Conclusão: é necessário que os profissionais reflitam sobre suas ações, condicionando-as à humanização no parto, em observância aos princípios bioéticos.

Objective: to evaluate the clinical factors associated with women's well-being during labor and delivery in the light of bioethics principlism and deontology. Method: a cross-sectional study with a quantitative approach was conducted. It involved 396 postpartum women admitted to a municipal hospital in the southwest of Bahia. Data were collected from January to May 2023, after approval from the research ethics committee. The data were tabulated using Excel software and analyzed using SPSS v.25 through Multinomial Logistic Regression. Results: majority of the sample exhibited well-being with health care assistance. Women who underwent delivery performed by non-medical professionals showed higher chances of "adequate" levels of well-being. Additionally, women who did not undergo cesarean delivery showed increased chances of well-being. Conclusion: It is necessary for professionals to reflect on their actions, conditioning them to the humanization of childbirth, according to bioethical principles.

RESUMEN

The medical profession faces multiple challenges worldwide in the 21st century. This integrative review of the literature published between 2014 to 2018 on supply and demand in the health care labor market was based on a search of the SciELO, Biblioteca Virtual em Saúde (Virtual Health Library), and MEDLINE databases, in addition to specific periodicals in the area of Health Economics. The final sample included 21 studies, 13 of which were related to workforce supply and 8 to demand. Physicians reported that work satisfaction was an important factor in accepting a job offer, including being close to their family, working with colleagues in the same specialty, and the possibility of career advancement. For health system users, a fundamental question is how to resolve the unequal distribution of physicians.

A profissão médica se defronta globalmente com múltiplos desafios no século XXI, entre os quais podem-se destacar o crescimento populacional e a inovação tecnológica e a sua implementação na medicina. Este artigo buscou identificar na literatura científica aspectos relevantes acerca do mundo do trabalho para a profissão médica. Trata-se de uma revisão integrativa, que considerou as publicações do quinquênio de 2014 a 2018. A seleção dos artigos para o presente estudo foi realizada nas bases de dados Scientific Electronic Library Online, Biblioteca Virtual em Saúde, Medical Literature Analysis and Retrieval System Online, além de periódicos específicos da área de economia e saúde. Como resultado desta revisão, foram selecionados 21 artigos, sendo identificados 13 com temáticas referentes à oferta da força de trabalho médico e 8 com temáticas referentes à demanda da força de trabalho, de acordo com a classificação que emergiu pelos critérios adotados.

Já com relação à demanda da força de trabalho, ou seja, para quem busca os serviços de tais profissionais, uma questão fundamental é como resolver problemas de escassez de profissionais médicos que estão relacionados a uma distribuição desigual em determinados locais.

RESUMEN

Introduction: The effects of the COVID-19 pandemic on Latin American labor markets continue to be quantified, to identify the social and economic impacts that this pandemic had, and to design more efficient public policies that would protect the most vulnerable groups. For this reason, the research question was as follows: what were the changes in the labor formality rates before and two years after the main contingency measures of the COVID-19 pandemic were implemented? Methods: Using data from Argentina, Bolivia, Chile, Colombia, Ecuador, Guatemala, Mexico, Peru, and Uruguay, the formality rate (τ) was analyzed, which was calculated using a weighted average between the formal employment rates of the number (i) of economic sectors (p) in a specific period (t). Results: The results suggest that the weighted labor formality rate increased in the countries of the region. These changes in formality could be the result of greater capital accumulation, the integration of productive processes, the integration of commercialization processes, and differentiated fiscal stimuli (i.e., the intrasectoral aspect), but it was not due to the displacement of workers from highly informal economic sectors to more formalized sectors (i.e., the intersectoral component). Discussion: The findings emphasized the precarious situation of women in the region, regardless of the country, particularly in Ecuador, Peru, Bolivia, and Argentina. These findings suggest the need to design public policies that reverse the current situation of the labor market and prevent future economic shocks, with special emphasis on the informal sector and women.

RESUMEN

ABSTRACT Introduction. Preterm birth is a major medical, social, and economic problem that causes a large proportion of neonatal mortality and morbidity, has a high impact on the healthcare system, and affects family quality of life. The weight of newborns with mothers with periodontal disease is significantly lower compared to mothers not affected by this oral disease. This adverse outcome is considered a global public health problem based on epidemiological data. Objective. To determine the association between the prevalence of preterm births and periodontal disease in Bolivia, Chile, and Colombia from 2000 to 2020. Materials and methods. This ecological study considered the population of women in Bolivia, Chile, and Colombia, according to the prevalence of preterm births and periodontal disease discriminated by age. The study covered the period between 2000 and 2020. The search strategy within the Institute for Health Metrics and Evaluation investigative tool included prevalence, age groups, causes of preterm births and periodontal disease, context and locations, women, and rates. Statistical analysis included a simple linear regression between preterm births and periodontal disease for each age group within each country. Results. Preterm birth rates were higher in the 15-19 years age group (Bolivia: 697,563; Chile: 844,864; Colombia: 804,126). The periodontal disease prevalence increased with age, as we observed in the 45-49 years group (Bolivia: 22,077,854; Chile: 34,297,901, Colombia: 32,032.830). According to age groups, the linear regression was statistically significant (p < 0.001) in all age groups for the Bolivian population over 30 years for the Colombian, and only in the 15-19 years group for the Chilean women. Conclusion. An association was found between preterm births and periodontal disease in all age groups in Bolivia, only in the group of 15 to 19 years in Chile, and 30 years and up in Colombia over the 20-year period.

RESUMEN

Abstract Introduction. Postpartum anxiety after childbirth is a common condition among pregnant women due to reasons such as the uncertainty of experiencing pregnancy and childbirth for the first time, or previous negative experiences. Fear of childbirth can affect the mother's baby care process. Objective. This study was conducted analytically with a single-subject design to determine the effects of maternal concerns about childbirth and the postpartum period on obsessive and compulsive behaviors related to baby care. Materials and methods. The study was conducted with 260 mothers. Data were collected using a descriptive information form, and the scales 'Fear of Childbirth and Postpartum Period', and 'Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care'. The data were analyzed using the SPSS™ software to calculate percentages, mean values, t tests, ANOVA, Pearson's correlation, and simple linear regression analysis. Results. A statistically significant and positive correlation was found between participant scores of the 'Fear of Childbirth and Postpartum Period' and the 'Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care' scales (p < 0.01). The regression model showed that 18.0% of the total variance in the obsessive and compulsive behaviors of mothers in the postpartum was explained by the fear of childbirth and the postpartum period (corrected R2 = 0.180). Conclusions. Fear of childbirth and the postpartum period were moderate. However, as the fear of women regarding childbirth and the postpartum period increased, their postpartum obsessive and compulsive behaviors about baby care also increased.

Resumen Introducción. La ansiedad del parto y el posparto es una condición común entre las mujeres embarazadas por la incertidumbre de vivir el embarazo y el parto por primera vez o por previas experiencias negativas. El miedo al parto puede afectar el proceso del cuidado del bebé de la madre. Objetivo. Determinar el efecto de las preocupaciones maternas sobre el parto y el puerperio y su efecto sobre las conductas obsesivas y compulsivas relacionadas con el cuidado del bebé. Materiales y métodos. El estudio se realizó con 260 madres. Los datos fueron recolectados en el formulario de información descriptiva y se usaron la "Escala de miedo al parto y al período posparto" y la de "Comportamientos obsesivos y compulsivos de las madres en el período posparto relacionados con el cuidado del bebé". Los datos fueron evaluados mediante el software SPSS™ mediante el cálculo de porcentajes, promedio, prueba t, ANOVA, correlación de Pearson y análisis de regresión múltiple. Resultados. Se encontró una correlación positiva y estadísticamente significativa entre la "Escala de miedo al parto y del período posparto" y la de "Comportamientos obsesivos y compulsivos de las madres en el período posparto relacionadas con el cuidado del bebé" (p < 0.01). En el modelo creado por análisis de regresión se observó que el 18,0% del cambio en la escala de comportamientos obsesivos-compulsivos estaba explicado por el miedo al parto y al puerperio (R2corregido = 0,180). Conclusiones. En el estudio se determinó que el miedo al parto y al puerperio era moderado. Sin embargo, a medida que aumentaba el puntaje de miedo al parto y al período posparto, también aumentaban los comportamientos obsesivos y compulsivos de las madres en el puerperio relacionados con el cuidado del bebé.

RESUMEN

INTRODUCTION: The type of perineal repair can have significant long-term effects on various functions in a woman's postpartum life. The aim was to compare urinary incontinence (UI), women's satisfaction, pelvic floor muscle strength (PFMS), and sexual function according to the type of perineal repair (surgical glue or suture thread) during the first eight months after normal childbirth. METHODS: A controlled randomized clinical trial of 133 primiparous women undergoing perineal repair during birth with surgical glue or sutures, evaluated during labor and monitored up to 8 months postpartum, from March 2017 to September 2018, in the city in São Paulo, Bazil. Descriptive and inferential analyses were carried out. RESULTS: A total of 133 women were included in the study, 111 (83.5%) were assessed between 10 to 20 days postpartum, 121 (91.0%) between 50 to 70 days, and 54 (40.6%) between 6 to 8 months. There were no significant differences for UI concerning the type of repair; however, there was a significant difference concerning the postpartum period (p=0.031), with a higher prevalence at two months. Most women reported satisfaction, with the highest levels reported two months after birth (p=0.019). For PFMS, the mean of the glue and suture groups were 32.4 cmH2O and 27.4 cmH2O, but not significant. Women in the glue group showed higher mean values in all sexual function domains but without significance. CONCLUSIONS: Surgical glue showed good aesthetic and functional results in the perineum at eight months postpartum.

RESUMEN

Los trastornos músculo-esqueléticos relacionados con el trabajo constituyen motivo de preocupación para la comunidad científica, avalado por su efecto negativo en la vida de los trabajadores y la productividad de las empresas. En el proceso de fundición de metales, los moldeadores manuales con pisón neumático exteriorizan manifestaciones de estas afecciones. Ello indujo a realizar una investigación que tuvo como objetivo elaborar un programa de Gimnasia Laboral para contribuir a la atención de los trastornos músculo-esqueléticos en los moldeadores manuales metalúrgicos. Para recopilar, analizar y procesar los datos se emplearon métodos teóricos, empíricos y matemático-estadísticos, entre ellos el histórico-lógico, analítico-sintético, inductivo-deductivo, sistémico-estructural-funcional, la observación participante, encuesta, entrevista, revisión documental, el experimento, criterio de usuarios y la estadística descriptiva e inferencial. La población objeto de estudio estuvo conformada por 19 moldeadores manuales metalúrgicos, seleccionados de forma intencional. El diagnóstico y la sistematización teórica alcanzada posibilitaron elaborar un programa de Gimnasia Laboral, en correspondencia con los requerimientos del proceso de moldeo, cuya efectividad fue constatada.

As lesões músculo-esqueléticas relacionadas com o trabalho são motivo de preocupação para a comunidade científica, sustentadas pelos seus efeitos negativos na vida dos trabalhadores e na produtividade das empresas. No processo de fundição do metal, os moldadores manuais com compactador pneumático externalizam as manifestações dessas condições. Isso originou uma pesquisa que teve como objetivo desenvolver um programa de Ginástica Laboral para contribuir no cuidado de lesões osteomusculares em moldadores manuais metalúrgicos. Para coletar, analisar e tratar os dados foram utilizados métodos teóricos, empíricos e matemático-estatísticos, incluindo histórico-lógico, analítico-sintético, indutivo-dedutivo, sistêmico-estrutural-funcional, observação participante, levantamento, entrevista, revisão documental, o experimento, critérios de usuário e estatísticas descritivas e inferenciais. A população em estudo foi composta por 19 modeladores manuais metalúrgicos, selecionados intencionalmente. O diagnóstico e a sistematização teórica conseguidos permitiram desenvolver um programa de Ginástica Laboral, em correspondência com as exigências do processo de moldagem, cuja eficácia foi verificada.

Work-related musculoskeletal disorders are a cause of concern for the scientific community, supported by their negative effect on the lives of workers and the productivity of companies. In the metal casting process, manual molders with pneumatic tamper externalize manifestations of these conditions. This led to carrying out a research that aimed to develop a Labor Gymnastics program to contribute to the care of musculoskeletal disorders in metallurgical manual shapers. To collect, analyze and process the data, theoretical, empirical and mathematical-statistical methods were used, including historical-logical, analytical-synthetic, inductive-deductive, systemic-structural-functional, participant observation, survey, interview, documentary review, the experiment, user criteria and descriptive and inferential statistics. The population under study was made up of 19 metallurgical manual shapers, intentionally selected. The diagnosis and theoretical systematization achieved made it possible to develop a Labor Gymnastics program, in correspondence with the requirements of the molding process, whose effectiveness was verified.

RESUMEN

The Rio de Janeiro Marine Aquarium (AquaRio) is the first to successfully maintain and reproduce the spiny butterfly ray (Gymnura altavela), providing unique information about the species' biology. Seven rays were kept in captivity between 2018 and 2023, two captured on the southeastern coast of Brazil and five born in the aquarium. The applied abiotic conditions and nutrition allowed for the survival, growth, and reproduction of these individuals. Growth parameters (asymptotic disk width-DW∞ and growth coefficient-k) were estimated based on the von Bertalanffy model using the Fabens method for males and females separately. The best models estimated DW∞ = 106.47 cm and k = 0.396 for males and DW∞ = 172.2 cm and k = 0.190 for females. Sexual dimorphism was corroborated, with females reaching larger sizes and presenting slower growth rates than males. The estimated k values were higher than those estimated for rays of similar size to G. altavela in the natural environment, probably due to the constant water temperature (around 25.5°C), food abundance, low population density, reduced predation rates, and high water quality in the captive environment. A comparison of the captivity findings with other studies on G. altavela age and growth in the Atlantic and Mediterranean indicates a broad phenotypic plasticity regarding growth. Three G. altavela reproductions were recorded, with size at birth appearing to be a key factor for pup's survival. Behavioral pattern observations associated with reproduction are also described, encompassing chasing and copulation, whereas the species' internal morphology is described through coelomic cavity ultrasound scanning.

RESUMEN

Background/Objectives: Although oxytocin administration is recommended for delayed labor progress, there is no consensus over the preferred optimal dose of oxytocin. We aimed to perform a meta-analysis of pregnancy outcomes comparing high-dose versus low-dose oxytocin regimens for augmentation of delayed labor. Methods: PubMed, Embase, and Cochrane databases were systematically searched for studies comparing high-dose with low-dose oxytocin for labor augmentation from inception up to May 2023. The outcomes assessed were cesarean rate, instrumental delivery rate, postpartum hemorrhage, neonatal death, and uterine tachysystole. Subgroup analysis was performed with randomized controlled trials (RCTs) and propensity-matched studies. Statistical analysis was performed using Rstudio. Heterogeneity was assessed with I2 statistics, and a random-risk effect was used if I2 > 50%. Results: Twenty-one studies met inclusion criteria, and eighteen were RCTs. A total of 14.834 patients were included, of whom 7.921 (53.3%) received high-dose and 6.913 (46.6%) received low-dose oxytocin during labor augmentation. No statistical differences were found in cesarean delivery, neonatal mortality, postpartum hemorrhage and vaginal instrumentation rate. However, uterine tachysystole incidence was significantly higher with high-dose oxytocin (95% Cl, 1.30-1.94, p = 0.3; 0.6; I2 = 9%). Conclusions: Labor augmentation with a low-dose oxytocin regimen is effective as with a high-dose regimen, but with significantly less uterine tachysystole events, which can lead to intrauterine and neonatal complications. Our findings suggest that a low-dose regimen may be safe and effective for labor augmentation in medical practice.

RESUMEN

OBJECTIVE: To look into the effects of different anesthesia methods on the labor process and the expression of serum estrogen and progesterone in primiparas with painless labor. METHODS: 60 primiparas receiving painless labor were selected as the research objects, and they were divided into either a Spinal & Continuous epidural anesthesia group (n = 30) or a continuous epidural anesthesia group (n = 30), anesthesia is administered using the corresponding anesthesia method. The authors compared serum estrogen and progesterone, inflammatory index expression, pain degree and neonatal health status in different periods. RESULTS: At T2 and T3, serum P, LH, FSH and E2 levels in the Spinal & Continuous epidural anesthesia group were signally lower than those in the Spinal & Continuous epidural anesthesia group (p < 0.05). Spinal & Continuous epidural anesthesia group harbored faster onset and longer duration of sensory block and motor block than the Continuous epidural anesthesia group (p < 0.05). SAS and SDS scores of the Spinal & Continuous epidural anesthesia group were clearly lower than those of the Continuous epidural anesthesia group (p < 0.05). VAS score and serum TNF-α, IL-6 levels of pregnant women in the Spinal & Continuous epidural anesthesia group were memorably lower than those in the Continuous epidural anesthesia group at T2 and T3 (p < 0.05). The total incidence of postoperative complications in the Spinal & Continuous epidural anesthesia group was distinctively lower than that in the Continuous epidural anesthesia group (p < 0.05). CONCLUSION: Spinal anesthesia combined with continuous epidural anesthesia has a better anesthesia effect in the painless labor of primiparas, which can effectually ameliorate the labor process and the expression of serum estrogen and progesterone.

In this study, the researchers aimed to determine the validity and reliability of cervicometry and the Bishop score for diagnosing threatened preterm labor in the high-risk obstetric service at the Hospital de la Mujer in La Paz during the period from January to March 2019. The study included pregnant women, and the results showed varying sensitivities and specificities for cervicometry and the Bishop score. The concordance between these two methods was found to be minimal. OBJECTIVE: to determine the validity and reliability of cervicometry and the Bishop score to diagnose threatened preterm labor. MATERIAL AND METHODS: retrospective, quantitative, and analytical study to validate a diagnostic test. SAMPLE: the study included 185 pregnant women with a single fetus, at gestational ages between 22 and 37 weeks, who underwent cervicometry assessment during the period from January to March 2019. RESULTS: the frequency of preterm labor in pregnant women diagnosed with threatened preterm labor was 27%, with higher prevalence in women with 4 or more previous deliveries. Cervicometry evaluation to diagnose threatened preterm labor showed a sensitivity of 66.0%, specificity of 94.8%, positive predictive value (+) of 82.5%, and negative predictive value (-) of 88.3%. Bishop score evaluation had a sensitivity of 4.0%, a specificity of 99.3%, a positive predictive value (+) of 66.7%, and a negative predictive value (-) of 73.6%. The concordance index between cervicometry and the Bishop score was minimal (0.017). The area under the ROC curve for cervicometry in relation to the final diagnosis of preterm labor was 0.905, with an optimal cutoff point of 30.5 mm, corresponding to a sensitivity of 90.4% and specificity of 78.0%. CONCLUSION: the concordance between cervicometry and the Bishop score to diagnose threatened preterm labor is minimal

RESUMEN

Introduction: Fetal heart rate variability (fHRV) is a tool used to investigate the functioning of the fetal autonomic nervous system. Despite the significance of preeclampsia, fHRV during the latent phase of labor has not been extensively studied. This study aimed to evaluate fetal cardiac autonomic activity by using linear and nonlinear indices of fHRV analysis in women diagnosed with preeclampsia without hypertensive treatment during gestation, compared to normotensive women during the latent phase of labor. Methods: A cross-sectional and exploratory study was conducted among pregnant women in the latent phase of labor, forming three study groups: normotensive or control (C, 38.8 ± 1.3 weeks of pregnancy, n = 22), preeclampsia with moderate features (P, 37.6 ± 1.4 weeks of pregnancy n = 10), and preeclampsia with severe features (SP, 36.9 ± 1.2 weeks of pregnancy, n = 12). None of the participants received anti-hypertensive treatment during their pregnancy. Linear and nonlinear features of beat-to-beat fHRV, including temporal, frequency, symbolic dynamics, and entropy measures, were analyzed to compare normotensive and preeclamptic groups. Results: Significantly lower values of multiscale entropy (MSE) and short-term complexity index (Ci) were observed in the preeclamptic groups compared to the C group (p < 0.05). Additionally, higher values of SDNN (standard deviation of R-R intervals) and higher values of low-frequency power (LF) were found in the P group compared to the C group. Conclusion: Our findings indicate that changes in the complexity of fetal heart rate fluctuations may indicate possible disruptions in the autonomic nervous system of fetuses in groups affected by undiagnosed preeclampsia during pregnancy. Reduced complexity and shifts in fetal autonomic cardiac activity could be associated with preeclampsia's pathophysiological mechanisms during the latent phase of labor.

RESUMEN

Social insects live in communities where cooperative actions heavily rely on the individual cognitive abilities of their members. In the honey bee (Apis mellifera), the specialization in nectar or pollen collection is associated with variations in gustatory sensitivity, affecting both associative and non-associative learning. Gustatory sensitivity fluctuates as a function of changes in motivation for the specific floral resource throughout the foraging cycle, yet differences in learning between nectar and pollen foragers at the onset of food collection remain unexplored. Here, we examined nectar and pollen foragers captured upon arrival at food sources. We subjected them to an olfactory proboscis extension reflex (PER) conditioning using a 10% sucrose solution paired (S10%+P) or unpaired (S10%) with pollen as a co-reinforcement. For non-associative learning, we habituated foragers with S10%+P or S10%, followed by dishabituation tests with either a 50% sucrose solution paired (S50%+P) or unpaired (S50%) with pollen. Our results indicate that pollen foragers show lower performance than nectar foragers when conditioned with S10%. Interestingly, performance improves to levels similar to those of nectar foragers when pollen is included as a rewarding stimulus (S10%+P). In non-associative learning, pollen foragers tested with S10%+P displayed a lower degree of habituation than nectar foragers and a higher degree of dishabituation when pollen was used as the dishabituating stimulus (S10%+P). Altogether, our results support the idea that pollen and nectar honey bee foragers differ in their responsiveness to rewards, leading to inter-individual differences in learning that contribute to foraging specialization.

RESUMEN

Objective: To evaluate whether the continuous support provided by doulas influences the endogenous release of serotonin in parturients. Methods: This pilot study included 24 primigravidae at term. Of these, 12 women received continuous doula support (Experimental Group), whereas the other 12 received the usual assistance without doula support (Control Group). Blood samples were collected from all the women at the active and expulsion stages of labor and at the fourth period of labor (Greenberg period) for evaluation of their serotonin levels using high-performance liquid chromatography. Results: The average serotonin concentrations in the control and experimental groups were respectively 159.33 and 150.02 ng/mL at the active stage, 179.13 and 162.65 ng/mL at the expulsion stage, and 198.94 and 221.21 ng/mL at the Greenberg period. There were no statistically significant differences in serotonin concentrations between the two groups at the active and expulsion stages of labor. By contrast, within the experimental group, a significant increase in serotonin concentration was observed in the Greenberg period compared with the levels in the active and expulsion stages (p < 0.05). Conclusion: The novelty of this study relies on the ability to correlate the influence of the continuous support offered by doulas with the release of serotonin in parturients, with the results suggesting that the assistance received during labor can modulate the levels of hormone release in the Greenberg period.

RESUMEN

OBJECTIVE: The safety of assisted reproductive technology can be assessed by examining birth weight as an outcome measure. The objective of this study was to evaluate the effect of endometrial thickness during embryo transfer on newborn birth weight and preterm labor. METHODS: We conducted a retrospective cohort study at the infertility department of a teaching hospital affiliated with a university of medical sciences. Eligible women were ≥18 years old and conceived a singleton pregnancy with embryo transfer and an endometrial thickness of ≥7 mm. None of the patients had diabetes, blood hypertension, and polycystic ovarian syndrome. We assessed maternal and newborn characteristics and perinatal pregnancy outcomes. RESULTS: In total, 100 eligible patients with a mean (SD) age of 32.8 (6.2) years were included. The mean endometrial thickness during embryo transfer was 9.1 (1.2) mm, and the mean birth weight was 3040.7 (565.3)g. There were no statistically significant associations between endometrial thickness and preterm labor (p=0.215) and between endometrial thickness and stillbirth or intra-uterine fetal death (p=0.880). However, after adjusting for confounding factors, the association of endometrial thickness with birth weight was statistically significant [b=124.6 (51.6), p=0.018]. CONCLUSIONS: Within the range of ≥7mm, endometrial thickness during embryo transfer is a predictor of newborn weight; however, it is not related to the risk of preterm labor, stillbirth, or intra-uterine fetal death.

RESUMEN

BACKGROUND: Preterm birth accounts for 60% to 80% of neonatal mortality. Approximately one-third of preterm births are caused by the spontaneous onset of preterm labor. Nevertheless, 70% to 90% of women diagnosed with preterm labor will not deliver within 7 days. Thus, many women will be unnecessarily treated by preterm labor with risk medications. Better tools are needed to categorize women in preterm labor into high or low risk of preterm delivery. OBJECTIVE: This study aimed to evaluate the amino-terminal pro-brain natriuretic peptide concentration in the amniotic fluid as a prognostic test to predict the risk of delivery within 48 hours or 7 days and before 34 0/7 or 37 0/7 weeks of gestation in women in preterm labor. STUDY DESIGN: A total of 102 pregnant women presenting signs and symptoms of spontaneous preterm birth (22 0/7 to 34 0/7 weeks of gestation) were included. Amniotic fluid was obtained by amniocentesis, and amino-terminal pro-brain natriuretic peptide concentration was measured. Below normal concentration was defined as <0.5 multiples of the median of the standard curve according to gestational age. The risk of preterm delivery was estimated according to normal or lower-than-normal amino-terminal pro-brain natriuretic peptide concentrations. The predictive capacity of the test (below normal amino-terminal pro-brain natriuretic peptide concentration) was evaluated to identify spontaneous preterm birth at 48 hours or 7 days from amniocentesis and less than 34 0/7 or 37 0/7 weeks at delivery. RESULTS: For the outcome delivery within 48 hours, lower-than-normal amino-terminal pro-brain natriuretic peptide concentration had 94.6% sensitivity, 73.8% specificity, 96.0% negative predictive value, 3.61 positive likelihood ratio, and 0.07 negative likelihood ratio. For the outcome delivery within 7 days, the test had 93.9% sensitivity, 88.7% specificity, 94.0% negative predictive value, 8.31 positive likelihood ratio, and 0.07 negative likelihood ratio. For the outcomes of spontaneous preterm birth before 34 0/7 and 37 0/7 weeks of gestation, below normal amino-terminal pro-brain natriuretic peptide concentrations had 80.0% sensitivity, 83.0% specificity, 78.0% negative predictive value, 4.70 positive likelihood ratio, and 0.24 negative likelihood ratio and 64.1% sensitivity, 91.7% specificity, 44.0% negative predictive value, 7.70 positive likelihood ratio, and 0.39 negative likelihood ratio, respectively. CONCLUSION: Among patients in spontaneous preterm labor, the detection of lower-than-normal amino-terminal pro-brain natriuretic peptide concentrations (<0.5 multiples of the median) in amniotic fluid has an excellent predictive capacity to identify those patients at low risk of preterm delivery within 48 hours or 7 days.

Introduction: In Paraguay the school of Instrumentation and Surgical Area was created in 1996 linked to the National University, and in 2008 onwards other offers were created in the private sector. The Surgical Instrument Technician can work as instrumentalist, circulating nurse, general coordinator of operating rooms, and coordinator of the central sterilization unit. Objective: to know the work environment of the professional and licensed Surgical Instrument Technician in Paraguay. Methodology: descriptive, quantitative and cross-sectional study. The sample is 167 graduates, graduates of public and private institutions. Non-probability sampling for convenience, the data collection instrument is an electronic questionnaire. Results: 74% are women, 50% have an age range between 21 and 30 years old, 79.6% graduated from a public institution, 40% say they have moderate difficulty finding their first job in the field. Access to employment, 71% was through personal contacts, 72% is dedicated to work as Instrument Technicians, 60% have a job seniority of 1 to 5 years. Among the postgraduates, 30% are university didactics certified. Discussion: Surgical Instrument Technicians meet the requirements to perform other functions in addition to instrumentation and circulating nurses in the operating room. Similarly, other studies show less participation in the administrative area, teaching, marketing and sales. 20 years have elapsed since the first Technicians graduated, being a new profession, not given the importance it deserves. It is noteworthy that the state can save economic resources by hiring Surgical Instrument Technicians, since they are experts in aseptic care and competent in minimizing the amount of time the patient spends in surgery.
