RESUMO

ABSTRACT Whether in pre-pregnancy, pregnancy, birth and/or the postnatal and neonatal periods, midwives' practices are underpinned by humanism. However, in this era of postmodernity, there is an ever-growing need for rehumanization. This article adopts an auto-ethnographic approach in order to undertake a reflective analysis on the humanization of birth based on the practice of midwifery in two different contexts, namely Quebec (Canada) and Chile. In light of the evolution of the profession in these two countries, and the influence of health policies and social movements, there are factors such as the systematic use of technology and the hypermedicalization of reproductive processes which are maintaining women's ignorance and keeping them from being able to participate in their maternity process. Women's autonomy and empowerment become a key element for their participation in decisions regarding their maternity, assistance methods, or type of care. Concurrently, midwives' autonomy is a prerequisite for fully exercising their role in supporting and assisting women in this re-appropriation of their power by means of a comprehensive approach that takes into account psychological and social aspects as well as biomedical ones.


RESUMO Seja na pré-gravidez, na gravidez, no nascimento, seja nos períodos pós-natal e neonatal, as práticas das parteiras são sustentadas pelo humanismo. Entretanto, na atual era de pós-modernidade, há uma necessidade cada vez maior de reumanização. Este artigo adota uma abordagem autoetnográfica, a fim de realizar análise reflexiva sobre a humanização do nascimento baseada na prática da obstetrícia em dois contextos diferentes: Quebec (Canadá) e Chile. À luz da evolução da profissão nestes dois países e da influência das políticas de saúde e dos movimentos sociais, existem fatores, como o uso sistemático da tecnologia e a hipermedicalização dos processos reprodutivos, que estão mantendo as mulheres desinformadas e impedindo-as de participar de seu processo de maternidade. A autonomia e o empoderamento das mulheres tornam-se um elemento-chave para sua participação nas decisões relativas à sua maternidade, métodos de assistência ou tipo de cuidado. Ao mesmo tempo, a autonomia das parteiras é um requisito para o pleno exercício de seu papel de apoio e assistência às mulheres nesta reapropriação de seu poder, por meio de uma abordagem abrangente, que leve em conta tanto aspectos psicológicos e sociais quanto biomédicos.

RESUMO

OBJECTIVE: To explore women's representations of pregnancy and childbirth and how these representations are constructed and have changed. BACKGROUND: In the 1980s, many women in Quebec demanded that the birthing process be both demedicalised and humanised, resulting in the legalisation of the midwife profession while expanding their choices over birthing locations within the public health system (e.g., birthing centres, the home, or hospitals). Birth-related technologies were also improving at that time. Nearly 40 years later, we wanted to learn about their perceptions. METHOD: This qualitative and contextualised phenomenological study surveyed 25 first-time mothers who had received care from midwives, general practitioners, or obstetricians. Each participant met with the researcher twice during her pregnancy and once after giving birth to engage in narrative conversations, which were analysed from an interdisciplinary viewpoint (socio-anthropology). FINDINGS: Participant perceptions of pregnancy varied. Some saw it as a state that distorted the body, while others saw it as a long period of struggle with a compulsory step that was also fascinating and/or even happy. Women undergo an incremental process of change before contemplating childbirth, and typically undergo a transitional period when nearing the event itself. They may think of childbirth as joyful and/or painful. Representations are built intersubjectively through influences involving family, the media, and care providers. Stories from their mothers, therefore, created undeniable impressions. CONCLUSION: In a context heavily influenced by technology, easy pregnancies and/or childbirth events are typically deemed "lucky." This negatively reinforces both the cultural and intergenerational values transmitted regarding these events.

RESUMO

Medical interventions during childbirth are on the rise and many women in Quebec emerge from a first childbirth with the desire to live a different, less medicalized subsequent experience. To address how multiparity can affect the ways of giving birth, we conducted 20 in-depth qualitative interviews with multiparas who gave birth to their last child in various birthing environments in the 6 months prior to this study. Using tri-level coding, we inductively analyzed the transcripts, which showed an evolution in the participants' perspectives. A spiral effect seems to be in place: The more women feel at ease with childbirth, the more they seek to establish a context in which they feel even more at ease. However, some women had to go through multiple birth experiences before being able to assert themselves and consider their perspectives regarding their own experiences as legitimate.

RESUMO

OBJECTIVE: To review the evidence relating to nonpharmacological approaches in the management of pain during labour and delivery. To formulate recommendations for the usage of nonpharmacological approaches to pain management. OPTIONS: Nonpharmacological methods available for pain management during labour and delivery exist. These should be included in the counselling and care of women. EVIDENCE: PubMed and Medline were searched for articles in French and English on subjects related to "breastfeeding," "pain," "epidural," "anaesthesia," "analgesia," "labour," "labor," and combined with "gate control theory," "alternative therapies," "massage," "position," "mobility," "TENS," "bathing," "DNIC," "acupuncture," "acupressure," "sterile water injection," "higher center," "control mind," "cognitive structuring," "holistic health," "complementary therapy(ies)," "breathing," "relaxation," "mental imagery," "visualization," "mind focusing," "hypnosis," "auto-hypnosis," "sophrology," "mind and body interventions," "music," "odors," "biofeedback," "Lamaze," "Bonapace," "prenatal training," "gymnastic," "chanting," "haptonomy," "environment," "transcutaneous electrical stimulus-stimulation," "antenatal education," "support," "continuous support," "psychosocial support," "psychosomatic medicine," "supportive care," "companion," "intrapartum care," "nurse," "midwife(ves)," "father," "doula," "caregiver," " hormones," "oxytocin," "endorphin," "prolactin," "catecholamine," "adrenaline," and "noradrenaline" from 1990 to December 2015. Additional studies were identified by screening reference lists from selected studies and from expert suggestions. No language restrictions were applied. VALIDATION METHODS: The quality of the evidence is rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care. Recommendations for practice are ranked according to the method described in this report. BENEFITS, RISKS, AND COST: The nonpharmacological method encourages an incremental approach to pain management that contributes to reduced interventions through optimal use of the woman's neurophysiologic and endocrine resources and a better understanding of the physiology of stress and pain during labour. GUIDELINE UPDATE: The guideline will be reviewed 5 years after publication to decide whether all of part of the guideline should be updated. However, if important new evidence is published prior to the 5-year cycles, the review process may be accelerated for a more rapid update of some recommendations. SPONSORS: This guideline was developed with resources funded by The Society of Obstetricians and Gynaecologists of Canada. SUMMARY STATEMENTS: RECOMMENDATIONS.

RESUMO

Parents' decision to use vaccination services is complex and multi-factorial. Of particular interest are "vaccine-hesitant" parents who are in the middle of the continuum between vaccine acceptance and refusal. The objective of this qualitative longitudinal study was to better understand why mothers choose to vaccinate-or not-their newborns. Fifty-six pregnant mothers living in different areas of Quebec (Canada) were interviewed. These interviews gathered information on mothers' views about health and vaccination. Almost half of the mothers were categorized as vaccine-hesitant. A second interview was conducted with these mothers 3 to 11 months after birth to look at their actual decision and behavior concerning vaccination. Our results show the heterogeneity of factors influencing vaccine decision making. Although the majority of vaccine-hesitant mothers finally chose to follow the recommended vaccine schedule for their child, they were still ambivalent and they continued to question their decision.

RESUMO

Public health authorities have been alarmed by the progressive rise in rates of Caesarean section in Canada, approaching one birth in three in several provinces. We aimed therefore to consider what were preventable obstetrical interventions in women with a low-risk pregnancy and to propose an analytic framework for the reduction of the rate of CS. We obtained statistical variations of CS rates over time, across regions, and within professional practices from MED-ÉCHO, the Quebec hospitalization database, from 1969 to 2009. Data were extracted from a recent systematic review of the cascade of obstetrical interventions to calculate the population-attributable fractions for each intervention associated with an increased probability of CS. We thereby identified expectant management (as an alternative to labour induction) and planned vaginal birth after CS as the leading strategies for potentially reducing rates of CS in women at low risk. For vaginal birth after CS, an increase to its 1995 level could lower the current CS rate of 23.2% (2009 to 2010) to 21.0%. Other alternatives to obstetrical interventions with a potential for lowering CS rates included non-pharmacological pain control methods (such as continuous support during childbirth) in addition to usual care, intermittent auscultation of the fetal heart (instead of electronic fetal monitoring), and multidisciplinary internal quality assessment audits. We believe, therefore, that the concept of preventable CS is supported by empirical evidence, and we identified realistic strategies to maintain a CS rate in Quebec near 20%.


Les autorités en matière de santé publique ont été alarmées par la hausse graduelle des taux de césarienne (CS) au Canada (près d'une naissance sur trois dans plusieurs provinces). Nous avons donc cherché à identifier les interventions obstétricales qui pouvaient être évitées chez les femmes qui connaissent une grossesse les exposant à de faibles risques, ainsi qu'à proposer un cadre analytique pour la réduction du taux de CS. Les variations statistiques, entre 1969 et 2009, des taux de CS avec le temps, d'une région à l'autre et en fonction des pratiques professionnelles ont été tirées de MED-ÉCHO (la base de données sur l'hospitalisation au Québec). Des données ont été tirées d'une récente analyse systématique de la cascade d'interventions obstétricales en vue de calculer les fractions étiologiques du risque pour chacune des interventions associées à une probabilité accrue de CS. Nous avons ainsi identifié la prise en charge non interventionniste (à titre de solution de rechange au déclenchement du travail) et l'accouchement vaginal planifié après CS comme étant les principales stratégies pouvant permettre la réduction des taux de CS chez les femmes exposées à de faibles risques. Pour ce qui est de l'accouchement vaginal après CS, une hausse jusqu'à son niveau de 1995 pourrait faire passer le taux actuel de CS de 23,2 % (de 2009 à 2010) à 21,0 %. Parmi les solutions de rechange aux interventions obstétricales qui présentent le potentiel d'abaisser les taux de CS, on trouvait les méthodes non pharmacologiques de maîtrise de la douleur (comme l'offre d'un soutien continu pendant l'accouchement) s'ajoutant aux soins habituels, l'auscultation intermittente du cœur fœtal (plutôt que le monitorage électronique du fœtus) et les audits internes multidisciplinaires de la qualité. Nous estimons donc que le concept de la CS évitable est soutenu par des données empiriques et nous avons identifié des stratégies réalistes permettant d'assurer le maintien, au Québec, d'un taux de CS se situant près de 20 %.

RESUMO

Even if vaccination is often described as one of the great achievements of public health, results of recent studies have shown that parental acceptance of vaccination is eroding. Health providers' knowledge and attitudes about vaccines are important determinants of their own vaccine uptake, their intention to recommend vaccines to patients and the vaccine uptake of their patients. The purpose of this article is to compare how midwives and physicians address vaccination with parents during pregnancy and in postpartum visits. Thirty semi-structured interviews were conducted with midwives and physicians practicing in the province of Quebec, Canada. Results of our analysis have shown that physicians adopt an "education-information" stance when discussing vaccination with parents in the attempt to "convince" parents to vaccinate. In contrast, midwives adopted a neutral stance and gave information on the pros and cons of vaccination to parents while leaving the final decision up to them. Findings of this study highlight the fact that physicians and midwives have different views regarding their role and responsibilities concerning vaccination. It may be that neither of these approaches is optimal in promoting vaccination uptake.

RESUMO

OBJECTIVE: To learn the adaptations and transformations that midwives from abroad must go through in order to integrate into the practice of Quebec midwifery, which is founded on a concept of birth akin to the holistic model. DESIGN: Qualitative research achieved through semi-structured interviews with an ethnological approach for data collection and analysis. SETTING: Quebec, Canada. PARTICIPANTS: 11 immigrant midwives practising in Quebec. Interviews were also conducted with midwives from Quebec trained abroad (3) and trained in Quebec (5). FINDINGS: The greatest challenge for most of the midwives interviewed has been the change of professional culture. Shifting from a technocratic or medical practice model towards a holistic practice model has expanded their points of reference. Medical knowledge has become a type of shared knowledge, with each contributor judged equally important. Nature and humanity now prevail over technology. The woman has become the primary reference source for decision-making. For some midwives of foreign origin, integration into the Quebec practice provided an opportunity to reflect upon or modify their perception of pregnancy. In terms of representations, although most of the midwives interviewed now consider childbirth a life-affirming experience; for others, it represents a potential risk of complications or catastrophes. This apprehensiveness is more significant among midwives who have been trained in a medical model and who come from a country where the medical culture is socially dominant. KEY CONCLUSIONS: Midwives from highly medicalized environments face a greater adjustment when integrating into Quebec's practice culture. They must shift from a 'risk' mindset to a 'confidence' mindset and develop their trust in the normal process of pregnancy and childbirth. They must acquire a sense of inner security on which they can rely instead of systematically resorting to technological referents. This adjustment of referents and representations is an operative transformation process that is often accompanied by changes in identity. IMPLICATIONS FOR PRACTICE: To facilitate the integration of immigrant midwives, it is important to consider the professional culture changes they face. If they are to use a holistic practice model, they must engage in introspection. They must reflect on pregnancy and childbirth if they are to consider these events first and foremost as a healthy, integral part of women's lives.

RESUMO

A 40-year old man is evaluated for arterial hypertension of one's year duration, which responded well to salt restriction and mild antihypertensive medication. The standard investigation for possible secondary hypertension is negative. In view of a remote history of left renal trauma, it is decided to do an angiogram, which reveals the presence of a fractured left kidney. This unusual image is considered to be secondary to the combination of an arterial supply provided by two polar arteries and of scarring in the mid-portion of the renal parenchyma secondary to the remote trauma.

RESUMO

We previously demonstrated that erythropoietin (EPO)-secreting mesenchymal stromal cells (MSC) can be used for the long-term correction of renal failure-induced anemia. The present study provides evidence that coimplantation of insulin-like growth factor I (IGF-I)-overexpressing MSC (MSC-IGF) improves MSC-based gene therapy of anemia by providing paracrine support to EPO-secreting MSC (MSC-EPO) within a subcutaneous implant. IGF-I receptor RNA expression in murine MSC was demonstrated by RT-PCR. Functional protein expression was confirmed by immunoblots and MSC responsiveness to IGF-I stimulation in vitro. IGF-I was also shown to improve MSC survival following staurosporin-induced apoptosis in vitro. A cohort of C57Bl/6 mice was rendered anemic by right kidney electrocoagulation and left nephrectomy. MSC-EPO were subsequently admixed in a bovine collagen matrix and implanted, in combination with MSC-IGF or MSC null, by subcutaneous injection in renal failure mice. In mice receiving MSC-EPO coimplanted with MSC-IGF, hematocrit elevation was greater and enhanced compared with control mice; heart function was also improved. MSC-IGF coimplantation, therefore, represents a promising new strategy for enhancing MSC survival within implanted matrices and for improving cell-based gene therapy of renal anemia.

RESUMO

Limited data are available regarding the optimal management of renal artery stenosis (RAS) with a coexisting renal artery aneurysm. We present a case of high-grade RAS treated successfully with a stent-graft deployment resulting in the exclusion of an associated aneurysm. This therapeutic approach induced the sustained normalization of the blood pressure without antihypertensive medication and the correction of biochemical abnormalities secondary to the RAS.

RESUMO

Indinavir, used for the treatment of HIV disease, forms distinctive crystals in the urine. The crystalluria has been associated principally with several urinary tract abnormalities which may require discontinuation of the drug. We present a case of progressive leucocyturia and renal impairment occurring during indinavir treatment which illustrates vividly the impact of the crystalluria on the tubulointerstitial renal compartment.

RESUMO

The goal of this research was to develop a strategy to couple stem cell and gene therapy for in vivo delivery of erythropoietin (Epo) for treatment of anemia of ESRD. It was shown previously that autologous bone marrow stromal cells (MSCs) can be genetically engineered to secrete pharmacologic amounts of Epo in normal mice. Therefore, whether anemia in mice with mild to moderate chronic renal failure (CRF) can be improved with Epo gene-modified MSCs (Epo+MSCs) within a subcutaneous implant was examined. A cohort of C57BL/6 mice were rendered anemic by right kidney electrocoagulation and left nephrectomy. In these CRF mice, the hematocrit (Hct) dropped from a prenephrectomy baseline of approximately 55% to 40% after induction of renal failure. MSCs from C57BL/6 donor mice were genetically engineered to secrete murine Epo at a rate of 3 to 4 units of Epo/10(6) cells per 24 h, embedded in a collagen-based matrix, and implanted subcutaneously in anemic CRF mice. It was observed that Hct increased after administration of Epo+MSCs, according to cell dose. Implants of 3 million Epo+MSCs per mouse had no effect on Hct, whereas 10 million led to a supraphysiologic effect. The Hct of CRF mice that received 4.5 or 7.5 million Epo+MSCs rose to a peak 54+/-4.0 or 63+/-5.5%, respectively, at 3 wk after implantation and remained above 48 or 54% for >19 wk. Moreover, mice that had CRF and received Epo+MSCs showed significantly greater swimming exercise capacity. In conclusion, these results demonstrate that subcutaneous implantation of Epo-secreting genetically engineered MSCs can correct anemia that occurs in a murine model of CRF.

RESUMO

Since 1998, there has been a marked increase in incidence of pure red cell aplasia secondary to development of anti-erythropoietin antibodies (Ab+ PRCA) in patients who have chronic kidney disease (CKD) and receive recombinant erythropoietin. The relationship between incidence of Ab+ PRCA and specific erythropoietin products has not been examined rigorously. Manufacturers provided data regarding exposure to erythropoietin products and incidence of Ab+ PRCA between January 1998 and March 2003 in patients with CKD. Assuming a Poisson distribution, a maximum likelihood estimate for the Poisson rate parameter was calculated for each product. A test for homogeneity of Poisson rates was conducted to compare likelihood estimates between products. Global incidence of Ab+ PRCA was relatively low. Likelihood estimates were not significantly different for Epogen, Procrit, and Aranesp, independent of their formulation or route of administration. Eprex lacking human serum albumin (HSA) and administered subcutaneously was associated with the greatest risk of Ab+ PRCA. HSA-containing Eprex administered subcutaneously was associated with a lower risk than HSA-free Eprex administered subcutaneously, but this risk exceeded that of intravenous Epogen and intravenous HSA-free Eprex. NeoRecormon administered subcutaneously was associated with less risk than subcutaneous HSA-free Eprex but more risk than intravenous Epogen. HSA-free Eprex should not be administered subcutaneously to patients with CKD due to increased risk of Ab+ PRCA. Although the subcutaneous administration of HSA-containing Eprex is riskier than intravenous Epogen and intravenous HSA-free Eprex, and the use of subcutaneous NeoRecormon is riskier than intravenous Epogen, there is currently no evidence that other products are safer.

RESUMO

Hydrothorax, an uncommon complication of peritoneal dialysis (PD), results from the migration of dialysis fluid under pressure from the peritoneal cavity into the pleural space. The exact site of the transdiaphragmatic fluid leak remains obscure, but the right-sided predominance of the hydrothorax points to the presence of abnormalities in the right hemidiaphragm. Such abnormalities have occasionally been described. In a recent case of acute massive right hydrothorax at the start of PD, the autopsy revealed extensive changes of amyloidosis that were comparable in both hemidiaphragms, prompting us to revisit the accepted explanation for right hydrothorax. We propose that an embryonic remnant--namely, the persisting pneumatoenteric recess and the infracardiac bursa--provides a passage connecting the peritoneal cavity to the right pleural space. The potential presence of this mechanism is consistent with the recognized clinical features of right hydrothorax complicating PD. This proposed route for dialysis fluid to form a right hydrothorax during PD can be investigated by currently available high-definition imaging techniques. This novel mechanism may also be involved in the pathogenesis of right hydrothorax observed in other medical conditions with tense ascites (liver cirrhosis, Meigs syndrome).

RESUMO

The C57BL/6 inbred mouse strain is known for its strong, genetically determined preference for alcohol over water. In this study we examined the voluntary alcohol consumption (VAC) of C57BL/6 mice during chronic renal failure (CRF). Two weeks after the surgical induction of renal failure, CRF mice, together with normal and sham-operated control mice, were submitted to a standard 24-day VAC protocol. The mice were offered water for the first 6 days (period of acclimatization), alcohol (10% ethanol solution) for the next 4 days (period of forced alcohol exposure), and a choice between water and alcohol for the last 14 days (VAC period). The results (mean +/- SEM) obtained from the last 8 days of the VAC period were significantly different (P <.05) between CRF mice and the 2 control groups. As expected, CRF mice had a higher total fluid intake than did normal and sham-operated controls (9.5 +/- 0.2 vs 5.4 +/- 0.2 and 5.4 +/- 0.2 g/d). Surprisingly, despite their increased total fluid consumption, CRF mice nearly abolished their absolute alcohol intake compared with that of both control groups (3.2 +/- 0.5 vs 13.1 +/- 0.8 and 14.2 +/- 1.1 g alcohol/kg body wt/d). The resulting alcohol preference ratio (g alcohol/g total fluid) was markedly decreased in the CRF mice compared with that in both control groups (0.09 +/- 0.01 vs 0.62 +/- 0.03 and 0.64 +/- 0.05). We conclude that the innate alcohol preference of C57BL/6 mice is nearly abolished during CRF. Additional studies to clarify the mechanism of this striking change in drinking pattern are required, with special emphasis on the possible role of angiotensin II, which is involved in thirst regulation and known to reduce the alcohol consumption of normal alcohol-preferring rats.
