Neonatal invasive candidiasis in low- and middle-income countries: Data from the NeoOBS study.

Neonatal invasive candidiasis (NIC) has significant morbidity and mortality. Reports have shown a different profile of those neonates affected with NIC and of fluconazole-resistant Candida spp. isolates in low- and middle-income countries (LMICs) compared to high-income countries (HICs). We describe the epidemiology, Candida spp. distribution, treatment, and outcomes of neonates with NIC from LMICs enrolled in a global, prospective, longitudinal, observational cohort study (NeoOBS) of hospitalized infants <60 days postnatal age with sepsis (August 2018-February 2021). A total of 127 neonates from 14 hospitals in 8 countries with Candida spp. isolated from blood culture were included. Median gestational age of affected neonates was 30 weeks (IQR: 28-34), and median birth weight was 1270 gr (interquartile range [IQR]: 990-1692). Only a minority had high-risk criteria, such as being born <28 weeks, 19% (24/127), or birth weight <1000 gr, 27% (34/127). The most common Candida species were C. albicans (n = 45, 35%), C. parapsilosis (n = 38, 30%), and Candida auris (n = 18, 14%). The majority of C. albicans isolates were fluconazole susceptible, whereas 59% of C. parapsilosis isolates were fluconazole-resistant. Amphotericin B was the most common antifungal used [74% (78/105)], followed by fluconazole [22% (23/105)]. Death by day 28 post-enrollment was 22% (28/127). To our knowledge, this is the largest multi-country cohort of NIC in LMICs. Most of the neonates would not have been considered at high risk for NIC in HICs. A substantial proportion of isolates was resistant to first choice fluconazole. Understanding the burden of NIC in LMIC is essential to guide future research and treatment guidelines.

Our study describes neonates from low- and middle-income countries with neonatal invasive candidiasis (NIC). Most of them were outside the groups considered at high risk for NIC described in high-income countries. Candida spp. epidemiology was also different. The mortality was high (22%). Further research in these settings is required.

Vaccination in Pediatric Patients with Sickle-Cell Disease: Uptake Report and Mini-Review.

BACKGROUND: Brazil has one of the highest numbers of births with sickle-cell disease (SCD) in the Americas. Despite the risk of severe illnesses and death due to both vaccine-preventable infections, vaccination uptake in pediatric patients with SCD is unknown. MATERIAL AND METHODS: Children under 18 years with SCD presenting to routine medical consultations had their vaccination status evaluated according to the national recommendations. Data obtained were classified as 'Adequate', 'Delayed' or 'Missing' vaccination and compared among age groups. RESULTS: From 117 children screened, 100 had their vaccination card available. Vaccination coverage of routine vaccines was above 95% for all primary series and both age groups, with varied rates of delays and low missing doses. Among SCD extended vaccination, the most frequently delayed and missed vaccines were those specifically recommended to individuals with SCD as per national guidelines-and particularly those against encapsulated bacteria. Significant and varied rates of missing doses occurred in primary series and booster doses for PPSV23, Hib, menC, hepatitis A and varicella. The average influenza vaccination rate was 69.5%, with higher rates among younger children. CONCLUSIONS: Children with SCD have alarming under-vaccination rates. Basic prevention strategies in Brazil should be reassessed in this specific population.

High prevalence of SARS-CoV-2 infection among symptomatic healthcare workers in a large university tertiary hospital in São Paulo, Brazil.

BACKGROUND: Brazil became the epicenter of the COVID-19 pandemic in Latin America since May 2020, reporting the highest number of cases and deaths in the region. Healthcare workers (HCWs) are at increased risk of SARS-CoV-2 infection, experiencing a significant burden from COVID-19. Identifying and understanding the clinical characteristics and risk factors associated with infection are of paramount importance to inform screening strategies and infection control practices in this scenario. The aims of this study were to investigate the prevalence and clinical characteristics of HCWs with COVID-19 symptoms. METHODS: Between March 21st and May 22nd, 2020 a cross-sectional study was performed in a tertiary university hospital in São Paulo. Prevalence of SARS-CoV-2 infection among HCWs with COVID-19 symptoms was determined by RT-PCR testing on nasopharyngeal and oropharyngeal samples. Participants were asked to complete an electronic structured questionnaire including clinical and demographic data. RESULTS: Overall, 125 (42.37%) of 295 symptomatic HCWs tested positive for SARS-CoV-2. Over the 10-week study period, positivity rates varied from 22.2% (95% CI 15.9-60.3%) in the second week to 55.9% (95% CI 43.2-68.6%) in the sixth week, reaching a plateau (38-46%) thereafter. Median (SD) age was 34.2 (9.9) years and 205 (69.5%) were female. We did not find significant differences in the prevalence of the most commonly reported underlying medical condition among healthcare workers that tested positive or negative for SARS-CoV-2 infection. After multivariable analysis, using logistic regression, anosmia (adjusted OR 4.4 95% CI 2.21-8.74) and ocular pain (adjusted OR 1.95 95% CI 1.14-3.33) were the only symptoms independently associated with positivity for SARS-CoV-2 infection. Follow-up information on clinical outcomes showed that 9 (7.2%) HCWs were hospitalized (seven were male) and 2 (1.6%) died. CONCLUSIONS: The findings of this study confirmed the high burden of SARS-CoV-2 infection among healthcare workers in the hardest hit city by the pandemic in Latin America. Anosmia and ocular pain were symptoms independently associated with COVID-19 diagnosis. In low and middle-income countries, where limited availability of tests is frequent, these findings may contribute to optimize a targeted symptom-oriented screening strategy.

Lower cost alternatives for molecular diagnosis of COVID-19: conventional RT-PCR and SYBR Green-based RT-qPCR.

In March 2020, WHO declared a pandemic state due to SARS-CoV-2 having spread. TaqMan-based real-time RT-qPCR is currently the gold standard for COVID-19 diagnosis. However, it is a high-cost assay, inaccessible for the majority of laboratories around the world, making it difficult to diagnose on a large scale. The objective of this study was to standardize lower cost molecular methods for SARS-CoV-2 identification. E gene primers previously determined for TaqMan assays by Colman et al. (2020) were adapted in SYBR Green assay and RT-PCR conventional. The cross-reactivity test was performed with 17 positive samples for other respiratory viruses, and the sensibility test was performed with 8 dilutions (10 based) of SARS-CoV-2 isolated and 63 SARS-CoV-2-positive samples. The SYBR Green assays and conventional RT-PCR have not shown amplification of the 17 respiratory samples positives for other viruses. The SYBR Green-based assay was able to detect all 8 dilutions of the isolate. The conventional PCR detected until 107 dilution, both assays detected the majority of the 63 samples, 98.42% of positivity in SYBR Green, and 93% in conventional PCR. The average Ct variation between SYBR Green and TaqMan was 1.92 and the highest Ct detected by conventional PCR was 35.98. Both of the proposed assays are less sensitive than the current gold standard; however, our data shows a low sensibility variation, suggesting that these methods could be used by laboratories as a lower cost molecular method for SARS-CoV-2 diagnosis.

Living with CHD: quality of life (QOL) in early adult life.

AIMS: The aim of this study was to assess the quality of life, psychiatric morbidity, and the psychosocial adjustment of adolescents and young adults with CHD, and determine which variables play a role in buffering stress and promoting resilience and which ones have a detrimental effect; and to investigate the situation on school performance and failures, social and family support, physical limitations, and body image of these patients. METHODS: The study enrolled 137 CHD patients (79 male), with age ranging from 12 to 26 years old (M=17.60±3.450 years). The patients were interviewed regarding social support, family educational style, self-image, demographic information, and physical limitations. They responded to questions in a standardised psychiatric interview (SADS-L) and completed self-reported questionnaires for the assessment of quality of life (WHOQOL-BREF) and psychosocial adjustment (YSR/ASR). RESULTS: We found a 19.7% lifetime prevalence of psychopathology in our patients (27.6% in female and 13.9% in male). Of them, 48% had retentions in school (M=1.61 year±0.82). The perception of quality of life in CHD patients is better compared with the Portuguese population in the social relationships and environmental dimensions. However, it is worse in complex forms of CHD than in moderate-to-mild ones, in cyanotic versus acyanotic patients, in moderate-to-severe versus mild residual lesions, in patients submitted versus those not submitted to surgery, in patients with versus without physical limitations, and patients who have need for medication versus those who do not. Social support is very important in improving quality of life of patients in all dimensions as well as academic performance. CONCLUSIONS: Female patients and patients with poor academic performance and poor social support have worse psychosocial adjustment and perception of quality of life.

Impact of fetal development on neurocognitive performance of adolescents with cyanotic and acyanotic congenital heart disease.

BACKGROUND: Our aims were to evaluate the neurocognitive performance in adolescents with congenital heart disease (CHD) and to determine whether parameters of fetal development evaluated in neonates, such as head circumference, length, weight, and Apgar scores, are somehow related to their neurocognitive performance. METHODS: We evaluated 77 CHD patients (43 males) aged from 13 to 18 years old (mean = 15.04 ± 1.86), 46 cyanotic, 23 with tetralogy of Fallot (TF), 23 with transposition of the great arteries (TGA) and 31 acyanotic with ventricular septal defect (VSD) enrolled in this study. The control group included 16 healthy children (11 males) ages ranging from 13 to 18 years old (mean = 15.69 years ± 1.44 years). All assessment measures for CHD patients were once obtained in a tertiary hospital; the control group was evaluated in school. Neuropsychological assessment included Wechsler's Digit Test, direct and reverse (WDD and WDR) and Symbol Search, Rey's Complex Figure (RCF), BADS's Key Searching Test, Color-Word Stroop Test (CWS), Trail Making Test (TMT), and Logical Memory Task (LMT). We evaluated some fetal parameters, such as head circumference, weight and length assessed at birth, and neonatal parameters, such as Apgar scores at 1 and 5 minutes after birth. We also registered some surgical parameters, such as the age at first operation and the number of surgeries. RESULTS: CHD patients compared with control group showed lower scores on every test, except for logical memory task. Patients with VSD when compared with patients with TF and TGA showed better results in all neuropsychological tests, although the only significant differences were in RCF, copy (F = 4936; P = .010). Several correlations were apparent between fetal/neonatal parameters and neuropsychological abilities in each type of CHD. However, head circumference at birth stands as the main correlation with cognitive development later on in all kinds of CHD (WDD: rho = .339, P = .011; RCF, copy: rho = 0.297, P = .027; CWS, interference: rho = 0.283, P = .036; TMT-A: rho = -0.321, P = .017). We analyzed the predicting relevance of several variables to cognitive performance of adolescents with CHD and confirmed that "cyanosis" stands as the main predictor (â = -4.758; t = -2.622; P = .011). CONCLUSIONS: Adolescents with CHD have worse neuropsychological performance than the control group, mainly the cyanotic patients. Fetal circulation seems to have impact on cerebral and somatic growth, predicting cognitive impairment in adolescents with CHD.

[Long term psychosocial outcomes of congenital heart disease in adolescents and young adults].

OBJECTIVE: Congenital heart disease (CHD) is a chronic illness with a high frequency in the worldwide population, and is normally diagnosed at birth or in uterus. Because of better conditions in diagnosis and early medical and surgical treatment, patients have survival rates of 90% and go further and further in life, facing different challenges in life cycle. In this study, we tested the effects of different demographic, clinical and psychosocial variables on the perception of quality of life (QOL), on psychosocial adjustment (PSA) and psychiatric morbidity (PM) of adolescents and young adults with CHD. We aimed to evaluate QOL, PM and PSA of adolescents and young adults with CHD and to determine which variables (demographic, clinical, and psychosocial) play a role in buffering stress and promoting resilience and which ones have a detrimental effect. METHODS: The study enrolled 150 CHD patients (87 males and 63 females), 12 to 26 years (17.45±3.373 years). The participants were interviewed regarding social support, family educational style, self-image, demographic information and physical limitations. They responded to questions in a standardized psychiatric interview (SADS-L) and completed self-reports questionnaires for assessment of QOL (WHOQOL-BREF) and PSA (YSR/ASR). RESULTS: We found a 18.7% lifetime prevalence of psychopathology in our participants (25.4% in females and 13.8% in males). 57.1% had retentions in school (1.53±0.804 year). The perception of QOL of CHD patients is better compared to the Portuguese population in the social relationships, environmental, physical and general dimensions. However, it is worse in female CHD patients and patients with poor academic performance and social support as well as in patients with complex or cyanotic CHD, moderate-to-severe residual lesions and physical limitations, and undergoing surgery. All of these variables, except presence of cyanosis, are also associated to a worse PSA. CONCLUSIONS: Female patients and patients with poor academic performance and poor social support refer worse PSA and QOL.
