the control group (CG, n == 16, age == 54 +/-+/- 11 years) performed only respiratory exercises. Instantaneous heart rate (HR) and RR interval were acquired by a HR monitor (Polar (R) A (R) S810i). HRV was analysed by frequency domain methods. Power spectral density was expressed as normalised units (nu) at low (LF) and high (HF) frequencies, and as LF/HF. Results. aEuro integral After 5 days of progressive exercise, the TG showed an increase in HFnu (35.9 +/-+/- 19.5 to 65.19 +/-+/- 25.4) and a decrease in LFnu and LF/HF (58.9 +/-+/- 21.4 to 32.5 +/-+/- 24.1; 3.12 +/-+/- 4.0 to 1.0 +/-+/- 1.5, respectively) in the resting position (p < 0.05). No changes were observed in the CG. Conclusions. aEuro integral A progressive physiotherapeutic exercise programme carried out during phase I cardiac rehabilitation, as supplement to clinical treatment increased vagal and decreased sympathetic cardiac modulation in patients with post-AMI.

Effects of adding polyclonal antibody preparations on ruminal fermentation patterns and digestibility of cows fed different energy sources

Nine ruminally cannulated cows fed different energy sources were used to evaluate an avian-derived polyclonal antibody preparation (PAP-MV) against the specific ruminal bacteria Streptococcus bovis, Fusobacterium necrophorum, Clostridium aminophilum, Peptostreptococcus anaerobius, and Clostridium stick-landii and monensin (MON) on ruminal fermentation patterns and in vivo digestibility. The experimental design was three 3 x 3 Latin squares distinguished by the main energy source in the diet [dry-ground corn grain (CG), high-moisture corn silage (HMCS), or citrus pulp (CiPu)]. Inside each Latin square, animals received one of the feed additives per period [none (CON), MON, or PAP-MV]. Dry matter intake and ruminal fermentation variables such as pH, total short-chain fatty acids (tSCFA), which included acetate, propionate, and butyrate, as well as lactic acid and NH(3)-N concentration were analyzed in this trial. Total tract DM apparent digestibility and its fractions were estimated using chromic oxide as an external marker. Each experimental period lasted 21 d. Ruminal fluid sampling was carried out on the last day of the period at 0, 2, 4, 6, 8, 10, and 12 h after the morning meal. Ruminal pH was higher (P = 0.006) 4 h postfeeding in MON and PAP-MV groups when compared with CON. Acetate: propionate ratio was greater in PAP-MV compared with MON across sampling times. Polyclonal antibodies did not alter (P > 0.05) tSCFA, molar proportion of acetate and butyrate, or lactic acid and NH(3)-N concentration. Ruminal pH was higher (P = 0.01), 4 h postfeeding in CiPu diets compared with CG and HMCS. There was no interaction between feed additive and energy source (P > 0.05) for any of the digestibility coefficients analyzed. Starch digestibility was less (P = 0.008) in PAP-MV when compared with CON and MON. In relation to energy sources, NDF digestibility was greater (P = 0.007) in CG and CiPu vs. the HMCS diet. The digestibility of ADF was greater (P = 0.002) in CiPu diets followed by CG and HMCS. Feeding PAP-MV or monensin altered ruminal fermentation patterns and digestive function in cows; however, those changes were independent of the main energy source of the diet.

Effects of equine chorionic gonadotropin and type of ovulatory stimulus in a timed-AI protocol on reproductive responses in dairy cows

The objectives were to evaluate the effects of equine chorionic gonadotropin (eCG) supplementation (with or without eCG) and type of ovulatory stimulus (GnRH or ECP) on ovarian follicular dynamics, luteal function, and pregnancies per AI (P/AI) in Holstein cows receiving timed artificial insemination (TAI). On Day 0, 742 cows in a total of 782 breedings, received 2 mg of estradiol benzoate (EB) and one intravaginal progesterone (P4) insert (CIDR). On Day 8, the CIDR was removed, and all cows were given PGF2 alpha and assigned to one of four treatments in a 2 x 2 factorial arrangement: (1) CG: GnRH 48 h later; (2) CE: ECP; (3) EG: eCG + GnRH 48 It later; (4) EE: eCG + ECP. There were significant interactions for eCG x ovulatory stimulus and eCG x BCS. Cows in the CG group were less likely (28.9% vs. 33.8%; P < 0.05) to become pregnant compared with those in the EG group (odds ratio [OR] = 0.28). There were no differences in P/AI between CE and EE cows (30.9% vs. 29.1%; OR = 0.85; P = 0.56), respectively. Thinner cows not receiving eCG had lower P/AI than thinner cows receiving eCG (15.2% vs. 38.0%; OR = 0.20; P < 0.01). Treatment with eCG tended to increase serum progestesterone concentrations during the diestrus following synchronized ovulation (P < 0.10). However, the treatment used to induce ovulation did not affect CL volume or serum progesterone concentrations. In conclusion, both ECP and GnRH yielded comparable P/AI. However, eCG treatment at CIDR removal increased pregnancy rate in cows induced to ovulate with GnRH and in cows with lower BCS. (C) 2009 Elsevier Inc. All rights reserved.

Low-fluence CO(2) laser irradiation decreases enamel solubility

This study investigated whether subablative-pulsed CO(2) laser (10.6 mu m) irradiation, using fluences lower than 1 J/cm(2), was capable of reducing enamel acid solubility. Fifty-one samples of bovine dental enamel were divided into three groups: control group, which was not irradiated (CG); group laser A (LA) irradiated with 0.3 J/cm ; and group laser B (LB) irradiated with 0.7 J/cm(2). After irradiation, the samples were subjected to demineralization in an acetate buffer solution and were then analyzed by SEM. A finite-element model was used to calculate the temperature increase. The calcium and phosphorous content in the demineralization solution were measured with an ICP-OES. ANOVA and the t-test pairwise comparison (p < 0.016) revealed that LB showed significantly lower mean Ca and P content values in the demineralization solution than other groups. A reduction in the enamel solubility can be obtained with pulsed CO(2) laser irradiation (0.7 J/cm(2), 135 mJ/pulse, 74 Hz, 100 mu s) without any surface photomodification and a less than 2 degrees C temperature increase at a 3-mm depth from the surface.

Cheilitis glandularis: A clinicopathological study in 22 patients

Background: Cheilitis glandularis (CG) is a condition in which thick Saliva is secreted by minor labial salivary glands and adheres to a swollen lip causing discomfort to the patient. Most Publications refer to single case reports or small case series. Objective. We sought to report and to analyze clinical, pathological, and therapeutic data oil 22 patients with CG seen at the department of dermatology at our university. Method: Retrospective data about 22 patients with CG are reviewed and presented. Results: Seventeen patients were male and 5 were female. All were fair skinned, including 6 albino individuals. Several of them presented significant signs of photodamage on the lips. treatment was performed in 10 severely affected patients and consisted of I vermilionectomy followed by minor salivary gland removal. Histopathological Study revealed Various degrees of chronic sialadenitis and vermilion epithelial changes. Superficially invasive and in Situ squamous cell carcinoma of the vermilion was detected in 3 cases. Limitations: Biopsy and surgery were not performed in all patients. Conclusions: CG is strongly related to Sun sensitivity and may be more severe in albino patients. The swollen, sun-exposed lip may become more susceptible to the occurrence of squamous Cell carcinoma. (J Am Acad Dermatol 2010;62:233-8.)

Shoulder movement after breast cancer surgery: results of a randomised controlled study of postoperative physiotherapy

Breast screening programmes have facilitated more conservative approaches to the surgical and radiotherapy management of women diagnosed with breast cancer. This study investigated changes in shoulder movement after surgery for primary, operable breast cancer to determine the effect of elective physiotherapy intervention. Sixty-five women were randomly assigned to either the treatment (TG) or control group (CG) and assessments were completed preoperatively, at day 5 and at 1 month, 3, 6, 12 and 24 months postoperatively. The CG only received an exercise instruction booklet in comparison to the TG who received the Physiotherapy Management Care Plan (PMCP). Analyses of variance revealed that abduction returned to preoperative levels more quickly in the TG than in the CG. The TG women had 14degrees more abduction at 3 months and 7degrees at 24 months. Functional recovery at 1 month was greater in those randomised to the TG, with a dominant operated arm (OA) or receiving breast-conserving surgery. However, it was not possible to predict recovery over the 2 years postoperatively on the basis of an individual woman's recovery at 1 month postoperatively. The eventual recovery of abduction or flexion range of movement was not related to the dominance of the OA nor to the surgical procedure performed. The PMCP provided in the early postoperative period is effective in facilitating and maintaining the recovery of shoulder movement over the first 2 years after breast cancer surgery.

Physiotherapy after breast cancer surgery: results of a randomised controlled study to minimise lymphoedema

The development of secondary arm lymphoedema after the removal of axillary lymph nodes remains a potential problem for women with breast cancer. This study investigated the incidence of arm lymphoedema following axillary dissection to determine the effect of prospective monitoring and early physiotherapy intervention. Sixty-five women were randomly assigned to either the treatment (TG) or control group (CG) and assessments were made preoperatively, at day 5 and at 1, 3, 6, 12 and 24 months postoperatively. Three measurements were used for the detection of arm lymphoedema: arm circumferences (CIRC), arm volume (VOL) and multi-frequency bioimpedance (MFBIA). Clinically significant lymphoedema was confirmed by an increase of at least 200 ml from the preoperative difference between the two arms. Using this definition, the incidence of lymphoedema at 24 mo. was 21%, with a rate of 11% in the TG compared to 30% in the CG. The CIRC or MFBIA methods failed to detect lymphoedema in up to 50% of women who demonstrated an increase of at least 200 ml in the VOL of the operated arm compared to the unoperated arm. The physiotherapy intervention programme for the TG women included principles for lymphoedema risk minimisation and early management of this condition when it was identified. These strategies appear to reduce the development of secondary lymphoedema and alter its progression in comparison to the CG women. Monitoring of these women is continuing and will determine if these benefits are maintained over a longer period for women with early lymphoedema after breast cancer surgery.

Total energy expenditure and body composition changes following peripheral blood stem cell transplantation and participation in an exercise programme

The purpose of this investigation was to assess changes in total energy expenditure (TEE), body weight (BW) and body composition following a peripheral blood stem cell transplant and following participation in a 3-month duration, moderate-intensity, mixed-type exercise programme. The doubly labelled and singly labelled water methods were used to measure TEE and total body water (TBW). Body weight and TBW were then used to calculate percentage body fat (%BF), and fat and fat-free mass (FFM). TEE and body composition measures were assessed pretransplant (PI), immediately post-transplant (PII) and 3 months post-PII (PIII). Following PII, 12 patients were divided equally into a control group (CG) or exercise intervention group (EG). While there was no change in TEE between pre- and post-transplant, BW (P

Immunological changes after cancer treatment and participation in an exercise program

Purpose: The purpose of this investigation was to evaluate the impact of undertaking peripheral blood stem cell transplantation (PBST) on T-cell number and function, and to determine the role of a mixed type, moderate intensity exercise program in facilitating the recovery of T-cell number and function. Methods: Immunological measures of white blood cell, lymphocyte, CD3(+), CD4(+), and CD8(+) counts, and CD3(+) cell function were assessed pretransplant (PI), immediately posttransplant (PII), and 1 month (II), 2 months (12) and 3 months (PIII) posttransplant. After PII, 12 patients were divided equally into a control group (CG) or exercise intervention group (EG). Results: Lower total T-cell, helper T-cell, and suppressor T-cell counts (P < 0.01), as well as lower T-cell function (P < 0.01), when compared with normative data, were found at PI. More specifically, 88% of the group had CD3(+), CD4(+), and CD8(+) counts that were more than 40%, 20%, and 50% below normal at PI, respectively. Undertaking a PBST caused further adverse changes to the total leukocyte, lymphocyte, CD3(+), CD4(+) and CD8(+) count. and the helper/suppressor ratio. Although CD8(+) counts had returned to normal by PIII, CD3(+), CD4(+), and the CD4(+)/CD8(+) ratio remained significantly lower than normative data (P < 0.01), with 66%, 100%, and 100% of the subject group reporting counts and ratios, respectively, below the normal range. Conclusion: The PBST patients were immunocompromised before undertaking the transplant, and the transplant procedure imposed further adverse changes to the leukocyte and lymphocyte counts. The leukocyte and CD8(+) counts returned to normal within 3 months posttransplant; however, the other immunological parameters assessed demonstrated a delayed recovery. Although participation in the exercise program did not facilitate a faster immune cell recovery, neither did the exercise program hinder or delay recovery.

Perfil da composição química e atividades antibacteriana e antioxidante do óleo essencial do cravo-da-índia (Eugenia caryophyllata Thunb.)

A busca por substâncias antibacterianas e antioxidantes naturais tem sido alvo de diversos estudos científicos. Foi objetivo determinar as atividades antibacteriana e antioxidante e a concentração inibitória mínima do óleo essencial do cravo-da-índia, obtido por hidrodestilação. O estudo por CG-EM identificou o eugenol como o constituinte majoritário do óleo essencial e os testes de atividade antibacteriana mostraram bons resultados para quase todos os microorganismos avaliados. Os valores de concentração inibitória mínima variaram de 0,2 mg.mL-1 a 0,6 mg.mL-1. Aatividade antioxidante demonstrou uma correlação linear com a concentração de óleo essencial. Os resultados demonstraram potencial antibacteriano e antioxidante do óleo essencial de Eugenia caryophyllata, constituindo-se uma opção para a formulação de novos produtos alimentícios.

Polygala paniculata: um recurso de salicilato de metila produzido por cultura de tecidos vegetais

O estabelecimento de cultura in vitro de Polygala paniculata L. permitiu a propagação rápida de matéria-prima vegetal sob condições assépticas e padronizadas. As plantas in vitro foram submetidas à extração e destilação simultâneas (EDS) e a composição química do óleo essencial foi analisada por CG/DIC e CG/EM. Foram avaliados os efeitos de BAP (6-benzilaminopurina) sobre o desenvolvimento in vitro e produção de voláteis em P. paniculata. A principal característica do óleo essencial consistiu na presença marcante de salicilato de metila. Plantas cultivadas em meio controle MS (Murashige & Skoog) produziram mais do que 80% de salicilato, enquanto o uso de BAP, reduziu a produção de salicilato de metila a 71% e 21% para as concentrações de 2 e 4 mg L-1, respectivamente. A cultura de tecidos de P. paniculata pode ser indicada como fonte de salicilato de metila.

Produção vegetal e de óleo essencial de boldo pequeno em função de fontes de adubos orgânicos

A aplicação de fertilizantes orgânicos, em plantas medicinais e aromáticas, normalmente modifica positivamente a produção vegetal e de óleo essencial. Neste contexto, tendo por fim avaliar a resposta de plantas de Plectranthus neochilus Schltr., cultivadas com diferentes fontes de adubos orgânicos, o presente trabalho estudou a produção de biomassa, teor, rendimento e composição química do óleo essencial. As mudas, após a aclimatização, foram transplantadas para vasos de dez litros, acondicionados em casa de vegetação. O experimento foi constituído por quatro tratamentos e quatro repetições (16 parcelas), sendo cada parcela composta por cinco vasos. Os tratamentos foram: ausência de adubo orgânico (testemunha); aplicação de 60 t ha-1 de esterco bovino; 30 t ha-1 de esterco avícola; 60 t ha-1 de composto orgânico. Aos 120 dias de cultivo, as plantas foram colhidas e uma parte das folhas frescas foi destinada à extração do óleo essencial. O restante do material vegetal foi seco em estufa, até atingir peso constante, para a determinação da biomassa seca. As análises químicas do óleo foram realizadas por cromatografia gasosa (CG-DIC e CG-EM). As fontes de adubo orgânico testadas promoveram diferenças entre os tratamentos em relação à produção de biomassa, rendimento e composição do óleo essencial de P. neochilus. A utilização de diferentes fertilizantes orgânicos não modificou o teor de óleo volátil.

Influência da idade da planta na produção de óleo essencial de alevante

O teor de óleo essencial e a sua composição química são características genéticas e podem ser influenciados pelo ambiente e pelo estádio de desenvolvimento ou idade da planta. Dessa forma, objetivou-se, com este trabalho, avaliar a influência da idade da planta sobre a produção e a qualidade do óleo essencial de alevante. O experimento foi conduzido em Ilhéus, BA, no período de maio a dezembro de 2009. Os tratamentos foram constituídos da colheita, em seis idades da planta (60, 90, 120, 150, 180 e 210 dias após o transplante), utilizando-se o delineamento inteiramente casualizado, com quatro repetições. O óleo essencial foi obtido por hidrodestilação, em aparelho de Clevenger modificado. A identificação dos constituintes químicos foi realizada por cromatografia gasosa acoplada ao espectrômetro de massas (CG-EM). O maior teor do óleo essencial (1%) ocorreu aos 120 dias e o maior teor dos compostos majoritários α-fenchol (49,92%) e cis-mirtanol (30,03%), aos 120 e 150 dias após o transplante, respectivamente.
