RESUMO

OBJECTIVE: Necrotizing enterocolitis (NEC) classically is diagnosed by radiographic demonstration of pneumatosis intestinalis/portal venous gas (PI/PVG). This study examines clinical characteristics of NEC confirmed by independent evaluation of abdominal radiographs, taken for clinical signs of NEC, or by pathologic findings at laparotomy or autopsy (confirmed NEC [cNEC]). STUDY DESIGN: The investigated cohort included 1,382 extremely low birth weight (BW) infants (BW range: 500-1,000 g) with median 27 weeks (range: 23-32) gestational age (GA) at birth. They were randomized into the placebo-controlled "Connection Trial" of the new biological drug candidate IBP-9414 with cNEC as one primary endpoint. RESULTS: Total 119 infants (8.6%) had cNEC diagnosed at median 14 days of age by confirming PI/PVG at X-ray adjudication (n = 111) and/or by surgery/autopsy (n = 21). Sixteen percent of cNEC cases died. Adverse events of NEC were reported in 8.5% of infants and 4.1% had NEC diagnosed by radiology and surgery/autopsy at the participating centers. Regression analyses showed that the risk of cNEC decreased by 11 to 30% for every 100-g increment in BW and single-week increment in GA and associated cNEC with odds ratios (ORs) > 2.0 for gastrointestinal (GI) perforation and obstruction, hypotension, hypokalemia, hypophosphatemia, and death. Comparing risks of cNEC in infants below and above 750-g BW showed higher ORs (2.7-4.3) for GI perforation, hypotension, hypokalemia, and renal complications in the smaller infants, whereas the bigger infants had higher ORs (1.9-3.2) for serious non-GI events, late-onset sepsis (LOS), and death. Predictors of cNEC (hazard ratio, HR > 1.5) included serious non-GI events (mainly infections), hyponatremia, and hyperglycemia, whereas the HR was 0.52 for intravenous antibiotics. After cNEC diagnosis, there were higher rates of GI perforation and obstruction, hypotension, hypokalemia, and LOS. CONCLUSION: Independent adjudication of abdominal radiographs increased radiological recognition of NEC and proved to be feasible in a multicenter study setting as well as able to diagnose clinically relevant NEC. KEY POINTS: · Independent adjudication of abdominal radiographs in ELBW infants increased NEC recognition.. · Risk of NEC decreased by 11 to 30% with every 100-g increment in BW and GA week.. · In infants with BW 750 to 1,000 g, the risk of death from NEC was almost twice that in infants with BW 500 to 749 g. · Infants with NEC received antibiotics during one-third and parenteral nutrition during half of the first 7 postnatal weeks..

RESUMO

The malignant transformation of mature cystic teratomas during pregnancy is a rare occurrence in medical literature. In this case report, we present a remarkable instance of mucinous intestinal adenocarcinoma arising from a mature ovarian cystic teratoma diagnosed during pregnancy. This is among the few reports detailing the effective use of the FOLFOX 6 chemotherapy regimen for treating this type of intestinal cancer. Furthermore, we emphasize the immunohistochemical results that confirm the colorectal histological origin.

RESUMO

OBJECTIVE: We sought to identify clinical and demographic factors associated with gastrostomy tube (g-tube) placement in periviable infants. STUDY DESIGN: We conducted a single-center retrospective cohort study of live-born infants between 22 and 25 weeks' gestation. Infants not actively resuscitated and those with congenital anomalies were excluded from analysis. RESULTS: Of the 243 infants included, 158 survived until discharge. Of those that survived to discharge, 35 required g-tube prior to discharge. Maternal race/ethnicity (p = 0.006), intraventricular hemorrhage (p = 0.013), periventricular leukomalacia (p = 0.003), bronchopulmonary dysplasia (BPD; p ≤ 0.001), and singleton gestation (p = 0.009) were associated with need for gastrostomy. In a multivariable logistic regression, maternal Black race (Odds Ratio [OR] 2.88; 95% confidence interval [CI] 1.11-7.47; p = 0.029), singleton gestation (OR 3.99; 95% CI 1.28-12.4; p = 0.017) and BPD (zero g-tube placement in the no BPD arm; p ≤ 0.001) were associated with need for g-tube. CONCLUSION: A high percentage of periviable infants surviving until discharge require g-tube at our institution. In this single-center retrospective study, we noted that maternal Black race, singleton gestation, and BPD were associated with increased risk for g-tube placement in infants born between 22 and 25 weeks' gestation. The finding of increased risk with maternal Black race is consistent with previous reports of racial/ethnic disparities in preterm morbidities. Additional studies examining factors associated with successful achievement of oral feedings in preterm infants are necessary and will inform future efforts to advance equity in newborn health. KEY POINTS: · BPD, singleton birth, and Black race are associated with need for g-tube in periviable infants.. · Severe intraventricular hemorrhage is associated with increased mortality or g-tube placement in periviable infants.. · Further investigation into the relationship between maternal race and g-tube placement is warranted..

RESUMO

While the first 1,000 days of life are a critical period in child's development, limited information on the main determinants affecting this period in the Latin America and the Caribbean (LAC) region is available. Therefore, the Latin American Pediatric Infectious Diseases Society (SLIPE) held an ad hoc workshop in May 2022 with an expert panel designed to analyze the main factors impacting the development of childhood in the region during this period and the main causes of maternal infant morbimortality. The aim was to identify priorities, generate recommendations, and advise practical actions to improve this situation. Considerations were made about the challenges involved in bridging the gap that separates the region from more developed countries regarding an optimal early childhood and maternal care. Extensive discussion was conducted to reach consensus recommendations on general strategies intended to reduce maternal and infant mortality associated with infections and immune-preventable diseases during the first 1,000 days of life in LAC.

RESUMO

This article presents attitudes and practices regarding COVID-19 vaccination in the South American population. The study collected data from a self-administered survey distributed through social media platforms between February and April 2022 (N = 6555). The survey included questions related to participants' sociodemographic background, flu vaccination practices, sources of information about COVID-19, and opinions regarding pandemic management and vaccination against SARS-CoV-2. The respondents agreed with the statement that COVID-19 vaccines were necessary (86.4%), effective (79.8%), safe (79.1%), and should be mandatory (64%). Overall, 83.4% accepted vaccination and 12.3% refused it completely. Main rejection reasons were safety (65.8%) and efficacy (54.9%) issues, and rushed development and approvals (49.1%). Vaccine uptake was associated with being ≥60 years, being a healthcare worker, previous influenza vaccine uptake, adherence to preventive measures, the death of ≥1 close people from COVID-19, and being informed through mass media or health authorities' channels. Vaccine uptake inversely correlated with male gender, low educational level, and use of closed social networks for COVID-19 information purposes. This study provides valuable insights into COVID-19 vaccination attitudes and practices in South America that may be used to promote vaccine uptake in the region. Higher COVID-19 vaccination acceptance among people with previously acquired prevention habits reinforces the importance of routine health promotion strategies.

RESUMO

The Global Health Consortium at Florida International University developed an end-to-end solution framework based on the input of a diverse panel of experts from middle-income country (MIC) government agencies, public health think tanks, academia, and nonprofit organizations to identify mechanisms to help MIC governments and stakeholders increase access to novel vaccines for infectious diseases. The resultant layout can be deployed to improve vaccine discovery and development, strengthen regulatory processes, and boost vaccine production, access, and implementation. Mechanisms include policies and incentives MIC governments can use to stimulate vaccine investment and activity, as well as actions government agencies can take together with other stakeholders to coordinate efforts or build capabilities. Through a series of individual virtual interviews, we engaged diverse experts from MIC government agencies, public health think tanks, academia, and nonprofit organizations who understand the vaccine ecosystem, immunization policies, and population health financing at global, regional, and country levels. Responses were mapped, and in-depth questions were prepared for a group virtual discussion. This paper is the result of such a group discussion. The panel identified clear opportunities for MICs to improve locally-driven innovations and future access to novel vaccines. It proposes a solution framework for countries considering investing in vaccine research and development and innovation to use as a guide to evaluate the steps they could take to improve such an environment and incentivize innovation in vaccine development. It is hoped that this end-to-end solution framework will become a key resource to help MICs strengthen policies and take more actions to make such improvements.

RESUMO

Chagas disease, also known as American trypanosomiasis, is caused by Trypanosoma cruzi, a parasite transmitted by hematophagous triatomine insects (subfamily Triatominae) belonging to the Reduviidae family, order Hemiptera. Infection occurs through contact with the feces of the infected vector at the site of its bite or on intact mucosa. [Pediatr Ann. 2023;52(10):e394-e397.].

RESUMO

Lower urinary tract obstruction (LUTO) is a rare birth defect with a prevalence between 1 in 5,000 and 1 in 25,000 pregnancies. LUTO is one of the most common causes of congenital abnormalities of the renal tract. Several genetic conditions have been associated with LUTO. Most common causes of LUTO are posterior urethral valves and urethral atresia. Despite available prenatal and postnatal treatments, LUTO is a significant cause of morbidity and mortality in newborns causing significant end stage renal disease and pulmonary hypoplasia.

RESUMO

Three Colombian patients with chronic HTLV-1 infection and severe intermediate and/or posterior uveitis are described. In one case, retinal ablation was necessary due to extensive peripheral degeneration, while the other two were successfully managed with local anti-inflammatory therapy. Gradual resolution of ocular findings was observed in all three patients on follow-up. Uveitis is a rarely recognized late complication of this infection, which represents a diagnostic and therapeutic challenge for clinicians in endemic countries. The real extension of HTLV-1 prevalence in Colombia and the frequency of its ophthalmologic complications remain to be determined.

RESUMO

OBJECTIVE: Despite improvements in our ability for early diagnosis and providing supportive care for infants with gastroschisis, it continues to be associated with long length of stay and morbidity. Intestinal dysfunction secondary to chronic inflammatory insult to exposed bowel is well known; however, little research has been done on the impact of acute inflammation in the perinatal period on intestinal function. This study's aim was to investigate the impact of acute chorioamnionitis on the time to achieve full enteral feeds and length of hospital stay. STUDY DESIGN: Retrospective chart review of 60 mothers and their infants born with gastroschisis at a Level IV NICU from November 2011 to June 2020 was performed. Infants were divided into two groups based on the presence of histologic chorioamnionitis, and outcomes were compared. The primary outcome was delayed full enteral feeds (full enteral feeds after 28 days of life). The secondary outcomes were differences in their time to achieve full enteral feeds and time to hospital discharge, and prolonged length of hospital stay (discharge after 30 days of life). Univariate and multivariate logistic regression analyses were performed to assess the association between the dependent and the predictor variables. RESULT: Of the 60 infants enrolled, 23 (38%) had evidence of histologic chorioamnionitis. The median gestational age was 37 weeks. Fifty-four (90%) infants achieved full enteral feeds, with a median time of 24 days. Median length of hospital stay was 31 days. The presence of histologic chorioamnionitis was not associated with delayed full enteral feeds (odds ratio [OR] = 0.79; 95% confidence interval [CI] = 0.14-4.23; p = 0.80) or prolonged length of hospital stay (OR = 0.45; 95% CI = 0.1-0.23; p = 0.32) in the adjusted analysis. CONCLUSION: Acute placental inflammation during the perinatal period does not impact the infant's time to achieve full feeds or prolong their hospital stay. Larger studies are needed to confirm these findings. KEY POINTS: · Chronic inflammatory injury to exposed bowel in utero is well known in fetuses with gastroschisis.. · Acute inflammatory injury during perinatal period may impact enteral feeding outcomes.. · No impact of acute placental inflammation on time to full enteral feeds..

RESUMO

BACKGROUND: Malaria-endemic areas are not spared from the impact of coronavirus disease 2019 (COVID-19), leading to co-infection scenarios where overlapping symptoms impose serious diagnostic challenges. Current knowledge on Plasmodium spp. and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) co-infection in pregnant women remains limited, especially in Latin America, where Plasmodium vivax infection is highly prevalent. METHODS: This is a case series of five pregnant women with P. vivax and SARS-CoV-2 co-infection hospitalized in two main malaria referral centers of the Capital District and Bolivar state, Venezuela between March 13, 2020 and December 31, 2021. RESULTS: Clinical and laboratory data from five pregnant women with a mean age of 22 years were analyzed; three of them were in the third trimester of pregnancy. Comorbidities included obesity in two cases, hypertension in one, and asthma in one. Three out of five patients had severe to critical COVID-19 disease. Dry cough, fever, chills, and headache were the most frequent symptoms reported. Laboratory analyses showed elevated aspartate/alanine aminotransferase and creatinine levels, thrombocytopenia, and severe anemia as the most relevant abnormalities. The mean period between symptom onset and a positive molecular test for SARS-CoV-2 infection or positive microscopy for Plasmodium spp. was 4.8 ± 2.5 days and 2.8 ± 1.6 days, respectively. The mean hospital stay was 5.4 ± 7 days. Three women recovered and were discharged from the hospital. Two women died, one from cerebral malaria and one from respiratory failure. Three adverse fetal outcomes were registered, two miscarriages and one stillbirth. CONCLUSION: This study documented a predominance of severe/critical COVID-19 disease and a high proportion of adverse maternal-fetal outcomes among pregnant women with malaria and COVID-19 co-infection. More comprehensive prospective cohort studies are warranted to explore the risk factors, management challenges, and clinical outcomes of pregnant women with this co-infection.

RESUMO

Background: Flaviviruses are agents with high zoonotic potential of importance to human health. They are transmitted by mosquitoes of the Culicidae family, and birds act as host-amplifiers. Birds, mammals, and humans are susceptible hosts to infection. Methods: In this study, West Nile virus (WNV), flavivirus, infection was studied in 37 serum samples from 22 hens on Easter Island, Chile. Results: WNV was detected by ELISA (ID Screen® West Nile Competition Multi-Species). We report absence of antibodies to WNV, and to related viruses of the Japanese Encephalitis Virus serocomplex, and, therefore, absence of infection across the sample. Conclusion: This is the first evaluation of its type carried out in Chile, and represents a positive result for public health at Easter Island.

RESUMO

BACKGROUND/OBJECTIVE: This study aims to describe the course and to identify poor prognostic factors of SARS-CoV-2 infection in patients with rheumatic diseases. METHODS: Patients ≥ 18 years of age, with a rheumatic disease, who had confirmed SARS-CoV-2 infection were consecutively included by major rheumatology centers from Argentina, in the national, observational SAR-COVID registry between August 13, 2020 and July 31, 2021. Hospitalization, oxygen requirement, and death were considered poor COVID-19 outcomes. RESULTS: A total of 1915 patients were included. The most frequent rheumatic diseases were rheumatoid arthritis (42%) and systemic lupus erythematosus (16%). Comorbidities were reported in half of them (48%). Symptoms were reported by 95% of the patients, 28% were hospitalized, 8% were admitted to the intensive care unit (ICU), and 4% died due to COVID-19. During hospitalization, 9% required non-invasive mechanical ventilation (NIMV) or high flow oxygen devices and 17% invasive mechanical ventilation (IMV). In multivariate analysis models, using poor COVID-19 outcomes as dependent variables, older age, male gender, higher disease activity, treatment with glucocorticoids or rituximab, and the presence of at least one comorbidity and a greater number of them were associated with worse prognosis. In addition, patients with public health insurance and Mestizos were more likely to require hospitalization. CONCLUSIONS: In addition to the known poor prognostic factors, in this cohort of patients with rheumatic diseases, high disease activity, and treatment with glucocorticoids and rituximab were associated with worse COVID-19 outcomes. Furthermore, patients with public health insurance and Mestizos were 44% and 39% more likely to be hospitalized, respectively. STUDY REGISTRATION: This study has been registered in ClinicalTrials.gov under the number NCT04568421. Key Points • High disease activity, and treatment with glucocorticoids and rituximab were associated with poor COVID-19 outcome in patients with rheumatic diseases. • Some socioeconomic factors related to social inequality, including non-Caucasian ethnicity and public health insurance, were associated with hospitalization due to COVID-19.

RESUMO

Moving towards a sustainable society implies constant improvement in the way energy is supplied and consumed, with wider implementation of solar and wind energy facilities in stand-alone or hybrid configurations. The goal of this work is to evaluate the lifecycle performance (construction and operation-related impact) of large-scale solar and wind energy systems and to compare it with conventional coal and natural gas fossil fuel plants under similar conditions. Environmental analyses of energy conversion systems today usually neglect the construction-related environmental impact of fossil fuel plants, because it is significantly smaller than the impact related to the operation of the plant. However, the construction of large-scale renewable plants implies the use of rare materials, transport-related emissions, and other environmentally impactful activities. The plants evaluated here are configured and compared for similar emissions and similar power output. It is found that the life-cycle environmental impact of the renewable plants could, in some specific cases, exceed that of the fossil fuel plants. Understanding the reasons behind this and the possible limitations of the different technologies can help plan for sustainable energy systems in the future. Finally, solutions to minimize the impact of renewable energy are proposed for more environmentally friendly implementation and future research.

RESUMO

OBJECTIVE: The objective of our study was to compare the maternal and neonatal complications of periviable birth by the delivery route. STUDY DESIGN: A retrospective cohort study of periviable deliveries (220/7-256/7weeks) from 2013 to 2020 at a tertiary teaching institution was conducted. Deliveries were grouped by the mode of delivery. Excluded deliveries included pregnancy termination, anomaly, or undesired neonatal resuscitation. The primary composite maternal outcome included death, intensive care admission, sepsis, surgical site infection, unplanned operation, or readmission. Secondary outcomes included maternal blood loss, length of stay, neonatal survival, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), patent ductus arteriosus (PDA), and retinopathy of prematurity (ROP). Outcomes were compared using Student's t-test, Wilcoxon-Mann-Whitney and Chi-squared tests. Relative risk (RR) and 95% confidence intervals were calculated with log-binomial regression. p-Values <0.05 were considered significant. Demographic and intervention variables associated with the outcome and the exposure were included in an adjusted relative risk (aRR) model. Subgroup analyses of singleton pregnancies and 220/7 to 236/7 weeks deliveries were conducted. RESULTS: After exclusion, 230 deliveries were included in the cohort. Maternal characteristics were similar between cohorts. For the primary outcome, cesarean delivery was associated with a trend toward increased maternal morbidity (22.6 vs. 10.7%, RR = 2.11 [1.03-4.43], aRR = 1.95 [0.94-4.03], p-value 0.07). Administration of magnesium sulfate, antenatal corticosteroids, and tocolytics were similar between cohorts. Neonatal survival to discharge was not different between the groups (54/83, 65.1% vs. 118/191, 61.8%, aRR = 0.93 [0.77-1.13]). Among the 172 neonates discharged alive, there was no difference in BPD, IVH, NEC, PDA, ROP, or intact survival. CONCLUSION: Periviable birth has a high rate of maternal morbidity with a trend toward the highest risk among women undergoing cesarean delivery. These risks should be included in shared decision-making. KEY POINTS: · Periviable birth has high maternal morbidity (19%) and is highest after cesarean delivery (23%).. · Route of delivery does not impact neonatal survival or intact neonatal survival.. · Head entrapment is rare during vaginal breech delivery..
