RESUMEN

OBJECTIVE: To present the development of a training model called AMBAR (Atención a la mujer embarazada y al recién nacido [Care for pregnant women and newborns]), which was designed to improve the quality of attention of health personnel responsible for obstetric care. MATERIALS AND METHODS: AMBAR was designed based on the results of a qualitative study exploring public health providers' needs and experiences. It was implemented in three health networks, and a total of 339 health personnel participated. RESULTS: The educational design of the course was appealing to the trained personnel, and the inclusion of simulations in all modules encouraged interest, participation, as well as the integration of new knowledge and skills into practice. CONCLUSION: AMBAR can promote better practices and increase the quality of birth care. With the proper support and willingness of staff and management, AMBAR can be implemented in all health services, both public and private.

RESUMEN

OBJECTIVES: To compare the risk of severe adverse maternal outcomes (SMO) and neonatal outcomes (SNO) and analyse their maternal correlates in adolescent mother-newborn and young mother-newborn dyads in secondary and tertiary care users in Latin America. METHODS: We performed a secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health database in 83 secondary and tertiary hospitals in seven countries in Latin America. We constructed a composite indicator of both SMO and SNO and estimated odds ratios (OR) comparing adolescent mothers (aged 12-19) with young mothers (aged 20-24). Our unit of analysis was the mother-newborn dyad. RESULTS: We found that the combination of SMO and SNO was three times more likely in adolescent mother as compared to young mother dyads (OR 3.56; 95% CI 1.67-7.59). SNO either alone or in combination with SMO were more likely in adolescents aged 12 to 16 than in young women (OR 1.27 and 4.87, respectively). CONCLUSIONS FOR PRACTICE: Adolescent mothers and their newborns are at an increased risk of severe adverse outcomes during child birth and in the first week postpartum compared to young mother dyads, especially young adolescents. Focusing on the dyad as a whole may facilitate a step towards integrated care which maximizes the health benefits of both mother and newborn. Continued efforts are needed to improve health care and prevention initiatives directed towards adolescent women and their newborns in Latin America.

RESUMEN

BACKGROUND: Pollen food allergy syndrome (PFAS) is a frequently underdiagnosed disease due to diverse triggers, clinical presentations, and test results. This is especially relevant in geographic areas with a broad spectrum of pollen sensitization, such as Southern Europe. OBJECTIVES: To elucidate similarities and differences of PFAS in nine Southern European centers and identify associated characteristics and unique markers of PFAS. METHODS: As part of the @IT.2020 Multicenter Study, 815 patients with seasonal allergic rhinitis (SAR), aged 10-60 years, were recruited in seven countries. They completed questionnaires regarding SAR, comorbidities, family history, and PFAS, and underwent skin prick testing (SPT) and serum IgE testing. RESULTS: Of the 815 patients, 167 (20.5%) reported PFAS reactions. Most commonly, eliciting foods were kiwi (58, 34.7%), peach (43, 25.7%), and melon (26, 15.6%). Reported reactions were mostly local (216/319, 67.7%), occurring within 5 min of contact with elicitors (209/319, 65.5%). Associated characteristics included positive IgE to at least one panallergen (profilin, PR-10, or nsLTP) (p = 0.007), maternal PFAS (OR: 3.716, p = 0.026), and asthma (OR: 1.752, p = 0.073). Between centers, heterogeneity in prevalence (Marseille: 7.5% vs. Rome: 41.4%, p < 0.001) and of clinical characteristics was apparent. Cypress played a limited role, with only 1/22 SPT mono-sensitized patients reporting a food reaction (p < 0.073). CONCLUSIONS: PFAS is a frequent comorbidity in Southern European SAR patients. Significant heterogeneity of clinical characteristics in PFAS patients among the centers was observed and may be related to the different pollen sensitization patterns in each geographic area. IgE to panallergen(s), maternal PFAS, and asthma could be PFAS-associated characteristics.

RESUMEN

BACKGROUND: The adequate definition of pollen seasons is essential to facilitate a correct diagnosis, treatment choice, and outcome assessment in patients with seasonal allergic rhinitis. A position paper by the European Academy of Allergy and Clinical Immunology (EAACI) proposed season definitions for Northern and Middle Europe. OBJECTIVE: To test the pollen season definitions proposed by EAACI in six Mediterranean cities for seven pollen taxa. METHODS: As part of the @IT.2020 multi-center study, pollen counts for Poaceae, Oleaceae, Fagales, Cupressaceae, Urticaceae (Parietaria spp.), and Compositae (Ambrosia spp., Artemisia spp.) were collected from January 1 to December 31, 2018. Based on these data, pollen seasons were identified according to EAACI criteria. A unified monitoring period for patients in AIT trials was created and assessed for feasibility. RESULTS: The analysis revealed a great heterogeneity between the different locations in terms of pattern and length of the examined pollen seasons. Further, we found a fragmentation of pollen seasons in several segments (max. 8) separated by periods of low pollen counts (intercurrent periods). Potential monitoring periods included often many recording days with low pollen exposure (max. 341 days). CONCLUSION: The Mediterranean climate leads to challenging pollen exposure times. Monitoring periods for AIT trials based on existing definitions may include many intermittent days with low pollen concentrations. Therefore, it is necessary to find an adapted pollen season definition as individual solution for each pollen and geographical area.

RESUMEN

BACKGROUND: Continuing education is essential for healthcare workers. Education interventions can help to maintain and improve competency and confidence in the technical skills necessary to address adverse events. However, characteristics of the health provider such as age (related to more critical and reflexive attitude); sex (relationship with gender socialization), profession and work conditions might have an influence on the effect of continuing education efforts. METHODS: A training in the management of obstetric and neonatal emergencies (PRONTO, Spanish acronym for Neonatal and Obstetric Rescue Program: Optimal and Timely treatment) was implemented in 14 hospitals in six Mexican states between 2013 and 2014, with a before-after evaluation design. A total of 351 health providers including physicians, interns, nurses and midwives completed the training and were included in the analytic sample. Mixed-effects regression models were fitted to model changes in knowledge and self-efficacy scores after the training for each training topic. Interaction terms of training with age, gender, profession, and shift were included to evaluate possible heterogeneities of effect. All models considered the within-hospital clustering of participants. RESULTS: After training, all participants showed a significant knowledge gain by an average of 19 percentage points for hemorrhage, 23 for neonatal resuscitation, 19 for shoulder dystocia, and 15 for preeclampsia/eclampsia (p < 0.001). Participants who worked night shifts showed lower scores for overall knowledge, compared with morning shift workers. Interns perceived the lowest self-efficacy while they scored very high in knowledge. Self-efficacy in managing obstetric and neonatal emergencies increased significantly by 16 percentage points in average. CONCLUSIONS: Our results show that PRONTO is generally successful in increasing knowledge and self-efficacy on all topics but knowledge and self efficacy levels vary greatly by factors such as work shift. Training should be particularly aimed at personnel working during weekends and night shifts, as well as interns and nurses.

RESUMEN

Important developments in chemotherapy for metastatic colorectal cancer over the last years are reviewed, with an emphasis on the most recently published data from clinical trials. The systematic review of current literature was conducted involving Pubmed Central® research and full articles were obtained and analyzed when appropriate. Fluorouracil still constitutes the backbone of metastatic colorectal cancer treatment; fluorouracil combination plus either irinotecan (FOLFIRI), oxaliplatin (FOLFOX) or capecitabine (CAPOX or XELOX) are chemotherapy protocols established as treatments producing similar outcomes. Actual treatment involves these chemotherapy protocols in combination with new molecular targeted drugs: bevacizumab and aflibercept (anti-vascular endothelial growth factor monoclonal antibody) and cetuximab and panitumumab (anti-epidermal growth factor receptor monoclonal antibody for patients with wild type KRAS) which confer significant survival benefits in select patients as first- or second-line therapies. The factors affecting the decisions for one treatment over other are related to the patient and toxicity drug. Finally, metastatic colorectal cancer patients progressing after all standard therapies (maintaining a good ECOG performance status) could be candidates for further therapies such as regorafenib and TAS-102. Regarding the future, promising therapies are under development for the metastatic colorectal cancer treatment and several agents are currently being evaluated in different clinical trials.

RESUMEN

AIMS: To determine risk factors for active tuberculosis in patients with inflammatory bowel diseases. METHODS: Retrospective, case-control study at 4 referral hospitals in Spain. Cases developed tuberculosis after a diagnosis of inflammatory bowel disease. Controls were inflammatory bowel disease patients who did not develop tuberculosis. For each case, we randomly selected 3 controls matched for sex, age (within 5 years) and time of inflammatory bowel disease diagnosis (within 3 years). Inflammatory bowel disease characteristics, candidate risk factors for tuberculosis and information about the tuberculosis episode were recorded. Multivariate analysis and a Chi-squared automatic interaction detector were used. RESULTS: Thirty-four cases and 102 controls were included. Nine of the 34 cases developed active tuberculosis between 1989 and 1999, and 25 became ill between 2000 and 2012. Multivariate regression showed an association between active tuberculosis and anti-TNF (tumor necrosis factor) therapy in the previous 12 months (OR 7.45; 95% CI, 2.39-23.12; p = .001); hospitalization in the previous 6 months (OR 4.38; 95% CI, 1.18-16.20; p = .027); and albumin levels (OR 0.88; 95% CI, 0.81-0.95; p = .001). The median time between the start of biologic therapy and the onset of active tuberculosis was 13 (interquartile range, 1-58) months. Tuberculosis developed after a year of anti-TNF therapy in 53%, and late reactivation occurred in at least 3 of 8 patients. CONCLUSIONS: The main risks factors for developing tuberculosis were anti-TNF therapy and hospitalization. Over half the cases related to anti-TNF treatment occurred after a year.

RESUMEN

The Spanish Myeloma Group conducted a trial to compare bortezomib/thalidomide/dexamethasone (VTD) versus thalidomide/dexamethasone (TD) versus vincristine, BCNU, melphalan, cyclophosphamide, prednisone/vincristine, BCNU, doxorubicin, dexamethasone/bortezomib (VBMCP/VBAD/B) in patients aged 65 years or younger with multiple myeloma. The primary endpoint was complete response (CR) rate postinduction and post-autologous stem cell transplantation (ASCT). Three hundred eighty-six patients were allocated to VTD (130), TD (127), or VBMCP/VBAD/B (129). The CR rate was significantly higher with VTD than with TD (35% vs 14%, P = .001) or with VBMCP/VBAD/B (35% vs 21%, P = .01). The median progression-free survival (PFS) was significantly longer with VTD (56.2 vs 28.2 vs 35.5 months, P = .01). In an intention-to-treat analysis, the post-ASCT CR rate was higher with VTD than with TD (46% vs 24%, P = .004) or with VBMCP/VBAD/B (46% vs 38%, P = .1). Patients with high-risk cytogenetics had a shorter PFS and overall survival in the overall series and in all treatment groups. In conclusion, VTD resulted in a higher pre- and posttransplantation CR rate and in a significantly longer PFS although it was not able to overcome the poor prognosis of high-risk cytogenetics. Our results support the use of VTD as a highly effective induction regimen prior to ASCT. The study was registered with http://www.clinicaltrials.gov (NCT00461747) and Eudra CT (no. 2005-001110-41).

RESUMEN

This is the first prospective study of deferasirox in adult allogeneic hematopoietic stem cell transplant recipients with transfusional iron overload in hematologic malignancies. Patients at least six months post transplant were treated with deferasirox at a starting dose of 10 mg/kg/day for 52 weeks or until serum ferritin was less than 400 ng/mL on two consecutive occasions. Thirty patients were enrolled and 22 completed the study. A significant reduction from baseline in median serum ferritin and in liver iron concentration at 52 weeks was observed in the overall population: from 1440 to 755.5 ng/mL (P=0.002) and from 14.5 to 4.6 mg Fe/g dw (P=0.0007), respectively. Reduction in serum ferritin in patients who did not discontinue deferasirox therapy was significantly greater than that found in those who prematurely discontinued the treatment (from 1541 to 581 ng/mL vs. from 1416 to 1486 ng/mL; P=0.008). Drug-related adverse events, reported in 17 patients (56.7%), were mostly mild to moderate in severity. There were no drug-related serious adverse events. Twelve patients (40.0%) showed an increase of over 33% in serum creatinine compared to baseline and greater than the upper limit of normal on two consecutive visits. Two patients (6.7%) with active graft-versus-host disease showed an increase in alanine aminotransferase exceeding 10 times upper limit of normal; both resolved. In this prospective study, deferasirox provided a significant reduction in serum ferritin and liver iron concentration over one year of treatment in allogeneic hematopoietic stem cell transplant recipients with iron overload. In addition, the majority of adverse events related to deferasirox were mild or moderate in severity. (clinicaltrials.gov identifier:01335035).

RESUMEN

BACKGROUND: Ineffective management of obstetric emergencies contributes significantly to maternal and neonatal morbidity and mortality in Mexico. PRONTO (Programa de Rescate Obstétrico y Neonatal: Tratamiento Óptimo y Oportuno) is a highly-realistic, low-tech simulation-based obstetric and neonatal emergency training program. A pair-matched hospital-based controlled implementation trial was undertaken in three states in Mexico, with pre/post measurement of process indicators at intervention hospitals. This report assesses the impact of PRONTO simulation training on process indicators from the pre/post study design for process indicators. METHODS: Data was collected in twelve intervention facilities on process indicators, including pre/post changes in knowledge and self-efficacy of obstetric emergencies and neonatal resuscitation, achievement of strategic planning goals established during training and changes in teamwork scores. Authors performed a longitudinal fixed-effects linear regression model to estimate changes in knowledge and self-efficacy and logistic regression to assess goal achievement. RESULTS: A total of 450 professionals in interprofessional teams were trained. Significant increases in knowledge and self-efficacy were noted for both physicians and nurses (p <0.001- 0.009) in all domains. Teamwork scores improved and were maintained over a three month period. A mean of 58.8% strategic planning goals per team in each hospital were achieved. There was no association between high goal achievement and knowledge, self-efficacy, proportion of doctors or nurses in training, state, or teamwork score. CONCLUSIONS: These results suggest that PRONTO's highly realistic, locally appropriate simulation and team training in maternal and neonatal emergency care may be a promising avenue for optimizing emergency response and improving quality of facility-based obstetric and neonatal care in resource-limited settings. TRIAL REGISTRATION: NCT01477554.

RESUMEN

BACKGROUND: Migraine is a common and disabling primary headache disorder. Several drugs targeting calcitonin gene-related peptide (CGRP), such as erenumab (an anti-CGRP receptor mAb), have been developed recently. However, the real-world effects of erenumab are not well understood. OBJECTIVE: To assess the clinical effectiveness and safety of erenumab for reducing migraine intensity and frequency in the real world. METHODS: A systematic search of PubMed, Scopus, Web of Science and the Cochrane Library was conducted from inception to December 2023. Studies estimating the real-world effect of erenumab on monthly migraine days (MMD), monthly headache days (MHD), headache impact test (HIT-6), number of days in medication (NDM), acute monthly intake (AMI), pain intensity (PI) and safety outcomes were included. Meta-analyses of proportions or mean differences were performed. RESULTS: Fifty-three studies were included. At 3-months, the effect was -7.18 days for MMD, -6.89 days for MHD, -6.97 for HIT-6, -6.22 days for NDM, -15.75 for AMI, and -1.71 for PI. Generally, the effect at 6- and 12-months increased slightly and gradually. The MMD/MHD response rates revealed that approximately one-third of patients exhibited a response greater than 30%, while one-sixth demonstrated a response exceeding 50%. Additionally, 3-4% of patients achieved a response rate of 100%. Adverse event rates were 0.34 and 0.43 at 6- and 12-months, respectively. CONCLUSION: This study provides strong evidence of the effectiveness and safety of erenumab in the real world; to our knowledge, this is the first real-world meta-analysis specific to erenumab. Erenumab represents a solid therapeutic option for physicians.

RESUMEN

Parasitological studies of long-term inter-annual variations provide more precise and reliable information about the biological structure of fish parasite communities, and constitute a reference data base for future studies. A total of 1103 blue sea catfish Ariopsis guatemalensis from a tropical eutrophic coastal lagoon were examined for parasites over a 22-year period (from May 2000 to October 2022), to test the hypothesis that parasite communities of this host, should exhibit greater variations in their structure and species composition mainly over long-term periods. Three species of monoxenous (single-host life cycle), and nine of heteroxenous (multi-host life cycle) parasites were identified. The results indicated that parasite species composition of this catfish has remained stable over a 22-years period. However, the community structure has registered notable changes over periods of several years, mainly due to the replacement of the numerically dominant species. Temporal variations in the infection dynamics of component parasite species, were possibly caused by a combination of biotic and abiotic factors, influenced by the seasonal dry/rainy cycle, which can affect the availability of intermediate host populations, as well as the feeding and reproductive behavior of the host.

RESUMEN

A total of 366 individuals of Lutjanus argentiventris (Peters, 1869) were collected over a 5-yr period (October 2018 to June 2022) from Acapulco Bay, Mexico. Parasite communities in Lutjanus argentiventris were quantified and analyzed to determine the main factors that generate changes in species richness and/or species composition over time. The digeneans and copepods were the best-represented parasite groups. The parasite communities were characterized by a high numerical dominance of ectoparasites, mainly isopod larvae. Species richness at the component community level (9-23 species) was similar to the reported richness in other Lutjanus spp. The parasite communities of Lutjanus argentiventris exhibited high variability in species composition, suggesting that each parasite species may respond differently to environmental changes. However, the species richness and diversity were fairly stable over time; therefore, a clear pattern of interannual variation was not observed. Variations in the community structure probably were due to factors such as host traits (e.g., feeding behavior and body size), and possible interannual differences in environmental factors amplified by the occurrence of the anomalous event of La Niña.

RESUMEN

In view of the public consultation recently launched by the World Health Organization on Regulatory Convergence of Cell and Gene Therapy Products and the Proposal for a Regulation on substances of human origin (SoHO) repealing the European Union Directives on Blood and on Tissues and Cells, an opportunity arises to define an ethical and transparent framework of collaboration between industry and authorities responsible for SoHO-derived products, comprising medicines, medical devices, transfusion, and transplantation. The commodification of SoHO-derived medicinal products and medical devices entails important risks to the sustainability of healthcare systems and threatens the equitable access of patients to innovative therapies. It may also jeopardize the principle of altruistic donation of SoHO that is required for the treatment and survival of thousands of patients every year. This article puts forward several proposals aimed at reconciling the ethical principles of voluntary and unpaid SoHO donation and the noncommercialization of the human body with obtaining a profit that allows business activities, while ensuring high quality, safety, and efficacy standards of tissues and cells for clinical use.

RESUMEN

Strange oceanographic events such as El Niño and La Niña may have indirect effects on the local transmission processes of intestinal parasites due to the reduction or increase in populations of potential intermediate or definitive hosts. A total of 713 individuals of Lutjanus inermis (Peters) were collected over an 8-year period (October 2015 to July 2022) from Acapulco Bay, Mexico. Parasite communities in L. inermis were quantified and analysed to determine if they experienced interannual variations in species composition and structure as a result of local biotic and abiotic factors influenced by oceanographic events, such as El Niño-Southern Oscillation (ENSO), or La Niña, the cool phase of the ENSO climate pattern. Twenty-six taxa of metazoan parasites were recovered and identified: two Monogenea, eight Digenea, two Acanthocephala, four Nematoda, one Cestoda, seven Copepoda, and two Isopoda. Species richness at the component community level (8 to 17 species) was similar to reported richness in other species of Lutjanus Bloch. Parasite communities of L. inermis exhibited high inter-annual variation in the abundance of component species of parasite. However, the species richness and diversity were fairly stable over time. Climatic episodes of El Niño and La Niña probably generated notable changes in the structure of local food webs, thus indirectly influencing the transmission rates of intestinal parasite species. Changes in species composition and community structure of parasites possibly were due to variations in feeding behaviour during the events and differences in the host body size.

RESUMEN

BACKGROUND: Migraine is a common and disabling primary headache disorder, associated with many medical comorbidities, highly prevalent, with complex treatment and management. Currently, monoclonal antibodies targeting the trigeminal sensory neuropeptide, calcitonin gene-related peptide (CGRP), are available. The aim of this protocol is to provide a review comparing the effects and safety profile of different monoclonal antibodies in migraine patients. METHODS: The literature search will be performed through the MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP), Web of Science and Scopus databases, following the PICO strategy. Real World studies and randomized clinical trials assessing the effect of monoclonal antibodies against CGRP interventions (erenumab, eptinezumab, fremanezumab and galcanezumab) on monthly migraine days (MMD), monthly headache days (MHD), headache impact test (HIT-6) and triptan days of use (TriD) will be included. In Real World studies, the DerSimonian and Laird method will be used to calculate pooled estimates of the mean change difference and in randomized clinical trials, a network meta-analysis will be performed to estimate the comparative effects of different monoclonal antibodies against CGRP. RESULTS: The findings of this study will be reported in a peer-reviewed journal. CONCLUSIONS: This study will provide evidence to health professionals on the efficacy and safety of different monoclonal antibodies against CGRP on the outcomes studied.

RESUMEN

Background: The clinical and epidemiological implications of abnormal immune responses in COVID-19 for latent tuberculosis infection (LTBI) screening are unclear. Methods: We reviewed QuantiFERON TB Gold Plus (QFT-Plus) results (36,709 patients) from July 2016 until October 2021 in Asturias (Spain). We also studied a cohort of ninety hospitalized patients with suspected/confirmed COVID-19 pneumonia and a group of elderly hospitalized patients with COVID-19 who underwent serial QFT-Plus and immune profiling testing. Results: The indeterminate QFT-Plus results rate went from 1.4% (July 2016 to November 2019) to 4.2% during the COVID-19 pandemic. The evolution of the number of cases with low/very low interferon-gamma (IFN-gamma) response in the mitogen tube paralleled the disease activity and number of deaths during the pandemic waves in our region (from March 2020 to October 2021). The percentages of positive QFT-plus patients did not significantly change before and during the pandemic (13.9% vs. 12.2%). Forty-nine patients from the suspected/confirmed COVID-19 pneumonia cohort (54.4%) had low/very low IFN-gamma response to mitogen, 22 of them (24.4%) had severe and critical pneumonia. None received immunosuppressants prior to testing. Abnormal radiological findings (P = 0.01) but not COVID-19 severity was associated with low mitogen response. Immune profiling showed a reduction of CD8 + T cells and a direct correlation between the number of EMRA CD8 + T-cells and IFN-gamma response to mitogen (P = 0.03). Conclusion: Low IFN-gamma responses in mitogen tube of QFT-Plus often occur in COVID-19 pneumonia, which is associated with a low number of an effector CD8 + T-cell subset and does not seem to affect LTBI screening; however, this abnormality seems to parallel the dynamics of COVID-19 at the population level and its mortality.

RESUMEN

Integrating traditional midwives (TMs) as labor support in cline-based care may be an ideal solution to improving maternity services in the Mexico and worldwide. We conducted interviews and focus groups with 65 TMs and 24 interviews with public health system personnel to assess the acceptability and challenges of this proposal. Both TMs and personnel perceive this new role as having professional benefits. Challenges include TMs' and clinic personnel's previous negative experience with one another and unfamiliarity with the doula role. Interactive trainings introducing the doula role and improving professional relations between TMs and personnel are necessary to assure success of this proposal.

RESUMEN

PROBLEM: In Mexico, women are often disrespected and abused during birth, evidence-based practices are seldom used, while outdated and dangerous procedures linger. BACKGROUND: Disrespectful and abusive practices in Mexico have been reported but are not necessarily well-documented; none of the reports so far have relied on direct observation of births. AIM: To describe birth practices and factors associated with respectful and evidence-based care at 15 referral hospitals in Mexico. METHODS: We observed 401 births from 2010-2016. We analysed woman, provider, and hospital characteristics and their association with the performance of 14 evidence-based and 15 respectful birth practices via descriptive statistics and multiple logistic regression models. FINDINGS: Only in four births were all the analysed evidence-based and respectful-birth practices performed. Essential interventions like uterine massage was only given to 46.1% of women and the administration of a uterotonic soon after birth only occurred in 58.3% of births. Professionals who were trained in respectful birth care were more likely to address women by their name (Odds Ratio=3.34, p<0.05), allow consumption of liquids during labour (Odds Ratio=31.6, p<0.05), encourage skin-to-skin contact (Odds Ratio=31.82, p<0.05), and examine the placenta after birth (Odds Ratio=16.55, p<0.01); they were less likely to perform episiotomies (Odds Ratio=0.27, p<0.05). DISCUSSION: This study reveals low rates of evidence-based practices and respectful maternity care but shows training in the topic can have a considerable positive impact. Our results call for further efforts to improve the quality of maternal healthcare, a universal right.

RESUMEN

PROBLEM AND BACKGROUND: During the past two decades, Mexico has launched innovative maternal health initiatives to improve maternal and neonatal outcomes, placing emphasis on the incorporation of professional midwifery practices into the healthcare system. This study explored the perceptions of healthcare providers and women using public birth care services regarding professional midwifery practices and how can the inclusion of evidence-based midwifery techniques improve the quality of service. METHODOLOGY: We conducted a qualitative, cross-sectional study of three healthcare networks in Mexico. A content analysis was performed of data collected through 109 semi-structured interviews: 72 with healthcare providers and 37 with women. RESULTS: Healthcare providers and women had minimal knowledge of the competencies and skills of professional midwives. Medical personnel accepted the incorporation of some evidence-based midwifery practices. Women had experienced fear and anguish during childbirth so they considered that incorporating professional midwifery practices into maternal health services would be favourable in that it would render birth care more respectful. DISCUSSION AND CONCLUSIONS: Healthcare providers are willing to consider the inclusion of some evidence-based midwifery practices in health services and regard assistance from professional midwives. They believe that structural conditions will complicate their incorporation. Although the women interviewed had experienced fear, anxiety and loneliness during childbirth, most of them admitted to feeling "safer" in a hospital (secondary-care health centre) setting where possible complications could be resolved. This perception of safety served to justify the delivery of healthcare in a manner that is inattentive to women's needs, which go beyond biomedical issues and include emotions and the positive experience of childbirth.
