Relationship Between Maternal Age and Macronutrient Content of Colostrum.

BACKGROUND: Little is known about the relationship between maternal age and the macronutrient content of colostrum. RESEARCH AIMS: This study aimed to evaluate the relationship between maternal age and human milk macronutrient content by comparing the concentrations of lactose, proteins, and lipids in the colostrum of women with younger, moderate, and advanced maternal age. METHODS: An observational, cross-sectional study was designed to compare the macronutrient concentrations in the colostrum of women aged < 20 years, 20 to 34 years, and > 34 years (younger, moderate, and advanced maternal age, respectively; n = 33 per group). For each participant, 3 ml of colostrum was collected by manual extraction from the right breast at 10 am, 39-48 hr after delivery, and analyzed using a Miris Human Milk Analyzer. Macronutrient concentrations were compared between the groups using analysis of variance. P < 0.05 was considered significant. RESULTS: Mothers with moderate maternal age had a higher colostrum lipid concentration than those with younger or advanced maternal age (2.3 mg, SD = 1.4 mg vs. 1.5 mg, SD = 1.0 mg vs. 1.6 mg, SD = 0.9 mg, respectively; p = 0.007). Lactose and protein contents in the analyzed samples did not differ among the three study groups. CONCLUSION: This study lends support to the potential variation of lipids in colostrum by maternal age and suggests individual adaptation to the nutritional components of milk to the needs of the infant may be beneficial.

Clinical and serological findings in pregnant women and newborns: patterns of coronavirus disease 2019 placental histopathology.

OBJECTIVE: The objective of this study was to evaluate the correlation between clinical and serological findings of pregnant women and newborns with patterns of histopathologic changes of the placenta diagnosed with coronavirus disease 2019. METHODS: A prospective descriptive study was conducted with pregnant women who were positive for SARS-CoV-2 by reverse transcription polymerase chain reaction or serology (IgG and IgM). Clinical analyses were performed using ELISA to detect anti-SARS-CoV-2 IgG and IgA antibodies using the S1 spike protein domain with the Euroimmun kit. Histopathologic analyses of placentas were performed by two expert pathologists. RESULTS: Maternal SARS-CoV-2 infection was associated with increased neonatal hospital length of stay (p=0.03), increased preterm birth (p=0.04), and Apgar score<7 at 1st min (p=0.00) and 5th min (p=0.02). Pregnant women with positive IgG and/or IgA at delivery had a higher incidence of placental histopathologic changes in addition to a greater likelihood of having an IgG-positive fetus (p<0.0001). Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion changes (p=0.00). CONCLUSION: Maternal SARS-CoV-2 infection was associated with adverse perinatal outcomes. Pregnant women with positive IgG at delivery had a higher incidence of placental histopathologic changes. Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion.

Evaluation and monitoring of eye findings in children exposed to Zika virus during gestation: 3 years of follow-up.

INTRODUCTION: Congenital Zika syndrome (CZS) is a recently described disease. Our main objective was to evaluate and monitor, over 3 years, the ophthalmoscopic findings in children exposed to zika virus (ZIKV) during gestation. METHODS: This prospective observational study was conducted in Rio de Janeiro, Brazil, between April 2016 and May 2019. We evaluated two groups with exanthema serving as a proxy for viremia: (i) children whose mothers had exanthema during pregnancy and (ii) children who had microcephaly without maternal exanthema during pregnancy. We performed indirect ophthalmoscopy at recruitment and every 6 months thereafter. We also tested the association between ocular findings with maternal exanthema, microcephaly, CZS and maternal infection confirmed by reverse transcriptase quantitative polymerase chain reaction and gender. RESULTS: Of the 72 children included, 16 (22.2%) had optic nerve and/or retinal lesions. All 16 had CZS and 15 (93.7%) had microcephaly (14 at birth and 1 postnatally). The child with postnatally acquired microcephaly was born to a mother without exanthema during pregnancy. Fifty-six (77.8%) of the 72 children were followed for a median time of 24 months and none exhibited differences between admission and follow-up examinations. After logistic regression, only microcephaly at birth was associated with eye abnormalities (odds ratio, 77.015; 95% confidence interval, 8.85-670.38; p < 0.001). CONCLUSION: We observed that there was no progression of the lesions over the follow-up period. We also showed that the eye findings were associated only with microcephaly at birth. Attention should be paid to all children born during a ZIKV epidemic, regardless of maternal exanthema and/or microcephaly at birth.

Incidence of bradycardia during noradrenaline or phenylephrine bolus treatment of postspinal hypotension in cesarean delivery: A randomized double-blinded controlled trial.

The treatment of choice for spinal anesthesia-induced hypotension during cesarean section is phenylephrine. As this vasopressor can cause reflex bradycardia, noradrenaline is a suggested alternative. This randomized double-blinded controlled trial included 76 parturients undergoing elective cesarean delivery under spinal anesthesia. Women received noradrenaline in bolus doses of 5 mcg or phenylephrine in bolus doses of 100 mcg. These drugs were used intermittently and therapeutically to maintain systolic blood pressure ≥ 90% of its baseline value. The primary study outcome was bradycardia incidence (<60 bpm) with intermittent bolus administration of these drugs. Secondary outcomes included extreme bradycardia (<40 bpm), number of bradycardia episodes, hypertension (systolic blood pressure > 120% of baseline value), and hypotension (systolic blood pressure < 90% of baseline value and requiring vasopressor use). Neonatal outcomes per the Apgar scale and umbilical cord blood gas analysis were also compared. The incidence of bradycardia in both groups (51.4% and 70.3%, respectively; p = 0.16) were not significantly different. No neonates had umbilical vein or artery pH values below 7.20. The noradrenaline group required more boluses than phenylephrine group (8 vs. 5; p = 0.01). There was no significant intergroup difference in any of the other secondary outcomes. When administered in intermittent bolus doses for the treatment of postspinal hypotension in elective cesarean delivery, noradrenaline, and phenylephrine have a similar incidence of bradycardia. When treating hypotension related to spinal anesthesia in obstetric cases, strong vasopressors are commonly administered, thought these can also have side effects. This trial assessed bradycardia after bolus administration of noradrenaline or phenylephrine, and found no difference in risk for clinically meaningful bradycardia.

Prática dos profissionais da saúde em aleitamento materno e fatores associados: estudo transversal / Health professionals' breastfeeding practices and associated factors: a cross-sectional study

OBJETIVO: Analisar a prática dos profissionais da saúde da atenção básica quanto ao aleitamento materno e fatores associados. MÉTODO: Estudo transversal, analítico, realizado com todos os profissionais da saúde atuantes em aleitamento materno de cinco unidades da atenção básica através de questionário autoaplicável. Para análise da associação das variáveis categóricas com a prática profissional, utilizou-se teste Qui-quadrado com nível de significância de 5%. RESULTADOS: Participaram 38 profissionais. Houve associação estatística significativa (p=0.04597) entre a variável atualização em aleitamento materno nos últimos cinco anos e a prática de implementação em grupos de apoio. O manejo clínico, a orientação quanto aos direitos maternos e o apoio para a resolução de dificuldades na amamentação foram menos informados. CONCLUSÃO: A prática dos profissionais da saúde apresentou fragilidades evidenciando a necessidade de valorização do tema por profissionais e gestores através de estratégias que incluam capacitação contínua e monitoramento do aleitamento materno na rede de atenção básica.

OBJECTIVE: To analyze primary care health professionals' breastfeeding practices and associated factors. METHOD: A cross-sectional and analytical study was carried out with all health professionals working in breastfeeding support in five primary healthcare units, through a self-administered questionnaire. The chi-square test was used with a significance level of 5% to analyze the association of categorical variables with professional practice. RESULTS: Thirty-eight professionals participated. There was a statistically significant association (p=0.04597) between the variable update on breastfeeding in the last five years and the practice of implementing breastfeeding through support groups. Clinical management, guidance on maternal rights, and support for resolving difficulties in breastfeeding were less reported. CONCLUSION: The practice of health professionals showed weaknesses, highlighting the need for professionals and managers to value the breastfeeding issue through strategies that include continuous training and monitoring of breastfeeding in the primary healthcare network.

The Hip of Children with Congenital Zika Syndrome: A Prospective Observational Study.

OBJECTIVE: To assess the clinical and radiographic characteristics of hip joint deformities in children with congenital Zika syndrome (CZS), and the evolution of hip joint deformities in affected infants for the first 3 years of life. STUDY DESIGN: This prospective observational study evaluated orthopedic clinical examinations performed every 3 months to assess hip flexion and extension, lateral and medial rotation, and abduction and adduction, as well as lower limb muscle length and tone. The biannual radiograph comprised anteroposterior panoramic pelvic radiographs with the lower limbs in extension. Percentage of migration was used as a radiographic study tool to measure and evaluate linear hip displacement. RESULTS: From November 2018 to March 2020, we followed 30 children with CZS, of whom 15 (50%) had normal pelvic radiographs on admission; 5 (33.3%) developed hip displacement by the second radiograph examination. During follow-up radiographic examinations, 20 of the 30 children (66.7%) were diagnosed with hip displacement and/or dislocation of at least 1 side, and 10 of the 30 (33.3%) remained normal. Among 30 affected patients, 13 (43.3%) had hip displacement on the right side and 9 (30%) on the left side. Logistic regression analysis revealed that spasticity (P = .0033; OR, 15.9) and ophthalmologic abnormalities (P = .0163; OR, 16.9) were associated with hip dislocation during follow-up. CONCLUSIONS: Pelvic radiographic follow-up for all children with CZS will complement physical examination, diagnosis, and monitoring for hip joint deformities.

Limitation of cytology and the impact on reduction of cervical cancer / Limitação da citologia e o impacto na redução do câncer de colo uterino

Introduction: Cervical cancer is the third most common malignant tumor in the female population and the fourth cause of death from cancer in women in Brazil. The squamocolumnar junction and the transformation zone concentrate 90% of pre-invasive and invasive cervical lesions. Objective: To evaluate the prevalence of cytology without cells of the squamocolumnar junction and feasibility of active search. Methods: Cross-sectional study at a university hospital between 2017 and 2018. The prevalence of cytology without squamocolumnar junction cells was calculated. A convenience sample was obtained and mean age and relationship with presence of transformation zone cells were calculated. An active search was performed and cytology collected, with estrogen preparation if indicated. Medical records of the other women were analyzed. Results: Squamocolumnar junction cells were not found in 28.84% of samples. Mean age was 53 years, without association with presence of squamocolumnar junction cells (p=0.409). Seventy-six women returned, 36 of which (47.37%) used estrogen. Level 2 or 3 cervical intraepithelial neoplasia, microinvasive carcinoma or cancer was not identified. A total of 134 medical records were analyzed; only 36 women (26.87%) completed screening. Conclusions: The presence of squamocolumnar junction cells indicates quality of cytology; the use of estrogen in postmenopausal women favors its collection. There were difficulties in active search. An immediate repetition of cytology should be considered.

Retornaram 76 mulheres e 36 (47,37%) usaram estrogênio. Não identificamos neoplasia intraepitelial cervical graus 2 ou 3, carcinoma microinvasor e câncer. Analisados 134 prontuários, dos quais apenas 36 mulheres (26,87%) concluíram o rastreio. Conclusões: A presença de células da junção escamo-colunar indica qualidade da coleta, e o uso de estrogênio na pós-menopausa favorece sua obtenção. Houve dificuldade de busca ativa. A repetição imediata da citologia deve ser considerada.

Dietary Intake of Flaxseed Oil since Early Stages of Life Promotes Femur Quality in Male Rats.

BACKGROUND: Flaxseed oil (FO) is an alpha linolenic acid source important for growth and body development. However, there is little literature on the role of FO in critical stages of bone development and formation. OBJECTIVE: This study evaluated the influence of a diet containing FO on rat femurs. METHODS: After birth, mothers and pups were divided into control and flaxseed groups (n = 6 pups each) fed diets containing 7% soybean oil (C) or 7% FO. At 21 days, pups were weaned and separated from the mothers, and control or experimental diets were continued. At 67 days, the following were analyzed: osteocalcin and osteoprotegerin (OPG) levels, bone mineral density (BMD) and content, and bone area; the dimension, BMD, head radiodensity, and biomechanical proprieties of the right femur; and histomorphometric parameters of the left femur. RESULTS: Compared to the C group, the FO group presented (p < 0.05) a lower body mass (-3.7%) and medullary area (-10.1%) and higher osteocalcin (+36.7%), OPG (+52.5%), femur width (+3.8%), absolute mass (+2.3%), femur BMD (+3.6%), head radiodensity (+6.1%), maximum force (+7.4%), breaking strength (+17.3), and cortical thickness (+7.0). CONCLUSION: The FO diet contributed to femur quality in healthy male Wistar rats.

Evaluation of Chlamydia trachomatis and HR-HPV infection in women living with HIV: a cross-sectional study / Avaliação da infecção por Chlamydia trachomatis e HR-HPV em mulheres vivendo com HIV: um estudo transversal

Introduction: Infections caused by Chlamydia trachomatis (CT) and Human Papilloma Virus (HPV) are among the most prevalent sexually transmitted infections (STIs) worldwide. CT infection in women living with the human immunodeficiency virus (HIV) can facilitate HIV transmission by increasing HIV shedding in cervicovaginal secretions. The prevalence of Human papillomavirus (HPV) infection is higher in women living with HIV when compared to HIVnegative women, even when comparing those with the same sociodemographic characteristics. Generally, they have a high viral load and a higher persistence of viral infection, which increases the risk of developing premalignant and malignant lesions in the lower genital tract. Objective: To evaluate the frequency of CT and High-Risk HPV (HR-HPV) infection among women living with HIV and the association with sociodemographic, behavioral and clinical characteristics. Methods: Cross-sectional study carried out with a population of 66 non-pregnant women aged between 18 and 70 years living with HIV and/or acquired immunodeficiency syndrome (AIDS) at the Hospital Universitário Antônio Pedro, Universidade Federal Fluminense (UFF), Niterói (RJ), Brazil, between the period of March 1, 2018 and October 31, 2018. A standardized questionnaire was applied including sociodemographic and behavioral characteristics, and clinical information (use of oral contraceptives, Antiretroviral Therapy (ART), cluster of differentiation 4 (CD4) cell count, and viral load). Endocervical samples were collected for CT (COBAS 4800® system, Roche) and HPV (COBAS® HPV test, Roche) detection. Fisher's Exact Test was used to assess the association between variables. Regression analyses were performed using the logistic model in order to identify the factors associated with the outcomes of interest. Results: A frequency of 1.5% for CT and 21.2% for HR-HPV was found. Age was the single factor that presented statistical significance associated with HR-HPV infection. Conclusion: Our study showed that some women living with HIV promote risky behavior which could facilitate the acquisition of other STIs, such as HPV and CT infection. Some of them, with detected viral load, were not using condoms even with HIV-negative partners. These results may suggest that in addition to treatment and follow-up of women living with HIV, STIs counseling and guidance may play an important role in the control of STIs in this population

Introdução: As infecções causadas por Chlamydia trachomatis e por papilomavírus humano (HPV) estão entre as infecções sexualmente transmissíveis (IST) mais prevalentes em todo o mundo. A infecção por Chlamydia trachomatis em mulheres que vivem com HIV pode facilitar a transmissão do HIV, aumentando a disseminação do HIV cérvico-vaginal. A prevalência da infecção pelo HPV é maior em mulheres vivendo com HIV quando comparadas às mulheres HIV negativas, mesmo quando comparadas àquelas com as mesmas características sociodemográficas. Geralmente apresentam carga viral elevada e maior persistência de infecção viral, o que aumenta o risco de desenvolver lesões pré-malignas e malignas no trato genital inferior. Objetivo: Avaliar a frequência de infecção por Chlamydia trachomatis e HPV de alto risco (HR-HPV) em mulheres vivendo com HIV e sua associação com características sociodemográficas, comportamentais e clínicas. Métodos: Estudo transversal realizado com uma população de 66 mulheres não gestantes de 18 a 70 anos vivendo com HIV e/ou AIDS no Hospital Universitário Antônio Pedro, Universidade Federal Fluminense ­ Niterói (RJ), Brasil, entre 1º de março e 31 de outubro de 2018. Aplicou-se um questionário padronizado incluindo características sociodemográficas e comportamentais e informações clínicas (uso de anticoncepcionais orais, terapia antirretroviral, contagem de células CD4 e carga viral). Amostras endocervicais foram coletadas para detectar Chlamydia trachomatis (COBAS 4800® Roche) e HPV (COBAS ® HPV Roche). O teste exato de Fisher avaliou a associação entre as variáveis. As análises de regressão foram realizadas por meio do modelo logístico, a fim de identificar os fatores associados aos desfechos de interesse. Resultados: Encontrou-se frequência de 1,5% para Chlamydia trachomatis e 21,2% para HR-HPV. A idade foi o único fator que apresentou significância estatística associada à infecção por HR-HPV. Conclusão: Nosso estudo mostra que algumas mulheres vivendo com HIV praticam comportamentos de risco que podem facilitar a aquisição de outras IST, como a infecção por HPV e Chlamydia trachomatis. Algumas delas com carga viral detectada não usavam preservativo, mesmo com parceiros HIV negativos. Esses resultados podem sugerir que, além do tratamento e acompanhamento de mulheres vivendo com HIV, o aconselhamento e a orientação para IST podem desempenhar um papel importante no controle das IST nessa população.

Educating diabetic patients through an SMS intervention: a randomized controlled trial at a Brazilian public hospital

ABSTRACT Objective: Diabetes mellitus (DM) has a high healthcare system cost worldwide. Educational strategies are important to improve self-care and control this disease. This study aimed to evaluate satisfaction and clinical efficacy of a Short Message Service (SMS) educational intervention in self-care and nutrition at a Brazilian university hospital. Materials and methods: We conducted a trial of educational intervention and assigned eligible patients with DM to either receive weekly educational SMS for 6 months (intervention group [IG]) or no SMS at all (control group). A satisfaction questionnaire was applied before and after the intervention in both groups. Laboratory (fasting glucose, hemoglobin [Hb] A1c, total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein) and clinical (blood pressure) data were also collected. Data were analyzed using nonparametric tests with the Statistical Package for the Social Sciences. Results: We included 128 patients (64 in each group). Responses to the satisfaction questionnaire with self-care and healthcare professionals from 112 patients revealed an improvement in the perception of receiving information regarding helpful eating habits and in healthy eating behavior and an improvement in satisfaction with their diabetes care in the IG. In the post-intervention period, improved systolic blood pressure and HbA1c levels were observed in the IG as illustrated by delta % (post-intervention minus pre-intervention data divided by pre-intervention data multiplied by 100) reductions of 2.3% and 3.9%, respectively Conclusion: SMS intervention was useful as an educational tool for improving satisfaction and glycemic and blood pressure control of patients with DM observed at a Brazilian university hospital.

Pain assessment of preterm newborns in peripheral venipuncture and diaper changes / Avaliação da dor do recém-nascido pré-termo submetido a punção venosa periférica e a troca de fraldas

ABSTRACT BACKGROUND AND OBJECTIVES: Pain and stress are the main factors stimulating behavioral, physiological, and hormonal changes in preterm newborns (PTNB) admitted to a Neonatal Intensive Care Unit (NICU); therefore, the systematic multidimensional assessment of pain at the bedside becomes an essential tool for reducing the impact of brain stimulation, as it guides the appropriate treatment. The objectives of this study were to assess the pain at the bedside of PTNB submitted to peripheral venipuncture or diaper change and to describe the measures for pain relief. METHODS: Longitudinal study, with a prospective cohort of 25 PTNB, carried out in an NICU in the city of Rio de Janeiro. Pain assessment at the bedside was performed at three different times, using the Neonatal Infant Pain Scale (NIPS) and Premature Infant Pain Profile (PIPP), when subjected to peripheral venipuncture for infusion therapy and diaper changes. The scores of the scales were analyzed using the Chi-square test. RESULTS: In the puncture group, there was pain and increased intensity. In the diaper group, three PTNB showed pain at the third assessment. During peripheral venipuncture, the non-pharmacological measures were used: oral 25% glucose, non-nutritive suction and a combination of the two. CONCLUSION: Assessing pain at the bedside using scales helps nursing professionals in pain prevention and treatment, avoiding altered responses of newborns in the face of procedures.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor e o estresse são os principais fatores de estímulo às alterações comportamentais, fisiológicas e hormonais dos recém-nascidos pré-termos (RNPT) internados na Unidade de Terapia Intensiva Neonatal (UTIN); portanto, a avaliação multidimensional sistemática da dor se torna uma ferramenta imprescindível para a redução do impacto da estimulação cerebral, visto que direciona para o adequado tratamento. Os objetivos deste estudo foram avaliar a dor à beira do leito de RNPT submetidos à punção venosa periférica ou à troca de fraldas e descrever as medidas para o alívio da dor. MÉTODOS: Estudo longitudinal, com uma coorte prospectiva de 25 RNPT, realizado em uma UTIN no município do Rio de Janeiro. Foi realizada avaliação da dor à beira do leito em três momentos distintos, com a Neonatal Infant Pain Scale e Premature Infant Pain Profile, quando submetidos à punção venosa periférica para terapia infusional e troca de fraldas. As pontuações das escalas foram analisadas por meio do teste Qui-quadrado. RESULTADOS: No grupo punção, houve presença de dor e aumento da intensidade. No grupo fralda, três RNPT mostraram presença de dor na terceira avaliação. Durante a punção venosa periférica, foram utilizadas as medidas não farmacológicas; glicose oral a 25%, sucção não nutritiva e a combinação das duas. CONCLUSÃO: A avaliação da dor à beira do leito por meio de escalas auxilia os profissionais de enfermagem na prevenção e tratamento da dor, evitando respostas alteradas do recém-nascido diante de procedimentos.

Folinic acid rescue during methotrexate treatment for low-risk gestational trophoblastic neoplasia - How much is just right?

OBJECTIVE: To compare the outcomes of patients with low-risk gestational trophoblastic neoplasia (GTN) treated with 8-day methotrexate (MTX) with two different regimens of folinic acid (FA). METHODS: Retrospective cohort study of low-risk GTN followed at Rio de Janeiro Federal University, from January/2000-December/2019 with 8-day MTX with FA at 0.1 mg/kg versus 15 mg fixed dose. RESULTS: Among 667 patients with low-risk GTN, 323 were treated with FA at 0.1 mg/kg and 142 with FA at 15 mg fixed dose. The weight-based and fixed dose groups were comparable in terms of clinical profile but did differ in the hCG pretreatment level (8883 versus 5127 IU/L, p < 0.01) and FIGO risk score 5/6 (3.4% versus 18.3%, p < 0.01), respectively. Despite this, there was no difference in the remission rate in first-line treatment (76.8 versus 81%, p = 0.33), although FA at 0.1 mg/kg had a significantly higher number of chemotherapy cycles to remission (5 versus 4, p < 0.01), need to delay chemotherapy due to toxicity (6.8 versus 2.8%, p < 0.01) and time to remission, (12 versus 8 weeks, p < 0.01), respectively. A logistic regression analysis showed that the different FA rescue regimens appeared comparable in terms of achieving remission in first-line chemotherapy for low-risk GTN (OR:5.16, CI95%:0.84-31.64, p = 0.08). CONCLUSION: FA with 15 mg fixed dose as compared to 0.1 mg/kg of FA was associated with similar primary remission rate, relapse or death among low-risk GTN treated with 8-day MTX. This regimen is highly practical, reduces visits to health facilities, appears equally safe and may be preferable with the 8-day MTX regimen in the treatment of low-risk GTN.

Data were analyzed using nonparametric tests with the Statistical Package for the Social Sciences. RESULTS: We included 128 patients (64 in each group). Responses to the satisfaction questionnaire with self-care and healthcare professionals from 112 patients revealed an improvement in the perception of receiving information regarding helpful eating habits and in healthy eating behavior and an improvement in satisfaction with their diabetes care in the IG. In the post-intervention period, improved systolic blood pressure and HbA1c levels were observed in the IG as illustrated by delta % (post-intervention minus pre-intervention data divided by pre-intervention data multiplied by 100) reductions of 2.3% and 3.9%, respectively. CONCLUSION: SMS intervention was useful as an educational tool for improving satisfaction and glycemic and blood pressure control of patients with DM observed at a Brazilian university hospital.

Effect of glucose and non-nutritive sucking on puncture pain in premature infants: a crossover clinical trial. / Efeito da glicose e sucção não nutritiva na dor de prematuros na punção: ensaio clínico crossover.

OBJECTIVE: To compare the effect of non-nutritive sucking, 25% oral glucose and 25% oral glucose combined with non-nutritive sucking in pain relief in premature infants submitted to heel puncture for blood glucose monitoring. METHOD: This is a randomized crossover clinical trial with 34 preterm infants who randomly received interventions: non-nutritive sucking, 25% oral glucose and the two interventions combined for three consecutive days in heel puncture for blood glucose monitoring. Assessment by the Premature Infant Pain Profile for 30 seconds before the intervention, called the baseline period and for 5 minutes after puncture. RESULTS: The combination of interventions made the premature infants return to baseline, with 1 minute and 30 seconds after heel puncture, promoting a 2.2% percentage reduction in the scale. CONCLUSION: Comparing the effect of isolated and combined interventions showed that, when offered in combination, preterm infants were able to return to baseline parameters more quickly.

Predictors for single-agent resistance in FIGO score 5 or 6 gestational trophoblastic neoplasia: a multicentre, retrospective, cohort study.

BACKGROUND: Patients with gestational trophoblastic neoplasia who have an International Federation of Gynaecology and Obstetrics (FIGO) risk score of 5 or 6 usually receive non-toxic single-agent chemotherapy as a first-line treatment. Previous studies suggest that only a third of patients have complete remission, with the remaining patients requiring toxic multiagent chemotherapy to attain remission. As stratification factors are unknown, some centres offer multiagent therapy upfront, resulting in overtreatment of many patients. We aimed to identify predictive factors for resistance to single-agent therapy to inform clinicians on which patients presenting with a FIGO score of 5 or 6 are likely to benefit from upfront multiagent chemotherapy. METHODS: We did a multicentre, retrospective, cohort study of patients with gestational trophoblastic neoplasia presenting with a FIGO score of 5 or 6, who received treatment at three gestational trophoblastic neoplasia reference centres in the UK, Brazil, and the USA between Jan 1, 1964, and Dec 31, 2018. All patients who had been followed up for at least 12 months after remission were included. Patients were excluded if they had received a non-standard single-agent treatment (eg, etoposide); had been given a previously established first-line multiagent chemotherapy regimen; or had incomplete data for our analyses. Patient data were retrieved from medical records. The primary outcome was the incidence of chemoresistance after first-line or second-line single-agent chemotherapy. Variables associated with chemoresistance to single-agent therapies were identified by logistic regression analysis. In patient subgroups defined by choriocarcinoma histology and metastatic disease status, we did bootstrap modelling to define thresholds of pretreatment human chorionic gonadotropin concentrations and identify groups of patients with a greater than 80% risk (ie, a positive predictive value [PPV] of 0·8) of resistance to single-agent chemotherapy. FINDINGS: Of 5025 patients with low-risk gestational trophoblastic neoplasia, we identified 431 patients with gestational trophoblastic neoplasia presenting with a FIGO risk score of 5 or 6. All patients were followed up for a minimum of 2 years. 141 (40%) of 351 patients developed resistance to single-agent treatments and required multiagent chemotherapy to achieve remission. Univariable and multivariable logistic regression revealed metastatic disease status (multivariable logistic regression analysis, odds ratio [OR] 1·9 [95% CI 1·1-3·2], p=0·018), choriocarcinoma histology (3·7 [1·9-7·4], p=0·0002), and pretreatment human chorionic gonadotropin concentration (2·8 [1·9-4·1], p<0·0001) as significant predictors of resistance to single-agent therapies. In patients with no metastatic disease and without choriocarcinoma, a pretreatment human chorionic gonadotropin concentration of 411 000 IU/L or higher yielded a PPV of 0·8, whereas in patients with either metastases or choriocarcinoma, a pretreatment human chorionic gonadotropin concentration of 149 000 IU/L or higher yielded the same PPV for resistance to single-agent therapy. INTERPRETATION: Approximately 60% of women with gestational trophoblastic neoplasia presenting with a FIGO risk score of 5 or 6 achieve remission with single-agent therapy; almost all remaining patients have complete remission with subsequent multiagent chemotherapy. Primary multiagent chemotherapy should only be given to patients with metastatic disease and choriocarcinoma, regardless of pretreatment human chorionic gonadotropin concentration, or to those defined by our new predictors.

Diagnosis of pulmonary tuberculosis in children and adolescents: comparison of two versions of the Brazilian Ministry of Health scoring system.

The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.
