Breaking bad news in ophthalmology: a literature review / Comunicação de más notícias em oftalmologia: uma revisão de literatura

ABSTRACT Medical specialties have recognized that breaking bad news assists clinical practice by mitigating the impact of difficult conversations. This scenario also encourages various studies on breaking bad news in ophthalmology since certain ocular diagnoses can be considered bad news. Thus, the objective is to review the scientific literature on breaking bad news in ophthalmology. The literature databases like MEDLINE/PUBMED, EMBASE, LILACS, SCOPUS, COCHRANE, and SCIELO, were screened for related research publications. Two independent reviewers read all the articles and short-listed the most relevant ones. Seven articles, in the formats of original article, review, editorial, oral communication, and correspondence, were reviewed. Conclusively it reveals that ophthalmologists are concerned with communicating bad news effectively but lack related studies. Nevertheless, there is a growing realization that training in breaking bad news can increase physicians' confidence during communication, thus, benefiting the therapeutic relationship with the patient and his family. Therefore, it would be valuable to include breaking bad news training in the curriculum of residencies.

RESUMO O reconhecimento sobre a comunicação de más notícias como mitigadora de conversas difíceis por outras especialidades médicas, incentiva o estudo desta temática na oftalmologia. Sendo assim, o objetivo deste estudo é revisar a produção de pesquisas científicas sobre a comunicação de más notícias em oftalmologia. Para isso, foi realizada uma revisão de literatura. As bases de dados utilizadas foram MEDLINE/PUBMED, EMBASE, LILACS, SCOPUS, COCHRANE e SCIELO. Dois revisores independentes leram todos os artigos e selecionaram a amostra final. Sete artigos foram escolhidos nos formatos de artigo original, revisão, editorial, comunicação oral e correspondência. Os oftalmologistas estão preocupados em comunicar as más notícias de forma eficaz, mas faltam estudos sobre o tema. No entanto, há uma crescente percepção de que o treinamento de comunicação de más notícias aumenta a confiança dos médicos na comunicação, beneficiando a relação terapêutica. Portanto, seria valioso incluir este treinamento no currículo das residências.

Click chemistry and drug delivery: A bird's-eye view

Click chemistry has been proven to be very useful in drug delivery. Due to the availability of a large number of click reactions with a various characteristics, selection of appropriate chemistry for a given application is often not a trivial task. This review is written for pharmaceutical researchers who are interested in click chemistry applications and yet may not be click chemistry experts. For this, the review gives an overview of available click reactions organized by application types. Further, the general understanding of click reactions being fast and high yielding sometimes overshadows the need to analyze reaction kinetics in assessing suitability of a given reaction for certain applications. For this, we highlight the need to analyze the relationship among reaction kinetics, concentration effects, and reaction time scales, knowing that lack of such analysis could easily lead to failures. Further, possible issues such as chemical stability with various click reagents are also discussed to aid experimental designs. Recent examples and extensive references are also provided to aid in-depth understanding of technical details. We hope this review will help those interested in using click chemistry in drug delivery to select the appropriate reactions/reagents and minimize the number of pitfalls.

LEADERSHIP STYLE AND ORGANIZATIONAL CITIZENSHIP BEHAVIOUR: REVIEW OF LITERATURE

For an organization to remain successful, having the right leader is crucial. The best employers know how they can participate with their employees in order to achieve the organization's objectives. There are a lot of different leadership styles; among which are the autocratic, administrative, free economy, charismatic, democratic, cooperative, situational, functional, transformational, transactional, and relationship-oriented styles. Organizational Citizenship Behaviour is the criterion variable of the study. In today's world of competitive work environment OCB taking an important phenomenon at workplace, it is that behaviour of employees at work that is related to their extra work related activities for which employees not get any financial reward by the management. Organizational Citizenship Behaviour (OCB) as “discretionary and voluntary Behaviour being followed by formal reward system.” A modest attempt has been made to make survey of past studies related to leadership style and organizational citizenship behaviour

An Experimental Evaluation of humboldtia vahliana wight., a Folk Medicinal Plant on Wound Healing Action in Wistar Albino Rats-an in-vivo Study

A wound is a break in the integrity of the skin or tissues often which may be associated with disruption of the structure and function. Globally, the magnitude of acute wounds as a healthcare problem is sharply rising mainly due to industrialization. There is still a need to revisit the ancient healing methods by using traditional medicine aiming to discover a wound healing drug with better protection, rapid granulation changes, least side effects, good bio-availability and low cost.

Effect of varying dietary crude protein and metabolizable energy levels on leg abnormalities and performance in broiler chickens

Background: Nutrient restriction is a common strategy to prevent metabolic disorders in fast growing broiler chickens, but limited information is available regarding the impact of diets with low protein and energy on leg abnormalities Objective: Two experiments were conducted to evaluate the effect of varying crude protein (CP) and metabolizable energy (ME) levels on gastrocnemius tendon (GTeBS) and tibia breaking strength (TiBS), gait score (GS) and valgus/varus angulation (VAng). Methods: In Experiment 1, eight-d-old Ross 308 broilers (n=90) were randomly assigned into three treatments: 13/2,900 (13% CP and 2,900 kcal ME kg-1 of diet), 17/3,000 (17% CP and 3,000 kcal ME kg-1 of diet), and 21/3,025 or control (21% CP and 3,025 kcal ME kg-1 of diet). In Experiment 2, six-d-old Ross 308 chickens (n=192) were randomly distributed into two treatments: 16/3,000; 16% CP and 3,000 kcal ME kg-1 of diet and 21/3,000 or control; 21% CP and 3,000 kcal ME kg-1 of diet. In both experiments data were analyzed as one-way ANOVA. Results: In Experiment 1, broilers in the 17/3,000 and control treatments had similar (p>0.05) GTeBS (202 and 224 N, respectively), and TiBS (338 and 332 N, respectively). Birds in the 13/2,900 treatment showed higher GS (lower walking ability; 80% of birds with score >3), and greater VAng (53% of birds with score >2) than broilers in the control treatment (0% of birds with GS score >3 and 0% of birds with VAng score >2). Experiment 2, broilers in the 16/3,000 showed similar VAng, GS and TiBS than birds in the control treatment. However, birds in the 16/3,000 treatment showed lower (-26%) GTeBS than birds in the control treatment (p<0.05). Conclusions: Feeding broilers with 16% CP and 3,000 kcal ME kg-1 of diet did not affect tibia breaking strength, gait score and valgus/varus angulation. A diet containing 16% CP or less and 2,900-3,000 kcal ME kg-1 reduces tendon and tibia breaking strength.

Antecedentes: La restricción de nutrientes es una estrategia común para prevenir trastornos metabólicos en pollos de engorde, sin embargo, se dispone de información limitada sobre el impacto de las dietas bajas en proteína y energía en las anomalías de piernas. Objetivo: Se llevaron a cabo dos experimentos para evaluar el efecto de niveles variables de proteína cruda (PC) y energía metabolizable (EM) en la fuerza de rotura del tendón del gastrocnemio (GTeBS) y tibia (TiBS), la evaluación de marcha (GS) y la angulación en valgus/varus (VAng). Métodos: En el Experimento 1, pollos de engorde Ross 308 de ocho días de edad (n = 90) se asignaron al azar en tres tratamientos: 13/2.900; 13% PC y 2.900 kcal ME kg-1 de dieta, 17/3.000; 17% PC y 3.000 kcal ME kg-1 de dieta y 21/3.025 o control; 21% PC y 3.025 kcal ME kg-1 de dieta. En el Experimento 2, pollos Ross 308 de seis días de edad (n = 192) se distribuyeron aleatoriamente en dos tratamientos: 16/3.000; 16% PC y 3.000 kcal ME kg-1 de dieta y 21/3.000 o control; 21% PC y 3.000 kcal ME kg-1 de dieta. En ambos experimentos los datos se analizaron como ANOVA de una vía. Resultados: En el Experimento 1, los pollos de los tratamientos 17/3.000 y control tuvieron GTeBS (202 y 224 N, respectivamente) y TiBS (338 y 332 N, respectivamente) similares (p>0,05). Las aves del tratamiento 13/2.900 mostraron mayor GS (menor capacidad para caminar; 80% de las aves con puntaje >3) y mayor VAng (53% de las aves con puntaje >2) que los pollos del tratamiento control (0% de aves con un puntaje GS >3 y 0% de aves con un puntaje VAng >2). En el Experimento 2, los pollos del 16/3.000 mostraron VAng, GS y TiBS similares a los de las aves del tratamiento control. Sin embargo, las aves del tratamiento 16/3.000 mostraron menor (-26%) GTeBS que las aves control (p<0,05). Conclusiones: La alimentación de pollos de engorde con 16% PC y 3.000 kcal EM kg-1 de dieta no afecta la resistencia a la ruptura de la tibia, la marcha y la angulación valgus/varus. La dieta formulada con 16% de PC o menos y 2.900-3.000 kcal de EM kg-1 reduce la resistencia a la ruptura del tendón y de la tibia.

Antecedentes: A restrição de nutrientes é uma estratégia comum para prevenir distúrbios metabólicos em frangos de corte, no entanto, há informações limitadas disponíveis sobre o impacto de dietas de baixa proteína e baixa energia nas anormalidades de pernas destas aves. Objetivo: Dois experimentos foram realizados para avaliar o efeito de diferentes níveis de proteína bruta (PB) e energia metabolizável (EM) em força de ruptura do tendão do músculo gastrocnêmio (GTeBS), forca de ruptura da tíbia (TiBS), gait score (GS) e angulação em valgus/varus (VAng). Métodos: Experimento 1, foram utilizados 308 frangos de corte machos da linhagem Ross com oito dias de idade (n = 90) distribuidos aleatoriamente em três tratamentos: dieta controle com 21% PB e 3.025 kcal EM kg-1 13/2.900; dieta con 13% PB e 2.900 kcal EM kg-1, y 17% PB e 3.000 kcal EM kg-1 . Experimento 2, foram utilizados 308 frangos de corte da linhagem Ross com seis dias de idade (n = 192) distribuídos aleatoriamente em dois tratamentos: dieta controle con 21% PB e 3.000 kcal EM kg-1 e dieta com 16% PB e 3.000 kcal EM kg-1 . Em ambos os experimentos, os dados foram submetidos a ANOVA. Resultados: Experimento 1, os frangos de corte submetidos ao dos tratamentos 17/3.000 e controle nao apresentaram diferencas significativas (p>0,05) para as variáveis GteBS (202 y 224 N, respectivamente) e TiBS (338 y 332 N, respectivamente). Os frangos submetidos ao 13/2.900 apresentaram maior frequência de GS (menor capacidade de locomocao; 80% das aves com pontuação>3) e maior VAng (53% das aves com pontuação>2) do que os frangos do tratamento controle (0% das aves com pontuação GS>3 e 0% das aves com pontuação VAng>2). Experimento 2, os frangos do 16/3.000 apresentaram VAng, GS e TiBS semelhantes aos das aves do tratamento controle. Entretanto, as aves do tratamento 16/3.000 apresentaram GTeBS mais baixo (-26%) em comparacao as aves do tratamento de controle (p<0,05). Conclusões: A dieta com 16% PB e 3.000 kcal EM kg-1 não afetou a forca de ruptura da tíbia, gaite score marcha e angulação em valgus/varus de frangos de corte. Uma dieta com níveis de 16% de PB ou menos e 2.900-3.000 kcal EM kg-1 reduziu a resistência à ruptura do tendão e a resistência de tibia de frangos de corte.

'When all think alike, then no one is thinking': Understanding the praxis of creative insubordination as a decision-making strategy in Philippine medical schools

@#<p style="text-align: justify;"><strong>Background:</strong> Exercising discretion is vital when making decisions. While decision-making implies having to choose between predefined alternatives, discretion requires sifting through several solutions and critically choosing the desired one that implies a choice between many alternatives without rigid guidelines pointing to one direction or the other.

Breaking blood expelling stasis method accelerates hematoma resolution after hyperacute intracerebral hemorrhage and its potential mechanism / 中国医师杂志

Objective:To explore the efficacy of breaking blood expelling stasis method accelerates hematoma resolution after intracerebral hemorrhage (ICH) and its potential mechanism.Methods:63 ICH patients confirmed by computer tomography (CT) scan from August 2019 to February 2020 were selected as the research objects and randomly divided into control group ( n=29, routine treatment plus placebo) and observation group ( n=34, routine treatment plus breaking blood expelling stasis granules). The changes of neurological function and hematoma volume were observed before and after treatment. At the same time, the ICH rat model was constructed to observe the changes of neurobehavior and hematoma volume after the intervention of breaking blood expelling stasis granules. The expressions of peroxidase proliferator-activated-receptor γ(PPARγ), CD11b and CD36 in the surrounding tissues of hematoma were detected by Western blot on the third day after the intervention. Results:After two weeks of treatment, the National Institutes of Health Stroke Scale (NIHSS) score and hematoma volume of the two groups decreased (all P<0.05), and the NIHSS score and hematoma volume of the observation group were significantly lower than those of the control group (all P<0.05). In addition, the changes of NIHSS score and hematoma volume in the observation group before and after treatment were significantly greater than those in the control group ( P<0.01). In animal experiments, the hematoma volume in the breaking blood expelling stasis group on the 14th day after ICH was significantly smaller than that in the ICH group [(9.8±4.9)mm 3 vs (17.6±6.4)mm 3,P<0.05], and the reduction of hematoma in the breaking blood expelling stasis group on the 7th and 14th day was significantly larger than that in the ICH group [(4.6±2.9)mm 3 vs (-2.1±1.6)mm 3, (14.3±3.8)mm 3 vs (4.2±2.8)mm 3, all P<0.01]. The percentage of right turn on 3rd, 7th and 14th day and the modified Neurological Severity Score (mNSS) on 7th and 14th day in the breaking blood expelling stasis group were lower than those in the ICH group (all P<0.05). Western blot analysis showed that the expressions of CD11b, CD36 and PPARγ in the breaking blood expelling stasis group on the third day after ICH were significantly higher than those in the ICH group (CD11b: 0.78±0.12 vs 0.49±0.11, P<0.05; CD36: 1.16±0.16 vs 0.80±0.11, P<0.05; PPARγ: 0.78±0.11 vs 0.37±0.10, P<0.01). Conclusions:Breaking blood expelling stasis can effectively accelerate intracerebral hematoma clearance and improve neurological outcome after ICH, and the mechanism maybe probably mediated by activating PPARγ and enhanced CD36, CD11b upregulation on microglia/macrophages, which resulting in facilitating erythrocyte endogenous phagocytosis.

Oxygen Metabolism-induced Stress Response Underlies Heart-brain Interaction Governing Human Consciousness-breaking and Attention / 神经科学通报·英文版

Neuroscientists have emphasized visceral influences on consciousness and attention, but the potential neurophysiological pathways remain under exploration. Here, we found two neurophysiological pathways of heart-brain interaction based on the relationship between oxygen-transport by red blood cells (RBCs) and consciousness/attention. To this end, we collected a dataset based on the routine physical examination, the breaking continuous flash suppression (b-CFS) paradigm, and an attention network test (ANT) in 140 immigrants under the hypoxic Tibetan environment. We combined electroencephalography and multilevel mediation analysis to investigate the relationship between RBC properties and consciousness/attention. The results showed that RBC function, via two independent neurophysiological pathways, not only triggered interoceptive re-representations in the insula and awareness connected to orienting attention but also induced an immune response corresponding to consciousness and executive control. Importantly, consciousness played a fundamental role in executive function which might be associated with the level of perceived stress. These results indicated the important role of oxygen-transport in heart-brain interactions, in which the related stress response affected consciousness and executive control. The findings provide new insights into the neurophysiological schema of heart-brain interactions.

Simulação na educação médica: processo de construção de pacientes padronizados para comunicação de más notícias / Simulation in medical education: the process of standardized patient development for breaking bad news

Resumo: Introdução: Comunicação de más notícias refere-se às informações médicas que rompem de maneira adversa e negativa as expectativas de um paciente. Trata-se de um momento delicado da relação médico-paciente. O role playing com pacientes padronizados (PP) é uma alternativa para o ensino da comunicação, porém é desafiador construir roteiros e cenários semelhantes com a realidade, especialmente quando não se dispõe de atores profissionais. Objetivo: Este estudo teve como objetivo descrever a construção de PP a partir da experiência dos estudantes para o treinamento da comunicação com outros discentes de Medicina. Método: Estudantes de Medicina participaram voluntariamente da formação teatral e se dedicaram à construção de PP, com supervisão de docentes médicos e de atrizes, para oficinas de comunicação de más notícias. Para a construção dos PP, criaram-se diagnósticos médicos desfavoráveis, e estabeleceram-se os seguintes tópicos: perfil emocional, historicidade, instruções, progressões e possíveis desfechos, objetivos primário e secundário, e elementos facilitadores das cenas. Ensaiou-se exaustivamente para que os PP apresentassem a mesma reação em diferentes atitudes nas simulações. A participação nas oficinas foi aberta aos estudantes de Medicina interessados. Aferiu-se a qualidade das cenas pela sensação de realidade proporcionada aos participantes das oficinas. Resultado: Dez estudantes com idades entre 19 e 26 anos, de diferentes semestres, participaram do treinamento, do desenvolvimento de PP e das oficinas de simulação. Desenvolveram-se quatro cenas: Mariana recebeu diagnóstico de HIV e revelou violência sexual (60 cenas), Caroline e Marcelo receberam diagnóstico de câncer e necessidade de cirurgia (53 cenas), Thaís recebeu diagnóstico de insensibilidade androgênica e presença de gônadas masculinas (31 cenas), e Roger ou Rosana recebeu diagnóstico de retinose pigmentar e cegueira progressiva (22 cenas). Todos os PP proporcionaram sensação de realidade aos diferentes participantes das oficinas. Conclusão: Foi possível construir PP com estudantes de Medicina, apoiados por docentes, com a finalidade de participação em oficinas de comunicação de más notícias para outros discentes de Medicina que apontaram, em sua maioria, sensação de realidade com as cenas. Os estudantes atores se engajaram no processo e desenvolveram habilidades de comunicação e de empatia, características necessárias para a prática médica.

Abstract: Introduction: Breaking bad news is giving medical information that adversely and negatively disrupts a patient's expectations. This is a delicate moment in the doctor-patient relationship. Role playing with standardized patients (SP) is one method for teaching such communication skills, but it is challenging to construct scripts and scenarios that reflect reality, especially when professional actors are not used. Objective: To describe the construction of SP based on the students' experience for communication skills training with other medical students. Method: Medical students voluntarily participated in theatrical training, and worked on developing SPs, under the supervision of medical professors and actors, for breaking bad news workshops. For the construction of the SPs, unfavorable medical diagnoses were created, establishing an emotional profile, history, instructions, progressions and possible outcomes, primary and secondary objectives, and facilitating elements of the scenes. It was exhaustively tested so that the SP presented the same reaction in different attitudes in the simulations. Participation in the workshops was open to interested medical students. The quality of the scenes was measured by the sense of reality given to the workshop participants. Result: Ten students aged between 19 and 26 years, from different semesters, participated in the training, the SP development and role-play workshops. Four scenes were developed: Mariana was diagnosed with HIV and revealed sexual violence (60 scenes), Caroline and Marcelo who were diagnosed with cancer and needed surgery (53 scenes), Thais received a diagnosis of androgen insensitivity and presence of male gonads (31 scenes) and Roger or Rosana with retinitis pigmentosa and progressive blindness (22 scenes). All the SPs gave a sense of reality to the different workshop participants. Conclusion: It was possible to develop SPs with medical students, supported by professors, with the purpose of participating in workshops to communicate bad news to other medical students who perceived, for the most part, a sense of reality in the scenes. The student actors engaged in the process and developed communication and empathy competencies; characteristics necessary for medical practice.

A comparative study of extraction techniques for maximum recovery of bioactive compounds from Ganoderma lucidum spores / Estudio comparativo de técnicas de extracción para la máxima recuperación de compuestos bioactivos a partir esporas de Ganoderma lucidum

SUMMARY This study aimed at evaluating effective methods for breaking the hard and insoluble spores of Ganoderma lucidum to recover functional biomolecules. Rupture techniques were evaluated such as manual maceration (RM), maceration with spheres of various materials (BR), and microwave exposure plus maceration with steel/ chrome spheres (MBR1). Spore rupture was evaluated using UV-Vis spectroscopy, which showed vibrations of 2955, 1642, 1240, 1080 and 1746 cm-1 corresponding to changes in spore walls. The MBR1 extract contained the largest amounts of carbohydrates (19.80 mg.g-1 spores) and polyphenols (2.21 mg.g-1 spores), whereas the BR extract had higher antioxidant activity (57.22%Inb DPPH). The MBR1 and BR extracts contained 62.2 and 73.5% glucose, respectively. Both methods also involved significant extraction of carbohydrates and proteins. The best way to extract biomolecules from spore walls is to perform a microwave heat treatment and break the walls with steel/chrome spheres; this produces large quantities of carbohydrates with antioxidant properties.

RESUMEN El objetivo de este estudio fue evaluar varios métodos de ruptura de las esporas de Ganoderma lucidum y extraer sus propiedades bioactivas. Para este propósito se evaluaron diferentes técnicas de rompimiento como: la maceración manual (RM), la maceración con esferas de diversos materiales (BR) y la exposición a microondas junto la maceración de las esporas con esferas de acero/cromo (MBR1). La ruptura de las esporas fue evaluada por espectroscopia UV-Vis, la cual mostró que las vibraciones 2955, 1642, 1240, 1080 y 1746 cm-1 correspondieron a cambios estructurales en las paredes de las esporas. El extracto MBR1 presento el mayor contenido de carbohidratos (19,80 mg.g-1) y polifenoles (2,21 mg.g-1), mientras que el extracto BR tuvo una mayor actividad antioxidante (57,22% Inb DPPH). Los extractos MBR1 y BR también presentaron en el análisis de monosacáridos un 62,2 y 73,5% de contenido glucosa. Como conclusión la mejor metodología para extraer biomoléculas de las paredes de las esporas de G. lucidum fueron el tratamiento térmico con microondas y la ruptura de las paredes con esferas de acero/cromo, porque este proceso permitió la extracción de una mayor cantidad de carbohidratos con posibles propiedades antioxidantes.

Inverse arch roof breaking technique combined with pedicle screw and bone graft in the treatment of thoracolumbar burst fractures / 中国组织工程研究

BACKGROUND: The morbidity rate of thoracolumbar burst fracture is high; however, the simple posterior distraction and reduction technique has poor patient satisfaction on maintaining vertebral height and reducing complications. Therefore, we attempt to explore a better therapeutic regimen. OBJECTIVE: To assess the efficacy of inverse arch roof breaking technique combined with pedicle screw and bone graft in treatment of thoracolumbar burst fractures. METHODS: This was a retrospective study of 78 patients with thoracolumbar burst fractures. All the patients suffered from fresh closed fractures, and all of them were operated by posterior approach. The time from injury to surgery ranged from 4 to 14 days, with an average of 7.8 days. They were randomly assigned to two groups. The 38 cases in the simple distraction group were treated with simple vertebra pedicle screw-rod system distraction and reduction fixation. The 40 cases in the inverse arch roof breaking and bone graft group were treated with inverse arch roof breaking technique combined with pedicle screw and bone graft in fractured vertebra. All patients signed the informed consent. The study was approved by the Hospital Ethics Committee. Operation time, intraoperative blood loss, fracture healing time, anterior height ratio of injured vertebrae, Cobb angle, visual analogue score, Barthel Index and postoperative complications were measured between the two groups. RESULTS AND CONCLUSION: (1) The follow-up period for all patients was 10-22 months. (2) Operation time and intraoperative blood loss were better in the simple distraction group than in the inverse arch roof breaking and bone graft group (P < 0.01). (3) The ratio of anterior height of injured vertebra and Cobb angle were significantly different between the two groups (P < 0.01). Above indexes were better in the inverse arch roof breaking and bone graft group than in the simple distraction group. (4) There were significant differences in fracture healing time and life activity function (Barthel index) between the two groups (P < 0.01), and above indexes were better in the inverse arch roof breaking and bone graft group than in the simple distraction group. (5) No deep infection was found in both groups. There were no complications such as internal fixation failure and excessive loss of vertebral height in arch roof breaking and bone graft group. In the simple distraction group, there were 3 cases of screw pull-out because of failed internal fixation, 2 cases of titanium rod breakage, and 10 cases of obvious vertebral height loss. (6) These findings suggest that compared with simple distraction and reduction fixation, inverse arch roof breaking technique combined with pedicle screw and bone graft can provide bony support to compression center of fractured vertebra. The efficacy was identified in reconstructing the height of anterior and middle columns. This method has the advantages of high mechanical strength, strong vertebral height maintenance, high bone healing rate and few complications, which will be the ideal choice in the treatment of thoracolumbar burst fracture.

Habit-breaking methods employed by mothers of children with nonnutritive sucking habits resident in suburban Nigeria

Parents are often concerned about their children's nonnutritive sucking (NNS) habits and may institute mechanisms to try to break them. Aim: The study identified various methods instituted by mothers resident in a suburban Nigeria to break NNS habits of children, reasons for wanting to break the habit, and the association between instituted methods and sociodemographic profile of the mothers. Materials and Methods: The data of 129 mothers of children aged 4 years to 12 years who had NNS habits at the time of conducting a household survey were analyzed. Statistical Analysis: Tests of associations were conducted to determine the association between maternal age and level of education and methods employed to break child's NNS habits. Results: Eighty-four mothers (65.1%) made efforts to break the habit. Habit persisting to older age was the main concern. The most common method employed for breaking habits was punishing the child (54.8%).Only 7 (20.0%) mothers who were concerned about NNS habit(s) sought professional advice. A greater though insignificant percentage of mothers in the 25–34 years age group (57.2%; P = 0.48) and those with secondary school level of education (56.0%; P = 0.12) made efforts to break their children's NNS habits. Conclusions: The majority of mothers were concerned about their children's NNS habits. However, very few concerned mothers sought professional advice. Efforts need to be made to improve the public awareness about the availability of professional services for managing NNS habits and potential impact of employing nonprofessional methods to break habits.

The effect of breaking blood expelling stasis combined with edaravone on brain edema around hematoma and neurological function in patients with acute hypertensive intra-cerebral hemorrhage / 中国中西医结合急救杂志

Objective To observe the clinical effects of breaking blood expelling stasis method of traditional Chinese medicine (TCM) combined with edaravone on patients with acute hypertensive intra-cerebral hemorrhage and preliminarily discuss its protection mechanism on this disease. Methods Ninety-two patients with hypertensive intra-cerebral hemorrhage within 72 hours after occurrence admitted to Zengcheng District People's Hosipital of Guangzhou from May 2013 to December 2017 were enrolled, they were divided into conventional therapy group and combined treatment of TCM and western medicine group by random numbers produced by a computer, 46 cases in each group. The conventional therapy group was treated with conventional therapy, and the combined treatment of TCM and western medicine group was treated with conventional therapy, additionally the treatment of Poxue Zhuyu decoction (the ingredients of the decoction: leech 10 g, gradfly 10 g, rhubarb 15 g, cattail pollen 5 g, trichosanthes fruit 10 g, radix notoginseng 5 g, colla plastri testudinis 10 g, grassleaf sweetflag rhizome 10 g, ground beetle 3 g, dried lacquer 3 g, peach seed 10 g) and edaravone for 10 days. The levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in serum were tested by enzyme-linked immunosorbent assay (ELISA) before and 7 days after treatment in the two groups; and the differences in National Institutes of Health stroke scale score (NIHSS) before and 14 days, 90 days after treatment as well as the changes of brain edema around the hematoma 14 days after treatment were compared between the two groups, and the incidence of adverse reaction was observed. Results After treatment, the levels of TNF-α, IL-6 and intra-cerebral hemorrhage quantities in the two groups were all decreased compared with those before treatment, and the degrees of decrease of TNF-α and cerebral hemorrhage volume in combined treatment of TCM and western medicine group were more significant than those in the conventional treatment group [TNF-α (ng/L): 21.00±6.10 vs. 29.40±11.33, cerebral hemorrhage volume (mL): 5.23±0.60 vs. 8.50±0.64, both P <0.05]. The IL-6 in the two groups were recovered to approximately normal levels after the treatment (ng/L: 13.60±5.36 vs. 15.40±6.13, P > 0.05). With the prolongation of therapeutic time, the scores of NIHSS of the two groups were significantly lowered than those before treatment, and the degree of reduction in the combined TCM and western medicine group on 90 days after treatment was more obvious than that of the conventional treatment group (4.34±0.67 vs. 7.73±0.61, P < 0.05). The volumes of edema around hematomas were increased after treatment in the two groups, but the degree of increase in combined treatment of TCM and western medicine group was slower than that of the conventional group (cm3: 7.57±0.64 vs. 10.16±0.60, P < 0.05). There was no statistical significant difference in the incidence of adverse reactions in comparison between the combined treatment of TCM and western medicine group and conventional therapy group [18.2% (8/44) vs. 20.5% (9/44), P > 0.05]. Conclusions Using breaking blood expelling stasis and edaravone for treatment of acute hypertensive intra-cerebral hemorrhage can accelerate the absorption of brain hematoma and improve the neurological function, and its mechanism may be relevant to the inhibition of some inflammatory factors.

1, 25-dihidroxivitamina-D 3 sobre as características ósseas de frangos de corte fêmeas / 1, 25-dihydroxyvitamin-D3 over bony characteristics of female broilers

Objetivou-se avaliar as características dos tibiotarsos de frangos de corte fêmeas. As variáveis analisadas foram os pesos in natura, secos e desengordurados, o comprimento, os diâmetros, a resistência óssea, o índice de Seedor (IS), os percentuais de proteínas colagenosas (PC), as proteínas não colagenosas (PNC), os minerais (cálcio, fósforo, potássio e sódio) e as cinzas. Foram utilizadas 648 aves, da marca comercial Cobb®, em um delineamento em blocos ao acaso, com seis tratamentos e seis repetições, com 18 aves por unidade experimental. Os tratamentos consistiram na suplementação de 0,00; 0,50; 1,00; 1,50; 2,00 e 2,50 µg de 1,25-dihidroxivitamina-D3 (1,25(OH)2D3)/kg de ração. Aos 21 e 35 dias de idade, as aves foram pesadas e uma ave por unidade experimental (UE) com o peso médio da UE foi eutanasiada para a obtenção dos tibiotarsos e subsequente análise dos parâmetros ósseos. As variáveis métricas, bem como a composição orgânica (PC), a densidade (IS) e a resistência à quebra dos ossos das aves, não foram influenciadas pelos tratamentos. No recebimento de 2,50 µg de 1,25(OH)2D3/kg de ração, observou-se maior retenção mineral (cinzas) nos ossos das aves aos 35 dias de idade.(AU)

This study aimed to evaluate the characteristics of tibiotarsus of female broilers. The variables analyzed were the weights in natura, dry and degreased, length, diameter, bone strength, Seedor index, percentage of collagenous protein (CP), non-collagenous proteins (NCP), minerals (calcium, phosphorus, potassium and sodium), and ash. Six hundred forty-eight, Cobb® birds were used, a design of randomized blocks with six treatments and six replicates of 18 birds each. The treatments consisted of supplementation of 0.00; 0.50; 1.00; 1.50; 2.00 to 2.50 µg of 1,25-dihydroxyvitamin-D3 (1,25(OH)2D3)/kg of ration. At 21 and 35 days of age the birds were weighed and a unit/experimental unit (EU) with the EU average weight was euthanized to obtain the tibiotarsos and subsequent analysis of the bone parameters. The metric variables, as well as the organic composition (CP), density (IS) and resistance to breakage of the bones of the birds were not affected by treatments. Upon reception of 2.50 µg of 1,25(OH)2D3/kg ration, there was a higher mineral retention (ashes) in the bones of female broilers at 35 days of age.(AU)

Comunicação de más notícias em saúde: contribuições à discussão bioética através de uma nova ética das virtudes

Este trabalho compreende uma pesquisa teórica através de revisão bibliográfica narrativa. O objeto desta pesquisa foi a comunicação de más notícias em saúde, no âmbito da relação médico-paciente. Utilizando o instrumental teórico disponível no campo da Bioética, procurou-se responder à questão teórica acerca das contribuições possíveis de uma nova teoria ética baseada nas virtudes de caráter do agente moral para a discussão sobre comunicação de más notícias em saúde, e também para a própria Bioética. A teoria ética das virtudes da filósofa neozelandesa Christine Swanton, fundamentada a partir de conceitos importantes da filosofia de Nietzsche, mostrou-se útil quando aplicada ao debate ético na relação médico-paciente. Também foi possível utilizar esta formulação teórica na ponderação sobre a situação de comunicação de más notícias em saúde, a partir da articulação com um caso clínico discutido no âmbito da bioética. Por fim, a Ética das Virtudes Pluralista de Swanton demonstrou ser capaz de oferecer contribuições aos debates éticos no campo da Bioética, ratificando nossa hipótese inicial.

This work comprises a theoretical research through narrative bibliographic review. The object of this research was breaking bad news in health care, within the scope of the doctor-patient relationship. Using the theoretical tools available in the field of Bioethics, we sought to answer the theoretical question about the possible contributions of a new ethical theory based on the moral agent's character virtues to the discussion about breaking bad news in health care, and also to the own Bioethics. The ethical theory of virtues of the New Zealand philosopher Christine Swanton, grounded on important concepts of Nietzsche's philosophy, has proved useful when applied to the ethical debate in the doctor-patient relationship. It was also possible to use this theoretical formulation in the weighting on the situation of breaking of bad news in health care, based on the articulation with a clinical case discussed within bioethics scope. Finally, Swanton's Pluralistic Virtue Ethics proved to be able to offer contributions to ethical debates in the field of Bioethics, ratifying our initial hypothesis.
