The use of Complementary and Alternative Medicine in pregnancy: Data from the Avon Longitudinal Study of Parents and Children (ALSPAC)

Objectives - To report the frequency of Complementary and Alternative Medicine (CAM) use by a population of pregnant women in the UK. Design - Four postal self-completion questionnaires completed at 8, 12, 18 and 32 weeks’ gestation provided the source of CAMs used. Questions asked for written descriptions about the use of any treatments, pills, medicines, ointments, homeopathic medicines, herbal medicines, supplements, drinks and herbal teas. Setting - An observational, population-based, cohort study of parents and children of 14,541 pregnant women residing within the former county of Avon in south-west England. Data was available for 14,115 women. Results - Over a quarter (26.7%; n = 3774) of women had used a CAM at least once in pregnancy, the use rising from 6% in the 1st trimester to 12.4% in the 2nd to 26.3% in the 3rd. Herbal teas were the most commonly reported CAM at any time in pregnancy (17.7%; n = 2499) followed by homeopathic medicine (14.4%; n = 2038) and then herbal medicine (5.8%; n = 813). The most commonly used herbal product was chamomile used by 14.6% of women, the most commonly used homeopathic product was Arnica used by 3.1% of women. Other CAMs (osteopathy, aromatherapy, acupuncture/acupressure, Chinese herbal medicine, chiropractic, cranial sacral therapy, hypnosis, non-specific massage and reflexology) accounted for less than 1% of users. Conclusions - CAM use in pregnancy, where a wide range of CAMs has been assessed, has not been widely reported. Studies that have been conducted report varying results to this study (26.7%) by between 13.3% and 87% of pregnant women. Survey results will be affected by a number of factors namely the inclusion/exclusion of vitamins and minerals, the timing of data collection, the country of source, the number of women surveyed, and the different selection criteria of either recruiting women to the study or of categorising and identifying a CAM treatment or product

Women’s beliefs about medicines and adherence to pharmacotherapy in pregnancy: Opportunities for community pharmacists?

Background During pregnancy women might weigh benefits of treatment against potential risks to the unborn child. However, non-adherence to necessary treatment can adversely affect both mother and child. To optimize pregnant women’s beliefs and medication adherence, community pharmacists are ideally positioned to play an important role in primary care. Objective This narrative review aimed to summarize the evidence on 1) pregnant women’s beliefs, 2) medication adherence in pregnancy, and 3) community pharmacists’ counselling during pregnancy. Method Three search strategies were used in Medline and Embase to find original studies evaluating women’s beliefs, medication adherence and community pharmacists’ counselling during pregnancy. All original descriptive and analytic epidemiological studies performed in Europe, North America and Australia, written in English and published from 2000 onwards were included. Results We included 14 studies reporting on women’s beliefs, 11 studies on medication adherence and 9 on community pharmacists’ counselling during pregnancy. Women are more reluctant to use medicines during pregnancy and tend to overestimate the teratogenic risk of medicines. Risk perception varies with type of medicine, level of health literacy, education level and occupation. Furthermore, low medication adherence during pregnancy is common. Finally, limited evidence showed current community pharmacists’ counselling is insufficient. Barriers hindering pharmacists are insufficient knowledge and limited access to reliable information. Conclusion Concerns about medication use and non-adherence are widespread among pregnant women. Community pharmacists’ counselling during pregnancy is insufficient. Further education, training and research are required to support community pharmacists in fulfilling all the opportunities they have when counselling pregnant women

Communication and mutual resource exchange in north Florida hermit crabs

The patterns of shell exchange in three species of hermit crabs which overlap in distribution and shell use were observed in the laboratory. Crabs showed no tendency to initiate more exchanges with conspecifics as compared with nonconspecific individuals and there were no specific size dominance effects. Lack of common communicatory patterns between Clibararius vittatus and Pagurus pollicaris was correlated with minimal actual exchange, while Pagurus impressus exchanged with both species and executed patterns in common with both. The pattern of shell exchanges and preferences indicated that, in some cases, both individuals may gain in interspecific exchanges.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46904/1/265_2004_Article_BF00569198.pd

Interação entre células do cumulus e atividade da proteína quinase C em diferentes fases da maturação nuclear de oócitos bovinos Interaction between cumulus cells and the activity of protein kinase C at different stages of bovine oocyte nuclear maturation

Verificou-se a influência da proteína quinase C (PK-C) no reinício e na progressão da meiose em oócitos bovinos, determinando se as células do cumulus são mediadoras da PK-C na regulação da maturação dos oócitos. Complexos cumulus-oócitos (CCO) e oócitos desnudos (OD), distribuídos aleatoriamente em seis tratamentos (T) com base na presença de um ativador da PK-C (PMA) (T1 e T2), de um forbol éster incapaz de ativar a PK-C (4alfa-PDD-controle) (T3 e T4) ou de apenas o meio básico (TCM-199-controle) (T5 e T6), foram cultivados por 7, 9, 12, 18 e 22 horas. A percentagem de rompimento da vesícula germinativa no grupo cultivado com PMA foi maior do que nos dois grupos controle, com e sem células do cumulus. O cultivo de CCO e OD por 12 e 18 horas demonstrou que a PK-C influencia a progressão para os estádios de metáfase I (MI) e metáfase II (MII) de maneira dependente das células do cumulus. Nos períodos de 9 e 22 horas, não foi possível observar diferença entre os grupos quanto aos diferentes estádios de maturação. A ativação da PK-C acelera o reinício da meiose independentemente das células somáticas e acelera a progressão até os estádios de MI e MII na dependência das células do cumulus.<br>The aim of this study was to evaluate the effect of protein kinase C (PK-C) on the meiotic resumption and progression in bovine oocyte, and to determine if the cumulus cells mediate the PK-C action in the regulation of bovine oocyte nuclear maturation. Cumulus-oocyte complexes (COC) and denuded oocytes (DO), randomly allotted to 6 treatments (T) based on the presence of an activator of PK-C (PMA) (T1 and T2), or a phorbol ester unable to activate PK-C (4alphaPDD-control) (T3 and T4) or a basic culture medium (T5 and T6), were cultivated for 7, 9, 12, 18 and 22 hours. The percentage of germinal vesicle breakdown (GVBD) was higher when the oocytes were cultured with PMA than in the control groups with and without cumulus cells. However, PK-C was dependent of cumulus cells to affect the progression to the stages of metaphase I (MI) and metaphase II (MII) at 12 and 18 hours of culture. At 9 and 22 hours, no difference among groups was detected. PK-C accelerates the meiotic resumption independently of the somatic cells but depends on cumulus cells for the progression to the stages of MI and MII

Dinâmica do carbono da biomassa microbiana em cinco épocas do ano em diferentes sistemas de manejo do solo no cerrado Microbial biomass carbon dynamics in different soil management systems in the cerrado

Em um Latossolo Vermelho argiloso, na Embrapa Cerrados, em Planaltina, Distrito Federal, foram selecionadas uma área com vegetação de Cerrado (CE) e seis parcelas de um experimento de longa duração (20 anos): arado de discos pré-plantio (ADPP); arado de discos pós-colheita (ADPC); plantio direto a partir do segundo ano em área preparada com arado de discos em 1979, primeiro ano de cultivo (PDAD); arado de aivecas pré-plantio (AVPP); arado de aivecas pós-colheita (AVPC); e plantio direto a partir do segundo ano em área preparada com arado de aivecas em 1979, primeiro ano de cultivo (PDAV). Foram estimados o carbono da biomassa microbiana e o carbono orgânico do solo (Csolo) em cinco profundidades: 0-5, 5-10, 10-20, 20-30 e 30-40 cm; e em cinco épocas do ano: na época da colheita da soja (abril/2000); no final do período chuvoso, após aração pós-colheita da soja (maio/2000); no período seco, sem nenhuma cultura no campo (agosto/2000); no início do período chuvoso, no plantio do milho (novembro/2000); e na floração da cultura do milho (fevereiro/2001). Considerando todo o período de estudo, os teores de C da biomassa microbiana (Cmic) e de Csolo foram menores nas camadas mais profundas em todos os sistemas de manejo e no Cerrado. No solo sob sistema plantio direto, os teores de Cmic e Csolo decresceram das camadas mais superficiais para as mais profundas e de forma mais acentuada que no solo sob sistemas convencionais. No CE, a biomassa microbiana constituiu-se em maior percentagem do carbono orgânico total do solo, em comparação aos sistemas cultivados, que não apresentaram diferenças entre si.<br>Microbial biomass carbon and organic carbon were measured in a long-term field experiment (20 years) in Planaltina, DF, Brazil, under corn-soybean crop rotation. Six management systems were selected: disk plow before planting (ADPP); disk plow after harvesting (ADPC), no-till after disk plowing in the first year (PDAD); moldboard plow before planting (AVPP); moldboard plow after harvesting (AVPC), no-till after moldboard plowing in the first year (PDAV) and an undisturbed area of Savanna type vegetation, Cerrado (CE) as a reference. Soil samples were collected five times a year: 1- April, at soybean harvesting; 2- May, after soybean harvesting; 3- August, in the dry season with no crop on the field; 4- November, in the beginning rainfall season, at corn planting; 5- February, at corn tasseling. The samples were taken from five depths: 0-5, 5-10, 10-20, 20-30 and 30-40 cm of a clayey Red Latosol (Oxisol). Considering the whole study period, soil microbial carbon (Cmic) and soil organic carbon (Csoil) concentration were lower as soil profile depth increased for all management systems as well as in the Cerrado. Cmic and Csoil decreases under no-till system from superficial layers to the deeper ones were more pronounced than in the conventional systems. In the Cerrado, the microbial biomass represented a higher percentage of the total soil organic carbon in comparison to the management systems; there was no difference between conventional and no-till systems
